                             LOT PURCHASE AGREEMENT
                                (EXECUTIVE 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, 54 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.

     Initial settlement shall be for one (1) model Lot and shall take place as
set forth in Section 6 below. Commencing 180 days following the initial
settlement, 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 this 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.

     Initial settlement for model Lot shall take place on or before fifteen (15)
days from the date on which Seller notifies Buyer that (i) building permits for
such model Lots are issuable by Loudoun County, assuming timely filing of all
requisite applications and payment of standard fees; (ii) there is construction
access available to the model Lot; and (iii) the Lots are cleared and graded as
required under this Agreement. Thereafter, prior to all subsequent settlements,
each of the Lots shall have such improvements as would allow Purchaser to obtain
a building permit for


                                       -2-

<PAGE>

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 settlement on the model lot within
twelve (12) 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.


                                       -3-

<PAGE>

          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 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.

          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

<PAGE>

required, providing for a Homeowners' Association with annual assessments

          n. Seller shall be responsible to convey the Lots hereunder free from

     If Seller is unable or unwilling to complete or fulfill its obligations as

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)

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

its contractors, subcontractors or employees. Anything to the contrary
notwithstanding, Seller shall be


                                       -8-

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 removal shall be the sole

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


                                       -9-

<PAGE>

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.

          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


                                      -10-

<PAGE>

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 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,

     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


                                      -12-

<PAGE>

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 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


                                      -13-

<PAGE>

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


                                      -14-

<PAGE>

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.

     35. Applicable Law.

     This Agreement shall be governed by and construed in accordance with the
laws of the Commonwealth of Virginia, without regard to its choice of law
provisions.

     36. Perpetuities.

     If the rule against perpetuities or any other rule or law would invalidate
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.

     37. Counterparts.

     This Agreement may be executed in two or more counterparts, each of which
shall be deemed an original, but all of which together shall constitute one and
the same instrument.

     38. Authority.

     Each party warrants to the other that it has full corporate authority to
enter into and perform this Agreement, and that the parties executing this
Agreement for each of them have been fully authorized to do so. Purchaser
represents to Seller that Purchaser is duly organized, validly existing and in
good standing under the laws of the Commonwealth of Virginia, and qualified to
do business in the jurisdiction in which the property is located. Seller
represents to Purchaser that Seller is duly organized, validly existing and in
good standing under the laws of the Commonwealth of Virginia.

     39. Effective Date.

     The Effective Date of this Agreement shall be the later date on which it
has been executed by both Purchaser and Seller as indicated on the signature
page below.

     40. Miscellaneous.

          a. All notices of violations of orders or requirements noted or issued
by any County or local authority, or actions in any court on account thereof
against or affecting the


                                      -15-

<PAGE>

Property at the date of settlement of this Agreement shall be complied with by
Seller and the Property conveyed free thereof.

          b. Seller certifies that Seller has no knowledge of any published
preliminary or adopted zoning map amendment which may result in condemnation or
taking of any part of Seller's Property.

          c. Partial Invalidity. If any term, covenant or condition of this
Agreement or the application therefor to any person or circumstance shall be
invalid or unenforceable, then the remainder of this Agreement or the
application of each term or provisions to persons or circumstances other than
those to which it is held invalid or unenforceable shall not be affected
thereby, and each term shall be valid and enforceable to the fullest extent
permitted by law.
