WHEREAS, Landlord and Tenant desire to expand the Original Premises by
approximately 79,385 rentable square feet (the "Additional Space") in an
approximately 153,686 square foot office building to be constructed commonly
known as Woodland Corporate Park VI. Collectively, the Original Premises and
Additional Space shall hereinafter be referred to as the "Leased Premises"; and

WHEREAS, Landlord and Tenant desire to amend certain provisions of the Lease to
reflect such expansion and any other changes to the Lease;

NOW, THEREFORE, in consideration of the foregoing premises, the mutual covenants
herein contained and each act performed hereunder by the parties, Landlord and
Tenant hereby enter into this Amendment.
 
1. Incorporation of Recitals. The above recitals are hereby incorporated into
this Amendment as if fully set forth herein.

2. Amendment of Article 1. Lease of Premises.

(a) Commencing on (i) March 1, 2008; (ii) such later date upon which the First
Takedown Space Tenant Improvements described in Exhibit B-5 hereof are
Substantially Completed (as defined in Exhibit B-5), provided, however, that
such date shall not be extended as a result of any Tenant Delay (as defined in
Exhibit B-5) and Substantial Completion shall be deemed to have occurred upon
the date that it would have occurred but for such Tenant Delay; or (iii) upon
such earlier date as Tenant begins conduct of its business in any part of the
first takedown space (as hereinafter defined) (the "First Takedown Space
Commencement Date"), Section 1.01 of Article 1 of the Lease is hereby amended by
substituting Third Amended Exhibit A, attached hereto and incorporated herein by

comparable temporary space as near as possible to Woodland Corporate Park V at
no cost to Tenant until the appropriate Additional Space is substantially
complete. The term "availability" as used above means vacant office space owned
by Landlord which has not been leased to another tenant or for which a letter of

referred to as the "Building", unless otherwise specifically provided in this
Amendment). Woodland V is located on the land identified as the "Woodland V
Land" on Second Amended Exhibit A-1 and Woodland VI is located on the land
identified as the "Woodland VI Land" on Second Amended Exhibit A-1. Unless

commencing on the First Takedown Space Commencement Date, an additional
approximately 39,693 rentable square feet in Woodland VI; commencing September

For purposes of this Lease, the Building Owners and Managers Association
International ("BOMA") Standard Method for Measuring Floor Area In Office
Buildings American National Standard ANSI-Z65.1-1996 approved June 7, 1996 by
American National Standards Institute, Inc. ("BOMA Standards") shall be utilized
to determine the useable area of the Additional Space and the usable area of the
Woodland VI. The Rentable Area shall include the area within the Additional
Space plus a pro rata portion of the area covered by the common areas within
Woodland VI, as reasonably determined by Landlord prior to Tenant's occupancy of
the appropriate Additional Space. Landlord's determination of Rentable Area in
the manner provided shall be deemed correct for all purposes hereunder;
provided, however, Tenant or Landlord shall have the right, at any time prior to
the earlier of (i) the commencement date for the applicable Additional Space, or
(ii) within fifteen (15) days after the construction of Woodland VI has
progressed to the stage necessary for Tenant to be able to measure all of the
Additional Space in accordance with BOMA Standards and Landlord has notified
Tenant in writing of the same, to have the applicable Additional Space (in the
case of (i) above) or the entire Additional Space (in the case of (ii) above)
and Woodland VI measured by Tenant's architect or, if such measurement is
requested by Landlord, by Landlord's architect (which measurement Tenant's
architect or Landlord's architect, as applicable, shall certify has been made in
accordance with BOMA Standards) and, in the event of a disparity with the
rentable square footage originally estimated in the first sentence of this
Section 1.01B (the "Originally Estimated Area"), either (a) Landlord and Tenant
shall mutually agree on the Rentable Area of the applicable Additional Space (in
the case of (i) above) or entire Additional Space (in the case of ii above) and
the rentable area of the Woodland VI, or (b) Landlord and Tenant shall agree to
have the applicable Additional Space (in the case of (i) above) or the entire
Additional Space (in the case of (ii) above) and Woodland VI measured by an
independent architect (in accordance with BOMA standards) mutually agreed upon
by Landlord and Tenant, in which event Landlord and Tenant agree to abide by
such certified remeasurement. If the rentable square footage of the applicable
Additional Space (in the case of (i) above) or entire Additional Space (in the
case of (ii) above) or Woodland VI, as measured by said independent architect,
is one thousand (1,000) feet or more smaller than the Originally Estimated Area,
then the costs of said independent architect shall be borne by Landlord,
otherwise said costs shall be borne by Tenant. Upon determination of the actual
Rentable Area of the applicable Additional Space (in the case of (i) above) or
the entire Applicable Space (in the case of (ii) above) and rentable area of
Woodland VI, the Minimum Annual Rent and all other rents payable by Tenant
hereunder shall be adjusted to reflect the actual square footage.

zoning and other municipal and county regulations, (ii) Tenant and/or a
Permitted Transferee does not reduce, sublease (except to a Permitted
Transferee), or assign (except to a Permitted Transferee) the Additional Space
or any portion thereof, and (iii) there is no uncured Default by Tenant
hereunder, Tenant may, at its own cost and expense, erect two (2) signs
("Woodland VI Signs") identifying its business on Woodland VI. The location,
style and size of the Woodland VI Signs shall be consistent with Landlord's park
signage guidelines (a copy of which are attached hereto as Exhibit E) and
otherwise subject to Landlord's prior written approval, which shall not be
unreasonably withheld, conditioned or delayed. Notwithstanding the forgoing, (a)

Transferee still leases and occupies at least fifty percent (50%) of Woodland
VI, Tenant may maintain the Woodland VI Signs that have already been attached to
the Building (but may not attach any additional signs to the Building), and (b)
if Tenant fails to comply with item (ii) above but Tenant or a Permitted
Transferee still leases and occupies at least twenty-five percent (25%) of
Woodland VI, Tenant may maintain only one of the Woodland VI Signs and Tenant
shall remove the Woodland VI Sign of its choice if Tenant has previously
attached more that one sign to Woodland VI and repair all damage caused to
Woodland VI thereby. Tenant agrees to maintain such Woodland VI Signs in
first-class condition and in compliance with all zoning and building codes
throughout the Lease Term. Upon expiration or early termination of the Lease
Term with respect to the Additional Space, Tenant shall remove the Woodland VI
Signs and repair all damage to Woodland VI caused thereby, returning Woodland VI
to the condition existing prior to the installation of the Woodland VI Signs.
Landlord does not warrant the continuing availability of such Woodland VI Signs
to Tenant; however, Landlord agrees not to take any action which would negate
Tenant's ability to maintain such Signs and to provide reasonable cooperation to
Tenant in connection with any application required by Governmental Laws. Any
language in the Lease notwithstanding, Tenant shall indemnify and hold harmless
Landlord from any and all liability for any loss of or damage or injury to any
person (including death resulting therefrom) or property connected with or
arising from the Woodland VI Signs or the rights granted Tenant herein. The
obligations of Tenant herein shall survive the expiration or earlier termination
of this Lease."

Tenant's sole cost and expense and shall be subject to Landlord's approval.
Landlord may install such other signs, advertisements, notices or tenant
identification information on the Woodland VI directory, tenant access doors or
other areas of Woodland VI, as it shall deem necessary or proper. Tenant shall
not place any exterior signs on the portion of the Leased Premises located in
Woodland VI or interior signs visible from the exterior thereof without the
prior written consent of Landlord. Notwithstanding any other provision of this
Lease to the contrary, Landlord may immediately remove any sign(s) placed by
Tenant in violation of this Section 16.11D."
(d) Section 16.11 of the Lease is further amended by adding new Subparagraph E
as follows:

"E. Renaming of Portion of Innovation Blvd.; Monument Signage. At such time as
Tenant or its Permitted Transferee commences the payment of rent on all of the
Leased Premises and provided that Tenant or its Permitted Transferee continues
to lease and occupy all of the Leased Premises and Woodland V, (i) upon Tenant's
written request, Landlord shall use commercially reasonable efforts to cause the
applicable governmental authority to rename that portion of Innovation Boulevard
cross hatched on Exhibit F attached hereto, to "Interactive Way", and (ii)

to provide at its sole expense, a monument sign (as more particularly described

of the total number of parking spaces designated for Woodland VI by Landlord
based on Tenant's Building Expense Percentage from time to time. The parking
spaces designated for Woodland VI by Landlord are depicted on Second Amended
Exhibit A-1, attached hereto. Landlord shall maintain a parking ratio for
Woodland VI of four (4) parking spaces per 1000 rentable square feet of rentable
space in Woodland VI. Tenant agrees not to overburden the parking facilities and
agrees to cooperate with Landlord and other tenants in the use of the parking
facilities. Landlord reserves the right in its absolute discretion to determine
whether parking facilities are becoming crowded and, in such event, to allocate
parking spaces between Tenant and other tenants. There will be no assigned
parking unless Landlord, in its sole discretion, deems such assigned parking
advisable. No vehicle may be repaired or serviced in the parking area and any
vehicle brought into the parking area by Tenant, or any of Tenant's employees,
contractors or invitees, and deemed abandoned by Landlord will be towed and all
costs thereof shall be borne by the Tenant. All driveways, ingress and egress,
and all parking spaces are for the joint use of all tenants. There shall be no
parking permitted on any of the streets or roadways located within the park. In

portion of the Offer Space now or hereafter leased by such other tenant,
Landlord shall, before entering into a lease with a third party for space
containing 10,000 square feet or more located in Woodland Corporate Park
Building I ("Woodland I") (the particular space referred to in Landlord's Notice
(as defined below) being hereinafter referred to as the "Offer Space"), notify
Tenant in writing of the availability of the Offer Space for leasing and setting
forth the terms and conditions upon which Landlord is willing to lease the Offer
Space to Tenant ("Landlord's Notice"). Tenant shall have seven (7) business days
from its receipt of Landlord's Notice to deliver to Landlord a written notice
agreeing to lease the Offer Space on the terms and conditions contained in
Landlord's Notice ("Tenant's Acceptance"). In the event Tenant fails to deliver
Tenant's Acceptance to Landlord within said seven (7) business day period, such
failure shall be conclusively deemed a rejection of the Offer Space and a waiver
by Tenant of this right of first offer with respect to the Offer Space,
whereupon Tenant shall have no further rights with respect to the Offer Space
and Landlord shall be free to lease the Offer Space to a third party.
 
(b) The term for the Offer Space shall be coterminous with the term for the then
existing Leased Premises (the "Existing Premises"); provided, however, that the
minimum term for the Offer Space shall be five (5) years and the term for the
then Existing Premises shall be extended, if necessary, to be coterminous with
the term for the Offer Space. If the Lease Term for the Existing Premises is
extended as provided above, the Minimum Annual Rent for such extension term
shall be an amount equal to the Minimum Annual Rent then being quoted by
Landlord to prospective renewing tenants of the Building for space of comparable
size and quality and with similar or equivalent improvements as are found in the
Building, and if none, then in similar buildings in the Park; provided, however,
that in no event shall the Minimum Annual Rent during such extension term be
less than the highest Minimum Annual Rent payable during the immediately
preceding term.
 
(c) If Tenant properly exercises its right of first offer, Landlord and Tenant
shall enter into an amendment to this Lease adding the Offer Space to the Leased
Premises upon the terms and conditions set forth herein and making such other
modifications to this Lease as are appropriate under the circumstances. Landlord
and Tenant shall work diligently and in good faith to enter into such amendment
as promptly as reasonably possible.
 
(d) Notwithstanding anything to the contrary in this Section 16.24, if Tenant
properly exercises its right of first offer hereunder during the first five
years of the Lease Term for the Additional Space, (i) the rental rates
applicable to the applicable Offer Space will be the rental rates then in effect
for the Additional Space (and such rates shall escalate at the same time as the
rental escalations for the Additional Space), and (ii) Tenant shall receive the
same tenant improvement allowance ($24.00 per rentable square foot) for the
applicable Offer Space as was provided for the Additional Space, except that
such allowance shall be prorated based on the remaining lease term.

Section 16.25. Right of First Offer (Woodland VI).
 
(a) Provided that (i) no Default has occurred which remains uncured, (ii) the
creditworthiness of Tenant is then reasonably acceptable to Landlord, and (iii)
Tenant originally named herein or its Permitted Transferee remains in possession
of seventy-five percent (75%) or more of the Leased Premises, and subject to any
rights of other tenants to the Offer Space (as defined herein) and Landlord's
right to renew or extend the lease term of any other tenant with respect to the
portion of the Offer Space now or hereafter leased by such other tenant,
Landlord shall, before entering into a lease with a third party for space
located in Woodland VI (the particular space referred to in Landlord's Notice
(as defined below) being hereinafter referred to as the "Offer Space"), notify
Tenant in writing of the availability of the Offer Space for leasing and setting
forth the terms and conditions upon which Landlord is willing to lease the Offer
Space to Tenant ("Landlord's Notice"). Tenant shall have seven (7) business days
from its receipt of Landlord's Notice to deliver to Landlord a written notice
agreeing to lease the Offer Space on the terms and conditions contained in
Landlord's Notice ("Tenant's Acceptance"). In the event Tenant fails to deliver
Tenant's Acceptance to Landlord within said seven (7) business day period, such
failure shall be conclusively deemed a rejection of the Offer Space and a waiver
by Tenant of this right of first offer with respect to the Offer Space,
whereupon Tenant shall have no further rights with respect to the Offer Space
and Landlord shall be free to lease the Offer Space to a third party.
 
(b) The term for the Offer Space shall be coterminous with the term for the then
existing Leased Premises (the "Existing Premises"); provided, however, that the
minimum term for the Offer Space shall be five (5) years and the term for the
Existing Premises shall be extended, if necessary, to be coterminous with the
term for the Offer Space. If the Lease Term for the Existing Premises is
extended as provided above, the Minimum Annual Rent for such extension term
shall be an amount equal to the Minimum Annual Rent then being quoted by
Landlord to prospective renewing tenants of the Building for space of comparable
size and quality and with similar or equivalent improvements as are found in the
Building, and if none, then in similar buildings in the Park; provided, however,
that in no event shall the Minimum Annual Rent during such extension term be
less than the highest Minimum Annual Rent payable during the immediately
preceding term.
 
(c) If Tenant properly exercises its right of first offer, Landlord and Tenant
shall enter into an amendment to this Lease adding the Offer Space to the Leased
Premises upon the terms and conditions set forth herein and making such other
modifications to this Lease as are appropriate under the circumstances. Landlord
and Tenant shall work diligently and in good faith to enter into such amendment
as promptly as reasonably possible.
 
(d) Notwithstanding anything to the contrary in this Section 16.25, if Tenant
properly exercises its right of first offer hereunder during the first five
years of the Lease Term for the Additional Space, (i) the rental rates
applicable to the applicable Offer Space will be the rental rates then in effect
for the Additional Space (and such rates shall escalate at the same time as the
rental escalations for the Additional Space), and (ii) Tenant shall receive the
same tenant improvement allowance ($24.00 per rentable square foot) for the
applicable Offer Space as was provided for the Additional Space, except that
such allowance shall be prorated based on the remaining lease term.

Section 16. 26. Tax Abatement (Woodland VI).

(a) Landlord and Tenant acknowledge that, as of the date of this Amendment,
Tenant has obtained tax abatement on Woodland VI (the "Tax Abatement"). Landlord
agrees that Tenant shall receive the benefit of any Tax Abatement obtained by
Tenant on Woodland VI in accordance with the terms which follow below. During
the term of the Lease, within thirty (30) days after Landlord pays each
installment of Real Estate Taxes respecting Woodland VI, Landlord shall pay to
tenant a pro-rata portion of any Real Estate Taxes that were abated with respect
to the applicable installment based on the percentage of rentable square footage
of Woodland VI that is not, as of date Landlord pays such installment, leased by
Tenant or an affiliate thereof. The following provides a sample calculation of
Tenant's Real Estate Tax liability respecting Woodland VI for the fourth
calendar year of the Lease Term (for purposes of this example, the selection of
the fourth calendar year is arbitrary) based on the following assumptions: (i)
Tenant leases approximately 75,000 square feet, a third party tenant leases
approximately 25,000 square feet, and the remaining approximately 50,000 square
feet of Woodland VI is not leased by any tenant, (ii) the first installment and
second installment of Real Estate Taxes for Woodland VI for said fourth calendar
year of the Lease Term are paid by Landlord to the taxing authority on May 10
and November 10 of such year, respectively, in the amount of $40,000.00 per
installment, and (iii) $60,000.00 of Real Estate Taxes are abated for each such
installment (i.e., if not for the Tax Abatement, $100,000.00 of Real Estate
Taxes would have been payable by Landlord to the taxing authority for each
installment of Real Estate Taxes in said fourth year of the Lease Term). Based
on the forgoing, Landlord would pay to Tenant $30,000.00 on or before June 9 and
$30,000.00 on or before December 10 in said fourth year of the Lease Term, as
consideration for the tax savings to Landlord as a result of the Tax Abatement.
In the above example, Tenant would be responsible for $20,000.00 of each of said
installments based on its Building Expense Percentage of fifty percent (50%) for
Woodland VI, and any overpayment or underpayment by Tenant of its $40,000
obligation for Real Estate Taxes for said fourth calendar year of the Lease Term
would be considered in calculating the Annual Rental Adjustment following the
end of said fourth calendar year of the Lease Term. Notwithstanding the
forgoing, Tenant hereby agrees and acknowledges that Tenant shall be responsible
for Tenant’s pro-rata share of all Real Estate Taxes respecting Woodland VI
payable during the Lease Term based on Tenant's Building Expense Percentage for
Woodland VI. Tenant agrees to indemnify, defend and hold harmless Landlord from
and against any and all losses, claims or damages (including without limitation,
any abated Real Estate Taxes respecting Woodland VI which Landlord may be
required to reimburse to the taxing authority) resulting from Tenant's failure
to comply with its obligations under this Section or under any agreement entered
into by Tenant with the City of Indianapolis and/or other applicable
governmental authorities with respect to the Tax Abatement (collectively, the
"Tax Abatement Agreements").

-7-

--------------------------------------------------------------------------------

(b) Landlord agrees not to commence construction of Woodland VI prior to April
10, 2006. Immediately upon execution of this Lease, Tenant shall prepare and
file any required applications, forms, resolutions, agreements or other
materials, whether for or on behalf of Tenant or Landlord. To permit Tenant to
take the actions necessary to obtain and maintain property tax abatement
deductions on the Woodland VI, Landlord shall (i) upon reasonable notice from
Tenant, execute such tax abatement applications, forms, resolutions, agreements,
and other materials provided the same shall be in a form reasonably acceptable
to Landlord; (ii) upon reasonable notice from Tenant, provide Tenant with
information in its possession with respect to the Woodland VI necessary to
prepare such applications, forms, resolutions, agreements and other materials;
(iii) upon reasonable notice from Tenant, either appear or authorize Tenant to
appear on behalf of Landlord at any public hearing related to obtaining or
maintaining real estate tax abatement on the Woodland VI; and (iv) shall forward
to Tenant promptly upon receipt any notice of assessment or change in assessment
relating to the Woodland VI. Notwithstanding the forgoing in this Section 16.26,
Landlord shall not be required to enter into any agreement or take any other
action whereby Landlord would have any liability to the City of Indianapolis or
other applicable governmental authority under the Tax Abatement Agreements as a
result of Tenant's failure to comply with its obligations thereunder or
otherwise. This Section 16.26 shall survive the expiration or earlier
termination of the Lease.
 
Section 16.27. Termination Option. Provided that (a) no Default has occurred
which remains uncured, (b) Tenant originally named herein or a Permitted
Transferee remains in possession of and has been continuously operating (once
having taken possession of the applicable portion of the Additional Space as
provided in Section 2(b)B hereof) in the entire Additional Space from the First
Takedown Space Commencement Date through the effective date of the First
Termination Option or Second Termination Option, as applicable, (c) either (i)
all of Tenant's stock is acquired by an unaffiliated person or entity (an
"Unaffiliated Third Party") or (ii) substantially all of Tenant's assets are
acquired by an Unaffiliated Third Party, and (iv) neither Tenant, the
Unaffiliated Third Party or any affiliates thereof continue to have operations
(including the leasing or owning of any property for purposes of conducting
business) in Marion County, Indiana or any of the immediately surrounding
counties, Tenant shall have the right to terminate the Lease with respect to the
Additional Space and any other space leased in Woodland VI or Woodland I
effective as of either (1) the end of the fifth (5th) year of the Lease Term for
the Additional Space (the "First Termination Option"), or (2) the end of the
eighth (8th) year of the Lease Term for the Additional Space (the "Second
Termination Option"). For purposes of this Section 16.27, any officer or
director of Tenant or its affiliates shall be considered an affiliated party. In
order to exercise either such termination right, Tenant shall notify Landlord of
such exercise in writing at least twelve (12) months prior to the effective date
of such termination, and together with such notice, Tenant shall deliver to
Landlord, as an agreed upon termination fee, an amount equal to fifty percent
(50%) of the gross rent (i.e. all Minimum Annual Rent and Additional Rent) that
would have been paid by Tenant over the balance of the Lease Term for the
Additional Space and any other space leased by Tenant at Woodland VI and/or
Woodland I had Tenant not exercised its termination option. With respect to the
First Termination Option (assuming that Tenant does not exercise its option to
lease any of the Offer Space or otherwise lease additional space in Woodland VI
or Woodland I), Landlord estimates that the termination fee would be
approximately $4,520,975.75. With respect to the Second Termination Option
(assuming that Tenant does not exercise its option to lease any of the Offer
Space or otherwise lease any space in Woodland VI or Woodland I), Landlord
estimates that the termination fee would be approximately $1,808,390.30. Such
payment is made in consideration for Landlord's grant of the forgoing option to
terminate to compensate Landlord for rental and other concessions given to
Tenant and for other good and valuable consideration. The termination fee does
not constitute payment of rent to Landlord. If Tenant fails to notify Landlord
by the deadline set forth above, for the First Termination Option or the Second
Termination Option, as applicable, Tenant shall have waived the applicable
termination right for the remainder of the term of the Lease and any extensions
thereof."

26. Patriot Act. Each of Landlord and Tenant, each as to itself, hereby
represents its compliance with all applicable anti-money laundering laws,
including, without limitation, the USA Patriot Act, and the laws administered by
the United States Treasury Department's Office of Foreign Assets Control,
including, without limitation, Executive Order 13224 ("Executive Order"). Each
of Landlord and Tenant further represents (i) that it is not, and it is not
owned or controlled directly or indirectly by any person or entity, on the SDN
List published by the United States Treasury Department's Office of Foreign
Assets Control and (ii) that it is not a person otherwise identified by
government or legal authority as a person with whom a U.S. Person is prohibited
from transacting business. As of the date hereof, a list of such designations
and the text of the Executive Order are published under the internet website
address www.ustreas.gov/offices/enforcement/ofac.

27. Amendment of Section 6.01. Services to be Provided. Section 6.01 of the
Lease is hereby amended to provide that the second sentence thereof applies only
to Woodland V..

28. Broker. Tenant represents and warrants that, except for Meridian Real Estate
Services representing Tenant, no other real estate broker or brokers were
involved in the negotiation and execution of this Amendment on behalf of Tenant
and that Tenant is responsible for paying such broker. Landlord represents and
warrants that, except for Duke Realty Services, LLC representing Landlord, no
other real estate broker or brokers were involved in the negotiation and
execution of this Amendment on behalf of Landlord and that Landlord is
responsible for paying such broker. Each party shall indemnify the other and
hold it harmless from any and all liability for the breach of any such
representations and warrants on its part and shall pay any compensation to any
other broker or person who may be deemed or held to be entitled thereto as a
result of such indemnifying party's action.
