RECITALS

A. Landlord and Tenant entered into a certain Office Lease, dated as of June 15, 2012 (the “Original Lease”) as amended by a First Amendment to Lease, dated as of October 23, 2012 (“First Amendment”), a Second Amendment to Lease dated as of November 5, 2013 (the “Second Amendment”), a Third Amendment to Lease dated as of March 10, 2014 (the “Third Amendment), a Temporary Space Extension Agreement dated as of May 1, 2014, a Fourth Amendment to Lease dated as of May 21, 2014 (the “Fourth Amendment”), and a Fifth Amendment to Lease dated as of June 26, 2014 (the “Fifth Amendment”) (the Original Lease as so amended, is referred to herein as the “Lease”).

B. Pursuant to the terms and conditions of the Fourth Amendment, Landlord is required to deliver to Tenant the Second Expansion Premises. Landlord has not yet delivered the Second Expansion Premises to Tenant, and Landlord and Tenant desire to modify Landlord’s delivery requirements and confirm the timing for delivery of the Second Expansion Premises to Tenant, subject to and as provided in this Amendment.

C. Accordingly, the parties desire to amend the Lease as set forth in and subject to the terms and conditions contained in this Amendment.

NOW, THEREFORE, in consideration of these premises and other good and valuable consideration, the receipt and legal sufficiency of which are hereby acknowledged, the parties agree as follows:

1. Capitalized Terms. All capitalized terms which are not specifically defined in this Amendment and which are defined in the Lease will have the same meaning for purposes of this Amendment as they have in the Lease.

2. Second Expansion Premises. Sections 3(a), 3(b) and 3(c) of the Fourth Amendment are hereby deleted and replaced with the following:

“(a) Subject to the provisions of this Section 3, effective as of the Second Expansion Effective Date (as defined below), Landlord leases to Tenant, and Tenant leases from Landlord, the Second Expansion Premises. Landlord shall deliver the Second Expansion Premises to Tenant in the Improvable Condition (as defined below) on June 1, 2016 or as soon thereafter as Landlord is reasonably able to do so. The Second Expansion Premises will be in “Improvable Condition” when in “broom clean” condition and all tenants have been relocated from the Second Expansion Premises or have otherwise vacated the Second Expansion Premises and Landlord has exclusive possession of the Second Expansion Premises. Landlord shall use good faith, diligent efforts (at

1 – SIXTH AMENDMENT TO LEASE

Landlord’s sole cost and expense) to deliver the Second Expansion Premises on June 1, 2016. If Landlord fails to deliver possession of the Second Expansion Premises to Tenant in the Improvable Condition on or prior to November 30, 2016, Tenant shall be entitled to send written notice to Landlord stating that if Landlord has not delivered the Second Expansion Premises within thirty (30) days after the date of Tenant’s notice, Tenant may elect to terminate the Fourth Amendment and Sixth Amendment to the Lease. If Landlord does not deliver the Second Expansion Premises to Tenant prior to expiration of such thirty (30) day period, Tenant may terminate the Fourth Amendment and Sixth Amendment to the Lease by providing written notice to Landlord within ten (10) days after the end of the 30-day period. If Tenant elects to terminate the Fourth Amendment and Sixth Amendment to the Lease, such Amendments will be automatically null, void and of no further force or effect. If Landlord so elects, the parties agree to execute an instrument which confirms and effects a release and surrender of all of Tenant’s right, title and interest in and to the Second Expansion Premises pursuant to the terms of the Lease and otherwise, provided that failure of either party of execute such instrument shall not affect such termination. If Tenant fails to provide such termination notice within the time period set forth above, time being of the essence, Tenant will be deemed to have irrevocably waived such termination right.

(b) Provided that Tenant has not exercised its termination right contained in Section 3(a) above, Landlord will proceed diligently and use reasonable efforts to deliver to Tenant possession of the Second Expansion Premises. If Landlord fails to deliver possession of the Second Expansion Premises in the Improvable Condition on or prior to December 31, 2016, Landlord will grant to Tenant a credit (the “Expansion Rent Credit”) equal to $1,074.07 multiplied by the number of days in the period beginning on December 31, 2016, and ending on the day on which Landlord delivers to Tenant possession of the Second Expansion Premises in the Improvable Condition, inclusive. Except for such Expansion Rent Credit, as herein provided, and except for the termination right set forth in Section 3(a) above, there will be no other liability against Landlord for failure to deliver possession of the Second Expansion Premises in the Improvable Condition. Landlord will apply such Expansion Rent Credit (if any) against Base Rent coming due under this Lease in the order in which such Base Rent becomes due.

(c) The “Second Expansion Effective Date” will be the 91^st day following the date that Landlord delivers the Second Expansion Premises to Tenant in the Improvable Condition. The lease term for the Second Expansion Premises shall be co-terminus with the lease term for the balance of the Premises (i.e., the last day of the 84^th full calendar month after the Second Expansion Effective Date). Landlord and Tenant agree, upon demand by the other, to execute and deliver a Commencement Date Agreement in the form of Exhibit B attached to this Sixth Amendment to Lease. If Landlord makes such demand upon Tenant but Tenant fails to respond within fifteen (15) days, then Tenant will irrevocably be deemed to have agreed with Landlord as to the information set forth in the Commencement Date Agreement so delivered by Landlord to Tenant.”

2 – SIXTH AMENDMENT TO LEASE

3. Tenant’s Work. Tenant shall improve the Second Expansion Premises pursuant to the Work Letter attached to this Sixth Amendment to Lease as Exhibit A (the “Work Letter”). Landlord shall, as provided in the Work Letter, provide a tenant improvement allowance in the amount of $794,000.00 (the “Allowance”) and will reimburse at the time of disbursing the Allowance up to $2,977.50 of space planning costs.

4. Deletion of Tenant Obligation to Pay Moving Expenses. Section 7 of the Fourth Amendment is hereby deleted and is of no force or effect.

5. Preparation and Condition of the Premises.

(a) The Work Letter attached to the Fourth Amendment as Exhibit B is hereby deleted.

(b) Section 5 of the Fourth Amendment is hereby restated as follows:

“5. Preparation and Condition of the Premises. As of the date of this Amendment set forth above, Landlord has not received written notice of any defect or need for repair in the Second Expansion Premises which remains uncured. Landlord shall continue to maintain and repair the Second Expansion Premises to the extent Landlord is obligated to do so pursuant to the provisions of the current lease for the Second Expansion Premises until the Second Expansion Premises are delivered to Tenant as provided in this Amendment. Subject to the foregoing, Landlord is leasing the Second Expansion Premises to Tenant “AS IS” and “With All Faults”, without any representations or warranties of any kind (including, without limitation, any express or implied warranties of merchantability, fitness or habitability) except for Landlord’s express obligations under the Lease. Landlord will have no responsibility for the cost of Tenant’s Work except as expressly provided in the Work Letter. Taking possession of the Second Expansion Premises by Tenant will be conclusive evidence as against Tenant that the Second Expansion Premises were in good and satisfactory condition when possession was so taken.

Subject to the initial two (2) sentences in the immediately preceding paragraph, during the Extension Term, Landlord is leasing the Initial Premises to Tenant “AS IS” and “With All Faults”, without any representations or warranties of any kind (including, without limitation, any express or implied warranties of merchantability, fitness or habitability) except for Landlord’s express obligations under the Lease. Tenant acknowledges that it is currently in possession of the Initial Premises and that the Initial Premises are in good and satisfactory condition.”

Each party hereto hereby represents and warrants to the other that in connection with this Amendment, the party so representing and warranting has not dealt with any real estate broker, agent or finder, except for Cresa and Jones Lang LaSalle Americas, Inc. (each, a “Broker”), and, to its knowledge no other broker initiated or participated in the negotiation of this Amendment, submitted or showed the applicable premises to Tenant or is entitled to any commission in connection with this Amendment. Each party hereto will indemnify, defend and hold harmless the other against any and all claims, costs, liabilities and expenses (including, without limitation, reasonable attorneys’ fees) in connection with any inaccuracy in such party’s representation.

9. Stipulation. The Premises are stipulated for all purposes to contain the number of rentable square feet as set forth in this Amendment.

This Amendment may be executed in any number of counterparts and by each of the undersigned on separate counterparts and may be delivered by facsimile or other electronic delivery (such as, without limitation, scanned signatures in .pdf format), and each such counterpart will be deemed to be an original, but all such counterparts will together constitute but one and the same Amendment.

11. Time of Essence. Time is of the essence of this Amendment.

12. No Offer. Submission of this instrument for examination or negotiation will not bind Landlord, and no obligation on the part of Landlord will arise until this Amendment is executed and delivered by both Landlord and Tenant. However, the execution of this Amendment by Tenant and delivery thereof to Landlord or Landlord’s agent will constitute an irrevocable offer by Tenant on the terms and conditions herein contained, which offer may not be revoked for thirty (30) days after such delivery.

13. Entire Agreement. This Amendment and the Lease contain all the terms, covenants, conditions and agreements between Landlord and Tenant relating to the matters provided for in this instrument. No prior or other agreement or understanding pertaining to such matters other than the Lease will be valid or of any force or effect. This Amendment may only be modified by an agreement in writing signed by Landlord and Tenant.

14. Joint and Several Liability. If this Amendment is signed, or if the obligations of Tenant are otherwise guaranteed, by more than one party, their obligations shall be joint and several, and the release or limitation of liability of any one or more of the parties shall not release or limit the liability of any other party.

5 – SIXTH AMENDMENT TO LEASE

As an essential inducement to Landlord to execute this Amendment, Tenant hereby certifies and warrants to and agrees with Landlord that (a) no event of default by Landlord under the Lease exists as of the date hereof, nor has any event occurred which, with the passage of time or the giving of notice, or both, would constitute an event of default, (b) Landlord is not in any manner in default in the performance or observance of any obligation or duty owed to Tenant, under the Lease or otherwise, and (c) Tenant has no defenses, offsets, claims or counterclaims to the observance and performance by Tenant of any provision of the Lease or this Amendment, or, if any such defenses, offsets, claims or counterclaims exist, they are hereby forever waived, released and settled in consideration of this Amendment.

The installation of such Tenant Improvements is herein referred to as “Tenant’s Work.” The installation of such Tenant Improvements shall be accomplished in accordance with this Work Letter and also all other applicable provisions of the Lease; without limiting the foregoing, the parties agree that the Tenant’s Work is “Work” as defined by Article 9 of the Original Lease, and that all provisions of the Lease applicable to “Work” apply to the Tenant’s Work. In the event of a conflict, the provisions of this Exhibit shall control over the provisions of the Lease.

3. Plans.

The final plans and specifications as approved by Landlord are herein referred to as the “Final Plans.” Landlord shall, as part of Landlord’s prior written approval, confirm in writing any portion of Tenant’s Work required to be removed from the Premises by Tenant upon the expiration or earlier termination of the Lease.

4. Permits and Approvals.

1 – EXHIBIT A

c. Subcontractors. Tenant and its general contractor shall employ only subcontractors approved by Landlord as provided in Article 9 of the Original Lease to perform mechanical, HVAC, electrical and plumbing work. Approval of any such subcontractor by Landlord does not impose any obligation or liability upon Landlord.

6. Construction. Tenant shall comply with the following provisions.

a. Course of work. Tenant’s Work shall be conducted as set forth in Article 9 of the Original Lease.

b. Deliveries. Upon final completion, Tenant shall deliver to Landlord the following:

7. Payment Contribution.

Tenant shall submit evidence of compliance with the foregoing requirements to Landlord following final completion and shall make the deliveries listed in Section 6b. Within thirty (30) days following the later of Tenant opening for business at the Second Expansion Premises and Tenant making such submission and deliveries, Landlord shall pay to Tenant the Costs of Tenant’s Work up to the amount of the Allowance (as those terms are defined herein), as follows.

2 – EXHIBIT A

a. Allowance. The Costs of Tenant’s Work shall be reimbursed by Landlord up to the amount of the Allowance; the Allowance shall not be used for trade fixtures, equipment or personal property. If the Costs are less than the Allowance, then the amount of the Allowance will be automatically reduced to equal the Costs. If any part of the Allowance is not used to pay Costs by the second anniversary of delivery of the Second Expansion Premises, the unused part of the Allowance is forfeited and will not be available for any purpose, it being the responsibility of Tenant to plan the remodeling process to allow Tenant’s Work to be completed and Tenant’s right to reimbursement to be perfected by such date.

b. Costs. The “Costs” of Tenant’s Work are all hard and soft costs related to Tenant’s Work including but not limited to architectural plans, permits, and construction costs. Costs shall include a construction oversight fee of 3% of the Allowance, to be deducted from the Allowance and paid to Landlord’s agent; Tenant shall not be required to pay Landlord any other sums in connection with Tenant’s Work, including without limitation, as set forth in Article 9(F) of the Lease. Tenant shall pay all Costs as and when due.

c. Default. No disbursement of the Allowance shall be due or paid at any time that a Default exists under the Lease.

8. Construction Oversight. Tenant shall provide all project management and oversight of Tenant’s Work necessary for Tenant to perform its obligations hereunder. Landlord and/or its property manager (or designee) shall be given the schedule for all project meetings and shall have the right to attend all such meetings. Landlord and Landlord’s agents shall have the right, but not the obligation, to inspect the construction of Tenant’s Work as provided in Article 9(B) of the Lease. However, neither the right herein granted to Landlord to make such inspections, nor the making of such inspections by Landlord, shall operate as a waiver of any rights of Landlord to require good and workmanlike performance of all Tenant’s Work in accordance with the requirements of this Work Letter. Notwithstanding any inspection or acceptance by Landlord of Tenant’s Work, or any portion thereof, Tenant acknowledges that Landlord’s sole interest in doing so is to protect the Building and Landlord’s interests. Accordingly, Tenant shall not rely upon Landlord’s inspections or approvals, and agrees that Landlord shall not be the guarantor of, nor responsible for, any of Tenant’s Work. Tenant shall be solely responsible for, and shall remedy, at Tenant’s sole expense, any and all defects in Tenant’s Work that may appear during or after the completion thereof, whether the same shall affect the Second Expansion Premises in particular or any part of the Building in general.
