Landlord's consent shall not be considered unreasonably withheld if: 1. the proposed transferee's financial responsibility does not meet the same criteria Landlord uses to select Building tenants; 2. the proposed transferee's business is not suitable for the Building considering the business of the other tenants and the Building's prestige or 18 would result in a violation of an exclusive right granted to another tenant in the Building; 3. the proposed use is different than the Permitted Use; 4. the proposed transferee is a government agency whose operations involve an average number of daily visits by non-employees which is materially inconsistent with the character of the Park, or occupant of the Building; or 5.

The preceding sentence shall not apply whenever Tenant is a corporation the outstanding stock of which is listed on a recognized security exchange, or if at least eighty per cent (80%) of its voting stock is owned by another corporation, the voting stock of which is so listed.

B. Except for items for which Landlord is responsible under the Work Letter Agreement, before any repairs, alterations, additions, improvements, or construction are undertaken by or on behalf of Tenant, Tenant shall carry and maintain, at its expense, or Tenant shall require any contractor performing work on the Premises to carry and maintain, at no expense to Landlord, in addition to worker's compensation insurance as required by the jurisdiction in which the Building is located, All Risk Builder's Risk Insurance in the amount of the replacement cost of any alterations, additions or improvements (or such other amount reasonably required by Landlord) and Commercial General Liability Insurance (including, without limitation, Contractor's Liability coverage, Contractual Liability coverage, Completed Operations coverage, a Broad Form Property Damage coverage and Contractor's Protective liability) written on an occurrence basis with a minimum combined single limit of Two Million Dollars ($2,000,000); such limit may be accomplished by means of an umbrella policy. C. Any company writing any insurance which Tenant is required to maintain or cause to be maintained pursuant to the terms of this Lease (all such insurance as well as any other insurance pertaining to the Premises or the operation of Tenant's business therein being referred to as "Tenant's Insurance"), as well as the form of such insurance, shall at all times be subject to Landlord's reasonable approval, and each such insurance company shall have an A.M.

For the 25 purpose of the foregoing waiver, the amount of any deductible applicable to any loss or damage shall be deemed covered by, and recoverable by the insured under the insurance policy to which such deductible relates.

Best rating of "A-7" or better and shall be licensed and qualified to do business in the state in which the Premises are located. The cost of such insurance shall be included as a part of the Basic Costs, and payments for losses thereunder shall be made solely to Landlord or the Mortgagees of Landlord as their interests shall appear. XIX. CASUALTY DAMAGE. A. DAMAGE DIRECTLY AFFECTING PREMISES. If any portion of the Premises is rendered untenantable by damage from any cause, or if any casualty to any portion of the Building or Common Areas materially impairs Tenant's use of, or access to, the Premises or reduces the parking available to Tenant and/or its invitees below the minimum amount required by law, the following shall apply: 1. DETERMINATION OF EXTENT OF DAMAGE. Landlord shall promptly (in any event, within 45 days following the date of the casualty), notify Tenant In writing as to how long, in Landlord's reasonable judgment, it will take to substantially restore the damage (ignoring any absence of insurance proceeds or delays in receiving the same). If Landlord fails to notify Tenant within such 45 day period and such failure continues for ten (10) days after written notice 26 from Tenant, Landlord's failure to so notify Tenant shall, if Tenant so chooses, be deemed to be Landlord's determination that such restoration will take longer than 240 days (measured from the date of the casualty). 2. RIGHTS TO TERMINATE FOLLOWING MAJOR DAMAGE OR DAMAGE NEAR END OF TERM. In the event that Landlord determines that such substantial restoration will take longer than 240 days (measured from the date of the casualty), or in the event that Landlord determines that such damage is restorable within a shorter period but the remaining term of this Lease following such restoration period is less than 2.5 times as long as such restoration period, then in either case Landlord or Tenant may terminate this Lease by irrevocable written notice to the other within 30 days following Tenant's receipt of Landlord's determination (or within 30 days following the 45th day following the date of the casualty, in the event that Landlord's determination is not timely delivered). Tenant shall not have the foregoing termination right in the event that Landlord notifies Tenant (within the 45-day period described above) that, notwithstanding the fact that substantial restoration will take longer than 240 days, substantial restoration of all damage to the Premises and all aspects of the damage to the Building and Common Areas which materially impair Tenant's available parking and/or access to the Premises has or would with the passage of time have, the rights to extend this Lease and (b) Tenant can be accomplished within 240 days of the casualty. Any termination by Landlord due solely to the fact that the remaining term of this Lease following such restoration period will be less than 2.5 times as long as such restoration period shall not be effective in the event that (a) Tenant then irrevocably notifies Landlord in writing, within 10 business days following Landlord's termination notice, that Tenant is exercising such extension. 3. RESTORATION. In the event that, following the occurrence of any damage described in Section XIX.A, this Lease is not terminated , (a) Landlord shall promptly commence and diligently proceed to restore the damage to the Premises and to all aspects of the Building and Common Areas necessary to remedy any material impairment to access to the Premises, except to the extent that the damage relates to aspects of the Premises that were made or installed by Tenant and were not required to be insured by Landlord hereunder, and (b) Tenant shall promptly commence and diligently proceed to restore all aspects of the Premises that were made or installed by Tenant and were not required to be insured by Landlord hereunder, and Tenant shall present Landlord with evidence satisfactory to Landlord of Tenant's ability to pay such costs prior to Landlord's commencement of repair and restoration of the Premises. Both Landlord's and Tenant's restoration obligations hereunder 27 shall be effective regardless of whether the damage is covered by insurance (except as otherwise expressly provided herein) and regardless of any delays in obtaining insurance proceeds. 4. ADDITIONAL TERMINATION RIGHTS. In the event that, for any reason, all damage required to be restored by Landlord is not substantially restored on or before the later of the 240th day following its occurrence or the date set forth in Landlord's initial notice of the estimated period of time for restoration (the later of such dates being referred to as the "Outside Completion Date"), and in the event that such nonrestoration involves the Premises or materially impairs access to the Premises or reduces the parking available to Tenant and/or its invitees below the minimum amount required by law, Tenant shall have the right, within 10 business days thereafter, to terminate this Lease by irrevocable written notice to Landlord; and Tenant shall thereafter have the same right to terminate this Lease within 10 business days following the 30th, 60th and 120th days following the Outside Completion Date. Notwithstanding the foregoing, if Landlord reasonably determines, at any time prior to the completion of the restoration work, that such restoration is not likely to be completed by the applicable Outside Completion Date (or such 30, 60 or 120 day periods, as applicable), Landlord shall be entitled to provide Tenant with written notice thereof, which notice shall advise Tenant of Landlord's revised estimate of the date on which the restoration work will be substantially completed. Tenant, within 1 0 business days after receipt of Landlord's notice, shall be entitled to terminate this Lease by written notice to Landlord. If Tenant does not terminate this Lease within such 10 business day period, the date set forth in Landlord's revised estimate shall be considered to be the Outside Completion Date for purposes hereof. B. OTHER DAMAGE TO BUILDING OR PARK. In the event that 20% or more of the Building or Park is destroyed, or In the event that 1) the cost to repair any damage to the Building or Park caused by a casualty is greater than the lesser of $200,000.00 and the then remaining net income that will be payable to Landlord under this Lease for the remainder of the Lease Term, and 2) either (a) the casualty was of a nature against which Landlord was not insured (and was not required to be insured hereunder) or (b) the casualty was of a nature with respect to which the applicable property insurance proceeds are ultimately paid to any mortgagee, ground lessor or other third party, then in any such event Landlord shall have the right to terminate this Lease by irrevocable written notice to Tenant within 45 days following the occurrence of the damage, but only in the event that Landlord (i) terminates the leases of all tenants similarly situated in relation to the damage, and (ii) does not restore such damage within 18 months following the date of the casualty. The percentages 28 of destruction referred to In this paragraph shall be determined by dividing the cost of the applicable restoration by the replacement cost of the entire Building (or Park, as applicable). C. ADJUSTMENT OF RENT. Following the occurrence of any damage described in this Article XIX, the Base Rental and Additional Base Rental shall each be proportionately abated to the extent that the Premises are thereby rendered unusable by Tenant in its business from the date of such casualty until the earlier of a. the date on which the Premises (or part thereof so rendered unusable) are again usable or b. the date on which (but only to the extent) Tenant again uses the Premises (or part thereof rendered unusable) in its business (and such rents shall be 100% abated in the event that no less than 30% of the Premises is rendered unusable by Tenant and Tenant reasonably elects not to use the remaining partial Premises pending restoration). Except for the foregoing rent abatement and except as otherwise expressly provided herein, Landlord shall have no liability to Tenant for any costs, damages or other losses incurred by Tenant in connection with any casualty to the Premises or Building. D. EFFECTIVE TERMINATION DATE. The effective date of any termination by Landlord or Tenant under this Article XIX shall be the date on which Tenant reasonably ceased, or ceases, to use the Premises for its ordinary business operations as the result of the casualty and, in the event that Tenant is still so using the Premises at the time of the notice of termination, such effective date shall be a date specified by the terminating party in such notice of termination, which date shall not be (i) later than the 60th day following such notice if Landlord is the terminating party; or (ii) earlier than the 60th day following such notice if Landlord is the terminating party; provided that, if both parties effectively give such termination notices, Tenant's effective date shall apply. E. WAIVER OF INCONSISTENT LAWS. Landlord and Tenant hereby waive the provisions to any law from time to time in effect during the Lease Term relating to the effect upon leases of partial or total destruction of leased property. Landlord and Tenant agree that their respective rights in the event of any damage to or destruction of the Premises shall be those specifically set forth herein. XX. DEMOLITION. INTENTIONALLY OMITTED. XXI. CONDEMNATION. If 1. the whole or any substantial part of the Premises or 2. any portion of the Building or Park which would leave the remainder of the Building 29 unsuitable for use as an office building comparable to its use on the Commencement Date, shall be taken or condemned for any public or quasi-public use under governmental law, ordinance or regulation, or by right of eminent domain, or by private purchase in lieu thereof, then Landlord may, at its option, terminate this Lease, by written notice given no later than sixty (60) days prior to the date the physical taking shall occur, effective as of the date the physical taking of said Premises or said portion of the Building or Park shall occur. Notwithstanding the foregoing, if the whole or any substantial part of the Premises shall be taken or condemned for any public or quasipublic use under governmental law, ordinance or regulation, or by right of eminent domain, or by private purchase in lieu thereof, Tenant shall also have the right to terminate this Lease effective as of the date the physical taking of the Premises occurs. Such right to terminate shall be exercised by written notice to Landlord within thirty (30) days after the date on which Tenant is first notified of the taking. In the event this Lease is not terminated, the Rentable Area of the Building, the Rentable Area of the Premises and Tenant's Pro Rata Share shall be appropriately adjusted. In addition, Rent for any portion of the Premises so taken or condemned shall be abated during the unexpired term of this Lease effective when the physical taking of said portion of the Premises shall occur. All compensation awarded for any such taking or condemnation, or sale proceeds in lieu thereof, shall be the property of Landlord, and Tenant shall have no claim thereto, the same being hereby expressly waived by Tenant, except for any portions of such award or proceeds which are specifically allocated by the condemning or purchasing party for the taking of or damage to trade fixtures of Tenant, relocation expenses and tenant improvements paid for by Tenant, which Tenant specifically reserves to itself. XXII. EVENTS OF DEFAULT. The following events shall be deemed to be events of default under this Lease: A. Tenant shall fall to pay any Base Rental, Additional Base Rental or other Rent under this Lease on or before the 5th business day following Tenant's receipt of written notice from Landlord that Tenant failed to pay such amount when due (hereinafter sometimes referred to as a "Monetary Default"). B. Any failure by Tenant (other than a Monetary Default) to comply with any term, provision or covenant of this Lease, which failure is not cured within twenty (20) days after delivery to Tenant of notice of the occurrence of such failure, provided that (i) if any such failure creates a hazardous condition, such failure must be cured Immediately; and (ii) if such failure cannot reasonably be cured within such twenty (20) days, Tenant shall not be in default hereunder so long as Tenant commences such cure within such 20 30 days and thereafter diligently prosecutes such cure to completion. C.

Upon the occurrence of any event or events of default under this Lease, whether enumerated in Article XXII or not, Landlord shall have the option to pursue any one or more of the following remedies 1. Terminate this Lease, in which event Tenant shall immediately surrender the Premises to Landlord. If Tenant fails to surrender the Premises upon termination of the Lease hereunder, Landlord may without prejudice to any other remedy which it may have, enter upon and take 31 possession of the Premises and expel or remove Tenant and any other person who may be occupying said Premises, or any part thereof, and Tenant hereby agrees to pay to Landlord on demand the amount of all loss and damage which Landlord may suffer by reason of such termination, whether through inability to relet the Premises on satisfactory terms or otherwise, specifically including but not limited to all Costs of Reletting (hereinafter defined) and any deficiency that may arise by reason of any reletting or failure to relet. 2. Enter upon and take possession of the Premises and expel or remove Tenant or any other person who may be occupying said Premises, or any part thereof, without terminating this Lease. Landlord may (but shall be under no obligation to) relet the Premises or any part thereof for the account of Tenant, in the name of Landlord, without notice to Tenant for such term or terms which may be greater or less than the period which would otherwise have constituted the balance of the Lease Term and on such conditions (which may include concessions, free rent and alterations of the Premises) and for such uses as Landlord in its absolute discretion may determine, and Landlord may collect and receive any rents payable by reason of such relenting. Tenant agrees to pay Landlord on demand all Costs of Reletting and any deficiency that may arise by reason of such reletting or failure to relet. Landlord shall not be responsible or liable for any failure to relet the Premises or any part thereof or for any failure to collect any Rent due upon any such relenting. No such re-entry or taking of possession of the Premises by Landlord shall be construed as an election on Landlord's part to terminate this Lease unless a written notice of such termination is given to Tenant. 3. Enter upon the Premises and do whatever Tenant is obligated to do under the terms of this Lease, and Tenant agrees to reimburse Landlord on demand for any expense which Landlord may incur in thus affecting compliance with Tenant's obligations under this Lease together with interest at the lesser of a per annum rate equal to: a. the Maximum Rate, or b. the Prime Rate plus five percent (5%), and Tenant further agrees that Landlord shall not be liable for any damages resulting to Tenant from such action, unless caused by the negligence or wilful misconduct of Landlord. 4. In order to regain possession of the Premises and to deny Tenant access thereto in any instance in which Landlord has terminated this Lease or Tenant's right to possession, Landlord shall be entitled to exercise any and all rights provided to at law or in equity under the laws of the state and city in which the Building is located. Landlord may, without notice, remove and store, at Tenant's expense, any property belonging to Tenant that remains in the Premises after Landlord has regained possession thereof. 32 5. Terminate this Lease, in which event, Tenant shall immediately surrender the Premises to Landlord and pay to Landlord the sum of: a. all Rent accrued hereunder through the date of termination, and, upon Landlord's determination thereof, b. an amount equal to (i) the total Rent that Tenant would have been required to pay for the remainder of the Lease Term discounted to present value at the prime rate then in effect, minus (ii) the then present fair rental value of the Premises for the remainder of the Lease Term, similarly discounted, after deducting all anticipated Costs of Reletting. Landlord's determination of such amount shall be conclusive and binding on Tenant, and shall be deemed to have been made in good faith, subject only to manifest error. B. For purposes of this Lease, the term "Costs of Reletting" shall mean all costs and expenses incurred by Landlord in connection with the reletting of the Premises, including without limitation, Rent loss during the period the Premises are vacant prior to reletting, the cost of cleaning, renovation, repairs, decoration and alteration of the Premises for a new tenant or tenants, advertisement, marketing, brokerage and legal fees (if and to the extent permitted by law), the cost of protecting or caring for the Premises while vacant, the cost of removing and storing any property located on the Premises, any increase in insurance premiums caused by the vacancy of the Premises and any other out-of-pocket expenses incurred by Landlord including tenant inducements such as the cost of moving the new tenant or tenants and the cost of assuming any portion of the existing lease(s) of the new tenant(s). C. Except as otherwise herein provided, no repossession or re-entering on the Premises or any part thereof pursuant to Article XXIII hereof or otherwise shall relieve Tenant or any Guarantor of its liabilities and obligations hereunder, all of which shall survive such repossession or re-entering. Notwithstanding any such repossession or re-entering by reason of the occurrence of an event of default, Tenant will pay to Landlord the Rent required to be paid by Tenant pursuant to this Lease. D. No right or remedy herein conferred upon or reserved to Landlord is intended to be exclusive of any other right or remedy, and each and every right and remedy shall be cumulative and in addition to any other right or remedy given hereunder or now or hereafter existing by agreement, applicable law or in equity. In addition to other remedies provided in this Lease, Landlord shall be entitled, to the extent permitted by applicable law, to injunctive relief, or to a decree compelling performance of any of the covenants, agreements, conditions or provisions of this Lease, or to any other remedy allowed to 33 Landlord at law or in equity. Forbearance by Landlord to enforce one or more of the remedies herein provided upon an event of default shall not be deemed or construed to constitute a waiver of such default. E. This Article XXIII shall be enforceable to the maximum extent such enforcement is not prohibited by applicable law, and the unenforceability of any portion thereof shall not thereby render unenforceable any other portion. F. If Tenant provides written notice to Landlord of an event or circumstance which requires the action of Landlord with respect to repair and/or maintenance and the continuation of which Is materially impairing Tenant's use or enjoyment of the Premises or Common Areas, and Landlord fails to provide such action within a reasonable period of time, given the circumstances, after the receipt of such written notice, but In no event earlier than thirty 30 days after receipt of such written notice, then Tenant may proceed to take the required action three (3) days after the delivery of an additional written notice to Landlord specifying that Tenant is taking such required action and, if such action was required under the terms of this Lease to be taken by Landlord, then Tenant shall be entitled to prompt reimbursement by Landlord for Tenant's reasonable costs and expenses in taking such action (unless, pursuant to this Lease, Tenant is solely responsible for the cost of such repair). If Landlord fails to pay such amounts within 30 days after written demand, then Tenant shall be entitled to deduct such amount from the Rent payable by Tenant under this Lease, provided, however, if Landlord disputes Tenant's right to receive reimbursement for the costs incurred by Tenant, Landlord shall have the right to place the disputed amount in an escrow account with an independent third party and to have the dispute between Landlord and Tenant resolved by appropriate legal proceedings. Notwithstanding the foregoing, in no event shall Tenant be entitled to (i) perform any work on any portion of the Building systems that serve tenants or occupants of the Building other than or in addition to Tenant, (ii) perform any work that affects the structure of the Building, or (iii) perform any work that requires entry into another tenant's or occupant's premises. XXIV. LIMITATION OF LIABILITY. NOTWITHSTANDING ANYTHING TO THE CONTRARY CONTAINED IN THIS LEASE, THE LIABILITY OF LANDLORD (AND OF ANY SUCCESSOR LANDLORD HEREUNDER) TO TENANT SHALL BE LIMITED TO THE INTEREST OF LANDLORD IN THE BUILDING, AND TENANT AGREES TO LOOK SOLELY TO LANDLORD'S INTEREST IN THE BUILDING FOR THE RECOVERY OF ANY JUDGMENT OR AWARD AGAINST THE LANDLORD, IT BEING INTENDED THAT LANDLORD SHALL NOT BE PERSONALLY LIABLE FOR ANY JUDGMENT OR DEFICIENCY. TENANT 34 HEREBY COVENANTS THAT, PRIOR TO THE FILING OF ANY SUIT FOR AN ALLEGED DEFAULT BY LANDLORD HEREUNDER, IT SHALL GIVE LANDLORD AND ALL MORTGAGEES WHOM TENANT HAS BEEN NOTIFIED HOLD MORTGAGES OR DEED OF TRUST LIENS ON THE PROPERTY, BUILDING OR PREMISES NOTICE AND REASONABLE TIME TO CURE SUCH ALLEGED DEFAULT BY LANDLORD. IN ADDITION, TENANT ACKNOWLEDGES THAT EQUITY OFFICE PROPERTIES, INC. IS ACTING SOLELY IN ITS CAPACITY AS AGENT FOR LANDLORD AND SHALL NOT BE LIABLE FOR ANY OBLIGATIONS, LIABILITIES, LOSSES OR DAMAGES ARISING OUT OF OR IN CONNECTION WITH THIS LEASE, ALL OF WHICH ARE EXPRESSLY WAIVED BY TENANT. XXV. NO WAIVER. Failure of Landlord or Tenant to declare any default immediately upon its occurrence, or delay in taking an action in connection with an event of default shall not constitute a waiver of such default, nor shall it constitute an estoppel against Landlord or Tenant, but Landlord or Tenant shall have the right to declare the default at any time and take such action as is lawful or authorized under this Lease. Failure by Landlord or Tenant to enforce its rights with respect to any one default shall not constitute a waiver of its rights with respect to any subsequent default. Receipt by Landlord of Tenant's keys to the Premises shall not constitute an acceptance or surrender of the Premises. XXVI. EVENT OF BANKRUPTCY. In addition to, and in no way limiting the other remedies set forth herein, Landlord and Tenant agree that if Tenant ever becomes the subject of a voluntary or involuntary bankruptcy, reorganization, composition, or other similar type proceeding under the federal bankruptcy laws, as now enacted or hereinafter amended, then: A. "Adequate protection" of Landlord's interest in the Premises pursuant to the provisions of Section 361 and 363 (or their successor sections) of the Bankruptcy Code, 11 U.S.C. Section 101 et seq., (such Bankruptcy Code as amended from time to time being herein referred to as the "Bankruptcy Code"), prior to assumption and/or assignment of the Lease by Tenant shall include, but not be limited to all (or any part) of the following: the continued payment by Tenant of the Base Rental and all other Rent due and owing hereunder and the performance of all other covenants and obligations hereunder by Tenant; B. "Adequate assurance of future performance" by Tenant and/or any assignee of Tenant pursuant to Bankruptcy Code Section 365 will include (but not be limited to) payment of an additional/new Security Deposit in the 35 amount of two (2) times the then-current monthly Base Rental payable hereunder. C. Any person or entity to which this Lease is assigned pursuant to the provisions of the Bankruptcy Code, shall be deemed without further act or deed to have assumed all of the obligations of Tenant arising under this Lease on and after the effective date of such assignment. Any such assignee shall, upon demand by Landlord, execute and deliver to Landlord an instrument confirming such assumption of liability. D. Notwithstanding anything in this Lease to the contrary, all amounts payable by Tenant to or on behalf of the Landlord under this Lease, whether or not expressly denominated as "Rent", shall constitute "rent" for the purposes of Section 502(b) (6) of the Bankruptcy Code. E. It this Lease is assigned to any person or entity pursuant to the provisions of the Bankruptcy Code, any and all monies or other considerations payable or otherwise to be delivered to Landlord (including Base Rentals and other Rent hereunder), shall be and remain the exclusive property of Landlord and shall not constitute property of Tenant or of the bankruptcy estate of Tenant. Any and all monies or other considerations constituting Landlord's property under the preceding sentence not paid or delivered to Landlord shall be held in trust by Tenant or Tenant's bankruptcy estate for the benefit of Landlord and shall be promptly paid to or turned over to Landlord. F. If Tenant assumes this Lease and proposes to assign the same pursuant to the provisions of the Bankruptcy Code to any person or entity who shall have made a bona fide offer to accept an assignment of this Lease on terms acceptable to the Tenant, then notice of such proposed offer/assignment, setting forth 1. the name and address of such person or entity, 2. all of the terms and conditions of such offer, and 3. the adequate assurance to be provided Landlord to assure such person's or entity's future performance under the Lease, shall be given to Landlord by Tenant no later than twenty (20) days after receipt by Tenant, but in any event no later than ten (10) days prior to the date that Tenant shall make application to a court of competent jurisdiction for authority and approval to enter into such assumption and assignment, and, unless such transfer is to a Permitted Transferee, Landlord shall thereupon have the prior right and option, to be exercised by notice to Tenant given at any time prior to the effective date of such proposed assignment, to accept an assignment of this Lease upon the same terms and conditions and for the same consideration, if any, as the bona fide offer made by such persons or entity, less any brokerage commission which may be payable out of the consideration 36 to be paid by such person for the assignment of this Lease. XXVII. QUIET ENJOYMENT. Tenant shall, and may peacefully have, hold, and enjoy the Premises, subject to the other terms of this Lease (including. without limitation, Article XXX hereof), provided that Tenant pays the Rent herein recited to be paid by Tenant and performs all of Tenant's covenants and agreements herein contained. This covenant and any and all other covenants of Landlord shall be binding upon Landlord and its successors only during its or their respective periods of ownership of the Landlord's Interest hereunder. XXVIII. RELOCATION. INTENTIONALLY OMITTED. XXIX. HOLDING OVER. In the event of holding over by Tenant after expiration or other termination of this Lease or in the event Tenant continues to occupy the Premises after the termination of Tenant's right of possession pursuant to Articles XXII and XXIII hereof, occupancy of the Premises subsequent to such termination or expiration shall be that of a tenancy at sufferance and in no event from month-to-month or year-to-year, but Tenant shall, throughout the entire holdover period, pay rent (on a per month basis without reduction for any partial months during any such holdover) equal to 150% of the sum of the Base Rental and Additional Base Rental due for the period immediately preceding such holding over, provided that in no event shall Base Rental and Additional Base Rental during the holdover period be less than the fair market rental for the Premises. No holding over by Tenant or payments of money by Tenant to Landlord after the expiration of the term of this Lease shall be construed to extend the Lease Term or prevent Landlord from recovery of immediate possession of the Premises by summary proceedings or otherwise. Tenant shall be liable to Landlord for all damage, including any consequential damage, which Landlord may suffer by reason of any holding over by Tenant, and Tenant shall indemnity Landlord against any and all claims made by any other tenant or prospective tenant against Landlord for delay by Landlord in delivering possession of the Premises to such other tenant or prospective tenant. Notwithstanding the foregoing, Tenant shall not be liable for consequential damages unless (1) Landlord notifies Tenant that it has entered into a lease for the Premises or has received a bona fide offer to lease the Premises, and (2) Tenant fails to vacate the Premises within ten (10) days after the date of Landlord's notice. XXX. SUBORDINATION TO MORTGAGES. A. Tenant accepts this Lease subject and subordinate to any mortgage, deed of trust, ground lease or other lien presently existing or 37 hereafter arising upon the Premises, or upon the Building and/or the Park and to any renewals, modifications, refinancings and extensions thereof (any such mortgage, deed of trust, lease or other lien being hereinafter referred to as a "Mortgage", and the person or entity having the benefit of same being referred to hereinafter as a "Mortgagee'), but Tenant agrees that any such Mortgagee shall have the right at any time to subordinate such Mortgage to this Lease on such terms and subject to such conditions as such Mortgagee may deem appropriate in its discretion. This clause shall be self-operative and no further instrument of subordination shall be required. However, Landlord is hereby irrevocably vested with full power and authority to subordinate this Lease to any Mortgage, and Tenant agrees upon demand to execute such further instruments subordinating this Lease, acknowledging the subordination of this Lease or attorning to the holder of any such Mortgage as Landlord may request. The terms of this Lease are subject to approval by the Landlord's existing lender(s) and any lender(s) who, at the time of the execution of this Lease, have committed or are considering committing to Landlord to make a loan secured by all or any portion of the Park, and such approval is a condition precedent to Landlord's obligations hereunder. If any person shall succeed to all or part of Landlord's interests in the Premises whether by purchase, foreclosure, deed in lieu of foreclosure, power of sale, termination of lease or otherwise, and if and as so requested or required by such successor-in-interest, Tenant shall, without charge, attorn to such successor-in-interest if and so long as such successors) agree(s) that Tenant's possession of the Premises and this Lease, including any options to extend the term hereof, any rights of first offer and rights of first refusal, and any other options hereunder, will not be disturbed so long as Tenant is not In default hereunder (subject to any applicable notice and cure periods). Tenant and Landlord each agree that it will from time to time upon request by the other and, within fifteen (15) days of the date of such request, execute and deliver to such persons as the requesting party shall request an estoppel certificate or other similar statement in recordable form certifying that this Lease is unmodified and in full force and effect (or if there have been modifications, that the same is in full force and effect as so modified), stating the dates to which Rent and other charges payable under this Lease have been paid, stating that the requesting party is not in default hereunder (or if the requesting party alleges a default stating the nature of such alleged default) and further stating such other matters as the requesting party shall reasonably require. B. Notwithstanding the foregoing to the contrary, this Lease is contingent upon Landlord providing Tenant with a fully executed non-disturbance, attornment, estoppel and subordination agreement from Landlord's current Mortgagee on the form attached hereto as Exhibit I (the 38 "Non-disturbance Agreement") within ten (10) business days after the full and final execution of this Lease by Landlord and Tenant. Tenant shall execute the Non-disturbance Agreement upon receipt from Landlord and shall return the same to Landlord for execution by Landlord's Mortgagee. In the event that Landlord fails to provide Tenant with the Non-Disturbance Agreement within such ten (10) business day period, Tenant, as its sole remedy, shall have the right to terminate this Lease by written notice to Landlord within ten (10) days after the expiration of such ten (10) day period. Notwithstanding anything herein to the contrary, Landlord shall also be required to provide Tenant with a non-disturbance, subordination and attornment agreement in favor of Tenant from any Mortgagee who comes into existence after the Commencement Date. Such non-disturbance, subordination and attornment agreement in favor of Tenant shall provide that, so long as Tenant is paying the Rent due under this Lease and is not otherwise in default under the Lease, its right to possession and other terms of the Lease shall remain in full force and effect. Such non-disturbance, subordination and attornment agreement may include additional time on behalf of the Mortgagee to cure defaults of the Landlord and provide that a) neither Mortgagee nor any successor in interest shall be bound by (i) any payment of Base Rental, Additional Base Rental or other sum due hereunder for more than one (1) month in advance, or (ii) any amendment or modification of this Lease made without the express written consent of Mortgagee or any successor in interest; b) neither Mortgagee nor any successor in interest will be liable for (i) any act or omission or warranties of any prior landlord (including Landlord), except with regard to any continuing default of which Tenant has provided Mortgagee with written notice and a reasonable opportunity to cure after the date on which Mortgagee takes title to the Building, or (ii) the breach of any warranties or obligations relating to construction of improvements on the Property or any tenant finish work performed or to have been performed by any prior landlord (including Landlord), provided that in the event Mortgagee, after notice and a reasonable opportunity to perform, fails to perform any tenant finish work required to be performed under this Lease with respect to Offering Space A, Offering Space B or any Refusal Space, Tenant shall have the right to perform such work and to offset the reasonable cost thereof against Rent, or (iii) the return of any security deposit, except to the extent such deposits have been received by Mortgagee; c) neither Mortgagee nor any successor in interest shall be subject to any offsets or defenses which Tenant might have against any prior landlord (including Landlord). Notwithstanding the foregoing, Landlord shall use reasonable efforts to attempt to cause any Mortgagee to delete, prior to execution by Tenant and the Mortgagee, any provision of the Mortgagees non-disturbance, subordination and attornment agreement with Tenant that requires Tenant to waive any offsets or defenses which Tenant might have against any prior 39 landlord. XXXI. ATTORNEY'S FEES. In the event that Landlord should retain counsel and/or institute any suit against Tenant for violation of or to enforce any of the covenants or conditions of this Lease, or should Tenant institute any suit against Landlord for violation of any of the covenants or conditions of this Lease, or should either party intervene in any suit in which the other is a party to enforce or protect its interest or rights hereunder, the prevailing party in any such suit shall be entitled to all of its costs, expenses and reasonable fees of its attorneys) (if and to the extent permitted by law) in connection therewith.
