(b)Section 3.2 of the Lease shall be revised in its entirety to read as follows:

3.2 Additional Rental. In addition to the Total Monthly Rental, Tenant agrees to
pay to Landlord as additional rent ("Additional Rental) an amount equal to the
Operating Expenses (as hereinafter defined) for each calendar year during the
term of this Lease. Tenant's liability for Additional Rental for any partial
year during the term of this Lease shall be prorated based upon the ratio of the
number of days within the term of this Lease for the partial year as compared to
the total number of calendar days in such year.

A. Operating Expenses: For the purposes of determining Additional Rental,
"Operating Expenses" shall mean the following costs and expenses paid or
incurred by Landlord in connection with the Project for a particular calendar
year or portion thereof, as determined by Landlord: all ad valorem taxes and
other real estate taxes and all special assessments


<PAGE>   3


(provided, however, that if pursuant to the authorizing legislation or the
taxing authority's requirements, Landlord shall have the right to elect to
either make a lump sum payment or cause such tax or assessments to be amortized
and paid over a period of years, such taxes and assessments for purposes of
computing Operating Expenses shall be amortized over the longest period of time
permitted by such authorizing legislation or requirements of the taxing
authority for the payment of such taxes or assessments); costs and expenses of
contesting the validity or amount of real estate taxes; and insurance premiums.

B. Monthly Payment of Estimated Additional Rental: The Operating Expenses for
each calendar year shall be estimated by Landlord, and written notice thereof
shall be given to Tenant. Upon receipt of said written notice from Landlord, the
estimated Additional Rental shall be due and payable as herein provided. Tenant
agrees to pay Landlord each month, at the same time the Total Monthly Rental is
due, an amount equal to one-twelfth (1/12) of the estimated annual Additional
Rental due for such year.

C. Revisions of Estimated Additional Rental: If real estate taxes, or any
portion of Operating Expenses increase during a calendar year, Landlord may
revise the estimated Additional Rental during such year by giving Tenant written
notice to that effect, and thereafter Tenant agrees to pay Landlord, in each of
the remaining months of such year, an additional amount equal to the amount of
such annual increase in the estimated Additional Rental divided by the number of
months remaining in such year.

D. Annual Adjustment of Additional Rental: After the end of each calendar year,
Landlord shall prepare and deliver to Tenant a statement showing Tenant's total
amount of Additional Rental. Within thirty (30) days after receipt of the
aforementioned statement, Tenant agrees to pay Landlord, or if Tenant has
overpaid, Landlord shall credit against the next Additional Rental payment or
payments due from Tenant, as the case may be, the difference between Tenant's
actual Additional Rental due for the preceding calendar year and the estimated
Additional Rental paid by Tenant during such year.

4. Maintenance. Section 7.1(i) shall be amended by the addition of the following
language at the end thereof:

Notwithstanding the foregoing, Landlord shall have the option to require Tenant
to maintain the electrical, mechanical (including HVAC) and plumbing systems
servicing the Premises or any part thereof, in which event Landlord shall
reimburse Tenant for the reasonable costs of such maintenance.

5. Tenant Improvement Allowance. (a) Landlord agrees to reimburse Tenant for
one-half of the costs of alterations, improvements, modifications or additions
to the Premises made by Tenant up to a total maximum payment by Landlord of
$10,000.00, provided that all such alterations, improvements, modifications and
additions have been consented to by Landlord pursuant to Section 9.1 of the
Lease and have been performed by a contractor approved by

Landlord. Such reimbursement shall be made within ten (10) day after Tenant
presents Landlord with proof reasonably satisfactory to Landlord of the payment
of such amount.

(b) Tenant agrees to pay Landlord, in addition to all other amounts due
hereunder, the amount of $300.00 per month on the first day of each month
beginning July 1, 1998, and continuing through and including April 1, 2001.

6. Renewal Option. The parties acknowledge that Tenant has exercised the Option
set forth in Section 2.3 of the Lease. So long as Tenant is not then in default,
Tenant shall have another option (the "Second Option") to renew this Lease (but
only as to that portion of the Premises not subleased to GTE Intelligent Network
Services Incorporated ("GTE"), in the event and only in the event GTE exercises
its option to lease its subleased space directly from Landlord) for a five (5)
year term, beginning on the expiration of the Term of this Lease as extended in
Paragraph 1 above, and continuing for five (5) years thereafter, by notifying
Landlord in writing of its election at least nine (9) months prior to the end of
such Term of this Lease. Such renewal shall be on all of the terms and
conditions of this Lease in effect in the last month of the extended term of
this Lease which are not inconsistent herewith, except that the Total Monthly
Rental shall be at a market rental rate as determined by Landlord in its
reasonable judgment. Landlord shall give written notice (the "Rental Notice") to
Tenant of the Total Monthly Rental to be in effect during such renewal term
within thirty (30) days after receipt of Tenant's notice exercising the Second
Option, and Tenant shall have a right during the thirty (30) day period after
receipt of the Rental Notice within which to revoke the exercise of the Second
Option by giving written notice of revocation to Landlord within such thirty
(30) day period, in which event the Term of this Lease shall expire on May 31,
2008. If Tenant does not revoke its exercise of the Second Option within such
thirty (30) day period, then the Total Monthly Rental specified by Landlord the
Rental Notice shall be in effect during such renewal period.

7. Tenant's Insurance. The minimum levels of insurance required to be maintained
by Tenant pursuant to Section 8.3 of the Lease are as follows:

Bodily injury or death     -     $1,000,000.00
Property damage            -     $1,000,000.00

8. Defined Terms. All capitalized terms used herein shall have the meaning
ascribed in the Lease, unless a different meaning is given herein.

EXCEPT as expressly modified herein, the terms of the Lease shall remain in full
force and effect and Landlord and Tenant hereby ratify such terms, as herein
amended.

EXECUTED effective as of the 27 day of July 1998.
