 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.      Extension Term. The Term shall be extended by a period of thirty-six (36) months. Accordingly, the Term Expiration Date is hereby changed to January 31, 2020. The period from February 1, 2017 (the “Initial Extension Term Commencement Date”)
to January 30, 2020 is referred to herein as the “Initial Extension Term”. The parties acknowledge and agree that the Initial Extension Term is not established pursuant to an Option (as described in
Section 41 of the Existing Lease) and that Tenant shall continue to have two (2) Options to extend the Term by three (3) years each beyond the Initial Extension Term, in accordance with
Section 41 of the Existing Lease. 












 3.      Condition of Premises, Tenant
acknowledges that (a) it is in possession of and is fully familiar with the condition of the Premises and, notwithstanding anything contained in the Lease to the contrary, agrees to take the same in its condition “as is”
as of the first day of the Initial Extension Term, and (b) Landlord shall have no obligation to alter, repair or otherwise prepare the Premises for Tenant’s continued occupancy for the Initial Extension Term or to pay for any
improvements to the Premises, except for the Extension TI Allowance, as described below. 

4.      Extension Improvements. Landlord shall make available to Tenant a tenant
improvement allowance not to exceed Two Hundred Forty-Six Thousand Eight Hundred Eighty-Five Dollars ($246,885) (based upon Fifteen Dollars ($15.00) per square foot of rentable area in the Premises) (the
“Extension TI Allowance”) to cause appropriate improvements to be constructed in the Premises (the “Extension Improvements”). Tenant shall cause the Extension Improvements to be constructed in the Premises pursuant
to the Work Letter attached hereto as Exhibit A (the “Work Letter”) at a cost to Landlord not to exceed the Extension TI Allowance. 

(a)      The Extension TI Allowance may be applied to the costs of (a) construction, (b)
project review by Landlord (which fee shall equal three percent (3%) of the cost of the Extension Improvements, including the Extension TI Allowance), (c) to the extent applicable, commissioning of mechanical, electrical and plumbing systems by a
licensed, qualified commissioning agent hired by Tenant and approved by Landlord, (d) space planning, architect, engineering and other related services performed by third parties unaffiliated with Tenant, (e) building permits and other
taxes, fees, charges and levies by applicable governmental authorities for permits or for inspections of the Extension Improvements, and (f) costs and expenses for labor, material, equipment and fixtures. In no event shall the Extension TI
Allowance be used for (v) the cost of work that is not approved in writing by Landlord, (w) payments to Tenant or any affiliates of Tenant, (x) 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 this Lease or (z) costs that are recoverable by Tenant from a third party (e.g., insurers,
warrantors, or tortfeasors). 
 (b)      Tenant shall have until January 31, 2018 (the
“Extension TI Deadline”), to submit a Fund Request (as defined in Section 6.3 of the Work Letter) for the unused portion of the Extension TI Allowance, after which date Landlord’s obligation to fund
such costs shall expire. 
 (c)      In no event shall any unused Extension TI Allowance
entitle Tenant to a credit against Rent payable under this Lease. Tenant shall deliver to Landlord (a) if required by the scope of worked included as part of the Extension Improvements, a certificate of occupancy for the Premises suitable for
the Permitted Use and (b) a Certificate of Substantial Completion in the form of the American Institute of Architects document G704, executed by the project architect and the general contractor. The term “Substantially
Complete” or “Substantial Completion” means that the Extension Improvements are substantially complete in accordance with the Approved Plans (as defined in the Work Letter), except for minor punch list items. 

(d)      Prior to performing the Extension Improvements in the Premises, Tenant shall furnish to
Landlord evidence satisfactory to Landlord that insurance coverages required of Tenant under the provisions of Article 23 of the Lease are in effect, and Tenant’s construction of the Extension Improvements shall be subject to all the
terms and conditions of the Lease. 

  
 2 













 (e)      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 may refuse to use any architects, consultants,
contractors, subcontractors or material suppliers that Landlord reasonably believes could cause labor disharmony. Landlord hereby approves the use by Tenant of R.E. Dinneen Architects & Planners, Inc. as Tenant’s architect for the
Extension Improvements. For the avoidance of doubt, Tenant can seek approval of alternate architects as well. 

5.      Base Rent. Notwithstanding anything to the contrary in the Lease, from and after
the Initial Extension Term Commencement Date, Tenant shall pay to Landlord as Base Rent for the Premises the applicable amounts set forth in the chart below:

 EXHIBIT A 

WORK LETTER 

This Work Letter (this “Work Letter”) is made and entered into as of the 19th day of April, 2016, by
and between BMR-134 COOLIDGE AVENUE LLC, a Delaware limited liability company (“Landlord”), and TARVEDA THERAPEUTICS, INC. (formerly known as Blend Therapeutics, Inc.), a Delaware corporation
(“Tenant”), and is attached to and made a part of that certain Third Amendment to Lease dated as of April             , 2016 (the “Third
Amendment”), which amends that certain Lease dated as of December 12, 2011, as amended by that certain First Amendment to Lease dated as of February 23, 2012 and that certain Second Amendment to Lease dated as of January 8,
2013 (collectively, and as the same may be 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 134 Coolidge Avenue in
Watertown, Massachusetts. All capitalized terms used but not otherwise defined herein shall have the meanings given them in the Lease. 

1.        General Requirements. 

1.1.      Authorized Representatives. 

(a)      Landlord designates, as Landlord’s authorized representative
(“Landlord’s Authorized Representative”), (i) Sal Zinno as the person authorized to initial 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 respond to or act upon any such item until such item has been initialed or signed (as applicable) by the appropriate Landlord’s Authorized
Representative. Landlord may change either Landlord’s Authorized Representative upon one (1) business day’s prior written notice to Tenant. 

(b) Tenant designates Sudha Kadiyala (“Tenant’s Authorized Representative”) as the person authorized to
initial and sign all plans, drawings, change orders and approvals pursuant to this Work Letter. Landlord shall not be obligated to respond to or act upon any such item until such item has been initialed or signed (as applicable) by Tenant’s
Authorized Representative. Tenant may change Tenant’s Authorized Representative upon one (1) business day’s prior written notice to Landlord. 

1.2.      Schedule. The schedule for design and development of the Extension
Improvements, including the time periods for preparation and review of construction documents, approvals and performance, shall be in accordance with a schedule to be prepared by Tenant (the “Schedule”). Tenant shall prepare the
Schedule so that it is a reasonable schedule for the completion of the Extention Improvements. The Schedule shall clearly identify all activities requiring Landlord participation, including specific dates and time periods when Tenant’s
contractor will require access to areas of the Project outside of the Premises. As soon as the Schedule is completed, Tenant shall deliver the same to Landlord for Landlord’s approval, which approval shall not be unreasonably withheld,
conditioned or delayed. Such Schedule 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 Landlord disapproves the Schedule, then Landlord shall notify Tenant in
writing of its objections to such Schedule, and the parties shall confer and negotiate in good faith to reach agreement on the Schedule. The Schedule shall be subject to adjustment as mutually agreed upon in writing by the parties, or as provided in
this Work Letter. 
 1.3.      Tenant’s Architects, Contractors and Consultants.
The architect, engineering consultants, design team, general contractor and subcontractors responsible for the construction of the Extension Improvements shall be selected by Tenant and approved by Landlord, which approval Landlord shall not
unreasonably withhold, condition or delay. Landlord may refuse to use any architects, consultants, contractors, subcontractors or material suppliers that Landlord reasonably believes could cause labor disharmony. All Tenant contracts related to the
Extension Improvements shall provide that Tenant may assign such contracts and any warranties with respect to the Extension Improvements to Landlord at any time. 

2.      Extension Improvements. All Extension Improvements shall be performed by Tenant’s
contractor, at Tenant’s sole cost and expense (subject to Landlord’s obligations with respect to any portion of the Extension TI Allowance) and in accordance with the Approved Plans (as defined below), the Lease and this Work Letter. To
the extent that the total projected cost of the Extension Improvements (as projected by Landlord) exceeds the Extension TI Allowance (such excess, the “Excess TI Costs”), Tenant shall pay the costs of the Extension Improvements on a
part passu basis with Landlord as such costs become due, in the proportion of Excess TI Costs payable by Tenant to the Extension TI Allowance payable by Landlord. If the cost of the Extension Improvements (as projected by Landlord) increases over
Landlord’s initial projection, then Landlord may notify Tenant and Tenant shall deposit any additional Excess TI Costs with Landlord in the same way that Tenant deposited the initial Excess TI Costs. If Tenant fails to pay, or is late in
paying, any sum due to Landlord under 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 Extension Improvements shall be new or “like new;” the Extension
Improvements shall be performed in a first-class, workmanlike manner; and the quality of the Extension 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 Premises during the performance of any Extension Improvements, including covering or temporarily removing any window coverings so as to guard against dust, debris or damage. All Extension Improvements
shall be performed in accordance with Article 17 of the Lease; provided that, notwithstanding anything in the Lease or this Work Letter to the contrary, in the event of a conflict between this Work Letter and Article 17 of the
Lease, the terms of this Work Letter shall govern. 
 2.1.      Work Plans. Tenant
shall prepare and submit to Landlord for approval schematics covering the Extension 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
Extension 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. All such Construction Plans
shall be submitted by Tenant to Landlord in electronic .pdf, CADD and full-size hard copy formats, and shall be approved or disapproved by Landlord within ten (10) business days after delivery to
Landlord. At the time of approval of the Construction Plans Landlord shall identify any portions of the Extension Improvements that Landlord will require to be removed at the Term Expiration Date or earlier termination of the Lease. Landlord’s
failure to respond within such ten (10) business day period shall be deemed approval by Landlord, and shall also be deemed an acknowledgment that no portion of the Extension Improvements will be require to be removed at the Term Expiration Date
or earlier termination of the Lease. 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 Extension Improvements. Any changes to the Approved Plans (each,
a “Chance”) 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 (a) the Change, (b) the party required to perform the Change and (c) 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 Extension Improvements













 
as a result of such Change. 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 five (5) 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 of 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. 
 2.5.      Quality Control Program: Coordination. Tenant shall provide
Landlord with information regarding the following (together, the “QCP”): (a) Tenant’s general contractor’s quality control program and (b) evidence of subsequent monitoring and action plans. The QCP shall be subject
to Landlord’s reasonable review and approval and shall specifically address the Extension Improvements. Tenant shall ensure that the QCP is regularly implemented on a scheduled basis and shall provide Landlord with reasonable prior notice and
access to attend all inspections and meetings between Tenant and its general contractor. At the conclusion of the Extension Improvements, Tenant shall deliver the quality control log to Landlord, which shall include all records of quality control
meetings and testing and of inspections held in the field, including inspections relating to concrete, steel roofing, piping pressure testing and system commissioning. 

3.      Completion of Extension Improvements. Tenant, at its sole cost and expense (except for the
Extension TI Allowance and any Landlord requested Change) shall perform and complete the Extension 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) and the board of fire underwriters having jurisdiction over the Premises. The Extension Improvements shall be deemed completed at such time as Tenant shall furnish to Landlord (t) evidence satisfactory to Landlord that
(i) all Extension Improvements have been completed and 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 acceptable to Landlord and complying with Applicable Laws, and a Certificate of Substantial Completion in the form of the American Institute of Architects document G704, executed by
the project architect and the general contractor, together with a statutory notice of substantial completion from the general contractor), (ii) all 












 
Extension Improvements have been accepted by Landlord, (iii) any and all liens related to the Extention 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 and (iv) no security interests relating to the Extension Improvements are outstanding, (u) all certifications and approvals with respect to the Extension
Improvements that may be required from any Governmental Authority and any board of fire underwriters or similar body for the use and occupancy of the Premises (including, if applicable, a certificate of occupancy for the Premises for the Permitted

Plans, (x) complete “as built” drawing print sets, project specifications and shop drawings and electronic CADD files on disc (showing the Extension Improvements as an overlay on the Building “as built” plans
(provided that Landlord provides the Building “as-built” plans provided to Tenant) of all contract documents for work performed by their architect and engineers in relation to the
Extension Improvements, (y) a commissioning report prepared by a licensed, qualified commissioning agent hired by Tenant and approved by Landlord for all new or affected mechanical, electrical and plumbing systems (which report Landlord may
hire a licensed, qualified commissioning agent to peer review, and whose reasonable recommendations Tenant’s commissioning agent shall perform and incorporate into a revised report) and (z) 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 Extension Improvements and ending with final completion of the Extension Improvements, Tenant shall maintain, or cause to be maintained (in addition to the insurance required of Tenant pursuant to the Lease), property
insurance insuring Landlord and the Landlord Parties, as their interests may appear. Such policy shall, on a completed values basis for the full insurable value at all times, insure against loss or damage by fire, vandalism and malicious mischief
and other such risks as are customarily covered by the so-called “broad form extended coverage endorsement” upon all Extension Improvements and the general contractor’s and any
subcontractors’ machinery, tools and equipment, all while each forms a part of, or is contained in, the Extension Improvements or any temporary structures on the Premises, or is adjacent thereto; provided that, for the avoidance Of
doubt, insurance coverage with respect to the general contractor’s and any subcontractors’ machinery, tools and equipment 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. 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 Extension Improvements, Tenant shall, or shall cause its contractors or subcontractors to, maintain statutory workers’ compensation insurance as required by Applicable Laws. 












 5.        Liability. 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 Extension 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 caused by Landlord’s negligence or willful misconduct. Any deficiency in design or construction of the Extension Improvements shall be solely the responsibility of
Tenant, notwithstanding the fact that Landlord may have approved of the same in writing. 

6.        Extension TI Allowance. 

6.1.      Application of Extension TI Allowance. Landlord shall contribute the Extension
TI Allowance toward the costs and expenses incurred in connection with the performance of the Extension Improvements, in accordance with Article 4 of the Third Amendment to Lease. If the entire Extension TI Allowance is not applied toward or
reserved for the costs of the Extension Improvements, then Tenant shall not be entitled to a credit of such unused portion of the Extension TI Allowance. If the entire Excess TI Costs advanced by Tenant to Landlord are not applied toward the costs
of the Extension Improvements, then Landlord shall promptly return such excess to Tenant following completion of the Extension Improvements. Tenant may apply the Extension TI Allowance for the payment of construction and other costs in accordance
with the terms and provisions of the Lease. 
 6.2.      Approval of Budget for the
Extension 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 Extension TI Allowance until Landlord and Tenant shall
have approved in writing the budget for the Extension Improvements (the “Approved Budget”). Prior to Landlord’s approval of the Approved Budget, Tenant shall pay all of the costs arid expenses incurred in connection with the
Extension Improvements as they become due. Landlord shall not be obligated to reimburse Tenant for costs or expenses relating to the Extension Improvements that exceed the amount of the Extension TI Allowance. Landlord shall not unreasonably
withhold, condition or delay its approval of any budget for Extension Improvements that is proposed by Tenant. 

6.3.      Fund Requests. Upon submission by Tenant to Landlord of (a) a statement (a
“Fund Request”) setting forth the total amount of the Extension TI Allowance requested, (b) a summary of the Extension Improvements performed using AIA standard form Application for Payment (G 702) executed by the general
contractor and by the architect, (c) invoices from the general contractor, the architect, and any subcontractors, material suppliers and other parties requesting payment with respect to the amount of the Extension TI Allowance then being
requested, and (d) except with respect to the final Fund Request, conditional lien releases from the general contractor and each subcontractor and material supplier with respect to the Extension Improvements













 
performed that correspond to the Fund Request each in a form acceptable to Landlord and complying with Applicable Laws, then Landlord shall, within thirty (30) days following receipt by
Landlord of a Fund Request and the accompanying materials required by this Section, pay to (as elected by Landlord) the applicable contractors, subcontractors and material suppliers or Tenant (for reimbursement for payments made by Tenant to such
contractors, subcontractors or material suppliers either prior to Landlord’s approval of the Approved TI Budget or as a result of Tenant’s decision to pay for the Extension Improvements itself and later seek reimbursement from Landlord in
the form of one lump sum payment in accordance with the Lease and this Work Letter), the amount of Extension Improvement costs set forth in such Fund Request or Landlord’s pari passu share thereof if Excess TI Costs exist based on the Approved
Budget; provided, however, that Landlord shall not be obligated to make any payments under this Section until the budget for the Extension 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 Article 4 of the Lease. Notwithstanding anything in this Section to the contrary, Tenant shall not submit a Fund Request
more often than every thirty (30) days. Any additional Fund Requests submitted by Tenant shall be void and of no force or effect.
