        period
        commencing on June 29, 2010 and ending on June 30, 2017; provided,

        shall terminate.

       

      (b)  Exercise
        Procedure.

       

      (i)  This
        Warrant shall be exercised, to the extent of the number of shares of Common
        Stock described in clause
        (D)
        below,
        when the Company has received all of the following items (the “Exercise
        Time”):

       

      (A)  the
        original executed copy of this Warrant;

       

      (B)  a
        completed Exercise Agreement, in the form of Exhibit
        A,
        which
        shall be dated the actual date of execution thereof;

       

      (C)  if
        the
        Registered Holder is not ABN AMRO Bank N.V., an Assignment in the form of
        Exhibit
        B,
        evidencing the assignment(s) of this Warrant; and

       

      (D) subject
        to clause
        (ii)
        below, a
        cashier’s check payable to the Company or a wire transfer of immediately
        available funds to an account specified by the Company in an amount equal
        to the
        product of the Exercise Price

       

      
        
          
          

        

        
          -1-

          
            

          

        

        
          
          

        

      

       

      multiplied
        by the number of shares of Common Stock being purchased upon such
        exercise.

       

      (ii)  Notwithstanding
        Section
        1(b)(i)(D)
        above,
        at the election of the Registered Holder, which election shall be set forth
        in
        the Exercise Agreement, the number of shares of Common Stock being purchased
        upon exercise of the Warrant shall be equal to the quotient obtained by dividing
        (a) the product of (x) the Market Price at such Exercise Time less the Exercise
        Price, multiplied by (y) the number of shares of Common Stock as to which
        the
        Registered Holder elects to be issued under this clause
        (ii)
        (which
        election shall reduce the number of shares of Common Stock available for
        any
        subsequent exercise), by (b) the Market Price at such Exercise Time. The
        number
        of shares issued pursuant to this clause
        (ii)
        shall be
        excluded from the calculation of the amount paid pursuant to Section
        1(b)(i)(D)
        above.

       

      (iii)  Certificates
        for shares of Common Stock purchased upon exercise of this Warrant shall
        be
        delivered by the Company to the Registered Holder as soon as reasonably
        practicable, and in any event within five business days after the Company’s
        transfer agent delivers the certificates to the Company.

       

      (iv)  The
        Common Stock issuable upon exercise of this Warrant shall be deemed to have
        been
        issued to the Registered Holder at the Exercise Time, and the Registered
        Holder
        shall be the record holder of such Common Stock at the Exercise
        Time.

       

      (v)  If
        this
        Warrant is exercised in part, the Company shall, at the time of delivery
        of the
        certificate or certificates for Common Stock, unless this Warrant has then
        expired, issue and deliver to the Registered Holder a new Warrant evidencing
        the
        rights of the Registered Holder to purchase the aggregate number of shares
        of
        Common Stock for which this Warrant shall not have been exercised, and this
        Warrant shall be cancelled.

       

      (vi)  The
        issuance of certificates for shares of Common Stock upon exercise of this
        Warrant shall be made without charge to the Registered Holder for costs incurred
        by the Company in connection with such exercise and the related issuance
        of
        shares of Common Stock, except the Registered Holder shall pay any issuance
        taxes in respect thereof.

       

      (vii)  The
        Company shall not close its books against the transfer of this Warrant or
        of any
        shares of Common Stock issued or issuable upon exercise of this Warrant in
        any
        manner that interferes with the timely exercise of this Warrant. 

       

      (viii)     The
        Company shall at all times reserve and keep available out of its authorized
        but
        unissued shares of Common Stock solely for the purpose of issuance upon exercise
        of this Warrant, such number of shares of Common Stock as are then issuable
        upon
        exercise of this Warrant. All shares of Common Stock which are so issuable
        shall, when issued, be duly and validly issued, and upon payment of the Exercise
        Price therefor, shall be fully paid and nonassessable and free from all taxes,
        liens and charges. The Company shall take all such actions as may be necessary
        to assure that all such shares of

       

      
        
          
          

        

        
          -2-

          
            

          

        

        
          
          

        

      

       

      Common
        Stock may be so issued without violation of any applicable law or governmental
        regulation or any requirements of any domestic securities exchange upon which
        shares of Common Stock are listed (except for official notice of issuance,
        which
        shall be immediately delivered by the Company upon each such
        issuance).

       

      (ix)  Upon
        any
        exercise of this Warrant, the Company will require customary representations
        from the Registered Holder prior to the issuance of the Common Stock to assure
        that the issuance of the Common Stock hereunder shall not require registration
        or qualification under the Securities Act or any state securities
        laws.

       

      (c)  Fractional
        Shares.
        Except
        as set forth in the proviso to the following sentence, the Company shall
        not be
        required to issue fractional shares of Common Stock upon the exercise of
        any
        Warrant. Upon the exercise of any Warrant, there shall be paid to the holder
        thereof, in lieu of any fractional share of Common Stock resulting therefrom,
        an
        amount of cash equal to the product of: (i) the fractional amount of such
        shares, times (ii) the Market Price, as determined on the trading day
        immediately prior to the date of exercise of such warrant; provided
        that, if
        such payment would exceed $100.00, the Company shall issue fractional shares
        upon exercise of the Warrant.

       

      (d)  Legends.
        

       

      (i)    Until
        the
        shares of Common Stock issued upon exercise of the Warrant have been Registered
        under the Securities Act and registered and qualified under the securities
        laws
        of any applicable state(s), the Company shall cause each certificate evidencing
        any such shares of Common Stock issued upon exercise of Warrants which have
        not
        been Registered to bear the following legend:

       

      THE
        SHARES EVIDENCED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE
        SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), OR UNDER THE
        SECURITIES LAWS OF ANY STATE. THE SHARES MAY NOT BE OFFERED, SOLD, ASSIGNED,
        TRANSFERRED, PLEDGED OR HYPOTHECATED OR OTHERWISE DISPOSED OF IN THE ABSENCE
        OF
        AN EFFECTIVE REGISTRATION STATEMENT UNDER THE ACT, AND SUCH REGISTRATION
        OR
        QUALIFICATION AS MAY BE NECESSARY UNDER THE SECURITIES LAWS OF ANY STATE,
        OR AN
        OPINION OF COUNSEL SATISFACTORY TO THE COMPANY THAT SUCH REGISTRATION OR
        QUALIFICATION IS NOT REQUIRED.

       

      (ii)    Upon
        Registration under the Securities Act, and registration and qualification
        under
        the securities laws of any applicable state(s), of any shares of Common Stock
        issued upon exercise of Warrants, the Company will promptly exchange the
        certificates representing such shares for like certificates without the legend
        described in clause
        (i)
        above.

       

      
        
          
          

        

        
          -3-

          
            

          

        

        
          
          

        

      

       

      Section
        2.    Restrictions
        on Transfer.
        The
        Registered Holder shall not sell, transfer, assign, pledge or otherwise dispose
        of (“Transfer”)
        any
        interest in this Warrant unless all of the following conditions are
        satisfied:

       

      (a)    such
        Registered Holder and the transferee shall deliver to the Company written
        notice
        of the Transfer five business days prior to the effectiveness of the Transfer
        and shall execute an Assignment substantially in the form set forth in
Exhibit
        B,
        a copy
        of which shall be delivered to the Company within 30 days after the date
        of
        execution of such Assignment; 

       

      (b)    such
        Transfer has been registered or is exempt from registration under the Securities
        Act and any applicable state securities laws; and

       

      (c)    the
        Company shall have received from counsel reasonably satisfactory to the Company
        a legal opinion to the effect that such Transfer complies with the Securities
        Act and any applicable state securities laws.

       

      Section
        3.    Adjustment
        of Exercise Price and Number of Shares.
        In
        order to prevent dilution of the rights granted under this Warrant, the Exercise
        Price shall be subject to adjustment from time to time as provided in this
        Section
        3,
        and the
        number of shares of Common Stock issuable upon exercise of this Warrant shall
        be
        subject to adjustment from time to time as provided in this Section
        3.

       

      (a)    Subdivision
        or Combination of Common Stock.
        If the
        Company at any time subdivides (by any stock split, stock dividend,
        recapitalization or otherwise) one or more classes of its outstanding shares
        of
        Common Stock into a greater number of shares, the Exercise Price in effect
        immediately prior to such subdivision shall be proportionately decreased
        and the
        number of shares of Common Stock issuable upon exercise of this Warrant shall
        be
        proportionately increased. If the Company at any time combines (by reverse
        stock
        split or otherwise) one or more classes of its outstanding shares of Common
        Stock into a smaller number of shares, the Exercise Price in effect immediately
        prior to such combination shall be proportionately increased and the number
        of
        shares of Common Stock issuable upon exercise of this Warrant shall be
        proportionately decreased.

       

      (b)    Dividends
        and Stock Repurchases.
        If the
        Company shall declare, pay or distribute dividends upon the Common Stock
        (excluding a dividend referred to in Section
        3(a))
        in any
        calendar year which, in the aggregate, exceed 5% of the Market Price of the
        Common Stock on the date of declaration, then the Exercise Price shall be
        decreased by multiplying the Exercise Price immediately prior to such decrease
        by a fraction, (A) the denominator of which equals the product of (1) the
        Exercise Price immediately prior to such decrease multiplied by (2) the number
        of shares of Common Stock outstanding at such time and (B) the numerator
        of
        which equals the denominator as determined pursuant to clause
        (A)
        above
        minus the amount by which all such dividends for such calendar year, in the
        aggregate, exceed 5% of the Market Price of the Common Stock on such date
        of
        declaration. Any such decrease shall take effect on the record date for the
        dividend. If the Company shall repurchase shares of Common Stock for a per
        share
        consideration which exceeds the Market Price in effect immediately prior
        to the
        first such repurchase, then the Exercise Price shall be adjusted in accordance
        with the foregoing provisions, as if, in lieu of such repurchase, the Company
        had (i) paid a dividend having a fair

       

      
        
          
          

        

        
          -4-

          
            

          

        

        
          
          

        

         

        market
          value equal to the fair market value of all property and cash paid for
          such
          repurchased shares and (ii) effected a reverse split of the Common Stock in
          the proportion necessary to reduce the number of shares of Common Stock
          outstanding from (A) the number of shares outstanding immediately prior
          to the
          first such repurchase to (B) the number of shares outstanding immediately
          following all such repurchases.

      

       

      (c)  Minimum
        Adjustment.
        In the
        event that any adjustment made pursuant to this Section
        3
        would
        result in an adjustment to the Exercise Price of less than $0.01 per share
        of
        Common Stock, no such adjustment shall be made and such adjustment shall
        be
        carried forward and shall be made at the time and together with the next
        subsequent adjustment which, together with any adjustments so carried forward,
        shall amount to an adjustment in the Exercise Price of $0.01 or more per
        share
        of Common Stock; provided
        that,
        upon any adjustment of the Exercise Price resulting from (i) the declaration
        of
        a dividend upon, or the making of any distribution in respect of, any securities
        of the Company payable in Common Stock or Convertible Securities or (ii)
        the
        reclassification, by subdivision, combination or otherwise, of the outstanding
        shares of Common Stock into a greater or smaller number of shares, the $0.01
        per
        share number (or such number as last adjusted) shall be proportionately
        adjusted.

       

      (d)  Reorganization,
        Reclassification, Consolidation, Merger or Sale.
        Any
        recapitalization, reorganization, reclassification, consolidation, merger,
        sale
        of all or substantially all of the Company’s assets or other transaction that is
        effected in such a way that holders of Common Stock are entitled to receive
        (either directly or upon subsequent liquidation) stock, securities or assets
        with respect to or in exchange for Common Stock is referred to herein as
        an
“Organic
        Change.”
Prior
        to the consummation of any Organic Change, the Company shall make appropriate
        provision to insure that the Registered Holders shall thereafter have the
        right
        to acquire and receive in lieu of or in addition to (as the case may be)
        the
        shares of Common Stock immediately theretofore issuable upon exercise of
        each
        Warrant, such shares of stock, securities or assets as may be issued or payable
        with respect to or in exchange for the number of shares of Common Stock
        immediately theretofore issuable upon exercise of each Warrant had such Organic
        Change not taken place. In any such case, the Company shall make appropriate
        provision with respect to the Registered Holders’ rights and interests to insure
        that the provisions of this Section 3
        shall
        thereafter be applicable to each Warrant. The Company shall not effect any
        such
        consolidation, merger or sale, unless prior to the consummation thereof,
        the
        successor entity (if other than the Company) resulting from consolidation
        or
        merger or the corporation purchasing such assets assumes by written instrument,
        the obligation to deliver to the Registered Holders such shares of stock,
        securities or assets as, in accordance with the foregoing provisions, the
        Registered Holders may be entitled to acquire. The Company may, at its option,
        satisfy its obligation under this Section
        3(d)
        by
        treating the Organic Change as an exercise in full of the Warrant by the
        Registered Holders pursuant to Section
        l(b)(ii)
        immediately prior to the Organic Change. In such case, the shares of Common
        Stock or other securities issued to a Registered Holder shall not be
        transferable by such Registered Holder, without the written consent of the
        Company, until the third anniversary of the original issuance date of the
        Warrant.

      (i)    Promptly
        upon any adjustment of the Exercise Price, the Company shall give written
        notice
        thereof to the Registered Holders, setting forth in reasonable detail and
        certifying the calculation of such adjustment.

       

      (ii)    The
        Company shall give written notice to the Registered Holders at least 20 days
        prior to the date on which the Company closes its books or takes a record
        (A)
        with respect to any dividend or distribution upon the Common Stock, (B) with
        respect to any pro rata subscription offer to holders of Common Stock or
        (C) for
        determining rights to vote with respect to any Organic Change, dissolution
        or
        liquidation.

       

      (iii)    The
        Company shall also give written notice to the Registered Holders at least
        20
        days prior to the date on which any Organic Change, dissolution or liquidation
        shall take place, if notice was not previously provided pursuant to Section
        3(e)(ii).

      (a)  Due
        Organization.
        The
        Company has been duly organized and is validly existing and in good standing
        as
        a limited liability company under the laws of the State of Nevada, and is
        qualified to do business and in good standing in all jurisdictions where
        such
        qualification is necessary to carry on its business as now conducted or as
        proposed by it to be conducted on the date hereof, except where failure to
        so
        qualify would not have a material adverse effect on the financial position
        or
        results of operations of the Company or any adverse effect on the ability
        of the
        Company to carry out its obligations under this Warrant.

       

      (b)  Due
        Authorization.
        The
        Company has full power and authority to issue this Warrant. The execution,
        delivery and issuance by the Company of this Warrant have been duly and validly
        approved by all necessary limited liability company action and no other actions
        or proceedings on the part of the Company are necessary to authorize this
        Warrant. This Warrant constitutes the legal, valid and binding obligation
        of the
        Company, enforceable against the Company in accordance with its terms, except
        as
        such enforceability may be limited by (i) applicable bankruptcy,
        insolvency, moratorium, reorganization or similar laws in effect which affect
        the enforcement of creditors’ rights generally, (ii) general principles of
        equity (regardless of whether a proceeding is considered at law or in equity),
        or (iii) with respect to any rights to indemnity or contribution hereunder,
        by applicable securities laws and public policy considerations.

       

      (c)     
        Capitalization.

        securities

       

      
        
          
          

        

        
          -8-

          
            

          

        

        
          
          

        

      

       

      convertible
        or exchangeable for shares of Common Stock or any rights or options to subscribe

        shares.

       

      (d)  Issuance
        of Shares.
        The
        Common Stock issuable hereunder, when issued in accordance with the provisions
        of this Warrant, will be duly and validly authorized and issued and will

      Section
        6.    No
        Voting Rights; Limitations of Liability.
        This
        Warrant shall not entitle any Registered Holder to any voting rights or other
        rights as a stockholder of the Company. No provision hereof, in the absence
        of
        affirmative action by a Registered Holder to purchase Common Stock, and no
        enumeration herein of the rights or privileges of the Registered Holders
        shall
        give rise to any liability of a Registered Holder for the Exercise Price
        of
        Common Stock issuable upon exercise of this Warrant or as a stockholder or
        other
        security holder of the Company.

       

      Section
        7.    Piggyback
        Registrations; Tag-Along Rights.

       

      (a)  Subject
        to applicable stock exchange rules and securities regulations, the Company
        proposes to register any of its common equity securities or any securities
        convertible into its common equity securities under the Securities Act (other
        than pursuant to (i) a registration on Form S-4 or any successor form, or
        (ii) an offering of securities in connection with an employee benefit, share
        dividend, share ownership or dividend reinvestment plan) and the registration
        form to be used may be used for the registration of Registrable Shares, the
        Company will give prompt written notice to all holders of Registrable Shares
        of
        its intention to effect such a registration (each a “Piggyback
        Notice”)
        and,
        subject to Section
        7(c)
        below,
        the Company will include in such registration all Registrable Shares with
        respect to which the Company has received written requests for inclusion
        therein
        within 15 days after the date of sending the Piggyback Notice (a “Piggyback
        Registration”),
        unless, if the Piggyback Registration is not an underwritten offering, the
        Company in its reasonable judgement determines that, or in the case of an
        underwritten Piggyback Registration, the managing underwriters advise the
        Company in writing that in their opinion, the inclusion of Registrable Shares
        would materially adversely interfere with such offering, materially adversely
        affect the Company’s securities in the public markets, or otherwise materially
        adversely affect the Company. Nothing herein shall affect the right of the
        Company to withdraw any such registration in its sole discretion.

       

      (b)    If
        a
        Piggyback Registration is a primary registration on behalf of the Company
        and,
        if the Piggyback Registration is not an underwritten offering, the Company
        in
        its reasonable judgment determines that, or in the case of an underwritten
        Piggyback Registration, the managing underwriters advise the Company in writing
        that in their opinion, the number of securities requested to be included
        in such
        registration exceeds the number which can be sold in an orderly manner within
        a
        price range acceptable to the Company, the Company will include in

       

      
        
          
          

        

        
          -9-

          
            

          

        

        
          
          

        

      

       

      (b)  such
        registration (i) first, the securities the Company proposes to sell and (ii)
        second, the Registrable Shares requested to be included in such Registration
        and
        any other securities requested to be included in such registration, pro rata
        among the holders of Registrable Shares requesting such registration and
        the
        holders of such other securities on the basis of the number of shares of
        Common
        Stock requested for inclusion in such registration by each such
        holder.

       

      (c)  If
        a
        Piggyback Registration is a secondary registration on behalf of holders of
        the
        Company’s securities other than the holders of Registrable Shares, and, if the
        Piggyback Registration is not an underwritten offering, the Company in its
        reasonable judgment determines that, or in the case of an underwritten Piggyback
        Registration, the managing underwriters advise the Company in writing that
        in
        their opinion, the number of securities requested to be included in such
        registration exceeds the number which can be sold in an orderly manner in
        such
        offering within a price range acceptable to the holders initially requesting
        such registration, the Company will include in such registration the securities
        requested to be included therein by the holders requesting such registration
        and
        the Registrable Shares requested to be included in such registration, pro
        rata
        among the holders of securities requesting such registration on the basis
        of the
        number of shares of Common Stock requested for inclusion in such registration
        by
        each such holder.

       

      (d)  In
        the
        case of an underwritten Piggyback Registration, the Company will have the
        right
        to select the investment banker(s) and manager(s) to administer the offering.
        If
        requested by the underwriters for any underwritten offerings by Registered
        Holders, under a registration requested pursuant to Section
        7(a),
        the
        Company will enter into a customary underwriting agreement with such
        underwriters for such offering, to contain such representations and warranties
        by the Company and such other terms which are customarily contained in
        agreements of this type. The Registered Holders shall be a party to such
        underwriting agreement and may, at their option, require that any or all
        of the
        conditions precedent to the obligations of such underwriters under such
        underwriting agreement be conditions precedent to the obligations of Registered
        Holders. The Registered Holders shall not be required to make any
        representations or warranties to or agreement with the Company or the
        underwriters other than customary representations, warranties or agreements
        regarding the Registered Holders and the Registered Holders’ intended method of
        distribution and any other representations or warranties required by
        law.

       

      (e)    If
        any or
        all of the Designated Shareholders propose to effect a Sale to any person
        (the
“Purchaser”),
        or
        agree to participate with other shareholders in any Sale, of all or less
        than
        all of the Common Stock held by the Designated Shareholders (the “Tag-Along
        Purchase Offer”),
        the
        Designated Shareholders shall offer each and every one of the Registered
        Holders
        and the holders of Common Stock originally issued upon the exercise of Warrants
        the opportunity to sell to the Purchaser the Tag-Along Portion of their Common
        Stock for the same consideration per share and otherwise on the same terms
        and
        conditions (except to the extent set forth in Section
        7(d))
        upon
        which the Designated Shareholders sell their Common Stock; provided
        that the
        Registered Holders or holders of Common Stock originally issued upon the
        exercise of Warrants shall not be required to exercise Warrants or sell shares
        of Common Stock, except simultaneously with the consummation of the Sale
        and
        only to the extent that such shares are to be included in the Sale. The
        Tag-Along Portion shall be the greater of (A) 1000 shares of Common Stock
        or (B) that number of shares of Common Stock issuable to or held by
        such

       

      
        
          
          

        

        
          -10-

          
            

          

        

        
          
          

        

      

       

      (e)  Registered
        Holder or holder which is equal to (x) the total number of shares of Common
        Stock issuable upon the exercise of Warrants held of record by such Registered
        Holder or held of record by a holder of Common Stock originally issued upon
        the
        exercise of Warrants as of the date that the Tag-Along Notice is provided
        in
        accordance with Section
        7(f)
        below
multiplied
        by (y) a
        fraction the numerator of which is the total number of shares of Common Stock
        that the Designated Shareholders propose to sell as set forth in such Tag-Along
        Notice and the denominator of which is the total number of shares of Common
        Stock held directly or indirectly by the Designated Shareholders as of such
        date
        (the “Tag-Along
        Portion”).

       

      (f)    The
        Designated Shareholders shall cause the Tag-Along Purchase Offer described
        in
Section
        7(e)
        above to
        be reduced to writing and shall provide a written notice (the “Tag-Along
        Notice”)
        of the
        Tag-Along Purchase Offer to the Registered Holders and to the holders of
        Common
        Stock originally issued upon the exercise of Warrants. The Tag-Along Notice
        shall contain written notice of the Designated Shareholders’ offer to the
        Registered Holders and to the holders of Common Stock originally issued upon
        the
        exercise of Warrants to sell all or the Tag-Along Portion of their shares
        of
        Common Stock, as the case may be, setting forth the consideration per share
        to
        be paid by the Purchaser and the other terms and conditions of the Tag-Along
        Purchase Offer. No later than 20 days (or such longer period, if applicable,
        as
        would terminate coincidentally with the expiration of any waiting period
        under
        the Hart-Scott-Rodino Antitrust Improvements Act of 1976) after receipt of
        the
        Tag-Along Notice or in a subsequent notice from the Designated Shareholders
        if
        the Designated Shareholders offer the Registered Holders or the holders of
        Common Stock originally issued upon the exercise of Warrants the opportunity
        to
        sell all or the Tag-Along Portion of their Warrants and shares of Common
        Stock,
        each of the Registered Holders or holders who elects to participate in such
        Sale
        shall deliver to the Designated Shareholders Warrants or certificates
        representing all the shares of Common Stock to be sold by such Registered
        Holders or holders, duly endorsed in blank for exercise or transfer, together
        with all other documents required to be executed in connection with such
        Tag-Along Purchase Offer or, if such delivery is not permitted by applicable
        law, an unconditional agreement to deliver such Warrants or shares of Common
        Stock pursuant to this Section
        7(f)
        simultaneously with the consummation of such Tag-Along Purchase Offer against
        delivery to such Registered Holder or holder of the consideration therefor.
        In
        the event that a Registered Holder or a holder of shares of Common Stock
        originally issued upon the exercise of Warrants receives a Tag-Along Notice
        pursuant to this Section
        7(f),
        such
        Registered Holder and such holder agree to use their respective best efforts,
        in
        good faith and in a timely manner, to take, or cause to be taken, all action
        and
        to do, or cause to be done, all things necessary, proper or advisable, under
        applicable laws and regulations (including, without limitation, to ensure
        that
        all appropriate legal and other requirements are met and all consents of
        third
        Persons are obtained), to consummate the proposed transactions contemplated
        by
        this Section
        7(f).
        In the
        event that the Designated Shareholders shall reach a binding agreement to
        effect
        a Tag-Along Purchase Offer pursuant to which the Company shall be merged
        with or
        into, or sell substantially all of its assets to, another person, each
        Registered Holder and each holder of shares of Common Stock originally issued
        upon the exercise of Warrants agrees that, in addition to any of the
        requirements of the immediately preceding sentence, such Registered Holder
        and
        such holder shall vote all of its shares of Common Stock issued upon the
        exercise of Warrants, in favor of the transaction; provided,
        that
        the Registered Holder shall not
        be
        required to exercise the Warrant.

       

      
        
          
          

        

        
          -11-

          
            

          

        

        
          
          

        

      

       

      (g)    If,
        for
        any reason, the Designated Shareholders determine they cannot complete the
        Sale,
        the Designated Shareholders shall return to each Registered Holder and each
        holder of shares of Common Stock all certificates representing Warrants or
        Common Stock that such Registered Holder or holder delivered for Sale pursuant
        hereto together with all other documents delivered pursuant hereto by such
        Registered Holders or holders, and all the restrictions on Sale or other
        disposition contained in this Warrant with respect to Common Stock shall
        again
        be in effect. 

       

      (h)    At
        the
        closing of the Sale pursuant to Sections
        7(e)
        and
(f),
        the
        consideration with respect to the shares of Common Stock of any Registered
        Holder or holder of shares of Common Stock sold pursuant hereto shall be
        paid
        directly to each Registered Holder or holder pursuant to written instructions
        of
        such Registered Holder or holder. The Designated Shareholders shall furnish
        such
        other evidence of the completion and time of completion of such Sale and
        the
        terms thereof as shall be reasonably requested by such Registered Holders
        or
        holders.

       

      (i)    If
        any or
        all of the Designated Shareholders propose to effect a Triggering Purchase
        of
        shares of Common Stock from any other shareholder or shareholders of the
        Company, then the provisions of Section
        7(e),
        (f),
        (g)
        and
(h)
        shall
        apply to such Triggering Purchase as if (x) such Triggering Purchase is
        deemed to be a “Sale”, (y) the Designated Shareholders are deemed to be the
“Purchaser”, and (z) the “Tag-Along Portion” shall mean that number of
        shares of Common Stock issuable to or held by a Registered Holder or holder
        which is equal to (x) the total number of shares of Common Stock issuable
        upon
        the exercise of Warrants held of record by such Registered Holder or held
        of
        record by a holder of Common Stock originally issued upon the exercise of
        Warrants as of the date that the Tag-Along Notice is provided in accordance
        with
Section
        7(f)
        multiplied by (y) a fraction the numerator of which is the total number of
        shares of Common Stock that the Designated Shareholders propose to purchase
        from
        the selling shareholders as set forth in such Tag-Along Notice and the
        denominator of which is the total number of shares of Common Stock held directly
        or indirectly by all shareholders of the Company (other than the Designated
        Shareholders and the holders of Common Stock originally issued upon exercise
        of
        Warrants) as of such date. For purposes hereof, a “Triggering
        Purchase”
shall
        be the purchase by any or all of the Designated Shareholders of not less
        than
        100,000 shares of Common Stock held by any other shareholder or group of
        shareholders of the Company in one transaction or a series of transactions
        within a six-month period. 

       

      (j)    The
        provisions of Section
        7(e),
        (f),
        (g), (h)
        and
(i)
        shall
        cease to apply once the Company becomes a public reporting company under
        the
        Exchange Act; provided,
        however,
        that
        upon the occurrence of any Sale or any Triggering Purchase occurring after
        the
        Company becomes a public reporting company under the Exchange Act, the
        Registered Holders and holders of Common Stock originally issued upon the
        exercise of Warrants shall be entitled to sell to any shareholder of the
        Company
        or any third party, on terms and conditions as may be negotiated by such
        Registered Holders or holders, the Tag-Along Portion of their Common Stock
        during the sixty-day period following the occurrence of such Sale or such
        Triggering Purchase.

        8.    Registration
        Procedures.

       

      
        
          
          

        

        
          -12-

          
            

          

        

        
          
          

        

      

       

      (a)    The
        Company shall promptly notify the Registered Holders of the occurrence of
        the
        following events:

       

      (i)  when
        any
        registration statement relating to the Registrable Shares or post-effective
        amendment thereto filed with the Commission has become effective;

       

      (ii)  the
        issuance by the Commission of any stop order suspending the effectiveness
        of any
        registration statement relating to the Registrable Shares;

       

      (iii)  the
        Company’s receipt of any notification of the suspension of the qualification of
        any Registrable Shares covered by a registration statement for sale in any
        jurisdiction; and

       

      (iv)  the
        existence of any event, fact or circumstance that results in a registration
        statement or prospectus relating to Registrable Shares or any document
        incorporated therein by reference containing an untrue statement of material
        fact or omitting to state a material fact required to be stated therein or
        necessary to make the statements therein not misleading during the distribution
        of securities.

       

      The
        Company agrees to use its commercially reasonable efforts to obtain the
        withdrawal of any order suspending the effectiveness of any such registration
        statement or any state qualification as promptly as possible. Each Registered
        Holder agrees by acquisition of the Registrable Shares that upon receipt
        of any
        notice from the Company of the occurrence of any event of the type described
        in
Section
        8(a)(ii),
        (iii)
        or
(iv)
        to
        immediately discontinue its disposition of Registrable Shares pursuant to
        any
        registration statement relating to such securities until the Registered Holder’s
        receipt of written notice from the Company that such disposition may be
        made.

       

      (b)  The
        Company shall provide to the Registered Holders, at no cost to the Registered
        Holders, a copy of the registration statement and any amendment thereto used
        to
        effect the Registration of the Registrable Shares, each prospectus contained
        in
        such registration statement or post-effective amendment and any amendment
        or
        supplement thereto. The Company consents to the use of each such prospectus
        and
        any supplement thereto by the Registered Holders in connection with the offering
        and sale of the Registrable Shares covered by such registration statement
        or any
        amendment thereto. The Company shall also file a sufficient number of copies
        of
        each prospectus and any post-effective amendment or supplement thereto with
        the
        securities exchange or market on which the Common Stock is then listed so
        as to
        enable the Registered Holders to have the benefits of the prospectus delivery
        provisions of Rule 153 under the Securities Act.

       

      (c)  The
        Company agrees to use its commercially reasonable efforts to cause the
        Registrable Shares covered by a registration statement to be registered with
        or
        approved by such state securities authorities as may be necessary to enable
        the
        Registered Holders to consummate the disposition of such shares pursuant
        to the
        plan of distribution set forth in the registration statement.

       

      (d)    If
        any
        event, fact or circumstance requiring an amendment to a registration statement
        relating to the Registrable Shares or supplement to a prospectus relating
        to
        the

       

      
        
          
          

        

        
          -13-

          
            

          

        

        
          
          

        

      

       

      Registrable
        Shares shall exist, promptly upon becoming aware thereof the Company agrees
        to
        notify the Registered Holders and prepare and furnish to the Registered Holders
        a post-effective amendment to the registration statement or supplement to
        the
        prospectus or any document incorporated therein by reference or file any
        other
        required document so that, as thereafter delivered to the purchasers of the
        Registrable Shares, the prospectus will not contain an untrue statement of
        a
        material fact or omit to state any material fact required to be stated therein
        or necessary to make the statements therein not misleading.

       

      (e)  The
        Company agrees to use its commercially reasonable efforts (including the
        payment
        of any listing fees) to obtain the listing of all Registrable Shares covered
        by
        the registration statement on each securities exchange on which securities
        of
        the same class or series are then listed.

       

      (f)  The
        Company agrees to use its commercially reasonable efforts to comply with
        the
        Securities Act and the Exchange Act in connection with the offer and sale
        of
        Registrable Shares pursuant to a registration statement, and, as soon as
        reasonably practicable following the end of any fiscal year during which
        a
        registration statement effecting a Registration of the Registrable Shares
        shall
        have been effective, to make available to its security holders an earnings
        statement satisfying the provisions of Section 11(a) of the Securities
        Act.

       

      (g)  The
        Company agrees to cooperate with the selling Registered Holders to facilitate
        the timely preparation and delivery of certificates representing Registrable
        Shares to be sold pursuant to a Registration and not bearing any Securities
        Act
        legend; and enable certificates for such Registrable Shares to be issued
        for
        such numbers of shares and registered in such names as the Registered Holders
        may reasonably request at least two business days prior to any sale of
        Registrable Shares.

       

      Section
        9.    Expenses
        of Registration.
        The
        Company shall pay all Registration Expenses incurred in connection with the
        registration, qualification or compliance pursuant to Sections
        7
        and
8
        hereof.
        All Selling Expenses incurred in connection with the sale of Registrable
        Shares
        by any of the Registered Holders shall be borne by the Registered Holder
        selling
        such Registrable Shares. Each Registered Holder shall pay the expenses of
        its
        own counsel.

       

      Section
        10.    Indemnification.

       

      (a)    The
        Company will indemnify each Registered Holder, each Registered Holder’s officers
        and directors, and each person controlling such Registered Holder within
        the
        meaning of Section 15 of the Securities Act, against all expenses, claims,
        losses, damages and liabilities (including reasonable legal fees and expenses),
        arising out of or based on any untrue statement (or alleged untrue statement)
        of
        a material fact contained in any registration statement or prospectus relating
        to the Registrable Shares, or any amendment or supplement thereto, or based
        on
        any omission (or alleged omission) to state therein a material fact required
        to
        be stated therein or necessary to make the statements therein not misleading,
        provided, however, that
        the
        Company will not be liable in any such case to the extent that any such claim,
        loss, damage, liability or expense arises out of or is based on any untrue
        statement or omission or alleged untrue statement or omission, made in reliance
        upon and in conformity with information furnished in writing to the Company
        by
        such Registered Holder for inclusion therein.

       

      
        
          
          

        

        
          -14-

          
            

          

        

        
          
          

        

      

       

      (b)    Each
        Registered Holder will indemnify the Company, each of its directors and each
        of
        its officers who signs the registration statement, each underwriter, if any,
        of
        the Company’s securities covered by such registration statement, and each person
        who controls the Company or such underwriter within the meaning of
        Section 15 of the Securities Act, against all claims, losses, damages and
        liabilities (including reasonable legal fees and expenses) arising out of
        or
        based on any untrue statement (or alleged untrue statement) of a material
        fact
        contained in any such registration statement or prospectus, or any amendment
        or
        supplement thereto, or based on any omission (or alleged omission) to state
        therein a material fact required to be stated therein or necessary to make
        the
        statements therein not misleading, in each case to the extent, but only to
        the
        extent, that such untrue statement (or alleged untrue statement) or omission
        (or
        alleged omission) is made in such registration statement or prospectus, in
        reliance upon and in conformity with information furnished in writing to
        the
        Company by such Registered Holder for inclusion therein.

       

      (c)    Each
        party entitled to indemnification under this Section 10
        (the
“Indemnified
        Party”)
        shall
        give notice to the party required to provide indemnification (the “Indemnifying
        Party”)
        promptly after such Indemnified Party has actual knowledge of any claim as
        to
        which indemnity may be sought, but the omission to so notify the Indemnifying
        Party shall not relieve it from any liability which it may have to the
        Indemnified Party pursuant to the provisions of this Section 10
        except
        to the extent of the actual damages suffered by such delay in notification.
        The
        Indemnifying Party shall assume the defense of such action, including the
        employment of counsel to be chosen by the Indemnifying Party to be reasonably
        satisfactory to the Indemnified Party, and payment of expenses. The Indemnified
        Party shall have the right to employ its own counsel in any such case, but
        the
        legal fees and expenses of such counsel shall be at the expense of the
        Indemnified Party, unless the employment of such counsel shall have been
        authorized in writing by the Indemnifying Party in connection with the defense
        of such action, or the Indemnifying Party shall not have employed counsel
        to
        take charge of the defense of such action or the Indemnified Party shall
        have
        reasonably concluded that there may be defenses available to it or them which
        are different from or additional to those available to the Indemnifying Party
        (in which case the Indemnifying Party shall not have the right to direct
        the
        defense of such action on behalf of the Indemnified Party), in any of which
        events such fees and expenses shall be borne by the Indemnifying Party. No
        Indemnifying Party, in the defense of any such claim or litigation, shall,
        except with the consent of each Indemnified Party, consent to entry of any
        judgment or enter into any settlement which does not include as an unconditional
        term thereof the giving by the claimant or plaintiff to such Indemnified
        Party
        of a release from all liability in respect to such claim or
        litigation.

       

      (d)    In
        no
        event shall any Registered Holder be liable for any expenses, claims, losses,
        damages or liabilities pursuant to this Section 10
        in
        excess of the net proceeds to such Registered Holder of any Registrable Shares
        sold by such Registered Holder.

       

      Section
        11.    Information
        to be Furnished by Registered Holders.
        Each
        Registered Holder shall furnish to the Company such information as the Company
        may reasonably request and as shall be required in connection with the
        Registration and related proceedings referred to in Section 8
        hereof.
        If any Registered Holder fails to provide the Company with such information
        within 15 days of receipt of the Company’s request, the Company’s obligations
        under Section 8
        hereof,
        as applicable, with respect to such Registered Holder or the Registrable
        Shares
        owned by

      such
        Registered Holder shall be suspended until such Registered Holder provides
        such
        information.

       

      Section
        12.    Rule
        144 Sales.

       

      (a)  If

        Act.

       

      (b)  In
        connection with any sale, transfer or other disposition by any Registered
        Holder
        of any Registrable Shares pursuant to Rule 144 under the Securities Act,

        Company covenants and agrees that, if at any time while this Warrant is still
        outstanding the Company is no longer subject to reporting requirements under
        the

        transaction that is similar to the foregoing. 

       

      (b)  The
        Company covenants and agrees that, if at any time while the Company is no
        longer
        subject to reporting requirements under the Exchange Act and this Warrant
        is
        outstanding, it will provide each Registered Holder and each holder of Common
        Stock issued upon exercise of Warrants, at the times and on the terms set
        forth

        appropriate, and on reasonable advanced notice, access to the Company’s books

    PROMISSORY
      NOTE

    

    December
      27, 2007

    

    In
      consideration for a series of loans made and to be made by Bonnie
      Septimus
      and/or
      her designees (the “Payee”) to SENTRA
      CONSULTING CORP., a
      Nevada
      corporation (the “Maker”), of up to an aggregate of One Hundred Thousand Dollars
      and 00/100 ($100,000; the “Principal Amount”), Maker promises to pay the Payee,
      on or before January 31, 2008 (the “Payment Date”), the Principal Amount and all
      interest accrued thereon as provided herein. 

    

    Interest
      shall accrue on the unpaid balance of the Principal Amount at a rate of twelve
      percent (12%) per annum (the “Interest Rate”). All interest payable hereunder
      shall be computed on the basis of actual days elapsed and shall be due and
      payable on the Payment Date.

    

    Maker
      shall have the right to prepay all or any portion of the outstanding Principal
      Amount and accrued interest thereon at any time without penalty or premium.
      All
      payments hereunder when paid shall be applied first to the payment of all
      accrued interest and the balance shall be applied to principal.

    

    At
      any
      time, Payee shall have the right to convert all or any portion of the
      outstanding Principal Amount and accrued interest thereon into shares of Maker’s
      Series A Convertible Preferred Stock under the terms and provisions as set
      forth
      in the Certificate of Designation for the Series A Convertible Preferred
      Stock.

    

    Notwithstanding
      any provision contained herein, the total liability of Maker for payment of
      interest pursuant hereto, including late charges, shall not exceed the maximum
      amount of such interest permitted by law to be charged, collected, or received
      from Maker, and if any payments by Maker include interest in excess of such
      a
      maximum amount, Payee shall apply such excess to the reduction of the unpaid
      principal amount due pursuant hereto, or if none is due, such excess shall
      be
      refunded.

    

    1.    Events
      of Default.
      In case
      one or more of the following events (each, an “Event of Default”) (whatever the
      reason for such Event of Default and whether it shall be voluntary or
      involuntary or be effected by operation of law or pursuant to any judgment,
      decree or order of any court or any order, rule or regulation of any
      administrative or governmental body) shall have occurred and be
      continuing:

     

    
      
        
        

      

      
        
        

        
          

        

      

      
        
        

      

    

    

    a.    Default
      in the payment, when due or declared due, of any principal or interest payments
      hereunder.

    

    b.    Maker
      makes a general assignment for the benefit of creditors; or, in the absence
      of
      such application, consent, acquiescence or action, a trustee, receiver or other
      custodian is appointed for Maker; or for a substantial part of the property
      of
      Maker; or any bankruptcy, reorganization, debt arrangement or other proceeding
      under any bankruptcy or insolvency law, or any dissolution or liquidation
      proceeding, is authorized or instituted by, or instituted against, Maker; or
      any
      warrant of attachment or similar legal process is issued against any substantial
      part of the property of Maker.

    

    then,
      in
      each case where an Event of Default occurs, the Payee, by notice in writing
      to
      Maker shall inform Maker of such Event of Default and if such default is not
      cured within ten business days from the date such notice is received by Maker,
      then Payee, may, at its option, declare the outstanding Principal Amount to
      be
      due and payable immediately, and upon any such declaration the same shall become
      immediately due and payable. 

    

    2.    Representations
      of Payee. The
      Payee
      hereby acknowledges, represents and warrants to, and agrees with, the Maker

      or in part, and no other person has a direct or indirect beneficial interest
      in
      this Note or any portion thereof. Further, the Payee does not have any contract,
      undertaking agreement or arrangement with any person to sell, transfer or grant
      participations to such person or to any third person, with respect to the Note,
      in whole or in part.

    

    b.    The
