(ii) At each Closing, the Company shall deliver to each Purchaser the Note and a Warrant to be purchased by such Purchaser against: (1) payment of the principal amount of such Note, in the amount set forth next to such Purchaser’s name on Exhibit A, by (a) a check payable to the order of the Company drawn on a U.S. bank, (b) wire transfer of immediately available funds to an account designated by the Company or (c) the surrender of promissory notes or other instruments representing indebtedness of the Company to the Purchaser, the principal amounts of which shall be exchanged dollar-for-dollar for principal amount outstanding under such Purchaser's Note (“Exchanged Principal”); (2) delivery of counterpart signature pages to this Agreement, the Note and the Warrant; (3) delivery of a validly completed and executed IRS Form W-8 BEN or IRS Form W-9, as applicable, establishing such Purchaser’s exemption from withholding tax, which forms are attached to this Agreement as Exhibit D; and (4) delivery of a validly completed and executed Certificate of Accredited Investor Status, establishing such Purchaser’s status as an accredited investor as defined in Rule 501(a) of Regulation D promulgated under the Securities Act of 1933, as amended (the “Securities Act”), in the form is attached to this Agreement as Exhibit E (an “Investor Certification”).

(iii) Until the earlier of (a) such time as the aggregate amount of principal indebtedness subject to the terms of this Agreement equals a total of $2,200,000, or such higher amount as approved by the Company’s Board of Directors, or (b) thirty (30) days following the First Closing, the Company may sell additional Notes and Warrants to such persons or entities as determined by the Company, or to any Purchaser who desires to acquire additional Notes and Warrants.

Additional Provisions.

(a) Stock Purchase Agreement. Each Purchaser understands and agrees that the conversion of the Notes into, and exercise of the Warrants for, equity securities of the Company may require such Purchaser’s execution of certain agreements relating to the purchase and sale of such securities as well as registration, co-sale and voting rights, if any, relating to such equity securities.

(b) Security Interest. The indebtedness represented by the Notes shall be secured by all of the assets of the Company in accordance with the provisions of a security agreement among the Company and the Purchasers in the form attached to this Agreement as Exhibit F (the “Security Agreement”).

(b) Authorization. This Agreement, the Notes and the Warrants have been duly authorized by the Board of Directors of the Company; however, (A) the Company has not obtained the necessary corporate approval for the authorization of any new series of Preferred Stock into which the Notes may be convertible or Warrants may be exercisable in accordance with their terms; and (B) a sufficient number of shares of any new series of Preferred Stock has not been authorized under the Company’s Certificate of Incorporation to provide for the issuance of such shares upon conversion or exercise (as applicable) of the Notes and Warrants. The Agreement, the Notes, and the Warrants, when executed and delivered by the Company, shall constitute valid and legally binding obligations of the Company, enforceable against the Company in accordance with their respective terms except as limited by applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent conveyance, and other laws of general application affecting enforcement of creditors’ rights generally, and as limited by laws relating to the availability of specific performance, injunctive relief, or other equitable remedies.

(i) In lieu of exercising this Warrant in the manner provided above in Section 2(a), the Holder may elect to receive shares equal to the value of this Warrant (or the portion thereof being canceled) by surrender of this Warrant at the principal office of the Company together with notice of such election on the purchase/exercise form appended hereto as Exhibit A duly executed by such Holder or such Holder’s duly authorized attorney, in which event the Company shall issue to such Holder a number of shares of Warrant Stock computed using the following formula:

X =

Y (A - B)

Where:

X =

The number of shares of Warrant Stock to be issued to the Holder.

Y =

The number of shares of Warrant Stock purchasable under this Warrant (at the date of such calculation).

A =

The fair market value of one share of Warrant Stock (at the date of such calculation).

B =

The Purchase Price (as adjusted to the date of such calculation).

(ii) For purposes of this Section 2(c), the fair market value of Warrant Stock on the date of calculation shall mean with respect to each share of Warrant Stock:

(A) if the exercise is in connection with an initial public offering of the Company’s Common Stock, and if the Company’s Registration Statement relating to such public offering has been declared effective by the Securities and Exchange Commission, then the

-4-

fair market value shall be the product of (x) the initial “Price to Public” per share specified in the final prospectus with respect to the offering and (y) the number of shares of Common Stock into which each share of Warrant Stock is convertible at the date of calculation;

(B) if (A) is not applicable, the fair market value of Warrant Stock shall be at the highest price per share which the Company could obtain on the date of calculation from a willing buyer (not a current employee or director) for shares of Warrant Stock sold by the Company, from authorized but unissued shares, as determined in good faith by the Board of Directors, unless the Company is at such time subject to an acquisition as described in Section 6 below, in which case the fair market value of Warrant Stock shall be deemed to be the value received by the holders of such stock pursuant to such acquisition.

(d) Delivery to Holder. As soon as practicable after the exercise of this Warrant in whole or in part, and in any event within ten (10) days thereafter, the Company at its expense will cause to be issued in the name of, and delivered to, the Holder, or as such Holder (upon payment by such Holder of any applicable transfer taxes) may direct:

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

(ii) in case such exercise is in part only, a new warrant or warrants (dated the date hereof) of like tenor, calling in the aggregate on the face or faces thereof for the number of shares of Warrant Stock equal (without giving effect to any adjustment therein) to the number of such shares called for on the face of this Warrant minus the number of such shares purchased by the Holder upon such exercise as provided in Section 2(a) or 2(c) above.

Adjustments.

(a) Stock Splits and Dividends. If outstanding shares of the Company’s Common Stock shall be subdivided into a greater number of shares or a dividend in Common Stock shall be paid in respect of Common Stock, the Purchase Price in effect immediately prior to such subdivision or at the record date of such dividend shall simultaneously with the effectiveness of such subdivision or immediately after the record date of such dividend be proportionately reduced. If outstanding shares of Common Stock shall be combined into a smaller number of shares, the Purchase Price in effect immediately prior to such combination shall, simultaneously with the effectiveness of such combination, be proportionately increased. When any adjustment is required to be made in the Purchase Price, the number of shares of Warrant Stock purchasable upon the exercise of this Warrant shall be changed to the number determined by dividing (i) an amount equal to the number of shares issuable upon the exercise of this Warrant immediately prior to such adjustment, multiplied by the Purchase Price in effect immediately prior to such adjustment; by (ii) the Purchase Price in effect immediately after such adjustment.

(b) Reclassification, Etc. In case there occurs any reclassification or change of the outstanding securities of the Company or of any reorganization of the Company (or any other corporation the stock or securities of which are at the time receivable upon the exercise of this Warrant) or any similar corporate reorganization on or after the date hereof, then and in each such

-5-

case the Holder, upon the exercise hereof at any time after the consummation of such reclassification, change, or reorganization shall be entitled to receive, in lieu of the stock or other securities and property receivable upon the exercise hereof prior to such consummation, the stock or other securities or property to which such Holder would have been entitled upon such consummation if such Holder had exercised this Warrant immediately prior thereto, all subject to further adjustment pursuant to the provisions of this Section 3; provided, however, that the operation of this Section 3(b) shall not effect the termination of this Warrant upon a Change of Control (as defined in Section 6 below) pursuant to Section 6 below.

(c) Adjustment Certificate. When any adjustment is required to be made in the Warrant Stock or the Purchase Price pursuant to this Section 3, the Company shall promptly mail to the Holder a certificate setting forth (i) a brief statement of the facts requiring such adjustment; (ii) the Purchase Price after such adjustment; and (iii) the kind and amount of stock or other securities or property into which this Warrant shall be exercisable after such adjustment.

Transfers.

(a) Unregistered Security. Each holder of this Warrant acknowledges that this Warrant and the Warrant Stock of the Company have not been registered under the Securities Act of 1933, as amended (the “Securities Act”), and agrees not to sell, pledge, distribute, offer for sale, transfer or otherwise dispose of this Warrant or any Warrant Stock issued upon its exercise in the absence of (i) an effective registration statement under the Act as to this Warrant or such Warrant Stock and registration or qualification of this Warrant or such Warrant Stock under any applicable U.S. federal or state securities law then in effect; or (ii) an opinion of counsel, satisfactory to the Company, that such registration and qualification are not required. Each certificate or other instrument for Warrant Stock issued upon the exercise of this Warrant shall bear a legend substantially to the foregoing effect.

(b) Transferability. The Holder may not assign, pledge, or otherwise transfer this Warrant without the prior written consent of the Company. Subject to the preceding sentence, this Warrant may be transferred only upon surrender of the original Warrant for registration of transfer, duly endorsed, or accompanied by a duly executed written instrument of transfer in form satisfactory to the Company. Thereupon, a new warrant in substantially the form hereof will be issued to, and registered in the name of, the transferee.

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

5. No Impairment. The Company will not, by amendment of its charter or through reorganization, consolidation, merger, dissolution, sale of assets or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of this Warrant, but will (subject

-6-

to Section 14 below) at all times in good faith assist in the carrying out of all such terms and in the taking of all such action as may be necessary or appropriate in order to protect the rights of the holder of this Warrant against impairment.

6. Termination. This Warrant (and the right to purchase securities upon exercise hereof) shall automatically terminate upon the earliest to occur of the following (the “Expiration Date”): (a) _________ __, 2013; (b) immediately prior to a Change of Control; (c) the closing of a firm commitment underwritten public offering pursuant to a registration statement under the Securities Act; or (d) the date that is thirty (30) days following the Maturity Date of the Note(s) issued to the Holder contemporaneously with the issuance of this Warrant in the event the Next Financing does not occur prior to the Maturity Date of such Note(s) and a Negotiated Conversion does not occur within thirty (30) days following the Maturity Date of such Note(s).

The term “Change of Control” shall mean the sale, conveyance or other disposition of all or substantially all of the Company’s property or business or the Company’s merger with or into or consolidation with any other corporation, limited liability company or other entity (other than a wholly owned subsidiary of the Company), provided that the term “Change of Control” shall not include a merger of the Company effected exclusively for the purpose of changing the domicile of the Company, to an equity financing in which the Company is the surviving corporation, or to a transaction in which the stockholders of the Company immediately prior to the transaction own 50% or more of the voting power of the surviving corporation following the transaction.

Notices of Certain Transactions. In case:

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

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

(d)

of any redemption of the Common Stock or Preferred Stock,

then, and in each such case, the Company will mail or cause to be mailed to the Holder of this Warrant a notice specifying, as the case may be, (i) the date on which a record is to be taken for the purpose of such dividend, distribution or right, and stating the amount and character of such dividend, distribution or right; or (ii) the effective date on which such reorganization,

-7-

reclassification, consolidation, merger, transfer, dissolution, liquidation, winding-up, redemption or conversion is to take place, and the time, if any is to be fixed, as of which the holders of record of Preferred Stock (or such other stock or securities at the time deliverable upon such reorganization, reclassification, consolidation, merger, transfer, dissolution, liquidation, winding-up, redemption or conversion) are to be determined. Such notice shall be mailed at least ten (10) days prior to the record date or effective date for the event specified in such notice.

8. Reservation of Stock. The Company will at all times reserve and keep available, solely for the issuance and delivery upon the exercise of this Warrant, such shares of Warrant Stock and other stock, securities and property, as from time to time shall be issuable upon the exercise of this Warrant.

9. Exchange of Warrants. Upon the surrender by the Holder of any Warrant or Warrants, properly endorsed, to the Company at the principal office of the Company, the Company will, subject to the provisions of Section 4 hereof, issue and deliver to or upon the order of such Holder, at the Company’s expense, a new Warrant or Warrants of like tenor, in the name of such Holder or as such Holder (upon payment by such Holder of any applicable transfer taxes) may direct, calling in the aggregate on the face or faces thereof for the number of shares of Warrant Stock called for on the face or faces of the Warrant or Warrants so surrendered.

10. Replacement of Warrants. Upon receipt of evidence reasonably satisfactory to the Company of the loss, theft, destruction or mutilation of this Warrant and (in the case of loss, theft or destruction) upon delivery of an indemnity agreement (with surety if reasonably required) in an amount reasonably satisfactory to the Company, or (in the case of mutilation) upon surrender and cancellation of this Warrant, the Company will issue, in lieu thereof, a new Warrant of like tenor.

11. Mailing of Notices. Any notice required or permitted pursuant to this Warrant shall be in writing and shall be deemed sufficient upon receipt, when delivered personally or sent by courier, three days after deposit with an overnight delivery service, or confirmed facsimile, addressed (a) if to the Holder, to the address of the Holder most recently furnished in writing to the Company; and (b) if to the Company, to the address set forth below or subsequently modified by written notice to the Holder.

12. No Rights as Stockholder. Until the exercise of this Warrant, the Holder of this Warrant shall not have or exercise any rights by virtue hereof as a stockholder of the Company.

13. No Fractional Shares. No fractional shares of Warrant Stock will be issued in connection with any exercise hereunder. In lieu of any fractional shares which would otherwise be issuable, the Company shall pay cash equal to the product of such fraction multiplied by the fair market value of one share of Warrant Stock on the date of exercise, as determined in good faith by the Company’s Board of Directors.

14. Amendment or Waiver. Any term of this Warrant may be amended or waived upon written consent of the Company and the holders of at least a majority of the Warrant Stock issuable upon exercise of outstanding warrants purchased pursuant to the Purchase Agreement. By acceptance hereof, the Holder acknowledges that in the event the required consent is obtained, any

-8-

term of this Warrant may be amended or waived with or without the consent of the Holder; provided, however, that any amendment hereof that would materially adversely affect the Holder in a manner different from the holders of the remaining warrants issued pursuant to the Purchase Agreement shall also require the consent of Holder.

15. Headings. The headings in this Warrant are for purposes of reference only and shall not limit or otherwise affect the meaning of any provision of this Warrant.

16. Governing Law. This Warrant shall be governed, construed and interpreted in accordance with the laws of the State of Delaware, without giving effect to principles of conflicts of law.

17. Counterparts. This Warrant may be executed in counterparts and by facsimile, each of which will be deemed to be an original and all of which together will constitute a single agreement.

The Debtor is the legal and beneficial owner of the Collateral (or, in the case of after-acquired Collateral, at the time the Debtor acquires rights in the Collateral, will be the legal and beneficial owner thereof). Except for the Security Interest granted to the Secured Parties pursuant to this Agreement, the Debtor has rights in or the power to transfer the Collateral free and clear of any adverse Lien, security interest or encumbrance except as created by this Security Interest, except for Permitted Liens. No financing statements covering any Collateral or any proceeds thereof are on file in any public office (other than filings listing the Secured Parties as the secured party).

(b) Valid Security Interest. The Security Interest granted pursuant to this Agreement will constitute a valid and continuing first priority security interest in favor of the Secured Parties in the Collateral for which perfection is governed by the UCC or filing with the United States Copyright Office or United States Patent and Trademark Office. Such Security Interest will be prior to all other Liens on the Collateral, except for Permitted Liens.

(c) Organization and Good Standing. The Debtor has been duly incorporated, and is validly existing and in good standing, under the laws of the State of Delaware.

(d) Location, State of Organization and Name of the Debtor. The Debtor’s state of organization is Delaware and the Debtor’s exact legal name as it appears in the official filings in the State of Delaware is as set forth in the first paragraph of this Agreement. The Debtor has only one jurisdiction of organization.

(e)

Reserved.

(f) Location of Equipment and Inventory. All Equipment and Inventory are (i) located at the locations indicated on Schedule A (ii) in transit to such locations or (iii) in transit to a third party purchaser which will become obligated on a Receivable to the Debtor upon receipt. Except for Equipment and Inventory referred to in clauses (ii) and (iii) of the preceding sentence, the Debtor has exclusive possession and control of the Inventory and Equipment.

(g) Delivery of Items. Schedule B lists all Instruments (other than checks received in the ordinary course of business), letter-of-credit rights, Electronic Chattel paper and Chattel Paper of the Debtor as of the date hereof. The Debtor has delivered to one or more of the Secured Parties, together with all necessary stock powers, endorsements, assignments and other necessary instruments of transfer, the originals of all Receivables consisting of instruments and Chattel Paper and the originals of all certificated securities owned directly by the Debtor.

(h) Receivables. To the best of the Debtor’s knowledge, Receivable is genuine and enforceable against the party obligated to pay the same (an “Account Debtor”) free from any right of rescission, defense, setoff or discount.

(i) Insurance. Each insurance policy maintained by the Debtor is validly existing and is in full force and effect. The Debtor is not in default in any material respect under the provisions of any insurance policy, and there are no facts which, with the giving of notice or passage of time (or both), would result in such a default under any material provision of any such insurance policy.

(j) This Agreement is effective to create a valid and continuing Lien upon the Collateral. All action by the Debtor necessary or desirable to protect and perfect such Lien on each item of the Collateral has been duly taken.

4. Covenants. The Debtor covenants and agrees with the Secured Parties that, from and after the date of this Agreement until the Obligations are paid in full:

(a) Other Liens. Except for the Security Interest and Permitted Liens, the Debtor has rights in or the power to transfer the Collateral and its title and will be able to do so hereafter free from any adverse Lien, security interest or encumbrance, and the Debtor will defend the Collateral against the claims and demands of all persons at any time claiming the same or any interest therein.

(b) Further Documentation. At any time and from time to time, upon the written request of the Secured Parties, and at the sole expense of the Debtor, the Debtor will promptly and duly authenticate and deliver such further instruments and documents and take

such further action as the Secured Parties may reasonably request for the purpose of obtaining or preserving the full benefits of this Agreement and of the rights and powers herein granted including, without limitation, filing any financing or continuation statements under the UCC in effect with respect to the Liens created hereby. The Debtor also hereby authorizes the Secured Parties to file any such financing, amendment or continuation statement without the authentication of the Debtor to the extent permitted by applicable law. A reproduction of this Agreement shall be sufficient as a financing statement (or as an exhibit to a financing statement on form UCC-1) for filing in any jurisdiction.

(c) Indemnification. The Debtor agrees to defend, indemnify and hold harmless the Secured Parties against any and all liabilities, costs and expenses (including, without limitation, legal fees and expenses) (“Liabilities”): (i) with respect to, or resulting from, any delay in paying, any and all excise, sales or other taxes which may be payable or determined to be payable with respect to any of the Collateral, (ii) with respect to, or resulting from, any delay in complying with any law, rule, regulation or order of any governmental authority applicable to any of the Collateral or (iii) in connection with any of the transactions contemplated by this Agreement.

The Debtor agrees to render to the Secured Parties, at the Debtor’s reasonable expense, such clerical and other assistance as the Secured Parties may reasonably request with regard to the exercise of their respective rights pursuant to this paragraph.

(f) Compliance with Laws, etc. The Debtor (i) will comply with all laws, rules, regulations and orders of any governmental authority applicable to any material portion of the Collateral or to the operation of the Debtor’s business, the failure of which to comply with will have a material adverse effect on the Debtor, and (ii) shall not use or permit any Collateral to be used in violation of any provision of the Purchase Agreement and the Notes, any law, rule or obligation or order of any governmental authority, or any policy of insurance covering any material portion of the Collateral; provided, however, that in each case, the Debtor may contest any such law, rule, regulation or order; in any reasonable manner which does not, in the reasonable opinion of the Debtor, adversely affect in any material manner the Secured Parties’ rights or the priority of its Liens on the Collateral.

(g) Payment of Obligations. The Debtor will pay promptly when due all taxes, assessments and governmental charges or levies imposed upon the Collateral or with respect to any its income or profits derived from the Collateral, as well as all claims of any kind

(including, without limitation, claims for labor, materials and supplies) against or with respect to the Collateral.

(h) Limitation on Liens on Collateral. The Debtor will not create, incur or permit to exist, will defend the Collateral against, and will take such other action as is reasonably necessary to remove, any Lien or claim on or to the Collateral, other than the Security Interest and Permitted Liens, and will defend the right, title and interest of the Secured Parties in and to any of the Collateral against the claims and demands of all other persons.

(i) Limitations on Dispositions of Collateral. The Debtor will not sell, transfer, lease, or otherwise dispose of any material portion of the Collateral, or attempt, offer or contract to do so other than dispositions of Inventory in the ordinary course of the Debtor’s business; provided, however that the Debtor will be allowed to grant licenses to its products and related documentation in the ordinary course of business and to establish or provide for escrows of related intellectual property in connection therewith.

(j) Further Identification of Collateral. The Debtor will furnish to the Secured Parties from time to time statements and schedules further identifying and describing the Collateral and such other reports in connection with the Collateral as the Secured Parties may reasonably request.

(k) Notice of Change of State of Incorporation. Without 30 days’ prior written notice to the Secured Parties, the Debtor shall not (i) change the Debtor’s name, state of incorporation or organization, organizational identification number or place of business (or, if the Debtor has more than one place of business, its chief executive office), or the office in which the Debtor’s records relating to Receivables are kept, (ii) keep Collateral consisting of Chattel Paper and documents at any location other than its chief executive office set forth on Schedule B, or (iii) keep Collateral consisting of Equipment, Inventory or other goods at any location other than the locations set forth in Schedule A.

(l) Future Commercial Tort Claims. The Debtor will promptly give notice to the Secured Parties upon the initiation of any Commercial Tort Claim. The Debtor hereby authorizes the Secured Parties to amend this Agreement (without any further action or consent from the Debtor) to include any such Commercial Tort Claim as Collateral hereunder.

(m) Collection of Receivables. The Debtor shall collect, enforce and receive delivery of the Receivables in accordance with past practice until otherwise notified by the Secured Parties.

(p) Letters of Credit. If the Debtor is or becomes the beneficiary of a letter of credit, the Debtor shall promptly, and in any event within two business days after becoming a beneficiary, notify the Secured Parties thereof and enter into a tri-party agreement with the Secured Parties and the issuer or confirmation bank with respect to such Letter of Credit Rights assigning such Letter of Credit Rights to the Secured Parties and directing all payments thereunder to the Secured Parties, all in form and substance reasonably satisfactory to the Secured Parties.

(q) Electronic Chattel Paper. The Debtor shall take all steps reasonably necessary to grant the Secured Parties control of all Electronic Chattel Paper in accordance with the UCC and all “transferable records” as defined in each of the Uniform Electronic Transactions Act and the Electronic Signatures in Global and National Commerce Act.

(r) Intellectual Property Matters. The Debtor shall notify the Secured Parties immediately if it knows or has reason to know (i) that any application or registration relating to any of its Intellectual Property that is material to the operation of its business may become abandoned or dedicated, or (ii) of any adverse determination or development (including the institution of, or any such determination or development in, any proceeding in the United States Patent and Trademark Office, the United States Copyright Office or any court) regarding the Debtor’s ownership of any Intellectual Property that is material to the operation of its business, its right to register the same, or to keep and maintain the same.

If an Event of Default has occurred and is continuing, the Secured Parties may exercise, in addition to all other rights and remedies granted to them in this Agreement and in any other instrument or agreement relating to the Obligations, all rights and remedies of a secured party under the UCC. Without limiting the foregoing, the Secured Parties, without demand of performance or other demand, presentment, protest, advertisement or notice of any kind (except any notice required by law) to or upon the Debtor or any other person (all of which demands, defenses, advertisements and notices are hereby waived), may in such circumstances collect, receive, appropriate and realize upon any or all of the Collateral, and/or may sell, lease, assign, give an option or options to purchase, or otherwise dispose of and deliver any or all of the Collateral (or contract to do any of the foregoing), in one or more parcels at a public or private sale or sales, at any exchange, broker’s board or office of any Secured Party or elsewhere upon such terms and conditions as the Secured Parties may deem advisable, for cash or on credit or for future delivery without assumption of any credit risk. The Secured Parties shall have the right upon any such public sale or sales and, to the extent permitted by law, upon any such private sale or sales, to purchase all or any part of the Collateral so sold, free of any right or equity of redemption in the Debtor, which right or equity is hereby waived or released. The Secured Parties shall apply the net proceeds of any such collection, recovery, receipt, appropriation, realization or sale, after deducting all reasonable expenses incurred therein or in connection with the care or safekeeping of any of the Collateral or in any way relating to the

Collateral or the rights of the Secured Parties under this Agreement (including, without limitation, reasonable attorneys’ fees and expenses) to the payment in whole or in part of the Obligations, in such order as the Secured Parties may elect, and only after such application and after the payment by the Secured Parties of any other amount required by any provision of law, need the Secured Parties account for the surplus, if any, to the Debtor. To the extent permitted by applicable law, the Debtor waives all claims, damages and demands it may acquire against the Secured Parties arising out of the exercise by the Secured Parties of any of their respective rights hereunder. If any notice of a proposed sale or other disposition of Collateral shall be required by law, such notice shall be deemed reasonable and proper if given at least ten days before such sale or other disposition. The Debtor shall remain liable for any deficiency if the proceeds of any sale or other disposition of the Collateral are insufficient to pay the Obligations and the fees and disbursements of any attorneys employed by the Secured Parties to collect such deficiency. In furtherance of the Secured Parties’ rights hereunder, the Debtor hereby grants to the Secured Parties an irrevocable, non-exclusive license (exercisable without royalty or other payment by the Secured Parties) to use, license or sublicense any patent, trademark, tradename, copyright or other Intellectual Property in which the Debtor now or hereafter has any right, title or interest, together with the right of access to all media in which any of the foregoing may be recorded or stored.

8. Limitation on Duties Regarding Preservation of Collateral. Each Secured Party’s sole duty with respect to the custody, safekeeping and preservation of the Collateral, under Section 9207 of the UCC or otherwise, shall be to deal with it in the same manner as such Secured Party deals with similar property for its own account. Neither the Secured Parties nor any of their respective directors, officers, employees or agents shall be liable for failure to demand, collect or realize upon all or any part of the Collateral or for any delay in doing so other than as a result of the gross negligence or willful misconduct of the same or shall be under any obligation to sell or otherwise dispose of any Collateral upon the request of the Debtor or otherwise.

9. Powers Coupled with an Interest. All authorizations and agencies contained in this Agreement with respect to the Collateral are irrevocable and are powers coupled with an interest.

10. No Waiver; Cumulative Remedies. The Secured Parties shall not by any act (except by a written instrument pursuant to Section 12(a) hereof), delay, indulgence, omission or otherwise be deemed to have waived any right or remedy hereunder or to have acquiesced in any default under the Note or in any breach of any of the terms and conditions of this Agreement. No failure to exercise, nor any delay in exercising, on the part of the Secured Parties, any right, power or privilege hereunder shall operate as a waiver thereof. No single or partial exercise of any right, power or privilege hereunder shall preclude any other or further exercise thereof or the exercise of any other right, power or privilege. A waiver by the Secured Parties of any right or remedy under this Agreement on any one occasion shall not be construed as a bar to any right or remedy which the Secured Parties would otherwise have on any subsequent occasion. The rights and remedies provided in this Agreement are cumulative, may be exercised singly or concurrently and are not exclusive of any rights or remedies provided by law.

11. Termination of Security Interest. Upon satisfaction of the Debtor’s obligations pursuant to the Note, or conversion of the Note into shares of the Company’s equity securities pursuant to the terms of the Note, the security interest granted herein shall terminate and all rights to the Collateral shall revert to the Debtor. Upon any such termination, the Secured Parties shall authenticate and deliver to the Debtor such documents as the Debtor may reasonably request to evidence such termination.

12.
