LEASEHOLD IMPROVEMENTS AGREEMENT
(Suite  1300 and Suite 1490)


1.Following the delivery of possession of the Suite  1300 Expansion  Space  and  the  Suite 1490 Expansion Space to Lessee, Lessee shall have the right to refurbish the Suite 1300 Expansion Space and the Suite 1490 Expansion Space to Lessee's specifications (the "Lessee Improvements"), but only in accordance with the provisions of this Leasehold Improvements Agreement. Lessee and its contractors shall not have the right to perform Lessee Improvements in the Suite 1300 Expansion Space and the Suite 1490 Expansion Space unless and until Lessee has written approval by Lessor of (a) the final plans for the Lessee  Improvements,  (b)  the contractors to be retained by Lessee to perform such Lessee Improvements, and (c) the insurance coverage obtained by Lessee and its contractors in connection with  the Lessee  Improvements. Lessee shall be responsible for all elements of the plans for the Lessee Improvements (including, without limitation, compliance with law, functionality of design, the structural integrity of the design, the configuration of the Suite 1300 Expansion Space and the Suite 1490 Expansion Space and the placement of Lessee's furniture, appliances  and  equipment),  and  Lessor's  approval  of such plans shall in no event relieve Lessee of the responsibility therefor. Lessor's approval of the contractors to perform the Lessee Improvements shall not be unreasonably withheld. Lessor's approval of the general contractor to perform the Lessee Improvements shall not be considered to be unreasonably withheld if any such general contractor (i) does not  have  trade  references reasonably acceptable to Lessor, (ii) does not maintain  insurance  as required by Lessor,  (iii)  does not have the ability to be bonded for the work in an amount satisfactory to Lessor, (iv) does not provide current financial statements reasonably acceptable to Lessor, or (v) is not licensed as a contractor in the state and municipality in which the Leased Premises are located. Lessee acknowledges the foregoing is not intended to be an exclusive list of the reasons why Lessor may reasonably withhold its consent to a general contractor.


2.Promptly after obtaining Lessor's approval of the plans for the Lessee Improvements and before commencing construction of the Lessee Improvements, Lessee shall deliver to Lessor a reasonably detailed estimate of the cost of the Lessee Improvements. If the cost of the Lessee Improvements exceeds the Construction Allowance (hereinafter defined), Lessee shall be solely responsible for the difference. Lessee shall pay to Lessor, within ten (10) days after Lessor's written demand, a construction fee equal to five percent (5%) of  the  cost  of  the  Lessee Improvements to compensate Lessor for reviewing the plans for the Lessee Improvements and for costs incurred by Lessor in facilitating completion of the Lessee Improvements. Lessor reserves the right to deduct such fee from the Construction Allowance.


3.Provided Lessee is not in default at the time of any request for payment, Lessor agrees to contribute up One Hundred Nineteen Thousand Eight Hundred Sixty Five and 00/100 Dollars ($119,865.00) (the "Construction Allowance") toward the cost of performing the Lessee Improvements. The Construction Allowance may only be used for hard costs in connection with the Lessee Improvements. The Construction Allowance shall be paid  to  Lessee  or,  at Lessor's option, to the order of the general contractor that performed the Lessee  Improvements,  within thirty (30) days following receipt by Lessor of the following documentation (1) receipted bills covering all labor and materials expended and used in the Lessee Improvements; and (2) full and final waivers of lien. The Construction Allowance shall be disbursed in the amount reflected on the receipted bills meeting the requirements above.  Notwithstanding  anything  herein  to  the contrary, Lessor shall not be obligated to disburse any portion of the Construction  Allowance during the continuance of an uncured default under the Lease, and Lessor's  obligation  to disburse shall only resume when and if such default is cured. In no event shall the Construction Allowance be used for the purchase of equipment, furniture or other items of personal  property  of  Lessee.  In the event Lessee does not submit to Lessor a written request for payment of the entire Construction Allowance (together with all of the documents and certificates required for such payment) within twelve (12) months after the Suite 1300/Suite1490 Commencement Date, any portion of the Construction Allowance not disbursed to Lessee shall accrue to the sole benefit of Lessor, it being understood that Lessee shall not be entitled to any credit, abatement or other concession in connection therewith. In the event of Lessee's default at the time of any request for payment of the Construction Allowance, Lessor may withhold payment until Lessee's cure of the default.


4.Lessee shall be responsible for all applicable state sales or use taxes, if any, payable in connection with the Lessee Improvements and/or Construction Allowance.

Exhibit D-1

	(b)
	Lessee and each of Lessee's contractors shall comply with all rules and regulations for the Buildings.




		
	(c)
	Prior to commencement of construction of Lessee Improvements, Lessee shall submit to Lessor a list setting forth the name of each of Lessee's contractors and the work that will be performed by each such contractor. Any approval by Lessor of any of  Lessee's  contractors  shall not  in any way be construed as or constitute a representation by or warranty of Lessor as to the abilities of the contractor.




		
	(d)
	Lessee  shall  cause  each  of   Lessee's   contractors   to   deliver   Lessor sufficient evidence (which shall  include,  without  limitation,  certificates of insurance naming Lessor  and  Manager  as  additional  insureds)  that such contractor is covered under such workmen's compensation, (or statutorily permitted waiver thereof), commercial general liability and property damage insurance as Lessor may reasonably request for its protection. All such evidence of insurance must be submitted to and approved by Lessor prior to commencement of construction of Lessee Improvements.




		
	(e)
	Prior to the execution of the construction contract for the construction of Lessee Improvements, Lessee shall submit the proposed form thereof to Lessor for Lessor's review and acceptance. Such contract shall, without in any way limiting Lessor's right to approve the form of such contract, (i) require the contractor to waive all contractual, statutory and constitutional liens against the Leased Premises, the Buildings and the Property as a condition to receipt of any payments thereunder, (ii) require the contractor to conform to the Building Rules and Agreed Regulations and any Building rules applicable to contractors performing work in the Buildings, (iii) require the contractor to  deliver  the  certificates  of insurance (and such other evidence of insurance as is required by Lessor) referred to above, (iv) recognize that Lessor is a third party beneficiary with respect to all warranties (implied or expressed) under the contract or otherwise  applicable  to Lessee  Improvements  at law or in equity,  and  as a third party beneficiary, Lessor shall have the absolute right (but not the obligation) to enforce each and every such warranty, (v) require the contractor to complete construction of Lessee Improvements on or prior to the Suite 1300/Suite1490 Commencement Date, and (vi) require the contractor to work in harmony and cooperate with each other contractor performing work in the Suite 1300 Expansion Space and the Suite 1490 Expansion  Space.




		
	(f)
	Prior to commencement of construction of  Lessee  Improvements (including, without limitation, demolition  of  any existing improvements to allow for the construction of Lessee Improvements), the final plans will, if required by applicable laws, be approved by the appropriate governmental agency and all notices required to be given to any governmental agency shall have been given in  a  timely  manner.  In addition to obtaining all required approvals and permits, the final plans for any portion of the Lessee Improvements  which  may  affect the structural integrity of the Buildings, must be stamped by a structural engineer approved by Lessor, and such final plans must contain a certification that such alterations will not adversely affect the structural integrity of the Buildings.




		
	(g)
	All materials used in the construction of Lessee  Improvements  shall  be new and first-class quality (other than materials located in the Suite 1300 Expansion Space and the Suite 1490 Expansion Space  on  the  Effective Date of Lease Amendment #  16).  All  doors,  light fixtures,  ceiling tiles and other improvements in the Suite 1300 Expansion Space and the Suite 1490 Expansion Space having building standard specifications shall comply with such specifications.




		
	(h)
	Lessee shall maintain the Suite  1300  Expansion  Space  and  the  Suite 1490 Expansion Space and the surrounding areas in a clean and orderly condition during construction. Lessee will cause Lessee's

	(i)
	Lessor shall not be liable for any injury, loss or damage to any of Lessee Improvements  or other  installations.




		
	(j)
	Lessee  shall indemnify and hold  harmless  Lessor from and  against  any and all costs, expenses, claims, liabilities  and causes of  action  arising out of or in connection with work performed by or on behalf of Lessee or Lessee's  contractors.




		
	(k)
	Notwithstanding the fact that Lessor shall be a third party beneficiary  of any and all warranties under the contract for construction of Lessee Improvements and any and all warranties applicable to  Lessee Improvements at law or in equity, Lessor shall in no way be responsible for the function and/or maintenance of Lessee Improvements.




		
	(l)
	Lessee's general  contractor  shall  obtain  a  payment  and  performance bond reasonably acceptable  to  Lessor  covering  the  construction  of Lessee Improvements.




6.Lessee accepts the Leased Premises in its "AS-IS" condition and configuration, without representation or warranty by Lessor or anyone acting on Lessor's  behalf,  it  being  agreed that Lessor shall not be required to perform any work or incur any costs in connection with the construction or demolition of any improvements in the Suite 1300 Expansion Space and the Suite 1490 Expansion Space, except as provided above with respect to payment of the Construction Allowance.


7.This Leasehold Improvements Agreement shall not be applicable to any additional space added to the Leased Premises at any time after the Effective Date of Lease Amendment  #16, whether by any options under the Lease Agreement or otherwise, or to any portion of the Leased Premises or any additions to the Leased Premises in  the  event  of  a renewal  or extension  of  the Term, whether by any options under the Lease Agreement or otherwise, unless expressly so provided in the Lease Agreement or any amendment  or supplement  to the Lease  Amendment  # 16. All capitalized terms used in this Leasehold Improvements Agreement but not defined herein shall have the same meanings ascribed to such terms in the Lease Agreement.
