If Purchaser fails to terminate within such 15-day period or fails to deliver the Title and Survey Objections within such 15-day period, then Purchaser shall be deemed to have waived such termination right and approved the Title Commitments, the Title Exception Documents and the Surveys and the title exceptions set forth in the Title Commitments, Title Exception Documents and/or Surveys shall be deemed to be Permitted Exceptions.

If such 30-day

period would end after the initially scheduled Closing Date determined pursuant to the first sentence of Section 15(a) and Seller elects to cure the Title and Survey Objections, Seller shall have the right to extend such initially scheduled Closing Date by the number of days from the first day following the initially scheduled Closing Date to and including the last day of such 30-day period. If Seller elects not to cure all of the Title and Survey Objections or is unable to cure any of the Title and Survey Objections, then (i) Seller shall not be in default hereunder on account thereof and (ii) Purchaser may either (a) elect to terminate this Contract by delivering written notice thereof to Seller within seven (7) days after the expiration of such 30-day period or receipt of Seller's notice that it elects not to cure, or (b) proceed to Closing. If Purchaser so elects to terminate this Contract, then (a) the ▇▇▇▇▇▇▇ Money shall be returned promptly to Purchaser, and (b) Purchaser and Seller shall be relieved of any further obligations under this Contract, save and except for those obligations which expressly survive the termination of this Contract. If Purchaser does not elect to terminate this Contract within such seven-day period, then Purchaser shall be deemed to have accepted the Title Commitments, the Title Exception Documents and the Surveys for all purposes, Purchaser shall no longer be entitled to terminate this Contract due to any objections thereto and all title exceptions included in the Title Commitments, the Title Exception Documents and/or the Surveys shall be deemed to be Permitted Exceptions, other than those items removed or agreed to be removed from the Title Commitments and/or Surveys, as applicable, through Seller's curative actions.

(b) Inspection of Property. At all times prior to Closing, Purchaser shall have the right to perform soil tests, environmental tests and any other investigations (collectively "Investigations") in respect of the Property that Purchaser deems necessary or desirable. Purchaser agrees to begin its Investigations promptly and to diligently pursue same to completion. Subject to paragraph (d) of this Section 10 below, if, within thirty-five (35) days after the Effective Date, the Investigations show the existence of a condition at the Property which has a material and adverse effect on the Property (the "Material and Adverse Condition"), then Purchaser shall have the right to terminate this Contract by delivering (within such 35-day period) written notice thereof to Seller which also sets forth the Material and Adverse Condition. Purchaser agrees to deliver such notice to Seller promptly after it learns of a Material and Adverse Condition. In lieu of termination, Purchaser may request Seller to cure the Material and Adverse Condition, in which event Seller shall have the right, but not the obligation, to take such actions within the next thirty (30) days as are necessary to cure the Material and Adverse Condition. If such 30-day period would end after the initially scheduled Closing Date determined pursuant to the first sentence of Section 15(a) and Seller elects to cure the Material and Adverse Condition(s), Seller shall have the right to extend such initially scheduled Closing Date by the number of days from the first day following the initially scheduled Closing Date to and including the last day of such 30-day period. If Seller elects not to cure all such Material and Adverse Condition(s) or is unable to cure such Material and Adverse Condition(s) within the 30-day period or after having commenced curative action, ceases such action prior to the expiration of the 30-day period, then (i) Seller shall not be in default hereunder on account thereof and (ii) Purchaser may either (a) elect to terminate this Contract by delivering written notice thereof to Seller within seven (7) days after the earlier to occur of the expiration of such 30-day period or Purchaser's receipt of Seller's notice of its election not to cure or its decision to cease curative actions, or (b) proceed to Closing. If Purchaser so elects to terminate this Contract, then (a) the ▇▇▇▇▇▇▇ Money shall be returned promptly to Purchaser, and (b) Purchaser and Seller shall be relieved of any further obligations under this Contract, save and except for those obligations and liabilities which expressly survive the termination of this Contract. If Purchaser (i) fails to send a termination notice or a notice requesting Seller to cure a Material Adverse Condition within the 35-day period required above or (ii) Purchaser does not elect to terminate this Contract within the seven-day period permitted above, then (x) except for the environmental conditions which permit Purchaser to terminate this Contract (absent the timely

cure thereof) under paragraph (e) of this Section, Purchaser shall be deemed to have accepted all Material and Adverse Conditions in respect of the Property, (y) Seller shall have no liability to Purchaser in respect of any Material and Adverse Conditions relating to the Property, and (z) Purchaser shall have waived its termination rights under this paragraph.

(c) Damage from Inspections and Repair Thereof. Purchaser shall use reasonable efforts not to damage any portion of the Property in performing its Investigations, though soil borings will be allowed on the Undeveloped Land. Notwithstanding the preceding sentence, in the event Closing does not occur, Purchaser shall promptly repair, to the extent practical, at Purchaser's sole cost and expense, any damage occurring to the Property in connection with any such Investigations. Purchaser shall indemnify, defend and hold harmless Seller against any physical loss or damage to the Property or any portion thereof, lien claims against the Property or any portion thereof or other damage, injury, claim, cost or expense (including reasonable attorneys' fees and expenses) suffered by Seller as a result of Purchaser's inspections, investigations and/or tests, which indemnity shall survive the termination of this Contract for a period of one (1) year.

(d) Limitation on Investigations. Prior to performing any Investigations of or on the Property, Purchaser shall (i) provide to Seller, at least one (1) business day's notice, which notice shall include a description of the Investigations to be conducted, the approximate location of where the Investigations will be conducted, the date on which the Investigations will be conducted, and the name of the contractor who will perform the Investigations, and (ii) deliver to Seller a certificate of insurance evidencing that the applicable contractor has at least $1,000,000 of commercial general liability insurance coverage.

(e) Forty-five Day Inspection Period. If during the period from the Effective Date until 11:59 P.M. on the forty-fifth (45^th) day after the Effective Date (or if such 45^th day is a Saturday, Sunday, or legal holiday, until 11:59 p.m. on the first business day following such 45^th day) (such period, the "Forty-five Day Period"), any of the following occur, Purchaser shall have the right to terminate this Contract by delivering written notice thereof to Seller prior to the end of the Forty-five Day Period (the "Forty-five Day Termination Right"), provided Purchaser agrees to deliver such notice to Seller promptly after the occurrence of such event:

(i) Purchaser's environmental consultants determine that the Property is contaminated with Hazardous Materials, the cost to remediate same is reasonably estimated to be in excess of $125,000 by Purchaser's environmental consultant, Purchaser delivers to Seller a copy of such determination and estimate and the consultant's report within thirty-five (35) days after the Effective Date, the contamination occurred after September 14, 1999, and Seller elects not to remediate the Hazardous Materials to Purchaser's reasonable satisfaction or is unable to remediate or fails to remediate the Hazardous Materials to Purchaser's reasonable satisfaction prior to the end of the Forty-five Day Period. Within ten (10) days after Seller receives the environmental consultant's determination and report showing existence of Hazardous Materials on the Property, Seller will deliver written notice of whether Seller elects to attempt to remediate the contamination. Even if Seller elects to attempt to remediate, Seller may elect to terminate its remediation attempts, in which event Seller will give Purchaser prompt written notice thereof. If Purchaser exercises its Forty-five Day Termination Right in accordance with this paragraph, the Escrow Agent is hereby directed to return the ▇▇▇▇▇▇▇ Money to Purchaser, this Contract shall terminate as of the date of Purchaser's notice, and the parties shall have no further rights or obligations under this Contract, save and except for those obligations and liabilities which expressly survive the termination of this Contract. If Purchaser fails to exercise timely its Forty-five Day Termination Right, Purchaser shall be deemed to have waived its Forty-five Day Termination Right and Seller shall have no responsibility or obligations with respect to the matters described in this paragraph.

(f) Delivery of Reports, etc. If Purchaser terminates this Contract pursuant to any provision of this Contract or otherwise, Purchaser shall promptly deliver to Seller copies of the reports, surveys, test results, etc. obtained by Purchaser in connection with its due diligence concerning the Property. If Purchaser discovers a Material and Adverse Condition, Purchaser shall promptly deliver to Seller copies of the reports, surveys, tests, etc. which reflect or support the Material and Adverse Condition.

11. CONTRACTS AFFECTING THE PROPERTY.

(a) Terminable Contracts/Rejections of Terminable Contracts. At such time (but no later than the 10^th day after the Effective Date) as Seller, in good faith, believes that it has delivered to Purchaser all contracts affecting the Property that are terminable by the delivery of notice and/or the payment of a specified fee ("Terminable Contracts"), Seller will so notify Purchaser in writing. Purchaser shall have fifteen (15) days thereafter to advise Seller of those Terminable Contracts which Purchaser desires to have terminated (the "Terminable Contract Notice", and the Terminable Contracts covered thereby, the "Rejected Terminable Contracts"). Purchaser shall be deemed to have accepted and, at Closing, will assume each Terminable Contract, other than the Rejected Terminable Contracts. If Purchaser fails to forward the Terminable Contract Notice within the required 15-day period, Purchaser shall be deemed to have assumed all Terminable Contracts. Seller shall forward notices of termination, at Closing, with respect to all Rejected Terminable Contracts. Purchaser acknowledges that a Rejected Terminable Contract shall not be deemed terminated until the required days of notice, if any, are given to the vendor thereunder and that Seller will not be required to give termination notices until the Closing Date. Purchaser will be responsible only for any payments which become due for the thirty (30) day period following Closing under all Rejected Terminable Contracts solely by reason of the passage of the required notice period and Seller agrees to be responsible for any such payments which are required to be paid for the period in excess of the first thirty (30) days (which obligation shall expressly survive Closing).

(b) Accepted Contracts. All contracts listed on Exhibit M (other than the Rejected Terminable Contracts) shall be assigned to Purchaser at Closing. If any fee is payable in connection with the assignment of such contract, Purchaser shall be responsible for the payment of such fee.

12. ADDITIONAL COVENANTS. In addition to the other covenants set forth in this Contract, Seller and/or Purchaser, as applicable, agree to comply with the following covenants:

(a) Operation of the Property. After the Effective Date until the Closing Date, Seller shall (1) operate the Property in the same manner as the Property has been operated; and (2) maintain the Property in the same condition and in the same manner as existed on the Effective Date, ordinary wear and tear and casualty loss excepted.

(b) No Further Leases. Seller shall not enter into any other leases affecting the Property.

(c) No Further Encumbrances. Seller shall not further encumber the Property or allow an encumbrance upon the title to the Property, or modify the terms or conditions of any existing leases, contracts or encumbrances, if any, except for the CSL Lease, without the written consent of Purchaser.

(d) Re-zoning of Property. Seller (i) understands that Purchaser may choose to seek changes in zoning for part or all of the Undeveloped Land, (ii) agrees to cooperate, and to not oppose or interfere, with (A) the initial (but not subsequent) attempt by Purchaser to change the zoning of the Undeveloped Land or any portion thereof to allow residential development as well as development for office, retail or hotel purposes (but for no other purposes), or (B) any necessary zoning change to allow for the development of the Minerals to be conveyed to Purchaser

hereunder, subject to Section 12(i) below, and (iii) agrees to promptly execute any documents necessary to accommodate any such zoning change pursued by Purchaser. The obligations under this paragraph shall survive the Closing of this Contract. The zoning contemplated by this paragraph shall not be a condition precedent to the closing of this Contract.

(e) Intentionally Deleted.

(f) Intentionally Deleted.

(g) Kirkwood Boulevard and ▇.▇. ▇▇▇▇ Road. The Property includes the two (2) tracts of real property consisting of approximately 2.638 acres and 2.519 acres used by Seller as private roadways and which were formerly known and used as portions of Kirkwood Boulevard and ▇.▇. ▇▇▇▇ Road. Such tracts of the property previously used as public roadways and subsequently abandoned are depicted on Exhibit A-3 attached hereto and described on Exhibit H attached hereto and are herein collectively referred to as the "Roadway Land". In addition, there is a portion of the Undeveloped Land consisting of approximately 11.12 acres (as shown on the Overall Site Map) which will be conveyed to Purchaser at Closing and is described on Exhibit I attached hereto on which is located a completed portion of a roadway which is currently private but which has been designed so that it could become a portion of Kirkwood Boulevard, and is herein referred to as "Future Public Boulevard." After Closing, Purchaser intends to work with the City to cause the Roadway Land and the Future Public Boulevard to become public roadways utilizing the names Kirkwood Boulevard and ▇.▇. ▇▇▇▇ Road or such other names (not including the name of Sabre Holdings Corporation or its affiliates) that are approved by the City and Purchaser (the "Required Conversion"). Seller will fully cooperate with Purchaser and the City (at no expense to Seller other than with regard to clauses (iv) and (v) below) in connection with the Required Conversion, including, but not limited to, (i) consenting to the Required Conversion in public hearings and elsewhere, (ii) publicly supporting and, if permitted under applicable law, joining in an application for the Required Conversion, (iii) executing such other documents as are reasonably necessary to cause the Required Conversion to occur, (iv) after the Required Conversion, at Seller's sole cost and expense, removing all security gates that restrict the use of the Roadway Land as public roadways through the Property, and (v) within a reasonable amount of time following the request of the City, at Seller's sole cost and expense, restoring the Roadway Land to the condition that the City currently requires for public roadways. Notwithstanding the preceding sentence, (i) at Seller's sole option, the Roadway Land and Future Public Boulevard may remain private roadways until the earlier of (A) the date all of Seller's employees have vacated the Southlake Building, (B) Purchaser or its successors have commenced construction of the roads or other infrastructure on the Undeveloped Land, (C) January 1, 2008, or (D) the City requires the Roadway Land and Future Public Boulevard be publicly dedicated as a condition to re-platting or re-zoning the Undeveloped Land, (ii) Seller and its employees, agents, guests and contractors shall have the right of free and unimpeded access over and across the Roadway Land and Future Public Boulevard until such time (if ever) that the Required Conversion occurs, which right shall survive Closing and shall run with the land (the "Access Right"), and (iii) Purchaser and its employees, agents, guests and contractors shall have the right of free and unimpeded access over and across the Roadway Land and Future Public Boulevard (even though Seller has exercised its option in clause (i) to keep same private roadways).

(h) Obelisk. A purple obelisk currently exists on a portion of the Developed Land located within the area that is enclosed by walls in and around the Kirkwood Boulevard Interchange Maintenance Area (the "Obelisk"). At Closing, Seller hereby releases any rights it has with respect to the Obelisk, including, but not limited to, any right Seller has to remove the Obelisk or to redesign or in any way modify the Obelisk or to participate in the redesigning or modification of the Obelisk.

(i) Minerals. Purchaser and its mineral lessees will be prohibited from engaging in drilling or mining operations for Minerals on the surface of the Excluded Tracts or within 600 feet from the exterior wall of any of the commercial buildings (excluding any buildings used for parking of motor vehicles) currently located on the Headquarters Tract, but not from drilling operations for Minerals underneath the Excluded Tracts so long as those operations utilize "horizontal drilling" or "directional drilling" from well locations which are not on the Excluded Tracts or within such 600 foot zone. In addition, Purchaser and its mineral lessees will be prohibited from operating a compressor station anywhere on the Property or the Excluded Tracts, unless the following requirements are met: (i) hospital mufflers must be installed, (ii) all compressors must be placed in a building which will be insulated with sound batting so that the noise decibels do not exceed 70 decibels at 300 feet from the compressor station, (iii) all exhaust from any compressor must pass through a hospital muffler at the surface, (iv) "noise walls" must be installed to inhibit and reduce the noise level resulting from compressor operations, and (v) the compressor station may not be located within 600 feet from the exterior wall of any of the commercial building(s) (excluding any buildings used for parking of motor vehicles) currently located on the Headquarters Tract. Other than restrictions which are currently imposed by the City under Ordinances 480-YY and 880, and which may be imposed by the City or other governmental entities in the future, there will be no other restrictions on surface drilling or mining on, in or under any other portion of the Property. Seller hereby reserves the Retained Mineral Interest. In the event Seller owns less than 100% of the Minerals on, in and under the Excluded Tracts, the Retained Mineral Interest will be proportionately reduced by the percentage interest in the Minerals drilled or mined on, in or under the Excluded Tracts that are owned by Seller and are conveyed to Purchaser (for example, if Seller owns and conveys to Purchaser an 80% interest in the Minerals under the Excluded Tracts [because 20% of the Minerals have been previously reserved by a third party unrelated to Seller], then the Retained Mineral Interest would be reduced to a 15.14% non-participating royalty interest in the Minerals under the Excluded Tracts). Purchaser will have the authority to pool the Retained Mineral Interest, provided if Purchaser does pool the Retained Mineral Interest, Purchaser must pool as to all of the Excluded Tracts, and not just a portion of the Excluded Tracts.

(j) Lease. On the date of Closing, Seller, as tenant, shall enter into the lease with Purchaser, as landlord, covering the Southlake Building which shall be in the form of Exhibit C attached hereto.

(k) Kirkwood Boulevard Interchange. Seller and Purchaser agree that (i) Purchaser (or its successors or assigns) will have control over and provide the maintenance and repairs for the Kirkwood Boulevard Interchange Maintenance Area, and (ii) Seller will remain responsible for one-half of the maintenance and repair costs pertaining to the Kirkwood Boulevard Interchange Maintenance Area only until the earlier of (A) the Lease is terminated, or (B) Seller has removed all of its employees from the Southlake Building and a new tenant or subtenant occupies all of the Southlake Building. Seller agrees that its identification sign currently located in the Kirkwood Boulevard Interchange Maintenance Area shall comply with all City ordinances and shall not be enlarged by Seller. Purchaser agrees that such sign may remain in the Kirkwood Boulevard Interchange Maintenance Area so long as Seller is paying one-half of the maintenance and repair costs pertaining to the Kirkwood Boulevard Interchange Maintenance Area.

(l) Restrictions on Parking Knob. Attached hereto as Exhibit B-4 is a legal description of a portion of the Headquarters Tract consisting of approximately 4.34 acres which Seller is retaining (the "Parking Knob"). At Closing, a deed restriction will be recorded against the Parking Knob by Seller so that the Parking Knob may only be improved with parking and landscaping to serve the buildings on the Headquarters Tract (but which will not be used for general office purposes (the "Parking Knob Restriction")), which Parking Knob Restriction shall automatically terminate after ten (10) years.

(m) Restrictions on Office Knob. Attached hereto as Exhibit B-5 is a legal description of a portion of the Headquarters Tract consisting of approximately 0.63 acres which Seller is retaining (the "Office Knob"). Seller covenants with Purchaser that it will not construct a building on the Office Knob or on the adjacent land within thirty (30) feet of the Office Knob (defined herein as the "Adjacent Land") (or on a combination of the Office Knob or Adjacent Land) except for a building which is 40,000 square feet or less in size and which may be used only as an employee fitness center, and/or a server room, and/or as a marketing, demonstration and training facility for Seller's customers and employees, and which shall not be used for office space or otherwise used to house employees or contract workers, temporarily or permanently, except that the building may house employees involved specifically with the employee fitness center, and/or server room, and/or the marketing/demonstration/customer and employee training function described above, which number of employees is estimated at twelve (12) to fifteen (15); provided, however, if such building is less than 20,000 square feet in size, the covenant set forth in this sentence shall not apply to such building. The foregoing covenant will survive the Closing until the first to occur of (a) a period of ten (10) years from the date of Closing, or (b) the date when Seller sells the Headquarters Tract to (i) a third party that does not directly or indirectly own or control Seller, or (ii) any third party that is not owned or directly or indirectly controlled by Seller, and in either case Seller vacates the buildings located thereon. If Seller breaches or threatens to breach the foregoing covenant, then notwithstanding anything contained in Section 16(a) of this Contract to the contrary, Purchaser may thereafter pursue all remedies available to it, either at law or in equity, including, but not limited to, injunctive relief, without the need to file any bond with any court of competent jurisdiction. In addition, a deed restriction will be recorded against the Office Knob by Seller which provides that no building can be constructed either wholly or partially on the Office Knob unless such building conforms with the provisions of this paragraph, including the termination provisions (the "Office Knob Restriction").

(n) Restrictions on Pond Tract. At Closing, a deed restriction will be recorded against a portion of the Pond Tract by Seller (which portion shall be reasonably acceptable to Seller and Purchaser), requiring it be used only to provide irrigation water for landscape on the Excluded Tracts and for no other purpose (the "Pond Restriction"), which Pond Restriction shall automatically terminate after ten (10) years

(s) Assignment. Purchaser shall have the right, upon written notice to Seller, to assign this Contract or any of its right, title or interest to acquire all or any portion of the Property under this Contract to any Affiliate (as hereinafter defined) of Purchaser without the Seller's consent, and

Purchaser may, without the consent of Seller, directly or collaterally assign this Contract to a third party lender for the purpose of securing the Loan (as defined in Section 18 of this Contract). For purposes of this subsection, the term "Affiliate" shall mean any partner of Purchaser, any entity which directly or indirectly controls Purchaser, any person that directly or indirectly controls Purchaser, or any entity controlled directly or indirectly by ▇▇▇▇▇▇ ▇. ▇▇▇▇▇▇▇, or any entity in which ▇▇▇▇▇▇ ▇. ▇▇▇▇▇▇▇ owns at least a 25% direct or indirect interest (provided ▇▇. ▇▇▇▇▇▇▇ also controls voting of such entity).

18. CONTINGENCY. Purchaser acknowledges that Seller does not currently own the Property but Seller agrees to use its commercially reasonable and diligent efforts (including exercising any remedies available to it under the CSL Lease to compel CSL's performance) to acquire it at or prior to Closing from CSL, the current owner. In the event Seller does not acquire the Property at or prior to Closing for any reason other than Seller's breach of its obligations under the previous sentence, then Closing shall be automatically extended for up to ninety (90) days (with Closing to occur two (2) business days after such acquisition), and in the event Seller has not acquired the Property by the expiration of such 90-day period, same shall not be a default by Seller hereunder, but at the option of either party (to be exercised by written notice delivered to the other party, Escrow Agent and Rattikin at any time prior to CSL's delivery of a deed of the Property to Seller), this Contract shall terminate, all ▇▇▇▇▇▇▇ Money shall immediately be returned to Purchaser, Seller shall pay to Purchaser a sum of money equal to (i) the interest Purchaser actually paid to its lender on any funds borrowed by Purchaser (not to exceed $80,000,000 and actual closing costs) on or after the originally scheduled Closing Date to acquire the Property (hereafter, such sum (not to exceed $80,000,000 and the reasonable, actual closing costs) is referred to as the "Loan," whether or not such sum is part of a larger transaction between Purchaser and its lender), less any income received or credited to Purchaser on the Loan (Purchaser agreeing to take commercially reasonable steps to cause to be invested the Loan proceeds immediately upon receipt) (the "Interest Differential"), plus (ii) all actual sums paid by Purchaser in connection with obtaining the Loan and re-paying the Loan to the lender (collectively, the sums set forth in clauses (i) and (ii) are defined as the "Reimbursement"), and thereafter the parties shall have no further rights or obligations one to the other hereunder except those that specifically survive termination as set forth herein. In the event this transaction closes but Closing has been delayed solely due to the failure of CSL to deed the Property to Seller at or prior to the originally scheduled Closing Date, Purchaser shall receive a credit against the Purchase Price in the amount of the Interest Differential. In the event Purchaser is entitled to the Reimbursement or a credit against the Purchase Price in the amount of the Interest Differential, Purchaser shall deliver written evidence reasonably satisfactory to Seller to establish such amounts.

D.

Payment Obligation. In addition to the Basic Rent specified in this Lease, Tenant shall pay to Landlord as Additional Rent for the Premises, in each calendar year or partial calendar year during the term of this Lease, an amount equal to the Operating Expenses for such calendar year.

1.: Payment of Operating Expenses: Operating Expenses for the remainder of the calendar year after the Commencement Date and for each subsequent calendar year (or partial calendar year) shall be reasonably estimated by Landlord, and written notice thereof shall be given to Tenant at least thirty (30) days prior to the beginning of each calendar year, or as soon thereafter as is reasonably practical. For any such remainder of the calendar year after the Commencement Date, Tenant shall pay to Landlord each month, at the same time the Basic Rent is due, an amount equal to the amount of such estimated Additional Rent for the remainder of such calendar year divided by the number of months remaining in such year, and for each calendar year thereafter, Tenant shall pay to Landlord each month, at the same time

the Basic Rent is due, an amount equal to one-twelfth (¹/12) of the estimated annual Additional Rent due.

2.: Revisions in Estimated Additional Rent. If Operating Expenses increase or decrease during the calendar year, Landlord may revise the estimated Additional Rent during such year by giving Tenant written notice to that effect, and in the event Tenant vacates all or a portion of the Premises, then Landlord shall revise the estimated Additional Rent to reflect any decrease in such Additional Rent. Thereafter, Tenant shall pay to Landlord, in each of the remaining months of such year, an amount equal to the amount of such increase (or decrease, as appropriate) in the estimated Additional Rent divided by the number of months remaining in such year.
3.: Adjustments to Actual Additional Rent. Within ninety (90) days after the end of each calendar year, or as soon thereafter as is reasonably possible, Landlord shall prepare and deliver to Tenant a statement showing Tenant's actual Additional Rent for the previous calendar year (each such annual statement, an "Annual Statement"). Within thirty (30) days after receipt of the aforementioned statement, Tenant shall pay to Landlord, or Landlord shall credit against the next Additional Rent payment or payments due from Tenant, as the case may be, the difference between Tenant's actual Additional Rent for the preceding calendar year and the estimated Additional Rent paid by Tenant during such year. If, however, Landlord owes Tenant a credit pursuant to the preceding sentence and this Lease has expired or terminated prior to the date that Landlord makes the required credit, Landlord shall pay to Tenant the amount of the credit, provided, however, if at the time this Lease is terminated, Tenant owes any amounts to Landlord under the terms of this Lease (including damages), then Landlord may apply the credit against the amounts which Tenant owes. Notwithstanding the foregoing, if Landlord fails for any reason, other than as a result of the occurrence of an event of force majeure, to deliver to Tenant the Annual Statement by June 30 of the applicable year, then, until such Annual Statement is delivered, the amount of the installments of estimated Additional Rent shall revert to the amount of the installment of Additional Rent that was payable in the month of December for the year immediately preceding such applicable calendar year. If the installments of Additional Rent are reduced pursuant to the preceding sentence, such reduction shall in no way affect Tenant's obligation to pay the amount (if any) by which the actual Additional Rent (as evidenced by the Annual Statement, when delivered) for the applicable year exceeds the installments of estimated Additional Rent paid by Tenant during the applicable year.

E.

Rent.

1.: Rent Defined. The Basic Rent, the Additional Rent, and all other sums Tenant is required to pay hereunder are sometimes collectively referred to as, and shall constitute, "Rent."
2.: Rent Payable without Demand. Rent shall be paid by Tenant to Landlord when due, without prior demand therefor and without notice, deduction or set off, except as otherwise specifically provided herein, at such place as Landlord may designate in writing.
3.: Late Charges. In the event more than one (1) installment of Rent under this Lease in any calendar year shall not be paid when due, a "Late Charge" at an annual interest rate of ten percent (10%) of each dollar so overdue may be charged by Landlord, for the purpose of defraying Landlord's administrative and other expenses incident to the handling of such overdue payments. Landlord and Tenant agree that such late charge will fairly compensate Landlord for such administrative and other expenses upon which both parties are unable to determine precisely.

F.: Audit Rights. Landlord agrees to maintain complete and accurate records of all costs, expenses and disbursements which are incurred by Landlord, its employees, agents and/or contractors, with respect to Operating Expenses for the Project and the constituent components thereof. Tenant and/or its employees or a nationally recognized CPA firm, at Tenant's sole cost and expense and with no contingency fee, shall have the right to perform an audit of Landlord's books and records pertaining to Operating Expenses, subject, however, to the following conditions: (a) an audit may not be conducted for any calendar year preceding 2006, (b) no calendar year may be audited more than once, (c) Tenant shall have no right to audit any calendar year if the audit is to be commenced more than two (2) years after the end of such calendar year, (d) no such audit may be conducted unless Landlord receives at least thirty (30) days prior notice setting forth the proposed dates for the audit and the year or years for which the audit will be conducted, and (e) the activities of the auditor shall be conducted in an area designated by Landlord within the continental United States and then only during normal business hours. Landlord agrees to reimburse Tenant for the professional or accounting costs and expenses incurred by Tenant in connection with any such inspection and/or audit conducted by or for Tenant, but only if said inspection and/or audit shall prove that Operating Expenses for the period of time covered by such inspection and/or audit shall have been overstated by five percent (5%) or more. The right of Tenant to audit and any audit by Tenant of Landlord's books and records pertaining to Operating Expenses shall not affect the obligation of Tenant to pay, in accordance with the terms hereof, estimated Additional Rent subject, however, to Landlord's reimbursement and/or reconciliation obligations set forth herein. Tenant and its authorized representatives shall keep any such audit confidential and shall sign appropriate confidentiality agreements except as such disclosure is required by judicial proceedings or compliance with regulatory requirements or as necessary for Tenant's attorneys, accountants, employees and consultants in undertaking such audit and performing Tenant's usual business, but any disclosure of such audit to another tenant or sublessee in the Complex is prohibited.

If Landlord leases or subleases any portion of the Premises vacated by Tenant to a third party, the Additional Rent payable by Tenant on any remaining portion of the Premises leased but not occupied by Tenant (and not leased or subleased to a third party) shall continue to reflect the reduced level of services provided to such vacant space, notwithstanding the fact that a higher level of services may be provided to the space leased or subleased to the third party.

SECTION 5.02 SERVICES TO BE PROVIDED BY TENANT. Tenant shall, at its sole cost and expense, contract directly with one or more third parties for any services that Tenant shall require to monitor Tenant's telecommunication rooms/closets, vaults, safes and server rooms located in the Building (the "Secured Areas"). In addition, during the term of this Lease Tenant shall contract directly with an independent third party in order to provide security services for the Project (the "Security Services Contract"). The scope of such services that are in effect on the Effective Date and the qualifications of such independent third party are hereby deemed approved by Landlord. The cost of such Security Services Contract shall be borne solely by Tenant and shall not be included as part of the Operating Expenses. To the extent that such Security Services Contract is terminated or expires during the term of the Lease for any reason, then Landlord shall have the right to provide or cause such security services to be provided for the Project as Landlord deems necessary and appropriate and the cost thereof shall be included within the Operating Expenses.

SECTION 5.03 TENANT'S OBLIGATION. Tenant agrees to cooperate at all times with Landlord and to abide by all regulations and requirements which Landlord may reasonably prescribe (with advance notice to Tenant) for the use of the above utilities and services.

SECTION 5.04 SERVICE INTERRUPTION.

A.: No Liability for Failure to Provide Services Due to Certain Reasons. Landlord shall not be liable for, and Tenant shall not be entitled to, any abatement or reduction of Rent and, except as set forth in Section 5.04B below, any reimbursement to Tenant by Landlord for Tenant's costs, by reason of Landlord's failure to maintain temperature or electrical constancy levels or to furnish any of the foregoing services when such failure is caused by accident, breakage, repairs, strikes, lockouts or other labor disturbance or labor dispute of any character, governmental regulation, moratorium or other governmental action, inability by exercise of reasonable diligence to obtain electricity, water or fuel, or by any other cause beyond Landlord's reasonable control, nor shall any such failure, stoppage or interruption of any such service be construed as an eviction of Tenant, or relieve Tenant from the obligation to perform any covenant or agreement herein, and, except as otherwise expressly provided in this Lease, Landlord shall not be liable for damage to persons or property, or in default hereunder, as a result of such failure, stoppage or interruption of any such service. If the correction of any failure, stoppage or interruption of such services is within the control of Landlord, Landlord shall use reasonable diligence to resume service promptly. If the interruption

of service is within the control of a utility or other provider of such service and not Landlord, Landlord will use reasonable efforts to cause the appropriate utility or other provider to restore promptly the delivery of such service(s), but shall not be under an obligation to expend funds.

B.: Provision of Interim Services in Connection with Failure of Certain Services. If there is a failure to provide electricity, HVAC Services, water and/or sewer service to the Premises that makes a material portion of the Premises Untenantable (as hereinafter defined) and such failure continues for a period of three (3) consecutive Business Days, (i) Tenant may undertake to provide interim services to the Premises by temporary generators, temporary chillers, port-o-lets and/or bottled water (provided Tenant may undertake such measures prior to the third consecutive business day, but Landlord's obligation to reimburse Tenant as set forth in the following subclause (iii) shall not apply to any such costs incurred by Tenant prior to such third consecutive Business Day), (ii) Landlord shall cooperate in the provision of such temporary services, and (iii) Landlord will, within thirty (30) days after receipt of an invoice, reimburse Tenant for Tenant's reasonable costs incurred in supplying and/or operating such temporary generators, temporary chillers, port-o-lets and/or bottled water. Tenant may not, however, assume control of repairs necessary to provide a long-term repair of the problem.
C.: Untenantability. If the Premises or a material portion thereof becomes Untenantable as a result of the failure of HVAC Services, electrical services, water services or sewer services and the Premises remain Untenantable for a period of three (3) consecutive Business Days, Tenant shall be entitled to an equitable abatement of Basic Rent and Additional Rent, which abatement (i) shall be retroactive to the first Business Day that any material portion of the Premises became Untenantable as a result of the failure of any such services and (ii) shall continue until such services are restored to the Premises or applicable material portion of the Premises, as the case may be. The term "Untenantable" shall mean the condition whereby Tenant's use or enjoyment of the Premises or such portion thereof is disrupted to the degree that Tenant's employees cannot reasonably use such space for the uses permitted in this Lease. Notwithstanding the provisions of this paragraph C or paragraph B preceding, if the Premises or portion thereof are made Untenantable by Landlord's gross negligence or willful misconduct, the equitable abatement will commence on the first day that the Premises or portion thereof is Untenantable.
D.: Consecutive Day Period. For purposes of this Lease, a required period of "consecutive Business Days" and a required period of "consecutive days" shall only be interrupted by the re-establishment of the service for at least six (6) hours during Normal Business Hours on a Business Day.

SECTION 5.05 MANDATORY REQUIREMENTS.

A.: Compliance with Laws and Controls. In the event any governmental entity promulgates or revises any Law and or imposes controls relating to the use or conservation of energy, water, gas, light, or electricity or the reduction of emissions or the provision of any other utility or service provided with respect to this Lease, Landlord shall comply with such Laws and controls. In the event that any governmental entity establishes any guidelines relating to the use or conservation of energy, water, gas, light, electricity, or any other utility service or the reduction of emissions, Landlord may comply, but shall not be required to comply, with all or any of such guidelines. Any improvements to or alterations made by Landlord to the Building or the Project and any revisions to or modifications of existing equipment and machinery made by Landlord, as well as the acquisition of new equipment and machinery by Landlord in order to comply with such Laws, controls and guidelines shall be deemed to be Cost Saving Capital Improvements, except to the extent the costs thereof may be expensed under GAAP, in which event such costs shall be treated as Operating Expenses.

B.: Untenantability. If the Premises or a material portion thereof are rendered Untenantable for more than ten (10) consecutive days because of Landlord's compliance or attempt to comply with the Law, controls and/or guidelines described in paragraph A preceding, Tenant's sole remedy shall be an equitable abatement of Basic Rent and Additional Rent for the period of time during which the Premises or material portion thereof are (is) rendered Untenantable. Landlord agrees to use reasonable efforts, to the extent practicable, to undertake compliance with such Laws, controls and guidelines hereunder in a manner reasonably calculated to avoid interference with Tenant's use and occupancy of the Premises. Nothing herein shall be deemed to apply to any casualty loss.

A.: Casualty Damage that can be Completed within 180-Days. If the Base Building, Base Building Systems, Parking Facilities or portion of the Project that provides access to or is necessary for the use of the Building is/are damaged by fire or other insured casualty (the repairs needed to correct such damage, the "Landlord Required Repairs") and Landlord reasonably determines that the Landlord Required Repairs can be completed within one hundred eighty (180) days after Landlord becomes aware of the damage causing the Landlord Required Repairs, then Landlord shall commence and pursue the completion of the Landlord Required Repairs with reasonable diligence, subject to the conditions that Landlord shall have received all insurance proceeds under the policies described in Section 7.04A2 and consent from its lender to use the insurance proceeds to make the Landlord Required Repairs. Landlord agrees to use reasonable and diligent efforts to collect the insurance proceeds payable in respect of the Landlord Required Repairs under the policy of insurance described under Section 7.04A2 Landlord shall also use reasonable and diligent efforts to obtain the consent of its Lenders to allow use of the insurance proceeds for the completion of the Landlord Required Repairs.
B.: Required Repairs that will not be Completed within 180-Days. If Landlord reasonably determines that the Landlord Required Repairs cannot be completed within one hundred eighty (180) days after Landlord becomes aware of the occurrence of the damage causing the Landlord Required Repairs, then Landlord shall so notify Tenant and (i) Landlord or Tenant may terminate this Lease by delivering written notice to the other a termination notice (a "Termination Notice") within thirty (30) days after Landlord becomes aware of the casualty damage giving rise to the Landlord Required Repairs, subject however, to the condition that Landlord, within such thirty (30) day

period, shall have the right to deliver written notice to Tenant (the "Non-Termination Notice") stating that Landlord will promptly commence the Landlord Required Repairs and diligently pursue the completion thereof after (a) the proceeds under the policies described in Section 7.04A2 are delivered or made available to Landlord for the purpose of making the Landlord Required Repairs and (b) Landlord obtains the consent of its lenders to use the insurance proceeds for the completion of the Landlord Required Repairs. If Landlord timely delivers to Tenant the Non-Termination Notice, (1) this Lease shall remain in full force and effect, (2) any Termination Notice delivered within the required 30-day period shall have no force or effect, and (3) Landlord will commence and pursue the completion of the Landlord Required Repairs with reasonable diligence, after receipt of the insurance proceeds and its lenders' consent as described above. If Landlord fails to deliver to Tenant a Non-Termination Notice within the required 30-day period and either Landlord or Tenant forwards a Termination Notice to the other within the required 30-day Period, then this Lease shall terminate on the termination date set forth in the applicable Termination Notice, which date shall not be less than thirty (30) days nor more than sixty (60) days after the non-terminating party receives the terminating party's Termination Notice. If each of Landlord and Tenant deliver to the other a Termination Notice within the required 30-day period, the effective Termination Notice will be that which is first received.

Untenantability. If (a) any material part of the Premises is rendered Untenantable by fire or other casualty, (b) such Untenantable condition continues for more than three (3) consecutive days, and (c) this Lease is not terminated as a result of the fire or other casualty pursuant to paragraph B preceding, then the Basic Rent and Additional Rent shall be equitably abated from the date such part of the Premises became Untenantable until the date that such part of the Premises is no longer Untenantable. Notwithstanding the foregoing, there shall be no abatement of Rent if (i) Landlord provides to Tenant other space in the Complex in substitution for the portions of the Premises that are Untenantable and that is reasonably suited, in Tenant's reasonable judgment, for Tenant to temporarily conduct its business within the alternate space as such business was conducted in the portions of the Premises that are Untenantable and (ii) Landlord pays all reasonable direct out-of-pocket, but not consequential, costs for moving Tenant into and out of the alternate space, including, without limitation, installation of cabling necessary to operate Tenant's business within the alternate space.

D.

Certain Tenant Responsibilities.

Notwithstanding paragraphs A, B, and C of this Section, if this Lease is not terminated pursuant to paragraph B of this Section, Tenant shall promptly commence and thereafter diligently pursue the completion of the repair and/or replacement of all portions of the Premises that are damaged by the fire or other casualty, including the non-Base Building installations above the ceiling and any sub-floors, Tenant's Alterations, any other leasehold improvements which are constructed by Tenant in the Premises pursuant to this Lease and Tenant's FF&E (the "Tenant Required Repairs"), with the proceeds from the insurance Tenant is required to maintain under Section 7.03A3. Tenant shall coordinate the completion of the Tenant Required Repairs with Landlord's completion of Landlord's Required Repairs. Landlord will cooperate with Tenant in the performance of the Tenant Required Repairs.

the Premises, and in either event, if Tenant does not repair or reconstruct the Premises in accordance with the foregoing, then Tenant shall promptly tender to Landlord the proceeds of Tenant's insurance maintained under Section 7.03A3.

(c): Limitations on Landlord Responsibilities. Landlord shall have no obligation to repair any damage to the Premises or Tenant's FF&E installed or located in or about the Premises, unless caused by Landlord's gross negligence or willful misconduct and then only if Tenant has not waived its Claims with respect to such damage under Section 7.05 below. If Landlord is responsible for repairing any damage to the Premises or Tenant's FF&E pursuant to the preceding sentence, Tenant will seek to collect any insurance proceeds payable as a result of any such damage or repair and such proceeds shall be delivered to Landlord to effect such repairs.

E.: Effect of Termination. In the event Landlord or Tenant terminates this Lease pursuant to the terms of this Section 7.01, this Lease and the estate and interest of the Tenant in the Premises shall terminate and expire on the date specified in such party's notice of termination and the Basic Rent and Additional Rent payable hereunder shall be prorated as of such date, subject to rent abatement, if any, to the extent provided in this Section 7.01 and Landlord and Tenant shall be relieved from any further obligations hereunder, save and except for obligations and liabilities existing as of the date of termination and any provisions of this Lease which expressly survive the termination of this Lease, as well as any provisions of this Lease, which by their nature, are performable after the termination of this Lease.

If Tenant is responsible for repairing any damage to the Building pursuant to the preceding sentence, Landlord will seek to collect any insurance proceeds payable under its insurance policies as a result of any such damage and such proceeds shall be made available to Tenant to effect such repairs. Moreover, Tenant shall not be entitled to abatement of Basic Rent and Additional Rent under paragraph C of this Section if any Landlord Required Repairs or Tenant Required Repairs are the result of the gross negligence or willful misconduct of Tenant or any of its successors, assigns or subtenants or their respective officers, employees, representatives, agents, contractors, or invitees.
G.: Landlord Not Liable for Lost Profits/Lost Revenues, etc. Landlord shall not be liable to Tenant, its successors and assigns, for any loss of business, revenue or profits, inconvenience or annoyance or any other loss whatsoever arising from any casualty damage to, or repair or restoration of, any portion of the Premises, the Building or the Project as a result of any damage from fire or other casualty or defect in the Premises, the Base Building (including Building Systems) or actions of other tenants or subtenants in the Project or actions or inactions of any utility or other event beyond Landlord's reasonable control. Tenant shall secure insurance for itself for any such loss of revenue, profits, damage to its business or the like as required by Section 7.03A4 below and Tenant agrees to look solely to the insurance proceeds from such policy, which it obtains or is required to obtain, for such losses, if any.

Tenant shall, at least ten (10) days prior to the expiration of any such policy, furnish Landlord with certificates of renewal or certificates of replacement policies which fully comply with the requirements of this Lease, or Landlord, after written notice to Tenant and an opportunity to cure such default as provided in Section 13.01B, may order such insurance and charge the cost thereof to Tenant, which amount shall be payable by Tenant upon written demand.
F.: Blanket Insurance/Self Insurance. Tenant, but not any assignee or sublessee of Tenant, except for an assignee which is Tenant's Parent Company or Affiliate (as defined in Section 11.02A below) with a financial strength equal to or better than tenant's financial strength, shall have the option, (a) to maintain and provide or maintain any insurance required by this Lease under blanket insurance policies maintained by Tenant or (b) provide and maintain all required insurance through such alternative risk management programs as Tenant may provide from time to time (such types of alternative risk management programs being herein collectively and severally referred to as "self insurance"), provided (a) such self insurance does not thereby decrease the insurance coverage or limits set forth in paragraph A of this Section, (b) adequate reserves are maintained to cover all self-insured risks, and (c) the self insurance program complies with all applicable Laws. If Tenant elects to self insure any of the coverages required under paragraph A of this Section, then, prior to undertaking such self-insurance program, Tenant shall deliver to Landlord a written notice of such undertaking which notice shall (1) state the limits of the self-insurance program and individual coverages, (2) state the reserves maintained with respect to the self insurance, (3) be accompanied by reasonable evidence that the self insurance program complies with applicable Laws, (4) state the amount of any excess coverage insured by third parties and the identity of such third party insurers, and (5) state that Tenant affirms its obligations to Landlord to act as an insurer under the coverages required under paragraph A of this Section. Tenant expressly waives any right of recovery against Landlord to the full extent of any such self insurance program maintained by Tenant just as if Tenant had acquired such coverage from a third party insurance carrier. Each of the parties agree that the foregoing release and waiver applies to any deductibles or self-insured retentions or the like maintained by such party. In addition to the foregoing, any self insurance shall be deemed to contain all of the terms and conditions and satisfy all the requirements applicable to such insurance as required in this section of this Lease and shall be deemed to provide all coverage provided by the policies described in paragraph A of this Section, including without limitation the waiver of subrogation contained in Section 7.05 below and the waiver of subrogation requirements in paragraph C of this Section. If self insurance is provided, Tenant will provide certificates of insurance satisfying the requirements of paragraph D of this Section (which certificates shall be on ACCORD Form 27). If Tenant elects to self insure, then, with respect to any claims that may result from incidents occurring during the term of this Lease, such self insurance obligation shall survive the expiration or earlier termination of this Lease to the same extent as the required insurance would survive same.

SECTION 7.04 LANDLORD'S INSURANCE.

A.

Required Insurance. Landlord shall at all times during the term of this Lease carry and maintain the following insurance:

1.: Commercial General Liability. Commercial general liability insurance adequate to protect Landlord against liability for injury to or death of any person or damage in connection with the Project.
2.: Casualty Insurance. Casualty insurance policy that covers the Base Building of each structure on the Project (excluding property required to be insured by Tenant or other tenants) providing protection against all perils included within the classification of "All Risks", together with insurance against sprinkler damage, vandalism and malicious mischief, and such other risks as Landlord may from time to time determine and with any reasonable deductibles as Landlord may from time to time determine. Such All Risks policy shall be issued for 100% of the replacement costs of the Building. Landlord shall carry such casualty insurance for its equipment as it deems necessary or appropriate.
3.: Rent Loss Insurance. Landlord may carry rental loss insurance in such amounts as it deems necessary or appropriate from time to time.

B.

Additional Insurance. Landlord shall have the right to carry any and all insurance required by its lenders or any other insurance that a landlord or owner of commercial office buildings and data centers would generally carry or have a right to carry.

C.

Blanket Insurance. Any insurance provided for in this Section 7.04 may be effected by a policy or policies of blanket insurance, covering additional items or locations or assureds, provided that the requirements of this Section are otherwise satisfied.

SECTION 7.05 WAIVER OF SUBROGATION. To the extent such waivers are obtainable from third-party insurance carriers, Landlord and Tenant each hereby waive their respective rights of recovery against the other for injury or loss due to hazards covered by insurance, including self-insurance, either carried by or required in this Lease to be carried by such party, and each agree to obtain a waiver of subrogation from its third-party insurance carriers, and each releases the other from any damage to the property of the other or under its control, including in such release each such parties' officers, directors, and employees and each parties' interest in the Project by fire or other casualty (including liability for loss of rent or loss of profits or other loss) to the extent such damage or loss is insured against under a policy or policies of insurance, including any self-insured retentions, deductibles, "captive" insurance carriers, or other self-insurance maintained by such party, whether or not such damage may be attributable to the negligence or act of such party(ies) or its/their respective agents, invitees, contractors, servants, or employees. Such waiver shall in no way be construed or interpreted to limit or restrict any indemnity or other waiver made by any party under the terms of this Lease to the extent such loss is not required to be insured against under this Lease.

ARTICLE 8

CONDEMNATION

SECTION 8.01 LANDLORD'S OPTION TO TERMINATE. In the event the Building or Parking Facilities, or any portion thereof necessary, in the opinion of Landlord, to the continued efficient and/or economically feasible use of the Building shall be taken or condemned, either temporarily or permanently, in whole or in part for public purposes, or sold to a condemning authority under threat of condemnation to prevent taking, then the term of this Lease may, at the sole option of the Landlord, forthwith cease and terminate.

SECTION 8.02 TENANT'S RIGHT TO TERMINATE. If 25% or more of the Premises are condemned or transferred in lieu of condemnation to an entity with the power of condemnation, then Tenant shall have the right to terminate this Lease upon written notice delivered to Landlord by Tenant within five (5) business days after title to such space has been transferred to the condemning authority; otherwise, this right of termination shall expire without further action by any party.

SECTION 8.03 EFFECT ON RENT. In the event of termination of this Lease, all Rent due from Tenant to Landlord shall be abated and terminated for the remaining Term of the Lease after the date of termination of the Lease. If Landlord and Tenant, if applicable, elect not to terminate this Lease, then Landlord shall grant a reasonable reduction in Rent to Tenant to reflect any reduction in the space constituting the Premises and/or any reduction in Tenant's parking rights in the Parking Facilities as a result of such partial condemnation.

SECTION 8.04 AWARD. Under all circumstances and without regard to whether or not the Lease is terminated, the Landlord shall receive the entire award for land, buildings, and improvements. Tenant hereby expressly assigns to Landlord any and all right, title, and interest of Tenant now or hereafter arising in and to any such award for the land, buildings, and such other improvements as are paid for by Landlord. Tenant shall have the right to recover from such authority, but not from Landlord, any compensation as may be awarded to Tenant on account of moving and relocation expenses and depreciation to and removal of Tenant's personal property.

ARTICLE 9

LIENS

Tenant shall keep the Premises free from any liens arising out of any work performed, materials furnished, or obligations incurred by or for Tenant. In the event that Tenant shall not, within twenty (20) days following the imposition of any such lien, cause the same to be released of record by payment or posting of a proper bond, Landlord shall have, in addition to all other remedies provided herein and by law, the right but not the obligation, to cause the same to be released by such means as it shall deem proper, including payment of or defense against the claim giving rise to such lien. All sums paid by Landlord and all expenses incurred by it in connection therewith shall create automatically an obligation of Tenant to pay, on written demand, an equivalent amount, plus interest thereon as provided in Section 16.12 herein, as Rent. No work that Landlord permits Tenant to perform in the Premises shall be deemed to be for the use and benefit of Landlord so that no mechanics or other lien shall be allowed against the estate of Landlord by reason of its consent to such work. Landlord shall have the right to post notices that it is not responsible for payment for any such work.

ARTICLE 10

TAXES ON TENANT'S PROPERTY

If billed directly to Tenant, Tenant shall, as and when required by Law, pay to the applicable taxing authority and, if billed to Landlord, Tenant shall, within thirty (30) days after receipt of written notice from Landlord, pay to Landlord, any and all taxes and assessments levied against any personal property or trade or other fixtures placed by Tenant in or about the Premises, including any additional real estate taxes or assessments which may be levied against the Building by reason of installation of Tenant Alterations.

ARTICLE 11

SUBLETTING AND ASSIGNING

SECTION 11.01 GENERAL PROHIBITION ON SUBLEASING AND ASSIGNMENT. Except to a Parent, Affiliate or Subsidiary of Tenant (as each such term is defined below), Tenant shall not assign

this Lease, or allow it to be assigned, in whole or in part, by operation of law or otherwise or mortgage or pledge the same, or sublet the Premises, or any part thereof, without the prior, written consent of Landlord.

SECTION 11.02 PERMITTED ASSIGNMENTS AND SUBLEASES AND CONDITIONS TO APPROVALS.

A.

Permitted Sublease to an Affiliate, Parent, or Subsidiary.

1.: Assignment to Affiliate, Parent or Subsidiary. Tenant may sublease or assign its rights under this Lease to a Parent Company, an Affiliate, or a Subsidiary without Landlord's prior, written consent, but Tenant shall remain primarily liable for payment of all Rent and the performance of all Tenant's obligations under this Lease.
2.: Definitions. A "Parent Company" of Tenant is a corporation, which directly owns at least fifty-one percent (51%) of the outstanding common voting stock of Tenant. An "Affiliate" of Tenant is any corporation fifty-one percent (51%) or more of the stock of which is owned, directly or indirectly, by Tenant or Tenant's parent company. A "Subsidiary" of Tenant is any corporation fifty-one percent (51%) or more of which is owned by Tenant.
3.: Required Notice. If Tenant desires to sublet or assign all or any part of the Premises to a Subsidiary, Affiliate or Parent Company, it shall so notify Landlord at least ten (10) business days in advance of the date on which Tenant desires to make such assignment or sublease and shall provide Landlord with such information as Landlord may reasonably request concerning the proposed sublessee or assignee, including the identity of the proposed sublessee or assignee and information which establishes the proposed sublessee or assignee as a Parent Company, Affiliate, or Subsidiary of Tenant.

B.

Conditions to Approval for Assignment to Entity other than a Parent Company, Affiliate, or Subsidiary.

1.

Required Notice and Information. Except as provided in Section 11.02A above, if the Tenant desires to assign or sublet all or any part of the Premises to a third party, it shall so notify Landlord that Tenant desires to make such assignment or sublease and shall provide Landlord with a copy of the proposed assignment or sublease, and such information as Landlord might reasonably request concerning the proposed sublessee or assignee to allow Landlord to make informed judgments as to the financial condition, reputation, proposed use (and no telemarketing use shall be permitted), operations, and general desirability of the proposed subtenant(s) or assignee(s).

2.

Landlord's Options. Within twenty (20) days after Landlord's receipt of Tenant's proposed assignment or sublease, and all requested information concerning the proposed subtenant(s) or assignee(s), Landlord shall, in its sole discretion, have the option to:

(a): Consent. Consent to the proposed assignment or sublease, in which event (i) without limiting the assignee's or subtenant's responsibilities and obligations under the applicable assignment, Tenant shall remain primarily liable for payment of all Rent and the performance of all Tenant's obligations under this Lease and (ii) if the rent due and payable by any assignee or sublessee under any such permitted assignment or sublease (grossed up by any bonus, allowance or other payments or credits allowed to the assignee or subtenant and any other consideration paid by Tenant to or on behalf of the assignee or subtenant and reduced by the reasonable commissions paid by Tenant to a broker to secure the subtenant or assignee, reasonable legal fees incurred by Tenant to negotiate the assignment or sublease agreement and the actual dollars paid by Tenant to retrofit the Premises for use by the assignee or subtenant) exceeds the Rent payable under the Lease for such space, Tenant shall pay to Landlord fifty percent (50%) of such excess rent and

other excess consideration within five (5) business days following receipt thereof by Tenant, but Landlord shall not be entitled to participate in any consideration received by Tenant for the sale of its assets (other than consideration for the Lease). Tenant may, in connection with any such assignment or sublease, transfer title to personal property located in the Premises and any consideration paid by the assignee or subtenant for such personal property shall not be considered as part of the proceeds of the assignment or sublease so long as the consideration paid does not result in a reduction of basic rent under the sublease or the rent or payment received in connection with an assignment. The foregoing sharing arrangement will not apply to a spin-off of any portion of Tenant's business; provided, however, if there is any actual assignment or sublease executed in connection with any such spin-off, the sharing arrangement set forth above shall apply.

(b): Refuse to Consent. Refuse its consent to the proposed assignment or sublease.

3.: Deemed Consent. Landlord's consent to the third party assignment shall be deemed granted if Landlord does not respond to Tenant's request within twenty (20) days after Landlord's receipt of all information and items required under Section 11.02B1 above.

SECTION 11.03 CONTINUING LIABILITY. No consent by Landlord to any assignment or sublease by Tenant shall relieve Tenant of any obligation to be performed by Tenant under this Lease, whether arising before or after the assignment or sublease. The consent by Landlord to any assignment or sublease shall not relieve Tenant from the obligation to obtain Landlord's express written consent to any other assignment or sublease. Any assignment or sublease, which is not in compliance with this Section 11, shall be voidable and, at the option of Landlord, shall constitute a material default by Tenant under this Lease. The acceptance of rent by Landlord from a proposed assignee or sublessee shall not constitute the consent to such assignment or sublease by Landlord.

SECTION 11.04 SALE BY TENANT. Any sale or other transfer, including by consolidation, merger or reorganization, of a majority of the voting stock of Tenant, if Tenant is a corporation, or any sale or other transfer of a majority in interest (whether of profits, losses, capital, or voting power) or a majority of the persons composing the managers of the partnership, if Tenant is a partnership, shall not be an assignment for purposes of this Article 11, if the leasehold estate of Tenant under this Lease constitutes all or substantially all of the assets of Tenant as of the date of the sale or other transfer.

SECTION 11.05 TENANT'S FAILURE TO OCCUPY. If at any time during the term of this Lease, Tenant or an affiliate of Tenant is not occupying the Building (or a portion thereof), or has advised Landlord that it does not intend to occupy the Building (or a portion thereof) in the future, Tenant shall promptly provide Landlord with written notice of such decision and Landlord will thereafter have the right to market the Building (or applicable portion thereof) for lease or sublease and, if successful, enter into a sublease or lease, as applicable. Tenant shall be permitted to reoccupy any portion of the Premises once it has vacated such space in the Building provided Tenant is not then in default under this Lease and Landlord is not then conducting bona fide negotiations with a third party to lease or sublease such vacated space. If at any time after the first eighteen (18) months of the term Tenant vacates any portion of the Premises, Tenant shall use its best efforts to thereafter promptly consolidate its remaining employees in the Building into that certain minimum number of floors, or portion thereof, in the remaining portion of the Premises. In addition, if Tenant vacates any portion of the Premises at any time after the first eighteen (18) months of the term, it shall use its best efforts to surrender that portion of the Premises in the largest and most contiguous block of space as is commercially practicable so that Landlord can market such vacated space. If Tenant vacates any portion of the Premises during the first eighteen (18) months of the term, Landlord shall be entitled to request that Tenant use its best efforts to promptly consolidate its remaining employees in the Building into that certain minimum number of floors, or portion thereof, in the remaining portion of the Premises at the sole cost and expense of Landlord, but Tenant shall not be obligated to effect such consolidation. If

Tenant occupies less than one-half of the Building at any time after the first eighteen (18) months of the term, then Landlord shall have the right to enter into one or more leases or subleases for that portion of the Premises that Tenant is then occupying and upon forty-five (45) days advance notice from Landlord, Tenant shall thereafter promptly vacate the Premises. If Tenant has previously vacated any portion of the Premises and then subsequently reoccupies such vacated space in accordance with the second sentence in this Section 11.05, Tenant's subsequent reoccupancy of such previously vacated space shall not be included for purposes of calculating the portion of the Building that Tenant is then occupying. If Landlord elects to enter into a direct lease for the Premises (or any portion thereof), then (i) Landlord shall have the right to terminate this Lease (or applicable portion thereof), in which event Tenant will deliver the Premises (or applicable portion thereof) to Landlord in the required condition under Section 1.03 of this Lease within forty-five (45) days after receiving a written notice from Landlord stating that it is terminating the Lease (or applicable portion thereof), (ii) Tenant will promptly enter into a termination agreement, modification agreement or lease amendment, as appropriate, in such form as is required by Landlord which termination will be effective on the day prior to the date the New Tenant occupies its leasehold space in the Building for the purpose of conducting its business with the general public (the "Termination Date"), provided that such termination agreement, modification agreement or lease amendment, as appropriate, shall not increase Tenant's obligations under the Lease (or applicable portion thereof) or impose any liability on Tenant for obligations under this Lease, save and except for those obligations which survive the termination of this Lease (or applicable portion thereof) by express provision or by the nature of the applicable provision or obligation, and (iii) such termination agreement, modification agreement or lease amendment, as appropriate, shall provide that Tenant shall pay Landlord within thirty (30) days of Tenant's receipt of an invoice therefor (which invoice shall not be sent to Tenant until the Termination Date) that certain amount equal to the lesser of (x) the sum of (a) the tenant improvement allowance or any other allowance that Landlord pays to any tenant (the "New Tenant") that occupies the Building (or any portion thereof) under a direct lease with Landlord; (b) any brokerage, consulting or finder's fees that Landlord pays to any real estate broker, agent, consultant or finder that represents Landlord and/or such New Tenant; (c) amounts expended to improve the Building in connection with the lease to New Tenant; and (d) Landlord's legal fees to negotiate such direct lease with New Tenant; (y) $58.00 per square foot of the Premises (or applicable portion thereof), and (z) all Basic Rent payments for the Premises (or applicable portion thereof) which remain due and owing from the Termination Date through the expiration of the term of the Lease discounted at a rate of six percent (6%) per annum (discounted monthly) to the Termination Date and adjusted for any amounts Tenant has paid in advance to Landlord, if any. If Landlord elects to enter into a sublease, Tenant agrees to (a) accept Landlord's sublessee, (b) provide an estoppel certificate to the proposed subtenant and Landlord setting forth such statements as are reasonably required by Landlord or the proposed subtenant, provided, however, Tenant shall not be obligated to provide any statements to Landlord or the proposed subtenant other than those statements that Tenant is required to deliver to Landlord under the provisions of Section 16.01 of this Lease, and (c) promptly enter into the form of sublease negotiated by Landlord and the proposed subtenant, provided that such sublease shall not increase Tenant's liability under this Lease or bind Tenant to any covenants or conditions not contained in this Lease and such sublease shall provide, in relevant part, that Tenant shall receive that portion of the Average Sublease Rent (as defined below) which exceeds an amount equal to the lesser of (x) the sum of (i) the tenant improvement allowance or any other allowance that Landlord pays to such subtenant, (ii) any brokerage, consulting or finder's fee that Landlord pays to any real estate broker, consultant, agent or finder that represents Landlord and/or such subtenant; (iii) amounts expended to improve the Building in connection with the sublease to subtenant; and (iv) Landlord's legal fees to negotiate such sublease with the subtenant; or (y) $58.00 per square foot of the Premises (or applicable portion thereof) (any such amount payable to Tenant, the "Excess Sublease Rent") until and to the extent that the Excess Sublease Rent exceeds the amount of Basic Rent then being paid by Tenant, provided Landlord has first recovered all of its costs under subsection (x) above, after which time Landlord and

Tenant shall each receive one-half (¹/2) of the amount by which the Average Sublease Rent exceeds the Basic Rent then being paid by Tenant (the "Increased Basic Rent"). Tenant's pro rata share of the Operating Expenses shall terminate as to the portion of the Premises subleased upon the date when such subtenant occupies the subleased Premises for the purpose of conducting its business with the general public. As used herein, "Average Sublease Rent" shall mean the weighted average of the Basic Rent payable by a subtenant to Landlord over the entire term of such subtenant's lease obligation, including Basic Rent payable by the subtenant under the sublease during the remaining term of the Lease and Basic Rent payable by subtenant during the primary term (but not any renewal or extension term) of any direct lease with Landlord which commences immediately upon expiration of the sublease (and the Lease term) and which is documented in conjunction with the sublease. Any amounts of Excess Sublease Rent or of Tenant's share of Increased Basic Rent due to Tenant shall be payable monthly by Landlord within fifteen (15) days after monthly Basic Rent payments from the subtenant are received by Landlord. If Landlord locates a prospective subtenant for a portion of the Premises and enters into a sublease with such prospective subtenant, then Tenant will only be obligated to pay Landlord the Basic Rent Tenant is then paying under this Lease for the remainder of the term of this Lease (plus the Additional Rent on any portion of the Premises not subleased as provided under Section 5.01 E.), Tenant shall not be obligated for any actions or failure to act by such subtenant or damages to the Premises incurred by Landlord which result from, arise out of or are caused by such subtenant, and Tenant's obligations to pay any other sums or owe any other duty to Landlord under the Lease for the portion of the Premises which is then being subleased shall thereafter terminate. In any event, Tenant will cooperate with Landlord in its efforts to secure a new tenant or subtenant for the Building, including signing documents not identified above which are reasonably necessary to accommodate such subleasing or leasing. Tenant acknowledges and agrees that once Landlord enters into a direct lease with New Tenant and/or a sublease with any sublessee, Landlord shall have the right to immediately thereafter commence and complete construction of the New Tenant's or sublessee's leasehold premises and that such construction shall not constitute a breach of Section 4.05 or any other provision of this Lease by Landlord.

SECTION 11.06 ASSUMED LIABILITIES. Each assignee, sublessee, and transferee (including but not limited to an assignee by assignment made pursuant to the provisions of Title 11 U.S.C. Section 101 et seq. as amended and in effect from time to time), other than Landlord, shall assume all obligations of Tenant under this Lease (including without limitation, those contained in this Section 11 on subletting, assignment, transfer, hypothecation, sale, and encumbrance), and shall be and remain liable jointly and severally with Tenant for the payment of all Rent and for the performance of all the terms, covenants, conditions, and agreements herein contained on Tenant's part to be performed for the term of this Lease. No assignment shall be binding on Landlord unless the assignee or Tenant shall deliver to Landlord a counterpart of the assignment satisfactory in substance and form to Landlord, consistent with the requirements of this Section 11.06, but the failure or refusal of the assignee to execute such instrument of assumption shall not release or discharge the assignee from its liability as set forth above.

SECTION 11.07 BANKRUPTCY OF TENANT. If this Lease is assigned to any person or entity pursuant to the provisions of the Federal Bankruptcy Code, Title 11 U.S.C. Section 101, et seq., as subsequently amended (the "Bankruptcy Code"), any and all monies or other considerations payable or otherwise to be delivered in connection with such assignment will be paid or delivered to Landlord (which shall include the cure of any existing monetary defaults by payment of same to Landlord and the cure of any non-monetary defaults by performance within ten (10) business days of the assumption of this Lease by Assignee), will be and remain the exclusive property of Landlord and will not constitute property of Tenant within the meaning of the Bankruptcy Code. Any and all monies or other considerations constituting Landlord's property under the preceding sentence not paid or delivered to Landlord will be held in trust for the benefit of Landlord and be promptly paid to or turned over to Landlord. For purposes of Section 365(f) (2) of the Bankruptcy Code "adequate assurances of future

performance" will include, but not be limited to, net worth and credit-worthiness equal to that of Tenant on the Commencement Date of this Lease, the deposit of a sum equal to three (3) months' Basic Rent and then applicable Additional Rent as a Security Deposit and the promise to cure all non-monetary defaults within sixty (60) days after there has been an order for relief under applicable bankruptcy law. Any person or entity to which this Lease is assigned pursuant to the provisions of the Bankruptcy Code, will be deemed without further act or deed to have assumed all of the obligations arising under this Lease on and after the date of such assignment. Any such assignee will upon demand execute and deliver to Landlord an instrument confirming such assumption.

SECTION 11.08 BANKRUPTCY OF ASSIGNEE. If Tenant assigns this Lease to any party and such party or its successors or representatives causes termination or rejection of this Lease pursuant to applicable bankruptcy law, then, notwithstanding any such termination or rejection, Tenant (A) shall remain fully liable for the performance of all covenants, agreements, terms, provisions and conditions contained in this Lease, as though the assignment never occurred and (B) shall, without in any way limiting the foregoing, in writing ratify the terms of this Lease, as same existed immediately prior to the termination or rejection.

ARTICLE 12

SECTION 12.01 SALE OF THE PROJECT. Landlord has the unrestricted right to sell, transfer or assign its rights in the Building, the Project, the Complex, this Lease, or any portion of the foregoing without Tenant's authority or approval. In the event of a sale or conveyance by Landlord of the Project and/or the Building, the same shall operate to release Landlord from any and all liability and obligations under this Lease arising after the date of such sale to the extent such liability and obligations are transferred to a third party. Tenant's right to quiet possession of the Premises shall not be disturbed so long as Tenant shall pay the Rent and observe and perform all of the provisions of this Lease to be observed and performed by Tenant, unless this Lease is terminated pursuant to specific provisions relating thereto or contained herein.

Tenant agrees that it will execute and deliver to the holder of each such lien, mortgage or deed of trust the SNDA in the form of Exhibit J attached hereto or such other commercially reasonable form required by any such holder. Tenant also agrees that any mortgagee or trustee may elect to have this Lease prior to any lien of its mortgage or deed of trust, and in the event of such election and upon notification by such mortgagee or trustee to Tenant to that effect, this Lease shall be deemed prior to said mortgage or deed of trust, whether this Lease is dated prior to or subsequent to the date of said mortgage or trust deed.

B.: Sale or Assignment of Interest in Premises. Tenant shall, in the event of the sale or assignment of Landlord's interest in the Premises (except in a sale-leaseback financing transaction), or in the event of the termination of any lease in a sale-leaseback financing transaction wherein Landlord is the lessee, attorn to and recognize such purchaser or assignee or mortgagee as Landlord under this Lease.

ARTICLE 13

DEFAULT

SECTION 13.01 DEFAULTS BY TENANT. The occurrence of any of the following shall constitute a default and breach of this Lease by Tenant:

A.: Monetary Defaults. Any failure by Tenant to pay the Rent or to make any other payment required to be made by Tenant hereunder when due. Notwithstanding the preceding sentence, Tenant shall not be in default with respect to the first two (2) failures in a calendar year, if Tenant pays the Rent or such other amount within five (5) days after Landlord delivers to Tenant written notice specifying such failure.

SECTION 13.02 REMEDIES OF LANDLORD. Upon the occurrence of any event of default specified in this Lease, Landlord, at its option, may have one or more of the following remedies, in addition to all other rights and remedies provided at law or in equity:

A.: Damages. Landlord may terminate this Lease and without further notice, take possession of the Premises and be entitled to recover as damages a sum of money equal to the total of (1) the cost of recovering the Premises, (2) the unpaid Rent earned at the time of termination, plus interest thereon, (3) Late Charges on unpaid Rent and accrued interest thereon, (4) damages for the

present value of the balance of the Rent for the remainder of the Term using a discount rate of ten percent (10%) less the fair market value for the Premises for the remainder of the Term using a discount rate of ten percent (10%) which fair market value shall be calculated (i) using only the remaining Term of the Lease, (ii) assuming a six month vacancy for marketing, and (iii) including no brokerage commissions or tenant improvement allowance, (5) reasonable costs of reletting and refurbishing the Premises, and (6) any other sum of money and damages owed by Tenant to compensate Landlord for the detriment caused by Tenant's failure to perform its obligations under this Lease specifically including, without limitation, the unamortized portion of any out-of-pocket expense by Landlord in connection with this Lease.

B.

Perform the Breached Covenant or Agreement. If Tenant's default is under Section 13.01B above, Landlord may, without obligation, and without waiving or releasing Tenant from the default or any other default or any other obligations of Tenant, perform the covenant, condition or agreement which is the subject of the default. All sums so paid by Landlord and all costs incurred by Landlord, including attorneys' fees, together with interest at the highest rate allowed by law but not in excess of the maximum rate that Landlord is permitted by law to charge, shall be payable to Landlord within thirty (30) days after written demand and Tenant covenants to pay any such sums, and Landlord shall have (in addition to any other right or remedy hereunder) the same rights and remedies in the event of the non-payment thereof by Tenant as in the case of default by Tenant in the payment of rent.

C.

Termination of Right to Possession/Reletting Premises.

1.

Taking Possession of Premises, Expelling Tenant, and Changing Locks.

2.

Reletting of Premises.

(a): Obligation to Use Some Efforts to Relet. If Landlord elects to terminate Tenant's right to possession of the Premises without terminating this Lease, Tenant shall continue to be liable for all Rent and Landlord agrees to use objectively reasonable efforts to relet the Premises, or any part thereof, to a substitute tenant or tenants, which reletting may be for a period of time equal to or lesser or greater than the remainder of the Term on whatever terms and conditions Landlord, in Landlord's commercially reasonable judgment, deems advisable.
(b): Meaning of Objectively Reasonable Efforts. The term "objectively reasonable efforts" shall mean that Landlord shall, not more than thirty (30) days after terminating Tenant's possession of the Premises, place the Premises on Landlord's inventory of available space, make Landlord's inventory available to brokers on request, advertise the Premises (along with Landlord's other inventory, if Landlord so chooses) for lease in a suitable trade journal or newspaper, and show the Premises (or portion thereof) to prospective tenants requesting to see the Premises or portion thereof. Notwithstanding the foregoing or any other provision to the contrary contained in this Lease, objectively reasonable efforts to relet the Premises shall not (i) require Landlord to give priority to the Premises over other premises owned or managed by Landlord or its affiliates; (ii) require Landlord to relet for less than market rent; (iii) require Landlord to relet to a tenant (or for a use) which is not in keeping with the standards of the Complex; or (iv) require Landlord to enter into a lease or sublease for less than the entire Building. Tenant shall be given a credit against the Rent due from Tenant to Landlord during the remainder of the Term in

the net amount of rent received from the new tenant; however, the net amount of such rent received from the new tenant shall first be applied to:

(i): all costs incurred by Landlord in reletting the Premises (including, without limitation, remodeling costs, brokerage fees, legal fees, advertising costs and the like);
(ii): the accrued sums, plus interest and late charges if in arrears, under the terms of this Lease;
(iii): Landlord's reasonable cost of recovering possession of the Premises; and
(iv): the cost of storing (for a period not to exceed thirty (30) days unless a longer period is mandated by law or judicial decree, after which period Tenant acknowledges that Landlord shall have the right to sell or give such property away and apply any proceeds therefrom to amounts owed by Tenant to Landlord hereunder) any of Tenant's property left on the Premises after reentry.

(c): Reletting Not Election to Terminate. Reletting of the Premises shall not be construed as an election on the part of Landlord to terminate this Lease.
(d): Landlord's Right to Terminate Lease Following Reletting. Notwithstanding any such reletting without termination, Landlord may at any time thereafter elect to terminate this Lease for such previous breach.
(e): Default of Substitute Tenant. Notwithstanding any provision in this Section 13 to the contrary, upon the default of any substitute tenant or upon the expiration of the lease term of such substitute tenant before the expiration of the Term, Landlord may, at Landlord's election, either relet to still another substitute tenant or otherwise exercise its rights under this Section 13.

D.: Termination of Lease. Landlord may terminate this Lease only by delivering to Tenant written notice of termination. If Landlord enters on the Premises with the intent of taking possession thereof and Landlord has not sent a written notice of termination of this Lease, then Landlord shall be deemed to have exercised its right of possession pursuant to paragraph C of this Section.
E.: Limitation on Landlord Liability. Any entry into and possession of the Premises by Landlord under this Article shall be without liability or responsibility for damages to Tenant and shall not be in lieu of or in substitution for any other rights of Landlord hereunder at law or in equity.
F.: Landlord's Right to Bring Suit on Rent. Tenant further agrees that Landlord may file suit from time to time to recover any sums due under the terms of this Article and that no recovery of any portion of the Rent due Landlord hereunder shall be any defense to any subsequent action brought for any amount not theretofore reduced to judgment in favor of Landlord.
G.: Automatic Termination of Lease/Bankruptcy. If, at any time prior to the Commencement Date, any action is taken by or against Tenant in any court pursuant to any statutes pertaining to bankruptcy or insolvency or the reorganization of Tenant, Tenant makes any general assignment for the benefit of creditors, a trustee or receiver is appointed to take possession of all or substantially all of Tenant's assets or of Tenant's interest in this Lease, or there is an attachment, execution or other judicial seizure of all or substantially all of Tenant's assets or of Tenant's interest in this Lease, then this Lease shall ipso facto be canceled and terminated and of no further force or effect. In such event, neither Tenant nor any person claiming through or under Tenant or by virtue of any statute or of any order of any court shall be entitled to possession of the Premises or any interest in this Lease and Landlord shall, in addition to any other rights and remedies under this Lease, be entitled to retain any rent, security deposit, or other monies received by Landlord from Tenant as liquidated damages.

H.: Tenant's Obligation to Mitigate. Tenant shall also be obligated to use reasonable efforts to mitigate any losses suffered or to be suffered by Landlord on account of Tenant's default, any such reletting, or any Landlord default under this Lease.

SECTION 13.03 WAIVER OF STATUTORY LIENS. Landlord and Tenant hereby waive any statutory liens that such party may have under law.

SECTION 13.04 DEFAULTS BY LANDLORD.

A.: Landlord Default. Except as otherwise provided in this Lease, if Landlord fails to perform any of its obligations hereunder, and said failure continues for a period of thirty (30) days after written notice thereof from Tenant to Landlord (unless such failure cannot reasonably be cured within thirty (30) days and Landlord shall have promptly commenced to cure said failure within said thirty (30) days and continues diligently to pursue the curing of the same) then Landlord may be held to be in default hereunder.
B.: Money Judgments. If Landlord shall be in default under this Lease and, if as a consequence of such default, Tenant shall have the right to recover a money judgment against Landlord, then such judgment shall be satisfied only out of the right, title, and interest of Landlord in the Project as the same may then be encumbered. If such judgment cannot be satisfied in full in such a manner, then Tenant may offset Rent until it has satisfied the full amount of such judgment. In no event shall Tenant have the right to levy execution against any property of Landlord other than its interest in the Project as hereinbefore expressly provided.
C.: Limited Right to Cure and Offset. If (i) a Landlord default occurs, (ii) such default materially and adversely affects Tenant's operations in the Project, (iii) the default is reasonably possible to cure, and (iv) Tenant delivers at least five (5) days written notice that it intends to cure Landlord's default, then and only then Tenant shall have the right to cure Landlord's default. If such cure is accomplished, Tenant shall send copies of the paid invoices from the vendors who performed the work to complete the cure of Landlord's default. Landlord will, within thirty (30) days after receiving such invoices, reimburse Tenant for the invoiced costs. If Landlord fails to reimburse Tenant for any such invoiced costs within the required 30-day period, Tenant shall have the further right to offset such invoiced amount against the Basic Rent payments next becoming due, subject to the condition that the amount offset against any one installment of Basic Rent shall not exceed twenty-five percent of the Basic Rent installment.
D.: Notwithstanding the foregoing, so long as the Building is owned by Landlord, any partners of Landlord, any entity which directly or indirectly controls Landlord, any person whom directly or indirectly controls Landlord or any entity controlled directly or indirectly by ▇▇▇▇▇▇ ▇. ▇▇▇▇▇▇▇, or any entity in which ▇▇▇▇▇▇ ▇. ▇▇▇▇▇▇▇ owns at least a 25% direct or indirect interest (provided ▇▇. ▇▇▇▇▇▇▇ also controls voting of such entity), Tenant will not exercise its cure or offset rights under paragraph C immediately preceding. Control may be achieved through ownership interests, voting interests, voting blocks or any combination of the foregoing.

MISCELLANEOUS PROVISIONS

SECTION 16.01 ESTOPPEL CERTIFICATE.

A.

Tenant shall, within ten (10) days after receipt of written request therefor, without additional consideration, deliver an Estoppel Certificate, delivered to Landlord consisting of statements, if true, that:

1.: This Lease is in full force and effect, with rental paid through [list applicable date];
2.: This Lease has not been modified or amended;
3.: Landlord is not in default and Landlord has fully performed all of Landlord's obligations hereunder, and any such further consents and instruments of a similar nature evidencing the agreement of Tenant to the mortgage or other hypothecation by Landlord of the reversionary interest of Landlord hereunder as may be reasonably requested by Landlord or any mortgagee of Landlord. In the event that, in Tenant's opinion, any of the above statements are not true, Tenant shall indicate its opinion of the true state of affairs by either (i) stating separately the correct entries or (ii) modifying the statement(s) above in order to make it (them), in Tenant's opinion, true and correct; and
4.: Such further matters as Landlord may reasonably require and Tenant reasonably approves.

B.

Failure to Deliver Estoppel Letter. Tenant's failure to supply such estoppel certificate within thirty (30) calendar days of Tenant's receipt of such written request therefor shall be an event of default by Tenant (meaning that Tenant shall not be entitled to any further cure rights under Section 13.02 above), which shall entitle Landlord to recover from Tenant a $25.00 per day delay charge and any other remedies provided for in this Lease.

C.

Number of Permitted Estoppel Certificates. After Tenant has delivered two (2) estoppel certificates in any one calendar year, Tenant shall not be required to deliver any further estoppel certificates during such calendar year, unless and until Landlord delivers to Tenant the sum of $1,000 for each such additional estoppel letter.

SECTION 16.04 WAIVER. No waiver of any provision of this Lease or of any breach hereunder shall be deemed to be a waiver of any other provision hereof, or of any subsequent breach of the same or any other provision. Consent to or approval of any act requiring consent or approval shall not be deemed to render unnecessary the obtaining of consent to or approval of any subsequent act. No act or

thing done by Landlord's agents during the term of this Lease shall be deemed an acceptance of a surrender of the Premises, unless done in writing signed by Landlord. The delivery of the keys to any employee or agent of Landlord shall not operate as a termination of the Lease or a surrender of the Premises. The acceptance of any Rent by Landlord following a breach of this Lease by Tenant shall not constitute a waiver by Landlord of such breach or any other breach unless such waiver is expressly stated in writing signed by Landlord.

SECTION 16.05 APPLICABLE LAW. This Lease shall be governed by and construed pursuant to the laws of the State of Texas.

SECTION 16.06 COMMON FACILITIES.

Tenant shall have no right to use any of the Common Facilities, except that Landlord will allow Tenant's qualified contractors to access the electrical room, telephone rooms, above ceiling areas, and risers used for installations of various conduit and wires in and to the Premises, provided (1) such contractors arrange access through Landlord and comply with Landlord's reasonable rules and regulations, (2) any installations in and modifications of such rooms, above ceiling areas and risers shall comply with all requirements pertaining to Tenant Alterations, and (3) Landlord shall have the right to approve all such installations and modifications to any such rooms, above ceiling areas and risers (not to be unreasonably withheld). Notwithstanding the foregoing, during the term of this Lease, Landlord shall not have access to the Secured Areas unless (i) in the event of an emergency, or (ii) Landlord is accompanied into such Secured Areas by an employee, agent or representative of Tenant. In the event Tenant fails or refuses to provide security for the Secured Areas twenty-four hours per day, seven days per week during the term, then Tenant shall immediately thereafter provide Landlord with keys, a valid access pass card and/or security codes to such Secured Areas.

Landlord warrants that it has had no dealings with any real estate broker or agent in connection with the negotiation of this Lease and knows of no other real estate broker or agent who is entitled or might be entitled to a commission in connection with this Lease. Tenant acknowledges and agrees that Tenant is solely responsible for the payment of all commissions that may be due and owing to Tenant's Broker as a result of Tenant entering into this Lease with Landlord. Tenant agrees to indemnify, defend and hold harmless Landlord from and against any liability or claim, whether meritorious or not, made against Landlord by any broker (including Tenant's Broker) who claims to be Tenant's broker or otherwise claims a commission is due and payable due to the acts of Tenant or its employees, agents or representatives. If any Broker other than the Tenant's Broker makes any claim for a commission from Tenant by virtue of the acts of the Landlord, then Landlord will indemnify, defend and hold Tenant harmless from any such claim arising from the acts of Landlord.

SECTION 16.09 SEVERABILITY. If any provision of this Lease or the application thereof to any person or circumstances shall be invalid or unenforceable to any extent, the remainder of this Lease and the application of such provisions to other persons or circumstances shall not be affected thereby and shall be enforced to the greatest extent permitted by law.

Notwithstanding the foregoing, (1) Tenant shall not be charged interest with respect to the first and second failures during a calendar year to pay the amounts as specified in paragraphs (a) and (d) above, so long as Tenant pays to Landlord the applicable amount within ten (10) calendar days after Landlord delivers to Tenant written notice that the applicable amount was not paid when due and (2) Landlord shall not be charged for interest with respect to the first and second failures in a calendar year to pay the amounts specified in paragraph (c) and (b) above, so long as Landlord pays to Tenant the applicable amount within ten (10) days after Tenant delivers to Landlord written notice that the applicable amount was not paid when due.

SECTION 16.13 TIME. Time is of the essence in this Lease and in each and all of the provisions hereof. Any reference to "days" herein shall refer to calendar days unless otherwise expressly stated.

NON-DISTURBANCE, AND ATTORNMENT AGREEMENT

NOTICE:

THIS SUBORDINATION, NON-DISTURBANCE AND ATTORNMENT AGREEMENT RESULTS IN YOUR LEASEHOLD ESTATE IN THE PROPERTY BECOMING SUBJECT TO AND OF LOWER PRIORITY THAN THE LIEN OF SOME OTHER OR LATER SECURITY INSTRUMENT.

THIS AGREEMENT is entered into by and among Tenant, Landlord and Beneficiary and affects the Property described in Exhibit "A" attached hereto. The terms "Tenant," "Landlord," "Beneficiary," "Premises," "Property," "Loan," "Note" and "Mortgage" are defined in the Schedule of Definitions attached hereto as Exhibit "B." This Agreement is entered into with reference to the following facts:

A. Landlord and Tenant have entered into the Lease covering the Premises on the Property.

B. Beneficiary has made the Loan to Landlord evidenced by the Note, which Note is secured by the mortgage covering the Property.

C. The parties hereto desire expressly to subordinate the Lease to the lien of the Mortgage, it being a requirement of the Loan that the lien of the Mortgage be unconditionally and at all times prior and superior to the leasehold interests and estates created by the Lease.

D. Tenant has requested that Beneficiary agree not to disturb Tenant's possessory rights in the Premises in the event Beneficiary should foreclose the Mortgage, provided that Tenant attorns to Beneficiary or the purchase at any foreclosure or trustee's sale of the Property.

NOW, THEREFORE, in consideration of the mutual covenants contained herein and of other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties agree as follows:

1. Subordination.

Notwithstanding anything to the contrary set forth in the Lease, the Lease and the leasehold estate created thereby and all of Tenant's rights thereunder shall be and shall at all times remain subject, subordinate and inferior to the Mortgage and the lien thereof, and all rights of Beneficiary thereunder and to any and all renewals, modifications, and extensions thereof.

2. Acknowledgement and Agreement by Tenant. Tenant acknowledges and agrees that:

(a) Beneficiary, in making any disbursements to Landlord, is under no obligation or duty to oversee or direct the application of the proceeds of such disbursements.

(b) Tenant will not terminate or cancel the Lease or the term thereof or claim partial or total eviction by reason of a default by Landlord thereunder unless and until (i) Tenant has given written notice of such act or omission to Landlord and Beneficiary, (ii) Landlord has failed to remedy such act or omission within the applicable cure period set forth in the Lease, and (iii) Beneficiary has failed to remedy such act or omission within fifteen (15) days after the expiration of Landlord's cure period for such act or omission, provided, however, that if such remedy cannot be reasonably completed within such fifteen (15) day period and Beneficiary begins such remedy within such fifteen (15) day period and diligently prosecutes such remedy to

Exhibit J – 1

completion, Tenant shall have no right to cancel or terminate the Lease. Beneficiary's cure periods shall be subject to extension for Force Majeure delays, which shall include any acts of God, riot or civil commotion, strikes, governmental preemption, priorities or other controls in connection with a national or other public emergency, or shortages of fuel, supplies or labor resulting therefrom, or any other cause of any kind whatsoever which is beyond Beneficiary's reasonable control.

(c) Tenant has notice that the Lease and the rent and other sums due thereunder have been assigned or are to be assigned to Beneficiary as security for the Loan secured by the Mortgage. In the event that Beneficiary, in accordance with Section 7 hereof, notifies Tenant in writing of a default under the Mortgage and demands that Tenant pay its rent and all other sums due under the Lease to Beneficiary, Tenant shall honor such demand and pay its rent and all other sums due under the Lease directly to Beneficiary.

(d) This Agreement satisfies any condition or requirement in the Lease relating to the granting of a non-disturbance agreement.

3. Foreclosure and Sale.

(b) If Beneficiary or Beneficiary's Successor succeeds to the interest of Landlord under the Lease (herein a "Successor Landlord") such party shall be bound to Tenant under all of the terms, covenants and conditions of the Lease, including, without limitation, the rental and other sums payable by Tenant thereunder, and Tenant shall, from and after such party's succession to the interests of Landlord under the Lease, have the same rights under the Lease and the same remedies against such party for the Breach of the Lease that Tenant would have had under the Lease against Landlord if such party had not succeeded to the interests of Landlord; provided, however, that if such interest is acquired by Beneficiary or Beneficiary's Successor, such party shall not be:

(v) bound by any obligation of any landlord (including Landlord) to make any payment to Tenant or to undertake or complete any construction of or any portion of the Premises or Property or be subject to any offset, defense or enforcement of remedies arising from the failure of any landlord (including Landlord) to do so, except that Successor Landlord shall be liable for the timely return of any security deposit or other deposit actually received by Successor Landlord to the extent (a) Tenant has notified Successor Landlord of Landlord's failure to pay such sum in accordance with the terms of the Lease and (b) to the extent Tenant is due such sum in accordance with the terms of the Lease; or

NON-FOREIGN CERTIFICATE

Section 1445 of the United States Internal Revenue Code of 1986 (as amended, the "Code"), provides that a transferee of a U.S. real property interest must withhold tax if the transferor is a "foreign person" (as defined in the Code). For U.S. tax purposes (including Section 1445), the owner of a disregarded entity (which has legal title to a U.S. real property interest under local law) will be the transferor of the property and not the disregarded entity. To inform the transferee that withholding of tax is not required upon the disposition of a U.S. real property interest by Sabre Inc. ("Transferor"), the undersigned hereby certifies the following on behalf of Transferor:

a.: Transferor is not a foreign corporation, foreign partnership, foreign trust, or foreign estate (as those terms are defined in the Internal Revenue Code and Income Tax Regulations).
b.: Transferor is not a disregarded entity as defined in Treas. Reg. Section 1.1445-2(b)(2)(iii).
c.: Transferor's U.S. employer identification number is ▇▇-▇▇▇▇▇▇▇.
d.: Transferor's office address is ▇▇▇▇ ▇▇▇▇▇ ▇▇▇▇▇, ▇▇▇▇▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇▇.

Transferor understand that this certification may be disclosed to the Internal Revenue Service by ▇▇▇▇▇▇▇ Partners-Solana Limited Partnership and that any false statement contained herein could be punished by fine, imprisonment, or both.

Under penalties of perjury I declare that I have examined this certification and to the best of my knowledge and belief it is true, correct, and complete, and I further declare that I have authority to sign this document on behalf of Transferor.
