EXHIBIT B
WORKLETTER
This Exhibit is attached to and made a part of the Amendment by and between TX- NORTHBOROUGH TOWER LIMITED PARTNERSHIP, an Illinois limited partnership (“Landlord”), and NOBLE ENERGY, INC., a Delaware corporation (“Tenant”) for space in the Building located at 100 Glenborough Drive, City of Houston, County of Harris, State of Texas, commonly known as Northborough Tower (the “Building”).
As used in this Work Letter, the “Premises” shall be deemed to mean the Original Premises and the Expansion Space, as defined in the attached Amendment.
		
	I.
	Alterations.

		
	A.
	Tenant, following the delivery of the Expansion Space by Landlord and the full and final execution and delivery of the Amendment to which this Exhibit is attached shall have the right to perform alterations and improvements in the Premises (the “Initial Alterations”).  Notwithstanding the foregoing, Tenant and its contractors shall not have the right to perform Initial Alterations in any portion of the Premises unless and until Tenant has complied with all of the terms and conditions of Article IX of the Lease (with the exception of the construction management fee paid to Landlord which Landlord agrees to waive unless such service is provided as described below in paragraph B), including, without limitation, approval by Landlord of the final plans for the Initial Alterations and the contractors to be retained by Tenant to perform such Initial Alterations.  Tenant shall be responsible for all elements of the design of Tenant’s plans (including, without limitation, compliance with law, functionality of design, the structural integrity of the design, the configuration of the premises and the placement of Tenant’s furniture, appliances and equipment), and Landlord’s approval of Tenant’s plans shall in no event relieve Tenant of the responsibility for such design.  If Landlord fails to approve, disapprove or request modifications to Tenant’s final plans for the Initial Alterations or any modifications thereto within 5 business days after Landlord’s receipt of all information needed by Landlord to properly review Such plans or modifications, then such plans or modifications, as applicable, shall be deemed approved by Landlord.  Landlord’s approval of the contractors to perform the Initial Alterations shall not be unreasonably withheld.  Landlord hereby approves of the following contractors:  Spaw-Maxwell, Cadence McCone, Constructors and Harvey Construction.  So long as Tenant uses one of the aforementioned contractors, Landlord will not require that Tenant or the selected contractor obtain a payment and performance bond for the Initial Alterations.  The parties agree that Landlord’s approval of a contractor not mentioned above to perform the Initial Alterations shall not be considered to be unreasonably withheld if any such general contractor (i) does not have trade references reasonably acceptable to Landlord, (ii) does not maintain insurance as required pursuant to the terms of this Lease, (iii) does not have the ability to be bonded for the work in an amount of no less than 150% of the total estimated cost of the Initial Alterations, (iv) does not provide current financial statements reasonably acceptable to Landlord, or (v) is not licensed as a contractor in the state/municipality in which the Premises is located.  Tenant acknowledges the foregoing is not intended to be an exclusive list of the reasons why Landlord may reasonably withhold its consent to a general contractor.

		
	B.
	At Tenant’s request, Landlord will provide construction management services for a fee of 5% of the Initial Alterations performed.  In such an event, the Landlord shall enter into a direct contract for the Initial Alterations with a general contractor selected by Landlord.  In addition, Landlord shall have the right to select and/or approve of any subcontractors used in connection with the Initial Alterations.

		
	C.
	Tenant agrees to accept the Premises in its “as-is” condition and configuration, it being agreed that Landlord shall not be required to perform any work or, incur any costs in connection with the construction or demolition of any improvements in the Premises.

		
	D.
	This Exhibit shall not be deemed applicable to any additional space added to the Premises at any time or from time to time, whether by any options under the Lease or otherwise, or to any portion of the original Premises or any additions to the Premises in the event of a renewal or extension of the original Term of the Lease, whether by any options under the Lease or otherwise, unless expressly so provided in the Lease or any amendment or supplement to the Lease.

		
	E.
	Notwithstanding anything contained herein to the contrary, Landlord and Tenant hereby agree that the cost of the work, required for ADA compliance, to the restrooms and elevator lobbies of the full floors leased by Tenant (“ADA Work”) shall be borne equally between the two parties.  Landlord shall enter into a direct contract for the Landlord Work with a general contractor selected by Landlord.  The ADA Work shall be completed in connection with the Initial Alterations.  Landlord and Tenant agree to cooperate with each other in order to enable the ADA Work to be performed in a timely manner and with as little inconvenience to the operation of the Initial Alterations as is reasonably possible.

EXHIBIT A
EXPANSION WORK LETTER
As used in this Work Letter, the “Premises” shall he deemed to mean the pre-existing Premises and the applicable Expansion Space, as defined in the attached Fifth Amendment
		
	A.
	Tenant, following the delivery of the applicable Expansion Space by Landlord, shall have the right to perform alterations and improvements in the Premises (the “Expansion Alterations”).  Notwithstanding the foregoing, Tenant and its  contractors shall not have the right to perform Expansion Alterations in any portion of the Premises unless and until Tenant has complied with all of the terms and conditions of Article IX.C of the Lease (with the exception of the construction management fee paid to Landlord which Landlord agrees to waive unless such, service is provided as described below in paragraph B), including, without limitation, approval by Landlord of the final plans for the applicable Expansion Alterations and the contractors to be retained by Tenant to perform such Expansion Alterations.  Tenant shall be responsible for all elements of the design of Tenant’s plans (including, without limitation, compliance with law, functionality of design, the structural integrity of the design, the configuration of the premises and the placement of Tenant’s furniture, appliances and equipment), and Landlord’s approval of Tenant’s plans shall in no event relieve Tenant of the responsibility for such design or create any liability on Landlord.  If Landlord fails to approve, disapprove or request modifications to Tenant’s final plans for the applicable Expansion Alterations or any modifications thereto within five (5) business days after Landlord’s receipt of all information reasonably needed by Landlord to properly review such plans or modifications, then such plans or modifications, as applicable, shall be deemed approved by Landlord.  Landlord’s approval of the contractors to perform the applicable Expansion Alterations shall not be unreasonably withheld.  In addition to the approved contractors listed in Section 1(A) of the Work Letter attached to the Lease as Exhibit D, Landlord hereby also approves Byrd Construction.  The parties agree that Landlord’s approval of a contractor not mentioned above to perform the Expansion Alterations shall not be considered to be unreasonably withheld if any such general contractor (i) does not have trade references reasonably acceptable to Landlord, (ii) does not maintain insurance as required pursuant to the terms of this Lease, (iii) does not have the ability to be bonded for the work in an amount of no less than one hundred fifty percent (150%) of the total estimated cost of the applicable Expansion Alterations, (iv) does not provide current financial statements reasonably acceptable to Landlord, or (v) is not licensed as a contractor in the state/municipality in which the Premises is located.  Tenant acknowledges the foregoing is not intended to be an exclusive list of the reasons why Landlord may reasonably withhold its consent to a general contractor.

		
	B.
	At Tenant’s request, Landlord will provide construction management services for a fee of 5% of the Expansion Alterations performed.  In such an event, the Landlord shall enter into a direct contract for the applicable Expansion Alterations with a general contractor selected by Landlord.  In addition, Landlord shall have the right to select and/or approve of any subcontractors used in connection with the Expansion Alterations.

		
	C.
	Provided Tenant is not then in Material Default, Landlord agrees to contribute the following sums in reimbursement of the actual out-of-pocket cost of performing the Expansion Alterations (the “Expansion Allowance”):

	
			
	Expansion Space
	Allowance per Rentable Square Foot
	Total Allowance

	Fifth Expansion Space
	$5.00
	$121,240.00

	Sixth Expansion Space
	$5.00
	$10,610.00

	Seventh Expansion Space
	$5.00
	$42,485.00

Except as otherwise provided herein, the Expansion Allowance may only be used for the cost of preparing the initial space plan, design and construction documents and mechanical and electrical plans for the applicable Expansion Alterations and for costs of construction and installation in connection with the applicable Expansion Alterations.  The Expansion Allowance shall be paid to Tenant or, if Landlord is the construction manager to the order of the general contractor that performed the applicable Expansion Alterations, within 30 days following receipt by Landlord of (1) receipted bills covering all labor and materials expended and used in the applicable Expansion Alterations; (2) a sworn contractor’s affidavit from the general contractor and a request to disburse from Tenant containing an approval by Tenant of the work done; (3) full and final waivers of lien; (4) as-built plans of the applicable Expansion Alterations; and (5) the certification of Tenant and its architect that the applicable Expansion Alterations have been installed in a good and workmanlike manner in accordance with the approved plans, and in accordance with applicable laws, codes and ordinances.  The Expansion Allowance shall be disbursed in the amount reflected on the receipted bills meeting the requirements above.  Notwithstanding anything herein to the contrary, Landlord shall not be obligated to disburse any portion of the Expansion Allowance during the continuance of an uncured default under the Lease, and Landlord’s obligation to disburse shall only resume when and if such default is cured.
		
	D.
	In no event shall any Expansion Allowance be used for the purchase of equipment, furniture or other items of personal property of Tenant.  If the cost of the applicable Expansion Alterations is less than the applicable Expansion Allowance, Tenant provided it is not then in default under the Lease, shall be entitled to apply up to $2.50 per rentable square foot of the applicable Expansion Space of such, unused Expansion Allowance (the “Cabling Allowance”) toward the cost of purchasing and installing telephone and computer cabling in the Expansion Space.  All such costs, as evidenced by invoices for same, are referred to herein as the “Cabling Costs”.  Landlord shall disburse the Cabling Allowance, or applicable portion thereof (not to exceed the actual Cabling Costs), to Tenant within thirty (30) days after the later to occur of (i) receipt of paid invoices from Tenant with respect to Tenant’s actual Cabling Costs, and (ii) completion of the applicable Expansion Alterations.  If the applicable Expansion Allowance shall not be sufficient to complete the Expansion Alterations, Tenant shall pay the excess costs, plus any applicable state sales or use tax thereon.  Any portion of the applicable Expansion Allowance which exceeds the cost of the applicable Expansion Alterations or is otherwise remaining after the first anniversary of the applicable Expansion Effective Date, shall accrue to the sole benefit of Landlord, it being agreed that Tenant shall not be entitled to any credit, offset, abatement or payment with respect thereto.

		
	E.
	Tenant agrees to accept the Premises and each Expansion Space in its “AS IS” condition and configuration, it being agreed that Landlord shall not be required to perform any work or, except as provided above with respect to the applicable Expansion Allowance, incur any costs in connection with the construction or demolition of any improvements in the Premises or any Expansion Space.

		
	F.
	This Exhibit shall not be deemed applicable to any additional space added to the Premises at any time or from time to time, whether by any options under the Lease or otherwise, or to any portion of the original Premises or any additions to the Premises in the event of a renewal or extension of the original Term of the Lease, whether by any options under the Lease or otherwise, unless expressly so provided in the Lease or any amendment or supplement to the Lease.
