Each Warrant entitles the Holder to purchase one Share.  If the Expiration Date is a day on which banking institutions are authorized by law to close, then this Purchase Warrant may be exercised on the next succeeding day which is not such a day in accordance with the terms herein. During the period commencing on the Commencement Date and ending on the Expiration Date, the Company agrees not to take any action that would terminate the Purchase Warrant. This Purchase Warrant is initially exercisable at $____ per Unit (120% of the price of the Units sold in the Offering) so purchased; provided, however, that upon the occurrence of any of the events specified in Section 6 hereof, the rights granted by this Purchase Warrant, including the exercise price per Unit and the number of Units to be received upon such exercise, shall be adjusted as therein specified. The term “Exercise Price” shall mean the initial exercise price or the adjusted exercise price, depending on the context.

2.1           Exercise Form. In order to exercise this Purchase Warrant, the exercise form attached hereto must be duly executed and completed and delivered to the Company, together with this Purchase Warrant and payment of the Exercise Price for the Units being purchased payable in cash (unless exercised pursuant to the terms of Section 2.3 below) by wire transfer of immediately available funds to an account designated by the Company or by certified check or official bank check. If the subscription rights represented hereby shall not be exercised at or before 5:00 p.m., Eastern time, on the Expiration Date, this Purchase Warrant shall become and be void without further force or effect, and all rights represented hereby shall cease and expire.

2.2           Legend.  Each certificate for the securities purchased under this Purchase Warrant shall bear a legend as follows unless such securities have been registered under the Securities Act of 1933, as amended (the “Act”):

“The securities represented by this certificate have not been registered under the Securities Act of 1933, as amended (the “Act”) or applicable state law. Neither the securities nor any interest therein may be offered for sale, sold or otherwise transferred except pursuant to an effective registration statement under the Act, or pursuant to an exemption from registration under the Act and applicable state law.”

2.3           Cashless Exercise.

2.3.1           Determination of Amount.  In lieu of the payment of the Exercise Price multiplied by the number of Units which this Purchase Warrant is exercisable in the manner required by Section 2.1, the Holder shall have the right (but not the obligation) to convert any exercisable but unexercised portion of this Purchase Warrant into Units (“Conversion Right”) as follows:  upon exercise of the Conversion Right, the Company shall deliver to the Holder (without payment by the Holder of any of the Exercise Price in cash) that number of shares of Units equal to the quotient obtained by dividing (x) the “Value” (as defined below) of the portion of the Purchase Warrant being converted by (y) the Current Market Price per Unit (as defined below). The “Value” of the portion of the Purchase Warrant being converted shall equal the remainder derived from subtracting (a) (i) the Exercise Price multiplied by (ii) the number of Units underlying the portion of this Purchase Warrant being converted from (b) the Current Market Price of a Unit multiplied by the number of Units underlying the portion of the Purchase Warrant being converted. As used herein, the term “Current Market Price” per Unit at any date shall mean (i) if the Units are listed on a national securities exchange or quoted on the Nasdaq Global Market, Nasdaq Capital Market or NASD OTC Bulletin Board (or successor exchange), the last sale price of the Units in the principal trading market for the Units as reported by the exchange, Nasdaq or the NASD, as the case may be, on the last trading day preceding the date in question; (ii) if the Units are not listed on a national securities exchange or quoted on the Nasdaq Global Market, Nasdaq Capital Market or the NASD OTC Bulletin Board (or successor exchange), but is traded in the residual over-the-counter market, the closing bid price for the Units on the last trading day preceding the date in question for which such quotations are reported by the Pink Sheets, LLC or similar publisher of such quotations; and (iii) if the fair market value of the Units cannot be determined pursuant to clause (i) or (ii) above, such price as the Board of Directors of the Company shall determine, in good faith based, among other things, on the current market price of the Company’s common stock and Warrants.

2.3.2           Mechanics of Cashless Exercise.  The cashless exercise right may be exercised by the Holder on any business day on or after the Commencement Date and not later than the Expiration Date by delivering the Purchase Warrant with the duly executed exercise form attached hereto with the cashless exercise section completed to the Company, exercising the cashless exercise right and specifying the total number of Units the Holder will purchase pursuant to such cashless exercise right.

Registration Rights

4.1

Demand Registration.

4.1.1           Grant of Right. The Company, upon written demand (a “Demand Notice”) of the Holder(s) of at least 51% of the Purchase Warrants and/or the underlying securities (“Majority Holders”), agrees to register (a “Demand Registration”), on one occasion, all or any portion of the Shares underlying the Purchase Warrants, including the Shares underlying the Warrants included in the Purchase Warrants (collectively the “Registrable Securities”). On such occasion, the Company will file a registration statement or a post-effective amendment to the Registration Statement covering the Registrable Securities within sixty (60) days after receipt of a Demand Notice and use its best efforts to have such registration statement or post-effective amendment declared effective promptly thereafter, subject to compliance with review by the Commission; provided, however, that the Company shall not be required to comply with a Demand Notice if the Company has filed a registration statement with respect to which the Holder is entitled to piggyback registration rights pursuant to Section 4.2 hereof and either: (i) the Holder has elected to participate in the offering covered by such registration statement or (ii) if such registration statement relates to an underwritten primary offering of securities of the Company, until the offering covered by such registration statement has been withdrawn or until thirty (30) days after such offering is consummated. The demands for registration may be made at any time during a period of five (5) years beginning six (6) months from the Effective Date. The Company covenants and agrees to give written notice of its receipt of the Demand Notice by any Holder(s) to all other registered Holders of the Purchase Warrants and/or the Registrable Securities within ten (10) days from the date of the receipt of such Demand Notice.  The Holders shall not effect more than two (2) Demand Registrations pursuant to this Section 4.1.

4.1.2           Effective Registration.  A registration will not count as a Demand Registration until the registration statement filed with the Commission with respect to such Demand Registration has been declared effective and the Company has complied with all of its obligations under hereunder with respect thereto; provided, however, that if, after such registration statement has been declared effective, the offering of Registrable Securities pursuant to a Demand Registration is interfered with by any stop order or injunction of the Commission or any other governmental agency or court, the registration statement with respect to such Demand Registration will be deemed not to have been declared effective, unless and until, (i) such stop order or injunction is removed, rescinded or otherwise terminated, and (ii) the Majority Holders thereafter elect to continue the offering.

4.1.3           Terms. The Company shall bear all fees and expenses attendant to the first Demand Registration pursuant to Section 4.1.1, including the reasonable and documented expenses of any legal counsel selected by the Holders to represent them in connection with the sale of the Registrable Securities, but the Holders shall pay any and all underwriting commissions or brokerage fees related to the Registrable Securities, if applicable. The Holders shall bear all fees and expenses (including all underwriting commissions and the expenses of any legal counsel selected by the Holders to represent them) in connection with the second Demand Registration described in Section 4.1.1 hereof. The Company agrees to use its best efforts to cause the filing required herein to become effective promptly and to qualify or register the Registrable Securities in such States as are reasonably requested by the Holder(s); provided, however, that in no event shall the Company be required to register the Registrable Securities in a State in which such registration would cause: (i) the Company to be obligated to register or license to do business in such State or submit to general service of process in such State, or (ii) the principal stockholders of the Company to be obligated to escrow their shares of capital stock of the Company. The Company shall use its best efforts to cause any registration statement filed pursuant to the demand right granted under Section 4.1.1 to remain effective for a period of at least twelve (12) consecutive months from the date that the Holders of the Registrable Securities covered by such registration statement are first given the opportunity to sell all of such securities. The Holders shall only use the prospectuses provided by the Company to sell the shares covered by such registration statements, and will immediately cease to use any prospectus furnished by the Company if the Company advises the Holder that such prospectus may no longer be used due to a material misstatement or omission.

4.2

“Piggy-Back” Registration.

4.2.1           Grant of Right. In addition to the demand rights of registration described in Section 4.1 hereof, the Holder shall have the right, for a period of five (5) years commencing six (6) months from the Effective Date, to include the Registrable Securities as part of any other registration of securities filed by the Company (other than in connection with a transaction contemplated by Rule 145(a) promulgated under the Act or pursuant to Form S-8 or any equivalent form); provided, however, that if, solely in connection with any primary underwritten public offering for the account of the Company, the managing underwriter(s) thereof shall, in its reasonable discretion, impose a limitation on the number of Shares underlying the Units which may be included in the registration statement because, in such underwriter(s)’ judgment, marketing or other factors dictate such limitation is necessary to facilitate public distribution, then the Company shall be obligated to include in such registration statement only such limited portion of the Registrable Securities with respect to which the Holder requested inclusion hereunder as the underwriter(s) shall reasonably permit. Any exclusion of Registrable Securities shall be made pro rata among the Holders seeking to include Registrable Securities in proportion to the number of Registrable Securities sought to be included by such Holders; provided, however, that the Company shall not exclude any Registrable Securities unless the Company has first excluded all outstanding securities, the holders of which are not entitled to inclusion of such securities in such registration statement or are not entitled to pro rata inclusion with the Registrable Securities.  The Holders shall be entitled to unlimited piggy-back demand registration rights pursuant to this Section 4.2.

4.2.2           Withdrawal.  Any holder of Registrable Securities may elect to withdraw such Holder’s request for inclusion of Registrable Securities in any piggy-back registration by giving written notice to the Company of such request to withdraw prior to the effectiveness of the registration statement. The Company (whether on its own determination or as the result of a withdrawal by persons making a demand pursuant to written contractual obligations) may withdraw a registration statement at any time prior to the effectiveness of the registration statement.  Notwithstanding any such withdrawal, the Company shall pay all expenses incurred by the Holders of Registrable Securities in connection with such piggy-back registration as provided in Section 4.2.3.

4.2.3           Terms.  The Company shall bear all fees and expenses attendant to registering the Registrable Securities pursuant to Section 4.2.1 hereof, including the reasonable and documented expenses of any legal counsel selected by the Holders to represent them in connection with the sale of the Registrable Securities, but the Holders shall pay any and all underwriting commissions or brokerage fees related to the Registrable Securities. In the event of such a proposed registration, the Company shall furnish the then Holders of outstanding Registrable Securities with not less than thirty (30) days written notice prior to the proposed date of filing of such registration statement. Such notice to the Holders shall continue to be given for each registration statement filed by the Company until such time as all of the Registrable Securities have been sold by the Holder. The holders of the Registrable Securities shall exercise the “piggy-back” rights provided for herein by giving written notice, within ten (10) days of the receipt of the Company’s notice of its intention to file a registration statement. The Company shall use its best efforts to cause any registration statement filed pursuant to the piggyback right granted under Section 4.2.1 to remain effective for a period of at least nine (9) consecutive months from the date that the Holders of the Registrable Securities covered by such registration statement are first given the opportunity to sell all of such securities.

4.3

General Terms.

4.3.1           Indemnification. The Company shall indemnify the Holder(s) of the Registrable Securities to be sold pursuant to any registration statement hereunder and each person, if any, who controls such Holders within the meaning of Section 15 of the Act or Section 20(a) of the Securities Exchange Act of 1934, as amended (“Exchange Act”), against all loss, claim, damage, expense or liability (including all reasonable attorneys’ fees and other expenses reasonably incurred in investigating, preparing or defending against litigation, commenced or threatened, or any claim whatsoever, whether arising out of any action between any of the Underwriters (as defined below) and the Company or between the any of the Underwriters and any third party or otherwise) to which any of them may become subject under the Act, the Exchange Act or otherwise, arising from such registration statement but only to the same extent and with the same effect as the provisions pursuant to which the Company has agreed to indemnify the Underwriters contained in Section 5.1 of the Underwriting Agreement between Maxim and the Company, dated as of _______________, 2010 (the “Underwriting Agreement”). As used herein, “Underwriters” shall mean, collectively, Maxim and the other underwriters named on Schedule 1 of the Underwriting Agreement for which Maxim is acting as representative. The Holder(s) of the Registrable Securities to be sold pursuant to the Offering, and their successors and assigns, shall severally, and not jointly, indemnify the Company, against all loss, claim, damage, expense or liability (including all reasonable attorneys’ fees and other expenses reasonably incurred in investigating, preparing or defending against any claim whatsoever) to which they may become subject under the Act, the Exchange Act or otherwise, arising from information furnished by or on behalf of such Holders, or their successors or assigns, in writing, for specific inclusion in such registration statement to the same extent and with the same effect as the provisions contained in Section 8 of the Underwriting Agreement pursuant to which the Underwriters have agreed to indemnify the Company.

4.3.2           Exercise of Purchase Warrants. Nothing contained in this Purchase Warrant shall be construed as requiring the Holder(s) to exercise their Purchase Warrants prior to or after the initial filing of any registration statement or the effectiveness thereof.

 

4.3.3           Documents Delivered to Holders. In the event of an underwritten public offering, the Company shall furnish to each underwriter of any such offering a signed counterpart, addressed to such underwriter, of: (i) an opinion of counsel to the Company, dated the date of the closing under the underwriting agreement, and (ii) a “cold comfort” letter dated the effective date of the registration statement with respect to the underwritten public offering and a letter dated the date of the closing under the underwriting agreement, signed by the independent public accountants who have issued a report on the Company’s financial statements included in such registration statement, in each case covering substantially the same matters with respect to such registration statement (and the prospectus included therein) and, in the case of such accountants’ letter, with respect to events subsequent to the date of such financial statements, as are customarily covered in opinions of issuer’s counsel and in accountants’ letters delivered to underwriters in underwritten public offerings of securities. The Company shall also deliver promptly to each Holder participating in the offering requesting the correspondence and memoranda described below and to the managing underwriter, if any, copies of all correspondence between the Commission and the Company, its counsel or auditors and all memoranda relating to discussions with the Commission or its staff with respect to the registration statement and permit each Holder and underwriter to do such investigation, upon reasonable advance notice, with respect to information contained in or omitted from the registration statement as it deems reasonably necessary to comply with applicable securities laws or rules of FINRA. Such investigation shall include access to books, records and properties and opportunities to discuss the business of the Company with its officers and independent auditors, all to such extent and at such times as any such Holder shall request.

4.3.4           Underwriting Agreement. The Company shall enter into an underwriting agreement with the managing underwriter(s), if any, selected by any Holders whose Registrable Securities are being registered pursuant to this Section 4, which managing underwriter shall be reasonably satisfactory to the Company. Such agreement shall be reasonably satisfactory in form and substance to the Company, each Holder and such managing underwriters, and shall contain such representations, warranties and covenants by the Company and such other terms as are customarily contained in agreements of that type used by the managing underwriter. The Holders shall be parties to any underwriting agreement relating to an underwritten sale of their Registrable Securities and may, at their option, require that any or all the representations, warranties and covenants of the Company to or for the benefit of such underwriters shall also be made to and for the benefit of such Holders. Such Holders shall not be required to make any representations or warranties to or agreements with the Company or the underwriters except as they may relate to such Holders, their Units and their intended methods of distribution.

4.3.5           Documents to be Delivered by Holder(s). Each of the Holder(s) participating in any of the foregoing offerings shall furnish to the Company a completed and executed questionnaire provided by the Company requesting information customarily sought of selling securityholders.

Should the registration or the effectiveness thereof required by Sections 4.1 and 4.2 hereof be delayed by the Company or the Company otherwise fails to comply with such provisions, the Holder(s) shall, in addition to any other legal or other relief available to the Holder(s), be entitled to obtain specific performance or other equitable (including injunctive) relief against the threatened breach of such provisions or the continuation of any such breach, without the necessity of proving actual damages and without the necessity of posting bond or other security.

5.

New Purchase Warrant to be Issued.

5.1           Partial Exercise or Transfer. Subject to the restrictions in Section 3 hereof, this Purchase Warrant may be exercised or assigned in whole or in part. In the event of the exercise or assignment hereof in part only, upon surrender of this Purchase Warrant for cancellation, together with the duly executed exercise or assignment form and funds sufficient to pay any Exercise Price and/or transfer tax if exercised pursuant to Section 2.1 hereto, the Company shall cause to be delivered to the Holder without charge a new Purchase Warrant of like tenor to this Purchase Warrant in the name of the Holder evidencing the right of the Holder to purchase the number of Units purchasable hereunder as to which this Purchase Warrant has not been exercised or assigned.

5.2           Lost Certificate. Upon receipt by the Company of evidence satisfactory to it of the loss, theft, destruction or mutilation of this Purchase Warrant and of reasonably satisfactory indemnification or the posting of a bond, the Company shall execute and deliver a new Purchase Warrant of like tenor and date. Any such new Purchase Warrant executed and delivered as a result of such loss, theft, mutilation or destruction shall constitute a substitute contractual obligation on the part of the Company.

6.

Adjustments.

6.1           Adjustments to Exercise Price and Number of Securities. The Exercise Price and the number of Shares underlying the Purchase Warrant shall be subject to adjustment from time to time as hereinafter set forth:

6.1.1           Stock Dividends; Split Ups. If after the date hereof, and subject to the provisions of Section 6.3 below, the number of outstanding Shares of the Company is increased by a stock dividend payable in Shares or by a split up of Shares or other similar event, then, on the effective day thereof, the number of Shares of the Company purchasable hereunder shall be increased in proportion to such increase in outstanding Shares.   In such case, the number of Shares, and the exercise price applicable thereto, underlying the Warrants underlying each of the Units purchasable hereunder shall be adjusted in accordance with the terms of the Warrants.

6.1.2           Aggregation of Shares. If after the date hereof, and subject to the provisions of Section 6.3, the number of outstanding Shares is decreased by a consolidation, combination or reclassification of Shares or other similar event, then, on the effective date thereof, the number of Shares purchasable hereunder shall be decreased in proportion to such decrease in outstanding Shares.  In such case, the number of Shares, and the exercise price applicable thereto, underlying the Warrants underlying each of the Units purchasable hereunder shall be adjusted in accordance with the terms of the Warrants.

6.1.3           Replacement of Securities upon Reorganization, etc. In case of any reclassification or reorganization of the outstanding Shares other than a change covered by Section 6.1.1 or 6.1.2 hereof or that solely affects the par value of such Shares, or in the case of any share reconstruction or amalgamation or consolidation of the Company with or into another corporation (other than a consolidation or share reconstruction or amalgamation in which the Company is the continuing corporation and that does not result in any reclassification or reorganization of the outstanding Shares), or in the case of any sale or conveyance to another corporation or entity of the property of the Company as an entirety or substantially as an entirety in connection with which the Company is dissolved, the Holder of this Purchase Warrant shall have the right thereafter (until the expiration of the right of exercise of this Purchase Warrant) to receive upon the exercise hereof, for the same aggregate Exercise Price payable hereunder immediately prior to such event, the kind and amount of shares of stock or other securities or property (including cash) receivable upon such reclassification, reorganization, share reconstruction or amalgamation, or consolidation, or upon a dissolution following any such sale or transfer, by a Holder of the number of Shares obtainable upon exercise of this Purchase Warrant immediately prior to such event; and if any reclassification also results in a change in Shares covered by Section 6.1.1 or 6.1.2, then such adjustment shall be made pursuant to Sections 6.1.1, 6.1.2 and this Section 6.1.3. The provisions of this Section 6.1.3 shall similarly apply to successive reclassifications, reorganizations, share reconstructions or amalgamations, or consolidations, sales or other transfers.

6.1.4           Changes in Form of Purchase Warrant. This form of Purchase Warrant need not be changed because of any change pursuant to this Section, and any Purchase Warrant issued after such change may state the same Exercise Price and the same number of Units as are stated in any Purchase Warrant initially issued pursuant to this Agreement. The acceptance by any Holder of the issuance of a new Purchase Warrant reflecting a required or permissive change shall not be deemed to waive any rights to an adjustment occurring after the Commencement Date or the computation thereof.

6.2           Substitute Purchase Warrant. In case of any consolidation of the Company with, or share reconstruction or amalgamation of the Company with or into, another corporation (other than a consolidation or share reconstruction or amalgamation which does not result in any reclassification or change of the outstanding Shares), the corporation formed by such consolidation or share reconstruction or amalgamation shall execute and deliver to the Holder a supplemental Purchase Warrant providing that the holder of each Purchase Warrant then outstanding or to be outstanding shall have the right thereafter (until the stated expiration of such Purchase Warrant) to receive, upon exercise of such Purchase Warrant, the kind and amount of shares of stock and other securities and property receivable upon such consolidation or share reconstruction or amalgamation, by a holder of the number of Units for which such Purchase Warrant might have been exercised immediately prior to such consolidation, share reconstruction or amalgamation, sale or transfer. Such supplemental Purchase Warrant shall provide for adjustments which shall be identical to the adjustments provided in Section 6.1. The above provision of this Section shall similarly apply to successive consolidations or share reconstructions or amalgamations.

6.3           Elimination of Fractional Interests. The Company shall not be required to issue certificates representing fractions of Units upon the exercise of this Purchase Warrant, nor shall it be required to issue scrip or pay cash in lieu of any fractional interests, it being the intent of the parties that all fractional interests shall be eliminated by rounding any fraction up or down, as the case may be, to the nearest whole number of Units or other securities, properties or rights.

7.           Reservation and Listing. The Company shall at all times reserve and keep available out of its authorized Shares, solely for the purpose of issuance upon exercise of the Purchase Warrants or any substitute Purchase Warrants issued pursuant to Section 6, such number of Units or other securities, properties or rights as shall be issuable upon the exercise thereof. The Company covenants and agrees that, upon exercise of the Purchase Warrants and payment of the Exercise Price therefor, in accordance with the terms hereby, all Shares underlying the Units and the Warrants and other securities issuable upon such exercise shall be duly and validly issued, fully paid and non-assessable and not subject to preemptive rights of any stockholder.  As long as the Purchase Warrants shall be outstanding, the Company shall use its best efforts to cause all Shares issuable upon exercise of the Purchase Warrants (including the Shares issuable upon exercise of the Warrants underlying the Purchase Warrants) to be listed (subject to official notice of issuance) on all securities exchanges (or, if applicable on the Nasdaq Global Market, the Nasdaq Capital Market, the OTC Bulletin Board or any successor trading market) on which the Shares issued to the public in the Offering may then be listed and/or quoted.

8.

Certain Notice Requirements.

8.1           Holder’s Right to Receive Notice. Nothing herein shall be construed as conferring upon the Holders the right to vote or consent or to receive notice as a stockholder for the election of directors or any other matter, or as having any rights whatsoever as a stockholder of the Company. If, however, at any time prior to the expiration of the Purchase Warrants and their exercise, any of the events described in Section 8.2 shall occur, then, in one or more of said events, the Company shall give written notice of such event at least fifteen days prior to the date fixed as a record date or the date of closing the transfer books for the determination of the stockholders entitled to such dividend, distribution, conversion or exchange of securities or subscription rights, or entitled to vote on such proposed dissolution, liquidation, winding up or sale. Such notice shall specify such record date or the date of the closing of the transfer books, as the case may be. Notwithstanding the foregoing, the Company shall deliver to each Holder a copy of each notice given to the other stockholders of the Company at the same time and in the same manner that such notice is given to the stockholders.

8.2           Events Requiring Notice. The Company shall be required to give the notice described in this Section 8 upon one or more of the following events: (i) if the Company shall take a record of the holders of its Shares for the purpose of entitling them to receive a dividend or distribution payable otherwise than in cash, or a cash dividend or distribution payable otherwise than out of retained earnings, as indicated by the accounting treatment of such dividend or distribution on the books of the Company, (ii) the Company shall offer to all the holders of its Shares any additional shares of capital stock of the Company or securities convertible into or exchangeable for shares of capital stock of the Company, or any option, right or warrant to subscribe therefor, or (iii) a dissolution, liquidation or winding up of the Company (other than in connection with a consolidation or share reconstruction or amalgamation) or a sale of all or substantially all of its property, assets and business shall be proposed.

8.3           Notice of Change in Exercise Price. The Company shall, promptly after an event requiring a change in the Exercise Price pursuant to Section 6 hereof, send notice to the Holders of such event and change (“Price Notice”).
