A. All Tenant Improvements shall be identified after award of the contract.

the usage of the Tenant Improvement Allowance. The Government may use
all or part of the Tenant Improvement Allowance. The Government may
return to the Lessor any unused portion of the Tenant Improvement
Allowance in exchange for an equivalent value of rental abatement to be
effective as of the last acceptance date of completed space at a 0%
amortization rate. For instance, should the Government decide not to
use $5.00 per BOMA Office Area square foot of its Tenant Improvement
Allowance, then the rent shall be abated by an equivalent per diem
dollar value beginning as of the last acceptance date of completed
space and ending on such date that the $5.00 per BOMA Office Area
square foot in value has been returned to the Government via this rent
abatement.

3. If the Government spends more on Tenant Improvements than $40.00 per
BOMA Office Area square foot, the Government reserves the right to: 1)
reduce the scope of the Tenant Improvement requirements such that the
fair and reasonable cost of such requirements is reduced to $40.00 per
BOMA Office Area square foot or less; 2) pay lump sum for the overage
upon completion and acceptance of the improvements; or 3) opt for an
increase in the rent according to the negotiated amortization rate over
the firm term of the lease."

THIS AGREEMENT, made and entered into this date by and between:
MCI WORLDCOM NETWORK SERVICES, INC.
Whose address is:

Hereinafter called the Lessor, and the UNITED STATES OF AMERICA, hereinafter
called the Government:

WHEREAS, the parties hereto desire to amend the above Lease.

NOW THEREFORE, these parties for the considerations hereinafter mentioned
covenant and agree that the said Lease is amended, as follows:

Pursuant to the rights reserved by the Government in SFO Section 7.12(D)(3), the
Government has the right to install, at the Government's expense, crash barriers
around the perimeter of the leased premises. Such crash barriers may be concrete
bollards, planters, retractable gates or other architectural features, which
shall conform as much as practical to the existing building's features and
structures "to avoid an armed camp appearance."

As of March 29, 2003, ▇▇▇▇▇▇ has agreed to permit the installation of temporary
crash barriers (i.e., jersey walls) by the Government around the perimeter of
the leased premises, for a period not to exceed 120 days. Upon the expiration of
this 120 period (on July 27, 2003), the Government must remove the temporary
crash barriers. Installation and removal of the temporary crash barriers will be
at the Government's sole cost and expense. If the Government does not remove the
temporary crash barriers and begin the installation of a permanent crash barrier
solution (subject to the provisions below) on or before July 27, 2003, then for
each day after July 27, 2003 that the temporary crash barriers remain around the
perimeter of the leased premises, the Government shall pay to Lessor a daily
pro-rated penalty of $1.00 per ANSI/BOMA USF, per annum, as additional rent on
the 491,707 ANSI/BOMA USF of space leased at the premises ($1,347.14 per day).
Once the temporary crash barriers have been removed, no further penalty, will be
assessed related to such barriers.

During the 120-day period, the Government shall provide Lessor with plans and
specifications for a permanent crash barrier solution, as described in SFO
Section 7.12 (D)(3), for the Lessor's written approval, which approval shall not
be unreasonably withheld, conditioned or delayed.

ALL OTHER TERMS AND CONDITIONS OF THE LEASE SHALL REMAIN IN FORCE AND EFFECT.

IN WITNESS WHEREOF, the parties subscribed their names as of the above date.

proposed) or to other permanent partitions, or both. Rentable space is
the area for which a tenant is charged rent. It is determined by the
building owner and may vary by city or by building within the same
city. The rentable space may include a share of building support/common
areas such as elevator lobbies, building corridors, and floor service
areas. Floor service areas typically include restrooms, janitor rooms,
telephone closets, electrical closets, and mechanical rooms. The
rentable space generally does not include vertical building
penetrations and their enclosing walls, such as stairs, elevator
shafts, and vertical ducts.

B. Enter in this block a computation of the rentable area to be rented to

throughout the building, or the cost of a service or utility furnished
to the Government space exceeds the cost of the same service or utility
furnished to other rented space, explain on a separate sheet. For
convenience, each major category has been divided into separate items
such as salaries and supplies so that they may be entered when
applicable. However, in the event that your records are not maintained
for each item contained in Section I, 5 through 26, the total for a
major category (A through F) may be entered under the category heading

EXHIBIT B

iii) QUANTITY, QUALITY AND SUITABILITY OF FURNITURE, IF ANY.

Both the East and West Towers are furnished with a combination
of workstations, office and conference room furniture
including chairs and files.

The West Tower furniture is in good to excellent condition.
There is furniture for approximately 951 workstations, 90% of
which are 8' x 8', and 10% 6' x 8' and 8' x 10', and 115
private offices. The breakdown is 89% open workstations and
11% private office furniture. The 3rd and 12th floor systems
furniture is ▇▇▇▇▇ ▇▇▇▇▇▇▇▇ and the office furniture is ▇▇▇▇▇
Reff wood product. The executive offices on the 12th floor
will not be furnished. The remaining floors have Kimball Cetra
wood workstations and office furniture. ▇▇▇▇▇ and ▇▇▇▇▇▇▇ are
leading manufacturers in the commercial office industry. The
▇▇▇▇▇ ▇▇▇▇▇▇▇▇ and ▇▇▇▇ and ▇▇▇▇▇▇▇ ▇▇▇▇▇ are the top of the
line products for each manufacturer.

The ▇▇▇▇▇ ▇▇▇▇▇▇▇▇ workstations have neutral fabric panels and
warm gray metal files and trim pieces and plastic laminate
work surfaces. The workstation configuration is typically a
u-shape work surface with overhead shelving and a personal
storage tower, which includes filing and coat storage. The
workstations are ergonomically designed with corner work
surfaces and above work surface power and data outlets. The
majority of panel heights are 54" H.

The ▇▇▇▇▇ ▇▇▇▇ office furniture is modular in design with a
medium wood stain finish. The desk configuration is u-shape
with a "P-top" front work surface for easy conferencing. There
are overhead storage units and tack board above the work
surface.

The Kimball Cetra workstations are a wood furniture system
with neutral fabric panels, plastic laminate file/storage
units and work surfaces. The panels are detailed with medium
finish wood trim pieces. The workstations are ergonomically
designed with corner work surface and above work surface power
and data outlets. The majority of panel heights are 54" H.

The ▇▇▇▇▇▇▇ office furniture is also modular in design with a
light neutral plastic laminate u-shaped work surface and
files. All storage cabinets and files are lockable.

In the East Tower, the workstation and office furniture on the
renovated floors (2nd, 7, 8, 9, 10, 11, 12} is Kimball Cetra.
This furniture is in good to excellent condition. On these
floors, there is furniture for approximately 887 workstations
(53% are 6'x 8'; 30% are 8'x 8'; 17% are 6'x 6'and 8'x 14')
and 18 offices.

The workstation and office furniture is the Kimball Cetra
similar to the West Tower. The remaining floors have a
combination of older ▇▇▇▇▇▇ ▇▇▇▇▇▇ AO2 and Steelcase.

FIRE PROTECTION & LIFE SAFETY EVALUATION

The results of this survey shall be based on an actual walk-through of the
subject premises and review of available construction documents. All building
systems associated with fire protection and/or life safety shall be evaluated
for conformance to the following codes, standards and/or criteria. Any deviance
from the applicable criteria shall be identified and supported by corrective
recommendation(s).

FUNDAMENTAL CODE REQUIREMENTS ARE AS FOLLOWS:

- The offered building shall be evaluated for compliance with the most
recent edition of The Building Officials & Code Administrators (BOCA)
National Building Code; with the exception that chapter 10 of BOCA
shall be replaced by the entire contents of the most recent edition of
NFPA 101, Life Safety Code. All areas which do not meet the most recent
editions of these criteria shall be identified as to the extent which
they do comply.

AUTOMATIC SPRINKLER REQUIREMENTS ARE AS FOLLOWS:

- Where at least 35,000 square feet, any portion of which is on or above
the 6th floor, is offered to the government for lease, the entire
building must be provided with automatic sprinkler protection or an
equivalent level of safety.

- All floors on which the Government occupies below grade space,
regardless of the amount, must be sprinklered (including garage areas
offered for lease by the Government).

- All hazardous areas, as defined by NFPA 101, Life Safety Code, shall be
protected throughout by automatic sprinklers.

3. 552.270-11 SUCCESSORS BOUND (SEP 1999)

This lease shall bind, and inure to the benefit of, the parties and
their respective heirs, executors, administrators, successors, and
assigns.

4. 552.270-23 - SUBORDINATION, NONDISTURBANCE AND ATTORNMENT (SEP 1999)

(a) Lessor warrants that it holds such title to or other interest in
the premises and other property as is necessary to the
Government's access to the premises and full use and enjoyment
thereof in accordance with the provisions of this lease.
Government agrees, in consideration of the warranties and
conditions set forth in this clause, that this lease is subject
and subordinate to any and all recorded mortgages, deeds of
trust and other liens now or hereafter existing or imposed upon
the premises, and to any renewal, modification or extension
thereof. It is the intention of the parties that this provision
shall be self-operative and that no further instrument shall be
required to effect the present or subsequent subordination of
this lease. Government agrees, however, within twenty (20)
business days next following the Contracting Officer's receipt
of a written demand, to execute such instruments as Lessor may
reasonably request to evidence further the subordination of this
lease to any existing or future mortgage, deed of trust or other
security interest pertaining to the premises, and to any water,
sewer or access easement necessary or desirable to serve the
premises or adjoining property owned in whole or in part by
Lessor if such easement does not interfere with the full
enjoyment of any right granted the Government under this lease.

(b) No such subordination, to either existing or future mortgages,
deeds of trust or other lien or security instrument shall
operate to affect adversely any right of the Government under
this lease so long as the Government is not in default under
this lease. Lessor will include in any future mortgage, deed of
trust or other security instrument to which this lease becomes
subordinate, or in a separate nondisturbance agreement, a
provision to the foregoing effect. Lessor warrants that the
holders of all notes or other obligations secured by existing
mortgages, deeds of trust or other security instruments have
consented to the provisions of this clause, and agrees to
provide true copies of all such consents to the Contracting
Officer promptly upon demand.

(c) In the event of any sale of the premises or any portion thereof
by foreclosure of the lien of any such mortgage, deed of trust
or other security instrument, or the giving of a deed in lieu of
foreclosure, the Government will be deemed to have attorned to
any purchaser, purchasers, transferee or transferees of the
premises or any portion thereof and its or their successors and
assigns, and any such purchasers and transferees will be deemed
to have assumed all obligations of the Lessor under this lease,
so as to establish direct privity of estate and contract between
Government and such purchasers or transferees, with the same
force, effect and relative priority in time and right as if the
lease had initially been entered into between such purchasers or
transferees and the Government; provided, further, that the
Contracting Officer and such purchasers or transferees shall,
with reasonable promptness following any such sale or deed
delivery in lieu of foreclosure, execute all such revisions to
this lease, or other writings, as shall be necessary to document
the foregoing relationship.

(d) None of the foregoing provisions may be deemed or construed to
imply a waiver of the Government's rights as a sovereign.

5. 552.270-24 - STATEMENT OF LEASE (AUG 1999)

(a) The Contracting Officer will, within thirty (30) days next
following the Contracting Officer's receipt of a joint written
request from Lessor and a prospective lender or purchaser of the
building, execute and deliver to Lessor a letter stating that the
same is issued subject to the conditions stated in this clause
and, if such is the case, that (1) the lease is in full force and
effect; (2) the date to which the rent and other charges have
been paid in advance, if any; and (3) whether any notice of
default has been issued.

review of the Contracting Officer's lease file as of the
date of issuance;

(2) That the Government shall not be held liable because of
any defect in or condition of the premises or building;

(3) That the Contracting Officer does not warrant or represent
that the premises or building comply with applicable
Federal, State and local law; and

(4) That the Lessor, and each prospective lender and purchaser
are deemed to have constructive notice of such facts as
would be ascertainable by reasonable prepurchase and
precommitment inspection of the Premises and Building and
by inquiry to appropriate Federal, State and local
Government officials.

6. 552.270-25 - SUBSTITUTION OF TENANT AGENCY (SEP 1999)

The Government may, at any time and from time to time, substitute any
Government agency or agencies for the Government agency or agencies, if
any, named in the lease.

7. 552.270-26 - NO WAIVER (SEP 1999)

No failure by either party to insist upon the strict performance of any
provision of this lease or to exercise any right or remedy consequent
upon a breach thereof, and no acceptance of full or partial rent or
other performance by either party during the continuance of any such
breach shall constitute a waiver of any such breach of such provision.

8. 552.270-27 - INTEGRATED AGREEMENT (SEP 1999)

This Lease, upon execution, contains the entire agreement of the parties
and no prior written or oral agreement, express or implied, shall be
admissible to contradict the provisions of the Lease.

9. 552.270-28 - MUTUALITY OF OBLIGATION (SEP 1999)

The obligations and covenants of the Lessor, and the Government's
obligation to pay rent and other Government obligations and covenants,
arising under or related to this Lease, are interdependent. The
Government may, upon issuance of and delivery to Lessor of a final
decision asserting a claim against ▇▇▇▇▇▇, set off such claim, in whole
or in part, as against any payment or payments then or thereafter due
the Lessor under this lease. No setoff pursuant to this clause shall
constitute a breach by the Government of this lease. Prior to exercising
any right of financial offset, the Government shall use best efforts,
circumstances allowing, to provide Lessor with ten (10) days prior
written notice.

10. 552.270-17 - DELIVERY AND CONDITION (SEP 1999)

(a) Unless the Government elects to have the space occupied in
increments, the space must be delivered ready for occupancy as a
complete unit. The Government reserves the right to determine
when the space is substantially complete.

(b) If the premises do not in every respect comply with the
provisions of this lease the Contracting Officer may, in
accordance with the Failure in Performance clause of this lease,
elect to reduce the rent payments.

11. 552.270-18 - DEFAULT IN DELIVERY - TIME EXTENSIONS (SEP 1999)
(VARIATION)

(a) With respect to ▇▇▇▇▇▇'s obligation to deliver the premises
substantially complete by the delivery date, time is of the
essence. If the Lessor fails to work diligently to ensure its
substantial completion by the delivery date or fails to
substantially complete the work by such date, the Government may
by notice to the Lessor terminate this lease. Such termination is
effective when received by Lessor. The Lessor and the Lessor's
sureties, if any, are jointly and severally liable for any
damages to the Government resulting from such termination, as
provided in this clause. The Government shall be entitled to the
following damages:

(1) The Government's aggregate rent and estimated real estate
tax and operating cost adjustments for the firm term and
all option terms of its replacement lease or leases, in
excess of the aggregate rent and estimated real estate tax
and operating cost adjustments for the term. If the
Government procures replacement premises for a term
(including all option terms) in excess of this term, the
Lessor is not liable for excess Government rent or
adjustments during such excess lease term.

(2) All administrative and other costs the Government incurs
in procuring a replacement lease or leases.

(3) Other, additional relief provided for in this lease, at
law, or in equity.

(b) Damages to which the Government is entitled to under this clause
are due and payable thirty (30) days following the date Lessor
receives notice from the Contracting Officer specifying such
damages.

(c) Delivery by Lessor of less than the minimum ANSI/BOMA Office Area
square footage required by this lease shall in no event be
construed as substantial completion, except as the Contracting
Officer permits.

(d) The Government shall not terminate this lease under this clause
nor charge the Lessor with damages under this clause, if (1) the
delay in substantially completing the work arises from excusable
delays and (2) the Lessor within 10 days from the beginning of
any such delay (unless extended in writing by the Contracting
Officer) provides notice to the Contracting Officer of the causes
of delay. The Contracting Officer shall ascertain the facts and
the extent of delay. If the facts warrant, the Contracting
Officer shall extend the delivery date, to

the extent of such delay at no additional costs to the
Government. A time extension is the sole remedy of the Lessor.

12. 552.270-19 - PROGRESSIVE OCCUPANCY (SEP 1999)

The Government shall have the right to elect to occupy the space in
partial increments prior to the substantial completion of the entire
leased premises, and the Lessor agrees to schedule its work so as to
deliver the space incrementally as elected by the Government. The
Government shall pay rent commencing with the first business day
following substantial completion of the entire leased premise unless the
Government has elected to occupy the leased premises incrementally. In
case of incremental occupancy, the Government shall pay rent pro rata
upon the first business day following substantial completion of each
incremental unit. Rental payments shall become due on the first workday
of the month following the month in which an increment of space is
substantially complete, except that should an increment of space be
substantially completed after the fifteenth day of the month, the
payment due date will be the first workday of the second month following
the month in which it was substantially complete. The commencement date
of the firm lease term will be a composite determined from all rent
commencement dates.

13. 552.270-21 - EFFECT OF ACCEPTANCE AND OCCUPANCY (SEP 1999)

Neither the Government's acceptance of the premises for occupancy, nor
the Government's occupancy thereof, shall be construed as a waiver of
any requirement of or right of the Government under this Lease, or as
otherwise prejudicing the Government with respect to any such
requirement or right.

14. 552.270-6 - MAINTENANCE OF BUILDING AND PREMISES - RIGHT OF ENTRY
(SEP 1999)

Except in case of damage arising out of the willful act or negligence of
a Government employee, Lessor shall maintain the premises, including the
building, building systems, and all equipment, fixtures, and
appurtenances furnished by the lessor under this lease, in good repair
and condition so that they are suitable in appearance and capable of
supplying such heat, air conditioning, light, ventilation, safety
systems, access and other things to the premises, without reasonably
preventable or recurring disruption, as is required for the Government's
access to, occupancy, possession, use and enjoyment of the premises as
provided in this lease. For the purpose of so maintaining the premises,
the Lessor may at reasonable times enter the premises with the approval
of the authorized Government representative in charge.

15. 552.270-10 - FAILURE IN PERFORMANCE (SEP 1999)

The covenant to pay rent and the covenant to provide any service,
utility, maintenance, or repair required under this lease are
interdependent. In the event of any failure by the Lessor to provide any
service, utility, maintenance, repair or replacement required under this
lease the Government may, by contract or otherwise, perform the
requirement and deduct from any payment or payments under this lease,
then or thereafter due, the resulting cost to the Government, including
all administrative costs. If the Government elects to perform any such
requirement, the Government and each of its contractors shall be
entitled to access to any and all areas of the building, access to which
is necessary to perform any such requirement, and the Lessor shall
afford and facilitate such access. Alternatively, the Government may
deduct from any payments under this lease, then or thereafter due, an
amount which reflects the reduced value of the contract requirement not
performed. No deduction from rent pursuant to this clause shall
constitute a default by the Government under this lease. These remedies
are not exclusive and are in addition to any other remedies which may be
available under this lease or at law. The Government will use best
efforts to notify Lessor and allow reasonable time to cure.

16. 552.270-22 - DEFAULT BY ▇▇▇▇▇▇ DURING THE TERM (SEP 1999)

(a) Each of the following shall constitute a default by Lessor under
this lease:

(1) Failure to maintain, repair, operate or service the
premises as and when specified in this lease, or failure
to perform any other requirement of this lease as and when
required provided any such failure shall remain uncured
for a period of thirty (30) days next following Lessor's
receipt of notice thereof from the Contracting Officer or
an authorized representative, unless Lessor is reasonably
pursuing a cure of the failure.

(b) If a default occurs, the Government may, by notice to Lessor,
terminate this lease for default and if so terminated, the
Government shall be entitled to the damages specified in the
Default in Delivery-Time Extensions clause. The Government will
use its best efforts to notify Lessor or management agent and
allow reasonable time to cure.

17. 552.270-7 - FIRE AND CASUALTY DAMAGE (SEP 1999)

If the entire premises are destroyed by fire or other casualty, this
lease will immediately terminate. In case of partial destruction or
damage, so as to render the premises untenantable, as determined by the
Government, the Government may terminate the lease by giving written
notice to the Lessor within 15 calendar days of the fire or other
casualty; if so terminated, no rent will accrue to the Lessor after such
partial destruction or damage; and if not so terminated, the rent will
be reduced proportionately by supplemental agreement hereto effective
from the date of such partial destruction or damage. Nothing in this
lease shall be construed as relieving Lessor from liability for damage
to or destruction of property of the United States of America caused by
the willful or negligent act or omission of Lessor.

18. 552.270-8 - COMPLIANCE WITH APPLICABLE LAW (SEP 1999)

Lessor shall comply with all Federal, state and local laws applicable to
the Lessor as owner or lessor, or both, of the building or premises,
including, without limitation, laws applicable to the construction,
ownership, alteration or operation of both or either thereof, and will
obtain all necessary permits, licenses and similar items at Lessor's
expense. The Government will comply with all Federal state and local
laws applicable to and enforceable against it as a tenant under this
lease; provided that nothing in this lease shall be construed as a
waiver of any sovereign immunity of the Government. This lease shall be
governed by Federal law.

19. 552.270-12 - ALTERATIONS (SEP 1999)

The Government shall have the right during the existence of this lease
to make alterations, attach fixtures, and erect structures or signs in
or upon the premises hereby leased, which fixtures, additions or
structures so placed in, on, upon, or attached to the said premises
shall be and remain the property of the Government and may be removed or
otherwise disposed of by the Government. If the lease contemplates that
the Government is the sole occupant of the building, for purposes of
this clause, the leased premises include the land on which the building
is sited and the building itself. Otherwise, the Government shall have
the right to tie into or make any physical connection with any structure
located on the property as is reasonably necessary for appropriate
utilization of the leased space. All mechanical, electrical, and/or
structural alterations affecting the building systems shall either be

22. 552.232-75 - PROMPT PAYMENT (SEP 1999)

The Government will make payments under the terms and conditions
specified in this clause. Payment shall be considered as being made on
the day a check is dated or an electronic funds transfer is made. All
days referred to in this clause are calendar days, unless otherwise
specified.

(a) Payment due date.

(1) Rental payments. Rent shall be paid monthly in arrears and
will be due on the first workday of each month, and only
as provided for by the lease.

(i) When the date for commencement of rent falls on
the 15th day of the month or earlier, the
initial monthly rental payment under this
contract shall become due on the first workday of
the month following the month in which the
commencement of the rent is effective.

(ii) When the date for commencement of rent falls after
the 15th day of the month, the initial monthly
rental payment under this contract shall become due
on the first workday of the second month following
the month in which the commencement of the rent is
effective.

(2) Other payments. The due date for making payments other
than rent shall be the later of the following two events:

(i) The 30th day after the designated billing office
has received a proper invoice from the Contractor.

(ii) The 30th day after Government acceptance of the
work or service. However, if the designated billing
office fails to annotate the invoice with the
actual date of receipt, the invoice payment due
date shall be deemed to be the 30th day after the
Contractor's invoice is dated, provided a proper
invoice is received and there is no disagreement
over quantity, quality, or Contractor compliance
with contract requirements.

(b) Invoice and inspection requirements for payments other than rent.

(1) The Contractor shall prepare and submit an invoice to the
designated billing office after completion of the work. A
proper invoice shall include the following items:

(i) Name and address of the Contractor.

(ii) Invoice date.

(iii) Lease number.

(iv) Government's order number or other authorization.

(v) Description, price, and quantity of work or
services delivered.

(vi) Name and address of Contractor official to whom
payment is to be sent (must be the same as that in
the remittance address in the lease or the order.)

(vii) Name (where practicable), title, phone number, and
mailing address of person to be notified in the
event of a defective invoice.

(2) The Government will inspect and determine the
acceptability of the work performed or services delivered
within 7 days after the receipt of a proper invoice or
notification of completion of the work or services unless
a different period is specified at the time the order is
placed. If actual acceptance occurs later, for the purpose
of determining the payment due date and calculation of
interest, acceptance will be deemed to occur on the last
day of the 7-day inspection period. If the work or service
is rejected for failure to conform to the technical
requirements of the contract, the 7 days will be counted
beginning with receipt of a new invoice or notification.
In either case, the Contractor is not entitled to any
payment or interest unless actual acceptance by the
Government occurs.

(1) An interest penalty shall be paid automatically by the
Government, without request from the Contractor, if
payment is not made by the due date.

(2) The interest penalty shall be at the rate established by
the Secretary of the Treasury under Section 12 of the
Contract Disputes Act of 1978 (41 U.S.C. 611) that is in
effect on the day after the due date. This rate is
referred to as the "Renegotiation Board Interest Rate,"
and it is published in the Federal Register semiannually
on or about January 1 and July 1. The interest penalty
shall accrue daily on the payment amount approved by the
Government and be compounded in 30-day increments
inclusive from the first day after the due date through
the payment date.

(3) Interest penalties will not continue to accrue after the
filing of a claim for such penalties under the clause at
52.233-1, Disputes, or for more than 1 year. Interest
penalties of less than $1.00 need not be paid.

(4) Interest penalties are not required on payment delays due
to disagreement between the Government and Contractor over
the payment amount or other issues involving contract
compliance or on amounts temporarily withheld or retained
in accordance with the terms of the contract. Claims
involving disputes, and any interest that may be payable,
will be resolved in accordance with the clause at
52.233-1, Disputes.

rent. The rate per USF is determined by dividing the total annual
rental by the Usable square footage set forth in the lease.

USF Not Delivered X Rate per USF = Reduction in Annual Rent.

(a) of this clause that a price or cost reduction should
be made, the Contractor agrees not to raise the following
matters as a defense:

(i) The Contractor or subcontractor was a sole source
supplier or otherwise was in a superior bargaining
position and thus the price of the contract would
not have been modified even if accurate, complete,
and current cost or pricing data had been
submitted.

(ii) The Contracting Officer should have known that the
cost or pricing data in issue were defective even
though the Contractor or subcontractor took no
affirmative action to bring the character of the
data to the attention of the Contracting Officer.

total cost of the contract and there was no
agreement about the cost of each item procured
under the contract.

(iv) The Contractor or subcontractor did not submit a
Certificate of Current Cost or Pricing Data.

(2) (i) Except as prohibited by subdivision (c)(2)(ii)
of this clause, an offset in an amount determined

Officer that, to the best of the
Contractor's knowledge and belief, the
Contractor is entitled to the offset in the
amount requested; and

(B) The Contractor proves that the cost or
pricing data were available before the "as
of" date specified on its Certificate of
Current Cost or Pricing Data, and that the
data were not submitted before such date.

(ii) An offset shall not be allowed if--

(A) The understated data were known by the
Contractor to be understated before the "as
of" date specified on its Certificate of
Current Cost or Pricing Data; or

(B) The Government proves that the facts
demonstrate that the contract price would
not have increased in the amount to be
offset even if the available data had been
submitted before the "as of" date specified
on its Certificate of Current Cost or
Pricing Data.

Regulation (48 CFR 4.7), whichever expires earlier, have access to and

(g) The Contractor shall insert a clause containing all the terms of
this clause, including this paragraph (g), in all subcontracts

type or any combination of these;

(2) For which cost or pricing data are required; or

(3) That require the subcontractor to furnish reports as

(a) This contract is subject to the Contract Disputes act of 1978, as
amended (41 U.S.C. 601-613)

(b) Except as provided in the Act, all disputes arising under or
relating to this contract shall be resolved under this clause.

(c) "Claim," as used in this clause, means a written demand or
written assertion by one of the contracting parties seeking, as
a matter of right, the payment of money in a sum certain, the
adjustment or interpretation of contract terms, or other relief
arising under or relating to this contract. A claim arising
under a contract, unlike a claim relating to that contract, is a
claim that can be resolved under a contract clause that provides
for the relief sought by the claimant. However, a written demand
or written assertion by the Contractor seeking the payment of
money exceeding $100,000 is not a claim under the Act until
certified as required by subparagraph (d)(2) of this clause. A
voucher, invoice, or other routine request for payment that is
not in dispute when submitted is not a claim under the Act. The
submission may be converted to a claim under the Act, by
complying with the submission and certification requirements of
this clause, if it is disputed either as to liability or amount
or is not acted upon in a reasonable time.

(d) (1) A claim by the Contractor shall be made in writing
and, unless otherwise stated in this contract, submitted
within 6 years after accrual of the claim to the
Contracting Officer for a written decision. A claim by the
Government against the Contractor shall be subject to a
written decision by the Contracting Officer.

(2) (i) The Contractor shall provide the certification
specified in paragraph (d)(2)(iii) of this clause
when submitting any claim exceeding $100,000.

(ii) The certification requirement does not apply to
issues in controversy that have not been submitted
as all or part of a claim.

(iii) The certification shall state as follows: "I
certify that the claim is made in good faith; that
the supporting data are accurate and complete to
the best of my knowledge and belief; that the
amount requested accurately reflects the contract
adjustment for which the Contractor believes the
Government is liable; and that I am duly authorized
to certify the claim on behalf of the Contractor."

(3) The certification may be executed by any person duly
authorized to bind the Contractor with respect to the
claim.

(e) For Contractor claims of $100,000 or less, the Contracting
Officer must, if requested in writing by the Contractor, render a
decision within 60 days of the request. For Contractor-certified
claims over $100,000, the Contracting Officer must, within 60
days, decide the claim or notify the Contractor of the date by
which the decision will be made.

(f) The Contracting Officer's decision shall be final unless the
Contractor appeals or files a suit as provided in the Act.

(g) If the claim by the Contractor is submitted to the Contracting
Officer or a claim by the Government is presented to the
Contractor, the parties, by mutual consent, may agree to use
alternative disputes resolution (ADR). If the Contractor refuses
an offer for ADR, the Contractor shall inform the Contracting
Officer, in writing, of the Contractor's specific reasons for
rejecting the offer.

(h) The Government shall pay interest on the amount found due and
unpaid from (1) the date that the Contracting Officer receives
the claim (certified if required); or (2) the date that payment
otherwise would be due, if that date is later, until the date of
payment. With regard to claims having defective certifications,
as defined in FAR 33.201, interest shall be paid from the date
that the Contracting Officer initially receives the claim.
Simple interest on claims shall be paid at the rate, fixed by
the Secretary of the Treasury as provided in the Act, which is
applicable to the period during which the Contracting Officer
receives the claim and then at

contract, pending final resolution of any request for relief,
claim, appeal, or action arising under the contract, and comply
with any decision of the Contracting Officer.

representative of workers with which it has a collective
bargaining agreement or other contract or understanding,
the notice to be provided by the Contracting Officer
advising the labor union or workers' representative of the
Contractor's commitments under this clause, and post

amended, and the rules, regulations, and orders of the

order of the Secretary of Labor, this contract may be
canceled, terminated, or suspended in whole or in part and
the Contractor may be declared ineligible for further
Government contracts, under the procedures authorized in

may be imposed and remedies invoked against the Contractor
as provided in Executive Order 11246, as amended, the

or as otherwise provided by law.

(10) The Contractor shall include the terms and conditions of
subparagraph (b)(1) through (11) of this clause in every
subcontract or purchase order that is not exempted by the
rules, regulations, or orders of the Secretary of Labor
issued under Executive Order 11246, as amended, so that
these terms and conditions will be binding upon each

(a) This clause does not apply to small business concerns.

company or a portion thereof (e.g., division, plant, or product
line).

"Individual contract plan" means a subcontracting plan that
covers the entire contract period (including option periods),

"Master plan" means a subcontracting plan that contains all the
required elements of an individual contract plan, except goals,

"Subcontract," means any agreement means any agreement (other
than one involving an employer-employee relationship) entered
into by a Federal Government prime Contractor or subcontractor
calling for supplies or services required for performance of the
contract or subcontract.

(c) The offeror, upon request by the Contracting Officer, shall
submit and negotiate a subcontracting plan, where applicable,
which separately addresses subcontracting with small business,
veteran-owned small business, HUBZone small business concerns,
small disadvantaged business, and women-owned small business
concerns. If the offeror is submitting an individual contract
plan, the plan must separately address subcontracting with small
business, veteran-owned small business, HUBZone small business,
small disadvantaged business, and women-owned small business
concerns, with a separate part for the basic contract and
separate parts for each option (if any). The plan shall be
included in and made a part of the resultant contract. The
subcontracting plan shall be negotiated within the time
specified by the Contracting Officer. Failure to submit and
negotiate the subcontracting plan shall make the offeror
ineligible for award of a contract.

subcontracting dollars, for the use of small business,
veteran-owned small business, HUBZone small business,

of veteran-owned small business concerns, and offerors may
include them within the subcontracting plan goal for
veteran-owned small business concerns. A

Research and Information Division of the Minority Business
Development Agency in the Department of Commerce, or
small, HUBZone, small disadvantaged, and women-owned small
business trade associations). A firm may rely on the
information contained in PRO-Net as an accurate
representation of a concern's size and ownership
characteristics for the purposes of maintaining a small,
veteran-owned small, HUBZone small, small disadvantaged,
and women-owned small business source list. Use of PRO-Net
as its source list does not relieve a firm of its
responsibilities (e.g., outreach, assistance, counseling,
or publicizing subcontracting opportunities) in this
clause.

(6) A statement as to whether or not the offeror included
indirect costs in establishing subcontracting goals, and
a description of the method used to determine the

business concerns, veteran-owned small business
concerns, service-disabled veteran-owned small
business concerns, small disadvantaged business
concerns, women-owned small business concerns, and

data that identify small business, veteran-owned
small business, HUBZone small business, small

(e) In order to effectively implement this plan to the extent
consistent with efficient contract performance, the Contractor
shall perform the following functions:

(1) Assist small business, veteran-owned small business,
HUBZone small business, small disadvantaged and
women-owned small business concerns by arranging
solicitations, time for the preparation of bids,
quantities, specifications, and delivery schedules so as
to facilitate the participation by such concerns. Where
the Contractor's lists of potential small, veteran-owned
small business, HUBZone small business, small
disadvantaged and women-owned small business
subcontractors are excessively long, reasonable efforts
shall be made to give all such small business concerns an
opportunity to compete over a period of time.

(2) Provide adequate and timely consideration of the
potentialities of small, veteran-owned small business,
HUBZone small business, small disadvantaged and
women-owned small business concerns in all "make-or-buy"
decisions.

(3) Counsel and discuss subcontracting opportunities with
representatives of small, veteran-owned small business,
HUBZone small business, small disadvantaged and
women-owned small business firms.

(4) Provide notice to subcontractors concerning penalties and
remedies for misrepresentations of business status as
small, veteran-owned small business, HUBZone small
business, small disadvantaged or women-owned small
business for the purpose of obtaining a subcontract that
is to be included as part or all of a goal contained in
the Contractor's subcontracting plan.

(f) A master plan on a plant or division-wide basis that contains all
the elements required by paragraph (d) of this clause, except
goals, may be incorporated by reference as a part of the
subcontracting plan required of the offeror by this clause;
provided -

(1) The master plan has been approved;

(2) The offeror ensures that the master plan is updated as
necessary and provides copies of the approved master plan,
including evidence of its approval, to the Contracting
Officer; and

(3) Goals and any deviations from the master plan deemed
necessary by the Contracting Officer to satisfy the
requirements of this contract are set forth in the
individual subcontracting plan.

(g) A commercial plan is the preferred type of subcontracting plan
for contractors furnishing commercial items. The commercial plan
shall relate to the offeror's planned subcontracting generally,
for both commercial and Government business, rather than solely
to the Government contract. Commercial plans are also preferred
for subcontractors that provide commercial items under a prime
contract, whether or not the prime contractor is supplying a
commercial item.

(h) Prior compliance of the offeror with other such subcontracting
plans under previous contracts will be considered by the
Contracting Officer in determining the responsibility of the
offeror for award of the contract.

(i) The failure of the Contractor or subcontractor to comply in good
faith with -

(1) The clause of this contract entitled "Utilization of Small
Business Concerns," or

(2) An approved plan required by this clause, shall be a
material breach of the contract.

(j) The Contractor shall submit the following reports:

(1) Standard Form 294, Subcontracting Report for Individual
Contracts. This report shall be submitted to the
Contracting Officer semiannually and at contract
completion. The report covers subcontract award data
related to this contract. This report is not required for
commercial plans.

(2) Standard Form 295, Summary Subcontract Report. This report
encompasses all the contracts with the awarding agency. It
must be submitted semi-annually for contracts with the
Department of Defense and annually for contracts with
civilian agencies. If the reporting activity is covered by
a commercial plan, the reporting activity must report
annually all subcontract awards under that plan. All
reports submitted at the close of each fiscal year (both
individual and commercial plans) shall include a breakout,
in the Contractor's format, of subcontract awards, in
whole dollars, to small disadvantaged business concerns by
North American Industry Classification System (NAICS)
Industry Subsector. For a commercial plan, the Contractor
may obtain from each of its subcontractors a predominant
NAICS Industry Subsector and report all awards to that
subcontractor under its predominant NAICS Industry
Subsector.

47. 52.219-16 LIQUIDATED DAMAGES - SUBCONTRACTING PLAN (JAN 1999)

(a) Failure to make a good faith effort to comply with the
subcontracting plan, as used in this clause, means a willful or
intentional failure to perform in accordance with the
requirements of the subcontracting plan approved under the clause
in this contract entitled "Small Business Subcontracting Plan,"
or willful or intentional action to frustrate the plan.

(b) Performance shall be measured by applying the percentage goals
to the total actual subcontracting dollars or, if a commercial
plan is involved, to the pro rata share of actual subcontracting
dollars attributable to Government contracts covered by the
commercial plan. If, at contract completion or, in the case of a
commercial plan, at the close of the fiscal year for which the
plan is applicable, the Contractor has failed to meet its
subcontracting goals and the Contracting Officer decides in
accordance with paragraph (c) of this clause that the Contractor
failed to make a good faith effort to comply with its
subcontracting plan, established in accordance with the clause
in this contract entitled "Small Business Subcontracting Plan,"
the Contractor shall pay the Government liquidated damages in an
amount stated. The amount of probable damages attributable to
the Contractor's failure to comply shall be an amount equal to
the actual dollar amount by which the Contractor failed to
achieve each subcontract goal.

(c) Before the Contracting Officer makes a final decision that the
Contractor has failed to make such good faith effort, the
Contracting Officer shall give the Contractor written notice
specifying the failure and permitting the Contractor to
demonstrate what good faith efforts have been made and to
discuss the matter. Failure to respond to the notice may be
taken as an admission that no valid explanation exists. If,
after consideration of all the pertinent data, the Contracting
Officer finds that the Contractor failed to make a good faith
effort to comply with the subcontracting plan, the Contracting
Officer shall issue a final decision to that effect and require
that the Contractor pay the Government liquidated damages as
provided in paragraph (b) of this clause.

(d) With respect to commercial plans, the Contracting Officer who
approved the plan will perform the functions of the Contracting
Officer under this clause on behalf of all agencies with
contracts covered by the commercial plan.

(Acquisition of Leasehold Interests in Real Property)

1. 552.270-1 - INSTRUCTIONS TO OFFERORS - ACQUISITION OF LEASEHOLD INTERESTS
IN REAL PROPERTY (MAR 1998)

(a) Definitions. As used in this provision--

"Discussions" are negotiations that occur after establishment of the
competitive range that may, at the Contracting Officer's discretion, result
in the offeror being allowed to revise its proposal.

"In writing" or "written" means any worded or numbered expression which can
be read, reproduced, and later communicated, and includes electronically
transmitted and stored information.

"Proposal modification" is a change made to a proposal before the
solicitation's closing date and time, or made in response to an amendment,
or made to correct a mistake at any time before award.

"Proposal revision" is a change to a proposal made after the solicitation
closing date, at the request of or as allowed by a Contracting Officer as
the result of negotiations.

"Time," if stated as a number of days, is calculated using calendar days,
unless otherwise specified, and will include Saturdays, Sundays, and legal
holidays. However, if the last day falls on a Saturday, Sunday, or legal
holiday, then the period shall include the next working day.

(b) Amendments to solicitations. If this solicitation is amended, all
terms and conditions that are not amended remain unchanged. Offerors
shall acknowledge receipt of any amendment to this solicitation by the
date and time specified in the amendment(s).

(1) Unless other methods (e.g., electronic commerce or facsimile) are
permitted in the solicitation, proposals and modifications to
proposals shall be submitted in paper media in sealed envelopes
or packages. Offers must be:

(i) Submitted on the forms prescribed and furnished by the
Government as a part of this solicitation or on copies of
those forms, and

(ii) Signed. The person signing an offer must initial each
erasure or change appearing on any offer form. If the
offeror is a partnership, the names of the partners
composing the firm must be included with the offer.

(2) Late proposals and revisions.

(i) The Government will not consider any proposal received at
the office designated in the solicitation after the exact
time specified for receipt of offers unless it is received
before the Government makes award and it meets at least one
of the following conditions:

(A) It was sent by registered or certified mail not later
than the 5th calendar day before the date specified for
receipt of offers (e.g., an offer submitted in response
to a solicitation requiring receipt of offers by the
20th of the month must have been mailed by the 15th).

(B) It was sent by mail (or telegram or facsimile, if
authorized) or hand-carried (including delivery by a
commercial carrier) if it is determined by the
Government that the late receipt was due primarily to
Government mishandling after receipt at the Government
installation.

(C) It was sent by U.S. Postal Service Express Mail Next
Day Service-Post Office to Addressee, not later than
5:00 p.m. at the place of mailing two working days
prior to the date specified for receipt of proposals.
The term "working days" excludes weekends and U.S.
Federal holidays.

(D) It was transmitted through an electronic commerce
method authorized by the solicitation and was received
at the initial point of entry to the Government
infrastructure not later than 5:00 p.m. one working day
prior to the date specified for receipt of proposals.

(E) There is acceptable evidence to establish that it was
received at the activity designated for receipt of
offers and was under the Government's control prior to
the time set for receipt of offers, and the Contracting
Officer determines that accepting the late offer would
not unduly delay the procurement.

(F) It is the only proposal received.

(ii) Any modification or revision of a proposal or response to
request for information, including any final proposal
revision, is subject to the same conditions as in
subparagraphs (c)(2)(i)(A) through (c)(2)(i)(E) of this
provision.

(iii) The only acceptable evidence to establish the date of
mailing of a late proposal or modification or revision sent
either by registered or certified mail is the U.S. or
Canadian Postal Service postmark both on the envelope or
wrapper and on the original receipt from the U.S. or
Canadian Postal Service. Both postmarks must show a legible
date or the proposal, response to a request for information,
or modification

or revision shall be processed as if mailed late. "Postmark"
means a printed, stamped, or otherwise placed impression
(exclusive of a postage meter machine impression) that is
readily identifiable without further action as having been
supplied and affixed by employees of the U.S. or Canadian
Postal Service on the date of mailing. Therefore, offerors
or respondents should request the postal clerk to place a
legible hand cancellation bull's eye postmark on both the
receipt and the envelope or wrapper.

(iv) Acceptable evidence to establish the time of receipt at the
Government installation includes the time/date stamp of that
installation on the proposal wrapper, other documentary
evidence of receipt maintained by the installation, or oral
testimony or statements of Government personnel.

(v) The only acceptable evidence to establish the date of
mailing of a late offer, modification or revision, or
withdrawal sent by Express Mail Next Day Service-Post Office
to Addressee is the date entered by the post office
receiving clerk on the "Express Mail Next Day Service-Post
Office to Addressee" label and the postmark on both the
envelope or wrapper and on the original receipt from the
U.S. Postal Service. "Postmark" has the same meaning as
defined in paragraph (c)(2)(iii) of this provision,
excluding postmarks of the Canadian Postal Service.
Therefore, offerors or respondents should request the postal
clerk to place a legible hand cancellation bull's eye
postmark on both the receipt and the envelope or wrapper.

(vi) Notwithstanding paragraph (c)(2)(i) of this provision, a
late modification or revision of an otherwise successful
proposal that makes its terms more favorable to the
Government will be considered at any time it is received and
may be accepted.

(vii) An offeror may withdraw its proposal by written notice or
telegram (including ▇▇▇▇▇▇▇▇) received at any time before
award. If the solicitation authorizes facsimile proposals,
an offeror may withdraw its proposal via facsimile received
at any time before award, subject to the conditions
specified in the provision entitled "Facsimile Proposals."
Proposals may be withdrawn in person by an offeror or an
authorized representative, if the representative's identity
is made known and the representative signs a receipt for the
proposal before award.

(viii) If an emergency or unanticipated event interrupts normal
Government processes so that proposals cannot be received at
the office designated for receipt of proposals by the exact
time specified in the solicitation, and urgent Government
requirements preclude amendment of the solicitation or other
notice of an extension of the closing date, the time
specified for receipt of proposals will be deemed to be
extended to the same time of day specified in the
solicitation on the first work day on which normal
Government processes resume. If no time is specified in the
solicitation, the time for receipt is 4:30 p.m., local time,
for the designated Government office.

(3) Any information given to a prospective offeror concerning this
solicitation will be furnished promptly to all other prospective
offerors, if that information is necessary in submitting offers or if
the lack of it would be prejudicial to any other prospective offeror.

(4) Offerors may submit modifications to their proposals at any time
before the solicitation closing date and time, and may submit
modifications in response to an amendment, or to correct a mistake at
any time before award.

(5) Offerors may submit revised proposals only if requested or allowed by
the Contracting Officer.

(6) The Government will construe an offer to be in full and complete
compliance with this solicitation unless the offer describes any
deviation in the offer.

(7) Offerors may submit proposals that depart from stated requirements.
Such a proposal shall clearly identify why the acceptance of the
proposal would be advantageous to the Government. The proposal must
clearly identify and explicitly define any deviations from the terms
and conditions of the solicitation, as well as the comparative
advantage to the Government. The Government reserves the right to
amend the solicitation to allow all offerors an opportunity to submit
revised proposals based on the revised requirements.

(d) Restriction on disclosure and use of data. An offeror that includes in its
proposal data that it does not want disclosed to the public for any
purpose, or used by the Government except for evaluation purposes, must
meet both of the following conditions:

(1) Mark the title page with the following legend:

This proposal includes data that shall not be disclosed outside the
Government and shall not be duplicated, used, or disclosed--in whole or in
part--for any purpose other than to evaluate this proposal. If, however, a
lease is awarded to this offeror as a result of--or in connection with--the
submission of this data, the Government shall have the right to duplicate,
use, or disclose the data to the extent provided in the resulting contract.
This restriction does not limit the Government's right to use information
contained in this data if it is obtained from another source without
restriction. The data subject to this restriction are contained in sheets
[insert numbers or other identification of sheets].

(2) Mark each sheet of data it wishes to restrict with the following
legend:

Use or disclosure of data contained on this sheet is subject to the
restriction on the title page of this proposal.

(e) Lease award.

(1) The Government intends to award a lease resulting from this
solicitation to the responsible offeror whose proposal represents the
best value after evaluation in accordance with the factors and
subfactors in the solicitation.

(2) The Government may reject any or all proposals if such action is in
the Government's interest.

(3) The Government may waive informalities and minor irregularities in
proposals received.

(4) The Government intends to evaluate proposals and award a lease after
conducting discussions with offerors whose proposals have been
determined to be within the competitive range. If the Contracting
Officer determines that the number of proposals that would otherwise
be in the competitive range exceeds the number at which an efficient
competition can be conducted, the Contracting Officer may limit the
number of proposals in the competitive range to the greatest number
that will permit an efficient competition among the most highly rated
proposals. Therefore, the offeror's initial proposal should contain
the offeror's best terms from a price and technical standpoint.

(5) Exchanges with offerors after receipt of a proposal do not constitute
a rejection or counteroffer by the Government.

(6) The Government may determine that a proposal is unacceptable if the
prices proposed are materially unbalanced between line items or
subline items. Unbalanced pricing exists when, despite an acceptable
total evaluated price, the price of one or more contract line items is
significantly overstated or understated as indicated by the
application of cost or price analysis techniques. A proposal may be
rejected if the Contracting Officer determines that the lack of
balance poses an unacceptable risk to the Government.

(7) The unconditional written acceptance of an offer establishes a valid
contract.

(8) The Government may disclose the following information in postaward
debriefings to other offerors:

(i) The overall evaluated cost or price and technical rating of the
successful offeror;

(ii) The overall ranking of all offerors, when any ranking was
developed by the agency during source selection; and

(iii) A summary of the rationale for award.

2. 52.222-24 - PREAWARD ON-SITE EQUAL OPPORTUNITY COMPLIANCE EVALUATION (FEB
1999)

If a contract in the amount of $10 million or more will result from this
solicitation, the prospective Contractor and its known first-tier
subcontractors with anticipated subcontracts of $10 million or more shall
be subject to a preaward compliance evaluation by the Office of Federal
Contract Compliance Programs (OFCCP), unless, within the preceding 24
months, OFCCP has conducted an evaluation and found the prospective
Contractor and subcontractors to be in compliance with Executive Order
11246.

3. 552.270-3 - PARTIES TO EXECUTE LEASE (SEP 1999)

(a) If the lease is executed by an attorney, agent, or trustee on behalf
of the Lessor, an authenticated copy of his power of attorney, or
other evidence to act on behalf of the Lessor, must accompany the
lease.

(b) If the Lessor is a partnership, the lease must be signed with the
partnership name, followed by the name of the legally authorized
partner signing the same, and, if requested by the Government, a copy
of either the partnership agreement or current Certificate of Limited
Partnership shall accompany the lease.

(c) If the Lessor is a corporation, the lease must be signed with the
corporate name, followed by the signature and title of the officer or
other person signing the lease on its behalf, duly attested, and, if
requested by the Government, evidence of this authority so to act
shall be furnished.

4. 52.233-2 - SERVICE OF PROTEST (AUG 1996) (VARIATION)

(Applies to leases which exceed $100,000 average net annual rental,
including option periods.)

(a) Protests, as defined in section 33.101 of the Federal Acquisition
Regulation, that are filed directly with an agency, and copies of any
protests that are filed with the General Accounting Office (GAO),
shall be served on the Contracting Officer by obtaining written and
dated acknowledgment of receipt from the Contracting Officer at the
address shown elsewhere in this solicitation.

(b) The copy of any protest shall be received in the office designated
above within one day of filing a protest with the GAO.

5. SERVICE OF PROTEST (TSA OCT 2002)

AS A CONDITION OF SUBMITTING AN OFFER OR RESPONSE TO THIS SOLICITATION THE
OFFEROR OR POTENTIAL OFFEROR AGREES TO BE BOUND BY THE FOLLOWING PROVISIONS
RELATING TO PROTESTS.

(A) Protests concerning Transportation Security Administration (TSA)
solicitations or awards of contracts shall be resolved through the
dispute resolution system adopted by the Federal Aviation
Administration (FAA) as part of its Acquisition Management System, and
FAA's Office of Dispute Resolution (ODRA), and shall be governed by
the procedures set forth in 14 CFR Parts 14 and 17, which are hereby
incorporated by reference. Judicial review, where available, will be
in accordance with 49 USC 46110 and shall apply only to final agency
decisions. A protestor may seek review of a final decision only after

(B) Offerors initially should attempt to resolve any issues concerning
potential protests with the Contracting Officer. The Contracting
Officer should make reasonable efforts to answer questions promptly
and completely, and, where possible, to resolve concerns or
controversies. The protest time limitations, however, will not be
extended by attempts to resolve a potential protest with the
Contracting Officer.

(C) The filing of a protest with the ODRA may be accomplished by mail, by
overnight delivery, hand delivery or by facsimile. A protest is
considered filed on the date it is received by the ODRA.

(D) Only an interested party may file a protest. An interested party is
one whose direct economic interest has been or would be affected by
the award or failure to award a TSA contract. Proposed subcontractors
are not "interested parties" within this definition.

(E) A written protest must be filed with the ODRA within the time limits
set forth below, or the time set forth for the receipt of initial
proposals.

(1). Protests based on alleged improprieties in a solicitation that
are apparent prior to bid opening or the time set for receipt of
initial proposals shall be filed prior to bid opening or the time set
for receipt of initial proposals.

(2). In procurements where proposals are requested, alleged
improprieties that do not exist in the initial solicitation, but which
are subsequently incorporated into the solicitation must be protested
not later than the next closing time for receipt of proposal following
the incorporation.

(3). For protests other than those related to alleged solicitation
improprieties, the protest must be filed on the later of the following
two dates:

(i). Not later than (7) business days after the date the protester
knew or should have known of the grounds for the protest; or

(ii). If the protester has requested a post-award briefing from the
TSA Contracting Officer, not later than five (5) business days after
the date on which the Contracting Officer holds that debriefing.

(F) Protests shall be filed at:

(1) Office of Dispute Resolution for Acquisition, AGC-70.
Federal Aviation Administration
▇▇▇ ▇▇▇ ▇▇▇▇▇▇ ▇.▇.
Room 8332
Washington, DC 20590

Telephone: ▇▇▇-▇▇▇-▇▇▇▇
Facsimile: ▇▇▇-▇▇▇-▇▇▇▇ or

(2) Other addresses as specified in the solicitation.

(G) At the same time as filing the protest with the ODRA, the protester
shall serve a copy of the protest on the Contracting Officer and any
other official designated in the solicitation for receipt of protests
by means reasonably calculated to be received by the Contracting
Officer on the same day as it is to be received by the ODRA. The
protest shall include a signed statement from the protester,
certifying to the ODRA the manner of service, date, and time when a
copy of the protest was served on the Contracting Officer and other
designated official(s).

(H) Additional information and guidance about the ODRA dispute resolution
process for protests can be found on the ODRA website at
▇▇▇▇://▇▇▇.▇▇▇.▇▇▇.

PROTEST AFTER AWARD

(I) Upon receipt of a notice that a protest has been filed with the FAA
Office of Dispute Resolution (ODRA), or a determination that a protest
is likely, the Transportation Security Administrator or his designee
may instruct the Contracting Officer to direct the Contractor to stop
performance of the work called for by this contract. The order to the
Contractor shall be in writing, and shall be specifically identified
as a stop-work order issued under this clause. Upon receipt of the
order, the contractor shall immediately comply with its terms and take
all reasonable steps to minimize the incurrence of costs allocable to
the work covered by the order during the period of work stoppage. Upon
receipt of the final decision or other resolution of the protest, the
Contracting Officer shall either:

(1). Cancel the stop work order, or

(2). For other than cost-reimbursement contracts, terminate the work
covered by the work order as provided in the "Default" or the
Termination for Convenience of the Government clause(s) of this
contract; or

(3). For cost-reimbursement contracts, terminate the work covered by
the order as provided in the "Termination" clause of this contract.

(J) If a stop-work order issued this clause is cancelled either before or
after the final resolution of the protest, the Contractor shall resume
work. The Contracting Officer shall make for other than
cost-reimbursement contracts, an equitable adjustment in the delivery
schedule or contract price, or both; and for cost-reimbursement
contracts, an equitable adjustment in the delivery schedule, the
estimated cost, the fee, or a combination thereof, and in any other
terms of the contract that may be affected; and the contract shall be
modified in writing accordingly, if:

(1). The stop-work order results in an increase in the time required
for, or in the Contractor's cost properly allocable to, the
performance of any part of this contract; and

(2). The Contractor asserts its right to an adjustment within 30 days
after the end of the period of work stoppage; provided, that if the
Contracting Officer decides the facts justify the action, the
Contracting Officer may receive and act upon a proposal submitted any
time before final payment under this contract.

(K) If a stop-work order is not cancelled and the work covered by the
order is terminated for the convenience of the Government, the
Contracting Officer shall allow reasonable costs resulting from the
stop-work order in arriving at the termination settlement.

(L) If a stop-work order is not cancelled and the work covered by the
order is terminated for default, the Contracting Officer shall allow,
by equitable adjustment or otherwise, reasonable costs resulting from
the stop-work order.

(M) The Government's rights to terminate this contract at any time are not
affected by the action under this clause.

6. FLOOD PLAINS AND WETLANDS (APR 1984)

An award of contract will not be made for a property located within a base
flood plain or wetland unless the Government has determined it to be the
only practicable alternative.

1.0 SUMMARY

1.0 BY SIGNING THIS PROPOSAL, OFFERORS UNDERSTAND AND AGREE THAT THE
GOVERNMENT RESERVES THE RIGHT TO COUNTER-SIGN THEIR OFFER, WHICH SHALL
RESULT IN THE FINAL LEASE AGREEMENT BETWEEN THE PARTIES.

1.1 AMOUNT AND TYPE OF SPACE (SEP 2000)(TSA SEP 2002)

A. The Transportation Security Administration ("TSA" or
"Government") is interested in leasing approximately
450,000-550,000 ANSI/BOMA (BOMA) rentable square feet of
above-grade office space in no more than two office buildings
that are within three (3) blocks of each other. Refer to the
"ANSI/BOMA rentable square feet" paragraph in Section 3.6. Two
(2) buildings can be considered one building if they are
physically connected and employees are not required to exit
secure space or enter public space in order to move from one
building to the other.

B. The Offer shall 1) be for space located in a quality office
building(s) of sound and substantial construction as described
in this SFO, 2) have a potential for efficient layout, 3) be
within the square footage range to be considered, and 4) be in
compliance with all of the Government's minimum requirements
set forth herein.

C. To demonstrate potential for efficient layout, as well as
Offeror's ability to accommodate to Government's requirements,
Offeror will be requested to provide ANSI/BOMA calculations
and plans at the Offeror's expense, in accordance with the
instructions in Section 4.10.

D. Between 25,000 and 50,000 BOMA rentable square feet must be
ready for Government occupancy on or about January 2, 2003. An
additional 25,000 to 50,000 BOMA rentable square feet must be
ready for Government occupancy on February 1, 2003 and an
additional 25,000 to 50,000 BOMA square feet must be ready for
the Government occupancy on March 1, 2503, so that the
Government is occupying between 125,000 and 150,000 BOMA
rentable square feet on March 1, 2003. This interim space
("Phase 1") shall be substantially "as is" condition, as
further described in Section 10.2. The 450,000-550,000 BOMA
rentable square feet which TSA will ultimately occupy at its
permanent office space will be delivered through phased
construction/occupancy with the first 100,000 square feet of
Phase 2 available for occupancy on September 1, 2003, and
final occupancy of all Phase 2 and Phase 3 to be completed by
March 2004. Earlier delivery is preferred. See Section 10.2
for description of all Phases.

E. Unless otherwised noted, all references in this SFO to square
feet shall mean ANSI/BOMA (BOMA) office area square feet as
defined in Section 3.7.

1.12 NEGOTIATIONS (SEP 2000)(TSA OCT 2002)
▇. ▇▇▇▇▇▇▇▇▇▇▇▇ will be conducted on behalf of the Government by
the Contracting Officer, the Government Consultant, or the
Contracting Officer's designated representatives. The
Contracting Officer is named on the cover of this SFO. The
Government will negotiate rental price for the firm term and
any other aspect of the offer as deemed necessary.

B. The Offeror shall not enter into negotiations concerning the
space leased or to be eased with representatives of Federal
agencies other than the Contracting Officer or designee.

C. The Contracting Officer will conduct oral or written
negotiations with all Offerors that meet the requirements of
this SFO and are within the competitive range. The
competitive range will be established by the Contracting
Officer on the basis of cost or price and non-cost or price
factors as stated in this SFO and will include all of the most
highly rated proposals, unless the range is further reduced
for purposes of efficiency.

D. All Offerors will be provided a reasonable opportunity to
submit any cost or price, technical, or other revisions to
their offer that may result from the negotiations.
Negotiations will be closed with submission of final proposal
revisions ("Best and Final" offers).

1.13 PRICE EVALUATION (PRESENT VALUE)
A. If annual CPI adjustments in operating expenses are included,
the Offeror shall be required to submit the offer with the
total "gross" annual price per BOMA Office Area Square Foot
and a breakout of the "Base" price per BOMA Office Area Square
Foot for services and utilities (operating expenses) to be
provided by the Lessor. The "gross" price shall include the
"base" price.

B. The Offeror shall be required to submit plans and any other
information to demonstrate that the BOMA rentable space yields
ANSI/BOMA Office Area space within the required ANSI/BOMA
Office Area range. The Government will verify the amount of
ANSI/BOMA Office Area square footage and will convert the
rentable prices offered to ANSI/BOMA Office Area prices, which
will subsequently be used in the price evaluation.

C. If the offer includes annual adjustments in operating
expenses, the base price per ANSI/BOMA Office Area square foot
from which adjustments are made will be the base price for the
term of the lease, including any option periods.

D. Evaluation of offered prices will be on the basis of the
annual price per ANSI/BOMA Office Area square foot, including
any option periods. The Government will perform present value
price evaluation by reducing the prices per ANSI/BOMA Office
Area square foot to a composite annual ANSI/BOMA Office Area
square foot price, as follows:

1. Parking and wareyard areas will be excluded from the
total square footage but not from the price. For
different types of space, the gross annual per square
foot price will be determined by dividing the total
annual rental by the total square footage minus these
areas. For parking, the Government requires two
prices for the parking requirement as follows: one
price per each parking space offered, and one price
for TSA to use the entire garage. For evaluation
purposes, the Government will evaluate the price for
the minimum Government requirement for parking.

2. If annual adjustments in operating expenses will not
be made, the gross annual per square foot price will
be discounted annually at 8 percent to yield a gross
present value cost (PVC) per square foot.

3. If annual adjustments in operating expenses will be
made, the annual per square foot price, minus the
base cost of operating expense, will be discounted
annually at 5.1 percent to yield a net PVC per square
foot. The operating expenses will be both escalated
at 2.1 percent compounded annually and discounted
annually at 5.1 percent, then added to the net PVC to
yield the gross PVC.

4. To the gross PVC will be added:

a. The cost of Government-provided services not
included in the rental escalated at 4
percent compounded annually and discounted
annually at 8 percent.

b. The annualized (over the full term) per
ANSI/BOMA Office Area square foot cost of
any items which are to be reimbursed in a
lump sum payment. (The cost of these items
is present value; therefore, it will not be
discounted.)

c. The cost of relocation for furniture,
telecommunications, replication costs, and
other move-related costs, if applicable.

d. Cost of general contractor's overhead and
profit (OH&P) and any developers project
management fees, as a percentage of total
improvements costs based on a $40.00 per
square foot Tenant Improvement Allowance. In
no event shall the Government pay more than
a total of 16% for all fees that are related
to construction, including but not limited
to the General Owners Fee, General
Contractors General Conditions Overhead and
Profit, Construction Management Fee, and
Project Management Fee. The Architects Fee
is not included in the 16%. The Government
reserves the right to reject a General
Contractor or negotiate the General
Contractor's Fee.

e. The total rental payment for Phase I. If
rental for Phase I space is different from
phases 2 and 3, indicate as an addendum to
Attachment 1.

5. Free rent shall be discounted and evaluated in
the year in which it is offered.

6. The sum of either subparagraphs 2 and 4 or
subparagraphs 3 and 4 less 5 will be the per
ANSI/BOMA Office Area square foot present value of
the offer for price evaluation purposes.

award.

1.14 HISTORIC PREFERENCE, GSAR 552.270-2 (VARIATION)(SEP 1999)
A. Preference will be given to Offerors of space in buildings in,
or formally listed as eligible for inclusion in, the National
Register of Historic Places, and to historically-significant
buildings in historic districts listed in the National
Register. Such preference will be extended to historic
buildings and will result in award if:

1. The offer for space meets the terms and conditions of
this SFO as well as any other offer received (It is
within the discretion of the Contracting Officer to
accept alternatives to certain architectural
characteristics and safety features defined elsewhere
in this SFO to maintain the historical integrity of
the building, such as high ceilings, wooden floors,
etc.) and

2. The rental is no more than 10 percent higher, on a
total annual square foot (ANSI/BOMA Office Area) cost
to the Government, than the lowest otherwise
acceptable offer.

B. If more than one offer of an historic building is received and
they meet the above criteria, an award will then be made to
the lowest priced historic property offered.

1.15 AWARD (JAN 1997)

2.0 AWARD FACTORS

2.1 AWARD FACTORS (JAN 1997)(TSA SEP 2002)

A. Best Value Selection:
This procurement shall be conducted utilizing Best Value
Selection (BVS), which seeks to select an offer based on the
best combination of technical merit and price reasonableness
-- i.e., "best value." "Best Value" is defined as the
procurement process that results in the most advantageous
acquisition decision for the Government and is performed
through an integrated assessment and trade-off analysis
between the non-cost/price factors and the cost/price factor.
While the Government evaluation team and the Selection
Official will strive for maximum objectivity, the selection
process, by its nature, is subjective and, therefore
professional judgment is implicit throughout the entire
process.

The Government reserves the right to award a contract on the
basis of the initial offers received without discussion.
Proposals should be submitted initially on the most favorable
terms from a price and technical standpoint that the Offeror
can submit to the Government.

Advisors who are not Federal Government employees may assist
in the evaluation and provide input regarding the offers.

B. Non-Cost/Price Factors

1. Building Characteristics
Each offer will be evaluated based on the following
building characteristics subfactors. The subfactors
below are listed in order of importance and each
subfactor will be evaluated on an adjectival basis.
The adjectival ratings are: Outstanding, Acceptable,
Marginal, and Unacceptable.

a. The degree to which the building(s) meet or
can be modified to meet TSA's requirements:

i) Security features - extent to which
Level IV security requirements can
be met
ii) IT infrastructure
iii) Electrical systems
iv) Quantity, quality and suitability
of furniture, if any
v) Slab-to-slab height
vi) Finished floor-to-ceiling
achievable

b. Tenancy - Single occupancy of building(s) is
preferable to sharing buildings with another
tenant(s).

c. Number of Buildings - One building is
preferable to two buildings. Buildings side
by side are better than buildings one block
away, which is better than buildings 2
blocks away, which is better than buildings
3 blocks away.

d. Space Efficiency - The degree to which the
space offered is conducive to efficient
layout and good utilization.

e. Condition of Phase 1 Space.

f. Parking - On-site parking is better than
off-site parking. The ability to control
entire parking facility is better than the
ability to fence off part of the parking
lot.

g. Location Amenities - The greater the variety
of amenities and the closer the amenities
to the building site the better.

2. Experience and Past Performance Factor
The Government will evaluate the Offeror's
experience and past performance as a Lessor to the
Government or to other commercial or non-commercial
entities of buildings of a size and complexity
comparable to TSA's requirement. The objective of
the evaluation is to develop insight into the
Offeror's relative capability and history of
providing quality services at a reasonable price,
adherence to schedules, its history of reasonable
and cooperative behavior, and its commitment to
customer satisfaction. Offerors are cautioned that
in conducting the past performance evaluation, the
Government may use data provided by the Offeror in
its proposal and data obtained from other sources.
While the Government may elect to consider data
obtained from other sources, the burden of providing
complete information remains with the Offeror.
Experience and Past Performance factor will be
evaluated on an adjectival basis. The adjectival
ratings are: Outstanding, Acceptable, Marginal, and
Unacceptable.

C. Cost/Price Factor

The Offeror's cost/price will be evaluated in
accordance with the SFO provision entitled, "Price
Evaluation (Present Value)." The cost/price factor
will be evaluated separately from the Non Cost/Price
Factors. The cost/price factor will not be
adjectively rated. The Offeror's total evaluated
price will be assessed for reasonableness, and
realism. Reasonableness and realism will be
established by the existence of adequate price
competition and/or by comparing all, or a
representative sample of the proposed prices/costs,
to industry average rates and/or rates from other
contracts for similar work, etc.

3.0 MISCELLANEOUS

3.1 SUBSEQUENT TENANT IMPROVEMENTS $100,000 OR LESS (SEP 2000)
A. The Lessor may be requested to provide alterations during the
term of the lease. Alterations will be ordered by issuance of
GSA Form 276, Supplemental Lease Agreement, GSA Form 300,
Order for Supplies or Services, or a Tenant Agency-approved
form. The two clauses from GSA Form 3517, General Clauses,
552.232-25, Prompt Payment (Deviation FAR 52.232-25), and
552.232-70, Invoice Requirements, apply to orders for
alterations. All orders are subject to the terms and
conditions of this lease.

B. Orders may be placed by the Contracting Officer or Tenant
Agency officials when specifically authorized to do so by the
Contracting Officer. The Contracting Officer will provide the
Lessor with a list of Tenant Agency officials authorized to
place orders and will specify any limitations on the authority
delegated to Tenant Agency officials. The Tenant Agency
officials are not authorized to deal with the Lessor on any
other matters.

B. Payments for alterations ordered by the Tenant Agency will
be made directly by the Tenant Agency placing the order.

3.2 TAX ADJUSTMENT (SEP 2000)

A. Real estate taxes, as referred to in this paragraph, are only
those taxes which are assessed against the building and/or the
land upon which the building is located, without regard to
benefit to the property, for the purpose of funding general
Government services. Real estate taxes shall not include,
without limitation, general and/or special assessments,
business improvement district assessments, or any other
present or future taxes or governmental charges that are
imposed upon the Lessor or assessed against the building
and/or the land upon which the building is located.

B. Base year taxes as referred to in this paragraph are 1) the
real estate taxes for the first 12-month period coincident
with full assessment or 2) may be an amount negotiated by the
parties that reflects an agreed upon base for a fully assessed
value of the property.

C. The term "full assessment" as referred to in this paragraph
means that the taxing jurisdiction has considered all
contemplated improvements to the assessed property in the
valuation of the same. Partial assessments for newly
constructed projects or for projects under construction,
conversion, or renovation will not be used for establishing
the Government's base year for taxes.

D. The Lessor shall furnish the Contracting Officer with copies
of all notices which may affect the valuation of said land and
buildings for real estate taxes thereon, as well as all
notices of a tax credit, all tax bills, and all paid tax
receipts, or where tax receipts are not given, other similar
evidence of payment acceptable to the Contracting Officer
(hereinafter, evidence of payment), and a proper invoice (as
described in GSA Form 3517, General Clauses, 552.232-75,
Prompt Payment) of the tax adjustment including the
calculation thereof, for each year that real estate taxes are
incurred during the lease term or any extension thereof. All
such documents are due within 10 calendar days of receipt
except that the proper invoice and evidence of payment shall
be submitted within 60 calendar days after the date the tax
payment is due from the Lessor to the taxing authority.
FAILURE TO SUBMIT THE PROPER INVOICE AND EVIDENCE OF PAYMENT
WITHIN SUCH TIME FRAME SHALL BE A WAIVER OF THE RIGHT TO
RECEIVE PAYMENT RESULTING FROM AN INCREASED TAX ADJUSTMENT
UNDER THIS PARAGRAPH.

E. The Government shall 1) make a single annual lump-sum payment
to the Lessor for its share of any increase in real estate
taxes during the lease term over the amount established as the
base year taxes or 2) receive a rental credit or lump sum
payment for its share of any decreases in real estate taxes
during the lease term below the amount established as the base
year taxes. The amount of lump sum payment or rental credit
shall be based upon evidence of valuation and payment
submitted by the Lessor to the Contracting Officer in
accordance with subparagraph D.

1. In the event of an increase in taxes over the base
year, the Lessor shall submit a proper invoice of the
tax adjustment including the calculation thereof
together with evidence of payment to the Contracting
Officer. THE GOVERNMENT SHALL BE RESPONSIBLE FOR
PAYMENT OF ANY TAX INCREASE OVER THE BASE YEAR TAXES
ONLY IF THE PROPER INVOICE AND EVIDENCE OF PAYMENT IS
SUBMITTED BY THE LESSOR WITHIN 60 CALENDAR DAYS AFTER
THE DATE THE TAX PAYMENT IS DUE FROM THE LESSOR TO
THE TAXING AUTHORITY. The due date for making payment
shall be the 30th calendar day after receipt of
evidence of payment by the Contracting Officer or the
30th calendar day after the anniversary date of the
lease, whichever is later. If the lease terminates
before the end of a tax year, payment for the tax
increase due as a result of this section for the tax
year will be prorated based on the number of days
that the Government occupied the space. No increase
will be paid, due, or owing unless all evidence of
valuation and payment has been previously submitted
to the Contracting Officer. The Government's payment
for its share of real estate taxes shall not include
any late charges, interest, or penalties imposed by
the taxing authority as a result of the Lessor's
delinquency in paying such taxes or charges.

2. In the event of a decrease in taxes from the base
year, or in the event of any refund or tax deduction,
the Lessor shall notify the Contracting Officer in
accordance with subparagraph D. The Government shall
be entitled to, and shall receive a credit for, the
prorata reduction in taxes applicable to the premises
encumbered by this lease, regardless of whether the
Government has made a tax payment for that year. The
Government's share of the credit will be determined
in accordance with subparagraph F and shall be taken
as a deduction from the rent. Any credit due the
Government after the expiration or earlier
termination of the lease (including, but not limited
to, credits resulting from a decrease in taxes
pursuant to a tax credit due the Lessor; a reduction
in the tax assessment; or a tax appeal proceeding for
a year of the lease, or portion thereof) shall be
made by a lump sum payment to the Government or as a
rental credit to any succeeding lease as determined
by the Contracting Officer. The Lessor shall remit
any lump sum payment to the Government within 15
calendar days of payment by the taxing authority to
the Lessor or the Lessor's designee. If the credit
due to the Government is not paid by the due date,
interest shall accrue on the late payment at the rate
established by the Secretary of the Treasury

under Section 12 of the Contract Disputes Act of 1976
(United States Code 41 USC 611) that is in effect on
the day after the due date. The interest penalty
shall accrue daily on the amount of the credit and
shall be compounded in 30-day increments inclusive
from the first day after the due date through the
payment date. The Government shall have the right to
pursue the outstanding balance of any tax credit
using all such collection methods as are available to
the United States to collect debts. Such collection
rights shall survive the expiration of this lease.

F. The Government shall pay its share of tax increases or shall
receive its share of any tax decrease based on the ratio of
the BOMA rentable square feet occupied by the Government to
the total rentable square feet in the building or complex
(percentage of occupancy). For the purpose of this lease, the
Government's percentage of occupancy as of the date hereof is
____TBD*____ percent based upon an occupancy of ____TBD*____
BOMA rentable square feet in a building of ____TBD*____ BOMA
rentable square feet. This percentage shall be subject to
adjustment to take into account additions or reductions of the
amount of space as may be contemplated in this lease or
amendments hereto. The block and lot/parcel or other
identification numbers for other property, building(s), and
parking areas(s) occupied under this lease are ____TBD*____.

G. The Government may direct the Lessor upon reasonable notice to
initiate a tax appeal, or the Government may decide to contest
the tax assessment on behalf of the Government and the Lessor
or for the Government alone. The Lessor shall furnish to the
Government information necessary for appeal of the tax
assessment in accordance with the filing requirements of the
taxing authority. If the Government decides to contest the tax
assessment on its own behalf or on behalf of the Government
and the Lessor, the Lessor shall cooperate and use all
reasonable efforts including, but not limited to, affirming
the accuracy of the documents, executing documents required
for any legal proceeding, and taking such other actions as may
be required. If the Lessor initiates an appeal on behalf of
the Government, the Government and the Lessor will enter into
an agreement to establish a method for sharing expenses and
tax savings.

(*TBD = To Be Determined)

3.3 PERCENTAGE OF OCCUPANCY
The percent of the building occupied by the Government, for purposes
of tax adjustments, will be established during negotiations.

3.4 OPERATING COSTS (NCR NOVEMBER 2001)

A. Beginning with the second year of the lease and each year
thereafter, the Government shall pay adjusted rent for changes
in costs for cleaning services, supplies, materials,
maintenance, trash removal, landscaping, water and sewer
charges, heating, electricity, and certain administrative
expenses attributable to occupancy. Applicable costs listed on
GSA Form 1217, ▇▇▇▇▇▇'s Annual Cost Statement, when negotiated
and agreed upon, will be used to determine the base operating
cost adjustments. The agreed-upon initial operating costs
shall be stated on the SF-2 or other lease document.

B. The amount of adjustment will be determined by multiplying the
base operating costs by the percent change in the revised
Consumer Price Index (CPI) for wage earners and clerical
workers, U.S. City average, all items figure, (1982-1984 =
100) published by the Bureau of Labor Statistics, U.S.
Department of Labor.

C. The first percent change will be computed by comparing the
index figure published for the month prior to the lease
commencement date with the index figure published for the
month before the anniversary date of the lease. For example, a
lease commencing in June of 2001 would use the index published
for May of 2001 and that figure would be compared with the
index published for May of 2002 to determine the percent
change.

D. Each successive adjustment shall use the percent difference
between the prior year index figure and the current year index
figure for the month before the next anniversary date of the
lease. In the example used, the second adjustment would
compare the CPI for May of 2002 with that of May of 2003 to
determine the percent change. The percent change shall be
applied to the escalated operating costs from the previous
year. For example, if the initial operating costs were $10,000
and the initial adjustment calculated under paragraph (C)
above were $250, then the operating costs to be used for the
second adjustment calculation would be $10,250.

E. Payment will be by permanently adding 1/12 of the adjustment
to the monthly installment of fixed rent. Rental adjustments
will be effective on the anniversary date of the lease.
Payment of the adjusted rental rate will become due (for
purposes of any interest due) on the first workday of the
second month following the publication of the CPI for the
month prior to the anniversary date (adjustment effective
date).

F. If the Government exercises an option to renew the lease term,
annual adjustments will continue in the manner described
above.

G. Change in base operating costs.

SFO NO. DTSA20-03-R-00528 INITIALS: [SIG] & [SIG]
--------- ---------
15 LESSOR GOV'T

1. If a change in the operating costs occurs for such
things as commencement of daytime cleaning or
expansion of space (where the expansion space is
rented at the same rate as the original space),
annual adjustments shall be calculated separately on
the increase/decrease in operating costs. However,
such adjustment shall be effective only after the
increased costs have been in effect for at least one
year. Therefore, for expansions not ocurring on the
anniversary date of the lease, the adjustment shall
be due and payable on the anniversary date of the
lease following the first anniversary date of the
expansion. The first rent adjustment for the increase
in base operating costs shall be calculated by
comparing the CPI for the month before the effective
date of the change in base operating costs (such as
the expansion effective date) with the CPI for the
month before the lease anniversary date. For
subsequent adjustments, the increase in the base
operating costs shall be added to the other escalated
base operating costs and only one calculation shall
be made.

2. In cases where an expansion of leased space occurs
and the expansion space is rented at a different rate
than the original space, the base operating costs
shall be reestablished in the Supplemental Lease
Agreement to take the additional space. The new base
operating costs shall be a prorated blend of the
escalated original base operating costs and the base
operating costs for the new space from the GSA Form
1217 for the new space. The CPI's shall continue to
be determined as specified in paragraph (D) above,
and operating cost rental adjustments shall continue
to be made on the anniversary date of the lease.

H. In the event of a decrease in the CPI during the occupancy
under the lease, the rental amount will be reduced
accordingly. The amount of such reduction will be determined
in the same manner as increases in the rent provided under
this clause.

I. The offer shall clearly state whether the rental is firm
throughout the term of the lease or if it is subject to annual
adjustment of operating costs as indicated above. If operating
costs will be subject to adjustment, those costs shall be
specified on GSA Form 1364, Proposal to Lease Space, contained
elsewhere in this SFO. Beginning with the second year of the
lease and each year thereafter, the Government shall pay
adjusted rent for changes in costs for cleaning services,
supplies, materials, maintenance, trash removal, landscaping,
water, sewer charges, heating, electricity, and certain
administrative expenses attributable to occupancy. Applicable
costs listed on GSA Form 1217, ▇▇▇▇▇▇'s Annual Cost Statement,
when negotiated and agreed upon, will be used to determine the
base rate for operating costs adjustment.

3.5 OPERATING COSTS BASE (SEP 2002)
The base for the operating costs adjustment will be established during
negotiations based upon ANSI/BOMA Office Area square feet.

3.6 ANSI/BOMA RENTABLE SQUARE FEET (SEP 2000) (TSA SEP 2002)
For the purposes of this SFO, the Government recognizes the American
National Standards Institute/Building Owners and Managers Association
(ANSI/BOMA) international standard (Z65.1-1996) definition for rentable
space.

3.7 ANSI/BOMA OFFICE AREA SQUARE FEET (NCR VARIATION (AUG 2002)) (TSA OCT
2002)
A. For the purposes of this SFO, the Government recognizes the American
National Standards Institute/Building Owners and Managers
Association (ANSI/BOMA) international standard (Z65.1-1996)
definition for office area, which means "the area where a tenant
normally houses personnel and/or furniture, for which a measurement
is to be computed."

B. ANSI/BOMA office area square feet shall be computed by measuring the
area enclosed by the finished surface of the room side of corridors
(corridors in place as well as those required by local codes and
ordinances to provide an acceptable level of safety and/or to
provide access to essential building elements) and other permanent
walls, the dominant portion (refer to Z65.1) of building exterior
walls, and the center of tenant-separating partitions. Where
alcoves, recessed entrances, or similar deviations from the corridor
are present, ANSI/BOMA office area square feet shall be computed as
if the deviation were not present. For purposes of this
solicitation, floor common area, including rest rooms, janitors
closets, telephone and electrical closets, mechanical rooms,
elevator lobbies, and public or fire safety egress corridors are not
included as BOMA office area square feet.

3.8 COMMON AREA FACTOR (SEP 2000)
If applicable, the Offeror shall provide the Common Area Factor (a
conversion factor(s) determined by the building owner and applied by
the owner to the ANSI/BOMA office area square feet to determine the
rentable square feet for the offered space).

3.9 APPURTENANT AREAS
The right to use appurtenant areas and facilities is included. The
Government reserves the right to post Government rules and regulations
where the Government leases space.

3.10 LIQUIDATED DAMAGES, GSAR 552.270-15 (SEP 1999)

See paragraph 3.16.J.

3.11 VENDING FACILITIES (SEP 2000)
A. Approximately 500 square feet of the ANSI/BOMA rentable space in
Section 1.1 "Amount and Type of Space" will be used for the
operation of a vending facility(ies) by the blind under the
provisions of the ▇▇▇▇▇▇▇▇-▇▇▇▇▇▇▇▇ Act (United States Code 20 USC
107 et. seq.). The Government will control the number, kind, and
locations of vending facilities and will control and receive income
from all automatic vending machines. The Lessor is required to
provide necessary utilities and to make related

alterations. The cost of the improvements will be negotiated,
and payment will be made by the Government either on a
lump-sum basis or a rental increase.

B. The Government will assure that the facility(ies) does not
compete with other facilities having exclusive rights in the
building. The Offer shall advise the Government if such
rights exist.

3.12 ADJUSTMENT FOR VACANT PREMISES, GSA 552.270-16 (VARIATION)(SEP 1999)
A. If the Government fails to occupy any portion of the leased
premises or vacates the premises in whole or in part prior to
expiration of the term of the lease, the rental rate will be
reduced.

B. The rate will be reduced by that portion of the costs per
ANSI/BOMA Office Area square foot of operating expenses not
required to maintain the space. Said reduction shall occur
after the Government gives 30 calendar days prior notice to
the Lessor and shall continue in effect until the Government
occupies the premises or the lease expires or is terminated.

3.13 RELOCATION ASSISTANCE ACT (MAR 2002)
A. If an improved site is offered and new construction will
result in the displacement of individuals or businesses, the
successful Offeror shall be responsible for payment of
relocation costs for displaced persons in accordance with the

requests that the Lessor keep meeting minutes of discussion
topics and attendance. During design and construction, the
Lessor may discover instances where the Government's
directives conflict. In such cases, the Lessor shall
immediately notify the Contracting Officer so that the
Government may issue a determination as to how to proceed
beyond the building shell.

B. SPACE PLAN LAYOUTS AND PROGRAM OF REQUIREMENTS
The Government shall prepare, at the Government's expense,
Space Plan Layouts. The Space Plan Layouts will consist of
final computer generated drawings to scale showing layouts of

Government shall use best efforts to coordinate the
provision of such information and details as required
by the Lessor's architect to complete such drawings
in a timely manner. Design intent drawings, for the
purposes of this lease, are defined as
fully-dimensioned drawings of the leased space which
include enough information to prepare construction
drawings and shall consist of: 1) furniture
locations, telephone and data outlet types and
locations; 2) specifications necessary for
calculation of electrical and HVAC loads; and 3) all
finish/color/signage selections. Design intent
drawings shall be due from the Lessor within twenty
(20) working days after receipt of the space plan
layouts and program of requirements from the
Government.

2. Review. The Government retains the right to review,
approve, and request modifications (if necessary) to
the Lessor's design intent drawings prior to the
Lessor's commencement of working/construction
drawings. The Government's review and approval of the
drawings is limited as to the drawings' conformance
to the specific requirements of the SFO and the
agency's needs as they apply to the specific leased
space. The Government shall perform all reviews of
design intent drawings within fifteen (15) working
days of receipt of such from Lessor. If the
Government requires modifications to the design
intent drawings, the Government shall notify the
Lessor in writing and the Lessor shall incorporate
comments into the construction documents. Upon
approval of the design intent drawings, a notice to
proceed shall be transmitted to the Lessor, and the
Lessor shall commence working/construction drawings
for the space. At the sole discretion of the
Government, the Lessor may be required to submit a
budget proposal, based on the Tenant Improvements and
associated work as shown on the design intent
drawings. This budget proposal shall be completed
within ten (10) working days of the Government's
request. Delay of receipt of such proposal shall
result in a Lessor delay.

D. WORKING/CONSTRUCTION DRAWINGS:
The Lessor shall prepare, out of the Tenant Improvement
Allowance, final working/construction drawings for the
improvements illustrated on the Government-approved design
intent drawings. The working/construction drawings shall
include all mechanical, electrical, plumbing, fire safety,
lighting, structural, and architectural improvements scheduled
for inclusion into the Government-demised area.
Working/construction drawings shall also be annotated with all
applicable specifications. The resulting product shall reflect
requirements which are substantially the same as that
specified by the Government-approved design intent drawings
and shall incorporate neither extraneous additions nor
deletions of requirements. The Lessor's working/construction
drawings shall be due to the Government within twenty (20)
working days of the Government's approval of the design intent
drawings. Working/construction drawings shall clearly identify
1) Tenant Improvements already in place and 2) the work to be
done by the Lessor or others. The Government may also require
at the time of submission of working/construction drawings
that the Lessor submit a written price proposal along with
adequate cost and pricing data for any

--------- ---------
18 LESSOR GOV'T

costs or credits to the Government which are beyond the scope
of the original SFO and its attachments. Any work shown on the
working/construction drawings which is building shell shall be
clearly identified as such.

E. REVIEW OF WORKING/CONSTRUCTION DRAWINGS:
The Government retains the right to review, and request
modifications (if necessary) to, the Lessor's
working/construction drawings prior to the Lessor's
commencement of interior construction. The Government's
review of the working/construction drawings is limited to the
working/construction drawings' conformance to the specific
requirements of the SFO and to the approved design intent
drawings. The Government shall perform all reviews of
working/construction drawings within fifteen (15) working days
of receipt from the Lessor. If the Government requires
modifications to the working/construction drawings, the
Government shall notify the Lessor in writing. The Lessor
shall have five (5) working days to cure all noted defects
before returning the working/construction drawings to the
Government for a subsequent five (5) working day review. Upon
complete Government review for conformance of the
working/construction drawings to the design intent drawings, A
NOTICE TO PROCEED SHALL BE TRANSMITTED TO THE LESSOR, and the
Lessor shall obtain the necessary permits and shall commence
construction of the space. Notwithstanding the Government's
review of the working/construction drawings, the Lessor is
solely responsible and liable for the technical accuracy of
the working/construction drawings in meeting all requirements
and provisions of the lease and the Government-approved design
intent drawings.

F. BIDDING PROCESS
At the Government's sole discretion, the Lessor shall:

1. Provide cost and pricing data in conjunction with the
tenant alterations as specified by the Government in
Form 3517 per the terms and conditions noted therein
or,

2. Provide a price based upon the results of a
competitive bid proposal process as follows:

a. The scope of work includes the lease
(including the SFO and all SFO attachments),
the construction drawings/documents, and
written specifications. In cases of
discrepancies, the lease shall govern over
any other documents. All differences will be
resolved by the Contracting Officer in
accordance with the terms and conditions of
the lease.

b. No building shell items shall be included in
the competitive proposal.

c. A minimum of three qualified sub-contractors
must be invited to participate in the
competitive proposal process. Each
participant must compete independently in
the process.

d. Each submitted proposal must be reviewed by
the Government. The Government reserves the
right to determine if bids meet the scope of
work, that the price is reasonable, and that
the Offeror is qualified to perform the
work.

e. The Government may elect to be represented
at all negotiation sessions between the
Lessor and potential contractors.

f. The Lessor must certify to the Government
that best efforts have been made to obtain
the most competitive prices possible, that
the Lessor shall accept responsibility for
all prices through direct contracts with all
contractors, and that all performance
specifications of the lease shall be met. A
certification form, provided by the
Government, shall accompany the final bid
package.

g. The Lessor shall complete the competition
and the cost proposal process in 15 working
days or less from the date of issuance of
completed construction documents. The Lessor
shall accompany the bids with a
recommendation for selection and with a
summary in spreadsheet format comparing the
bidders' proposals and indicating the
exceptions or variations proposed by the
bidders.

h. Once the Government determines that there is
adequate competition, and upon the
Government's acceptance of the Lessor's cost
proposal based upon that competition
(provided the Lessor selects the
competition's lowest priced bid of a
contractor qualified to perform the subject
work), the Contracting Officer shall issue
to the Lessor a Notice To Proceed within 10
working days for the subject work, provided
the cost is within the Government's budget
for subject work. The NTP may be a partial
or a complete NTP, and/or in the event the
Lessor's cost proposals for the tenant
alternation work exceeds the Government's
budget, the Government may elect to have the
working drawings be value engineered by the
Lessor's construction and design team to
meet the Government's budget. The cost of
these modifications shall be paid by the
Government.

i. The Lessor shall manage and complete the
work within the timeframe/cost requirements
of the SFO and final contract.

G. CONSTRUCTION OF TENANT IMPROVEMENTS:
The Lessor shall construct all Tenant Improvements in
accordance with 1) the Government reviewed and approved
working/construction drawings and 2) all terms and conditions
of the SFO. The Lessor shall complete all Tenant Improvements
according to the Government approved project schedule and as
described in Section 10.2 and after receiving the notice to
proceed from the Government. The Lessor shall furnish a
detailed construction schedule (such as Critical Path Method)
to the Government within five (5) days of issuance of the
notice to proceed. Such schedule shall also indicate the dates
available for the Government contractors to install
telephone/data lines or equipment. The Government reserves the
right to access any space within the building during the
conduct of interior construction for the purposes of
performing inspections or for installing Government-furnished
equipment. The Government shall coordinate with the Lessor the
activity of Government contractors in order to minimize
conflicts with, and disruption to, other contractors on site.
Access shall not be denied to authorized Government officials
including, but not limited to, Government contractors,
subcontractors, or consultants acting on behalf of the
Government with regard to this project.

H. DELAYS:
Delays by the city or county in issuance of a building permit
after ▇▇▇▇▇▇ has applied for a permit with all due diligence
and delays by city or county inspections in completing
inspections necessary to issue the Certificate of Occupancy
for the building will be considered excusable delays. Owner
agrees to provide the Government a copy of the application for
the permit.

Should either the Government or the Lessor fail to discharge
their responsibilities as defined herein within the time
allocated under this construction schedule, such shall
constitute "delay." Delay caused by either party may be offset
by the early completion of that party's other responsibilities
within the schedule. The absolute value of the number of days
of one party's delay minus the number of days of the remaining
party's delay shall equal the total number of days of delay
for a given stage of the schedule. Delay shall be attributable
to the party having caused the greatest number of days of
critical path delay and shall be termed either "Government
Delay" or "Lessor Delay" as appropriate.

If Government delay occurs, then the rent commencement date
shall be the same number of days earlier than the acceptance
date as the number of days of delay. Any rental paid by the
Government prior to actual occupancy shall be less the cost
for services and utilities (Base Cost of Services) of the
vacant premises. In any event, the Government will not be
required to accept space and commence rent prior to the
original date as indicated in the "Occupancy Date" paragraph
of the SFO, unless otherwise agreed to by the Government. Each
day of Lessor Delay will be subject to the Liquidated Damages
clause of this SFO and the "Default in Delivery" paragraph of
the GSA Form 3517. In all cases of delay, the Lessor is
required to promptly notify the Government of the delay and to
provide an assessment of the impact of each delay on the
overall project schedule/budget. Along with that notification,
the Lessor is required to provide the Government with a
recovery plan outlining options for minimizing the impact of
the delay.

I. ACCEPTANCE OF SPACE:
Thirty (30) days prior to the completion of interior
construction, the Lessor shall issue written notice to the
Government to inspect the space. The Government shall have
five (5) working days to inspect and to either accept or
reject the subject space. Substantial completion is defined as
space which is fully functional with stable power (including
standby) and HVAC, suitable for the Government to begin
installation, testing and start up of critical voice/data
network and security systems.

1. Space deemed Substantially Complete by the
Government will be accepted by the Government subject to the
completion of minor punch list items. Space which is not
deemed substantially complete by the Government will not be
accepted by the Government.

The phrase "Substantially Complete" shall mean that the tenant
improvements, the common and other areas of the building, and
all other things necessary for the Government's access to the
premises and occupancy, possession, use and enjoyment thereof,
as provided in this lease shall have been completed or
obtained, including all local Government reviews and
approvals, excepting only such minor matters as do not
interfere with or materially diminish such access, occupancy,
possession, use, or enjoyment.

Should the Government reject the Lessor's space as not
substantially complete as defined herein, the Lessor shall
immediately undertake remedial action, and when ready shall
issue a subsequent notice to inspect to the Government.

2. Before the Government will accept space, the
Lessor must provide to the Contracting Officer evidence of the
issuance of a building permit incorporating the construction
of required improvements.

J. RENT COMMENCEMENT:
The rent start date for Phase I shall be ten (10) working days
after the Government accepts the space from the Lessor. The
space must be in a condition that a Certificate of Occupancy
can be issued subject to the installation of furniture. No
rent will be paid for Phase I space after the Government has
vacated the space to move into renovated space. The rent
commencement date for Phase II and III shall be ten (10)
working days after the date of space acceptance by the
Government. However, if Government delay occurs, then the rent
commencement date shall be the same number of days earlier
than the acceptance date as the number of days of delay. Any
rental paid by the Government prior to actual occupancy shall
be less than the cost for services and utilities of the vacant
premises. Each day of Lessor Delay will increase the amount of
free rent after occupancy by the Government on a day for day
basis as liquidated damages per the "Default in Delivery"
paragraph of the Form 3517.

K. ESTABLISHMENT OF LEASE TERM:
The Government shall issue GSA Form 276, Supplemental Lease
Agreement, to establish the lease term after the acceptance of
all space. The lease commencement date shall not be prior to
the rent commencement date. The commencement date for the
lease term shall be the weighted average composite of all
incremental dates of phased acceptance of Phases II and III by
the Government.

3.17 PROGRESS REPORTS (SEP 2000)(TSA SEP 2002)
After start of construction, the successful Offeror shall submit to the
Contracting Officer, written weekly progress reports. Each report shall
include information as to 1) percentage of the work completed by phase
and trade; 2) a statement as to expected completion and occupancy date;
3) changes introduced into the work; 4) analysis of changes to identify
impact on cost/schedule and provision of a recovery plan and 5) general
remarks on such items as material shortages, strikes, weather, etc.
Such meetings shall be held at a location to be designated by the
Government.

3.18 CONSTRUCTION INSPECTIONS (TSA SEP 2002)
A. Construction inspections will be made periodically by the
Contracting Officer and/or designated technical
representatives to review compliance with the SFO requirements
and the final working drawings.

SFO NO. DTSA20-03-R-00528 INITIALS: [SIG] & [SIG]
--------- ---------
20 LESSOR GOV'T

B. Periodic reviews, tests, and inspections by the Government are not
to be interpreted as resulting in any approval of the Lessor's
apparent progress toward meeting the Government's objectives but
are intended to discover any information which the Contracting
Officer may be able to call to the Lessor's attention to prevent
costly misdirection of effort. The Lessor shall remain completely
responsible for constructing, operating, and maintaining the
building in full accordance with the requirements of this SFO.

3.19 REQUIRED PROOF OF AUTHORITY (NCR VARIATION (AUG 2002))

As a condition of lease award, the Government will require one of
the following forms of proof of signing authority before the
Government executes the lease:

A. General Partnership -- Copy of Partnership Agreement

B. Limited Partnership -- Copy of Partnership Agreement or copy of
current Certificate of Limited Partnership

C. Corporation -- Corporate Resolution certified by the Secretary of
the Corporation or an Informal Action signed by the Board of
Directors. The Resolution or Informal Action must approve the lease
and indicate who has authority to sign for the corporation.

D. Joint Venture -- Copy of Joint Venture Agreement

E. Company -- Copy of formation document indicating who can bind the
company

3.20 BUSINESS IMPROVEMENT DISTRICTS (B.I.D.) (NCR VARIATION (AUG 2002)) (IF
APPLICABLE)

A. For purposes of this solicitation:

1. "BID" means a Business Improvement District, Special
Improvement District, or other specifically defined
geographical area within a taxing jurisdiction, organized and
registered pursuant to enabling legislation promulgated by a
State or local government, within which properties are
assessed, charged or taxed solely by virtue of their location
within the given area and in support of services or projects
located solely within the area.

2. "Building" means the building(s) within which space is provided
to the Government under the Lease, together with the land upon
which the building is located.

3. "Lessor's BID Assessment" means charges, assessments or taxes
levied against Lessor and/or a Building, expressed as a fixed
sum per Building, solely by virtue of the Building being
located within a BID.

B. The Government agrees, when applicable, to make a single annual
lump sum payment to the Lessor for its share of increases in
Lessor's BID Assessment over the base year. For purposes of this
clause, the base year amount of Lessor's BID Assessment will be
determined as the amount in the calendar year in which lease
commences.

C. The Government's share of increases in Lessor's BID Assessment
shall be based upon the ratio of the ANSI/BOMA Office Area square
feet occupied by the Government to the total ANSI/BOMA Office Area
square feet of office and retail space in the Building (percentage
of occupancy). Square footage related to parking will not be
included in determining the Government's percentage of occupancy.
At the Contracting Officer's sole discretion, the Government may
pay its share of increases in Lessor's BID Assessment based upon
the ratio of the assessed value of the space leased by the
Government to the total assessed value of the Building. For
purposes of this clause, the Government's percentage of occupancy
is stated in the clause of this lease entitled "Tax Adjustment".

D. The Lessor shall furnish the Government with copies of all bills
reflecting ▇▇▇▇▇▇'s BID Assessment and evidence of payment of such
Lessor's BID Assessment by the Lessor. Evidence of payment must be
submitted to the Government within 60 calendar days of the date
that payment is due. Failure by Lessor to submit evidence of
payment as provided in this paragraph shall act as a waiver of
Lessor's right to receive payment under this clause.

10.0 SPECIAL REQUIREMENTS

10.1 TRANSPORTATION SECURITY ADMINISTRATION OVERVIEW (TSA OCT 2002)

A. On November 19, 2001, the President signed into law the
Aviation and Transportation Security Act (ATSA), which among
other things, established a new Transportation Security
Administration (TSA). TSA's goal is to occupy a model
headquarters facility that looks smart and integrates
technology and daily activities to meet its needs in the year
2003 and beyond.

1. Innovative -- A workplace that supports TSA's values
of integrity, innovation, courtesy and respect,
competence, customer focus, dedication, diversity,
and teamwork.

2. High-Performance -- A workplace that serves as a
catalyst for best practices supporting new business
challenges and opportunities and an environment that
attracts and retains talented professionals.

3. Best Value -- A workplace that balances cost and
benefit. Work environments that support people and
processes, and are built to change as mission
directives evolve.

10.2 TRANSPORTATION SECURE ADMINISTRATION OBJECTIVES AND STRATEGIC APPROACH
(TSA OCT 2002)

A. TSA groups are housed in various locations throughout the
metropolitan Washington, DC area. It is imperative that TSA
collocate to a headquarters facility as quickly as possible to
effectively meet their mission directives. In addition, as
this newly formed agency is rapidly growing to full capacity,
present occupied space does not meet TSA's space requirements.
TSA's target date for commencement of occupancy is on or about
January 2, 2003.

B. TSA has developed a Strategic Project Plan which is a macro
level project approach to achieve TSA's short and long-term
goals. For the short term, TSA needs to occupy space as
quickly as possible to support its current growth. For the
long term, TSA requires a fully functional headquarters space
that will support its mission. The strategic Project Plan is
a three phased approach proposed to meet TSA's goals.

1. PHASE 1:
The strategy for Phase 1 is "as is space" which is
ready for immediate occupancy as demonstrated by the
capability to immediately obtain a certificate for
occupancy. The critical element in this phase is the
available of 25,000-50,000 ANSI/BOMA rentable square
footage of space at lease execution with the ability
for TSA to begin occupancy of the space on or about
January 2, 2003. TSA must have the ability to access
the space at the time of lease execution to begin
installation of furniture and other equipment.
Subsequently, TSA will require additional space of
25,000-50,000 ANSI/BOMA rentable square foot
increments to be available February 1, 2003 and March
1, 2003.

Phase 1 requirements are for a total of up to 150,000
ANSI/BOMA rentable square feet available for phased
occupancy. It is TSA's intention to occupy the space
with no tenant improvement beyond telecommunication
infrastructure and power connections to installed
workstations. TSA will require space to house a
temporary mailroom and provide for building entrance
security and other necessary equipment to supply the
minimum requirements for TSA's personnel to operate
within a secure office environment.

2. PHASE 2:
Phase 2 consists of new construction of the remaining
300,000-400,000 ANSI/BOMA rentable square footage
with a phased construction/delivery. The definition
of new construction is building shell specifications
as defined per the SFO, and the tenant improvements
required for final occupancy of built space. All
offered space and building systems shall be upgraded
and built out to comply with all Federal, national,
state and local codes as required per the SFO. The
Phase 2 new construction will be a phased
construction/delivery that will consist of
approximately 225,000-325,000 ANSI/BOMA rentable
square feet that will entail enclosed offices,
workstations, office support and unique/special space
build-out. The remaining 75,000 ANSI/BOMA rentable
square feet will entail the TSA joint-use spaces.

The first portion of Phase 2 will be the delivery of
100,000 BOMA rentable square feet. Planning and
construction documents development will commence at
lease execution. The Government provided Program of
Requirements and Space Plans for the first 100,000
square feet will be delivered to the Lessor 20 days
after lease execution. The 100,000 square feet shall
be available for occupancy on September 1, 2003.
Refer to Section 3.16 and 3.17 for more detailed
construction schedule information. With the phased
construction completion of each sub-phase of Phase 2
space, a portion of the Phase 1 occupants will be
relocated to Phase 2 completed space.

3. PHASE 3:
Phase 3 consists of new construction/renovation of
the up to 150,000 ANSI/BOMA rentable square footage
of Phase 1 "as is space" with phased construction
delivery. The "as is space" construction cannot begin
until enough Phase 2 space is complete for occupancy
and TSA employees have relocated from the "as is
space" to the completed Phase 2 spaces. The
definition of new construction/renovation is building
shell specifications as defined per the SFO, and the
tenant improvements required for final occupancy of
built space by March 2004.

The Phase 3 space will entail enclosed offices,
workstations, office support and unique/special space
build-out. TSA will work with the Lessor to develop
the most expedient construction project schedule to
achieve occupancy of the Phase 3 full

50 LESSOR GOV'T

tenant build-out space. With the phased construction
completion for each sub-phase of Phase 3 space, the
remaining occupants of Phase 1 space will be
relocated to Phase 3 completed space.

10.3 TYPES OF SPACE (TSA OCT 2002)

A. As a newly formed agency, TSA is still defining its space
requirements. These requirements evolve as groups identify
their mission and functions. A Master Space Study is being
developed to aid in identifying types, quantity and build out
of space.

B. Proposed tenant build out space composition includes 68%
general office space consisting of a combination of open
space, work stations, and office space, 15% unique/special
spaces housing particular functions in support of individual
TSA groups, and 17% building/joint use spaces necessary to
support TSA's operations and available for common use by the
entire agency.
