B.WHEREAS, Tenant desires to lease additional premises from Landlord in the Building’s vivarium; 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.Eighth Additional Vivarium Premises.  Effective as of the Twelfth Amendment Execution Date, Landlord hereby leases to Tenant, and Tenant hereby leases from Landlord, approximately one thousand two hundred seventeen (1,217) aggregate additional square feet of Rentable Area located collectively in Room 143 (consisting of approximately five hundred forty-seven (547) square feet of Rentable Area) and Room 154 (consisting of approximately six hundred seventy (670) square feet of Rentable Area) of the Vivarium, as shown on Exhibit A attached hereto (collectively, the “Eighth Additional Vivarium Premises”), for use by Tenant in accordance with the Permitted Use and in accordance with all other terms and conditions of the Lease.  From and after the Twelfth Amendment Execution Date, the term “Premises,” as used in the Lease shall mean the Existing Premises plus the Eighth Additional Vivarium Premises, and the term “Tenant’s Vivarium Space,” as used in the Lease, shall mean the Tenant’s Existing Vivarium Space plus the Eighth Additional Vivarium Premises. 
3.Eighth Additional Vivarium Term.  The Term of the Lease with respect to the Eighth Additional Vivarium Premises (as the same may be earlier terminated in accordance with the Lease, the “Eighth Additional Vivarium Term”) shall commence on the Twelfth Amendment Execution Date and shall expire on the Term Expiration Date.  Failure by Tenant to obtain validation by any medical review board or other similar governmental licensing of the Eighth Additional Vivarium Premises required for the Permitted Use by Tenant shall not serve to extend the commencement of the Eighth Additional Vivarium Term.
4.Condition of Eighth Additional Vivarium Premises.  Tenant acknowledges that neither Landlord nor any agent of Landlord has made any representation or warranty with respect to the condition of the Eighth Additional Vivarium Premises or with respect to the suitability of the Eighth Additional Vivarium Premises for the conduct of Tenant’s business.  Tenant acknowledges that (a) it is fully familiar with the condition of the Eighth Additional Vivarium Premises and agrees to take the same in its condition “as is” as of the Twelfth Amendment Execution Date and (b) Landlord shall have no obligation to alter, repair or otherwise prepare the Eighth Additional Vivarium Premises for Tenant’s occupancy or to pay for or construct any improvements to the Eighth Additional Vivarium Premises.  Tenant’s taking of possession of the Eighth Additional Vivarium Premises shall, except as otherwise agreed to in writing by Landlord and Tenant, conclusively establish that the Eighth Additional Vivarium Premises were at such time in good, sanitary and satisfactory condition and repair.
5.Base Rent and Additional Rent.  In addition to all Base Rent for the Existing Premises, commencing on the Twelfth Amendment Execution Date and continuing for the duration of the Eighth Additional Vivarium Term, Tenant shall pay to Landlord (in accordance with the provisions of the Lease) Base Rent for the Eighth Additional Vivarium Premises.  Base Rent (including the monthly installments of Base Rent) for the Eighth Additional Vivarium Premises shall equal the applicable amounts set forth on Exhibit B attached hereto.  In addition to all Additional Rent for the Existing Premises, commencing as of the Twelfth Amendment Execution Date and continuing for the duration of the Eighth Additional Vivarium Term, Tenant shall pay to Landlord Additional Rent (as defined in (and in accordance with the provisions of) the Lease) with respect to the Eighth Additional Vivarium Premises.

​



6.Pro Rata Share.  Tenant’s Pro Rata Share of the Project with respect to the Eighth Additional Vivarium Premises shall be 0.80%.  Therefore, commencing as of the Twelfth Amendment Execution Date, Tenant’s Pro Rata Share of the Project for the entire Premises (i.e., the Existing Premises plus the Eighth Additional Vivarium Premises) shall be 75.24%.
7.Termination Option.  Notwithstanding anything to the contrary in the Lease, Tenant shall have the right to terminate the Lease, but only with respect to the Eighth Additional Vivarium Premises (and no less than all of the Eighth Additional Vivarium Premises), by providing written notice (the “Eighth Additional Vivarium Termination Notice”) to Landlord at least sixty (60) days prior to Tenant’s desired termination date (the “Eighth Additional Vivarium Termination Date”), which Eighth Additional Vivarium Termination Date shall be set forth in the Eighth Additional Vivarium Termination Notice.  Subject to (a) Landlord’s timely receipt of the Eighth Additional Vivarium Termination Notice and (b) Tenant surrendering the Eighth Additional Vivarium Premises in the condition required under the Lease (including, without limitation, Section 18.2 and Article 26 of the Lease), then, as of the Eighth Additional Vivarium Termination Date, the Lease with respect to the Eighth Additional Vivarium Premises only shall terminate and be of no further force or effect, and Landlord and Tenant shall be relieved of their respective obligations under the Lease with respect to the Eighth Additional Vivarium Premises only from and after the Eighth Additional Vivarium Termination Date, except with respect to those obligations set forth in the Lease that expressly survive the expiration or earlier termination thereof, including payment by Tenant of all amounts owed by Tenant pursuant to the Lease with respect to the Eighth Additional Vivarium Premises for the period up to and including the Eighth Additional Vivarium Termination Date.  The termination right granted to Tenant pursuant to this Section shall automatically terminate and be of no further force or effect in the event that (y) Tenant assigns, subleases or otherwise Transfers the Eighth Additional Vivarium Premises or any portion thereof to other entities or persons, other than in connection with an Exempt Transfer (or in connection with any sublease approved by Landlord pursuant to Article 29 of the Lease), or (z) Tenant’s right to possession of the Eighth Additional Vivarium Premises has previously been terminated.  The termination right granted to Tenant pursuant to this Section is personal to Omeros Corporation, a Washington corporation (“Omeros”) and any Permitted Transferees of Omeros, and may not be exercised by any other assignee, sublessee or transferee of Tenant’s or a Permitted Transferee’s interest in the Lease.
8.Prior Amendment Cleanup.  In Section 6 of the Eighth Amendment, the term “Eighth Amendment Vivarium Premises” is hereby modified to be (and shall be deemed to have always been) “Fifth Additional Vivarium Premises.”  In Section 6 of the Ninth Amendment, the term “Ninth Amendment Vivarium Premises” is hereby modified to be (and shall be deemed to have always been) “Sixth Additional Vivarium Premises.”
9.Eleventh Amendment Expansion Premises.  Effective as of the Twelfth Amendment Execution Date, the last sentence of Section 2 of the Eleventh Amendment is hereby deleted in its entirety and replaced with the following; provided, however, that the term “Existing Premises” as used in the following sentence shall include both the Existing Premises (as defined in the Eleventh Amendment) and the Eighth Additional Vivarium Premises:

​



“From and after the Expansion Premises Term Commencement Date, (a) the term “Premises” as used in the Lease shall include both the Existing Premises and the Expansion Premises, (b) the aggregate Rentable Area of the Premises shall be 128,612 square feet, (c) the aggregate Rentable Area of the Building shall be 151,194 square feet, and (d) Tenant’s Pro Rata Share with respect to the entire Premises shall be eighty-five and six hundredths percent (85.06%).”
10.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 and agrees to reimburse, indemnify, save, defend (at Landlord’s option and with counsel reasonably acceptable to Landlord, at Tenant’s sole cost and expense) and hold harmless the Landlord Indemnitees for, from and against any and all cost or liability for compensation claimed by any such broker or agent employed or engaged by it or claiming to have been employed or engaged by it.
11.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.
12.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.
13.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.
14.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.
15.Authority.  Tenant guarantees, warrants and represents that the individual or individuals signing this Amendment 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.
