located thereon from time to time (the "Leased Premises"):

     The first floor (excluding any common area lobbies) as depicted on Exhibit
     "A" attached hereto of the building located on the property commonly known
     as 24 South Second Street, in the City of St. Charles, Kane County,
     Illinois (the "Property") and the use of the sidewalks, if any, and other

shall and may peacefully and quietly have, hold and occupy the Premises free of
any interference from Landlord; subject, however, to each of the terms,
provisions and conditions of this Lease.

     Tenant acknowledges that the City of St. Charles (the "City") contemplates
demolition of the building directly to the east of the Leased Premises and
further plans to construct a parking structure on the property to the east.
Tenant acknowledges that the City has the right to proceed with the demolition
work and that the City's performance of such work shall not constitute in any
way a breach of Landlord's obligations under this Lease.  Landlord and Tenant
agree to work cooperatively with the City to permit the demolition and
construction work to be completed at no additional cost or expense to Tenant.
Landlord shall not be liable to Tenant in any way for the City's performance or
failure to perform the demolition or construction work.

ARTICLE 2. TERM.
           ----

     2.1  Term.  The term of this Lease shall commence on August 1, 1999.  That

be retroactive to August 1, 1999.

     This Lease shall have a Term of ten years and three months and shall end on

herein as the "Termination Date."

     2.2  Options to Extend.  On the condition that Tenant has faithfully

first give Landlord six (6) months' advanced written notice prior to the end of
the initial ten year Lease Term.  In order to exercise the second five year
option, Tenant must give Landlord six (6) months advance written notice prior to
the end of the first extended Lease Term.  In the event that Tenant fails to

within the time periods provided herein any of its obligations under this Lease,
then Tenant's options to extend shall likewise lapse and become null and void.
In the event that Tenant's options lapse, Tenant shall, at Landlord's request,
execute any and all documents necessary to evidence the lapse of said options.

shall relieve Tenant of any of its duties and obligations pursuant to this

that both Landlord's Work and Tenant's Work have been completed in substantial
compliance with the terms of this Lease and, as to Tenant's Work, the Plans and
Specifications.  At the walk-through, Landlord and Tenant shall create a written
"Punch List" of items to be completed.  The party responsible for a given Punch
List item agrees that the given Punch List item shall be completed as soon as is
reasonably practical following the walk-through but not later than 30 days after
the date of the walk-through, subject to force majeure.  If a party fails to
complete any item in the time period set forth herein, then after notice and
opportunity to cure as provided herein, the other party shall be entitled to
cause said items to be completed and assess the cost thereof to the other party.
With the exception of the items set forth on the Punch List, Tenant agrees to
accept the Leased Premises as being in good order and repair.

          F.   Force Majeure.  If Landlord or Tenant fails to timely perform any
               -------------
of the terms, covenants and conditions of this Lease on its part to be performed
and such failure is due in whole or in part to any strike, lockout, labor
trouble, civil disorder, inability to procure materials, failure of power,
restrictive governmental laws and regulations, riots, insurrections, war, fuel
shortages, accidents, casualties, acts of God, acts caused directly or
indirectly by the other party (or the other party's agents, employees,
contractors, licensees or invitees) or any other cause beyond the reasonable
control of Landlord or Tenant, as the case may be, then such party shall not be
deemed in default under this Lease as a result of such failure, and any time for
performance provided herein shall be extended by the period of delay resulting
from such cause.

     7.4  Landlord's and Tenant's Work.  The parties acknowledge that Landlord
          ----------------------------
is in discussion with the city of St. Charles regarding modifications to the
northerly facade of the building in order to permit the construction of a new
main entrance to the Leased Premises and windows on the northerly facade.  On
the condition that Landlord obtains City approval, Landlord agrees to

                                       9
<PAGE>

construct said new main entrance and windows in accordance with the standards
for Landlord's Work set forth above, and the cost thereof shall be shared by the
parties with the Tenant paying two-thirds of the cost and Landlord paying one-
third of the cost. The parties agree that Tenant's share of the cost shall not
exceed $75,000.00. Payment for the proportionate share of the costs shall be due
immediately upon completion of the work. Landlord shall furnish Tenant with a
separate bill and breakdown for expenses for this work.

     7.5  Maintenance and Repairs by Landlord.  During the term of this Lease,
          -----------------------------------
Landlord shall maintain, repair and replace, if necessary, the roof, the
exterior walls, the structural elements, and the exterior (exclusive of glass)
of the Leased Premises, all heating, air conditioning, ventilating, electrical,
mechanical, sprinkler and plumbing systems, equipment, machinery or fixtures
together with all pipes, conduits, ducts and drains servicing the Leased
Premises and other portions of the Property, and the remainder of the building
in which the Leased Premises are located including, without limitation, the
common areas of the building and the Property including, without limitation, the
sidewalks and landscaping, and keep the foregoing in a clean, sightly and
sanitary condition, free of snow, ice, debris, refuse, obstructions and hazards.
Landlord shall not, however, be responsible for maintaining or repairing any
window or window frames, doors, tracks and frames; pedestrian doors and frames;
exterior grills and ports for heating, ventilating and air conditioning units or
exhausts for inlets exclusively serving the Leased Premises.  Notwithstanding
the foregoing, Landlord shall have no obligation to perform any maintenance or
repairs wholly or partially caused by the negligence or fault of Tenant or any
of its agents, visitors or licensees, or by Tenant's breach of any provision of
this Lease.  Capitalized improvements to the Property shall not be deemed to be
common area maintenance.

     Tenant agrees, on a timely basis, to provide Landlord with written notice
of the need for any repairs or maintenance of the type described above.

     7.6  Maintenance and Repairs by Tenant.  Tenant, at its expense, shall
          ---------------------------------
maintain and repair the interior of the Leased Premises, and all heating, air
conditioning, ventilating, electrical, mechanical, sprinkler and plumbing
systems, equipment, machinery or fixtures exclusively servicing the Leased
Premises, together with all pipes, conduits, ducts and drains therefor.
Furthermore Tenant, at its expense, shall replace any broken glass in the
interior or exterior of the Leased Premises, and shall maintain and repair all
entryway doors to the Leased Premises.  Landlord shall assign to Tenant all
assignable manufacturers' warranties with respect to equipment and fixtures
installed in the Leased Premises.

     Tenant further agrees to keep the Leased Premises in good, tenantable,
sanitary, sightly and clean condition and to keep all lobbies and entryways
which are part of the Leased Premises clean and free from debris, refuse,
obstructions or hazardous conditions.  Tenant agrees to notify Landlord in the
event an excessive amount of snow accumulates on the roof of the Leased
Premises.

     Tenant shall be responsible for all maintenance or repairs wholly or
partially (to the extent of Tenant's part) caused by the negligence or fault of
Tenant or any of its agents, visitors or licensees, or by Tenant's breach of any
provision of this Agreement.

                                       10
<PAGE>

     If Tenant does not make the repairs or perform the maintenance required
hereunder in a prompt and adequate manner, then after notice to Tenant and
opportunity cure as provided herein, Landlord may make such repairs or perform
such maintenance and pay the costs thereof, and such costs shall be so much
Additional Rent which shall become immediately due and payable by Tenant to
Landlord.

     7.7  Future Drive-Up Teller Facility.  Landlord is currently in discussion
          -------------------------------
with the City of St. Charles in order to purchase or lease additional land to
the east of the Leased Premises to accommodate drive up teller lanes.  If the
City makes said land available for purchase or lease as a drive up, then
Landlord shall submit a proposal to Tenant containing additional lease terms
(including additional rent and construction costs responsibilities) in relation
thereto.  Tenant shall then decide whether or not to proceed with the
installation of the drive-up facility and to add such property to this Lease and
the Leased Premises described herein.  Nothing contained herein shall obligate
Landlord to provide or make available a drive-up facility at any time during
this Lease and the failure to provide same shall not constitute a breach of
Landlord's obligations under this Lease.

     7.8  Surrender of the Leased Premises.  Upon the termination of this Lease
          --------------------------------
whether by forfeiture, lapse of time, or otherwise, or upon the termination of
Tenant's rights to possession of the Leased Premises, Tenant will at once
surrender and deliver up to Landlord possession of the Leased Premises together
with all improvements thereon in good condition and repair, ordinary wear and
tear excepted.  Said improvements shall include all plumbing, lighting,
electrical, heating, cooling and ventilating fixtures and equipment and other
articles of personal property used in the operation of the Leased Premises (as
distinguished from the Trade Fixtures which are used in the operation of
Tenant's business).  All additions, hardware, non-trade fixtures and
improvements to the Leased Premises shall become Landlord's property and shall
remain upon the Leased Premises, without compensation to Tenant, unless Landlord
requests their removal in writing at the time of approval of installation (if
applicable).  Upon termination of this Lease, the Tenant agrees to deliver to
Landlord all of the keys to the Leased Premises.

     The Tenant may remove Tenant's Trade Fixtures from the Leased Premises
provided, however, that Tenant shall repair any injury to or damage to the
Leased Premises caused by the removal of its Trade Fixtures.  In the event that
Tenant fails to remove its Trade Fixtures, Landlord may, at its option, remove
the same and deliver the same to any other place of business of Tenant or
warehouse the same, and Tenant shall be responsible for paying the cost of said
removal, including the cost of repairing any damage to the Leased Premises
resulting from such removal, delivery and warehousing, to Landlord on demand.

     7.9  Holding Over.  Any holding over by Tenant of the Leased Premises after
          ------------
the expiration of this Lease shall operate and be construed to be a tenancy from
month to month only at the same monthly rate of rent and other charges payable
hereunder for the Lease Term.  If the parties are not then engaged in bona fide
negotiations to renew or to extend the Lease, and if Tenant continues to hold
over after a written demand by Landlord for possession at the expiration of the
Lease Term or after termination by either party of a month-to-month tenancy
created pursuant to this paragraph, then Tenant shall pay Monthly Rent at a rate
equal to double the rate of Monthly Rent for the month immediately prior to the
hold over period.  Nothing contained in this section shall be

                                       11
<PAGE>

construed to give Tenant a right to hold over at any time, and Landlord may
exercise any and all remedies at law or in equity to recover possession of the
Leased Premises.

     7.10 Mechanic's Liens.  Tenant will not permit any mechanic's lien or
          ----------------
liens (other than those caused by the acts of Landlord) to be placed upon the
Leased Premises or the Real Property or any building or improvement thereon
during the term hereof, and in case of filing of any such lien, Tenant shall
promptly pay for or cause a title company to bond over same. Tenant shall have
the right to contest any such lien provided that Tenant pursues such contest
diligently, such contest does not result in the forfeiture of the Property, and
Tenant posts adequate security with a title company or Landlord therefor. If
Tenant fails promptly to pay for or bond over any such lien, Landlord, at its
option, after notice to Tenant and opportunity to cure as provided herein, may
pay for said lien, and any amounts so paid, including expenses and interest,
shall become so much Additional Rent hereunder due from Tenant to Landlord and
shall be paid to Landlord immediately.

     7.11 Alterations.  Tenant shall not make any material changes or
          -----------
structural alterations to the Leased Premises, without first obtaining the
Landlord's written consent, which consent shall not be unreasonably withheld,
delayed or conditioned. Upon the completion of any such changes or alterations,
Tenant shall provide Landlord with such documents as Landlord may require
(including, without limitation, Sworn Contractor's Statements and supporting
lien waivers) evidencing payment in full for such work. Any such changes or
alterations must be made in accordance with applicable building codes or other
governmental regulations.

ARTICLE 8. INSURANCE.
           ---------

     As Additional Rent, Tenant shall procure and maintain, during the term of
this Lease, policies of insurance at Tenant's own cost and expense insuring the
following:

          1.  Landlord and Tenant from all claims, demands or actions for injury
     to or death of any person in an amount of not less than $3,000,000.00, for
     injury to or death of more than one person in any one occurrence in an
     amount of not less than $3,000,000.00, and for damage to property in an
     amount of not less then $1,000,000.00 made by, or on behalf of, any person
     or persons, firm or corporation arising from, related to, or connected with
     Tenant's use or occupancy of the Leased Premises.

          2.  Landlord and Tenant from all worker's compensation claims;

          3.  All contents, and all of Tenant's personal property and Trade
     Fixtures, machinery, equipment and furniture and furnishings contained in
     the Leased Premises to the extent of at least ninety percent (90%) of their
     replacement cost under the standard fire and extended coverage insurance,
     including without limitation to, vandalism and malicious mischief and
     sprinkler leakage endorsements.

     The aforesaid insurance shall be issued by companies and in form,
substance, and amount (where not stated above) reasonably satisfactory to
Landlord and any mortgagee of Landlord, and shall contain standard mortgage
clauses satisfactory to Landlord's mortgagee.  Each such policy shall name
Landlord and its individual members as additional insureds.  The aforesaid
insurance

                                       12
<PAGE>

shall not be subject to cancellation except after at least thirty (30) days
prior written notice to Landlord and any mortgagee of Landlord. Duplicate
original policies (or certificates thereof satisfactory to Landlord) together
with satisfactory evidence of payment of the premiums thereon shall be deposited
with Landlord at the Commencement Date and renewals thereof not less than thirty
(30) days prior to the end of the term of such coverage. If Tenant fails to pay
the premiums on any of said insurance policies, then after ten (10) days' notice
to Tenant and opportunity to cure, Landlord may at its option pay said premiums,
and any payments made by Landlord shall constitute Additional Rent which shall
become immediately due and payable.

ARTICLE 9.  INDEMNITY FOR ACCIDENTS.
            -----------------------

     Tenant covenants and agrees that it will protect and save and keep the
Landlord forever harmless and indemnified against any penalty or damages or
charges imposed for any violation of any laws or ordinances, or any civil claim
with respect to the Leased Premises which occurs during the Lease Term or any
holdover period, whether occasioned by the neglect of Tenant or those holding
under Tenant, but not for any actions or inactions of the Landlord or its
agents, servants, employees, contractors, licensees, guests, invitees or other
tenants.  Pursuant to said obligation, Tenant will at all times protect,
indemnify and save and keep harmless the Landlord against and from any and all
loss, costs, damage or expense, including reasonable attorney's fees, arising
out of and from any accident or other occurrence on or about the Leased Premises
causing injury to any person or property whomsoever or whatsoever and will
protect, indemnify, and save and keep harmless the Landlord against and from any
and all claims and against and from any and all loss, costs, damage or expense
arising out of any failure of Tenant in any respect to comply with and perform
all of the requirements and provisions hereof.

     Likewise, Landlord covenants and agrees that it will protect and save
Tenant forever harmless and indemnified against any penalty or damages or
charges imposed as a result of any violation of any laws or ordinances or any
civil claim with respect to the Property (other than those with respect to the
Leased Premises), whether occasioned by Landlord's or its agents', servants',
employees', contractors', guests', or invitees' (excluding other tenants')
negligent or unlawful conduct or intentional acts or omissions other than such
guests' or invitees' criminal acts.

ARTICLE 10. FIRE AND CASUALTY.
            -----------------

     In the event that the Leased Premises shall be rendered substantially
untenantable or unsuitable for Tenant's purposes during the term of this Lease
by fire or other casualty, Landlord at its option may terminate this Lease
effective as of the date of such casualty or Landlord may elect to repair the
Leased Premises.  If Landlord elects to repair this Lease will remain in effect
provided that such repairs are promptly commenced, diligently pursued and
completed in a timely manner but not more than 180 days after the date of the
fire or other casualty.  If more than 40% of the Leased Premises is rendered
substantially untenantable or unsuitable by fire or casualty and Landlord does
not complete the repair and restoration thereof within said 180 days, then
Tenant may terminate this Lease effective as of the date of such fire or
casualty.  If this Lease is terminated by reason of fire or casualty as herein
specified, monthly Base Rent and Additional Rent shall be apportioned and paid
to the day of such fire or other casualty.  During any time period that the
Leased Premises is

                                       13
<PAGE>

untenantable, rent will abate if the cause of the casualty is not the result of
Tenant's negligent acts or omissions.

     Whenever (a) any loss, cost, damage or expense resulting from fire,
exploding or any other casualty or occurrence is incurred by either of the
parties to this Lease in connection with the Leased Premises, and (b) such party
is then covered in whole or in part by insurance with respect to such loss,
cost, damage or expense, then the party so insured hereby releases the other
party from any liability it may have on account of such loss, cost, damage or
expense to the extent of any amount recovered by reason of such insurance and
waives any right of subrogation which might otherwise exist in or accrue to any
person on account thereof, provided that such release of liability and waiver of
the right of subrogation shall not be operative in any case where the effect
thereof is to invalidate such insurance overage or increase the cost thereof.

ARTICLE 11. MISCELLANEOUS PROVISIONS.
            ------------------------

     11.1 Subordination.  This Lease is subordinate and shall be subordinate to
          -------------
any and all mortgages which may now or hereafter affect the Leased Premises.

     11.2 Assignment and Subletting.  Tenant shall not, without Landlord's prior
          -------------------------
written consent (which consent shall not be unreasonably withheld, delayed or
conditioned), assign, convey or mortgage this Lease or any interest in the
Leased Premises or sublet any and all or part of the Leased Premises.
Notwithstanding anything herein to the contrary, Tenant shall be permitted to
assign this Lease in whole, but not in part, to any parent, subsidiary or other
entity affiliated with Tenant or to any survivor of any merger or consolidation
with or reorganization of Tenant.

     11.3 Abandonment and Reletting.  If Tenant shall abandon or vacate the
          -------------------------
Leased Premises, or if Tenant's right to occupy the Leased Premises shall be
terminated by Landlord by reason of Tenant's breach of any of the covenants
herein, the same may be relet by Landlord (acting reasonably) for such rent and
upon such terms as Landlord may deem fit, and if a sufficient sum shall not thus
be realized monthly, after paying expenses of such reletting and collecting to
satisfy the rent hereby reserved, Tenant agrees to satisfy and pay all
deficiencies monthly during the remaining term of this Lease.

     11.4 Rights Reserved to Landlord.  During the term of this Lease the
          ---------------------------
Landlord shall possess, the following rights:

          1.  Upon reasonable notice to Tenant, to inspect the Leased Premises
     and to make repairs, additions or alterations to the Leased Premises
     required by the terms of this Lease;

          2.  In the event of an emergency, to enter the Leased Premises without
     notice to Tenant and to take any reasonable steps necessary in order to
     eliminate said emergency.

          3.  During the last six months of the Lease Term (if not renewed or
     extended by Tenant), to place and maintain a "For Rent" sign on the Leased
     Premises; and

                                       14
<PAGE>

          4.  To show the Leased Premises to prospective purchasers, mortgagees
     or other persons having a legitimate interest in viewing the same and to
     place and maintain a "For Sale" sign on the Property.

          5.  To install an elevator in the west lobby area, at Landlord's
     expense if Landlord elects to do so.

     11.5 Default.  In the event that Tenant defaults on any of the covenants or
          -------
provisions contained in this Lease, Landlord shall give Tenant written notice of
such default and 10 days' opportunity to cure in the case of a monetary default
or 30 days opportunity to cure in the case of a non-monetary default, provided
that if such default cannot reasonably be cured within a 30 day period and if
Tenant has commenced and is diligently proceeding to cure such default, Tenant
shall be given a reasonable period of time to cure such default.  If any such
default remains uncured after the aforesaid time period, then Landlord at its
election may terminate this Lease or terminate Tenant's right to possession
only, without terminating the Lease.  Upon termination of this Lease or Tenant's
right of possession, Landlord may re-enter the Leased Premises without process
of law and remove all persons, fixtures, and property therefrom, and Landlord
shall not be liable for any damages resulting therefrom.  Upon the termination
of the Lease, or upon termination of Tenant's right of possession without
termination of the Lease, the Tenant shall surrender possession and vacate the
Leased Premises immediately, and deliver possession thereof to the Landlord, and
hereby grants to Landlord the full and free right to enter upon the Leased
Premises and to repossess the Leased Premises as Landlord's former estate and to
expel or remove the Tenant and any others who may be occupying or within the
Leased Premises without relinquishing the Landlord's rights to rent or any other
right given to Landlord hereunder or by operation of law.

     In the event that Tenant breaches any of the provisions or covenants of
this Lease, Landlord shall be entitled to recover as damages, all rent and other
sums due and payable by Tenant as well as the cost of performing any covenants
to be performed by Tenant.  Furthermore, Landlord shall be entitled to recover
any court costs or attorney's fees incurred as a result of Tenant's breach.

     The rights and remedies of Landlord under this Lease are cumulative.  The
exercise or use of any one or more thereof shall not bar the Landlord from
exercise or use of any other right or remedy provided herein or otherwise
provided by law, nor shall the exercise nor the use of any right or remedy by
Landlord waive any other right or remedy.

     11.6 Successors.  All covenants and agreements contained herein shall be
          ----------
binding upon and inure to, the respective rights of Landlord or Tenant or their
successors, heirs, executors, administrators or assigns.

     11.7 Severability.  Wherever possible, each provision of this Lease will be
          ------------
interpreted in a manner so as to be effective and valid under applicable law,
but if any provision of this Lease shall be prohibited by or be held invalid
under applicable law, such provision shall be ineffective to the extent of such
prohibition or invalidity, without invalidating the remainder of such provisions
or the remaining provisions of this Lease.

acknowledge and deliver to Landlord in a form reasonably satisfactory to

           ----------
Lease, to be kept and performed by either party shall in any manner be altered,
waived, modified, changed or abandoned except by a written instrument, duly

     B. The Prime Lease covers certain leased space in the office building (the
"Building") located at 1401 South Brentwood Boulevard, St. Louis, Missouri
63144. The leased area described in the Prime Lease is referred to herein as the
"Leased Premises."

     C. Subtenant desires to lease a portion of the Leased Premises on the terms
and subject to the conditions below.

     NOW, THEREFORE, in consideration of the foregoing recitals, the covenants
and agreements herein and other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, Sublandlord and Subtenant hereby
agree as follows:

     1. Prime Lease.

          1.1 Sublandlord and Subtenant agree that this Sublease is entered into
     to create a sublease under the Prime Lease. The Prime Lease is attached
     hereto as Exhibit A and by this reference incorporated herein. Subtenant
     acknowledges having received and reviewed the Prime Lease. Notwithstanding
     anything to the contrary in this Sublease, any termination of the Prime
     Lease will cause this Sublease to be terminated as of the same time and
     date that the Prime Lease is terminated, subject to Section 15.4 of this
     Sublease, which provides for the survival of certain claims in the event
     the Sublease is terminated, and any unearned Rent paid in advance shall be
     refunded to Subtenant; provided, however that if such termination is the
     result of a breach of Subtenant's obligations hereunder, then Sublandlord
     shall have the right to retain such amount until such time that the damages
     from such breach have been ascertained, at which time such amount may be
     applied by Sublandlord to the payment of such damages without limiting the
     amount Sublandlord will be entitled to recover as a result of such breach.

          1.2 Sublandlord and Subtenant agree that this Sublease is not
     effective until such time as Primary Landlord has consented in writing to
     this Sublease, such consent to be evidenced by means of Primary Landlord's
     execution and delivery of a counterpart of this Sublease in the space
     provided below. Until such written consent has been obtained, either party
     shall have the right to terminate this Sublease upon the delivery of
     written notice thereof to the other party and Primary Landlord.
<PAGE>

     2. Subleased Premises. Sublandlord agrees to lease to Subtenant certain
premises located on the 1st and 2nd floors of the Building, consisting of
approximately 12,378 total rentable square feet of floor area, with
approximately 3,026 rentable square feet on the 1st floor and approximately
9,352 rentable square feet on the 2nd floor, as more Rally described on Exhibit
B attached hereto and by this reference incorporated herein (the "Subleased
Premises"), together with the nonexclusive right and license during the Sublease
Term (as defined in Section 4 below) to use any areas required to access and use
the drive-up banking facilities and lanes, any areas required to access and use
the automated teller machines or space therefor and the after-hours depository
area, and any areas of the Leased Premises required for ingress and egress to
and from the Subleased Premises by Subtenant and its employees, agents and
invitees. Notwithstanding the fact that the foregoing use is nonexclusive,
Subtenant's access to such locations and/or facilities shall not be materially
or unreasonably restricted. Subtenant and its employees, agents and invitees
shall have the exclusive right and license during the Sublease Term to use any
automated teller machines or space therefor, the after-hours depository
facilities outside the Building and the drive-up banking facilities; provided,
however that the exclusive right shall not apply to drive-up lanes at those
locations and/or facilities. Subtenant must obtain Primary Landlord's prior
written approval before placing any automated teller or other banking facilities
on any part of the Leased Premises.

     3. Compliance with Terms of Prime Lease.

          3.1 Subtenant agrees that this Sublease is subject and subordinate to
     all of the terms, conditions, and provisions of the Prime Lease and the
     exhibits thereto, including without limitation the Building Rules set forth
     on Exhibit D thereto, and that Subtenant will not violate or permit the
     violation of, and at its cost shall cause the Subleased Premises and
     Subtenant's activities on or about the Subleased Premises to be in
     compliance with the Prime Lease. Subtenant will cooperate with Sublandlord
     and assist Sublandlord in complying with the terms of the Prime Lease, as
     it applies to the Subleased Premises and Subtenant's use of common areas.
     In the event of a conflict between any term, condition or provision of the
     Prime Lease and this Sublease, the terms and provisions of this Sublease
     shall control in all controversies arising between Sublandlord and
     Subtenant, and the terms and provisions of the Prime Lease shall control in
     all controversies arising between Primary Landlord and Sublandlord or
     Subtenant, except as the parties have agreed in this Sublease.

          3.2 In the event that Subtenant or any agent, employee, officer, or
     invitee of Subtenant takes, threatens to take, or fails to take any action
     which will result in the breach or violation of the Prime Lease with
     reference to the Subleased Premises or use of the common areas, Subtandlord
     shall be entitled to injunctive or such other appropriate equitable relief
     as may be necessary to prevent any violation or breach of the Prime Lease
     by Subtenant or its agents employees, officers or invitees, together with
     all of Sublandlord's damages occasioned thereby, it being agreed by the
     parties that any breach of the Prime Lease would cause irreparable harm to
     Sublandlord.

          3.3 If any obligation of Sublandlord under this Sublease is to be
     performed by Primary Landlord under the Prime Lease and Primary Landlord
     fails to perform such obligation, then Sublandlord shall have no liability
     to Subtenant hereunder as a result of such failure, except that Sublandlord
     agrees to use commercially reasonable efforts to cause Primary Landlord to
     perform such obligation. For example, and not by way of limitation, if any
     service to be provided under this Sublease is to be provided by Primary
     Landlord under the Prime Lease and Primary Landlord fails to provide such
     service, then Sublandlord shall have no liability to Subtenant for the
     failure of such service to have been

                                      -2-
<PAGE>

     provided. In such event, however, Sublandlord agrees to use commercially
     reasonable efforts to cause Primary Landlord to provide such service.

          3.4 If any consent or approval is required to be obtained by
     Sublandlord under the provisions of this Sublease prior to the taking of
     any action on the part of Subtenant, and the Prime Lease contains a
     comparable provision requiring the consent of the Primary Landlord, then
     any consent by Sublandlord to the taking of such proposed action by the
     Subtenant shall not be effective until such time, if at all, that Primary
     Landlord consents to the taking of such action.

     4. Sublease Term.

          4.1 Subject to Sections 1.1,36 and 37 of this Sublease, the term of
     this Sublease (the "Sublease Term") shall commence on December 13, 1999
     (the "Commencement Date") and shall expire at 11:59 p.m. (St. Louis time)
     on February 4, 2009 (the "Expiration Date").

          4.2 Subject to Sections 1.1, 36 and 37 of this Sublease, this
     Sublease, and the Sublease Term, shall commence on the Commencement Date
     and shall terminate and expire on the Expiration Date without the necessity
     of any termination notice from either Sublandlord or Subtenant.

     5. Monthly Base Rent Subtenant shall pay monthly base rent ("Monthly Base
Rent") in advance to Sublandlord on the first (1st) day of each month during the
Initial Term as follows:

          5.1 The "Rent Commencement Date" is hereby defined to mean January 1,
     2000. During the period commencing on the Rent Commencement Date through
     and including the Expiration Date, Subtenant shall be obligated to pay
     Monthly Base Rent on the first day of each month, without offset or
     deduction for any reason. The amount of each such monthly payment shall be
     as follows:

          January 1, 2000 - December 31, 2000                      $20,630.00
          January 1, 2001 - December 31, 2001                      $24,240.25
          January 1, 2002 - December 31, 2002                      $24,756.00
          January 1, 2003 - December 31, 2003                      $25,271.75
          January 1, 2004 - December 31, 2004                      $25,787.50
          January 1, 2005 - December 31, 2005                      $26,303.25
          January 1, 2006 - December 31, 2006                      $26,819.00
          January 1, 2007 - December 31, 2007                      $27,334.75
          January 1, 2008 - December 31, 2008                      $27,850.50
          January 1, 2009 - February 4,  2009                      $28,882.00

          5.2 Monthly Base Rent for any partial month shall be prorated over the
     actual number of days in such month that the Sublease Term is then in
     effect, and shall be paid on the first (1st) day of such partial month. All
     amounts required to be paid by Subtenant under this Sublease which do not
     constitute Monthly Base Rent shall constitute "additional rent" due
     hereunder. The term "Rent" shall mean the Monthly Base Rent and all
     additional rent.

     6. Building Operating Expense Reimbursement.

          6.1 Under the Prime Lease, Sublandlord is obligated to reimburse
     Landlord for Subtenant's pro rata share of increases in "Expenses" in
     excess of the "Expense Stop Amount" (as such capitalized terms are defined
     in the Prime Lease). For purposes of this Sublease, the term "Base Year"

                                      -3-
<PAGE>

     shall mean 2000. For purposes of this Section 6, Subtenant's pro rata share
     ("Subtenant's Percentage") shall be 7.25%. The parties agree that the
     intention of this Section 6 is to obligate Subtenant to pay its pro rata
     share of Expenses which are in excess of Expenses for the Base Year.

          6.2 In addition to Monthly Base Rent, Subtenant shall pay to
     Sublandlord additional rent with respect to each calendar year during the
     Sublease Term in accordance with the following provisions:

               (a) If Expenses during any calendar year after the Base Year
          exceed Expenses for the Base Year (such excess being referred to
          herein as "Excess Expenses"), then Subtenant shall pay to Sublandlord,
          as additional rent for each such calendar year, an amount equal to
          Subtenant's Percentage of such Excess Expenses. Expenses shall be
          determined by Primary Landlord in accordance with the provisions of
          the Prime Lease.

               (b) Sublandlord shall deliver to Subtenant written notice of its
          estimate of Excess Expenses for the upcoming calendar year.
          Sublandlord shall have the right to rely on estimates thereof prepared
          by Primary Landlord. On the first day of each and every calendar month
          commencing after the receipt of each such estimate and prior to the
          receipt of the next annual estimate of Excess Expenses, Subtenant
          shall pay to Sublandlord one-twelfth (1/12) of Subtenant's Percentage
          of Excess Expenses based upon such estimate. Such estimated payments
          shall be due on the same date as are the installments of Monthly Base
          Rent. Subtenant's Percentage of Excess Expenses for each calendar year
          of the Sublease Term shall be deemed to be additional rent becoming
          due under this Sublease and Subtenant's obligation to pay Subtenant's
          Percentage of Excess Expenses for the Sublease Term shall survive the
          expiration or termination of this Sublease.

               (c) As soon as reasonably possible after the expiration of each
          calendar year during the Sublease Term, Sublandlord will furnish to
          Subtenant a statement showing the Expenses for the expired calendar
          year and the estimated amount of Expenses to be paid during the next
          calendar year, such statement to be in the same form as the statement
          provided to Sublandlord by Primary Landlord. If Subtenant's Percentage
          of Excess Expenses for any calendar year exceeds the payment on
          account thereof made by Subtenant, Subtenant shall pay to Sublandlord
          the deficiency within fifteen (15) days after the receipt of a
          statement therefor. Such obligation on the part of Subtenant shall
          survive any vacation of the Subleased Premises by Subtenant. If any
          such statement shows that the payments made by Subtenant on account of
          Excess Expenses exceeded the amount then payable by Subtenant, then
          Sublandlord shall apply such excess to future payments of additional
          rent or, in the event Subtenant has vacated the Subleased Premises in
          accordance with its rights hereunder, pay the amount of such excess to
          Subtenant. In no event shall any rent adjustment result in a decrease
          of Monthly Base Rent.

               (d) If Expenses for any calendar year are revised after a
          statement thereof has been delivered to Subtenant, then the parties
          agree to make such adjustments as may be necessary based upon the
          revised amount of Expenses.

               (e) Excess Expenses for any partial calendar year at the end of
          the Sublease Term shall be prorated.

     7. Security Deposit. Subtenant, concurrently with signing this Sublease,
shall pay to Sublandlord a Security Deposit in the amount of $28,882.00 to be
held to guarantee the faithful performance by Subtenant of all of Subtenant's
obligations under this Sublease. The Security Deposit may be commingled with
Sublandlord's other funds and any interest or other income earned thereon

                                      -4-
<PAGE>

shall be the property of Sublandlord. If Subtenant defaults with respect to any
provision of this Sublease, Sublandlord may expend the whole or any part of the
Security Deposit for the payment of any amount which Sublandlord may expend by
reason of such default. If any portion or all of the Security Deposit is so
used, Subtenant shall, within ten (10) days after demand therefor, deposit cash
with Sublandlord in an amount sufficient to restore the Security Deposit to its
original amount and failure to do so shall be a breach of this Sublease.
Provided no event of default has occurred and is continuing under this Sublease
on the later of (a) the first anniversary of the Commencement Date, or (b) the
expiration of all contingencies and termination rights under this Sublease (as
set forth in Sections 36 and 37), Sublandlord shall return the Security Deposit
to Subtenant within fifteen (15) days after Sublandlord's receipt of notice from
Subtenant that each of the foregoing conditions have been met, together with any
evidence reasonably required by Sublandlord that all contingencies have been
satisfied and all termination rights have expired. In the event of a transfer of
Sublandlord's interest in the Building, Sublandlord may pay over the Security
Deposit to Sublandlord's transferee to be held under the terms of this Sublease
and Sublandlord shall be released from all liability for the return of the
Security Deposit. Under no circumstances shall Subtenant have the right to
direct that the Security Deposit be applied to the payment of Rent.

     8. Use of Subleased Premises. Subtenant shall use and occupy the Subleased
Premises only as a full-service banking facility, providing any services that
may be provided by a commercial bank under federal and Missouri laws, and for
general office purposes, and for no other use or purpose whatsoever without the
express prior written consent of Sublandlord and Primary Landlord.

     9. Alterations and Improvements.

          (a) The Subleased Premises are being subleased in an "AS IS - WHERE
     IS" condition, unless expressly provided otherwise herein; Sublandlord
     shall have no obligation to perform any alterations to ready the Subleased
     Premises for Subtenant's occupancy. Sublandlord makes and has made no
     representations or warranties with respect to the condition of the
     Subleased Premises or as to its suitability for the use or uses
     contemplated by Subtenant. Subtenant's occupancy of the Subleased Premises
     shall constitute Subtenant's acceptance of the condition of the same and
     its agreement that the Subleased Premises are in good condition. Subtenant
     shall, at its cost and expense, install its own telephone and computer
     equipment systems.

          (b) Except as provided in this Sublease, any alterations, additions,
     changes or improvements to the Subleased Premises not expressly described
     herein shall be made only with the prior written consent of Primary
     Landlord and notice of the same to Sublandlord as provided herein. In the
     event Primary Landlord consents to the making of alterations, additions,
     changes or improvements to the Subleased Premises, Sublandlord shall be
     furnished with such evidence of Primary Landlord's consent as Sublandlord
     shall require at least fifteen (15) days prior to the commencement of such
     work. Prior to the commencement of any work, Primary Landlord and
     Sublandlord shall be furnished with copies of all plans and specifications,
     a budget listing by line item the cost of the work to be done, and evidence
     of the provision of performance bonds, if required by Primary Landlord. The
     work necessary to make the change(s) shall be done at Subtenant's expense
     by employees or contractors hired by Primary Landlord and approved by
     Subtenant. Subtenant agrees to pay Primary Landlord or its agent,
     lnsignia/ESG, Inc., directly for any work to be performed prior to the
     commencement of any work and pay all construction supervision fees charged
     by Primary Landlord. Subtenant also agrees to reimburse Sublandlord for any
     construction supervision fees charged by Primary Landlord to Sublandlord.
     In no event shall any lien be established against the Subleased Premises or
     the Building. In the event the actual cost of the alterations, plus the
     construction supervision fee, are less than the amount paid to

                                      -5-
<PAGE>

     Primary Landlord by Subtenant as required in this subsection (b), Primary
     Landlord shall pay the difference to Subtenant within thirty (30) days
     after completion of the alterations.

          (c) Upon Subtenant's receipt of all Regulatory Approvals (as defined
     in Section 16.4 of this Sublease), satisfaction of any other contingencies
     set forth in this Sublease, expiration of all termination rights set forth
     in this Sublease (as such contingencies and termination rights are set
     forth in Sections 36 and 37 of this Sublease), and delivery of notice of
     the same to Sublandlord and Primary Landlord (together with such evidence
     of the same as Sublandlord or Primary Landlord may require), Sublandlord
     will pay to Subtenant up to $123,780.00 (the "Improvement Allowance") in
     accordance with Section 9(b) of this Sublease and all other provisions of
     this Section 9. Subtenant agrees that such Improvement Allowance will be
     used for Subtenant's improvement of the Subleased Premises (including
     without limitation, for the preparation of any architectural drawings
     created in connection with such improvements). Prior to the commencement of
     any improvements, the name of the selected general contractor, all
     architectural drawings, plans and specifications, the construction
     schedule, a budget showing by line item the cost of the construction and
     evidence of Primary Landlord's consent to the improvements as required in
     this Section 9 must be furnished to Sublandlord. The Improvement Allowance
     will be paid to Subtenant upon Sublandlord's receipt of sufficient evidence
     as required by Sublandlord of completion of the improvements, including
     without limitation copies of invoices, evidence that the same have been
     paid, and lien waivers from contractors and suppliers; provided, however,
     that in no event shall Sublandlord be obligated to pay more than the amount
     of the Improvement Allowance for any and all work and that Subtenant shall
     pay all costs in excess of the Improvement Allowance. If Subtenant does not
     intend to utilize all or a part of the Improvement Allowance and so
     notifies Sublandlord, then any unused amount of the Improvement Allowance
     shall be credited against Subtenant's obligation to pay Monthly Base Rent
     hereunder from the first day of the month after Sublandlord's receipt of
     the notice until the entire unused amount of the Improvement Allowance has
     been applied and credited to the Monthly Base Rent payments. If Subtenant
     fails to fully utilize the Improvement Allowance during the Sublease Term,
     then any unused amount of the Improvement Allowance shall be credited
     against Subtenant's obligation to pay Monthly Base Rent hereunder and shall
     be refunded by Sublandlord to Subtenant within fifteen (15) days after the
     Expiration Date. Any and all improvements or alterations to be made by
     Subtenant in connection therewith shall be subject to the provisions of
     this Sublease. Nothing in the foregoing shall relieve Subtenant from any of
     its other obligations under this Sublease.

          (d) Primary Landlord covenants and agrees that no act or omission of
     Primary Landlord or any contractor, subcontractor or supplier arising out
     of any construction performed by or at the direction of Primary Landlord
     with respect to the Subleased Premises, including without limitation, the
     filing of any lien against the Leased Premises or any part thereof, shall
     cause or create a default under the Prime Lease (as such term is defined
     therein).

     10. Repairs. During the continuance of this Sublease, Subtenant shall keep
the Subleased Premises and appurtenances in good order and repair; shall keep
the Subleased Premises and appurtenances in a wholesome condition without charge
or expense to Sublandlord; shall pay for all damages to the Building as well as
damages to the tenants or occupants thereof caused by any waste, misuse or
neglect of said Subleased Premises, its apparatus or appurtenances; and shall
not make nor allow to be made any change, alteration or addition, in, upon or to
said Subleased Premises without the written consent of Sublandlord and Primary
Landlord for that purpose first had and obtained. Upon the expiration or earlier
termination of Subtenant's right to possession of the Subleased Premises,
Subtenant shall surrender to Sublandlord the Subleased Premises in as good
condition and repair as on the Commencement Date, reasonable wear and tear
excepted, and all alterations, fixtures (other than

                                      -6-
<PAGE>

Subtenant's trade fixtures) and improvements shall remain with, and become the
property of, Sublandlord unless Subtenant is directed by Sublandlord in writing
to remove the same prior to the expiration or termination of Subtenant's right
to possession of the Subleased Premises. If Subtenant fails to leave the
Subleased Premises in such condition, then Sublandlord shall have the right to
repair and restore the same to such condition and Subtenant shall reimburse
Sublandlord for the cost thereof plus fifteen percent (15%).

     11. Furniture and Fixtures.

          11.1 All trade fixtures attached to the Subleased Premises on the date
     hereof, including without limitation, the teller counters and related
     equipment, vaults, safe deposit boxes, facilities and marked keys for each
     box, after-hour drops for deposits, kiosks, vacuum systems and related
     equipment (but excluding the automated teller machine and the security
     systems), and all furniture and equipment shown on Exhibit C attached
     hereto and made a part hereof (such furniture and equipment, except for any
     furniture or equipment located in the drive-up teller area, are
     collectively referred to as the "Personal Property"), shall be deemed to be
     a part of the property subleased by or licensed to Subtenant hereunder. As
     of the date of this Sublease, to the knowledge of Sublandlord, such trade
     fixtures, related equipment and Personal Property are in good working order
     and repair. Subtenant shall be liable for and shall pay before delinquency,
     taxes leveled against the Personal Property and any other personal property
     or trade fixtures placed by Subtenant in the Subleased Premises. If any
     such taxes are levied against Sublandlord, whether directly or indirectly,
     or the Subleased Premises, or if the assessed value of the Building is
     increased by the inclusion of such personal property or trade fixtures,
     upon written notice from Sublandlord, Subtenant shall pay to Sublandlord
     the amount of the taxes based upon the increased assessments. Subtenant
     shall have the right, at its sole cost, to replace, remove or eliminate any
     items of the Personal Property.

          11.2 Provided no event of default has occurred and is continuing as of
     the Expiration Date, and further provided that Subtenant has delivered to
     Sublandlord a notice that it desires to purchase the Personal Property (as
     shown on Exhibit C to this Sublease), on the Expiration Date, ownership of
     such Personal Property shall immediately and automatically transfer to
     Subtenant and this Sublease shall be deemed a bill of sale evidencing
     Sublandlord's agreement, as of the date of this Sublease, to sell the
     Personal Property to Subtenant, subject to the terms of this Sublease.
     Sublandlord hereby represents and warrants that it has good right and
     lawful authority to sell all of its right, title and interest in and to the
     Personal Property and that it will not assign or transfer such rights prior
     to the Expiration Date. SUBLANDLORD MAKES NO REPRESENTATION OR WARRANTY
     (EXPRESS OR IMPLIED) AS TO THE CONDITION OF THE PERSONAL PROPERTY,
     INCLUDING, WITHOUT LIMITATION, ANY REPRESENTATION OR WARRANTY OF
     MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. SUBLANDLORD AGREES TO
     SELL THE PERSONAL PROPERTY "AS IS, WHERE IS" THE WARRANTIES OF
     MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE ARE HEREBY EXPRESSLY
     DISCLAIMED.

     12. Insurance.

          12.1 Subtenant shall, at its own expense, provide and keep in force,
     comprehensive public liability insurance for the benefit of Sublandlord and
     Subtenant jointly against liability for bodily injury, death, property
     damage and contractual liability with a combined single limit of not less
     than Five Million and 00/100 Dollars ($5,000,000.00), such limit to be for
     any amount greater as may be reasonably indicated by circumstances from
     time to time and existing.

                                      -7-

          12.2 Subtenant shall maintain in full force and effect on all fixtures
     and equipment in the Subleased Premises a policy or policies of fire and
     extended coverage insurance with standard coverage, vandalism, malicious
     mischief, special extended perils (all risk), sprinkler damage and
     subrogation waiver endorsements to the extent of one hundred percent (100%)
     of their insurable value during the term of this Sublease. Until Subtenant
     surrenders possession of the Subleased Premises to Sublandlord, Subtenant
     shall retain all risk of loss with respect to any of Subtenant's property
     located at the Subleased Premises.

          12.3 Subtenant shall maintain in form and amount reasonably acceptable
     to Sublandlord all workers' compensation insurance or similar insurance as
     may be required under the laws of the state in which the Subleased Premises
     is located in respect to the operation, maintenance, protection, repair,
     alteration, or reconstruction of the Subleased Premises or any part thereof
     which may be undertaken by Subtenant pursuant to the terms of this
     Sublease.

          12.4 Subtenant shall maintain such other coverages as may be required
     after the date hereof under or pursuant to the Prime Lease, each in the
     standard form generally used in the State of Missouri and by a company
     reasonably acceptable to Primary Landlord. The amount of any insurance
     coverages required to be maintained by Subtenant are subject to increase
     upon any increase in the coverages required under the Prime Lease.

          12.5 Primary Landlord and Sublandlord shall be named as additional
     insureds under all policies of insurance required by this Sublease. All
     insurance policies shall be primary and non-contributing with any insurance
     carried by Sublandlord or Primary Landlord. The insurance required
     hereunder shall be in companies that are reasonably acceptable to
     Sublandlord and Primary Landlord. Not less than ten (10) days prior to the
     commencement of the Sublease Term, and thereafter, upon Sublandlord's
     request, from time to time, Subtenant shall deliver to Sublandlord evidence
     of the insurance required to be carried by Subtenant on ACORD form 27, and
     each such certificate and insurance policy shall provide that it may not be
     canceled or altered without at least thirty (30) days prior written notice
     to Sublandlord. All such policies shall comply in all respects with the
     requirements contained in the Prime Lease relative to the insurance
     required to be maintained by Sublandlord. Subtenant shall not do or permit
     anything to be done which shall invalidate the insurance policies referred
     to in this section.

     13. Subletting and Assignment. Subtenant may not assign, convey, mortgage,
sublet or otherwise transfer or encumber all or any part of the Subleased
Premises or Subtenant's interest in this Sublease, or permit the use or
occupancy of the Subleased Premises or any part thereof by anyone other than
Subtenant and its employees, without the prior written consent of the
Sublandlord and the Primary Landlord (whose conditions for consenting to a
sublease or assignment are outlined in Article VIII of the Prime Lease).
Acceptance of rent by Sublandlord from any person other than Subtenant shall not
be deemed to be a waiver by Sublandlord of this Section, and consent to one or
more assignments or sublettings shall not be deemed consent to any subsequent
assignment or subletting. For purposes of this Sublease, any transfer or
issuance of any ownership interest (e.g., stock in a corporation, partnership
interests, limited liability company interests or beneficial interests of
trusts) in Subtenant (whether as a result of a voluntary transfer, issuance of
additional ownership interests, death, redemption, bankruptcy, UCC sale or other
involuntary transfer, or by operation of law) which transfer or issuance results
in a change in the identity of those persons beneficially owning more than fifty
percent of the outstanding ownership interests of Subtenant from that in effect
on the date of this Sublease shall constitute an assignment of this Sublease
requiring the consent of Sublandlord and Primary Landlord.

     14. Casualty or Condemnation. In the event of casualty or condemnation of
the Subleased Premises or the Leased Premises or any of their respective
component parts, the terms and conditions of the Prime Lease shall govern the
parties' respective rights and obligations under this Sublease, and in no event
shall Subtenant have any greater rights under this Sublease than Sublandlord has
under the Prime Lease. If the Prime Lease grants to Sublandlord any rights to
terminate or not terminate the Prime Lease in the event of a casualty or
condemnation or grants any rights with respect to any insurance proceeds or
condemnation awards which may become payable with respect thereto, then it is
agreed by the parties that Subtenant shall have no rights with respect thereto
other than to make a claim under any insurance policy or policies which
Subtenant may maintain.

     15. Sublandlord's Covenants, Representations and Warranties. Sublandlord
covenants and agrees with Subtenant that:

          15.1 Sublandlord has the right to enter into this Sublease, subject to
     approval of the Primary Landlord.

          15.2 Sublandlord will put Subtenant in possession of the Subleased
     Premises, and Subtenant upon paying the rent hereinabove (except for any
     credits owed to Subtenant pursuant to Section 9(c) of this Sublease) and
     observing and performing the several covenants and stipulations herein on
     its part contained, shall peaceably hold and enjoy the Subleased Premises
     during the Sublease Term without any interruption by Sublandlord.

          15.3 Sublandlord shall use all commercially reasonable efforts to
     cause Primary Landlord to furnish those utilities and other services to the
     Subleased Premises described in Article VII of the Prime Lease, during the
     hours provided therein. Subtenant shall have the same obligation to
     reimburse Sublandlord for increased expenses cause by Subtenant's use of
     the Subleased Premises after normal business hours as is imposed on
     Sublandlord under the Prime Lease with respect to such after-hours use.

          15.4 Sublandlord shall comply with its covenants and obligations set
     forth in the Prime Lease, and Sublandlord shall not agree to terminate its
     interest in the Subleased Premises without Subtenant's prior written
     consent. Subtenant's claims against Sublandlord, if any, arising out of any
     breach of the Prime Lease as a result of an act or omission of Sublandlord,
     shall survive any termination of the Prime Lease. Notwithstanding the
     foregoing, Sublandlord shall have no liability to Subtenant under this
     Sublease in the event that the Prime Lease is terminated because of
     Subtenant's breach of its obligations under this Sublease or any other act
     or omission of Subtenant which effects a termination of the Prime Lease.
     Sublandlord shall have no obligation to Subtenant to perform any obligation
     assumed by Subtenant under this Sublease in order to prevent a termination
     of the Prime Lease.

          15.5 On or before December 13, 1999, Sublandlord shall cause all safe
     deposit boxes to be emptied of their contents, and all keys thereto,
     properly marked to identify the boxes or doors they fit, shall be delivered
     to Subtenant.

     16. Subtenant's Covenants. Reoresentations and Warranties. Subtenant
covenants, represents, warrants and agrees with Sublandlord:

          16.1 Subtenant shall pay the rent in the time and the manner herein
     provided.

                                      -9-
<PAGE>

          16.2 Subtenant shall permit Sublandlord and the Primary Landlord to
     enter the Subleased Premises at any reasonable time for the purpose of
     inspecting, maintaining and cleaning the same and making necessary repairs
     to the building and the equipment and fixtures contained therein.

          16.3 Subtenant shall surrender the Subleased Premises and all
     appurtenances thereto at the end of the Sublease Term (whether at the
     stated end of such term or by early termination by forfeiture or otherwise)
     in the same condition as received, ordinary wear and tear excepted, and
     shall surrender all keys and duplicates thereof. Subtenant shall remove all
     of its personal property and removable trade fixtures (but shall not remove
     any personal property or fixtures owned by Primary Landlord or Sublandlord)
     from the Subleased Premises prior to the expiration or earlier termination
     of the Sublease Term and shall repair any damage caused by the removal
     thereof, and Subtenant shall surrender possession of the Subleased Premises
     in broom clean condition.

          16.4 Subtenant shall, at its cost, obtain all licenses, permits,
     qualifications, registrations or other authorizations required in
     connection with the operation of its business as a full-service banking
     facility at the Subleased Premises (the "Regulatory Approvals"). Subtenant
     represents and warrants that all applications required to obtain the
     Regulatory Approvals have been filed with the appropriate parties and are
     pending as of the date of this Sublease. No representation is made by
     Sublandlord that Subtenant's use of the Subleased Premises is permitted
     under applicable zoning or land use laws. Subtenant shall not use or permit
     to be used the Subleased Premises in any manner that will (a) constitute a
     hazard or an unreasonable annoyance to other tenants in the Building or any
     adjoining properties, (b) cause the Subleased Premises or the Building or
     both to suffer waste, (c) violate any laws, (d) permit any noxious odors or
     vapors to be emitted from the Subleased Premises, or (e) violate, suspend,
     void or serve to increase the premium of any policy or policies of
     insurance at any time carried on the Building or any part thereof,
     including the Subleased Premises. Subtenant shall not violate or permit the
     violation of any restrictive covenant or other condition of title affecting
     the Building. Subtenant shall not permit any hazardous substance or toxic
     waste to be handled, generated, stored, treated, disposed of or released on
     or in the Subleased Premises.

          16.5 Sublandlord shall not be liable to Subtenant for any interruption
     of services to or unavailability of materials at the Subleased Premises or
     the Building (including, without limitation, utilities, trash removal and
     maintenance) caused by circumstances not within the reasonable control of
     Sublandlord or by strikes or labor disputes.

          16.6 Sublandlord shall not be liable to Subtenant or its employees and
     agents for injury or damage to persons or property caused by the theft,
     vandalism or other criminal or tortious conduct of others (except for
     Sublandlord), and Subtenant hereby acknowledges that Subtenant's occupancy
     of the Subleased Premises and use of the common areas of the Building is at
     Subtenant's own risk.

     17. Hold Harmless: Indemnification. Sublandlord shall not be liable for any
damage occasioned by failure to keep the Subleased Premises in repair, and it
shall not be liable for any damage arising from the action or negligence of
Subtenant, co-tenants or other occupants of the Building. Subtenant shall defend
(by counsel acceptable to Sublandlord), pay, indemnify and save harmless
Sublandlord, its agents and employees, from and against any and all claims,
demands, fines, suits, actions, proceedings, orders, decrees and judgments of
any kind or nature by or in favor of anyone whomsoever and from and against any
and all costs and expenses incurred by Sublandlord, including attorneys' fees,
resulting from or in connection with any of the following, unless the same are
caused by Sublandlord's gross negligence or willful misconduct: (a) any
accident, bodily injury, death, personal

                                      -10-
<PAGE>

injury of any kind, or property damage arising directly or indirectly, out of or
from or on account of any occurrence an, upon, at or about the Subleased
Premises; (b) any accident, bodily injury, death, personal injury or property
damage arising, directly or indirectly, in connection with Subtenant's operation
and conduct of business on or in the Subleased Premises, or suffered by any of
Subtenant's employees, agents, contractors or invitees; (c) any use, occupancy,
non-use or condition of the Subleased Premises; and (d) any failure on the part
of Subtenant to perform or comply with any of the agreements, terms, covenants
and conditions of this Sublease. In case any action, suit or proceeding is
brought against Sublandlord by reason of any such occurrence, Subtenant or
Subtenant's insurer, upon Sublandlord's request, will at no expense to
Sublandlord resist and defend such action, suit or proceeding or cause the same
to be resisted and defended by counsel designated by Subtenant and approved by
Sublandlord. The obligations of Subtenant under this Section shall survive any
termination of this Sublease.

     18. Events of Default. If any one or more of the following events occurs,
then the same shall constitute an event of default on the part of Subtenant
under this Sublease:

          18.1 The failure of Subtenant to make any payment of Monthly Base
     Rent, additional rent or other sum required to be paid when due or within
     seven (7) days after Sublandlord sends notice of such failure to Subtenant.

          18.2 The failure of Subtenant to perform or observe any of the other
     terms or conditions of this Sublease (including, without limitation, the
     terms and conditions of the Prime Lease to the extent that the same are
     obligations of Subtenant hereunder) to be observed or performed by
     Subtenant; provided, however, that if such event is not otherwise set forth
     in this Section 18 and Subtenant cures such default within thirty (30) days
     after Sublandlord sends Subtenant written notice of such default, no event
     of default shall occur under this Sublease; further provided, that if such
     event is not reasonably capable of cure within such thirty (30) day period,
     no event of default shall occur if (a) Subtenant promptly commences and
     diligently pursues cure, and such event is cured not later than sixty (60)
     days after Sublandlord sends Subtenant written notice of such default; and
     (b) no default or event of default occurs under the Prime Lease;

          18.3 The failure of Subtenant to remedy, immediately after receipt of
     notice from Sublandlord, any hazardous condition which Subtenant has
     created or suffered in breach of subtenant's obligations under this
     Sublease;

          18.4 Except as expressly permitted under this Sublease, the purported
     subletting of the Subleased Premises or purported assignment of this
     Sublease by Subtenant without the prior written consent of Sublandlord and
     Primary Landlord;

          18.5 The abandonment of the Subleased Premises by Subtenant;

          18.6 Subtenant becomes insolvent or admits its inability to pay its
     creditors, or becomes the subject of a bankruptcy proceeding filed by or
     against it, or otherwise suffers any material adverse change in its
     financial condition; or

          18.7 The subleasehold interest of Subtenant is levied upon under
     execution or is attached by process of law.

          18.8 Subtenant shall breach any of its obligations set forth in
     Sections 3 (subject to any applicable cure rights), 8, 9(b), 9(c), 11, 12,
     13, 16.4, or 28 of this Sublease.

                                      -11-
<PAGE>

          18.9 Any material representation or warranty made by Subtenant
     hereunder shall prove to have been untrue when made.

     19. Remedies. If an event of default occurs on the part of Subtenant under
this Sublease, then Sublandlord may exercise any one or more of the following
remedies, to the extent permitted by law, or any other legal or equitable remedy
permitted under applicable law:

          19.1 Sublandlord may terminate this Sublease upon the delivery of
     notice thereof to Subtenant, and Sublandlord shall have the right to
     immediate possession of the Subleased Premises and Subtenant shall
     peacefully surrender possession of the Subleased Premises to Sublandlord.
     Subtenant hereby waives any and all rights it may have, at law or in
     equity, to the receipt of notice of default or demand for forfeiture,
     except as expressly provided herein. In the event Subtenant holds the
     Subleased Premises over beyond the termination of the Sublease Term,
     Sublandlord shall have the right to recover Sublandlord's cost in
     recovering possession of the Subleased Premises (including, without
     limitation, attorneys' fees and litigation costs), such amounts as may be
     permitted under applicable law and any other amounts due and payable to
     Sublandlord hereunder (including, without limitation, any past-due Rent).

          19.2 Sublandlord, without terminating this Sublease, shall have the
     right to terminate Subtenant's right to possess the Subleased Premises and
     to recover possession thereof and Subtenant shall peacefully surrender the
     Subleased Premises to Sublandlord. Subtenant hereby waives any and all
     rights it may have, at law or in equity, to the receipt of notice of
     default or demand for forfeiture, except as expressly provided herein.
     Sublandlord, at Sublandlord's option, may cause the Subleased Premises to
     be prepared for reletting, and may relet the Subleased Premises or any part
     thereof as agent of Subtenant, for a term to expire prior to, at the same
     time as, or subsequent to the expiration of the Sublease Term, at
     Sublandlord's option. In the event of such reletting, Sublandlord shall
     receive the rents therefor, applying the same first, to the repayment of
     reasonable expenses as Sublandlord may have incurred in connection with
     said resumption of possession, preparing for reletting and reletting
     (including, without limitation, remodeling costs, brokerage and attorneys'
     fees), and, second, to the payment of damages and amounts equal to the
     Monthly Base Rent and additional rent due hereunder and to the cost of
     performing the other obligations of Subtenant as herein provided.
     Subtenant, regardless of whether Sublandlord has relet the Subleased
     Premises, shall pay to Sublandlord damages equal to the Monthly Base Rent
     and additional rent herein agreed to be paid by Subtenant less the costs
     and proceeds of the reletting, if any, and such Rent shall be due and
     payable by Subtenant by on the days on which Rent is due hereunder or, in
     the alternative and at the option of Sublandlord, Subtenant shall
     immediately pay all amounts of Monthly Base Rent payable during the
     Sublease Term reduced by the rental value thereof discounted to present
     value at the rate of three percent (3%) per annum.

          19.3 Sublandlord may perform for Subtenant any of the obligations
     Subtenant has agreed to perform hereunder if Subtenant has defaulted in the
     performance of such obligations. Upon demand, Subtenant shall reimburse
     Sublandlord for Sublandlord's cost of performing for Subtenant, together
     with interest thereon at a rate equal to ten percent (10%) per annum,
     compounded monthly. Any amounts so expended by Sublandlord shall be
     immediately due and payable, and the failure of Subtenant to pay such
     amounts shall entitle Sublandlord to all of the rights and remedies
     available to it as if Subtenant had defaulted in the payment of Rent.

                                      -12-
<PAGE>

          19.4 Subtenant shall pay to Sublandlord a late charge equal to five
     percent (5%) of the amount of any installment of Monthly Base Rent or
     additional rent if such installment becomes more than ten (10) days past
     due.

          19.5 Subtenant shall pay to Sublandlord, upon demand, interest at the
     rate of twelve percent (12%) per annum on any past-due payments of Monthly
     Base Rent, additional rent or other amounts due hereunder.

     20. Headings. The headings of the paragraphs of this Sublease are inserted
only for reference and convenience and the Sublease is to be construed in all
respects as if said headings did not appear hereon.

     21. Parking. During the Sublease Term and provided that no event of default
has occurred on the part of Subtenant and is continuing under this Sublease,
Subtenant shall have a license to use forty-two (42) unreserved garage parking
spaces in the parking garage connected to the Building. No charge shall be
assessed for the license to park in the foregoing spaces. Parking shall be
subject to such rules and regulations as may be established from time to time by
Primary Landlord.

     22. Common Areas. Subtenant shall keep and maintain Subtenant's lobby area
in a clean and orderly condition free and clear of any debris. Subtenant shall
not permit storage of any material or equipment in Subtenant's lobby to be
visible from the common areas of the Building. Upon Primary Landlord's request,
Subtenant shall remove any materials, equipment, furnishings or debris from
Subtenant's lobby that is visible from the common areas of the Building that is
in not consistent with the image of a first class office property. No signs,
marquis, flags, banners, placards, streamers or other display shall be hung,
maintained or displayed on or from Subtenant's windows in the Subleased
Premises.

     23. Building Signage. After the conditions set forth in Sections 36 and 37
are satisfied, Subtenant shall have the right, at its sole cost and expense, to
have Primary Landlord erect and maintain signage inside and outside the Building
as permitted by Primary Landlord, and provided that such signage complies with
the standard graphics used on the Building signage. Subtenant has the right to
request the removal of all signs bearing Sublandlord's name (except for signage
relating to the Building's name, "Magna Place"), in which event such signs shall
be removed by Primary Landlord at Sublandlord's sole cost and expense within a
reasonable period of time after Subtenant's request, except to the extent such
signs relate to any use or occupancy of the Building by Sublandlord as of the
Commencement Date. Notwithstanding anything to the contrary in this Sublease or
the Primary Lease, in no event shall Sublandlord or the Primary Landlord be
required to reimburse Subtenant for any costs or expenses incurred by Subtenant
in connection with any change in the name or address of the Building.

     Notwithstanding anything to the contrary in this Section 23, prior to the
satisfaction of the conditions set forth in Sections 36 and 37 of this Sublease,
(a) Primary Landlord shall, within a reasonable period of time after the date of
this Sublease, at Subtenant's expense, cause Subtenant to be included on all
tenant directories for the Building (excluding the exterior monument signage),
and (b) Subtenant shall have the right, at its sole cost and expense, to have
Primary Landlord erect and maintain signage outside the Building directing
vehicular traffic to the parking facilities for the Subleased Premises, all such
signage to comply with the standard graphics used on the Building signage.

     24. No Waiver. No waiver of any default of a party hereunder shall be
implied from any omission by such party to take any action on account of such
default if such default persists or is

                                      -13-
<PAGE>

repeated, and no waiver shall affect any default other than the default
specified in the waiver and that only for the time and to the extent herein
stated.

     25. No Warranties: Amendments. Subtenant acknowledges and agrees that it
has not relied upon any statements, representations, agreements, or warranties
except as are expressed in writing herein, and that no amendment or modification
of this Sublease shall be valid or binding unless expressed in writing and
executed by the parties hereto in the same manner as the execution of this
Sublease. This Sublease may be executed in any number of counterparts, each of
which shall be deemed an original and all of which together shall constitute one
and the same instrument. The undersigned representatives of Sublandlord and
Subtenant each represent and warrant, respectively, that such persons have been
duly authorized and directed to execute and deliver this Sublease on behalf of
the party for which such person purports to be acting and that this Sublease
constitutes the legal, valid and binding obligations of such parties. This
Sublease supersedes any prior oral or written agreements relative to the subject
matter hereof and constitutes the entire agreement of the parties with respect
to the sublease of the Subleased Premises.

     26. Attorneys' Fees. The parties hereby agree that if any litigation occurs
under this Sublease, then the nonprevailing party shall reimburse the prevailing
party for the prevailing party's expenses (including, without limitation,
reasonable attorneys' fees and court costs) incurred in connection with such
litigation.

     27. Successors and Assigns. This Sublease shall be binding upon and inure
to the benefit of Sublandlord and Subtenant and their respective personal
representatives, heirs, successors, and permitted assigns. If there shall be
more than one Subtenant, they shall be bound jointly and severally by the terms,
covenants and agreements herein.

     28. Recording. No party shall have the right to record this Sublease or any
memorandum hereof without the prior written consent of the other parties hereto.
Any recording of this Sublease or any memorandum hereof without such consent
shall constitute a breach of a material provision of this Sublease entitling the
other parties to exercise any rights or remedies available hereunder or under
applicable law as a result thereof.

     29. Holding Over. Nothing contained herein is to be construed to give
Subtenant the right to hold over any time, and Sublandlord and Primary Landlord
may exercise any and all remedies at law or in equity to recover possession of
the Subleased Premises and damages resulting from any such holding over.
Subtenant agrees that if Subtenant fails to surrender possession of the
Subleased Premises at the end of the Sublease Term (or any earlier date that the
Sublease Term has been terminated), then, in addition to any other of
Sublandlord's rights and remedies, Subtenant will be liable to Sublandlord and
Primary Landlord for any and all losses, damages and expenses that Sublandlord
suffers or incurs as a result of such failure to surrender possession. Without
limiting the generality of the foregoing, Subtenant shall indemnify, defend (by
counsel acceptable to Sublandlord) and hold Sublandlord harmless from any and
all losses, damages and expenses suffered or incurred by Sublandlord resulting
from Sublandlord's inability to deliver possession of the Subleased Premises (or
any portion thereof) to any possible succeeding tenant (or to Primary Landlord
as required under the Prime Lease), which inability results from Subtenant's
failure to surrender possession of the Subleased Premises as required herein.
Such indemnification shall be in addition to any other right or remedy available
to Sublandlord under this Sublease or applicable law in the case of any holding
over of the Subleased Premises beyond the expiration or earlier termination of
the Sublease Term and shall survive any termination of this Sublease.

                                      -14-

     30. Brokerage. Subtenant represents and warrants that it has dealt solely
with Krombach Partners, Inc. ("Subtenant's Agent"), which has served solely as
the agent for Subtenant in connection with this Sublease and is not a sub-agent
of Sublandlord, and Crow Brokerage Company d/b/a Trammell Crow Company, which
has served as agent for Sublandlord, and that Subtenant has not dealt with any
other broker, agent or other person in connection with this transaction and that
no other broker, agent or other person brought about this transaction. Subtenant
agrees to indemnify and hold Sublandlord and Primary Landlord harmless from and
against any claim by any broker, agent or other person claiming a commission or
other form of compensation by virtue of having dealt with Subtenant with regard
to this leasing transaction. The provisions of this section shall survive the
termination of this Sublease. Sublandlord's Agent shall be paid an amount equal

     36. Conditions of Primary Landlord Approval: Consents. The foregoing

shall not create any relationship of landlord and tenant between Subtenant and
Primary Landlord, (ii) Sublandlord shall not be relieved of any obligations to
Primary Landlord under the Prime Lease, (iii) Primary Landlord shall not be
obligated to recognize this Sublease in the event of termination for any reason
of the Prime Lease, and (iv) Subtenant pays all legal fees incurred by Primary
Landlord in connection with the negotiation, execution and delivery of this
Sublease. Subtenant agrees to provide all information required by Article VIII
of the Prime Lease and all other information and items required by the Primary
Landlord and Sublandlord to obtain the Primary Landlord's continuing consent to
this Sublease. Notwithstanding anything to the contrary in this Sublease,
Primary Landlord's consent to this Sublease is contingent upon Subtenant's
receipt of all Regulatory Approvals and delivery of notice of receipt of the
same (together with such evidence of the same as may be required by Sublandlord
or Primary Landlord) to Sublandlord and Primary Landlord on or before July 1,
2000, and if the foregoing contingency is not satisfied, Primary Landlord's
consent to this Sublease shall be deemed automatically withdrawn on July 1, 2000
without any action required by Primary Landlord, Sublandlord or Subtenant.
Provided all applications required to obtain Subtenant's Regulatory Approvals
are pending, Subtenant is diligently pursuing the Regulatory Approvals, the
failure to obtain the Regulatory Approvals on or before July 1, 2000 is not due
to any condition or circumstance caused by Subtenant or its agents, and no event
of default has occurred under this Sublease, Primary Landlord will not
unreasonably withhold its consent to extend the July 1, 2000 deadline to August
1, 2000, or for additional thirty (30) day periods until Subtenant obtains the
Regulatory Approvals. If Subtenant desires to request an extension of Primary
Landlord's consent to this Sublease, it shall deliver a written request for
extension to Primary Landlord and Sublandlord at least five (5) business days
prior to the date on which Primary Landlord's consent will be deemed withdrawn,
together with such evidence of the foregoing conditions to extension as Primary
Landlord may require.

     37. Termination if Regulatory Approvals Not Obtained. Notwithstanding
anything to the contrary in this Sublease, this Sublease shall automatically
terminate without any action required by

                                      -16-
<PAGE>

Sublandlord or Subtenant if Subtenant does not receive its Regulatory Approvals
and deliver notice of receipt of the same (together with such evidence of the
same as may be required by Sublandlord or Primary Landlord) to Sublandlord and
Primary Landlord on or before July 1,2000; provided, however, if Primary
Landlord has agreed to extend its consent to this Sublease beyond July 1,2000,
and no event of default has occurred under this Sublease, this Sublease shall
not terminate until such date, if any, on which Primary Landlord's consent is
deemed automatically withdrawn.

     38. Counterparts. This Sublease may be executed in any number of
counterparts (including telecopy counterparts), each of which shall be deemed an
original and together shall constitute one and the same instrument. Counterparts
of this Sublease which have been executed and sent by facsimile to the other
parties shall have the same effect as the hand delivery of executed originals.
