2. BUYER’S REPRESENTATIONS AND WARRANTIES.

Each Buyer, severally and not jointly, represents and warrants to the Company with respect to only itself that, as of the date hereof and as of each Closing Date:

(a)Investment Purpose. The Buyer is acquiring the Securities for its own account for investment only and not with a view towards, or for resale in connection with, the public sale or distribution thereof, except pursuant to sales registered or exempted under the Securities Act; provided, however, that by making the representations herein, such Buyer reserves the right to dispose of the Securities at any time in accordance with or pursuant to an effective registration statement covering such Securities or an available exemption under the Securities Act. Such Buyer does not presently have any agreement or understanding, directly or indirectly, with any Person to distribute any of the Securities.

(b)Accredited Investor Status. The Buyer is an “Accredited Investor” as that term is defined in Rule 501(a)(3) of Regulation D.

(c)Reliance on Exemptions. The Buyer understands that the Securities are being offered and sold to it in reliance on specific exemptions from the registration requirements of United States federal and state securities laws and that the Company is relying in part upon the truth and accuracy of, and such Buyer’s compliance with, the representations, warranties, agreements, acknowledgments and understandings of such Buyer set forth herein in order to determine the availability of such exemptions and the eligibility of such Buyer to acquire the Securities.

(d)Information. The Buyer and its advisors (and his or, its counsel), if any, have been furnished with all materials relating to the business, finances and operations of the Company and information he deemed material to making an informed investment decision

2

regarding his purchase of the Securities, which have been requested by such Buyer. The Buyer and its advisors, if any, have been afforded the opportunity to ask questions of the Company and its management. Neither such inquiries nor any other due diligence investigations conducted by such Buyer or its advisors, if any, or its representatives shall modify, amend or affect such Buyer’s right to rely on the Company’s representations and warranties contained in Section 3 below. The Buyer understands that its investment in the Securities involves a high degree of risk. The Buyer has sought such accounting, legal and tax advice, as it has considered necessary to make an informed investment decision with respect to its acquisition of the Securities.

(e)Transfer or Resale. The Buyer understands that: (i) the Securities have not been registered under the Securities Act or any state securities laws, and may not be offered for sale, sold, assigned or transferred unless (A) subsequently registered thereunder, (B) such Buyer shall have delivered to the Company an opinion of counsel, in a generally acceptable form, to the effect that such Securities to be sold, assigned or transferred may be sold, assigned or transferred pursuant to an exemption from such registration requirements, or (C) such Buyer provides the Company with reasonable assurances (in the form of seller and broker representation letters) that such Securities can be sold, assigned or transferred pursuant to Rule 144 promulgated under the Securities Act, as amended (or a successor rule thereto) (collectively, “Rule 144”), in each case following the applicable holding period set forth therein; and (ii) any sale of the Securities made in reliance on Rule 144 may be made only in accordance with the terms of Rule 144 and further, if Rule 144 is not applicable, any resale of the Securities under circumstances in which the seller (or the person through whom the sale is made) may be deemed to be an underwriter (as that term is defined in the Securities Act) may require compliance with some other exemption under the Securities Act or the rules and regulations of the SEC thereunder.

(f)Legends. The Buyer agrees to the imprinting, so long as its required by this Section 2(f), of a restrictive legend on the Securities in substantially the following form:

THE SECURITIES REPRESENTED BY THIS CERTIFICATE [AND THOSE SECURITIES INTO WHICH THEY ARE CONVERTIBLE] HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR APPLICABLE STATE SECURITIES LAWS. THE SECURITIES [AND THOSE SECURITIES INTO WHICH THEY ARE CONVERTIBLE] HAVE BEEN ACQUIRED SOLELY FOR INVESTMENT PURPOSES AND NOT WITH A VIEW TOWARD RESALE AND MAY NOT BE OFFERED FOR SALE, SOLD, TRANSFERRED OR ASSIGNED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT FOR THE SECURITIES UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR APPLICABLE STATE SECURITIES LAWS, OR AN OPINION OF COUNSEL, IN A GENERALLY ACCEPTABLE FORM, THAT REGISTRATION IS NOT REQUIRED UNDER SAID ACT OR APPLICABLE STATE SECURITIES LAWS.

3

Certificates evidencing the Conversion Shares shall not contain any legend (including the legend set forth above), (i) while a registration statement covering the resale of such security is effective under the Securities Act, (ii) following any sale of such Conversion Shares pursuant to an effective registration statement under the Securities Act or pursuant to Rule 144, or (iii) if such legend is not required under applicable requirements of the Securities Act (including judicial interpretations and pronouncements issued by the staff of the SEC). The Buyer agrees that the removal of restrictive legend from certificates representing Securities as set forth in this Section 3(f) is predicated upon the Company’s reliance that the buyer will sell any Securities pursuant to either the registration requirements of the Securities Act, including any applicable prospectus delivery requirements, or an exemption therefrom, and that if Securities are sold pursuant to a registration statement, they will be sold in compliance with the plan of distribution set forth therein.

(g)Organization; Authority. Such Buyer is an entity duly organized, validly existing and in good standing under the laws of the jurisdiction of its organization with the requisite power and authority to enter into and to consummate the transactions contemplated by the Transaction Documents (as defined below) to which it is a party and otherwise to carry out its obligations hereunder and thereunder.

(h)Authorization, Enforcement. This Agreement has been duly and validly authorized, executed and delivered on behalf of such Buyer and shall constitute the legal, valid and binding obligations of such Buyer enforceable against such Buyer in accordance with its terms, except as such enforceability may be limited by general principles of equity or to applicable bankruptcy, insolvency, reorganization, moratorium, liquidation and other similar laws relating to, or affecting generally, the enforcement of applicable creditors' rights and remedies.

(i)No Conflicts. The execution, delivery and performance by such Buyer of this Agreement and the consummation by such Buyer of the transactions contemplated hereby will not (i) result in a violation of the organizational documents of such Buyer, (ii) conflict with, or constitute a default (or an event which with notice or lapse of time or both would become a default) under, or give to others any rights of termination, amendment, acceleration or cancellation of, any agreement, indenture or instrument to which such Buyer is a party or (iii) result in a violation of any law, rule, regulation, order, judgment or decree (including federal and state securities laws) applicable to such Buyer, except, in the case of clauses (ii) and (iii) above, for such conflicts, defaults, rights or violations which could not, individually or in the aggregate, reasonably be expected to have a material adverse effect on the ability of such Buyer to perform its obligations hereunder.

The Buyer has not directly or indirectly, nor has any Person acting on behalf of or pursuant to any understanding with the Buyer, engaged in any transactions in the securities of the Company (including, without limitation, any Short Sales (as defined below) involving the Company's securities) during the period commencing as of the time that the Buyer first contacted the Company or the Company's agents regarding the specific investment in the Company contemplated by this Agreement and ending

The Company further represents to each Buyer that the Company's decision to enter into the Transaction Documents to which it is a party has been based solely on the independent evaluation by the Company and its representatives.

(g)No Integrated Offering. None of the Company, its Subsidiaries or any of their affiliates, nor any Person acting on their behalf has, directly or indirectly, made any offers or sales of any security or solicited any offers to buy any security, under circumstances that would cause this offering of the Securities to require approval of stockholders of the Company under any applicable stockholder approval provisions, including, without limitation, under the rules and regulations of any exchange or automated quotation system on which any of the securities of the Company are listed or designated for quotation. None of the Company, its Subsidiaries, their affiliates nor any Person acting on their behalf will take any action or steps that would cause the offering of any of the Securities to be integrated with other offerings of securities of the Company.

(h)Dilutive Effect. The Company understands and acknowledges that the number of Conversion Shares will increase in certain circumstances.

During the two (2) years prior to the date hereof, the Company has timely filed all reports, schedules, forms, proxy statements, statements and other documents required to be filed by it with the SEC pursuant to the reporting requirements of the Securities Exchange Act of 1934, as amended (the “1934 Act”) (all of the foregoing filed prior to the date hereof and filed after the Closing Date disclosing definitive agreements of the Company in transactions that do not constitute a Material Adverse Effect, and all exhibits and appendices included therein and financial statements, notes and

8

schedules thereto and documents incorporated by reference therein being hereinafter referred to as the “SEC Documents”). The Company has delivered or has made available to the Buyers or their respective representatives true, correct and complete copies of each of the SEC Documents not available on the EDGAR system. As of their respective dates, the SEC Documents complied in all material respects with the requirements of the 1934 Act and the rules and regulations of the SEC promulgated thereunder applicable to the SEC Documents, and none of the SEC Documents, at the time they were filed with the SEC, contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. As of their respective dates, the financial statements of the Company included in the SEC Documents (the “Financial Statements”) complied in all material respects with applicable accounting requirements and the published rules and regulations of the SEC with respect thereto as in effect as of the time of filing. Such financial statements have been prepared in accordance with generally accepted accounting principles (“GAAP”), consistently applied, during the periods involved (except (i) as may be otherwise indicated in such financial statements or the notes thereto, or (ii) in the case of unaudited interim statements, to the extent they may exclude footnotes or may be condensed or summary statements) and fairly present in all material respects the financial position of the Company as of the dates thereof and the results of its operations and cash flows for the periods then ended (subject, in the case of unaudited statements, to normal year-end audit adjustments which will not be material, either individually or in the aggregate). The Company is not currently contemplating amending or restating any of the Financial Statements (including, without limitation, any notes or any letter of the independent accountants of the Company with respect thereto) included in the SEC Documents, nor has the Company been informed by its independent accountants that they recommend that the Company amend or restate any of the Financial Statements. The Company has engaged an approved audit form to audit the consolidated financial results for the Company and its subsidiaries.

(k)Absence of Certain Changes. Since the date of the Company's most recent audited financial statements contained in a Form 10-K, there has been no Material Adverse Effect, nor any event or occurrence specifically affecting the Company or its Subsidiaries that would be reasonably expected to result in a Material Adverse Effect. Since the date of the Company's most recent audited financial statements contained in a Form 10-K, neither the Company nor any of its Subsidiaries has (i) declared or paid any dividends, (ii) sold any material assets, individually or in the aggregate, outside of the ordinary course of business or (iii) made any material capital expenditures, individually or in the aggregate, outside of the ordinary course of business.

(l)No Undisclosed Events, Liabilities, Developments or Circumstances. No event, liability, development or circumstance has occurred or exists, or is reasonably expected to

9

exist or occur specific to the Company, any of its Subsidiaries or any of their respective businesses, properties, liabilities, prospects, operations (including results thereof) or condition (financial or otherwise), that has not been publicly disclosed and would reasonably be expected to have a Material Adverse Effect.

(m)Conduct of Business; Regulatory Permits. Neither the Company nor any of its Subsidiaries is in violation of any term under its Articles of Incorporation, any certificate of designation, preferences or rights of any other outstanding series of preferred stock of the Company or any of its Subsidiaries or Bylaws or their organizational charter, certificate of formation, memorandum of association, articles of association, Articles of Incorporation or certificate of incorporation or bylaws, respectively.

Without limiting the generality of the foregoing, the Company is not in violation of any of the rules, regulations or requirements of the Principal Market and has no knowledge of any facts or circumstances that could reasonably lead to delisting or suspension of the Common Shares by the Principal Market in the foreseeable future. During the one year prior to the date hereof, (i) the Common Shares have been listed or designated for quotation on the Principal Market, (ii) trading in the Common Shares has not been suspended by the SEC or the Principal Market and (iii) the Company has received no communication, written or oral, from the SEC or the Principal Market regarding the suspension or delisting of the Common Shares from the Principal Market, which has not been publicly disclosed. The Company and each of its Subsidiaries possess all certificates, authorizations and permits issued by the appropriate regulatory authorities necessary to conduct their respective businesses, except where the failure to possess such certificates, authorizations or permits would not reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect, and neither the Company nor any of its Subsidiaries has received any notice of proceedings relating to the revocation or modification of any such certificate, authorization or permit. There is no agreement, commitment, judgment, injunction, order or decree binding upon the Company or any of its Subsidiaries or to which the Company or any of its Subsidiaries is a party which has or would reasonably be expected to have the effect of prohibiting or materially impairing any business practice of the Company or any of its Subsidiaries, any acquisition of property by the Company or any of its Subsidiaries or the conduct of business by the Company or any of its Subsidiaries as currently conducted other than such effects, individually or in the aggregate, which have not had and would not reasonably be expected to have a Material Adverse Effect on the Company or any of its Subsidiaries.

(r)Manipulation of Price. Neither the Company nor any of its Subsidiaries has, and, to the knowledge of the Company, no Person acting on their behalf has, directly or indirectly, taken any action designed to cause or to result in the stabilization or manipulation of the price of any security of the Company or any of its Subsidiaries to facilitate the sale or resale of any of the Securities.

All disclosure provided or made available to the Buyers regarding the Company and its Subsidiaries, their businesses and the transactions contemplated hereby, including the schedules to this Agreement, furnished by or on behalf of the Company or any of its Subsidiaries, taken as a whole, is true and correct and does not contain any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements made therein, in the light of the circumstances under which they were made, not misleading.

(w)No General Solicitation.

13

as an issuer required to file reports under the 1934 Act even if the 1934 Act or the rules and regulations thereunder would no longer require or otherwise permit such termination.

(b)Use of Proceeds. Neither the Company nor any Subsidiary will, directly or indirectly, use the proceeds of the transactions contemplated herein to repay any loans to any executives or employees of the Company. Neither the Company nor any Subsidiary will, directly or indirectly, use the proceeds of the transactions contemplated herein, or lend, contribute, facilitate or otherwise make available such proceeds to any Person (i) to fund, either directly or indirectly, any activities or business of or with any Person that is identified on the list of Specially Designated Nationals and Blocker Persons maintained by OFAC, or in any country or territory, that, at the time of such funding, is, or whose government is, the subject of Sanctions Programs, or (ii) in any other manner that will result in a violation of Sanctions Programs.

(c)Listing. To the extent applicable, the Company shall promptly secure the listing or designation for quotation (as the case may be) of all of the Underlying Securities (as defined below) upon each national securities exchange and automated quotation system, if any, upon which the Common Shares are then listed or designated for quotation (as the case may be, each an “Eligible Market”), subject to official notice of issuance, and shall use reasonable efforts to maintain such listing or designation for quotation (as the case may be) of all Underlying Securities from time to time issuable under the terms of the Transaction Documents on such Eligible Market for the Reporting Period. Neither the Company nor any of its Subsidiaries shall take any action which could be reasonably expected to result in the delisting or suspension of the Common Shares on an Eligible Market during the Reporting Period. The Company shall pay all fees and expenses in connection with satisfying its obligations under this Section 4(c). “Underlying Securities” means the (i) the Conversion Shares, (ii) the Warrant Shares, and (iii) any Common Shares issued or issuable with respect to the Conversion Shares or Warrant Shares, including, without limitation, (1) as a result of any stock split, stock dividend, recapitalization, exchange or similar event or otherwise and (2) shares of capital stock of the Company into which the Common Shares are converted or exchanged without regard to any limitations on conversion of the Convertible Debentures or exercise of the Warrants.

(d)Fees. The Company shall pay to YA Global II SPV, LLC, an affiliate of the lead Buyer (the “Subsidiary Fund”), a structuring fee (the “Structuring Fee”) in the amount of $15,000, of which $5,000 has been paid, and the balance shall be deducted from the gross proceeds of the Closing. The Company authorizes each Buyer to deduct any such fees due hereunder from the gross process of the purchase of any Convertible Debentures.

(e)Pledge of Securities. Notwithstanding anything to the contrary contained in this Agreement, the Company acknowledges and agrees that, subject to compliance with applicable federal and state securities laws, the Securities may be pledged by a Buyer in connection with a bona fide margin agreement or other loan or financing arrangement that is secured by the Securities. The Company hereby agrees to execute and deliver such documentation as a pledgee of the Securities may reasonably request in connection with a pledge of the Securities to such pledgee by a Buyer.

14

(f)Disclosure of Transactions and Other Material Information. On or before 9:30 a.m., New York time, on the fourth (4th) Business Day (as used herein “Business Day” means any day other than a Saturday, Sunday or other day on which commercial banks in New York, New York are authorized or required by law to remain closed) after the date of this Agreement, the Company shall file a Current Report on Form 8-K describing all the material terms of the transactions contemplated by the Transaction Documents in the form required by the 1934 Act and attaching all the material Transaction Documents (including, without limitation, this Agreement (including all attachments, the “8-K Filing”). From and after the filing of the 8-K Filing, the Company shall have disclosed all material, non-public information (if any) provided to any of the Buyers by the Company or any of its Subsidiaries or any of their respective officers, directors, employees or agents in connection with the transactions contemplated by the Transaction Documents. In addition, effective upon the filing of the 8-K Filing, the Company acknowledges and agrees that any and all confidentiality or similar obligations with respect to the transactions contemplated by the Transaction Documents under any agreement, whether written or oral, between the Company, any of its Subsidiaries or any of their respective officers, directors, affiliates, employees or agents, on the one hand, and any of the Buyers or any of their affiliates, on the other hand, shall terminate. The Company shall not, and the Company shall cause each of its Subsidiaries and each of its and their respective officers, directors, employees and agents not to, provide any Buyer with any material, non-public information regarding the Company or any of its Subsidiaries from and after the date hereof except pursuant a specific request by such Buyer.

(g)Reservation of Shares. So long as any of the Convertible Debentures remain outstanding, the Company shall take all action necessary to at all times have authorized, and reserved for the purpose of issuance, no less than 300% of the maximum number of shares of Common Shares issuable upon conversion of all the Convertible Debentures then outstanding (assuming for purposes hereof that (x) the Convertible Debentures are convertible at the Market Conversion Price (as defined therein) then in effect, and (y) any such conversion shall not take into account any limitations on the conversion of the Convertible Debentures), and 100% of the Warrant Shares (the “Required Reserve Amount”); provided that at no time shall the number of Common Shares reserved pursuant to this Section 4(g) be reduced other than proportionally in connection with any conversion and/or redemption, or reverse stock split. If at any time the number of shares of Common Shares authorized and reserved for issuance is not sufficient to meet the Required Reserved Amount, the Company will promptly take all corporate action necessary to authorize and reserve a sufficient number of shares, including, without limitation, calling a special meeting of stockholders to authorize additional shares to meet the Company's obligations pursuant to the Transaction Documents, in the case of an insufficient number of authorized shares, and recommending that stockholders vote in favor of an increase in such authorized number of shares sufficient to meet the Required Reserved Amount.

Beginning on the date hereof and ending on the date three months following the date that the Convertible Debentures have been fully repaid, the Company shall not issue any securities, preferred shares, notes, loans, or other instruments which are convertible, exercisable, or exchangeable into Common Shares at a price that varies with the market price or can periodically be reset. For the sake of clarity, the Company shall remain free to participate in any non-variable rate equity or convertible debt financing transaction.

15

(i)Piggy-Back Registrations. If at any time there is not an effective registration statement covering the Securities and the Company shall determine to prepare and file with the SEC a registration statement relating to an offering for its own account or the account of others under the Securities Act of any of its equity securities, other than on Form S-4 or Form S-8 (each as promulgated under the Securities Act) or their then equivalents relating to equity securities to be issued solely in connection with any acquisition of any entity or business or equity securities issuable in connection with the stock option or other employee benefit plans, then the Company shall send to each Buyer a written notice of such determination and, if within fifteen (15) days after the date of such notice, any such Buyer shall so request in writing, the Company shall include in such registration statement all or any part of such Securities such Buyer requests to be registered.

(j)Conduct of Business. The business of the Company and its Subsidiaries shall not be conducted in violation of any law, ordinance or regulation of any Governmental Entity, except where such violations would not reasonably be expected to result, either individually or in the aggregate, in a Material Adverse Effect.

(k)No Short Sales. The Buyer hereby agrees that it shall not directly or indirectly, engage in any Short Sales involving the Company’s securities during the period commencing on the date hereof and ending five months after the date when no Convertible Debentures remain outstanding. "Short Sales" means all "short sales" as defined in Rule 200 promulgated under Regulation SHO under the 1934 Act (as defined below), whether or not against the box, and forward sale contracts, options, puts, calls, “put equivalent positions” (as defined in Rule 16a-1(h) under the 1934 Act) and similar arrangements, and sales and other transactions through non-U.S. broker dealers or foreign regulated brokers.

5. REGISTER; TRANSFER AGENT INSTRUCTIONS; LEGEND.

(a)Register. The Company shall maintain at its principal executive offices or with the Transfer Agent (or at such other office or agency of the Company as it may designate by notice to each holder of Securities), a register for the Convertible Debentures and the Warrants in which the Company shall record the name and address of the Person in whose name the Convertible Debentures and Warrants have been issued (including the name and address of each transferee), the amount of Convertible Debentures and Warrants held by such Person, and the number of Conversion Shares issuable upon conversion of the Convertible Debentures held by such Person and Warrants Shares issuable upon exercise of the Warrants held by such Person. The Company shall keep the register open and available at all times during business hours for inspection of any Buyer or its legal representatives.

(b)Transfer Restrictions. The Securities may only be disposed of in compliance with state and federal securities laws. In connection with any transfer of Securities other than pursuant to an effective registration statement or Rule 144, to the Company or to an Affiliate of a Buyer or in connection with a pledge as contemplated herein, the Company may require the transferor thereof to provide to the Company an opinion of counsel selected by the transferor and reasonably acceptable to the Company, the form and substance of which opinion shall be reasonably satisfactory to the Company, to the effect that such transfer does not require

16

registration of such transferred Securities under the Securities Act. As a condition of transfer, any such transferee shall agree in writing to be bound by the terms of this Agreement and shall have the rights and obligations of a Buyer under this Agreement.

(a)Governing Law; Jurisdiction; Jury Trial. All questions concerning the construction, validity, enforcement and interpretation of this Agreement shall be governed by the internal laws of the State of New York, without giving effect to any choice of law or conflict of law provision or rule (whether of the State of New York or any other jurisdictions) that would cause the application of the laws of any jurisdictions other than the State of New York. Each party hereby irrevocably waives personal service of process and consents to process being served in any such suit, action or proceeding by mailing a copy thereof to such party at the address for such notices to it under this Agreement and agrees that such service shall constitute good and sufficient service of process and notice thereof. Nothing contained herein shall be deemed to limit in any way any right to serve process in any manner permitted by law. Nothing contained herein shall be deemed or operate to preclude any Buyer from bringing suit or taking other legal action against the Company in any other jurisdiction to collect on the Company's obligations to such Buyer or to enforce a judgment or other court ruling in favor of such Buyer. EACH PARTY HEREBY IRREVOCABLY WAIVES ANY RIGHT IT MAY HAVE TO, AND AGREES NOT TO REQUEST, A JURY TRIAL FOR

THE ADJUDICATION OF ANY DISPUTE HEREUNDER OR UNDER ANY OTHER TRANSACTION DOCUMENT OR IN CONNECTION WITH OR ARISING OUT OF THIS AGREEMENT, ANY OTHER TRANSACTION DOCUMENT OR ANY TRANSACTION CONTEMPLATED HEREBY OR THEREBY.

(b)Counterparts. This Agreement may be executed in two or more identical counterparts, all of which shall be considered one and the same agreement and shall become effective when counterparts have been signed by each party and delivered to the other party. In the event that any signature is delivered by facsimile transmission or by an e-mail which contains a portable document format (.pdf) file of an executed signature page, such signature page shall create a valid and binding obligation of the party executing (or on whose behalf such signature is executed) with the same force and effect as if such signature page were an original thereof.

(c)Headings; Gender. The headings of this Agreement are for convenience of reference and shall not form part of, or affect the interpretation of, this Agreement.

The terms "including," "includes," "include" and words of like import shall be construed broadly as if followed by the words "without limitation." The terms "herein," "hereunder," "hereof" and words of like import refer to this entire Agreement instead of just the provision in which they are found.

(d)Entire Agreement, Amendments. This Agreement supersedes all other prior oral or written agreements between the Buyer, the Company, their affiliates and persons acting on their behalf with respect to the matters discussed herein, and this Agreement and the instruments referenced herein contain the entire understanding of the parties with respect to the matters covered herein and therein and, except as specifically set forth herein or therein, neither the Company nor any Buyer makes any representation, warranty, covenant or undertaking with respect to such matters.

(i)In consideration of each Buyer's execution and delivery of the Transaction Documents and acquiring the Securities thereunder and in addition to all of the Company's other obligations under the Transaction Documents, the Company shall defend, protect, indemnify and hold harmless each Buyer and each of their stockholders, partners, members, officers, directors, employees and any of the foregoing Persons' agents or other representatives (including, without limitation, those retained in connection with the transactions

21

contemplated by this Agreement) (collectively, the "Indemnitees") from and against any and all actions, causes of action, suits, claims, losses, costs, penalties, fees, liabilities and damages, and expenses in connection therewith (irrespective of whether any such Indemnitee is a party to the action for which indemnification hereunder is sought), and including reasonable attorneys' fees and disbursements (the "Indemnified Liabilities"), incurred by any Indemnitee as a result of, or arising out of, or relating to (i) any misrepresentation or breach of any representation or warranty made by the Company in any of the Transaction Documents, (ii) any breach of any covenant, agreement or obligation of the Company or any Subsidiary contained in any of the Transaction Documents or (iii) any cause of action, suit, proceeding or claim brought or made against such Indemnitee by a third party (including for these purposes a derivative action brought on behalf of the Company or any Subsidiary) or which otherwise involves such Indemnitee, in each instance that arises out of or results from (A) the execution, delivery, performance or enforcement of any of the Transaction Documents, (B) any transaction financed or to be financed in whole or in part, directly or indirectly, with the proceeds of the issuance of the Securities, or (C) any disclosure properly made by such Buyer pursuant to Section 4(f). To the extent that the foregoing undertaking by the Company may be unenforceable for any reason, the Company shall make the maximum contribution to the payment and satisfaction of each of the Indemnified Liabilities which is permissible under applicable law.

(ii)Promptly after receipt by an Indemnitee under this Section 9(g) of notice of the commencement of any action or proceeding (including any governmental action or proceeding) involving an Indemnified Liability, such Indemnitee shall, if a claim in respect thereof is to be made against the Company under this Section 9(g), deliver to the Company a written notice of the commencement thereof, and the Company shall have the right to participate in, and, to the extent the Company so desires, to assume control of the defense thereof with counsel mutually reasonably satisfactory to the Company and the Indemnitee; provided, however, that an Indemnitee shall have the right to retain its own counsel with the fees and expenses of such counsel to be paid by the Company if: (A) the Company has agreed in writing to pay such fees and expenses; (B) the Company shall have failed promptly to assume the defense of such Indemnified Liability and to employ counsel reasonably satisfactory to such Indemnitee in any such Indemnified Liability; or (C) the named parties to any such Indemnified Liability (including any impleaded parties) include both such Indemnitee and the Company, and such Indemnitee shall have been advised by counsel that a conflict of interest is likely to exist if the same counsel were to represent such Indemnitee and the Company (in which case, if such Indemnitee notifies the Company in writing that it elects to employ separate counsel at the expense of the Company, then the Company shall not have the right to assume the defense thereof and such counsel shall be at the expense of the Company), provided further, that in the case of clause (C) above the Company shall not be responsible for the reasonable fees and expenses of more than one (1) separate legal counsel for the Indemnitees. The Indemnitee shall reasonably cooperate with the Company in connection with any negotiation or defense of any such action or Indemnified Liability by the Company and shall furnish to the Company all information reasonably available to the Indemnitee which relates to such action or Indemnified Liability. The Company shall keep the Indemnitee reasonably apprised at all times as to the status of the defense or any settlement negotiations with respect thereto. The Company shall not be liable for any settlement of any action, claim or proceeding effected without its prior written consent, provided, however, that the Company shall not unreasonably withhold, delay or condition its consent. The Company shall not, without the prior written consent of the

22

Indemnitee, consent to entry of any judgment or enter into any settlement or other compromise which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnitee of a release from all liability in respect to such Indemnified Liability or litigation, and such settlement shall not include any admission as to fault on the part of the Indemnitee. Following indemnification as provided for hereunder, the Company shall be subrogated to all rights of the Indemnitee with respect to all third parties, firms or corporations relating to the matter for which indemnification has been made. The failure to deliver written notice to the Company within a reasonable time of the commencement of any such action shall not relieve the Company of any liability to the Indemnitee under this Section 9(g), except to the extent that the Company is materially and adversely prejudiced in its ability to defend such action.

(iii)The indemnification required by this Section 9(g) shall be made by periodic payments of the amount thereof during the course of the investigation or defense, within ten (10) days after bills supporting the Indemnified Liabilities are received by the Company.

(iv)The indemnity agreement contained herein shall be in addition to (A) any cause of action or similar right of the Indemnitee against the Company or others, and (B) any liabilities the Company may be subject to pursuant to the law.

(h)No Strict Construction. The language used in this Agreement will be deemed to be the language chosen by the parties to express their mutual intent, and no rules of strict construction will be applied against any party.

H.Mechanics of Conversion.

1.To convert any Conversion Amount into shares of Stock on any date (a "Conversion Date"), the Holder shall (A) transmit by electronic mail (or otherwise deliver), for receipt on or prior to 5:00 p.m., New York Time, on such date, a copy of an executed notice of conversion in the form attached hereto as Exhibit I (the "Conversion Notice") to the Company and (B) if required by Section (4)(b)(iii), surrender this Debenture to a nationally recognized overnight delivery service for delivery to the Company (or an indemnification undertaking reasonably satisfactory to the Company with respect to this Debenture in the case of its loss, theft or destruction). On or before the 3^rd Business Day following (i) the date of receipt of a Conversion Notice (the "Share Delivery Date"), the Company shall (X) if legends are not required to be placed on certificates of Stock pursuant to the Securities Purchase Agreement and provided that the Transfer Agent is participating in the Depository Trust Company's ("DTC") Fast Automated Securities Transfer Program, credit such aggregate number of shares of Stock to which the Holder shall be entitled to the Holder's or its designee's balance account with DTC through its DWAC system or (Y) if the Transfer Agent is not participating in the DTC Fast Automated Securities Transfer Program, issue and deliver to the address as specified in the Conversion Notice, a certificate, registered in the name of the Holder or its designee, for the number of shares of Stock to which the Holder shall be entitled which certificates shall not bear any restrictive legends unless required pursuant to the Securities Purchase Agreement. If this Debenture is physically surrendered for conversion and the outstanding Principal of this Debenture is greater than the Principal portion of the Conversion Amount being converted, then the Company shall as soon as practicable and in no event later than 3 Business Days after receipt of this Debenture and at its own expense, issue and deliver to the holder a new Debenture representing the outstanding Principal not converted. The Person or Persons entitled to receive the shares of Stock issuable upon a conversion of this Debenture shall be treated for all purposes as the record holder or holders of such shares of Stock upon the transmission of a Conversion Notice.

2.Company's Failure to Timely Convert. Company shall issue and deliver a certificate to the Holder or credit the Holder's balance account with DTC for the number of shares of Stock to which the Holder is entitled upon each conversion of any Conversion Amount within 3 Trading Days after the Company's receipt by electronic mail of a copy of a Conversion Notice. If the Company fails to deliver such shares within 3 Trading Days, unless such delivery failure results from a failure of the Company’s transfer agent to issue such shares as a result of an act of terrorism, war, natural disaster, act of god or other force majeure event, (a "Conversion Failure"), and if on or after a Conversion Failure the Holder purchases (in an open market transaction or otherwise) Stock to deliver in satisfaction of a sale by the Holder of Stock issuable upon such conversion that the Holder anticipated receiving from the Company (a "Buy-In"), then the Company shall, within 3 Business Days after the Holder's request and in the Holder's discretion, either (i) pay cash to the Holder in an amount equal to the Holder's total purchase price (including brokerage commissions and other out of pocket expenses, if any) for the shares of Stock so purchased (the "Buy-In Price"), at which point the Company's obligation to deliver such certificate (and to issue such Stock) shall terminate, or (ii) promptly honor its obligation to deliver to the Holder a certificate or certificates representing such Stock and pay cash to the Holder in an amount equal to the excess (if any) of the Buy-In Price over the product of (A) such number of shares of Stock, times (B) the Closing Bid Price on the Conversion Date.

3.Book-Entry. Notwithstanding anything to the contrary set forth herein, upon conversion of any portion of this Debenture in accordance with the terms hereof, the Holder shall not be required to physically surrender this Debenture to the Company unless (A) the full Conversion Amount represented by this Debenture is being converted or (B) the Holder has provided the Company with prior written notice (which notice may be included in a Conversion Notice) requesting reissuance of this Debenture upon physical surrender of this Debenture. The Holder and the Company shall maintain records showing the Principal and Interest converted and the dates of such conversions or shall use such other method, reasonably satisfactory to the Holder and the Company, so as not to require physical surrender of this Debenture upon conversion.

I.Limitations on Conversions.

1.Beneficial Ownership. The Holder shall not have the right to convert any portion of this Debenture or otherwise receive shares of Stock hereunder to the extent that after giving effect to such conversion or receipt of such shares, the Holder, together with any affiliate thereof, would beneficially own (as determined in accordance with Section 13(d) of the Exchange Act and the rules promulgated thereunder) in excess of 4.99% of the number of shares of Stock outstanding immediately after giving effect to such conversion or receipt of shares as payment of interest. Since the Holder will not be obligated to report to the Company the number of shares of Stock it may hold at the time of a conversion hereunder, unless the conversion at issue would result in the issuance of shares of Stock in excess of 4.99% of the then outstanding shares of Stock without regard to any other shares which may be beneficially owned by the Holder or an affiliate thereof, the Holder shall have the authority and obligation to determine whether the restriction contained in this Section will limit any particular conversion hereunder and to the extent that the Holder determines that the limitation contained in this Section applies, the determination of which portion of the principal amount of this Debenture is convertible shall be the responsibility and obligation of the Holder. If the Holder has delivered a Conversion Notice for a principal amount of this Debenture that, without regard to any other shares that the Holder or its affiliates may beneficially own, would result in the issuance in excess of the permitted amount hereunder, the Company shall notify the Holder of this fact and shall honor the conversion for the maximum principal amount permitted to be converted on such Conversion Date in accordance with Section 4(a) and, any principal amount tendered for conversion in excess of the permitted amount hereunder shall remain outstanding under this Debenture. The provisions of this Section may be waived by a Holder (but only as to itself and not to any other Holder) upon not less than 65 days prior notice to the Company. Other Holders shall be unaffected by any such waiver.

J.Other Provisions.

1.The Company shall at all times reserve and keep available out of its authorized Stock the full number of shares of Stock issuable upon conversion of all outstanding amounts under this Debenture; and within 3 Business Days following the receipt by the Company of a Holder's notice that such minimum number of Underlying Shares is not so reserved, the Company shall promptly reserve a sufficient number of shares of Stock to comply with such requirement.

6

2.All calculations under this Debenture shall be rounded to the nearest $0.0001 or whole share.

K.Adjustment of the Fixed Conversion Price upon Subdivision or Combination of Stock. If the Company, at any time while this Debenture is outstanding, shall (a) pay a stock dividend or otherwise make a distribution or distributions on shares of its Stock or any other equity or equity equivalent securities payable in shares of its Stock, (b) subdivide outstanding shares of Stock into a larger number of shares, (c) combine (including by way of reverse stock split) outstanding shares of its Stock into a smaller number of shares, or (d) issue by reclassification of shares of the Stock any shares of capital stock of the Company, then the Fixed Conversion Price, as applicable, shall be multiplied by a fraction of which the numerator shall be the number of shares of Stock (excluding treasury shares, if any) outstanding before such event and of which the denominator shall be the number of shares of Stock outstanding after such event. Any adjustment made pursuant to this Section 4(g) shall become effective immediately after the record date for the determination of stockholders entitled to receive such dividend or distribution and shall become effective immediately after the effective date in the case of a subdivision, combination or re-classification.

REISSUANCE OF THIS DEBENTURE.

L.Transfer. If this Debenture is to be transferred, the Holder shall surrender this Debenture to the Company, whereupon the Company will, subject to the satisfaction of the transfer provisions of the Securities Purchase Agreement, forthwith issue and deliver upon the order of the Holder a new Debenture (in accordance with Section 5(d)), registered in the name of the registered transferee or assignee, representing the outstanding Principal being transferred by the Holder and, if less than the entire outstanding Principal is being transferred, a new Debenture (in accordance with Section 5(d)) to the Holder representing the outstanding Principal not being transferred. The Holder and any assignee, by acceptance of this Debenture, acknowledge and agree that, by reason of the provisions of Section 4(c)(iii) following conversion or redemption of any portion of this Debenture, the outstanding Principal represented by this Debenture may be less than the Principal stated on the face of this Debenture.

M.Lost, Stolen or Mutilated Debenture. Upon receipt by the Company of evidence reasonably satisfactory to the Company of the loss, theft, destruction or mutilation of this Debenture, and, in the case of loss, theft or destruction, of any indemnification undertaking by the Holder to the Company in customary form and, in the case of mutilation, upon surrender and cancellation of this Debenture, the Company shall execute and deliver to the Holder a new Debenture (in accordance with Section 5(d)) representing the outstanding Principal.

N.Debenture Exchangeable for Different Denominations. This Debenture is exchangeable, upon the surrender hereof by the Holder at the principal office of the Company, for a new Debenture or Debentures (in accordance with Section 5(d)) representing in the aggregate the outstanding Principal of this Debenture, and each such new Debenture will

7

represent such portion of such outstanding Principal as is designated by the Holder at the time of such surrender.

O.Issuance of New Debentures.

As long as this Debenture is outstanding, the Company shall not and shall cause their subsidiaries not to, without the consent of the Holder, (i) amend its certificate of incorporation, bylaws or other charter documents so as to adversely affect any rights of the Holder (which shall include combining (by way of reverse stock split) outstanding shares of Stock into a smaller number of shares); (ii) repay, repurchase or offer to repay, repurchase or otherwise acquire shares of its Stock or other equity securities other than as to the Underlying Shares to the extent permitted or required under the Transaction Documents or as may be required pursuant to the Company’s convertible loans outstanding as of the date hereof, or as long as there is not in existence any uncured Event of Default, as may be permitted pursuant to the Company’s convertible loans; or (iii) enter into any agreement with respect to any of the foregoing. This Debenture shall not entitle the Holder to any of the rights of a stockholder of the Company, including without limitation, the right to vote, to receive dividends and other distributions, or to receive any notice of, or to attend, meetings of stockholders or any other proceedings of the Company, unless and to the extent converted into shares of Stock in accordance with the terms hereof.

The Company covenants (to the extent that it may lawfully do so) that it shall not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law or other law which would prohibit or forgive the Company from paying all or any portion of the principal of or interest on this Debenture as contemplated herein, wherever enacted, now or at any time hereafter in force, or which may affect the covenants or the performance of this indenture, and the Company (to the extent it may lawfully do so) hereby expressly waives all benefits or advantage of any such law, and covenants that it will not, by resort to any such law, hinder, delay or impeded the execution of any power herein granted to the Holder, but will suffer and permit the execution of every such as though no such law has been enacted.

Whenever any payment or other obligation hereunder shall be due on a day other than a Business Day, such payment shall be made on the next succeeding Business Day.

THE PARTIES HEREBY KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVE THE RIGHT ANY OF THEM MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION BASED HEREON OR ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS AGREEMENT OR ANY TRANSACTION DOCUMENT OR ANY COURSE OF CONDUCT, COURSE OF DEALING, STATEMENTS (WHETHER VERBAL OR WRITTEN) OR ACTIONS OF ANY PARTY.

2. Exercise of Warrant.

(a)Subject to the terms and conditions hereof, this Warrant may be exercised by the holder hereof then registered on the books of the Company, pro rata as hereinafter provided, at any time on any Business Day on or after the opening of business on such Business Day, commencing with the first day after the date hereof, and prior to 5:00 P.M. Eastern Time on the Expiration Date (i) by delivery of a written notice, in the form of the subscription notice attached as Exhibit A hereto (the “Exercise Notice”), of such holder’s election to exercise this Warrant, which notice shall specify the number of Warrant Shares to be purchased, payment to the Company of an amount equal to the Warrant Exercise Price(s) applicable to the Warrant Shares being purchased, multiplied by the number of Warrant Shares (at the applicable Warrant Exercise Price) as to which this Warrant is being exercised (plus any applicable issue or transfer taxes) (the “Aggregate Exercise Price”) in cash or wire transfer of immediately available funds and the surrender of this Warrant (or an indemnification undertaking with respect to this Warrant in the case of its loss, theft or destruction) to a common carrier for overnight delivery to the Company or (ii) if at the time of exercise, the Warrant Shares are not subject to an effective registration statement or if an Event of Default has occurred and is continuing, by delivering an Exercise Notice and in lieu of making payment of the Aggregate Exercise Price in cash or wire transfer, elect instead to receive upon such exercise the “Net Number” of shares of Common Stock determined according to the following formula (the “Cashless Exercise”):

Net Number = (A x B) – (A x C)

B

For purposes of the foregoing formula:

A = the total number of Warrant Shares with respect to which this Warrant is then being exercised.

B = the Closing Bid Price of the Common Stock on the date of exercise of the Warrant.

4

C = the Warrant Exercise Price then in effect for the applicable Warrant Shares at the time of such exercise.

In the event of any exercise of the rights represented by this Warrant in compliance with this Section 2, the Company shall on or before the 3^rd Business Day following the date of receipt of the Exercise Notice, the Aggregate Exercise Price and this Warrant (or an indemnification undertaking with respect to this Warrant in the case of its loss, theft or destruction) and the receipt of the representations of the holder specified in Section 6 hereof, if requested by the Company (the “Exercise Delivery Documents”), and if the Warrant Shares are subject to an effective and current Registration Statement and the Common Stock is DTC eligible, credit such aggregate number of shares of Common Stock to which the holder shall be entitled to the holder’s or its designee’s balance account with The Depository Trust Company; provided, however, if the holder who submitted the Exercise Notice requested physical delivery of any or all of the Warrant Shares, or, if the Warrant Shares are not subject to an effective and current Registration Statement and the Common Stock is not DTC eligible then the Company shall, on or before the 3^rd Business Day following receipt of the Exercise Delivery Documents, issue and surrender to a common carrier for overnight delivery to the address specified in the Exercise Notice, a certificate, registered in the name of the holder, for the number of shares of Common Stock to which the holder shall be entitled pursuant to such request. The Warrant Shares shall be issued with a legend unless they are subject to an effective and current Registration Statement or they are being transferred pursuant to an exemption from such registration requirements, the availability of which is confirmed in an opinion of counsel acceptable to the Company’s Transfer Agent. Upon delivery of the Exercise Notice pursuant to the notice delivery provisions in Section 11 herein and Aggregate Exercise Price referred to in clause (i) or (ii) above the holder of this Warrant shall be deemed for all corporate purposes to have become the holder of record of the Warrant Shares with respect to which this Warrant has been exercised. In the case of a dispute as to the determination of the Warrant Exercise Price, the Closing Bid Price or the arithmetic calculation of the Warrant Shares, the Company shall promptly issue to the holder the number of Warrant Shares that is not disputed and shall submit the disputed determinations or arithmetic calculations to the holder via facsimile within 1 Business Day of receipt of the holder’s Exercise Notice.

(b)If the holder and the Company are unable to agree upon the determination of the Warrant Exercise Price or arithmetic calculation of the Warrant Shares within 1 day of such disputed determination or arithmetic calculation being submitted to the holder, then the Company shall immediately submit via electronic mail (i) the disputed determination of the Warrant Exercise Price or the Closing Bid Price to an independent, reputable investment banking firm or (ii) the disputed arithmetic calculation of the Warrant Shares to its independent, outside accountant. The Company shall cause the investment banking firm or the accountant, as the case may be, to perform the determinations or calculations and notify the Company and the holder of the results no later than 72 hours from the time it receives the disputed determinations or calculations. Such investment banking firm’s or accountant’s determination or calculation, as the case may be, shall be deemed conclusive absent manifest error.

5

(c)Unless the rights represented by this Warrant shall have expired or shall have been fully exercised, the Company shall, as soon as practicable and in no event later than 5 Business Days after any exercise and at its own expense, issue a new Warrant identical in all respects to this Warrant exercised except it shall represent rights to purchase the number of Warrant Shares purchasable immediately prior to such exercise under this Warrant exercised, less the number of Warrant Shares with respect to which such Warrant is exercised.

(d)No fractional Warrant Shares are to be issued upon any pro rata exercise of this Warrant, but rather the number of Warrant Shares issued upon such exercise of this Warrant shall be rounded up or down to the nearest whole number.

(e)If the Company or its Transfer Agent shall fail for any reason or for no reason to issue to the holder within 5 days of receipt of the Exercise Delivery Documents, a certificate for the number of Warrant Shares to which the holder is entitled or to credit the holder’s balance account with The Depository Trust Company for such number of Warrant Shares to which the holder is entitled upon the holder’s exercise of this Warrant, unless such failure results from a failure of the Company’s Transfer Agent to issue such shares as a result of an act of terrorism, war, natural disaster, act of god or other force majure event, the Company shall, in addition to any other remedies under this Warrant or otherwise available to such holder, pay as additional damages in cash to such holder on each day the issuance of such certificate for Warrant Shares is not timely effected an amount equal to 0.025% of the product of (A) the sum of the number of Warrant Shares not issued to the holder on a timely basis and to which the holder is entitled, and (B) the Closing Bid Price of the Common Stock for the trading day immediately preceding the last possible date which the Company could have issued such Common Stock to the holder without violating this Section 2.

(f)If within 5 days after the Company’s receipt of the Exercise Delivery Documents and the written request of the Holder that a new Warrant be issued, the Company fails to deliver a new Warrant to the holder for the number of Warrant Shares to which such holder is entitled pursuant to Section 2 hereof, then, in addition to any other available remedies under this Warrant, or otherwise available to such holder, the holder shall be entitled to exercise or transfer its rights under such new warrant as if it had received such new Warrant and the Company shall be obligated to honor such exercises or transfers as if the holder had submitted the new Warrant without violating this Section 2.

3. Covenants as to Common Stock. The Company hereby covenants and agrees as follows:

(a)This Warrant is, and any Warrants issued in substitution for or replacement of this Warrant will upon issuance be, duly authorized and validly issued.

(b)All Warrant Shares which may be issued upon the exercise of the rights represented by this Warrant will, upon issuance, be validly issued, fully paid and nonassessable and free from all taxes, liens and charges with respect to the issue thereof.

(c)During the period within which the rights represented by this Warrant may be exercised, the Company will at all times have authorized and reserved at least 100% of the

6

number of shares of Common Stock needed to provide for the exercise of the rights then represented by this Warrant and the par value of said shares will at all times be less than or equal to the applicable Warrant Exercise Price. If at any time the Company does not have a sufficient number of shares of Common Stock authorized and available, then the Company shall call and hold a special meeting of its stockholders within 60 days of that time for the sole purpose of increasing the number of authorized shares of Common Stock.

(d)If at any time after the date hereof the Company shall file a Registration Statement, the Company shall include the Warrant Shares issuable to the holder, pursuant to the terms of this Warrant and shall maintain, so long as any other shares of Common Stock shall be so listed, such listing of all Warrant Shares from time to time issuable upon the exercise of this Warrant on the Primary Market or such national securities exchange or automated quotation system on which the Common Stock of the Company is listed; and the Company shall so list on the Primary Market or such national securities exchange or automated quotation system on which the Common Stock of the Company is listed, as the case may be, and shall maintain such listing of, any other shares of capital stock of the Company issuable upon the exercise of this Warrant Shares if and so long as any shares of the same class shall be listed on the Primary Market or such national securities exchange or automated quotation system on which the Common Stock of the Company is listed.

(e)The Company will not, by amendment of its Articles 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 to be observed or performed by it hereunder, but will at all times in good faith assist in the carrying out of all the provisions of this Warrant and in the taking of all such action as may reasonably be requested by the holder of this Warrant in order to protect the exercise privilege of the holder of this Warrant. The Company will not increase the par value of any shares of Common Stock receivable upon the exercise of this Warrant above the Warrant Exercise Price then in effect, and (ii) will take all such actions as may be necessary or appropriate in order that the Company may validly and legally issue fully paid and nonassessable shares of Common Stock upon the exercise of this Warrant.

(f)This Warrant will be binding upon any entity succeeding to the Company by merger, consolidation or acquisition of all or substantially all of the Company’s assets.

4. Taxes. The Company shall pay any and all taxes, except any applicable withholding, which may be payable with respect to the issuance and delivery of Warrant Shares upon exercise of this Warrant.

5. Warrant Holder Not Deemed a Stockholder. Except as otherwise specifically provided herein, no holder, as such, of this Warrant shall be entitled to vote or receive dividends or be deemed the holder of shares of capital stock of the Company for any purpose, nor shall anything contained in this Warrant be construed to confer upon the holder hereof, as such, 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

7

holder of this Warrant of the Warrant Shares which he or she is then entitled to receive upon the due exercise of this Warrant. In addition, nothing contained in this Warrant shall be construed as imposing any liabilities on such holder to purchase any securities (upon exercise of this Warrant or otherwise) or as a stockholder of the Company, whether such liabilities are asserted by the Company or by creditors of the Company. Notwithstanding this Section 5, the Company will provide the holder of this Warrant with copies of the same notices and other information given to the stockholders of the Company generally, contemporaneously with the giving thereof to the stockholders.

6. Representations of Holder. The holder of this Warrant, by the acceptance hereof, represents that it is acquiring this Warrant and the Warrant Shares for its own account for investment only and not with a view towards, or for resale in connection with, the public sale or distribution of this Warrant or the Warrant Shares, except pursuant to sales registered or exempted under the Securities Act; provided, however, that by making the representations herein, the holder does not agree to hold this Warrant or any of the Warrant Shares for any minimum or other specific term and reserves the right to dispose of this Warrant and the Warrant Shares at any time in accordance with or pursuant to a registration statement or an exemption under the Securities Act. The holder of this Warrant further represents, by acceptance hereof, that, as of this date, such holder is an “accredited investor” as such term is defined in Rule 501(a)(1) of Regulation D promulgated by the Securities and Exchange Commission under the Securities Act (an “Accredited Investor”). Upon exercise of this Warrant the holder shall, if requested by the Company, confirm in writing, in a form satisfactory to the Company, that the Warrant Shares so purchased are being acquired solely for the holder’s own account and not as a nominee for any other party, for investment, and not with a view toward distribution or resale and that such holder is an Accredited Investor. If such holder cannot make such representations because they would be factually incorrect, it shall be a condition to such holder’s exercise of this Warrant that the Company receive such other representations as the Company considers reasonably necessary to assure the Company that the issuance of its securities upon exercise of this Warrant shall not violate any United States or state securities laws.

7. Ownership and Transfer.

(a)The Company shall maintain at its principal executive offices (or such other office or agency of the Company as it may designate by notice to the holder hereof), a register for this Warrant, in which the Company shall record the name and address of the person in whose name this Warrant has been issued, as well as the name and address of each transferee. The Company may treat the person in whose name any Warrant is registered on the register as the owner and holder thereof for all purposes, notwithstanding any notice to the contrary, but in all events recognizing any transfers made in accordance with the terms of this Warrant.

8. Adjustment of Warrant Exercise Price. The Warrant Exercise Price of this Warrant shall be adjusted from time to time as follows:

(a)Adjustment of Warrant Exercise Price. If and whenever on or after the Issuance Date of this Warrant, the Company issues or sells, or is deemed to have issued or sold, any shares of Common Stock (other than Excluded Securities) for a consideration per share (the “New Issuance Price”) less than the Warrant Exercise Price in effect immediately

8

prior to such issuance or sale (the “Applicable Price”), then immediately after such issue or sale the Warrant Exercise Price then in effect shall be reduced to an amount equal to such New Issuance Price.

(b)Effect on Warrant Exercise Price of Certain Events. For purposes of determining the adjusted Warrant Exercise Price under Section 8(a) above, the following shall be applicable:

(i)Issuance of Options. If after the date hereof, 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 or exchange of any Convertible Securities issuable upon exercise of any such Option is less than the Applicable 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 8(b)(i), the lowest price per share for which one share of Common Stock is issuable upon exercise of such Options or upon conversion or exchange of such Convertible Securities 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 or upon conversion or exchange of any convertible security issuable upon exercise of such Option. No further adjustment of the Warrant Exercise Price shall be made upon the actual issuance of such Common Stock or of such Convertible Securities upon the exercise of such Options or upon the actual issuance of such Common Stock upon conversion 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 1 share of Common Stock is issuable upon the conversion or exchange thereof is less than the Applicable 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 8(b)(ii), the lowest price per share for which one share of Common Stock is issuable upon such conversion or exchange 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 or exchange of such convertible security. No further adjustment of the Warrant Exercise Price shall be made upon the actual issuance of such Common Stock upon conversion 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 the Warrant Exercise Price had been or are to be made pursuant to other provisions of this Section 8(b), no further adjustment of the Warrant Exercise Price 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 or exchange of any Convertible Securities, or the rate at which any Convertible Securities are convertible into or exchangeable for Common Stock changes at any time, the Warrant Exercise Price in effect at the time of such change shall be adjusted to the Warrant

9

Exercise Price which would have been in effect at such time had such Options or Convertible Securities provided for such changed purchase price, additional consideration or changed conversion rate, as the case may be, at the time initially granted, issued or sold. For purposes of this Section 8(b)(iii), if the terms of any Option or convertible security that was outstanding as of the Issuance Date of this Warrant are changed in the manner described in the immediately preceding sentence, then such Option or convertible security and the Common Stock deemed issuable upon exercise, conversion or exchange thereof shall be deemed to have been issued as of the date of such change. No adjustment pursuant to this Section 8(b) shall be made if such adjustment would result in an increase of the Warrant Exercise Price then in effect.

(iv)Calculation of Consideration Received. If any Common Stock, Options or Convertible Securities are issued or sold or deemed to have been issued or sold for cash, the consideration received therefore will be deemed to be the gross amount received by the Company therefore; provided that any deductions made from the gross amount are commercially reasonable commissions and expenses in connection with such capital raise. If any 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 marketable securities, in which case the amount of consideration received by the Company will be the market price of such securities on the date of receipt of such securities. If any 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 therefore 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 Common Stock, Options or Convertible Securities, as the case may be. The fair value of any consideration other than cash or securities will be determined jointly by the Company and the holders of Warrants representing at least two-thirds (b) of the Warrant Shares issuable upon exercise of the Warrants then outstanding. 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 (10^th) day following the Valuation Event by an independent, reputable appraiser jointly selected by the Company and the holders of Warrants representing at least two-thirds (b) of the Warrant Shares issuable upon exercise of the Warrants then outstanding. The determination of such appraiser shall be final and binding upon all parties and the fees and expenses of such appraiser shall be borne jointly by the Company and the holders of Warrants.

(v)Integrated Transactions. 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 $.01.

(vi)Treasury Shares. The number of shares of Common Stock outstanding at any given time does not include shares owned or held by or for the account of the Company, and the disposition of any shares so owned or held will be considered an issue or sale of Common Stock.

10

(vii)Record Date. If the Company takes a record of the holders of Common Stock for the purpose of entitling them (1) to receive a dividend or other distribution payable in Common Stock, Options or in Convertible Securities or (2) to subscribe for or purchase 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.

(c)Adjustment of Warrant Exercise Price upon Subdivision or Combination of Common Stock. If the Company at any time after the date of issuance of this Warrant subdivides (by any stock split, stock dividend, recapitalization or otherwise) one or more classes of its outstanding shares of Common Stock into a greater number of shares, any Warrant Exercise Price in effect immediately prior to such subdivision will be proportionately reduced and the number of shares of Common Stock obtainable upon exercise of this Warrant will be proportionately increased. If the Company at any time after the date of issuance of this Warrant combines (by combination, reverse stock split or otherwise) one or more classes of its outstanding shares of Common Stock into a smaller number of shares, any Warrant Exercise Price in effect immediately prior to such combination will be proportionately increased and the number of Warrant Shares issuable upon exercise of this Warrant will be proportionately decreased. Any adjustment under this Section 8(c) shall become effective at the close of business on the date the subdivision or combination becomes effective.

(d)Distribution of Assets. 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 dividend, spin off, reclassification, corporate rearrangement or other similar transaction) (a “Distribution”), at any time after the issuance of this Warrant, then, in each such case:

(i)any Warrant 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 Warrant Exercise Price by a fraction of which (A) the numerator shall be the Closing Sale Price of the Common Stock on the trading day immediately preceding such record date minus the value of the Distribution (as determined in good faith by the Company’s Board of Directors) applicable to one share of Common Stock, and (B) the denominator shall be the Closing Sale Price of the Common Stock on the trading day immediately preceding such record date; and

(ii)either (A) the number of Warrant Shares obtainable upon exercise of this Warrant shall be increased to a number of shares equal to the number of shares of Common Stock obtainable 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 multiplied by the reciprocal of the fraction set forth in the immediately preceding clause (i), or (B) in the event that the Distribution is of common stock of a company whose common stock is traded on a national securities exchange or a national automated quotation system, then the holder of this Warrant shall receive an additional warrant to purchase Common Stock, the terms of which shall

11

be identical to those of this Warrant, except that such warrant shall be exercisable into the amount of the assets that would have been payable to the holder of this Warrant pursuant to the Distribution had the holder exercised this Warrant immediately prior to such record date and with an exercise price equal to the amount by which the exercise price of this Warrant was decreased with respect to the Distribution pursuant to the terms of the immediately preceding clause (i).

(e)Certain Events. If any event occurs of the type contemplated by the provisions of this Section 8 but not expressly provided for by such provisions (including, without limitation, the granting of stock appreciation rights, phantom stock rights or other rights with equity features), then the Company’s Board of Directors will make an appropriate adjustment in the Warrant Exercise Price and the number of shares of Common Stock obtainable upon exercise of this Warrant so as to protect the rights of the holders of the Warrants; provided, except as set forth in section 8(c),that no such adjustment pursuant to this Section 8(e) will increase the Warrant Exercise Price or decrease the number of shares of Common Stock obtainable as otherwise determined pursuant to this Section 8.

(f)Voluntary Adjustments By Company. The Company may at any time during the term of this Warrant reduce the then current Exercise Price to any amount and for any period of time deemed appropriate by the Board of Directors of the Company.

(g)Notices.

(i)Immediately upon any adjustment of the Warrant Exercise Price, the Company will give written notice thereof to the holder of this Warrant, setting forth in reasonable detail, and certifying, the calculation of such adjustment.

(ii)The Company will give written notice to the holder of this Warrant at least ten (10) days prior to the date on which the Company closes its books or takes a record (A) with respect to any dividend or distribution upon the Common Stock, (B) with respect to any pro rata subscription offer to holders of Common Stock or (C) for determining rights to vote with respect to any Organic Change (as defined below), dissolution or liquidation, provided that such information shall be made known to the public prior to or in conjunction with such notice being provided to such holder.

(iii)The Company will also give written notice to the holder of this Warrant at least 10 days prior to the date on which any Organic Change, dissolution or liquidation will take place, provided that such information shall be made known to the public prior to or in conjunction with such notice being provided to such holder.

9. Purchase Rights; Reorganization, Reclassification, Consolidation, Merger or Sale.

(a)In addition to any adjustments pursuant to Section 8 above, if at any time the Company grants, issues or sells any Options, Convertible Securities or rights to purchase stock, warrants, securities or other property pro rata to the record holders of any class of Common Stock (the “Purchase Rights”), then the holder of this Warrant will be entitled to acquire, upon the terms applicable to such Purchase Rights, the aggregate Purchase Rights which such holder

12

could have acquired if such holder had held the number of shares of Common Stock acquirable upon complete exercise of this Warrant immediately before the date on which a record is taken for the grant, issuance or sale of such Purchase Rights, or, if no such record is taken, the date as of which the record holders of Common Stock are to be determined for the grant, issue or sale of such Purchase Rights.

(b)Any recapitalization, reorganization, reclassification, consolidation, merger, sale of all or substantially all of the Company’s assets to another Person or other transaction in each case which is effected in such a way that holders of Common Stock are entitled to receive (either directly or upon subsequent liquidation) stock, securities or assets with respect to or in exchange for Common Stock is referred to herein as an “Organic Change.” Prior to the consummation of any (i) sale of all or substantially all of the Company’s assets to an acquiring Person or (ii) other Organic Change following which the Company is not a surviving entity, the Company will secure from the Person purchasing such assets or the successor resulting from such Organic Change (in each case, the “Acquiring Entity”) a written agreement to deliver to each holder of Warrants in exchange for such Warrants, a security of the Acquiring Entity evidenced by a written instrument substantially similar in form and substance to this Warrant (including an adjusted warrant exercise price equal to the value for the Common Stock reflected by the terms of such consolidation, merger or sale, and exercisable for a corresponding number of shares of Common Stock acquirable and receivable upon exercise of the Warrants without regard to any limitations on exercise, if the value so reflected is less than any Applicable Warrant Exercise Price immediately prior to such consolidation, merger or sale). Prior to the consummation of any other Organic Change, the Company shall make appropriate provision to insure that each of the holders of the Warrants will thereafter have the right to acquire and receive in lieu of or in addition to (as the case may be) the Warrant Shares immediately theretofore issuable and receivable upon the exercise of such holder’s Warrants (without regard to any limitations on exercise), such shares of stock, securities or assets that would have been issued or payable in such Organic Change with respect to or in exchange for the number of Warrant Shares which would have been issuable and receivable upon the exercise of such holder’s Warrant as of the date of such Organic Change (without taking into account any limitations or restrictions on the exercisability of this Warrant).

10. Lost, Stolen, Mutilated or Destroyed Warrant. If this Warrant is lost, stolen, mutilated or destroyed, the Company shall promptly, on receipt of an indemnification undertaking (or, in the case of a mutilated Warrant, the Warrant), issue a new Warrant of like denomination and tenor as this Warrant so lost, stolen, mutilated or destroyed.

11. Notice. Any notices, consents, waivers or other communications required or permitted to be given under the terms of this Agreement must be in writing and will be deemed to have been delivered upon: (i) receipt, when delivered personally, (ii) 1 Business Day after deposit with an overnight courier service with next day delivery specified, in each case, properly addressed to the party to receive the same, or (iii) receipt, when sent by electronic mail (provided that the electronic mail transmission is not returned in error or the sender is not otherwise notified of any error in transmission.
