11. Tenant Improvements. Tenant accepts the Sixth Expansion Premises in their current as-is condition and repair. The foregoing notwithstanding, Landlord agrees to provide Tenant with an allowance for construction by
Tenant of certain tenant improvements to be incorporated into the Premises, in the amount of Two Hundred Ninety-Six Thousand Eight Hundred Eighty-Seven and 70/100 US Dollars ($296,887.70) (the Construction Credit), which Construction
Credit may be used by Tenant in the manner set forth in Exhibit B-4, attached to this Modification and incorporated by reference. Landlord shall be paid a construction management supervisory fee out of the Construction Credit equal to one
percent (1%) of the hard construction costs of the tenant improvements to be constructed by Tenant, specifically excluding architectural fees, project management fees, permitting, cabling, furniture, fixtures and equipment. Landlords
construction management fee shall be invoiced by and paid to Landlord based upon the invoices submitted by Tenant for reimbursement from Landlord and shall be paid out of the Construction Credit. The Construction Credit shall be paid by Landlord to
Tenant within thirty (30) days of mutual execution of this Modification. Landlord, at its option (which option must be exercised, if at all, at the time that Landlord grants its written approval to Tenants proposed final construction Plans in
the manner described in Exhibit B-5) may require Tenant to remove any physical additions and/or repair any alterations made pursuant to this paragraph or Exhibit B-4, including but not limited to low voltage communications and data
cabling, in order to restore the subject portion of the Premises to the condition existing at the time prior to the commencement of such work, all costs of removal and/or alterations to be borne by Tenant.

In addition to the foregoing, and provided that Tenant is not then in default of the Lease beyond any applicable period of notice and cure, on January 1,
2012, and following written request therefor from Tenant to Landlord, Landlord agrees to provide Tenant with a refurbishment allowance for construction by Tenant of certain tenant improvements to be incorporated into the Premises, in the amount of
Two Hundred Fifty Thousand and No/100 US Dollars ($250,000.00) (the Refurbishment Allowance), which Refurbishment Allowance shall be used by Tenant subject to the provisions of Article 6.00 of the Lease. Any portion of the Refurbishment
Allowance not used by Tenant for improvements to the Premises by December 31, 2012 shall revert back to, and shall be paid by Tenant to Landlord.

12. Right Of Offer To Lease  First Floor. Tenants Right of Offer contained in Paragraph 12 of the Seventh Modification and Ratification of Lease shall be deleted in its entirety.

13. Extension Option. Provided no event of default (or no event which, with the passage of time or
the giving of notice or both, would constitute an event of default under the Lease) has occurred and is continuing beyond any applicable period of notice and cure, and provided Tenant has not assigned the Lease or shall then have currently sublet
all or any portion of the Premises, Tenant shall have one option to extend the term of this Lease for all of the Original Premises, Expansion Premises, Second Expansion Premises, Third Expansion Premises, Fourth Expansion Premises, Fifth Expansion
Premises and Sixth Expansion Premises (but not for any separate part thereof) for an additional five (5) year term by giving the Landlord written notice at least twelve (12) months, but no more than eighteen (18) months, prior to the expiration of
the then current term of this Lease. Upon the giving of such notice, this Lease shall be considered as extended for such option term upon the same terms, conditions and covenants as are contained in this Lease except that there shall be no
additional extension options, Landlord shall not be obligated to provide Tenant with any tenant improvement allowance (except as otherwise specifically negotiated between Landlord and Tenant) and except that charges for parking and for after hours
HVAC shall be calculated at the rates then being charged by Landlord to other tenants in the Building for such services and except that the base rent shall be calculated by multiplying the number of rentable square feet of the Premises by the
then-fair-market-base-rental-value, which then-fair-market-base-rental-value shall be determined in the manner set forth below.



| | (a) | Landlord and Tenant will have thirty (30) days after Landlord receives the Tenants notice of its intent to exercise any extension within which to agree on the
then-fair-market-base-rental-value of the Premises. If they agree on the fair market base rent for the subject option period within thirty (30) days, they will amend this Lease by stating the new base rent for the option period.
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (b) | If Landlord and Tenant are unable to agree on the then-fair-market-base-rental-value of the Premises for the option period within thirty (30) days, then the base rent for the option
period will be the then-fair-market-base-rental-value of the Premises as determined in accordance with subparagraph d below.
| | --- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (c) | The then-fair-market-rental-value of the Premises means what a landlord under no compulsion to Lease the Premises and a tenant under no compulsion to lease the Premises
would determine as rents (including initial monthly rent and rental increases) for the option period, as of the commencement of the option period and determined according to recent market lease transactions in comparable buildings located in the
market area of the Premises, taking into consideration the uses permitted under this Lease, the quality, size, design and location of the Premises, the credit-worthiness of the Tenant, allowances for rental abatement, moving and tenant finish, if
any, and any other factor reasonably related to the determination of rental values.
| | --- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (d) | If Landlord and Tenant are unable to agree upon the then fair market base rental value of the Premises, within fifteen (15) days after the expiration of
| | --- | --------------------------------------------------------------------------------------------------------------------------------------------------------



6



---

| | the thirty (30) day period set forth in subparagraph a. above, Landlord and Tenant will each appoint a commercial real estate broker with at lease ten (10)
years full-time commercial experience in the area in which the Premises are located to determine the then-fair market rental value of the Premises. If either Landlord or Tenant does not appoint a commercial real estate broker within ten (10)
days after the other has given notice of the name of its broker, the single broker appointed will be the sole appraiser and will set the then-fair market rental value of the Premises. If two commercial real estate brokers are appointed pursuant to
this paragraph, they will meet promptly and attempt to set the then-fair market rental value of the Premises. If they are unable to agree within thirty (30) days after the second commercial real estate broker has been appointed, they will attempt to
elect a third commercial real estate broker meeting the qualifications stated in this paragraph within ten (10) days after the last day the two commercial real estate brokers are given to set the then fair market rental value of the Premises. If
they are unable to agree on a third commercial real estate broker, either Landlord or Tenant, by giving ten (10) days prior notice to the other, can apply to the then presiding judge of the District Court in and for the City and County of
Denver for the selection of a third commercial real estate broker who meets the qualifications stated in this paragraph. Landlord and Tenant will bear one-half (1/2) of the cost of appointing the third commercial real estate broker and of paying the
third commercial real estate brokers fee. The third commercial real estate broker, however selected, must be a person who has not previously acted in any capacity for either Landlord or Tenant.
| | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (e) | Within thirty (30) days after the selection of the third commercial real estate broker, a majority of the brokers will set the then-fair market rental value of the Premises. If a
majority of the brokers are unable to set the then-fair market rental value of the Premises within thirty (30) days after selection of the third commercial real estate broker, the third appraiser shall select either the then-fair market rental value
for the Premises established by Landlords appointed commercial real estate broker, or the Tenants appointed commercial real estate broker.
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

14. Real Estate Brokers. Each of the parties hereto hereby warrants and represents to the other party that it has not dealt with or been represented by any broker in connection with its execution of this
Modification other than Landlords listing agent, Cushman & Wakefield of Colorado, Inc., acting as the limited agent of Landlord, and The Staubach Company, acting as the limited agent of Tenant. Tenant agrees to indemnify and hold Landlord
harmless from and against any other claims for commissions or similar compensation from any other person claiming an entitlement to any such payment as a result of its representation of Tenant. In addition, Landlord agrees to indemnify and hold
Tenant harmless from and against any claims for commissions or similar compensation from any other broker or person claiming an entitlement to any such payment as a result of its representation of Landlord.
