      in
      and to the following, whether now owned or existing or owned, acquired, or

    3. Security
      for Secured Obligations.
      The
      security interest created hereby in the Pledged Collateral of each Pledgor

      existing or hereafter incurred (the “Secured
      Obligations”):

      all
      of the Obligations, howsoever evidenced, created, incurred or acquired, whether
      primary, secondary, direct, contingent, or joint and several; (b) the

      the Pledged Collateral of such Pledgor and (ii) promptly upon the receipt
      thereof by or on behalf of a Pledgor, all other certificates and instruments

      If such
      Pledgor shall receive by virtue of its being or having been the owner of any
      Pledged Collateral, any (i) certificate, including without limitation, any

    (c) Financing
      Statements.
      Each
      Pledgor authorizes the Bank to prepare and file such UCC or other applicable
      financing statements as may be reasonably deemed necessary or desirable by the
      Bank in order to perfect and protect the security interest created hereby in
      the
      Pledged Collateral of such Pledgor.

    

    (d) Provisions
      Relating to Securities Entitlements and Securities Accounts.
      With
      respect to any Pledged Collateral consisting of a Securities Entitlement or
      held
      in a Securities Account, (a) the applicable Pledgor and the applicable
      Securities Intermediary shall enter into an agreement with the Bank granting
      Control to the Bank over such Pledged Collateral, such agreement to be in form
      and substance reasonably satisfactory to the Bank and (b) the Bank shall be
      entitled, upon the occurrence and during the continuance of a Default or an
      Event of Default, to notify the applicable Securities Intermediary that it
      should follow the Entitlement Orders of the Bank and no longer follow the
      Entitlement Orders of the applicable Pledgor. Upon receipt by a Pledgor of
      notice from a Securities Intermediary of its intent to terminate the Securities
      Account of such Pledgor held by such Securities Intermediary, prior to the
      termination of such Securities Account the Pledged Collateral in such Securities
      Account shall be (i) transferred to a new Securities Account which is subject
      to
      a control agreement as provided above or (ii) transferred to an account held
      by
      the Bank (in which it will be held until a new Securities Account is
      established).

    

    5. Representations
      and Warranties.
      Each
      Pledgor hereby represents and warrants to the Bank, for the benefit of the
      Bank,
      that until all of the Secured Obligations have been satisfied in full:

    

    (a) Authorization
      of Pledged Collateral.
      The
      Pledged Collateral is duly authorized and validly issued, is fully paid and
      nonassessable and is not subject to the preemptive rights of any Person. All
      other shares of capital stock constituting Pledged Collateral will be duly
      authorized and validly issued, fully paid and nonassessable and not subject
      to
      the preemptive rights of any Person.

    

    (b) Title.
      Each
      Pledgor has good and indefeasible title to the Pledged Collateral of such
      Pledgor and will at all times be the legal and beneficial owner of such Pledged
      Collateral free and clear of any Lien, other than Permitted Liens. There exists
      no Adverse Claim with respect to the Pledged Collateral of such
      Pledgor.

    

    (c) Exercising
      of Rights.
      The
      exercise by the Bank of its rights and remedies hereunder will not violate
      any
      law or governmental regulation or any material contractual restriction binding
      on or affecting a Pledgor or any of its property, provided that the Bank obtains
      all necessary Governmental Approvals pursuant to Section
      10(e)
      hereof.

     

    
      
        
        

      

      
        4

        
          

        

      

      
        
        

      

    

     

    (d) Pledgor’s
      Authority.
      No
      authorization, approval or action by, and no notice or filing with any
      Governmental Authority, the issuer of any Pledged Collateral or third party
      is
      required either (i) for the pledge made by a Pledgor or for the granting of
      the
      security interest by a Pledgor pursuant to this Pledge Agreement or (ii) for
      the
      exercise by the Bank of its rights and remedies hereunder (except as may be
      required by laws affecting the offering and sale of securities).

    

    (e) Security
      Interest/Priority.
      This
      Pledge Agreement creates a valid security interest in favor of the Bank for
      the
      benefit of the Bank in the Pledged Collateral. The taking possession by the
      Bank
      of the certificates (if any) representing the Pledged Collateral and all other
      certificates and instruments constituting Pledged Collateral will perfect and
      establish the first priority (subject to Permitted Liens) of the Bank’s security
      interest in all certificated Pledged Collateral and such certificates and
      instruments. Each Pledgor is a "registered organization", as that term is
      defined in Article 9 of the UCC, and its name on its signature line hereto
      is
      its exact legal name as registered in the state of its organization. Upon the
      filing of UCC financing statements in the appropriate filing office in the
      location of each Pledgor’s State
      of
      organization,
      the
      Bank shall have a perfected first priority (subject to Permitted Liens) security
      interest in all uncertificated Pledged Collateral consisting of partnership
      or
      limited liability company interests that do not constitute a Security pursuant
      to Section 8-103(c) of the UCC. With respect to any Pledged Collateral
      consisting of a Securities Entitlement or held in a Securities Account, upon
      execution and delivery by the applicable Pledgor, the applicable Securities
      Intermediary and the Bank of an agreement granting Control to the Bank over
      such
      Pledged Collateral, the Bank shall have a perfected first priority (subject
      to
      Permitted Liens) security interest in such Pledged Collateral. Except as set
      forth in this Section, no action is necessary to perfect or otherwise protect
      such security interest.

    

    (f) No
      Other Capital Securities.
      Except
      as set forth on Exhibit
      A
      attached
      hereto, as revised or updated from time to time after the date hereof by the
      Pledgor, no Pledgor owns any Capital Securities of any Person. Exhibit
      A,
      hereto,
      as revised or updated from time to time after the date hereof by the Pledgor,
      as
      it pertains to each Pledgor, includes all Foreign Subsidiaries directly owned
      by
      such Pledgor, and does not include any Person not directly owned by such
      Pledgor. The Pledgor shall send to the Bank such revised or updated Exhibit
      A’s
      from
      time to time as is necessary to reflect the current ownership of the Capital
      Securities of the Pledgor in Subsidiaries..

    

    (g) Partnership
      and Limited Liability Company Interests.
      Except
      as previously disclosed in writing to the Bank, none of the Pledged Collateral
      consisting of partnership or limited liability company interests (i) is dealt
      in
      or traded on a securities exchange or in a securities market, (ii) by its terms
      expressly provides that it is a security governed by Article 8 of the UCC,
      (iii)
      is an investment company security, (iv) is held in a securities account or
      (v)
      constitutes a Security or a Financial Asset.

    6. Covenants.
      Each
      Pledgor hereby covenants that until all of the Credit and Collateral Termination
      Events have occurred, such Pledgor shall:

    

    (a) Defense
      of Title.
      Use
      commercially reasonable efforts to warrant and defend title to and ownership
      of
      the Pledged Collateral of such Pledgor at its own expense against the claims
      and
      demands of all other parties claiming an interest therein, keep the Pledged
      Collateral free from all Liens, except for Permitted Liens, and not sell,
      exchange, transfer, assign, lease or otherwise dispose of Pledged Collateral
      of
      such Pledgor or any interest therein, except as permitted under the Loan
      Agreement and the other Loan Documents.

    

    (b) Further
      Assurances.
      Promptly execute and deliver at its expense all further instruments and
      documents and take all further action that may be necessary or reasonably
      desirable or that the Bank may reasonably request in order to (i) perfect and
      protect the security interest created hereby in the Pledged Collateral of such
      Pledgor (including, without limitation, the authentication and filing of UCC
      financing statements and any and all action reasonably necessary to satisfy
      the
      Bank that the Bank has obtained a first priority perfected security interest
      in
      all Pledged Collateral); (ii) enable the Bank to exercise and enforce its rights
      and remedies hereunder in respect of the Pledged Collateral of such Pledgor;
      and
      (iii) otherwise effect the purposes of this Pledge Agreement, including, without
      limitation and if requested by the Bank, delivering to the Bank irrevocable
      proxies in respect of the Pledged Collateral of such Pledgor.

    

    (c) Amendments.
      Not
      make or consent to any amendment or other modification or waiver with respect
      to
      any of the Pledged Collateral of such Pledgor or enter into any agreement or
      allow to exist any restriction with respect to any of the Pledged Collateral
      of
      such Pledgor other than pursuant hereto or as may be permitted under the Loan
      Agreement.

    

    (d) Compliance
      with Securities Laws.
      File
      all reports and other information now or hereafter required to be filed by
      such
      Pledgor with the United States Securities and Exchange Commission and any other
      state, federal or foreign agency in connection with the ownership of the Pledged
      Collateral of such Pledgor.

    

    (e) Issuance
      or Acquisition of Captial Securities.
      Not
      without executing and delivering, or causing to be executed and delivered,
      to
      the Bank such agreements, documents and instruments as the Bank may reasonably
      require, issue or acquire any capital stock consisting of an interest in a
      partnership or a limited liability company that (i) is dealt in or traded on
      a
      securities exchange or in a securities market, (ii) by its terms expressly
      provides that it is a security governed by Article 8 of the UCC, (iii) is an
      investment company security, (iv) is held in a Securities Account or (v)
      constitutes a Security or a Financial Asset.

    7. Performance
      of Obligations; Advances by Bank.
      Upon
      the occurrence and during the continuance of an Event of Default, on failure
      of
      any Pledgor to perform any of the covenants and agreements contained herein,
      the
      Bank may, at its sole option and in its reasonable discretion, perform or cause
      to be performed the same and in so doing may expend such sums as the Bank may
      reasonably deem advisable in the performance thereof, including, without
      limitation, the payment of any insurance premiums, the payment of any taxes,
      a
      payment to obtain a release of a Lien or potential Lien, expenditures made
      in
      defending against any adverse claim and all other expenditures which the Bank
      may make for the protection of the security hereof or which may be compelled
      to
      make by operation of law. All such sums and amounts so expended shall be
      repayable by the Pledgor on a joint and several basis promptly upon timely
      notice thereof and demand therefor, shall constitute additional Secured
      Obligations and shall bear interest from the date said amounts are expended
      at
      the Default Rate. No such performance of any covenant or agreement by the Bank
      on behalf of any Pledgor, and no such advance or expenditure therefor, shall
      relieve the Pledgor of any default under the terms of this Pledge Agreement,
      the
      other Loan Documents or any Hedging Agreement between any Obligor and the Bank
      or affiliate of the Bank. The Bank may make any payment hereby authorized in
      accordance with any bill, statement or estimate procured from the appropriate
      public office or holder of the claim to be discharged without inquiry into
      the
      accuracy of such bill, statement or estimate or into the validity of any tax
      assessment, sale, forfeiture, tax lien, title or claim except to the extent
      such
      payment is being contested in good faith by a Pledgor in appropriate proceedings
      and against which adequate reserves are being maintained in accordance with
      GAAP. 

    

    8. Events
      of Default.
      The
      occurrence of an event which under the Loan Agreement would constitute an Event
      of Default shall be an event of default hereunder (an “Event
      of Default”).

    

    9. Remedies.
      

    

    (a) General
      Remedies.
      Upon
      the occurrence of an Event of Default and during the continuation thereof,
      the
      Bank shall have, in respect of the Pledged Collateral of any Pledgor, in
      addition to the rights and remedies provided herein, in the Loan Documents,
      in
      any Hedging Agreement between any Obligor and the Bank or by law, the rights
      and
      remedies of a secured party under the UCC or any other applicable law.

    (b) Sale
      of Pledged Collateral.
      Upon
      the occurrence of an Event of Default and during the continuation thereof,
      without limiting the generality of this Section and without notice, the Bank
      may, in its reasonable discretion, sell or otherwise dispose of or realize
      upon
      the Pledged Collateral, or any part thereof, in one or more parcels, at public
      or private sale, at any exchange or broker’s board or elsewhere, at such price
      or prices and on such other terms as the Bank may deem commercially reasonable,
      for cash, credit or for future delivery or otherwise in accordance with
      applicable law. To the extent permitted by law, the Bank may in such event,
      bid
      for the purchase of such securities. Each Pledgor agrees that, to the extent
      notice of sale shall be required by law and has not been waived by such Pledgor,
      any requirement of reasonable notice shall be met if notice, specifying the
      place of any public sale or the time after which any private sale is to be
      made,
      is personally served on or mailed, postage prepaid, to such Pledgor, in
      accordance with the notice provisions of the Loan Agreement at least 10 days
      before the time of such sale. The Bank shall not be obligated to make any sale
      of Pledged Collateral of such Pledgor regardless of notice of sale having been
      given. The Bank may adjourn any public or private sale from time to time by
      announcement at the time and place fixed therefor, and such sale may, without
      further notice, be made at the time and place to which it was so
      adjourned.

    

    (c) Private
      Sale.
      Upon
      the occurrence of an Event of Default and during the continuation thereof,
      the
      Pledgor recognizes that the Bank may deem it impracticable to effect a public
      sale of all or any part of the Pledged Collateral and that the Bank may,
      therefore, determine to make one or more private sales of any such Pledged
      Collateral to a restricted group of purchasers that have agreed, among other
      things, to acquire such Pledged Collateral for their own account, for investment
      and not with a view to the distribution or resale thereof. Each Pledgor
      acknowledges that any such private sale may be at prices and on terms less
      favorable to the seller than the prices and other terms which might have been
      obtained at a public sale and, notwithstanding the foregoing, agrees that such
      private sale shall be deemed to have been made in a commercially reasonable
      manner and that the Bank shall have no obligation to delay sale of any such
      Pledged Collateral for the period of time necessary to permit the issuer of
      such
      Pledged Collateral to register such Pledged Collateral for public sale under
      the
      Securities Act of 1933. Each Pledgor further acknowledges and agrees that any
      offer to sell such Pledged Collateral which has been (i) publicly advertised
      on
      a bona fide basis in a newspaper or other publication of general circulation
      in
      the financial community of New York, New York (to the extent that such offer
      may
      be advertised without prior registration under the Securities Act of 1933),
      or
      (ii) made privately in the manner described above shall be deemed to involve
      a
“public sale” under the UCC, notwithstanding that such sale may not constitute a
“public offering” under the Securities Act of 1933, and the Bank may, in such
      event, bid for the purchase of such Pledged Collateral.

    

    (d) Retention
      of Pledged Collateral.
      In
      addition to the rights and remedies hereunder, upon the occurrence of an Event
      of Default and during the continuation thereof, the Bank may, after providing
      the notices required by Section 9-621 of the UCC (or any successor sections
      of
      the UCC) or otherwise complying with the requirements of applicable law of
      the
      relevant jurisdiction, accept or retain all or any portion of the Pledged
      Collateral in full or partial satisfaction of the Secured Obligations. Unless
      and until the Bank shall have provided such notices, however, the Bank shall
      not
      be deemed to have retained any Pledged Collateral in satisfaction of any Secured
      Obligations for any reason.

     

    
      
        
        

      

      
        8

        
          

        

      

      
        
        

      

    

     

    (e) Deficiency.
      In the
      event that the proceeds of any sale, collection or realization are insufficient
      to pay all amounts to which the Bank is legally entitled, the Pledgor shall
      be
      jointly and severally liable for the deficiency, together with interest thereon
      at the Default Rate, together with the costs of collection and the reasonable
      fees of any attorneys employed by the Bank to collect such deficiency. Any
      surplus remaining after the full payment and satisfaction of the Secured
      Obligations shall be returned to the Pledgor or to whomsoever a court of
      competent jurisdiction shall determine to be entitled thereto. 

    

    (f) Other
      Security.
      To the
      extent that any of the Secured Obligations are now or hereafter secured by
      property other than the Pledged Collateral (including, without limitation,
      real
      and other personal property owned by a Pledgor), or by a guarantee, endorsement
      or property of any other Person, then the Bank shall have the right to proceed
      against such other property, guarantee or endorsement upon the occurrence of
      any
      Event of Default, and the Bank has the right, in its sole discretion, to
      determine which rights, security, liens, security interests or remedies the
      Bank
      shall at any time pursue, relinquish, subordinate, modify or take with respect
      thereto, without in any way modifying or affecting any of them or any of the
      Bank’s rights or the Secured Obligations under this Pledge Agreement, under any
      other of the Loan Documents or under any Hedging Agreement between any Obligor
      and the Bank or an affiliate of the Bank.

    

    10. Rights
      of the Bank.

    

    (a) Power
      of Attorney.
      In
      addition to other powers of attorney contained herein, each Pledgor hereby
      designates and appoints the Bank and each of its designees or agents as
      attorney-in-fact of such Pledgor, irrevocably and with power of substitution,
      with authority to take any or all of the following actions upon the occurrence
      and during the continuation of an Event of Default:

    

    (i) to
      demand, collect, settle, compromise, adjust and give discharges and releases
      concerning the Pledged Collateral of such Pledgor, all as the Bank may
      reasonably determine;

    

    (ii) to
      commence and prosecute any actions at any court for the purposes of collecting
      any of the Pledged Collateral of such Pledgor and enforcing any other right
      in
      respect thereof;

    

    (iii) to
      defend, settle, adjust or compromise any action, suit or proceeding brought
      and,
      in connection therewith, give such discharge or release as the Bank may deem
      reasonably appropriate;

     

    
      
        
        

      

      
        9

        
          

        

      

      
        
        

      

    

     

    (iv) to
      pay or
      discharge taxes, liens, security interests, or other encumbrances levied or
      placed on or threatened against the Pledged Collateral of such
      Pledgor;

    

    (v) to
      direct
      any parties liable for any payment under any of the Pledged Collateral to make
      payment of any and all monies due and to become due thereunder directly to
      the
      Bank or as the Bank shall direct;

    

    (vi) to
      receive payment of and receipt for any and all monies, claims, and other amounts
      due and to become due at any time in respect of or arising out of any Pledged
      Collateral of such Pledgor;

    

    (vii) to
      sign
      and endorse any drafts, assignments, proxies, stock powers, verifications,
      notices and other documents relating to the Pledged Collateral of such
      Pledgor;

    

    (viii) to
      execute and deliver all assignments, conveyances, statements, financing
      statements, renewal financing statements, pledge agreements, affidavits, notices
      and other agreements, instruments and documents that the Bank may determine
      necessary in order to perfect and maintain the security interests and liens
      granted in this Pledge Agreement and in order to fully consummate all of the
      transactions contemplated herein;

    

    (ix) to
      exchange any of the Pledged Collateral of such Pledgor or other property upon
      any merger, consolidation, reorganization, recapitalization or other
      readjustment of the issuer thereof and, in connection therewith, deposit any
      of
      the Pledged Collateral of such Pledgor with any committee, depository, transfer
      agent, registrar or other designated agency upon such terms as the Bank may
      determine;

    

    (x) to
      vote
      for a shareholder, partner or member resolution, or to sign an instrument in
      writing, sanctioning the transfer of any or all of the Pledged Collateral of
      such Pledgor into the name of the Bank or into the name of any transferee to
      whom the Pledged Collateral of such Pledgor or any part thereof may be sold
      pursuant to Section
      9
      hereof;
      and

    

    (xi) to
      do and
      perform all such other acts and things as the Bank may reasonably deem to be
      necessary, proper or convenient in connection with the Pledged Collateral of
      such Pledgor.

    

    
      	 	
              This
                power of attorney is a power coupled with an interest and shall be
                irrevocable until all of the Secured Obligations have been satisfied
                in
                full. The Bank shall be under no duty to exercise or withhold the
                exercise
                of any of the rights, powers, privileges and options expressly or
                implicitly granted to the Bank in this Pledge Agreement, and shall
                not be
                liable for any failure to do so or any delay in doing so. The Bank
                shall
                not be liable for any act or omission or for any error of judgment
                or any
                mistake of fact or law in its individual capacity or its capacity
                as
                attorney-in-fact except acts or omissions resulting from its gross
                negligence or willful misconduct. This power of attorney is conferred
                on
                the Bank solely to protect, preserve and realize upon its security
                interest in the Pledged Collateral.

    (b) Assignment
      by the Bank.
      The
      Bank may from time to time assign the Secured Obligations or any portion thereof
      and/or its Lien on the Pledged Collateral or any portion thereof, and the
      assignee shall be entitled to all of the rights and remedies of the Bank under
      this Pledge Agreement in relation thereto.

    

    (c) The
      Bank’s Duty of Care.
      Other
      than the exercise of reasonable care to ensure the safe custody of the Pledged
      Collateral while being held by the Bank hereunder, the Bank shall have no duty
      or liability to preserve rights pertaining thereto, it being understood and
      agreed that Pledgor shall be responsible for preservation of all rights in
      the
      Pledged Collateral of such Pledgor, and the Bank shall be relieved of all
      responsibility for Pledged Collateral upon surrendering it or tendering the
      surrender of it to the Pledgor. The Bank shall be deemed to have exercised
      reasonable care in the custody and preservation of the Pledged Collateral in
      its
      possession if such Pledged Collateral is accorded treatment substantially equal
      to that which the Bank accords its own property, which shall be no less than
      the
      treatment employed by a reasonable and prudent agent in the industry, it being
      understood that the Bank shall not have responsibility for (i) ascertaining
      or
      taking action with respect to calls, conversions, exchanges, maturities, tenders
      or other matters relating to any Pledged Collateral, whether or not the Bank
      has
      or is deemed to have knowledge of such matters; or (ii) taking any necessary
      steps to preserve rights against any parties with respect to any Pledged
      Collateral.

    

    (d) Voting
      Rights in Respect of the Pledged Collateral.

    

    (i) Until
      such time as an Event of Default shall have occurred and be continuing and
      the
      Bank shall have given Borrower notice thereof, to the extent permitted by law,
      each Pledgor may exercise any and all voting and other consensual rights
      pertaining to the Pledged Collateral of such Pledgor or any part thereof for
      any
      purpose not inconsistent with the terms of this Pledge Agreement or the Loan
      Agreement; and

    

    (ii) Subject
      to Subsection
      (e)
      of this
      Section, upon the occurrence and during the continuance of an Event of Default
      and notice from Bank to Borrower, all rights of a Pledgor to exercise the voting
      and other consensual rights which it would otherwise be entitled to exercise
      pursuant to paragraph (i) of this Subsection
      (d)
      shall
      cease and all such rights shall thereupon become vested in the Bank which shall
      then have the sole right to exercise such voting and other consensual
      rights.

     

    
      
        
        

      

      
        11

        
          

        

      

      
        
        

      

    

     

    (e) Dividend
      and Distribution Rights in Respect of the Pledged Collateral.

    

    (i) So
      long
      as no Event of Default shall have occurred and be continuing and subject to
      Section
      4(b)
      hereof,
      each Pledgor may receive and retain any and all dividends (other than stock
      or
      ownership interest dividends and other dividends constituting Pledged Collateral
      which are addressed hereinabove), distributions or interest paid in respect
      of
      the Pledged Collateral to the extent they are allowed under the Loan
      Agreement.

    

    (ii) Upon
      the
      occurrence and during the continuation of an Event of Default:

    

    (A) all
      rights of a Pledgor to receive the dividends, distributions and interest
      payments which it would otherwise be authorized to receive and retain pursuant
      to paragraph (i) of this Subsection
      (e)
      shall
      cease and all such rights shall thereupon be vested in the Bank which shall
      then
      have the sole right to receive and hold as Pledged Collateral such dividends,
      distributions and interest payments; and

    

    (B) all
      dividends, distributions and interest payments which are received by a Pledgor
      contrary to the provisions of clause (A) of this paragraph (ii) shall be
      received in trust for the benefit of the Bank, shall be segregated from other
      property or funds of such Pledgor, and shall be forthwith paid over to the
      Bank
      as Pledged Collateral in the exact form received, to be held by the Bank as
      Pledged Collateral and as further collateral security for the Secured
      Obligations.

    

    (f) Release
      of Pledged Collateral.
      The
      Bank may release any of the Pledged Collateral from this Pledge Agreement or
      may
      substitute any of the Pledged Collateral for other Pledged Collateral without
      altering, varying or diminishing in any way the force, effect, lien, pledge
      or
      security interest of this Pledge Agreement as to any Pledged Collateral not
      expressly released or substituted, and this Pledge Agreement shall continue
      as a
      first priority lien on all Pledged Collateral not expressly released or
      substituted.

    

    11. Application
      of Proceeds.
      Upon
      the occurrence and during the continuation of an Event of Default, any payments
      in respect of the Secured Obligations and any proceeds of any Pledged
      Collateral, when received by the Bank in cash or its equivalent, will be applied
      in reduction of the Secured Obligations in the order set forth in the Loan
      Agreement, and each Pledgor irrevocably waives the right to direct the
      application of such payments and proceeds and acknowledges and agrees that
      the
      Bank shall have the continuing and exclusive right to apply and reapply any
      and
      all such payments and proceeds in the Bank’s sole discretion, notwithstanding
      any entry to the contrary upon any of its books and records.

    12. Costs
      of Counsel.
      If
      at any
      time hereafter, whether upon the occurrence of an Event of Default or not,
      the
      Bank employs counsel to prepare or consider amendments, waivers or consents
      with
      respect to this Pledge Agreement, or to take action or make a response in or
      with respect to any legal or arbitral proceeding relating to this Pledge
      Agreement or relating to the Pledged Collateral, or to protect the Pledged
      Collateral or exercise any rights or remedies under this Pledge Agreement or
      with respect to the Pledged Collateral, then the Pledgor agrees to promptly
      pay
      in accordance with the Loan Agreement any and all such reasonable documented
      costs and expenses of the Bank, all of which costs and expenses shall constitute
      Secured Obligations hereunder.

    

    13. Continuing
      Agreement.

    

    (a) This
      Pledge Agreement shall be a continuing agreement in every respect and shall
      remain in full force and effect until all of the Secured Obligations have been
      satisfied in full. Upon the occurrence of all of the Secured Obligations being
      satisfied in full, this Pledge Agreement shall be automatically terminated
      and
      the Bank shall, upon the request and at the expense of the Pledgor, forthwith
      release all of its liens and security interests hereunder and shall execute
      and
      deliver all UCC termination statements and/or other documents reasonably
      requested by the Pledgor evidencing such termination. Notwithstanding the
      foregoing all releases and indemnities provided hereunder shall survive
      termination of this Pledge Agreement.

    

    (b) This
      Pledge Agreement shall continue to be effective or be automatically reinstated,
      as the case may be, if at any time payment, in whole or in part, of any of
      the
      Secured Obligations is rescinded or must otherwise be restored or returned
      by
      the Bank as a preference, fraudulent conveyance or otherwise under any
      bankruptcy, insolvency or similar law, all as though such payment had not been
      made; provided that in the event payment of all or any part of the Secured
      Obligations is rescinded or must be restored or returned, all reasonable costs
      and expenses (including without limitation any reasonable legal fees and
      disbursements) incurred by the Bank in defending and enforcing such
      reinstatement shall be deemed to be included as a part of the Secured
      Obligations.

    

    14. Amendments;
      Waivers; Modifications.
      This
      Pledge Agreement and the provisions hereof may not be amended, waived, modified,
      changed, discharged or terminated except as set forth in the Loan Agreement.
      

    

    15. Successors
      in Interest.
      This
      Pledge Agreement shall create a continuing security interest in the Pledged
      Collateral and shall be binding upon each Pledgor, its successors and assigns
      and shall inure, together with the rights and remedies of the Bank hereunder,
      to
      the benefit of the Bank and its successors and permitted assigns; provided,
      however,
      that
      the Pledgor may not assign its rights or delegate its duties hereunder without
      the prior written consent of the Bank, as required by the Loan Agreement.

    16. Notices.
      All
      notices required or permitted to be given under this Pledge Agreement shall
      be
      in conformance with the Loan Agreement or the Guaranty, as
      applicable.

    

    17. Counterparts.
      This
      Pledge Agreement may be executed in any number of counterparts, each of which
      where so executed and delivered shall be an original, but all of which shall
      constitute one and the same instrument. It shall not be necessary in making
      proof of this Pledge Agreement to produce or account for more than one such
      counterpart.

    

    18. Headings.
      The
      headings of the sections and subsections hereof are provided for convenience
      only and shall not in any way affect the meaning, construction or interpretation
      of any provision of this Pledge Agreement.

      WITH COUNSEL, EACH KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVE IRREVOCABLY,
      ANY RIGHT TO A TRIAL BY JURY IN ANY ACTION OR PROCEEDING TO ENFORCE OR DEFEND
      ANY RIGHTS UNDER THIS PLEDGE AGREEMENT, ANY NOTE, ANY OTHER LOAN DOCUMENT,

      CONNECTION WITH ANY OF THE FOREGOING, OR ANY COURSE OF CONDUCT OR COURSE OF
      DEALING IN WHICH THE BANK AND ANY PLEDGOR ARE ADVERSE PARTIES, AND EACH AGREES
      THAT ANY SUCH ACTION OR PROCEEDING SHALL BE TRIED BEFORE A COURT AND NOT BEFORE

      unenforceable, such provision shall be fully severable and the remaining
      provisions shall remain in full force and effect and shall be construed without
      giving effect to the illegal, invalid or unenforceable provisions.

    

    23. Entirety.
      This
      Pledge Agreement, the other Loan Documents and any Hedging Agreement between
      any
      Obligor and the Bank or any affiliate of the Bank represent the entire agreement
      of the parties hereto and thereto, and supersede all prior agreements and
      understandings, oral or written, if any, including any commitment letters or
      correspondence relating to this Pledge Agreement, the other Loan Documents,
      any
      such Hedging Agreement or the transactions contemplated herein and
      therein.

    

    24. Survival.
      All
      representations and warranties of the Pledgor hereunder shall survive the
      execution and delivery of this Pledge Agreement, the other Loan Documents and
      any Hedging Agreement between any Obligor and the Bank or any affiliate of
      the
      Bank, the delivery of the Notes and the making of the Loans and the issuance
      of
      the Letters of Credit under the Loan Agreement.

     

    25. Marshalling.
      The
      Bank shall not be under any obligation to marshall any assets in favor of any
      Pledgor or any other Person or against or in payment of any or all of the
      Secured Obligations. 

    

    26. Subordination
      and Postponement of Subrogation Rights.
      Each
      Pledgor hereby subordinates any right of subrogation, indemnity, reimbursement
      or contribution against the issuer of any Pledged Collateral or any other
      Obligor arising on account of any disposition of or other realization on the
      Pledged Collateral by the Bank pursuant to Section 9 to the rights and interests
      of the Bank in the Pledged Collateral and agrees that it shall not attempt
      to
      exercise or realize on any such rights until
      all
      of the Secured Obligations have been satisfied in full.

    27. Conflicts.
      To the
      extent that any provision of this Pledge Agreement is inconsistent with or
      conflicts with any provision of the Loan Agreement, the provision of the Loan
      Agreement will control.

    

    28. Amendment.
      This
      Pledge Agreement amends and restates the Original Pledge in its
      entirety.

    

    Each
      of
      the parties hereto has caused a counterpart of this Pledge Agreement to be
      duly
      executed and delivered as of the date first above written.

      (“Bank”).

     

    RECITALS

    

    A. On
      October 21, 2004, Guarantor executed and delivered to Bank a Continuing
      Unconditional Guaranty (“Original
      Guaranty”)
      pertaining to the Bank’s loans and financial accommodations to ISI Detention
      Contracting, Inc., a Delaware corporation (n/k/a ISI Security Group,
      Inc.).

     

    B.
       ISI
      Security Group, Inc., a Delaware corporation (“Borrower”)
      and
      Bank have entered into that certain Amended and Restated Loan and Security
      Agreement of even date herewith (the “Loan
      Agreement”),
      pursuant to which the Bank has agreed to make a revolving loan and a term loan
      in the original aggregate amount of SIXTEEN MILLION TWO HUNDRED AND FIFTY
      THOUSAND AND NO/100 DOLLARS ($16,250,000.00) (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
      Guarantor unconditionally guarantees payment and performance to Bank of the
      Obligations; and

     

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

     

    AGREEMENT

    

    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, Guarantor agrees with Bank, as
      follows:

     

    
      
        
        

      

      
        
        

        
          

        

      

      
        
        

      

    

     

    Section
      1. Guaranty
      of Obligations. 

    

    Guarantor
      hereby absolutely, irrevocably and unconditionally guarantees to Bank the
      payment and performance of the Obligations as and when the same shall be due
      and
      payable, whether by lapse of time, by acceleration of maturity or otherwise.
      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 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. Guarantor agrees that, as between
      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 Guarantor for the
      purposes of this Guaranty.

    

    Section
      2. Guaranty
      Absolute.
      Guarantor guarantees that the Obligations shall be paid strictly in accordance
      with the terms of the Loan Documents. The liability of Guarantor 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.
      Guarantor shall not exercise any rights which it 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 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 Guarantor makes 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 Guarantor's request, execute and deliver
      to
      Guarantor appropriate documents, without recourse and without representation
      or
      warranty, necessary to evidence the transfer by subrogation to Guarantor 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 Guarantor in connection with any extension of credit or financial
      accommodation by 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 Guarantor, if Bank so requests,
      shall be collected, enforced and received by 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 Guarantor under the other
      provisions of this Guaranty.

    

    Section
      7. Representations
      and Warranties.
      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 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 Guarantor
      enforceable against Guarantor 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, Guarantor has (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).

    

    Section
      8. Financial
      Reports and Covenants.

    (b)  Bank
      and
      its accountants shall have the right to examine the records, books, management
      and other papers of Guarantor which reflect upon its financial condition, at
      the
      Collateral or at any office regularly maintained by Guarantor where the books
      and records are located. Bank and its accountants shall have the right to make
      copies and extracts from the foregoing records and other papers. In addition,
      Bank and its accountants shall have the right to examine and audit the books
      and
      records of 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.

     

    Section
      9. Remedies
      Generally.
      The
      remedies provided in this Guaranty are cumulative and not exclusive of any
      remedies provided by law.

    

    Section
      10. Setoff.
      If
      a
      Default shall have occurred and be continuing, Bank is hereby authorized at
      any
      time and from time to time, to the fullest extent permitted by law, and to
      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 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.
      Guarantor waives presentment, demand, notice of dishonor, protest, notice of
      acceptance of this Guaranty or incurrence of any of the Obligations and any
      other formality with respect to any of the Obligations or this
      Guaranty.

    

    Section
      12. Amendments
      and Waivers.
      No
      amendment or waiver of any provision of this Guaranty, nor consent to any
      departure by Guarantor therefrom, shall be effective unless it is in writing
      and
      signed by Bank, and then the waiver or consent shall be effective only in the
      specific instance and for the specific purpose for which given. No failure
      on
      the part of Bank to exercise, and no delay in exercising, any right under this
      Guaranty shall operate as a waiver or preclude any other or further exercise
      thereof or the exercise of any other right.

    Section
      17. 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) 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 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. 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 Guarantor or its properties in the courts of any
      jurisdiction.

    (c) 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.
      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) 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.

      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
      shall remain in full force and effect and shall not be affected by the illegal,
      invalid or unenforceable provision or by its severance from this Guaranty,
      unless such continued effectiveness of this Guaranty, as modified, would be
      contrary to the basic understandings and intentions of the parties as expressed
      herein.

      DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS GUARANTY OR THE

      AGENT OR ATTORNEY OF THE OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE,
      THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE
