Commercial Lease. Start a state-specific lease for the rental of commercial property. Specify the term and rent due, as well as whether the landlord or tenant is responsible for property taxes, insurance, and maintenance and repairs.
Commercial Sublease. When a tenant vacates commercial property before the lease term has expired, it may be able to rent the premises to a third party. The tenant would be the sublessor and the third party would be the sublessee. Besides preparing a sublease, both parties will want to review the provisions for assignment or subletting in the original lease agreement between the landlord and the sublessor.
Sublease Agreement. Tenants of residential property should prepare a sublease agreement if they are seeking to sublease a room or the entire apartment or house to a third party. All parties should review the original lease agreement to see if there are any restrictions on subletting or assigning the premises.
Triple Net Lease. Triple net leases are a type of commercial leases where the tenant has to pay for property taxes, insurance, utilities, and maintenance, in addition to the monthly rent.
Office Space Lease. When renting an office space, tenants should understand the amount of the rent and duration of the lease. Other important terms include whether the space can be subleased, which parties are responsible for maintenance, and whether any furniture and furnishings will be provided.

WITNESSETH: For and in consideration of the covenants and agreements contained in this Lease Landlord demises unto Tenant and Tenant leases from Landlord all of that office space outlined in red on the plan titled "Sixth (6), Fifth (5th), Second (2nd) and First (1st) Floors, ^** , attached hereto and made a part hereof by reference and marked Exhibit A, which said area comprises approximately 44,800 rentable square feet, calculated according to the ** Standard Method of Measurement (January 1, 1989), together with the right to the non-exclusive use, in common with others, of such footways, hallways and other facilities designed for common use as may be installed by Landlord (the �Common Areas"), all subject to the terms and conditions of this Lease (the "Demised Premises").

I. Mutual Covenants

It is mutually agreed as follows:

I.1. Demise and Rental. Tenant shall use and occupy the Demised Premises for office space including the operation of a data processing facility for the term (the "Term") of 9 years, 5-1/2 months (or until the Term shall cease and expire as hereinafter provided) commencing on the 15th day of May, 1992 (the "Commencement Date"), and ending on the day on which the Deed of Lease of even date herewith between Landlord and Tenant (the "Data Center Lease") for a data center (the "Data Center") to be constructed adjacent to the building of which the Demised Premises are a part (the "Building") terminates pursuant to Section 2 thereof, both dates inclusive, the said Tenant yielding and paying as base rent ("Rent") therefor the sum of Forty-Four Thousand Eight Hundred and NO/100 Dollars ($44,800.000) per month, subject to escalation as provided herein, without deduction, non-judicial set-off or demand, payable in advance, on the first day of each and every month, beginning with the month after the month in which Substantial Completion of the Tenant Improvements (as defined in Section 2 of the Addendum) occurs and continuing throughout the Term, at the office of the Landlord or at such other place as the Landlord may designate in writing. Rent .checks are to be made payable to ^** or such other person, firm or corporation as the Landlord may designate in writing.

I.2. Damage by Tenant.

Subject to the provisions of Section 10 of the Addendum, in the event that the Tenant shall fail to do so, then the Landlord shall have the right to make repairs, alterations and replacements necessary to repair or restore such injury or breakage (structural, non-structural or otherwise) and any charge or cost so incurred by the Landlord shall be paid by the Tenant with the right on the part of the Landlord to elect in its discretion, to regard the same as additional rent, in which event such cost or charge shall become additional rent payable with the installment of Rent next becoming due or thereafter falling due under the terms of this Lease.

^**	Omitted pursuant to a confidential treatment request. The confidential portion has been filed separately with the SEC.

I.3. Landlord's Liability. Except to the extent resulting from Landlord's negligence or willful misconduct, the Landlord shall not be liable for any accident or damage resulting through the use or operation of elevators, or heating, cooling, electrical or plumbing apparatus. All personal property of the Tenant in the Demised Premises or in the Building, shall be at the sole risk of the Tenant except to the extent resulting from Landlord's negligence or willful misconduct.

Landlord shall in no event be liable for damages to property resulting from water, steam or other causes except to the extent resulting from Landlord's negligence or willful misconduct. Except to the extent resulting from Landlord's negligence or willful misconduct, Landlord assumes no liability or responsibility whatever with respect to the conduct and operation of the business to be conducted in the Demised Premises nor for any loss or damage of whatsoever kind or by whomsoever caused to personal property, documents, records, monies or goods of the Tenant or to anyone in or about the Demised Premises by consent of the Tenant, however caused. Notwithstanding anything contained in this Lease or under applicable law to the contrary, the partners of Landlord who are natural persons, including without limitation its general partners, shall have no personal liability under this Lease collectively or individually, it being agreed that Tenant's sole recourse shall be against the assets of the Landlord as an entity.

I.4. Indemnity

I.4.a. Tenant's Indemnity. Tenant shall indemnify and hold Landlord harmless from and against all demands, loss, liability, claims, expenses, causes of action, fines, penalties and damages arising from the Tenant's use of the Demised Premises or its breach of any provision of this Lease, and from the conduct of Tenant's business or from any activity, work or things done, permitted or suffered by Tenant in or about the Demised Premises which arise during the Term of the Lease, and shall further indemnify and hold harmless Landlord from and against any and all claims arising from the negligence or willful misconduct of Tenant or any of Tenant's agents, contractors, employees, licensees or invitees and from and against all costs, attorney's fees, expenses and liabilities incurred in the defense of any such claim or any action or proceeding brought thereon, and in case any action or proceeding be brought against Landlord by reason of any such claim, Landlord shall provide Tenant with prompt written notice of such action or proceeding, and Tenant shall have the right to defend the same at Tenant's expense. Tenant shall be entitled to timely notice and reasonable cooperation from Landlord, as well as to control of the defense and settlement of all such claims. Tenant shall not indemnify and hold Landlord harmless from and against any demands, loss, liability, claims, expenses, causes of action, fines, penalties and damages arising from the negligent or wrongful acts of Landlord, its employees, contractors, agents or representatives.

I.4.b. Landlord's Indemnity. Landlord shall indemnify and hold Tenant harmless from and against any and all demands, loss, liability, claims, expenses, causes of action, fines, penalties and damages arising from Landlord's actions or inactions or any activity, work or things done, permitted or suffered by Landlord in or about the Premises pursuant to Landlord�s

obligations under this Lease, or Landlord's breach of any provision of this Lease, and shall further indemnify and hold harmless Tenant from and against any and all claims arising from the negligence or willful misconduct of Landlord or any of Landlord's agents, contractors, employees, licensees or invitees and from and against all costs, attorney's fees, expenses and liabilities incurred in the defense of any such claim or any action or proceeding brought thereon, and in case any action or proceeding be brought against Tenant by reason of any such claim, Landlord, upon timely written notice from Tenant, shall defend the same at Landlord's expense. Landlord shall be entitled to timely notice and reasonable cooperation from Tenant, as well as to control of the defense and settlement of all such claims. Landlord shall not indemnify and hold Tenant harmless from and against any demands, loss, liability, claims, expenses, causes of action, fines, penalties and damages arising from the negligent or wrongful acts of Tenant, its employees, contractors, agents or representatives.

I.5. Bankruptcy of Tenant. If the Tenant shall make an assignment of its assets for the benefit of creditors, or if the Tenant shall file a voluntary petition in bankruptcy, or if an involuntary petition in bankruptcy or for receivership be instituted against the Tenant and the same be not dismissed within sixty (60) days of the filing thereof, or if the Tenant be adjudged bankrupt, then and in any of said events this Lease shall immediately cease and terminate at the option of the Landlord with the same force and effect as though the date of occurrence of said event was the day herein fixed for expiration of the Term of this Lease.

I.6. Tenant Default. Subject to Section 10 of the Addendum, if the Tenant shall fail to pay the Rent or any installments thereof as aforesaid at the time the same shall become due and payable and any additional rent as herein provided although no demand shall have been made for the same; or if the Tenant shall violate or fail or neglect to keep and perform any of the covenants, conditions and agreements contained in this Lease or the Data Center Lease on the part of the Tenant to be kept and performed or if the Demised Premises shall become deserted, then, at the option of the Landlord, the Tenant's right of possession shall thereupon cease and determine, and the Landlord shall be entitled to the possession of the Demised Premises and to reenter the same without demand of rent or demand of possession of the Demised Premises and may forthwith proceed to recover possession of the Demised Premises by process of law, including by self-help in accordance with law, any notice to quit, or of intention to reenter the same being hereby expressly waived by the Tenant. And, in the event of such reentry by process of law or otherwise, the Tenant nevertheless agrees to remain answerable for any and all damage, deficiency, or loss of rent which the Landlord may sustain by such reentry, and in such case, the Landlord reserves full power, which is hereby acceded to by the Tenant, to relet the Demised Premises for the benefit of the Tenant, in liquidation and discharge, in whole or in part, as the case may be, of the liability of the Tenant under the terms and provisions of this Lease. Landlord shall not unreasonably refuse to consent to an assignment or sublease proposed by Tenant in mitigation of Tenant's liability, provided the conditions of Section 12 of the Addendum are met. And it is further provided, that if, under the provisions hereof applicable summary process shall be served, and a compromise or settlement thereof shall be made, it shall not be constituted as a waiver of any breach of any covenant, condition or agreement herein contained and that no waiver of any breach of any covenant, condition or agreement herein contained shall operate as a waiver of the covenant, condition or agreement itself, or of any subsequent breach thereof. No provision of this Lease shall be deemed to have been waived by either party unless such waiver shall be in writing signed by such party. No payment by Tenant,

or receipt by Landlord of a lesser amount than the monthly installments of Rent herein stipulated shall be deemed to be other than on account of the earliest stipulated Rent nor shall any endorsement or statement on any check or payment as Rent be deemed an accord and satisfaction, and the Landlord may accept such check or payment without prejudice to the Landlord's right to recover the balance of such Rent or pursue any other remedy in this Lease provided.

I.7. Landlord Default

I.7.a. Landlord's failure materially to observe or perform any of the material covenants, conditions or provisions of, or Landlord's material breach of any material representation or warranty set forth in, this Lease or the Data Center Lease to be observed or performed by Landlord (whether monetary or otherwise and including, without limitation, Landlord's obligation to provide parking in accordance with this Lease), where such failure shall continue for a period of thirty (30) days after written notice thereof from Tenant, to Landlord and any first mortgage lender or mortgagee (a "First Mortgage Lender") of Landlord if Landlord has notified Tenant of the name and address of such First Mortgage Lender, shall constitute a default of this Lease by Landlord ("Landlord Default"); provided, however, that if such failure is not reasonably capable of being cured within such thirty (30) day period and if Landlord or First Mortgage Lender promptly commences and diligently pursues the cure of such failure, then such period shall be extended as necessary to permit Landlord to cure such failure.

I.7.b. In the event of any Landlord Default, without limiting Tenant in the exercise of any right or remedy that Tenant may have by reason of such landlord Default:

(i) Tenant may terminate this Lease and, at its option, the Data Center Lease.

(ii) If Tenant does not terminate this Lease, after providing written notice to Landlord, Tenant may do any act in the doing of which Landlord has defaulted, except that Tenant shall not make payment of any financial obligation of the Landlord to any third party which may affect property interests of the Landlord in addition to the Demised Premises, such as for mortgages, taxes or insurance, or repairs to the foundation or structure of the Building, base building systems or common areas, and the doing of such act by Tenant shall not relieve Landlord of any other of its obligations under this Lease or the Data Center Lease.

(iii) Whether or not Tenant takes any action pursuant to Section I.7.b(i) or I.7.b(ii), Tenant may pursue any right or remedy now or hereafter available to Tenant under the laws or judicial decisions of the Commonwealth of Virginia. Landlord shall be liable for all expenses reasonably incurred by Tenant with respect to any Landlord Default including, but not limited to, the reasonable costs of taking any action pursuant to Section I.7.b(ii), and shall pay such amounts to Tenant within thirty (30) days after Landlord's receipt of written demand therefor from Tenant, including appropriate supporting documentation.

I.8. Subordination. This Lease shall be subject and subordinate to any ground lease, mortgage, deed of trust, or any other hypothecation or security now or hereafter placed upon all or any part of the Demised Premises; any and all advances made on the security thereof; all renewals, modifications, consolidations, replacements and extensions thereof when with respect

to which Landlord provides to Tenant a non-disturbance agreement reasonably acceptable to Tenant from any holder of such an interest in the Demised Premises. Subject to the provisions of this Section I.8, Tenant agrees to execute any documents required to effectuate an attornment, a subordination or to make this Lease prior to the lien of any mortgage, deed of trust or ground lease, as the case may be. In the event that Tenant fails to execute such documents within thirty (30) days after Landlord makes written demand therefor, Tenant does hereby make and appoint Landlord as Tenant's attorney-in-fact, for the sole purpose or executing said documents in Tenant's place and stead, which such appointment shall be deemed coupled with an interest and irrevocable.

I.9. Condemnation

I.9.a. If the Demised Premises or any portion thereof are taken under the power of eminent domain, or sold under the threat of the exercise of said power (all of which are herein called "Condemnation"), this Lease shall terminate as to the part so taken as of the date the condemning authority takes title or possession, whichever occurs first (hereafter referred to as the "Condemnation Date"). If more than fifty percent (50%) of the rentable floor area of the Demised Premises is taken by Condemnation and not restored by Landlord; or if, as a result of the Condemnation, Tenant is unable to make any use of the Demised Premises for the operation of its business as set forth in Section II.4(a) below and not restored by Landlord, either Landlord or Tenant may, at its option, to be exercised in writing within fifteen (15) days after the condemning authority shall have taken possession, terminate this Lease as of the Condemnation Date. If neither Landlord nor Tenant terminates this Lease in accordance with the foregoing, this Lease shall remain in full force and effect as to the remaining portion of the Demised Premises, except that the Rent shall be reduced in the proportion that the rentable floor area of the Demised Premises taken bears to the total rentable floor area of the Demised Premises before the Condemnation.

I.9.b. If any portion of Tenant's Parking (as defined in Section 16 of the Addendum) is taken, Landlord shall provide for Tenant's use the same number of spaces after such Condemnation as were provided pursuant to Section 16 of the Addendum before such Condemnation subject to equitable adjustment to reflect staff size reduction effected by Tenant, in Tenant's sole discretion. Such spaces shall be located reasonably adjacent to the Demised Premises and no less favorably than for any other tenant of the ^**.

I.9.c. In the event that this Lease is not terminated by reason of a Condemnation, Landlord shall repair any damage to or loss of the Demised Premises or Parking Area (as defined in Section 16 of the Addendum) and, if necessary, Landlord shall perform such construction as may be necessary to render the remaining Demised Premises a sound architectural unit substantially suitable for the purposes authorized Tenant in Section II.4(a) below, all according to the provisions for rebuilding stated in Section 11(b) of the Addendum, utilizing any available Condemnation proceeds resulting from such Condemnation, subject to any conditions on such use set by Landlord's construction lender or First Mortgage Lender. The parties shall use all reasonable efforts to cooperate to avoid unnecessary disruption of Tenant's operation of its business.

^**	Omitted pursuant to a confidential treatment request. The confidential portion has been filed separately with the SEC.

I.9.d. In the event of a Condemnation, Tenant shall not have any claim or right to any portion of the amount that may be awarded as damages or paid as a result of any such Condemnation; and all right of the Tenant to damages therefor, if any, are hereby assigned by the Tenant to the Landlord. Except for the obligations of Landlord stated in this Section I.9, Tenant shall have no claim against Landlord for damages suffered by Tenant as a result of such Condemnation.

I.10. Nonpayment by Tenant. If the Landlord shall incur any charge or expense on behalf of the Tenant under the terms of this Lease such charge or expense shall be considered additional rent hereunder, in addition to and not in limitation of any other rights and remedies which the Landlord may have in case of the failure by the Tenant to pay such sums when due, and subject to the provisions of Section 10 of the Addendum, such nonpayment shall entitle the Landlord to the remedies available to it hereunder for nonpayment of Rent.

I.11. Construction. Feminine or neuter pronouns shall be substituted for those of the masculine form, and the plural shall be substituted for the singular number, in any place or places herein in which the context may require such substitution or substitutions. The Landlord herein for convenience has been referred to in neuter form.

I.12. Integration; Dual Termination

I.12.a. Integration. This Lease and the Data Center Lease contain the entire understanding between the parties as to the subject matter hereof and supersede any prior understanding and agreements between them respecting said subject matter. Except for this Lease and the Data Center Lease, there are no representations, agreements, arrangements or understandings, oral or written, between the parties hereto. This Lease can be modified only by a writing signed by both of the parties hereto or their duly authorized agents. Tenant acknowledges that except as otherwise specifically stated in this Lease Tenant assumes all responsibility regarding the Occupational Safety and Health Act; the legal use and adaptability of the Demised Premises; and the compliance of the Demised Premises with all applicable laws and regulations in effect during the term of this Lease.

I.12.b. Dual Termination. Any right of Tenant to terminate or cancel this Lease shall be deemed to include the right to terminate or cancel the Data Center Lease on sixty (60) days' notice, and any right of Tenant to terminate or cancel the Data Center Lease shall be deemed to include the right to terminate or cancel this Lease on sixty (60) days' notice. Tenant may terminate or cancel either this Lease or the Data Center Lease, pursuant to its terms, without terminating or cancelling the other. If Landlord terminates this Lease pursuant to Section I.9.a or to Section 11(a) of the Addendum hereto, then Tenant shall have the right to terminate the Data Center Lease on sixty (60) days' notice; and if Landlord terminates the Data Center Lease pursuant to Sections 8.1 or 13.1 thereof, then Tenant shall have the right to terminate this Lease on sixty (60) days' notice.

I.13. Governing Law. The laws of the Commonwealth of Virginia, without giving effect to the conflict of laws provisions thereof, shall govern the validity, interpretation, performance and enforcement of this Lease.

I.14. Successors and Assigns. This Lease and the covenants and conditions herein contained shall inure to the benefit of and be binding upon Landlord, its successors and assigns, and shall be binding upon Tenant, its successors, assigns, heirs, executors, administrators and

legal representatives, and shall inure to the benefit of Tenant and only such assigns of Tenant as have received Landlord's written approval prior to assignment.

II. Tenant's Covenants

Tenant covenants and agrees as follows:

II.1. Compliance with Law. Tenant shall comply with any and all requirements of any of the constituted public authorities, and with the terms of any State or Federal statute or local ordinance or regulation applicable to Tenant or its use of the Demised Premises, and save Landlord harmless from penalties, fines, costs, expenses or damages resulting from failure to do so.

II.2. Notice of Damage. Tenant shall give to Landlord prompt written notice of any accident, fire or damage occurring on or to the Demised Premises and the Common Areas (as defined above) of which Tenant has actual knowledge.

II.3. Acceptance of Premises. Tenant hereby takes and holds said Demised Premises at the Rent hereinabove specifically reserved and payable as aforesaid, and subject to the terms and conditions herein contained.

II.4. Use

II.4.a. Use. Tenant may use and occupy the Building solely for office purposes, including an employee cafeteria, the operation of a computer data center or data processing facility, and for such other lawful purposes as may from time to time be approved by Landlord, which approval shall not be unreasonably withheld, conditioned or delayed, but in no event shall Tenant use the Premises in any manner prohibited by law (including, without limitation, zoning ordinances), this Lease or building and use restrictions, covenants or conditions now or hereafter of record during the Term. During the Term, subject to Section 17 of the Addendum, Tenant may install externally mounted equipment on or at the Building, including on the roof thereof, such as satellite dishes, communications antennae and security devices including lighting with Landlord's approval, such approval not to be unreasonably withheld, conditioned or delayed, and Landlord shall assist Tenant in obtaining necessary governmental licenses or approvals.

II.4.b. Zoning Representation. Landlord represents and warrants that, pursuant to the ^** zoning ordinance and the current district boundaries in effect on the date hereof (the "Zoning Ordinance"), the Building lies within the ^**. Landlord has filed a rezoning application with ^** seeking a rezoning of the Building site from ^**. Landlord represents and warrants that uses described in Section II.4.a, above, are, as of the date hereof, permitted uses in both the ^** zones under the Zoning Ordinance. Landlord further represents and warrants that on the date hereof it has received no formal notice of pending amendments to the Zoning Ordinance that would change the permitted uses on the Building site, and covenants that if at any time during the Term it receives such notice it will promptly send a copy to Tenant. Landlord covenants that it has not taken and will not take any actions that would cause Tenant's uses permitted hereunder to become nonconforming uses or not permitted uses during the Term or any extension of the Term.

^**	Omitted pursuant to a confidential treatment request. The confidential portion has been filed separately with the SEC.

II.4.c. Assumptions and Qualifications. The foregoing representations and warranties are subject to the following assumptions and qualifications:

(i) Virginia Code Sections 15.1-486, et seq. (the "Enabling Legislation") authorizes the local governing body, in this instance the Board of Supervisors of ^**, to classify the territory under its jurisdiction into zoning districts to regulate land use and development. The Zoning Ordinance recites that it was adopted by ordinance pursuant to the Enabling Legislation. Landlord has assumed, based solely upon such recitation, that the Zoning Ordinance was duly authorized and adopted.

(ii) The site, the Building and the use thereof are subject to all of the other provisions of the Zoning Ordinance, as amended, including without limitation, site plan and public facility requirements, and any occupancy of the Building is subject to the issuance of a nonresidential use permit. Also, the use of the Building is subject to any and all other applicable laws, rules, regulations, orders and ordinances of the United States, Commonwealth of Virginia ^** .

(iii) If any of the representations or warranties set forth in this Section II.4 is untrue, or if the Zoning Ordinance or any other law, statute or ordinance affecting the permitted uses of the site is changed as a result of any actions by Landlord or any party affiliated with Landlord at any time during the Term or any extension thereof, so that the Building cannot be used as stated in this Section II.4a, then Tenant shall have the right to terminate this Lease and, at Tenant's option, the Data Center Lease upon thirty (30) days' prior written notice to Landlord, and Tenant shall have no further liability to Landlord thereunder, except under those provisions which would normally survive termination; provided, however, that Tenant shall have no right to terminate this Lease during the pendency of any action to secure a rezoning of the Building site that would make office uses permitted uses on the site provided that Tenant is permitted to carry on its business after such action and during the pendency of such action in the same manner as immediately before such change. Landlord shall undertake diligent efforts to prosecute such rezoning action at Landlord's expense promptly after it learns of such change.

II.5. Maintenance.

ADDENDUM TO OFFICE LEASE

DATED April 18, 1991 ENTERED INTO BY AND BETWEEN ^**, A VIRGINIA LIMITED PARTNERSHIP, AS LANDLORD, AND VISA U.S.A. INC., AS TENANT

1. Incorporation. This Addendum is incorporated into and forms a part of the above-referenced Lease, and to the extent the terms hereof conflict or are inconsistent with the terms of the Lease the terms hereof shall control.

2. Tenant Improvements. Landlord, at Landlord's sole cost and expense, hereby agrees to construct and/or install the following tenant improvements in the Demised Premises (the "Tenant Improvements"):

2.(a) Second (2nd) and Sixth (6th) Floors. The configuration of the second (2nd) and sixth (6th) floors shall remain, and be accepted by Tenant, in an "as is" condition. Landlord shall, however, install new wall covering, recarpet all of such space, repaint all of such space, and replace the ceiling tiles therein, all in accordance with the specifications set forth in Exhibit B hereto. Otherwise, Tenant accept such space in an "as is" condition.

2.(b) First (1st) and Fifth (5th) Floors. Landlord shall reconfigure the first (1st) and fifth (5th) floors, and construct and/or install tenant improvements therein (including demolition) substantially in accordance with the specifications (as to level of finish and quantity) attached hereto as Exhibit B ("as built" specifications for existing second floor of the Building) and a space plan to be developed by Tenant subject to Landlord's reasonable approval. Tenant may hire a space planner, at Landlord's expense, to assist it in developing such space plan. Such plan is to be in accord with all applicable codes, including travel distance and means of egress requirements. Landlord shall prepare construction drawings based on Tenant's space plan subject to Tenant's approval which shall not be unreasonably withheld. Tenant may elect to retain the raised floor on the fifth floor, in which case Tenant shall be responsible for any net incremental costs necessary to accommodate such raised floor. Installation and construction of the Tenant Improvements shall begin promptly after Tenant has completed moving its data processing operations into the file Data Center. The parties anticipate that Tenant will have completed such move by May 15, 1992, and acknowledge that if Substantial Completion of the Data Center (as defined in Exhibit G to the Data Center Lease) occurs after November 1, 1991, completion of such move will occur correspondingly later than May 15, 1992. The schedule for installation of Tenant improvements may be changed by the mutual written agreement of the parties. While the Tenant Improvements are being installed or constructed, and until Substantial Completion of the Tenant Improvements (as defined below), Tenant shall have the option to (i) maintain all or any part of its operations in the Demised Premises, with Rent and Operating Expenses abated for any portion of the Demised Premises which Tenant is unable to reasonably occupy for the conduct of its operations therein, until Substantial Completion (as defined below) of such portion, which option shall include the option to occupy the fourth floor of the Building, and to pay Rent and Operating Expenses for such fourth floor space at the rate payable pursuant to the prior lease between Landlord and Tenant for space in the Building (the " ^** Lease"), until Substantial Completion of the Tenant Improvements on the fifth floor of the Building; or (ii) for all or any part of its operations, as reasonably necessary for Tenant to continue the efficient functioning of its operations, occupy similar space, which if available, shall be provided by Landlord and shall be within or as close as reasonably possible to the

^**	Omitted pursuant to a confidential treatment request. The confidential portion has been filed separately with the SEC.

Building in space available in buildings owned by the Landlord, and to pay Rent and Operating Expenses to Landlord as if Tenant were occupying the Demised Premises. "Substantial Completion" of all or any portion of the Tenant Improvements shall mean:

(i) that portion of the Tenant Improvements is substantially complete in accordance with the specifications set forth in the space plan and construction documents approved by the Parties, provided, however, that long-lead items and punchlist items (which shall be deemed to be minor items of trim, decorations and finish, and work and materials installed but rejected by Tenant) need not have been completed, provided that such long-lead items and punchlist items do not (A) materially interfere with or adversely affect the comfortable use and occupancy of that portion of the Demised Premises by Tenant, (B) violate, in any respect, any applicable code or (C) cause that portion of the Demised Premises not to qualify for a nonresidential use permit;

(ii) that portion of the Tenant Improvements is substantially free of construction debris and clean; and

(iii) Landlord's architect has inspected that portion of the Tenant Improvements and delivered to Landlord and Tenant its certificate certifying Substantial Completion of that portion of the Tenant Improvements.

In the event that Tenant desires improvements other than as set forth hereinabove, then, subject to Landlord's approval, such approval not to be unreasonably withheld, conditioned or delayed, Landlord or Tenant, at Tenant's option, shall construct and/or install the same at Tenant's sole cost and expense, provided that Tenant's obligations to pay rent hereunder with respect to the portion of the Demised Premises affected by such additional improvements or modifications shall not be further delayed or abated during the time necessary for their installation or construction.

Notwithstanding anything to the contrary in the ^** Lease, Tenant shall have no obligation to restore the fourth floor of the Building at the expiration of the ^** Lease, and shall surrender it to Landlord at the expiration of the ^** Lease or at the end of any temporary rental pursuant to this Section 2, whichever is later, in good condition, ordinary wear and tear excepted, provided that Tenant shall not be required to remove any of Tenant's Improvements.

3. Real Estate Taxes and Operating Expenses.

3.(a) Additional Rent. In addition to the payments of Rent described in Section 1.1 of the Lease, Tenant shall be responsible for, and hereby agrees to pay to Landlord, the following in the form of additional rent: (i) Tenant's Pro Rata Share (as hereinafter defined) of Real Estate Taxes (as hereinafter defined) applicable to each Lease Year (as hereinafter defined) of the Term; and (ii) Tenant's Pro Rata Share of Operating Expenses (as hereinafter defined) applicable to each Lease Year of the Term, where, for purposes hereof,

(1) "Pro Rata Share" shall mean and refer to fifty-eight percent (58%), representing the ratio that the total number of square feet of net rentable area within the Demised Premises bears to the total number of square feet of net rentable area contained within the Building; and

^**	Omitted pursuant to a confidential treatment request. The confidential portion has been filed separately with the SEC.

(2) "Real Estate Taxes" shall, subject to Section 3.(b) below, mean and refer to any form of real estate tax or assessment, general, special, ordinary or extraordinary, and any license fee, commercial rental tax, improvement bond or bonds, levy or tax (other than inheritance, income or estate taxes) imposed on the Building and the land on which it stands (including the land devoted to Tenant's Parking and Ancillary Facilities, provided that the Real Estate Taxes allocated to Tenant in respect of parking off the ^**, shall be prorated equitably considering other uses of those properties) by any authority having the direct or indirect power to tax, including any city, county, state or federal government, or any school, agricultural, sanitary, fire, street, drainage, transportation or other improvement district thereof, assessed against any legal or equitable interest of Landlord in the Building, assessed against Landlord's right to Rent or other income therefrom, and assessed against Landlord's business of leasing the Demised Premises. The term Real Estate Tax shall not include income taxes of any kind, unless such taxes replace real estate taxes, nor shall it include any costs of any improvements made by Landlord pursuant to a requirement of any public authority imposed as a condition for any approvals required in connection with the development of the Building or any rezoning of the Building site nor to taxes attributable to such improvements to the extent such improvements are located off-site; and

(3) "Operating Expenses" shall mean and refer to all direct costs of operation and maintenance as determined by generally accepted accounting principles consistently applied and shall include the following costs by-way of illustration, but not limitation, subject to Section 3.(b) below: gross receipt taxes (whether assessed against the Landlord or assessed against the Tenant and collected by the Landlord, or both), water and sewer charges, insurance premiums, utilities, janitorial services, labor, including direct labor overhead, a management fee equal to three percent (3%) of the gross receipts related to the Building, air conditioning and heating, elevator maintenance, supplies, and costs and upkeep of all Parking and Common Areas. "Operating Expenses" shall not include (i) depreciation on the Building or equipment therein, (ii) loan payments (including interest), (iii) executive salaries and other compensation to executives, (iv) brokerage commissions and other expenses incurred in procuring tenants for the Building, (v) capital expenditures (except amortization, with interest, of any such expenditures to the extent they reduce operating expenses), (vi) consulting costs and expenses paid by Landlord except to the extent that they relate to improved management and operation of the Building, (vii) costs directly resulting from Landlord's gross negligence or willful misconduct, (viii) costs for which Landlord is reimbursed by insurance, (ix) legal expenses incurred in connection with lease negotiations, (x) costs or expenses incurred in connection with enforcing any obligation of the Tenant (other than routine enforcement as a part of general property management) or of any other tenant, (xi) costs or fees related to the defense of Landlord's title to the property of which the Demised Premises is a part, (xii) any cost or expense related to constructing tenant improvements or providing other tenant concessions in the Building in accordance with the terms of any lease, (xiii) costs and expenses which are directly and completely reimbursed to Landlord by other tenants (other than as a part of the operating expense pass-through section of such tenant's lease), (xiv) costs incurred due to the violation by Landlord or any tenant other than Tenant of any term, covenant or condition of any lease, law, or governmental regulation and (xv) advertising expenses; and

(4) "Lease Year" shall mean and refer to the calendar year, provided that in the first and last Lease Year, Operating Expenses and Real Estate taxes shall be prorated to

^**	Omitted pursuant to a confidential treatment request. The confidential portion has been filed separately with the SEC.

reflect the portion of the calendar year during which additional rent hereunder is payable. For the sake of clarity, the first Lease year commences May 15, 1992 and ends December 31, 1992.

3.(b) Non-Duplicative Rights and Obligations. Landlord and Tenant acknowledge that they have entered into the Data Center Lease simultaneously herewith. Both the ^** and the Data Center are situated on the Site. Therefore, the terms of this Lease and of the Data Center Lease, read together, purport to encumber the same land twice and grant and subject Landlord and Tenant to duplicative rights and obligations with respect to the Land on which the ^** and the Data Center are located. Landlord and Tenant hereby agree that notwithstanding any other provisions of this Lease and the Data Center Lease, for so long as (a) both this Lease and the Data Center Lease remain in full force and effect, and (b) VISA U.S.A. INC. is the Tenant under both this Lease and the Data Center Lease, to the extent either Landlord or Tenant is subjected to liability for the same expense or obligation with respect to the land, or granted an entitlement to some benefit or right with respect to the land, twice due to the fact that such right or liability is recited in both of such leases, such leases shall instead be construed to subject such party to such liability, and to grant such party such benefit or right, but once. Notwithstanding the foregoing, it is expressly agreed, however, that Landlord and Tenant intend that Tenant be obligated to pay the Rent reserved in both such leases and to perform each and every other monetary obligation and non-monetary obligation (other than with respect to the land) of Tenant with respect to the ^** and the Data Center set forth in this Lease and in the Data Center Lease.

3.(c) Estimate and Reconciliation. Tenant shall initially make monthly payments of additional rent hereunder based upon an estimate of Real Estate Taxes and Operating Expenses equaling a rate of Six and 50/100 Dollars ($6.50) per square foot of net rentable area per annum, yielding a monthly payment of Twenty-Four Thousand Two Hundred Sixty-Six and 67/100 Dollars ($24,266.67) per month, payable in advance on the first (1st) day of every month during the first (1st) Lease Year, and continuing until an estimate is made for use during the second (2nd) Lease Year as provided herein below. The first (1st) such installment, however, shall be made on the first (1st) day of the Term with respect to the one-half (1/2) month commencing on May 15, 1992 and continuing through May 31, 1992, and shall equal Twelve Thousand One Hundred Thirty-Three and 33/100 Dollars ($12,133.33). After the end of the first (1st) Lease Year, Landlord shall determine Tenant's actual pro rata share of Real Estate Taxes and Operating Expenses for the first (1st) Lease Year and,

(i) if the estimate has resulted in an overpayment by Tenant, then the amount of such overpayment shall be credited against future installments of additional rent due during the Term, and

(ii) if the estimate has resulted in an underpayment by Tenant, then the amount of such underpayment shall be payable in a lump sum with the next installment payment. With respect to the then current Lease Year an amount equal to one hundred ten percent (110%) of the actual Real Estate Taxes and Operating Expenses incurred during the preceding Lease Year, adjusted pro rata to reflect a twelve (12) month Lease Year, shall be used as the basis upon which to determine the amount of the monthly installment payments for the then current Lease Year which such estimate shall continue in effect during such Lease Year, and until the estimate for the next Lease Year is computed as provided herein. Tenant shall then pay to Landlord any excess of the estimated payments due during the then current Lease Year over the amounts of such payments actually made by Tenant during such Lease Year based upon the first (1st) Lease

^**	Omitted pursuant to a confidential treatment request. The confidential portion has been filed separately with the SEC.

Year's estimate, or Landlord shall credit to Tenant's estimated payments due for the remainder of the then current Lease Year the amount by which the amounts actually paid by Tenant during such Lease Year exceeded the estimated payments due. The foregoing reconciliation and estimate adjustment process shall be repeated after the end of each Lease Year. It is agreed that at the end of the fifth (5th) Lease Year, Landlord and Tenant shall review the history of estimated Real Estate Taxes and Operating Expenses (based upon the ten percent (10%) increase assumption) as compared with the actual increases. Then the ten percent (10%) increase assumption shall be replaced by the actual average percentage increase during such five (5) year period, rounded upwards to the nearest full percentage.

After the end of the Term a final reconciliation shall be made, and Tenant shall pay to Landlord the amount of any underpayments, or Landlord shall pay to Tenant the amount of any overpayments, as applicable.

Each statement provided by Landlord shall be conclusive and binding upon Tenant unless, within sixty (60) days after receipt thereof, Tenant shall notify Landlord that it disputes the correctness of such statement, specifying the respects in which the statement is claimed to be incorrect.

Tenant shall then have the right to demand that Landlord provide, at Tenant's expense, an audit of its books and records relating to the statement. Pending resolution of the dispute, Tenant shall pay the amount due, as set forth in the disputed statement, but such payment shall be without prejudice to Tenant's position.

3.(d) Contest of Real Estate Tax Assessment. If Tenant requests and Landlord refuses to contest Real Estate Taxes, and to the extent that Real Estate Taxes are separately assessed against the Building (including the Data Center Building), Tenant shall have the right, at its sole expense, to contest the amount or validity, in whole or in part, of any Real Estate Taxes or personal property taxes by appropriate proceedings diligently conducted in good faith, only after paying such tax or posting such security as Landlord may reasonably require in order to protect the Demised Premises against loss or forfeiture and otherwise complying with any payment, bonding or other requirements of ^**, Virginia. Upon the termination of any such proceedings, Tenant shall pay the amount of such tax or part of such tax as finally determined, the payment of which may have been deferred during the prosecution of such proceedings, together with any costs, fees, interest, penalties, or other related liabilities. Landlord shall not be required to join in any such contest or proceedings unless the provisions of any law or regulations then in effect require that such proceedings be brought by or in the name of Landlord. In that event, Landlord shall join in such proceedings or permit them to be brought in its name; however, Landlord shall not be subjected to any liability for the payment of any costs or expenses in connection with any such contest or proceedings, and Tenant shall indemnify Landlord against and save Landlord harmless from any such costs and expenses. Notwithstanding the preceding sentence, Landlord shall assist Tenant, at Tenant's expense, in such contest in any way reasonably requested by Tenant.

4. Base Rent Escalation. On the first (1st) anniversary date of the Commencement Date of the Term, and on each anniversary date thereafter during the Term (each of such dates being hereinafter referred to as an "Adjustment Date"), the Rent payable pursuant to Section I.1 shall be increased by an amount equal to the product of (i) the Rent in effect during the month immediately prior to the Adjustment Date then at hand (disregarding any rental abatement then in effect), and (ii) two percent (2%). The Rent, as adjusted, shall be due and payable as of such

^**	Omitted pursuant to a confidential treatment request. The confidential portion has been filed separately with the SEC.

Adjustment Date and on the first (1st) day of each month thereafter until the next Adjustment Date or the end or sooner termination of the Term, whichever is applicable.

5. Renewal Option.

5.(a) Multiple. In the event that Tenant has any multiple options to extend or renew this Lease, a later option cannot be exercised unless the prior option to extend or renew this Lease has been so exercised.

5.(b) Default. Tenant shall have no right to exercise any option, notwithstanding any language in the grant of the option to the contrary, while Tenant is in default hereunder, except that Tenant may exercise such option within the period provided by 5(c) below, which exercise shall not take effect if Tenant fails to cure such default within the period provided in Section 10.

5.(c) Lease Extension. Landlord hereby grants to Tenant the right and option to extend the Term for either, at Tenant's sole option,

(i) two (2) consecutive five (5) year extension terms, or

(ii) one (1) ten (10) year extension term.

Each such extension option may only be exercised by written notice declaring Tenant's election to exercise the extension option given on or before the later to occur of:

(i) twelve (12) months prior to the expiration of the Term preceding such extension term, or

(ii) thirty (30) days after receipt of a written notice from Landlord specifying the expiration date of the option notice period.

All of the terms, covenants and conditions of this Lease shall apply during such extension terms, except that the terms hereof relating to the construction of tenant improvements, and any other terms hereof which, by their very nature, would only be applicable during or prior to the initial term, shall be inapplicable, and the Rent payable for the renewal term(s) in accordance with Section I.1 of this Lease shall be as follows:

(i) the base rent shall be increased to Nineteen and 55/100 Dollars ($19.55) per square foot per annum at the beginning of the first (1st) year of the first (1st) five (5) year extension term, or first (1st) year of the ten (10) year extension term, as applicable, and shall then escalate each year as provided in Section 4 of this Addendum until the end of the particular extension term; and

(ii) in the event that Tenant, having previously exercised its first (1st) five- (5) year extension option, then exercises the second (2nd) five- (5) year extension option, the base rent shall be further increased to Twenty-Four and 95/100 Dollars ($24.95) per square foot per annum at the beginning of the first (1st) year of such second (2nd) five (5) year extension term, and shall thereafter escalate each year as provided in Section 4 of this Addendum until the end of such second (2nd) five (5) year extension term.

6. Insurance.

6.(a) Landlord's Liability Insurance. Landlord shall obtain and keep in force during the Term a policy of commercial general liability insurance naming Tenant as an additional insured,

insuring against any liability arising out of the use, occupancy or maintenance of the Demised Premises and all areas appurtenant thereto. Such insurance shall, together with excess umbrella liability coverage, be a combined single limit policy in an amount not less than Five Million Dollars ($5,000,000), written on an occurrence basis.

6.(b) Landlord's Property Insurance. Landlord shall obtain and keep in force during the Term a policy or policies of insurance covering loss or damage to the Building, in the amount of the full replacement value thereof, as the same may exist from time to time against "all perils" of direct physical damage or comparable coverage as then customary in the insurance industry for comparable property. Said insurance policy or policies shall provide for payment of loss thereunder to Landlord and any Lenders (if such Lenders have been made known to the insuring party) as their interests may appear.

6.(c) Insurance To Be Procured by Tenant. Tenant, at Tenant's sole cost and expense, shall obtain and maintain in effect at all times during the Term, policies providing for the following coverage:

(i) Property Insurance. Policies of insurance covering Tenant's fixtures and equipment installed and located in the Demised Premises, and in addition thereto, covering all of the furnishings, merchandise and other contents in the Demised Premises, for the full replacement value of said items. Coverage should at least insure against any and "all perils" of direct physical damage or comparable coverage as then customary under insurance industry practice in the Commonwealth of Virginia, together with insurance against vandalism, malicious mischief and sprinkler leakage or other sprinkler damage. Any and all proceeds of such insurance, so long as the Lease shall remain in effect, shall be used to the extent necessary to repair or replace or pay for the items so insured.

(ii) Liability Insurance. A policy of commercial general liability insurance, naming Landlord and Landlord's First Mortgage Lender as additional insureds, protecting against bodily injury, property damage or any personal liability occasioned by an occurrence on or about any part of the property, the Demised Premises or appurtenances thereto, and containing contractual liability coverage, with such policies together with excess umbrella liability coverage, to be in the minimum amount of Five Million and No/100 Dollars ($5,000,000.00) per occurrence. In the event that it becomes customary for a significant number of tenants of commercial office buildings in the area to be required to provide liability insurance policies to their landlords with coverage limits higher than the foregoing limits, then Tenant shall be required on demand of Landlord to obtain insurance policies the limits of which are not less than the then customary limits.

(iii) Tenant's Worker's Compensation Insurance. Tenant shall, during the entire Term, keep in full force and effect, worker's compensation or similar insurance affording statutory coverage and containing statutory limits as required under the local worker's compensation or similar statutes.

6.(d) Insurance Policies. All insurance policies herein to be procured by either party shall (i) be issued by good and solvent insurance companies licensed to do business in the Commonwealth of Virginia having a Best's Rating of AX or better, (ii) be written as primary policy coverage and not contributing with or in excess of any coverage which the other party

hereto may carry, and (iii) insure and name respectively Tenant or Landlord as an additional insured as their respective interests may appear; all such policies shall contain a provision that although respectively Tenant or Landlord and Landlord's First Mortgage Lender are named as additional insureds, Tenant, Landlord and such First Mortgage Lender shall nevertheless be entitled to recover under said policies for any loss, injury or damage to it or its servants, agents and employees by reason of the act or negligence of Landlord or Tenant as applicable. Neither the issuance of any insurance policy required hereunder, nor the minimum limits specified herein with respect to Landlord's or Tenant's insurance coverage, shall be deemed to limit or restrict in any way Landlord's or Tenant's liability arising under or out of this Lease. With respect to each and every one of the insurance policies herein required to be procured by Landlord or Tenant, Landlord or Tenant shall deliver to the other party true copies of each such policy or modifications in force at the commencement of the lease and thereafter upon the other party's demand therefor. Any insurance required to be carried hereunder may be carried under a blanket policy covering the Demised Premises and other locations of the party. Each and every insurance policy required to be carried hereunder by or on behalf of a party shall provide (and any certificate evidencing the existence of each such insurance policy shall certify) that, unless the other party shall first have been given thirty (30) days prior written notice thereof: (i) such insurance policy shall not be cancelled and shall continue in full force and effect, (ii) the insurance carrier shall not fail to renew such insurance policy, and (iii) no material changes may be made in such insurance policy. The term "insurance policy" as used herein shall be deemed to include any extensions or renewals of such insurance policy. In the event that Tenant shall fail promptly to furnish any insurance coverage hereunder required to be procured by Tenant, and such failure continues despite Landlord's informal notice to Tenant, Landlord, at its sole option, shall have the right to obtain the same and pay the premium therefor for a period not exceeding one (1) year in each instance, and the premium so paid by Landlord together with an administrative fee of fifteen percent (15%), shall be immediately payable by Tenant to Landlord as additional rent, provided that if Tenant provides evidence of such coverage to Landlord, Landlord shall cancel such coverage obtained by Landlord and credit Tenant the amount of premium, if any, refunded to Landlord, less an administrative charge of fifteen percent (15%) of such refund.

6.(e) Waiver of Subrogation. Tenant and Landlord each hereby release and relieve each other, and waive their entire right to recovery against, the other for loss or damage insured by the policies required herein or any other policies actually held by either Tenant or Landlord, whether due to the negligence respectively, of Landlord or Tenant or their agents, employees, contractors or invitees. Tenant and Landlord shall, upon obtaining the policies of insurance required hereunder, give notice to the insurance carrier or carriers that the foregoing mutual waiver is contained in this Lease and shall use their best efforts to procure the consent of such carrier or carriers to the foregoing mutual waiver and shall cause all of the policies to be procured hereunder to contain a waiver of subrogation endorsement. If such endorsement cannot be obtained at a commercially reasonable expense, this Section 6 shall be deemed null and void with respect to claims covered by the insurance for which such waiver cannot be obtained. Such waiver shall be effective upon receipt of such carriers' consent thereto as well as to the waiver of subrogation endorsement.

6.(f) Insurance Requirements. Tenant shall not do or permit to be done any act or thing upon the Demised Premises that will invalidate or be in conflict with fire insurance policies

covering the property or any part thereof, including all Common Areas, or fixtures and property therein, or any other insurance policies or coverage referred to above in this Section 6; and Tenant shall promptly comply with all rules, orders, regulations, or requirements, of the Insurance Services Office having jurisdiction, or any similar body, in the case of such fire insurance policies, and shall not do, or permit anything to be done, in or upon the Demised Premises, or bring or keep anything therein, which shall increase the rate of fire insurance on the property or on any property, including all Common Areas, located therein, or increase the rate or rates of any other insurance referred to hereinabove applicable to the property or any portion thereof. If by reason of failure of Tenant to comply with the provisions of this Section 6, the fire insurance rate, or the rate or rates of any other insurance coverage referred to above, shall at any time be higher than it otherwise would be, and if Landlord at such time is obligated to, or has elected to, obtain and maintain in effect any such insurance coverage, then Tenant shall reimburse Landlord on demand as additional rent for that part of all premiums for any insurance coverage that shall have been charged because of such violation by Tenant and which Landlord shall have paid on account of an increase in the rate or rates in its own policies of insurance.

7. Notice to Lender; Cure by Lender. In the event of any Landlord Default hereunder, Tenant shall, prior to taking any action to remedy such Landlord Default or to cancel this Lease or any other action in connection therewith, send to The Prudential Insurance Company of America ("First Mortgage Lender"), 1100 15th Street, N.W., Suite 400, Washington, D.C. 20005, ATTN: Director�Real Estate Finance (or a successor First Mortgage Lender of which Landlord has given notice to Tenant), with a copy to the attention of the Regional Counsel at that same address, a notice pursuant to Section IV specifying the Landlord Default, whereupon such First Mortgage Lender shall have the right, but not the obligation, to cure such Landlord Default on behalf of Landlord within the time period provided herein for Landlord's cure of such Landlord Default, which cure shall be accepted by Tenant. Tenant shall have no right to take any other action as a result of any Landlord Default unless and until Tenant complies with the provisions of this Section 7.

8. Estoppel Certificates. Tenant shall, from time to time, within thirty (30) days after request from Landlord, or from any Lender of Landlord, or entity which may be a prospective purchaser of the property of which the Demised Premises are a part, execute, acknowledge and deliver in recordable form a certificate certifying, to the extent true, that this Lease is in full force and effect and unmodified (or, if there have been modifications, that the same is in full force and effect as modified and stating the modifications); that the Term has commenced and the full amount of Rent then accruing hereunder, the dates to which the Rent has been paid; that Tenant has accepted possession of the Demised Premises and that any improvements required by the terms of this Lease to be made by Landlord have been completed to the satisfaction of Tenant; the amount, if any, that Tenant has paid to Landlord as a security deposit; that no Rent under this Lease has been paid more than thirty (30) days in advance of its due date; that the address for notices to be sent to Tenant is as set forth in this Lease (or has been changed by notice duly given and is as set forth in the certificate); that Tenant, as of the date of such certificate, has no charge, lien, or claim of offset under this Lease or otherwise against Rent or other charges due or to become due hereunder; that, to the knowledge of Tenant, Landlord is not then in default under the terms of this Lease; and such other matters as may be reasonably requested by Landlord or any Lender or prospective purchaser of Landlord. Any such certificate may be relied upon by Landlord, or any Lender or prospective purchaser of Landlord. In the

event that Tenant fails to provide Landlord with an estoppel certificate as described and within the time period provided hereinabove, Landlord is hereby appointed Tenant's attorney-in-fact for the purpose of executing such estoppel certificate and delivering the same to any Lender or prospective purchaser of Landlord, which appointment is coupled with an interest and is therefore irrevocable.

9. Computation of Real Estate Taxes and Operating Expenses. In the event that the Building is not fully occupied during any Lease Year, an adjustment shall be made in computing Real Estate Taxes and Operating Expenses for such year so that the costs shall be computed for such Lease Year as though the Building had been 100% occupied during such Lease Year. Landlord shall be responsible for the share of Real Estate Taxes and Operating Expenses attributable to any unoccupied portion of the Building.

10. Notice; Cure. Notwithstanding the provisions of Section I.6 of this Lease, Tenant shall not be in default under this Lease, thereby entitling Landlord to exercise the rights and remedies set forth therein, until such time as Landlord shall have provided Tenant with written notice of Tenant's nonpayment or other failure to comply with any of the terms, covenants and conditions hereof, and afforded Tenant with the following periods of time within which to effect a cure:

10.(a) With respect to a monetary default, ten (10) business days; and

10.(b) With respect to a non-monetary default, thirty (30) days; provided, however, in the event that such a non-monetary failure is not susceptible of being cured by the exercise of due diligence within thirty (30) days, but is susceptible of being cured with the passage of additional time, the time for curing the failure shall be extended for such time as may be necessary to cure the failure by the exercise by Tenant of all due diligence, provided Tenant commences promptly and thereafter at all times diligently proceeds to cure the failure, and further provided that such period of time shall not be so extended as to subject Landlord to any liability, loss or penalty or place Landlord in default under any obligations to third parties, including, without limitation, other tenants and lenders.

10.(c) In the event that Tenant fails to pay Rent or any other payment required hereunder when due, and Landlord shall have provided Tenant with a default notice twice during any twelve (12) month period, then during the remainder of such twelve (12) month period any installment of Rent, or any other payment required hereunder, which is not paid when due shall result in an automatic assessment of a late charge of five percent (5%) of the amount overdue. In the event that Tenant fails to comply with any other term, covenant or condition of this Lease twice during a twelve month period, and Landlord has provided Tenant with written notices of such failures, then the Tenant shall not thereafter during the subsequent twelve (12) month period be entitled to a notice from Landlord nor to a cure period with respect to any future failure of Tenant to comply with such term, covenant or condition of this Lease.

11. Casualty.

11.(a) Determination to Rebuild. If the Building is damaged or destroyed by any casualty to the extent that

(1) the entire Building is damaged or destroyed and such damage or destruction cannot be repaired within three hundred sixty (360) days after the date of such damage or destruction, or

(2) a portion of the Building is damaged by such a casualty and, as a result thereof, Tenant is unable to make any use of the Demised Premises for the operation of its business in accordance with Section II.A of this Lease, then either Landlord or Tenant shall have the right to terminate this Lease as hereinafter provided. If such casualty occurs within three (3) years prior to the end of the Term or any extension of the Term, and (1) repair of such damage or destruction would not be economically feasible, or (2) proceeds from insurance remaining after any required payment to any Lender of Landlord are insufficient to repair such damage or destruction, then Tenant shall have the right to terminate this Lease, and Landlord shall have the right to terminate this Lease unless Tenant agrees to renew this Lease so that the term of this Lease will last at least as long as is required by a prospective Lender of Landlord as a condition of financing such repair, if Tenant does so agree, then Landlord shall rebuild the Building regardless of the availability of insurance proceeds after any required payment to any Lender of Landlord. Within ten (10) days after the occurrence of any such casualty, damage or destruction, Landlord and Tenant shall attempt to agree upon whether such casualty falls within any one or more of the categories hereinabove described. In the event that Landlord and Tenant are unable to so agree, then the determination shall be made by an independent third party architect selected by Tenant, subject to Landlord's approval, which approval shall not be unreasonably withheld, conditioned or delayed. Such architect shall be instructed to make a determination within thirty (30) days after the expiration of the foregoing ten (10) day period. In the event that Landlord and Tenant agree, or the architect determines, that the casualty falls within one or more of the categories set forth hereinabove, then, within ten (10) days next succeeding such determination or agreement, a party having the right to terminate this Lease may exercise that right by written notice to the other. In such event, all insurance proceeds attributable to the Building shall be paid to Landlord, subject, however, to the rights of any Lenders. In the event that this Lease is not so terminated, then Landlord shall proceed with due diligence to restore the Building.

11.(b) Rent Abatement; Rebuilding; Force Majeure. In the event of destruction or damage to the Building or the Demised Premises which renders the Demised Premises partially or wholly unusable by Tenant for the operation of its business, but which does not result in termination of this Lease in accordance with Section 11(a), this Lease shall not terminate and Rent shall be abated in proportion to the area of the Demised Premises which cannot be used or occupied by Tenant for the operation of its business (it being understood that such area may be greater than the area destroyed or damaged), as a result of such casualty. Landlord shall in such event, within a reasonable time after the date of such destruction or damage, subject to Force Majeure (as defined below), restore the Building to substantially the same condition as prior to such partial damage or destruction. In no event shall Rent abate or shall any termination of this Lease occur if damage to or destruction of the Demised Premises is the result of the negligence or willful act of Tenant, or Tenant's agents, employees, representatives, contractors, successors or assigns, licensees or invitees. As used in this Lease, "Force Majeure" shall mean acts of God; inclement weather; explosions; sabotage; riots; civil commotions; acts of war; results of any warfare or warlike conditions; fire or other casualty; energy shortages beyond the reasonable control of the parties hereto; governmental acts and omissions; labor strikes in which they are

directly involved, provided that the parties hereto have made reasonable good faith efforts to minimize the effects of such Force Majeure.

11.(c) Liability. Landlord shall have no liability to Tenant for inconvenience, loss of business or annoyance arising from any repair of any portion of the Demised Premises, except as otherwise specifically provided in this Lease. Landlord shall use all reasonable efforts to minimize annoyance and inconvenience to Tenant caused by any such repair activities, but Landlord shall not be required to confine repair activity to most non-business hours.

11.(d) Vacation; Survival. In the event of termination of this Lease as provided herein, then all Rent shall be apportioned and paid to the date on which Tenant's use of the Demised Premises ceases or the date of such damage, whichever last occurs, and Tenant shall vacate the Demised Premises as soon as is reasonably possible, considering the nature of the work required in connection therewith; provided, however, that those provisions of this Lease which are intended to coyer matters of termination and the period thereafter shall survive the termination hereof.

12. Assignment and Subletting.

12.(a) Consent. Tenant shall not voluntarily or by operation of law assign, mortgage or encumber all or any part of Tenant's interest in this Lease or in the Demised Premises without Landlord's prior written consent, which Landlord may grant, condition or withhold in Landlord's sole discretion. In addition, Tenant shall not sublet all or a portion of the Demised Premises without Landlord's prior written consent, which shall not be unreasonably withheld, conditioned or delayed, it being agreed that Landlord may reasonably base a refusal to consent upon the reputation, financial condition or business of the proposed sublessee, any restrictions placed upon Landlord by any Lender of Landlord, or upon any contractual restrictions or covenants to which Landlord is bound. Landlord shall respond to Tenant's request for consent hereunder within ten (10) days after the Tenant shall have furnished Landlord with a copy of the proposed assignment, mortgage or encumbrance documents and such other documents relating thereto that Landlord may reasonably require. Tenant shall have no right to assign this Lease, or sublet the Demised Premises, at any time that Tenant is materially in default hereunder.

12.(b) Tenant Affiliate. Notwithstanding the provisions of the above Section 12(a), Tenant may assign or sublet the Demised Premises, or any portion thereof, upon notice to Landlord, but without Landlord's prior written consent, to any corporation or entity which controls, is controlled by or is under common control with Tenant, or to any corporation resulting from the merger or consolidation with Tenant, or to any person or entity which acquires all the assets of Tenant as a going concern of the business that is being conducted on the Demised Premises, provided that said assignee or sublessee assumes, in full, the obligations of Tenant under this Lease, and the net worth of such entity, together with that of Tenant, is equal to or greater than the net worth of Tenant prior to such merger, consolidation, or acquisition. Any such assignment or subletting shall not, in any way, affect or limit the liability of Tenant under the terms of this Lease.

12.(c) No Release of Tenant. Regardless of Landlord's consent, no subletting or assignment shall release Tenant's obligation or alter the primary liability of Tenant to pay the rent and to perform all other obligations to be performed by Tenant hereunder. The acceptance

of Rent by Landlord from any other person shall not be deemed to be a waiver by Landlord of any provision hereof. Consent to one assignment shall not be deemed consent to any subsequent assignment. In the event of default by any assignee of Tenant or any successor of Tenant in the performance of any of the terms hereof, Landlord may proceed directly against Tenant without the necessity of exhausting remedies against said assignee or successor.

13. Alterations, Additions and Improvements.

13.(a) Non-Structural. Tenant shall have the right, without Landlord's prior written consent, to make minor non-structural alterations, additions or improvements to the interior of the Building structure, provided the same do not materially affect the mechanical (including, without limitation, the elevator), electrical or plumbing systems of the Building; provided, however, that any such alterations, additions or improvements shall not be made if the result of such work would decrease the market value of the Demised Premises as measured immediately prior to and after the completion of such work. Any other non-structural alterations, additions, or improvements shall only be made after obtaining Landlord's prior written consent, which shall not be unreasonably withheld, conditioned or delayed. In addition, all contractors and subcontractors performing such work shall be licensed and maintain suitable levels of insurance, Landlord and any Lender of Landlord as additional insureds. Tenant shall ensure that all necessary permits have been issued prior to the commencement of any such work.

13.(b) Structural. Tenant shall have the right to make structural alterations, additions, or improvements to the Demised Premises only with Landlord's prior written consent, which shall not be unreasonably withheld, conditioned or delayed; provided however, that such structural alterations, additions or improvements shall not be made if the result of such work would decrease the market value of the Building as measured immediately prior to and after the completion of such work. Landlord may require that the Tenant provide plans and specifications of the proposed work prior to the Landlord granting consent. In addition, Landlord shall have the right to approve all contractors and subcontractors performing such work and require them to be licensed and to maintain suitable levels of insurance, provided that such approval shall not be unreasonably withheld, conditioned or delayed.

13.(c) Drawings. Any structural alteration, addition or improvement to the Demised Premises that Tenant shall make shall be documented with "as-built" drawings, a copy of which shall be delivered to Landlord upon the completion of such structural alteration, addition or improvement.

13.(d) Liens. Tenant shall pay, when due, all claims for labor or materials furnished or alleged to have been furnished to or for Tenant at or for use in the Demised Premises, which claims are or may be secured by any mechanics' or materialmen's lien against the Demised Premises or any interest therein. Landlord shall have the right to post notices of non-responsibility in or on the Demised Premises as provided by law, and shall also have the right to require Tenant to include such a provision and waiver of liens in any of its contracts which could give rise to such liens. If Tenant shall, in good faith, contest the validity of any such lien, claim or demand, then Tenant shall, at its sole cost and expense, defend itself and Landlord against the same, provided, however, that within ten (10) business days of the filing of any such lien, the Tenant shall cause such lien to be removed of record by payment, bonding, or

otherwise. Landlord may require Tenant to pay Landlord's attorney's fees and costs in participating in such action if Landlord shall decide it is in its best interest to do so.

13.(e) Ownership. Except as provided in Section 13(f) hereof, any alterations, additions or improvements made to the Demised Premises shall become the property of the Landlord and shall remain upon and be surrendered with the Demised Premises at the expiration of the Term. Notwithstanding the provisions of this Section 13(e), Tenant's movable trade fixtures, furnishings and equipment, other than that which is affixed to the Demised Premises so that it cannot be removed without material damage to the Demised Premises, shall remain the property of Tenant and may be removed by Tenant subject to the provisions of Section 13(f).

13.(f) Surrender. On the last day of the Term, or on any sooner termination, as provided herein, Tenant shall surrender the Demised Premises (which shall include for purposes of this surrender provision all structural alterations performed by Tenant as provided in this Section 13) to Landlord in the same condition as at the Commencement Date or (in the case of alterations or Tenant Improvements completed after the Commencement Date) on the date of Substantial Completion of such alterations or Tenant Improvements (as defined in Section 2(b) of this Addendum), ordinary wear and tear excepted, and, at Tenant's sole option, remove or surrender any or all of the alterations performed by Tenant as provided in this Section 13 and Tenant's trade fixtures, furnishings and equipment. Tenant shall repair any damages to the Demised Premises occasioned by the installation or removal of any of the foregoing. Notwithstanding anything to the contrary otherwise stated in this Lease, Tenant shall leave the air lines, power panels, electrical distribution systems, lighting fixtures, space heaters, air conditioning, plumbing and fencing on the Demised Premises in good operating condition.

13.(g) Compliance with Laws; Workmanship. Any alterations, additions or improvements made to the Demised Premises shall be constructed in a good and workmanlike manner, strictly in accordance with all applicable laws, rules, regulations, orders, ordinances, building codes, and board of fire underwriters requirements.

14. Environmental Requirements. Landlord, with regard to its ownership of the Building and its responsibilities set forth in this Lease, and Tenant, with regard to its occupancy of the Demised Premises and its responsibilities set forth in this Lease, shall at all times during the Term be in compliance with any and all applicable federal, state and local laws, rules, regulations, orders, ordinances, and standards, as they may now or hereafter exist, relating in any way to hazardous or toxic substances or other environmental matters, including, without limitation, the Comprehensive Environmental Response, Compensation and Liability Act of 1980, as amended, the Superfund Amendments and Reauthorization Act, the Resource Conservation and Recovery Act, the Toxic Substances Control Act, the Federal Water Pollution Control Act (a/k/a the Clean Water Act), the Clean Air Act, and the ^** Act.

15. Expansion Options.

15.(a) Fourth Floor Space. Tenant may opt to retain the 4th floor of the Building by giving written notice to Landlord on or before March 31, 1992. If Tenant exercises such option, then such space shall become part of the Demised Premises commencing upon the Commencement Date, and this lease shall be amended to reflect such fact and to adjust accordingly Tenant's Pro Rata Share for the purpose of computing Tenant's Pro Rata Share of Operating Expenses and Real Estate Taxes pursuant to Section 3 above. Landlord shall

^**	Omitted pursuant to a confidential treatment request. The confidential portion has been filed separately with the SEC.

construct (including demolition) tenant improvements therein in conformance with the improvements to be installed pursuant to Section 2(b) above, regarding the first and fifth floors, in accordance with a mutually agreeable schedule. If Tenant does not exercise such option on or before March 31, 1992, then the fourth floor shall be considered "expansion space" subject to Tenant's option set forth in Section 15.2 below.

15.(b) Space Available; Exercise. In the event that any space in the Building becomes available for lease after the date hereof including space leased to Tenant in the fourth (4th) floor or the basement of the Building, pursuant to the ^** Lease, Landlord shall so notify Tenant and Tenant shall have the option to lease such space, subject to any renewal rights of others existing as of the date hereof and of which Landlord has notified Tenant in writing. Tenant may exercise such option by giving written notice to Landlord at any time up to fifteen (15) days after Tenant receives written notice from Landlord that Landlord has a Prospective Tenant (as defined herein below) whereupon Landlord and Tenant shall proceed in good faith to negotiate a lease therefor within sixty (60) days after receipt of Tenant's notice. If Landlord and Tenant cannot agree on the rent for such space within thirty (30) days after receipt of Tenant's notice, the rent shall be the Rent Tenant is then paying pursuant to this Lease, but not greater than fair market rent as determined by a real estate broker of Tenant's choice, reasonably approved by Landlord and for a term not longer than the remainder of the term of this Lease, but subject to Tenant's renewal options in Section 5 above. As used in this Section 15, "Prospective Tenant" means a party (i) which has signed a non-binding letter of intent that it will lease the space or (ii) for whose use of the space there has been prepared a second (i.e., revised) space plan or (iii) which has initialed a space plan indicating its agreement to the plan for its use of the space. In the event that (i) Tenant notifies Landlord that it does not desire to lease such space, (ii) Tenant fails to notify Landlord that it desires to lease such space within the time period provided, or (iii) Landlord and Tenant are unable to agree upon terms for such a lease within the sixty- (60-) day negotiation period provided, then Landlord shall again have the right to lease such space to any third party of Landlord's choice, subject to Tenant is continuing option to lease such space in accordance with this Section 15.2. In the event that Landlord does not execute a binding lease with the party identified to Tenant as a Prospective Tenant within 120 days of such notice to Tenant, then Tenant's option pursuant to this Section 15 shall be renewed until fifteen (15) days after Tenant shall have received notice from Landlord of a different Prospective Tenant for such space. From time to time during the Term, at Tenant's request and no more often than once each year, Landlord shall provide Tenant with a schedule of the lease expiration dates and renewal options of other tenants in the Building.

15.(c) Maximum Lease Terms. Landlord shall not enter into any lease of space in the Building, other than with Tenant, for a term of more than five years, including renewal and/or extension options without providing right of refusal at intervals of five years or less to Tenant.

15.(d) ^**. Prior to building any building on the ^** parcel, Landlord shall notify Tenant of its intention to do so and consult with Tenant at such time that Landlord has the opportunity, at Landlord's sole option, to offer that building to Tenant or to provide for Tenant's future potential requirements in the design of such building.

16. Parking. The area which at any particular time during the effective period of this Lease is then being provided as parking for the Building is herein called the "^** Parking Area". Landlord and Tenant are contemporaneously herewith entering into a Lease for a computer facility space to be annexed to the Building, called the "Data Center", and that lease is

^**	Omitted pursuant to a confidential treatment request. The confidential portion has been filed separately with the SEC.

hereinafter called the "Data Center Lease". The parking area provided to Tenant pursuant to the Data Center Lease shall be called the Parking Area�. Tenant currently leases space in the ^** from Landlord pursuant to a lease entered into February 15, 1977, and subsequent amendments thereto, called the " ^** Lease". Under the ^** Lease, Tenant is provided at least 4 parking spaces per 1,000 rentable square feet located adjacent to the ^**. Tenant agrees that commencing with the commencement of construction of the Data Center, the ratio of parking spaces in the Parking Area and the ^** Parking Area to rentable floor area in the Data Center and the ^** may be reduced by Landlord, subject to the following conditions:

16.(a) Minimum Parking Ratio. At no time during which this Lease is in force (including any renewal periods) shall Landlord provide to Tenant less than 2.6 parking spaces per 1,000 square feet of rentable space in the Premises. At no time during which both this Lease and the Data Center Lease are in force shall Landlord provide to Tenant less than 2.6 spaces per each 1,000 rentable square feet demised to Tenant under both this Lease and the Data Center Lease. At the commencement of both said Leases, Landlord and Tenant agree that such minimum number of spaces for the combined leases shall be 275 spaces. In addition to such spaces allocated hereunder to Tenant, Landlord shall reserve the minimum number of spaces for handicap parking required by law adjacent to the handicap access ramp to the Building, plus six spaces reserved for visitors of all tenants or the Building, located adjacent to the front entrance of the Building.

16.(b) Location. Landlord has represented that such minimum number of spaces cannot be provided entirely adjacent to the Building. Landlord shall always provide tenants of the Building and Data Center the maximum number of spaces adjacent to the Building (i.e., on the ^** Parcel) as can reasonably be built as surface parking on that site (except during construction of the Data Center as set forth below). Additionally, Landlord shall develop, solely at Landlord's expense, the maximum number of spaces for surface parking reasonably possible taking into account engineering requirements, on the parcel immediately across ^** , known as the ^** Parcel ("^** Parking Area"). This parking area shall always be included in the Parking Area and the ^** Parking Area until such time if ever, as Landlord constructs a parking structure on the ^** parcel and provides parking spaces to Tenant therein in accordance with Section 16.3 below. Further, Landlord shall use its best efforts to obtain immediately the agreement of the tenants of the office building located on the ^** Parcel to permit Tenant's employees and invitees to park in the parking area presently serving that building, provided that Tenant and Landlord agree that such ^** Parcel tenants employees and invitees may park in the ^** Parking Area. If and when Landlord constructs a structured parking facility on the ^** Parcel, Landlord may reallocate Tenant's parking spaces from the ^** and/or ^** parcels to such structure in accordance with this Section 16.1. If parking is provided in such structured parking facility to any party or parties other than tenants of the building to be built on the ^** parcel, then Tenant, at its option, may have its parking spaces reallocated from the ^** and/or ^** parcels to such structured parking facility. If and when parking spaces are provided to Tenant in a structured parking facility on the ^** Parcel, and if such structure is situated in such a location that the convenient entry from such parking structure into the Building is the entrance that as of the date hereof constitutes the rear entrance of the Building, then Landlord shall reconstruct at Landlord's sole expense, the rear entrance, such reconstruction

^**	Omitted pursuant to a confidential treatment request. The confidential portion has been filed separately with the SEC.

to be consistent in style and quality with the front entrance to the Building existing as of the date hereof, and subject to Tenant's approval, which approval shall not be unreasonably withheld, conditioned or delayed.

16.(c) Priority Measures. If Tenant shall reasonably determine, at any time during which this Lease or the Data Center Lease is in force, that Tenant's employees and invitees cannot find sufficient parking spaces within the Parking Area or the ^** Parking Area with reasonable convenience, whether because occupancy of the surrounding buildings has increased substantially or because third parties have encroached upon the Parking and ^** Parking Area or for other reasons, then upon Tenant's request, Landlord shall reserve 162 spaces on the ^** Parcel and 113 spaces on the ^** Parcel (or ^** Parcel) for Tenant's exclusive use. Such spaces on both parcels shall be those most immediately adjacent to the Building without, however, displacing the spaces reserved for handicapped and visitor parking. The balance, if any, of the Parking Area or ^** Parking Area shall be provided to Tenant, in common with other tenants of Landlord, on the ^** and ^** parcels. If Landlord shall not have obtained for Tenant parking spaces on the ^** Parcel, then the spaces to be reserved for Tenant thereon shall be reserved for Tenant on the ^** Parcel, provided that such reservation of spaces on the ^** Parcel shall not relieve Landlord of its duty to use its best efforts to obtain such spaces for Tenant on the ^** Parcel.

Alternatively, Landlord may, at its option and expense, erect and maintain a parking structure on the ^** parcel and if Landlord shall have allocated parking spaces therein to Tenant, then, at Tenant's option, reserve such spaces for Tenant's use therein equivalent to the number which are allotted to Tenant above in this Section 16.3 on the ^** and/or ^** Parcels.

Any reservation of spaces for Tenant in the Parking Area and the ^** Parking Area (including the ^** , ^** and/or ^** Parcels as applicable) shall be done initially through signage erected or labeling of spaces at Landlord's expense. In the event that Tenant reasonably determines that signage alone is not effective, then Tenant may control access through the issuance of parking stickers and other reasonable measures and Landlord shall give Tenant all reasonable assistance in enforcing such parking provisions.

^**	Omitted pursuant to a confidential treatment request. The confidential portion has been filed separately with the SEC.

as may be released from the lien hereof from time to time, is sometimes hereinafter referred to as the "Property."

2. Assignor has executed and delivered to Assignee a Modification Agreement and Allonge - Deed of Trust Note, which amends and restates a certain Note Secured by Deed of Trust dated December 17, 1986 (as modified, the "Note"), which Note is in the principal amount of $115,000,000.00, and an Amended and Restated Deed of Trust (Existing Deed of Trust - Existing Collateral) ("Security Instrument") of even date and recorded contemporaneously herewith, securing the obligations of Assignor under the Note and the Security Instrument ("Obligations").

3. Assignor desires to transfer and assign to Assignee all of its right, title and interest in, to and under the leases described in "EXHIBIT B" attached hereto and by this reference incorporated herein, and any and all other leases, subleases, lettings and licenses of or affecting the Property that have been or may hereafter be entered into (collectively, "Leases") and (a) all amendments, extensions, modifications, replacements or renewals thereof, (b) the rents, income and profits due, or to become due thereunder (the "Rents"), and (c) the right to enforce, whether at law or in equity or by any other means, all provisions thereof, including, without limitation, any guarantees of the obligations owed Assignor thereunder.

NOW THEREFORE, for good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, with intent to be legally bound hereby, and as an inducement for the making and extension of the loan evidenced by the Note and secured by the Security Instrument, Assignor hereby grants Assignee its interest in, and transfers, sets over and assigns to Assignee all right, title and interest of Assignor in, to

and under (a) the Leases and all amendments, extensions, modifications, replacements or renewals thereof, and (b) the Rents. This Assignment is intended to be and is an absolute present assignment from Assignor to Assignee and not the mere passage of a security interest or the provision of additional collateral security to Assignor; provided, however, that Assignor shall have a license to collect, retain, use and enjoy, except as hereinafter provided, the Rents accruing by virtue of the "Leases as they respectively become due (�License"), but not in advance of their due date, and to enforce the agreements of the Leases so long as there is no default or breach by Assignor under any of the terms, covenants or provisions of the Obligations, the Note, the Security Instrument or this Assignment; and provided further that upon payment in full of the Obligations, this Assignment shall be released and discharged in accordance with Paragraph 3 hereof.

Assignor further covenants and agrees as follows:

1. Assignee as Creditor of Lessee. Assignee, and not Assignor, shall be the creditor of the lessee under any Lease ("Lessee") in respect of assignments for the benefit of creditors and bankruptcy, reorganization, insolvency, dissolution or receivership proceedings affecting any such Lessee. Assignee, however, shall not be the party obligated to make timely filings of claims in such proceedings or to otherwise pursue creditor's rights therein, and at the option of the Assignee, all such claims and filings shall be made by Assignor under the License granted by Assignee hereunder. Assignee shall have the option once the License has been revoked to apply any monies received by it as such creditor to the reduction of the principal of, if any, or interest on the Obligations, or as otherwise permitted by this Agreement or the Security Instrument.

2. Default Remedies of Assignee. If Assignor defaults on the Obligations, the Security Instrument or this Assignment, and until such default shall have been fully cured, the License of Assignor to collect rents, income and profits shall cease and terminate upon written notice to Assignor. In furtherance thereof, Assignee shall be authorized, but under no obligation, to collect the rents, income and profits arising from the Leases, and (if such default is not cured within any applicable cure period; i.e., if an Event of Default shall have occurred) to enforce performance of any other terms of the Leases including, but not limited to, Assignor's rights to fix or modify rents, sue for possession of the leased premises, relent all or part of the leased premises, and collect all rents, income and profits under such new leases. Assignor shall also pay to Assignee, (i) promptly upon any such default all rent prepayments collected prior to the due date therefore and security or other deposits paid to Assignor pursuant to any Lease assigned hereunder and (ii) promptly upon any default (if such default is not cured within any applicable cure period; i.e., if an Event of Default shall have occurred) all charges for services or facilities or for escalation which have theretofore been paid pursuant to any such Lease to the extent allocable to any period from and after such default. Assignee will, after payment of all proper costs, charges and any damages including, without limitation, those payable pursuant to paragraph 6 hereof, apply the net amount of such rents, income and profits to the sums then due to Assignee under the Obligations. Assignee shall have sole discretion as to the manner in which such net income is applied, the reasonableness of the costs to which it is applied, and the items that will be credited thereby.

3. Termination of Assignment. When Assignor pays Assignee for the full amount of the indebtedness secured by the Security Instrument and this Assignment, and such payment is evidenced by a recorded satisfaction or release of the Security Instrument, this Assignment shall terminate and become void.

4. Notice to Lessee of Assignor's Default. Assignor hereby irrevocably authorizes each Lessee, upon demand and notice from Assignee of Assignor's default under the Obligations, the Security Instrument or this Assignment, to pay all rents, income and profits under the Leases to Assignee. Each Lessee shall have the right to rely upon any such notices of Assignee that Lessee shall pay all rents, income and profits to Assignee, without any obligation to inquire as to the actual existence of the default, notwithstanding any claim of Assignor to the contrary. Assignor shall have no claim against any Lessee for any rents paid by Lessee to Assignee. Upon the curing of all defaults caused by Assignor under the Obligations, the Security Instrument or this Assignment, Assignee shall give each Lessee written notice of such cure and, thereafter, until, further notice from Assignee, the Lessees shall pay the rents, incomes and profits to Assignor.

5. Assignment of Defaulting Assignor's Interest in Lease. If an Event of Default shall have occurred under the Security Instrument or this Assignment, Assignee shall then have the right to assign Assignor's right, title and interest in and to the Leases to any person acquiring title to the Property through foreclosure or otherwise. Such assignee shall not be liable to account to Assignor for the rents, income, and profits thereafter accruing.

6. Indemnification of Assignee. Assignor hereby agrees to indemnify and hold Assignee harmless from any and all claims, liability, loss or damage that Assignee may incur under the Leases or by reason of this Assignment; provided, however, that such indemnification shall not apply to damages which result directly from the willful misconduct or gross negligence of Assignee. Nothing in this paragraph shall be construed to bind Assignee to the performance of any Lease provisions, or to otherwise impose any liability upon Assignee including, without limitation, any liability under covenants of quiet enjoyment in the Leases in the event that any Lessee shall have been joined as party defendant in any action to foreclose the Security Instrument and shall have been barred thereby of all right, title, interest, and equity of redemption in the premises. This Assignment imposes no liability upon Assignee for the operation and maintenance of the premises or for carrying out the terms of any Lease (except as may be herein provided) before Assignee has entered and taken possession of the premises following an Event of Default. Any loss or liability incurred by Assignee, by reason of actual entry and taking possession under any Lease or this Assignment or in the defense of any claims shall, at Assignee's request, be reimbursed by Assignor. Such reimbursement shall include interest at the rate (including, without limitation, any applicable Default Rate) set forth in Note, costs, expenses and reasonable attorneys' fees. Assignee may, upon entry and taking of possession, collect the rents, income and profits and apply them to reimbursement for any such loss or liability.

7. Assignor's Possession After Event of Default. If, following an Event of Default under the Security Instrument, Assignor occupies any portion of the Property as a tenant and is not required to surrender such possession hereunder, Assignor shall pay

monthly in advance to Assignee, on Assignee's entry into possession, or to any receiver appointed to collect the Rents, the fair and reasonable value for the use and occupancy of the Property or such part thereof as may be in possession of Assignor. Upon default in any such payment, Assignor shall forthwith vacate and surrender such possession to Assignee or such receiver and, in default thereof, Assignor may be evicted by summary or any other available proceedings or actions.

8. Quality of Assignor's Title to Lease. Assignor represents itself to be the absolute owner of the Leases, with absolute right and title to assign the Leases and the rents, income and profits due or to become due thereunder. Assignor further represents that the Leases are valid and in full force and effect and have not been modified, amended or terminated, or any of the terms and conditions thereof waived, except as stated herein or otherwise disclosed in writing to Assignee; that there are no outstanding assignments or pledges thereof or of the rents, income and profits due or to become due thereunder to anyone other than Assignee; that there are no existing defaults or any state of facts which, with notice or lapse of time, or both, would constitute a default under the provisions thereof on the part of either party, except with respect to the ^** or as otherwise provided in the rent roll furnished by Assignor to Assignee (but such representation and warranty is made as to the best of the Assignor's knowledge, information and belief as to defaults of any tenant); that, to the best of its knowledge, no Lessee has any defense, set-off or counterclaim against Assignor, except as may be expressly permitted by the Lease; that, to best of its knowledge, each Lessee is in possession and paying rent and other charges under its Lease, except as may be expressly permitted by the Lease; and that no rents, income or profits payable thereunder are

^**	Omitted pursuant to a confidential treatment request. The confidential portion has been filed separately with the SEC.

currently subject to or of any anticipation, discount, release, waiver, compromise or other discharge, except as may be expressly permitted by the Lease or as otherwise disclosed in writing to the Assignee.

9. Permitted Lease Terminations and Amendments. Reference is made to Paragraph 20 of the Security Instrument for the rights of the Assignor to modify or terminate Leases without the prior written consent of the Assignee. In the event that any provision of this Assignment requires the consent of the Assignee, then the same procedure outlined in Paragraph 20 of the Security Instrument shall be utilized hereunder.

10. Delivery of Necessary Instruments to Assignee. Assignor shall execute and deliver to Assignee, and hereby irrevocably appoints Assignee, its successors and assigns as its attorney-in-fact to execute and deliver during the term of this Assignment, all further instruments as Assignee may deem necessary to make this Assignment and any further assignment effective. Assignor shall, upon demand, pay to Assignee, or reimburse Assignee for the payment of, any and all costs and expenses (including reasonable attorneys' fees) incurred in connection with the preparation and recording of such instruments.

11. Transfer of Title to Lessee; Cancellation of Lease. Each Lease shall remain in full force and effect, notwithstanding any merger of Assignor's and Lessee's interest thereunder. In the event that any Lease permits cancellation thereof on payment of consideration and said privilege of cancellation is exercised, the payments made or to be made by reason thereof are hereby assigned to Assignee to be applied, at the election of Assignee, to reduce the amount of the principal of the Obligations (without the

imposition of a prepayment penalty) in the inverse order of maturity or to be held in trust by Assignee in interest bearing accounts as further security for the payment of the principal and interest required to be paid by the Obligations.

12. Assignments of Leases. Assignor shall not consent to any Lease assignment or subletting under any Lease covering space within the Property (except in the ordinary course of business in connection with leases of apartments in the ^**) if such consent of the Assignor as landlord is required by the terms of the Lease, nor agree to a subordination of any Lease to any mortgage or other encumbrance now or hereafter affecting the premises without Assignee's prior written consent.

13. Assignor to Ensure Continued Performance Under Leases. Assignor shall not execute any other assignment or pledge of the Leases, of any interest therein, or of any rents payable thereunder. Assignor shall perform all of its covenants as Lessor under the Leases. Assignor shall not consent, without the Assignee's written consent, to any withholding of rent payments by any lessee (a "Lessee") under any Lease covering space within the Property (except in the ordinary course of business in connection with leases of apartments in the ^**). Assignor shall promptly deliver to Assignee copies of any and all notices of default Assignor has sent to any Lessee, except for notices sent to tenants of apartments in the ^**. Assignor shall, upon Assignee's request and at Assignor's expense, enforce all Leases covering space within the Property (except in the ordinary course of business in connection with leases of apartments in the ^**) and all remedies available to Assignor thereunder upon any Lessee's default. Assignor shall deliver to Assignee copies of all papers served in connection with any enforcement proceedings under any Lease (except

^**	Omitted pursuant to a confidential treatment request. The confidential portion has been filed separately with the SEC.

for leases of apartments in the ^**) and shall, if requested by Assignee, consult with Assignee, its agents and attorneys with respect to the conduct thereof; provided that Assignor shall not enter into any settlement of any such proceeding under any Lease covering space within the Property (except for leases of apartments in the ^**) without Assignee's prior written consent.

14. Changes in Obligation Terms. Notwithstanding any variation of the terms of the Obligations and/or the Security Instrument, including any increase or decrease in the principal amount thereof or in the rate of interest payable thereunder or any extension of time for payment thereof or the release of any part of the Property subject to the Security Instrument, the Leases (other than those in connection with released portions of the Property) and the benefits hereby assigned shall continue in favor of Assignee in accordance with the terms of this Assignment.

15. Additions to and Replacement of Obligations. Assignee may take security in addition to the security already given to or for the benefit of Assignee for the payments of the principal, premium and interest required to be paid in or by the Obligations or release such other security, and may release any party primarily or secondarily liable on the Obligations, may grant or make extensions, renewals, modifications or indulgences with respect to the Obligations or the Security Instrument and replacements thereof, which replacements of the Obligations or the Security Instrument may be on the same terms as, or on terms different from, the present terms of the Obligations or the Security Instrument, and may apply any other security thereof held by it to the satisfaction of the Obligations, without prejudice to any of its rights hereunder.

^**	Omitted pursuant to a confidential treatment request. The confidential portion has been filed separately with the SEC.

16. Permitted Leases. Reference is made to Paragraph 20 of the Security Instrument for the rights of the Assignor to enter into Leases without the prior written consent of Assignee. In the event that any provision of this Assignment requires the consent of the Assignee, then the same procedure outlined in Paragraph 20 of the Security Instrument shall be utilized hereunder.

17. Exercise of Assignee's Rights. Assignee's failure to avail itself of any of its rights under this Assignment for any period of time, or at any time or times, shall not constitute a waiver thereof. Assignee's rights and remedies hereunder are cumulative, and not in lieu of, but in addition to, any other rights and remedies Assignee has under the Obligations and the Security Instrument. Assignee's rights and remedies hereunder may be exercised as often as Assignee deems expedient.

18. Cumulative Rights and Remedies. The rights and remedies of Assignee under this Assignment are cumulative and are not in lieu of, but are in addition to, any other rights or remedies which Assignee shall have under the Note, the Security Instrument or any other instrument constituting security for the Obligations, or at law or in equity.

19. Severability. If any term of this Assignment, or the application hereof to any person or set of circumstances, shall to any extent be invalid or unenforceable, the remainder of this Assignment, or the application of such provision or part thereof to

persons or circumstances other than those as to which it is invalid or unenforceable, shall

not be affected thereby, and each term of this Assignment shall be valid and enforceable to the fullest extent consistent with applicable law.

20. Captions. The captions or headings at the beginning of each paragraph hereof are for the convenience of the parties only and are not part� of this Assignment.

W I T N E S S E T H :

WHEREAS, Landlord and Tenant entered into an Office Lease together with an Addendum to Office Lease (collectively, the "Lease") dated April 18, 1991, whereby Landlord agreed to rent, demise and lease to Tenant and Tenant agreed to take, hire and rent from Landlord those premises consisting of the entire 1st, 2nd, 5th and 6th floors ("Original Space") of the building known as the ^** located at ^** ("Building"); and

WHEREAS, it is the desire and intent of the parties hereto to amend the Lease by adding the 4th floor to the Demised Premises, and modifying certain other terms and conditions thereof, all as more particularly set forth below.

NOW, THEREFORE, for and in consideration of the sum of Ten Dollars ($10.00) and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged by the parties hereto, Landlord and Tenant agree as follows:

1. Demised Premises. Effective as of May 15, 1992, Landlord does demise, rent and lease unto Tenant and Tenant does take, rent and hire from Landlord the entire 4th floor of the Building consisting of approximately 11,200 rentable square feet as more particularly shown on the floor plan attached hereto as Exhibit A and incorporated herein by reference.

5. Real Estate Taxes and Operating Expenses. Effective as of May 15, 1992, Tenant's monthly payments of additional rent for estimated Real Estate Taxes and Operating Expenses due under the Lease shall increase to $30,333.33. The aforesaid amount is based upon an estimate of Real Estate Taxes and Operating expenses equaling a rate of $6.50 per square foot of net rentable area of the Original Space and the New Space per annum.

6. Abatement. Provided Tenant has not defaulted in the performance of the terms of the Lease or this Amendment, Landlord will abate the monthly Rent and the additional rent for Real Estate Taxes and Operating Expenses for the New Space only (and not for the Original Space) due for the period commencing May 15, 1992 and continuing until June 30, 1992. No other Rent shall be abated during the Term or any renewal, extension or holdover period.

7. Leasehold Improvements to the New Space.

A. Landlord, at Landlord's sole cost and expense, has caused its architect to prepare a space plan for the improvements to be made to the Demised Premises ("Improvements"), and Landlord has also caused its architect and engineer to prepare contract documents ("Final Plans") for the Improvements.

The foregoing are referred to as "Building Standard Improvements". Any Improvements shown on the Final Plans which are not Building Standard Improvements shall be constructed by Landlord, but Tenant shall be solely responsible for all costs and expenses incurred in connection therewith.

8. Commencement Date for Original Space. Landlord and Tenant acknowledge and confirm that the Commencement Date for the Original Space is May 15, 1992, and the Rent for the Original Space commenced accruing on such date and shall continue to accrue while Landlord completes the improvements to be made thereto.

9. Leasehold Improvements to the Original Space.

A. The ninth (9th) sentence of paragraph 2(b) of the Addendum to Office Lease is hereby deleted in its entirety and the following is inserted in its place and stead:

"While the Tenant Improvements are being installed or constructed, and until Substantial Completion of the Tenant Improvements (as defined below), Landlord shall make good faith efforts to make similar space available for all or any part of Tenant's operations, as reasonably necessary for Tenant to continue efficient functioning of its operations. The similar space shall be as close as reasonably possible to the Building in space available in buildings owned by Landlord. Tenant shall pay Rent and Operating Expenses to Landlord as if Tenant were occupying the Demised Premises."

B. The last paragraph of paragraph 2 of the Addendum to Office Lease regarding surrender of the 4th floor of the Building is hereby deleted in its entirety.

10. Expansion Options. Paragraph 15 (a) of the Addendum to Office Lease is hereby deleted in its entirety, and all references to the fourth (4th) floor contained in paragraph 15 (b) are hereby deleted in their entirety.

Each party agrees to indemnify and hold the other party harmless from and against any and all losses, costs (including, without limitation, court costs and reasonable attorney's fees), liabilities, claims or damages incurred by such other party as a result of a breach of the foregoing representations by the indemnifying party.

12. Data Center Lease. All references to the "^** Lease" contained in the Data Center Lease between Landlord and Tenant dated April 18, 1991 shall mean and refer to the Lease as amended by this Amendment and as further amended from time to time.

13. Defined Terms. Defined terms used in this Amendment shall have the same meaning as set forth in the Lease unless another meaning is provided herein.

14. Ratification. Except as set forth above, the parties hereto expressly ratify and confirm all of the terms and conditions of the Lease which shall remain in full force and effect as to the Demised Premises as defined in this Amendment.

WHEREAS, by letter dated October 4, 2000, Tenant exercised its first (1^st) of two (2) renewal options to extend the Term of the Lease five (5) years, through October 31, 2006; and

WHEREAS, the parties now desire to amend the Lease to extend the Term thereof, and for other purposes, as more particularly set forth herein.

1 Term. The Term of the Lease is hereby extended five (5) years, through October 31, 2011.

2 Rent. Effective as of November 1, 2006, Tenant's monthly "Rent" obligation, as described in Section I.1 of the Lease, shall be increased to One Hundred Sixty-Three Thousand Four Hundred Ninety-One and 11/100 Dollars ($163,491.11) per month.

3 Condition. Tenant agrees to accept the Demised Premises in "as-is" condition for the Term, as hereby extended.

4 Renewal Options. The extension of the Term described in this Fourth Amendment constitutes the second (2^nd) of two (2) renewal options under Section 5 of the Addendum to the Lease,

5 Termination Option. Notwithstanding the extension of the Term pursuant to this Fourth Amendment, Tenant shall have the unilateral right to terminate the Lease on April 30, 2008, or any day thereafter during the Term, as hereby extended, by delivering to Landlord written notice thereof at least twelve (12) months prior to the termination date.

Landlord shall have the right to reconfigure the portion of the ^** located on the ^** Parcel, so long as the number of parking spaces thereon (i.e., 113) remains the same and Tenant's ability to use the ^** is not interrupted. Tenant shall be permitted to park semi-tractor trailers - for the temporary storage and operation of diesel fuel and generators - on the portion of the ^** located immediately adjacent to the. Building, on the north side, but only in the event of an emergency, casualty or other event during which Tenant reasonably requires such capability, provided that Tenant complies with applicable "Environmental Laws" (as defined in the Addendum to the Data Center Lease), and does not unreasonably interfere with other tenants' access to or use of the Demised Premises. Throughout the Term, Landlord shall maintain a stairway from the portion of the ^** located on the ^** Parcel to the portion of the Parking Area located on the Site, and shall provide lighting in the ^** commensurate with the lighting currently provided in the ^**.�
