 WHEREAS, Tenant desires to lease additional premises from Landlord, to wit, the First Amendment
Additional Premises; 
 WHEREAS, Landlord is willing to lease the First Amendment Additional Premises to Tenant upon the terms and conditions
hereinafter set forth; 
 NOW THEREFORE, the above-described lease (the “Lease”) is hereby amended as follows: 
 1. DEMISE OF THE FIRST AMENDMENT ADDITIONAL PREMISES 
 Landlord hereby demises and leases to Tenant and Tenant hereby hires and takes from Landlord, the First Amendment Additional Premises. Said demise of the First Amendment Additional Premises shall be for a term
commencing as of the First Amendment Additional Premises Lease Commencement Date, as hereinafter defined, and expiring as of February 28, 2013, and shall be upon all of the terms and conditions of the Lease (including, without limitation,
Tenant’s renewal options set forth in Section 38 of the Lease), except as follows: 
 A. The First Amendment Additional Premises
Lease Commencement Date is estimated to be May 1, 2007. If Landlord is delayed delivering possession of the First Amendment Additional Premises due to the holdover or unlawful possession of the First Amendment Additional Premises by the current
tenant of the First Amendment Additional Premises, Landlord shall use reasonable efforts to obtain possession of the First Amendment Premises, and the First Amendment Additional Premises Lease Commencement Date shall be delayed until the date
Landlord delivers possession of the First Amendment Additional Premises to Tenant free from occupancy by the current tenant of the First Amendment Additional Premises. 
 B. Notwithstanding the foregoing, if the First Amendment Additional Premises Lease Commencement Date shall not have occurred on or before the Outside Date, as hereinafter defined, then Tenant shall have the right,
exercisable by a written thirty (30) day termination notice given on or after the Outside Date, to terminate its leasing of the First Amendment Additional Premises. If the First Amendment Additional Premises Lease Commencement Date occurs on or
before the thirtieth (30th) day after Landlord receives such termination notice, Tenant’s termination notice shall be deemed to be void and of no force or effect. If the First Amendment Additional Premises Lease Commencement Date does not
occur on or before such thirtieth (30th) day, the Lease in respect of the First Amendment Additional Premises only shall terminate and shall be of no further force or effect, but the Lease shall remain in full force and effect with respect to
the remainder of the premises. For the purposes hereof, the “Outside Date” shall be defined as October 1, 2007. 
 C. The rent
commencement date in respect of the First Amendment Additional Premises (“First Amendment Additional Premises Rent Commencement Date”) shall be the date which is ninety (90) days after the First Amendment Additional Premises Lease
Commencement Date.

 3. LANDLORD’S CONTRIBUTION IN RESPECT OF THE FIRST AMENDMENT ADDITIONAL PREMISES 

A. Landlord shall, in the manner hereinafter set forth, contribute up to One Hundred Fifty Thousand Two Hundred Two and 00/100 Dollars ($150,202.00)
(“Landlord’s Contribution”) towards the cost of leasehold improvements to be installed by Tenant in the First Amendment Additional Premises (“Tenant’s Work”). Tenant’s Work shall be performed in accordance with the
Lease including, without limitation, Section 8 thereof. 
 B. Provided that Tenant is not in default of its obligations under the Lease
at the time that Tenant submits any requisition on account of Landlord’s Contribution, Landlord shall reimburse Tenant for the cost of the work shown on each requisition (as hereinafter defined) submitted by Tenant to Landlord within thirty
(30) days of submission thereof by Tenant to Landlord. For the purposes hereof, a “requisition” shall mean written documentation from Tenant’s contractor showing in reasonable detail the costs of the improvements then installed
by Tenant in the First Amendment Additional Premises. Each requisition shall be accompanied by evidence reasonably satisfactory to Landlord that all work covered by such requisition has been fully paid by Tenant. Tenant shall submit requisition(s)
no more often than monthly. 
 C. Notwithstanding anything to the contrary herein contained: 
 (i) Landlord shall have no obligation to advance funds on account of Landlord’s Contribution unless and until Landlord has received the requisition
in question, together with certifications from Tenant’s architect, certifying that the work shown on the requisition has been performed in accordance with applicable law and in accordance with Tenant’s approved plans. 
 (ii) Landlord shall have no obligation to pay Landlord’s Contribution in respect of any requisition submitted after the date which is eighteen
(18) months after the First Amendment Additional Premises Lease Commencement Date (the “Final Requisition Date”). 
 (iii)
Tenant shall not be entitled to any unused portion of Landlord’s Contribution. Notwithstanding the foregoing, after the Final Requisition Date, provided Tenant has occupied the First Amendment Additional Premises for its business
purposes, Tenant shall be entitled to apply up to $35,000.00 of any unused portion of Landlord’s Contribution towards Tenant’s next installment of Base Rent. 
  

 -4- 








 D. Except for Landlord’s Contribution, Tenant shall bear all other costs of Tenant’s Work.
Landlord shall have no liability or responsibility for any claim, injury or damage alleged to have been caused by the particular materials, whether building standard or non-building standard, selected by Tenant in connection with Tenant’s Work.

 4. SECURITY DEPOSIT 
 Tenant shall, on the First Amendment Additional Premises Lease Commencement Date, pay to Landlord a security deposit of Forty Thousand Six Hundred Two and 68/100 Dollars ($40,602.68) securing Tenant’s obligations under the Lease. In no
event shall said security deposit be deemed to be a prepayment of rent nor shall it be considered a measure of liquidated damages. Tenant agrees that no interest shall accrue on said deposit and that Landlord shall have no obligation to maintain
such deposit in a separate account (i.e. Landlord shall have the right to commingle such deposit with other funds of Landlord). In the event that Tenant shall default in any of its obligations under the Lease, Landlord shall have the right, without
prior notice to Tenant, to apply said deposit (or any portion thereof) towards the cure of any such default and Tenant shall promptly, upon notice from Landlord, pay to Landlord any amount so applied by Landlord in order to restore the full amount
of said deposit. In addition, in the event of a termination based upon the default of Tenant under the Lease, or a rejection of the Lease pursuant to the provisions of the Federal Bankruptcy Code, Landlord shall have the right to apply said security
deposit (from time to time, if necessary) to cover the full amount of damages and other amounts due from Tenant to Landlord under the Lease. Any amounts so applied shall, at Landlord’s election, be applied first to any unpaid rent and other
charges which were due prior to the filing of the petition for protection under the Federal Bankruptcy Code. The application of all or any part of the deposit to any obligation or default of Tenant under the Lease shall not deprive Landlord of any
other rights or remedies Landlord may have nor shall such application by Landlord constitute a waiver by Landlord. Provided that Tenant is not in default of any of its obligations under the Lease at the expiration of the Term of the Lease, Landlord
shall refund to Tenant any portion of said security deposit which Landlord is then holding within sixty (60) days after the expiration of the Term of the Lease. 
 5. PARKING 
 The parties hereby acknowledge that, pursuant to Section 34 of the Lease, Tenant has
the right to purchase sixty-three (63) unreserved Parking Permits in the garage of the Building, five (5) of which unreserved Parking Permits shall be at no charge to Tenant throughout the Term of the Lease. The parties hereby further
acknowledge that, with respect to the First Amendment Additional Premises, Tenant has the right to purchase an additional fifteen (15) unreserved Parking Permits (“Additional Parking Permits”) in the garage of the Building. The
current monthly rate for such Additional Parking Permits is One Hundred Forty and 00/100 Dollars ($140.00) per month per unreserved permit, subject to change from time to time upon reasonable prior notice (which may be by posting such change in the
garage or such other means as the operator of the garage 

  

 -5- 








 
deems appropriate). The use of said Additional Parking Permits shall be upon all of the same terms and conditions set forth in said Section 34 of the
Lease, except that: (i) Tenant shall not be entitled to use any of the Additional Parking Permits as reserved Parking Permits, (ii) none of the Additional Parking Permits shall be free to Tenant, and (iii) Landlord shall not have the
right to allocate any of the Additional Parking Permits to the 1101 Wilson Boulevard parking garage. 
 6. BROKER 
 Landlord and Tenant each represents and warrants to the other that, except as hereinafter set forth, neither of them has employed any broker in procuring
or carrying on any negotiations relating to this First Amendment. Landlord and Tenant shall indemnify and hold each other harmless from any loss, claim or damage relating to the breach of the foregoing representation and warranty. Landlord
recognizes only Monday Properties, as Landlord’s Broker, and only The Staubach Company — Northeast, Inc., as Tenant’s Broker, as brokers with respect to this First Amendment. Landlord agrees to be responsible for the payment of any
leasing commissions owed to Landlord’s Broker, and Landlord’s Broker agrees to be responsible for the payment of any leasing commissions owed to Tenant’s Broker, pursuant to a separate agreement between Landlord’s Broker and
Tenant’s Broker.

Premises as of the date of this First Amendment have lapsed unexercised or have been waived, and (iii) Landlord intends to offer such area for lease). In no event shall Tenant have any rights under this Paragraph 6 on or after the date
twelve (12) months prior to the Lease Expiration Date (i.e. Landlord shall have no obligation to give Landlord’s Notice, as hereinafter defined, to Tenant on or after the date twelve (12) months prior to the Lease Expiration Date).

 (3) Condition of RFO Premises 
 Tenant shall take the RFO Premises “as-is” in its then (i.e. as of the date of premises delivery) state of construction, finish, and decoration,

to the Lease without the need for any further documentation, as aforesaid, the parties hereby agree promptly to execute a lease amendment reflecting the addition of the RFO Premises. The execution of such lease amendment shall not be deemed to waive
any of the conditions to Tenant’s exercise of the herein option to lease the RFO Premises, unless otherwise specifically provided in such lease amendment. 
 E. Notwithstanding anything to the contrary herein contained, Tenant’s rights to lease any RFO Premises under this Paragraph 6 shall be subject and subordinate to the rights (whether expansion rights, rights of
first refusal and/or rights of first offer) of any tenant of the Building existing on the Execution Date of this First Amendment. 
 9.
INAPPLICABLE AND DELETED LEASE PROVISIONS 
 A. Sections 1(S) and (T) of the Lease, Sections 3 and 43 of the Lease and Exhibit C
to the Lease shall have no applicability in respect of the First Amendment Additional Premises.
