ITEM 2 - Disposition of Assets

   The Lakes at South Coast Apartments, Costa Mesa, California

   Disposition Date - August 20, 1998

      On August 20,  1998,  The Lakes Joint  Venture,  a joint  venture in which
PaineWebber Development Partners Four, Ltd. ("the Partnership") has an interest,
sold the property known as The Lakes at South Coast Apartments  located in Costa
Mesa,  California,  to an  unrelated  third  party,  Casden Lakes LP, a Delaware
limited partnership, for $114,000,000.  The Partnership received net proceeds of
approximately  $25,942,000  after  deducting  sale closing costs of  $2,530,000,
property  proration  adjustments  of  $2,195,000,  the  assumption  of the first
mortgage  principal  balance of  $75,600,000  and the  payment of  approximately
$7,733,000  in  subordinated  debt that was  related to the  September  26, 1991
refinancing and modification of the original first mortgage debt.

      As reported in the Partnership's Annual Report on Form 10-K for the fiscal
year ended March 31, 1998,  management believed that the extremely strong Orange
County, California apartment market in which The Lakes is located, combined with
the existence of aggressive apartment buyers having access to an abundant supply
of low cost  capital and seeking  investment  opportunities,  as well as the low
interest rates on The Lakes' secured debt obligations and the dramatic increases
in rental  rates and  operating  efficiencies,  created  value in the Lakes that
might not persist if any one or all of the favorable  conditions were to change.
Management  further  believed  that the  dramatic  rental rate  increases in the
Orange County  market over the past eighteen  months might also be an indication
that the market was  approaching its peak. In light of the above factors and the
impending  expiration,  on  December  15,  1998,  of the  letter of credit  that
guaranteed and secured the principal and interest payments of The Lakes' secured
debt, management believed that this was an opportune time to sell property.

      In connection with the sale, the Partnership  also received  approximately
$2,136,000 as its share of the  property's  working  capital and escrows held in
connection  with the debt.  The total  proceeds  received by the  Partnership of
approximately  $28,078,000 will be included in a special capital distribution of
$28,109,700,  or $675.00 per original $1,000 investment, to be paid on September
9, 1998 to unitholders of record as of August 20, 1998.

      With the sale of The Lakes,  the  Partnership  now has one remaining  real
estate  investment,  the  Harbour  Pointe  Apartments.  This  property  has been
actively marketed for sale and on August 12, 1998, a purchase and sale agreement
was signed with a prospective  buyer.  If a  transaction  closes by November 15,
1998 as  expected,  the  Partnership  will mail a Special  Report by December 1,
1998,   which  is  expected  to  include  a  special  capital   distribution  of
approximately  $70.00 per original $1,000  investment.  This would allow for the
completion of a  liquidation  of the  Partnership  by December 31, 1998. A Final
Report  notifying  Limited  Partners of the  Partnership's  liquidation  is then
expected to be sent to the Limited Partners by December 15, 1998. However, since
the sale of the Harbour Pointe property  remains  contingent  upon,  among other
things, satisfactory completion of the buyer's due diligence and formal approval
by a number of third parties of the assumption of the  tax-exempt  bonds secured
by Harbour Pointe,  there are no assurances that the sale of the final asset and
the liquidation of the Partnership will be completed as planned.

                  (a)  $75,600,000  or such  lower  amount to  reflect  the then
            outstanding  principal  balance  under the  Indenture  Documents (as
            hereinafter  defined) (the "Indenture Balance") by assuming Seller's
            obligations  under (i) that certain  Developer  Note (the "Note") in
            the original  principal amount of $75,600,000  dated as of September

            Rents and Fixture  Filing from Seller to Stewart Title of California
            for the  benefit  of Orange  County  dated as of  September  1, 1991
            recorded in the official  records of Orange  County on September 26,
            1991 as document  91-523544  (the "Deed of Trust) and (iv) all other
            documents  executed in connection  with the Note, the Loan Agreement
            and the Deed of Trust including,  without limitation, the Regulatory
            Agreement (the "Regulatory  Agreement") and other related  documents
            executed in connection  with the foregoing  (collectively,  with the
            Note,  the Loan  Agreement,  the Deed of  Trust  and the  Regulatory
            Agreement, the "Indenture Documents"); and

                  (b) an amount equal to the Purchase  Price less the  Indenture
            Balance by wire transfer of  immediately  available  federal  funds;
            provided,  however,  that the immediately available funds portion of
            the  Purchase  Price  shall be  subject  to  adjustment  to  reflect
            application of the Escrowed Amount and such other adjustments herein
            contained.

      3.2 Within two (2) business  days after the  execution  of this  Agreement
upon the "Opening of Escrow" (as hereinafter  defined),  the Buyer shall deposit
with the Escrow Holder the sum of One Million One Hundred Forty Thousand Dollars
($1,140,000) to be held in an interest bearing account (together with any earned

Agreement.  Subject  only to Buyer's  right to receive a refund of the  Escrowed
Amount (i) on or before the Diligence  Date in  accordance  with Section 5.3 and
Section  6.1,  (ii) in  connection  with a  casualty  or  condemnation  event in
accordance  with Article 8, (iii) in accordance  with Section 10.1,  (iv) in the
event the  Agreement  is  terminated  pursuant to Section 7.5 (a), or (v) in the
event Seller terminates  pursuant to Section 7.5(b) the Escrowed Amount shall be
non-refundable to Buyer.

      3.3  Within  two  (2)  business  days  following  the  execution  of  this
Agreement,  the parties  shall open escrow with Escrow  Holder (the  "Opening of
Escrow").  This Agreement,  when deposited with Escrow Holder,  shall constitute
Escrow  Holder's  escrow  instructions.  The parties  shall execute such further
instructions  as Escrow  Holder may  require in order to clarify  its duties and
responsibilities.  The  escrow  instructions  shall  not  modify  or  amend  the
provisions of this Agreement unless otherwise expressly set forth therein. Buyer
and  Seller  shall  each pay  one-half  of the  escrow  fees,  unless  one party
defaults, in which case the defaulting party shall pay all of the escrow fees.

      3.4 All real estate taxes, assessments, special taxes, special assessments
and any other tax or assessment  attributable to the Property through the Escrow
Closing Date shall be prorated and adjusted as of the Escrow  Closing Date.  All
penalties and interest for  delinquent  taxes and  assessments  shall be paid by
Seller and shall not be  prorated.  If the tax  statements  for the fiscal  year
during which the Escrow Closing Date occurs are not finally determined, then the
tax figures for the immediately prior fiscal year shall be used for the purposes
of prorating taxes on the Escrow Closing Date,  with a further  adjustment to be
made after the Escrow Closing Date as soon as the tax figures are finalized. Any
tax refunds or proceeds  (including  interest thereon) on account of a favorable
determination resulting from a challenge,  protest, appeal or similar proceeding
relating  to taxes and  assessments  relating  to the  Property  (i) for all tax
periods  occurring  prior to the  applicable  tax  period  in which the Close of
Escrow occurs shall be retained by and paid  exclusively  to Seller and (ii) for
the  applicable tax period in which the Close of Escrow occurs shall be prorated
as of the Escrow  Closing  Date  after  reimbursement  to Seller  and Buyer,  as
applicable,  for all fees, costs and expenses (including  reasonable  attorneys'
and consultants' fees) incurred by Seller or Buyer, as applicable, in connection
with such  proceedings such that Seller shall retain and be paid that portion of
such tax refunds or proceeds as is applicable  to the portion of the  applicable
tax period  prior to the Escrow  Closing Date and Buyer shall retain and be paid
that portion of such tax refunds or proceeds as is  applicable to the portion of
the applicable tax period from and after the Escrow Closing Date. Neither Seller
nor Buyer shall  settle any tax protests or  proceedings  in which taxes for the
tax  period  for which  the other  party is  responsible  are being  adjudicated
without the  consent of such  party,  which  consent  shall not be  unreasonably
withheld,  conditioned or delayed. Seller, in its existing proceeding, shall not
reach any  compromise  which  results in a shifting  or deferral of taxes to the
period Buyer is responsible  for. Buyer and Seller shall cooperate in pursuit of
any such  proceedings and in responding to reasonable  requests of the other for
information concerning the status of and otherwise relating to such proceedings;
provided,   however,  that  neither  party  shall  be  obligated  to  incur  any
out-of-pocket  fees,  costs or expenses  in  responding  to the  requests of the
other.  In no event shall any such  proceeding be commenced by Seller  following
the Escrow  Closing  Date  without  Buyer's  prior  written  consent;  provided,
however, that Seller shall be entitled to continue its existing proceeding.

      3.5 Prepaid of amounts under any Contracts (as hereinafter defined), which
are  assigned to Buyer at Close of Escrow  shall be prorated  and adjusted as of
the Escrow Closing Date.

      3.6 At the Close of Escrow,  Buyer will receive a credit to cover the cost
of appliances not yet purchased under the appliance  installation  program which
is more fully  described  on  Schedule E attached  hereto  (i.e.  the program to
provide  refrigerators,  washers and dryers upon tenant  turnover for additional
rent). If, on Escrow Closing Date, there are more than 33 vacant apartment units
(as  determined  on the unit count report  prepared by the  property  management
company and confirmed by Buyer's Director of Property Management),  Seller shall
receive  a credit  as a  reduction  of the  Purchase  Price,  equal to an amount
determined by multiplying the difference between the number of such vacant units
and 33 by $1094.14.

      3.7 Buyer has been  informed  that the  exterior of the Property is in the
process of being repainted.  At the Close of Escrow, the Buyer will also receive
a credit equal to the cost of any  unfinished  exterior  painting work. The cost
will be calculated as of the Escrow  Closing Date based on the amount  remaining
to be paid for the  completion of the painting  contemplated  under the Seller's
painting contract described on Schedule F attached hereto.

      3.8 Interest, escrow accounts, reserves and other charges or credits under
the Indenture  Documents not otherwise  apportioned  pursuant to Section  3.1(c)
shall be prorated and adjusted as of the Escrow Closing Date.

      3.9 The Seller shall cause all meters for electricity,  gas, water,  sewer
or other  utility  usage at the Property to be read on the Escrow  Closing Date,
and the Seller shall pay all charges for such utilities which have accrued on or
prior to the Escrow Closing Date; provided,  however,  that if and to the extent
such charges are paid  directly by tenants,  no such reading or payment shall be
required. If the utility companies are unable or refuse to read meters for which
payment by the Seller is required,  all charges for such utilities to the extent
unpaid shall be prorated and adjusted as of the Escrow Closing Date based on the
most recent bills therefor.  The Seller shall provide notice to the Buyer within
five (5) days of the Escrow  Closing  Date  setting  forth (i)  whether  utility
meters  will be read as of the Escrow  Closing  Date and (ii) a copy of the most
recent bill for any utility  charges which are to be prorated and adjusted as of
the Escrow  Closing Date. If the meters cannot be read as of the Escrow  Closing
Date and,  therefore,  the most  recent bill is used to prorate and adjust as of
the Escrow  Closing Date,  then to the extent that the amount of such prior bill
proves to be more or less than the actual charges for the period in question,  a
further  adjustment  shall be made after the Escrow  Closing Date as soon as the
actual charges for such utilities are available.

      3.10 Collected rents for the then current period;  security deposits which
have not been previously applied by Seller, to the extent in Seller's possession
or control; prepaid rentals; collected or prepaid promotional charges; collected
or prepaid  service  charges;  and all other  collected  or  prepaid  incidental
expenses and charges paid by tenants shall be  apportioned  and full value shall
be adjusted as of the Escrow  Closing Date,  and the net amount  thereof,  if in
favor of Seller,  shall be  credited  to Seller at  Closing of Escrow,  or if in
favor of Buyer,  shall be credited to Buyer at Close of Escrow.  Notwithstanding
anything to the contrary set forth above, but without  duplication,  Buyer shall
receive a credit (a) for security  deposits paid by tenants to Seller which have
not been previously  applied by Seller, and (b) for rents received by Seller and
which are  attributable  to periods after the Closing Date. From and after Close
of Escrow all security  deposits  credited to Buyer shall  thereafter  be deemed
transferred  to Buyer and Buyer shall assume and be solely  responsible  for the
payments of security  deposits (to the extent which Buyer was credited  therefor
at Close of Escrow) to tenants in accordance with the Leases and applicable law.
Seller  shall be  entitled  to retain  and/or  receive a credit for any  utility
deposits and any  deposits  for third  parties  under any of the  Contracts  (as
hereinafter defined).

            3.10.1 Seller shall have no right to collect past due rent or others
      due from tenants after the Close of Escrow. With respect to any delinquent
      rents  collected by Buyer during the first six months  following the Close
      of  Escrow,   such  rents  shall  be  first  applied  to  current   rental
      obligations,  and once current rental  obligations  are  satisfied,  Buyer
      shall deliver to Seller such rentals, net of the reasonable  out-of-pocket
      third party cost of  collection,  received by Buyer from  tenants who owed
      rent  attributable to rental periods other than rents adjusted pursuant to
      Section 3.10 above. Buyer shall have no affirmative  obligation to collect
      such delinquent  rents but shall during such six month period include such
      delinquent amounts on their regular billing correspondence.

            3.10.2 In the event, on the Escrow Closing Date, the precise figures
      necessary  for  any  of the  foregoing  adjustments  are  not  capable  of
      determination,  then, at Buyer's option,  those  adjustments shall be made
      either (i) on the basis of good faith  estimates of Seller and Buyer using
      currently  available  information,  and  final  adjustments  shall be made
      promptly  after precise  figures are  determined or available or (ii) when
      all information for all final adjustments are determined or available.

      3.11 At the Close of Escrow,  the Seller  shall pay the amount due for (a)
one-half (1/2) of any  state or  county  transfer  tax (or  any tax  substituted
therefor,  i.e. the  documentary  transfer tax) imposed in  connection  with the
consummation  of the  transaction  contemplated  hereby and any local  tax,  (b)
recording  charges to record any  documents to clear title;  (c) that portion of
the cost of the Title  Policy  that  would be charged  for a basic CLTA  owner's
policy;  (d) Seller's  attorneys'  fees; (e) all leasing  commissions  due or to
become due  pursuant to any lease of any part of the  Property or any renewal or
extension  right  thereof  in  existence  on  the  date  hereof  whether  or not
exercised;  (f) the actual third party cost of Buyer's termite inspection (up to
a maximum of $10,000);  and (g) one-half (1/2 of the amount of bonuses,  if any,
paid by Buyer to  property  management  personnel  to assure  proper  management
during the pendency of this Agreement (up to a maximum contribution by Seller of
$25,000).

      3.12 At the Close of Escrow, the Buyer shall pay for (a) one-half (1/2) of
any state or county  transfer  tax (or any tax  substituted  therefor,  i.e. the
documentary  transfer tax) imposed in connection  with the  consummation  of the
transaction contemplated hereby and any local tax or mortgage tax; (b) recording
charges to record the grant deed; (c) survey charges for updating the Survey, if
updating is  required by Buyer;  (d) any and all title  insurance  premiums  and
charges  that  exceed the amount  charged by the Title  Company for a basic CLTA
owner's  policy;  (e) any  fees or  charges  incurred  in  connection  with  the
assumption  of  Seller's  obligations  under the  Indenture  Documents;  and (f)
Buyer's attorney's fees and all costs related to the Buyer's due diligence.

      3.13 The provisions of this Article 3 shall survive the Close of Escrow.


                       ARTICLE 4 - PRECLOSING OPERATION

      4.1 A rent  roll  (the  "Rent  Roll")  containing  a list  of all  current
occupants  of the Property is attached  hereto as Schedule C. Upon  execution of
this  Agreement,  Seller shall deliver to Buyer  operating  statements  and rent
rolls for the months of January,  February, March and April, 1998 and the annual
operating  statement  for 1997,  certified to be true and correct to the best of
Seller's  knowledge  together with copies of applicable bank statements  showing
all deposits or revenues  for the  Property  for the same  periods of time.  The
operating statements to be delivered shall show all income, expenses and capital
expenditures  made during the  applicable  periods and the rent rolls shall show
(a) the name and address of each tenant;  (b) the  commencement  and  expiration
dates of each lease;  (c) the amount of rent and/or other charges  billed to and
collected from each tenant for the applicable  periods of time and the totals of
the same;  (d) for each tenant the amount (if any) of  delinquent  rent or other
charges billed which remain unpaid, and the total of the same; (e) the amount of
any security deposit or prepaid rent; and (f) any extension options or rights of
first refusal. Monthly updated rent rolls and operating statements also shall be
delivered to Buyer  promptly  after they are prepared,  through the month of the
Closing. In addition,  Seller shall deliver to Buyer the weekly rent reports for
the  Property  showing the  occupancy,  leasing  activity  and notices to vacate
promptly  after such  reports are prepared by or for Seller from the date hereof
through the Closing.  The leases  listed on the Rent Roll,  together with leases
entered into pursuant to this Article 4 are  collectively  referred to herein as
the "Leases."

      4.2 Seller shall not, after the date hereof; (i) enter into any new Leases
or materially amend or terminate any existing Leases,  except in the same manner
in which  leasing  matters have been  heretofore  conducted,  (ii) enter into or
modify any service  contracts,  operating  agreements,  or easement  agreements,
(iii) alter the zoning classification of the Property, (iv) materially alter any
of the Real Property, or (v) terminate any operating permits without the written
consent of Buyer in any such instance,  which consent shall not be  unreasonably
withheld or delayed.  If Buyer does not notify  Seller in writing of its consent
within five (5) days after written  notice  thereof from Seller,  Buyer shall be
deemed to have denied its consent to such requested action.  Buyer shall specify
its reasons for denying consent upon request of Seller.

      4.3 At all times prior to Close of Escrow,  Seller  shall  continue (a) to
conduct  business  with respect to the Property in the same manner in which said
business  has  been  heretofore   conducted  and  (b)  to  insure  the  Property
substantially as currently insured. Seller shall cause any apartment units which
are vacated at least  fifteen  (15) days prior to the Escrow  Closing Date to be
put in rental ready condition on or before the Escrow Closing Date in accordance
with Seller's current practices, which includes cleaning the apartment, cleaning
or replacing carpet as necessary,  painting, if necessary,  putting the plumbing
and  HVAC in  working  order,  if  necessary,  and if  appliances  have not been
replaced under the appliance replacement program,  replacing  appliances.  Buyer
may inspect such vacated  units within two (2) days prior to the Close of Escrow
to assure compliance with the terms and conditions hereof.

      4.4 Simultaneously with the execution of this Agreement,  Seller shall (i)
provide copies to Buyer of all service, supply, equipment rental, management and
leasing contracts  (collectively,  the "Contracts") affecting the Property which
Seller has in its possession and (ii) instruct the third party property  manager
to make any other files,  documents and information relating to the operation of
the  Property  available  to Buyer for its  review  and  copying  during  normal
business hours at the Property.  Buyer shall, by written notice to Seller, on or
before the expiration of the Diligence Date (as hereafter  defined) identify any
Contracts  which it elects to have  terminated  and  therefore  will not assume;
provided, however, that Buyer may not elect to terminate any Contracts which are
not, by their terms,  terminable or which require  payment of a termination  fee
(unless  Buyer agrees to pay such  termination  fee at Closing).  Buyer shall be
deemed to have elected to take an assignment  of and assume any Contracts  which
are not identified as to be terminated.

      4.5  Simultaneously  with the  execution of this  Agreement,  Seller shall
deliver  to Buyer  (i)  either  (a)  copies  of all  leases  and  amendments  or
extensions  thereto sufficient for Buyer to determine the date and amount of the
last rent  increase to each tenant or (b) a schedule  which shows the amount and
date of the last rent  increase to each tenant and (ii) a schedule of the number
of move-ins  and the number of  move-outs,  delinquent  rents,  if any,  and the
average number of units occupied during each month during calendar year 1997 and
January, February, March and April, 1998.

      4.6  Seller  shall,  prior  to  the  Closing,  remove  the  two  drums  of
unidentified  liquid  located near the emergency  generator at the Real Property
and take the action  identified  in the  Contract  listed on Schedule G attached
hereto  with  respect  to the  monitoring  wells  located  on the Real  Property
identified in the  Environmental  Site  Assessment  Report prepared by Dames and
Moore.

      4.7 Seller  shall,  prior to the  Closing,  at its  expense  (i) cause the
removal of hazardous waste material and (ii) remediate termite  infestation,  if
any,  which is  identified  by Buyer in writing to Seller prior to the Diligence
Date as either  hazardous  waste  material  which is  required  to be removed or
infestation   which  is  required  to  be  remediated,   as  the  case  may  be.
Notwithstanding  the foregoing,  Seller may elect to give Buyer a credit against
the Purchase Price in full  satisfaction of its  obligations  under this Section
4.7. If Seller determines,  in its reasonable  discretion,  that the cost of (i)
such hazardous  waste removal and/or (ii) such termite  infestation  remediation
will exceed $100,000.00, Seller shall have the right to terminate this Agreement
unless Buyer elects, at its option, to pay the amount in excess of $100,000.00.


                   ARTICLE 5 - ACCESS, INSPECTION, DILIGENCE

      5.1 Buyer has received all of the due  diligence  and related items listed
on Schedule 5.1(a) attached hereto.  Buyer has completed its diligence review of
the Property and approves all diligence  matters  pertaining to Property  except
for the (a) items to be delivered to Buyer on execution of this Agreement as set
forth in  Sections  4.1,  4.4,  4.5 and  5.3,  (b) the  investigations  of Buyer
referred  to in Section 5.2 and (c) the items  listed on  Schedule  5.1 (a) (the
"Remaining Diligence Items").

      5.2 Seller agrees that Buyer and its authorized agents or  representatives
shall be entitled to enter upon the Real Property  during normal  business hours
upon advance  written  notice to Seller to make  reasonable  (a)  investigations
regarding  Remaining  Diligence  Items,  and (b) soils,  geologic,  engineering,
environmental  and other tests or studies as Buyer may reasonably  desire.  Such
entry, inspections, tests, and studies shall not damage the Real Property in any
respect.  Seller may require that during any such entry Buyer or its  authorized
agents or  representatives  be accompanied by Seller or its authorized agents or
representatives.  In addition,  Buyer may make such  investigations  of the land
use,  zoning  and other  factors  affecting  the Real  Property  as Buyer  deems
necessary  or  desirable.  Buyer shall keep the  Property  free and clear of any
mechanic's or materialmen's liens arising out of any entry, inspection,  test or
study,  and any entry by Buyer or its  representatives  shall be subject to, and
conducted in accordance with, all applicable laws and the terms of any Leases so
as to avoid any  interference  with the  operations  and  occupancy  of the Real
Property and to avoid any  disturbance  of any of the tenants.  Included in such
investigation  shall be the  right of Buyer  to walk  through  not less  than 77
apartment units with a representative of Seller.  In addition,  Buyer shall have
the right to meet with the applicable  public agencies to gather  information on
the  environmental  condition  of the  Property,  including  the  purpose of the
monitoring  wells  located on the  Property  as  disclosed  in the Dames & Moore
environmental  report  but shall not  disclose  any  information  regarding  the
Property to third parties,  unless  required by law to do so,  without  Seller's
consent.  Seller shall give adequate  notice to the tenants of the Real Property
that Buyer's  termite  inspector is scheduled to inspect the apartment  units on
May 26 and May 27, 1998.

      5.3 To the extent  Seller has any  documents,  studies,  or site  analyses
relating to the Remaining Diligence Items,  including,  without limitation,  the
TRC Environmental Consultants,  Inc., Phase I Environmental Report dated May 30,
1991, Seller agrees to make the same available for review and copying at Buyer's
expense by Buyer or its agents promptly after execution of this Agreement at the
Property during normal business hours.

      Buyer  acknowledges  and agrees that any and all  information,  documents,
surveys,  studies and reports  provided to Buyer are provided for  informational
purposes  only  and  except  as  otherwise  provided  in this  Agreement  do not
constitute representations or warranties of Seller of any kind.

      Buyer shall  complete its review of the  Remaining  Diligence  Items on or
before 5:00 pm New York time on June 4, 1998 (the "Diligence Date"). In order to
accommodate  the  Buyer's  ability  to  conduct  its due  diligence  during  the
abbreviated  time period (i.e.,  from the date of execution of this Agreement to
the Diligence  Date),  Seller agrees to request its  management  company to make
available to Buyer and its representatives in person at the Real Property and by
telephone during normal business hours,  for the purpose of answering  questions
and  providing  information  relating to the Real  Property  and the  operations
thereof, the personnel knowledgeable about such matters,  including Keith Kimmel
and Jan Surratt (while employees of the management company). Notwithstanding any
other term or provision herein to the contrary, in the event that Buyer's review
of the Remaining  Diligence  Items shall reveal any adverse matters with respect
to such Remaining  Diligence Items which are not acceptable to Buyer,  Buyer may
elect,  by  written  notice to  Seller,  received  by  Seller  on or before  the
Diligence Date, not to proceed with this purchase, in which event this Agreement
shall  terminate,  the  Escrowed  Amount  shall be  returned  to Buyer  and this
Agreement shall be null and void without recourse to either party hereto (except
to the extent  such  recourse  arises in  connection  with a  provision  of this
Agreement which is intended to survive termination).

      Buyer has completed its review and approved the Indenture Documents. Buyer
and/or its  representatives  shall meet with officials from the County of Orange
to confirm  that said county will not object to a transfer of the Real  Property
to Buyer and the  Indenture  Documents  will remain  unchanged  upon transfer of
Property  to Buyer  and  delivery  of a  replacement  letter of credit or credit
facility  satisfactory to said county  (provided that Buyer shall be required to
offer a letter of credit from a financial institution with a credit rating equal
to or greater than Buyer's  existing  letter of credit).  In the event Buyer has
not received such  confirmation on or before June 15, 1998,  Buyer may elect, by
written  notice to Seller,  received  by Seller on or before  such date,  not to
proceed with this purchase,  in which event this Agreement shall terminate,  the
Escrowed  Amount shall be returned,  and this  Agreement  shall be null and void
without  recourse to either  party  hereto  (except to the extent such  recourse
arises in  connection  with a provision of this  Agreement  which is intended to
survive termination).

      Buyer  acknowledges that it has had an opportunity to conduct diligence on
the Property and is acquiring the Property in its current condition based on its
diligence. Buyer further acknowledges that except as expressly contained in this
Agreement neither Seller nor its employees,  agents or representatives have made
any  representation  or  warranty  as to the  condition  of the  Property or the
presence  or  absence of any  hazardous  materials  on, in,  under or within the
Property or a portion  thereof which survive  closing  hereunder.  THE PURCHASER
ACKNOWLEDGES AND AGREES THAT THE PROPERTY IS TO BE CONVEYED BY THE SELLER TO THE
PURCHASER  "AS  IS,"  "WITH  ALL  FAULTS,"  AND  SUBSTANTIALLY  IN  ITS  CURRENT
CONDITION.  THE  PURCHASER  FURTHER  ACKNOWLEDGES  AND  AGREES  THAT,  EXCEPT AS
EXPRESSLY CONTAINED HEREIN,  NEITHER THE SELLER NOR ANY AGENT, EMPLOYEE OR OTHER
REPRESENTATIVE   OF  THE  SELLER  (OR   PURPORTED   AGENT,   EMPLOYEE  OR  OTHER
REPRESENTATIVE  OF  THE  SELLER)  HAS  MADE  ANY  GUARANTEE,  REPRESENTATION  OR
WARRANTY,  EXPRESS  OR  IMPLIED  (AND THE  SELLER  SHALL NOT HAVE ANY  LIABILITY
WHATSOEVER) AS TO THE VALUE, USES, HABITABILITY,  CONDITION,  DESIGN, OPERATION,
FINANCIAL CONDITION OR PROSPECTS,  OR FITNESS FOR PURPOSE OR USE OF THE PROPERTY
(OR ANY PART  THEREOF)  OR THE  PROPERTY  INFORMATION,  OR ANY OTHER  GUARANTEE,
REPRESENTATION OR WARRANTY WHATSOEVER,  EXPRESS OR IMPLIED,  WITH RESPECT TO ANY
PORTION OF THE  PROPERTY  (OR ANY PART  THEREOF)  OR THE  PROPERTY  INFORMATION.
FURTHER,  THE SELLER SHALL HAVE NO LIABILITY FOR ANY LATENT,  HIDDEN,  OR PATENT
DEFECT AS TO THE PROPERTY OR THE FAILURE OF THE  PROPERTY,  OR ANY PART THEREOF,
TO COMPLY WITH ANY APPLICABLE LAWS AND REGULATIONS. IN PARTICULAR, THE PURCHASER
ACKNOWLEDGES  AND AGREES THAT THE  "PROPERTY  INFORMATION"  PROVIDED  UNDER THIS
AGREEMENT (AND ANY OTHER  INFORMATION THE PURCHASER MAY HAVE OBTAINED  REGARDING
IN ANY WAY ANY OF THE PROPERTY,  INCLUDING WITHOUT LIMITATION, ITS OPERATIONS OR
ITS FINANCIAL  HISTORY OR PROSPECTS FROM THE SELLER OR ITS AGENTS,  EMPLOYEES OR
OTHER  REPRESENTATIVES)  IS  DELIVERED TO THE  PURCHASER AS A COURTESY,  WITHOUT
REPRESENTATION  OR  WARRANTY  AS TO ITS  ACCURACY  OR  COMPLETENESS,  EXCEPT  AS
EXPRESSLY  OTHERWISE  PROVIDED IN THIS  AGREEMENT  AND NOT AS AN  INDUCEMENT  TO
ACQUIRE THE PROPERTY; THAT NOTHING CONTAINED IN SUCH DELIVERIES SHALL CONSTITUTE
OR BE DEEMED TO BE A GUARANTEE,  REPRESENTATION OR WARRANTY, EXPRESS OR IMPLIED,
IN ANY REGARD AS TO ANY OF THE PROPERTY (EXCEPT AS EXPRESSLY  PROVIDED  HEREIN);
AND THAT THE PURCHASER IS RELYING ONLY UPON THE PROVISIONS OF THIS AGREEMENT AND
ITS OWN INDEPENDENT  ASSESSMENT OF THE PROPERTY AND ITS PROSPECTS IN DETERMINING
WHETHER TO ACQUIRE THE PROPERTY.  The provisions of this paragraph shall survive
Closing.

      5.4 Return of Documents.  If this  Agreement is terminated  for any reason
whatsoever,  Buyer  shall  promptly  deliver  to Seller  all  documents,  plans,
surveys,  contracts,  Leases and the like delivered to Buyer or Buyer's  agents,
representatives  or designees by Seller or Seller's agents,  representatives  or
employees pursuant to this Agreement. In addition,  Buyer shall promptly deliver
to Seller copies of all materials obtained from third parties in connection with
Buyer's  diligence.  Buyer's  obligations under this Section 5.4 shall be deemed
fulfilled if Buyer returns all documents,  plans,  surveys,  contracts,  Leases,
materials  and the  like  as  provided  in  this  Section  5.4  and  provides  a
certificate certifying that all such materials have been returned.

      5.5  Confidentiality.  Each party hereto agrees to maintain in confidence,
and not to  discuss  with or to  disclose  to any  person or entity who is not a
party to this  Agreement,  any material term of this  Agreement or any aspect of
the transactions contemplated hereby, except as provided in this Section. Seller
may publicly disclose the existence of this Agreement provided that the identity
of Buyer and the Purchase  Price is not  disclosed.  Buyer shall not disclose to
anyone other than its  partners  and  financiers  any  information  disclosed by
Seller to Buyer which is not generally  known by the public  regarding  Seller's
operations and/or the Property.  Each party hereto may discuss with and disclose
to its  accountants,  attorneys,  existing or  prospective  lenders,  investment
bankers, underwriters, rating agencies, partners, consultants and other advisors
to the extent such  parties  reasonably  need to know such  information  and are
bound by a confidentiality  obligation identical in all material respects to the
one created by this Section.  Additionally,  each party may discuss and disclose
such matters to the extent  necessary to comply with any requirements of the SEC
or in order to comply  with any law or  interpretation  thereof or court  order.
This provision  shall survive  termination of this Agreement but shall terminate
upon  Close of  Escrow.  Buyer  and  Seller do not  contemplate  issuing a press
release until after the expiration of the Inspection  Period.  Any press release
to be made  regarding  any matter  which is the  subject of the  confidentiality
obligation  created in this Section shall be subject to the reasonable  approval
of Buyer and the Seller, respectively both as to timing and content.

      5.6  Indemnity.  If any  inspection  or test disturbs any of the Property,
Buyer will restore the Property to  substantially  the same condition as existed
prior to any such  inspection  or test.  Buyer shall keep the Property  free and
clear of any liens and will indemnify, defend, and hold Seller harmless from all
losses,  costs and damages  including  reasonable  attorneys'  fees  incurred by
Seller as a result of such entry or investigation by or on behalf of Buyer other
than  loss,  cost or  damage  which  is  discovered  (and  not  caused)  by such
investigation as a result of pre-existing conditions.  This indemnity obligation
of Buyer shall survive the  termination of this Agreement for any reason.  Buyer
shall obtain,  or arrange for its inspecting  consultant to obtain,  and keep in
force, a policy of comprehensive general liability insurance (including coverage
for bodily injury and property  damage) on an  occurrence  basis with a combined
single limit of $1,000,000,  naming Seller as an additional insured. Buyer shall
deliver  evidence of such  insurance  to Seller  prior to the conduct of Buyer's
investigations under Section 5.1.

            ARTICLE 6 - TITLE, SURVEY, CONDITIONS, REPRESENTATIONS
                           AND ASSIGNMENT OF CLAIMS

      6.1 Seller has  provided  Buyer with copies of the most recent ALTA survey
of the Real Property (the "Survey"), and Buyer has obtained a commitment ("Title
Commitment")  for an ALTA Owner's  Extended  Coverage  Policy of Title Insurance
(the "Title  Policy") and has  delivered a copy  thereof to Seller.  Buyer shall
deliver to Seller on or before  5:00 pm New York time on May 28,  1998 a written
list of title exceptions or survey matters  ("Objections")  which are reasonably
objectionable  to Buyer.  On the Escrow  Closing  Date the Title Policy shall be
issued to Buyer by the Title Company in the full amount of the Purchase Price.

      If Seller is unable or  unwilling to agree to cure such  objections  on or
before the  Diligence  Date,  Buyer's  sole remedy  shall be to  terminate  this
Agreement by giving  written notice to Seller on or before the Diligence Date in
which event this Agreement will terminate, the Escrowed Amount shall be returned
to Buyer and this  Agreement  shall be null and void without  recourse to either
party hereto  (except to the extent such recourse  arises in  connection  with a
provision of this Agreement which is intended to survive termination). Buyer may
not object to any exceptions for tenant's rights.  Seller shall not be obligated
to cure any objections.  To enable Seller to convey, Seller may, at the Close of
Escrow use the Purchase Price or any portion  thereof to clear title;  provided,
that all instruments to clear title are either recorded  simultaneously with the
delivery of the deed or arrangements satisfactory to the Escrow Holder have been
made for the  delivery  of such  instruments.  From and  after  the date  hereof
through the Escrow  Closing Date Seller  covenants and agrees not to voluntarily
encumber the Property.

      6.2 On the  Escrow  Closing  Date,  the  Seller  shall  convey by good and
sufficient  grant deed to the Buyer or to the  Buyer's  nominee,  good and clear
record and  marketable  fee  simple  title to all of the Real  Property  and the
Improvements free and clear of all liens, encumbrances,  conditions,  easements,
assessments, restrictions and other conditions, except for the following:

                  (a)   The lien, if any, for real estate taxes not yet due
      and payable;

                  (b) All matters  listed of public  record as of the  effective
      date of Title  Commitment  which  (i) have not been  objected  to and (ii)
      Seller is not  obligated  to cure  and/or  Seller  has not agreed to cure,
      pursuant to Section 6.1 above;

                  (c) All  Leases  disclosed  to Buyer in  writing  prior to the
      expiration of the Inspection Period;

                  (d) All  zoning,  building  and other laws  applicable  to the
      Property; and

                  (e) All matters  which arise after the  effective  date of the
      Title  Commitment  which  are  agreed  upon or  consented  to by  Buyer in
      writing.

                  (f)   The Indenture Documents.

      6.3 Lease  Assignment.  At the Closing,  Seller shall assign the Leases to
Buyer and Buyer shall assume  Seller's  obligations  thereunder and Seller shall
convey the Personal  Property to Buyer by quitclaim  bill of sale,  in each case
Buyer and Seller shall be  responsible  for and indemnify the other with respect
to its period of ownership. Nothing to the contrary contained herein shall alter
the provisions of Article 3 with respect to prorations between Buyer and Seller.

      6.4 Lender.  Promptly  following  the execution of this  Agreement,  Buyer
shall apply and use diligent efforts to obtain any necessary  consents under the
Indenture  Documents to the sale of the Property hereunder and the assumption of
the  Indenture  Documents  by Buyer,  which  consent  Buyer shall  obtain by the
Diligence  Date.  It shall be a condition to Seller's  obligations  to close the
transaction  contemplated hereunder that Seller be released from all obligations
under the Indenture  Documents.  Seller shall cooperate with Buyer in connection
with Buyer's diligent efforts to seek Lender's consent  hereunder.  The terms of
the assumption documents must be reasonably acceptable to Buyer and Seller.

      6.5   Representations and Warranties

            6.5.1 The Seller hereby  represents and warrants to the Buyer to the
best of its  knowledge,  which term shall be limited to the actual  knowledge of

      binding obligation of Seller enforceable against it in accordance with its
      terms.

                  (c) Foreign  Person.  Seller is not a foreign  person and is a
      "United States  Person" as defined in Section  7701(a)(30) of the Internal

      any  governmental  authority  that  Seller is required  to  undertake  any
      remediation activity with respect to hazardous substances on Property.

                  (e) Defects.  Except as  disclosed in the Eckland  Consultants
      Property  Condition  Report or the  independent  roofing roof survey which
      have been delivered by Seller to Buyer or otherwise  disclosed to Buyer in
      writing  or  discovered  by Buyer in its  diligence  with  respect  to the
      Property,   no  material   mechanical  or  structural   defects  exist  in
      improvements which are a part of the Property.

                  (f)  Information.  Seller has made,  or prior to the Diligence
      Date  will  make,  all  information  which  it  has  regarding   hazardous
      substances  located on, in, or beneath the Property available to Buyer and
      Seller has no other  information  regarding the presence or absence of any
      such hazardous substances located on, in, or beneath the Property.

                  (g) Tenant's Claims. Within the last year, except as otherwise
      disclosed in the materials  available at the Property for  inspection,  no
      tenant has made a written claim to Seller that there are other  agreements
      to which it is  entitled  the  benefit  of other  than the Lease with that
      tenant and no tenant has made a written  claim to Seller  that such tenant
      has a defense or offset to rent accruing after the Closing Date.

                  (h) Tenant's Association. No association of tenants, or anyone
      representing  any of the tenants as a group,  has made a written  claim or
      demand  to  Seller  that  has not been  disclosed  by  Seller  to Buyer in
      writing.

            6.5.2 The Buyer hereby  represents  and warrants to the Seller as of
the date of this Agreement as follows:

                  (a) Organization and Power. The Buyer is a general partnership
      organized,  existing and in good  standing  under the laws of the State of
      California  and has the  requisite  power and  authority to enter into and
      perform the terms of this Agreement.

                  (b) Authorization and Execution. The execution and delivery of
      this Agreement and the consummation of the transaction contemplated hereby
      has been duly authorized by all necessary parties and no other proceedings
      on the part of Buyer are necessary in order to permit it to consummate the
      transaction contemplated hereby. This Agreement has been duly executed and
      delivered by Buyer and (assuming  valid  execution and delivery by Seller)
      is a legal, valid and binding  obligation of Buyer enforceable  against it
      in accordance with its terms.

      6.6 The  obligations of the Buyer and Seller to consummate the transaction
contemplated by this Agreement are subject to the representations and warranties
made by the other party to this Agreement being true and correct in all material
respects on and as of the Escrow  Closing Date with the same force and effect as
though  such  representations  and  warranties  had been  made as of the  Escrow
Closing Date.

      7.5   Extension Rights

                  (a)  Buyer.  In the  event  Buyer  is  unable  to  obtain  the
      instruments  referenced in Section  7.3(d) on or before the Escrow Closing
      Date and Buyer is diligently  pursuing the same,  the Escrow  Closing Date
      shall be  extended  on a  day-to-day  basis  until  such  instruments  are
      obtained;   provided,  however  that,  except  as  provided  in  the  next
      grammatical  sentence,  in no  event  shall  the  Escrow  Closing  Date be
      extended  for a period of more than sixty (60) days (the  "Outside  County
      Consent  Date").  Buyer may, on two  occasions,  extend the Outside County
      Consent  Date for a period of up to thirty (30) days by written  notice to
      Seller,  each  accompanied  by an  additional  deposit of $250,000  (which
      payment  shall  be  added  to and  become  part of the  Escrowed  Amount);
      provided,  that in each case,  Buyer is diligently  pursuing such consent,
      Orange  County has not denied  consent  and Buyer has made  available  the
      letter of credit required in Section 5.3.  Throughout the pendency of this
      Agreement,  Buyer shall (i) diligently  pursue consents required under the
      Indenture   Documents  and  (ii)  update  Seller  as  to  the  status  and
      discussions regarding consents required under the Indenture Documents.  In
      the event,  despite Buyer's diligent efforts and Buyer offering the letter
      of credit  required  under Section 5.3,  Buyer is unable to obtain consent
      from Orange County on or before the Outside  County  Consent  Date,  Buyer
      shall have the right not to proceed with the  acquisition,  in which event
      this Agreement shall  terminate,  the Escrowed Amount shall be returned to
      Buyer and this Agreement shall be null and void without recourse to either
      party hereto (except to the extent such recourse arises in connection with
      a provision of this Agreement which is intended to survive termination).

                  (b)  Seller.  In the event  Seller is  unable to  receive  the
      consent of the limited partners of PaineWebber  Development Partners Four,
      Ltd.  to the sale of the  Property on or before the Escrow  Closing  Date,
      Seller shall have the right to extend the Escrow Closing Date to a date no
      later than July 8, 1998 (the "Outside Consent Date").  In the event Seller
      is unable to obtain such  consent on or before the Outside  Consent  Date,
      Seller shall have the right not to proceed with this sale,  in which event
      this Agreement shall  terminate,  the Escrowed Amount shall be returned to
      Buyer and this Agreement shall be null and void without recourse to either
      party hereto (except to the extent such recourse arises in connection with
      a provision of this Agreement which is intended to survive termination).


                     ARTICLE 8 - CASUALTY AND CONDEMNATION

      8.1 If the Improvements are materially damaged or destroyed by fire or any
other casualty and are not substantially  restored to the condition  immediately
prior to such casualty  before the Escrow Closing Date, the Buyer shall have the
following elections:

                  (a) to purchase the Real  Property in its then  condition  and
      pay the Purchase Price, in which event the Seller shall pay over or assign
      to the Buyer as the case may be, on the Escrow  Closing Date,  all amounts
      recovered or  recoverable  by the Seller on account of any  insurance as a
      result of such casualty plus the amount of any applicable deductible, less
      any amounts reasonably expended by the Seller for partial restoration; or

                  (b) if any  portion  of the Real  Property  suffers  damage in
      excess  of  $1,000,000  from fire or other  casualty,  to  terminate  this
      Agreement by giving notice of  termination to the Seller on or before that
      date which is thirty (30) days after the  occurrence  of the fire or other
      casualty or on the Escrow Closing Date,  whichever  occurs first, in which
      event the Escrow  Holder shall  return the  Escrowed  Amount to the Buyer,
      this Agreement  shall terminate and neither the Seller nor the Buyer shall
      have any recourse  against the other  (except to the extent such  recourse
      arises in connection  with a provision of this Agreement which is intended
      to survive termination).

      8.2 If any material  portion of or interest in the Property shall be taken
or is in the process of being  taken by exercise of the power of eminent  domain
or if any governmental authority notifies the Seller prior to the Escrow Closing
Date of its intent to take or acquire any portion of or interest in the Property
(each an "Eminent Domain Taking"),  the Seller shall give notice promptly to the
Buyer of such  event and the Buyer  shall  have the  option  to  terminate  this
Agreement by providing notice to the Seller to such effect on or before the date
which is ten (10) days  from the  Seller's  notice to the Buyer of such  Eminent
Domain Taking or on the Escrow Closing Date,  whichever  occurs first,  in which
event the Escrow  Holder  shall return the  Escrowed  Amount to the Buyer,  this
Agreement shall  terminate,  and neither the Seller nor the Buyer shall have any
recourse  against the other.  If the Buyer does not timely  notify the Seller of
its election to terminate this Agreement,  the Buyer shall purchase the Property
and pay the Purchase Price, and the Seller shall pay over or assign to the Buyer
on delivery of the deed all awards  recovered  or  recoverable  by the Seller on
account of such Eminent Domain Taking,  less any amounts reasonably  expended by
the Seller in obtaining such award.


                       ARTICLE 9 - BROKERAGE COMMISSIONS

      The Buyer  represents  and  warrants  to the Seller that the Buyer has not
dealt with, and is not obligated to pay any fees or commissions to any broker in
connection  with the  transaction  contemplated  by this Agreement  other than a
finder's fee due to William Clark (the "Buyer's  Agent") if the Closing  occurs.
Buyer  shall be  responsible  for  payment of any fees due to Buyer's  Agent and
Seller shall be responsible for any fees due to Seller's Agent, in each case, if
the  transactions  contemplated  herein are consummated.  Seller  represents and
warrants to Buyer that Seller has not used or employed  any broker or brokers in
connection with the negotiation,  execution or consummation of this transaction,
other than Eastdil Realty Company, LLC ("Seller's Agent"). Buyer and Seller each
hereby agree to indemnify,  defend and hold the other  harmless from and against
any and all loss, costs,  claims and expenses (including  reasonable  attorney's
fees)  which  arise as a result of breach of the  foregoing  representation  and
warranty. The indemnification contained in this Article 9 shall survive Close of
Escrow hereunder or termination hereof, as the case may be.


                ARTICLE 10 - DEFAULT, TERMINATION AND REMEDIES

      10.1  In the  event  that  Buyer  has  satisfied  all  of its  obligations
hereunder  and Seller shall have failed in any material  respect  adverse to the
Buyer on the Escrow Closing Date to have performed or has otherwise breached any
of the  covenants and  agreements  contained in this  Agreement  which are to be
performed by the Seller on or before the Escrow  Closing  Date,  the Buyer shall
have the  following  remedies:  (i) the right to take any and all legal  actions
necessary  to compel  the  Seller's  specific  performance  hereunder  (it being
acknowledged  that  damages  at  law  would  be an  inadequate  remedy),  and to
consummate the transaction contemplated by this Agreement in accordance with the
provisions of this  Agreement  (such  conveyance  shall be deemed to satisfy and
waive any  other  remedy)  or (ii) the right to  terminate  this  Agreement  and
receive the Escrowed Amount  whereupon this Agreement  shall  terminate  without
further recourse.

      10.2 NOTWITHSTANDING ANYTHING TO THE CONTRARY CONTAINED IN THIS AGREEMENT,
IF BUYER HAS NOT  TERMINATED  THIS  AGREEMENT (A) ON OR BEFORE THE EXPIRATION OF
THE  DILIGENCE  DATE OR (B) PURSUANT TO ITS RIGHT TO  TERMINATE  UNDER ANY OTHER
PROVISION  CONTAINED IN SECTION 5.3, OR PURSUANT TO SECTIONS 6.1, 8.1(b) OR 10.1
OF THIS  AGREEMENT,  AND IF THE SALE OF THE PROPERTY TO BUYER IS NOT CONSUMMATED
DUE TO BUYER'S  DEFAULT UNDER THE AGREEMENT,  SELLER SHALL BE ENTITLED TO RETAIN
THE  ESCROWED  AMOUNT AS SELLER'S  LIQUIDATED  DAMAGES AS ITS SOLE  REMEDY.  THE
PARTIES  AGREE  THAT IT  WOULD  BE  IMPRACTICABLE  AND  EXTREMELY  DIFFICULT  TO
ASCERTAIN THE ACTUAL DAMAGES  SUFFERED BY SELLER AS A RESULT OF BUYER'S  DEFAULT
UNDER THIS AGREEMENT,  AND THAT UNDER THE CIRCUMSTANCES  EXISTING AS OF THE DATE
OF  THIS  AGREEMENT,  THE  LIQUIDATED  DAMAGES  PROVIDED  FOR  IN  THIS  SECTION
REPRESENTS  A  REASONABLE  ESTIMATE OF THE DAMAGES  WHICH SELLER WILL INCUR AS A
RESULT OF SUCH BUYER'S  DEFAULT AFTER THE EXPIRATION OF THE  INSPECTION  PERIOD,
THE EXTENDED  INSPECTION  PERIOD,  OR THE TITLE RESPONSE PERIOD, AS THE CASE MAY
BE,  PROVIDED,  HOWEVER,  THAT THIS PROVISION SHALL NOT WAIVE OR AFFECT SELLER'S
RIGHTS AND BUYER'S  OBLIGATIONS UNDER SECTIONS 5.5 AND 6.6 AND ARTICLE 9 OF THIS
AGREEMENT.  THE PARTIES  ACKNOWLEDGE THAT THE PAYMENT OF SUCH LIQUIDATED DAMAGES
IS NOT  INTENDED AS A  FORFEITURE  OR PENALTY  WITHIN THE MEANING OF  CALIFORNIA
CIVIL CODE  SECTION  3275 OR 3369,  BUT IS  INTENDED  TO  CONSTITUTE  LIQUIDATED
DAMAGES TO SELLER  PURSUANT TO CALIFORNIA  CIVIL CODE SECTIONS  1671,  1676, AND
1677.

                    --                           --

            10.2.1......As  material  consideration to each party's agreement to
the  liquidated  damages  provisions  stated in Section 10.2,  each party hereby
agrees to waive any and all rights  whatsoever  to contest  the  validity of the
liquidated  damage  provisions  for any reason  whatsoever,  including,  but not
limited to, that such provision was unreasonable under circumstances existing at
the time this Agreement was made.

                          ARTICLE 11 - MISCELLANEOUS

      11.1 The Buyer may only assign or transfer its rights under this Agreement
to an entity  owned,  or  controlled  by Buyer or under  common  control with or
controlling  Buyer provided that (i) no such assignment shall relieve Buyer from
its  obligations  hereunder,  (ii) written  notice thereof is given to Seller at
least ten (10)  business  days prior to the Escrow  Closing  Date and (iii) such
assignment  does not effect the  Buyer's  consents  being  obtained  from Orange
County. The covenants and agreements contained in this Agreement shall extend to

parties to this Agreement.

designate  in a notice  similarly  sent.  Any notice  given by a party to Escrow
Holder shall be  simultaneously  given to the other party. Any notice given by a

shall be simultaneously given to the Escrow Holder.

      11.10 The Escrow Holder has executed this  Agreement  only for the purpose
of  agreeing  to perform the duties  assigned  to it under this  Agreement.  The
Escrow Holder shall deposit the Escrowed Amount in an interest  bearing account.
From the Opening of Escrow,  the Escrow Holder shall, upon receiving a copy of a
notice given by a party in accordance with this Agreement  claiming  entitlement
to all or a portion of the  Escrowed  Amount,  give a notice to the other  party
that such claim of entitlement  has been made. The Escrow Holder shall not cause
or  permit  any  portion  of the  Escrowed  Amount  to be  disbursed  until  the
expiration  of five (5) days of giving  such notice  whereupon,  if the party to
whom  such  notice  was given has not  given  the  Escrow  Holder  notice of its
objection to a disbursement  in accordance  with the claim of  entitlement,  the
Escrow Holder shall cause a disbursement of the Escrowed Amount as requested. If
such party timely objects,  however, the Escrow Holder shall retain the Escrowed
Amount and not  disburse  any portion of the same unless  directed by the mutual
written direction of the parties.  The Escrow Holder shall at all times disburse
the Escrowed  Amount as required in a mutual  written  direction of the parties.

Holder shall retain all deposits pending instructions  mutually agreed to by the
Seller and Buyer. In the event there is no mutual  agreement by Seller and Buyer
for  disbursements,  the Escrow Holder shall hold said deposits  pending a court
order to disburse.  The Escrow Holder may conclusively rely on the authenticity,
validity and  effectiveness  of any writing  delivered to it, and Escrow  Holder
shall not be obligated to make any  investigation  or  determination,  except as
provided in the case of disputes as to the truth and accuracy of any information
contained therein.  Buyer and Seller agree to defend,  indemnify and hold Escrow
Holder harmless from any liabilities, suits, claims, or expenses arising from or
out of or in connection  with Escrow  Holder's acts or failure to act hereunder,
unless caused or created as a result of Escrow Holder's  negligence,  and Escrow
Holder  shall be  entitled  to  reimbursement  by Buyer  and/or  Seller  for all
reasonable  costs  and  expenses  incurred  in the  performance  of  its  duties
hereunder  including,   without  limitation,   all  out-of-pocket  expenses  and
reasonable  attorneys fees of counsel retained by Escrow Holder.  Any such costs
and expenses not paid by the parties after billing and supporting  documentation
by Escrow  Holder may be paid by Escrow  Holder out of the Escrowed  Amount.  If
there is a settlement by Buyer and Seller prior to a court order,  the Buyer and
Seller  will  share  equally in the  expenses  incurred  by the  Escrow  Holder.
Otherwise,  the  non-prevailing  party shall assume full  responsibility for the
Escrow Holder's expenses.  Escrow Holder is not required to advance or expend or
risk its own funds or otherwise  incur personal  liability in performance of its
duties hereunder and it may require advancement of funds by the parties.

      11.12 Time is expressly declared to be of the essence of this Agreement.

      11.13 The  obligations  of Seller  hereunder  shall be binding only on the
Property  and neither  the Buyer nor anyone  claiming  by,  through or under the
Buyer shall be entitled to obtain any judgment  extending  liability  beyond the
Property or creating personal liability on the part of the officers,  directors,
shareholders,  partners  or agents of  Seller  or any of their  successors.  The
obligations of Buyer  hereunder shall be binding only on the assets of Buyer and
neither the Seller nor anyone  claiming by, through or under the Seller shall be
entitled to obtain any judgment creating  personal  liability on the part of the
partners, officers,  shareholders, or agents of Buyer or any of their successors
or any affiliated entities.

      11.14 No waiver of any  provisions  of this  Agreement  shall be deemed or
shall constitute,  a waiver of any other provision,  whether or not similar, nor
shall any waiver  constitute  a  continuing  waiver.  No waiver shall be binding
unless executed in writing by the party making the waiver.

      11.15 Each party, at the request of the other, shall execute,  acknowledge
(if appropriate) and deliver whatever  additional  documents,  and do such other
additional acts, as may be reasonably required (in each case, without additional
liability and subject to reasonable  approval of counsel) in order to accomplish
the intent and purposes of this Agreement.

                                 MAY 22, 1998

          ---------------------------------------------------------


      THIS FIRST AMENDMENT  ("FIRST  AMENDMENT") is entered into this 4th day of

                   (d)  status report on all residents in process of eviction;
                   (e)  original Contracts;

                        files for only the employees Buyer's  management company
                        will  retain,  which shall  contain,  as a minimum as to
                        each such employee,  (i) hiring date,  (ii) salary,  and
                        (iii) actual title of the employee;
                   (g)  original (or copies,  if originals are not available) of

Northcott.

            1.4 Seller shall instruct its management company to deliver to Buyer
on or before June 8, the following additional items:

                   (a)  lien waiver and release from WM Sales Company, Inc.;
                   (b)  copy of the written agreement with apartments.com;
                   (c)  a schedule of locations  and dates of  installations  of
                        all telephone installations by Pacific Bell;
                   (d)  a copy  of  the  reverse  side  of  the  agreement  with

proper  abandonment  of the three (3) additional  monitoring  wells and nine (9)
piezometers located on the Real Property and identified in the PEER Consultants,
P.C.  report  dated May 26, 1998 a copy of which is  attached  hereto as Exhibit
"A".

            1.6 From June 4, 1998 until the Closing,  Buyer shall have the right
to approve in a timely  manner after  written  notice from Seller (a) any leases
where the rental amount is less than those set forth on the rent schedule  which
Seller has delivered to Buyer, and (b) all move-in specials or concessions which
are not included on the rent schedule  which Seller has delivered to Buyer.  Any
such leases or  concessions  not  disapproved by Buyer within three (3) business
days after written request is received shall be deemed approved by Buyer. Seller
shall cause Keith  Kimmel to conduct  weekly  telephone  calls until the Closing
with Buyer's designee regarding leasing and occupancy issues and activities.

            1.7 Seller shall  continue to expend the  scheduled  $5,600  monthly
amount for advertising the rental opportunities at the Real Property, and Seller
shall send to Buyer copies of the "tear" sheets and invoices for all advertising
expenditures made from the date of the Agreement through the Closing.

            1.8 At the  Closing,  Buyer  shall be  entitled  to a credit of Five
Hundred Thirty Thousand Dollars ($530,000.00) for roofing replacement.

      2. The  following  subparagraphs  are  hereby  added to  Section  6.5.1 of
Article 6 of the Agreement:

            2.1 Maintenance  Agreement  Obligations.  Seller has not, within the
last  12  months,  received  written  notice  that  it  has  not  performed  its
maintenance  and other  obligations or that Seller is in default under the terms
of the  Declaration  Establishing  Easements and Maintenance  Obligations  dated
August 31,1984 which is referred to in item 3. of the Title Commitment.

            2.2 No Condominium  Sales.  No  condominium  units have been sold or
transferred,  nor has Seller  entered  into any  contract  to sell,  transfer or
convey any of the  condominium  units (except for the Agreement)  referred to in
the Condominium  Plan recorded March 12, 1998 and referred to in item 20. of the
Title Commitment.

            2.3  Monitoring  Wells.  (i) The prior  dispute  relating to a soils
compaction issue has been settled,  and (ii) Seller is not aware of any soils or
related  structural  or  foundation  problems  that have  developed  at the Real
Property since the settlement and dismissal of said litigation.

      3. The 4th  paragraph  of Section 5.3 of the  Agreement  is deleted in its
entirety and replaced with the following:

            Buyer has completed its review and approved the Indenture Documents.
Buyer and/or its  representatives  shall meet with  officials from the County of
Orange to confirm  that said  county  will not object to a transfer  of the Real
Property  to Buyer  and the  Indenture  Documents  will  remain  unchanged  upon
transfer of the Property to Buyer and delivery of a replacement letter of credit
or credit  facility  satisfactory  to said county  (provided that Buyer shall be
required to offer a letter of credit from a financial  institution with a credit
rating  equal to or greater  than  Seller's  existing  letter of  credit,  which
evidence   may  include  a  letter  from   Buyer's   counsel   confirming   such
creditworthiness).  In the event Buyer has not received such  confirmation on or
before June 15, 1998, Buyer may elect, by written notice to Seller,  received by
Seller on or before such date, not to proceed with this purchase, in which event
this Agreement shall terminate,  the Escrowed Amount shall be returned, and this
Agreement shall be null and void without recourse to either party hereto (except
to the extent  such  recourse  arises in  connection  with a  provision  of this
Agreement which is intended to survive termination).  Buyer shall deliver copies
of all  material  submitted  to the  County  of  Orange  with  respect  to  such
replacement letter of credit and the Indenture  Documents during the pendency of
this Agreement.

      4. Except as expressly modified by this First Amendment,  all of the other
terms,  covenants and conditions contained in the Agreement shall remain in full
force and effect.

      NOW,  THEREFORE,  in  consideration  of the  consent  of the County to the
transfer of the Project to the New Owner,  the parties  hereto  hereby  agree as
follows:

      1.    Assumption of Bond Documents.

            1.1 The Owner  hereby  assigns  to the New Owner all of its  rights,
duties  and  obligations  under  the Bond  Documents,  and,  from and  after the
Effective  Date,  the New Owner  unconditionally  accepts  and  assumes all such
rights,  duties and obligations and agrees to perform all such  obligations from
and after the Effective Date in accordance with the terms of the Bond Documents.

            1.2  The  New  Owner  hereby   represents   and  warrants  that  the
performance  of the  New  Owner's  obligations  under  the  Bond  Documents  and
compliance  with the  terms  thereof  will not  result in a breach of any of the
terms and  provisions of, or constitute a default  under,  any contract,  lease,
indenture,  deposit  agreement,  mortgage,  deed of trust or other  agreement to
which the New Owner is a party or by which it is bound.

            1.3 The New Owner  acknowledges  that it has  received  and reviewed
copies of all of the Bond Documents,  and all other  documents,  instruments and
agreements  related  to the  Bonds,  and  that it  understands  the  provisions,
contents  and  effect  thereof.  As  provided  in  Section  2.2(i)  of the  Loan
Agreement,  the New  Owner  acknowledges  that it has read and  understands  the
provisions  of the  Indenture  and agrees to be bound by the terms  thereof that
relate to the owner of the Project from and after the  Effective  Date,  and, in
particular,  the  terms of  Section  504 of the  Indenture,  from and  after the
Effective Date. The Administrator (as defined in the  Administration  Agreement)
is independent  from and not under the domination of the New Owner or any entity
comprising the New Owner,  does not have any interest or business  relationship,
direct or indirect,  in the New Owner or any entity comprising the New Owner nor
does the New  Owner  have any  interest  or  business  relationship,  direct  or
indirect, with the Administrator.

            1.4 The County hereby consents to the transfer of the Project to the
New Owner,  and the County and the Trustee  acknowledge the  satisfaction of the
conditions to transfer set forth in Section 10 of the Regulatory Agreement.  The
County and the Trustee  hereby  release the Owner from any  liability  under the
Bond Documents  arising from and after the Effective  Date,  including,  without
limitation,  the  Owner's  liabilities  pursuant  to  Section  6.8 of  the  Loan
Agreement;  provided,  however,  the  Owner  shall  be fully  released  from its
obligation to pay  principal  and interest  with respect to the  Developer  Note
whether or not such obligation arose prior to the Effective Date.

      2.    No Defaults.

            2.1 The Owner represents,  warrants and covenants for the benefit of
the County and the  Trustee  only and not for the  benefit of the New Owner that
(i) no  event  of  default  or  default  (as  such  terms  are  used in the Bond
Documents)  has  occurred  under the Bond  Documents,  and no event has occurred
which,  with the giving of notice or passage of time, or both,  would constitute
an event of default or default under the Bond Documents,  (ii) all amounts owing
under the Bond Documents are current and (iii) it has not received any notice of
default relating to amounts owing under the Bond Documents.

            2.2 The Owner expressly represents for the benefit of the County and
the  Trustee  only and not for the  benefit  of the New Owner  that at all times
during the period of its  ownership of the Project,  not less than 20 percent of
the units in the Project have been  continuously  occupied by or held  available
for  occupancy by Lower Income  Tenants at  Affordable  Rents (as such terms are
defined in the Regulatory Agreement),  and at least half of such units have been
occupied  by or held  available  for  occupancy  by Very Low  Income  Tenants at
Affordable  Rents (as such terms are defined in the  Regulatory  Agreement),  as
required by Section 4 of the Regulatory Agreement.

            2.3 The  Trustee represents  that (i) no event of default or default
(as such terms are defined in the Bond  Documents)  has occurred  under the Bond
Documents, and no event has occurred which, with the giving of notice or passage
of time, or both, would constitute an event of default or default under the Bond
Documents,  (ii) all  amounts  owing  under the Bond  Documents  payable  to the
Trustee  are current  and (iii) the  Trustee has not given any notice of default
relating to amounts owing under the Bond Documents.

            2.4 The County  represents that it has received no information which
would  cause it to believe  that an event of default or a default (as such terms
are defined in the Bond  Documents) has occurred or with the giving of notice or
passage of time, or both, would occur under the Bond Documents.

      3.    Amendment to Regulatory Agreement.

            3.1 The parties hereto agree that the Qualified Project Period shall
be amended to provide that the Qualified  Project Period shall expire no earlier
than December 1, 2006.

      4.  Indemnity.  The Casden  Operating  Partnership  (including its general
partner)  agrees to guarantee  the New Owner's  obligations,  from and after the
Effective  Date for only claims that are caused by actions or inactions from and
after the Effective Date, under Section 6.8 of the Loan Agreement.  In the event
a request for payment by the County or the Trustee under Section 6.8 of the Loan
Agreement is not honored  within  thirty (30) days of such  request,  The Casden
Operating Partnership will pay the amount due within thirty (30) days of receipt
of the request for  payment.  All  requests  for payment  shall be  submitted to
Casden at 9090 Wilshire Boulevard, Third Floor, Beverly Hills, California 90211,
Attention: Henry C. Casden.

      5.    Miscellaneous.

            5.1 The New Owner agrees to pay all costs and  expenses  incurred by
the  County  and the  Trustee,  including  legal  fees  and  expenses  of  their
respective  counsel,  in connection  with the transfer of the Project to the New
Owner and in connection  with the  associated  assumptions of the Bond Documents
and related actions.

            5.2 All  correspondence  and  notices  given or required to be given
under the Bond Documents may be addressed to the New Owner as follows:

      Casden Lakes LP
      c/o Casden Properties
      9090 Wilshire Boulevard, Third Floor
      Beverly Hills, California  90211
      Attention:  Henry C. Casden

      5.3 Except as  expressly  set forth  herein,  the Bond  Documents  are not
altered,  amended or modified by reason of this  Assumption  Agreement,  and the
Bond  Documents  shall  remain in full force and effect and their  validity  and
enforceability are hereby ratified and confirmed.

      5.4 This  Assumption  Agreement  shall be binding upon the parties hereto,
and upon their successors in interest and assigns.

      5.5 This  Assumption  Agreement may be executed in  counterparts,  each of
which shall be deemed an original upon execution.

      5.6  This  Assumption   Agreement  shall  be  effective  on  the  date  of
recordation  in the Official  Records of this  Assumption  Agreement  and of the
grant  deed  transferring  ownership  of the  Project  to  the  New  Owner  (the
