neighboring properties, that was caused or materially contributed to by Lessee,
or pertaining to or involving any Hazardous Materials brought onto the demised

tear.

<PAGE>   3

              Lessor agrees to obtain a service contract on the HVAC system with
a firm which is reasonably satisfactory to Lessor. Such contract shall provide
for at least quarterly inspections, and with written reports to Lessor and

              Lessor shall be responsible for all exterior improvements and

and the care and maintenance of the parking areas and grounds, except as
provided for elsewhere in this Lease. Lessee shall give reasonable advance
notice to Lessor of required repairs to the roof, structure, parking areas, or
grounds.

              Lessee further covenants and agrees that at the end of the term,
it will deliver up the demised premises broom-clean, free of debris and in as
good order and condition as they are at commencement hereof or may be put to
thereafter, reasonable use and reasonable and ordinary wear and tear excepted.
All of the obligations of Lessee shall include the repair of any damage
occasioned by the installation, maintenance or removal of Lessee's trade
fixtures, furnishings, equipment, as well as the removal of any materials that
are left by Lessee.

              Lessee shall be responsible for all interior janitorial service
respecting the demised premises.

              Lessee covenants and agrees that it will neither do nor permit to
be done any act or thing on the demised premises or elsewhere which will
invalidate any insurance on the demised premises or increase the premiums for
insurance thereon if said invalidation or increase is the result of Lessee's
change of use of the demised premises.

              Lessee may, at its own cost and expense, from time to time during
the term of this Lease, make such alterations, additions and changes, structural
and otherwise, in and to the demised premises as it finds necessary or
convenient for its purposes; provided, however: (i) that Lessee shall indemnify
and save harmless Lessor from all expenses, liens, claims of damages to any
person or property arising out of or resulting from the undertaking or making of
such alterations, additions and/or changes; (ii) that such alterations,
additions and/or changes shall increase the value of the demised premises, and
in no manner adversely affect the use thereof, or the rights of Lessor, such
adverse affect to be determined in Lessor's sole opinion; an (iii) that written
consent shall be first obtained from Lessor before undertaking the same, which
consent shall not be unreasonably withheld. Such consent may, at the option of
Lessor, be either on the basis that Lessee shall restore the demised premises to
substantially their original condition at the termination of this Lease, or that
no restoration will be required. All trade fixtures, trade apparatus, trade
machinery and trade equipment placed on the demised premises at the expense of
Lessee shall remain the property of Lessee, and may be removed by Lessee at any
time prior to and upon termination of this Lease. Copies of all plans and
specifications, including as-built plans, shall be provided to Lessor by Lessee.

V. REAL ESTATE TAXES AND ASSESSMENTS. Lessor shall be responsible for the
payment of all real estate taxes and assessments regarding the Demised Premises.

VI. FIRE AND CASUALTY.

         A. In the event of partial damage to or destruction of the Premises
during the term hereof, which does not render the Premises untenantable by
Lessee, Lessor at its sole cost and expense will, within a reasonable time,
restore, repair, replace, rebuild or alter the same to their condition
immediately prior to such damage or destruction or as near thereto as is
reasonably possible. Lessor will be entitled to apply the proceeds of Lessor's
insurance coverage to the cost of such restoration and repair.

         B. If such damage or destruction is total or renders the Premises
untenantable by Lessee and if it does not appear to be feasible, in Lessor's
determination for Lessor to complete such restoration, repair and replacement
work within "a reasonable period" after the date of such damage or destruction,
then Lessor will have the right to terminate this Lease by delivery of written
notice thereof to Lessee within thirty (30) days after the date of such damage
or destruction.

              C. If Lessor plans to restore, repair, and replace the Premises to
their condition immediately prior to such damage or destruction, or as near
thereto as is reasonably possible, within the reasonable period provided for
above, Lessor will deliver its statement to that effect to Lessee within thirty
(30) days after the date of such damage or destruction. Upon receipt of said
statement, in the event that Lessee determines that, in its opinion, the period
for restoration, repair and replacement work is not reasonable, Lessee has the
right to terminate this Lease by delivery of written notice thereof to Lessor
within fifteen (15) days of receipt by Lessee of said statement from Lessor.

         D. Lessor's obligation to restore the Premises is limited in every
instance to the insurance proceeds actually paid to it for such purpose as a
result of damage or casualty to the Premises. However, Lessor shall restore the
Premises to a condition similar to that condition in which the Premises were in
prior to the damage or destruction.

         E. During any time that any portion of the Premises are untenantable,
in whole or in part, the rent provided for herein will abate, in proportion to
the extent the Premises have become untenantable, from the date the Premises
become untenantable. However, if such damage resulted from or was contributed to
by the act, fault or neglect of Lessee, Lessee's employees, invitees or agents,
there will be no abatement of rent.

         F. In case of the initial destruction of the Building by fire or
otherwise, or so much thereof that Lessor desires to raze the Building (whether
or not the Premises be affected), the rent will be paid up to the time of
destruction, and then and from thenceforth this Lease will terminate.

VII. INSURANCE.

<PAGE>   5

         A. Lessor shall insure the building and keep it insured during the term
against loss or damage by fire or other casualty normally covered by extended
coverage endorsements.

         B. Lessee shall at all times maintain at its expense the following
insurance in respect to the demised premises:

                  1. General public liability insurance against claims for
bodily injury, death or property damage occurring on, in or about the demised
premises and the adjoining streets, sidewalks and passageways, with limits of

or death to any one person, not less than Two Million Dollars ($2,000,000.00)
with respect to any one accident, and not less than One Million Dollars
($1,000,000.00) with respect to property damage.

                  2. Workers' compensation insurance or comparable insurance
under applicable laws covering all persons employed in connection with any work
done on or about the premises for which claims for death or bodily injury could
be asserted against Lessor, Lessee or the premises.

                  3. Such other insurance upon or in respect of the demised
premises or the operation thereof, in such amounts and against such other
insurance hazards as lessor may from time to time reasonably require.

         C. All insurance to be provided by Lessee pursuant to this Lease shall
be written by companies acceptable to Lessor, and all such insurance shall name
as the insured parties Lessor, Lessee, and any property manager for Lessor, and
Lessor's mortgagee (as their respective interests may appear).

         D. Insurance claims by reason of damage to or destruction of any
portion of the demised premises shall be payable to Lessor and/or Lessor's
mortgagee, or an insurance trustee, if so required by Lessor and/or Lessor's
mortgagee.

         E. Every policy required by this Lease shall contain an agreement by
the insurer that it will not cancel or modify such policy, except after thirty
(30) days' prior written notice to Lessor and/or Lessor's mortgagee, and that
any loss otherwise payable thereunder shall be payable notwithstanding any act
or negligence of the insured, and notwithstanding: (i) the occupation or use of
the demised premises for purposes more hazardous than permitted by the terms of
such policy; (ii) any foreclosure or other action or proceeding taken by any
mortgagee or notice of sale relating to the premises; or (iii) any change in
title to or ownership of the demised premises.

         F. Lessee shall deliver to Lessor simultaneously with the execution and
delivery of this Lease, certificates of the insurers satisfactory to Lessor and
Lessor's mortgagee, evidencing all the insurance which is required to be
maintained by Lessee hereunder, and Lessee shall maintain such insurance
continuously throughout the term hereof. Lessee shall, as soon as practicable,
but in all events within thirty (30) days of the renewal date of any such
insurance, deliver additional certificates of the insurers satisfactory to
Lessor, evidencing the renewal of such insurance. Should Lessee fail to effect,
maintain or renew any insurance provided for in

<PAGE>   6

this section or to pay the premium therefor, or to deliver to Lessor any of such
certificates as required herein, then and in any of said events Lessor, at its
option, but without obligation so to do, may procure such insurance, and any
sums expended by it to procure such insurance shall be additional rent
hereunder, and shall be repaid by Lessee within fifteen (15) business days
following the date on which such expenditure shall be made by Lessor.

         G. Lessee agrees to carry adequate fire and extended coverage on all of
Lessee's personal property located in the demised premises, including leasehold
improvements, inventory, trade fixtures and other property installed or placed
on the demised premises by Lessee.

         H. WAIVER OF SUBROGATION. Lessor and Lessee do hereby waive all rights
of recovery and causes of action which either have or may have or which may
arise hereafter against the other, whether caused by negligence or otherwise,
for any damage to the Premises or any property or business of Lessor or Lessee
caused by any of the perils covered by public liability, fire and extended
coverage, building and contents, and business interruption insurance or for
which either party may be reimbursed as a result of insurance coverage affecting
any loss suffered by it; provided, however, that the foregoing waiver will apply
only to the extent of any recovery made by the parties hereto under any policy
of insurance now or hereafter issued and further provided that the foregoing
waivers do not invalidate any policy of insurance of the parties hereto now or
hereafter issued, it being stipulated by the parties that the foregoing waiver
will not apply in any such case in which the application thereof would result in
the invalidation of any such policy of insurance. In the event any additional
premium will be charged for such waiver provision the party benefitted by such
waiver will pay the cost of such endorsement.

VIII. INDEMNITY AND RIGHT OF ENTRY. Lessee will indemnify and hold harmless
Lessor from all claims, demands and damages for injuries to persons or property
arising from or in any manner connected with the occupancy or use of the demised
premises by Lessee, and from any and all other claims, demands, liens, damages,
fines or penalties of whatever name, nature of kind, in any way or manner
chargeable to, or payable for, or in respect of the use or occupancy of the
demised premises by Lessee, or from any act or omission of Lessee, its servants,
its agents, representatives, Lessees, guests, invitees, licensees or any other
person, firm or corporation in, about or adjacent to the demised premises.
Lessee will pay all costs, expenses and attorneys' fees incurred by or imposed
on Lessor in prosecution or defense of any suit, action or proceeding predicated
upon an alleged breach of undertaking by Lessee under the terms of this Lease or
for or on account of which Lessee has covenanted to indemnify Lessor under the
terms of this Lease or would be bound by law to so indemnify Lessor.

         Lessee covenants and agrees that Lessor, or Lessor's agents or
representatives, shall have the right, during normal business hours, to enter
upon the demised premises for the purpose of examining the same and to observe
the compliance or noncompliance by Lessee with the terms of this Lease, and for
the purpose of exhibiting the same to prospective lessees during the last six
(6) months of this Lease or as otherwise agreed between the parties. Lessee
agrees to permit Lessor or Lessor's agents or representatives to enter into and

premises or any portion thereof, without first obtaining the prior written
consent of Lessor, not to be unreasonably withheld. Any consent by Lessor to a
assignment or subletting shall not in any manner be construed to relieve Lessee

primarily liable for the payment of Base Rent herein reserved and for the
performance of all of the other terms of this Lease required to be performed by

condition, covenant or obligation to be performed within such thirty (30) day
period cannot, due to its nature, be performed within such thirty (30) day
period and Lessee commences or perform within such thirty (30) day period, and
thereafter diligently undertakes to complete the same.

<PAGE>   9

         B. Upon the occurrence of any event of default, as set forth above,
Lessor shall have the following rights and remedies, in addition to those
allowed by law or equity, and one or more of which may be exercised after ten
(10) days notice to Lessee:

                  1. Lessor may apply the security deposit and/or re-enter the
demised premises and cure any default of Lessee, in which event Lessee shall
reimburse Lessor as additional rent for any cost and expenses which Lessor may
incur to cure such default.

                  2. Lessor may terminate this Lease as of the date of such
default, in which event: (i) neither Lessee, nor any person claiming under or
through Lessee, shall thereafter be entitled to possession of the premises, and
Lessee shall immediately thereafter surrender the premises to Lessor; (ii)
Lessor may re-enter the premises and dispossess Lessee or any other occupants of

may sustain by reason of such termination, re-entry and re-letting, it being

for any loss resulting from the breach.

XIV. WAIVER. It is further mutually covenanted and agreed between the parties
hereto that no waiver of any covenant, agreement, stipulation or condition of
this Lease shall be construed to be a waiver of any succeeding breach of the
same covenant, agreement, stipulation or condition; that the payment by Lessee,
or the receipt by Lessor, of rent with knowledge of the breach by the other
party of any covenant hereof shall not be deemed a waiver of such breach; and
further, that all covenants, stipulations, conditions, and agreements herein
contained shall run with the land, and bind and inure to the benefit of, as the
case may require, the heirs, executors, administrators, successors and assigns
of the parties hereto and to grantees of Lessor, as fully as if such words were
written whenever reference to Lessor and Lessee occur in this Lease, except that
no assignment by lessee in violation of the provisions of this Lease, shall vest
any right in the assignee.

<PAGE>   10

XV. MORTGAGES. Lessor shall have the right to transfer, assign, mortgage and
convey in whole or in part, the demised premises, and any and all rights of
Lessor under this Lease, and nothing herein shall be construed as a restriction
upon Lessor so doing. This Lease shall be subject and subordinate to any
mortgage or other financing arrangement and to any renewal modification,
consolidation, replacement and extension thereof now or thereafter placed upon
or affecting the demised premises, or any part hereof, provided that so long as
Lessee is not in default of any of the terms and conditions hereof, Lessee's
rights, privileges and possession hereunder shall not be disturbed. Although no
instrument or act on the part of Lessee shall be necessary to effectuate such
subordination, Lessee will, upon request, execute and deliver such further
instruments subordinating this Lease to the lien of any such mortgages or other
financing arrangements as may be desired by the mortgagee or other lender.
Lessee hereby appoints Lessor its attorney-in-fact, irrevocably, to execute and
deliver any such instrument for Lessee, should Lessee fail to execute and
deliver same within five (5) days of any request therefor. In the event of any

XVI. CONDEMNATION.

         A. If, during the term of this Lease, all of the demised premises, or
such a substantial part of the premises so as to render the remaining as the
same may be restored, unusable for the purposes for which the premises were
leased, shall be taken by appropriation for public, or quasi-public use, under
the right of eminent domain, then all of the proceeds of such appropriation
shall be paid to Lessor, and Lessee shall have no claim to any part thereof,
except as set out below, and this Lease shall be canceled as of the date of such
taking, provided, however, Lessee may claim such damages it suffered with
respect to its trade fixtures, personal property and its improvements to the
real property from the condemning authority.

         B. If, during the term of this Lease, a part but not all of the demised
premises shall be taken by appropriation for public, or quasi-public use, under
the right of eminent domain and this Lease shall not terminate or be terminated
under the provisions of subparagraph XVI. A. hereof, then this Lease shall not
be canceled, and shall apply to that part of the demised premises not so taken.
In such event, all of the proceeds shall be paid to Lessor, and Lessee shall not
be entitled to any part thereof (except for a reasonable amount for the
depreciated value of its improvements), but the rental for the remaining term
and the Required Purchase Price, as defined below, shall be equitably adjusted.

XVII. LIENS. Lessor shall have a first and best lien, paramount to all others
upon every right and interest of Lessee to and in the demised premises and to

estate constituting the premises, as security for the payment of the entire
amount of Base Rent payable under this Lease, and for the payment of the entire
amount of Base Rent payable under this Lease, and for the payment of all monies
payable under any obligation or engagement of Lessee contained in this Lease,
and as security for the performance and observance of all and singular the

its expense, shall cause the demised premises to comply with all federal, state,
county, municipal and other governmental laws, statutes, rules, orders,
regulations and ordinances applicable to the demised premises, or any part
thereof or the use thereof, whether or not any such statutes, laws, rules,
orders, regulations or ordinances which may hereafter be enacted, involve a
change of policy, only to the extent that such compliance is the direct result
of Lessee's particular use of the premises. Any compliance that is necessary due
to the general use of the building at 5481 Creek Road, Cincinnati, Ohio shall be
the responsibility of Lessor. Lessee shall obtain and pay for all permits and
appraisals required for Lessee's occupancy of the demised premises, and shall
promptly take all substantial and non-substantial actions necessary to comply
with all statues, ordinances, rules, regulations, orders and requirements
regulating by Lessee's particular use of the demised premises, including,

Ohio. All materials used or kept on or about the demised premises shall be
self-contained in governmentally approved containers which shall not be opened,

resource damages, and diminution in value of the demised premises, or arising
out of the presence of hazardous waste, bio-hazardous waste, asbestos, petro
chemicals, toxic substances or the presence of other environmentally detrimental
matter. Without limiting the foregoing, Lessee shall acquire all applicable
permits required for the demised premises regarding stormwater discharges or
run-off, including any National Pollutant Discharges elimination system permits,
and shall comply with all applicable requirements, including monitoring
requirements. Lessor, at its option, may elect to acquire permits, perform any

any kind or nature. Lessee shall only use the demised premises as follows:

scope or intent of this Lease or affect this Lease.

record this Lease, a short form memorandum of Lease shall be recorded in lieu of
the original Lease. Such short form memorandum shall be executed by both
parties, but shall not in any way vary or revoke the terms of this Lease.

XXI. ESTOPPEL CERTIFICATE. Lessee shall from time to time, upon not less than
ten (10) days prior written request by Lessor, execute, acknowledge and deliver
to Lessor an estoppel certificate, certifying that this Lease is in full force
and effect; the dates to which rents have been

<PAGE>   12

paid; and whether Lessor is in default, and if so, specifying the nature of the
default; and that the Lease is in full force and effect, as modified, and
listing instruments of modification. It is intended that such estoppel
certificate may be relied on by a prospective purchaser of Lessor's interest, or
mortgagee or assignee of any mortgage upon the demised premises.

XXII. SECURITY DEPOSIT. Lessee has already deposited with Lessor the sum of Six
Thousand Two Hundred Fifty Dollars ($6,250.00), the receipt of which is hereby
acknowledged, as security for the payment by Lessee of the Base Rent or other
charges to be paid and for the faithful performance by Lessee of all of the
terms, conditions and covenants of this Lease. If at any time during the term of
this Lease, Lessee shall be in default in the performance of any provisions of
this Lease, Lessor shall have the right to use the security deposit, or so much
thereof as is necessary, in payment of rental or other charges in default,
reimbursement of any expenses incurred by Lessor, and in payment of any damages
incurred by Lessor by reason of Lessee's default. If any portion of said deposit
is so used or applied, Lessee shall, within ten (10) days after written demand
therefore from Lessor, remit to Lessor a sufficient amount out restore the
security deposit to its original amount. If claims of Lessor exceed the security
deposit, Lessee shall remain liable for the balance of such claims.

         In the event the security deposit has not been utilized as aforesaid,
the security deposit, or so much thereof as has not been utilized for such
purposes, shall be refunded to Lessee, without interest, upon full performance
of all of the terms of this Lease by Lessee.

         Lessor shall have the right to commingle the security deposit with
other funds of Lessor. Lessor shall have the right to deliver the security
deposit to any successor in interest to Lessor's interest in the demised
premises. Thereupon, Lessor shall be discharged from further liability with
respect to such security deposit.

         Lessee may not assign its right to the security deposit in whole or in
part.

XXIII. NO COUNTERCLAIM, ABATEMENT, ETC. There shall be no abatement, deduction
or offset whatsoever with regard to any amounts due from the Lessee to the
Lessor under this Lease.

XXIV. LIMITATION OF LESSOR'S PERSONAL LIABILITY. Lessee specifically agrees to
look solely to Lessor's interest in the Real Property and the Building for the
recovery of any judgment from Lessor, it being agreed that neither Lessor nor
any of its partners shall ever be personally liable for any such judgment. The
provision contained in the foregoing sentence is not intended to, and shall not,
limit any right that might otherwise have to obtain injunctive relief against
Lessor or Lessor's successors in interest, or any other action not involving the
personal liability of Lessor.

XXV. HOLDING OVER. In the event of holding over by Lessee after expiration or
termination of this Lease, Lessee shall pay double the Base Rent (calculated on
the basis of Base Rent with respect to the month immediately preceding the month
in which expiration or termination occurs) for the entire holdover period. No
holding over by Lessee after the term of this Lease shall be construed to extend
the term of this Lease. In the event of any unauthorized holding over, Lessee
shall also indemnify Lessor against all claims for damages by any other Lessee
to whom Lessor may have leased all or any part of the demised premises covered
hereby effective upon the

<PAGE>   13

termination of this Lease. Any holding over with the consent of Lessor in
writing shall thereafter constitute this Lease a lease from month to month.

XXVI. LESSEE'S RIGHT OF TERMINATION. At any time after January 31, 2001, Lessee
may give Lessor one hundred twenty (120) days notice to terminate this Lease. At
the end of said one hundred twenty (120) day period, said Lease shall be
terminated provided that Lessee pays to Lessor, in a lump sum, an early
termination penalty of one half of the rent for the remaining months of this
Lease. Notwithstanding the foregoing, in the event that upon the termination of
this Lease, Lessee leases new space in property owned by Green Realty
Corporation, the termination penalty will be waived.

XXVII. MISCELLANEOUS.

         A. If any provision of this Lease or the application thereof to any
person or circumstance shall to any extent be invalid or unenforceable, the
remainder of this Lease, or the application of such provision to persons or

v.       "TRADING DAY" shall mean a day on which The New York Stock Exchange is
         open for trading.

                         SECTION 3 - ELIGIBLE EMPLOYEES
                         ------------------------------

                  a. IN GENERAL. Participation in the Plan is voluntary. All
Eligible Employees of an Employer are eligible to participate in the Plan. All
Eligible Employees granted options to purchase Shares hereunder shall have the
same rights and privileges as every other such Eligible Employee, and only
Eligible Employees of an Employer satisfying the applicable requirements of the
Plan will be entitled to be granted options hereunder.

                  b. LIMITATIONS ON RIGHTS. An Employee who otherwise is an
Eligible Employee shall not be entitled to purchase Shares under the Plan if
such purchase would cause such Eligible Employee to own Shares (including any
Shares which would be owned if such Eligible Employee purchased all of the
Shares made available for purchase by such Eligible Employee under all options
or rights then held by such Eligible Employee, whether or not then exercisable)
representing five percent (5%) or more of the total combined voting power or
value of each class of stock of the Company or any Subsidiary.

                   SECTION 4 - ENROLLMENT AND OFFERING PERIODS
                   -------------------------------------------

                  a. ENROLLING IN THE PLAN. To participate in the Plan, an
Eligible Employee must enroll in the Plan. Enrollment for a given Offering
Period will take place during the Enrollment Period for such Offering Period.
The Administrator shall designate the initial Enrollment Period and each
subsequent Enrollment Period and the Offering Period to which each Enrollment
Period relates. Participation in the Plan with respect to any one or more of the
Offering Periods shall neither limit nor require participation in the Plan for
any other Offering Period.

                  b. THE OFFERING PERIOD. Any Employee who is an Eligible
Employee and who desires to be granted options to purchase Shares hereunder must
enroll in accordance with the procedures established by the Administrator during
an Enrollment Period. Such authorization shall be effective for the Offering
Period immediately following such Enrollment Period. The duration of an Offering
Period shall be determined by the Administrator prior to the Enrollment Period
and shall commence on the first day (or the first Trading Day) of the Offering
Period and end on the last day (or the last Trading Day) of the Offering Period;
provided, however, that if the Administrator terminates the Plan during an
Offering Period, pursuant to its authority in Section 17 of the Plan, such
Offering Period shall be deemed to end on the date the Plan is terminated. The
termination of the Plan and the Offering Period shall end the Participant's
rights to contribute amounts to the Plan or continue participation in the
Offering Period. The date of termination of the Plan shall be deemed to be the
final day of the Offering Period for purposes of determining the Purchase Price
under the Offering Period and all amounts contributed during the Offering Period
will be used as of such termination date to purchase Shares in accordance with
the provisions of Section 9 of this Plan.

                  The Administrator may designate one or more Offering Periods
during each Plan Year during the term of this Plan. On the first day (or the
First Trading Day) of each Offering Period, each Participant shall be granted an
option to purchase Shares under the Plan. Each option granted hereunder shall
expire at the end of the Offering Period for which it was granted. In no event
may an option granted hereunder be exercised after the expiration of 27 months
from the date of grant.

                  c. CHANGING ENROLLMENT. The offering of Shares pursuant to
options granted under the Plan shall occur only during an Offering Period and
shall be made only to Participants. Once an Eligible Employee is

<PAGE>   4

enrolled in the Plan, the Administrator or Employer will inform the Agent of
such fact. Once enrolled, a Participant shall continue to participate in the
Plan for each successive Offering Period (s) until he or she terminates his or
her participation by revoking his or her payroll deduction authorization or by
revoking his or her alternative contribution authorization or not contributing
his or her alternative contributions or ceases to be an Eligible Employee. Once
a Participant has elected to participate under the Plan, that Participant's
payroll deduction authorization or alternative contribution authorization shall
apply to all subsequent Offering Periods unless and until the Participant ceases
to be an Eligible Employee, or modifies or terminates said authorization. If a
Participant desires to change his or her rate of contribution, he or she may do
so effective for the next Offering Period by following the procedures
established by the Administrator during the Enrollment Period immediately
preceding such Offering Period.

                            SECTION 5 - TERM OF PLAN
                            ------------------------

                  This Plan shall be in effect from July 1, 2000, until it is
terminated by action of the Board.

                SECTION 6 - NUMBER OF SHARES TO BE MADE AVAILABLE
                -------------------------------------------------

                  Subject to adjustment as provided in Section 16 hereof, the
total number of Shares made available for purchase by Participants granted
options which are exercised under Section 9 hereof is 3 million, which may
consist of authorized but unissued shares, treasury shares, or shares purchased
by the Plan in the open market. The provisions of Section 9 b. shall control in
the event the number of Shares covered by options which are exercised for any
Offering Period exceeds the number of Shares available for sale under the Plan.
If all of the Shares authorized for sale under the Plan have been sold, the Plan
shall either be continued through additional authorizations of Shares made by
the Board (such authorizations must, however, comply with Section 17 hereof), or
shall be terminated in accordance with Section 17 hereof.

                            SECTION 7 - USE OF FUNDS
                            ------------------------

                  All payroll deductions or alternative contributions received
or held by an Employer under the Plan will be used to purchase Shares in
accordance with the provisions of this Plan. Any amounts held by an Employer or
other party holding amounts in connection with or as a result of payroll
withholding or alternative contribution made pursuant to the Plan and pending
the purchase of Shares hereunder shall be considered a non-interest-bearing,
unsecured indebtedness extended to the Employer or other party by the
Participants, unless otherwise required under applicable local law or securities
regulatory body requirements of the country in which the Employer of the
Employee is located or the Employee is employed or resides, as the case may be.
Administrative expenses of the Plan shall be allocated to each Participant's
Plan Account unless such expenses are paid by the Employer.

              SECTION 8 - AMOUNT OF CONTRIBUTION; METHOD OF PAYMENT
              -----------------------------------------------------

                  a. PAYROLL WITHHOLDING OR PAYROLL DEDUCTION OR ALTERNATIVE
CONTRIBUTIONS. Except as otherwise specifically provided herein, the Purchase
Price will be payable by each Participant by means of payroll withholding. The
withholding or alternative contributions shall be in increments of one percent
(1%). Unless otherwise authorized by the Administrator, the minimum withholding
or alternative contributions permitted shall be an amount equal to one percent
(1%) of a Participant's Compensation and the maximum withholding or alternative
contributions shall be an amount equal to fifteen percent (15%) of a
Participant's Compensation. In any event, the total withholding or alternative
contributions permitted to be made by any Participant for a calendar year shall
be limited to the sum of legal currency equivalent of U.S. $21,250. The actual
percentage of Compensation to be deducted or contributed shall be specified by a
Participant in his or her authorization to participate in the Plan. Unless
otherwise authorized by the Administrator, Participants may not deposit any
separate cash payments into their Plan Accounts.

                  b. APPLICATION OF WITHHOLDING RULES. Payroll withholding will
commence with the first payroll issued during the Offering Period and will,
except as otherwise provided herein, continue with each payroll throughout the
entire Offering Period, except for pay periods for which such Participant
receives no compensation (e.g., uncompensated personal leave, leave of absence).
A pay period which ends at such time that it is

<PAGE>   5

administratively impracticable to credit any payroll for such pay period to the
then-current Offering Period will be credited in its entirety to the immediately
subsequent Offering Period. A pay period which overlaps Offering Periods will be
credited in its entirety to the Offering Period in which it is paid. Alternative
contributions will be made in accordance with the procedure established by the
Administrator. Payroll withholding or alternative contributions shall be
retained by the Employer or other party, designated by the Administrator or the
Employer as the case may be, until applied to the purchase of Shares as
described in Section 9 hereof and the satisfaction of any related federal,
state, local or other tax withholding obligations (including any employment tax
obligations).

                  At the time the Shares are purchased, or at the time some or
all of the Shares issued under the Plan are disposed of, Participants must make
adequate provision for the Employer's federal, state, local or other tax
withholding obligations (including employment taxes), if any, which arise upon
the purchase or disposition of the Shares. At any time, the Employer may
withhold from each Participant's Compensation the amount necessary for the
Employer to meet applicable withholding obligations, including any withholding
required to make available to the Employer any tax deductions or benefits
attributable to the sale or early disposition of Shares by the Participant. Each
Participant, as a condition of participating under the Plan, agrees to bear
responsibility for all federal, state, local and other income taxes required to
be withheld from his or her Compensation as well as the Participant's portion of
FICA (both the OASDI and Medicare components), and other applicable social
security or similar such taxes, with respect to any Compensation arising on
account of the purchase or disposition of Shares. The Employer may increase
income and/or employment tax withholding on a Participant's Compensation after
the purchase or disposition of Shares in order to comply with federal, state,
local and other tax laws, and each Participant agrees to sign any and all
appropriate documents to facilitate such withholding.

                   SECTION 9 - PURCHASING, TRANSFERRING SHARES
                   -------------------------------------------

                  a. MAINTENANCE OF PLAN ACCOUNT. Upon the exercise of a
Participant's initial option to purchase Shares under the Plan, the Agent shall
establish a Plan Account in the name of such Participant. At the close of each
Offering Period, the aggregate amount deducted during such Offering Period by
the Employer from a Participant's Compensation, or alternative contributions
made to the Plan by the Participant (and credited to an account maintained by
the Employer or other party for bookkeeping purposes) will be communicated by
the Employer to the Agent and shall thereupon be credited by the Agent to such
Participant's Plan Account (unless the Participant has given notice to the
Administrator of his or her revocation of authorization prior to the date such
communication is made). As of the last day of each Offering Period, or as soon
thereafter as is administratively practicable, each Participant's option to
purchase Shares will be exercised automatically for him or her by the Agent with
respect to those amounts reported to the Agent by the Administrator or Employer
as creditable to that Participant's Plan Account. On the date of exercise, the
amount then credited to the Participant's Plan Account for the purpose of
purchasing Shares hereunder will be divided by the Purchase Price and there
shall be transferred to the Participant's Plan Account by the Agent the number
of whole and/or fractional shares which results, as permitted by local law.

                  The Agent shall hold in its name, or in the name of its
nominee, all Shares so purchased and allocated. No certificate will be issued to
a Participant for Shares held in his or her Plan Account unless he or she so
requests in writing or unless such Participant's active participation in the
Plan is terminated due to death, disability, separation from service or
retirement. Participation in the Plan, purchase, ownership and sale of Shares
under the Plan, is subject to risk of fluctuation in Shares' price and currency
exchange.

                  b. INSUFFICIENT NUMBER OF AVAILABLE SHARES. In the event the
number of Shares covered by options which are exercised for any Offering Period
exceeds the number of Shares available for sale under the Plan, the number of
Shares actually available for sale hereunder shall be limited to the remaining
number of Shares authorized for sale under the Plan and shall be allocated by
the Agent among the Participants in proportion to each Participant's
Compensation during the Offering Period over the total Compensation of all
Participants during the Offering Period. Any excess amounts withheld and
credited to Participants' Plan Accounts then shall be returned to the
Participants as soon as is administratively practicable.

                  c. HANDLING EXCESS SHARES. In the event that the number of
Shares which would be credited to any Participant's Plan Account in any Offering
Period exceeds the limit specified in Section 3 b. hereof, such

<PAGE>   6

Participant's Plan Account shall be credited with the maximum number of Shares
permissible, and the remaining amounts will be refunded in cash as soon as
administratively practicable.

                  d. STATUS REPORTS. Statements of each Participant's Plan
Account shall be given to Participants at least annually.

                 SECTION 10 - DIVIDENDS AND OTHER DISTRIBUTIONS
                 ----------------------------------------------

                  a. REINVESTMENT OF DIVIDENDS. Subject to applicable law, cash
dividends and other cash distributions received by the Agent on Shares held in
its custody hereunder will be credited to the Plan Accounts of individual
Participants in accordance with such Participants' interests in the Shares with
respect to which such dividends or distributions are paid or made, and will be
applied, as soon as practical after the receipt thereof by the Agent, to the
purchase in the open market at prevailing market prices of the number of whole
Shares capable of being purchased with such funds (after deduction of any bank
service fees, brokerage charges, transfer taxes, and any other transaction fee,
expense or cost payable in connection with the purchase of such Shares and not
otherwise paid by the Employer and subject to the Company's obligation to
withhold federal, state, or other local taxes ).

                  b. SHARES TO BE HELD IN AGENT'S NAME. All purchases of Shares
made pursuant to this Section will be made in the name of the Agent or its
nominee, shall be held as provided in Section 9 hereof, and shall be transferred
and credited to the Plan Account(s) of the individual Participant(s) to which
such dividends or other distributions were credited. Dividends paid in the form
of Shares will be allocated by the Agent, as and when received, with respect to
Shares held in its custody hereunder to the Plan Accounts of individual
Participants in accordance with such Participants' interests in such Shares with
respect to which such dividends were paid. Property, other than Shares or cash,
received by the Agent as a distribution on Shares held in its custody hereunder,
shall be sold by the Agent for the accounts of the Participants, and the Agent
shall treat the proceeds of such sale in the same manner as cash dividends
received by the Agent on Shares held in its custody hereunder.

                  c. TAX RESPONSIBILITIES. The automatic reinvestment of
dividends under the Plan will not relieve a Participant (or Eligible Employee
with a Plan Account) of any income or other tax that may be due on or with
respect to such dividends. The Agent shall report to each Participant (or
Eligible Employee with a Plan Account) the amount of dividends credited to his
or her Plan Account.

                          SECTION 11 - VOTING OF SHARES
                          -----------------------------

                  A Participant shall have no interest or voting right in the
Shares covered by his or her option until such option has been exercised. Shares
held for a Participant (or Eligible Employee with a Plan Account) in his or her
Plan Account will be voted in accordance with the Participant's (or Eligible
Employee's) express directions. In the absence of any such directions, such
Shares will not be voted.

             SECTION 12 - IN-SERVICE DISTRIBUTION OR SALE OF SHARES
             ------------------------------------------------------

                  a. SALE OF SHARES. Subject to the provisions of Section 19
hereof, a Participant may at any time, and without withdrawing from the Plan, by
giving notice to the Agent, direct the Agent to sell all or part of the Shares
held on behalf of the Participant. Upon receipt of such a notice, the Agent
shall, as soon as practicable after receipt of such notice, sell such Shares in
the marketplace at the prevailing market price and transmit the net proceeds of
such sale (less any bank service fees, brokerage charges, transfer taxes, and
any other transaction fee, expense or cost) to the Participant.

                  b. IN-SERVICE SHARE DISTRIBUTIONS. A Participant may, without
withdrawing from the Plan, request that a certificate for all or part of the
whole number of Shares held in his or her Plan Account be sent to him or her
after the relevant Shares have been purchased and allocated subject to the
requirement that such Shares be held in the Participant's Plan Account for a
period of at least 24 months after the date of exercise, as described in Section
9 a., above. All such requests must be submitted in writing to the Agent. No
certificate for a fractional Share will be issued; the fair value of fractional
Shares on the date of withdrawal of all Shares credited to a Participant's Plan
Account shall be paid in cash to such Participant. The Plan may impose a
reasonable charge, to be paid by the Participant, for each stock certificate so
issued prior to the date active participation in the Plan ceases;

<PAGE>   7

such charge shall be paid by the Participant to the Administrator or Employer
prior to the date any distribution of a certificate evidencing ownership of such
Shares occurs.

                 SECTION 13 - CESSATION OF ACTIVE PARTICIPATION
                 ----------------------------------------------

                  A Participant may at any time, by giving notice to the
Administrator or Employer, revoke his or her authorization for payroll deduction
or alternative contributions for the Offering Period in which such revocation is
made. A Participant who revokes authorization or does not make alternative
contributions for payroll deduction may not again participate under the Plan
until the next Offering Period immediately subsequent to the Offering Period
during which the Participant revoked payroll deduction authorization or did not
make alternative contributions with respect thereto.

                     SECTION 14 - SEPARATION FROM EMPLOYMENT
                     ---------------------------------------

                  Separation from employment for any reason, including death,
disability, termination or retirement shall be deemed to be a cessation of
active participation in the Plan as described under Section 13 hereof.

                             SECTION 15 - ASSIGNMENT
                             -----------------------

                  Neither payroll deductions nor alternative contributions
credited to a Participant's Plan Account nor any rights to purchase Shares under
the Plan may be assigned, alienated, transferred, pledged, or otherwise disposed
of in any way by a Participant other than by will or the laws of descent and
distribution. Any such assignment, alienation, transfer, pledge, or other
disposition shall be without effect, except that the Administrator may treat
such act as an election to withdraw from the Plan. A Participant's right to
purchase Shares under this Plan may be exercisable during the Participant's
lifetime only by the Participant. A Participant's Plan Account shall be payable
to the Participant's estate upon his or her death.

                SECTION 16 - ADJUSTMENT OF AND CHANGES IN SHARES
                ------------------------------------------------

                  If at any time after the effective date of the Plan the
Company shall subdivide or reclassify the Shares which have been or may be
optioned under the Plan, or shall declare thereon any stock split or dividend
payable in Shares, or shall alter the capital structure of the Shares or the
Company in any similar manner, then the number and class of shares held in the
Plan and which may thereafter be optioned (in the aggregate and to any
Participant) shall be adjusted accordingly, and in the case of each option
outstanding at the time of any such action, the number and class of shares which
may thereafter be purchased pursuant to such option and the Purchase Price shall
be adjusted accordingly, as necessary to preserve the rights of the holder(s) of
such Shares and option(s).

                SECTION 17 - AMENDMENT OR TERMINATION OF THE PLAN
                -------------------------------------------------

                  The Board shall have the right, at any time, to amend, modify
or terminate the Plan without notice; provided, however, that no Participant's
existing options shall be adversely affected by any such amendment, modification
or termination, except to comply with applicable law, stock exchange rules or
accounting rules. Notwithstanding the foregoing, the Board shall have the right
to terminate the Plan with respect to all future payroll deductions and related
purchases at any time. Such termination of the Plan shall also terminate any
current Offering Period in accordance with Section 4 of the Plan.

                  Designations of participating corporations may be made from
time to time from among a group of corporations consisting of the Employer, its
parent and its Subsidiaries (including corporations that become Subsidiaries or
a parent after the adoption and approval of the Plan).

                  The Company may amend or modify the Plan or make regulations
for the operation of the Plan that are not inconsistent with these rules to
apply to Employees and Participants who are employed or resident outside of the
United States of America in accordance with the relevant law. "Relevant law"
shall mean the applicable law of the jurisdiction in which the Employer of the
Employee is located or where the Employee is employed or resides and the
securities regulatory body requirements and the taxation requirements of that
same jurisdiction.

                           SECTION 18 - ADMINISTRATION
                           ---------------------------

                  a. ADMINISTRATION. The Plan shall be administered by the
Administrator. The Administrator shall be responsible for the administration of
all matters under the Plan which have not been delegated to the Agent. The
Administrator shall have full and exclusive discretionary authority to construe,
interpret and apply the terms of the Plan, to determine eligibility and to
adjudicate all disputed claims filed under the Plan. Any rule or regulation
adopted by the Administrator shall remain in full force and effect unless and
until altered, amended or repealed by the Administrator.

                  b. SPECIFIC RESPONSIBILITIES. The Administrator's
responsibilities shall include, but shall not be limited to:

                     (1)      interpreting the Plan (including issues
                     relating to the definition and application of
                     "Compensation");

                     (2)      identifying and compiling a list of persons
                      who are Eligible Employees for an Offering Period;

                     (3)      identifying  those Eligible Employees not
                     entitled to be granted options or other rights for
                     an Offering  Period on account of the limitations
                     described in Section 3 b. hereof; and

                     (4)      providing to Participants upon request
                     Company financial statements which are publicly
                     available.

The Administrator may from time to time adopt rules and regulations for carrying
out the terms of the Plan. Interpretation or construction of any provision of
the Plan by the Administrator shall be final and conclusive on all persons,
absent specific and contrary action taken by the Board. Any interpretation or
construction of any provision of the Plan by the Board shall be final and
conclusive.

               SECTION 19 - SECURITIES LAW AND OTHER RESTRICTIONS
               --------------------------------------------------

                  Notwithstanding any provision of the Plan to the contrary, no
payroll deductions or alternative contributions shall take place and no Shares
may be purchased under the Plan until a registration statement has been filed
and become effective with respect to the issuance of the Shares covered by the
Plan under the Act and any other required action has been taken under any other
applicable law of the jurisdiction in which the Employer of the Employee is
located or the Employee is employed or resides. Prior to the effectiveness of
such registration statement, Shares subject to purchase under the Plan may be
offered to Eligible Employees only pursuant to an exemption from the
registration requirements of the Act and pursuant to any other action that is
required under any other applicable law of the jurisdiction in which the
Employer of the Employee is located or the Employee is employed or resides.

                  SECTION 20 - NO INDEPENDENT EMPLOYEE'S RIGHTS
                  ---------------------------------------------

                  Nothing in the Plan shall be construed to be a contract of
employment between an Employer or its parent or any Subsidiary and any Employee,
or any group or category of Employees (whether for a definite or specific
duration or otherwise), or to prevent the Employer, its parent or any Subsidiary
from terminating any Employee's employment at any time, without notice or
recompense to the extent permissible under local law. Nothing in this Plan shall
be construed as conferring any rights of a shareholder in any Employee or any
other person until the option to purchase shares granted to the Employee
hereunder has been exercised.

                           SECTION 21 - APPLICABLE LAW
                           ---------------------------

                  The Plan shall be construed, administered and governed in all
respects under the laws of the State of Ohio to the extent such laws are not
preempted or controlled by federal law.

<PAGE>   9

                      SECTION 22 - MERGER OR CONSOLIDATION
                      ------------------------------------

                  If the Company shall at any time merge into or consolidate
with another corporation or business entity, each Participant will thereafter be
entitled to receive at the end of the Offering Period (during which such merger
or consolidation occurs) the securities or property which a holder of Shares was
entitled to upon and at the time of such merger or consolidation. A sale of all
or substantially all of the assets of the Company shall be deemed a merger or
consolidation for the foregoing purposes.
