    REPRESENTATIONS
      AND COVENANTS

    

    The
      Debtors further represent, warrant, covenant, and agree with the Bank as
      follows: 

    

    3.1 Ownership
      of Collateral; Security Interest Priority.  At
      the time any Collateral becomes subject to a security interest of the Bank
      hereunder, unless the Bank shall otherwise consent, the Debtors shall be deemed
      to have represented and warranted that (a) a Debtor is the lawful owner of
      such
      Collateral or has the power to transfer the Collateral and have the right and
      authority to subject the same to the security interest of the Bank; and (b)
      other than Permitted Liens, none of the Collateral is subject to any Lien other
      than that in favor of the Bank and there is no effective financing statement
      or
      other filing covering any of the Collateral on file in any public office, other
      than in favor of the Bank. Upon filing of financing statements in the
      appropriate jurisdictions, this Agreement creates in favor of the Bank a valid
      first-priority perfected security interest, subject only to Permitted Liens,
      in
      the Collateral in which a security interest may be perfected by the filing
      of a
      financing statement, enforceable against each Debtor and all third parties
      and
      securing the payment of the Secured Liabilities. The Debtors authorize the
      Bank
      to file financing statements describing the Collateral as determined by the
      Bank
      and if requested will execute and deliver to the Bank all documents and take
      such other actions as may from time to time be requested by the Bank in order
      to
      maintain a first perfected security interest in, and if applicable, possession
      and control of, the Collateral. The Debtors further ratify and consent to the
      filing of any financing statement by the Bank which may have been filed prior
      to
      the date hereof. The Debtors will keep the Collateral free at all times from
      any
      and all Liens other than Permitted Liens. The Debtors will not, without the
      prior written consent of the Bank, sell, lease, license, transfer, assign or
      otherwise dispose, or permit or suffer to be sold, leased, licensed,
      transferred, assigned or otherwise disposed, any of the Collateral, except
      for,
      prior to an Event of Default only (notwithstanding any other agreement), any
      assets permitted to be sold, leased, licensed, transferred, assigned or
      otherwise disposed under the Loan Agreement. The Bank or its attorneys may
      at
      any and all reasonable times inspect the Collateral and for such purpose upon
      reasonable notice to the Debtors may enter upon any and all premises where
      the
      Collateral is or might be kept or located, subject to any limitations, if any,
      in the Loan Agreement.

    3.2 Names;
      Locations.
      Each
      Debtor represents and warrants that Schedule 2 sets forth the following for
      each
      Debtor: (a) the jurisdiction in which each Debtor is located for purposes of
      Sections 9-301 and 9-307 of the UCC; (b) the address of each Debtor's chief
      executive office; (c) each location a secured party would have filed a UCC
      financing statement to perfect a security interest in equipment, inventory
      and
      general intangibles owned by each Debtor in the past five years; (d) each trade
      name or other name (other than its name set forth on the signature page hereto)
      used by each Debtor; and (e) each Debtor’s federal taxpayer identification
      number (and, during the four months preceding the date hereof, such Debtor
      has
      not had any other federal taxpayer identification number) and state
      organizational number. During the past four months preceding the date hereof,
      no
      Debtor has been known by any legal name different from the one set forth on
      the
      signature page hereto, nor has such Debtor been the subject of any merger or
      other corporate reorganization during the past five years. The name set forth
      on
      the signature page is the true and correct name of such Debtor. No
      Debtor
      will change its name or place of incorporation or organization or federal
      taxpayer identification number except upon 30 days’ prior written notice to the
      Bank.

    

    3.3 Insurance.  The
      Debtors shall keep the tangible Collateral insured at all times against loss
      by
      theft, fire and other casualties. Said insurance shall be issued by a company
      rated A or better by Best and shall be in amounts sufficient to protect the
      Bank
      against any and all loss or damage to the Collateral. The policy or policies
      which evidence said insurance shall be delivered to the Bank upon request,
      shall
      contain a lender loss payable clause in favor of the Bank, shall name the Bank
      as an additional insured, as its interest may appear, shall not permit
      amendment, cancellation or termination without giving the Bank at least 30
      days
      prior written notice thereof, and shall otherwise be in form and substance
      satisfactory to the Bank. Reimbursement under any liability insurance maintained
      by the Debtors pursuant to this Section 3.3 may be paid directly to the person
      who shall have incurred liability covered by such insurance. In the case of
      any
      loss to tangible Collateral, the proceeds shall be paid and used as follows:
      

     

    (a) if
      there
      is any Event of Default (whether before or after any event which caused any
      reimbursement under any insurance) has occurred and is continuing, such
      reimbursement shall be paid to the Bank for application to the Secured
      Liabilities.

    

    (b) if
      no
      Event of Default (whether before or after any event which caused any
      reimbursement under any insurance) has occurred and is continuing and such
      reimbursement is less than $250,000, the Debtors may use the proceeds of such
      insurance solely to repair or replace the property damaged, provided that if
      such repair or replacement cannot be accomplished within 180 days after such
      reimbursement amount is received or if the reimbursement amount is greater
      than
      $250,000, the proceeds of such insurance shall be paid to the Bank for
      application to the Secured Liabilities; and, provided, further, if the amount
      of
      such reimbursement is greater than $100,000, upon the request of the Bank,
      such
      insurance proceeds that are allowed to be used to repair or replace hereunder
      may be held by the Bank in a cash collateral account, and disbursed by the
      Bank
      as and when needed to pay for such allowed replacements and repairs (or applied
      to the Secured Obligations if Event of Default occurs).

    

    
      
        SECURITY
          AGREEMENT

         

      

      
        -4-

        
          

        

      

      
         

      

    

    The
      Debtors hereby appoint the Bank or any employee or agent of the Bank as Debtors'
      attorney-in-fact, which appointment is coupled with an interest and irrevocable,
      and, if such insurance claims or proceeds are required to be paid to the Bank,
      authorize the Bank or any employee or agent of the Bank, on behalf of the
      Debtors, to adjust and compromise any loss under said insurance and to endorse
      any check or draft payable to the Debtors in connection with returned or
      unearned premiums on said insurance or the proceeds of said insurance, and
      any
      amount so collected may be applied toward satisfaction of the Secured
      Liabilities, provided, however, that the Bank shall not be required hereunder
      so
      to act.

    

    3.4 Taxes,
      Etc.  The
      Debtors will pay promptly, and within the time that they can be paid without
      interest or penalty, any taxes, assessments and similar imposts and charges,
      not
      being contested in good faith, which are now or hereafter may become a Lien
      upon
      any of the Collateral. If the Debtors fail to pay any such taxes, assessments
      or
      other imposts or charges in accordance with this Section, the Bank shall have
      the option to do so and the Debtors agree to repay forthwith all amounts so
      expended by the Bank with interest at the prime-based rate set forth in the
      Loan
      Agreement . 

    

    3.5 Maintenance
      of Collateral.  The
      Debtors will cause the tangible Collateral material to the conduct of its
      business to be maintained and preserved in the same condition, repair and
      working order as when new, ordinary wear and tear excepted, and in accordance
      with any manufacturer's manual, and shall forthwith, or, in the case of any
      loss
      or damage to any of the tangible Collateral as quickly as practicable after
      the
      occurrence thereof, make or cause to be made all repairs, replacements, and
      other improvements which are necessary or desirable to such end. The Debtors
      shall promptly furnish to the Bank a statement respecting any material loss
      or
      damage to any of the tangible Collateral. The Debtors shall preserve and
      maintain all rights of the Debtors and the Bank in all material intangible
      Collateral, and will not subordinate, supplement
      or otherwise modify any claim or right of the Debtors with respect to any
      Collateral, or permit, consent or suffer to occur any of the foregoing, if
      the
      effect thereof is to impair, or is in any manner adverse to, the rights or
      interests of the Bank without the prior written consent of the
      Bank.

    

    3.6
       Tangible
      Property Location.

      of a warehouseman, bailee or other Person that has been notified of the security
      interest hereunder, consented to such security interest, waived any Lien it
      may
      have on such inventory and equipment and signed an agreement satisfactory to
      the
      Bank. Additionally,
      each Debtor will use commercially reasonable efforts
      to cause each lessor of real property to any Debtor to execute and deliver
      to
      the Bank an estoppel, waiver and consent agreement in form and substance
      acceptable to the Bank. All fixtures of any Debtor are located on the legal
      descriptions listed on Schedule 3.

      documents, certificated securities, instruments and tangible chattel paper

      Bank possession of all originals of all negotiable documents, certificated
      securities, instruments and tangible chattel paper acquired or held by such
      Debtor after the date hereof, in each case duly endorsed in blank and/or

      by,
      the Bank. The
      Debtors will cause each issuer of a letter of credit issued for the benefit
      of
      any Debtor at any time to consent to the assignment of proceeds of the letter
      of
      credit or otherwise give the Bank control of the related letter-of-credit right.
      With respect to any investment property (other than certificated securities)
      of
      any Debtor, such Debtor shall cause a control agreement satisfactory to the
      Bank
      relating to such investment property to be executed and delivered in favor
      of
      the Bank or otherwise take such actions to give the Bank control thereof. With

      interests or liens may be perfected by filing under any federal statute (except
      for certain Intellectual Property) other than as set forth on Schedule 8. Each
      Debtor agrees to promptly notify the Bank in writing if it acquires any
      Collateral covered by a certificate of title, any aircraft, aircraft engine,
      ship or railcar or any other asset of a type for which security interests or
      liens may be perfected by filing under any federal statute. The Debtors will
      take all further action and execute such other documents, if any, required
      by
      the Bank to grant the Bank a security interest all such Collateral.

    

    3.11 Special
      Rights Regarding Receivables.
      The
      Bank or any of its agents may, at any time and from time to time in its sole
      discretion following an Event of Default, verify, directly with each person
      (collectively, the "Obligors") which owes any Receivables to any Debtor, the
      Receivables in any reasonable manner. The Bank or any of its agents may, at
      any
      time from time to time after and during the continuance of an Event of Default,
      notify the Obligors of the security interest of the Bank in the Collateral
      and/or direct such Obligors that all payments in connection with such
      obligations and the Collateral be made directly to the Bank in the Bank's name.
      If the Bank or any of its agents shall collect such obligations directly from
      the Obligors, the Bank or any of its agents shall have the right to resolve
      any
      disputes relating to returned goods directly with the Obligors in such manner
      and on such terms as the Bank or any of its agents shall deem appropriate.
      The
      Debtors direct and authorize any and all of its present and future Obligors
      to
      comply with requests for information from the Bank, the Bank's designees and
      agents and/or auditors issued pursuant to this Section, relating to any and
      all
      business transactions between the Debtors and the Obligors. The Debtors further
      direct and authorize all of its Obligors upon receiving a notice or request
      sent
      by the Bank or the Bank's agents or designees pursuant to this Section to pay
      directly to the Bank any and all sums of money or proceeds now or hereafter
      owing by the Obligors to the Debtors, and any such payment shall act as a
      discharge of any debt of such Obligor to the Debtors in the same manner as
      if
      such payment had been made directly to the Debtors. The Debtors agree to take
      any and all action as the Bank may reasonably request to assist the Bank in
      exercising the rights described in this Section.

    REMEDIES

    

    4.1
      General
      Remedies.
      Upon
      the occurrence of any Event of Default, the Bank shall have and may exercise
      any
      one or more of the rights and remedies provided to it under this Agreement
      or
      any of the other Loan Documents or provided by law, including but not limited
      to
      all of the rights and remedies of a secured party under the UCC, and the Debtors
      hereby agree to assemble the Collateral and make it available to the Bank at
      a
      place to be designated by the Bank which is reasonably convenient to both
      parties, authorize the Bank to take possession of the Collateral with or without
      demand and in accordance with applicable law and to sell and dispose of the
      same
      at public or private sale and to apply the proceeds of such sale to the costs
      and expenses thereof (including reasonable attorneys' fees and disbursements,
      incurred by the Bank) and then to the payment and satisfaction of the Secured
      Liabilities. Any requirement of reasonable notice shall be met if the Bank
      sends
      such notice to the Debtors, by registered or certified mail, at least 10 days
      prior to the date of sale, disposition or other event giving rise to a required
      notice. The Bank may be the purchaser at any such sale. The Debtors expressly
      authorize such sale or sales of the Collateral in advance of and to the
      exclusion of any sale or sales of or other realization upon any other collateral
      securing the Secured Liabilities. The Bank shall have no obligation to preserve
      rights against prior parties, and the Bank shall have no obligation to clean-up
      or otherwise prepare the Collateral for sale. The Debtors hereby waive as to
      the
      Bank any right of subrogation or marshaling of such Collateral and any other
      collateral for the Secured Liabilities. To this end, the Debtors hereby
      expressly agree that any such collateral or other security of the Debtors or
      any
      other party which the Bank may hold, or which may come to the Bank or its,
      may
      be dealt with in all respects and particulars as though this Agreement were
      not
      in existence. The parties hereto further agree that public sale of the
      Collateral by auction conducted in any county in which any Collateral is located
      or in which the Bank or the Debtors does business after advertisement of the
      time and place thereof shall, among other manners of public and private sale,
      be
      deemed to be a commercially reasonable disposition of the Collateral. The
      Debtors shall be liable for any deficiency remaining after disposition of the
      Collateral. The Bank may comply with any applicable state or federal law
      requirements in connection with a disposition of the Collateral and compliance
      will not be considered to adversely affect the commercial reasonableness of
      any
      sale of the Collateral. The Bank may specifically disclaim any warranties of
      title or the like. If the Bank sells any of the Collateral upon credit, the
      Debtors will be credited only with payments actually made by the purchaser,
      received by the Bank and applied to the indebtedness of such purchaser. In
      the
      event any such purchaser fails to pay for the Collateral, the Bank may resell
      the collateral and the Debtors shall be credited with the proceeds of
      sale.

     

    4.2 Additional
      Remedies; Irrevocable Proxy.
      (a)
      Upon the occurrence and during the continuance of any Event of Default, the
      Bank
      shall have also the right to vote all investment property on all questions
      after
      giving notice to the applicable Debtor of its election to exercise such rights.
      In the absence of any such Event of Default, the applicable Debtor shall have
      the right to vote all investment property on all questions, provided
      that
      voting by the applicable Debtor of all investment property shall be in
      conformity with performance of the obligations of the applicable Debtor under
      the Loan Documents. 

    

    (b) Whenever
      an Event of Default has occurred and is continuing, the Bank may transfer into
      its name, or into the name of its nominee or nominees, any or all of the
      investment property and, as provided above, may vote any or all of the
      investment property (whether or not so transferred) and may otherwise act with
      respect thereto as though it were the outright owner thereof, the Debtors hereby
      irrevocably constituting and appointing the Bank as the proxy and
      attorney-in-fact of the Debtors, with full power of substitution, to do so.
      The
      Bank
      agrees that unless an Event of Default shall have occurred and be continuing,
      such Debtor shall have the exclusive voting power with respect to any securities
      constituting Collateral, provided that no vote shall be cast, or consent,
      waiver, or ratification given, or action taken by such Debtor that would violate
      any provision of the Loan Agreement or any other Loan Document.

      proceeds, stock
      rights, stock dividends, liquidating dividends, new securities, payments,
      distributions and proceeds (including cash dividends and sale proceeds) and
      other property to which any Debtor may become entitled by reason of the
      ownership of any investment property and other Collateral shall be delivered
      (properly endorsed where required hereby or requested by the Bank) to the Bank.
      

    

    (d) The
      Debtors agree that the proxy granted in this Section 5.2 is irrevocable and
      coupled with an interest and is and shall be both valid and irrevocable so
      long
      as the investment property is subject to this Agreement. The Debtors further
      acknowledge that the term of said proxy may exceed three years from the date
      hereof.

    

    4.3 Special
      Remedies Concerning Certain Collateral.

    

    (a) Upon
      the
      occurrence of any Event of Default, the Debtors shall, if requested to do so
      in
      writing, and to the extent so requested promptly collect and enforce payment
      of
      all amounts due the Debtors on account of, in payment of, or in connection
      with,
      any of the Collateral, hold all payments in the form received by the Debtors
      as
      trustee for the Bank, without commingling with any funds belonging to the
      Debtors, and forthwith deliver all such payments to the Bank with endorsement
      to
      the Bank's order of any checks or similar instruments. 

    

    (b) Upon
      the
      occurrence of any Event of Default, the Debtors shall, if requested to do so,
      and to the extent so requested, notify all Obligors and other persons with
      obligations to the Debtors on account of or in connection with any of the
      Collateral of the security interest of the Bank in the Collateral and direct
      such account debtors and other persons that all payments in connection with
      such
      obligations and the Collateral be made directly to the Bank. The Bank itself
      may, upon the occurrence of an Event of Default, so notify and direct any such
      account debtor or other person that such payments are to be made directly to
      the
      Bank. 

    

    (c) Upon
      the
      occurrence of an Event of Default, for purposes of assisting the Bank in
      exercising its rights and remedies provided to it under this Agreement, the
      Debtors (i) hereby irrevocably constitute and appoint the Bank its true and
      lawful attorney, for and in each Debtor's name, place and stead, to collect,
      demand, receive, sue for, compromise, and give good and sufficient releases
      for,
      any monies due or to become due on account of, in payment of, or in connection
      with the Collateral, (ii) hereby irrevocably authorize the Bank to endorse
      the
      name of the Debtors, upon any checks, drafts, or similar items which are
      received in payment of, or in connection with, any of the Collateral, and to
      do
      all things necessary in order to reduce the same to money, (iii) with respect
      to
      any Collateral, hereby irrevocably assent to all extensions or postponements
      of
      the time of payment thereof or any other indulgence in connection therewith,
      to
      each substitution, exchange or release of Collateral, to the addition or release
      of any party primarily or secondarily liable, to the acceptance of partial
      payments thereon and the settlement, compromise or adjustment (including
      adjustment of insurance payments) thereof, all in such manner and at such time
      or times as the Bank shall deem advisable and (iv) hereby irrevocably authorize
      the Bank to notify the post office authorities to change the address for
      delivery of the Debtors' mail to an address designated by the Bank, and the
      Bank
      may receive, open and dispose of all mail addressed to the Debtors.
      Notwithstanding any other provisions of this Agreement, it is expressly
      understood and agreed that the Bank shall have no duty, and shall not be
      obligated in any manner, to make any demand or to make any inquiry as to the
      nature or sufficiency of any payments received by it or to present or file
      any
      claim or take any other action to collect or enforce the payment of any amounts
      due or to become due on account of or in connection with any of the
      Collateral.

      right or remedy conferred
      upon or
      reserved to the Bank under any Loan Document is intended to be exclusive of
      any
      other right or remedy, and every right and remedy shall be cumulative in

      by

      and
      waiver of any default or forbearance on the part of the Bank in enforcing any

      FIFTH
      THIRD LEASING COMPANY,
      having
      an office at 38
      Fountain Square Plaza, Cincinnati, Ohio 45263,

      (“Lessee”). 

     

    TERMS
      AND CONDITIONS OF LEASE

    

    1.  Lease.
      Subject
      to the terms and conditions set forth herein, Lessor and Lessee shall execute
      and deliver Equipment Schedules (in form and substance as identified on
      Attachment 1 herein) pursuant to this Master Lease (each, an “Equipment
      Schedule”) and pursuant to each Equipment Schedule Lessor shall lease to Lessee
      the equipment and other property described on such Equipment Schedule (together
      with all parts, additions and accessories incorporated therein, and software
      incorporated therein, the “Equipment”). Each Equipment Schedule will incorporate
      by reference this Master Lease and will specify certain terms relating to the
      leasing of the Equipment (this Master Lease as incorporated into each Equipment
      Schedule, a “Lease”). Each Equipment Schedule, together with this Master Lease,
      shall constitute a separate and enforceable Lease. In the event that any term
      of
      any Equipment Schedule conflicts with or is inconsistent with any term of this
      Master Lease, the terms of the Equipment Schedule shall govern. As used herein,
      the term “Item of Equipment”, as it relates to any Equipment, shall have the
      meaning specified in the Equipment Schedule relating to such Equipment and
      if no
      such meaning is specified therein, “Item of Equipment” shall mean the Equipment
      as a whole.

     

    2.  Term.
      With
      respect to any Item of Equipment, unless otherwise specified on an Equipment
      Schedule, the initial term of lease shall commence on the earlier of (a) the
      date an Acceptance Certificate (as defined in Section 5)
      is
      executed with respect to such Item of Equipment, and (b) unless the Lessee
      rejects such Item of Equipment in a written notice to Lessor, ten (10) days
      after delivery of such Item of Equipment (the “Delivery and Acceptance Date”)
      and, unless earlier terminated as provided herein, shall expire on the
      Expiration Date (as defined in the Equipment Schedule relating to such Item
      of
      Equipment); provided,
      however, that
      the
      Base Lease Term or the then applicable Renewal Term shall be automatically
      extended for successive one month periods until either (a) the end of the Notice
      Period (as defined below) or (b) Lessor demanding return of the Equipment.
      As
      used herein, “Notice Period” shall mean the period ending on the latest of (i)
      the Expiration Date, (ii) one hundred eighty (180) days after the delivery
      by
      Lessee of its final written notice of its election to purchase or return the
      Equipment or to determine the Fair Market Value or Fair Market Rental Value,
      as
      applicable, in accordance with the options set forth in the Equipment Schedule
      and (iii) one hundred eighty (180) days after the delivery by Lessee of its
      election to return the Equipment. Lessee shall pay Basic Rent at the then
      current rate for each month during the automatic renewal term. As used herein,
      “Term” shall mean, collectively, the period from the Delivery and Acceptance
      Date to the Expiration Date and all Renewal Terms (as defined in the Equipment
      Schedule relating to such Equipment); provided,
      however,
      that
      this Master Lease shall be effective from and after the date of execution
      hereof. All tax and general indemnification obligations of Lessee hereunder
      shall survive the expiration, cancellation or other termination of the Term,
      and
      all payment obligations shall survive until indefeasible receipt by Lessor
      of
      such payment obligations. Provided that no Default or Event of Default (each
      as
      defined in Section 16)
      has
      occurred and is continuing, Lessor shall not interfere with Lessee’s quiet use
      and possession of the Equipment.

     

    3.  Rent.
      Lessee
      shall pay Lessor for the leasing of the Equipment hereunder the periodic rental
      payments (“Basic Rent”) on the dates (each a “Rent Payment Date”) and in the
      amounts set forth in the Equipment Schedule. Basic Rent together with all other
      additional amounts as may from time to time be payable under this Lease and
      the
      other Lease Documents (as defined in Section 4)
      is
      referred to herein as “Rent”). Rent shall be due whether or not Lessee has
      received any notice that such payments are due. All Rent shall be paid to Lessor
      at its address set forth in the Equipment Schedule, or as otherwise directed
      by
      Lessor in writing. If any Rent is not paid when due (or within 10 days
      thereafter) Lessee shall pay to Lessor a late payment fee equal to five percent
      (5%) of the amount of such Rent.

     

    
      
         

      

      
         

        
          

        

      

      
         

      

    

    4.  Net
      Lease.
      Each
      Lease shall constitute a non-cancelable net lease, it being the intention of
      the
      parties that all costs, expenses and liability associated with the Equipment
      or
      its lease shall be borne by Lessee. Lessee’s obligation to pay Rent and
      otherwise to perform its obligations under this Lease and each other document
      and agreement executed in connection with this Lease (together with the Lease,
      collectively, the “Lease Documents”) shall be irrevocable, absolute and
      unconditional and shall not be subject to defense, counterclaim, set-off,
      diminution, abatement or recoupment for any reason whatsoever, and Lessee waives
      all rights to terminate or surrender this Lease for any reason except as
      expressly set forth in this Lease, including, without limitation, defect in
      the
      Equipment or non-performance by Lessor. All Rent shall be paid without reduction
      or deduction whatsoever, including any reduction or deduction for any Tax (as
      defined in Section 18).

     

    5.  Acceptance.
      Upon
      delivery of the Equipment, Lessee shall promptly inspect and test such Equipment
      and, if acceptable to Lessee, accept such Equipment and deliver to Lessor a
      certificate of acceptance, in form and substance reasonably satisfactory to
      Lessor (“Acceptance Certificate”). Lessee represents that it has selected both
      (a) the Equipment, and (b) the manufacturer, vendor or other supplier of the
      Equipment (the “Supplier”) without assistance from Lessor and either is a party
      to, or has received a copy of, each agreement and document by which Lessor
      acquired the Equipment or the right to possession and use of the Equipment
      (including any documents or agreements with the Supplier (collectively, the
      “Supply Contract”)) prior to the Delivery and Acceptance Date. Lessee hereby
      assumes the risks, burdens, and obligations to any manufacturer or vendor of
      any
      Item of Equipment on account of nondelivery, nonacceptance or nonperformance
      of
      the Equipment. 

     

    6.  Disclaimer
      of Warranties.
      THE
      EQUIPMENT IS BEING LEASED TO THE LESSEE BY THE LESSOR “AS IS, WHERE IS”. LESSOR
      DOES NOT MAKE, HAS NOT MADE, SHALL NOT BE DEEMED TO MAKE OR HAVE MADE, AND
      EXPRESSLY DISCLAIMS TO LESSEE ANY WARRANTY OR REPRESENTATION, EITHER EXPRESS
      OR
      IMPLIED, WRITTEN OR ORAL, WITH RESPECT TO THE EQUIPMENT LEASED HEREUNDER OR
      ANY
      COMPONENT THEREOF, INCLUDING, WITHOUT LIMITATION, ANY WARRANTY AS TO DESIGN,
      COMPLIANCE WITH ANY LAW, RULE, SPECIFICATION, OR CONTRACT PERTAINING THERETO,

      FITNESS FOR ANY PURPOSE,

      OPERATION, SAFETY, PATENT, TRADEMARK OR COPYRIGHT INFRINGEMENT, OR TITLE, IT
      BEING AGREED THAT ALL SUCH RISKS, AS BETWEEN LESSOR AND LESSEE, ARE TO BE BORNE
      BY LESSEE. Lessee’s execution and delivery of an Acceptance Certificate shall be
      conclusive evidence as between Lessor and Lessee that the Items of Equipment
      referred to therein are acceptable for all purposes hereof.

    8.  Use
      and Maintenance; Alterations.

     

    (a)  Lessee
      covenants and agrees that it: (i) shall use the Equipment solely in the conduct
      of its business, for the purpose, and in the manner, for which the Equipment
      was
      designed, (and shall not permanently discontinue use of the Equipment without
      Lessor’s prior express written consent); (ii) shall operate, maintain, service
      and repair the Equipment, and maintain all records and other materials relating
      thereto, (A) in accordance and consistent with (1) the Supplier’s
      recommendations all maintenance and operating manuals or service agreements,
      whenever furnished or entered into, including any subsequent amendments or
      replacements thereof, issued by the Supplier or other service provider
      (including requiring all components, fuels and fluids installed in or used
      on
      the Equipment to meet the standards specified by the Supplier from time to
      time), (2) the requirements of all applicable insurance policies, (3) the Supply
      Contract, so as to preserve all of Lessee’s and Lessor’s rights thereunder,
      including all rights to any warranties, indemnities or other rights or remedies,
      (4) all applicable laws, and (5) the prudent practice of other similar companies
      in the same business as Lessee, but in any event, to no lesser standard than
      that employed by Lessee for comparable equipment owned or leased by it; and
      (B)
      without limiting the foregoing, so as to cause the Equipment to be in good
      repair and operating condition, except for ordinary wear and tear resulting
      despite Lessee’s full compliance with the terms hereof; (iii) shall not
      discriminate against the Equipment with respect to scheduling of maintenance,
      parts or service; (iv) shall not change the location of any Equipment as
      specified in the Equipment Schedule without the prior written consent of Lessor;
      and (v) to the extent requested by Lessor, shall cause each Item of the
      Equipment to be continually marked, in a plain and distinct manner, with the
      name of Lessor followed by the words “Owner and Lessor,” or other appropriate
      words designated by Lessor on labels furnished by Lessor. If the location for
      any Equipment specified in the Equipment Schedule is a facility leased by Lessee
      or owned by Lessee subject to one or more mortgage liens, upon the request
      of
      Lessor, Lessee will obtain an Access and Waiver Agreement in form and substance
      satisfactory to Lessor (as identified as Attachment 2 herein) from the landlord
      or lessors or mortgagees of such facility.

     

    (b)  Lessee,
      at its own cost and expense, will promptly replace all parts, appliances,
      systems, components, instruments and other equipment (“Parts”) incorporated in,
      or installed on, the Equipment which may from time to time become worn out,
      lost, stolen, destroyed, seized, confiscated, damaged beyond repair or
      permanently rendered unfit for use for any reason whatsoever. In addition,
      in
      the ordinary course of maintenance, service repair, overhaul or testing, Lessee
      may remove any Parts, whether or not worn out, lost, stolen, destroyed, seized,
      confiscated, damaged beyond repair or permanently rendered unfit for use,
provided
      that
      Lessee shall replace such Parts as promptly as practicable. All replacement
      Parts shall be free and clear of all Liens (as defined in Section 8(c))
      and
      shall be in as good an operating condition as, and shall have a value and
      utility at least equal to, the Parts replaced, assuming such replaced Parts
      were
      in the condition and repair required to be maintained by the terms hereof.
      Any
      replacement Part installed, or incorporated on, the Equipment shall be
      considered an accession to such Equipment and title to such replacement Part
      shall immediately vest in Lessor without cost or expense to Lessor.

     

    
      
         

      

      
        3

        
          

        

      

      
         

      

    

    (c)  Lessee
      will keep the Equipment and its interest therein free and clear of all liens,
      claims, mortgages, charges and encumbrances of any type regardless of how
      arising (“Liens”) other than any Lien arising out of claims against Lessor not
      relating to the lease of the Equipment to Lessee (“Permitted Liens”). Lessee
      will defend, at its own expense, Lessor’s title to the Equipment from all such
      Liens. If any Lien shall attach to any item of Equipment, Lessee will provide
      written notification to Lessor within five (5) business days after Lessee
      receives notice of any such attachment stating the full particulars thereof
      and
      the location of such Equipment on the date of such notification. 

     

    (d)  At
      its
      sole option, Lessee may make any alteration, modification or attachment to
      the
      Equipment deemed appropriate by Lessee, provided
      that
      such alteration, modification, attachment is of a type which is readily
      removable without damage to the Equipment does not decrease the value,
      condition, utility or useful life of the Equipment or cause such Equipment
      to
      become “limited use property” (as defined in Revenue Procedure 2001-28, 2001-19
      I.R.B. 1156 or any successor publication or Treasury Regulation issued pursuant
      to the Internal Revenue Code of 1986 (as amended, supplemented or modified
      from
      time to time, the “Code”)), a fixture (as defined in the Uniform Commercial Code
      as in effect in any applicable jurisdiction), or real property or affect the
      insurability or impair any manufacturer’s warranty with respect to the
      Equipment. All alterations, modifications and attachments of whatsoever kind
      or
      nature made to any item of Equipment that cannot be removed without damaging
      or
      reducing the functional capability, economic value or insurability of the item
      of Equipment or impairing any manufacturer’s warranty shall only be made with
      the prior written consent of the Lessor and shall be deemed to be part of the
      Equipment. Under no circumstance shall any alteration, modification or
      attachment be subjected by Lessee to any encumbrance other than this
      Lease.

     

    9.  Assignment
      and Sublease.
      Lessee
      shall not sublease or otherwise relinquish possession of any Item of Equipment,
      or assign, transfer or encumber its rights, interests or obligations hereunder
      or under any Equipment Schedule executed pursuant hereto unless expressly
      permitted pursuant to the terms of the Equipment Schedule relating to such
      Equipment. No assignment, transfer or sublease, in any event, shall relieve
      Lessee of, and Lessee shall remain primarily liable for, its obligations under
      each Lease Document.

     

    10.  Insurance. 

     

    (a)  Lessee
      shall provide, maintain and pay for insurance coverage with respect to the
      Equipment, insuring against, among other things, the
      loss,
      theft, damage, or destruction of the Equipment, in an amount not less than
      the
      Stipulated Loss Value (as defined in the applicable Equipment Schedule) of
      such
      Equipment at any time; and public liability and property damage with respect
      to
      the use or operation of the Equipment, in the amounts set forth in the
      applicable Equipment Schedule. All insurance against loss shall name Lessor
      as
      the sole loss payee and all liability insurance shall name Lessor and its
      Assignees (as defined in Section 20)
      and
      their subsidiaries and affiliated companies, and their successors and assigns
      as
      additional insureds. All of such insurance shall be in form (including all
      endorsements required by Lessor), and with companies, reasonably satisfactory
      to
      Lessor.

     

    (b)  All
      policies of insurance required hereunder shall (i) provide that any
      cancellation, expiration, lapse, or material modification shall not be effective
      as to the Lessor for a period of thirty (30) days after receipt by Lessor of
      written notice thereof; (ii) provide that premiums may be paid by the Lessor,
      but without liability on the part of the Lessor for such premiums; (iii) be
      primary without any right of set-off or right of contribution from any other
      insurance carried by the Lessor; (iv) contain breach of warranty provisions
      providing that, in respect of the interests of the Lessor, the insurance shall
      not be invalidated by any action, inaction or breach of warranty, declaration,
      or condition by the Lessee or any other person or by any fact or information
      known to Lessor; and (v) waive any right of subrogation against Lessor. Prior
      to
      the Delivery and Acceptance Date for any Item of Equipment, and thereafter,
      not
      less than 15 days prior to each renewal or replacement of such insurance, Lessee
      will deliver to Lessor certificates issued by the insurance carriers thereunder
      evidencing the insurance required to be maintained pursuant to this
      Lease.

    (c)  The
      proceeds (if any) of the insurance maintained by Lessee that are received with
      respect to the loss or damage of any Equipment, shall be applied and paid
first,
      to
      Lessor for any amount then due and payable by Lessee under this Lease,
second,
      if an
      Event of Loss (as defined in Section 11)
      has
      occurred, to Lessor for the payment of Stipulated Loss Value or otherwise,
      to
      Lessee for its reasonable, documented, out-of-pocket costs to repair or replace
      such item of Equipment pursuant to Section 11(b)(i),
      to
      the extent that such repairs or replacements were necessitated by the occurrence
      of the loss for which such proceeds were paid, third,
      to
      Lessee to reimburse Lessee for any Stipulated Loss Value actually paid to,
      and
      retained by Lessor and fourth,
      any
      excess to Lessor. Proceeds of any liability insurance shall promptly be paid
      to
      the party entitled thereto.

     

    11.  Risk
      of Loss; Damage to Equipment.

     

    (a)  Lessee
      shall bear the entire risk of loss and damage to any and all Items of Equipment
      from any cause whatsoever, whether or not insured against, during the Term
      until
      the Equipment is returned to Lessor in accordance with Section 14
      hereof.
      No loss or damage shall relieve Lessee of the obligation to pay Rent or of
      any
      other obligation under this Lease. An “Event of Loss” shall be deemed to have
      occurred with respect to any Item of Equipment if such Item of Equipment or
      any
      material part thereof has been lost, stolen, requisitioned or condemned by
      any
      governmental authority, damaged beyond repair or damaged in such a manner that
      results in an insurance settlement on the basis of an actual or arranged total
      loss.

     

    (b)  Upon
      any
      loss or damage to any Item of Equipment not constituting an Event of Loss,
      Lessee will promptly, and in any event within thirty (30) days of such loss
      or
      damage (or such longer period as Lessor shall determine in its sole discretion),
      place such Item of Equipment in good condition and repair as required by the
      terms of this Lease. If an Event of Loss to any Item of Equipment has occurred,
      Lessee shall immediately notify Lessor of same, and at the option of Lessor,
      Lessee shall: (i) not more than thirty (30) days following such Event of Loss
      (or such longer period as Lessor shall determine in its sole discretion) replace
      such Item of Equipment with replacement equipment (acceptable to Lessor) in
      as
      good condition and repair, and with the same value remaining useful economic
      life and utility, as such replaced Item of Equipment immediately preceding
      the
      Event of Loss (assuming that such replaced Item of Equipment was in the
      condition required by this Lease), which replacement equipment shall
      immediately, and without further act, be deemed to constitute Items of Equipment
      and be fully subject to this Lease as if originally leased hereunder and shall
      be free and clear of all Liens; or (ii) pay to Lessor on the next succeeding
      Rent Payment Date the sum of (A) all Rent due and owing hereunder with respect
      to such Item of Equipment (at the time of such payment) including all Basic
      Rent
      payable on such Rent Payment Date plus (B) the Stipulated Loss Value as of
      such
      Rent Payment Date with respect to such Item of Equipment. Upon Lessor’s receipt
      of the payment required under subsection (ii) above, Lessee shall be entitled
      to
      Lessor’s interest in such Item of Equipment, in its then condition and location,
“as is” and “where is”, without any representations or warranties, express or
      implied.

     

    12.  Financial,
      Other Information and Notices.
      

     

    (a)  Lessee
      shall maintain a standard and modern system for accounting and shall furnish
      to
      Lessor:

     

    
      
         

      

      
        5

        
          

        

      

      
         

      

    

    (i)  Within
      forty-five (45) days after the end of each quarter, a copy of Lessee’s
      internally prepared consolidated financial statements for that quarter and
      for
      the year to date in a form reasonably acceptable to Lessor, prepared and
      certified as complete and correct, subject to changes resulting from year-end
      adjustments, by the chief financial officer of Lessee. 

     

    (ii)  Within
      one
      hundred twenty (120)
      days
      after the end of each fiscal year, a copy of Lessee’s consolidated year end
      financial statements audited by a firm of independent certified public
      accountants acceptable to Lessor (which acceptance shall not be unreasonably
      withheld) and accompanied by an audit opinion of such accountants without
      qualification. 

     

    All
      such
      financial statements shall be prepared in accordance with generally accepted
      accounting principles, consistently applied. In the event Lessee is a publicly
      held stock company domiciled in the United States, and Lessee files its
      financial statements on public record in accordance with the requirements set
      forth by the Securities and Exchange Commission, then Lessor shall deem Lessee
      to be in compliance with the financial reporting timing requirements set forth
      above.

     

    (b)  Lessee
      shall provide prompt written notice to Lessor (i) of any Event of Default (ii)
      of any loss or damage to any Item of Equipment or any Event of Loss with respect
      to any Item of Equipment, and (iii) any existing or threatened investigation,
      claim or action by any governmental authority which could adversely affect
      the
      Equipment or this Lease.

     

    (c)  Lessee
      shall furnish such other information as Lessor may reasonably request from
      time
      to time relating to the Equipment, this Lease or the operation or condition
      of
      Lessee including, without limitation, such additional financial statements
      of
      the Lessee for such periods as Lessor may request. 

     

    13.  Inspections.
      Lessor
      may from time to time during Lessee’s normal business hours, inspect the
      Equipment and Lessee’s records with respect thereto in a reasonable manner.
      Lessee shall cooperate with Lessor in scheduling such inspection and in making
      the Equipment available for inspection by Lessor or its designee at a single
      location as reasonably specified by Lessee. Lessee will, upon reasonable
      request, provide a report on the condition of the Equipment, a record of its
      maintenance and repair, a summary of all items suffering an Event of Loss,
      a
      certificate of no Event of Default, or such other information or evidence of
      compliance with Lessee’s obligations under the Lease as Lessor may reasonably
      request.

     

    14.  Condition
      Upon Return.
      At the
      expiration of the Term, unless Lessee has elected to purchase the Equipment
      in
      accordance with the terms of the Equipment Schedule, Lessee shall promptly,
      at
      its own cost and expense: (a) perform any testing and repairs required to place
      each Item of Equipment in the same condition and appearance as when received
      by
      Lessee (reasonable wear and tear excepted) and in good working order for its
      originally intended purpose and eligible for manufacturer’s maintenance (if
      available), free of all Lessee’s markings and free of all Liens other than
      Permitted Liens; (b) if de-installation, disassembly or crating is required,
      cause such Items of Equipment to be de-installed, disassembled and crated by
      an
      authorized manufacturer’s representative or such other service person as is
      reasonably satisfactory to Lessor; and (c) return such Items of Equipment in
      the
      condition and in the manner specified in the Equipment Schedule (collectively,
      the “Return Condition”). The Equipment, as returned, will include related
      maintenance logs, operating manuals, and other related materials. All operating
      manuals for the Equipment must be returned to Lessor undamaged and containing
      all pages. If lost or destroyed, Lessee shall, at its own expense, provide
      replacement operating manuals. Lessor may, but is not required to, inspect
      the
      Equipment prior to its return. If Lessor determines that the Equipment does
      not
      conform to the Return Condition, Lessor will promptly notify Lessee of such
      determination specifying the repairs or refurbishments needed to place the
      Equipment in the Return Condition. Lessor may, at its option, either require
      Lessee to effect such repairs or itself effect such repairs. In either case,
      all
      costs associated with any repairs and inspections will be paid by Lessee. Until
      Lessee has returned the Equipment in compliance with the requirements of this
      Lease, the Lease shall continue in full force and effect and Lessee shall
      continue to pay Rent notwithstanding any expiration or termination of the Term
      through and including the date on which the Equipment is accepted for return
      by
      Lessor as conforming with the Return Condition.

      Lessee
      represents and warrants as of the date of execution and delivery of this Master

      pending or, to the knowledge of Lessee, threatened, before any court or

      the financial statements of Lessee which have been delivered to Lessor have
      been

      of its jurisdiction of organization without giving to Lessor at least thirty
      (30) days prior written notice thereof; (h) the Equipment will always be used
      for business or commercial, and not personal, purposes; (i) Lessee is not in
      default under any obligation for borrowed money, for the deferred purchase
      price
      of property or any lease agreement which, either individually or in the

      Lease.

      Each
      of the following events constitutes an “Event of Default” hereunder and any
      event that, with the passage of time or the giving of notice, or both, would

      substantial part of its property; (vi) Lessee fails to return the Equipment

      Term; (vii) a default shall have occurred and be continuing under any contract,

      individuals who as of the date of this Agreement are members of the Board of

      that if the election, or nomination for election by the Lessee’s shareholders,
      of any new director was approved by a vote of at least a majority of the
      Incumbent Board, such new director shall, for purposes of this Agreement, be
      considered as a member of the Incumbent Board.

     

    (b)  Upon
      the
      occurrence of an Event of Default, Lessor may exercise any one or more of the
      following remedies and any additional rights and remedies permitted by law
      (none
      of which shall be exclusive) and shall be entitled to recover all its reasonable
      costs and expenses including incidental and consequential damages (as described
      in Section 2A-530 of the Uniform Commercial Code) and attorneys’ fees in
      enforcing its rights and remedies:

     

    (i)  Lessee
      shall upon demand assemble or cause to be assembled any or all of the Equipment
      at a location designated by Lessor; and/or to return promptly, at Lessee’s
      expense, any or all of the Equipment to Lessor at such location, in the
      condition and otherwise in accordance with all of the terms of Section 14
      hereof; and/or 

     

    (ii)  Lessor
      may itself or by its agents without breach of the peace or with court order
      or
      other process of law, enter upon the premises of Lessee or any other location
      where the Equipment is located and take possession of and render unusable by
      Lessee any or all of the Equipment, wherever it may be located, without any
      court order or other process of law and without liability for any damages
      occasioned by such taking of possession; and/or

     

    (iii)  Sell,
      re-lease or otherwise dispose of any or all of the Equipment, whether or not
      in
      Lessor’s possession, at public or private sale with or without notice to Lessee,
      with the right of Lessor to purchase and apply the net proceeds of such
      disposition, after deducting all costs of such disposition (including but not
      limited to costs of transportation, possession, storage, refurbishing,
      advertising and brokers’ fees), to the obligations of Lessee under this Lease,
      with Lessee remaining liable for any deficiency and with any excess being
      retained by Lessor, or retain any and all of the Equipment; and/or

     

    
      
         

      

      
        8

        
          

        

      

      
         

      

    

    (iv)  Cancel
      such Equipment Schedule as to any or all of the Equipment; and/or

     

    (v)  Proceed
      by appropriate court action, either at law or in equity (including an action
      for
      specific performance), to enforce performance by Lessee or to recover damages
      associated with such Event of Default; or exercise any other right or remedy
      available to Lessor at law or in equity; and/or

     

    (vi)  By
      offset, recoupment or other manner of application, apply any security deposit,
      monies held in deposit or other sums then held by Lessor or any affiliate of
      Lessor, and with respect to which Lessee has an interest, against any
      obligations of Lessee arising under this Lease or any other Lease Document,
      whether or not Lessee has pledged, assigned or granted a security interest
      to
      Lessor in any or all such sums as collateral for said obligations.

     

    (c)  In
      addition to the foregoing, Lessee shall pay to Lessor on demand the sum of
      (i)
      any and all Rent which is then due or which has accrued to the date of demand
      and (ii) at Lessor’s option (A) an amount equal to the Stipulated Loss Value (as
      set forth in the related Equipment Schedule) as of the Rent Payment Date on
      or
      immediately preceding the date of demand for the Items of Equipment as Lessor
      shall specify or (B) all Basic Rent and all other sums, including any tax
      indemnities becoming due as a result of such Event of Default, for the Term
      (including any mandatory Renewal Term) and all amounts due upon the expiration
      of the Term including any return fees and/or any amounts due with respect to
      the
      mandatory purchase of the Equipment becoming due under this Lease from the
      date
      of demand to the Expiration Date for such Items of Equipment plus the assumed
      residual value of such Equipment (as determined by Lessor). The Lessor and
      Lessee agree that Lessor shall be entitled to such amount as damages for loss
      of
      bargain and not as a penalty and that such amount is reasonable in light of
      the
      anticipated harm to Lessor caused by an Event of Default. 

     

    (d)  If
      Lessee
      pays the full amount referred to in Section 16(c) to Lessor prior to the
      termination of this Lease as it relates to such Items of Equipment, title to
      the
      relevant Equipment shall immediately vest in Lessee without representation
      or
      warranty by Lessor. If Lessee fails to pay such amount and Lessor subsequently
      sells, releases or otherwise disposes of such Items of Equipment, the amount
      due
      from Lessee under Section 16(c) shall be reduced by an amount equal to (i)
      the
      actual cash proceeds received and retained by Lessor upon any sale or
      disposition or (ii) if Lessor leases such Equipment by a lease agreement
      substantially similar to this Lease, the present value of the rents (discounted
      at the Prime Rate as announced by Fifth Third Bank and in effect at the time
      of
      demand plus 2.00%) payable under such subsequent Lease for the remaining Term
      of
      this Lease (without regard to any Renewal Terms other than the then current
      Renewal Term (if applicable)), in each case, net of all costs and expenses
      incurred in connection with such sale, disposition or lease including any
      incidental damages.

     

    (e)  A
      cancellation or termination hereunder shall occur only upon written notice
      by
      Lessor to Lessee, and only with respect to such Items of Equipment as Lessor
      specifically elects to cancel or terminate by such notice. Except as to any
      such
      Items of Equipment with respect to which there is a cancellation or termination,
      this Lease shall remain in full force and effect and Lessee shall be and remain
      liable for the full performance of all its obligations under this
      Lease.

     

    (f)  Lessee
      shall indemnify, defend and hold Lessor harmless for any loss, personal injury
      (including death), or damage to property, suffered by Lessor, its employees
      or
      any of its agents in connection with its entry onto the premises of Lessee
      or
      any third party hereunder. Each of the rights and remedies of Lessor hereunder
      and under the other Lease Documents is in addition to all of its other rights
      and remedies hereunder, under the other Lease Documents and under applicable
      law
      and nothing in this Lease or any other Lease Document shall be construed as
      limiting any such right or remedy. Lessor’s failure to exercise or delay in
      exercising any right, power or remedy available to Lessor shall not constitute
      a
      waiver or otherwise affect or impair its rights to the future exercise of any
      such right, power or remedy. Waiver by Lessor of any Event of Default shall
      not
      be a waiver by Lessor of any other or subsequent Events of Default.

    17.  General
      Indemnification.
      Lessee
      shall pay, and shall indemnify and hold Lessor, its directors, officers, agents,
      employees, successors and assigns (each an “Indemnitee”) harmless on an
      after-tax basis from and against, any and all liabilities, causes of action,
      claims, suits, penalties, damages, losses, costs or expenses (including
      attorneys’ fees), obligations, liabilities, demands and judgments, and Liens, of
      any nature whatsoever (collectively, a “Liability”) arising out of or in any way
      related to: (a) the Lease Documents, (b) the manufacture, purchase,
      ownership, title, selection, acceptance, rejection, possession, lease, sublease,
      operation, use, maintenance, documenting, inspection, control, loss, damage,
      destruction, removal, storage, surrender, sale, use, condition, delivery,
      nondelivery, return or other disposition of or any other matter relating to
      any
      Item of Equipment or any part or portion thereof (including, in each case and
      without limitation, latent or other defects, whether or not discoverable, any

      Liabilities in any way relating to or arising out of injury to persons,
      properties or the environment or any and all Liabilities based on strict
      liability in tort, negligence, breach of warranties or violations of any
      regulatory law or requirement, (c) a failure to comply fully with applicable
      law
      and (d) Lessee’s failure to perform any covenant, or Lessee’s breach of any
      representation or warranty, hereunder; provided,
      that the
      foregoing indemnity shall not extend to the Liabilities to the extent resulting
      solely from the gross negligence or willful misconduct of an
      Indemnitee.

     

    18.  General
      Tax Indemnification.
      Lessee
      shall pay when due and shall indemnify and hold each Indemnitee harmless from
      and against (on an after-tax basis) any and all taxes, fees, withholdings,
      levies, imposts, duties, assessments and charges of any kind and nature
      (“Taxes”) arising out of or related to this Lease or any other Lease Document
      (together with interest and penalties thereon and including, without limitation,
      sales, use, gross receipts, personal property, real property, real estate
      excise, ad
      valorem,
      business and occupational, value added, leasing, leasing use, documentary,
      stamp
      or other taxes imposed upon or against any Indemnitee, Lessee or any Equipment
      by any governmental authority with respect to any Equipment or the
      manufacturing, ordering, sale, purchase, shipment, delivery, acceptance or
      rejection, ownership, titling, registration, leasing, subleasing, possession,
      use, operation, removal, return or other dispossession thereof or upon the
      rents, receipts or earnings arising therefrom or upon or with respect to this
      Lease, whether payable at the inception of a Lease, during the Term thereof
      or
      at the expiration thereof, excepting only all United States federal, state
      and
      local taxes based on or measured by Lessor’s net income. Whenever this Lease or
      any other Lease Document terminates as to any Item of Equipment, Lessee shall,
      upon written request by Lessor, advance to Lessor the amount estimated by Lessor
      to be the personal property or other taxes on such Item of Equipment which
      are
      not yet payable, but for which Lessee is responsible. Lessor shall, at Lessee’s
      request, provide Lessee with Lessor’s method of computation of any estimated
      taxes.
      Except
      as otherwise provided in the Equipment Schedule relating to any Equipment,
      upon
      receipt of any tax bill relating to such Equipment from a relevant taxing
      authority, Lessor will pay the Tax identified on such tax bill. Lessee will,
      on
      demand, (a) reimburse Lessor for the amount of such Tax paid to such taxing
      authority and (b) pay to Lessor a fee (as identified by Lessor from time to
      time) relating to the administration of such payment.

    19.  Ownership.
      Title
      to the Equipment shall at all times remain in Lessor, and Lessee shall acquire
      no ownership, title, property, right, equity or interest in the Equipment other
      than its leasehold interest solely as Lessee subject to all the terms and
      conditions hereof. This Lease, is intended to be a “finance lease” solely for
      the purposes of Article 2A of the Uniform Commercial Code as that term is
      defined in Article 2A of the Uniform Commercial Code. To the extent permitted
      by
      applicable law, Lessee (a) waives any and all rights and remedies of Lessee
      under Sections 2A-508 through 2A-522 of the Uniform Commercial Code and (b)
      any
      rights now or hereafter conferred by statute or otherwise to recover incidental
      or consequential damages from Lessor for any breach or any other reason
      whatsoever. If, notwithstanding the express intent of the parties, a court
      of
      competent jurisdiction determines that any Equipment Schedule is not a “finance
      lease”, the parties agree that in such event (i) (A) in order to secure the
      prompt payment of Rent under and with respect to this Lease, and the performance
      and observance by Lessee of all the agreements, covenants and provisions hereof
      (collectively, the “Obligations”), Lessee hereby grants to Lessor a first
      priority security interest in all of Lessee’s right, title and interest in the
      following (whether now existing or hereafter created and whether now owned
      or
      hereafter acquired): (1) the Equipment (including, without limitation, all
      inventory, equipment, fixtures or other property comprising the same), and
      general intangibles relating thereto, (2) additions, attachments, accessories
      and accessions thereto whether or not furnished by the Supplier of such
      Equipment, (3) all subleases (including the right to receive any payment
      thereunder and the right to make any election or determination or give any
      consent or waiver thereunder), chattel paper, accounts, security deposits and
      bills of sale relating thereto, (4) any and all substitutions, replacements
      or
      exchanges for any such Equipment or other collateral, and (5) any and all
      products and proceeds of any collateral hereunder (including all insurance
      and
      requisition proceeds and all other payments of any kind with respect to the
      Equipment and other collateral in and against which a security interest is
      granted hereunder and (B) Lessee agrees that with respect to the Equipment,
      in
      addition to all of the other rights and remedies available to Lessor hereunder
      upon the occurrence of an Event of Default, Lessor shall have all of the rights
      and remedies of a secured party under the Uniform Commercial Code; and (ii)
      the
      original principal amount of the obligations hereunder shall be an amount equal
      to the Lessor’s Capitalized Cost, and that such principal amount shall accrue
      interest at the lesser of (x) the maximum lawful rate permitted by applicable
      law or (y) the implicit interest rate reflecting Lessor’s financial assumptions
      at the time of the execution of the Lease (including any assumed residual value
      at the end of the Term as determined by Lessor. Lessee hereby authorizes Lessor
      to file, solely at the expense of Lessee, any Uniform Commercial Code financing
      statements or other similar documents that Lessor reasonably deems necessary
      or
      advisable to protect its interest. Lessee agrees promptly to execute and deliver
      to Lessor such further documents or other assurances, and to take such further
      action, including obtaining landlord and mortgagee waivers, as Lessor may from
      time to time reasonably request.

     

    20.  Assignment
      by Lessor.
      Lessor
      may at any time assign, grant a security interest in, or otherwise dispose
      of
      (individually or collectively, a “transfer”), all or any portion of its rights,
      title or interests in, to and under this Lease, any Equipment Schedule or any
      Item of Equipment, together or separately, to one or more persons or entities
      (each, an “Assignee”). Upon any such transfer, this Lease shall remain in full
      force and effect. If Lessee is given notice of any such transfer, it shall
      acknowledge receipt thereof in writing and execute, or otherwise authenticate,
      such further instruments as may be reasonably requested by Assignee with respect
      to such transfer, including without limitation, a consent certifying certain
      material facts and circumstances related to this Lease and the Equipment. Unless
      otherwise expressly agreed by Assignee, Assignee shall not assume any of the
      obligations of Lessor under this Lease. Upon written notice to Lessee of an
      assignment, Lessee agrees to pay the Rent with respect to the Items of Equipment
      covered by such assignment to such Assignee in accordance with the instructions
      specified in such notice and Lessee shall not assert against Assignee any
      defense, counterclaim or offset that Lessee may have against Lessor. All
      obligations and liabilities of Lessee to Lessor under this Lease (including,
      without limitation, any schedules, exhibits, riders or other attachments
      attached hereto or otherwise incorporated herein) are also hereby made for
      the
      express benefit of Assignee.

     

    21.  Miscellaneous.

      shall pay all reasonable costs and expenses of Lessor, including, without
      limitation, reasonable attorneys’ and other professional fees, the fees of any

      to
      any sale or re-lease of the Equipment (including storage costs), incurred by
      Lessor in the preparation, negotiation and execution of this Lease or any
      amendment or supplement hereto, enforcing any of the terms, conditions or
      provisions hereof and in protecting Lessor’s rights hereunder.

     

    (b)  This
      Lease shall be governed by and construed in accordance with the laws of the

      each
      of the parties hereto (i) accepts the nonexclusive jurisdiction of such courts
      and any related appellate court and agrees to be bound by any judgment rendered
      by any such court in connection with any such proceeding and (ii) waives any
      objection it may now or hereafter have as to the venue of any such proceeding
      brought in such court or that such court is an inconvenient forum. EACH OF
      THE
      LESSEE AND LESSOR HEREBY WAIVES THE RIGHT TO TRIAL BY JURY IN ANY LAWSUIT OR
      PROCEEDING ARISING OUT OF OR IN ANY WAY RELATING TO THIS LEASE, ANY EQUIPMENT
      SCHEDULE, OR ANY OTHER LEASE DOCUMENT AND ANY ASSIGNMENT, SUBLEASE OR OTHER
      DOCUMENT EXECUTED IN CONNECTION THEREWITH.

      performance under the Lease Documents. Any failure of Lessor to require strict
      performance by Lessee or any waiver by Lessor of any provision herein shall

    (g)  Any
      provision of this Lease which is prohibited or unenforceable in any jurisdiction
      shall, as to such jurisdiction, be ineffective to the extent of such prohibition

      Lessee
      acknowledges and agrees that use of BillPayer 2000®
      shall be
      governed by the BillPayer 2000®
      Terms
      and Conditions, and Lessee hereby acknowledges receipt of a copy of such Terms
      and Conditions. Lessee further acknowledges and agrees to maintain payments
      hereunder through BillPayer 2000®
      throughout the term of this Lease.

     

    Tax,
      Interest and Security.

     

    For
      federal and state income tax purposes, Lessor and Lessee agree that Lessee
      will
      be considered the owner of the Equipment. Accordingly, Lessor agrees (i) not
      to
      take actions or positions inconsistent with Lessee as owner of the Equipment
      on
      or with respect to its federal income tax return, and (ii) not to claim any
      tax
      benefits available to an owner of the Equipment on or with respect to its
      federal or state income tax return. The foregoing undertakings by Lessor shall
      not be violated by Lessor’s taking a tax position inconsistent with the
      foregoing to the extent such position is required by law or to the extent such
      position is taken without gross negligence on the part of Lessor. Lessor shall
      in no event be liable to Lessee if Lessee fails to secure any of the tax
      benefits available to the owner of the Equipment. 

     

    Nothing
      contained in the Lease Documents shall require Lessee at any time to pay
      interest at a rate exceeding the maximum permissible rate under applicable
      law.
      To the extent that any Rent is characterized as interest and if such interest
      payable by Lessee on any date would exceed the maximum amount permitted by
      applicable law, such interest payment shall automatically be reduced to such
      maximum amount permitted. Any interest actually received for any period in
      excess of such maximum amount permitted for such period shall be held by Lessor
      as security for the obligations of Lessee under this Lease.

     

    To
      the
      extent permitted by applicable law, Lessee waives any rights now or hereafter
      conferred by statute or otherwise to recover incidental or consequential damages
      from Lessor for any breach or any other reason whatsoever. In order to secure
      the prompt payment of Rent under and with respect to this Lease, and the
      performance and observance by Lessee of all the agreements, covenants and
      provisions hereof (collectively, the “Obligations”), Lessee hereby grants to
      Lessor a first priority security interest in all of Lessee’s right, title and
      interest in the following (whether now existing or hereafter created and whether
      now owned or hereafter acquired): (i) the Equipment (including, without
      limitation, all inventory, equipment, fixtures or other property comprising
      the
      same), and general intangibles relating thereto, (ii) additions, attachments,
      accessories and accessions thereto whether or not furnished by the Supplier
      of
      such Equipment, (iii) all subleases (including the right to receive any payment
      thereunder and the right to make any election or determination or give any
      consent or waiver thereunder), chattel paper, accounts, security deposits and
      bills of sale relating thereto, (iv) any and all substitutions, replacements
      or
      exchanges for any such Equipment or other collateral, and (v) any and all
      products and proceeds of any collateral hereunder (including all insurance
      and
      requisition proceeds and all other payments of any kind with respect to the
      Equipment and other collateral in and against which a security interest is
      granted hereunder). Lessee agrees that with respect to the Equipment, in
      addition to all of the other rights and remedies available to Lessor hereunder
      upon the occurrence of an Event of Default, Lessor shall have all of the rights
      and remedies of a secured party under the Uniform Commercial Code. Lessee
      further agrees that the original principal amount of the obligations hereunder
      shall be an amount equal to Lessor’s Capitalized Cost, and that such principal
      amount shall accrue interest at the implicit interest rate reflecting Lessor’s
      financial assumptions at the time of the execution of the Lease (including
      any
      outstanding balance at the end of the Base Lease Term as reflected by the
      purchase price for the Equipment at the end of the Base Lease Term set forth
      in
      Section 0).
      Lessee
      hereby authorizes Lessor to file, solely at the expense of Lessee, any Uniform
      Commercial Code financing statements or other similar documents that Lessor
      reasonably deems necessary or advisable to protect its interest. Lessee agrees
      promptly to execute and deliver to Lessor such further documents or other
      assurances, and to take such further action, including obtaining landlord and
      mortgagee waivers, as Lessor may from time to time reasonably
      request.

    Insurance.
      

     

    The
      amount of public liability insurance including personal injury and property
      damage required to be maintained by Lessee pursuant to Section 10(a) of the

    End
      of Term.

    

    (h)  Upon
      the
      expiration of the Base Lease Term, so long as (i) no Default or Event of Default
      has occurred and is continuing and (ii) this Lease shall not have been earlier
      terminated, Lessee shall, upon the terms and conditions set forth below,
      purchase all but not less than all of the Equipment for a price equal to One
      Dollar ($1.00) plus all Rent then due and payable pursuant to this Lease and
      Taxes (including all sales and use Taxes) payable in connection with such
      purchase. Upon the purchase of the Equipment in accordance with the terms
      hereof, and payment of all other amounts then due and payable under this Lease,
      Lessor will deliver to Lessee a bill of sale transferring title to the Equipment
      to Lessee on an “as-is”, “where-is” basis without representation or warranty of
      any kind except that Lessor shall warrant that the Equipment is free, clear
      and
      unencumbered of all Liens arising by, through or under Lessor except for such
      Liens that Lessee is required to remove pursuant to the terms of the
      Lease.

     

    (i)  Except
      to
      the extent otherwise expressly set forth herein in case of a permitted
      prepayment in full of all Basic Rent and other obligations due under this Lease,
      the amount of Basic Rent or any other obligation required to be paid under
      this
      Lease shall not be discounted by virtue of the fact that such amount may be
      paid
      by the Lessee prior to the due date thereof.

     

    Amendments
      to Master Lease and Additional Lease Provisions.

     

    (j)  Section
      10(a) of the Master Lease is hereby amended by deleting the words “Stipulated
      Loss Value (as defined in the applicable Equipment Schedule) of such Equipment
      at any time” appearing therein and inserting in lieu thereof, the words,
“Lessor’s Capitalized Cost or such lesser amount to which Lessor shall
      reasonably consent.” 

     

    (k)  Section
      10(c) of the Master Lease is hereby amended by replacing the two references
      to
“Stipulated Loss Value” with the words “amounts due to Lessor pursuant to
      Section 11(b)(ii) following an Event of Loss.”

     

    (l)  Section
      11(b)(ii) of the Master Lease is hereby deleted in its entirety and the
      following is hereby inserted in lieu thereof: “(ii) pay to Lessor on the next
      succeeding Rent Payment Date (the “Loss Payment Date”) the sum of (A) all Rent
      due and owing hereunder with respect to such Item of Equipment (at the time
      of
      such payment) including all Basic Rent payable on such Rent Payment Date plus
      (B) an amount equal to each installment of Basic Rent payable under the Lease
      on
      each Rent Payment Date during the Term after the Loss Payment Date, in each
      case, discounted from the Rent Payment Date on which such payment would have
      been due to the Loss Payment Date at a rate per annum equal to the then current
      yield, as reasonably determined by Lessor, on United States Treasury securities
      with a remaining life to maturity equal to, or approximately equal to, the
      period from the Loss Payment Date to the final Rent Payment Date during the
      Term."

     

    
      
         

      

      
        16

        
          

        

      

      
         

      

    

    (m)  Section
      15 of the Master Lease is hereby amended by inserting the following immediately
      following clause (j) thereof: “(k) Upon the filing with the Secretary of State
      of Delaware
      of a
      Uniform Commercial Code financing statement describing Lessor, as secured party,
      Lessee, as debtor, and the Equipment as the collateral, Lessor shall have a
      first priority perfected security interest in the Equipment leased under this
      Lease.” 

     

    (n)  Section
      16(c) of the Master Lease is hereby deleted in its entirety and the following
      is
      hereby inserted in lieu thereof: “In addition to the foregoing, Lessee shall pay
      to Lessor on demand the sum of (i) any and all Rent which is then due or which
      has accrued to the date of demand and (ii) an amount equal to each installment
      of Basic Rent payable under the Lease on each Rent Payment Date during the
      Term
      after the date of demand, in each case, discounted from the Rent Payment Date
      on
      which such payment would have been due to the date of demand at a rate per
      annum
      equal to the then current yield, as reasonably determined by Lessor, on United
      States Treasury securities with a remaining life to maturity equal to, or
      approximately equal to, the period from the date of demand to the final Rent
      Payment Date during the Term. Lessor and Lessee agree that Lessor shall be
      entitled to such amount as damages for loss of bargain and not as a penalty
      and
      that such amount is reasonable in light of the anticipated harm to Lessor caused
      by an Event of Default.”

     

    (o)  Section
      19 of the Master Lease is hereby deleted in its entirety and the following
      is
      inserted, in lieu thereof: “19. [INTENTIONALLY OMITTED].”

     

    (p)  For
      purposes of this Equipment Schedule and to the extent required by law, Lessee
      for purposes of tangible personal property taxes will prepare and file
      applicable tax returns. Lessee hereby agrees to remit any tax due and owing
      (unless properly contested) directly to the taxing authority in which the
      Equipment is located. In the event the Lessee relocates the Equipment, Lessee
      shall notify Lessor. Upon request from Lessor, Lessee shall provide copies
      of
      any requested tax return and proof of payment. Both Lessor and Lessee agree
      to
      cooperate with each other to resolve any disputed assessment or governmental
      audit. Lessee shall have the right to contest any assessment provided such
      contest: (i) is properly initiated and challenged in accordance with such taxing
      jurisdiction’s procedures or is premised upon the advice of tax counsel; (ii)
      does not jeopardize the Equipment to confiscation or forfeiture; and (iii)
      does
      not subject Lessor to penalty or criminal sanction. Should any contest fail,
      or
      upon the advise of Lessor’s tax counsel be deemed to lack merit or be unlikely
      to succeed, Lessee shall upon demand from Lessor withdraw its challenge and
      promptly remit payment to the taxing authority.

     

    Except
      as
      expressly modified hereby, all terms and provisions of the Master Lease shall
      remain in full force and effect. This Equipment Schedule is not binding or
      effective with respect to the Master Lease or Equipment until executed on behalf
      of Lessor and Lessee by authorized representatives of Lessor and Lessee,
      respectively.
