ITEM 2 - Disposition of Assets

Martin Sunnyvale Research and Development Center, Sunnyvale, California

Disposition Date - May 29, 1998

      On May 29, 1998,  Paine Webber  Qualified Plan Property Fund Four, LP (the
"Partnership") sold its wholly-owned  investment property,  the Martin Sunnyvale
Research  and  Development  Center,  located  in  Sunnyvale,  California,  to an
unrelated third party for $5,125,000.  After closing costs,  expense  prorations
and  adjustments,   the  Partnership  realized  net  proceeds  of  approximately
$4,938,000.  As a  result  of the  sale of the  Martin  Sunnyvale  Research  and
Development Center, a Special Distribution will be made on June 15, 1998 to unit
holders of record as of May 29, 1998. The Special  Distribution will include the
net proceeds  from the sale of the Martin  Sunnyvale  Research  and  Development
Center  in the  amount  of $109 per  original  $1,000  investment,  or $5.45 per
original $50 unit.

      As previously reported,  during fiscal 1997 the Partnership had contracted
with a  national  real  estate  firm with a strong  background  in  selling  R&D
buildings in the Silicon Valley area to market the Martin Sunnyvale property for
sale. As a result of these marketing efforts,  the Partnership  received several
offers  from  qualified  third-party  buyers  to  acquire  the  property.  After
reviewing  the  offers,  the  Partnership  accepted  an offer  from one of these
potential  buyers and  negotiated  and  executed a purchase  and sale  agreement
during  the first  quarter  of fiscal  1998.  The sale  remained  subject to the
satisfactory  completion of the buyer's due diligence  which was scheduled to be
completed  in December  1997.  At the  conclusion  of the buyer's due  diligence
period,  the offer to purchase the property was  withdrawn.  In early 1998,  the
Partnership  and its marketing  agent  decided to refocus  attention on a select
group of potential  investors that had expressed  previous interest in acquiring
the  property.  These  potential  buyers were  contacted  which  resulted in the
receipt of two written  offers.  Subsequently,  one of these offers was selected
and negotiations on a purchase and sale agreement were successfully completed. A
purchase and sale  agreement  was executed by the  Partnership  and the eventual
buyer on March 11, 1998.  The  Partnership  granted the eventual  buyer  several
extensions  of the due  diligence  period in return for  certain  non-refundable
deposits prior to the final closing of the transaction on May 29, 1998.

      Subsequent to the sale of the Martin Sunnyvale property, the Partnership's
only remaining real estate asset is the wholly-owned  Bell Forge Square Shopping
Center. As discussed  further in the Partnership's  most recent quarterly report
on Form 10-Q, this property is in the process of being actively  marketed with a
goal of completing a sale and a liquidation of the Partnership  prior to the end
of  calendar  1998.  There  are no  assurances,  however,  that  the sale of the
remaining asset and the liquidation of the Partnership  will be completed within
this time frame.

                                PURCHASE AND SALE

      2.1 In  consideration  of the  undertakings  and mutual  covenants  of the
parties  set  forth  in  this  Agreement,   and  for  other  good  and  valuable
consideration,   the  receipt  and  legal   sufficiency   of  which  are  hereby
acknowledged,  the Seller  hereby  agrees to sell and convey the Property to the
Buyer or its nominee  and the Buyer  hereby  agrees to buy and pay the  Purchase
Price for the Property on the terms and conditions contained herein.

                          ARTICLE ESCROW INSTRUCTIONS;
                      PURCHASE PRICE; DEPOSIT; ADJUSTMENTS

      3.1 The Purchase  Price shall be as specified in Article 1 above and shall
be paid on the Escrow Closing Date (as hereinafter  defined) by wire transfer of
immediately   available   federal  funds,   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 Hundred Thousand Dollars  ($100,000) to be
held in an interest  bearing  account  (together  with any earned  interest  the
"Escrowed Amount") to secure the Buyer's obligations under this Agreement.

      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 the Purchase and Sale  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 unless
such items are paid directly by tenants to the applicable taxing  authority,  in
which case no adjustment or proration  shall be made for the items paid directly
by the  tenants.  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. 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  or past due  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 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.

      3.7 Collected rents for the then current period;  security  deposits which
have  not  been  previously  applied  by  Seller,  to  the  extent  in  Seller's
possession;  prepaid  rentals;  collected  or prepaid  common  area  maintenance
charges;  collected or prepaid promotional charges; collected or prepaid service
charges;  collected or prepaid tax 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.
From and after  Close of Escrow all  security  deposits  credited to Buyer shall
thereafter  be  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).

            3.7.1 All rentals and other  tenant  charges  payable in arrears and
      uncollected and all other uncollected  rents  (including,  but not limited
      to, percentage rents,  common area maintenance charges and real estate tax
      charge  annual  adjustments  thereto)  for the  current  and prior  rental
      periods,  less the  reasonable  expenses of collection  thereof,  shall be
      apportioned  (if and when collected by either party);  provided,  however,
      that Buyer shall proceed in a commercially  reasonable  manner  consistent
      with Buyer's  customary  practice for tenants owing past due rent to it to
      collect such  uncollected  rents from existing  tenants listed on the rent
      roll;  provided that Buyer shall not be obligated to commence suit against
      any Tenant and Buyer shall first apply rents subsequently received to rent
      due and owing for rental  periods  accruing after the Escrow Closing Date.
      Buyer  shall not settle or release (i) Tenants  from any  obligations  for
      such  uncollected  rents or (ii) rights under any claims listed in Section
      3.7.2 below, in each case, without Seller's prior written approval.  Buyer
      shall provide Seller with written evidence of its collection efforts, such
      evidence shall include,  but not be limited to providing copies of letters
      and invoices to tenants, copies of reports regarding follow-up efforts and
      cash  receipts  and aged  delinquency  reports.  Buyer shall  provide such
      written  evidence of its  collection  efforts  within fifteen (15) days of
      demand  therefor  provided  that Seller may request such  evidence no more
      than on a quarterly basis. Seller shall agree not to commence suit against
      tenants  listed on the rent roll for  obligations  owed to it unless Buyer
      fails to fulfill its obligations under this Section 3.7.1.

            3.7.2  Subject to Section 6.6 below,  Seller shall retain all rights
      to all refunds,  receivables, past due rent and claims, including, but not
      limited  to,  termination  fees or  damages  from all  former  tenants  or
      occupants of the Property which are not listed on the Rent Roll, causes of
      action and rights of  reimbursement  from third parties,  bonds,  accounts
      receivable and any other claims for payments Seller may have to the extent
      arising or relating to the period prior to the Close of Escrow.

            3.7.3 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.

      3.8 At the Close of Escrow,  the  Seller  shall pay the amount due for (a)
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 (the "Transfer Tax"); (b) recording charges to
record any documents to clear title; (c) all title insurance  charges to provide
Buyer with a Title Commitment as hereinafter  defined;  (d) Seller's  attorneys'
fees; and (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.

      3.9 At the Close of Escrow,  the Buyer  shall pay for (a) any local tax or
mortgage tax other than the Transfer  Tax; (b)  recording  charges to record the
grant deed; (c) survey  charges;  (d) any and all title  insurance  premiums and
charges  including but not limited to charges for any extended coverage or title
endorsements;  and (e)  Buyer's  attorney's  fees and all costs  related  to the
Buyer's due diligence.

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

                                    ARTICLE 3
                              PRECLOSING OPERATION

            A Rent Roll certified by Seller (the "Rent Roll")  containing a list
of all current  occupants of the Property is attached  hereto as Schedule C. 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."

            Seller  shall  not,  after the date  hereof;  (i) enter into any new
Leases or materially amend or terminate any existing Leases,  (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
Improvements, 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.

            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  within  five (5) days  after  the  execution  of this
Agreement  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 shall  promptly  instruct the
third party property  manager to make all such Contracts  available to Buyer for
its  review.  Buyer  shall,  by  written  notice to  Seller,  on or  before  the
expiration of the Inspection  Period  identify any Contracts  which it elects to
have  assigned to it and  therefore  will assume.  Buyer shall be deemed to have
elected not to assume any Contracts  which are not  identified as to be assigned
and assumed.  Seller shall  terminate any Contracts at Close of Escrow which are
not  identified  by Buyer as  specified  in this  Section as to be assigned  and
assumed at Close of Escrow.

            Seller  shall  use  diligent   efforts  to  obtain  tenant  estoppel
certificates  for each Tenant of the  building on the Property on or before five
(5) days prior to the expiration of the Inspection  Period.  The tenant estoppel
certificates  shall be in the form  attached  hereto  as  Schedule  D.  Seller's
failure to provide tenant estoppel  certificates  shall not constitute a default
under  this   Agreement.   If  Seller  fails  to  provide  the  tenant  estoppel
certificates  within the time period set forth,  Buyer's  sole remedy will be to
elect not to proceed with the  transaction  by giving  written notice before the
expiration of the Inspection Period.  Upon such notice the Escrowed Amount shall
be returned to Buyer and this  Agreement  shall be  terminated  without  further
recourse  (except  to the  extent  such  recourse  arises in  connection  with a
provision of this  Agreement  which is intended to survive  termination).  If no
written notice is received by Seller by the expiration of the Inspection Period,
the  Escrowed  Amount  shall  be  non-refundable  for any  reason  and  shall be
liquidated damages as set forth in Section 10.2.

                                    ARTICLE 4
                          ACCESS, INSPECTION, DILIGENCE

            Buyer may,  during the  "Inspection  Period" as  hereafter  defined,

operations and financial  condition of the Property,  environmental  remediation
insurance  (if  any),  and the  transferability  of any  relevant  environmental
permits,  indemnifications,  or covenants.  Buyer may not conduct destructive or
invasive testing,  drilling or boring.  Buyer's  inspection rights shall include
access, upon Seller's written consent, which shall not be unreasonably withheld,
and in each case Buyer must be accompanied by a representative of Seller, to all
of Seller's personnel,  agents, engineers,  brokers, property managers, tenants,
vendors,   consultants  and  contractors   familiar  with  the  Property.   Such
representatives will be made reasonably available with at least 24 hours advance
written notice by the Buyer.

            Seller  shall  make  available  to  Buyer  for  Buyer's  review  and
inspection,  and in each case to the extent the  materials  are in the  Seller's
possession  or  control,  copies of all  leases,  contracts,  agreements,  data,

reports),  title surveys,  plans and specifications,  certificates of occupancy,
operating  statements  for the  month of the  date  hereof  and the  last  three
year-ends,  itemized  capital  expenditures  over  the past  thirty-six  months,

and easements,  insurance policies and claims history,  guaranties,  warranties,
governmental  agency  orders,  certificates  of  insurance,  past,  pending  and

Seller shall  provide all relevant  information  regarding its liability for the
environmental contaminants,  including, but not withstanding, all correspondence
between the Regional Water Quality Control Board and the Seller,  as well as all
correspondence  by Eaton  Corporation  and Signetics  Corporation  regarding the
environmental   liabilities,   indemnifications,   or   covenants   by  the  two
aforementioned corporations.  Buyer may make copies of the above at Buyer's sole
cost and expense.  Seller shall cause the property manager to provide Buyer with
a complete  and  accurate  rent roll for the  Property  which shall  include the
following information,  as of the last full month preceding this Agreement:  the
names of all  tenants  and their  corresponding  suite  number,  the term of all
leases,  rental amounts  including prepaid rents,  delinquent  rents,  extension
options,  security and other deposits, rent concessions,  and tenant improvement
allowances, if any.

      Seller  makes no  representation  or  warranty  whatsoever  regarding  the
existence or  availability of the foregoing and Seller shall not be obligated to
create or obtain any of the  foregoing  which are not in existence and available
to Seller.  Buyer  acknowledges and agrees that, except as otherwise provided in
this Agreement, any and all information, documents, surveys, studies and reports
provided  to Buyer  are  provided  for  informational  purposes  only and do not
constitute representations or warranties of Seller of any kind.

     The Buyer shall have the right to promptly commence and actively pursue its
due  diligence  on the  Property as provided  for in Sections 5.1 and 5.2 above.
Buyer shall  complete its due  diligence no later than thirty (30) days from the
date of this Agreement (the "Inspection  Period"). In the event that Buyer's due
diligence  shall reveal any matters which are not acceptable to Buyer in Buyer's
sole and absolute  discretion for any reason or for no reason,  Buyer may elect,
by written notice to Seller,  received by Seller on or before  expiration of the
Inspection  Period,  not to  proceed  with this  purchase,  in which  event this
Agreement  shall  terminate,  the Escrowed Amount shall be returned to the 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).  In the event Buyer
does not terminate  this Agreement on or before the expiration of the Inspection
Period, the Escrowed Amount shall become  nonrefundable for any reason and shall
be liquidated damages as set forth in Section 10.2.

      Buyer  acknowledges  that it  will  have  had an  opportunity  to  conduct
diligence on the Property and will acquire the Property in its current condition
based on its diligence.  Buyer further  acknowledges that 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  Close  of  Escrow  hereunder  except  as  expressly  provided  in  this
Agreement.  Seller has disclosed, and Buyer acknowledges disclosure of, Seller's
knowledge regarding the release of hazardous  substances on the Property that is
subject  to  California  Regional  Water  Quality  Control  Board  Site Clean Up
Requirements  Order No. 95-210 dated October 18, 1995 (the  "Order").  THE BUYER
ACKNOWLEDGES AND AGREES THAT THE PROPERTY IS TO BE CONVEYED BY THE SELLER TO THE
BUYER "AS IS," "WITH ALL FAULTS," AND  SUBSTANTIALLY  IN ITS CURRENT  CONDITION.
THE BUYER FURTHER ACKNOWLEDGES AND AGREES THAT, EXCEPT AS EXPRESSLY CONTAINED IN
THIS   AGREEMENT,   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 NOT PREPARED BY SELLER, 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  NOT  PREPARED  BY SELLER  EXCEPT  AS  EXPRESSLY  SET FORTH  HEREIN.
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 BUYER
ACKNOWLEDGES  AND AGREES THAT THE  "PROPERTY  INFORMATION"  PROVIDED  UNDER THIS
AGREEMENT WHICH WAS NOT PREPARED BY SELLER (AND ANY OTHER  INFORMATION THE BUYER
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 BUT NOT INCLUDING INFORMATION
PREPARED  BY  SELLER)  IS  DELIVERED  TO  THE  BUYER  AS  A  COURTESY,   WITHOUT
REPRESENTATION  OR  WARRANTY  AS TO ITS  ACCURACY  OR  COMPLETENESS  (EXCEPT  AS
EXPRESSLY  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  IN  THIS
AGREEMENT);  AND THAT THE  BUYER 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  EXCEPT  THAT BUYER  SHALL BE
ENTITLED TO RELY ON THE  REPRESENTATIONS  AND WARRANTIES  EXPRESSLY SET FORTH IN
THIS AGREEMENT. The provisions of this paragraph shall survive Close of Escrow.

            Buyer shall  provide  Seller  with a copy of the  Buyer's  financial
statements  over the past three years before the  expiration  of the  Inspection
Period. Seller shall have the right to terminate the Purchase and Sale Agreement
before the expiration of the  Inspection  Period if the Seller is not satisfied.
The provision of such information shall not be deemed to be an acknowledgment on
the part of either  such  entity to  undertake  or be liable for any  obligation
under this Agreement.

            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
if Seller is willing to reimburse Buyer for bona fide third-party  out-of-pocket
costs and expenses actually  incurred in the preparation of such materials.  The
return of the Escrowed  Amount to Buyer under this Agreement shall be contingent
upon Buyer's  fulfillment  of the  obligations  under this Section 5.5.  Buyer's
obligations  under this Section 5.5 shall be deemed  fulfilled if Buyer  returns
all documents,  plans,  surveys,  contracts,  Leases,  materials and the like as
provided in this Section 5.5 and provides a certificate certifying that all such
materials have been returned.

            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 and Title  Response  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.

            If any  inspection  or  test  conducted  by or on  behalf  of  Buyer
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.

            Seller's  obligation to sell the Property shall be contingent  upon,
(i) the  execution of a joint  letter,  substantially  in the form of Schedule E
requesting (a) that the Regional Water Quality  Control Board  substitute  Buyer
for Seller as a "secondarily liable party" or so-called  "secondary  discharger"
on the  Order  (the  "Substitution")  upon  the  Close of  Escrow,  (b) that the
Regional  Water  Quality  Control  Board staff prepare an amendment to the Order
providing  for the  Substitution  and allow the Buyer and  Seller to review  and
approve  the  amendment  before  the  Escrow  Closing  Date,  and (c)  that  the
Substitution not be effective until Close of Escrow, (the "Substitution Letter")
and (ii) the  submission  of the executed  Substitution  Letter,  along with any
other  documents,  applications or fees required,  to the Regional Water Quality
Control  Board  on the  first  business  day  following  the  expiration  of the
Inspection  Period.  Seller and Buyer agree to appear before the Regional  Water
Quality Control Board in connection with the Substitution  Letter if required to
do  so.  Buyer  will  execute  any  license  or  access  agreements  with  Eaton
Corporation and Signetics Corporation, if required by the Regional Water Quality
Control Board in order to  effectuate  the  Substitution.  Buyer and Seller will
cooperate fully and use their best efforts to effectuate the  Substitution.  The
obligations under this Section shall survive the Close of Escrow.

                                    ARTICLE 5
  TITLE, SURVEY, CONDITIONS, REPRESENTATIONS AND ASSIGNMENT OF CLAIMS

            Within  five (5) days of the  execution  of this  Agreement,  Seller
shall  provide  Buyer with copies of the most recent survey of the Real Property
in  Seller's  possession,  if any.  Promptly  following  the  execution  of this
Agreement,  Buyer shall obtain, at Seller's sole cost and expense,  a commitment
for an ALTA Owner's Policy of Title Insurance (the "Title Commitment"). Promptly
following the execution of this Agreement,  Buyer shall obtain,  at Buyer's sole
cost and expense, an ALTA as-built survey of the Real Property (the "Survey").

      If (i) any  matter  disclosed  on the  Survey  or (ii)  matters  listed as
exceptions in the Title Commitment are not each satisfactory to Buyer, it shall,
on or before the  expiration  of the  Inspection  Period,  provide  Seller  with
written  notice of such  objections  (the  "Objection  Notice") and if Seller is
unable or unwilling to cure such objections  within five (5) days after the date
the Objection  Notice is received (the "Title  Response  Period"),  Buyer's sole
remedy shall be to terminate  this  Agreement by giving written notice to Seller
on or before the  expiration of the Title Response  Period,  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  except Seller shall be obligated to cure, obtain title coverage over
or bond over all objections constituting mortgages, other voluntary encumbrances
securing the repayment of money or other monetary liens, on or before the Escrow
Closing Date,  provided,  however,  that nothing herein shall obligate Seller to
cure,  obtain  title  coverage  over or bond over  monetary  liens  (other  than
mortgages or  voluntary  encumbrances  securing  the  repayment of money) in any
amount in excess of  $10,000.  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.

            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 on the Title  Commitment and Survey 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.

            At the Close of Escrow, the Seller shall assign without recourse the
Leases,  Contracts  which are not to be terminated  and  warranties,  if any, to
Buyer and Buyer shall assume Seller's obligations  thereunder from and after the
date of Close of Escrow and Seller  shall  convey the  Personal  Property to the
Buyer by quitclaim bill of sale.

            Representations and Warranties

                  The Seller hereby  represents  and warrants to the Buyer as of

Seller enforceable against it in accordance with its terms.

      (c) All  information  pertaining  to the  Property  prepared by Seller and
delivered to Buyer is true and correct in all material respects.

      (d)  Seller is not a foreign  person  and is a "United  States  Person" as
defined in Section 7701(a)(30) of the Internal Revenue code of 1986, as amended.

creditors,   receiverships,   conservatorships   or  voluntary  or   involuntary

Seller or to Seller's actual knowledge,  pending or threatened against Seller or
the Property.

      Each  representation  and  warranty  contained  in this  Section  6.4.1 is
subject to being updated by Seller in writing on or before the expiration of the
Inspection Period or the Title Response Period if such period extends beyond the
Inspection Period and the update concerns title or survey matters,  and shall be
deemed to have been amended as provided in this Agreement and by the information
contained in Seller deliveries of Due Diligence materials under Sections 5.1 and
5.2 and such other information  delivered to Buyer in writing under the terms of
the  Agreement or  otherwise  obtained by Buyer prior to the  expiration  of the
Inspection  Period or the Title Response  Period,  if such period extends beyond
the expiration of the Inspection  Period and the  information  concerns title or
survey matters.  Each of the representations and warranties contained in Section
6.4.1 is hereby qualified to Seller's actual  knowledge  without further inquiry
except as provided  below.  For purposes of Section  6.4.1  actual  knowledge of
Seller  shall  mean the  actual  awareness  of Rock  D'Errico  (who has been the
officer  of  the  general  partner  of  Seller  with  primary  asset  management
responsibility  for the Property).  Such individual  shall have no obligation to
make any further inquiry of any persons, but such actual knowledge obtained from
any other  source  shall be deemed to be actual  knowledge  for purposes of this
Section 6.4.1.

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

      (a) The Buyer is a  corporation  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) 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.

      (c) The financial statements provided pursuant to Section 5.4 are true and
complete in all material respects.

              The  representations and warranties of Seller contained in Section
6.4.1 shall survive Close of Escrow until the earlier of (i) the  dissolution of
the Seller during the normal course of business, or (ii) six (6) months.

            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.

            On the Escrow Closing Date,  Seller shall assign without warranty to
Buyer any rights Seller has against prior Property  owners,  adjoining  property
owners,   governmental  agencies,  and  any  and  all  third  parties  regarding
environmental  conditions  at, or related to, the  Property  ("Seller  Claims").
Neither  Buyer nor any  assignee  of Buyer may  assign  Seller  Claims to future
owners of the Property or any other third party without Seller's consent,  which
consent  shall be granted if the  indemnity  under this  Section will retain the
same net worth or greater upon the assignment.

      Buyer shall indemnify, release and hold harmless the Seller, its officers,
directors,  partners,  employees and agents from and against any and all claims,
demands  (including  without  limitation any clean-up order,  monitoring  order,
testing  order,  remediation  order or other orders of any kind,  including  the
Order), actions,  administrative  proceedings,  costs, liabilities,  judgements,
damages,  fines,  encumbrances,  liens,  penalties,  liabilities and expenses of
whatever  kind in  nature  incurred  at any time  which  arise  out or relate to
environmental  contamination  on the Property.  Buyer hereby releases the Seller
from any claims which arise out of or relate to  environmental  contamination on
the Property.  Buyer hereby  expressly  waives the benefits and  protections  of
Section 1542 of the Civil Code of the State of California as to unknown  claims.
Buyer's  breach  of such  the  obligations  under  this  Section  will be  fully
actionable  by Seller at law or in equity.  The  obligations  under this Section
shall survive the Close of Escrow.

                                    ARTICLE 6
                                 CLOSE OF ESCROW

"Escrow  Closing  Date"),  unless  such  day is not a day on  which  the  County

            On or before  the Escrow  Closing  Date the Buyer  shall  deliver or

                                    ARTICLE 7
                            CASUALTY AND CONDEMNATION

            If the Improvements  are materially  damaged or destroyed by fire or
any other  casualty  such that the cost of repair  exceeds  $250,000 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 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) 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).

            If any 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 8
                              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.  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  Scott  Mathisen  and  Doug  Yoder  of  CB  Commercial
("Seller's  Agent"),  and no  finder's  fee is payable in  connection  with this
transaction.  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. All commissions,  if any, to the brokers named herein shall be paid
by the Seller but shall be payable only if the transactions  contemplated herein
are consummated.

                                    ARTICLE 9
                        DEFAULT, TERMINATION AND REMEDIES

            In the event that 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.

            NOTWITHSTANDING   ANYTHING  TO  THE   CONTRARY   CONTAINED  IN  THIS
AGREEMENT,  IF  BUYER  HAS  NOT  TERMINATED  THIS  AGREEMENT  ON OR  BEFORE  THE
EXPIRATION OF THE  INSPECTION  PERIOD OR THE  EXPIRATION  OF THE TITLE  RESPONSE
PERIOD,  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 5.7 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.

SELLER'S INITIALS /S/ RMD     BUYER'S INITIALS __________________

                  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

shall extend to and be obligatory  upon the permitted  successors and assigns of
the respective parties to this Agreement.

            Except  as  otherwise   specifically  provided  herein,  any  notice
required or permitted to be delivered  under this Agreement  shall be in writing

party to Escrow  Holder shall be  simultaneously  given to the other party.  Any
notice given by a party to the other party  relating to its  entitlement  to the
Escrowed Amount shall be simultaneously given to the Escrow Holder.

held to  include  the  plural  and  vice  versa,  unless  the  context  requires
otherwise.

            The captions used in connection  with the Articles of this Agreement
are for convenience  only and shall not be deemed to extend,  limit or otherwise
define or construe the meaning of the language of this Agreement.

            Nothing in this Agreement, express or implied, is intended to confer
upon any person,  other than the parties hereto and their respective  successors
and assigns, any rights or remedies under or by reason of this Agreement.

            This Agreement may be amended only by a written instrument  executed
by the Seller and the Buyer (or Buyer's assignee or transferee).

            This Agreement  embodies the entire agreement between the Seller and
the Buyer with respect to the transaction  contemplated  in this Agreement,  and
there  have  been  and  are  no   covenants,   representations,   warranties  or
restrictions  between  the Seller and the Buyer with regard  thereto  other than
those set forth or provided  for in this  Agreement.  Any prior  agreements  are
hereby terminated and superseded by this Agreement.

            This Agreement  shall be construed  under and in accordance with the
laws of the State of California.

            This Agreement may be executed in two (2) or more counterparts, each
of which shall be an original but such  counterparts  together shall  constitute
one and the same instrument  notwithstanding  that both the Buyer and Seller are
not signatory to the same counterpart.

            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.
This  Agreement  shall  terminate  upon any such request from Buyer  pursuant to
Sections 4.5, 5.3 and 6.1 and Article 8 above.

            In the event of any  disagreement  between the  parties,  the Escrow
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  gross  negligence  or
willful  misconduct,  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.

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

            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.  This Section is not intended to limit recovery for
breach of Section 6.6.

            In order that Seller may liquidate after the Close of Escrow without
having to maintain reserves as a result of any continuing  obligations hereunder
and notwithstanding any provision in this Agreement to the contrary,  except for
the  obligations  under  Section  6.6 which  survive  the Close of  Escrow,  all
obligations  of the  Seller  under this  Agreement  which  survive  the Close of
Escrow, including,  without limitation, tax adjustments pursuant to Section 3.4,
utility adjustments  pursuant to Section 3.6, rent and lease expense adjustments
pursuant to Section 3.7.3,  Seller's  representations and warranties pursuant to
Section 6.4.1 and Section 5.3,  Seller's  obligation to assign  Seller's  Claims
pursuant   Section   6.6  and   Seller's   representation   and   warranty   and
indemnification  pursuant to Article 9 shall only  survive  until the earlier of
(i) the dissolution of the Seller during the normal course of business,  or (ii)
six (6) months.

                                   ARTICLE 12
                           IRS FORM 1099-S DESIGNATION

            In  order to  comply  with  information  reporting  requirements  of
Section  6045(e) of the  Internal  Revenue  Code of 1986,  as  amended,  and the
Treasury  Regulations  thereunder,  the parties agree (1) to execute an IRS Form
1099-S  Designation  Agreement in the form  attached  hereto as Schedule F at or
prior to the Close of Escrow to designate the Escrow Holder (the  "Designee") as
the party who shall be responsible  for reporting the  contemplated  sale of the
Property to the Internal Revenue Service (the "IRS") on IRS Form 1099-S;  (2) to
provide the Designee with the information necessary to complete Form 1099-S; (3)
that  the  Designee  shall  not be  liable  for the  actions  taken  under  this
Agreement,  or for the consequences of those actions,  except as they may be the
result of gross  negligence  or willful  misconduct on the part of the Designee;
and (4) that the Designee  shall be  indemnified by the parties for any costs or
expenses incurred as a result of the actions taken hereunder, except as they may
be the  result of gross  negligence  or  willful  misconduct  on the part of the
Designee. The Designee shall provide all parties to this transaction with copies
of the IRS Forms 1099-S filed with the IRS and with any other  documents used to
complete IRS Form 1099-S.

      IN WITNESS  WHEREOF,  the parties have executed this  instrument as of the
day and year first set forth above.

THIS  FIRST  AMENDMENT  TO  JOINT  ESCROW  INSTRUCTIONS  AND  PURCHASE  AND SALE
AGREEMENT  ("First  Amendment")  is made and  entered  into as of the 9th day of

A.    Seller and Buyer entered into that certain Joint Escrow  Instructions  and

                                    COVENANTS

      Seller and Buyer agree as follows:

      1.  Inspection  Period.  With  references  to Section 5.3 of the  Purchase
      Agreement,  and  notwithstanding  the  provisions  of such  Section to the
      contrary, the Inspection Period shall be extended through April 15, 1998.

      2.  Counterparts.  This First  Amendment may be executed in  counterparts,
      each of which will constitute an original. This First Amendment shall only
      be effective if a counterpart is signed by both Seller and Buyer.

      3. Facsimile Signatures Seller and Buyer each (a) has agreed to permit the

              THIRD AMENDMENT TO JOINT ESCROW INSTRUCTIONS
                         AND PURCHASE AND SALE AGREEMENT

      This Third  Amendment to Joint Escrow  Instructions  and Purchase and Sale
Agreement  is made  and  entered  into as of the  5th day of May,  1998,  by and
between  PaineWebber  Qualified  Plan  Property  Fund  Four,  L.P.,  a  Delaware

("Buyer") and Buyer's nominee,  Limar Realty Corp #27, ("Buyer's  Nominee") (the
"Third Amendment").

                                    RECITALS

      Whereas,   Buyer  and  Seller  entered  into  that  certain  Joint  Escrow

dated  April 15,  1998 and a  certain  Letter  Agreement  dated  April 16,  1998

                                    COVENANTS

      Now therefore, for good and valuable consideration,  the receipt and legal
sufficiency  of which are hereby  acknowledged,  the Buyer,  Seller and  Buyer's
Nominee agree as follows:

      1. With  reference  to Section 7.1 of the Joint  Escrow  Instructions  and
Purchase  and Sale  Agreement  dated as of March 11, 1998,  the "Escrow  Closing

      2.  Simultaneously  with the  execution of this Third  Amendment,  Buyer's

the Escrowed  Amount shall only be refundable  pursuant to Article 8 and Section
10.1 of the Joint Escrow  Instructions  and Purchase and Sale Agreement dated as

      5. Buyer and Buyer's Nominee waive all objections to the Amendment of Site
Cleanup  Requirements  (Order  No.  95-210)  prepared  by George  Lincoln of the
Regional Water Quality Control Board, except insofar as the objections relate to
the identity of the property  owner being Limar Realty Corp #27 instead of Limar
Realty Corp #36.

      6. This Third  Amendment  may be executed in  counterparts,  each of which
will  constitute an original.  This Third Amendment shall only be effective if a
counterpart  is signed by Seller,  Buyer and Buyer's  Nominee and  delivered  to
Seller by 10:00 am Pacific time May 6, 1998.

      7.  Seller,  Buyer and Buyer's  Nominee  each (a) has agreed to permit the

any  defenses  to the  enforcement  of this Third  Amendment  and the  documents
affecting the transaction contemplated by this Third Amendment based on the fact
that a signature was sent by telecopy only.

      8. Any  inconsistency  between the provisions of this Third  Amendment and
the  Purchase  Agreement  shall be  governed  by the  provisions  of this  Third
Amendment. Except as otherwise specifically defined in this Third Amendment, all
capitalized terms as used in this Third Amendment shall have the same meaning as
ascribed  to such  terms  in the  Purchase  Agreement.  Except  as  specifically
modified by the provisions of this Third Amendment, the Purchase Agreement shall
remain in full force and effect and is hereby  ratified  by the  parties to this
Third Amendment.

herein shall have the meanings ascribed to them in the Agreement.

      B.  Assignor may have certain  rights and claims  against  prior  Property

such other information reasonably acceptable to Assignor.

      3. Assignee shall indemnify,  release and hold harmless the Assignor,  its

      THIS   ASSIGNMENT  OF  TENANT  LEASES  AND   ASSUMPTION   AGREEMENT   (the
"Assignment")  is executed and  delivered on this 29th day of May,  1998, by and
between PaineWebber  Qualified Plan Property Fund Four, L.P., a Delaware limited
partnership  ("Assignor")  and Limar Realty Corp #27, a  California  corporation
("Assignee").

                                   WITNESSETH:

      Assignor has  heretofore  entered into certain  tenant leases with tenants
covering space in the buildings located on those certain tracts of land situated
in 680 West  Maude  Avenue,  Sunnyvale,  California  (the  "Property"),  as more
particularly described on Exhibit "A" attached hereto and made a part hereof.

      Pursuant to that certain Joint Escrow  Instructions  and Purchase and Sale
Agreement  dated as of March 11, 1998,  between  Assignor,  Assignee and Chicago
Title Company,  as amended by the First  Amendment to Joint Escrow  Instructions
and Purchase and Sale  Agreement  dated April 9, 1998,  the Second  Amendment to
Joint Escrow  Instructions  to Purchase and Sale Agreement  dated April 15, 1998
and a certain Letter  Agreement  dated April 16, 1998  (collectively,  "Purchase
Agreement")  Assignee desires to acquire from Assignor,  and Assignor desires to
sell and assign to Assignee, the Lessor's interest in all leases of the Property
without recourse.

      NOW,  THEREFORE,  for  and  in  consideration  of  the  premises  and  the
agreements and covenants herein set forth,  together with the sum of Ten Dollars
($10.00) and other good and valuable  consideration  this day paid and delivered
by Assignee to Assignor,  the receipt and  sufficiency  of which by Assignor are
hereby confessed and acknowledged,  Assignor does hereby ASSIGN,  TRANSFER,  SET
OVER, and DELIVER unto Assignee,  without recourse,  all of the leases listed on
Exhibit B attached hereto (the "Leases"),  and all of the rights,  benefits, and
privileges of the lessor thereunder (all such properties, rights, and interests,
subject as  aforesaid,  being  hereinafter  collectively  called  the  "Assigned
Leases"),  including  the  security  deposits  under the  Leases as set forth in
Schedule 1 attached hereto.

      Such  assignment of the Assigned Leases by Assignor to Assignee is made on
the following terms and conditions:

A. By its  acceptance  of the Assigned  Leases,  Assignee  assumes and agrees to
perform all of the terms,  covenants,  and conditions of the Assigned  Leases on
the part of the lessor therein  required to be performed from and after the date
hereof,  including,  but not limited to, the  obligation  to repay in accordance
with the terms of the Assigned Leases to the lessees thereunder any security and
prepaid rental deposits to the extent paid or credited to Assignee and agrees to
indemnify, defend, save, and hold harmless Assignor from and against any and all
loss,  expense,  liability,  claims,  or  causes  of  action  including  without
limitation  reasonable  attorney's fees and court costs, existing in favor of or
asserted by the lessees under the Assigned  Leases arising out of or relating to
Assignee's failure to perform any of the assumed obligations of the lessor under
the Assigned Leases after the date hereof.

A. Assignor  covenants and agrees to indemnify,  defend,  save and hold harmless
Assignee from and against any and all loss, expense, liability, claims or causes
of action  including  without  limitation  reasonable  attorney's fees and court
costs, existing in favor of or asserted by the lessees under the Assigned Leases
arising  out  of or  relating  to  Assignor's  failure  to  perform  any  of the
obligations  of the lessor under the  Assigned  Leases prior to the date hereof.
The foregoing sentence shall be without recourse to the Assignor as provided for
in the Purchase Agreement.

A. The Assignee hereby  acknowledges the receipt of all security  deposits under
the Leases as set forth in Schedule 1 attached hereto.

A. This  Assignment  shall be governed by the law of the State of California and
all of the  covenants,  terms,  and conditions set forth herein shall be binding
upon and shall inure to the benefit of the parties  hereto and their  respective
successors  and  assigns.  The  obligations  pursuant to this  Assignment  shall
survive the delivery of the Grant Deed for the Property by Assignor to Assignee.

A. This  Assignment  may be  executed in two (2) or more  counterparts,  each of
which shall be an original but such  counterparts  together shall constitute one
and the same instrument  notwithstanding that both the Assignor and Assignee are
not signatory to the same counterpart.
