 Exhibit 10.12 
 FIRST AMENDMENT TO LEASE 
 THIS FIRST AMENDMENT
TO LEASE (this “Amendment”) is entered into as of this 21st day of May, 2009, by and between BMR-530 FAIRVIEW AVENUE LLC, a Delaware limited liability company (“Landlord”), and NANOSTRING TECHNOLOGIES, INC. (“Tenant”).

 RECITALS 
 A. WHEREAS, Landlord and Tenant entered into that certain Lease dated as of October 19, 2007 (as the same may have been amended, supplemented or otherwise modified from time to time, the
“Lease”), whereby Tenant leases certain premises (the “Premises”) from Landlord at 530 Fairview Avenue in Seattle, Washington (the “Building”); and 

B. WHEREAS, Landlord and Tenant desire to modify and amend the Lease only in the respects and on the conditions hereinafter stated.

 AGREEMENT 
 NOW, THEREFORE, Landlord and Tenant, in consideration of the mutual promises contained herein and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged,
and intending to be legally bound, agree as follows: 
 1. Definitions. For purposes of this Amendment, capitalized terms
shall have the meanings ascribed to them in the Lease unless otherwise defined herein. The Lease, as amended by this Amendment, shall be referred to herein as the “Amended Lease.” 

2. Sales Tax. 
 a. Retail sales tax otherwise applicable to portions of construction of the Building and Tenant Improvements and other improvements made or requested by Tenant may be eligible for deferral pursuant to RCW
82.63 (the “Sales Tax Deferral”) as a result of the uses of the Premises intended by Tenant. Landlord shall make application with the Washington State Department of Revenue (the “State”) for the Sales Tax Deferral
with respect to work to be performed and paid for by Landlord pursuant to the Amended Lease. When the State has determined the final amount of the sales tax which Landlord may defer pursuant to the Sales Tax Deferral Program, Landlord will provide
Tenant with written notice of such amount. 
 b. Tenant agrees if a subsequent audit by the State determines that
(a) because Tenant’s use of the Premises has changed or (b) for any other reason, any of the sales tax previously deferred pursuant to the Sales Tax Deferral is now due and owing to the State, then Tenant shall pay to Landlord, within
ten (10) days following the date Landlord notifies Tenant of any such determination by the State, an amount equal to the amount required to be paid to the State, including any penalties and interest due to the State; provided that Tenant
may conduct a good faith contest of any such determination by the State in accordance with appropriate administrative procedures so long as payment of the amount claimed by the State is stayed during the conduct of the contest. If Tenant desires to
dispute the amount claimed by the 







 
State to be due but payment of such amount is not stayed during the conduct of the proceedings, Tenant shall pay the amount due but at Tenant’s request, Landlord shall pay the amount claimed
by the State under protest. 
 c. Landlord shall reasonably cooperate with and assist Tenant in any challenges or audits to the
Sales Tax Deferral benefit. Landlord shall promptly notify Tenant of any such action of which Landlord becomes aware, and shall promptly forward any correspondence regarding any such challenge or audit. Tenant shall have the right to contest or
review on its own behalf (but not on Landlord’s behalf) any proceedings regarding the Sales Tax Deferral benefit that may be instituted, either before, during or after the Term of the Amended Lease. Landlord shall, on a timely basis, execute
all necessary instruments in connection with any such protest, appeal or other proceedings, at no cost to Landlord. If any proceeding may only be instituted and maintained by Landlord, then Landlord shall do so at Tenant’s cost upon the request
of Tenant, unless Landlord reasonably objects. 
 3. Back-Up Generator. Landlord will install a back-up generator in the
basement of the Building and connect the Generator to the Premises’ existing emergency electrical panel (the “Generator”). Tenant shall be entitled to use up to twenty kilowatts of power from the Generator on a non-exclusive
basis with other Tenants in the Building. The cost of maintaining, repairing and replacing the Generator shall constitute Operating Expenses. Landlord shall remove the generator installed by Tenant on the roof of the Building within thirty
(30) days after the Generator becomes operational and deliver the same to the Building loading dock. Tenant shall promptly remove the Generator from the loading dock and the Project. Tenant shall have no right to place additional generators at
the Project, unless agreed to in advance in writing by Landlord. Landlord expressly disclaims any warranties with regard to the Generator or the installation thereof, including, without limitation, any warranty of merchantability or fitness for a
particular purpose. Landlord shall maintain the Generator in good working condition, but shall not shall not be liable for any failure to make any repairs or to perform any maintenance that is an obligation of Landlord unless such failure shall
persist for an unreasonable time after Tenant provides Landlord with written notice of the need of such repairs or maintenance. The provisions of Section 17.2 of the Lease shall apply to the Generator. 

4. Broker. Tenant represents and warrants that it has not dealt with any broker or agent in the negotiation for or the obtaining
of this Amendment other than Landlord’s Broker and Tenant’s Broker, and agrees to indemnify, defend and hold Landlord harmless from any and all cost or liability for compensation claimed by any other broker or agent employed or engaged by
it or claiming to have been employed or engaged by it. 
 5. Effect of Amendment. Except as modified by this Amendment,
the Lease and all the covenants, agreements, terms, provisions and conditions thereof shall remain in full force and effect and are hereby ratified and affirmed. The covenants, agreements, terms, provisions and conditions contained in this Amendment
shall bind and inure to the benefit of the parties hereto and their respective successors and, except as otherwise provided in the Lease, their respective assigns. In the event of any conflict between the terms contained in this Amendment and the
