thereof. All references to square footage of the Leased Premises contained in the Lease shall be revised accordingly.

(60) months following the Amendment Commencement Date (the “Amended Primary Lease Term”). Following the Amendment Commencement Date, all references in the Lease to the “Primary Lease Term” shall thereafter refer to
the Amended Primary Lease Term. 
 3. Completion of the Premises. Section 3 of the Lease is hereby deleted in its

Commencement Date and, thereafter, on the first day of each calendar month; provided, however, the first 1/2 month of Base
Rent for the Expansion Premises shall be abated. Monthly installments of Base Rent for any partial calendar month shall be prorated based upon the number of days in such calendar month. On each anniversary of the Lease, annual Base Rent will be
increased by an amount equal to 3.25% of the annual Base Rent for the previous Lease Year without any further notice to Tenant. 

5. Tenant’s Proportional Share. Tenant’s Proportional Share shall be approximately 34.4%, subject to adjustment based
upon verification of the square footage of the Expansion Premises. All references in the Lease to Tenant’s Proportional Share shall be revised accordingly.

attributable to the portion of the Leased Premises excluding the Expansion Premises for the Amended Primary Lease Term, less (ii) Base Rent for the Primary Term under the Lease prior to this First Amendment (the “Commission”).
One-half of the Commission shall be due and payable by Landlord to Equis Corporation upon execution of this First Amendment, with the balance due and payable on the Amendment Commencement Date.

 9. Access to Premises. Section 33 of the Lease is hereby amended by the addition
of the following Section 33.01 (j): 
 (j) Tenant shall be permitted to access the Premises at any time;
provided, however, Tenant shall be solely responsible for payment of any costs and expenses associated with access outside normal Building hours, including, without limitation, costs of HVAC services described in Section 7.00. 

10. Right of First Offer. During the Amended Primary Lease Term and any renewal term, Tenant shall have a right of first offer to
lease any available space located on the first floor of the Building in accordance with the terms and conditions of Section 37 of the Lease. 
 11. Option to Extend. Section 38 of the Lease is hereby deleted in its entirety and replaced with the following: 

38.01 Option to Extend Amended Primary Lease Term. Upon the full and complete performance of all terms, covenants
and conditions contained in the Lease by Tenant and the payment of all Rent and other sums due under the terms of the Lease, Tenant shall have the option to renew the Lease for one (1) additional term of three (3) years (the
“Renewal Term”). If Tenant desires to exercise this option, Tenant must deliver written notice of its election to Landlord not less than nine (9) months prior to the expiration of the Amended Primary Lease Term. If Tenant
exercises this option, the Lease, and all terms and provisions thereof, shall be deemed to be extended for the Renewal Term, subject to the right of Landlord to make any adjustments and to assess any charges against Tenant which are provided in the
Lease. Base Rent for the Renewal Term shall be at the then-current market rate with reasonable annual increases, all as determined by an appraiser engaged by the parties with expertise in office lease rates in the Boulder County area. If the parties
cannot agree on an appraiser to make such determination, each party may hire an appraiser and the Base Rent and increases thereof for the Renewal Term shall be the average of the recommendations of the appraisers.

approximately 56 parking spaces, subject to adjustment based upon verification of the square footage of the Expansion Premises.
