VRINGO, INC.

Form of Common Stock Warrant

Vringo, Inc. (the “Company”), for value received, hereby certifies that [        ], or its registered assigns (the “Registered Holder”), is entitled, subject to the terms of this Common Stock Warrant (the “Warrant”) set forth below, to purchase from the Company, at any time after the date hereof and on or before December 29, 2014 (the “Expiration Date”), up to [        ] ([        ]) shares of common stock of the Company, par value $0.01 per share (the “Common Stock”), at a per share exercise price (the “Exercise Price”) equal to Forty-Six Cents ($0.46) per share (subject to adjustment as set forth in Section 2).

1. Exercise.

(a) Method of Exercise. This Warrant may be exercised by the Registered Holder, in whole or in part, by delivering the form appended hereto as Exhibit A duly executed by such Registered Holder (the “Exercise Notice”), at the principal office of the Company, or at such other office or agency as the Company may designate in writing prior to the date of such exercise, accompanied by payment in full of the Exercise Price payable with respect to the number of shares of Warrant Stock purchased upon such exercise. The Exercise Price must be paid by cash, check or wire transfer in immediately available funds for the Warrant Stock being purchased by the Registered Holder, except as provided in Section 1(c).

(b) Effective Time of Exercise. Each exercise of this Warrant shall be deemed to have been effected immediately prior to the close of business on the day on which the Exercise Notice has been delivered to the Company (the “Exercise Date”) as provided in this Section 1. At such time, the person or persons in whose name or names any certificates for Warrant Stock shall be issuable upon such exercise as provided in Section 1(d) below shall be deemed to have become the holder or holders of record of the Warrant Stock represented by such certificates.

(c) Cashless Exercise. Notwithstanding any provisions herein to the contrary, in lieu of exercising this Warrant in the manner set forth in Section 1(a), the Registered Holder may elect to exercise this Warrant, or a portion hereof, and to pay for the Warrant Stock by way of cashless exercise (a “Cashless Exercise”) unless at the Exercise Date, the sale of Common Stock to be received upon exercise of the Warrant is then registered, and such Common Stock is freely tradable pursuant to an effective Registration Statement under the Securities Act. If the Registered Holder wishes to effect a cashless

exercise, the Registered Holder shall deliver the Exercise Notice duly executed by such Registered Holder or by such Registered Holder’s duly authorized attorney, at the principal office of the Company, or at such other office or agency as the Company may designate in writing prior to the date of such exercise, in which event the Company shall issue to the Registered Holder the number of shares of Warrant Stock computed according to the following equation:

; where

X = the number of shares of Warrant Stock to be issued to the Registered Holder.

Y = the Warrant Stock purchasable under this Warrant or, if only a portion of the Warrant is being exercised, the portion of the Warrant Stock being exercised.

A = the Fair Market Value (defined below) of one share of Common Stock on the Exercise Date.

B = the Exercise Price (as adjusted pursuant to the provisions of this Warrant).

For purposes of this Section 1(c), the “Fair Market Value” of one share of Common Stock on the Exercise Date shall have one of the following meanings:

(1) if the Common Stock is traded on a national securities exchange, the Fair Market Value shall be deemed to be the average of the Closing Prices over a five trading day period ending on the Exercise Date. For the purposes of this Warrant, “Closing Price” means the final price at which one share of Common Stock is traded during any trading day; or

(2) if the Common Stock is traded over-the-counter, the Fair Market Value shall be deemed to be the average of the closing sales price over the thirty (30) day period ending three (3) days before the Exercise Date; or

(3) if neither (1) nor (2) is applicable, the Fair Market Value shall be at the commercially reasonable price per share which the Company could obtain on the Exercise Date from a willing buyer (not a current employee or director) for shares of Common Stock sold by the Company, from authorized but unissued shares, as determined in good faith by the Company’s Board of Directors.

For illustration purposes only, if this Warrant entitles the Registered Holder the right to purchase 100,000 shares of Warrant Stock and the Holder were to exercise this Warrant for 50,000 shares of Warrant Stock at a time when the Exercise Price was reduced to $1.00 and the Fair Market Value of each share of Common Stock was $2.00 on the Exercise Date, as applicable, the cashless exercise calculation would be as follows:

X = 50,000 ($2.00-$1.00)

            $2.00

X = 25,000

Therefore, the number of shares of Warrant Stock to be issued to the Holder after giving effect to the cashless exercise would be 25,000 shares of Warrant Stock and the Company would issue the Holder a new Warrant to purchase 50,000 shares of Warrant Stock, reflecting the portion of this Warrant not exercised by the Holder. For purposes of Rule 144 promulgated under the Securities Act of 1933, as amended (the “Securities Act”), it is intended, understood and acknowledged that the Warrant Stock issued in the cashless exercise transaction described pursuant to Section 1(c) shall be deemed to have been acquired by the Holder, and the holding period for the shares of Warrant Stock shall be deemed to have commenced, on the date of the Registered Holder’s acquisition of the Warrant.

(d) Delivery to Holder. As soon as practicable after the exercise of this Warrant in whole or in part, and in any event within three (3) business days thereafter (the “Warrant Stock Delivery Date”), the Company will cause to be issued in the name of, and delivered to, the Registered Holder, or as such Registered Holder (upon payment by such Registered Holder of any applicable transfer taxes) may direct:

(i) a certificate or certificates for the number of shares of Warrant Stock to which such Registered Holder shall be entitled, and

(ii) in case such exercise is in part only, a new warrant or warrants (dated the date hereof) of like tenor, calling in the aggregate on the face or faces thereof for the number of shares of Warrant Stock equal (giving effect to any adjustment therein) to the number of such shares called for on the face of this Warrant minus the number of such shares purchased by the Registered Holder upon such exercise as provided in Section 1(a).

(e) Compensation for Buy-In on Failure to Timely Deliver Certificates Upon Exercise. In addition to any other rights available to the Registered Holder, if the Company fails to transmit to the Registered Holder a certificate or the certificates representing the Warrant Stock pursuant to an exercise on or before the Warrant Stock Delivery Date, and if after such date the Registered Holder is required by its broker to purchase (in an open market transaction or otherwise) or the Registered Holder’s brokerage firm otherwise purchases, shares of Common Stock to deliver in satisfaction of a sale by the Registered Holder of the Warrant Stock which the Registered Holder anticipated receiving upon such exercise (a “Buy-In”), then the Company shall (A) pay in cash to the Holder the amount by which (x) the Registered Holder’s total purchase price (including brokerage commissions, if any) for the shares of Common Stock so purchased exceeds (y) the amount obtained by multiplying (1) the number of shares of Warrant Stock that the Company was required to deliver to the Registered Holder in connection with the exercise at issue times (2) the price at which the sell order giving rise to such purchase obligation was executed, and (B) at the option of the Registered Holder, either reinstate the portion of the Warrant and equivalent number of shares of Warrant Stock for which such exercise was not honored or deliver to the Registered 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 Registered Holder purchases Common Stock having a total purchase price of $11,000 to cover a Buy-In with respect to an attempted exercise of shares of Common Stock with an aggregate sale price giving rise to such purchase obligation of $10,000, under clause (A) of the immediately preceding sentence the Company shall be required to pay the Registered Holder $1,000. The Registered Holder shall provide the Company written notice indicating the amounts payable to the Registered Holder in respect of the Buy-In and, upon request of the Company, evidence of the amount of such loss.

(f) Registered Holder’s Exercise Limitations. The Company shall not effect any exercise of this Warrant, and a Registered Holder shall not have the right to exercise any portion of this Warrant, pursuant to Section 2 or otherwise, to the extent (but only to the extent) that the Registered Holder or any of the Registered Holder’s affiliates, would beneficially own in excess of the Beneficial Ownership Limitation (as defined below). For purposes of this Section 1(f), beneficial ownership shall be calculated in accordance with Section 13(d) of the Exchange Act (as defined herein) and the rules and

regulations promulgated thereunder, it being acknowledged by the Registered Holder that the Company is not representing to the Registered Holder that such calculation is in compliance with Section 13(d) of the Exchange Act and the Registered Holder is solely responsible for any schedules required to be filed in accordance therewith. To the extent that the limitation contained in this Section 1(f) applies, the determination of whether this Warrant is exercisable (in relation to other securities owned by the Registered Holder together with any Affiliates) and of which portion of this Warrant is exercisable shall be in the sole discretion of the Registered Holder, and the submission of an Exercise Notice shall be deemed to be the Registered Holder’s determination of whether this Warrant is exercisable (in relation to other securities owned by the Registered Holder together with any Affiliates) and of which portion of this Warrant is exercisable, in each case subject to the Beneficial Ownership Limitation, and the Company shall have no obligation to verify or confirm the accuracy of such determination. Upon the written or oral request of a Registered Holder, the Company shall within two business days confirm orally and in writing to the Registered Holder the number of shares of Common Stock then outstanding. 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 Warrant, by the Registered 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 Common Stock outstanding immediately after giving effect to the issuance of shares of Common Stock issuable upon exercise of this Warrant. The Registered Holder, upon not less than 61 days’ prior notice to the Company, may increase or decrease the Beneficial Ownership Limitation provisions of this Section 1(f), provided that the Beneficial Ownership Limitation shall in no event exceed 9.99% of the number of shares of Common Stock outstanding immediately after giving effect to the issuance of shares of Common Stock upon exercise of this Warrant held by the Registered Holder and the provisions of this Section 1(f) shall continue to apply. Any such increase or decrease will not be effective until the 61st day after such notice is delivered to the Company. The provisions of this paragraph shall be construed and implemented in a manner otherwise than in strict conformity with the terms of this Section 1(f) to correct this paragraph (or any portion hereof) which may be defective or inconsistent with the intended Beneficial Ownership Limitation herein contained or to make changes or supplements necessary or desirable to properly give effect to such limitation. The limitations contained in this paragraph shall apply to a successor holder of this Warrant.

2. Adjustments.

(a) Stock Splits and Dividends. If the outstanding shares of the Company’s Common Stock shall be subdivided into a greater number of shares or a dividend in Common Stock shall be paid in respect of Common Stock, the Exercise Price in effect immediately prior to such subdivision or at the record date of such dividend shall, simultaneously with the effectiveness of such subdivision or immediately after the record date of such dividend, be proportionately reduced and the number of Warrant Stock issuable upon exercise of the Warrant shall be proportionately increased. If the outstanding shares of Common Stock shall be combined into a smaller number of shares, the Exercise Price in effect immediately prior to such combination shall, simultaneously with the effectiveness of such combination, be proportionately increased and the number of shares of Warrant Stock issuable upon exercise of the Warrant shall be proportionately decreased. Notwithstanding anything to the contrary, in the event the first such combination subsequent to the issuance of the Warrant is the reverse split of the Common Stock in a range between 1 for 6 and 1 for 6.4 in connection with an initial public offering (“IPO”) of the Common Stock (“Reverse Split”), the Exercise Price shall, simultaneously with the effectiveness of the Reverse Split, be increased to Two Dollars and Seventy-Five Cents ($2.75), provided that no other adjustments pursuant to Section 2 have occurred prior to such time.

(b) Fundamental Transaction. If, at any time while this 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, a “Fundamental Transaction”), then, upon any subsequent exercise of this Warrant, the Registered Holder shall have the right to receive, for each share of Warrant Stock 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 merger, consolidation or disposition of assets by a holder of the number of shares of Common Stock for which this Warrant is exercisable immediately prior to such event. 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 Registered Holder shall be given the same choice as to the Alternate Consideration it receives upon any exercise of this 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 Registered Holder a new warrant consistent with the foregoing provisions and evidencing the Registered 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 2(b) and insuring that this 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 (1) that is an all cash transaction, (2) a “Rule 13e-3 transaction” as defined in Rule 13e-3 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or (3) a Fundamental Transaction involving a person or entity not traded on a national securities exchange, the Nasdaq Global Select Market, the Nasdaq Global Market, the Nasdaq Capital Market or the OTC Bulletin Board, then the Company or any successor entity shall pay at the Registered Holder’s option, exercisable at any time concurrently with or within 30 days after the later of the consummation of the Fundamental Transaction or receipt by the Registered Holder of notice of the Fundamental Transaction pursuant to Section 6(d) hereof, an amount of cash equal to the value of this Warrant as determined in accordance with the Black Scholes Option Pricing Model obtained from the “OV” function on Bloomberg L.P. using (A) (i) if the Common Stock is registered under the Exchange Act, a price per share of Common Stock equal to the volume weighted average price per share the Common Stock for the Trading Day immediately preceding the date of consummation of the applicable Fundamental Transaction or (ii) if the Common Stock is not registered under the Exchange Act, a price per share of Common Stock equal to the price paid per share of Common Stock by the successor or acquiring corporation in the Fundamental Transaction, (B) a risk-free interest rate corresponding to the U.S. Treasury rate for the 30 day period immediately prior to the consummation of the applicable Fundamental Transaction, (C) an expected volatility equal to the greater of (i) 100% or (ii) 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 Fundamental Transaction and the Expiration Date.

(c) Subsequent Rights Offerings. If the Company, at any time while the Warrant is outstanding, shall issue rights, options or warrants to all holders of Common Stock (and not to the Registered Holders) entitling them to subscribe for or purchase shares of Common Stock at a price per share less than Fair Market Value at the record date mentioned below, then the Exercise Price shall be multiplied by a fraction, of which the denominator shall be the number of shares of the Common Stock outstanding on the date of issuance of such rights, options or warrants plus the number of additional shares of Common Stock offered for subscription or purchase, and of which the numerator shall be the number of shares of the Common Stock outstanding on the date of issuance of such rights, options or warrants plus the number of shares which the aggregate offering price of the total number of shares so offered (assuming receipt by the Company in full of all consideration payable upon exercise of such rights, options or warrants) would purchase at such Fair Market Value. Such adjustment shall be made whenever such rights, options or warrants are issued, and shall become effective immediately after the record date for the determination of stockholders entitled to receive such rights, options or warrants.

(d) Pro Rata Distributions. If the Company, at any time while this Warrant is outstanding, shall distribute to all holders of Common Stock (and not to the Registered Holders) 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 (which shall be subject to Section 2(e)), 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 Fair Market Value determined as of the record date mentioned above, and of which the numerator shall be such Fair Market Value on such record date less the then per share fair market value at such record date of the portion of such assets or evidence of indebtedness or rights or warrant 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 Registered 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.

(e) Dilutive Issuances. If the Company shall sell or grant any option to purchase, or sell or grant any right to reprice, or otherwise dispose of or issue (or announce any offer, sale, grant or any option to purchase or other disposition) any Common Stock or any security convertible or exercisable for Common Stock (a “Common Stock Equivalent”) entitling the holder to acquire shares of Common Stock, at an effective price per share less than the then Exercise Price (such lower price, the “Base Share Price” and such issuances collectively, a “Dilutive Issuance”) (if the holder of the Common Stock or Common Stock Equivalents so issued shall at any time, whether by operation of purchase price adjustments, reset provisions, floating conversion, exercise or exchange prices or otherwise, or due to warrants, options or rights per share which are issued in connection with such issuance, be entitled to receive shares of Common Stock at an effective price per share that is less than the Exercise Price, such issuance shall be deemed to have occurred for less than the Exercise Price on such date of the Dilutive Issuance), then, the Exercise Price shall be reduced and only reduced to equal the Base Share Price and the number of shares of Warrant Stock issuable hereunder shall be increased such that the aggregate Exercise Price payable hereunder, after taking into account the decrease in the Exercise Price, shall be equal to the aggregate Exercise Price prior to such adjustment. Such adjustment shall be made whenever such Common Stock or Common Stock Equivalents are issued. Notwithstanding the foregoing, no adjustments shall be made under this Section 2(e) with respect to any Exempt Issuance. “Exempt Issuance” shall mean the issuance of (i) up to 2,791,000 shares of Common Stock or Common Stock Equivalents (prior to the Reverse Split) issued or issuable to employees, directors and consultants pursuant to any equity compensation or similar plan currently existing; (ii) shares of Common Stock or Common Stock Equivalents issuable to employees, directors and consultants in connection with the initial public offering of the Company (the “IPO”), including options granted to such persons subsequent to the IPO equal to twenty percent (20%) of the Company’s shares of Common Stock subsequent to the IPO on

a fully diluted basis, including any shares issued pursuant to the exercise of an over-allotment option by an underwriter in connection with the IPO (“Fully Diluted Common Stock”) (iii) shares of Common Stock or Common Stock Equivalents issuable to employees, directors and consultants pursuant to any equity compensation or similar plan currently existing or duly adopted by the Company’s board of directors following the date hereof the primary purpose of which is to provide compensation and not to provide financing for the Company, other than issuances during the twelve months subsequent to the consummation of the IPO and issuances in any fiscal year subsequent to the consummation of the IPO that exceed two percent (2%) of the Company’s shares of Fully Diluted Common Stock; (iv) securities issuable upon the exercise, exchange of, conversion or redemption of, or payment of liquidated or similar damages on, any securities issued hereunder; (v) other securities exercisable, exchangeable for, convertible into, or redeemable for shares of Common Stock or Common Stock Equivalents issued and outstanding on the date hereof on the terms in effect for such securities on the date hereof; and (vi) any securities, issued or issuable in connection with a bona fide strategic transaction approved by the board of directors or a committee thereof, the primary purpose of which is not to provide financing to the Company.

The Company shall notify the Registered Holder, in writing, no later than three (3) trading days following the issuance of any Common Stock or Common Stock Equivalents subject to this Section 2(e), indicating therein the applicable issuance price, or applicable reset price, exchange price, conversion price and other pricing terms (such notice, the “Dilutive Issuance Notice”). For purposes of clarification, whether or not the Company provides a Dilutive Issuance Notice pursuant to this Section 2(e), upon the occurrence of any Dilutive Issuance, after the date of such Dilutive Issuance the Holder is entitled to receive a number of shares of Warrant Stock based upon the Base Share Price regardless of whether the Holder accurately refers to the Base Share Price in the Notice of Exercise. For purposes of the adjusted Exercise Price under this Section 2(e), the following shall be applicable:

i. Issuance of Options. If the Company in any manner grants any Options and the lowest price per share for which one share of Common Stock is issuable upon the exercise of any such Option or upon conversion, exercise or exchange of any Convertible Securities issuable upon exercise of any such Option is less than the Base Share Price, then such share of Common Stock shall be deemed to be outstanding and to have been issued and sold by the Company at the time of the granting or sale of such Option for such price per share. For purposes of this Section 2(e)(i), the “lowest price per share for which one share of Common Stock is issuable upon exercise of such Options or upon conversion, exercise or exchange of such Convertible Securities issuable upon exercise of any such Option” shall be equal to the sum of the lowest amounts of consideration (if any) received or receivable by the Company with respect to any one share of Common Stock upon the granting or sale of the Option, upon exercise of the Option and upon conversion, exercise or exchange of any Convertible Security issuable upon exercise of such Option. No further adjustment of the Exercise Price or number of shares of Warrant Stock shall be made upon the actual issuance of such shares of Common Stock or of such Convertible Securities upon the exercise of such Options or upon the actual issuance of such shares of Common Stock upon conversion, exercise or exchange of such Convertible Securities.

ii. Issuance of Convertible Securities. If the Company in any manner issues or sells any Convertible Securities and the lowest price per share for which one share of Common Stock is issuable upon the conversion, exercise or exchange thereof is less than the Base Share Price, then such share of Common Stock shall be deemed to be outstanding and to have been issued and sold by the Company at the time of the issuance or sale of such Convertible Securities for such price per share. For the purposes of this Section 2(e)(ii), the “lowest price per share for which one share of Common Stock is issuable upon the conversion, exercise or exchange thereof” shall be equal to the sum of the lowest amounts of consideration (if any) received or receivable by the Company with respect to one share of

Common Stock upon the issuance or sale of the Convertible Security and upon conversion, exercise or exchange of such Convertible Security. No further adjustment of the Exercise Price or number of shares of Warrant Stock shall be made upon the actual issuance of such shares of Common Stock upon conversion, exercise or exchange of such Convertible Securities, and if any such issue or sale of such Convertible Securities is made upon exercise of any Options for which adjustment of this Warrant has been or is to be made pursuant to other provisions of this Section 2(e), no further adjustment of the Exercise Price or number of shares of Warrant Stock shall be made by reason of such issue or sale.

iii. Change in Option Price or Rate of Conversion. If the purchase price provided for in any Options, the additional consideration, if any, payable upon the issue, conversion, exercise or exchange of any Convertible Securities, or the rate at which any Convertible Securities are convertible into or exercisable or exchangeable for shares of Common Stock increases or decreases at any time, the Exercise Price and the number of shares of Warrant Stock in effect at the time of such increase or decrease shall be adjusted to the Exercise Price and the number of shares of Warrant Stock which would have been in effect at such time had such Options or Convertible Securities provided for such increased or decreased purchase price, additional consideration or increased or decreased conversion rate, as the case may be, at the time initially granted, issued or sold. For purposes of this Section 2(e)(iii), if the terms of any Option or Convertible Security that was outstanding as of the date of issuance of this Warrant are increased or decreased in the manner described in the immediately preceding sentence, then such Option or Convertible Security and the shares of Common Stock deemed issuable upon exercise, conversion or exchange thereof shall be deemed to have been issued as of the date of such increase or decrease. No adjustment pursuant to this Section 2(e)(iii) shall be made if such adjustment would result in an increase of the Exercise Price then in effect or a decrease in the number of shares of Warrant Stock.

iv. Calculation of Consideration Received. In case any Option is issued in connection with the issue or sale of other securities of the Company, together comprising one integrated transaction in which no specific consideration is allocated to such Options by the parties thereto, the Options will be deemed to have been issued for a consideration of $0.01. If any shares of Common Stock, Options or Convertible Securities are issued or sold or deemed to have been issued or sold for cash, the consideration received therefor will be deemed to be the net amount received by the Company therefor. If any shares of Common Stock, Options or Convertible Securities are issued or sold for a consideration other than cash, the amount of such consideration received by the Company will be the fair value of such consideration, except where such consideration consists of publicly traded securities, in which case the amount of consideration received by the Company will be the Closing Sale Price of such security on the date of receipt. If any shares of Common Stock, Options or Convertible Securities are issued to the owners of the non-surviving entity in connection with any merger in which the Company is the surviving entity, the amount of consideration therefor will 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. The fair value of any consideration other than cash or publicly traded securities will be determined jointly by the Company and the holders of the Warrants representing at least a majority of shares of Common Stock underlying the Warrants then outstanding (“Required Holders”). If such parties are unable to reach agreement within ten (10) days after the occurrence of an event requiring valuation (the “Valuation Event”), the fair value of such consideration will be determined within five (5) Business Days after the tenth day following the Valuation Event by an independent, reputable appraiser jointly selected by the Company and the Required Holders. The determination of such appraiser shall be final and binding upon all parties absent manifest error and the fees and expenses of such appraiser shall be borne by the Company.

v. Record Date. If the Company takes a record of the holders of shares of Common Stock for the purpose of entitling them (A) to receive a dividend or other distribution payable in shares of Common Stock, Options or in Convertible Securities or (B) to subscribe for or purchase shares of Common Stock, Options or Convertible Securities, then such record date will 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.

(f) Adjustment Certificate. When any adjustment is required to be made in the Exercise Price pursuant to this Section 2, the Company shall promptly mail to the Registered Holder a certificate setting forth (i) a brief statement of the facts requiring such adjustment, (ii) the Exercise Price after such adjustment and (iii) the kind and amount of stock or other securities or property into which this Warrant shall be exercisable after such adjustment.

3. Transfers.

(a) Unregistered Security. The holder of this Warrant acknowledges that this Warrant and the Warrant Stock have not been registered under the Securities Act and agrees not to sell, pledge, distribute, offer for sale, transfer or otherwise dispose of this Warrant or any Warrant Stock issued upon its exercise in the absence of (i) an effective registration statement under the Securities Act as to this Warrant or such Warrant Stock and registration or qualification of this Warrant or such Warrant Stock under any applicable U.S. federal or state securities law then in effect or (ii) an opinion of counsel, reasonably satisfactory to the Company, that such registration and qualification are not required. Each certificate or other instrument for Warrant Stock issued upon the exercise of this Warrant shall bear a legend substantially to the foregoing effect.

(b) Transferability. Subject to the provisions of Section 3(a) hereof, this Warrant and all rights hereunder are transferable, in whole or in part, to (i) any entity controlling, controlled by or under common control of the Registered Holder, or (ii) to any other proposed transferee by surrendering the Warrant with a properly executed assignment (in the form of Exhibit B hereto) at the principal office of the Company.

(c) Warrant Register. The Company will maintain a register containing the names and addresses of the Registered Holders of this Warrant. Until any transfer of this Warrant is made in the warrant register, the Company may treat the Registered Holder of this Warrant as the absolute owner hereof for all purposes; provided, however, that if this Warrant is properly assigned in blank, the Company may (but shall not be required to) treat the bearer hereof as the absolute owner hereof for all purposes, notwithstanding any notice to the contrary. Any Registered Holder may change such Registered Holder’s address as shown on the warrant register by written notice to the Company requesting such change.

4. No Impairment. The Company will not, by amendment of its certificate of incorporation or through reorganization, consolidation, merger, dissolution, sale of assets or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of this Warrant, but will (subject to Section 12 below) at all times in good faith assist in the carrying out of all such terms and in the taking of all such action as may be necessary or appropriate in order to protect the rights of the Registered Holder of this Warrant against impairment.

5. Termination. This Warrant (and the right to purchase securities upon exercise hereof) shall terminate at 5:00 p.m., Eastern time, on the Expiration Date.

6. Notices of Certain Transactions. In case:

(a) the Company shall take a record of the holders of its Common Stock (or other stock or securities at the time deliverable upon the exercise of this Warrant) for the purpose of entitling or enabling them to receive any dividend or other distribution, or to receive any right to subscribe for or purchase any shares of stock of any class or any other securities, or to receive any other right, to subscribe for or purchase any shares of stock of any class or any other securities, or to receive any other right, or

(b) of any capital reorganization of the Company, any reclassification of the capital stock of the Company, any consolidation or merger of the Company, any consolidation or merger of the Company with or into another corporation (other than a consolidation or merger in which the Company is the surviving entity), or any transfer of all or substantially all of the assets of the Company, or

(c) of the voluntary or involuntary dissolution, liquidation or winding-up of the Company, or

(d) of any Fundamental Transaction,

then, and in each such case, the Company will mail or cause to be mailed to the Registered Holder of this Warrant a notice specifying, as the case may be, (i) the date on which a record is to be taken for the purpose of such dividend, distribution or right, and stating the amount and character of such dividend, distribution or right, or (ii) the effective date on which such reorganization, reclassification, consolidation, merger, transfer, dissolution, liquidation, winding-up or Fundamental Transaction is to take place, and the time, if any is to be fixed, as of which the holders of record of Common Stock (or such other stock or securities at the time deliverable upon such reorganization, reclassification, consolidation, merger, transfer, dissolution, liquidation or winding-up) are to be determined. Failure to send such notice shall not act to invalidate any such transaction.

(c) Disposition of Registered Holder’s Rights. In no event will the Registered Holder make a disposition of the Warrant or the Warrant Stock issuable upon exercise of the Warrant in the absence of (i) an effective registration statement under the Securities Act as to this Warrant or such Warrant Stock and registration or qualification of this Warrant or such Warrant Stock under any applicable U.S. federal or state securities law then in effect or (ii) an opinion of counsel, reasonably satisfactory to the Company, that such registration and qualification are not required. Whenever the restrictions imposed hereunder shall terminate, as hereinabove provided, the Registered Holder or holder of a share of common stock then outstanding as to which such restrictions have terminated shall be entitled to receive from the Company, without expense to such holder, one or more new certificates for the Warrant or for such shares of Common Stock not bearing any restrictive legend.

(d) Financial Risk. The Registered Holder has such business and financial experience as is required to give it the capacity to protect its own interests in connection with its investment.

(b) Valid Issuance. The Warrant Stock is duly authorized and reserved for issuance, and when issued and delivered in accordance with the terms of this Warrant will be duly and validly issued, fully paid and nonassessable.

(c) No Conflict. The execution and delivery of this Warrant do not, and the consummation of the transactions contemplated hereby will not, conflict with, or result in any violation of, breach or default (with or without notice or lapse of time, or both), or give rise to a right of termination, cancellation or acceleration of any obligation or to a loss of a material benefit, under, any provision of the Certificate of Incorporation or bylaws of the Company or any order, decree, statute, law, ordinance, rule, listing requirement or regulation applicable to the Company, its properties or assets, which conflict, violation, default or right would have a material adverse effect on the business, properties, prospects, financial condition or operations of the Company.
