Tenant shall reimburse Landlord for its reasonable attorneys' fees and other expenses incurred in connection with considering any request for its consent to a Transfer. If Landlord consents to a proposed Transfer, then the proposed transferee shall deliver to Landlord a written agreement whereby it expressly assumes the Tenant's obligations hereunder (however, any transferee of less than all of the space in the Premises shall be liable only for obligations under this Lease that are properly allocable to the space subject to the Transfer, and only to the extent of the rent it has agreed to pay Tenant therefor). Landlord's consent to a Transfer shall not release Tenant from performing its obligations under this Lease, but rather Tenant and its transferee shall be jointly and severally liable therefor. Landlord's consent to any Transfer shall not waive Landlord's rights as to any subsequent Transfers. If an Event of Default occurs while the Premises or any part thereof are subject to a Transfer, then Landlord, in addition to its other remedies, may collect directly from such transferee all rents becoming due to Tenant and apply such rents against Tenant's rent obligations. Tenant authorizes its transferees to make payments of rent directly to Landlord upon receipt of notice from Landlord to do so. (b) Landlord may, within 30 days after submission of Tenant's written notification of intent to Transfer, cancel this Lease (or, as to a subletting or assignment, cancel as to the portion of the Premises proposed to be sublet or assigned) effective 30 days after receiving notice of intent to Transfer. If Landlord cancels this Lease as to any portion of the Premises, then this Lease shall cease for such portion of the Premises and Tenant shall pay to Landlord all rent accrued through the cancellation date relating to the portion of the Premises covered by the proposed Transfer. Thereafter, Landlord may lease such portion of the Premises to the prospective transferee (or to any other person) without liability to Tenant. (c) Tenant hereby assigns, transfers and conveys all consideration received by Tenant under any Transfer, which are in excess of the rents payable by Tenant under this Lease plus reasonable costs incurred by Tenant in connection with such reletting. Tenant shall hold such amounts in trust for Landlord and pay them to Landlord within ten days after receipt. (d) Notwithstanding anything to the contrary contained in subpart (2) of Section 14(a) above, Tenant may assign the Lease without Landlord's consent to any of the following (a "Permitted Transferee"), provided that the Permitted Transferee's financial condition, creditworthiness and business reputation following the transfer are equal to or exceed those of Tenant: (i) any successor corporation or other entity resulting from a merger or consolidation of Tenant; (ii) any purchaser of all or substantially all of Tenant's assets; or (iii) any entity which controls, is controlled by, or is under common control with Tenant. Tenant shall give Landlord thirty (30) days prior written notice of such assignment or sublease. Any Permitted Transferee shall assume in writing all of Tenant's obligations under this Lease. Tenant shall nevertheless at all times remain fully responsible and liable for the payment of rent and the performance and observance of all of Tenant's other obligations under this Lease. Nothing in this paragraph is intended to nor shall permit Tenant to transfer its interest under this Lease as part of a fraud or subterfuge to intentionally avoid its obligations under this Lease (for example, transferring its interest to a shell corporation that subsequently files a bankruptcy), and any such transfer shall constitute an Event of Default hereunder. 15. CONDEMNATION. If more than 50% of the Premises or 25% of the Building or Land is taken for any public or quasi-public use by right of eminent domain or private purchase in lieu thereof (a "TAKING"), and the Taking prevents or materially interferes with the use of the Premises for the purpose for which they were leased to Tenant, (including a data center) either party may terminate this Lease by delivering to the other written notice thereof within 30 days after the Taking, in which case rent shall be abated during the unexpired portion of the Term, effective on the date of such Taking. If (a) less than 50% of the Premises or 25% of the Building or Land are subject to a Taking or (b) more than 50% of the Premises or 25% of the Building or Land are subject to a Taking, but the Taking does not prevent or materially interfere with the use of the Premises for the purpose for which they were leased to Tenant (including a data center), then neither party may terminate this Lease, but the rent payable during the unexpired portion of the Term shall be reduced to such extent as may be fair and reasonable under the circumstances. All compensation awarded for any Taking shall be the property of Landlord and Tenant assigns any interest it may have in any such award to Landlord; however, Landlord shall have no interest in any award made to Tenant for loss of business or goodwill or for the taking of Tenant's trade fixtures, the cost of relocating Tenant and/or disruption of Tenant's business, if a separate award for such items is made to Tenant. 16. SURRENDER OF PREMISES; HOLDING OVER. (a) No agreement to accept a surrender of the Premises shall be valid unless it is in writing and signed by Landlord.

Additionally, Tenant shall remove such alterations, additions, improvement, fixtures, equipment, wiring, furniture, and other property as Landlord may request, provided such request is made within fifteen (15) days after the end of the Term and provided that the installation or construction of 6 10 the applicable alteration, improvement, additions, fixture or wiring was not consented to by Landlord in writing (unless at the time of consent, Landlord informed Tenant that such item would need to be removed upon expiration of the Lease).

All work required of Tenant under this Section 16 (a.) shall be coordinated with Landlord and be done in good and workmanlike manner, in accordance with all Laws, and so as not to damage the Building or unreasonably interfere with other tenants' use of their premises.

(b) If Tenant fails to vacate the Premises at the end of the Term, then Tenant shall be a Tenant at will and Tenant shall pay, in addition to the other rent due hereunder, a daily base rental equal to 200% of the daily Base Rent payable during the last month of the Term. Additionally, Tenant shall defend, indemnify, and hold harmless Landlord from any damage, liability and expense (including attorneys' fees and expenses) incurred because of such holding over. No payments of money by Tenant to Landlord after the Term shall reinstate, continue or extend the Term, and no extension of this Term shall be valid unless it is in writing and signed by Landlord and Tenant. 17. QUIET ENJOYMENT.

EVENTS OF DEFAULT. Each of the following events shall constitute an "EVENT OF DEFAULT" under this Lease: (a) Tenant fails to pay any rent when due or any payment or reimbursement required under any other lease with Landlord when due, and in either case such failure continues for a period of five days from the date Landlord delivers written notice of such failure; provided, however, that Landlord shall not be required to deliver written notice more than three (3) times in any given 12 month period or more than six (6) times during the Term, and subsequent to any such third notice in 12 months, or any such sixth notice during the Term, any failure to pay rent or any other sum when due shall be an immediate Event of Default without notice.

(b.), and (C) an amount equal to (i) the total rent that Tenant would have been required to pay for the remainder of the Term discounted to present value at a per annum rate equal to the rate of interest set forth for 26-week U.S. governmental bills sold at a discount from face value in units of $10,000 to $1,000,000 as published on the date this Lease is terminated by The Wall Street Journal, Southwest Edition, in its listing of "Money Rates" under the heading "Treasury Bills" (or, if no such rate is published, the "Discount Rate" as published on such date under the "Money Rates" listing), minus (ii) the then present fair rental value of the Premises for such period, similarly discounted; or (2) Terminate Tenant's right to possess the Premises without terminating this Lease by giving written notice thereof to Tenant, in which event Tenant shall pay to Landlord (A) all rent and other amounts accrued hereunder to the date of termination of possession, (B) all amounts due from time to time under Section 19 (b.), and (C) all rent and other sums required hereunder to be paid by Tenant during the remainder of the Term, diminished by any net sums thereafter received by Landlord through reletting the Premises during such period; Landlord shall use commercially reasonable efforts to mitigate Tenant's damages however, Landlord shall not be obligated to relet the Premises and shall not be liable for, nor shall Tenant's obligations hereunder be diminished because of, Landlord's failure to relet the Premises or to collect rent due for a reletting. Tenant shall not be entitled to the excess of any consideration obtained by reletting over the rent due hereunder. Reentry by Landlord in the Premises shall not affect Tenant's obligations hereunder for the unexpired Term; rather, Landlord may, from time to time, bring action against Tenant to collect amounts 7 11 due by Tenant, without the necessity of Landlord's waiting until the expiration of the Term. Unless Landlord delivers written notice to Tenant expressly stating that it has elected to terminate this Lease, all actions taken by Landlord to exclude or dispossess Tenant of the Premises shall be deemed to be taken under this Section 19(a)(2). If Landlord elects to proceed under this Section 19(a)(2), it may at any time elect to terminate this Lease under Section 19 (a) (1). Additionally, after written notice of a default which remains uncured for more than 30 days, Landlord may alter locks or other security devices at the Premises to deprive Tenant of access thereto, and Landlord shall not be required to provide a new key or right of access to Tenant. (b) Tenant shall pay to Landlord all direct reasonable costs incurred by Landlord (including court costs and reasonable attorneys' fees and expenses) in (1) obtaining possession of the Premises, (2) removing and storing Tenant's or any other occupant's property, (3) repairing, restoring, altering, remodeling, or otherwise putting the Premises into condition acceptable to a new tenant, (4) if Tenant is dispossessed of the Premises and this Lease is not terminated, reletting all or any part of the Premises (including brokerage commissions, cost of tenant finish work, and other costs incidental to such reletting), (5) performing Tenant's obligations which Tenant failed to perform, and (6) enforcing, or advising Landlord of, its rights, remedies, and recourses. Landlord's acceptance of rent following an Event of Default shall not waive Landlord's rights regarding such Event of Default. Landlord's receipt of rent with knowledge of any default by Tenant hereunder shall not be a waiver of such default, and no waiver by Landlord of any provision of this Lease shall be deemed to have been made unless set forth in writing and signed by Landlord. No waiver by Landlord of any violation or breach of any of the terms contained herein shall waive Landlord's rights regarding any future violation of such term or violation of any other term. If Landlord repossesses the Premises pursuant to the authority herein granted, then Landlord shall have the right to (A) keep in place and use or (B) remove and store, at Tenant's expense, all of the furniture, fixtures, equipment and other property in the Premises, including that which is owned by or leased to Tenant at all times before any foreclosure thereon by Landlord or repossession thereof by any lessor thereof or third party having a lien thereon. Landlord may relinquish possession of all or any portion of such furniture, fixtures, equipment and other property to any person (a "CLAIMANT") who presents to Landlord a copy of any instrument represented by Claimant to have been executed by Tenant (or any predecessor of Tenant) granting Claimant the right under various circumstances to take possession of such furniture, fixtures, equipment or other property; provided Landlord is reasonable in believing that the instrument is authentic and legal. Landlord may, at its option and without prejudice to or waiver of any rights it may have, (i) escort Tenant to the Premises to retrieve any personal belongings of Tenant and/or its employees not covered by the Landlord's statutory lien or (ii) obtain a list from Tenant of the personal property of Tenant and/or its employees that is not covered by the Landlord's statutory lien and make such property available to Tenant and/or Tenant's employees; however, Tenant first shall pay in cash all costs and estimated expenses to be incurred in connection with the removal of such property and making it available. The rights of Landlord herein stated are in addition to any and all other rights that Landlord has or may hereafter have at law or in equity, and Tenant agrees that the rights herein granted Landlord are commercially reasonable. 20. LANDLORD'S DEFAULT. If Landlord fails to perform any of its obligations hereunder within 30 days after written notice from Tenant specifying such failure, Tenant's exclusive remedy shall be an action for damages. Unless Landlord fails to so cure such default after such notice, Tenant shall not have any remedy or cause of action by reason thereof. Except for gross negligence or willful misconduct, Liability of Landlord to Tenant for any default by Landlord, shall be limited to actual, direct, but not consequential, damages therefor and shall be recoverable only from the interest of Landlord in the Building and the Land, and neither Landlord nor Landlord's owners shall have any personal liability therefor. 21. MORTGAGES. (a) This Lease shall be subordinate to any deed of trust, mortgage or other security instrument (a "MORTGAGE"), and any ground lease, master lease, or primary lease (a "PRIMARY LEASE") that now or hereafter covers any portion of the Premises (the mortgagee under any Mortgage or the lessor under any Primary Lease is referred to herein as "LANDLORD'S MORTGAGEE"), and to increases, renewals, modifications, consolidations, replacements, and extensions thereof. However, any Landlord's Mortgagee may elect to subordinate its Mortgage or Primary Lease (as the case may be) to this Lease by delivering written notice thereof to Tenant. The provisions of this Section 21. shall be self-operative, and no further instrument shall be required to effect such subordination; however, Landlord shall deliver to Tenant, and Tenant shall execute from time to time within ten days after delivery thereof to Tenant, an instrument from each Landlord's Mortgagee evidencing the subordination of this Lease to any such Mortgage or Primary Lease (which instrument shall include a non-disturbance provision in favor of Tenant and shall be on Landlord's Mortgagee's standard form). (b) Tenant shall attorn to any party succeeding to Landlord's interest in the Premises, whether by purchase, foreclosure, deed in lieu of foreclosure, power of sale, termination of lease, or otherwise, upon such party's request, and shall execute such agreements confirming such attornment as such party may reasonably request. Tenant shall not seek to enforce any remedy it may have for any default on the part of Landlord without first giving written notice by certified mail, return receipt requested, specifying the default in reasonable detail to any Landlord's Mortgagee whose address has been given to Tenant, and affording such Landlord's Mortgagee a reasonable opportunity to perform Landlord's obligations hereunder. (c) Notwithstanding any such attornment or subordination of a Mortgage or Primary Lease to 8 12 this Lease, the Landlord's Mortgagee shall not be liable for any acts of any previous landlord, shall not be obligated to install the Shell or Initial Improvements, and shall not be bound by any amendment to which it did not consent in writing nor any payment of rent made more than one month in advance. 22. ENCUMBRANCES. Tenant has no authority, express or implied, to create or place any lien or encumbrance of any kind or nature whatsoever upon, or in any manner to bind Landlord's property or the interest of Landlord or Tenant in the Premises or to charge the rent for any claim in favor of any person dealing with Tenant, including those who may furnish materials or perform labor for any construction or repairs.

Landlord, at its sole cost and expense, shall complete construction of the shell of the Building including the roof, slab, exterior walls and site work (the "SHELL IMPROVEMENTS"). All such construction shall be completed by Landlord in a good and workmanlike manner and in accordance with all applicable laws and regulations. 2. Before the commencement of interior construction the Tenant, at its sole cost and expense, shall provide to Landlord for its approval final working drawings, prepared by an architect that has been approved by Landlord (which approval shall not be unreasonably withheld), of all improvements that Tenant proposes to install in the Premises; such working drawings shall include the partition layout, ceiling plan, electrical outlets and switches, telephone outlets, HVAC, mechanical and plumbing systems of the Building, and detailed plans and specifications for the construction of the improvements called for under this Exhibit in accordance with all applicable governmental laws, codes, rules, and regulations. Landlord's approval of such working drawings shall not be unreasonably withheld or delayed, provided that (a) they comply with all applicable governmental laws, codes, rules, and regulations, (b) such working drawings are sufficiently detailed to allow construction of the improvements in a good and workmanlike manner, (c) the improvements depicted thereon conform to the rules and regulations promulgated from time to time by the Landlord for the construction of tenant improvements (a copy of which has been delivered to Tenant), and (d) the materials used are building standard (including doors, ceiling tiles, lights and occupancy sensors). As used herein, "WORKING DRAWINGS" shall mean the final working drawings approved by Landlord, as amended from time to time by any approved changes thereto, and "INITIAL IMPROVEMENTS" shall mean all improvements to be constructed in accordance with and as indicated on the Working Drawings. Approval by Landlord of the Working Drawings shall not be a representation or warranty of Landlord that such drawings are adequate for any use, purpose, or condition, or that such drawings comply with any applicable law or code, but shall merely be the consent of Landlord to the performance of the Initial Improvements. Tenant shall, at Landlord's request, sign the Working Drawings to evidence its review and approval thereof. All changes in the Initial Improvements must receive the prior written approval of Landlord and upon completion of the Initial Improvements, Tenant shall furnish Landlord with an accurate, reproducible "as-built" plan (e.g., sepia) and a CADD disk of the improvements as constructed, which plan shall be incorporated into this Lease by this reference for all purposes. 3. Upon substantial completion of the Shell Improvements by Landlord, Tenant shall be responsible for constructing and installing the Initial Improvements. Tenant agrees to file for all required building and signage permits necessary for the construction of the Initial Improvements and to use good faith and diligent efforts to obtain all such permits. The cost of the pursuit of such permits shall be borne by Tenant; however, Landlord will provide its cooperation in connection therewith and, if necessary, shall join in such applications, and execute such other documents, as Tenant may reasonably request for such purposes. The Initial Improvements shall be diligently performed by contractors and subcontractors reasonably acceptable to Landlord in a good and workmanlike manner that is free of defects and is in strict conformance with the Working Drawings and all applicable governmental laws, codes, rules, and regulations. Tenant and its contractors and subcontractors shall be required to maintain such liability and builder's risk insurance during construction of the Initial Improvements as is reasonably required by Landlord. 4. If completion of the Initial Improvements is delayed beyond November 15, 1998 for any reason other than Landlord's failure to substantially complete construction of the Shell Improvements on or before October 15, 1998, then, notwithstanding any provision to the contrary in this Lease, Tenant's obligation to pay Basic Rent and Tenant's Proportionate Share of Operating Expenses hereunder shall commence on November 15, 1998. If the Premises are not ready for occupancy and the Initial Improvements are not substantially completed (as reasonably determined by Landlord) on November 15, 1998 due to Landlord's failure to timely complete the Shell Improvements, then the Commencement Date shall be sixty (60) days after Landlord delivers the Premises in Shell Condition. 5. Landlord shall provide to Tenant a construction allowance (the "CONSTRUCTION ALLOWANCE") equal to the lesser of (a) $20.00 per usable square foot in that portion of the Premises initially delivered to Tenant or (b) the Total Construction Costs, as adjusted for any approved changes to the Initial Improvements. 6. Tenant shall bear the entire cost of constructing the Initial Improvements (including, without limitation, costs of design, engineering, construction, labor and materials, additional janitorial services, related taxes and insurance costs, all of which costs are herein collectively called the "TOTAL CONSTRUCTION COSTS") in excess of the Construction Allowance. Landlord shall advance the Construction Allowance at such time as Tenant has furnished to Landlord a certificate of occupancy for the Premises, lien waivers) from Tenant's general contractor(s) establishing that all bills for labor and materials incorporated in the Initial Improvements have been paid, and a certificate from Tenant's architect certifying that the Initial Improvements have been completed in accordance with the Working Drawings. Notwithstanding the foregoing, at Tenant's request Landlord will fund portions of the Construction Allowance monthly (on the 25th day of each month) for portions of the Initial Improvements actually completed during the previous month, so long as Tenant delivers to Landlord on or before the 10th day of the month a draw request along with lien waivers from all contractors and subcontractors and a certificate from the Tenant's architect's stating that the requested funds are for improvements which have been incorporated into the Premises in accordance with the Working Drawings. In no event shall Landlord be required to reimburse Tenant for costs in excess of the Construction Allowance, as such excess costs will remain the sole responsibility of Tenant.
