Notwithstanding any provision of the Lease (as amended by this First Amendment)
to the contrary, but subject to the condition that Tenant is not in default in
the payment of any Rental under the Lease which remains uncured after any
applicable notice and/or grace period has expired, Landlord hereby releases
Tenant from the obligation to pay its Monthly Basic Rent for the period from
March 1, 2014 through June 30, 2014 in the total amount of $82,310.16; for the
period from July 1, 2015 through July 31, 2015 in the amount of $20,909.44; for
the period from July 1, 2016 through July 31, 2016 in the amount of $21,241.33;
for the period from July 1, 2017 through July 31, 2017 in the amount of
$21,573.23; for the period from July 1, 2018 through July 31, 2018 in the amount
of $21,905.13; and for the period from July 1, 2019 through July 31, 2019 in the
amount of $22,237.02; provided, however, that in the event that Tenant defaults
in the payment of any Rental under the Lease during or subsequent to said free
rent periods, which default remains uncured after any applicable notice and/or
grace period has expired, then the amount of Monthly Basic Rent which Tenant was
released from the obligation to pay during the said free rent periods shall
become due and payable as additional rent hereunder within five (5) days of
demand by Landlord. During the free rent periods, Tenant shall remain obligated
to pay Landlord all charges, other than Monthly Basic Rent, payable pursuant to
the Lease.

6. Discretionary Allowance. Landlord agrees to provide Tenant an amount not to
exceed Eighty Five Thousand Dollars ($85,000.00) (the “Discretionary Allowance”)
for the purchase, installation and/or construction (including, without
limitation, any soft costs such as permits and architect’s fees) of a Liebert
unit servicing Tenant’s computer room and such other improvements, equipment
(including, without limitation, movable equipment), furniture (including,
without limitation, movable furniture), fixtures and finishes for the Premises
desired by Tenant and refurbishing of existing furniture (“Tenant’s Work”).
Landlord agrees that to the extent Tenant’s Work includes any equipment or
furniture that is not affixed to the Leased Premises, that such equipment or
furniture shall remain Tenant’s property notwithstanding anything in the Lease
(as amended hereby) to the contrary. Any portion of Tenant’s Work consisting of
improvements to the Premises must be approved by Landlord in advance, shall be
bid, paid for by Landlord and supervised by Landlord and shall be performed in
accordance with the Lease; provided the Landlord will provide Tenant three
(3) competitive bids with Tenant to select the approved bid. Landlord shall pay
Tenant that portion of the Discretionary Allowance Tenant utilizes for equipment
or furniture within ten (10) days after receipt of paid invoices therefore. For
the avoidance of doubt, the Liebert unit and related installation costs are
deemed to be equipment and not improvements to the Premises. The Discretionary
Allowance must be utilized after the date of this First Amendment, but prior to
July 1, 2017. Any portion of the Discretionary Allowance for which Tenant has
not submitted to Landlord a request for reimbursement on or before July 1, 2017
shall be forfeited by Tenant. The cost of any Tenant’s Work exceeding the
Discretionary Allowance shall be Tenant’s responsibility. All of Tenant’s
contractors who perform work on the Premises must be insured pursuant to the
terms of the Lease and are subject to Landlord’s approval.

7. Option to Terminate. Tenant acknowledges that its Option to Terminate the
Lease, as provided in Section 18.17, has expired.

8. Notices. Landlord’s address set forth in Section 17.01 of the Lease is hereby

9. Parking. Section 18.13 of the Lease is hereby deleted in its entirety and
replaced with the following:

SECTION 18.13. PARKING. Landlord shall provide to Tenant, at Landlord’s expense
and on the terms and conditions set forth herein, twenty seven (27) parking
spaces in the lower level of the garage beneath the Building and twenty
(20) parking spaces located at 401 and 415 North New Jersey Street (the “415
Lot”) for the Extension Term of the Lease (the “Parking Spaces”). The 415 Lot is
referred to herein as the “Parking Areas”.

(a) Tenant shall cause each employee of Tenant who will use a Parking Space to
complete and sign the Parking Agreement attached hereto as Exhibit A and
incorporated herein. Tenant agrees and acknowledges that neither Tenant nor its
employees shall use those parking spaces (i) designated for use by other tenants
or (ii) designated for use of by retail customers of the Project (the “Parking
Covenants”).

(b) In the event Tenant or any of its employees violate the Parking Covenants,
Landlord shall have the rights set forth below, including without limitation the
right to tow or cause any such vehicles to be towed at Tenant’s expense, and the
right to exercise any and all other remedies at law or in equity. Upon the first
violation of the Parking Covenants by Tenant or any of its employees, Tenant
shall reimburse Landlord for any towing expense incurred by Landlord. Upon the
second violation of the Parking Covenants by any employee of Tenant, in addition
to reimbursing Landlord for any towing expense, at Landlord’s option, such
employee’s rights to use any of the Parking Spaces shall terminate. Upon the
third and each subsequent violation of the Parking Covenants by Tenant or any of
its employees, in addition to reimbursing Landlord for any towing expense,
Tenant shall pay Landlord a fine in the amount of $500. The towing expenses and
any fines shall be due Landlord as Additional Rent within five (5) days of
demand.

(c) Notwithstanding the foregoing, under no circumstances shall Landlord have
the obligation to patrol the Parking Areas or enforce Tenant’s right to use the
Parking Spaces. Tenant and its employees, agents, contractors, invitees and
licensees shall use the Parking Areas at their own risk and Landlord shall not
be responsible for, and Tenant, for itself and on behalf of such parties, hereby
releases Landlord from and against any loss, damage or injury relating to
Tenant’s or such parties’ use of the Parking Areas.

(d) The parties agree that Tenant’s use of the Parking Area shall be solely for
vehicle parking and for no other purpose. The rights granted to Tenant in this
Section are personal to Tenant and shall expire upon any assignment of the Lease
or subletting of all or a portion of the Leased Premises.

( e) The provisions of paragraph (b) above are not applicable in the event a
Parking Covenant violation occurs because Tenant, or any of its employees, are
prevented from accessing or utilizing their respective designated parking space,
as long as Tenant calls Property Management as soon as reasonably possible to
notify them of the parking situation, and Tenant follows Property Management’s
instructions for resolution.

10. Broker. Each party represents and warrants to the other party that it has
dealt with no broker, finder or other person other than Jones Lang LaSalle with
respect to Tenant and Cassidy Turley with respect to Landlord (collectively,
“Broker”) in connection with the transaction contemplated hereby. Landlord shall
be solely responsible for paying the commission of Broker pursuant to the terms
of a separate agreement between Landlord and Broker. Each party shall indemnify
and hold harmless the other party against any loss, liability, damage or claim
incurred by reason of any commission or fee alleged to be payable to anyone
other than the Broker because of any act, omission or statement of the
indemnifying party. Such indemnity obligation shall be deemed to include payment
of reasonable attorneys’ fees and court costs incurred in defending any such
claim.

11. Confidentiality. Excluding the Securities and Exchange Commission and other
regulatory filings to which Tenant is subject, any and all information regarding
the terms and provisions of this First Amendment, (herein, the “Confidential
Information”), shall be maintained by Landlord and Tenant and each of Landlord
and Tenant’s employees, agents, principals, and representatives in strict
confidence, and shall not be disclosed to third parties including, but not
limited to, other tenants or occupants of the Project, without the prior written
consent of the other. The parties hereto acknowledge and agree that any breach
of this confidentiality provision would cause irreparable harm to the other
which may not be adequately remedied by monetary damages and that, as a result,
the non-disclosing party may, in such event, in addition to any other rights or
remedies available hereunder or at law or in equity, seek an injunction
enjoining any disclosure of the Confidential Information. This obligation of
confidentiality shall not apply to disclosures compelled by law, any order of a
court of competent jurisdiction or by a lawful, proper subpoena, in which event
the disclosing party shall immediately notify the non-disclosing party of the
circumstances purporting to require such disclosure and shall refrain from such
disclosure for the maximum period of time allowed by law so that the
non-disclosing party may take such actions as it may deem appropriate to protect
the Confidential Information being sought. The parties shall use commercially
reasonable efforts to make all parties having access to the Confidential
Information aware of their obligation of confidentiality described in the
paragraph and shall bind such parties to similar obligations of confidentiality.
The terms of this paragraph shall expressly survive the expiration or earlier
termination of this First Amendment for the longest period provided by law.

12. Governing Law. This First Amendment shall be governed by and subject to the
laws of the State of Indiana.

13. Counterparts. This First Amendment may be executed in separate counterparts,
each of which when so executed shall be an original, but all of such
counterparts shall together constitute one and the same instrument. Signatures
of this First Amendment which are transmitted by either or both electronic and
telephonic means (including, without limitation, facsimile and email) are valid
for all purposes. Any party shall, however, deliver an original signature of
this First Amendment to the other party upon request.

14. Ratification. Except as amended by this First Amendment, all of the terms
and conditions of the Lease shall remain in full force and effect. In the event
of any conflict between the terms and conditions contained in this First
Amendment and the terms and conditions contained in the Lease, the terms and
conditions of this First Amendment shall control. The parties hereto acknowledge
and agree that neither party is currently in default of the Lease.

15. Miscellaneous. This First Amendment is binding on the parties and their
respective successors and assigns. Tenant shall not record this First Amendment
or a memorandum thereof. If any provision of the Lease, as amended by this First
Amendment, is held by the final judgment of any court of competent jurisdiction
to be illegal, invalid or unenforceable, the validity of the remaining portions
or provisions must not be impaired or affected, and the rights and obligations
of the parties must be construed and enforced as if the Lease, as amended by
this First Amendment, did not contain that certain part, term or provision held
to be illegal, invalid or unenforceable. The Lease, as amended by this First
Amendment, constitutes the entire agreement between Landlord and Tenant with
respect to the Premises and may be amended or altered only by written agreement
executed by both parties, and supersedes all prior agreements, whether written
or oral, between the parties. Landlord represents that it is not required to
obtain the consent of any one or more third parties (including, without
limitation, any one or more parties holding mortgages, deeds of trusts or
similar security interests in the Premises) in connection with this First
Amendment. Landlord and Tenant each represent and warrant to the other party:
(a) the execution, delivery and performance of this First Amendment have been
duly approved by such party and no further action is required on the part of
such party to execute, deliver and perform this First Amendment; (b) the
person(s) executing this First Amendment on behalf of such party have all
requisite authority to execute and deliver this First Amendment; and (c) this
First Amendment, as executed and delivered by such person(s), is valid, legal
and binding on such party, and is enforceable against such party in accordance
with its terms.

IN WITNESS WHEREOF, the parties have executed this First Amendment as of the day
and year first written above.
