                                 LEASE AGREEMENT
                                 ---------------


    Landlord hereby leases the Leased Premises to Tenant for the duration of the
Lease Term. The leasing of the Leased Premises to Tenant will be upon the terms
and conditions set forth in this Lease.

    SECTION 1. BASE RENT. For each month of the Lease Term, Tenant will pay Base
Rent in an amount equal to the monthly installment set forth in the Lease
Summary, which Lease Summary is attached hereto and incorporated herein by this
reference.

    SECTION 2. OPERATING EXPENSE PAYMENT. Tenant will pay its Proportionate
Share of all Operating Expenses incurred by Landlord during the Lease Term in
connection with the operation, management, maintenance and repair of the Land
and the Building. Illustrative examples of those expenses which are included
within the definition of "Operating Expenses" are set forth in Exhibit B.
Tenant's Proportionate Share of such Operating Expenses will be paid by Tenant
in advance based upon Landlord's estimate of the actual Operating Expenses which
will be incurred during each calendar year during the Lease Term. The Estimated
Operating Expense Payment for the first such calendar year is set forth in the
Lease Summary. The Estimated Operating Expense Payment for each calendar year
thereafter will be adjusted based upon Landlord's estimate of its Operating
Expenses for such calendar year. Landlord will use its best efforts to notify
Tenant by December 1 of each year during the Lease Term of any adjustment in the
monthly Estimated Operating Expense Payment for the upcoming calendar year.

    As soon as reasonably practicable after the end of each calendar year,
Landlord will deliver to Tenant a written statement showing its actual Operating
Expenses for such calendar year and Tenant's actual Proportionate Share thereof.
If the sum of the Estimated Operating Expense Payments paid by Tenant during
such calendar year exceeds Tenant's Proportionate Share of the actual Operating
Expenses incurred during such year, then Landlord will apply the excess toward
the next succeeding monthly Estimated Operating Expense Payment(s) due from
Tenant. If the sum of the Estimated Operating Expense Payments paid by Tenant
during such calendar year is less than Tenant's Proportionate Share of the
actual Operating Expenses incurred during such year, then Tenant will pay the
deficiency to Landlord within ten business days after Tenant's receipt of
Landlord's written demand for the payment thereof.

   SECTION 3. MANNER AND TIMING OF RENT PAYMENTS. The first monthly installment
of Base Rent and Estimated Operating Expense Payments will be paid by Tenant on
or before the Commencement Date. Thereafter, monthly installments of Base Rent
and Estimated Operating Expense Payments will be due and payable in advance on
or before the first day of each calendar month during the Lease Term. Each such
installment will be paid to Landlord at its address set forth in the Lease
Summary (or such other address as Landlord may designate from time to time). If
the Lease Term commences on a day other than the first day of the month or
terminates on a day other than the last day of the month, then the installments
of Base Rent and Estimated Operating Expense Payments for such month(s) will be
adjusted accordingly. If any installment of Base Rent or any Estimated Operating
Expense Payment is not received by Landlord within five days after its due date,
then a late payment charge of 5% of such past due amount will be immediately due
and payable from Tenant. All installments of Base Rent and Estimated Operating
Expense Payments will be paid by Tenant without demand and without any rights of
reduction, counterclaim or offset. Tenant hereby agrees to pay as additional
rent any sales, use or other tax (other than income taxes) now or hereafter
imposed by any governmental authority upon the rent and other sums payable by
Tenant hereunder.

    SECTION 4. UTILITIES. Tenant will pay all costs associated with the
provision of all utility services to the Leased Premises, including, without
limitation, telephone, gas, electricity, water and sewer service. To the extent
possible, all utility services will be separately metered to the Leased Premises
and placed in Tenant's name. If it is not possible to place a utility service on
a separate meter in Tenant's name, then all costs associated with the provision
of such utility service to the Leased Premises will be billed directly by
Landlord to Tenant and will be paid by Tenant within 15 days after its receipt
of such billing. Landlord will not be liable to Tenant, nor will Tenant be
relieved of any obligation hereunder if any utility service to the Leased
Premises is interrupted for any reason beyond Landlord's control.

    SECTION 5. MAINTENANCE AND REPAIR. Tenant will at its sole expense maintain
the Leased Premises in a first-class condition and order of repair. Tenant's
maintenance obligation will extend to and include the repair and replacement, if
necessary, of all structural and non-structural elements and mechanical systems
located wholly within and solely serving the Leased Premises. Any repairs or
replacements made to the Leased Premises by Tenant pursuant to this Section 5
will be made in a workmanlike manner with materials at least equal in quality
and grade to those originally contained within the Leased Premises. Tenant will
also contract for its own janitorial and trash removal services and will
promptly pay all costs associated with such services.




                                       1

    Landlord will maintain, repair and, if necessary, replace, the roof, roof
membrane and exterior walls of the Building (including exterior glass), all
structural and mechanical systems located within the Building (including
plumbing, heating, HVAC and electrical systems) unless the maintenance and
repair of the same are Tenant's responsibility under the immediately preceding
paragraph, and all common areas serving the Building (including, without
limitation, the parking lot, driveways and loading dock areas) in a first-class
condition and order of repair. Except as otherwise expressly provided in this
Section 5 and Section 9, Landlord will not at any time during the Lease Term be
required to make any improvements, repairs, replacements or alterations to the
Leased Premises.

    SECTION 6. USE OF PREMISES. Tenant will use the Leased Premises solely for
the Permitted Use. Tenant will not cause or permit any waste or damage to the
Leased Premises, the Building or the Land and will not occupy or use the Leased
Premises for any business or purpose which is unlawful, hazardous, unsanitary,
noxious or offensive or which unreasonably interferes with the business
operations of other tenants in the Building. If the nature of Tenant's use or
occupancy of the Leased Premises (other than the Permitted Use defined in the
Lease Summary) causes any increase in Landlord's insurance premiums over and
above those chargeable for the least hazardous type of occupancy legally
permitted in the Leased Premises, then Tenant will pay the resulting increase
within ten days after its receipt of a statement from Landlord setting forth the
amount thereof. Tenant will comply with the Rules and Regulations for the
SouthPark which are set forth in Exhibit C (and any reasonable modifications
thereto which are consistent with the provisions of this Lease).

    SECTION 7. GOVERNMENTAL REQUIREMENTS. Tenant will at its sole expense comply
with all laws and other governmental requirements which are now or hereafter in
force pertaining to the Leased Premises and Tenant's occupancy and use thereof,
including, without limitation, the Americans with Disabilities Act, the
Comprehensive Environmental Response, Compensation and Liability Act the Clean
Air Act, the Hazardous Materials Transportation Act, the Resource Conservation
and Recovery Act and the Water Pollution Control Act. Landlord hereby represents
and warrants that the Building will, as of the date on which Tenant first
occupies any portion of the Building, be in full compliance with all applicable
laws and other governmental requirements, including, without limitation, the
laws referred to in the immediately preceding sentence.

    SECTION 8. SIGNS. Tenant will not place any sign or other advertising
material on the exterior or interior of the Leased Premises or the Building,
without the prior written consent of Landlord.

    SECTION 9. LEASEHOLD IMPROVEMENTS. Attached to this Lease as Exhibit D are
either: (a) the preliminary specifications for the improvements to be made to
the Initial Leased Premises ("Improvements"); or (b) a tenant improvement
allowance for such Improvements. To the extent Exhibit D simply sets forth a
tenant improvement allowance for such Improvements, Landlord and Tenant agree
that, promptly following the parties' execution of this Lease, they will meet to
develop approved preliminary specifications for the Improvements. Once Landlord
and Tenant have approved preliminary specifications (either by the initial
attachment of the same hereto as Exhibit D or as a product of their meeting
promptly following the execution of this Lease), Landlord will proceed with the
preparation of the final architectural and engineering drawings, plans and
specifications for the Improvements. Once those drawings, plans and
specifications are completed, Landlord will deliver a full set thereof to Tenant
for its review and approval. The approved final drawings, plans and
specifications ("Final Plans") are incorporated herein by this reference.

    If Exhibit D simply sets forth a tenant improvement allowance number and if
the cost of constructing the Improvements in accordance with the approved Final
Plans (as determined by Landlord's general contractor) exceeds the amount of
such tenant improvement allowance, and if, following Tenant's receipt of written
notice from Landlord of the amount of such excess costs and Tenant nonetheless
authorizes Landlord to proceed to incur such excess costs, then, in such event,
Tenant will pay any such excess costs upon completion of said improvements and
within ten days after Landlord's written demand for the payment thereof. If,
following the approval of the Final Plans, Tenant expresses a desire to make any
revisions thereto, Tenant will so notify Landlord and Landlord will then ask its
general contractor to prepare a cost estimate for the making of such changes.
Landlord will promptly notify Tenant of any increased costs or savings resulting
from such changes and Tenant will have the right to require Landlord to cause
such a change to be made to the Final Plans; provided, however, that such
changes will not unreasonably affect the structural integrity or value of the
Building. If the aggregate of all such changes results in a net increase in the
cost of the construction of the Improvements, (net of any savings), then Tenant
will pay such net increase to Landlord within 10 business days after Landlord's
written demand for the payment thereof.

    Landlord will cause the Improvements to be constructed in accordance with
the Final Plans. Landlord will use its best efforts to substantially complete
construction of the Improvements on or before the targeted Commencement Date set
forth in the Lease Summary, subject to delays caused by the occurrence of events
beyond its reasonable control, including, without limitation, labor troubles,
inability to procure materials, restrictive governmental laws and
pronouncements, acts of God, unseasonable weather, Tenant's failure to timely
respond to any matter submitted for its review and Tenant's requested change
orders ("Delay Events"). The establishment of the substantial completion date
referred in the immediately preceding sentence is predicated upon the various
Milestone Dates referred to in Exhibit D 




                                        2
<PAGE>   5


being met in a timely manner with respect to the preparation, submission and
approval of all preliminary specifications and Final Plans. Tenant agrees that
it will review and either approve or specify its objections to any documents or
drawings submitted to it for its review and approval hereunder within five
business days after its receipt of the same.

  If Landlord's inability to substantially complete the Improvements on or
before the targeted Commencement Date set forth in the Lease Summary is
attributable to any Delay Event (other than those tenant-caused delays referred
to in the immediately succeeding sentence), then the Commencement Date will be
deferred by the number of days of the delay in substantially completing the
Improvements which is caused by the occurrence of any such Delay Events. If
Landlord is unable to substantially complete construction of improvements on or
before the date which is 120 days after both parties' execution of the Lease,
for any reason other than the occurrence of a Delay Event, then Tenant will
thereafter have the right for 30 days after the expiration of such 120 day
period to terminate this Lease by delivery of written notice to such effect to
Landlord. Notwithstanding anything to the contrary contained herein, if
Landlord's inability to substantially complete the improvements on or before the
targeted Commencement Date set forth in the Lease Summary is attributable to
Tenant-caused delays (including, without limitation, Tenant's failure to timely
respond to any manner submitted for its review, delays caused by Tenant's
requested change orders, as verified by Landlord's general contractor, or
Tenant's failure to meet the Milestone Dates referred to in the Lease Summary),
then the Commencement Date will remain as set forth in Exhibit F,
notwithstanding the fact that the Improvements are not yet substantially
completed, and Tenant will, from and after the Commencement Date, have an
obligation to pay Base Rent, Estimated Operating Expense Payments and perform
all of its other obligations and duties hereunder. For the purposes of this
Lease, the Improvements will be deemed substantially completed on the earlier of
the date on which Tenant occupies the Leased Premises or the date on which a
temporary or permanent certificate of occupancy for the Improvements is issued
by the appropriate governmental authority. Landlord will be responsible for
securing a certificate of occupancy for the improvements from the appropriate
governmental authority.

   SECTION 10. ALTERATIONS. Except for "Minor Alterations" (as that term is
hereafter defined). Tenant may not at any time prior to or during the Lease Term
make any alterations, additions or improvements to the Leased Premises without
the prior written consent of Landlord. For the purposes of this Section 10,
"Minor Alterations" will mean any alteration, addition or improvement to the
Leased Premises which costs less than $10,000, and which does not alter the
exterior aesthetics pr structural integrity of the Building. All improvements,
alterations and additions made at one time in connection with any one job will
be aggregated for the purposes of determining whether the $10,000 limit has been
exceeded. Any alterations, addition or improvement made to the Leased Premises
in accordance with this Section 10 will at all times remain the property of
Landlord. If Landlord consents to any proposed alteration, addition or
improvement, the same shall be made at Tenant's sole expense.

    SECTION 11. MECHANICS LIENS. Tenant will indemnify and hold Landlord
harmless from any liability or expense associated with its construction of any
alteration, addition or improvement to the Leased Premises, unless Landlord is
itself constructing any such alteration, addition or improvement. Tenant will
immediately discharge any mechanics lien filed against the Leased Premises, the
Building or the Land in connection with any work performed by or at the request
of Tenant.

    SECTION 12. ASSIGNMENT AND SUBLETTING. Tenant will not assign this Lease or
sublet all or any part of the Leased Premises without the prior written consent
of Landlord. Unless otherwise agreed to by Landlord, Landlord's consent to any
such assignment or sublease will not relieve Tenant from its obligations under
this Lease. Notwithstanding anything to the contrary contained herein, Tenant
may, without having to obtain the prior written consent of Landlord, assign this
Lease or sublet all or any part of the Leased Premises to any parent, affiliate
or subsidiary of Tenant, so long as Tenant remains fully liable for the
performance of all of its obligations hereunder notwithstanding such assignment
or sublease. If Landlord consents to any sublease by Tenant, then Tenant will be
permitted to retain all rent payable in connection with such sublease.

    SECTION 13. SUBORDINATION. Tenant's rights and interests under this Lease
will be subordinate to all mortgages and other encumbrances now or hereafter
affecting any portion of the Building or the Land. In the event of the
foreclosure of any mortgage or other encumbrance, Tenant will, upon request of
any person succeeding to the interest of Landlord, attorn to and automatically
become the tenant of such successor-in-interest without change in the terms or
conditions of this Lease; provided, however, that such successor-in-interest
will not be liable for any act or omission of any prior landlord or subject to
any offsets or defenses which Tenant may have against any such prior landlord.
The obligations of Tenant under this Section 13 will be expressly conditioned
upon its receipt of an acceptable subordination, non-disturbance and attornment
agreement from any mortgagee of Landlord, which subordination, non-disturbance
and attornment agreement will expressly provide that Tenant will be entitled to
the undisturbed possession of the Leased Premises, so long as it is in full
compliance with all of its obligations under this Lease. Within ten business
days after its receipt of Landlord's request therefor, Tenant will execute and
deliver to Landlord a certificate prepared by Landlord confirming such
subordination and attornment and setting forth the current status and facts
related to this Lease and Tenant's occupancy of the Leased Premises.

    SECTION 14. LIMITATION OF LANDLORD'S PERSONAL LIABILITY. Tenant will look
solely to Landlord's interest in the Leased Premises, the Building and the Land
for the recovery of any judgment against Landlord; it being the express intent
of the parties hereto that neither Landlord, nor any of its shareholders,
directors, officers or employees will ever be personally liable for any such
judgment.

    SECTION 15. INDEMNIFICATION AND INSURANCE. Landlord will not be liable for
and Tenant will indemnify and hold Landlord harmless from any liability or
expense associated with any damage or injury to any person or property
(including any person or property of Tenant or any one claiming under Tenant)
which arises directly or indirectly in connection with the Tenant's use or
occupancy of the Leased Premises; provided, however, that Tenant will not be
obligated to indemnify Landlord as to any liability or expense occasioned by the
fault or negligence of Landlord.

    All property stored or placed by Tenant in or about the Leased Premises will
be so stored or placed at the sole risk of Tenant. Tenant will at its sole
expense maintain in full force and effect at all times during the Lease Term:
(a) comprehensive public liability insurance for personal injury and property
damage with liability limits of not less than $5,000,000 for injury to one
person, $10,000,000 for injury from one occurrence and $2,000,000 for property
damage; and (b) extended coverage insurance on all property stored or placed by
Tenant in or about the Leased Premises in an amount equal to the full
replacement value thereof. Each insurance policy required to be maintained by
Tenant hereunder will name Landlord and Landlord's mortgagee, if any, as
additional insureds and will specifically provide that such insurance policy
cannot be terminated without giving at least 30 days prior written notice to
Landlord and Landlord's mortgagee, if any.

    SECTION 16. HAZARDOUS SUBSTANCES. Tenant will not use, store or dispose of
any Hazardous Substance (as that term is hereafter defined on or about the
Leased Premises, except for immaterial amounts that are exempt from or do not
give rise to any violation of applicable law. Tenant agrees to indemnify and
hold Landlord harmless from any liability or expense (Including, without
limitation, the fees of Landlord's attorneys and consultants and the cost of any
required remediation or clean-up) incurred by or claimed against Landlord as a
result of Tenant's breach of the covenant contained in this paragraph. The
foregoing covenant will survive the termination of this Lease for 12 months
after such termination. For the purposes of this Section 17, the term "Hazardous
Substance" means any "hazardous substance", "toxic substance" (as those terms
are defined in the Comprehensive Environmental Response, Compensation and
Liability Act), "hazardous waste" (as that term is defined in the Resource
Conservation Recovery Act), polychlorinated biphenyls, asbestos, radioactive
material or any other pollutant, contaminant or hazardous, dangerous or toxic
material or substance which is regulated by any federal, state or local law,
regulation, ordinance or requirement. Landlord represents and warrants that, as
of the Commencement Date, there will not be any Hazardous Substances in or about
the Building or the Leased Premises, except for immaterial amounts that are
exempt from or do not give rise to any violation of applicable law. Landlord
agrees to indemnify and hold Tenant harmless from any liability or expense
(including, without limitation, fees of Tenant's attorneys and consultants and
the cost of any required remediation or clean-up) incurred by or claimed against
Tenant as a result of Landlord's breach of the representation and warranty
contained in this paragraph.

    SECTION 17. SURRENDER OF PREMISES. Upon the termination of Tenant's right of
possession under this Lease, Tenant will immediately surrender possession of the
Leased Premises to Landlord in good repair and "broom clean" condition,
reasonable wear and tear and fire and casualty excepted. Tenant will at the same
time remove all of its movable trade fixtures from the Leased Premises. Tenant
will promptly repair any damage caused to the Leased Premises by the removal of
any of such movable trade fixtures.

    SECTION 18. CASUALTY. If the Leased Premises are damaged by fire or other
casualty, Landlord shall promptly give written notice to Tenant whether the
Leased Premises can reasonably be repaired within 180 days after the date of the
occurrence of such fire or other casualty. If Landlord notifies Tenant that it
does not believe that the Leased Premises can reasonably be repaired within such
180-day period, then both Landlord and Tenant will have the option of
terminating this Lease by giving written notice thereof to the other at any time
within 30 days after the date of Tenant's receipt of the aforementioned notice
from Landlord. If Landlord determines that the Leased Premises can reasonably be
repaired within such 180-day period or if neither party elects to terminate this
Lease despite the fact that Landlord has determined that the Leased Premises
cannot be reasonably repaired within such 180-day period, then Landlord will
proceed to repair the Leased Premises at its sole expense; provided, however,
that Landlord will in no event be required to repair any improvements previously
made to or any fixtures previously installed in the Leased Premises by Tenant
(other than the improvements initially constructed to the Leased Premises by
Landlord pursuant to Section 9 and Exhibit D). If the Leased Premises are
rendered untenantable in whole or in part as a result of a fire or other
casualty, then all rent accruing after the occurrence of any such fire or other
casualty and prior to the completion of the repair of the Leased Premises will
be equitably and proportionately abated to reflect the untenantable portion of
the Leased Premises. Landlord will not be liable to Tenant for any inconvenience
or interruption to Tenant's business occasioned by such fire or other casualty
or the concomitant repair of the Leased Premises.



                                       4
<PAGE>   7



    SECTION 19. CONDEMNATION. If all or any substantial portion of the Leased
Premises or the Building is taken by or under threat of condemnation so as to
render the Leased Premises wholly untenantable, then this Lease will
automatically terminate as of the date of the vesting of title to such property
in the condemning authority. If such taking does not render the Leased Premises
wholly untenantable, then this Lease will not terminate but will continue in
full force and effect in accordance with its terms, except that the Base Rent
and Tenant's Proportionate Share will be adjusted to fairly reflect the portion
of the Leased Premises or the Building which was so taken. Landlord will not be
liable to Tenant for any inconvenience or interruption to Tenant's business
occasioned by any such taking. Landlord will be entitled to receive the entire
award made by the condemning authority for any such taking.

    SECTION 20. HOLDING OVER. Tenant will not hold over in its occupancy of the
Leased Premises after the expiration of the Lease Term, without the prior
written consent of Landlord. If Tenant holds over without the prior written
consent of Landlord, then Tenant will pay 125% of the Base Rent and Estimated
Operating Expense Payment then in effect for each month during the entire
holdover term. Any holding over with the consent of Landlord will constitute
this Lease as a lease from month-to-month.

    SECTION 21. DEFAULT. If Tenant fails to pay any installment of Base Rent,
any Estimated Operating Expense Payment or any other sum payable by it hereunder
on or before the date when due, or if Tenant defaults in the performance of any
of its other obligations under this Lease and such default continues for 30 days
after written notice thereof is given to Tenant (or if such default is not
capable of being cured within 30 days, then only if Tenant fails to commence a
cure of such default within such 30 day period and at all times thereafter
proceed with due diligence to cure the same), then, in addition to any other
legal rights and remedies available to Landlord at law or in equity, Landlord
may: (a) terminate this Lease and declare all Base Rent, Estimated Operating
Expense Payments and other sums payable over the remainder of the Lease Term to
be immediately due and payable; or (b) re-enter and attempt to relet the Leased
Premises without terminating this Lease, in which event Tenant will remain
obligated to pay to Landlord any deficiency between all sums payable by Tenant
pursuant to this Lease and any sums collected by Landlord from any reletting of
the Leased Premises (net of any sums paid by Landlord in connection with such
reletting, including, without limitation, leasing commissions, attorneys' fees
and costs of improvements to the Leased Premises). Notwithstanding anything to
the contrary contained in this Section , Landlord will not have the right to
pursue any of the aforementioned legal rights and remedies in the event of a
monetary default by Tenant hereunder unless, on not more than two occasions in
any 12 month period, Landlord has first delivered written notice of non-payment
of any monetary sum to Tenant and Tenant has failed to cure such non-payment
within ten days after its receipt of such written notice.

    SECTION 22. PREVAILING PARTY'S FEES. If any legal action is commenced by
either Landlord or Tenant, to enforce its rights hereunder, then all attorneys'
fees and other expenses incurred by the prevailing party in such action shall be
promptly paid by the non-prevailing party.

    SECTION 23. SUCCESSORS AND ASSIGNS. This Lease shall be binding upon and
inure to the benefit of the successors and assigns of Landlord and the
successors and permitted assigns of Tenant.

    SECTION 24. NO WAIVER. No waiver of any covenant or condition of this Lease
by either party will be deemed to constitute a future waiver of the same or any
other covenant or condition of this Lease. In order to be effective, any such
waiver must be in writing and must be delivered to the other party to this
Lease.

    SECTION 25. BROKERAGE COMMISSIONS. Each of Landlord and Tenant hereby
represents and warrants that it has not dealt or consulted with any real estate
broker or agent in connection with this Lease other than those real estate
brokers and agents specifically identified in the Agency Disclosure Statement
attached hereto as Exhibit E. Each of Landlord and Tenant agrees to indemnify
and hold the other harmless from and against any liability or expense occasioned
by a breach of the foregoing representation.

    SECTION 26. REASONABLENESS OF CONSENT. Landlord will not unreasonably
withhold any consent or approval which is required to be given by it pursuant to
the terms of this Lease.

    SECTION 27. AMENDMENT. This Lease may not be amended except by a written
instrument signed by both Landlord and Tenant.

    SECTION 28. GOVERNING LAW. This Lease will be governed by and construed in
accordance with the laws of the State of Ohio.

    SECTION 29. NOTICES. All notices required or permitted under this Lease must
be in writing and must be delivered to Landlord and Tenant at their addresses
set forth in the Lease Summary (or such other address as may hereafter be



                                       5

designated by such party). Any such notice must be personally delivered or sent
by either registered or certified mail or overnight courier.


    SECTION 30. SPECIAL TERMS. Exhibit F sets forth those special provisions, if
any, which supplement the provisions of this Lease.

                 RIDER TO LEASE BETWEEN DECISION ONE CORPORATION
                  AND 3423 SOUTHPARK PLACE DEVELOPMENT COMPANY

                              DATED APRIL ___, 1997

For the Demised Premises located at 3423 SouthPark Place, Grove City, Ohio.

The provisions of this Rider are incorporated into, and in the event of any
contradictions shall supersede, the terms of the Lease referenced in the title
of this Rider and any other amendments or modifications thereof.

1.   LANDLORD'S OBLIGATIONS. Landlord at its sole expense shall be responsible
     for all costs and expenses associated with the maintenance, repair and
     replacement of the roof, foundations, exterior walls, all structural parts
     of the Building, and all mechanical, electrical and structural systems of
     the Building, including HVAC and telecommunications and sprinkler systems,
     the source of which lie outside the Leased Premises or which do not serve
     solely the Leased Premises.

2.   INSURANCE: WAIVER OF SUBROGATION. Landlord shall maintain fire and full
     extended coverage insurance, including vandalism and malicious mischief,
     for full replacement cost of Landlord's property; with reputable insurance
     companies. Each party hereby waive subrogation against the other, its
     officers and employees for any damage covered by insurance required
     pursuant to the Lease and this Rider regardless of which party caused such
     damage in whole or in part. Both parties shall cause their respective
     carriers to issue endorsements to their insurance policies to the effect
     that the carrier agrees to be bound by such waiver of subrogation.

3.   ACCESS. Access to the Leased Premises, including elevator service if
     applicable, shall be provided to Tenant and its invitees on a seven
     day-a-week, 24 hour-a-day basis.

4.   LIEN ON PERSONAL PROPERTY. Regardless of whether Tenant is in default under
     the Lease, Landlord waives all right of distraint, attachment, lien, levy,
     execution against and security interest, statutory or otherwise, on and in
     Tenant's personal property and trade fixtures and such property located in
     the Leased Premises for which Tenant acts as bailor. Tenant reserves the
     right to remove any such property from the Leased Premises at any time.

5.   CERTIFICATE OF OCCUPANCY. Landlord shall obtain a certificate of occupancy,
     or such other similar permit or license as is required by the locality in
     which the Leased Premises are situated, for Tenant's occupancy of the
     Leased Premises for the uses permitted by the Lease and for such build-out
     and work undertaken by Landlord at the commencement of the Lease or at such
     other times as stated in the Lease (not to include alterations made by
     Tenant thereafter).

6.   CONSENT AND APPROVALS. Whenever any action of any party contemplated by the
     Lease requires the consent or approval of the other party, each party
     agrees that such consent shall not be unreasonably withheld or delayed. If
     the Lease contains any provision with respect to non-waiver of default,
     self-help, or the right to counsel fees in the event of enforcement of a
     party's rights under the Lease, then in each instance the provision shall
     be interpreted as though both parties are favored thereby.

7.   SUBORDINATION. If, in connection with a financial arrangement related to
     the Building or any part thereof of which the Leased Premises are a part, a
     bank, insurance company or other lender requests a modification to the
     Leases, Tenant shall only be required to consent to or execute the same if
     the modifications do not materially increase any responsibility, monetary
     of otherwise, or decrease any rights of Tenant under the Lease.

8.   NO SURCHARGE FOR PERMITTED USES. Landlord acknowledges and agrees that with
     respect to any insurance policies maintained by Landlord now or during the
     term of the Lease, Tenant's use of the Leased Premises in the regular
     course of business as permitted by the Lease shall not be the basis for
     imposing on Tenant any surcharge or other obligation by reason of increase
     in premiums or surcharge on Landlord; nor shall such use be the basis for
     any additional charges for utilities or otherwise, other than charges
     expressly set forth in the Lease. Tenant's obligation of performance in
     order to comply with the laws not currently enacted shall arise only from a
     change of law relating specifically to Tenant's use of the Leased Premises
     other than as general office use.

9.   LIMITATIONS OF LIABILITY. In no event shall Tenant be liable, pursuant to
     any indemnification provision in the Lease or otherwise, for an
     consequential or indirect damage or loss.

                       FIRST AMENDMENT TO LEASE AGREEMENT
                       ----------------------------------

                                August __, 1997

This First Amendment to Lease Agreement ("Amendment") is entered into as of the
date set forth above by 3423 SouthPark Place Development Company ("Landlord")
and DecisionOne Corp. ("Tenant").

                                   BACKGROUND
                                   ----------

Effective as of April 10, 1997, Landlord and Tenant entered into a Lease
Agreement ("Original Lease") pursuant to which Tenant agreed to lease 58,597
square feet of rentable space contained in the building located at 3423
SouthPark Place in Grove City, Ohio. The Original Lease further contemplated
that Tenant was obligated to lease an additional 57,976 square feet of space
("Expansion Space") no later than nine months after the commencement date of the
initial term of the Original Lease. Tenant has now expressed a desire (1) to
accelerate the commencement date of its leasing of the Expansion Space, and (2)
to lease an additional 57,976 square feet of space located adjacent to the
Expansion Space ("New Space"). The location of the Expansion and New Spaces are
shown on the floor plan attached hereto as Exhibit A.

The parties now desire to enter into this Amendment to reflect the terms and
conditions upon which Tenant's leasing of the Expansion and New Spaces will be
effected. All capitalized terms which are used, but not defined herein, will
have the meanings attributed to such terms in the Original Lease.

                                   AGREEMENT
                                   ---------

Landlord and Tenant herby agree as follows:

     Section 1. ACCELERATION OF LEASING OF EXPANSION SPACE. The commencement
date of Tenant's leasing of the Expansion Space (that is, bays 20-23,
consisting of 57,976 square feet of rentable space) will be September 15, 1997
("Expansion Space Commencement Date"). The term of Tenant's leasing of the
Expansion Space will otherwise be co-terminus with its leasing of the initial
Leased Premises under the Original Lease. Tenant will pay Base Rent to Landlord
for the Expansion Space of $12,320 per month (the equivalent of $2.55 per
rentable square foot per year). In addition to its obligation to pay such Base
Rent, Tenant will, at all times from and after the Expansion Space Commencement
Date, be required to comply with all of the provisions of the Original Lease
for the remainder of the Lease Term (including, without limitation, the
obligation to pay Estimated Operating Expense Payments in the same per rentable
square foot amount then being paid by Tenant with respect to the initial Leased
Premises).

     Section 2. LEASING OF NEW SPACE. Effective as of March 1, 1998 ("New Space
Commencement Date"), Tenant will lease the New Space from Landlord (that is,
bays 16-19, consisting of 57,976 square feet of rentable space). The term of
Tenant's leasing of the New Space will otherwise be co-terminus with its
leasing of the initial Leased Premises under the Original Lease. Tenant will
pay Base Rent to Landlord for the New Space of $12,803 per






                                       1
<PAGE>   13
month (the equivalent of $2.65 per rentable square foot per year). In addition
to its obligation to pay such Base Rent, Tenant will, at all times from and
after the New Space Commencement Date, be required to comply with all of the
provisions of the Original Lease for the remainder of the Lease Term
(including, without limitation, the obligation to pay Estimated Operating
Expense Payments in the same per rentable square foot amount then being paid by
Tenant with respect to the initial Lease Premises).

     Section 3. TENANT IMPROVEMENTS. Landlord will provide a tenant improvement
allowance of $125,000 to cover all hard and soft costs associated with the
construction of improvements to the Expansion and New Spaces. The preliminary
and final plans for any such improvements will be prepared, submitted and
approved in accordance with the procedures set forth in Section 9 of the
Original Lease. If the cost of the construction of any such improvements
ultimately approved by Landlord and Tenant exceeds the amount of the
aforementioned tenant improvement allowance, then such excess costs will be
paid by Tenant in accordance with the provisions of Section 9 of the Original
Lease. If the cost of the construction of the improvements ultimately approved
by the Landlord and Tenant is less than the amount of the aforementioned tenant
improvement allowance, then, at the election of Tenant, such diminished costs
will either be (a) paid in cash to Tenant within 30 days after the completion of
construction of the improvements, (b) credited against the next rent payments
due from Tenant hereunder or (c) reserved for the construction of future
improvements to the New and Expansion Spaces. Landlord will no longer be
obligated under the terms of the Original Lease to construct a demising wall in
Bay 24.

     Section 4. EARLY OCCUPANCY. Tenant will have access to the New and
Expansion Spaces as of the date hereof, so as to permit Tenant to begin
installing its fixtures and otherwise readying such space for its use and
occupancy. Tenant's obligation to pay Base Rent with respect to the New and
Expansion Spaces will not commence until the commencement dates set forth in
Sections 1 and 2, respectively. Tenant will, however, from and after the date on
which it assumes early occupancy of the New Expansion Spaces under this Section
4, be obligated to make Operating Expense Payments to Landlord with respect to
the New and Expansion Spaces. The amount of such Operating Expense Payments will
be calculated on the basis of a $.32 per rentable square foot per year formula
and will be paid by Tenant in advance on or before the first day of each
calendar month throughout the period of its early occupancy of the New and
Expansion Spaces.

     Section 5. RENEWAL OPTIONS. The renewal options granted to Tenant pursuant
to paragraph 3 of Exhibit F to the Original Lease will be fully applicable to
each of the New and Expansion Spaces. In order to be effective, Tenant's
exercise of any such renewal option must apply to all of the space being leased
by it in the Building (that is, the initial Leased Premises, the Expansion Space
and the New Space). In determining the Base Rent payable by Tenant during any
exercised renewal term, the Base Rent payable by it with respect to each of the
Initial Leased Premises, the Expansion Space and the New Space will be
separately calculated using the formula set forth in paragraph 3 of Exhibit F to
the Original Lease.

     Section 6. MISCELLANEOUS. Except as otherwise expressly provided herein,
the Original Lease will remain in full force and effect.
