Exhibit D-2 LEASEHOLD IMPROVEMENTS AGREEMENT
(Suite 1320 Expansion Space)

1.Following the delivery of possession of the Suite 1320 Expansion Space to
Lessee, Lessee shall have the right to refurbish the Suite 1320 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
1320 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 1320 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 Fifteen Thousand Seven Hundred Ten
and 00/100 Dollars ($115,710.00) (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 six (6) months after the Suite 1320
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.

5.
In performing construction of Lessee Improvements, Lessee shall, with regard to
the construction of Lessee Improvements, be bound by each and every term of the
Lease Agreement. Without in any way limiting the foregoing provisions of this
Paragraph 5, the following provisions shall be applicable to Lessee's obligation
to construct Lessee Improvements:

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

thereof), commercial general liability and property damage insurance as Lessor

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)

first class quality (other than materials located in the Suite 1320 Expansion
Space on the Effective Date of Lease Amendment # 17). All doors, light fixtures,
ceiling tiles and other improvements in the Suite 1320 Expansion Space having

contractors to promptly remove from the Buildings, by use of their own trash
containers, all rubbish, dirt, debris and flammable waste, as well as all unused
construction materials, equipment, shipping containers and packaging generated
by Lessee Improvements ; neither Lessee nor Lessee's contractors shall be
permitted to deposit any such materials in Lessor's trash containers or
elsewhere in the Buildings storage of construction materials, tools, equipment
and debris shall be confined within the Suite 1320 Expansion Space.

(i)

Improvements or other installations.

(j)

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.

and all warranties under the contract for construction of Lessee Improvements
and any and all warranties applicable to Lessee Improvements at law or in

maintenance of Lessee Improvements.

(I) 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,

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 1320 Expansion Space, except as provided above with

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
