The period

1

beginning on the Extension Date and continuing through the Revised Lease Expiration Date is the “Extension Term” and the Summary of Basic Lease Information and Section 3 of the Lease are amended accordingly.

b. Monthly Base Rent for Extension Term. The monthly Base Rent for the Original Premises for the Extension Term is as follows, and the Summary of Basic Lease Information of the Lease is amended accordingly:

c. Expanded Premises. Effective as of the later to occur of the following: (a) December 1, 2012; or (b) provided that Tenant takes possession by December 21, 2012, the date on which Tenant takes possession of the Temporary Expansion Space, as defined below (the “Initial Effective Date”), the Original Premises (as described in Section A of Part I of the Lease) shall be temporarily increased by approximately 3,547 square feet of Rentable Area (3,085 usable square feet) on the third (3^rd) floor of the Building known as Suite 360 (the “Temporary Expansion Space”), so that the increased Premises temporarily totals approximately 26,869 square feet of Rentable Area (23,316 usable square feet). The location of the Temporary Expansion Space is shown on the Floor Plan attached as Exhibit “A” to this Addendum No. 5. Tenant’s right to occupy the Temporary Expansion Space pursuant to the terms and conditions of the Lease shall expire as of June 30, 2013 (the “Temporary Expansion Space Termination Date”).

Except as provided in Section 4 below, Tenant hereby accepts the Expanded Premises in their current “AS-IS” condition, without any additional modification, improvement or refurbishing by Landlord. The description of the Original Premises contained in Section A of Part I of the Lease is amended accordingly. Notwithstanding the above, the increase in the Rentable Area to include the Temporary Expansion Space and the Second Expansion Space is expressly contingent upon the termination of the lease for the current occupant of the Temporary Expansion Space and the Second Expansion Space, respectively (the “Prior Leases”). Landlord shall not be liable for a delay in Tenant’s occupancy of the Temporary Expansion Space or the Second Expansion Space, as applicable, due to Landlord’s inability to terminate the Prior Leases and to deliver possession of the Temporary Expansion Space and the Second Expansion Space by the dates set forth above. The Landlord shall not be subject to any liability, including,

2

without limitation, lost profits or incidental or consequential damages for any delay or inability to deliver possession of the Temporary Expansion Space or the Second Expansion Space, as applicable, to the Tenant. In the event that Landlord is unable to deliver possession of the Temporary Expansion Space by the date set forth above, Tenant shall not be liable or obligated to take possession of the Temporary Expansion Space, or make any Monthly Base Rent payments to Landlord in excess those set forth in Section 3(b) above. If Landlord is able to deliver possession of the Temporary Expansion Space by the date set forth above but is unable to deliver possession of the Second Expansion Space by the date set forth above, Landlord shall extend the Temporary Expansion Space Termination Date to allow Tenant to take possession of the Second Expansion Space or continue possession of the Temporary Expansion Space through a mutually agreed upon date. For each month that Tenant’s possession of the Second Expansion Space is delayed due to Landlord’s inability to deliver possession, the Monthly Base Rent for the Second Expansion Space shall be reduced to an amount equivalent to the Monthly Base Rent of the Temporary Expansion Space for a corresponding number of months.

d. Base Rent for Temporary Expansion Space and Second Expansion Space. From and after the Initial Effective Date through the Temporary Expansion Space Termination Date, Section C of Part I of the Lease is hereby amended to include the Base Rent for the Temporary Expansion Space as follows:

i. Base Rent (Lease Provisions, Paragraph 5):

i. Remove the existing wall located between the receptionist area and the mail area and patch and paint the walls and patch the carpet to match the existing paint and carpet in the Temporary Expansion Space.

i. Construct a full-height demising wall, separating the Second Expansion Space from the adjacent space at the Building (the “Demising Wall”). The Demising Wall will be constructed according to Landlord’s building standard specifications. In conjunction with the construction of the Demising Wall, Landlord shall make any required modification of the Building’s electrical, mechanical, plumbing, HVAC or other systems as necessary to service the newly demised area.

ii. Convert the existing mail room into a kitchen. Landlord will install a sink and use the existing cabinets and shelves. Landlord will install electrical to the kitchen (if not already available), to accommodate a microwave and small refrigerator. Any appliances for the kitchen shall be at Tenant’s sole cost and expense.

5. Lease Extension. Subject to the provisions of the Lease, Landlord hereby grants to Tenant the option (“Extension Option”) to extend the term of the Lease for one (1) extension term of up to five (5) years in accordance with the provisions set forth in this Section 5 (the “Extension Renewal Term”). If the Term of the Lease is so extended, the extension shall be on the same terms and conditions as are applicable during the initial Term, as extended by this Addendum No. 5, except that the Base Rent during the Extension Renewal Term shall be at the “Prevailing Rental Rate” which shall mean the rental rate determined for the most comparable office space located in the Building as of the date of the Extension Notice (defined below) and taking into account all relevant factors including, without limitation, any applicable tenant improvement allowance, Base Year and expense then in effect, but in no event less than the Rent under the Lease as of the date of the Extension Notice. If Tenant desires to exercise the Extension Option, it shall send notice thereof (the “Extension Notice”) to Landlord no more than three hundred (300) nor less than two hundred seventy (270) calendar days prior to the expiration of the Extension Term. Landlord and Tenant shall endeavor in good faith to determine the Prevailing Rental Rate within thirty (30) calendar days after Landlord’s receipt of Tenant’s Extension Notice. If they cannot agree within thirty (30) calendar days, each shall appoint an appraiser who shall arrive at an estimate of the Prevailing Rental Rate within thirty (30) calendar days. If such estimates are within five percent (5%) of each other, the average of the two shall

5

be the new Base Rent for the Extension Renewal Term. If the estimates are more than five percent (5%) apart, each appraiser shall select a third appraiser within five (5) calendar days or, if they fail to do so, Landlord shall select a third appraiser. The third appraiser shall prepare an estimate of the Prevailing Rental Rate as provided above within thirty (30) calendar days and the two closest of the three estimates shall be averaged to determine the new Base Rent for the Extension Renewal Term. No later than one hundred fifty (150) calendar days prior to the expiration of the Extension Term, Landlord and Tenant shall execute an amendment to the Lease (the “Extension Amendment”) stating the new Base Rent and expiration date of the Lease Term. If such an Extension Amendment is not fully executed for any reason as provided above, the Term shall not be extended and the Extension Option hereunder shall terminate. Notwithstanding the foregoing, Tenant shall not be entitled to extend this Lease if an uncured Event of Default has occurred under any term or provision contained in the Lease Agreement or a condition exists which with the passage of time or the giving of notice, or both, would constitute an Event of Default pursuant to the Lease Agreement as of the date of exercise of this Extension Option. The rights contained in this Section 5 shall be personal to the originally named Tenant and may be exercised only by the originally named Tenant and any Related Entity (and not any other assignee, sublessee or other Transferee of Tenant’s interest in this Lease) and only if the originally named Tenant or Related Entity occupies the entire Premises as of the date it exercises the Extension Option in accordance with the terms of this Section 5. If Tenant properly exercises the Extension Option and is not in default under this Lease at the end of the Extension Term, as it applies to the entire Premises then leased by Tenant, shall be extended for the Extension Renewal Term and the Base Year shall be included among the factors considered in determining the Prevailing Rental Rate. If Tenant fails to deliver a timely Extension Notice, Tenant shall be considered to have elected not to exercise the Extension Option. Any termination of the Lease during the Extension Term shall terminate all renewal or lease extension rights hereunder. The extension rights of Tenant hereunder shall not be severable from the Lease, nor may such rights be assigned or otherwise conveyed in connection with any permitted assignment of the Lease. During the Extension Renewal Term (a) no rent abatement or other concession, if any, applicable to the initial Lease Term or Extension Term shall apply to the Extension Renewal Term, and (b) all leasehold improvements within the Expanded Premises shall be provided in their then-existing condition (on an “as-is” basis) at the time the Extension Renewal Term commences.

6. Right of First Offer. Subject to the existing rights of any other tenant in the Building, Landlord shall notify Tenant that additional office space (the “Additional Space”) is to become vacant and available in the Building together with the terms on which Landlord desires to lease such space (the “Offer Terms”). Tenant may, by written notice to Landlord within three (3) business days after receipt of Landlord’s notice together with the Offer Terms, accept Landlord’s offer to lease the Additional Space upon the Offer Terms. Rent for the Additional Space shall become due and payable on the date Landlord delivers the Additional Space to Tenant free of other tenants and occupants and otherwise in accordance with the Offer Terms. Promptly after Tenant accepts this offer but no later than five (5) business days after Tenant’s notice to Landlord of its acceptance of such offer, the parties shall enter into an amendment to this Lease setting forth the terms and conditions upon which Tenant shall lease the Additional Space and incorporating the Additional Space as part of the Expanded Premises. The rights of Tenant under this Section are personal to the original Tenant named herein and may not be

6

exercised by any sublessee or assignee, or by any other successor or assign of Tenant. Tenant’s rights under this Section 6 shall be effective only if (i) Tenant has not sublet any portion of the Expanded Premises and is then actually occupying no less than one hundred percent (100%) of the Expanded Premises, and (ii) Tenant is not in Default under this Lease, nor has any event occurred which with the giving of notice or the passage of time, or both, would constitute a Default hereunder, either at the time of Landlord’s presentation of the Offer Terms or the time of Tenant’s acceptance of Landlord’s offer as set forth above.

7. Broker. Landlord and Tenant each represent to the other that it has had no dealings with any real estate broker, agent or finder in connection with the negotiation of this Addendum No. 5, except for Janet G. West of Sage Realty Services, L.C. (“Broker”), and that they know of no other real estate broker, agent or finder who is entitled to a commission or finder’s fee in connection with this Addendum No. 5. Each party shall indemnify, protect, defend and hold harmless the other party against all claims, demands, losses, liabilities, lawsuits, judgments, and costs and expenses (including reasonable attorney fees) for any leasing commission, finder’s fee, equivalent compensation alleged to be owing on account of the indemnifying parties’ dealings with any real estate broker, agent or finder other than the Broker.
