                             LOT PURCHASE AGREEMENT
                                 (VILLAGE LOTS)

     THIS LOT PURCHASE AGREEMENT (this "Agreement") is made as of the Effective
Date (hereinafter defined) by and between RENAISSANCE AT WOODLANDS, LLC, a
Virginia limited liability company, hereinafter called "Seller," and
NEIGHBORHOODS I, LLC, a Virginia limited liability company, hereinafter called
"Purchaser."

                                   WITNESSETH:

     WHEREAS, Seller is the owner of certain property located in Loudoun County
(the "County"), Virginia, to be recorded among the Plat Records of Loudoun
County in the subdivision known as Woodland Village, as more fully shown and
designated for single family home construction on the attached Exhibit "A" (said
property being hereinafter referred to as the "Property"); and

     WHEREAS, Purchaser wishes to acquire the single family lots set forth on
SCHEDULE 1 attached hereto (the "Lots"), which lots will be duly and properly
subdivided and created upon the Property as shown on the attached Exhibit "A."

     NOW, THEREFORE, in consideration of the premises and of the promises
hereinafter set forth, the parties agree as follows:

     1.   Bargain and Sale.

     Seller hereby promises and agrees to sell, and Purchaser hereby promises
and agrees to purchase, the Lots in accordance with the provisions of this
Agreement.

     2.   Specific Performance.

     Purchaser acknowledges that Seller, in reliance upon Purchaser's agreements
and undertakings hereunder, has made certain financial and other commitments to
third parties. Accordingly, the parties agree that in the event of a breach by
Purchaser of its obligations hereunder, Seller shall have a right of specific
performance to require Purchaser to purchase and acquire, on the terms and
conditions hereinafter set forth, three (3) of the Lots. The foregoing equitable
remedy shall be Seller's sole remedy in the event of Purchaser's breach of its
obligations hereunder.

     3.   Purchase Price.

     The purchase price for the Lots shall be as set forth on SCHEDULE 1
attached hereto (the "Purchase Price").

     4.   Payment of Purchase Price.

     The Purchase Price for each Lot purchased hereunder shall be paid in cash,
by wire transfer, title company check, or certified funds or the equivalent at
closing thereon.

<PAGE>

     5.   Closing.

     Commencing with the first take down of lots (other than the Model Lot)
under the Lot Purchase Agreement for the Executive Lots, Purchaser agrees to
take down eight (8) Lots per "Quarter" (as defined below). If in any Quarter
purchases exceed the then required takedown schedule, Purchaser shall be given a
credit for such Lots against the next required takedown schedule. Purchaser
reserves the right to accelerate the takedown schedule, subject to the
availability of Lots. The sequence of Lot takedowns shall be agreed upon by
Seller and Purchaser. Modifications to the sequence and/or the takedown schedule
must be agreed upon by both Seller and Purchaser. Notwithstanding the foregoing
and after the 17th Lot has been purchased, Purchaser shall have the right,
exercisable in Purchaser's sole discretion by giving Seller not less than ten
(10) days prior written notice, to delay a scheduled takedown for a period of
ninety (90) days, in which event all subsequent takedowns shall occur ninety
(90) days after the date originally scheduled for such takedowns. Following the
exercise of the foregoing deferral right, provided Purchaser has subsequently
satisfied the quarterly takedown obligation for not less than three (3)
consecutive quarters, Purchaser shall have an additional one-time right,
exercisable in Purchaser's sole discretion by giving Seller not less than ten
(10) days prior written notice, to delay a scheduled takedown for a period of
ninety (90) days, in which event all subsequent takedowns shall occur ninety
(90) days after the date originally scheduled for such takedown.

          a. "Quarter" as used herein shall mean ninety (90) day periods.

          b. The Purchase Price for each Lot shall be increased at the rate of
one and one-half percent (1-1/2%) per Quarter. Said increase shall commence one
hundred eighty (180) days after the latter of (1) the date of the Model Lot
takedown per the Lot Purchase Agreement for the Executive Lots and (2) the date
of the Model Lot takedown per the Lot Purchase Agreement for the Estate Lots. In
the event Seller has not completed its obligations under this Agreement and is
unable to deliver finished Lots to satisfy Purchaser's take-down obligations,
and closing is delayed as a result thereof, the Purchase Price shall be the
amount Purchaser would have paid had the closing not been delayed, and increases
as above shall be abated accordingly.

     Purchaser shall have the right at any time to settle on more Lots than the
number of Lots required to be purchased in such Quarter, provided additional
Lots are available for early settlement. Purchaser shall receive credits toward
the minimum number of Lots required to be purchased in any period, for Lots
purchased in excess of the minimum number, and such credits shall be cumulative.

     6.   Additional Conditions to Closing for Lots.

     Prior to all settlements, each of the Lots shall have such improvements as
would allow Purchaser to obtain a building permit for the construction of a
dwelling unit thereon, and upon completion of such dwelling unit, a Certificate
of Use and Occupancy therefor assuming timely filing of all requisite
applications and payment of standard fees. Seller shall use commercially
reasonable efforts to complete the work described in Exhibit "B" attached hereto
and incorporated herein and in this section as to a number of Lots sufficient to
enable the initial

                                       -2-

<PAGE>

settlement within eighteen (18) months following the acquisition of the Property
by Seller, and shall thereafter complete such work as to additional Lots such as
will enable Purchaser to meet its minimum closing obligations set forth in
Section 5.

     7.   Transfer Imposts.

     Seller shall pay the Virginia Grantor's Tax and Purchaser shall pay all
other State and county transfer and recordation taxes assessed at or related to
each closing hereunder.

     8.   Settlement Costs.

     Cost of examination of title, title insurance, Purchaser's settlement fees,
Purchaser's attorneys' fees, and document preparation charges for the Deed, if
any, shall be at the sole expense of Purchaser. Seller shall be responsible for
its own settlement costs.

     9.   Place of Settlement.

     Closings as herein required shall be held at Walker Title or at such other
settlement agent's office within the Washington, D.C. Metropolitan Area or
within the jurisdiction in which the Property is located as Purchaser
designates.

     10.  Adjustments.

     All ad valorem taxes, metropolitan district charges, front foot or other
benefit charges or assessments, including deferred connection charges, if
applicable, and all other fees payable on an annual or periodic basis shall be
adjusted to the date(s) of closing and thereafter assumed by Purchaser. Seller
will be responsible for the payment of any presently enacted rezoning or
development tax which may be imposed on the Lots. Purchaser will be responsible
for any water and sewer capital facility connection charges and capital facility
assessment charges and any user fees applicable to the Lots, and if all or a
portion of the same has been paid by Seller prior to settlement, Purchaser shall
reimburse Seller at settlement for such charges on a pro-rata basis per Lots
settled.

     11.  Default.

          a. Purchaser's Failure to Close. In the event of Purchaser's wrongful
failure to close upon a Lot or Lots as provided herein, Seller's sole remedy
shall be specific performance as provided in Section 2.

          b. Seller's Default. Except as set forth in the last paragraph of
Section 13 of this Agreement, in the event of default by Seller, Purchaser's
sole and exclusive remedy shall be a suit for specific performance against
Seller with regard to the obligations of Seller.

          c. Notice and Cure. Except for payments by Purchaser required pursuant
to this Agreement, no failure or default by Purchaser or Seller, including
failure to timely exercise options, shall result in the termination or
limitation of any right hereunder or the exercise of any rights or remedies with
respect to such failure or default unless and until defaulting party shall have
been notified in writing and shall have failed to remedy said failure within
fifteen (15) days

                                       -3-

<PAGE>

after the receipt of said written notice. If such failure or default is not
curable within fifteen (15) days, then action to cure shall begin within fifteen
(15) days and be completed within thirty (30) days.

     12.  Seller's Representations.

     As of the Effective Date of this Agreement, Seller represents, warrants and
covenants as follows, and it shall be a condition precedent to Purchaser's
obligation to consummate closing(s) that none of the following has been breached
or would be breached if remade as of their respective date(s) of closing(s):

          a. For so long as this Agreement continues in effect, Seller shall not
cause any change in the Property from its present physical condition except as
required by governmental authorities and/or to finish the Lots, and shall not
commit any waste upon the Property.

          b. Seller will, during the terms of this Agreement, keep any existing
mortgage(s) against the Property current and not in default and cause to be paid
all taxes and other public charges against the Property so as to avoid
forfeiture of Purchaser's rights under this Agreement.

          c. With the exception of restrictive for the Woodland Village
HomeOwners Association Inc. and all other documents recorded or required to be
recorded to subdivide the finished Lots, Seller has not made and will not make
any commitments or representations to the applicable governmental authorities,
any adjoining or surrounding property owners, any civic association, any
utility, or any other person or entity, which would in any manner be binding
upon Purchaser or interfere with Purchaser's ability to utilize or develop the
Property, without Purchaser's prior written approval.

          d. There is no violation of any law, ordinance, order or regulation
affecting the Lots resulting from Seller's actions, and Seller agrees to take
all necessary action to correct any such future violation caused or created by
Seller prior to closing and to convey the Property free thereof.

          e. To the best knowledge of Seller, there are no hazardous or toxic
wastes or substances or petroleum waste or substances which are the subject of
any federal, state or local environmental or pollution control laws upon or
adjacent to the Property or any part thereof, and that it has received no
notification of, and has no knowledge of, any investigation of the Property or
any part thereof by the U.S. Environmental Protection Agency or any similar
federal, state or local governmental authority, and agrees to take all necessary
action to correct any such future violation caused or created by Seller prior or
after closing and to take such corrective action in order to convey the Property
free thereof.

          f. There is no action, suit, proceeding, inquiry or investigation at
law or in equity, before or by any court, public body or board or administrative
agency, pending or threatened, which in any way impairs title to the Lots and/or
creates an impediment to obtaining building permits for the Lots.

<PAGE>

          g. It has no knowledge of any pending or threatened condemnation
proceeding concerning any part of the Lots.

          i. The right of ingress to and egress from the Property, through
direct access to a dedicated public road or to a dedicated private road with
direct access to a dedicated public road, is reasonably available.

          j. All dedications or fees in lieu thereof (other than as set forth in
Section 14 hereof), or as otherwise specified herein, shall have been made or
paid by Seller.

          k. Seller shall provide Purchaser with all the information required to
be disclosed to Purchaser's third party purchasers, regarding the Homeowners'
Association for the Property. Seller shall have an ongoing responsibility to
deliver to Purchaser, in a timely manner, any substantial or material amendments
or changes to the information required to be delivered to Purchaser's third
party purchasers.

          l. This Agreement has been duly authorized by Seller and all of its
individual and corporate stockholders, partners, members and participants, and
the terms hereof do not violate and are not inconsistent with any by-law,
statute, regulation, document, judicial or administrative proceeding, or
anything else to which Seller is legally bound and/or a party.

          m. Seller is not a "foreign person" as defined in Section 1445(f)(3)
of the Internal Revenue Code as amended or replaced (the "Code"). At closing,
Seller shall execute the Affidavit required by Section 1445(b)(2) of the Code
and shall be responsible for filing such Affidavit as required. Seller shall
indemnify and hold Purchaser harmless against any and all claims arising out of
or relating to the execution, content or filing of the foregoing Affidavit.
Seller shall also comply with any other reporting requirements imposed by the
Code with respect to, or arising out of, the sale of the Property.

          n. Seller shall grant and provide such licenses, easements, and
rights-of-way as Purchaser reasonably deems necessary for Purchaser's access to
the Property and for Purchaser's ingress and egress and such other easements or
rights-of-way needed for the purpose of Storm Water Quality Management or
utility service, all of the foregoing not to materially interfere with
development by Seller or materially devalue Seller's Property. All of the
foregoing licenses, easements and rights-of-way shall conform with County
requirements and approvals.

          o. As of each closing date, all sureties, bonds, and/or letters of
credit required by the County or all other governmental agencies (including

posted by Seller, in the amount required by appropriate governmental agencies.

          p. Seller has disclosed, and provided Purchaser with copies of, any
and all proffers and agreements between Seller and the local government
officials, or otherwise affecting the Property, regarding the development of the
Property and construction of the Lots.

                                       -5-

          f. Seller shall install a duly authorized and approved public water

          g. Seller shall have prepared plans for the grading and sediment
control, storm drains, streets, curb, gutter, sidewalk, paving, landscaping and
other improvements within the Property and/or the public right-of-way and any
areas to be conveyed to the Homeowners'

                                       -6-

Association and obtained necessary approvals of such plans, including the site
plan from the County, and all other relevant jurisdictions.

          h. Seller shall have obtained final and unappealable approval(s) from
the County and all appropriate governmental authorities of all documents
required of Seller necessary so that Purchaser can obtain building permits for
the dwelling units to be constructed on the Lots to be settled, including but
not limited to, site plans, authorizations, street construction permits, and
allocations for water and sewer with hook-up approvals. Any such allocation,
quarterly user fees and/or fees paid for by Seller prior to settlement shall be
reimbursed to Seller by Purchaser at settlement.

          i. All engineering and site development plans for all Lots in Phase I
or Phase II as set forth on Exhibit "A", as applicable, shall have been

Seller's obligations and all development improvements herein referred to meet,
exceed and conform to all applicable Federal, State, County, City and other
local ordinances, regulations, standards and specifications.

          j. Except as otherwise provided for in this Agreement, Seller shall be
responsible for all special assessments imposed or assessed upon the Property
for improvements by governmental authorities completed prior to the date hereof
or required to be installed to develop the Property for the purpose and use
contemplated under this Agreement, except for any deferred charges including
front foot benefit charges regularly assumed by eventual house purchasers, which
shall be adjusted to the date of transfer.

          k. Seller shall cooperate with and deliver to Purchaser, at the sole
cost and expense of Purchaser, any and all things required to obtain, prepare or
cause to be prepared certain documents described in this subparagraph k, which
shall be in a form acceptable to Purchaser, such acceptance not to be
unreasonably withheld, and as may be required by the Veteran's Administration
(VA), Federal Housing Administration (FHA), and Federal National Mortgage
Association (FNMA). Seller agrees that it will, if required by any government
agency prior to the first settlement hereunder, amend any Declarations,
Articles, By-Laws or other Homeowners' Association documents to meet any agency
requirement, and supply Purchaser and the appropriate government agency all
information necessary to obtain requisite approvals. Anything to the contrary
notwithstanding, Seller shall not be entitled to reimbursement for overhead and
normal operating expenses in connection with the foregoing requirements of this
subparagraph k.

               (i) A Declaration of Covenants, Conditions and Restrictions (the
"HOA Declaration") imposing architectural and residential use restrictions on
the Lots and, if required, providing for a Homeowners' Association with annual
assessments against each Lot for the purpose of providing funds for the
maintenance of the open space and recreation areas, if any, shown on the
recorded subdivision plat, which recreation areas, and open space within areas
where said Lots are being settled, have been conveyed to the Homeowners'
Association by Seller prior to the time homeowner(s) settle on the first Lot(s).

                                       -7-

<PAGE>

               (ii) Articles of Incorporation for the Homeowners' Association.

               (iii) By-Laws for the Homeowners' Association. Seller, at or
prior to the first settlement on the Lots, shall record the HOA Declaration
among the Land Records of the County and shall record and file the Articles of
Incorporation for the Homeowners' Association with the Virginia State
Corporation Commission.

          l. The Lots to be conveyed hereunder shall be delivered free of
rubbish and/or debris.

          m. It is a condition of closing(s) that water and sewer shall be
installed to a Lot line and approved by the appropriate authority, fully
contracted for and paid for by Seller to a Lot line (except as provided in
Section 10 hereof).

          n. Seller shall be responsible to convey the Lots hereunder free from
any notices of violations by Seller of local ordinances or requirements issued
by legal authority or prosecutions of any court on account hereof.

     If Seller is unable or unwilling to complete or fulfill its obligations as
set forth above in Sections 12 and 13 for the Lots to be closed or settled upon
by the herein specified times for the closings thereon, Purchaser may at its
option (i) settle on said Lots to be closed upon notwithstanding Seller's
failure but without waiving Seller's obligations to perform hereunder, or (ii)
delay closing until after Seller has satisfied its obligations, and all
subsequent closing obligations of Purchaser shall be delayed for an amount of
time equal to said delay and shall be subject to price, terms and conditions
that would have been in effect prior to said delay, (iii) terminate this
Agreement, or (iv) proceed with such remedies as may be available to Purchaser
pursuant to Section 11 (entitled "Default") above. Anything to the contrary
notwithstanding, if Seller is unable to fulfill its obligations as set forth in
Sections 12 and 13 through no fault of Seller (e.g., moratorium imposed by
governmental action, acts of God, etc.), Purchaser's sole remedy in such event
shall be to (A) settle on said Lots notwithstanding such imposition, (B) delay
closing for a period not to exceed six (6) months or the end of such moratorium,
whichever shall first occur, or (C) terminate this Agreement.

     14.  Additional Undertakings of Seller.

          a. It shall be Seller's obligation to stabilize the Property in
accordance with governmental regulations. Except for construction of houses and
stabilization on Lots and green area, including building leadwalks, which shall
be constructed by Purchaser, Seller shall hold Purchaser harmless and indemnify
it with respect to any condition or requirement of Seller's Public Works
Agreements, Sediment and Soil Erosion Agreements, and Utility Agreements
affecting the Lots, except for any negligent or intentional act of Purchaser,
its contractors, subcontractors or employees. Anything to the contrary
notwithstanding, Seller shall be responsible at all times for stabilization of
recreation areas, except for any negligence or intentional act of Purchaser, its
contractors, subcontractors or employees.

          b. Seller, at its own expense, shall be responsible for snow removal
and street cleaning for public streets on the Property until the Homeowners'
Association or County or other local government entity shall assume such
responsibilities. Said public street cleaning and snow

                                       -8-

<PAGE>

removal shall be the sole responsibility and at the sole cost of Seller.
However, any street cleaning needed as a result of Purchaser's construction
activities on the Lots shall be the responsibility of Purchaser, at its sole
cost.

     15.  Storage of Construction Equipment.

     Seller shall provide space, within its Property, for the storage of
construction equipment, storage facilities and material which Purchaser's
subcontractors may from time to time reasonably require which shall be
temporarily screened from view if reasonably requested by Seller for aesthetic
reasons, which screening shall be comprised of the least expensive materials,
which do not materially detract from the aesthetics of the Property. Such space
shall be located in an area which would be easily accessible to Purchaser's
subcontractors and shall be located so it will not be detrimental to the
marketing of Purchaser's homes. Such space shall be made available at no cost to
Purchaser. Purchaser shall hold Seller harmless and indemnify it from any
liability Seller may incur for any damage to property or injury to third persons
which may result from Purchaser's utilization of the storage area. After the
settlement of the last Lot pursuant to the terms of this Agreement, or upon
earlier termination of this Agreement, any materials or equipment stored on the
storage area shall be removed and/or disassembled, and Purchaser shall be
responsible for restoring said area into the same condition as existed
immediately prior to Purchaser's utilization of the storage area.

     16.  Model Home Sites; Sales, Construction and Administration Trailers.

     Purchaser and Seller shall coordinate and agree upon the number, location
and types of model homes, sales, construction and administration trailers or
offices that may placed upon the Lots, and such uses shall be in compliance with
all applicable governmental laws, rules and regulations.

     17.  Marketing Signs.

     At all times during the term of this Agreement, Purchaser shall have the
right to erect and maintain marketing signs, of its own choice, on the Property
(including, without limitation, "For Sale" and "Sold" signs on any of the Lots)
in accordance with all governmental regulations, and subject to the approval of
Seller, which approval shall not be unreasonably withheld. It is the intention
of Seller and Purchaser that all signs within the community will be of similar
design and color as approved by Seller.

     18.  Additional Undertakings and Warranties.

          a. Purchaser shall not seek any site plan, phasing plan or development
plan amendment without the prior written approval of Seller, which approval
shall not be unreasonably withheld. In the event that Seller shall not have
responded to the submission of such plans within ten (10) days of receipt of
same, they shall be deemed approved by Seller.

          b. Purchaser shall maintain all of its construction sites in an
orderly fashion and shall remove all debris and equipment, resulting from
Purchaser's activity, in a timely fashion.

                                       -9-

<PAGE>

          c. Neither party shall permit mud, silt or construction debris to
accumulate upon any public or private street or road, and the responsible party
agrees to promptly clean such street or road, if required.

          d. Purchaser shall defend and hold Seller harmless from and against
any and all claims or suits resulting from or arising out of the construction by
Purchaser of its houses upon the Property, including reasonable legal and expert
fees incurred, provided Seller shall have given prompt notice to Purchaser of
any claim against it.

          e. Seller shall defend and hold Purchaser harmless from and against
any and all claims or suits resulting from or arising out of the conduct of
development or other work by Seller upon the Property provided Purchaser shall
have given prompt notice to Seller of any claim against it.

          f. Purchaser's sales contracts with individual homeowners/purchasers
for the Lots shall reference the Woodland Village HomeOwners Association Inc.
and shall require Purchaser to comply with all applicable provisions of the
Virginia Property Owners Association Act

     19.  Quality of Title.

     It is a condition of Purchaser's obligation hereunder that title to the
Lots be good and marketable, free of liens and encumbrances, and insurable by a
title insurance company holding membership in the American Land Title
Association at regular rates, subject to no conditions or encumbrances such as
would inhibit or prevent or impose any material burden or expense upon the
development of the Lots for residential purposes and the construction of
residential dwelling units thereon as Purchaser reasonably desires (other than
for expenses which Purchaser has agreed to pay). In the event title is
unacceptable to Purchaser and Purchaser so notifies Seller, Seller shall, within
five (5) days after receipt of such notice from Purchaser, notify Purchaser in
writing either (i) that Seller is unwilling or unable to correct such
unacceptable matters, or (ii) that Seller at its sole cost and expense shall
undertake promptly to eliminate or modify all such unacceptable matters to the
reasonable satisfaction of Purchaser. In the latter event, Seller agrees to use
its diligent efforts to promptly satisfy any such objections. In the event
Seller elects not to cure such unacceptable matters or is unable with the
exercise of due diligence to satisfy said objections within fifteen (15) days
after said notice, Purchaser may, at its option, (i) accept title and proceed to
closing without an adjustment of the Purchase Price, or (ii) rescind this
Agreement with respect to the affected Lot(s), whereupon this Agreement shall be
of no further force and effect with respect to the affected Lot(s) and the
applicable pro-rata share of the Deposit shall be returned Purchaser. The
applicable pro-rata share of the Deposit to be returned to Purchaser shall be
equal to (a) the number of affected Lots, divided by (b) the total number of
Lots that Purchaser is obligated to purchase under Section 2 above. Failure of
Purchaser to notify Seller of title defects prior to the scheduled date of
closing shall be deemed an acceptance by Purchaser of the then existing title of
Seller.

     Upon request by Purchaser, Seller shall execute such reasonable affidavits
and other similar type instruments as are required by Purchaser's title
insurance company relating to the status of title and for the elimination of any
standard or printed exceptions in Purchaser's final

                                      -10-

<PAGE>

policy of title insurance, including, without limitation, the exception for
unfulfilled mechanics' liens.

     20.  Conveyance of Title.

     Seller agrees to execute, acknowledge and deliver at each of the several
closings, deeds of conveyance containing covenants of special warranty and
further assurances as may be required.

     21.  Possession and Risk of Loss.

     Possession of the Lots shall be delivered at time of closing thereon. The
risk of loss or damage to the respective Lots by fire or other casualty is
assumed by Seller until the date of closing thereon, except damage caused by
Purchaser in connection with Section 25 of this Agreement.

     22.  Brokerage.

     Seller and Purchaser each represent to the other that they have dealt with
no agent or broker with respect to the transaction contemplated by this
Agreement. Seller shall defend, indemnify, and hold Purchaser harmless, and
Purchaser shall defend, indemnify, and hold Seller harmless, from and against
any loss, cost, expense, claim or cause of action of any nature (including, but
not limited to, court costs and reasonable attorneys' fees), arising from or out
of any breach of the foregoing representation by the respective indemnitors.

     23.  Notices.

     All notices, demands, and communications ("Notices") permitted or required
to be given hereunder shall be in writing and shall be deemed duly given when
(i) hand delivered, or (ii) sent by commercial overnight courier, or (iii)
mailed, registered or certified United States Mail, return receipt requested,
first class, postage prepaid. Notices shall be addressed to Seller or Purchaser,
as the case may be, at the address shown below or to such other address of which

     24.  Eminent Domain (Condemnation).

     In the event condemnation or eminent domain proceedings (or private
purchase in lieu thereof) are commenced by any public or quasi-public authority
having jurisdiction against all or any part of the Lots, Seller shall promptly
so notify Purchaser. In the event that the condemnation takes all or any portion
of a Lot, Purchaser may, at its option by giving written notice to Seller, (i)
close on one less Lot than required under Section 2 above, or (ii) agree to
proceed to closing on such affected Lot, in which event Seller shall assign to
Purchaser at closing thereon any awards in condemnation and all rights in
connection with such condemnation relating to the affected Lot.

     25.  Right of Entry.

     Provided there is no interference with Seller's development activities,
Seller shall permit Purchaser access to such portion of the Property as it shall
not have then acquired at all reasonable times for the purpose of performing
soil and engineering studies, sediment control or such other work as Purchaser
shall deem necessary or desirable in connection with its construction on the
Lots. Any damage by Purchaser to Property not conveyed to it shall be promptly
repaired by Purchaser. The cost of all such undertakings by Purchaser shall be
borne by Purchaser. The provisions of this Section shall survive termination of
this Agreement.

     26.  Indemnification.

     Purchaser agrees to indemnify, defend and hold Seller harmless from and
against any liabilities, obligations, claims, damages, demands, penalties,
causes of action, costs and expenses, including, without limitation, reasonable
attorneys' fees and expenses, whether arising out of injury or death to persons
or damage to the Property resulting from any wrongful act of Purchaser, its
contractors, subcontractors, officers, agents and employees in consequence of
Purchaser's entry onto such portions of the Property as shall then be owned by
Seller, as permitted by Section 25 above. This provisions of this Section shall
survive termination of this Agreement.

     27.  Approval of Purchaser's House Types.

     Seller warrants and represents that to the best of its information and
belief, no private person,  firm or corporation, except Seller and the HOA
architectural review committee and board of directors, has the right to restrict
or limit Purchaser in the size, design, placement on the

                                      -12-

<PAGE>

Lot, cost or any other aspect of the dwellings intended to be constructed by
Purchaser on the Lots. Seller shall timely review and not unreasonably withhold
approval of any house type, landscape plan and lot grading plan submitted by
Purchaser for approval, and shall deliver to Purchaser upon Purchaser's request
confirmation by Seller and the HOA architectural review committee (if
applicable) of their approval thereof.

     28.  Force Majeure.

     In the event that after written notice to the other party either party
hereto shall be unintentionally or uncontrollably delayed, hindered or prevented
from the performance of any act required hereunder by reason of insurrection,
war, acts of God, governmental delay, adverse weather conditions, or other
reason of like nature, not the fault of the party delayed in performing work or
doing acts required under the terms of this Agreement, then performance of such
act shall be excused for the period of the delay, and the period for this
performance of any such act shall be extended for the lesser of (i) six (6)
months after written notice, or (ii) the time of such delay. If, upon the
expiration of the extension period, the required performance remains
unperformed, either party may at its option declare this Agreement null and
void; in such event, Purchaser's then remaining deposit shall be returned to
Purchaser, and there shall be no further liability on the part of either party
to the other. The aforesaid written notice must be given within ten (10) days
after the event of delay, or such delay shall be deemed waived.

     29.  Moratorium.

     If the State or County, or any agency or subdivision thereof, declares a
moratorium on the issuance or use of permits for construction and/or occupancy
of residential dwellings within the Property and/or construction of improvements
required to be constructed by Seller, and because of such moratorium the County
will not issue any permits for the construction of Seller's improvements or use
and occupancy of any single family dwellings upon the Property, then either
party hereto, upon written notice to the other party, may extend the settlement
date of the next occurring settlement for the length of the moratorium, but not
in excess of six (6) months. If, upon expiration of this period, the moratorium
remains in effect, Purchaser or Seller may at its option either waive said
condition and forthwith continue to settle Lots as provided herein or declare
this Agreement null and void; and there shall be no further liability on the
part of either party to the other. In the event of such delay, the price, terms
and conditions of the next occurring settlement shall be subject to those which
existed prior to said delay.

     30.  Survival.

     All representations, warranties, covenants, agreements and indemnifications
set forth in or made pursuant to this Agreement shall remain operative and shall
survive the closing(s) on the purchase of Lots and the execution and delivery of
the deeds to Lots conveyed pursuant to this Agreement and shall not be merged
therein. In addition, if this Agreement is terminated pursuant to the terms
hereof, by either Purchaser or Seller, the representations, warranties,
covenants, agreements and indemnifications set forth herein or made pursuant to
this Agreement and accrued on or before the such termination, shall nevertheless
survive such termination and settlement of Lots.

     31.  Entire Agreement.

     This Agreement, together with all exhibits and schedules attached hereto,
contains the entire agreement between the parties hereto and is intended to be
an integration of all prior agreements, conditions or undertakings between the
parties hereto. Except as expressly set forth herein or as contained in
contemporaneous written agreements, there are no promises, agreements,
conditions, undertakings, warranties or representations, oral or written,
expressed or implied, between Purchaser and Seller.

     32.  Relationship of the Parties.

     Notwithstanding any other provision of this Agreement, or any agreements,
contracts or obligations which may derive herefrom, nothing herein shall be
construed to make the parties hereto partners or joint venturers, or to render
either party liable for any of the debts or obligations of the other party, it
being the intention of this Agreement to merely create the relationship of
Seller and Purchaser with regard to the Property and the particular Lots to be
conveyed hereby.

     33.  Amendments; Waivers.

     No change or modification of this Agreement shall be valid unless the same
is in writing and signed by Purchaser and Seller. No purported or alleged waiver
of any of the provisions of this Agreement shall be binding or effective unless
in writing and signed by the party against whom it is sought to be enforced.

     34.  Assignment of Agreement.

     Purchaser shall not have the right to assign this Agreement, in whole or in
part, without prior written consent of Seller, which consent may be withheld in
Seller's sole and absolute discretion. Notwithstanding the above, Purchaser may
assign its rights and obligations hereunder, to an "Affiliate" (as hereinafter
defined) without Seller's consent, provided Purchaser remains liable pursuant to
the terms of this Agreement. The term "Affiliate" shall mean and refer to (a)
any officer, director, trustee, partner, employee or holder of fifty percent
(50%) or more of any class of the voting securities of or equity interest in
Purchaser; (b) any corporation, partnership, trust or other entity controlling,
controlled by or under common control with Purchaser; (c) any officer, director,
trustee, partner, employee or holder of fifty percent (50%) or more of the
outstanding voting securities of any corporation, partnership, trust or other
entity controlling, controlled by or under common control with Purchaser; and
(d) any relative or spouse (or any relative of such spouse) of any natural
person included in clauses (a) or (c) above, who shares the same home as such
natural person. In the event that such assignment, transfer or conveyance is
approved by Seller, and such assignment, transfer or conveyance is to a
non-Affiliate of a Purchaser, then any "Excess Consideration" (as hereinafter
defined) payable by the assignee shall be paid to the Seller. The term "Excess
Consideration" shall mean the amount, if any, by which (i) the aggregate net
consideration which the approved assignee pays to the Purchaser, exceeds (ii)
any out-of-pocket costs and expenses (including the purchase price paid by
Purchaser) paid by Purchaser, in connection with its acquisition of such Lots
pursuant to this Lot Purchase Agreement.

this Agreement or any portion hereof or would limit the time during which this
entire Agreement or any portion hereof shall be effective due to the potential
failure of any interest in property created herein to vest within a particular
time, then each such interest in property shall be effective only from the date
hereof until the passing of twenty-one (21) years after the death of the last
survivor of the members of the Senate of the United States of America
representing the Commonwealth of Virginia who are serving on the date hereof,
but each such interest in property shall be extinguished after such time, and
all other interests in property created herein and all other provisions hereof
shall remain valid and effective without modification.
