6.       Appendix C OPTIONS of the Lease and Paragraph 9 OPTION TO RENEW of the
         First Amendment is amended effective September 1, 2000 by deleting the
         existing language for Option to Extend, Option to Expand, Right of
         First Refusal, and Basement Vault and Anteroom in its entirety and
         replacing with the following OPTION TO RENEW:

                  Provided Tenant is not in default on the date notice is given
                  and at expiration of the term, Tenant shall have the right to
                  extend the term for three (3) five-year renewal options for
                  the Premises at a rate which shall be mutually determined by
                  Landlord and Tenant as follows: If Tenant desires to exercise
                  its Option to Renew, it shall notify Landlord no later than
                  twelve (12) months prior to the expiration of the then current
                  Term. Within one (1) month after such notification, Landlord
                  shall notify Tenant of its determination of the current rate,
                  which will include the Base Rent. If Tenant agrees with such
                  determination, it shall so notify Landlord. If Tenant does not
                  agree, then during the thirty (30) day period following
                  Landlord's notice to Tenant of the rate, Landlord and Tenant
                  shall negotiate to determine a mutually acceptable rate. If
                  such parties are unable to reach agreement as to such rate
                  within said thirty (30) day period, this renewal option will
                  be of no force or effect and the Lease will

                  terminate. If the parties do reach agreement as to such rate
                  within said period, then the Term shall be extended for the
                  appropriate period, upon the same terms and conditions set
                  forth in the Lease, except that the Base Rent shall be as
                  mutually determined and except that there shall be no Tenant
                  Improvement Allowance (unless such items are agreed to by
                  Landlord and Tenant).

7.       RELOCATION OPTION FOR ANNEX PREMISES. Landlord shall have the right to
         substitute for the Annex Premises other premises (herein referred to as
         the "new premises") at the Property provided: (i) the new premises
         shall be contiguous to the Tower Premises, (ii) Landlord shall give
         Tenant at least thirty (30) days' written notice before making such
         substitution, and the parties shall execute an amendment to the Lease
         confirming the substitution within thirty (30) days after either party
         shall request the same: and (iii) if Tenant is already occupying the
         Annex Premises, then upon completion of the Relocation (as hereinafter
         defined), Landlord shall pay the direct, out-of-pocket, reasonable
         expenses of Tenant in moving from the Annex Premises to the new
         premises and improving the new premises so that they are substantially
         similar to the Annex Premises, and, (b) such move shall be made during
         evenings, weekends, or otherwise so as to incur the least inconvenience
         to Tenant. As used herein, "Relocation" means that Tenant has vacated
         the Annex Premises and has taken possession of the new premises. In the
         event Tenant refuses to effectuate the Relocation in accordance with
         this Paragraph 7, then, in that event, in addition to other remedies
         available to Landlord in law or equity or under the terms of this
         Lease, Landlord shall have the right to cancel and terminate this Lease
         effective thirty (30) days after the date of the original notification
         by Landlord. Upon Relocation, the term "Annex Premises" as used in this
         Lease, shall mean the new premises. The parties, within thirty (30)
         days after the Relocation, shall execute an amendment of this Lease
         confirming the substitution and any other changes to the terms of this
         Lease occasioned by this Paragraph 7.

8.       Exhibit A of the Lease and Paragraph 17 of the First Amendment is
         amended by adding the floor plan for the Second Floor Annex Premises.

9.       Exhibit B of the Lease and referenced meeting notes from the original
         construction and Paragraph 19 of the First Amendment are amended
         effective September 1, 2000 by deleting the existing language in its
         entirety and replacing with the following Work Letter:

                  WORK LETTER.

                  A.       Initial Plan. Tenant will perform certain leasehold
         improvement work in the Annex Premises in substantial accordance with
         the plans to be prepared by Infrastructure, Inc. (collectively "Initial
         Plan"), a copy of which shall be attached as Schedule 1. Such work, as
         shown in the Initial Plan and as more fully detailed in the Working
         Drawings (as defined and described in Paragraph B



<PAGE>   6

The Bank of Nashville
Second Amendment to Lease
Page 6 of 11


         below), shall be hereinafter referred to as the "Work". All plans,
         drawings, specifications and other details describing the Work which
         have been or are hereafter furnished by or on behalf of Tenant shall be
         subject to Landlord's approval, which Landlord agrees shall not be
         unreasonably withheld, delayed or conditioned. Landlord shall not be
         deemed to have acted unreasonably if it withholds its approval of any
         plans, specifications, drawings, or other details or of any Additional
         Work (as defined in Paragraph E below) because, in Landlord's
         reasonable opinion, the Work, as described in any such item, or the
         Additional Work, as the case may be: (a) is likely to adversely affect
         the Building systems, the structure of the Building or the safety of
         the Building and/or its occupants; (b) might impair Landlord's ability
         to furnish services to Tenant or other tenants in the building; (c)
         would increase the cost of operating the building; (d) would violate
         any governmental laws, rules or ordinances (or interpretations
         thereof); (e) contains or uses hazardous or toxic materials or
         substances; (f) would adversely affect the appearance of the building;
         (g) might adversely affect another tenant's premises; (h) is prohibited
         by any ground lease affecting the Building or any mortgage, trust deed
         or other instrument encumbering the Building; or (i) is likely to be
         substantially delayed because of unavailability of shortage of labor or
         materials necessary to perform such work or the difficulties or unusual
         nature of such work. The foregoing reasons, however, shall not be the
         only reasons for which Landlord may withhold its approval, whether or
         not such other reasons are similar or dissimilar to the foregoing.
         Neither the approval by Landlord of the Work or the Initial Plan or any
         other plans, drawings, specifications or other items associated with
         the Work nor Landlord's monitoring of the Work shall constitute any
         warranty by Landlord to Tenant of the adequacy of the design for
         Tenant's intended use of the Premises.

                  B.       Working Drawings; performance of the Work.

                           (1) If not included as part of the Initial Plan
                  attached hereto, Tenant shall prepare or cause to be prepared
                  final working drawings and specifications for the Work (the
                  "Working Drawings") based on and consistent with the Initial
                  Plan and the other plans, drawings, specifications, finish
                  details and other information furnished by Tenant to Landlord
                  and approved by Landlord pursuant to Paragraph A above. The
                  Working Drawings shall incorporate final mechanical,
                  electrical and plumbing plans, and shall include a final
                  telephone layout and special electrical connections, if any.
                  So long as the Working Drawings are consistent with the
                  Initial Plan, Landlord shall approve the Working Drawings
                  within five (5) days after receipt of same from Tenant by
                  initialing and returning to Tenant each sheet of the Working
                  Drawings or by executing Landlord's approval form then in use,
                  whichever method of approval Landlord may designate.

                           (2) The parties acknowledge that Landlord is not an
                  architect or engineer, and that the Work will be designed and
                  performed by independent



<PAGE>   7

                  architects, engineers and contractors, selected by Tenant,
                  subject to Landlord's prior written approval. Accordingly,
                  Landlord shall have no liability to Tenant under the Lease for
                  any errors or omissions in the Initial Plan and the Working
                  Drawings and for any defects in the Work. In the event of such
                  errors, omissions, or defects, Landlord shall cooperate in any
                  action Tenant desires to bring any architects, engineers or
                  contractors.

                           (3) Upon Landlord's approval, Tenant shall promptly
                  commence with the construction of the Work and thereafter
                  diligently prosecute the same to completion. All Work shall be
                  in full compliance with the Americans with Disabilities Act
                  and with any and all applicable local building codes and
                  regulations. Except as may be otherwise provided in the
                  Initial Plan or Working Drawings, the Work will be performed
                  using materials, quantities and procedures which are then
                  generally in use by Landlord as building standards, or better.

                           (4) Notwithstanding any other provision of this Work
                  Letter, Landlord and Tenant agree as follows:

                               (a) Tenant's contractors must perform in
                           such a manner as to not cause or permit to be caused

                           rule or regulation of the Lease or this Work Letter
                           by Tenant.

                               (b) Tenant and Tenant's contractors shall
                           maintain at all times during the construction for the
                           Work and for the benefit of Landlord, its officers
                           and employees, such insurance as Landlord may
                           reasonably require, including, without limitation,
                           such hazard, builder's risk, worker's compensation
                           and other similar insurance as is required under the
                           laws of the State of Tennessee or any political
                           subdivision thereof.

                                (c) Tenant shall deliver or cause to be
                           delivered to Landlord prior to the commencement of
                           construction of any of the Work, (i) certificates of
                           such insurance as is required hereunder and such
                           certificates shall name Landlord as an additional
                           insured and contain provisions that the policies
                           shall not be cancelled without thirty (30) days prior
                           written notice to Landlord: (ii) evidence that any
                           and all governmental permits and licenses required
                           for the construction of the Work have been duly
                           secured and remain in full force and effect; and
                           (iii) such other similar assurances which Landlord
                           may reasonably require from time to time.

                                (d) To the extent that Tenant pays directly,
                           or causes to be paid, any contractors, supplier or
                           materialmen, Landlord may from time to time require
                           from evidence of payment to all such parties during

                           completion, Tenant shall deliver to Landlord a waiver
                           of or release of liens signed by all contractors,
                           suppliers, or materialmen.

                           (5) During the construction period, Landlord shall
                  have the right, but not the obligation to inspect the
                  Premises, and all improvements made to the Premises comprising
                  the Work to reasonably determine whether the Work is
                  satisfactory. If any Work does not comply with the Working
                  Drawings, Landlord shall, within twenty-four (24) hours of
                  Landlord's inspection, notify Tenant in writing of such
                  noncompliance, including the specifics thereof, whereupon
                  Landlord may require non-complying portions of the Work to be
                  removed and reconstructed to so comply. No such inspection by
                  Landlord, or failure to inspect by Landlord, shall make
                  Landlord liable in any manner to Tenant under the Lease for
                  any defects, errors or omissions in connection with the Work
                  or any errors or omissions in the Initial Plan or Working
                  Drawings.

                  C.       Landlord's Contribution. "Cost of the Work" means all
         costs and expenses of the Work, including, without limitation, (i) the
         cost of the Initial Plan and Working Drawings, (ii) the cost of all
         labor (including overtime) and materials constituting the Work, (iii)
         general conditions (including rubbish removal, hoisting permits,
         temporary facilities, safety and protection, cleaning, tools,
         blueprints and reproduction, telephone, temporary power, filed
         supervision and the like); (iv) the cost of premiums for worker's
         compensation, public liability, casualty and other insurance charged by
         contractors; (v) contractors' charges for overhead and fees; and (vi)
         architectural and engineering fees.

                           (1) Provided that Tenant has satisfied the
                  requirements set forth above and below and is not in default
                  under the Lease or the Workletter, Landlord shall make a
                  contribution, on the terms hereinafter set forth, equal to One
                  Hundred Twenty-nine Thousand Eight Hundred Forty and 60/100
                  Dollars ($129,840.60) (based upon $11.65 per square foot of
                  rentable area of the Annex Premises (the "Landlord's
                  Contribution")) toward the Cost of the Work under the
                  Workletter. Subject to the limitations hereinafter set forth,
                  Landlord's contribution shall also be applied towards Tenant's
                  cost for architectural design and mechanical drawings.
                  Landlord shall not be liable for more than the Landlord's
                  Contribution. Any amount of the tenant allowance not utilized
                  by the Tenant in the improvement of the Annex Premises shall
                  be applied to base rent.

                           (2) Landlord shall make periodic progress payments
                  (usually monthly) of the Landlord's Contribution toward the
                  Cost of the Work as work progresses under the Workletter,
                  within thirty (30) days after presentation by Tenant to
                  Landlord of invoices for the Cost of the Work and

                  duly executed waivers of liens from all contractors,
                  subcontractors and materialmen furnishing labor, equipment or
                  materials for the performance of the Work.

                           (3) After payment of any amounts toward the Cost of
                  the Work under the Workletter, Landlord may pay the Landlord's
                  Contribution to Tenant, or Landlord may, in its discretion,
                  make or cause to be made (through the construction escrow or
                  otherwise) payment directly to Tenant's contractors or vendors
                  or jointly with Tenant, in progress payments as described
                  above. Landlord may use the Landlord's Contribution to
                  reimburse or pay itself amounts owed by Tenant pursuant to the
                  provisions of the Workletter.

                           (4) Notwithstanding any other provision of this
                  Lease, the payment of the Landlord's Contribution shall be
                  subject to Landlord's right to set-off.

                  the Lease. This Work Letter sets forth the entire agreement of
                  Tenant and Landlord regarding the Work.

                           (2) If final working drawings and specifications are
                  included as part of the Initial Plan attached hereto, then
                  whenever the term "Working Drawings" is used in this Agreement
                  such term shall be deemed to refer to the Initial Plan and all
                  supplemental plans and specifications approved by Landlord.

                           (3) If the Initial Plan or Working Drawings for the
                  Work require the construction and installation of more fire
                  hose cabinets, telephone closets, or electrical closets than
                  the number regularly provided Landlord in the core of the
                  Building, then Tenant will pay to Landlord all costs and
                  expenses incurred by Landlord for the construction and
                  installation of such additional fire hose cabinets, telephone

                  for and property acquired by Landlord pursuant to the Lease
                  and this Work Letter. Nothing in the Lease or this Work Letter
                  shall be construed as agreement by Landlord to pass any
                  investment tax credits through to Tenant.

                           (5) Time is of the essence of this Work Letter.

                           (6) Tenant's failure to pay when due any amounts owed
                  by Tenant under this Work Letter, or Tenant's failure to
                  perform any other obligation of Tenant under this Work Letter,
                  will constitute a default by Tenant under the Lease, and
                  Landlord will have all the rights and remedies granted to
                  Landlord under the Lease for failure by Tenant to perform its
                  obligations under the Lease. Landlord's failure to pay when
                  due any amounts owed by Landlord under this Work Letter, or
                  Landlord's failure to perform any other obligation of Landlord
                  under this Work Letter, will constitute a default by Landlord
                  under the Lease, and Tenant will have all the rights and
                  remedies granted to Tenant under the Lease for failure by
                  Landlord to perform its obligations under the Lease.

                           (7) All words and phrases in this Work Letter have
                  the same meanings given to them in the Lease, unless otherwise
                  specifically stated in this Work Letter.

                           (8) All representations, warranties, covenants, and
                  conditions contained in this Work Letter shall survive the
                  completion of the Work
