         2.       PAYMENT OF PURCHASE PRICE.

                  A.       The total purchase price to be paid to Seller by
Purchaser for the Property shall be $142,800,000 (One Hundred Forty Two Million
Eight Hundred Thousand Dollars), subject to the prorations and adjustments that
are more particularly set forth in this Contract (the "PURCHASE PRICE").

                  B.       Upon execution of this Contract, Purchaser shall
deposit with Chicago Title Insurance Co., 711 Third Avenue, New York, New York
10017, Attention: Robert Simins) (the "ESCROW AGENT") an amount equal to
$14,280,000 (Fourteen Million Two Hundred Eighty Thousand Dollars) in
immediately available funds. Such deposit shall be held by the Escrow Agent in
accordance with the terms of the Escrow Agreement annexed hereto as Exhibit D.
Said sum, together with any interest earned thereon or any additions made
thereto shall be referred to herein as the "DEPOSIT." The Deposit shall be
nonrefundable, except as expressly set forth herein. At the time of closing of
this transaction (the "CLOSING"), the Deposit shall be applied toward the
Purchase Price. At Closing, Purchaser shall remit the remainder of the Purchase
Price by wire transfer of immediately available funds to the Escrow Agent for
the account of Seller.

         3.       TITLE AND SURVEY. On or prior to the date hereof, Seller has
delivered to Purchaser a title insurance commitment (the "TITLE BINDER") from
the Escrow Agent and a current ALTA Survey of the Property, as each are more
particularly described on Exhibit E. Purchaser has approved the state of title
to the Property and all matters disclosed in the Title Binder (as anticipated to
be impacted by the Sale Order (hereinafter defined)) and Survey. At Closing,
Purchaser shall obtain a title insurance policy (the "TITLE POLICY") from Escrow
Agent and shall pay all premiums and costs and expenses in connection therewith.

         4.       CONDITION OF PROPERTY.

                  A.       The Property is being sold in "AS IS" condition
without any representations and warranties of Seller whatsoever other than as
specified in Section 13. Seller shall deliver the Property at Closing in
materially the same condition as existed on the Execution Date, ordinary wear
and tear excepted, subject to the terms of the Equipment Site Lease (hereinafter
defined) and the TSA Lease.

                  B.       Purchaser acknowledges that Seller and the Government
(hereinafter defined) will, in the ordinary course of business, be entering into
"Supplemental Lease Agreements" (each an "SLA" and collectively, the "SLAs")
with respect to the TSA Lease (as hereinafter defined), and that with respect to
those SLAs, including but not limited to those addressing the acceptance of
space each month and de minimis change orders, which do not alter any of the
material terms of the TSA Lease ("Standard SLAs"), Purchaser hereby consents to
the execution thereof by Seller on an ongoing basis prior to Closing. Seller
shall provide copies of all such Standard SLAs to Purchaser prior to their
execution. From and after the end of the Execution Date and until this Agreement
shall have terminated (or be deemed to have been terminated), Seller shall not
enter into any non-standard SLAs without Purchaser's prior consent, which
consent shall not be unreasonably withheld, conditioned or delayed.

                  C.       Purchaser hereby releases Seller from and waives all
claims, demands, actions, and causes of action against Seller and its estate for
damages, losses, expenses or injuries arising out of the condition of the
Property, including, but not limited to claims, demands, actions, and causes of
action for damages, losses, expenses or injuries arising out of preexisting
environmental conditions.

         5.       DEFECTS IN TITLE. Seller shall convey title to the Property by
special warranty deed in the form annexed hereto as Exhibit H. Title shall be
subject to all matters that are disclosed in Purchaser's Title Binder (as
modified by the Sale Order), the ATLA Survey, the Equipment Site Lease and the
TSA Lease. From and after the Execution Date, Seller shall not further encumber
or restrict the title to the Property, permit any liens, mortgages, deeds of
trust, easements or other encumbrances to be placed against the Property or any
part thereof without Purchaser's prior written consent.

         6.       CONTRACTS / LEASES.

                  A.       At Closing, Purchaser shall assume all obligations of
Seller, as Landlord, under the TSA Lease (as further described on Attachment A
to Exhibit F hereof, and together with any and all SLAs executed in accordance
with this Contract, the "TSA LEASE"), pursuant to an assignment and assumption
agreement in the form annexed hereto as Exhibit N, which shall provide, among
other things, that Purchaser shall fully indemnify Seller from and against any
and all liabilities, obligations, costs, and expenses under the TSA Lease. Upon
Closing, Seller will cooperate with the United States of America (the
"GOVERNMENT"), and Purchaser to obtain the execution by the Government of a
novation agreement by and among the Government, Seller and Purchaser regarding
the TSA Lease in the form annexed hereto as Exhibit F (the "NOVATION
AGREEMENT"). If, prior to its execution, the Government requires changes to the
Novation Agreement to be signed by Purchaser and Seller at Closing, then such
changes shall be reasonably accommodated by Purchaser and Seller.

                  B.       At Closing, Seller agrees to assign to Purchaser, to
the extent assignable, Seller's interest in the Service Contracts. Purchaser
shall execute an assumption of Seller's obligations under such Service Contracts
that arise from and after Closing in the form annexed hereto as Exhibit J.
Purchaser acknowledges that Seller does not represent or warrant that Purchaser
will be entitled to the assignment of any of the Service Contracts except to the
extent such assignment is approved by the Bankruptcy Court. If Seller is unable
to obtain Bankruptcy Court approval of the assignment of any of the Service
Contracts to Purchaser, there shall be no cost or penalty to Seller and this
Contract shall otherwise remain in full force and effect.

                  C.       At Closing, Purchaser shall assume all obligations of
Seller under the Construction Contracts pursuant to an assignment and assumption
agreement in the form annexed hereto as Exhibit K, which shall provide, among
other things, that Purchaser shall fully indemnify Seller from and against any
and all liabilities, costs, and expenses under the Construction Contracts.

         7.       CLOSING. The Closing shall occur within ten (10) days after
entry of an order of the Bankruptcy Court pursuant to, among other things,
sections 363 and 365 of the Bankruptcy

                                     - 3 -

<PAGE>

Code authorizing Seller to sell the Property to Purchaser free and clear of
liens, claims and encumbrances and consummate the transactions contemplated
herein, substantially in the form annexed hereto as Exhibit G (the "SALE
ORDER"); provided, however, that the Closing shall not occur if a temporary
restraining order, preliminary or permanent injunction or other order issued by
the Bankruptcy Court or any other court of competent jurisdiction or other
enforceable legal restraint or prohibition (collectively, "LEGAL RESTRAINTS"),
shall be in effect or pending which materially delays, restrains, enjoins or
otherwise prohibits or seeks to restrain, enjoin or otherwise prohibit the
consummation of the transactions contemplated by the Sale Order and the
transactions contemplated hereby. The Closing shall take place at the offices of
Seller's attorney during normal business hours.

         8.       PRORATIONS AND ADJUSTMENTS AT CLOSING.

                  A.       Ad valorem and similar taxes assessed against the
Property shall be prorated between Seller and Purchaser at the time of Closing
on the basis of a 365 day year, with the Purchaser liable for ad valorem and
similar taxes assessed against the Property from and after the day of Closing.
Any then due but unpaid special assessments, special improvement district or
taxing district levies, shall be prorated in the same manner as ad valorem
taxes. Seller and Purchaser shall also prorate at the time of Closing payments
under Service Contracts assumed by Purchaser, utility charges, and any other
operating expenses or other items pertaining to the Property that are
customarily prorated between sellers and purchasers in Northern Virginia
commercial real property sales. To the extent that any item, which would
otherwise be apportioned between Purchaser and Seller pursuant to the terms of
this Contract, is the obligation of tenant under the TSA Lease, such items
should not be subject to prorations under this provision. There shall be no
charge to Purchaser for supplies on hand, if any, relating to the operation and
maintenance of the Property, all of which shall be transferred to Purchaser
subject to the rights of Seller under the Equipment Site Lease and the TSA
Lease. The foregoing obligations shall survive the Closing.

                  B.       In the event that there shall be any rents or other
charges under any leases which, although relating to a period prior to Closing,
do not become due and payable until after Closing or are paid prior to Closing
but are subject to adjustment after Closing, such as rent from the Government
(as defined in Section 6(a) herein) which is paid in arrears and year-end common
area expense reimbursements (which such rent and other charges, along with any
and all past due amounts from the Government are sometimes referred to herein
collectively as the "SPECIAL RENT"), then any rents or charges of such type
received by Purchaser or its agents or Seller or its agents subsequent to
Closing shall, to the extent applicable to a period extending through Closing,
be prorated between Seller and Purchaser as of Closing and Seller's portion
thereof shall be remitted promptly to Seller by Purchaser. Purchaser
acknowledges that any Special Rent that may be received by Purchaser but due to
Seller from the Government shall be timely remitted to Seller without setoff or
deduction of any kind (it being understood that the obligation of Purchaser to
remit, and the right of Seller to receive the same is unconditional).

                  C.       Purchaser shall reimburse Seller for actual payments
made by Seller under those Construction Contracts set forth in Exhibit B annexed
hereto with respect to: (i) the warm lit shell requirements under the TSA Lease,
which amount shall not exceed $6,976,730;

                                     - 4 -

<PAGE>

(ii) tenant improvements required under the TSA Lease, which amount shall not
exceed $19,664,280; and (iii) the architectural agreement in respect of the warm
lit shell requirement under the TSA Lease, which amount shall not exceed
$157,850. At Closing, Seller shall pay a commission to Spaulding and Slye under
that certain agreement dated October 8, 2002, between Spaulding and Slye, LLC
and Seller (the "S&S AGREEMENT"), which provides for the payment of a brokerage
commission. At Closing, Purchaser shall remit to Seller in immediately available
funds the sum of $2,135,417.91 to reimburse Seller for amounts paid in
connection with the S&S Agreement.

         9.       TRANSACTION COSTS. Seller shall be responsible for the cost of
preparing the deed. At Closing, Purchaser shall reimburse Seller for the cost of
the Title Binder and the Survey. Purchaser shall pay the cost of conducting its
due diligence studies, the Title Policy, the state and local grantee's recording
taxes, sales taxes, recording fees, the escrow charges imposed by the Escrow
Agent, and transfer taxes required to be paid. Each party shall pay its own
attorneys', brokers' and consultants' fees. Pursuant to the Motion (hereinafter
defined), Seller shall request that the Sale Order entered by the Bankruptcy
Court exempt the sale of the Property under this Contract from state and local
grantee's recording taxes and transfer taxes which may be payable by reason of
the sale of the Property under this Contract or the transactions contemplated
herein (collectively, the "TRANSFER TAXES"). In the event that the Sale Order
entered by the Bankruptcy Court does not provide such an exemption and Transfer
Taxes are required to be paid in order to record the deed to be delivered to
Purchaser in accordance herewith, or in the event any such Transfer Taxes are
assessed at any time thereafter, then all such Transfer Taxes associated with
the recordation of the special warranty deed, including, without limitation,
transfer and recordation taxes and documentary stamps, shall be paid by
Purchaser at Closing or, if assessed at any time thereafter, shall be paid
promptly following such assessment. Purchaser and Seller agree to provide each
other reasonable assistance in the preparation and filing of any and all
required transfer tax returns for or with respect to such Transfer Taxes with
any and all appropriate taxing authorities.

         10.      SPECIAL WARRANTY DEED AND OTHER DOCUMENTS REQUIRED FOR

         14.      DEFAULT. If Seller is in default hereunder for failure to

REPRESENTATIVES, AND THIRD PARTY CONSULTANTS AND PROFESSIONALS FROM AND AGAINST
ANY AND ALL DEBTS, DUTIES, OBLIGATIONS, LIABILITIES, SUITS, CLAIMS, DEMANDS,
ACTIONS, CAUSES OF ACTION, DAMAGES, LOSSES, FEES, AND EXPENSES (INCLUDING,

PROPERTY WHICH HAVE ARISEN PRIOR TO THE DATE HEREOF.

                  C.       THE PROVISIONS OF THIS SECTION 15 SHALL SURVIVE
CLOSING OR ANY TERMINATION HEREOF.

         16.      RISK OF LOSS.

                  A.       If, prior to the Closing, action is initiated to take
any of the Property by eminent domain proceedings or by deed in lieu thereof,
Purchaser may either at or prior to Closing (a) terminate this Agreement, or (b)
consummate the Closing, in which latter event all of Seller's assignable right,
title and interest in and to the award of the condemning authority shall be
assigned to Purchaser at the Closing and there shall be no reduction in the
Purchase Price.

                  B.       Seller assumes all risks and liability for damage to
or injury occurring to the Property by fire, storm, accident, or any other
casualty or cause until the Closing has been consummated. If the Property, or
any part thereof, suffers any damage in excess of $5,000,000 prior to the
Closing from fire or other casualty, which Seller, at its sole option, does not
elect to repair, or if the TSA then has the right to terminate the TSA Lease as
a result of such fire or other casualty, Purchaser may either at or prior to
Closing (a) terminate this Agreement, or (b) consummate the Closing, in which
latter event all of Seller's right, title, and interest in and to the proceeds
of any insurance covering such damage (less an amount equal to any expense and
costs incurred by Seller to repair or restore the Property and any portion paid
or to be paid on account of the loss of rents or other income from the Property
for the period prior to and including the Closing Date, all of which shall be
payable to Seller), to the extent the amount of such insurance does not exceed
the Purchase Price, shall be assigned to Purchaser at the Closing. If the
Property, or any part thereof, suffers any damage less than $5,000,000 prior to
the Closing, then, provided the TSA does not then have the right to terminate
the TSA Lease as a result thereof, Purchaser agrees that it will consummate the
Closing and accept the assignment of the proceeds of any insurance covering such
damage plus an amount equal to Seller's deductible under its insurance policy
and there shall be no reduction in the Purchase Price. From the Execution Date
until Closing, Seller shall continue to maintain its casualty insurance for the
Property in substantially the same amounts and subject to substantially the same
deductibles as in existence on the Execution Date.

         17.      ASSIGNMENT. Purchaser shall not have the right to assign its
interest in this Contract without the prior written consent of Seller, which
consent may be granted or withheld in

                                     - 10 -

<PAGE>

Seller's sole and unfettered discretion, and any such assignment without such
consent shall be null and void and of no force and effect. Notwithstanding any
assignment of this Contract, Purchaser shall at all times remain primarily
obligated, and not be relieved of any liabilities, hereunder.

         18.      REPORTING OF FOREIGN INVESTMENT. Purchaser agrees to comply
with any and all reporting requirements applicable to the transaction which is
the subject of this Contract which are set forth in any law, statute, ordinance,
rule, regulation, order or determination of any governmental authority,
including but not limited to The International Investment Survey Act of 1976,
The Agricultural Foreign Investment Disclosure Act of 1978, The Foreign
Investment in Real Property Tax Act of 1980 and the Tax Reform Act of 1984 and
further agrees upon request of Seller to furnish Seller with evidence of such
compliance.

         19.      NO OFFER. The submission of this Contract to Purchaser for
review does not constitute an offer or option to sell the Property.

         20.      NOTICES. All notices and other communications hereunder shall
be in writing and shall be delivered personally against receipt or shall be sent

                  A.       Notwithstanding anything to the contrary contained
herein, this Contract, including Seller's obligations hereunder and the sale of
Property to Purchaser as contemplated hereby, is subject to (a) higher and
better offers for all or a portion of the Property, obtained pursuant to an
order of the Bankruptcy Court establishing, in form and substance satisfactory
to Seller, procedures substantially in the form annexed hereto as Exhibit Q (the
"SALE PROCEDURES ORDER") and (b) entry of the Sale Order in form and substance
satisfactory to Seller. Purchaser understands that Seller's obligations under
this Contract shall not be effective or enforceable against Seller (i) unless
and until (x) Purchaser's offer, as represented by this Contract (as hereafter
modified or supplemented) is deemed by the Bankruptcy Court to be the highest
and best offer for the Property and (y) the Bankruptcy Court has entered the
Sale Order, and (ii) if, in the Seller's exercise of its fiduciary duty, the
Seller determines, prior to the entry of the Sale Order that consummation of the
transactions contemplated hereunder is not in the best interests of its Chapter
11 estate and creditors, Seller may terminate this Contract without penalty, in
which event, the Purchaser shall be deemed to have waived all claims, damages,
actions and causes of action of whatever kind and nature (including any claims
for attorney's fees), whether known or unknown, fixed or contingent, matured or
unmatured, liquidated or unliquidated or otherwise, arising from, related to, or
concerning the Contract; provided, however, that the Purchaser does not waive
its right to recover its Deposit.

                  B.       In furtherance of the transactions contemplated
herein, the parties agree that the sale of Property to Purchaser shall be
approved in accordance with the following terms:

                           (i)      Purchaser and Seller shall cooperate with
prosecuting and obtaining entry of the Sale Order.

<PAGE>

                           (ii)     In the event (a) the request for entry of
the Sale Order is denied, or (b) the Sale Order is not entered on or before the
date which is one hundred five (105) days from the Execution Date, or (c) a
Legal Restraint of the Sale Order remains in place for thirty (30) days
following entry of the Sale Order, either the Purchaser or the Seller may
terminate this Contract without penalty, in which event, the Purchaser shall be
entitled to return of its Deposit and shall be deemed to have waived all other
claims, damages, actions and causes of action of whatever kind and nature
(including any claims for attorney's fees), whether known or unknown, fixed or
contingent, matured or unmatured, liquidated or unliquidated or otherwise,
arising from, related to, or concerning the Contract.

         31.      MARKETING. Seller shall have the right to continue to market

CONDITIONS FOR Chicago Title Insurance Company's service as escrow agent:

1.   Escrow Agent is not a party to, and is not bound by, or charged with notice
     of any agreement out of which this escrow may arise, other than this escrow
     agreement or the escrow provisions of the Contract of Sale.

2.   Escrow Agent is acting solely as a stakeholder and depository, and is not
     responsible or liable in any manner whatever for the sufficiency,
     correctness, genuineness, or validity of the subject matter of the escrow,
     or for the identity or authority of any person executing or depositing it.

                                      D-1

<PAGE>

3.   Buyer and Seller agree to jointly and severally indemnify, defend and hold
     harmless the Escrow Agent from and against any loss, cost, damage, expense
     and attorney's fee (collectively called "Expenses") in connection with or
     in any way arising out of this Escrow Agreement, other than expenses
     resulting from the Escrow Agent's own negligence or misconduct.

4.   The Escrow Agent shall be protected in acting upon any written notice,
     request, waiver, consent, certificate, receipt, authorization, power of
     attorney or other document Escrow Agent in good faith believes to be
     genuine and what it purports to be. The Escrow Agent may, at its own
     expense, consult with legal counsel in the event of any dispute or
     questions as to the construction of any provisions hereof or its duties
     hereunder, and it shall be fully protected in acting in accordance with the
     opinion or instructions of such counsel.

5.   In the event of a dispute between the Buyer and Seller, the Escrow Agent
     may continue to hold the deposits pursuant to the terms hereof, or may, at
     the joint and several cost of the Buyer and Seller, deposit the same in the
     United States Bankruptcy Court for the Southern District of New York. The
     Escrow Agent may dispose of the deposits in accordance with an order of
     said court, and shall be fully protected if it acts in accordance with any

                           FORM OF NOVATION AGREEMENT

MCI WORLDCOM NETWORK SERVICES, INC. ("Transferor"), a corporation, duly
organized and existing under the laws of the State of Delaware, with an office
at 500 Clinton Center Drive, Clinton, MS 39056, and a debtor in possession in a
voluntary case commenced under Chapter 11 of title 11, United Stated Code

duly organized and existing under the laws of the State of Maryland, with an

by and through the Transportation Security Administration, enter into this
Agreement effective as of _______________________, 2003, the date of closing.

A.       THE PARTIES AGREE TO THE FOLLOWING FACTS:

         (1)      The Government, represented by various Contracting Officers of
                  the Transportation Security Administration, has entered into a
                  certain contract (the "Lease") with the Transferor, namely:

                           Lease for real property, TSA No. DTSA20-03-R-00528
                           dated December 17, 2002, as amended by Supplemental
                           Lease Agreements more particularly described in
                           Attachment "A" which is attached hereto and made a
                           part hereof, with respect to certain premises (the
                           "Premises") which are located in Arlington, Virginia
                           and known as 601 and 701 South 12th Street.

                  The term, "the Lease," as used in this Agreement, means the
                  above lease and all other contracts, including all
                  modifications, made between the Government and the Transferor
                  before the effective date of this Agreement (whether or not
                  performance or payment have been completed and releases
                  executed if the Government or the Transferor has any remaining
                  rights, duties, or obligations under these contracts.)
                  Included in the term, "the Lease," are also all modifications
                  made under the terms and conditions of these contracts and
                  purchase orders between the Government and the Transferee, on
                  or after the effective date of this Agreement.

         (2)      As of the date hereof, the Transferor has transferred to the
                  Transferee all of its rights in and to the Lease by virtue of
                  various instruments, including, but not limited to, an
                  Assignment and Assumption Agreement between the Transferor and
                  the Transferee.

                                      F-1

<PAGE>

         (3)      The Transferee has acquired all of the rights of the
                  Transferor under and pursuant to the Lease by virtue of the
                  above transfer.

         (4)      The Transferee has assumed all obligations and liabilities of
                  the Transferor under the Lease by virtue of the above
                  transfer.

         (5)      The Transferee is in a position to perform fully all
                  obligations that may exist under the Lease.

         (6)      It is consistent with the Government's interest to recognize
                  the Transferee as the successor party to the Lease.

         (7)      Evidence of the above transfer has been filed with the
                  Government.

B.       IN CONSIDERATION OF THESE FACTS, THE PARTIES AGREE THAT BY THIS
         AGREEMENT:

         (1)      The Transferor confirms the transfer to the Transferee, and
                  waives any claims and rights against the Government that it
                  now has or may have in the future in connection with the Lease
                  (except for any amounts that are or may become due to the
                  Transferor through the date hereof, it being understood,
                  however, that only one or the other of Transferor or
                  Transferee shall have the right to pursue a claim against the
                  Government for such amounts).

         (2)      The Transferee agrees to be bound by and to perform the Lease
                  in accordance with the conditions contained in the Lease. The
                  Transferee also assumes all obligations and liabilities of,
                  and all claims against, the Transferor under the Lease as if
                  the Transferee were the original party to the Lease.

         (3)      The Transferee ratifies all previous actions taken by the
                  Transferor with respect to the Lease, with the same force and
                  effect as if the action had been taken by the Transferee.

         (4)      The Government recognizes the Transferee as the Transferor's
                  successor in interest in and to the Lease. The Transferee, by
                  this Agreement, becomes entitled to all rights, titles, and
                  interests of the Transferor in and to the Lease, and as set
                  forth in the order of the Bankruptcy Court, dated _______,
                  2003, becomes solely responsible for the payment and
                  performance of all duties and obligations of the Transferor
                  under the Lease, as if the Transferee were the original party
                  to the Lease. Following the effective date of this Agreement,
                  the term "Lessor", as used in the Lease, shall refer to the
                  Transferee.

         (5)      The Government confirms that Transferor has been released of
                  any and all obligations and liabilities under the Lease as set
                  forth in the order of the Bankruptcy Court, dated [_____],
                  2003.

                                      F-2

<PAGE>

         (6)      All payments and reimbursements previously made by the
                  Government to the Transferor, and all other previous actions
                  taken by the Government under the Lease, shall be considered
                  to have discharged those parts of the Government's obligations
                  under the Lease. All payments and reimbursements made by the
                  Government which occur within 60 days after the date of this
                  Agreement in the name of or to the Transferor shall have the
                  same force and effect as if made to the Transferee, and shall
                  constitute a complete discharge of the Government's
                  obligations under the Lease, to the extent of the amounts paid
                  or reimbursed.

         (7)      The Transferor and the Transferee agree that the Government is
                  not obligated to pay or reimburse either of them for, or
                  otherwise give effect to, any costs, taxes, or other expenses,
                  or any related increases, directly or indirectly arising out
                  of or resulting from the transfer or this Agreement, other
                  than those that the Government, in the absence of this
                  transfer or Agreement, would have been obligated to pay or
                  reimburse under the terms of the Lease.

         (8)      The Lease shall remain in full force and effect, except as
                  modified by this Agreement. Each party has executed this
                  Agreement as of the day and year first above written.

                         EQUIPMENT SITE LEASE AGREEMENT

         THIS EQUIPMENT SITE LEASE AGREEMENT ("LEASE") is effective this ____

described on Exhibit A (the "BUILDING");

         WHEREAS, Tenant is currently in occupancy of the Premises and Tenant
desires to lease said Premises from Landlord; and

         WHEREAS, Landlord also owns the real estate commonly known as Pentagon
City One at 701 South 12th Street, Arlington, Virginia ("BUILDING ONE") and the
entire property known as Pentagon City One and Pentagon City Two are sometimes
collectively referred to as "PROPERTY;"

         NOW, THEREFORE, in consideration of the rent provided for herein,
Landlord and Tenant are entering into this Lease upon the terms and conditions
set forth herein.

DEMISED PREMISES. Landlord does hereby demise and lease unto Tenant, and Tenant

and the enclosed fuel tank area (the "FUEL TANK AREA") and the enclosed utility
vault area (the "UTILITY VAULT AREA") on Level P-2 of the Building as shown on
the plan attached hereto as Exhibit B-4. The Second Floor Space, Generator Area,
Electrical Area, Fuel Tank Area, and Utility Vault Area are collectively called
the "PREMISES." Landlord and Tenant agree that the Premises shall be deemed to
contain 5,059 net rentable square feet for all purposes under this Lease,
regardless of whether the Premises might actually contain more or fewer than
5,059 net rentable square feet.

COMMON AREAS. Tenant and its officers, employees, agents, customers and invitees
shall have a nonexclusive right of access to the Parking Spaces (hereinafter
defined), the walkways, driveways and sidewalks at the Building (the "COMMON
AREAS"). Landlord agrees to make the Common Areas continuously available to
Tenant for nonexclusive use by Tenant and the other aforementioned groups of
persons during the Lease Term (as such term is hereafter defined) and any
extension thereof, except when portions of the Common Areas temporarily may be
unavailable for use by reason of repair work then being underway thereon. The
nonexclusive use of the Common Areas by Tenant and its officers, employees,
agents, customers and invitees at all times shall be subject to such reasonable
rules and regulations as Landlord from time to time may establish and shall be

                                      O-1

<PAGE>

Landlord shall have the right from time to time temporarily to close the Common
Areas to prevent the acquisition of public rights therein. Landlord shall
operate and maintain the Common Areas during the Lease Term and any extensions
thereof in good order and repair in accordance with the standards of comparable
buildings in the area in which the Premises are located.

LEASE TERM. This Lease shall commence on the date of this Lease (the
"COMMENCEMENT DATE") and shall terminate at 11:59 p.m. of the last day of the
month that is ten (10) years thereafter (the "INITIAL LEASE TERM"), subject to
Tenant's Options to Renew, as set forth in Section 0 of this Lease. As used in
this Lease, "LEASE TERM" means the Initial Lease Term and any then applicable
Renewal Term (as defined in Section 0). As used in this Lease, "LEASE YEAR"
means the period from the Commencement Date through the twelfth full month of
the Initial Lease Term with respect to the first Lease Year and each successive

days to pay such additional charges or other amount due to Landlord following

supporting documentation. Base Rent and any other sums due hereunder are
sometimes collectively called "RENT."

security devices to maintain security in the Premises. Tenant may use, occupy
and operate the Premises for any lawful use, including without limitation, the

and any other uses permitted by the applicable zoning code. Without limiting the
foregoing, Tenant shall have the right, at no additional charge or rent, to
install, operate, replace, expand, add to, repair and maintain its fiber optic
cable and related equipment in horizontal and vertical shafts, risers and
pathways to the Building and/or Building One for the purpose of (i) providing
telecommunications services (installation of a point of presence) to other

affiliates, and (ii) interconnecting telecommunications equipment of Tenant, its
customers or vendors throughout the Building, Building One and surrounding

and any extensions thereof to comply with all applicable laws affecting the use
of the Premises.

Landlord acknowledges that the Building contains cables and conduits and related
equipment within the Building and throughout the Property that service the
Premises. All such conduits and cables present in the Building and the Property
shall remain in place and not be disturbed without Tenant's written consent.
Landlord shall provide 24 hour, 7 day per week access to such additional riser
space or comparable areas to Tenant for electrical, generator, telecom, antenna,
dish or HVAC requirements at no additional rent as needed by Tenant throughout
the Lease Term. Additional space provided pursuant to this Section 0 shall be
provided at no additional cost to Tenant, although Tenant shall be responsible
for the cost of the conduit installation.

Landlord acknowledges and agrees that Tenant's contemplated use of the Premises
may include the installation, operation, maintenance, repair and replacement of
telecommunications equipment and related facilities by Tenant's customers and
vendors (the "COLLOCATES"). The Collocates shall be entitled to use the Premises
at no additional charge and without requiring the consent of Landlord. The
Collocates shall have the right to bring fiber and related facilities into the
Premises through the conduits and space utilized by Tenant at no additional
charge and without requiring the consent of Landlord.

LANDLORD'S COVENANTS/TENANT'S RIGHT TO 24 HOUR, 7-DAY PER WEEK ACCESS. Landlord
covenants that: (a) it is the owner of the real estate described in Exhibit A;
(b) the Premises at all times during the Lease Term and any extension thereof
will have unobstructed ingress and egress to the entrance of the Premises and a
public street or highway; (c) Landlord has full power and capacity to make this
Lease with Tenant; and (d) throughout the Lease Term, the Building will comply,
with all laws, ordinances, orders, rules, regulations and requirements of all
federal, state, municipal and local governmental bodies exercising jurisdiction
thereover, whatever the nature of such same, including without limitation,
environmental rules and regulations and the Americans With Disabilities Act, as
amended ("ADA"), and Tenant shall not be liable or responsible to assure that
the Building complies with the same nor for any latent defects in the Premises
or Building. Landlord covenants and agrees: (i) to use its best efforts to avoid
taking any actions that might adversely affect Tenant's use of or business
operations within the Premises, including but not limited to, any actions that
might adversely affect Tenant's fiber optic cabling or telecommunications
equipment; (ii) to provide Tenant with at least forty-eight (48) hours' prior
written notice if, notwithstanding Landlord's best efforts, Landlord must take
an action that might adversely affect Tenant's use of or business operations
within the Premises; (iii) in all events to coordinate and cooperate with Tenant
to minimize any cessation or degradation of Tenant's use of, or business
operations within, the Premises; (iv) to take such actions as soon as reasonably
practicable as may be necessary to correct or cure any acts, events or
circumstances that may have adversely affected Tenant's use of or business
operations within the Premises; and (v) to allow Tenant access to the Premises,
the roof and the Building including the HVAC Systems and Back-up Systems (as

<PAGE>

seven (7) days a week. Landlord further covenants that Tenant, upon the complete
and timely payment of Rent and performance of Tenant's other obligations under
this Lease, shall peacefully and quietly have, hold and enjoy the occupancy of
the Premises throughout the Lease Term and any extensions thereof, or until this
Lease is sooner terminated in accordance with its provisions, without any
disturbance.

MECHANICS' LIENS. Tenant shall not permit any mechanics', laborer's, or
materialman's lien to stand against the Premises for any labor or material
furnished to Tenant or claimed to have been furnished to Tenant in connection
with work of any character performed or claimed to have been performed on the
Premises by or at the direction of Tenant and shall hold Landlord and the
Premises harmless therefrom. Tenant promptly shall pay all contractors and
materialmen so as to minimize the possibility of a lien attaching to the
Premises. Tenant may contest in good faith the validity of any liens so filed
and shall not be obligated to pay or discharge any such lien until the same has
been adjudged valid by the final judgment of a court of competent jurisdiction;
provided that the interests of Landlord in the Premises shall be fully protected
against such lien during the period of any such contest.

LANDLORD'S SERVICES.

LANDLORD'S GENERAL SERVICES.  Landlord shall provide the following services:

public water from the regular Building fixtures for drinking, lavatory and
toilet purposes and as required for Tenant's HVAC equipment only;

passenger elevator service and freight elevator service in common with Landlord,
other tenants and visitors to the Building on a 24-hour per day, 7-day per week
basis including holidays; and

electrical service as specified in Section 0. Additional electrical capacity or
usage shall be provided with the consent of Landlord (which shall not be
unreasonably withheld, conditioned or delayed) and at Tenant's expense.

DELAYS IN FURNISHING SERVICES. If any failure to furnish or delay in furnishing
any of the services described in Section 0 prevents and will continue to prevent
Tenant from using the Premises as it is then using the Premises or prevents and
will continue to prevent Tenant from providing the telecommunications services
being provided by Tenant to its customers ( such a condition of the Premises
being hereinafter referred to as "UNTENANTABLE" or "UNTENANTABILITY"), then,
commencing upon the date when the Premises became Untenantable, all Rent shall
abate for the duration of such Untenantability. Tenant agrees that Landlord
shall not be liable for damages for failure to furnish or delay in furnishing
any service if attributable to any of the causes described in Section 0.

exterior of the Building and the Building Systems, at Landlord's cost and
expense. The "BUILDING SYSTEMS" means the base building

                                      O-4

other casualty. Tenant shall have the right to remove Tenant's generator, fuel
storage equipment and HVAC equipment located outside the Premises within one
hundred and twenty (120) days after the termination of the Lease, but Tenant
shall not be obligated to do so. Tenant shall remove its equipment, furniture
and fixtures within six (6) months following the expiration date. Tenant shall
cap and safely cut all cabling, but Tenant shall not be obligated to remove any
raised flooring or any conduit or cabling. Tenant shall not otherwise be
required to (although Tenant may elect to) remove any improvements made by
Tenant to the Premises.

CLEANING. Tenant shall, at Tenant's expense, hire its own cleaning contractor to
clean the Premises. Tenant's cleaning contractor, cleaning personnel and all
aspects of Tenant's cleaning of the Premises shall be subject to all Building
security and other requirements as Landlord might impose from time to time.

INSURANCE. Tenant, at its expense, at all times during the Lease Term and any
other period of occupancy of the Premises by Tenant, shall provide and maintain
with respect to the Premises Commercial General Liability insurance in form
customarily written for the protection of owners, landlords and tenants of real
estate, with Landlord as an additional insured, which insurance shall provide
coverage of not less than $1,000,000.00 for bodily injury and property damage.
Any insurance required to be maintained by Tenant may be provided through a
blanket policy covering the Premises and other properties. Landlord, at its
written request, shall be furnished with appropriate certificates evidencing
that such insurance is in force and that Landlord is named as an additional
insured thereunder. The policies for all such insurance shall provide that they
not be canceled without at least ten (10) days' prior written notice to
Landlord.

HAZARD INSURANCE. Landlord at all times during the Lease Term and any other
period of occupancy of the Premises by Tenant shall provide and maintain, at
Landlord's expense,

                                      O-5

comprehensive fire insurance with extended coverage insuring the Building,
providing such level of coverage and insuring against such risks as are
customarily maintained with respect to comparable buildings in the market in
which the Premises is located.

ELECTRIC. A 6,000 amp electrical main service current services the Building.
Landlord shall have the right to elect at any time, at Landlord's expense, to
install a separate meter, a submeter or a check meter to monitor electricity
usage at the Premises. Upon installation of such monitoring meter, Tenant shall
be billed directly by the provider (if Tenant is directly metered) and Tenant
shall pay for its electric service directly to the power provider, or Tenant
shall be billed by Landlord (if Tenant's electricity usage is separately
monitored, but not directly metered) for the electricity usage at the Premises
and/or electricity usage of the Specialty Equipment, as the case may be, at
utility company rates without markup by Landlord. Until the Premises is so
metered, the cost of Tenant's electricity usage shall be included in the Base
Rent. Subject to electric service outages and reductions outside the control of
Landlord, Landlord shall allocate 800 amps, 480 volts, three (3) phase, four (4)
wire electrical service to the Premises. If Tenant requires additional capacity
at any time during the Lease Term, Landlord shall use commercially reasonable
efforts to assist Tenant in securing the additional power requirement from the
power provider and providing additional space for additional capacity, at
Tenant's expense, for such additional space provided.

SIGNAGE. If Tenant so requests, Landlord agrees to display Tenant's name on the
Building lobby sign in the same fashion as the other tenants' names are
displayed, at Landlord's cost and expense.

TRADE FIXTURES, SPECIALTY EQUIPMENT.

Tenant may, from time to time during the Lease Term, install, maintain, replace,
repair, expand, construct and operate at the Premises and remove therefrom such
trade fixtures as it may deem necessary or appropriate to its business
operations, including but not limited to the Specialty Equipment (as defined
below); provided that any damage that may be caused to the Premises by the
removal of any of Tenant's trade fixtures or Specialty Equipment shall be
repaired by Tenant at its expense forthwith upon the removal of any such trade
fixtures or Specialty Equipment.

Landlord grants to Tenant the right, at no additional charge or rent, to
install, operate, expand, add to, repair and maintain, and Landlord acknowledges
that Tenant's use of the Premises will require, some or all of the following
(collectively, the "SPECIALTY EQUIPMENT"):

fiber optic cabling from two (2) separate means of entry from the adjoining
streets, across the Building's surrounding grounds (at locations indicated on
the Declaration of Easement of even date for the benefit of Tenant, which is
recorded or to be recorded in the Land Records of Arlington County, Virginia),
to, and core drilling of, the Building core structural wall and from the
Building core structural wall, by two (2) diverse paths, to the Premises;

heat, air conditioning and ventilation for the Premises on a 24-hour, 7-day per
week basis, including holidays to the extent necessary for the comfortable
occupancy of the Premises under normal business operations with customary office
equipment and in the absence of the use of any

                                      O-6
<PAGE>

non-customary machines, equipment or devices which adversely affect the
temperature otherwise maintained in the Premises;

batteries in the Premises for power backup in case of power failure;

an independent, Tenant-controlled fire suppression system which will include
access to Tenant for exhaust louvers, shafts or risers necessary for the

alarm system;

a raised floor system to accommodate Tenant's telecommunications equipment;

a 750 MCM copper insulated ground conductor in one and one-half inch (1.5")
conduit from the master ground at the lowest point in the Building to the
Premises; and

the installation of interior walls or window covering materials to stabilize
environmental conditions within the Premises.

In addition to the generator and electrical equipment in the Generator Area,
Tenant shall have the right to install and maintain up to a 5,000 gallon fuel
tank system in the area shown on Exhibit B-4, and UPS in the Building and/or the
Property ("BACK-UP SYSTEMS") and shall have the right to maintain such
installations in the locations shown on Exhibit B-2 and Exhibit B-4 throughout
the Lease Term, as renewed at no additional charge or rent. Tenant maintains
certain mechanical cooling systems in the Building in the location shown on
Exhibit B-3 (collectively, "HVAC SYSTEMS") and Tenant shall have the right to
maintain such systems throughout the Lease Term, as renewed. Tenant shall have
24-hour, 7-day per week access to the Back-up Systems and the HVAC Systems.
Landlord shall provide such space, including the right to install necessary
connections therefrom to the Premises, at no additional charge or rent to
Tenant. Tenant shall have the right to test its generator(s)at any time, which
testing shall be conducted in compliance with all applicable laws, codes, and
regulations.

During the Lease Term and any extension thereof, Tenant shall have the right, at
no additional rent, to install GPS and/or other antenna(s) and dish(es) on the
roof or the grounds of the Building (including all necessary connections to the
Premises, along with the benefit of any easements that might be required in
connection therewith) for use by Tenant and/or Tenant's Collocates. Any such
antennas or dishes shall be installed in accordance with all applicable laws and
building codes and in locations mutually agreeable to Landlord and Tenant.
Tenant shall have the option to remove such antennas and dishes at the
expiration or earlier termination of this Lease; provided that in the event of
removal, Tenant shall repair any damage to the roof or grounds of the Building
caused by such removal. Landlord shall provide the space for such antennas,
dishes, and necessary connections at no additional charge or rental to Tenant.

Tenant, at Tenant's sole cost and expense, shall have the right to construct a
dry pipe, preaction system for the Premises, including the right to relocate or
encase any water mains or other water pipes running through the Premises to
lessen the potential damage to Tenant's equipment. Landlord agrees to provide
sufficient flow and pressure in the standpipe to the Premises to

                                      O-7
<PAGE>

support such a fire suppression system. Landlord agrees that Tenant may remove
all of the existing wet sprinklers in the equipment areas of the Premises,
although those support areas of the Premises on which no equipment is located
and the Common Areas will remain on the Building's wet sprinkler. The preaction
system shall only be located in the Premises and will be connected to the
Buildings alarm system in accordance with all applicable laws and building
codes. Tenant shall also have the right, at Tenant's expense, to install an FM
200 fire suppression system in the Premises.

FLOOR LOAD. Tenant, at Tenant's sole cost and expense, shall have the right but
not the obligation, with the prior consent of Landlord, which consent shall not
be unreasonably withheld, conditioned or delayed, to reinforce the floors in the
Premises so as to allow additional floor load thereon. Landlord will allow
Tenant to reinforce floors in the Building outside the Premises, provided
Landlord shall have the right to direct Tenant as to the method of such
reinforcement.

ALTERATIONS BY TENANT. Tenant, at its expense, may, from time to time during the
Lease Term, make such nonstructural alterations to the interior of the Premises
as Tenant deems appropriate to its business operations without Landlord's
consent; provided that all such alterations shall be completed in a good and
workmanlike manner and shall not impair the structural soundness of the
Premises. Tenant shall make no additions or alteration whatsoever to the
exterior of the Premises and no structural changes whatsoever within the
Premises without the prior written consent of Landlord, which consent shall not
be unreasonably withheld, conditioned or delayed.

MUTUAL INDEMNIFICATION; LIMITATION OF LIABILITY.

Landlord agrees to indemnify Tenant against and to defend and hold Tenant
harmless from any and all claims, demands, damages, penalties, costs,
liabilities and losses arising from or based upon any alleged act, omission or
negligence of Landlord or Landlord's agents or employees or arising from or
based upon any breach of Landlord's covenants under this Lease. Tenant agrees to
indemnify Landlord against and to defend and hold Landlord harmless from any and
all claims, demands, damages, penalties, costs, liabilities and losses arising
from or based upon any alleged act, omission or negligence of Tenant or Tenant's
agents or employees or arising from or based upon any breach of Tenant's
covenants under this Lease.

Neither Landlord nor Tenant, nor any of their respective employees, agents or
contractors shall be liable under any theory of liability to the other for
indirect, special, incidental, remote, or consequential damages arising under or
in connection with this Lease, whether in an action for or arising out of breach
of contract, tort, or otherwise.

WAIVER OF CLAIMS; WAIVER OF SUBROGATION. Each party hereto hereby waives any and
all claims for recovery which such party or anyone claiming through such party
may have against the other party hereto (or such other party's officers, agents
or employees) for or with respect to any loss of or damage to such waiving
party's property that is (i) insured under valid insurance policies, to the
extent of any recovery actually collectible under such insurance policies, or
(ii) required by this Lease to be insured, to the extent any recovery would be
collectible if such insurance policies were obtained and maintained as required
by this Lease, whether or not such loss or damage is caused by the negligence of
such other party or such other party's agents,

                                      O-8

<PAGE>

employees, subtenants, concessionaires or licensees or of any other person or
persons for whose actions such other party may be responsible or liable.
Landlord and Tenant each agree to obtain from the insurance companies providing
its insurance applicable hereto permission to allow Landlord and Tenant to waive
their respective insurance companies' rights of subrogation. Landlord and Tenant
shall each provide to the other written proof of the waiver of said claims by
said insurance companies.

ENTRY BY LANDLORD. Landlord shall have the right to enter the Premises only upon
reasonable prior notice and accompanied by a representative of Tenant, for the
purpose of inspecting the Premises or for the purpose of making repairs thereto;
provided that such entry shall not materially interfere with the conduct of the
Tenant's business as determined by Tenant in its sole discretion and that
Landlord shall reimburse Tenant for all costs reasonably incurred by Tenant as a
result or in accommodation of Landlord's repairs. Landlord acknowledges that
Tenant's use of the Premises will include installation of sensitive equipment;
therefore, during the Lease Term or any extension thereof, Landlord shall have
no right to install conduits or other piping in or through the Premises or
through the Building or the roof of the Building, including, without limitation
the walls, ceilings and floors of the Premises or areas above or below the
walls, ceilings and floors without Tenant's consent.

DAMAGE BY CASUALTY. In case the Premises, or any part thereof, shall at any time
be destroyed or damaged by fire or other unavoidable casualty, so that the same
shall be unfit for occupation or use by Tenant for its purposes hereunder, then
the Rent hereby reserved, or a fair and just proportion thereof, according to
the nature and extent of the damage sustained in loss of occupation of the
Premises, shall be suspended, cease to be payable and so continue until said
Premises shall be rebuilt or made fit for occupation and use, or if such damage
to the Premises or to the Building (regardless of whether the Premises are
affected) is to the extent of fifty percent (50%) or more, then this Lease may
be terminated at the election of Landlord or Tenant, notice of which election,
if exercised, shall be given in writing within fifteen (15) days from date of
casualty. If this Lease is not so terminated within such time period, then
Landlord shall be deemed to have agreed to repair and restore the Premises and
the Building. The length of time that Landlord shall have to make such repairs
hereunder shall in no event exceed a period of six (6) months from the date of
casualty. If Landlord fails to complete such repairs within said six (6) month
period, Tenant shall have the option (i) to terminate this Lease as of the date
of such casualty by giving written notice to Landlord not later than thirty (30)
days after said six (6) month period or (ii) to exercise any and all rights
necessary to cause Landlord to complete such repairs, including, without
limitation, collection of damages.

BANKRUPTCY.

Landlord acknowledges that on July 21, 2002, Tenant and certain of its domestic
affiliates filed voluntary petitions for relief under Chapter 11 of title 11,
United States Code (the "BANKRUPTCY CODE") in the United State Bankruptcy Court
for the Southern District of New York. Tenant is continuing to operate its
business and manage its properties as a debtor in possession pursuant to
sections 1107(a) and 1108 of the Bankruptcy Code. This Section 0 shall not apply
to such bankruptcy filing nor shall Tenant be deemed to be in default of this
Lease as a result of such bankruptcy filing.

                                      O-9
<PAGE>

Subject to Section 0, the filing by or against Tenant of any petition in
bankruptcy, or the adjudication of Tenant as a bankrupt or insolvent, or the
appointment of a receiver or trustee to take possession of all or substantially
all of the assets of Tenant, or the making of a general assignment by Tenant for
the benefit of creditors, or any action taken or suffered by Tenant under any
state or federal insolvency or bankruptcy act, or the levy of execution or
attachment against Tenant's interest in the Premises, and the continuance of any
of the same for a period of ninety (90) days, shall constitute a breach of this
Lease forthwith upon written notice to Tenant. The parties understand and agree
that neither this Lease nor any interest herein or hereunder, nor any estate
created hereby shall pass by operation of law under any state or federal
insolvency or bankruptcy act to any trustee, receiver, assignee for the benefit
of creditors or any other person whomsoever without the express prior written
consent of Landlord. Any purported transfer in violation of the provisions of
this Section shall constitute a breach of this Lease; and in such event,
Landlord may, at its option, with written notice, declare this Lease terminated
forthwith.

HOLDING OVER. Provided Tenant is not in default under the terms and conditions
of this Lease beyond the applicable notice and cure period, Tenant shall have
the one time option to extend the Lease Term (or any Renewal Term) for an
additional six (6) month period, otherwise subject to all the terms and
conditions of this Lease. Such option may be effectuated only by written notice
to Landlord given no later than twelve (12) months prior to expiration of the
Lease Term (or the applicable Renewal Term). Additionally, provided Tenant is
not in default under the terms and conditions of this Lease beyond the
applicable notice and cure period, Tenant shall have the option to continue this
Lease on a month-to-month basis (the "HOLDING OVER PERIOD") commencing upon the
day after the date on which the Lease Term or the term of any extensions granted
under this Lease expire. The Base Rent for the first four (4) months of the
Holding Over Period shall be 100% of the Base Rent in effect at the end of the
Lease Term, payable on the first day of each month. Thereafter, Base Rent for
the Holding Over Period shall be 125% of the Base Rent in effect at the end of
the Lease Term, payable on the first day of each month. The Holding Over Period
shall otherwise be subject to all the terms and conditions of this Lease. This
option shall be effectuated by Tenant either notifying Landlord in writing of
Tenant's decision to exercise said option not less than thirty (30) days prior
to the end of the Lease Term or by Tenant remaining in possession of the
Premises after the expiration or termination of the Lease Term without the
execution of a new lease.

WAIVERS. One or more waivers by Landlord or Tenant of a breach of any covenant
or condition by the other of them shall not be construed as a waiver of the
subsequent breach of the same covenant or condition, and the consent or approval
by Landlord or Tenant to or of any act by either requiring the other's consent
or approval shall not be deemed to waive or render unnecessary either party's
consent to or approval of any subsequent similar act by the other party.

NOTICES. All notices or other communications which are required or permitted
herein shall be in writing and deemed sufficiently given if delivered by (i)
certified or registered mail, postage prepaid, return receipt requested, (ii) by

in all correspondences and notices from Landlord to Tenant under this Lease
reference to Tenant's internal lease number assigned to this Lease by Tenant
following execution of this Lease (the "LEASE NUMBER," as shall be set forth on
the cover page of this Lease.

DELAYS IN PERFORMANCE. The performance by Landlord or Tenant of any of their
respective obligations or undertakings provided for in this Lease (except the
payment of Rent or any other sums of money payable by Tenant under this Lease)
shall be excused and no default shall be deemed to exist in the event and so
long as the performance of any such obligation or undertaking is prevented,
delayed, retarded or hindered by an act of God, fire, earthquake, flood,
explosion, action of the elements, war, riot, failure of transportation,
strikes, lockout, action of labor unions, condemnation, laws, orders of
government or civil or military authorities, inability to procure labor,
equipment, facilities, materials or supplies in the open market, or any other
cause beyond the reasonable control of Landlord or Tenant, as the case may be.

DEFAULT.

TENANT DEFAULT. If Tenant defaults in the payment of any Rent or other sums due
and payable to Landlord under this Lease and such default continues for a period
of thirty (30) days after written

                                      O-11
<PAGE>

notice of such default has been given by Landlord to Tenant, or if Tenant shall
violate or default in the performance of any covenants, agreements, stipulations
or other conditions contained herein (other than the payment of rent and other
sums) for a period of thirty (30) days after written notice of such violation or
default has been given by Landlord to Tenant or, in the case of a default not
curable within thirty (30) days, if Tenant shall fail to commence to cure the
same within thirty (30) days, and thereafter proceed diligently to complete the
cure thereof, then Landlord, at its option, may re-enter and repossess the
Premises in accordance with applicable law, and declare this Lease terminated
and the Lease Term ended forthwith. Except for the negligence or intentional
misconduct of Landlord, its agents or employees, Landlord shall not be liable
for damages by reason of such re-entry and repossession. Notwithstanding such
re-entry and repossession by Landlord, the liability of Tenant for the payment
of the Rent and other sums due hereunder and for the performance of Tenant's
other obligations hereunder for the balance of the Lease Term shall not be
relinquished or extinguished; and Landlord at any time may commence such one or
more actions as it may deem necessary to collect any sums due from Tenant under
this Lease. In the event of any such re-entry and repossession, Landlord shall
have the right to relet all or any portion of the Premises upon such terms and
conditions as may be reasonable; and any such reletting shall not relieve Tenant
of any of its obligations to Landlord under this Lease, except to the extent of
any net rents actually received by Landlord from such reletting after deduction
of all of Landlord's reasonable expenses (including but not limited to legal
expenses and brokerage commissions) incurred in accomplishing such reletting.
Landlord agrees to attempt to mitigate its damages by making reasonable efforts
to relet the Premises on reasonable terms.

LANDLORD'S DEFAULT. In the event Landlord fails to observe and perform any
covenant or obligation required to be observed or performed by Landlord under
this Lease and such failure of performance continues for a period of thirty (30)
days after written notice thereof from Tenant to Landlord (unless such failure
cannot reasonably be cured within such thirty (30) day period and Landlord shall
fail within such period to commence and diligently pursue the curing of such
failure), Tenant may undertake all reasonable action to cure Landlord's failure
of performance and Landlord agrees to reimburse Tenant on demand for all sums
expended or obligations incurred by Tenant in connection therewith (including
reasonable attorneys' fees). If Landlord does not reimburse Tenant within thirty
(30) days of receipt of an invoice therefor, Tenant shall have the right to set
off said amount from the Rent payable by Tenant to Landlord hereunder. In
addition thereto and not in limitation thereof, in the event Landlord's failure
of observance of its covenants and agreements contained herein renders Tenant's
Premises Untenantable, materially disrupts the operation of Tenant's business,
or continues beyond the above cure period, Tenant may, without prejudice to its
right to recover damages for breach, terminate this Lease by written notice to
Landlord, remove its personal property and trade fixtures, vacate the Premises
and employ, and have full recourse to, all other rights and remedies available
by operation of law or equity.

CUMULATIVE RIGHTS. The rights, options, elections and remedies of both parties
contained in this Lease shall be cumulative and may be exercised on one or more
occasions; and none of them shall be construed as excluding any other or any
additional right, priority or remedy allowed or provided by law.

EMINENT DOMAIN. If the whole or any part of the Premises hereby leased shall be
taken by any public authority under the power of eminent domain, then the Lease
Term shall cease on the part so taken from the day the possession of that part
shall be required for any purpose, and the Rent shall be paid up to that day,
and if such portion of the Premises is so taken as to destroy (in Tenant's
reasonable discretion) the usefulness of the Premises for the purpose for which
the Premises were leased, then, the Tenant shall have the right either to
terminate this Lease and declare the same null and void or to continue in the
possession of the remainder of the same under the terms herein provided, except
that the Rent shall be reduced in proportion to the amount of the Premises
taken. All damages awarded for such taking shall belong to and be the property
of the Landlord, including such damage as shall be awarded as compensation for
diminution in value to the leasehold; provided, however, that Tenant shall be
entitled to any portion of the award made to the Tenant for its leasehold
improvements and relocation expenses and Tenant shall have the right to file
separately for any such claim.

PERSONAL PROPERTY. All personal property in the Premises shall be at the risk of
the Tenant only and the Landlord shall not be or become liable for any damage to
said personal property, including any damage to said personal property caused by
water leakage, steam, sewer gas or odors, or done or occasioned by or from, any
boiler, plumbing, gas, water, steam or other pipes or any fixtures, equipment or
appurtenances whatsoever, or occasioned by water, snow or ice, being upon or
coming through the roof, sky-light, trap door, or otherwise arising from any
defect in the Building or any of the fixtures, equipment or appurtenances
therein, or by the act or neglect of any other person or caused in any other
manner whatsoever; provided, however, that Landlord shall be liable for any such
damage caused by any negligent or intentional act or omission of Landlord or
Landlord's agents or employees.

BINDING AGREEMENT. All rights and liabilities herein given to or imposed upon
the respective parties hereto shall extend to and bind the respective heirs,
executors, administrators, legal representatives, successors and assigns of said
parties.

ASSIGNMENT AND SUBLEASE. So long as Tenant or any Related Entity (as hereafter
defined) is the Tenant, Tenant shall have the right, without the consent or
approval of Landlord, and without the sharing of any excess rents, recapture, or
any other rights or remedies of Landlord set forth herein, to: (a) assign its
interest in the Lease (i) to any corporation or other entity that is a successor
to Tenant either by merger or consolidation, or (ii) to a purchaser of all or
substantially all of Tenant's assets, or (iii) to a purchaser of all or
substantially all of Tenant's business line or company division that includes
the Premises use, or (iv) to a corporation or other entity that shall directly
or indirectly control, be under the control of, or be under common control with,
Tenant (any such entity being a "RELATED ENTITY"); (b) sublease all or any
portion of Premises to a Related Entity; or (c) allow or facilitate the
collocation of telecommunications equipment not owned by Tenant in the Premises.
For purposes hereof, "control" shall be deemed to mean the direct or indirect
ownership of more than fifty percent (50%) of the outstanding voting stock of a
corporation or other majority equity and control interest if not a corporation.
Tenant shall not assign its interest in the Lease or sublease all or any portion
of the Premises to any party that does not constitute a Related Entity without
first obtaining Landlord's written consent, which consent shall not be
unreasonably withheld, conditioned or delayed.

SUBORDINATION AND NON-DISTURBANCE. Tenant shall be obligated to subordinate its
interest under this Lease to any lien or encumbrance that may hereafter be
placed on, against or affecting the Premises only if, and on the condition that,
Landlord shall provide Tenant with a non-disturbance agreement in favor of
Tenant from the holder of such lien or encumbrance in the form of Exhibit D
attached hereto. Landlord shall, contemporaneously herewith, provide Tenant with
a non-disturbance agreement in favor of Tenant from the holder of any existing
lien or encumbrance now on, against or affecting the Premises in the form of
Exhibit D attached hereto. Landlord represents and warrants to Tenant that
___________________, a __________________, is the only holder of any existing
lien or encumbrance now on, against, or affecting the Premises.

ATTORNEYS' FEES. The prevailing party in any lawsuit between the Landlord and
Tenant shall be reimbursed by the non-prevailing party for its attorneys' fees
and costs.

CAPTIONS. The captions and headings of the paragraphs in this Lease are for
convenience only and shall not in any way limit or be deemed to construe or
interpret the terms and provisions hereof.

TIME OF ESSENCE. Time is of the essence of this Lease and of all provisions
hereof.

GOVERNING LAW. This Lease shall be construed and enforced in accordance with the
laws of the State in which the Premises is located.

ENTIRE AGREEMENT. The terms of this Lease are intended by the parties as a final
expression of their agreement with respect to such terms as are included in this
Lease and may not be contradicted by evidence of any prior or contemporaneous
agreement. The parties further intend that this Lease constitutes the complete
and exclusive statement of its terms and that no extrinsic evidence whatsoever
may be introduced in any judicial proceedings, if any, involving this Lease. The
Exhibits referred to herein and/or attached hereto are integral parts hereof and
are made a part of this Lease by reference.

BROKERS. Tenant and Landlord each represent to the other that it has dealt with
no broker in connection with this Lease, and each shall hold the other harmless
from and against any and all liability, loss, damage, expense, claim, action,
demand, suit or obligation arising out of or relating to a breach of such
representation. Landlord shall be responsible for the payment of any and all
commissions or other fees to any broker concerning this transaction and in no
event shall Tenant be responsible for any brokerage fees whatsoever.

consent shall not be unreasonably withheld, conditioned or delayed. Landlord and
Tenant agree that should any dispute arise between the parties in relation to

PARKING. Tenant shall have the right on a 24 hour, 7 day per week basis to three
(3) reserved, dedicated parking spaces at the Building marked for Tenant's use
at no additional rent, to be located within the area shown on the attached
Exhibit C (the "PARKING SPACES").

OPTIONS TO RENEW. Subject to the conditions set forth below, Tenant is granted
the option to renew this Lease for five (5) successive additional terms of five
(5) years each (the "RENEWAL TERMS"), with the first renewal period commencing
on the first day following the expiration of the original Lease Term. Each
Renewal Term shall be on the same terms, conditions, provisions and covenants as
are set forth herein except the Base Rent, which shall increase by $1.00 per
square foot at the commencement of each Renewal Term (i.e., $16.00/square foot
for first Renewal Term; $17.00/square foot for second Renewal Term;
$18.00/square foot for third Renewal Term; $19.00/square foot for fourth Renewal
Term; and $20.00/square foot for fifth Renewal Term). Base Rent shall be
inclusive of all real estate taxes and operating expenses throughout the Lease
Term, as extended or renewed. Tenant shall provide Landlord with at least six
(6) months prior written notice if Tenant desires to renew this Lease.

RIGHT OF FIRST REFUSAL, SECOND FLOOR. Landlord shall give Tenant written notice
of any bona fide offer to lease the contiguous space on the second floor of the
Building ("EXPANSION SPACE"), identifying the same and specifying the basic
terms and conditions the "OFFER NOTICE"). Tenant shall then have thirty (30)
business days after its receipt of the Offer Notice in which Tenant may give
Landlord written notice of Tenant's acceptance of up to 2,000 square feet of the
Expansion Space on the same terms and conditions of this Lease, including Rent
(the "ACCEPTANCE NOTICE"). Prior to giving the Offer Notice to Tenant, and for
fifteen (15) business days thereafter, Landlord shall not enter into any lease
of the Expansion Space with any other person or entity. If during such thirty
(30) business day period, Tenant gives Landlord an Acceptance Notice, Landlord
and Tenant shall then promptly enter into an amendment of this Lease increasing
the size of the Premises to include the Expansion Space (or the accepted portion
thereof) and increasing Tenant's Proportionate Share to reflect the rentable
square feet of the Expansion Space (or the accepted portion thereof). After
expiration of such thirty (30) business day period, if Tenant has not given
Landlord a timely Acceptance Notice, then Landlord shall be free to lease the
Expansion Space to such person or entity, unless the space is thereafter vacant
again in which case Landlord shall provide Tenant with another Offer Notice.
Tenant's leasehold improvements to the Expansion Space shall be governed by
Section 0 of this Lease.

against the personal property of Tenant whether existing under common law or by
statute of the State in which the Premises is located.

Building, and/or Real Property shall comply with all applicable Federal, state
and local laws, rules and regulations. If either Tenant's or Landlord's use,
transportation, storage or disposal of Hazardous Materials results in
contamination of the Premises, Building or Real Property, Tenant or Landlord (as
the case may be) shall notify the other party of its method, time and procedure
for any clean-up or removal of the Hazardous Materials. The party notified shall

ordinances to immediately remove the contamination, or is under an order to
proceed in a specified manner, that party shall comply with the law, regulation,

         THIS AGREEMENT dated the ___ day of ____________, 20___, between
_______________________________________________________, hereinafter called the
"MORTGAGEE", and MCI WORLDCOM NETWORK SERVICES, INC., hereinafter called the
"TENANT".

                              W I T N E S S E T H:

         WHEREAS, the Tenant has entered into a certain Lease, as may be
hereafter amended (the "LEASE"), dated ___________ _______, 200__with
_____________________________, hereinafter called the "LANDLORD", covering
premises in the Pentagon City Two building located at 601 S. 12th Street,
Arlington, Virginia (the "BUILDING").

         WHEREAS, the Mortgagee has made a mortgage loan (the "MORTGAGE") to the
Landlord; and

         WHEREAS, the Tenant desires to be assured of continued occupancy of
such premises under the terms of the Lease.

         NOW, THEREFORE, in consideration of the premises and of the sum of One
Dollar ($1.00) by each party in hand paid to the other, the receipt of which is
hereby acknowledged, it is hereby agreed as follows:

The Lease is and shall be subject and subordinate to the Mortgage insofar as it
affects the real property of which the Premises (as such term is defined by the
Lease) form a part, and to all renewals, modifications, consolidations,
replacements and extensions thereof, to the full extent of the principal sum
secured thereby and interest thereon.

So long as Tenant is not in default under any of the terms, covenants, or
conditions of the Lease beyond all applicable notice and cure periods, if the
interest of the Landlord under the Lease is acquired by Mortgagee, by reason of
exercise of the power of sale or the foreclosure of the Mortgage or other
proceedings brought to enforce the rights of the holder thereof, whether by deed
in lieu of foreclosure or by any other method, Tenant shall peaceably and
quietly have, hold, and enjoy the Premises and the appurtenant rights thereto
for the full Lease Term, including any renewals or extensions thereof. In the
event it should become necessary to foreclose the Mortgage, the Mortgagee
thereunder will not join the Tenant under said Lease in summary or foreclosure
proceedings, so long as Tenant is not in default beyond any applicable cure
periods under any of the terms, covenants, or conditions of said Lease.

In the event that the Mortgagee shall, in accordance with the foregoing, succeed
to the interest of the Landlord under such Lease, the Mortgagee agrees to be
bound to the Tenant under all of the terms, covenants and conditions of the
Lease, and the Tenant shall, from and after such event, have the same remedies
against the Mortgagee for the breach of an agreement contained in the

                                       P-1

<PAGE>

Lease that the Tenant might have had under the Lease against the Landlord if the
Mortgagee had not succeeded to the interest of the Landlord; provided, however,
that the Mortgagee shall not be:

                           (a)      liable for any act or omission of any prior
                  landlord (including the Landlord); provided that the foregoing
                  shall not limit Mortgagee's obligation to correct any
                  conditions that existed as of the date of attornment and
                  violate Mortgagee's obligations as landlord under the Lease;
                  or

                           (b)      bound by any rent or additional rent which
                  the Tenant might have paid for more than the current month to
                  any prior landlord (including the Landlord).

Mortgagee consents to the terms of the Lease and agrees that the exercise by the
Tenant of its rights under the Lease shall not constitute a default under the
Mortgage.

Mortgagee's consent shall not be required for any amendment or modification of
the Lease.

The provisions of this Agreement shall be binding upon and inure to the benefit
of the parties hereto and their respective successors and assigns.

This Agreement may not be discharged or modified orally or by any course of
conduct of the parties hereto other than by agreement in writing specifically
referring to this Agreement and signed by the party or parties to be charged
thereby.

         IN WITNESS WHEREOF, the parties hereto have executed these presents the
day and year first above written.

                                    offer has been determined by the Debtors to
                                    be the Final Auction Offer;

                           (v)      Evidence, acceptable to the Debtors, of the
                                    Competing Offeror's (A) ability to

                                    the sale and (B) future performance to
                                    counterparties under the contracts and
                                    leases proposed to be assigned, including

                                    by section 365 of the Bankruptcy Code.

                  4.       Competing offers shall be unconditional and not
                           contingent upon any event, including, without
                           limitation, any due diligence investigation, the
                           receipt of financing or the receipt of any further

                           board of directors, shareholders or otherwise. Any
                           person submitting a competing offer hereby shall be
                           deemed to have submitted to the jurisdiction of this
                           Court.

                  5.       The Debtors may, in their discretion, communicate
                           prior to the Sale Hearing with any Competing Offeror,
                           in which event, such Competing Offeror shall provide
                           to the Debtors, within one business day after the
                           Debtors' request therefor, any additional information
                           reasonably required

                           by the Debtors in connection with the Debtors'
                           evaluation of such Competing Offeror's offer.

                  6.       Prior to the Auction, the Debtors shall evaluate
                           Purchaser's offer, as embodied in the Agreement, and
                           any competing offers they have received, and after
                           consultation with the Committee, shall select the
                           offer the Debtors determine to be the highest and
                           best offer for the Assets (the "Initial Auction
                           Offer"). In considering Purchaser's Offer and
                           competing offers, the Debtors shall consider, among
                           other things, the value thereof to their estates, the
                           changes to the Agreement required by the Competing
                           Offeror, the Competing Offeror's satisfaction of any
                           governmental or regulatory requirements, and the
                           Competing Offeror's ability to finance, and timely
                           consummate, its proposed Alternative Transaction.

                  7.       The Auction shall be conducted by the Debtors or
                           their representatives on invitation to Purchaser and
                           all qualified Competing Offerors that have submitted
                           competing offers in accordance with these procedures,
                           and shall commence on [_______ __], 2003 at [__:__]
                           _.m. New York City time at the offices of the
                           Debtors' counsel, Weil, Gotshal & Manges LLP, 767
                           Fifth Avenue, New York, New York 10153.

                  8.       At the commencement of the Auction, the Debtors shall
                           announce the Initial Auction Offer. All bids at the
                           Auction shall be increased therefrom, and thereafter
                           made, in increments of no less than Two Hundred
                           Thousand Dollars ($200,000). The Purchaser may submit
                           competing offer(s) ("Purchaser Subsequent Offer")
                           without waiving its right to the Break-Up Fee (as
                           defined below) in the event an Alternative
                           Transaction is consummated with a Successful Offeror
                           (as defined below) other than Purchaser (or an
                           affiliate of Purchaser). The Purchaser may not apply
                           or credit any portion of the Break-Up Fee as a
                           component of Purchaser Subsequent Offers.

                  9.       Following the conclusion of the Auction, and after
                           consultation with the Committee's counsel and
                           financial advisor, the Debtors shall select the offer
                           that they determine to be the highest and best offer
                           for the Assets (the "Final Auction Offer") and shall
                           inform the party having submitted the Final Auction
                           Offer (the "Successful Offeror") and file with the
                           Court a notice of such selection. Within one business
                           day after the Debtors so notify the Successful
                           Offeror that its offer has been determined by the
                           Debtors to be the Final Auction Offer, the Successful
                           Offeror, whether or not such party is Purchaser,
                           shall deliver the Remaining Deposit to the Debtors.
                           At the Sale Hearing, the Court will consider the
                           Final Auction Offer for approval.

                  10.      Each Initial Deposit and Remaining Deposit shall be
                           maintained in an interest-bearing account and be
                           subject to the jurisdiction of this Court. The Full
                           Deposit shall be applied by the Debtors against the
                           purchase price to be paid by the Successful Offeror
                           at the closing of the transaction

                           approved by the Court. Promptly following such
                           closing, each Initial Deposit submitted by a party
                           other than a Successful Offeror, together with any
                           interest paid thereon, shall be returned.

                  11.      In the event the Successful Offeror fails to
                           consummate said transaction due to its breach of the
                           terms of its agreement with the Debtors, such
                           Successful Offeror's Full Deposit, together with any
                           interest paid thereon, shall be forfeited to the
                           Debtors and the Debtors may request authority to
                           consummate a transaction with the Competing Offeror
                           having submitted the next highest and best offer at
                           the final price and terms bid by such Competing
                           Offeror at the Auction (or, if such Competing Offeror
                           fails to consummate such transaction, the Debtors may
                           consummate a transaction with the next highest and
                           best Competing Offeror, and so forth, such subsequent
                           offeror(s) shall be deemed the "Successful Offeror"
                           for purposes of this Order), subject to the delivery
                           by any such Successful Offeror of the Remaining
                           Deposit within one business day after notification by
                           the Debtors.

                  12.      No offer shall be deemed accepted unless and until it
                           is approved by this Court;

and it is further
