    SECURITY
      AGREEMENT

    

    THIS
      SECURITY AGREEMENT (this “Agreement”)
      is
      made as of May 25, 2006, by
      and
      among U.S. Bank National
      Association, as Collateral Agent for the Purchasers (as that term is defined
      in
      the Securities Purchase Agreement defined below) (together with its successors
      and assigns in such capacity, the “Agent”);
      Nestor, Inc., a Delaware corporation (together with its successors
      and permitted assigns, the “Borrower”);
      and
      Nestor Traffic Systems, Inc., a Delaware corporation, and CrossingGuard, Inc.,
      a
      Delaware corporation (together with their successors and permitted assigns,
      collectively and jointly and severally, the “Subsidiary
      Guarantors”,
      and
      together with the Borrower, collectively and jointly and severally, the
“Grantors”).

    

    Background

    

    The
      Agent, the Borrower and the Purchasers entered into that certain Securities
      Purchase Agreement dated as of May 24, 2006 (as the same may be amended,
      restated, modified, supplemented and/or replaced from time to time, the
“Securities
      Purchase Agreement”),
      pursuant to which the Purchasers agreed to purchase secured convertible
      promissory notes of the Borrower on the terms and conditions described therein.
      The Borrower may, among other things, use the proceeds of the securities
      purchased thereunder to extend credit to, and make capital contributions in,
      the
      Subsidiary Guarantors. Therefore, as a result of the Securities Purchase
      Agreement, the Subsidiary Guarantors can obtain capital on terms more favorable
      to them as part of this borrowing group than they could acting alone. The
      Subsidiary Guarantors have guaranteed the obligations of the Borrower arising
      out of the Securities Purchase Agreement and related agreements and
      instruments.

    

    One
      of
      the conditions to the obligations of the Purchasers under the Securities
      Purchase Agreement is that payment of the Secured Obligations (as defined below)
      shall be secured by, among other things, a security interest in favor of the
      Agent and the Purchasers in the Collateral (as defined below). In order to
      induce the Purchasers to purchase the Notes from the Borrower, the Grantors
      are
      willing to grant to the Agent, for the benefit of the Purchasers, a security
      interest in the Collateral.

    

    Accordingly,
      each Grantor, intending to be legally bound, hereby agrees with the Agent as
      follows:

      of
      New York, has jurisdiction with respect to all, or any portion of, the
      Collateral or this Agreement, from time to time. It is the intent of the parties
      that the definitions set forth above should be construed in their broadest

      there
      are, from time to time, changes to defined terms in the Uniform Commercial

      definitions in the Uniform Commercial Code are broader than the amended

      “as defined in the Uniform Commercial Code, but in any event shall include,
      but
      not be limited to . . .” is used above, it means as defined in the Uniform
      Commercial Code except that if any of the enumerated types of items specified
      thereafter would not fall within the Uniform Commercial Code definition, they
      shall nonetheless be included in the applicable definition for purposes of
      this
      Agreement.

      title and interest in and to all the following property, in all its forms,
      in
      each case whether now or hereafter existing, whether now owned or hereafter
      acquired, created or arising, and wherever located (collectively, but without
      duplication, the “Collateral”):

     

    (a) All
      Equipment;

    

    (b) All
      Inventory and other Goods;

    

    (c) All
      Accounts;

    

    
      
        
        

      

      
        -4-

      8
      attached
      hereto, the licenses for the use of any patents, trademarks, copyrights and

      attached
      hereto;

    Notwithstanding
      the foregoing, contracts entered into by any of the Grantors after
      October 1, 2006 and all assets related thereto and all Proceeds thereof shall

      October 1, 2006 and any and all renewals of or amendments to contracts of any
      of
      the Grantors existing as of the date of this Agreement or entered into on or
      before October 1, 2006 shall be “Collateral” hereunder. Notwithstanding
      the foregoing, nothing herein shall be deemed to constitute an assignment of
      any
      asset which, in the event of an assignment, becomes void by operation of
      applicable Law or the assignment of which (a) is otherwise prohibited by
      applicable Law (in each case to the extent that such applicable Law is not
      overridden by Sections 9-406, 9-407 and/or 9-408 of the Uniform Commercial
      Code
      or other similar applicable Law) or (b) would result in the abandonment,
      invalidation or unenforceability of any right, title or interest of any Grantor
      therein; provided,
      however, that to the extent permitted by applicable Law, this Agreement shall
      create a valid security interest in such asset and, to the extent permitted
      by
      applicable Law, this Agreement shall create a valid security interest in the
      Proceeds of such asset. 

    

    3.  SECURITY
      FOR OBLIGATIONS.

      security interest created hereby in the Collateral constitutes continuing
      collateral security for all of the following obligations, whether now existing
      or hereafter incurred (collectively, the “Secured
      Obligations”):

      unenforceable or is not allowable due to the existence of such Insolvency
      Proceeding), and (B) all fees, commissions, expense reimbursements,
      indemnifications and all other amounts due or to become due under the Securities
      Purchase Agreement or any of the Transaction Documents; and

    (b)  the
      due
      performance and observance by each Grantor of all of its other obligations

      the Secured Obligations. Upon the filing of Uniform Commercial Code financing
      statements in the offices set forth on Schedule
      4
      hereto
      and the recordation of this Agreement (or a short form hereof) at the United
      States Copyright Office and the United States Patent and Trademark Office,
      all
      security interests which may be perfected by filing shall have been duly
      perfected. Except for the filing of the Uniform Commercial Code financing
      statements referred to in the preceding sentence and the delivery of the
      Instruments referred to in paragraph (g) above, no action is necessary to
      create, perfect or protect such security interest. Without limiting the
      generality of the foregoing, except for the filing of said financing statements
      and such recordation and except for customer contracts which may contain
      limitations on assignment, no consent of any third parties and no authorization,
      approval or other action by, and no notice to or filing with any Governmental
      Authority or regulatory body is required for (i) the execution, delivery and
      performance of this Agreement, (ii) the creation or perfection of the security
      interest in the Collateral or (iii) the enforcement of the Agent’s rights
      hereunder.

     

    (j)  Absence
      of Conflicts with Other Agreements, Etc.
      Neither
      the pledge of the Collateral hereunder nor any of the provisions hereof
      (including, without limitation, the remedies provided hereunder) violates any
      of
      the provisions of any Organizational Documents of any Grantor, or any other
      agreement to which any Grantor or any of its property is a party or is subject,
      or any judgment, decree, order or award of any court, governmental body or
      arbitrator or any applicable law, rule or regulation applicable to the
      same.

     

    (k)  Account
      Debtors.
      None of
      the account debtors or other Persons obligated on any of the Collateral is
      a
      Governmental Authority covered by the Federal Assignment of Claims Act or any
      similar federal, state or local statute or rule in respect of such
      Collateral.

    (l)  Intellectual
      Property.
      Schedules
      5, 6, 7 and 8
      list all
      of the patents, patent applications, trademarks, trademark applications,
      registered copyrights, and domain names owned by any of the Grantor as of the
      date hereof. Schedule
      9
      lists
      all licenses in favor of any Grantor for the use of any patents, trademarks,
      copyrights and domain names as of the date hereof other than commercial
      off-the-shelf software. All material patents and trademarks of the Grantors
      have
      been duly recorded at the United States Patent and Trademark Office. The
      Grantors have no material copyrights, whether or not recorded at the United
      States Copyright Office.

     

    5.  COVENANTS
      OF GRANTORS.
      Each
      Grantor covenants that:

     

    (a)  Filing
      of Financing Statements and Preservation of Interests.
      Immediately upon execution hereof, each Grantor shall file (i) in each office
      set forth on Schedule
      4
      Uniform
      Commercial Code financing statements and (ii) all filings with the United States
      Copyright Office and the United States Patent and Trademark Office, including
      an
      intellectual property collateral agreement in favor of the Agent, pursuant
      to
      which each Grantor shall grant to the Agent for the benefit of the Purchasers
      a
      security interest in all of its service marks, trademarks and trade names and
      the goodwill associated therewith, and in all of its patents, patent
      applications and patent license agreements, as therein provided, in each case
      in
      form and substance satisfactory to the Agent. Without limiting the obligation
      of
      the Grantors set forth in the preceding sentence, each Grantor hereby authorizes
      the Agent, and appoints the Agent as its attorney-in-fact, to file in such
      office or offices as the Agent deems necessary or desirable such financing
      and
      continuation statements and amendments and supplements thereto (including,
      without limitation, an “all assets” filing), and such other documents as the
      Agent may require to perfect, preserve and protect the security interests
      granted herein and ratifies all such actions taken by the Agent. Each Grantor
      also ratifies its authorization for the Lender to have filed in any jurisdiction
      any like initial financing statements or amendments thereto filed prior to
      the
      date of this Agreement.

     

    (b)  Delivery
      of Instruments, Etc.
      At any
      time and from time to time that any Collateral consists of Instruments,
      certificated securities or other items that require or permit possession by
      the
      secured party to perfect the security interest created hereby, the applicable
      Grantor shall deliver such Collateral to the Agent.

     

    (c)  Chattel
      Paper.
      Each
      Grantor shall cause all Chattel Paper constituting Collateral to be delivered
      to
      the Agent, or, if such delivery is not possible, then to cause such Chattel
      Paper to contain a legend noting that it is subject to the security interest
      created by this Agreement. To the extent that any Collateral consists of
      electronic Chattel Paper, the applicable Grantor shall cause the underlying
      Chattel Paper to be “marked” within the meaning of Section 9-105 of the Uniform
      Commercial Code (or successor section thereto).

     

    (d)  Investment
      Property and Deposit Accounts.
      If
      there are any Investment Property or Deposit Accounts included as Collateral
      that can be perfected by “control” through an account control agreement, the
      applicable Grantor shall cause such an account control agreement, in form and
      substance in each case satisfactory to the Agent, to be entered into and
      delivered to the Agent.

     

    
      
        
        

      

      
        -8-

        
          

        

      

      
        
        

      

    

    (e)  Letter-of-Credit
      Rights.
      To the
      extent that any Collateral consists of Letter-of-Credit Rights, the applicable
      Grantor shall cause the issuer of each underlying letter of credit to consent
      to
      the assignment to the Agent.

     

    (f)  Collateral
      In Possession of Third Parties.
      To the
      extent that any Collateral is in the possession of any third party other than
      agencies of state and local governments or except in the ordinary course of
      business, the applicable Grantor shall join with the Agent in notifying such
      third party of the Agent’s security interest and shall make commercially
      reasonable efforts to obtain an acknowledgement from such third party that
      it is
      holding the Collateral for the benefit of the Agent.

     

    (g)  Commercial
      Tort Claims.
      If any
      Grantor shall at any time hold or acquire a Commercial Tort Claim, such Grantor
      shall promptly notify the Agent in a writing signed by such Grantor of the
      particulars thereof and grant to the Agent in such writing a security interest
      therein and in the proceeds thereof, all upon the terms of this Agreement,
      with
      such writing to be in form and substance satisfactory to the Agent.

     

    (h)  Notice
      of Changes in Representations.
      Each
      Grantor shall notify the Agent in advance of any event or condition which could
      cause any representations set forth in Section 4 above applicable to such
      Grantor to fail to be true, correct and complete. Without limiting the
      generality of the foregoing:

     

    (i)  without
      providing at least thirty (30) days prior written notice to the Agent, no
      Grantor will change its name in any respect, its place of business or, if more
      than one, chief executive office, or its mailing address or organizational
      identification number (if it has one);

     

    (ii)  if
      any
      Grantor does not have an organizational identification number and obtains one
      after the date of this Agreement, such Grantor will forthwith notify the Agent
      in writing of such organizational identification number; and

     

    (iii)  no
      Grantor will change its type of organization, jurisdiction of organization
      or
      other legal structure without prior written notice to the Agent.

     

    (i)  Use
      and Condition of Equipment.
      Each
      item of Equipment will be maintained in good repair, working order and
      condition, ordinary wear and tear excepted, and the applicable Grantor will
      provide all maintenance service and repairs necessary for such purpose. The
      Agent may examine and inspect the Collateral at any reasonable time or times
      wherever located.

     

    
      
        
        

      

      
        -9-

        
          

        

      

      
        
        

      

    

    (j)  Insurance.
      Each
      Grantor shall maintain with financially sound and reputable insurers, insurance
      with respect to the Collateral against loss or damage of the kinds and in the
      amounts customarily insured against by entities of established reputation having
      similar properties similarly situated and in such amounts as are customarily
      carried under similar circumstances by other such Persons and otherwise as
      is
      prudent for Persons engaged in similar businesses. Each Grantor shall cause
      each
      insurance policy issued in connection herewith to provide, and the insurer
      issuing such policy to certify to the Agent that (a) the Agent will be named
      as
      lender loss payee and additional insured under each such insurance policy;
      (b)
      if such insurance be proposed to be cancelled or materially changed for any
      reason whatsoever, such insurer will promptly notify the Agent and such
      cancellation or change shall not be effective as to the Agent for at least
      thirty (30) days after receipt by the Agent of such notice, unless the effect
      of
      such change is to extend or increase coverage under the policy; and (c) the
      Agent will have the right (but no obligation) at its election to remedy any
      default in the payment of premiums within thirty (30) days of notice from the
      insurer of such default. Unless the Securities Purchase Agreement or the Notes
      expressly provides otherwise, the following sentence will control application
      of
      proceeds. If no Event of Default exists, loss payments in each instance will
      be
      applied by the applicable Grantor to the repair and/or replacement of property
      with respect to which the loss was incurred to the extent reasonably feasible,
      and any loss payments or the balance thereof remaining, to the extent not so
      applied, shall be payable to the applicable Grantor, provided,
      however, that payments received by any Grantor after an Event of Default occurs
      and is continuing shall be paid to the Agent and, if received by such Grantor,
      shall be held in trust for and immediately paid over to the Agent unless
      otherwise directed in writing by the Agent. Copies of such policies or the
      related certificates, in each case, naming the Agent as lender loss payee shall
      be delivered to the Agent at least annually and at the time any new policy
      of
      insurance is issued.

     

    (k)  Transfer
      of Collateral.
      Other
      than the disposition of inventory and licensing of Intellectual Property in
      the
      ordinary course of the applicable Grantor’s business as presently conducted or
      as otherwise permitted under the terms of the Securities Purchase Agreement,
      no
      Grantor shall sell, assign, transfer, encumber or otherwise dispose of any
      Collateral in excess of $25,000 per year without the prior written consent
      of
      the Agent and the Agent does not authorize any such disposition. For purposes
      of
      this provision, “dispose of any Collateral” shall include, without limitation,
      the creation of a security interest or other encumbrance (whether voluntary
      or
      involuntary) on such Collateral, except for Permitted Liens (as defined in
      the
      Notes).

     

    (l)  Taxes
      and Assessments.
      Each
      Grantor shall promptly pay when due and payable, all taxes and assessments
      imposed upon the Collateral or operations or business of such
      Grantor.

     

    (m)  Inventory.
      No
      Grantor shall return any Inventory to the supplier thereof, except for damaged
      or unsalable Inventory or otherwise in the ordinary course of such Grantor’s
      business. Without limiting the generality of the foregoing, in the event any
      Grantor becomes a “debtor in possession” as defined in 11 U.S.C. §1101 (or any
      successor thereto), such Grantor agrees, to the extent permitted by applicable
      Law, not to move pursuant to 11 U.S.C. §546 (or any successor thereto) for
      permission to return goods to any creditor which shipped such goods to such
      Grantor without the Agent’s written consent and each Grantor hereby waives any
      rights to return such Inventory arising under 11 U.S.C. §546(h), or any
      successor section thereto.

     

    
      
        
        

      

      
        -10-

        
          

        

      

      
        
        

      

    

    (n)  Defense
      of Agent’s Rights.
      Each
      Grantor warrants and will defend the Agent’s right, title and security interest
      in and to the Collateral against the claims of any Person.

     

    (o)  Cash
      Management.
      At any
      time following an Event of Default that the Agent so requests, the Grantors
      will
      work with the Agent to set up such lock boxes and segregated accounts as the
      Agent may request in order to better perfect the security interest created
      hereunder in Proceeds.

     

    (p)  Additional
      Grantors.
      Each
      Grantor shall cause each Subsidiary of such Grantor including (i) any Person
      that shall at any time become a Subsidiary of such Grantor, and (ii) Nestor
      Interactive, Inc. (“NII”),
      if at
      any time after the date of this Agreement NII ceases to be inactive or has
      significant assets other than net operating losses, to immediately become a
      party hereto (an “Additional
      Grantor”)
      or to
      a similar security agreement, as appropriate, by executing and delivering an
      Additional Grantor Joinder in substantially the form of Annex
      A
      attached
      hereto and comply with the provisions hereof applicable to the Grantors or
      by
      signing a similar security agreement. If the Additional Grantor becomes a party
      hereto, concurrent therewith, the Additional Grantor shall deliver replacement
      schedules for, or supplements to all other Schedules to (or referred to in)
      this
      Agreement, as applicable, which replacement schedules shall supersede, or
      supplements shall modify, the Schedules then in effect. The Additional Grantor
      shall also deliver such opinions of counsel, authorizing resolutions, good
      standing certificates, incumbency certificates, Organizational Documents,
      financing statements and other information and documentation as the Agent may
      reasonably request. Upon delivery of the foregoing to the Agent, the Additional
      Grantor shall be and become a party to this Agreement with the same rights
      and
      obligations as the Grantors, for all purposes hereof as fully and to the same
      extent as if it were an original signatory hereto and shall be deemed to have
      made the representations, warranties and covenants set forth herein as of the
      date of execution and delivery of such Additional Grantor Joinder and thereafter
      at any time that such representations and covenants must be restated pursuant
      to
      the terms of the Transaction Documents, and all references herein to the
“Grantors” shall be deemed to include each Additional Grantor.

     

    (q)  Inspections.
      Upon
      reasonable notice to the Grantors (and for this purpose no more than two
      business days’ notice shall be required under any circumstances) if
      no
      Event of Default shall exist, and at any time with or without notice after
      the
      occurrence of an Event of Default, each
      Grantor will permit the Agent, or its designee, to inspect the Collateral,
      wherever located, and to discuss the affairs, business, finances and accounts
      of
      the Grantors with their personnel and accountants.
      In the
      event that no Event of Default exists and is continuing, such inspections shall
      not be held more than twice in any six-month period. For the sake of clarity,
      during any time when an Event of Default shall exist and is continuing, the
      Agent may conduct an unlimited number of inspections, subject to the first
      sentence of this Section 5(q). The Agent acknowledges that such inspections
      and
      discussions may result in the Agent, or its designee, receiving material
      nonpublic information. The Agent shall, and shall cause its designee, to keep
      confidential such information as is specifically marked or otherwise identified
      as material nonpublic information by the Grantors.

     

    (r)  Intellectual
      Property.
      Without
      limiting the generality of the other obligations of the Grantors hereunder,
      each
      Grantor shall promptly (i) cause to be registered at the United States Copyright
      Office all of its material copyrights and shall cause the security interest
      contemplated hereby with respect to such copyrights to be duly recorded at
      such
      office, (ii) cause the security interest contemplated hereby with respect to
      all
      Intellectual Property registered at the United States Copyright Office or United
      States Patent and Trademark Office to be duly recorded at the applicable office,
      and (iii) give the Agent notice whenever it acquires (whether absolutely or
      by
      license) or creates any additional material Intellectual Property.

     

    
      
        
        

      

      
        -11-

        
          

        

      

      
        
        

      

    

    (s)  Power
      of Attorney.
      Each
      Grantor has duly executed and delivered to the Agent a power of attorney (a
      “Power
      of Attorney”)
      in
      substantially the form attached hereto as Annex
      B.
      The
      power of attorney granted pursuant to the Power of Attorney is a power coupled
      with an interest and shall be irrevocable until full and indefeasible payment
      of
      the Secured Obligations. The powers conferred on the Agent (for the benefit
      of
      the Agent and the Purchasers) under the Power of Attorney are solely to protect
      the Agent’s interests (for the benefit of the Agent and the Purchasers) in the
      Collateral and shall not impose any duty upon the Agent or any Purchaser to
      exercise any such powers. The Agent agrees that (i) except for the powers
      granted in clause (i) of the Power of Attorney, it shall not exercise any power
      or authority granted under the Power of Attorney unless an Event of Default
      has
      occurred and is continuing, and (ii) the Agent shall account for any moneys
      received by the Agent in respect of any foreclosure on or disposition of
      Collateral pursuant to the Power of Attorney provided that none of the Agent
      or
      any Purchaser shall have any duty as to any Collateral, and the Agent and the
      Purchasers shall be accountable only for amounts that they actually receive
      as a
      result of the exercise of such powers. NONE OF THE AGENT, THE PURCHASERS OR
      THEIR RESPECTIVE AFFILIATES, OFFICERS, DIRECTORS, EMPLOYEES, AGENTS OR
      REPRESENTATIVES SHALL BE RESPONSIBLE TO THE GRANTORS FOR ANY ACT OR FAILURE
      TO
      ACT UNDER ANY POWER OF ATTORNEY OR OTHERWISE, EXCEPT IN RESPECT OF DAMAGES
      ATTRIBUTABLE SOLELY TO THEIR OWN GROSS NEGLIGENCE OR WILLFUL MISCONDUCT AS
      FINALLY DETERMINED BY A COURT OF COMPETENT JURISDICTION, NOR FOR ANY PUNITIVE,
      EXEMPLARY, INDIRECT OR CONSEQUENTIAL DAMAGES.

     

    (t)  Other
      Assurances.
      Each
      Grantor agrees that from time to time, at the joint and several expense of
      the
      Grantors and any Additional Grantors, it will promptly execute and deliver
      all
      such further instruments and documents, and take all such further action as
      may
      be necessary or desirable, or as the Agent may reasonably request, in order
      to
      perfect and protect any security interest granted or purported to be granted
      hereby or to enable the Agent to exercise and enforce its rights and remedies
      hereunder and with respect to any Collateral or to otherwise carry out the
      purposes of this Agreement.

     

    6.  REMEDIES
      UPON EVENT OF DEFAULT.

     

    (a)  Upon
      the
      occurrence and during the continuation of an Event of Default, the Agent may
      exercise, in addition to any other rights and remedies provided herein, under
      other contracts and under law, all the rights and remedies of a secured party
      under the Uniform Commercial Code. Without limiting the generality of the
      foregoing, upon the occurrence and during the continuation of an Event of
      Default, (i) at the request of the Agent, each Grantor shall, at its cost and
      expense, assemble the Collateral owned or used by it as directed by the Agent;
      (ii) the Agent shall have the right (but not the obligation) to notify any
      account debtors and any obligors under Instruments or Accounts to make payments
      directly to the Agent and to enforce the Grantors’ rights against account
      debtors and obligors; (iii) the Agent may (but is not obligated to), without
      notice except as provided below, sell the Collateral at public or private sale,
      on such terms as the Agent deems to be commercially reasonable; (iv) the Agent
      may (but is not obligated to) direct any financial intermediary or any other
      Person holding Investment Property to transfer the same to the Agent or its
      designee; and (v) the Agent may (but is not obligated to) transfer any or all
      Intellectual Property registered in the name of any Grantor at the United States
      Patent and Trademark Office and/or Copyright Office into the name of the Agent
      or any designee or any purchaser of any Collateral. Each Grantor agrees that
      ten
      (10) days notice of any sale referred to in clause (iii) above shall constitute
      sufficient notice. The Agent or any Purchaser may purchase Collateral at any
      such sale. The Grantors shall be liable to the Agent and the Purchasers for
      any
      deficiency amount.

     

    
      
        
        

      

      
        -12-

        
          

        

      

      
        
        

      

    

    (b)  The
      Agent
      may comply with any applicable Law in connection with a disposition of
      Collateral and compliance will not be considered adversely to affect the
      commercial reasonableness of any sale of the Collateral. The Agent may sell
      the
      Collateral without giving any warranties and may specifically disclaim such
      warranties. If the Agent sells any of the Collateral on credit, the Borrower
      will only be credited with payments actually made by the purchaser. In
      addition, each Grantor waives any and all rights that it may have to a judicial
      hearing in advance of the enforcement of any of the Agent’s rights and remedies
      hereunder, including, without limitation, its right following an Event of
      Default to take immediate possession of the Collateral and to exercise its
      rights and remedies with respect thereto.

     

    (c)  For
      the
      purpose of enabling the Agent to further exercise rights and remedies under

    7.  OBLIGATIONS
      ABSOLUTE.

     

    (a)  Change
      of Circumstance.
      THE
      RIGHTS OF THE AGENT HEREUNDER AND THE OBLIGATIONS OF THE GRANTORS HEREUNDER
      SHALL BE ABSOLUTE AND UNCONDITIONAL, SHALL NOT BE SUBJECT TO ANY COUNTERCLAIM,
      SETOFF, RECOUPMENT OR DEFENSE BASED UPON ANY CLAIM THAT ANY GRANTOR OR ANY
      OTHER
      PERSON MAY HAVE AGAINST ANY PURCHASER AND SHALL REMAIN IN FULL FORCE AND EFFECT
      UNTIL FULL AND INDEFEASIBLE SATISFACTION OF THE SECURED OBLIGATIONS AFTER OR
      CONCURRENT WITH THE TERMINATION OF ANY COMMITMENT OF THE PURCHASERS PURSUANT
      TO
      THE SECURITIES PURCHASE AGREEMENT. Without limiting the generality of the
      foregoing, the obligations of the Grantors shall not be released, discharged
      or
      in any way affected by any circumstance or condition (whether or not the
      applicable Grantor shall have any notice or knowledge thereof) including,
      without limitation, any amendment or modification of or supplement to the
      Securities Purchase Agreement, any Notes or any other Transaction Document
      (including, without limitation, increasing the amount or extending the maturity
      of the Secured Obligations); any waiver, consent, extension, indulgence or
      other
      action or inaction under or in respect of any such agreements or instruments,
      or
      any exercise or failure to exercise of any right, remedy, power or privilege
      under or in respect of any such agreements or instruments, or any exercise
      or
      failure to exercise of any right, remedy, power or privilege under or in respect
      of any such agreements or instruments; any invalidity or unenforceability,
      in
      whole or in part, of any term hereof or of the Securities Purchase Agreement,
      any Notes or any other Transaction Document; any failure on the part of Borrower
      or any other Person for any reason to perform or comply with any term of the
      Securities Purchase Agreement, any Note or any other Transaction Document;
      any
      furnishing or acceptance of any additional security or guaranty; any release
      of
      any Grantor or any other Person or any release of any or all security or any
      or
      all guarantees for the Secured Obligations, whether any such release is granted
      in connection with a bankruptcy or otherwise; any bankruptcy, insolvency,
      reorganization, arrangement, readjustment, composition, liquidation or similar
      proceeding with respect to any Grantor or any other Person or their respective
      properties or creditors; the application of payments received by the Agent
      or
      any Purchaser from any source that were lawfully used for some other purpose,
      which lawfully could have been applied to the payment, in full or in part,
      of
      the Secured Obligations; or any other occurrence whatsoever, whether similar
      or
      dissimilar to the foregoing. Without limiting the generality of the foregoing,
      at any time that the Securities Purchase Agreement or the Notes are amended
      to
      increase the amount of the Obligations thereunder, the amount of the Secured
      Obligations shall be accordingly increased.

     

    (b)  No
      Duty To Marshal Assets.
      The
      Agent shall have no obligation to marshal any assets in favor of any Grantor
      or
      any other Person or against or in payment of any or all of the Secured
      Obligations.

     

    (c)  Waiver
      of Right of Subrogation, Etc.
      Each
      Grantor hereby waives any and all rights of subrogation, reimbursement, or
      indemnity whatsoever in respect of such Grantor arising out of remedies
      exercised by the Agent hereunder until full and indefeasible payment of the
      Secured Obligations.

     

    
      
        
        

      

      
        -14-

        
          

        

      

      
        
        

      

    

    (d)  Other
      Waivers.
      Each
      Grantor hereby waives promptness, diligence and notice of acceptance of this
      Agreement. In connection with any sale or other disposition of Collateral,
      to
      the extent permitted by applicable Law, each Grantor waives any right of
      redemption or equity of redemption in the Collateral. Each Grantor further
      waives presentment and demand for payment of any of the Secured Obligations,
      protest and notice of protest, dishonor and notice of dishonor or notice of
      default or any other similar notice with respect to any of the Secured
      Obligations, and all other similar notices to which any Grantor might otherwise
      be entitled, except as otherwise expressly provided in the Transaction
      Documents. The Agent is under no obligation to pursue any rights against third
      parties with respect to the Secured Obligations and each Grantor hereby waives
      any right it may have to require otherwise. Each Grantor (to the extent that
      it
      may lawfully do so) covenants that it shall not at any time insist upon or
      plead, or in any manner claim or take the benefit of, any stay, valuation,
      appraisal or redemption now or at any time hereafter in force that, but for
      this
      waiver, might be applicable to any sale made under any judgment, order or decree
      based on this Agreement; and each Grantor (to the extent that it may lawfully
      do
      so) hereby expressly waives and relinquishes all benefit of any and all such
      laws and hereby covenants that it will not hinder, delay or impede the execution
      of any power in this Agreement delegated to the Agent, but that it will suffer
      and permit the execution of every such power as though no such law or laws
      had
      been made or enacted.

     

    (e)  Each
      Grantor further waives to the fullest extent permitted by law any right it
      may
      have under the constitution of the State of New York (or under the constitution
      of any other state in which any of the Collateral or any Grantor may be
      located), or under the Constitution of the United States of America, to notice
      (except for notice specifically required hereby) or to a judicial hearing prior
      to the exercise of any right or remedy provided by this Agreement to the Agent,
      and waives its rights, if any, to set aside or invalidate any sale duly
      consummated in accordance with the foregoing provisions hereof on the grounds
      (if such be the case) that the sale was consummated without a prior judicial
      hearing.

     

    (f)  EACH
      GRANTOR’S WAIVERS UNDER THIS SECTION 7 HAVE BEEN MADE VOLUNTARILY, INTELLIGENTLY
      AND KNOWINGLY AND AFTER SUCH GRANTOR HAS BEEN APPRISED AND COUNSELED BY ITS
      ATTORNEY AS TO THE NATURE THEREOF AND ITS POSSIBLE ALTERNATIVE
      RIGHTS.

     

    8.  NO
      IMPLIED WAIVERS.
      No
      failure or delay on the part of the Agent in exercising any right, power or
      privilege under this Agreement or the other Transaction Documents and no course
      of dealing between the Grantor, on the one hand, and the Agent or the
      Purchasers, on the other hand, shall operate as a waiver of any such right,
      power or privilege. No single or partial exercise of any right, power or
      privilege under this Agreement or the other Transaction Documents precludes
      any
      other or further exercise of any such right, power or privilege or the exercise
      of any other right, power or privilege. The rights and remedies expressly
      provided in this Agreement and the other Transaction Documents are cumulative
      and not exclusive of any rights or remedies which the Agent or the Purchasers
      would otherwise have. No notice to or demand on any Grantor in any case shall
      entitle the Grantors to any other or further notice or demand in similar or
      other circumstances or shall constitute a waiver of the right of the Agent
      or
      the Purchasers to take any other or further action in any circumstances without
      notice or demand. Any waiver that is given shall be effective only if in writing
      and only for the limited purposes expressly stated in the applicable
      waiver.

     

    
      
        
        

      

      
        -15-

        
          

        

      

      
        
        

      

    

    9.  STANDARD
      OF CARE.

     

    (a)  In
      General.
      No act
      or omission of the Agent or any Purchaser (or agent or employee of any of the
      foregoing) hereunder or related hereto or related to the transactions
      contemplated by this Agreement or the other Transaction Documents shall give
      rise to any defense, counterclaim or offset in favor of any Grantor or any
      claim
      or action against the Agent or such Purchaser (or agent or employee thereof),
      in
      the absence of gross negligence or willful misconduct of the Agent or such
      Purchaser (or agent or employee thereof) as determined in a final, nonappealable
      judgment of a court of competent jurisdiction. The Agent shall be deemed to
      have
      exercised reasonable care in the custody and preservation of the Collateral
      in
      its possession if the Collateral is accorded treatment substantially equal
      to
      that which the Agent accords to other Collateral it holds, it being understood
      that it has no duty to take any action with respect to calls, conversions,
      exchanges, maturities, tenders or other matters relative to any Collateral
      or to
      preserve any rights of any parties and shall only be liable for losses which
      are
      a result of it gross negligence or willful misconduct as determined in a final,
      nonappealable judgment of a court of competent jurisdiction.

     

    (b)  No
      Duty to Preserve Rights.
      Without
      limiting the generality of the foregoing, the Agent has no duty (either before
      or after an Event of Default) to collect any amounts in respect of the
      Collateral or to preserve any rights relating to the Collateral.

     

    (c)  No
      Duty to Prepare for Sale.
      Without
      limiting the generality of the foregoing, the Agent has no obligation to
      clean-up or otherwise prepare the Collateral for sale.

     

    (d)  Duties
      Relative to Contracts.
      Without
      limiting the generality of the foregoing, each Grantor shall remain obligated
      and liable under each contract or agreement included in the Collateral to be
      observed or performed by such Grantor thereunder. The Agent shall not have
      any
      obligation or liability under any such contract or agreement by reason of or
      arising out of this Agreement or the receipt by the Agent of any payment
      relating to any of the Collateral, nor shall the Agent be obligated in any
      manner to perform any of the obligations of any Grantor under or pursuant to
      any
      such contract or agreement, to make inquiry as to the nature or sufficiency
      of
      any payment received by the Agent in respect of the Collateral or as to the
      sufficiency of any performance by any party under any such contract or
      agreement, to present or file any claim, to take any action to enforce any
      performance or to collect the payment of any amounts which may have been
      assigned to the Agent or to which the Agent may be entitled at any time or
      times.

     

    (e)  Reliance
      on Advice of Counsel.
      In
      taking any action under this Agreement or any other Transaction Document, the
      Agent shall be entitled to rely upon the advice of counsel of Agent’s choice and
      shall be fully protected in acting on such advice whether or not the advice
      rendered is ultimately determined to have been accurate.

     

    
      
        
        

      

      
        -16-

        
          

        

      

      
        
        

      

    

    (f)  No
      Obligation to Act.
      The
      Agent shall be entitled to act or to refrain from acting (and shall be fully
      protected in so acting or refraining from acting) upon the written instructions
      of the Required Holders (as defined below) and such instructions shall be
      binding upon all the Purchasers; provided,
      however,
      that the
      Agent shall not be under any obligation to exercise any of the rights or powers
      vested in it by this Agreement or any Security Document in the manner so
      requested unless, if so requested by the Agent, it shall have been provided
      indemnity from the Borrower satisfactory to it against the costs, expenses
      and
      liabilities which may be incurred by it in compliance with or in performing
      such
      request or direction. No provisions of this Agreement or any Security Document
      shall otherwise be construed to require the Agent to expend or risk its own
      funds or take any action that could in its judgment cause it to incur any cost,
      expenses or liability for which it is not specifically indemnified hereunder
      or
      under the Securities Purchase Agreement. No provision of this Agreement or
      of
      any Security Document shall be deemed to impose any duty or obligation on the
      Agent to perform any act or acts or exercise any right, power, duty or
      obligation conferred or imposed on it, in any jurisdiction in which it shall
      be
      illegal, or in which the Agent shall be unqualified or incompetent, to perform
      any such act or acts or to exercise any such right, power, duty or obligation
      or
      if such performance or exercise would constitute doing business by the Agent
      in
      such jurisdiction or impose a tax on the Agent by reason thereof.

     

    (g)  Action
      By Agent.
      Absent
      written instructions from the Required Holders at a time when an Event of
      Default shall have occurred and be continuing, the Agent shall have no
      obligation to take any actions under the Security Documents.

     

    10.  MISCELLANEOUS.

     

    (a)  Assignment.
      Except
      as otherwise provided in the Securities Purchase Agreement, the Agent and each
      Purchaser may assign or transfer this Agreement and any or all rights or
      obligations hereunder without the consent of any Grantor and without prior
      notice. No Grantor shall assign or transfer this Agreement or any rights or
      obligations hereunder without the prior written consent of the Agent or as
      expressly provided in the Securities Purchase Agreement. Notwithstanding
      the foregoing, if there should be any assignment of any rights or obligations
      by
      operation of law or in contravention of the terms of this Agreement or
      otherwise, then all covenants, agreements, representations and warranties made
      herein or pursuant hereto by or on behalf of any Grantor shall bind the
      successors and assigns of such Grantor, together with the preexisting Grantor,
      whether or not such new or additional Persons execute a joinder hereto or
      assumption hereof (without the same being deemed a waiver of any default caused
      thereby) which condition shall not be deemed to be a waiver of any Event of
      Default arising out of such assignment.
      The
      rights and privileges of the Agent under this Agreement shall inure to the
      benefit of its successors and assigns.

     

    (b)  Joint
      and Several Liability.
      All
      Grantors shall jointly and severally be liable for the obligations of each
      Grantor to the Agent and the Purchasers hereunder.

     

    (c)  Notices.
      All
      notices, requests, demands, directions and other communications provided for
      herein shall be in writing and shall be delivered or mailed in the manner
      specified in the Securities Purchase Agreement addressed to a party at its
      address set forth in or determined pursuant to the Securities Purchase
      Agreement, as the case may be.

     

    
      
        
        

      

      
        -17-

        
          

        

      

      
        
        

      

    

    (d)  Severability.
      Every
      provision of this Agreement is intended to be severable. If any term or
      provision of this Agreement shall be invalid, illegal or unenforceable for
      any
      reason, the validity, legality and enforceability of the remaining provisions
      shall not be affected or impaired thereby. Any invalidity, illegality or
      unenforceability in any jurisdiction shall not affect the validity, legality
      or
      enforceability of any such term or provision in any other
      jurisdiction.

     

    (e)  Costs
      and Expenses.
      Without
      limiting any other cost reimbursement provisions in the Transaction Documents,
      upon demand, the
      Grantors shall pay to
      the
      Agent and the Purchasers, as applicable, the amount of any and all reasonable
      expenses incurred by the Agent and the Purchasers hereunder or in connection
      herewith, including, without limitation, reasonable fees of counsel to the
      Agent
      and the Purchasers and those other expenses that may be incurred in connection
      with (i) the execution and delivery of this Agreement and any amendments,
      waivers and supplements hereto, (ii) the administration of this Agreement,
      (iii)
      the custody or preservation of, or the sale of, collection from, or other
      realization upon, any of the Collateral, (iv) the exercise or enforcement of
      any
      of the rights of the Agent or the Purchasers hereunder or (v) the failure of
      any
      Grantor to perform or observe any of the provisions hereof.

     

    (f)  Indemnification
      by Grantors.
      Each
      Grantor shall indemnify, reimburse and hold harmless all Indemnitees from and
      against any and all losses, claims, liabilities, damages, penalties, suits,
      costs and expenses, of any kind or nature, (including fees relating to the
      cost
      of investigating and defending any of the foregoing) imposed on, incurred by
      or
      asserted against such Indemnitee in any way related to or arising from or
      alleged to arise from this Agreement or the Collateral, except any such losses,
      claims, liabilities, damages, penalties, suits, costs and expenses which result
      from the gross negligence or willful misconduct of the Indemnitee as determined
      by a final nonappealable decision of a court of competent jurisdiction. This
      indemnification provision is in addition to, and not in limitation of, any
      other
      indemnification provision in any other Transaction Document.

     

    (g)  Counterparts;
      Integration.
      This
      Agreement may be executed in counterparts (and by different parties hereto
      in
      different counterparts), each of which shall constitute an original, but all
      of
      which when taken together shall constitute a single contract. This Agreement
      and
      the other Transaction Documents constitute the entire contract among the parties
      relating to the subject matter hereof and supersede any and all previous
      agreements and understandings, oral or written, relating to the subject matter
      hereof. Delivery of an executed counterpart of a signature page of this
      Agreement by telecopy shall be effective as delivery of a manually executed
      counterpart of this Agreement.

     

    (h)  Amendments
      and Waivers. The
      Purchasers holding 75% of the total outstanding principal balance of the Notes
      (the “Required
      Holders”)
      shall
      have the right to direct the Agent, from time to time, to consent to any
      amendment, modification or supplement to or waiver of any provision of this
      Agreement and to release any Collateral from any lien or security interest
      held
      by the Agent; provided,
      however,
      that
      (i) no such direction shall require the Agent to consent to the modification
      of
      any provision or portion thereof which (in the sole judgment of the Agent)
      is
      intended to benefit the Agent, (ii) the Agent shall have the right to decline
      to
      follow any such direction if the Agent shall determine in good faith that the
      directed action is not permitted by the terms of this Agreement or may not
      lawfully be taken and (iii) no such direction shall waive or modify any
      provision of this Agreement the waiver or modification of which requires the
      consent of all Purchasers unless all Purchasers consent thereto. The Agent
      may
      rely on any such direction given to it by the Required Holders and shall be
      fully protected in relying thereon, and shall under no circumstances be liable,
      except in circumstances involving the Agent's gross negligence or willful
      misconduct as shall have been determined in a final nonappealable judgment
      of a
      court of competent jurisdiction, to any holder of the Notes or any other person
      or entity for taking or refraining from taking action in accordance with any
      direction or otherwise in accordance with this Agreement.

     

    
      
        
        

      

      
        -18-

        
          

        

      

      
        
        

      

    

    (i)  Headings.
      Headings to this Agreement are for purposes of reference only and shall not
      limit or otherwise affect the meaning hereof

     

    11.  SPECIFIC
      PERFORMANCE.
      Each
      Grantor hereby authorizes the Agent to demand specific performance of this
      Agreement at any time when any Grantor shall have failed to comply with any
      provision hereof, and each Grantor hereby irrevocably waives any defense based
      on the adequacy of a remedy at law which might be asserted as a bar to the
      remedy of specific performance hereof in any action brought therefor. Each
      Grantor that is not a party to the Securities Purchase Agreement hereby
      acknowledges receipt from the Borrower of a correct and complete copy of the
      Securities Purchase Agreement and consents to all of the provisions of the
      Securities Purchase Agreement as in effect on the date hereof and agrees that
      its consent is not required for any amendments, modifications, restatements
      or
      waivers of it or any of the provisions thereof.

     

    12.  RELATIONSHIP
      WITH SECURITIES PURCHASE AGREEMENT.
      To the
      extent that any of the terms hereof is inconsistent with any provision of the
      Securities Purchase Agreement, the provisions of the Securities Purchase
      Agreement shall control.

     

    13.  TERMINATION;
      PARTIAL RELEASE.

     

    (a)  At
      such
      time as all the Secured Obligations in respect of the Notes have been
      indefeasibly paid and performed in full (including the conversion in full of
      the
      Notes) then the security provided for herein shall terminate, provided,
      however, that all indemnities of the Borrower and each other Grantor contained
      in this Agreement or any other Transaction Document shall survive and remain
      operative and in full force and effect regardless of the termination of this
      Agreement. 

     

    (b)  Effective
      upon the closing of a disposition of any Collateral in conformity with the
      provisions of the Securities Purchase Agreement and the Notes, and receipt
      by
      the Agent of a certification to such effect from an authorized officer of the
      Borrower, the security interest in the Collateral so disposed of shall terminate
      and the Agent shall deliver such releases as may be appropriate, provided,
      however, the security interest in all remaining Collateral shall remain in
      full
      force and effect.

     

    14.  GOVERNING
      LAW; JURISDICTION; WAIVER OF JURY TRIAL.

     

    (a)  Governing
      Law.

District
      of New York, and any appellate court from any thereof, in any action or
      proceeding arising out of or relating to this Agreement or any other Transaction
      Document, or for recognition or enforcement of any judgment, and each of the
      parties hereto irrevocably and unconditionally agrees that all claims in respect
      of any such action or proceeding may be heard and determined in such

      Grantor irrevocably and unconditionally waives, to the fullest extent permitted
      by applicable law, any objection that it may now or hereafter have to the laying
      of venue of any action or proceeding arising out of or relating to this
      Agreement or any other Transaction Document in any court referred to in

    This
      Power of Attorney is executed and delivered by ___________________, a
      ______________________ (“Grantor”),
      to
      U.S. Bank National Association as Agent for itself and Purchasers as such term
      is defined in the Securities Purchase Agreement referred to below (“Attorney”).
      This
      Power of Attorney is delivered in connection with and pursuant to a certain
      Securities Purchase Agreement dated as of even date herewith (as the same may
      be
      amended, modified, restated and/or supplemented from time to time, the

      Purchase Agreement”)
      and
      that certain Security Agreement delivered in connection therewith (the
“Security
      Agreement”).
      Capitalized terms used but not otherwise defined herein shall have the meanings
      assigned to such terms in the Security Agreement. No person to whom this Power
      of Attorney is presented, as authority for Attorney to take any action or
      actions contemplated hereby, shall be required to inquire into or seek
      confirmation from Grantor as to the authority of Attorney to take any action
      described below, or as to the existence of or fulfillment of any condition
      to
      this Power of Attorney, which is intended to grant to Attorney unconditionally
      the authority to take and perform the actions contemplated herein, and Grantor
      irrevocably waives any right to commence any suit or action, in law or equity,
      against any person or entity which acts in reliance upon or acknowledges the
      authority granted under this Power of Attorney. The power of attorney granted
      hereby is coupled with an interest, and may not be revoked or canceled by
      Grantor without Attorney’s written consent.

    

    Grantor
      hereby irrevocably constitutes and appoints Attorney (and all officers,
      employees or agents designated by Attorney), with full power of substitution,
      as
      Grantor’s true and lawful attorney-in-fact with full irrevocable power and
      authority in the place and stead of Grantor and in the name of Grantor or in
      its
      own name, from time to time in Attorney’s discretion, to take any and all
      appropriate action and to execute and deliver any and all documents and
      instruments which may be necessary or desirable to accomplish the purposes
      of
      the Securities Purchase Agreement, the Security Agreement and any and all
      agreements, documents and instruments executed, delivered or filed in connection
      therewith from time to time (collectively, the “Transaction
      Documents”)
      and,
      without limiting the generality of the foregoing, Grantor hereby grants to
      Attorney the power and right, on behalf of Grantor, without notice to or assent
      by Grantor, and at any time, to do the following:

    

    (a)  change
      the mailing address of Grantor, open a post office box on behalf of Grantor,
      open mail for Grantor, and ask, demand, collect, give acquittances and receipts
      for, take possession of, endorse any invoices, freight or express bills, bills
      of lading, storage or warehouse receipts, drafts against debtors, assignments,
      verifications, and notices in connection with any property of
      Grantor;

     

    (b)  receive,
      endorse Grantor’s name on, and collect, any checks, notes, acceptances, money
      orders, drafts and any other forms of payment or security payable to Grantor,
      and hold all amounts or proceeds so received or collected as cash collateral
      in
      a restricted account for the benefit of the Purchasers, or apply such amounts
      or
      proceeds to the Secured Obligations in accordance with the terms of the
      Securities Purchase Agreement;

     

    
      
        
        

      

      
        -1-

        
          

        

      

      
        
        

      

    

    (c)  effect
      any repairs to any asset of Grantor, or continue or obtain any insurance and
      pay
      all or any part of the premiums therefor and costs thereof, and make, settle
      and
      adjust all claims under such policies of insurance, and make all determinations
      and decisions with respect to such policies;

     

    (d)  pay
      or
      discharge any taxes, liens, security interests, or other encumbrances levied
      or
      placed on or threatened against Grantor or its property;

     

    (e)  defend
      any suit, action or proceeding brought against Grantor if Grantor does not
      defend such suit, action or proceeding or if Attorney believes that Grantor
      is
      not pursuing such defense in a manner that will maximize the recovery to
      Attorney, and settle, compromise or adjust any suit, action, or proceeding
      described above and, in connection therewith, give such discharges or releases
      as Attorney may deem appropriate;

     

    (f)  file
      or
      prosecute any claim, litigation, suit or proceeding in any court of competent
      jurisdiction or before any arbitrator, or take any other action otherwise deemed
      appropriate by Attorney for the purpose of collecting any and all such moneys
      due to Grantor whenever payable and to enforce any other right in respect of
      Grantor’s property;

     

    (g)  cause
      the
      certified public accountants then engaged by Grantor to prepare and deliver
      to
      Attorney at any time and from time to time, promptly upon Attorney’s request,
      the following reports: (i) a reconciliation of all accounts, (ii) an aging
      of
      all accounts, (iii) trial balances, (iv) test verifications of such accounts
      as
      Attorney may request, and (v) the results of each physical verification of
      inventory;

     

    (h)  communicate
      in its own name with any party to any contract with regard to the assignment
      of
      the right, title and interest of Grantor in and under the contracts and other
      matters relating thereto;

     

    (i)  to
      the
      extent that Grantor’s authorization given in the Security Agreement is not
      sufficient, to file such financing statements with respect to the Security
      Agreement as Attorney may deem appropriate and to execute in Grantor’s name such
      financing statements and amendments thereto and continuation statements which
      may require the Grantor’s signature;

     

    (j)  to
      transfer any Intellectual Property or provide licenses respecting any
      Intellectual Property; and

     

    (k)  execute,
      deliver and/or record, as applicable, in connection with any sale or other
      remedy provided for in any Transaction Document, any endorsements, assignments
      or other applications for or instruments of conveyance or transfer with respect
      to the Collateral and to otherwise direct such sale or resale, all as though
      Attorney were the absolute owner of the property of Grantor for all purposes,
      and to do, at Attorney’s option and Grantor’s expense, at any time or from time
      to time, all acts and other things that Attorney reasonably deems necessary
      to
      perfect, preserve, or realize upon Grantor’s property or assets and Attorney’s
      liens thereon, all as fully and effectively as Grantor might do. Grantor hereby
      ratifies, to the extent permitted by law, all that Attorney shall lawfully
      do or
      cause to be done by virtue hereof. Without limiting the generality of the
      foregoing, Attorney is specifically authorized to execute and file any
      applications for or instruments of transfer and assignment of any patents,
      trademarks, copyrights or other Intellectual Property with the United States
      Patent and Trademark Office and the United States Copyright Office.

    GUARANTY
      AND SURETYSHIP AGREEMENT

    

    THIS
      GUARANTY AND SURETYSHIP AGREEMENT (this “Agreement”)
      made
      as of the 25th day of May, 2006, by and among Nestor, Inc., a Delaware
      corporation (together with its successors and permitted assigns, the
“Borrower”)
      and
      the subsidiaries of the Borrower designated as “Guarantors” on the signature
      lines hereto (together with their successors and permitted assigns and any
      other
      person or entity that becomes a Guarantor hereunder pursuant to Section 5 below,
      jointly and severally, the “Guarantors”
or,
      individually, a “Guarantor”),
      in
      favor of U.S. Bank National Association, as collateral agent for the Purchasers
      (as that term is defined in the Securities Purchase Agreement referred to below)
      (together with its successors and assigns in such capacity, the “Agent”).

    

    Background

    

    The
      Agent, the Borrower and the Purchasers entered into a certain Securities
      Purchase Agreement, dated as of May 24, 2006 (as the same may be amended,
      restated, modified and/or supplemented from time to time, the “Securities
      Purchase Agreement”;
      terms
      used herein and not otherwise defined herein are used as defined in the
      Securities Purchase Agreement). Nestor Traffic Systems, Inc. is a Subsidiary
      of
      the Borrower; CrossingGuard, Inc. is a Subsidiary of Nestor Traffic Systems,
      Inc. Pursuant to the Securities Purchase Agreement, the Purchasers agreed to
      purchase the Notes from the Borrower on the terms and conditions described
      therein. The Borrower may, among other things, use the proceeds of the issuance
      of the Notes to extend credit to, and make capital contributions in, the
      Guarantors. Therefore, as a result of the Securities Purchase Agreement, the
      Guarantors can obtain capital on terms more favorable to them as part of this
      borrowing group than they could acting alone. One of the conditions to the
      extension of credit under the Securities Purchase Agreement is that the
      Guarantors guaranty payment of and act as surety for the obligations of the
      Borrower arising out of the Securities Purchase Agreement and related agreements
      and instruments.

    

    Accordingly,
      each Guarantor and the Borrower, intending to be legally bound, hereby agrees
      with the Agent as follows.

    

    NOW
      THEREFORE, in consideration of the foregoing and other good and valuable
      consideration, the receipt and sufficiency of which is hereby acknowledged,
      the
      parties hereto agree as follows:

    

    1. Guaranty
      and Suretyship.

    

    1.1 Guaranty
      of Payment.
      The
      Guarantors hereby jointly and severally agree to act as surety for the
      Guaranteed Obligations (as defined in Section 1.2 below), and irrevocably and
      unconditionally guaranty to the Agent and the Purchasers that the Guaranteed
      Obligations shall be paid in full when due and payable, whether at the stated
      or
      accelerated maturity thereof or upon any mandatory or voluntary prepayment
      or
      otherwise.

    

    
      
        
        

      

      
        -1-

        
          

        

      

      
        
        

      

    

    1.2 Definition
      of “Guaranteed Obligations”.
      For
      purposes of this Agreement, the term “Guaranteed
      Obligations”
shall
      mean (a) any obligations of the Borrower pursuant to the Securities Purchase
      Agreement and the Transaction Documents including, without limitation, any
      amounts due from time to time in respect of (i) principal and interest thereon
      under the Notes, (ii) conversion, exercise or redemption of the Notes and the
      Warrants, as applicable, (iii) fees payable under the Securities Purchase
      Agreement and (iv) indemnifications provided for, and other amounts payable,
      under the Securities Purchase Agreement or other Transaction Documents.
      Notwithstanding the definition of “Guaranteed Obligations” herein, the liability
      of each Guarantor hereunder is limited to an amount equal to (x) the amount
      that
      would render this guaranty void, voidable or unenforceable against such
      Guarantor’s creditors or creditors’ representatives under any applicable
      fraudulent conveyance, fraudulent transfer or similar act or under Section
      544
      or 548 of the Bankruptcy Code of 1978, as amended, minus (y) $1.00 (one U.S.
      Dollar).

    

    1.3 Obligations
      of Guarantors Absolute, Etc.
      The
      obligations of the Guarantors hereunder shall be absolute and unconditional.
      Each Guarantor, jointly and severally, guarantees that the Guaranteed
      Obligations will be paid strictly in accordance with the terms of the agreement,
      instrument or document giving rise to such Guaranteed Obligations, regardless
      of
      any law, regulation or order now or hereafter in effect in any jurisdiction
      affecting any such terms or the rights of the Agent and the Purchasers with
      respect thereto. The liability of the Guarantors hereunder shall be absolute
      and
      unconditional irrespective of:

    

    (a) any
      lack
      of validity or enforceability of any Transaction Document;

    

    (b) any
      change in the time, manner or place of payment of the Guaranteed
      Obligations;

    

    (c) any
      amendment or modification of or supplement to the Transaction Documents
      (including, without limitation, any amendment which would increase the amount
      of
      the Guaranteed Obligations), or any furnishing or acceptance of any security,
      or
      any release of any security or the release of any Person’s obligations
      (including without limitation, any Guarantor, the Borrower or any pledgor),
      with
      respect to the Guaranteed Obligations; 

    

    (d) any
      waiver, consent, extension, indulgence or other action or inaction under or
      in
      respect of any such instrument, document or agreement or any exercise or
      nonexercise of any right, remedy, power or privilege under or in respect of
      any
      such instrument; 

    

    (e) any
      counterclaim, setoff, recoupment or defense based upon any claim any Guarantor,
      the Borrower or any pledgor may have against the Agent or any
      Purchaser;

    

    (f) any
      bankruptcy, insolvency, reorganization, arrangement, readjustment, composition,
      liquidation or similar proceeding with respect to the Borrower, any Affiliate
      of
      the Borrower or any Guarantor or their respective properties or
      creditors;

    

    (g) any
      invalidity or unenforceability, in whole or in part, of any term hereof or
      of
      the Transaction Documents;

    

    
      
        
        

      

      
        -2-

        
          

        

      

      
        
        

      

    

    (h) any
      failure on the part of the Borrower or any Affiliate or any Person that may
      have
      been an Affiliate for any reason to perform or comply with any term of the
      Transaction Documents; or

    

    (i) any
      other
      occurrence whatsoever, whether similar or dissimilar to the
      foregoing.

    

    1.4 Continuing
      Guaranty.
      This
      guaranty and suretyship is an absolute, unconditional, present and continuing
      guaranty and suretyship of payment and is in no way conditional or contingent;
      it shall remain in full force and effect until terminated pursuant to Section
      7
      below.

    

    1.5 Joint
      and Several Liability.
      Each
      and every representation, warranty, covenant and agreement made by the
      Guarantors, or any of them, under this Agreement shall be and constitute joint
      and several obligations of all of the Guarantors, whether or not so expressly
      stated herein.

    

    1.6 Waivers.
      Each
      Guarantor hereby waives, to the fullest extent permitted by applicable law,
      (a)
      all presentments, demands for performance, notice of non-performance, protests,
      notices of protests and notices of dishonor in connection with the Guaranteed
      Obligations or any agreement relating thereto; (b) notice of acceptance of
      this
      Agreement; (c) any requirement of diligence or promptness on the part of the
      Agent or any Purchaser in the enforcement of its rights hereunder or under
      the
      Transaction Documents; (d) any enforcement of any present or future agreement
      or
      instrument relating directly or indirectly to the Guaranteed Obligations; (e)
      notice of any of the matters referred to in subsection 1.3 hereof; (f) notices
      of every kind and description which may be required to be given by any statute
      or rule of law; and (g) any defense of any kind which it may now or hereafter
      have with respect to its liability under this Agreement to the fullest extent
      permitted by law. Without limiting the foregoing, the Agent and the Purchasers
      shall not be required to make any demand upon, or to pursue or exhaust any
      rights or remedies against the Borrower, any other Guarantor or any other
      Person, or against the collateral security, for the Guaranteed Obligations.
      No
      failure on the part of the Agent or the Purchasers to exercise, and no delay
      in
      exercising, any right hereunder shall operate as a waiver thereof; nor shall
      any
      single or partial exercise of any right hereunder preclude any other or further
      exercise thereof or the exercise of any other right. The remedies herein
      provided are cumulative and not exclusive of any remedies provided by law.
      Each
      Guarantor hereby agrees that it will not enforce or otherwise exercise or claim
      or assert any rights of subrogation or contribution against any Person with
      respect to the Guaranteed Obligations or any security therefor unless and until
      all the Guaranteed Obligations are paid in full. EACH
      GUARANTOR’S WAIVERS UNDER THIS SECTION 1.6 HAVE BEEN MADE VOLUNTARILY,
      INTELLIGENTLY AND KNOWINGLY AND AFTER SUCH GUARANTOR HAS BEEN APPRISED AND
      COUNSELED BY ITS ATTORNEY AS TO THE NATURE THEREOF AND ITS POSSIBLE ALTERNATIVE
      RIGHTS.

    

    2. Expenses.

    

    Whether
      or not the transactions contemplated by this Agreement are fully consummated,
      each Guarantor and the Borrower shall promptly pay (or reimburse, as the Agent
      may elect) all costs and expenses which the Agent has incurred or may incur
      in
      connection with the negotiation, preparation, reproduction, interpretation,
      administration and enforcement of this Agreement and all amendments, waivers,
      modifications and supplements hereto and the collection of all amounts due
      hereunder, including, without limitation, reasonable fees of counsel to the
      Agent.

    

    
      
        
        

      

      
        -3-

        
          

        

      

      
        
        

      

    

    3. Representations
      and Warranties.

    

    The
      Guarantors hereby jointly and severally represent and warrant that each of
      the
      representations and warranties relating to them set forth in any Transaction
      Document is incorporated herein by reference and is true and correct on and
      as
      of the date hereof.

    

    4. Covenants.

    

    Each
      of
      the covenants and agreements of the Borrower which are set forth or incorporated
      in any of the Transaction Documents and which are expressly applicable or refer
      to the “Subsidiaries” of Borrower or otherwise refer to any Guarantors are
      hereby incorporated by reference as though set forth herein in their entirety,
      and each Guarantor hereby agrees to perform and abide by each such covenant
      and
      agreement which purports to be applicable to it.

    

    5. Additional
      Parties.

    

    Except
      as
      otherwise provided in the Transaction Documents, the Guarantors shall at all
      times constitute all of the direct and indirect Subsidiaries of Borrower (other
      than Nestor Interactive, Inc. (“NII”),
      but
      only so long as NII is inactive and has no significant assets other than net
      operating losses). If any Person becomes such a Subsidiary after the date hereof
      or, in the case of NII, if it ceases to be inactive or has significant assets
      other than net operating losses, such Person shall become a Guarantor hereunder,
      and the Borrower shall cause such Person to signify its acceptance of the terms
      hereof by execution and delivery to the Agent of one or more counterparts of
      the
      Joinder hereto, appropriately dated.

    

    6. Right
      of Set-off.

    

    Each
      Guarantor hereby pledges and gives to each Purchaser a lien and security
      interest for the amount of the Guaranteed Obligations upon and in the balance
      of
      any account maintained by such Guarantor with such Purchaser or any other
      liability of such Purchaser to such Guarantor. Upon the occurrence of and
      throughout the period in which the Purchasers reasonably believe there is
      continuing an Event of Default under the Notes, each Guarantor hereby authorizes
      each Purchaser to apply any such deposit balances now or hereafter in the
      possession of such Purchaser to the payment of the Guaranteed Obligations.
      The
      provisions hereof shall not be deemed or construed to limit rights of set-off
      or
      liens or similar rights which any Purchaser may otherwise have by reason of
      applicable Law or other agreement.

    

    
      
        
        

      

      
        -4-

        
          

        

      

      
        
        

      

    

    7. Termination
      of Guaranty.

    

    7.1 Termination
      of Guaranty Obligations of All Guarantors.
      At such
      time as (a) no Purchaser has any Commitment to make further fundings to the
      Borrower under the terms of the Securities Purchase Agreement and (b) all the
      Guaranteed Obligations in respect of the Notes have been indefeasibly paid
      and/or performed in full (including the conversion in full of the Notes), then
      the guaranty provided for herein and this Agreement shall terminate,
provided,
      however,
      that
      (i) all indemnities of the Guarantors or the Borrower contained in this
      Agreement or any Transaction Document shall survive and remain operative and
      in
      full force and effect regardless of the termination of this Agreement, and
      (ii)
      the guaranty provided for herein shall be reinstated if at any time any payment
      of any of the Guaranteed Obligations is rescinded or must otherwise be returned
      by the Agent or any Purchaser upon the insolvency, bankruptcy or reorganization
      of the Borrower or any Guarantor or otherwise, all as though such payment had
      not been made.

    

    7.2 Termination
      of Guaranty Obligations of Sold Guarantors.
      Effective upon the closing of a sale or other disposition by the Borrower or
      any
      Subsidiary of the Borrower of all the outstanding capital stock of, or all
      partnership interests or all other equity interests in, any of the Guarantors
      hereunder (any Guarantor being so sold is hereinafter the “Sold
      Guarantor”)
      in
      conformity with the provisions of the Securities Purchase Agreement and the
      Notes, and receipt by the Agent of a certification to such effect from the
      chief
      financial officer of the Borrower, the obligations of that Sold Guarantor
      hereunder (including, without limitation, obligations under Section 9 below)
      shall terminate. However, all the obligations of the other Guarantors hereunder
      shall remain in full force and effect.

    

    8. Miscellaneous.

    

    8.1 Governing
      Law.
      This
      Agreement shall be governed by and construed in accordance with the laws of
      the
      State of New York (without giving effect to the choice of law provisions
      thereof).

    

    8.2 Specific
      Performance.
      The
      Borrower and each Guarantor hereby authorizes the Agent and the Purchasers
      to
      demand specific performance of this Agreement at any time when the Borrower
      or
      such Guarantor shall have failed to comply with any provision hereof, and the
      Borrower and each Guarantor hereby irrevocably waives any defense based on
      the
      adequacy of a remedy at law which might be asserted as a bar to the remedy
      of
      specific performance hereof in any action brought therefor.

    

    8.3 Acknowledgement
      of Terms of Securities Purchase Agreement and the Notes; Relationship to
      Securities Purchase Agreement and the Notes.
      Each
      Guarantor hereby acknowledges receipt from the Borrower of a correct and
      complete copy of the Securities Purchase Agreement and the Notes and consents
      to
      all of the provisions of the Securities Purchase Agreement and the Notes as
      in
      effect on the date of this Agreement and agrees that
      its consent is not required for any amendments, modifications, restatements
      or
      waivers of the Securities Purchase Agreement or the Notes or any of the
      provisions thereof.
      If any
      of the terms hereof are inconsistent with those of the Securities Purchase
      Agreement or the Notes (including, without limitation, any amendments,
      restatements, supplements and waivers that the Guarantors have been made aware
      of), those of the Securities Purchase Agreement or the Notes, as applicable,
      shall control.

    8.4 Non-Exclusive
      Remedies. No
      remedy
      or right herein conferred upon, or reserved to the Agent or the Purchasers
      is
      intended to be to the exclusion of any other remedy or right, but each and
      every
      such remedy or right shall be cumulative and shall be in addition to every
      other
      remedy or right given hereunder or under any other contract or under
      law.

    

    8.5 Delay
      and Non-Waiver.
      No
      delay or omission by the Agent or any Purchaser to exercise any remedy or right
      hereunder shall impair any such remedy or right or shall be construed to be
      a
      waiver of any Event of Default, or an acquiescence therein, nor shall it affect
      any subsequent Event of Default of the same or of a different
      nature.

    

    8.6 Successors
      and Assigns.
      Except
      as
      otherwise provided in the Securities Purchase Agreement, the Agent may assign
      or
      transfer this Agreement and any or all rights or obligations hereunder without
      the consent of the Borrower or any Guarantor and without prior notice. Neither
      the Borrower nor any Guarantor shall assign or transfer this Agreement or any
      rights or obligations hereunder without the prior written consent of the Agent.
      The rights and privileges of the Agent and the Purchasers under this Agreement
      shall inure to the benefit of their respective successors, assigns and
      participants. All promises, covenants and agreements of the Borrower and each
      Guarantor contained in this Agreement shall be binding upon personal
      representatives, heirs, successors and assigns of such Person.
      Notwithstanding the foregoing, if there shall become additional “Guarantors” or
      if there should be any assignment of any guaranty obligations by operation
      of
      law or in contravention of the terms of this Agreement or otherwise, then all
      covenants, agreements, representations and warranties made herein or pursuant
      hereto by or on behalf of the Guarantors shall bind the successors and assigns
      of the Guarantors and any such additional Guarantors, jointly and severally,
      together with the preexisting Guarantors whether or not such new or additional
      Guarantors execute the Joinder as set forth in Section 5.

    

    8.7 Amendments
      and Waivers.
      This
      Agreement represents the entire agreement between the parties with respect
      to
      the transactions contemplated herein and, except as expressly provided herein,
      shall not be affected by reference to any other documents. The Purchasers
      holding 75% of the total outstanding principal balance of the Notes (the
“Required
      Holders”)
      shall
      have the right to direct the Agent, from time to time, to consent to any
      amendment, modification or supplement to or waiver of any provision of this
      Agreement and to release any Collateral from any lien or security interest
      held
      by the Agent; provided,
      however,
      that
      (i) no such direction shall require the Agent to consent to the modification
      of
      any provision or portion thereof which (in the sole judgment of the Agent)
      is
      intended to benefit the Agent, (ii) the Agent shall have the right to decline
      to
      follow any such direction if the Agent shall determine in good faith that the
      directed action is not permitted by the terms of this Agreement or may not
      lawfully be taken and (iii) no such direction shall waive or modify any
      provision of this Agreement the waiver or modification of which requires the
      consent of all Purchasers unless all Purchasers consent thereto. The Agent
      may
      rely on any such direction given to it by the Required Holders and shall be
      fully protected in relying thereon, and shall under no circumstances be liable,
      except in circumstances involving the Agent's gross negligence or willful
      misconduct as shall have been determined in a final nonappealable judgment
      of a
      court of competent jurisdiction, to any holder of the Notes or any other person
      or entity for taking or refraining from taking action in accordance with any
      direction or otherwise in accordance with this Agreement.

    8.8 Notices
      and Communications.
      Any
      notice contemplated herein or required or permitted to be given hereunder shall
      be made in the manner set forth in the Securities Purchase Agreement and
      delivered at the addresses set forth on the signature pages to this Agreement,
      or to such other address as any party hereto may have last specified by written
      notice to the other party or parties.

    

    8.9 Headings;
      Counterparts. Headings
      to this Agreement are for purposes of reference only and shall not limit or
      otherwise affect the meaning hereof. This Agreement may be executed in any
      number of counterparts, each of which shall be an original, and all of which,
      taken together, shall constitute one instrument. Delivery
      of a photocopy or telecopy of an executed counterpart of a signature page to
      this Agreement shall be as effective as delivery of a manually executed
      counterpart of such signature page.

    

    8.10 Severability.
      If
      any of
      the provisions or terms of this Agreement shall for any reason be held to be
      invalid or unenforceable such invalidity or unenforceability shall not affect
      any of the other terms hereof, but this Agreement shall be construed as if
      such
      invalid or unenforceable term had never been contained herein. Any such
      invalidity or unenforceability in a particular jurisdiction shall not be deemed
      to render a provision invalid or unenforceable in any other jurisdiction.
Without
      limiting the generality of the foregoing, any invalidity, illegality or
      unenforceability of any term or provision of this Agreement in any jurisdiction
      or as against any Guarantor shall not affect the validity, legality or
      enforceability of any other terms hereof or in any other jurisdiction or against
      any other Guarantor.

    

    9. Indemnification.

    

    Each
      Guarantor, jointly and severally, shall indemnify, reimburse and hold harmless
      all Indemnitees from and against any and all losses, claims, liabilities,
      damages, penalties, suits, costs and expenses, of any kind or nature, (including
      fees relating to the cost of investigating and defending any of the foregoing)
      imposed on, incurred by or asserted against such Indemnitee in any way related
      to or arising from or alleged to arise from this Agreement or the guarantees
      provided herein except any such losses, claims, liabilities, damages, penalties,
      suits, costs and expenses which result from the gross negligence or willful
      misconduct of the Indemnitee as determined by a final nonappealable decision
      of
      a court of competent jurisdiction. This indemnification provision is in addition
      to, and not in limitation of, any other indemnification provision in any other
      Transaction Document.

    10. Jurisdiction;
      Waiver of Jury Trial.

    

    For
      the
      purpose of any action that may be brought in connection with this Agreement,
      the
      Borrower and each Guarantor hereby consents to the jurisdiction and venue of
      the
      courts of the State of New York or of any federal court located in such state
      and waives personal service of any and all process upon it and consents that
      all
      such service of process be made by certified or registered mail directed to
      the
      Borrower or Guarantor at the address provided for in Section 8.8. Service so
      made shall be deemed to be completed upon actual receipt at the address
      specified in said section. The Borrower and each Guarantor waives the right
      to
      contest the jurisdiction and venue of the courts located in the county of New
      York, State of New York on the ground of inconvenience or otherwise and,
      further, waives any right to bring any action or proceeding against (a) the
      Agent in any court outside the county of New York, State of New York, or (b)
      any
      other Purchaser other than in a state within the United States designated by
      such Purchaser. The provisions of this Section shall not limit or otherwise
      affect the right of the Agent or any Purchaser to institute and conduct an
      action in any other appropriate manner, jurisdiction or court.

    

    NO
      PARTY
      TO THIS AGREEMENT, NOR ANY ASSIGNEE, SUCCESSOR, HEIR OR PERSONAL REPRESENTATIVE
      OF THE FOREGOING SHALL SEEK A JURY TRIAL IN ANY PROCEEDING BASED UPON OR ARISING
      OUT OF THIS AGREEMENT OR ANY OTHER TRANSACTION DOCUMENT RELATING TO SUCH
      INDEBTEDNESS OR THE RELATIONSHIP BETWEEN OR AMONG SUCH PERSONS OR ANY OF THEM.
      NO SUCH PERSON WILL SEEK TO CONSOLIDATE ANY SUCH ACTION WITH ANY OTHER ACTION
      IN
      WHICH A JURY TRIAL CANNOT BE OR HAS NOT BEEN WAIVED.

    

    EXCEPT
      AS PROHIBITED BY LAW, EACH PARTY HERETO WAIVES ANY RIGHTS IT MAY HAVE TO CLAIM
      OR RECOVER IN ANY LITIGATION REFERRED TO IN THIS SECTION, ANY SPECIAL,
      EXEMPLARY, PUNITIVE OR CONSEQUENTIAL DAMAGES.
      EACH
      PARTY TO THIS AGREEMENT (i) CERTIFIES THAT NEITHER THE AGENT NOR ANY
      REPRESENTATIVE, OR ATTORNEY OF THE AGENT NOR ANY PURCHASER HAS REPRESENTED,
      EXPRESSLY OR OTHERWISE, THAT THE AGENT OR SUCH PURCHASER WOULD NOT, IN THE
      EVENT
      OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVERS AND (ii) ACKNOWLEDGES
      THAT
      IT HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT AND EACH OTHER TRANSACTION
      DOCUMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS HEREIN.
      THE PROVISIONS OF THIS SECTION HAVE BEEN FULLY DISCLOSED TO THE PARTIES AND
      THE
      PROVISIONS SHALL BE SUBJECT TO NO EXCEPTIONS. NO PARTY HAS IN ANY WAY AGREED
      WITH OR REPRESENTED TO ANY OTHER PARTY THAT THE PROVISIONS OF THIS SECTION
      WILL
      NOT BE FULLY ENFORCED IN ALL INSTANCES.
