     3. Broker: Reference is made to Article 1.01 D of the Lease. The parties
agree that said provision is hereby deleted and replaced with the following:

                       D. Broker: Julien J. Studley, Inc.

     4. Floor Space: The rentable Floor Space of the Demised Premises is 163,537
square feet. Article 1.01 L of the Lease shall be deemed amended accordingly.

     5. Guarantor: None. Article 1.01 M of the Lease is hereby deleted.

     6. Landlord's Work: Landlord shall not be required to perform any work in
and to the Demised Premises. Tenant shall accept the Demised Premises in "as is"
condition. Further, Landlord shall not be obligated to make any contribution or
allowance to Tenant in connection with any work or alterations which Tenant may
choose to perform to the Demised Premises.

     7. Option to Renew: Reference is made to Article 2.02 of the Lease. The
parties agree that said provision is hereby deleted and replaced with the
following:

     R2. Provided there is no event of default by Tenant beyond the expiration
of any applicable notice and cure period, if any, Tenant shall have one (1)
option to extend the Term of its lease of the Demised Premises, from the date
upon which this Lease would otherwise expire, for a period of five (5) years
(herein referred to as the "First Extended Period"), upon the following terms
and conditions:

          1. If Tenant elects to exercise said option, it shall do so by giving
     notice of such election to Landlord on or before the date which is one (1)
     year before the beginning of the First Extended Period. Tenant agrees that
     it shall have forever waived its right to exercise such option if it shall
     fail for any reason whatsoever to give such notice to Landlord by the time
     provided herein for the giving of such notice, whether such failure is
     inadvertent or intentional, time being of the essence as to the exercise of
     said option.

          2. If Tenant elects to exercise said option, the Term shall be
     automatically extended for the First Extended Period without execution of
     an extension or renewal lease. Within ten (10) days after request of either
     party following the effective exercise of such option, however, Landlord
     and Tenant shall execute, acknowledge and deliver to each other duplicate
     originals of an instrument in recordable form confirming that said option
     was effectively exercised.

          3. The First Extended Period shall be upon the same terms and
     conditions as are in effect immediately preceding the commencement of the
     First Extended Period; provided, however, that Tenant shall have no right
     or option to extend the Term for any period of time beyond the expiration
     of the First Extended Period and, provided further, that in the First
     Extended Period the Fixed Rent shall be as follows:

                                        2

<PAGE>

          The Fixed Rent during the First Extended Period shall be at a rate
          which is the greater of (i) $23.64 per rentable square foot of Floor
          Space per annum, or (ii) ninety-five percent (95%) of the then
          prevailing Fair Market Value ("FMV"). FMV shall be determined by
          mutual agreement of the parties. If the parties are unable to agree on
          the FMV within thirty (30) days of Tenant's exercise of its option,
          the parties shall choose a licensed Real Estate Appraiser who shall
          determine the FMV. The cost of said Real Estate Appraiser shall be
          borne equally by the parties. If the parties are unable to agree on a
          licensed Real Estate Appraiser within forty-five (45) days of Tenant's
          exercise of its option, each party shall select one Appraiser to
          appraise the FMV. All appraisals shall be rendered within thirty (30)
          days of appointment of the respective Appraiser appointed under this
          paragraph. If the FMV as determined by the Appraisers hired by Tenant
          and Landlord differ, then the Appraisers shall select a third licensed
          Real Estate Appraiser to determine FMV. Within fifteen (15) days of
          the appointment, the third Real Estate Appraiser shall determine the
          FMV by selecting the FMV of either of the Appraisers selected by
          Tenant and Landlord; the third Real Estate Appraiser's determination
          of FMV is limited to selecting the FMV of either Landlord's Appraiser
          or Tenant's Appraiser.

     8. Parking: Reference is made to Article 5.03 of the Lease. The parties
agree that the following sentences shall be inserted at the conclusion thereof:

          "Landlord shall not assess any parking charge upon Tenant in
          connection with Tenant's use of the parking facilities located on the
          Land." Notwithstanding anything to the contrary contained in the
          Lease, Tenant shall have the right to use all of the available parking
          spaces on the Land, and Landlord shall not have the right to reduce
          the available parking spaces on the Land without Tenant's prior
          consent, which consent may be withheld in Tenant's sole discretion.
          Further, notwithstanding anything contained in Article 17.03 to the
          contrary, Tenant's obligation as described therein with respect to the
          paved areas shall include, but not be limited to, all parking areas on
          the Land.

          "Landlord shall use reasonable efforts (provided same is at no cost to
          Landlord not reimbursed by Tenant) to accommodate Tenant's temporary
          increased parking needs during a disaster recovery situation."

     9. Operating Expenses/Real Estate Taxes: Reference is made to Article 6 of
the Lease. The parties agree that said Article 6 shall apply with respect to the
payment of Operating Expenses and Real Estate Taxes during the Extended Period.

     10. Subordination: Reference is made to Article 9 of the Lease. The parties
agree that Article 9 shall be supplemented as follows:

          Landlord shall deliver to Tenant, at Tenant's sole cost and expense
          (not including any legal fees incurred by Landlord for Landlord's role
          in connection with the procurement of any such SNDA), a subordination,
          non-disturbance and attornment Agreement ("SNDA") in commercially
          reasonable form acceptable to Landlord, Tenant and the party from
          which the SNDA is sought, from any existing or future Superior Lessor
          or Superior Mortgagee and Tenant's subordination of the Lease pursuant
          to Section 9.01 is expressly contingent upon and subject to a fully
          executed SNDA by Tenant, Landlord and any current Superior Lessor and
          Superior Mortgagee being in full force and effect during the Term.

     11. Assignment/Subletting: Reference is made to Article 11.01 of the Lease.
The following phrase shall be added at the conclusion of that provision:

          Landlord may not (i) withhold its consent to any assignment or
          subletting based on the identity of the proposed assignee or subtenant
          provided such proposed assignee or subtenant may not be an existing
          tenant of Landlord or its affiliates (in which case Landlord may
          withhold its consent) and further provided any such assignee or
          subtenant intends to and does use the Demised Premises for the
          Permitted Uses, or (ii) impose any restriction upon Tenant in
          connection with any proposed subletting as it relates to the minimum
          rents to be charged by Tenant in connection with any such subletting.
          In connection with any permitted assignment or sublet by Tenant,
          Tenant shall be entitled to retain any fees, charges or rent paid by
          the proposed assignee or subtenant, and Landlord shall have no claim
          or right to any such fees, rent or proceeds from such assignment or
          sublet.

<PAGE>

     Reference is made to Article 11.07 of the Lease. The parties agree that
said provision is hereby deleted. The following provision shall replace the
existing Article 11.07:

          Notwithstanding anything contained in this Lease to the contrary,
          Landlord shall not be obligated to entertain or consider any request
          by Tenant to consent to any proposed assignment of this Lease or
          sublet of all or any part of the Demised Premises unless each request
          by Tenant is accompanied by a non-refundable fee payable to Landlord
          in the amount of One Thousand Dollars ($1,000.00) to cover Landlord's
          administrative, legal, and other costs and expenses incurred in
          processing each of Tenant's requests. Neither Tenant's payment nor
          Landlord's acceptance of the foregoing fee shall be construed to
          impose any obligation whatsoever upon Landlord to consent to Tenant's
          request.

     12. Insurance: Reference is made to Article 13.02 of the Lease. The parties
hereby agree that following provision is added at the conclusion of Article
13.02:

          The certificates of insurance to be delivered to Landlord by Tenant
          shall name Landlord as an additional insured and, at Landlord's
          request, shall also name any Superior Lessors or Superior Mortgagees
          as additional insureds, and the following phrase must be typed on the
          certificate of insurance: "Hartz Mountain Industries, Inc., and its
          respective subsidiaries, affiliates, associates, joint ventures, and
          partnerships, are hereby named as additional insureds as their
          interests may appear (and if Landlord has so requested, Tenant shall
          include any Superior Lessors and Superior Mortgagees as additional
          insured(s)). It is intended for this insurance to be primary and
          non-contributing."

     13. Alterations: Reference is made to Article 15 of the Lease. The parties
agree that the following provisions shall be added to that Article of the Lease:

          15.03 Reference is made to Article 15.01 of the Lease. Landlord agrees
          that it shall not unreasonably withhold, delay or condition its
          consent to any alteration requested by Tenant. Notwithstanding
          anything contained in this Article 15 to the contrary, (i) Landlord's
          consent shall not be required with respect to those alterations
          requested

                                        5

          by Tenant which are (a) less than $100,000 in scope, and (b) do not
          materially and adversely affect the structure of the Building, and (c)
          do not materially and adversely affect the mechanical systems in the
          Building, provided, however, except for those purely cosmetic
          alterations, Tenant shall nonetheless provide Landlord with notice of
          all alterations; and (ii) regardless of whether an alteration is one
          which requires Landlord's consent or not, Tenant will be required to
          restore the Demised Premises to the condition existing before the
          alteration was implemented (and repair any resultant damage resulting
          therefrom) on or prior to the expiration of the Term, subject to
          reasonable wear and tear and damage by casualty and condemnation.

          15.04. Landlord shall not impose any fee for review and/or approval of
          plans and/or specifications for any alteration proposed by Tenant
          (inclusive of any "initial improvements" [performed by Tenant at the
          commencement of the Extended Period)]; (said initial improvements
          sometimes hereinafter referred to as the "Tenant's Work") other than
          actual and reasonable out of pocket costs incurred by Landlord.
          Further, and notwithstanding anything to the contrary contained in
          Article 15 of the Lease, Landlord shall not impose any fees upon
          Tenant related to Landlord's oversight of any Tenant's Work or
          alteration.

          15.05. Notwithstanding anything to the contrary contained in the
          Lease, Tenant reserves the right, without Landlord's consent but on
          notice to Landlord, to designate a general contractor of its choosing
          to perform Tenant's Work and/or alterations in and to the Demised
          Premises. Landlord shall not be entitled to any fees for supervision
          or otherwise if Tenant chooses a third party general contractor in
          accordance with the preceding sentence. In the event Landlord elects
          to utilize Landlord's services to perform Tenant's Work or
          alterations, Landlord shall solicit competitive bids from at least
          three (3) third party subcontractors and Tenant shall have the right
          to review said bids. Tenant shall retain the right to designate
          specific contractors from those providing bids to Landlord.
