hereunder by Tenant shall contain a clause that such policy and the coverage evidenced thereby
shall be primary and non-contributing with respect to any policies carried by Landlord, and that
any coverage carried by Landlord shall be excess insurance. All insurance coverage must be on

EXHIBIT E TO FOURTH AMENDMENT 
Work Letter 
1.     Allowance. Landlord, provided Tenant is not in default, agrees to provide Tenant with
an allowance in an amount not to exceed $1,111,854.00 ("Tenant Allowance") ($17.00 x 22,302
RSF (Original Premises) plus $30.00 x 24,424 RSF (Expansion Premises)) to be applied toward
the cost of the Landlord's Work in the Premises. If the Allowance shall not be sufficient to
complete the Landlord Work, Landlord shall provide written notice to Tenant prior to
performing such Landlord Work. If Tenant agrees to the additional costs of Landlord Work by
written notice, Tenant shall pay the Excess Costs, plus any applicable state sales or use tax
thereon. 
2.     Costs. The "Costs" of Landlord's Work are all hard and soft costs related to Landlord's
Work including but not limited to architectural plans, permits, construction costs, and
Landlord's project management fee of 3%. Landlord shall pay the Costs up to the amount of the
Allowance, and Tenant shall pay all Costs in excess of the Allowance ("Excess Costs") that
have been approved by Tenant as provided below. At the time the Cost Statement is delivered,
Tenant will pay the Excess Costs to Landlord. 
If Landlord's estimate and/or the actual cost of construction shall exceed the Tenant Allowance,
Landlord, prior to commencing any construction of the Landlord Work, shall submit to Tenant
a written estimate setting forth the anticipated cost of the Landlord Work, including but not
limited to labor and materials, contractor's fees and permit fees. Within three (3) business days
thereafter, Tenant shall either notify Landlord in writing of its approval of the cost estimate, or
specify its objections (which must be reasonable objections) thereto and any desired changes to
the proposed Landlord Work. If Tenant notifies Landlord of such objections and desired
changes, Tenant shall work with Landlord to reach a mutually acceptable alternative cost
estimate. Changes to the scope suggested by Tenant shall be communicated in such a manner
as to allow Landlord to develop an alternative cost estimate within five (5) business days
("First Iteration"). Landlord shall provide an alternative cost estimate to Tenant for Tenant's
approval and Tenant shall have three (3) business days following receipt of the First Iteration to
approve or disapprove of the First Iteration. Any iterations of alternative cost estimates beyond
the First Iteration shall constitute a Tenant Delay. In the event that the Tenant disapproves of
the First Iteration within such three (3) business day period and during the following five (5)
business day period, Landlord and Tenant cannot agree on a final iteration of the cost estimate,
Landlord may proceed with constructing the Landlord Work in accordance with the First
Iteration and any excess costs shall be deemed to be approved Excess Costs. Notwithstanding
the foregoing, if the cost of Landlord's Work does not exceed the Tenant Allowance by more
than ten (10) percent, Tenant shall be deemed to have approved the Excess Costs.

3.    Landlord's Work. 
3.1    Plans. Landlord and Tenant intend to improve the Premises as generally
described on Exhibit E-1 attached hereto. Landlord shall prepare final plans and
specifications (the "Final Plans") to improve the Premises as set forth below. The
installation of the tenant improvements shown on the Final Plans is herein
referred to as "Landlord's Work." Landlord's Work shall not include voice and
data cabling. Tenant shall approve proposed Final Plans delivered by Landlord if
they are consistent with Exhibit E-1 (except for revisions made to comply with
laws or to address site conditions). Approximately five (5) business days after
approval of the Final Plans, Landlord shall deliver to Tenant a Cost Statement
showing the expected costs of Landlord's Work. 
3.2    Construction. Landlord shall perform Landlord's Work substantially in
accordance with the Final Plans. At Landlord's election, substantial completion
may be demonstrated by a certificate of occupancy or other final inspection
(with or without conditions),  a certificate of substantial completion from
Landlord's architect or certification from Landlord. Landlord's Work shall be
deemed substantially complete on the earlier of (i) the date that Landlord has
substantially completed construction in accordance with the Final Plans, or (ii)
the date that Landlord could have achieved such substantial completion absent
delays attributable to Tenant, including delays related to changes pursuant to
Section 3.3 below, and/or delays in Landlord's Work caused by Tenant. 
3.3    Changes in Plans. Tenant may request reasonable changes in the Final Plans;
provided, however, that (i) no such request shall affect any structural change in
the Premises; (ii) if Landlord approves the request, in Landlord's sole discretion,
Tenant shall pay any additional Costs required to implement such change,
including, without limitation, architecture fees, increase in construction costs and
other charges payable hereunder caused by delay, and Tenant shall pay Landlord
for said Costs within fifteen (15) days after written notice from Landlord; and
(iii) such requests shall constitute an agreement by Tenant to any delay in
substantial completion caused by reviewing, processing and implementing such
change. 
3.4    Inspection and Punchlist. Prior to the date which Landlord anticipates to be the
date of substantial completion, Landlord shall deliver to Tenant written notice of
the expected date of such substantial completion. Prior to the date of substantial
completion, if Tenant desires, representatives of Landlord and Tenant shall make
a joint inspection of the Premises to create an agreed upon list of items yet to be
substantially completed. The items included in such list are herein referred to as
"Punch List Items." Certain of the Punch List Items may be completed by
Landlord prior to substantial completion or following substantial completion and
Landlord shall complete any open Punch List Items with due diligence. If the
parties are unable to agree whether any particular item is to be included as a
Punch List Item or whether the same has been satisfactorily completed, then the

Page 23 of 25

DRAFT 
decision of Landlord's architect shall be binding. Landlord shall continue to have
complete access to the Premises for the purpose of taking any and all steps
related to any then remaining Punch List Items. Landlord's obligation to
complete the Punch List Items shall not alter the date of substantial completion.
The obligation of Landlord to perform Punch List Items work shall be to perform
the same to an industry standard level, not to perfection. Except for the
obligation to perform Punch List Items, Landlord shall have no other or further
obligation with respect to construction of Landlord's Work. 
4.    Alternate Use. If any part of the Tenant Allowance is not used to pay Costs (as
defined above) then Tenant may apply such unused Tenant Allowance (up to a maximum of
$2.00 per RSF) towards the purchase of Tenant FF&E. Notwithstanding any other provision
hereof, no part of the Tenant Allowance will be disbursed at any time that an Event of Default
exists. 
5.    Early Access. Tenant will have access to the Premises during the 14 day period prior
to the Expansion Premises Commencement Date to prepare the same for Tenant's use. All
provisions of this Lease shall apply during such period of early access except the obligation to
pay Base Rent and Operating Expenses with respect to the Expansion Premises. Tenant's
activities shall be conducted so as not to interfere with Landlord's Work. 
6.    Limited Application. 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.
