(d)    Two Hundred Suites Tenant Improvements. Tenant agrees to submit to
Landlord
within thirty (30) days after the date of this Fifth Amendment, plans and
specifications in such reasonable detail as Landlord may reasonably request
covering Tenant's proposed improvements within the Two Hundred Suites (the
"Tenant's Work"). Tenant shall not commence any work in the Premises until
Landlord has approved such plans and specifications in writing, which approval
shall not be unreasonably withheld or delayed. Landlord agrees to provide such
approval or disapproval within seven (7) business days from receipt of such
plans. If Landlord fails to respond with approval or disapproval within seven
(7) business days from receipt of plans form Tenant, then the Two Hundred Suites
Commencement Date and the Two Hundred Suites Free Rent period shall each be
extended on a day for day basis for every day after seven (7) business days that
Landlord fails to respond to Tenant. In the event of a disapproval of plans,
Landlord agrees to provide detailed reasons for such disapproval so Tenant can
modify the plans to gain approval from Landlord. Such plans, as approved by
Landlord, are herein referred to as the "Plans". It is understood by Landlord
and Tenant that the term "Plans" does not refer to complete architectural and
engineering drawings or full construction drawings, but refers to space design
and concept drawings which will be prepared by Tenant's architect.
Tenant agrees to accept possession of the Two Hundred Suites as of the Two
Hundred Suites Commencement Date provided Landlord makes the space available on
such date as outlined herein, and to proceed with due diligence to perform the
work described in the Plans and to install its fixtures, furniture, and
equipment in the Two Hundred Suites. By occupying the Two Hundred Suites, Tenant
shall be deemed to have acknowledged that the Landlord has complied with all of
its covenants and obligations with respect to the delivery of the Two Hundred
Suites, except for defects or pre-existing conditions in the Two Hundred Suites
that existed prior to Tenant's occupancy or prior to the Two Hundred Suites
Commencement Date. Landlord, at their own cost and expense and in excess of the
Two Hundred Suites Allowance (defined below), agrees to remedy such defect or
pre-existing condition in a timely manner using commercially reasonable efforts.
The Two Hundred Suites Commencement Date and the Two Hundred Suites Free Rent
Period will be extended if there is a delay as a result of such Landlord work.
Subject to the terms and conditions hereinafter set forth, Landlord shall give
Tenant a cash allowance in the amount of One Hundred Eight Thousand One Hundred
Ninety and No/100 Dollars ($108,190.00)(the "Two Hundred Suites Allowance") as
Landlord's contribution to the cost of Tenant's Work within the Two Hundred
Suites, expressly excluding the cost of Tenant's furniture, fixtures (except for
any fixtures that will be attached to the Two Hundred Suites and left by Tenant
upon the expiration or earlier termination of the Lease), equipment and signs.
The Two Hundred Suites Allowance will be paid to Tenant in two (2) installments.
The first installment, equal to one-half (1/2) of the Two Hundred Suites
Allowance, shall be payable to Tenant within seven (7) business days after (i)
one-half (1/2) of the Tenant's Work is complete, (ii) Tenant has submitted
Tenant's written request to Landlord for payment of the first installment of the
Two Hundred Suites Allowance, and (iii) the first one-half (1/2) of the Tenant's
Work has been inspected (as provided below). Tenant's written request for
payment of the first installment of the Two Hundred Suites allowance shall be
accompanied by Tenant's contractor's sworn statement that one-half (1/2) of
Tenant's Work has been completed and paid for in full, shall include partial
lien releases for all Tenant's Work substantiating that all Tenant's Work to
that point has been paid in full. Landlord affirms that Landlord, or Landlord's
representative or architect will be available to inspect the Tenant's Work

--------------------------------------------------------------------------------

no later than three (3) business days after Tenant's submission of the written
request for payment. Landlord further represents that Landlord will not
unreasonably withhold, condition or delay Landlord's approval of Tenant's Work
if it complies with the Plans.
The balance of the Two Hundred Suites Allowance shall be payable to Tenant
within seven (7) business days after (i) completion of the Tenant's Work, (ii)
Tenant's submission of Tenant's written request to Landlord for payment of the
balance of the Two Hundred Suites Allowance, and (iii) the balance of the
Tenant's Work has been inspected (as provided below). Tenant's written request
for payment of the balance of the Two Hundred Suites allowance shall be
accompanied by Tenant's contractor's sworn statement that all of Tenant's Work
has been completed and paid for in full, shall include final lien releases for
all Tenant's Work substantiating that all Tenant's Work has been paid in full,
and shall include a copy of the Certificate of Occupancy obtained by Tenant for
the Two Hundred Suites (if required). Landlord affirms that Landlord, or
Landlord's representative or architect will be available to inspect the Tenant's
Work no later than three (3) business days after Tenant's submission of the
written request for payment. Landlord further represents that Landlord will not
unreasonably withhold, condition or delay Landlord's approval of Tenant's Work
if it complies with the Plans.
Notwithstanding the foregoing, Landlord shall have no obligation to disburse any
portion of the Two Hundred Suites Allowance to Tenant during any period when
Tenant is in default under the Lease. If Tenant cures such default to the
satisfaction of the Landlord during any applicable notice and cure period under
the Lease, the Two Hundred Suites Allowance shall be due and payable to Tenant.
Additionally, in the event Tenant defaults in any of its obligations set forth
in the Lease at any time during the Term beyond any applicable notice and cure
period, in addition to any other rights or remedies Landlord may have as a
result of any such default, the entire amount of the Two Hundred Suites
Allowance hereinabove referenced shall become immediately due and payable by
Tenant to Landlord.
Landlord agrees that Tenant shall have the right to select its own general
contractor for the work within the Two Hundred Suites, with Landlord reasonable
approval, such approval not to be unreasonably withheld or delayed beyond seven
(7) business days. Landlord agrees to use commercially reasonable efforts to
work with and accommodate Tenant's vendors including, but not limited to,
designers, general contractors, furniture, phone and IT professionals. Landlord
specifically disclaims any construction management fee that might otherwise be
due to Landlord. All work will be done in a good, workmanlike manner by Tenant's
contractor.
Prior to commencing any work in any portion of Premises (including but not
limited to Tenant's Work within the Two Hundred Suites) for which the total
anticipated cost is equal to or greater than Thirty Thousand Dollars
($30,000.00), Tenant shall provide Landlord with the contact information for
Tenant's registered lien agent along with a copy of the materials provided to
the registered lien agent pursuant to N.C. Gen. Stat. Sections 44A-11.1 and
44A-11.2 (the "44A Notice"). The 44A Notice shall also include the transaction
number for the project as assigned by liensnc.com. Prior to commencing any work,
Tenant shall: (a) comply with the requirements of N.C. Gen. Stat. Section
44A-11.2(d) and 44A-11.2(e) for the posting of the building permit (if any) and
registered lien agent contact information; (b) include the registered lien agent
contact information in any contract for the performance or furnishing of: labor,
professional design or surveying services,

--------------------------------------------------------------------------------

materials, or rental equipment; and (c) shall require all Tenant's contractors
to include in their subcontracts the contact information for the registered lien
agent.
In addition to all other remedies available to Landlord at law, in equity, and
hereunder, Tenant's failure to comply with the requirements of the immediately
preceding paragraph of this Section 1(d) regarding compliance with the 44A
Notice and the prevention of liens being filed in connection with Tenant's Work
shall constitute an immediate default of the Lease and shall entitle Landlord to
undertake any actions Landlord deems necessary to satisfy the requirements of
N.C. Gen. Stat. Sections 44A-11.1 and 44A-11.2 on Tenant's account and at
Tenant's sole cost and expense, which costs and expenses shall include, without
limitation, all attorneys' fees and, court costs, and an administrative fee
equal to fifteen percent (15%) of all expenses and costs incurred by Landlord.
Such costs, expenses and fees shall be payable by Tenant as Additional Rent
hereunder or, at Landlord's discretion, may be set off against any amount due
and owing Tenant hereunder.
Tenant acknowledges that Tenant shall be solely responsible for installation of
any supplemental HVAC within the Two Hundred Suites as desired or needed by
Tenant (not to exceed five [5] tons). In the event that Tenant installs such a
supplemental HVAC unit within the Two Hundred Suites, Tenant's Total Monthly
Rent shall increase at the rate of One Hundred Dollars ($100.00) per ton each
month thereafter. Tenant also acknowledges that Tenant shall be solely
responsible for installation (and upon termination of the Lease the Tenant shall
remove) at Tenant's sole cost and expense, any data and/or voice network wiring
and cabling located within the Two Hundred Suites installed by and belonging to
Tenant, whether such wiring and cabling is located within the Two Hundred Suites
or within chases or other common areas in the building through which such data
and/or voice network wiring and cabling has been installed to serve the Two
Hundred Suites by Tenant, unless the Landlord waives such requirement in
writing.

Termination) attached to this Fifth Amendment and incorporated herein by
