cost of designing and constructing the demising walls, such other Base Building
Improvements necessary to construct the UPS Equipment Room and a separate
electrical meter for such Space.

                                    RECITALS

     WHEREAS, Landlord and Tenant entered into that certain Lease dated June 1,

     WHEREAS, Landlord and Tenant further desire to amend the terms and
conditions of the Lease pertaining to the manner in which the Technical Space
Tenant Improvements and certain related improvements are to be constructed.

     NOW, THEREFORE, in consideration of the foregoing Recitals and the mutual
engagements of the parties hereto, it is agreed as follows:

     1. PERMITTED PURPOSE. Paragraph 1.1.11 of the Lease is hereby amended in
its entirety to read as follows:

        Permitted Purpose means that Tenant may use the Leased Premises for
        general office use and any lawful purpose incidental thereto, and may

        incidental thereto.

     2. TENANT'S SQUARE FOOTAGE. Paragraph 1.1.4 of the Lease is hereby amended
to provide that Tenant's Square Footage for the Leased Premises, as amended by

EXHIBIT A attached hereto, to be effective October 1, 1999 as set forth in
EXHIBIT A.

     4. TENANT'S PRO RATA SHARE. Paragraph 1.1.8 of the Lease is hereby amended

have the Technical Space Tenant Improvements constructed by a contractor other
than Lankford & Associates, Inc. under the supervision of Tenant's construction
manager, Aspen Engineering and Construction Management Services, Inc. ("Aspen").
If Tenant shall elect not to construct the Technical Space Tenant Improvements

improvements in place thereof, and the original Work Letter Agreement of the
Lease shall govern. The construction of the Technical Space Tenant Improvements
by Tenant shall be subject to the following additional terms and conditions:

        a. Tenant shall cause the Technical Space Tenant Improvements to be
designed and constructed in compliance with all of the terms and conditions of
the Lease, including, without limitation, paragraphs 6.1.5 and 6.1.6 of the
Lease. Lankford & Associates, Inc. shall act as the

<PAGE>   2

authorized agent and representative of Landlord in connection with the granting
of all approvals required to be given by Landlord of the Technical Space Tenant
Improvements on behalf of Landlord. Gary Eikenhorst shall act as the designated
representative of Lankford & Associates, Inc., and any agent or representative
as may be designated, assigned and referenced by written notice to Landlord from
Tenant shall act as the designated representative of Tenant.

        b. Tenant shall be responsible for, and shall pay when due, whether
incurred before, on, or after the effective date of this Second Amendment, any
fees or other compensation payable to Aspen, the contractors, suppliers, and
consultants providing services and materials relating to the design and
construction of the Technical Space Tenant Improvements. Landlord hereby
assigns to Tenant end Tenant hereby assumes and agrees to be responsible for and
pay all fees (including any and all amounts which have been billed to Landlord
or Lankford & Associates, Inc. but as of the effective date of this Second
Amendment are unpaid in the amount of Eighteen Thousand Four Hundred Ninety-Five
Dollars and Sixteen Cents ($18,495.16) (including Permit Fees reimbursement
amount)), and as set forth in the full and complete statement of all costs
associated in transferring the work attached hereto as EXHIBIT B and
incorporated herein by this reference, arising from: (1) the architectural
design services contract dated January 25, 1999, as amended by letter dated
April 12, 1999, between Landlord's Architect and Lankford & Associates, Inc.
pertaining to the design of the Technical Space Tenant Improvements, copies of
which are attached hereto as EXHIBIT C and incorporated herein by this
reference, and (2) the purchase order evidenced by a Quotation from Golesh Door
& Trim, Inc. dated April 19, 1999, and Invoice dated July 27, 1999, copies of
which are attached hereto as EXHIBIT D and incorporated herein by this
reference, for twenty-four (24) wooden doors for use in connection with
construction of the Technical Space Tenant Improvements (collectively, the
"Contracts"). In addition, Landlord hereby assigns to Tenant and Tenant hereby
assumes all rights and obligations under any and all permits, including without
limitation fire and building permits, arising out of, related to, or issued for
construction or installation of the Technical Space Tenant Improvements, whether
currently issued to Landlord, Lankford & Associates, Inc., or otherwise (the
"Permits"). Tenant shall indemnify, defend and hold harmless Landlord and
Lankford & Associates, Inc. from and against any and all claims, loss or damage,
including attorneys fees and expenses of Landlord or Lankford & Associates,
Inc., arising out of or related to the Contracts or the Permits from and after
the date hereof, and Tenant shall reimburse Landlord and Lankford & Associates,
Inc. for any costs of any Permits already issued, copies of which are attached
hereto as EXHIBIT E.

        c. In consideration of the change in the scope of work to be performed
by Landlord in connection with the design and construction of the Technical
Space Tenant Improvements, the amount of the available Landlord's Share (which
includes the Six Dollars ($6.00) per rentable square foot elected by Tenant
pursuant to paragraph 3 hereof) to be paid by Landlord for the cost of the
design and construction of the Technical Space Tenant Improvements shall be
reduced by Sixty-Two Thousand Five Hundred Dollars ($62,500.00). The amount of
available Landlord's share as of January 30, 1999, was Four Hundred Thirty-Two
Thousand One Hundred Eighty-Four Dollars ($432,184.00). Such amount was reduced
by Sixty-Nine Thousand Six Hundred Seven Dollars and Ninety-Nine Cents
(69,607.99) for payments made subsequent to January 30, 1999, to Landlord's
Architect and related to the Technical Space Tenant Improvements. Therefore, the
available amount of Landlord's Share, as reduced by the dollar amounts
specified above, is Three Hundred Thousand Seventy-Six Dollars and One Cent
($300,076.01) as of the effective date of this Second Amendment.

        d. Tenant shall be entitled to receive payment of Landlord's Share in
accordance with the following terms and conditions:

           i.  Tenant shall submit a written application no more frequently than
once each calendar month to the Landlord for payment of Landlord's Share
specifying by name and amount the parties to whom Tenant is currently obligated
for labor and materials in place and directly related to the construction of the
Technical Space Tenant Improvements accompanied by such schedules, affidavits,
leases, waivers, statements, invoices, bills, and other documents as Landlord
may reasonably request ("Application for Landlord's Share").

           ii. An Application for Landlord's Share shall be accompanied by:

               (1) A direct construction cost breakdown and request for partial
     payment in the form of the Application and Certificate for Payment (AIA
     Document G702 and G703), currently dated and executed by the general
     contractor and architect.

               (2) Such other invoices, receipts, bills, bills of sale, and
     statements as may be reasonably required by the Landlord to substantiate
     the amount requested and the appropriateness of the Application for
     Landlord's Share;

               (3) Unconditional waivers of liens from each contractor and
     subcontractor who has done work or furnished materials for construction
     of the Technical

                                      -2-

<PAGE>   3

     Space Tenant Improvements effective through the date of the immediately
     preceding payment on account of an Application for Landlord's Share in form
     satisfactory to Landlord;

               (4) A waiver of lien from any general contractor for all work,
     materials and services covered by the currently requested Application for
     Landlord's Share conditioned only upon payment of the Application for
     Landlord's Share in a form satisfactory to Landlord;

               (5) Evidence that any required inspections and approvals by any
     governmental authority or other political subdivision, agency, or
     instrumentality exercising jurisdiction over the Project have been
     satisfactorily completed or granted as the case may be.

           iii. Under no circumstances shall Landlord be required to make
payment of an item on an Application for Landlord's Share if Landlord believes
that: the work has not been completed; the work has not been completed in a
workmanlike manner; the work has not been completed in accordance with the
Construction Documents as submitted to and approved by Landlord; Landlord's
Lender (currently U.S. Bank National Association) withholds approvals necessary
for Landlord to make payments on an Application for Landlord's Share; or any of
the terms, conditions or approvals required under the Lease and the schedules
thereto, the First Amendment or this Second Amendment have not been complied
with.

           iv. At Landlord's discretion, Landlord may withhold ten percent (10%)
of the amounts requested on an Application for Landlord's Share. Upon one
hundred percent (100%) completion of the Technical Space Tenant Improvements,
Tenant may request that Landlord make payments on amounts previously withheld.

           v. The proceeds of any payment on an Application for Landlord's Share
shall be disbursed by Landlord to Tenant, on or before the last day of the
second full month following the date of receipt by the Landlord of the
Application for Landlord's Share, directly to Tenant by depositing such proceeds
as directed by the Tenant; provided, however, that such proceeds may be
disbursed at Landlord's option directly to the third parties or jointly to
Tenant and such third parties identified in the Application for Landlord's Share
entitled to receive such funds.

           vi. Once Landlord has paid Landlord's Share on account of payments on
Applications for Landlord's Share or otherwise, Landlord shall not be required
to make any further payments on an Application for Landlord's Share or any
portion thereof as the case may be.

           vii. No payment made on account of an Application for Landlord's
Share shall constitute a waiver of any condition precedent to the obligation of
Landlord to make any further payment on such Application for Landlord's Share or
preclude Landlord from thereafter declaring the failure of Tenant to satisfy
such condition precedent to be a default if such failure is not timely cured
after written notice and demand for the performance of such condition precedent
is delivered by Landlord to Tenant, nor shall any express or implied waiver on a
particular Application for Landlord's Share constitute a waiver of any condition
precedent to payment on account of any future Application for Landlord's Share.

           viii. Tenant shall have the right to review, and shall cooperate
fully with Landlord in meeting, any request made by Landlord's Lender, as it
applies to submission of documents for reimbursement of Tenant Improvement
Costs, which constitute conditions precedent to Landlord's ability to make
payments on account of an Application for Landlord's Share.

        e. Tenant shall, at Tenant's expense, maintain or cause, in the case of
any contractors or subcontractors, to be maintained in force and effect on the
Project at all times during the construction of the Technical Space Tenant
Improvements: all-risk builder's risk insurance in an amount equal to one
hundred percent (100%) of the replacement cost of the Technical Space Tenant
Improvements, providing all risk coverage on the Technical Space Tenant
Improvements and materials stored on the property and elsewhere and including
the perils of collapse, water damage, business interruption, boiler/machinery
coverage, permission to occupy, interest costs and other risks typically insured
under such type of policy; and commercial, general liability insurance for
Tenant and Tenant's contractors and subcontractors including blanket contractual
liability, products and completed operations, personal injury (including
employees), independent contractors, explosion, collapse, and other risks
typically insured under such type of policy.

        f. The demising wall and door creating the UPS Equipment Room on the
first floor of the Building shall be constructed by Landlord. Tenant shall be
responsible for the design, construction and installation of the Interior of the
UPS Equipment Room as part of the Technical Space Tenant Improvements.

     6. ANTENNAE INSTALLATION. Paragraph 8 of the Addendum to Lease set forth as
Schedule 9 of the Lease is hereby amended to provide that Landlord shall be
responsible for taking all reasonable steps necessary to apply for the approval
of the architectural control committee having jurisdiction over the Project for
the location and design of the Antennae Equipment to be installed by Tenant in
accordance with such paragraph 8, at no additional cost to Tenant.

     7. EMERGENCY GENERATOR. Paragraph 9 of the Addendum to Lease set forth as
Schedule 9 of the Lease is hereby amended as follows. The Generator Equipment
desired to be utilized by Tenant cannot reasonably be accommodated within the
Generator Pad Premises originally contemplated by the terms and conditions of
paragraph 9 of the Addendum to Lease. Therefore, subject to the availability of
the Approvals defined in paragraph 9.e of the Addendum to Lease, Landlord
shall make available to Tenant an alternative location for a generator pad on
the second level of the parking structure of the Project in the location more
particularly set forth on the floor plan of the parking structure attached
hereto as EXHIBIT F and incorporated herein by this reference (the "Alternative
Generator Pad Premises"). Landlord shall be responsible for applying for all
necessary Approvals for, and for the design and construction of the Alternative
Generator Pad Premises, including the construction of any alterations to the
Project parking structure that may be necessary or desirable to maintain the
structural integrity of such structure and to satisfy any reasonable
requirements imposed by applicable covenants governing the Project. All such
work to be performed by Landlord shall be performed in accordance with the Work
Letter Agreement, at the sole cost and expense of Tenant; provided, however,
Landlord shall be responsible for taking all reasonable steps necessary to apply
for the approval of the architectural control committee having jurisdiction over
the Project for the location and design of the Alternative Generator Pad
Premises at no additional cost to Tenant. The remainder of such paragraph 9
shall remain in full force and effect.

     8. NO CLAIMS. Landlord and Tenant hereby acknowledge and agree that all
matters relating to the design and construction of the Building, and Base Tenant
Improvements within the Building and the Leased Premises are consistent and
comply with all applicable permits and codes governing the construction and
operation of the Building and the Leased Premises and such improvements are
completed and acceptable to both such parties.

     9. CONTINUING RIGHT OF FIRST REFUSAL. Tenant acknowledges that Landlord
desires and intends to enter into one or more leases for space located on the
third floor of the Building, which is currently subject to a Continuing Right of
First Refusal held by Tenant as set forth in paragraph 2 of the Addendum to
Lease set forth as Schedule 9 of the Lease. Tenant hereby waives and releases
its Continuing Right of First Refusal as it applies to the third floor of the
Building for a period of eighteen (18) months from end after the date of this
Second Amendment.

     10. LEGAL FEES. Upon execution of this Second Amendment, Tenant has
delivered to Landlord the sum of One Thousand Dollars ($1,000.00) as a
reimbursement of a portion of the legal fees incurred by Landlord in connection
with the preparation of this Second Amendment.

     11. LEGAL EFFECT. Capitalized terms shall have the meanings set forth
herein or in the Lease and the First Amendment. To the extent the terms and
conditions of the Lease and the First Amendment are inconsistent with this
Second Amendment, the terms and conditions of this Second Amendment shall apply.
In all other respects, the terms and conditions of the Lease and the First
Amendment, except as amended by this Second Amendment, are and shall remain in
full force and effect, and the terms and conditions of the Lease and the First
Amendment are hereby incorporated by this reference.
