<PAGE>

     controversy arising from or connected with any of the foregoing in
     accordance with the Credit Agreement.

Capitalized terms used in this Note and not otherwise defined herein shall have
the meanings assigned in the Credit Agreement.

     This Note is the Construction Loan Note referred to in, evidences the
Construction Loan Advances and the Converted Construction Loan under, and has
been issued by Maker in accordance with the terms of, the Credit Agreement.
Payments on this Note may be evidenced by a grid (if any) attached to this Note
or similar certificates or documents, or by the internal computerized records of
Holder, PROVIDED that any failure of Holder to make any such notation shall not
affect the unconditional obligation of Maker to pay all amounts due hereunder as
and when due. Holder shall be entitled to the benefits of the Credit Agreement
and the other Loan Documents and may enforce the agreements of Maker contained
therein, and Holder may exercise the respective remedies provided for thereby or
otherwise available in respect thereof, all in accordance with the terms
thereof. Holder shall have the right (but not the obligation), in its sole
discretion, to charge any amounts due hereunder not otherwise paid on the due
dates thereof to any account maintained by Maker with Holder.

     All computations of interest with respect to this Note shall be made on the
basis of a 360 day year and the actual number of days elapsed. Unless sooner
accelerated as a result of the occurrence of an Event of Default or as otherwise
provided in the Credit Agreement, principal, accrued and unpaid interest and any
other sums due hereunder shall be due and payable in full, in Dollars and in
immediately available funds on, as applicable: (i) the Construction Loan
Conversion Date if the Constructions Loan Advances are not converted to the
Converted Construction Loan; and (ii) on the Maturity Date of the Converted
Construction Loan if the Construction Loan Advances have been converted to the
Converted Construction Loan.

     Maker has the right under certain circumstances to prepay in whole or in
part the principal of this Note on the terms and conditions specified in the
Credit Agreement.

     Maker agrees that: (i) if any installment of interest, principal or any
other sum due under this Note shall not be paid within ten (10) calendar days
after its due date; or (ii) if any other Event of Default shall occur, then,
upon the happening of any such event, the entire indebtedness with accrued
interest thereon due under this Note shall, automatically or at the option of
Holder, as the case may be as provided in the Credit Agreement, accelerate and
become immediately due and payable without notice. Failure to exercise such
option shall not constitute a waiver of the right to exercise the same in the
event of any subsequent Event of Default. Notwithstanding anything to the
contrary contained herein, upon the occurrence of such an Event of Default or
after maturity or judgment, the interest rate on this Note shall automatically
increase without notice or demand to a per annum rate equal to the Default Rate.

     In the event Maker fails to pay any installment of interest, principal
and/or any other sum due hereunder or under the Credit Agreement for more than
ten (10) days from the date it is due and payable, without in any way affecting
Holder's right to declare an Event of Default to have occurred, a late charge
equal to five (5%) percent of such late payment shall be assessed against Maker
and shall be immediately due and payable without demand or notice of any kind.

<PAGE>

     Maker agrees that no delay or failure on the part of Holder in exercising
any power, privilege, remedy, option or right hereunder shall operate as a
waiver thereof or of any other power, privilege, remedy or right; nor shall any
single or partial exercise of any power, privilege, remedy, option or right
hereunder preclude any other or future exercise thereof or the exercise of any
other power, privilege, remedy, option or right. The rights and remedies
expressed herein and in the Credit Agreement are cumulative, and may be enforced
successively, alternatively, or concurrently and are not exclusive of any rights
or remedies which Holder may or would otherwise have under the provisions of all
applicable laws, and under the provisions of all agreements between Maker and
Holder or between any endorser or guarantor and Holder.

     All agreements between Maker, each Guarantor and Holder are hereby
expressly limited so that in no contingency or event whatsoever, whether by
reason of acceleration of maturity of any of the Obligations or otherwise, shall
the amount paid or agreed to be paid to Holder for the use or the forbearance of
the Obligations exceed the maximum permissible under applicable law. As used
herein, "APPLICABLE LAW" shall mean the law in effect as of the date hereof
provided, however, that in the event there is a change in the law which results
in a higher permissible rate of interest, then this Note, the Credit Agreement
and the other Loan Documents shall be governed by such new law as of its
effective date. In this regard, it is expressly agreed that it is the intent of
Maker and Holder in the execution, delivery and acceptance of the Loan Documents
to contract in strict compliance with the laws of the State of Connecticut from
time to time in effect. If, under or from any circumstances whatsoever,
fulfillment of any provision hereof or of any of the other Loan Documents at the
time of performance of such provision shall be due, shall involve transcending
the limit of such validity prescribed by applicable law, then the obligation to
be fulfilled shall automatically be reduced to the limits of such validity, and
if under for from circumstances whatsoever Holder should ever receive as
interest an amount which would exceed the highest lawful rate, such amount which
would be excessive interest shall be applied to the reduction of the principal
balance of the Loan evidenced by this Note and not to the payment of interest.
This provision shall control every other provision of all agreements between
Maker, each Guarantor and Holder.

     Maker hereby grants Holder a continuing lien, security interest and right
of setoff for all of its Obligations and other liabilities to Holder, whether
now existing or hereafter arising, upon and against all its deposits (general or
special, time or demand, provisional or final), credits, collateral and property
now or hereafter in the possession, custody, safekeeping or control of Holder
or, if Holder is Lender, any entity under common control of FleetBoston
Financial Corporation and its successors and assigns, or in transit to any of
them. Holder may, at any time and from time to time after the occurrence and
during the continuation of an Event of Default, without demand or notice (any
such notice being expressly waived by Maker), apply or set off the same, or any
part thereof, to any Obligation or liability of Maker to Holder, even though
unmatured and regardless of the adequacy of any other collateral securing such
Obligations and liabilities. ANY AND ALL RIGHTS TO REQUIRE HOLDER TO MARSHAL OR
OTHERWISE EXERCISE ITS RIGHTS OR REMEDIES WITH RESPECT TO ANY OTHER COLLATERAL
WHICH SECURES ANY OR ALL OF SUCH OBLIGATIONS

<PAGE>

AND LIABILITIES PRIOR TO EXERCISING ITS RIGHT OF SETOFF WITH RESPECT TO SUCH
DEPOSITS, CREDITS OR OTHER PROPERTY OF MAKER ARE HEREBY KNOWINGLY, VOLUNTARILY
AND IRREVOCABLY WAIVED. The rights of Holder under this paragraph are in
addition to other rights and remedies (including, without limitation, other
rights of setoff) which Holder may have.

     Failure by Holder to insist upon the strict performance by Maker of any
terms and provisions herein shall not be deemed to be a waiver of any terms and
provisions herein, and Holder shall retain the right thereafter to insist upon
strict performance by Maker of any and all terms and provisions of this Note or
any document securing the repayment of this Note.

     MAKER AND HOLDER (BY ACCEPTANCE OF THIS NOTE) MUTUALLY HEREBY KNOWINGLY,
VOLUNTARILY AND INTENTIONALLY WAIVE THE RIGHT TO A TRIAL BY JURY IN RESPECT OF
ANY CLAIM BASED HEREON, ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS NOTE OR
ANY OTHER LOAN DOCUMENTS OR ANY COURSE OF CONDUCT, COURSE OF DEALINGS,
STATEMENTS (WHETHER VERBAL OR WRITTEN) OR ACTIONS OF ANY PARTY, INCLUDING,
WITHOUT LIMITATION, ANY COURSE OF CONDUCT, COURSE OF DEALINGS, STATEMENTS OR
ACTIONS OF THE HOLDER RELATING TO THE ADMINISTRATION OF ANY OF THE LOANS OR
ENFORCEMENT OF THE LOAN DOCUMENTS, AND AGREE THAT NEITHER PARTY WILL SEEK TO
CONSOLIDATE ANY SUCH ACTION WITH ANY OTHER ACTION IN WHICH A JURY TRIAL CANNOT
BE OR HAS NOT BEEN WAIVED. EXCEPT AS PROHIBITED BY LAW, THE MAKER AND THE HOLDER
EACH HEREBY WAIVE ANY RIGHT IT MAY HAVE TO CLAIM OR RECOVER IN ANY LITIGATION
ANY SPECIAL, EXEMPLARY, PUNITIVE OR CONSEQUENTIAL DAMAGES OR ANY DAMAGES OTHER
THAN, OR IN ADDITION TO, ACTUAL DAMAGES. THE MAKER CERTIFIES THAT NO
REPRESENTATIVE, AGENT OR ATTORNEY OF THE LENDER HAS REPRESENTED, EXPRESSLY OR
OTHERWISE, THAT THE LENDER WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO
ENFORCE THE FOREGOING WAIVER. THE MAKER ACKNOWLEDGES AND STIPULATES THAT THE
WAIVERS GRANTED ABOVE ARE MADE KNOWINGLY, VOLUNTARILY AND INTENTIONALLY AND
AFTER FULL CONSULTATION WITH COUNSEL AND CONSTITUTE A MATERIAL INDUCEMENT FOR
THE LENDER TO ACCEPT THIS NOTE AND MAKE THE LOAN EVIDENCED HEREBY.

     MAKER WAIVES DILIGENCE, DEMAND, PRESENTMENT FOR PAYMENT, NOTICE OF
NONPAYMENT, PROTEST AND NOTICE OF PROTEST, AND NOTICE OF ANY RENEWALS OR
EXTENSIONS OF THIS NOTE. MAKER ACKNOWLEDGES THAT IT MAKES THIS WAIVER KNOWINGLY,
VOLUNTARILY, WITHOUT DURESS AND ONLY AFTER CONSIDERATION OF THE RAMIFICATIONS OF
THIS WAIVER WITH ITS ATTORNEYS. MAKER FURTHER ACKNOWLEDGES THAT LENDER HAS NOT
AGREED WITH OR REPRESENTED TO MAKER THAT THE PROVISIONS OF THIS PARAGRAPH WILL
NOT BE FULLY ENFORCED IN ALL INSTANCES.

                                                                   EXHIBIT 10.18

                                      LEASE

                              W I T N E S S E T H:

        Whereas, Tenant is the tenant under a Lease Agreement dated August 30,
1994, as amended (the "Phase I Lease") with respect to certain premises more
particularly described therein located in a building at the northwest corner of
Stelzer Road and Morse Crossing Road, Columbus, Ohio (hereinafter, the "Phase I
Premises");

        Whereas, as of the date hereof, the landlord under the Phase I Lease
("Phase I Landlord") and Landlord will become affiliated as owners and joint
venturers with respect to the Phase I Premises and the premises which are the
subject of this Lease upon completion of the Building to be constructed pursuant
to the terms of this Lease;

        Whereas, Landlord owns a parcel of land adjacent to and located to the
west of the Phase I Premises ("Phase II Land");

        Whereas, Tenant requires expansion space for its business and Landlord
has agreed to construct a building for net lease to Tenant on the Phase II Land
to meet Tenant's expansion needs;

        Whereas, the initial term of the Phase I Lease will expire by its terms
on September 30, 2005 and pursuant to Exhibit G of the Phase I Lease, Tenant has
two 5-year renewal options;

        Whereas, simultaneously with the execution of this Lease, Tenant and

                                       2

        Whereas, Landlord, the Phase I Landlord and Tenant will each secure a
substantial benefit from the execution of this Lease and the amendment of the

amendment of the Phase I Lease to which they are signatory;

        Whereas, Landlord and Tenant are entering into this Lease for the
purpose of setting forth their understanding with respect to the matters set
forth herein.

        NOW, THEREFORE, for good and valuable consideration, the mutual receipt
and legal sufficiency of which are hereby acknowledged, the parties hereto
hereby agree as follows:

                                    ARTICLE 1

             DEMISED PREMISES - TERM - RECIPROCAL EASEMENT AGREEMENT

        Section 1.1 Landlord hereby leases to Tenant the parcel of land
containing approximately 5.352 acres located to the west of the Phase I
Premises, in the City of Columbus, County of Franklin and State of Ohio, as more
particularly described on the Site Plan attached hereto as Exhibit A, together
with the 79,200 square foot building, with a connection to the Phase I Premises,
to be constructed thereon (the "Building") and together with parking at the rate
of 6.5 parking spaces per 1,000 square feet of rentable area (collectively the
"Demised Premises"). This Lease shall be effective, and the parties hereto shall
be bound, as of the date hereof (the "Effective Date"). The term (the "Term") of
this Lease shall commence on the date (the "Commencement Date"), as defined in
Section 6.4 and end on the fifteenth (15th) anniversary of the Rent Commencement
Date (as defined in Section 6.5), or such earlier date as this Lease may
terminate as hereinafter provided (the "Termination Date"). Following the
Commencement Date and the Rent Commencement Date, the parties shall execute a
document in the form of Exhibit G attached hereto setting forth each respective
date, but the failure of either party to execute the document shall not effect
the Commencement Date or the Rent Commencement Date.

        Section 1.2 For purposes of determining the number of rentable square
feet of the Building, Landlord's Architect (as defined in Article 6) will
certify to that measurement upon completion of the Building, which certification
shall be subject to the
<PAGE>   3
                                       3

reasonable approval of or confirmation by Tenant prior to its being finalized.
The parties will execute a document confirming their agreement with Landlord's
Architect, but the failure of either party to do so will not affect the rights
or duties of the parties hereunder.

        Section 1.3 Tenant acknowledges that the Phase II Premises and the Phase
I Premises will be subject to a Reciprocal Easement Agreement ("REA")
substantially in the form attached hereto as Exhibit B. Tenant will cooperate as
reasonably requested by Landlord in executing any documents that may be required
to carry out the requirements of the REA. Tenant further acknowledges that in
connection with the construction of the Phase II Premises, Landlord and
Landlord's agents, representative of public utilities and other persons or
entities may require access to and through the Phase I Premises and Phase I
Landlord and Tenant agree to cooperate as set forth in the REA to enable
Landlord to construct the Phase II Premises, to install and connect utility
lines and communications lines, to build the connection between the Phase I
Premises and Phase II Premises, to provide parking and means of ingress and
egress, and for any other purpose reasonably necessary to carry out the terms of
this Lease provided, however, Landlord agrees that it will take reasonable
precautions in the course of the activities described hereinabove to avoid
interference with the operation of Tenant's business or the use and enjoyment by
Tenant of the Phase I Premises and/or the Phase II Premises but neither Landlord
nor Phase I Landlord shall be liable for any reasonable interruption to Tenant's
business as a result thereof.

        Notwithstanding the foregoing, Landlord will be responsible for any cost
and expense that Tenant may incur as a result of damage to the Phase I Premises
resulting from Landlord's access to the Phase I Premises or otherwise during the
course of construction of the Phase II Premises. Landlord shall prior to the
commencement of any construction provide Tenant with a contemplated schedule of
work with regard thereto and shall provide prior notice to Tenant, which may be
by telephone, of any scheduling changes that may have any effect on the Phase I
Premises.

                                    ARTICLE 2

                          BASIC RENT - ADDITIONAL RENT

        Section 2.1 Commencing on the Rent Commencement Date, and throughout the
Term, Tenant will pay annual basic rent (the "Basic Rent"), in the amounts
determined in accordance with Schedule 1 attached hereto, in equal monthly
installments in advance of the first (1st) day of each month during the Term,
without notice or demand and without any rights of reduction, counterclaim or
offset except as specifically set forth
<PAGE>   4
                                       4

in Articles 12 and 13. If the Rent Commencement Date falls on a day other than
the first day of a calendar month, the first payment which Tenant shall make on
the Rent Commencement Date shall be equal to the proportionate part of the Basic
Rent for the partial month from the Rent Commencement Date to the first day of
the succeeding calendar month. Basic Rent will be paid to Landlord, at the
address of Landlord as above set forth or at such other address as Landlord may
designate in writing from time to time. If the Term terminates on a day other
than the last day of the month, then the installment of Basic Rent for the last
month of the Term will be adjusted accordingly.

        Section 2.2 This Lease shall be deemed to be a "net lease" and Tenant
shall pay to Landlord, absolutely net throughout the Term, without setoff or
offset, the Basic Rent and other charges hereunder, free of any charges,
assessments, impositions or deductions of any kind, except as specifically set
forth herein. Tenant will pay and discharge all costs and expenses incurred in
connection with or arising from the use, occupancy, maintenance, management,
repair and security of the Demised Premises and all other amounts, liabilities,
charges, obligations and other payments which Tenant, under any of the
provisions of this Lease, is now or hereafter obligated to pay or discharge
("Costs"). If Tenant fails to pay all or any part of the Costs when due, then
such payment may be made by Landlord (but Landlord shall not be required to do
so), and Tenant will reimburse Landlord therefor, within twenty (20) days
following notice by Landlord to Tenant, together with interest thereon, at
Fifteen (15%) per cent per annum (the "Default Rate"), from the date of such
notice until reimbursement is made in full. Such reimbursement and interest
shall constitute additional rent hereunder ("Additional Rent") and Landlord
shall have the same rights, and remedies provided for herein or by statute or
otherwise in the case of non-payment of Additional Rent as for non-payment of
Basic Rent.

                                    ARTICLE 3

                        PAYMENT OF TAXES AND ASSESSMENTS

        Section 3.1 Landlord will promptly deliver to Tenant all tax bills
received by Landlord with respect to the Demised Premises and Tenant will pay,
directly to the appropriate governmental authority, before fine, penalty or
interest may be added for nonpayment, all real estate taxes, assessments, water
and sewer rents and other governmental levies and charges (all taxes,
assessments, water and sewer rents and other governmental levies and charges
being hereinafter called "real estate taxes") which are imposed or become a lien
upon the Demised Premises or become payable, during the Term, and will promptly
send Landlord a receipt for such payment or a copy of the tax bill and a copy of
Tenant's cancelled check in payment thereof.

        Section 3.2 In the event any tax bill received by Landlord incorporates
property in addition to the Demised Premises also owned by Landlord then,
notwithstanding the provisions of this Article 3, all taxes respecting the
Demised Premises will be paid by Landlord, and Landlord will thereafter bill
Tenant for Tenant's pro rata share of such tax as reasonably determined by
Landlord and Tenant. Such sum will be treated as Additional Rent hereunder,
which will be due and payable within thirty (30) days following delivery of such
bill to Tenant and otherwise in accordance with the terms of this Lease. In the
event that the real estate taxes are increased as a direct result of a sale or
refinancing of the Demised Premises, the portion of the real estate taxes
attributable to the sale or refinancing shall be the obligation of Landlord and
not Tenant.

        Section 3.3 Tenant shall be responsible for, and shall pay when due, all
installments of owners' association assessments imposed upon the Demised
Premises by the Easton Association, and accruing during the Term. In the event
that Landlord pays any assessments directly to Easton Association with respect
to the Demised Premises, Tenant will reimburse Landlord within twenty (20) days
of request by Landlord. The amount due shall be deemed Additional Rent in
accordance with Section 2.2. Landlord shall, upon request of Tenant, seek
consent of the Easton Association to assign a share of its voting rights in the
Easton Association to Tenant provided that Landlord shall retain rights
appropriate to the owner of the fee interest in the Demised Premises.

will keep the Demised Premises insured for the mutual benefit of Landlord and
Tenant against:

        (1) loss or damage by fire, and such other risks as may be included in
the standard form of extended coverage insurance from time to time available, in
an amount not less than full replacement value, less footings and foundations,
provided that such amount is sufficient to prevent Landlord or Tenant from
becoming a co-insurer within the terms of the applicable policies;

        (2) loss or damage by explosion of high pressure steam boiler, air
conditioning equipment, pressure vessels, motors or similar apparatus, now or
hereafter installed in the Demised Premises, in such limits with respect to any

for the benefit of Landlord and Tenant against claims for bodily injury or
property damage occurring on the Demised Premises, under a policy of general
commercial public liability insurance, bodily injury and death limits of not
less than $5,000,000 for any one occurrence, and $1,000,000 for property damage,
as such amounts may be reasonably increased by Landlord from time to time,
consistent with amounts of insurance carried by prudent landlords of comparable
properties or as reasonably required by any Mortgagee.

        Section 4.3 All required insurance will be effected under policies
issued by insurers reasonably approved by Landlord and licensed to do business
in the State of Ohio. Certificates of such insurance will be delivered by
Landlord to any Mortgagee. At

renewal policy for such insurance or certificate will be delivered to the holder
of the expiring original policy. All such policies will contain agreements by
the insurers that such policies will not be cancelled except upon thirty (30)
days' prior written notice to each named insured and loss payee and will include
effective waivers by the insurer of all rights of subrogation against any named
insured.

        Section 4.4 All required policies of insurance will name Landlord and
Tenant as the insureds as their respective interests may appear and will also
provide for any loss thereunder to be payable to any Mortgagee, pursuant to a
standard mortgagee clause or endorsement or to the party insured thereby.

        Section 4.5 Tenant will reimburse Landlord within twenty (20) days of
request for the premium paid by Landlord, or the amount due shall be deemed
Additional Rent in accordance with Section 2.2.

        Section 4.6 Tenant will carry its own insurance insuring its own
personal property, and its business interest in the Demised Premises, including
business interruption insurance against loss, damage or destruction by fire or

        Section 5.1 Tenant will pay all costs and charges for insurance, heat,
water, gas, electricity, light, telephone, janitorial, repairs, maintenance and
all other expenses related to the Demised Premises in order that Basic Rent
shall be absolutely net to Landlord throughout the Term of this Lease. Tenant
will indemnify Landlord and save it harmless from and against any liabilities
and all costs, expenses, claims or damages incurred as a result of Tenant's
failure to perform its obligations hereunder. Utility service will be directly
metered to the Demised Premises and charged to Tenant.

        Section 5.2 Landlord will enter into a property management contract (the
"Management Contract") with a third party (the "Property Manager"), approved by
Tenant, such approval not to be unreasonably withheld or delayed, pursuant to
which the Property Manager will manage the Demised Premises for the Term and any
Renewal Term. Landlord shall have the right to assign the Management Contract in
the event of the sale of the Demised Premises; provided, however, that
throughout the term, the
<PAGE>   8
                                       8

Property Manager shall be subject to Tenant's reasonable approval. All
Management Contracts shall contain a thirty (30) day right to terminate with or
without cause. Upon request of Tenant, Landlord shall terminate the Management
Contract. Upon such termination, Landlord shall enter into a new Management
Contract which shall again be subject to Tenant's reasonable approval as set
forth above. If Tenant shall at any time occupy the entire Phase I Premises and
Phase II Premises, Tenant may, at its option, take over the management of the
Demised Premises, with a Property Manager selected by Tenant, who shall be
subject to Landlord's approval, such approval not to be unreasonably withheld or
delayed.

        Section 5.3 At any time that Tenant fails to make any of the payments
required by this Article 5 when due, then such payment may be made by Landlord,
and Tenant will reimburse Landlord as provided in Section 2.2.

     LANDLORD AND TENANT IMPROVEMENTS; CHANGES AND ALTERATIONS; SURRENDER OF
                                DEMISED PREMISES

        Section 6.1 (1) Landlord shall proceed to cause the Landlord
Improvements (as hereinafter defined) to be developed and constructed in a good
and workmanlike manner, in compliance with all applicable laws, ordinances,
rules and regulations and in accordance with the Schematic Design, the Design
Documents and the Construction Documents (collectively, the "Plans" and together
with the Specifications to be prepared by Landlord and approved by Tenant, all
as more particularly described in Exhibit C and in this Article, the "Plans and
Specifications."). "Landlord Improvements" shall mean the Building and
connecting structure, the parking area and the site improvements which Landlord
will construct in a manner that is consistent with the standards for Class A
office buildings in the Easton community of suburban Columbus, Ohio (the "Easton
Standards").

        (2) Landlord shall cause the firm of Acock Associates (which firm has
been approved by Tenant), ("Landlord's Architect") to prepare the Plans and
Specifications. Landlord shall deliver to Tenant, for and subject to its
approval, in accordance with the time frames (the "Time Frames") set forth in
Exhibit B, (i) the Schematic Design; (ii) the Design Documents, and (iii) the
Construction Documents. Tenant shall deliver written response to Landlord within
twenty (20) days of receipt of each of the Schematic Design, the Design
Documents and the Construction Documents. Tenant's failure to respond within
twenty (20) days to each of Landlord's requests shall be deemed approval.
Landlord agrees to incorporate Tenant's comments into the documents to which
they
<PAGE>   9
                                       9

relate; provided, however, that Landlord shall not be required to incorporate
such comments of Tenant to the extent such comments would, in Landlord's
reasonable judgment, require the Landlord Improvements to deviate in any
material way from the Easton Standards, or, subject to the next sentence,
increase Landlord's Costs (as defined in Schedule 1) above those set forth in
the preliminary budget prepared by Landlord and approved by Tenant (the
"Preliminary Budget") attached hereto as Exhibit D. With respect to changes
requested by Tenant that would increase Landlord's Costs, Landlord shall
incorporate those changes provided that the requested change is consistent with
the Easton Standards and will not increase the Basic Rent for the First Rental
Period to an aggregate amount that is in excess of $17.50 per rentable square
foot (the "Cap"). As set forth in Exhibit D, Landlord's Costs shall include a
payment equivalent to 5% of the total cost of construction, not including any
Land acquisition, interest or financing costs. To the extent that Tenant's
comments (i) cause a delay in Landlord's ability to adhere to the time periods
in Exhibit C, or (ii) increase Landlord's Costs above the Cap, Landlord will
give Tenant an opportunity to withdraw such comments. In the event that Tenant
does not withdraw the comment, Landlord shall incorporate the comment into the
documents to which they relate but any resulting delay in the time periods in
Exhibit C shall be deemed a Tenant Delay (as defined in Section 6.4(c) and any
additional costs above the Cap shall be deemed Additional Rent and shall be
reimbursed to Landlord after the completion of the work to which the same is
applicable in accordance with Section 2.2.

        (3) Tenant's approval rights shall include (i) the final design of the
Building, including, without limitation, the massing and spatial character of
the exterior, lobby and other common areas, all pursuant to architectural review
committee approval of the Easton Association (including the typical office
floorplate, the placement of features thereon, core location and layout, support
spaces for building core and column bay dimension); (ii) the final design of the
internal improvements, including, without limitation, bathrooms, mechanical
systems and life safety systems; and (iii) all exterior improvements.

        Section 6.2 (1) Landlord Improvements shall be developed on an
"open-book" basis, with Landlord bidding out all trades on a competitive basis.
All consultants engaged by Landlord shall be subject to Tenant's reasonable
approval, not to be unreasonably withheld or delayed, after review by Tenant of
the proposals submitted by each such consultant. Landlord shall prepare and
furnish to Tenant (i) bid packages which Landlord has prepared including
specifications, instructions to bidders, and AIA form Contractor's Qualification
Statement and (ii) a list of all proposed bidders, all subject to Tenant's
approval before bid packages are distributed. Tenant shall either deliver
written approval to Landlord within twenty (20) days of receipt of the materials
described in (i) and (ii) above or shall be deemed to have approved if no
response is
<PAGE>   10
                                       10

received by Landlord within twenty (20) days. If Tenant shall not approve the
bid packages, the list of prospective bidders, or the consultants, Tenant shall
explain the reasons therefor to Landlord and Landlord shall continue to make
reasonable efforts to respond to Tenant's objection until rectified to Tenant's
reasonable satisfaction. Tenant shall also have approval rights in the same
manner as described above, within twenty (20) days of request, 1) if the
construction is bid to multiple prime contractors, of each prime contractor and
the scope of the portion of Landlord's Improvements to be included in each prime
contract, and 2) of all subcontracts in excess of $100,000. Any reasonable
suggestions made by Tenant within twenty (20) days of Landlord's request with
respect to the bidding process shall be incorporated by Landlord and if Landlord
rejects Tenant's proposed suggestion, Landlord will respond to Tenant explaining
the reasons therefor. Tenant and its representatives shall have the right to be
present at and participate in the negotiation of all bids received with respect
to the bid packages prepared by Landlord for amounts in excess of $100,000.
Tenant approves Bovis Lend Lease, Inc. or another construction manager
satisfactory to both parties as Landlord's construction manager at a fee of 2.5%
or at a fee to be agreed to by the parties.

        (2) Tenant and Tenant's representative shall have the right at all times
during the business hours of Landlord or Landlord's general contractor, prime
contractors, construction manager or consultants, as the case may be, and at
such others times as Tenant may reasonably request, to audit, inspect and review
the Plans and Specifications or the other documents referred to in this Article
so long as such review does not unreasonably delay the Landlord Improvements.

        Section 6.3 In coordination with Landlord's schedule for the preparation
of the Plans and Specifications, Tenant, at Tenant's sole cost and expense,
shall secure the preparation of all necessary plans and specifications ("Tenant
Plans") for the design and construction of the interior improvements which are
necessary or desirable to prepare the Building for Tenant's initial occupancy
(the "Tenant Improvements"). The Tenant Plans shall be subject to Landlord's
review and approval which shall not be unreasonably delayed or withheld and
shall be deemed approved if Landlord does not respond within twenty days. Any
changes by Tenant to the Tenant Plans, once approved by Landlord, shall again be
subject to Landlord's review and approval which shall not be unreasonably
delayed or withheld and shall be deemed approved if Landlord does not respond
within twenty (20) days. Tenant shall cause the construction and installation of
the Tenant Improvements to be in compliance with the approved Tenant Plans.
Tenant shall, in connection with the construction and installation of the Tenant
Improvements, comply with all applicable laws, ordinances, rules and regulations
and shall obtain all permits and approvals required or necessary thereunder in
order for Tenant to perform the Tenant
<PAGE>   11
                                       11

Improvements. The contractor selected by Tenant to perform the Tenant
Improvements shall be subject to Landlord's reasonable approval.

        Section 6.4 (1) Landlord shall notify Tenant not less than forty-five
(45) days prior to the date when the Landlord Improvements shall be
Substantially Completed (As defined below; such date shall hereinafter be the
"Commencement Date", corresponding to Item Numbered 13 on Exhibit C.). Upon such
notice, Landlord shall permit Tenant reasonable access to the Building for the
construction and installation of the Tenant Improvements. Such access shall be
at Tenant's own risk, shall not unreasonably interfere with or delay completion
of the Landlord Improvements by Landlord, and shall be only after Tenant has
obtained the insurance required under this Lease. Landlord and Tenant agree to
cooperate during the construction of the Landlord Improvements and the Tenant
Improvements, to coordinate the scheduling of such work and to keep each other
informed as to their respective progress.

        (2) (i) In the event that the Commencement Date does not occur by the
date eighteen (18) months after the date hereof, as such date may be extended by
Unavoidable Delays and Tenant Delays (as such terms are defined below) (the
"Target Date"), then Tenant may either remain in the premises then being
occupied by Tenant (provided that Landlord's obligation to reimburse Tenant for
its direct out-of-pocket expenses or Tenant's right to deduct such sum from
payment of Basic Rent (as described below) shall not exceed market rent and
shall not include any penalty that Tenant may incur as a result of becoming a
"holdover tenant") or Tenant may lease temporary premises of comparable size to
the Phase II Building in the Columbus area by notice to Landlord given within
thirty (30) days after the Target Date. If Tenant remains in the premises then
being occupied by Tenant, which premises have fewer square feet than the Demised
Premises, Tenant may lease additional space so that the temporary space,
including Tenant's existing premises are substantially equivalent in size to the
Demised Premises. Landlord shall have the right to approve the terms of the
leasing of the temporary premises, such approval not to be unreasonably delayed
or withheld and, provided that the terms of the temporary leasing shall be at
the then market rent on the then market terms for similar properties in the
location of the temporary premises, Landlord shall be deemed to have approved.
Provided Landlord has approved or is deemed to have approved the terms of the
leasing, Landlord shall reimburse Tenant for its direct out-of-pocket expenses
incurred in connection with leasing the temporary premises and/or remaining in
Tenant's existing premises as described above, Tenant may, at Tenant's option,
deduct the sum from payments of Basic Rent due hereunder.

        (ii) In the event that the Commencement Date does not occur by the date
thirty-six (36) months after the date hereof ("Outside Date"), as such date may
be extended by
<PAGE>   12
                                       12

Tenant Delays, either party shall have the right to terminate this Lease by
notice to Landlord given within ten (20) days after the Outside Date, whereupon
Landlord shall reimburse Tenant for its direct out-of-pocket expenses incurred
in connection with this transaction, and neither party shall have any further
rights or responsibilities hereunder, except those specifically stated to
survive a termination hereof. Notwithstanding the foregoing, in the event that
Landlord shall exercise its right to terminate in accordance with the previous
sentence, and at any time within 24 months thereafter Landlord shall desire to
enter into another lease for the Demised Premises, Landlord shall not enter into
such lease until it has given Tenant not less than 30 days notice of the
contemplated transaction and if Tenant shall notify Landlord within 10 days
after receipt of Landlord's notice that it wishes to reinstate this Lease on all
of its terms, Landlord and Tenant shall enter into an agreement whereby this
Lease shall be reinstated. Other than as specifically set forth in this Section,
Landlord shall have no liability and Tenant shall have no rights, including
without limitation, any right to terminate this Lease, as a result of the delay
in Landlord's completion of the Landlord Improvements.

        (3) As used herein, "Substantially Completed" means that Landlord has so
completed the Landlord Improvements that Tenant is permitted to enter the
Demised Premises to commence construction of the Tenant Improvements, with
appropriate means of ingress and egress and access to the Building systems, in a
manner that shall not materially adversely affect Tenant's ability to diligently
construct the Tenant Improvements, and without undue delays or interference with
Tenant's ability to complete the Tenant Improvements, and including, without
limitation, the completion of the following items in any portion of the Demised
Premises made available to Tenant for construction of the Tenant Improvements:
freight elevators, fire stairs, and the electrical, mechanical and life safety
systems (each to the extent necessary for Tenant to expeditiously commence and
complete the Tenant Improvements). As used herein, "Unavoidable Delays" means
one day for each day that the Commencement Date is delayed by strikes, labor
troubles, abnormal or unusual weather conditions, accidents, conditions of
supply and demand, or any other cause whatsoever beyond Landlord's control,
including but not limited to, laws, governmental preemption, any order,
requirement, rule or regulation of any governmental, quasi-governmental,
judicial or military authority, national emergency, war, unrest or other
emergency. "Tenant Delays"" means one day for each day that the Commencement
Date is delayed by (i) any request by Tenant that Landlord delay in proceeding
with any segment or part of the Landlord Improvements, (ii) any changes or
requests for changes by Tenant to the Landlord Improvements which at the time of
such change or request Tenant approves in writing as a Tenant Delay (and if
Tenant fails to do so, Landlord shall not make such change), (iii) any acts or
omissions of Tenant or its agents, employees or contractors, (iv) any delay
<PAGE>   13
                                       13

by Tenant in delivery of its approvals or submissions after the date that
Tenant's response was required to be given as set forth in this Article (except
in cases where automatic approval shall apply in which event no Tenant Delay
shall occur) and (v) any displacement of any portion of the Landlord
Improvements from its place in Landlord's construction schedule resulting from
any of the causes for delay referred to in clauses (i) through (iv).

        (4) Not less than seven (7) business days prior to the substantial
completion date (as defined in the AIA Contract Documents), and when the Demised
Premises are in condition described in subsection (e) below, Landlord shall
furnish Tenant with a detailed list of punch list items which, in Landlord's
reasonable judgment, will not be completed by the substantial completion date
(as described in the AIA Contract Documents). During such seven (7) business day
period, Landlord and Tenant shall conduct a formal "walk through" of the Demised
Premises in order to develop a final list of punch list items. Following such
substantial completion date, Landlord shall use all reasonable efforts to
complete the final list of punch list items and, to the extent said items are
not completed within thirty (30) days thereafter, Landlord shall furnish Tenant
with an explanation as to the reasons therefor and an estimated final completion
date for said items and thereafter continue to use reasonable efforts to
complete said items as soon as practicable.

        (5) On the substantial completion date (as defined in the AIA Contract
Documents), all of the Building's sanitary, heating, air conditioning,
mechanical and other systems shall have been completed and shall be in good
operating condition, except for minor adjustments which may be required, the
lobby areas of the Building shall have been substantially completed, and all
construction debris shall have been removed therefrom, and functional elevator
service shall be provided; Landlord and Tenant shall have obtained a temporary
or permanent certificate of occupancy for the Building and for any other portion
of the Demised Premises for which the municipality typically issues a
certificate of occupancy; in addition, the parking area and access to and from
the adjacent public roadways shall be available.

        Section 6.5 The Rent Commencement Date shall be the earlier of (a) the
ninety-first day after Tenant occupies the Demised Premises for the conduct of
its business, or (b) the first day following the tenth (10th) month anniversary
of the Commencement Date. In the event that the Commencement Date is delayed as
a result of a Tenant Delays, the Rent Commencement Date shall occur on the date
that the Rent Commencement Date would have occurred but for the number of days
of Tenant Delays.

                                       14

        Section 6.6 Landlord will contribute to Tenant a sum equal to Fifteen
($15.00) Dollars per rentable square foot of the Building (which amount Landlord
agrees to increase, subject to the Cap, to a maximum of Thirty-Five ($35.00)
Dollars per rentable square foot of the Building at the request of Tenant (the
"Allowance") toward the costs of Tenant Improvements (the "Work Costs"). The
total amount of the Allowance will be included in Landlord's Cost for the
calculation of Basic Rent as described on Schedule 1. Any Work Costs in excess
of the Allowance shall be paid by Tenant. Tenant may use the Allowance for any
cost and/or expense related to the Tenant Improvements, including but not
limited to all direct and/or indirect costs all of which shall be included in
the Work Costs, whether applied to the Tenant Improvements or to any Allowance
during a Renewal Term. In the event the total cost of the Tenant Improvements
shall be less than the Allowance Tenant may apply the difference towards the
payment of Rent hereunder.

        Section 6.7 The Allowance shall be paid by Landlord toward the invoices
received for the construction of the Tenant Improvements, and shall be paid in
accordance with the following procedures:

        (1) Tenant shall provide Landlord, not more often than once per calendar
month, with an invoice prepared and certified by a Vice President or other
comparable officer of Tenant, setting forth the Work Costs payable since the
last such invoice, together with such other documents as Landlord shall
reasonably require evidencing the work performed or materials utilized for which
payment is being requested and certifying that all disbursements previously made
by Landlord under this Section have been applied toward payment of the Work
Costs covered by and described in the previous invoices.

        (2) Landlord shall pay to Tenant, within thirty (30) days of receipt of
the documentation described above, the Work Costs set forth on the invoice. Upon
exhaustion of the Allowance, it shall become Tenant's responsibility to pay the
Work Costs, and Tenant shall provide Landlord with reasonable evidence of such
payment.

        (3) All items of Tenant Improvements, excluding trade fixtures, shall
become the property of Landlord upon expiration or earlier termination of this
Lease, and shall remain on the Demised Premises.

        Section 6.8 In addition to the other provisions set forth in this
Article 6, Landlord and Tenant agree that:

        (1) Each shall require all contractors retained by it to take any and
all safety measures reasonably required to protect Landlord and Tenant and their
respective agents,
<PAGE>   15
                                       15

contractors and employees from injury or damage caused by or resulting from the
performance of the construction of the Landlord Improvements and the Tenant
Improvements.

        (2) All construction contracts in connection with the Landlord
Improvements and the Tenant Improvements shall contain provisions that obligate
the contractors to (i) carry public liability and property damage insurance,
with the limitations as would be typically carried by other contractors working
on similar construction projects in the Columbus area, naming Landlord and
Tenant as additional insureds; (ii) indemnify, defend and hold harmless Landlord
and Tenant from and against any claims, costs, losses, expenses (including
attorneys' fees and disbursements), liabilities and damages any of them may
suffer on account of the negligence of the contractor; and (iii) carry workmen's
compensation insurance.

        (3) All warranties contained in the construction contracts entered into
by Landlord in connection with the Landlord Improvements or by Tenant in
connection with the Tenant Improvements shall be assignable to the extent
obtainable in such contracts.

        (4) The contractors engaged by Landlord for performance of Landlord
Improvements and by Tenant for performance of Tenant Improvements shall be
bonded in such amounts and by such companies as shall be reasonable for
contractors performing similar work in the vicinity of suburban Columbus.

        (5) The review and approval by Tenant of the Plans and Specifications is
solely for the benefit of Tenant, and, in reviewing and approving the same,
Tenant assumes no liability for the design of the Landlord Improvements or the
adequacy thereof, nor shall such review or approval by Tenant release Landlord
from any obligation or liability in respect thereof.

        (6) The review and approval by Landlord of the Tenant Plans is solely
for the benefit of Landlord, and, in reviewing and approving the same, Landlord
assumes no liability for the design of the Tenant Improvements or the adequacy
thereof, nor shall such review or approval by Landlord release Tenant from any
obligation or liability in respect thereof.

        Section 6.9 Tenant, at Tenant's election, may install an identifying
sign on the Demised Premises, the design and location of which shall be subject
to the review and approval of Landlord, which approval will not be unreasonably
withheld, and the approval of the Easton Architectural Review Committee. Any
sign will comply with
<PAGE>   16
                                       16

applicable Requirements (hereinafter defined), shall be maintained by and at the
expense of Tenant, and may be removed by Tenant at the end of the Term. Tenant
will repair any damage caused by the removal.

        Section 6.10 At any time after completion of the Improvements, Tenant
may make changes, additions and alterations to the Demised Premises as Tenant
shall deem necessary or desirable ("Alterations"), provided that Tenant shall
first obtain Landlord's consent, only with respect to structural Alterations,
which will not be unreasonably withheld or delayed. All Alterations, other than
Tenant's trade fixtures, will become a part of the Demised Premises. Tenant will
have no obligation to restore the Demised Premises at the end of the Term unless
requested to do so by Landlord at the time of making any Alteration.

        Section 6.11 In the event that, in connection with the exercise of a
Renewal Option as described below in Article 18, Tenant shall perform its own
Alterations toward which Landlord has contributed an Allowance, the Allowance
shall be paid by Landlord in accordance with the following procedures:

        (1) Tenant shall provide Landlord, not more often than once per calendar
month, with an invoice prepared and certified by an officer of Tenant, setting
forth the Work Costs payable since the last such invoice together with such
other documents as Landlord shall reasonably require evidencing the work
performed or materials utilized for which payment is being requested, and
certifying that all disbursements previously made under this Section 6.11 have
been applied toward payment of the Work Costs covered by and described in the
previous invoices.

        (2) Landlord shall pay to Tenant, within thirty (30) days of receipt of
the documentation described above, the Work Costs set forth on the invoice.
Following final disbursement of the Allowance, Tenant shall be responsible to
pay the Work Costs, and Tenant shall provide Landlord with reasonable evidence
of such payment.

        Section 6.12 On the last day of the Term, as extended by any Renewal
Term (as hereinafter defined) Tenant will deliver the Demised Premises to
Landlord, broom clean, in good order, condition and repair, ordinary wear and
tear excepted. Tenant shall remove its furniture, furnishings and portable
equipment and trade fixtures.

        Section 6.13 Tenant will not hold over its occupancy after the
expiration of the Term, including any Renewal Terms. It Tenant holds over,
Tenant will pay one and one-half the Basic Rent then in effect for each month
during the period of hold over. In
<PAGE>   17
                                       17

addition, if the Demised Premises are not surrendered upon the expiration of the
Term, including any Renewal Term, Tenant hereby indemnifies Landlord against
liability resulting from any delay by Tenant in so surrendering the Demised
Premises, including, without limitation, any claims made by any succeeding
tenant or prospective tenant founded upon such delay. Landlord will use good
faith efforts to avoid incurring damages in connection with any subsequent
leasing but Landlord shall be permitted to act in a commercially reasonable
manner. In the event that Landlord shall enter into a new lease for the Demised
Premises, or any part thereof, Landlord shall provide Tenant with written notice
of the Commencement Date of such new lease not less than thirty (30) days prior
thereto and within ten business days of execution thereof.

the Building's systems and adjacent parking areas, subject to reasonable wear
and tear. Tenant, at Tenant's expense, will make all repairs as set forth above
when required to keep the Demised Premises in good order and condition. Landlord
will make structural repairs to the Building, including the roof and shall
maintain the roof to be free of leaks, as and when needed to keep the structure
and roof in good order and condition; provided, however, that Tenant shall be
responsible for the costs of structural repairs and roof repairs, if and to the
extent that the need for such repairs arises out of the performance of Tenant
Improvements, any negligence of Tenant or its agents or employees or any failure
by Tenant to comply with the terms of this Lease. Landlord shall be responsible
for any repair costs to the Demised Premises resulting from the negligence of
Landlord or its agents or its employees in the course of performing Landlord's
repair obligations hereunder, or in connection with the exercise by Landlord of
any of Landlord's rights of entry to the Demised Premises. Landlord will assign
to Tenant all warranties received by Landlord in connection with construction of

                      RIGHT TO PERFORM COVENANTS OF TENANT

        Section 11.1 If Tenant fails to make any payment or perform any other
act on its part to be made or performed under this Lease, Landlord, after not
less than twenty (20) days' notice to Tenant (except in case of an emergency,

employ counsel as reasonably required. Landlord may not pay any Basic Rent or
Additional Rent owed by Tenant hereunder. All reasonable sums paid by Landlord
and all reasonable expenses in connection therewith shall be deemed Additional
Rent hereunder and shall be payable to Landlord as provided in Section 2.2.

                                   ARTICLE 12

                              DAMAGE OR DESTRUCTION

        Section 12.1 In case of damage to or destruction of the Leased Premises,
this Lease shall, except as provided below, remain in full force and effect.
Landlord shall repair and restore the Landlord Improvements and Tenant
Improvements (but not any of Tenant's furnishings, equipment or trade fixtures,
for which Tenant shall be responsible). Landlord shall reasonably and in good
faith allocate the insurance proceeds between the reconstruction costs of the
Landlord Improvements and Tenant Improvements. Tenant shall pay to Landlord, as
Additional Rent, the amount of any deductible, and the amount of any shortfall
in insurance proceeds. Notwithstanding any such damage or destruction, Tenant
shall remain liable for the payment of all Basic Rent and Additional Rent
payable pursuant to the terms of this Lease; to the extent of rent insurance,
and Basic Rent shall otherwise be abated in proportion to the amount of space in
the Demised Premises that is damaged until repairs are completed.

        Section 12.2 If (a) either (i) more than fifty percent (50%) of the
Building is destroyed by fire or other casualty, or (ii) an area of the Building
which is critical to Tenant's operation, and used for a specialized purpose, but
does not consist of general office space, conference rooms, cafeteria,
bathrooms, corridors, secretarial stations or other non-critical areas, is
destroyed by fire or other casualty, causing a cessation of Tenant's business,
and cannot be rebuilt within two hundred seventy (270) days, (b) at the time of
the fire or other casualty, there are less than three (3) years remaining in the
Term, as extended by any Renewal Terms for which Tenant has already exercised a
Renewal Option, and (c) Tenant does not, within forty-five (45) days after such
fire or other casualty exercise its next Renewal Option, then either Tenant or
Landlord may, at such
<PAGE>   20
                                       20

party's option, terminate this Lease by notice to the other within forty-five
(45) days after such fire or other casualty. Upon such termination, the Basic
Rent and Additional Rent shall be apportioned as of the date of such damage or
destruction, Tenant shall vacate and surrender possession of the Demised
Premises, and neither party shall have any further rights or obligations
hereunder except those which are specifically stated to survive a termination
hereof.

                                   ARTICLE 13

                                  CONDEMNATION

        Section 13.1 If all or any substantial portion of the Demised Premises,
the Building, the parking area and/or access to and from public roadways is
taken by or under threat of condemnation so as to render the Demised Premises
wholly untenantable, then this Lease will automatically terminate as of the date
of the vesting of title to such property in the condemning authority. If such
taking does not render the Demised Premises wholly untenantable, then this Lease
will not terminate but subject to Landlord immediately repairing any damages
caused by the said taking at Landlord's sole cost and expense, will continue in
full force and effect in accordance with its terms, except that the Base Rent
will be adjusted to fairly reflect the portion of the Demised Premises, the
Building or the Land which was so taken. Landlord will not be liable to Tenant
for any inconvenience or interruption to Tenant's business occasioned by any
such taking. Subject to the following sentence, Landlord will be entitled to
receive the entire award made by the condemning authority for any such taking.
The Tenant shall have the right to make a claim against the condemning authority
for such claims which it may have and as may be allowed by law, for costs
directly incurred by the Tenant and resulting from such condemnation and for
severance damages. Landlord will promptly notify Tenant of the institution of
any condemnation proceeding affecting the Leased Premises.

                                   ARTICLE 14

                              DEFAULTS AND REMEDIES

        Section 14.1 The occurrence of anyone or more of the following shall
constitute an "Event of Default" under this Lease by Tenant:

        (1) If Tenant fails to make any payment of Basic Rent, Additional Rent
or any other payment required to be made by Tenant under this Lease within ten
(10) days of the date when due, except that on any single initial occasion in
any calendar year during the
<PAGE>   21
                                       21

Term hereof, Landlord shall provide Tenant with a notice in the event that any
payment is not received when due and Tenant shall not be in default provided
that the payment to which the notice refers is made within five (5) days of
Landlord's notice; or

        (2) If a Default (as defined in the Phase I Lease) by Tenant shall occur
under the Phase I Lease, or in the event that Tenant shall enter into the Phase
III Lease or the Phase IV Lease, any Event of Default under the Phase III Lease
or the Phase IV Lease shall be an Event of Default under this Lease provided
that the Landlord hereunder shall be the same Landlord as under the Phase III
Lease or the Phase IV Lease at the time that such Default or Event of Default
shall occur; or

        (c) If Tenant fails to observe or perform any other covenant, condition
or provision of this Lease to be observed or performed by Tenant, and such
failure shall continue for a period of thirty (30) days after notice thereof by
Landlord; provided, however, that if the nature of Tenant's default is such that
more than thirty (30) days are reasonably required for its cure, then Tenant
shall not be deemed to be in default hereunder if Tenant commences such cure
within said thirty (30) day period and thereafter diligently prosecutes such
cure to completion.

        Section 14.2 In the event of any Event of Default, Landlord may, at
Landlord's option, exercise any one or more of the rights and remedies available
to a landlord in the State of Ohio to redress such default, consecutively or
concurrently, including, without limitation, the rights and remedies described
in this Section.

        (1) Landlord may elect to terminate Tenant's right to possession of the
Demised Premises upon thirty (30) days' written notice to Tenant. Following such
a termination, Landlord may re-enter, take possession of the Demised Premises
and remove any persons or property by legal action.

        (2) Following re-entry by Landlord, Landlord may relet the Demised
Premises for a term longer or shorter than the Term and upon any reasonable
terms, including the granting of rent concessions to the new tenant. Landlord
may alter, refurbish or otherwise change the character or use of the Demised
Premises in connection with such reletting. Landlord shall not be required to
relet for any use or purpose which Landlord may reasonably consider injurious to
its property or to any tenant which Landlord may reasonably consider
objectionable. No such reletting by Landlord following a default by Tenant shall
be construed as an acceptance of the surrender of the Demised Premises. If rent
received upon such reletting exceeds the rent received under this Lease, Tenant
shall have no claim to the excess.
<PAGE>   22
                                       22

        (3) Following the termination of the Lease, Landlord shall have the
right to recover from Tenant the following damages:

        (1) All unpaid Basic Rent, Additional Rent and other charges for
    the period prior to re-entry.

        (2) An amount equal to the Basic Rent and Additional Rent lost during
    any period during which the Demised Premises are not relet, plus Landlord's
    reasonable expenses incurred in connection with the termination of this
    Lease, Landlord's re-entry upon the Demised Premises, and with such
    reletting.

        (3) The difference between the Basic Rent reserved under this Lease and
    the amount actually received by Landlord after such reletting, as such
    amounts accrue.

        (4) Landlord may elect, at any time, in lieu of any further deficiency
    pursuant to Paragraphs (ii) and (iii) above, as and for liquidated and
    agreed final damages, a sum equal to the difference between (x) the amount
    of Basic Rent and Additional Rent for the period which otherwise would have
    constituted the unexpired portion of the Term, less (y) the then fair and
    reasonable rental value of the Demised Premises, for the same period, as
    determined by a court of competent jurisdiction, both discounted to present
    value, less (z) the aggregate amount of deficiencies theretofore collected
    by Landlord pursuant to Paragraphs (ii) and (iii) above for the same period.

        (4) In the event that Tenant remains in possession following termination
and Landlord does not elect to re-enter, Landlord may recover all back rent or
other charges, and shall have the right to cure any nonmonetary default and
recover the cost of such cure from Tenant.

        (5) The foregoing remedies shall not be exclusive, but shall be in
addition to all other remedies and rights provided under applicable law, and no
election to pursue one remedy shall preclude resort to another consistent
remedy.

        (6) No action of Landlord, other than express written notice of
termination pursuant to the provisions of this Lease, shall terminate this
Lease.

        Section 14.3 The parties hereto waive trial by jury in any action,
proceeding or counterclaim brought by either of the parties against the other
(except for personal injury or property damage) on any matters whatsoever
arising out of or in any way connected
<PAGE>   23
                                       23

with this Lease, the relationship of Landlord and Tenant, Tenant's use or
occupancy of the Demised Premises, or for the enforcement of any remedy under
any statute, emergency or otherwise. If Landlord commences any proceeding
against Tenant for the payment of Basic Rent or Additional Rent, Tenant will not
interpose any counterclaim of whatever nature or description in any such
proceeding (unless failure to impose such counterclaim would preclude Tenant
from asserting in a separate action the claim which is the subject of such
counterclaim), and will not seek to consolidate such proceeding with any other
action which may have been or will be brought in any other court by Tenant.

        Section 14.4 Landlord shall be in default if it fails to perform any
term, condition, covenant or obligation required under its lease for a period of
thirty (30) days after written notice thereof from Tenant to Landlord; provided,
however, that if the term, condition, covenant or obligation to be performed by
Landlord is such that it cannot reasonably be performed within thirty (30) days,
such default shall be deemed to have been cured if Landlord commences such
performance within said thirty (30) day period and thereafter diligently
undertakes to complete the same. Following a default by Landlord as described in
this Section, Tenant shall have the right to perform the obligation of Landlord
and Landlord shall be liable to Tenant for any costs incurred by Tenant in the
performance thereof and any actual damages sustained by Tenant as a result
thereof.

                                   ARTICLE 15

                         CUMULATIVE REMEDIES - NO WAIVER

        Section 15.1 The specific remedies to which Landlord or Tenant may
resort under the terms of this Lease are cumulative and are not intended to be
exclusive of any other remedies or means of redress to which they may be
lawfully entitled in case of any breach or threatened breach by either of them
of any provision of this Lease. The failure of Landlord to insist in any one or
more cases upon the strict performance of any of the covenants of this Lease, or
to exercise any option herein contained, shall not be construed as a waiver or
relinquishment for the future of such covenant or option. No waiver, change,
modification or discharge by either party hereto of any provision in this Lease
shall be deemed to have been made or shall be effective unless expressed in
writing and signed by the party to be charged. In addition to the other remedies
in this Lease, Landlord and Tenant shall be entitled to the restraint by
injunction of the violation, or attempted or threatened violation, of any of the
covenants, conditions or provisions of this
<PAGE>   24
                                       24

Lease or to a decree compelling performance of any of such covenants, conditions
or provisions.

                                  SUBORDINATION

        Section 16.1 This Lease and all rights of Tenant hereunder shall be
subject and subordinate at all times to any Mortgage or Mortgages and any
renewals or replacements thereof, which now are or hereafter become liens on the
Demised Premises, provided the holder of any Mortgage (a "Mortgagee") shall
deliver to Tenant an agreement reasonably satisfactory to Tenant and in
recordable form stating that in the event of default under such Mortgage, the
tenancy herein created shall not be disturbed, provided no Event of Default have
occurred and be continuing hereunder. Tenant shall join in such agreement,
confirming a covenant by Tenant to attorn to such Mortgagee, as Tenant's
landlord hereunder. Any such agreement shall provide that neither Mortgagee, nor
anyone claiming by, through or under the Mortgagee, including a purchaser at a
foreclosure sale, shall be (a) liable for any act or omission of any prior
landlord, except with respect to the continuing failure of the successor
landlord to perform such prior landlord's obligations, (b) subject to any
defense or offset which Tenant may have against any prior landlord, (c) bound by
any payment of Basic Rent, or other money payable by Tenant to Landlord
hereunder, including as Additional Rent, which Tenant may have made to any prior
landlord more than thirty (30) days in advance of the date upon which such
payment was due, (d) bound by any obligation to make any payment to or on behalf
of Tenant, or (e) bound by any amendment or modification of this Lease made
without its consent after the date of the Mortgage provided Tenant has received
notice of the Mortgage.

                                   ARTICLE 17

                                EXPANSION OPTIONS

        Section 17.1 This Lease shall be separate and distinct from the Phase I
Lease, and no act or omission of a party to one shall have any effect on the
rights and obligations of the parties to the other, except as specifically set
forth herein.

        Section 17.2 Tenant (but only the Tenant named in this Lease, and
provided that Tenant is still in occupancy of two-thirds of the Demised
Premises) shall have the option (the "Phase III Option") to lease from Landlord,
an additional building, to be constructed by Landlord on vacant land located due
west of the Demised Premises which will contain
<PAGE>   25
                                       25

approximately 70,000 square feet, parking at the rate of 6.5 parking spaces per
1,000 square feet of rentable area and a connection from the Phase III Premises
to the Demised Premises (the "Phase III Premises."). A site plan of the proposed
Phase III Premises is attached hereto as Exhibit E. The Phase III Option may be
exercised by Tenant at any time not later than sixteen (16) months from the
Effective Date (as defined in Article 1), by notice to Landlord, provided that
on the date on which Tenant sends such notice and on the date of the execution
and delivery by Tenant of the Phase III Lease, no monetary or other material
Event of Default has occurred under this Lease or the Phase I Lease and is then
continuing beyond any applicable notice and grace periods. If Tenant shall fail
to timely exercise the Phase III Option, then Tenant's rights to lease Phase III
Premises shall terminate.

        Section 17.3 (a) If Tenant exercises the Phase III Option, Landlord and
Tenant shall execute and deliver a lease of Phase III Premises (the "Phase III
Lease") for a fifteen (15) year term, together with an amendment to this Lease
and the Phase I Lease providing that (i) the term of the Phase I Lease and this
Lease will be coterminous with the term of the Phase III Lease and (ii) for an
equivalent number of renewal options and for the equivalent number of renewal
terms in the Phase I Lease and this Lease as in the Phase III Lease. In the
event that Tenant shall exercise its Renewal Option as described in Article 18
or if this Lease is otherwise extended to accommodate this Section 17.3, the
Renewal Rent and or extension rent shall be calculated in the same manner as in
Section 18.3 below. The Phase III Lease shall be upon and subject to all of the
terms and conditions contained in this Lease, and identical in form to, and
completed to the same extent as, this Lease, except (a) the demised premises
shall be as described on the site plan attached hereto as Exhibit F, (b) the
term of the Phase III Lease shall commence on the Commencement Date (as
determined in accordance with the same procedure as in Article 6 hereof), and
end on the date immediately preceding the fifteenth (15th) anniversary of the
term commencement date provided for therein, (c) the basic rent in the Phase III
Lease shall be calculated using the same formula but with the then current
amounts for Landlord's Cost and Pay Rate, (d) the Phase III Option shall not be
included, (e) the premises demised thereunder shall be developed in accordance
with Exhibit E and (f) the amount of the Allowance shall be fifteen Dollars
($15.00) per rentable square foot of the building, subject to C.P.I. increase
from the date hereof to the date of the Phase III Lease. If Landlord or Tenant
fails to execute and deliver the Phase III Lease and the amendments to the Phase
I Lease and to this Lease described above within thirty (30) days after the
tender thereof by Landlord to Tenant, provided such lease and the amendments
comply with this Section or Tenant approves any changes made thereto, the
responding party may at any time between the end of such thirty (30) day period
and the execution and delivery of the Phase III Lease and the amendments notify
the non-
<PAGE>   26
                                       26

responding party that the Phase III Option is void, and thereupon the Phase III
Option shall be of no further force or effect. The Phase III Lease shall be
separate and distinct from this Lease and the Phase I Lease, and no act or
omission of a party to one shall have any effect on the rights and obligations
of the parties to the other, except as specifically set forth herein.

        (b) Tenant acknowledges that Landlord does not currently own the
property on which the Phase III Premises would be developed, but that Landlord
has an option to purchase such land. In the event that Landlord has not
previously delivered a copy of the option to Tenant, which Landlord shall
endeavor to do, then a copy of the option is being delivered by Landlord to
Tenant simultaneously upon execution of this Lease. If Tenant exercises the
Phase III Option, Landlord shall use commercially reasonable efforts to acquire
the property by exercising the option in order to develop the Phase III
Premises. Tenant waives any right, under statute or otherwise, to rescind the
Phase I Lease or the Phase II Lease or to offset against Tenant's obligations
under the Phase I Lease or the Phase II Lease any damages which may result from
Landlord's failure for any reason to deliver possession of the Phase III
Premises or otherwise to perform its obligations hereunder, provided, however,
that in the event that Landlord shall be unable to or shall elect not to acquire
the Phase III Premises, Landlord will assign all of its rights to acquire the
Phase III Premises to Tenant.

        Section 17.4 Tenant (but only the Tenant named in this Lease, and
provided that Tenant is still in occupancy of two-thirds the entire Demised
Premises) shall have the option (the "Phase IV Option") to lease from Landlord,
an additional building, to be constructed by Landlord on vacant land located
north of the Phase III Premises which will contain parking at the rate of 6.5
parking spaces per 1,000 square feet of rentable area and a connection between
the Phase III Premises and the Phase IV Premises (the "Phase IV Premises."). A
site plan of the proposed Phase IV Premises is attached hereto as Exhibit F. The
Phase IV Option may be exercised by Tenant at any time not later than One
Hundred and fifty (150) days following the acquisition by Landlord of the Phase
III Premises by notice to Landlord, provided that on the date on which Tenant
sends such notice and on the date of the execution and delivery by Tenant of the
Phase IV Lease, no monetary or other material Event of Default has occurred
under the Phase I Lease, the Phase II Lease or the Phase III Lease and is then
continuing beyond any applicable notice and grace periods. If Tenant shall fail
to timely exercise the Phase IV Option, then Tenant's rights to lease Phase IV
Premises shall terminate.

        Section 17.5 (a) If Tenant exercises the Phase IV Option, Landlord and
Tenant shall execute and deliver a lease of Phase IV Premises (the "Phase IV
Lease") for a fifteen
<PAGE>   27
                                       27

(15) year term, together with an amendment to the Phase I Lease, the Phase II
Lease and the Phase III Lease providing that (i) the term of the Phase I Lease,
the Phase II Lease and the Phase III Lease will be coterminous with the term of
the Phase IV Lease and (ii) for an equivalent number of renewal options and for
the equivalent number of renewal terms in the Phase I Lease, the Phase II Lease
and the Phase III Lease as in the Phase IV Lease. In the event that Tenant shall
exercise its Renewal Option as described in Article 18 or if this Lease is
otherwise extended to accommodate this Section 17.5, the Renewal Rent and or
extension rent shall be calculated in the same manner as in Section 18.3 below.
The Phase IV Lease shall be upon and subject to all of the terms and conditions
contained in this Lease, and identical in form to, and completed to the same
extent as, this Lease, except (a) the demised premises shall be as described on
Exhibit F, (b) the term of the Phase IV Lease shall commence on the Commencement
Date (as determined in accordance with the same procedures as in Article 6
hereof), and end on the date immediately preceding the fifteenth (15th)
anniversary of the term commencement date provided for therein, (c) the basic
rent in the Phase IV Lease shall be calculated using the same formula but with
the then current amounts for Landlord's Cost and Pay Rate. (d) the Phase IV
Option shall not be included, (e) the premises demised thereunder shall be
developed in accordance with Exhibit F and (f) the amount of the Allowance shall
be the amount of the Allowance for the Phase III Premises, subject to C.P.I.
increase from the date of the Phase III Lease to the date of the Phase IV Lease.
If Landlord or Tenant fails to execute and deliver the Phase IV Lease and the
amendments to the Phase I Lease, the Phase II Lease and the Phase III Lease,
described above, within thirty (30) days after the tender thereof by Landlord to
Tenant, provided such lease and the amendments comply with this Section or
Tenant approves any changes made thereto, the responding party may at any time
between the end of such thirty (30) day period and the execution and delivery of
the Phase IV Lease and the amendments notify the non-responding party that the
Phase IV Option is void, and thereupon the Phase IV Option shall be of no
further force or effect. The Phase IV Lease shall be separate and distinct from
each of the Phase I Lease, the Phase II Lease and the Phase III Lease and no act
or omission of a party to one shall have any effect on the rights and
obligations of the parties to the other, except as specifically set forth
herein.

        (b) Tenant acknowledges that Landlord does not currently own the
property on which the Phase IV Premises would be developed but that Landlord has
an option to purchase such land. In the event that Landlord has not previously
delivered a copy of the option to Tenant, which Landlord shall endeavor to do,
then a copy of the option is being delivered by Landlord to Tenant
simultaneously upon execution of this Lease. If Tenant exercises the Phase IV
Option, Landlord shall use commercially reasonable efforts to acquire the
property by exercising the option in order to develop the Phase IV Premises.
<PAGE>   28
                                       28

Tenant waives any right, under statute or otherwise, to rescind the Phase I
Lease, the Phase II Lease or the Phase IV Lease or to offset against Tenant's
obligations under the Phase I Lease, the Phase II or the Phase III Lease any
damages which may result from Landlord's failure for any reason to deliver
possession of the Phase IV Premises or otherwise to perform its obligations
hereunder, provided, however, that in the event that Landlord shall be unable to
or shall elect not to acquire the Phase IV Premises, Landlord will assign all of
its rights to acquire the Phase IV Premises to Tenant.

                                     RENEWAL

        Section 18.1 Tenant (but only the Tenant named in this Lease and
provided that Tenant is still in occupancy of two-thirds of Demised Premises)
shall have the option (the "Renewal Option") to extend the term of this Lease
for three (3) additional periods of five (5) years each (each a "Renewal Term").
The first Renewal Term (the "First Renewal Term") shall commence on the date
immediately succeeding the Termination Date and shall end on the fifth (5th)
anniversary of the Termination Date. The second Renewal Term (the "Second
Renewal Term") shall commence on the date immediately succeeding the fifth (5th)
anniversary of the Termination Date and shall end on the tenth (10th)
anniversary of the Termination Date. The third Renewal Term (the "Third Renewal
Term") shall commence on the date immediately succeeding the tenth (10th )
anniversary of the Termination Date and shall end on the fifteenth (15th)
anniversary of the Termination Date.

        Section 18.2 Each Renewal Option shall be exercisable by Tenant
delivering to Landlord notice of Tenant's exercise thereof (a "Renewal Notice"),
at least 12 months prior to the first day of the Renewal Term in question. Time
is of the essence with respect to the giving of the Renewal Notice. Upon the
giving of a Renewal Notice with respect to this Lease, Tenant shall be deemed to
have simultaneously exercised its renewal option under the Phase I Lease. The
exercise of a Renewal Option under the Phase I Lease (incorporated therein by
amendment simultaneously with the execution of this Lease) shall be deemed to be
exercise of a Renewal Option under this Lease. Upon the giving of the Renewal
Notice with respect to the Third Renewal Term, Tenant shall have no further
right or option to extend or renew the term of this Lease or any Renewal Term,
except as may otherwise be provided in Article 17 in connection with an
Expansion Option.

        Notwithstanding the foregoing, Tenant may only exercise a Renewal
Option, and an exercise thereof shall only be effective, if at the time of
Tenant's exercise of such
<PAGE>   29
                                       29

Renewal Option and on the day preceding the commencement of the Renewal Term in
question, the following conditions are satisfied, (i) this Lease is in full
force and effect and (ii) no monetary or material non-monetary default on the
part of Tenant is continuing beyond any applicable notice or cure period then
exists under this Lease.

        Section 18.3 If Tenant exercises a Renewal Option, the Renewal Term
shall be upon the same terms, covenants and conditions as those contained in
this Lease, except that basic rent during each Renewal Term ("Renewal Basic
Rent") shall be equal to (a) ninety-five (95%) percent of the "fair market
rental" rate for offices and uses ancillary thereto in Class A buildings of
comparable size, quality and location, and payable by tenants of comparable size
and credit in suburban Columbus, Ohio, for a comparable triple net lease, upon
the same terms and conditions as set forth herein and with respect to the Third
Renewal Term only, Tenant shall have no further right to renew this Lease; or
(b) such other amount as is otherwise acceptable to both parties; provided,
however, that the Renewal Basic Rent for the First Renewal Term shall not be
less than the Basic Rent in effect for the last year of the Term, and the
Renewal Basic Rent for each succeeding Renewal Term shall not be less than the
Renewal Basic Rent in effect for the last year of the preceding Renewal Term. In
the absence of any agreement between the parties on the amount of the Renewal
Basic Rent, the Renewal Basic Rent shall be determined as provided below.

        Section 18.4 Tenant may not exercise a Renewal Option unless Tenant has
exercised all prior Renewal Options. Upon its exercise of the third (3rd)
Renewal Option, Tenant shall have no further right or option to renew this
Lease.

        Section 18.5 For purposes of determining the Renewal Basic Rent, the
following procedure shall apply:

           (1) Landlord and Tenant shall, at the location in the City of
Columbus specified by Landlord (by notice to Tenant given at least thirty (30)
days prior to the date set forth therein) at the time and on a business day not
earlier than nine (9) months prior to the first day of the Renewal Term in
question and not later than six (6) months prior to the first day of the Renewal
Term in question, exchange their respective written initial determinations of
the Renewal Term Basic Rent stated as a dollar amount per square foot of
rentable area of the Demised Premises. (Landlord's initial determination of the
Renewal Term Basic Rent is referred to as "Landlord's Initial Determination" and
Tenant's determination is referred to as "Tenant's Initial Determination").
<PAGE>   30
                                       30

            (2) If the parties shall have exchanged determinations in accordance
with the foregoing, they shall attempt to agree upon the Renewal Term Basic
Rent. If, within ten (10) days after the date of such exchange, they have not so
agreed they shall attempt to agree upon an independent real estate appraiser to
act hereunder. If, within twenty (20) days after the date of such exchange, they
have not so agreed upon such an independent real estate appraiser, such
independent real estate appraiser shall be appointed by the American Arbitration
Association. The independent real estate appraiser so agreed upon by the parties
or so appointed is herein called the "Renewal Term Appraiser". The fee of the
Renewal Term Appraiser and of the American Arbitration Association shall be
borne equally by Landlord and Tenant. Each party shall pay its own counsel fees
and expenses, if any, in connection with any determination under this Article.

            (3) The Renewal Term Appraiser, by notice to the parties, shall
establish a date, time and location in the City of Columbus, no earlier than 10
days after the date of such notice, at which either party may, if it elects,
deliver to the Renewal Term Appraiser a revised written determination of the
Renewal Term Basic Rent ; provided, however, that (a) Landlord's revised
determination of the Renewal Term Basic Rent shall be no higher than Landlord's
Initial Determination thereof and no lower than 95% of Landlord's Initial
Determination thereof, and (b) Tenant's revised determination of the Renewal
Term Basic Rent shall no lower than Tenant's Initial Determination thereof and
no higher than 105% of Tenant's Initial Determination thereof.

            (4) If both parties elect to deliver revised determination, they
shall do so simultaneously. The Renewal Term Appraiser shall furnish each party
with a copy of any revised determination delivered by the other. As used herein
the term "Landlord's Final Determination" shall mean (i) if Landlord shall have
delivered a revised determination in accordance with this Section, such revised
determination, or (ii) otherwise, Landlord's Initial Determination. As used
herein the term "Tenant's Final Determination" shall mean (i) if Tenant shall
have delivered a revised determination in accordance with this Section, such
revised determination, or (ii) otherwise, Tenant's Initial Determination.

            (5) The Renewal Term Appraiser shall conduct such hearings and
investigations as he or she may deem appropriate and shall, within thirty (30)
days of the date of his or her designation, choose either Landlord's Final
Determination of the Renewal Term Fair Market Rent or Tenant's Final
Determination of the Renewal Term Fair Market Rent, and the choice by the
Appraiser shall be conclusive and binding upon Landlord and Tenant.

            (6) The Renewal Term Appraiser appointed pursuant to this Article
shall be an independent real estate appraiser with at least ten (10) years'
experience in valuation of properties that are similar in character to the
Building, and a member of the Appraisal Institute (or its successor). The
Renewal Term Appraiser shall not have the power to add to, modify or change any
of the provisions of this Lease.

            (7) It is expressly understood that any determination of the Renewal
Term Basic Rent pursuant to this Article shall be based on the criteria stated
in this Article.

            Section 18.6 After a determination has been made of the Renewal Term
Basic Rent for any Renewal Term, the parties shall execute and deliver to each
other an instrument setting forth the Renewal Term Basic Rent, as determined
pursuant to this Article and, if applicable, provided however, that failure of
either party to execute a written supplement shall not affect the rights and
duties of the parties hereunder.

            Section 18.7 If the final determination of the Renewal Term Basic
Rent with respect to any Renewal Term shall not be made on or before the first
day of such Renewal Term, then pending such final determination (and subject to
retroactive adjustment as provided below), payments of Basic Rent shall be made
based upon the rent for the last month of the prior term. If the Renewal Term
Appraiser chooses Tenant's Determination of the Renewal Term Basic Rent (or if
the Renewal Term Basic Rent as finally determined is otherwise different from
Landlord's Determination thereof), Tenant shall be entitled to a credit against
the Basic Rent equal to the amount of Tenant's overpayment of Basic Rent.

            Section 18.8 In the event that Tenant advises Landlord
simultaneously with the exercise of a Renewal Option that it wishes to perform
Alterations at the commencement of or during any Renewal Term, and requests an
additional Allowance from Landlord for that purpose, Landlord will provide the
additional Allowance, in the amount requested by Tenant, up to $5.00 per
rentable square foot, amortized over the remaining Term of the Lease, as
renewed, with an interest factor equal to the 5-year Treasury Rate plus 300
basis points and the Renewal Term Basic Rent will be increased accordingly.

            This indemnification and the obligations of Tenant hereunder shall
survive the termination of this Lease and continue in full force and effect so
long as any matters shall exist against which Tenant has agreed to indemnify
Landlord pursuant to the terms hereof, and shall not be affected by the
happening from time to time of any event, including, but not limited to, any
failure, omission, delay or lack of action on the part of Landlord to enforce,

available to Tenant the "Phase I" Environmental Report that Landlord has
obtained with respect to the Phase II Land and that Landlord has not made any
representation or warranty as to any Hazardous Substance. The provisions of this
Section shall not be deemed to limit the right of Tenant to name Landlord as a
party defendant in any action brought by any third party, including any
governmental or administrative entity, for damages which such third party
alleges have been caused by environmental conditions affecting or related to the
Demised Premises which existed prior to the Commencement Date, and Landlord
shall indemnify and hold Tenant harmless from and against any liabilities,
losses and costs, including Tenant's reasonable counsel fees and any required
remediation which Tenant may incur by reason of any such third party claim.

                                  MISCELLANEOUS

            Section 29.1 Upon any sale of the Demised Premises by Landlord, the
grantee shall assume in writing the obligations of Landlord hereunder. Provided
that such assumption agreement is obtained, the obligations of Landlord under
this Lease shall not
<PAGE>   39
                                       39

be binding upon Landlord named herein after the sale, conveyance, assignment or
transfer by such Landlord (or upon any subsequent landlord after the sale,
conveyance, assignment or transfer by such subsequent landlord) of its interest
in the Building or the Demised Premises, as the case may be, and in the event of
any such sale, conveyance, assignment or transfer, Landlord shall be and hereby
is entirely freed and relieved of all covenants and obligations of Landlord
hereunder. The partners, shareholders, directors, officers, members and
principals, direct and indirect, of Landlord and/or Tenant (collectively, the
"Parties") shall not be liable for the performance of Landlord's obligations
under this Lease. Tenant shall look solely to Landlord to enforce Landlord's
and/or Tenant's obligations hereunder and shall not seek any damages against any
of the Parties. The liability of Landlord for Landlord's obligations under this
Lease shall be limited to Landlord's interest in the Demised Premises and Tenant
shall not look to any other property or assets of Landlord or the property or
assets of any of the Parties in seeking either to enforce Landlord's obligations
under this Lease or to satisfy a judgment for Landlord's failure to perform such
obligations.

            Section 29.2 As used herein, the term "Affiliate" shall mean, with
respect to Tenant, an entity which controls, is controlled by or is under common
control with Tenant, any entity to which all or substantially all of the stock
or assets of Tenant are transferred, or any entity into or with which Tenant
shall be merged, and, with respect to Landlord, an entity under the control,
directly or indirectly, of The Georgetown Company.

            Landlord hereby waives any statutory or common law lien or right of
distraint against any and all of Tenant's inventory, equipment trade fixtures
personality, accounts receivable and proceeds thereof.

            Section 29.3 This Lease may be executed in separate counterparts
which shall together constitute one document.

                                SECURITY DEPOSIT

            Section 30.1 Within 30 days of the execution of this Lease, Tenant
shall delivery to Landlord a standby, unconditional, irrevocable letter of
credit in the amount of $693,000 naming Landlord as beneficiary, issued or
confirmed by The Bank of New York permitting partial draws thereon, and
otherwise in form reasonably acceptable to Landlord as a security deposit under
this Lease.. Tenant shall from time to time cause its letter of credit to be
renewed (either automatically under the terms thereof or by
<PAGE>   40
                                       40

amendment thereto or by replacement thereof) in the amounts described below no
later than 30 days prior to any expiration date thereof so that its letter of
credit remains in effect for 30 days after the scheduled expiration of the Term;
if Tenant fails timely to renew its letter of credit (or if such letter of
credit renews automatically under its terms, and such automatic renewal is
terminated by the issuer of such letter of credit), then Landlord shall have the
right to draw thereon, and retain the amounts so drawn as a security deposit
until such time as Landlord receives a replacement letter of credit satisfying
the requirements of this article 30. Upon the occurrence of an Event of Default,
Landlord may draw upon the letter of credit (but only to the extent required to
cure the Event of Default) and apply the proceeds thereof to perform any of
Tenant's unperformed obligations under this Lease. Tenant hereby irrevocably
appoints Landlord its true and lawful attorney-in-fact , such power of attorney
being coupled with an interest, with full power of substitution, to do any one
of more of the following in its sole discretion upon the occurrence of an Event
of Default under this Lease: (1) demand, collect, receive, sue for, compound and
give acquittance for any and all amounts which may be or become due or payable
with respect to the letter of credit and all funds evidenced thereby, (2)
execute any and all withdrawal receipts or other orders for the payment of money
drawn from the letter of credit, (3) file any claim or institute any proceeding
with respect to the letter of credit, and (4) take any other action which
Landlord may deem necessary or appropriate to protect and preserve the right,
title and interest of Landlord under this Lease. Provided no Event of Default
has occurred hereunder, Tenant may reduce the amount of the letter of credit by
20-% of the original amount on each anniversary of the date of this Lease except
that the letter of credit shall not fall below $115,000 during the term hereof.

            Notwithstanding the foregoing, if, during the Term, Tenant is
granted an investment grade rating (which, for purposes hereof, shall mean a
rating of BB or better) by Moody's Investors Service, Inc. or Standard & Poor's
Ratings Services, a division of McGraw Hill, Inc., Landlord, upon written
request from Tenant and provided no Event of Default shall then exist, shall
return to Tenant any letter of credit held by Landlord pursuant to this Article
and no letter of credit or other security deposit shall thereafter be required
from Tenant pursuant to this Lease.
