(the “Lease”) for the lease of certain premises (the “Premises”) known as Suite 260 and located in a portion of the building (the “Building”) located at 1601 Dry Creek Drive, Longmont, Colorado, as

and 11,263 square feet of storage space, substantially as shown cross-batched or outlined on Exhibit A-1 attached hereto, provided that the Rentable Area of Office Space and the Rentable Area of Storage Space shall be subject to adjustment as set

 5. With respect to the portion of the Lease Term commencing on the Conversion Date, Tenant’s
Proportionate Share of Operating Costs for Office Space, as set forth in Section 4(a) of the Lease, shall be 31,802%. 
 6.
The “Conversion Date” shall be the earlier of (i) March 1, 2012 or (ii) the date on which Tenant’s Conversion Work, as defined below, is substantially complete, as defined below. 

7. Tenant shall be responsible for making any alterations or improvements necessary to cause the Conversion Space to be usable as general
office space, subject to Landlord’s 







 
approval as hereinafter provided, at Tenant’s sole cost and expense except that Landlord shall provide Tenant with the Conversion Allowance as a contribution towards the costs of
Tenant’s Conversion Work, as hereinafter defined. Promptly after the date of this Amendment, Tenant shall cause its architect (who shall be licensed in the State of Colorado) to prepare schematic diagrams and a set of drawings (such schematic
diagrams and drawings being hereinafter referred to as “Tenant’s Conversion Plans”) to be used by Tenant for the design and permitting of Tenant’s Conversion Work, which Tenant’s Conversion Plans shall show the
alterations and improvements that Tenant intends to make to the Conversion Space, and Tenant shall deliver Tenant’s Conversion Plans to Landlord no later than two (2) weeks prior to the date on which Tenant intends to commence
Tenant’s Conversion Work. Landlord shall respond to Tenant’s Conversion Plans (either by approval, request for additional information, request for revision or communication of a reason for failure to approve) within five (5) business
days (meaning all calendar days except Saturdays and Sundays and holidays observed by banks in the State of Colorado) after the date of Landlord’s receipt of Tenant’s Conversion Plans (or any resubmission), plus such additional period of
time as may be necessary for review of Tenant’s Conversion Plans by a third-party architect, engineer or other consultant if Landlord determines that any aspect of Tenant’s Conversion Plans requires such third-party review. Unless Landlord
shall have unconditionally approved all of Tenant’s Conversion Plans, Tenant shall deliver to Landlord such additional information, documentation and/or revisions to Tenant’s Conversion Plans as are necessary to obtain Landlord’s
approval of Tenant’s Conversion Plans and this process shall continue until Tenant’s Conversion Plans are approved by Landlord. 
 After approval of Tenant’s Conversion Plans by Landlord and receipt of all applicable permits from the local governing authority, copies of which shall be delivered to Landlord prior to the
commencement of Tenant’s Conversion Work, Tenant shall cause its contractor(s) and subcontractor(s) to perform the work specified therein (“Tenant’s Conversion Work”) in accordance with Tenant’s Conversion Plans,
diligently and continuously until Tenant’s Conversion Work is substantially complete. Tenant’s Conversion Work shall be performed in compliance with the provisions and requirements of Exhibit B to the Lease and all other applicable
provisions of the Lease; in a good and workmanlike manner; by contractors and subcontractors approved by Landlord; in compliance with all applicable laws, codes, regulations, permits and approvals; at such times and in such manner so as not to
disturb other tenants of the Building or Building operations; and in accordance with any reasonable directions that may be given, from time to time, by Landlord’s agent. Tenant’s contractors and subcontractors shall carry the insurance
required by Section (c) of Exhibit B of the Lease and shall, prior to commencing any work, submit certificates of insurance to Landlord’s agent evidencing that all such required insurance is in effect. 

Tenant’s Conversion Work shall be deemed to be substantially complete on the first day as of which Tenant’s Conversion Work has
been completed except for items of work (and, if applicable, adjustment of equipment and fixtures) which can be completed after occupancy has been taken without causing undue interference with Tenant’s use of the Conversion Space as office
space (i.e. so-called “punch list” items) and any new or amended certificate of occupancy, letter of completion or similar documentation from the City of Longmont necessary as a result of such Tenant Conversion Work has been issued.

 Provided the Lease is in full force and effect and Tenant is not in default hereunder, then Landlord will provide Tenant with
the Conversion Allowance in an amount not to exceed $12.73 







 
per square foot of Conversion Space, which shall be used and disbursed in accordance with the provisions and procedures set forth in Exhibit B to the Lease relating to the Office Space, except
that prior to the release of the remainder of the Conversion Allowance Tenant shall deliver to Landlord, in addition to the items required by Section (a)(ii) of Exhibit B of the Lease, a record set of plans incorporating and documenting each change
that is a variance from the approved Tenant’s Conversion Plans, which record set shall be provided to Landlord in hard copy and Auto CADD format. 
 Both Landlord and Tenant shall appoint one individual as its “Construction Representative” who is authorized to act on its behalf in connection with any matters arising pursuant to this
Section 7. The Construction Representative may be changed from time to time by notice hereunder from the then current Construction Representative to the other party’s Construction Representative or by notice from Landlord or Tenant
pursuant to Section 19(c) of the Lease. The initial Construction Representatives shall be Sandy Grasso (Landlord) and Robin Kirchenbauer (Tenant). Notwithstanding Section 19(c) of the Lease, any notices or other communication under this
Section 7 may be made by letter or other writing sent by U.S. mail, facsimile or email, provided the communication is made by one party’s Construction Representative to the other party’s Construction Representative. 

8. The parties acknowledge that the square footage of the Conversion Space, as set forth in this Amendment, is an estimate only, and that
upon delivery of the record set of plans to Landlord, as required by Section 7 above, the parties shall execute a confirmatory document or amendment to the Lease setting forth the actual square footage of the Conversion Space and the necessary
adjustments to the Rentable Area of Office Space, Rentable Area of Storage Space, Base Annual Rent for Office Space, Base Annual Rent for Storage Space and Tenant’s Proportionate Share of Operating Costs for Office Space to reflect such actual
square footage. 
 9. The parties acknowledge the existence of asbestos in the floor adhesive in the Conversion Space which was
not previously required to be abated by Landlord. In connection with the performance of Tenant’s Conversion Work, Tenant, using industry accepted standards, shall remove such asbestos from the Conversion Space (the “Remediation
Work”). The Remediation Work shall be performed in compliance with all Hazardous Materials Laws and the Remediation Plan, as defined below. Following such necessary actions, Tenant shall provide written evidence of such actions to Landlord.

 Tenant shall obtain a bid for the performance of the Remediation Work and shall submit same to Landlord for Landlord’s
review and approval, which shall include approval of the proposed contactor, remediation plan and price (collectively, the “Remediation Plan”). Upon Landlord’s approval of the Remediation Plan, Tenant shall cause the
Remediation Work to be performed to completion in accordance with the approved Remediation Plan. Upon completion of the Remediation Work and submission to Landlord of (i) an itemized statement of the costs of the Remediation Work,
(ii) complete copies of paid bills for the Remediation Work, (iii) full and final lien waivers from all contractors, subcontractors and suppliers in connection with the Remediation Work, as applicable, and (iv) evidence that any
required governmental inspections and approvals have been successfully completed, Landlord shall reimburse Tenant for the cost of the performance of the Remediation Work in an amount not to exceed the amount set forth in the approved Remediation
Plan.
