    A. ISI
      Security Group, Inc., a Delaware corporation (“Borrower”)
      and
      Bank have entered into that certain Loan and Security Agreement of even date
      herewith (the “Loan
      Agreement”),
      pursuant to which the Bank has agreed to make two (2) revolving loans and a
      term
      loan in the original aggregate amount of twenty-five million and no/100 dollars
      ($25,000,000.00) (the “Loans”).
      All
      capitalized terms used herein but not defined herein shall have the meanings
      ascribed to them in the Loan Agreement.

     

    B. The
      Bank
      is not willing to make the Loans, or otherwise extend credit, to Borrower unless
      the Guarantors unconditionally guaranty payment and performance to Bank of
      the
      Obligations; and

     

    C. Each
      Guarantor is a subsidiary or affiliate of the Borrower, and the Guarantors
      will
      directly benefit from the Bank making the Loans to Borrower.

     

    NOW
      THEREFORE, as an inducement to the Bank to make the Loans to Borrower, and
      for
      other good and valuable consideration, the receipt and legal sufficiency of
      which are hereby acknowledged, each Guarantor agrees with Bank, as
      follows:

     

    A
      G R
      E E M E N T:

    


    Section
      1. GUARANTY
      OF OBLIGATIONS.

     

    Each
      Guarantor hereby absolutely, irrevocably and unconditionally guarantees to
      Bank
      the payment and performance of the obligations, as defined in the Loan Agreement
      (the “Obligations”),
      as
      and when the same shall be due and payable, whether by lapse of time, by
      acceleration of maturity or otherwise. Each Guarantor hereby absolutely,
      irrevocably and unconditionally covenants and agrees that it is liable, jointly
      and severally, for the Obligations as a primary obligor, and that each Guarantor
      shall fully perform each and every term and provision hereof. This Guaranty
      is a
      guaranty of payment and not of collection only. Bank shall not be required
      to
      exhaust any right or remedy or take any action against Borrower or any other
      person or entity or any collateral. Each Guarantor agrees that, as between
      each
      Guarantor and Bank, the Obligations may be declared to be due and payable for
      the purposes of this Guaranty notwithstanding any stay, injunction or other
      prohibition which may prevent, delay or vitiate any declaration as regards
      Borrower and that in the event of a declaration or attempted declaration, the
      Obligations shall immediately become due and payable by Guarantors for the
      purposes of this Guaranty.


    
      
        
        

      

      
        
        

        
          

        

      

      
        
        

      

    

     

    Section
      2. GUARANTY
      ABSOLUTE.

     

    Each
      Guarantor guarantees that the Obligations shall be paid strictly in accordance
      with the terms of the Loan Documents. The liability of the Guarantors under
      this
      Guaranty is absolute and unconditional irrespective of: (a) any change in
      the time, manner or place of payment of, or in any other term of, all or any
      of
      the Obligations, or any other amendment or waiver of or any consent to departure
      from any of the terms of any Loan Document, including any increase or decrease
      in the rate of interest thereon; (b) any release or amendment or waiver of,
      or consent to departure from, or failure to act by Bank with respect to, any
      other guaranty or support document, or any exchange, release or non-perfection
      of, or failure to act by Bank with respect to, any Collateral, for all or any
      of
      the Obligations; (c) any present or future law, regulation or order of any
      jurisdiction (whether of right or in fact) or of any agency thereof purporting
      to reduce, amend, restructure or otherwise affect any term of the Obligations
      or
      any Loan Document; (d) any change in the corporate existence, structure, or
      ownership of Borrower; (e) without being limited by the foregoing, any lack
      of validity or enforceability of any Loan Document; and (f) any other
      setoff, recoupment, defense or counterclaim whatsoever (in any case, whether
      based on contract, tort or any other theory) with respect to the Loan Documents
      or the transactions contemplated thereby which might constitute a legal or
      equitable defense available to, or discharge of, Borrower or a
      Guarantor.

     

    Section
      3. GUARANTY
      IRREVOCABLE.

     

    This
      Guaranty is a continuing guaranty of the payment of all Obligations now or
      hereafter existing and shall remain in full force and effect until payment
      in
      full of all Obligations and other amounts payable under this Guaranty and until
      the Loan Documents are no longer in effect.

     

    Section
      4. REINSTATEMENT.

     

    This
      Guaranty shall continue to be effective or be reinstated, as the case may be,
      if
      at any time any payment of any of the Obligations is rescinded or must otherwise
      be returned by the Bank on the insolvency, bankruptcy or reorganization of
      Borrower or otherwise, all as though the payment had not been made, whether
      or
      not Bank is in possession of the Guaranty.

     

    Section
      5. SUBROGATION.

     

    Guarantors
      shall not exercise any rights which they may acquire by way of subrogation,
      by
      any payment made under this Guaranty or otherwise, until all the Obligations
      have been paid in full and the Loan Documents are no longer in effect. If any
      amount is paid to any Guarantor on account of subrogation rights under this
      Guaranty at any time when all the Obligations have not been paid in full, the
      amount shall be held in trust for the benefit of the Bank and shall be promptly
      paid to Bank to be credited and applied to the Obligations, whether matured
      or
      unmatured or absolute or contingent, in accordance with the terms of the Loan
      Documents. If Guarantors make payment to Bank of all or any part of the
      Obligations and all the Obligations are paid in full and the Loan Documents
      are
      no longer in effect, Bank shall, at any Guarantor's request, execute and deliver
      to Guarantors appropriate documents, without recourse and without representation
      or warranty, necessary to evidence the transfer by subrogation to Guarantors
      of
      the interest in the Obligations resulting from the payment.

    Section
      6. SUBORDINATION.

     

    Without
      limiting Bank’s rights under any other agreement, any liabilities owed by
      Borrower to any Guarantor in connection with any extension of credit or
      financial accommodation by any Guarantor to or for the account of Borrower,
      including but not limited to interest accruing at the agreed contract rate
      after
      the commencement of a bankruptcy or similar proceeding, are hereby subordinated
      to the Obligations, and such liabilities of Borrower to Guarantors, if Bank
      so
      requests, shall be collected, enforced and received by a Guarantor as trustee
      for the Bank and shall be paid over to Bank on account of the Obligations but
      without reducing or affecting in any manner the liability of Guarantors under
      the other provisions of this Guaranty.

     

    Section
      7. REPRESENTATIONS
      AND WARRANTIES.

     

    Each
      Guarantor represents and warrants that: (a) this Guaranty (i) has been
      authorized by all necessary action; (ii) does not violate any agreement,
      instrument, law, regulation or order applicable to any Guarantor;
      (iii) does not require the consent or approval of any person or entity,
      including but not limited to any governmental authority, or any filing or
      registration of any kind; and (iv) is the legal, valid and binding
      obligation of Guarantors enforceable against Guarantors, jointly and severally,
      in accordance with its terms, except to the extent that enforcement may be
      limited by applicable bankruptcy, insolvency and other similar laws affecting
      creditors' rights generally; and (b) in executing and delivering this
      Guaranty, Guarantors have (i) without reliance on Bank or any information
      received from Bank and based upon such documents and information it deems
      appropriate, made an independent investigation of the transactions contemplated
      hereby and Borrower, Borrower’s business, assets, operations, prospects and
      condition, financial or otherwise, and any circumstances which may bear upon
      such transactions, Borrower or the obligations and risks undertaken herein
      with
      respect to the Obligations; (ii) adequate means to obtain from Borrower on
      a continuing basis information concerning Borrower; (iii) full and complete
      access to the Loan Documents and any other documents executed in connection
      with
      the Loan Documents; and (iv) not relied and will not rely upon any
      representations or warranties of Bank not embodied herein or any acts heretofore
      or hereafter taken by Bank (including but not limited to any review by Bank
      of
      the affairs of Borrower).

      and other papers of each Guarantor which reflect upon its financial condition,
      at the Collateral or at any office regularly maintained by each Guarantor where

      books and records of each Guarantor pertaining to the income, expenses and
      operation of the Collateral during reasonable business hours at any office
      of
      Guarantor where the books and records are located.

      any

      the
      extent permitted under the Loan Agreement, to set off and apply any and all
      deposits (general or special, time or demand, provisional or final) at any
      time
      held and other obligations at any time owing by Borrower to or for the credit
      or
      the account of any Guarantor against any of and all the Obligations held by
      Bank, irrespective of whether or Bank shall have made any demand under this
      Guaranty and although such Obligations may be unmatured. The rights of Bank
      under this Section are in addition to other rights and remedies (including
      other
      rights of setoff) which Bank may have.

     

    Section
      11. FORMALITIES.

      and
      performance of the Obligations, including all defenses based upon suretyship
      or

    Section
      18. GOVERNING
      LAW; JURISDICTION; CONSENT TO SERVICE OF PROCESS.

     

    (a) This
      Guaranty shall be construed in accordance with and governed by the law of the
      State of Illinois.

     

    (b) Each
      Guarantor hereby irrevocably and unconditionally submits, for itself and its
      property, to the nonexclusive jurisdiction of any United States Federal or
      Illinois State court sitting in Chicago, Illinois, and any appellate court
      from
      any thereof, in any action or proceeding arising out of or relating to this
      Guaranty, or for recognition or enforcement of any judgment, and each Guarantor
      hereby irrevocably and unconditionally agrees that all claims in respect of
      any
      such action or proceeding may be heard and determined in such Illinois State
      or,
      to the extent permitted by law, in such Federal court. Each Guarantor hereto
      agrees that a final judgment in any such action or proceeding shall be
      conclusive and may be enforced in other jurisdictions by suit on the judgment
      or
      in any other manner provided by law. Nothing in this Guaranty shall affect
      any
      right that Bank may otherwise have to bring any action or proceeding relating
      to
      this Guaranty against any Guarantor or its properties in the courts of any
      jurisdiction.

     

    (c) Each
      Guarantor hereby irrevocably and unconditionally waives, to the fullest extent
      it may legally and effectively do so, any objection which it may now or
      hereafter have to the laying of venue of any suit, action or proceeding arising
      out of or relating to this Guaranty in any court referred to in subsection (b)
      above.
      Each Guarantor hereby irrevocably waives, to the fullest extent permitted by
      law, the defense of an inconvenient forum to the maintenance of such action
      or
      proceeding in any such court.

     

    (d) Each
      Guarantor irrevocably consents to service of process in the manner provided
      for
      notices in Section 16
      hereof.
      Nothing in this Guaranty will affect the right of Bank to serve process in
      any
      other manner permitted by law.

     

    Section
      19. INVALID
      PROVISIONS.

     

    If
      any
      provision of this Guaranty is held to be illegal, invalid, or unenforceable
      under present or future laws effective during the term of this Guaranty, such
      provision shall be fully severable and this Guaranty shall be construed and
      enforced as if such illegal, invalid or unenforceable provision had never
      comprised a part of this Guaranty, and the remaining provisions of this Guaranty
