<PAGE>

                             CONTRIBUTION AGREEMENT

         THIS CONTRIBUTION AGREEMENT (this "Agreement") is made as of this 7th
day of January, 2005 by and between Carr Capital Corporation, a District of
Columbia corporation ("Contributor"); and Columbia Equity, LP, a Virginia
limited partnership ("Acquirer").

                                    RECITALS

         A.       Contributor intends to sponsor a publicly-owned real estate
investment trust (the "REIT"), which REIT will own property and membership
interests in entities with direct or indirect ownership over various real
properties and improvements located thereon (the "Properties"), contributed by
and purchased from Contributor's affiliates and other entities in exchange for
partnership units (the "Units") in Acquirer.

         B.       Contributor desires to contribute all of its right, title and
interest in and to any asset management agreements (the "Asset Management
Agreements") related to the Properties or other real properties entered into by
Contributor during the period between the date first written above and the
Closing Date (as defined below) to Acquirer, on the terms and conditions
hereinafter set forth.

         C.       Acquirer desires to acquire the Asset Management Agreements
from Contributor, on the terms and conditions hereinafter set forth.

                                    AGREEMENT

         NOW, THEREFORE, for and in consideration of the mutual covenants herein
contained, the parties hereto agree as follows:

                                   ARTICLE I
                                THE CONTRIBUTION

         1.1      Contribution. Contributor agrees to contribute, transfer,
assign and convey all of its right, title and interest in and to the Asset
Management Agreements to Acquirer, and Acquirer agrees to acquire and assume the
Asset Management Agreements pursuant to the terms and conditions set forth in
this Agreement. The Asset Management Agreements shall be transferred to Acquirer
free and clear of all liens, encumbrances, security interests, prior assignments
or conveyances, conditions, restrictions, voting agreements, claims, and any
other matters affecting title thereto.

         1.2      Consideration. The total consideration (the "Consideration")
for which Contributor agrees to contribute and assign the Asset Management
Agreements to Acquirer, and which Acquirer agrees to pay or deliver to
Contributor, subject to the terms of this Agreement, shall be the issuance to
Contributor of a number of Units equal to (a) Five (5) times the projected
aggregate asset management fees payable to Acquirer under the Asset Management
Agreements for the twelve calendar months immediately following the Closing
Date, (b) divided by the price per share at which the common stock, $.01 par
value per share, (the "Common Stock") of the REIT, is offered to the public in
the underwritten initial public offering of the Common Stock (the "IPO"). On the
Closing Date (as defined below), the Units shall be issued to Contributor.

                                     - 1 -
<PAGE>

Upon the request of Contributor, Acquirer shall issue certificates reflecting
Contributor's ownership of Units. The certificates evidencing the Units will
bear appropriate legends indicating (i) that the Units have not been registered
under the Securities Act of 1933, as amended ("Securities Act"), and (ii) that
Acquirer's Amended and Restated Agreement of Limited Partnership (the
"Partnership Agreement") restricts the transfer of the Units. Upon receipt of
the Units and execution and delivery of the Partnership Agreement, Contributor
shall become a limited partner of Acquirer.

         1.3      Redemption Rights for Units. Each Unit shall be redeemable, at
the option of the holder, in accordance with, but subject to the restrictions
contained in, the Partnership Agreement; provided, however, that such redemption
option may not be exercised prior to the first anniversary of the Closing Date.

         1.4      Tax Consequences to Contributor. Notwithstanding anything to
the contrary contained in this Agreement, including without limitation the use
of words and phrases such as "sell," "sale," purchase," and "pay," the parties
hereto acknowledge and agree that it is their intent that the transaction
contemplated hereby be treated for federal income tax purposes as the
contribution of the Asset Management Agreements by Contributor to Acquirer in
exchange for Units pursuant to Section 721 of the Internal Revenue Code of 1986,
as amended (the "Code"), and not as a transaction in which Contributor is acting
other than in its capacity as a prospective partner of Acquirer.

                                   ARTICLE II
                          REPRESENTATIONS AND COVENANTS

         2.1      Representations by Acquirer. Acquirer hereby represents and
warrants unto Contributor that the following statements are true, correct, and

                  (a)      Organization and Power. Acquirer is duly organized
and validly existing, under the laws of the Commonwealth of Virginia, and has
full right, power, and authority to enter into this Agreement and to perform all

Agreement and the performance by Acquirer of its obligations under this
Agreement have been duly authorized by all requisite action of Acquirer and

individuals or entities in order to constitute this Agreement as a binding and
enforceable obligation of Acquirer.

                  (b)      Noncontravention. Neither the entry into nor the
performance of, or compliance with, this Agreement by Acquirer has resulted, or
will result, in any violation of, or default under, or result in the
acceleration of, any obligation under the Partnership Agreement, or any
mortgage, indenture, lien agreement, note, contract, permit, judgment, decree,
order, restrictive covenant, statute, rule, or regulation applicable to
Acquirer.

                  (c)      Litigation. There is no action, suit, or proceeding,

similar rights, and will be fully paid and nonassessable, without any obligation
to restore capital except as required by the Virginia Revised Uniform Limited
Partnership Act (the "Limited Partnership Act"). Upon execution and delivery of
the Partnership Agreement by Contributor, Contributor shall be admitted as a
limited partner of Acquirer as of the Closing Date and shall be entitled to all
of the rights and protections of a limited partner under the Limited Partnership
Act and the provisions of the Partnership Agreement, with the same rights,
preferences, and privileges as all other limited partners on a pari passu basis.

                  (e)      Consents. Each consent, approval, authorization,

                  (g)      Brokerage Commission. Acquirer has not engaged the
services of, nor has it or will it or Contributor become liable to, any real
estate agent, broker, finder or any other person or entity for any brokerage or
finder's fee, commission or other amount with respect to the transactions
described herein on account of any action by Acquirer. Acquirer hereby agrees to
indemnify and hold Contributor and its employees, directors, members, partners,
affiliates and agents harmless against any claims, liabilities, damages or
expenses arising out of a breach of the foregoing. This indemnification shall

Agreement and the performance by Contributor of its obligations hereunder have
been duly authorized by all requisite action of Contributor and require no
further action or approval of Contributor's board of directors or shareholders
or of any other individuals or entities in order to constitute this Agreement as

                  (b)      Noncontravention. Neither the entry into nor the

                  (f)      Securities Law Matters. (i) In acquiring the Units
and engaging in this transaction, neither Contributor nor any member or
shareholder thereof is relying upon any representations made to it by Acquirer,
or any of its partners, officers, employees, or agents that are not contained
herein. Contributor is aware of and understands the risks involved in investing
in the Units and in the Common Stock issuable upon redemption of such Units.
Contributor has had an opportunity to ask questions of, and to receive answers
from, Acquirer and the REIT or a person or persons authorized to act on their
behalf, concerning the terms and conditions of an investment in the Units and
the financial condition, affairs, and business of Acquirer and the

                                     - 4 -
<PAGE>

REIT. Contributor confirms that all documents, records, and information
pertaining to its investment in Acquirer that have been requested by it, have
been made available or delivered to Contributor prior to the date hereof.

                           (ii)     Contributor  understands that neither the
Units nor the Common Stock issuable upon redemption of the Units have been
registered under the Securities Act or any state securities acts and are instead
being offered and sold in reliance on an exemption from such registration
requirements. The Units issuable to Contributor are being acquired solely for
its own account, for investment, and are not being acquired with a view to, or
for resale in connection with, any distribution, subdivision, or
fractionalization thereof, in violation of such laws, and Contributor does not
have any present intention to enter into any contract, undertaking, agreement,
or arrangement with respect to any such resale. Contributor understands that any
certificates representing the Units will contain appropriate legends reflecting
the requirement that the Units not be resold by Contributor without registration
under such laws or the availability of an exemption from such registration.

                  (g)      Accredited Investors. Contributor is an accredited
investor as that term is defined in Rule 501 of Regulation D under the
Securities Act of 1933, as amended.

                  (h)      Tax Matters. Contributor represents and warrants
that it has obtained from its own counsel advice regarding the tax consequences
of (i) the transfer of the Asset Management Agreements to Acquirer and the
receipt of Units as consideration therefor, (ii) Contributor's admission as a
partner of Acquirer, and (iii) any other transaction contemplated by this
Agreement. Contributor further represents and warrants that it has not relied on
Acquirer or Acquirer's representatives or counsel for such tax advice.

                  (i)      Bankruptcy with respect to Contributor. No Act of
Bankruptcy has occurred with respect to Contributor.

                  (j)      Brokerage Commission. Contributor has not engaged the
services of, nor has it or will it or Acquirer become liable to, any real estate
agent, broker, finder or any other person or entity for any brokerage or
finder's fee, commission or other amount with respect to the transactions
described herein on account of any action by Contributor. Contributor hereby
agrees to indemnify and hold Acquirer and its employees, directors, members,
partners, affiliates and agents harmless against any claims, liabilities,
damages or expenses arising out of a breach of the foregoing. This
indemnification shall survive Closing or any termination of this Agreement.

                  (k)      Default. To Contributor's actual knowledge,
Contributor is not in default under any of the Asset Management Agreements.

         2.3      Covenants of Acquirer.  Acquirer agrees as follows:

                  (a)      Further Acts. In addition to the acts, instruments
and agreements recited herein and contemplated to be performed, executed and
delivered by Acquirer and Contributor, Acquirer shall perform, execute, and
deliver or cause to be performed, executed, and delivered at the Closing or
after the Closing, any and all further acts, instruments, and agreements and

                                     - 5 -
<PAGE>

provide such further assurances as Contributor may reasonably require to
consummate the transactions contemplated hereunder.

         2.4      Covenants of Contributor.  Contributor agrees as follows:

                  (a)      Actions Regarding the Asset Management Agreements.
Except as otherwise permitted hereby, from the date hereof until the Closing
Date, Contributor shall use reasonable commercial efforts not to take any action
or fail to take any action within Contributor's control the result of which
would (1) have a material adverse effect on the Asset Management Agreements,
Contributor's ability to contribute, transfer, assign and convey the Asset
Management Agreements to Acquirer or Acquirer's ability to assume and continue
to perform Contributor's obligations under the Asset Management Agreements after
the Closing Date in substantially the same manner as presently conducted or (2)
cause any of the representations and warranties contained in Section 2.2 to be
untrue as of the Closing Date.

                  (b)      Confidentiality. Contributor acknowledges that the
matters relating to the REIT, the IPO, this Agreement, and the other documents,
terms, conditions and information related thereto (collectively, the
"Information") are confidential in nature. Therefore, Contributor covenants and
agrees to keep the Information confidential and will not (except as required by
applicable law, regulation or legal process, and only after compliance with the
provisions of this Section 2.4) prior to the IPO, without Acquirer's prior
written consent, disclose any Information in any manner whatsoever; provided,
however, that the Information may be revealed only to Contributor's employees,
legal counsel and financial advisors, each of whom shall be informed of the
confidential nature of the Information. In the event that Contributor or its key
employees, legal counsel or financial advisors (collectively, the "Information
Group") are requested pursuant to, or required by, applicable law, regulation or
legal process to disclose any of the Information, the applicable member of the
Information Group will notify Acquirer promptly so that it may seek a protective
order or other appropriate remedy or, in its sole discretion, waive compliance
with the terms of this Section 2.4. Contributor acknowledges that remedies at
law may be inadequate to protect Acquirer or the REIT against any actual or
threatened breach of this Section 2.4, and, without prejudice to any other
rights and remedies otherwise available, Contributor agrees to the granting of
injunctive relief in favor of the REIT and/or Acquirer without proof of actual
damages. Notwithstanding any other express or implied agreement to the contrary,
the parties agree and acknowledge that each of them and each of their employees,
representatives, and other agents may disclose to any and all persons, without
limitation of any kind, the tax treatment and tax structure of the transaction
and all materials of any kind (including opinions or other tax analyses) that
are provided to any of them relating to such tax treatment and tax structure,
except to the extent that confidentiality is reasonably necessary to comply with
U.S. federal or state securities laws. For purposes of this paragraph, the terms
"tax treatment" and "tax structure" have the meanings specified in Treasury
Regulation section 1.6011-4(c).

                  (c)      Further Acts. In addition to the acts, instruments
and agreements recited herein and contemplated to be performed, executed and
delivered by Acquirer and Contributor, Contributor shall perform, execute, and
deliver or cause to be performed, executed, and delivered at the Closing or
after the Closing, any and all further acts, instruments, and agreements and

                                     - 6 -
<PAGE>

provide such further assurances as Acquirer may reasonably require to consummate
the transactions contemplated hereunder.

Shipper and Transporter hereby agree to the rate provisions set forth on the attached tariff
sheet and acknowledge that, subject to and upon approval by the Federal Energy Regulatory
Commission (“FERC”) of a filed tariff sheet reflecting such provisions, all of the rate
provisions contained therein will be applicable to the Service Agreement. If FERC approval of a
filed tariff sheet reflecting all of the provisions on the attached tariff sheet is not
obtained without condition or modification, this Agreement shall be null and void and of no
further effect and service under the Service Agreement will be provided at the maximum Recourse
Rate unless otherwise mutually agreed.

If the foregoing accurately sets forth your understanding of the matters covered herein, please
so specify in the space provided below by having a duly authorized representative sign in the
space provided below and returning an original signed copy to the undersigned.

	 	 	 
	

	 	Sincerely,

	1/  	This negotiated rate agreement does not deviate in any material respect from the Form of Service Agreement contained in Transporter’s Tariff.

	 
	2/  	For the months of October through April during the term of this negotiated rate the Monthly
Demand Rate is $9.42 per Dth and the Commodity Rate is $0.05 per Dth for quantities delivered
up to the MDTQ of 25,000. For the months of May through September during the term of this
negotiated rate, the Monthly Demand Rate is $0.00 per Dth and the Commodity Rate is $0.16 per
Dth delivered; provided that, for receipts and deliveries outside the primary path, the
Commodity Rate shall be $0.21 per Dth delivered. Notwithstanding the previous two sentences,
solely for the month of February 2005, the monthly Demand Rate is $12.8626 per Dth and the
Commodity Rate is $0.05 per Dth delivered up to the maximum MDTQ of the 25,000. In addition
to these rates, Shipper shall pay all applicable charges and mandatory surcharges (such as
FERC Annual Charge Adjustment) and fuel and lost and unaccounted for gas as set forth in
Transporter’s Tariff as revised from time to time pursuant to Transporter’s Tariff. Shipper
shall not be charged for any voluntary surcharges such as GRI Rate Adjustment.

	 
	3/  	In consideration of the rates set forth above, the applicable rates for service under the
Service Agreement during the Primary Term shall remain as stated above. Therefore, pursuant
to Section 4.5 of the FT-A Rate Schedule of Transporter’s FERC Gas Tariff, the rates set
forth above shall constitute Negotiated Rates. The Negotiated Rates shall replace the
otherwise generally applicable maximum recourse rate, rate component, charge or credit in
Transporter’s FERC Gas Tariff (“Tariff Rates”), and the Tariff Rates shall not apply to or be
available to Shipper for service under the Service Agreement during the Primary Term (to the
extent that such Tariff Rates are inconsistent with the rates set forth above),
notwithstanding any adjustments to such generally applicable maximum recourse rate, rate
component, charge or credit which may become effective during the Primary Term.

	 
	4/  	If, at any time after service commences under the Service Agreement, Transporter is
collecting its effective maximum recourse rates from other Shippers subject to refund under
Section 4 of the Natural Gas Act, Transporter shall have no refund obligation to customer
even if the final maximum rate is reduced to a level below the Negotiated Rate provided
herein. Customer’s right to receive credits relating to Transporter’s penalty revenue or
other similar revenue, if any, applicable to transportation service on Transporter’s system
shall be governed by Transporter’s FERC Gas Tariff and any applicable FERC orders and/or
regulations. In the event customer releases its firm transportation rights under the Service
Agreement, Shipper shall continue to be obligated to pay Transporter for the difference, if
any, by which the Negotiated Rate herein exceeds the release rate.

	 
	5/  	The term of the negotiated rate extends from the beginning of the Gas Day on February 1, 2005,
until the end of the Gas Day on March 31, 2007.

authorizes abandonment of such service, this Agreement shall terminate on the abandonment date

continue hereunder if within the thirty day notice period satisfactory assurance of payment is
made in accord with Section 16 of Transporter’s General Terms and Conditions.

necessary regulatory approval or authorization is not so obtained or
continued. All Parties hereto shall cooperate to obtain or continue
all necessary approvals or authorizations, but no Party shall be
liable to any other Party for failure to obtain or continue such
approvals or authorizations.

11.2 Promptly following the execution of this Agreement, the Parties will file, or cause to be filed, and diligently prosecute, any
necessary applications or notices with all necessary regulatory
bodies for approval of the service provided for herein.

11.3 In the event the Parties are unable to obtain all necessary and
satisfactory regulatory approvals for service prior to the
expiration of two (2) years from the effective date hereof, then,
prior to receipt of such regulatory approvals, either Party may
terminate this Agreement by giving the other Party at least thirty
(30) days prior written notice, and the respective obligations
hereunder, except for the reimbursement of filing fees herein, shall be of no force and effect
from and after the effective date of such termination.
