 2.3 Delivery of Expansion Spaces. Landlord shall deliver the Expansion Space to the Tenant
on May 1, 2007. As of the delivery date above, the definition of the term “Premises” shall include the Expansion Space, and the rentable square footage of the Premises shall be increased to 69,272. Tenant shall accept the Expansion
Space on an “as-is” basis with no further warranties or representations from the Landlord, except that Landlord warrants that, to its knowledge, the Expansion Space is free of hazardous materials. 
 2.4 Base Year and Base Taxes. 
 (a)
As of the Effective Date of this Amendment, the Base Operating Costs for the Existing Premises, Suite 210 and Suite 200 of the Expansion Space shall mean Operating Costs incurred for the 2007 calendar year. As of the Effective Date of this
Amendment, the Base Operating Costs for Suite 300 of the Expansion Space shall mean Operating Costs incurred for the 2000 calendar year. The 4% restriction on annual increases in Tenant’s Share of Operating Costs shall continue to apply to the
Premises, and as to Suite 300, shall be calculated from the 2000 calendar year as if Tenant had been subject to such increases in each subsequent year. If less than 95% of the rentable square feet in the Project is occupied by tenants or Landlord is
not supplying services to 95% of the rentable square feet of the Project at any time during any calendar year (including the Base Year), then Operating Costs for such calendar year shall be an amount equal to the Operating Costs which would normally
be expected to be incurred using reasonable projections and reasonable extrapolations from existing cost data had 95% of the Project’s rentable square feet been occupied and had Landlord been supplying services to 95% of the Project’s
rentable square feet throughout such calendar year. Furthermore, if after the Base Year, the Landlord provides additional services or incurs cost items in a category not otherwise covered in Operating Costs as defined herein, the Base Operating
Costs shall be increased in a manner as reasonably determined by Landlord to include such additional matter. 
 (b) As of the Effective Date
of this Amendment, Base Taxes for the Existing Premises, Suite 210 and Suite 200 of the Expansion Space shall mean Taxes incurred for the 

  

 3 

 
state fiscal tax year beginning July 1, 2007 and ending June 30, 2008. As of the Effective Date of this Amendment, Base Taxes for Suite 300 of the
Expansion Space shall mean Taxes incurred for the state fiscal tax year beginning July 1, 2000 and ending June 30, 2001. 
 2.5.
Renewal. 
 (a) Tenant shall have the option to renew the Term of this Lease for one (1) period of two (2) years (the
“Renewal Term”). Tenant shall exercise the option by providing written notice to Landlord of its election to exercise such option no later than twelve (12) months prior to the expiration of the Term (“Initial Notice
Period”), provided, however, that Tenant’s option to renew shall be subject to the condition that no default shall have occurred and be continuing after applicable notice and cure periods have expired as of the date of Tenant’s
exercise of such option or as of the date of commencement of the Renewal Term. Tenant shall have no other right to renew this Lease after the Renewal Term. Except as otherwise expressly provided in this Lease, all terms, covenants, and conditions of
this Lease shall remain in full force and effect during the Renewal Term, except that the Rent applicable to the Renewal Term shall be as set forth in this Section below. In no event shall the Rent for the Renewal Term be less than the Rent in
effect at the expiration of the immediately preceding Term of the Lease. If the Tenant fails to give notice exercising the foregoing option by the date required herein, or if at the time Tenant exercises such option or at commencement of the Renewal
Term the Tenant is in default beyond applicable notice and cure periods of any term of this Lease, or if this Lease is assigned by Tenant or the Premises is sublet in whole or part, then Tenant’s rights and options to renew shall be
automatically terminated and of no further force or effect. 
 (b) The Base Rent for the Renewal Term shall be the Market Rent as determined
in subsection (c) below. 
 (c) The “Market Rent” shall be the prevailing market rate of rent and all charges for
comparable space at the end of the Term as increased in accordance with market rate annual escalations. If Tenant exercises its option to renew hereunder, Tenant and Landlord shall make a good faith effort to agree on the Market Rent on or before a
date (the “Outside Negotiation Date”) which is no later than nine (9) months prior to the expiration of the Term, and prior to implementing the procedures set forth below if the parties are unable to agree. If Landlord and
Tenant are unable to agree upon the Market Rent by the Outside Negotiation Date, then Landlord and Tenant shall determine the Market Rent in accordance with the appraisal procedure set forth herein. Within ten (10) days after the Outside
Negotiation Date, the parties shall appoint a broker who shall be mutually agreeable to both Landlord and Tenant, shall have at least ten (10) years’ experience as a broker of commercial leasehold estates, and shall be knowledgeable in
office rentals in the Baltimore, Maryland market. If the parties are unable to agree on a broker within such ten (10) day period, then each party, within five (5) days after the expiration of such ten (10) day period, shall appoint a
broker (with the same qualifications) and the two (2) brokers (or the one broker if either Landlord or Tenant fails timely to appoint a broker) shall together appoint a third broker with the same qualifications. The broker or brokers so
appointed then shall determine, within sixty (60) days after the appointment of such broker or brokers, the then 

  

 4 

 
Market Rent for the Premises. Among the factors to be considered by the broker(s) in determining the fair market base rent for the Premises shall be those
factors set out below. The figure arrived at by the broker (or the average of the figures arrived at by the three brokers, if applicable) shall be used as the Market Rent for such renewal term. If the three broker method is chosen, then if any
broker’s estimate of fair Market Rent is either (x) less than ninety percent (90%) of the average figure or (y) more than one hundred ten percent (110%) of such average, then the fair market rent will be either (1) the
average of the remaining two (2) appraisal figures falling within such a range of percentages, (2) the remaining appraisal that is within such range of percentages or (3) if none of the figures are within such range, the average of
the three (3) appraisals. Landlord and Tenant shall each bear the cost of its broker and shall share equally the cost of the third broker. 
 (d) In determining the Market Rent, the parties hereto and such brokers shall be guided by the following principles: the Market Rent shall be determined by reference to newly finished built-out office space in office buildings in Baltimore,
Maryland or neighborhoods in the Baltimore, Maryland metropolitan area most comparable to the quality, location, amenities, stature, reputation, visibility and services of the Building. The Market Rent shall take into account the fact that there are
no new tenant improvements to be constructed by Landlord nor other lease-up costs (except broker commissions, if any) and shall provide for updating the Base Operating Costs to the first year of each renewal term, if such factors are considered
market concessions at such time. The valuation shall be conducted in accordance with the provisions of this Section and, to the extent not inconsistent herewith, in accordance with the then prevailing rules of the American Arbitration Association in
Maryland (or any successor thereto). The final determination of such brokers shall be in writing and shall be binding and conclusive on the parties, each of whom shall receive counterpart copies thereof. In rendering such decision the brokers shall
not add to, subtract from, or otherwise modify the provisions of this Lease. In determining the Market Rent, the brokers shall consider all the items set forth above for consideration in determining the Market Rent. Instructions to such effect shall
be given to the brokers. 
 (e) Notwithstanding the above, Tenant will have the right to rescind its renewal option at any time within ten
(10) calendar days after a final written determination is made of the Market Rent in accordance with the above procedures. 
 2.6.
Parking. In addition to the rights to parking spaces under the Existing Lease, Tenant shall have the non-exclusive right to use 58 additional on-site parking spaces. At Landlord’s request, Tenant shall provide license plate numbers for
its employees and otherwise cooperate with Landlord’s management of the Parking Areas, which may include attended parking service. Tenant shall not obligated to pay any Additional Rent for any such parking spaces. 
  

 5 

 2.7. Limited Right of Termination. 
 (a) Tenant shall have a conditional right to terminate this Lease effective [***] (the “Early Termination Date”). If Tenant exercises
its right hereunder, it shall give the Landlord written notice of its election to terminate (the “Termination Notice”) at least [***] months prior to the Early Termination Date (the “Termination Period”).

 (b) [***] 
 (c) [***]

 (d) If, and only if, Tenant delivers the Termination Notice within the Termination Period, and Tenant pays to Landlord the Termination
Fee, if required, and further provided that Tenant is not in default of any term of this Lease beyond any applicable notice and cure period either on the date of the Termination Notice or on the Early Termination Date, then the Lease will terminate
effective on the Early Termination Date. 
 2.8. Assignment and Subletting. The provisions of Section 14 of the Existing Lease
will continue to apply to any assignment or subletting of the Premises, however no consent from Landlord will be required for an assignment or subletting of all or any portion of the Premises so long as Tenant remains obligated on the Lease and the
percentage of profit that is payable for Landlord in accordance with Section 14.4 would increase to one hundred percent. 
 3.
Survival and Conflict. The Lease shall remain in full force and effect, fully binding on Landlord and Tenant and unmodified except as expressly provided herein. In the event of any conflict between the terms of the Lease and the terms of this
Amendment, the terms of this Amendment shall govern.

 IN WITNESS WHEREOF, Landlord and Tenant have duly executed this Amendment on the date written first
above.
