THIS ASSUMPTION AND ATTORNMENT AGREEMENT (“this Agreement”), is made as of the 31 day of October, 2003, by and between ARCHIPELAGO HOLDINGS, L.L.C., an Illinois limited liability company (“Archipelago”), and MJH XXXXXX LLC, a Delaware limited liability company (“Owner”).

RECITALS

A. Owner and Archipelago have entered into that certain Office Lease of even date herewith (the “Archipelago Lease”), pursuant to which Archipelago has leased from Owner certain office space (the “Archipelago Premises”) on 17^th and 18^th floors of the building located at 000 Xxxxx Xxxxxx Xxxxx, Xxxxxxx, Xxxxxxxx 00000 (the “Building”).

B. Owner (or its predecessors-in-interest) and Xxxxxxxx Analytics, Ltd. (“Xxxxxxxx”) have entered into that certain lease dated as of June 3, 1996, as amended, a copy of which is attached hereto as Exhibit A and incorporated herein by reference (the “Xxxxxxxx Leases”), pursuant to which Xxxxxxxx is leasing certain space in the Building (the “Xxxxxxxx Premises”) which includes a data room comprising approximately eleven thousand nine xxxxxx four (11,904) square feet of rentable area on Lower Level 2 of the Building and known as Suite LL2-005 and on Lower Xxxxx 0 of the building owned by Owner located at 000 Xxxxx Xxxxxx Xxxxx, Xxxxxxx, Xxxxxxxx and known as Suite LL2-34 (collectively, the “LL2 Data Room”) and a data room comprising approximately three thousand (3,000) square feet of rentable area on 20^th floor of the Building as shown on Exhibit D attached hereto and incorporated herein by reference (the “20^th Floor Data Room” and collectively with the LL2 Data Room, the “Data Rooms”).

C. In conjunction with Xxxxxxxx’x lease of the LL2 Data Room pursuant to the Xxxxxxxx Lease, Owner’s predecessor-in-interest and Xxxxxxxx have entered into that certain Generator Development and License Agreement dated as of April 13, 2001, as amended, a copy of which is attached hereto as Exhibit B and incorporated herein by reference (the “Generator Agreement”), and that certain Supplemental HVAC System Operating and License Agreement dated as July 31, 2002, a copy of which is attached hereto as Exhibit C and incorporated herein by reference (the “HVAC Agreement”).

D. Archipelago is a significant user of the data processing and related facilities located in the Data Rooms pursuant to a separate agreement between Archipelago and Xxxxxxxx.

E. Recognizing that Archipelago’s continued ability to use the data processing and related facilities located in the Data Rooms is of critical importance to the ability of Archipelago to conduct its business in the Archipelago Premises, Owner and the Archipelago desire to establish certain rights, safeguards, obligations and priorities with regard to their respective interests in the Xxxxxxxx Lease with respect to the Data Rooms, the Generator Agreement and the HVAC Agreement.

NOW THEREFORE, in consideration of the mutual covenants of the parties set forth herein and other good and valuable consideration, Archipelago and Owner agree as follows:

1. Subject to the provisions of Section 4 hereof, as used herein, the term “Xxxxxxxx Lease” shall include the Xxxxxxxx Lease (as defined in Recital B above) and (i) all amendments thereto

entered into subsequent to the date of this Agreement and (ii) any and all renewal or extension options thereunder exercised subsequent to the date of this Agreement.

2. Provided the Archipelago Lease is in full force and effect and no default by Archipelago then exists thereunder, Owner and Archipelago agree that:

(a) if the Xxxxxxxx Lease shall terminate, expire or otherwise be terminated, rejected or disaffirmed (including rejection or disaffirmation by Xxxxxxxx pursuant to any bankruptcy, insolvency or other law affecting creditors’ rights) or Owner shall elect to exercise its right to re-enter the Xxxxxxxx Premises without terminating the Xxxxxxxx Lease, then notwithstanding such termination, expiration, disaffirmation or re-entry, the Xxxxxxxx Lease with respect to the Data Rooms shall continue as a direct lease between Owner, as Landlord, and Archipelago, as Tenant, upon all of the terms, covenants, conditions and agreements set forth in the Xxxxxxxx Lease as are applicable to the Data Rooms, for the period up to and including the earlier to occur of (i) the expiration or earlier termination of the term of the Archipelago Lease or Archipelago’s right to possession of the Archipelago Premises, and Archipelago covenants and agrees to assume all of the obligations and liabilities Tenant thereafter arising under the Xxxxxxxx Lease as are applicable to the Data Rooms and to attorn to Owner thereunder. Archipelago acknowledges that the 20th Floor Data Room is part of the entire 20^th floor of the Building that is presently being leased by Xxxxxxxx under the Xxxxxxxx Lease and that if Archipelago assumes the Xxxxxxxx Lease with respect to the Data Rooms as provided herein, it will be necessary for Owner to separately demise the 20^th Floor Data Room from the remainder of the 20^th floor of the Building and to a create a Building standard multi-tenant corridor and elevator lobby on such floor. Accordingly, Archipelago agrees that in such event, it shall, within thirty (30) days after written demand, reimburse Owner, as additional rent under the Xxxxxxxx Lease as assumed by Archipelago, for all design, engineering, permitting and construction costs incurred by Owner to construct a Building standard multi-tenant corridor and elevator lobby on the 20^th floor of the Building and to separately demise the 20^th Floor Data Room and provide direct access thereto from such corridor (including, without limitation, separation of any utilities serving such corridor and elevator lobby and the 20^th Floor Data Room and causing such corridor and elevator lobby and the 20^th Floor Data Room to comply all then applicable laws, codes, regulations and ordinances). In addition, upon completion of the demising of the 20^th Floor Data Room, Owner shall remeasure the rentable area thereof using the then current space measurement standard for the Building, which remeasurement shall be deemed to be the rentable area of the 20^th Floor Data Room for all purposes under the Xxxxxxxx Lease as assumed by Archipelago hereunder (or if applicable, the amendment to the Archipelago Lease adding the Data Rooms to the Archipelago Premises), including, without limitation, for the determination of rent and other charges payable by Archipelago thereunder with respect to the 20^th Floor Data Room. For the purposes of this Section 2(a), a renewal or extension of the term of the Xxxxxxxx Lease as to all or any portion or portions of the Xxxxxxxx Premises shall not be deemed to be an expiration or termination thereof.

(b) if the Generator Agreement shall terminate, expire or otherwise be terminated, rejected or disaffirmed (including rejection or disaffirmation by Xxxxxxxx pursuant to any bankruptcy, insolvency or other law affecting creditors’ rights), then notwithstanding such termination, expiration, rejection or disaffirmation, the

Generator Agreement shall continue as a direct agreement between Owner and Archipelago, as Licensee, upon all of the terms, covenants, conditions and agreements set forth therein, for the period up to and including the expiration or earlier termination of the term of the Archipelago Lease or Archipelago’s right to possession of the Archipelago Premises, mid Archipelago covenants and agrees to assume all of the obligations and liabilities of Licensee thereafter arising under the Generator Agreement and to attorn to Owner thereunder.

(c) if the HVAC Agreement shall terminate, expire or otherwise be terminated, rejected or disaffirmed (including rejection or disaffirmation by Xxxxxxxx pursuant to any bankruptcy, insolvency or other law affecting creditors’ rights), then notwithstanding such termination, expiration, rejection or disaffirmation, the HVAC Agreement shall continue as a direct agreement between Owner and Archipelago, as Licensee, upon all of the terms, covenants, conditions and agreements set forth therein, for the period up to and including the expiration or earlier termination of the term of the Archipelago Lease or Archipelago’s right to possession of the Archipelago Premises, and Archipelago covenants and agrees to assume all of the obligations and liabilities of Licensee thereafter arising under the HVAC Agreement and to attorn to Owner thereunder.

3. In the event of an assumption and attornment by Archipelago of any or all of (i) the Xxxxxxxx Lease with respect to the Data Rooms, (ii) the Generator Agreement and/or (iii) the HVAC Agreement as provided in Section 2 above, Archipelago shall be obligated to promptly cure all non-monetary defaults under each such assumed agreement(s) existing on the respective date(s) of such assumption and attornment, provided that Archipelago shall not be obligated to cure (i) any monetary defaults under such assumed agreement(s) existing on the respective date(s) of such assumption and attornment nor (ii) any defaults (monetary or non-monetary) under the Xxxxxxxx Lease with respect to any portion of the Xxxxxxxx Premises other than the Data Rooms.

4. In consideration of Archipelago’s covenant to assume and attorn to Owner as set forth above, Owner covenants that during the Term of the Archipelago Lease, Owner shall not, without the prior written consent of Archipelago, modify or amend (a) the Xxxxxxxx Lease with respect to the Data Rooms, (b) the Generator Agreement or (c) the HVAC Agreement, the effect of which modification or amendment would be to increase the rent or other charges payable thereunder, shorten the term thereof, or materially increase the obligations or reduce or impair the rights of Archipelago thereunder, in the event Archipelago assumes such agreement(s) and attorns to Owner thereunder pursuant to this Agreement.

5. At any time after the date Archipelago assumes the Xxxxxxxx Lease with respect to the 20^th Floor Data Room and attorns to Owner thereunder as provided herein (or the date the Archipelago Lease is amended to add the 20^th Floor Data Room to the Archipelago Premises thereunder as provided in Section 8 below), Owner shall have the right to substitute for the 20^th Floor Data Room other premises within the Building (the “New Data Room”), provided that the New Data Room shall be of comparable size and shall either have substantially the same configuration (including all associated infrastructure, such as data and telecom cabling and connectivity, utilities, back-up power and supplemental HVAC, meeting or exceeding the technical specifications set forth on Exhibit E attached hereto (collectively, “Associated Infrastructure”)) as the 20^th Floor Data Room or a configuration (including Associated Infrastructure) substantially as usable for the purposes for which 20^th Floor Data Room are being used by Archipelago. Archipelago shall vacate

and surrender the 20th Floor Data Room on or before the later of (A) the sixtieth (60th) day after the date Owner gives notice of substitution or (B) the day after (1) Owner has substantially completed the work to be done by Owner in the New Data Room pursuant to this Section 5 and (ii) Archipelago has confirmed, to its reasonable satisfaction, that the property, fixtures, cabling and equipment installed or reinstalled in the New Data Room and Associated Infrastructure are functioning at a level meeting or exceeding the technical specifications set forth on Exhibit E attached hereto (and as to which Archipelago agrees to conduct all necessary testing and optimization thereof as expeditiously as is reasonably practicable). As of the earlier of the date of such vacation and surrender or the date when such vacation and surrender is required, the New Data Room shall be deemed part of the Premises under the Xxxxxxxx Lease as assumed by Archipelago hereunder (or the Archipelago Premises in the event the Archipelago Lease is amended to add the 20^th Floor Data Room to the Archipelago Premises thereunder as provided in Section 8 below) and the 20th Floor Data Room shall cease to be part of Premises under the Xxxxxxxx Lease as assumed by Archipelago hereunder (or the Archipelago Premises in the event the Archipelago Lease is amended to add the 20^th Floor Data Room to the Archipelago Premises thereunder as provided in Section 8 below). Owner shall (i) prior to commencing the work to be done by Owner in the New Data Room pursuant to this Section 5, provide Archipelago with a reasonably detailed budget showing Owner’s good faith estimate of all out-of-pocket expenses to be incurred in connection with moving, installing and/or reinstalling Archipelago’s property, fixtures, cabling and equipment from the 20th Floor Data Room to the New Data Room, and to improve the New Data Room so that they are substantially similar to the 20^th Floor Data Room (including Associated Infrastructure), (ii) pay for the actual and reasonable out-of-pocket expenses incurred in connection with moving, installing and/or reinstalling its property, fixtures, cabling and equipment from the 20^th Floor Data Room to the New Data Room (unless Archipelago elects to pay all or a portion of such costs directly, in which case Owner shall promptly reimburse Archipelago for such costs paid by Archipelago upon presentation of paid invoices therefore to Owner), and (iii) improve the New Data Room, at Owner’s sole cost and expense, so that they are substantially similar to the 20^th Floor Data Room (including Associated Infrastructure). However, instead of paying Archipelago’s expenses incurred in connection with moving, installing and/or reinstalling its property, fixtures, cabling and equipment, Owner may elect to either move, install and/or reinstall Archipelago’s property, fixtures, cabling and equipment or provide personnel to do so under Archipelago’s direction, in which event such move, installation and/or reinstallation may not be made except during evenings, weekends or holidays, so as to incur the least inconvenience to Archipelago. Archipelago shall not be entitled to any compensation for any inconvenience or interference with Archipelago’s business, nor to any abatement or reduction in rent or other charges payable by Archipelago under the Xxxxxxxx Lease as assumed by Archipelago hereunder or under the Archipelago Lease, nor shall .-archipelago’s obligations under the Xxxxxxxx Lease as assumed by Archipelago hereunder or the Archipelago Lease be otherwise affected, as a result of the substitution of the New Data Room, except as otherwise expressly provided in this Section 5. Archipelago agrees to cooperate with Owner so as to facilitate the prompt completion by Owner of its obligations hereunder. Without limiting the generality of the preceding sentence, Archipelago agrees to promptly provide to Owner such approvals, instructions, plans, specifications and other information as may be reasonably requested by Owner in connection with such obligations. Upon substitution of the New Data Room for the 20th Floor Data Room, the rentable area of the New Data Room shall be substituted for the rentable area of the 20th Floor Data Room for all purposes under the Xxxxxxxx Lease as assumed by Archipelago hereunder (or under the Archipelago Lease in the event the Archipelago Lease is amended

to add the 20^th Floor Data Room to the Archipelago Premises thereunder as provided in Section 8 below), including, without limitation, recalculating and adjusting the base rent and Archipelago’s proportionate share based on the rentable area of the New Data Room (provided that in no event shall the base rent and/or proportionate share with respect to the New Data Room be increased over the corresponding amounts that would have been in effect for the 20^th Floor Data Room had the substitution not occurred). At Owner’s request, Archipelago shall execute a supplement to the Xxxxxxxx Lease as assumed by Archipelago hereunder (or to the Archipelago Lease in the event the Archipelago Lease is amended to add the 20^th Floor Data Room to the Archipelago Premises thereunder as provided in Section 8 below), confirming the substitution of the New Data Room for the 20^th Floor Data Room. Any failure of Archipelago to surrender possession of the 20th Floor Data Room as and when required by this Section 5 shall be deemed a holding over by Archipelago pursuant to the Xxxxxxxx Lease as assumed by Archipelago hereunder (or to the Archipelago Lease in the event the Archipelago Lease is amended to add the 20^thFloor Data Room to the Archipelago Premises thereunder as provided in Section 8 below).

6. Owner shall, from and after the date hereof, so long as the Archipelago Lease is in full force and effect and no Default by Archipelago then exists thereunder, give to Archipelago, in the manner provided herein for the giving of notice, copies of all formal notices of default and demands to cure, termination notices, and change of address notices that Owner may give to Xxxxxxxx pursuant to the Xxxxxxxx Lease, the Generator Agreement or the HVAC Agreement. Owner acknowledges and agrees that Archipelago shall have the right (but not the obligation), at Archipelago’s option, to cure any default by Xxxxxxxx under said agreement(s), within the same grace or cure periods as are available to Xxxxxxxx thereunder. Owner agrees to accept performance by Archipelago of any of Xxxxxxxx’x monetary or non-monetary obligations under the said agreement(s), as if same were performed by Xxxxxxxx.

7. Notices given pursuant to the terms of this Agreement shall be given in the same mariner as provided in the Archipelago Lease.

8. The above provisions shall be self-operative and effective without execution of any further instruments on the part of either party hereto. However, Archipelago agrees to execute and deliver to Owner such other instruments, in a form reasonably acceptable to Archipelago, as shall be reasonably requested by Owner in order to comply with these provisions, including, without limitation in the event Archipelago assumes the obligations of Xxxxxxxx under the Xxxxxxxx Lease with respect to the Data Rooms as provided herein, an amendment to the Xxxxxxxx Lease excluding therefrom all portions of the Xxxxxxxx Premises other than the data Rooms, effective as of the date of such assumption, provided that at the request of either Owner or Archipelago, Owner and Archipelago agree to enter into an amendment to the Archipelago Lease adding the Data Rooms to the Archipelago Premises upon the same rent and other economic terms applicable thereto under the Xxxxxxxx Lease, effective as of the date Archipelago would have assumed the Xxxxxxxx Lease with respect thereto, whereupon the Xxxxxxxx Lease shall be deemed terminated and of no further force and effect.

9. This Agreement may not be modified other than by an agreement in writing signed by the parties hereto or by their respective successors in interest.

10. This Agreement shall run with the land and inure to the benefit of and be binding upon the parties and their successors and assigns.

IN WITNESS WHEREOF, the parties hereto or their authorized representatives or officers have signed this document as of the date first above written.

LEASE

By this Lease Landlord Leases to Tenant and Tenant Leases from Landlord the Premises in the Building as set forth and described on the Reference Page. The Reference Page, including all terms defined thereon, is incorporated as part of this Lease.

1. USE AND RESTRICTIONS ON USE. The Premises are to be used solely for the purposes stated on the Reference Page. Tenant shall not do or permit anything to be done in or about the Premises which will in any way obstruct or interfere with the rights of other Tenant’s or occupants of the Building or injure, annoy, or disturb them or allow the Premises to be used for any improper, immoral, unlawful, or objectionable purpose. Tenant shall not do, permit or suffer in, on, or about the Premises the sale of any alcoholic liquor as defined in the Illinois Liquor Control Act without the written consent of Landlord first obtained, or the commission of any waste. Tenant shall comply with all governmental laws, ordinances and regulations applicable to the use of the Premises and its occupancy and shall promptly comply with all governmental orders and directions for the correction, prevention and abatement of any violations in or upon, or in connection with, the Premises, all at Tenant’s sole expense. Tenant shall not do or permit anything to be done on or about the Premises or bring or keep anything into the Premises which will in any way increase the rate of, invalidate or prevent the procuring of any insurance protecting against loss or damage to the Building or any of its contents by fire or other casualty or against liability for damage to property or injury to persons in or about the Building or any part thereof.

2. TERM.

2.1. The Term (if and as required by the context, “Initial Term”) of this Lease shall begin on the date (“Commencement Date”) which shall be the later of the Scheduled Commencement Date as shown on the Reference Page and the date that Landlord shall tender possession of the Premises to Tenant. Landlord shall tender possession of the Premises with all the work, if any, to be performed by Landlord pursuant to Exhibit B to this Lease substantially completed. Tenant shall deliver a punch list of items not completed within 30 days after Landlord tenders possession of the Premises and Landlord agrees to proceed with due diligence to perform its obligations regarding such items. Upon any extension of the Commencement Date, the Termination Date shall be extended to the same extent so that the Term of this Lease shall continue for the length of tine indicated on the Reference Page unless sooner terminated as provided in this Lease. Landlord and Tenant shall execute a memorandum setting forth the actual Commencement Date and Termination Date.

2.2. Tenant agrees that in the event of the inability of Landlord to deliver possession of the Premises on the Scheduled Commencement Date, Landlord shall not be liable for any damage resulting from such inability, but Tenant shall not be liable for any rent until the time when Landlord can, after notice to Tenant, deliver possession of the Premises to Tenant. No such failure to give possession on the Scheduled Commencement Date shall affect the other obligations of Tenant under this Lease, except that if Landlord is unable to deliver possession of

the Premises within one hundred twenty (120) days of the Scheduled Commencement Date (other than as a result of strikes, shortages of materials or similar matters beyond the reasonable control of Landlord and Tenant is notified by Landlord in writing as to such delay), Tenant shall have the option to terminate this Lease unless said delay is as a result of: (a) Tenant’s failure to agree to plans and specifications; (b) Tenant’s request for materials, finishes or installations other than Landlord’s standard except as for such, if any, that Landlord shall have expressly agreed to furnish without extension of time agreed by Landlord; (c) Tenant’s change in any plans or specifications; or, (d) performance or completion by a party employed by Tenant. If said delay is the result of any of the foregoing, the Commencement Date and the payment of rent under this Lease shall be accelerated by the number of days of such delay.

2.3. In the event Landlord shall permit Tenant to occupy the Premises prior to the Commencement Date, such occupancy shall be subject to all the provisions of this Lease. Said early possession shall not advance the Termination Date.

2. RENT

3.1. The rate of Annual Rent and the Monthly Installments thereof to be in effect throughout the Term of this Lease shall be as follows:

Period		Annual Rent		Monthly Installment
[***]		[***]		[***]

* For more than a 1 year period

3.2. Tenant agrees to pay to Landlord the Annual Rent in effect from time to time by paying the Monthly Installment of Rent then in effect on or before the first day of each full calendar month during the Term, except that the first month’s rent shall be paid upon the execution of this Lease. The Monthly Installment of Rent in effect at any time shall be one-twelfth of the Annual Rent in effect at such time. Rent for any period during the Term which is less than one (1) full month shall be a prorated portion of the Monthly Installment of Rent based upon a thirty (30) day month. Said rent shall be paid to Landlord, without deduction or offset and without notice or demand, at the Landlord’s address, as set forth on the Reference page, or to such other person or at such other place as Landlord may from time to time designate in writing.

3.3. Tenant recognizes that late payment of any rent or other sum due under this Lease will result in administrative expense to Landlord, the extent of which additional expense is extremely difficult and economically impractical to ascertain. Tenant therefore agrees that if rent or any other sum is not paid when due and payable pursuant to this Lease, such amount shall bear interest at twelve percent (12%) per annum for the first ten (10) days after due and when such amount remains due and unpaid for more than ten (10) days after said amount is due, such interest shall be supplanted by a late charge in an amount equal to the greater of: (a) Fifty Dollars ($50.00), or (b) a sum equal to five percent (5%) per month of the unpaid rent or other payment. The amount of the late charge to be paid by Tenant shall be reassessed and added to Tenant’s obligation for each successive monthly period until paid. The provisions of this

Section 3.3 in no way relieve Tenant of the obligation to pay rent or other payments on or before the date on which they are due, nor do the terms of this Section 3.3 in any way affect Landlord’s remedies pursuant to Article 20 of this Lease in the event said rent or other payment is unpaid after date due.

3.4. No security or guarantee which may now or hereafter be furnished to Landlord for the payment of rent or the performance of Tenant’s other obligations under this Lease shall in any way constitute a bar to the recovery of the Premises or defense to any action in unlawful detainer or to any other action which Landlord may bring for a breach of any of the terms, covenants or conditions of this Lease.

4. RENT ADJUSTMENTS

4.1. For the purpose of this Article 4, the following terms are defined as follows:

4.1.1. Lease Year: Each calendar year falling partly or wholly within the Term.

4.1.2. Direct Expenses: All direct costs of operation, maintenance, repair and management of the Building (including the reasonable amount of any credits which Landlord may grant to particular tenants of the Building in lieu of providing any standard services or paying any standard costs described in this Section 4.1.2 for similar tenants), as determined in accordance with generally accepted accounting principles, including the following costs by way of illustration, but not limitation: water and sewer charges; insurance premiums of or relating to all insurance policies and endorsements deemed by Landlord to be reasonably necessary or desirable and relating in any manner to the protection, preservation, or operation of the Building or any part thereof and if Landlord self insures or carries deductibles in excess of $2,000.00, amounts equal to the savings in premiums effected thereby as reasonably determined by Landlord; utility costs, including, but not limited to, the cost of heat, light, power, steam, gas, and waste disposal; the cost of janitorial services; the cost of security and alarm services; window cleaning costs; labor costs; costs and expenses of managing the Building including management fees; air conditioning costs; elevator maintenance fees and supplies; material costs; equipment costs including the cost of maintenance, repair and service agreements and rental and leasing costs; purchase costs of equipment other than capital items; current rental and leasing costs of items which would be amortizable capital items if purchased; tool costs; licenses, permits and inspection fees; wages and salaries; employee benefits and payroll taxes; accounting and legal fees; any sales, use or service taxes incurred in connection therewith.

4.1.3. Direct Expenses shall not include depreciation or amortization of the Building or equipment in the Building except as provided in Section 4.7 of this Lease, loan principal payments, costs of alterations of tenants’ premises, leasing commissions, interest expenses on long-term borrowings, advertising costs or management salaries for executive personnel other than personnel located at the Building.

4.1.4. Taxes: Real estate taxes and any other taxes, charges and assessments which are levied with respect to the Building or the land

appurtenant to the Building, or with respect to any improvements, fixtures and equipment or other property of Landlord, real or personal, located in the Building and used in connection with the operation of the Building and said land, and/or any tax which shall be levied in addition to or in lieu of real estate, possessory interest or personal property taxes, any payments to any ground lessor in reimbursement of tax payments made by such lessor; and all fees, expenses and costs incurred by Landlord in investigating, protesting, contesting or in any way seeking to reduce or avoid increase in any assessments, levies or the tax rate pertaining to any Taxes to be paid by Landlord in any Lease Year. Taxes shall not include any corporate franchise, or estate, inheritance or net income tax, or tax imposed upon any transfer by Landlord of its interest in this Lease or the Building.

4.2. Tenant shall pay as additional rent for each Lease Year Tenant’s Proportionate Share of Direct Expenses incurred and Taxes paid for said Lease Year. The annual determination of Direct Expenses shall be made by Landlord and if certified by a nationally recognized firm of public accountants selected by Landlord shall be binding upon Landlord and Tenant. Tenant may review the books and records supporting such determination in the office of Landlord, or Landlord’s agent, during normal business hours, upon giving Landlord five (5) days advance written notice within sixty (60) days after receipt of such determination, but in no event more often than once in any one year period. In the event that during all or any portion of any Lease Year the Building is not fully rented and occupied Landlord may make any appropriate adjustment in occupancy-related Direct Expenses for such Lease Year for the purpose of avoiding distortion of the amount of such Direct Expenses to be attributed to Tenant by reason of variation in total occupancy of the Building, by employing sound accounting and management principles to determine Direct Expenses that would have been paid or incurred by Landlord had the Building been fully rented and occupied, and the amount so determined shall be deemed to have been Direct Expenses for such Lease Year.

4.3. Prior to the actual determination thereof Landlord may from time to time estimate the amount of Tenant’s Proportionate Share of Direct Expenses or Taxes for any Lease Year or portion thereof, at Landlord’s option including amounts estimated to became due from Tenant on account of Taxes pursuant to Articles 6 and/or 29 of this Lease, and Tenant shall pay the amount to become due from Tenant, as so estimated, as additional rent in equal monthly installments added to and becoming a part of the Monthly Installments of Rent due from Tenant under this Lease in such Lease Year or portion thereof, at such rate that the full estimated amount of Tenant’s Proportionate Share of each payment of Direct Expenses or Taxes to be made by Landlord shall have been paid to Landlord when or before said payment by Landlord is due. Initially, the monthly amount of such additional rent to be paid by Tenant shall be as set forth on the Reference Page of this Lease, but by written notice to Tenant Landlord may change the amount of such additional rent to be paid by Tenant at any time upon not less than twenty (20)

days notice, and each such revised rate of monthly installments of additional rent shall remain in effect until revised by further written notice to Tenant pursuant to this Lease.

4.4. When the above mentioned actual determination of Direct Expenses is made or the actual xxxx or bills for the Taxes to be paid by Landlord in any Lease Year is issued and Tenant is so notified in writing, then:

4.4.1. If the total additional rent Tenant actually paid pursuant to Section 4.3 of this Lease for the Lease Year is less than Tenant’ s Proportionate Share of the actual Direct Expenses or Taxes, then Tenant shall pay to Landlord as additional rent in one lump sum within thirty (30) days of receipt of Landlord’s xxxx therefor the difference between such total additional rent actually paid by Tenant pursuant to said Section 4.3 of this Lease for the Lease Year and the Tenant’s Proportionate Share of said Direct Expenses or Taxes; or

4.4.2. If the total additional rent Tenant actually paid pursuant to Section 4.3 of this Lease for the Lease Year is more than Tenant’s Proportionate Share of the actual Direct Expenses or Taxes as so determine, then Landlord shall credit the difference against the then next due payments to be made by Tenant under this Article 4.

4.5. If the Commencement Date is other than January 1 or if the Termination Date is other than December 31, Tenant’s Proportionate Share of Direct Expenses and Taxes for the Lease Year in which said Date occurs shall be prorated based upon a three hundred sixty-five (365) day year.

4.6. Even though the Term has expired and Tenant has vacated the Premises, when the final determination is made of Tenant’s Proportionate Share of Direct Expenses or Taxes for the Lease Year in which the Lease terminated, Tenant shall pay any increase due over the estimated Direct Expenses or Taxes paid; and conversely any overpayment, less any amounts due Landlord under this Lease, shall be rebated to Tenant.

4.7. In addition Landlord shall be entitled to amortize and include as an additional rental adjustment: (i) an allocable portion of the cost of capital improvement items which are reasonable calculated to reduce operating expenses; (ii) fire sprinklers and suppression systems and other life safety systems; and (iii) other capital expenses which are required under any governmental laws, regulations or ordinances which were not applicable to the Building at the time it was constructed. All such costs shall be amortized over the reasonable life of such improvements in accordance with such reasonable life and amortization schedules as shall be determined by Landlord in accordance with generally accepted accounting principles, with interest on the unamortized amount at one percent (1%) in excess of the prime lending rate announced as such by The Northern Trust Company as of February 1^st of each year.

5. SECURITY DEPOSIT. Tenant shall deposit the Security Deposit with Landlord upon or before the execution of this Lease. Said sum shall be held by Landlord as security for the faithful performance by Tenant of all the terms, covenants and conditions of this Lease to be kept and performed by Tenant and not as an advance rental deposit or as a measure of Landlord’s damage in case of Tenant’s default. If Tenant defaults with respect to any provision of this

Lease, Landlord may use any part of the Security Deposit for the payment of any rent or any other sum in default, or for the payment of any amount which Landlord may spend or become obligated to spend by reason of Tenant’s default, or to compensate Landlord for any other loss or damage which Landlord may suffer by reason of Tenant’s default. If any portion is so used, Tenant shall within five (5) days after written demand therefor, deposit with Landlord an amount sufficient to restore the Security Deposit to its original amount and Tenant’s failure to do so shall be a material breach of this Lease. Except to such extent, if any, as shall be required by law, Landlord shall not be required to keep the Security Deposit separate from its general funds, and Tenant shall no be entitled to interest on such deposit. If Tenant shall fully and faithfully perform every provision of this Lease to be performed by it, the Security Deposit or any balance thereof shall be returned to Tenant at such time after termination of this Lease when Landlord shall have determined that all of Tenant’s obligations under this Lease have been fulfilled.

10.7. Tenant will pay to Landlord an demand a sum equal to all of Landlord’s reasonable costs, including attorney’s fees, incurred in investigating and considering any proposed or purported assignment or pledge of this Lease or sublease of any of the Premises, regardless of whether Landlord shall consent to, refuse consent, or determine that Landlord’s consent is not required for, such assignment, pledge or sublease. Any purported sale, assignment, mortgage, transfer of this Lease or subletting which does not comply with the provisions of this Article 10 shall be void.

20. REMEDIES.

20.1. Except as otherwise provided in Article 21 of this Lease, upon the occurrence of any of the Events of Default described or referred to in Article 19 of this Lease, Landlord shall have the option to pursue any one or more of the following remedies without any notice or demand whatsoever, concurrently or consecutively and not alternatively:

20.1.1. Landlord may, at its election, terminate this Lease or terminate Tenant’s right to possession only, without terminating the Lease.

20.1.2. Upon any termination of this Lease, whether by lapse of time or otherwise, or upon any termination of Tenant’s right to possession without termination of the Lease, Tenant shall surrender possession and vacate the Premises immediately, and deliver possession thereof to Landlord, and Tenant hereby grants to Landlord full and free license to enter into and upon the Premises in such event with or without process of law and to repossess Landlord of the Premises as of Landlord’s former estate and to expel or remove Tenant and any others who may be occupying or be within the Premises and to remove Tenant’s signs and other evidence of tenancy and all other property of Tenant therefrom without being deemed in any manner guilty of trespass, eviction or forcible entry or detainer, and without incurring any liability for any damage resulting therefrom, Tenant waiving any right to claim damages for such reentry and expulsion, and without relinquishing Landlord’s right to rent or any other right given to Landlord under this Lease or by operation of law.

20.1.3. Upon any termination of this Lease, whether by lapse of time or otherwise, Landlord shall be entitled to recover as damages, all rent, including any amounts treated as additional rent under this Lease, and other sums due and payable by Tenant on the date of termination, plus as liquidated damages and not as a penalty, an amount equal to either, as Landlord shall elect: (i) the total amount of Annual Rent and additional rent which was due to be paid under this Lease for the then most recent Lease Year or such shorter time as equals the then otherwise unexpired term of this Lease; or (ii) the sum: (a) an amount equal to the then present value of the rent reserved in this Lease for the residue of the stated Term of this Lease including any amounts treated as additional rent under this Lease and all other sums provided in this Lease to be paid by Tenant, minus the fair rental value of the Premises for such residue (which the parties agree shall not exceed eighty percent (80%) of the then present value of the rent reserved for such residue); (b) the value of the time and expense necessary to obtain a replacement tenant or tenants, and the estimated expenses described in Section 20.1.4 of this Lease relating to recovery of the Premises, preparation for reletting and for reletting itself; and (c) the cost of performing any other covenants which would have otherwise been performed by Tenant.

20.1.4. Upon any termination of Tenant’s right to possession only without termination of the Lease:

20.1.4.1. Neither such termination of Tenant’s right to possession nor Landlord’s taking and holding possession thereof as provided in Section 20.1.2 of this Lease shall terminate the Lease or release Tenant, in whole or in part, from any obligation, including Tenant’s obligation to pay the rent, including any amounts treated as additional rent, under this Lease for the full Term.

20.1.4.2. Landlord may, but need not, relet the Premises or any part thereof for such rent and upon such terms as Landlord, in its sole discretion, shall determine (including the right to relet the Premises for a greater or lesser term than that remaining under this Lease, the right to relet the Premises as a part of a larger area, and the right to change the character or use made of the Premises). In connection with or in preparation for any reletting, Landlord may, but shall not be required to, make repairs, alterations and additions in or to the Premises and redecorate the same to the extent Landlord deems necessary or desirable, and Tenant shall, upon demand, pay the cost thereof, together with Landlord’s expenses of reletting, including, without limitation, any broker’s commission incurred by Landlord. If Landlord decides to relet the Premises or a duty to relet is imposed upon Landlord by law, Landlord and Tenant agrees that nevertheless Landlord shall at most be required to use only the same efforts Landlord then uses to lease premises in the Building generally and that in any case that Landlord shall not be required to give any preference or priority to the showing or leasing of the Premises over any other space that Landlord may be leasing or have available and may place a suitable prospective tenant in any such other space regardless of when such other space becomes available. Landlord shall not be required to observe any instruction given by Tenant about any reletting or accept any tenant offered by Tenant unless such offered tenant has a credit-worthiness acceptable to Landlord and Leases the entire Premises upon terms and conditions including a rate of rent (after giving effect to all expenditures by Landlord for Tenant improvements, brokers commissions and other leasing costs) all no less favorable to Landlord than as called for in this Lease, nor shall Landlord be required to make or permit any assignment or sublease for more than the current term or which Landlord would not be required to permit under the provisions of Article 10 of this Lease.

20.1.4.3. Until such time as Landlord shall elect to terminate the Lease and shall thereupon be entitled to recover the amounts specified in such case in Section 20.1.3 of this Lease, Tenant shall pay to Landlord upon demand the full amount of all rent, including any amounts treated as additional rent under this Lease and other sums reserved in this Lease for the remaining Term, together with the costs of repairs, alterations, additions, redecorating and Landlord’s expenses of reletting and the collection of the rent accruing therefrom (including attorney’s fees and broker’s commissions), as the same shall then be due or become due from time to time, less only such consideration as Landlord may have received from any reletting of the Premises; and Tenant agrees that Landlord may file suits from time to time to recover any sums falling due under this Article 20 as they become due. Any proceeds of reletting by Landlord in excess of the amount then owed by Tenant to Landlord from time to time shall be credited against Tenant’s future obligations under this Lease but shall not otherwise be refunded to Tenant or inure to Tenant’s benefit.

20.2. If, on account of any breach or default by Tenant in Tenant’s obligations under the terms and conditions of this Lease, it shall become necessary or appropriate for Landlord to

employ or consult with an attorney concerning or to enforce or defend any of Landlord’s rights or remedies arising under this Lease, Tenant agrees to pay all Landlord’s reasonable attorney’s fees so incurred. Tenant expressly waives any right to: (a) trial by jury; and (b) service of any notice required by any present or future law or ordinance applicable to landlords or tenants but not required by the terms of this Lease.

20.3. Pursuit of any of the forgoing the remedies shall not preclude pursuit of any of the other remedies provided in this Lease or any other remedies provided by law (all such remedies being cumulative), nor shall pursuit of any remedy provided in this least constitute off forfeiture or waiver of any rent due to Landlord under this Lease or of any damages accruing to Landlord by reason of the violation of any other terms, provisions and covenants contained in this Lease.

20.4. No act or thing done by Landlord or its agents during the term shall be deemed a termination of this Lease or an acceptance of the surrender of the Premises, and no agreement to terminate this Lease or accept or surrender of said Premises shall be valid, unless in writing signed by the Landlord. No waiver by Landlord of any violation or breach of any of the terms, provisions and covenants contained in this Lease shall be deemed or construed to constitute a waiver of any other violation or breach of any of the terms, provisions and covenants contained in this Lease. Landlords acceptance of the payment of rental or other payments after the occurrence of an event of default shall not be construed as a waiver of such default, unless Landlord so notifies Tenant in writing. Forbearance by Landlord in enforcing one or more of the remedies provided in this Lease upon an event of default shall not been deemed or construed to constitute a waiver of such default or of Landlords write to enforce any such remedies with respect to such default or any subsequent default.

21. TENANT’S BANKRUPTCY OR INSOLVENCY.

21.1. If at any time in for so long as Tenant shall be subjected to the provisions of the United States bankruptcy code or other law of the United States or any state thereof for the protection of debtors as in effect at such time (each a “debtor’s law”):

21.1.1. To the extent that the provisions of such Debtor’s Law shall prohibit the declaring of an event described in Article 19 of this Lease to be a default under the this Lease, worthy enforcement of any right or remedy provided to Landlord in said Article 20, such event shall not be a default and such right or remedy shall not be enforced.

21.1.2. Except to the extent expressly provided by such Debtor’s Law, Tenant, Tenant as debtor-in-possession, in any trustee or receiver of Tenant’s assets (each a “Tenant’s Representative”) shall have no greater right to remain in possession of all or any part of the Premises than would be accorded to Tenant if such Debtor’s Law were not applicable; if such Debtor’s Law requires or permits the imposition upon or payment by Tenant’s Representative of charges for the use or possession thereof, such charges shall in no event be less than the rent an additional rent which are or would be payable absence of such Debtor’s Law pursuant to Articles three and four of this Lease with respect to such portion of the Premises for the period of such possession or use thereof by Tenant’s Representative.

21.1.3. Tenant’s representative shall have no greater of right to assume or assign this Lease or any interest in this Lease, or to sublease any of the Premises then accorded to Tenant in Article 10 of this Lease, except to the extent Landlord shall be required to permit such assumption, assignment or sublease by the provisions of such debtors long. Without limitation of the generality of the foregoing, any right of any Tenant’s representative to assume or assign this Lease or to sublease any of the Premises shall be subject to the conditions that:

21.1.3.1. Such Debtor’s Law shall provide to Tenant’s Representative a right of assumption of this Lease which Tenant’s Representative shall have timely exercised and Tenant’s Representative shall have fully cured any default of Tenant under this Lease.

21.1.3.2. Tenant’s Representative or the proposed assignee, as the case shall be, shall have deposited with Landlord as security for the timely payment of Rent an amount equal to the larger of: (a) three months’ Rent and other monetary charges accruing under this Lease; and (b) any sum specified in Article 5; and shall have provided Landlord with adequate other assurance of the future performance of the obligations of the Tenant under this Lease. Without limitation, such assurances shall include, at least, in the case of assumption of this Lease, demonstration to the satisfaction of the Landlord that Tenant’s Representative has and will continue to have sufficient unencumbered assets after the payment of all secured obligations and administrative expenses to assure Landlord that Tenant’s Representative will have sufficient funds to fulfill the obligations of Tenant under this Lease; and, in the case of assignment, submission of current financial statements of the proposed assignee, audited by an independent certified public accountant reasonably acceptable to Landlord and showing a net worth and working capital in amounts determined by Landlord to be sufficient to assure that the future performance by such assignee of all of the Tenant’s obligations under this Lease.

21.1.3.3. The assumption or any contemplated assignment of this Lease or subleasing any part of the Premises, as shall be the case, will not breach any provision in any other lease, mortgage, financing agreement or other agreement by which Landlord is bound.

21.1.3.4. Landlord shall have, or would have had absent the Debtor’s Law, no right under Article 10 of this Lease to refuse consent to the proposed assignment or sublessee by reason of the identity or nature of the proposed assignee or sublease or the proposed use of the Premises concerned.

22. QUIET ENJOYMENT. Landlord represents and warrants that it has full right and authority to enter into this Lease and that Tenant, while paying the rental and performing its other covenants and agreements contained in this Lease, shall peaceably and quietly have, hold and enjoy the Premises for the Term without hindrance or molestation from Landlord subject to the terms and provisions of this Lease. Landlord shall not be liable for any interference or disturbance by other tenants or third persons, nor shall Tenant be released from any of the obligations of this Lease because of such interference or disturbance.

23. DAMAGE BY FIRE, ETC.

23.1. In the event the Premises or the Building are damaged by fire or other cause and in Landlord’s reasonable estimation such damage can be materially restored within ninety (90) days, Landlord shall forthwith repair the same and this Lease shall remain in full force and effect, except that if such damage is not the result of any negligence or willful misconduct of Tenant or its agents, employees, or invitees, then Tenant shall be entitled to a proportionate abatement in rent from the date of such damage. Such abatement of rent shall be made pro rata in accordance with the extent to which the damage and the making of such repairs shall interfere with the use and occupancy by Tenant of the Premises from time to time. Within thirty (30) days from the date of such damage, Landlord shall notify Tenant, in writing, of Landlord’s reasonable estimation of the length of time within which material restoration can be made, and Landlord’s determination shall be binding on Tenant. For purposes of this Lease, the Building or Premises shall be deemed “materially restored” if they are in such condition as would not prevent or materially interfere with Tenant’s use of the Premises for the purpose for which it was being used immediately before such damage.

23.2. If such repairs cannot, in Landlord’s reasonable estimation, be made within ninety (90) days, Landlord and Tenant shall each have the option of giving the other, at any time within sixty (60) days after such damage, notice terminating this Lease as of the date of such damage. In the event of the giving of such notice, this Lease shall expire and all interest of the Tenant in the Premises shall terminate as of the date of such damage as if such date had been originally fixed in this Lease for the expiration of the term. In the event that neither Landlord nor Tenant exercise the above set forth option to terminate this Lease in the event of partial destruction, then Landlord shall repair or restore such damage, this Lease continuing in full force and effect, and the rent becoming due which this Lease shall be proportionately abated as provided in Section 23.1 of this Lease. Landlord shall not be required to repair or replace any damage or loss by or from fire or other cause to any panelings, decorations, partitions, additions, railings, ceilings, floor coverings, office fixtures or any other property or improvements installed on the Premises or belonging to Tenant. Any insurance which may be carried by Landlord or Tenant against loss or damage to the Building or Premises shall be for the sole benefit of the party carrying such insurance and under its sole control.

23.3. In the event that Landlord should fail to complete such repairs and material restoration within sixty (60) days after the date estimated by Landlord therefor as extended by this Section 23.3, Tenant may at its option and as its sole remedy terminate this Lease by delivering written notice to Landlord, within fifteen (15) days after the expiration of said period of time, whereupon the Lease shall end on the date of such notice or such later date fixed in such notice as if the date of such notice was the date originally fixed in this Lease for the expiration of the Term; provided, however, that if construction is delayed because of changes, deletions or additions in construction requested by Tenant, strikes, lockouts, casualties, Acts of God, war, material or labor shortages, government regulation or control or other causes beyond a reasonable control of Landlord, the period for restoration, repair or rebuilding shall be extended for the amount of time Landlord is so delayed. Notwithstanding anything to the contrary contained in this Article: (a) Landlord shall not have any obligation whatsoever to repair, reconstruct, or restore the Premises when the damages resulting from any casualty covered by the provisions of this Article 23 occur during the last twelve (12) months of the Term or any

extension thereof, but if Landlord determines not to repair such damages Landlord shall notify Tenant and if such damages shall render any material portion of the Premises untenantable Tenant shall have the right to terminate this Lease by notice to Landlord within fifteen (15) days after receipt of Landlord’s notice; and (b) in the event the holder of any indebtedness secured by a mortgage or deed of trust covering the Premises or Building requires that any insurance proceeds be applied to such indebtedness, then Landlord shall have the right to terminate this Lease by delivering written notice of termination to Tenant within fifteen (15) days after such requirement is made by any such holder, whereupon this Lease shall end on the date of such damage as if the date of such damage were the date originally fixed in this Lease for the expiration of the Term.

23.4. In the event of any damage or destruction to the Building or Premises by any peril covered by the provisions of this Article 23, it shall be Tenant’s responsibility to properly secure the Premises and upon notice from Landlord to remove forthwith, at its sole cost and expense, such portion of all of the property belonging to Tenant or its licensees from such portion or all of the Building or Premises as Landlord shall request and Tenant hereby indemnifies, protects, defends and holds Landlord harmless from any loss, liability, costs and expenses, including attorney’s fees, arising out of any claim of damage or injury as a result of any actual or alleged failure of Tenant to properly secure the Premises prior to such removal and/or such removal.

24. EMINENT DOMAIN. If all or any substantial part of the Premises shall be taken or appropriated by any public or quasi-public authority under the power of eminent domain, or conveyance in lieu of such conveyance, either party to this Lease shall have the right, at its option, of giving the order, at any time within thirty (30) days after such taking, notice terminating this Lease, except that Tenant may only terminate this Lease by reason of taking or appropriations as above provided, if such taking or appropriation shall be substantial as to materially interfere with Tenant’s use and occupancy of the Premises. If neither party to this Lease shall so elect to terminate this Lease, the rental thereafter to be paid shall be adjusted on a pro rata basis. In addition to the rights of Landlord above, if any substantial part of the Building shall be taken or appropriated by any public or quasi-public authority under the power of the eminent domain or conveyance in lieu thereof, and regardless of whether the Premises or any part thereof are so taken or appropriated, Landlord shall have the right, at its sole option, to terminate this Lease. Landlord shall be entitled to any and all income, rent, award, or any interest whatsoever in or upon any such sum, which may be paid or made in connection with any such public or quasi-public use or purpose, and Tenant hereby assigns to Landlord any interest it may have in or claim to all or any part of such sums, other than any separate award which may be made with respect to Tenant’s trade fixtures and moving expenses; Tenant shall make no claim for the value of any unexpired Term.

25. SALE BY LANDLORD. In the event of a sale or conveyance by Landlord of the Building, the same shall operate to release Landlord from any future liability upon any of the covenants or conditions, expressed or implied, contained in this Lease in favor of Tenant, and in such event Tenant agrees to look solely to the responsibility of the successor in interest of Landlord in and to this Lease. Except as set forth in this Article 25, this Lease shall not be affected by any such sale and Tenant agrees to attorn to the purchaser or assignee. If any security has been given by Tenant to secure the faithful performance of any of the covenants of

this Lease, Landlord may transfer or deliver said security, as such, to Landlord’s successor in interest and thereupon Landlord shall be discharged from any further liability with regard to said security.

26. ESTOPPEL CERTIFICATES. Within ten (10) days following any written request which Landlord may make from time to time, Tenant shall execute and deliver to Landlord or mortgagee or prospective mortgagee a sworn statement certifying: (a) the date of commencement of this Lease; (b) the fact that this Lease is unmodified and in full force and effect (or, if there have been modifications to this Lease, that this Lease is in full force and effect, as modified, and stating the date and nature of such modifications); (c) the date to which the rent and other sums payable under this Lease have been paid; (d) the fact that there are no current defaults under this Lease by either Landlord or Tenant except as specified in Tenant’s statement; and (e) such other matters as may be requested by Landlord. Landlord and Tenant intend that any statement delivered pursuant to this Article 26 may be relied upon by any mortgagee, beneficiary or purchaser and Tenant shall be liable for all loss, cost or expense resulting from the failure of any sale or funding of any loan caused by any material misstatement contained in such estoppel certificate. Tenant irrevocably agrees that if Tenant fails to execute and deliver such certificate within such ten (10) day period. Landlord or Landlord’s beneficiary or agent may execute and deliver such certificate on Tenant’s behalf, and that such certificate shall be fully binding on Tenant if Tenant fails to execute and deliver a contrary certificate within five (5) days after receipt by Tenant of a copy of the certificate so executed on behalf of Tenant.

27. SURRENDER OF PREMISES.

27.1. Tenant shall, at least thirty (30) days before the last day of the Term, arrange to meet Landlord for a joint inspection of the Premises. In the event of Tenant’s failure to arrange such joint inspection to be held prior to vacating the Premises, Landlord’s inspection at or after Tenant’s vacating the Premises shall be conclusively deemed correct for purposes of determining Tenant’s responsibility for repairs and restoration.

27.2. At the end of the Term or any renewal of the Term or other sooner termination of this Lease, Tenant will peaceably deliver up to Landlord possession of the Premises, together with all improvements or additions upon or belonging to the same, by whomsoever made, in the same conditions received or first installed, broom clean and free of all debris, excepting only ordinary wear and tear and damage by fire or other casualty.

Property not so removed shall unless requested to be removed be deemed abandoned by the Tenant and title to the same shall thereupon pass to Landlord under this Lease as by a xxxx of sale. All other alterations, additions and improvements in, on or to the Premises shall be dealt with and disposed of as provided in Article 6 hereof.

27.3. All obligations of Tenant under this Lease not fully performed as of the expiration or earlier termination of the Term shall survive the expiration or earlier termination of the Term. Upon the expiration or earlier termination of the Term, Tenant shall pay to Landlord the amount, as estimated by Landlord, reasonably necessary to repair and restore the Premises as provided in this Lease and/or to discharge Tenant’s obligation for unpaid amounts due or to become due to Landlord. All such amounts shall be used and held by Landlord for payment of such obligations of Tenant, with Tenant being liable for any additional costs upon demand by Landlord, or with any excess to be returned to Tenant after all such obligations have been determined and satisfied. Any otherwise unused Security Deposit shall be credited against the amount payable by Tenant under this Lease.

28. NOTICES.

In the event of any such relocation, Landlord will pay all expenses of preparing and decorating the new premises so that they will be substantially similar to the Premises from which Tenant is moving, and Landlord will also pay the expense of moving Tenant’s furniture and equipment to the relocated premises. In such event this Lease and each and all of the terms and covenants and conditions thereof shall remain in full force and effect and thereupon be deemed applicable to such new space except that a revised Reference Page and a revised Exhibit A shall become part of this Lease and shall reflect the location of the new premises.

If Tenant signs as a partnership, trust or other legal entity, each of the persons executing this Lease on behalf of Tenant represents and warrants that Tenant has complied with all applicable laws, rules and governmental regulations relative to its right to do business in the State of Illinois and that such entity on behalf of the Tenant was authorized to do so by any and all appropriate partnership, trust or other actions. Tenant agrees to furnish promptly upon request a corporate resolution, proof of due authorization by partners, or other appropriate documentation evidencing the due authorization of Tenant to enter into this Lease.

35. ENFORCEABILITY. If for any reason whatsoever any of the provisions of this Lease shall be unenforceable or ineffective, all of the other provisions shall be and remain in full force and effect.

36. COMMISSIONS. Each of the parties: (a) represents and warrants to the other that it has not dealt with any broker or finder in connection with this Lease, except as described on the Reference Page; and (b) indemnifies and holds the other harmless from any and all losses, liability, costs or expenses (including attorneys’ fees) incurred as a result of any alleged breach of the foregoing warranty by it.

37. TIME AND APPLICABLE LAW. Time is of the essence of this Lease and all of its provisions. This Lease shall in all respects be governed by the laws of the State of Illinois.

38. SUCCESSORS AND ASSIGNS. Subject to the provisions of Article 10, the terms, covenants and conditions contained in this Lease shall be binding upon and inure to the benefit of the heirs, successors, executors, administrators and assigns of the parties to this Lease.

39. ENTIRE AGREEMENT. This Lease, together with its exhibits, contains all agreements of the parties to this Lease and supersedes any previous negotiations. There have been no representations made by the Landlord or understandings made between the parties other than those set forth in this Lease and its exhibits. This Lease may not be modified except by a written instrument duly executed by the parties to this Lease.

40. EXAMINATION NOT OPTION. Submission of this Lease shall not be deemed to be a reservation of the Premises. Landlord shall not be bound by this Lease until it has received a copy of this Lease duly executed by Tenant and has delivered to Tenant a copy of this Lease duly executed by Landlord, and until such delivery Landlord reserves the right to exhibit and lease the

Premises to other prospective tenants. Notwithstanding anything contained in this Lease to the contrary, Landlord may withhold delivery of possession of the Premises from Tenant until such time as Tenant has paid to Landlord any security deposit required by Article 5 of this Lease, the first month’s rent as set forth in Article 3 of this Lease and any sum owed pursuant to this Lease.

41. RECORDATION. Tenant shall not record or register this Lease or a short form memorandum hereof without the prior written consent of Landlord, and then shall pay all charges and taxes incident such recording or registration.

42. LIMITATION OF LANDLORD’S LIABILITY. Redress for any claim against Landlord under this Lease shall be limited to and enforceable only against and to the extent of Landlord’s interest in the property of which the Premises are a part. The obligations of Landlord under this Lease are not intended to and shall not be personally binding on, nor shall any resort be had to the private properties of, any of its trustees or board of directors and officers, as the case may be, its investment manager, the general partners thereof, or any beneficiaries, stockholders, employees, or agents of Landlord or the investment manager.

43. RIGHT OF FIRST OFFER.

So long as this Lease is in full force and effect and free of any default on the part of Tenant hereunder, Tenant shall have the right to lease the portion of the 20th floor of the Building that is currently immediately contiguous to the Premises as shown on Exhibit A-1 attached hereto (the “Option Premises”). Except for any renewals or expansion rights of existing tenancies in the Building, Landlord agrees that prior to leasing the Option Premises to others, Landlord shall first give Tenant written notice that such space is or will become available. Such notice shall specify the rate of rent, which rate shall be the same rate that Landlord will in good faith offer the Option Premises to third parties, the effective date (the “Effective Date”) and other terms and provisions upon which Landlord is willing to add the Option Premises to the Premises leased by this Lease for the balance of the Initial Term and any Renewal Term hereof. Thereupon Tenant shall have and is hereby granted the right and option, to be exercised only by written notice given to Landlord within ten (10) days after the date of Landlord’s notice, to elect to add the Option Premises to the Premises leased by this Lease at the rate of rent and other terms and provisions specified in Landlord’s notice to Tenant; and upon timely giving of said notice, the Option Premises shall be so added to the Premises as of the Effective Date; all provided, however, that both at the date of Tenant’s notice and at the Effective Date, this Lease is in full force and effect and free of any default on the part of Tenant hereunder. In the event that Tenant elects to lease the Option Premises, Landlord shall be under no obligation to construct improvements in the Option Premises and Tenant agrees that the Option Premises shall be delivered “as is”. In the absence of timely notice from Tenant, Landlord shall have the right to lease the Option Premises to such party or parties upon and subject to such rates, period of time and other terms and provisions as Landlord shall elect, and Landlord shall not again be required to offer that available space to Tenant before so leasing it to others.

44. TERMINATION OPTION.

44.1. Provided Tenant shall not have expanded the Premises or exercised its Right of First Offer as set forth in Article 43 above, and provided Tenant shall not have taken any other

additional space in the Building or in 000 X. Xxxxxx Xxxxx, and subject as herein provided, Tenant shall have and is hereby granted the following option (“Termination Option”) to cancel and terminate this Lease as of June 30, 2001 (the “Effective Date”), but only by giving written notice of such election, to Landlord not later than September 30, 2000, which notice must be accompanied by a termination payment equal to the amount computed in accordance with the provision of Section 44.2. If Tenant fails to give said notice and make said payment by said date, Tenant will be conclusively deemed to have waived this Termination Option.

44.2. Tenant understands and agrees that in entering into this Lease, Landlord is relying upon receipt of all the Annual and Monthly Installments of Rent to become due with respect to all the Premises originally leased hereunder over the full remaining Initial Term of this Lease for amortization, including an interest factor of ten (10%) percent per annum, of the Concession Amount. For purposes hereof, the “Concession Amount” shall be defined as the aggregate of all amounts expended by Landlord under the Work Letter to this Lease (Exhibit B hereof), for brokers’ commissions incurred in connection with this Lease. Accordingly, Tenant agrees that the termination payment referred to in Section 44.1 above shall be equal to the amount (“Unamortized Amount”) of the Concession Amount determined in the same manner as the remaining principal balance of a 10% mortgage payable in level monthly payments over the same length of time, from the effectuation of the Concession Amount calculated to the end of the full Initial Term of this Lease, would be determined. To illustrate, according to a standard mortgage amortization table, the principal amount outstanding at the end of the fifth year of a loan for $100,000.00, payable in level monthly payments with interest at 10% over ten years, will be $63,042.96, assuming all payments to that point are made as due.

44.3. The Termination Option shall be and is subject to and may be exercised only if both at the date of Tenant’s notice and at the Effective Date this Lease shall be in full force and effect, free of any monetary or material other default on the part of Tenant hereunder.

45. OPTION TO RENEW.

45.1. Provided Tenant currently has no uncured default of any obligation, covenant or condition of this Lease, Tenant shall have the option to renew the Term for [***] following the Termination Date indicated on the Reference Page ([***] immediately following the Termination Date is the “Renewal Term”). The option to renew the Lease for the Renewal Term must be exercised in a written notice thereof by Tenant which must be delivered to Landlord at least [***] to the Termination Date. If the required notice to renew the Lease for the Renewal Term is not delivered by said [***] date, Tenant will be conclusively deemed to have waived this option to renew.

45.2. The rent during the Renewal Term shall be equal to the then Market Rent (as defined hereinafter) for the Premises. Written notice of Landlord’s determination of Market Rent shall be sent to Tenant within thirty (30) days after Landlord’s receipt of Tenant’s notice to renew for the Renewal Term. Unless Tenant sends Landlord a written notice within thirty (30) days after Tenant’s receipt of said determination withdrawing its exercise of its option to renew, Landlord’s determination of rent shall be conclusively binding upon the parties for the Renewal Term. If Tenant does send Landlord such written withdrawal within said thirty (30) day period, then Tenant will be conclusively deemed to have waived said option to renew.

45.3. “Market Rent” shall mean the annual rental rate then being charged by similar buildings in the area for improved space comparable to the Premises and for licenses to operate rooftop Antennae (as hereinafter defined) for leases commencing on or about the time of the applicable renewal period, taking into consideration use, location and floor level within the applicable building, the location, quality, age and reputation of the building, the definition of rentable area or net rentable area, as the case may be, with respect to which such rental rates are computed, comparative leasehold improvement, rental concessions and abatements, lease assumptions or take-overs, moving expenses, the term of the lease under consideration and the extent of services provided thereunder, applicable distinctions between “gross” leases and “net” leases, base year figures for escalation purposes, other adjustments (including, by way of example, indexes) to base rental, and any other relevant term or condition in making such evaluation.

46. LICENSE TO USE ROOFTOP SPACE.

46.1 Landlord hereby grants to Tenant a license (the “License”) to: (1) maintain and operate four (4) parabolic dish antennae (herein singularly called “Antenna” and collectively called the “Antennae”) on the roof of the Building; and (2) use, in common with others, common utility conduits and shafts currently in place within the Building and connecting the Premises to the Antennae (the locations for the Antennae and the common utility shafts and conduits being herein collectively called the “Equipment Space Area”), for the purpose of installing, operating, and maintaining the Antennae, and for connecting the Antennae to the Premises by means of coaxial or other wire or cable through the Equipment Space Area. Tenant understands that Landlord shall designate the portions or areas of the Building to be used as Equipment Space Area. Tenant’s use of the space for the Antennae licensed hereunder shall be exclusive, but Tenant’s use of the other Equipment Space Area shall be nonexclusive, and Landlord shall at all times have access to such Equipment Space Area for the purpose of operating, maintaining, repairing, or improving the Building, and Landlord may grant licenses to other tenants in the Building or others to use portions of the Equipment Space Area, other than the space for the Antennae licensed hereunder, so long as such use does not unreasonably interfere with Tenant’s use as permitted herein.

46.2. Tenant agrees to pay to Landlord, as a license fee for Tenant’s use of the Equipment Space Area, a monthly sum equal to [***] for each antennae referenced above (herein called the “Base License Fee”). The Base License Fee, if any, is payable monthly, in advance, commencing on the Commencement Date of the Lease, and thereafter on the first date of each month during the term hereof. A Base License Fee for any additional antennae (“Additional Antennae”) licensed hereunder shall be agreed to by Landlord and Tenant when and if Landlord grants Tenant permission to install Additional Antennae.

46.3. In addition to the Base License Fee, if any, Tenant shall pay to Landlord, as additional rent, on a monthly basis, the actual costs incurred by Landlord in furnishing electric power for the operation of the Antennae. Landlord and Tenant agree that Landlord shall install a meter to monitor Tenant’s use of electricity furnished by Landlord in the operation of the Antennae. All amounts due under this Article shall constitute additional rent for purposes of this Lease.

46.4. The term of this license shall be coterminous with the Initial Term of this Lease. All of the Antennae installed in the Equipment Space Area shall be and remain the property of Tenant, and Tenant shall, prior to the expiration or termination of the Lease, remove the Antennae (including all installation and anchoring hardware) and, if requested by Landlord, any cabling and other equipment used by Tenant in connection with the Antennae, and Tenant shall surrender the Equipment Space Area in substantially the same condition existing prior to the installation of the Antennae. Tenant shall be liable for, and shall promptly reimburse Landlord for, the cost of repairing all damage done to the Building by such removal, including filling and sealing any holes or cavities left by the removal of installation or anchoring hardware.

46.5. Should Landlord agree to the installation of Additional Antennae by Tenant, Tenant shall, at its sole cost and expense, and at its sole risk, install the Additional Antennae and related cabling and other equipment in a good and workmanlike manner, and in compliance with all building, electric, communications, and safety codes, ordinances, standards, regulations and requirements of the municipal, state and Federal Governments, including, without limitation, the Federal Communications Commission (the “FCC”) or any successor agency having jurisdiction over radio or telecommunications. Tenant shall deliver to Landlord Tenant’s plans and specifications for the installation of the Additional Antennae for review and approval by Landlord’s engineer not less than thirty (30) days prior to commencing installation of the Additional Antennae. Tenant shall not commence installation of the Additional Antennae without the prior written consent of Landlord (which consent shall not be unreasonably withheld or delayed), and all phases of the installation shall be under the direct supervision of Landlord. In no event shall Tenant’s installation of the Additional Antennae damage the Building or existing structures on the Building, or interfere with the maintenance of the Building, any system currently serving the Building, or any radio or telecommunications equipment currently being operated from the Building. Tenant shall notify Landlord upon completion of the installation of the Additional Antennae, and Landlord shall have ten (10) days after installation of the Additional Antennae in which to inspect the installation. Tenant shall not commence operation of the Additional Antennae until Landlord has approved the installation. Tenant’s review and approval of the plans and specifications for the installation of the Additional Antennae and Landlord’s supervision and inspection of such installation shall not be construed in any way as approval by Landlord of the adequacy or safety of the installation of the Additional Antennae or a waiver of any of Landlord’s rights hereunder, and Tenant shall be solely responsible for the adequacy and safety of the installation and operation of the Additional Antennae and solely liable for any damages or injury arising out of such installation and operation. Tenant shall pay to Landlord upon demand the cost of repairing any damage to the Building caused by such installation. The Additional Antennae shall be connected to Landlord’s power supply in strict compliance with all applicable Building, electrical, fire and safety codes. Landlord shall not be liable to Tenant for any stoppages or shortages of electrical power furnished in the Equipment Space Area because of any act, omission, or requirement of the public utility serving the Building, or the act or omission of any other tenant, licensee, or contractor of the Building, or for any other cause beyond the reasonable control of Landlord, and Tenant shall not be entitled to any abatement or offset of the Base License Fee for any such stoppage or shortage of electrical power. Notwithstanding the foregoing, Landlord acknowledges that Tenant has already installed four (4) Antennae at the Building.

46.6. Landlord agrees that Tenant shall have continuous access to the Equipment Space Area for the purpose of installing, operating, maintaining, repairing, and removing the Antennae, provided, however, that such access shall be limited to authorized engineers of Tenant, or persons under their direct supervision. Tenant shall deliver to Landlord a list of Tenant’s authorized representatives, repair, maintenance, and engineering personnel prior to any access to the Equipment Space Area, and those persons shall be required to sign in and out with Landlord’s security personnel when entering or exiting the Equipment Space Area. Landlord shall have no responsibility or liability for the conduct or safety of any of Tenant’s representatives, repair, maintenance, and engineering personnel while in any part of the Building or the Equipment Space Area, it being understood and agreed that Tenant shall be solely liable for any injury to or death of any such person from any cause resulting from the installation, operation, maintenance, repair, inspection, use, or removal of such equipment by Tenant or its agents, employees, representatives, contractors, or invitees.

46.7. Tenant shall operate the Antennae in strict compliance with Landlord’s rules and regulations, now or hereafter promulgated, and all applicable statutes, codes, rules, regulations, standards, and requirements of all Federal, state, and local governmental boards, authorities, and agencies, including, without limitation, the FCC. Tenant, prior to installing the Additional Antennae, shall have, and, shall deliver to Landlord copies of, all required permits, licenses, and consents to install and operate the Additional Antennae. The installation, operation, and maintenance of the Additional Antennae shall at all times strictly comply with the technical standards approved by Landlord. The operation of the Antennae shall not interfere with the maintenance or operation of the Building, or any system now or hereafter serving the Building, or the operation of any existing radio, microwave, satellite, or telecommunications equipment operated on or from the Building. In the event that the operation of the Antennae would violate any of the terms or conditions of this subparagraph (g), Tenant agrees to either cure such violation or suspend operation of the Antennae within forty-eight (48) hours after notice from Landlord of such violation, and not to resume operation of the Antennae until such operation is in strict compliance with all of the requirements of this subparagraph (g). In the event Tenant refuses to either cure such violation or suspend operation of the Antennae when so notified by Landlord, or in the event of an emergency, Landlord shall have the right to either cure such violation or suspend the supply of electric power to the Antennae, and Landlord shall have no liability to Tenant, and Tenant shall have no right to an abatement or offset of Base License Fees, for such suspension.

46.8. During the term hereof, Landlord reserves the right to Lease space in the Building, and to grant license for space on the roof of the Building, for the operation of radio, microwave, satellite, and telecommunications equipment by other tenants and licensees; provided, however, that such other equipment (exclusive of the equipment now situated on the roof of the Building) shall not hinder or interfere with tenants installation, operation, maintenance, or repair of the antennae.

EXHIBIT B

WORK LETTER

The undersigned, Landlord and Tenant, respectively, are executing simultaneously with this Work Letter a written Lease covering premises (the “Premises”) as described in the Lease and hereby attach this Work Letter to said Lease as Exhibit B thereto.

In consideration of the mutual covenants contained herein and in the Lease, Landlord and Tenant agree as follows:

I. Landlord Work and Plans

A. Landlord agrees to do the Work (“Landlord Work”) as shown on the drawings and specifications prepared by ASD, Inc. (the “Architect”) and ESD, the engineer dated 5/8/1996 (the “Working Drawings”), a copy of which is attached to this Work Letter as Schedule B-1, excluding any Tenant furnishings, fixtures, equipment, communications and data cabling, in electrical/data connections to Tenant’s furniture panels and systems.

B. Any subsequent modifications, provisions or changes to the Working Drawings are expressly subject to Landlord’s prior written approval.

II. Improvements

A. Landlord shall pay for all costs and expenses incurred in connection with the installation and construction of the improvements specified in the approved Working Drawings. If Tenant later requests changes, Tenant will pay the net increase in cost of the improvements as a result of such changes.

III. Tenant’s Extra Work

If Tenant requests Landlord to do any work in connection with the Premises other than the Landlord Work, or Tenant requests any modifications or changes to the Landlord Work after approval of the Working Drawings and budget therefor which increases the cost to Landlord, and Landlord, in its sole discretion, approves of such other work in writing and (such other work is hereinafter referred to as “Tenant’s Extra Work”), the following terms, conditions, agreements, and procedures shall be applicable:

B - 1

A. Tenant shall, at its sole cost and expense, cause the Architect to prepare and submit to Landlord, on or before the date construction commences (the “Plans Due Date”), all necessary drawings, plans, and specifications covering the proposed Tenant’s Extra Work (such drawings, plans and specifications are hereinafter referred to as “Tenant’s Extra Work Plans”).

B. Landlord agrees to cause Tenant’s Extra Work to be constructed, provided that Tenant’s Extra Work Plans are acceptable to Landlord and approved in writing by Landlord, that the timing of Tenant’s Extra Work must be coordinated with scheduling of the Landlord’s Work, and that Tenant has complied with all applicable provisions, terms and conditions of this Work Letter.

C. All such Tenant’s Extra Work shall be done at Tenant’s sole cost and expense. Prior to commencing any of Tenant’s Extra Work, Landlord shall submit to Tenant for Tenant’s approval a written estimate of the cost of Tenant’s Extra Work (hereinafter called the “Estimate”). If Tenant fails to approve any Estimate in writing within three (3) business days of its submission to Tenant, the Estimate shall be deemed disapproved and Landlord shall not be obligated to proceed with Tenant’s Extra Work, and Landlord may complete construction of the Landlord Work. If Tenant approves the Estimate, Landlord may require Tenant to deposit the amount of the Estimate with Landlord within three (3) business days after Landlord’s written request therefor. Such deposit shall be held as security for the payment of, and shall be credited, without interest, against the sums payable by Tenant under this Work Letter.

E. Tenant agrees to pay to Landlord the following sum for Tenant’s Extra Work:

1. All costs and expenses pertaining to Tenant’s Extra Work, subcontractors and general and other conditions, costs and expenses, and

2. An overhead charge of ten percent (10%) of the total of all such costs under paragraph III. E. 1. hereof.

Tenant shall pay to Landlord within fifteen (15) days after being billed therefor, at any time and from time to time, the amount of such costs, expenses and charges for Tenant’s Extra Work set forth in such xxxxxxxx, which amounts shall be treated as additional rent under the Lease.

B - 2

IV. Completion of the Work, Tenant’s Acts or Omissions, and Defaults

A. Landlord shall commence construction of the Landlord Work and shall tender to Tenant the Premises substantially completed on or prior to the Scheduled Commencement Date of the Lease, subject only to ordinary punch list items. Tenant shall deliver a list of such punch list items, if any, within twenty (20) days of Tenant’s occupancy of the Premises and Landlord shall complete such punch list within forty-five (45) days overreaching written agreement on such punch list items with Tenant. Landlord’s obligation to tender the Premises substantially completed on the Scheduled Commencement Date is subject to acts and events beyond Landlord’s control, including but not limited to acts of God, strikes and other occurrences of “force majeure.” During construction of the Landlord Work, Landlord shall use its best efforts to apprise Tenant of the construction schedule for the Landlord Work. In the event that the Premises are not in fact substantially completed according to such schedule, Landlord shall have a reasonable time after such date in which to take such corrective action as Landlord deems necessary and shall notify Tenant as soon as it deems such corrective action, if any, has been completed so that the Premises are ready for occupancy.

B. Notwithstanding anything in the Lease to the contrary, if Tenant is not in default hereunder or under the Lease, Tenant obligation to pay rent under the Lease shall not commence until Landlord shall have substantially completed the Landlord Work; provided, however, that if Landlord shall be delayed in substantially completing the Premises as a result of any act or omission by Tenant, its agents, employees, representatives or contractors, or any one or more of them including, without limitation, the following:

1. Tenant’s failure to approve any Estimate within three (3) business days of its submission to Tenant; or

2. Tenant’s failure to furnish to Landlord Tenant’s Extra Work Plans by the required date; or

3. Tenant’s failure to pay amounts or deposit any Estimate required hereunder within the period set forth herein; or

4. Tenant’s request for any materials, finishes, or installations other than as specified in the Working Drawings; or

5. Tenant’s request that Landlord delay or not construct the Landlord Work or Tenant’s Extra Work in all or part of the Premises; or

7. Tenant’s changes at any time or from time to time in any one or more of the following: Landlord Work, Tenant’s Extra Work, the Working

B - 3

8. The performance or completion by Tenant, for any person or entity employed by Tenant, of any work on or about the Premises including, without limitation, any disharmony or interference caused by such performance or completion as further described in paragraph V. A. hereof; or

9. Any other act or omission by Tenant or any of its agents, employees, representatives or contractors;

then, in any such event, the commencement of the term of the Lease in the payment of rent thereunder shall not be affected or deferred on account of such delay notwithstanding that the Landlord Work and/or the Tenant’s Extra Work may not be substantially completed. The cost of any changes and/or additions made to the Landlord Work, Tenant’s Extra Work, the Working Drawings, or Tenant’s Extra Work Plans at the request of Tenant after Landlord and Tenant have agreed on the Working Drawings or Tenant’s Extra Work Plans, including but not limited to the actual cost of such changes or additions, the cost of any revisions to the Working Drawings or Tenant’s Extra Work Plans, and the cost of any delays in construction resulting from any Tenant requested changes, all as determined by Landlord in its sole discretion, whether or not such changes are finally agreed to, together with ten percent (10%) of such costs for Landlord’s overhead, shall be paid by Tenant upon Landlord’s presentation of a xxxx therefor or as herein required, and such amount shall be treated as additional rent under the Lease.

B. If Tenant shall fail to comply with any term, provision or agreement here under or if Landlord and Tenant fail to reach agreement on Tenant’s Extra Work Plans within fifteen (15) days after the submission thereof to Landlord, and if any such matter is not remedied or resolved to Landlord’s satisfaction within fifteen (15) days following written notice to Tenant, then, in addition to any other remedies granted Landlord under the Lease in the case of default by Tenant and any remedies provided for elsewhere in this Work Letter or available at law or equity, Landlord may elect, upon notice to Tenant, to: (1) discontinue all work hereunder, and Tenant’s obligation to pay rent shall commence as of the Commencement Date set forth in the Lease, without any abatement on account of any delay in connection with any work relating to the Premises, (2) complete the construction of the Landlord Work pursuant to the Working Drawings as approved by Landlord and Tenant or complete any work which Landlord and Tenant have agreed to in writing, tendering possession to Tenant upon substantial completion thereof, the date of such tender being deemed to be the Commencement Date under the Lease, and charge Tenant for the additional costs of completing the electrical, plumbing, office partitions and other work, the plans and specifications for which have not been agreed to by Landlord and Tenant,

B - 4

which amount shall be paid by Tenant to Landlord as additional rent prior to any such work commencing, or (3) cancel the Lease, effective fifteen (15) days after Tenant receives notice thereof, without incurring any liability on account thereof and the term granted under the Lease is expressly limited accordingly. If Landlord cancels the Lease pursuant to the terms hereof or as a result of Tenant’s default under the Lease, such cancellation shall not affect Tenant’s liability for any sums payable hereunder.

V. Tenant’s Access to the Premises

A. After receipt of written notice from Tenant requesting access to the Premises, Landlord, in its sole discretion, may permit Tenant and Tenant’s agent’s or contractors to enter the Premises prior to the Commencement Date specified in the Lease in order that Tenant may do other approved work or alterations as may be required by Tenant to make the Premises ready for Tenant’s use and occupancy. If Landlord permits such prior entry, then such license shall be subject to the condition that Tenant and Tenant’s agents, contractors, workmen, mechanics, suppliers, and invitees shall work in harmony and not interfere with Landlord and its agents and contractors in doing their work in the Building or with other tenants and occupants of the Building. If at any time such entry shall cause or threaten to cause such disharmony or interference, Landlord, in its sole discretion, shall have the right to withdraw and cancel such license upon twenty-four (24) hours written notice to Tenant (or immediately in case of emergency or condition causing or likely to cause harm to person or property) and any further prior entry shall be prohibited. Tenant agrees that any entry into and any occupation of the Premises shall be deemed to be under all of the terms, covenants, conditions and provisions of the Lease, except as to the covenant to pay rent, and further agrees that to the extent permitted by law, Landlord and its principals, employees and agents shall not be liable in any way for any injury or death to any person or persons, loss or damage to any of Tenant’s work and installations made in the Premises, or loss or damage to property placed therein, the same being at Tenant’s sole risk. Tenant agrees to protect, defend, indemnify, and save harmless Landlord and its principals, employees and agents from all liabilities, costs, damages, fees and expenses (including reasonable attorneys’ fees and expenses) arising out of or connected with the activities of Tenant or its agents, contractors, workmen, mechanics, suppliers and invitees in or about the Premises or the Building.

B. In addition to any other conditions or limitations on such license to enter the Premises prior to the said Occupancy Date, Tenant expressly agrees that none of its agents, contractors, workmen, mechanics, suppliers, or invitees shall enter the Premises prior to the date they are tendered by Landlord unless and until each of them shall furnish such assurances to Landlord, including but not limited to, insurance coverages, waivers of lien, surety company performance bonds and personal guaranties of individuals of substance, as Landlord shall require to protect Landlord against any loss, casualty, liability, liens or claims.

B - 5

All rights and remedies of Landlord herein created or otherwise existing at law or equity are cumulative, and the exercise of one or more such rights or remedies shall not be deemed to exclude or waive the right to the exercise of any other rights or remedies. All such rights and remedies may be exercised and enforced concurrently and whenever and as often as deemed desirable.

E. Time is of the essence under this Work Letter.

F. Any person signing this Work Letter on behalf of the Tenant represents and warrants that he/she has the express authority of the Tenant to do so. Any person signing this Work Letter on behalf of Landlord represents and warrants that he/she has the express authority of Landlord to do so.

In consideration of the mutual covenants contained herein and in the Lease, Landlord and Tenant agree as follows:

I. Landlord Work and Plans

A. Landlord agrees to do the Work (“Landlord Work”) as shown on the working drawings and specifications prepared by ICL Interior Architecture dated June 25, 1997 (the “Working Drawings”), excluding any Tenant furnishings, fixtures, equipment and communications and data cabling.

B. Tenant has approved the Working Drawings.

C. The Schedule for preparation, bidding and award of the construction contract, and performance of the construction, shall be as follows:

Engineering Review		Complete
Completion of Contract Documents/ Issued for Permit		Complete
Landlord Review		Complete
Receipt of Bids		Complete
Contract Award		7/16/97
Permit Received		7/16/97
Completion of Construction		9/1/97

D. Any modifications, revisions or changes to the Plans are expressly subject to Landlord’s prior written approval.

E. Tenant acknowledges that the agreed Improvement Allowance and preliminary construction ..budget were based solely upon the Working Drawings. Accordingly, notwithstanding the final construction cost for the buildout of the tenant improvements to the Premises, Landlord shall not be required to pay more than a maximum amount of Forty-Eight Thousand Six Hundred Fifteen Dollars ($48,615.00) (equal to $15.00 psf) (the “Improvement Allowance”) for the Landlord Work, including all architectural, design, engineering and utility services, hoist fees and final cleaning. Landlord may, at its option, pay said sum directly to the contractors or may reimburse said sum to Tenant, in either case upon completion of said installation and Upon Landlord’s receipt of acceptable sworn statements and final lien waivers from the contractors; provided that Tenant has paid the entire balance of the construction cost for said improvements.

In the event Tenant fails to deliver its written disapproval of the bids within said three (3) business day period, Tenant shall be conclusively deemed to have approved them. If Tenant timely sends notice of its disapproval of the bids, the time required for such rebidding or redesigning or respecifying shall be deemed to be a Tenant Delay unless the reason for Tenant’s disapproval was, in Landlord’s reasonable opinion, the result of an error by Landlord in preparing bid specifications for the Premises. The cost of any such redesigning or respecifying shall be paid by Tenant or may be charged against any unused balance of the Improvement Allowance.

G. In rebidding the Landlord Work, Landlord will require its general contractor to obtain at least three (3) bids from each construction trade and to select the lowest qualified bidder from each such trade. Tenant shall be deemed to have approved such bids.

B. Landlord and Tenant intend, simultaneously or shortly following execution of this Fifth Amendment, to enter into a Storage Space Lease Agreement for space located in Suite 1943 on the 19^th floor containing approximately 581 rentable square feet (“Suite 1943”) for terms which are or will be co-terminus with the Term of the Lease as extended by this Fifth Amendment.

C. Landlord and Tenant desire to amend the Lease herein to extend the Term thereof, to provide for the expansion of the Premises to include additional space on the 15^th, 19^th, and 20^th Floors of the Building (collectively, the “Expansion Premises”) and to modify certain other provisions as set forth herein but not otherwise.

NOW, THEREFORE, for good and valuable consideration, the receipt and legal sufficiency of which are hereby acknowledged, Landlord and Tenant hereby agree as follows:

PART I - GENERAL PROVISIONS - EXISTING PREMISES

1. Definitions. Each capitalized term used in this Fifth Amendment shall have the same meaning as is ascribed to such capitalized term in the Lease, unless otherwise provided for herein.

2. Extension Term; Renewal Rights. The Term of the Lease is hereby extended for an additional [***] period (the “Extension Term”). The Extension Term will commence [***] (the “Extension Termination Date”). For purposes of Section 45 of the Lease (“Renewal Rights”), the Extension Termination Date shall be substituted for the “Termination Date”, thereby affording Tenant a one-time option to renew the Term for [***], subject to the terms and conditions set forth in Section 45.

3. Rent. During the Extension Term, Annual Rent for the Existing Premises and the Monthly Installments thereof shall be as set forth below, payable in the manner provided in Article 3 of the Lease:

Period	Annual Base Rent	Monthly Installment of Base Rent	Per Square Foot Annual Rent

[***]	[***]	[***]	[***]

4. Tenant’s Proportionate Share. During the Extension Term, for the purposes of determining Adjusted Monthly Base Rent pursuant to Article 4 of the Lease as amended hereby, Tenant’s Proportionate Share as set forth on the Reference Page of the Lease attributable to the Existing Premises, effective on September 1, 2003, shall be increased to 3.718% (based on a remeasured rentable area of the Building of 512,205 square feet). Tenant’s Proportionate Share will increase upon the respective “Expansion Space Commencement Date” defined below for each expansion of the Premises described below.

5. Extension of Storage Agreements. The Term of each of the Storage Agreements is hereby extended from their respective expiration dates of [***]. Notwithstanding the foregoing, it is acknowledged that the Storage Agreement dated April 30, 1999 for Suite 65 (the “Suite 65 Storage Agreement”) provides for an expiration date of [***]. Landlord and Tenant agree that the Suite 65 Storage Agreement is hereby amended to provide for a termination date of [***] as if said date had been the date for expiration of the Term thereof initially and all terms and provisions of the Suite 65 Storage Agreement that purport to apply to periods subsequent to [***] are hereby rendered null and void and of no force and effect. With respect to the remaining Storage Agreements, the “Monthly Installment of Rent” under each said Storage Agreement shall increase for the period from [***] at a rate of [***] per square foot per annum on a cumulative, compounded basis, over the Monthly Installment of Rent provided for in said Agreement for the year ending [***].

6. No Tenant Allowance. Landlord shall not provide Tenant with any tenant allowance for the Existing Premises in connection with the extension of the Term and other amendments to the Lease described in this Fifth Amendment, except to the extent expressly provided for below with respect to the Expansion Premises.

7. Condition of Premises. Tenant’s execution and delivery of this Fifth

*** Certain information on this page has been omitted and filed separately with the Securities and Exchange Commission. Confidential treatment has been requested with respect to the omitted portions.

Amendment shall be conclusive evidence that the Existing Premises are in good order and satisfactory condition as of the date hereof. No agreement of Landlord to alter, remodel, decorate, clean or improve the Existing Premises or the Building and no representation or warranty regarding the condition of the Existing Premises or the Building or regarding any other matter of any kind or nature has been made by or on behalf of Landlord to Tenant under or by reason of this Fifth Amendment.

8. Improvements Required For Existing and Expansion Premises; Suite 1943 and Rooftop. Landlord and Tenant acknowledge that Tenant is required to install certain improvements (the “Roof and Suite 1943 Improvements”) in Suite 1943 and on the roof of the Building to accommodate Tenant’s mechanical, electrical and heating, ventilating and cooling needs for the Existing Premises and the New Premises. The major components of such improvements include four (4) rooftop HVAC units and various transformers, ups units, batteries and other equipment to be installed in Suite 1943. All plans, specifications and working drawing for any work to be performed to install the Roof and Suite 1943 Improvements (the “Plans”) shall be submitted to Landlord for review. Landlord shall have the right to disapprove the Plans or to require modifications thereto as are reasonable in light of the equipment to be installed and work to be performed, which modifications may include the installation of additional structural support to Suite 1943 as is necessary to support loads created by the improvements to be installed. Landlord shall have five (5) business days following the delivery of the Plans to approve or disapprove same, and, if disapproved, to require modifications thereto as reflected above. If disapproved, Tenant shall make the required modifications to the Plans and shall resubmit them to Landlord in accordance with the foregoing procedure. Tenant has agreed to bear all costs associated with the preparation of the Plans, the Roof and Suite 1943 Improvements, and the work required to install such improvements at Tenant’s sole cost and expense and to engage ESD as the engineer to prepare systems plans for such improvements. If requested by Landlord by written notice to Tenant given not less than six (6) months prior to the Extension Termination Date, Tenant, prior to the expiration of the Term, shall remove the Roof and Suite 1943 Improvements and all cabling, hardware and other equipment associated therewith, regardless of whether installed in the Existing Premises, the Expansion Premises or any computer rooms located therein, and Tenant shall surrender all rooftop areas and Suite 1943 in substantially the same condition as existed prior to the installation of the Roof and Suite 1943 Improvements. Tenant shall be liable, and shall promptly reimburse Landlord for, the cost of repairing all damage done to the Building by the installation, removal or failure to remove such improvements, including filling and sealing of any holes or cavities created by the removal thereof. All other provisions of the Lease requiring Tenant to provide insurance to and indemnify Landlord against risks associated with the use of the Premises shall apply to the rooftop area used by Tenant and to the Roof and Suite 1943 Improvements and Tenant agrees to fully comply with the requirements of any warranty or guaranty affecting the roof of the Building.

10. Real Estate Broker. Tenant represents that Tenant has not dealt with any real estate broker, salesperson or finder in connection with this Fifth Amendment and no such person initiated or participated in the negotiation of this Fifth Amendment or is entitled to any fee or commission in connection herewith. Tenant hereby agrees to indemnify and hold Landlord, its property manager and their respective agents and employees harmless from and against any and all damages, liabilities, claims, actions, costs and expenses (including attorneys’ fees) arising from either (i) any claims or demands of any broker, salesperson or finder for any fee or commission alleged to be due such broker, salesperson or finder in connection with this Fifth Amendment or (ii) a claim of, or right to, any lien under the Statutes of the State of Illinois relating to real estate broker liens with respect to any such broker, salesperson or finder retained by Tenant.

11. Te1ecommunications Riser. Tenant has requested that Landlord install an additional telecommunications riser in the Building to service Tenant’s (and possibly other tenants) telecommunications needs. Landlord has not agreed to install any such riser, but hereby agrees to work with Tenant in good faith to develop a joint plan to service Tenant’s present and future telecommunications needs, including the sharing of costs associated with the installation or use of any new riser or improvements to the existing riser. In addition, Landlord may impose reasonable usage fees associated with Tenant’s use of the existing or any newly constructed riser. The foregoing, however, shall not be deemed to impose on Landlord any affirmative or implied obligation to construct or install such new riser or other improvements.

12. Expansion of Right of First Offer. Section 43 of the Lease is hereby amended to add to the “Option Premises” (as defined therein) any space which becomes available for leasing which is outside of the Premises and the Expansion Premises and is located on the eleventh (11^th) through the twenty-first (21^st) floors of the Building, subject to the rights and limitations on Tenant’s right of first offer to lease such additional portions of the Option Premises set forth in Section 43. In particular, no space will be deemed “available for leasing” pursuant to Section 43 of the Lease if such space is subject to a right or option to lease set forth in or granted under any other lease in the Building unless and until such right or option set forth in such other lease has expired by its terms without being exercised by the tenant granted such right.

WORKLETTER AGREEMENT

THIS WORKLETTER AGREEMENT (“Workletter”) is executed simultaneously with that certain Fifth Amendment to Lease between Xxxxxxxx Analytics, Ltd., as Tenant, and Xxxxxxx-Xxxxxxx Hartford, L.L.C., as Landlord (the “Fifth Amendment”), relating to certain “Expansion Premises” (as defined in the Fifth Amendment), which are further defined in the Fifth Amendment as the 15^th Floor Premises”, the “19^th Floor Premises”, and the “20^th Floor Premises”) located at the building commonly known as 000 Xxxxx Xxxxxx Xxxxx, Xxxxxxx, Xxxxxxxx (“Building”). For purposes of this Workletter, the “Premises”, if used without further definition, shall mean and refer to that portion of the Work (defined below) associated with the respective three areas of the Expansion Premises referred to above. Capitalized terms used herein, unless otherwise defined in this Workletter, shall have the respective meanings assigned to them in the Fifth Amendment or the remainder of the Lease; provided that in the event of any conflict between the terms and provisions of the Fifth Amendment and the terms and provisions of the remainder of the Lease, the terms and provisions of the Fifth Amendment shall prevail.

For and in consideration of the agreement to lease the demised premises and the mutual covenants contained herein and in the Lease, Landlord and Tenant hereby agree as follows:

1. Acceptance of Premises. Tenant has agreed to accept the Premises in its current “as is” Condition in order to perform the “Work” (defined below) therein.

2. Work. Tenant, at its sole cost and expense (subject to Landlord’s obligation to fund Landlord’s Contribution), shall perform or cause to be performed the work (the “Work”) in the Premises provided for in the Plans (as defined in Paragraph 3 hereof) submitted to and approved by Landlord. Tenant’s Work shall be constructed in a good and workmanlike fashion, in accordance with the requirements set forth herein and in compliance with all applicable laws, ordinances, rules and other governmental requirements. Tenant shall commence the construction of the Work promptly following completion of the preconstruction activities provided for in Paragraph 3 below and shall diligently proceed with all such construction. Tenant shall coordinate its Work so as avoid interference with any other work being performed by or on behalf of Landlord and other tenants at the Building.

3. Preconstruction Activities.

A. (I) as to the 15^th Floor Premises and the 19^th Floor Premises, on or before July 30, 1999, and (II) as to the 20th Floor Premises, on or before the delivery of occupancy of such premises to Tenant, Tenant shall submit the following information and items to Landlord for Landlord’s review

and approval:

(i) a detailed construction schedule containing the major components of the Work and the time required for each, including the scheduled commencement date of construction of the Work, milestone dates and the estimated date of completion of construction;

(ii) an itemized statement of the estimated construction cost, including permits and architectural and engineering fees;

(iii) evidence satisfactory to Landlord of Tenant’ s ability to pay the cost of the Work in excess of Landlord’s Contribution for such portion of the Premises, if any, as and when payments become due.

(iv) the names and addresses of Tenant’s contractors (and the contractors’ subcontractors) to be engaged by Tenant for the Work (“Tenant’s Contractors”). Landlord has the right to reasonably approve or reasonably disapprove Tenant’s Contractors. Tenant shall not employ as Tenant’s Contractors any persons or entities disapproved by Landlord. If Landlord has affirmatively approved only certain contractor(s) and/or subcontractor(s) from Tenant’s list, Tenant shall employ as Tenant’s Contractors only those persons or entities so approved. Landlord may, at its election, designate a list of approved contractors for performance of work involving electrical, mechanical, plumbing or life-safety systems, from which Tenant must select its contractors for such work;

(v) certified copies of insurance policies or certificates of insurance as hereinafter described. Tenant shall not permit Tenant’s Contractors to commence work until the required insurance has been obtained and certified copies of policies or certificates have been delivered to Landlord; and

(vi) the Plans for the Work, which Plans shall be subject

to Landlord’s approval in accordance with Paragraph 3(B) below.

Tenant will update such information and items by notice to Landlord of any changes.

B. As used herein, the term “Plans” shall mean full and detailed architectural and engineering plans and specifications covering the Work (including, without limitation, architectural, mechanical and electrical working drawings for the Work). The Plans shall include the minimum information shown on Attachment B attached hereto and incorporated herein. The Plans shall be subject to Landlord’s approval and the approval of all local governmental authorities requiring approval, if any. Landlord shall give its approval or disapproval (giving general reasons in case of disapproval) of the Plans within five (5) business days after receipt thereof by Landlord. Landlord agrees not to unreasonably withhold its approval of said Plans; provided, however, that Landlord shall not be deemed to have acted unreasonably if it withholds it consent because, in Landlord’s opinion: (i) the Work is likely to affect adversely Building systems, the structure of the Building or the safety of the Building and its occupants; (ii) the Work would increase Landlord’s ability to furnish services to Tenant or other tenants; (iii) the Work would increase the cost of operating the Building; (iv) the Work would violate any governmental laws, rules or ordinances; (v) the Work contains or uses hazardous or toxic materials; (vi) the Work would adversely affect the appearance of the Building; (vii) the Work would adversely affect another tenant’s premises; or (viii) the Work is prohibited by any mortgage on the Building. The foregoing reasons, however, shall not be exclusive of the reasons for which Landlord may withhold consent, whether or not such other reasons are similar to or dissimilar from the foregoing. Landlord shall cooperate with Tenant by discussing or reviewing preliminary plans and specifications, at Tenant’s request prior to completion of the full, final detailed Plans, in order to expedite preparation of the final Plans and the approval process. If Landlord notifies Tenant that changes are required to the final Plans submitted by Tenant, Tenant shall, within three (3) days thereafter, submit to Landlord for its approval the Plans as amended in accordances with the changes so required. The Plans shall also be revised, and the Work shall be changed, to incorporate any work

required in the Premises by any local governmental field inspector. Landlord’s approval of the Plans shall in no way be deemed to be acceptance or approval of any element therein contained which is in violation of any applicable laws, ordinances, regulations or other governmental requirements.

C. No Work shall be undertaken or commenced by Tenant in the Premises until:

(i) the Plans have been submitted to and approved by Landlord;

(ii) all necessary building permits have been obtained by Tenant;

(iii) all required insurance coverages have been obtained by Tenant. (Failure of Landlord to receive evidence of such coverage upon commencement of the Work shall not waive Tenant’s obligations to obtain such coverages.);

(iv) items required to be submitted to Landlord prior to commencement of construction of the Work have been so submitted and have been approved, where required; and

(v) Landlord has given written notice that the Work can proceed, subject to such reasonable conditions as Landlord may impose.

4. Delays. In the event Tenant fails to deliver or deliver in sufficient and accurate detail the information required under Paragraph 3 on or before the respective dates specified in said Paragraph, or in the event Tenant, for any reason, fails to complete the Work on or before the scheduled commencement date of the term of the Lease for such portion of the Premises, Tenant shall be responsible for rent and all other obligations as set forth in the Lease as to such portion of the Premises from the scheduled date for the commencement date under the Fifth Amendment, regardless of the degree of completion of the Work on such date, and no such delay in completion of the Work shall relieve Tenant of any of its obligations under the Lease.

5. Charges and Fees. Subject to Paragraph 9 below, Tenant shall be responsible for all costs and expenses attributable to the Work.

6. Change Orders. All changes to the final Plans requested by Tenant must be approved by Landlord in advance of the implementation of such changes as part of the Work. All delays caused by Tenant-initiated change orders, including, without limitation, any stoppage of work during the change order review process, are solely the responsibility of Tenant and shall cause no delay in the commencement of the Lease or the rental and other obligations therein set forth.

7. Standards of Design and Construction and Conditions of Tenant's Performance. All work done in or upon the Premises by Tenant shall be done according to the standards set forth in this Paragraph 7, except as the same may be modified in the Plans approved by or on behalf of Landlord and Tenant.

A. Tenant’s Plans and all design and construction of the Work shall comply with all applicable statutes, ordinances, regulations, laws, codes and industry standards, including, but not limited to, requirements of Landlord’s fire insurance underwriters. Approval by Landlord of the Plans shall not constitute a waiver of this requirement or assumption by Landlord of responsibility for compliance. Where several sets of the foregoing laws, codes and standards must be met, the strictest shall apply where not prohibited by another law, code or standard.

B. Tenant shall obtain, at its own cost and expense, all required building permits and, when construction has been completed, shall obtain, at its own cost and expense, an occupancy permit for the Premises, which permit shall be delivered to Landlord. Tenant’s failure to obtain such permits shall not cause a delay in the commencement of the Lease or the rental and other obligations therein set forth.

C. Tenant’s Contractors shall be licensed contractors, possessing good labor relations, capable of performing quality workmanship and working in harmony with Landlord’s contractors and subcontractors and with other contractors and subcontractors in the Building. All work shall be coordinated with any other construction or other work in the Building in order not to affect adversely construction work being performed by or for Landlord or its tenants, it being understood that, in the event of any conflict, Landlord and its contractors and subcontractors shall have priority over Tenant and Tenant’s Contractors.

D. Landlord shall have the right, but not the obligation, to perform on behalf of and for the account of Tenant, subject to reimbursement by Tenant, any work (i) which Landlord deems to be necessary on an emergency basis, (ii) which pertains to structural

components, building systems or the general utility systems for the Building, (iii) which pertains to the erection of temporary safety barricades or signs during construction, or (iv) which pertains to patching of the Work and other work in the Building.

E. Tenant shall use only new, first-class materials in the Work, except where explicitly shown otherwise in the Plans approved by Landlord and Tenant. Tenant shall obtain warranties of at least one (1) year’s duration from the completion of the Work against defects in workmanship and materials on all work performed and equipment installed in the Premises as part of the Work.

F. Tenant and Tenant’s Contractors, in performing work, shall not interfere with other tenants and occupants of the Building. Tenant and Tenant’s Contractors shall make all efforts and take all steps appropriate to construction activities undertaken in a fully occupied, first-class office building so as not to interfere with the operation of the Building and shall, in any event, comply with all reasonable rules and regulations existing from time to time at the Building. Tenant and Tenant’s Contractors shall take all precautionary steps to minimize dust, noise and construction traffic and to protect their facilities and the facilities of others affected by the Work and to properly police same. Construction equipment and materials are to be kept within the Premises, and delivery and loading of equipment and materials shall be done at such locations and at such time as Landlord shall direct so as not to burden the construction or operation of the Building.

G. Landlord shall have the right to order Tenant or any of Tenant’s Contractors who violate the requirements imposed on Tenant or Tenant’s Contractors in performing work to cease work and remove its equipment and employees from the Building. No such action by Landlord shall delay the commencement of the Lease or the rental and other obligations therein set forth.

H. Utility costs or charges for any service (including HVAC, hoisting or freight elevator and the like) to the Premises shall be the responsibility of Tenant from the date Tenant is obligated to commence or commences the Work and shall be paid for by Tenant at Landlord’s rates. Tenant shall apply and pay for all utility meters required. Tenant shall pay for all support services provided by Landlord’s contractors. All use of freight elevators is subject to scheduling by Landlord. Tenant shall arrange and pay for removal of construction debris and shall not place debris in the Building’s waste containers.

I. Tenant shall permit access to the Premises, and the Work shall be subject to inspection, by Landlord and Landlord’s architects,

engineers, contractors and other representatives at all times during the period in which the Work is being constructed and installed and following completion of the Work.

J. Tenant shall proceed with its work expeditiously, continuously and efficiently, and shall complete the same as and when provided for in the Fifth Amendment and this Workletter. Tenant shall notify Landlord upon completion of the Work and shall furnish Landlord and Landlord’s title insurance company with such further documentation as may be necessary under Paragraph 9 below.

K. Tenant shall have no authority to deviate from the Plans in performance of the Work, except as authorized by Landlord and its designated representative in writing. Tenant shall furnish to Landlord “as-built” drawings of the Work within sixty (60) days after completion of the Work.

L. Landlord shall have the right to run utility lines, pipes, conduits, duct work and component parts of all mechanical and electrical systems where necessary or desirable through the Premises, to repair, alter, replace or remove the same, and to require Tenant to install and maintain proper access panels thereto.

M. Tenant shall impose on and enforce all applicable terms of this Workletter Agreement against Tenant’s architect and Tenant’s Contractors.

8. Insurance and Indemnification.

A. In addition to any insurance which may be required under the Lease, Tenant shall secure, pay for and maintain or cause Tenant’s Contractors to secure, pay for and maintain during the continuance of construction and fixturing work within the Building or Premises, insurance in the following minimum coverages and limits of liability:

(i) workers’ compensation and employers’ liability insurance with limits of not less than $500,000.00, or such higher amounts as may be required from time to time by any employee benefit acts or other statutes applicable where the work is to be performed, and in any event sufficient to protect Tenant’s Contractors from liability under the aforementioned acts;

(ii) comprehensive or commercial general liability insurance (including contractors’ protective liability) in an amount not less than $2,000,000.00 per

occurrence, whether involving bodily injury liability (or death resulting therefrom) or property damage liability or a combination thereof with a minimum aggregate limit of $2,000,000.00, and with umbrella coverage with limits not less than $10,000,000.00. Such insurance shall provide for explosion and collapse, completed operations coverage and broad form blanket contractual liability coverage and shall insure Tenant’s Contractors against any and all claims for bodily injury, including death resulting therefrom, and damage to the property of others and arising from its operations under the contracts whether such operations are performed by Tenant’s Contractors or by anyone directly or indirectly employed by any of them;

(iii) comprehensive automobile liability insurance, including the ownership, maintenance and operation of any automotive equipment, owned, hired or nonowned, in an amount not less than $500,000.00 for each person in one accident and $1,000,000.00 for injuries sustained by two or more persons in any one accident, and property damage liability in an amount not less than $1,000,000.00 for each accident. Such insurance shall insure Tenant’s Contractors against any and all claims for bodily injury, including death resulting therefrom, and damage to the property of others arising from its operations under the contracts, whether such operations are performed by Tenant’s Contractors or by anyone directly or indirectly employed by any of them;

(iv) “all risk” builder’s risk insurance upon the entire Work to the full insurable value thereof. This insurance shall include the interests of Landlord and Tenant (and their respective contractors and’ subcontractors of any tier to the extent of any insurable interest therein) in the Work and shall insure against the perils of fire and extended coverage, and shall include “all risk” builder’s risk insurance for physical loss or damage including, without duplication of coverage, theft, vandalism and malicious mischief. If portions of the Work are stored off the site of the Building or in transit to said site are not covered under said “all risk” builder’s risk insurance, then Tenant shall effect and maintain

similar property insurance on such portions of the Work. Any loss insured under said “all risk” builder’s risk insurance is to be adjusted with Landlord and Tenant and made payable to Landlord as trustee for the insureds, as their interests may appear.

All policies (except the workers compensation policy) shall be endorsed to include as additional insured parties Landlord and its beneficiaries, their partners, directors, officers, employees and agents, Landlord’s contractors, Landlord’s architects, and such additional persons as Landlord may designate. The waiver of subrogation provisions contained in the Lease shall apply to all insurance policies (except the workers’ compensation policy) to be obtained by Tenant pursuant to this Paragraph. The insurance policy endorsements shall also provide that all additional insured parties shall be given thirty (30) days’ prior written notice of any reduction, cancellation or nonrenewal of coverage (except that ten (10) days’ notice shall be sufficient in the case of cancellation for nonpayment of premium) and shall provide that the insurance coverage afforded to the additional insured parties thereunder shall be primary to any insurance carried independently by said additional insured parties. Additionally, where applicable, each policy shall contain a cross-liability and severability of interest clause.

B. Without limitation of the indemnification provisions contained in the Lease, to the fullest extent permitted by law Tenant agrees to indemnify, protect, defend and hold harmless Landlord, Landlord’s contractors and Landlord’s architects and their partners, directors, officers, employees and agents, from and against all claims, liabilities, losses, damages and expenses of whatever nature arising out of or in connection with the Work or the entry of Tenant or Tenant’s Contractors into the Building and the Premises, including, without limitation, mechanics’ liens or the cost of any repairs to the Premises or Building necessitated by activities of Tenant or Tenant’s Contractors and bodily injury to persons (including, to the maximum extent provided by law, claims arising under the Illinois Structural Work Act) or damage to the property of Tenant, its employees, agents, invitees or licensees or others. It is understood and agreed that the foregoing indemnity shall be in addition to the insurance requirements set forth above and shall not be in discharge of or in substitution for same or any other indemnity or insurance provision of the Lease.

9. Landlord’s Contribution; Excess Amounts.

A. Upon completion of the Work, Tenant shall furnish Landlord with final waivers of Liens and contractors’ affidavits, in such form as may be required by Landlord, from all parties performing labor or supplying materials or services in connection with the Work showing that all of said parties have been compensated in full and waiving all liens in connection with the Premises and Building. Tenant shall submit to

Landlord a detailed breakdown of Tenant’s total construction costs, together with such evidence of payment as is reasonably satisfactory to Landlord.

B. Upon completion of the Work and Tenant’s satisfaction of all requirements set forth herein, Landlord promptly shall make a dollar contribution in the amount attributable to the portion of the Premises so completed, as specified in the Fifth Amendment (“Landlord’s Contribution”) (each of which is Fourteen Dollars ($14.00) per square foot of rentable area of such portion of the Premises) for application to the extent thereof to the cost of the Work. If the cost of the Work exceeds Landlord’s Contribution, Tenant solely shall have responsibility for the payment of such excess cost. If the cost of the Work is less than Landlord’s Contribution, Tenant shall be entitled to an offsetting credit against the first installment(s) of Base Rent due under the Lease for the applicable portion of the Premises until such excess amount has been utilized. Notwithstanding anything herein to the contrary, Landlord may deduct from Landlord’s Contribution any amounts due to Landlord or its architects or engineers under this Workletter, if any.

10. Miscellaneous.

A. Except as expressly set forth herein or in the Lease, Landlord has no agreement with Tenant and has no obligation to do any work with respect to the Premises.

B. If the Plans for the Work require the construction and installation of more fire hose cabinets or telephone/electrical closets than the number regularly provided by Landlord in the core of the Building in which the Premises are located, then Tenant agrees to pay all costs and expenses arising from the construction and installation of such additional fire hose cabinets or telephone/electrical closets.

C. Time is of the essence under this Workletter.

D. Any person signing this Workletter on behalf of Landlord and/or Tenant warrants and represents he has authority to do so.

E. If Tenant fails to make any payment relating to the Work as required hereunder, Landlord, at its option, may complete the Work pursuant to the approved Plans and continue to hold Tenant liable for the costs thereof and all other costs due to Landlord. Tenant’s failure to pay any amounts owed by Tenant hereunder when due or Tenant's failure to perform its obligations hereunder shall also constitute a default under the Lease, and Landlord shall have all the rights and remedies granted to

Landlord under the Lease for nonpayment of any amounts owed thereunder or failure by Tenant to perform its obligations thereunder.

F. Notices under this Workletter shall be given in the same manner as under the Lease.

G. The liability of Landlord hereunder or under any amendment hereto or any instrument or document executed in connection herewith (including, without limitation, the Lease) shall be limited to and enforceable solely against Landlords interest in the Building.

H. The headings set forth herein are for convenience only.

I. This Workletter sets forth the entire agreement of Tenant and Landlord regarding the Work. This Workletter may only be amended if in writing and duly executed by both Landlord and Tenant.

SIXTH AMENDMENT TO LEASE

THIS SIXTH AMENDMENT TO LEASE (“Sixth Amendment”) is made as of the 27^th day of August, 1999, by and among XXXXXXX-XXXXXXX HARTFORD, L.L.C., a Delaware limited liability company (“Landlord”), and XXXXXXXX ANALYTICS, LTD., an Illinois corporation (“Tenant”).

WITNESSETH:

A. Landlord’s predecessor-in-interest and Tenant entered into a certain lease dated as of June 3, 1996, as amended by a letter agreement dated August 28, 1996 and by Amendments dated as of December 20, 1996, July 17, 1997, July 31, 1998, November 12, 1998 and July 1, 1999 (said July 1, 1999 Amendment being referred to herein as the “Fifth Amendment”) (the original Lease, as amended by such letter agreement and Amendments is referred to herein as the “Lease”), whereby Landlord’s predecessor-in-interest or Landlord leased to Tenant certain premises consisting of Suite Nos. 1550 (11,828 rental square feet), 1925 (9,393 rental square feet), 2000 (4,215 rental square feet), 2040 (9,939 rentable square feet), 2012 (3,241 rentable square feet), 2020 (2,852 rentable square feet) and 2015 (3,010 rentable square feet) (collectively, the “Existing Premises”) on the fifteen (15th), nineteenth (19^th) and twentieth (20^th) floor of the building located at 000 Xxxxx Xxxxxx Xxxxx, Xxxxxxx, Xxxxxxxx 00000 (the “Building”) for a term expiring on August 31, 2006. Landlord has also entered into various Storage Space Lease Agreements dated October 13, 1997 (Suite 2045-587 rentable square feet), December 15, 1997 (Suite 2017-120 rentable square feet), January 14, 1998 (Suite 2023-318 rentable square feet), April 30, 1999 (Suite 65-846 rentable square feet) and July 1, 1999 (suite 1943 - 581 rental square feet) (collectively, the “Storage Agreements”).

B. Landlord and Tenant desire to amend the Lease herein to provide for the expansion of the Premises to include additional space consisting of 2,033 rental square feet of space located on the 20^th Floor of the Building depicted on Exhibit A attached hereto (the “Suite 2010 Premises”) and to modify certain other provisions as set forth herein but not otherwise.

NOW, THEREFORE, for good and valuable consideration, the receipt and legal sufficiency of which are hereby acknowledged, Landlord and Tenant hereby agree as follows:

1. Subject to the provisions of Section 5 below, Landlord hereby leases to Tenant and Tenant hereby leases from Landlord, Suite 2010, consisting of 2,033 rentable square feet as outlined on Exhibit A hereto and commonly known as Suite 2010 for a term commencing as set forth below and terminating on August 31, 2006 (subject to the renewal rights of Tenant set forth in the Lease) (the “Suite 2010 Term”). Upon delivery of the Suite 2010 Premises to Tenant as provided below, such space shall become part of the “Premises” under the Lease.

2. Base Rent payable for the Suite 2010 Premises during the Suite 2010

Term shall be as set forth in Exhibit B to this Sixth Amendment. Said Base Rent, together with all Additional Rent payable under the Lease, shall be payable in advance on the first day of each calendar month. Base Rent for any partial month shall be prorated on the basis of the number of days of such calendar month falling within the Suite 2010 Term.

3. Tenant shall complete any and all work required to be performed in the Suite 2010 Premises for occupancy thereof by Tenant (the “Work”) at Tenant’s sole cost and expense (except for Landlord’s Contribution, defined below). The Work shall be designed and performed in accordance with the Workletter attached as Exhibit C to the Fifth Amendment (the “Workletter”), except that Tenant hereby agrees to cause to be prepared by an architect or engineer acceptable to Landlord all plans and drawings associated with the Work and to submit all “Plans” (as defined in said Workletter) for the Work to Landlord for prior approval. Landlord shall have a period of five (5) business days to review and provide comments to the Plans. Rent for the Suite 2010 Premises shall commence upon the earlier to occur of (a) the date on which substantial completion of the Work associated with the Suite 2010 Premises occurs or is deemed to occur as specified in the Workletter, or (b) the expiration of eight (8) weeks following the date on which Landlord delivers occupancy of the Suite 2010 Premises to Tenant for performance of the Work (such earlier date being the “Suite 2010 Commencement Date”); provided, however, that in the event the nature of the Work is such that Landlord determines that abatement of any asbestos-containing materials is required, Landlord shall perform such abatement (a) as expeditiously as is commercially reasonable, and (b) at Landlord's sole cost and expense, and the time period Landlord is required to occupy the Suite 2010 Premises after commencement of the Work to perform such abatement shall not be included in the eight (8) week period described above. Landlord hereby agrees to pay Twenty Eight Thousand Four Hundred Sixty Two and no/100 Dollars ($28,462.00) (based on $14.00 per square foot) for the Work to be performed in the Suite 2010 Space, (“Landlord’s Suite 2010 Contribution”), which shall be used for the cost and expense of the Work and architectural and space planning fees associated therewith. In the event less than all of Landlord’s Suite 2010 Contribution is paid in connection with the Work, any unused portion thereof shall be credited to Tenant against the first payment(s) of Base Rent payable for the Suite 2010 Premises.

4. As of the date Rent commences for the Suite 2010 Premises, Tenant’s Proportionate Share under the Lease will increase by 0.397%.

5. Notwithstanding anything to the contrary set forth above, the foregoing rights and obligations of Landlord and Tenant with respect to the Suite 2010 Premises are subject to (a) the current tenant occupying Suite 2008 (1,500 rentable square feet of space) vacating such space; (b) Landlord’s ability to terminate the lease of the current tenant (American Trading Group, L.P.) of Suite 2010 (533 rentable square feet of space) in the Building (the “American Trading Lease”) on terms reasonably acceptable to Landlord and American Trading Group, L.P. and (c) Tenant’s agreement, and furnishing to Landlord of adequate security for Tenant’s commitment, to pay any and all termination payments required to be paid to such tenant in connection with Landlord’s termination of the American Trading Lease, to the extent not in excess of $25,000. It is currently anticipated that such termination of the American Trading Lease will require payments of $12,500 upon execution of a Lease Termination Agreement between Landlord and American

Trading Group, L.P and $12,500 upon vacation and surrender of its space. Accordingly, for purposes of the foregoing, “adequate security” will be deemed to mean (i) deposit by Tenant with Landlord of a check payable to American Trading Group, L.P. representing good funds in the amount of $12,500.00 (the “Initial Deposit”) upon execution of this Sixth Amendment, and (ii) Tenant’s agreement to tender to American Trading Group, L.P. the remaining required termination payment (the “Final Deposit”, which shall not be in excess of an additional $12,500) prior to the date required to be paid by Landlord to American Trading Group, L.P. In the event Tenant fails to pay the Final Deposit within five (5) days following written demand from Landlord, Landlord shall be entitled immediately to reduce Landlord’s Suite 2010 Contribution by any amount unpaid by Tenant. Landlord covenants to use the Initial Deposit and the Final Deposit to make required termination payments as described above and to refund the Initial Deposit to Tenant if it is unable to secure a Lease Termination Agreement with American Trading Group, L.P. on terms consistent with the foregoing prior to August 27, 1999.

6. Submission. Submission of this Sixth Amendment by Landlord or Landlord's agent, or their respective agents or representatives, to Tenant for examination and/or execution shall not in any manner bind Landlord and no obligations on Landlord shall arise under this Sixth Amendment unless and until this Sixth Amendment is fully signed and delivered by Landlord and Tenant.

7. Binding Effect; Conflict. The Lease, as amended hereby, shall continue in full force and effect, subject to the terms and provisions thereof and hereof. In the event of any conflict between the terms of the Lease and the terms of this Sixth Amendment, the terms of this Sixth Amendment shall control. This Sixth Amendment shall be binding upon and inure to the benefit of Landlord, Tenant and their respective successors and permitted assigns.

8. Consent to Subleases. Landlord acknowledges that Tenant may elect, from and after the date Tenant has commenced paying Rent with respect to the Suite 2010 Premises, to sublease portions of the Suite 2010 Premises to Terra Nova Trading, L.L.C. and/or Archipelago Holdings, L.L.C., each of which is an affiliate of the principals of Tenant, or their respective subsidiaries or affiliates. As set forth in Part 3, paragraph 3 of the Fifth Amendment, a sublease or subleases of not more than fifty percent (50%) of the aggregate square footage of the Premises (including the Suite 2010 Premises) to such entities shall be permitted without the consent of, but with not less than thirty (30) days’ prior written notice to, Landlord.

9. Limitation of Liability. Neither Landlord nor any officer, director, member or employee of Landlord nor any owner of the Building, whether disclosed or undisclosed, shall have any personal liability with respect to any of the provisions of the Lease, as hereby amended, or the Premises, and if Landlord is in breach or default with respect to Landlord’s obligations under the Lease, as hereby amended, or otherwise, Tenant shall look solely to the equity interest of Landlord in the Building for the satisfaction of Tenant’s remedies or judgments.

IN WITNESS WHEREOF, this Sixth Amendment is executed as of the day and year aforesaid.

WITNESSETH:

B. Landlord and Tenant desire to amend the Lease to expand the Premises within the Building for a term not to exceed six (6) months and to modify certain other provisions as set forth herein but not otherwise.

NOW, THEREFORE, for good and valuable consideration, the receipt and legal sufficiency of which are hereby acknowledged, Landlord and Tenant hereby agree as follows:

1. Definitions. Each capitalized term used in this Ninth Amendment shall have the same meaning as is ascribed to such capitalized term in the Lease, unless otherwise provided for herein.

The Suite 1730 Expansion Space shall be leased for a six (6) month term ending on March 31, 2001, subject to early termination by either Landlord or Tenant effective on the last day of any month upon not less than thirty (30) days’ prior written notice to the other party. The last day of the term for the

3. Reduction of Size of Premises. Commencing on the day after the Suite 1730 Termination Date (the “Reduction Effective Date”), the size of the Premises shall be reduced by eliminating that portion of the Premises consisting of the Suite 1730 Expansion Space (such eliminated space being referred to herein as the “Reduction Space”), such that the total rentable square footage of the Premises shall be fifty-seven thousand nine hundred fifty-seven (57,957) rentable square feet.

4. Obligations for Reduction Space. Prior to the Reduction Effective Date, Tenant shall (a) remove all Tenant’s trade fixtures and property from the Reduction Space; (b) repair any damage to the Reduction Space caused thereby; (c) surrender the Reduction Space and all keys thereto to Landlord; and (d) perform as to the Reduction Space all other activities specified in the Lease upon surrender of the Premises. Tenant shall be liable to Landlord for all costs and expenses incurred by Landlord as a result of Tenant’s failure to perform any of the foregoing. Any retention of possession by Tenant of all or part of the Reduction Space after the Effective Date shall be deemed a holding over under Section 15 of the Lease without consent of Landlord, and shall be subject to the terms and conditions of said Section 15 with respect to such holdover. Tenant hereby releases Landlord from all claims, costs, causes of action, damages, liabilities or any other matters whatsoever related to the Reduction Space.

Notwithstanding anything contained herein to the contrary, in no event shall Tenant be released from or relieved of any liability with respect to the Reduction Space accruing under the Lease prior to the Reduction Effective Date (including, without limitation, the obligation to perform any conditions and covenants that by the terms of the Lease as it pertains to the Reduction Space survive the termination of the Lease) or of any default under the Lease that occurred prior to the Reduction Effective Date or which would have constituted a default as of the Reduction Effective Date except for the passage of time.

Tenant hereby covenants that Tenant has not at any time done or suffered any act or omission and will not do or suffer any act or omission whereby the Reduction Space or any part thereof are or may be in any way charged, assessed or encumbered. If this covenant is breached, Tenant covenants and agrees to pay Landlord upon demand any and all damages, costs and expenses including, without limitation, attorneys’ fees resulting therefrom.

There shall be no abatement of Rent under or by reason of this Ninth Amendment.

6. Tenant’s Proportionate Share. There shall be no increase in Tenant’s Proportionate Share by reason of the expansion of the Premises hereunder to include the Suite 1730 Expansion Space therein.

7. Condition of Premises. Tenant’s execution and delivery of this Ninth Amendment shall be

conclusive evidence that the Premises and the Suite 1730 Expansion Space were in good order and satisfactory condition as of the date hereof. No agreement of Landlord to alter, remodel, decorate, clean or improve the Premises, the Suite 1730 Expansion Space or the Building and no representation or warranty regarding the condition of the Premises, the Suite 1730 Expansion Space or the Building or regarding any other matter of any kind or nature has been made by or on behalf of Landlord to Tenant under or by reason of this Ninth Amendment and Tenant agrees to accept possession of the Suite 1730 Expansion Space in “as is” condition.

8. Real Estate Broker. Tenant represents that, except for Lincoln Property Company Commercial, Inc. (“Broker”), Tenant has not dealt with any real estate broker, salesperson or finder in connection with this Ninth Amendment and no such person initiated or participated in the negotiation of this Ninth Amendment or is entitled to any fee or commission in connection herewith.

9. Submission. Submission of this Ninth Amendment by Landlord or Landlord’s agent, or their respective agents or representatives, to Tenant for examination and/or execution shall not in any manner bind Landlord and no obligations on Landlord shall arise under this Ninth Amendment unless and until this Ninth Amendment is fully signed and delivered by Landlord and Tenant; provided, however, the execution and delivery by Tenant of this Ninth Amendment to Landlord or Landlord’s agent, or their respective agents or representatives, shall constitute an irrevocable offer by Tenant to extend the lease term of the Lease on the terms and conditions herein contained, which offer may not be revoked for ten (10) days after such delivery.

10. Binding Effect: Conflict. The Lease, as amended hereby, shall continue in full force and effect, subject to the terms and provisions thereof and hereof.

Landlord shall not cause Landlord's Contractor to commence any work necessary to incorporate a Change into the Landlord’s Work until Tenant has approved Landlord’s estimate of the cost of such work and the number of days of Tenant Delay that may result from such work.

3. Performance of Landlord’s Work.

A. After Landlord has approved the Working Plans or any revised Working Plans, Landlord shall promptly solicit bids to perform Landlords Work from three (3) reputable general contractors selected by Landlord and shall provide copies of such bids to Tenant. Landlord agrees to select the low bidder to be Landlord's Contractor unless otherwise requested or approved in writing by Tenant.

A. Landlord shall pay the aggregate cost of Landlord’s Work and the Landlord’s Construction Management Fee up to an amount not to exceed the Tenant Improvement Allowance and Tenant shall pay the excess of the aggregate

cost of Landlord’s Work and the Landlord’s Construction Management Fee over the Tenant Improvement Allowance (the “Excess”) plus the cost of all work other than the Landlord’s Work, if any, which Tenant may elect to do in order to make the Expansion Space ready for Tenant’s occupancy and which has been approved by Landlord pursuant to paragraph 6E below. Tenant shall pay the Excess as provided in Paragraph 4B, and Tenant shall pay the cost of such other work, if any, directly to the persons or entities performing such other work. The “cost of Landlord’s Work” as used in this Workletter shall include all costs incurred by Landlord to plan, design and perform Landlord’s Work as specified by the Tenant Plans and any approved (or deemed approved) revisions thereof (including any Change), including without limitation, the fees and charges of Landlord’s Architect, Landlord’s Engineer and Landlord’s Contractor, all permit and inspection fees and charges, and any costs incurred by or charged to Landlord for (i) unforeseen field conditions, (ii) substitution of materials or finishes due to the unavailability of materials or finishes specified in the Tenant Plans (as revised) that would materially delay substantial completion of Landlord’s Work, (iii) necessary modification of any portions of the Building or its systems to accommodate Landlord’s Work, and (iv) any Change to comply with applicable laws, regulations, codes or ordinances and/or the requirements of any building inspector with jurisdiction over Landlord’s Work.

Tenant shall pay one-half (1/2) of Landlord’s good faith estimate of the Excess billed by Landlord within ten (10) business days after it receives Landlord’s xxxx therefor (the “Initial Excess Payment”). In the event Tenant fails to timely pay any such Initial Excess Payment, Landlord shall be entitled to suspend the performance of Landlord’s Work until such time as such payment is received by Landlord. At such time as the total cost of the Tenant Plans and the Landlord’s Work is finally determined, Landlord shall notify Tenant of such amount in writing. If Tenant has not paid all of the Excess, such notice shall include Landlord’s xxxx to Tenant for the balance of the Excess not previously paid by Tenant, and if Tenant has paid more than the Excess, such notice shall include Landlord’s statement to Tenant showing the amount of the overpayment of the Excess. Tenant shall pay any such balance of the Excess to Landlord within ten (10) business days after the date when Tenant receives such notice and xxxx from Landlord, and Landlord shall pay any such overpayment of the Excess to Tenant within ten (10) business days after the later of the date when Landlord gives such notice and statement to Tenant or the Effective Date. All Landlord’s bills to Tenant for portions of the Excess and Landlord’s notice to Tenant of the finally determined cost of the Tenant Plans and the Landlord’s Work shall itemize the costs in question in reasonable detail.

C. If the aggregate total cost of the Tenant Plans, Landlord's construction Management Fee and the Landlord’s Work is less than the Tenant Improvement Allowance, any unused portion of the Tenant Improvement Allowance shall be retained by Landlord without any claim thereupon accruing to

Tenant.

Landlord shall have the right to enter the Suite 1730 portion of the Existing Premises at all reasonable times without notice and to take all reasonably necessary measures therein to effect the completion of Landlord’s Work therein and such actions by Landlord shall not constitute an actual or constructive eviction of Tenant ₁from the Suite 1730 portion of the Existing Premises, in whole or in part, or entitle Tenant to any claim for set-off, deduction or abatement of Annual Rent or any other charges payable by Tenant under the Lease as amended hereby. Tenant agrees to cooperate with Landlord in facilitating construction of Landlord’s Work in the Suite 1730 portion of the Existing Premises (including without limitation vacating and removing its property from portions of the Suite 1730 portion of the Existing Premises under construction for the duration thereof). Landlord shall use commercially reasonable efforts to minimize the disruption of Tenant’s business during the performance of Landlord’s Work in the Suite 1730 portion of the Existing Premises, it being understood and agreed that performance of Landlord’s Work therein shall necessarily entail the creation of dust, debris, noise, traffic and the partitioning or barricading of areas under construction during Tenant’s business hours.

B. Any such entry prior to the Effective Date shall be under and subject to all of the terms and provisions of this Lease, the same as if the Effective Date had occurred, except that Tenant shall not be obligated to pay any Rent as to the Expansion Space prior to the Effective Date. To the extent not prohibited by law, all entry to the Building or the Expansion Space by Tenant, Tenant’s employees or Tenant’s Contractors prior to the Effective Date shall be solely at the risk of Tenant, Tenant’s employees and Tenant’s Contractors, and Landlord, Landlord’s beneficiaries, the managing agent of the Building and their respective agents, partners and employees shall not be liable in any way for, and Tenant hereby indemnifies, waives and releases them and holds them harmless from any liability for and claims arising from, any injury or death of any person or damage to or theft, robbery, pilferage, loss or loss of the use of any property of Tenant, or any other person or entity or any of Tenant’s work or installations in or about the Expansion Space or the Building which occurs in connection with such entry; provided however, Landlord, the managing agent of the Building and their respective agents, partners and employees shall be liable for, and Tenant does not indemnify, waive or release them or hold them harmless from liability for and claims arising from, their respective negligence or willful misconduct which occurs in connection with such entry and causes any injury to or death of any person or such damage to, theft, pilferage, loss or loss of the use of any such property. The foregoing indemnification, release and waiver of claims shall be in addition to and shall not limit or be limited by any other indemnifications, releases or waivers of claims in this Lease. In addition, and without limiting any other provisions of this Lease, including this Workletter, Tenant shall require all persons and entities performing work on behalf of Tenant to prevent damage to any improvements then existing or under construction in the Expansion Space, in a manner reasonably satisfactory to Landlord, shall allow Landlord and Landlord’s Contractor access to the Expansion Space at all times during the period when Tenant or any person or entity is undertaking work therein and in the event any person or entity performing work on behalf of Tenant, other than the Landlord’s Work, causes any damage to the property of Landlord or others, or to the Landlord’s Work, Tenant shall cause such damage to be repaired at Tenant’s expense, and if Tenant fails to cause such damage to be repaired promptly upon Landlord’s demand therefor, Landlord may, in addition to any other rights or remedies available to Landlord under this Lease or at law or equity, cause such damage to be repaired, in which event Tenant shall promptly upon Landlord’s demand pay to Landlord the cost of such repair.

C. All persons and entities performing work or supplying materials to Tenant shall use only those service corridors and service entrances designated by Landlord for ingress and egress of personnel, and the delivery and removal of equipment and material through or across any common areas of the Building shall only be permitted with the written approval of Landlord, not to be unreasonably withheld, and during hours reasonably determined by Landlord. Landlord shall have the right to order Tenant or any person or entity who violates any of the above requirements which violation is not promptly remedied after oral notice thereof to Tenant, to cease work and, in the case of any person or entity other than Tenant, to remove itself, its equipment and its employees from the Building.

D. Tenant, Tenant’s employees and Tenant's Contractors shall abide by the rules of the site applicable to all contractors and others in or upon the Building or the Expansion Space and shall coordinate and schedule their access to the Expansion Space for labor and materials delivery through the general contractor for the Building and Landlord’s Contractor, or the managing agent for the Building, if so directed by Landlord.

7. Acceptance of Work.

A. Landlord shall give Tenant ten (10) business days’ prior written notice of the expected Turnover Date. On or before the expected Turnover Date, Tenant shall conduct an inspection of the Expansion Space and the Landlord’s Work with Landlord’s representatives and Landlord’s Contractor and develop with such representatives and deliver to Landlord a punch list of all items of the Landlord’s Work which are not complete or which require correction (the “Punch List”). Landlord shall cause Landlord’s Contractor to complete and/or correct all items on the Punch List promptly after Landlord receives the Punch List and shall give Tenant written notice when all of the items on the Punch List have been completed and/or corrected. Any items not on the Punch List which could have, with reasonable diligence, been discovered by Tenant and included on the Punch List shall be deemed accepted by Tenant. If Tenant fails to appear for such inspection or fails to arrange a different date for inspection with Landlord within five (5) business days after receipt of Landlord’s notice of the expected Turnover Date, Tenant shall be deemed to have agreed that no items exist that are incomplete or require correction and therefore Landlord’s Work has been completed and Landlord shall not be required to complete or correct any such items which may in fact exist; or at Landlord’s election, Landlord or Landlord’s Construction Manager may prepare and approve the Punch List on Tenant’s behalf.

B. Landlord and Tenant agree to cooperate with each other in scheduling the inspections of the Expansion Space and the Landlord’s Work described in this Paragraph 7, to make their respective personnel and representatives available on reasonable notice to attend such inspections and develop the Punch List within the inspection time described in this Paragraph 7 and to act reasonably in determining whether or not an item of the Landlord’s Work should be included in the Punch List.

C. At any time after the Turnover Date, Landlord, Landlord’s Contractor, their agents, employees or contractors may enter the Expansion Space to complete and correct Punch List items and such entry for such purpose shall not constitute an actual or constructive eviction of Tenant, in whole or in part, or entitle Tenant to any abatement or diminution of rent or relieve Tenant from any of its obligations under the lease, or subject to the provisions of Article 11 of the Lease, impose any other liability on Landlord, Landlord’s Contractor, their agents, employees or contractors.

C. The failure by Tenant to pay any monies due Landlord pursuant to this Workletter within the time period herein stated shall be deemed a default in the payment of Rent under the terms of this Lease for which Landlord shall be entitled to exercise all remedies available to Landlord for nonpayment of Rent. All late payments shall bear interest pursuant to Article 3.3 of the Lease.

D. This Workletter is expressly made a part of the Lease as amended by this Twelfth Amendment and is subject to each and every term and condition thereof, including, without limitation, the limitations of liability set forth therein.

dispersal of dirt, debris and noise.

H.

Such insurance shall provide for explosion and collapse, completed operations coverage and broad form blanket contractual liability coverage and shall insure Tenant’s Contractors against any and all claims for bodily injury, including death resulting therefrom, and damage to the property of others and arising from its operations under the contracts whether such operations are performed by Tenant’s Contractors or by anyone directly or indirectly employed by any of them.

All policies (except Tenant’s Worker’s compensation policy) shall be endorsed to include as additional insured parties the parties listed on, or required by, the Lease to be named as additional insureds, Landlord and Landlords’ managing agent, Lincoln Property Company Commercial, Inc., and their respective members, partners, directors, officers, employees and agents, and such additional persons as Landlord may designate to Tenant in writing. The waiver of subrogation provisions contained in the Lease shall apply to all insurance policies (except Tenant’s Workmen’s compensation policy) to be obtained by Tenant pursuant to this paragraph. The insurance policy endorsements shall also provide that all additional insured parties shall be given thirty (30) days’ prior written notice of any reductions cancellation or non-renewal of coverage (except that ten (10) days’ notice shall be sufficient in the case of cancellation for non-payment of premium) and shall

provide that the insurance coverage afforded to the additional insured parties thereunder shall be primary to any insurance carried independently by said additional-insured parties. Additionally, where applicable, each policy shall contain a cross-liability and severability of interest clause.

B. Without limitation of the indemnification provisions contained in the Lease, to the fullest extent permitted by law, Tenant agrees to indemnify, protect, defend and hold harmless Landlord, the parties listed, or required by, the Lease to be named as additional insureds, and their respective members, partners, directors, officers, employees, contractors and agents, from and against all claims, liabilities, losses, damages and expenses of whatever nature arising out of or in connection with Tenant’s Work or the entry of Tenant or Tenant’s Contractors into the Building and the Suite LL2-34 Expansion Space, including, without limitation, mechanic’s liens, the cost of any repairs to the Suite LL2-34 Expansion Space or Building necessitated by activities of Tenant or Tenant’s Contractors, bodily injury to persons (including, to the maximum extent provided by law, claims arising under the Illinois Structural Work Act) or damage to the property of Tenant, its employees, agents, invitees, licensees or others, except to the extent caused by the negligence or willful misconduct of Landlord, its agents, employees or contractors. It is understood and agreed that the foregoing indemnity shall be in addition to the insurance requirements set forth above and shall not be in discharge of or in substitution for same or any other indemnity or insurance provision of the Lease but shall be subject to the terms of Section 13 of the original Lease.

5. Cost of Tenant’s Work; Final Documentation.

6. Option to Extend - LL2 Existing Premises.

(a) Provided the Lease as amended hereby is in full force and effect and that no Event of Default by Tenant, as defined in the Lease as amended hereby is in existence either on the date of Tenant’s LL2 Optional Extension Notice (as hereinafter defined) or, unless waived in writing by Landlord for the purpose of this LL2 Extension Option (as hereinafter defined), on the LL2 Optional Extension Effective Date, and provided further that the Lease as amended hereby shall not have theretofore been assigned (other than pursuant to an assignment not requiring Landlord’s consent thereto), Tenant shall have the right, at Tenant’s option, to extend the Term of the Lease as amended hereby with respect to the LL2 Existing Premises for one (1) additional period of five (5) years (the “LL2 Optional Extended Term”) commencing on the day following the LL2 Extension Term Expiration Date (the “LL2 Optional Extension Effective Date”) and ending on the fifth (5^th) anniversary of the LL2 Extension Term Expiration Date. Such option to extend (the “LL2 Extension Option”) shall be exercised by Tenant giving written notice (“Tenant’s LL2 Optional Extension Notice”) of the exercise thereof to Landlord at least eighteen (18) but not more than twenty-one (21) months before the LL2 Extension Term Expiration Date. If Tenant shall fail to timely give Tenant’s LL2 Optional Extension Notice as provided herein, the LL2 Extension Option shall be deemed automatically and irrevocably waived by Tenant. The Term with respect to the LL2 Existing Premises as extended pursuant to the LL2 Extension Option shall be upon the same terms, covenants, and conditions as set forth in the Lease as amended hereby with respect to the LL2 Existing Premises except that the Base Rent payable with respect to the LL2 Existing Premises during the LL2 Optional Extended Term, if exercised, shall equal the Market Rate (as defined below). In the event Tenant exercises the LL2 Extension Option as provided herein, then Tenant shall, within fifteen (15) days after Landlord’s request, execute and deliver an amendment to the Lease memorializing such exercise and the Rent payable by Tenant with respect to the LL2 Existing Premises during the LL2 Optional Extended Term.

(b) For purposes of the LL2 Extension option “Market Rate” shall mean the

rate then being accepted by landlords for comparable improved space in the Development and in office buildings comparable thereto in the West Loop submarket of the downtown Chicago office market on an “as is” renewal basis for a comparable term, taking into account the use, location and floor level within the applicable building, and any other relevant term or condition in making such evaluation, including any tenant improvement allowances or other leasing concessions offered in connection therewith, all as reasonably determined by Landlord and provided to Tenant in writing within thirty (30) days after the date of delivery of Tenant’s LL2 Optional Extension Notice to Landlord (“Landlord’s Market Rate Notice”).

(c) If Tenant disputes Landlord’s determination of the Market Rate, then Tenant shall notify Landlord in writing within fifteen (15) days after the date of delivery of Landlord’s Market Rate Notice to Landlord that Tenant objects to Landlord’s determination and in such notice Tenant shall state its determination of the Market Rate. Landlord and Tenant shall, during the fifteen (15) day period after Tenant’s notice to Landlord of such objection, attempt in good faith to agree on the Market Rate. If Landlord and Tenant are unable to agree, Tenant shall either (i) accept Landlord’s determination of Market Rate or (ii) submit the determination to binding arbitration as provided herein. If Tenant fails to so notify Landlord of Tenant’s election under the preceding sentence within said fifteen (15) day period, Tenant shall be deemed to have accepted Landlord’s determination. If Tenant elects to submit the determination of the Market Rate to arbitration, Landlord and Tenant shall each select an arbitrator within fifteen (15) days after Tenant’s election to arbitrate. If either Landlord or Tenant fail to timely appoint an arbitrator, the arbitrator selected shall select the second (2^nd) arbitrator, who shall be impartial, within fifteen (15) days after such party’s failure to appoint. Each arbitrator must be a licensed real estate broker and have at least ten (10) years experience in the downtown Chicago, Illinois market in the leasing of properties which are similar in character to the Building. The two arbitrators shall, within twenty (20) days of their appointment, select from the two determinations submitted by Landlord and Tenant the one that is closer to the Market Rate as determined by the arbitrators, and said selection shall thereafter be deemed the Market Rate. If the two arbitrators so appointed fail to agree as to which of the determinations submitted by Landlord and Tenant is the closest to the actual Market Rate, the two arbitrators shall appoint a third arbitrator within twenty (20) days after the failure of the initial arbitrators to agree on a Market Rate, to decide upon which of the two determinations submitted is the closest to the actual Market Rate. The arbitrators shall not be permitted to choose as the Market Rate any determination other than the determination presented by either Landlord or Tenant. The fees and expenses of any arbitration shall be borne by the losing party. The arbitrators’ determination shall be final and binding on the parties. If the Market Rate has not been determined by the LL2 Optional Extension Effective Date, Tenant shall pay the Market Rate as determined by Landlord until such time as the arbitrators are able to determine the Market Rate. Upon such determination, Rent for the Premises shall be retroactively adjusted to the LL2 Optional Extension Effective Date. If such

adjustment results in an underpayment of Rent by Tenant, Tenant shall pay Landlord the amount of such underpayment within twenty (20) days after the determination thereof. If such adjustment results in an overpayment of Rent by Tenant, Landlord shall credit such overpayment against the next installment of Rent due under the Lease and, to the extent necessary, any subsequent installments until the entire amount of such overpayment has been credited against Rent.

7. Consent to Assignment and/or Sublease to Certain Affiliates of Tenant. Landlord acknowledges that Tenant may elect, from time to time, to sublease, and/or assign the Lease as amended hereby, as to all or portions of the Premises to Terra Nova Trading, L.L.C. and/or Archipelago Holdings, L.L.C., each of which is an affiliate of the principals of Tenant, or their respective subsidiaries or affiliates (collectively, a “Permitted Transfer”), provided that at least fifteen (15) days prior to the effective date of any such proposed assignment, Tenant shall permit Landlord or its designated agents to examine the current financial statements of Tenant and the proposed assignee for Landlord’s approval (which shall not be withheld provided such financial statements show that the proposed assignee or subtenant is of at least equivalent financial condition (i.e., tangible net worth and current net income) as Tenant as determined by Landlord in its reasonable business judgment) and that the proposed assignment or sublease otherwise complies with the provisions of Article 10 of the Lease which are not inconsistent with the foregoing provisions of this Section. Except for a Permitted Transfer, all other assignments, sublettings, transfers, etc. with respect to the Lease as amended hereby and the Premises which are or would be covered by the provisions of Article 10 of the Lease as amended hereby, shall remain subject to the provisions thereof.

8. Real Estate Broker. Tenant and Tenant each represents that, except for Lincoln Property Company Commercial, Inc. (“Broker”), it has not dealt with any real estate broker, salesperson or finder in connection with this Amendment and no such person initiated or participated in the negotiation of this Amendment or is entitled to any fee or commission in connection herewith. Tenant and Tenant each hereby agrees to indemnify and hold Landlord, its property manager and their respective agents and employees harmless from and against any and all damages, liabilities, claims, actions, costs and expenses (including attorneys’ fees) arising from either (i) any claims or demands of any broker, other than Broker, salesperson or finder for any fee or commission alleged to be due such broker, salesperson or finder in connection with this Amendment or (ii) a claim of, or right to, any lien under the Statutes of the State of Illinois relating to real estate broker liens with respect to any such broker, salesperson or finder retained by the indemnifying party.

9. Submission. Submission of this Amendment by Landlord or Landlord’s agent, or their respective agents or representatives, to Tenant for examination and/or execution shall not in any manner bind Landlord and no obligations on Landlord shall arise under this Amendment unless and until this Amendment is fully signed and delivered by Landlord and Tenant; provided, however, the execution and delivery by Tenant of this Amendment to Landlord or Landlord’s agent, or their respective agents or representatives, shall constitute an irrevocable offer by Tenant to amend the Lease on the terms and conditions herein contained, which offer may not be revoked for ten (10) days

after such delivery.

10. Binding Effect; Conflict. The Lease as amended hereby shall continue in full force and effect, subject to the terms and provisions thereof and hereof. In the event of any conflict between the terms of the Lease and the terms of this Amendment, the terms of this Amendment shall control. This Amendment shall be binding upon and inure to the benefit of Landlord, Tenant and their respective successors and permitted assigns.

11. Limitation of Liability. Neither Landlord nor any officer, director, member or employee of Landlord nor any owner of the Building, whether disclosed or undisclosed, shall have any personal liability with respect to any of the provisions of the Lease, as hereby amended, or the Premises, and if Landlord is in breach or default with respect to Landlord’s obligations under the Lease, as hereby partially assigned and amended, and the Lease, as amended hereby, or otherwise, Tenant shall look solely to the equity interest of Landlord in the Building for the satisfaction of their respective remedies or judgments.

12. Archipelago Lease Contingency. Notwithstanding anything to the contrary contained herein, Landlord and Tenant agree that the effectiveness of this Amendment is contingent upon Landlord and Archipelago entering into the Archipelago Lease (as defined in the 19t Amendment). In the event Landlord and Archipelago fail to enter into the Archipelago Lease within thirty (30) days after the date of this Amendment, then at either Landlord’s or Tenant’s option exercised by written notice to the other, this Amendment shall be null and void and of no further force and effect, and the Lease shall continue in full force and effect as if this Amendment and the 19th Amendment had not been entered into.

IN WITNESS WHEREOF, this Amendment is executed as of the day and year aforesaid.

WITNESSETH:

WHEREAS, Owner or Owner’s predecessor in interest and Licensee have entered into that certain lease dated June 3, 1996, as amended (the “Lease”), of certain premises (the “Premises”) in the building commonly known as 000 Xxxxx Xxxxxx Xxxxx, Xxxxxxx, Xxxxxxxx 00000 (the “Building”);

WHEREAS, Owner intends to install, in the locations shown on Attachment 1 hereto, four (4) emergency generators (the “Generators”) and related equipment (the “Related Equipment”) described on Attachment 2 hereto (which Related Equipment shall be deemed to include the Connecting Equipment, as hereinafter defined, unless otherwise indicted), provided Licensee contributes to the cost of and performs certain portions of such installation as provided herein; and.

WHEREAS, in connection with the Lease, Licensee desires a license to access and use certain space identified on Attachment 1 attached hereto (the “Licensed Space”) for the purpose of repairing, replacing, maintaining, testing and operating three (3) of the Generators (“Licensee’s Generators”) and their related equipment (“Licensee’s Related Equipment”) described as Licensee’s in Attachment 2 attached hereto.

1. GRANT AND TERM OF LICENSE. Owner, subject to and in consideration of the covenants and agreements made by Licensee herein contained, does hereby grant unto the Licensee, for a term commencing on the date of substantial completion of the installation of the Generators and Related Equipment and coterminous with the term of the Lease (as the same may be extended or renewed), unless sooner terminated as provided herein, a license to access and utilize the Licensed Space for the purpose of repairing, replacing, maintaining, testing and operating Licensee’s Generators and Licensee’s Related Equipment in order to obtain emergency standby or back-up power only to the Premises (or portions thereof) and any supplemental HVAC units serving same.

2. INSTALLATION OF THE GENERATORS AND RELATED EQUIPMENT.

(a) The Generators and Related Equipment (other than the Connecting Equipment, as hereinafter defined) shall be installed by Owner or its designated contractors (“Owner’s Contractors”) in accordance with the plans and specifications therefor attached hereto as Attachment 2 (“the “Plans”). Such installation is hereinafter referred to as “Owner’s Work”. Following full execution of this Agreement, Owner shall promptly solicit. bids to perform Owner’s Work from at least two (2) reputable general contractors selected by Owner

and shall provide copies of such bids to Licensee. Owner agrees to select the low bidder to be Owner’s Contractor unless otherwise requested or approved in writing by Licensee. Promptly after Owner’s Contractor is selected, Owner shall cause the Owner’s Contractor to perform Owner’s Work covered by the Plans.

(b) Following substantial completion of Owner’s Work, Licensee or its designated contractors (as pre-approved by Owner) (“Licensee’s Contractors”) shall install the Connecting Equipment (as hereinafter defined) in accordance with the Plans (“Licensee’s Work”). Licensee, Licensee’s employees and Licensee’s Contractors shall perform Licensee’s Work in harmony and without interfering with or delaying Owner or Owner’s Contractor in doing the Owner’s Work or with Owner or any person or entity doing work in the Building, whether for Owner or another tenant or occupant of the Building. All persons and entities performing work or supplying materials to Licensee shall use only those service corridors and service entrances designated by Owner for ingress and egress of personnel, and the delivery and removal of equipment and material through or across any common areas of the Building shall only be permitted with the prior approval of Owner, not to be unreasonably withheld, and during hours reasonably determined by Owner. Owner shall have the right to order Licensee, any of Licensee’s Contractors or any of their respective agents, employees or contractors who violates the above requirements or interferes with the use, occupancy and/or quiet enjoyment of other tenants of the Building to cease work until such time as such violation or interference is remedied. Within thirty (30) days after substantial completion of Licensee’s Work by or on behalf of Licensee, Licensee shall furnish to Owner “as built” drawings of Licensee’s Work. Licensee’s Work shall be performed in accordance with Owner’s standard construction rules and regulations for the Building.

(c) Each of Owner and Licensee shall cause its respective Work, to be done in a first class workerlike manner using only grades of materials equal to or better than those specified by the Plans and in compliance with all governmental laws, ordinances, codes, rules and regulations applicable at the time of the performance thereof.

(d) Each of Owner and Licensee acknowledge that they have reviewed and approved the Plans and that the specifications for Licensee’s Generators and Licensee’s Related Equipment meet their respective requirements.

Any portion of the cost of Owner’s Work which is not particularly specified in the Budget shall be allocated to one of the categories thereof by Owner in its reasonable discretion. The “cost of Owner’s Work” as used in this Agreement shall include all third-party costs incurred by Owner to plan, design and perform Owner’s Work as specified by the Plans and any approved revisions thereof, including without limitation, the fees and charges of Owner’s architect, Owner’s engineer and Owner’s Contractor, all permit and inspection fees and charges, and any costs incurred by or charged to Owner for (i) unforseen field conditions, (ii) substitution of materials or finishes due to the unavailability of materials or finishes specified in the Plans (as revised) that would materially delay substantial completion of Owner’s Work, (iii) necessary modification of any portions of the Building or its systems to accommodate Owner’s Work, and (iv) any change to comply with applicable laws, regulations, codes or ordinances and/or the requirements of any building inspector with jurisdiction over Owner’s Work, plus a project administration fee payable to Owner in the amount of seven percent (7%) of all other costs of Owner’s Work. Owner shall advise Licensee from time to time in the event Owner reasonably estimates that the aggregate amount payable by Licensee as its share of the cost of Owner’s Work shall exceed the aggregate amount of such cost projected to be payable by Licensee by the Budget.

(b) Licensee shall reimburse Owner for Licensee’s share of the cost of Owner’s Work incurred by Owner from time to time during the performance thereof within ten (10) days after Licensee’s receipt from Owner or its managing agent of a reasonably detailed invoice and payout schedule therefor (which payout schedule shall show payment dates, amounts yet to be paid, parties to be paid and the nature of the work to be performed or materials to be supplied by such party), together with reasonable documentation supporting the costs covered thereby which shall include copies of paid invoices, contractor’s affidavit from Owner’s general contractor and lien waivers from all parties shown on such contractor’s affidavit or directly paid by Owner covering the costs subject to reimbursement by Licensee. In the event Licensee fails to timely pay its share of any portion of the cost of Owner’s Work, Owner shall be entitled to suspend the performance of Owner’s Work until such time as such payment is received by Owner. Licensee shall be responsible for 100% of all costs incurred (including cost overruns) for Licensee’s Work and shall timely pay such costs directly to Licensee’s Contractors.

Prior to commencing Licensee’s Work, Licensee shall deliver to Owner certificates of insurance evidencing that such insurance coverage is in effect.

7. LICENSEE’S ACCESS; CONNECTING EQUIPMENT.

(a) Owner hereby grants unto Licensee and Licensee’s Contractors the right, to be exercised as herein set forth, to enter upon the Licensed Space for the sole purpose of gaining access to and repairing, replacing, maintaining, testing and operating Licensee’s Generators and Licensee’s Related Equipment, provided, however, Licensee shall orally notify Owner or its managing agent (or the Building’s on-site security personnel during hours when the Building’s management office is closed) each time Licensee or Licensee’s Contractors requires such access, other than pursuant to an access schedule previously approved by Owner.

Owner further grants to Licensee and Licensee’s Contractors the right of access to the areas where such Connecting Equipment is located for the purposes of maintaining, repairing, replacing, testing, replacing or, to the extent permitted or required hereby, removing the Connecting Equipment, provided, however, Licensee shall orally notify Owner or its managing agent (or the Building’s on-site security personnel during hours when the Building’s management office is closed) Owner each time Licensee or Licensee’s Contractors requires such access, other than pursuant to an access schedule previously approved by Owner.

(b) Anything herein to the contrary notwithstanding, Licensee shall orally notify Owner or its managing agent (or the Building’s on-site security personnel during hours when the Building’s management office is closed) each time Licensee or Licensee’s Contractors desires to enter upon the Licensed Space or other areas outside the Premises where Licensee’s Related Equipment is located, other than pursuant to an access schedule previously approved by Owner, and Licensee and Licensee’s Contractors shall enter upon the Licensed Space and other areas only at such times, in such manner and under such circumstances as shall not (i) cause damage to the Building or any equipment, machinery or facilities located therein or endangerment of life or limb or (ii) interfere with the operation or maintenance of any part of the Building or with any other tenant’s use, occupancy or quiet enjoyment of its premises or the common areas of the Building.

(c) Access to the Licensed Space and other areas of the Building as permitted hereunder shall be provided by Owner or its managing agent (or the Building’s on-site security personnel during hours when the Building’s management office is closed) each time Licensee or Licensee’s Contractors requires such access.

equipment or appurtenance becoming out of repair, or from any occurrence, act, or from the negligence or omission of any tenant or occupant of the Building or of any other person, except to the extent caused by the negligence or wilful misconduct of the released party in the maintenance or operation of the Building.

12. ALTERATIONS. Licensee shall not change, materially alter, replace or remove Licensee’s Generators and Licensee’s Related Equipment without the prior written consent of Owner provided that Owner shall not unreasonably withhold or delay its consent to any changes, alterations or replacements which are required to maintain, test or operate Licensee’s Generators and Licensee’s Related Equipment in proper working order and/or to comply with this Agreement or with applicable laws, codes, ordinances, rules, regulations, orders and directives of any governmental authority with jurisdiction thereover and Owner’s insurer, provided that in no event shall Licensee remove Licensee’s Generators and/or Licensee’s Related Equipment (or any portion thereof) except as part of a permitted replacement thereof.

13. TERMINATION OF AGREEMENT. If the Lease or Licensee’s right to possession of the premises shall be terminated or terminable after the date of this Agreement, because of any default by Licensee under the Lease after the expiration of any applicable cure or grace period, or if Licensee shall default in any of its obligations under this Agreement and such default remains uncured for a period of ten (10) business days after written notice thereof to Licensee (or such longer period as to which Owner shall consent in writing, which consent shall not be unreasonably withheld provided Licensee notifies Owner in writing that it cannot reasonably effect cure within such ten (10) business day period due to causes beyond the reasonable control of Licensee, which notice shall be given to Owner prior to the expiration of such ten (10) business day period and shall contain a description of the causes beyond Licensee’s reasonable control which are delaying such cure and Licensee’s good faith estimate of the additional period of time required for Licensee to effect cure, and further provided that Licensee commences efforts to effect cure within such ten (10) business day period and diligently pursues same to completion), then Owner, at Owner’s sole option, may elect to terminate this Agreement by written notice to Licensee.

14. NOTICES. All notices required to be given hereunder shall be given in accordance with Article 28 of the Lease except as otherwise expressly provided herein.

Notwithstanding anything contained in this Agreement, including, without limitation, Licensee’s contribution toward the cost of the installation thereof as provided herein, ownership of Licensee’s Generators and Licensee’s Related Equipment shall, upon substantial completion of Owner’s Work, vest solely in Licensee, subject to the terms and provisions of this Agreement, and upon Licensee’s request, Owner shall execute and deliver to Licensee bills of sale or such other documentation as Licensee shall reasonably request documenting such ownership by Licensee. In no event shall Licensee mortgage, hypothecate, grant a security interest in or permit a lien of any sort to attach to or be filed against Licensee’s Generators and/or Licensee’s Related Equipment (or any portion thereof), nor shall Tenant sell, convey or transfer all or any part of its ownership interest therein to any party except to an assignee of or subtenant under the Lease pursuant to a Permitted Transfer as defined in the Twelfth Amendment to the Lease.
