Section 2. Exercise.

a) Exercise of Warrant.

i. Exercise of the purchase rights represented by this Class B Warrant may be made, in whole or in part, at any time or times on or after the Initial Exercise Date and on or before the Termination Date by delivery to the Company (or such other office or agency of the Company as it may designate by notice in writing to the registered Holder at the address of the Holder appearing on the books of the Company) of a duly executed notice of exercise (“Notice of Exercise”) form attached hereto as Exhibit A; and, within 3 Trading Days of the date said Notice of Exercise is delivered to the Company, the Company shall have received payment of the aggregate Exercise Price of the Class B Warrant Shares thereby purchased by wire transfer or cashier’s check drawn on a United States bank. Notwithstanding anything herein to the contrary, the Holder shall not be required to physically surrender this Class B Warrant to the Company until the Holder has purchased all of the Class B Warrant Shares available hereunder and the Class B Warrant has been exercised in full, in which case, the Holder shall surrender this Class B Warrant to the Company for cancellation within 3 Trading Days of the date the final Notice of Exercise is delivered to the Company. Partial exercises of this Class B Warrant resulting in purchases of a portion of the total number of Warrant Shares available hereunder shall have the effect of lowering the outstanding number of Warrant Shares purchasable hereunder in an amount equal to the applicable number of Warrant Shares purchased. The Holder and the Company shall maintain records showing the number of Warrant Shares purchased and the date of such purchases. In the event of any dispute or discrepancy, the records of the Company shall be controlling and determinative in the absence of manifest error.

ii. In lieu of the payment methods set forth in Section 2(a)(i) above, the Holder may elect to exchange all or some of this Class B Warrant for shares of Common Stock equal to the value of the amount of the Class B Warrant being exchanged on the date of exchange. If Holder elects to exchange this Class B Warrant as provided in this Section 2(a)(ii), Holder shall tender to the Company the Class B Warrant for the amount being exchanged, along with written notice of Xxxxxx’s election to exchange some or all of the Class B Warrant, and the Company shall issue to Holder the number of shares of the Common Stock computed using the following formula:

X =	Y (A-B)
	A

Where: X =	the number of shares of Common Stock to be issued to Holder.
Y =	the number of shares of Common Stock purchasable under the amount of the Class B Warrant being exchanged (as adjusted to the date of such calculation).
A =	the Fair Market Value of one share of the Common Stock on the date that the notice of exercise is received by the Company.
B =	Exercise Price (as adjusted to the date of such calculation).

b) Exercise Price. The exercise price per share of the Common Stock under this Class B Warrant shall be nine ($0.09) cents, subject to adjustment hereunder (the “Exercise Price”).

c) Exercise Limitations. Holder shall not have the right to exercise any portion of this Class B Warrant, pursuant to Section 2 or otherwise, to the extent that after giving effect to such issuance after exercise, the Holder (together with the Holder’s affiliates, and any other person or entity acting as a group together with the Holder or any of the Holder’s affiliates), would beneficially own in excess of the Beneficial Ownership Limitation (as defined below). For purposes of this Section, beneficial ownership shall be calculated in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder. Holder is solely responsible for any schedules required to be filed in accordance therewith. The Company shall have no obligation to verify or confirm the accuracy of such filings. In any case, the number of outstanding shares of Common Stock shall be determined after giving effect to the conversion or exercise of securities of the Company, including this Class B Warrant, by the Holder or its affiliates since the date as of which such number of outstanding shares of Common Stock was reported. The “Beneficial Ownership Limitation” shall be 4.99% of the number of shares of the Common Stock outstanding immediately after giving effect to the issuance of Class B Warrant Shares issuable upon exercise of this Class B Warrant. The Holder, upon not less than 61 days’ prior notice to the Company, may increase or decrease the Beneficial Ownership Limitation provisions of this Section 2(c), provided that the Beneficial Ownership Limitation may not exceed 9.99% of the number of shares of the Common Stock outstanding immediately after giving effect to the issuance of Class B Warrant Shares upon exercise of this Class B Warrant held by the Holder and the provisions of this Section 2(c) shall continue to apply, unless the Holder upon not less than 61 days’ prior notice to the Company determines to waive the Beneficial Ownership Limitation requirements described in this Section 2(c) in its entirety. Any such increase or decrease will not be effective until the 61^st day after such notice is delivered to the Company. The limitations contained in this paragraph shall apply to a successor holder of this Class B Warrant.

d) Mechanics of Exercise.

i. Delivery of Certificates Upon Exercise. Certificates for shares purchased hereunder shall be transmitted by the Company’s transfer agent (the “Transfer Agent”) to the Holder by crediting the account of the Holder’s prime broker with the Depository Trust Company through its Deposit Withdrawal Agent Commission (“DWAC”) system if the Company is then a participant in such system and either (A) there is an effective registration statement permitting the resale of the Class B Warrant Shares by the Holder or (B) the shares are eligible for resale without volume or manner-of-sale limitations pursuant to Rule 144, and otherwise by physical delivery of certificates to the address specified by the Holder in the Notice of Exercise within four (4) Trading Days from the delivery to the Company of the Notice of Exercise Form, surrender of this Class B Warrant (if required) and payment of the aggregate Exercise Price as set forth above (the “Warrant Share Delivery Date”). This Class B Warrant shall be deemed to have been exercised on the date the Exercise Price is received by the Company. The Class B Warrant Shares shall be deemed to have been issued, and Holder or any other person so designated to be named therein shall be deemed to have become a holder of record of such shares for all purposes, as of the date the Class B Warrant has been exercised by payment to the Company of the Exercise Price and all taxes required to be paid by the Holder, if any, pursuant to Section 2(d)(vi) prior to the issuance of such shares, have been paid. If the Company is obligated to and fails for any reason to deliver to the Holder certificates evidencing the Class B Warrant Shares subject to a Notice of Exercise by the Class B Warrant Share Delivery Date, the Company shall pay to the Holder, in cash, as liquidated damages and not as a penalty, for each $1,000 of Class B Warrant Shares subject to such exercise, $10 per Trading Day (increasing to $20 per Trading Day on the seventh Trading Day after such liquidated damages begin to accrue) for each Trading Day after such Warrant Share Delivery Date until such certificates are delivered.

ii. Delivery of New Warrants Upon Exercise. If this Class B Warrant shall have been exercised in part, the Company shall, at the request of a Holder and upon surrender of this Class B Warrant certificate, at the time of delivery of the certificate or certificates representing Class B Warrant Shares, deliver to Holder a new Warrant evidencing the rights of Holder to purchase the unpurchased Class B Warrant Shares called for by this Class B Warrant, which new Warrant shall in all other respects be identical with this Class B Warrant.

iii. Rescission Rights. If the Company fails to cause the Transfer Agent to transmit to the Holder a certificate or the certificates representing the Class B Warrant Shares pursuant to Section 2(d)(i) by the Class B Warrant Share Delivery Date, then the Holder will have the right to rescind such exercise.

iv. Compensation for Buy-In on Failure to Timely Deliver Certificates Upon Exercise. In addition to any other rights available to the Holder, if the Company fails for any reason to deliver to the Holder such certificate or certificates by the Class B Warrant Share Delivery Date, and if after such Warrant Share Delivery Date the Holder is required by its brokerage firm to purchase (in an open market transaction or otherwise), or the Holder’s brokerage firm otherwise purchases, shares of Common Stock to deliver in satisfaction of a sale by the Holder of the Class B Warrant Shares which the Holder was entitled to receive upon the exercise relating to such Warrant Share Delivery Date (a “Buy-In”), then the Company shall (A) pay in cash to the Holder (in addition to any other remedies available to or elected by the Holder) the amount by which (x) the Holder’s total purchase price (including any brokerage commissions) for the Common Stock so purchased exceeds (y) the product of (1) the aggregate number of Class B Warrant Shares that the Company was required to deliver to the Holder in connection with the exercise at issue multiplied by (2) the price at which the sell order giving rise to such purchase obligation was executed (including any brokerage commissions) and (B) at the option of the Holder, either reinstate the portion of the Class B Warrant and equivalent number of Class B Warrant Shares for which such exercise was not honored (in which case such exercise shall be deemed rescinded) or deliver to the Holder the number of shares of Common Stock that would have been issued had the Company timely complied with its exercise and delivery obligations hereunder. For example, if the Holder purchases Common Stock having a total purchase price of $11,000 to cover a Buy-In with respect to an attempted exercise of this Class B Warrant with respect to which the sale price of the Class B Warrant Shares (including any brokerage commissions) giving rise to such purchase obligation was a total of $10,000 under clause (A) of the immediately preceding sentence, the Company shall be required to pay the Holder $1,000. The Holder shall provide the Company written notice indicating the amounts payable to the Holder in respect of the Buy-In and, upon request of the Company, evidence of the amount of such loss. Nothing herein shall limit a Xxxxxx’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 Class B Warrant Shares upon exercise of this Class B Warrant as required pursuant to the terms hereof.

v. No Fractional Shares or Scrip. No fractional shares or scrip representing fractional shares shall be issued upon the exercise of this Class B Warrant. As to any fraction of a share which Holder would otherwise be entitled to purchase upon such exercise, the Company shall, at its election, either pay a cash adjustment in respect of such final fraction in an amount equal to such fraction multiplied by the Exercise Price or round up to the next whole share.

vi. Charges, Taxes and Expenses. Issuance of certificates for Class B Warrant Shares shall be made without charge to the Holder for any issue or transfer tax or other incidental expense in respect of the issuance of such certificate, all of which taxes and expenses shall be paid by the Company, and such certificates shall be issued in the name of the Holder or in such name or names as may be directed by the Holder; provided, however, that in the event certificates for Class B Warrant Shares are to be issued in a name other than the name of the Holder, this Class B Warrant when surrendered for exercise shall be accompanied by the assignment form (“Assignment Form”) attached hereto as Exhibit B duly executed by the Holder and the Company may require, as a condition thereto, the payment of a sum sufficient to reimburse it for any transfer tax incidental thereto.

vii. Closing of Books. The Company will not close its shareholder books or records in any manner which prevents the timely exercise of this Class B Warrant, pursuant to the terms hereof.

Section 3. Intentionally Omitted.

Section 4. Certain Adjustments.

a) Stock Dividends and Splits. If the Company, at any time while this Class B Warrant is outstanding: (i) pays a stock dividend or otherwise make a distribution or distributions on shares of its Common Stock or any other equity or equity equivalent securities payable in shares of Common Stock (which, for avoidance of doubt, shall not include any Class B Warrant Shares issued by the Company upon exercise of this Class B Warrant), (ii) subdivides outstanding shares of Common Stock into a larger number of shares, (iii) combines (including by way of reverse stock split) outstanding shares of Common Stock into a smaller number of shares or (iv) issues by reclassification of shares of the Common Stock any shares of capital stock of the Company, then in each case the Exercise Price shall be multiplied by a fraction of which the numerator shall be the number of shares of Common Stock (excluding treasury shares, if any) outstanding immediately before such event and of which the denominator shall be the number of shares of Common Stock outstanding immediately after such event and the number of shares issuable upon exercise of this Class B Warrant shall be proportionately adjusted such that the aggregate Exercise Price of this Class B Warrant shall remain unchanged. Any adjustment made pursuant to this Section 3(a) shall become effective immediately after the record date for the determination of shareholders entitled to receive such dividend or distribution and shall become effective immediately after the effective date in the case of a subdivision, combination or re-classification.

b) Subsequent Rights Offerings. In addition to any adjustments pursuant to the other subsections of this Section 4, if at any time the Company grants, issues or sells any Common Stock Equivalents or rights to purchase stock, warrants, securities or other property pro rata to the record holders of any class of shares of Common Stock (the “Purchase Rights”), then the Holder will be entitled to acquire, upon the terms applicable to such Purchase Rights, the aggregate Purchase Rights which the Holder could have acquired if the Holder had held the number of shares of Common Stock acquirable upon complete exercise of this Class B Warrant (without regard to any limitations on exercise hereof, including without limitation, the Beneficial Ownership Limitation) immediately before the date on which a record is taken for the grant, issuance or sale of such Purchase Rights, or, if no such record is taken, the date as of which the record holders of shares of Common Stock are to be determined for the grant, issue or sale of such Purchase Rights (provided, however, to the extent that the Holder’s right to participate in any such Purchase Right would result in the Holder exceeding the Beneficial Ownership Limitation, then the Holder shall not be entitled to participate in such Purchase Right to such extent (or beneficial ownership of such shares of Common Stock as a result of such Purchase Right to such extent) and such Purchase Right to such extent shall be held in abeyance for the Holder until such time, if ever, as its right thereto would not result in the Holder exceeding the Beneficial Ownership Limitation).

c) Pro Rata Distributions. If the Company, at any time while this Class B Warrant is outstanding, shall distribute to all holders of Common Stock (and not to the Holder) evidences of its indebtedness or assets (including cash and cash dividends) or rights or warrants to subscribe for or purchase any security other than the Common Stock, then in each such case the Exercise Price shall be adjusted by multiplying the Exercise Price in effect immediately prior to the record date fixed for determination of stockholders entitled to receive such distribution by a fraction of which the denominator shall be the VWAP determined as of the record date mentioned above, and of which the numerator shall be such VWAP on such record date less than the per share fair market value at such record date of the portion of such assets or evidence of indebtedness or rights or warrants so distributed applicable to one outstanding share of the Common Stock as determined by the Board of Directors in good faith. In either case the adjustments shall be described in a statement provided to the Holder of the portion of assets or evidences of indebtedness so distributed or such subscription rights applicable to one share of Common Stock. Such adjustment shall be made whenever any such distribution is made and shall become effective immediately after the record date mentioned above.

d) Fundamental Transaction. If, at any time while this Class B Warrant is outstanding, (i) the Company effects any merger or consolidation of the Company with or into another Person, (ii) the Company effects any sale of all or substantially all of its assets in one or a series of related transactions, (iii) 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 (iv) 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 (each “Fundamental Transaction”), then, upon any subsequent exercise of this Class B Warrant, the Holder shall have the right to receive, for each Warrant Share that would have been issuable upon such exercise immediately prior to the occurrence of such Fundamental Transaction, the number of shares of Common Stock of the successor or acquiring corporation or of the Company, if it is the surviving corporation, and any additional consideration (the “Alternate Consideration”) receivable as a result of such Fundamental Transaction by a holder of the number of shares of Common Stock for which this Class B Warrant is exercisable immediately prior to such Fundamental Transaction. 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 Class B Warrant following such Fundamental Transaction. To the extent necessary to effectuate the foregoing provisions, any successor to the Company or surviving entity in such Fundamental Transaction shall issue to the Holder a new warrant consistent with the foregoing provisions and evidencing the Holder’s right to exercise such warrant into Alternate Consideration. 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 4(d) and insuring that this Class B Warrant (or any such replacement security) will be similarly adjusted upon any subsequent transaction analogous to a Fundamental Transaction. Notwithstanding anything to the contrary, in the event of a Fundamental Transaction that is (1) an all cash transaction, (2) a “Rule 13e-3 transaction” as defined in Rule 13e-3 under the Exchange Act, or (3) a Fundamental Transaction involving a person or entity not traded on a national securities exchange, the Company or any successor entity shall pay concurrently with the consummation of the Fundamental Transaction, and the Holder shall accept an amount of cash equal to the value of this Class B Warrant as determined in accordance with the Black Scholes Option Pricing Model obtained from the “OV” function on Bloomberg L.P. using (A) a price per share of Common Stock equal to the VWAP of the Common Stock for the Trading Day immediately preceding the date of consummation of the applicable Fundamental Transaction, (B) a risk-free interest rate corresponding to the U.S. Treasury rate for a 30 day period immediately prior to the consummation of the applicable Fundamental Transaction, (C) an expected volatility equal to the 100 day volatility obtained from the “HVT” function on Bloomberg L.P. determined as of the Trading Day immediately following the public announcement of the applicable Fundamental Transaction and (D) a remaining option time equal to the time between the date of the public announcement of such transaction and the Termination Date; provided that in each case where Bloomberg L.P. data is being relied upon, Holder shall provide to the Company a copy of such information for the Company's records.

e) Calculations. All calculations under this Section 4 shall be made to the nearest cent or the nearest 1/100th of a share, as the case may be. For purposes of this Section 4, the number of shares of Common Stock deemed to be issued and outstanding as of a given date shall be the sum of the number of shares of Common Stock (excluding treasury shares, if any) issued and outstanding.

f) Notice to Holder.

i. Adjustment to Exercise Price. Whenever the Exercise Price is adjusted pursuant to any provision of this Section 4, the Company shall promptly mail to the Holder a notice setting forth the Exercise Price after such adjustment and setting forth a brief statement of the facts requiring such adjustment.

ii. Notice to Allow Exercise by Xxxxxx. If (A) the Company shall declare a dividend (or any other distribution in whatever form) on the Common Stock, (B) the Company shall declare a special nonrecurring cash dividend on or a redemption of the Common Stock, (C) the Company shall authorize the granting to all holders of the Common Stock rights or warrants to subscribe for or purchase any shares of capital stock of any class or of any rights, (D) the approval of any shareholders of the Company shall be required in connection with any reclassification of the Common Stock, any consolidation or merger to which the Company is a party, any sale or transfer of all or substantially all of the assets of the Company, of any compulsory share exchange whereby the Common Stock is converted into other securities, cash or property, or (E) the Company shall authorize the voluntary or involuntary dissolution, liquidation or winding up of the affairs of the Company, then, in each case, the Company shall cause to be mailed to the Holder at its last address as it shall appear upon the Class B Warrant Register of the Company, at least 20 calendar days prior to the applicable record or effective date hereinafter specified, a notice stating (x) the date on which a record is to be taken for the purpose of such dividend, distribution, redemption, rights or warrants, or if a record is not to be taken, the date as of which the holders of the Common Stock of record to be entitled to such dividend, distributions, redemption, rights or warrants are to be determined or (y) the date on which such reclassification, consolidation, merger, sale, transfer or share exchange is expected to become effective or close, and the date as of which it is expected that holders of the Common Stock of record shall be entitled to exchange their shares of the Common Stock for securities, cash or other property deliverable upon such reclassification, consolidation, merger, sale, transfer or share exchange; provided that the failure to mail such notice or any defect therein or in the mailing thereof shall not affect the validity of the corporate action required to be specified in such notice. The Holder is entitled to exercise this Class B Warrant during the period commencing on the date of such notice to the effective date of the event triggering such notice.

Section 5. Transfer of Warrant.

a) Transferability. Subject to compliance with any applicable securities laws and the conditions set forth in Section 5(d) herein and to the provisions of the Subscription Agreement, this Class B Warrant and all rights hereunder (including, without limitation, any registration rights) are transferable, in whole or in part, upon surrender of this Class B Warrant at the principal office of the Company or its designated agent, together with a written assignment of this Class B Warrant substantially in the form attached hereto duly executed by the Holder or its agent or attorney and funds sufficient to pay any transfer taxes payable upon the making of such transfer. Upon such surrender and, if required, such payment, the Company shall execute and deliver a new Warrant or Warrants in the name of the assignee or assignees, as applicable, and in the denomination or denominations specified in such instrument of assignment, and shall issue to the assignor a new Warrant evidencing the portion of this Class B Warrant not so assigned, and this Class B Warrant shall promptly be cancelled. The Warrant, if properly assigned, may be exercised by a new holder for the purchase of Class B Warrant Shares without having a new Warrant issued.

b) New Class B Warrants. This Class B Warrant may be divided or combined with other Class B Warrants upon presentation hereof at the aforesaid office of the Company, together with a written notice specifying the names and denominations in which new Class B Warrants are to be issued, signed by the Holder or its agent or attorney. Subject to compliance with Section 5(a), as to any transfer which may be involved in such division or combination, the Company shall execute and deliver a new Class B Warrant or Class B Warrants in exchange for this Class B Warrant or Warrants to be divided or combined in accordance with such notice. All Class B Warrants issued on transfers or exchanges shall be dated the Initial Exercise Date and shall be identical with this Class B Warrant except as to the number of Class B Warrant Shares issuable pursuant thereto.

c) Class B Warrant Register. The Company shall register this Class B Warrant, upon records to be maintained by the Company for that purpose (the “Class B 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 Class B 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.

d) Transfer Restrictions. If, at the time of the surrender of this Class B Warrant in connection with any transfer of this Class B Warrant, the transfer of this Class B Warrant shall not be either (i) registered pursuant to an effective registration statement under the Securities Act and under applicable state securities or blue sky laws or (ii) eligible for resale without volume or manner-of-sale restrictions pursuant to Rule 144, the Company may require, as a condition of allowing such transfer, that the Holder or transferee of this Class B Warrant, as the case may be, comply with the provisions of the Subscription Agreement.

Section 6. Miscellaneous.

a) No Rights as Shareholder Until Exercise. This Class B Warrant does not entitle the Holder to any voting rights or other rights as a shareholder of the Company prior to the exercise hereof.

b) Loss, Theft, Destruction or Mutilation of Warrant. The Company covenants that upon receipt by the Company of evidence reasonably satisfactory to it of the loss, theft, destruction or mutilation of this Class B Warrant or any stock certificate relating to the Class B Warrant Shares, and in case of loss, theft or destruction, of indemnity or security reasonably satisfactory to it (which, in the case of the Class B Warrant, shall not include the posting of any bond), and upon surrender and cancellation of such Warrant or stock certificate, if mutilated, the Company will make and deliver a new Warrant or stock certificate of like tenor and dated as of such cancellation, in lieu of such Warrant or stock certificate.

c) Saturdays, Sundays, Holidays, etc. If the last or appointed day for the taking of any action or the expiration of any right required or granted herein shall not be a Business Day, then, such action may be taken or such right may be exercised on the next succeeding Business Day.

d) Authorized Shares.

Subject to Stockholder Approval (as such term is defined in the Subscription Agreement), the Company covenants that, during the period this Class B Warrant is outstanding, it will reserve from its authorized and unissued Common Stock one hundred (100%) of the number of shares to provide for the issuance of the Class B Warrant Shares upon the exercise of any purchase rights under this Class B Warrant. In case such amount of Common Stock is insufficient at any time, the Company shall call and hold a special meeting to increase the number of authorized shares of common stock. Management of the Company shall recommend to shareholders to vote in favor of increasing the number of authorized shares of common stock.

The Company further covenants that its issuance of this Class B Warrant shall constitute full authority to its officers who are charged with the duty of executing stock certificates to execute and issue the necessary certificates for the Class B Warrant Shares upon the exercise of the purchase rights under this Class B Warrant. The Company will take all such reasonable action as may be necessary to assure that such Class B Warrant Shares may be issued as provided herein without violation of any applicable law or regulation, or of any requirements of the Trading Market upon which the Common Stock may be listed. The Company covenants that all Class B Warrant Shares which may be issued upon the exercise of the purchase rights represented by this Class B Warrant will, upon exercise of the purchase rights represented by this Class B Warrant, be duly authorized, validly issued, fully paid and nonassessable and free from all taxes, liens and charges created by the Company in respect of the issue thereof (other than taxes in respect of any transfer occurring contemporaneously with such issue).

Except and to the extent as waived or consented to by the Holder, the Company shall not by any action, including, without limitation, amending its amended and restated certificate of incorporation, as amended, or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of this Class B Warrant, but will at all times in good faith assist in the carrying out of all such terms and in the taking of all such actions as may be necessary or appropriate to protect the rights of Holder as set forth in this Class B Warrant against impairment. Without limiting the generality of the foregoing, the Company will (i) not increase the par value of any Class B Warrant Shares above the amount payable therefor upon such exercise immediately prior to such increase in par value, (ii) take all such action as may be necessary or appropriate in order that the Company may validly and legally issue fully paid and nonassessable Class B Warrant Shares upon the exercise of this Class B Warrant and (iii) use commercially reasonable efforts to obtain all such authorizations, exemptions or consents from any public regulatory body having jurisdiction thereof, as may be, necessary to enable the Company to perform its obligations under this Class B Warrant.

Before taking any action which would result in an adjustment in the number of Class B Warrant Shares for which this Class B Warrant is exercisable or in the Exercise Price, the Company shall obtain all such authorizations or exemptions thereof, or consents thereto, as may be necessary from any public regulatory body or bodies having jurisdiction thereof.

e) Jurisdiction. All questions concerning the construction, validity, enforcement and interpretation of this Class B Warrant shall be determined in accordance with the provisions of the Subscription Agreement.

f) Restrictions. The Holder acknowledges that the Class B Warrant Shares acquired upon the exercise of this Class B Warrant, if not registered, will have restrictions upon resale imposed by state and federal securities laws.

g) Nonwaiver and Expenses. No course of dealing or any delay or failure to exercise any right hereunder on the part of Holder shall operate as a waiver of such right or otherwise prejudice Holder’s rights, powers or remedies, notwithstanding the fact that all rights hereunder terminate on the Termination Date. If the Company willfully and knowingly fails to comply with any provision of this Class B Warrant, which results in any material damages to the Holder, the Company shall pay to Holder such amounts as shall be sufficient to cover any costs and expenses including, but not limited to, reasonable attorneys’ fees, including those of appellate proceedings, incurred by Holder in collecting any amounts due pursuant hereto or in otherwise enforcing any of its rights, powers or remedies hereunder.

h) Notices. Any notice, request or other document required or permitted to be given or delivered to the Holder by the Company shall be delivered in accordance with the notice provisions of the Subscription Agreement.

i) Limitation of Liability. No provision hereof, in the absence of any affirmative action by Holder to exercise this Class B Warrant to purchase Class B Warrant Shares, and no enumeration herein of the rights or privileges of Holder, shall give rise to any liability of Holder for the purchase price of any Common Stock or as a shareholder of the Company, whether such liability is asserted by the Company or by creditors of the Company.

j) Remedies. The Holder, in addition to being entitled to exercise all rights granted by law, including recovery of damages, will be entitled to specific performance of its rights under this Class B Warrant. The Company agrees that monetary damages would not be adequate compensation for any loss incurred by reason of a breach by it of the provisions of this Class B Warrant and hereby agrees to waive and not to assert the defense in any action for specific performance that a remedy at law would be adequate.

k) Successors and Assigns. Subject to applicable securities laws, this Class B Warrant and the rights and obligations evidenced hereby shall inure to the benefit of and be binding upon the successors of the Company and the successors and permitted assigns of Holder. The provisions of this Class B Warrant are intended to be for the benefit of all Holders from time to time of this Class B Warrant and shall be enforceable by the Holder or holder of Class B Warrant Shares.

l) Amendment. This Class B Warrant may be modified or amended or the provisions hereof waived with the written consent of the Company and the Holder.

m) Severability. Wherever possible, each provision of this Class B Warrant shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Class B Warrant shall be prohibited by or invalid under applicable law, such provision shall be ineffective to the extent of such prohibition or invalidity, without invalidating the remainder of such provisions or the remaining provisions of this Class B Warrant.

n) Headings. The headings used in this Class B Warrant are for the convenience of reference only and shall not, for any purpose, be deemed a part of this Class B Warrant.
