The Holders of the Notes (other than the Holder) are referred to herein as the “Other Holders” and the Other Holders and the Holder are collectively referred to herein as the “Holders”.

1BWarrants.  In connection with the issuance and sale of the Notes and pursuant to the Purchase Agreement, the Company has authorized the issuance of and will concurrently issue to each Holder a Common Stock Purchase Warrant representing the right to purchase initially such number of shares of Common Stock of the Company equal to the Principal Amount specified on the face of such Holder’s Note (as the same may be amended, restated, supplemented or otherwise modified from time to time, collectively, the “Warrants”), such Warrants to be in the form of Exhibit B.  The Holder shall receive a Warrant (as the same may be amended, restated, supplemented or otherwise modified from time to time, the “Warrant”) representing the right to purchase an aggregate amount of shares of Common Stock of the Company as specified in Exhibit A.

1CAllocation of Purchase Price.  The aggregate purchase price for this Note and the Warrant to be purchased by the Holder pursuant to the terms hereof and of the Warrant (the “Purchase Price”) shall be $[__]. The Holder shall pay $1.00 for each $1.00 of Principal Amount and the Warrant to be purchased by the Holder. The Holder and the Company agree that this Note and the Warrant constitute an “investment unit” for purposes of Section 1273(c)(2) of the Code. The Holder and the Company mutually agree that the allocation of the issue price of such investment unit between this Note and the Warrant in accordance with Section 1273(c)(2) of the Code and Treasury Regulation Section 1.1273-2(h) shall be an aggregate amount of $0.384 per $1.00 of Purchase Price to be allocated to the Warrant and the balance of the Purchase Price allocated to this Note, and neither the Holder nor the Company shall take any position inconsistent with such allocation in any tax return or in any judicial or administrative proceeding in respect of taxes.

Certain capitalized terms used in this Note are defined in paragraph 11; references to a paragraph are, unless otherwise specified, to one of the paragraphs of this Note and references to an “Exhibit” or “Schedule” are, unless otherwise specified, to one of the exhibits or schedules attached to this Note.

2INTEREST. 

2AInterest Rate.  Subject to paragraph 2B below, this Note shall bear interest (computed on the basis of a 365-day year and actual days elapsed) (i) on the unpaid balance of the Principal Amount at the rate of 4.00% per annum from the date hereof, payable on the Maturity Date and quarterly in arrears on the last day of September, December, March and June in each year (each, an “Interest Payment Date”), commencing with the first such date next succeeding the date hereof (the “First Interest Payment Date”), until the principal hereof shall have become due and payable, and upon any prepayment or repayment of this Note, and (ii) following the occurrence and during the continuance of an Event of Default (other than an Event of Default arising under paragraph 7A(iv)), on the unpaid balance of the Principal Amount and any interest (including, for the avoidance of doubt, Accrued Interest), in each case in respect of the Note, automatically at a rate per annum from time to time equal to the Default Rate, payable quarterly as aforesaid (or at the option of the Holder, on demand).  

2BInterest Payments.  On each Interest Payment Date, interest accrued on this Note since its issuance (in the case of the First Interest Payment Date) or otherwise since the last Interest Payment Date shall be paid in cash.  Notwithstanding the foregoing, in lieu of making the interest payments on this Note in cash on any Interest Payment Date, the Company may, at its option, with notice to the Holder at the commencement of the applicable interest period, elect to accrue interest for such interest period (such accrued interest, including all additional interest in respect of such interest as described further below, the “Accrued Interest”).  All such Accrued Interest shall bear additional interest (computed on the basis of a 365-day year and actual days elapsed) at the rate of 4.00% per annum from the date of the applicable Interest Payment Date, compounded quarterly.  For the avoidance of doubt, the Accrued Interest shall not be added to the outstanding Principal Amount.  The Accrued Interest shall be due and payable upon the earliest of (i) the conversion of this Note in accordance with paragraph 3, (ii) the exercise of the Holder’s put option or rights to prepayment in accordance with paragraphs 5A(2) or 5A(3), (iii) the Company’s repayment in full in cash of this Note and all other obligations hereunder and (iv) the Maturity Date.  Notwithstanding anything contained herein to the contrary, if the Company elects for interest to accrue, then (a) the Company may, upon ten (10) Business Days’ prior notice to the Holder, elect to repay any such Accrued Interest in cash at any time and from time to time and (b) the Holder may elect in writing (such request, an “Accrued Interest Conversion Election Notice”) at any time and from time to time, including upon its receipt of the notice referenced in clause (a) above, to have the Company convert any such Accrued Interest into shares of Common Stock in accordance with paragraph 3B below.

3CONVERSION; LIMITATION ON BENEFICIAL OWNERSHIP.

3AConversion of Principal.  At any time and from time to time following the Funding Date, subject to paragraphs 3C and 3K hereof, the unpaid Principal Amount then outstanding under this Note shall be convertible (in whole or in part), at the option of the Holder, into such number of fully paid and non-assessable shares of Common Stock as is determined by dividing (i) that portion of the unpaid Principal Amount of this Note then outstanding that the Holder elects to convert by (ii) the Applicable Conversion Price then in effect on the date on which the Company 

receives a notice of conversion in the form attached hereto as Exhibit D (each, a “Conversion Notice”) from the Holder, duly executed, to the Company (each, a “Principal Conversion Date”). With respect to partial conversions of this Note, the Company shall keep written records of the amount of this Note converted as of each Conversion Date.

3BConversion of Accrued Interest.  In the event that the Holder elects to have Accrued Interest converted into shares of Common Stock, subject to paragraphs 3C and 3K hereof, such Accrued Interest shall be convertible into such number of fully paid and non-assessable shares of Common Stock as is determined by dividing (i) that portion of the unpaid Accrued Interest that the Holder elects to convert by (ii) the greater of (a) the last closing bid price of a share of the Company’s Common Stock as reported on the NASDAQ on the date the Company receives the Accrued Interest Conversion Election Notice (each, an “Accrued Interest Conversion Date”) and (b) the Applicable Conversion Price (each, an “Accrued Interest Conversion Price”).

3CMechanics of Conversion.

3C(1)Issuance of Certificates.  Not later than three (3) Trading Days after each Conversion Date (each, a “Delivery Date”), the Company shall, at its expense (including the payment by it of any applicable issue or stamp taxes), cause to be issued in the name of and delivered to the Holder, or as the Holder may direct, a certificate or certificates evidencing the number of fully paid and nonassessable shares of Common Stock (which number shall be rounded down to the nearest whole share in the event any fractional share may otherwise be issuable upon such conversion and the Company shall pay a cash adjustment to the Holder in respect of such final fraction in an amount equal to such fraction multiplied by the Applicable Conversion Price or Accrued Interest Conversion Price, as applicable) to which the Holder shall be entitled upon conversion of all or any portion of the Principal Amount or Accrued Interest (the “Conversion Shares”), in such denominations as may be requested by the Holder, which certificate or certificates shall be free of restrictive and trading legends (except for any such legends as may be required under the Securities Act).  In lieu of delivering physical certificates for the shares of Common Stock issuable upon any conversion of all or any portion of the Principal Amount or Accrued Interest, provided the Company’s transfer agent is participating in the Depository Trust Company (“DTC”) Fast Automated Securities Transfer program or a similar program, upon request of the Holder, the Company shall cause its transfer agent to electronically transmit such shares of Common Stock issuable upon conversion of all or any portion of the Principal Amount or Accrued Interest to the Holder (or its designee), by crediting the account of the Holder’s (or such designee’s) broker with DTC through its Deposit Withdrawal Agent Commission system (provided that the same time periods herein as for stock certificates shall apply) as instructed by the Holder (or its designee).

3C(2)Buy-Ins.  In addition to any other rights available to the Holder, if the Company fails to cause its transfer agent to transmit to the Holder the Conversion Shares pursuant to a conversion on or before the Delivery Date, and if after such date the Holder is required by its broker 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 Conversion Shares which the Holder anticipated receiving upon such exercise (a “Buy-In”), then the Company shall (i) pay in cash to the Holder the amount, if any, by which (a) the Holder’s total purchase price (including brokerage commissions, if any) for the shares of Common Stock so purchased exceeds (b) the amount obtained by multiplying (1) the number of Conversion Shares that the Company was required to deliver to the Holder in connection with the conversion at issue times (2) the price at which the sell order giving rise to such purchase obligation was executed, and (ii) at the option of the Holder, either reinstate the Principal Amount (or applicable portion thereof) or Accrued Interest, as applicable, for which such conversion was not honored (in which case such conversion shall be deemed rescinded) or deliver to the Holder the number of shares of Common Stock that would have been issued had the Company timely complied with its exercise and delivery obligations hereunder.  For example, if the Holder purchases Common Stock having a total purchase price of $11,000 to cover a Buy-In with respect to an attempted conversion of all or any portion of the Principal Amount or Accrued Interest, as applicable, into shares of Common Stock with an aggregate sale price giving rise to such purchase obligation of $10,000, under clause (i) of the immediately preceding sentence the Company shall be required to pay the Holder $1,000.  The Holder shall provide the Company notice indicating the amounts payable to the Holder in respect of the Buy-In and evidence of the amount of such loss. Nothing herein shall limit the Holder’s right to pursue a decree of specific performance and/or injunctive relief with respect to 

the Company’s failure to timely deliver shares of Common Stock upon conversion of all or any portion of the Principal Amount or Accrued Interest, as required pursuant to the terms hereof.

3DAdjustment of Conversion Price.  Until the Note has been paid in full or converted in full, the Applicable Conversion Price shall be subject to adjustment from time to time as follows (but shall not be increased, other than pursuant to paragraph 3D(1) hereof):

3D(1)Adjustments for Stock Splits and Combinations.  If the Company shall at any time or from time to time after the Funding Date effect a split of the outstanding Common Stock, the Applicable Conversion Price in effect immediately prior to the stock split shall be proportionately decreased.  If the Company shall at any time or from time to time after the Funding Date combine the outstanding shares of Common Stock, the Applicable Conversion Price in effect immediately prior to the combination shall be proportionately increased.  Any adjustments under this paragraph 3D(1) shall be effective at the close of business on the date the stock split or combination occurs.

3D(2)Adjustments for Certain Dividends and Distributions.  If the Company shall at any time or from time to time after the Funding Date make or issue or set a record date for the determination of holders of Common Stock entitled to receive a dividend or other distribution payable in shares of Common Stock, then, and in each event, the Applicable Conversion Price in effect immediately prior to such event shall be decreased as of the time of such issuance by multiplying the Applicable Conversion Price then in effect by a fraction:

(i)the numerator of which shall be the total number of shares of Common Stock issued and outstanding immediately prior to the time of such issuance; and 

(ii)the denominator of which shall be the total number of shares of Common Stock issued and outstanding immediately prior to the time of such issuance plus the number of shares of Common Stock issued in payment of such dividend or distribution.

3D(3)Adjustment for Other Dividends and Distributions.  If the Company shall at any time or from time to time after the Funding Date make or issue or set a record date for the determination of holders of Common Stock entitled to receive, a dividend or other distribution payable in securities of the Company (other than as described in paragraph 3D(1) or 3D(2)) or in cash or other property, then and in each such event provision shall be made so that the Holder shall receive upon conversion hereof, in addition to the number of shares of Common Stock issuable hereunder, the kind and amount of securities of the Company, cash or other property which the Holder would have been entitled to receive had this Note been converted on the date of such event and had the Holder thereafter, during the period from the date of such event to and including the Principal Conversion Date or the Accrued Interest Conversion Date, as the case may be, retained any such securities receivable during such period, giving application to all adjustments called for during such period under this paragraph 3D with respect to the rights of the Holder.

3D(4)Adjustments for Reclassification, Exchange, Substitution, Reorganization, Consolidation, Merger, Etc.  If the Common Stock at any time or from time to time after the Funding Date shall be changed to the same or different number of shares or other securities of any class or classes of stock or other property, whether by reclassification, exchange, substitution, reorganization, consolidation, merger, transfer of all or substantially all of the Company’s properties or assets to any other person under any plan or arrangement contemplating the dissolution of the Company, or otherwise (other than by way of a stock split or combination of shares or stock dividends provided for in paragraphs 3D(1), 3D(2) or 3D(3) hereof), then, and in each event, an appropriate revision to the Applicable Conversion Price shall be made and provisions shall be made (by adjustments of the Applicable Conversion Price or otherwise) so that thereafter this Note shall be convertible into the kind and amount of shares of stock or other securities or other property receivable upon reclassification, exchange, substitution, reorganization, consolidation, merger, transfer of all or substantially all of the Company’s properties or assets to any other person under any plan or arrangement contemplating the dissolution of the Company or other change, by holders of the number of shares of Common Stock into which such Note might have been converted immediately prior to such reclassification, exchange, substitution, reorganization, consolidation, merger, transfer of all or substantially all of the Company’s properties or assets to any 

other person under any plan or arrangement contemplating the dissolution of the Company or other change, all subject to further adjustment as provided herein.

3D(5)Other Events.  If any event occurs of the type contemplated by the provisions of this paragraph 3D but not expressly provided for by such provisions, then the Company’s board of directors, acting in good faith and consistent with its fiduciary duties, shall make an appropriate adjustment in the Applicable Conversion Price so as to protect the rights of the Holder.

3ERecord Date. In the event of:

(i)any taking by the Company of a record 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 any right to subscribe for, purchase or otherwise acquire any shares of stock of any class or any other securities or property, or to receive any other right; or

(ii)any capital reorganization of the Company, any reclassification or recapitalization of the capital stock of the Company or any transfer of all or substantially all the assets of the Company to or any consolidation or merger of the Company with or into any other Person or any other Change of Control; or

(iii)any voluntary or involuntary dissolution, liquidation or winding-up of the Company;

then, and in each such event, the Company will mail or cause to be mailed to the Holder a notice specifying (a) the date on which any such 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 (b) the date on which any such reorganization, reclassification, recapitalization, transfer, consolidation, merger, dissolution, liquidation or winding-up is anticipated to take place, and the time, if any is to be fixed, as of which the holders of record of Common Stock (or other Equity Interests) shall be entitled to exchange their shares of Common Stock (or other Equity Interests) for securities or other property deliverable on such reorganization, reclassification, recapitalization, transfer, consolidation, merger, dissolution, liquidation or winding-up.  Such notice shall be mailed at least fifteen (15) days prior to the date specified in such notice on which any such action is to be taken.

3FNo Impairment. The Company will not, by amendment of its Organizational Documents or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of this Note, but will at all times in good faith assist in the carrying out of all such terms and in taking all such action as may be necessary or appropriate in order to protect the rights of the Holder against impairment.  Without limiting the generality of the foregoing, the Company (i) will not increase the par value of any shares of stock receivable on the conversion of all or any portion of the Principal Amount or Accrued Interest, as applicable, above the amount payable therefor on such conversion, and (ii) will 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 shares of stock on the conversion of all or any portion of the Principal Amount or Accrued Interest, as applicable.

3GCertificates as to Adjustments. Upon the occurrence of each adjustment of the Applicable Conversion Price pursuant to this paragraph 3, the Company at its expense shall promptly compute such adjustment in accordance with the terms hereof and furnish to the Holder a certificate setting forth such adjustment, showing in detail the facts upon which such adjustment is based. The Company shall, upon written request of the Holder, at any time, furnish or cause to be furnished to the Holder a like certificate setting forth such adjustments, the Applicable Conversion Price in effect at the time, and the number of shares of Common Stock and the amount, if any, of other securities or property which at the time would be received upon the conversion of this Note.  

3HIssue Taxes. The Company shall pay any and all issue and other taxes, excluding federal, state or local income taxes, that may be payable in respect of any issue or delivery of shares of Common Stock on conversion of all 

or any portion of the Principal Amount or Accrued Interest; provided, however, that the Company shall not be obligated to pay any transfer taxes resulting from any transfer requested by the Holder in connection with any such conversion.

3IReservation of Common Stock.  The Company shall at all times after the Funding Date and while this Note shall be outstanding, reserve and keep available out of its authorized but unissued Common Stock, such number of shares of Common Stock as shall from time to time be sufficient to effect the conversion of all or any portion of the Principal Amount and all Accrued Interest thereon (disregarding for this purpose any and all limitations of any kind on such conversion).  The Company shall, from time to time in accordance with the Delaware General Corporation Law, increase the authorized number of shares of Common Stock or take other effective action if at any time the unissued number of authorized shares shall not be sufficient to satisfy the Company’s obligations under this paragraph 3.

3JRegulatory Compliance. 

3J(1)General.  If any shares of Common Stock to be reserved for the purpose of conversion of the Principal Amount or Accrued Interest require registration or listing with or approval of any Governmental Authority, stock exchange or other regulatory body under any federal or state law or regulation or otherwise before such shares may be validly issued or delivered upon conversion, the Company shall, at its sole cost and expense, in good faith and as expeditiously as possible, secure such registration, listing or approval, as the case may be.

3J(2)Antitrust Notification.  If the Holder determines, in its sole judgment upon the advice of counsel, that the conversion of all or any portion of the Principal Amount or Accrued Interest pursuant to the terms hereof would be subject to the provisions of the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the “HSR Act”), the Company shall file as soon as practicable after the date on which the Company receives notice from the Holder of the applicability of the HSR Act and a request to so file with the United States Federal Trade Commission (the “FTC”) and the United States Department of Justice (the “DOJ”) the notification and report form required to be filed by it pursuant to the HSR Act in connection with such conversion (and in any event the Company shall make such filing no later than seven (7) Business Days after the date on which the Holder filed with the FTC and DOJ the notification and report form required to be filed by the Holder pursuant to the HSR Act in connection with such conversion).  Any such notification and report form will be in full compliance with the requirements of the HSR Act.  The Company will furnish to the Holder and the Holder shall furnish to the Company promptly (but in no event more than five (5) Business Days after receipt of a reasonable request therefore) such information and assistance as the other party may reasonably request in connection with the preparation of any filing or submission required to be filed by the Holder or the Company under the HSR Act.  The Company and the Holder shall respond promptly after receiving any inquiries or requests for additional information from the FTC or the DOJ during the HSR waiting period.  Each party shall keep the other apprised periodically and at the other party’s request of the status of any communications with, and any inquiries or requests for additional information from, the FTC or the DOJ.  The Holder shall bear all filing or other fees required to be paid by the Company and the Holder (or the “ultimate parent entity” of the Holder, if any) under the HSR Act or any other applicable law in connection with such filings and all costs and expenses (including, without limitation, reasonable attorneys’ fees and expenses) incurred by the Company and the Holder in connection with the preparation of such filings and responses to inquiries or requests.  In the event that this paragraph 3J(2) is applicable to any conversion of all or any portion of the Principal Amount or Accrued Interest, the acquisition by the Holder of the Note Shares subject to such conversion shall be subject to the expiration or earlier termination of the waiting period under the HSR Act (with the Principal Conversion Date or the Accrued Interest Conversion Date being deemed to be the date immediately following the date of such expiration or early termination).

3KLimitation on Beneficial Ownership.  Notwithstanding anything to the contrary contained herein, the Holder shall not be entitled to receive Equity Interests of the Company (i) upon conversion of this Note (in whole or in part) into the Company’s Common Stock in accordance with paragraph 3A, or (ii) upon the Company’s conversion of all or any portion of the Accrued Interest into the Company’s Common Stock in accordance with paragraphs 2B and 3B, in each case to the extent (but only to the extent) that such conversion or receipt would cause the Holder Group to become, directly or indirectly, a “beneficial owner” (within the meaning of Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder) of a number of Equity Interests of a class that is registered under 

the Exchange Act which exceeds the Maximum Percentage of the Equity Interests of such class that are outstanding at such time.  This limitation on beneficial ownership (a) may be increased, decreased or terminated, in the Holder’s sole discretion, upon sixty-one (61) days’ notice to the Company by the Holder and (b) shall terminate automatically on the date that is fifteen (15) days' prior to the Maturity Date.  Any purported delivery of Equity Interests in connection with the occurrence of either of clauses (i) or (ii) above prior to the termination of this restriction in accordance herewith shall be void and have no effect to the extent (but only to the extent) that such delivery would result in the Holder Group becoming the beneficial owner of more than the Maximum Percentage of the Equity Interests of a class that is registered under the Exchange Act that is outstanding at such time.  If any delivery of Equity Interests owed to the Holder following the occurrence of either of clauses (i) or (ii) above is not made, in whole or in part, as a result of this limitation, the Company’s obligation to make such delivery shall not be extinguished and the Company shall deliver such Equity Interests as promptly as practicable after the Holder gives notice to the Company that such delivery would not result in such limitation being triggered or upon termination of the restriction in accordance with the terms hereof.  To the extent limitations contained in this paragraph 3K apply, the determination of whether this Note is convertible and of which portion of this Note is convertible shall be the sole responsibility and in the sole determination of the Holder and the submission of a Conversion Notice shall be deemed to constitute the Holder's determination that the issuance of the full number of Note Shares requested in the Conversion Notice is permitted hereunder, and the Company shall not have any obligation to verify or confirm the accuracy of such determination.  For any reason at any time, upon written or oral request of the Holder, the Company shall, within one (1) Trading Day of such request, confirm orally and in writing to the Holder the number of Equity Interests of any class then outstanding, it being understood that the Holder may rely on such confirmation from the Company for purposes of the Holder’s determination referenced in the preceding sentence. The provisions of this paragraph 3K shall be construed, corrected and implemented in a manner so as to effectuate the intended beneficial ownership limitation herein contained.

FIBROCELL SCIENCE, INC.

COMMON STOCK PURCHASE WARRANT

Fibrocell Science, Inc., a Delaware corporation (together with any corporation which shall succeed to or assume the obligations of Fibrocell Science, Inc. hereunder, the “Company”), hereby certifies that, for value received, [___________________] (the “Holder”), or its assigns, is entitled, subject to the terms set forth below, to purchase from the Company at any time during the Exercise Period (as defined in Section 12 hereof) up to [______________] fully paid and non-assessable shares of Common Stock (as defined in Section 12 hereof), at a purchase price per share equal to the Exercise Price (as defined in Section 12 hereof).  The number of shares of Common Stock for which this Common Stock Purchase Warrant (this “Warrant”) is exercisable and the Exercise Price are subject to adjustment as provided herein.

1.    DEFINITIONS.  Certain terms are used in this Warrant as specifically defined in Section 12 hereof. 

2.    EXERCISE OF WARRANT.

2.1.    Exercise.  This Warrant may be exercised prior to its expiration pursuant to Section 2.5 hereof by the Holder at any time or from time to time during the Exercise Period, by submitting the form of subscription attached hereto (the “Exercise Notice”) duly executed by the Holder, to the Company at its principal office, indicating whether the Holder is electing to purchase a specified number of shares by paying the Aggregate Exercise Price as provided in Section 2.2 or is electing to exercise this Warrant as to a specified number of shares pursuant to the net exercise provisions of Section 2.3.  On or before the first Trading Day following the date on which the Company has received the Exercise Notice, the Company shall transmit by facsimile or electronic mail an acknowledgement of confirmation of receipt of the Exercise Notice.  Subject to Section 2.4, this Warrant shall be deemed exercised for all purposes as of the close of business on the day on which the Holder has delivered the Exercise Notice to the Company.  The Aggregate Exercise Price, if any, shall be paid by wire transfer to the Company within two (2) Business Days of the date of exercise and prior to the time the Company issues the certificates evidencing the shares issuable upon such exercise.  In the event this Warrant is not exercised in full, the Company may, at its expense, require the Holder, after such partial exercise, to promptly return this Warrant to the Company and the Company will forthwith issue and deliver to or upon the order of the Holder a new Warrant or Warrants of like tenor, in the name of the Holder or as the Holder (upon payment by the Holder of any applicable transfer taxes) may request, calling in the aggregate on the face or faces thereof for the number of shares of Common Stock equal (without 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 (without giving effect to any adjustment therein) for which this Warrant shall have been exercised.

2.2.    Payment of Exercise Price by Wire Transfer.   If the Holder elects to purchase a specified number of shares by paying the Aggregate Exercise Price, the Holder shall pay such amount by wire transfer of immediately available funds to the account designated by the Company in its acknowledgement of receipt of such Exercise Notice pursuant to Section 2.1 hereof.

2.3.    Net Exercise.  The Holder may also elect to exercise this Warrant at any time or from time to time, by receiving shares of Common Stock equal to the number of shares determined pursuant to the following formula:

X  =   Y (A - B)
            A
where,
		
	X =
	the number of shares of Common Stock to be issued to Holder;

		
	Y =
	the number of shares of Common Stock as to which this Warrant is to be exercised (as indicated on the Exercise Notice);

		
	A =
	the volume weighted average price of the Common Stock quoted on the Nasdaq Capital Market or any other U.S. exchange on which the Common Stock is listed, whichever is applicable, as posted by Bloomberg L.P. (or such other reference reasonably relied upon by the Company if not so published) for the Trading Day immediately preceding the date of exercise; and 

		
	B =
	the Exercise Price.

2.4.    Antitrust Notification.  If the Holder determines, in its sole judgment upon the advice of counsel, that an exercise of this Warrant pursuant to the terms hereof would be subject to the provisions of the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the “HSR Act”), the Company shall file as soon as practicable after the date on which the Company receives notice from the Holder of the applicability of the HSR Act and a request to so file with the United States Federal Trade Commission (the “FTC”) and the United States Department of Justice (the “DOJ”) the notification and report form required to be filed by it pursuant to the HSR Act in connection with the exercise of this Warrant (and in any event the Company shall make such filing no later than seven (7) Business Days after the date on which the Holder filed with the FTC and DOJ the notification and report form required to be filed by the Holder  pursuant to the HSR Act in connection with the exercise of this Warrant).  Any such notification and report form will be in full compliance with the requirements of the HSR Act.  The Company will furnish to the Holder and the Holder shall furnish to the Company promptly (but in no event more than five (5) Business Days after receipt of a reasonable request therefore) such information and assistance as the other party may reasonably request in connection with the preparation of any filing or submission required to be filed by the Holder or the Company under the HSR Act.  The Company and the Holder shall respond promptly after receiving any inquiries or requests for additional information from the FTC or the DOJ during the HSR waiting period.  Each party shall keep the other apprised periodically and at the other party’s request of the status of any communications with, and any inquiries or requests for additional information from, the FTC or the DOJ.  The Holder shall bear all filing or other fees required to be paid by the Company and the Holder (or the “ultimate parent entity” of the Holder, if any) under the HSR Act or any other applicable law in connection with such filings and all costs and expenses (including, without limitation, reasonable attorneys’ fees and expenses) incurred by the Company and the Holder in connection with the preparation of such filings and responses to inquiries or requests.  In the event that this Section 2.4 is applicable to any exercise of this Warrant, the purchase by the Holder of the Exercise Shares subject to such exercise, and the payment by the Holder of the Exercise Price therefor, shall be subject to the expiration or earlier termination of the waiting period under the HSR Act (with the exercise date of this Warrant being deemed to be the date immediately following the date of such expiration or early termination).  

2.5.    Termination.  This Warrant shall terminate upon the earlier to occur of (i) exercise in full or (ii) the expiration of the Exercise Period.

3.    REGISTRATION RIGHTS.  The Holder of this Warrant has certain rights to require the Company to register its resale of the Warrant Shares under the Securities Act and any blue sky or securities laws of any jurisdictions within the United States at the time and in the manner specified in the Registration Rights Agreement, dated as of September 7, 2016, as amended and in effect from time to time.

4.    DELIVERY OF STOCK CERTIFICATES ON EXERCISE.  

4.1.    Delivery of Exercise Shares.  As soon as practicable after any exercise of this Warrant and in any event within three (3) Trading Days thereafter (such date, the “Exercise Share Delivery Date”), the Company shall, at its expense (including the payment by it of any applicable issue or stamp taxes), cause to be issued in the name of and delivered to the Holder, or as the Holder may direct, a certificate or certificates evidencing the number of fully paid and nonassessable shares of Common Stock (which number shall be rounded down to the nearest whole share in the event any fractional share may otherwise be issuable upon such exercise and the Company shall pay a cash adjustment to the Holder in respect of such final fraction in an amount equal to such fraction multiplied by the Exercise Price) to which the Holder shall be entitled on such exercise, in such denominations as may be requested by the Holder, which certificate or certificates shall be free of restrictive and trading legends (except for any such legends as may be required under the Securities Act).  In lieu of delivering physical certificates for the shares of Common Stock issuable upon any exercise of this Warrant, provided the Company’s transfer agent is participating in the Depository Trust Company (“DTC”) Fast Automated Securities Transfer program or a similar program, upon request of the Holder, the Company shall cause its transfer agent to electronically transmit such shares of Common Stock issuable upon exercise of this Warrant to the Holder (or its designee), by crediting the account of the Holder’s (or such designee’s) broker with DTC through its Deposit Withdrawal Agent Commission system (provided that the same time periods herein as for stock certificates shall apply) as instructed by the Holder (or its designee).  

4.2.    Compensation for Buy-In on Failure to Timely Deliver Exercise Shares. In addition to any other rights available to the Holder, if the Company fails to cause its transfer agent to transmit to the Holder Exercise Shares pursuant to an exercise on or before the Exercise Share Delivery Date, and if after such date the Holder is required by its broker 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 Exercise Shares which the Holder anticipated receiving upon such exercise (a “Buy-In”), then the Company shall (A) pay in cash to the Holder the amount, if any, by which (x) the 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 Exercise Shares that the Company was required to deliver to the 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 Holder, either reinstate the portion of the Warrant and equivalent number of Exercise Shares for which such exercise was not honored (in which case such exercise shall be deemed rescinded) or deliver to the Holder the number of shares of Common Stock that would have been issued had the Company timely complied with its exercise and delivery obligations hereunder. For example, if the Holder purchases Common Stock having a total purchase price of $11,000 to cover a Buy-In with respect to an attempted exercise of 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 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 evidence of the amount of such loss. Nothing herein shall limit a Holder’s right to pursue a decree of specific performance and/or injunctive relief with respect to the Company’s failure to timely deliver shares of Common Stock upon exercise of the Warrant as required pursuant to the terms hereof.

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

5.    ADJUSTMENT FOR DIVIDENDS, DISTRIBUTIONS AND RECLASSIFICATIONS.

5.1.    Distribution of Assets; Spin-Off.  If the Company shall declare or make any dividend or other distribution of its assets (or rights to acquire its assets) to holders of Common Stock, by way of return of capital or otherwise (including, without limitation, any distribution of cash, stock or other securities, property or options by way of a Spin-Off, dividend, reclassification, corporate rearrangement or other similar transaction, but excluding stock 

dividends or stock split adjustments in respect of which are provided for in Section 7 hereof) (a “Distribution”), at any time after the issuance of this Warrant, then, in each such case:

(a)    (i) the Exercise Price in effect immediately prior to the close of business on the record date fixed for the determination of holders of Common Stock entitled to receive the Distribution shall be reduced, effective as of the close of business on such record date, to a price determined by multiplying such Exercise Price by a fraction of which:

(A)    the numerator shall be the Market Price of the Common Stock on the Trading Day immediately preceding such record date minus the Fair Market Value of the Distribution applicable to one share of Common Stock, and 

(B)    the denominator shall be the Market Price of the Common Stock on the Trading Day immediately preceding such record date; and

(b)    In the event of a Spin-Off in which the Distribution is of common stock of a subsidiary of the Company, then (i) the Exercise Price in effect immediately prior to the close of business on the record date fixed for the determination of holders of Common Stock entitled to receive such Distribution shall be reduced, effective as of the close of business on such record date, to a price determined by multiplying such Exercise Price by a fraction of which:

(A)    the numerator shall be the Market Price of the Common Stock on the Trading Day immediately preceding such record date minus the Fair Market Value of the Distribution applicable to one share of Common Stock, and 

(B)    the denominator shall be the Market Price of the Common Stock on the Trading Day immediately preceding such record date; 

and (ii) the Holder shall receive an additional warrant to purchase common stock of such company, the terms of which shall be identical to those of this Warrant (and expiring the same date), except that such warrant shall be exercisable into the number of shares of common stock of such company that would have been issuable or distributed to the Holder of this Warrant pursuant to the Distribution had the Holder exercised this Warrant for cash for the full number of shares of Common Stock remaining available under this Warrant immediately prior to such record date and with an aggregate exercise price equal to the aggregate amount by which the Exercise Price of this Warrant was decreased with respect to the Distribution pursuant to the terms of the preceding clause (i) of this Section 5.1(b).

5.2.  Other Events.  If any event occurs of the type contemplated by the provisions of this Section 5 but not expressly provided for by such provisions, then the Company’s board of directors (the “Board of Directors”), acting in good faith and consistent with their fiduciary duties, shall make an appropriate adjustment in the Exercise Price and the number of shares of Common Stock obtainable upon exercise of this Warrant so as to protect the rights of the Holder.

		
	6.
	ADJUSTMENT FOR REORGANIZATION, CONSOLIDATION, MERGER, ETC.

6.1.  Certain Adjustments.  In case at any time or from time to time, the Company shall (i) effect a capital reorganization, reclassification or recapitalization, (ii) consolidate or merge with or into any other person, or (iii) transfer all or substantially all of its properties or assets to any other person under any plan or arrangement contemplating the dissolution of the Company, then in each such case, this Warrant shall thereafter be exercisable for the same kind and amounts of securities (including shares of stock) or other assets, or both, which were issuable or distributable to the holders of outstanding Common Stock upon such reorganization, reclassification, recapitalization, consolidation, merger or transfer, in respect of that number of shares of Common Stock for which this Warrant could have been exercised immediately prior to such reorganization, reclassification, recapitalization, consolidation, merger or transfer; and, in any such case, appropriate adjustments (as determined in good faith by the Board of Directors) shall be made 

to assure that the provisions set forth herein shall thereafter be applicable, as nearly as reasonably may be practicable, in relation to any securities or other assets thereafter deliverable upon the exercise of this Warrant.

6.2.  Continuation of Terms.  Upon any reorganization, consolidation, merger or transfer (and any dissolution following any transfer) referred to in this Section 6, this Warrant shall continue in full force and effect and the terms hereof shall be applicable to the shares of stock and other securities and property receivable on the exercise of this Warrant after the consummation of such reorganization, consolidation or merger or the effective date of dissolution following any such transfer, as the case may be, and shall be binding upon the issuer of any such stock or other securities, including, in the case of any such transfer, the person acquiring all or substantially all of the properties or assets of the Company, whether or not such person shall have expressly assumed the terms of this Warrant.

7.    ADJUSTMENTS FOR STOCK EVENTS AND Subsequent Rights Offerings.  

7.1.    General.  If at any time there shall occur any stock split, stock dividend, reverse stock split or other subdivision of the Company’s Common Stock (“Stock Event”), then the number of shares of Common Stock remaining issuable upon exercise of this Warrant shall be appropriately adjusted such that the proportion of the number of shares issuable hereunder to the total number of shares of the Company prior to such Stock Event is equal to the proportion of the number of shares issuable hereunder after such Stock Event to the total number of shares of the Company after such Stock Event.  The Exercise Price shall be proportionately decreased or increased upon the occurrence of any Stock Event; provided that in no event will the Exercise Price be less than the par value of the Common Stock.

7.2.    Subsequent Rights Offerings.  If at any time the Company grants any rights to purchase stock warrants or other securities pro rata to the holders of shares of Common Stock (“Purchase Rights”), then in each such event provision shall be made so that the Holder shall receive upon exercise hereof and upon the terms applicable to such Purchase Rights, the aggregate Purchase Rights which the Holder would have been entitled to receive had this Warrant been exercised on the date of such event and, in any such case, appropriate adjustments (as determined in good faith by the Board of Directors) shall be made to assure that the provisions set forth herein shall thereafter be applicable, as nearly as reasonably may be practicable, in relation to any securities or other assets thereafter deliverable upon the exercise of this Warrant.

8.    NO IMPAIRMENT.  The Company will not, by amendment of its Certificate of Incorporation or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of this Warrant, but will at all times in good faith assist in the carrying out of all such terms and in taking all such action as may be necessary or appropriate in order to protect the rights of the Holder against impairment.  Without limiting the generality of the foregoing, the Company (i) will not increase the par value of any shares of Common Stock receivable on the exercise of this Warrant above the amount payable therefor on such exercise and (ii) will 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 shares of stock on the exercise of this Warrant from time to time outstanding.  

9.    CERTIFICATE AS TO ADJUSTMENTS.  In each case of any event that requires any adjustment pursuant to Sections 5, 6, or 7 hereof, the Company at its expense will promptly prepare a certificate setting forth such adjustment, and showing, in detail, the facts upon which any such adjustment is based, including a statement of (i) the number of shares of Common Stock then issued and outstanding, and (ii) the number of shares of Common Stock to be received upon exercise of this Warrant, in effect immediately prior to such adjustment and as adjusted on account thereof.  The Company will forthwith mail a copy of each such certificate to the Holder, and will, on the written request at any time of the Holder, furnish to the Holder a like certificate setting forth the calculations used to determine such adjustment.

10.    NOTICES OF RECORD DATE.  In the event of:

(a)    any taking by the Company of a record 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 any right to subscribe for, purchase or otherwise acquire any shares of stock of any class or any other securities or property, or to receive any other right; or

(b)    any capital reorganization of the Company, any reclassification or recapitalization of the capital stock of the Company or any transfer of all or substantially all the assets of the Company to or any consolidation or merger of the Company with or into any other Person or any other Change of Control; or

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

then, and in each such event, the Company will mail or cause to be mailed to the Holder a notice specifying (i) the date on which any such 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 date on which any such reorganization, reclassification, recapitalization, transfer, consolidation, merger, dissolution, liquidation or winding-up is anticipated to take place, and the time, if any is to be fixed, as of which the holders of record of Common Stock shall be entitled to exchange their shares of Common Stock for securities or other property deliverable on such reorganization, reclassification, recapitalization, transfer, consolidation, merger, dissolution, liquidation or winding-up.  Such notice shall be mailed at least fifteen (15) days prior to the date specified in such notice on which any such action is to be taken.

11.    RESERVATION OF STOCK ISSUABLE ON EXERCISE OF WARRANT; REGULATORY COMPLIANCE.  

11.1.    Reservation of Stock Issuable on Exercise of Warrant.  The Company shall at all times while this Warrant shall be outstanding, reserve and keep available out of its authorized but unissued Common Stock, such number of shares of Common Stock as shall from time to time be sufficient to effect the exercise of all or any portion of the Warrant Shares (disregarding for this purpose any and all limitations of any kind on such exercise).  The Company shall, from time to time in accordance with the Delaware General Corporation Law, increase the authorized number of shares of Common Stock or take other effective action if at any time the unissued number of authorized shares shall not be sufficient to satisfy the Company’s obligations under this Section 11.  

11.2.    Regulatory Compliance. If any shares of Common Stock to be reserved for the purpose of exercise of the Warrant Shares require registration or listing with or approval of any Governmental Authority, stock exchange or other regulatory body under any federal or state law or regulation or otherwise before such shares may be validly issued or delivered upon exercise, the Company shall, at its sole cost and expense, in good faith and as expeditiously as possible, secure such registration, listing or approval, as the case may be.

13.    LIMITATION ON BENEFICIAL OWNERSHIP.  Notwithstanding anything to the contrary contained herein, the Holder shall not be entitled to receive shares of Common Stock or other securities (together with Common Stock, “Equity Interests”) upon exercise of this Warrant to the extent (but only to the extent) that such exercise or receipt would cause the Holder Group to become, directly or indirectly, a “beneficial owner” (within the meaning of Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder) of a number of Equity Interests of a class that is registered under the Exchange Act which exceeds the Maximum Percentage (as defined below) of the Equity Interests of such class that are outstanding at such time.  This limitation on beneficial ownership (a) may be increased, decreased or terminated, in the Holder’s sole discretion, upon 61 days’ written notice to the Company by the Holder and (b) shall terminate automatically on the date that is 15 days prior to expiration of the Exercise Period.  Any purported delivery of Equity Interests in connection with the exercise of the Warrant prior to the termination of this restriction in accordance herewith shall be void and have no effect to the extent (but only to the extent) that such delivery would result in the Holder Group becoming the beneficial owner of more than the Maximum Percentage of 

the Equity Interests of a class that is registered under the Exchange Act that is outstanding at such time. If any delivery of Equity Interests owed to the Holder following exercise of this Warrant is not made, in whole or in part, as a result of this limitation, the Company’s obligation to make such delivery shall not be extinguished and the Company shall deliver such Equity Interests as promptly as practicable after the Holder gives notice to the Company that such delivery would not result in such limitation being triggered or upon termination of the restriction in accordance with the terms hereof.  To the extent limitations contained in this Section 13 apply, the determination of whether this Warrant is exercisable and of which portion of this Warrant is exercisable shall be the sole responsibility and in the sole determination of the Holder, and the submission of an Exercise Notice shall be deemed to constitute the Holder’s determination that the issuance of the full number of Warrant Shares requested in the Exercise Notice is permitted hereunder, and neither the Company nor any Warrant agent shall have any obligation to verify or confirm the accuracy of such determination.  For purposes of this Section 13, (i) the term “Maximum Percentage” shall mean 4.99%; provided, that if at any time after the date hereof the Holder Group beneficially owns in excess of 4.99% of any class of Equity Interests in the Company that is registered under the Exchange Act (excluding any Equity Interests deemed beneficially owned by virtue of this Warrant and the Note), then the Maximum Percentage shall automatically increase to 9.99% so long as the Holder Group owns in excess of 4.99% of such class of Equity Interests (and shall, for the avoidance of doubt, automatically decrease to 4.99% upon the Holder Group ceasing to own in excess of 4.99% of such class of Equity Interests); and (ii) the term “Holder Group” shall mean the Holder plus any other Person with which the Holder is considered to be part of a group under Section 13 of the Exchange Act or with which the Holder otherwise files reports under Sections 13 and/or 16 of the Exchange Act.  In determining the number of Equity Interests of a particular class outstanding at any point in time, the Holder may rely on the number of outstanding Equity Interests of such class as reflected in (x) the Company’s most recent Annual Report on Form 10-K or Quarterly Report on Form 10-Q filed with the Securities and Exchange Commission, as the case may be, (y) a more recent public announcement by the Company or (z) a more recent notice by the Company or its transfer agent to the Holder setting forth the number of Equity Interests of such class then outstanding.  For any reason at any time, upon written or oral request of the Holder, the Company shall, within one (1) Trading Day of such request, confirm orally and in writing to the Holder the number of Equity Interests of any class then outstanding. The provisions of this Section 13 shall be construed, corrected and implemented in a manner so as to effectuate the intended beneficial ownership limitation herein contained.  The limitations in this Section 13 shall not have an effect on any calculation or payment due to the Holder of this Warrant pursuant to Section 14 hereof.

14.    CHANGE OF CONTROL.  Within three (3) Business Days of the occurrence of a Change of Control, the Company shall provide written notice to the Holder indicating that a Change of Control occurred (the “Change of Control Notice”).  During the period of thirty (30) days following the receipt of the Change of Control Notice, the Holder may, by giving written notice to the Company, require the Company to repurchase all of this Warrant at the option value of this Warrant using Black-Scholes calculation methods and making the assumptions described in the Black-Scholes methodology described in Exhibit A.  The fact that this Warrant may be exercised on a cashless net exercise basis as provided in Section 2.3 shall not have any effect on any calculation or payment due to the Holder of this Warrant pursuant to this Section 14.  The limitations in Section 13 hereof shall not have an effect on any calculation or payment due to the Holder of this Warrant pursuant to this Section 14.

15.    REGISTRATION AND TRANSFER OF WARRANT.
 
15.1.    Registration of Warrant.  The Company shall register and record transfers, exchanges, reissuances and cancellations of this Warrant, upon the records to be maintained by the Company for that purpose, in the name of the record Holder hereof from time to time.  The Company may deem and treat the registered Holder of this Warrant as the absolute owner hereof for the purpose of any exercise hereof or any distribution to the Holder, and for all other purposes, absent actual notice to the contrary.  The Company shall be entitled to rely, and held harmless in acting or refraining from acting in reliance upon, any notices, instructions or documents it believes in good faith to be from an authorized representative of the Holder.

15.2    Transferability.  This Warrant and all rights hereunder (including, without limitation, any registration rights) are transferable, in whole or in part, upon surrender of this Warrant at the principal office of the Company or its designated agent, together with a written assignment of this Warrant substantially in the form of assignment (the “Assignment Notice”) attached hereto duly executed by the Holder or its agent or attorney. Upon such surrender, the 

Company shall execute and deliver a new Warrant or Warrants in the name of the assignee or assignees, as applicable, and in the denomination or denominations specified in such Assignment Notice, and shall issue to the assignor a new Warrant evidencing the portion of this Warrant not so assigned, and this Warrant shall promptly be cancelled. This Warrant, if properly assigned in accordance herewith, may be exercised by a new holder for the purchase of Exercise Shares without having a new Warrant issued.

15.3.    New Warrants. This Warrant may be divided or combined with other Warrants upon presentation hereof at the aforesaid office of the Company, together with a written notice specifying the names and denominations in which new Warrants are to be issued, signed by the Holder or its agent or attorney. Subject to compliance with Section 15.2, as to any transfer which may be involved in such division or combination, the Company shall execute and deliver a new Warrant or Warrants in exchange for this Warrant or Warrants to be divided or combined in accordance with such notice. All Warrants issued on transfers or exchanges shall be dated the original Issue Date and shall be identical with this Warrant except as to the number of Exercise Shares issuable pursuant thereto.

16.    LOSS, THEFT, DESTRUCTION OR MUTILATION OF WARRANT. The Company covenants that upon receipt by the Company of evidence reasonably satisfactory to it of the loss, theft, destruction or mutilation of this Warrant or any stock certificate relating to the Exercise Shares, and in case of loss, theft or destruction, of indemnity or security reasonably satisfactory to it (which, in the case of this Warrant, shall not include the posting of any bond), and upon surrender and cancellation of such Warrant or stock certificate, if mutilated, the Company will make and deliver a new Warrant or stock certificate of like tenor and dated as of such cancellation, in lieu of such Warrant or stock certificate.

17.    REMEDIES.  The Company stipulates that the remedies at law of the Holder in the event of any default or threatened default by the Company in the performance of or compliance with any of the terms of this Warrant are not and will not be adequate, and that such terms may be specifically enforced by a decree for the specific performance of any agreement contained herein or by an injunction against a violation of any of the terms hereof or otherwise.  NO PARTY HEREUNDER SHALL BE LIABLE UNDER THIS WARRANT, THE NOTE OR THE REGISTRATION RIGHTS AGREEMENT TO ANY OTHER PERSON FOR ANY INDIRECT, INCIDENTAL, CONSEQUENTIAL, RELIANCE OR SPECIAL DAMAGES (AS OPPOSED TO ACTUAL OR DIRECT DAMAGES) SUFFERED BY ANY OTHER PERSON (INCLUDING DAMAGES FOR HARM TO BUSINESS, LOST REVENUES, LOST SAVINGS OR LOST PROFITS SUFFERED BY SUCH PERSON), WHETHER IN CONTRACT, WARRANTY, STRICT LIABILITY, TORT OR OTHERWISE, INCLUDING NEGLIGENCE OF ANY KIND, WHETHER ACTIVE OR PASSIVE, AND REGARDLESS OF WHETHER THE POSSIBILITY THAT SUCH DAMAGES COULD RESULT WAS KNOWN.

18.    NO RIGHTS AS A STOCKHOLDER.  Except as otherwise specifically provided herein, the Holder, solely in such Person’s capacity as a holder of this Warrant, shall not be entitled to vote or receive dividends or be deemed the holder of share capital of the Company for any purpose, nor shall anything contained in this Warrant be construed to confer upon the Holder, solely in such Person’s capacity as the Holder of this Warrant, any of the rights of a stockholder of the Company or any right to vote, give or withhold consent to any corporate action (whether any reorganization, issue of stock, reclassification of stock, consolidation, merger, conveyance or otherwise), receive notice of meetings, receive dividends or subscription rights, or otherwise, prior to the issuance to the Holder of the Exercise Shares.  

19.    NOTICES.  All notices, requests, demands and other communications that are required or may be given pursuant to the terms of this Warrant shall be in writing and shall be deemed delivered (i) on the date of delivery when delivered by hand on a Business Day during normal business hours or, if delivered on a day that is not a Business Day or after normal business hours, then on the next Business Day, (ii) on the date of transmission when sent by facsimile transmission or email during normal business hours on a Business Day with telephone confirmation of receipt or, if transmitted on a day that is not a Business Day or after normal business hours, then on the next Business Day, or (iii) on the second Business Day after the date of dispatch when sent by a reputable courier service that maintains records of receipt; provided, however, that, in any such case, such communication is addressed, if to the Holder, as specified for such communications on Exhibit A to the Note, and if to the Company, as follows, or, in each case, to such other address as the Company or the Holder may designate in a written notice to the other pursuant to this Section 19:

if to the Company, to:

20.    CONSENT TO AMENDMENTS.  Any term of this Warrant may be amended, and the Company may take any action herein prohibited, or compliance therewith may be waived, only if the Company shall have obtained the written consent (and not without such written consent) to such amendment, action or waiver from the Holder; provided, that if any other holder of the Warrants receives any remuneration or compensation as consideration for any such amendment, consent or waiver, then such remuneration or compensation shall be concurrently delivered ratably to all Holders of then outstanding Warrants, on the same equivalent terms.  No course of dealing between the Company and the Holder nor any delay in exercising any rights hereunder shall operate as a waiver of any rights of the Holder.

21.    MISCELLANEOUS.  In case any provision of this Warrant shall be invalid, illegal or unenforceable, or partially invalid, illegal or unenforceable, the provision shall be enforced to the extent, if any, that it may legally be enforced and the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby.  If any provision of this Warrant is found to conflict with the Purchase Agreement, the provisions of this Warrant shall prevail.  If any provision of this Warrant is found to conflict with the Note, the provisions of the Note shall prevail.  THIS WARRANT SHALL BE CONSTRUED AND ENFORCED IN ACCORDANCE WITH, AND THE RIGHTS OF THE PARTIES SHALL BE GOVERNED BY, THE INTERNAL LAW OF THE STATE OF NEW YORK, EXCLUDING CHOICE-OF-LAW PRINCIPLES OF THE LAW OF SUCH STATE THAT WOULD PERMIT THE APPLICATION OF THE LAWS OF A JURISDICTION OTHER THAN SUCH STATE.  The headings in this Warrant are for purposes of reference only, and shall not limit or otherwise affect any of the terms hereof.

EXHIBIT A 

Black-Scholes Assumptions

	
		
	Underlying 
Security Price:
	The volume weighted average price of the Common Stock quoted on the Nasdaq Capital Market or any other U.S. exchange on which the Common Stock is listed, whichever is applicable, as posted by Bloomberg L.P. (or such other reference reasonably relied upon by the Company if not so published) for the thirty (30) Trading Days ending on the Trading Day immediately preceding the date of the Preliminary Change of Control (the “Reference Date”).

	Exercise Price:
	The Exercise Price as adjusted and then in effect for the Warrant.

	Dividend Rate:
	The Company’s annualized dividend yield as of the Reference Date.

	Interest Rate:
	The applicable U.S. treasury note risk free rate as of the Reference Date and for a term equal to the remaining term of the Warrant.

	Model Type:
	Black-Scholes

	Exercise Type:
	American

	Put or Call:
	Call

	Trade Date:
	The Reference Date

	Expiration Date:
	The expiration of the Exercise Period

	Settle Date:
	The Reference Date plus one Trading Day

	Exercise Delay:
	0

	Volatility:
	The 30-day average of the daily volatility (annualized) over the period beginning on and including the Reference Date and ending on the date that is the thirtieth (30) Trading Day prior to the Reference Date, for the Common Stock as obtained from the HVT function on Bloomberg.

Such valuation of the Warrant based on the Black-Scholes methodology shall not be discounted in any way. If the Holder disputes such Black-Scholes valuation pursuant to this Exhibit A as calculated by the Company, the Company and the Holder will choose a mutually-agreeable firm to compute the valuation of the Warrant using the guidelines above, and such valuation shall be final. The fees and expenses of such firm shall be borne by the party whose calculation of the Black-Scholes value is the greatest variance to the mutually-agreed firm’s calculation.  In the event that a new warrant is issued by a company in a Spin-Off from the Company pursuant to Section 5.1(b) of the Warrant, references in this Exhibit A to such spun-off company’s “Dividend Rate” and “Volatility” shall refer those of the Company unless at the time of such measurement, such spun-off company has been trading in the public markets for at least 6 months.
