Any  documents  not  provided  by Seller to Buyer  within the above ten (10) day
period  will be made  available  by  Seller,  as  soon  as  such  documents  are
available.  In the event of any such  failure to deliver any  documents,  except
those  which  are  not  in  Seller's  possession  and  which  are  so  qualified

copies of each and every report it receives  immediately  upon their  completion
and availability to Buyer.

            (ii) During the Due Diligence Period, Buyer will conduct a review of

required by its funding  source,  including  inspection  of all zoning and other
government  permits and regulations and other matters and documents  relating to
the operation of the Property, and as detailed in Section 3(a).

            (iii) After Seller  provides  all  required  documents to the Buyer,
Buyer  agrees  to accept or  reject  all  documents  prior to the end of the Due
Diligence  Period.  If Buyer  does  not  cancel  this  Contract  during  the Due
Diligence  Period,  Buyer shall be deemed to have  accepted  the Property and it
will  close on the  Property  in  accordance  with  this  Contract,  except  for
cancellation in accordance with the specific provisions of this Contract.

      (b) This Contract is contingent upon Buyer  obtaining a "firm"  commitment
(per the practice of HUD for 221D4 mortgages) for financing the purchase of Real
Property in accordance with the Contract upon terms and conditions  satisfactory
to Buyer. Buyer agrees to apply for said commitment  promptly after December 20,
1996, and shall have a period of 85 days to obtain said commitment. Should Buyer
be unable to obtain said commitment within said 85-day period,  either party may
terminate this Contract by written notice to the other in which case the Earnest
Money  shall be  returned  to Buyer and  neither  party  shall have any  further
liability,  except the  obligation to restore the premises  after due diligence.
Buyer shall have the right to extend the mortgage  contingency  period for up to
30 days on prior written notice to Seller if the mortgage application is through
HUD.

      SECTION 4.  DEED AND TITLE.

            (a) Seller shall  deliver to Buyer at Closing,  a special or limited
warranty deed (or bargain and sale deed, where appropriate) ("Deed"),  conveying
good and  marketable  fee simple  title to the  Property,  subject  only to such
easements,  restrictions  of  record  and  title  exceptions  set  forth  in the
commitment for title  insurance  specifically  approved by Buyer,  and taxes not
delinquent.  Further,  the title  insurance  commitment  for the  Property  must
contain provision for the endorsements  that are reasonably  required by Buyer's
funding source, which endorsements shall be ordered by Buyer at Buyer's expense.
In addition,  Seller shall convey title to the Personal  Property to Buyer, free
and clear of all liens and  encumbrances  (except  those  disclosed  during  due
diligence;  e.g., equipment leases or personal property financing documents), by
the  execution  and delivery at Closing of a Bill of Sale in form and  substance
reasonably satisfactory to Buyer, without warranty, except as to Seller's title.

            (b) Seller agrees to provide a copy of its existing title  insurance
policy  to  Buyer.  Buyer  shall  then  obtain  an ALTA  Form B Title  Insurance
Commitment  (the  "Title  Commitment"),  within  thirty (30) days of the date of










                                       6


<PAGE>

commencement  of  Buyer's  due  diligence  period,  issued by a title  insurance
company selected by Buyer,  committing to insure fee simple  marketable title to
the  Property in the amount of the Purchase  Price for such  Property in Buyer's
name,  with all standard  exceptions  removed  (except for the rights of tenants
under  unrecorded  leases  and/or  except for standard  exceptions  normally not
removed pursuant to local custom with respect to each Property),  and containing
no other  exceptions not  specifically  approved by Buyer.  Buyer shall have ten
(10) days after  receipt to examine the Title  Commitment  and inform  Seller of
Buyer's objection to any exception  contained in or title defect revealed by the
Title Commitments.

            (c) If Buyer's  examination of the Title Commitment reveals that the
Title Commitment for the Property contains objectionable  exceptions or that the
title to the Property is defective and  thereafter,  the issuing title insurance
company refuses to delete the objectionable  exceptions or the defects cannot be
cured  within a  reasonable  period  of time  after  written  notice  by  Buyer,
specifically pointing out the objection/defects, or if the title company refuses
to issue  endorsements  as required by Buyer's  lender,  then Buyer may elect to
terminate  this Agreement  upon written  notice to Seller.  Notwithstanding  the
foregoing,  however,  in order  to  terminate  the  Contract,  an  objectionable
exception or defect must be one which renders title unmarketable and uninsurable
because of such  specified  objection or defect,  or the specified  objection or
defect shall be materially  inconsistent with the present use of the Property as
an apartment complex.

            (d)   Seller will pay for preparation of the Deed for the Property.

            (e) Buyer will pay for any survey of the Property,  the recording of
the Deed for the Property,  state tax and register's  fees on the Deed, the cost
of  obtaining a title  commitment,  and the premium due for the title  insurance
policy to be issued for the Property, and all endorsements.

            (f)   Seller and Buyer will each pay their own attorney's fees.

      SECTION 5.  PRORATIONS AND ALLOCATIONS.  (a)  Rents,  taxes,  service con-
tracts, equipment leases or other personal property financing, utility deposits,
insurance and other expenses  whether or not a lien,  assessed or to be assessed
for the tax year in which the transaction is consummated. will be prorated as to
the Property to the date of the Closing based on a 365-day year.

            (b)  Security  deposits  held by Owner or paid by any lessees at the
Property will be transferred to Buyer in full at Closing, including any interest
earned thereon and payable to the Tenant under State law.

prompt  written  notice of any fire or other  casualty  occurring  to all or any

hereof and the date of closing. If prior to the closing, there shall occur:

            (i) damage to the  improvements  at the  Property  caused by fire or

the foregoing,  should Buyer elect to terminate,  Seller may notify Buyer within
15 days that  Seller  intends to restore the  Premises  fully and in that event,
Buyer's  termination  notice shall be null and void and Seller shall  proceed as
outlined above at closing.

            If, prior to the closing, there shall occur:

            (i) damage to the Property  caused by fire or other  casualty  which
would cost less than 5% of the allocable Purchase Price of the Property based on
the  estimate of a reputable  third party  contractor  chosen by Seller to which
Buyer has no reasonable objection; or

            (ii) the taking or  condemnation  of all or any  portion of the said
Real Property and/or improvements as aforesaid which is not material to the use,

insurance  proceeds  or  condemnation  awards  which may be payable to Seller on
account of any such occurrence, and in addition, Buyer shall be allowed a credit
for any deductible under Seller's insurance policy.

the parties may agree,  and in that event the Earnest Money shall be returned to
Buyer.  However, in the event that all conditions specified herein have been met
by the  Closing  date,  Buyer shall  close the  Purchase  within the time period
specified, subject to non-performance by Seller under the terms hereof.

      SECTION 8.  SELLER'S WARRANTIES.  The following warranties of Seller shall
survive the Closing for a period of sixty (60) days.

            (a) The legal description of the Property  contained in the recitals
to this Agreement is  substantially  correct and will be confirmed by any survey
obtained by Buyer.

            (b) To Seller's best knowledge and belief (Seller  meaning Joseph M.
Jayson or an officer of the general  partner of Seller)  Seller has not received
written  notification  that the Property is not in compliance  with all federal,
state, county and municipal laws, ordinances and regulations,  including but not
limited to all  federal,  state,  county and  municipal  environmental  laws and
regulations,  applicable to or affecting the Property, subject to Seller's right
to cure as hereinabove stated.

            (d) Seller will convey fee simple,  marketable or insurable title to
the Property to Buyer at Closing and will convey title to the Personal  Property
to  Buyer  at  Closing  by  Bill  of  Sale,  in form  and  substance  reasonably
satisfactory to Buyer, free and clear of all liens and encumbrances.

            (e) Seller  will not  interfere  with  Buyer's  opportunity  to hire
Seller's  on-site  employees,  who work at the Property,  but Buyer will have no
obligation to hire any of those individuals.  Buyer will make no efforts to hire
such employees  until after all  contingencies  have been removed and no earlier
than 10 days before closing.

            (f) Seller shall be responsible  for (and Buyer shall not assume the
obligation  of) all employee  wages,  benefits  (including  payments for accrued
bonuses,  vacation or sick pay,  unemployment  compensation,  employment  taxes,
medical claims or similar payments),  contributions under any benefit program or
agreement, severance pay obligations and other related employee costs arising as
a result of any events, acts (or failures to act) prior to the Closing Date with
respect to the  Property  at which such  persons  are  employed,  whether or not
disclosed on the schedules to this Agreement.

            (g) Seller retains all liability and  responsibility  for fulfilling
all  federal  and/or  state COBRA and  continuation  of group  health  insurance
coverage  requirements  (pursuant to Section 4980B of the Code, sections 601-608
of ERISA,  and any  applicable  state laws) with respect to Seller's  current or
former employees (and their  dependents).  Buyer does not hereby and will not at
the Closing of the Property assume any obligation to provide  medical  insurance
coverage to persons that it employs because it acquires the Property.

      SECTION 9.  NON-PERFORMANCE.

            (a)   If  Seller  fails  to  deliver  the  Deed  or  meet any of the
conditions hereof willfully,  Buyer, at Buyer's sole option,  may terminate this
Agreement  whereupon  the Earnest  Money shall be returned to Buyer on demand or
Buyer may bring an action for specific performance,  and if Buyer prevails,  all
costs and  expenses of any such action shall be paid by Seller as a reduction of
the Purchase  Price.  The  foregoing  shall not prevent  Buyer from  bringing an
action for  monetary  damages.  The  foregoing  shall be the sole and  exclusive
remedies  of Buyer.  However,  if Buyer  elects to bring an action for  monetary
damages,  they shall be specifically  limited,  if proven, to an amount equal to
the Earnest Money as set forth hereinabove.

            (b) If Buyer  defaults  at any time,  Seller and Buyer agree that it
will be extremely  difficult or  impractical  to fix  Seller's  actual  damages.
Therefore,  in such an event,  the entire  Earnest  Money shall be  delivered to
Seller as liquidated  damages for loss of a bargain and not as a penalty.  Buyer
will then be released  from all liability to Seller  related to this  Agreement,
such liquidated damages being Seller's sole remedy.

      SECTION  10.  BROKERS,  AGENTS  AND  CONSULTANTS.  Seller  represents  and
warrants to Buyer that no broker, consultant or agent is due a commission or fee
from the  proceeds of the  Closing,  claiming  by,  through or under  Seller and
hereby agrees to indemnify and hold harmless Buyer from the claims of any agent,
consultant or broker for the payment of a commission or commissions.











                                       11


<PAGE>

      Buyer  represents and warrants to Seller that no other broker,  consultant
or agent is due a commission  or fee from the  proceeds of the closing  claiming
by,  through or under Buyer,  and hereby  agrees to indemnify  and hold harmless
Seller and the Property from the claims of any other agent, consultant or broker
for the payment of any commission, finder's fee or other compensation.

      SECTION 11.  LEASES.

            (a) Seller  agrees  that prior to the Closing it will not enter into
any long term commercial leases or service  agreements without the prior written
consent of Buyer  which  will not be  unreasonably  withheld  or  delayed.  This
provision  shall not be  applicable  until after the  expiration  of Buyer's Due
Diligence Period.

            (b) Seller  shall  assign  the  existing  tenant  leases to Buyer at
Closing  along with all service  contracts  and other  agreements  affecting the
Property,  provided that Buyer shall  execute an  assumption  agreement or other
agreements  with  respect to all tenant  leases and service  contracts  or other
agreements from and after the date of closing.

      SECTION 12.  INSURANCE.  Seller will cancel its  insurance coverage on the
Property  effective  at  Closing  of the  Property,  and  Buyer  will  place new
insurance coverage on the Property effective on the same date.

      SECTION  13.  ASSIGNMENT.  Buyer  shall not have the right to assign  this
Agreement,  in whole or in part,  to any party  with  whom it is not  affiliated
without the express written consent of Seller. Upon any such assignment approved
by Seller,  the assignee shall assume the obligations of Buyer and provided said
consent is obtained,  Buyer shall  thereafter  be relieved of liability  for the
performance of this Agreement.  Seller's  consent pursuant to this section shall
be in its sole discretion and shall include approval of all proposed  assignment
documents.

      SECTION 14.  ENTIRE AGREEMENT.  All prior understandings and agreements of
the  parties  are  merged  herein,   and  this  Agreement  reflects  the  entire
understanding  of the parties.  This  Agreement may not be changed or terminated
orally.

      SECTION 15.  SUCCESSORS AND ASSIGNS.  The terms of this Agreement shall be
binding upon and inure to the benefit of the parties  hereto,  their  respective
legal representatives, successors and assigns.

      SECTION 16.  INDEMNIFICATION.

            (a) SELLERS INDEMNITY. Seller shall indemnify, defend and hold Buyer
harmless from any claims, demand, loss, liability, damage, or expense (including











                                       12

<PAGE>

reasonable  attorneys' fees) in connection with third-party claims for injury or
damage to personal property in connection with the ownership or operation of the
Properties prior to Closing.  These indemnification  obligations of Seller shall
be repeated at and shall survive the Closing.

            (b) BUYERS INDEMNITY. Buyer shall indemnify,  defend and hold Seller
harmless from any claim, demand, loss, liability,  damage, or expense (including
reasonable  attorneys'  fees),  due to Buyers operation of the Property from and
after Closing. The indemnification obligations of Buyer shall be repeated at and
shall survive the Closing.

      SECTION 17. NOTICES.  All notices required or permitted hereby shall be in

objection from the other party to the proposed  payment within five (5) business

the extent  allowable by law, Buyer shall assign the Bond Cap allocation and all
related  approvals or commitments with respect to such Property to Seller or its
designee  wherever  possible  and/or if allowed by any lender or other authority
and Buyer  will  cooperate  with  Seller in all  respects  with  respect  to any
