      Buyer may cancel this agreement for ANY REASON in its  sole
discretion by delivering a cancellation notice by certified mail,
return  receipt requested, or by personal delivery to Seller  and
escrow  holder before the expiration of the Review  Period.  Such
notice shall be deemed effective when transmitted (as defined  by
Subparagraph 18(d)) to Seller.  If this Agreement is not canceled
as  set  forth  herein, the First Payment shall be non-refundable
unless Seller shall default hereunder.

      If  Buyer  cancels this Agreement as permitted  under  this
Section,   except   for   any  title  insurance   and/or   escrow
cancellation  fees and any liabilities under the first  paragraph

evidence  the  termination hereof) shall be  returned  its  First
Payment,  and  Buyer will have absolutely no  rights,  claims  or

instructions   together   with  the  escrow   holder's   standard
instructions  and  any additional instructions  required  by  the
escrow  holder to clarify its rights and duties (and the  parties
agree  to  sign these additional instructions). If there  is  any
conflict  between  these other instructions and  this  Agreement,
this Agreement will control.

8.    Title. Closing will be conditioned on the commitment  of  a
nationally  recognized title company selected by Seller,  subject
to  the  approval  of Buyer's lender or mortgagee,  to  issue  an
Owner's  policy  of title insurance, dated as  of  the  close  of
escrow,  in an amount equal to the purchase price, insuring  that
Buyer  will own marketable and insurable fee simple title to  the
Property subject only to: the Permitted Exceptions as defined  in
paragraph  2 above;  current real property taxes and assessments;
and, survey exceptions.

      Buyer  shall be allowed until the expiration of the  Review
Period  for examination of the commitment and the making  of  any
objections  to  marketability  of  title  thereto,  or  that   an
exception  to  title adversely affects the use of  the  Property,
said  objections to be made in writing or deemed  waived.   Buyer
shall  provide  Seller with a copy of said title commitment.   If
any objections thereto are so made by Buyer, the Seller shall  be
allowed  ten  (10)  days to make such title  marketable  or  cure
Buyer's  objections, or in the alternative to obtain a commitment
for  insurable title insuring over Buyer's objections.  If Seller
shall  decide to make no efforts to make title marketable, or  is
unable to make title marketable or obtain insurable title, (after
execution  by  Buyer  of such documents reasonably  requested  by
Seller  to evidence the termination hereof) Buyer's First Payment
shall  be returned and this agreement shall be null and void  and
of  no further force and effect.  In such event, Buyer shall have
no liability for the funds expended by Seller for all  reasonable
costs  incurred with respect to updating title and survey as  set
forth  in  Paragraph  6 and Seller shall be responsible  for  all
Escrow Fees charged in connection with this Agreement.

     Pending correction of title, the payments hereunder required
shall  be postponed, but upon correction of title and within  ten
(10)  days  after written notice of correction to the Buyer,  the
parties shall perform this agreement according to its terms.

      If  Buyer shall make no written objection to Seller  within
the  Review Period setting forth Buyer's objections to the status
of  title, Buyer shall have been deemed to have waived  any  such
objections.

9.   Closing  Costs.  Seller will pay the real property  transfer
tax  and   conveyance fees and one-half of escrow fees,  and  any
brokerage  commissions payable except those brokerage commissions
incurred by Buyer.  Seller shall pay for the cost of issuing  the
title  commitment, and will pay the cost of the  title  insurance
premium for an Owner's policy, (if Buyer shall decide to purchase
the  same).  Buyer shall pay all recording fees, one-half of  the
escrow  fees,  and  the cost of any special endorsements  to  the
title  policy as may be required by Buyer.  Each party  will  pay
its  own attorneys' fees and costs to document and close of  this
transaction.

10.   Real  Estate  Taxes,  Special Assessments  and  Prorations.
Seller represents that all real estate taxes and installments  of
special  assessments due and payable in all years  prior  to  the
year  of Closing have been paid in full.  Responsibility for real
estate taxes and special assessments shall be prorated as of  the
date  of closing based upon the most recently available tax  bill
with  no  readjustment for the taxes due for the  year  in  which
closing   shall  occur.   All  real  estate  taxes  and   special
assessments  due and payable in the years following the  year  in
which  closing  occurs shall otherwise be the  responsibility  of
