                                     LEASE

        THIS LEASE made and entered into this 7th day of December, 1998, by and

                                  WITNESSETH:

        For and in consideration of the rentals, undertakings and mutual
covenants hereinafter set forth, Lessor hereby leases to Lessee, and Lessee
hereby leases and hires from Lessor, subject to the terms and conditions
hereinafter expressed, the following space in that certain commercial office
building, located in Franklin, Williamson County, Tennessee, at 357 Riverside

Building which are used in common by all tenants of the Building.

        TO HAVE AND TO HOLD the Leased Premises, together with the improvements
and appurtenances thereto belonging, unto Lessee, its heirs, successors and
assigns for a term of five (5) years, commencing January 18, 1999, and ending
January 31, 2004, unless sooner terminated as hereinafter provided.

        THE PARTIES HERETO MUTUALLY COVENANT AND AGREE AS FOLLOWS, THIS LEASE
BEING EXPRESSLY SUBJECT TO THE TERMS AND CONDITIONS HEREINAFTER SET OUT:

        1. Rent. Lessee agrees to pay to Lessor for the Leased Premises during
the term hereof basic rent at the rate specified at the end of this section,
such rentals being payable in equal monthly installments. All rentals are
payable in advance on the first day of each and every month and shall be payable
without notice or demand and without deduction, set-off or abatement except as
otherwise provided specifically in this Lease. Rent for a partial month at the
beginning or end of the term shall be prorated. The basic monthly rent is as
follows: One Thousand Nine Hundred Ninety-Nine and 73/100 Dollars ($1,999.73)
for the first twelve (12) months and shall increase three percent (3%) for each
successive twelve (12) month period.

        2. Operating Expenses. For each calendar year beginning in 2000, and
thereafter, Lessee agrees to pay Lessor, as additional rent, Lessee's
"Proportionate Share" of the excess of actual "Operating Expenses" over the
"Operating Expenses" for calendar year 1999 (the

<PAGE>

"Base Year"). Lessee's Proportionate Share shall be determined by dividing the
rentable square footage of the Leased Premises by the total gross leasable area,
as determined by Lessor from time-to-time, in the Building. "Operating Expenses"
shall be defined as all operating costs of any kind and nature incurred by
Lessee in connection with the operation, maintenance or repair of the Building
and property associated therewith, including but not limited to: all cost of
casualty and liability insurance in connection with the Building, all costs of
water, sewer, electricity, gas and other utility services furnished for or
incurred in connection with the Building, all costs of janitorial and cleaning
services incurred in connection with the Building, all salaries and compensation
of employees performing services in connection with the Building, all cost of
maintenance and repair incurred in connection with the Building, the amortized
portion for the year in question of the cost of installation of capital
investment items which have the effect of reducing Operating Expenses of the
Building, all real property taxes assessed against or by virtue of the Building
and the land upon which the Building is situated, all legal, accounting and
other fees incurred in connection with the administration and operation of the
Building, cost of all ice and snow removal, the cost of parking lot sweeping,
striping and lighting, the cost of any security services provided in connection
with the Building, the cost of all supplies and materials used in connection
with the maintenance, repair and operation of the Building, all wages, including
social security, unemployment compensation, insurance and other employee
benefits and indirect compensation of employees providing services in connection
with the operation, maintenance or repair of the Building, the cost of all
contract services, including trash removal, exterminating services,
directory services, and fire extinguishers, incurred in connection with the
Building, the cost of all landscaping expenses, and an administrative fee
payable to Lessor in the amount of fifteen percent (15%) of all Operating
Expenses, all as reasonably determined by Lessor from time-to-time.

        Together with each monthly payment of the basic rental hereunder, Lessee
shall pay the Lessor as additional rent an amount equal to one-twelfth (1/12) of
Lessor's estimate, as determined by Lessor in its sole discretion, of Lessee's
Proportionate Share of the excess of $5.25 per square foot of Operating Expenses
for any year in excess of the Operating Expenses for the Base Year. As soon as
practicable following the end of each calendar year, but in no event later than
one hundred twenty (120) days after the end thereof, a final adjustment shall be
made between Lessor and Lessee based upon the actual Operating Expenses for the
preceding year. Any shortage in such amount shall be paid by Lessee to Lessor.
Any overage shall be paid by Lessor to Lessee.

        3. Leasehold Improvements. In the event Lessor and Lessee have agreed
that certain Leasehold Improvements shall be made to the Leased Premises prior
to Lessee's occupancy thereof, then the Leasehold Improvements to be made shall
be those described, if any, on Exhibit B attached hereto (the "Leasehold
Improvements"). Such Leasehold Improvements shall be made prior to the
commencement of the term of this Lease. Payment for the costs of such Leasehold
Improvements shall be made as set forth in Exhibit B. In the event Lessor is
prevented from commencement or completion of the Leasehold Improvements due to
the causes beyond Lessor's control, such as material shortages, inability to
procure contractors or laborers, casualty loss, strikes, or failure of Lessee to
make any decisions or

<PAGE>

directives required by Lessee to be made in connection with the Leasehold
Improvements, then the commencement date of the Lease term shall be extended
until completion of the Leasehold Improvements. Lessor shall have no liability
for failure to complete the Leasehold Improvements by the commencement date of
this Lease. In the event no Leasehold Improvements are to be made, then the
Leased Premises shall be taken by Lessee in its current condition on an AS IS
basis.

        4. Security Deposit. Lessee will deposit with Lessor upon the execution
of this Lease a security deposit in an amount equal to one (1) month's basic
rent. Lessee shall not be entitled to interest on the security deposit, and
Lessor may commingle such security deposit with other funds of Lessor. Upon the
termination of this Lease, provided Lessee is not in default hereunder, Lessor
shall refund to Lessee any of the then remaining balance of the deposit without
interest. In the event of a sale of the Building, Lessor may transfer the
deposit to the purchaser and be relieved of any further obligation therefor.

        5. Late Charge. Lessee shall pay a late charge equal to five percent
(5%) of any rent or other payment hereunder not paid within ten (10) days of the
due date thereof.

        6. Services Furnished. Lessor shall furnish the following services:

           (a) Entry to the Leased Premises during normal working hours on
regular business days. On other days and after normal working hours, Lessee may
gain entry to the Leased Premises at such times by a key or card-key system.

           (b) Hot and cold water at those points of supply provided for the
general use of other tenants in the Building; central heat and air conditioning
in season from 7:00 a.m. to 7:30 p.m. on business days and 7:00 a.m. to 2:00
p.m. on Saturdays, at such temperatures and in such amounts as are considered
by Lessor to be standard; but service at times during business days other than
normal business hours for the Building, additional hours on Saturdays, Sundays
and holidays or in an amount considered by Lessor to be in excess of standard
(machinery, lighting fixtures or equipment in the Leased Premises having an
electrical load in excess of four (4) watts per square foot of RA or occupancy
in excess of one person per 200 square feet of RA being conclusively presumed
to be in excess of standard) to be furnished only upon the request of Lessee,
who shall bear the entire cost thereof; routine maintenance and electric
lighting service for all public areas and special service areas of the Building
in the manner and to the extent deemed by Lessor to be standard.

           (c) Electrical facilities and sufficient power for typewriters, voice
writers, calculating and duplicating machines, desk top and small server-type
computers and other machines of similar low electrical consumption, but not
including electricity required for main frame electronic data processing
equipment and special lighting in excess of building standards, or any item of
electrical equipment which (singularly) consumes more than 0.5 kilowatts at
rated capacity or requires a voltage other than 120 volts single phases. If
Lessee uses any of the services or electrical current as enumerated in this
subsection (d) in an amount greater than 5,000 watt hours annually per square
foot of RAS or such larger amounts as may be deemed

<PAGE>

excessive by Lessor, Lessor reserves the right to charge Lessee as additional
rent a reasonable sum as reimbursement for the direct cost of such added
services. Said additional rent shall be due and payable on the dame day the
monthly basic rental is due and payable as set forth in Section 1 hereof. In the
absence of agreement as to the reasonableness of such charge, the opinion of the
appropriate local utility company or a local independent professional engineer
reasonably selected by Lessor shall prevail. Any additional equipment, feeders
or risers necessary to supply electrical requirements in excess of the amount to
be provided by Lessor pursuant to this subsection shall be supplied by Lessor at
the expense of Lessee, provided such installations will not, in Lessor's
judgment, overload the electrical system of the Building or entail excessive or
unreasonable alterations to the Building or the Leased Premises.

           (d) All building standard fluorescent bulb replacements in all areas
and all incandescent bulb replacements in public areas, toilet and restroom
areas and stairwells.

        Failure by Lessor to any extent to furnish the services described in
this Section, or any cessation thereof, resulting from the repair or alteration
of the Building or equipment for causes beyond the reasonable control of Lessor,
shall not be construed as an eviction of Lessee, nor cause an abatement of rent,
nor relieve Lessee from fulfillment of any covenant of agreement hereof.

        7. Telephone System and Service. Lessee shall use the telephone service
and system in the Building provided by Lessor as Lessee's exclusive telephone
and telecommunications provider. Attached hereto as Exhibit C is a schedule of
charges for such telephone services which shall be paid by Lessee to Lessor.
These charges may be adjusted from time-to-time by Lessor. Lessor shall submit
on a monthly basis, a bill to Lessee for telephone services and charges incurred
by Lessee for the previous month. The amount of such billing shall be payable
as additional rent hereunder within ten (10) days after submission of the bill
to Lessee. Lessee shall pay a late charge equal to five percent (5%) of any such
billing not paid within such ten (10) period.

        8. Common Area. For so long as Lessee is not in default hereunder,
Lessor grants Lessee a non-exclusive license to use and occupy, in common with
others so entitled, the common areas of the Building, including, but not limited
to, corridors, stairways, elevators, restrooms, lobbies, entranceways, parking
areas, service roads, loading facilities, sidewalks, and other facilities as may
be designated from time to time by Lessor subject to the terms and conditions of
this Lease.

        9. Card Keys. Lessor shall furnish Lessee with a minimum of six card
keys for entering the Leased Premises. Additional card keys will be furnished at
a charge by Lessor on an order signed by Lessee or Lessee's authorized
representative. All such card keys shall remain the property of Lessor. Lessee
shall not change the locks without Lessor's permission, and Lessee  shall not
make, or permit to be made, any duplicate card keys, except those furnished by
Lessor. Upon termination of this Lease, Lessee shall surrender to Lessor all
card keys to the Leased Premises and give to Lessor the explanation of the
combination of all locks for safes, safe cabinets and vault doors, if any,
installed in the Leased Premises by Lessee.
<PAGE>

        10. Graphics. Lessor shall provide and install, as an Operating Expense,
all letters or numerals on entrance doors to the Leased Premises. All such
letters and numerals shall be in the Building standard graphics, and no other

        11. Parking. Lessee shall at all times during the term of this Lease
have the right to park up to six (6) automobiles in the outdoor parking area of
the Building designated by Lessor. Parking shall be on a first come, first serve
basis and Lessor shall not be required to designate parking space for the use of
Lessee.

        12. Permitted Uses. Lessee shall use and occupy the Leased Premises only
for the following purpose: computer software development and training. Lessee
shall not occupy or use, or permit any portion of the LEased Premises to be
occupied or used, for any business or purpose which is unlawful, disreputable
or deemed to be hazardous, or permit anything to be done which would in any way
increase the rate of fire or liability or any other insurance coverage on the
Building and/or its contents, cause the load upon any floor of the Building to
exceed the load for which the floor was designed or the amount permitted by law,
or use electrical energy exceeding the capacity of the then-existing feeders or
wiring installations. Lessee shall further conduct its business and control its
agents, employees, invitees, and visitors in such manner as not to create any
nuisance, or interfere with, annoy or disturb any other tenant or Lessor in its
operation of the Building. No food, soft drink or other vending machine shall be
installed within the Leased Premises without the advance written permission of
Lessor.

        13. Compliance with Standards. Lessee shall comply with all applicable
laws, ordinances, rules and regulations relating to the use, condition or
occupancy of the Leased Premises and all common areas. Lessee shall comply with
reasonable rules and regulations as may be adopted or modified by Lessor from
time to time for the safety, care and cleanliness of the Leased Premises, the
Building and common areas and for preservation of good order therein. In
addition, the parties agree that (a) the Building is a non-smoking facility and
that no smoking shall be allowed therein at any time, and (b) that no overnight
occupancy, sleeping or lodging will be allowed on the Leased Premises at any

        14. Repairs By Lessor. Except as otherwise set forth in this Lease,

kind or character in the Leased Premises during the term of this Lease, except
such repairs as may be deemed necessary by Lessor for normal maintenance
operations required to maintain the Leased Premises in tenantable condition or
repairs previously agreed to by Lessor. Lessor shall keep in good order,
condition and state of repair the structural portions of the Building, the roof,
the plumbing, heating, air conditioning and electrical system and the common
area facilities provided by Lessor under the provisions hereof; provided,
however, Lessor's obligation to make such repairs shall not relieve Lessee of
the obligation to pay all sums which become due under this Lease. The obligation
of Lessor to maintain and repair the Leased Premises shall be limited to
Building standard items. Lessee shall reimburse Lessor upon demand for the cost
of
<PAGE>

repairing any damage to the Leased Premises or the Building caused by the
deliberate act or negligent act of Lessee or its employees, agents, invitees or
others acting on its behalf. Lessee shall, at its expense, keep in good order,
condition and state of repair all portions of the Leased Premises with the
exception of those to be maintained and repaired by Lessor under the foregoing

agents, employees, invitees, movers, visitors or others acting on its behalf. No
alterations in the Leased Premises or signs visible from outside the Leased
Premises shall be made or installed by Lessee without the prior written consent
of Lessor, which shall be in Lessor's sole and absolute discretion; and at
Lessor's election such alterations or additions shall become the property of
Lessor upon termination of this Lease.

        16. Care of Leased Premises. Lessee shall not commit or allow any waste
or damage to be committed on or to any portion of the Leased Premises, and at

Premises to Lessor in as good condition as at date of possession by Lessee, or
as the same may have been improved during the term, ordinary wear and tear or
damage resulting from fire or other unavoidable casualty excepted. If Lessee
installs improvements in the Leased Premises reasonably determined by Lessor to
be special or nonstandard, Lessor may require Lessee  to remove such special or
non-standard improvements and restore the Leased Premises to its original
condition at Lessee's sole cost and expense upon the termination of this Lease.

        17. Peaceful Enjoyment. Lessee shall have the right to peacefully
occupy, use and enjoy the Leased Premises during the lease term, subject to the

required to be paid by Lessee and performs all of Lessee's covenants and
agreements herein contained.

        18. Lessor's Right of Entry. Lessor or its agents or representatives
shall have the right to enter into and upon any part of the Leased Premises at
all reasonable hours to inspect the same, clean or make repairs, alterations or
additions thereto, as Lessor may deem necessary or desirable. Lessor further
reserves the right to show the Leased Premises to prospective tenants or brokers
during the last six (6) months of the lease term, and to prospective purchasers
or mortgagees at all reasonable times, provided prior notice is given to Lessee
in each case, and Lessee's use and occupancy of the Leased Premises shall not
thereby be materially inconvenience.

        19. Hold Harmless. Lessor shall not be liable to Lessee, or to Lessee's
agents, servants, employees, customers, invitees, or visitors for any damage to
person or property caused by any act, omission or neglect of Lessee or such
persons, and Lessee agrees to indemnify and hold Lessor harmless from all
liability and claims for any such damage. Lessee shall not be liable to Lessor,
or to Lessor's agents, servants, employees, customers, invitees, or visitors for
any damage to person or property caused by any act, omission or neglect of
<PAGE>

Lessor or such persons, and Lessor agrees to indemnify and hold Lessee harmless
from all claims for such damages.

        20. Landlord's Rights Upon Default

            (a) Each of the following events, at the option of Lessor, shall
constitute a default and breach of this Lease by Lessee: (i) if Lessee shall
fail to pay Lessor any rent or any other amount due under this Lease, within
five (5) days after the due date therefor; (ii) if Lessee shall fail to perform
or comply with any of the other terms or conditions of this Lease within ten
(10) days after notice by Lessor to Lessee specifying the term or condition to
be performed or complied with; (iii) if any proceedings are commenced by or
against Lessee in any court under any bankruptcy or insolvency act or statute,
or for the appointment of a trustee or receiver of Lessee's property; or (iv) if
the Leased Premises shall be deserted or vacated for more than five (5) days.

        In the event of any default hereunder, Lessor may, at any time
thereafter and without notice (and without prejudice to any other remedy
available to Lessor), pursue any one or more of the following remedies:

        (i) Terminate this Lease at its option and re-enter and repossess the
Leased Premises and dispossess and remove therefrom Lessee, or any other
occupants thereof, and their effects, without being liable for any prosecution
therefor. In such event, Lessee shall be liable to Lessor, immediately and upon
demand, for the amount of all loss and damages suffered by Lessor by reason of
such termination, whether caused by the inability to relet the Leased Premises
on satisfactory terms or otherwise;

        (ii) Enter upon and take possession of the Leased Premises without
terminating this Lease and without relieving Lessee of Lessee's obligations to
make all payments of rent and all other sums owed hereunder. In such event,
Lessor may dispossess and remove therefrom Lessee, or any other occupants
thereof, and their effects, without being liable for any prosection therefor;
and Lessor may, at its opinion, relet the Leased Premises or any part thereof,
as the agent of Lessee, and Lessee shall, immediately and upon demand, pay the
difference between the rent and other costs and charges herein reserved and
agreed to be paid by Lessee for the portion of the term remaining at the time of
re-entry or repossession and the amount, if any, received or to be received
under such reletting for such portion of the term; or

        (iii) Exercise all other rights and remedies available to Lessor
hereunder and at law or in equity.

        All actions taken by Landlord pursuant to this Section shall be without
prejudice to any other remedies that otherwise might be available under this
Lease or applicable law.

              (b) Any property which may be removed from the Leased Premises by
Lessor pursuant to the authority of this Lease or of law, to which Lessee is or
may be entitled, may be handled, removed or stored by Lessor at the risk, cost
and the expense of Lessee, and

<PAGE>

Lessor shall in no event be responsible for the value, preservation or
safekeeping thereof. Lessee shall pay to Lessor, 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 Lessor's possession or under Lessor's control.
Any such property of Lessee not retaken from storage by Lessee within thirty
(30) days after the end of the lease term, however terminated, shall be
conclusively presumed to have been conveyed by Lessee to Lessor under this
Lease as a bill of sale.

            (c) In the event Lessee defaults in the performance of any of the
terms, covenants, agreements or conditions contained in this Lease and Lessor
places the enforcement of this Lease, or any part thereof, or the collection of
any sums due or to become due hereunder, or recovery of the possession of the
Leased Premises, in the hands of an attorney, or files suit upon the same,
Lessee agrees to pay Lessor's reasonable attorneys' fees.

            (d) Failure of Lessor to declare any default immediately upon
occurrence thereof, or delay in taking any action in connection therewith, shall
not waive such default, but Lessor shall have the right to declare any such
default at any time and take such action as might be lawful or authorized
hereunder, either at law or in equity.

        21. Holding Over. If Lessee retains possession of the Leased Premises or
any part thereof after the termination of this Lease, Lessee shall pay rent at
double the basic rate payable on the month preceding such holding over computed
on a daily basis for each day that Lessee remains in possession. In addition
thereto, Lessee shall be liable for, and pay to Lessor, all damages,
consequential as well as direct, sustained by reason of Lessee's holding over.

        22. Condemnation. If the Leased Premises shall be partially taken or
condemned for any public purpose to such an extent as to render a portion of the
Leased Premises untenantable, the rental provided for herein shall abate as to
the portion rendered untenantable. In the event the whole of the Leased Premises
shall be so taken or condemned, this Lease shall terminate as of the date of
taking of possession. All proceeds from any taking or condemnation of the Leased
Premises shall belong to and be paid to Lessor.

        23. Damage or Destruction.

            (a) Total Destruction. If the Leased Premises are damaged or
destroyed by fire, earthquake or any other casualty to such an extent as to
render the same untenantable in whole or in substantial part, Lessee shall give
Lessor immediate notice of the occurrence of such casualty. Unless Lessor
notifies Lessee within sixty (60) days after receipt of such notice of its
election to repair or to restore the Leased Premises, this Lease shall terminate
at the end of such thirty-day period. If Lessee shall not be in default under
this Lease, then Lessee's liability for rent shall cease as of the day following
the casualty and any rent paid by Lessee in advance and not yet earned as of
the date of termination shall be refunded to Lessee. Should Lessor elect to
repair and/or restore the premises, Lessor must notify Lessee of such decision
within sixty (60) days of date of loss. If Lessor elects to so repair the Leased
Premises it will
<PAGE>

do so within one hundred eighty (180) days and the rent shall be abated during
the period of repair or restoration in the same proportion as the untenantable
portion of the Leased Premises bears to the former leasable area of the Leased
premises. If more than twenty five percent (25%) of the leasable square feet in
the Building are damaged or destroyed by fire, earthquake or any other casualty,
then Lessor, at its sole option, may terminate this Lease upon notice to Lessee.

            (b) Partial Destruction. In the event the Leased Premises are
damaged by fire, earthquake or any other casualty to such an extent that it is
not rendered untenantable in whole or in substantial part, then Lessor shall
promptly repair and restore the Premises. The rent shall be abated
proportionately as to the portion of the Leased Premises.

        24. Insurance. Lessor shall maintain fire and extended coverage
insurance on the Building in which the Leased Premises are located. Said
insurance shall be maintained with an insurance company authorized to do
business in Tennessee in amounts desired by Lessor and at the expense of Lessor,
and payments for losses thereunder shall be made solely to Lessor. Lessee shall
be responsible for its own insurance coverage on its personal property. If the
premiums to be paid by Lessor shall exceed the standard rates because of
Lessee's operations, or contents of the Leased Premises, or improvements made to
the Leased Premises by Lessee, Lessee shall promptly pay the excess amount of
the premium upon request by Lessor as additional rent.

        25. Waiver of Subrogation. Anything in this Lease to the contrary
notwithstanding, to the extent such a waiver does not void any applicable
insurance coverage, Lessor and Lessee each hereby waive any and all rights of
recovery, claim, action or cause of action, against the other, its agents,
officers, or employees, for any loss or damage that may occur to the Leased
Premises, or any improvements thereto, or to the Building of which the Leased
Premises are a part, or any improvements thereto, or any personal property of
such party therein, by reason of fire, the elements, or any other cause to the
extent that such rights of recovery, claim, action or cause of action are
covered by insurance, regardless of cause or origin, including negligence of the
other party hereto, its agents, officers or employees, and each covenants that
no insurer shall have any right of subrogation against such other party.

        26. Assumption of Risk. Lessee shall, and does hereby, assume all risks
of loss or injury to the property or person of all persons at any time coming
upon the Leased Premises during the term hereof, and Lessee shall, and does
hereby agree to, indemnify and save harmless Lessor for and from any and all
claims, demands, suits, judgments, costs or expenses on account of any such loss
or injury; and to that end, Lessee shall, at its own cost and expense, maintain
general public liability insurance for and on the leased premises, naming itself
and Lessor as insured parties, with limits of not less than $1 million combined
single limit for bodily injury and property damage. Such insurance shall be
effected by a valid and enforceable policy issued by an insurance company of
recognized responsibility doing business in the State of Tennessee and shall
contain a provision that coverage cannot be cancelled without ten (10) days'
written notice to Lessor. Lessee shall furnish to Lessor a copy of such

<PAGE>

policy and a certificate evidencing that the required insurance is in full force
and effect and showing Lessor as additional insured thereon.

        27. Subordination, Non-Disturbance and Attornment. Lessee agrees that
its rights hereunder shall be subordinate to any mortgage or deed of trust, or
the lien resulting from any other method of financing or refinancing, now or
hereafter in force against the Building. Notwithstanding the forgoing, Lessee's
right to quiet enjoyment of the Leased Premises shall not be disturbed if Lessee
is not in default under the provisions of this Lease. Lessee agrees upon
Lessor's request to execute any subordination agreement requested by Lessor's
mortgage lender(s).

        28. Estoppel Certificate. Lessee shall at any time, upon not less than
ten (10) days prior written request, execute and deliver in form and substance
satisfactory to Lessor and any mortgagee or beneficiary under a mortgage or deed
of trust affecting the Leased Premises an estoppel certificate certifying:

            (a) The date upon which the lease term commences and expires;

            (b) The date to which rent has been paid;

            (c) That Lessee has accepted and is occupying the Leased Premises;

            (d) That the Lease is in full force and effect and has not been
modified or amended (or if modified or amended, a description of same);

            (e) That there are no defaults by Lessor under the Lease nor any
existing condition with respect to which the giving of notice or lapse of time
would constitute a default;

            (f) That Lessee has received no notice from any insurance company of
any defects or inadequacies in the Leased Premises;

            (g) That Lessee has no options or rights other than as set forth in
this Lease or any amendment thereto described in such letter; and

            (h) Such other matters as may be necessary or appropriate to qualify
Lessee's response to any of the foregoing statements or which Lessor may
reasonably request.

If such certificate is to be delivered to a purchaser of the Building, it shall
further include the agreement of Lessee to recognize such purchaser as Lessor
under this Lease, and thereafter to pay rent to the purchaser or its designee in
accordance with the terms of this Lease. Lessee acknowledges that any purchaser
or prospective mortgagee of the Building may rely upon such estoppel letter and
that Lessor may incur substantial damages by reason of any failure on the part
of Lessee to provide such letter in a timely manner.

<PAGE>

        29. Environmental Matters. The term "hazardous substances," as used
herein shall mean pollutants, contaminants, toxic or hazardous wastes or any
other substances the use and/or the removal of which is restricted, prohibited
or penalized by any "environmental law," which term shall mean any federal,
state or local law, ordinance or other statute of a governmental authority
relating to pollution or protection of the environment. Lessee hereby agrees
that (a) no activity will be conducted on the Leased Premises that will produce
any hazardous substance; (b) the Leased Premises will not be used in any manner
for the storage of any hazardous substances; (c) Lessee will not install or
place upon the Leased Premises any underground or above ground tanks of any type
and will not store, or allow the storage of, on the Leased Premises any
gasoline, oil, diesel fuel or other petroleum products; (d) Lessee will not
allow any surface of subsurface conditions to exist or come into existence that
constitute or with the passage of time may constitute a public or private
nuisance; and (e) Lessee will not permit any hazardous substances to be brought
into the Leased Premises. If at any time during or after the term of this Lease,
the Leased Premises are found to be in violation of any of the covenants set
forth in this section due to acts or occurrences during the occupancy of Lessee,
or caused by Lessee, then Lessee shall diligently institute proper and thorough
cleanup and remediation procedures at Lessee's sole cost. Lessee agrees to
indemnify and hold Lessor harmless from all claims, demand, actions,
liabilities, costs, expenses (including Lessor's attorney fees), damages and
obligations of any nature arising from or as a result of the use of the Leased
Premises by Lessee. The foregoing indemnification and the responsibilities of
Lessee shall survive the termination or expiration of this Lease. Lessee has
inspected the Leased Premises and to the best of Lessee's knowledge the Leased
Premises are free from environmental contamination at the execution of this
Lease.

        30. Limitation of Liability. Notwithstanding any provision in this Lease
to the contrary, under no circumstances shall Lessor's liability or that of its
directors, officers, employees and agents, for failure to perform any
obligations arising out of or in connection with the Lease or for any breach of
the terms or conditions of this Lease (whether written or implied) exceed
Lessor's equity interest in the Building. Any judgments rendered against
Landlord shall be satisfied solely out of proceeds of sale of Lessor's interest
in the Building. No personal judgment shall lie against Lessor upon
extinguishment of its rights in the Building and any judgments so rendered shall
not give rise to any right of execution or levy against Lessor's assets.

        31. Lessor's Right to Perform. If Lessee shall default in the
performance of any covenant or condition of this Lease required to be performed
by Lessee, Lessor may, at its option, perform such covenant or condition for the
account and at the expense of Lessee. The amount of any expense so incurred
shall be deemed additional rent and may, at the option of Lessor, be added to
any subsequent installment of the net monthly rent due and payable under this
Lease, in which event Lessor shall have the remedies for default in the payment
thereof provided by this Lease. The provisions of this paragraph shall survive
the termination of this Lease.

        32. No Waiver. The failure of Lessor or Lessee to insist upon a strict
performance of any term or condition of this Lease shall not be deemed a waiver
of any right or remedy that
<PAGE>

Lessor or Lessee may have and shall not be deemed a waiver of any subsequent
breach of such term or condition.

        33. Landlord-Tenant Relationship. It is expressly agreed and understood
that Lessor shall not be construed or held to be a partner or associate of
Lessee in the conduct of its business, it being expressly understood and agreed
that the sole relationship between the parties hereto is that of landlord and
tenant.

        34. Assignment, Sublease, Transfer of Ownership Interest. There shall be
no assignment or subletting of this Lease, and there shall be no transfer of any
ownership interest in Lessee (if Lessee is other than a natural person), without
securing the prior written consent of Lessor, which shall be in Lessor's sole
discretion. It is understood and agreed that Lessee shall remain fully liable on
the Lease in such event and that any assignee or sublessee shall be bound by all
the terms and provisions of this Lease.

        35. Notices. All notices and other communications to be given hereunder
by either party shall be in writing and shall be delivered personally, forwarded
by nationally recognized overnight express delivery service, or mailed, postage
prepaid, by first class mail to the other (and the date of any notice by
certified or registered mail shall be deemed to be the date of certification or
registration thereof) delivered or addressed to the parties as follows:

or at such other address as either party may later designate in writing.

        36. General Provisions. The entire agreement between the parties hereto
is contained in this instrument and it is expressly agreed that no obligations
of Lessor or Lessee shall be implied in addition to those herein expressly
contained. Any amendment to this Lease must be in writing signed by the parties
hereto in order to be binding. The terms and provisions of this Lease shall be
binding upon and inure to the benefit of the parties hereto and to their
respective heirs, successors and assigns. This Lease shall be governed in
accordance with the law of the State of Tennessee. Captions herein are for
convenience only and shall not limit the scope or intent of the provisions of
this instrument. This instrument is severable such that the invalidity or
unenforceability of any provision hereof shall not impair the validity or
enforceability of the remaining provisions.

written have executed this Lease in duplicate, with a copy to be retained by
each of the parties.

by FERRARI PARTNERS, L.P. ("Landlord"), to CONNECTED SOFTWARE SOLUTATIONS, LLC
("Tenant"), pursuant to Lease of even date herewith (the "Lease"), entered into
between Tenant and Landlord, the undersigned Roger Barnes ("Guarantor"), hereby

with or without having commenced any action against or having obtained any
judgment against the Tenant, or any successor or assign thereof.

     This Guaranty inures to the benefit of Landlord, its successors and
assigns, and is binding upon the Guarantor and the heirs, successors, and
assigns thereof.

V.  DEFINITIONS

Sun Companies refers to Sun Microsystems, Inc. and all of its subsidiaries,
business units, and divisions worldwide.

Sun Trademarks refers to all subsidiary, business unit, and division names,
product names, service names, program names, logos, slogans, trade dress, and
all other designations used by any Sun Company, including but not limited to the
Sun Logo, Special Program Logos, and Sun Trade Dress.

Sun Logo is the Sun Corporate Logo consisting of the diamond-shaped graphic (the
"Sun Bug") next to "Sun Microsystems."

<PAGE>

Special Program Logos are the official logos provided by any Sun Company to Sun
developers, resellers, and other third parties participating in Sun marketing
programs, e.g., the Sun Authorized Reseller Logo or the Catalyst Developer Logo.
[For further information regarding use of Special Program Logos, see p. 9.]

Sun Trade Dress refers to the overall appearance of Sun's product packaging and
to the overall external product design of Sun's products, including distinctive
features such as the Sun Blue color, the Solaris sunburst design, and the dimple
pattern, pizza box shape, pedestal feet, and shark fin elements of Sun systems.

VI.  PROPER TRADEMARK USE & ATTRIBUTION

A.  Rules of Proper Trademark Use
Trademarks are adjectives -- not nouns or verbs.  Accordingly, a trademark
should not be used alone, as a noun.  Rather, as often as possible, a trademark
should be used as an adjective immediately preceding the generic noun that
describes the product in question. For example:

                             Sun(TM) workstation
                             Solaris(TM) software environment
                             SPARCstation(TM) 20 system
                             Netra(TM) Internet server
                             Sun(TM) system

This rule must be followed upon the first use of the mark in text or body copy,
and periodically thereafter.  However, it need not be followed in headlines,
package titles, labels, or documentation titles.
To summarize the basic use rules:

      Use as an Adjective:                 A trademark must be used as an
                                           adjective followed by a generic noun
                                           upon first use in text and
                                           periodically thereafter. It need not
                                           be followed by the generic noun in
                                           headlines, package titles, labels, or
                                           documentation titles.
      No Possessives:                      Since a trademark is not a noun, it
                                           must never be used in possessive
                                           form.
      No Plurals                           Since a trademark is not a noun, it
                                           must never be used in plural form.
      No Verbs:                            Since a trademark is not a verb, it
                                           must never be used as a verb.
      No Puns:                             Sun's trademarks are Sun's brands,
                                           the symbols of Sun goodwill
                                           worldwide. They should be treated
                                           with respect as valuable corporate
                                           assets. Accordingly, they should not
                                           be used as the object of puns, e.g.,
                                           "Make your Sun shine."

<PAGE>

B. Proper Trademark Attribution
Trademark ownership is attributed in two ways, with the use of a trademark
symbol(TM, SM) or (R) after the trademark, and with a trademark legend, usually
found at the end of a document in mouseprint following the copyright notice.
Following are Sun's rules for use of its trademark symbols and legends.

Trademark Symbols:

Which Symbol Do I Use?
Even though many of Sun's marks are registered in the U.S. and abroad, Sun uses
the (R) symbol only with the Sun Logo. All other trademarks should have the (TM)
or (SM)symbols for trademarks and service marks, respectively. A trademark is a
mark used on or in connection with a tangible product, e.g., a Sun(TM)
workstation or the Solaris(TM) software environment. A service mark is used in
connection with the provision of services, e.g., the SunSpectrum(SM) service
program.

Where Do I Place the Symbol?
The symbol is placed immediately after the trademark, either in superscript or
subscript. If you don't have the appropriate symbol keys in your word processing
software, then using the symbols in parenthetical form is also okay, e.g., (SM)
or (TM). The symbol is generally placed before any model designation, although
not always. And some marks require more than one symbol. Please consult Tmark,
Sun's on-line trademark database (just type "tmark &" in a shelltool), for a
complete, up-to-date list of Sun trademarks along with their appropriate symbols
and attributions. Updated hard copies of the list are available directly from
the Sun Trademark Group.

When Do I Use the Symbol?
Follow these rules to determine when use of a trademark or service mark symbol
is required:

          Most Prominent Uses: All Java based marks must bear a trademark symbol
          on all prominent uses, including advertising and press release
          headlines. For all other Sun Trademarks, a trademark symbol is
          required for all prominent use of the mark, e.g., labels, packaging,
          promotional brochures, data sheets, etc., except prominent uses in
          press releases and advertisement headlines.

          First Use in Text: A trademark symbol is required upon the first use
          of the mark in any text or body copy, even though the symbol may have
          already been used in the headline or other prominent use.

          All Logos: Trademark symbols are required for all Sun Trademarks in
          logo format, e.g., The Sun Logo, the Java Coffee Cup Logo, the
          UltraSPARC Driven Logo, etc.

<PAGE>

Trademark Legends:
All Sun and SPARC trademarks that are used in a particular piece must be
attributed in an appropriate trademark legend. The legend may be presented in
"mouseprint" but must be large enough to be legible. It generally appears at the
end of a document or on the back of a package, but it may be placed elsewhere,
e.g., the front inside cover of documentation, or the bottom of a Web page.

Sun uses a standard trademark legend that does not change except to add the
marks that are referenced in the text. The legend is constructed out of the
standard copyright notice (consult your OpCo or Geo counsel) followed by two
separate trademark legends: the Sun Legend, and the SPARC Legend where SPARC
trademarks are referenced in the materials.

Sun Legend: Following is the standard Sun Legend to be used in all material
referencing any Sun Trademark:

          "Sun, Sun Microsystems, the Sun Logo [insert all other Sun trademarks,
           Special Program Logos, Product Names, Service Names, Program Names,
           and slogans that are referred to or displayed in the document] are
           trademarks or registered trademarks of Sun Microsystems, Inc. in the
           United States and other countries."

[Note: The Sun, Sun Microsystems, and Sun Logo marks are included in every
trademark legend regardless of whether they are referenced or displayed and
regardless of the Sun Company preparing the document.]

SPARC Trademark Legend: Following is the standard legend to be used in all
material referencing any SPARC trademark:

          "All SPARC trademarks are used under license and are trademarks or
          registered trademarks of SPARC International, Inc. in the United
          States and other countries. Products bearing SPARC trademarks are
          based upon an architecture developed by Sun Microsystems, Inc."

Example Legend: Following is an example of a complete trademark legend where
SPARC trademarks are referenced. Note that the specific Sun marks used in the
document must be inserted into the Sun portion of the legend, whereas the SPARC
portion of the legend never changes.

          Sun, Sun Microsystems, the Sun Logo, SunSoft, Solaris, Java and Netra
          are trademarks or registered trademarks of Sun Microsystems, Inc. in
          the United States and other countries. All SPARC trademarks are used
          under license and are trademarks or registered trademarks of SPARC
          International, Inc. in the United States and other countries. Products
          bearing SPARC trademarks are based upon an architecture developed by
          Sun Microsystems, Inc.
<PAGE>

Attribution of Third-Party Marks: Sun's general rule is not to attribute any
third-party marks except in certain special cases, such as where we have
contractually agreed to do so. Accordingly, as a general rule, trademark symbols
and legends should not be used with third-party marks. Similarly, a "generic" or
"catch-all" legend should not be used to attribute third-party marks.

Third-party marks that Sun is required to attribute appear in Tmark. If you
believe a third-party mark should be attributed, consult Tmark. If the mark
appears in Tmark, then use the appropriate trademark symbol and attribute the
mark in the legend. If you believe it may be necessary for Sun to attribute a
third-party mark that does not appear in Tmark, or if you are negotiating a
contract that includes a provision requiring Sun to acknowledge or attribute a
third party's trademarks, please contact the Sun Trademark Group and/or your
OpCo legal counsel right away for further guidance.

VII. Sample Advertising Copy
This example illustrates proper trademark use and attribution in a Sun
promotional brochure or advertisement. The same policies apply to Sun reseller,
developer, or other third-party ads using Sun trademarks. See footnotes for
explanation.
================================================================================

                       Which Would You Rather Go Through
                            To Get On The Internet?
                        The Netra(TM) Internet server.
                First in a line of new Netra servers from Sun.
This one's a no-brainer. Buy a Sun(TM) Netra(TM) server. Plug it in. And in
about half an hour your company is on the Internet. You can perform this seeming
sleight of hand because Sun Netra servers are the only servers that come
complete and preconfigured for the Internet.

                    [Logo of Sun Microsystems appears here]

(c) 1994 Sun Microsystems, Inc. All Rights Reserved. Sun, Sun Microsystems, the
Sun Logo, Netra, and The Network Is The Computer are trademarks or registered
trademarks of Sun Microsystems, Inc. in the  United States of America and other
countries.
================================================================================

<PAGE>

Footnotes
The Netra mark is used prominently in a headline, and must therefore have a
trademark symbol after it. It must also be marked with a symbol upon its first
use in body copy, as shown; but not thereafter. Similarly, the Sun mark is
marked with a symbol upon its first use in body copy. The Network is the
Computer is also marked upon its first and most prominent use. The Sun Logo
requires a trademark symbol. All product marks are followed by the appropriate
generic term, e.g. "server" for the Netra mark. Use of the generic "server" is
required on the first reference in body copy, as shown. Here the generic is also
used in the headline and in subsequent references in body copy -- this is
desirable, but not required. The trademark legend attributes all marks used in
the advertisement, as well as the Sun Microsystems mark which is not used but
which is always attributed in every legend (along with the Sun and Sun Logo
marks, whether or not they are actually used). No SPARC marks are attributed
since none are used, but if they were used, the appropriate additions to the
trademark legend would be necessary.

VIII. Sample Press Release Copy
Following are three samples of the same third party press release: the first
demonstrates incorrect trademark use, the second highlights the trademark
misuses, and the third demonstrates proper trademark use.

Incorrect trademark use in a press release

3-D modeling system runs on all SPARC(TM) systems, including Sun systems.

IX. Third-Party Use of Sun Trademarks
Only certain, approved uses of Sun Trademarks may be made by Sun business
partners and other third parties. Unauthorized use of Sun Trademarks or of marks
that are confusingly similar to Sun Trademarks may constitute an infringement of
Sun's trademark rights. Following are Sun's general policies regarding third-
party uses of Sun Trademarks.

A. No Use of Sun Marks in Third-Party Company or Product Names.
Third parties generally may not use the Sun mark, the Java mark, the Solaris
mark, or any other Sun Trademark as all or part of their company or product
names. This is especially true of Sun's business allies, such as resellers and
ISVs, who sometimes wish to leverage off of Sun's marks by including Sun or
Java or Solaris in their product or company names. Whether a particular use is
permissible will depend on the circumstances of the use. Accordingly, any such
use or proposed use should be reported immediately to the Trademark Group for
appropriate further action.

B. No Use of Sun Trade Dress by Third Parties. Third parties generally are
prohibited from using Sun Trade Dress (see Definitions) for their own products,
including any of the distinctive ornamental features of Sun products and
packaging such as the Sun Blue color, dimple patterns, blue pedestal feet, shark
fins, the Solaris sunburst design, and the like. Any such use must be approved
by Sun Legal.

C. Promptly Report Suspected Infringements. Promptly report any possible
infringement of Sun Trademarks or Trade Dress to Sun Trademark Counsel. Any
unauthorized use of a Sun Trademark or a mark that is confusingly similar to a
Sun Trademark should be reported immediately. Please provide as much detail as
possible regarding the identity of the possible infringer and well as the
suspected infringing use.

D. Proper References to Sun Products Okay.
Of course, third parties may use Sun Trademarks to refer to Sun products, so
long as Sun's marks are used properly as adjectives and are used with the proper
trademark symbols and legends (as discussed in Section VI above). For example, a
reseller will obviously use Sun Trademarks in its advertisements to advertise
the Sun products that bear those trademarks - this is entirely acceptable so
long as the reseller properly uses the marks and the appropriate trademark
symbols and legend. Similarly, while an ISV is not permitted to indicate that
its software is intended for Sun systems by incorporating Sun or Solaris or Java
in the name of its software product, it may use a tagline that truthfully
states that the product is for Sun systems or for the Solaris or Java
environments. For example:

<PAGE>

Right:    Techna/G(TM)
          For the Solaris(TM) Software Environment

          Techna/G(TM)
          Java(TM) Edition

Wrong:    Techna/G(TM) for Solaris

          Techna/G: Solaris Version 2.3

          SunTechna/G

          Techna/G
          Solaris Compatible

          TechnaJava

          Techna/G

          Java Compatible

When using a tagline to indicate that the product is for use with Sun systems or
software, the tagline must be presented in typeface that is significantly
smaller than that used for the product and/or company names of the third party--
the third party's own product and company names should be displayed much more
prominently than any Sun Trademark referenced.

E. No Use of Sun Logos, except Special Program Logos.
Sun's third-party business allies (e.g., resellers, ISVs, independent sales or
service organizations) may not use the Sun Logo as part of their own logo or
otherwise, except that they may use Special Program Logos ("SPLs") subject to
the following guidelines and restrictions.

       l. Approved Format Only. Special Program Logos or SPLs have a consistent
format throughout Sun, cross-OpCo and cross-Geo. In a box, they contain the Sun
Logo and a description of the third-party relationship to Sun. The entire SPL is
always rendered in black (not Sun Blue.) Following are samples of SPLs which an
authorized reseller could use for any Sun business unit:
<PAGE>

[Logo of Sun Microsystems                           [Logo of Sun Microsystems
      appears here]                                       appears here]
    AUTHORIZED RESELLER                                  MASTER RESELLER

[Logo of Sun Microsystems                          [Logo of Sun Microsystems
      appears here]                                       appears here]
    SYSTEM INTEGRATOR                                  VALUE ADDED RESELLER

     New SPLs for new programs may be created by Sun marketing organizations as
needed, as long as the new SPL follows the above format and clearly describes
the relationship between Sun and the ally in the lower half of the box. New SPLs
need to be approved in advance by the Sun Trademark Department.

     2. No Alterations. Sun third-party business allies must obtain SPL
camera-ready artwork directly from their Sun marketing representative, and may
not alter SPLs in any way.

     3. Pre-Sale Marketing Materials Only. SPLs may be used only in pre-sale
marketing materials such as advertisements and other promotional materials,
e.g., company brochures, catalogs, product collateral, and the like. They may
also be displayed on the ally's business cards and letterhead. SPLs may not be
displayed on products, product labels, product packaging, documentation, or any
materials accompanying products at or after the point of sale.

     4. Display of SPLs. Any material in which an SPL is displayed must also
prominently display the business ally's own name and logo. The SPL must be
displayed in a size and manner that is smaller and less prominent than the
business ally's own name and logo.

     5. Signed Contract Required. Permission to use an SPL must be granted in
writing in a binding agreement signed by both parties. In most cases, SPL
permission will be granted in the reseller agreement or other agreement
governing the relationship between Sun and the business ally. Contact Sun
Trademark Counsel for the appropriate contract language.

<PAGE>

F. Legal Approval Required for All Other Branding and Logo Programs. Any other
branding or logo programs that do not meet the precise SPL criteria described
above must be approved in advance by the Sun Trademark Group. Specifically, this
includes compatibility logos for ISVs and IHVs and special partner logos that do
not follow SPL format or use rules. It is advisable to involve the Sun Trademark
Group as early as possible in the planning stages for any such program because
such programs present uniquely complex legal issues as well as potentially high
administrative costs. Working through these issues can take time.

G. No Re-Logoing, Co-Logoing, or Logo Removal. Resellers of Sun products may
never alter or modify the Sun Logo or Sun Trademarks that are affixed to or
appear on the Sun products they resell. Similarly, re-logoing (replacing Sun's
Trademarks with the reseller's logo or mark) and co-logoing (adding the
reseller's logo or mark to the Sun product) are generally contrary to Sun policy
and will be approved only in exceptional cases. Advance approval for re-logoing
and co-logoing must be obtained from the Sun Trademark Group and from senior
sales and marketing management. Please contact the Sun Trademark Group for
further information.

X. New Marks and Names -- Legal Review Process

All new names, marks, and logos to be adopted by any Sun OpCo, subsidiary,
division, business unit or Geo must receive legal review before adoption.
Specifically, all of the following must receive legal review by the Trademark
Group:

          Product Names
          Product Line Names
          Company, Opco, and Division Names
          Service Names
          Name Extensions (extension of an existing name
          to additional Sun products)
          Names licensed to Sun by others
          Program Names
          Feature Names
          Slogans and Taglines
          Catch Phrases
          Logos
          Package Designs
          Model Numbers and other Model Designations
          Abbreviations and Acronyms
          Internet Domain Names (primary and secondary)
          Web GIFs
          File Names (for on-line software distribution)
          Compatibility Logos
          Special Program Logos
          Partner Brands

Legal review of new names and marks can easily take up to six months or more
under some circumstances. Accordingly, it is imperative that the legal review
process be started

       stating the date of sale, and, if applicable, the serial number of
       Products sold. IVAR shall, during the term of this Agreement and for five
       (5) years thereafter, keep and maintain complete and accurate business
       records with respect to its purchase and sale of all Products, including,
       all documents relating to or exchanged between IVAR and its End Users,
       Master Reseller and Sun, Sun may review these records upon request.

       IVAR shall provide monthly Productivity Status Reports ("PSRs")to Sun as
       detailed in the Guide. Upon the initial failure to timely submit a
       complete PSR, Sun will put IVAR on notice that it is in breach of its
       obligation. If IVAR fails to remedy this initial breach or subsequently
       fails to timely submit a PSR, Sun may cancel RDF accruals and suspend
       participation in other programs. Any subsequent failure to remedy or
       timely submit a PSR may result in immediate termination of this
       Agreement.

   D.  Indemnity and Insurance. IVAR agrees to indemnify and hold Sun harmless
       from and against all claims from IVAR's End Users or third parties
       arising out of any acts and/or omissions of IVAR or its employees or
       representatives. IVAR shall carry liability insurance to protect Sun from
       all such claims, pay the premiums therefor, and deliver to Sun, upon
       request, proof of such insurance (which shall require thirty (30) days'
       written notice to Sun in event of modification or termination).

   E.  Fair Representation. IVAR shall display, demonstrate, and represent
       Products fairly and shall make no representations concerning Sun or its
       Products which are false, misleading, or inconsistent with those
       representations set forth in promotional materials, literature and
       manuals published and supplied by Sun. IVAR shall comply with all
       applicable laws and regulations in performing under this Agreement.

                                ADDENDUM TO THE
                     SUN MICROSYSTEMS COMPUTER CORPORATION
            U.S. INDIRECT VALUE ADDED RESELLER ("IVAR") AGREEMENT

This Addendum, effective on January 1, 1994, is entered into by and between Sun
Microsystems Computer Corporation ("SMCC") and Design Automation Systems, Inc.,
who are parties to a U.S. Indirect Value Added Reseller ("IVAR") Agreement No.
iv-002750TP (the "Main Agreement").

The provisions of the Main Agreement are hereby modified as follows:

A.  SECTION 1; SCOPE.

    Delete the parenthetical "(identified by 'Product Tiers')" in second
    sentence.

B.  SECTION 2; APPOINTMENT.

    Delete the text of Section 2 and substitute in its place the following:

        "Sun appoints Reseller as a non-exclusive Indirect Value Added Reseller
        ("IVAR"), IVAR is authorized to purchase Product from its designated
        Master Reseller. Product must be:

        "(i)    sold, leased or rented (collectively referred to as 'sold') in
        conjunction with the services and/or products set out on Exhibit B
        (collectively referred to as 'Value Added Services');

        "(ii)   sold directly to End Users on a face-to-face basis; and

        "(iii)  installed at an End User site in the United States ('Authorized
        Sale').

        "The sale of Products to resellers is prohibited. The sale of [partially
        illegible] Products to the Federal Government is prohibited unless IVAR
        executes a Government System Integrator (GSI) Addendum. IVAR's primary
        business must at all times be the sale and support of computer systems
        and related Added Value Services.

        "IVAR has executed the "Representation and Warranty" attached as Exhibit
        E, thereby representing and warranting that it currently operates under
        (or will establish no later than July 1, 1994), and will maintain for
        the remainder of the term of this Agreement, a business model so that at
        least fifty percent (50%) of IVAR's aggregate revenue for any six month
        period is generated by the sales of Value Added Services. IVAR agrees,
        upon reasonable notice and at its own expense, to provide to SMCC in
        confidence, financial reports and documentation sufficient to establish
        that it is in conformity with this Representation and Warranty. SMCC
        reserves the right, upon reasonable notice and at SMCC's expense, to
        audit IVAR's conformity."

C.  SECTION 3; RESELLER DEVELOPMENT FUNDS.

    Insert before the period at the end of the first sentence (after the word
    'resale'), the following:

        "and Products that IVAR's Master Reseller did not purchase from SMCC"

D.  SECTION 4; BUSINESS PLAN.

    Delete the text from the beginning of the second sentence to the end of the
    Section and substitute in its place the following:

        "Either party may initiate a review of IVAR's compliance with its
        Business Plan upon thirty (30) days' notice, provided that SMCC shall
        initiate no more than one review per calendar quarter. IVAR's failure to
        comply with its Business Plan will constitute a material breach of this
        Agreement."

E.  SECTION 8, IVAR'S OBLIGATIONS.

    Insert new Subsection C as follows (and redesignate the remaining
    Subsections accordingly):

        "C.  UPGRADES. The list price of upgrades is based upon the return to
        SMCC of specified parts from the system(s) being upgraded, as set out in
        the U.S. Price List. IVAR is responsible for assuring that the specified
        parts are received by SMCC within thirty (30) days after shipment of the
        upgrade to IVAR. If the specified parts are not timely received, Master
        Reseller will invoice and IVAR agrees to pay Master Reseller (net 20
        days) for the non-returned parts, the difference between the list price
        of the purchased upgrade(s) and the list price of the upgraded system(s)
        if purchased new."

F.  SECTION 12; TERM AND TERMINATION

    Insert before the period at the end of Subsection B(2) the following:

        "or (iv) IVAR fails to maintain the business model as set out in
        Section 2."

G.  EXHIBIT A; PRODUCT TIERS/AUTHORIZED LOCATIONS/MASTER RESELLER.

    Delete all references to "Product Tiers" and related text, and substitute in
    its place the following:

        "Products IVAR may purchase for resale only Products for which it has,
        at the time of purchase, established the required level of training and
        certification. SMCC reserves the right to discontinue any Product upon
        sixty days' notice."

H.  EXHIBIT B; ADDED VALUE

    Delete the text of Exhibit B in its entirety and substitute in its place the
    following:

        "Value 'Added Services' means:

        "1.     Services such as installation, training, consulting,
                integration, system management, and software maintenance.

        "2.     Products such as proprietary/customized software and
                proprietary/customized hardware peripherals/add-one; but NOT
                widely available general purpose products that are
                undifferentiated by channel, such as word processing and spread
                sheet applications, and generic hardware peripherals, such as
                printers."

Except as modified herein, the provisions of the Main Agreement shall remain in
full force and effect.

IN WITNESS WHEREOF, the parties have caused this Addendum to be executed by
their duly authorized representative.

    The notice shall set forth the name, business address and telephone number

7.  Progress reports. Unless otherwise provided in the applicable Specific
    Agreements, the PROGRAM MANAGER of one party shall provide to the PROGRAM
    MANAGER of the other party monthly written progress reports for such
    Specific Agreements specifying the current work progress level and

    court of competent jurisdiction to be contrary to law, the remaining
    provisions of the contract document will remain in full force and effect and
    shall be interpreted, to the extent possible, to achieve the purpose of this
    Alliance Agreement and any affected Specific Agreements as originally
    expressed without the invalid, illegal or unenforceable provision.
