      Section 3.1 Term of Study Period. The term "STUDY PERIOD" shall mean the
period commencing on the Effective Date and ending at 5:00 p.m. (Eastern
Standard Time) on the date that is thirty (30) days from the Effective Date (the
"STUDY PERIOD EXPIRATION DATE"). During the Study Period, and subject to the
provisions of this Article III, the Company may conduct such reasonable due
diligence activities, inspections and studies of the Property as it deems
necessary or appropriate, and may examine and investigate all facts,
circumstances and matters relating to the Property relevant to its purchase
thereof, including, without limitation, the condition of the Land and
Improvements, title, survey matters and any other matters it deems necessary or
appropriate for purposes of consummating the transaction contemplated by this
Agreement. All such due diligence activities are sometimes referred to herein as
the "DUE DILIGENCE". If, prior to the Study Period Expiration Date, the Company
has not received all of the third party reports that the Company determines are
necessary in connection with its due diligence ("THIRD PARTY REPORTS"),
including but not limited to the Commitment, Survey (as such terms are
hereinafter defined), phase I environmental assessment, appraisal, property
condition assessment/engineering report and zoning report, then the Company
shall have a one time right to extend the Study Period Expiration Date for an
additional fifteen (15) days by written notice delivered by the Company to Owner
and the Title Company on or prior to the then current Study Period Expiration
Date, provided that such notice sets forth a description of the Third Party
Reports that have not yet been received by the Company. In no event, however,
shall the Study Period Expiration Date be later than forty-five (45) days from
(and including) the Effective Date.

                                        4
<PAGE>

The Company's right, during any period for which the Study Period is so
extended, to terminate this Agreement as hereinafter provided in this Section
3.2 may only be exercised as a result of the Company's dissatisfaction (in its
sole discretion) with the Third Party Report(s) that gave rise to the need for
the extension of the Study Period Expiration Date. If on or before the Study
Period Expiration Date, the Company, in its sole and absolute discretion, shall
elect not to proceed to the Closing for any reason or for no reason, then the
Company shall have the right to terminate this Agreement by giving written
notice of termination to Owner and the Title Company on or before the Study
Period Expiration Date, as the same may have been extended, (time being of the
essence with respect to the giving of such notice), whereupon this Agreement
shall automatically terminate, the Deposit shall be returned to the Company, and
neither party shall have any further rights or obligations under this Agreement
(other than any rights and obligations which expressly are to survive a
termination of this Agreement).

      Section 3.2 Due Diligence. (a) During the Study Period, Owner shall afford
the Company and its authorized representatives access to the Property at
agreed-upon times for reasonable and customary due diligence purposes, subject
in all respects to the rights of the Tenant under the Lease. The Company shall
provide Owner or its authorized representatives with not less than one (1)
Business Days' prior written notice that the Company desires access to the
Property. Owner may have one or more representatives of Owner and/or the Tenant
accompany the Company during any such entry. The Company shall conduct the Due
Diligence in a manner which is not disruptive to the business operations
currently being conducted at the Property. Owner has delivered to the Company
legible, true, correct and complete copies of the documents and instruments
listed in Exhibit 3.2.1 attached hereto, and Owner agrees to deliver to the
Company within seven (7) days of the Effective Date legible, true, correct and
complete copies of the documents and instruments listed in Exhibit 3.2.2
attached hereto, to the extent the same (i) have not heretofore been delivered
by Owner to the Company and (ii) are in the possession of Owner or are within
the reasonable control of Owner and can be obtained by Owner without additional
cost to Owner. In addition, Owner agrees to make available to the Company any
other documents and information relating to the Property, Owner and/or the
Existing Loan reasonably requested by the Company, provided that such documents
and information are in the possession of Owner or are within the reasonable
control of Owner and can be obtained by Owner without additional cost to Owner.
During the Study Period, Owner shall also afford the Company and its authorized
representatives access to the property manager retained by Owner to manage the
Property (the "PROPERTY MANAGER") and all records and files relating to the
Property (financial and otherwise) in the possession and/or control of the
Property Manager. The Company shall provide Owner or its authorized
representatives with not less than one (1) Business Days' prior written notice
that the Company desires access to the Property Manager. At the request of the
Company, Owner agrees to use commercially reasonable efforts to convene a
face-to-face meeting between senior representatives of the Company and the
Tenant. One or more representatives of Owner may attend all such meetings.

            (b) The Company shall not conduct (or cause to be conducted) any
physically intrusive due diligence, such as sampling of soils, water or building
materials without the prior written consent of Owner, which consent shall not be
unreasonably withheld, conditioned and/or delayed. If the Company desires to
conduct (or to have conducted) any such physically intrusive due diligence, the
Company shall identify in writing with reasonable certainty what procedures the
Company desires to perform and request Owner's prior written consent with
respect thereto,

                                        5
<PAGE>

which consent shall not be unreasonably withheld, conditioned and/or delayed.
Upon receipt of Owner's written consent, the Company shall, in performing such
due diligence, comply in all material respects (and shall cause its consultants
and representatives to comply in all material respects) with the agreed-upon
procedures and with any and all laws, ordinances, rules and regulations
applicable to the Property, and the rights of the Tenant under the Lease, and
shall not engage in any activities which would violate any permits or
Environmental Laws. Upon completion of any inspection or test, the Company shall
immediately restore the Property to the condition existing immediately prior to
such inspection or test. If the Company elects to terminate this Agreement
pursuant to Section 3.1 above, then upon request of Owner, the Company shall
provide Owner with a copy of each Third Party Report requested by Owner,
provided that Owner reimburses the Company for the reasonable costs incurred by
the Company to obtain such Third Party Reports so requested by Owner.

      Section 3.3 Liability Insurance. As a condition to Owner's consenting to
the performance of the Due Diligence, in particular but without limitation to
entering upon the Property for the purpose of performing any physical
inspections and/or tests, the Company shall carry and maintain comprehensive
general liability insurance covering Owner, the Property Manager and Tenant
against claims for bodily injury or death or property damage occurring in, upon
or about the Property, in the amount of not less than Two Million ($2,000,000)
Dollars. Such insurance shall include blanket contractual liability coverage
insuring contractual liability under the indemnification set forth in Section
3.4 below (but such coverage or the amount thereof shall in no way limit such
indemnification). Prior to entering the Property to conduct the Due Diligence,
the Company shall provide Owner with a certificate of insurance evidencing that
such comprehensive general liability insurance is in effect. Owner, the Property
Manager and Tenant shall each be named as an additional named insured with
respect to such comprehensive general liability insurance. The Company shall
keep such insurance in full force and effect until the earlier of the Closing or
the termination of this Agreement.

      Section 3.4 Indemnification. The Company shall indemnify Owner, the
Property Manager and Tenant, and hold Owner, the Property Manager and Tenant,
and their respective agents, representatives and employees, and the Property
harmless from and against all losses, costs, damages, claims and liabilities
(whether arising out of injury or death to persons or damage to the Property or
otherwise), including, but not limited to, mechanic's and materialmen's liens
and attorneys' fees, arising out of or relating to the Due Diligence and/or
entry upon the Property under this Article III, except to the extent any such
loss, cost, damage, claim and/or liability is caused by the negligence or
willful misconduct of Owner, the Property Manager or Tenant or their respective
employees, agents and/or representatives. This Section 3.4 shall survive the
Closing or earlier termination of this Agreement.

      Section 3.5 Confidentiality. (a) All documents, materials, leases,
instruments, reports and written information heretofore or hereafter delivered
by Owner or the Property Manager to the Company with respect to the Property
(collectively, the "DUE DILIGENCE MATERIALS") shall be kept confidential and
shall not, without Owner's prior written consent, be disclosed by the Company,
or by its employees, agents, representatives or consultants, and shall not be
used by the Company, its employees, agents, representatives or consultants,
other than in connection with the proposed acquisition of the Property.

                                        6
<PAGE>

            (b) All copies of the Due Diligence Materials will be returned to
Owner immediately upon any termination or expiration of this Agreement for any
reason. All analyses, compilations, forecasts, studies, reports or other
documents prepared by the Company, its employees, agents, representatives or
consultants (including all Third Party Reports), will be held by the Company and
kept confidential (or at the option of the Company destroyed) if for any reason
(including the Company's election to terminate this Agreement in accordance with
Section 3.1 above) the Company does not acquire the Property.

            (c) If the Company violates any of the terms of this Section 3.5,
Owner shall have the right (in addition to any other rights or remedies
available to Owner at law), to seek injunctive relief to restrain any breach or
threatened breach by the Company of the terms of this Section 3.5. If the
Company, for any reason (including the Company's election to terminate this
Agreement in accordance with Section 3.1 above) does not acquire the Property,
then the provisions of this Section 3.5 shall survive the termination of this
Agreement.

      Section 3.6 As Is Condition of the Property. Other than the
representations and warranties of Owner specifically set forth herein, the
Company has not relied upon any oral or written information from Owner or its
employees, affiliates, agents, consultants, advisors or representatives,
including, without limitation, any appraisals, projections or evaluations of
credit quality prepared by Owner or any of its employees, affiliates, agents,
consultants, advisors or representatives. Without limiting the generality of the
foregoing, the Company acknowledges and agrees that, except as expressly set
forth herein, the Company is purchasing the Property "as is" and "where is" on
the Closing Date, and, except as expressly set forth herein, Owner is making no
representation or warranty, express or implied, and the Company has not relied
on any representation or warranty, express or implied, regarding the Property,
including, without limitation, any representation or warranty with respect to

part of any Property, or its fitness, merchantability or suitability for any use
or purpose, (c) the leases, rents, income or expenses of the Property, (d) the

industrial or other purposes. Owner is not liable or bound in any manner by any
verbal or written statements, representations, real estate brokers' "set-ups",
offering memorandum or information pertaining to any Property furnished by any
real estate broker, advisor, consultant, agent, employee, representative or
other person. The foregoing shall not be deemed to limit any of the Due
Diligence rights of the Company set forth in this Article III.

subject only to (a) those matters set forth on Exhibit 4.1 annexed hereto, (b)
any exceptions and matters that are approved, waived or deemed to have been
approved or waived by the Company, (c) such title exceptions as the Title
Company shall be willing to, at its regular rates, omit as exceptions to
coverage, and (d) the standard exceptions and provisions contained in the form
of insuring

                                        7
<PAGE>

agreement employed by Title Company (the liens, claims, encumbrances, exceptions
and matters set forth in subclauses (a) through (d) above being collectively
referred to as the "PERMITTED EXCEPTIONS").

      Section 4.2 Title Commitment; Survey. Promptly after the Effective Date
the Company shall obtain at its expense: (i) a title commitment from the Title
Company, together with legible copies of documents referred to in such
commitment (a "COMMITMENT"), for an owner's policy of title insurance covering
the Property which shall in all material respects satisfy the requirements, and
include the endorsements, set forth in Exhibit 4.2.1 attached hereto, and (ii) a
current plat of survey of the Property, including the Improvements (a "SURVEY")
prepared by a licensed surveyor, which shall be certified to the Company, the
Company's assignee (if any), and the Title Company by means of a certificate
substantially in the form of Exhibit 4.2.2 attached hereto. The Company shall
(i) instruct the Title Company to deliver copies of the Commitment (and all
title continuations thereof) to Owner and its attorneys concurrently with the
delivery of the Commitment to the Company, and (ii) instruct the surveyor
preparing the Survey to deliver a copy of the Survey to each of Owner and its
attorneys concurrently with its delivery thereof to the Company.

      Section 4.3 Permitted Exceptions. The Company shall have the right to
object, in its sole and absolute discretion, to any exceptions to title, or to
any matter shown on the Survey, which is not a Permitted Exception, by giving
written notice to Owner on or before the date that is five (5) Business Days
after the Company receives the Commitment and Survey (but in no event prior to
the expiration of the initial 30-day Study Period). In addition, the Company
shall have the right to object to any exception to title contained in any title
continuations which is not a Permitted Exception and is not otherwise set forth
in the Commitment, within five (5) Business Days after the Company receives such
title continuation (any such notice given pursuant to this Section 4.3 is herein
called a "TITLE OBJECTION NOTICE"). Any title exception set forth in the
Commitment, on the Survey or in a title continuation notice, which is not timely
objected to by delivery of a Title Objection Notice shall be deemed to be a
Permitted Exception, provided, however, that in no event shall any title defect
required to be discharged by Owner pursuant to Section 4.6 below or any
Violation required to be cured by Owner pursuant to Section 4.8 below, be for
any purpose considered a "Permitted Exception", nor shall the Company have any
obligation to object to any title defect required to be discharged by Owner
pursuant to Section 4.6 below or any Violation required to be cured by Owner
pursuant to Section 4.8 below.

      Section 4.4 Owner's Rights. (a) Owner shall have the right, in its sole
discretion, upon written notice to the Company and the Title Company (the "TITLE
RESPONSE NOTICE") given within ten (10) days after Owner's receipt of any Title
Objection Notice, to elect to either (i) take such action as Owner deems
advisable to discharge those title exceptions which are not Permitted Exceptions
and are set forth in the Title Objection Notice (the "TITLE DEFECTS") or (ii)
terminate this Agreement, whereupon the Deposit (and any interest thereon) shall
be promptly refunded to the Company and thereafter neither party hereto shall
have any further obligation to the other party hereto, with the exception of
those obligations which expressly survive the termination of this Agreement. If
Owner fails timely to deliver the Title Response Notice, then Owner shall be
deemed to have elected to terminate this Agreement pursuant to clause (ii)
above. If Owner, in its Title Response Notice, elects to take action to remove,
remedy or comply with the Title Defects, Owner shall be entitled to one or more
adjournment(s) of the Closing for up to

                                        8
<PAGE>

thirty (30) days in the aggregate, to discharge the Title Defects. If Owner is
unable to remove, remedy or comply with such Title Defects at the expiration of
such adjournment, then this Agreement shall be deemed to be terminated as of the
adjourned date of Closing. Upon such termination, the Deposit (and any interest
thereon) shall be promptly refunded to the Company and neither party hereto
shall have any further obligation to the other party hereto, with the exception
of those obligations which expressly survive the termination of this Agreement.
Except as set forth in Section 4.6 hereof, nothing in this Agreement shall be
deemed to require Owner to take or bring any action or proceeding or any other
steps to remove any defect in or objection to title or to expend any moneys
therefor, nor shall the Company have any right of action against Owner, at law
or in equity, therefor.

            (b) If, at the Closing, there are any title exceptions which are not
Permitted Exceptions and which Owner is obligated by this Agreement or elects to
pay and discharge, Owner may use any portion of the Purchase Price or any other
sum to satisfy the same, provided that Owner shall have delivered to the Title
Company at the Closing instruments in recordable form sufficient to satisfy such
title exceptions of record, together with the cost of any applicable recording
or filing fees. The existence of any such liens or encumbrances shall not be
deemed objections to title if Owner shall comply with the foregoing
requirements, and so advises the Company in writing of its intent to do so.

      Section 4.5 The Company's Right to Accept Title. The Company may, upon
written notice to Owner at any time on or before the Closing Date (as the same
may have been adjourned by Owner in accordance with the provisions of Section
4.4 hereof), elect to accept such title as Owner can convey, notwithstanding the
existence of any Title Defects. In such event, (i) this Agreement shall remain
in force and effect, (ii) the parties shall proceed to Closing and (iii) unless
otherwise agreed by the Company and Owner, the Company shall not be entitled to
any abatement of the Purchase Price, any credit or allowance of any kind or any
claim or right of action against Owner for damages or otherwise by reason of the
Title Defects.

      Section 4.6 Owner's Obligations. Notwithstanding anything contained in
this Article IV to the contrary, Owner shall at or prior to Closing discharge
any Title Defects which are (i) knowingly and intentionally created by Owner
subsequent to the date hereof and (ii) liquidated in amount and may be
discharged solely by the payment of a sum of money, provided that in no event
shall Owner be required to expend in excess of One Hundred Thousand and No/100
Dollars ($100,000.00) in the aggregate to discharge any such liquidated Title
Defects and to cure Violations pursuant to Section 4.8 below.

      Section 4.7 Title Affidavits, Etc. (a) If requested by the Title Company,
Owner shall deliver (i) one or more reasonable and customary title affidavits
executed by Owner, certifying to factual matters concerning Owner or the
Property which are within the knowledge of Owner, (including, without
limitation, any reasonable and customary affidavit which may be required in
order to omit from title insurance coverage any exceptions for judgments,
bankruptcies or other returns against persons or entities, other than Owner,
whose names are the same as or similar to Owner's name), (ii) documents
evidencing Owner's payment of franchise or unincorporated business taxes, as
applicable, and (iii) any other documents reasonably requested by the Title
Company to issue the title insurance required pursuant to this Agreement.

            (b) If requested by the Title Company, the Company shall deliver (i)
one or more reasonable and customary title affidavits executed by the Company,
certifying to factual matters concerning the Company which are within the
knowledge of the Company (including without limitation any reasonable and
customary affidavit which may be required in order to omit from title insurance
coverage any exceptions for judgments, bankruptcies or other returns against
persons or entities, other than the Company, whose names are the same as or
similar to Company's name), (ii) documents evidencing Company's payment of
franchise or unincorporated business taxes, as applicable, and (iii) any other
documents reasonably requested by the Title Company to issue the title insurance
required pursuant to this Agreement.

      Section 4.8 Violations. Owner shall cure, or cause to be cured, any
Violations, whether the same have been noted or issued as of the date hereof or
are first noted or issued after the date hereof, provided that in no event shall
Owner be required to expend in excess of One Hundred Thousand and No/100 Dollars
($100,000.00) in the aggregate to cure Violations and remove Title Defects
pursuant to Section 4.6 above. As used herein, the term "VIOLATION(S)" shall
mean any violation of any law or municipal ordinance, order or requirement noted
or issued against the Property by any federal, state or municipal department
having jurisdiction over the Property, other than any such violation that is the
responsibility of the Tenant to cure, comply with, remove or otherwise discharge
pursuant to the terms of the Lease or applicable law.

      Section 4.9 No Limitation on Due Diligence Termination Rights. Nothing set
forth in this Article IV shall limit the Company's right to terminate this
Agreement as set forth in Article III.

                                    ARTICLE V

                                       11
<PAGE>

or cure period, would constitute a default or event of acceleration of any of
the Existing Loan Documents.

                  (iii) Except as expressly set forth in the Existing Loan
Documents, no material term, covenant or condition of the Existing Loan
Documents has been waived, modified, altered, satisfied, canceled or
subordinated in any respect or rescinded.

balance, accrued interest and any late fees or collection costs due and owing to
Existing Lender and the balance of any escrow and other accounts maintained by
or for the benefit of Existing Lender with respect to the Existing Loan are set
forth in Exhibit 5.1(iv).

                  (v) The Existing Loan is the only indebtedness of Owner
secured by the Property, and the only documents and instruments executed by
Owner in connection with the Existing Loan that encumber the Property are the
Existing Mortgage, a related assignment of leases and rents made by Owner in
favor of Lender and uniform commercial code financing statements naming Owner as
debtor and Lender as secured party.

                  (vi) Each of the Existing Loan Documents is the legal, valid
and binding obligation of Owner, enforceable in accordance with its terms,
except as such enforcement may be limited in the future by bankruptcy,
insolvency, reorganization or other similar laws affecting the enforcement of
creditors' rights generally, and by general principles of equity (regardless of
whether such enforcement is considered in a proceeding in equity or at law).

            (j) Material Change. Owner has not received written notice from any
Governmental Authority of any pending or contemplated change in any regulation,
code, ordinance or law, or private restriction applicable to the Property, or
any natural or artificial condition upon or affecting the Property, or any part
thereof, which would result in any material change in the condition of the
Property or any part thereof, or would in any way limit or impede the operation
or development of the Property.

            (k) Accuracy of Documents. Owner has previously delivered to the
Company the documents and records listed on Exhibit 3.2.1 hereto, and shall to
the extent the same are within the possession and/or reasonable control of Owner
and have not heretofore been delivered to Owner, deliver to the Company within
seven (7) days of the Effective Date, the documents and information listed in
Exhibit 3.2.2. To the extent prepared by Owner or its employees, such documents
are true, correct and complete, and accurately reflect the matters contained
therein in every material respect. To the extent such documents have not been
prepared by Owner, to Owner's Knowledge there are no facts or circumstances that
would make any of such documents or records and the matters contained therein,
inaccurate in any material respect.

            (l) Tax Matters. Owner has relied solely on its own counsel for
advice on any and all federal, state and local tax matters relating to this
Agreement and the transactions contemplated herein and has not relied on any
advice or representations of the Company, or its counsel with respect to any
federal, state and local tax matters relating to this Agreement or the
transactions contemplated herein.

<PAGE>

            (m) Warranties. Owner has not released or modified any warranties of
builders, contractors, manufacturers or other trades persons that have been
given to Owner and to Owner's Knowledge all such warranties are in full force
and effect.

            (n) Bankruptcy. Owner has not: (i) made a general assignment for the
benefit of creditors; (ii) filed any voluntary petition in bankruptcy or
suffered the filing of an involuntary petition by Owner's creditors; (iii)
suffered the appointment of a receiver to take possession of all or
substantially all of Owner's assets; (iv) suffered the attachment, or other
judicial seizure of all, or substantially all, of Owner's assets; (v) admitted
in writing its inability to pay its debts as they come due; or (vi) made an
offer of settlement, extension or compromise to its creditors generally.

            (o) Permits, Etc. To Owner's Knowledge, all permits, licenses,
authorizations and certificates of occupancy required by Governmental
Authorities for the management, occupancy, leasing and operation of the Property
are in full force and effect (it being acknowledged by the parties that Owner
does not have a copy of the certificate of occupancy for the Property, and that
Owner is relying on a letter dated April 1, 2004 from the City of Roseville,
Community Development Department to Greenwich Capital Financial Products, Inc.
(the "ZONING LETTER") which states that a certificate of occupancy was issued
for the Property; Owner has delivered a true copy of the Zoning Letter to the
Company);

            (p) Compliance with Law Under the Lease. To Owner's Knowledge, there
does not currently exist any obligation to be taken or performed by the Tenant
pursuant to the Lease that if not taken or performed, would cause the Property
to be in non-compliance with any federal, state, municipal and other
governmental laws, ordinances, requirements, rules, regulations, notices, codes
and orders, or any agreements, covenants, conditions, easements and restrictions
currently in effect and relating to the Property.

            (q) Zoning; Governmental Rules and Regulations Under the Lease and
Existing Loan Documents. To Owner's Knowledge as of the date hereof, there is no
requirement of applicable law, the Lease or Existing Loan Document that would
require Owner to sell, mortgage, pledge, hypothecate or otherwise transfer or
dispose of all or any part of the Property or any interest therein, or initiate,
consent to, approve or otherwise take any action with respect to zoning or any
other governmental rules or regulations presently applicable to all or any part
of the Property.

            (r) Not Misleading. Without limiting any of the representations and
warranties of Owner set forth in this Agreement, such representations and
warranties do not make any untrue statement of a material fact, or to Owner's
Knowledge, omit to state a material fact necessary in order to make the
statements made, in light of the circumstances under which they were made, not
misleading.

            The Company agrees that, if (i) during the Study Period, the Company
shall discover any state of facts that differs from any of the representations
set forth in Section 5.1 above or that would make such representations untrue,
or (ii) if any of the documents listed in Exhibit 3.2.1 contains any facts or
statements that differ from any of the representations set forth

                                       13

in Section 5.1 above or that would make such representations untrue, then the
Company shall promptly advise the Owner in writing of such different state of
facts.

forth below are true and correct on and as of the Effective Date:

Closing to satisfy all conditions to the Closing which are within Owner's
reasonable power to satisfy.

            (f) No Sale or Encumbrance. Owner shall not sell, mortgage, pledge,
hypothecate or otherwise transfer or dispose of all or any part of the Property
or any interest therein, or initiate, consent to, approve or otherwise take any

improvements and/or action to be taken, completed and fully paid for by Owner,

      Section 7.1 Assumption of Existing Loan. The Company recognizes and agrees
that, in connection with the Existing Loan, the Property presently is encumbered
by the Existing Mortgage. The Loan is evidenced by that certain promissory note
dated as of May 12, 2004 in the stated principal amount of $20,860,000 (the

Closing, the Company shall assume Owner's obligations under the Existing Note
and all of the other Existing Loan Documents and accept title to the Property
subject to the Existing Mortgage. It shall be a condition to the Owner's and the
Company's obligations hereunder that at Closing the Existing Lender shall
release Owner, as well as any guarantors and other obligated parties under the
Existing Loan Documents from all obligations under the Existing Loan Documents
(and any related guarantees or letters of credit), including, without
limitation, any obligation to make payments of principal and interest under the
Existing Note (the foregoing assumption of the Existing Loan and the release of
Owner and all guarantors thereunder being herein called the "LOAN ASSUMPTION AND
RELEASE"). The Company shall, within three (3) Business Days of the Effective
Date, submit to the Lender a completed application for the Loan Assumption and
Release (the "APPLICATION"). The Company and Owner each agree to use
commercially reasonable diligent efforts to cause the Loan Assumption and
Release to be consummated in the most timely and efficient manner. The Company
shall pay all fees and expenses imposed or charged by the Lender and its counsel
in connection with the Loan Assumption and Release, including, without
limitation, all servicing fees and charges, transfer fees, assumption fees,
title fees and endorsement fees and this obligation to pay fees and expenses
shall survive the Closing or any earlier termination of this Agreement. The
Company and Owner shall each pay their own legal fees and costs and expenses in
connection with the Loan Assumption and Release. In connection with the Loan
Assumption and Release, the Company shall form a subsidiary entity to take title
to the Property, which subsidiary entity shall be a bankruptcy remote single
purpose entity which satisfies the requirements of the Existing Loan Documents
and of the Existing Lender.

Company without the Company's prior written consent.

            (b) If any condition described in Section 9.2 is not satisfied as of

                           PRORATIONS AND ADJUSTMENTS

      Section 12.1 Prorations and Adjustments. (a) Rents. All rents payable by
the Tenant to Owner under the Lease shall, at the Closing, be apportioned
between Owner and the Company as of 11:59 p.m. of the day immediately prior to
the Closing Date.

            (b) Existing Loan Payments. Any current payments of principal and
interest, and any reserve amounts, due pursuant to the Existing Loan for the
month in which the Closing occurs shall at the Closing, be apportioned between
Owner and the Company as of 11:59 p.m. of the day immediately prior to the
Closing Date. All other payment items with respect to the Existing Loan shall be
brought current at the Closing by Owner.

            (c) Reserves, etc. The Company shall reimburse Owner for all
reserves, impounds and other sums assigned to the Company that are then on
deposit with the Lender and required to be maintained by the borrower under the
Existing Loan Documents in connection with the Existing Loan.

            (d) Other Items. All other items which are customarily apportioned
in connection with the purchase and sale of real property similar to the
Property in the jurisdiction in which the Property is located shall, at the
Closing, be apportioned between the Owner and the Company as of 11:59 p.m. of
day immediately prior to the Closing; provided, however, that in no event shall
any item of expense be apportioned hereunder if, and to the extent that, such
expense item is the obligation of the Tenant under the Lease (it being agreed
that each of Owner and the Company shall look solely to the Tenant for the
payment of such expense during their respective periods of ownership).

            (e) Tax Refunds. Notwithstanding the foregoing, any refunds of real
property taxes for tax years beginning prior to the Closing Date shall belong to
Tenant, and if paid to the Company shall be promptly refunded by the Company to
Tenant in accordance with the provisions of the Lease.

            (f) Rent Step Up Adjustment. If the Closing shall occur prior to
January 1, 2006, then at Closing the Company shall receive a credit against the
Cash Balance in an amount equal to the product of (i) two hundred and forty six
and 26/100 dollars ($246.26) times (ii) the number of days in the period
commencing on (and including) the Closing Date and ending on December 31, 2005.

            (g) Overage Rent.

                  (i) All reimbursements or payments in respect of operating
expenses, real estate taxes, and other charges (collectively, "OVERAGE RENT")
paid pursuant to the Lease for the accounting period in which the Closing occurs
shall when received be apportioned between Owner and the Company as of 11:59
P.M. of the day preceding the Closing Date. Owner shall be entitled to receive
the proportion of such Overage Rent (less any reasonable costs and expenses
incurred in the collection of such Overage Rent), that the portion of such
accounting period prior to the Closing Date bears to the entire such accounting
period. The Company shall

                                       22
<PAGE>

be entitled to receive the proportion of such Overage Rent (less any reasonable
costs and expenses incurred in the collection of such Overage Rent) that the
portion of such accounting period from and after the Closing Date bears to the
entire such accounting period. If, prior to the Closing, Owner shall receive any
installments of Overage Rent attributable to Overage Rent for periods from and
after the Closing Date, such sum shall be credited against the Cash Balance
payable by the Company at the Closing. As to Overage Rent in respect of an
accounting period that shall have expired prior to the Closing, but which shall
be paid after the Closing, the Company agrees that it will pay the entire amount
over to Owner upon receipt thereof, less the Company's reasonable costs of
collection reasonably allocable thereto. The Company agrees that it shall
promptly render bills for any Overage Rent in respect of an accounting period
that shall have expired prior to Closing but which shall be payable after the
Closing, and use commercially reasonable efforts in the collection of Overage
Rent, provided, however, that the Company shall have no obligation to commence
any legal actions or proceedings to collect any such Overage Rent. Owner shall
furnish to the Company all information relating to the period prior to the
Closing that is reasonably necessary for the billing of such Overage Rent. The
Company shall deliver to Owner, concurrently with the delivery to Tenant, copies
of all statements relating to Overage Rent for periods prior to the Closing.

                  (ii) To the extent that any portion of the Overage Rent is
required to be paid monthly or on another periodic basis, by Tenant on account
of estimated amounts for the current period, and at the end of each calendar
year (or, if applicable, at the end of each lease year or tax year, as the case
may be), such estimated amounts are to be recalculated based upon the actual
expenses, taxes and other relevant factors for that calendar (lease or tax)
year, with the appropriate adjustments being made with Tenant, then such portion
of the Overage Rent paid shall be prorated between Owner and the Company at the
Closing, based on such estimated payments (i.e., with Owner entitled to retain
all monthly and other periodic installments of such amounts paid with respect to
periods prior to the calendar month or other relevant period in which the
Closing Date occurs, Owner to pay to the Company at the Closing all monthly or
other relevant period installments of such amounts paid with respect to periods
following the calendar month or other relevant period in which the Closing
occurs and Owner and the Company shall apportion all monthly installments of
such amounts with respect to the calendar month in which the Closing occurs) and
at the time(s) of final calculation and collection from (or refund to) Tenant of
the amounts in reconciliation of actual Overage Rent for a period for which
estimated amounts have been prorated, there shall be a reproration between Owner
and the Company, with the net credit resulting from such reproration being
payable to the appropriate party (i.e., to Owner if the recalculated amounts
exceed the estimated amounts and to the Company if the recalculated amounts are
less than the estimated amounts).

      Section 12.2 Costs and Expenses. Except as otherwise provided in this
Agreement, the Company shall be solely responsible for the following: (a) all
costs of preparation of the Survey for the Property; (b) all costs of conducting
all environmental tests and other Due Diligence of and with respect to the
Property; (c) all costs associated with the issuance to the Company of the new
owner's policy of title insurance and all endorsements thereto, including
without limitation, the premium for such policy, and the cost and expense of
title examination, title clearance and issuance of the Commitment; and (d) all
costs and fees in connection with the assumption of the Existing Loan. Owner
shall pay all costs associated with: (i) any costs of state, county, city,
local, municipal and township recording, transfer and similar taxes and
impositions with respect

                                       23
<PAGE>

to the conveyance of the Property; (ii) repaying any indebtedness secured by the
Property (other than the Existing Loan); and (iii) any gains taxes, income taxes
or similar taxes owing as a result of the transactions contemplated hereby. The
Company and Owner shall share equally escrow fees and other closing costs. The
Company and Owner shall each pay their respective legal fees and expenses
incurred in connection with the negotiation of this Agreement and all related
documents, and in addressing each such party's tax and securities issues.

                                  ARTICLE XIII
                                     DEFAULT

      Section 13.1 Default By The Company. If (i) any of the representations and
warranties made by the Company in this Agreement (as updated by the Company's
Representation Certificate) are inaccurate or incorrect in any material respect
on the date made or deemed made, or (ii) if the Company fails to perform its
covenants, obligations or agreements under this Agreement and such failure is
not cured on or before the earlier of ten (10) days after written notice by
Owner to Company or the Closing Date, or (iii) the purchaser under the Other
Contract (the "OTHER PURCHASER") fails to perform its covenants, obligations or
agreements under the Other Contract and the seller under the Other Contract (the
`OTHER SELLER") terminates the Other Contract as a result of such failure, then
in any of such events, Owner's sole and exclusive remedy shall be the right to
cancel and terminate this Agreement and receive and retain the Deposit
(provided, however, that if the Company is then obligated to post the Additional
Deposit but has not done so, then Owner shall have a right to receive the
Initial Deposit and shall have a post termination damage claim against the
Company for the Additional Deposit and all expenses incurred by owner in
collecting same, including reasonable attorneys' fees). Upon such termination,
each party shall be released from all duties or obligations contained herein
except as may otherwise be expressly set forth in this Agreement as surviving a
termination of this Agreement, and the Title Company shall immediately pay the
Deposit to Owner as liquidated damages as the sole and exclusive remedy of
Owner, it being understood and agreed that Owner is hereby releasing and/or
waiving any right it might have to either specifically enforce this Agreement or
to sue for damages (other than to collect the Additional Deposit, as aforesaid,
if the same had not been delivered to the Title Company when due). Owner has
agreed to this liquidated damage provision because of the difficulty of
ascertaining Owner's actual damages given the uncertainties of the real estate
market, fluctuating property values and differences of opinion with respect to
such matters.

      Section 13.2 Default By Owner. If (i) any of the representations and
warranties made by Owner in this Agreement (as updated by Owner's Representation
Certificate) are inaccurate or incorrect in any material respect on the date
made or deemed made, or (ii) if Owner fails to perform its covenants,
obligations or agreements under this Agreement and such failure is not cured on
or before the earlier of ten (10) days after written notice by the Company to
Owner or the Closing Date, or (iii) the Other Seller fails to perform its
covenants, obligations or agreements under the Other Contract and the Other
Purchaser terminates the Other Contract as a result of such failure, then the
Company shall have the right, at its sole option, to: (a) terminate this
Agreement, whereupon the Deposit shall be returned to the Company and neither
party shall have any further right or liability to the other under this
Agreement except as may be otherwise expressly set forth in this Agreement; (b)
waive the default, misrepresentation or failure to

                                       24
<PAGE>

perform and proceed with the Closing without any adjustment or reduction in the
Purchase Price; or (c) receive the Deposit from the Title Company and pursue an
action for specific performance.

                                   ARTICLE XIV
                COORDINATION BETWEEN AGREEMENT AND OTHER CONTRACT

      Section 14.1 Coordination of the Sale of the Property and the Other
Property. Owner and the Company acknowledge and agree that (i) the Property and
the Other Property are intended to be sold together as part of a single
integrated transaction, (ii) as a matter of convenience only, the parties have
agreed sell the Property and the Other Property pursuant to the terms of two
separate agreements (consisting of this Agreement and the Other Contract),
rather than pursuant to a single agreement, and (iii) cross defaulting this
Agreement and the Other Contract pursuant to Sections 13.1 and 13.2 is intended
to further the intent of the parties to consummate the sale of the Property and
the Other Property as a single integrated transaction. If the Other Contract is
terminated by the Other Seller or Other Purchaser thereunder for any reason
pursuant to the terms of the Other Contract (including, without limitation, if
the Other Purchaser terminates the Other Contract prior to the end of the due
diligence period under the Other Contract pursuant to Article III of the Other
Contract), then (i) this Agreement shall automatically terminate on the date on
which such Other Contract is so terminated, (ii) if, as a result of such
termination of such Other Contract, the deposit thereunder is payable to the
Other Seller, then the Deposit (and all interest accrued thereon) shall be paid
to Owner, (iii) if, as a result of such termination of the Other Contract, the
deposit thereunder is payable to the Other Purchaser, then the Deposit (and all
interest accrued thereon) shall be paid to the Company and (iv) thereafter
neither Owner nor the Company shall any further rights or obligations hereunder,
other than those which expressly survive the termination of this Agreement.

      Section 14.2 Coordination of Closing Dates for the Sale of the Property
and the Other Property. Owner and the Company acknowledge that the intent of the
parties is that the Closing under this Agreement, and the closing under the
Other Contract, are all to occur simultaneously. If, as of any date, the then
current scheduled closing date under the Other Contract is, for any reason,
later than the then current scheduled Closing Date under this Agreement, then
and in such event, the scheduled Closing Date under this Agreement shall
automatically be adjourned to (and shall be) the then current scheduled closing
date under the Other Contract. In furtherance of the foregoing, if the Other
Seller or the Other Purchaser has any right to adjourn the closing date under
the Other Contract and exercises such right, then the scheduled Closing Date
under this Agreement shall automatically be extended to the scheduled closing
date under the Other Contract.

      Section 15.1 Casualty. (a) If, between the date hereof and the Closing,
there shall occur a fire or other casualty affecting the Improvements which is
not a Major Casualty, then the Company shall have no right to terminate this
Agreement and shall purchase the Property in its damaged condition without
reduction of or offset against the Purchase Price or any other claim against

proceeds

                                       25

payable to Owner as a result of such fire or other casualty (inclusive of any
rental interruption proceeds payable with respect to any period from and after
the Closing); provided, however, that Owner shall be entitled to retain (to the
extent theretofore paid to Owner), and shall not be obligated to assign the
right to receive (to the extent not theretofore paid to Owner), an amount of
such insurance proceeds equal to Owner's reasonable expenses, if any, incurred
in collecting such proceeds and repairing the damage caused by fire or other
casualty. For purposes hereof, a "MAJOR CASUALTY" means a fire in or other
casualty to the Improvements which causes damage or injury that the repair or
replacement cost of which would exceed Five Hundred Thousand and No/100 Dollars
($500,000.00), as determined by the professional retained by the Company to
perform a structural and/or physical inspection of the Property in connection
with the Company's acquisition of the Property pursuant to this Agreement.

            (b) If, between the date hereof and the Closing, there shall occur a
fire or other casualty affecting the Improvements which is a Major Casualty,
then the Company shall have the option, to be exercised by notice given to Owner
within ten (10) days after the Company has notice of such fir or other casualty,
to terminate this Agreement. If the Company shall so elect to terminate this
Agreement, then (i) the Company shall be entitled to the return of the Deposit
(and any interest thereon) and (ii) neither party hereto shall have any further
obligations or liabilities to the other with respect to the Property (or under
this Agreement), except for those which expressly survive the termination of
this Agreement. If the Company shall not elect to terminate this Agreement as
provided in this subsection (b), then this Agreement shall remain in full force
and effect with respect and the provisions of Section 15.1(a) above shall apply
to such damage and any insurance proceeds payable in connection therewith.

            (c) Subject to the provisions of Section 15.1(a) and the applicable
provisions of the Lease, Owner shall not have any obligation to repair any
damage or destruction to the Improvements

      Section 15.2 Condemnation or Taking. If, prior to the Closing, the
Property or any part thereof shall be condemned or taken and such condemnation
or taking materially interferes with the existing business use of the Property,
the Company may (a) terminate this Agreement, or (b) complete the transactions
contemplated by this Agreement notwithstanding such condemnation. If the Company
elects to complete the transactions contemplated hereby, the Company shall be
entitled to receive the condemnation proceeds and Owner shall, at the Closing
and thereafter, execute and deliver to the Company all required assignments of
claims and other similar items. If the Company elects to terminate this
Agreement, then upon written notice to Owner and without further action of the
parties, this Agreement shall become null and void and no party shall have any
rights or obligations under this Agreement.

by Owner pursuant to separate written agreements, and shall be paid by Owner, it
being agreed that the Company shall have no liability for any commissions, fees
payments or other sums payable to the Brokers or either of them. Each party

against any cost, expense, claim, loss, liability or damages, including
reasonable attorneys' fees and court costs, resulting from a breach of the
foregoing representation and warranty. The terms and provisions of this Section
16.1 shall survive the Closing or any earlier termination of this Agreement.

<PAGE>

to close the transfer of the Property as an exchange, then (i) Owner, at its
sole option, may delegate its obligations to transfer the Property under this
Agreement, and may assign its rights to receive the Purchase Price from the
Company, to a deferred exchange intermediary (an "INTERMEDIARY") or to an
exchange accommodation titleholder, as the case may be; (ii) such delegation and
assignment shall in no way reduce, modify or otherwise affect the obligations of
Owner pursuant to this Agreement; (iii) Owner shall remain fully liable for its
obligations under this Agreement as if such delegation and assignment shall not
have taken place; (iv) Intermediary or exchange accommodation titleholder, as
the case may be, shall have no liability to the Company; and (v) the closing of

may be.

provisions hereof are solely for the benefit of Owner and the Company and their

void, illegal or unenforceable in any respect, the remainder of this Agreement
shall be construed as if such unlawful, void, illegal or unenforceable provision

parties hereto under the remainder of this Agreement shall continue in full

dated as of November __, 2005 (the "CONTRACT"), between Owner and the Company.
The defined terms used in this Agreement shall have the meanings set forth in
the Contract.

      The Company and Owner have agreed to select Escrow Agent to serve as

            2. Escrow Agent acknowledges receipt of the Deposit and agrees to

                 [TITLE INSURANCE REQUIREMENTS AND ENDORSEMENTS]

      This Memorandum will provide you with a checklist of standard title
insurance requirements for projects being acquired by Gladstone Commercial
Corporation, or an affiliated company ("GCC"). Additional or different
requirements may be specified for your particular transaction.

      1. GENERAL:

            (a) The maximum single risk assumed by any single title insurer may
not exceed 25% of that company's capital, surplus and statutory reserves. Excess
amounts may be covered by appropriate reinsurance arrangements with other
acceptable title insurance companies.

            (b) The title insurance policy must be written by an insurer that
has an acceptable rating from at least one of the following independent rating
agencies:

            -     a "Financial Stability Rating" of "S" (Substantial) or better
                  or a "Statutory Accounting Rating" of "C" (Average) or better
                  from Demotech, Inc.;

            -     a "BBB" or better rating from Duff and Phelps Credit Rating
                  Company;

            -     a "C" or better rating from LACE Financial Corporation;

            -     a "Baa" or better rating from Moody's Investors Service; or

            -     a "BBB" or better rating from Standard and Poor's, Inc.

            (c) Each title insurance policy must be written by an insurer
authorized to do business in the jurisdiction where the property is located.

            (d) Subject to the satisfaction of other requirements set forth
herein, GCC will accept the standard 1992 ALTA form of loan title insurance
policy or the 1990, 1987 or 1970 (amended October 17, 1970, and October 17,
1984) form of owner's policies. GCC must receive and approve a commitment and a
pro forma owner's title insurance policy. Copies of all documents and/or surveys
referred to in the legal description or in the exceptions in Schedule B-I must
be submitted with the commitment. The title insurance company must remove (by
endorsement or written waiver) any creditors' rights exception or exclusion.

            (e) If the 1990 or 1987 ALTA form of policy or a policy containing
similar arbitration provisions is used, the title insurance company must agree
that the compulsory arbitration provisions of the policy do not apply for any
claims by or on behalf of the insured.

            (f) The policy must include an Environmental Protection Lien
Endorsement (ALTA Form 8.1). Subparagraph (b) of ALTA Form 8.1 may take
exception for an entire state statute that provides for environmental protection
liens that could take priority, only if specific sections or subsections are
referenced. A reference solely to a general statute is acceptable only if
approved in writing by GCC prior to closing. If no such statutes exist, "None"
should be entered in the space below subparagraph (b).

<PAGE>

            (g) The policy must include a Comprehensive Endorsement (ALTA Form
9).

      2. SCHEDULE A - DESCRIPTION:

            (a) The amount of the title insurance policy must equal at least the
original purchase price of the property.

08843672/50067-02 entered into January 14, 1994 (Contract) by and between the United States
Enrichment Corporation (USEC), Executive Agent of the United States of America, and Techsnabexport
Co. Ltd. (TENEX), Executive Agent of the Ministry of Atomic Energy (MINATOM), Executive Agent of
the Russian Federation. Capitalized terms used but not defined herein shall have the meaning
ascribed to such terms in the Contract.

     WHEREAS, the parties desire to amend the Contract to reflect changes (i) in the account number
for the remittance of payments to TENEX under the Contract and (ii) in TENEX’s name.

     NOW, THEREFORE, USEC and TENEX agree as follows:

     SECTION 1. The Contract is hereby amended as follows:

     (a) In Part I, Section G.04, the first sentence of the third paragraph is amended to read as
follows:

“Until otherwise agreed upon by the parties, all payments to TENEX shall be made to
the following account: Techsnabexport Co., Ltd., Account No. 40702840400000000010,
Conversbank, Moscow, Russia, through the account of Conversbank, Account No.
04-094-462 in Bankers Trust Company, New York, New York, ABA No. 021001033.”.

     (b) References to Techsnabexport Co., Ltd. shall be considered references to OA
Techsnabexport. This change reflects only a more precise translation of TENEX’s name and no change
to the legal entity that is TENEX.

     SECTION 2. Except as amended hereby, the Contract shall remain unchanged and in full force and
effect. In the event that any conflict arises between this Amendment and the Contract, TENEX and
USEC shall resolve such conflict consistent with the purpose of this Amendment as set forth in the
recitals herein.

     SECTION 3. This Amendment may be executed in two or more counterparts, each of which shall
constitute an original, but all of which, when taken together, shall constitute one and the same
instrument.

     IN WITNESS WHEREOF, the Parties hereto have executed this Amendment as of the date first
written above.
