Delivery of Stock Certificates, Etc., on Exercise.  The Company agrees that the shares of Common Stock purchased upon exercise of this Warrant shall be deemed to be issued to the Holder as the record owner of such shares as of the close of business on the date on which the Exercise Notice is received, this Warrant shall have been surrendered and payment made for such shares in accordance herewith.  As soon as practicable after the exercise of this Warrant in full or in part, and in any event within five (5) business days thereafter, the Company at its expense (including the payment by it of any applicable issue taxes) will cause to be issued in the name of and delivered to the Holder, or as the Holder (upon payment by the Holder of any applicable transfer taxes) may direct in compliance with applicable securities laws, a certificate or certificates for the number of duly and validly issued, fully paid and non-assessable shares of Common Stock (or Other Securities) to which the Holder shall be entitled on such exercise, plus, in lieu of any fractional share to which the Holder would otherwise be entitled, cash equal to such fraction multiplied by the then Fair Market Value of one full share, together with any other stock or other securities and property (including cash, where applicable) to which the Holder is entitled upon such exercise pursuant to Section 1 or otherwise.

2.2

Exercise.

(a)

Payment may be made either (i) in cash by wire transfer of immediately available funds or by certified or official bank check payable to the order of the Company equal to the applicable aggregate Exercise Price, (ii) by delivery of shares of Common Stock and/or Common Stock issuable upon exercise of this Warrant in accordance with the formula set forth in subsection (b) below, or (iii) by a combination of any of the foregoing methods, for the number of shares of Common Stock specified in such Exercise Notice (as such exercise number shall be adjusted to reflect any adjustment in the total number of shares of Common Stock issuable to the Holder per the terms of this Warrant) and the Holder shall thereupon be entitled to receive the number of duly authorized, validly issued, fully-paid and non-assessable shares of Common Stock (or Other Securities) determined as provided herein.

(b)

Notwithstanding any provisions herein to the contrary, if the Fair Market Value of one share of Common Stock is greater than the Exercise Price (at the date of calculation as set forth below), in lieu of exercising this Warrant for cash, the Holder may elect to receive shares equal to the value (as determined below) of this Warrant (or the portion thereof being exercised) by surrender of this Warrant at the principal office of the Company together with the properly endorsed Exercise Notice in which event the Company shall issue to the Holder a number of shares of Common Stock computed using the following formula:

	X=

	Y(A-B)

	 
	 	A

	 

	Where X =

	the number of shares of Common Stock to be issued to the Holder

	Y =

	the number of shares of Common Stock purchasable under this Warrant or, if only a portion of this Warrant is being exercised, the portion of this Warrant being exercised (at the date of such calculation)

	A =

	the Fair Market Value of one share of the Company’s Common Stock (at the date of such calculation)

	B =

	the Exercise Price per share (as adjusted to the date of such calculation)

3.

Effect of Reorganization, Etc.; Adjustment of Exercise Price.

3.1

Reorganization, Consolidation, Merger, Etc.  If there occurs any capital reorganization or any reclassification of the Common Stock of the Company, the consolidation or merger of the Company with or into another person (other than a merger or consolidation of the Company in which the Company is the continuing entity and which does not result in any reorganization or reclassification of its outstanding Common Stock) or the sale or conveyance of all or substantially all of the assets of the Company to another person, then, as a condition precedent to any such reorganization, reclassification, consolidation, merger, sale or conveyance, the Holder will be entitled to receive upon surrender of this Warrant to the Company (x) to the extent there are cash proceeds distributed to holders of Common Stock following the consummation of such reorganization, reclassification, consolidation, merger, sale or conveyance, in exchange for such Warrant, cash in an amount equal to the cash proceeds that would have been payable to the Holder had the Holder exercised such Warrant immediately prior to the consummation of such reorganization, reclassification, consolidation, merger, sale or conveyance, less the aggregate Exercise Price payable upon exercise of this Warrant, and (y) to the extent that the Holder would be entitled to receive Common stock (or Other Securities) (in addition to or in lieu of cash in connection with any such reorganization, reclassification, consolidation, merger, sale or conveyance), the same kind and amounts of securities or other assets, or both, that are issuable or distributable to the holders of outstanding Common Stock (or Other Securities) of the Company with respect to their Common Stock (or Other Securities) upon such reorganization, reclassification, consolidation, merger, sale or conveyance, as would have been deliverable to the Holder had the Holder exercised such Warrant immediately prior to the consummation of such reorganization, reclassification, consolidation, merger, sale or conveyance less an amount of such securities having a value equal to the aggregate Exercise Price payable upon exercise of this Warrant.

3.2

Dissolution.  In the event of any dissolution of the Company following the transfer of all or substantially all of its properties or assets, the Company, concurrently with any distributions made to holders of its Common Stock, shall at its expense deliver or cause to be delivered to the Holder the stock and other securities and property (including cash, where applicable) receivable by the Holder pursuant to Section 3.1, or, if the Holder shall so instruct the Company, to a bank or trust company specified by the Holder and having its principal office in New York, NY as trustee for the Holder (the “Trustee”).

Continuation of Terms.  Upon any reorganization, consolidation, merger or transfer in which cash proceeds (and any dissolution following any transfer) referred to in this Section 3 are distributed, either (i) in the event that this Warrant continues in full force and effect, the terms of this Warrant 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,

3.3

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 as provided in Section 4 or (ii) in the event this Warrant does not continue in full force and effect after the consummation of the transactions described in this Section 3, then the Company’s securities and property (including cash, where applicable) receivable by the Holder will be delivered to the Holder under Section 3.1 or the Trustee as contemplated by Section 3.2.

4.

Extraordinary Events Regarding Common Stock.  In the event that the Company shall (a) issue additional shares of the Common Stock as a dividend or other distribution on outstanding Common Stock or any preferred stock issued by the Company, (b) subdivide its outstanding shares of Common Stock, (c) combine its outstanding shares of the Common Stock into a smaller number of shares of the Common Stock, then, in each such event, the number of shares of Common Stock that the Holder shall thereafter, on the exercise hereof as provided in Section 1, be entitled to receive shall be adjusted to a number determined by multiplying the number of shares of Common Stock that would otherwise (but for the provisions of this Section 4) be issuable on such exercise by a fraction of which (a) the numerator is the number of issued and outstanding shares of Common Stock immediately after such Event, and (b) the denominator is the number of issued and outstanding shares of Common Stock immediately prior to such Event.

5.

Certificate as to Adjustments.  In each case of any adjustment or readjustment in the shares of Common Stock (or Other Securities) issuable on the exercise of this Warrant, the Company at its expense will promptly cause its Chief Financial Officer or other appropriate designee to compute such adjustment or readjustment in accordance with the terms of this Warrant and prepare a certificate setting forth such adjustment or readjustment and showing in detail the facts upon which such adjustment or readjustment is based, including a statement of (a) the consideration received or receivable by the Company for any additional shares of Common Stock (or Other Securities) issued or sold or deemed to have been issued or sold, (b) the number of shares of Common Stock (or Other Securities) outstanding or deemed to be outstanding, and (c) the Exercise Price and the number of shares of Common Stock to be received upon exercise of this Warrant, in effect immediately prior to such adjustment or readjustment and as adjusted or readjusted as provided in this Warrant.  The Company will forthwith mail a copy of each such certificate to the Holder and any warrant agent of the Company (appointed pursuant to Section 11 hereof).

6.

Reservation of Stock, Etc., Issuable on Exercise of Warrant.  The Company will at all times reserve and keep available, solely for issuance and delivery on the exercise of this Warrant, shares of Common Stock (or Other Securities) from time to time issuable on the exercise of this Warrant.

7.

Assignment; Exchange of Warrant.  Subject to compliance with applicable securities laws, this Warrant, and the rights evidenced hereby, may be transferred by any registered holder hereof (a “Transferor”) in whole or in part.  On the surrender for exchange of this Warrant, with the Transferor’s endorsement in the form of Exhibit B attached hereto (the “Transferor Endorsement Form”) and together with evidence reasonably satisfactory to the Company demonstrating compliance with applicable securities laws, which shall include, without limitation, a legal opinion from the Transferor’s counsel (at the Company’s expense) that provides that such transfer is exempt from the registration requirements of applicable securities laws, the Company at its expense (but with payment by the Transferor of any applicable transfer taxes) will issue and deliver to or on the order of the Transferor thereof a new Warrant of like tenor, in the name of the Transferor and/or the transferee(s) specified in such Transferor Endorsement Form (each a “Transferee”), calling in the aggregate on the face or faces thereof for the number of shares of Common Stock called for on the face or faces of this Warrant so surrendered by the Transferor.

8.

Replacement of Warrant.  On receipt of evidence reasonably satisfactory to the Company of the loss, theft, destruction or mutilation of this Warrant and, in the case of any such loss, theft or destruction of this Warrant, on delivery of an indemnity agreement or security reasonably satisfactory in form and amount to the Company or, in the case of any such mutilation, on surrender and cancellation of this Warrant, the Company at its expense will execute and deliver, in lieu thereof, a new Warrant of like tenor.

9.

Intentionally Omitted.

10.

Maximum Exercise.  Notwithstanding anything herein to the contrary, in no event shall the Holder be entitled to exercise any portion of this Warrant in excess of that portion of this Warrant upon exercise of which the sum of (1) the number of shares of Common Stock beneficially owned by the Holder and its Affiliates (other than shares of Common Stock which may be deemed beneficially owned through the ownership of the unexercised portion of this Warrant or the unexercised or unconverted portion of any other security of the Holder subject to a limitation on conversion analogous to the limitations contained herein) and (2) the number of shares of Common Stock issuable upon the exercise of the portion of this Warrant with respect to which the determination of this proviso is being made, would result in beneficial ownership by the Holder and its Affiliates of any amount greater than 9.99% of the then outstanding shares of Common Stock (whether or not, at the time of such exercise, the Holder and its Affiliates beneficially own more than 9.99% of the then outstanding shares of Common Stock). As used herein, the term “Affiliate” means any person or entity that, directly or indirectly through one or more intermediaries, controls or is controlled by or is under common control with a person or entity, as such terms are used in and construed under Rule 144 under the Securities Act of 1933, as amended.  For purposes of the second preceding sentence, beneficial ownership shall be determined in accordance with Section 13(d) of the Securities Exchange Act of 1934, as amended, and Regulations 13D-G thereunder, except as otherwise provided in clause (1) of such sentence. For any reason at any time, upon written or oral request of the Holder, the Company shall within one (1) business day confirm orally and in writing to the Holder the number of shares of Common Stock outstanding as of any given date.  The limitations set forth herein (x) shall automatically become null and void following notice to the Company upon the occurrence and during the continuance of an Event of Default (as defined in the Security Agreement) and (y) may be waived by the Holder upon provision of no less than sixty-one (61) days prior written notice to the Company; provided, however, that, such written notice of waiver shall only be effective to the extent that no indebtedness (including principal, interest, fees and charges) of the Company to the Holder or any of its Affiliates is outstanding.  Notwithstanding the foregoing, at no time shall the Company be obligated to issue any shares of Common Stock pursuant to the terms of this Warrant, the Security Agreement, any Ancillary Agreement (as defined in the Security Agreement) or any other applicable agreement if the issuance of such shares of Common Stock would exceed the aggregate number of shares of Common Stock which the Company may issue pursuant to the terms of this Warrant, the Security Agreement, any Ancillary Agreement or any other applicable agreement without violating the rules or regulations of the Principal Market (the “Exchange Cap”), except that such limitation shall not apply in the event that the Company obtains the approval of its stockholders as required by the applicable rules or regulations of the Principal Market for issuances of Common Stock in excess of such amount.

11.

Warrant Agent.  The Company may, by written notice to the Holder of this Warrant, appoint an agent for the purpose of issuing Common Stock (or Other Securities) on the exercise of this Warrant pursuant to Section 1, exchanging this Warrant pursuant to Section 7, and replacing this Warrant pursuant to Section 8, or any of the foregoing, and thereafter any such issuance, exchange or replacement, as the case may be, shall be made at such office by such agent.

12.

Transfer on the Company’s Books.  Until this Warrant is transferred on the books of the Company, the Company may treat the registered holder hereof as the absolute owner hereof for all purposes, notwithstanding any notice to the contrary.

13.

Rights of Shareholders.  The Holder shall not be entitled to vote or receive dividends or be deemed the holder of the shares of Common Stock or any other securities of the Company which may at any time be issuable upon exercise of this Warrant for any purpose (the “Warrant Shares”), nor shall anything contained herein be construed to confer upon the Holder, as such, any of the rights of a shareholder of the Company or any right to vote for the election of directors or upon any matter submitted to shareholders at any meeting thereof, or to give or withhold consent to any corporate action (whether upon the recapitalization, issuance of shares, reclassification of shares, change of nominal value, consolidation, merger, conveyance or otherwise) or to receive notice of meetings, or to receive dividends or subscription rights or otherwise, in each case, until the earlier to occur of (x) the date of actual delivery to Holder (or its designee) of the Warrant Shares issuable upon the exercise hereof or (y) the fifth business day following the date such Warrant Shares first become deliverable to Holder, as provided herein.

14.

Notices, Etc.  All notices and other communications from the Company to the Holder shall be mailed by first class registered or certified mail, postage prepaid, at such address as may have been furnished to the Company in writing by the Holder from time to time.

15.

Miscellaneous.  This Warrant and any term hereof may be changed, waived, discharged or terminated only by an instrument in writing signed by the party against which enforcement of such change, waiver, discharge or termination is sought. THIS WARRANT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO PRINCIPLES OF CONFLICTS OF LAWS.  ANY ACTION BROUGHT CONCERNING THE TRANSACTIONS CONTEMPLATED BY THIS WARRANT SHALL BE BROUGHT ONLY IN THE STATE COURTS OF NEW YORK OR IN THE FEDERAL COURTS LOCATED IN THE STATE OF NEW YORK; PROVIDED, HOWEVER, THAT THE HOLDER MAY CHOOSE TO WAIVE THIS PROVISION AND BRING AN ACTION OUTSIDE THE STATE OF NEW YORK.  The individuals executing this Warrant on behalf of the Company agree to submit to the jurisdiction of such courts and waive trial by jury.  The prevailing party shall be entitled to recover from the other party its reasonable attorneys’ fees and costs.  In the event that any provision of this Warrant is invalid or unenforceable under any applicable statute or rule of law, then such provision shall be deemed inoperative to the extent that it may conflict therewith and shall be deemed modified to conform with such statute or rule of law.  Any such provision which may prove invalid or unenforceable under any law shall not affect the validity or enforceability of any other provision of this Warrant.  The headings in this Warrant are for purposes of reference only, and shall not limit or otherwise affect any of the terms hereof.  The invalidity or unenforceability of any provision hereof shall in no way affect the validity or enforceability of any other provision hereof.  The Company acknowledges that legal counsel participated in the preparation of this Warrant and, therefore, stipulates that the rule of construction that ambiguities are to be resolved against the drafting party shall not be applied in the interpretation of this Warrant to favor any party against the other party.
