1.7 Beneficial Ownership Limitations.

Accordingly, each Investor (and its affiliates) will not convert any portion of the Notes issued to it in violation of the foregoing. In addition, to the extent any shares of Common Stock issuable or deliverable to an Investor pursuant to any Loan Document would cause the Investor to be deemed a Company Affiliate in violation of the foregoing sentence, the Company shall not issue or cause to be delivered such shares of Common Stock to the Investor and the Investor shall not request the issuance or delivery thereof; provided, however, that the Company shall reserve out of its authorized share capital, sufficient shares of Common Stock to permit it to issue such shares but for the foregoing provisions of this Section 1.7 (“Reserved Shares”).

(b) At such time as an Investor determines that the issuance or delivery of Reserved Shares to it can be made without violating the first sentence of Section 1.7(a) hereof, then the Investor may request that the Company issue and deliver such number of Reserved Shares as the Investor determines it can so receive without being deemed a Company Affiliate and which it so requests (an “Issuance Request”) and the Company shall comply with such Issuance Request as soon as possible thereafter; provided, however, that notwithstanding the foregoing provisions of this Section 1.7, should the Investor in its sole discretion determine that it may be deemed a Company Affiliate prior to the issuance or delivery of the Reserved Shares, the Issuance Request shall specify that the Reserved Shares so requested not be issued or delivered prior to 61 days after such Issuance Request is made (and the provisions of Section 1.7(a) shall continue to apply until the actual issuance or delivery thereof).

(c) To the extent that the limitation contained in this Section 1.7 applies, the determination of whether a Note is convertible (in relation to other securities owned by the Investor) and of which portion of a Note is convertible or that Reserved Shares are issuable or deliverable and how many such Reserved Shares are issuable or deliverable shall be in the sole discretion of such Investor. To ensure compliance with this restriction, the Investor will be deemed to represent to the Company each time it delivers a Notice of Conversion under a Note or an Issuance Request that such Notice of Conversion or Issuance Request has not violated the restrictions set forth in this Section 1.7 and the Company shall have no obligation to verify or confirm the accuracy of such determination. For purposes of this Section 1.7, in determining the number of outstanding shares of Common Stock, an Investor may rely on the number of outstanding shares of Common Stock as reflected in (x) the Company’s most recent Form 10-Q or Form 10-K, as the case may be, (y) a more recent public announcement by the Company or (z) any other notice by the Company or the Company’s Transfer Agent setting forth the number of shares of Common Stock outstanding. Upon the written or oral request of an Investor, the Company shall within two business days confirm orally and in writing to an Investor the number of shares of Common Stock then outstanding. In any case, the number of outstanding shares of Common Stock shall be determined after giving effect to the conversion or exercise of securities of the Company by such Investor or its affiliates since the date as of which such number of outstanding shares of Common Stock was reported.

2.9 Disclosure. No representation or warranty of the Company contained in this Agreement, any certificate or document furnished or to be furnished to the Investors at the Initial or Subsequent Closing or the Financial Statements contains any untrue statement of a material fact or omits to state a material fact necessary in order to make the statement contained herein or therein not misleading in light of the circumstances under which they were made.

2.10 Rights of Others Affecting the Transactions. There are no preemptive rights of any shareholder of the Company, as such, to acquire the Notes or any shares of stock that may be issued to the Investors or its designees in connection with any agreements between the parties hereto. No party other than an Investor has a currently exercisable right of first refusal which would be applicable to any or all of the transactions contemplated by the Loan Documents.

2.11 Non-contravention. The execution and delivery of this Agreement and each of the other Loan Documents by the Company, the issuance of the Securities, and the consummation by the Company of the transactions contemplated by this Agreement and each of the other Loan Documents do not and will not conflict with or result in a breach by the Company of any of the terms or provisions of, or constitute a default under (i) the certificate of incorporation or by-laws of the Company, each as currently in effect, (ii) any indenture, mortgage, deed of trust, or other material agreement or instrument to which the Company is a party or by which it or any of its properties or assets are bound, including any listing agreement for the Common Stock except as herein set forth, or (iii) to its knowledge, any existing applicable law, rule, or regulation or any applicable decree, judgment, or order of any court, United States federal or state regulatory body, administrative agency, or other governmental body having jurisdiction over the Company or any of its properties or assets, except such conflict, breach or default which would not have or result in a Material Adverse Effect.

2.12 Filings. None of the Company’s SEC Documents contained, at the time they were filed, any untrue statement of a material fact or omitted to state any material fact required to be stated therein or necessary to make the statements made therein in light of the circumstances under which they were made, not misleading. Except for its Annual Report for the year ended September 30, 2008, since August 19, 2008, the Company has timely filed all requisite forms, reports and exhibits thereto, if any, required to be filed by the Company with the SEC.

2.13 Absence of Certain Changes. Since the Last Audited Date, there has been no material adverse change and no Material Adverse Effect, except as disclosed in the Company’s SEC Documents. Since the Last Audited Date, except as provided in the Company’s SEC Documents, the Company has not (i) incurred or become subject to any material liabilities (absolute or contingent) except liabilities incurred in the ordinary course of business consistent with past practices; (ii) discharged or satisfied any material lien or encumbrance or paid any material obligation or liability (absolute or contingent), other than current liabilities paid in the ordinary course of business consistent with past practices; (iii) declared or made any payment or distribution of cash or other property to shareholders with respect to its capital stock, or purchased or redeemed, or made any agreements to purchase or redeem, any shares of its capital stock; (iv) sold, assigned or transferred any other tangible assets, or canceled any debts owed to the Company by any third party or claims of the Company against any third party, except in the ordinary course of business consistent with past practices; (v) waived any rights of material value, whether or not in the ordinary course of business, or suffered the loss of any material amount of existing business; (vi) made any increases in employee compensation, except in the ordinary course of business consistent with past practices; or (vii) experienced any material problems with labor or management in connection with the terms and conditions of their employment.

The Company is not aware of any valid basis for any such claim that (either individually or in the aggregate with all other such events and circumstances) could reasonably be expected to have a Material Adverse Effect. There are no outstanding or unsatisfied judgments, orders, decrees, writs, injunctions or stipulations to which the Company is a party or by which it or any of its properties is bound, that involve the transaction contemplated herein or that, alone or in the aggregate, could reasonably be expect to have a Material Adverse Effect.

2.16 No Undisclosed Liabilities or Events. To the best of the Company’s knowledge, the Company has no liabilities or obligations other than those disclosed in the Loan Documents or the Company's SEC Documents or those incurred in the ordinary course of the Company's business since the Last Audited Date, or which individually or in the aggregate, do not or would not have a Material Adverse Effect. No event or circumstances has occurred or exists with respect to the Company or its properties, business, operations, condition (financial or otherwise), or results of operations, which, under applicable law, rule or regulation, requires public disclosure or announcement prior to the date hereof by the Company but which has not been so publicly announced or disclosed. There are no proposals currently under consideration or currently anticipated to be under consideration by the Board of Directors or the executive officers of the Company which proposal would (x) change the articles or certificate of incorporation or other charter document or by-laws of the Company, each as currently in effect, with or without shareholder approval, which change would reduce or otherwise adversely affect the rights and powers of the shareholders of the Common Stock or (y) materially or substantially change the business, assets or capital of the Company, including its interests in subsidiaries.

2.17 No Integrated Offering. Neither the Company nor any of its Affiliates nor any Person acting on its or their behalf has, directly or indirectly, at any time since February 12, 2008, made any offer or sales of any security or solicited any offers to buy any security under circumstances that would eliminate the availability of the exemption from registration under Regulation D in connection with the offer and sale of the Securities as contemplated hereby.

2.18 Fees to Brokers, Finders and Others. Except as specifically contemplated in this Agreement, the Company has taken no action which would give rise to any claim by any Person for brokerage commission, finder's fees or similar payments by the Investors relating to this Agreement or the transactions contemplated hereby. Investors shall have no obligation with respect to any such fees or with respect to any claims made by or on behalf of other Persons for fees of a type contemplated in this paragraph that may be due in connection with the transactions contemplated hereby. The Company shall indemnify and hold harmless each Investor, its employees, officers, directors, agents, and partners, and their respective Affiliates, from and against all claims, losses, damages, costs (including the costs of preparation and attorney's fees) and expenses suffered in respect of any such claimed or existing fees, as and when incurred.

2.19 Full Disclosure. To the best of the Company’s knowledge, there is no fact known to the Company (other than general economic conditions known to the public generally or as disclosed in the Company’s SEC Documents) that has not been disclosed in writing to the Investors that would reasonably be expected to have or result in a Material Adverse Effect.

2.20 Confirmation. The Company confirms that all statements of the Company contained herein shall survive acceptance of this Agreement by the Investors. The Company agrees that, if any events occur or circumstances exist prior to the Subsequent Closing Date which would make any of the Company’s representations, warranties, agreements or other information set forth herein materially untrue or materially inaccurate as of such date, the Company shall immediately notify the Investors in writing prior to such date of such fact, specifying which representation, warranty or covenant is affected and the reasons therefor.

A breach of any of the representations and warranties in this section, shall be deemed a material breach of this Agreement and shall constitute an Event of Default (as defined in the Loan Documents) and the Investors shall be entitled to exercise all remedies available to them under the Loan Documents.

3. Representations and Warranties of the Investors. Each of the Investors hereby severally represents and warrants to the Company as to itself that:

3.1 Authorization. The Investor has full power and authority to enter into this Agreement. This Agreement, when executed and delivered by the Investor, assuming due execution and delivery by the other parties hereto, will constitute a valid and legally binding obligation of the Investor, enforceable in accordance with its terms, except as limited by applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent conveyance, and any other laws of general application affecting enforcement of creditors’ rights generally, and as limited by laws relating to the availability of a specific performance, injunctive relief, or other equitable remedies.

3.2 Accredited Investor. The Investor is (i) an “accredited investor” as that term is defined in Rule 501 of the General Rules and Regulations under the Securities Act, (ii) experienced in making investments of the kind described in this Agreement and the related documents, (iii) able, by reason of the business and financial experience of its officers (if an entity) and professional advisors (who are not affiliated with or compensated in any way by the Company or any of its Affiliates or selling agents), to protect its own interests in connection with the transactions described in this Agreement, and the related documents, and to evaluate the merits and risks of an investment in the Securities, and (iv) able to afford the entire loss of its investment in the Securities.

3.3 Restricted Securities. The Investor understands that the Notes and the Restricted Stock are “restricted securities” under applicable U.S. federal and state securities laws and that, pursuant to these laws, the Investor must hold the Notes indefinitely unless they are registered with the Securities and Exchange Commission and qualified by state authorities, or an exemption from such registration and qualification requirements is available.

4. Miscellaneous.

4.1 Registration Rights. Each time the Company proposes to register any of its securities under the Securities Act whether for its own account or for the account of holders of its securities or both (except with respect to registration statements on Forms ▇-▇, ▇-▇ or any successor or similar form or “Rule 145” transactions), it shall include in the registration initiated by the Company (i) all of the shares of Restricted Stock issued to the Investors under any Loan Documents and (ii) all shares of Common Stock into which the Notes may be convertible or have been converted (collectively, "Registrable Stock"). If any particular registration to be effected pursuant to this Section 4.1 shall be, in whole or in part, an underwritten public offering of Common Stock for the account of the Company, the number of shares of Registrable Stock to be included in such an underwriting on behalf of the Investor may be reduced if, and to the extent that, the managing underwriter shall be of the opinion (a written copy of which shall be delivered to the Investor) that the inclusion of all of the shares of Registrable Stock requested to be included in such underwriting by the Investor would materially and adversely affect the marketing of the Common Stock to be sold by the Company under such registration statement. The Company shall comply with all legal requirements to maintain “evergreen” any registration statement that includes any Registrable Stock for so long as any Notes are outstanding or any Registrable Stock is outstanding that has not yet been sold thereunder.

As to any matters not expressly provided for by the Loan Documents, the Agent shall not be required to exercise any discretion or take any action, but shall be required to act or to refrain from acting (and shall be fully protected in so acting or refraining from acting) upon the instructions of the Investors, and any action so taken or not so taken by the Agent shall be binding upon all the Investors; provided, however, that the Agent shall not be required to take any action which exposes the Agent to liability in such capacity, which could result in the Agent incurring any costs and expenses or which is contrary to this Agreement or applicable law.

(b) Indemnification. Each Investor hereby agrees to indemnify and hold harmless the Agent from and against any and all liabilities, obligations, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever which may be imposed on, incurred by, or asserted against the Agent (in its capacity as agent for the Investors) in any way relating to or arising out of the Loan Documents or any action taken or admitted by the Agent under or in respect of the Loan Documents; provided that no Investor shall be liable for any portion of such liabilities, obligations, damages, penalties, actions, judgments, suits, costs, expenses or disbursements resulting from the Agent’s gross negligence or willful misconduct. Without limiting the generality of the foregoing, each Investor agrees to reimburse the Agent promptly upon demand on a pro rata basis in accordance with the then outstanding indebtedness, liabilities and obligations owing to such Investor by the Company in respect of any out-of-pocket expenses (including counsel fees) incurred by the Agent in connection with the preservation of any rights of the Agent or the Investors under, the enforcement of, or legal advice in respect of the rights or responsibilities under, the Loan Documents, to the extent that the Agent is not reimbursed for such expenses by the Company.

(c) Successor Agent. The Agent may, as hereinafter provided, resign at any time by giving not less than 30 days’ written notice thereof to the Investors and the Company.

(iii) each of the Investors hereby further covenants and agrees that upon any such written consent being given by the Investors, they shall co-operate fully with the Agent to the extent requested by the Agent in the collective realization, including, without limitation, the appointment of a receiver and manager to act for their collective benefit; and each Investor covenants and agrees to do all acts and things to make, execute and deliver all agreements and other instruments, including, without limitation, any instruments necessary to effect any registrations, so as to fully carry out the intent and purpose of this Section; and each of the Investors hereby covenants and agrees that it has not heretofore and shall not seek, take, accept or receive any security for any of the obligations and liabilities of the Company under the Loan Documents or under any other document, instrument, writing or agreement ancillary thereto other than such security as is provided hereunder and shall not enter into any agreement with the Company relating in any manner whatsoever to the transactions contemplated hereunder, unless all of the Investors shall at the same time obtain the benefit of any such security or agreement, as the case may be.

Original Issue Discount Term Secured Convertible Promissory Note

$262,500.00

February 12, 2009

FOR VALUE RECEIVED, the undersigned Neah Power Systems, Inc., a Nevada corporation (referred to herein as "Borrower" or the "Company"), promises to pay to the order of Agile Opportunity Fund, LLC, its successors or assigns (the "Lender"), the principal sum of Two Hundred Sixty Two Thousand Five Hundred and 00/100 Dollars ($262,500.00) (the "Face Amount") on August 12, 2009 (the "Maturity Date"), together with interest on the Face Amount of this Note at a rate equal to eighteen percent (18%) per annum calculated on the basis of a 360 day year (the "Interest Rate"). Interest to accrue hereunder through the Maturity Date (assuming no Event of Default hereunder) shall be payable in advance on the date hereof, the amount thereof being $23,625 (the “Prepaid Interest”). Notwithstanding any other provision hereof, interest paid or becoming due hereunder and any other payments hereunder which may constitute interest shall in no event exceed the maximum rate permitted by applicable law.

Interest due hereunder is payable in lawful money of the United States of America to the Lender at the address set forth in that certain Securities Purchase Agreement between the Borrower, the Lender and the other investor thereunder, dated of even date herewith (the "Securities Purchase Agreement"), and pursuant to which this Note is issued. The terms and conditions of the Securities Purchase Agreement and all other Loan Documents, including any other Note, are incorporated by reference herein and made a part hereof. All capitalized terms not otherwise defined herein shall have the respective meanings as set forth in the Securities Purchase Agreement.

Section 1. Conversion.

(a) At any time from the original issue date hereof through the date that this Note is paid in full, Lender shall have the right, in its sole discretion, to convert the then outstanding Face Amount of this Note less the then as yet unamortized portion of the OID Amount (the “Convertible Principal Balance”) plus accrued but unpaid interest under this Note, in whole or in part, into shares (each, a “Conversion Share”) of Common Stock at a conversion price equal to $0.10 per Conversion Share, subject to adjustment as provided in Section 2 herein (the “Conversion Price”).

(b) Lender may convert this Note at the Conversion Price by the surrender of this Note (properly endorsed) to the Company at the principal office of the Borrower, together with the form of Notice of Conversion attached hereto as Annex A (a “Notice of Conversion”) duly completed, dated and executed, specifying therein the principal amount of this Note and/or outstanding interest to be converted. The “Conversion Date” shall be the date that such Notice of Conversion and this Note is duly provided to Borrower hereunder (or, at Lender's option, the next interest payment date with respect to Lender's conversion of any scheduled interest payment). In the event that the Lender shall specify a name or names other than that of the Lender to receive any of the Conversion Shares issuable upon such exercise of the conversion option, the Notice of Conversion also shall be accompanied by payment of all transfer taxes payable upon the issuance of the Conversion Shares to such specified person(s).

(c) On the date of receipt by the Company of the duly completed, dated and executed Notice of Conversion, this Note and applicable transfer taxes, if any, all in accordance with Section 1(b) with respect to a conversion of any portion of this Note, the Lender (and any person(s) receiving Conversion Shares in lieu of the Lender) shall be deemed to have become the holder of record for all purposes of the Conversion Shares to which such valid conversion relates.

(d) As soon as practicable, but not in excess of five business days, after the valid conversion of any portion of this Note, the Company, at the Company’s expense (including the payment by Company of any applicable issuance and similar taxes, but excluding the transfer taxes referred to in Section 1(b)), will cause to be issued in the name of and delivered to the Lender (and/or such other person(s) identified in the Notice of Conversion with respect to such conversion), certificates evidencing the number of duly authorized, validly issued, fully paid and non-assessable Conversion Shares to which the Lender (and/or such other person(s) identified in such Notice of Conversion, shall be entitled to receive upon the conversion), such certificates to be in such reasonable denominations as Lender may request when delivering the Notice of Conversion.

(e) If less than the entire Convertible Principal Balance of this Note is being converted, the Company shall execute and deliver to the Lender a new replacement Note (dated as of the date hereof) evidencing a face amount which is the percentage of the original Face Amount equal to the portion of the Convertible Principal Balance that has not been so converted.

Section 2. Conversion Price Adjustment.

The initial Conversion Price as stated above shall be subject to adjustment from time to time and such Conversion Price as adjusted shall likewise be subject to further adjustment, all as hereinafter set forth.

(a) If and whenever the Company issues or sells any additional securities for consideration equivalent to a per share price of Common Stock (the “Base Price”) less than the Conversion Price in effect immediately prior to such issuance or sale, then immediately upon such issuance or sale the Conversion Price shall be reduced to a new Conversion Price equal to the Base Price; provided, however, that this Section 2(a) shall not be applicable to the issuance of securities to pursuant to the Securities Purchase Agreement.

(b) If the Borrower, at any time while this Note is outstanding, (i) shall pay a stock dividend or otherwise make a distribution or distributions on shares of its Common Stock or any other equity or equity equivalent securities payable in shares of Common Stock, (ii) subdivide outstanding shares of Common Stock into a larger number of shares, (iii) combine (including by way of reverse stock split) outstanding shares of Common Stock into a smaller number of shares, or (iv) issue by reclassification of shares of the Common Stock any shares of capital stock of the Borrower, then the Conversion Price shall be multiplied by a fraction of which the numerator shall be the number of shares of Common Stock (excluding treasury shares, if any) outstanding before such event and of which the denominator shall be the number of shares of Common Stock (excluding treasury shares, if any) outstanding after such event. Any adjustment made pursuant to this paragraph 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 reclassification.

(c) Whenever the Conversion Price shall be adjusted as provided in this Section 2, the Company shall reasonably promptly provide notice of such adjustment to the Lender together with a written statement from an authorized officer of the Company, showing in reasonable detail the facts requiring such adjustment and the Conversion Price that shall be in effect after such adjustment. Notwithstanding the foregoing, no adjustment in the Conversion Price shall be required unless such adjustment would require a change of at least 1% in such Conversion Price; provided, however, that any adjustments which by reason of this Section are not required to be made shall be carried forward and taken into account in any subsequent adjustment.

(d) In case of any consolidation or merger of the Borrower with or into another entity or the conveyance of all or substantially all of the assets of the Borrower to another entity (collectively, an “Organic Change”), this Note shall thereafter be convertible (to the extent such conversion is permitted hereunder) into the number of shares of Common Stock or other securities or property to which a holder of the number of shares of Common Stock of the Borrower deliverable upon conversion of this Note would have been entitled had this Note been converted immediately prior to such Organic Change and held until after the closing of such Organic Change; and, in any such case, appropriate adjustment shall be made in the application of the provisions herein set forth with respect to the rights and interest thereafter of Lender or any subsequent holder of this Note, to the end that the provisions set forth herein shall be thereafter applicable, as nearly as reasonably may be, in relation to any shares of Common Stock or other property thereafter deliverable upon the conversion of this Note.

Section 3. Reservation of Stock. The Borrower covenants that it will at all times reserve and keep available out of its authorized and unissued shares of Common Stock solely for the purpose of issuance upon conversion of this Note as herein provided, free from preemptive rights or any other actual contingent purchase rights of persons other than the Lender, not less than such number of shares of the Common Stock as shall be issuable upon the conversion of the outstanding Face Amount of this Note and accrued and unpaid interest hereunder. If at any time, the Company does not have available an amount of authorized but unissued Common Stock or Common Stock held in treasury necessary to satisfy any conversion of all amounts outstanding under this Note, the Company shall call and hold a special meeting of its stockholders within 30 days of the occurrence of any shortfall in authorized shares for the purpose of approving an increase in the number of shares of authorized Common Stock to an amount sufficient to enable conversion all amounts outstanding under this Note, subject in all respects to compliance with the requirements of Section 14 of the Securities Exchange Act of 1934 to which the Borrower is subject. The Board of Directors of the Company shall recommend that stockholders vote in favor of increasing the number of authorized shares of Common Stock at any such meeting. Each Member of the Board of Directors of the Company shall also vote all of such Director’s voting securities of the Company in favor of such increase in authorized shares. The Borrower covenants that all shares of Common Stock that may be issuable upon conversion of this Note shall, upon issue, be duly and validly authorized, issued and fully paid and nonassessable. No consent of any other party and no consent, license, approval or authorization of, or registration or declaration with, any governmental authority, bureau or agency is required in connection with the execution, delivery or performance by the Borrower, or the validity or enforceability of this Note other than such as have been met or obtained. The execution, delivery and performance of this Note and all other agreements and instruments executed and delivered or to be executed and delivered pursuant hereto or thereto or the securities issuable upon conversion of this will not violate any provision of any existing law or regulation or any order or decree of any court, regulatory body or administrative agency or the certificate of incorporation or by-laws of the Borrower or any mortgage, indenture, contract or other agreement to which the Borrower is a party or by which the Borrower or any property or assets of the Borrower may be bound.

Section 4. No Fractional Shares. Upon a conversion hereunder, the Borrower shall not be required to issue stock certificates representing fractions of shares of Common Stock, and in lieu of any fractional shares which would otherwise be issuable, the Borrower shall issue the next highest whole number of shares of Common Stock, as the case may be.

Section 5. Redemption.

(a) Mandatory Redemption. If at any time while this Note shall be outstanding, the Company shall consummate: (i) a “going-private” transaction whereby the Common Stock shall thereafter cease to be registered under the Exchange Act; or (ii) a Sale of the Company, then the Company shall deliver a written notice to the Lender of the pending consummation of any transaction described in clauses (i) or (ii) of this Section 5 (each, a "Liquidity Event") fifteen (15) days prior thereto and shall redeem this Note in full immediately following the closing of a Liquidity Event (the “Repayment Date”) by paying the applicable Redemption Price. As used herein, "Redemption Price" shall equal all accrued but unpaid interest outstanding under this Note, plus one hundred percent (100%) of the then outstanding Face Amount of this Note. The Borrower shall deliver to the Lender the Redemption Price on the Repayment Date in immediately available funds. For the purpose of clarification, (i) no portion of the Prepaid Interest shall be refundable or otherwise returned to the Company in the event of any such redemption and (ii) after delivery of a notice of a Liquidity Event as provided for in this Section, the Lender shall continue to be entitled to effectuate conversions as contemplated under this Note until such time as the redemption under this Section is consummated.

(b) Voluntary Prepayment. At any time while this Note shall be outstanding, the Company may deliver a written notice of prepayment to the Lender of its intention to prepay the face amount of this Note in full, or in part, fifteen (15) days prior thereto and shall then so prepay such portion of the Note as indicated in the notice together with all accrued but unpaid interest outstanding thereon; provided, however, that no portion of the Prepaid Interest shall be refundable or otherwise returned to the Company in the event of any such prepayment. For the purpose of clarification, after delivery of a notice of prepayment as provided for in this Section, the Lender shall continue to be entitled to effectuate conversions as contemplated under this Note until such time as the prepayment under this Section is consummated.

Section 6. Transferability. This Note and any of the rights granted hereunder are freely transferable by the Lender, in its sole discretion, subject to federal and state securities law restrictions, if any.

Section 7. Event of Default.

(a) An "Event of Default", wherever used herein, means any one of the following events (whatever the reason and whether it shall be voluntary or involuntary or effected by operation of law or pursuant to any judgment, decree or order of any court, or any order, rule or regulation of any administrative or governmental body):

(i) Any default in the payment of the principal of, interest on or other charges in respect of this Note or any other Note as and when the same shall become due and payable (whether the Maturity Date or by acceleration or otherwise);

(ii) The Borrower or any subsidiary shall fail to observe or perform any other material covenant, agreement or warranty contained in, or otherwise commit any breach or default of any provision of this Note or any Loan Document to which it is a party;

(iii) The Borrower or any subsidiary shall commence, or there shall be commenced against the Borrower or any subsidiary, a proceeding under any applicable bankruptcy or insolvency laws as now or hereafter in effect or any successor thereto, or the Borrower or any subsidiary commences any other proceeding under any reorganization, arrangement, adjustment of debt, relief of debtors, dissolution, insolvency or liquidation or similar law of any jurisdiction whether now or hereafter in effect relating to the Borrower or subsidiary or there is commenced against the Borrower or subsidiary any such bankruptcy, insolvency or other proceeding which remains undismissed for a period of 60 days; or the Borrower or subsidiary is adjudicated insolvent or bankrupt; or any order of relief or other order approving any such case or proceeding is entered; or the Borrower or subsidiary suffers any appointment of any custodian, private or court appointed receiver or the like for it or any substantial part of its property which continues undischarged or unstayed for a period of 60 days; or the Borrower or subsidiary makes a general assignment for the benefit of creditors; or the Borrower or subsidiary shall fail to pay, or shall state that it is unable to pay, or shall be unable to pay, its debts generally as they become due; or the Borrower or subsidiary shall by any act or failure to act expressly indicate its consent to, approval of or acquiescence in any of the foregoing; or any corporate or other action is taken by the Borrower or subsidiary for the purpose of effecting any of the foregoing; or

(iv) The Borrower or any subsidiary shall default in any of its obligations under any other note or any mortgage, credit agreement or other facility, indenture agreement, factoring agreement or other instrument under which there may be issued, or by which there may be secured or evidenced any indebtedness for borrowed money or money due under any leasing or factoring arrangement of the Borrower, whether such indebtedness now exists or shall hereafter be created and such default shall result in such indebtedness becoming or being declared due and payable prior to the date on which it would otherwise become due and payable.

(b) Following an Event of Default, the Interest Rate shall increase to 36% per annum immediately following such Event of Default; provided, that the Interest Rate shall thereafter revert back to the prior Interest Rate upon all Events of Default being cured. Upon the occurrence of an Event of Default hereunder, the entire Face Amount of this Note together with any accrued but unpaid interest shall automatically become due and payable. The failure of the Lender to exercise any of its rights hereunder in any particular instance shall not constitute a waiver of the same or of any other right in that or any subsequent instance with respect to the Lender or any subsequent holder. The Lender need not provide and the Borrower hereby waives any presentment, demand, protest or other notice of any kind, and the Lender may immediately and without expiration of any grace period enforce any and all of its rights and remedies hereunder and all other remedies available to it under applicable law.

Section 8. Registration Rights. The Lender is entitled to certain registration rights with respect to the Common Stock issuable upon conversion of this Note as set forth in the Securities Purchase Agreement.

Section 9. Notices. Any and all notices, requests, documents or other communications or deliveries required or permitted to be given or delivered hereunder shall be delivered in accordance with the notice provisions of the Securities Purchase Agreement.

Section 10. Usury. To the extent it may lawfully do so, the Company hereby agrees not to insist upon or plead or in any manner whatsoever claim, and will resist any and all efforts to be compelled to take the benefit or advantage of, usury laws wherever enacted, now or at any time hereafter in force, in connection with any claim, action or proceeding that may be brought by the Lender in order to enforce any right or remedy under any Loan Document. Notwithstanding any provision to the contrary contained in any Loan Document, it is expressly agreed and provided that the total liability of the Company under the Loan Documents for payments in the nature of interest shall not exceed the maximum lawful rate authorized under applicable law (the “Maximum Rate”), and, without limiting the foregoing, in no event shall any rate of interest or default interest, or both of them, when aggregated with any other sums in the nature of interest that the Company may be obligated to pay under the Loan Documents exceed such Maximum Rate. It is agreed that if the maximum contract rate of interest allowed by law and applicable to the Loan Documents is increased or decreased by statute or any official governmental action subsequent to the date hereof, the new maximum contract rate of interest allowed by law will be the Maximum Rate applicable to the Loan Documents from the effective date forward, unless such application is precluded by applicable law. If under any circumstances whatsoever, interest in excess of the Maximum Rate is paid by the Company to Lender with respect to indebtedness evidenced by the Loan Documents, such excess shall be applied by Lender to the unpaid principal balance of any such indebtedness or be refunded to the Company, the manner of handling such excess to be at Lender’s election.

Section 11. Governing Law; Waiver of Jury Trial. This Note and the provisions hereof are to be construed according to and are governed by the laws of the State of New York, without regard to principles of conflicts of laws thereof. Borrower agrees that the New York State Supreme Court located in the County of New York, State of New York shall have exclusive jurisdiction in connection with any dispute concerning or arising out of this Note, the Loan Documents, or otherwise relating to the parties relationship. In any action, lawsuit or proceeding brought to enforce or interpret the provisions of this Note, the Loan Documents and/or arising out of or relating to any dispute between the parties, the Lender shall be entitled to recover all of its costs and expenses relating collection and enforcement of this Note (including without limitation, reasonable attorney’s fees and disbursements) in addition to any other relief to which the Lender may be entitled.

THE BORROWER HEREBY WAIVES TRIAL BY JURY IN ANY ACTION, PROCEEDING, CLAIM OR COUNTERCLAIM, WHETHER IN CONTRACT OR TORT, AT LAW OR IN EQUITY, ARISING OUT OF OR IN ANY WAY RELATING TO THIS NOTE.

Section 12. Successors and Assigns. Subject to applicable securities laws, this Note and the rights and obligations evidenced hereby shall inure to the benefit of and be binding upon the successors of the Company and the successors and assigns of Lender and be freely transferable and assignable by Lender without the consent of the Company.

Section 13. Reimbursement of Expenses. The Company shall reimburse the Lender for any reasonable legal fees and disbursements incurred by the Lender in enforcement of or protection of any of its rights under this Note.

Section 14. Amendment. This Note may be modified or amended or the provisions hereof waived only with the written consent of the Lender and the Company.

Section 15. Severability. Wherever possible, each provision of this Note shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Note shall be prohibited by or invalid under applicable law, such provision shall be ineffective to the extent of such prohibition or invalidity, without invalidating the remainder of such provisions or the remaining provisions of this Note.

Capitalized terms used herein and not otherwise defined herein shall have the meanings specified in the Securities Purchase Agreement.

To induce the Secured Parties to purchase the Notes and pursuant to (i) a Security Agreement dated of even date herewith (as amended or supplemented from time to time in accordance with the terms thereof, the “Security Agreement”) between the Debtor and the Secured Parties (the Secured Parties in the capacity of secured parties under the Security Agreement, together with their successors in such capacity, are referred to as the “Grantees”) and (ii) certain other collateral documents (including this Patent Security Agreement), the Debtor has granted for the benefit of such Grantees a continuing security interest in personal property of the Debtor, including all right, title and interest of the Debtor in, to and under the Patent Collateral (as defined below), to secure the Debtor’s secured obligations under the Security Agreement.

N O W, T H E R E F O R E,

each patent owned and patent application (including all reissues, divisions, continuations, continuation-in-part, extensions and reexaminations thereof) registered or applied for in the United States and all other nations throughout the world by the Debtor, including, without limitation, each patent and patent application referred to in Schedule I hereto (each, a “Patent”);
