1.1.1 The Premises . Landlord hereby leases to Tenant and Tenant hereby leases from Landlord the Premises, which is a part of the Property. The outline of the Premises is set forth in Exhibit  A attached. The parties hereto agree that the lease of the Premises is upon and subject to the terms, covenants and conditions (the “ TCCs ”) set forth in this Lease, and Tenant and Landlord each covenants as a material part of the consideration for this Lease to keep and perform each and all of such TCCs by it to be kept and performed and that this Lease is made upon the condition of such performance. The parties hereto hereby acknowledge that the purpose of Exhibit  A , Exhibit  A-2 , and Exhibit  A-3 is to show the approximate location of the Premises, the Office Lobby, the Office Elevators, the Concession Area, the Project loading areas, Tenant’s Generator (as that term is defined in Section  6.5.1 below) and access to the Parking Garage, only, and such Exhibits are not meant to constitute an agreement, representation or warranty as to the construction of the Premises, the Building, or the Project, the precise area thereof or the specific location of the Common Areas, as that term is defined in Section  1.1.4 , below, or the elements thereof or of the accessways to the Premises, Building or the Project. Except as specifically set forth in this Lease and in the Tenant Work Letter attached hereto as Exhibit  B , including, without limitation, Landlord’s obligation to construct the Base, Shell and Core (as that term is defined in Section  1.1 of the Tenant Work Letter), and to satisfy the Final Completion Condition (as that term is defined in Section  1.5 of the Tenant Work Letter), Tenant shall accept each floor of the Premises in their “as is” condition as of the Lease Commencement Date, and Landlord shall not be obligated to provide or pay for any improvement work or services related to the initial improvement of the Premises. Tenant also acknowledges that neither Landlord nor any agent of Landlord has made any representation or warranty regarding the condition of the Premises, the Building or the Project or with respect to the suitability of any of the foregoing for the conduct of Tenant’s business, except as specifically set forth in this Lease and the Tenant Work Letter.

1.1.2 Office Lobby; Concession Area . As set forth in Section  2.1 of the Summary, the Building includes the lobby serving the Office Component located on the ground floor of the Building, as depicted on Exhibit  A-2 attached hereto (the “ Office Lobby ”). A portion of the Office Lobby, identified on Exhibit  A -2 as the “ Concession Area ” shall be leased or licensed by Landlord for use as a coffee bar or coffee shop, café, or other retail, restaurant, or concession space providing services or selling goods to the general public and the tenant(s) of the Building, such licensee, tenant or occupant of the Concession Area, is the “ Concessionaire ”. The Concession Area shall be improved, and shall be operated, including the use thereof, by the Concessionaire, consistent with the Class A Standard, and the improvement of the Concession Area shall be comparable to retail space of a similar use that is of comparable lobby location within the Comparable Buildings. The Concessionaire shall provide services or sell goods to the general public and the tenants of the Building, and otherwise, subject to the terms of this Section  1.1.2 , Landlord may lease or license the Concession Area to any Concessionaire selected by Landlord, in Landlord’s sole discretion; provided, however, prior to making a specific use of the Concession Area or changing any specific use of the Concession Area, including in connection with Landlord’s initial lease or license of the Concession Area, if such use will not be as a coffee bar, coffee shop, or similar use, Landlord shall first meet and confer with a representative of Tenant, to the extent a representative is made reasonably available to Landlord, regarding the proposed use of the Concession Area; provided, further however, any suggestions or requests made by Tenant’s representative shall not be binding on Landlord.

1.1.2.1 Turnstiles, Lobby Desk and Supplemental Security Equipment . As part of the construction of the Base, Shell and Core, as Tenant Change Items (as defined in the Tenant Work Letter), and pursuant to the terms of the Tenant Work Letter, Landlord shall construct turnstiles (the “ Turnstiles ”) and a lobby desk (the “ Lobby Desk ”) in the Office Lobby in the approximate locations shown on Exhibit  A-2 attached hereto, or other locations selected by Tenant, and reasonably approved by Landlord. Subject to Landlord’s approval (which shall not be unreasonably withheld or conditioned) and the terms of this Section  1.1.2.1 , in connection with the construction of the Base, Shell and Core, as Tenant Change Items, or at any time after the Lease Commencement Date and during the Lease Term, and pursuant to the TCCs of the Tenant Work Letter, Tenant shall have the right to cause Landlord to alter, modify or improve the interior of the Office Lobby with additional security infrastructure such as additional security cameras (collectively, the “ Supplemental Security ” and any related equipment or other

related physical property requested hereunder, the “ Supplemental Security Equipment ”). The Turnstiles, Lobby Desk and Supplemental Security Equipment, are, collectively, “ Tenant’s Lobby Installations ”. Tenant’s Lobby Installations shall not prohibit access to the Concession Area by the general public, nor prohibit access to the Office Component by other tenants or occupants of the Office Component, if any (the parties acknowledging that Tenant may satisfy such access requirements by providing, at Tenant’s sole cost, any other tenants or occupants of the Office Component with key cards that operate the Turnstiles). In connection with the foregoing, upon thirty (30) days prior written notice to Tenant, Landlord shall have the right to modify or relocate any of Tenant’s Lobby Installations, or, if relocation options are not commercially feasible, remove the applicable Tenant’s Lobby Installation, all at Tenant’s sole cost and expense, in order to provide for access as contemplated by the preceding sentence; provided, however Landlord shall, within such thirty (30) day period, first meet and confer with Tenant, to the extent a representative of Tenant is made reasonably available, to discuss Landlord’s access concerns. Landlord may only withhold or condition its consent to the design of Tenant’s Lobby Installations based upon the following, provided that such determination shall not be used by Landlord as a means of completely prohibiting Tenant from exercising its rights under this Section  1.1.2.1 : (i) Landlord’s reasonable determination that the proposed installation is not consistent, on an aesthetic basis, with the then existing improvements of the Building or the Office Lobby, (ii) the proposed installation materially and adversely affects the Building Systems or Building Structure, (iii) the failure of the installation to comply with Applicable Laws and/or (iv) the installation prohibiting the access that is required under this Section  1.1.2.1 . Tenant hereby acknowledges and agrees that Tenant shall be responsible for (a) all costs incurred in connection with the purchase and installation of Tenant’s Lobby Installations, (b) all actual, out-of-pocket costs incurred by Landlord (including, without limitation, repair and maintenance costs) as a result of, or in connection with, the operation and maintenance of Tenant’s Lobby Installations, and (c) upon the expiration or earlier termination of this Lease, if required by Landlord, the removal of Tenant’s Lobby Installations and the restoration of the affected areas to a Building standard condition reasonably acceptable to Landlord. Amounts due from Tenant hereunder shall be payable within thirty (30) days following demand, which demand shall include reasonably detailed documentation substantiating such costs. Notwithstanding any provision to the contrary set forth in this Lease or the Tenant Work Letter, the installation of Tenant’s Lobby Installations shall not be a requirement for Landlord’s satisfaction of the Completion Condition.

1.1.3 Hotel and The Sanctuary . As set forth in Section  2.1 of the Summary, the Project includes a Hotel on floors 2-16 of the Building and includes The Sanctuary. Once per calendar year, upon Tenant’s request, Landlord shall arrange a meeting between Tenant and the third-party operator of the Hotel (the “ Hotel Operator ”), and upon Tenant’s request, shall attend such meeting, in order to facilitate, without any obligation related to such facilitation, Tenant and the Hotel Operator discussing (i) making Hotel rooms available to Tenant on a priority basis, and at a discounted rate, and (ii) providing for Tenant’s ability to reserve conference space in the Hotel and to reserve space in The Sanctuary on a priority basis, and at a discounted rate. Landlord shall also disclose to Tenant, upon Tenant’s request, any non-confidential information, actually known by Landlord, relating to the pricing and availability of Hotel rooms and conference space to other large, corporate users of the Hotel. The terms of this Lease do not include any express or implied covenant or representation by Landlord that the Hotel and/or The Sanctuary shall operate or remain open during the Lease Term or that the Hotel shall remain a hotel or The Sanctuary shall remain a conference center and/or event space during the Lease Term.

1.1.4 Common Areas . Tenant shall have the non-exclusive right to use in common with other tenants and occupants in the Project (which term “ other tenants ” shall, as used in this Lease, include without limitation the Hotel Operator), and subject to the Rules and Regulations (as that term is defined in Article  5 of this Lease), those portions of the Project which are provided, and that are made available from time to time by Landlord and its successors, for use in common by Landlord and its successors, Tenant and any other tenants and occupants of the Project (such areas, together with such other portions of the Project designated by Landlord, in its discretion, including certain areas designated for the exclusive use of certain tenants, or to be shared by Landlord and certain tenants, are collectively referred to herein as the “ Common Areas ”). The term “ Building Common Areas ,” as used in this Lease, shall mean the portions of the Common Areas located within the Building that exclusively serve the tenants of the Office Component and includes the Office Lobby and Office Elevators. The term “ Project Common Areas ,” as used in this Lease, shall mean the portions of the Common Areas located within the Project and outside of the Building. The Building Common Areas and Project Common Areas shall be constructed in accordance with the Base Building Plans (as that term is defined in Section  1.1 of the Tenant Work Letter), and, from and after the Completion Date, the manner in which such Common Areas are maintained and operated shall be consistent with the common areas under the Class A Standard and the use thereof shall be subject to the Rules and Regulations.

Subject to the terms of this Section  1.1.4 , Landlord reserves the right to close temporarily, make alterations or additions to, or change the location of elements of the Project and the Common Areas. Except as and to the limited extent specifically permitted under this Lease or required by Applicable Laws, Landlord may not (i) materially and adversely affect Tenant’s right to use or access the Premises for the Standard Permitted Use or otherwise preclude Tenant from using the Premises for the Standard Permitted Use, (ii) materially and adversely affect Tenant’s ability to access or use the Parking Garage in accordance with Tenant’s rights set forth in this Lease, or Tenant’s ability to access or use the Critical Common Areas (as that term is defined in Section  1.1.4.1 below) or the Parking Garage, or (iii) materially impair or eliminate the visibility of Tenant’s Signage (as defined in Section  23.4 below), in each instance, other than temporary impacts caused by repairs, maintenance or replacements necessary to keep the Project in a condition consistent with the Class A Standard; and moreover, in exercising any rights under this Lease, Landlord shall use commercially reasonable efforts to minimize any material adverse effect upon Tenant’s ability to use the Premises for the Standard Permitted Use and the Critical Common Areas in a commercially reasonable manner (collectively, “ Landlord’s Obligations to Minimize Tenant Interference ”).

1.1.4.1 Critical Common Areas . The term “ Critical Common Areas ” as used in this Lease shall mean the Office Lobby (excluding the Concession Area, but subject to the terms of Section  1.1.2 above), the Office Elevators, the Bicycle Facilities (as defined in Article 28 below), and any portions of the Common Areas necessary to allow reasonable access the Premises or to have reasonable access to the Parking Garage in accordance with Tenant’s rights set forth in this Lease. After the Final Completion Date, Landlord may change, alter or modify the Critical Common Areas, including the finishes, furniture, and layout or operation of the Critical Common Areas (collectively, “ CCA Changes ”); provided, however, prior to commencing any material CCA Change (excluding CCA Changes (i) required by Applicable Laws, (ii) otherwise required in accordance with the TCCs of this Lease, (iii) reasonably necessary to address an emergency circumstance or Casualty (as that term is defined in Section  11.1 below) or (iv) constituting on-going repair and maintenance of the Critical Common Areas), (a) Landlord shall provide thirty (30) days’ advance written notice to Tenant identifying, in reasonable detail, the proposed CCA Change and the reason for the same, (b) Landlord shall at Tenant’s election, meet with Tenant at a commercially reasonable, mutually agreed upon time during the thirty (30) day period before the commencement of the CCA Change to discuss the same, (c) consider in good faith any reasonable objections of Tenant to the CCA Change by Tenant, whether such objection is made in writing during such thirty (30) day period or at the aforementioned meeting, and (d) if Landlord proceeds with the CCA Change, Landlord shall notify Tenant regarding the schedule for any work in connection with the CCA Change and, in connection with the foregoing, shall give reasonable consideration to any scheduling changes reasonably and promptly requested by Tenant. Following receipt of a schedule change request under item (d) hereof, if applicable, Landlord and Tenant shall cooperate with each other, on a commercially reasonable basis, so that Landlord may perform the subject work on a timely basis, but without material interference with the conduct of Tenant’s business from the Premises or Tenant’s use of the Critical Common Areas.

1.1.4.2 Tenant Common Areas . For purposes of this Lease, “ Tenant Common Areas ” shall mean the Office Lobby (excluding the Concession Area, but subject to the terms of Section  1.1.2 above), and the Office Elevators. In addition to the terms of Section  1.1.4.1 , prior to commencing any CCA Change to the Tenant Common Areas (“ TCA Changes ”), Landlord shall obtain Tenant’s approval, not to be unreasonably withheld, conditioned, or delayed, which approval shall be granted or denied within the thirty (30) day period described in (a) of Section  1.1.4.1 above, and Tenant’s failure to respond within such time period shall constitute Tenant’s deemed approval, provided that it shall be reasonable for Tenant to withhold or condition its consent if Tenant determines that the proposed TCA Change would, for example only and not by way of limitation: (i) materially and adversely impact (a) the size, accessibility, quality, functionality or features of the affected Tenant Common Areas for Tenant’s use of the same for or in connection with the Standard Permitted Use, or (b) any of Tenant’s rights under this Lease (including, without limitation, the right to signage and security features); or (ii) be inconsistent with the Class A Standard.

1.1.4.3 Access . Except to the extent Tenant’s right of access is specifically excluded or limited as the result of (i) an emergency which reasonably requires such exclusion or limitation, (ii) Applicable Laws, or (iii) the Rules and Regulations, and subject to the express TCCs of this Lease, Tenant shall have the right of reasonable (taking into account the Permitted Use) ingress and egress to and from the Premises and the Critical Common Areas twenty-four (24) hours per day, seven (7) days per week on each day during the Lease Term; provided, however, that in the event that Tenant’s ingress and egress to and from the Premises and the Critical

Common Areas is materially limited or denied for any reason, Landlord shall make commercially reasonable efforts to restore access as soon as reasonably practicable and to limit the scope, duration and extent of such limited or denied access to the scope, duration and extent actually and reasonably required by the circumstances justifying the limited or denied access. To the extent that Landlord breaches this Section  1.1.4.3 , Tenant’s rights in connection with such breach shall be governed by the terms of Section  6.4 and Section  7.3 of this Lease below.

1.2 Rentable Square Feet of Premises . For purposes of this Lease, “rentable square feet” of the Premises shall be calculated pursuant to Standard Methods of Measurement and Calculating Rentable Area – 2010 (Method A) (ANSI/BOMA Z65.1-2010), and its accompanying guidelines (collectively, “ BOMA 2010 ”). Landlord and Tenant hereby stipulate and agree that the rentable area of the Premises, based on the Base Building Plans (as that term is defined in Section  1.1 of the Tenant Work Letter) is as set forth in Section  2.2 of the Summary. Within sixty (60) days after the Lease Commencement Date, Tenant may object to the amount of the rentable square footage of the Premises as set forth in this Lease; provided, however, Tenant may only object if the Building, as constructed, deviates from the Base Building Plans and, as a result of such deviation, the rentable square footage of the Premises is reduced, and then any objection by Tenant to the rentable square footage of the Premises shall be limited solely to the amount of the actual deviation of the rentable square footages of the Premises from the rentable square footages set forth in this Lease. Tenant’s failure to deliver written notice of such objection within said sixty (60) day period shall be deemed to constitute Tenant’s acceptance of rentable square footage set forth in this Lease. If Tenant objects to the amount of the rentable square footage, Landlord’s space planner/architect and Tenant’s space planner/architect shall promptly meet and attempt to agree upon the rentable square footage of the Premises as measured pursuant to BOMA 2010, it being understood that any adjustment must be limited to the amount, if any, by which the rentable square footages of the Premises, as constructed, deviates from the rentable square footages set forth in this Lease (the “ Deviation ”). If Landlord’s space planner/architect and Tenant’s space planner/architect cannot agree on the amount of the Deviation within thirty (30) days after Tenant’s objection thereto, Landlord and Tenant shall mutually select an independent third party space measurement professional to field measure the Deviation pursuant to BOMA 2010, subject to the limitations set forth herein. Such third party independent measurement professional’s determination shall be conclusive and binding on Landlord and Tenant. Landlord and Tenant shall equally split the fees and expenses of the independent third party space measurement professional. If the Lease Term commences prior to the calculation of the Deviation, Landlord’s determination of the Deviation shall be utilized until a final determination of the Deviation is made, whereupon an appropriate adjustment, if necessary, shall be made retroactively, and Landlord shall make appropriate payment (if applicable) to Tenant. In the event that pursuant to the procedure described in this Section  1.2 above, it is determined that the rentable square footage amounts shall be different from those set forth in this Lease, all amounts, percentages and figures appearing or referred to in this Lease based upon such incorrect amount (including, without limitation, the amount of the Rent, as those term is defined in Section  4.1 of this Lease, and the amount of the Tenant Improvement Allowance, as that term is defined in Section  2.1 of the Tenant Work Letter) shall be modified in accordance with such determination. If such determination is made, it will be confirmed in writing by Landlord to Tenant.

ARTICLE 2

LEASE TERM; OPTION TERMS

2.1 Initial Lease Term . The TCCs and provisions of this Lease shall be effective as of the date of this Lease. Tenant may not occupy the Premises for the conduct of its business prior to the Lease Commencement Date. The term of this Lease (the “ Lease Term ”) shall be as set forth in Section  3.1 of the Summary, shall commence on the date set forth in Section  3.2 of the Summary (the “ Lease Commencement Date ”), and shall terminate on the date set forth in Section  3.4 of the Summary (the “ Lease Expiration Date ”) unless this Lease is sooner terminated or extended as hereinafter provided. For purposes of this Lease, the term “ Lease Year ” shall mean each consecutive twelve (12) Lease Month period during the Lease Term; provided, however, that the last Lease Year shall end on the Lease Expiration Date. For purposes of this Lease, the term “ Lease Month ” shall mean each succeeding calendar month during the Lease Term; provided that the first Lease Month shall commence on the Lease Commencement Date and shall end on the last day of the first (1st) full calendar month of the Lease Term and that the last Lease Month shall expire on the Lease Expiration Date. Within a reasonable period of time after the occurrence of the Lease Commencement Date, the parties shall execute a notice confirming key dates and other information in the form attached hereto as Exhibit  C , attached hereto, as a confirmation only of the information set forth therein; however, the failure of the parties to execute such letter shall not defer the Lease Commencement Date or otherwise invalidate this Lease or constitute a breach or default hereunder.

2.2 Option Terms .

2.2.1 Option Right . Landlord hereby grants Tenant three (3) options (each, an “ Extension Option ”) to extend the Lease Term for then-existing Premises each by a period of five (5) years (each an “ Option Term ”), pursuant to the TCCs of this Lease. Each Extension Option shall be exercisable only by Notice (as that term is defined in Section  29.18 of this Lease) delivered by Tenant to Landlord as provided below, provided that, as of the date of delivery of such Notice Tenant has not received notice of a monetary default under this Lease, which then remains uncured. Upon the proper exercise of such Extension Option, the Lease Term, as it applies to then-existing Premises, shall be extended for a period of five (5) years. The rights contained in this Section  2.2 may only be exercised by the tenant originally named herein (the “ Original Tenant ”) and its Permitted Transferee Assignee (as that term is set forth in Section  14.8 of this Lease) or an assignee of the entire Premises approved by Landlord under Article  14 of this Lease.

2.2.2 Option Rent . The Rent payable by Tenant during the Option Term (the “ Option Rent ”) shall be equal to the Market Rent, as that term is defined in, and determined pursuant to, Exhibit  F attached hereto. The calculation of the Market Rent shall be derived from a review of, and comparison to, the “Net Equivalent Lease Rates” of the comparable transactions, as provided for in Exhibit  F .

2.2.3 Exercise of Option . The Extension Options contained in this Section  2.2 shall be exercised by Tenant, if at all, only in the manner set forth in this Section  2.2 . Tenant shall deliver notice (the “ Exercise Notice ”) to Landlord not more than twenty-one (21) months nor less than eighteen (18) months prior to the expiration of the then Lease Term (the “ Option Exercise Deadline ”), stating that Tenant is exercising the applicable Extension Option; provided, however, that an Extension Option shall not lapse by reason of Tenant’s failure to give an Exercise Notice by the Option Exercise Deadline unless and until Landlord has given Tenant notice (an “ Option Reminder Notice ”) that the Option Exercise Deadline is approaching or has passed, as the case may be, and the Option Exercise Deadline shall be extended as necessary to give Tenant five (5) business days after receipt of an Option Reminder Notice in which to exercise the Extension Option. By way of example and for the avoidance of doubt, if Tenant has not theretofore exercised an Extension Option and (i) Landlord gives Tenant an Option Reminder Notice forty-five (45) days prior to the Option Exercise Deadline, Tenant must exercise the Extension Option not later than the Option Exercise Deadline, but (ii) if Landlord gives an Option Reminder Notice fifteen (15) days after the Option Exercise Deadline, the Option Exercise Deadline shall be deemed extended to the date that is five (5) business days after Landlord’s delivery of the Option Reminder Notice. Landlord shall deliver notice (the “ Landlord Response Notice ”) to Tenant on or before the date which is thirty (30) days after Landlord’s receipt of the Exercise Notice, setting forth Landlord’s calculation of the Market Rent (the “ Landlord’s Option Rent Calculation ”). Within ten (10) business days of its receipt of the Landlord Response Notice, Tenant may, at its option, accept the Market Rent contained in the Landlord’s Option Rent Calculation. If Tenant does not affirmatively accept or Tenant rejects the Market Rent specified in the Landlord’s Option Rent Calculation, the parties shall follow the procedure set forth in Section  2.2.4 below, and the Market Rent shall be determined in accordance with the terms of Section  2.2.4 below.

2.2.4 Determination of Market Rent . In the event Tenant timely exercises its option to extend this Lease, but rejects the Option Rent set forth in the Landlord’s Option Rent Calculation pursuant to Section  2.2.2 , above, then Landlord and Tenant shall attempt to agree upon the Option Rent using their best good-faith efforts. If Landlord and Tenant fail to reach agreement upon the Option Rent applicable to the Option Term on or before the date that is ninety (90) days prior to the expiration of the applicable Lease Term (the “ Outside Agreement Date ”), then each party shall, within five (5) days following the Outside Agreement Date, simultaneously exchange their separate determinations of the Option Rent (the “ Exchanged Option Rents ”). The Exchanged Option Rents shall be stated as a Net Equivalent Lease Rate. If the higher of the Exchanged Option Rents is within five percent (5%) of the lower of the Exchanged Option Rents, then the Option Rent shall be the average of the Exchanged Option Rents. If Landlord and Tenant disagree as to whether or not higher of the Exchanged Option Rents is within five percent (5%) of the lower of the Exchanged Option Rents, then the determination shall be made by an MAI appraiser selected by the parties and satisfying the requirements for the Neutral Arbitrator set forth in Section  2.2.4.2 below (the “ Exchanged Option Rents Arbitrator ”). If the parties cannot agree on an Exchanged Option Rents Arbitrator within thirty (30) days, either party may petition the

presiding judge of the King County Superior Court to appoint an MAI appraiser satisfying the requirements for the Neutral Arbitrator set forth in Section  2.2.4.1 below as the Exchanged Option Rents Arbitrator. If the higher of the Exchanged Option Rents is not within five percent (5%) of the lower of the Exchanged Option Rents, then the Exchanged Option Rents shall be submitted to arbitration in accordance with this Section  2.2.4. below, but subject to the terms, when appropriate, of Section  2.2.2 .

2.2.4.1 Landlord and Tenant shall, within fifteen (15) days of the Outside Agreement Date (or ten (10) days after the determination of the Exchanged Option Rents Arbitrator, if later), each appoint one arbitrator who shall by profession be an MAI appraiser or broker who shall have been active over the ten (10) year period ending on the date of such appointment in the appraising of, or rendering brokerage services relating to, first class office properties in the vicinity of the Building. The arbitrators so selected by Landlord and Tenant shall be deemed “ Advocate Arbitrators .”

2.2.4.2 The two Advocate Arbitrators shall, within fifteen (15) days of the appointment of the last appointed Advocate Arbitrator, agree upon and appoint a third arbitrator (“ Neutral Arbitrator ”) who shall be an MAI appraiser and otherwise qualified under the same criteria for an appraiser set forth hereinabove for qualification of an Advocate Arbitrator that is an appraiser except that (i) neither the Landlord or Tenant or either parties’ Advocate Arbitrator may, directly, or indirectly, consult with the Neutral Arbitrator prior or subsequent to his or her appearance, and (ii) the Neutral Arbitrator cannot be someone who has represented Landlord and/or Tenant during the five (5) year period prior to such appointment. The Neutral Arbitrator shall be retained via an engagement letter jointly prepared by Landlord’s counsel and Tenant’s counsel. If the Advocate Arbitrators do not agree on a Neutral Arbitrator within such fifteen-day period, either may petition the presiding judge of the King County Superior Court to appoint the appraiser. The decision of the Neutral Arbitrator shall be binding on Landlord and Tenant. After the Neutral Arbitrator is selected, the Advocate Arbitrators shall not be involved in the arbitration process, other than to advise, or advocate on behalf of, Landlord and Tenant, respectively. The following terms shall apply to the Neutral Arbitrator’s determination of whether Landlord’s or Tenant’s Exchanged Option Rent is the closest to the actual Option Rent.

2.2.4.2.1 Landlord and Tenant shall each have the right to submit to the Neutral Arbitrator (with a copy to the other party), on or before the date that occurs fifteen (15) days following the appointment of the Neutral Arbitrator, an advocate statement (and any other information such party deems relevant) prepared by or on behalf of Landlord or Tenant, as the case may be, in support of Landlord’s or Tenant’s respective determination of Option Rent;

2.2.4.2.2 The date, time and location of the arbitration shall be mutually and reasonably agreed upon by Landlord and Tenant;

2.2.4.2.3 No discovery by the Neutral Arbitrator or between Landlord and Tenant, or independent investigation by the Neutral Arbitrator shall take place in connection with the arbitration, except that the Neutral Arbitrator shall be permitted to visit the Project and the buildings containing the comparable transactions;

2.2.4.2.4 Tenant and Landlord shall each have the right to present oral arguments to the Neutral Arbitrator at the arbitration;

2.2.4.2.5 Not later than ten (10) business days after the date of the arbitration, the Neutral Arbitrator shall render a decision indicating whether Landlord’s or Tenant’s Exchanged Option Rent is closer to the Option Rent, and whichever Exchanged Option Rent is selected by the Neutral Arbitrator as being closer to the Option Rent shall become the then applicable Option Rent;

2.2.5 Amendment to Lease . Following the stipulation to, or determination of, Market Rent for the Premises for the Option Term, Landlord and Tenant shall promptly enter into an appropriate amendment to this Lease, extending the Lease Term for the Option Term with the Rent amended to be the Option Rent as so agreed or determined and otherwise on all of the applicable terms and conditions of this Lease, but the determination of the Option Rent shall be fully effective whether or not the such amendment is executed. In the event that the Option Rent shall not have been determined pursuant to the terms hereof prior to the commencement of the Option Term, Tenant shall continue to pay the Rent at the rate in effect immediately prior to commencement of the Option Term and upon the final determination of the Option Rent, the payments made by Tenant shall be reconciled with the actual amounts due, and the appropriate party shall make any corresponding payment to the other party.

2.3 Early Termination Right . Provided that Tenant has not received notice of a monetary default under this Lease that then remains uncured as of the date of Tenant’s delivery of the Termination Notice, as that term is defined below, Tenant shall have the right to terminate this Lease effective as of the first day of the one hundred thirty-ninth (139 ^th ) Lease Month of the Lease Term (the “ Termination Date ”), and provided that (i) Landlord receives written notice (the “ Termination Notice ”) from Tenant no later than the first day of the one hundred twentieth (120 ^th ) Lease Month of the Lease Term stating Tenant’s election to terminate this Lease pursuant to the terms and conditions of this Section  2.3 , together with fifty percent (50%) of the Termination Fee (as that term is defined below), and (ii) on or before the Termination Date, Landlord receives the remaining fifty percent (50%) of the Termination Fee, all as consideration for and as a condition precedent to such early termination. Provided that Tenant terminates this Lease pursuant to the terms of this Section  2.3 , this Lease shall automatically terminate and be of no further force or effect and Landlord and Tenant shall be relieved of their respective obligations under this Lease as of the Termination Date, except those obligations set forth in this Lease which relate to the term of Tenant’s lease of the Premises and/or that specifically survive the expiration or earlier termination of this Lease, including, without limitation, the payment by Tenant of all amounts owed by Tenant under the Lease, up to and including the Termination Date. For purposes of this Lease, the “ Termination Fee ” shall mean an amount equal to the then-unamortized portions, calculated using a five percent (5%) interest factor, on an equal payment basis over the number of Lease Months during which Base Rent is payable during the initial Lease Term (determined on a per rentable square foot basis for the then-existing Premises), of (a) the Tenant Improvement Allowance, (b) the Base Rent Abatement, and (c) leasing commissions paid by Landlord to Tenant’s Broker and Landlord’s Broker in connection with this Lease. Upon Tenant’s delivery of a Termination Notice (if applicable), Tenant’s rights, and Landlord’s restrictions, under Sections 2.2,  5.4 and 23.5 shall thereafter be void and of no further force or effect.

2.4 Pre-Lease Commencement Date Contraction Right . Provided that Tenant has not received notice of a monetary or material non-monetary default under this Lease that remains uncured as of the date of Tenant’s delivery of the Pre-LCD Contraction Notice, as that term is defined below, Tenant shall have the right to terminate its lease of the entirety of floors 46, 47 and 48 in the Building (the “ Pre-LCD Contraction Space ”) effective immediately upon delivery of the Pre-LCD Contraction Notice, provided that Landlord receives written notice (the “ Pre-LCD Contraction Notice ”) from Tenant no later than September 1, 2017, stating Tenant’s election to terminate its lease of the Pre-LCD Contraction Space, pursuant to the terms and conditions of this Section  2.4 . As a condition precedent to such contraction, concurrently with delivery of the Pre-LCD Contraction Notice, Tenant shall deliver the Pre-LCD Contraction Fee (as that term is defined below) to Landlord. For purposes of this Lease, the “ Pre-LCD Contraction Fee ” shall mean the leasing commissions paid by Landlord to Tenant’s Broker in connection with this Lease applicable to the Pre-LCD Contraction Space. Provided that Tenant terminates its lease of the Pre-LCD Contraction Space pursuant to the terms of this Section  2.4 , Tenant’s lease of the Pre-LCD Contraction Space shall automatically terminate and be of no further force or effect on the date of Tenant’s delivery of the Pre-LCD Contraction Notice, but Tenant’s lease of the remainder of the Premises shall remain in full force and effect and Landlord and Tenant shall be relieved of their respective obligations under this Lease with respect to the Pre-LCD Contraction Space. If Tenant timely exercises Tenant’s contraction right as set forth herein, then the applicable TCCs of Exhibit  I attached hereto shall apply, which Exhibit I shall provide the mechanism for appropriate adjustments to Base Rent, Tenant’s Share, and the Tenant Improvement Allowance based on the exclusion of the stipulated number of rentable square feet on the floor or floors in the Office Component which are no longer part of the Premises. Tenant shall execute an amendment to this Lease documenting the multi-tenant nature of the Project upon the applicable TCCs of Exhibit  I attached hereto within ten (10) business days of delivery of such amendment to Tenant by Landlord, but the TCCs of Exhibit  I shall be fully effective whether or not the such amendment is executed. Upon Tenant’s exercise of its contraction right set forth in this Section  2.4 above, Tenant’s contraction right set forth in Section  2.5 below shall terminate and be of no further force or effect. Landlord shall not be required to disburse any portion of the Tenant Improvement Allowance applicable to the Pre-LCD Contraction Space or construct any Tenant Change Items (as that term is defined in the Tenant Work Letter) applicable solely to the Pre-LCD Contraction Space prior to the expiration or earlier waiver of Tenant’s contraction right set forth in this Section  2.4 .

2.5 Contraction Right . Provided that Tenant has not received notice of a monetary default under this Lease that remains uncured as of the date of Tenant’s delivery of the Contraction Notice, as that term is defined

below, and Tenant did not exercise its contraction right set forth in Section  2.4 above, Tenant shall have the right to terminate its lease of the entirety of the two (2) highest full floors in the Premises (the “ Contraction Space ”) effective as of 11:59 p.m. on the date designated by Tenant in the Contraction Notice ( the “ Contraction Date ”) which date is on or between the last day of the seventy-eighth (78 ^th ) Lease Month and the last day of the ninetieth (90 ^th ) Lease Month, provided that (i) Landlord receives written notice (the “ Contraction Notice ”) from Tenant no later than twelve (12) Lease Months prior to the Contraction Date, and in any event, not later than the last day of the seventy-eighth (78 ^th ) Lease Month, stating Tenant’s election to terminate its lease of the Contraction Space, pursuant to the terms and conditions of this Section  2.5 and setting forth the Contraction Date and (ii) on or before the Contraction Date, Landlord receives the Contraction Fee (as that term is defined below), all as consideration for and as a condition precedent to such contraction. Provided that Tenant terminates its lease of the Contraction Space pursuant to the terms of this Section  2.5 , Tenant’s lease of the Contraction Space shall automatically terminate and be of no further force or effect on the Contraction Date, but Tenant’s lease of the remainder of the Premises shall remain in full force and effect and Landlord and Tenant shall be relieved of their respective obligations under this Lease as of the Contraction Date with respect to the Contraction Space, except those obligations set forth in this Lease which relate to the term of Tenant’s lease of the Contraction Space and/or that specifically survive the expiration or earlier contraction of this Lease with respect to the Contraction Space, including, without limitation, the payment by Tenant of all amounts owed by Tenant under the Lease with respect to the Contraction Space, up to and including the Contraction Date. For purposes of this Lease, the “ Contraction Fee ” shall mean the then-unamortized portions, calculated using a five percent (5%) interest factor, on an equal payment basis over the number of Lease Months during which Base Rent is payable during the initial Lease Term (determined on a per rentable square foot basis for the Contraction Space), of (a) the Tenant Improvement Allowance, (b) the Base Rent Abatement, and (c) leasing commissions paid by Landlord to Tenant’s Broker in connection with this Lease. If Tenant timely exercises Tenant’s contraction right as set forth herein, then the applicable TCCs of Exhibit  I attached hereto shall apply, which Exhibit  I shall provide the mechanism for appropriate adjustments to Base Rent and Tenant’s Share based on the exclusion of the stipulated number of rentable square feet on the floor or floors in the Office Component which are no longer part of the Premises. Tenant shall execute an amendment to this Lease documenting the multi-tenant nature of the Project upon the applicable TCCs of Exhibit  I attached hereto within ten (10) business days of delivery of such amendment to Tenant by Landlord, but the TCCs of Exhibit  I shall be fully effective whether or not the such amendment is executed.

ARTICLE 3

BASE RENT

3.1 In General . From and after the Rent Commencement Date, Tenant shall pay, without prior notice or demand, by ACH in currency or by wire transfer, which, at the time of payment, is legal tender for private or public debts in the United States of America, base rent (“ Base Rent ”) as set forth in Section  4 of the Summary, payable in equal monthly installments as set forth in Section  4 of the Summary in advance on or before the first day of each and every calendar month during the Lease Term, without any setoff or deduction other than setoffs and deductions that Tenant is permitted to make pursuant to the express TCCs of this Lease. Landlord shall provide its account information (including a completed form W-9) and wiring instructions within five (5) days of receipt of a request from Tenant. In accordance with Section  4 of the Summary, any increases in Base Rent shall occur on the first day of the applicable Lease Month. The parties acknowledge, however, that Tenant shall pay Base Rent for each “calendar month” of the Lease Term (or a prorated portion of a “calendar month”, as applicable), even though the first “Lease Month” may pertain to a period longer than one (1) calendar month. If any payment of Rent is for a period which is shorter than one month, the Rent for any such fractional month shall accrue on a daily basis during such fractional month and shall total an amount equal to the product of (i) a fraction, the numerator of which is the number of days in such fractional month and the denominator of which is the actual number of days occurring in such calendar month, and (ii) the then-applicable monthly installment of Base Rent. All other payments or adjustments required to be made under the TCCs of this Lease that require proration on a time basis shall be prorated on the same basis.

3.2 Base Rent Abatement . Provided that no monetary or material non-monetary event of default is occurring, then during the first four and one-half (4  ¹ ⁄ ₂ ) full calendar months of the Lease Term (collectively, the “ Base Rent Abatement Period ”), Tenant shall not be obligated to pay any Base Rent otherwise attributable to the Premises during such Base Rent Abatement Period (collectively, the “ Base Rent Abatement ”). Tenant

acknowledges and agrees that the foregoing Base Rent Abatement has been granted to Tenant as additional consideration for entering into this Lease, and for agreeing to pay the Rent and perform the terms and conditions otherwise required under this Lease.

3.3 Late Charges . If any installment of Rent or any other sum due from Tenant shall not be received by Landlord or Landlord’s designee within five (5) days of the date when due, then Tenant shall pay to Landlord a late charge equal to five percent (5%) of the overdue amount plus any attorneys’ fees incurred by Landlord by reason of Tenant’s failure to pay Rent and/or other charges when due hereunder; provided, however, with regard to the first such failure in any twelve (12) month period, Landlord will waive such late charge to the extent Tenant cures such failure within five (5) business days following Tenant’s receipt of written notice from Landlord that the same was not received when due. The late charge shall be deemed Additional Rent and the right to require it shall be in addition to all of Landlord’s other rights and remedies hereunder or at law and shall not be construed as liquidated damages or as limiting Landlord’s remedies in any manner. In addition to the late charge described above, any Rent or other amounts owing hereunder which are not paid within ten (10) days after the date they are due shall bear interest from the date when due until paid at the “Interest Rate.” For purposes of this Lease, the “ Interest Rate ” shall be an annual rate equal to the lesser of (i) the annual “ Bank Prime Loan Rate ” cited in the Federal Reserve Statistical Release Publication H.15(519), published weekly (or such other comparable index as Landlord and Tenant shall reasonably agree upon if such rate ceases to be published), plus three (3) percentage points, and (ii) the highest rate permitted by Applicable Laws.

3.4 Right to Offset Tenant Improvement Allowance . Notwithstanding anything to the contrary contained herein, if Landlord fails to timely fulfill its obligation to fund any portion of the Tenant Improvement Allowance, Tenant shall be entitled to deliver notice (“ Payment Notice ”) thereof to Landlord and to any mortgagee or trust deed holder of the Building whose identity and address have been previously provided to Tenant. If Landlord still fails to fulfill any such obligation within twenty (20) business days after Landlord’s receipt of the Payment Notice from Tenant and if Landlord fails to deliver notice to Tenant within such twenty (20) business day period explaining Landlord’s reasons that Landlord believes that the amounts described in Tenant’s Payment Notice are not due and payable by Landlord (“ Refusal Notice ”), Tenant shall be entitled to offset the amount so funded, together with interest at the Interest Rate from the date Landlord was obligated to pay such amount until the date of offset, against Tenant’s next obligations to pay Rent; provided, however, Landlord shall be obligated to immediately disburse to Tenant any undisputed amounts. However, if Tenant is in default under Section  19.1 of this Lease at the time that such offset would otherwise be applicable, Tenant shall not be entitled to such offset until such default is cured. If Landlord delivers a Refusal Notice, and if Landlord and Tenant are not able to agree on the amounts to be so paid by Landlord, if any, within ten (10) days after Tenant’s receipt of a Refusal Notice, then the parties agree to submit the matter to arbitration as herein described, specifically: (i) either party shall give written notice to the other that such dispute needs to be resolved by arbitration and (ii) within thirty (30) days after the giving of the notice, both parties shall submit the dispute to arbitration administered by the JAMS or any successor thereto in Seattle, Washington under the Expedited Procedures provisions (Rules 16.1-16.2 in the current edition) of the JAMS Comprehensive Arbitration Rules and Procedures. The determination rendered by the arbitrator shall be binding upon the parties and may be entered in any court having jurisdiction thereof, and the prevailing party shall be awarded its reasonable attorneys’ fees and costs. Tenant shall not be entitled to offset such amount against Rent unless and until such dispute is finally resolved by mutual agreement of the parties or pursuant JAMS arbitration as set forth above.

If Tax Expenses for any period during the Lease Term or any extension thereof are increased after payment thereof for any reason, including, without limitation, error or reassessment by applicable governmental or municipal authorities, Tenant shall pay Landlord upon demand Tenant’s Share of any such increased Tax Expenses included by Landlord as Tax Expenses pursuant to the TCCs of this Lease. Notwithstanding anything to the contrary contained in this Section  4.2.4 (except as set forth in Section  4.2.4.2 , above), there shall be excluded from Tax Expenses (i) all corporate taxes, income

taxes, excess profits taxes, franchise taxes, gift taxes, capital stock taxes, inheritance and succession taxes, estate taxes, federal and state income taxes, and other taxes to the extent applicable to Landlord’s general or net income (as opposed to rents, receipts or income attributable to operations at the Project), (ii) any items included as Operating Expenses, (iii) any items paid by Tenant under Section  4.5 of this Lease, and (iv) any taxes attributable to the portion of the Parking Garage located on land owned by the Rainier Club (as that term is defined in Section  28.1 below).

4.2.4.4 Except as otherwise set forth in this Section  4.2.4.4 below, only Landlord may institute proceedings to reduce Tax Expenses and the filing of any such proceeding by Tenant without Landlord’s consent shall constitute an event of default by Tenant under this Lease after the expiration of any applicable notice and cure periods. Except as set forth herein below, Landlord shall not be obligated to file any application or institute any proceeding seeking a reduction in Tax Expenses. Tenant may request from Landlord whether or not Landlord intends to file an appeal of any assessment or portion of Tax Expenses which are appealable by Landlord (the “ Appealable Tax Expenses ”) for any tax fiscal year. Landlord shall deliver written notice to Tenant within ten (10) days after such request indicating whether Landlord intends to file an appeal of Appealable Tax Expenses for such tax fiscal year. If Landlord indicates that Landlord will not file an appeal of such Appealable Tax Expenses, then Tenant may upon written notice to Landlord (“ Appeals Notice ”) file an appeal on behalf of Landlord. Tenant shall be solely responsible for all costs incurred in appealing Tax Expenses, including reimbursing Landlord, within thirty (30) days after written demand, for any and all costs reasonably incurred by Landlord. Tenant’s failure to timely deliver an Appeals Notice shall waive Tenant’s rights to appeal the applicable Tax Expenses for such tax fiscal year. In addition, Tenant’s obligations to reimburse Landlord for the costs incurred by Landlord in connection with the appeal pursuant to this Section shall survive the expiration or earlier termination of this Lease. Upon request, Landlord agrees to keep Tenant apprised of all tax protest filings and proceedings undertaken by Landlord to obtain a reduction or refund of Tax Expenses.

4.2.5 “ Tenant’s Share ” shall mean the percentage set forth in Section  6 of the Summary.

4.3 Cost Pools . Landlord shall allocate Direct Expenses between different portions or occupants of the Project (the “ Cost Pools ”) based on the respective rentable square footage of area of each Cost Pool as compared to the total rentable square footage of the Project, or if such allocation would not be equitable (as reasonably determined by Landlord), then Landlord may allocate Direct Expenses based on the respective benefit derived from each Cost Pool of the applicable Direct Expense. Such Cost Pools shall include a Cost Pool for items of Direct Expenses specific to the Office Component, and a Cost Pool for items of Direct Expenses specific to the Hotel. Tenants of the Project shall share, on an equitable basis, based on the respective rentable square footage of the Project, or, if such allocation would not be equitable (as reasonably determined by Landlord), then based on the respective benefit derived, any Direct Expenses under this Lease to the extent attributable to the Project as a whole or benefitting all occupants of the Project, as reasonably determined by Landlord using sound real estate management and accounting practices, consistently applied. Any costs allocated to a Cost Pool which does not include a portion of the Premises shall be excluded from the definition of Direct Expenses for the purposes of this Lease.

4.4 Calculation and Payment of Additional Rent . Tenant shall pay to Landlord, in the manner set forth in Section  4.4.1 , below, and as Additional Rent, Tenant’s Share of Direct Expenses for each Expense Year.

4.4.1 Statement of Actual Direct Expenses and Payment by Tenant . Landlord shall use commercially reasonable efforts to give to Tenant within one hundred twenty (120) days following the end of each Expense Year, a statement (the “ Statement ”) which shall state in reasonable detail the Direct Expenses incurred or accrued for such preceding Expense Year, and which shall indicate the amount of Tenant’s Share of Direct Expenses. Upon receipt of the Statement for each Expense Year commencing or ending during the Lease Term, Tenant shall pay, within thirty (30) days after receipt of the Statement, the full amount of Tenant’s Share of Direct Expenses for such Expense Year, less the amounts, if any, paid during such Expense Year as Estimated Direct Expenses, as that term is defined in Section  4.4.2 , below, and if Tenant paid more as Estimated Direct Expenses than the actual Tenant’s Share of Direct Expenses (an “ Excess ”), Tenant shall receive a credit in the amount of such Excess against Rent next due under this Lease or, if there is no further Rent due hereunder due to the expiration of the Lease Term or earlier termination of this Lease, then Landlord shall reimburse Tenant for the amount of such Excess within thirty (30) days. The failure of Landlord to timely furnish the Statement for any Expense Year shall not prejudice Landlord or Tenant from enforcing its rights under this Article  4 . Even though the Lease Term has

expired and Tenant has vacated the Premises, when the final determination is made of Tenant’s Share of Direct Expenses for the Expense Year in which this Lease terminates, if Tenant’s Share of Direct Expenses is greater than the amount of Estimated Direct Expenses previously paid by Tenant to Landlord, Tenant shall, within thirty (30) days after receipt of the Statement, pay to Landlord such amount, and if Tenant paid more as Estimated Direct Expenses than the actual Tenant’s Share of Direct Expenses (again, an Excess), Landlord shall, within thirty (30) days, deliver a check payable to Tenant in the amount of such Excess. The provisions of this Section  4.4.1 shall survive the expiration or earlier termination of the Lease Term. Notwithstanding the immediately preceding sentence, Tenant shall not be responsible for Tenant’s Share of any Direct Expenses attributable to any Expense Year which are first billed to Tenant more than two (2) calendar years after the expiration of the applicable Expense Year (other than Tax Expenses or utility billings or assessments).

4.4.2 Statement of Estimated Direct Expenses . In addition, Landlord shall use commercially reasonable efforts to give to Tenant by January 31st of the applicable Expense Year, a yearly expense estimate statement (the “ Estimate Statement ”) which shall set forth in reasonable detail Landlord’s reasonable estimate (the “ Estimate ”) of what the total amount of Direct Expenses for the then-current Expense Year shall be and the estimated Tenant’s Share of Direct Expenses (the “ Estimated Direct Expenses ”). Landlord’s failure to deliver the Estimate Statement by January 31 ^st of the applicable Expense Year shall not constitute a default by Landlord under this Lease. The failure of Landlord to timely furnish the Estimate Statement for any Expense Year shall not preclude Landlord from enforcing its rights to collect any Estimated Direct Expenses under this Article  4 , nor shall Landlord be prohibited from revising any Estimate Statement or Estimated Direct Expenses theretofore delivered to the extent necessary; provided, however, that Landlord shall not revise any Estimate Statement or Estimated Direct Expenses more than one (1) time per Lease Year. Thereafter, Tenant shall pay, within thirty (30) days after receipt of the Estimate Statement, a fraction of the Estimated Direct Expenses for the then-current Expense Year (reduced by any amounts paid pursuant to the second to last sentence of this Section  4.4.2 ). Such fraction shall have as its numerator the number of months which have elapsed in such current Expense Year, including the month of such payment, and twelve (12) as its denominator. Until a new Estimate Statement is furnished (which Landlord shall have the right to deliver to Tenant at any time), Tenant shall pay monthly, with the monthly Base Rent installments, an amount equal to one-twelfth (1/12th) of the total Estimated Direct Expenses set forth in the previous Estimate Statement delivered by Landlord to Tenant. Any amounts paid based on such an Estimate shall be subject to adjustment as provided in Section  4.4.1 above when actual Direct Expenses are available for each Expense Year. Throughout the Lease Term Landlord shall maintain records with respect to Direct Expenses in accordance with sound real estate management and accounting practices, consistently applied.

4.5 Taxes and Other Charges for Which Tenant Is Directly Responsible .

4.5.1 Tenant shall be liable for and shall pay ten (10) days before delinquency, taxes levied or assessed against (i) Tenant’s equipment, furniture, fixtures and any other personal property located in or about the Premises, and (ii) any of Tenant’s equipment or other property that may be located on or about the Project (other than inside the Premises) (collectively, “ Tenant’s Off-Premises Equipment ”). If any such taxes on Tenant’s equipment, furniture, fixtures and any other personal property are levied against Landlord or Landlord’s property or if the assessed value of Landlord’s property is increased by the inclusion therein of a value placed upon such equipment, furniture, fixtures or any other personal property and if Landlord pays the taxes based upon such increased assessment, which Landlord shall have the right to do regardless of the validity thereof but only under proper protest if requested by Tenant, Tenant shall upon demand repay to Landlord the taxes so levied against Landlord or the proportion of such taxes resulting from such increase in the assessment, as the case may be.

4.5.2 If the Tenant Improvements and Alterations in the Premises, whether installed and/or paid for by Landlord or Tenant and whether or not affixed to the real property so as to become a part thereof, are separately assessed for real property tax purposes at a valuation higher than the valuation at which tenant improvements conforming to Landlord’s “building standard” in other space in the Building are assessed, then the Tax Expenses levied against Landlord or the property by reason of such excess assessed valuation shall be deemed to be taxes levied against personal property of Tenant and shall be governed by the provisions of Section  4.5.1 , above.

4.5.3 Notwithstanding any contrary provision herein, Tenant shall pay prior to delinquency any (i) rent tax or sales tax, service tax, transfer tax or value added tax, or any other applicable tax on the rent or services herein or otherwise respecting this Lease, (ii) taxes assessed upon or with respect to the possession, leasing,

operation, management, maintenance, alteration, repair, use or occupancy by Tenant of the Premises or any portion of the Project, including the Project parking facilities; or (iii) taxes assessed upon this transaction or any document to which Tenant is a party creating or transferring an interest or an estate in the Premises.

4.6 Landlord’s Records . Upon Tenant’s written request given not more than ninety (90) days after Tenant’s receipt of a Statement for a particular Expense Year, and provided that Tenant is not then in default under this Lease beyond the applicable notice and cure period provided in this Lease, specifically including, but not limited to, the timely payment of Additional Rent, Landlord shall furnish Tenant with such reasonable supporting documentation pertaining to the calculation of Operating Expenses set forth in the Statement as Tenant may reasonably request, and Landlord shall make a knowledgeable representative available to a designated employee of Tenant to discuss Landlord’s determination of Operating Expenses set forth on the applicable Statement. Landlord shall provide such documentation and make a representative so available to Tenant within sixty (60) days after Tenant’s written request therefor and any discussions between Landlord’s representative and Tenant’s designated employee shall be non-binding on either party. Within one (1) year after receipt of a Statement by Tenant (the “ Audit Period ”), if Tenant disputes the amount of Direct Expenses set forth in the Statement, whether or not Tenant has exercised its foregoing rights set forth in this Section  4.6 above, an independent certified public accountant (which accountant (i) is a member of a nationally or regionally recognized certified public accounting firm, which has previous experience in auditing financial operating records of landlords of Comparable Buildings, and (ii) is not working on a contingency fee basis), designated and paid for by Tenant (“ Tenant’s Auditor ”), may, after reasonable notice to Landlord and at reasonable times, audit Landlord’s records with respect to the Statement, which records shall be made generally available at Landlord’s offices, or otherwise in hard copy, in King County, Washington, provided that (a) Tenant is not then in monetary default under this Lease (beyond the applicable notice and cure periods provided under this Lease), and (b) Tenant has paid all amounts required to be paid under the applicable Estimate Statement and Statement. In connection with such audit, Tenant and Tenant’s Auditor must agree in advance to follow Landlord’s reasonable rules and procedures regarding an audit of the aforementioned Landlord records, and shall execute a commercially reasonable confidentiality agreement regarding such audit. Tenant’s Auditor must complete the audit within ninety (90) days of Landlord making Landlord’s records available to Tenant and Tenant’s Auditor. Tenant’s failure to audit the amount of Direct Expenses set forth in any Statement within the Audit Period shall be deemed to be Tenant’s approval of such Statement and Tenant, thereafter, waives the right or ability to audit the amounts set forth in such Statement. If after such audit, Tenant still disputes such Direct Expenses, an audit to determine the proper amount shall be made, at Tenant’s expense, by an independent certified public accountant (the “ Accountant ”) mutually and reasonably selected by Landlord and Tenant; provided that if such audit by the Accountant proves that Direct Expenses set forth in the particular Statement were overstated by more than four percent (4%), then the cost of the Accountant and the cost of such audit shall be paid for by Landlord. If the Accountant shall determine that Tenant has overpaid Direct Expenses due under this Lease, Landlord shall refund to Tenant such overpayment within thirty (30) days following the determination by the Accountant. If the Accountant shall determine that Tenant has underpaid Direct Expenses due under this Lease, Tenant shall pay to Landlord the amount of such underpayment within thirty (30) days following the determination of the Accountant. Tenant hereby acknowledges that Tenant’s sole right to audit Landlord’s records and to contest the amount of Direct Expenses payable by Tenant shall be as set forth in this Section  4.6 , and Tenant hereby waives any and all other rights pursuant to Applicable Laws to audit such records and/or to contest the amount of Direct Expenses payable by Tenant.

ARTICLE 5

USE OF PREMISES

5.1 Permitted Use . Tenant shall use the Premises solely for the Permitted Use set forth in Section  7 of the Summary and Tenant shall not use or permit the Premises or the Project to be used for any other purpose or purposes whatsoever without the prior written consent of Landlord, which may be withheld in Landlord’s sole and absolute discretion.

5.2 Prohibited Uses . The uses prohibited under this Lease shall include, without limitation, use of the Premises or a portion thereof for (i) retail or restaurant uses, except for approved kitchens, cafeterias and pantries (not serving the general public); or (ii) radio and/or television stations, or other similar media outlets. Tenant shall not allow occupancy density for the Premises which is greater than permitted by Applicable Laws. Tenant further

covenants and agrees that it shall not use, or suffer or permit any person or persons to use, the Premises or any part thereof in violation of Applicable Laws or for any use or purpose contrary to the provisions of the Rules and Regulations (the rules and regulations, attached hereto as Exhibit D , are, the “ Existing Rules and Regulations ,” and together with such additional rules and regulations as Landlord may promulgate in accordance with the terms of this Lease, and as the Existing Rules and Regulations and additional rules may be amended or supplemented in accordance with the terms of this Lease, the “ Rules and Regulations ”). Landlord shall have the right to amend, supplement, and add new commercially reasonable rules and regulations to the Rules and Regulations at any time during the Lease Term, and such amendments, supplements, and new rules and regulations shall be deemed Rules and Regulations hereunder; provided, however, that notwithstanding anything to the contrary in this Lease, the Rules and Regulations shall be enforceable against Tenant only to the extent that (a) they are reasonable and consistent with the Class A Standard; (b) they are consistent with Landlord’s Obligations to Minimize Tenant Interference and do not otherwise materially increase Tenant’s obligations or materially decrease Tenant’s rights under this Lease; (c) Tenant has been provided notice in writing of such Rules and Regulations; and (d) the Rules and Regulations are applied and enforced in a reasonable, equitable and non-arbitrary manner. Tenant shall not do or permit anything to be done in or about the Premises which will unreasonably interfere with the rights of other tenants or occupants of the Building, or injure them or use or allow the Premises or any of Tenant’s Off-Premises Equipment to be used for any unlawful purpose, nor shall Tenant cause, maintain or permit any nuisance in, on or about the Premises.

5.3 Fitness Center . Tenant may use a portion of the Premises for the operation of a fitness center (the “ Fitness Center ”) which may include, without limitation, the following primary uses: weight and aerobic training, personal training, group training, fitness classes (including, for example only, yoga, Pilates, dance, aerobics, cycling and similar classes or group exercise activities), hot dry saunas; steam rooms; lockers and locker rooms; shower and restroom facilities; free weights and associated equipment; weight machines; rowing machines, treadmills, stationary bicycles, elliptical machines, stair-climbing machines, and similar exercise equipment, and shall in no event include installation or operation of a swimming pool or whirlpool facilities. The Fitness Center shall be for the exclusive use of Tenant’s and its subtenants’ employees and guests (collectively, the “ Fitness Center Users ”) and Tenant shall not make the Fitness Center available to other tenants or occupants of the Project (or their employees) or to members of the general public. The Fitness Center shall be of a size that does not violate Applicable Laws. Tenant’s obligations under this Section  5.3 are cumulative and in addition to all other obligations of Tenant under this Lease.

5.3.1 Licensing; Permits and Operation . The Fitness Center shall be constructed, if at all, as part of the Tenant Improvements. If approved by Landlord, the Fitness Center shall be installed and constructed in accordance with the Tenant Work Letter and this Section  5.3 at Tenant’s sole cost and expense (or as a deduction from the Tenant Improvement Allowance). Landlord shall use commercially reasonable efforts, at no cost to Landlord, to cooperate with Tenant to obtain all consents, approvals, permits or registrations required for operation of the Fitness Center, to the extent Landlord’s cooperation is required as owner of the Project. The Fitness Center shall be maintained and operated by Tenant, at Tenant’s expense, in the same manner and to the same standard applicable to the Premises generally and in compliance with all Applicable Laws. Notwithstanding the terms and conditions of Section  6.1.5 below, Landlord shall, at Tenant’s direct expense (and not as part of Operating Expenses), provide janitorial service for, and cleaning of, the Fitness Center. In addition, Tenant shall pay for any other actual and reasonable out-of-pocket increased costs incurred by Landlord with respect to the management, operation, maintenance and repair of the Building resulting solely from Tenant’s operation of the Fitness Center, within thirty (30) days of receiving an invoice therefor.

5.3.2 Waivers . Tenant or the Third Party Operator (as that term is defined in Section  5.3.3 below) of the Fitness Center shall use commercially reasonable efforts to make all Fitness Center Users aware that Landlord is not responsible for, nor affiliated with, the operation of the Fitness Center and that Landlord and the other Landlord Parties shall have no responsibility with respect thereto.

5.3.3 Third Party Operator . Tenant may exercise the right to operate a Fitness Center through subletting the Fitness Center to or the retention of a third party to operate the Fitness Center (a “ Third Party Operator ”); provided that any sublease shall be subject to Article 14 below and, if the Third Party Operator only operates the Fitness Center, the Third Party Operator must comply with, all of the terms, covenants, conditions and obligations on Tenant’s part to be observed and performed under this Lease to the extent they are reasonably

applicable to the Fitness Center (other than Tenant’s obligation to pay Base Rent or Direct Expenses under this Lease). Any violation of any provision of this Lease by the Third Party Operator shall be deemed, after the expiration of applicable notice and cure periods, to be a default by Tenant under such provision. Without waiving any right of Tenant under this Lease, Third Party Operator shall have no recourse against Landlord whatsoever on account of any failure by Landlord to perform any of its obligations under this Lease or on account of any other matter. All notices required of Landlord under this Lease shall be forwarded only to Tenant in accordance with the terms of this Lease and in no event shall Landlord be required to send any notices to any Third Party Operator. In no event shall any use or occupancy of any portion of the Premises by the Third Party Operator release or relieve Tenant from any of its obligations under this Lease. The Third Party Operator shall be a Tenant Party (as that term is defined in Section  10.1 below), and Tenant shall be fully and primarily liable for all acts and omissions of such Third Party Operator as fully and completely as if such Third Party Operator was an employee of Tenant. In no event shall the occupancy of any portion of the Premises by any Third Party Operator be deemed to create a landlord/tenant relationship between Landlord and such Third Party Operator or be deemed to vest in Third Party Operator any right or interest in the Premises or this Lease, and, in all instances, Tenant shall be considered the sole tenant under the Lease notwithstanding the occupancy of any portion of the Premises by any Third Party Operator. Upon request from Landlord, Tenant shall provide to Landlord a copy of the insurance required to be maintained by Third Party Operator prior to the Third Party Operator being allowed access to the Premises by Tenant. Any equipment or other property of the Third Party Operator in the Project shall be subject to Section  8.5 and Article  15 of this Lease. However, nothing in this Section  5.3 shall diminish Landlord’s or Tenant’s rights elsewhere in this Lease or imply that Landlord has any duties to the Third Party Operator. No disputes between Tenant and the Third Party Operator shall in any way affect the obligations of Tenant hereunder.

5.4 Competitors . So long as the Original Tenant or its Permitted Transferee Assignee leases and continues to occupy at least 300,000 of the rentable square feet of the Office Component, Landlord, during the Lease Term (as the same may be extended), shall not (i) enter into a lease for space (excluding the Premises) in the Office Component with a Competitor or Competitor Affiliate (as those terms are defined hereinbelow) or (ii) consent to the sublease or assignment of space in the Office Component to a Competitor or Competitor Affiliate, to the extent Landlord has the right to withhold its consent pursuant to the applicable lease document. Notwithstanding anything to the contrary contained herein, the TCCs of this Section  5.4 are not applicable to (a) any space in the Project located outside of the Office Component, and (b) the lease of any other tenant located in the Office Component who has been permitted to assign its lease or sublease space to a Competitor or Competitor Affiliate as the result of a court order. For purposes hereof, “ Competitor ” shall mean any of the following entities: (1) Amazon, (2) Zillow, (3) Facebook, (4) Google, (5) EMC, (6) Citrix Systems, (7) Radware, and (8) Palo Alto Networks, and “ Competitor Affiliate ” shall mean any entity that controls, or is controlled by, a Competitor and that primarily conducts business for application (ADN) technology for the delivery of web applications and the security, performance, availability of servers, data storage devices, and other network and cloud services (the “ Competitive Business ”). Once each year during the month of January during the Lease Term (and any extension thereof), Original Tenant or its Permitted Transferee Assignee shall have the right to replace or add one (1) Competitor with an alternative or new entity that Original Tenant or its Permitted Transferee Assignee reasonably determines primarily conducts a Competitive Business; provided, however, in no event shall the Competitor List ever include the names of more than eight (8) entities.

5.5 Underlying Documents; Initial CC&Rs .

5.5.1 Permitted Encumbrances; Underlying Documents . Tenant shall comply with, and Tenant’s rights and obligations under this Lease and Tenant’s use of the Premises shall be subject and subordinate to, all easements, licenses, operating agreements, declarations, restrictive covenants, or instruments encumbering the Project, including, without limitation, any covenants, conditions and restrictions affecting the Project, and reciprocal easement agreements affecting the Project, development agreements, and any agreements with transit agencies affecting the Project as of the date of this Lease (the “ Permitted Encumbrances ”). Landlord and Tenant agree that this Lease shall only be subject and subordinate to any future covenants, conditions, and restrictions and amendments thereto (the “ CC&Rs ”), as specifically required by Landlord pursuant to Section  5.5.2.2 , but subject to the TCCs of Section  5.5.2 below, which CC&Rs together with the Permitted Encumbrances, are the “ Underlying Documents ”.

5.5.2 Initial CC&Rs . Prior to the Final Completion Date, (i) Landlord shall record the condominium or subdivision or similar plan or map that will subdivide the Office Component from the Hotel, and (ii) Landlord shall record covenants, conditions and restrictions (including any subsequent amendments thereto, the “ Initial CC&Rs ”) that provide (a) for cost pooling materially consistent with the TCCs of Section  4.3 above, and requires any Hotel Operator to operate the Hotel at a level of service and quality that is equal to, or better than, a Mobile Travel Guide rating of “4-star”, (b) that the Hotel and/or The Sanctuary shall not be required to operate or remain open for any period of time, (c) that the Hotel shall not be required to remain a hotel for any period of time, and (d) that The Sanctuary shall not be required to remain a conference and/or event space for any period of time. Tenant hereby acknowledges and agrees that the initial Hotel Operator, SLS Hotels, and any of the following replacement Hotel Operators are acceptable to Tenant and satisfy the foregoing “4-star” rating: (1) Marriott International (including JW Marriott, and its other various brands), (2) Starwood Hotels and Resorts, (3) Hilton, (4) Hyatt, (5) Fairmont, (6) Four Seasons, (7) Omni, and (8) any other similar major regional or national hotel entity.

5.5.2.1 If Lease is Not Subordinate . Prior to recording the Initial CC&Rs, Landlord shall (i) provide Tenant a copy of the draft Initial CC&Rs that Landlord would otherwise be prepared to record, (ii) at Tenant’s election, meet with Tenant at a commercially reasonable, mutually agreed upon time within the succeeding ten (10) business day period to discuss the Initial CC&Rs, (iii) consider in good faith any reasonable comments or objections of Tenant to the Initial CC&Rs, whether such objection is made in writing during such ten (10) business day period or at the aforementioned meeting; provided, however, if Landlord does not require this Lease to become subordinate to the Initial CC&Rs, then Tenant shall only have the right to object to the Initial CC&Rs, if Landlord fails to cause the items set forth in Sections  5.5.2(ii)(a) , above, to be set forth in the Initial CC&Rs.

5.5.2.2 If Lease is Subordinate . If Landlord requires that this Lease become subordinate to the Initial CC&Rs or any other Underlying Documents (collectively, “ New Underlying Documents ”), excluding the Permitted Encumbrances, Tenant shall have the right to review and reasonably approve the applicable New Underlying Document within ten (10) business days of Landlord’s written request for such approval, except that Tenant may only disapprove the same to the extent the applicable New Underlying Document, or the implementation or enforcement of the New Underlying Document pursuant to the express provisions thereof: (i) would, in Tenant’s reasonable business judgment, (a) materially conflict with any of Tenant’s rights expressly set forth in this Lease, including, without limitation, rights relating to Tenant’s use of, and access to, the Project, Building Common Areas, Parking Garage or Premises, (b) materially conflict with any of Landlord’s obligations expressly set forth in this Lease, or (c) materially increase the costs imposed on Tenant under this Lease, or (ii) as to the Initial CC&Rs, the same do not include (a) the right for Landlord, as the owner of the Office Component, to enforce provisions and covenants of the Initial CC&Rs that benefit the Office Component against the other owners subject to the Initial CC&Rs, (b) limitations under the Initial CC&Rs that prevent express provisions of the Initial CC&Rs from being enforced in a manner that would violate the TCCs of this Section  5.5.2.2(i)(a) – (c) above, and (c) the right for Tenant to cause Landlord to exercise the enforcement rights in this Section  5.5.2.2(ii)(a) above, or, in the alternative, the right for Tenant to exercise such enforcement rights directly under the Initial CC&Rs. Tenant may not object to the terms of any New Underlying Documents that are consistent with the TCCs of Section  5.5.2 above. If Tenant is required by Landlord to subordinate to any New Underlying Documents, Landlord and Tenant shall execute commercially reasonable, appropriate documentation evidencing such subordination, in a form substantially similar to the form of Recognition of Covenants, Conditions, and Restriction, attached hereto as Exhibit  M .

ARTICLE 6

SERVICES AND UTILITIES

6.1 Standard Tenant Services . Throughout the Lease Term, Landlord shall cause all Building Systems to be operated and maintained in accordance with the Class A Standard. Landlord shall provide the following services at all times and on all days (unless otherwise stated below) during the Lease Term.

6.1.1 HVAC . In accordance with the Base Building Plans, the Building shall be equipped with a heating and air conditioning (“ HVAC ”) system serving the Office Component (the “ BB HVAC System ”). Subject to limitations imposed by all governmental rules, regulations and guidelines applicable thereto, Landlord shall provide BB HVAC System service in a manner consistent with the Class A Standard during the HVAC System

Hours. Tenant shall have the right to specify the hours of availability of the BB HVAC System, including specifying different hours for different floors of the Premises (the “ HVAC System Hours ”); provided, however, (i) the HVAC System Hours shall consist of, at a minimum, the hours of 7:00 A.M. to 6:00 P.M. on Monday through Friday and on Saturdays from 8:00 A.M. to 1:00 P.M., except for the date of observation of New Year’s Day, President’s Day, Memorial Day, Independence Day, Labor Day, Thanksgiving Day, and Christmas Day (collectively, the “ Holidays ”), and (ii) the HVAC System Hours shall consist only of consecutive time periods, as determined on a daily basis. Tenant shall cooperate fully with Landlord at all times and abide by all regulations and requirements that Landlord may reasonably prescribe for the proper functioning and protection of the BB HVAC System. If the HVAC System Hours consist of more than seventy-five (75) hours per week, as determined on average on a per floor basis for the entire Premises, then Landlord shall supply such HVAC to Tenant at Landlord’s actual cost (which shall be treated as Additional Rent, but not as an Operating Expense), including the cost of increased depreciation on the BB HVAC System, but excluding the cost of electricity to the extent already paid for directly by Tenant.

6.1.1.1 Supplemental HVAC . As a part of the Tenant Improvements and subject to the terms of the Tenant Work Letter, supplemental HVAC units may be installed in the Premises for the purpose of providing supplemental air-conditioning to the Premises (the “ Tenant HVAC  System ”). All aspects of the Tenant HVAC System (including, but not limited to, any connection to the Building’s chilled water system) shall be subject to Landlord’s prior written approval, which approval shall not be unreasonably withheld, conditioned or delayed, unless a Design Problem (as defined in Section  8.1 below) exists. At Landlord’s election prior to the expiration or earlier termination of this Lease, Tenant shall leave the Tenant HVAC System in the Premises upon the expiration or earlier termination of this Lease, in which event the Tenant HVAC System shall be surrendered with the Premises upon the expiration or earlier termination of this Lease, and Tenant shall thereafter have no further rights with respect thereto. In the event that Landlord fails to elect to have the Tenant HVAC System left in the Premises upon the expiration or earlier termination of this Lease, then Tenant shall remove the Tenant HVAC System upon the expiration or earlier termination of this Lease, and repair all damage to the Building resulting from such removal, at Tenant’s sole cost and expense. Tenant shall be solely responsible, at Tenant’s sole cost and expense, for the monitoring, operation, repair, replacement, and removal (subject to the foregoing terms of this Section  6.1.1.1 ), of the Tenant HVAC System, and in no event shall the Tenant HVAC System interfere with Landlord’s operation of the Building, but the Tenant HVAC System may, at Tenant’s option, connect to the Building management system. Any reimbursements owing by Tenant to Landlord pursuant to this Section  6.1.1.1 shall be payable by Tenant within thirty (30) days of Tenant’s receipt of an invoice therefor.

6.1.2 Electricity . Landlord shall provide adequate electrical wiring and facilities consistent with the Base Building Description (as that term is defined in the Tenant Work Letter) and power for normal general office use as determined by Landlord. Tenant’s use of electricity shall never exceed the capacity of the feeders to the Project, as described in the Base Building Description or the risers or wiring installation. Notwithstanding any provision to the contrary contained in this Lease, Tenant shall pay directly to Landlord pursuant to submeters installed by Landlord, the cost of all electricity provided to and/or consumed in the Premises (including normal and excess consumption and including the cost of electricity to operate the HVAC air handlers), which electricity shall be separately metered (as described above). Tenant shall pay such cost within thirty (30) days after demand and as Additional Rent under this Lease (and not as part of Operating Expenses).

6.1.3 Lighting . As part of Operating Expenses, Landlord shall replace lamps, starters and ballasts for Building standard lighting fixtures within the Premises. In addition, Tenant shall bear the cost of replacement of lamps, starters and ballasts for non-Building standard lighting fixtures within the Premises.

6.1.4 Water . As contemplated by the Base Building Plans, Landlord shall provide city water from the regular Building outlets for drinking, lavatory and toilet purposes in the Premises, and Common Areas.

6.1.5 Janitorial . Landlord shall provide janitorial services to the Premises in accordance with the Class A Standard and Comparable Buildings, except Holidays, in and about the Premises and window washing services in a manner and frequency consistent with other Comparable Buildings, but not less frequently than twice per calendar year. Notwithstanding the foregoing, upon request from Tenant, and at Tenant’s sole cost and expense with respect to the Office Component (which may be included within Operating Expenses, or charged directly to Tenant as Additional Rent), Landlord shall use commercially reasonable efforts to provide window washing services more frequently than twice per calendar year.

6.1.6 Office Elevators . Landlord shall provide (i) non-exclusive, non-attended automatic passenger elevator service, with at least two (2) passenger elevators available at all times, including, without limitation, on weekends, and on Holidays and (ii) exclusive, non-attended freight elevator service, with at least one (1) freight elevator available at all times, with scheduling reasonably managed by Tenant, subject to Applicable Laws, emergency, and subject to use of the freight elevator as required by Landlord to perform its obligations under this Lease.

6.1.7 Loading Areas . Tenant shall have the exclusive right to use the loading areas in the Parking Garage designated on Exhibit A-3 attached hereto as loading area 1 and loading area 2. Tenant shall coordinate all deliveries to the Premises using the foregoing loading areas. As of the date hereof, Landlord anticipates that the Hotel shall be entitled to the exclusive use of loading area 5. Tenant is not entitled to utilize any of the loading areas that are exclusively reserved for the Hotel. Landlord shall not grant exclusive use of any loading areas, other than the two (2) loading areas designated for Tenant’s exclusive use as set forth herein and one (1) loading area designated for the Hotel’s exclusive use.

6.1.8 Access Control; Tenant’s Security System .

6.1.8.1 Access Control . Landlord shall, as part of Operating Expenses, provide on-site access control procedures and security services twenty-four (24) hours a day, seven (7) days a week, consistent with such service in Comparable Buildings. Although Landlord agrees to provide such access control procedures and security services, notwithstanding anything to the contrary contained in this Lease, the “Landlord Parties,” as that term is defined in Section  10.1 of this Lease, shall not be liable for, and the Landlord Parties are hereby released from any responsibility for any damage either to person or property sustained by Tenant incurred in connection with or arising from any acts or omissions of such access control personnel, or the Landlord Parties; provided, however, that Landlord shall remain liable for personal injury and/or property damage to the extent directly caused by the negligence or willful misconduct of Landlord’s access control personnel or the Landlord Parties (but in any event Landlord shall not be liable hereunder for the acts or omissions of any third parties at the Project).

6.1.8.2 Tenant’s Security System in the Premises . Subject to the terms and conditions of this Lease (including Article  8 hereof), Tenant may, at its own expense, install, maintain, repair and replace from time to time, its own security system (“ Tenant’s Security System ”) in the Premises, which may be a Lenel access system. If not installed as part of the Tenant Improvements and approved by Landlord in accordance with the Tenant Work Letter, Tenant shall coordinate the selection, installation and operation of Tenant’s Security System with Landlord, and Landlord likewise shall cooperate with Tenant, in order to ensure that Tenant’s Security System is compatible with Landlord’s Building security systems and equipment, and to the extent that Tenant’s Security System is not compatible with Landlord’s Building systems and equipment, Tenant shall not be entitled to install and/or operate the Tenant’s Security System. Tenant shall be solely responsible, at Tenant’s sole cost and expense, for the installation, monitoring, operation and removal of Tenant’s Security System. Tenant may coordinate Tenant’s Security System to provide that the Building Systems and Tenant’s Security System will operate on the same type of key card, so that Tenant’s employees are able to use a single card for both systems, but shall not otherwise integrate Tenant’s Security System with the Building Systems.

6.2 Overstandard Tenant Use . Tenant shall not, without Landlord’s prior written consent, which consent shall not be unreasonably withheld, conditioned or delayed, use office equipment or lighting (other than lighting installed as Tenant Improvements), which may that individually or collectively cause the air conditioning system serving the Premises to be unable, on a commercially reasonable basis, to maintain appropriate temperatures in the Premises in compliance with this Lease. If Tenant’s density or machines or equipment (i) affects the temperature otherwise maintained by the HVAC system or (ii) otherwise exceeds the capacity of any utility, Landlord may, after notice to Tenant and a reasonable opportunity for Tenant to cease such overstandard use, install supplemental air conditioning units or other supplemental equipment in the Premises, and the cost thereof, including the cost of design, installation, operation, use, and maintenance shall be paid by Tenant to Landlord within thirty (30) days after Landlord has delivered to Tenant an invoice therefor. Notwithstanding any provision to the contrary contained in this Lease, Tenant shall pay to Landlord within thirty (30) days after Landlord has delivered to Tenant an invoice therefor, Landlord’s standard charge for any services provided to Tenant which Landlord is not specifically obligated to provide to Tenant pursuant to the terms of this Lease.

6.3 Interruption of Use . Except as set forth to the contrary in Section  6.4 below, Tenant agrees that Landlord shall not be liable for damages, by abatement of Rent or otherwise, for failure to furnish or delay in furnishing any service (including telephone and telecommunication services), or for any diminution in the quality or quantity thereof, when such failure or delay or diminution is occasioned, in whole or in part, by breakage, repairs, replacements, or improvements, by any strike, lockout or other labor trouble, by inability to secure electricity, gas, water, or other fuel at the Building or Project after reasonable effort to do so, by any riot or other dangerous condition, emergency, accident or Casualty whatsoever, by act or default of Tenant or other parties, or by any other cause beyond Landlord’s reasonable control; and such failures or delays or diminution shall never be deemed to constitute an eviction or disturbance of Tenant’s use and possession of the Premises or relieve Tenant from paying Rent or performing any of its obligations under this Lease, except as otherwise provided in Section  6.4 or elsewhere in the Lease. Furthermore, Landlord shall not be liable under any circumstances for a loss of, or injury to, property or for injury to, or interference with, Tenant’s business, including, without limitation, loss of profits, however occurring, through or in connection with or incidental to a failure to furnish any of the services or utilities as set forth in this Article  6 .

6.3.1 Procedures for Interrupting Services . Prior to any scheduled interruption in services or utilities (other than as requested by Tenant), Landlord shall (i) give or cause to be given ten (10) business days’ advance written notice to Tenant identifying, in reasonable detail, the proposed interruption, the reason therefor and the schedule for its completion, (ii) if Tenant requests, meet with Tenant at a commercially reasonable, mutually agreed upon time during such ten (10) business day period to discuss the interruption, (iii) consider reasonably and in good faith any reasonable objections of Tenant to the proposed interruption, (iv) if the interruption proceeds longer than the scheduled completion initially provided to Tenant, provide periodic updates to Tenant regarding the status thereof and any changes to the schedule for its completion and (v) in connection with the foregoing, give reasonable, good faith consideration to any scheduling changes reasonably requested by Tenant. Landlord shall comply with Landlord’s Obligations to Minimize Tenant Inference in connection with any schedule interruption in services or utilities. In any emergency, or unscheduled interruption in services or utilities of which Landlord has actual knowledge, Landlord shall provide notice to Tenant (via email to an email address or addresses designated by Tenant in written notice(s) delivered to Landlord from time to time), as soon as reasonably practicable, and shall provide any information that Landlord may have about the interruption (including the anticipated timing for ceasing of the interruption).

6.4 Abatement Event . In the event that Tenant is prevented, without taking extraordinary measures or incurring material expense, from using the Premises (or any portion thereof) for the Permitted Use, and does not thereafter use, the affected portion of the Premises for Permitted Uses as a result of (i) any repair, maintenance, alteration, or remediation performed by Landlord, or which Landlord fails to perform, after the Lease Commencement Date and required by the Lease, (ii) any failure of Landlord to provide, or any material restriction of, services to the Premises, utilities to the Premises, or materially necessary access to the Premises, Critical Common Areas, or Parking Garage, in all events as required by this Lease, (iii) any Renovations, as that term is defined in Section  29.30 of this Lease, or (iv) during any period of remediation, removal, abatement, or encapsulation of any hazardous materials required to be performed by Landlord pursuant to this Lease (such set of circumstances as set forth in items (i), (ii) (iii), or (iv) above, to be known as an “ Abatement Event ”), then Tenant shall give Landlord notice of such Abatement Event, which notice may be provided by email to an email address or addresses designated by Landlord in written notice(s) delivered to Tenant from time to time, so long as notice is concurrently provided as required under Section  29.18 of this Lease, by recognized overnight courier service for next day delivery, and if such Abatement Event continues for three (3) consecutive business days (one (1) business days in the event of a failure to provide access as required under Section  1.1.4.3 of this Lease) after any such notice (the “ Eligibility Period ”), then the Base Rent and Tenant’s Share of Direct Expenses shall be abated or reduced, as the case may be, after expiration of the Eligibility Period for such time that Tenant continues to be so prevented from using the Premises (or any portion thereof) for the Permitted Use without taking extraordinary measures or incurring material expense, and does not use, the Premises or any portion thereof, for the Permitted Use, in the proportion that the rentable area of the portion of the Premises that Tenant is prevented from using for the Permitted Use without taking extraordinary measures or incurring material expense, and does not use for the Permitted Use, bears to the total rentable area of the Premises; provided, however, in the event that Tenant is prevented from using for the Permitted Use without taking extraordinary measures or incurring material expense, and does not use, a portion of the Premises for the Permitted Use for a period of time in excess of the Eligibility Period and the remaining portion of the Premises is not sufficient to allow Tenant to effectively conduct its business therein, and if

Tenant does not conduct its business from such remaining portion, then for such time after expiration of the Eligibility Period during which Tenant is so prevented from effectively conducting its business therein, the Base Rent and Tenant’s Share of Direct Expenses for the entire Premises shall be abated for such time as Tenant continues to be so prevented from using for the Permitted Use, and does not use for the Permitted Use, the Premises. If, however, Tenant reoccupies any portion of the Premises during such period and recommences use of such portion of the Premises for the Permitted Use, the Rent allocable to such reoccupied portion, based on the proportion that the rentable area of such reoccupied portion of the Premises bears to the total rentable area of the Premises, shall be payable by Tenant from the date Tenant reoccupies such portion of the Premises. For the avoidance of doubt, the unavailability of all Office Elevators shall, subject to the terms of this Section  6.4 , be deemed to be an Abatement Event giving rise to Tenant’s rights under this Section  6.4 . Landlord shall use commercially reasonable efforts to minimize the duration of an Abatement Event within Landlord’s reasonable control, provided that such right to abate Base Rent and Tenant’s Share of Direct Expenses and Tenant’s rights under Section  7.3 , if and to the extent applicable, shall be Tenant’s sole and exclusive remedies at law or in equity for an Abatement Event. Except as provided in this Section  6.4 , nothing contained herein shall be interpreted to mean that Tenant is excused from paying Rent due hereunder. For purposes of this Section  6.4 , a “ material restriction ” shall mean a restriction of services, utilities or access such that Tenant cannot reasonably use the Premises as permitted by this Lease.

6.5 Generator .

6.5.1 In General . Subject to the terms hereof (including, without limitation, the Tenant Work Letter and Article 8 of this Lease, as applicable) and Applicable Laws, Tenant shall have the right, at Tenant’s sole cost and expense, to install one (1) back-up generator (the “ Generator ”) in the location set forth on Exhibit  A-3 , attached hereto (the “ Generator Area ”) to service the Premises in the event of a power outage. For purposes of this Lease, the “Generator” shall be deemed to include, without limitation, all associated equipment, connections and/or facilities and shall be considered a part of Tenant’s Off-Premises Equipment. All plans and specifications relating to the Generator shall be subject to the approval of Landlord, which shall not be unreasonably withheld, conditioned or delayed; provided however, the Generator shall not exceed the specifications described on Exhibit  L attached hereto. Subject to the terms of this Section  6.5 , Landlord shall permit Tenant, at its sole cost and expense, to install and maintain the Generator, all in compliance with Applicable Laws. The cost of design (including engineering costs) and installation of the Generator and the costs of the Generator itself shall be Tenant’s sole responsibility.

6.5.2 Operation and Maintenance of Generator . In no event shall Tenant permit the Generator to interfere with normal and customary use or operation of the Building and Project by Landlord or other tenants and/or occupants (including, without limitation, by means of noise or odor). Tenant shall be responsible, at Tenant’s sole cost and expense, for all maintenance and repairs and compliance with Law obligations (including, without limitation, any Department of Ecology requirements imposed with respect to the fuel tank) with respect to the Generator, and Tenant acknowledges and that Landlord shall have no responsibility in connection with the Generator and that Landlord shall not be liable for any damage that may occur with respect to the Generator, provided that Landlord shall remain liable for property damage to the Generator to the extent caused by Landlord’s negligence or willful misconduct. Without limitation of the foregoing provisions of this Section  6.5.2 , all matters (including all plans and specifications) relating to the installation, connection, use, maintenance, repair, compliance with Laws, and removal of the Generator (including, without limitation, the manner and means of Tenant’s connection of the Generator to the electrical systems of the Building) shall be subject to the prior approval of Landlord, which approval shall not be unreasonably withheld and may be conditioned on Tenant complying with such reasonable requirements imposed by Landlord, based on the advice of Landlord’s engineers, so that the Building Systems or other components of the Building and the occupants of the Building are not adversely affected by the installation and operation of the Generator, and/or based upon other reasonable factors as determined by Landlord. In the event that Tenant shall fail to comply with the requirements set forth herein within a reasonable period of time following notice from Landlord (provided that no notice shall be required in the case of an emergency), without limitation of Landlord’s other remedies, Landlord shall have the right, at Tenant’s sole cost and expense, to cure such breach, in which event Tenant shall be obligated to pay to Landlord, within thirty (30) days following demand by Landlord, the amount expended by Landlord. Tenant shall maintain, at Tenant’s cost, industry standard “boiler and machinery” insurance coverage with respect to the Generator.

6.5.3 Generator Use . The Generator shall be used by Tenant only during (i) testing and regular maintenance, and (ii) the period of any electrical power outage or interruption in the Building. Tenant shall be entitled to operate the Generator for testing and regular maintenance only at reasonable times when permitted by Applicable Laws.

6.5.4 Landlord Costs . Except to the extent resulting from the negligence or willful misconduct of any Landlord Party or Landlord’s violation of this Lease, Tenant shall be responsible for any and all costs, if any, incurred by Landlord as a result of or in connection with Tenant’s installation, operation, use and/or removal of the Generator. In the event that Landlord shall incur any such costs as a result of or in connection with the rights granted to Tenant herein, Tenant shall reimburse Landlord for the same within thirty (30) days following billing.

6.5.5 Removal of Generator . The Generator shall remain Tenant’s property and Tenant may, at Tenant’s sole cost and expense, remove the Generator at any time during the Lease Term, provided that Tenant repairs all damage to the Building and Project resulting from the use and removal of the Generator and restores all affected areas to their condition existing prior to the installation thereof (collectively, the “ Generator Restoration Obligations ”). If Tenant shall not elect to remove the Generator during the Lease Term in accordance with the preceding terms, notwithstanding anything contained herein to the contrary, at Landlord’s option (which shall be made, if at all, by notice to Tenant at the time of Landlord’s approval of the plans and specifications for the initial installation of the Generator), Tenant shall be obligated, at Tenant’s sole cost and expense, to remove the Generator and to perform all Generator Restorations Obligations prior to the expiration or earlier termination of this Lease (or upon any earlier termination of Tenant’s rights with respect to the Generator as provided hereunder). The foregoing obligations of Tenant shall survive the expiration or earlier termination of this Lease.

6.6 Property Management . Daniels Real Estate LLC (“ DRE ”) will act as property manager (“ Property Manager ”) providing property management services for the Office Component, as of the Lease Commencement Date. At all times during the Term, the Property Manager shall be provided by DRE or a first-class institutional property manager with experience providing services to comparable Class A office projects. Landlord shall not change the Property Manager without first providing to Tenant advance notice and a reasonable opportunity for Tenant to meet and confer with Landlord regarding Landlord’s proposed Property Manager and obtaining Tenant’s prior consent; provided, however, that Tenant’s consent shall not be required if the replacement Property Manager is an affiliate of DRE or Stockbridge Capital Partners or is a first-class institutional property manager with experience providing services to comparable Class A office projects (but Landlord shall provide advance notice and a reasonable opportunity for Tenant to meet and confer with Landlord).

ARTICLE 7

REPAIRS AND MAINTENANCE

7.1 Repair and Maintenance by Tenant . At all times during the Lease Term, subject to Article  8 below, Tenant shall, at Tenant’s own expense, keep all portions of the Premises (excluding the Building Systems and other items to be maintained by Landlord pursuant to Section  7.2 ) in good order, repair and condition, reasonable wear and tear and damage from Casualty that is not Tenant’s obligation to repair hereunder excepted, and in accordance with all Applicable Laws and the equipment manufacturer’s suggested service programs, including all improvements, fixtures, furnishings, and systems and equipment therein (including, without limitation, plumbing fixtures other than plumbing fixtures in Common Area restrooms (as opposed to restrooms located on any full floors of the Premises, which shall be Tenant’s obligation to repair and maintain) and equipment such as dishwashers, garbage disposals, and instant hot dispensers), and any of Tenant’s Off-Premises Equipment and all areas, improvements and systems exclusively serving the Premises, including the branch lines of the plumbing, electrical and BB HVAC System, including the Tenant HVAC System, all duct work, and the floor coverings in the Premises. In addition, Tenant shall, at Tenant’s own expense, but under the supervision and subject to the prior approval of Landlord, and within any reasonable period of time specified by Landlord, promptly and adequately repair all damage to the Premises and replace or repair all damaged, broken, or worn fixtures and appurtenances, except for damage caused by reasonable wear and tear associated with reasonable, normal and customary use of the item in question that does not impair the function of the item in question for its intended use (“ reasonable wear and tear ”); provided however, that, at Landlord’s option, or if Tenant fails to make such repairs after the expiration of applicable notice and cure periods, Landlord may, but need not, make such repairs and replacements, and Tenant shall pay Landlord the cost thereof, within thirty (30) days of being billed for same. If the Premises include, now or hereafter, one or more floors of the Building in their entirety, all corridors and restroom facilities located on such full floor(s) shall be considered to be a part of the Premises.

7.2 Repair and Maintenance by Landlord . Notwithstanding the foregoing, Landlord shall maintain, repair, replace, and correct all latent defects in, as needed, the Base Building (including the core portions of the Building Systems) and Common Areas, as necessary to maintain the Base Building and Common Areas in condition consistent, in all material respects, with the Class A Standard, including maintenance, repair and replacement of the exterior of the Project (including painting) and landscaping, except to the extent that such repairs are required due to the negligence or willful misconduct of Tenant; provided, further, however, that, subject to the terms of Section  10.3.2.2 of this Lease, if such repairs are due to the negligence or willful misconduct of Tenant, Landlord shall nevertheless make such repairs at Tenant’s expense, or, if covered by Landlord’s insurance, Tenant shall only be obligated to pay any deductible in connection therewith. Landlord shall also operate, maintain, repair and replace the Building Systems as necessary in order to keep airborne concentrations of spores and other products of toxic molds and other biota below levels that are generally recognized as injurious to human health; provided, however, Landlord shall be deemed to be satisfying the foregoing requirement if Landlord constructs the Building Systems in accordance with the Base Building Plans, and maintains and operates the same in accordance with their operating specifications. Landlord may, but shall not be required to, enter the Premises at all reasonable times, subject to Article  27 below, to make such repairs, alterations, improvements or additions to all or any portion of the Premises, the Base Building or the Project as Landlord shall desire or deem necessary, or as Landlord may be required to do under Applicable Laws, or by governmental or quasi-governmental authority, or by court order or decree. All costs in performing the work described in this Section  7.2 shall be included in Direct Expenses, except to the extent excluded by Section  4.2.3 .

7.3 Tenant’s Right to Make Repairs . Notwithstanding any of the terms set forth in this Lease to the contrary, if Tenant provides Notice (or oral notice in the event of an Emergency Condition, as that term is defined, below) to Landlord of an event or circumstance which requires the action of Landlord with respect to repair and/or maintenance required to be performed by Landlord under this Lease that relates to (i) any floor leased by Tenant, (ii) any Building Systems, (iii) the Critical Common Areas, or (iv) any Emergency Condition, which event or circumstance materially and adversely affects the conduct of Tenant’s business from the Premises or Tenant’s access to the Premises and/or Critical Common Areas, without Tenant being obligated to take extraordinary measures or incur material expense, and Landlord fails to commence corrective action within a reasonable period of time, given the circumstances, after the receipt of such Notice, but in any event not later than ten (10) business days after receipt of such Notice and to diligently prosecute the corrective action to completion, then Tenant may proceed to take the required action upon delivery of an additional five (5) days’ Notice to Landlord specifying that Tenant is taking such required action (provided, however, that the initial ten (10) business day Notice and the subsequent five (5) day Notice shall be replaced with a single twenty-four (24) hour notice in the event of an Emergency Condition) and if such action was required under the terms of this Lease to be taken by Landlord and was not commenced by Landlord within such ten (10) business day period (or within twenty-four (24) hours in the event of an Emergency Condition) and thereafter diligently pursued to completion, then Tenant shall be entitled to prompt reimbursement by Landlord of Tenant’s reasonable costs and expenses in taking such action. Notwithstanding anything contained herein to the contrary, in no event shall Tenant be permitted to take any action under this Section  7.3 that relates to the Building Structure, as that term is defined in Section  8.2 of this Lease.

7.3.1 Emergency Condition Defined . For purposes of this Section  7.3 , the term “ Emergency Condition ” shall mean any event or circumstance which requires repair or maintenance by Landlord under this Lease and which (i) creates an immediate material risk (a) of physical harm to any Tenant Party, or (b) to the protection, safety, operation and preservation of Tenant’s mission-critical or business-critical personal property in the Premises (including, for example, server rooms), or (ii) prevents Tenant from accessing the Premises or Critical Common Areas on a commercially reasonable basis.

7.3.2 Other Terms . In the event Tenant takes such action pursuant to this Section  7.3 , Tenant shall use only those contractors used by Landlord in the Building for work unless such contractors are unwilling or unable to perform, or timely perform, such work, in which event Tenant may utilize the services of any other qualified contractor which normally and regularly performs similar work in Comparable Buildings. Promptly following completion of any work taken by Tenant pursuant to the terms of this Section  7.3 , Tenant shall deliver a detailed invoice of the work completed, the materials used and the costs relating thereto. If Landlord does not either

(i) pay such amounts, or (ii) deliver a detailed written objection to Tenant within ten (10) business days after receipt of an invoice from Tenant, then Tenant shall be entitled to deduct from Rent payable by Tenant under this Lease, the amount set forth in such invoice with interest. If, however, Landlord delivers to Tenant, within ten (10) business after receipt of Tenant’s invoice, a written objection to the payment of such invoice, setting forth with reasonable particularity Landlord’s reasons for its claim that such action did not have to be taken by Landlord or were not permitted to be taken by Tenant pursuant to the terms of this Lease or that the charges are excessive (in which case Landlord shall pay the amount it contends would not have been excessive), then Tenant shall not then be entitled to such deduction from Rent, and if so elected by Tenant shall be Tenant’s sole remedy for Landlord’s failure to pay such costs. On the other hand, Tenant may pursue a claim against Landlord for the balance of the amounts due, including interest at the Interest Rate. If Tenant prevails in such legal action, the amount of the final non-appealable award, together with interest at the Interest Rate, if not paid by Landlord within thirty (30) days, may be deducted by Tenant from the Rent next due and owing under this Lease.

ARTICLE 8

ADDITIONS AND ALTERATIONS

8.1 Landlord’s Consent to Alterations . Except for Cosmetic Alterations (defined below), Tenant may not make any improvements, alterations, additions or changes to the Premises or any electrical, mechanical, plumbing or HVAC facilities or systems pertaining to the Premises (collectively, the “ Alterations ”) without first procuring the prior written consent of Landlord to such Alterations, which consent shall be requested by Tenant not less than ten (10) business days prior to the commencement thereof, and which consent shall not be unreasonably withheld or conditioned by Landlord, provided Landlord shall only withhold its consent to any Alteration which would (i) violate any Applicable Laws, (ii) adversely affect (in the reasonable discretion of Landlord) or require any modification to the Base Building or void any warranty on any Base Building component or design, or (iii) affect (in the sole discretion of Landlord) the (a) exterior appearance of the Project (other than Tenant’s Signage, the approval of which is subject to the TCCs of Section  23.4.4 below), (b) appearance of the Common Areas, (c) quiet enjoyment of other tenants or occupants of the Project (other than to a de minimis extent), or (d) provision of services to other occupants of the Project (any such Alteration or Tenant Improvement described in items (i) through (iii) above shall be deemed to contain a “ Design Problem ”). Landlord shall respond to Tenant’s request for Landlord’s consent to an Alteration within five (5) business days. Notwithstanding the foregoing, Tenant shall be permitted to make Alterations following five (5) business days’ notice to Landlord, but without Landlord’s prior consent, to the extent that such Alterations do not (I) cause a Design Problem, or (II) cost more than $250,000.00 (any such Alterations are “ Cosmetic Alterations ”). To the extent that Landlord grants Tenant the right to use areas within the Project, whether pursuant to the terms of this Lease or through plans and specifications subsequently approved by Landlord (and without implying that Landlord shall grant any such approvals), (A) in no event may Tenant use more than Tenant’s Share of the areas within the Building or utility capacity made available by Landlord for general tenant usage for Tenant’s installations and operations in the Premises (including chilled water, electricity, telecommunications room space, electrical room space, plenum space and riser space), and (B) Tenant shall comply with the provisions of this Section with respect to all such items, including Tenant’s Off-Premises Equipment. The construction of the initial improvements to the Premises shall be governed by the terms of the Tenant Work Letter and not the terms of this Article  8 , except for the applicable terms of this Section  8.1 above and Section  8.5 below, which shall apply to the Tenant Improvements as set forth therein.

8.2 Manner of Construction . In connection with the construction of any Alterations, Tenant shall utilize only contractors reasonably approved by Landlord, and any removal and/or restoration obligations required to be performed pursuant to the TCCs of Section  8.5 of this Lease; provided, however, it shall not be reasonable for Landlord to withhold consent to a contractor proposed by Tenant if such contractor is licensed, bonded and insured and does work in Comparable Buildings. If Landlord shall give its consent, the consent shall be deemed conditioned upon Tenant acquiring a permit to do the work from appropriate governmental agencies, the furnishing of a copy of such permit to Landlord prior to the commencement of the work, and the compliance by Tenant with all conditions of said permit in a prompt and expeditious manner. If such Alterations will involve the use of or disturb hazardous materials or substances existing in the Premises, Tenant shall notify Landlord prior to performing such Alterations and comply with Landlord’s Rules and Regulations concerning such hazardous materials or substances. Tenant shall construct such Alterations and perform such repairs in a good and workmanlike manner, in conformance with any and all Applicable Laws and pursuant to a valid building permit, issued by the city in which the Building is located (or other applicable governmental authority), all in conformance with Landlord’s construction Rules and Regulations

and the Tenant Improvement Manual (as that term is defined in Section  2.3 of the Tenant Work Letter); provided, however, that prior to commencing to construct any Alteration, Tenant shall meet with Landlord to discuss Landlord’s design parameters and code compliance issues. In the event Tenant performs any Alterations in the Premises which require or give rise to governmentally required changes to the Base Building, as that term is defined below, then Landlord shall, at Tenant’s expense, make such changes to the Base Building. Since all or a portion of the Project may be certified under the LEED rating system as “silver” for Core & Shell, Tenant expressly acknowledges and agrees that without limitation as to other grounds for Landlord withholding its consent to any proposed Alteration, Landlord shall have the right to withhold its consent to any proposed Alteration in the event that such Alteration is not compatible with such certification of the Core & Shell under such LEED rating system. Tenant shall construct such Alterations and perform such maintenance and repairs in a good and workmanlike manner, in conformance with any and all Applicable Laws (including all applicable permits and consents issued with respect to the Alterations or maintenance and repairs) and pursuant to a valid building permit, issued by the City of Seattle, all in conformance with Landlord’s Rules and Regulations applicable to construction. All work under Section  7.1 above and this Article 8 which may affect the Base Building must be approved by the Project’s engineer of record, at Tenant’s expense, and if any work by Tenant affects or requires changes to the Base Building, then Landlord may elect, at Tenant’s expense, to make such changes. The “ Base Building ” shall mean the structural portions of the Building (including the roof, roof membrane, footings, foundations, structural portions of load-bearing walls, structural floors and subfloors, structural columns and beams and curtain walls), and the Common Area restrooms, elevators, exit stairwells (collectively, the “ Building Structure ”) and the Building Systems. The “ Building Systems ” shall mean the Building’s HVAC, life-safety, plumbing, electrical, mechanical and elevator systems. In performing any work under Section  7.1 above and this Article 8 , Tenant shall have the work performed in such manner so as not to damage the Building or unreasonably interfere with or obstruct access to the Project or any portion thereof, or business of Landlord or other tenants in the Project. Tenant shall use commercially reasonable efforts to not disturb labor harmony at the Project. In addition to Tenant’s obligations under Article 9 of this Lease, Tenant shall deliver to the Project construction manager an accurate reproducible copy of the “as built” drawings of the Alterations as well as all permits, approvals and other documents issued by any governmental agency in connection with the Alterations.

8.3 Payment by Tenant . If payment is made by Tenant directly to contractors, Tenant shall (i) comply with Landlord’s requirements for final lien releases and waivers in connection with Tenant’s payment for work to contractors, and (ii) sign Landlord’s standard contractor’s rules and regulations. If Tenant orders any work directly from Landlord, and Landlord agrees to perform such work, Tenant shall pay to Landlord a supervision fee equal to (i) three percent (3%) of the cost of such work, for the first $150,000 of such costs, (ii) two percent (2%) of the cost of such work, for such costs of more than $150,000 and up to $500,000, (iii) one percent (1%) of the cost of such work for such costs of more than $500,000. In addition, in all events, Tenant shall reimburse Landlord for Landlord’s reasonable, actual, out-of-pocket costs and expenses actually incurred in connection with Landlord’s review of any Alterations (other than Cosmetic Alterations); provided, however, that before incurring any such cost or expense, Landlord shall provide Tenant with an estimate of the same at least five (5) business days before incurring any such expense, during which five (5) business day period Tenant may withdraw its request for such Alterations. At Landlord’s option, prior to the commencement of construction of any Alteration, Tenant shall provide Landlord with the reasonably anticipated cost thereof, which Landlord shall disburse during construction pursuant to Landlord’s standard, commercially reasonable disbursement procedure.

8.4 Construction Insurance . In addition to the requirements of Article 10 of this Lease, during the performance of any Alterations and/or work performed under Section  7.1 above, Tenant shall carry or shall cause its contractors and subcontractors to carry “ Builder’s All Risk ” insurance (and shall provide Landlord with evidence of the same) in a commercially reasonable amount taking into account the nature and scope of the Alterations and work and with companies covering such Alterations that satisfy the requirements of Section  8.2 , and such other insurance and endorsements as Landlord may reasonably require consistent with the practices of the owners of Comparable Buildings. All Alterations shall be insured by Tenant pursuant to Article 10 of this Lease immediately upon completion thereof.

8.5 Landlord’s Property . All Alterations, improvements, fixtures (other than trade fixtures), and/or affixed equipment which may be installed or placed in or about the Premises, from time to time, shall, except as otherwise provided herein or in the Tenant Work Letter, be at the sole cost of Tenant and upon the expiration or termination of the Lease shall be and become the property of Landlord. Notwithstanding the foregoing, at the time Landlord approves any Alteration, Landlord shall be deemed to have required Tenant, at Tenant’s expense, to

remove any Specialty Improvements (as that term is defined below) within the Premises and to repair any damage to the Premises and Building caused by such removal, unless, in connection with its notice to Landlord with respect to any such Specialty Improvements (including any Tenant Improvements), or at any time thereafter (but not more than once in connection with any Alteration or Tenant Improvement), (i) Tenant requests Landlord’s decision with regard to the removal of such Specialty Improvements, such request to be made using the form attached hereto as Exhibit J (“ Tenant’s Removal Request ”), and (ii) Landlord thereafter agrees in writing to waive the removal requirement with regard to such Specialty Improvements, then Tenant shall not be required to so remove such Specialty Improvements. If Landlord consents to the Alteration, but fails to respond to Tenant’s Removal Request within ten (10) business days after receipt thereof and of electronic and hard copy versions of all plans relating to the applicable Alterations, then Tenant may send Landlord a reminder notice setting forth such failure containing the following sentence at the top of such notice in bold, capitalized font at least twelve (12) points in size: “ LANDLORD’S FAILURE TO RESPOND TO THIS NOTICE WITHIN FIVE (5)  BUSINESS DAYS SHALL RESULT IN LANDLORD’S DEEMED ELECTION TO NOT REQUIRE TENANT TO REMOVE THE SPECIFIED ALTERATIONS UPON THE EXPIRATION OF THE LEASE TERM ” (the “ Removal Reminder Notice ”). Any such Removal Reminder Notice shall also include a complete hard copy of Tenant’s plans and specification for such Alteration. If Landlord fails to respond within five (5) business days after receipt of a Removal Reminder Notice, then Landlord shall be deemed to have elected to not require Tenant to remove the specified approved Alteration upon expiration of the Lease Term. If Tenant fails to complete any removal and/or to repair any damage caused by the removal of any Specialty Improvements that are required to be removed pursuant to this Lease, Landlord may do so and may charge the cost thereof to Tenant. Tenant hereby protects, defends, indemnifies and holds Landlord harmless from any liability, cost, obligation, expense or claim of lien in any manner relating to the performance of any work under this Article  8 or installation, placement, removal or financing of any such Alterations, improvements, fixtures and/or equipment in, on or about the Premises, which obligations of Tenant shall survive the expiration or earlier termination of this Lease. “ Specialty Improvements ” means any Alterations or Tenant Improvements other than normal and customary general office improvements. Notwithstanding the foregoing, “ Specialty Improvements ” (i) shall not include conference rooms, training space, Cosmetic Alterations, Lines (as that term is defined in Section  29.32 below), and any private/internal stairways constructed in the Premises as part of the Tenant Improvements and (ii) shall include (a) the Fitness Center, (b) any kitchens, showers, restrooms (excluding restrooms installed by Landlord as part of the Base, Shell and Core, as that term is defined in Section  1.1 of the Tenant Work Letter), washrooms or similar facilities in the Premises that are not part of the Base Building, (c) any Alterations or Tenant Improvements made by, or on behalf of Tenant to the Office Lobby, and (d) any Tenant Change Items, as that term is defined in the Tenant Work Letter.

8.6 Landlord’s Permit Obligations . At Tenant’s sole cost and expense, throughout the Lease Term, Landlord shall maintain on file with the City of Seattle, current plans for the Building and Project, as necessary for Landlord to maintain a blanket permit for the Building and Project. Upon request, Tenant shall provide Landlord with any information relating to the Tenant Improvements, any Alterations, and the Premises, required to satisfy the foregoing obligation.

ARTICLE 9

COVENANT AGAINST LIENS

Tenant shall keep the Project and Premises free from any liens or encumbrances arising out of the work performed, materials furnished or obligations incurred by or on behalf of Tenant, and shall protect, defend, indemnify and hold Landlord harmless from and against any claims, liabilities, judgments or costs (including, without limitation, reasonable attorneys’ fees and costs) arising out of same or in connection therewith. Tenant shall remove any such lien or encumbrance within ten (10) business days after notice by Landlord, and if Tenant shall fail to do so, Landlord may pay the amount necessary to remove such lien or encumbrance, without being responsible for investigating the validity thereof; provided, however, Tenant shall have the right to contest any such liens or encumbrances, and accordingly if Tenant is in the process of contesting the same, Tenant may bond around such lien or encumbrance, rather than paying amounts to remove the same. The amount so paid shall be deemed Additional Rent under this Lease payable upon demand, without limitation as to other remedies available to Landlord under this Lease. Nothing contained in this Lease shall authorize Tenant to do any act which shall subject Landlord’s title to the Building or Premises to any liens or encumbrances whether claimed by operation of law or express or implied contract. Any claim to a lien or encumbrance upon the Building or Premises arising in connection with any such work or respecting the Premises not performed by or at the request of Landlord shall be null and void, or at Landlord’s option shall attach only against Tenant’s interest in the Premises and shall in all respects be subordinate to Landlord’s title to the Project, Building and Premises.

ARTICLE 10

INDEMNIFICATION AND INSURANCE

10.1 Indemnification and Waiver . Tenant hereby assumes all risk of damage to property or injury to persons in, upon or about the Premises from any cause whatsoever and agrees that Landlord, its partners, subpartners and their respective officers, agents, servants, employees, and independent contractors (collectively, “ Landlord Parties ”) shall not be liable for, and are hereby released from any responsibility for, any damage either to person or property or resulting from the loss of use thereof, which damage is sustained by Tenant or by other persons claiming through Tenant, except to the extent of the negligence or willful misconduct of the Landlord Parties or the breach of this Lease by the Landlord Parties. Except to the extent of the negligence or willful misconduct of the Landlord Parties or breach of this Lease by the Landlord Parties, Tenant shall indemnify, defend, protect, and hold harmless the Landlord Parties from and against any and all loss, cost, damage, expense and liability (including without limitation court costs and reasonable attorneys’ fees) incurred in connection with or arising from: (a) any causes in, on or about the Premises or Tenant’s Off-Premises Equipment; (b) any activity, work, or thing done, or permitted or suffered by Tenant in or about the Premises or Tenant’s Off-Premises Equipment or relating to Tenant’s actions taken under Section  7.3 above, provided that the terms of the foregoing indemnity shall not apply to the extent of third party claims against Landlord that would have existed absent the actions undertaken by Tenant under Section  7.3 , above; (c) any negligence or willful misconduct of Tenant or any person claiming under Tenant, or the contractors, agents, employees, invitees, or visitors of Tenant, any Third Party Operator, or any such person, in, on or about the Project (collectively, “ Tenant Parties ”); (d) any breach of the terms of this Lease by any Tenant Party; and (e) the placement of any personal property or other items within the Premises. Landlord shall indemnify, defend, protect, and hold harmless Tenant from and against any and all loss, cost, damage, expense and liability (including, without limitation, court costs and reasonable attorneys’ fees) incurred in connection with or arising from (i) the negligence or willful misconduct of the Landlord Parties related to this Lease or the Project or (ii) breach of this Lease by the Landlord Parties, either prior to or during the Lease Term, except to the extent caused by the negligence or willful misconduct of the Tenant Parties or breach of this Lease by the Tenant Parties. Tenant’s agreement to indemnify Landlord and Landlord’s agreement to indemnify Tenant pursuant to this Section  10.1 are not intended to and shall not relieve any insurance carrier of its obligations under policies required to be carried pursuant to the provisions of this Lease, to the

extent such policies cover, or if carried, would have covered the matters, subject to the parties’ respective indemnification obligations; nor shall they supersede any inconsistent agreement of the parties set forth in any other provision of this Lease. Landlord and Tenant each hereby agrees that it shall not assert any industrial insurance immunity rights pursuant to Title 51 RCW (as the same may be amended, substituted or replaced) if such assertion would be inconsistent with or otherwise impair Tenant’s or Landlord’s, as the case may be, right to indemnification under this Section  10.1 , and, accordingly, each hereby waives all such industrial insurance immunity rights. The foregoing waiver of industrial insurance immunity rights was specifically negotiated by Landlord and Tenant and is solely for the benefit of the Landlord and Tenant, and their successors and assigns, under the Lease, and is not intended as a waiver of Landlord’s or Tenant’s rights of immunity under such industrial insurance for any other purposes. The provisions of this Section  10.1 shall survive the expiration or sooner termination of this Lease with respect to any claims or liability arising in connection with any event occurring prior to such expiration or termination.

10.2 Tenant’s Compliance With Landlord’s Fire and Casualty Insurance . Tenant shall, at Tenant’s expense and after reasonable prior notice of the same (which shall be not less than thirty (30) days), comply with Landlord’s insurance company requirements pertaining to the use of the Premises. If Tenant’s conduct or use of the Premises for any use other than the Standard Permitted Use causes any increase in the premium for such insurance policies, then Tenant shall reimburse Landlord for any such increase. Tenant, at Tenant’s expense, shall comply with all rules, orders, regulations or requirements of the American Insurance Association (formerly the National Board of Fire Underwriters) and with any similar body. Landlord will not obtain any insurance that would prohibit the conduct of business from the Premises for the Standard Permitted Use.

10.3 Tenant’s Insurance . Throughout the Lease Term, Tenant shall maintain the following coverages in the following amounts. The required evidence of coverage must be delivered to Landlord on or before the date required under Section 10.4(I) sub-sections (x)  and (y) , or Section  10.4(II) below (as applicable). Such policies shall be for a term of at least one (1) year, or the length of the remaining term of this Lease, whichever is less.

10.3.1 Commercial General Liability Insurance, including Broad Form contractual liability covering the insured against claims of bodily injury, personal injury and property damage (including loss of use thereof) based upon or arising out of Tenant’s operations, occupancy or maintenance of the Project and all areas appurtenant thereto. Such insurance shall be written on an “occurrence” basis. Landlord and any other party the Landlord so specifies that has a material financial interest in the Project, including Landlord’s managing agent, ground lessor and/or lender, if any, shall be named as additional insureds as their interests may appear using Insurance Service Organization’s form CG2011 or a comparable form approved by Landlord. Tenant shall provide an endorsement or policy excerpt showing that Tenant’s coverage is primary and any insurance carried by Landlord shall be excess and non-contributing. The coverage shall also be extended to include damage caused by heat, smoke or fumes from a hostile fire. The policy shall not contain any intra-insured exclusions as between insured persons or organizations. This policy shall include coverage for all liabilities assumed under this Lease as an insured contract for the performance of all of Tenant’s indemnity obligations under this Lease. The limits of said insurance shall not, however, limit the liability of Tenant nor relieve Tenant of any obligation hereunder. Limits of liability insurance shall not be less than the following; provided, however, such limits may be achieved through the use of an Umbrella/Excess Policy:

10.3.2 Property Insurance covering (i) all office furniture, personal property, business and trade fixtures, office equipment, free-standing cabinet work, movable partitions, merchandise and all other items of Tenant’s business personal property on the Premises installed by, for, or at the expense of Tenant, (ii) the Tenant Improvements, and (iii) all Alterations performed in the Premises. Such insurance shall be written on a Special Form basis, for the full replacement cost value (subject to reasonable deductible amounts), without deduction for depreciation of the covered items and in amounts that meet any co-insurance clauses of the policies of insurance and shall include coverage for (a) all perils included in the CP 10 30 04 02 Coverage Special Form, (b) water damage from any cause whatsoever, including, but not limited to, sprinkler leakage, bursting, leaking or stoppage of any pipes, explosion, and backup or overflow from sewers or drains, and (c) terrorism (to the extent such terrorism insurance is available as a result of the Terrorism Risk Insurance Act of 2002 (Pub. L. 107-297, 116 Stat. 2322), the Terrorism Risk Insurance Program Reauthorization Act of 2005 (Pub. l. 109-144), and the Terrorism Risk Insurance Program Reauthorization Act of 2007 (Pub. L. 110-160, 121 Stat. 183), any successor statute or regulation, or is otherwise available at commercially reasonable rates).

10.3.2.1 No Representation of Adequate Coverage . Landlord makes no representation that the limits or forms of coverage of insurance specified herein are adequate to cover Tenant’s property, business operations or obligations under this Lease.

10.3.2.2 Property Insurance Subrogation . Landlord and Tenant intend that their respective property loss risks shall be borne by insurance carriers to the extent above provided (and, in the case of Tenant, by an insurance carrier satisfying the requirements of Section  10.4(i) below), and Landlord and Tenant hereby agree to look solely to, and seek recovery only from, their respective insurance carriers in the event of a property loss to the extent that such coverage is agreed to be provided hereunder. The parties each hereby waive all rights and claims against each other for such losses, and waive all rights of subrogation of their respective insurers. Landlord and Tenant hereby represent and warrant that their respective “all risk” property insurance policies include a waiver of (i) subrogation by the insurers, and (ii) all rights based upon an assignment from its insured, against any of the Landlord Parties or any of the Tenant Parties (as the case may be) in connection with any property loss risk thereby insured against. Tenant will cause all subtenants and licensees of the Premises claiming by, under, or through Tenant to execute and deliver to Landlord a waiver of claims similar to the waiver in this Section  10.3.2.2 and to obtain such waiver of subrogation rights endorsements. If either party hereto fails to maintain the waivers set forth in items (i) and (ii) above, the party not maintaining the requisite waivers shall indemnify, defend, protect, and hold harmless the other party for, from and against any and all claims, losses, costs, damages, expenses and liabilities (including, without limitation, court costs and reasonable attorneys’ fees) arising out of, resulting from, or relating to, such failure.

10.3.3 Business Income Interruption for six (6) months.

10.3.4 Worker’s Compensation or other similar insurance pursuant to all applicable state and local statutes and regulations, and Employer’s Liability with minimum limits of not less than $1,000,000 each accident/employee/disease.

10.3.5 Commercial Automobile Liability Insurance covering all Owned (if any), Hired, or Non-owned vehicles with limits not less than $1,000,000 combined single limit for bodily injury and property damage.

10.4 Form of Policies . The minimum limits of policies of insurance required of Tenant under this Lease shall in no event limit the liability of Tenant under this Lease. Such insurance shall (i) be issued by an insurance company having an AM Best rating of not less than A-X (or to the extent AM Best ratings are no longer available, then a similar rating from another comparable rating agency), or which is otherwise acceptable to Landlord and licensed to do business in the State of Washington, (ii) be in form and content reasonably acceptable to Landlord and complying with the requirements of Section  10.3 (including, Sections 10.3.1 through 10.3.5 ), (iii) Tenant shall not do or permit to be done anything which invalidates the required insurance policies, and (iv) provide that said insurance shall not be canceled or coverage changed unless thirty (30) days’ prior written notice shall have been given to Landlord and any mortgagee of Landlord, the identity of whom has been provided to Tenant in writing. Tenant shall deliver said policy or policies or certificates thereof and applicable endorsements which meet the requirements of this Article  10 to Landlord on or before (I) the earlier to occur of: (x) the Lease Commencement Date, and (y) the date Tenant and/or its employees, contractors and/or agents first enter the Premises for occupancy, construction of improvements, alterations, or any other move-in activities, and (II) five (5)

business days after the renewal of such policies. In the event Tenant shall fail to procure such insurance, or to deliver such policies or certificates and applicable endorsements, Landlord may, at its option, after written notice to Tenant and Tenant’s failure to obtain such insurance within five (5) days thereafter, procure such policies for the account of Tenant and the sole benefit of Landlord, and the cost thereof shall be paid to Landlord after delivery to Tenant of bills therefor.

10.5 Additional Insurance Obligations . After the expiration of the initial Lease Term, Landlord shall have the right to require Tenant to carry and maintain during the entire Lease Term, at Tenant’s sole cost and expense, increased amounts of the insurance and such other reasonable types of insurance coverage and in such reasonable amounts covering the Premises and Tenant’s operations therein, as may be consistent with the requirements of landlords of Comparable Buildings.

10.6 Third-Party Contractors . Tenant shall obtain and deliver to Landlord, Third Party Contractor’s certificates of insurance and applicable endorsements at least seven (7) business days prior to the commencement of work in or about the Premises by any vendor or any other third-party contractor (collectively, a “ Third Party Contractor ”). All such insurance shall (i) name Landlord as an additional insured under such party’s liability policies as required by Section  10.3.1 above and this Section  10.6 , (ii) provide a waiver of subrogation in favor of Landlord under such Third Party Contractor’s commercial general liability insurance, (iii) be primary and any insurance carried by Landlord shall be excess and non-contributing, and (iv) be of types, and in amounts, that are commercially reasonable, taking into consideration the type and cost of work to be performed by the Third Party Contractor.

10.7 Landlord’s Insurance . Landlord shall carry commercial general liability insurance with respect to the Building during the Lease Term, and shall further insure the Building and the Project during the Lease Term against loss or damage due to fire and other casualties covered within the classification of fire and extended coverage, vandalism coverage and malicious mischief, sprinkler leakage, water damage and special extended coverage. Such coverage shall be in such amounts, from such companies, and on such other terms and conditions, as Landlord may from time to time reasonably determine, consistent with the practices of institutional owners of Comparable Buildings. Additionally, at the option of Landlord, such insurance coverage may include the risks of earthquakes and/or flood damage, terrorist acts and additional hazards, a rental loss endorsement and one or more loss payee endorsements in favor of the holders of any mortgages or deeds of trust encumbering the interest of Landlord in the Building or the ground or underlying lessors of the Building, or any portion thereof. Notwithstanding the foregoing provisions of this Section  10.7 , the coverage and amounts of insurance carried by Landlord in connection with the Building shall, at a minimum, be comparable to the types of coverage and limits and deductible amounts of insurance which are carried by reasonably prudent landlords of Comparable Buildings (provided that in no event shall Landlord be required to carry earthquake or terrorism insurance), and Worker’s Compensation and Employer’s Liability coverage as required by Applicable Laws. Notwithstanding anything contained herein to the contrary, Landlord shall carry commercially reasonable earthquake insurance to the extent the same is commercially reasonably available upon commercially reasonable terms.

ARTICLE 11

DAMAGE AND DESTRUCTION

11.1 Repair of Damage to Premises by Landlord . If the Base Building or any Common Areas serving or providing access to the Premises shall be damaged by a fire or any other casualty (collectively, a “Casualty”), Landlord shall promptly and diligently, subject to reasonable delays Force Majeure (as defined in Section  29.16 below), and subject to all other terms of this Article  11 , restore the Base Building and such Common Areas. Such restoration shall be to substantially the same condition of the Base Building and the Common Areas prior to the Casualty, except for modifications required by Applicable Laws or required by the holder of a mortgage on the Building or Project in accordance with the applicable loan documents or any other modifications to the Common Areas deemed desirable by Landlord, subject to Section  1.1.4 above, which are consistent with the Class A Standard, provided that (i) access to the Premises, (ii) such changes shall not adversely affect the quality and functionality of services (for example only, without limitation, the availability of, and service level of, utilities and the BB HVAC System). Tenant shall promptly notify Landlord upon the occurrence of any damage to the Premises resulting from a Casualty, and Tenant shall promptly inform its insurance carrier of any such damage. Upon notice (the “ Landlord Repair Notice ”) to Tenant from Landlord in connection with a Casualty that materially affects the

Base Building and the Common Areas, as well as the Premises, Tenant shall assign to Landlord (or to any party designated by Landlord) all insurance proceeds payable to Tenant under Tenant’s insurance required under Section  10.3.2(ii) and (iii)  of this Lease, and Landlord shall repair any injury or damage to the Tenant Improvements and the Alterations installed in the Premises and shall return such Tenant Improvements and the Alterations to their original condition; provided that if the cost of such repair by Landlord shall exceed the amount of insurance proceeds received by Landlord from Tenant’s insurance carrier, as assigned by Tenant, at Tenant’s option, upon notice to Landlord within thirty (30) days following receipt of notice from Landlord that the proceeds of Tenant’s insurance are anticipated to be insufficient, Tenant may elect either (a) to perform all repairs to the Tenant Improvements and Alterations, at Tenant’s cost, (b) to modify the Tenant Improvements and Alterations to reduce the cost of repairs and have Landlord proceed to make such repairs, provided that (I) Tenant shall pay, prior to the commencement of repair of the damage, the amount of any insufficiency in insurance proceeds (if the same shall exist), (II) any changes shall be consistent with the Class A Standard and shall be subject to the reasonable approval of Landlord, and (III) Tenant’s abatement of Rent hereunder shall terminate as of the date repairs would have been completed by Landlord absent such changes by Tenant, or (c) require Landlord to perform repairs without Tenant changes, in which event the cost of such repairs shall be paid by Tenant to Landlord prior to Landlord’s commencement of repair of the damage. In the event that Landlord does not deliver the Landlord Repair Notice within sixty (60) days following the date the Casualty becomes known to Landlord or in the event the Casualty only materially affects the Premises, Tenant shall, at its sole cost and expense, repair any injury or damage to the Tenant Improvements and the Alterations installed in the Premises and shall return such Tenant Improvements and Alterations to their original condition. Whether or not Landlord delivers a Landlord Repair Notice, prior to the commencement of construction, Tenant shall submit to Landlord, for Landlord’s review and approval, all plans, specifications and working drawings relating thereto. In the event that Landlord shall perform the repairs to the Tenant Improvements and Alterations hereunder, Landlord shall select the contractors to perform such improvement work. In the event that Tenant shall perform the repairs to the Tenant Improvements and Alterations hereunder, Tenant shall select the contractor to perform the work, provided that such contractor shall be subject to Landlord’s approval, which shall not be unreasonably withheld, conditioned or delayed. Landlord shall not be liable for any inconvenience or annoyance to Tenant or its visitors, or injury to Tenant’s business resulting in any way from such damage or the repair thereof; provided however, that if such Casualty shall have damaged the Premises or Critical Common Areas, and the Premises is used by Tenant for the Permitted Use as a result thereof, then during the time and to the extent the Premises is not used for the Permitted Use, the Rent shall be abated in proportion to the ratio that the amount of rentable square feet of the Premises which is not used by Tenant for the Permitted Use bears to the total rentable square feet of the Premises. In the event that Landlord shall not deliver the Landlord Repair Notice, Tenant’s right to rent abatement pursuant to the preceding sentence shall terminate as of the date which Tenant should have completed repairs to the Premises assuming Tenant used reasonable due diligence in connection therewith.

11.2 Landlord’s and Tenant’s Termination Rights .

11.2.1 Landlord’s Termination Rights . Notwithstanding the terms of Section  11.1 of this Lease, Landlord may elect not to rebuild and/or restore the Premises, Building and/or Project, and instead terminate this Lease, by notifying Tenant in writing of such termination within sixty (60) days after the date of discovery of the damage, such notice to include a termination date giving Tenant sixty (60) days to vacate the Premises, but Landlord may so elect only if the Building or Project shall be damaged by Casualty, and if the Premises is also affected, and one or more of the following conditions is present: (i) repairs cannot reasonably be completed within two hundred seventy (270) days after the date of the Casualty (when such repairs are made without the payment of overtime or other premiums); (ii) the holder of any mortgage on the Building or Project requires that the insurance proceeds or any portion thereof be used to retire the mortgage debt, in accordance with the terms of the loan documents; (iii) provided that Landlord maintains the insurance required pursuant to the terms of Section  10.7 of this Lease, the damage is not fully covered, except for the Landlord Contribution (as that term is defined below) by Landlord’s insurance policies; (iv) the damage occurs during the last twelve (12) months of the Lease Term. For purposes hereof, the “ Landlord Contribution ” shall mean $2,000,000.

incurring material expense, including by reason of loss of access or inability to use the Parking Garage, and either (a) the repairs cannot be completed within two hundred seventy (270) days after the date of the Casualty or (b) the damage occurs during the last twelve (12) months of the Lease Term, Tenant may elect, no earlier than sixty (60) days after receipt of Landlord’s Repair Estimate Notice and not later than ninety (90) days after receipt of Landlord’s Repair Estimate Notice, to terminate this Lease by written notice to Landlord effective as of the date specified in the notice, which date shall not be less than thirty (30) days nor more than sixty (60) days after the date such notice is given by Tenant. At any time, from time to time, after the date occurring sixty (60) days after the date of the damage, Tenant may request that Landlord inform Tenant of Landlord’s reasonable opinion of the date of completion of the repairs and Landlord shall respond to such request within five (5) business days (“ Landlord’s Repair Estimate Notice ”). Furthermore, if neither Landlord nor Tenant has terminated this Lease, and the repairs are not actually completed within ninety (90) days following the anticipated date of completion set forth in Landlord’s Repair Estimate Notice, Tenant shall have the right to terminate this Lease during the first ten (10) business days following the expiration of such ninety (90) day period, by notice to Landlord (the “ Damage Termination Notice ”), effective as of a date set forth in the Damage Termination Notice (the “ Damage Termination Date ”), which Damage Termination Date shall not be less than thirty (30) days and not more than sixty (60) days following delivery of such notice.

11.3 Waiver of Statutory Provisions . The provisions of this Lease, including this Article  11 , constitute an express agreement between Landlord and Tenant with respect to any and all damage to, or destruction of, all or any part of the Premises, the Building or the Project, and any statute or regulation of the State of Washington, with respect to any rights or obligations concerning damage or destruction in the absence of an express agreement between the parties, and any other statute or regulation, now or hereafter in effect, shall have no application to this Lease or any damage or destruction to all or any part of the Premises, the Building or the Project.

ARTICLE 12

NONWAIVER

No provision of this Lease shall be deemed waived by either party hereto unless expressly waived in a writing signed thereby. The waiver by either party hereto of any breach of any TCC herein contained shall not be deemed to be a waiver of any subsequent breach of same or any other TCC herein contained. The subsequent acceptance of Rent hereunder by Landlord shall not be deemed to be a waiver of any preceding breach by Tenant of any term, covenant or condition of this Lease, other than the failure of Tenant to pay the particular Rent so accepted, regardless of Landlord’s knowledge of such preceding breach at the time of acceptance of such Rent. No acceptance of a lesser amount than the Rent herein stipulated shall be deemed a waiver of Landlord’s right to receive the full amount due, nor shall any endorsement or statement on any check or payment or any letter accompanying such check or payment be deemed an accord and satisfaction, and Landlord may accept such check or payment without prejudice to Landlord’s right to recover the full amount due. No receipt of monies by Landlord from Tenant after the termination of this Lease shall in any way alter the length of the Lease Term or of Tenant’s right of possession hereunder, or after the giving of any notice shall reinstate, continue or extend the Lease Term or affect any notice given Tenant prior to the receipt of such monies, it being agreed that after the service of notice or the commencement of a suit, or after final judgment for possession of the Premises, Landlord may receive and collect any Rent due, and the payment of said Rent shall not waive or affect said notice, suit or judgment.

ARTICLE 13

CONDEMNATION

13.1 Total Taking . If the whole of the Premises, Building or Project shall be taken by power of eminent domain or condemned by any competent authority for any public or quasi-public use or purpose, or if Landlord shall grant a deed or other instrument in lieu of such taking by eminent domain or condemnation of the whole of the Premises, Building or Project, this Lease shall terminate effective as of the date possession is required to be surrendered to the authority, and Landlord shall give Tenant notice of such termination not later than thirty (30) days after the order for the taking is entered by a court of competent jurisdiction.

13.2 Partial Taking . (i) If more than twenty-five percent (25%) of the rentable square feet of the Premises is taken on a non-temporary basis, or (ii) if access to the Premises, including access to the Office Elevators is materially impaired, or (iii) access to, and use of, the Parking Garage, is materially impaired (and Landlord has not made reasonably comparable parking available to Tenant in reasonable proximity to the Building), then in any such event, Tenant shall have the option to terminate this Lease effective as of the date possession is required to be surrendered to the authority. Landlord shall give prompt notice to Tenant of any order for the taking entered by a court of competent jurisdiction, and the parties shall have thirty (30) days after delivery of Landlord’s notice to exercise the foregoing termination rights. If a party having the right to terminate this Lease under this Section  13.2 fails to give such notice of termination within such thirty (30) day period, such right shall be deemed waived and this Lease shall remain in full force and effect. Tenant shall not because of such taking assert any claim against Landlord or the authority for any compensation because of such taking and Landlord shall be entitled to the entire award or payment in connection therewith, except that Tenant shall have the right to file any separate claim available to Tenant for any taking of Tenant’s personal property and fixtures belonging to Tenant and removable by Tenant upon expiration of the Lease Term pursuant to the terms of this Lease, and for moving expenses, so long as such claims do not diminish the award available to Landlord, its ground lessor with respect to the Building or Project or its mortgagee, and such claim is payable separately to Tenant. All Rent shall be apportioned as of the date of such termination. If any part of the Premises is taken, and this Lease shall not be so terminated, (a) the Rent shall be abated in proportion to the ratio that the amount of rentable square feet of the Premises which has been taken (or which is not usable for the Permitted Use, without taking extraordinary measures or incurring material expense, as a result of taking bears to the total rentable square feet of the Premises, as a result of the taking) bears to the total rentable square feet of the Premises, and (b) Landlord at its expense, shall restore the remainder of the Base Building, the Premises, the Tenant Improvements, any Alterations, and the Common Areas in accordance with Section  13.5 below. Tenant hereby affirms that all condemnation proceeds applicable to the Base Building, Premises, Tenant Improvements, any subsequent Alterations and Common Areas shall be the sole and exclusive property of Landlord.

13.3 Temporary Taking . Notwithstanding anything to the contrary contained in this Article  13 , in the event of a temporary taking of all or any portion of the Premises, then this Lease shall not terminate but the Base Rent and the Additional Rent shall be abated for the period of such taking in proportion to the ratio that the amount of rentable square feet of the Premises taken or which is not usable for the Permitted Use, without taking extraordinary measures or incurring material expense, as a result of taking bears to the total rentable square feet of the Premises. Landlord shall be entitled to receive the entire award made in connection with any such temporary taking.

13.4 Required Notices . If Landlord shall receive written notice from a governmental authority stating such authority’s intent to take all of any portion of the Building or Critical Common Areas, Landlord shall (i) within ten (10) business days after receiving such notice, give Tenant a copy thereof and (ii) upon request, meet with Tenant within sixty (60) days after receiving such notice, to discuss the potential taking, including the likelihood of the taking proceeding, whether Landlord (or, to Landlord’s knowledge, the owner of the portion of the Project affected by the taking, if other than Landlord) will or will not contest such taking, and whether such taking may give rise to either party’s right to terminate this Lease under any of the provisions of this Article  13 . If, at any point in the course of a taking, Landlord determines that it will not contest the taking (or if Landlord obtains actual knowledge that the owner of the affected portion of the Project, if other than Landlord, will not contest the taking), Landlord shall promptly give Tenant notice of such determination.

13.5 Obligation to Restore . If this Lease is not terminated as provided in this Article 13 , Landlord shall, at its sole expense, restore with due diligence the affected portions of the Base Building, the Premises, the Tenant Improvements, any Alterations, and the Common Areas, so far as is practicable to a complete unit of like quality, character, and condition as that which existed immediately prior to the taking, provided that (i) Landlord shall not be obligated to expend an amount greater than that which was awarded to Landlord for such taking, plus any portion of Tenant’s award made available by Tenant to Landlord for restoration, (ii) Landlord shall not be required to restore Tenant Improvements or Alterations made by or on behalf of Tenant, including, without limitation, any of Tenant’s signage, the Rooftop Equipment (as defined in Section  21.1 below), the Generator, the Lobby Desk, or Tenant’s personal property unless and except to the extent the award received by Landlord was in compensation for the taking of such items or Tenant makes available to Landlord for the restoration of such items a portion of its award sufficient to pay for the restoration thereof, and (iii) if Landlord fails to complete such

restoration within two hundred seventy (270) days after the date on which title to the property subject to the taking is transferred to the governmental authority, Tenant may terminate this Lease by written notice given to Landlord within thirty (30) days following the expiration of such two hundred seventy (270) day period, and Tenant’s failure to delivery such notice within such time period, shall constitute Tenant’s waiver of its termination right set forth in this Section  13.5 . Tenant, at its sole cost and expense, shall restore its furniture, fixtures and other allowed leasehold improvements in such manner as Tenant elects, subject to the terms of this Lease.

ARTICLE 14

Tenant shall not, without the prior written consent of Landlord, assign, mortgage, pledge, hypothecate, encumber, or permit any lien to attach to, or otherwise transfer, this Lease or any interest hereunder, permit any assignment, or other transfer of this Lease or any interest hereunder by operation of law, sublet the Premises or any part thereof, or enter into any license or concession agreements or otherwise permit the occupancy or use of the Premises or any part thereof by any persons other than Tenant and its employees and contractors (all of the foregoing are hereinafter sometimes referred to collectively as “ Transfers ” and any person or entity to whom any Transfer is made or sought to be made is hereinafter sometimes referred to as a “ Transferee ”). If Tenant desires Landlord’s consent to any Transfer, Tenant shall notify Landlord in writing, which notice (the “ Transfer Notice ”) shall include (i) the proposed effective date of the Transfer, which shall not be less than thirty (30) days nor more than one hundred eighty (180) days after the date of delivery of the Transfer Notice, (ii) a description of the portion of the Premises to be transferred (the “ Subject Space ”), (iii) a copy of the operative document effecting the proposed Transfer, (iv) the calculation of the Transfer Premium, as that term is defined in Section  14.3 below, in connection with such Transfer, if any, (v) the name and address of the proposed Transferee, and (vi) in connection with a sublease of less than a full floor of the Premises, current financial statements of the proposed Transferee certified by an officer, partner or owner thereof. In connection with items (iii) and (iv) above, Landlord shall execute, at Tenant’s request, a commercially reasonable confidentiality and nondisclosure agreement prior to receipt of the documentation provided for therein. Any Transfer made without Landlord’s prior written consent shall, at Landlord’s option, be null, void and of no effect, and shall, at Landlord’s option, constitute a default by Tenant under this Lease. Whether or not Landlord consents to any proposed Transfer, Tenant shall pay Landlord’s reasonable review and processing fees, as well as any reasonable professional fees (including, without limitation, attorneys’, accountants’, architects’, engineers’ and consultants’ fees) incurred by Landlord, within thirty (30) days after written request by Landlord; provided, however, that in no event shall such fees exceed $2,000.00 in connection with a single Transfer (so long as no material amendment to this Lease is required in connection therewith).

14.2 Landlord’s Consent . Landlord shall not unreasonably withhold, condition or delay its consent to any proposed Transfer of the Subject Space to the Transferee on the terms specified in the Transfer Notice. Without limitation as to other reasonable grounds for withholding consent, the parties hereby agree that it shall be reasonable under this Lease and under any applicable law for Landlord to withhold consent to any proposed Transfer where one or more of the following apply:

14.2.1 The Transferee is of a character or reputation or engaged in a business which is not consistent with the Class A Standard;

14.2.2 The Transferee intends to use the Subject Space for purposes which are not permitted under this Lease;

14.2.3 The Transferee is either a governmental agency or instrumentality thereof;

14.2.4 The Transferee is not a party of reasonable financial worth and/or financial stability in light of the rent and other monetary obligations of the Transferee under the applicable sublease or assignment affecting the Transfer, as determined on the date consent is requested; or

14.2.5 Either the proposed Transferee, or any person or entity which directly or indirectly, controls, is controlled by, or is under common control with, the proposed Transferee is negotiating with Landlord or has negotiated with Landlord during the three (3)-month period immediately preceding the date Landlord receives the Transfer Notice to lease space in the Project.

If Landlord consents to any Transfer pursuant to the terms of this Section  14.2 , Tenant may within twelve (12) months after Landlord’s consent, but not later than the expiration of said twelve (12)-month period, enter into such Transfer of the Premises or portion thereof, upon substantially the same terms and conditions as are set forth in the Transfer Notice furnished by Tenant to Landlord pursuant to Section  14.1 of this Lease, provided that if there are any changes in the terms and conditions of the Transfer from those specified in the Transfer Notice such that Landlord would initially have been entitled to refuse its consent to such Transfer under this Section  14.2 , Tenant shall again submit the Transfer to Landlord for its approval and other action under this Article  14 . Notwithstanding anything to the contrary in this Lease, if Tenant or any proposed Transferee claims that Landlord has unreasonably withheld, conditioned or delayed its consent under this Section  14.2 or otherwise has breached or acted unreasonably under this Article  14 , their sole remedies shall be a suit for contract damages (other than damages for injury to, or interference with, Tenant’s business including, without limitation, loss of profits, however occurring) or declaratory judgment and an injunction for the relief sought, and Tenant hereby waives all other remedies, including, without limitation, any right at law or equity to terminate this Lease, on its own behalf and, to the extent permitted under all Applicable Laws, on behalf of the proposed Transferee.

14.3 Transfer Premium . If Landlord consents to a Transfer, as a condition thereto which the parties hereby agree is reasonable, Tenant shall pay to Landlord twenty-five percent (25%) of any “Transfer Premium,” as that term is defined in this Section  14.3 , received by Tenant from such Transferee. “ Transfer Premium ” shall mean all rent, additional rent or other consideration payable by such Transferee in connection with the Transfer in excess of the Rent payable by Tenant under this Lease during the term of the Transfer on a per rentable square foot basis if less than all of the Premises is transferred, after deducting the reasonable expenses incurred by Tenant for (i) any changes, alterations and improvements to the Premises in connection with the Transfer, (ii) any free base rent, free additional rent, improvement allowances or other economic concessions reasonably provided to the Transferee, and (iii) any brokerage commissions, and accountants’ and attorneys’ fees paid in connection with the Transfer. “Transfer Premium” shall also include, but not be limited to, key money, bonus money or other cash consideration paid by Transferee to Tenant in connection with such Transfer, and any payment in excess of fair market value for services rendered by Tenant to Transferee or for assets, fixtures, inventory, equipment, or furniture transferred by Tenant to Transferee in connection with such Transfer; provided, however, that, in no event shall the Transfer Premium include proceeds related to a sale of any portion of Tenant’s business, including any Transfer to a Permitted Transferee pursuant to Section  14.8 below, regardless of whether such Permitted Transferee satisfies the other requirements of a Permitted Transfer pursuant to Section  14.8 below. The determination of the amount of Landlord’s applicable share of the Transfer Premium shall be made on a monthly basis as rent or other consideration is received by Tenant in connection with the Transfer.

14.4 Intentionally Omitted .

14.5 Effect of Transfer . If Landlord consents to a Transfer, (i) the TCCs of this Lease shall in no way be deemed to have been waived or modified, (ii) such consent shall not be deemed consent to any further Transfer by either Tenant or a Transferee, (iii) Tenant shall deliver to Landlord, promptly after execution, an original executed copy of the operative assignment agreement, sublease, or other document effecting the Transfer, (iv) Tenant shall furnish upon Landlord’s request a complete statement, certified by an independent certified public accountant, or Tenant’s chief financial officer or another qualified officer of Tenant, setting forth in detail the computation of any Transfer Premium Tenant has derived and shall derive from such Transfer, and (v) a Transfer relating to this Lease or agreement entered into with respect thereto, whether with or without Landlord’s consent, shall not relieve Tenant from any liability under this Lease, including, without limitation, in connection with the Subject Space. Tenant and Transferee being jointly and severally liable therefor. In the event that Tenant subleases all or any portion of the Premises in accordance with the terms of this Article  14 , Tenant shall cause such subtenant to carry and maintain the same insurance coverage terms and limits as are required of Tenant, in accordance with the terms of Article  10 of this Lease, provided, however, with respect to any sublease of less than 50,000 rentable square feet, the references to “$10,000,000” in Section  10.3.2 shall be deemed to be “$5,000,000”. Landlord or its authorized representatives shall have the right, after ten (10) business days’ prior to Tenant, at all reasonable times to audit the books, records and papers of Tenant relating to the Transfer Premium in connection with a Transfer for which a Transfer Premium is or may be payable, and shall have the right to make copies thereof. If the Transfer Premium respecting any Transfer shall be found understated, Tenant shall, within thirty (30) days after demand, pay the deficiency, and if understated by more than five percent (5%), Tenant shall pay Landlord’s costs of such audit.

14.6 Additional Transfers . For purposes of this Lease, the term “ Transfer ” shall also include (i) if Tenant is a partnership, the withdrawal or change, voluntary, involuntary or by operation of law, of more than fifty percent (50%) or more of the partners, or transfer of more than fifty percent (50%) or more of partnership interests, within a twelve (12)-month period, or the dissolution of the partnership without immediate reconstitution thereof, and (ii) if Tenant is a closely held corporation ( i.e. , whose stock is not publicly held and not traded through an exchange or over the counter), (A) the dissolution, merger, consolidation or other reorganization of Tenant or (B) the sale or other transfer of an aggregate of more than fifty percent (50%) or more of the voting shares of Tenant (other than to immediate family members by reason of gift or death), within a twelve (12)-month period, or (C) the sale, mortgage, hypothecation or pledge of an aggregate of more than fifty percent (50%) or more of the value of the unencumbered assets of Tenant within a twelve (12)-month period.

14.7 Attornment; Default . Each sublease by Tenant hereunder shall be subject and subordinate to this Lease and to the matters to which this Lease is or shall be subordinate, and each subtenant by entering into a sublease is deemed to have agreed that in the event of termination, re-entry or dispossession by Landlord under this Lease, Landlord may, at its option, take over all of the right, title and interest of Tenant, as sublandlord, under such sublease, and such subtenant shall, at Landlord’s option, attorn to Landlord pursuant to the then executory provisions of such sublease, except that Landlord shall not be (i) liable for any previous act or omission of Tenant under such sublease, (ii) subject to any counterclaim, offset or defense that such subtenant might have against Tenant, (iii) bound by any previous modification of such sublease not approved by Landlord in writing or by any rent or additional rent or advance rent which such subtenant might have paid for more than the current month to Tenant, and all such rent shall remain due and owing, notwithstanding such advance payment, (iv) bound by any security or advance rental deposit made by such subtenant which is not delivered or paid over to Landlord and with respect to which such subtenant shall look solely to Tenant for refund or reimbursement, or (v) obligated to perform any work in the subleased space or to prepare it for occupancy, and in connection with such attornment, the subtenant shall execute and deliver to Landlord any instruments Landlord may reasonably request to evidence and confirm such attornment. Each subtenant or licensee of Tenant shall be deemed, automatically upon and as a condition of its occupying or using the Premises or any part thereof, to have agreed to be bound by the terms and conditions set forth in this Section  14.7 . The provisions of this Section  14.7 shall be self-operative, and no further instrument shall be required to give effect to this provision. If Tenant shall be in default under this Lease, Landlord is hereby irrevocably authorized, as Tenant’s agent and attorney-in-fact, to direct any Transferee to make all payments under or in connection with the Transfer directly to Landlord (which Landlord shall apply towards Tenant’s obligations under this Lease) until such default is cured. Such Transferee shall rely on any representation by Landlord that Tenant is in default hereunder, without any need for confirmation thereof by Tenant . Upon any assignment, the assignee shall assume in writing all obligations and covenants of Tenant thereafter to be performed or observed under this Lease. No collection or acceptance of rent by Landlord from any Transferee shall be deemed a waiver of any provision of this Article 14 or the approval of any Transferee or a release of Tenant from any obligation under this Lease, whether theretofore or thereafter accruing. In no event shall Landlord’s enforcement of any provision of this Lease against any Transferee be deemed a waiver of Landlord’s right to enforce any term of this Lease against Tenant or any other person. If Tenant’s obligations hereunder have been guaranteed, Landlord’s consent to any Transfer shall not be effective unless the guarantor also consents to such Transfer.

14.8 Deemed Consent Transfers . Notwithstanding anything to the contrary contained in this Lease, (i) a Transfer to an affiliate of Tenant (an entity which is controlled by, controls, or is under common control with, Tenant), (ii) any transfer of corporate shares of capital stock in Tenant on a nationally-recognized stock exchange, (iii) an assignment of the Lease to an entity which acquires all or substantially all of the stock or assets of Tenant, or (iv) an assignment of the Lease to an entity which is the resulting entity of a merger or consolidation of Tenant during the Lease Term, shall not require Landlord’s consent under this Article 14 or be subject to Section  14.3 above (any such assignee or sublessee described in items (i) through (iv) of this Section  14.8 hereinafter referred to as a “ Permitted Transferee ” and any such Transfer, a “ Permitted Transfer ”), provided that (a) Tenant notifies Landlord at least thirty (30) days prior to the effective date of any such assignment or sublease (unless such notice is legally prohibited or otherwise subject to confidentiality obligations, then Tenant shall notify Landlord as soon as permissible, and in any event within thirty (30) days following the effective date thereof) (such notice from Tenant to Landlord, the “ Permitted Transfer Notice ”) and promptly supplies Landlord with such documents or

information reasonably requested by Landlord to establish that the Transfer qualifies as a Permitted Transfer, (b) Tenant is not in default, beyond the applicable notice and cure period, and such assignment or sublease is not a subterfuge by Tenant to avoid its obligations under this Lease, (c) such Permitted Transferee shall be of a character and reputation consistent with the Class A Standard, (d) any Permitted Transferee Assignee shall have (I) cash or marketable securities of at least $200,000,000 and (II) a tangible net worth (excluding good will and other intangibles) of at least $4,500,000,000, as determined by generally accepted accounting principles, as evidenced by either (A) publically available documentation filed with the SEC that is separate and distinct for the Permitted Transferee (as opposed joint or cumulative filings with an entity that controls the Permitted Transferee or with entities which are otherwise affiliates of the Permitted Transferee), if stock in the entity which constitutes the Permitted Transferee (as opposed to an entity that controls the Permitted Transferee or is otherwise an affiliate of the Permitted Transferee) is publicly traded on NASDAQ or a national stock exchange, or (B) otherwise, a certification that the Permitted Transferee satisfies the Permitted Transferee Credit Requirement, which is factually correct, from a reputable, national, independent CPA firm provided by Tenant as part of the Permitted Transfer Notice, (e) no assignment or sublease relating to this Lease, whether with or without Landlord’s consent, shall relieve Tenant from any liability under this Lease, and (f) the liability of such Permitted Transferee under either an assignment or sublease shall be joint and several with Tenant. An assignee of Tenant’s entire interest in this Lease who qualifies as a Permitted Transferee may also be referred to herein as a “ Permitted Transferee Assignee .” “ Control ,” as used in this Section  14.8 , shall mean the ownership, directly or indirectly, of fifty percent (50%) or more of the voting securities of, or possession of the right to vote, in the ordinary direction of its affairs, of fifty percent (50%) or more of the voting interest in, any person or entity and the ability to direct the affairs of the entity in question.

ARTICLE 15

SURRENDER OF PREMISES; OWNERSHIP AND

REMOVAL OF TRADE FIXTURES

15.1 Surrender of Premises . No act or thing done by Landlord or any agent or employee of Landlord during the Lease Term shall be deemed to constitute an acceptance by Landlord of a surrender of the Premises unless such intent is specifically acknowledged in writing by Landlord. The delivery of keys to the Premises to Landlord or any agent or employee of Landlord shall not constitute a surrender of the Premises or effect a termination of this Lease, whether or not the keys are thereafter retained by Landlord, and notwithstanding such delivery Tenant shall be entitled to the return of such keys at any reasonable time upon request until this Lease shall have been properly terminated. The voluntary or other surrender of this Lease by Tenant, whether accepted by Landlord or not, or a mutual termination hereof, shall not work a merger, and at the option of Landlord shall operate as an assignment to Landlord of all subleases or subtenancies affecting the Premises or terminate any or all such subleases or subtenancies.

15.2 Removal of Tenant Property by Tenant . Upon the expiration of the Lease Term, or upon any earlier termination of this Lease, Tenant shall, subject to the provisions of Section  8.5 above and this Article 15 , quit and surrender possession of the Premises to Landlord in as good order and condition as when Tenant took possession and as thereafter improved by Landlord and/or Tenant, reasonable wear and tear, Casualty and condemnation which is not Tenant’s obligation to repair hereunder, and repairs which are specifically made the responsibility of Landlord hereunder excepted, free of any liens or encumbrances and free of Hazardous Materials placed on the Premises by any Tenant Parties during the Lease Term. Upon such expiration or termination, Tenant shall, without expense to Landlord, remove or cause to be removed from the Premises all debris and rubbish, and such items of furniture, unattached equipment, unattached business and trade fixtures, free-standing cabinet work, movable partitions and walls and other articles of personal property owned by Tenant or installed or placed by any other Tenant Party (but Tenant may not remove any such item which was paid for, in whole or in part, by Landlord unless Landlord requires such removal), and remove such alterations, additions, improvements, and Tenant’s Off-Premises Equipment as Landlord may require pursuant to Section  8.5 above. Tenant shall repair at its own expense all damage to the Premises and Building resulting from removal of the items described above. If Tenant fails upon the expiration or earlier termination of this Lease, subject to any holdover by Tenant pursuant to Article  16 below, to remove any property, including any of the property described above, Landlord may, at Landlord’s option, (i) deem such items to have been abandoned by Tenant, the title thereof shall immediately pass to Landlord at no cost to Landlord, and such items may be appropriated, sold, stored, destroyed, or otherwise disposed of by Landlord without notice to Tenant and without any obligation to account for such items; any such disposition shall not be

considered a strict foreclosure or other exercise of Landlord’s rights in respect of the security interest granted hereunder or otherwise, (ii) remove such items, perform any work required to be performed by Tenant hereunder, and repair all damage caused by such work, and Tenant shall reimburse Landlord on demand for any expenses which Landlord may incur in effecting compliance with Tenant’s obligations hereunder (including collection costs and attorneys’ fees), plus interest thereon at the Interest Rate, or (iii) elect any of the actions described in clauses (i) and (ii) above as Landlord may elect in its sole discretion. The provisions of this Article 15 shall survive the end of the Lease Term.

ARTICLE 16

HOLDING OVER

If Tenant holds over after the expiration of the Lease Term, with the express written consent of Landlord, such tenancy shall be from month-to-month only, and shall not constitute a renewal hereof or an extension for any further term, and in such case Base Rent shall be payable at a monthly rate of one hundred ten percent (110%) of the Base Rent applicable during the last rental period of the Lease Term under this Lease. Such month-to-month tenancy shall be subject to every other applicable term, covenant and agreement contained herein. If Tenant holds over after the expiration of the Lease Term without the express written consent of Landlord, such tenancy shall be a tenancy at sufferance, and shall not constitute a renewal hereof or an extension for any further term, and in such case daily damages in any action to recover possession of the Premises shall be calculated at a daily rate equal to one hundred twenty-five percent (125%) of the Base Rent applicable during the last rental period of the Lease Term under this Lease (calculated on a per diem basis) for the first six (6) months of such holdover and one hundred fifty percent (150%) of the Base Rent applicable during the last Lease Month of the Lease Term (calculated on a per diem basis) thereafter. Nothing contained in this Article  16 shall be construed as consent by Landlord to any holding over by Tenant, and Landlord expressly reserves the right to require Tenant to vacate and deliver possession of the Premises to Landlord as provided in this Lease upon the expiration or other termination of this Lease. The provisions of this Article  16 shall not be deemed to limit or constitute a waiver of any other rights or remedies of Landlord provided herein or at law. If Tenant holds over without Landlord’s express written consent, and tenders payment of rent for any period beyond the expiration of the Lease Term by way of check (whether directly to Landlord, its agents, or to a lock box) or wire transfer, Tenant acknowledges and agrees that the cashing of such check or acceptance of such wire shall be considered inadvertent and not be construed as creating a month-to-month tenancy, provided Landlord refunds such payment to Tenant promptly upon learning that such check has been cashed or wire transfer received. Tenant acknowledges that any holding over without Landlord’s express written consent may compromise or otherwise affect Landlord’s ability to enter into new leases with prospective tenants regarding the Premises. Therefore, if Tenant fails to vacate and deliver the Premises within sixty (60) days following the termination or expiration of this Lease, and Landlord has not consented in writing to such holdover, in addition to any other liabilities to Landlord accruing therefrom, Tenant shall protect, defend, indemnify and hold Landlord harmless from and against all claims made by any succeeding tenant founded upon such failure to vacate and deliver, and any losses suffered by Landlord, including lost profits and damages, resulting from such failure to vacate and deliver. Tenant agrees that any proceedings necessary to recover possession of the Premises, whether before or after expiration of the Lease Term, shall be considered an action to enforce the terms of this Lease for purposes of the awarding of any attorney’s fees in connection therewith.

ARTICLE 17

ESTOPPEL CERTIFICATES

Subject to Section  19.1.3 below, within ten (10) business days following a request in writing by Landlord, Tenant shall execute, acknowledge and deliver to Landlord an estoppel certificate, which, as submitted by Landlord, shall be substantially in the form of Exhibit  E , attached hereto (or such other form as may be required by any prospective mortgagee or purchaser of the Project, or any portion thereof), indicating therein any exceptions thereto that may exist at that time, and shall also contain any other information reasonably requested by Landlord or Landlord’s mortgagee or prospective mortgagee. Any such certificate may be relied upon by any prospective mortgagee or purchaser of all or any portion of the Project. At any time during the Lease Term, but only in connection with a sale, financing or refinancing of the Project, or any portion or interest therein, Landlord may require Tenant to provide Landlord with a current financial statement and financial statements of the two (2) years

prior to the current financial statement year. Such statements shall be prepared in accordance with generally accepted accounting principles and, if such is the normal practice of Tenant, shall be audited by an independent certified public accountant. In no event shall Tenant be obligated to deliver to Landlord the same financial statements more than one time. Further, notwithstanding anything contained herein to the contrary, Tenant shall have no obligation to deliver financial statements hereunder in the event that Tenant is a publicly traded corporation. Failure of Tenant to timely execute, acknowledge and deliver an estoppel certificate as required under this Article  17 shall constitute an acceptance of the Premises and an acknowledgment by Tenant that statements included in the estoppel certificate are true and correct, without exception.

Landlord shall, at any time and from time to time (but no more often than one (1) time in any twelve-month period) within ten (10) business days after written request therefor by Tenant, without charge, deliver to Tenant or to any person or entity designated by Tenant, a certificate from Landlord certifying the date the Lease Term commenced, the date the Rent commenced and is paid through, the amount of Rent and other charges due under this Lease, the Lease Expiration Date (and any then-remaining rights to extend the Lease Term), that this Lease is then in full force and effect, and any other factual matter concerning this Lease, Landlord, the Premises or the Project reasonably requested by Tenant or such person or entity (limited to Landlord’s actual knowledge, where Landlord reasonably determines such limitation to be appropriate).

ARTICLE 18

SUBORDINATION

This Lease shall be subject and subordinate to all present and future ground or underlying leases of the Building or Project and to the lien of any mortgage, trust deed or other encumbrances now or hereafter in force against the Building or Project or any part thereof, if any, and to all renewals, extensions, modifications, consolidations and replacements thereof, and to all advances made or hereafter to be made upon the security of such mortgages or trust deeds (collectively, “ Mortgages ”), unless the holders of such mortgages, trust deeds or other encumbrances, or the lessors under such ground lease or underlying leases (collectively, “ Mortgage Holders ”), require in writing that this Lease be superior thereto. Tenant covenants and agrees in the event any proceedings are brought for the foreclosure of any such mortgage or deed in lieu thereof (or if any ground lease is terminated), to attorn, without any deductions or set-offs whatsoever, to the Mortgage Holder or any successors thereto upon any such foreclosure sale or deed in lieu thereof, if so requested to do so by such Mortgage Holder, and to recognize such Mortgage Holder as the lessor under this Lease, provided such Mortgage Holder shall agree recognize this Lease in the event of any foreclosure, sale under power of sale, or transfer in lieu of the foregoing and to accept this Lease and not disturb Tenant’s occupancy, use and enjoyment of the Premises, so long as Tenant timely pays the rent and is not in default under this Lease after the expiration of any applicable notice and cure period. Notwithstanding the foregoing, the subordination of this Lease to any future Mortgage shall be subject to, and conditioned upon, Tenant’s receipt of a commercially reasonable non-disturbance agreement (a “ SNDA ”) in recordable form which provides in substance that so long as Tenant is not in default under this Lease past applicable cure periods, its use and occupancy of the Premises shall not be disturbed, notwithstanding any default of Landlord under such Mortgage. It shall not be reasonable for Tenant to disapprove an SNDA if it is at least as favorable in all material respects to Tenant as the form of SNDA attached hereto as Exhibit  G . Landlord’s interest herein may be assigned as security at any time to any Mortgage Holder. Subject to Section  19.1.3 below, Tenant shall, within ten (10) business days of request by Landlord, execute such further instruments or assurances as Landlord may reasonably deem necessary to evidence or confirm the subordination or superiority of this Lease to any such Mortgages. Tenant waives the provisions of any current or future statute, rule or law which may give or purport to give Tenant any right or election to terminate or otherwise adversely affect this Lease and the obligations of the Tenant hereunder in the event of any foreclosure proceeding or sale. Concurrently with execution of this Lease, Landlord shall provide Tenant with an SNDA from Landlord’s current lender for the Project in the form of Exhibit G attached hereto.

ARTICLE 19

DEFAULTS; REMEDIES

19.1 Events of Default . The occurrence of any of the following shall constitute a default of this Lease by Tenant:

19.1.1 Any failure by Tenant to pay any Rent or any other charge required to be paid under this Lease, or any part thereof, when due unless such failure is cured within five (5) business days after notice from Landlord of Tenant’s failure to pay; or

19.1.2 Except where a specific time period is otherwise set forth for Tenant’s performance in this Lease, in which event the failure to perform by Tenant within such time period shall be a default by Tenant under this Section  19.1.2 , any failure by Tenant to observe or perform any other provision, covenant or condition of this Lease to be observed or performed by Tenant where such failure continues for thirty (30) days after written notice thereof from Landlord to Tenant; provided that if the nature of such default is such that the same cannot reasonably be cured within a thirty (30) day period, Tenant shall not be deemed to be in default if it diligently commences such cure within such period and thereafter diligently proceeds to rectify and cure such default; or

19.1.3 The failure by Tenant to observe or perform according to the provisions of Articles  17  or  18 of this Lease where such failure continues for more than five (5) business days after notice from Landlord, which notice, for the avoidance of doubt, shall be in addition to Landlord’s initial request made under Article 17 or 18 .

The notice periods provided herein are in lieu of, and not in addition to, any notice periods provided by law.

19.2 Remedies Upon Default . Upon the occurrence of any event of default by Tenant (following expiration of the applicable notice and cure period), Landlord shall have, in addition to any other remedies available to Landlord at law or in equity (all of which remedies shall be distinct, separate and cumulative), the option to pursue any one or more of the following remedies, each and all of which shall be cumulative and nonexclusive, without any notice or demand whatsoever.

19.2.1 Terminate this Lease, in which event Tenant shall immediately surrender the Premises to Landlord, and if Tenant fails to do so, Landlord may, without prejudice to any other remedy which it may have for possession or arrearages in rent, enter upon and take possession of the Premises and expel or remove Tenant and any other person who may be occupying the Premises or any part thereof, without being liable for prosecution or any claim for damages therefor; and Landlord may recover from Tenant the following:

19.2.1.1 The worth at the time of award of any unpaid rent which has been earned at the time of such termination; plus

19.2.1.2 The worth at the time of award of the amount by which the unpaid rent which would have been earned after termination until the time of award exceeds the amount of such rental loss that Tenant proves could have been reasonably avoided; plus

19.2.1.3 The worth at the time of award of the amount by which the unpaid rent for the balance of the Lease Term after the time of award exceeds the amount of such rental loss that Tenant proves could have been reasonably avoided; plus

19.2.1.4 Any other amount necessary to compensate Landlord for all the detriment proximately caused by Tenant’s failure to perform its obligations under this Lease or which in the ordinary course of things would be likely to result therefrom, specifically including but not limited to, brokerage commissions and advertising expenses incurred, expenses of remodeling the Premises or any portion thereof for a new tenant, whether for the same or a different use, and any special concessions made to obtain a new tenant; and

19.2.1.5 At Landlord’s election, such other amounts in addition to or in lieu of the foregoing as may be permitted from time to time by applicable law.

The term “ rent ” as used in this Section  19.2 shall be deemed to be and to mean all sums of every nature required to be paid by Tenant pursuant to the terms of this Lease, whether to Landlord or to others. As used in Sections  19.2.1.1  and  19.2.1.2 , above, the “worth at the time of award” shall be computed by allowing interest at the Interest Rate. As used in Section  19.2.1.3 , above, the “worth at the time of award” shall be computed by discounting such amount at the discount rate of the Federal Reserve Bank of San Francisco at the time of award plus one percent (1%).

19.2.2 If Landlord does not elect to terminate this Lease on account of any default by Tenant, Landlord may continue the Lease in effect (whether or not Tenant has abandoned or vacated the Premises) and, from time to time, without terminating this Lease, enforce all of its rights and remedies under this Lease, including the right to recover all rent as it becomes due.

19.2.3 Landlord may re-enter and attempt to relet the Premises without terminating this Lease and remove all persons and property from the Premises (which property may be removed and stored in a public warehouse or elsewhere at the sole cost and risk of, and for the account of, Tenant), all without service of notice or resort to legal process and without being deemed guilty of trespass, or any liability of Landlord for any loss or damage which may be occasioned thereby. If Landlord, without terminating this Lease, either (i) elects to re-enter the Premises and attempts to relet the Premises, (ii) takes possession of the Premises pursuant to legal proceedings, or (iii) takes possession of the Premises pursuant to any notice provided by law, then Landlord may, from time to time, make such alterations and repairs as may be necessary in order to relet the Premises or any part thereof for such term or terms (which may be for a term extending beyond the Lease Term) and at such rent and other terms as Landlord in its reasonable discretion deems advisable; provided, however, Landlord shall use commercially reasonable efforts to mitigate damages in the event Landlord pursues its remedies under this sentence. Upon such reletting, all rent received by Landlord from such reletting shall be applied, first to the payment of any indebtedness of Tenant to Landlord (other than for any rent due hereunder); second, to the payment of any costs and expenses of obtaining possession and any such reletting, including the expense of alterations and repairs, brokerage fees and attorneys’ fees; third, to the payment of any rent due and unpaid hereunder. If such rents and any other amounts received from such reletting during any month are less than that to be paid during that month by Tenant, then Tenant shall immediately pay such deficiency to Landlord. No such re-entry or taking of possession of the Premises by Landlord shall be construed as an election by Landlord to terminate this Lease unless a notice of such intention is given by Landlord to Tenant. Notwithstanding any such reletting without termination, Landlord may at any time thereafter elect to terminate this Lease for such previous default. Should Landlord at any time terminate this Lease for any default, in addition to any other remedies it may have, Landlord shall be entitled to the remedy set forth in Section  19.2.1 above, and may recover all damages it may incur by reason of such default, including the cost of recovering the Premises, reimbursement of any brokerage fees incurred by Landlord in connection with this Lease and all rent (accrued or to accrue during the Lease Term) which, at Landlord’s election, shall be accelerated and be due in full on demand.

19.2.4 Landlord shall at all times have the rights and remedies set forth in this Section  19.2 (which shall be cumulative with each other), without prior demand or notice except as required by applicable law, to seek any declaratory, injunctive or other equitable relief, and specifically enforce this Lease, or restrain or enjoin a violation or breach of any provision hereof.

19.3 Subleases of Tenant . Whether or not Landlord elects to terminate this Lease on account of any default by Tenant, as set forth in this Article  19 , Landlord shall have the right to terminate any and all subleases, licenses, concessions or other consensual arrangements for possession entered into by Tenant and affecting the Premises or may, in Landlord’s sole discretion, succeed to Tenant’s interest in such subleases, licenses, concessions or arrangements. In the event of Landlord’s election to succeed to Tenant’s interest in any such subleases, licenses, concessions or arrangements, Tenant shall, as of the date of notice by Landlord of such election, have no further right to or interest in the rent or other consideration receivable thereunder.

19.4 Efforts to Relet . No re-entry or repossession, repairs, maintenance, changes, alterations and additions, reletting, appointment of a receiver to protect Landlord’s interests hereunder, or any other action or

omission by Landlord shall be construed as an election by Landlord to terminate this Lease or Tenant’s right to possession, or to accept a surrender of the Premises, nor shall same operate to release Tenant in whole or in part from any of Tenant’s obligations hereunder, unless express written notice of such intention is sent by Landlord to Tenant. Tenant hereby irrevocably waives any right otherwise available under any law to redeem or reinstate this Lease.

19.5 Landlord Default . Notwithstanding anything to the contrary set forth in this Lease, Landlord shall be in default in the performance of any obligation required to be performed by Landlord pursuant to this Lease if Landlord fails to perform such obligation within thirty (30) days after the receipt of notice from Tenant specifying in detail Landlord’s failure to perform; provided, however, if the nature of Landlord’s obligation is such that more than thirty (30) days are required for its performance, then Landlord shall not be in default under this Lease if it shall commence such performance within such thirty (30) day period and thereafter diligently pursues the same to completion. Upon any such default by Landlord under this Lease, Tenant may, except as otherwise specifically provided in this Lease to the contrary, exercise any of its rights provided at law or in equity. Any award from a court or arbitrator in favor of Tenant requiring payment by Landlord which is not paid by Landlord within the time period directed by such award, may be offset by Tenant from Rent next due and payable under this Lease; provided, however, Tenant may not deduct the amount of the award against more than fifty percent (50%) of Base Rent next due and owing (until such time as the entire amount of such judgment is deducted) to the extent following a foreclosure or a deed-in-lieu of foreclosure.

ARTICLE 20

COVENANT OF QUIET ENJOYMENT

Landlord makes no representations or warranties whatsoever with respect to the condition of the roof of the Building, or the fitness or suitability of the roof of the Building for the installation, maintenance and operation of the Rooftop Equipment, including, without limitation, with respect to the quality and clarity of any receptions and transmissions to or from the Rooftop Equipment and the presence of any interference with such signals whether emanating from the Building or otherwise. For all purposes under this Lease, the Rooftop Equipment shall be deemed to be included within the definition of Tenant’s Off-Premises Equipment. Tenant’s obligations under this Article  21 are cumulative and in addition to all other obligations of Tenant under this Lease.

21.2 Installation of Rooftop Equipment . In the event Tenant elects to exercise its right to install the Rooftop Equipment, then Tenant shall give Landlord prior written notice thereof and shall submit to Landlord (a) construction ready plans and specifications (specifically including, without limitation, all mounting and waterproofing details) prepared by a registered professional engineer in the State in which the Premises are located and reasonably approved by Landlord which (i) specify in detail the design, location, size, model, weight, method of installation and method of screening and frequency of the Rooftop Equipment and (ii) are sufficiently detailed to allow for the installation of the Rooftop Equipment in a good and workmanlike manner and in accordance with all Applicable Laws for Landlord’s review and approval (such submission, review and approval shall be governed by

Article 8 of the Lease, the Tenant Work Letter (if the Rooftop Equipment is being constructed by Tenant as part of the Tenant Improvements) and this Article  21 ); provided, however, that Landlord may withhold consent in its sole and absolute discretion if the weight of the Rooftop Equipment would require the installation of bracing or other structural support or would affect Landlord’s roof warranties and (b) all necessary consents, approvals, permits or registrations, including architectural guidelines in effect for the area in which the Building is located as they may be amended from time to time, required for the installation, maintenance, use or operation of the Rooftop Equipment in accordance with Applicable Law.

Tenant shall remain solely liable for any damage arising in connection with Tenant’s installation, use, maintenance and/or repair of such Rooftop Equipment, including, without limitation, any damage to a portion of the roof or roof membrane and any penetrations to the roof. Landlord may require, as a condition to Landlord’s approval of the plans and specifications, Tenant to install screening around such Rooftop Equipment, at Tenant’s sole cost and expense, as reasonably designated by Landlord. Tenant shall reimburse to Landlord the actual costs reasonably incurred by Landlord in approving such Rooftop Equipment. If the Rooftop Equipment uses any electricity, Tenant shall pay for the cost to purchase and install electrical submeter equipment and wiring, and thereafter Tenant shall pay to Landlord the monthly electrical submeter charges throughout the Term. Landlord’s approval of any such plans and specifications shall not constitute a representation or warranty by Landlord that such plans and specifications comply with sound architectural guidelines and/or engineering practices or will comply with all Applicable Laws; such compliance shall be the sole responsibility of Tenant. Tenant shall maintain all permits necessary for the maintenance and operation of the Rooftop Equipment while it is on the Building, and all such permits shall be in Tenant’s name.

If Landlord so requires, Tenant, at Tenant’s sole cost and expense, shall retain any contractor having a then-existing warranty in effect on the roof to perform such work (to the extent that it involves the roof), or, at Tenant’s option, to perform such work in conjunction with Tenant’s contractor.

21.3.2 If Landlord contemplates roof repairs or other work on the roof that could affect the Rooftop Equipment or could result in an interruption of service from the Rooftop Equipment, Landlord shall give Tenant not less than thirty (30) days prior notice (or, in an emergency, such other notice as may be practicable under the circumstances). Landlord shall use commercially reasonable efforts to avoid or minimize any interference with Tenant’s use of the Rooftop Equipment and any interruption in the service provided by the Rooftop Equipment.

Tenant shall remain solely liable for any damage arising in connection with Tenant’s installation, use, maintenance and/or repair of such Rooftop Equipment, including, without limitation, any damage to a portion of the roof or roof membrane and any penetrations to the roof. Prior to the expiration of this Lease or, if earlier, within five days after this Lease or Tenant’s right to possess the Premises has been terminated or Tenant’s vacating the Premises or the termination of Tenant’s rights under this Article  21 , Tenant shall, at its sole risk and expense, remove the Rooftop Equipment, repair any damage caused thereby and restore the affected portion of the rooftop, the Building and the Premises to the condition the rooftop, the Building and the Premises would have been in had no such Rooftop Equipment been installed (reasonable wear and tear and damage from Casualty and condemnation that is not Tenant’s obligation to repair pursuant to Article 11 , above excepted). If Tenant fails to do so, Landlord may remove the Rooftop Equipment and store or dispose of it in any manner Landlord deems appropriate without liability to Tenant; Tenant shall reimburse Landlord for all actual and substantiated costs incurred by Landlord in connection therewith, plus Landlord’s standard administrative fee, within ten days after Landlord’s request therefor.

21.4 Use of Rooftop Equipment . Tenant shall not be entitled to license its Rooftop Equipment to any third party (as opposed to Transferees (including Permitted Transferees)), nor shall Tenant be permitted to receive any revenues, fees or any other consideration for the use of such Rooftop Equipment by a third party. Tenant’s right to install such Rooftop Equipment shall be non-exclusive, and Tenant hereby expressly acknowledges Landlord’s continued right to itself utilize a portion of the rooftop of the Building, to grant similar rights to other tenants, subtenants, and occupants of the Project (if any), and to grant rights to other third parties.

21.5 No Interference . Landlord shall not and shall not permit any other person to install equipment on or to make alterations or improvements to the roof of the Building of a type or in a location that will cause radio frequency or electromagnetic interference with any Rooftop Equipment that Landlord has already approved and Tenant has already installed (the “ Interference-Protected Rooftop Equipment ”). If Landlord installs or permits any other person to install equipment on or to make alterations or improvements to the roof of the Building that cause radio frequency or electromagnetic interference with any Interference-Protected Rooftop Equipment, Landlord shall take all steps necessary to stop the use of such other equipment and to remove or modify such alterations or improvements so that such interference ceases.

21.5.2 If Landlord, Tenant or any other person changes the operation of its rooftop equipment installed in compliance with this Section  21.5 (i.e., without causing radio frequency or electromagnetic interference with other rooftop equipment) and such change in operation creates radio frequency or electromagnetic interference with other rooftop equipment, the provisions of Sections 21.2 above shall apply as if such change in operation constituted the installation of new rooftop equipment.

21.5.3 If Landlord contemplates roof repairs or other work on the roof that could affect the Rooftop Equipment or could result in an interruption of service from the Rooftop Equipment, Landlord shall give Tenant not less than thirty (30) days prior notice (or, in an emergency, such other notice as may be practicable under the circumstances).

The graphics, materials, color, design, lettering, lighting, size, illumination, specifications and exact location of Tenant’s Signage shall be subject to the prior written approval of Landlord, which approval shall not be unreasonably withheld, conditioned or delayed; provided, however, without limiting other reasons for which Landlord may reasonably withhold its approval, it shall be deemed reasonable for Landlord to withhold its approval of Tenant’s Signage if the same is inconsistent with, or otherwise not compatible with the Class A Standard.

In connection with the foregoing, any new name or logo on Tenant’s Signage shall not be an Objectionable Name.

23.4.4 Cost and Maintenance . If Landlord grants its approval, Tenant shall erect Tenant’s Signage in accordance with the approved plans and specifications, in a good and workmanlike manner, in accordance with all Applicable Laws, so long as Tenant has received all requisite approvals thereunder (the “ Sign Requirements ”), and in a manner so as not to unreasonably interfere with the use of the Project grounds while such construction is taking place; thereafter, Tenant shall maintain Tenant’s Signage in a good, clean and safe condition in accordance with the Sign Requirements, all at Tenant’s sole cost and expense. Subject to the TCCs of this Article 23 , including the process for Landlord’s review and approval of Tenant’s Signage, Tenant’s Signage shall be constructed pursuant to the TCCs of Article 8 above, if an Alteration, or pursuant to the TCCs of the Tenant Work Letter, if a Tenant Improvement.

The TCCs of this Section  23.4 shall survive the expiration or earlier termination of this Lease.

Pursuant to the Name/Identity Right, Landlord shall rename the Building to the name F5 Tower (the “ Building Name ”). Landlord will not disapprove any Building Name containing a designation that also contains the name of the Original Tenant or any Permitted Transferee Assignee. Notwithstanding the foregoing, the Building Name shall not be substantially similar to the name of any other office project in the Seattle/Bellevue area, or contain any Objectionable Name.

ARTICLE 28

TENANT PARKING

28.1 The Parking Garage . Landlord shall construct the Parking Garage in accordance with the Base Building Plans, and street access to the Parking Garage shall be materially consistent with Exhibit  A-3 attached hereto. Subject to Applicable Laws, Articles 11 and 13 , and Sections  1.1.4 and 29.30 of this Lease, and temporary closures contemplated in Section  28.5 below, at all times during the Lease Term (i) the Parking Garage shall include at least two hundred fifty-nine (259) parking stalls (the “ Building Spaces ”) and (ii) parking for at least eighty-four (84) bicycles and associated shower facilities (the “ Bicycle Facilities ”). Tenant acknowledges that an additional sixty-two (62) parking stalls (the “ TRC Spaces ”, together with the Building Spaces, the “ Spaces ”, and each a “ Space ”) in the Parking Garage belong to The Rainier Club (the “ Rainier Club ”), and that, as of the date hereof, Landlord is leasing the TRC Spaces from the Rainier Club (the “ TRC Parking Lease ”). At any time that the TRC Parking Lease is in effect (i.e., including the TRC Spaces), subject to Applicable Laws, Articles 11 and 13, and Sections  1.1.4 and 29.30 of this Lease, and temporary closures contemplated in Section  28.5 below, the Parking Garage shall include at least three hundred twenty-one (321) parking stalls, which shall include the number of compact Spaces and handicap Spaces required by Applicable Laws. After the Lease Commencement Date, Landlord shall not re-stripe the Parking Garage to materially increase the number of compact Spaces, except as required by Applicable Law, without Tenant’s reasonable consent.

28.2 Rainier Club Parking; Rainier Club Lease . Tenant acknowledges and agrees that, pursuant to the TRC Parking Lease, the Rainier Club and its visitors have certain rights to use the TRC Spaces from time to time (the “ Rainier Club Use ”). Landlord shall use commercially reasonable efforts to provide Tenant with prior notice of any Rainier Club Use, which use is in connection with a weekday event at the Rainier Club, which notice may be provided via email to an address or addresses designated by Tenant, or by posting notices at the Building. If reasonably required to accommodate the Rainier Club Use of the Parking Garage, Landlord shall have the right to institute off-site, or valet assisted parking, or to permit transient parking to accommodate the Rainier Club Use; provided, however, (i) Landlord shall use commercially reasonable efforts to minimize the number of Tenant’s Parking Passes affected by any such off-site or valet assisted parking (and any off-site parking for any of Tenant’s Parking Passes shall require Tenant’s prior written consent) in connection with the Rainier Club Use, and (ii) if any of holders of any of Tenant’s Parking Passes (each, a “ Holder ”) are reasonably unable to find a Space in the Parking Garage (other than on Nights and Weekends (defined below)) due to the Rainier Club Use, and such Holder enters the Parking Garage to find a Space and then exits the Parking Garage and then parks outside of the Parking Garage, Landlord shall reimburse Tenant for the actual costs incurred by such Holder to find alternative parking within the general vicinity of the Project for that day, within thirty (30) days of receipt of an invoice therefor (not to exceed a total of sixty-two (62) Parking Passes on any particular day) (the “ Reimbursement Right ”). If Tenant exercises its Reimbursement Right, it shall be assumed that such exercise was due to the Rainier Club Use; provided, however, by written notice to Tenant, Landlord shall have the right to object to the determination of any Holder that Spaces were not available, and that such lack of availability was due to the Rainier Club Use. Landlord shall have the burden of proof of unavailability due to Rainier Club Use (as opposed to use of the Parking Garage by Tenant and its visitors). In connection with such objection, the parties shall meet within ten (10) business days after Tenant’s receipt of Landlord’s notice at a commercially reasonable, mutually agreed upon time and attempt to resolve any such objections. In addition, if Tenant is requesting reimbursement from Landlord pursuant to the Reimbursement Right more frequently than twice per month, upon request from Tenant, Landlord shall meet with Tenant at a commercially reasonable, mutually agreed upon time during the ten (10) business day period to discuss the foregoing and solutions to minimize the effect of the Rainier Club Use on Holders of Tenant’s Parking Passes. Landlord will use commercially reasonable efforts (not including the incurrence of material costs by Landlord, including, without limitation, payment of any fee or other consideration to the Rainier Club for such extension, other than the reasonable legal and administrative costs of negotiating such extension) to extend the term of the TRC Parking Lease through the expiration of this Lease, on terms which are acceptable to Landlord in its sole discretion.

Upon request from Tenant, Landlord shall use commercially reasonable efforts to enforce any of Landlord’s rights under the TRC Parking Lease and/or the Underlying Documents in order to cause the Rainier Club to comply with the Rainier Club’s obligations thereunder, to the extent such enforcement is required for Landlord to comply with this Lease. Notwithstanding the foregoing, neither Tenant nor any other Tenant Parties shall contact, discuss with, or negotiate with, any board member, employee or other members of the Rainier Club regarding the TRC Parking Lease or the terms thereof, as the same may be amended.

28.3 Parking Passes .

28.3.1 Subject to Section  28.2.3 below, and to the Rainier Club Use, Tenant shall rent from Landlord (i) three hundred twenty-one (321) parking passes if the TRC Parking Lease is in effect, and, otherwise two hundred fifty-nine (259) parking passes (such passes, in each instance, the “ Tenant’s Unfloated Passes ”) and (ii) thirty-nine (39) additional parking passes, based on a fifteen percent (15%) float (the “ Float ”) on the Building Spaces, which float may be increased by Landlord to twenty percent (20%) upon Tenant’s consent, not to be unreasonably withheld. Tenant may increase the number of additional parking passes rented by Tenant, upon thirty (30) days prior written notice to Landlord, subject to Applicable Laws (and in no event shall the total Float, as modified, exceed fifty percent (50%) of the Building Spaces), and all such additional passes above Tenant’s Unfloated Passes, actually rented by Tenant are the “ Tenant’s Floated Passes ”. Tenant’s Unfloated Passes and Tenant’s Floated Passes are collectively the “ Parking Passes ”. Each Parking Pass rented by Tenant pursuant to this Section  28.3.1 shall provide the Holder with the right to use the Parking Garage at all times, provided that any use of the Parking Garage on Nights and Weekends (defined below) shall be on a first-come, first-serve basis. Notwithstanding the foregoing, in the event that Spaces are unreasonably unavailable in the Parking Garage on Nights and Weekends due to the exercise of Landlord’s rights set forth in Section  28.4 below, in Tenant’s reasonable discretion, upon at least thirty (30) days prior written notice to Landlord, Tenant may direct Landlord to label or otherwise restrict up to fifty (50) Spaces on Level J of the Parking Garage (or such other location as reasonably determined by Landlord) as exclusively designated for use by Holders during Nights and Weekends and Tenant shall use commercially reasonable efforts to cause any Holders first entering the Parking Garage on Nights and Weekends to first park in such designated Spaces (“ Tenant’s After-Hours Requirement ”). Tenant shall have the right to increase the number of Spaces pertaining to Tenant’s After-Hours Requirement by up to five (5) Spaces per Lease Year commencing on the first anniversary of the Lease Commencement Date, on a cumulative and compounding basis, but the total of such Spaces shall not exceed one hundred twenty (120) Spaces. In addition, upon at least thirty (30) days prior written notice to Landlord, in Tenant’s sole discretion, Tenant may direct Landlord to label or otherwise restrict up to twenty-three (23) Building Spaces on Level C as exclusively reserved for use by Tenant’s visitors, other than on Nights and Weekends (“ Tenant’s Visitor Requirement ”). Other than on Nights and Weekends, Landlord shall, or shall cause, signs to be placed at the entrance(s) of the Parking Garage stating “No Public Parking; Parking Reserved for F5 Networks and Guests Only”. Tenant expressly acknowledges and agrees that Tenant’s Visitor Requirement and any electrical vehicle parking contemplated by Section  28.6 below, due to the fact that such Spaces are not subject to a “float” factor, may adversely affect the availability of Spaces to Holders and Landlord shall have no liability in connection with such availability.

28.3.2 Costs of Parking Passes . Tenant shall pay to Landlord (or its designee) for the Parking Passes rented by Tenant on a monthly basis at the prevailing rate charged from time to time for the Parking Garage (together with any taxes imposed by any governmental authority in connection with the renting of the Parking Passes by Tenant or the use of the Parking Garage by Tenant), which rates shall be materially consistent with the rates then being charged at Comparable Buildings with garages underneath such buildings (as opposed to surface lots or adjacent garages) and the types of passes, as reasonably designated by Landlord, rented by Tenant (the “ Prevailing Rate ”).

28.3.3 Use of Parking Passes . Tenant’s continued right to use the Parking Passes is conditioned upon Tenant abiding by all rules and regulations which set forth in the parking manual to be developed by Landlord (the “ Parking Manual ”) for the orderly operation and use of the Parking Garage, including any sticker or other identification system established by Landlord, Tenant’s cooperation in seeing that Tenant’s Holders and visitors also comply with such rules and regulations set forth in the Parking Manual. Prior to finalizing or amending the rules and regulations set forth in the Parking Manual (the “ Parking Manual Modifications ”) (excluding any rules and regulations (i) required by Applicable Laws, (ii) otherwise required in accordance with the TCCs of this Lease, or (iii) reasonably necessary to address an emergency circumstance or Casualty), (a) Landlord shall provide ten (10)    

business days’ advance written notice to Tenant identifying, in reasonable detail, the proposed rule and regulation (or modification thereto) and the reason for the same, (b) Landlord shall at Tenant’s election, meet with Tenant at a commercially reasonable, mutually agreed upon time during the ten (10) business day period before the commencement of the effectiveness of the rule and regulation (or modification thereto) to discuss the same, (c) consider in good faith any reasonable objections of Tenant to the rule and regulation (or modification thereto) by Tenant, whether such objection is made in writing during such ten (10) business day period or at the aforementioned meeting. In addition, except as may be required by items (i) through (iii) above, Landlord shall not implement any Parking Manual Modifications that would materially and adversely affect Tenant’s rights and Landlord’s obligations under this Article 28, without first obtaining Tenant’s prior written consent, which consent shall not be unreasonably withheld, conditioned or delayed, and shall be granted or withheld within ten (10) business days of Landlord’s request. Any Parking Manual Modifications entered into without Tenant’s consent, in violation of the foregoing sentence, shall not be binding on Tenant. The Parking Passes are provided to Tenant solely for use by Tenant’s own personnel and may not be transferred, assigned, subleased or otherwise alienated by Tenant without Landlord’s prior approval, except on a pro-rata basis in connection with a Transfer to which Landlord has consented or for which Landlord’s consent is not required.

28.4 Nights and Weekends . Notwithstanding Tenant’s rights set forth in Section  28.3 above, but subject to Tenant’s After-Hours Requirement, if applicable, Landlord shall have the right to sell transient parking passes for parking in the Spaces in the Parking Garage between the hours of 4:30 p.m. to 6:00 a.m. Monday through Friday, and on weekends from the hours of 12:01 a.m. on Saturday to 5:59 a.m. on Monday (collectively, “ Nights and Weekends ”). For the avoidance of doubt, Landlord shall not have the right to sell transient parking for Spaces in the Parking Garage during Tenant Parking Hours to any party including, but not limited to, the Rainier Club (other than in connection with the Rainier Club Use).

28.5 Operation of the Parking Garage . Subject to Landlord’s Obligations to Minimize Tenant Interference and the terms of Section  1.1.4 above and this Article  28 , Landlord specifically reserves the right to change the size (but not decrease the size), configuration, design, layout and all other aspects of the Parking Garage (including the Bicycle Facilities) at any time. Tenant acknowledges and agrees that Landlord may, without incurring any liability to Tenant and without any abatement of Rent under this Lease, from time to time, temporarily close-off or restrict access to the Parking Garage and/or Bicycle Facilities for purposes of permitting or facilitating any such construction, alteration or improvements, subject to Landlord’s Obligations to Minimize Tenant Interference and the terms of Section  1.1.4 above and this Article  28 , and provided that Landlord makes reasonably comparable parking available during any closures of the Parking Garage. Landlord may delegate its responsibilities hereunder to a parking operator in which case such parking operator shall have all the rights of control attributed hereby to the Landlord; provided that any such parking operator shall have experience operating parking garages in Comparable Buildings or comparable parking garages.

28.6 Electrical Vehicle Charging Stations . Upon request from Tenant, Landlord shall cooperate with Tenant to identify locations to install, at Landlord’s sole cost and expense, conduit for up to ten (10) electrical vehicle charging stations in the Parking Garage; provided that Tenant shall otherwise be solely responsible, at Tenant’s sole cost and expense (or as a deduction from the Tenant Improvement Allowance), for installation of any electrical vehicle charging stations. In the event Tenant elects to install any such electrical vehicle charging stations, the same shall be designated for exclusive use by Tenant, except as required by Applicable Laws, and Tenant shall at all times rent Parking Passes pertaining to the number of electrical vehicle charging stations, at the Prevailing Rate applicable to the other Parking Passes.

28.7 Parking Garage Lease . Prior to the Lease Commencement Date, the parties shall use commercially reasonable efforts to enter into a lease or license agreement pertaining to Tenant’s use of the Parking Garage (the “ Parking Garage Lease ”). The TCCs of the Parking Garage Lease shall be substantially consistent with the TCCs set forth in this Article  28 (as the same may be modified by Exhibit  I attached hereto), and otherwise on commercially reasonable terms that are reasonably acceptable to Landlord and Tenant. Landlord shall prepare the initial draft of the Parking Garage Lease, and Tenant shall respond to Landlord’s request for comment within thirty (30) days, and the parties shall repeat such process until the terms have been reasonably and mutually agreed upon. As of the date of the full execution and delivery of the Parking Garage Lease, the terms of this Article 28 (and the corresponding provisions in Exhibit  I attached hereto) shall be deemed deleted and of no further force or effect.

29.33.2 Compliance with Environmental Laws .

Such environmental inspector or auditor may be chosen by Landlord, in its sole discretion, and be performed at Landlord’s sole expense. To the extent that the report prepared upon such inspection, assessment or audit, indicates the presence of Hazardous Materials in violation of Environmental Laws, or provides recommendations or suggestions to prohibit the release, discharge, escape or emission of any Hazardous Materials at, upon, under or within the Premises, or to comply with any Environmental Laws, Tenant shall promptly, at Tenant’s sole expense, comply with such recommendations or suggestions, including, but not limited to performing such additional investigative or subsurface investigations or remediation(s) as recommended by such inspector or auditor. Notwithstanding the above, if at any time, Landlord has actual notice or reasonable cause to believe that Tenant has violated, or permitted any violations of any Environmental Law, then Landlord will be entitled to perform its environmental inspection, assessment or audit at any time, notwithstanding the above mentioned annual limitation, and Tenant must reimburse Landlord for the cost or fees incurred for such as Additional Rent.

Tenant shall be permitted to contract with Provider for the provision of any or all of such services on such terms and conditions as Tenant and Provider may agree. Tenant shall be permitted to contract with other Providers, at Tenant’s election, and subject to prior written notice to Landlord, provided, however, any such Provider shall be a nationally or regionally recognized Provider providing service to Comparable Buildings.

29.36 Climate Measures . Landlord and Tenant acknowledge that it is likely that new Laws will be enacted dealing with energy conservation, C0 ₂ emissions, transportation and other matters related to global climate change (collectively, “ Climate Measures ”) and that existing Climate Measures policies may be implemented through the adoption of new Laws (such new Laws, rules and regulations being collectively referred to herein as “ New Climate Measures ”) which could increase the obligations of, and restrictions on, Landlord related to the Building and/or Project from those which existed on the date of this Lease. Tenant covenants to comply with the requirements of New Climate Measures applicable to Tenant’s use and occupancy of the Premises and to reasonably cooperate with Landlord in connection with satisfying Landlord’s compliance requirements with respect to the New Climate Measures, including, but not limited to, providing Landlord with monitoring data and reporting duties

related to the Premises and its energy and water consumption, and trash and composting volumes and weights, if required by such New Climate Measures. Tenant shall not, however, be required to make any Alterations to the Building or Premises by reason of any New Climate Measures, except to the extent required by Tenant’s particular use of the Premises, as opposed to Tenant’s use of the Premises for general office or administration use. Furthermore, Tenant acknowledges that Landlord may have or may adopt policies and procedures with respect to energy and carbon reduction measures, including energy efficient bulbs in task lighting; use of lighting controls; daylighting measures to avoid overlighting of displays or interior spaces; closing shades in the Premises to avoid overheating the space; turning off lights and equipment at the end of the work day; purchasing ENERGY STAR® qualified equipment, including but not limited to lighting, office equipment, commercial and residential quality kitchen equipment, vending and ice machines; purchasing products certified by the U.S. EPA’s Water Sense® program; as well as whole-building operations and maintenance issues including chemical use; indoor air quality; energy efficiency; water efficiency; recycling programs; exterior maintenance programs; and systems upgrades to meet green building energy, water, indoor air quality, and lighting performance standards.
