    AGREEMENTS
      OF DEBTOR

     

    From
      and
      after the date of this Security Agreement, and until all of the Obligations
      are
      paid in full, Debtor shall:

      Not
      sell, lease, transfer or otherwise dispose of Collateral or any interest
      therein, except as provided for in the Securities Purchase Agreement and for

    (a)  At
      the
      expense of Debtor, defend the Security Interest against any and all claims
      of
      any Person adverse to Vicis (but only to the extent the claim of such adverse
      Person is subordinate or junior to the interest of Vicis) and take such action
      and execute such financing statements and other documents as Vicis may from
      time
      to time reasonably request in writing to maintain the perfected status of the
      Security Interest. Debtor shall not further encumber or grant a security
      interest in any of the Collateral except as provided for in the Securities
      Purchase Agreement.

     

    
      
         

      

      
        4

        
          

        

      

      
         

      

    

     

    (b)  Debtor
      further agrees to take any other commercially reasonable action reasonably
      requested in writing by Vicis to ensure the attachment, perfection and second
      priority of, and the ability of Vicis to enforce its security interest in any
      and all of the Collateral including, without limitation, (i) executing,
      delivering and, where appropriate, filing financing statements and amendments
      relating thereto under the UCC, to the extent, if any, that Debtor’s signature
      thereon is required therefor, (ii) complying with any provision of any statute,
      regulation or treaty of the United States as to any Collateral if compliance
      with such provision is a condition to attachment, perfection or priority of,
      or
      ability of Vicis to enforce, its security interest in such Collateral, (iii)
      taking all actions required by any earlier versions of the UCC (to the extent
      applicable) or by other law, as applicable in any relevant UCC jurisdiction,
      or
      by other law as applicable in any foreign jurisdiction, and (iv) obtaining
      waivers from landlords where any material portion of the tangible Collateral
      is
      located in form and substance reasonably satisfactory to Vicis.

     

    3.3  Locations.
      Give
      Vicis at least thirty (30) days prior written notice of Debtor’s intention to
      relocate the tangible Collateral (other than Inventory in transit) or any of
      the
      records relating to the Collateral from the locations listed on Schedule
      1
      attached
      to this Security Agreement, in which event Schedule
      1
      shall be
      deemed amended to include the new location. Any additional filings or refilings
      requested in writing by Vicis as a result of any such relocation in order to
      maintain the Security Interest in such Collateral shall be at Debtor’s
      expense.

     

    3.4  Insurance.
      Maintain
      insurance (including, without limitation, commercial general liability and
      property insurance) with respect to the Collateral consisting of tangible
      personal property in such amounts, against such risks, in such form and with
      responsible and reputable insurance companies or associations as is required
      by
      any governmental authority having jurisdiction with respect thereto or as is
      carried generally in accordance with sound business practice by companies in
      similar businesses similarly situated. Debtor will obtain lender’s loss payable
      endorsements on applicable insurance policies in favor of Vicis and will provide
      to Vicis certificates of such insurance or copies thereof. Debtor shall use
      commercially reasonable efforts to cause each insurer to agree, by endorsement
      on the policy or policies or certificates of insurance issued by it or by
      independent instrument furnished to Vicis, that such insurer will give thirty
      (30) days written notice to Vicis before such policy will be altered or
      canceled. No settlement of any insurance claim shall be made without Vicis’s
      prior consent, which consent will not be unreasonably withheld, conditioned
      or
      delayed. In the event of any insured loss, Debtor shall promptly notify Vicis
      thereof in writing, and, after an Event of Default shall have occurred and
      be
      continuing, Debtor hereby authorizes and directs any insurer concerned to make
      payment of such loss directly to Vicis as its interest may appear. Vicis is
      authorized, in the name and on behalf of Debtor, to make proof of loss and
      to
      adjust, compromise and collect, in such manner and amounts as it reasonably
      shall determine, all claims under all policies; and Debtor agrees to sign,
      on
      written demand of Vicis, all receipts, vouchers, releases and other instruments
      which may be necessary in aid of this authorization. After an Event of Default
      shall have occurred and be continuing, the proceeds of any insurance from loss,
      theft, or damage to the Collateral shall be held in a segregated account
      established by Vicis and disbursed and applied at the discretion of Vicis,
      either in reduction of the Obligations or applied toward the repair, restoration
      or replacement of the Collateral.

     

    
      
         

      

      
        5

        
          

        

      

      
         

      

    

     

    3.5  Name;
      Legal Status.
      (a)
      Without providing at least 30 days prior written notice to Vicis, Debtor will
      not change its name, its place of business or, if more than one, chief executive
      office, or its mailing address or organizational identification number if it
      has
      one, (b) if Debtor does not have an organizational identification number and
      later obtains one, Debtor shall forthwith notify Vicis of such organizational
      identification number, and (c) Debtor will not change its type of organization
      or jurisdiction of organization.

      to Cure.
      In
      case
      of failure by Debtor after receipt of written notice from Vicis to procure
      or
      maintain insurance, or to pay any fees, assessments, charges or taxes (subject
      to Debtor’s right to contest in good faith, such assessments, charges or taxes)
      arising with respect to the Collateral, Vicis shall have the right, but shall
      not be obligated, to effect such insurance or pay such fees, assessments,
      charges or taxes, as the case may be, and, in that event, the cost thereof
      shall
      be payable by Debtor to Vicis immediately upon demand, together with interest
      at
      an annual rate of 8% from the date of disbursement by Vicis to the date of
      payment by Debtor. If Vicis effects any insurance on behalf of Debtor, Debtor
      thereafter may cancel such insurance so effected after providing Vicis with
      evidence that Debtor has obtained insurance as required by this Security
      Agreement.

      no obligation so to do):

      records pertaining to all Collateral that are necessary to properly administer
      and control the Collateral or the handling and collection of Collateral, and
      sell, lease or otherwise dispose of the Collateral in a commercially reasonable
      manner in whole or in part, at public or private sale, on or off the premises
      of
      Debtor; and

     

    (c)  collect
      any and all money due or to become due and enforce in Debtor’s name all rights
      with respect to the Collateral; and

     

    (d)  settle,
      adjust or compromise any dispute with respect to any Account; and

     

    (e)  receive
      and open mail addressed to Debtor; and

     

    
      
         

      

      
        6

      evidences of payment.

     

    4.3  Power
      of Attorney.
      Upon
      the occurrence and during the continuance of an Event of Default, Debtor does
      hereby constitute and appoint Vicis as Debtor’s true and lawful attorney with
      full power of substitution for Debtor in Debtor’s name, place and stead for the
      purposes of performing any obligation of Debtor under this Security Agreement
      and taking any action and executing any instrument which Vicis may deem
      necessary or advisable to perform any obligation of Debtor under this Security
      Agreement, which appointment is irrevocable and coupled with an interest, and
      shall not terminate until the Obligations are paid in full.

     

    4.4  Right
      to Collect Accounts.
      Upon
      the occurrence and during the continuance of an Event of Default, and without
      limiting Debtor’s obligations under the Transaction Documents: (a) Debtor
      authorizes Vicis to notify any and all debtors on the Accounts to make payment
      directly to Vicis (or to such place as Vicis may direct); (b) Debtor agrees,
      on
      written notice from Vicis, to deliver to Vicis promptly after receipt thereof,
      in the form in which received (together with all necessary endorsements), all
      payments received by Debtor on account of any Account; and (c) Vicis may, at
      its
      option, apply all such payments against the Obligations or remit all or part
      of
      such payments to Debtor.

     

    4.5  Reasonable
      Notice.  Written
      notice, when required by law, sent in accordance with the provisions of Section
      12.6 of the Securities Purchase Agreement and given at least ten (10) calendar
      days (counting the day of sending) before the date of a proposed disposition
      of
      the Collateral shall be reasonable notice.

     

    4.6  Limitation
      on Duties Regarding Collateral.  The
      sole duty of Vicis with respect to the custody, safekeeping and physical
      preservation of the Collateral in its possession, under Section 9-207 of the
      UCC
      or otherwise, shall be to deal with it in the same manner as Vicis deals with
      similar property for its own account. Neither Vicis nor any of its directors,
      officers, employees or agents, shall be liable for failure to demand, collect
      or
      realize upon any of the Collateral or for any delay in doing so or shall be
      under any obligation to sell or otherwise dispose of any Collateral upon the
      request of Debtor or otherwise.

     

    4.7  Lock
      Box; Collateral Account.
      This
      Section 4.7 shall be effective only upon the occurrence and during the
      continuance of an Event of Default. If Vicis so requests in writing, Debtor
      will
      direct each of its debtors on the Accounts to make payments due under the
      relevant Account or chattel paper directly to a special lock box to be under
      the
      control of Vicis. Debtor hereby authorizes and directs Vicis to deposit into
      a
      special collateral account to be established and maintained by Vicis all checks,
      drafts and cash payments received in said lock box. All deposits in said
      collateral account shall constitute proceeds of Collateral and shall not
      constitute payment of any Obligation until so applied. At its option, Vicis
      may,
      at any time, apply finally collected funds on deposit in said collateral account
      to the payment of the Obligations, in the order of application set forth in
      Section
      4.8,
      or
      permit Debtor to withdraw all or any part of the balance on deposit in said
      collateral account. If a collateral account is so established, Debtor agrees
      that it will promptly deliver to Vicis, for deposit into said collateral
      account, all payments on Accounts and chattel paper received by it. All such
      payments shall be delivered to Vicis in the form received (except for Debtor’s
      endorsement where necessary). Until so deposited, all payments on Accounts
      and
      chattel paper received by Debtor shall be held in trust by Debtor for and as
      the
      property of Vicis and shall not be commingled with any funds or property of
      Debtor.

    4.8  Application
      of Proceeds.
      Vicis
      shall apply the proceeds resulting from any sale or disposition of the
      Collateral in the following order:

     

    (a)  to
      the
      reasonable costs of any sale or other disposition;

     

    (b)  to
      the
      reasonable expenses incurred by Vicis in connection with any sale or other
      disposition, including attorneys’ fees;

     

    (c)  to
      the
      payment of the Obligations then due and owing in any order selected by Vicis
      in
      a commercially reasonable manner; and

     

    (d)  to
      Debtor.

     

    4.9  Other
      Remedies.  No
      remedy herein conferred upon Vicis is intended to be exclusive of any other
      remedy, and each and every such remedy shall be cumulative and shall be in
      addition to every other remedy given under this Security Agreement and the
      Transaction Documents now or hereafter existing at law or in equity or by
      statute or otherwise. No failure or delay on the part of Vicis in exercising
      any
      right or remedy hereunder shall operate as a waiver thereof nor shall any single
      or partial exercise of any right hereunder preclude other or further exercise
      thereof or the exercise of any other right or remedy.
