This Indenture, dated May 22, 2001.

         WITNESSETH: That Research Boulevard Partnership, (the Landlord), hereby
leases unto R. E. Stafford, Inc, d.b.a. Colo Solutions having its principal
place of business at P0 Box 411570, Melbourne, Florida 32941-1570__ (the Tenant)
and the Tenant accepts from Landlord the leased premises (125 N. MARKET, Suite
210, WICHITA KANSAS 67202) containing approximately 1,224 rentable square feet
as defined by BOMA standards outlined on the floorplan(s) attached hereto as
Exhibit A, (the Premises), in the building known as The KSB Building located at
123-125 North Market, Wichita Kansas, 67201 (the Building) (said Building,
together with the land on which it is located and all other improvements thereon
being called the Property), for the term, the rent, and subject to the
conditions and covenants hereinafter provided.

         The term of this lease shall commence on June 8, 2001, and shall end on
June 7, 2005 or 48 months from the date possession is tendered to Tenant, unless
sooner terminated as provided herein, to be occupied and used by the Tenant for
general offices and for no other purposes whatsoever. No easement for light or

In consideration thereof, the parties covenant and agree as follows:

1.  RENT

         (a) Tenant shall pay to the Landlord as Base Rent, in legal tender at
the Landlord's Agent's office of KEY MANAGEMENT COMPANY, 125 N. MARKET, SUITE
1510, WICHITA, KANSAS 67202, or as directed from time to time by Landlord's
notice the annual sum of SEVENTEEN THOUSAND ONE HUNDRED THIRTY SIX DOLLARS AND
NO/100 ($17,136.00), payable in equal monthly payments of ONE THOUSAND FOUR
HUNDRED TWENTY EIGHT DOLLARS AND NO/100 ($1,428.00) in advance promptly on the
first day of every calendar month of the term, except for the first month's rent
which is due and payable on execution, and prorata, in advance, for any partial
month, without demand, the same being hereby waived and without any set-off or
deduction whatsoever. Interest at the per annum rate of 10% will be charged
retroactive to the first day of the month for rents not paid by the tenth (10th)
of the calendar month. No payment by Tenant or receipt by Landlord of a lesser
amount than the monthly installments of Rent (herein defined) herein stipulated
shall be deemed to be other than on account of the earliest stipulated Rent nor
shall any endorsement or statement on any check or any letter accompanying any
check or payment as Rent be deemed an accord and satisfaction, and Landlord may
accept such check for payment without prejudice to Landlord's right to recover
the balance of such Rent or to pursue any other rent provided in this lease.

         (b) The annual Base Rent payable pursuant to Paragraph (a) shall be
increased by Taxes and Operating Expenses in excess of the Fixed Amount as
defined in Paragraph 1(c). The Base Rent, as so increased, together with any and
all other charges due Landlord from Tenant pursuant to the terms of this Lease,
is hereinafter called the "Rent". Certain terms are defined as follows:

         Tenant's Share: The amount of Tenant's prorata share of the increase in
Taxes and Operating Expenses in excess of the fixed amount during each calendar
year. Tenant's prorata share of such increase is agreed to be .39% (rentable
area leased/total building rentable area).

         Taxes: (i) All real estate taxes, including State equalization factor
if any, payable (adjusted after protest or litigation, if any) for any part of
the term of this Lease, exclusive of penalties or discounts, on the Property,
(ii) any taxes which shall be levied in lieu of any such taxes on the gross
rentals of the Property, (iii) any special assessments against the Property
which shall be required to be paid during the calendar year in respect to which
taxes are being determined (including Benefit District Assessments) and (iv) the
expense (including attorney fees) of contesting the amount or validity of any
such taxes, charges or assessments, such expense to be applicable to the period
of the item contested. Landlord shall have no obligation to contest, object or
litigate the levying or imposition of any Taxes and may settle, compromise,
consent to, waive or otherwise determine in its discretion any Taxes without
consent or approval of Tenant.

<PAGE>

         Operating Expenses: Those expenses incurred or paid on behalf of the
Landlord in respect to the operation, maintenance, repair and management of the
Property which, include, but are not limited to property insurance premiums,
replacement and or repair of HVAC equipment, electrical repairs and supplies,
plumbing repairs and supplies, building equipment maintenance and repairs,
landscaping maintenance, maintenance and repairs to walks and parking areas
(including sealcoating and asphalt overlay), electricity, gas, sewer, water, and
any other utilities furnished to the Premises and the common areas, five (5)
days per week janitorial service for the Premises and common areas, janitorial
supplies, management services, roof repairs, elevator maintenance, interior
common area and exterior painting, trash removal, maintenance and replacement of
floor coverings in common areas, pest control, lamp replacement in the common
areas and the Premises, window washing, and any other property maintenance and
operation expenses which may be required from time to time in maintaining the
Property in a prudent manner, and the cost, as reasonably amortized by the
Landlord, with interest at the rate of 10% per annum on the unamortized amount,
of any capital improvement made after completion of initial construction of the
Building which reduces other Operating Expenses, but in an amount not to exceed
such reduction for the relevant year. If Landlord makes any capital improvement
during the term of this lease in order to comply with safety or any other
requirements of any federal, state or local law or government regulation, then
the Tenant's Share of the reasonable annual amortization of the cost of such
improvement, with interest at the highest rate permitted by applicable law,
shall be deemed an Operating Expense in each of the calendar years during which
such amortization occurs, and the Tenant shall be responsible for Tenant's Share
of any such charges. Operating Expenses shall not include franchise or income
taxes imposed on the Landlord, except to the extent hereinbefore provided, nor
the cost to the Landlord of any work or service performed in any instance for
any tenant (including the Tenant) at the cost of such tenant.

         (c) In order to provide for current payments on account of increases in
the Taxes and Operating Expenses in excess of 2001 base year Taxes and Operating
Expenses (said sum being defined as the "Fixed Amount") the Tenant agrees at
Landlord's request, to pay, as additional rent, Tenant's Share due for each
calendar year after the base year, as estimated by Landlord from time to time,
in twelve (12) monthly installments, during the calendar year, each in an amount
equal to 1/12th of Tenant's Share so estimated by Landlord. The monthly
estimated payments shall commence and any adjustment amount for the estimated
payments in the current calendar year shall be due or credited, if applicable,
on the first day of the month following the month in which Landlord notifies
Tenant of the amount of such estimated Tenant's Share. If, as finally
determined, Tenant's Share shall be greater than or be less than the aggregate
of all installments so paid on account to the Landlord for such calendar year,
then Tenant shall pay to Landlord the amount of such underpayment, or the
Landlord shall credit Tenant for the amount of such overpayment to Tenant's
future payments of Taxes and Operating Expenses, as the case may be. It is the
intention hereunder to estimate the amount of Taxes and Operating Expenses for
each calendar year and then to adjust such estimate in the following year based
on actual Taxes and Operating Expenses incurred and/or paid by Landlord. The
obligation of the Tenant with respect to the payment of Rent shall survive the
termination of this Lease. Any payment, refund, or credit made pursuant to this
paragraph (c) shall be made without prejudice to any right of the Tenant to
dispute, or of the Landlord to correct, any item(s) as billed pursuant to the
provisions hereof.

         (d) Upon receipt of the Landlord's statement, Tenant does hereby
covenant and agree promptly to pay the increases in Rent pursuant to Paragraph
(c) of this Section as and when the same shall become due and payable, without
further demand therefor, and without any set-off or deduction whatsoever.
Failure to give such statement shall not constitute a waiver by Landlord of its
right to require an increase in Rent nor shall such failure deprive Tenant of a
decrease in Rent, as the case may be.

         (e) Within thirty (30) days after receipt of such statement, Tenant or
its authorized employee shall have the right to inspect the books of Landlord
during the business hours of Landlord at Landlord's office in the Building or,
at Landlord's option, at such other location that Landlord may specific, for the
purpose of verifying information in such statement. Unless Tenant asserts
specific error(s) within thirty (30) days after delivery of such statement, the
statement shall be deemed to be correct.

         (f) No decrease in Taxes and/or Operating Expenses shall reduce
Tenant's Rent below the annual Base Rent set forth in Paragraph (a) of this
Section.


<PAGE>

         (g) All costs and expenses which Tenant assumes or agrees to pay to
Landlord pursuant to this lease shall be deemed additional rent and, in the
event of non-payment thereof, Landlord shall have all the rights and remedies
herein provided for in case of non-payment of Rent.

2.  SERVICES

         The Landlord shall provide, at Landlord's expense, except as otherwise
provided, the following services:

         (a) Air conditioning and heat for normal general office purposes only,
to provide in Landlord's judgment comfortable occupancy Monday through Friday
from 7:00 a.m. to 7:00 p.m., and Saturday from 8:00 a.m. to 1:00 p.m., Sundays
and holidays excepted. Tenant agrees not to use any apparatus or device, in or
upon or about the Premises which in any way may increase the amount of such
services usually furnished or supplied to said Premises, and Tenant further
agrees not to connect any apparatus or device with the conduits or pipes, or
other means by which such services are supplied, for the purpose of using
additional or unusual amounts of such services, without written consent of
Landlord. Should Tenant use such services under this provision to excess or
requests the use of these services at other than operating hours listed above,
Landlord reserves the right to charge for such services. The charge shall be
payable as additional rent. Should Tenant refuse to make payment upon demand of
Landlord of such charges, such refusal shall constitute a breach of the
obligation to pay rent under this lease and shall entitle Landlord to the rights
hereinafter granted for such breach. Tenant will install a separate electric
sub-meter for the demised space which shall cover all consumption of electricity
on the demised premises. Tenant will pay for electricity usage based on the
monthly sub-meter readings at the then current rates as invoiced. Tenant is
hereby authorized to augment existing electrical, air conditioning and fire
suppression systems as set forth in paragraph 11.(o). All future changes must be
presented to Landlord in writing prior to any changes made.

         (b) Electric power for lighting and operation of office machines, air
conditioning and heating as may be required for comfortable occupancy of the
Premises between Monday and Friday from 7:00 am. to 7:00 p.m. and Saturdays from
8:00 a.m. to 1:00 p.m., Sundays and holidays excepted. Electric power furnished
by the Landlord is intended to be that consumed in normal office use for
lighting, heating, ventilating, air conditioning and small office machines.
Landlord shall read the tenants sub-meter monthly, and invoice the tenant for
the electricity used at the then prevailing electric utility rates. If the
Tenant refuses to pay upon demand of Landlord such charges, such refusal shall
constitute a breach of the obligation to pay Rent under this lease and shall
entitle Landlord to the rights hereinafter granted for each breach.

         (c) Water for drinking, lavatory and toilet purposes from the regular
Building supply (at the prevailing temperature) through fixtures installed by
Landlord, (or by Tenant with Landlord's written consent).

         (d) Public restroom supplies, public area lamp replacement, window
washing with reasonable frequency, and janitor services to the Premises during
the times and in the manner that such janitor services are customarily furnished
(not more than 5 times per week) in general office buildings in the area.

         (e) A total of 0 parking stalls will be provided subject to
availability, in the parking garage adjacent to the Building on an assigned
basis at market price.

         (f) Landlord agrees to maintain the exterior and interior of the
Premises to include lawn and shrub care, if applicable, snow removal,
maintenance of the structure, roof, mechanical and electrical equipment,
interior finishes, and so on, excluding only those items specifically excepted
elsewhere in this lease and special interior improvements unique to Tenants
Premises.

         (g) Landlord may close the Building at 7:00 p.m. Monday through Friday,
1:00 p.m. on Saturday and all day Sunday and holidays, or at such other hours as
Landlord may from time to time reasonably determine; after which hour admittance
may be gained only under such regulations as may from time to time be prescribed
by Landlord. Notwithstanding the above, tenant and its customers shall have
access to their space 24x7x365.


<PAGE>

         (h) All building standard lamp replacement within the Tenant's demised
areas shall be replaced by the Landlord.

         Should Tenant require any additional work or service, including but not
limited to the work or service described above, including service furnished
outside the stipulated hours, Landlord may, on terms to be agreed, upon
reasonable advance notice by Tenant, furnish such additional service and Tenant
agrees to pay the Landlord such charges as may be agreed on, but in no event at
a charge less than Landlord's actual cost plus overhead for the work or services
provided, it being agreed that the cost to the Landlord of such additional
services shall be excluded from Operating Expense.

         It is understood that Landlord does not warrant that any of the
services referred to above, or any other services which Landlord may supply,
will be free from interruption. Tenant acknowledges that any one or more such
services may be suspended by reason of accident or of repairs, alterations or
improvements to be made, or by strikes or lockouts, or by reason of operation of
law, or causes beyond the reasonable control of Landlord. Any such interruption
or discontinuance of service shall never be deemed an eviction or disturbance of
Tenant's use and possession of the Premises, or any part thereof, or render
Landlord liable to Tenant for damages by abatement of rent or otherwise, or
relieve Tenant from performance of Tenant's obligations under this lease.

3. QUIET ENJOYMENT

         So long as the Tenant shall observe and perform the covenants and
agreements binding on it hereunder, the Tenant shall at all times during the
term herein granted peacefully and quietly have and enjoy possession of the
Premises without any encumbrances or hindrance by, from or through the Landlord.

         (g) At any time in the event of an emergency, and otherwise at
reasonable times, to take any and all measures, including inspections, repairs,
alterations, additions and improvements to the Premises or to the Building, as
may be necessary or desirable for the safety, protection or preservation of the
Premises or the Building or the Landlord's interests, or as may be necessary or
desirable in the operation or improvement of the Building or in order to comply
with all laws, orders and requirements of governmental or other authority.

represented by the party requesting the certificate. If Tenant fails to deliver
the certificate within ten (10) days after requested by Landlord, then by such

6. WAIVER OF CERTAIN CLAIMS

         The Tenant, to the extent permitted by law, waives all claims it may
have against the Landlord, and against the Landlord's agents and employees for
any and all damages sustained by the Tenant or by any occupant of the Premises,
or by any other person, resulting from any part of the Property or any equipment
or appurtenances becoming out of repair, or resulting from any accident in or
about the Property or resulting directly or indirectly from any act or neglect
of any tenant or occupant of any part of the Property or of any other person,
unless such damage is a result of the gross negligence or willful misconduct of
Landlord, or Landlord's agents or employees. If any damage results from any act
or neglect of the Tenant, the Landlord may, at the Landlord's option, repair
such damage and the Tenant shall thereupon pay to the Landlord the total cost of
such repair. All personal property belonging to the Tenant or any occupant of
the Premises that is in or on any part of the Property shall be there at the
risk of the Tenant or of such other person only, and the Landlord, its agents,
and employees shall not be liable for any damage thereto or for the theft or
misappropriation thereof. The Tenant agrees to defend, hold the Landlord
harmless and indemnified against any and all claims, liability, losses, damages,
causes of action, expenses, costs suffered or claimed by any person occurring in
or about the Property, due to any conduct, act of negligence or default under
this lease by the Tenant, its contractors, agents or employees.

         To the extent that the Tenant carries hazard insurance on any of its
property in the Premises and to the extent that the Landlord carries hazard
insurance on the Property, each policy of insurance shall contain, if obtainable
from the insurer selected by the Tenant or the Landlord, as the case may be,
without additional expense, a provision waiving subrogation against the other
party to this lease. Each of the parties hereto hereby releases the other with
respect to any liability which the other may have for any damage by fire or
other casualty with respect to which the party against whom such release is
claimed shall be insured under a policy of policies of insurance containing such
provision waiving subrogation.

7. INSURANCE

         Tenant shall, at its expense, obtain and maintain during the term and
any extended term of this Lease, comprehensive general liability insurance,
contractual liability insurance and property damage insurance under policies
issued by insurers of recognized responsibility, with limits of not less that
$1,000,000 for personal injury, bodily injury, death, or for damage or injury to
or destruction of property (including the loss of use thereof) for any one
occurrence. Tenant's

<PAGE>

policies shall name Landlord, its agents, servants and employees as additional
insureds. At the option of the Landlord, the originals of all policies of
insurance shall be held by Landlord. Landlord shall be notified by Tenant or
Tenant's insurance carrier at least thirty (30) days in advance of cancellation
of liability coverage.

8.  HOLDING OVER

         If the Tenant retains possession of the Premises or any part thereof
after the termination of the term, the Tenant shall pay the Landlord Rent at
double the monthly rate specified in Section I for the time the Tenant thus
remains in possession and, in addition thereto, shall pay the Landlord for all
damages, consequential as well as direct, sustained by reason of the Tenant's
retention of possession. The provisions of this Section do not exclude the
Landlord's rights of re-entry or any other right hereunder.

9. ASSIGNMENT AND SUBLETTING

         It is understood that the nature of the Tenant's business is colocation
services. The Tenant is allowed to locate their customers within the demised
space.

         Tenant shall not, without Landlord's prior written consent, which
consent may be withheld in the sole and absolute discretion of Landlord, (a)
convey, mortgage, pledge, or encumber (whether voluntarily or otherwise) this
lease or any interest under it; (b) allow any transfer or lien upon the Tenant's
interest by operation of law; (c) or sublet the Premises or any part thereof.

         Tenant agrees to pay to Landlord, on demand, reasonable costs incurred
by Landlord in connection with any request by Tenant for Landlord to consent to
any assignment or subletting by Tenant.

         If this lease be assigned or if the Premises or any part thereof be
sublet or occupied by anybody other than Tenant, Landlord may, after default by
Tenant, collect rent from the assignee, subtenant or occupant, and apply the net
amount collected to the Rent herein reserved, but no such assignment,
subletting, occupancy or collection shall be deemed a waiver of any Tenant's
covenants contained in this lease or the acceptance of the assignee, subtenant
or occupant as Tenant, or a release of Tenant from further performance by Tenant
of covenants on the part of Tenant herein contained.

         Notwithstanding anything contained herein to the contrary, in the event
that at any time during the term of this lease Tenant desires to sublet all or
part of the Premises, Tenant shall notify the Landlord in writing (hereinafter
referred to as "Sublet Notice") of the terms of the proposed subletting and the
area so proposed to be sublet and shall give the Landlord the option to sublet
from Tenant such space (hereinafter referred to as "sublet space") at the same
rent and additional rent as Tenant is required to pay to Landlord under this
lease for the same space or, at Landlord's option, to terminate the lease with
respect to the sublet space. If the sublet space does not constitute the entire
Premises and Landlord exercises its option to terminate this lease with respect
to the sublet space, then as to that portion of the Premises which is not part
of the sublet space, this lease shall remain in full force and effect except
that the Rent shall be reduced by a fraction, the numerator of which shall be
the usable square feet of the sublet space and the denominator of which shall be
the usable square feet of the Premises. The option to sublet, or to terminate
the lease, shall be exercisable by Landlord in writing for a period of
forty-five (45) days after receipt of the Sublet Notice.

         In the event Landlord exercises its option to sublease the sublet
space, the term of the subletting from the Tenant to the Landlord for the sublet
space shall be the term set forth in the Sublet Notice and shall be on such
other terms and conditions as are contained in this lease to the extent
applicable.

         In the event Landlord does not exercise either of its options specified
above and Tenant completes a sublease with a third party, the subtenant shall be
subject to and comply with the requirements of this Section.

         Tenant agrees to reimburse Landlord for Landlord's reasonable
attorneys' and administrative fees incurred in conjunction with the processing
of any documentation for each

<PAGE>

proposed transfer, whether or not the transfer is consummated, which in any
event shall not be less than Five Hundred Dollars ($500.00) per transfer.
Landlord's consent or approval to any transfer shall not be construed as a
waiver of the requirement that Landlord's consent or approval be obtained to all
subsequent transfers.

         Notwithstanding anything contained herein to the contrary, Tenant may
assign this lease in the event that they are acquired by, or merge with another
company, so long as the acquiring entity is at least as financially viable as
the tenant. Tenant shall notify Landlord in advance of an assignment and execute
such assignment documents as may be necessary.

10. CONDITION OF PREMISES

         Tenant's taking possession of the Premises shall be conclusive evidence
as against the Tenant that the Premises were in good order and satisfactory
condition when the Tenant took possession, except as to latent defects. No
promise of the Landlord to alter, remodel, repair or improve the Premises or the
Building and no representation respecting the condition of the Premises or the
Building have been made by Landlord to Tenant, other than as may be contained
herein or in a separate Work Letter Agreement signed by Landlord and Tenant. At
the termination of this lease, the Tenant shall return the Premises broom-clean
and in as good condition as when the Tenant took possession, ordinary wear and
loss by fire or other casualty excepted, failing which the Landlord may restore
the Premises to such condition and the Tenant shall pay the cost thereof on
demand.

11. USE OF PREMISES

increase the premium cost of any policy of insurance carried on the Building or
covering its operation, or which will suffer or permit the Premises or any part
thereof to be used in any manner or anything to be brought into or kept therein

improvements or additions, Tenant shall first submit to Landlord plans and
specifications therefor and obtain Landlord's written approval thereof prior to
commencing any such work.

         (g) All persons entering or leaving the Building after hours on Monday

Landlord or Tenant, applicable to Tenant and Tenant's use of the Building and
Premises. The Tenant shall not use the Premises for any illegal or immoral
purpose.

         (j) The Tenant shall cooperate fully with the Landlord to assure the
effective operation of the Building's air conditioning system, including the
closing of venetian blinds and drapes, and if windows are operable to keep them
closed when the air conditioning system is in use.

         (k) The Tenant shall not contract for any work or service which might
involve the employment of labor incompatible with the Building employees or
employees of contractors doing work or performing services by or on behalf of
the Landlord.

         (l) The sidewalks, halls, passages, exits, entrances, elevators and
stairways shall not be obstructed by the Tenant or used for any purpose other
than for ingress to and egress from its Premises. Landlord shall retain the
right to control and prevent access thereto by all persons whose presence, in
the judgment of the Landlord, shall be prejudicial to the safety, character,
reputation and interests of the Building and its tenants, provided that nothing
herein contained shall be construed to prevent such access to the persons with
whom the Tenant normally deals in the ordinary course of Tenant's business
unless such persons are engaged in illegal activities. No tenant and no
employees or invitees of any tenant shall go upon the roof or in the mechanical
rooms of the Building without the Landlords permission.

shall any animals or birds be brought in or kept in or about the Premises or the
Building.

         (n) Tenant shall see that the doors, and windows, if operable, of the

observe strict care and caution that all water faucets or water apparatus are
entirely shut off before Tenant or Tenant's employees leave the Building, and
that all electricity shall likewise be carefully shut off so as to prevent waste
or damage, and for any default or carelessness Tenant shall make good all
injuries or losses sustained by other tenants or occupants of the Building or
Landlord.

location, DC power plant equipment/system and batteries along with racks,
cabinets, cages, and cabling, all as necessary for the operation of their
business. All work shall be done at Tenants expense and performed by only
licensed contractors under such permits required for the work. All work proposed
by Tenant shall first be determined to not reduce the capacity of the base
building electrical and fire suppression systems to an extent that would prevent
the Landlord from providing service to any portion of the building. Any
modification or upgrade necessary to the base building systems as a result of
Tenant's proposed work shall be a Tenant's sole cost. In all cases, Tenant shall
retain all ownership rights to the above equipment/systems. Tenant shall, at its
option, either leave all equipment in place at the end of the lease or remove it
and restore the premises at Tenant's expense.

         In addition to all other liabilities for breach of any covenant of this
Section, the Tenant shall pay to the Landlord an amount equal to any increase in
insurance premiums payable by the Landlord or any other tenant in the Building,
caused by such breach.

or defective condition in any part or appurtenance of the Building's plumbing,

passing through the Premises. Subject to the provisions of Section 13, the
Tenant shall, at the Tenant's own expense, keep the Premises in good order,
condition and repair during the term of this lease, except that the Landlord, at
the Landlord's expense (unless damage thereto is caused by the fault or
negligence of the Tenant, its contractors, agents, employees in which case, the
same shall be maintained or repaired by Tenant, at Tenant's expense and if
Tenant fails to make such repairs promptly, Landlord, at its option, may make
such repairs and Tenant shall pay Landlord on demand Landlord's actual costs of
making such repairs plus a fee of ten percent (10%) to cover Landlord's
overhead) shall keep in repair the elevators, heating and air conditioning
equipment, outside walls, including windows, roof, electrical lines, standard
building lighting and light bulbs, switches, receptacles, plumbing fixtures,
blinds, door hardware and ceilings located in or for the Building and Premises;
provided, however that Tenant shall be responsible for the maintenance and
repair of all improvements and equipment installed by Tenant including those
items set forth m paragraph 11.(o). Landlord's cost of maintenance and repair is
subject to the provisions of Section 1. The Tenant at the Tenant's expense,
shall comply with all laws and ordinances, and all rules and regulations of all
governmental authorities and of all insurance bodies at any time in force,
applicable to the Premises or to the Tenant's use thereof, except that the
Tenant shall not hereby be under any obligation to comply with any law,
ordinance, rule or regulation requiring any structural alteration of or in
connection with the Premises, unless such alteration is required by reason of a
condition which has been created by, or at the instance of, the Tenant, or is
required by reason or a breach of any of the Tenant's covenants and agreements
hereunder. Landlord shall not be liable to Tenant for any damage or
inconvenience and Tenant shall not be entitled to any abatement or reduction of
Rent by reason of any repairs, alterations or additions made by Landlord.

13. UNTENANTABILITY

         If the Premises are made untenantable in whole or in part by fire or
other casualty the Rent, until repairs shall be made or the lease terminated as
hereinafter provided, shall be apportioned on a per diem basis according to the
part of the Premises which is usable by the Tenant, if, but only if, such fire
or other casualty be not caused by the fault or negligence of the Tenant, its
contractors, agents, or employees. If such damage shall be so extensive that the
Premises cannot be restored to the same or better quality condition than the
condition prior to the fire or other casualty by the Landlord within a period of
three (3) months, either party shall have the right to cancel this lease by
notice to the other given at any time within thirty (30) days after the date of
such damage; except that if such fire or casualty resulted from the Tenant's
fault or negligence the Tenant shall have no right to cancel. If a portion of
the Building other than the Premises shall be so damaged that in the opinion of
the Landlord the Building should be restored in such a way as to alter the
Building or Premises materially, the Landlord may cancel this lease by notice to
the Tenant given at any time within thirty (30) days after the date of such
damage. In

<PAGE>

the event of giving effective notice pursuant to this Section, this Lease and
the term and the estate hereby granted shall expire on the date fifteen (15)
days after the giving of such notice as fully and completely as if such date
were the date hereinbefore set for the expiration of the term of this lease. If
this lease is not terminated, the Landlord will promptly repair the damage at
the Landlord's expense. Landlord shall not be obligated to repair, restore or
replace any fixture improvement, alteration, furniture, personal property,
decorations or other property owned installed or made by Tenant, all of which
shall be repaired restored or replaced by Tenant.

14. EMINENT DOMAIN

         (a) In the event that title to the whole or any part of the Premises
shall be lawfully condemned or taken in any manner for any public or
quasi-public use or purpose, this lease and the term and estate hereby granted
shall forthwith cease and terminate as of the date of vesting of title and the
Landlord shall be entitled to receive the entire award, the Tenant hereby
assigning to the Landlord the Tenant's interest therein, if any.

         (b) In the event that title to a part of the Building other than the
Premises shall be so condemned or taken and if in the opinion of the Landlord,
the Building should be restored in such a way as to alter the Building or the
Premises materially, the Landlord may terminate this lease and the term and
estate hereby granted by notifying the Tenant of such termination within sixty
(60) days following the date of vesting of title, and this lease and the term
and estate hereby granted shall expire on the date specified in the notice of
termination, not less than sixty (60) days after the giving of such notice, as
fully and completely as if such date hereinbefore set for the expiration of the
term of this lease, and the Rent hereunder shall be apportioned as of such date.
Landlord shall be entitled to receive the entire award.

15. LANDLORD'S REMEDIES

         All rights and remedies of the Landlord herein enumerated shall be
cumulative, and none shall exclude any other right or remedy allowed by law. In
addition to the other remedies in this lease provided, the Landlord shall be
entitled to the restraint by injunction of the violation or attempted violation
of any of the covenants, agreements or conditions of this lease.

         (a) If the Tenant shall (i) apply for or consent to the appointment of
a receiver, trustee or liquidator of the Tenant or of all or a substantial part
of its assets, (ii) file a voluntary petition in bankruptcy or admit in writing
its inability to pay its debts as they come due, (iii) make a general assignment
for the benefit of creditors, (iv) file a petition or an answer seeking
reorganization or arrangement with creditors or to take advantage of any
insolvency law, or (v) file an answer admitting the material allegations of a
petition filed against the Tenant in any bankruptcy, reorganization or
insolvency proceeding, or if an order, judgment or decree shall be entered by
any court of competent jurisdiction adjudicating the Tenant a bankrupt or
insolvent or approving a petition seeking reorganization of the Tenant or
appointing a receiver, trustee or liquidator of the Tenant or of all or a
substantial part of its assets, then, in any such events, the Landlord may give
to the Tenant a notice of intention to end the term of this lease specifying a
day not earlier than ten (10) days thereafter, and upon the giving of such
notice the term of this lease and all right, title and interest of the Tenant
hereunder shall expire as fully and completely on the day so specified as if
that day were the date herein specifically fixed for the expiration of the term.

         (b) If the Tenant defaults in the payment of Rent or Additional Rent
and such default continues for ten (10) days after written notice or defaults in
the prompt and full performance of any other provision of this lease and such
default continues for ten (10) days after written notice, or if the leasehold
interest of the Tenant be levied upon under execution or be attached by process
of law, or if the Tenant abandons the Premises, then and in any such event the
Landlord may, at its election, either terminate the lease or retake possession
of the Premises, without terminating this lease, and endeavor to relet the
Premises. Nothing herein shall be construed so as to relieve the Tenant of any
obligation, including the payment of Rent and Additional Rent as provided in
this lease. Landlord recognizes Tenant will only occupy space with equipment.
This is not considered abandonment.

         (c) Upon any termination of this lease, the Tenant shall surrender
possession and vacate the Premises immediately, and deliver possession thereof
to the Landlord. Should the Tenant refuse to peaceably surrender and vacate the
premises, an action of forcible entry and detainer will

<PAGE>

be sought in order to provide possession to the Landlord without relinquishing
the Landlord's right to Rent, Additional Rent, or any other right given to the
Landlord hereunder or by operation of law.

         (d) If the Tenant abandons the Premises or the Landlord otherwise
becomes entitled so to elect, and the Landlord elects, without terminating the
lease, to endeavor to relet the Premises, the Landlord may, at the Landlord's
option enter into the Premises, remove the Tenant's signs and other evidence of
tenancy, and take and hold possession thereof as in Paragraph (c) of this
Section provided, without such entry and possession terminating the lease or
releasing the Tenant, in whole or in part, from the Tenant's obligation to pay
Rent and Additional Rent hereunder for the full term as hereinafter provided.
Upon and after entry into possession without termination of the lease, the
Landlord may relet the Premises or any part thereof for the account of the
Tenant to any person, firm or corporation other than the Tenant for such rent,
for such time and upon such terms as the Landlord shall determine, to be
reasonable. In any such case, the Landlord may make repairs, alterations and
additions in or to the Premises, and redecorate the same to the extent deemed by
the Landlord necessary or desirable, and the Tenant shall, upon demand, pay the
cost thereof, together with the Landlord's expenses of the reletting. If the
consideration collected by the Landlord upon any such reletting for the Tenant's
account is not sufficient to pay monthly the full amount of the Rent reserved in
this lease, together with the cost of repairs, alterations, additions,
redecorating and the Landlord's expenses, the Tenant shall pay to the Landlord
the amount of each monthly deficiency upon demand.

         (e) If the Landlord elects to terminate this lease in any of the
contingencies specified in this Section, it being understood that the Landlord
may elect to terminate this lease after and notwithstanding its election to
terminate the Tenant's right to possession as in Paragraph (d) of this Section
provided, the Landlord shall forthwith upon such termination be entitled to
recover as damages, and not as penalty, an amount equal to the then present
value of the Rent and Additional Rent provided in this lease for the residue of
the stated term hereof, less the present value of the fair rental value of the
Premises for the residue of the stated term.

         (f) In the event Tenant defaults and Landlord has been granted
possession of space, any and all property which may be removed from the Premises
by the Landlord pursuant to the authority of the lease or of law, to which the
Tenant is or may be entitled, may be handled, removed or stored by the Landlord
at the risk, cost and expense of the Tenant, and the Landlord shall in no event
be responsible for the value preservation or safe keeping thereof. The Tenant
shall pay to the Landlord, upon demand, any and all expenses incurred in such
removal and all storage charges against such property so long as the same shall
be in the Landlord's possession or under the Landlord's control. Any such
property of the Tenant not removed from the Premises or retaken from storage by
the Tenant within thirty (30) days after the end of the term or of the Tenant's
right to possession of the Premises, however terminated, shall be conclusively
deemed to have been forever abandoned by the Tenant and either may be retained
by Landlord as its property or may be disposed of in such manner as Landlord may
see fit.

         (g) The Tenant agrees that if it shall at any time fail to make any
payment or perform any other act on its part to be made or performed under this
lease, the Landlord may, but shall not be obligated to, and after reasonable
notice or demand and without waiving, or releasing the Tenant from, any
obligation under this lease, make such payment or perform such other act to the
extent the Landlord may deem desirable, and in connection therewith to pay
expenses and employ counsel. All sums so paid by the Landlord and all expenses
in connection therewith, together with interest thereon at the rate of l8% per
annum from the date of payment, shall be deemed Additional Rent hereunder and
payable at the time of any installment of Rent thereafter becoming due and the
Landlord shall have the same rights and remedies for the nonpayment thereof, or
of any other Additional Rent, as in the case of default in the payment of Rent.

16. SUBORDINATION AND ATTORNMENT

         The rights of the Tenant under this lease shall be and are subject and
subordinate at all times to all ground leases and/or underlying leases, if any,
now or hereafter in force against the Property, and to the lien of any mortgage
or mortgages now or hereafter in force against such leases and/or the Property,
and to all advances made or hereafter to be made upon the security thereof, and
to all renewals, modifications, consolidations, replacements and extensions
thereof. This Section is self-operative and no further instrument of
subordination shall be required. In

<PAGE>

confirmation of such subordination Tenant shall promptly execute such further
instruments as may be requested by the Landlord. The Tenant hereby irrevocably
appoints the Landlord as attorney-in-fact for the Tenant with full power and
authority to execute and deliver in the name of the Tenant any such instrument
or instruments.

         Upon request of any person succeeding to the interest of Landlord as a
result of the enforcement of any remedy provided for by law or pursuant to the
terms of any mortgage or assignment of rents and leases given by Landlord as
security to Landlord's mortgagee, Tenant shall automatically become the Tenant
of such successor-in-interest, without change in the terms or other provisions
of this Lease, however, such successor-in-interest shall not be (i) bound by any
payment of rent for more than one (1) month in advance, except prepayments in
the nature of security for the performance by Tenant of its obligations
hereunder, (ii) bound by any amendment or modification hereof made without the
written consent of Landlord's mortgagee or Landlord's successor-in-interest,
(iii) liable for any act or omission of any previous Landlord (including
Landlord's mortgagee) (iv) subject to any offset, defense or counterclaim that
Tenant might be entitled to assert against any previous landlord (including
Landlord's mortgagee), or (v) liable for any deposit that Tenant may have given
to any previous landlord (including Landlord's mortgagee) that has not, as such,
been transferred to said successor-in-interest. Upon request of said
successor-in-interest, Tenant shall execute and deliver an instrument or
instruments confirming such attornment.

17. COMMENCEMENT OF POSSESSION

         If the Landlord shall be unable to give possession of the Premises on
the date of the commencement of the term hereof because the Premises shall not
be ready for occupancy, the Landlord shall not be subject to any liability for
the failure to give possession on said date. Under such circumstances, unless
the delay is the fault of the Tenant, the Rent shall not commence until the
Premises are available for occupancy by the Tenant, and no such failure to give
possession on the date of commencement of the term shall in any wise affect the
validity of this lease or the obligations of the Tenant hereunder and shall not
be construed in any wise to extend the term of this lease. If, at the Tenant's
request, the Landlord shall make the Premises available to the Tenant prior to
the date of commencement of the term for the purpose of decorating, furnishing
and equipping the Premises, the use of the Premises for such work shall be
subject to all terms and conditions of the Lease except Rent, as defined m
Paragraph (b) of Section 1. If, with the consent of the Landlord, the Tenant
shall enter into occupancy of the Premises to do business therein prior to the
date of commencement of the term, all provisions of this lease shall apply and
the Rent shall accrue and be payable at the first rate specified in Paragraph
(a) of Section 1 from the date of occupancy.

18. NOTICES AND CONSENTS

         All notices, demands, requests, consents or approvals which may or are
required to be given by either party to the other shall be in writing and shall

request, bill, demand or statement, given as aforesaid to any one of such
persons shall be deemed to have been duly given to Tenant.

19. SPRINKLERS

of record, within thirty (30) days after the filing thereof, and Tenant shall
indemnify and save harmless Landlord against and from all costs, liabilities,
suits, penalties, claims and demands, including reasonable attorneys' fees
resulting therefrom.

limited to its right, title and interest in the Premises.

Kansas.

         Exhibits A, consisting of 1 pages are attached hereto and become part
of this lease.

28. NOTICE OF DEFAULT TO MORTGAGEE AND ADDITIONAL TIME TO CURE

         In the event of any act or omission by Landlord which would give the
Tenant the right to terminate this Lease or to claim a partial or total
eviction, Tenant shall not exercise any such right (a) until it shall have given
written notice, by Certified Mail, of such act or omission to the holder of any
deed of trust or mortgage encumbering the Premises whose name and address shall
have been furnished to Tenant in writing, at the last address so furnished, and
(b) until a reasonable period of time for remedying such act or omission shall
have elapsed following the giving of such notice, Landlord or said holder shall,
with reasonable diligence, have commenced and continued to remedy such act of
omission or to cause the same to be remedied. For purposes of the immediately
preceding sentence, Tenant acknowledges the holder of the Deed of Trust or
Mortgage encumbering the Premises to whom written notice is to be given is as

              105 N. Main
              Wichita, KS 67202

29. AGENCY

     Unless indicated otherwise by an attached Addendum, Tenant and Landlord
understand and acknowledge that all brokers involved in this transaction
represent the Landlord, not the Tenant; that any information disclosed by the
Tenant to any broker in this transaction has been and will be disclosed to the
Landlord; and that this agency relationship was disclosed to the Tenant when the
broker agreed to expose properties to the Tenant.

30. EXCULPATION

     The obligations of Landlord under this Lease do not constitute obligations
of the general or limited partners of the Landlord, and Tenant shall look solely
to the real estate that is the subject of this Lease and to no other assets of
Landlord for the satisfaction of any liability in respect of

<PAGE>

this Lease and will not seek recourse against the general or limited partners of
the partnership, which is Landlord herein, nor against any of their personal
assets, for such satisfaction.


31. RENEWAL

         Provided, Tenant is not in default hereunder, Tenant shall have the
right and option to extend the initial term of this lease for three (3)
additional terms of four (4) years on the same terms and conditions of this
lease except that the fixed rent as hereafter defined shall be renegotiated by
Landlord and Tenant for the option period. Said option shall be exercised by
Tenant's giving written notice upon Landlord of Tenant's intent to renew the
Lease at least one hundred eighty (180) days prior to the expiration of its
term. In the event Landlord and Tenant fail to agree upon the fixed rent within
a one hundred twenty (120) day period after written notice such option of Tenant
shall become null and void. However, for each option period, the fixed rent
shall not exceed the lesser of the following: (a) a twenty percent (20%)
increase in the fixed rent over the preceding term or option term; or (b) an
increase in the fixed rent computed as follows: the adjust shall be equal to the
increase in the "Consumer Price Index (CPI) all items" percentage as published
by the U.S. Department of Labor, Bureau of Statistics. The time period shall
include the period from the initial date of the preceding term or initial date
of the date of exercising the option by Tenant. In the event the Bureau of Labor
Statistics shall no longer publish such figures there shall be substituted the
nearest available and practical index for achieving the same purpose.
Additionally, in no event shall the fixed rent be less than the fixed rent
during the preceding term increased by twelve percent (12%).

IN WITNESS WHEREOF, Landlord and Tenant have respectively signed and sealed this
lease as of the day and year first above written.
