(a) Exercise Period. The Holder may exercise this Warrant in whole or in part on any Business Day on or before 5:00 P.M., Eastern Time, on the Expiration Date, at which time this Warrant shall become void and of no value.

(b) Exercise Procedures.

(i) While this Warrant remains outstanding and exercisable in accordance with Section 1(a), the Holder may exercise this Warrant in whole or in part at any time and from time to time by:

(A) delivery to the Company of a duly completed and executed copy of the notice of exercise attached as Exhibit A (the “Notice of Exercise”);

(B) surrender of this Warrant to the Secretary of the Company at its principal offices or at such other office or agency as the Company may specify in writing to the Holder; and

(C) payment of the then-applicable Exercise Price per share multiplied by the number of Warrant Shares being purchased upon exercise of the Warrant (such amount, the “Aggregate Exercise Price”) made in the form of cash, or by certified check, wire transfer, bank draft or money order payable in lawful money of the United States of America.

(ii) Upon the exercise of this Warrant in compliance with the provisions of this Section 1(b), and except as limited pursuant to Section 1(b)(iii), the Company shall promptly issue and cause to be delivered to the Holder a certificate for the Warrant Shares purchased by the Holder. Each exercise of this Warrant shall be effective immediately prior to the close of business on the date (the “Date of Exercise”) that the conditions set forth in Section 1(b) have been satisfied, as the case may be. Upon delivery of each of the items set forth in Section 1(b)(i), the Holder shall be deemed for all corporate purposes to have become the holder of record of the Warrant Shares with respect to which this Warrant has been exercised, irrespective of the date of delivery of the certificates evidencing such Warrant Shares.

(iii) Notwithstanding the foregoing provisions of this Section 1(b), the Holder may not exercise this Warrant if and to the extent that such exercise would require the Company to issue a number of shares of Common Stock in excess of its authorized but unissued shares of Common Stock, less all amounts of Common Stock that have been reserved for issue upon the conversion of all outstanding securities convertible into shares of Common Stock and the exercise of all outstanding Options and other rights exercisable for shares of Common Stock. If the Company does not have the requisite number of authorized but unissued shares of Common Stock to permit the Holder to exercise this Warrant, then the Company shall use commercially reasonable efforts to obtain the necessary stockholder consent to increase the authorized number of shares of Common Stock to permit such Holder to exercise this Warrant pursuant to Section 1(b)(i).

(iv) Obligation Absolute. The Company’s obligations to issue and deliver the Warrant Shares upon exercise of this Warrant in accordance with the terms hereof are absolute and unconditional, irrespective of any action or inaction by the Holder to enforce the same, any waiver or consent with respect to any provision hereof, the recovery of any judgment against any Person or any action to enforce the same, or any setoff, counterclaim, recoupment, limitation or termination, or any breach or alleged breach by the Holder or any other Person of any obligation to the Company or any violation or alleged violation of law by the Holder or any other Person, and irrespective of any other circumstance which might otherwise limit such obligation of the Company to the Holder in connection with the issuance of such Warrant Shares; provided, however, that such delivery shall not operate as a waiver by the Company of any such action the Company may have against the Holder. The Company may not refuse exercise based on any claim that the Holder or anyone associated or affiliated with the Holder has been engaged in any violation of law, agreement or for any other reason, unless an injunction from a court, on notice to Holder, restraining and or enjoining exercise of all or part of this Warrant shall have been sought and obtained, and the Company posts a surety bond for the benefit of the Holder in the amount of 130% of the aggregate Exercise Price of all Warrant Shares issuable upon exercise of this Warrant, which is subject to the injunction, which bond shall remain in effect until the completion of arbitration/litigation of the underlying dispute and the proceeds of which shall be payable to the Holder to the extent it obtains judgment. In the absence of such injunction, the Company shall issue Warrant Shares.

(v) Certain Mechanics of Exercise. Notwithstanding the foregoing provisions of this Section 1(b), if on the Date of Exercise the Common Stock is listed on a national or regional stock exchange or quoted on the OTC Markets, and (a) this Warrant is exercised for cash and there is then an effective registration statement registering the sale of the Warrant Shares by the Holder, or (b) this Warrant is exercised on a cashless basis pursuant to subsection (vi) below and the Warrant Shares are eligible for sale by the Holder pursuant to Rule 144 promulgated under the Securities Act, the following provisions shall apply:

(A) Delivery of Certificate upon Exercise. Not later than five (5) Trading Days (as defined below) after the Date of Exercise (the “Share Delivery Date”), the Company shall deliver, or cause to be delivered, to the Holder a certificate or certificates representing the Warrant Shares which shall be free of restrictive legends and trading restrictions, representing the number of Warrant Shares being acquired upon the exercise of this Warrant. The Company shall use its best efforts to deliver any certificate or certificates required to be delivered by the Company under this Section electronically through the Depository Trust Company or another established clearing corporation performing similar functions.

(B) Partial Liquidated Damages. If the Company fails for any reason to deliver to the Holder such certificate or certificates pursuant to Section 1(b)(v)(A) by the 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 principal amount being converted, $10 per Trading Day (increasing to $20 per Trading Day on the seventh (7th) Trading Day after such liquidated damages begin to accrue) for each Trading Day after such Share Delivery Date until such certificates are delivered. Nothing herein shall limit a Holder’s right to pursue actual damages for the Company’s failure to deliver Warrant Shares within the period specified herein and the Holder shall have the right to pursue all remedies available to it hereunder, at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief. The exercise of any such rights shall not prohibit the Holder from seeking to enforce damages pursuant to any other Section hereof or under applicable law.

(C) 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 Share Delivery Date, and if after such Share Delivery Date the Holder purchases or 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 Warrant Shares which the Holder was entitled to receive upon the exercise relating to such 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), if any, 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 shares of Common Stock that the Holder was entitled to receive from the exercise at issue multiplied by (2) the actual per share sale 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 reissue (if surrendered) this Warrant in a principal amount equal to the principal amount of the attempted exercise (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 if the Company had timely complied with its delivery requirements under Section 4(d)(ii). 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 Warrant with respect to which the actual sale price of the 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 Holder’s right to pursue any other remedies available to it hereunder, at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief with respect to the Company’s failure to timely deliver certificates representing shares of Common Stock upon exercise of this Warrant as required pursuant to the terms hereof.

(vi) Cashless Exercise. If at any time after the Registration Effectiveness Date (as defined in the Registration Rights Agreement) there is no effective registration statement registering, or the prospectus contained therein is not available for the resale of the Warrant Shares by the Holder, then this Warrant may also be exercised, in whole or in part, at such time by means of a “cashless exercise” in which the Holder shall be entitled to receive a number of Warrant Shares equal to the quotient obtained by dividing [(A-B) (X)] by (A), where:

“Bid Price” means, for any date, the price determined by the first of the following clauses that applies: (a) if the Common Stock are then listed or quoted on a Trading Market, the bid price of the Common Stock for the time in question (or the nearest preceding date) on the Trading Market on which the Common Stock are then listed or quoted as reported by Bloomberg (based on a Trading Day from 9:30 a.m. (New York City time) to 4:02 p.m. (New York City time)), (b) if OTCQB or OTCQX is not a Trading Market, the volume weighted average price of the Common Stock for such date (or the nearest preceding date) on OTCQB or OTCQX as applicable, (c) if the Common Stock are not then listed or quoted for trading on OTCQB or OTCQX and if prices for the Common Stock are then reported on The Pink Open Market (or a similar organization or agency succeeding to its functions of reporting prices), the most recent bid price per share of Common Stock so reported, or (d) in all other cases, the fair market value of a share of Common Stock as determined by an independent appraiser selected in good faith by the Holders of a majority in interest of the Warrants then outstanding and reasonably acceptable to the Company, the fees and expenses of which shall be paid by the Company.

“VWAP” means, for any date, the price determined by the first of the following clauses that applies: (a) if the Common Stock are then listed or quoted on a Trading Market, the daily volume weighted average price of the Common Stock for such date (or the nearest preceding date) on the Trading Market on which the Common Stock are then listed or quoted as reported by Bloomberg (based on a Trading Day from 9:30 a.m. (New York City time) to 4:02 p.m. (New York City time)), (b) if OTCQB or OTCQX is not a Trading Market, the volume weighted average price of the Common Stock for such date (or the nearest preceding date) on OTCQB or OTCQX as applicable, (c) if the Common Stock are not then listed or quoted for trading on OTCQB or OTCQX and if prices for the Common Stock are then reported on The Pink Open Market (or a similar organization or agency succeeding to its functions of reporting prices), the most recent bid price per share of Common Stock so reported, or (d) in all other cases, the fair market value of a share of Common Stock as determined by an independent appraiser selected in good faith by the Holders of a majority in interest of the Warrants then outstanding and reasonably acceptable to the Company, the fees and expenses of which shall be paid by the Company.

If Warrant Shares are issued in such a cashless exercise, the parties acknowledge and agree that in accordance with Section 3(a)(9) of the Securities Act, the Warrant Shares shall take on the characteristics of the Warrants being exercised, and the holding period of the Warrant Shares being issued may be tacked on to the holding period of this Warrant. Assuming (i) the Holder is not an Affiliate of the Company, and (ii) all of the applicable conditions of Rule 144 promulgated under the Securities Act with respect to Holder and the Warrant Shares are met in the case of such a cashless exercise, the Company agrees that the Company will cause the removal of the legend from such Warrant Shares (including by delivering an opinion of the Company’s counsel to the Company’s transfer agent at its own expense to ensure the foregoing), and the Company agrees that the Holder is under no obligation to sell the Warrant Shares issuable upon the exercise of the Warrant prior to removing the legend. The Company agrees not to take any position contrary to this Section 1(b)(vi).

Notwithstanding anything herein to the contrary, in the event that, on the Expiration Date, there is no effective registration statement registering, or no current prospectus available for the issuance of, the Warrant Shares to the Holder, this Warrant shall be automatically exercised via cashless exercise pursuant to this Section 1(b)(vi) on such Expiration Date.

(c) Partial Exercise. This Warrant shall be exercisable, either in its entirety or, from time to time, for part only of the number of Warrant Shares referenced by this Warrant; provided, that any such partial exercise must be for an integral number of Warrant Shares. If this Warrant is exercised in part, the Company shall issue, at its expense, a new Warrant, in substantially the form of this Warrant, referencing such reduced number of Warrant Shares that remain subject to this Warrant.

(d) Maximum Exercise. Notwithstanding anything to the contrary contained in this Warrant, this Warrant shall not be exercisable by the Holder hereof to the extent (but only to the extent) that such exercise would cause the Holder and its affiliates (if they are not, prior to such exercise, already beneficial owners of greater than 9.99% (the “Maximum Percentage”) of the Company’s outstanding Common Stock) to beneficially own in excess of the Maximum Percentage of the Company’s outstanding Common Stock; provided, however, that the Holder may reduce the Maximum Percentage or waive the limitation imposed by this subsection, and/or increase the Maximum Percentage to some other amount, upon at least sixty-one (61) days written notice to the Company prior to the Date of Exercise. For the purposes of this Section, beneficial ownership and all determinations and calculations (including, without limitation, with respect to calculations of percentage ownership) shall be determined in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder. The limitations contained in this paragraph shall apply to a successor Holder of this Warrant.

(e) Disputes. In the case of a dispute as to the determination of the Exercise Price or the arithmetic calculation of the Warrant Shares, the Company shall promptly issue to the Holder the number of Warrant Shares that are not disputed and resolve such dispute in accordance with Section 15.

(a) The Company covenants that all Warrant Shares will, upon issuance in accordance with the terms of this Warrant, be (i) duly authorized, fully paid and non-assessable, and (ii) free from all liens, charges and security interests, with the exception of claims arising through the acts or omissions of any Holder and except as arising from applicable Federal and state securities laws.

(b) The Company shall register this Warrant upon records to be maintained by the Company for that purpose in the name of the record holder of such Warrant from time to time. The Company may deem and treat the registered Holder of this Warrant as the absolute owner thereof for the purpose of any exercise thereof, any distribution to the Holder thereof and for all other purposes.

(c) The Company will not, by amendment of its articles of incorporation, by-laws 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 to be observed or performed hereunder by the Company, but will at all times in good faith assist in the carrying out of all the provisions of this Warrant and in the taking of all action necessary or appropriate in order to protect the rights of the Holder to exercise this Warrant, or against impairment of such rights.

(a) The Exercise Price and the number of shares purchasable upon the exercise of this Warrant shall be subject to adjustment from time to time upon the occurrence of certain events described in this Section 3(a); provided, that notwithstanding the provisions of this Section 3, the Company shall not be required to make any adjustment if and to the extent that such adjustment would require the Company to issue a number of shares of Common Stock in excess of its authorized but unissued shares of Common Stock, less all amounts of Common Stock that have been reserved for issue upon the conversion of all outstanding securities convertible into shares of Common Stock and the exercise of all outstanding options, warrants and other rights exercisable for shares of Common Stock. If the Company does not have the requisite number of authorized but unissued shares of Common Stock to make any adjustment, the Company shall use its commercially reasonable efforts to obtain the necessary stockholder consent to increase the authorized number of shares of Common Stock to make such an adjustment pursuant to this Section 3(a). Notwithstanding anything herein to the contrary, in no event will the Exercise Price per Warrant Share be reduced to less than the then-applicable par value per share of Common Stock.

(i) Subdivision or Combination of Stock. In case the Company shall at any time subdivide (whether by way of stock dividend, stock split or otherwise) 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 reduced and the number of Warrant Shares shall be proportionately increased, and conversely, in case the outstanding shares of Common Stock of the Company shall be combined (whether by way of stock combination, reverse stock split or otherwise) into a smaller number of shares, the Exercise Price in effect immediately prior to such combination shall be proportionately increased and the number of Warrant Shares shall be proportionately decreased. The Exercise Price and the Warrant Shares, as so adjusted, shall be readjusted in the same manner upon the happening of any successive event or events described in this Section 3(a)(i).

(ii) Dividends in Stock, Property, Reclassification. If at any time, or from time to time, the holders of Common Stock (or any shares of stock or other securities at the time receivable upon the exercise of this Warrant) shall have received or become entitled to receive, without payment therefor:

(A) any shares of stock or other securities that are at any time directly or indirectly convertible into or exchangeable for Common Stock, or any rights or options to subscribe for, purchase or otherwise acquire any of the foregoing by way of dividend or other distribution, or

(B) additional stock or other securities or property (including cash) by way of spin-off, split-up, reclassification, combination of shares or similar corporate rearrangement (other than shares of Common Stock issued as a stock split or adjustments in respect of which shall be covered by the terms of Section 3(a)(i) above),

then and in each such case, the Exercise Price and the number of Warrant Shares to be obtained upon exercise of this Warrant shall be adjusted proportionately, and the Holder hereof shall, upon the exercise of this Warrant, be entitled to receive, in addition to the number of shares of Common Stock receivable thereupon, and without payment of any additional consideration therefor, the amount of stock and other securities and property (including cash in the cases referred to above) that such Holder would hold on the date of such exercise had such Holder been the holder of record of such Common Stock as of the date on which holders of Common Stock received or became entitled to receive such shares or all other additional stock and other securities and property. The Exercise Price and the Warrant Shares, as so adjusted, shall be readjusted in the same manner upon the happening of any successive event or events described in this Section 3(a)(ii).

(iii) Reorganization, Reclassification, Consolidation, Merger or Sale. If any recapitalization, reclassification or reorganization of the capital stock of the Company, or any consolidation or merger of the Company with another corporation, or the sale of all or substantially all of its assets or other transaction shall be effected in such a way that holders of Common Stock shall be entitled to receive stock, securities or other assets or property (an “Organic Change”), then lawful and adequate provisions shall be made by the Company whereby the Holder hereof shall thereafter have the right to purchase and receive (in lieu of the shares of the Common Stock of the Company immediately theretofore purchasable and receivable upon the exercise of the rights represented by this Warrant) such shares of stock, securities or other assets or property as may be issued or payable with respect to or in exchange for a number of outstanding shares of such Common Stock equal to the number of shares of such stock immediately theretofore purchasable and receivable assuming the full exercise of the rights represented by this Warrant. In the event of any Organic Change, appropriate provision shall be made by the Company with respect to the rights and interests of the Holder of this Warrant to the end that the provisions hereof (including, without limitation, provisions for adjustments of the Exercise Price and of the number of shares purchasable and receivable upon the exercise of this Warrant) shall thereafter be applicable, in relation to any shares of stock, securities or assets thereafter deliverable upon the exercise hereof. To the extent necessary to effect the foregoing provisions, the successor corporation (if other than the Company) resulting from such consolidation or merger or the corporation purchasing such assets shall assume by written instrument reasonably satisfactory in form and substance to the Holder executed and mailed or delivered to the registered Holder hereof at the last address of such Holder appearing on the books of the Company, the obligation to deliver to such Holder such shares of stock, securities or assets as, in accordance with the foregoing provisions, such Holder may be entitled to purchase. If there is an Organic Change, then the Company shall cause to be mailed to the Holder at its last address as it shall appear on the books and records of the Company, at least ten (10) calendar days before the effective date of the Organic Change, a notice stating the date on which such Organic Change 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 for securities, cash, or other property delivered upon such Organic Change; 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 Warrant during the ten (10)-day period commencing on the date of such notice to the effective date of the event triggering such notice. In any event, the successor corporation (if other than the Company) resulting from such consolidation or merger or the corporation purchasing such assets shall be deemed to assume such obligation to deliver to such Holder such shares of stock, securities or assets even in the absence of a written instrument assuming such obligation to the extent such assumption occurs by operation of law. Notwithstanding the foregoing, in the event of an Organic Change where the consideration payable to holders of shares of Common Stock consists solely of cash, solely of marketable securities or a combination of cash and marketable securities, then this Warrant shall automatically be deemed to be exercised in full in a “cashless exercise” pursuant to Section 1(b)(iv) above effective immediately prior to and contingent upon the consummation of such Organic Change.

(b) Adjustment of Exercise Price upon Issuance of Additional Shares of Common Stock.

(i) Except as provided in Section 3(b)(iii) and except in the case of an event described in either Section 3(a)(i), Section 3(a)(ii), or Section 3(a)(iii), if the Company shall, at any time or from time to time after the Effective Date and before the date that is six (6) months after the date (if any) on which the Common Stock is listed for trading on the New York Stock Exchange, NYSE American or The Nasdaq Stock Market LLC (or any successor of each), issue or sell, or in accordance with Section 3(b)(iv) is deemed to have issued or sold, any Additional Shares of Common Stock without consideration or for consideration per share less than the Exercise Price in effect immediately prior to such issuance or sale (or deemed issuance or sale), then immediately upon such issuance or sale (or deemed issuance or sale), the Exercise Price in effect immediately prior to such issuance or sale (or deemed issuance or sale) shall be reduced (and in no event increased) to an Exercise Price (rounded to the nearest cent) equal to the quotient obtained by dividing:

(A) the sum of (A) the product obtained by multiplying the Common Stock Deemed Outstanding immediately prior to such issuance or sale (or deemed issuance or sale) by the Exercise Price then in effect plus (B) the aggregate consideration, if any, received by the Company upon such issuance or sale (or deemed issuance or sale); by

(B) the sum of (A) the Common Stock Deemed Outstanding immediately prior to such issuance or sale (or deemed issuance or sale) plus (B) the aggregate number of shares of Common Stock issued or sold (or deemed issued or sold) by the Company in such issuance or sale (or deemed issuance or sale).

(ii) Exceptions To Adjustment Upon Issuance of Common Stock. Anything herein to the contrary notwithstanding, there shall be no adjustment to the Exercise Price with respect to any Exempted Securities.

(iii) Effect of Certain Events on Adjustment to Exercise Price. For purposes of determining the adjusted Exercise Price under Section 3(b)(i) hereof, the following shall be applicable:

(A) Issuance of Options. If the Company shall, at any time or from time to time after the Effective Date, in any manner grant or sell any Options, whether or not such Options or the right to convert or exchange any Convertible Securities issuable upon the exercise of such Options are immediately exercisable, and the price per share (determined as provided in this paragraph and in Section 3(b)(iv)) for which Common Stock is issuable upon the exercise of such Options or upon the conversion or exchange of Convertible Securities issuable upon the exercise of such Options is less than the Exercise Price in effect immediately prior to the time of the granting or sale of such Options, then the total maximum number of shares of Common Stock issuable upon the exercise of such Options or upon conversion or exchange of the total maximum amount of Convertible Securities issuable upon the exercise of such Options shall be deemed to have been issued as of the date of granting or sale of such Options (and thereafter shall be deemed to be outstanding for purposes of adjusting the Exercise Price under Section 3(b)(i)), at a price per share equal to the quotient obtained by dividing (A) the sum (which sum shall constitute the applicable consideration received for purposes of Section 3(b)(i)) of (x) the total amount, if any, received or receivable by the Company as consideration for the granting or sale of all such Options, plus (y) the minimum aggregate amount of additional consideration payable to the Company upon the exercise of all such Options, plus (z) in the case of such Options which relate to Convertible Securities, the minimum aggregate amount of additional consideration, if any, payable to the Company upon the issuance or sale of all such Convertible Securities and the conversion or exchange of all such Convertible Securities, by (B) the total maximum number of shares of Common Stock issuable upon the exercise of all such Options or upon the conversion or exchange of all Convertible Securities issuable upon the exercise of all such Options. Except as otherwise provided in Section 3(b)(iv)(C), no further adjustment of the Exercise Price shall be made upon the actual issuance of Common Stock or of Convertible Securities upon exercise of such Options or upon the actual issuance of Common Stock upon conversion or exchange of Convertible Securities issuable upon exercise of such Options.

(B) Issuance of Convertible Securities. If the Company shall, at any time or from time to time after the Effective Date, in any manner grant or sell any Convertible Securities, whether or not the right to convert or exchange any such Convertible Securities is immediately exercisable, and the price per share (determined as provided in this paragraph and in Section 3(b)(iv)(E)) for which Common Stock is issuable upon the conversion or exchange of such Convertible Securities is less than the Exercise Price in effect immediately prior to the time of the granting or sale of such Convertible Securities, then the total maximum number of shares of Common Stock issuable upon conversion or exchange of the total maximum amount of such Convertible Securities shall be deemed to have been issued as of the date of granting or sale of such Convertible Securities (and thereafter shall be deemed to be outstanding for purposes of adjusting the Exercise Price pursuant to Section 3(b)(i)), at a price per share equal to the quotient obtained by dividing (A) the sum (which sum shall constitute the applicable consideration received for purposes of Section 3(b)(i)) of (x) the total amount, if any, received or receivable by the Company as consideration for the granting or sale of such Convertible Securities, plus (y) the minimum aggregate amount of additional consideration, if any, payable to the Company upon the conversion or exchange of all such Convertible Securities, by (B) the total maximum number of shares of Common Stock issuable upon the conversion or exchange of all such Convertible Securities. Except as otherwise provided in Section 3(b)(iv)(C), no further adjustment of the Exercise Price shall be made upon the actual issuance of Common Stock upon conversion or exchange of such Convertible Securities or the issue or sale of Convertible Securities upon exercise of any Options to purchase any such Convertible Securities for which adjustments of the Exercise Price have been made pursuant to the other provisions of this Section 3(b)(iv).

(C) Change in Terms of Options or Convertible Securities. Upon any change in any of (A) the total amount received or receivable by the Company as consideration for the granting or sale of any Options or Convertible Securities referred to in Section 3(b)(iv)(A) or Section 3(b)(iv)(B) hereof, (B) the minimum aggregate amount of additional consideration, if any, payable to the Company upon the exercise of any Options or upon the issuance, conversion or exchange of any Convertible Securities referred to in Section 3(b)(iv)(A) or Section 3(b)(iv)(B) hereof, (C) the rate at which Convertible Securities referred to in Section 3(b)(iv)(A) or Section 3(b)(iv)(B) hereof are convertible into or exchangeable for Common Stock, or (D) the maximum number of shares of Common Stock issuable in connection with any Options referred to in Section 3(b)(iv)(A) hereof or any Convertible Securities referred to in Section 3(b)(iv)(B) hereof (in each case, other than in connection with an Exempted Security), then (whether or not the original issuance or sale of such Options or Convertible Securities resulted in an adjustment to the Exercise Price pursuant to this Section 3(b)) the Exercise Price in effect at the time of such change shall be adjusted or readjusted, as applicable, to the Exercise Price which would have been in effect at such time pursuant to the provisions of this Section 3(b) had such Options or Convertible Securities still outstanding provided for such changed consideration, conversion rate, or maximum number of shares, as the case may be, at the time initially granted, issued, or sold, but only if as a result of such adjustment or readjustment the Exercise Price then in effect is reduced, and the number of Warrant Shares issuable upon the exercise of this Warrant immediately prior to any such adjustment or readjustment shall be correspondingly adjusted or readjusted pursuant to the provisions of Section 3(b)(ii).

(D) Treatment of Expired or Terminated Options or Convertible Securities. Upon the expiration or termination of any unexercised Option (or portion thereof) or any unconverted or unexchanged Convertible Security (or portion thereof) for which any adjustment (either upon its original issuance or upon a revision of its terms) was made pursuant to this Section 3(b) (including upon the redemption or purchase for consideration of all or any portion of such Option or Convertible Security by the Company), the Exercise Price then in effect hereunder shall forthwith be changed pursuant to the provisions of this Section 3(b) to the Exercise Price which would have been in effect at the time of such expiration or termination had such unexercised Option (or portion thereof) or unconverted or unexchanged Convertible Security (or portion thereof), to the extent outstanding immediately prior to such expiration or termination, never been issued.

(E) Calculation of Consideration Received. If the Company shall, at any time or from time to time after the Effective Date, issue or sell, or is deemed to have issued or sold in accordance with Section 3(b)(iv), any shares of Common Stock, Options, or Convertible Securities: (1) for cash, the consideration received therefor shall be deemed to be the net amount received by the Company therefor; (2) for consideration other than cash, the amount of the consideration other than cash received by the Company shall be the fair value of such consideration, except where such consideration consists of marketable securities, in which case the amount of consideration received by the Company shall be the market price (as reflected on any securities exchange, quotation system or association, or similar pricing system covering such security) for such securities as of the end of business on the date of receipt of such securities; (3) for no specifically allocated consideration in connection with an issuance or sale of other securities of the Company, together comprising one integrated transaction, the amount of the consideration therefor shall be deemed to be the fair value of such portion of the aggregate consideration received by the Company in such transaction as is attributable to such shares of Common Stock, Options, or Convertible Securities, as the case may be, issued in such transaction; or (4) to the owners of the non-surviving entity in connection with any merger in which the Company is the surviving corporation, the amount of consideration therefor shall be deemed to be the fair value of such portion of the net assets and business of the non-surviving entity as is attributable to such shares of Common Stock, Options, or Convertible Securities, as the case may be, issued to such owners. The net amount of any cash consideration and the fair value of any consideration other than cash or marketable securities shall be determined in good faith by the Board.

(F) Record Date. For purposes of any adjustment to the Exercise Price or the number of Warrant Shares in accordance with this Section 3(b), in case the Company shall take a record of the holders of its Common Stock for the purpose of entitling them (1) to receive a dividend or other distribution payable in Common Stock, Options, or Convertible Securities or (2) to subscribe for or purchase Common Stock, Options, or Convertible Securities, then such record date shall be deemed to be the date of the issue or sale of the shares of Common Stock deemed to have been issued or sold upon the declaration of such dividend or the making of such other distribution or the date of the granting of such right of subscription or purchase, as the case may be; provided, that if before the distribution to its holders of Common Stock the Company legally abandons its plan to pay or deliver such dividend, distribution, subscription, or purchase rights, then thereafter no adjustment shall be required by the taking of such record and any such adjustment previously made in respect thereof shall be rescinded and annulled.

(G) Treasury Shares. The number of shares of Common Stock outstanding at any given time shall not include shares owned or held by or for the account of the Company or any of its wholly-owned subsidiaries, and the disposition of any such shares (other than the cancellation or retirement thereof or the transfer of such shares among the Company and its wholly-owned subsidiaries) shall be considered an issue or sale of Common Stock for the purpose of this Section 3(b).

(c) Certificate as to Adjustments. Upon the occurrence of each adjustment or readjustment pursuant to this Section 3, the Company at its expense shall promptly compute such adjustment or readjustment in accordance with the terms hereof and furnish to each Holder of this Warrant a certificate setting forth such adjustment or readjustment and showing in detail the facts upon which such adjustment or readjustment is based. The Company shall promptly furnish or cause to be furnished to such Holder a like certificate setting forth: (i) such adjustments and readjustments; and (ii) the number of shares and the amount, if any, of other property which at the time would be received upon the exercise of the Warrant.

(d) Certain Events. If any event occurs as to which the other provisions of this Section 3 are not strictly applicable but the lack of any adjustment would not fairly protect the purchase rights of the Holder under this Warrant in accordance with the basic intent and principles of such provisions, or if strictly applicable would not fairly protect the purchase rights of the Holder under this Warrant in accordance with the basic intent and principles of such provisions, then the ’ Board will, in good faith and subject to applicable law, make an appropriate adjustment to protect the rights of the Holder; provided, that no such adjustment pursuant to this Section 3(d) will increase the Exercise Price as otherwise determined pursuant to this Section 3.

(a) Registration of Transfers and Exchanges. Subject to Section 4(c), upon the Holder’s surrender of this Warrant, with a duly executed copy of the Form of Assignment attached as Exhibit B, to the Secretary of the Company at its principal offices or at such other office or agency as the Company may specify in writing to the Holder, the Company shall register the transfer of all or any portion of this Warrant. Upon such registration of transfer, the Company shall issue a new Warrant, in substantially the form of this Warrant, evidencing the acquisition rights transferred to the transferee and a new Warrant, in similar form, evidencing the remaining acquisition rights not transferred, to the Holder requesting the transfer.

(b) Warrant Exchangeable for Different Denominations. The Holder may exchange this Warrant for a new Warrant or Warrants, in substantially the form of this Warrant, evidencing in the aggregate the right to purchase the number of Warrant Shares, which may then be purchased hereunder, each of such new Warrants to be dated the date of such exchange and to represent the right to purchase such number of Warrant Shares as shall be designated by the Holder. The Holder shall surrender this Warrant with duly executed instructions regarding such re-certification of this Warrant to the Secretary of the Company at its principal offices or at such other office or agency as the Company may specify in writing to the Holder.

(c) Restrictions on Transfers. This Warrant may not be transferred at any time without (i) registration under the Securities Act or (ii) an exemption from such registration and a written opinion of legal counsel addressed to the Company that the proposed transfer of the Warrant may be effected without registration under the Securities Act, which opinion will be in form and from counsel reasonably satisfactory to the Company.

(d) Permitted Transfers and Assignments. Notwithstanding any provision to the contrary in this Section 4, the Holder may transfer, with or without consideration, this Warrant or any of the Warrant Shares (or a portion thereof) to the Holder’s Affiliates (as such term is defined under Rule 144 of the Securities Act) without obtaining the opinion from counsel that may be required by Section 4(c)(ii), provided that the Holder delivers to the Company and its counsel certification, documentation, and other assurances reasonably required by the Company’s counsel to enable the Company’s counsel to render an opinion to the Company or its Transfer Agent that such transfer does not violate applicable securities laws.

If this Warrant is mutilated, lost, stolen or destroyed, upon request by the Holder, the Company will, at its expense, issue, in exchange for and upon cancellation of the mutilated Warrant, or in substitution for the lost, stolen or destroyed Warrant, a new Warrant, in substantially the form of this Warrant, representing the right to acquire the equivalent number of Warrant Shares; provided, that, as a prerequisite to the issuance of a substitute Warrant, the Company may require satisfactory evidence of loss, theft or destruction as well as an indemnity from the Holder of a lost, stolen or destroyed Warrant.

The Company will pay all transfer and stock issuance taxes attributable to the preparation, issuance and delivery of this Warrant and the Warrant Shares (and replacement Warrants) including, without limitation, all documentary and stamp taxes; provided, however, that the Company shall not be required to pay any tax in respect of the transfer of this Warrant, or the issuance or delivery of certificates for Warrant Shares or other securities in respect of the Warrant Shares to any Person or entity other than to the Holder. The Company shall pay all transfer agent fees required for processing of any exercise and any fees to the Depository Trust Company (or another established clearing corporation performing similar functions) required for electronic delivery of the Warrant Shares.

No fractional Warrant Shares shall be issued upon exercise of this Warrant. Upon the full exercise of this Warrant, the Company, in lieu of issuing any fractional Warrant Share, shall pay to the Holder an amount equal to the product obtained by multiplying the Exercise Price then in effect by the fraction of a share not issued pursuant to the previous sentence.

No holder of this Warrant, as such, shall be entitled to vote or be deemed the holder of any other securities of the Company that may at any time be issuable on the exercise hereof, nor shall anything contained herein be construed to confer upon the holder of this Warrant, as such, the rights of a stockholder of the Company or the right to vote for the election of directors or upon any matter submitted to stockholders at any meeting thereof, or give or withhold consent to any corporate action or to receive notice of meetings or other actions affecting stockholders (except as provided herein), or to receive dividends or subscription rights or otherwise (except as provide herein). Without limiting any rights of a Holder to receive Warrant Shares on a “cashless exercise” pursuant to Section 1(b)(vi), in no event shall the Company be required to net cash settle an exercise of this Warrant.

Each certificate for Warrant Shares initially issued upon the exercise of this Warrant, and each certificate for Warrant Shares issued to any subsequent transferee of any such certificate, shall be stamped or otherwise imprinted with a legend in substantially the following form:

NEITHER THE SECURITIES REPRESENTED HEREBY NOR THE SECURITIES ISSUABLE UPON THE EXERCISE OF THIS WARRANT HAVE BEEN REGISTERED UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”) OR ANY STATE SECURITIES LAWS. SUCH SECURITIES MAY BE OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED ONLY (A) TO THE COMPANY, (B) IN COMPLIANCE WITH RULE 144 UNDER THE SECURITIES ACT, IF AVAILABLE, AND IN ACCORDANCE WITH APPLICABLE STATE SECURITIES LAWS, (C) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT, OR (D) IN A TRANSACTION THAT DOES NOT REQUIRE REGISTRATION UNDER THE SECURITIES ACT OR ANY APPLICABLE STATE SECURITIES LAWS, AND THE HOLDER HAS, PRIOR TO SUCH SALE, FURNISHED TO THE COMPANY AN OPINION OF COUNSEL OR OTHER EVIDENCE OF EXEMPTION, IN EITHER CASE REASONABLY SATISFACTORY TO THE COMPANY. HEDGING TRANSACTIONS INVOLVING THESE SECURITIES MAY NOT BE CONDUCTED UNLESS IN COMPLIANCE WITH THE SECURITIES ACT.

The Holder shall be entitled to the registration rights with respect to the Warrant Shares set forth in, and subject to the conditions of, the Registration Rights Agreement.

All notices, consents, waivers, and other communications under this Warrant must be in writing and will be deemed given to a party when (a) delivered to the appropriate address by hand or by nationally recognized overnight courier service (costs prepaid); (b) sent by e-mail; (c) received or rejected by the addressee, if sent by certified mail, return receipt requested, if to the registered Holder hereof; or (d) seven days after the placement of the notice into the mails (first class postage prepaid), to the Holder at the address, facsimile number, or e- mail address furnished by the registered Holder to the Company in accordance with the Subscription Agreement by and between the Company and the Holder or, if the registered Holder is not the original purchaser of this Warrant, then as provided in the Form of Assignment delivered to the Company pursuant to Section 4(a) in connection with the assignment of this Warrant to such Holder, or if to the Company, to it at:

If a court of competent jurisdiction holds any provision of this Warrant invalid or unenforceable, the other provisions of this Warrant will remain in full force and effect. Any provision of this Warrant held invalid or unenforceable only in part or degree will remain in full force and effect to the extent not held invalid or unenforceable.

This Warrant shall be binding upon and inure to the sole and exclusive benefit of the Company, its successors and assigns, the registered Holder or Holders from time to time of this Warrant and the Warrant Shares.

This Warrant shall terminate and be of no further force and effect on the earlier of 5:00 P.M., Eastern Time, on the Expiration Date or the date on which this Warrant has been exercised in full.

This Warrant will be governed by and construed under the laws of the State of Delaware without regard to conflicts of laws principles that would require the application of any other law. Each party hereto agrees that all legal proceedings concerning the interpretations, enforcement and defense of the transactions contemplated by this Warrant (whether brought against a party hereto or its respective affiliates, directors, officers, shareholders, employees or agents) may be commenced in the state and federal courts sitting in the City of New York, Borough of Manhattan (the “New York Courts”). Each party hereto hereby irrevocably submits to the jurisdiction of the New York Courts for the adjudication of any dispute hereunder or in connection herewith or with any transaction contemplated hereby or discussed herein, and hereby irrevocably waives, and agrees not to assert in any suit, action or proceeding, any claim that it is not personally subject to the jurisdiction of any such court, or such New York Courts are improper or inconvenient venue for such proceeding; provided, however, that any suit seeking enforcement of this Warrant may be brought, at the Holder’s option, in the courts of any other jurisdiction where the Holder elects to bring such action. Each party hereby irrevocably waives personal service of process and consents to process being served in any such suit, action or proceeding by mailing a copy thereof via registered or certified mail or overnight delivery (with evidence of delivery) to such party at the address in effect for notices to it under this Note and agrees that such service shall constitute good and sufficient service of process and notice thereof. Nothing contained herein shall be deemed to limit in any way any right to serve process in any manner permitted by law. Each party hereto hereby irrevocably waives, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to this Warrant or the transactions contemplated hereby. If either party shall commence an action or proceeding to enforce any provisions of this Warrant, then the prevailing party in such action or proceeding shall be reimbursed by the other party for its reasonable attorney’s fees and other costs and expenses incurred with the investigation, preparation and prosecution of such action or proceeding.

In the case of a dispute as to the determination of the Exercise Price or the arithmetic calculation of the Warrant Shares, the Company shall submit the disputed determinations or arithmetic calculations via facsimile within five (5) Business Days of receipt of the Notice of Exercise giving rise to such dispute, as the case may be, to the Holder. If the Holder and the Company are unable to agree upon such determination or calculation of the Exercise Price or the Warrant Shares within three (3) Business Days of such disputed determination or arithmetic calculation being submitted to the Holder, then the Company shall, at its sole discretion, within five (5) Business Days, submit via facsimile (a) the disputed determination of the Exercise Price to an independent, reputable investment bank selected by the Company and approved by the Holder, or (b) the disputed arithmetic calculation of the Warrant Shares to the Company’s independent, outside accountant. The Company shall cause at its expense the investment bank or the accountant, as the case may be, to perform the determinations or calculations and notify the Company and the Holder of the results no later than ten (10) Business Days from the time it receives the disputed determinations or calculations; provided that, if such disputed determination or arithmetic calculation being submitted by the Holder is determined to be incorrect, then the expense of the investment bank or the accountant shall be the responsibility of the Holder. Such investment bank’s or accountant’s determination or calculation, as the case may be, shall be final, binding and conclusive upon the parties thereto.

Upon (a) any establishment by the Company of a record date of the holders of any class of securities for the purpose of determining the holders thereof who are entitled to receive any dividend or other distribution, or right or option to acquire securities of the Company, or any other right, or (b) any capital reorganization, reclassification, recapitalization, merger or consolidation of the Company with or into any other corporation, any transfer of all or substantially all the assets of the Company, or any voluntary or involuntary dissolution, liquidation or winding up of the Company, or the sale, in a single transaction, of a majority of the Company’s voting stock (whether newly issued, or from treasury, or previously issued and then outstanding, or any combination thereof), the Company shall mail to the Holder at least ten (10) Business Days, or such longer period as may be required by law, prior to the record date specified therein, a notice specifying (i) the date established as the record date for the purpose of such dividend, distribution, option or right and a description of such dividend, option or right, (ii) the date on which any such reorganization, reclassification, transfer, consolidation, merger, dissolution, liquidation or winding up, or sale is expected to become effective and (iii) the date, if any, fixed as to when the holders of record of Common Stock shall be entitled to exchange their shares of Common Stock for securities or other property deliverable upon such reorganization, reclassification, transfer, consolation, merger, dissolution, liquidation or winding up.

The Company shall reserve and keep available out of its authorized but unissued shares of Common Stock for issuance upon the exercise of this Warrant, free from pre-emptive rights, such number of shares of Common Stock for which this Warrant shall from time to time be exercisable. The Company will take all such reasonable action as may be necessary to assure that such Warrant Shares may be issued as provided herein without violation of any applicable law or regulation. Without limiting the generality of the foregoing, the Company covenants that it will use commercially reasonable efforts to take all such action as may be necessary or appropriate in order that the Company may validly and legally issue fully paid and non-assessable Warrant Shares upon the exercise of this Warrant and use commercially reasonable efforts to obtain all such authorizations, exemptions or consents, including but not limited to consents from the Company’s stockholders or Board or any public regulatory body, as may be necessary to enable the Company to perform its obligations under this Warrant.

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

Any term of this Warrant may be amended and the observance of any term of this Agreement may be waived (either generally or in a particular instance and either retroactively or prospectively), with the written consent of the Company and the Holders of a majority of the Warrant Shares issuable upon exercise of the Warrants.

This Warrant is not intended, and will not be construed, to create any rights in any parties other than the Company and the Holder, and no Person or entity may assert any rights as third-party beneficiary hereunder.
