     3.2. RENEWAL OPTION. Lessee shall, provided the Lease is in full force and
     effect and Lessee is not in default under any of the other terms and
     conditions of the Lease at the time of notification or commencement, have
     one (1) successive option to renew this Lease for a term of five (5) years,
     for the portion of the leased premises being leased by Lessee as of the
     date the renewal term is to commence, on the same terms and conditions set
     forth in the Lease, except as modified by the terms, covenants and
     conditions as set forth below:

               (a) If Lessee elects to exercise said option, then Lessee shall
          provide Lessor with written notice no earlier than the date which is
          360 days prior to the expiration of the then current term of the Lease
          but no later than the date which is 120 days prior to the expiration
          of the current term of the Lease, and the Annual Rent and Monthly
          Installment in effect at the expiration of the then current term of
          the Lease shall he increased, commencing oil the first day of the new
          renewal term, to reflect the adjusted rental rate as calculated below.
          If Lessee falls to provide such notice, Lessee shall have no further
          or additional right to extend or renew the term of the Lease. The
          notice shall be given in the manner provided in the Lease for the
          giving of notices to Lessor.

               (b) The option period rental rate ("Adjusted Rental Rate") shall
          be the first year rental rate of $43,657.00 multiplied times 95* of
          the factor which has as its denominator the CPI Index (Los

          September, 1992 and has as its numerator the Index for September,
          2002. The Adjusted Rental Rate will be increased three and one-half
          (3.5%) percent per annum in Years 2-5 of the option term. In no event
          shall the Adjusted Rental Rate be less than the rental rate in effect
          at the expiration of the initial lease term.

               (c) This option is not transferable; the parties hereto
          acknowledge and agree that they intend that the aforesaid option to
          renew this Lease shall be "personal" to Lessee as set forth above and
          that in no event will any assignee or sublessee have any rights to
          exercise the aforesaid option to renew.

5.   Section 6.1 of the Lease entitled Use is deleted in its entirety and 
replaced with the following:

     6.1 USE. The leased premises shall be used and occupied only for
     manufacturing, warehousing and distributing electronic parts and for
     related administrative offices or any other use, which is reasonably
     comparable, and for no other purpose. Lessee shall comply


                                          2


     with all governmental laws, ordinances and regulations applicable to the 
     use of the leased premises and its occupancy and shall promptly comply with
     all governmental orders and direction for the correction, prevention and 
     abatement of any violations in or upon, or in connection with, the leased 
     premises, all at Lessee's sole cost and expense. Lessee shall not use nor 
     permit the use of the leased premises in any manner that will tend to 
     create waste or a nuisance.

6.   HAZARDOUS MATERIALS.

     (a)  Lessee agrees that Lessee, its agents and contractors, licensees, or
     invitees shall not handle, use, manufacture, store or dispose of any
     flammables, explosives, radioactive materials, hazardous wastes or
     materials, petroleum products or derivatives (collectively "Hazardous
     Materials") on, under, or about the leased premises, except in compliance
     with all laws relating to any Hazardous Materials so brought or used or
     kept in or about the leased premises. Annually during t1je lease term,
     Lessee shall provide Lessor with a written list of Hazardous Materials used
     in connection with its manufacturing operations on the leased premises.

     (b)  Lessee shall secure and comply with all permits necessary for Lessee's
     operations on the leased premises. Lessee shall give or post all notices
     required by all applicable laws pertaining to Hazardous Materials. If
     Lessee shall at any time fail to comply with this Paragraph, Lessee shall
     promptly notify Lessor in writing of such noncompliance.

     (c) Lessee shall not store Hazardous Materials on the premises for more
     than 90 days unless such storage is in compliance with applicable laws;
     "hazardous waste" has the meaning given it by the Resource Conservation and
     Recovery Act of 1976, as amended. Lessee and Lessor acknowledge there is an
     existing 550-gallon single-walled underground diesel fuel tank, which shall
     be operated in compliance with all applicable laws. Lessee shall not
     install any other underground storage tanks on the leased premises, and any
     above ground storage tanks shall be operated in compliance with law
     including without limitation any double-containment requirements. Lessee
     shall not dispose of any Hazardous Materials on the leased premises. In
     performing any alterations of the leased premises permitted by the Lease,
     Lessee shall not install any Hazardous Material in the leased premises
     without the specific consent of Lessor attached as an exhibit to this Rider
     which consent shall not be unreasonably withheld.

     (d) Any increase in the premiums for necessary insurance on the Property,
     which arises from Lessee's use, and/or storage of Hazardous Materials shall
     be solely at Lessee's expense. Lessee shall procure and maintain at its
     sole expense such additional insurance as may be necessary to comply with
     any requirement of any Federal, State or local governmental agency with
     jurisdiction.

     (e) If Lessor, in its sole discretion, reasonably believes that the leased
     premises have become contaminated with Hazardous Materials that must be
     removed under the laws of the state where the leased premises are located,
     as a result of a breach by Lessee under the provisions of this Lease,
     Lessor, in addition to its other rights under this Lease, may enter


                                          3


     upon the leased premises and obtain samples from the leased premises,
     including without limitation the soil and groundwater under the leased
     premises, for the purposes of analyzing the same to determine whether and
     to what extent the leased premises have become so contaminated provided,
     however, that such action shall not unreasonably disrupt the Lessee's
     operations at the premises. If such testing discloses that, there exists
     contamination for which Lessee is liable under the Lease, and if Lessee
     refused Lessor's prior request to conduct such testing, then Lessee shall
     reimburse Lessor for its reasonable costs of such testing. Lessee may not
     perform any sampling, testing, or drilling to locate any Hazardous
     Materials on the leased premises without Lessor's prior written consent
     unless Lessee is required by law, rule or order.

     (f) Without limiting the above, Lessee shall reimburse, defend, indemnify
     and hold Lessor harmless from and against any and all claims, losses,
     liabilities, damages, costs and expenses, including without limitation,
     loss of rental income, loss due to business interruption, and attorneys
     fees and costs, arising out of or in any way connected with the use,
     manufacture, storage, or disposal of Hazardous Materials by Lessee, its
     agents or contractors on, under or about the leased Premises including,
     without limitation, the costs of any required or necessary investigation,
     repair, cleanup or detoxification and the preparation of any closure or
     other required plans in connection herewith, whether voluntary or compelled
     by governmental authority. The indemnity obligation of Lessee under this
     clause shall survive any termination of the Lease. Lessee shall perform any
     required or necessary investigation, repair, cleanup, or detoxification of
     the leased premises. In such case, Lessor shall have the right to approve
     all plans and consultants, provided the Lessor's approval rights shall not
     supersede any government regulations. Lessee shall provide Lessor on a
     timely basis with (I) copies of all documents, reports, and communications
     with governmental authorities; and (ii) notice and an opportunity to attend
     all meetings with regulatory authorities. Lessee shall comply with all
     notice requirements and Lessor and Lessee agree to cooperate with
     governmental authorities seeking access to the leased premises for purposes
     of sampling or inspection. No disturbance of Lessee's use of the leased
     premises resulting from activities conducted pursuant to this Paragraph
     shall constitute an actual or constructive eviction of Lessee from the
     leased premises.

     (g)  Notwithstanding anything set forth in this Lease, Lessee shall only be
     responsible for contamination of Hazardous Materials or any cleanup
     resulting directly therefrom, resulting directly from matters occurring or
     Hazardous Materials deposited by Lessee (or by contractors, invitees,
     agents or representatives of Lessee) during the Lease term, and any other
     period of time during which Lessee is in actual or constructive occupancy
     of the leased premises. Lessee shall take reasonable precautions to prevent
     the contamination of the Premise with Hazardous Materials by third parties.

     (h) It shall not be unreasonable for Lessor to withhold its consent to any
     proposed assignment or sublease if (i) the proposed assignee's or
     sublessee's anticipated use of the leased premises involves the generation,
     storage, use, treatment or disposal of Hazardous Materials; in a materially
     different manner or magnitude as Lessee's (ii) the proposed


                                          4


     assignee or sublessee has been required by any prior landlord, lender, or
     governmental authority to take remedial action in connection with Hazardous
     Materials contaminating a property if the contamination resulted from such
     assignee's or sublessee's actions or use of the property in question; or
     (iii) the proposed assignee or sublessee is subject to an enforcement order
     issued by any governmental authority in connection with the use, disposal
     or storage of a Hazardous Material; and with respect to clauses (ii) and
     (iii) , that the circumstances giving rise to such requirement of remedial
     action or such enforcement order and Assignee's response thereto reasonably
     and adversely reflect upon Assignee's capacity to conduct its operations on
     the leased premises in a responsible manner so as to reasonably ensure that
     no such remedial action is required or order is issued with respect to
     Assignee's activities on the leased premises, or if such remedial action is
     required or order is issued, that Assignee will respond thereto in a
     responsible manner.

     (i) If any of Lessee's insurance insures against claims of the type dealt
     with in this Rider shall be considered primary coverage for claims against
     the Property arising out of or under this paragraph.

     (j)  In the event of (i) any transfer of Lessee's interest under this
     Lease; or (ii) the termination of this Lease, by lapse of time or
     otherwise, Lessee shall be solely responsible for compliance with any and
     all then effective federal, state or local laws concerning the presence of
     Hazardous Materials in or on the leased premises, Building, or Property
     (for example, the New Jersey Environmental Cleanup Responsibility Act, the
     Illinois Responsible Property Transfer Act, or similar applicable state
     laws), including but not limited to any reporting or filing requirements
     imposed by such laws.

All consents given by Lessor pursuant to this Rider shall be in writing and
shall be attached as amendments to this  Rider

     all of the provisions of this Lease, unless this Lease is otherwise
     terminated pursuant to its terms. If any mortgagee, trustee or ground
     lessor shall elect to have this Lease prior to the lien of its mortgage,
     deed of trust or ground lease, and shall give written notice thereof to
     Lessee, this Lease shall be deemed prior to such mortgage, deed of trust or
     ground lease, whether this Lease is dated prior or subsequent to the date
     of said mortgage, deed of trust or ground lease or the. date of recording
     thereof. Lessor agrees, upon request by Lessee, to use best efforts to
     obtain a commercially reasonable non-disturbance agreement from any such
     mortgagee beneficiary of a deed of trust or lessor of Lessor. Lessee agrees
     to execute any documents not inconsistent with this Lease required to
     effectuate such subordination or to make this Lease prior to the lien of
     any ground lease, mortgage or written deed of trust, as the case may be,
     within tell (10) days after written demand. Failure of Lessee to execute
     any statements or instruments necessary or desirable to effectuate this
     Section 22.15 with-in ten (10) days after written request by Lessor to do
     so shall constitute a material default under this Lease.

     In the event any Proceedings are brought for foreclosure, or in the event
     of the exercise of the Power of sale under any mortgage or deed of trust
     made by Lessor covering the leased premises, or should the lease in which
     Lessor is the lessee be terminated, Lessee shall attorn to the Purchaser or
     lessor under such lease upon any foreclosure, sale or lease termination and
     recognize the purchaser or lessor as Lessor under this Lease, provided that
     the purchaser or lessor shall acquire and accept the leased premises
     subject to this Lease. Upon failure by Lessee to execute any statements or
     instruments necessary or desirable to effect the foregoing provisions of
     this Section 22.15 within ten (10) days after written request to do so by
     Lessor, in addition to any other rights or remedies of Lessor hereunder,
     Lessee hereby irrevocably appoints Lessor as its attorney-in-fact with the
     full power and authority to execute and deliver in the name of Lessee any
     of the statements or instruments set forth in this Section 22.15.

15.  Section 24 of the Lease entitled Right of First Refusal is deleted in its
entirety and replaced with the following:

     24. RIGHT OF FIRST REFUSAL. Notwithstanding any other provision of the
     Lease to the contrary, Lessee shall have no right to exercise its Right of
     First Refusal, and Lessee's exercise of said Right of First Refusal may be
     nullified by Lessor and deemed of no further force or effect whatsoever, if
     Lessee shall be in default of any monetary obligation or material
     non-monetary obligation under the terms of the Lease (or would be in such
     default under the Lease but for the passage of time or giving of notice, or
     both) as of the date that Lessor first notifies Lessee in writing of the
     price and/or terms on which Lessor will Transfer the leased premises. If
     Lessor desires to exchange, sell, ground lease, option or otherwise
     transfer, excluding encumbrances, ("Transfer") or agree to Transfer all or
     any part of the leased premises, Lessor shall first notify Lessee in
     writing of the price and/or terms on which Lessor will Transfer. If Lessee,
     within fifteen (15) business days after Lessor's notice has been delivered
     indicates in writing its agreement to acquire the leased premises, on the
     terms stated in Lessor's notice, Lessor shall Transfer the leased premises
     to Lessee for the price and/or on the terms stated in Lessors notice,
     except that


                                          9


     in the event of an exchange, Lessee may elect to pay Lessor the equity
     value of Lessor's leased premises rather than exchange for "like kind"
     property; provided that Lessee will reasonably cooperate with Lessor in any
     exchange if it is at no added cost or expense to Lessee. If Lessee does not
     indicate its agreement in writing within said fifteen (15) business days;
     Lessor shall have the right to Transfer the leased premises to any
     purchaser, tenant or on the same terms as stated in the notice. In the
     event of a proposed Transfer of the leased premises, if Lessor does not
     enter into a binding contract and escrow to Transfer within six (6) months
     from the date Lessor's notice is delivered to Lessee, or in any event, if
     Lessor does not actually Transfer the leased premises within nine (9)
     months after Lessor's notice is delivered to Lessee, any further
     transaction shall be deemed a new determination by Lessor to Transfer the
     leased premises and the Provisions of this right of first refusal shall be
     applicable. If Lessor receives an offer with respect to a Transfer of the
     leased premises with-in said six (6) month period which is on price or
     financial terms different from those set forth in Lessor's notice to
     Lessee, before accepting such offer, Lessor shall first notify Lessee in
     writing of the terms of the offer. If Lessee, within fifteen (15) business
     days after Lessor's notice of such different terms has been delivered,
     indicates in writing its agreement to accept the transfer of the leased
     premises, Lessor shall Transfer the leased premises to Lessee for the price
     and on the terms stated in the notice. If Lessee does not indicate its
     agreement within said fifteen (15) business days, Lessor shall have the
     r1qht to Transfer the leased premises to the Purchaser on the terms of the
     notice Provided such Transfer is completed within the nine (9) month period
     mentioned above.

     This Right of First Refusal is not transferable; the parties hereto
     acknowledge and agree that they intend that the aforesaid Right of First
     Refusal to purchase the leased premises shall be "Personal" to Lessee as
     set forth above and that in no event will any assignee or sublessee have
     any rights to exercise the aforesaid Right of First Refusal.
