FAIRVIEW AVENUE LLC, a Delaware limited liability company (“Landlord”), and
NANOSTRING TECHNOLOGIES, INC., a Delaware corporation (“Tenant”).
RECITALS
A.WHEREAS, Landlord and Tenant are parties to that certain Lease dated as of
December 22, 2014 (as the same may have been amended, supplemented or modified
from time to time, the “Existing Lease”), whereby Tenant leases certain premises
(the “Original Premises”) from Landlord at 500 Fairview Avenue North, Seattle,
Washington (the “Building”);

B.WHEREAS, Landlord desires to lease additional premises to Tenant; and

C.WHEREAS, Landlord and Tenant desire to modify and amend the Existing 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 Existing Lease unless otherwise defined herein.
The Existing Lease, as amended by this Amendment, is referred to collectively
herein as the “Lease.” From and after the date hereof, the term “Lease,” as used
in the Existing Lease, shall mean the Existing Lease, as amended by this
Amendment.

2.Seventh Floor Premises. Effective as of January 1, 2017 (the “7th Floor Term
Commencement Date”), Landlord hereby leases to Tenant and Tenant hereby leases
from Landlord approximately nineteen thousand one (19,001) square feet of
Rentable Area located on the seventh floor of the Building (as shown on Exhibit
A attached hereto, the “7th Floor Premises”), including any exclusive shafts,
cable runs, mechanical spaces and rooftop areas. From and after the 7th Floor
Term Commencement Date, the term “Premises” as used in the Existing Lease shall
mean the Original Premises plus the 7th Floor Premises.

3.Permitted Use. Notwithstanding Section 2.7 of the Existing Lease, Tenant shall
be permitted to use the 7th Floor Premises for office and laboratory use and
light manufacturing in compliance with all Applicable Laws and for no other use
(the “7th Floor Permitted Use”).

4.Term. The term with respect to the 7th Floor Premises (the “7th Floor Premises
Term”) shall commence on the 7th Floor Term Commencement Date and shall expire
on the Term Expiration Date, subject to extension or earlier termination of the
Lease as provided therein.

5.Base Rent. In addition to the Base Rent for the Original Premises and the
Storage Space, commencing on the 7th Floor Term Commencement Date, Tenant shall
pay to Landlord the sums set forth below as Base Rent for the 7th Floor
Premises, subject to adjustment under the Lease. In accordance with Article 8 of
the Existing Lease, the Base Rent for the 7th Floor Premises shall be subject to
an annual upward adjustment of three percent (3%) of the then-current Base Rent.
The first such adjustment shall become effective commencing on the first (1st)
anniversary of the 7th Floor Term Commencement Date, and subsequent adjustments
shall become effective on every successive annual anniversary during the 7th
Floor Premises Term. Notwithstanding anything to the contrary herein, Base Rent
for the 7th Floor Premises shall be abated during the first four (4) months of
the 7th Floor Premises Term (the “7th Floor Base Rent Abatement Period”). For

become part of the Security Deposit. The 7th Floor Security Deposit may be in
the form of cash, a letter of credit that satisfies the requirements for L/C
Security or any other security instrument approved by Landlord in its sole
discretion.

8.7th Floor TI Allowance; Construction of 7th Floor Tenant Improvements.

(a)    7th Floor TI Allowance. Following the Amendment Execution Date, Landlord
shall make available to Tenant a tenant improvement allowance (the “7th Floor TI
Allowance”) in the amount of Two Million Four Hundred Seventy Two Thousand Nine
Hundred Eighty and 15/100 Dollars ($2,472,980.15) (based upon One Hundred Thirty
and 15/100 Dollars ($130.15) per square foot of Rentable Area of the 7th Floor
Premises) in order to fund tenant improvements (the “7th Floor Tenant
Improvements”) to the 7th Floor Premises consistent with the 7th Floor Permitted
Use. Tenant shall cause the 7th Floor Tenant Improvements to be constructed in
the 7th Floor Premises pursuant to the work letter attached hereto as Exhibit B
(the “7th Floor Work Letter”) at a cost to Landlord not to exceed the 7th Floor
TI Allowance (as the same may be adjusted pursuant to the 7th Floor TI Allowance
Reallocation Right [defined below]), subject to Landlord’s obligations under
Section 2.3(a) of the 7th Floor Work Letter regarding costs incurred with
respect to any Change (as defined in the 7th Floor Work Letter) requested by
Landlord. The 7th Floor TI Allowance may be applied to the costs of (m)
construction, (n) project review by Landlord (which fee, as set forth in Section
17.10 of the Existing Lease, shall equal two percent (2%) of the cost of the 7th
Floor Tenant Improvements, including the 7th Floor TI Allowance, but shall not
exceed Forty Thousand and No/100 Dollars ($40,000.00)), (o) commissioning of
mechanical, electrical and plumbing systems by a licensed, qualified
commissioning agent hired by Tenant, and review of such party’s commissioning
report by a licensed, qualified commissioning agent hired by Landlord, (p) space
planning, architect, engineering and other related services performed by third
parties unaffiliated with Tenant, (q) building permits and other taxes, fees,
charges and levies by Governmental Authorities for permits or for inspections of
the 7th Floor Tenant Improvements, and (r) costs and expenses for labor,
material, equipment and fixtures, provided that no more than five percent (5%)
of the 7th Floor TI Allowance may be applied towards the cost of the purchase
and installation of cabling and telecom improvements within the 7th Floor
Premises. In no event shall the 7th Floor TI Allowance be used for (v) the cost
of work that is not authorized by the Approved Plans (as defined in the 7th
Floor Work Letter) or otherwise approved in writing by Landlord (which approval
shall not be unreasonably withheld, conditioned or delayed), (w) payments to
Tenant or any affiliates of Tenant, (x) except as otherwise provided in this
Section, the purchase of any furniture, personal property or other non-building
system equipment, (y) costs resulting from any default by Tenant of its
obligations under the Lease or (z) costs that are recoverable by Tenant from a
third party (e.g., insurers, warrantors, or tortfeasors). Notwithstanding
anything to the contrary in this Amendment, Landlord shall not charge Tenant any
plan or construction review, oversight, supervision, management or other similar
fee in relation to the 7th Floor Tenant Improvements other than the amount set
forth in clause (n) above. In addition to the 7th Floor TI Allowance, Landlord
shall contribute up to Two Thousand Eight Hundred Fifty and 15/100 Dollars
($2,850.15) (based upon 15/100 Dollars ($0.15) per square foot of Rentable Area
of the 7th Floor Premises) to pay the cost of developing a test fit plan for the
7th Floor Premises (the “7th Floor Test Fit Allowance”), which shall be
disbursed by Landlord directly to Tenant’s architect in accordance with the 7th
Floor Work Letter.
(b)    7th Floor TI Deadline. Tenant shall have until the date that is one (1)
year after the 7th Floor Term Commencement Date (the “7th Floor TI Deadline”),
to expend the unused portion of the 7th Floor TI Allowance and the 7th Floor
Test Fit Allowance, after which date Landlord’s obligation to fund such costs
shall expire.
(c)    Application of Tenant Allowances. If the cost of the 7th Floor Tenant
Improvements to be performed by Tenant exceeds the amount of the 7th Floor TI
Allowance, then Tenant shall have the right (the “7th Floor TI Allowance
Reallocation Right”) to reallocate all or a portion of any unused TI Allowance
for the Original Premises (the “Original Premises TI Allowance”) under the Lease
(any such reallocated amount, the “7th Floor Reallocated TI Allowance Amount”)
to pay such excess cost of constructing the 7th Floor Tenant Improvements
(subject to the limitations set forth in the Lease), on the terms and conditions
set forth in the 7th Floor TI Allowance Reallocation Agreement attached as
Exhibit C hereto (the “7th Floor TI Allowance Reallocation Agreement”). In no
event shall any unused 7th Floor TI Allowance or 7th Floor Test Fit Allowance
entitle Tenant to a credit against Rent payable under the Lease. Upon Tenant’s
exercise of the 7th Floor TI Allowance Reallocation Right, the Original Premises
TI Allowance shall be permanently reduced by the 7th Floor Reallocated TI
Allowance Amount, and Landlord shall have no further obligation to fund the 7th
Floor Reallocated TI Allowance Amount for the Tenant Improvements for the
Original Premises.
(d)    Excess Costs. Tenant shall be solely responsible for any costs related to
the 7th Floor Tenant Improvements in excess of the 7th Floor TI Allowance (as
the same may be adjusted pursuant to the 7th Floor TI Allowance Reallocation
Right and subject to Landlord’s obligations under Section 2.3(a) of the 7th
Floor Work Letter regarding costs incurred with respect to any Change (as
defined in the 7th Floor Work Letter) requested by Landlord) (the “7th Floor
Excess Costs”). If the amount of the Approved Budget (as defined in the 7th
Floor Work Letter) is greater than the 7th Floor TI Allowance (as the same may
be adjusted pursuant to the 7th Floor TI Allowance Reallocation Right), but less
than or equal to one hundred ten percent (110%) of the 7th Floor TI Allowance
(as the same may be adjusted pursuant to the 7th Floor TI Allowance Reallocation
Right), then Landlord shall first pay the entire 7th Floor TI Allowance, and
after the 7th Floor TI Allowance (as the same may be adjusted pursuant to the
7th Floor TI Allowance Reallocation Right) has been expended, Tenant shall pay
the 7th Floor Excess Costs. If the amount of the Approved Budget exceeds one
hundred ten percent (110%) of the 7th Floor TI Allowance (as the same may be
adjusted pursuant to the 7th Floor TI Allowance Reallocation Right), then Tenant
shall deposit an amount equal to the 7th Floor Excess Costs with Landlord no
less than ten (10) Business Days before commencing work on the 7th Floor Tenant
Improvements. In such case, Tenant’s funds shall be disbursed by Landlord on a
pari pasu basis with the 7th Floor TI Allowance (as the same may be adjusted
pursuant to the 7th Floor TI Allowance Reallocation Right) as set forth in the
7th Floor Work Letter. Following disbursement of the 7th Floor TI Allowance (as
the same may be adjusted pursuant to the 7th Floor TI Allowance Reallocation
Right) and any Tenant funds deposited with Landlord, Tenant shall pay for all
remaining costs (excluding costs that are Landlord’s obligation under Section
2.3(a) of the 7th Floor Work Letter) for the 7th Floor Tenant Improvements
within ten (10) Business Days after written notice from Landlord of the amount
due from Tenant. At the option of Landlord, amounts payable by Tenant pursuant
to this paragraph shall be paid directly to Tenant’s contractor or such other
party as Landlord may reasonably designate in writing.
(e)    Early Access. Tenant will be granted access to the 7th Floor Premises for
the purpose of constructing the 7th Floor Tenant Improvements and the placement
of personal property in the 7th Floor Premises, provided that prior to entering
upon the 7th Floor Premises, Tenant shall furnish to Landlord evidence
satisfactory to Landlord that insurance coverages required of Tenant under the
provisions of Article 23 of the Existing Lease are in effect. Any such entry
shall be subject to all the terms and conditions of this Lease, provided that
Tenant’s obligation to pay Rent or utilities for the 7th Floor Premises shall
not commence until the 7th Floor Term Commencement Date.
(f)    Selection of Laborers. With respect to the 7th Floor Tenant Improvements,
Landlord and Tenant shall mutually agree upon the selection of the architect,
engineer, general contractor and major subcontractors, and Landlord and Tenant
shall each participate in the review of the competitive bid process. Landlord
shall not unreasonably withhold its consent, but may refuse to approve any
architects, consultants, contractors, subcontractors or material suppliers that
Landlord reasonably believes could cause labor disharmony or may not have
sufficient experience, in Landlord’s reasonable opinion, to perform work in an
occupied Class “A” laboratory research building. Landlord hereby consents to
Tenant engaging Turner Construction Company as the general contractor and SABA
Architects as the architect for the 7th Floor Tenant Improvements, to the extent
Tenant elects to engage such parties in such capacities.
9.Condition of 7th Floor Premises. Tenant acknowledges that (a) it is fully
familiar with the condition of the 7th Floor Premises and agrees to take the
same in its condition “as is” as of the Amendment Execution Date, subject only
to Landlord’s obligations under the Lease (including but not limited to
Landlord’s obligations under this Section 9), and (b) Landlord shall have no
obligation to alter, repair or otherwise prepare the 7th Floor Premises for
Tenant’s occupancy for the 7th Floor Premises Term or to pay for any
improvements to the 7th Floor Premises, except with respect to the 7th Floor TI
Allowance, the 7th Floor Test Fit Allowance and as otherwise expressly stated in
the Lease. Notwithstanding anything to the contrary, at Landlord’s sole cost and
expense, Landlord shall deliver the 7th Floor Premises to Tenant with the work
to be performed by Landlord as described in the attached Exhibit D completed
(the cost of which work shall not be deducted from the 7th Floor TI Allowance or
passed through as an Operating Expense, whether completed before or after Tenant
takes possession of the 7th Floor Premises) (such obligation, “Landlord’s
Delivery Obligation”). Tenant’s taking possession of the 7th Floor Premises
shall, except as otherwise agreed to in writing by Landlord and Tenant,
conclusively establish that the 7th Floor Premises, the Building and the Project
were at such time in good, sanitary and satisfactory condition and repair and
that Landlord’s Delivery Obligation was satisfied; provided that, if Landlord
fails to satisfy Landlord’s Delivery Obligation (a “Delivery Shortfall”), then
Tenant may, as its sole and exclusive remedy, deliver notice of such failure to
Landlord detailing the nature of such failure (a “Shortfall Notice”); provided,
further, that any Shortfall Notice must be received by Landlord no later than
the date (the “Shortfall Notice Deadline”) that is thirty (30) days after the
Amendment Execution Date.  In the event that Landlord receives a Shortfall
Notice on or before the Shortfall Notice Deadline, Landlord shall, at Landlord’s
expense, promptly remedy the Delivery Shortfall. Landlord shall not have any
obligations or liabilities in connection with a failure to satisfy Landlord’s
Delivery Obligation except to the extent such failure is identified by Tenant in
a Shortfall Notice delivered to Landlord on or before the Shortfall Notice
Deadline. Notwithstanding anything to the contrary, Landlord shall deliver the
7th Floor Premises to Tenant free and clear of any Hazardous Materials in
violation of Applicable Laws to the extent in effect and as interpreted and
applied as of the Amendment Execution Date.

10.6th Floor Right of First Offer. Tenant acknowledges that Landlord is in
active negotiations to lease the premises comprising approximately 19,370 square
feet of Rentable Area on the sixth (6th) floor of the Building (the “Active
Negotiation Premises”) to another prospective tenant. Upon the full execution
and delivery of a lease for all of the Active Negotiation Premises with another
prospective tenant, which is the first lease for all of the Active Negotiation
Premises to be executed and delivered after the Amendment Effective Date (the
“Active Negotiations Premises Lease”), then subject and subordinate to any
rights of (a) the tenant under such Active Negotiations Premises Lease, and (b)
any other parties’ pre-existing rights (based on written contracts executed
prior to the Amendment Execution Date), for so long as Tenant continues to lease
and occupy one hundred percent (100%) of both the Premises and the Adjacent
Building Premises, Tenant shall have a continuing right of first offer (“ROFO”)
as to any rentable premises on the sixth (6th) floor of the Building for which
Landlord is seeking a tenant (“Available ROFO Premises”); provided, however,
that in no event shall Landlord be required to lease any Available ROFO Premises
to Tenant for any period past the date on which the Lease expires or is
terminated pursuant to its terms. Notwithstanding the foregoing, to the extent
that Landlord renews or extends a then-existing lease with any then-existing
tenant of any space or enters into a new lease with such then-existing tenant
(including but not limited to the tenant under the Active Negotiations Premises
Lease), the affected space shall not be deemed to be Available ROFO Premises. In
the event Landlord intends to market Available ROFO Premises, Landlord shall
provide written notice thereof to Tenant, which notice shall include the terms
and conditions on which Landlord intends to offer the Available ROFO Premises
(the “Notice of Marketing”).
(a)    Within ten (10) Business Days following its receipt of a Notice of
Marketing, Tenant shall advise Landlord in writing whether Tenant elects to
lease all (not just a portion) of the Available ROFO Premises on the terms and
conditions set forth in the Notice of Marketing. If Tenant fails to notify
Landlord of Tenant’s election within such ten (10) Business Day period, then
Tenant shall be deemed to have elected not to lease the Available ROFO Premises.
(b)    If Tenant timely notifies Landlord that Tenant elects to lease all of the
Available ROFO Premises on the terms and conditions set forth in the Notice of
Marketing, then Landlord shall lease the Available ROFO Premises to Tenant upon
the terms and conditions set forth in the Notice of Marketing.
(c)    If (i) Tenant notifies Landlord that Tenant elects not to lease the
Available ROFO Premises, or (ii) Tenant fails to notify Landlord of Tenant’s
election within the ten (10) Business Day period described above, then Landlord
shall have the right to consummate a lease of the Available ROFO Premises at
base rent and concessions (including without limitation tenant allowances and
brokerage commissions) not less than ninety-five percent (95%) of that stated in
the Notice of Marketing, if applicable. If Landlord fails to so consummate a
lease of the Available ROFO Premises within six (6) months after the date of the
Notice of Marketing, then Landlord must again offer the Available ROFO Premises
to Tenant pursuant to the terms of this Article prior to leasing the Available
ROFO Premises to a third party.
(d)    Notwithstanding anything in this Section to the contrary, Tenant may not
exercise the ROFO during such period of time that Tenant is in default under any
provision of the Lease beyond applicable notice and cure periods. Any attempted
exercise of the ROFO during a period of time in which Tenant is so in default
beyond applicable notice and cure periods shall be void and of no effect. In
addition, Tenant shall not be entitled to exercise the ROFO if Tenant has
defaulted (beyond applicable notice and cure periods) in the performance of
either a material monetary obligation or material non-monetary obligation under
the Lease two (2) or more times during the Term or Option Term (as applicable).
(e)    Notwithstanding anything in this Amendment or the Lease to the contrary,
Tenant shall not assign or transfer the ROFO to a party other than a Tenant’s
Affiliate, either separately or in conjunction with an assignment or transfer of
Tenant’s interest in the Lease, without Landlord’s prior written consent, which
consent Landlord may withhold in its sole and absolute discretion.
(f)    If Tenant exercises the ROFO, Landlord does not guarantee that the
Available ROFO Premises will be available on the anticipated commencement date
for the Lease as to such Premises due to a holdover by the then-existing
occupants of the Available ROFO Premises or for any other reason beyond
Landlord’s reasonable control.
(g)    This ROFO shall remain in effect until the Available ROFO Premises has
been leased by Tenant or a third party, or until the Lease has expired, at which
time this ROFO shall terminate and be of no force and effect. If the Available
ROFO Premises (or any portion thereof) is leased to a third party, and such
third party lease subsequently expires or is otherwise terminated, Tenant’s ROFO
shall be reinstituted.
11.State Tax Incentives. Upon Tenant’s written request, Landlord agrees to
reasonably cooperate with Tenant, at no cost or liability to Landlord, with
respect to Tenant’s application to the Revenue Department for certain tax
benefits pursuant to the Sales Tax Deferral and the application of such benefits
to the construction of the 7th Floor Tenant Improvements, all in accordance with
Article 45 of the Existing Lease.

12.Broker. Each party represents and warrants to the other party that it has not
dealt with any broker or agent in the negotiation for or the obtaining of this
Amendment, other than Flinn Ferguson (“Broker”). Each party agrees to reimburse,
indemnify, save, defend (at the other party’s option and with counsel reasonably
acceptable to the other party) and hold harmless the other party for, from and
against any and all cost or liability for compensation claimed by any such
broker or agent, other than Broker, employed or engaged by the party or claiming
to have been employed or engaged as a result the party’s own acts. Broker is
entitled to a leasing commission in connection with the making of this
Amendment, and Landlord shall pay such commission to Broker pursuant to a
separate agreement between Landlord and Broker.

13.No Default. Tenant represents, warrants and covenants that, to the best of
Tenant’s knowledge, Landlord and Tenant are not in default of any of their
respective obligations under the Existing Lease and no event has occurred that,
with the passage of time or the giving of notice (or both) would constitute a
default by either Landlord or Tenant thereunder. Landlord represents, warrants
and covenants that, to the best of Landlord’s knowledge, Landlord and Tenant are
not in default of any of their respective obligations under the Existing Lease
and no event has occurred that, with the passage of time or the giving of notice
(or both) would constitute a default by either Landlord or Tenant thereunder.

14.Effect of Amendment. Except as modified by this Amendment, the Existing Lease
and all the covenants, agreements, terms, provisions and conditions thereof
shall remain in full force and effect and are hereby ratified and affirmed. In
the event of any conflict between the terms contained in this Amendment and the
Existing Lease, the terms herein contained shall supersede and control the
obligations and liabilities of the parties.

15.Successors and Assigns. Each of the covenants, conditions and agreements
contained in this Amendment shall inure to the benefit of and shall apply to and
be binding upon the parties hereto and their respective heirs, legatees,
devisees, executors, administrators and permitted successors and assigns and
sublessees. Nothing in this section shall in any way alter the provisions of the
Lease restricting assignment or subletting.

16.Miscellaneous. This Amendment becomes effective only upon execution and
delivery hereof by Landlord and Tenant. The captions of the paragraphs and
subparagraphs in this Amendment are inserted and included solely for convenience
and shall not be considered or given any effect in construing the provisions
hereof. All exhibits hereto are incorporated herein by reference. Submission of
this instrument for examination or signature by Tenant does not constitute a
reservation of or option for a lease, and shall not be effective as a lease,
lease amendment or otherwise until execution by and delivery to both Landlord
and Tenant.

17.Authority. Each party guarantees, warrants and represents to the other that
the individual or individuals signing this Amendment on its behalf have the
power, authority and legal capacity to sign this Amendment on behalf of and to
bind all entities, corporations, partnerships, limited liability companies,
joint venturers or other organizations and entities on whose behalf such
individual or individuals have signed.

18.Counterparts; Facsimile and PDF Signatures. This Amendment may be executed in
one or more counterparts, each of which, when taken together, shall constitute
one and the same document. A facsimile or portable document format (PDF)
signature on this Amendment shall be equivalent to, and have the same force and
effect as, an original signature.

plans, drawings, approvals and to sign change orders pursuant to this Work
Letter and (ii) an officer of Landlord as the person authorized to sign any
amendments to this Work Letter or the Lease. Tenant shall not be obligated to

the 7th Floor Tenant Improvements shall provide that Tenant may assign such
contracts and any warranties with respect to the 7th Floor Tenant Improvements

performed by Tenant’s contractor, at Tenant’s sole cost and expense (subject to
Landlord’s obligations with respect to the 7th Floor TI Allowance (as the same
may be adjusted pursuant to the 7th Floor TI Allowance Reallocation Right), the
7th Floor Test Fit Allowance and for costs incurred due to a Change (as defined
below) requested by Landlord under Section 2.3(a) of this Work Letter) in
accordance with the Approved Plans (as defined below), the Lease and this Work
Letter. If Tenant fails to pay, or is late in paying, any sum due to Landlord
under Section 8 of the Lease Amendment or this Work Letter, then Landlord shall
have all of the rights and remedies set forth in the Lease for nonpayment of
Rent (including the right to interest and the right to assess a late charge),
and for purposes of any litigation instituted with regard to such amounts the
same shall be considered Rent. All material and equipment furnished by Tenant or
its contractors as the 7th Floor Tenant Improvements shall be new or “like new;”
the 7th Floor Tenant Improvements shall be performed in a first-class,
workmanlike manner; and the quality of the 7th Floor Tenant Improvements shall
be of a nature and character not less than the Building Standard. Tenant shall
take, and shall require its contractors to take, commercially reasonable steps
to protect the 7th Floor Premises during the performance of any 7th Floor Tenant
Improvements, including covering or temporarily removing any window coverings so
as to guard against dust, debris or damage.

2.1    Work Plans. Tenant shall prepare and submit to Landlord for approval
(such approval to not be unreasonably withheld, conditioned or delayed)
schematics covering the 7th Floor Tenant Improvements prepared in conformity
with the applicable provisions of this Work Letter (the “Draft Schematic
Plans”). The Draft Schematic Plans shall contain sufficient information and
detail to accurately describe the proposed design to Landlord and such other
information as Landlord may reasonably request. Landlord shall notify Tenant in
writing within ten (10) Business Days after receipt of the Draft Schematic Plans
whether Landlord approves or objects to the Draft Schematic Plans and of the
manner, if any, in which the Draft Schematic Plans are unacceptable. Landlord’s
failure to respond within such ten (10) Business Day period shall be deemed
approval by Landlord. If Landlord reasonably objects to the Draft Schematic
Plans, then Tenant shall revise the Draft Schematic Plans and cause Landlord’s
objections to be remedied in the revised Draft Schematic Plans. Tenant shall
then resubmit the revised Draft Schematic Plans to Landlord for approval, such
approval not to be unreasonably withheld, conditioned or delayed. Landlord’s
approval of or objection to revised Draft Schematic Plans and Tenant’s
correction of the same shall be in accordance with this Section until Landlord
has approved the Draft Schematic Plans in writing or been deemed to have
approved them. The iteration of the Draft Schematic Plans that is approved or
deemed approved by Landlord without objection shall be referred to herein as the
“Approved Schematic Plans.”

2.2    Construction Plans. Tenant shall prepare final plans and specifications
for the 7th Floor Tenant Improvements that (a) are consistent with and are
logical evolutions of the Approved Schematic Plans and (b) incorporate any other
Tenant-requested (and Landlord-approved) Changes (as defined below). As soon as
such final plans and specifications (“Construction Plans”) are completed, Tenant
shall deliver the same to Landlord for Landlord’s approval, which approval shall
not be unreasonably withheld, conditioned or delayed. Such Construction Plans
shall be approved or disapproved by Landlord within ten (10) Business Days after
delivery to Landlord. Landlord’s failure to respond within such ten (10)
Business Day period shall be deemed approval by Landlord. If the Construction
Plans are disapproved by Landlord, then Landlord shall notify Tenant in writing
of its objections to such Construction Plans, and the parties shall confer and
negotiate in good faith to reach agreement on the Construction Plans. Promptly
after the Construction Plans are approved by Landlord and Tenant, two (2) copies
of such Construction Plans shall be initialed and dated by Landlord and Tenant,
and Tenant shall promptly submit such Construction Plans to all appropriate
Governmental Authorities for approval. The Construction Plans so approved, and
all change orders specifically permitted by this Work Letter, are referred to
herein as the “Approved Plans.”

2.3    Changes to the 7th Floor Tenant Improvements. Any changes to the Approved
Plans (each, a “Change”) shall be requested and instituted in accordance with
the provisions of this Article 2 and shall be subject to the written approval of
the non-requesting party in accordance with this Work Letter.

(a)Change Request. Either Landlord or Tenant may request Changes after Landlord
approves the Approved Plans by notifying the other party thereof in writing in
substantially the same form as the AIA standard change order form (a “Change
Request”), which Change Request shall detail the nature and extent of any
requested Changes, including (i) the Change, (ii) the party required to perform
the Change and (iii) any modification of the Approved Plans and the Schedule, as
applicable, necessitated by the Change. If the nature of a Change requires
revisions to the Approved Plans, then the requesting party shall be solely
responsible for the cost and expense of such revisions and any increases in the
cost of the 7th Floor Tenant Improvements as a result of such Change; provided
that if Tenant requests the Change, then Tenant may utilize the 7th Floor TI
Allowance (as the same may be adjusted pursuant to the 7th Floor TI Allowance
Reallocation Right). Change Requests shall be signed by the requesting party’s
Authorized Representative.

(b)Approval of Changes. All Change Requests shall be subject to the other
party’s prior written approval, which approval shall not be unreasonably
withheld, conditioned or delayed. The non-requesting party shall have five (5)
Business Days after receipt of a Change Request to notify the requesting party
in writing of the non-requesting party’s decision either to approve or object to
the Change Request. The non-requesting party’s failure to respond within such
five (5) Business Day period shall be deemed approval by the non-requesting
party.

2.4    Preparation of Estimates. Tenant shall, before proceeding with any
Change, using its best efforts, prepare as soon as is reasonably practicable
(but in no event more than seven (7) Business Days after delivering a Change
Request to Landlord or receipt of a Change Request) an estimate of the increased
costs or savings that would result from such Change, as well as an estimate on
such Change’s effects on the Schedule. Landlord shall have five (5) Business
Days after receipt of such information from Tenant to (a) in the case of a
Tenant-initiated Change Request, approve or reject such Change Request in
writing, or (b) in the case of a Landlord-initiated Change Request, notify
Tenant in writing of Landlord’s decision either to proceed with or abandon the
Landlord-initiated Change Request.

3.Completion of 7th Floor Tenant Improvements. Subject to the terms of the Lease
and this Work Letter, Tenant, at its sole cost and expense (except for the 7th
Floor TI Allowance, as the same may be adjusted pursuant to the 7th Floor TI
Allowance Reallocation Right, and the 7th Floor Test Fit Allowance), shall
perform and complete the 7th Floor Tenant Improvements in all respects (a) in
substantial conformance with the Approved Plans, (b) otherwise in compliance
with provisions of the Lease and this Work Letter and (c) in accordance with
Applicable Laws, the requirements of Tenant’s insurance carriers, the
requirements of Landlord’s insurance carriers (to the extent Landlord provides
its insurance carriers’ requirements to Tenant prior to the signing of a
contract with the general contractor) and the board of fire underwriters having
jurisdiction over the 7th Floor Premises. “Substantial Completion” shall be
deemed to have occurred upon Tenant’s providing the following to Landlord:
(i) evidence reasonably satisfactory to Landlord that the 7th Floor Tenant
Improvements have been paid for in full, which shall be evidenced by the
architect’s certificate of completion and the general contractor’s and each
subcontractor’s and material supplier’s final unconditional waivers and releases
of liens, each in a form reasonably acceptable to Landlord; provided, however,
with respect to subcontractors and material suppliers providing less than
$50,000 in the aggregate of labor, materials or services, Tenant shall not be
required to provide lien waivers and releases so long as the total amount of the
unpaid labor, services and materials for all subcontractors for which no lien
releases have been obtained, is less than $50,000 in the aggregate, (ii) a
certificate of occupancy for the 7th Floor Premises issued by the City of
Seattle, if applicable, (iii) a Certificate of Substantial Completion in the
form of the American Institute of Architects document G704 or other reasonable
form, executed by the project architect and the general contractor, (iv) any and
all liens related to the 7th Floor Tenant Improvements have either been
discharged of record (by payment, bond, order of a court of competent
jurisdiction or otherwise) or waived by the party filing such lien, (v) an
affidavit from Tenant’s architect certifying that all work performed in, on or
about the 7th Floor Premises is substantially in accordance with the Approved
Plans, (vi) a complete “as built” drawing print sets, project specifications and
shop drawings and electronic CADD files on disc (showing the 7th Floor Tenant
Improvements as an overlay on the Building “as built” plans, provided that
Landlord provides the Building “as-built” plans to Tenant) of all contract
documents for work performed by their architect and engineers in relation to the
7th Floor Tenant Improvements, (vii) a commissioning report prepared by a
licensed, qualified commissioning agent hired by Tenant and reasonably
acceptable to Landlord for all new or affected mechanical, electrical and
plumbing systems, and (viii) such other “close out” materials as Landlord
reasonably requests consistent with Landlord’s own requirements for its
contractors, such as copies of manufacturers’ warranties, operation and
maintenance manuals and the like.

4.Insurance.

4.1    Property Insurance. At all times during the period beginning with
commencement of construction of the 7th Floor Tenant Improvements and ending
with final completion of the 7th Floor Tenant Improvements, Tenant shall
maintain, or cause to be maintained (in addition to the insurance required of
Tenant pursuant to the Lease), property insurance coverage with respect to the
general contractor’s and any subcontractors’ machinery, tools and equipment.
Coverage shall be carried on a primary basis by such general contractor or the
applicable subcontractor(s). Tenant agrees to pay any deductible, and Landlord
is not responsible for any deductible, for a claim under such insurance, except
to the extent caused by Landlord’s negligence or intentional misconduct. Tenant
shall use reasonable efforts to require that such property insurance shall
contain an express waiver of any right of subrogation by the insurer against
Landlord and the Landlord Parties, and shall name Landlord and its affiliates as
loss payees as their interests may appear.

4.2    Workers’ Compensation Insurance. At all times during the period of
construction of the 7th Floor Tenant Improvements, Tenant shall, or shall cause
its contractors or subcontractors to, maintain statutory workers’ compensation
insurance as required by Applicable Laws.

5.Liability. Except to the extent caused by Landlord’s negligence or intentional
misconduct or covered by property insurance actually carried by Landlord (or
that would have been covered by Landlord’s property insurance had Landlord
carried the property insurance required under the Lease), Tenant assumes sole
responsibility and liability for any and all injuries or the death of any
persons, including Tenant’s contractors and subcontractors and their respective
employees, agents and invitees, and for any and all damages to property caused
by, resulting from or arising out of any act or omission on the part of Tenant,
Tenant’s contractors or subcontractors, or their respective employees, agents
and invitees in the prosecution of the 7th Floor Tenant Improvements. Tenant
agrees to indemnify, save, defend (at Landlord’s option and with counsel
reasonably acceptable to Landlord) and hold the Landlord Indemnitees harmless
from and against all Claims due to, because of or arising out of any and all
such injuries, death or damage, whether real or alleged, and Tenant and Tenant’s
contractors and subcontractors shall assume and defend at their sole cost and
expense all such Claims; provided, however, that nothing contained in this Work
Letter shall be deemed to indemnify or otherwise hold Landlord harmless from or
against liability to the extent caused by Landlord’s negligence or willful
misconduct. Any deficiency in design or construction of the 7th Floor Tenant
Improvements shall be solely the responsibility of Tenant, notwithstanding the
fact that Landlord may have approved of the same in writing.

6.TI Allowance.

6.1    Application of 7th Floor Test Fit Allowance and 7th Floor TI Allowance.
Landlord shall contribute the 7th Floor Test Fit Allowance towards the cost of a
test fit plan for the 7th Floor Premises, and Landlord shall contribute the 7th
Floor TI Allowance toward the costs and expenses incurred in connection with the
performance of the 7th Floor Tenant Improvements, all in accordance with Section
8 of the Lease Amendment and this Work Letter. If the entire 7th Floor Test Fit
Allowance is not applied toward the cost of the test fit plan, or if the entire
7th Floor TI Allowance (as the same may be adjusted pursuant to the 7th Floor TI
Allowance Reallocation Right) is not applied toward or reserved for the costs of
the 7th Floor Tenant Improvements, then Tenant shall not be entitled to a credit
of such unused portion of the 7th Floor Test Fit Allowance or the 7th Floor TI
Allowance. Tenant may apply the 7th Floor Test Fit Allowance for the payment of
the test fit plan costs and may apply the 7th Floor TI Allowance for the payment
of construction and other costs, in accordance with the terms and provisions of
the Lease Amendment and this Work Letter.

6.2    Approval of Budget for the 7th Floor Tenant Improvements. Notwithstanding
anything to the contrary set forth elsewhere in this Work Letter or the Lease,
Landlord shall not have any obligation to expend any portion of the 7th Floor TI
Allowance until Landlord and Tenant shall have approved in writing the budget
for the 7th Floor Tenant Improvements (the “Approved Budget”). Prior to
Landlord’s approval of the Approved Budget, Tenant shall pay all of the costs
and expenses incurred in connection with the 7th Floor Tenant Improvements as
they become due. Subject to Landlord’s obligations under Section 2.3(a) of this
Work Letter regarding costs incurred with respect to any Change requested by
Landlord, Landlord shall not be obligated to reimburse Tenant for costs or
expenses relating to the 7th Floor Tenant Improvements that exceed the amount of
the 7th Floor TI Allowance (as the same may be adjusted pursuant to the 7th
Floor TI Allowance Reallocation Right). Landlord shall not unreasonably
withhold, condition or delay its approval of any budget for the 7th Floor Tenant
Improvements that is proposed by Tenant.

6.3    Fund Requests.

(a)    7th Floor Test Fit Allowance. Upon submission by Tenant to Landlord of an
itemized invoice for the test fit plan costs, then Landlord shall, within thirty
(30) days following receipt of such invoice, pay to the applicable architect the
amount of the test fit plan costs, up to the amount of the 7th Floor Test Fit
Allowance.
(b)    7th Floor TI Allowance. Tenant may periodically (but no more frequently
than monthly) submit written requests for disbursements of the 7th Floor TI
Allowance. Each request for funding (a “Fund Request”) shall include the
following: (i) the total amount of the 7th Floor TI Allowance requested, (ii) a
summary of the 7th Floor Tenant Improvements performed using AIA standard form
Application for Payment (G 702) executed by the general contractor and by the
architect or other reasonable form, (iii) invoices from the general contractor,
the architect, and any subcontractors, material suppliers and other parties
requesting payment with respect to the amount of the 7th Floor TI Allowance then
being requested, (iv) unconditional lien releases from the general contractor
and each subcontractor and material supplier with respect to previous payments
made by either Landlord or Tenant for the 7th Floor Tenant Improvements in a
form reasonably acceptable to Landlord and complying with Applicable Laws and
(v) conditional lien releases from the general contractor and each subcontractor
and material supplier with respect to the 7th Floor Tenant Improvements
performed that correspond to the Fund Request, each in a form reasonably
acceptable to Landlord and complying with Applicable Laws; provided, however,
for purposes of clauses (iv) and (v) above, with respect to subcontractors and
material suppliers providing less than $50,000 in the aggregate of labor,
materials or services, Tenant shall not be required to provide lien releases so
long as the total amount of the unpaid labor, services and materials for all
subcontractors for which no lien releases have been obtained, is less than
$50,000 in the aggregate. Within thirty (30) days following receipt by Landlord
of a Fund Request and the accompanying materials required by this Section,
Landlord shall pay to (as elected by Tenant) the applicable contractors,
subcontractors and material suppliers or Tenant the amount of 7th Floor Tenant
Improvement costs set forth in such Fund Request; provided, however, that
Landlord shall not be obligated to make any payments under this Section until
the budget for the 7th Floor Tenant Improvements is approved in accordance with
Section 6.2, and any Fund Request under this Section shall be subject to the
payment limits set forth in Section 6.2 above and Section 8 of the Lease
Amendment.
6.4    Accrual Information. In addition to the other requirements of this
Section 6, Tenant shall, no more often than once every calendar quarter during
construction of the 7th Floor Tenant Improvements, provide Landlord with a
written summary of all work performed by Tenant or its agents, employees or
contractors for which a Fund Request has not yet been issued to Landlord,
including the following: the amount that Tenant will seek from Landlord related
to such work and the dates on which such work was performed. Such information
shall be provided to Landlord within ten (10) Business Days after Landlord’s
request therefor.

7.Miscellaneous.

7.1    Incorporation of Lease Provisions. Sections 17.1 through 17.3, Section
17.5, Sections 17.7 through 17.10, and Sections 40.6 through 40.20 of the
Existing Lease are incorporated into this Work Letter by reference, and shall
apply to this Work Letter in the same way that they apply to the Lease.

7.2    General. Except as otherwise set forth in the Lease Amendment or this
Work Letter, this Work Letter shall not apply to improvements performed in any
additional premises added to the Premises at any time or from time to time,
whether by any options under the Lease or otherwise; or to any portion of the
Premises or any additions to the Premises in the event of a renewal or extension
of the original Term, whether by any options under the Lease or otherwise,
unless the Lease or any amendment or supplement to the Lease expressly provides
that such additional premises are to be delivered to Tenant in the same
condition as the 7th Floor Premises.

into as of this 27th day of June, 2016, by and between BMR-500 FAIRVIEW AVENUE
LLC, a Delaware limited liability company (“Landlord”), and NANOSTRING
TECHNOLOGIES, INC., a Delaware corporation (“Tenant”), and is attached to and
made a part of that certain First Amendment to Lease dated of even date herewith
(the “Lease Amendment”), by and between Landlord and Tenant, which amends that
certain Lease dated as of December 22, 2014 (as amended by the Lease Amendment,
and as the same may be further amended, amended and restated, supplemented or
otherwise modified from time to time, the “Lease”), by and between Landlord and
Tenant, for the Premises located at 500 Fairview Avenue North, Seattle,
Washington 98109. All capitalized terms used but not otherwise defined herein
shall have the meanings given them in the Lease Amendment.
RECITALS
A.WHEREAS, pursuant to the Lease Amendment, Landlord has agreed to contribute a
tenant improvement allowance in the amount of Two Million Four Hundred Seventy
Two Thousand Nine Hundred Eighty and 15/100 Dollars ($2,472,980.15) (the “7th
Floor TI Allowance”) to be used for the construction of certain tenant
improvements (the “7th Floor Tenant Improvements”) in the 7th Floor Premises by
Tenant; and

B.WHEREAS, pursuant to the Lease, Landlord has agreed to contribute a tenant
improvement allowance in the amount of Two Million Five Hundred Ninety Thousand
Five Hundred Ten and No/100 Dollars ($2,590,510.00) (the “Original Premises TI
Allowance”) to be used for the construction of certain tenant improvements (the
“Original Premises Tenant Improvements”) in the Original Premises by Tenant; and

C.WHEREAS, Tenant has requested, and Landlord has agreed to grant to Tenant, the
7th Floor TI Allowance Reallocation Right (as defined below), on the terms and
conditions set forth in the Lease Amendment and in this Agreement.
D.

AGREEMENT
NOW, THEREFORE, Landlord and Tenant, in consideration of the Recitals set forth
above which are incorporated herein by this reference, and in consideration of
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.Reallocation of TI Allowance. If the cost of the 7th Floor Tenant Improvements
exceeds the amount of the 7th Floor TI Allowance, then Tenant shall have the
right (the “7th Floor TI Allowance Reallocation Right”) to reallocate all or a
portion of any unused Original Premises TI Allowance to pay such excess cost of
the 7th Floor Tenant Improvements up to three (3) times (subject to the
limitations set forth in the Lease and this Agreement), provided, however, that
all of the following conditions must be satisfied at the time that Tenant
exercises the 7th Floor TI Allowance Relocation Right:

(a)Tenant shall have expended all of the 7th Floor TI Allowance;

(b)No later than the TI Deadline for the Original Premises TI Allowance, Tenant
shall have delivered to Landlord a written request to reallocate a portion of
the unused Original Premises TI Allowance to pay the remaining cost to complete
the construction of the 7th Floor Tenant Improvements, setting forth the amount
of the Original Premises TI Allowance that Tenant desires to reallocate (the
“7th Floor Reallocated TI Allowance Amount”); and

(c)Tenant shall not be in default beyond any applicable notice and cure periods
under the Lease.

2.Effect of 7th Floor TI Allowance Reallocation. Immediately upon Tenant’s
exercise of the 7th Floor TI Allowance Reallocation Right in accordance with
Section 1 above, (a) the Original Premises TI Allowance shall be reduced by the
7th Floor Reallocated TI Allowance Amount, and Landlord shall have no further
obligation to fund the 7th Floor Reallocated TI Allowance Amount for the
performance of the Original Premises Tenant Improvements, and (b) the 7th Floor
TI Allowance shall be increased by the 7th Floor Reallocated TI Allowance
Amount, and Landlord shall be obligated to disburse the 7th Floor Reallocated TI
Allowance Amount to pay the cost of the 7th Floor Tenant Improvements in
accordance with and subject to the limitations of the Lease Amendment and this
Agreement.

3.Time of the Essence. Time shall be of the essence with respect to Tenant’s
exercise of the 7th Floor TI Allowance Reallocation Right. Tenant acknowledges
that it would be inequitable to require Landlord to allow any reallocation of
the Original Premises TI Allowance after the TI Deadline for the Original
Premises TI Allowance. The period of time within which Tenant may exercise the
7th Floor TI Allowance Reallocation Right shall not be extended or enlarged by
reason of Tenant’s inability to exercise the 7th Floor TI Allowance Reallocation
Right due to a failure of any of the conditions set forth in Section 1 above.

4.TI Deadline. Landlord and Tenant hereby acknowledge that the TI Deadline for
the Original Premises TI Allowance is February 12, 2017.

5.Incorporation of Lease Provisions. Sections 40.6 through 40.19 of the Existing
Lease are incorporated into this Agreement by reference, and shall apply to this
Agreement in the same way that they apply to the Lease.
