                           PROXY STATEMENT/PROSPECTUS

   
                             MISSION WEST PROPERTIES
                          MISSION WEST PROPERTIES, INC.


                       102,197,299 Shares of Common Stock
    

     This proxy  statement/prospectus (the "Proxy  Statement/Prospectus") is the
proxy  statement  of Mission West  Properties,  a  California  corporation  (the
"Company").  This proxy statement is being furnished to holders of common stock,
no par value  (the  "Common  Stock"),  of the  Company  in  connection  with the
solicitation  of proxies by the board of  directors  of the Company for use at a
special meeting of shareholders to be held at ____ a.m., on _____________, 1998,
at _______________,  ________________,  _________________, California, including
any adjournments ("Special Meeting").

     In December 1996,  shareholders  approved the sale of substantially  all of
the  Company's  assets and the  distribution  of the net  proceeds on a pro rata
basis. Subsequent to the sale of the assets, a group of investors led by Carl E.
Berg  approached  the Company with a proposal to  recapitalize  the Company and,
rather than dissolve the Company, continue the business of the Company under the
control of Mr. Berg with a portfolio of new investment properties. Following the
initial investment in the Company by the Berg-led investment group and the final
distribution  of the proceeds of the asset sales to  shareholders,  the American
Stock Exchange ("AMEX") halted trading of the Company's Common Stock.

     Thereafter,   Mr.  Berg  proposed  that  the  Company   undertake   several
transactions intended to provide the Company with additional capital and control
of substantial real estate holdings of Mr. Berg, members of his immediate family
and certain  entities which they control (the "Berg  Group").  In July 1998, the
Company  acquired  the sole  general  partner  interest in each of four  limited
partnerships  holding  properties  previously  controlled  by the Berg Group and
certain other  persons.  The board of directors  believes that the proposals and
related  transactions are in the best interests of the Company, and has approved
the transactions  described below. At the Special Meeting,  shareholders will be
asked to consider and vote on the following proposals:

     1. Pursuant to rules of the AMEX, the  shareholders  of the Company will be
asked to  approve  the sale and  issuance  by the  Company at $4.50 per share of
6,495,058  shares of Common Stock to  accredited  investors  pursuant to binding
subscription  agreements,  which are subject to such  shareholder  approval (the
"Private Placement").

   
     2. The Company will apply the proceeds from the Private Placement, existing
cash and other  working  capital  sources to fund the  payment of $33.9  million
under 7.25% interest demand notes ("Demand Notes") issued by the Company for the
acquisition of the sole general  partner  interests  representing  approximately
12.11% of the  total  partnership  interests  in each of four  existing  limited
partnerships  (collectively the "Operating  Partnerships")  owning approximately
4.34 million  square feet of leased  buildings  used for  offices,  research and
development, light manufacturing,  and assembly ("R&D Property") under the terms
of an agreement among the Company, the Berg Group and certain other persons (the
"Acquisition  Agreement").  The  Acquisition  Agreement  also  provides  for the
Company to  acquire,  through the  Operating  Partnerships,  approximately  1.02
million  rentable square feet of R&D Property to be constructed and leased prior
to  acquisition  by  the  Operating   Partnerships  (the  "Pending   Development
Projects")  from  certain  members of the Berg  Group,  and an option to acquire
future  building  developments  on land currently held by certain members of the
Berg Group. Collectively,  these transactions (the "Berg Acquisition") allow the
Company to acquire control of approximately  5.4 million rentable square feet of
R&D Property previously controlled  principally by the Berg Group. To enable the
Company to begin reporting  financial data for the Operating  Partnerships  with
the Company's consolidated financial statements as of July 1, 1998, the Company,
the Berg Group and the other parties to the  Acquisition  Agreement  executed an
amendment  providing  for  the  Company's  acquisition  of its  general  partner
interest in each of the Operating Partnerships,  and the contribution of certain
properties to one of the Operating Partnerships,  effective as of that date (the
"Partnership  Closing"). At the Special Meeting, the Company's shareholders will
be asked to ratify the Partnership Closing and to approve the other transactions
comprising the Berg Acquisition and related matters.

     3. Pursuant to AMEX rules, the Company also seeks  shareholder  approval of
the  issuance  of up to  93,398,705  shares  of  Common  Stock  upon the  future
redemption or exchange of 100,825,478 units of limited  partnership  interest in
the Operating  Partnerships  ("L.P.  Units"),  including  33,919,072  L.P. Units
issuable upon the Operating Partnerships' acquisition of the Pending Development
Projects  from  members of the Berg Group  pursuant  to the terms of an Exchange
Rights Agreement among the company,  the Operating  Partnerships and the Limited
Partners (the "Exchange  Rights  Agreement").

     4.  Shareholders are asked also to approve a proposal to reincorporate  the
Company  under  the  laws  of the  State  of  Maryland  through  a  merger  (the
"Reincorporation  Merger")  with and  into  Mission  West  Properties,  Inc.,  a
Maryland  corporation  ("Mission  West-Maryland"),  a newly formed  wholly owned
subsidiary  of  the  Company.   Mission  West-Maryland  will  be  the  surviving
corporation  with articles of  incorporation  (the  "Charter")  and bylaws which
differ  materially from those of the Company.  Mission  West-Maryland was formed
for the  purpose of  redomiciling  the  Company as a  Maryland  corporation  and
acquiring,  recapitalizing  and  continuing  the business and  operations of the
Company.  In the  Reincorporation  Merger,  shares of the Company's Common Stock
outstanding at the effective time of the merger will be converted into shares of
common stock,  $0.001 par value per share of Mission  West-Maryland ("New Common
Stock") on a one-for-one basis (the "Exchange Ratio").  Unexercised employee and
consultant  stock  options to purchase  605,000  shares of Common  Stock will be
exchanged  for new stock  options to  purchase  the same number of shares of New
Common  Stock at the  Exchange  Ratio.  Following  the  Reincorporation  Merger,
Mission  West-Maryland  expects  to qualify as a Real  Estate  Investment  Trust
("REIT")  for  federal  income  tax  purposes  and  conduct  its  business  on a
self-administered,  self-managed,  and fully integrated basis going forward. The
Charter  and bylaws  will  include  provisions  related to the  preservation  of
Mission   West-Maryland's   status   as  a  REIT.   As   used   in  this   Proxy
Statement/Prospectus  the term  "Company"  may  refer to both  the  Company  and
Mission West-Maryland unless the discussion concerns the Reincorporation Merger,
the Charter, or the Mission West-Maryland bylaws.

     If the shareholders  approve the Private Placement,  the acquisition of the
Pending  Development  Projects and other future Berg Developments,  the Exchange
Rights Agreement, and authorize all shares of Common Stock to be issued pursuant
to any of these  transactions,  an  additional  closing  will  occur on the last
business day of the month in which the Special  Meeting is held  (referred to in
this  Proxy  Statement/Prospectus  as "the  final  closing  date  for  the  Berg
Acquisition").

     This Proxy  Statement/Prospectus  is also the  prospectus  of the Company's
successor,  Mission  West-Maryland,  to be delivered to the  shareholders of the
Company in  connection  with the  Reincorporation  Merger and the exchange  with
existing  equity holders of (i) 1,698,536  shares of Common Stock for New Common
Stock,  (ii) the exchange of  outstanding  employee  stock options issued by the
Company for identical employee stock options of Mission West-Maryland, and (iii)
the  reservation of 93,398,705  shares of New Common Stock for issuance upon any
future exchange of L.P. Units as a result of the  Reincorporation  Merger.  This
Proxy  Statement/Prospectus  is also the prospectus of Mission West-Maryland for
the  reoffer  and resale of up to  6,495,058  shares of New  Common  Stock to be
delivered  in  exchange  for  shares of Common  Stock  acquired  in the  Private
Placement by the purchasers of such shares.

     The  Company  has  filed a  Registration  Statement  on Form  S-4  with the
Securities  and Exchange  Commission  pursuant to the Securities Act of 1933, as
amended  with  respect   securities  to  be  issued  in   connection   with  the
Reincorporation Merger.

    

     The  Common  Stock is traded  on the AMEX and the  Pacific  Exchange,  Inc.
("PCX") under the symbol "MSW." On ______ __, 199_, the last reported sale price
of the  Common  Stock on the  AMEX was  $_____________.  See  "INFORMATION  WITH
RESPECT TO THE  COMPANY--Price  Range of the Shares and  Distribution  History."
Based on that price and assuming  approval of all proposals and the consummation
of the contemplated transactions,  the total market value of the Company and the
Operating Partnerships would be approximately $__________.


      SEE "RISK FACTORS" BEGINNING ON PAGE 9 FOR A DISCUSSION OF MATERIAL
          RISKS THAT SHOULD BE CONSIDERED IN EVALUATING THE PROPOSALS.

   THESE SHARES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
     EXCHANGE COMMISSION NOR HAS THE COMMISSION PASSED UPON THE ACCURACY
          OR ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION TO THE
                      CONTRARY IS A CRIMINAL OFFENSE

               The date of this Prospectus is _____________, 1998

              SUMMARY OF THE UPREIT TRANSACTIONS AND PURPOSE OF THE
                                 SPECIAL MEETING

THE FOLLOWING BRIEFLY SUMMARIZES THE PROPOSALS TO BE VOTED UPON.

BACKGROUND

     Shareholders  previously  approved  the  sale of  substantially  all of the
assets of the Company and the  distribution of the net proceeds of sale on a pro
rata basis. Subsequent to the distribution,  Carl E. Berg approached the Company
with a proposal to  recapitalize  the  Company,  and,  rather than  dissolve the
Company,  continue  the  business of the  Company  under the control of the Berg
Group with a  portfolio  of new  investment  properties.  After the  purchase of
shares representing a controlling  interest in the Company by certain members of
the Berg Group and other accredited  investors and the final distribution to all
previous  shareholders in October 1997, the AMEX halted trading of the Company's
Common  Stock   because  the  Company  no  longer  met  AMEX   minimum   listing
requirements.

PARTIES TO AND TERMS OF THE BERG ACQUISITION

   
     In May 1998, the Company,  the Berg Group and certain other persons entered
into an agreement (the "Acquisition  Agreement") providing,  among other things,
for the Company's  acquisition  of interests as the sole general  partner in the
four existing limited  partnerships  (referred to collectively as the "Operating
Partnerships"),  which hold  approximately  4.34 million rentable square feet of
office/research and development/manufacturing  space ("R&D Property") located in
the portion of the San Francisco Bay Area known as "Silicon  Valley," as well as
rights to acquire  additional  R&D  Properties,  and  related  transactions,  as
described  below.  In July 1998, the Company and all parties to the  Acquisition
Agreement  signed an Amendment to Acquisition  Agreement under which they agreed
to consummate the Company's  acquisition of the general partner interests in the
Operating  Partnerships (the "Partnership  Closing") effective for financial and
income  accounting  and  reporting  purposes  as of July 1, 1998 to  enable  the
Company to include  results of operations,  assets and other  financial data for
the Operating  Partnerships with the Company's consolidated financial statements
for the second half of 1998.  The Company  effected the  Partnership  Closing by
issuing to the Operating  Partnerships separate Demand Notes bearing interest at
7.25% per annum equal to the purchase  price of the  Company's  general  partner
interest  in each such  partnership.  Each  Demand Note is payable no later than
July 1,  2000.  The  total  principal  amount  of the  Demand  Notes  issued  in
connection  with the  Partnership  Closing  was $35.2  million,  of which  $33.9
million is presently outstanding.

     As a consequence of the Partnership  Closing,  the Company now controls the
Operating  Partnerships,  which are  governed by the  Delaware  Revised  Uniform
Limited Partnership Act ("DRULPA").  The individual  Operating  Partnerships are
named Mission West Properties,  L.P.  ("MWP"),  Mission West Properties,  L.P. I
("MWP  I"),  Mission  West  Properties,  L.P.  II ("MWP  II") and  Mission  West
Properties,  L.P. III ("MWP III").  MWP was organized  under the DRULPA in 1995;
MWP I and MWP II were general  partnerships  formed more than 15 years ago which
converted to limited partnerships under the DRULPA in December 1997; and MWP III
was  formed in 1983 as a  California  limited  partnership  and  converted  to a
Delaware limited partnership under the DRULPA at the Partnership Closing. No new
entity has been created in  connection  with the  Partnership  Closing,  and the
Company  does not  intend to create a new entity to  conclude  any aspect of the
Berg   Acquisition.   All  limited   partnership   interests  in  the  Operating
Partnerships  were  converted  into  59,479,633  units  of  limited  partnership
interest  ("L.P.  Units") in connection  with the  Partnership  Closing.  In the
aggregate those L.P. Units represent  ownership of  approximately  87.89% of the
Operating Partnerships.  Under the Acquisition Agreement,  all L.P. Units in the
Operating  Partnerships  may be  exchanged  for  shares of  Common  Stock of the
Company  pursuant to the terms of an Exchange  Rights  Agreement  (the "Exchange
Rights Agreement"), which is subject to approval by the Company's shareholders.

     Prior to the Partnership Closing,  MWP, MWP I and MWP II were controlled by
Carl E. Berg and his brother Clyde J. Berg, who have been engaged in developing,
owning, operating, acquiring and selling Silicon Valley R&D Properties under the
name  "Berg & Berg  Developers"  ("Berg & Berg")  for  nearly 30 years.  Another
Silicon Valley developer, John T. Kontrabecki ("Kontrabecki") controlled MWP III
as its sole general partner prior to the Partnership Closing, and Carl and Clyde
Berg owned 50% of that partnership as limited partners. Prior to the Partnership
Closing,  certain members of the Berg Group held R&D Properties  outside of MWP,
MWP I and MWP  II,  and Mr.  Kontrabecki  was a  general  partner  in two  other
partnerships  (in which  members  of the Berg  Group  held  substantial  limited
partner  interests).  To  consolidate  title to those R&D Properties in a single
entity,  the parties agreed pursuant to the Acquisition  Agreement to contribute
their  respective  R&D Properties to MWP in exchange for L.P.  Units.  Under the
Amendment to Acquisition  Agreement,  all the proposed transfers to MWP occurred
at the Partnership Closing,  except for the conveyance of certain R&D Properties
representing  approximately  0.144  million  rentable  square feet (the "Fremont
Properties"),   which  was  consummated  on  September  17,  1998.  All  of  the
individuals  and entities  transferring  R&D Properties to MWP pursuant to their
obligations under the Acquisition  Agreement are accredited investors within the
meaning of the federal  securities  laws,  and all such  entities are  privately
owned.

     Of the total R&D Property rentable square footage owned and operated by the
Operating   Partnerships   following   the   Partnership   Closing,   properties
representing  approximately  3.78  million  rentable  square  feet were owned or
controlled by members of the Berg Group and constitute the historical properties
managed by Berg & Berg (the "Berg Properties"). Other R&D Properties, consisting
of approximately 0.56 million rentable square feet, (the "Acquired  Properties")
represent the Fremont  Properties,  and certain R&D Properties (the "Kontrabecki
Properties")   held  by  the  three  limited   partnerships   (the  "Kontrabecki
Partnerships") previously controlled by John Kontrabecki.

     Under the terms of the Acquisition  Agreement,  the Operating  Partnerships
and the Company also agreed,  subject to shareholder  approval,  to enter into a
Pending  Projects  Acquisition  Agreement  (the  "Pending  Projects  Acquisition
Agreement"),  which permits the  acquisition  by the Operating  Partnerships  of
approximately  one million  additional  rentable square feet upon the completion
and leasing of a number of the  Pending  Development  Projects  owned by certain
members  of  the  Berg  Group  and  under  current  development  by  Berg & Berg
Enterprises,  Inc. ("BBE").  The owners of the Pending Development  Projects may
obtain cash, or at their option,  L.P.  Units. A total of 33,919,072  L.P. Units
may be issued in  exchange  for the  Pending  Development  Projects.  Subject to
shareholder approval of the Pending Projects Acquisition Agreement,  those units
may be exchanged for 33,919,072  shares of Common Stock pursuant to the Exchange
Rights  Agreement.  On August 6,  1998,  Berg & Berg and  Microsoft  Corporation
("Microsoft")  signed a lease with respect to an approximate 515,000 square foot
property  to  be  constructed  by  Microsoft  on  L'Avenida  in  Mountain  View,
California,  one of the  sites  comprising  the  Pending  Development  Projects.
Microsoft  controls the construction of this facility,  which is scheduled to be
completed in phases between March and May 1999. The Company will acquire the R&D
Properties to be built on the L'Avenida site when and if  construction  has been
completed and the buildings have been fully leased.  Upon any acquisition by the
Company of the Pending Development  Projects,  their owners may elect to receive
cash or L.P. Units from the Operating  Partnerships.  The Acquisition  Agreement
also gives the Company an option to acquire, through the Operating Partnerships,
any future R&D Property  developments on approximately  162 net acres of Silicon
Valley  land  owned  by  certain  members  of the Berg  Group  (the  "Berg  Land
Holdings")  under the  terms of the Berg Land  Holdings  Option  Agreement  (the
"Option  Agreement").  The owners of the Berg Land Holdings may elect to receive
cash or L.P. Units.  The Company will not acquire any properties  directly.  The
Company will enter into the Pending  Projections  Acquisition  Agreement and the
Option Agreement only following shareholder approval at the Special Meeting. See
"Background of the UPREIT transactions," and "THE ACQUISITION AGREEMENT."
    


PRIVATE PLACEMENT

     The Company also has entered into  binding  agreements,  subject to certain
conditions,  to sell  6,495,058  shares  of  Common  Stock at $4.50 per share to
accredited  investors in the Private Placement,  following  shareholder approval
required  by the AMEX.  Of the total  number of shares to be sold in the Private

purchasers  of such shares have agreed to pay a placement fee of $0.05 per share
to Ingalls & Snyder, for which the company has no liability.

CAPITALIZATION

   
     Taking into  account the shares  issued in the Private  Placement  and L.P.
Units to be outstanding  immediately  after the closing of the Berg Acquisition,
the total number of L.P.  Units and shares of Common  Stock  entitled to receive
distributions  of  cash  flow  from  the  Operating  Partnerships  directly,  or
indirectly through dividends paid by the Company, (collectively the "Outstanding
Shares") will be  67,673,227.  See  "BACKGROUND  OF THE UPREIT  TRANSACTIONS  --
Summary of the Transactions" and "-- Pro Forma Capitalization."
    

REINCORPORATION MERGER

     Pursuant to a merger agreement ("Merger Agreement") between the Company and
its wholly owned subsidiary, Mission West-Maryland,  the Company will merge into
Mission West-Maryland following shareholder approval and the consummation of the
Berg  Acquisition  and the  Private  Placement.  Following  these  transactions,
Mission  West-Maryland  intends  to elect to  become a REIT.  In  approving  the
Reincorporation  Merger,  the shareholders also will approve the Charter and the
bylaws of Mission West-Maryland. See "THE REINCORPORATION MERGER."

STRUCTURE OF THE UPREIT TRANSACTIONS

   
The Limited Partners' ownership of interest prior to the UPREIT Transactions and
their respective L.P. Unit allocations are as follows:

REASONS FOR THE BERG ACQUISITION

     The board of directors of the Company  believes  that the Berg  Acquisition
and the Private  Placement  will  provide the Company with  substantial  working
capital,  a  strong  real  property  portfolio  and  an  effective  real  estate
operation.  The board of  directors  further  believes  that these  transactions
provide an  opportunity  for the Company to  significantly  enhance  shareholder
value.  See  "BACKGROUND  OF  THE  UPREIT  TRANSACTIONS--Reasons  for  the  Berg
Acquisition and Private Placement."

DESCRIPTION OF THE PROPERTIES

   
     All of the Berg Properties are located in Silicon Valley.  All together the
Operating  Partnerships will own 69 R&D Properties located on 61 separate sites.
As of September 30, 1998, the Berg Properties  were 100% occupied,  with a total
of 73 tenants principally engaged in the technology  business,  and the Acquired
Properties  were 100% occupied by a total of 10 tenants.  On September 23, 1998,
the  Company  obtained  $130  million of new  secured  debt  financing  from The
Prudential Insurance Company of America  ("Prudential") (the "Prudential Secured
Loan")  at a rate  of  6.56%  per  annum,  which  is  secured  by 18  Properties
consisting of 24 buildings and six of the Acquired  Properties.  The proceeds of
the Prudential Secured Loan were used to repay existing debt secured by the Berg
Properties  and the  Acquired  Properties,  incurred  prior  to the  Partnership
Closing,  including debt incurred to fund substantially all of a distribution of
approximately  $138.7 million to members of the Berg Group.  Effective September
30, 1998, the Company and Operating  Partnerships assumed a $100 million line of
credit with Wells Fargo Bank N.A. (the "Wells Fargo Line")  provided to the Berg
Group members and secured by certain of the Berg Properties.  Approximately  $39
million of debt was  outstanding  as of September 30, 1998 under the Wells Fargo
Line,  which  is  secured  by 14  properties.  See  "BACKGROUND  OF  THE  UPREIT
TRANSACTIONS--Consequences  of the Berg  Acquisition and the Private  Placement"
and "DESCRIPTION OF THE PROPERTIES--Mortgage Debt and Credit Lines."

BUSINESS OBJECTIVES AND STRATEGY

     After  completing  the UPREIT  Transactions,  the Company will operate as a
self-managed,  self-administered  and fully  integrated  REIT.  The Company will
operate the Berg  Properties and may acquire  additional R&D Properties from the
Berg Group under the terms of the Pending Projects Acquisition Agreement and the
"Option  Agreement."  The Company may also seek to acquire other R&D  properties
and other real estate assets in Silicon Valley and parts of the West Coast.  See
"FUTURE OPERATIONS."

OPERATIONS OF THE COMPANY AFTER THE BERG ACQUISITION, REINCORPORATION MERGER AND
THE REIT ELECTION

     Following  the  completion  of the UPREIT  Transactions,  the Company  will
occupy  the same  offices as BBE in a  building  owned by Berg & Berg.  BBE is a
member of the Berg Group and currently provides real estate development services
for the Berg Group and their affiliates, as well as the Berg Properties. Several
current  employees  of BBE,  including  Carl E. Berg,  will be  employees of the
Company.  The Company will lease space from Berg & Berg and will  reimburse  BBE
for a portion of the office  overhead.  See "FUTURE  OPERATIONS--Operations  and
Management."

DISTRIBUTIONS

   
     As a REIT,  the Company  will pay  distributions  based upon an estimate of
cash  available  for   distribution   to  shareholders   ("Cash   Available  for
Distribution") with total annual dividends expected to equal at least 95% of the
Company's annual taxable income in accordance with applicable REIT requirements.
The Company expects to pay quarterly  distributions of approximately  $0.085 per
share of Common  Stock of record prior to the  ex-dividend  date with respect to
the third and fourth quarters of 1998. See "DISTRIBUTION POLICY."
    

REASONS FOR THE REINCORPORATION MERGER

     The board of directors  believes that the Maryland General  Corporation Law
("MGCL")  contains  provisions  conducive to the operation of a REIT. Many REITs
have incorporated in the State of Maryland,  and the board of directors believes
that this has provided state regulatory  authorities and courts in Maryland with
substantial  experience  in the  administration  and  governance  of REITs.  See
"REINCORPORATION MERGER."

CONDITIONS TO CONSUMMATION

     The Berg Acquisition  (other than the Partnership  Closing) and the Private
Placement  are  subject  to  shareholder  approval  and such  customary  closing
conditions as the accuracy of  representations  and  warranties,  the absence of
material  adverse  changes,   and  the  absence  of  litigation  to  enjoin  the
consummation of any of the UPREIT  Transactions.  The Reincorporation  Merger is
subject to similar closing  conditions and the effectiveness of the Registration
Statement. See "THE ACQUISITION AGREEMENT," and "THE REINCORPORATION MERGER."

BOARD OF DIRECTORS; MANAGEMENT

   
     In general,  the board of  directors  and  management  of the Company  will
remain the same after the Reincorporation Merger. The Company expects to add one
or two  additional  directors  before the end of 1998.  See  "MANAGEMENT  OF THE
COMPANY UPON CONSUMMATION OF THE BERG ACQUISITION".
    

CONFLICTS OF INTEREST

   
     The UPREIT  Transactions  entail a number of  conflicts  of  interest.  The
Operating  Partnerships and the Company currently are controlled by Carl E. Berg
and other Berg Group  members.  After the  UPREIT  Transactions,  the Berg Group
members will have two representatives on the board of directors (the "Berg Group
Board  Representatives"),  at least  one of whom  will be  required  to  approve
certain  material  transactions  involving the Company (the "Required  Directors
Approval"). In addition, Berg Group members, in the aggregate, will own, or have
the right  under  certain  circumstances  to  acquire,  shares  of Common  Stock
representing  82.73% of the total number of the Outstanding Shares (assuming the
exchange  of all  outstanding  L.P.  Units  for  Common  Stock),  subject  to an
aggregate ownership limit of 20% (the "Berg Group Ownership Limit"), as provided
in the Aquisition Agreement.  Consent of the Limited Partners holding a majority
of outstanding L.P. Units (the "L.P. Unit Majority"), principally the Berg Group
members, will be required for certain major transactions involving the Operating

                                       -5-

<PAGE>


Partnerships.  Furthermore,  the Company and the Operating Partnerships will, or
may,  acquire  certain  additional R&D Properties from members of the Berg Group
under the terms of the Pending  Projects  Acquisition  Agreement  and the Option
Agreement. Although Mr. Berg will be the Company's President and Chief Executive
Officer,  he will remain  involved in many other real estate and venture capital
activities.  Transactions between the Company or the Operating  Partnerships and
members of the Berg Group, or their affiliates, will be subject to approval by a
committee of directors who are  independent of the Berg Group (the  "Independent
Directors Committee").  Additionally,  Mr. Berg and certain other members of the
Berg Group could cause the  Operating  Partnerships  to call the notes issued by
the Company at the Partnership Closing if they have not been repaid prior to the
second anniversary of their issuance.  See "RISK FACTORS--Control of the Company
and the  Operating  Partnerships  by the  Berg  Group  and  Mr.  Berg--Potential
Conflicts  of  Interest  with the Berg  Group"  and  "DELAY IN  CLOSING  PRIVATE
PLACEMENT."
    

REQUIRED APPROVAL

     Only  holders  of  Common  Stock of record on  _________  __,  1998 will be
entitled to vote at the Special Meeting.  The affirmative vote of the holders of
a majority  of the  outstanding  shares of record is needed to ratify or approve
each of the  UPREIT  Transactions.  Broker  non-votes  and  abstentions  will be
counted as votes against the UPREIT Transactions.

DISSENTERS' RIGHTS

     Statutory  dissenters' rights under the California General  Corporation Law
(the "CGCL") are not available  with respect to any of the Proposals to be voted
upon at the Special Meeting.

ACCOUNTING TREATMENT

     The UPREIT Transactions have been accounted for as a purchase. Accordingly,
the costs of the  acquisition  were  allocated  to the  assets  and  liabilities
purchased  based upon their  respective fair values at the effective date of the
acquisition.   See  "ACCOUNTING  TREATMENT  OF  THE  BERG  ACQUISITION  AND  THE
REINCORPORATION MERGER."

TAX CONSEQUENCES OF THE UPREIT TRANSACTIONS

     The Berg  Acquisition  and the  Private  Placement  will not  result in the
recognition  of gain or loss by the  Company  or its  shareholders  for  federal
income tax purposes.

     The  Reincorporation  Merger is expected  to be a tax-free  reincorporation
transaction  within the meaning of Section  368(a)(1)(F) of the Internal Revenue
Code of 1986,  as  amended  (the  "Code").  Accordingly,  it will not  result in
taxable income or result in the recognition of gain or loss by the Company,  its
shareholders, or the holders of options to purchase Common Stock.

     Once the Company elects REIT status following the  Reincorporation  Merger,
the Company  generally may avoid income tax with respect to its income,  and the
shareholders  will be  subject  to  income  taxation  with  respect  to  certain
distributions from the Company. Graham & James LLP will provide a federal income
tax opinion to the Company in connection with the Reincorporation  Merger to the
effect, that for the Company's taxable year ending December 31, 1998, it will be
organized  and  able to  operate  in  conformity  with  the  REIT  qualification
requirements under the Code. See "FEDERAL INCOME TAX CONSIDERATIONS--Taxation of
the Company."

NEW COMMON STOCK

   
     In connection with the  Reincorporation  Merger,  the Company is exchanging
previously  issued and outstanding  securities of the Company for new securities
of Mission West-Maryland. The New Common Stock exchanged for Old Common Stock in
connection  with the  Reincorporation  Merger will  continue to be listed on the
AMEX.  Shares of New Common Stock  acquired by affiliates of the Company will be
subject to manner of sale, volume  restrictions,  and other requirements  (aside
from  holding  period)  imposed by Rule 144 and Rule 145(d)  promulgated  by the
Commission.  See "DESCRIPTION OF MISSION  WEST-MARYLAND  STOCK--Restrictions  on
Transfer." Shares of New Common Stock acquired by the purchasers in exchange for
their  shares of Common  Stock  acquired  in the Private  Placement  may be sold
pursuant to Rule 144 after one year or pursuant to the  Registration  Statement,
as amended,  at the option of the Company,  to permit  continued  resales by the
holders  thereof,  subject to  certain  limitations.  See "RISK  FACTORS--Shares
Eligible for Future Sale" and "THE SELLING SHAREHOLDERS." The Company intends to
file with the Commission a registration statement on Form S-8 to register shares
of Common Stock which have been  reserved for issuance for future  option grants
under the  Company's  employee  benefit  plans and  resales of any Common  Stock
issued under such employee benefit plans.

(1)  Per  share  calculations  do  not  consider  the  dilutive  effect  of  (i)
     59,479,633  L.P.  Units that may become  exchangeable  for shares of Common
     Stock;  and (ii) 605,000 shares of Common Stock issuable in connection with
     options  outstanding  under the 1997 Stock Option Plan. For purposes of the
     pro  forma  per  share  calculation,   these  securities  if  converted  or
     exercised, would have no effect on per share calculations.
    

(2)  Average  monthly  rental  revenue  per square foot has been  determined  by
     taking the base rent for the period, divided by the number of months in the
     period, and then divided by the total square feet of occupied space.

   
(3)  As defined by the National  Association  of Real Estate  Investment  Trusts
     ("NAREIT"),  FFO represents net income (loss) before  minority  interest of
     unitholders (computed in accordance with GAAP), excluding gains (or losses)
     from debt  restructuring  and sales of property,  plus real estate  related
     depreciation and amortization (excluding amortization of deferred financing
     costs and depreciation of non-real estate assets) and after adjustments for
     unconsolidated partnerships and joint ventures. Management considers FFO an
     appropriate  measure of performance  of an equity REIT because,  along with
     cash flows from operating  activities,  financing  activities and investing
     activities,  it provides  investors with an  understanding of the Company's
     ability to incur and service debt and make capital expenditures. FFO should
     not be  considered  as an  alternative  for  net  income  as a  measure  of
     profitability  nor is it  comparable  to cash flows  provided by  operating
     activities  determined in accordance  with GAAP.  FFO is not  comparable to
     similarly  entitled  items  reported by other REITs that do not define them
     exactly as the Company defines FFO. See "Distribution Policy."

</TABLE>
    
- -------------------
(1)  Average  monthly  rental  revenue  per square foot has been  determined  by
     taking the base rent for the period, divided by the number of months in the
     period, and then divided by the total square feet of occupied space.

   
(2)  As defined by the National  Association  of Real Estate  Investment  Trusts
     ("NAREIT"),  FFO represents net income (loss) before  minority  interest of
     unitholders (computed in accordance with GAAP), excluding gains (or losses)
     from debt  restructuring  and sales of property,  plus real estate  related
     depreciation and amortization (excluding amortization of deferred financing
     costs and depreciation of non-real estate assets) and after adjustments for
     unconsolidated partnerships and joint ventures. Management considers FFO an
     appropriate  measure of  performance  of an equity REIT because, along with
     cash flows from operating  activities,  financing  activities and investing
     activities,  it provides  investors with an  understanding of the Company's
     ability to incur and service debt and make capital expenditures. FFO should
     not be  considered  as an  alternative  for  net  income  as a  measure  of
     profitability  nor is it  comparable  to cash flows  provided by  operating
     activities  determined in accordance  with GAAP.  FFO is not  comparable to
     similarly  entitled  items  reported by other REITs that do not define them
     exactly as the Company defines FFO. See "Distribution Policy."
    

(3)  Non-cash  adjustments to FFO were as follows: in all periods,  depreciation
     and amortization;  in 1996, 1995 and 1993, gains on extinguishment of debt;
     and in 1995, gain on sale of property.

                                  RISK FACTORS

     PROSPECTIVE  INVESTORS  SHOULD  CAREFULLY  CONSIDER THE FOLLOWING  RISKS IN
EVALUATING  THE  PROPOSALS.  THIS PROXY  STATEMENT/PROSPECTUS  CONTAINS  CERTAIN
FORWARD-LOOKING  STATEMENTS  THAT  INVOLVE  RISKS  AND  UNCERTAINTIES,  SUCH  AS
STATEMENTS  OF  THE  COMPANY'S  PLANS,  OBJECTIVES,  EXPECTATIONS,  BELIEFS  AND
INTENTIONS.  THE CAUTIONARY  STATEMENTS MADE IN THIS PROXY  STATEMENT/PROSPECTUS
SHOULD BE READ AS BEING  APPLICABLE  TO ALL RELATED  FORWARD-LOOKING  STATEMENTS
WHEREVER THEY APPEAR IN THIS PROXY  STATEMENT/PROSPECTUS.  THE COMPANY'S  ACTUAL
RESULTS   COULD   DIFFER   MATERIALLY   FROM  THOSE   DISCUSSED  IN  THIS  PROXY
STATEMENT/PROSPECTUS. FACTORS THAT COULD CAUSE OR CONTRIBUTE TO SUCH DIFFERENCES
INCLUDE THOSE DISCUSSED BELOW AND IN OTHER PLACES INCLUDING THE "THE BUSINESS OF
BERG & BERG,"  "MANAGEMENT'S  DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATION FOR THE PROPERTIES," AND "DISTRIBUTION POLICY."

NO INDEPENDENT APPRAISAL; NO ARM'S LENGTH NEGOTIATIONS WITH AFFILIATES

   
     There has been no independent valuation of the Company, nor have there been
any  discussions  or  negotiations   between  the  Berg  Group  and  independent
representatives of the Company concerning obtaining an independent valuation. In
October  1997,  the board of  directors  of the Company  determined  that future
transactions involving equity securities of the Company would be priced at $4.50
per share, or the equivalent thereof,  until the Company had acquired assets and
generated  revenues  and FFO.  That  price  was not  determined  by  independent
valuation  and no third party  appraisals  of the  Properties  were obtained for
purposes of the Private Placement,  or the Berg Acquisition,  nor has a fairness
opinion been  obtained.  The  valuation of the Company  implied by the Company's
purchase of the 12.11% general partner  interests in the Operating  Partnerships
for $35.2 million (  approximately  $4.30 per share),  and the value of the L.P.
Units to be held by the Limited Partners,  may not accurately  reflect the value
of the Properties in the Operating Partnerships prior to the consummation of the
Berg  Acquisition.  See  "BACKGROUND  OF THE UPREIT  TRANSACTIONS--Valuation  of
Interests."

SUBSTANTIAL BENEFITS TO MR. BERG AND OTHER BERG GROUP MEMBERS

     As a result of the Berg  Acquisition,  the Company has acquired  control of
the Berg Properties, which had a total fair value of $439 million and book value
of $178 million at the date of the acquisition,  and all but approximately $57.8
million of debt owed to or  guaranteed by Mr. Berg and other members of the Berg
Group  has been  repaid  with  the  proceeds  of the  Prudential  Secured  Loan,
including debt incurred by the Operating  Partnerships to fund substantially all
of a $138.7  million  distribution  to members  of the Berg  Group  prior to the
Partnership  Closing.  Carl E.  Berg,  Clyde J.  Berg and the other  Berg  Group
members own, in the aggregate,  55,845,938 L.P. Units,  valued at  approximately
$251.3 million (at $4.50 per L.P. Unit).
    

DEPENDENCE ON MR. BERG

   
     The Company is substantially dependent upon the leadership of Mr. Berg, its
Chairman and Chief Executive Officer.  See "THE BUSINESS OF BERG & BERG--History
of Berg & Berg." Mr.  Berg will be managing  the  day-to-day  operations  of the
Company as Chairman and Chief  Executive  Officer and will devote a  significant
portion of his time to the affairs of the Company, including the formulation and
execution of the Company's growth and business development strategies.  Mr. Berg
has a number of other  business  interests  to which he devotes a portion of his
time, however. See "POTENTIAL CONFLICTS OF INTEREST." In particular, Mr. Berg is
an investor in a number of technology companies in the Silicon Valley, including
tenants of a few of the Berg Properties, and serves on the board of directors of
six such technology companies.  The Company believes that his active involvement
in the  technology  industry  provides  the Company  with  valuable  information
regarding  the  business  and  operations  of its tenants and their  present and
future  space  requirements,  as well as valuable  industry  contacts and tenant
referral sources. The Company believes that the loss of these benefits,  through
the loss of Mr. Berg's knowledge and abilities and their benefits,  could have a
material adverse effect on the Company.
    

CONTROL OF THE COMPANY AND THE OPERATING PARTNERSHIPS BY THE BERG GROUP

     Following the completion of the UPREIT  Transactions,  the Berg Group,  and
Mr. Berg who controls the Berg Group, will exercise significant control over the
operations and affairs of the Company, and therefore,  indirectly, the Operating
Partnerships.

   
     OWNERSHIP  INTEREST.  Following the completion of the UPREIT  Transactions,
members of the Berg Group will hold L.P. Units  representing an aggregate 82.52%
limited partnership interest in the Operating Partnerships,  and an aggregate of
82.73% of the  Outstanding  Shares,  (without regard to the Berg Group Ownership
Limit) taking into account  their  existing  share  ownership and their right to
exchange   L.P.   Units  for   Common   Stock   under   certain   circumstances.
Notwithstanding  the Berg Group Ownership Limit, these exchange rights will give
the members of the Berg Group  substantial  influence  over the  management  and
direction of the Company. Moreover, the Berg Group members also will possess the
following  material rights with respect to the governance of the Company and the
Operating  Partnerships.  See "PRINCIPAL  SHAREHOLDERS" and " -- Shares Eligible
for Future Sale."
    


                                           -9-

<PAGE>


     BOARD OF DIRECTORS REPRESENTATION.  Pursuant to the UPREIT Transactions the
Berg Group will acquire the right to nominate two  directors for election to the
board of  directors  (the "Berg  Group  Board  Representatives")  so long as the
members of the Berg Group together with their Affiliates (other than the Company
and the Operating  Partnerships)  own at least 15% of the total number of shares
of voting stock of the Company taking into account the  conversion,  exchange or
exercise of all outstanding warrants, options,  convertible securities and other
rights to acquire voting stock of the Company and all L.P. Units exchangeable or
redeemable for Common Stock or other voting stock of the Company (without regard
to any Ownership  Limit) (the  "Fully-Diluted"  number of shares).  In the event
such ownership falls below 15% but is at least 10%, the Berg Group will have the
right to nominate  one person for election to the board of  directors.  Mr. Berg
and Michael Anderson, Vice President and Chief Operating Officer of the Company,
will  constitute  the initial  Berg Group Board  Representatives.  The other two
directors on the current  four-person  board of directors  will be  unaffiliated
with the Berg Group (the "Independent Directors") and, together, will constitute
the Independent  Directors Committee of the board of directors.  See "MANAGEMENT
OF  THE  COMPANY  UPON  CONSUMMATION  OF  THE  BERG  ACQUISITION--Directors  and
Executive Officers," "OPERATING PARTNERSHIP AGREEMENT--Management," and "CERTAIN
PROVISIONS  OF  MARYLAND  LAW  AND  OF  MISSION   WEST-MARYLAND'S   CHARTER  AND
BYLAWS--The Board of Directors."

     SPECIAL BOARD VOTING PROVISIONS.  The Charter will provide that, until such
time as the Berg Group and their  Affiliates  (other  than the  Company  and the
Operating Partnerships) own less than 15% of the Fully-Diluted  number of shares
of Common Stock (the "Protective  Provisions  Expiration  Date"),  the vote of a
majority of the  directors  including  Mr. Berg or someone he has  designated to
replace  him as a director  (the  "Required  Directors")  shall be  required  to
approve  certain  fundamental  corporate  actions,  including  amendments to the
Charter or bylaws, and any merger, consolidation or sale of all or substantially
all of the assets of the Company or the Operating Partnerships. In addition, the
Mission  West-Maryland  bylaws  will  provide  that a quorum  must  include  the
Required Directors for any action at a meeting.  Also, the approval of more than
75% of the  entire  board  of  directors  will  be  required  to  approve  other
significant  transactions such as certain borrowings in excess of 50% of the sum
of (i) the total number of  Outstanding  Shares  multiplied  by the market price
(the  "Market  Price") of the Common  Stock plus (ii) the  Company's  total debt
("Total  Market  Capitalization");  and the  conduct of  business by the Company
other  than  through  the  Operating Partnerships.  Accordingly,  under  certain
circumstances  the Berg  Group or Mr.  Berg  could  prevent  the  Company or the
Operating  Partnerships from taking any of such actions. See "CERTAIN PROVISIONS
OF MARYLAND LAW AND OF MISSION  WEST-MARYLAND'S CHARTER AND BYLAWS--Board Quorum
and Special Voting Requirements."

     LIMITED PARTNER APPROVAL RIGHTS. Under the Operating Partnership Agreement,
the consent of holders of the L.P.  Unit  Majority also is required with respect
to a number  of  significant  actions,  including  amendments  to the  Operating
Partnership  Agreement and the issuance of limited partnership  interests having
senior rights with respect to the L.P. Units. In addition,  until the Protective
Provisions  Expiration  Date,  the  consent of the L.P.  Unit  Majority  will be
required  with  respect to other  matters,  including  actions and  transactions
similar  to  those  requiring  the  approval  of  the  Required  Directors.  See
"OPERATING   PARTNERSHIP   AGREEMENT--Management."   Taxable  sales  of  certain
Properties are subject to the consent, under certain circumstances,  of Mr. Berg
and Clyde J. Berg, or Kontrabecki,  as well. See "--Tax  Consequences of Sale of
Properties."

POTENTIAL CONFLICTS OF INTEREST WITH THE BERG GROUP

     Mr. Berg and other members of the Berg Group, who will possess  significant
rights  in the  Company  and  the  Operating  Partnerships,  have a  variety  of
interests  which  may  not  be  consistent  with  the  interests  of  the  other
shareholders  of the Company.  One such conflict  arises because the Company has
agreed to pay overhead  reimbursements  and rent to BBE and Berg & Berg totaling
approximately  $15,000 per month. The Acquisition  Agreement  specifies that any
increase in rent and overhead allocations and all other transactions between the
Company and Mr. Berg or other members of the Berg Group,  or between the Company
and any entity in which Berg Group members own directly or indirectly 5% or more
of the equity interests including the Operating  Partnerships,  must be approved
by the Independent  Directors  Committee,  and provides additional  restrictions
summarized  below relating to specific  matters where  conflicts may arise.  Mr.
Berg also has agreed to refer all his prospective  R&D Property  development and
acquisition  activities in Washington,  Oregon and California to the Company for
initial consideration. There can be no assurance that these restrictions will be
successful in eliminating the influence of such conflicts. If these restrictions
are not successful, decisions could be made that might fail to protect fully the
interests of all shareholders of the Company. Aside from these restrictions, Mr.
Berg and the other  members of the Berg Group are  entitled to freedom of action
under the terms of the Acquisition Agreement.

     EXCLUDED PROPERTIES.  Although the Company is succeeding to most of the R&D
Properties in which the Berg Group holds interests,  certain properties that are
not  managed by any member of the Berg Group or are not  material to the Company
(the  "Excluded   Properties")  are  not  being  contributed  to  the  Operating
Partnerships.  Members  of the  Berg  Group  will  continue  to  hold  ownership
interests in the Excluded  Properties  that are not contributed to the Operating
Partnerships.  One such Excluded Property is the Company's headquarters at 10050
Bandley Drive, Cupertino, California, which is owned by Berg & Berg, and used by
Mr. Berg as his principal  office and the principal  office of other  Affiliates
besides the Company. The other Excluded Properties (representing an aggregate of
approximately  270,000  rentable  square feet) are located in the Silicon Valley
and cannot be made  available to the Company by any of the Berg Group members as
part of the Berg  Acquisition  because  no Berg  Group  member  has the power to
include  such  property  in the Berg  Acquisition,  or because  the  property is
subject to  obligations  that  render  transfer  to the  Operating  Partnerships
impractical.  The Company does not expect that these  Excluded  Properties  will
compete with any of the Properties,  and none of them involve any common tenants
or common financing arrangements with the Properties.

     PENDING DEVELOPMENT  PROJECTS.  There are four Pending Development Projects
which represent a potential total of 12 R&D Properties agregating  approximately
one million rentable square feet. Under the Acquisition  Agreement,  the Company
and the owners of these  Projects  have agreed that the Company or the Operating
Partnerships  will acquire each  developed  R&D Property as it is completed  and
leased.  Under the  terms of the  Pending  Projects  Acquisition  Agreement  the
sellers of these  Properties  may elect to receive cash or L.P. Units at a value
of $4.50 per unit.  The purchase price for each Property will be adjusted at the
time of  transfer  based upon the ratio of the actual  monthly  rental  rate per
square  foot to the  projected  rental  rate per  square  foot set  forth in the
Pending  Projects  Acquisition  Agreement.  The Berg Group  members  who own the
Pending Development  Projects,  including Carl E. Berg, will determine the terms
of the leases for each  Property  prior to its transfer to the  Company.  Berg &
Berg has signed a lease with Microsoft for an approximately  515,000 square feet
facility to be  constructed  by Microsoft at L'Avenida  with a triple net rental
rate of $2.95 per square foot if and when the lease takes  effect.  In each case
the sellers'  determination of acceptable terms may differ materially from those
sought by an  independent  party.  See  "DESCRIPTION  OF THE  PROPERTIES  -- The
Pending Development Projects.
    

     BERG LAND  HOLDINGS.  The Berg Land Holdings will not be contributed to the
Operating  Partnerships.  The Company  and the  Operating  Partnerships  have an
option to purchase  properties  developed on the Berg Land  Holdings,  as well a
right of first  offer  relating  thereto,  pursuant  to the terms of the  Option
Agreement.   See  "DESCRIPTION  OF  PROPERTIES--Land   Holding  and  Development
Arrangements." If the Independent Directors Committee does not elect to exercise
its rights with  respect to some or all of the Berg Land  Holdings  and the Berg
Group subsequently  determines to develop such Holdings,  Carl E. Berg and other
members of the Berg Group may devote a substantial  amount of their time to such
development  activities,  and the  developed  Berg Land Holdings may compete for
available tenants with certain of the Properties.

     TAX  CONSEQUENCES OF SALE OF PROPERTIES.  Since most of the Properties have
unrealized  gain  attributable  to the difference  between fair market value and
adjusted tax basis in such  Properties  prior to the  Company's  purchase of its
general partner's interest, the sale of any of such Properties may cause adverse
tax  consequences to the Limited  Partners.  As a result,  the Limited  Partners
might not favor a sale of a Property even though such a sale could be beneficial
to  other  shareholders  of  the  Company.  Furthermore,  until  the  Protective
Provisions  Expiration Date, the Operating  Partnership  Agreement provides that
for a period of ten years  following  the closing of the Berg  Acquisition,  the
Operating   Partnerships  may  not  sell  or  otherwise  transfer  any  Property
designated by Mr. Berg or Clyde J. Berg in a taxable  transaction.  In addition,
Mr. Kontrabecki may designate that the Kontrabecki Properties may not be sold or
transferred in a taxable  transaction.  See "FEDERAL INCOME TAX CONSIDERATIONS--
Tax Aspects of the Operating Partnerships,"  "CERTAIN PROVISIONS OF MARYLAND LAW
AND MISSION  WEST-MARYLAND'S  CHARTER AND  BYLAWS"  and  "OPERATING  PARTNERSHIP
AGREEMENT--Management."

   
     TERMS OF TRANSFERS; ENFORCEMENT OF PARTNERSHIP AGREEMENT. Neither the terms
of transfers of the Berg Properties to the Operating Partnerships by the Limited
Partners nor the terms of the Operating  Partnership  Agreement were  determined
through arm's-length  negotiation.  Some Berg Group members in their capacity as
beneficial owners of the Acquired Properties also had a substantial  interest in
determining the terms and conditions of the transfers of the Acquired Properties
and the Pending  Development  Projects to the Operating  Partnerships.  The Berg
Group Board  Representatives  also may be subject to a conflict of interest with
respect to their obligations as directors of the Company to enforce the terms of
the Operating Partnership Agreement.

     RELATED PARTY DEBT. The Company is liable under loans payable to Berg Group
members or that may be  otherwise  declared  in default by Carl E. Berg or other
Berg  Group  members in the event the loans are not paid when due.  These  loans
include the Demand Notes and a loan of approximately $19 million payable to BBE,
which  is  secured  by  three   properties   and  matures  in  March  1999.  See
"DESCRIPTIONS  OF THE PROPERTIES -- Mortgage Debt and Credit Lines." The Company
believes  that it will be able to repay all such  loans with  proceeds  from the
Wells Fargo Line,  the Private  Placement or other  sources of working  capital.
There can be no assurance  that such proceeds will be available when the related
party debt is due, however,  and Mr. Berg or other Berg Group members could take
action to enforce the Company's repayment obligations.

DELAY IN CLOSING PRIVATE PLACEMENT

     The purchasers in the Private Placement agreed to purchase shares of Common
Stock in early May 1998.  The Company  cannot  close the  purchase  transactions
until it has received  shareholder  authorization for the issuance of the shares
at the Special Meeting in  ___________,  1998,  however.  Due to the substantial
delay in closing the transactions, the Company believes that some purchasers may
be unwilling to pay for their shares at the scheduled  closing date because they
may no longer have adequate  available  funds,  may not consider the purchase of
the shares to be a desirable  investment at that time, or for some other reason.
In  September  1998,  the  trustees  of a trust  which had  agreed  to  purchase
1,000,000  shares of Common  Stock  sent a letter to the  Company  stating  that
because the trust had not received a copy of the signed stock purchase agreement
was  withdrawing its offer to purchase the 1,000,000  shares.  The Company has a
signed stock purchase  agreement with the trust that the Company considers to be
a binding agreement. Nevertheless, the Company's management views that letter as
an indication that recent broad-based  declines in stock values,  including most
publicly-traded  REIT shares, may have caused investors to re-evaluate  previous
investment  decisions.  Although the Company  believes it can enforce all of the
stock purchase  agreements  executed by the purchasers in the Private Placement,
the  Company's  management  may decide not to pursue claims  against  defaulting
purchasers.

     In that event, the Company would need to find additional sources of capital
to pay the Demand  Notes.  Currently,  the Company's  management  intends to use
proceeds of the Wells Fargo Line, if available, to pay the balance of the Demand
Notes remaining after the final closing date for the Berg Acquisition.  Mr. Berg
and members of the Berg Group who control an L.P.  Unit Majority in three of the
Operating  Partnerships  may call the Demand  Notes to the extent not retired at
the date. However, if funds from the Wells Fargo Line are not available for this
purpose, Carl E. Berg and other Berg Group members who are Limited Partners have
agreed not to demand payment in excess of the Company's  available  funds at the
closing of the Private Placement,  notwithstanding provisions of the Demand Note
to the contrary.
    

CHANGES IN POLICIES WITHOUT SHAREHOLDER APPROVAL

     The  Company's  board  of  directors  will  determine  the  investment  and
financing  policies of the Operating  Partnerships and its policies with respect
to  certain  other  activities,   including  its  growth,  debt  capitalization,
distribution  and  operating  policies.  See  "POLICIES  WITH RESPECT TO CERTAIN
INVESTMENT ACTIVITIES." The board of directors has no present intention to amend
or revise these policies.  However, the board of directors may do so at any time
without a vote of the Company's  shareholders.  A change in these policies could
adversely affect the Company's financial condition or results of operations.

ANTI-TAKEOVER PROVISIONS

     Provisions of the Charter and bylaws of Mission  West-Maryland could delay,
defer or prevent a transaction  or a change in control of Mission  West-Maryland
(or other  transaction) that might involve a premium price for holders of Common
Stock or  otherwise  be in their  best  interest.  See  "CERTAIN  PROVISIONS  OF
MARYLAND LAW AND OF MISSION WEST-MARYLAND'S CHARTER AND BYLAWS."

REAL ESTATE INVESTMENT CONSIDERATIONS

     GENERAL.  Real property investments are subject to varying degrees of risk.
The investment  returns available from equity  investments in real estate depend
in large part on the amount of income earned and capital appreciation  generated
by the Properties as well as the related expenses incurred. If the Properties do
not generate  revenue  sufficient to meet operating  expenses,  debt service and
capital expenditures,  the Company's income and ability to make distributions to
its shareholders will be adversely affected. Income from the Properties may also
be adversely affected by general economic conditions,  local economic conditions
such  as  oversupply  of  commercial  real  estate,  the  attractiveness  of the
Properties to tenants,  competition from other available  rental  property,  the
ability of the Company to provide adequate maintenance and insurance,  the costs
of tenant  improvements,  leasing  commissions  and tenant  inducements  and the
potential of increased  operating costs  (including real estate taxes).  Various
significant  expenditures  associated with an investment in real estate (such as
mortgage payments, real estate taxes and maintenance expenses) generally are not
reduced when  circumstances  cause a reduction  in revenue from the  investment.
Income from  properties and real estate values also are affected by a variety of
other factors,  such as governmental  regulations and applicable laws (including
real estate,  zoning and tax laws), interest rate levels and the availability of
financing.

     ILLIQUIDITY  OF  REAL  ESTATE  INVESTMENTS.  Real  estate  investments  are
relatively  illiquid,  which  limits the ability of the  Operating  Partnerships
(and,  therefore,  the  Company) to  restructure  its  portfolio  in response to
changes in economic or other conditions.  See "OPERATING PARTNERSHIP AGREEMENT--
Management." In addition, the Properties are subject to fixed expenditures, such
as debt service, real estate taxes, and expenses for repairs,  maintenance,  and
operations that do not decline with reductions in income.  Such  illiquidity and
fixed  expenditures,  together  with other  factors  might impede the  Company's
ability to respond to adverse conditions. The Company's ability to make expected
distributions to shareholders also could be adversely effected as a result.

     GEOGRAPHIC  AND INDUSTRY  CONCENTRATION;  DEPENDENCE  UPON  SILICON  VALLEY
ECONOMY AND THE ELECTRONICS  INDUSTRY.  All of the Properties are located in the
southern portion of the San Francisco Bay Area commonly  referred to as "Silicon
Valley." Following a recessionary period which ended in 1993, the Silicon Valley
economy has grown  robustly and the reported  unemployment  rate for Santa Clara
County was 3.1% as of  December  31,  1997.  See "THE  BUSINESS OF BERG & BERG--
Regional  Economic  Profile." As a result of the strong Silicon Valley  economy,
values for the  Properties  and rents  payable  under new leases have  increased
substantially  since  1995.  Future  increases  in  values  and  rents  for  the
Properties  depend to a significant  extent on the health of the Silicon  Valley
economy.  All of the Properties are subject to existing leases with fixed rental
rates,  and a  material  downturn  in  the  Silicon  Valley  economy,  or in the
commercial  real estate market in Silicon Valley,  will not  immediately  reduce
revenues but could have a material  adverse impact on the value of the Company's
Common Stock and on the Company's financial condition.  Following the completion
of UPREIT  Transactions,  the Company will consider expansion into other regions
of the West Coast with concentrations of technology  companies if R&D Properties
of good quality can be obtained on reasonable  terms. See "FUTURE  OPERATIONS OF
THE COMPANY--Acquisitions."

                                           -12-
<PAGE>

     RISK OF LOSS OF KEY TENANTS.  Most of the Properties are occupied by single
tenants,  many of whom are large,  publicly-traded  electronics  companies.  The
Company's  three  largest  tenants,   Apple  Computer  Inc.  ("Apple"),   Amdahl
Corporation  ("Amdahl"),   and  Cisco  Systems,  Inc.  ("Cisco")  accounted  for
approximately  16.25%, 8.67%, and 7.17%,  respectively,  of the aggregate Annual
Base Rent from the Berg  Properties  for the year ended  December 31, 1997.  The
Operating  Partnerships' 12 largest tenants for the Berg Properties represent at
least 56.8% of such Annual Base Rent. Eight of these tenants have occupied their
respective Properties for periods ranging from five to 22 years and have renewed
one or more  leases.  The  Company  believes  that  Berg &  Berg's  practice  of
emphasizing  the  development  of  single-tenant,   rather  than   multi-tenant,
Properties has  contributed to its relatively  high occupancy  rates.  Apple has
announced operating losses, internal reorganizations, and layoffs in each of its
last two fiscal years.  To date,  Apple has not defaulted in the payment of rent
under any of its three  leases with the  Operating Partnerships,  nor has Apple,
Amdahl or Cisco  notified the Operating Partnerships  of an intention to vacate,
reduce its occupancy at, or relocate  from any of their  respective  properties.
However,  there  can be no  assurance  that  Apple,  Amdahl,  Cisco or other key
tenants will renew their leases.  The Company  believes that it would be able to
relet  Properties of its other key tenants  should they be vacated and that some
of such Properties are currently  leased at below market rental rates.  However,
if the Company is unable to relet  properties  as leases  terminate or if Apple,
Amdahl,  Cisco or another key tenant were to terminate  their  tenancy,  and the
Company were unable to relet such Properties  within a reasonable period of time
and at comparable rental rates, the Company's  operating results and its ability
to make  distributions  could be adversely  affected.  See  "DESCRIPTION  OF THE
PROPERTIES--the Berg Properties."

     RISK OF BANKRUPTCY OF KEY TENANTS.  At any time, a tenant of the Properties
may seek the  protection  of the  bankruptcy  laws  which  could  result  in the
rejection and  termination  of such tenant's lease and thereby cause a reduction
in the Company's income. Although the Operating Partnerships'  predecessors have
experienced losses from tenant  bankruptcies of less than $25,000 since 1987, no
assurance can be given that tenants will not file for  bankruptcy  protection in
the future or, if a tenant  makes such a filing,  that it will  affirm its lease
and continue to make rental payments in a timely manner. In addition,  from time
to time a tenant may  experience a downturn in its business which may weaken its
financial  condition and result in its failure to make rental payments when due.
If a tenant's  lease is not  affirmed  following a  bankruptcy  filing,  or if a
tenant's  financial  condition  weakens,  the Company's  income may be adversely
affected.  The bankruptcy of one or more of the Company's key tenants could have
a material adverse effect on the Company's  operating results and its ability to
make distributions.

     ADDITIONAL RISKS OF REAL ESTATE ACQUISITION AND DEVELOPMENT. A focus of the
Company  will  be  the   acquisition   of  additional   properties  in  selected
geographical  areas and the  renovation  and reletting of such  properties.  The
Company may also  undertake the  development  of new buildings on sites acquired
from the Berg Group or from third parties.  See  "DESCRIPTION  OF THE PROPERTIES
- -Land  Holding  and  Development  Arrangements."  Real  estate  acquisition  and
development  involves  significant  risks in addition  to those  relating to the
ownership  and  operation of existing,  fully-leased  properties,  including the
risks that  required  approvals  may not be  obtained  or may take more time and
resources to obtain than  expected,  that  construction  may not be completed on
schedule or on budget and that the properties may not achieve  anticipated  rent
or occupancy levels.  In addition,  if permanent debt or equity financing is not
available  on  acceptable  terms to  refinance  new  development  activities  or
acquisitions   undertaken  without  permanent  financing,   further  development
activities  or  acquisitions  could be  curtailed  and the  Company's  operating
results and its ability to make distribution could be adversely affected.

   
     DEBT FINANCING;  RISK OF INABILITY TO SERVICE DEBT. On a pro forma basis as
of September 30, 1998,  after giving effect to the Berg  Acquisition,  45 of the
Properties are mortgaged to secure  payment of debt, and the Company  expects to
have outstanding  approximately $223 million of debt secured by such Properties.
If the Operating  Partnerships  were unable to meet their mortgage  payments,  a
loss  could be  sustained  as a result of  foreclosure  on its  Property  by the
mortgagee. Such a loss could reduce the value of the Company's investment in the
Operating Partnerships.  See "DESCRIPTION OF THE PROPERTIES -- Mortgage Debt and
Wells  Fargo  Line"  for  information  regarding  the  terms  of  the  mortgages
encumbering the Properties.

     As part of its current business strategy,  the Company has adopted a policy
of maintaining a consolidated  ratio of Debt to Total Market  Capitalization  of
less than 50%,  which may not be exceeded  without the approval of more than 75%
of the entire board of directors. The Company's pro forma ratio of Debt to Total
Market  Capitalization  would have been approximately 42% at September 30, 1998,
assuming  the  occurrence  of the UPREIT  Transactions,  a Market Price of $4.50
price per share,  and 67,673,227  Outstanding  Shares issued and  outstanding on
that date.  Within the prescribed  limit,  the board of directors of the Company
may, from time to time,  modify its debt policy and may increase or decrease its
ratio of Debt to Total Market Capitalization.  If the Company were to change its
debt policy,  the Company  could become more highly  leveraged,  resulting in an
increased  risk of default on its  obligations  and an increase in debt  service
requirements that could adversely affect the Company's financial condition,  its
operating results and its ability to make distributions.
    

                                           -13-

     POTENTIAL ENVIRONMENTAL  LIABILITY.  Under various federal, state and local
laws,  ordinances and regulations,  an owner or operator of real property may be
held  liable for the costs of removal or  remediation  of certain  hazardous  or
toxic substances located on or in the property. Such laws often impose liability
and expose the owner to governmental  proceedings  without regard to whether the
owner knew of, or was  responsible  for, the presence of the  hazardous or toxic
substances.  The cost of any required  remediation or removal of such substances
may be  substantial.  In  addition,  the owner's  liability  as to any  specific
property is  generally  not limited and could  exceed the value of the  property
and/or the aggregate assets of the owner.  The presence of such  substances,  or
the failure to properly remove or remediate such substances,  may also adversely
affect the owner's  ability to sell or rent the  property or to borrow using the
property as  collateral.  Persons who arrange for  treatment  or the disposal of
hazardous or toxic  substances  may also be liable for the costs of any required
remediation  or  removal  of the  hazardous  or toxic  substances  at a disposal
facility,  regardless of whether the facility is owned or operated by such owner
or entity.  In connection  with the ownership of the Properties or the treatment
or disposal of hazardous or toxic substances, the Company may be liable for such
costs.

     Other  federal,  state and local laws impose  liability  for the release of
asbestos-containing  materials  ("ACMs") into the air and require the removal of
damaged ACMs in the event of remodeling or renovation. The Company is aware that
there  are  ACMs  present  at  several  of the  Properties,  primarily  in floor
coverings.  The Company  believes that the ACMs present at these  Properties are
generally  in good  condition  and that no ACMs  are  present  at the  remaining
Properties.  The Company  believes it is in compliance in all material  respects
with all present  federal,  state and local laws relating to ACMs and that if it
were given limited time to remove all ACMs present at the  Properties,  the cost
of such  removal  would not have a  material  adverse  effect  on its  financial
condition, operating results or ability to make distributions.

     The  Company is not aware of any  environmental  liability  relating to the
Properties  that  it  believes  would  have a  material  adverse  effect  on its
financial condition,  its operating results or its ability to make distributions
and has not been notified by any  governmental  authority or any other person of
any material  noncompliance,  liability or other claim in connection with any of
the   Properties.   Groundwater   contaminated  by  chemicals  used  in  various
manufacturing  processes,  including  semiconductor  fabrication,   underlies  a
significant  portion  of  northeastern  Santa  Clara  County,  where many of the
Properties  are  located,  however.  Environmental  assessments  have  not  been
conducted for most of the Properties and none since 1995.  Phase I environmental
assessments and some soil and water sampling as recommended by the environmental
consultant have been obtained on each of the Pending  Development  Projects.  No
assurance  can be given that future uses and  conditions  (including  changes in
applicable  environmental  laws and  regulations,  the uses  and  conditions  of
properties  in the  vicinity  of the  Properties,  such as  leaking  underground
storage tanks and the current and future  activities of tenants) will not result
in the imposition of environmental liability and the costs attendant thereto.

   
     GENERAL   UNINSURED   LOSSES.   The  Operating   Partnerships   will  carry
comprehensive  liability,  fire,  extended  coverage  and rental loss  insurance
covering all of the Properties,  with policy  specifications  and insured limits
which the Company believes are adequate and appropriate under the circumstances.
There are, however, certain types of extraordinary losses that are not generally
insured  because  they are either  uninsurable  or not  economically  insurable.
Should an  uninsured  loss or a loss in  excess of  insured  limits  occur,  the
Operating  Partnerships could lose their capital invested in a Property, as well
as the anticipated  future revenues from the Property,  and, in the case of debt
which is recourse to the Operating Partnerships,  would remain obligated for any
mortgage  debt or other  financial  obligations  related  to the  Property.  The
Company does not intend to obtain  owner's title  insurance  policies for any of
the Properties, but pursuant to the Acquisition Agreement certain members of the
Berg Group and other  Limited  Partners have agreed to indemnify the Company for
any losses attributable to defects in title existing prior to the closing of the
Berg Acquisition. If a loss occurs resulting from a title defect with respect to
a Property  in excess of insured  limits,  or the  Company  cannot  obtain  full
recovery though the Berg Group's  indemnification where applicable,  the Company
could lose all or part of its  investment in, and  anticipated  profits and cash
flows from, such Property.
    

                                    -14-
<PAGE>

   
     POTENTIAL  UNINSURED LOSSES FROM SEISMIC  ACTIVITY.  All the Properties are
located  in areas  that are  subject to  earthquake  activity.  In light of such
earthquake  risk,  since  the  early  1970's,  California  building  codes  have
established  construction standards for all newly built and renovated buildings,
the current and most strict construction  standards having been adopted in 1994.
Most of the Properties  were  completed  prior to the adoption of more stringent
building  codes  in  1994.  The  Company   believes  that  all  Properties  were
constructed in full compliance with applicable laws and  construction  standards
existing at the time of  construction.  The  Operating  Partnerships'  insurance
policies for the Berg Properties do not cover damage caused by seismic activity,
although  they do cover  losses from fires after an  earthquake.  The  Operating
Partnership have not obtained earthquake  insurance for the Properties,  and the
Company  believes  that such  insurance  coverage is generally  not  economical.
Following  the October 17, 1989 Loma Prieta  earthquake in the San Francisco Bay
Area,  which had a magnitude of approximately  7.1 on the Richter scale,  Berg &
Berg observed, and its tenants reported,  only minimal damage to the Properties.
Should an earthquake  occur that results in  substantial  damage to the existing
Properties,  or  properties  subsequently  acquired by the Company,  the Company
could  lose its  investment  in such  properties  and its  financial  condition,
operating results and ability to make distributions could be adversely affected.
    

FEDERAL INCOME TAX RISKS

     FAILURE TO QUALIFY AS A REIT. The Company intends to elect to be taxed as a
REIT under the Code for its  taxable  year  ending  December  31,  1998,  and to
operate in a manner  designed to achieve and maintain  qualification  as a REIT.
Although  the Company  expects  that it will be  organized  and will  operate in
conformity with the requirements  for  qualification as a REIT, no assurance can
be given that the Company will so qualify or that it will continue to qualify in
the future. Qualification as a REIT involves the application of highly technical
and complex  Code  provisions  for which  there are only  limited  judicial  and
administrative  interpretations.  The Company's  ability to qualify and maintain
its  status  as a REIT will  depend on the  Company's  ability  to meet  various
requirements.  For example,  at least 95% of the  Company's  gross income in any
year must be derived from dividends, interest, rents from real property, certain
capital  gains and other  qualified  sources,  and the Company  must make annual
distributions  to shareholders  totaling at least 95% of its REIT taxable income
(excluding net capital gains).  See "FEDERAL INCOME TAX  CONSIDERATIONS."  These
and various  other factual  matters and  circumstances  not entirely  within the
Company's  control may affect its ability to qualify or maintain its status as a
REIT. In addition, no assurance can be given that new legislation,  regulations,
administrative  interpretations or court decisions will not significantly change
the tax laws with respect to  qualification  as a REIT or the federal income tax
consequences    of    such    qualification.    See    "FEDERAL    INCOME    TAX
CONSIDERATIONS--Requirements for Qualification."

     If the Company  were to fail to qualify as a REIT in any taxable  year,  it
would not be  allowed a  deduction  for  distributions  to its  shareholders  in
computing  its  taxable  income,  and it would be subject to federal  income tax
(including  any  applicable  alternative  minimum tax) on its taxable  income at
regular   corporate  rates.   Unless  entitled  to  relief  under  certain  Code
provisions,  the Company would also be disqualified from treatment as a REIT for
the four taxable years  following the year during which REIT  qualification  was
lost. As a result of the loss of REIT status,  funds available for  distribution
to the Company's  shareholders  would be reduced for each of the years  involved
and, in addition,  the Company would no longer be required to make distributions
to its  shareholders.  Although  the Company  currently  intends to operate in a
manner designed to enable it to qualify and maintain its status as a REIT, it is
possible that economic, market, legal, tax or other considerations may cause the
Company  to fail to  qualify  as a REIT or may  cause  the  Company's  board  of
directors  either to refrain from making the REIT election or to revoke the REIT
election once made.

     REIT  DISTRIBUTION  REQUIREMENTS.  To obtain  and  maintain  favorable  tax
treatment  as a REIT,  the  Company  generally  will be  required  each  year to
distribute  as a  dividend  to its  shareholders  at least 95% of its  otherwise
taxable income (after  certain  adjustments).  In addition,  the Company will be
subject to a 4% nondeductible excise tax on the amount, if any, by which certain
distributions paid by it with respect to any calendar year are less than the sum
of 85% of its  ordinary  income for the calendar  year,  95% of its capital gain
income for the calendar  year and any  undistributed  taxable  income from prior
periods. Failure to comply with these requirements would result in the Company's
income being subject to tax at regular corporate rates.

     OWNERSHIP LIMIT NECESSARY TO MAINTAIN REIT QUALIFICATION.  In order for the
Company to maintain its  qualification  as a REIT, not more than 50% in value of
its  outstanding  stock may be owned,  directly or indirectly,  by five or fewer
individuals, as defined in the Code (the "Five or Fewer Test"). For the purposes
of  preserving  the Company's  qualification  as a REIT,  the Charter  generally
prohibits  ownership (the "Ownership Limit") of more than 9% of the Common Stock
by any shareholder (other than limits set by agreements with the Berg Group, for
which the aggregate  Ownership Limit is 20% (the "Berg Group Ownership Limit")).
The Charter  mandates the  aggregation  of stock owned by affiliated  owners for
purposes of the Ownership Limit.  Individuals  owning a percentage of the Common
Stock  outstanding  that  exceeds  the  Ownership  Limit  at  the  time  of  the
Reincorporation  Merger will not be required to reduce their stock  holdings but
will be  subject to the  Ownership  Limit with  respect  to the  acquisition  of
additional  shares of Common  Stock  (other  than  shares  acquired  pursuant to
board-approved   stock   option  and  other   compensation   plans).   Following
consummation of the UPREIT Transactions,  the Berg Group initially will own less
than two  percent  of the issued  and  outstanding  Common  Stock.  One  current
legislative  proposal of the  Clinton  administration  would amend the  "closely
held"   requirement   for  REIT   qualification.   See   "FEDERAL   INCOME   TAX
CONSIDERATIONS--Requirements for Qualification."

     The  constructive  ownership  rules of the Code are  complex  and may cause
Common Stock owned,  directly or indirectly,  by a group of related  individuals
and/or  entities to be deemed to be  constructively  owned by one  individual or
entity. As a result, the acquisition of less than 9% of the Common Stock (or the
acquisition  of  an  interest  in an  entity  which  owns  Common  Stock)  by an
individual  or  entity  could  cause  that  individual  or  entity  (or  another
individual or entity) to own constructively in excess of 9% of the Common Stock,
and thus subject such stock to the Ownership Limit.

     The  Charter  provides  that any  transfer of shares by members of the Berg
Group  or other  shareholders  that  would  result  in  direct  or  constructive
ownership in excess of the  applicable  Ownership  Limit would be void,  and the
intended transferee of such shares,  including any pledgee, will be deemed never
to have had an interest in such shares. Further, if, in the opinion of the board
of  directors  (i) a  transfer  or  repurchase  of  shares  would  result in any
shareholder or group of  shareholders  acting  together  owning in excess of the
Ownership  Limit,  or (ii) a  proposed  transfer  or  repurchase  of shares  may
jeopardize the  qualification of the Company as a REIT under the Code, under the
Charter the board of directors may, in its sole discretion,  refuse to allow the
shares  to be  transferred  to  the  proposed  transferee.  If any  transfer  or
repurchase of shares of Common Stock occurs which, if effective, would result in
any person beneficially or constructively  owning shares of Stock of the Company
in excess or in violation  of the above  transfer or  ownership  limitations  (a
"Prohibited  Owner"),   then  that  number  of  shares  shall  be  automatically
transferred  to a trust (the "Trust") for the  exclusive  benefit of one or more
charitable  beneficiaries  (the  "Charitable  Beneficiary"),  and the Prohibited
Owner shall not acquire any rights in such shares.  The  Prohibited  Owner shall
not  benefit  economically  from  ownership  of any  shares of stock held in the
Trust,  shall have no rights to  dividends  and shall not  possess any rights to
vote or other rights  attributable to the shares of stock held in the Trust. The
trustee of the Trust (the "Trustee")  shall have all voting rights and rights to
dividends  or other  distributions  with  respect to shares of stock held in the
Trust,  which  rights  shall  be  exercised  for the  exclusive  benefit  of the
Charitable Beneficiary.  The shares or L.P. Units held by the Berg Group members
are not subject to  automatic  transfer to the Trust,  however,  as their shares
will be subject to the  prohibitions  associated  with the applicable Berg Group
Ownership  Limit,  as well as  restrictions  on any exchanges of L.P.  Units and
share  purchases,  repurchases  and transfers of any kind that would result in a
violation   of   the   Five   or   Fewer   Test.   See   "FEDERAL   INCOME   TAX
CONSIDERATIONS--Requirements for Qualification."

UNCERTAINTIES REGARDING DISTRIBUTIONS TO SHAREHOLDERS

     The Company's  income will consist  primarily of the Company's share of the
income of the Operating Partnerships,  and the Company's  cash flow will consist
primarily  of  its  share  of  distributions  from  the  Operating Partnerships.
Differences  in timing between the receipt of income and the payment of expenses
in arriving at taxable income (of the Company or the Operating Partnerships) and
the effect of required  debt  amortization  payments  could  require the Company
directly, or through the Operating Partnerships, to borrow funds on a short-term
basis to meet its intended distribution policy. See "MANAGEMENT'S DISCUSSION AND
ANALYSIS   OF   FINANCIAL   CONDITION   AND  RESULTS  OF   OPERATIONS   FOR  THE
PROPERTIES--Liquidity  and  Capital  Resources"  and  "DISTRIBUTION  POLICY" for
information concerning the Company's expected cash flow.

                                      -16-
<PAGE>


     The amount and timing of distributions by the Operating  Partnerships  will
be  determined  by the board of  directors  of the  Company as the sole  general
partner  of the  Operating  Partnerships  and will be  dependent  on a number of
factors, including the amount of cash available for distribution,  the Operating
Partnerships'  financial  condition,  any  decision by the Board of Directors to
reinvest funds rather than to distribute such funds, the Operating Partnerships'
capital  expenditures,  the  annual  distribution  requirements  under  the REIT
provisions  of the  Code  and  such  other  factors  as the  Company's  Board of
Directors deems relevant.  See "FEDERAL INCOME TAX  CONSIDERATIONS--Taxation  of
the   Company--Requirements   for  Qualification"  and  "--Annual   Distribution
Requirements." Accordingly,  there is no assurance that the Company will be able
to meet or maintain its intended distribution policy.

POTENTIAL PROPERTY TAX REASSESSMENTS

     The Company  does not believe  that its  acquisition  of  interests  in the
Operating  Partnerships  will result in a statutory  change in ownership  giving
rise to a reassessment  of any of the  Properties  for  California  property tax
purposes. There can be no assurance, however, that county assessors or other tax
administrative  agencies  in  California  will not attempt to assert that such a
change occurred as a result of the transactions related to the Berg Acquisition.
Although  the Company  believes  that such a challenge  would not be  successful
ultimately,  there can be no assurance regarding the outcome of any such dispute
or proceeding.  Such a reassessment  could result in increased real estate taxes
on the Properties.  Substantially  all of the leases for the Properties  contain
provisions  requiring  the  tenants  to pay  their  proportionate  share  of any
property tax increases. As a practical matter, the Company may be unable to pass
through to its tenants the full amount of the increased  taxes  resulting from a
reassessment,  however,  the Company believes that any amount not passed through
to tenants will not have a material effect on the Company's  operating  results.
See "THE COMPANY'S PRO FORMA DATA."

MARKET FOR COMMON STOCK

     The AMEX  halted  trading of the Common  Stock at the opening of trading on
October 20,1997. The last day of trading prior to the halt was October 17, 1997.
The  closing  price of the  Common  Stock on  October  17,  1997 was  $3.38.  On
_____________, 1998, the last trading day immediately preceding the date of this
Proxy  Statement/Prospectus,  the closing  price of the Common Stock on the AMEX
was $________.

THE COMPANY'S OBLIGATION TO PURCHASE TENDERED L.P. UNITS

     Each of the  Limited  Partners  (other than Carl E. Berg and Clyde J. Berg)
will have the annual right to exercise  their Put Rights and cause the Operating
Partnerships to purchase a portion of their L.P. Units at a purchase price based
on the average  market value of the Common Stock for the  10-trading  day period
immediately preceding the date of tender. Upon the exercise of this put right by
a Limited Partner the Company will have the option to purchase the tendered L.P.
Units with available  cash,  borrowed  funds,  or the proceeds of an offering of
newly issued shares of Common Stock. The Limited  Partners' Put Rights generally
commence  one  year  after  the  completion  of the  Berg  Acquisition,  and are
available  once a year for a maximum of one-third of the Limited  Partner's L.P.
Units.  If the total  purchase  price of the L.P.  Units tendered by all Limited
Partners  in one year  exceeds $1 million,  the  Operating  Partnerships  or the
Company shall be entitled to reduce  proportionally  the number of L.P. Units to
be acquired from each tendering Limited Partner so that the total purchase price
is not more than $1  million.  The  exercise  by Limited  Partners  of their Put
Rights may reduce the amount of Cash Available for  Distribution to shareholders
of the Company.  See  "OPERATING  PARTNERSHIP  AGREEMENT--Exchange  Rights,  Put
Rights and Registration Rights."

RISK OF POTENTIAL SECURITIES LAW VIOLATIONS

   
     The offer and sale of L.P. Units by the Operating Partnerships has not been
registered  under the  Securities  Act,  in  reliance  upon the  exemption  from
registration provided by Section 4(2) of the Securities Act for "transactions by
an issuer not involving any public offering." Although the Acquisition Agreement
contemplating  the  issuance of the L.P.  Units and Common  Stock of the Company
issuable  on  conversion  of the  L.P.  Units  after  one year  pursuant  to the
Acquisition   Agreement   was  entered  into  by  the  Company,   the  Operating
Partnerships  and the Limited  Partners prior to the filing of the  Registration
Statement with the Commission,  the closing of the  transactions  comprising the
Berg  Acquisition had not occurred prior to such filing.  Accordingly,  an issue
may arise under the federal  securities laws as to whether the offer and sale of
L.P.  Units to the  Limited  Partners  should be  integrated  with the  offering
contemplated in connection with the Reincorporation  Merger with the effect that
the  exemption  afforded  by  Section  4(2)  of  the  Securities  Act  would  be
unavailable, and the offer and sale of L.P. Units to the Limited Partners should
have been registered under the Securities Act. If it were ultimately  determined
that the offer and sale of L.P. Units to the Limited  Partners  should have been
registered  under the  Securities  Act, the holders of L.P. Units might have the
right under the federal securities laws to rescind the sales of these securities
and  contributions  of certain R&D  Properties  by such  Limited  Partners;  or,
theoretically,  even to seek  rescission  of the  Company's  acquisition  of its
general  partner  interests in the Operating  Partnerships.  As Carl E. Berg has
agreed with the  Company  that  neither he nor any other Berg Group  member will
take any such action  against the  Operating  Partnerships  or the Company,  the
Company  believes  that  any  claim  of  non-compliance  with  the  registration
provisions of the  Securities Act with respect to the offer and sale of the L.P.
Units is unlikely and does not believe that any such potential  securities  laws
violations will materially  adversely affect the Company's  financial  position,
results of  operations  or ability to make  distributions  to  stockholders.  In
addition,  the Company has  received  the opinion of counsel to the Company that
such  offers and sales  were  exempt  from the  registration  provisions  of the
Securities Act.

SHARES ELIGIBLE FOR FUTURE SALE

   
     No  prediction  can be made as to the effect,  if any, that future sales of
shares,  or the  availability of shares for future sale, will have on the market
price of the  Common  Stock.  Sales  of  substantial  amounts  of  Common  Stock
(including  shares  issued  in  connection  with  the  Exchange  Rights)  or the
perception that such sales could occur, could adversely affect prevailing market
prices for the Common Stock.  Additional shares of Common Stock may be issued to
the Limited  Partners  (subject to the Ownership  Limit) if they exchange  their
L.P. Units for shares of Common Stock pursuant to the Exchange  Rights or may be
sold by the  Company to raise  funds to acquire  such L.P.  Units if the Limited
Partners elect to tender L.P.  Units to the Company  pursuant to the Put Rights.
Such Exchange Rights and Put Rights, however, generally are not available during
the first 12 months  following  the Berg  Acquisition.  During that period,  the
Limited  Partners  will be  allowed  to seek one  registration  of not more than
500,000  shares of Common  Stock for resale (on SEC Form S-3 or the  equivalent)
and will have "piggyback registration" rights for not more than 25% of the total
number of shares  proposed for a public offering of Common Stock by the Company.
Following the first  anniversary  of the Berg  Acquisition,  the exercise of the
Exchange  Rights  generally  is limited to the  exchange or sale once during any
12-month  period by each Limited  Partner of up to  one-third  of the  aggregate
number of L.P.  Units  owned by such  Limited  Partner.  The Company has granted
certain "demand," "resale" and "piggyback"  registration  rights with respect to
shares of Common Stock  acquired by the Limited  Partners  and their  Affiliates
pursuant to the  Exchange  Rights.  All  registrations  of Berg Group shares are
subject to underwriters' requirements for offering size reduction, and the right
of the  board of  directors  to  restrict  or delay  registrations  for  limited
periods. Purchasers of 6,495,058 shares of Common Stock in the Private Placement
will be  permitted  to sell from time to time the  shares  of New  Common  Stock
issued in exchange for those shares in the  Reincorporation  Merger  pursuant to
the Registration Statement and any post-effective  amendment to the Registration
Statement,  which the Company  will try to keep  effective  for one year,  until
those shares  become  eligible for sale  pursuant to Rule 144.  Their ability to
sell those  shares  pursuant to the  Registration  Statement  will be subject to
certain  restrictions,  including the Company's  right to require the holders of
the shares to halt further  offers and sales during periods when the Company has
determined  that the  continued  offer and sale of those shares  pursuant to the
Registration  Statement would be detrimental to the Company or its stockholders.
The Company may decide not to maintain  the  effectiveness  of the  Registration
Statement  during the first year  following  the final closing date for the Berg
Acquisition.  See "BACKGROUND OF THE UPREIT TRANSACTIONS -- Background" and "THE
SELLING STOCKHOLDERS." Sales of shares acquired by members of the Berg Group and
other  Limited  Partners  through  the  exercise  of their  Exchange  Rights and
registration  rights and  fluctuations in resales  pursuant to the  Registration
Statement may adversely  impact the price and trading volume of the Common Stock
from time to time to the detriment of other stockholders.

                               THE SPECIAL MEETING

     At the Special Meeting,  the board of directors seeks shareholder  approval
or  ratification  of the  following  six  proposals  pertaining  to  the  UPREIT
Transactions.  Each  of the  transactions  is  subject  to  distinct  terms  and
conditions.  The parties to the Berg  Acquisition have completed the Partnership
Closing  portion  of  the  transaction,   and  the  Company  seeks   shareholder
ratification of the Berg  Acquisition is conditioned  upon the completion of the
Private Placement. None of such transactions is subject to the occurrence of the
Reincorporation  Merger.  The board of directors intends for the shareholders to
consider  all  six  proposals  at  once,  and  this  Proxy  Statement/Prospectus
describes the UPREIT  Transactions and their material  consequences based on the
assumption  that  all  of  the  UPREIT  Transactions  will  be  approved  by the
shareholders and consummated by the parties to each transaction.

                                    PARTNERS
    


                                   PROPOSAL 6

                REINCORPORATION OF THE COMPANY AS A MARYLAND REIT

PROPOSALS  1, 2, 3, 4 AND 5 PERTAIN TO THE BERG  ACQUISITION  AND THE  COMPANY'S
FORMATION  OF AN  UPREIT.  PROPOSAL 6 CONCERNS  THE MERGER OF THE  COMPANY  INTO
MISSION  WEST-MARYLAND,  WHICH THE COMPANY ANTICIPATES WILL ELECT REIT STATUS IN
1998.

PARTIES TO THE BERG ACQUISITION

   
     The Berg  Group  consists  of Carl E.  Berg and his  wife,  Clyde J.  Berg,
certain trusts for their  respective  children,  BBE, and certain other entities
which they control. See "PRINCIPAL  SHAREHOLDERS." The members of the Berg Group
currently own 55,845,938 L.P. Units,  or  approximately  82.52% of the Operating
Partnerships.  The  remaining  3,633,695  L.P.  Units  are  owned  directly,  or
indirectly,  by Mr. Kontrabecki and other  non-Affiliates of the Berg Group. All
the individuals and entities  actually  holding or acquiring record ownership of
the L.P. Units  pursuant to the  Acquisition  Agreement have  represented to the
Company that they are accredited  investors within the meaning of Rule 501(a) of
Regulation D promulgated  by the Commission  under the Securities  Act. The Berg
Acquisition will provide material benefits to the members of the Berg Group. See
"BACKGROUND  OF THE  UPREIT  TRANSACTIONS--Benefits  to  the  Berg  Group,"  and
"Description of the Properties -- Overview of the Acquired Properties."
    

PARTIES TO THE REINCORPORATION MERGER

     The  Reincorporation  Merger  will be  effected  through  the merger of the
Company  with and into  Mission  West-Maryland  pursuant to Section  1110 of the
California  General  Corporation  Law (the "CGCL") and Sections 3-101 et seq. of
the Maryland General  Corporation Law (the "MGCL").  Mission  West-Maryland  was
incorporated in Maryland on March 20, 1998. See "THE REINCORPORATION MERGER."

GENERAL INFORMATION CONCERNING SOLICITATION AND VOTING

     The enclosed  proxy is solicited on behalf of the board of directors of the
Company for use at the Special  Meeting to be held on, or at any  adjournment or
postponement thereof, for the purposes set forth herein and in the

                                    -19-
<PAGE>

accompanying Notice of Special Meeting of Shareholders. The Special Meeting will
be held at 10050 Bandley Drive, Cupertino, California 95014. The mailing of this
Prospectus/Proxy Statement and the accompanying form of proxy to shareholders of
the Company  entitled to vote at the Special  Meeting is expected to commence on
or about ______________, 1998.

RECORD DATE, VOTING RIGHTS AND OUTSTANDING SHARES

   
     The outstanding  securities of the Company at October 15, 1998 consisted of
1,698,536  shares of Common Stock.  Each  shareholder  of record at the close of
business on  ___________,  1998 is entitled to one vote for each share of Common
Stock then held.  The shares  represented by any proxy in the enclosed form will
be voted in accordance with the instructions  given on the proxy if the proxy is
properly executed and is received by the Company prior to the close of voting at
the meeting or any adjournment or postponement thereof.
    

REVOCABILITY OF PROXIES

     A shareholder  giving a proxy has the power to revoke it at any time before
it is  exercised.  A proxy may be revoked by filing  with the  Secretary  of the
Company at the Company's  principal  executive  office at 10050  Bandley  Drive,
Cupertino,  California  95014, a written notice or revocation or a duly executed
proxy  bearing a later date,  or it may be revoked by attending  the meeting and
voting in person.

SOLICITATION

     The cost of  soliciting  proxies in the enclosed  form will be borne by the
Company.  Solicitation  will be made primarily by mail but  shareholders  may be
solicited by telephone,  telegraph,  or personal contact. The board of directors
may retain the services of a  proxy-soliciting  firm for soliciting proxies from
those entities holding shares in street name.

VOTES REQUIRED

     The affirmative vote of the holders of a majority of the outstanding shares
of the  Common  Stock,  either  voting in person or by proxy,  is  necessary  to
approve Proposal 6, the Reincorporation  Merger. The remaining proposals require
only approval of the shareholders, which is defined under California law to mean
the affirmative  vote of a majority of the shares  represented and voting at the
Special Meeting.

   
     Section 310(a) of the CGCL provides that a contract or transaction  between
a director or directors of the corporation and the  corporation,  or between the
corporation  and  another  organization  in which the  director  has a  material
financial  interest,  is not void or voidable  if (1) the facts  relating to the
interests  of  a  director  or  directors  are  fully   disclosed  or  known  to
shareholders  and the  contract or  agreement  is approved  or  identified  by a
majority of the  shareholders  with the shares owned by the interested  director
not being entitled to vote on the matter,  or (2) the facts are fully  disclosed
or known to the  board of  directors,  and the  board of  directors  authorizes,
approves or ratifies the contract or transaction in good faith without  counting
the vote of the interested director or directors and the contract or transaction
is just and  reasonable  as to the  corporation  at the  time it is  authorized,
approved  or  ratified.  The Berg  Acquisition,  which is subject to approval or
ratification  pursuant to Proposals 2, 3 4 and 5 involves  contracts between the
Company and Carl E. Berg,  members of his Immediate  Family and his  Affiliates.
Shareholder approval of the Reincorporation  Merger will include adoption of the
Charter and the Mission  West-Maryland  by laws which  include  provisions  that
benefit  Mr.  Berg,  members of his  Immediate  Family and his  Affiliates.  The
Company  believes that the approval by the  Company's  board of directors of the
Berg  Acquisition  and the  Reincorporation  Merger  in May 1998  satisfied  the
requirements of Section 310(a).  The Company also seeks ratification of the Berg
Acquisition and the  Reincorporation,  however,  by the holders of a majority of
the  outstanding  shares of Common Stock  exclusive of the 48,133 shares held in
the aggregate by members of the Berg Group.
    


CONSEQUENCES IF THE PROPOSALS ARE NOT APPROVED

   
     The board of directors  adopted  resolutions  approving  the  contracts and
transactions  comprising the Berg Acquisition and the Reincorporation  Merger on
May 14, 1998, subject to shareholder  approval or ratification,  as the case may
be. AMEX rules or the CGCL require  shareholder  approval only of Proposals 1, 5
and 6, but the board of directors has determined to seek shareholder approval of
all the UPREIT  Transactions due to the materiality of such transactions and the
potential  conflicts  of  interests  between  the  Company  and the Berg  Group.
Management and the board of directors of the Company believe that such contracts
and  transactions  are and have been  carried out in the best  interests  of the
Company.  As the  Company and other  parties to the  Acquisition  Agreement  did
complete the Partnership  Closing in July 1998, the failure of the  shareholders
to approve the transaction would not render it ineffective  between the parties.
Similarly,  the Company  already has entered  into  binding  agreements  to sell
6,495,058 shares of Common Stock in the Private Placement. Within two years from
the date of the Partnership  Closing the holders of a majority of the L.P. Units
in  each  Operating  Partnership  may  call  the  Demand  Notes  issued  at  the
Partnership  Closing  and upon  acquisition  of the  Fremont  Properties,  which
currently total  approximately  $33.9 million and which the Company will need to
finance by July 2000. If the  shareholders do not approve the Private  Placement
at the Special  Meeting,  the Company will seek to obtain the amount of funds to
be provided by the Private  Placement in the same or another  manner,  including
through borrowings under the Wells Fargo Line.

     The failure of the shareholders to approve  Proposals 3 and 4 would deprive
the  Company  of the right to  acquire  the  Pending  Development  Projects  and
developments  constructed on the Berg Land Holdings.  The Company  believes this
would materially  diminish its ability to increase  revenues and expand its real
estate holdings within the next two years.

     If the  shareholders do not approve  Proposal 5, the limited  partners will
not be able to exchange  L.P.  Units for Common Stock,  and the Company's  Total
Market  Capitalization would be much lower.  Additionally,  the Company would be
unable  to meet its  obligations  to the  sellers  under  the  Pending  Projects
Acquisition Agreement, and thus, unable to enter into that agreement.

     The Company  and all other  parties  are  obligated  under the terms of the
Acquisition  Agreement as amended to use their  ultimate  best efforts to obtain
shareholder approval of the UPREIT Transactions.  Therefore, if the shareholders
fail  to  ratify  the  Partnership   Closing   transactions   and/or  the  other
transactions  comprising the Berg Acquisition by failing to approve Proposals 2,
3 and 4, the Company  intends to call another special meeting of shareholders at
which the Company again would seek such ratification and approval.
    

     In any event,  the  Company's  management  does not intend to recommend the
dissolution and liquidation of the Company even though the shareholders  fail to
approve any or all of the Proposals.  Under the CGCL, however, the holders of at
least  one-half  of  the  Company's   voting  shares  could  vote  in  favor  of
dissolution,  or the holders of at least  one-third  of the voting  shares could
initiate an action in Superior Court for involuntary dissolution of the Company.

<PAGE>

   
     The Berg  Acquisition  and the Private  Placement may be  consummated  upon
shareholder  approval  irrespective  of whether  the  shareholders  approve  the
Reincorporation  Merger.  If the  shareholders  fail to  adopt  Proposal  6, the
Company  nevertheless  intends  to elect to  become a REIT in 1998,  but it will
remain  subject  to the  CGCL,  and will not have  adopted  the  Charter  or the
proposed   bylaws  of  Mission   West-Maryland.   The   Company's   articles  of
incorporation  and  bylaws  do not  contain  share  ownership  limits  and other
restrictions  contained  in the Charter or proposed  bylaws that are intended to
help maintain REIT qualification,  however.  Therefore the Company would face a
greater risk of ceasing to qualify as a REIT if the  shareholders do not approve
the Reincorporation  Merger.See "COMPARISON OF SHAREHOLDERS RIGHTS" and "FEDERAL

                      BACKGROUND OF THE UPREIT TRANSACTIONS

INTRODUCTION

   
     Following the sale of all of its  properties in the first half of 1997, the
Company  considered  several  strategic  alternatives and decided in May 1997 to
enter into a Stock  Purchase  Agreement for the sale of 200,000  shares of newly
issued Common Stock for $900,000, or $4.50 per share, to BBE and other investors
designated  by BBE.  At that time,  BBE and the  Company  contemplated  that the
Company would become a vehicle to acquire  office/R&D real estate,  or interests
in entities owning such real estate, from Carl E. Berg and his affiliates. Since
then, the Company has been engaged in raising capital through private placements
of Common Stock,  and Mr. Berg and his  affiliates  have been  reorganizing  the
Operating Partnerships' predecessors,  making arrangements to acquire additional
R&D Properties and refinancing indebtedness secured by some of the Properties to
obtain more favorable loan terms.

     Pursuant  to the  Acquisition  Agreement  signed in May 1998 and amended in
July 1998,  the Company  acquired  an  approximate  12.11%  interest as the sole
general   partner  in  each  of  the  Operating   Partnerships.   The  Operating
Partnerships  now own all of the Berg  Properties  and the Acquired  Properties,
representing a total of  approximately  4.34 million rentable square feet of R&D
Properties.  In  addition,  the Company has agreed to acquire the  approximately
1.02 million rentable square feet of Pending  Development  Projects,  after they
have been  constructed  and leased,  including an approximate 0.5 million square
foot  project  expected to be occupied  by  Microsoft.  The Berg Group owns L.P.
Units  representing   approximately   82.52%  and  non-Berg  Group  parties  own
approximately 5.37% of the interests in the Operating  Partnerships prior to the
acquisition of any Pending Development Projects by the Operating Partnerships.
    

     In November  1997, the Company  effected a 1-for-30  reverse stock split of
the Common Stock (the "Reverse  Split").  All share and per share figures stated
in this Proxy Statement/Prospectus give effect to the Reverse Split.

BACKGROUND

   
     THE COMPANY. Until recently, the Company was engaged in developing, owning,
operating, and selling income-producing commercial real estate. Since completing
its most  recent  development  projects in 1991,  the Company has been  involved
principally  in owning and operating  real estate  projects.  In January and May
1997,  the Company  completed the sale of its entire real estate  portfolio held
prior to the Company's purchase of a 12.11% general partnership  interest in the
Operating Partnerships.
    

     The Company was formed in 1969 as Palomar Mortgage Investors,  a California
business  trust.  It  operated  as a REIT,  investing  primarily  in  short  and
intermediate-term  construction  and  development  loans  secured by first trust
deeds on real property. In 1974, the Company terminated new loan activity except
to facilitate the sale of property acquired from borrowers  through  foreclosure
or by deed in lieu of  foreclosure  and,  in 1975,  changed  its name to Mission
Investment Trust. In 1979, the Company terminated its status as a REIT and began
to develop and market the properties it owned. In 1982, the Company incorporated
under its  present  name.  The Company has two wholly  owned  subsidiaries,  MIT
Realty,  Inc. and Mission West Executive Aircraft Center,  Inc.  ("MWEAC").  MIT
Realty, Inc. and MWEAC are both inactive.

     In July 1996, the Company entered into an agreement to sell all of its real
estate assets. That agreement was subsequently terminated and replaced, as was a
subsequent agreement. On December 6, 1996, the Company entered into an agreement
to sell all of its real  estate  assets to Spieker  Properties,  L.P.  for $50.5
million in cash. Upon completion of the sale of eight  properties and one parcel
of land, the Company  received  $47.5 million in cash,  from which it repaid all
debt  encumbering the properties and paid a majority of the related  transaction
and closing costs,  including $3 million in "break-up"  fees from the terminated
sales transactions.

     On February 4, 1997, the Company  declared a special  dividend of $9.00 per
share payable on February 27, 1997 to all  shareholders of record as of February
19,  1997.  After  the  sale  of  assets  and the  payment  of the  dividend  to
shareholders,  only  nominal  assets  remained  in the  Company.  The  board  of
directors and management  considered  available  strategic  alternatives for the
remaining  corporate entity.  Those  alternatives  included possible business or
asset acquisitions or combinations, a sale of the corporate entity, and outright
liquidation.

   
     On May 27, 1997, the Company entered into the Stock Purchase Agreement with
BBE,  which  transferred  most of its  share  purchase  rights  to  unaffiliated
accredited  investors as of August 4, 1997. All such  investors  signed a Voting
Rights  Agreement  requiring them to vote their shares as recommended by Carl E.
Berg on behalf of BBE. A special meeting of  shareholders  was on held August 5,
1997, at which the  shareholders of the Company  approved the  transaction.  The
transaction  was  completed on September 2, 1997, at which time all officers and
directors of the Company  resigned,  and BBE and the other investors  acquired a
79.6% controlling ownership position in the Company as a group.

     On October 20, 1997, the Company paid a further  distribution  of $3.30 per
share to  shareholders  of record as of August 28,  1997,  from  available  cash
including $900,000 received in the September 1997 transaction. No portion of the
distribution  was  paid on  shares  acquired  by BBE and  its  co-investors.  In
connection with that  distribution,  the AMEX halted trading of the Common Stock
at the opening of trading on October 20, 1997.

                                    -22-
<PAGE>

     To  increase  the price  per share of the  Common  Stock,  raise  funds and
increase assets and  shareholders'  equity, at a special meeting of shareholders
held on November 10, 1997, the  shareholders of the Company approved the Reverse
Split,  and the sale of 1,250,000  newly issued  shares of Common Stock at $4.50
per  share  in  a  private  placement  offering.   The  Company  completed  that
transaction as of November 12, 1997.  Certain  purchasers of Common Stock in the
November  transaction  also signed a Voting Rights  Agreement  requiring them to
vote their  shares as  recommended  by Carl E. Berg on behalf of BBE.  Including
such  purchasers,  holders of more than 60% of the outstanding  shares of Common
Stock were  subject to one of the Voting  Rights  Agreements.  Also in  November
1997, the Company changed its fiscal year to December 31.

     The August and November 1997 private placements and the Reverse Stock Split
were  intended to increase the  likelihood  of the  resumption  of AMEX trading.
However,  neither the Company nor the AMEX set a deadline for the  resumption of
trading,  nor did AMEX provided  guidance beyond declaring its desire that there
be a firm  commitment for the Company to acquire a controlling  general  partner
interest in the partnerships holding the Berg Properties and to raise additional
capital.  In  addition,  the  Company did not want  trading to resume  until (i)
audited  financial  statements were  available,  (ii) the Company had adequately
disclosed  the  contemplated  UPREIT  Transactions,  (iii)  the terms of all the
transactions  had been  settled,  and (iv) the  Registration  Statement had been
declared  effective  by  the  Commission,   or  it  became  apparent  that  such
declaration was imminent.

     In September  1998, BBE elected to relinquish the potential  voting control
of the Company  represented  by the Voting Rights  Agreements  and  unilaterally
terminated them with notice to affected  parties.  As a result,  neither Carl E.
Berg nor any other member of the Berg Group has any right to cause a majority of
the shares of Common Stock to be voted in favor of  proposals  desired by him or
others in the Berg Group, including Proposals 1 through 6.

     THE OPERATING  PARTNERSHIPS.  The Company has acquired  control of the four
Operating  Partnerships  by  becoming  the  sole  general  partner  in each  one
effective as of July 1, 1998 for financial  statement,  income tax and reporting
purposes by purchasing an approximate  12.11%  interest in each of the Operating
Partnerships through the issuance of Demand Notes of approximately $8.9 million,
$6.9 million, $18.3 million, and $1.1 million to MWP, MWP I, MWP II and MWP III,
respectively.  Interest on the Demand Notes is computed at the rate of 7.25% per
annum.  Payment  demands  under  each  Demand  Note may be made by action of the
holders of a majority of the outstanding L.P. Units in the Operating Partnership
only upon the earlier of the closing of the Private Placement, or two years from
the of issuance date of the Demand Note.  Mr. Berg and other members of the Berg
Group control such a majority in each Operating  Partnership  other than MWP III
and would be able to place the Company in default upon a timely  demand that the
Company cannot honor.  The Company believes that all of the Demand Notes will be
repaid within two years after their  original  issuance date. If the proceeds of
the Private  Placement and other funds of the Company are insufficient to retire
the Demand  Notes in full at the closing of the Private  Placement,  the Company
intends to borrow  funds  under the Wells Fargo Line to repay the balance of the
demand Notes.

     The Operating Partnerships hold R&D Properties with an aggregate book value
as of September 30, 1998, of $506 million (including accumulated depreciation of
$2.6  million),  subject  to total  debt of $220  million.  The total  amount of
collateralized indebtedness of the Operating Partnerships is $220 million.

     In  connection  with  the  Partnership  Closing,   each  of  the  Operating
Partnerships and their limited partners entered into an Agreement for Assumption
and Allocation of Liabilities, under which the Limited Partners agreed to assume
personal liability for a certain  percentage of recourse  indebtedness under the
Wells Fargo Line, in the event of payment default by the Operating Partnerships,
as well as other  indebtedness  of such  partnerships in order to preserve basis
for federal income tax purposes.  Effective  September 30, 1998, the Company and
the  Operating  Partnerships  become  parties  to the Wells  Fargo Line and some
Limited Partners have guaranteed similar amounts of indebtedness under that line
of credit.  In addition,  certain Limited  Partners have guaranteed a portion of
the Prudential  Secured Loan to preserve tax basis.  The  Acquisition  Agreement
provides that Limited  Partners are entitled to assume or guaranty  indebtedness
of the Operating Partnerships in such proportions as they request.

     The Operating  Partnerships  have been  maintained as separate  entities to
avoid unnecessary  transfers of real estate interests and maintain favorable tax
depreciation  methods  and  periods  for  the  benefit  of the  current  Limited
Partners.  At present,  the Company has no intention of merging or combining any
of the Operating Partnerships.  The Acquisition Agreement does provide, however,
that the Company may operate the four limited  partnerships for some purposes as
if they were a single  enterprise.  The Company may commingle the funds and cash
flow of the partnerships,  and, generally, will make them joint obligors for all
recourse  indebtedness of the Partnership and secure mortgage debt in proportion
to the Properties held by the respective partnerships. Operating cash flow shall
be  distributed  based upon the total  partnership  interests  in the  Operating
Partnerships,  and the Company's total share of distributions from the Operating
Partnerships will be equal to its overall  percentage  interest in the Operating
Partnerships from time to time. The Acquisition Agreement  contemplates that all
financing,  investing, property acquisitions and dispositions,  and all business
expansion  activities  of the Company  and the  Operating  Partnerships  will be
undertaken through the Operating Partnerships in a manner intended to maintain a
ratio of net equity value for each of the four limited partnerships to the total
net equity  value of the  Operating  Partnerships  as a whole that is similar to
such ratio as of the July 1, 1998 effective date of the Partnership Closing. See
"THE ACQUISITION AGREEMENT."

     The  Acquisition  Agreement  provides for  reallocations  of interests  and
adjustments in the amounts payable by the Company to each Operating  Partnership
in exchange for its general partnership  interest based upon differences between
the amount of debt encumbering the Properties of an Operating  Partnership as of
the  effective  date of the  Partnership  Closing and the amount of such debt on
May, 14, 1998. In conjunction  with the  Partnership  Closing and the Prudential
Secured Loan refinancing, final closing accounting entries and adjustments as of
June 30, 1998 were made on the books of the  predecessors  of the four Operating
Partnerships.  Due to higher than  estimated  closing debt  balances,  the total
number of L.P.  Units was reduced by 7,426,773  from  66,906,406  L.P.  Units to
59,479,633  L.P. Units to reflect the number of L.P. Units properly  outstanding
as of July 1, 1998,  computed  with  reference  to the agreed upon  valuation of
$4.50 per Outstanding Share and the net equity value of $267,658,348  determined
for the  predecessors of the Operating  Partnerships as of June 30, 1998. Due to
the  reduction in total L.P.  Units,  the Company's  recomputed  interest in the
Operating Partnerships increased automatically to 12.11%.

     The Operating  Partnerships  now have an aggregate of 59,479,633 L.P. Units
outstanding,  of which  55,845,938 L.P. Units are held by Carl E. Berg and other
members of the Berg Group. All of the Operating Partnerships are governed by the
terms of the Operating  Partnership  Agreement.  Upon the final closing date for
the Berg  Acquisition  and  shareholder  approval  at the Special  Meeting,  the
Operating  Partnerships also will be subject to the terms of the Exchange Rights
Agreement, the Pending Projects Acquisition Agreement and the Option Agreement.
    

     All  holders of L.P.  Units  (other  than Carl Berg and Clyde Berg) may put
their L.P. Units for redemption by the Operating Partnerships not more than once
each year,  subject to the  Company's  right to  purchase  such units with funds
raised  through an  offering  of new shares of Common  Stock,  and subject to an
aggregate annual  limitation of $1 million for the total purchase price,  unless
the Company otherwise elects.  Upon the exercise of such put rights,  the holder
of the L.P. Units will receive cash. In addition,  the holders of the L.P. Units
may  exchange  their  L.P.  Units  for  shares  of Common  Stock  under  certain
circumstances. See "OPERATING PARTNERSHIP AGREEMENT--Exchange Rights, Put Rights
and Registration Rights."

   
     THE PRIVATE PLACEMENT.  To partially finance its acquisition of the general
partner interests in the Operating Partnerships,  the Company has agreed to sell
6,495,058  shares of  Common  Stock at a price of $4.50 per share to a number of
accredited  investors  in  two  separate  private  placements.  In  one  of  the
transactions,  Ingalls & Snyder has acted as the placement agent for the sale of
5,800,000 shares of Common Stock for a total cash purchase price of $26,100,000.
Ingalls & Snyder is  entitled  to receive a  commission  of $0.05 per share from
each of the  purchasers  payable at the closing for the  purchase of the shares.
The  Company is not  obligated  to pay these  commissions.  The Ingalls & Snyder
private placement was offered through a Private Placement Memorandum dated as of
April 27, 1998 and was fully  subscribed on May 4, 1998.  At the same time,  the
Company  effected  an  additional  private  placement  for the offer and sale of
695,058 shares of Common Stock at a price of $4.50 per share to a separate group
of  investors,  including  Mr.  Berg and  consisting  primarily  of friends  and
relatives of the Company's senior management. In the transaction,  John Moran, a
principal of Ingalls & Snyder,  will receive  200,000  shares of Common Stock at
the closing in payment for services  rendered  related to the  Company's  recent
capital formation efforts in assisting the Company to obtain its financing.  The
other 495,058 shares will be sold for cash. The Private Placement is expected to
close  on the  final  closing  date  for the  Berg  Acquisition  but  only  upon
shareholder  approval  at the Special  Meeting.  All of the  purchasers  in both
transactions  have signed a stock purchase  agreement  which  constitutes  their
irrevocable  commitment to purchase the shares of Common Stock,  subject only to
customary   closing   conditions   such  as  the   accuracy  of  the   Company's
representations  and  warranties,  in  addition  to the  approval of the Private
Placement by the shareholders at the Special Meeting. All of the purchasers have
represented  to the  Company  that they are  accredited  investors.  The Company
believes that some of the  investors  who have agreed to purchase  shares in the
Private  Placement may fail to close because they will not have available  funds
that they  possessed  in May 1998,  may no longer view the purchase of shares of
Common Stock as a desirable investment,  or for some other reason, may refuse to
perform their  obligations under the stock purchase  agreement.  If this occurs,
the Company will seek to enforce those agreements, or, if management decides not
to sue  defaulting  investors,  the  Company  intends to replace  lost  purchase
proceeds by selling the authorized  shares of Common Stock to other investors at
$4.50 per share or other  available  price,  or by borrowing the funds under the
Wells Fargo Line.

     The  Commission  has advised the Company  that it does not believe that the
shares  of New  Common  Stock to be  issued  in the  Reincorporation  Merger  in
exchange for the shares of Common Stock purchased in the Private  Placement will
be subject to resale under Rule 145(d). Accordingly, although the Company has no
contractual  obligation to do so, the Company has  registered  such shares under
the Registration  Statement for reoffer and resale by the holders during periods
that the Registration  Statement remains effective under the Securities Act. The
Company  presently  intends to maintain the  effectiveness  of the  Registration
Statement, or a successor registration statement,  for this purpose for a period
of one year  after  the  closing  date  for the  Private  Placement,  but is not
obligated to do so.  Furthermore,  the Company has reserved the right to require
the selling  stockholders  to refrain from making  offers and sales  pursuant to
such  Registration  Statement for any period in which the Company has determined
that it would be  detrimental  to the  Company or its  stockholders  to continue
offering or selling shares under the Registration Statement.  Principally,  this
would  occur at  times  when the  Company  had  declined  to  disclose  material
nonpublic information. See "THE SELLING STOCKHOLDERS."

REASONS FOR THE PRIVATE PLACEMENT AND THE BERG ACQUISITION

     The board of directors  believes  that the Private  Placement  and the Berg
Acquisition  represent  effective means for rapidly  acquiring (i) a substantial
portfolio of Silicon  Valley R&D  Properties,  (ii) a strong and effective  real
estate  management  operation,  and  (iii) a  substantial  presence  in the REIT
industry for future  acquisitions  and raising  capital to finance the Company's
operations.  Except for the Excluded Properties, the Properties in the Company's
initial  portfolio include all of the Silicon Valley R&D Properties owned by any
of the Berg  Group  members  prior to the  Partnership  Closing.  Moreover,  the
acquisition of a controlling interest in the Operating  Partnerships rather than
the  direct  acquisition  of  any  of  the  Properties  enhances  the  Company's
acquisition and development  strategy by providing several  alternatives  (e.g.,
cash, Common Stock or L.P. Units) for acquiring the Pending Development Projects
and one or more of the Berg  Land  Holdings  from the  Berg  Group or  acquiring
additional  properties  from third  parties.  The  Company  believes  that these
alternative  currencies will enable it to acquire  desirable  buildings or sites
from  sellers  (including  the Berg  Group) who seek the  liquidity  provided by
shares of Common Stock,  or to offer L.P.  Units to sellers  (including the Berg
Group)  interested in deferring  potential  taxable gain.  Furthermore,  it will
allow the Company the  flexibility  to acquire  significant  properties  without
using cash or issuing  Common Stock to sellers  whose  ownership  thereof  would
cause them to exceed the Ownership Limit. By completing the Partnership  Closing
effective as of July 1, 1998 and in advance of the Special Meeting,  the Company
is able to consolidate the balance sheets and operating results of the Operating
Partnerships with its own financial statements for the entire second half of the
current  fiscal  year.  The  Company  believes  that  this  has  simplified  the
accounting procedures associated with recording the associated transactions, has
permitted clearer financial  statement  presentation,  reduced the risk that the
Company might fail to meet the 75% gross income test for REIT  qualification  in
1998, and will help the Company to avoid regulation under the Investment Company
Act of 1940.
    

SUMMARY OF THE TRANSACTIONS

   
     The  Berg  Acquisition  and  Private  Placement  transactions  include  the
following events:
    

- -    The Company will sell 6,495,058  shares of Common Stock for net proceeds of
     $28.3 million, including 200,000 shares of Common Stock valued at $4.50 per
     share to John Moran as consideration for consulting services related to the
     Company's recent capital formation efforts.

   
- -    The  former  general  partners  in each of the  four  limited  partnerships
     comprising the Operating  Partnerships  have resigned.  BBE and Kontrabecki
     have become limited partners in MWP and MWP III, respectively.  Berg & Berg
     Developers  LLC and Berg  Family  Partners  LLC were  owned by the  limited
     partners in MWP I and MWP II in identical  proportions to their  respective
     interests in such partnerships and were dissolved  simultaneously  with the
     Partnership Closing.

- -    The  Company  has  become  the  sole  general   partner  of  the  Operating
     Partnerships by acquiring an approximate 12.11% interest in the capital and
     profits of the Operating Partnerships for $35.2 million.

- -    Existing Limited Partnership  interests have been converted into 46,832,260
     L.P.  Units  and a total of  12,647,373  L.P.  Units  have  been  issued in
     exchange for R&D  Properties  contributed  to MWP by Carl E. Berg,  certain
     other Berg Group members, and two of the Kontrabecki Partnerships.
    

                                    -24-
<PAGE>

   
- -    The Limited  Partners  will obtain the right to exchange each of their L.P.
     Units for one share of Common Stock upon certain circumstances.

- -    Certain  Limited  Partners  have the right to put their  L.P.  Units to the
     Operating  Partnerships  once  each  year for cash at a price  equal to the
     10-day  average  trading price for the Common Stock,  and by agreement with
     the Company,  it will have the option to purchase  the  tendered  units for
     cash or shares of Common Stock at the same price. The total annual purchase
     price of the  tendered  L.P.  Units may not exceed $1 million  without  the
     Company's consent.
    

- -    Certain Berg Group  members have agreed with the Company that the Operating
     Partnerships will have the right to acquire each of the Pending Development
     Projects in exchange for a specified  number of L.P. Units (estimated to be
     a total of 33,919,072 L.P. Units) when each such Project has been completed
     and leased.  The number of L.P.  Units to be issued will be adjusted if the
     Property's  first-year monthly rental rate per square foot differs from the
     amount projected under the Pending Project Acquisition Agreement.

   
- -    The Berg Group will grant to the Company and the Operating Partnerships the
     right to purchase the Berg Land Holdings at a fixed formula pursuant to the
     Option  Agreement  as long as the Berg  Group  holds,  or has the  right to
     acquire,  shares  representing  65% of the Common Stock on a  Fully-Diluted
     basis.  In addition,  the Berg Group will provide  certain  rights of first
     offer to the Company and the Operating  Partnerships  in the event the Berg
     Group exercises any reserved rights to develop the Berg Land Holdings.

- -    Berg & Berg has transferred its property management business to the Company
     and has leased a portion of its Bandley Drive  headquarters  to the Company
     pursuant to the Office Lease.

     - For income tax reasons  certain Limited  Partners have assumed  secondary
personal  liability of some existing  debt,  and some of those Limited  Partners
have  guarantied  a portion of the  Prudential  Secured Loan and the Wells Fargo
Line. The liability assumption and allocation agreements and guaranties obligate
those  Limited  Partners to repay the debt to the extent the lender is unable to
receive payment through recourse to the Operating Partnerships and their assets.
    

CONSEQUENCES OF THE BERG ACQUISITION AND THE PRIVATE PLACEMENT

   
     The  Berg  Acquisition  and the  Private  Placement  have or will  have the
following consequences:
    

- -    The existing  shareholders of the Company will own approximately  20.73% of
     the outstanding  Common Stock of the Company,  and after this  transaction,
     the  purchasers  of  Common  Stock  in  the  Private   Placement  will  own
     approximately 79.27% of the outstanding voting securities of the Company.

   
- -    The Company is the sole general partner of, and owns an approximate  12.11%
     interest in, the Operating Partnerships.

- -    The  members of the Berg  Group  beneficially  own  55,845,938  L.P.  Units
     representing  in the aggregate an approximate  82.52%  limited  partnership
     interest in the Operating Partnerships.

- -    Individuals  and entities,  other than members of the Berg Group,  directly
     and indirectly own 3,633,695  L.P. Units  representing  in the aggregate an
     approximate   5.37%   limited   partnership   interest  in  the   Operating
     Partnerships.
    

- -    The  Operating Partnerships  will  own  the  fee  interest  in  all  of the
     Properties.

                                      -25-
<PAGE>

   
- -    The proceeds of the Prudential  Secured Loan along with the proceeds of the
     Company's  purchase of its interest in the Operating  Partnerships and cash
     on hand prior to the Partnership  Closing of the Berg Acquisition have been
     used to repay  existing  debt  secured by the  Properties,  including  debt
     effectively incurred prior to the effective date of the Partnership Closing
     to fund  substantially  all of a distribution  of $138.7 million to Carl E.
     Berg and Clyde J. Berg.
    

BENEFITS TO THE BERG GROUP

     The members of the Berg Group,  and to a lesser  extent the  non-affiliated
Limited  Partners in the Operating Partnerships,  will realize benefits from the
Berg Acquisition. These benefits include:

   
- -    All of the L.P. Units in the Operating  Partnerships  will be  exchangeable
     for  shares of Common  Stock  pursuant  to the  Exchange  Rights  Agreement
     (subject to the  Ownership  Limit).  L.P.  Units held by other than Carl E.
     Berg  and  Clyde J.  Berg may be  tendered  to the  Operating  Partnerships
     pursuant to the Put Rights. Under certain circumstances, the holders of the
     L.P.  Units also may require  the Company to register  the shares of Common
     Stock received upon  conversion of the L.P. Units.  Accordingly,  after the
     expiration  of certain  restrictions  upon the exercise of these  liquidity
     rights, the Berg Group's ownership  interest in the Operating  Partnerships
     will be more liquid than its ownership interest in the Berg Properties, and
     the  partnership  interests  beneficially  owned  by  the  partners  in the
     Operating  Partnerships  will be more liquid than their  current  ownership
     interests in each of the four limited  partnerships  that will comprise the
     Operating Partnerships.

- -    Carl E. Berg and  Clyde J.  Berg  received  distributions  totaling  $138.7
     million  from  MWP I and  MWP  II  prior  to  the  effective  date  of  the
     Partnership Closing.

- -    Certain debt relating to the Properties was refinanced, including debt owed
     under  the  Wells  Fargo  Line for  which  members  of the Berg  Group  are
     personally  liable.  However,  members of the Berg Group and other  Limited
     Partners in the Operating  Partnerships have provided  personal  guaranties
     with respect to all or some portion of the debt for income tax reasons.
    

- -    Carl E. Berg will receive an annual salary of  approximately  $100,000 plus
     additional  benefits as the Chief  Executive  Officer of the  Company.  See
     "MANAGEMENT--Executive Compensation."

VALUATION OF INTERESTS

   
     BERG  ACQUISITION.  Pursuant  to the  Berg  Acquisition,  the  Company  has
succeeded to the Silicon Valley R&D Property  ownership and management  business
of the Berg Group  through the  Company's  general  partnership  interest in the
Operating  Partnerships.  In October 1997, the board of directors of the Company
determined  that,  until  such  time  as  the  Company  had  acquired  operating
properties or other assets which would generate reportable income and funds from
operations,  all issuances of Common Stock and transactions involving the actual
or contingent  issuance of equity securities of the Company would be effected at
a price of $4.50 per share, or the equivalent  thereof.  The Company sold shares
of Common Stock at that price in a private  placement  in September  1997 and in
another  private  placement in November  1997.  The closing  price of the Common
Stock,  as quoted on the AMEX,  was $3.38 on October 17, 1997,  the last trading
date prior to the halt in trading  declared by the AMEX  effective as of October
20,  1997.  On October 21, 1997,  a special  distribution  of $3.30 per share of
Common  Stock was paid to  shareholders  of record as of August 28,  1997.  Upon
approval  of the  shareholders  and  filing  an  amendment  to the  articles  of
incorporation  of the Company on November 10, 1997, the Company effected Reverse
Split, which the board of directors expected to result in each outstanding share
of Common  Stock  having a value  approximately  equal to the $4.50  price which
investors had paid in the private placement transaction on November 12, 1997. In
May 1998, the Company agreed to sell shares of Common Stock to the purchasers in
the Private Placement at $4.50 per share. Pursuant to the Acquisition Agreement,
the Company agreed to acquire its approximately  12.11% general partner interest
in the Operating  Partnerships  for $35.2 million,  which  (assuming  67,673,227
Outstanding  Shares)  equates  to a price of  approximately  $4.30  per share of
Common  Stock.  The  Company  and the Berg  Group  have used a price of $4.50 to
determine  the  value of each  L.P.  Unit as well as the  number  of L.P.  Units
issuable in  connection  with the  Operating  Partnerships'  acquisition  of the
Pending Development  Projects.  See "DESCRIPTION OF THE PROPERTIES--The  Pending
Development  Projects."  The price of $4.50 per share  selected  by the board of
directors  may not be  representative  of the trading price of a share of Common
Stock, and it is likely that the Common Stock will trade at a different price.

     Independent appraisals were not obtained to determine the fair market value
of  the  Berg  Properties  for  purposes  of the  Berg  Acquisition.  The  total
historical  cost of the Berg Properties was  approximately  $178 million at June
30, 1998 immediately prior to the effective date of the Partnership Closing. The
Company  believes,  however,  that the most  appropriate  valuation  is one that
reflects the value of the Silicon  Valley R&D Property  ownership and management
business of the Operating Partnerships, taken as a whole.

(1)  In 1997,  the  Company  changed  its fiscal  year end from  November  30 to
     December 31. Thus, the first quarter of 1997 includes the month of December
     1996.

(2)  During the first fiscal quarter in 1997 (on February 27, 1997), the Company
     paid a $9.00 special dividend ($270 adjusted to give retroactive  effect to
     the 1 for 30 reverse stock split).

(3)  During the fourth fiscal quarter in 1997 (on October 21, 1997), the Company
     paid a $3.30 special dividend ($99 adjusted to give  retroactive  effect to
     the 1 for 30 reverse stock split).

   
     As of September 30, 1998,  the  approximate  number of holders of record of
the Company's common stock was approximately  360. The Company paid no dividends
during fiscal 1996.  The Company  declared and paid a special  dividend of $9.00
per share ($270 per share,  post-split) on February 27, 1997. A special dividend
of $3.30 per share was paid on October 21, 1997 ($99 per share, post-split).
    

     The  Company  intends to qualify as a REIT for tax  purposes  in the fiscal

     from debt  restructuring  and sales of property,  plus real estate  related
     depreciation and amortization (excluding amortization of deferred financing
     costs and depreciation of non-real estate assets) and after adjustments for
     unconsolidated partnerships and joint ventures. Management considers FFO an
     appropriate  measure of  performance  of an equity REIT because, along with
     cash flows from operating  activities,  financing  activities and investing
     activities,  it provides  investors with an  understanding of the Company's
     ability to incur and service debt and make capital expenditures. FFO should
     not be  considered  as an  alternative  for  net  income  as a  measure  of
     profitability  nor is it  comparable  to cash flows  provided by  operating
     activities  determined in accordance  with GAAP.  FFO is not  comparable to
     similarly  entitled  items  reported by other REITs that do not define them
     exactly as the Company defines FFO. See "Distribution Policy."

                          THE BUSINESS OF BERG & BERG

HISTORY OF BERG & BERG

     Carl E. Berg, the Company's  President and Chief Executive  Officer and the
controlling  member of the Berg Group,  has been engaged in the  development and
long-term  ownership  of Silicon  Valley real estate for more than 25 years.  In
1969, Mr. Berg foresaw the rising demand for efficient, multi-purpose facilities
for the rapidly growing  electronics  industry in the area of Santa Clara County
that has come to be known as "Silicon  Valley" (a term that now encompasses much
of the  southern  portion of the San  Francisco  Bay Area).  See "--The  Silicon
Valley  R&D  Property  Market".  He formed a general  partnership,  Sobrato-Berg
Properties,  with John Sobrato to focus on the  development  of R&D  Properties,
that is,  mixed-use  facilities  providing  space for offices,  development  and
research, light manufacturing and assembly.  Between 1969 and 1980, Sobrato-Berg
Properties  acquired and developed  approximately  45 R&D  Properties,  totaling
approximately  3.5 million  rentable  square  feet.  In 1980,  Messrs.  Berg and
Sobrato terminated their partnership and, as a result of the subsequent division
of its assets, 20 properties totaling  approximately 1.2 million rentable square
feet were  transferred to Berg Family  Partnership,  owned by Mr. Berg and other
members of the Berg Group.

     In 1980, Mr. Berg and his brother,  Clyde J. Berg, organized Berg & Berg to
continue the business of acquiring and developing R&D  Properties.  Between 1980
and 1983,  Berg & Berg  acquired and  developed 18  additional  R&D  Properties,
totaling approximately 1.4 million rentable square feet.

     In 1983,  Berg & Berg's  assessment of the Silicon Valley  commercial  real
estate  market  suggested a significant  decline in demand for rental  property,
particularly  in  the  R&D  Property  segment  of  the  market.  Based  on  this
assessment,  in 1983 Berg & Berg focused its  attention on enhancing  investment
returns from its existing  portfolio of properties and  constructing  facilities
for identified  tenants on a build-to-suit  basis.  From 1983 until 1995, Berg &
Berg was engaged primarily in build-to-suit  development activities on a limited
basis in selected  locations  where  experience  with its  portfolio  properties
indicated  that new  buildings  could be rented  at rates  adequate  to  justify
anticipated   development   costs  and  provide  an  acceptable  return  on  its
investment.

     In  late  1994,  Berg & Berg  perceived  a  change  in the  market  for R&D
Properties  in  Silicon  Valley  and in 1995  acquired  over 60 acres of land in
Milpitas,  Fremont and Mountain View, California and over 450,000 square feet of
R&D Properties with short-term leases at below-market rents. During the past two
years,  Berg & Berg has purchased  land or options on land totaling more than 55
acres in south San Jose.  In 1995 and 1996,  Berg & Berg began  construction  of
eight buildings  comprising over 700,000 square feet and was one of the two most
active developers leasing and building R&D Properties in Silicon Valley.

     Since 1972,  Mr. Berg also has been  actively  involved in venture  capital
investments in technology companies in the Silicon Valley.  Directly and through
various venture capital partnerships, he has made early-round equity investments
in more  than 100  technology  companies,  including  such  companies  as Amdahl
Corporation,  Sun  Microsystems,  Inc.,  Integrated Device  Technologies,  Inc.,
Valence Technology, Inc., Iwerks Entertainment, Inc., On-Command Video, Inc. and
Videonics,  Inc.  Mr.  Berg has served on the boards of  directors  of  numerous
technology  companies and currently serves on six such boards.  These activities
have helped Berg & Berg to develop a detailed  understanding  of the real estate
requirements of technology companies, to acquire valuable market information, to
increase its name  recognition  within the venture  capital and  entrepreneurial
communities, and to manifest its commitment to the growth and success of Silicon
Valley companies.  The Company believes that Mr. Berg's substantial knowledge of
and contacts in the information  technology industry have provided a significant
benefit to Berg & Berg in the operation of its commercial real estate  business,
and will continue to benefit the Company after the Berg Acquisition.

REGIONAL ECONOMIC PROFILE

     The San Francisco Bay Area comprises nine counties,  including Santa Clara,
Alameda, Contra Costa, Marin, Napa, San Francisco,  San Mateo, Solano and Sonoma
Counties,  covering approximately 7,200 square miles. The San Francisco Bay Area
is the second  largest  metropolitan  area in  California  with over 6.5 million
people, and the fourth largest  metropolitan area in the United States after New
York, Los Angeles, and Chicago.

     The economy of the San  Francisco Bay Area is one of the strongest and most
diverse  in  the  nation.  The  growth  of  the  computer,   biotechnology,  and
engineering  industries propels the region's economy forward as new technologies
draw  strength  from a  broad  base of  industries,  services,  venture  capital
financing, banking,  universities,  and research institutions. The San Francisco
Bay Area's long term  relationship with Pacific Rim countries has made it one of
the major gateways for Asia and Far East trade.  Moreover, the San Francisco Bay
Area has a reputation as one of the most desirable areas in the United States to
visit,  which has made tourism a major growth  industry.  The San  Francisco Bay
Area is a center of all  resources  necessary to create,  develop and expand new
businesses.

     Factors   contributing  to  the  region's  economic  strength  include  the
following:

     -    TECHNOLOGY  CENTER.  The  Silicon  Valley  economy  has  an  expansive
          employment   base   of   technology,    semiconductor,    electronics,
          telecommunications,   software,   and   computer   related   companies
          unsurpassed in the nation and the world. The Silicon Valley is host to
          over 4,000 technology companies employing in excess of 250,000 people.
          Santa Clara County ranks fourth in the State of California in terms of
          employment  and  population  and is  headquarters  to many Fortune 500
          companies,  including Applied Materials,  Inc., Apple Computer,  Inc.,
          Intel Corporation,  Sun Microsystems,  U.S. Robotics,  Inc.,  National
          Semiconductor Corporation, Cisco Systems, Inc., and Hewlett-Packard.

     -    FINANCIAL  SERVICES CENTER.  The San Francisco Bay Area is the home of
          the  nation's   highest   density  of  venture   capital  firms,   the
          headquarters  for Bank of  America,  Wells Fargo  Bank,  and  numerous
          investment  banking  firms  specializing  in  technology   industries.
          According to the Price Waterhouse LLP National Venture Capital Survey,
          during  1997,  venture  capital  firms  invested  approximately  $3.66
          billion in Silicon Valley companies.

     -    TRANSPORTATION AND FREEWAYS.  Silicon Valley has an elaborate regional
          freeway system,  the San Jose International  Airport,  close access to
          the San  Francisco  International  Airport,  and a modern  light  rail
          system  that is  expected  to  cover  major  portions  of the  Silicon
          Valley's  R&D  areas  by  the  year  2000.   The  major  freeways  are
          Interstates  280, 680, and 880, U.S. 101, and Highway 85. U.S. 101 and
          Interstate  280  converge  in San Jose and  connect to San  Francisco,
          while  Interstate  880  connects  the  Oakland  area.  Interstate  680
          provides access to the East Bay and Pleasanton areas. Highway 85 forms
          a semi-circle  around San Jose and connects the main residential areas
          to the heart of Silicon Valley.

     -    HIGHLY EDUCATED WORK FORCE. The San Francisco Bay Area has the highest
          percentage   of   college-educated   adults  in  the  nation  and  its
          pre-eminent educational institutions,  such as Stanford University and
          the University of California at Berkeley,  have played a major role in
          making it one of the world's leading technology centers.  The presence
          of these major  research  institutions  and the highly  educated  work
          force has  fueled the  region's  economic  engine and will  enable the
          region to build on its strong technology base in the future.

     -    CENTER  FOR  INTERNATIONAL  TRADE.  The  San  Francisco  Bay  Area  is
          currently the fourth  largest trade district  behind Los Angeles,  New
          York and Detroit serving primarily the Pacific Rim countries.

THE SILICON VALLEY R&D PROPERTY MARKET

     Santa Clara County,  which  incorporates much of Silicon Valley,  including
the San Jose metropolitan  area, has grown in population from 659,000 in 1960 to
1,653,100  on  January 1,  1997,  according  to census  data.  San Jose,  with a
population of more than 850,000, is the third largest city in California and the
eleventh largest in the United States.  Santa Clara County is the largest county
in the San Francisco Bay Area  encompassing  an area of 1,312 square miles,  and
includes many communities of diverse size and nature.

     Much of  Santa  Clara  County's  economic  growth  has been  driven  by the
development and expansion of high technology industries.  In recent years, space
requirements  and higher rents for R&D Properties in Santa Clara County have led
technology  companies to seek  facilities  elsewhere at office parks  located in
southwestern  Alameda County and southwestern San Mateo County. As a result, the
Company  believes that the term "Silicon  Valley" now refers to the more or less
contiguous  areas  of  industrial  development  in all  three  counties  where a
substantial number of technology companies can be found.

     Supported by major  educational and research  institutions  and by a strong
venture  capital  community,   Silicon  Valley  has  been  instrumental  in  the
development and  commercialization of technology in virtually every major field.
Over the past 40 years the  Silicon  Valley  economy  has grown and  diversified
through an evolutionary process as successive  generations of technology emerge,
mature and are eventually replaced. In recent years, the continuous emergence of
new  generations of technology  companies has kept  unemployment  rates in Santa
Clara County  consistently  lower than California  rates overall,  and generally
lower than national rates, as shown by the following table:

     1997 unemployment  rates for the area referred to as Silicon Valley in this
     Proxy Statement/Prospectus are lower than the rates for Santa Clara County.

   
     While Silicon Valley  companies  often  establish  manufacturing  plants in
other  locations  where they can benefit from lower  facilities and labor costs,
the headquarters,  marketing and research and development  functions  associated
with running the company and  developing  new  products  often remain in Silicon
Valley.   This  occurs  because  of  the  availability  of  a  well-trained  and
experienced   workforce,   an   established   infrastructure   of  vendors   and
service-providers  and the proximity to major  universities  engaged in advanced
science and technology research.  Consequently,  the principal space requirement
for  entrepreneurial   technology   companies  in  Silicon  Valley  is  for  R&D
Properties. According to regular quarterly reports on R&D Properties prepared by
BT  Commercial  Real Estate ("BT  Commercial"),  Silicon  Valley R&D  Properties
currently  represent over 120 million rentable square feet, more than 50% of all
commercial  industrial space in Silicon Valley. At the end of the fourth quarter
of 1997, the vacancy rate for Silicon  Valley R&D  Properties  stood at 4.5%, an
approximate  10%  decrease  from the  fourth  quarter  of 1996.  Currently,  the
occupancy  rate  is  approximately  95% for  properties  in  good  condition  at
desirable locations.

(1)  Millions of square feet.

(2) Per square foot per month.

     As  indicated  by the table,  since 1995,  the Silicon  Valley R&D Property
market has seen a significant  reduction in the excess of gross  absorption over
net  absorption,  while  witnessing  declining  vacancy rates and  significantly
increasing rental rates. The Company does not anticipate a significant  increase
in gross  absorption  in this  market  because  there  are few  large  blocks of
contiguous  space and suitable  development  sites.  For example,  in the fourth
quarter of 1997,  only five blocks of contiguous  R&D Property space of at least
100,000  square  feet were  available  in the  entire  market,  according  to BT
Commercial.

   
     The Company  believes  that  average  asking  rental rates during 1998 will
exceed 1997 average asking rental rates and will remain level in 1999. According
to BT  Commercial,  between the fourth quarter of 1996 and the fourth quarter of
1997, average asking rental rates in the Silicon Valley R&D Property market rose
from  $1.11 to $1.39  per  square  foot per  month.  On the other  hand,  tenant
improvement allowances offered by landlords have declined substantially,  and in
desirable locations, like Cupertino, Mountain View, Sunnyvale, San Jose, Fremont
and  Milpitas,  now can be as much as 50%  lower  than they were in the past few
years.  Since January 1995,  over 1.4 million  rentable  square feet of the Berg
Properties  have been  leased to  approximately  45 tenants  with rents at least
equal to the average  asking  rental rate in the Silicon  Valley R&D  Properties
market.

BERG & BERG BUSINESS STRATEGY

     Berg & Berg's development  business and its portfolio of Silicon Valley R&D
Properties have been built on a business  strategy  incorporating  the following
elements:

          -    STRONG GEOGRAPHIC AND INDUSTRY FOCUS. Berg & Berg has focused its
               activities   on   addressing   the   facility   requirements   of
               technology-oriented  companies in the Silicon Valley. The Company
               believes  that  this  focus  has  enabled  Berg & Berg  to gain a
               thorough  understanding of the Silicon Valley real estate market,
               to anticipate  trends in the market,  to identify and concentrate
               its  efforts on the most  favorably  located  sub-regions  of the
               market and to take  advantage of its experience and its extensive
               contacts and relationships with local government  agencies,  real
               estate  brokers and  subcontractors,  as well as with tenants and
               prospective tenants.

          -    LEAN, EXPERIENCED MANAGEMENT TEAM. In part because of its primary
               focus on Silicon Valley and the special real estate  requirements
               of technology  tenants,  Berg & Berg has been able to conduct and
               expand its business  with a small  management  team  comprised of
               highly-qualified and experienced  professionals  working within a
               relatively flat organizational structure.  These managers share a
               common  approach  to property  development  and  management.  The
               Company believes that the leanness,  experience and continuity of
               this  management  team have enabled Berg & Berg to rapidly assess
               and respond to market  opportunities  and tenant needs,  minimize
               development and construction  risks,  control operating  expenses
               and  develop  and  maintain  excellent   relationships  with  its
               tenants.  The  Company  further  believes  that these  advantages
               translate  into  significantly  lower  costs for  operations  and
               construction  which  give the  Company  the  ability  to  compete
               favorably with other R&D Property  developers in Silicon  Valley,
               especially  for  build-to-suit  projects  subject to  competitive
               bidding.  Furthermore,  its lower cost structure should allow the
               Company to generate  better returns from  properties  whose value
               can be increased  through  appropriate  remodeling  and efficient
               property management.

          -    MARKET  AWARENESS AND  SENSITIVITY.  Berg & Berg has consistently
               followed a demand-driven approach to the R&D Property business in
               which it has used its in-depth  experience and extensive industry
               contacts to identify  the  facility  requirements  of tenants and
               potential   tenants  in  the  Silicon   Valley  and  its  various
               sub-regions.

          -    EMPHASIS ON GENERAL  PURPOSE  FACILITIES,  SINGLE TENANT PROJECTS
               AND LONG-TERM  TENANT  RELATIONSHIPS.  Most of the Properties are
               general purpose R&D Properties,  located in desirable sub-regions
               of the Silicon  Valley.  Such Properties have been developed for,
               or  leased   to,   single-tenants,   many  of  whom  are   large,
               publicly-traded  electronics  companies.  Most  of the  Company's
               major  tenants  have  occupied  their  Properties  for many years
               pursuant  to fully net leases  under  which the  tenant  pays all
               operating costs. The Company believes that Berg & Berg's practice
               of emphasizing the development of

                                      -34-

               single-tenant rather than multi-tenant properties has contributed
               to its relatively low turnover and high occupancy  rates and that
               the relatively  small number of tenants  occupying the Properties
               allows it to  efficiently  manage  the  Properties  and serve the
               needs of its tenants  without the need for an extensive  in-house
               staff or the assistance of a third-party management organization.
               In  addition,  this  emphasis  allows the Company to pay less for
               tenant  improvements and leasing  commissions than  multi-tenant,
               high  turnover  property  owners,  and also  reduces the time and
               expense  associated  with  obtaining  building  permits and other
               government  approvals.  The Company  believes that the relatively
               stable,  extended  relationships  which Berg & Berg has developed
               with its key tenants have been a valuable factor in the expansion
               of its business.

          -    SOUND PROPERTY MANAGEMENT PRACTICES.  Berg & Berg makes extensive
               use  of  its  experienced  in-house  architectural,   design  and
               construction   management   personnel   in  all   phases  of  its
               acquisition,  development and property management businesses, and
               focuses  on  similar  types  of  development   projects  to  more
               effectively  utilize  these  skills  and  experience.   For  each
               property,  the Berg & Berg staff develops a specific development,
               marketing and property management program. It selects vendors and
               subcontractors on a competitive bidding basis from a select group
               of  highly  qualified  firms  with  whom  it  maintains   ongoing
               relationships  and carefully  supervises  their work. The Company
               believes  that, as a result of these sound  operating  practices,
               Berg & Berg has acquired a reputation for completing its projects
               on time and within budget.

(1) Average monthly rental revenue per square foot has been determined by taking
    the base rent for the period, divided by the number of months in the period,
    and then divided by the total square feet of occupied space.

   
(2)  As defined by the National  Association  of Real Estate  Investment  Trusts
     ("NAREIT"),  FFO represents net income (loss) before  minority  interest of
     unitholders (computed in accordance with GAAP), excluding gains (or losses)
     from debt  restructuring  and sales of property,  plus real estate  related
     depreciation and amortization (excluding amortization of deferred financing
     costs and depreciation of non-real estate assets) and after adjustments for
     unconsolidated partnerships and joint ventures. Management considers FFO an
     appropriate  measure of  performance  of an equity REIT because, along with
     cash flows from operating  activities,  financing  activities and investing
     activities,  it provides  investors with an  understanding of the Company's
     ability to incur and service debt and make capital expenditures. FFO should
     not be  considered  as an  alternative  for  net  income  as a  measure  of
     profitability  nor is it  comparable  to cash flows  provided by  operating
     activities  determined in accordance  with GAAP.  FFO is not  comparable to
     similarly  entitled  items  reported by other REITs that do not define them
     exactly as the Company defines FFO. See "Distribution Policy."
    

(3) Non-cash  adjustments to FFO were as follows:  in all periods,  depreciation
    and  amortization;  in 1996, 1995 and 1993, gains on extinguishment of debt;
    and in 1995, gain on sale of property.

                          OPERATION FOR THE PROPERTIES

   
     The following  discussion  should be read in conjunction  with the Selected
Financial  Data and the Combined  Financial  Statements  for the  Properties and
notes  thereto  appearing  elsewhere  in this  Proxy  Statement/Prospectus.  The
Combined  Financial  Statements  of the Berg  Properties  are  comprised  of the

general partner and the beneficial owner of an approximately  12.11% interest in
the Operating  Partnerships with control of the operations and activities of the
Operating Partnerships and all of the Properties from July 1, 1998.
    

OVERVIEW

   
     The Berg  Properties  are a combination  of Silicon  Valley R&D  Properties
controlled  historically  by the Berg Group.  Since the  beginning of 1995,  the
aggregate R&D Property  square footage  represented  by the Berg  Properties has
increased  significantly  from approximately 2.9 million square feet at December
31, 1994 to  approximately  3.8 million square feet at June 30, 1998,  primarily
from the development of new buildings. Such increase combined with a substantial
increase in the overall  occupancy rate of the Berg Properties have  contributed
to a dramatic  increase in the  revenues  earned by the Berg Group from the Berg
Properties.
    

     The table below details the size of the Berg  Properties  portfolio and the
total occupancy rate as of each of the dates presented:

     Historically, entities within the Berg Group have developed and managed the
Berg Properties,  drawing on funds provided by operations,  lines of credit from
Wells Fargo (including the Wells Fargo Line),  direct property loans provided by
other lending  institutions,  and  contributions of capital from time to time by
members of the Berg Group,  principally to repay indebtedness  outstanding under
the Wells Fargo lines of credit.  In addition,  certain  affiliates  of the Berg
Group have used the Wells Fargo  lines of credit for other  ventures on a demand
basis,   including   loans  used  primarily  to  finance  the   construction  of
improvements  on  certain  of the Berg  Properties.  Those  loans  and all other
lending  arrangements with affiliates will be terminated upon the closing of the
Berg Acquisition.
    

     The table below  details the  borrowings  and  repayments by the Berg Group
during the periods indicated:

     Most of the Berg  Properties were developed by members of the Berg Group or
their Affiliates who have held such Properties  continuously since their initial
construction.  Occasionally,  the Berg  Group has  acquired  and sold  developed
properties,  as  well.  In 1995,  the Berg  Group  sold two  buildings  totaling
approximately  315,000  rentable  square feet: one building was sold directly to
the tenant,  Xilinx  Corporation;  the other building was  distributed by Berg &
Berg   Developers   to  its  partners  and  then  sold  to  Xilinx   Corporation
(collectively,  the "Xilinx Sales").  Immediately after the Xilinx Sales, Berg &
Berg  acquired  McCandless  Technology  Park  in  Milpitas,   California,  which
comprised  approximately 345,000 rentable square feet. Later in 1995, members of
the  Berg  Group  acquired  several  additional  R&D  Properties  consisting  of
approximately 110,000 rentable square feet.

     The table below summarizes dispositions,  new development, and acquisitions
of R&D  Properties by the Berg Group since  January 1, 1995, in rentable  square
footage:

     Since 1991, BBE has operated as a management  company providing services to
the Berg Group members and their Affiliates owning the Berg Properties, who have
paid BBE a  management  fee of  approximately  3% of gross base  rental  revenue
determined  on a cash  basis.  All  management  fee  arrangements  with BBE were
terminated as of July 1, 1998.
    

     Beginning in 1995, new leases  established for approximately 44 of the Berg
Properties  (including leases acquired in the purchase of McCandless  Technology
Park)  obligated  the  tenants  to pay  approximately  3% of the  base  rent  as
additional  monthly  common area  charges.  Berg & Berg views these charges as a
means for tenants to fund their liability for future repairs of a non-structural
nature ratably over the term of the lease. In the Combined Financial  Statements
of the Berg Properties these payments have been characterized as rent under GAAP
accounting, and no reserve has been established for any future repairs.

   
     As of July 1, 1998, the Company acquired its general  partnership  interest
in the Operating  Partnerships at the Partnership Closing. The Company's results
of operations,  cash flows, and liquidity  therefore include the Berg Properties
and the Acquired Properties from July 1, 1998.
    

RESULTS OF OPERATIONS

   
SIX MONTHS ENDED JUNE 30, 1998 COMPARED TO THE SIX MONTHS ENDED JUNE 30, 1997

      THE BERG PROPERTIES

     RENTAL REVENUES AND TENANT REIMBURSEMENTS. Rental revenue increased by $3.1
million  or 16.4%,  to $22.0  million  for the six months  ended  June 30,  1998
compared to $18.9  million for the six months ended June 30,  1997.  The primary
reasons for the  increase in rental  revenues  were the  increase in the overall
occupancy rate for the Berg  Properties,  from 96.9% at June 30, 1997 to 100% at
June 30, 1998, the addition of  approximately  187,000  rentable  square feet of
leased space during the third quarter of 1997 and higher rents  associated  with
new leases and  renewals.  Tenant  reimbursements  increased  by $0.9 million or
29.0%,  to $4.0  million  for the six months  ended June 30, 1998 as compared to
$3.1  million for the six months  ended June 30,  1997.  The  increase in tenant
reimbursements  was due primarily to the higher occupancy level and the increase
in total rentable square feet of leased space.

     EXPENSES. Total expenses for the Berg Properties increased by $0.3 million,
or 2.6%,  to $11.8  million for the six months  ended June 30, 1998  compared to
$11.5  million  for the six  months  ended  June 30,  1997.  Property  operating
expenses were $2.1 million for the six months ended June 30, 1998 and 1997. Real
estate taxes were $2.1  million for the six months ended June 30, 1998  compared
to $2.0 million for the six months ended June 30, 1997. Management fees (related
party)  increased  by $0.1  million,  or 20%, to $0.6 million for the six months
ended June 30, 1998 in  comparison to $0.5 million for the six months ended June
30, 1997. The increase in management  fees is a direct result of the increase in
rental revenues.  Interest  expense,  including  amounts owed to related parties
decreased by $0.4  million,  or 11.4%,  to $3.1 million for the six months ended
June 30, 1998  compared to $3.5  million for the six months ended June 30, 1997.
The decrease in interest  expense  resulted from a decrease in debt balances due
to normal recurring principal payments, as well as the repayment of $2.0 million
of related party debt.  Depreciation and amortization  expense increased by $0.5
million,  or 14.7%,  to $3.9  million for the six months  ended June 30, 1998 as
compared to $3.4 million for the six months ended June 30, 1997. The increase in
depreciation and amortization  expense resulted  primarily from new improvements
and new construction since the June 30, 1997.
    

                                     -39-
<PAGE>

   
     NET INCOME.  Net income  increased by  approximately  $3.7 million to $14.2
million for the six months  ended June 30,  1998,  an increase of 35.2% over the
net  income  of $10.5  million  for the six  months  ended  June 30,  1997.  The
substantial  rise in net  income  resulted  primarily  from  the  generation  of
additional revenues from new leases at higher rental rates and from the addition
of  approximately  187,000 rental square feet of leased space,  while  incurring
minimal increases in expenses.

      THE ACQUIRED PROPERTIES

     RENTAL  REVENUES  AND TENANT  REIMBURSEMENTS.  Rental  revenue  for the six
months ended June 30, 1998 was $3.3 million for the  Acquired  Properties,  with
$2.3 million coming from the Kontrabecki Properties and $1.0 million coming from
the Fremont Properties.  Tenant  reimbursements and other income were a combined
$0.2 million.

     EXPENSES. Total expenses for the Acquired Properties were $0.2 million, all
of which were attributable to the Fremont Properties. The Kontrabecki Properties
have  minimal  expenses  and tenant  reimbursements  as the tenants paid most of
their expenses directly to the service providers.

     REVENUE IN EXCESS OF CERTAIN  EXPENSES.  The combined  revenue in excess of
certain  expenses of the Acquired  Properties  was $3.3  million,  of which $2.3
million was derived from the  Kontrabecki  Properties  and $1.0 million from the
Fremont Properties.
    

YEAR ENDED DECEMBER 31, 1997 COMPARED TO YEAR ENDED DECEMBER 31, 1996

     THE BERG PROPERTIES

     RENTAL  REVENUES AND TENANT  REIMBURSEMENTS.  Rental  revenue  increased by
$11.3 million,  or 39.1%,  to $40.2 million for the year ended December 31, 1997
compared to $28.9  million for the year ended  December 31, 1996.  The principal
reasons for the  increase  in rental  revenue  were the  increase in the overall
occupancy rate for the Berg Properties, from 91.9% at December 31, 1996 to 97.7%
at December 31, 1997, the addition of approximately 388,000 rentable square feet
of leased space,  and scheduled  rental rate  increases.  Tenant  reimbursements
increased by $2.6 million, or approximately  66.7%, to $6.5 million for the year
ended  December 31, 1997 from $3.9 million for the year ended December 31, 1996.
The increase in tenant  reimbursements was due primarily to the higher occupancy
level,  an increase of 388,000  rentable  square  feet of leased  space,  and an
increase in the number of tenants  reimbursing the Berg Properties for operating
expenses rather than paying them directly to the service provider.

     EXPENSES. Total expenses for the Berg Properties increased by approximately
$3.3 million,  or 16.8%,  to $22.9 million for the year ended December 31, 1997,
compared  to $19.6  million  for the year  ended  December  31,  1996.  Property
operating expenses increased by $1.8 million,  or 94.7%, to $3.7 million for the
year ended  December 31, 1997 from $1.9 million for the year ended  December 31,
1996.  The  increase  in  operating  expenses  was offset by an increase of $2.6
million  in  tenant  reimbursements  and  was  due  primarily  to the  increased
occupancy of the Berg Properties and the  substantial  increase in leased square
footage.  Depreciation  expense  increased by $1.0  million,  or 14.9%,  to $7.7
million for the year ended December 31, 1997 as compared to $6.7 million for the
year ended  December 31, 1996.  The increase in  depreciation  expense  resulted
primarily  from  new  improvements  and  new  construction.  Real  estate  taxes
increased slightly by $0.4 million, or approximately  10.5%, to $4.2 million for
the year ended  December 31, 1997 from $3.8 million for the year ended  December
31, 1996.  Interest expense  (including amounts associated with related parties)
for the year ended December 31, 1997 was virtually unchanged from the year ended
December 31, 1996,  as debt  principal  balances  and  interest  rates  remained
substantially the same.

                                    -40-
<PAGE>

     NET INCOME. Income before extraordinary item increased by $10.6 million, or
approximately 80.3%, to $23.8 million for the year ended December 31, 1997, from
$ 13.2 million for the year ended December 31, 1996, as rental revenue increased
substantially  due to  increased  occupancy  of the Berg  Properties,  scheduled
rental rate  increases,  and the addition of leased  space  without a comparable
increase in total  expenses.  For the year ended  December 31, 1996,  net income
included an  extraordinary  gain of $0.6 million  related to the  forgiveness of
debt by Great West Life & Annuity Insurance Company.

     THE ACQUIRED PROPERTIES

     RENTAL  REVENUES  AND TENANT  REIMBURSEMENTS.  Rental  revenue for the year
ended December 31, 1997 was $5.4 million for the Acquired Properties,  with $4.1
million coming from the Kontrabecki  Properties and $1.3 million coming from the
Fremont  Properties,  which were  completed  during  the first  quarter of 1997.
Tenant  reimbursements and other income were a combined $0.3 million,  with $0.1
million attributable to the Kontrabecki Properties and $0.2 million attributable
to the Fremont Properties.

     EXPENSES. Total expenses for the Acquired Properties were $0.29 million, of
which $0.02  million  applied to the  Kontrabecki  Properties  and $0.27 million
applied to the Fremont Properties.

     REVENUE IN EXCESS OF CERTAIN  EXPENSES.  The combined  revenue in excess of
certain  expenses of the Acquired  Properties  was $5.4  million,  of which $4.2
million were  generated by the  Kontrabecki  Properties  and $1.2 million by the
Fremont Properties.

YEAR ENDED DECEMBER 31, 1996 COMPARED TO YEAR ENDED DECEMBER 31, 1995

     The Berg Properties

     RENTAL REVENUE AND TENANT REIMBURSEMENTS.  Rental revenue increased by $5.8
million,  or 25.1%,  to $28.9 million for the year ended  December 31, 1996 from
$23.1  million for the year ended  December 31, 1995,  as the overall  occupancy
rate increased to 91.9% at December 31, 1996 from 87.4% at December 31, 1995. In
addition, rental rates rose for new and renewal leases, and the Berg Group added
approximately  196,000  square  feet of new  leased R&D  Properties  to the Berg
Properties.  Tenant  reimbursements  decreased by $0.3 million, or 7.1%, to $3.9
million  for the year ended  December  31,  1996 from $4.2  million for the year
ended December 31, 1995, as the additional tenant reimbursements attributable to
increased  occupancy of the Berg  Properties  and the  acquisition of additional
leased space were more than offset by the decline in tenant  reimbursements as a
result  of new  tenants  paying  operating  expenses  directly  to  the  service
providers.

     EXPENSES.  Total  expenses  increased by 2.1% to $19.6 million for the year
ended  December 31,  1996,  from $19.2  million for the year ended  December 31,
1995.  Operating  expenses  decreased by $0.1 million,  or 5%. Interest  expense
decreased by $0.2 million,  or 3.0% to $6.4 million for the year ended  December
31,  1996  from  $6.6  million  for the  year  ended  December  31,  1995 due to
construction  activities and related  borrowings.  Depreciation and amortization
expense increased by $0.4 million, or 6.3% for the year ended December 31, 1996,
to $6.7 million from $6.3 million for the year ended  December 31, 1995,  due to
the addition of new R&D  Properties  and leased space acquired by the Berg Group
during 1995 and 1996.  Real estate taxes  increased by $0.2 million,  or 5.6% to
$3.8 million for the year ended December 31, 1996 from $3.6 million for the year
ended  December 31, 1995, as a result of minor  reassessments  as values rose on
certain Berg Properties while the real estate tax increases  attributable to the
increase in net rentable  square  footage were offset by the  disposition of two
R&D  Properties  in the Xilinx  Sales.  For the year ended  December  31,  1996,
general and administrative  expenses, as reflected by the management fee paid to
BBE, increased with rental revenues.

     NET INCOME.  Income  before  gain on sale of real estate and  extraordinary
items increased by $5.1 million to $13.2 million for the year ended December 31,
1996,  from $8.1  million for the year ended  December  31,  1995,  as growth in
revenues far exceeded the increase in expenses.  Income  decreased  for the year
ended December 31, 1996,  however,  due to the effect of two extraordinary items
for the year ended  December  31,  1995:  The $20.8  million  gain on the Xilinx
Sales,  and a $3.2 million gain which  resulted from the  forgiveness of debt by
Great West Life & Annuity  Insurance  Company.  For the year ended  December 31,
1996, $0.6 million of extraordinary  gain also resulted from debt forgiveness by
the same lender.

                                    -41-
<PAGE>

     THE KONTRABECKI PROPERTIES

     RENTAL  REVENUE AND TENANT  REIMBURSEMENTS.  Rental  revenue  increased  by
approximately $0.3 million, or 9.7%, to $3.4 million for the year ended December
31, 1996 from $3.1 million for the year ended  December  31, 1995.  The increase
was primarily due to an increase in occupancy to 86.9% at December 31, 1996 from
81.8% at December 31, 1995, and rising rental rates for new and renewal  leases.
Tenant reimbursements and other income were level for the period.

     EXPENSES. Total expenses decreased substantially by 48.8%, to $0.22 million
for the year ended  December  31, 1996,  compared to $0.43  million for the year
ended  December 31, 1995.  For the year ended  December 31, 1996,  operating and
maintenance expenses decreased by $0.25 million, or 59.5%, to $0.17 million from
$0.42 million for the year ended December 31, 1995. These substantial reductions
resulted  primarily  from the  lease of  vacant  space to  tenants  who paid the
expenses directly to the service provider.

     REVENUE IN EXCESS OF CERTAIN EXPENSES.  The Kontrabecki Properties produced
revenue  in excess of  certain  expenses  of $3.23  million  for the year  ended
December 31, 1996, an approximately  16.8% increase over the same period for the
year ended December 31, 1995.

PRO FORMA LIQUIDITY AND CAPITAL RESOURCES

   
     The Company  expects its FFO to be the  principal  source of liquidity  for
distributions,   debt  service,   leasing   commissions  and  recurring  capital
expenditures.  The Company has not operated  previously as a REIT and has no FFO
operating  history.  The Company also has not previously paid regular  dividends
and other  distributions  to its shareholders and can make no assurances that it
will be able to do so in the future.  Based solely upon past  operating  results
for the  Properties  and the results of  operations  for the nine  months  ended
September 30, 1998, on a pro forma basis,  the Company  expects its FFO for 1998
to be  adequate  to meet  projected  distributions  to  shareholders  and  other
presently anticipated liquidity requirements in 1998. See "DISTRIBUTION POLICY."

     After closing the Private  Placement at the final closing date for the Berg
Acquisition,  the Company  expects to have total  indebtedness  remaining on the
Properties  on a pro forma basis of  approximately  $223  million,  comprised of
mortgage debt secured by certain of the Properties under the Prudential  Secured
Loan and existing  secured loan  arrangements  of $93  million.  The  Prudential
Secured Loan totals $130  million,  bearing an interest rate of 6.56% per annum,
maturing  October 15, 2008, and is payable in monthly  installments of principal
(based upon a 30 year  amortization) and interest of approximately $0.8 million.
The Company has paid total fees of approximately $0.9 million in connection with
this loan. The Company also has assumed  responsibility for a $100 million Wells
Fargo Line which had an outstanding  balance of approximately  $39 million as of
September  30,  1998.  Interest  rates on the Wells Fargo Line are  variable and
ranged from  approximately  7.0% to 8.20% over the past three fiscal years.  The
average rate for the three months ended September 30, 1998 was 7.25%.  The Wells
Fargo Line expires in October 1999 and will need to be replaced. There can be no
assurance  that the Company will be able to obtain a similar line of credit with
similar  terms  and  the  Company's  cost  of  borrowing  funds  could  increase
substantially. The Company's Debt to Total Market Capitalization ratio, assuming
no additional  draws on the Wells Fargo Line,  will be  approximately  42% based
upon an estimated Total Market Capitalization of approximately $525 million.

     The Company expects to meet its short-term liquidity requirements generally
through its initial working capital, the Wells Fargo Line, and net cash provided
by  operations.  The  Properties  require  periodic  investments  of capital for
tenant-related  capital expenditures and for general capital  improvements.  For
the years ended  December 31, 1993 through  December  31,  1997,  the  recurring
tenant  improvement costs and leasing  commissions  incurred with respect to new
leases and lease renewals of the Berg  Properties  averaged  approximately  $1.5
million annually.  Of the Acquired Properties,  only 83,902 square feet of space
is subject to leases that expire between  January 1, 1998 and December 31, 2001.
The Company will therefore have approximately 416,000 square feet under expiring
leases  annually  from  January 1, 1998 through  December 31, 2000.  The Company
expects  that the  average  annual cost of  recurring  tenant  improvements  and
leasing  commissions,  related to the  properties,  will be  approximately  $1.5
million from January 1, 1998  through  December 31, 2000.  It expects to recover
substantially  all of these  costs  from the  tenants  under the new or  renewed
leases  through  increases  in rental  rates.  The  Company  expects to meet its
long-term  liquidity  requirements  for the  funding  of  property  development,
property acquisitions and other material non-recurring capital improvements,  as
well as annual  tenders  of L.P.  Units by  certain  Limited  Partners,  through
long-term  secured and  unsecured  indebtedness  and the issuance of  additional
equity  securities  by the  Company.  See  "POLICIES  WITH  RESPECT  TO  CERTAIN
ACTIVITIES--Financing Policies."

HISTORICAL CASH FLOWS

     BERG PROPERTIES

   
     CASH  PROVIDED  FROM  OPERATIONS.  The  amount  of  net  cash  provided  by
operations has  consistently  increased  since 1995. The Berg Properties had net
cash provided by operating  activities of approximately  $17.4 million and $13.7
million  for the six months  ended  June 30,  1998 and 1997,  respectively,  and
approximately $29.9 million, $20.2 million and $16.4 million for the years ended
December 31, 1997, 1996 and 1995, respectively. The $3.7 million increase in net
cash  provided by  operating  activities  for the six months ended June 30, 1998
compared  to the same  period in 1997 was  primarily  due to an  increase in net
income.  The  approximately  $9.7  million  increase  in net  cash  provided  by
operating  activities  for the year ended  December 31, 1997 over the year ended
December  31, 1996 was  primarily  due to an  increase in net income,  partially
offset by an increase in other assets,  and deferred rent  receivable.  The $3.8
million increase in net cash provided by operating activities for the year ended
December 31, 1996 over the same period in 1995 was due  primarily to an increase
in income before gain on sale of real estate and extraordinary item.

     INVESTING ACTIVITIES. Net cash provided (used) in investing activities with
respect to the Berg Properties was approximately $0.7 million and $(9.9) million
for the six months ended June 30, 1998 and 1997, respectively, and approximately
$(17.3) million, $(29.3) million and $(6.4) million for the years ended December
31, 1997, 1996, and 1995,  respectively.  The $10.6 million increase in net cash
provided by investing activities for the six months ended June 30, 1998 compared
to the same  period in 1997 was  primarily  due to a  decrease  in  construction
activities. The approximately $12 million decrease in net cash used in investing
activities  for the year ended  December  31,  1997  compared  to the year ended
December  31,  1996 was  also  due to a  decrease  in  construction  activities.
Correspondingly,  the  approximately  $22.9 million increase in net cash used in
investing  activities  for the year ended December 31, 1996 compared to the year
ended  December 31, 1995, was primarily due to an increase in  construction  and
development  expenditures for a number of the R&D Properties,  including several
projects  in  McCandless  Technology  Park in  Milpitas.  The volume and cost of
construction and development activities for new projects and tenant improvements
in  connection  with new  leases  varies  from  year to year.  The  Company  has
estimated such  expenditures in connection with its estimation of pro forma cash
available for  distribution  during 1998,  and in determining  effective  annual
rents for the Berg  Properties.  There can be no assurance  that such  estimates
will reflect actual results,  however, and capital expenditures in prior periods
should not be viewed as indicative of expenditures in future periods.

     FINANCING ACTIVITIES. Net cash (used) provided in financing activities with
respect to the Berg Properties was $(23.8) million and $(0.005)  million for the
six months ended June 30, 1998 and 1997, respectively,  and $(8.4) million, $9.4
million,  and $(10.0)  million for the years ended  December 31, 1997,  1996 and
1995,  respectively.  Changes in financing  activities  generally  were directly
related to the level of new construction and development of R&D Properties.  For
the six months  ending  June 30,  1998,  total debt  increased  by $118,735 as a
result of the Company making  distributions to certain partners in the amount of
$142.5 million compared to an increase in total debt of $4.6 million for the six
months ended June 30, 1997.  Capital  distributions were $142.5 million and $5.0
million and capital  contributions  were nil and $0.4 million for the six months
ended June 30,  1998 and 1997,  respectively.  For the year ended  December  31,
1997,  the increase in total debt on the Berg  Properties  was $1.5 million less
than the  increase  in debt  during the same  period in 1996,  contributions  by
partners were reduced by $11.5 million,  and distributions to partners increased
by approximately $4.9 million. Comparing the year ended December 31, 1996 to the
year ended  December 31, 1995,  total debt on the Berg  Properties  increased by
$4.0  million,  capital  contributions  increased by $9.3  million,  and capital
distributions decreased by $0.1 million.

     NON-CASH FINANCING ACTIVITIES.  Non-cash investing and financing activities
for the Berg Properties  consisted of debt  forgiveness  gains of  approximately
$0.6  million and $3.2  million for the years ended  December 31, 1996 and 1995,
respectively,  attributable to the debt forgiveness by Great West Life & Annuity
Insurance  Company.  Transfers  of  construction  in  progress,  reflecting  the
difference in the amount of construction in progress at the beginning and end of
each  period,  were none and $3.1 million for the six months ended June 30, 1998
and 1997,  respectively,  and $6.8  million  and $0.08  million and none for the
years ended December 31, 1997, 1996 and 1995, respectively.

YEAR 2000 ISSUE

     The Company utilizes  computer software for its corporate and real property
accounting  records and to prepare its financial  statements.  The vendor of the
Companys current  principal  software  accounting system has advised the Company
that it will provide,  at no charge, a Year 2000 compliance  software upgrade to
the Company in early 1999. If necessary,  the Company could prepare all required
accounting  entries manually without  incurring  material  additional  operating
expenses.

     Conceivably,   tenants  of  the  Properties  could  experience   delays  in
processing their accounting records and making required lease payments,  if they
encounter Year 2000 compliance  problems.  The Company does not believe that any
such delays would have a material adverse effect on the Company.
    

INFLATION

     Most of the leases with the tenants of the  Properties  require the tenants
to pay all operating  expenses,  including real estate taxes and insurance,  and
increases  in  common  area   maintenance   expenses,   either  directly  or  by
reimbursements paid to the landlord. Such lease provisions  substantially reduce
the Company's  exposure to increases in costs and operating  expenses  resulting
from inflation.

                          DESCRIPTION OF THE PROPERTIES

GENERAL

   
     Prior to the Partnership Closing, the members of the Berg Group and certain
of their Affiliates owned all of the Berg Properties, which consist of 50 sites,
including 58 separate  buildings  aggregating  approximately  3,780,000 rentable
square feet, and all of which are located in Silicon Valley. As the sole general
partner of all of the Operating  Partnerships,  the Company has acquired control
of the Berg  Properties.  The Acquired  Properties,  which  consist of 11 sites,
including  11 separate  buildings  aggregating  approximately  561,000  rentable
square  feet,  also  located  in  Silicon  Valley,  are  owned by the  Operating
Partnerships  and controlled by the Company.  All of the Properties will be held
by the Operating Partnerships after the Berg Acquisition.
    

OVERVIEW OF THE BERG PROPERTIES

   
     All of the Berg  Properties are R&D  Properties,  designed for research and
development,  office and, in some cases,  include space for light  manufacturing
operations with loading docks. The Company  considers all of the Berg Properties
to be "Silicon Valley R&D Properties." Generally, the Berg Properties are one to
four story  buildings  of tilt-up  concrete  construction,  have  parking of 3.5
spaces per thousand square feet, or greater,  clear ceiling heights less than 18
feet, and range in size from 18,000 to 211,000 rentable square feet. Most of the
office  space is open  and  suitable  for  configuration  to meet  the  tenants'
requirements  with the use of movable  dividers.  Approximately 40 of the 58 R&D
Properties are single tenant facilities,  although most have been designed to be
divisible and to be usable by multiple tenants.
    

         The current leases for the Berg Properties typically have terms ranging
from three to ten years.  Most of the leases provide for fixed  periodic  rental
increases.  Substantially  all of the leases are "triple net" leases pursuant to
which the tenant is required to pay substantially all of the operating  expenses
of the Property,  including all maintenance and repairs  (excluding only certain
structural repairs to the building shell), property taxes and insurance. Most of
the leases  contain  renewal  options which allow the tenant to extend the lease
based  on  fixed  rental  adjustments  (which  may be  below  market  ratio)  or
adjustment to then prevailing market rates.

     APPLE PROPERTIES

   
     The Apple Properties  consist of four buildings  located at three locations
in  Cupertino,  California  totaling  376,400  square  feet  occupied  by  Apple
Computer,  Inc.  ("Apple")  for more  than  five  years.  The  Apple  Properties
represent  approximately  8.67% of the  total  rentable  square  footage  in the
Operating Partnerships. The largest building is a four-story 211,000 square foot
building  located  across the street from Apple's  850,000 square foot corporate
headquarters.  Apple spent  approximately  $14  million in 1992 to renovate  and
upgrade  this  building,  which  is  currently  used  for  software  development
activities.  Apple  also  leases a  three-building  "campus"  complex,  totaling
142,000 square feet, located one-half block from Apple's headquarters  building.
Apple spent  approximately  $10 million to renovate and upgrade this facility in
1991 and currently  uses this building for  engineering  activities.  Apple also
leases a 23,400 square foot building in Cupertino,  California approximately two
miles from Apple's corporate  headquarters.  This facility is currently used for
prototype manufacturing. None of the Apple Properties is sublet or unoccupied.
    

     The  effective  annual  rent per square foot for the Apple  Properties  was
$11.42, $12.98,  $13.12, $13.23 and $15.79 for 1993 through 1997,  respectively.
The total income tax basis in the Apple Properties was $3,787,722 as of December
31,  1997.   Depreciation   has  been  recorded  for  tax  purposes   using  the
straight-line  method over the useful  lives of the  respective  assets from the
dates they were  placed in service,  which have  ranged from 5 to 45 years.  The
annual  property  taxes,  including   assessments,   for  the  Apple  Properties
aggregated approximately $418,000 for the year ended December 31, 1997, based on
a tax rate of approximately 1.08% plus assessments.

     DESCRIPTION  OF  TENANT.  Apple is a  Fortune  500  company  and one of the
largest  computer  firms in the  world.  As of March 31,  1998,  Apple  employed
approximately  10,000  people,  and its  total  annual  revenues  for 1997  were
approximately $7 billion.  Apple's Cupertino headquarters building was completed
in  1993  at an  estimated  cost of $200  million,  and  the two  largest  Apple
Properties are the buildings located closest to Apple's headquarters.

     LEASE TERMS. The lease for the four-story building expires on May 31, 2002.
The lease  currently  provides for rental payments of $4,338,840 per year ($1.71
per  square  foot per  month).  Apple has the  option to extend the term of this
lease for two successive  five-year periods,  subject to fixed rent adjustments.
The lease for the three-building campus expires on December 31, 2002. This lease
currently provides for rental payments of

                                     -47-
<PAGE>

$1,975,382  per year ($1.16 per square foot per month).  Apple has the option to
extend the term of this lease for five years,  subject to an  adjustment  of the
rental to market rates. The lease for the 23,400 square feet building expires on
November 30, 1998. This lease currently provides for rental payments of $351,702
per year ($1.25 per square foot per month). There are no termination, relocation
or buy-out rights in favor of Apple under any of these leases.

     AMDAHL PROPERTIES

   
     The Amdahl Properties comprise a 260,000 square foot office complex of five
buildings located in the Oakmead Business Park in Sunnyvale,  California and two
buildings of 125,000 square feet and 75,000 square feet,  respectively,  located
in Santa Clara,  California  about two miles from the Sunnyvale  complex.  These
properties are occupied by Amdahl Corporation ("Amdahl").  The Amdahl Properties
represent  approximately  10.6% of the  total  rentable  square  footage  in the
Operating Partnerships. Amdahl utilizes the Sunnyvale facility for its corporate
headquarters   and  the  Santa  Clara  facility  for  research  and  development
activities. These buildings were built between 1972 and 1983 under build-to-suit
arrangements with Amdahl.  Amdahl has sublet approximately 23,000 square feet of
one of the Santa Clara buildings.
    

     The  effective  annual rent per square foot for the Amdahl  Properties  was
$6.63,  $6.86, $7.16, $7.16 and $7.20 for 1993 through 1997,  respectively.  The
total income tax basis in the Amdahl  Properties  was  $7,192,570 as of December
31,  1997.   Depreciation   has  been  recorded  for  tax  purposes   using  the
straight-line  method over the useful  lives of the  respective  assets from the
dates the assets  were placed in  service,  which range from 5 to 45 years.  The
annual  property  taxes,  including  assessments,   for  the  Amdahl  Properties
aggregated approximately $402,000 for the year ended December 31, 1997, based on
an average tax rate of approximately 1.04% plus assessments.

     DESCRIPTION OF TENANT.  Amdahl is a major  international  computer company,
and a wholly  owned  subsidiary  of Fujitsu  Limited.  As of December  31, 1997,
Amdahl employed  approximately  9,900 people and its total revenues for the year
were approximately $1.6 billion.

     LEASE TERMS. The leases for five of the buildings,  totaling 260,000 square
feet,  expire in the first half of 1999.  These  leases  currently  provide  for
aggregate annual rent of $1,061,592 ($0.34 per square foot per month). The lease
for the 125,000  square foot  building  in Santa Clara  expires on November  30,
2008. Currently, annual rental for this building totals approximately $1,104,698
during 1998 and  increases  by 5% every  seven years  ($0.74 per square foot per
month  before  adjustments).  The lease for the  remaining  75,000  square  foot
building expires on April 14, 2004.  Currently,  annual rental for this facility
is $1,157,085 ($1.29 per square foot per month). The leases contain 14 five-year
options remaining with rental rates increasing at pre-negotiated  increments for
each option  period.  The Company  believes that the rental rates for all of the
Amdahl  Properties  are  significantly  below  present  market  rates,  and  the
pre-negotiated  rate  adjustments  will not necessarily bear any relationship to
present or future market rates. There are no termination,  relocation or buy-out
rights in favor of Amdahl under any of the leases.

     CISCO PROPERTIES

   
     The Cisco Properties  consist of two buildings  presently occupied by Cisco
Systems,  Inc.  ("Cisco").  One  of  the  buildings  is a  200,484  square  foot
build-to-suit  building located in south San Jose completed in January 1996. The
other building,  which is located in Santa Clara,  totals 65,780 square feet and
was acquired in 1996 and leased to Cisco effective  February 1, 1997. The larger
facility is used by Cisco as a major  manufacturing and research and development
site. The Cisco Properties  represent  approximately 6.13% of the total rentable
square footage in the Operating Partnerships.
    

     The  effective  annual  rent per square foot for the Cisco  Properties  was
$10.20  for  1997.  The total  income  tax  basis in the  Cisco  Properties  was
$14,299,768  as of December 31,  1997.  Depreciation  has been  recorded for tax
purposes using the straight-line  method over the useful lives of the respective
assets from the dates the assets were placed in service,  which  approximate  40
years for these improvements.  The annual property taxes, including assessments,
for the Cisco Properties aggregate  approximately  $259,185 based on the 1997-98
real  property  tax  bills,  with tax rates  ranging  from  1.09% to 1.14%  plus
assessments. Cisco is in the process of completing certain improvements

                                     -48-
<PAGE>

at the  smaller  facility  which  will  likely  result  in a real  property  tax
reassessment  of this  property.  Any  increase in taxes  associated  with these
improvements during the lease term is Cisco's responsibility.

     DESCRIPTION OF TENANT. Cisco is a publicly traded computer network products
manufacturer.  As of July 31,  1997,  Cisco  employed  over 11,000  people.  Its
revenues  grew by 57.2% over the prior year and its total  revenues for its 1997
fiscal year were approximately $6.44 billion.

     LEASE  TERMS.  The lease for the 200,484  square foot  building  expires on
December 31, 2002.  The current  annual rental is  $2,033,580  ($0.85 per square
foot per month) with fixed periodic  increases.  Cisco has an option to purchase
this property and has the first right of option to lease or purchase  additional
buildings  to be  constructed,  if any, on property  adjacent to the location of
this building.  The purchase  option must be exercised  during  defined  periods
during the lease term at fixed prices. Cisco has two five-year options to extend
the term of its existing lease at fixed annual rent increases.

     The lease for the 65,780 square foot building  expires on January 31, 2000.
The current rent for this property is $907,764 ($1.15 per square foot per month)
with no rental  increases  over the  initial  term of the  lease.  Cisco has one
option  to  extend  the term of this  lease  for a period of one year at a fixed
rental increase.

OTHER MAJOR TENANTS

   
     The  other  nine  of the  twelve  major  tenants  for the  Berg  Properties
currently  lease  R&D  Properties   under  11  separate  leases  which  comprise
approximately  21.63%  of the  Operating  Partnerships'  total  rentable  square
footage.  None of the nine  tenants  accounts  for more than 3.3% of Annual Base
Rent for the Berg  Properties  or more than 3.47% of the total  rentable  square
footage of all Properties.  The Company believes that all nine tenants currently
are in good financial condition. The Company is unaware of any material defaults
under any of their leases.  Each of such tenants has signed a form of the Berg &
Berg standard lease  agreement.  If any of these tenants were to vacate the Berg
Properties that they currently lease or otherwise  terminated  their  tenancies,
the Company  believes  that it could obtain new tenants at  comparable or higher
rents within three months, in light of the current market for Silicon Valley R&D
Properties.  See "THE BUSINESS OF BERG & BERG--The  Silicon  Valley R&D Property
Market."

five-year options for the tenant to extend the lease at market rental rates, but
not  less  than the rent in the last  month of the  original  term.  Most of the
leases contain provisions similar to the following:

     - Except to the extent caused by the sole negligence or willful  misconduct
of the  lessor,  the  tenant  is  required  to fully  indemnify  Berg & Berg for
property related actions, suits, proceedings or the like, including any actions,
suits or  proceedings  relating  to  hazardous  materials.  The  indemnification
provisions survive the termination of the lease.

     - The tenant may not assign the lease or sublet the  premises  without  the
prior  written  consent  of Berg & Berg,  except  to a bona  fide  affiliate  or
subsidiary of the tenant.  In recent leases,  Berg & Berg has reserved the right
to withhold  consent to any  proposed  assignment  or  sublease if the  proposed
assignee or sublessee is a generator of hazardous  materials.  Regardless  of an
assignment or sublet  permitted,  the tenant  remains  primarily  liable for the
performance of all conditions, covenants and obligations under the lease.

     - Berg & Berg  generally  does not require the tenant to obtain  earthquake
insurance.

OVERVIEW OF THE ACQUIRED PROPERTIES

     All of the Acquired  Properties are R&D Properties.  They are occupied by a
total of 10 tenants under leases with terms ranging from 4 to 13 years.  Most of
the leases provide for fixed periodic  rental  increases.  All of the leases are
triple net leases.  Most of the leases contain  renewal  options which allow the
tenant to extend the lease based on fixed rental adjustments (which may be below
market ratio) or adjustment to then prevailing market rates.

     L'AVENIDA.  This Mountain View,  California project will be a five-building
complex  totaling  approximately  513,000  square  feet on nearly 30 acres.  The
buildings  will  be  high-quality   contemporary  tilt-up  R&D  Properties  with
reflective glass and concrete  exteriors  designed  primarily as headquarters or
research and development  facilities for software or  biotechnology  firms.  The
site is a prime location near U.S. Highway 101, and neighboring  tenants include
Alza Corporation, Sun Microsystems,  Inc. and Silicon Graphics, Inc. BBE expects
to complete and lease all of the buildings in mid-1999.  On August 6, 1998, Berg
& Berg and  Microsoft  signed a lease  with  respect to an  approximate  515,000
square foot  property to be  constructed  by  Microsoft on L'Avenida in Mountain
View, California,  one of the sites comprising the Pending Development Projects.
This is a triple  net lease with base rent in the first year of $2.95 per square
foot.  Microsoft controls the construction of this facility,  which is scheduled
to be completed in phases between March and May 1999.

     THE PENDING PROJECTS ACQUISITION AGREEMENT.  The Acquisition Agreement,  as
amended, provides for the Company, the Operating Partnerships and the members of
the Berg Group holding  interests in the Pending  Development  Projects to enter
into the Pending  Projects  Acquisition  Agreement  for the  acquisition  of the
Pending Development Projects by the Operating  Partnerships at the final closing
date for the Berg  Acquisition.  Currently,  there are no tenants for any of the
Projects. Following are the principal terms of that agreement:
    

          -    The  selling  Berg Group  members  and BBE will build and deliver
               each R&D  Property  in the  Pending  Development  Projects to the
               Operating Partnerships at the acquisition  value set forth in the
               following  table,  subject to  adjustment  if the actual  average
               monthly  rental rate per square foot differs  from the  projected
               rental rate set forth in the table. The actual  acquisition value
               will be equal to the  actual  Annual  Base  Rent  divided  by the
               capitalization  rate,  minus the amount of debt  encumbering  the
               property.

(1)  Calculated  as 100 divided by the  quotient of the  Purchase  Price and the
     Projected  Triple Net Annual  Base Rent.  Management  believes  the current
     capitalization  rate for good  quality  Silicon  Valley R&D  Properties  is
     approximately 0.085 to 0.095.

(2)  This  project  provides  an  unusually  high  rate  of  return  and  is not
     representative  of  returns or  projects  that the  Company  may be able to
     obtain or acquire in the future.

          -    The  acquisition  value  will be  payable  by the  Company or the
               Operating  Partnerships  in L.P.  Units at $4.50 per L.P. Unit or
               cash, at the option of the Sellers.

          -    The closing for the  acquisition  of an  individual  R&D Property
               within the  Project  will occur only when the  building  has been
               completed  and  fully  leased.  The  Company  and  the  Operating
               Partnerships  are not  otherwise  required  to acquire any of the
               Pending Development Projects.

          -    The sellers will make customary representations and warranties to
               the Operating Partnerships as of the closing date.

          -    Leases will be on commercially  reasonable  terms and conditions.
               See "Standard Berg & Berg Lease Terms."

   
     The Company will acquire the R&D Properties to be built by Microsoft on the
L'Avenida  site when and if  construction  has been  completed and the buildings
have been fully leased,  and provided that the  shareholders of the Company have
approved the Pending  Projects  Acquisition  Agreement  at the Special  Meeting.
There can be no assurance that Microsoft will complete this facility, and unless
all of the foregoing events occur, the Company will have no right to acquire the
L'Avenida Pending Development Project, or any interest therein.

LAND HOLDING AND DEVELOPMENT ARRANGEMENTS

   
     BERG LAND HOLDINGS.  Certain  members of the Berg Group,  including Carl E.
Berg,  own  the  Berg  Land  Holdings,  which  consist  of  several  parcels  of
undeveloped  real estate in the Silicon Valley which have been made available to
the  Company  for future  development,  subject to  stockholder  approval at the
special  meeting,  under the terms of the Option  Agreement.  Mr.  Berg and such
other Berg Group members have not  undertaken  any  obligation to the Company or
the Operating Partnerships to exercise any of their options or rights to acquire
or  develop  the Berg Land  Holdings  and may not  exercise  them prior to their
current expiration dates. The following table describes the Berg Land Holdings:

(1)  Net acres
    


(2) Assumed coverage ratio of 32-35% of the buildable portion of the parcel.

     All three  parcels have  industrial  or  industrial  business  park zoning,
permitting the development of R&D Properties.  All  discretionary  approvals for
the King Ranch, and Hellyer and Piercy  properties have been obtained,  with the
exception of  discretionary  architectural  reviews.  Development of each of the
parcels  also  requires  various  administrative  and  ministerial  permits  and
approvals prior to the commencement of construction.

     The King Ranch site is adjacent to U.S. Highway 101. To date,  designs have
been prepared for two buildings of approximately  110,000 square feet and 70,000
square feet, respectively.

     Certain  members of the Berg Group hold an option to  purchase  the site at
Fremont  Avenue and  Cushing  Boulevard  in  Fremont,  California,  exercisable,
including  all  extensions,  prior to January 2000.  Acquisition  of the land is
subject to receipt of building  permits and the resolution of issues  concerning
the set aside of wetlands.  The Berg Group intends to propose offsite mitigation
to the Army Corps of  Engineers.  If this  mitigation  cannot be  obtained,  the
buildable site would be reduced to  approximately  22 acres and 335,000 rentable
square  feet.  The  optionholders  may decide not to  exercise  their  option to
acquire  this land,  in which case it will no longer be subject to the Berg Land
Holdings Option Agreement.

     Certain  members of the Berg Group  hold an option to  purchase  the parcel
located at Hellyer  Avenue and Piercy  Road in south San Jose during  1998.  The
acquisition  of the land is  subject  to receipt  of  building  permits  and the
resolution  of  street  improvement  costs  with  the  City  of  San  Jose.  The
optionholders  may decide not to exercise  their right to acquire this property,
in which  case it will no longer be  subject  to the Berg Land  Holdings  Option
Agreement.

     THE OPTION AGREEMENT.  The Acquisition Agreement, as amended,  provides for
the  Company,  the  Operating  Partnerships  and the  members  of the Berg Group
holding  interests in the Berg Land Holdings to enter into the Option  Agreement
containing the following  principal terms at the final closing date for the Berg
Acquisition:

   
     -    After the  effective  date of the Option  Agreement and for as long as
          the Berg Group members and their  Affiliates  own or have the right to
          acquire shares representing 65% of the Common Stock on a Fully-Diluted
          basis,  the Company will have the option (the "Option") to acquire any
          building  developed  by any  member of the Berg Group on the Berg Land
          Holdings  at such  time as the  building  has  been  leased.  Upon the
          Company's  exercise of the Option the option  price will equal the sum
          of (i) the full  construction  cost of the building,  plus (ii) 10% of
          (i),  plus  (iii)  the  acquisition  value of the  parcel on which the
          improvements  were constructed as set forth in the schedule below, and
          interest on that amount at LIBOR from  January 1, 1998 until the close
          of escrow,  plus (iv) taxes and  assessments  prorated from January 1,
          1998,  plus (v) interest at LIBOR on the amounts  described in clauses
          (i) and (iv) from the date  paid by the  developer  and  ending at the
          close of  escrow,  minus the  aggregate  principal  amount of all debt
          encumbering  the  acquired  property.  The  acquisition  value of each
          parcel under the Option Agreement follows:

     -    The purchase price will be payable in cash, unless otherwise agreed by
          the Berg Group  representatives,  and the Company may contribute  such
          building to the Operating  Partnerships,  subject to any debt incurred
          in connection with the acquisition, in exchange for additional general
          partner  interests in the Operating  Partnerships  based up the market
          value of the Common Stock over the 30-trading day period preceding the
          Company's exercise of the Option.

     -    The Company also must assume all assessments.

   
     -    If the Company  elects not to exercise  the Option with respect to any
          building,  the Berg Group may hold and lease the  building for its own
          account, or may sell it to a third party.

     -    All action by the Company under the Option  Agreement must be approved
          by a majority of the members of the Independent Directors Committee.

     NON-COMPETITION  ARRANGEMENTS.  Mr.  Berg has  advised  the  Company of his
intention to conduct all of his material R&D Property investment and development
activities  through the Company,  except with respect to the Berg Land Holdings,
which are subject to the Option Agreement, and the Pending Development Projects,
which are subject to the Pending Projects  Acquisition  Agreement.  Accordingly,
under the  Acquisition  Agreement,  he has agreed not to directly or  indirectly
acquire or develop,  or acquire an equity ownership  interest in any entity that
has or intends to acquire an  ownership  interest in any real  estate  (with the
exception  of minor  investments  not to exceed  10% of the  outstanding  voting
securities in publicly-traded  companies) intended for R&D Property  development
or similar  industrial  use in  California,  Oregon or Washington  without first
disclosing  such   investment   opportunity  to  the  Company  and  making  such
opportunity  available to the Company at the option of the Independent Directors
Committee.  Generally,  Mr.  Berg and the other Berg Group  Members  are free to
pursue other types of real estate  activities and other business  opportunities,
however. See "THE ACQUISITION AGREEMENT--Conflicts of Interest Provisions."

MORTGAGE DEBT AND CREDIT LINES

   
     MORTGAGE DEBT. The following table sets forth certain information regarding
the mortgages  encumbering the Berg Properties upon the consummation of the Berg
Acquisition,  assuming the application of the proceeds therefrom as set forth in
"Use of Proceeds" and that such proceeds were applied  effective as of September
30, 1998. All mortgage debt is nonrecourse to the Company,  although  certain of
the mortgages are cross-defaulted and cross-collateralized  with other mortgaged
Properties.

     On September 23, 1998, the Company,  in its capacity as the general partner
of the  Operating  Partnerships,  obtained a 130  million  loan from  Prudential
Insurance Company of America. This loan is cross-collateralized and secured by a
single deed of trust  encumbering  18 properties  improved with 24 buildings and
consisting of  approximately  1.7 million square feet of space, all of which are
owned by the Operating  Partnerships.  The interest rate on the loan is fixed at
6.56% per annum, the  amortization  period is 30 years, and the term of the loan
is 10 years. There is a significant prepayment penalty if the loan is paid prior
to the maturity date. The loan is nonrecourse to the Operating  Partnerships and
the  Company,  except  with  respect to certain  matters  such as  environmental
liability  relating  to the  encumbered  properties,  the  payment  of taxes and
assessments with respect to the encumbered  properties,  the  responsibility  to
return security deposits to the tenants of the encumbered properties,  insurance
or  condemnation  proceeds that are not properly  applied under the terms of the
loan, damages that result from early termination or amendment to specified major
leases, waste of the subject properties,  bankruptcy or insolvency of any of the
Operating  Partnerships or the Company, and any fraud or  misrepresentations  by
the  Company or the  Operating  Partnerships  in  connection  with the loan.  In
addition, portions of the loan are guaranteed by certain Limited Partners.

     CREDIT LINES.  Historically,  some of the Berg Properties have been pledged
as  collateral  under a line of credit  provided by Wells Fargo,  which has been
guaranteed by the Berg Group  members.  As of September 30, 1998,  approximately
$39 million was outstanding  under the Wells Fargo Line,  which is secured by 14
Properties.  The Berg Group members  remain parties to the Wells Fargo Line, but
have assigned to the Company and Operating  Partnerships  all of their borrowing
rights under the Wells Fargo Line. See "FUTURE OPERATIONS OF THE COMPANY -- Line
of Credit."
    

PROPERTY TAX INFORMATION

   
     The  aggregate  real estate  property tax  obligations  paid by the Company
(with or without tenant  reimbursement)  for the Berg Properties during calendar
1997 were approximately  $4.2 million.  This amount does not include real estate
property  taxes paid directly by tenants.  Of the four  Operating  Partnerships,
only MWP had any Properties  transferred to it as part of the Berg  Acquisition;
the other three limited partnerships have retained their historical  Properties.
The Property transfers to MWP resulted in a statutory change in ownership giving
rise to a reassessment  for California real property tax purposes,  which is not
expected  to have a  material  adverse  impact on the  operations  or  financial
condition of the Company.
    

     Except as noted with respect to transfers of Properties to MWP, the Company
does not  believe  that any other  aspects of the UPREIT  Transactions  effect a
statutory  change in ownership.  Nevertheless,  there can be no assurance that a
local assessor will not assert that the UPREIT  Transactions  also have resulted
in a statutory  change in ownership with respect to the Berg  Properties held by
MWP I,  MWP II and MWP III,  as  county  assessors  in  California  occasionally
challenge  complex  transactions  in which new  investors  acquire  interests in
existing real property holding entities. Substantially all of the leases for the
Properties  contain  provisions  requiring the tenants to pay as additional rent
their  proportionate  shares of any property tax increases  over  specified base
amounts.  The  Company  may not be able to pass  through to its tenants the full
amount of any  increased  taxes  resulting  from a  reassessment,  however.  The
Company  believes that any amount that cannot be passed  through to tenants will
not have a material adverse effect on the Company.

ENVIRONMENTAL MATTERS

     Under various federal, state and local laws, ordinances and regulations, an
owner or operator of real  property  may be held liable for the costs of removal
or remediation  of certain  hazardous or toxic  substances  located on or in the
property.  Such laws often impose liability and expose the owner to governmental
proceedings,  without  regard to whether  the owner knew of, or was  responsible
for,  the  presence  of the  hazardous  or toxic  substances.  The  costs of any
required  remediation  or  removal of such  substances  may be  substantial.  In
addition,  the owner's  liability as to any specific  property is generally  not
limited and could exceed the value of the property  and/or the aggregate  assets
of the owner. The presence of such substances, or the failure to properly remove
or remediate such  substances,  may also adversely affect the owner's ability to
sell or rent the property or to borrow using the property as collateral. Persons
who arrange for the treatment or disposal of hazardous or toxic substances, such
as  asbestos,  at a  disposal  facility  may also be liable for the costs of any
required  remediation  or removal of the  hazardous or toxic  substances  at the
facility,  regardless of whether the facility is owned or operated by such owner
or entity.  In connection  with the ownership of the Properties or the treatment
or disposal of hazardous or toxic substances, the Company may be liable for such
costs.

     Other  federal,  state and local laws impose  liability  for the release of
ACMs  into the air and  require  the  removal  of  damaged  ACMs in the event of
remodeling  or  renovation.  The Company is aware that there are ACMs present at
several of the Properties,  primarily in floor  coverings.  The Company believes
that the ACMs present at these  Properties  are generally in good  condition and
that no ACMs are present in the remaining Properties. The Company believes it is
in  compliance in all material  respects with all federal,  state and local laws
relating to ACMs and that if it were  required to remove all ACMs present at the
Properties  over a short period of time, the cost of such removal would not have
a material  adverse effect on its financial  condition,  operating  results,  or
ability to make distributions.

     The  Company is not aware of any  environmental  liability  relating to the
Properties  that  it  believes  would  have a  material  adverse  effect  on its
financial condition,  its operating results or its ability to make distributions
and has not been notified by any  governmental  authority or any other person of
any material  noncompliance,  liability or other claim in connection with any of
the  Properties.  No  assurance  can be given that future  laws,  ordinances  or
regulations  will not impose  material  environmental  liabilities,  or that the
current  environmental  condition  of the  Properties  will not be  affected  by
tenants and occupants of the Properties,  by the uses or condition of properties
in the vicinity of the Properties, such as leaking underground storage tanks, or
by third parties unrelated to the

                                     -60-
<PAGE>

Company. If the Company is required to remove or remediate any toxic wastes
or hazardous substances present on any of the Properties, the cost to the
Company could be material.

LEGAL PROCEEDINGS

     From time to time the Company is involved in legal  proceedings  arising in
the ordinary  course of its business,  none of which is believed to be material.
The  Company  is not  aware  of any  material  litigation  affecting  any of the
Properties,  the Pending Development  Projects,  the Berg Land Holdings,  or the
Operating Partnerships, except for anticipated litigation concerning the Fremont
Properties.  See "SUMMARY OF THE UPREIT  TRANSACTIONS AND PURPOSE OF THE SPECIAL
MEETING  --  Parties  to and  Terms of the Berg  Acquisition."  Berg & Berg is a
plaintiff in BERG & BERG v. CHERYL AND GILBERT  CHAVEZ in the Santa Clara County
Superior Court.  The court has entered a default judgment against the defendants
in that action to recover  funds  embezzled by a former  employee of Berg & Berg
and BBE. Neither the Company nor the Operating  Partnerships are entitled to any
funds that may be recovered pursuant to the judgment.

EMPLOYEES

     The  Company  initially  expects  to employ  five  persons.  The  Operating
Partnerships  will not  have any  employees.  Prior to the  consummation  of the
UPREIT Transactions, three of the Company's employees were employed by BBE.

                        FUTURE OPERATIONS OF THE COMPANY

OVERVIEW

   
     Upon  consummation  of the  UPREIT  Transactions,  the  Company  will  be a
fully-integrated,  self-administered and self-managed REIT organized to continue
and expand the business of acquiring,  developing,  owning and managing  Silicon
Valley R&D Properties currently conducted by the Berg Group. Through its general
partnership  interests  in the  Operating  Partnerships,  the  Company  owns and
operates  69 Silicon  Valley R&D  Properties.  As of  September  30,  1998,  the
occupancy rate of the Properties  was  approximately  100%. The Company also may
acquire the 12 Silicon Valley R&D Properties  comprising the Pending Development
Projects  if they are built  and fully  leased,  and has the  Option to  acquire
additional  Berg Group  Silicon  Valley R&D  Properties  pursuant  to the Option
Agreement.

     Consequently, the Company's principal focus upon consummation of the UPREIT
Transactions  will be the management of its Silicon Valley R&D Properties.  With
Silicon  Valley's  highly  educated  and skilled work force,  recent  history of
numerous successful start-up companies,  and large contingent of venture capital
firms,  the Company  believes that this region will continue to spawn successful
new high-growth  industries and entrepreneurial  businesses to an extent matched
nowhere else in the United States.

     In 1996, according to the National Venture Capital Survey,  venture capital
investment in the Silicon Valley reached $2.3 billion, representing 24.1% of the
total of $9.5  billion  invested  nationally.  Most of the  investments  were in
technology-based  companies,  particularly in  communications  and software.  In
1997, total venture capital  investment in Silicon Valley exceeded $3.3 billion.
Successful,  venture capital-backed  technology companies typically seek further
capital from the public capital markets.  Initial public  offerings  ("IPOs") by
companies in the San Francisco Bay Area raised over $2.2 billion,  $2.1 billion,
and $1.7  billion  in 1995,  1996,  and  1997,  respectively.  The IPO  proceeds
frequently are used to fund growth and  expansion,  with a resulting need on the
part of the issuer for  additional  space.  Although  equity  valuations and the
availability of private and public capital fluctuate  considerably,  the Company
believes  that this  investment  cycle will  continue  to create  favorable  R&D
Property development and rental opportunities in the Silicon Valley.
    

OPERATING AND GROWTH STRATEGY

     The Company intends to employ Berg & Berg's  historical  business  strategy
and the Company's  substantial resources to achieve growth in FFO. The Company's
operating and growth strategy contains the following principal elements:

         -        Continued emphasis on general purpose,  single-tenant  Silicon
                  Valley  R&D  Properties  for  technology-based   companies  to
                  capitalize  on  the  Company's  extensive  contacts  in  these
                  companies  and its  extensive  knowledge  of their real estate
                  needs.

                                     -61-
<PAGE>

         -        Acquiring R&D  Properties  built by the Berg Group on the Berg
                  Land  Holdings,   which  now  represent  one  of  the  largest
                  aggregations of land available for future  construction of R&D
                  Properties in Silicon Valley.

         -        Demand-driven     development     activities,      emphasizing
                  build-to-suit  projects for  existing and emerging  technology
                  companies experiencing growth in the Silicon Valley.

         -        Opportunistic  acquisitions  of  high  quality,   well-located
                  Silicon Valley R&D Properties in situations where  illiquidity
                  or inadequate management permit their acquisition at favorable
                  prices,  and  where  the  Company's   management  skills  will
                  facilitate increases in cash flow and asset value.

         -        Maintenance of a lean,  experienced and responsive  management
                  team   comprised   of   highly   qualified   and   experienced
                  professionals  working within a relatively flat organizational
                  structure.

         -        Prudent financial management emphasizing current cash flow, as
                  well as  long-term  value  in the  Company's  acquisition  and
                  financing  policies,  the  pre-leasing  of buildings  prior to
                  acquisition  or development to reduce the risks of owning them
                  and the  maintenance  of  sufficient  liquidity to acquire and
                  finance properties on desirable terms.

         -        Geographic expansion into other  technology-based areas of the
                  West Coast if good R&D Properties become available there.

OPERATIONS AND MANAGEMENT

     The Company will operate as a self-administered, self-managed REIT with its
own employees.  It will sublease  office space from Berg & Berg at 10050 Bandley
Drive and will  share  clerical  staff and other  overhead  on what the  Company
considers  to be very  favorable  terms.  The total  monthly rent payable by the
Company to Berg & Berg will be $5,625,  and the  Company's  contribution  to BBE
overhead  when added to the rent payable to Berg & Berg will not exceed  $15,000
per  month.  Carl E. Berg will work for the  Company,  as well as BBE,  and will
provide  services to other  enterprises.  The other  employees  of the  Company,
except Bradley A. Perkins, will work for the Company full-time.  The Company may
add two additional  employees,  as required,  but does not anticipate  growth in
employment  except as  acquisitions  of new  properties,  particularly  in other
geographic regions, require additional personnel.

   
     Construction  and repair  work at the  Company's  Properties  for  building
maintenance and tenant improvements may be provided by BBE. The Company will bid
all major work competitively to subcontractors, however.
    

     The Company  generally will market the Properties and negotiate leases with
tenants by itself.  Occasionally,  the  Company  expects to retain  real  estate
brokers, and its policy is to pay fixed commissions to tenants' brokers.

ACQUISITIONS

   
     The  Company's   principal   acquisition   opportunities  are  the  Pending
Development  Projects  and  the  acquisition  of  R&D  Properties  that  may  be
constructed  by the Berg  Group on the Berg Land  Holdings.  The Berg  Group has
acquired  approximately 580,000 square feet of buildings in the last four years.
The Company believes its acquisitions  experience and the network of real estate
professionals  it has done business with will continue to provide  opportunities
for  external   growth.   Furthermore,   the  Company's  use  of  the  Operating
Partnerships  structure gives prospective  sellers the opportunity to contribute
properties to the Company (through the Operating Partnerships) on a tax-deferred
basis in  exchange  for L.P.  Units.  This  capacity  to  complete  tax-deferred
transactions  with sellers of real property  will further  enhance the Company's
ability to acquire  additional  properties.  Management  also intends to monitor
available,  well-located,  industrial properties on the West Coast of the United
States.

MORTGAGE INDEBTEDNESS OUTSTANDING AFTER BERG ACQUISITION

     In addition to the $130 million  Prudential  Secured Loan which  matures on
October 15, 2008, the Company had other secured loans totaling approximately $90
million outstanding at September 30, 1998, including $39 million under the Wells
Fargo Line. See "MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF  OPERATIONS  FOR THE  PROPERTIES  -- Pro Forma  Liquidity and Capital
Resources" and "DESCRIPTION OF THE PROPERTIES--Mortgage Debt and Credit Lines."

                               DISTRIBUTION POLICY

OVERVIEW

     The Company intends to make regular  quarterly  distributions to holders of
its Common Stock based on its Cash  Available  for  Distribution.  The Company's
ability  to  make  such  distributions  will be  affected  by  numerous  factors
including,  most  importantly,  the receipt of distributions  from the Operating
Partnerships.  The first  distribution  for the period  commencing  at the final
closing  date for the Berg  Acquisition  and  ending on  September  30,  1998 is
expected to be in an amount equivalent to a quarterly distribution of $0.085 per
share (which, if annualized,  would equal $0.34 per share, or an annual yield of
8%,  based  on the last  trading  price  set  forth  on the  cover  page of this
Prospectus/Proxy Statement).

   
     In general,  the Company expects that Cash Available for Distribution  will
exceed its initial  planned  distributions.  Expected  distributions  for the 12
months  following  the  final  closing  date  for the Berg  Acquisition  will be
approximately  83% of the  estimated  Cash  Available  for  Distribution  of the
Company  and are  expected to exceed 95% of the  Company's  taxable  income,  as
determined  under federal tax laws applicable to REITs.  The amount of estimated
Cash  Available  for  Distribution  is based on the net amount of pro forma cash
provided/(used) by operating,  investing and financing activities of the Company
for all of the Properties for the twelve months ending September 30, 1999, which
includes adjustments for certain known events occurring after September 30, 1998
that are not  reflected  in the  Company's  historical  or pro  forma  financial
statements.

</TABLE>


     In order to effect the  closing of the  Company's  acquisition  of the sole
     general partnership  interests in the Operating  Partnerships,  the Company
     issued to each of the partnerships a demand note bearing interest at a rate
     of 7.25% per annum aggregating $35,200 in principal. At September 30, 1998,
     the outstanding balance on these notes was $33,869. Upon the closing of the
     new Private  Placement,  the Company will utilize those proceeds along with
     available  cash and a draw of $2,941  on the line of credit to repay  these
     notes in their entirety.

     The portion of the outstanding  balance on the line of credit in the amount
     of $2,941 will be the sole responsibility of the Company until such time as
     the balance is paid in full.  Additionally,  the full amount of interest on
     any outstanding  balance  associated with this amount will be absorbed 100%
     by the Company.  On a pro forma basis,  interest  expense on this amount is
     $213 for the twelve months ended September 30, 1999.

     Until such time that the  Company  completes  the  Private  Placement,  the
     Company's  share of Cash Available for  Distribution  will be less than the
     amount  calculated  in this table.  Any  outstanding  balances  owed to the
     Operating  Partnerships  in excess of $2,941  will  increase  the  minority
     interests' share cash available for distribution by an amount 87.89% of the
     interest  income  associated  with such  balances,  thereby  decreasing the
     Company's share of such amounts.

(7)  The  estimated  annual  distribution  per  share  is  based  on a total  of
     8,193,594  shares  outstanding  after the UPREIT  Transactions  assuming no
     dilution from the exchange of L.P. Units,  or exercise of options  pursuant
     to the terms of the 1997 Stock Option Plan.

(8)  The payout ratio on estimated Cash Available for Distribution is calculated
     as the  estimated  initial  annual  distribution  per share  divided by the
     Company's  share of Cash  Available for  Distribution  per share for the 12
     months ending September 30, 1999.
    

     The Company  believes that its estimate of Cash Available for  Distribution
constitutes a reasonable  basis for setting the amount of the Company's  initial
distribution  and expects to maintain its initial  distribution  rate for the 12
months following the closing of the Berg  Acquisition,  unless actual results of
operations,  economic  conditions or other factors  differ  materially  from the
assumptions  used in the  estimate.  Cash  Available for  Distribution  does not
represent cash generated from operating  activities in accordance  with GAAP and
is not necessarily  indicative of cash available to fund cash needs.  The actual
return that the Company will realize and the amount available for  distributions
to shareholders will be affected by a number of factors,  including the revenues
received  from the  Properties,  the  operating  expenses  of the  Company,  the
interest expense incurred on borrowings and unanticipated  capital expenditures.
The  estimate  of Cash  Available  for  Distribution  is  provided in this Proxy
Statement/Prospectus  solely for the purpose of setting the initial distribution
amount and is not intended to be a forecast by the Company of its future results
of operations, FFO or Cash Available for Distribution. No assurance can be given
that the Company's estimate will prove accurate.

     The Company  anticipates that Cash Available for  Distribution  will exceed
earnings and profits for federal  income tax purposes as the latter figure takes
into account non-cash  expenses,  such as depreciation and  amortization,  to be
incurred  by the  Company.  Distributions  by the  Company  to the extent of its
current and  accumulated  earnings  and profits for federal  income tax purposes
will be taxable to shareholders as ordinary dividend income unless a shareholder
is a tax-exempt  entity.  See "FEDERAL  INCOME TAX  CONSIDERATIONS--Taxation  of
United  States  Shareholders".  Distributions  in excess of earnings and profits
generally will be treated as a non-taxable  reduction of the shareholder's basis
in the Common Stock to the extent  thereof,  and thereafter as taxable gain. The
percentage of such  distributions  constituting a non-taxable return of capital,
if any,  may  vary  from  period  to  period.  The  Company  anticipates  that a
substantial  percentage of the  distributions  to shareholders for the 12 months
following the consummation of the Offering will constitute ordinary income.

     In order to maintain  its  qualification  as a REIT,  the Company must make
annual  distributions  to  shareholders  of at least 95% of its  taxable  income
(which  does  not  include  net  capital   gains).   See  "FEDERAL   INCOME  TAX
CONSIDERATIONS--Taxation  of  the  Company--Annual  Distribution  Requirements."
Under certain  circumstances,  the Company may be required to make distributions
in excess of Cash Available for Distribution in order to meet such  distribution
requirements.

     Any inability on the part of the Operating Partnerships to secure financing
as required to fund  capital  expenditures  and net changes in working  capital,
including development  activities and expansions,  would require the utilization
of  distributable  cash  flow to  satisfy  such  obligations,  thereby  possibly
reducing  distributions to partners,  including the Company, and funds available
for the Company to pay dividends.  See "MANAGEMENT'S  DISCUSSION AND ANALYSIS OF
FINANCIAL CONDITION AND RESULTS OF OPERATIONS--Liquidity and Capital Resources."

     Cash Available for  Distribution is based on FFO. The Company  computes FFO
in accordance with standards  established by the Board of Governors of NAREIT in
its  March  1995  White  Paper,  which  may  differ  from  the  methodology  for
calculating   Funds  from  Operations   utilized  by  other  equity  REITs,  and
accordingly, may not be comparable to such other REITs. NAREIT currently defines
FFO as net income (loss) (computed in accordance with GAAP), excluding gains (or
losses) from debt restructuring and sales of property,  plus real estate related
depreciation  and  amortization  (excluding  amortization of deferred  financing
costs and  depreciation  of non-real  estate assets) and after  adjustments  for
unconsolidated partnerships and joint ventures.  Extraordinary or unusual items,
along  with  significant   non-recurring  events  that  materially  distort  the
comparative  measure  of FFO are  disregarded  in this  calculation.  Management
believes that its computation of FFO is helpful to investors as a measure of the
performance  of an equity  REIT  because,  along with cash flows from  operating
activities, financing activities and investing activities, it provides investors
with an  understanding  of the  Company's  ability to incur and service debt and
make  capital  expenditures.  The  Company's  definition  of  FFO  also  assumes
conversion  at the  beginning  of the  period  of  all  convertible  securities,
including  minority  interests  that might be exchanged  for Common  Stock.  The
Company's  FFO  does  not  represent  the  amount   available  for  management's
discretionary  use as such  funds  may be  needed  for  capital  replacement  or
expansion, debt service obligations, or other commitments and uncertainties. FFO
should  not be  considered  as an  alternative  to  net  income  (determined  in
accordance with GAAP) as an indication of the Company's financial performance or
to cash flows from operating activities  (determined in accordance with GAAP) as
a measure of the Company's liquidity, nor is FFO necessarily indicative of funds
available  to fund the  Company's  cash  needs,  including  its  ability to make
distributions.  The Company believes that to facilitate a clear understanding of
the  combined  historical  operating  results  of the  Berg  Properties  and the
Company,  FFO should be examined in conjunction  with net income as presented in
the combined financial statements.

     Distributions  by the Company will be  determined by the board of directors
and will depend on actual Cash Available for  Distribution  of the Company,  its
financial condition, capital requirements,  the annual distribution requirements
under the REIT  provisions  of the Code and such  other  factors as the Board of
Directors deems relevant. For a discussion of the tax treatment of distributions
to   holders   of   shares  of   Common   Stock,   see   "FEDERAL   INCOME   TAX
CONSIDERATIONS--Taxation of United States Shareholders" and "Taxation of Foreign
Shareholders."

     THE ESTIMATES OF PRO FORMA CASH FLOWS FROM  OPERATING  ACTIVITIES  AND CASH
AVAILABLE  FOR  DISTRIBUTION  ARE MADE  SOLELY FOR THE  PURPOSE  OF SETTING  THE
INITIAL DISTRIBUTION RATE AND ARE NOT INTENDED TO BE A PROJECTION OR FORECAST OF
THE COMPANY'S  RESULTS OF OPERATIONS OR OF ITS LIQUIDITY.  FUNDS FROM OPERATIONS
DOES NOT  REPRESENT  CASH  FLOW  FROM  OPERATIONS  AS  DEFINED  BY GAAP,  IS NOT
NECESSARILY  INDICATIVE  OF CASH  AVAILABLE  TO FUND ALL OF THE  COMPANY'S  CASH
NEEDS, AND SHOULD NOT BE CONSIDERED AS AN ALTERNATIVE TO NET INCOME FOR PURPOSES
OF  EVALUATING  THE  COMPANY'S  OPERATING  PERFORMANCE.   SEE  "FORWARD  LOOKING
INFORMATION"  and  "RISK   FACTORS--Uncertainties   Regarding  Distributions  to

                   POLICIES WITH RESPECT TO CERTAIN ACTIVITIES

   
     The  following is a discussion  of the  Company's  policies with respect to
investment,  financing,  conflicts  of  interest  and  other  activities  of the
Company.  These  policies have been  formulated by the board of directors of the
Company  and  generally  may be  amended  or  revised  from  time to time at the
discretion of the board of directors  without a vote of the  shareholders of the
Company.  Upon the effective date of the Reincorporation  Merger,  however,  the
Charter will provide that (i) until the Protective  Provisions  Expiration Date,
the  approval  of the  Required  Directors  as  provided  in the Charter and the
consent of the L.P.  Unit Majority are required for the Company to take title to
assets  (other than  temporarily  in  connection  with an  acquisition  prior to
contributing  such assets to the Operating  Partnerships) or to conduct business
other  than  through  the  Operating  Partnerships,  or for the  Company  or the
Operating  Partnerships  to engage in any  business  other  than the  ownership,
construction,  development and operation of real estate properties, (ii) changes
in certain  policies  with respect to conflicts of interest  must be  consistent
with legal  requirements,  (iii) certain policies with respect to competition by
Carl E. Berg and the Berg  Group  are  imposed  pursuant  to  provisions  of the
Acquisition  Agreement  that cannot be amended or waived without the approval of
the Independent Directors Committee, and (iv) the Company cannot take any action
intended to terminate its  qualification  as a REIT without the approval of more
than 75% of the entire board of  directors.  In addition,  until the  Protective
Provisions  Expiration  Date,  the  approval of the Required  Directors  will be
required for certain fundamental corporate actions,  including amendments to the
Charter or bylaws,  amendments to the Operating Partnership  Agreement,  and any
merger,  consolidation or sale of all or substantially  all of the assets of the
Company or the Operating Partnerships. Certain specific transactions,  including
the issuance of securities  and  borrowings in excess of specified  limits,  and
amendments of the Charter and bylaws are subject to approval by more than 75% of
the  directors.  See  "DESCRIPTION  OF CAPITAL  STOCK--Board  Quorum and Special
Voting Requirements."
    

INVESTMENT POLICIES

     The  Company's   business  will  be  focused   solely  on  the   ownership,
construction,  development and operation of real estate properties,  principally
R&D Properties, and the Company intends to conduct all of its activities through
the  Operating Partnerships.  The Company's  investment  objective is to provide
stable  cash  flow  available  for  quarterly  cash  distributions  and  achieve
long-term  appreciation  through  increases  in cash  flows and the value of its
properties.  The Company  intends to pursue these  objectives  by (i)  investing
capital  to enhance  investment  returns on its  existing  Properties,  and (ii)
acquiring or developing  additional  properties  where the Company believes that
opportunities  exist  for  attractive   investment   returns.   Such  additional
properties may include some or all of the Berg Land Holdings,  which are subject
to options held by the Company. See "DESCRIPTION OF THE PROPERTIES--Land Holding
and Development  Arrangements." The Company may expand or improve its properties
or, subject to the approval of the Required  Directors,  sell such properties in
whole or in part as determined by the Board. See "FUTURE OPERATIONS--Strategy."

     The Company expects to pursue its investment objectives principally through
the direct  ownership by the Operating Partnerships of the Properties and future
developed  properties.  Future development or investment  activities will not be
limited to any specified  percentage of the  Company's  assets.  The Company may
also  participate  with other  entities in  property  ownership,  through  joint
ventures or other types of  co-ownership.  Equity  investments may be subject to
existing mortgage  financing and other indebtedness which have priority over the
equity interest of the Company.

     While the Company will emphasize equity real estate investments, it may, in
its  discretion and subject to the percentage  ownership  limitations  and gross
income tests necessary for REIT qualification, invest in mortgage and other real
estate interests  including  securities of other real estate investment  trusts.
The Company has not previously invested in mortgages or securities of other real
estate  investment  trusts and does not have any present  intention to make such
investments.

FINANCING POLICIES

   
     The  Company   intends  to  maintain  a  ratio  of  debt  to  Total  Market
Capitalization  of no more than 50%. The Company's ratio of debt to Total Market
Capitalization would have been approximately 42% at September 30, 1998, on a pro
forma  basis  after  giving  effect to the UPREIT  Transactions.  See "PRO FORMA
CAPITALIZATION." The Company, however, may from time to time reevaluate its debt
policy in light of then current economic conditions,  relative costs of debt and
equity capital, the market values of its properties, growth and acquisition
    

                                       -67-
<PAGE>

opportunities  and other  factors.  Subject to the need for more than 75% of the
directors to approve debt  increases  above 50% of Total Market  Capitalization,
the Company may modify its debt policy and may increase or decrease its ratio of
debt to Total Market Capitalization.

     The  Company has  established  its debt  policy  relative  to Total  Market
Capitalization,  because the Company  believes that the book value of its assets
(which to a large extent consists of the depreciated value of real property, the
Company's  primary  tangible  asset) does not accurately  reflect its ability to
borrow  and  to  meet  debt   service   requirements.   However,   Total  Market
Capitalization is more variable than book value and does not necessarily reflect
the fair market value of the Company's  underlying assets.  Although the Company
will  consider  factors  other than market  capitalization  in making  decisions
regarding the  incurrence  of debt (such as the  estimated  market value of such
properties upon  refinancing,  and the ability of particular  properties and the
Company as a whole to generate cash flow to cover expected debt services), there
can be no assurance  that the Company  will  maintain the ratio of debt to Total
Market Capitalization (or to any other measure of asset value) described above.

     To the extent that the board of directors of the Company determines to seek
additional capital, the Company may raise such capital through additional equity
offerings,  debt  financing or retention  of cash flow (after  consideration  of
provisions  of the  Code  requiring  the  distribution  by a REIT  of a  certain
percentage  of its taxable  income and taking into  account  taxes that would be
imposed on  undistributed  taxable  income),  or through a combination  of these
sources.  It is the Company's present  intention that any additional  borrowings
will be made through the Operating Partnerships,  although the Company may incur
borrowings that would be reloaned to the Operating Partnerships.  See "OPERATING
PARTNERSHIP  AGREEMENT." Borrowings may be unsecured or may be secured by any or
all assets of the Company,  the Operating  Partnerships,  or any existing or new
property  and may have full or  limited  recourse  to all or any  portion of the
assets of the  Company,  the  Operating  Partnerships,  or any  existing  or new
property.

   
     The  Company  has not  established  any  limit on the  number  or amount of
mortgages  that may be placed on any single  property or on its  portfolio  as a
whole.  Of the Company's 69 R&D Properties,  currently 18 Properties  secure the
Prudential  Secured Loan and 14  Properties  secure the Wells Fargo Line.  Until
October 1999, the Wells Fargo Line with a remaining balance of approximately $61
million   would  be  available  to  fund  property   acquisitions,   development
activities,  and for general  corporate  purposes.  The Company may determine to
issue securities  senior to the Common Stock,  including shares of new series of
Preferred  Stock and debt  securities  (either of which may be convertible  into
Common Stock or accompanied by warrants to purchase capital stock).  The Company
may also determine to finance acquisitions through the exchange of properties or
the issuance of additional L.P. Units in the Operating  Partnerships,  shares of
Common Stock or other securities.
    

     In the event that the board of  directors  determines  to raise  additional
equity capital,  it has the authority,  without shareholder  approval,  to issue
additional  shares  of  Common  Stock,   Preferred  Stock  other  capital  stock
(including  securities  senior to the Common Stock) of the Company in any manner
(and on such terms and for such  consideration) it deems appropriate,  including
in exchange for property. In the event that the Company issues (whether for cash
or  property)  any shares of Common Stock or  securities  convertible  into,  or
exchangeable  or  exercisable  for,  shares of Common Stock,  subject to certain
limited exceptions, including the issuance of Common Stock pursuant to any stock
incentive plan adopted by the Company or pursuant to Limited Partners'  exercise
of the Exchange  Rights or the Put Rights,  the Limited  Partners  will have the
right to purchase  Common Stock or such  securities  in order to maintain  their
respective percentage interests in the Company and the Operating Partnerships on
a consolidated basis. If the board of directors determines that the Company will
raise   additional   equity  capital  to  fund   investments  by  the  Operating
Partnerships,   the  Company  will   contribute  such  funds  to  the  Operating
Partnerships  as a  contribution  to capital and purchase of additional  general
partnership  interest;  however,  holders  of L.P.  Units will have the right to
participate  in such  funding on a pro rata basis.  In the event that holders of
L.P.  Units sell their L.P.  Units to the Company  pursuant to their Put Rights,
the  Company  is  authorized  to raise the funds for such  purchase  by  issuing
additional shares of Common Stock. In addition, the Company may issue additional
shares of Common Stock in connection  with the exchange of L.P. Units for shares
of Common Stock pursuant to the exercise of the Exchange Rights.

     The  Company's  Board of  Directors  also has the  authority  to cause  the
Operating Partnerships to issue additional L.P. Units in any manner (and on such
terms and for such consideration) as it deems appropriate, including in exchange
for property. In the event that the Operating Partnerships issue new L.P. Units
for cash  (but not  property),  the  Limited  Partners  will  have the  right to
purchase L.P.  Units in order,  and to the extent  necessary,  to maintain their
respective percentage interests in the Operating Partnerships. Any such new L.P.
Units will be

                                    -68-
<PAGE>

exchangeable for Common Stock pursuant to the Exchange Rights or may be tendered
to  the  Company  pursuant  to  the  Put  Rights.  See  "OPERATING   PARTNERSHIP
AGREEMENT--Exchange Rights, Put Rights and Registration Rights."

DISPOSITION POLICY

     The Company has no current  intention to dispose of any of the  Properties,
although it reserves  the right to do so. The tax basis of the Limited  Partners
in the  Properties  in the Operating  Partnerships  is  substantially  less than
current fair market value.  Accordingly,  prior to the disposition of their L.P.
Units  in  the  Operating  Partnerships,  upon  a  disposition  of  any  of  the
Properties,  a disproportionately large share of the gain for federal income tax
purposes  would be allocated to the Limited  Partners.  See "FEDERAL  INCOME TAX
CONSIDERATIONS--Income  Taxation of the Partnership." Consequently, it may be in
the  interests  of the Limited  Partners  that the Company  continue to hold the
Properties in order to defer such taxable gain. In light of this,  the Operating
Partnership  Agreement provides that for a period of ten years after the closing
or until the Protective  Provisions  Expiration Date, if earlier,  Carl Berg and
Clyde Berg may prohibit the Operating  Partnerships from disposing of Properties
which they designate in a taxable  transaction.  Kontrabecki has a similar right
with respect to the  Kontrabecki  Properties  which will lapse before the end of
the ten-year  period,  if his  beneficial  ownership  interest in the  Operating
Partnerships falls below 750,000 L.P.  Units.  The Limited  Partners may seek to
cause the Company to retain the  Properties  even when such action may not be in
the interests of some, or a majority,  of the  shareholders of the Company.  The
approval of the Required  Directors will be required if the Company sells in any
transaction,  or series of  related  transactions  or  aggregate  sales,  all or
substantially all of the assets of the Company.  The consent of the holders of a
majority of the L.P. Units will be required to effect a sale or sales of all, or
substantially  all,  of  the  assets  of  the  Operating  Partnerships.   For  a
description  of certain  tax  consequences  arising  from the  disposition  of a
property controlled by the Company, see "FEDERAL INCOME TAX  CONSIDERATIONS--The
Aspects of The Operating Partnerships."

CONFLICT OF INTEREST POLICIES

     The  Company  has  adopted  certain   policies  and  entered  into  certain
agreements  with the Berg Group  designed to  eliminate  or  minimize  potential
conflicts of interest.  There can be no assurance  that these  policies  will be
successful  in  eliminating  the  influence of such  conflicts.  If they are not
successful,  decisions  affecting  the Company  could be made that might fail to
reflect fully the interests of all shareholders.

     In recognition of these  potential  conflicts of interest,  the Company and
the Berg Group have agreed that any transaction between the Company and Mr. Berg
or other members of the Berg Group must be approved by the Independent Directors
Committee.  The  members  of the Berg  Group  also have  agreed  that all future
transactions  between the Company and their  Affiliates or any other entities in
which they hold 5% or greater ownership interests shall be subject to review and
approval  by  the  Independent   Directors   Committee.   See  "THE  ACQUISITION
AGREEMENT--Conflict of Interest Provisions."

     In addition,  the Berg Group and the Company  have entered into  agreements
concerning  the lease of office space to the Company,  the  acquisition  of Berg
Land  Holdings  and of  Pending  Development  Projects,  and  the use of BBE for
construction and repair work. The exercise of the Company's rights or the waiver
of any  benefits to the Company  under these  agreements  will be subject to the
approval  of  the  Independent  Directors  Committee.  See  "DESCRIPTION  OF THE
PROPERTIES--Land Holding and Development Arrangements" and "FUTURE OPERATIONS OF
THE COMPANY--Operation and Management."

POLICIES WITH RESPECT TO OTHER ACTIVITIES

     The Company has  authority  to offer  shares of its capital  stock or other
securities  and to  repurchase  or otherwise  reacquire  its shares or any other
securities and may engage in such  activities in the future.  The Company has no
outstanding  loans to other  entities or persons,  including  its  officers  and
directors.  The Company may in the future make loans to joint  ventures in which
it participates in order to meet working capital needs.

     The Company has not engaged in trading, underwriting or agency distribution
or sale of  securities  of other  issuers,  nor has the Company  invested in the
securities  of other  issuers  other  than the  Operating  Partnerships  for the
purpose of exercising control, and does not intend to do so. The Company intends
to make  investments  in such a way that it will not be treated as an investment
company under the Investment Company Act of 1940.

                                     -69-
<PAGE>

     At all times,  the Company intends to make  investments in such a manner as
to be consistent with the requirements of the Code for the Company to qualify as
a REIT unless,  because of changing  circumstances or changes in the Code (or in
Treasury Regulations),  directors representing more than 75% of the entire board
of directors determine that it is no longer in the best interests of the Company
to qualify as a REIT.

     THE  FOLLOWING  SUMMARY  OF  THE  ACQUISITION   AGREEMENT,   INCLUDING  THE
DESCRIPTIONS   OF  CERTAIN   PROVISIONS  SET  FORTH   ELSEWHERE  IN  THIS  PROXY
STATEMENT/PROSPECTUS,   IS  QUALIFIED  IN  ITS  ENTIRETY  BY  REFERENCE  TO  THE
ACQUISITION  AGREEMENT,  WHICH  IS  FILED  AS AN  EXHIBIT  TO  THE  REGISTRATION
STATEMENT  OF WHICH THIS  PROXY  STATEMENT/PROSPECTUS  IS A PART.  A COPY OF THE
AGREEMENT  IS  AVAILABLE   FROM  THE  COMPANY  UPON  REQUEST.   SEE   "AVAILABLE
INFORMATION."

GENERAL

     The  parties  to the  Acquisition  Agreement  are MWP,  MWP I, MWP II,  all
members of the Berg Group,  and all of the Kontrabecki  Partnerships,  including
MWP III. Under the terms of the Acquisition Agreement,  as amended as of July 1,
1998,  the parties  have agreed to operate MWP, MWP I, MWP II and MWP III as the
Operating  Partnerships  subject  to  the  terms  of the  Operating  Partnership
Agreement,  the  Operating  Partnerships  acquired the Berg  Properties  and the
Acquired  Properties in the  Partnership  Closing,  and agreed to consummate the
remaining  transactions  comprising the Berg Acquisition  after the shareholders
have approved  Proposals 1, 3, 4 and 5 at the Special  Meeting.  Pursuant to the
Acquisition Agreement,  the Company is entitled to conduct the operations of all
four limited  partnerships in a consolidated manner under the name "Mission West
Properties,  L.P." The Acquisition Agreement was signed by all parties effective
as of May 14, 1998, and amended as of July 1, 1998.

THE CLOSING

   
     At the Partnership  Closing,  the existing  general partners in MWP, MWP I,
MWP II and MWP III resigned,  the Company  acquired its interest as sole general
partner  in  each of the  Operating  Partnerships,  MWP  acquired  certain  Berg
Properties and the Kontrabecki  Properties in exchange for L.P.  Units,  and the
Company and all limited  partners in each of the Operating  Partnerships  signed
and delivered an Operating Partnership Agreement. In addition, MWP III converted
to a Delaware limited partnership as of the date of the Partnership Closing. The
final closing of the transactions contemplated by the Acquisition Agreement will
occur on the last  business day of the month in which the  shareholders  approve
the UPREIT  Transactions at the Special  Meeting.  At such closing,  the parties
will sign and deliver the Operating Partnership  Agreement,  the Exchange Rights
Agreement,  the Berg  Land  Holdings  Option  Agreement,  the  Pending  Projects
Acquisition   Agreement,   and   subject   to   shareholder   approval   of  the
Reincorporation  Merger,  the Merger Agreement.  The Company expects Mr. Berg to
acquire the Fremont Properties and contribute them to MWP at or before the final
closing date.
    

REPRESENTATIONS AND WARRANTIES

     The  Acquisition  Agreement  provides  for  each  of the  parties  to  make
representations and warranties  customary for transactions of this nature, which

COVENANTS

     The Acquisition Agreement includes covenants pertaining to the provision of
timely and accurate  financial  statements as necessary in  connection  with the
Company's   preparation   of  the   Registration   Statement   and  this   Proxy
Statement/Prospectus,  the  continued  conduct  of each  party's  business  with
respect to the Properties in the ordinary course,  and each party's agreement to
take actions  required and reasonably  requested to comply with the terms of the
Acquisition Agreement and consummate the transactions subject to that agreement.
Under the July 1, 1998  amendment to the  Acquisition  Agreement the Company and
all other parties have agreed to use their  respective  ultimate best efforts to
obtain shareholder approval of all UPREIT Transactions.

   
     The Acquisition  Agreement  requires the Company to provide Exchange Rights
to the  Limited  Partners  with  respect  to their  L.P.  Units and to give them
certain  rights to register the shares of Common Stock  acquired under the terms
of the Exchange Rights Agreement. Also, the Company must take steps necessary to
preserve  and list on the AMEX the shares of Common  Stock  issuable in exchange
for L.P. Units under the Exchange Rights Agreement. Furthermore, the Company has
agreed that each of the Limited  Partners may purchase  his, her or its pro rata
share of new equity securities  offered by the Company subsequent to the closing
date.  Each Limited  Partner's  pro rata  share will be determined  based on the
proportion  which the Limited  Partner's number of L.P. Units bears to the total
number of Outstanding  Shares at the time of the Company's  proposed offering of
new  equity  securities.  The  Limited  Partners  will  have 10 days in which to
respond to the Company's offer of such securities.  Thereafter, the Company will
have a period of 60 days to conclude the sale and issuance of the new securities
upon the same terms  offered to the  Limited  Partners.  A Limited  Partner  may
assign  the right of first  refusal to any  assignee  of at least  500,000  L.P.
Units.  The right of first  refusal will  terminate  upon the earlier of May 14,
2003,  or the written  agreement of the Company and holders of a majority of the
L.P. Units.
    

   
     Under  the  Acquisition  Agreement,  the  Company  has  agreed  to  provide
indemnity  to its  officers,  directors,  employees,  agents and  certain  other
parties with respect to claims brought against  indemnified  parties as a result
of his, her or its service to or relationship  with the Company,  whether before
or after  the  closing  of the  UPREIT  Transactions.  This  indemnification  is
consistent with the provisions of the articles of  incorporation  of the Company
and the  Charter.  See "THE  REINCORPORATION  MERGER--Comparison  of  Rights  of
Shareholders."  The  Company  also has  agreed to take the action  necessary  to
effect the  Reincorporation  Merger,  subject  to  shareholder  approval  at the
Special  Meeting,  and to cause Mission  West-Maryland  to adopt the Charter and
bylaws  described  below.  The  members of the Berg Group will have the right to
nominate  for  election  to  the  Board  of  Directors   the  Berg  Group  Board
Representatives so long as the Berg Group and its Affiliates beneficially own an
aggregate of at least 15% of the Fully-Diluted number of shares of Common Stock.
In the event  that their  ownership  falls  below 15% but is at least  10%,  the
members  of the Berg  Group  will  have the right to  nominate  one  person  for
election to the board of directors.  See "CERTAIN PROVISIONS OF MARYLAND LAW AND
MISSION WEST-MARYLAND'S CHARTER AND BYLAWS."
    

CONFLICTS OF INTEREST PROVISIONS

     The Acquisition  Agreement  includes the undertaking of Carl E. Berg not to
directly  or  indirectly  acquire or develop,  or acquire  any equity  ownership
interest in any entity that has an  ownership  interest in any real estate zoned
or  intended  for use as R&D  Properties  or similar  industrial  facilities  or
intends to engage in similar  real  estate  activities  (with the  exception  of
investments in securities of publicly traded companies,  which securities do not
represent more than 10% of the outstanding  voting securities of such companies)
in California,  Oregon or Washington  without first  disclosing  such investment
opportunity to the Company and making such opportunity  available to the Company
subject to the approval of the Independent Directors Committee. This restriction
does not apply to any acquisition, development or investment with respect to the
Berg Land  Holdings  and the  Pending  Development  Projects.  This  restriction
remains in effect until the date on which both of the following  conditions  are
satisfied:  (i) no nominee of the Berg Group is a member of the Company's  board
of directors and (ii) the Berg Group and its Affiliates  (other than the Company
and  the  Operating  Partnerships)   beneficially  own  less  than  25%  of  the
outstanding  Common Stock of the Company  (including for these  purposes  shares
issuable upon exercise of the Exchange  Rights subject to the Ownership  Limit).
In  addition,  transactions  between the Company and any Berg Group  member,  or
entity in which a Berg Group  member  holds at least 5% of the equity  interests
are subject to review and approval by the Independent Directors Committee. Aside
from  those  restrictions,  Mr.  Berg and other  members  of the Berg Group will
generally  have freedom of action with respect to the conduct of their  business
activities  and will not be required to seek the approval of such  activities or
refer  business  opportunities  to the  Company,  nor will  they be  subject  to
liability for failure to do so.

TERMINATION

     The Acquisition Agreement is terminable prior to the final closing date for
the Berg Acquisition only by the Company or Mr. Berg in the event there exists a
non-appealable  final order, decree or judgment preventing the occurrence of any
aspect of the UPREIT Transactions.

SURVIVAL AND INDEMNIFICATION MATTERS

     All  representations  and  warranties  of the  parties  to the  Acquisition
Agreement  will survive the closing for a period of one year.  Each party to the
Acquisition  Agreement is obligated  to  indemnify  the other  parties and their
Affiliates with respect to losses and liability  resulting from  inaccuracies in
the representations and warranties of such party,  failure by a party to perform
its obligations under the Acquisition Agreement,  failure to satisfy liabilities
not  assumed by the  Operating Partnerships  or the  Company,  and any claim for
brokers' commissions or finder's fees.

                         OPERATING PARTNERSHIP AGREEMENT

     THE FOLLOWING SUMMARY OF THE OPERATING PARTNERSHIP AGREEMENT, INCLUDING THE
DESCRIPTIONS   OF  CERTAIN   PROVISIONS  SET  FORTH   ELSEWHERE  IN  THIS  PROXY
STATEMENT/PROSPECTUS, IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE OPERATING
PARTNERSHIP  AGREEMENT,  WHICH  IS  FILED  AS AN  EXHIBIT  TO  THE  REGISTRATION
STATEMENT OF WHICH THIS PROXY STATEMENT/PROSPECTUS IS A PART.

MANAGEMENT

     As of the Partnership  Closing  effective date, the Operating  Partnerships
consists of four separate Delaware limited  partnerships engaged in the combined
operation  and  ownership  of  the  Properties  pursuant  to  the  terms  of the
Acquisition  Agreement,  as amended,  and the Operating  Partnership  Agreement,
which  is  identical  in all  material  respects  for all  four  of the  limited
partnerships.  Generally,  pursuant to the Operating Partnership Agreement,  the
Company as the sole general partner of the Operating  Partnerships has exclusive
control of the business and assets of the  Operating  Partnerships  and has full
and  complete  authority,  discretion  and  responsibility  with  respect to the
Operating  Partnerships'   operations  and  transactions,   including,   without
limitation,  acquisitions of additional properties, borrowing funds, raising new
capital,  leasing buildings,  as well as selecting and supervising all employees
and agents of the  Operating  Partnerships.  Through its authority to manage the
business and affairs of the Company,  the board of directors of the Company will
direct the business of the Operating Partnerships.  The Berg Group has the right
to nominate  two  individuals  for election to the board of directors so long as
the members of the Berg Group and their  Affiliates  (other than the Company and
the Operating  Partnerships)  beneficially  own in the aggregate at least 15% of
the outstanding shares of Common Stock on a Fully-Diluted  basis. If the members
of the Berg Group and such Affiliates  beneficially own, in the aggregate,  less
than 15% but at least 10% of the Common Stock,  on a  Fully-Diluted  basis,  the
Berg Group will have the right to nominate  one  individual  for election to the
board of directors.

     Notwithstanding   the   Company's   effective   control  of  the  Operating
Partnerships,  the consent of the Limited Partners holding an L.P. Unit Majority
is  required  with  respect  to  certain  extraordinary  actions  involving  the
Operating Partnerships including (i) the amendment,  modification or termination
of the  Operating  Partnership  Agreement,  (ii) a  general  assignment  for the
benefit of creditors or the appointment of a custodian,  receiver or trustee for
any of the assets of the Operating  Partnerships,  (iii) the  institution of any
proceeding  for bankruptcy of the Operating  Partnerships,  (iv) the transfer of
any general partnership interests in the Operating Partnerships, including (with
certain  exceptions)  transfers  attendant  to  any  merger,   consolidation  or
liquidation  of the Company,  (v) the admission of any  additional or substitute
general partner in the Operating  Partnerships;  and (vi) a Change of Control of
the  Operating  Partnerships.  In  addition,  until  the  Protective  Provisions
Expiration  Date,  the consent of the  Limited  Partners  holding the L.P.  Unit
Majority is also required with respect to (i) the  liquidation  of the Operating
Partnerships, (ii) the sale or other transfer of all or substantially all of the
assets  of  the  Operating   Partnerships   and  certain  mergers  and  business
combinations  resulting in the complete disposition of all L.P. Units; and (iii)
the  issuance  of  limited   partnership   interests   having  seniority  as  to
distributions, assets and voting over the L.P. Units.

     Carl Berg and Clyde  Berg have the right for a period of ten  years,  or if
sooner,  until the Protective  Provisions  Expiration  Date, to prohibit taxable
transfers of designated  Properties by the Operating  Partnerships without their
prior written  consent.  John Kontrabecki has similar rights with respect to the
former  Kontrabecki  Properties,  which  expire after he owns fewer than 750,000
L.P. Units. The Operating  Partnerships  will be able to effect  "tax-free" like
kind  exchanges  under  Section 1031 of the Code,  or in  connection  with other
non-taxable  transactions,   such  as  a  contribution  of  property  to  a  new
partnership,  without obtaining the prior written consent of these  individuals.
See "POLICIES WITH RESPECT TO CERTAIN ACTIVITIES Disposition Policy."

TRANSFERABILITY OF L.P. UNITS

     The Operating  Partnership Agreement provides that the Limited Partners may
transfer  their L.P.  Units subject to certain  limitations.  Except for certain
transfers  by the  Limited  Partners  to or from  certain  of their  affiliates,
however,  all transfers  may be made only with the prior written  consent of the
Company as the sole general partner of the Operating Partnerships.

     In addition,  no transfer of L.P. Units by the Limited Partners may be made
in  violation  of certain  regulatory  and other  restrictions  set forth in the
Operating Partnership Agreement. Except in the case of certain permitted

                                    -74-
<PAGE>

transfers to or from certain  Affiliates of the Limited  Partners,  the Exchange
Rights,  the Put  Rights,  the New Equity  Financing  Rights and the  Protective
Provisions  will no longer be applicable to L.P. Units so  transferred,  and the
transferee  will  not  have any  rights  to  nominate  persons  to the  board of
directors of the Company.

ADDITIONAL CAPITAL CONTRIBUTIONS AND LOANS

     The  Operating   Partnership  Agreement  provides  that  if  the  Operating
Partnerships requires additional funds to pursue its investment objectives,  the
Company  may fund such  investments  by raising  additional  equity  capital and
making a capital contribution to the Operating Partnerships or by borrowing such
funds and lending the net proceeds thereof to the Operating Partnerships. If the
Company  intends to provide  additional  funds through a contribution to capital
and purchase of units of general partnership interest, the Limited Partners will
have the right to  participate  in such funding on a pro rata,  pari passu basis
and to acquire additional L.P. Units (the "New Equity Financing Rights"). If the
Limited Partners do not participate in such financing,  the Company will acquire
additional units of general partnership  interest. In either case, the number of
additional units of partnership interest will be increased based upon the amount
of  the  additional  capital  contributions  and  the  value  of  the  Operating
Partnerships as of the date such contributions are made.

   
     In addition, as general partner of the Operating Partnerships,  the Company
has the ability to cause the Operating  Partnerships  to issue  additional  L.P.
Units.  In the event that the Operating  Partnerships  issue new L.P. Units (for
cash but not property), the Limited Partners will have the right to purchase new
L.P. Units at the price offered by the Company in the transaction giving rise to
such  participation  right in order,  and to the extent  necessary,  to maintain
their  respective  percentage  interests  in  the  Operating  Partnerships.  See
"POLICIES WITH RESPECT TO CERTAIN ACTIVITIES-- Financing."
    

EXCHANGE RIGHTS, PUT RIGHTS AND REGISTRATION RIGHTS

   
     Subject to  shareholder  approval of Proposal 5, the Limited  Partners will
have the  Exchange  Rights,  which  generally  become  exercisable  on the first
anniversary  of the final closing date for the Berg  Acquisition.  However,  the
Limited Partners may, in the aggregate,  tender L.P. Units for exchange prior to
the first anniversary  solely in connection with (i) the registration of 500,000
shares of Common Stock acquired upon exercise of the Exchange  Rights for resale
on a Form S-3 (or any equivalent form) and (ii) a registered  public offering of
Common  Stock  initiated by the Company to the extent of 25% of the total shares
in the  offering  subject  to the  underwriters'  unlimited  right to reduce the
participation of all selling  shareholders.  In addition,  once in each 12-month
period  beginning  on the  first  anniversary  of the date the  Exchange  Rights
Agreement is signed and delivered by the parties,  the Limited  Partners  (other
than Carl Berg and Clyde  Berg)  will have the right to  exchange  a portion  of
their L.P. Units for shares of Common Stock (subject to the Ownership Limit) and
to  exercise  the Put  Rights  to sell a  portion  of  their  L.P.  Units to the
Operating  Partnerships  at a price  equal to the  average  Market  Price of the
Common Stock for the  10-trading  day period  immediately  preceding the date of
tender (the "Tender  Price").  Upon any exercise of the Put Rights,  the Company
will have the  opportunity for a period of 15 days to elect to fund the purchase
of the L.P.  Units and  purchase  additional  general  partner  interests in the
Operating Partnerships for cash, unless the purchase price exceeds $1 million in
the aggregate for all tendering Limited  Partners,  in which case, the Operating
Partnerships  or the  Company  shall be entitled  to reduce  proportionally  the
number of L.P. Units to be acquired from each tendering  Limited Partner so that
the total purchase price is not more than $1 million.

     The Exchange  Rights  Agreement will permit every Limited Partner to tender
L.P.  Units to the Company,  and at the  Company's  election,  to receive  cash,
Common Stock, or a combination of cash and Common Stock in exchange for the L.P.
Units  tendered,  subject to the Ownership  Limit,  or the Berg Group  Ownership
Limit,  as the case may be.  Pursuant  to the  Exchange  Rights  Agreement,  the
holders  of L.P.  Units  will have the right to  participate  in any  registered
public  offering of the Common  Stock  initiated by the Company to the extent of
25% of the total  shares sold in the  offering  upon  converting  L.P.  Units to
shares of Common  Stock,  but subject to the  underwriters'  unlimited  right to
reduce the participation of all selling shareholders.  The holders of L.P. Units
will be able to request resale  registrations of shares of Common Stock acquired
on exchange of L.P. Units on a Form S-3, or any equivalent  form of registration
statement,  and  after  the  first  year  following  the  closing  of  the  Berg
Acquisition,  the  Company  will be  obligated  to  effect no more than two such
registrations  in any  12-month  period.  The Company is obligated to assist the
L.P. Unit holders in obtaining a firm commitment underwriting agreement for such
resale from a qualified investment banking firm. If registration on Form S-3, or
an  equivalent  form,  is not  available  for any reason,  the  Company  will be
obligated to effect a  registration  of the shares to be acquired on exercise of
the Exchange  Rights on Form S-11,  or an equivalent  form,  in an  underwritten
public offering, upon demand by the holders of no fewer than 500,000 L.P. Units.
All holders of L.P. Units will be entitled to participate
    

                                    -75-
<PAGE>

in such  registration.  The  Company  will bear all costs of such  registrations
other than selling expenses,  including  commissions and separate counsels' fees
of the L.P.  Unit  holders.  The  Company  will not be  required  to effect  any
registration  for resale on Form S-3, or equivalent  form of Common Stock shares
issuable  to the holder of L.P.  Units if the  request is for less than  250,000
shares.

OTHER MATTERS

     The   Operating   Partnership   Agreement   requires   that  the  Operating
Partnerships be operated in a manner that will enable the Company to satisfy the
requirements  for being  classified as a REIT and to avoid any federal income or
excise tax liability.

     The Operating  Partnership  Agreement  provides that the net operating cash
flow  of the  Operating Partnerships,  as  well  as net  sales  and  refinancing
proceeds,  will be  distributed  from time to time as determined by the board of
directors of the Company (but not less  frequently  than  quarterly) pro rata in
accordance   with  the   partners'   percentage   interests  in  the   Operating
Partnerships. See "Distribution Policy."

     Pursuant to the Operating Partnership Agreement, the Operating Partnerships
will also  assume and pay when due,  or  reimburse  the  Company for payment of,
certain  costs  and  expenses  relating  to  the  continuity  of  existence  and
operations  of the Company.  In addition,  the Operating  Partnership  Agreement
obligates the Operating Partnerships  to reimburse  all  organization  costs and
expenses of the UPREIT Transactions paid or incurred by the Berg Group.

     The Operating  Partnership  Agreement provides that upon the exercise of an
outstanding  option  under the  Company's  1997  Option  Plan,  the  Company may
purchase  additional  general partner interests in the Operating Partnerships by
contributing the exercise proceeds to the Operating Partnerships.  The increased
interest of the Company shall be equal to the percentage of  Outstanding  Shares
represented by the shares acquired upon exercise of the option.

TERM

     The  Operating Partnerships  will  continue in full force and effect  until
December  31,  2048 or  until  sooner  dissolved  pursuant  to the  terms of the
Operating Partnership Agreement.

NUMBER, TERMS AND ELECTION OF DIRECTORS

     Following  the  Reincorporation   Merger,  the  number  of  directors  will
initially be set at five. However, the bylaws of Mission  West-Maryland  provide
that the number of  directors  may be changed  from time to time by the board of
directors, provided that the number will never be less than the minimum required
by Maryland law or more than 15. The board of directors  may determine the exact

     COMPENSATION   COMMITTEE.   The  Company  has  established  a  Compensation
Committee to determine  compensation for the Company's executive officers and to
implement  the  Company's  1997 Stock Option Plan.  The  Compensation  Committee
currently consists of two Independent Directors and will not include any officer
of the Company.

     INDEPENDENT   DIRECTORS  COMMITTEE.   Following  the  consummation  of  the
transactions  contemplated  herein,  the Board of Directors  will  establish the
Independent Directors Committee consisting of at least two Independent Directors
to approve  transactions  between  the Company and members of the Berg Group and
their affiliates and any entity in which any of them directly or indirectly owns
at least 5% of the equity  interests.  In addition,  the  Independent  Directors
Committee will determine whether to exercise the Company's rights under the Berg
Land Holdings Option Agreement.

COMPENSATION OF DIRECTORS

     The  Company  intends  to pay its  directors  who are not  officers  of the
Company fees for their  services as  directors.  Directors  will receive  annual
compensation  of $15,000,  plus a fee of $1,000 for  attendance (in person or by
telephone)  at each  meeting of the board of  directors,  but not for  committee
meetings.  Officers of the Company who are also  directors  will not be paid any
director fees.

     Each member of the Board of Directors who is not an employee of the Company
or any of its  subsidiaries  or affiliates (a  "Non-Employee  Director") and who
becomes a member of the Board of Directors  after November 10, 1997, the date on
which  the 1997  Stock  Option  Plan was  approved  by the  shareholders  of the
Company,  will  automatically  receive a grant of an option to  purchase  50,000
shares of Common  Stock at an  exercise  price  equal to 100% of the fair market
value of the Common  Stock at the date of grant of such option upon  joining the
Board of  Directors.  Such options  will become  exercisable  cumulatively  with
respect  to 1/48th  of the  underlying  shares  on the  first day of each  month
following the date of grant. Generally,  the options must be exercised while the
optionee is a director of the Company.

EXECUTIVE COMPENSATION

     Upon the  acquisition of control of the Company by the Berg Voting Group on
September  2, 1997 all former  officers  and  directors  resigned as of the same
date. The officers and directors  appointed to replace them,  including Mr. Berg
and Mr. Kirk, received no compensation  during the 1997 fiscal year.  Therefore,
no officer or director  who received  compensation  during the fiscal year ended
December  31,  1997 will  receive  compensation  during the fiscal  year  ending
December 31, 1998. The following  table sets forth the annual base salary of the
former  chief  executive  officer and the annual  base salary  which the Company
expects to pay in 1998 to the  Company's  president  and four other most  highly
compensated  executive  officers  whose  annualized  base  salary is expected to
exceed $100,000  (collectively,  the "Named  Executives").  The Company also may
pay,  subject to approval of the board of directors,  a cash bonus to each Named
Executive in an amount not to exceed such executive's base salary.

     Group  Ltd.  (of which Mr.  Earley  was  concurrently  the Chief  Executive
     Officer and President) in the total amount of $75,390  ($49,640 paid to the

BENEFIT PLANS

     1997 STOCK OPTION PLAN.  The Company's  1997 Stock Option Plan (the "Option
Plan") was approved by the  Company's  shareholders  on November  10, 1997.  The
Option  Plan was  adopted so that the  Company  may  attract and retain the high
quality  employees,  consultants and directors  necessary to build the Company's
infrastructure and to provide ongoing  incentives to the Company's  employees in
the form of options to purchase the  Company's  Common Stock by enabling them to
participate in the Company's  success.  The following summary is qualified in it
entirety by  reference  to the full text of the Option Plan, a copy of which was
filed as an exhibit to the Company's  Proxy  Statement,  dated October 20, 1997,
filed with the Commission on October 20, 1997.

     The Option Plan provides for the granting to employees  (including officers
and directors who are employees) of "incentive stock options" within the meaning
of Section  422 of the Code,  and for the  granting of  nonstatutory  options to
employees,  consultants  and  directors,  including  directors  who are  neither
employees  of, nor  consultants  to,  the  Company  ("Non-Employee  Directors").
Options to purchase a maximum of 5,500,000 shares of Common Stock may be granted
under the Option  Plan,  subject to  equitable  adjustments  to reflect  certain
corporate  events.  The Option  Plan will be  administered  by the  Compensation
Committee.  The  interpretation  and construction of any provision of the Option
Plan  is  within  the  sole  discretion  of the  Compensation  Committee,  whose
determination is final and conclusive. Members of the Board or committee receive
no  additional   compensation   for  their  services  in  connection   with  the
administration of the Option Plan.

     The Compensation  Committee selects the optionees and determines the number
of shares to be  subject to each  option  and the time or times at which  shares
become exercisable under the option,  except for options granted to Non-Employee
Directors pursuant to automatic grants.

     Each option  granted  under the Option Plan is evidenced by a written stock
option agreement between the Company and the optionee.  The Option Plan provides
that options must vest and,  unless  otherwise  decided by the Committee  become
exercisable  cumulatively as to 20% of the underlying shares on each anniversary
of the date of grant for so long as the  optionee is  employed  by or  providing
service to the Company.

     The price per share exercise price of options granted under the Option Plan
may not be less than 100% of the fair market value on the date of grant,  except
in certain specific  circumstances,  in which case the exercise price may not be
less than 110%.  Each  option  may be  exercised  only to the extent  that it is
vested.  Options must generally be exercised during the optionee's employment or
within 30 days  following the  optionee's  termination of status as an employee,
consultant or director,  unless termination is due to the death or disability of
an  optionee.  If  termination  of status is due to death or  disability  of the
optionee, an option may be exercised within six months.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

     During  the  last  completed   fiscal  year,  no  current  members  of  the
Compensation  Committee were officers of the Company.  The current  officers and
directors of the Company were  elected or  appointed  during the current  fiscal
year,  except for Carl E. Berg.  Mr.  Berg  became an officer  and  director  in
September 1997, but did not serve on the Compensation  Committee during the last
completed  fiscal  year.  No  officer  who  received  compensation  in the  last
completed  fiscal year is now an officer.  The current  members of the Company's
Compensation  Committee were elected by the board of directors  effective during
the current fiscal year and are not officers or employees of the Company.

LIMITATION OF LIABILITY AND INDEMNIFICATION

     The MGCL  permits  a  Maryland  corporation  to  include  in its  charter a
provision   limiting  the  liability  of  its  directors  and  officers  to  the
corporation  and  its  stockholders  for  money  damages  except  for  liability
resulting  from (a) actual  receipt of an  improper  benefit or profit in money,
property or services; or (b) active and deliberate  dishonesty  established by a
final  judgment as being material to the cause of action.  The Charter  contains
such a provision which eliminates such liability to the maximum extent permitted
by the MGCL.

     The Charter also  authorizes  Mission  West-Maryland  to the maximum extent
permitted  by  Maryland  law,  to  obligate  itself to  indemnify  and to pay or
reimburse reasonable expenses in advance of final disposition of a proceeding to
any present or former  director  or  officer,  or any  individual  who,  while a
director of Mission

                                    -80-
<PAGE>

West-Maryland and at the request of Mission West-Maryland,  serves or has served
another corporation,  real estate investment trust, partnership,  joint venture,
trust,  employee  benefit plan or any other  enterprise as a director,  officer,
partner  or  trustee  of  such   corporation,   real  estate  investment  trust,
partnership,  joint venture,  trust,  employee  benefit plan or other enterprise
from and against any claim or liability to which such person may become  subject
or which  such  person  may incur by reason of his status as a present or former
director  or officer of Mission  West-Maryland.  The  Maryland  Bylaws  obligate
Mission  West-Maryland,  to the maximum  extent  permitted  by Maryland  law, to
indemnify  and to pay or  reimburse  reasonable  expenses  in  advance  of final
disposition of a proceeding to (i) any present or former director or officer who
is made a party to the  proceeding  by reason of his service in that capacity or
(ii) any individual  who, while a director of Mission  West-Maryland  and at the
request of Mission West-Maryland, serves or has served another corporation, real
estate investment trust,  partnership,  joint venture,  trust,  employee benefit
plan or any other enterprise as a director,  officer, partner or trustee of such
corporation,  real estate investment trust,  partnership,  joint venture, trust,
employee  benefit  plan or  other  enterprise  and  who is  made a party  to the
proceeding  by reason of his  service in that  capacity.  The Charter and bylaws
also permit  Mission  West-Maryland  to  indemnify  and advance  expenses to any
person  who  served  a  predecessor  of  Mission  West-Maryland  in  any  of the
capacities described above and any employee or agent of Mission West-Maryland or
a predecessor of Mission West-Marylad.

     The MGCL requires a  corporation  (unless its charter  provides  otherwise,
which the  Charter  does not) to  indemnify  a director  or officer who has been
successful,  on the merits or  otherwise,  in the defense of any  proceeding  to
which he is made a party by reason of his  service  in that  capacity.  The MGCL
permits a  corporation  to  indemnify  its  present  and  former  directors  and
officers,  among others, against judgments,  penalties,  fines,  settlements and
reasonable  expenses actually incurred by them in connection with any proceeding
to which  they may be made a party by reason of their  service in those or other
capacities unless it is established that (a) the act or omission of the director
or officer was material to the matter giving rise to the  proceeding and (i) was
committed  in bad  faith  or (ii)  was  the  result  of  active  and  deliberate
dishonesty,  (b) the director or officer actually  received an improper personal
benefit  in  money,  property  or  services  or (c) in the case of any  criminal
proceeding, the director or officer had reasonable cause to believe that the act
or omission was unlawful.  However,  under the MGCL, a Maryland  corporation may
not  indemnify  for an  adverse  judgment  in a suit by or in the  right  of the
corporation  or for a judgment of liability on the basis that  personal  benefit
was improperly  received,  unless in either case a court orders  indemnification
and then only for  expenses.  In  addition,  the MGCL permits a  corporation  to
advance  reasonable  expenses  to a director or officer  upon the  corporation's
receipt  of (a) a written  affirmation  by the  director  or officer of his good
faith   belief  that  he  has  met  the  standard  of  conduct   necessary   for
indemnification  by the corporation  and (b) a written  undertaking by him or on
his behalf to repay the amount paid or reimbursed by the corporation if it shall
ultimately be determined that the standard of conduct was not met.

                              CERTAIN TRANSACTIONS

PRIVATE PLACEMENT TRANSACTIONS--1997

     In  September  and  November of 1997,  the Company sold Common Stock in two
private placement  transactions.  On September 2, 1997, the Company sold 200,000
shares  of  Common  Stock at $4.50  per share  prior to the  Reverse  Split.  In
connection with that  transaction  the Company  received an opinion from Slusser
Associates,  Inc. that the  transaction  was fair to the Company's  shareholders
from a  financial  point of view.  Slusser  Associates,  Inc.  received a fee of
$150,000.  On November 12, 1997,  the Company  sold  1,250,000  shares of Common
Stock at $4.50 per share after  giving  effect to the Reverse  Split.  The price
paid for the Common Stock in the November  transaction was the same as the price
paid in the  September  private  placement,  and the  Company  did not  retain a
financial advisor to render a fairness  opinion.  There can be no assurance that
the terms of the November private  placement were as favorable to the Company as
would have been obtained with unrelated third parties.  The purchasers of record
of the  Common  Stock  in the  two  transactions  included,  among  others,  the
following 5% shareholders,  executive officers,  directors, and affiliates of 5%
shareholders, executive officers and directors:

Stock in connection with the November Private Placement.

     In connection with the September and November private  placements,  certain
purchasers of Common Stock,  including Mr. Aalgaard,  Mr. Warden, Mr. Bolger and
the  Yoergs  entered  into  the  Voting  Rights  Agreement.  The  Voting  Rights
Agreements  terminate at the earliest of the following  dates: (i) upon any sale
of the purchaser's  shares of Common Stock pursuant to a registration  statement
declared  effective  under the  Securities  Act, but only as to the  purchaser's
shares of Common Stock so sold; (ii) upon the sale of the purchaser's  shares of
Common Stock pursuant to Rule 144 promulgated under the Securities Act, but only
as to the  purchaser's  shares of Common Stock so sold; or (iii) two years after

purchasers  to sell and issue  6,495,058  shares of Common  Stock in the Private
Placement,   the  terms  of  which  are   described   elsewhere  in  this  Proxy
Statement/Prospectus.       See       "BACKGROUND       OF      THE       UPREIT

(1)  Beneficial  ownership is  determined  in  accordance  with the rules of the
     Securities and Exchange  Commission  which generally  attribute  beneficial
     ownership of  securities to persons who possess sole or shared voting power
     and/or  investment  power with  respect to those  securities  and  includes
     securities which such person has the right to acquire beneficial  ownership
     within 60 days of October 15, 1998. Unless otherwise indicated, the persons
     or entities  identified in this table have sole voting and investment power
     with respect to all shares shown as beneficially owned by them.  Percentage
     ownership  calculations  are based on 1,698,536  shares  outstanding  as of
     October 15, 1998.  "Number of Outstanding Shares Owned" reflects the number
     of shares  of  Common  Stock  and the  number  of L.P.  Units  which may be
     exchanged  for  Common  Stock   following  the  completion  of  the  UPREIT
     Transactions,  whether  or not the  beneficial  owner  of such  Outstanding
     Shares has the right to acquire  common  stock  upon the  exchange  of L.P.
     Units  within  60 days.  Percentage  Ownership  calculations  are  based on

                           THE REINCORPORATION MERGER

INTRODUCTION

     The Company's  board of directors  believes that the best  interests of the
Company  and  its  shareholders   will  be  served  by  changing  the  state  of
incorporation  of the  Company  from  California  to  Maryland  by  means of the
Reincorporation  Merger. The principal reason for the Reincorporation  Merger is
that the MGCL contains  provisions  conducive to the  operation of a REIT.  Many
REITs have  incorporated  in the State of  Maryland,  and the board of directors
believes that this has provided state  regulatory  authorities and courts with a
defined body of administrative and case law concerning the governance of REITs.

     The  Reincorporation  Merger will be  effected by merging the Company  into
Mission  West-Maryland,  a newly formed wholly-owned  subsidiary of the Company,
which was incorporated for the purpose of redomiciling the Company as a Maryland
corporation  and  acquiring,  recapitalizing  and  continuing  the  business and
operations of the Company.  Upon completion of the  Reincorporation  Merger, the
Company will cease to exist and Mission  West-Maryland  will continue to operate
the business of the Company under the name Mission West Properties, Inc.

EXCHANGE OF SECURITIES

     Pursuant  to  the  Agreement   and  Plan  of  Merger,   which  will  be  in
substantially  the form attached  hereto as Exhibit A (the "Merger  Agreement"),
each outstanding share of Common Stock will  automatically be converted into one
share of New Common Stock at the  effective  time of the merger and  outstanding
options and warrants  for the  purchase of Common  Stock will be  exchanged  for
options and warrants for the purchase of the equivalent  number of shares of New
Common Stock. Each stock certificate  representing issued and outstanding shares
of Common  Stock will  continue  to  represent  the same number of shares of New
Common  Stock.  Options and warrants  issued and  outstanding  will  continue to
represent  the right to purchase the same number of shares of New Common  Stock.
IT  WILL  NOT BE  NECESSARY  FOR  SECURITYHOLDERS  TO  EXCHANGE  THEIR  EXISTING
SECURITIES  FOR  SECURITIES  OF MISSION  WEST-MARYLAND.  Securityholders  of the
Company may exchange  their  securities if they so choose,  however.  The Common
Stock  is  listed  for  trading  on  the  AMEX  and  the  PCX,   and  after  the
Reincorporation  Merger,  the New Common Stock will continue to be listed on the
AMEX and the PCX without interruption under the same symbol ("MSW").

APPROVAL AND EFFECTIVENESS OF MERGER

     Under California law, the affirmative vote of a majority of the outstanding
shares of Common  Stock of the  Company is required  for  approval of the Merger
Agreement and the other terms of the  Reincorporation  Merger.  See "THE SPECIAL
MEETING - Votes Required." The  Reincorporation  Merger has been approved by the
Company's board of directors,  which  unanimously  recommends a vote in favor of
the proposal. If approved by the shareholders, it is anticipated that the merger
will  become  effective  as soon  as  practicable  following  the  Meeting  (the
"Effective Date"). However,  pursuant to the Merger Agreement, the merger may be
abandoned  or the Merger  Agreement  may be  amended  by the board of  directors
(except  that  the  principal  terms  may  not be  amended  without  shareholder
approval)  either  before or after  shareholder  approval has been  obtained and
prior to the Effective Date of the Reincorporation  Merger if, in the opinion of
the board of directors of either company,  circumstances arise which make either
action advisable.

     Shareholders of the Company will not have  dissenters'  rights of appraisal
with respect to the Reincorporation Merger.

     The discussion set forth below is qualified in its entirety by reference to
the Merger Agreement,  the Charter and the bylaws of Mission  West-Maryland (the
"Maryland Bylaws" for purposes of this discussion),  which will be substantially
in the forms attached to this Proxy Statement/Prospectus as Exhibits A, B and C,
respectively.

     APPROVAL BY  SHAREHOLDERS  OF THE  REINCORPORATION  MERGER WILL  CONSTITUTE
APPROVAL OF THE MERGER AGREEMENT, THE CHARTER AND THE MARYLAND BYLAWS OF MISSION
WEST-MARYLAND, WHICH WILL BE SUBSTANTIALLY IN THE FORMS SET FORTH AS EXHIBITS A,
B AND C TO THIS PROXY STATEMENT/PROSPECTUS.

POSSIBLE DISADVANTAGES

     Despite  the  unanimous   belief  of  the  board  of  directors   that  the
Reincorporation  Merger  is in  the  best  interests  of  the  Company  and  its
shareholders,  it should be noted that  California  and  Maryland  law differ in
certain respects.  Maryland law may not afford stockholders the same substantive
rights as  California  law. For a  comparison  of  shareholders'  rights and the
powers of management  under Maryland and California  law, see  "--Comparison  of
Rights of Shareholders of the Company and Stockholders Mission West-Maryland."

NO CHANGE IN THE NAME, BUSINESS, MANAGEMENT, LOCATION OF PRINCIPAL OFFICE OR
EMPLOYEE PLANS OF THE COMPANY

     The  Reincorporation  Merger will effect a change in the legal  domicile of
the Company and other changes of a legal nature,  certain of which are described
in this Proxy  Statement/Prospectus.  The Reincorporation Merger will not result
in a change in the name of the Company, except to include "Inc." at the end. The
business,  management, fiscal year, location of the principal office, assets and
liabilities  of the Company  will not change as a result of the  Reincorporation
Merger, although the business, management assets and liabilities may change as a
result of certain other proposals  contained in the Proxy  Statement/Prospectus.
See "BACKGROUND OF THE BERG ACQUISITION," "THE BUSINESS OF BERG & BERG," "FUTURE
OPERATIONS OF COMPANY," AND "MANAGEMENT OF THE COMPANY UPON  CONSUMMATION OF THE
BERG  ACQUISITION."  The  individuals  listed  "MANAGEMENT  OF THE COMPANY  UPON
CONSUMMATION  OF THE BERG  ACQUISITION  will  become  the  directors  of Mission
West-Maryland. In addition, the Company expects to add one or two individuals to
the board of  directors  before the end of 1998.  All  employee  benefit,  stock
option and stock  purchase  plans of the Company  will be  continued  by Mission
West-Maryland,  and each option or right  issued  pursuant to any such plan will
automatically  be converted  into an option or right to purchase the same number
of shares of New Common Stock, at the same price per share, upon the same terms,
and  subject to the same  conditions,  as set forth in such  plan.  Shareholders
should note that  approval of the  Reincorporation  Merger will also  constitute
approval of the assumption of these plans by Mission West-Maryland.

COMPARISON OF RIGHTS OF SHAREHOLDERS OF THE COMPANY AND STOCKHOLDERS OF MISSION
WEST-MARYLAND

     The Company is  organized as a  corporation  under the laws of the State of
California  and Mission  West-Maryland  is organized as a corporation  under the
laws of the State of  Maryland.  As a  California  corporation,  the  Company is
subject  to the  California  General  Corporation  Law (the  "CGCL"),  a general
corporation statute dealing with a wide variety of matters,  including election,
tenure,  duties and  liabilities of directors and officers;  dividends and other
distributions;  rights  of  shareholders;  and  extraordinary  actions,  such as
amendments  to  the  articles  of  incorporation,   mergers,  sales  of  all  or
substantially  all of the Company's assets and dissolution.  The Company also is
governed by its Articles of Incorporation  (the  "California  Articles") and its
Bylaws (the "California Bylaws"),  which have been adopted pursuant to the CGCL.
As a Maryland  corporation,  Mission  West-Maryland  is governed by the Maryland
General  Corporation Law (the "MGCL"),  a general  corporation  statute covering
substantially  the same  matters as are covered by the CGCL,  and by the Charter
and Maryland Bylaws

     The  material  differences  between  the CGCL and the MGCL and among  these
various documents are summarized  below. The CGCL refers to  "shareholders"  and
the MGCL refers to "stockholders."  The use of either term refers to the holders
of stock of the Company or Mission West-Maryland, as the case may be.

     The comparison of certain rights of the shareholders of the Company and the
stockholders  of Mission  West-Maryland  set forth  below does not purport to be
complete  and is subject to and  qualified  in its  entirety by reference to the
CGCL and the MGCL and also to the California  Articles,  the California  Bylaws,
the Charter and the  Maryland  Bylaws,  copies of which are  available  from the
Company as described under "AVAILABLE INFORMATION".

                               CALIFORNIA

                        SHAREHOLDER VOTING RIGHTS

     California law provides for cumulative  voting in the election of directors
(which  permits  holders of less than a majority of the voting  securities  of a
corporation to cumulate their votes and elect a director or directors in certain
situations)  but  permits  the  elimination  thereof  in the  case  of a  listed
corporation  (which is defined as a  corporation  that has shares  listed on the
AMEX or other national securities exchanges). The California Bylaws specifically
provide for cumulative voting.

With  certain  exceptions,  the CGCL  requires  that  mergers,  reorganizations,
dissolution, certain sales of assets and similar transactions be approved by the
holders of a majority of each class of shares outstanding.

Under  the  CGCL,  the  articles  of   incorporation   and  bylaws  may  include
supermajority  voting  provisions.  These provisions,  however,  must be renewed
every  two years and may not  require  a vote in  excess  of  two-thirds  of the
outstanding shares.

                                MARYLAND

                         SHAREHOLDER VOTING RIGHTS

Under the MGCL,  cumulative  voting is not  available  unless so provided in the
corporation's  charter. The Charter does not provide for cumulative voting. As a
result,  holders of a majority of the shares of Maryland  Common Stock generally
would be  entitled  to elect  all of the  directors  of  Mission  West-Maryland.
Pursuant to  agreement,  however,  the Company and the Berg Group have agreed to
take action necessary to elect the two Berg Group Board  Representatives  to the
board of directors.

The MGCL requires,  with certain  exceptions,  that the holders of two-thirds of
all shares entitled to vote on the matter must approve mergers,  consolidations,
share  exchanges,  transfers  of all or  substantially  all of the assets of the
corporation and dissolution  unless the charter  provides for a different number
not less than a majority. The Charter provides that such matters may be approved
by the holders of a majority of shares entitled to vote on the matter.

Under the MGCL, the charter of a Maryland corporation may include
supermajority voting provisions without restrictions.  The Charter currently
does not contain any supermajority voting provisions.

                             DENIAL OF VOTING RIGHTS

Under the MGCL,  holders of the outstanding  shares of any class of stock may be
denied all voting rights.

                       DIVIDENDS AND OTHER DISTRIBUTIONS

Under the CGCL, the Company may only make a distribution  to shareholders if (a)
its retained  earnings  immediately  prior to payment of the distribution are at
least  equal to the  amount of the  distribution,  or (b)  generally,  its total
assets  (determined  on the  basis  of  their  depreciated  historical  cost  in
accordance  with GAAP and  exclusive  of certain  intangible  assets and certain
other  charges  and  expenses)  are  equal to at  least 1 1/4  times  its  total
liabilities  (excluding  certain deferred items) immediately after giving effect
to the  distribution.  The CGCL also  prohibits a  California  corporation  from
making any  distribution  to  shareholders if the corporation is or, as a result
thereof,  would be likely to be unable to meet its  liabilities  as they mature.
The CGCL also imposes certain  further  limitations on  distributions  on common
stock if  capital  stock  with a  preference  on  distributions  of assets  upon
liquidation is outstanding.

                   DISSENTING SHAREHOLDER'S APPRAISAL RIGHTS

Under California law, shareholders of a California  corporation whose shares are
listed on a national  securities  exchange  (as are the  shares of the  Company)
generally do not have dissenters' rights unless the holders of 5% or more of the
class of outstanding shares claim the right or unless the corporation or any law
restricts the transfer of such shares.

                       STANDARD OF CONDUCT FOR DIRECTORS

Section  309 of the CGCL  requires  that a  director  perform  the  duties  of a
director  in good faith in the manner such  director  believes to be in the best
interests of the corporation and its shareholders and with such care,  including
reasonable inquiry, as an ordinarily prudent person in a like position would use
under similar circumstances.

                                  MARYLAND

                      DIVIDENDS AND OTHER DISTRIBUTIONS

The MGCL allows the payment of dividends and other distributions  unless,  after
giving effect to the distribution,  (a) the corporation would not be able to pay
its  debts  as they  become  due in the  usual  course  of  business  or (b) the
corporation's  total  assets  would be less  than  the sum of the  corporation's
liabilities  plus,  unless the  charter  provides  otherwise  (which the Charter
does),  the  amount  that  would be  needed  upon  dissolution  to  satisfy  the
preferential  rights  of  those  stockholders  whose  preferential  rights  upon
dissolution are superior to those receiving the distribution.

                    DISSENTING SHAREHOLDER'S APPRAISAL RIGHTS

The MGCL does not provide  appraisal  rights to stockholders of a corporation if
the corporation's shares are listed on a national securities  exchange,  such as
the  AMEX,  on  the  record  date  for  determining  those  stockholders  of the
corporation entitled to vote on the merger.

                        STANDARD OF CONDUCT FOR DIRECTORS

Section  2-405.1 of the MGCL requires that a director of a Maryland  corporation
perform his duties in good faith with a  reasonable  belief that his actions are
in the best  interests  of the  corporation  and with the care of an  ordinarily
prudent person in a like position ... under similar circumstances.

                            REMOVAL OF DIRECTORS

Under the CGCL and the California  Bylaws,  the entire board of directors or any
individual director may be removed from office by a vote of shareholders holding
a  majority  of the  outstanding  shares  entitled  to  vote at an  election  of
directors;  provided,  however,  that  unless the entire  board is  removed,  an
individual director shall not be removed,  unless (a) the number of shares voted
against  removal,  or not  consenting to such removal,  in the case of a written
consent,  would be insufficient to elect such director if voted  cumulatively at
an  election  at which the same  total  number of votes were cast and the entire
number  of  directors  authorized  at the time of such  director's  most  recent
election  were then being  elected or (b)  holders of the shares of any class or
series  entitled to elect one or more directors  shall vote to remove a director
so elected by said class or series.

The CGCL also provides that the superior  court of the proper county may, at the
request of shareholders holding at least 10% of the number of outstanding shares
of any class,  remove any director in case of  fraudulent  or dishonest  acts or
gross abuse of authority or discretion with reference to the corporation and may
bar from  reelection  any  director  so removed for a period  prescribed  by the
court.

                                  MARYLAND

                            REMOVAL OF DIRECTORS

Under the MGCL, the stockholders of a corporation may remove any director,  with
or  without  cause,  by the  affirmative  vote of a  majority  of all the  votes
entitled  to be cast for the  election of  directors,  unless the charter of the
corporation provides otherwise. The MGCL further states that if the stockholders
of any class or series are entitled separately to elect one or more directors, a
director elected by a class or series may not be removed without cause except by
the affirmative vote of a majority of all votes of that class or series,  unless
the charter of the corporation  provides otherwise (which the Charter does not).
The Charter  provides that  directors may be removed only for cause  (defined in
the  Charter to be with  respect to any  particular  director,  conviction  of a
felony or a final  judgment of a court of  competent  jurisdiction  holding that
such  director  caused  demonstrable,  material  harm to  Mission  West-Maryland
through  bad  faith  or  active  and  deliberate  dishonesty)  and  only  by the
affirmative  vote of at least a majority of the votes entitled to be cast in the
election of directors. The MGCL does not provide for the removal of directors by
a court upon petition of shareholders.

                      VACANCIES ON THE BOARD OF DIRECTORS

The California  Bylaws provide that vacancies on the board of directors,  except
for a vacancy created by the removal of a director,  may be filled by a majority
of the remaining  directors,  though less than a quorum,  or by a sole remaining
director.  Each  director so elected  shall hold office  until his  successor is
elected  at an  annual  or a  special  meeting  of the  shareholders.  A vacancy
occurring on the board of  directors of the Company  created by the removal of a
director may only be filled by the vote of a majority of the shares  entitled to
vote represented at a duly held meeting at which a quorum is present,  or by the
unanimous written consent of the shareholders.

The California Bylaws also provide that the shareholders may elect a director or
directors  at any  time to fill any  vacancy  or  vacancies  not  filled  by the
directors.  Any such election by written  consent  (other than to fill a vacancy
created by the  removal of a  director)  shall  require the consent of holders a
majority of the outstanding shares entitled to vote.

                                 MARYLAND

                    VACANCIES ON THE BOARD OF DIRECTORS

As permitted by the MGCL, the Maryland  Bylaws provide that (a) a vacancy on the
Mission  West-Maryland board of directors may be filled, if caused by any reason
other  than an  increase  in the  number  of  directors,  by a  majority  of the
remaining  directors,  even if such  number  is less  than a quorum  and (b) any
vacancy in the Mission West-Maryland board of directors caused by an increase in
the number of directors may be filled by a majority  vote of the entire  Mission
West-Maryland  board  of  directors;  provided  that a  vacancy  created  by the
departure  of a Berg Group  Representative  must be filled by another Berg Group
Board  Representative  until the time  that the right of the Berg  Group to name
directors has been terminated.  A director elected by the Mission  West-Maryland
board  of  directors   will  hold  office  until  the  next  annual  meeting  of
stockholders and until his or her successor is elected and qualifies.

                    COMMITTEES OF BOARD OF DIRECTORS

The  California  Bylaws  provide  that the  board  of  directors  may  designate
committees consisting of two or more directors. Such committees may have all the
authority of the board of directors  except with respect to: (a) the approval of
any action for which the CGCL also requires  shareholders'  approval or approval
of the issuance of outstanding shares, (b) the filling of vacancies on the board
of  directors  or on any  committee,  (c)  the  fixing  of  compensation  of the
directors  for serving on the board of  directors or on any  committee,  (d) the
amendment or repeal of bylaws or the adoption of new bylaws,  (e) the  amendment
or repeal of any resolution of the board of directors which by its express terms
is not so amendable or repealable, (f) a distribution to the shareholders of the
corporation (as defined in Section 166 of the CGCL),  except at a rate or in the
periodic amount or within a price range determined by the board of directors and
(g) the appointment of other committees of the board of directors or the members
thereof.

                     SPECIAL MEETINGS OF SHAREHOLDERS

The  CGCL  and  the  California   Bylaws  provide  that  a  special  meeting  of
shareholders may be called by the board of directors, the chairman of the board,
the president, or by the holders of shares entitled to cast not less than 10% of
the votes at the meeting.

                                 MARYLAND

                    COMMITTEES OF BOARD OF DIRECTORS

The Maryland  Bylaws provide that the board of directors may appoint  committees
composed of one or more directors and may delegate to such committees any of the
powers of the board of directors, except as prohibited by law. The MGCL provides
that the board of directors may delegate to committees  any of the powers of the
board of directors,  except the power to: (a) authorize  dividends on stock, (b)
issue stock (subject to certain  exceptions),  (c) recommend to the stockholders
any action  which  requires  stockholder  approval,  (d) amend the bylaws or (e)
approve  any  merger  or  share  exchange  which  does not  require  stockholder
approval.

                     SPECIAL MEETINGS OF SHAREHOLDERS


As permitted by the MGCL, the Maryland Bylaws provide that, a special meeting of
stockholders  may be called by the chief executive  officer,  the president or a

The California Bylaws provide that, subject to certain notice requirements,  any
action  which,  under any  provision  of the CGCL,  may be taken at a meeting of
shareholders,  may be taken  without a meeting if a consent in writing,  setting
forth the action so taken, is signed by the holders of outstanding shares having
not less than the minimum  number of votes that would be  necessary to authorize
or take such action at a meeting at which all shares  entitled  to vote  thereon
were present and voted.

                AMENDMENTS TO ARTICLES, CHARTER AND BYLAWS

Under the CGCL,  the  articles  of  incorporation  may be  amended  only if such
amendment is approved by the board of directors and by the holders of a majority
of the  outstanding  shares of stock  entitled to vote on the matter.  Under the
CGCL, a corporation's bylaws may be adopted,  amended or repealed by approval of
the  shareholders or by the board of directors;  however,  the  shareholders may
never be  divested  of the  power to  adopt,  amend or  repeal  the  bylaws.  In
addition, the CGCL provides that a bylaw changing a fixed number of directors or
the maximum or minimum number of directors may only be adopted by the holders of
a majority of the shares  entitled to vote. The California  Bylaws provide that,
subject to any exception, new bylaws may be adopted or the California Bylaws may
be amended or repealed by the affirmative  vote of a majority of the outstanding
shares entitled to vote, or by the written  consent of shareholders  entitled to
vote such shares,  and the California  Bylaws also provide that,  subject to the
rights of shareholders  set forth above and any other  exceptions,  bylaws other
than a bylaw or amendment  thereof  changing the authorized  number of directors
may be adopted, amended or repealed by the California Board.

                  ACTIONS BY WRITTEN CONSENT OF SHAREHOLDERS

The MGCL provides that any action that may be taken at a stockholder meeting may
be taken without a meeting only if (a) a unanimous written consent setting forth
the matter is signed by each stockholder  entitled to vote on the matter and (b)
a written waiver of any right to dissent is signed by each stockholder  entitled
to notice of the meeting but not entitled to vote at it.

                   AMENDMENTS TO ARTICLES, CHARTER AND BYLAWS

Under the MGCL, an amendment to the charter of a corporation must be approved by
the board of directors and the holders of  two-thirds of the shares  entitled to
vote on such matter unless such charter  provides for a different  vote not less
than a majority of such shares so entitled  to vote.  The Charter  provides  for
amendments  by the  affirmative  vote of the holders of a majority of the shares
entitled to vote on the matter.

As permitted by the MGCL, the Maryland Bylaws provide that the Maryland board of
directors has the exclusive power to adopt, amend or repeal any provision of the
Maryland Bylaws and to make new bylaws. The Maryland Bylaws further provide that

The California  Articles  contain no limitations or restrictions on ownership of
shares of the Company.


                       CERTAIN BUSINESS COMBINATIONS

The CGCL contains no business  combination  statute.  However, the CGCL requires
delivery of a fairness opinion in connection with (i) a tender offer,  including
a share  exchange  tender offer,  (ii) a merger (other than a short-form  merger
such as the  Reincorporation  Merger),  (iii) the  acquisition of control of the
outstanding  shares  or of  all  or  substantially  all  of  the  assets  of the
corporation in exchange for stock or other securities,  or (iv) a sale of all or
substantially  all of the  corporation's  assets proposed by an interested party
(an "Interested  Party") to the corporation or some or all of its  shareholders.
The CGCL  defines  "Interested  Party" to include a person who (a)  directly  or
indirectly  controls  the  corporation  that  is the  subject  of  the  proposed
combination,  (b) is directly or indirectly controlled by an officer or director
of the  subject  corporation  or (c) is an entity in which a material  financial
interest  is  held  by  any  director  or  executive   officer  of  the  subject
corporation.

                          LIMIT ON SHARE OWNERSHIP

As permitted by the MGCL, the Charter contains provisions limiting the ownership
and transfer of shares of stock of Mission  West-Maryland  which are intended to
ensure  that  Mission  West-Maryland  meets  the  requirements  of the  Code for
qualification   as  a  REIT.   See   "DESCRIPTION   OF   MISSION   WEST-MARYLAND
STOCK--Restrictions  on Transfer",  and "CERTAIN  PROVISIONS OF MARYLAND LAW AND
MISSION WEST-MARYLAND'S CHARTER AND BYLAWS."

                       CERTAIN BUSINESS COMBINATIONS

The  MGCL  restricts   certain  business   combinations   (including  a  merger,
consolidation,  share exchange, or, in certain circumstances,  an asset transfer
or  issuance  or  reclassification  of equity  securities)  between  a  Maryland
corporation  and an  "Interested  Stockholder"  or an affiliate  thereof.  These
provisions of Maryland law do not apply,  however, to business combinations that
are approved or exempted by the board of directors of the  corporation  prior to
the time that the "Interested Stockholder" becomes an "Interested  Stockholder."
See "CERTAIN PROVISIONS OF MARYLAND LAW AND MISSION  WEST-MARYLAND'S CHARTER AND
BYLAWS."

Pursuant to the authority  granted under the MGCL,  the board of directors  will
adopt a resolution providing that the "business  combination"  provisions of the
MGCL shall not apply to Mission West-Maryland.

                       CONTROL SHARE ACQUISITIONS

The  MGCL   eliminates   the  voting   rights  of  control   shares  in  certain
circumstances.  "Control  Shares"  are  defined in the MGCL as voting  shares of
stock  which,  if  aggregated  with all other  such  shares of stock  previously
acquired by the acquiror or in respect of which the acquiror is able to exercise
or direct the exercise of voting power  (except  solely by virtue of a revocable
proxy),  would  entitle  the  acquiror  to  exercise  voting  power in  electing
directors  within one of the following  ranges of voting power: (a) one-fifth or
more but less than one-third, (b) one-third or more but less than a majority, or
(c) a majority or more of all voting power. Control shares do not include shares
the acquiring  person is then entitled to vote as a result of having  previously
obtained  stockholder  approval.  See  "CERTAIN  PROVISIONS  OF MARYLAND LAW AND
MISSION WEST-MARYLAND'S CHARTER AND BYLAWS."

The  MGCL  permits  a  Maryland  corporation  to opt  out of the  control  share
acquisition statute by provision in its charter or bylaws. Mission West-Maryland
has  included  such a provision  in the Maryland  Bylaws.  However,  the Mission
West-Maryland board of directors may, at any time, without stockholder approval,
vote to amend the  Maryland  Bylaws to  eliminate  this  provision,  which would
result in Mission  West-Maryland being governed by the control share acquisition
statute.

contrary  to the best  interests  of the  Company  or its  shareholders  or that
involve  the  absence  of  good  faith  on the  part  of the  director,  (c) any
transaction from which a director derived an improper personal benefit, (d) acts
or  omissions  that show a reckless  disregard  for the  director's  duty to the
Company or its shareholders in circumstances in which the director was aware, or
should  have been aware,  in the  ordinary  course of  performing  a  director's
duties, of a risk of serious injury to the Company or its shareholders, (e) acts
or omissions that constitute an unexcused pattern of inattention that amounts to
an abdication of the  director's  duty to the Company or its  shareholders,  (f)
violations of the CGCL  requirements  governing  Company  contracts in which the
director  has a  material  interest,  or (g)  corporate  actions  for  which the
director  and the  Company are jointly and  severally  liable.  In general,  the
liability of officers may not be eliminated or limited under California law.

Pursuant to the MGCL and the Charter, the liability of directors and officers to

benefit or profit in money,  property or  services or (b) active and  deliberate
dishonesty  established  by a final  judgment as being  material to the cause of
action.  Thus,  the directors and officers of Mission  West-Maryland  may not be
liable for certain actions for which they might have otherwise been liable under

The CGCL contains provisions authorizing corporations to indemnify an officer or
director if the  officer or  director  acted in good faith and in a manner he or
she reasonably believed to be in the best interest of the corporation.  The CGCL
also permits the  corporation to advance  expenses to a director or officer,  if
the corporation receives an undertaking, usually in the form of a bond, by or on
behalf of the  director  or  officer  to repay  any  amounts  advanced  if it is
determined  ultimately  that the  director  or  officer  is not  entitled  to be
indemnified under the CGCL. Under the CGCL, the termination of any proceeding by
conviction  or upon a plea of nolo  contendere or its  equivalent  shall not, of
itself,  create a  presumption  that such person  failed to meet the standard of
conduct necessary to allow indemnification.

In addition,  the CGCL permits  indemnification  for  judgments of liability and
settlements in derivative  actions except that (a)  indemnification  may only be
made with court approval when a person is adjudged  liable to the corporation in
the performance of that person's duty to the  corporation  and its  shareholders
and (b)  indemnification  of amounts paid to settle and/or expenses  incurred to
defend a threatened or pending action shall not be made when such  threatened or
pending action is settled or otherwise  disposed of without court  approval.  No
indemnification  is permitted under the CGCL for the actions for which liability
for money damages may not be limited.

The California Bylaws provide that the agents of the Company are indemnified and
held harmless from all liability  arising from or related to a breach of duty to
the Company or its stockholders. The California Bylaws further provide that such
indemnification  is  not  exclusive  of  any  other  rights  the  agents  of the
corporation may have, including other rights pursuant to the laws of California.

                    INDEMNIFICATION OF DIRECTORS AND OFFICERS

     The  MGCL  permits   indemnification  of  officers  and  directors  against
judgments,  penalties,  fines and amounts paid in  settlement  of a  proceeding,
unless it is  established  that the act of the  director or officer was material
and was  committed  in bad  faith or was the  result of  active  and  deliberate
dishonesty,  or the director or officer received an improper personal benefit in
money, property or services, or in a criminal proceeding had reasonable cause to
believe the act or omission was unlawful.  Indemnification  is prohibited if the
person  seeking  indemnification  has been found liable to the  corporation in a
proceeding  brought  by or in the  right of the  corporation,  unless  otherwise
ordered by a court and then only for expenses.  In contrast to  California  law,
under Maryland law a termination of a proceeding by conviction or upon a plea of
nolo  contendere or its equivalent  creates a rebuttable  presumption  that such
person did not meet the requisite standard of conduct to allow indemnification.

     The Maryland Bylaws require Mission West-Maryland to indemnify, and advance
expenses to,  present and former  directors  and officers to the maximum  extent
permitted by Maryland law. For a complete  description of the indemnification of
directors and officers of Mission  West-Maryland  required by or permitted under
the MGCL, the Charter and the Maryland Bylaws, see "MANAGEMENT OF THE COMPANY --
Limitation of Liability and Indemnification."

               INDEMNIFICATION OF DIRECTORS AND OFFICERS (Continued)

As used in the indemnification  provisions of the California Bylaws, "agents" of
the Company  include any person who is or was a director,  officer,  employee or
other agent of the  Company,  or is or was serving at the request of the Company
as a  director,  officer,  employee  or agent of  another  foreign  or  domestic
corporation,  partnership,  joint venture,  trust or other enterprise,  or was a
director,  officer, employee or agent of a foreign or domestic corporation which
was a  predecessor  corporation  of the Company or of another  enterprise at the
request of such predecessor corporation.

                       INSPECTION OF BOOKS AND RECORDS

Under the CGCL,  upon written demand for any purpose  reasonably  related to the
shareholder's  interest as a  shareholder,  any  shareholder  of the Company may
inspect and copy the record of  shareholders  and  inspect  any other  corporate
books and records. A shareholder or shareholders (a) who hold at least 5% of the
outstanding  voting  shares  of the  corporation  or (b) who hold at least 1% of
those  voting  shares  and have  filed a Schedule  14A with the  Securities  and
Exchange  Commission shall have an absolute right to inspect and copy the record
of shareholders.  These rights apply both to any California  corporation and any
foreign  corporation  that keeps such records in California or has its principal
executive office in California. Thus, the inspection rights provided by the CGCL
will be applicable to Mission West-Maryland after the Reincorporation.

                       INSPECTION OF BOOKS AND RECORDS

The MGCL provides a right to inspect and copy the corporation's books of account
and stock ledger to persons who have been  stockholders for more than six months
and own at least 5% of any class of a Maryland corporation's outstanding shares.
In addition,  any stockholder of a Maryland corporation has the right to inspect
the bylaws, minutes of stockholders  meetings,  annual statements of affairs and
voting  trust  agreements  and to request that the  corporation  provide a sworn
statement  showing all stock and  securities  issued and all  consideration  per
share received therefor by the corporation within the preceding 12 months.

                      INTERESTED DIRECTOR TRANSACTIONS

Under California law, certain  contracts or transactions in which one or more of
a  corporation's  directors  has an  interest  are not void or  voidable  solely
because of such interest if certain conditions are met. Under California law (a)
either the  shareholders  or the board of directors must approve any contract or
transaction  after full  disclosure  of the  material  facts (and in the case of
board approval,  the contract or transaction must also be "just and reasonable")
or (b) the contract or  transaction  must have been just and  reasonable  at the
time  it was  authorized  or  approved.  California  law  has a  more  stringent
requirement  than Maryland law in  circumstances  where board approval is sought
with respect to an interested director transaction.  The contract or transaction
must be just and  reasonable and must be approved by a majority vote of a quorum
of the directors,  without counting the vote of any interested directors (except
that interested directors may be counted for purposes of establishing a quorum).

The CGCL also  provides  that any loan or  guarantee  to or for the benefit of a
director or officer of the  corporation  or its parent  requires the approval of
the  shareholders  unless  such loan or  guaranty is pursuant to a plan that has
been approved by the holders of a majority of the outstanding  shares.  However,
under the CGCL, the bylaws of a corporation  with more than 100 shareholders may
authorize  the  board of  directors  alone to  approve  loans or  guaranties  to
directors and officers.  The California  Bylaws do not currently  contain such a
provision allowing the directors to approve such loans or guaranties.

                      INTERESTED DIRECTOR TRANSACTIONS

Under the MGCL,  certain  contracts  or  transactions  in which one or more of a
corporation's  directors has an interest are not void or voidable solely because
of such interest if the contract or transaction (a) is approved by a majority of
the disinterested  directors or by a majority of votes cast by the disinterested
stockholders, in either case after full disclosure of the material facts, or (b)
is fair and reasonable to the corporation.

                  DESCRIPTION OF MISSION WEST-MARYLAND STOCK

   
     THE  FOLLOWING  SUMMARY  OF THE  TERMS  OF THE  CAPITAL  STOCK  OF  MISSION
WEST-MARYLAND  IS  QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE MGCL AND TO THE
CHARTER  AND  BYLAWS OF MISSION  WEST-MARYLAND.  COPIES OF THE  CHARTER  AND THE
BYLAWS ARE ATTACHED AS EXHIBITS TO THIS PROXY STATEMENT/PROSPECTUS.
    

GENERAL

     The Charter provides that Mission West-Maryland may issue up to 200,000,000
shares of New Common Stock and 20,000,000  shares of New Preferred  Stock.  Upon
completion of the  Reincorporation  Merger  8,193,594 shares of New Common Stock
will be issued  and  outstanding  and no shares of New  Preferred  Stock will be
designated into series or be issued and outstanding.

NEW COMMON STOCK

     All shares of New Common  Stock  offered  hereby  will be duly  authorized,
fully paid and  nonassessable.  Subject to the preferential  rights of any other
class or series of stock and to the  provisions  of the  Charter  regarding  the
restrictions  on  transfer of stock,  holders of shares of New Common  Stock are
entitled  to  receive  dividends  on such stock if, as and when  authorized  and
declared by the board of directors out of assets legally available  therefor and
to share ratably in the assets of Mission  West-Maryland  legally  available for
distribution to its stockholders in the event of its liquidation, dissolution or
winding  up after  payment  of or  adequate  provision  for all known  debts and
liabilities of Mission West-Maryland.

     Subject to the  provisions  of the Charter  regarding the  restrictions  on
transfer of stock,  each  outstanding  share of New Common  Stock  entitles  the
holder to one vote on all matters submitted to a vote of stockholders, including
the  election of  directors  and,  except as provided  with respect to any other
class or series of stock,  the holders of such shares will possess the exclusive
voting power. There is no cumulative voting in the election of directors,  which
means that the  holders of a majority  of the  outstanding  shares of New Common
Stock can elect all of the directors  then standing for election and the holders
of the remaining shares will not be able to elect any directors.

     Holders  of shares of New  Common  Stock  have no  preference,  conversion,
exchange,  sinking fund,  redemption or appraisal  rights and have no preemptive
rights to subscribe for any securities of Mission West-Maryland.  Subject to the
provisions  of the  Charter  regarding  the  restrictions  on transfer of stock,
shares of New  Common  Stock  will have equal  dividend,  liquidation  and other
rights.

     Under the MGCL, a Maryland corporation generally cannot dissolve, amend its
Charter,  merge, sell all or substantially all of its assets,  engage in a share
exchange  or engage in  similar  transactions  outside  the  ordinary  course of
business  unless approved by the  affirmative  vote of  stockholders  holding at
least  two-thirds  of the shares  entitled to vote on the matter unless a lesser
percentage (but not less than a majority of all of the votes entitled to be cast
on the matter) is set forth in the corporation's  Charter.  The Charter provides
that the  affirmative  vote of a majority  of all votes  entitled to be cast may
approve such matters.

     The Charter  provides  that,  to the extent  permitted by Maryland law from
time to time,  the board of  directors  of Mission  West-Maryland,  without  any
action by the stockholders of Mission West-Maryland,  may amend the Charter from
time to time to increase or decrease the aggregate  number of shares of stock or
the number of shares of stock of any class or series that Mission  West-Maryland
has authority to issue.  Such action is not presently  permitted  under Maryland
law, but may be permitted in the future.

NEW CLASSES OR SERIES OF STOCK

     The Charter authorizes the board of directors to classify or reclassify any
unissued  shares of New Preferred  Stock into other classes or series of classes
of stock and to  establish  the  number of shares in each class or series and to
set the preferences,  conversion and other rights, voting powers,  restrictions,
limitations as to dividends or other  distributions,  qualifications or terms or
conditions of redemption for each such class or series without any action by the
stockholders of Mission West-Maryland.

<PAGE>

POWER TO ISSUE ADDITIONAL SHARES OF NEW COMMON STOCK AND NEW PREFERRED STOCK

     Mission West-Maryland  believes that the power of the Board of Directors to
issue  additional  authorized  but  unissued  shares of New Common Stock and New
Preferred  and to classify or  reclassify  unissued  shares of New New Preferred
Stock and thereafter to cause Mission  West-Maryland to issue such classified or
reclassified  shares of stock will provide Mission  West-Maryland with increased
flexibility in structuring  possible future  financings and  acquisitions and in
meeting other needs which might arise. The additional classes or series, as well
as the New Common Stock and New Preferred Stock,  will be available for issuance
without  further  action by Mission  West-Maryland's  stockholders,  unless such
action is  required  by  applicable  law or the rules of any stock  exchange  or
automated  quotation system on which Mission  West-Maryland's  securities may be
listed or  traded.  Although  the Board of  Directors  has no  intention  at the
present time of doing so, it could authorize  Mission  West-Maryland  to issue a
class or series  that could,  depending  upon the terms of such class or series,
delay,  defer or  prevent  a  transaction  or a change  in  control  of  Mission
West-Maryland that might involve a premium price for holders of New Common Stock
or otherwise be in their best interest.

RESTRICTIONS ON TRANSFER

     REIT RESTRICTIONS. For Mission West-Maryland to qualify as a REIT under the
Code,  its shares of stock  must be  beneficially  owned by 100 or more  persons
during  at  least  335  days  of a  taxable  year  of  12  months  or  during  a
proportionate  part of a shorter  taxable year, and the REIT may not violate the
Five or Fewer Test during the last half of a taxable year.

     Because  the board of  directors  believes it is at present  essential  for
Mission  West-Maryland  to qualify as a REIT,  the  Charter,  subject to certain
exceptions,  contains  certain  restrictions on the number of shares of stock of
Mission  West-Maryland  that a person may own. The Charter  prohibits any person
from acquiring or holding, directly or indirectly, shares of New Common Stock in
excess of 9% in value of the  aggregate  of the  outstanding  shares of stock of
Mission  West-Maryland except for members of the Berg Group and their Affiliates
(other than the Company and the Operating Partnerships)  who, by agreement,  are
subject to the Berg Group Ownership Limit,  which is 20%. The Charter  prohibits
ownership  of New  Common  Stock by any  members  of the Berg Group or any other
shareholders  or  their  pledgees  or  assignees,   which  would  cause  Mission
West-Maryland to violate any of the REIT Requirements.

   
     Mission  West-Maryland's  board of directors,  in its sole discretion,  may
exempt a person other than the Berg Group from the Ownership Limit (an "Excepted
Holder"),  provided  that no  person  may  own  shares  of  stock,  directly  or
indirectly, which represent 9% or more of the value of the outstanding shares of
stock of Mission  West-Maryland  if that would  result in Mission  West-Maryland
being  "closely  held"  within  the  meaning  of  Section  856(h) of the Code or
otherwise would result in Mission West-Maryland failing to qualify as a REIT. In
order to be considered by the board of directors as an Excepted Holder, a person
also must not own,  directly or  indirectly,  an interest in a tenant of Mission
West-Maryland  (or a  tenant  of any  entity  owned  or  controlled  by  Mission
West-Maryland)  that would  cause  Mission  West-Maryland  to own,  directly  or
indirectly,  more than a 10%  interest in such a tenant.  The person  seeking an
exemption must represent to the  satisfaction  of the board of directors that it
will not violate the two aforementioned restrictions. The person also must agree
that any violation or attempted  violation of any of the foregoing  restrictions
will  result in the  automatic  transfer  of the  shares of stock  causing  such
violation to the Trust. The board of directors may require a ruling from the IRS
or an opinion of counsel,  in either case in form and substance  satisfactory to
the board of directors in its sole  discretion,  in order to determine or ensure
Mission  West-Maryland's status as a REIT. The management of the Company intends
to request the board of  directors of Mission  West-Maryland  to designate as an
Excepted  Holder any purchasers of shares in the Private  Placement  whose share
ownership as of the effective  date of the  Reincorporation  Merger  exceeds the
Ownership  Limit.  The  designation  shall not  apply,  however,  to  subsequent
purchases of shares of stock of Mission West-Maryland by such an Excepted Holder
except for shares  acquired  pursuant to a grant or award under the Stock Option
Plan or another written compensation plan approved by the board of directors.
    

     The  Charter  further   prohibits  (a)  any  person  from  beneficially  or
constructively owning shares of stock of Mission West-Maryland that would result
in Mission  West-Maryland  being "closely held" under Section 856(h) of the Code
or otherwise  cause Mission  West-Maryland  to fail to qualify as a REIT and (b)
any person from  transferring  shares of stock of Mission  West-Maryland if such
transfer would result in shares of stock of Mission West-Maryland being owned by
fewer than 100  persons.  Any  person who  acquires  or  attempts  or intends to
acquire  beneficial  or  constructive  ownership  of shares of stock of  Mission
West-Maryland that will or may violate

                                       -101-
<PAGE>

any of the foregoing  restrictions  on  transferability  and  ownership,  or any
person who would have owned  shares of the stock of Mission  West-Maryland  that
resulted  in a  transfer  of shares to the Trust,  is  required  to give  notice
immediately to Mission West-Maryland and provide Mission West-Maryland with such
other information as Mission West-Maryland may request in order to determine the
effect  of such  transfer  on  Mission  West-Maryland's  status  as a REIT.  The
foregoing  restrictions on  transferability  and ownership will not apply if the
board of directors, by affirmative vote of 75% of all directors, determines that
it is no longer in the best  interests  of Mission  West-Maryland  to attempt to
qualify, or to continue to qualify, as a REIT.

     If any transfer of shares of stock of Mission  West-Maryland  occurs which,
if effective,  would result in any person beneficially or constructively  owning
shares of stock of Mission  West-Maryland in excess or in violation of the above
transfer  or  ownership  limitations,  then  that  number  of shares of stock of
Mission  West-Maryland  the  beneficial  or  constructive   ownership  of  which
otherwise  would cause such person to violate such  limitations  (rounded to the
nearest  whole  share)  shall be  automatically  transferred  to a trust for the
exclusive  benefit of one or more charitable  beneficiaries,  and the Prohibited
Owner shall not acquire any rights in such shares. Such automatic transfer shall
be deemed to be  effective as of the close of business on the Business Day prior
to the date of such violative transfer.  Shares of stock held in the Trust shall
be  issued  and  outstanding  shares  of stock  of  Mission  West-Maryland.  The
Prohibited Owner shall not benefit  economically from ownership of any shares of
stock held in the Trust, shall have no rights to dividends and shall not possess
any rights to vote or other rights  attributable  to the shares of stock held in
the Trust.  The trustee of the Trust shall have all voting  rights and rights to
dividends  or other  distributions  with  respect to shares of stock held in the
Trust,  which  rights  shall  be  exercised  for the  exclusive  benefit  of the
Charitable  Beneficiary.  Any dividend or other  distribution  paid prior to the
discovery by Mission West-Maryland that shares of stock have been transferred to
the Trustee shall be paid by the recipient of such dividend or  distribution  to
the Trustee upon demand, and any dividend or other  distribution  authorized but
unpaid shall be paid when due to the Trustee.  Any dividend or  distribution  so
paid to the Trustee shall be held in trust for the Charitable  Beneficiary.  The
Prohibited  Owner shall have no voting  rights  with  respect to shares of stock
held in the Trust and,  subject to Maryland  law,  effective as of the date that
such shares of stock hve been  transferred to the Trust,  the Trustee shall have
the authority (at the Trustee's sole discretion) (i) to rescind as void any vote
cast by a Prohibited Owner prior to the discovery by Mission  West-Maryland that
such shares have been  transferred  to the Trust and (ii) to recast such vote in
accordance  with the  desires  of the  Trustee  acting  for the  benefit  of the
Charitable  Beneficiary.  However,  if Mission  West-Maryland  has already taken
irreversible  corporate action, then the Trustee shall not have the authority to
rescind and recast such vote.

     Within 20 days of receiving notice from Mission  West-Maryland  that shares
of stock of  Mission  West-Maryland  have been  transferred  to the  Trust,  the
Trustee shall sell the shares of stock held in the Trust to a person, designated
by the Trustee,  whose  ownership  of the shares will not violate the  ownership
limitations  set forth in the  Charter.  Upon such  sale,  the  interest  of the
Charitable  Beneficiary in the shares sold shall terminate and the Trustee shall
distribute  the net  proceeds  of the sale to the  Prohibited  Owner  and to the
Charitable Beneficiary as follows. The Prohibited Owner shall receive the lesser
of (i) the  price  paid  by the  Prohibited  Owner  for the  shares  or,  if the
Prohibited  Owner did not give value for the shares in connection with the event
causing the shares to be held in the Trust (e.g.,  a gift,  devise or other such
transaction),  the Market  Price of such shares on the day of the event  causing
the shares to be held in the Trust and (ii) the price per share  received by the
Trustee from the sale or other  disposition of the shares held in the Trust. Any
net sale proceeds in excess of the amount payable to the Prohibited  Owner shall
be paid immediately to the Charitable Beneficiary. If, prior to the discovery by
Mission  West-Maryland  that shares of stock have been transferred to the Trust,
such shares are sold by a Prohibited  Owner,  (i) such shares shall be deemed to
have been sold on behalf of the Trust and (ii) to the extent that the Prohibited
Owner  received  an amount for such  shares  that  exceeds  the amount that such
Prohibited  Owner  was  entitled  to  receive  pursuant  to  the  aforementioned
requirement, such excess shall be paid to the Trustee upon demand.

     In  addition,  shares of stock of Mission  West-Maryland  held in the Trust
shall be deemed to have been offered for sale to Mission  West-Maryland,  or its
designee, at a price per share equal to the lesser of (i) the price per share in
the transaction  that resulted in such transfer to the Trust (or, in the case of
a devise or gift,  the Market Price at the time of such devise or gift) and (ii)
the Market Price on the date Mission  West-Maryland,  or its  designee,  accepts
such  offer.  Mission  West-Maryland  shall have the right to accept  such offer
until the  Trustee  has sold the shares of stock held in the Trust.  Upon such a
sale to Mission West-Maryland, the interest of the Charitable Beneficiary in the
shares sold shall terminate and the Trustee shall distribute the net proceeds of
the sale to the Prohibited Owner.

                                       -102-
<PAGE>

     The  foregoing  restrictions  do not apply to shares  acquired  in original
issuance by members of the Berg Group. All certificates  representing  shares of
New Common  Stock  other than such shares  will bear a legend  referring  to the
restrictions described above.

     Every  owner of more than 5% (or such lower  percentage  as required by the
Code or the  regulations  promulgated  thereunder)  of all  classes or series of
Mission  West-Maryland's  stock, including shares of New Common Stock, within 30
days after the end of each taxable year,  is required to give written  notice to
Mission  West-Maryland stating the name and address of such owner, the number of
shares of each  class and  series of stock of  Mission  West-Maryland  which the
owner beneficially owns and a description of the manner in which such shares are
held.  Each such owner shall provide to Mission  West-Maryland  such  additional
information  as Mission  West-Maryland  may  request in order to  determine  the
effect, if any, of such beneficial ownership on Mission  West-Maryland's  status
as a REIT and to ensure  compliance with the Stock Ownership Limit. In addition,
each   shareholder   shall  upon  demand  be  required  to  provide  to  Mission
West-Maryland  such information as Mission  West-Maryland  may request,  in good
faith,  in order to determine  Mission  West-Maryland's  status as a REIT and to
comply with the requirements of any taxing  authority or governmental  authority
or to determine such compliance.

     These  ownership  limits could delay,  defer or prevent a transaction  or a
change in control of Mission  West-Maryland  that might  involve a premium price
for  the  New  Common  Stock  or  otherwise  be in  the  best  interest  of  the
stockholders.

     SECURITIES  RESTRICTIONS.  Subject to the  restrictions  set forth above in
"--Restrictions  on Transfer" and following the consummation of the transactions
contemplated  herein,  Mission  West-Maryland  will have  outstanding  8,193,594
shares of New Common Stock;  1,698,536 of which will be freely  transferable  in
the  public  market  without  restriction  or  further  registration  under  the
Securities Act, unless held by Affiliates of Mission West-Maryland, whose shares
will be subject  to the  resale  limitations  of Rule 144 and Rule  145(d).  The
6,495,058 shares of New Common Stock issued to the purchasers of Common Stock of
the  Company in the  Private  Placement  in exchange  for such  shares,  will be
eligible for resale  pursuant to the  Registration  Statement for as long as the
Company maintains its effectiveness.

     In  general,  under Rule 144,  an  Affiliate  of Mission  West-Maryland  is
subject  to  restrictions  on the manner of resale of such  Affiliate's  shares.
Further, the number of shares sold by an Affiliate in any three-month period may
not exceed the greater of 1% of the shares of New Common Stock then  outstanding
or the reported average weekly trading volume of the New Common Stock during the
four calendar weeks  immediately  preceding the date on which notice of the sale
is sent to the  Commission.  Any sale by an Affiliate  of Mission  West-Maryland
will also be subject to certain notice  requirements and availability of current
public information concerning Mission West-Maryland.

REINVESTMENT AND SHARE PURCHASE PLAN

     Mission  West-Maryland  may  adopt a  Distribution  Reinvestment  and Share
Purchase  Plan that would allow  stockholders  to  automatically  reinvest  cash
distributions on their  outstanding  shares of Common Stock and/or L.P. Units to
purchase additional shares of Common Stock at a discounted price and without the
payment of any brokerage commission or service charge.  Stockholders and Limited
Partners would also have the option of investing limited  additional  amounts by
making cash  payments.  No decision has been made yet by the Company  whether or
not to adopt such a plan,  and there can be no  assurance  that such a plan will
ever be adopted by Mission West-Maryland.

                     CERTAIN PROVISIONS OF MARYLAND LAW AND
                  OF MISSION WEST-MARYLAND'S CHARTER AND BYLAWS


     THE  FOLLOWING  SUMMARY OF CERTAIN  PROVISIONS  OF MARYLAND  LAW AND OF THE
CHARTER AND  MARYLAND  BYLAWS DOES NOT PURPORT TO BE COMPLETE  AND IS SUBJECT TO
AND  QUALIFIED  IN ITS  ENTIRETY BY REFERENCE TO MARYLAND LAW AND TO THE CHARTER
AND BYLAWS, COPIES OF WHICH ARE EXHIBITS TO THIS PROXY STATEMENT/PROSPECTUS. SEE
"ADDITIONAL INFORMATION."

THE BOARD OF DIRECTORS

   
     The Charter  provides  that the number of directors of the Company shall be
five and that number may be increased or  decreased  pursuant to the bylaws.  As
long as the Berg Group members and their Affiliates  (other than the Company and
the  Operating Partnerships)  own  at  least  15%  of  the  voting  shares  on a
Fully-Diluted  basis, at least two directors must satisfy the  qualification  of
being  nominated by the Berg Group  members.  At least one director must satisfy
such  qualification  if Berg Group's  aggregate  percentage  ownership of voting
shares on a  Fully-Diluted  basis is at least 10%,  although  less than 15%. The
Maryland  Bylaws provide that the board of directors may establish,  increase or
decrease the number of directors,  provided  that the number of directors  shall
never be less than the minimum  number  required by Maryland  law, nor more than
15. In general,  any vacancy  will be filled,  at any regular  meeting or at any
special  meeting  called  for  that  purpose,  by a  majority  of the  remaining
directors,  except  that a vacancy  resulting  from an increase in the number of
directors  must be filled by a majority  of the  entire  board of  directors.  A
vacancy created by the departure of a Berg Group Board Representative,  however,
must be filled by another  Berg Group Board  Representative  until the date that
the right of the Berg Group to name the Berg  Group  Board  Representatives  has
expired.
    

REMOVAL OF DIRECTORS

     The  Charter  provides  that a director  may be removed  only for cause (as
defined in the Charter) and only by the affirmative  vote of at least a majority
of the votes entitled to be cast in the election of directors.  This  provision,
when coupled with the provision in the Maryland Bylaws  authorizing the board of
directors to fill vacant  directorships,  precludes  stockholders  from removing
incumbent  directors  without  cause and filling the  vacancies  created by such
removal with their own nominees.

BUSINESS COMBINATIONS

     Under  the  MGCL,  certain  "business  combinations"  (including  a merger,
consolidation, share exchange or, in certain circumstances, an asset transfer or
issuance  or   reclassification   of  equity  securities)   between  a  Maryland
corporation and any person who beneficially owns 10% or more of the voting power
of the corporation's  shares or an Affiliate of the corporation who, at any time
within the two-year  period prior to the date in  question,  was the  beneficial
owner of 10% or more of the voting power of the then-outstanding voting stock of
the  corporation  (an  "Interested  Stockholder")  or an  Affiliate  of  such an
Interested  Stockholder are prohibited for five years after the most recent date
on  which  the  Interested   Stockholder  becomes  an  Interested   Stockholder.
Thereafter,  any such business  combination  must be recommended by the board of
directors of such  corporation and approved by the affirmative  vote of at least
(a) 80% of the votes  entitled  to be cast by holders of  outstanding  shares of
voting stock of the  corporation  and (b) two-thirds of the votes entitled to be
cast by holders of voting stock of the corporation other than shares held by the
Interested  Stockholder  with  whom  (or  with  whose  affiliate)  the  business
combination is to be effected, unless, among other conditions, the corporation's
common  stockholders  receive a minimum price (as defined in the MGCL) for their
shares  and  the  consideration  is  received  in cash  or in the  same  form as
previously paid by the Interested  Stockholder for its shares.  These provisions
of the MGCL do not apply, however, to business combinations that are approved or
exempted by the board of directors of the corporation prior to the time that the
Interested   Stockholder   becomes   an   Interested   Stockholder.   After  the
Reincorporation Merger the Berg Group will beneficially own more than 10% of the
Company's voting shares, as will one of the purchasers in the Private Placement.
They would,  therefore,  be subject to the business combination provision of the
MGCL.  However,  pursuant to the  statute,  the Company has exempted any usiness
combinations  involving  the  Berg  Group  and  any  purchaser  in  the  Private
Placement.  Consequently,  the five-year prohibition and the super-majority vote
requirements will not apply to business combinations between any of them and the
Company.  As a result,  the Berg Group and such  purchaser  may be able to enter
into business combinations with the Company that may not be in the best interest
of its stockholders  without  compliance by the Company with the  super-majority
vote requirements and the other provisions of the statute.

CONTROL SHARE ACQUISITIONS

     The MGCL provides that "control shares" of a Maryland  corporation acquired
in a "control  share  acquisition"  have no voting  rights  except to the extent
approved by a vote of two-thirds of the votes entitled to be

                                       -104-
<PAGE>

cast on the matter, excluding shares of stock owned by the acquiror, by officers
or by directors  who are  employees  of the  corporation.  "Control  Shares" are
voting shares of stock which,  if aggregated with all other such shares of stock
previously  acquired by the acquiror or in respect of which the acquiror is able
to exercise or direct the exercise of voting power (except solely by virtue of a
revocable  proxy),  would  entitle  the  acquiror to  exercise  voting  power in
electing  directors  within one of the  following  ranges of voting  power:  (i)
one-fifth or more but less than one-third,  (ii) one-third or more but less than
a majority,  or (iii) a majority or more of all voting power.  Control shares do
not include shares the acquiring  person is then entitled to vote as a result of
having previously obtained  stockholder  approval. A "control share acquisition"
means the acquisition of control shares, subject to certain exceptions.

     A person who has made or proposes to make a control share acquisition, upon
satisfaction of certain  conditions  (including an undertaking to pay expenses),
may compel the board of directors of the  corporation to call a special  meeting
of  stockholders  to be held  within 50 days of demand to  consider  the  voting
rights of the shares.  If no request for a meeting is made, the  corporation may
itself present the question at any stockholders meeting.

     If voting rights are not approved at the meeting or if the acquiring person
does not deliver an acquiring person statement as required by the statute,  then
subject to certain conditions and limitations, the corporation may redeem any or
all of the control shares (except those for which voting rights have  previously
been  approved)  for fair value  determined,  without  regard to the  absence of
voting rights for the control  shares,  as of the date of the last control share
acquisition  by the  acquiror  or of any  meeting of  stockholders  at which the
voting rights of such shares are considered  and not approved.  If voting rights
for control  shares are  approved  at a  stockholders  meeting and the  acquiror
becomes  entitled to vote a majority of the shares  entitled to vote,  all other
stockholders  may  exercise  appraisal  rights.  The fair value of the shares as
determined  for  purposes  of such  appraisal  rights  may not be less  than the
highest price per share paid by the acquiror in the control share acquisition.

     The control share acquisition statute does not apply (a) to shares acquired
in a merger,  consolidation  or share exchange if the  corporation is a party to
the  transaction or (b) to  acquisitions  approved or exempted by the charter or
bylaws of the corporation.

     The Maryland  Bylaws  contain a provision  exempting from the control share
acquisition  statute  any and all  acquisitions  by any person of the  Company's
shares  of stock.  There can be no  assurance  that such  provision  will not be
amended or eliminated at any time in the future.

BOARD QUORUM AND SPECIAL VOTING REQUIREMENTS

     Generally, a majority of the total number of directors constitutes a quorum
for the  transaction of business under the MGCL.  However,  the Maryland  Bylaws
provide that a quorum for any meeting of the board of directors must include the
Required Directors.

     The Maryland  Bylaws include special voting  requirements  for the board of
directors,  such that  until the  Protective  Provisions  Expiration  Date,  the
Company will not take or permit to be taken any of the following actions without
the approval of the Required Directors:  (i) establishing a quorum for a meeting
which is not attended by Mr. Berg or his designee;  (ii) amending the Charter or
the bylaws;  (iii) merging with or into another entity; and (iv) any sale of all
or substantially all of the Company's  assets.  The Maryland Bylaws also provide
that the  approval  of more than 75% of the entire  board of  directors  will be
required for (i) the  Company's  taking title to assets or  conducting  business
other than  through  the  Operating Partnerships,  (ii) the  termination  of the
Company's status as a REIT, and (iii) incurring indebtedness in excess of 50% of
the Company's Total Market Capitalization.

AMENDMENT TO THE CHARTER

     The Charter,  including its provisions regarding removal of directors,  may
be amended only by the  affirmative  vote of the holders of a majority of all of
the votes entitled to be cast on the matter. In addition, the bylaws require the
approval by the Berg Group of all amendments to the Charter.

DISSOLUTION OF THE COMPANY

     The  dissolution of the Company must be advised by a majority of the entire
board of directors and approved by the  stockholders by the affirmative  vote of
the holders of a majority of all of the votes entitled to be cast on the matter.

                                    -105-
<PAGE>

ADVANCE NOTICE OF DIRECTOR NOMINATIONS AND NEW BUSINESS

     The  bylaws  provide  that  (a)  with  respect  to  an  annual  meeting  of
stockholders,  nominations of persons for election to the board of directors and
the proposal of business to be considered by  stockholders  may be made only (i)
pursuant to Mission  West-Maryland's  notice of the  meeting,  (ii) by or at the
direction of the board of directors or (iii) by a stockholder who is entitled to
vote at the meeting and has  complied  with the advance  notice  procedures  set
forth in the bylaws and (b) with  respect to special  meetings of  stockholders,
only the business specified in Mission  West-Maryland's notice of meeting may be
brought  before the  meeting of  stockholders  and  nominations  of persons  for
election  to the board of  directors  may be made only (i)  pursuant  to Mission
West-Maryland's  notice of the meeting, (ii) by or at the direction of the board
of directors or (iii) provided that the board of directors has  determined  that
directors shall be elected at such meeting,  by a stockholder who is entitled to
vote at the meeting and has  complied  with the advance  notice  provisions  set
forth in the bylaws.

CONFLICT OF INTEREST

     The Charter  provides that no director  will be  prohibited  from voting or
taking any action as a director  because of any actual or  apparent  conflict of
interest  between the  director  and the Company and that no action taken by the
board of directors will be void or voidable  because a majority of directors are
affiliated  with the Berg  Group or that an  action  is  beneficial  to the Berg
Group, to the extent permitted by law.

ANTI-TAKEOVER EFFECT OF CERTAIN PROVISIONS OF MARYLAND LAW AND OF THE CHARTER
AND BYLAWS

     The control share acquisition provisions of the MGCL, and the provisions of
the Charter on removal of directors  and the advance  notice  provisions  of the
bylaws could  delay,  defer or prevent a  transaction  or a change in control of
Mission  West-Maryland  that might  involve a premium  price for  holders of New
Common Stock or otherwise be in their best interest.

   ACCOUNTING TREATMENT OF THE BERG ACQUISITION AND THE REINCORPORATION MERGER

   
     The UPREIT  Transactions and the Acquired  Properties will be accounted for
as a purchase.  Accordingly,  the costs of the acquisition were allocated to the
assets and  liabilities  assumed based upon their  respective fair values at the
effective date of the acquisition.
    

                        FEDERAL INCOME TAX CONSIDERATIONS

     The  following  summary  of  material  federal  income  tax  considerations
concerning  Mission  West-Maryland  (referred  to also as the  "Company" in this
discussion) after the  Reincorporation  Merger and the election to become a REIT
is based on current law, is for general  information only and is not tax advice.
This  discussion is for general  purposes only and does not purport to deal with
all aspects of taxation that may be relevant to particular shareholders in light
of their  personal  investment  or tax  circumstances,  or to  certain  types of
shareholders (including insurance companies, tax-exempt organizations, financial
institutions  or  broker-dealers,  foreign  corporations,  persons  who  are not
citizens or residents of the United  States,  and persons who hold stock as part
of a conversion  transaction,  as part of a hedging transaction or as a position
in a straddle for tax purposes)  subject to special  treatment under the federal
income tax laws.

     This summary does not provide a detailed discussion of any state, local, or
foreign tax  considerations.  This  summary is  qualified in its entirety by the
applicable provisions of the Code, rules and regulations promulgated thereunder,
and  administrative  and judicial  interpretations  thereof,  all as of the date
hereof  and  all of  which  are  subject  to  change  (which  change  may  apply
retroactively).  The Taxpayer Relief Act of 1997 (the "1997 Act") was enacted on
August 5, 1997. The 1997 Act contains many  provisions  which  generally make it
easier to  operate  and to  continue  to  qualify  as a REIT for  taxable  years
beginning  after  the  date of  enactment  (which,  for the  Company,  would  be
applicable  commencing with its taxable year beginning January 1, 1998). The IRS
Restructuring  and Reform Bill of 1998, which has been passed by Congress and is
awaiting  signature by the  President,  changes  certain  aspects of the federal
income tax law applicable to REITs (the "1998 Act"), and their shareholders.

     EACH  PROSPECTIVE  PURCHASER  IS  ADVISED TO  CONSULT  HIS OWN TAX  ADVISOR
REGARDING THE SPECIFIC TAX  CONSEQUENCES TO HIM OF THE COMPANY'S  ELECTION TO BE
TAXED AS A REAL ESTATE INVESTMENT TRUST,  INCLUDING THE FEDERAL,  STATE,  LOCAL,
FOREIGN AND OTHER TAX CONSEQUENCES OF POTENTIAL CHANGES IN APPLICABLE TAX LAWS.

TAXATION OF THE COMPANY

     GENERAL.  The Company  plans to elect to be taxed as a REIT under  Sections
856 through 860 of the Code and the applicable  Treasury  Regulations (the "REIT
Provisions")  commencing  with its taxable year ending  December  31, 1998.  The
Company  believes  that it is organized and will be operated in such a manner as
to qualify  for  taxation  as a REIT under the REIT  Provisions  and the Company
intends to  continue  to operate in such a manner.  No  assurance  can be given,
however,  that the Company  will  operate in a manner so as to qualify or remain
qualified as a REIT.

     The REIT Provisions are highly technical and complex.  The material aspects
of the REIT Provisions are summarized below.

     In the opinion of Graham & James LLP, commencing with the Company's taxable
year ending on December  31, 1998,  the Company will be organized in  conformity
with the requirements for  qualification  and taxation as a REIT, and its method
of operation will enable it to meet the requirements for continued qualification
and taxation as a REIT. This opinion is based on various assumptions relating to
the  organization  and operation of the Company and the  Operating Partnerships,
however,  and is conditioned  upon certain  representations  made by the Company
about factual matters relating to the organization and expected operation of the
Company and the Operating Partnerships.  In addition, this opinion is based upon
the  factual   representations  of  the  Company  concerning  its  business  and
properties as set forth in this Proxy  Statement/Prospectus and assumes that the
actions described in this Proxy Statement/Prospectus are completed as described.
Moreover,  qualification  and  taxation  as a REIT  depends  upon the  Company's
ability to meet,  through actual annual operating  results,  the various income,
asset,  distribution,  stock ownership, and other qualification tests imposed by
the REIT Provisions

                                    -107-
<PAGE>

discussed  below,  the results of which will not be reviewed by nor be under the
control of Graham & James LLP.  Accordingly,  no assurance can be given that the
actual results of the Company's  operation for any particular  taxable year will
satisfy such requirements. See "Loss of REIT Qualification".

     If the Company  qualifies for taxation as a REIT, it generally  will not be
subject to federal corporate incom e taxes on the portion of its net income that
is currently  distributed  to its  shareholders.  This  treatment  substantially
eliminates the "double taxation" (at the corporate and shareholder  levels) that
generally  results from investment in a corporation.  The Company may be subject
to federal income and excise tax, however, as follows:

     (i)  The  Company  will  be  taxed  at  regular   corporate  rates  on  any
     undistributed  REIT taxable  income,  including  undistributed  net capital
     gains.

     (ii)  Under  certain  circumstances,  the  Company  may be  subject  to the
     "corporate alternative minimum tax" on its items of tax preference.

     (iii) If the Company has (A) net income from the sale or other  disposition
     of "foreclosure  property" which is held primarily for sale to customers in
     the ordinary course of business or (B) other  nonqualifying net income from
     foreclosure  property,  it will be  subject  to tax on such  income  at the
     highest corporate rate.

     (iv) If the Company has net income from  "prohibited  transactions"  (which
     are, in  general,  certain  sales or other  dispositions  of property  held
     primarily for sale to customers in the ordinary  course of business,  other
     than foreclosure property), such income will be subject to a 100% tax.

     (v) If the Company  fails to satisfy  the 75% gross  income test or the 95%
     gross income test (as discussed below),  but preserves its qualification as
     a REIT because certain other requirements have been met, it will be subject
     to a 100% tax on the net income  attributable  to the greater of the amount
     by which the Company  fails the 75% or 95% test,  multiplied  by a fraction
     intended to reflect the Company's profitability.

     (vi) If the Company should fail to distribute  during each calendar year at
     least the sum of (A) 85% of its REIT ordinary income for such year, (B) 95%
     of  its  REIT  capital  gain  net  income  for  such  year,   and  (C)  any
     undistributed  taxable  income from prior  periods,  the  Company  would be
     subject to a 4% excise tax on the excess of such required distribution over
     the  amounts  actually   distributed.   The  1998  Act  provides  that  all
     distributions  by the REIT shall be deemed to come first from earnings from
     non-REIT years.

     (vii) If during the ten-year period (the "Recognition Period") beginning on
     the first day of the first taxable year for which the Company  qualifies as
     a REIT, the Company recognizes gain in the disposition of any asset held by
     the Company as of the beginning of such  Recognition  Period,  then, to the
     extent of the excess of (a) the fair  market  value of such asset as of the
     beginning of such Recognition  Period over (b) the Company's adjusted basis
     in such asset as of the beginning of such Recognition Period (the "Built-in
     Gain"),  such gain will be subject to tax at the highest regular  corporate
     rate. The Company will not acquire any assets until the closing of the Berg
     Acquisition,  and they will hold no such  assets  at the  beginning  of the
     Recognition Period.

     (viii) If the Company subsequently  acquires any asset from a C corporation
     (i.e.,  generally a corporation subject to full  corporate-level  tax) in a
     transaction  in which  the  basis of the  asset in the  Company's  hands is
     determined  by reference to the basis of the asset (or any other  property)
     in the hands of the C corporation,  and the Company  recognizes gain on the
     disposition of such asset during the  Recognition  Period  beginning on the
     date on which such asset was acquired by the Company,  then,  to the extent
     of the  Built-in  Gain,  such gain will be  subject  to tax at the  highest
     regular  corporate  rate.  The result  described  above with respect to the
     recognition  of Built-in  Gain during the  Recognition  Period  assumes the
     Company will make an election in accordance with Notice 88-19 issued by the
     Internal  Revenue Service (the "IRS").  See "--Tax Aspects of the Operating
     Partnerships--Partnership  Allocations"  and " Tax Allocations with Respect
     to Contributed Properties" below.

     REQUIREMENTS FOR  QUALIFICATION.  The Code defines a REIT as a corporation,
trust or association: (1) which is managed by one or more trustees or directors;
(2) the beneficial ownership of which is evidenced by transferable shares, or by
transferable  certificates of beneficial interest; (3) which would be taxable as
a domestic  corporation,  but for Code  sections  856 though  859;  (4) which is
neither a financial  institution  nor an  insurance  company  subject to certain
provisions of the Code; (5) the beneficial  ownership of which is held by 100 or
more persons  (determined  without  reference to any rules of attribution);  (6)
during the last half of each taxable year not

                                    -108-
<PAGE>

more than 50% in value of the outstanding  stock of which is owned,  directly or
constructively,  by "five  or  fewer"  individuals  (as  defined  in the Code to
include certain entities) (the "Five or Fewer Test"); (7) that makes an election
to be a REIT (or has made such  election  for a previous  taxable year which has
not been revoked or  terminated)  and  satisfies  all relevant  filing and other
administrative  requirements established by the IRS that must be met in order to
elect and maintain REIT status; (8) that uses a calendar year for federal income
tax purposes and complies with the  recordkeeping  requirements  of the Code and
Treasury Regulations promulgated thereunder;  and (9) which meets certain income
and asset tests,  described below. The Code provides that conditions (1) to (4),
inclusive,  must be met during the entire taxable year,  that condition (5) must
be met  during  at least 335 days of a taxable  year of 12  months,  or during a
proportionate  part of a taxable year of less than 12 months and that  condition
(6) must be met for the last six months of each taxable  year. As of the date of
this  Proxy  Statement/Prospectus  the  Company  believes  that it will  satisfy
conditions (5) and (6). The Charter contains restrictions regarding transfers of
shares,  which are intended to assist the Company in  continuing  to satisfy the
share ownership  requirements  described in (5) and (6). In  particular,although
the Berg Group may own as much as 20% of the  outstanding  stock  under the Berg
Group Ownership  Limit,  which likely  represents  ownership by two individuals,
Carl E. Berg and Clyde J. Berg, for Five or Fewer Test purposes,  the members of
the Berg Group may not acquire any  additional  shares if it would result in the
Company's failure to satisfy the Test. Such transfer  restrictions are described
in "DESCRIPTION OF MISSION WEST-MARYLAND STOCK--Restrictions on Transfer."

     In its proposed budget for the 1999 fiscal year, the Clinton Administration
has  proposed  to impose an  ownership  requirement  for REIT  qualification  in
addition to the Five or Fewer Test.  The proposal would create a limit of 50% of
the  combined  voting power of all classes of voting stock or the total value of
all classes of stock any one person or entity could own. Unlike the current Five
or Fewer Test,  which permits a "look through" for certain entities to determine
the number of owners,  the Clinton proposal would apply to any person (including
a  partnership,  corporation  or trust).  In addition,  the  proposal  calls for
attribution  of  ownership   between  a  partnership  and  its  partners  and  a
corporation and its shareholders  (with a 10% threshold for  attribution).  This
proposal has not been included in the 1998 Act.

     Pursuant to the 1997 Act, for the Company's  taxable years commencing on or
after January 1, 1998, if the Company complies with regulatory rules pursuant to
which it is  required  to send  annual  letters to  certain of its  shareholders
requesting information regarding the actual ownership of its stock, but does not
know, or exercising reasonable diligence would not have known, whether it failed
to meet the requirement that it not be closely held, the Company will be treated
as having met the Five or Fewer Test. If the Company were to fail to comply with
these  regulatory  rules for any year, it would be subject to a $25,000 penalty.
If the  Company's  failure to comply  was due to  intentional  disregard  of the
requirements,  the  penalty  would be  increased  to  $50,000.  However,  if the
Company's failure to comply was due to reasonable cause and not willful neglect,
no penalty would be imposed.

     Section 856(i) of the Code provides that a corporation that is a "qualified
REIT subsidiary" shall not be treated as a separate corporation, and all assets,
liabilities  and items of  income,  deduction  and credit of a  "qualified  REIT
subsidiary"  shall be  treated  as  assets,  liabilities  and  items of  income,
deduction  and credit of the REIT.  Pursuant to the 1997 Act, for the  Company's
taxable  years  beginning  on or  after  January  1,  1998,  a  "qualified  REIT
subsidiary"  is a corporation  all of the capital stock of which is owned by the
REIT.  Pursuant to this amendment,  the Company will have the ability,  if it so
chooses,  to acquire an existing  corporation  that will qualify as a "qualified
REIT  subsidiary",  as opposed to having to form such a subsidiary.  The Company
may form or acquire "qualified REIT subsidiaries" in the future. In applying the
income and asset tests described  below, a "qualified REIT  subsidiary"  will be
ignored and all assets, liabilities and items of income, deduction and credit of
such  "qualified  REIT  subsidiary"  will be treated as assets,  liabilities and
items of  income,  deduction  and  credit  of the  Company.  A  "qualified  REIT
subsidiary"  of the  Company  will not be subject to  federal  corporate  income
taxation,  although  it may be  subject to state and local  taxation  in certain
states.

     In the  case  of a REIT  such  as  the  Company  which  is a  partner  in a
partnership,  Treasury  Regulations  provide that the REIT will be deemed to own
its  proportionate  share of the assets of the partnership and will be deemed to
be  entitled to the income of the  partnership  attributable  to such share.  In
addition, the character of the assets and gross income of the partnership retain
the same  character  in the hands of the REIT for purposes of Section 856 of the
Code, including satisfying the gross income tests and the asset tests. Thus, the
Company's proportionate share of the assets,  liabilities and items of income of
the Operating Partnerships  will be treated as assets,  liabilities and items of
income of the Company for purposes of applying the requirements described below.

                                    -109-
<PAGE>

     GROSS  INCOME  TESTS.  In order to maintain  qualification  as a REIT,  the
Company annually must satisfy two gross income requirements, as follows:

     (i) At least 75% of the Company's gross income (excluding gross income from
     prohibited  transactions) for each taxable year must be derived directly or
     indirectly from investments  relating to real property or mortgages on real
     property   (including   "rents   from  real   property"   and,  in  certain
     circumstances, interest) or from certain types of temporary investments.

     (ii) At least 95% of the  Company's  gross income  (excluding  gross income
     from  prohibited  transactions)  for each taxable year must be derived from
     such real property  investments and from dividends,  interest and gain from
     the sale or disposition of stock or securities (or from any  combination of
     the foregoing).

     Rents received by the Company will qualify as "rents from real property" in
satisfying  the gross income  requirements  for a REIT  described  above only if
several conditions are met, including the following:

     (i) The  amount of rent must not be based in whole or in part on the income
     or profits of any person from the property.  However, an amount received or
     accrued  generally  will not be  excluded  from the term  "rents  from real
     property"  solely  by  reason  of  being  based  on a fixed  percentage  or
     percentages of receipts or sales.

     (ii) Rents  received  from a tenant  will not  qualify as "rents  from real
     property" in satisfying the gross income tests if the Company,  or an owner
     of 10% or more of the Company,  directly or constructively owns 10% or more
     of such  tenant (a  "Related  Party  Tenant").  Constructive  ownership  is
     determined  under the  attribution  rules of  Section  318 of the Code,  as
     modified by Section 856(d)(5) of the Code.

     (iii) If rent attributable to personal property,  leased in connection with
     a lease of real  property,  is greater than 15% of the total rent  received
     under the lease,  then the portion of rent  attributable  to such  personal
     property will not qualify as "rents from real property."

     (iv) Rents received will not qualify as "rents from real property",  unless
     the Company generally does not operate or manage the property or furnish or
     render  services to the  tenants of such  property,  other than  through an
     independent  contractor from whom the REIT derives no revenue.  The Company
     may,  however,  directly  perform  certain  services  that are  "usually or
     customarily  rendered" in connection with the rental of space for occupancy
     only and are not  otherwise  considered  "rendered to the  occupant" of the
     property.  In  addition,  for its 1998  taxable  year and  thereafter,  the
     Company  is  permitted  to receive  up to 1% of its gross  income  from the
     provision  of  non-customary  services  and still  treat all other  amounts
     received from such property as "rents from real property."

     The term  "interest"  generally  does not  include  any amount  received or
accrued  (directly or indirectly) if the determination of such amount depends in
whole or in part on the income or profits of any person.  An amount  received or
accrued generally will not be excluded from the term "interest," however, solely
by reason of being based on a fixed  percentage  or  percentages  of receipts or
sales.

     The Company  intends for all of its income to be derived  from its interest
in the  Operating Partnerships,  and expects  that the  Operating  Partnerships'
ownership  of the  Properties  will give rise to income  which  will  enable the
Company to satisfy all of the income tests  described  above.  All of the "rents
from  real  property"  that the  Company  expects  to  receive  or  expects  the
Partnership to receive will satisfy the foregoing conditions. Certain Properties
or portions  thereof have been leased to  corporations  in which  members of the
Berg  Group  own in excess of 10% of the  total  number of  outstanding  shares.
Initially,  the Berg Group will own less than 2% of the  Common  Stock,  and the
Company is not aware of any other shareholders  owning interests in such tenants
which would result in such entities being deemed Related Party Tenants. However,
the future  acquisition of 10% or more of the Company's Common Stock by the Berg
Group,  upon exercise of their  Exchange  Rights or otherwise,  could cause such
entities to be treated as Related Party  Tenants.  The members of the Berg Group
have agreed not to acquire shares of the Company's  Common Stock if, in the sole
judgment of the Independent Directors Committee, their ownership of Common Stock
would result in the loss of the Company's status as a REIT.

     RELIEF  PROVISIONS.  Should the Company  fail to satisfy one or both of the
75% or 95% gross income tests for any taxable year, it may nevertheless  qualify
as a REIT for such year by obtaining relief under certain  provisions of Section
856 of the Code.  Such  provisions  would allow the Company to preserve its REIT
qualifications if (i) the failure to meet such tests was due to reasonable cause
and not due to willful  neglect,  (ii) the  Company  attaches a schedule  of the
sources of its income to its tax return, and (iii) any incorrect  information on
the  schedule  was not due to fraud with  intent to evade  tax.  There can be no
assurance,  however,  that the Company would be entitled to the benefit of these
relief provisions in all  circumstances.  As discussed above in "Taxation of the
Company--General", even if these relief provisions apply, a tax would be imposed
with respect to the excess net income.

     ASSET TESTS. To maintain its status as a REIT the Company,  at the close of
each  quarter  of its  taxable  year,  also must  satisfy  the  following  three
asset-related tests:

     (i) At  least  75% of the  value  of the  Company's  total  assets  must be
     represented by interests in real estate assets,  shares in cash, cash items
     and  government  securities  (as well as certain  temporary  investments in
     stock or debt instruments purchased with the proceeds of new capital issued
     by the Company).

     (ii) No more than 25% of the Company's  total assets may be  represented by
     securities other than those in the class described in (i), above.

     (iii) With respect to the investments described in (ii) above, the value of
     any one issuer's  securities  owned by the Company may not exceed 5% of the
     value of the Company's total assets,  and the Company may not own more than
     10%  of  any  one  issuer's  outstanding  voting  securities.  The  Clinton
     Administration's  1999 budget  proposal  would prohibit a REIT from holding
     more than 10% of the  outstanding  stock of any one issuer,  determined  by
     either vote or value. This proposal is not part of the 1998 Act.

     In applying these asset-related tests the Company will be deemed to own its
proportionate share of all of the assets of the Operating Partnerships. Upon the
consummation  of the  Berg  Acquisition,  more  than  75% of  the  value  of the
Operating Partnerships' assets will qualify as "real estate assets."

     Having met the asset tests at the close of any  quarter,  the Company  will
not forfeit  its REIT  status by failing to satisfy  these tests at the end of a
later quarter solely due to  fluctuations in asset values.  Furthermore,  should
the  Company  fail to satisfy  the asset  tests  because of its  acquisition  of
securities or other property during a quarter,  the Company can be cured of such
failure by disposing of a sufficient  amount of  nonqualifying  assets within 30
days after the close of that quarter.  The Company intends to maintain  adequate
records of the value of its assets to ensure  compliance with the  asset-related
tests,  and to take such  other  action  within  30-days  after the close of any
quarter as may be required to cure any noncompliance.

     ANNUAL  DISTRIBUTION  REQUIREMENTS.  In order  to  qualify  as a REIT,  the
Company must distribute  dividends  (other than capital gains  dividends) to its
shareholders  in an  amount  at least  equal  to:  (A) the sum of (i) 95% of the
Company's  "REIT taxable income"  (computed  without regard to deduction for the
dividends  paid and by  excluding  any net  capital  gain),  and (ii) 95% of the
excess of the net income,  if any, from  foreclosure  property (in excess of the
special tax imposed on income from foreclosure  property);  minus (B) the sum of
certain items of "noncash  income".  Such  dividends must be paid in the taxable
year to which they relate,  or in the following  taxable year if declared before
the Company  timely files its tax return for such year, and if paid on or before
the first regular  dividend payment after such  declaration.  To the extent that
the Company does not  distribute  all of its net capital gain or  distributes at
least 95%, but less than 100%, of its REIT taxable income, as adjusted,  it will
be  subject to tax on the  undistributed  amount of its REIT  taxable  income at
regular  ordinary  and capital  gains  corporate  tax rates.  For the  Company's
taxable year beginning on January 1, 1998 and for all taxable years  thereafter,
undistributed  capital  gains may be so  designated  by the  Company and in such
event will be includible in the income of the holders of shares of Common Stock.
If the Company makes that election,  shareholders will be treated as having paid
the capital gains tax imposed on the Company on the designated amounts including
in their income as  long-term  capital  gains.  Such  shareholders  would get an
increase  in the basis for income  recognized  and a decrease in their basis for
taxes paid by the Company.  Additionally,  if the Company fails to distribute at
least the sum of (i) 85% of its REIT ordinary  income for such year, (ii) 95% of
its REIT capital gain income for such year, and (iii) any undistributed  taxable
income from prior  periods,  during  each  calendar  year the  Company  would be
subject to a 4% excise tax on the excess of such requied  distribution  over the
amounts actually distributed.

                                    -111-
<PAGE>

     The  Company's  REIT  taxable  income will consist  almost  entirely of the
Company's  distributive  share of the income of the Operating Partnerships.  The
Company  expects  generally to have adequate cash and cash  equivalents to allow
liquid assets to satisfy such distribution requirements.  The Company intends to
make timely  distributions  sufficient  to satisfy the REIT annual  distribution
requirements.

     Nevertheless,  on occasion  the Company  may lack  sufficient  cash or cash
equivalents to make timely dividend distributions in the required amounts either
because its share of the Operating Partnerships' cash flow for a particular year
is inadequate or because of timing differences  between the Company's receipt of
income and payment of deductible expenses,  and the inclusion of such income and
the deduction of such expenses in determining the Company's REIT taxable income.
Upon the  occurrence  of  these  events,  in order to meet the 95%  distribution
requirements,  the Company may find it necessary to arrange for  short-term,  or
possibly long-term,  borrowings or to pay dividends in the form of taxable stock
dividends.

     Certain provisions of the Code may permit the Company to remedy its failure
to meet the distribution  requirements for a taxable year by paying  "deficiency
dividends"  to  shareholders  in a later  year,  which  may be  included  in the
Company's  deduction for dividends  paid for the earlier year.  The Company then
could avoid being subjected to tax on the amounts so  distributed,  although the
Company would be required to pay interest on the amount of the  deduction  taken
for the deficiency dividends.

     LOSS OF REIT QUALIFICATION. If the Company fails to qualify for taxation as
a REIT in any taxable year, and the relief  provisions do not apply, the Company
will be subject to tax (including any applicable  corporate  alternative minimum
tax)  on its  taxable  income  at  regular  corporate  rates.  Distributions  to
shareholders  in any year in which  the  Company  fails to  qualify  will not be
deductible  by the Company and need not be made.  Upon such  failure to qualify,
all  distributions to shareholders  will, to the extent of the Company's current
and  accumulated  earnings  and  profits,  be taxable  as  ordinary  income.  In
addition,  subject to certain  limitations of the Code,  such  distributions  to
corporate  distributees  may be eligible for the dividends  received  deduction.
Unless entitled to relief under specific statutory provisions,  the Company also
will be  disqualified  from  taxation  as a REIT  for  the  four  taxable  years
following  the year during which  qualification  was lost. It is not possible to
state  whether  in all  circumstances  the  Company  would be  entitled  to such
statutory relief.

TAXATION OF UNITED STATES SHAREHOLDERS

     GENERALLY.  As used herein,  the term "United States  Shareholder"  means a
holder of shares who is an individual who is a citizen or resident of the United
States;  a corporation,  partnership or other entity created or organized in, or
under the laws of, the United States or any state; an estate the income of which
from sources  without the United States is includible in gross income for United
States  federal  income  tax  purposes  regardless  of  whether  such  income is
effectively  connected  with the  conduct of a trade or  business  in the United
States;  a trust the primary  supervision  over the  administration  of which is
exercisable  by a court  within the United  States and having one or more United
States  fiduciaries with authority to control all substantial  decisions of such
trust;  and any other  person  whose  income or gain in  respect of the stock is
effectively connected with the conduct of a United States trade or business.

     As long as the  Company  qualifies  as a  REIT,  distributions  made to the
Company's United States Shareholders out of current or accumulated  earnings and
profits (and not designated as capital gains  dividends) will be treated by them
as ordinary income and will not be eligible for the dividends received deduction
for  corporations.  Distributions  designated as capital gains dividends will be
taxed as long-term capital gains (to the extent they do not exceed the Company's
actual net capital gain for the taxable year)  without  regard to the period for
which the United  States  Shareholder  has held its stock.  Pursuant  to Section
291(d) of the Code corporate  shareholders may be required to treat up to 20% of
certain capital gain dividends as ordinary income.

     On November 10, 1997, the IRS issued Notice 97-64, which provides generally
that a REIT may classify portions of its designated capital gain dividend as (i)
a 20% rate gain distribution  (which would be taxed as long-term capital gain in
the 20% group), (ii) an unrecaptured Section 1250 gain distribution (which would
be taxed as long-term  capital gain in the 25% group),  or (iii) a 28% rate gain
distribution  (which would be taxed as long-term capital gain in the 28% group).
(If no designation is made, the entire  designated  capital gain divided will be
treated as a 28% rate gain  distribution.  For a discussion  of the 20%, 25% and
28% tax rates  applicable to individuals,  see "1997 Act Changes to Capital Gain
Taxation" below).  IRS Notice 97-64 also provides that a REIT must determine the
maximum amounts that it may designate as 20% and 25% rate capital gain dividends
by performing the

                                    -112-
<PAGE>

computation  required  by the  Code  as if the  REIT  were an  individual  whose
ordinary  income were subject to a marginal tax rate of at least 28%. The Notice
further  provides that  designations  made by the REIT will be effective only to
the extent that they comply with  Revenue  Ruling  89-91,  which  requires  that
distributions made to different classes of shares be composed proportionately of
dividends of a particular type.

     Distributions that exceed current and accumulated earnings and profits will
not be taxable to a United  States  Shareholder  to the extent  that they do not
exceed the adjusted basis of the  shareholder's  shares,  but rather will reduce
the  shareholder's  adjusted  basis  in the  shares.  To the  extent  that  such
distributions  exceed a shareholder's  adjusted basis in its shares they will be
included in income as gain  realized  from the sale of the shares,  assuming the
shares are a capital  asset in the hands of the  shareholder.  In addition,  any
dividend  declared by the  Company in October,  November or December of any year
payable to a United States Shareholder of record on a specified date in any such
month  shall  be  treated  as  both  paid by the  Company  and  received  by the
shareholder on December 31 of such year,  provided that the dividend is actually
paid by the Company during January of the following calendar year. United States
Shareholders  may not  include in their  individual  income tax  returns any net
operating losses or capital losses of the Company.

     The Company  will be treated as having  sufficient  earnings and profits to
treat as a dividend any distribution by the Company up to the amount required to
be distributed in order to avoid imposition of the 4% excise tax discussed under
"Taxation of the Company--General" and "Annual Distribution Requirements" above.
As a result,  shareholders may be required to treat as taxable dividends certain
distributions  which  would  otherwise  result in a tax-free  return of capital.
Furthermore,  any  "deficiency  dividend"  will be treated as a  "dividend"  (an
ordinary dividend or a capital gain dividend, as the case may be), regardless of
the Company's earnings and profits.

     United States  Shareholders may not include in their individual  income tax
returns any net operating losses or capital losses of the Company. Instead, such
losses would be carried over by the Company for potential  offset against future
income (subject to certain  limitations).  Distributions made by the Company and
gain arising from the sale or exchange by a United States  Shareholder of shares
will not be treated as passive activity income, and, as a result,  United States
Shareholders  generally will not be able to apply any "passive  losses"  against
such  income  or gain.  In  addition,  taxable  distributions  from the  Company
generally  will be treated as investment  income for purposes of the  investment
interest  limitations.  Capital  gain  dividends  and  capital  gains  from  the
disposition of shares (including  distributions  treated as such), however, will
be treated as investment income only if the United States Shareholder so elects,
in which case such capital  gains will be taxed at ordinary  income  rates.  The
Company will notify United States  Shareholders after the close of the Company's
taxable year as to the portions of distributions  attributable to that year that
constitute ordinary income, return of capital and capital gain.

     In general, any loss realized upon a sale or exchange of shares by a United
States  Shareholder  who has held  such  shares  for six  months or less will be
treated as a long-term or mid-term  capital loss to the extent of capital  gains
dividends  received by such  shareholder  from the Company  with respect to such
shares which were classified as long-term or mid-term capital gains.

     RECENT CHANGES TO CAPITAL GAIN TAXATION.  The 1997 Act altered the taxation
of capital gain income. Under the 1997 Act, individuals, trusts and estates that
hold certain investments for more than eighteen months may be taxed at a maximum
long-term capital gain rate of 20% on the sale or exchange of those investments.
Individuals,  trusts and estates that hold certain assets for more than one year
but not more than  eighteen  months may be taxed at a maximum  mid-term  capital
gain rate of 28% on the sale or exchange of those investments. The 1997 Act also
established  a maximum  rate of 25% for  "unrecaptured  Section  1250  gain" for
individuals,  trusts and estates,  special rules for "qualified five-year gain",
and other  changes  to prior  law.  The 1997 Act  allowed  the IRS to  prescribe
regulations  on how the 1997 Act's new capital gain rates will apply to sales of
capital assets by "pass-through entities",  which include REITs, and to sales of
interests in "pass-through entities".  Under the 1998 Act, the long-term capital
gain rates  apply to capital  assets held more than one year,  and the  mid-term
holding  period has been  eliminated  for sales or exchanges  after December 31,
1997. Shareholders are urged to consult with their own tax advisors with respect
to the new rules contained in the 1997 Act and the 1998 Act.

TAXATION OF TAX-EXEMPT SHAREHOLDERS

     Distributions  from the Company to certain  tax-exempt  employees'  pension
trusts or other domestic tax-exempt  Shareholders will not constitute "unrelated
business  taxable  income" unless such a shareholder  has borrowed to acquire or
carry its stock of the Company or the shares are used by such  shareholder in an
unrelated  trade or business.  For taxable years  beginning  after  December 31,
1993, qualified trusts that hold more than 10%

                                    -113-
<PAGE>

of the shares of the Common Stock may under certain circumstances be required to
treat a certain  percentage of dividends as unrelated business taxable income if
the Company is "predominantly  held" by qualified trusts. For these purposes,  a
qualified trust is any trust defined under Section 401(a) of the Code and exempt
from tax under Section 501(a) of the Code.  The Company would be  "predominantly
held" if one or more qualified  trusts,  each owning more than 10% of the shares
of Common  Stock were to hold more than 50% of the shares of Common Stock in the
aggregate. In such a circumstance,  any qualified trust that owned more than 10%
of the shares of Common  Stock might be  required to treat a certain  portion of
the dividends paid as unrelated business taxable income.

TAXATION OF FOREIGN SHAREHOLDERS

     The rules  governing  United States federal income  taxation of nonresident
alien individuals, foreign corporations,  foreign partnerships and other foreign
shareholders (collectively,  "Foreign Shareholders") are complex, and no attempt
will be made herein to provide  more than a summary of such  rules.  PROSPECTIVE
FOREIGN SHAREHOLDERS SHOULD CONSULT WITH THEIR OWN TAX ADVISORS TO DETERMINE THE
IMPACT OF FEDERAL,  STATE AND LOCAL INCOME TAX LAWS WITH REGARD TO AN INVESTMENT
IN THE COMPANY, INCLUDING ANY REPORTING REQUIREMENTS.

     Distributions  by the Company that are not  attributable to gain from sales
or exchanges by the Company of United  States real  property  interests  and not
designated  by the  Company  as  capital  gains  dividends  will be  treated  as
dividends of ordinary  income to the extent that they are made out of current or
accumulated earnings and profits of the Company.  Such distributions  ordinarily
will be subject  to a  withholding  tax equal to 30% of the gross  amount of the
distribution, unless an applicable tax treaty reduces or eliminates that tax. If
income from the  investment  in the shares is treated as  effectively  connected
with  the  conduct  by the  Foreign  Shareholder  of a  United  States  trade or
business, however, the Foreign Shareholder generally will be subject to a tax at
graduated rates in the same manner as United States  Shareholders are taxed with
respect to such  dividends (and the income may also be subject to the 30% branch
profits tax in the case of a Foreign Shareholder that is a foreign corporation).
The Company will  withhold  United  States  income tax at the rate of 30% on the
gross amount of any such  dividends made to a Foreign  Shareholder  unless (i) a
lower treaty rate  applies,  or (ii) the Foreign  Shareholder  files an IRS Form
4224 with the Company  certifying that the investment to which the  distribution
relates is effectively  connected with a United States trade or business of such
Foreign  Shareholder.  Lower treaty rates  applicable to dividend income may not
necessarily apply to dividends from a REIT such as the Company, however.

     Distributions  in excess of current or accumulated  earnings and profits of
the Company will not be taxable to a Foreign Shareholder to the extent that they
do not exceed the adjusted basis of the Foreign Shareholder's shares, but rather
will reduce the adjusted basis of a Foreign  Shareholder's shares. To the extent
that such  distributions  exceed the adjusted  basis of a Foreign  Shareholder's
shares,  they will give rise to gain from the sale or exchange of its stock, the
tax treatment of which is described  below. As a result of a legislative  change
made by the Small  Business  Job  Protection  Act of 1996,  it appears  that the
Company  will be required to withhold 10% of any  distribution  in excess of the
Company's current and accumulated earnings and profits.  Consequently,  although
the Company  intends to  withhold  at a rate of 30% on the entire  amount of any
distribution (or a lower applicable treaty rate), to the extent that the Company
does not do so, any portion of a  distribution  not subject to  withholding at a
rate of 30% (or a lower  applicable  treaty rate) will be subject to withholding
at a rate of 10%.  However,  the Foreign  Shareholder  may seek a refund of such
amounts from the IRS if it is  subsequently  determined  that such  distribution
was, in fact,  in excess of current or  accumulated  earnings and profits of the
Company,  and the amount  withheld  exceeded  the Foreign  Shareholder's  United
States tax liability, if any, with respect to the distribution.

     Distributions   that  are   designated  by  the  Company  at  the  time  of
distribution  as capital  gains  dividends  (other than those  arising  from the
disposition  of a United States real property  interest)  generally  will not be
subject  to  taxation,  unless  (i)  investment  in the  shares  is  effectively
connected  with the Foreign  Shareholder's  United States trade or business,  in
which case the  Foreign  Shareholder  will be subject to the same  treatment  as
United  States  Shareholders  with  respect to such gain  (except that a Foreign
Shareholder that is a foreign  corporation may also be subject to the 30% branch
profits tax), or (ii) the Foreign  Shareholder is a nonresident alien individual
who was  present in the United  States for 183 days or more  during the  taxable
year and has a tax home in the  United  States,  in which  case the  nonresident
alien individual will be subject to a 30% tax on the capital gains.

                                    -114-
<PAGE>

     For any year in which the Company qualifies as a REIT,  distributions  that
are  attributable  to gain from the sale or  exchange by the Company of a United
States real property  interest will be taxed to a Foreign  Shareholder under the
provisions  of  the  Foreign  Investment  in  Real  Property  Tax  Act  of  1980
("FIRPTA"). Under FIRPTA, these distributions are taxed to a Foreign Shareholder
as if such  gain  were  effectively  connected  with a  United  States  trade or
business conducted by the Foreign  Shareholder.  Foreign Shareholders would thus
be taxed at the same capital gain rates applicable to United States Shareholders
(subject to applicable alternative minimum tax and a special alternative minimum
tax in the case of nonresident alien individuals).  Also,  distributions subject
to FIRPTA may be subject to a 30% branch  profits  tax in the hands of a foreign
corporate shareholder not entitled to treaty exemption.  The Company is required
by applicable IRS regulations to withhold 35% of any distribution  that could be
designated by the Company as a capital gain dividend.  This amount is creditable
against the Foreign Shareholder's FIRPTA tax liability.

     If the Company is a "domestically-controlled  REIT," a sale of Common Stock
by a  Foreign  Shareholder  generally  will  not be  subject  to  United  States
taxation.  A  "domestically-controlled  REIT" is a REIT in  which,  at all times
during a particular  testing period  (generally five years preceding the sale in
issue),  less than 50% of the value of the REIT's  shares are held  directly  or
indirectly   (taking   into   consideration   attribution   rules)  by   Foreign
Shareholders. Because the Common Stock will be publicly traded, no assurance can
be given  that the  Company  will  constitute  a  domestically-controlled  REIT.
Notwithstanding  the  foregoing,  capital  gain  from  the  sale of  stock  of a
domestically-controlled  REIT not subject to FIRPTA will be taxable to a Foreign
Shareholder (under rules generally  applicable to United States Shareholders) if
such person is in the United States for 183 days or more during the taxable year
of disposition and certain other conditions apply.

     If the  Company is not a  domestically-controlled  REIT,  whether a sale of
Common Stock would be subject to tax under  FIRPTA as a sale of a United  States
real  property  interest  would depend on whether the Common Stock is "regularly
traded"  (as  defined by  applicable  Treasury  Regulations)  on an  established
securities  market  (e.g.,  the AMEX and the PCX,  on which the Common  Stock is
listed) and whether the selling shareholder held,  directly or indirectly,  more
than 5% of the Common Stock during the  five-year  period  ending on the date of
disposition.  Arguably,  the applicable Treasury Regulations defining "regularly
traded" for this  purpose  provide  that the shares of Common  Stock will not be
"regularly  traded" for any calendar  quarter  during which 100 or fewer persons
(treating related persons as one person) in the aggregate own 50% or more of the
shares of Common Stock. If this  interpretation is correct,  and the Company did
not at the time constitute a domestically-controlled REIT, a Foreign Shareholder
(without regard to its ownership  percentage of Common Stock) will be subject to
federal  income  tax  with  respect  to  gain  realized  on any  sale  or  other
disposition  of Common Stock that occurs within a calendar  quarter during which
50% or more of the  Common  Stock  is so  owned.  If the gain on the sale of the
Common Stock is subject to taxation under FIRPTA,  the Foreign  Shareholder will
be subject to the same treatment as a United States  Shareholder with respect to
such  gain  (subject  to  applicable  alternative  minimum  tax  and  a  special
alternative  minimum tax in the case of nonresident alien  individuals).  In any
event,  a  purchaser  of Common  Stock  from a Foreign  Shareholder  will not be
required under FIRPTA to withhold on the purchase price if the purchased  Common
Stock is  "regularly  traded"  on an  established  securities  market  or if the
Company is a domestically-controlled REIT. Otherwise, under FIRPTA the purchaser
of Common Stock may be required to withhold 10% of the purchase  price and remit
such amount to the IRS.

INFORMATION REPORTING REQUIREMENTS AND BACKUP WITHHOLDING TAX

     The  Company  will  report to its  shareholders  and the IRS the  amount of
dividends  paid or deemed paid during each calendar  year, and the amount of tax
withheld, if any.

     UNITED  STATES  SHAREHOLDERS.  Under certain  circumstances,  United States
Shareholders  owning Common Stock may be subject to backup withholding at a rate
of 31% on payments  made with respect to, or cash proceeds of a sale or exchange
of, Common Stock.  Backup  withholding  will apply only if the  shareholder  (i)
fails to furnish the Company with its  Taxpayer  Identification  Number  ("TIN")
which, for an individual,  would be his Social Security  Number,  (ii) furnishes
the  Company  with an  incorrect  TIN,  (iii) is notified by the IRS that it has
failed  properly to report  payments of interest  and  dividends,  or (iv) under
certain  circumstances,  fails to certify, under penalty of perjury, that it has
furnished a correct TIN and has not been  notified by the IRS that it is subject
to backup  withholding  for failure to report  interest and  dividend  payments.
Backup  withholding  will not apply  with  respect to  payments  made to certain
exempt recipients, such as tax-exempt organizations.  United States Shareholders
should  consult  their  own  tax  advisors  regarding  their  qualification  for
exemption  from backup  withholding  and the  procedure  for  obtaining  such an
exemption. Backup withholding is not an additional tax. Rather, the amount of

                                     -115-
<PAGE>

any backup  withholding with respect to a payment to a United States Shareholder
will be allowed as a credit  against  such United  States  Shareholder's  United
States  federal  income  tax  liability  and  may  entitle  such  United  States
Shareholder to a refund,  provided that the required information is furnished to
the IRS.

     FOREIGN SHAREHOLDERS. Additional issues may arise pertaining to information
reporting  and backup  withholding  with  respect to Foreign  Shareholders,  and
Foreign  Shareholders should consult their tax advisors with respect to any such
information  reporting and backup withholding  requirements.  Backup withholding
with respect to Foreign  Shareholders  is not an  additional  tax.  Rather,  the
amount  of any  backup  withholding  with  respect  to a  payment  to a  Foreign
Shareholder will be allowed as a credit against any United States federal income
tax  liability  of  such  Foreign  Shareholder.  If  withholding  results  in an
overpayment  of taxes,  a refund  may be  obtained  provided  that the  required
information is furnished to the IRS.

     The United States Treasury has recently finalized regulations regarding the
withholding and information  reporting rules discussed above. In general,  these
regulations do not alter the substantive  withholding and information  reporting
requirements,  but unify  certification  procedures  and forms and  clarify  and
modify  reliance  standards.  These  regulations  generally  are  effective  for
payments  made after  December 31, 1999,  subject to certain  transition  rules.
Valid  withholding  certificates that are held on December 31, 1999, will remain
valid until the earlier of December 31, 2000,  or the date of  expiration of the
certificate under rules currently in effect (unless otherwise invalidated due to
changes in the circumstances of the person whose name is on such certificate). A
Foreign  Shareholder  should consult its own advisor regarding the effect of the
new Treasury Regulations.

TAX ASPECTS OF THE OPERATING PARTNERSHIPS

     GENERAL.  Substantially  all of the  Company's  investments  will  be  held
indirectly  through  the  Operating Partnerships,  which  in turn  will  own the
Properties.  In general,  partnerships are "pass-through"  entities that are not
subject to federal income tax.  Instead,  partners  receive an allocation of the
items of income,  gain,  loss,  deduction and credit of a  partnership,  and are
potentially subject to tax on their distributive shares thereof,  without regard
to  whether  the  partners   actually  receive  a  cash  distribution  from  the
partnership.  The Company will include in its income its share of the  foregoing
partnership  items for  purposes  of the various  REIT  income  tests and in the
computation of its REIT taxable income.  See:  "Partnership  Allocations" below.
Moreover,  for  purposes of the REIT asset  tests,  the Company will include its
proportionate  share of assets held  directly  or  indirectly  by the  Operating
Partnerships. See "Taxation of the Company".

     ENTITY  CLASSIFICATION.  If the  Operating Partnerships  were treated as an
association  taxable as a corporation  instead of as a partnership,  it would be
taxable as a corporation  and therefore  subject to an  entity-level  tax on its
income.  In this event, the character of the Company's assets and items of gross
income  would  change  and  would  preclude  the  Company  from  satisfying  the
asset-related   tests  and  the   income   tests   (see   "FEDERAL   INCOME  TAX
CONSIDERATIONS"  --"Taxation of the Company--Asset  Tests" and " Income Tests"),
which in turn would prevent the Company from  qualifying as a REIT. See "Failure
to Qualify"  above for a discussion  of the effect of the  Company's  failure to
meet such tests for a taxable year.

     The  Operating  Partnerships  has not  requested,  nor  does it  intend  to
request,  a ruling  from the IRS that it will be  treated as a  partnership  for
federal  income tax  purposes.  Instead,  at the closing of the  Reincorporation
Merger,  Graham & James LLP will deliver an opinion to the effect that, based on
the  provisions  of the Operating  Partnership  Agreement,  and certain  factual
assumptions  and  representations   described  in  the  opinion,  the  Operating
Partnerships  will be treated as a partnership  for federal income tax purposes.
Unlike a private letter ruling, an opinion of counsel is not binding on the IRS,
and no assurance  can be given that the IRS will not challenge the status of the
Operating Partnerships as a partnership for federal income tax purposes. If such
challenges  were  sustained by a court,  the  Partnership  would be treated as a
corporation for federal income tax purposes.

     PARTNERSHIP ALLOCATIONS. Although the provisions of a partnership agreement
generally  determine the partners'  respective  allocations  of income and loss,
such  allocations  will be  disregarded  for tax  purposes  if they do not  have
"substantial  economic  effect" under the  requirements of Section 704(b) of the
Code and the Treasury Regulations  promulgated  thereunder.  If an allocation is
not  recognized  for  federal  income  tax  purposes,  the item  subject  to the
allocation will be reallocated in accordance with the partners' interests in the
partnership,  which will be  determined  by taking into account all of the facts
and  circumstances  relating to the economic  arrangement  of the partners  with
respect to such item. The allocations of taxable income and loss by the

                                    -116-
<PAGE>


Operating Partnerships  are intended to comply with the  requirements of Section
704(b) of the Code and the Treasury Regulations promulgated thereunder.

     TAX ALLOCATIONS WITH RESPECT TO CONTRIBUTED  PROPERTIES.  Section 704(c) of
the  Code  requires  all  income,  gain,  loss  and  deduction  attributable  to
appreciated  or  depreciated  property that is  contributed  to a partnership in
exchange for an interest in the  partnership  to be allocated for federal income
tax purposes in a manner such that the  contributor  is charged with or benefits
from the unrealized gain or unrealized loss inherent in the property at the time
of the  contribution.  The amount of such  unrealized gain or unrealized loss is
generally  equal  to  the  difference  between  the  fair  market  value  of the
contributed  property at the time of contribution  and the adjusted tax basis of
such  property  at the time of  contribution  (a  "Book-Tax  Difference").  Such
allocations  are made solely for federal  income tax  purposes and do not affect
the book capital accounts or other economic arrangements among the partners. The
Partnership Agreement generally requires such allocations to be made in a manner
consistent with the provisions of Section 704(c) of the Code.

     Treasury  Regulations under Section 704(c) of the Code provide partnerships
with a choice of  several  methods  of  accounting  for a  Book-Tax  Difference,
including  retention  of the  "traditional  method" or the  election  of certain
alternative  methods  which would  permit any  distortions  caused by a Book-Tax
Difference  to be entirely  rectified  on an annual  basis or with  respect to a
specific taxable transaction such as a sale. Based on the foregoing, in general,
if any  asset  contributed  to or  revalued  by the  Operating  Partnerships  is
determined  to have a fair market  value which is greater  than its adjusted tax
basis,  certain partners of the Operating  Partnerships  will be allocated lower
amounts  of   depreciation   deductions   for  tax  purposes  by  the  Operating
Partnerships  and increased  taxable income and gain on sale.  Such  allocations
will tend to eliminate  the Book-Tax  Difference  over the life of the Operating
Partnerships.  However,  the special  allocation  rules of Section 704(c) of the
Code do not always entirely  rectify the Book-Tax  Difference on an annual basis
or with respect to a specific  transaction such as a sale. Thus, the Company may
be allocated  lower  depreciation  and other  deductions,  and possibly  greater
amounts of taxable income in the event of a sale of contributed assets, and such
amounts may be in excess of the  economic or book  income  allocated  to it as a
result of such sale.  Such an  allocation  might cause the Company to  recognize
taxable  income in excess of cash  proceeds,  which might  adversely  affect the
Company's  ability  to  comply  with the  REIT  distribution  requirements.  See
"--Requirements for Qualification--Annual Distribution Requirements".

     Any  property  purchased  or  constructed  by  the  Operating  Partnerships
subsequent to the Berg  Acquisition will initially have a tax basis equal to its
cost, and Section 704(c) of the Code will not apply.  Depreciation  with respect
to such  property  will be allocated  for book and tax purposes pro rata to each
partner.

     Upon the  disposition of any Properties  with a Book-Tax  Difference for an
amount  greater than the adjusted tax basis,  book gain will be allocated to the
Limited Partners and the Company to the extent of any prior special  allocations
of depreciation with respect to such Properties,  then pro rata to each Partner.
In addition,  tax gain with respect to such  Properties will be allocated to the
Limited  Partners  to the  extent of the  remaining  Book-Tax  Difference,  then
pro-rata to each partner. On any subsequently  purchased property,  gain for tax
and book purposes will be allocated pro rata to each Partner.

     BASIS IN  PARTNERSHIP  INTEREST.  The  Company's  adjusted tax basis in its
interest in the Operating Partnerships generally (i) will be equal to the amount
of cash  and the  basis  of any  other  property  contributed  to the  Operating
Partnerships  by the Company,  (ii) will be increased by its allocable  share of
(a)  the  Operating  Partnerships'  income,  and  (b)  the  indebtedness  of the
Operating  Partnerships,  and (iii) will be reduced,  but not below zero, by the
Company's allocable share of (a) the Operating  Partnerships' losses and (b) the
amount of cash distributed to the Company by the Operating Partnerships,  and by
constructive  distributions resulting from a reduction in the Company's share of
indebtedness of the Operating Partnerships.

     If the  allocation  of the  Company's  distributive  share of the Operating
Partnerships'  loss  will  reduce  the  adjusted  tax  basis  of  the  Company's
partnership  interest in the Operating  Partnerships below zero, the recognition
of such loss will be deferred  until such time as the  recognition  of such loss
would not reduce the Company's adjusted tax basis below zero. To the extent that
the  Operating  Partnerships'  distributions,  or any decrease in the  Company's
share  of the  nonrecourse  indebtedness  of  the  Operating Partnerships  (such
decreases  being  considered a constructive  cash  distribution to the partners)
exceeds the Company's  adjusted tax basis,  such  distributions  will constitute
taxable   income  to  the  Company.   Such  taxable   income  will  normally  be
characterized  as a capital gain, and if the Company's  partnership  interest in
the Operating Partnerships  has been held for longer than the long-term  capital
gain holding period, the distribution will constitute a long-term capital gain.

                                    -117-
<PAGE>

     SALE OF THE  OPERATING  PARTNERSHIPS'  PROPERTY.  Any gain  realized by the
Operating Partnerships  on the sale of property held for more than one year will
generally be mid-term  capital  gain,  long-term  capital  gain or  unrecaptured
Section  1250  gain,  except  for any  portion  of such gain that is  treated as
depreciation or cost recovery recapture,  in accordance with the rules described
above.  See  "--Taxation  of United  States  Shareholders--1997  Act  Changes to
Capital  Gain  Taxation."  The  Operating   Partnerships  intends  to  hold  the
Properties for investment  with a view to long-term  appreciation,  to engage in
the business of acquiring,  developing, owning, and operating the Properties and
additional properties,  and to sell a Property when such sale is consistent with
the Operating Partnerships' investment objectives. See "POLICIES WITH RESPECT TO
CERTAIN ACTIVITIES".

FEDERAL INCOME TAX CONSEQUENCES OF THE REINCORPORATION MERGER.

     The Company has been advised by Graham & James LLP that, for federal income
tax purposes,  no gain or loss will be recognized by the holders of Common Stock
or options  to  purchase  Common  Stock as a result of the  consummation  of the
Reincorporation  Merger. Each holder of Common Stock will have the same basis in
the New Common Stock received pursuant to the  Reincorporation  Merger as he had
in the Common Stock held immediately prior to the  Reincorporation  Merger,  and
his holding  period with respect to the New Common Stock will include the period
during which he held the corresponding Common Stock, so long as the Common Stock
was held as a capital asset at the time of consummation  of the  Reincorporation
Merger.

     The  Company  has also been  advised by Graham & James LLP that the Company
will not recognize  gain or loss for federal  income tax purposes as a result of
the Reincorporation  Merger, and that Mission West-Maryland will succeed without
adjustment  to the tax  attributes  of the  Company.  The  Company is  currently
subject to state income taxation in California. If the Reincorporation Merger is
approved, Mission West-Maryland may be subject to California state income tax.

OTHER TAX CONSEQUENCES

     The Company and its  shareholders may be subject to state or local taxation
in various  state or local  jurisdictions,  including  those in which it or they
transact  business or reside.  The state and local tax  treatment of the Company
and its  shareholders  may not  conform to the federal  income tax  consequences
discussed above. Consequently, prospective shareholders should consult their own
tax advisors  regarding  the effect of state and local tax laws on an investment
in the Company.

                              ERISA CONSIDERATIONS

GENERAL

     In  evaluating  the effect of the UPREIT  Transactions,  a  fiduciary  of a
qualified  profit-sharing,  pension or stock  bonus  plan,  including a plan for
self-employed individuals and their employees or any other employee benefit plan
(a "Plan")  subject to the Employee  Retirement  Income Security Act of 1974, as
amended ("ERISA"),  should consider (a) whether the ownership of Common Stock is
in accordance  with the  documents  and  instruments  governing  such Plan;  (b)
whether  the  ownership  of  Common  Stock is  consistent  with the  fiduciary's
responsibilities  and satisfies the  requirements  of Part 4 of Title I of ERISA
(where  applicable)  and,  in  particular,  the  diversification,  prudence  and
liquidity  requirements of Section 404 of ERISA;  (c) the effect in the unlikely
event that the Company's  assets are treated as assets of the Plan;  and (d) the
need to value the assets of the Plan annually.

     The fiduciary investment  considerations summarized below provide a general
discussion  that does not include all the  fiduciary  investment  considerations
relevant to a Plan. This summary is based on the current provisions of ERISA and
the Code and regulations and rulings thereunder and both of which may be changed
(perhaps  adversely  and  with  retroactive   effect)  by  future   legislative,
administrative or judicial  actions.  This discussion should not be construed as
legal advice and prospective  purchasers of Common Stock should consult with and
rely upon their own advisors in  evaluating  these matters in light of their own
personal circumstances.

PLAN ASSETS REGULATIONS

     Under Department of Labor ("DOL")  regulations  determining the assets of a
Plan for  purposes of ERISA and the related  prohibited  transaction  excise tax
provisions  of the Code (the  "Plan  Asset  Regulation"),  when a Plan  makes an
equity  investment in another entity,  the underlying assets of that entity will
not  be   considered   assets  of  the  Plan  if  the  equity   interest   is  a
"publicly-offered security."

     For purposes of the Plan Asset Regulation, a "publicly-offered security" is
a security that is (a) "freely  transferable," (b) part of a class of securities
that is "widely held," and (C) part of a class of securities  that is registered
under  section  12(b) or  12(g)  of the  Securities  Exchange  Act of 1934  (the
"Exchange  Act").  The Common Stock has been registered under the Securities Act
and the Exchange Act of 1934.

     The Plan Asset Regulation provides that a security is "widely held" only if
it is a part of the class of securities  that is owned by 100 or more  investors
independent  of the issuer and of one  another.  A security  will not fail to be
"widely  held"  because  the number of  independent  investors  falls  below 100
subsequent  to the  offering  as a result of events  beyond  the  control of the
issuer.  The Company  expects the Common Stock to remain  "widely held" upon the
completion of the UPREIT Transactions.

     The Plan Asset  Regulation  provides  that  whether a  security  is "freely
transferable"  is a factual  question to be  determined  on the basis of all the
relevant facts and  circumstances.  The Plan Asset  Regulation  further provides
that when a security is part of an offering in which the minimum  investment  is
$10,000 or less, as is the case with the offering of the Common  Stock,  certain
restrictions  ordinarily will not, alone or in  combination,  affect the finding
that such securities are "freely  transferable."  The Company  believes that the
restrictions  imposed  under the Charter on the transfer of the New Common Stock
are limited to the restrictions on transfer  generally  permitted under the Plan
Asset  Regulation  and are not likely to result in the failure of the New Common
Stock to be "freely  transferable."  However, no assurance can be given that the
DOL will not reach a contrary conclusion.

     Therefore,  the Company  believes  that the Common Stock and the New Common
Stock should be treated as "publicly-offered  securities",  under the Plan Asset
Regulation and,  accordingly,  that the underlying  assets of the Company should
not be considered to be assets of any Plan investing in the Common Stock.

GENERAL ERISA REQUIREMENTS

     ERISA  generally  requires  that the  assets of a Plan be held in trust and
that the trustee,  or an investment manager (within the meaning of Section 3(38)
of ERISA),  have  exclusive  authority and  discretion to manage and control the
assets of the Plan.  As  discussed  above,  under  current law the assets of the
Company do not appear  likely to be assets of Plans  receiving  shares of Common
Stock or New Common Stock as a result of the UPREIT  Transactions.  However,  if
the assets of the Company were deemed to be assets of Plans under ERISA, the

                                    -119-

<PAGE>

directors of the Company would likely be  fiduciaries  with respect to the Plans
that invest in the Company and the prudence and other  fiduciary  standards  set
forth in ERISA would apply to the directors and to all  investments  made by the
Company.  Plan  fiduciaries  who make the decision to invest in the Common Stock
could,  under certain  circumstances,  be liable as  co-fiduciaries  for actions
taken by the Company or the directors that do not conform to the ERISA standards
for investments under Part 4 of Title I of ERISA.

PROHIBITED TRANSACTIONS

     Section 406 of ERISA provides that Plan  fiduciaries  are  prohibited  from
causing  a Plan to engage  in  certain  types of  transactions.  Section  406(a)
prohibits  a  fiduciary  from  knowingly  causing a Plan to engage  directly  or
indirectly  in,  among other  things:  (a) a sale or  exchange,  or leasing,  of
property with a party in interest;  (b) a loan or other extension of credit with
a party in  interest;  (c) a  transaction  involving  the  furnishing  of goods,
services or facilities with a party in interest;  or (d) a transaction involving
the  transfer of Plan assets to, or use of Plan assets by or for the benefit of,
a party in interest.  Additionally,  Section 406 prohibits a Plan fiduciary from
dealing with Plan assets in his own interest or for his own account, from acting
in any capacity in any  transaction  involving the Plan on behalf of a party (or
representing  a party) whose  interests are adverse to the interest of the Plan,
and from receiving any  consideration for his own account from any party dealing
with the Plan in connection  with a transaction  involving Plan assets.  Similar
provisions in Section 4975 of the Code apply to qualified  Plans, and to certain
other plans and individual retirement arrangements not subject to ERISA.

     If the assets of the Company were deemed to be assets of a Plan, a director
could be  characterized  as a fiduciary  of the Plan under ERISA or the Code.  A
director's  characterization  as a  fiduciary  would cause him to be deemed as a
"party in interest" under ERISA and a "disqualified  person" under the Code with
respect to a Plan (or other plan or individual retirement arrangement) receiving
Common Stock,  which could cause various  transactions  between the director and
the  Company to  constitute  prohibited  transactions  under ERISA and the Code.
Moreover,  if the assets of the  Company  were deemed to be assets of the Plans,
transactions between the Company and parties in interest or disqualified persons
with respect to any Plan (or other plan or  individual  retirement  arrangement)
that has invested in the Company could be prohibited  transactions  with respect
to the Plan, unless a statutory or administrative exemption is available.

     If a prohibited  transaction has occurred,  certain of the parties involved
in the transaction could be required to (a) undo the transaction, (b) restore to
the Plan any profit realized on the  transaction,  (c) make good to the Plan any
loss  suffered  by it as a result of the  transaction  and (d) pay an excise tax
equal to fifteen  percent of the "amount  involved" in the  transaction for each
year in which the transaction  remains  uncorrected.  If such transaction is not
corrected within the "taxable  period," as defined in Section  4975(f)(2) of the
Code, the parties involved in the transaction could be required to pay an excise
tax equal to 100% of the "amount involved."

     If the  investment  constituted  a  prohibited  transaction  under  Section
408(e)(2)  of the  Code  by  reason  of the  Company  engaging  in a  prohibited
transaction  with  the  individual  who  established  an  individual  retirement
arrangement  ("IRA")  or his  beneficiary,  the IRA  would  lose its  tax-exempt
status. The other penalties for prohibited transactions would not apply.

REPORTING AND DISCLOSURE

     As part of the reporting and  disclosure  requirements  applicable to Plans
under  ERISA and the  Code,  fiduciaries  of a Plan are  required  to  determine
annually  the fair  market  value of the  assets of such Plan as of the close of
such Plan's fiscal year and to file annual  reports  valuing such assets.  Since
the  Common  Stock and New  Common  Stock are or will be listed on the AMEX (and
that the assets of the Company will not be deemed to be assets of the Plans) and
are  expected  to be trading on the AMEX  following  consummation  of the UPREIT
Transactions,  the  requirements  for valuation  should be complied with by such
listing and trading.

                 (DOLLARS IN THOUSANDS, EXCEPT PER SHARE DATA)


1.   ORGANIZATION AND BASIS OF PRESENTATION:

     The pro forma consolidated  financial statements of Mission West Properties
     (the  "Company")  have  been  prepared  based on the  historical  financial
     statements of the Company,  the Berg Properties and the Acquired Properties
     considering the effects of the Berg Acquisition, Reincorporation Merger and
     the Private Placement.

     The  Company  and all  parties  to the  Acquisition  Agreement  agreed  to
     consummate the Berg  Acquisition  wherein the Company  acquired the general
     partner  interests in the Operating  Partnerships,  effective for financial
     and income accounting and reporting purposes as of July 1, 1998.

     Accordingly,  the historical  consolidated  balance sheet of the Company at
     September 30, 1998 reflects the consummation of the Berg  Acquisition.  The
     pro forma  balance  sheet of the  Company at  September  30,  1998 has been
     prepared as if the  Reincorporation  Merger and Private  Placement has been
     consummated at September 30, 1998.  The pro forma  statements of operations
     for the nine  months  ended  September  30,  1998  and for the  year  ended
     December  31,  1997  have  been  prepared  as  if  the  Berg   Acquisition,
     Reincorporation  Merger  and  Private  Placement  had been  consummated  on
     January 1, 1997. In  management's  opinion,  all  adjustments  necessary to
     reflect the  effects of the Berg  Acquisition,  Reincorporation  Merger and
     Private Placement have been made. The pro forma financial statements should
     be read in conjunction with the historical financial statements.

     The unaudited pro forma financial statements are not necessarily indicative
     of what the actual financial position would have been at September 30, 1998
     had the Reincorporation  Merger and Private Placement occurred on September
     30, 1998,  nor the actual  results of operations  for the nine months ended
     September  30,  1998 or for the year ended  December  31, 1997 had the Berg
     Acquisition,  Reincorporation  Merger and  Private  Placement  occurred  on
     January  1, 1997,  nor do they  purport  to  present  the future  financial
     position of the Company.

     In November 1997, the Board of Directors approved a change in the Company's
     fiscal  year  end from  November  30 to  December  31,  effective  with the
     calendar year beginning January 1, 1998.

     All share and per share  amounts have been adjusted to reflect the 1 for 30
     reverse stock split.

2.   ASSUMPTIONS:

     Certain assumptions  regarding the operations of the Company have been made
     in connection with the  preparation of the pro forma financial  statements.
     Those assumptions are as follows:

     a.   The pro forma financial statements assume that the Company has elected
          to be and  qualified as a real estate  investment  trust  ("REIT") for
          income tax reporting  purposes and has distributed  sufficient taxable
          income to meet the  requirements  of the  Internal  Revenue  Code and,
          therefore, incurred no income tax liabilities.

     b.   Rent has been  recognized on a  straight-line  method of accounting in
          accordance with generally accepted accounting principles.

     c.   General  and  administrative  expenses  historically  incurred  by the
          properties  and the  predecessor  entities  have been  reclassifed  to
          reflect  the  self-administered  structure  of  the  Company  and  the
          additional  expenses  of being a public  company.

                 (DOLLARS IN THOUSANDS, EXCEPT PER SHARE DATA)


     d.   Pro forma  net  income  per  share  information  is  calculated  using
          8,193,594  shares as the average number of shares  outstanding  during
          the pro forma periods.  For the pro forma periods, no other securities
          which,  if converted  or  exercised,  would have a dilutive  effect on
          earnings per share calculations.

3.   THE ACQUIRED AND BERG PROPERTIES:

     The Berg  Acquisition  was  accounted for as a purchase with the results of
     operations  of the  Operating  Partnerships  included  from  July 1,  1998.
     Accordingly,  the  historical  consolidated  statement of operations of the
     Company  includes the results of  operations  for the Berg  Properties  and
     Acquired Properties for the three months ended September 30, 1998. In order
     to reflect the  consummation of the Berg  Acquisition as of January 1, 1997
     for pro forma financial  statement  purposes,  the results of operations of
     the Berg  Properties  and the Acquired  Properties for the six months ended
     June 30, 1998 have been included.

     Straight-lined  rents and depreciation and amortization  have been adjusted
     to reflect the purchases as of the beginning of the period.

     A.   The Acquired Properties include  approximately 144,000 rentable square
          feet previously owned by a third party (the "Fremont Properties"),  as
          well as  approximately  416,000  rentable  square feet  consisting  of
          properties held by limited partnerships  previously controlled by John
          Kontrabecki as general partner (the "Kontrabecki Properties"). Certain
          entities related to the Berg Group owned non-controlling  interests in
          the Kontrabecki  Properties.  Operating  Partnership units aggregating
          6,694,027  have been exchanged in connection  with these  acquisitions
          and $39,138 of debt  collateralized  by the underlying  properties was
          assumed.  Subsequent to the closing of the $130,000 Prudential Secured
          Loan, $36,152 of such assumed debt has been repaid.

     B.   The acquired Berg Properties include approximately  3,780,000 rentable
          square feet currently owned by entities  previously  controlled by the
          Berg Group.  Operating  Partnership units aggregating  52,785,606 have
          been exchanged in connection with these  acquisitions  and $194,500 of
          debt   collateralized  by  the  underlying   properties  was  assumed.
          Subsequent  to the closing of the $130,000  Prudential  Secured  Loan,
          $107,440 of such assumed debt has been repaid.

4.   PRO FORMA ADJUSTMENTS:

     (1)  Concurrent with the UPREIT  Transactions,  the Company  anticipates it
          will sell  6,295,058  shares at $4.50 per share to certain  accredited
          investors  for net proceeds of $28,328 (the "New Private  Placement").
          In connection with this sale of common stock, a fee will be paid to an
          individual  in the form of  200,000  shares  of the  Company's  common
          stock.

     (2)  Upon the  closing  of the new  Private  Placement,  the  Company  will
          utilize those  proceeds along with available cash and a draw of $2,941
          on the lines of credit to repay the Demand Notes issued in  connection
          with the  closing of the  Company's  acquisition  of the sole  general
          partnership interests in the Operating Partnerships.

          The portion of the  outstanding  balance on the lines of credit in the
          amount of $2,941 and any  interest  accrued  thereon,  will effect the
          calculation  of  minority  interest.  On a pro forma  basis,  interest
          expense  on this  amount  is $160 and $213 for the nine  months  ended
          September  30, 1998,  and the twelve  months ended  December 31, 1997,
          respectively.

          Cash received by the Operating  Partnerships  from the Company will be
          maintained in order to pay future distributions.

     (3)  In October  1998,  the Company  utilized  funds of $4,625 drawn on the
          lines of credit to repay debt previously  collateralized by one of the
          properties owned by the Operating Partnerships. Such debt was included
          in Mortgage Notes Payable as of September 30, 1998.

     (4)  Adjustments  have been made to the pro forma  statements of operations
          for the nine  months  ended  September  30,  1998  and the year  ended
          December 31, 1997 in order to reflect the new capital structure of the
          Company. A reconciliation of interest expense on a pro forma basis for
          the nine months ended  September 30, 1998 and the year ended  December
          31, 1997 is as follows:

     (5)  Pro  forma   adjustments   have   been   made  in  order  to   reflect
          straight-lined  rents as if the Company  acquired the Berg  Properties
          and Acquired  Properties  on January 1, 1997 for the nine months ended
          September 30, 1998 and the year ended December 31, 1997.

     (6)  Upon the effective  date of the Company's  acquisition  of the general
          partnership  interests  in the  Operating  Partnerships,  real  estate
          assets were recorded at their estimated fair values.  Adjustments have
          been made to historical  depreciation  expense in order to reflect the
          higher cost basis to the Company.

     (7)  In connection  with the UPREIT  Transactions,  the Company will own an
          approximate  12.11% interest in the Operating  Partnerships and become
          their sole general partner.  Minority interest,  on a pro forma basis,
          is reconciled as follows:

     (8)  The Company  will be  self-managed  and will no longer pay  management
          fees.  Therefore,  the costs of managing the operations of the Company
          have  been  included  in the pro forma  statement  of  operations  and
          historical  management  fees have been  reclassified  to  reflect  the
          Company  as  a  self  managed  REIT.  The  Company  expects  to  incur
          additional  costs in excess of historical  general and  administrative
          expenses for such items as  shareholder  relations,  director fees and
          other such costs of operating as an active public company.

     (9)  The Company  intends to qualify and elect to be taxed as a real estate
          investment  trust under the Internal Revenue Code of 1986, as amended,
          commencing with the taxable year ending December 31, 1998.  Therefore,
          the  provision  for income tax expense has been  eliminated in the pro
          forma statement of operations.

                        REPORT OF INDEPENDENT ACCOUNTANTS




To the Berg Group:

We have audited the combined balance sheets and the financial statement schedule
of the Berg  Properties as described in Note 1 as of December 31, 1997 and 1996,
and the related combined statements of operations, net equity and cash flows for
each of the three years in the period ended December 31, 1997.  These  financial
statements and the financial  statement  schedule are the  responsibility of the
management of the Berg Properties.  Our  responsibility is to express an opinion
on these financial statements based on our audits.

We  conducted  our  audits  in  accordance  with  generally   accepted  auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the  accounting  principles  used and  significant  estimates  made by
management,  as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion,  the combined  financial  statements  referred to above  present
fairly, in all material  respects,  the combined  financial position of the Berg
Properties as of December 31, 1997 and 1996,  and the combined  results of their
operations  and their cash flows for each of the three years in the period ended
December 31, 1997, in conformity with generally accepted accounting  principles.
In addition, in our opinion, the financial statement schedule referred to above,
when considered in relation to the basic financial  statements taken as a whole,
presents  fairly,  in all  material  respects,  the  information  required to be
included therein.

                    NOTES TO COMBINED FINANCIAL STATEMENTS
                   (DOLLARS IN THOUSANDS, EXCEPT SHARE DATA)

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

1.        ORGANIZATION AND BUSINESS:

          ORGANIZATION:

          The Berg Properties do not constitute a legal entity, but rather are a
          combination of various  research and  development  properties  held by
          entities  controlled  by the Carl E. Berg,  Clyde J. Berg,  members of
          their  immediate  families  and certain  entities  which they  control
          (collective,  the  "Berg  Group",  as  defined).  The Berg  Group  has
          historically been engaged in developing, owning, operating and selling
          income-producing  real estate primarily in the region  surrounding San
          Jose,  California.  In  addition to its real  estate  operations,  the
          controlled  Berg Group has been involved with other business  pursuits
          including technology venture capital funding, strategic investment and
          business  development.  The accompanying  financial statements reflect
          only  the  assets,  liabilities  and  results  of  operations  of Berg
          Properties,  which will be  controlled  by the Company  following  the
          consummation of the UPREIT Transactions.

          BUSINESS:

          On  September 2, 1997,  the Berg Group  purchased  6,000,000  (200,000
          giving  effect to a 1 for 30 reverse  stock  split in  November  1997)
          newly issued  shares of common stock of Mission West  Properties  (the
          "Company"), an American Stock Exchange listed real estate company that
          completed the sale of all of its real estate holdings  earlier in 1997
          (the  "Initial   Investment").   Upon   consummation  of  the  Initial
          Investment,  the Berg  Group  beneficially  owned  79.6% of the voting
          securities  of the  Company.  Subsequent  to the Initial  Investment a
          series of  transactions  were approved by the  Company's  shareholders
          that included a 1 for 30 reverse stock split,  a private  placement of
          1,250,000  shares of the Company's common stock at $4.50 per share and
          the adoption of the Company's  stock option plan,  and a change in the
          Company's  year end from  November 30 to December 31. The Company also
          hired a new management team and issued options under the stock plan to
          key employees  for the purchase of 755,000  shares at $4.50 per share.
          In March 1997,  one officer  exercised an option to 200,000  shares of
          common  stock at $4.50 per  pursuant to a  restricted  stock  purchase
          agreement.

          Pursuant to the UPREIT  Transactions  (as defined in the  Registration
          Statement on Form S-4),  the Berg Group will transfer its  development
          and property management business to an operating  partnership of which
          the Company will be the sole general  partner and own a percentage  of
          the  operating  partnership,  will purchase  approximately  $69,300 of
          income producing real estate, certain outstanding  indebtedness of the
          Berg Properties will be repaid, a third-party investment approximating
          $28,300 (net of offering  costs) will be received by the Company,  and
          the Company will elect to be taxed as a real estate  investment  trust
          for  its  fiscal  year-end  beginning  January  1,  1998.   Therefore,
          effective with the  transactions  related to the UPREIT  Transactions,
          the  management of the historic Berg  Properties  and the  acquisition
          properties  will be  performed  by the  Company  and its  consolidated
          operating  partnership,  and  the  Company  will  operate  under a new
          capital structure.

2.        BASIS  OF  PRESENTATION  AND  SUMMARY  OF  SIGNIFICANT  ACCOUNTING
          POLICIES:

          PRINCIPLES OF COMBINATION:

          The financial  statements  have been presented on a combined basis, at
          historical cost, because the Berg Properties has been under the common
          control of the Berg Group. All significant intergroup transactions and
          balances have been eliminated in combination.

          INTERIM UNAUDITED FINANCIAL INFORMATION:

          The  accompanying  interim  unaudited  financial  statements have been
          prepared  pursuant to the rules and  regulations of the Securities and
          Exchange  Commission.  Certain  information  and footnote  disclosures
          normally included in the financial  statements  prepared in accordance
          with generally accepted accounting

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

   
          principles may have been  condensed or omitted  pursuant to such rules
          and regulations, although management believes that the disclosures are
          adequate to make the  information  presented  not  misleading.  In the
          opinion of management,  all adjustments and  eliminations,  consisting
          only of normal, recurring adjustments, necessary to present fairly the
          financial  position  of the Berg  Properties  as of June 30,  1998 and
          1997, and the results of their operations and cash flows for the three
          months ended June 30, 1998 and 1997,  have been included.  The results
          of operations for such interim periods are not necessarily  indicative
          of the results of the full year.
    

          MANAGEMENT ESTIMATES:

          The  preparation of financial  statements in conformity with generally
          accepted  accounting  principles requires management to make estimates
          and  assumptions  that may affect the  reported  amounts of assets and
          liabilities and disclosure of contingent assets and liabilities at the
          dates of the financial statements and the reported amounts of revenues
          and expenses during the reporting periods. Actual results could differ
          from those estimates.

          REVENUE RECOGNITION:

          Rental income is recognized  on a  straight-line  method of accounting
          under which  contractual rent payment  increases are recognized evenly
          over the lease term.  Certain  lease  agreements  contain  terms which
          provide for additional  rents based on reimbursement of certain costs.
          These additional rents are reflected on the accrual basis.

          PROPERTY:

          Property  and  equipment is stated at the lower of cost or fair value.
          Cost includes  expenditures  for  improvements or replacements and the
          net  amount  of  interest  cost  associated  with  capital  additions.
          Capitalized  interest  was $257 in 1997 and $459 in 1996.  Maintenance
          and repairs are charged to expense as incurred.  Gains and losses from
          sales are included in income in accordance  with Financial  Accounting
          Standards No. 66, ACCOUNTING FOR SALES OF REAL ESTATE.

          Losses in  carrying  values  of  investment  assets  are  provided  by
          management when the losses become apparent and the investment asset is
          considered  impaired.  Management  evaluates is investment assets on a
          periodic  basis,  to assess  whether any  impairment  indications  are
          present.  If an investment asset is considered to be impaired,  a loss
          is provided to reduce the carrying  value of the  investment  asset to
          its  estimated  fair  value.  No such  losses  have been  required  or
          provided in the accompanying financial statements.

          DEPRECIATION:

          Depreciation is computed using the straight-line method over estimated
          useful lives of 40 years for  buildings,  over the life of lease terms
          which  average  10 years  for  tenant  improvements,  and 10 years for
          furniture and equipment.

          STATEMENTS OF CASH FLOWS:

          Cash and cash equivalents include all cash and liquid investments with
          an original  maturity  date from date of  purchase of three  months or
          less.

          EXTERNAL LEASE ACQUISITION COSTS:

          External lease  acquisition  costs are  capitalized and amortized over
          the lives of the related leases.

          LOAN FEES:

          Loan fees are stated at cost and are being amortized under a method of
          accounting which  approximates the effective  interest method over the
          terms of the related notes. Upon refinancing,  property disposition or
          loan termination, such fees are directly written-off.

               NOTES TO COMBINED FINANCIAL STATEMENTS, CONTINUED
                   (DOLLARS IN THOUSANDS, EXCEPT SHARE DATA)

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

          INCOME TAXES:

          No federal or state income taxes are payable by the entities which own
          the  Berg   Properties   and  none  have  been  provided  for  in  the
          accompanying  financial  statements,  as such  properties are owned by
          partnerships  whose partners are required to include their  respective
          share of profits and losses in their individual tax returns.

          CONCENTRATION OF CREDIT RISK:

          Management of the Berg Properties  performs ongoing credit evaluations
          of their tenants. The Berg Properties are not geographically  diverse,
          and  their  tenants  operate  primarily  in the  technology  industry.
          Additionally,  because the Berg  Properties  are leased to 71 tenants,
          default by any major tenant could significantly  impact the results of
          the  combined  total.  The largest of such  tenants,  calculated  as a
          percentage of aggregate base rent, are Apple Computers,  Inc.,  16.3%;
          Amdahl  Corporation,  8.7%; Cisco Systems,  Inc., 7.2%; and nine other
          tenants, approximating 24.6%. However, management believes the risk of
          such a default is  reduced  because  of the  critical  nature of these
          properties for ongoing tenant operations.

          COMMITMENTS AND CONTINGENCIES:

          Members  of the  Berg  Group  and the  entities  which  hold  the Berg
          Properties are party to litigation arising out of the normal course of
          business.  While the  ultimate  results of any such  lawsuits or other
          proceedings  cannot be predicted with  certainty,  management does not
          expect that these matters will have a material  adverse  effect on the
          combined  financial  position  or  results of  operations  of the Berg
          Properties.

          Insurance policies currently  maintained by the Berg Properties do not
          cover damage caused by seismic activity, although they do cover losses
          from fires after an earthquake.

3.        EXTERNAL LEASE ACQUISITION COSTS:

          Included  in  other  assets  are  external  lease  acquisition  costs.
          Accumulated  amortization related to these costs aggregated $1,353 and
          $661 as of December 31, 1997 and 1996, respectively.

4.        LOAN FEES:

          Included  in other  assets  are loan  fees.  Accumulated  amortization
          related to these fees aggregated $198 and $186 as of December 31, 1997
          and 1996, respectively.

5.        NOTES PAYABLE:

          Historically, the Berg Properties have had access to credit facilities
          entered  into by  members  of the  Berg  Group.  Balances  under  such
          facilities  have been  allocated  to  entities  within  the Berg Group
          generally  based  on  approximate   use  of  the  credit   facilities.
          Borrowings  under these  credit  facilities  have been used to finance
          various  ventures  including  commercial  real estate  development and
          acquisition,   including   assets  that  are   included  in  the  Berg
          Properties,  technology  venture capital  investments and other assets
          unrelated to real estate not included in these financial statements.

          Included in the accompanying  financial statements is an allocation of
          certain lines of credit with an aggregate borrowing limit of $130,000.
          These lines of credit  facilities are  collateralized  by certain Berg
          Properties   and  other   assets  of  the  Berg  Group.   Among  other
          requirements,  the credit  facilities  have  covenants  requiring  the
          owners to  maintain  certain  levels of  personal  net worth and carry
          interest  rates  based on the prime rate in effect on the first day of
          each calendar month, less the Purchased Funds Rate quoted on the first
          day of each calendar month less 1.65%, which was 7.24% at December 31,
          1997.  Aggregate  borrowings  outstanding  under  the  lines of credit
          facilities at December 31, 1997 totaled $99,192 with $37,953 allocated
          to the Berg

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

          Properties and included in these financial statements. Included in the
          aggregate   borrowing   under  the  line  of  credit   facilities   is
          approximately $12,000 related to an embezzlement by a former employee.
          Amounts  allocated to the Berg  Properties  do not include any amounts
          related to the theft as such  amounts  have been  allocated to certain
          Berg Group Members.

          Pursuant to the UPREIT Transactions,  it is anticipated that the notes
          payable of the Berg  Properties  will be  restructured  and/or retired
          through a combination of new debt and equity.

          Principal  payments on outstanding  borrowings as of December 31, 1997
          are due as follows:

6.       FAIR VALUES OF FINANCIAL INSTRUMENTS:

         SFAS No. 107,  DISCLOSURES  ABOUT FAIR VALUE OF FINANCIAL  INSTRUMENTS,
         requires   disclosure  of  fair  value   information   about  financial
         instruments,  whether or not  recognized  in the statement of financial
         condition, for which it is practicable to estimate that value. In cases
         where quoted  market  prices are not  available,  fair values are based
         upon estimates using present value or other valuation techniques. Those
         techniques  are   significantly   affected  by  the  assumptions  used,
         including  the discount rate and the  estimated  future cash flows.  In
         that regard,  the derived fair value estimates  cannot be substantiated
         by comparison to independent  markets and, in many cases,  could not be
         realized  in  immediate  settlement  of the  instrument.  SFAS No.  107
         excludes   certain   financial   instruments   and  all   non-financial
         instruments from its disclosure requirements.

         The following summarizes the financial  instruments and the estimate of
         the fair value of each class of financial  instruments  for which it is
         practicable to estimate that value:

                  CASH AND CASH EQUIVALENTS:

                  The carrying amount of cash and cash equivalents is considered
                  to be a reasonable estimate of fair value.

                  MORTGAGE NOTES PAYABLE:

                  In accordance with the  requirements of Statement of Financial
                  Accounting Standards No. 107, "Disclosures about Fair Value of
                  Financial Instruments," management has estimated that mortgage
                  notes payable with an aggregate carrying value of $38,554 have
                  on estimated aggregate fair value of $38,211 at December 31,
                  1997.

7.       RELATED PARTY TRANSACTIONS:

         The Berg Properties are held by partnerships that have received certain
         management services and financing from members of the Berg Group to the
         benefit of the  partnerships  and the  properties.  Such  services have
         included general operating  expenses,  office space, and administrative
         and technical  assistance.  The  partnerships  have reimbursed the Berg
         Group  members for the cost of  providing  such  services  and property
         management services on a fee basis.  Expenses related to the properties
         for  general and  property-specific  services  paid to related  parties
         aggregated  $1,050,  $827,  and $654 for the years ended  December  31,
         1997, 1996, and 1995, respectively.

         Included  in the  financing  described  in Note 5,  certain  affiliated
         entities  have  extended  funds  to  the  partnerships  which  own  the
         properties.  These  amounts  are  included  in notes  payable  (related
         parties)  on the  combined  balance  sheet.  Such  amounts are due upon
         demand and accrue interest at a rate equal to that charged on the lines
         of credit facilities and interest incurred on such advances is included
         in interest  expense  (related  parties) in the combined  statements of
         operations.

8.       OPERATING LEASES:

         The Berg  Properties  are leased to tenants under net operating  leases
         with initial term expiration  dates extending to the year 2008.  Future
         minimum rentals under noncancelable operating leases,  excluding tenant
         reimbursements  of expenses as of December 31, 1997, are  approximately
         as follows:

         Minimum rental revenues,  as presented for the years ended December 31,
         1997,  1996 and 1995,  contain  straight-line  adjustments  for  rental
         revenue  increases in accordance  with  generally  accepted  accounting
         principles.  The aggregate rental revenue increases  resulting from the
         straight-line  adjustments  for the years ended December 31, 1997, 1996
         and 1995 were $1,301, $586, and $77, respectively.

9.       EXTRAORDINARY ITEMS:

         In 1996 and 1995,  net  gains of $610 and  $3,206,  respectively,  were
         realized  as  a  result  of  early   extinguishment   of  certain  debt
         obligations.

                        REPORT OF INDEPENDENT ACCOUNTANTS


To the Berg Group:

We have audited the  accompanying  Statement of Revenue and Certain  Expenses of
the Fremont  Properties  as described in Note 2 for the year ended  December 31,
1997. The Statement of Revenue and Certain Expenses is the responsibility of the
management  of the  Fremont  Properties.  Our  responsibility  is to  express an
opinion on the Statement of Revenue and Certain Expenses based on our audit.

We conducted our audit in accordance with generally accepted auditing standards.
Those standards  require that we plan and perform the audit to obtain reasonable
assurance   about  whether  the  financial   statements  are  free  of  material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the  accounting  principles  used and  significant  estimates  made by
management,  as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.

The accompanying  Statement of Revenue and Certain Expenses was prepared for the
purpose  of  complying  with the rules and  regulations  of the  Securities  and
Exchange Commission,  for inclusion in the registration statement on Form S-4 of
Mission  West  Properties  as  described  in Note 1, and is not intended to be a
complete presentation of the Fremont Properties' revenue and expenses.

In our opinion,  the Statement of Revenue and Certain Expenses referred to above
present fairly,  in all material  respects,  the revenue and certain expenses of
the Fremont Properties described in Note 2 for the year ended December 31, 1997,
in conformity with generally accepted accounting principles.

               NOTES TO STATEMENT OF REVENUE AND CERTAIN EXPENSES

                                   ----------


1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

     BASIS OF PRESENTATION:

     The accompanying Statement of Revenue and Certain Expenses was prepared for
     the purpose of complying  with the rules and  regulations of the Securities
     and Exchange Commission for inclusion in the registration statement on Form
     S-4  of  Mission  West  Properties.   The  accompanying  statement  is  not
     representative  of the actual  operations  of the  Fremont  Properties,  as
     defined  in Note 2, for the  period  presented  nor  indicative  of  future
     operations.  Certain  expenses,  primarily  depreciation,  amortization and
     interest  expense,  which may not be comparable to the expenses expected to
     be incurred by Mission West Properties in future  operations of the Fremont
     Properties, have been excluded.

     REVENUE AND EXPENSE RECOGNITION:

     Revenue  is  recognized  on a  straight-line  basis  over the  terms of the
     related  leases.  Expenses are  recognized  in the period in which they are
     incurred.

     USE OF ESTIMATES:

     The  preparation  of the  Statement  of Revenue  and  Certain  Expenses  in
     conformity  with  generally   accepted   accounting   principles   requires
     management  to make  estimates  and  assumptions  that affect the  reported
     amounts of the combined revenue and expenses during the reporting  periods.
     Actual results could differ from these estimates.

2. DESCRIPTION OF PROPERTIES:

     The  accompanying  Statement of Revenue and Certain  Expenses relate to the
     combined  operations of three  properties at 4050  Starboard  Drive,  45700
     Northport Loop East and 45738 Northport Loop West. The commercial buildings
     have  approximately  144,000 rental square feet and are located in Fremont,
     California.  The Fremont Properties have been presented on a combined basis
     because the Fremont  Properties were under common  ownership and management
     of the developer.

     The  Properties  were  developed  with  physical  completion  and  lease-up
     concluded  in  the  first  quarter  of  1997.  Therefore  no  prior  period
     information is available.

3. RENTALS:

     The Properties  have entered into tenant leases that provide for tenants to
     share in the operating  expenses and real estate taxes on a pro rata basis,
     as defined.

To the Berg Group:

We have  audited the  accompanying  combined  Statements  of Revenue and Certain
Expenses of the  Kontrabecki  Properties  as  described  in Note 2 for the years
ended  December 31, 1997,  1996 and 1995.  The Statements of Revenue and Certain
Expenses are the responsibility of the management of the Kontrabecki Properties.
Our  responsibility  is to express an opinion on these Statements of Revenue and
Certain Expenses based on our audits.

We  conducted  our  audits  in  accordance  with  generally   accepted  auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the  accounting  principles  used and  significant  estimates  made by
management,  as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

on Form  S-4 of  Mission  West  Properties  as  described  in Note 1, and is not
intended to be a complete  presentation of the Kontrabecki  Properties'  revenue

In our opinion, the combined Statements of Revenue and Certain Expenses referred
to above presents  fairly,  in all material  respects,  the combined revenue and
certain expenses of the Kontrabecki Properties described in Note 2 for the years
ended December 31, 1997,  1996 and 1995, in conformity  with generally  accepted
accounting principles.

                             KONTRABECKI PROPERTIES
          NOTES TO COMBINED STATEMENTS OF REVENUE AND CERTAIN EXPENSES

                                   ----------

1.       SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

                  BASIS OF PRESENTATION:

                  The  accompanying  combined  Statements of Revenue and Certain
                  Expenses were  prepared for the purpose of complying  with the
                  rules  and   regulations   of  the   Securities  and  Exchange
                  Commission for inclusion in the registration statement on Form
                  S-4 of Mission  West  Properties.  The  accompanying  combined
                  statements are not  representative of the actual operations of
                  the  Kontrabecki  Properties,  as  defined  in Note 2, for the
                  periods presented nor indicative of future operations. Certain
                  expenses,  primarily  depreciation,  amortization and interest
                  expense,  which may not be comparable to the expenses expected
                  to be incurred by Mission West Properties in future operations
                  of the Properties, have been excluded.

                  REVENUE AND EXPENSE RECOGNITION:

                  Revenue is recognized on a straight-line  basis over the terms
                  of the related  leases.  Expenses are recognized in the period
                  in which they are incurred.

                  USE OF ESTIMATES:

                  The  preparation  of the  combined  Statements  of Revenue and
                  Certain   Expenses  in  conformity  with  generally   accepted
                  accounting  principles  requires  management to make estimates
                  and  assumptions  that  affect  the  reported  amounts  of the
                  combined  revenue and expenses  during the reporting  periods.
                  Actual results could differ from these estimates.

2.       DESCRIPTION OF THE PROPERTIES:

          The accompanying  combined  Statements of Revenue and Certain Expenses
          relate  to the  combined  operations  of the  Kontrabecki  Properties,
          office  buildings with  approximately  416,000  rentable  square feet,
          located in Santa Clara,  California.  The Kontrabecki  Properties have
          been presented on a combined basis because the Kontrabecki  Properties
          were under common ownership and management.

3.       RENTALS:

          The Kontrabecki  Properties' management has entered into tenant leases
          that provide for tenants to share in the  operating  expenses and real
          estate  taxes on a pro forma  basis,  as  defined.  During  the fourth
          quarter of 1996 and throughout 1997,  occupancy  increase  obtained at
          the Kontrabecki  Properties allowed for a significant  portion of such
          expenses  to  be  charged  to  the  tenants   pursuant  to  the  lease
          agreements.

                       INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 20.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

     As permitted by Section 204(a) of the California  General  Corporation Law,
the  Registrant's  articles of  incorporation  eliminate a  director's  personal
liability for monetary  damages to the Registrant and its  shareholders  arising
from a breach or alleged breach of the  director's  fiduciary  duty,  except for
liability  arising  under  Section  310  and  316  of  the  California   General
Corporation Law or liability for (i) acts or omissions that involve  intentional
misconduct or knowing and culpable violation of law, (ii) acts or omissions that
a director  believes to be contrary to the best  interests of the  Registrant or
its  shareholders  or that  involve the absence of good faith on the part of the
director,  (iii) any  transaction  from  which a director  derived  an  improper
personal benefit,  (iv) acts or omissions that show a reckless disregard for the
director's duty to the Registrant or its  shareholders in circumstances in which
the director  was aware,  or should have been aware,  in the ordinary  course of
performing a director's duties, of a risk of serious injury to the Registrant or
its shareholders and (v) acts or omissions that constitute an unexcused  pattern
of  inattention  that amounts to an  abdication  of the  director's  duty to the
Registrant or its shareholders. This provision does not eliminate the directors'
duty of care, and in  appropriate  circumstances  equitable  remedies such as an
injunction or other forms of  non-monetary  relief would remain  available under
California Law.

     Sections 204(a) and 317 of the California General Corporation Law authorize
a corporation to indemnify its directors,  officers,  employees and other agents
in terms sufficiently broad to permit indemnification  (including  reimbursement
for expenses)  under certain  circumstances  for  liabilities  arising under the
Securities  Act of 1933,  as  amended.  The  Registrant's  Restated  Articles of
Incorporation  and  Bylaws  contain  provisions   covering   indemnification  of
corporate  directors,  officers and other agents against certain liabilities and
expenses  incurred as a result of  proceedings  involving  such persons in their
capacities as directors,  officers,  employees or agents,  including proceedings
under the Securities Act or the Securities Exchange Act of 1934, as amended. The
Company has not entered into  indemnification  agreements with its directors and
executive officers.

ITEM 22.  UNDERTAKINGS.

(a)  The undersigned Registrant hereby undertakes:

     (1) To file,  during any period in which  offers or sales are being made, a
post-effective amendment to this registration statement:

          (i)  To include any prospectus required by section 10(a)(3) of the
Securities Act of 1933;

          (ii) To reflect in the  prospectus  any facts or events  arising after
the  effective  date  of  the   registration   statement  (or  the  most  recent
post-effective  amendment  thereof)  which,  individually  or in the  aggregate,
represent a fundamental  change in the information set forth in the registration
statement.  Notwithstanding the foregoing, any increase or decrease in volume of
securities  offered (if the total dollar value of  securities  offered would not
exceed that which was  registered) and any deviation from the low or high end of
the estimated  maximum offering range may be reflected in the form of prospectus
filed with the  Commission  pursuant  to Rule 424(b) if, in the  aggregate,  the
changes in volume and price  represent  no more than a 20 percent  change in the
maximum  aggregate  offering price set forth in the "Calculation of Registration
Fee" table in the effective registration statement;

          (iii) To include any material  information with respect to the plan of
distribution  not  previously  disclosed  in the  registration  statement or any
material change to such information in the registration statement;

     (2) To remove from registration by means of a post-effective  amendment any
of the securities being registered which remain unsold at the termination of the
offering.

(b)  The  undersigned   Registrant  hereby  undertakes  that,  for  purposes  of
determining  any liability  under the Securities Act of 1933, each filing of the
Registrant's  annual  report  pursuant to Section  13(a) or Section 15(d) of the
Exchange Act (and, where  applicable,  each filing of an employee benefit plan's
annual  report   pursuant  to  Section  15(d)  of  the  Exchange  Act)  that  is
incorporated by reference in this Registration Statement shall be deemed to be a
new registration  statement relating to the securities offered therein,  and the
offering of such  securities at that time shall be deemed to be the initial bona
fide offering thereof.

(c) The  undersigned  Registrant  hereby  undertakes  to  deliver or cause to be
delivered with the prospectus,  to each person to whom the prospectus is sent or
given,  the latest annual report,  to security  holders that is  incorporated by
reference  in  the  prospectus  and  furnished   pursuant  to  and  meeting  the
requirements of Rule 14a-3 or Rule 14c-3 under the Securities  Exchange Act and,
where  interim  financial  information  required to be presented by Article 3 of
Regulation S-X is not set forth in the  prospectus,  to deliver,  or cause to be
delivered  to each person to whom the  prospectus  is sent or given,  the latest
quarterly  report  that  is  specifically   incorporated  by  reference  in  the
prospectus to provide such interim financial information.

(d) The undersigned  Registrant hereby undertakes as follows:  that prior to any
public  reoffering  of the  securities  registered  hereunder  through  use of a
prospectus  which is a part of this  registration  statement,  by any  person or
party who is deemed to be an underwriter  within the meaning of Rule 145(c), the
registrant   undertakes  that  such  reoffering   prospectus  will  contain  the
information  called  for by the  applicable  registration  form with  respect to
reofferings  by  persons  who may be deemed  underwriters,  in  addition  to the
information called for by the other items of the applicable form.


                                     II-4

<PAGE>

(e) The undersigned  Registrant  undertakes that every  prospectus:  (i) that is
filed pursuant to paragraph (d) immediately preceding,  or (ii) that purports to
meet the  requirements of Section  10(a)(3) of the Act and is used in connection
with an offering of  securities  subject to Rule 415, will be filed as a part of
an  amendment  to the  registration  statement  and will not be used  until such
amendment is  effective,  and that,  for purposes of  determining  any liability
under the Securities Act of 1933,  each such  post-effective  amendment shall be
deemed to be a new  registration  statement  relating to the securities  offered
therein,  and the offering of such securities at that time shall be deemed to be
the initial BONA FIDE offering thereof.

(f) Insofar as  indemnification  for liabilities under the Securities Act may be
permitted to  directors,  officers  and  controlling  persons of the  Registrant
pursuant  to the  provisions  described  in Item 15  above,  or  otherwise,  the
Registrant  has been advised that in the opinion of the  Securities and Exchange
Commission  and  indemnification  is against  public  policy as expressed in the
Securities  Act and is  therefore  unenforceable.  In the event  that a claim of
indemnification  against  such  liabilities  (other  than  the  payment  by  the
Registrant of expenses  incurred or paid by a director,  officer or  controlling
person  of the  Registrant  in a  successful  defense  of any  action,  suit  or
proceeding)  is  asserted by such  director,  officer or  controlling  person in
connection with the securities being registered,  the Registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of  appropriate  jurisdiction  the  question  of whether  such
indemnification  by it is against  public policy as expressed in the  Securities
Act and will be governed by the final adjudication of such issue.

(g) The  undersigned  Registrant  hereby  undertakes  to respond to requests for
information  that is incorporated  by reference into the prospectus  pursuant to
Item 4, 10(b),  11, or 13 of this form,  within one  business  day of receipt of
such  request,  and to send the  incorporated  documents  by first class mail or
other equally  prompt means.  This includes  information  contained in documents
filed subsequent to the effective date of the registration statement through the
date of responding to the request.

(h) The  undersigned  Registrant  hereby  undertakes  to  supply  by  means of a
post-effective  amendment  all  information  concerning a  transaction,  and the
company  being  acquired  involved  therein,  that  was not the  subject  of and
included in the registration statement when it became effective.

Re:   Registration Statement on Form S-4
      Registration No. 333-52835

Ladies and Gentlemen:

We render this opinion in connection with the registration of 93,398,705  shares
of common  stock,  $.001 par value per share (the "Common  Shares"),  of Mission
West  Properties,   Inc.,  a  Maryland  corporation  (the  "Company")  with  the
Securities and Exchange Commission on a Registration  Statement on Form S-4 (the
"Registration  Statement"),  relating to the  exchange of the Common  Shares for
shares of common stock of Mission  West  Properties,  a  California  corporation
("Mission   West-California"),   in  a   merger   entered   into  to   effect  a
reincorporation  of Mission  West-California.  We have examined such  documents,
records  and  matters  of law as we have  considered  relevant.  Based upon such
examination, it is our opinion that the Common Shares, when issued and delivered
in the manner and on the terms described in the Registration Statement,  will be
legally issued, fully paid, and nonassessable.

We  hereby  consent  to  the  filing  of  this  opinion  as an  exhibit  to  the
Registration  Statement  and to the  reference  to our firm in the  Registration
Statement.

Very truly yours,



Graham & James LLP




                 [Ballard Spahr Andrews & Ingersoll Letterhead]




           We have served as Maryland counsel to Mission West Properties,  Inc.,
a Maryland  corporation (the  "Company"),  in connection with certain matters of
Maryland law arising out of the merger of Mission West Properties,  a California
corporation  and the sole  stockholder  of the Company with and into the Company
(the "Reincorporation  Merger"), the conversion of shares of the Common Stock of
Mission  West  California  into shares of the  Company's  common stock $.001 par
value (the "New Common  Stock")  and the  registration  of the New Common  Stock
under the Securities Act of 1933, as amended (the "1933 Act"),  all as described
in the above-referenced  Registration  Statement under the 1933 Act. Capitalized
terms used but not defined  herein shall have the meanings  given to them in the
Registration Statement.

           In connection with our representation of the Company,  and as a basis
for the opinion  hereinafter  set forth, we have examined  originals,  or copies
certified  or  otherwise  identified  to  our  satisfaction,  of  the  following
documents (hereinafter collectively referred to as the "Documents"):

           1.  The  Registration  Statement,   including  the  related  form  of
prospectus  included  therein,  in the form in which it was  transmitted  by the
Company to the Securities and Exchange  Commission (the "Commission")  under the
1933 Act;

           2. The Articles of  Incorporation  of the company,  certified as of a
recent date by the State  Department  of  Assessments  and  Taxation of Maryland
("SDAT");

           3. Proposed Articles of Amendment and Restatement of the Company,  in
the form attached to the Registration  Statement as Exhibit 3.2.1 (the "Articles
of Amendment and Restatement");

           4. The Bylaws of the  Company,  certified as of the date hereof by an
officer of the Company;

           5.  Resolutions  adopted  by the Board of  Directors  of the  Company
relating to the  approval of the  Articles of  Amendment  and  Restatement,  the
authorization of the Reincorporation Merger and the issuance and registration of
the New Common Stock (the "Board of Resolutions") and resolutions adopted by the
stockholders  of the  Company  relating  to the  approval  of  the  Articles  of
Amendment and  Restatement and the approval of the  Reincorporation  Merger (the
"Stockholders  Resolutions",  and,  together  with the  Board  Resolutions,  the
"Resolutions"), certified as of the date hereof by an officer of the Company;

           6. The form of  certificate  representing  a share of the New  Common
Stock;

           7. A  certificate  of the SDAT,  as of a recent date,  as to the good
standing of the Company;

           8. A  certificate  executed by an officer of the  Company,  dated the
date hereof;

           9. The Merger Agreement and Plan of Merger,  certified as of the date
hereof by an officer of the Company; and

           10. Such other  documents and matters as we have deemed  necessary or
appropriate  to express  the opinion  set forth in this  letter,  subject to the
assumptions, limitations and qualifications stated herein.

           In expressing  the opinion set forth below,  we have assumed,  and so
far as is known to us there are no facts inconsistent with, the following:

           1. Each individual executing any of the Documents,  whether on behalf
of such individual or another person, is legally competent to do so.

           2. Each  individual  executing  any of the  Documents  on behalf of a
party (other than the Company) is duly authorized to do so.

           3. Each of the parties (other than the Company)  executing any of the
Documents has duly and validly  executed and delivered  each of the Documents to
which such party is a signatory,  and such party's obligations set forth therein
are legal,  valid and binding and are  enforceable in accordance with all stated
terms.

           4. Any Documents submitted to us as originals are authentic. The form
and content of any Documents  submitted to us as unexecuted drafts do not differ
in any  respect  relevant  to this  opinion  from the form and  content  of such
Documents as executed and delivered.  Any Documents submitted to us as certified
or photostatic copies conform to the original  documents.  All signatures on all
such Documents are genuine.  All public records reviewed or relied upon by us or
on our behalf are true and complete. All statements and information contained in
the  Documents  are  true  and  complete.  There  has  been no  oral or  written
modification  of or  amendment  to any of the  Documents,  and there has been no
waiver of any  provision of any of the  Documents,  by action or omission of the
parties or otherwise.

           5. Articles of Amendment and  Restatement  authorizing the Company to
issue up to  200,000,000  shares of common stock and otherwise in  substantially
the form attached to the  Registration  Statement as Exhibit 3.2.1 will be filed
with and accepted for record by the SDAT prior to the issuance of the New Common
Stock.

           The phrase "known to us" is limited to the actual knowledge,  without
independent  inquiry,  of the  lawyers  at our  firm who  have  performed  legal
services in connection with the issuance of this opinion.

           Based upon the foregoing, and subject to the assumptions, limitations
and qualifications stated herein, it is our opinion that:

           1. The Company is a corporation duly  incorporated and existing under
and by virtue of the laws of the State of Maryland and is in good  standing with
the SDAT.

           2. The New Common Stock is duly  authorized  and,  when and if issued
and delivered  against  payment  therefor in accordance with the Resolutions and
the Merger Agreement and Plan of Merger, will be validly issued,  fully paid and
nonassessable.

           The foregoing opinion is limited to the substantive laws of the State
of Maryland,  and we do not express any opinion herein concerning any other law.
We express no opinion as to the  applicability or effect of any federal or state
securities laws,  including the securities laws of the State of Maryland,  or as
to federal or state laws regarding fraudulent transfers.  To the extent that any
matter as to which our  opinion is  expressed  herein  would be  governed by any
jurisdiction other than the State of Maryland,  we do not express any opinion on
such matter.

           We assume no obligation to supplement  this opinion if any applicable
law changes  after the date hereof or if we become  aware of any fact that might
change the opinion expressed herein after the date hereof.

           This  opinion  is  being  furnished  to  you  for  submission  to the
Commission as an exhibit to the registration Statement and, accordingly, may not
be relied upon by,  quoted in any manner to, or delivered to any other person or
entity (other than Graham & James LLP, counsel to the Company) without,  in each
instance, our prior written consent.

           We hereby  consent to the filing of this opinion as an exhibit to the
Registration Statement and to the use of the name of our firm therein. In giving
this  consent,  we do not admit that we are within the category of persons whose
consent is required by Section 7 of the 1933 Act.

Very Truly Yours,


Ballard Spahr Andrews & Ingersoll

           Re:  Certain Federal Income Tax Matters

Ladies and Gentlemen:

           This  opinion  is  delivered  to you in our  capacity  as  counsel to
Mission West Properties, a California corporation,  ("Mission West") and Mission
West Properties,  Inc., a Maryland  corporation  ("Mission  West-Maryland"),  in
connection  with the amended  registration  statement on Form S-4 containing the
Proxy  Statement/Prospectus of Mission West addressed to holders of common stock
of  Mission  West  (the  "Proxy   Statement/Prospectus"),   which  Mission  West
originally  filed with the Securities  and Exchange  Commission on May 15, 1998.
The Proxy Statement/Prospectus  relates to the following proposals (i) the offer
and sale at $4.50 per share of 6,495,058  shares of common stock of Mission West
to accredited investors in a private placement (the "Private  Placement");  (ii)
the ratification of Mission West's  acquisition of  approximately  12.11% of the
total  partnership  interests in, and becoming the sole general partner of, each
of four limited  partnerships  for  $35,200,000  (collectively,  the  "Operating
Partnership");  (iii) the offer  and sale of up to  93,398,705  shares of common
stock of Mission  West  issuable  upon the future  exchange  of units of limited
partnership  interest  in the  Operating  Partnership;  and (iv) the  merger  of
Mission  West  with  and  into  Mission  West-Maryland  pursuant  to the  Merger
Agreement  and Plan of Merger (the  "Merger  Agreement")  (the  "Reincorporation
Merger").

           This opinion  relates to Mission  West-Maryland's  qualification  for
federal income tax purposes as a real estate investment trust ("REIT") under the
Internal  Revenue  Code of 1986,  as  amended  (the  "Code"),  the status of the
Operating Partnership as a partnership for federal income tax purposes,  and the
accuracy of the  discussion of federal  income tax  considerations  in the Proxy
Statement/Prospectus.  Certain  capitalized  terms not defined herein shall have
the meanings attributed to them in the Proxy Statement/Prospectus.

           In  rendering  the  following  opinions,  we have  examined the Proxy
Statement/Prospectus,  the  Articles  of  Incorporation  and  Bylaws of  Mission
West-Maryland,  the Merger  Agreement,  the Acquisition  Agreement among Mission
West  Properties,  Certain  Partnerships and the Berg Group (as defined therein)
dated as of May 14,  1998  (the  "Acquisition  Agreement"),  the  agreements  of
limited  partnership  of the  Operating  Partnership,  the pro  forma  financial
statements  of  Mission  West  prepared  as of  September  30,  1998 and for the
three-month  period  then ended  (the "Pro  Formas"),  and such  other  records,
certificates  and  documents  as we have deemed  necessary  or  appropriate  for
purposes  of  rendering  the open set forth  herein.  The  foregoing  documents,
including  the Pro Formas,  are referred to herein as the  "Documents".  We also
have relied upon the representations of Mission West, Mission West-Maryland, and
the Operating  Partnership regarding the manner in which such entities have been
and will be owned  and  operated  (the  "Management  Representations").  We have
neither  independently  investigated nor verified such  representations,  and we
assume that such  representations  are true,  correct and  complete and that all
representations  made "to the best of the knowledge and belief" of any person(s)
or party(ies) or with similar  qualification  are and will be true,  correct and
complete as if made  without  such  qualification  and that no action will occur
from the date hereof until the Reincorporation  Merger that is inconsistent with
such  representations.  We further  assume that the  Reincorporation  Merger and
related  transactions  contemplated  by the  Documents  will be  consummated  in
accordance with the Documents and as described in the Proxy Statement/Prospectus
(including  satisfaction  of all covenants and conditions to the  obligations of
the parties without  amendment or waiver thereof)  insofar as is relevant to the
opinions  contained herein and that, prior to the  Reincorporation  Merger,  all
entities have operated and will operate in accordance  with  applicable laws and
the terms and conditions of applicable  documents.  In addition,  we assume that
each of the limited partnerships  included in the Operating Partnership will be,
or will make a timely election to be, classified as a partnership as provided by
ss.301.7701-3 of the Procedure and Administration  Regulations promulgated under
the Code.

           In rendering the opinions set forth  herein,  we have assumed (i) the
genuineness  of  all  signatures  on  documents  we  have  examined,   (ii)  the
authenticity of all documents submitted to us as original,  (iii) the conformity
to the original  documents of all documents  submitted to s as copies,  (iv) the
conformity of final  documents to all documents  submitted to us as drafts,  (v)
the authority and capacity of the  individual  or  individuals  who executed any
such documents on behalf of any person,  (vi) the accuracy and  completeness  of
all  records  made  available  to us  and  (vii)  the  factual  accuracy  of all
representations,  warranties and other  statements made by all parties.  We also
have  assumed,   without  investigation,   that  all  documents,   certificates,
warranties  and  covenants on which we have relied in rendering the opinions set
forth  below and that were given or dated  earlier  than the date of this letter
continue  to remain  accurate,  insofar as relevant  to the  opinions  set forth
herein, from such earlier date through and including the date of this letter.

           The opinions set forth below are based upon the current provisions of
the  Code,  the  Income  Tax  Regulations   and  Procedure  and   Administration
Regulations  promulgated  thereunder,  all as of the date  hereof,  and existing
administrative and judicial  interpretations  thereof, all as of the date hereof
of which are subject to change.  Future  changes in applicable law may cause the
federal income tax treatment of Mission West and the Mission West-Maryland to be
materially and adversely different from that described below:

           Based upon and subject to the foregoing, we are of the opinion that:

1. Mission West-Maryland is organized, as of the date hereof, in conformity with
the  requirements  for  qualification  and taxation as a real estate  investment
trust ("REIT") under the Code, and Mission  West-Maryland's  proposed  method of
operation  (as  described  in the  Management  Representations),  including  for
periods   following  the   Reincorporation   Merger,   should   enable   Mission
West-Maryland  to  continue  to meet  the  requirements  for  qualification  and
taxation as a REIT for periods  following  the date  hereof,  including  periods
following the effective time of the Reincorporation Merger.

2. The Operating Partnership will be treated as a partnership for federal income
tax purposes and will not be subject to federal  income tax as a corporation  or
an association taxable as a corporation.

3. The discussion in the Proxy  Statement/Prospectus under the captions "FEDERAL
INCOME  TAX  CONSIDERATIONS,"  and  "FEDERAL  INCOME  TAX  CONSEQUENCES  OF  THE
REINCORPORATION MERGER", to the extent that such sections discuss matters of law
or legal conclusions, is accurate in all material respects.

           We express no opinion  herein  other than those  expressly  set forth
herein.  You should  recognize  that our opinion is not binding on the  Internal
Revenue  Service  (the "IRS"),  and that the IRS may  disagree  with the opinion
contained  herein.  Although we believe  that our opinion  will be  sustained if
challenged, there can be no assurance that this will be the case.

           We consent to being named as counsel to the Company and Mission  West
in  the   Proxy   Statement/Prospectus,   to  the   references   in  the   Proxy
Statement/Prospectus  to our firm and to the inclusion of a copy of this opinion
letter as an exhibit to the Proxy Statement/Prospectus.  In giving such consent,
however,  we do not thereby admit that we are an "expert"  within the meaning of
the Securities Act of 1933, as amended.  This opinion is being  furnished to you
solely  for  the  purpose  of  being   included  as  an  exhibit  to  the  Proxy
Statement/Prospectus.  This opinion may not be used or relied upon for any other
purpose without our prior written consent.



                                Very truly yours,

     the Maturity Date,  attributable to the Prepayment  Amount, at the Discount

     be used to discount within this period.

The entire unpaid  Principal  Balance,  plus accrued  interest and other amounts
payable under the Loan Documents, shall be due and payable on the Maturity Date.

3.     TREATMENT OF PAYMENTS.

      (a) Until directed otherwise in writing by Holder, all payments made under
      this Note shall be made by Electronic  Funds Transfer from Maker's account
      at an Automated  Clearing House member bank  satisfactory to Holder in its
      sole  discretion.  Maker shall  direct such bank in writing so to transfer
      payments on their due dates to Holder's designated  account.  Each payment
      shall be  initiated by Holder by  Electronic  Funds  Transfer  through the
      Automated  Clearing  House network for  settlement on each  respective due
      date.  Prior to each payment due date, Maker shall deposit and/or maintain
      sufficient  funds in Maker's  account to cover each debit entry to Maker's
      account.

      (b) Holder's approval and designation of a bank (or banks) under PARAGRAPH
      3(A)  above  shall  be  confirmed  in  writing.  Notwithstanding  Holder's
      approval  of a bank under  PARAGRAPH  3(A)  above,  Holder  shall have the
      right, upon thirty (30) days prior written notice to Maker, (i) to require
      Maker to use a  different  bank that is mutually  acceptable  to Maker and
      Holder, or (ii) to designate a different account for Holder.  All costs of
      establishing  and  maintaining  these  accounts  and all  costs  of  these
      Electronic Funds Transfers shall be paid by Maker.

      (c) For purposes of  calculating  interest  under this Note, a year of 360
      days  consisting  of twelve (12) thirty (30) days months shall be employed
      regardless of the actual time elapsed.

      (d) All payments due under this Note or the Loan  Documents  shall be paid
      by Maker in lawful money of the United  States of America on the date such
      payment is due. All such payments shall be made without  deduction for any
      present or future  taxes,  levies,  deductions,  charges  or  withholdings
      (including Federal,  state or local income taxes),  which amounts shall be
      paid by Maker.

      (e) Payments  from Maker to Holder under this Note shall be applied  first
      to any expense reimbursements under the Loan Documents,  then to any Daily
      Charges or Late  Charges,  as the case may be,  then to accrued and unpaid
      interest,  and the balance to the  Principal  Balance  and any  Prepayment
      Premium due thereon.

4. DAILY CHARGES; LATE CHARGES; SECONDARY INTEREST RATE.

     (a) If Maker fails timely to pay any sum due and payable under this Note on
     or before the date due, a late charge equal to Eight  Hundred Fifty Dollars
     ($850.00) per day (the "Daily  Charge") shall be due for each day that such
     sum is not paid (including, the day upon which the payment is made), but if
     such sum, together with the Daily Charges applicable  thereto,  is not paid
     by the fourteenth  (14th) day after the date such sum is due, a late charge
     equal to four cents  ($0.04) for each dollar  ($1.00) of each such sum (the
     "Late Charge")  shall be  immediately  due and payable in lieu of all Daily
     Charges.  Maker  acknowledges  and agrees  that its  failure to make timely
     payments will result in Holder  incurring  additional  expense in servicing
     the Loan, and that it is extremely  difficult and  impractical to ascertain
     the extent of such  damages  and that the Daily  Charge or the Late  Charge
     represent  a  fair  and  reasonable   estimate,   considering  all  of  the
     circumstances  existing on the date of the  execution of this Note,  of the
     costs that Holder will incur by reason of such late payment.  Acceptance of
     any  Daily  Charge or Late  Charge  shall  not  constitute  a waiver of the
     default with respect to the late payment, and shall not prevent Holder from
     exercising  any of the other rights or remedies  available  hereunder or at
     law or in equity.

     (b) Maker  further  acknowledges  and agrees  that during the time that any
     payment of principal, interest or other amount due under this Note shall be
     delinquent, Holder will incur additional costs and expenses attributable to
     its loss of use of the money  due and to the  adverse  impact  on  Holder's
     ability  to  meet  its  other   obligations   and  avail  itself  of  other
     opportunities.  Maker agrees that it is extremely difficult and impractical
     to ascertain the extent of such expenses,  and Maker therefore  agrees that
     upon the  occurrence  of an Event of  Default,  interest  at the  Secondary
     Interest Rate shall accrue on the Indebtedness, regardless of whether there
     has been an acceleration of the maturity of the Indebtedness.

5.  EVENT OF  DEFAULT.  The  occurrence  of an Event of  Default  under any Loan
Document  shall  constitute  an Event  of  Default  under  this  Note.  Upon the
occurrence of an Event of Default, including the failure of the Maker to observe
the provisions of Paragraph 4.2 of the Deed of Trust, Holder, at its option, may
cause the Principal  Balance,  together with all unpaid  accrued  interest,  any
Prepayment  Premium and any other sums  evidenced or secured by this Note or any
Loan Document,  to be immediately due and payable,  without further presentment,
demand, protest or notice of any kind, by so notifying Maker in writing.

6.  PREPAYMENT.

      (a) If for any reason the Principal Balance or any portion thereof is paid
      prior  to  the  Maturity  Date,  whether  voluntarily,  involuntarily,  by
      operation of law,  acceleration,  including  acceleration on account of an
      Event of Default and/or a violation of Paragraph 4.2 of the Deed of Trust,
      or  otherwise,  but  excluding  any  prepayment  made  as  result  of  the
      application  by Holder of  insurance  proceeds or  condemnation  awards as
      provided  by the terms of the Loan  Documents,  Maker shall pay to Holder,
      together  with  the  subject  Prepayment  Amount  and any  unpaid  accrued
      interest,  a prepayment  charge (the  "Prepayment  Premium")  equal to the
      greater of:

           (i) the  product of (A) one  percent  (1%) of the  Prepayment  Amount
           multiplied by (B) a fraction, the numerator of which is the number of
           full months  remaining  until the Maturity Date as of the  Prepayment
           Date  and the  denominator  of  which is the  number  of full  months
           comprising the Term of the Loan; or

           (ii) the Present Value of the  Prepayment  Amount less the sum of (A)
           the  Prepayment  Amount,  and (B) unpaid  accrued  interest,  if any,
           calculated as of the Prepayment Date.

      (b) Maker shall have the right voluntarily to prepay all or any portion of
      the Principal Balance, together with accrued interest thereon, but only if
      Maker gives Holder not less than thirty (30) days' prior written notice of
      its  intention  to  prepay,  and  delivers  to  Holder,  on or before  the
      Prepayment Date, the Prepayment Premium as calculated above, together with
      the  Prepayment  Amount and all accrued  interest and other sums due under
      the Loan Documents.  Notwithstanding  the foregoing,  Maker shall have the
      right to prepay the  Principal  Balance,  together  with accrued  interest
      thereon,  without payment of the Prepayment Premium,  during the period of
      time commencing fourteen (14) days immediately prior to the Maturity Date.

      (c) Maker  acknowledges  that (i) the  Prepayment  Premium  represents the
      reasonable estimate of Holder and Maker of a fair average compensation for
      the loss that may be  sustained by Holder due to the payment of any of the
      Principal Balance prior to the Maturity Date; (ii) the Prepayment  Premium
      shall be paid  without  prejudice  to the right of Holder to  collect  any
      other  amounts  provided  to be paid  hereunder  or under the  other  Loan
      Documents;  and (iii) Holder  shall not be obligated to actually  reinvest
      the Prepayment  Amount in any Treasury  Constant  Maturity Series or other
      specific investments as a condition to receiving the Prepayment Premium.

      (d) Maker acknowledges that it is comprised of four (4) different Persons,
      each of which owns  separately its Property,  and that the Loan is secured
      by the interest of all Persons  comprising  Maker in all of the  Property.
      Maker further acknowledges that in connection  therewith,  for purposes of
      allocating the Loan proceeds  appropriately  among the Persons  comprising
      Maker and their  respective  Property,  Maker and Holder agree to allocate
      the Loan proceeds in accordance with the Original Allocated Loan Amount as
      set  forth in  Exhibit  B to the Deed of  Trust  in  order to  ensure  the
      continuing adequacy of the security interest of Holder in each Property of
      Maker under the Loan  Documents.  Maker agrees that any  prepayment of the
      Loan,  unless otherwise  provided in the Loan Documents,  shall be applied
      pro rata  against  the  Original  Allocated  Loan  Amount (as set forth in
      Exhibit B to the Deed of Trust) of each Property.

      (e) Maker hereby  expressly  waives any right it may have under California
      Civil  Code  Section  2954.10 to prepay  this  Note,  in whole or in part,
      without  payment  of the  Prepayment  Premium,  upon  acceleration  of the
      Maturity  Date  of this  Note,  and  agrees  that  if for  any  reason,  a
      prepayment  of any or all of  this  Note  is  made,  whether  voluntarily,
      involuntarily  or upon or following any  acceleration of the Maturity Date
      of this  Note by  Holder,  then  Maker  shall pay the  Prepayment  Premium
      calculated pursuant to PARAGRAPH 6(a). By initialing this provision in the
      space provided below, Maker hereby declares that the Holder's agreement to
      make the Loan at the Interest Rate and for the Term set forth in this Note
      constitutes adequate consideration,  given individual weight by Maker, for
      this waiver and agreement.

                          INITIALS OF MAKER:  ____________________

7.  SECURITY.  This Note is  secured  by the Deed of Trust  and the  other  Loan
Documents, which contain provisions for the acceleration of the maturity of this
Note upon the occurrence of certain described events.

8.  HOLDER'S  RIGHTS;  NO WAIVER BY HOLDER.  The rights,  powers and remedies of
Holder  under this Note shall be in addition to all rights,  powers and remedies
given to Holder  under the Loan  Documents  and any other  agreement or document
securing or evidencing the  Indebtedness  or by virtue of any statute or rule of
law, including the California  Uniform Commercial Code. All such rights,  powers
and  remedies  shall  be  cumulative  and  may  be  exercised   successively  or
concurrently in Holder's sole discretion  without  impairing  Holder's  security
interest,  rights or available  remedies.  Any forbearance,  failure or delay by
Holder in  exercising  any right,  power or remedy  shall not  preclude  further
exercise thereof,  and every right,  power or remedy of Holder shall continue in
full force and effect until such right,  power or remedy is specifically  waived
in a writing executed by Holder. Maker waives any right to require the Holder to
proceed  against any Person or to exhaust all or any part of the  Property or to
pursue any remedy in Holder's power.

9. MAKER'S WAIVERS.

      (a) Maker and any endorsers of this Note,  and each of them,  hereby waive
      diligence, demand, presentment for payment, notice of non-payment, protest
      and notice of protest, and specifically consent to and waive notice of any
      renewals or extensions of this Note,  whether made to or in favor of Maker
      or any other  person or  persons.  Maker  and any  endorsers  of this Note
      expressly waive all right to the benefit of any statute of limitations and
      any moratorium,  reinstatement,  marshaling,  forbearance,  extension,  or
      appraisement now or hereafter provided by the Constitution and the laws of
      the  United  States and of any state  thereof,  as a defense to any demand
      against Maker or any such  endorsers,  to the fullest extent  permitted by
      law.

      (b) Maker  hereby  waives  any right to trial by jury with  respect to any
      action or proceeding brought by Holder or any other Person relating to (i)
      the Obligations, or (ii) the Loan Documents. Maker hereby agrees that this
      Note  constitutes a written consent to waiver of trial by jury pursuant to
      the provisions of California Code of Civil Procedure Section 631 and Maker
      does  hereby   constitute   and   appoint   Holder  its  true  and  lawful
      attorney-in-fact, which appointment is coupled with an interest, and which
      shall survive the dissolution or bankruptcy of any Maker, or any Transfer,
      and Maker does hereby authorize and empower Holder, in the name, place and
      stead of Maker,  to file this Note with the clerk or judge of any court of
      competent  jurisdiction as statutory written consent to waiver of trial by
      jury.

Documents,  may be  hypothecated,  transferred or assigned by Holder without the
prior consent of Maker.

writing  which by its  express  terms  refers  to this  Note  and  which is duly
executed by the party sought to be bound thereby.

imposed by any  applicable  state or  Federal  interest  rate laws.  If any such
payments in the nature of interest,  additional interest, and other charges made
hereunder  or under any  other  Loan  Documents  are held to be in excess of the
applicable  limits imposed by any applicable state or Federal laws, it is agreed
that  any such  amount  held to be in  excess  shall be  considered  payment  of
principal  and the  Principal  Balance  shall be reduced  by such  amount in the
inverse order of maturity so that the total liability for payments in the nature
of  interest,  additional  interest  and other  charges,  shall never exceed the
applicable  limits imposed by any applicable state or Federal interest rate laws
in compliance with the desires of Holder and Maker as set forth herein.

           which is governed by  Paragraph  18(c)(iv)  below)  without the prior
           written  consent of Holder,  if such  consent is  required  under the

           insolvency proceeding) any of Holder's enforcement actions.

      (c)  Except  as  provided  in  Paragraph  18(c)(v)  below,  the  agreement
      contained  in this  Paragraph  18 to limit the  personal  liability of the
      Exculpated  Parties  shall become null and void and of no further force or
      effect,  and the Exculpated  Parties shall have personal liability for all
      Indebtedness  and all  Obligations  evidenced  by the  Note  and the  Loan
      Documents, in the event:

           (i)    there is any breach or violation of Paragraph
           4.2 of the Deed of Trust;

           (ii) there is any fraud or material  misrepresentation  by any of the

           Holder,  if such  consent  is  required  under  the terms of the Loan
           Documents; or

           (v) the Property or any individual property constituting the Property
           is rendered  "environmentally  impaired",  as such term is defined in
           Section 726.5 of the California  Code of Civil  Procedure;  provided,

                                    ARTICLE 3
                              AFFIRMATIVE COVENANTS

Trustor hereby covenants and agrees as follows:

3.1. OBLIGATIONS OF TRUSTOR.  Trustor will timely perform, or cause to be timely
performed, all the Obligations.

3.2.  INSURANCE.

      A. Trustor,  at its sole cost and expense,  will keep and maintain for the
      mutual benefit of Trustor and Beneficiary:  (i) insurance  against loss or
      damage  to the  Property  by fire and other  risks  covered  by  insurance
      commonly known as "all risk", including losses sustained by reason of riot
      and civil commotion,  vandalism,  malicious mischief,  burglary, theft and
      mysterious  disappearance,  and coverage for  differences  in building and
      other code  requirements as a reconstruction of any damage or destruction,
      and against such other risks or hazards as  Beneficiary  from time to time
      reasonably may designate in an amount equal to one hundred  percent (100%)
      of the  then-current  "full  replacement  cost" of the  Improvements,  the
      Fixtures, and the Personalty, without deduction for physical depreciation;
      (ii) rental income insurance  against loss of income in an amount equal to
      twelve  (12)  months  rental  and  taxes  and  other   operating   expense
      reimbursements or payments at then-current income levels; (iii) Commercial
      General  Liability   insurance   including  broad  form  property  damage,
      contractual liability and personal injury coverage, with a combined single
      limit and general aggregate in such amounts as are reasonably  approved by
      Beneficiary;   (iv)  "Builders   Risk"   insurance   during  any  material
      construction,  repair,  replacement,   renovation  or  alteration  of  the
      Improvements,  in such amounts as are reasonably  approved by Beneficiary;
      (v) boiler and machinery  insurance  covering  boilers and other  pressure
      vessels,  the air  conditioning  system,  high  pressure  piping and other
      machinery and equipment  required for the operation of the Property;  (vi)
      Workers' Compensation Insurance with employer's liability endorsement; and
      (vii) such other insurance,  and in such amounts, as may from time to time
      be reasonably  required by  Beneficiary,  except that Trustor shall not be
      required to  maintain  earthquake  insurance  and shall not be required to
      maintain  flood  insurance on any Property  that lies outside the 100 year
      flood zone.

      B. The  policies of  insurance  required by this Deed of Trust  shall,  as
      applicable,  (i) be prepaid  annually and otherwise  satisfactory in form,
      substance and amount to Beneficiary and written with  financially  solvent
      companies  satisfactory  to  Beneficiary,  (ii)  name  Beneficiary  as  an
      additional  insured as its interest may appear,  (iii)  contain a Standard
      Lender's  Loss Payable  endorsement  and other  non-contributory  standard
      mortgagee   protection   clauses   acceptable  to   Beneficiary,   and  at
      Beneficiary's  option, a waiver of subrogation rights by the insurer, (iv)
      contain an  agreement  by the insurer that the policy shall not be amended
      or canceled  without at least  thirty (30) days' prior  written  notice to
      Beneficiary,  and (v) shall contain such other  provisions as  Beneficiary
      deems  reasonably  necessary or desirable  to protect its  interests.  Any
      policies  containing a coinsurance clause shall include a replacement cost
      endorsement  adequate  to ensure that the  coinsurance  clause is rendered
      inoperative.  Any Commercial General Liability insurance shall provide (A)
      for  severability  of  interests  or that acts or  omissions of one of the
      insureds  or  additional  insureds  shall not  reduce  or affect  coverage
      available to any other  insured or additional  insured,  and (B) that such
      insurance is primary and  noncontributing  with any  insurance  carried by
      Beneficiary or Trustee.

      C. In the  event a  blanket  policy  is  submitted  to  satisfy  Trustor's
      obligations   under  this   PARAGRAPH  3.2,  in  addition  to  such  other
      requirements  set forth herein,  Trustor  shall  deliver to  Beneficiary a
      certificate from such insurer indicating that Beneficiary is covered under
      such policy as required by this  PARAGRAPH  3.2, and  evidencing  that the
      amount and coverages of such insurance  applicable to the Property  comply
      with the requirements of this PARAGRAPH 3.2.

      D. Trustor shall furnish evidence,  satisfactory to Beneficiary,  that (i)
      all  insurance   requirements   (including   provisions   for  waivers  of
      subrogation) set forth in the Leases or any other agreements affecting the
      Property shall have been  satisfied by each party thereto;  (ii) Trustor's
      insurance  coverage is sufficient  (assuming the total  destruction of the
      Property) to permit Trustor to rebuild the  Improvements  (including basic
      tenant  improvements) and to replace the Fixtures and Personalty in such a
      manner as to enable the  Property  to be  operable  and  rentable as it is
      currently  rented and  operated;  and (iii) each  tenant,  required by the
      terms of its Lease to  maintain  insurance  on its  leased  premises,  has
      caused  Beneficiary  to be named as an  additional  insured  or loss payee
      under such insurance policies.

      E.  Self-insurance  (other  than the  applicable  deductibles  approved by
      Beneficiary) shall not satisfy the requirements of this PARAGRAPH 3.2.

      F. All of  Trustor's  right,  title and interest in and to all policies of
      property  insurance  and any  unearned  premiums  paid  thereon are hereby
      assigned (to the fullest extent  assignable) to Beneficiary who shall have
      the right, but not the obligation,  to assign the same to any purchaser of
      the Property at any foreclosure sale.

      G. Not less than  thirty  (30) days  prior to the  expiration  date of any
      policy  furnished  pursuant to this PARAGRAPH  3.2,  Trustor shall provide
      Beneficiary  with  duplicate  originals  or  certified  copies of  renewal
      policies  together with evidence  satisfactory to Beneficiary of Trustor's
      payment of the applicable premiums.

3.3.  MAINTENANCE,  WASTE AND REPAIR.  Trustor will (i) maintain the Property in
good order and condition; (ii) promptly make, or cause to be made, all necessary
structural  and  non-structural  repairs to the Property;  (iii) not diminish or
materially  alter the  Improvements,  or erect any new buildings,  structures or
building   additions  on  the  Land,   without  the  prior  written  consent  of
Beneficiary;  (iv) not remove or permit to be  removed  any of the  Fixtures  or
Personalty  from the Property  without the prior written  consent of Beneficiary
unless replaced by articles of equal suitability and value owned by Trustor free
and clear of any lien or security interest;  and (v) not permit any waste of the
Property  or make any  change  in the use  thereof,  nor do or permit to be done
thereon anything, that may in any way impair the security of this Deed of Trust.

3.4. IMPOSITIONS;  IMPOUNDS.  Trustor will pay all Impositions when due. Trustor
will  deliver  to  Beneficiary,  within  seven (7) days after  demand  therefor,
receipts  showing the payment of any  Impositions.  Upon the  occurrence  of the
first monetary or material  non-monetary Event of Default (including an Event of
Default under Paragraph  6.1.A(viii)  hereof),  and continuing until twelve (12)
consecutive  calendar  months  have  elapsed  following  cure of such  Event  of
Default,  Trustor will pay monthly to Beneficiary an amount equal to one-twelfth
(1/12th) of the annual cost of Impositions  together with an amount equal to the
estimated  next  premiums  for hazard  and other  required  insurance.  Upon the
occurrence of any subsequent monetary or material  non-monetary Event of Default
(including an Event of Default under Paragraph 6.1.A(viii) hereof), Trustor will
pay such amounts monthly to Beneficiary  until the Indebtedness is paid in full.
These funds will be held by Beneficiary without interest and will be released to
Trustor for payment of Impositions and insurance  premiums,  or directly applied
to such costs by Beneficiary, as Beneficiary may elect.

3.5.  COMPLIANCE WITH LAW. Trustor will promptly and faithfully  comply with and
perform all present and future Laws and Restrictions.

3.6.  BOOKS AND RECORDS AND OTHER INFORMATION.

      A.  Trustor,  without  expense  to  Beneficiary,  will  maintain  full and
      complete  books of  account  and  records  reflecting  the  results of the
      operations  of  the  Property  in  accordance   with  generally   accepted
      accounting  principles,  and will  furnish  or cause  to be  furnished  to
      Beneficiary such information concerning the financial condition of Trustor
      and the Property as Beneficiary shall reasonably request, including annual
      audited  financial  statements and an annual  operating  statement for the
      Property and annual audited financial statements for the Principal Parties
      and, to the extent such  statements are not in the public domain,  but may
      reasonably  be  obtained  by  Trustor,   for  the  Major   Tenants.   Upon
      Beneficiary's reasonable request, Beneficiary shall have the right, at all
      reasonable  times  and upon  reasonable  notice,  to audit  the  books and
      records of Trustor.  If such audit  discloses  a variance of five  percent
      (5%) or more in income or expenses entered in such books and records,  the
      cost of such audit shall be paid by Trustor.

      B.  Trustor  will  furnish  to  Beneficiary,  within  seven (7) days after
      written request therefor,  all information that Beneficiary may reasonably
      request  concerning  the  Property  or the  performance  by Trustor of the
      Obligations.

      C. Trustor shall keep at either its principal  place of business or at the
      offices at the Property,  and make available to Beneficiary  during normal
      business hours, as-built plans and specifications or, if unavailable,  the
      final set of plans and  specifications  from which the  Improvements  were
      constructed  ("As-Builts"),  certified by a licensed architect or licensed
      contractor as true, correct and complete As-Builts.

3.7. FURTHER  ASSURANCES.  Trustor,  at any time upon the reasonable  request of
Beneficiary,  will at Trustor's  expense,  execute,  acknowledge and deliver all
such additional  papers and  instruments  (including a declaration of no setoff)
and perform all such further acts as may be reasonably  necessary to perform the
Obligations and, as Beneficiary deems necessary, to preserve the priority of the
lien of this Deed of Trust and to carry out the purposes of the Loan Documents.

3.8. LITIGATION.  Trustor will promptly give notice in writing to Beneficiary of
any  litigation  or other event or  occurrence  which might result in a Material
Adverse Change.

3.9. INSPECTION OF PROPERTY.  Trustor hereby grants to Beneficiary,  its agents,
employees, consultants and contractors, the right to enter upon the Property for
the purpose of making any and all  inspections,  reports,  tests,  inquiries and
reviews as Beneficiary (in its sole and absolute  discretion) deems necessary to
assess  the then  current  condition  of the  Property,  or for the  purpose  of
performing any of the other acts Beneficiary is authorized to perform  hereunder
upon 72 hours  prior  notice to Trustor,  except  that such notice  shall not be
required (i) if an Event of Default  shall have  occurred and remain  uncured or
(ii) in the event of an emergency.  Trustor shall cooperate with  Beneficiary to
facilitate such entry and the  accomplishment of such purposes.  All costs, fees
and expenses  (including those of  Beneficiary's  legal counsel and consultants)
incurred  by  Beneficiary  with  respect to such  inspections,  reports,  tests,
inquiries and reviews shall be paid by Trustor to Beneficiary upon demand, shall
accrue interest at the Secondary  Interest Rate until paid, and shall be secured
by this Deed of Trust.

3.10. CONTEST. Notwithstanding the provisions of PARAGRAPHS 3.4 AND 3.5, Trustor
may, at its expense, upon written notice to Beneficiary, contest the validity or
application  of  any  Impositions  or  Laws  and   Restrictions  by  appropriate
administrative or legal proceedings  promptly initiated and diligently conducted
in good faith,  provided that (i)  Beneficiary is reasonably  satisfied that the
priority of this Deed of Trust shall be maintained  and neither the Property nor
any part thereof or interest therein will be in danger of being sold, forfeited,
or lost as a result of such  contest,  and (ii) if the  amount of the  contested
Imposition or the cost to comply with the  contested  Laws and  Restrictions  is
likely to exceed One Million  Dollars  ($1,000,000.00)  if decided  adversely to
Trustor,  or if an Event of Default has occurred or occurs and remained uncured,
Trustor  shall have  posted a bond or  furnished  such other  security as may be
reasonably required from time to time by Beneficiary.

3.11. ADDITIONAL INFORMATION.  Trustor will furnish to Beneficiary, within seven
(7)  days  after  written  request  therefor,   any  and  all  information  that
Beneficiary may reasonably request concerning the Property or the performance by
Trustor of the Obligations.

3.12.  PREPAYMENT.  Trustor may prepay the Loan only on the terms and conditions
set forth in the Note and Trustor shall pay  Beneficiary  prepayment  charges in
respect of any prepayment,  whether voluntary or involuntary, as required by and
on the terms and conditions set forth in the Note.

3.13. FIRPTA CERTIFICATE.  In the event of any Transfer by Trustor of its rights
hereunder or of any interest in the Property otherwise permitted under this Deed
of Trust,  the transferee  shall,  as an additional  condition to such Transfer,
under  penalty of  perjury,  execute and deliver to  Beneficiary  a  certificate
concerning  the  non-foreign  status  of  Trustor  substantially  in the form of
PARAGRAPH 2.7 hereof.  Nothing in this paragraph  shall be deemed a modification
or  waiver  of any  other  provision  of any of  the  Loan  Documents  limiting,
prohibiting  or  otherwise  relating  to any  Transfer  of any  interest  in the
Property or Trustor.

3.14. TAX SERVICE  CONTRACT.  So long as any Loan Document remains in effect, at
Trustor's  sole expense,  Beneficiary  shall be furnished tax service  contracts
issued by a tax reporting agency satisfactory to Beneficiary.

3.15. TRUSTOR'S OBLIGATIONS WITH RESPECT TO LEASE OF CISCO Systems. In the event
that Cisco Systems  ("Cisco")  exercises the right of first offer or purchase of
the Property  covered by its Lease (the "Cisco  Property"),  Trustor shall cause
Cisco to deposit the proceeds of such sale payable by Cisco to an escrow account
under the  control of  Beneficiary  established  with a title  company  mutually
acceptable  to Trustor and  Beneficiary.  Unless an Event of Default  shall have
occurred and remain uncured,  Trustor may, following consummation of the sale of
the Cisco  Property  to Cisco,  (i) elect to  replace  the Cisco  Property  with
substitute   collateral  pursuant  to  Paragraph  4.3  hereof,  in  which  event
Beneficiary  shall  release  the  proceeds  to  Trustor  concurrently  with  the
consummation of the  substitution  of collateral,  or (ii) apply the proceeds to
prepay the  Indebtedness,  which  payment shall  constitute a Prepayment  Amount
under the Note.


                                    ARTICLE 4
                               NEGATIVE COVENANTS

Trustor hereby covenants to and agrees as follows:

4.1.  RESTRICTIVE  USES.  Trustor will not initiate,  join in, or consent to any
change in the current use of the  Property or in any zoning  ordinance,  private
restrictive  covenant,   assessment  proceedings  or  other  public  or  private
restriction limiting or restricting the uses that may be made of the Property or
any part thereof or in any way change the boundaries of the Property without the
prior written consent of Beneficiary.

4.2.  PROHIBITED TRANSFERS.

      A. Except as  otherwise  provided  in  PARAGRAPHS  4.2.B and 4.2.C  below,
      Trustor shall not participate in, and shall not cause,  allow or otherwise
      permit, a Transfer without the prior written consent of Beneficiary, which
      consent  may be given or  withheld  for any  reason  (or for no reason) or
      given conditionally (including a requirement that the permitted transferee
      assume in writing,  in form and substance  satisfactory  to Beneficiary in
      its  sole  discretion,   all  of  Trustor's  Obligations  under  the  Loan
      Documents,   the  Hazardous   Substances  Agreement  and  the  Certificate
      Regarding  Distribution of Loan Proceeds and Indemnity Agreement and agree
      to be  bound  thereby),  as  determined  by  Beneficiary  in its  sole and
      absolute discretion, and any default, failure to observe, or breach of the
      provisions of this  PARAGRAPH 4.2 shall  constitute an immediate  Event of
      Default  hereunder  and,  at the option of  Beneficiary,  Beneficiary  may
      accelerate the Indebtedness whereby the entire Indebtedness (including any
      Prepayment  Premium)  shall  become  immediately  due  and  payable.   Any
      assumption of Trustor's obligations hereunder shall not, however,  release
      any Loan  Party  from  any  liability  under  the  Loan  Documents  or the
      Hazardous  Substances  Agreement.   This  provision  shall  not  apply  to
      transfers of title or interest  under any will or testament or  applicable
      law of descent or transfers of limited  partnership  interests in Trustor.
      Consent to any such Transfer by  Beneficiary  shall not be deemed a waiver
      of  Beneficiary's  right to require  such consent to any further or future
      Transfers.

      B.  Notwithstanding  the foregoing,  the following  Transfers shall not be
      prohibited and shall not,  except as otherwise  provided in this PARAGRAPH
      4.2.B, require Beneficiary's consent, or if effectuated in accordance with
      the terms and conditions of this PARAGRAPH  4.2.B,  constitute an Event of
      Default under the Loan Documents: (i) the Transfer of shares of any Person
      which is a publicly  traded company with its shares listed and traded on a
      national exchange in the United States of America, so long as the Transfer
      is  executed  in the  ordinary  course of trading  of such  shares on such
      exchange,  (ii)  the  issuance  by  any  Loan  Party  of  publicly  traded
      securities,   whether  or  not  in  connection  with  the  acquisition  of
      properties; (iii) the conversion of Operating Partnership Units in Trustor
      to common stock in Mission West, or in a Person that is a publicly  traded
      company  with its shares  listed and traded on a national  exchange in the
      United  States of America,  subject to the  satisfaction  of the  Transfer
      Conditions; (iv) the issuance of Operating Partnership Units in Trustor in
      connection  with the  acquisition of  properties,  so long as the proposed
      transaction  complies  with all ERISA  requirements  contained in the Loan
      Documents  and,  if a  change  occurs  in  the  identity  of  the  Persons
      controlling the major decision making  management  level of Trustor and/or
      Mission West in connection with such transaction,  subject additionally to
      the  satisfaction  of the other  Transfer  Conditions;  (v) subject to the
      satisfaction of the Transfer  Conditions,  the acquisition of Mission West
      through merger,  tender offer, exchange offer or sale of substantially all
      the assets of Mission West (each a "Mission West Merger  Transaction") and
      (vi) subject to the satisfaction of the Transfer Conditions, the merger of
      Mission  West  Properties,  a  California  corporation,  with  and  into a
      wholly-owned  subsidiary named Mission West  Properties,  Inc., a Maryland
      corporation  ("MWP,  Inc."),  provided  that  MWP,  Inc.  has no assets or
      liabilities immediately prior to the merger and provided further that such
      merger  follows the plan set forth in Trustor's  current S-4  Registration
      Statement  in the section  titled "The  Reincorporation  Merger." The term
      "Transfer Conditions" shall mean each of the following  requirements:  (A)
      Beneficiary  receives at least thirty (30) days' prior  written  notice of
      the Transfer;  (B) there is no Event of Default  under the Loan  Documents
      (or event which with the passage of time or the giving of notice, or both,
      would be an Event of Default)  which has occurred and is  continuing;  (C)
      the proposed transaction complies with all ERISA requirements contained in
      the Loan Documents  (including  receipt by Beneficiary of such evidence as
      it may  require in its sole  discretion  to  determine  that the  proposed
      Transfer  is not and would not  render the Loan a  prohibited  transaction
      under  ERISA);  (D) if deemed  applicable  by  Beneficiary,  the  proposed
      transferee shall have signed a written  assumption  agreement with respect
      to the Loan  Documents in form and substance  acceptable to Beneficiary in
      its sole discretion;  (E) the proposed  transferee shall have provided all
      information about the proposed transferee requested by Beneficiary; (F) in
      the event of a  Mission  West  Merger  Transaction,  Beneficiary  shall be
      satisfied with the  creditworthiness,  good character and reputation,  and
      demonstrated  ability and experience (by itself or through its manager) in
      the ownership, operation, and leasing of property similar to the Property,
      of the successor entity to Mission West, except that in no event shall the
      net worth  (excluding for purposes of this  calculation,  the Property) of
      the successor  entity based on market value, as determined by Beneficiary,
      be less than  $250,000,000.00;  and (G) payment by Trustor or the proposed
      transferee of (1) all costs and expenses  incurred by Beneficiary  for the
      processing  of the Transfer,  including a processing  fee as determined by
      Lender,  (2) any documentary  stamp taxes,  intangibles  taxes,  recording
      fees,  and other  costs  and  expenses  required  in  connection  with any
      assumption  agreement and any modification of the Loan Documents,  and (3)
      all other costs and expenses  (including  attorneys' fees and expenses for
      Beneficiary's  staff attorneys and outside  counsel) of the preparation of
      any assumption agreement and any modification of the Loan Documents.

      C.  Notwithstanding  PARAGRAPHS  4.2.A  and  4.2.B  above,  if no Event of
      Default or event  which with the  passage of time or the giving of notice,
      or both,  would  constitute  an  Event  of  Default  has  occurred  and is
      continuing, Beneficiary shall, upon thirty (30) days prior written request
      by Trustors, consent to a one-time Transfer of the entire Property if: (i)
      the proposed transferee is a Person which, in the judgment of Beneficiary,
      has  financial  capability  and  creditworthiness  of  Trustors,  and  the
      reputation  and  experience in the  ownership,  operation,  management and
      leasing of similar  properties,  equal to or greater  than  Mission  West,
      except that under no  circumstances  shall the proposed  transferee have a
      net worth (excluding, for purposes of this calculation, the Property) less
      than $100,000,000.00; (ii) at the time of Transfer the Loan to Value Ratio
      does  not  exceed  fifty-five   percent  (55%);   (iii)  Trustors  pay  to
      Beneficiary  a fee equal to  one-half  of one  percent  (1/2%) of the then
      outstanding   principal   balance  of  the  Loan   concurrently  with  the
      consummation of such Transfer;  (iv) at Beneficiary's option,  Beneficiary
      has received an  endorsement  to  Beneficiary's  title policy at Trustors'
      expense,  which endorsement states that this Deed of Trust remains a first
      and prior lien against the Property  (excluding the  Personalty);  (v) the
      Debt  Service  Coverage  Ratio is at least 1.85 to 1.00 for the  preceding
      twelve (12) month period and Beneficiary  receives  satisfactory  evidence
      that such Debt  Service  Coverage  Ratio will be  maintained  for the next
      succeeding  twelve (12) months;  (vi) the transferee in writing  expressly
      assumes the Obligations under the Loan Documents,  and under the Hazardous
      Substances Agreement, and executes any other documents reasonably required
      by  Beneficiary,  and such  assumptions  and all such other  documents are
      satisfactory  in form and  substance  to  Beneficiary;  (vii)  Beneficiary
      reasonably  approves  the form and content of all Transfer  documents  and
      Beneficiary is furnished  with a certified  copy of the recorded  Transfer
      documents; (viii) the proposed transferee complies with ERISA and delivers
      the ERISA  certification  and  indemnification  agreements  required under
      PARAGRAPH 9.18 hereof;  and (ix) Trustors or the proposed  transferee pays
      all  reasonable  fees,  costs and  expenses  incurred  by  Beneficiary  in
      connection  with such  Transfer,  including  all legal  (both for  outside
      counsel and Beneficiary's staff attorneys),  accounting,  title insurance,
      documentary  stamp or transfer taxes,  intangible  taxes,  mortgage taxes,
      recording  fees,  and  appraisal  fees,  whether or not such  Transfer  is
      actually consummated.

4.3. SUBSTITUTION OF SECURITY.  Notwithstanding PARAGRAPH 4.2 above, and so long
as there is no Event of Default  under the Loan  Documents  (or event which with
the  passage  of time or the  giving of  notice,  or both,  would be an Event of
Default which has occurred and is continuing),  Beneficiary  shall,  upon thirty
(30) days' prior written request by Trustor, subject to the conditions set forth
below,  release from the lien of this Deed of Trust the entirety of any Eligible
Transfer Property identified in EXHIBIT B hereto:

      (i) Trustor  grants to Beneficiary a first lien in the fee simple title of
   a replacement property (the "Substitute  Property") owned one hundred percent
   (100%) by the Trustor which owns the Eligible Transfer Property that is being
   released  (which  lien  shall be in the form of this Deed of Trust  with only
   such changes  thereto as Beneficiary may  incorporate,  from time to time, in
   the form of deed of trust then utilized by Beneficiary in securing commercial
   mortgage  loans  similar  to the Loan to address  developments  in the law of
   concern to  Beneficiary in  implementing  its mortgage  lending  practices in
   California)  (the  "Substitute  Deed of  Trust")  and  Trustor  executes  and
   delivers to Beneficiary such approvals,  opinions,  documents and other items
   as Beneficiary may reasonably  request in connection with the substitution of
   security for, and the perfection of Beneficiary's  security  interest in, the
   Substitute Property;

      (ii)  Beneficiary  shall not be required to release any Eligible  Transfer
   Property if the sum of the aggregate Original Allocated Loan Amount (as shown
   on EXHIBIT B hereto) of the Eligible Transfer Property for which a release is
   sought and of all other  Eligible  Transfer  Properties  which  prior to such
   release  have been  released  from the lien of this  Deed of  Trust,  exceeds
   $65,000,000.00;

      (iii)  Trustor  pays  Beneficiary  a  non-refundable  servicing  fee  (the
   "Servicing  Fee") at the time of  Trustor's  request in the amount of Fifteen
   Thousand  Dollars  ($15,000.00)  for each  Eligible  Transfer  Property  that
   Trustor is requesting to be released from the lien of this Deed of Trust;

      (iv)  Trustor  pays  to  Beneficiary  at  the  time  the  substitution  of
   collateral is effected a release fee (the "Release Fee") equal to one-half of
   one percent  (1/2%) of the Original  Allocated  Loan  Amount,  as adjusted to
   reflect  amortization  of principal  that has  occurred  from the date of the
   recording of this Deed of Trust to the date the substitution of collateral is
   effected,  for each Eligible  Transfer Property that Trustor is requesting to
   be  released  from  the  lien of this  Deed of  Trust,  except  that  (A) the
   Servicing  Fee shall be credited  against the Release  Fee,  and (B) under no
   circumstances  shall the  Release  Fee exceed  $75,000.00  for each  Eligible
   Transfer Property;

      (v)  Beneficiary  receives a 1970 form ALTA title  policy  (including  any
   endorsements thereto deemed necessary by Beneficiary) insuring the first lien
   priority of the Substitute Deed of Trust encumbering the Substitute Property,
   subject only to the lien of real property taxes not delinquent and such other
   exceptions  to  title  approved  by  Beneficiary  in its  sole  and  absolute
   discretion,   with  liability  coverage  in  the  amount  of  the  Loan,  and
   Beneficiary  receives such other title assurances as it may request to ensure
   that its first lien priority in the Property that is not being  released will
   continue unaffected by the release of the Eligible Transfer Property;

      (vi) the  Substitute  Property shall satisfy,  in  Beneficiary's  sole and
   absolute discretion, Beneficiary's then-current mortgage lending requirements
   and underwriting criteria in all respects, including requirements relating to
   environmental and hazardous materials matters,  provided, except that without
   limiting the foregoing,  under no circumstances  shall a Substitute  Property
   qualify for substitution for an Eligible Transfer  Property  hereunder unless
   the Substitute Property is, in Beneficiary's sole judgment, at least equal to
   the  corresponding  Eligible  Transfer  Property  in  each  of the  following
   respects:  (A)  appraised  value,  (B)  stability  of cash flow,  taking into
   consideration  weighted  average  lease  maturities,  (C)  tenant  credit and
   quality and diversification,  (D) building quality and  diversification,  and
   (E) location quality and diversification;

      (vii) the Substitute Property shall be a research and development building
   (or  buildings  contiguous  to each other)  located in the San  Francisco Bay
   Area, as defined by Beneficiary;

      (viii) the Debt Service  Coverage  Ratio for the Property is at least 1.50
   to 1.00 for the  preceding  twelve  month  period  and  Beneficiary  receives
   satisfactory   evidence  that  such  Debt  Service  Coverage  Ratio  will  be
   maintained for the next succeeding twelve (12) months;

      (ix) Beneficiary receives  satisfactory  evidence that the prospective Net
   Operating Income for the Substitute  Property for the succeeding  twelve (12)
   months  will be not less  than one  hundred  ten  percent  (110%) of the then
   current Net Operating
   Income of the Eligible Transfer Property.

      (x) Beneficiary determines, in its sole and absolute discretion,  that the
   release and  substitution  of  collateral  would not result in a violation of
   ERISA,  including the ERISA  provisions  contained in this Deed of Trust, and
   Trustor delivers such  certifications  and other documents as Beneficiary may
   request in connection therewith; and

      (xi) Trustor pays all reasonable  fees,  costs,  and expenses  incurred by
   Beneficiary  in  connection  with  the  proposed  release  and  substitution,
   including  all legal (for both  Beneficiary's  staff  attorneys  and  outside
   counsel),  accounting, title insurance,  documentary stamps taxes, intangible
   taxes, mortgage taxes, recording fees, and appraisal fees, whether or not the
   release and/or substitution is actually consummated.

4.4. NO  COOPERATIVE OR  CONDOMINIUM.  Trustor shall not operate the Property or
permit the Property to be operated as a cooperative  or condominium or otherwise
such that the  tenants  or  occupants  participate  in  ownership,  control,  or
management of the Property.

4.5. PARTNERSHIP OR OPERATING AGREEMENT.  Trustor, if a partnership or a limited
liability   company,   will  not  terminate,   permit  the  termination  of,  or
substantially amend the partnership  agreement or operating  agreement,  without
Beneficiary's prior written consent. As used herein, "substantially amend" means
any amendment, modification, or alteration that would cause or result in (i) the
change of control of the  Trustor,  (ii) the change of the name of the  Trustor,
(iii) the change of the nature of the  business or  operations  of the  Trustor,
(iv) the revocation or purported  repudiation of any  Obligations of the Trustor
under  the Loan  Documents,  (v) the  termination  of the lien  and/or  security
interest  in and to the  Property  under the Loan  Documents  or (vi) a Material
Adverse Change. Nothing in this PARAGRAPH 4.5 shall affect any other Obligations
of Trustor under the Loan Documents,  the Hazardous  Substances Agreement or the
Certificate Regarding Distribution of Loan Proceeds and Indemnity Agreement.

                                    ARTICLE 5
                           CASUALTIES AND CONDEMNATION

5.1.  INSURANCE AND CONDEMNATION PROCEEDS.

      A.  Trustor  shall  notify  Beneficiary  in writing  immediately  upon the
      occurrence  of any loss or damage by fire or other  casualty to any of the
      Property  or  upon  obtaining   knowledge  of  the   commencement  of  any
      proceedings for condemnation of any of the Property.  Beneficiary shall be
      entitled  to (i)  participate  in any such  condemnation  proceedings  and
      Trustor  from time to time will  deliver to  Beneficiary  all  instruments
      reasonably necessary to permit such participation,  and (ii) if the repair
      of the loss or  casualty  is  reasonably  estimated  to cost more than One
      Million  Dollars  ($1,000,000.00)  or if an Event of  Default  shall  have
      occurred and remain uncured  (either,  an "Insurance  Event"),  settle and
      adjust all insurance  claims  relative to any such damage or  destruction,
      deducting from any insurance  proceeds the amount of all expenses incurred
      by  Beneficiary  in connection  with any such  settlement  or  adjustment.
      Notwithstanding  anything  to the  contrary  contained  in  any  insurance
      policies if an Insurance  Event  pertains,  all  proceeds  paid to Trustor
      under any insurance policies required to be maintained by Trustor pursuant
      to PARAGRAPH 3.2 or otherwise relating to the Property,  and any insurance
      proceeds  received  by Trustor  under  insurance  policies  maintained  by
      tenants pursuant to a lease obligation,  shall immediately be delivered to
      Beneficiary.

      B. If  Beneficiary  elects or is  required to make  insurance  proceeds or
      condemnation  awards available for repair or  reconstruction,  Beneficiary
      shall, through a disbursement  procedure established by Beneficiary,  make
      available  to  Trustor  the  net  amount  of  all  insurance  proceeds  or
      condemnation   awards   received  by   Beneficiary   after   deduction  of
      Beneficiary's  reasonable costs and expenses, if any, in collection of the
      same  (the  "Net  Proceeds").  Beneficiary  shall  make  the Net  Proceeds
      available  to  Trustor  for  repair or  reconstruction  if (i) no Event of
      Default or event,  which with the passage of time or the giving of notice,
      or both,  would  constitute  an  Event  of  Default  has  occurred  and is
      continuing;  (ii)  Beneficiary  is satisfied that (A) the Property can and
      will be  repaired  or  reconstructed  within  18  months  from the date of
      damage,  destruction  or  condemnation  to the  condition  of the Property
      immediately prior to the damage, destruction or condemnation in accordance
      with plans and specifications  approved by Beneficiary,  (B) the repair or
      reconstruction  shall be  finally  completed  on a date  which is at least
      twenty-four  (24) months prior to the maturity of the Loan, and (C) Leases
      which are terminated or terminable as a result of such damage, destruction
      or  condemnation  cover an aggregate  rentable square footage of less than
      ten percent (10%) of the total rentable  square  footage  contained in the
      Property  subject to the  condemnation  or  casualty at the closing of the
      Loan;  (iii) Trustor shall have entered into a  construction  contract for
      completion of the repair or reconstruction with a general contractor which
      is acceptable in all respects to the Beneficiary (which general contractor
      may be a Loan Party or an affiliate thereof, provided that such Loan Party
      or affiliate  shall be required to obtain three (3)  competitive  sub-bids
      for each  component of the work of repair or  reconstruction  if the total
      cost of completion of the repair or reconstruction is likely to exceed One
      Million  Dollars  [$1,000,000.00]),  and which  contract must in any event
      include  provisions for retention of not less than ten percent (10%) until
      full and final, lien-free completion of the repair or reconstruction and a
      final completion date which is at least 24 months prior to the maturity of
      the Loan, and (iv) in Beneficiary's  reasonable judgment, the security for
      the Loan has not been  materially  impaired  as a result  of such  damage,
      destruction or condemnation.  In the event  Beneficiary  elects not, or is
      not  required,   to  make  the  Net  Proceeds   available  for  repair  or
      reconstruction,  Beneficiary,  at its  sole  option,  may  apply  the  Net
      Proceeds in payment of the  Indebtedness  or in  satisfaction of any other
      Obligation in such order as Beneficiary may determine provided that if (1)
      Beneficiary applies the Net Proceeds to the Indebtedness and the amount of
      Net Proceeds equals the Original  Allocated Loan Amount for the particular
      Property that suffered the casualty, or (2) in the event such Net Proceeds
      are less than the Original Allocated Loan Amount, Trustor pays Beneficiary
      the  difference  between  the  Original  Allocated  Loan  Amount  and  Net
      Proceeds,  in either such event,  then, so long as no Event of Default has
      occurred  and remains  uncured,  Beneficiary  shall  release the  affected
      Property  which  suffered the casualty from the lien of this Deed of Trust
      and the other Loan Documents. A payment by Trustor to Beneficiary pursuant
      to the foregoing clause shall not be considered a Prepayment  Amount under
      the  Note.  Notwithstanding  any  provision  of this  Deed of Trust to the
      contrary, under no circumstance shall Beneficiary be obligated to make any
      portion of the Net Proceeds available for repair or reconstruction  unless
      at the time of the request for any  disbursement  it has determined in its
      reasonable  discretion that the repair or reconstruction  can be completed
      at a cost (which  cost shall  include  all  payments  coming due under the
      terms of the Loan) which does not exceed the  aggregate  of the  remaining
      Net Proceeds and any funds deposited with Beneficiary by Trustor.

      C. The Net Proceeds  and any  additional  funds  deposited by Trustor with
      Beneficiary,  plus any loss of rental income insurance proceeds which have
      been deposited with  Beneficiary or which the carrier has  acknowledged to
      be payable,  shall constitute  additional  security for the Loan.  Trustor
      shall  execute,  deliver,  file and/or  record,  at its own expense,  such
      documents and instruments as Beneficiary  requires to grant to Beneficiary
      a perfected, first priority security interest in the Net Proceeds and such
      additional funds.

5.2. ADDITIONAL PROVISIONS RELATING TO CONDEMNATION.  Trustor,  immediately upon
obtaining  knowledge of the commencement of any proceedings for the condemnation
of the entire Property or any material part thereof, will notify Trustee and the
Beneficiary of the pendency of such  proceedings.  Trustee and  Beneficiary  may
participate in any such  proceedings  and Trustor from time to time will deliver
to  Beneficiary  all  instruments   requested  by  Beneficiary  to  permit  such
participation.  In the  event of such  condemnation  proceedings,  the  award or
compensation  payable is hereby  assigned  to and shall be paid to  Beneficiary.
Beneficiary  shall be under no  obligation  to  question  the amount of any such
award or  compensation  and may  accept the same in the amount in which the same
shall  be  paid.  In  any  such  condemnation  proceedings,  Beneficiary  may be
represented by counsel  selected by Beneficiary,  the cost of such counsel to be
borne by Trustor.  The proceeds of any award or  compensation so received shall,
at the  option  of  Beneficiary,  either be  applied  to the  prepayment  of the
Indebtedness or  satisfaction of any Obligation,  or be paid over to the Trustor
for  restoration  of the  Improvements  in  accordance  with the  provisions  of
PARAGRAPH 5.1. Trustor hereby  unconditionally and irrevocably waives all rights
of a property owner under Section  1265.225(a)  of the California  Code of Civil
Procedure, or any successor statute providing for the allocation of condemnation
proceeds between a property owner and a lien holder.

                  EVENTS OF DEFAULT AND REMEDIES OF BENEFICIARY

6.1.  EVENTS OF DEFAULT.

      A. It  shall  constitute  an  Event  of  Default  hereunder  if any of the
      following events shall occur and Beneficiary,  by written notice delivered
      to Trustors,  declares an Event of Default:  (i) Trustor shall fail to pay
      within  five (5) days of the date  when due any part of the  Indebtedness;
      (ii)  Trustor  shall  fail to timely  observe,  perform or  discharge  any
      Obligation,  other than as described in PARAGRAPHS 6.1.A.(I), (III), (IV),
      (V), (VI), (VII) AND (VIII),  and any such failure shall remain unremedied
      for thirty  (30) days (the  failure  under this  clause  (ii)  hereinafter
      referred  to as the  "Grace  Period"),  after  notice  to  Trustor  of the
      occurrence of such failure; provided, however, that Beneficiary may extend
      the Grace Period up to ninety (90) days if (A)  Beneficiary  determines in
      good faith that (1) such  failure  cannot be cured within the Grace Period
      but can be cured within ninety (90) days, (2) no lien or security interest
      created by the Loan Documents would be impaired prior to the completion of
      such  cure,  and (3)  Beneficiary's  immediate  exercise  of any  remedies
      provided  hereunder  or by law is not  necessary  for  the  protection  or
      preservation of the Property or Beneficiary's  security  interest therein,
      and (B) Trustor shall immediately  commence and diligently pursue the cure
      of such default;  (iii) Trustor,  as lessor or sublessor,  as the case may
      be,  shall  assign the Rents and  Proceeds  without  first  obtaining  the
      written  consent  of  Beneficiary;  (iv)  default  by  Trustor  after  the
      expiration of all applicable  grace or cure periods under any agreement to
      which Trustor is a party,  other than the Loan Documents,  which agreement
      relates to the  borrowing  of money by Trustor  from any Person,  and such
      default might give rise to a Material  Adverse Change or adversely  affect
      the  security for the Loan;  (v) any  representation  or warranty  made by
      Trustor  in,  under  or  pursuant  to the  Loan  Documents  was  false  or
      misleading  in  any  material  respect  as  of  the  date  on  which  such
      representation or warranty was made or deemed remade; (vi) any of the Loan
      Documents  shall cease to be in full force and effect or be declared  null
      and void, or shall cease to constitute  valid and subsisting  liens and/or
      valid and perfected security interests in and to the Property,  or Trustor
      shall  contest or deny in writing  that it has any  further  liability  or
      obligation  under any of the Loan  Documents;  (vii) the  occurrence  of a
      Material  Adverse  Change;  or  (viii)  any  default  by  Trustor  on  its
      obligations  under the Lease between Trustor,  as successor in interest to
      Berg & Berg Enterprises,  Inc. ("Berg & Berg"), a California  corporation,
      as "Lessor," and Avnet,  Inc., a New York corporation,  as "Lessee," dated
      October  27,  1997,   as  amended  (the  "Avnet   Lease"),   to  construct
      improvements  described  therein  as  "Phase  II" in the time  and  manner
      required by the Avnet Lease.

      B.  It  shall  constitute  an  Event  of  Default  hereunder  without  the
      requirement of any notice by  Beneficiary  if any of the following  events
      shall occur:  (i) Trustor,  any other Loan Party,  any general  partner or
      managing  member of any Loan  Party  which is a  partnership  or a limited
      liability  company,  as the case may be,  any  parent  company of any such
      general partner or managing  member,  or any owner of the Property (each a
      "Principal  Party,"  and  collectively,  the  "Principal  Parties")  shall
      generally  not pay its debts as they  become due or shall admit in writing
      its  inability to pay its debts,  or shall have made a general  assignment
      for the benefit of creditors;  (ii) any Principal Party shall commence any
      case,  proceeding  or other action  seeking  reorganization,  arrangement,
      adjustment,  liquidation,  dissolution  or  composition of it or its debts
      under any law relating to bankruptcy, insolvency, reorganization or relief
      of debtors,  or seeking to have an order for relief entered  against it as
      debtor, or seeking appointment of a receiver,  trustee, custodian or other
      similar official for it or for all or any substantial part of its property
      (collectively,  a "Proceeding");  (iii) any Principal Party shall take any
      action to  authorize  any of the actions set forth above in clauses (i) or
      (ii); (iv) any Proceeding shall be commenced  against any Principal Party,
      and such  Proceeding  (A)  results  in the  entry of an order  for  relief
      against it which is not fully stayed  within seven (7) business days after
      the entry  thereof or (B) remains  undismissed  for a period of forty-five
      (45) days; (v) any Principal Party shall liquidate,  dissolve or otherwise
      terminate their corporate, limited liability company, partnership or other
      entity  organizational  structure  without  the prior  written  consent of
      Beneficiary;  or (vi) failure to timely observe,  perform or discharge any
      provision of PARAGRAPH 4.2 hereof or the occurrence of a Transfer  without
      Beneficiary's  prior  written  consent,  when  such  consent  is  required
      pursuant to PARAGRAPH 4.2.

6.2.  REMEDIES.

      A. Upon the  occurrence  of any Event of Default,  Beneficiary  may at any
      time  declare all of the  Indebtedness  to be due and payable and the same
      shall  thereupon  become  immediately  due and payable,  together with all
      payments due in accordance with the terms of the Note, without any further
      presentment,  demand,  protest or notice of any kind.  Beneficiary may, in
      its sole  discretion,  also do any of the  following:  (i) in  person,  by
      agent, or by a Receiver,  without regard to the adequacy of security,  the
      solvency of Trustor or the condition of the Property,  without  obligation
      so to do and without notice to or demand upon Trustor, enter upon and take
      possession of the Property, or any part thereof, in its own name or in the
      name of  Trustee  and do any acts which  Beneficiary  deems  necessary  to
      preserve the value or marketability of the Property;  sue for or otherwise
      collect  the Rents and  Proceeds,  and  apply  the  same,  less  costs and
      expenses of operation and collection, including reasonable attorneys' fees
      (including  court  costs,  expert  witness  fees,  document   reproduction
      expenses,  costs of exhibit  preparation,  courier  charges,  postage  and
      communication  expenses),  against the  Obligations,  all in such order as
      Beneficiary  may determine;  appear in and defend any action or proceeding
      purporting  to affect,  in any manner  whatsoever,  the  Obligations,  the
      security  hereof or the rights or powers of Beneficiary  or Trustee;  pay,
      purchase  or  compromise  any  encumbrance,  charge  or  lien  that in the
      judgment of  Beneficiary  or Trustee is prior or superior  hereto;  and in
      exercising any such powers, pay necessary expenses, employ counsel and pay
      reasonable  attorneys' fees (including  court costs,  expert witness fees,
      document  reproduction  expenses,  costs of exhibit  preparation,  courier
      charges, postage and communication  expenses);  (ii) as a matter of strict
      right and without notice to Trustor or anyone claiming under Trustor,  and
      without  regard to the then value of the  Property,  apply ex PARTE to any
      court  having  jurisdiction  to appoint a Receiver  to enter upon and take
      possession  of the  Property,  and  Trustor  hereby  waives  notice of any
      application therefor,  provided a hearing to confirm such appointment with
      notice  to  Trustor  is set  within  the time  required  by law (any  such
      Receiver  shall have all the powers  and  duties of  Receivers  in like or
      similar  cases and all the  powers and  duties of  Beneficiary  in case of
      entry as provided herein, and shall continue as such and exercise all such
      powers until the date of confirmation of sale, unless such receivership is
      sooner  terminated);  (iii)  commence an action to foreclose  this Deed of
      Trust in any manner provided hereunder or by law; (iv) with respect to any
      Personalty,  proceed  as  to  both  the  real  and  personal  property  in
      accordance with Beneficiary's  rights and remedies in respect of the Land,
      or proceed to sell said  Personalty  separately  and without regard to the
      Land in accordance with  Beneficiary's  rights and remedies as to personal
      property;  and/or (v) deliver to Trustee a written  declaration of default
      and demand for sale, and a written notice of default and election to cause
      the Property to be sold,  which notice Trustee or Beneficiary  shall cause
      to be duly filed for record.

      B. If Trustor  shall at any time fail to perform or comply with any of the
      Obligations  under any of the Loan Documents or any other  agreement that,
      under the terms of this Deed of Trust,  Trustor is  required  to  perform,
      then  Beneficiary  may,  in its sole  discretion:  (i)  make any  payments
      hereunder  or  thereunder  payable  by Trustor  and take out,  pay for and
      maintain  any of the  insurance  policies  provided for herein or therein;
      and/or  (ii)  after the  expiration  of any  applicable  grace  period and
      subject to Trustor's right of contest of certain Obligations  specifically
      granted  hereby,  perform  any such other acts  thereunder  on the part of
      Trustor to be performed and enter upon the Property for such purpose.

      C. Should  Beneficiary elect to foreclose by exercise of the power of sale
      herein contained,  Beneficiary shall notify Trustee and shall deposit with
      Trustee this Deed of Trust and the Note and such  receipts and evidence of
      expenditures made and secured hereby as Trustee may require.  Upon receipt
      of such  notice from  Beneficiary,  Trustee  shall  cause to be  recorded,
      published  and  delivered to Trustors such notice of default and notice of
      sale as then  required  by law and by this Deed of Trust.  Trustee  shall,
      without  demand  on  Trustors,  after  lapse  of such  time as may then be
      required by law and after  recordation of such notice of default and after
      notice of sale having been given as required by law,  sell the Property at
      the time and place of sale fixed by it in said notice of sale, either as a
      whole,  or in  separate  lots or  parcels  or items as  Beneficiary  shall
      determine,  and in such  order as  Beneficiary  may  determine,  at public
      auction  to the  highest  bidder  for cash in lawful  money of the  United
      States  payable  at the  time  of  sale.  Trustee  shall  deliver  to such
      purchaser  or  purchasers  thereof its good and  sufficient  deed or deeds
      conveying  the  property so sold,  but without any  covenant or  warranty,
      express or  implied.  The  recitals  in such deed of any  matters or facts
      shall  be  conclusive  proof  of the  truthfulness  thereof.  Any  Person,
      including Trustor,  Trustee or Beneficiary,  may purchase at such sale and
      Trustor hereby covenants to warrant and defend the title of such purchaser
      or purchasers. After deducting all costs, fees and expenses of Trustee and
      of this Trust,  including  costs of evidence of title in  connection  with
      sale, Trustee shall apply the proceeds of sale in the following  priority,
      to payment of: (i) first,  all sums expended  under the terms hereof,  not
      then repaid,  with accrued  interest at the Secondary  Interest Rate; (ii)
      second,  all other sums then secured hereby;  and (iii) the remainder,  if
      any, to the person or persons legally entitled  thereto.  Beneficiary may,
      in its sole discretion, designate the order in which the Property shall be
      offered  for sale or sold  through a single  sale or  through  two or more
      successive  sales, or in any other manner  Beneficiary  deems to be in its
      best  interest.  If  Beneficiary  elects  more  than  one  sale  or  other
      disposition of the Property,  Beneficiary may at its option cause the same
      to be conducted simultaneously or successively, on the same day or at such
      different days or times and in such order as Beneficiary may deem to be in
      its best interests,  and no such sale shall terminate or otherwise  affect
      the lien of this Deed of Trust on any part of the  Property  not then sold
      until all Indebtedness  secured hereby has been fully paid. If Beneficiary
      elects to  dispose of the  Property  through  more than one sale,  Trustor
      shall pay the costs and  expenses of each such sale of its interest in the
      Property and of any  proceedings  where the same may be made.  Trustee may
      postpone  the  sale  of  all  or  any  part  of  the  Property  by  public
      announcement  at such  time  and  place of  sale,  and  from  time to time
      thereafter may postpone such sale by public announcement at the time fixed
      by the preceding  postponement,  and without further notice make such sale
      at the  time  fixed by the  last  postponement;  or  Trustee  may,  in its
      discretion,  give a new notice of sale.  Beneficiary  may rescind any such
      notice of default at any time before  Trustee's sale by executing a notice
      of rescission and recording the same. The recordation of such notice shall
      constitute a cancellation  of any prior  declaration of default and demand
      for sale and of any  acceleration of maturity of Indebtedness  affected by
      any prior declaration or notice of default. The exercise by Beneficiary of
      the right of rescission  shall not constitute a waiver of any default then
      existing or subsequently  occurring, or impair the right of Beneficiary to
      execute other  declarations  of default and demand for sale, or notices of
      default  and of election to cause the  Property to be sold,  or  otherwise
      affect the Note or this Deed of Trust,  or any of the rights,  obligations
      or remedies of Beneficiary or Trustee hereunder.

      D. In the event of a sale of the Property,  or any part  thereof,  and the
      execution  of a deed  therefor,  the recital  therein of  default,  and of
      recording  the notice of default and notice of sale,  and of the elapse of
      the required time (if any) between the  recording  and the notice,  and of
      the  giving  of notice of sale,  and of a demand  by  Beneficiary,  or its
      successors or assigns,  that such sale should be made, shall be conclusive
      proof of such default, recording,  election, elapse of time, and giving of
      such notice,  and that the sale was  regularly and validly made on due and
      proper demand by Beneficiary,  its successors or assigns. Any such deed or
      deeds with such recitals therein shall be effective and conclusive against
      Trustor,  its successors and assigns,  and all other Persons.  The receipt
      for the purchase  money  recited or contained in any deed  executed to the
      purchaser as aforesaid  shall be  sufficient  discharge to such  purchaser
      from all  obligations  to see to the proper  application  of the  purchase
      money.

      E. All  remedies of  Beneficiary  provided for herein are  cumulative  and
      shall be in addition to any and all other rights and remedies  provided in
      the other Loan  Documents or by law,  including  any right of offset.  The
      exercise of any right or remedy by Beneficiary  hereunder shall not in any
      way  constitute  a cure or waiver of default  hereunder  or under the Loan
      Documents,  or invalidate  any act done pursuant to any notice of default,
      or prejudice Beneficiary in the exercise of any of its rights hereunder or
      under the Loan Documents.

      F. All sums expended by Trustee or  Beneficiary  in the exercise of any of
      their  rights or  remedies  under this Deed of Trust,  and all  reasonable
      costs  and  expenses  incurred  in  connection   therewith  shall  (i)  be
      immediately  due and  payable  on  demand,  (ii)  accrue  interest  at the
      Secondary  Interest Rate from the date of expenditure by Beneficiary,  and
      (iii) be added to the Indebtedness and secured by the Loan Documents prior
      to any right, title or interest in or claim upon the Property attaching or
      accruing subsequent to the lien of this Deed of Trust.

                                    ARTICLE 7
                      SECURITY AGREEMENT AND FIXTURE FILING

7.1. GRANT OF SECURITY INTEREST. Trustor hereby grants to Beneficiary a security
interest  in and to all  Trustor's  right,  title  and  interest  now  owned  or
hereafter acquired in and to the Personalty and the Fixtures (collectively,  the
"Collateral").

7.2.  REMEDIES.  This Deed of Trust  constitutes a security  agreement under the
California  Uniform  Commercial  Code with  respect to the  Collateral  in which
Beneficiary is hereby granted a security interest. In addition to the rights and
remedies  provided under this Deed of Trust,  Beneficiary  shall have all of the
rights and remedies of a secured party under the California  Uniform  Commercial
Code as well as all other  rights and  remedies  available  at law or in equity.
Trustor shall execute and deliver on demand,  and  irrevocably  constitutes  and
appoints  Beneficiary the  attorney-in-fact of Trustor to, at Trustor's expense,
execute,  deliver  and,  if  appropriate,  to file with the  appropriate  filing
officer or office,  such  instruments as  Beneficiary  may request or require in
order to impose,  perfect or continue  the  perfection  of, the lien or security
interest  created  hereby.   Upon  the  occurrence  of  any  Event  of  Default,
Beneficiary  shall  have the right (i) to cause any of the  Collateral  which is
personal  property  to be sold at any one or more  public  or  private  sales as
permitted  by  applicable  law  and  to  apply  the  proceeds   thereof  to  the
Indebtedness  or the  satisfaction  of any  Obligation  and (ii) to apply to the
Indebtedness or the satisfaction of any Obligation any Collateral which is cash,
negotiable  documents or chattel paper. Any such disposition may be conducted by
an employee or agent of  Beneficiary or Trustee.  Any Person,  including both of
Trustor and  Beneficiary,  shall be eligible to purchase any part or all of such
Personalty at any such disposition.

7.3. EXPENSES. Expenses of retaking, holding, preparing for sale, selling or the
like,  pertaining to the Collateral  shall be borne by Trustor and shall include
Beneficiary's  and  Trustee's  reasonable  attorneys'  fees and  legal  expenses
(including court costs,  expert witness fees,  document  reproduction  expenses,
costs  of  exhibit  preparation,  courier  charges,  postage  and  communication
expenses). Trustor, upon demand of Beneficiary shall assemble the Collateral and
make it available to Beneficiary at the Property, a place which is hereby deemed
to be reasonably  convenient to Beneficiary and Trustor.  Beneficiary shall give
Trustor at least ten (10) days'  prior  written  notice of the time and place of
any public  sale or other  disposition  of the  Collateral  or of the time after
which any private sale or any other intended disposition is to be made. Any such
notice sent to Trustor in the manner  provided for the mailing of notices herein
is hereby deemed to be reasonable notice to Trustor.

7.4. FIXTURE FILING. This Deed of Trust covers certain goods which are or are to
become  fixtures  related to the Land and constitutes a fixture filing under the
California  Uniform  Commercial Code with respect such goods executed by Trustor
as debtor in favor of Beneficiary as secured party.

7.5. WAIVERS. Trustor waives (i) any right to require Beneficiary to (A) proceed
against any Person,  (B) proceed against or exhaust any Collateral or (C) pursue
any other  remedy in its power;  and (ii) any  defense  arising by reason of any
disability or other defense of Trustor or any other Person,  or by reason of the
cessation  from any cause  whatsoever  of the  liability of Trustor or any other
Person.  Until the Indebtedness  shall have been paid in full, Trustor shall not
have any right to  subrogation,  and  Trustor  waives any right to  enforce  any
remedy  which  Beneficiary  now has or may  hereafter  have  against  Trustor or
against any other Person and waives any benefit of and any right to  participate
in any Collateral or security whatsoever now or hereafter held by Beneficiary.

If and to the extent that any Trustor is or may ever be deemed to be a guarantor
of any Obligations of any of the other Trustors,  each Trustor hereby waives all
rights and defenses arising out of an election of remedies by Beneficiary,  even
though that election of remedies, such as a nonjudicial foreclosure with respect
to security for a guaranteed  obligation,  has extinguished  Trustor's rights of
subrogation and reimbursement against the principal, if any, by the operation of
Section 580d of the Code of Civil  Procedure or otherwise.  Notwithstanding  the
foregoing,  and in addition thereto and without limiting the generality thereof,
Trustor hereby absolutely and irrevocably waives any and all (1) rights which it
may have or may now or hereafter acquire by way of subrogation, reimbursement or
indemnity against any or all of the other Trustors by virtue of any payment made
under the Loan  Documents or otherwise  in  connection  with the Loan and/or the
Property,  and (2)  other  claims  or  rights  against  any or all of the  other
Trustors relating to the Loan Documents or the Obligations.

    TRUSTOR ACKNOWLEDGES AND AGREES THAT PURSUANT TO THE FOREGOING PARAGRAPH, IT
HAS  WAIVED,  AMONG  OTHER  SPECIFIC  RIGHTS  THAT MAY BE  GRANTED TO TRUSTOR ON
ACCOUNT OF ANY STATUS  TRUSTOR MAY BE DEEMED TO HAVE AS A SURETY OR GUARANTOR OF
ANOTHER  TRUSTOR  AT LAW OR IN  EQUITY,  ITS  RIGHTS,  IF ANY,  TO  SUBROGATION,
REIMBURSEMENT  AND/OR INDEMNITY  AGAINST ANY OR ALL OF THE OTHER TRUSTORS.  SUCH
WAIVER INCLUDES A WAIVER OF TRUSTOR'S RIGHTS THROUGH SUBROGATION,  AFTER PAYMENT
MADE BY SUCH TRUSTOR UNDER THE LOAN  DOCUMENTS,  TO BE  SUBSTITUTED  IN PLACE OF
BENEFICIARY  WITH RESPECT TO THE OBLIGATIONS OF THE OTHER TRUSTORS SUCH THAT THE
TRUSTOR COULD SUCCEED TO BENEFICIARY'S RIGHTS, REMEDIES AND/OR SECURITY RELATING
TO SUCH  OBLIGATIONS  AND ASSERT A CLAIM  AGAINST  THE OTHER  TRUSTORS.  CERTAIN
AUTHORITIES  HAVE  DETERMINED  THAT,  IN THE  ABSENCE  OF AN  EFFECTIVE  WAIVER,
PARTICULAR ACTIONS OF A LENDER THAT IMPAIR OR DESTROY A GUARANTOR'S  SUBROGATION
RIGHTS COULD PROVIDE A GUARANTOR  WITH A DEFENSE TO THE PAYMENT AND  PERFORMANCE
OF ITS OBLIGATIONS UNDER ITS GUARANTY. BY WAY OF EXAMPLE, BUT NOT OF LIMITATION,
COURTS HAVE HELD THAT, ABSENT AN EFFECTIVE WAIVER, A GUARANTOR MAY BE EXONERATED
FROM ITS  OBLIGATIONS  UNDER A GUARANTY IF A LENDER  COMPROMISES OR EXTINGUISHES
SUCH GUARANTOR'S SUBROGATION RIGHTS BY ELECTING TO FORECLOSE NON-JUDICIALLY,  BY
POWER OF SALE, ON REAL PROPERTY  SECURITY THEREBY INVOKING THE DEFICIENCY BAR OF
CALIFORNIA  CODE OF CIVIL  PROCEDURE  SECTION  580D.  TRUSTOR  AGREES  THAT SUCH
DEFENSES  ARE  INAPPLICABLE  TO  TRUSTOR  AS A  POSSIBLE  GUARANTOR  IN LIGHT OF
TRUSTOR'S  IRREVOCABLE  WAIVER OF SUBROGATION,  REIMBURSEMENT  AND/OR  INDEMNITY
RIGHTS  AGAINST  ANY OR ALL OF THE OTHER  TRUSTORS  SET  FORTH IN THE  FOREGOING
PARAGRAPH AND THAT NO ACTION BY BENEFICIARY IN ENFORCING ITS RIGHTS AND REMEDIES
AGAINST  ANY OR ALL OF  THE  OTHER  TRUSTORS  OR  OTHERWISE  MAY  COMPROMISE  OR
EXTINGUISH  SUCH RIGHTS BECAUSE EACH SUCH RIGHT HAS BEEN  IRREVOCABLY  WAIVED BY
TRUSTOR HEREUNDER.  TRUSTOR HEREBY ACKNOWLEDGES THAT IT HAS BEEN NOTIFIED OF THE
NATURE  OF ALL OF ITS  RIGHTS  AND  DEFENSES  AS A  POSSIBLE  GUARANTOR  AND HAS
KNOWINGLY AND WITH THE ADVICE OF LEGAL  COUNSEL  WAIVED SUCH RIGHTS AND DEFENSES
AS SET FORTH  HEREIN.  EACH OF THE  WAIVERS  CONTAINED  HEREIN  WERE  SEPARATELY
BARGAINED FOR.

                                         INITIALS: __________

                                    ARTICLE 8
                 ASSIGNMENT OF RENTS AND PROCEEDS AND AGREEMENTS

8.1.  ASSIGNMENT OF RENTS AND PROCEEDS.  Trustor absolutely and  unconditionally
assigns and  transfers the Rents and Proceeds to  Beneficiary,  whether now due,
past due or to become due, and gives to and confers upon  Beneficiary the right,
power and  authority to collect such Rents and  Proceeds,  and apply the same to
the  Indebtedness or the  satisfaction of any  Obligation.  Trustor  irrevocably
appoints  Beneficiary  its agent to, at any time,  demand,  receive  and enforce
payment, to give receipts, releases and satisfactions, and to sue, either in the
name of Trustor or in the name of Beneficiary,  for all such Rents and Proceeds.
Neither the  foregoing  assignment of Rents and Proceeds to  Beneficiary  or the
exercise  by  Beneficiary  of any of its rights or  remedies  under this Deed of
Trust  shall  be  deemed  to make  Beneficiary  a  "mortgagee-in-possession"  or
otherwise  responsible  or liable in any manner with  respect to the Property or
the use,  occupancy,  enjoyment or operation of all or any part thereof,  unless
and until Beneficiary,  in person or by its own agent, assumes actual possession
thereof,  nor shall  appointment  of a Receiver for the Property by any court at
the request of  Beneficiary  or by agreement  with Trustor or the entering  into
possession  of the  Property by such  Receiver be deemed to make  Beneficiary  a
"mortgagee-in-possession"  or otherwise responsible or liable in any manner with
respect to the Property or the use,  occupancy,  enjoyment or operation thereof.
Concurrently  with the  execution of this Deed of Trust,  Trustor has  executed,
delivered and recorded the Assignment of Leases in favor of Beneficiary.  In the
event of any  inconsistency  between the terms and  provisions of this ARTICLE 8
and the terms and  provisions  of the  Assignment  of Leases,  the latter  shall
control.

8.2. ASSIGNMENT OF AGREEMENTS.  Trustor hereby sells, assigns,  transfers,  sets
over and delivers to Beneficiary all of Trustor's  right,  title and interest in
and to any and all agreements,  contracts, reports, surveys, plans, drawings and
governmental approvals whatsoever pertaining to the operation of the Property or
to the construction of the Improvements, as the same may be amended or otherwise
modified  from time to time  (collectively,  the  "Agreements").  The  foregoing
assignment  encompasses  the  right  of  Trustor  to  (i)  terminate  any of the
Agreements,  (ii)  perform or compel  performance  and  otherwise  exercise  all
remedies under the Agreements,  and (iii) collect and receive all sums which may
become due Trustor or which Trustor may now or shall  hereafter  become entitled
to demand or claim, under the Agreements.

8.3.  REVOCABLE  LICENSE.  Notwithstanding  anything to the  contrary  contained
herein or in the  Note,  so long as no Event of  Default  shall  have  occurred,
Trustor  shall have a license to collect  all Rents and  Proceeds  and all other
sums which may become  payable to  Trustor  under the  Agreements,  and to first
apply the same to the payment or performance of the Obligations as and when due.
Upon the  occurrence  of (i) the first Event of Default,  and  continuing  until
twelve (12)  consecutive  calendar  months have elapsed  following  cure of such
Event of Default,  and (ii) any subsequent Event of Default,  Beneficiary  shall
have the right,  on written  notice to Trustor,  (A) to terminate and revoke the
license  herein  granted to Trustor,  and (B) then or thereafter to exercise and
enforce any and all of its rights and remedies  provided in this ARTICLE 8 or by
law or at equity.

8.4.  NONRESPONSIBILITY.  The acceptance by Beneficiary of the assignments  with
all the rights,  powers,  privileges and authority so granted shall not obligate
Beneficiary  to assume any  obligations  in respect of the Rents and Proceeds or
under the  Agreements  or take any action  thereunder  or to expend any money or
incur any expense or perform or discharge any  obligation,  duty or liability in
respect  of the Rents and  Proceeds  or under the  Agreements  or to assume  any
obligation or responsibility for the nonperformance of the provisions thereof by
Trustor.

                                    ARTICLE 9
                                  MISCELLANEOUS

9.1. SUCCESSOR TRUSTEE.  Beneficiary may remove Trustee or any successor trustee
at any time or times and  appoint a  successor  trustee by  recording  a written
substitution  in each county  where the  Property  is  located,  or in any other
manner permitted by law.

9.2.  NO WAIVER.  No failure by  Beneficiary  to insist  upon  strict,  full and
complete  (i)  payment  when  due of any  portion  of the  Indebtedness  or (ii)
performance  of any  Obligation,  nor  failure to  exercise  any right or remedy
hereunder, shall constitute a waiver of any such failure to pay or breach of any
such Obligation, or of the later exercise of such right or remedy.

9.3.  ABANDONMENT.  Any and all Personalty that upon foreclosure of the Property
is owned by Trustor and is used in connection with the operation of the Property
shall be deemed at the option of  Beneficiary to have become on such date a part
of the Property and abandoned to Beneficiary in its then condition.

9.4. NOTICES. All notices or other written communications hereunder or under any
other Loan  Documents  shall be given in writing  (i) in person or by  facsimile

9.10.  ENTIRE  AGREEMENT.  The  Loan  Documents  and  the  Hazardous  Substances
Agreement set forth the entire  understanding  between  Trustor and  Beneficiary
relative  to the Loan and the same  shall  not be  amended  except  by a written
instrument  duly  executed by each of Trustor  and  Beneficiary.  The  foregoing
notwithstanding,  the terms and the conditions of the Application  shall survive

additional security for any obligations secured hereby, it may enforce the terms
thereof or otherwise  realize  upon the same,  at its option,  either  before or
concurrently  herewith  or after a sale is made  hereunder,  and may  apply  the
proceeds upon the  Indebtedness  without  affecting the status of or waiving any
right to exhaust all or any other  security,  including the security  hereunder,
and  without  waiving  any  breach  or  default  or any  right or power  whether
exercised hereunder or contained herein or in any such other security.

9.13. SUITS TO PROTECT  PROPERTY.  Trustor shall appear in and defend any action
or proceeding  purporting to affect the security of the Deed of Trust, any other
Loan Documents, or of any additional or other security for the Obligations,  the

reasonable   attorneys'  fees,  court  costs,   expert  witness  fees,  document
reproduction expenses,  costs of exhibit preparation,  courier charges,  postage
and  communication  expenses,  in any  action  or term,  covenant  or  condition
proceeding in which  Beneficiary  and/or  Trustee may appear or be made a party,
including foreclosure or other proceeding commenced by those claiming a right to
any part of the  Property in any action to  partition  or condemn all or part of
the Property,  whether or not pursued to final judgment,  and in any exercise of
the  power  of  sale  contained  herein,  whether  or not the  sale is  actually

required to deliver to Trustor under applicable law.

9.15. USURY. In the event that Beneficiary, or a court of competent jurisdiction
in a final, non-appealable judgment, determines that any charge, fee or interest
paid or agreed to be paid in connection  with the Loan may, under the applicable
usury laws, cause the interest rate on the Loan to exceed the maximum  permitted
by law,  then such  charges,  fees or interest  shall be reduced and any amounts
actually paid in excess of the maximum interest  permitted by such laws shall be
applied by Beneficiary to reduce the outstanding  Principal Balance of the Loan.
The parties  intend that Trustor  shall not be required to pay, and  Beneficiary
shall not be entitled to collect,  interest in excess of the maximum  legal rate
permitted under the applicable usury laws.

9.16. PUBLICITY. Beneficiary, at its expense, may publicize the financing of the
Property.

9.17.  INFORMATION  REPORTING UNDER IRS SECTION 6045(E). Any information returns
or  certifications  that must be filed with the Internal  Revenue Service and/or
provided to other  parties  pursuant to Internal  Revenue Code  Section  6045(e)
shall be prepared,  filed by and sent to the appropriate  parties by Trustor. To
the extent permitted by law, Beneficiary shall have no responsibility to perform
such  services;  provided  however,  that upon demand  Trustor  shall  reimburse
Beneficiary for any costs incurred by Beneficiary in doing so and shall also pay
such fee as Beneficiary may reasonably and lawfully request.  Beneficiary shall,
where  requested  by  Trustor,  promptly  supply  Trustor  with all  information
pertaining to Beneficiary reasonably required by Trustor to prepare and file any
such return or certification.

9.18.  ERISA.

      A. Beneficiary  represents and warrants to Trustor that, as of the date of
      this Deed of Trust and  throughout  the term of the  Loan,  the  source of
      funds from which  Beneficiary  extends  the Loan is its  General  Account,
      which is subject to the claims of its general creditors under state law.

      B. Trustor  represents and warrants to Beneficiary that, as of the date of
      this  Deed of Trust  and  covenants  that,  until  the Loan and all  other
      Obligations  are paid and  performed in full,  (i) Trustor is not and will
      not become an  "employee  benefit  plan" as defined in Section 3(3) of the
      Employee  Retirement  Income  Security Act of 1974, as amended  ("ERISA"),
      which is  subject  to Title I of ERISA,  and (ii) the assets of Trustor do
      not and will not constitute "plan assets" of one or more such plans within
      the meaning of 29 C.F.R. Section 2510.3-101.

      C. Trustor  represents and warrants to Beneficiary that, as of the date of
      this Deed of Trust (i)  Trustor is not a  "governmental  plan"  within the
      meaning of Section 3(32) of ERISA and (ii) transactions by or with Trustor
      are not subject to state statutes  regulating  investment of and fiduciary
      obligations with respect to governmental plans.

      D. Trustor  shall  deliver to  Beneficiary  such  certifications  or other
      evidence  from time to time until the Loan and all other  Obligations  are
      paid and  performed  in full,  as  requested  by  Beneficiary  in its sole
      discretion,  and Trustor hereby  warrants and  represents to  Beneficiary,
      that (i)  Trustor is not an  "employee  benefit  plan" or a  "governmental
      plan";  and (ii)  Trustor  is not  subject  to state  statutes  regulating
      investments and fiduciary  obligations with respect to governmental plans;
      and (iii) one or more of the following  circumstances  is true: (A) equity
      interests in Trustor are publicly offered  securities,  within the meaning
      of 29 C.F.R. Section  2510.3-101(b)(2);  (B) less than twenty-five percent
      (25%)  of all  equity  interests  in  Trustor  are held by  "benefit  plan
      investors" within the meaning of 29 C.F.R. Section  2510.3-101(f)(2);  (C)
      Trustor  qualifies as an "operating  company" or a "real estate  operating
      company" within the meaning of 29 C.F.R. Section  2510.3-101(c) or (e); or
      (D) no equity  interest in Trustor is held  directly or  indirectly  by an
      employee benefit plan subject to ERISA.

      E. In addition  to any other  breach by Trustor of any  provision  of this
      PARAGRAPH 9.18, any of the following shall  constitute an Event of Default
      entitling  Beneficiary to exercise any and all remedies to which it may be
      entitled under the Loan Documents:  (i) the failure of any  representation
      or  warranty  made by  Trustor  under this  PARAGRAPH  9.18 to be true and
      correct  in  all  respects,   (ii)  the  failure  of  Trustor  to  provide
      Beneficiary  with the  written  certifications  and  evidence  referred to
      above, or (iii) the  consummation by Trustor of a transaction  which would
      cause the Deed of Trust or any exercise of Beneficiary's  rights under the
      Loan  Documents to constitute a non-exempt  prohibited  transaction  under
      ERISA or a violation of a state  statute  regulating  governmental  plans,
      subjecting  Beneficiary  to liability for violation of ERISA or such state
      statute.

      F.  Trustor  shall  indemnify,  protect  and defend  and hold  Beneficiary
      harmless from and against all liability,  loss,  claims,  damage,  cost or
      expense,  including  attorneys'  fees,  court costs,  expert witness fees,
      document  reproduction  expenses,  costs of exhibit  preparation,  courier
      charges,  postage and  communication  expenses,  and costs incurred in the
      investigation,  defense and  settlement  of claims and losses  incurred in
      correcting any prohibited transaction or in the sale of a prohibited loan,
      and in obtaining any individual  prohibited  transaction  exemption  under
      ERISA  that  may be  required,  in  Beneficiary's  sole  discretion,  that
      Beneficiary  may incur,  directly or indirectly,  as a result of a default
      under  PARAGRAPH  9.18.E.  This indemnity  shall survive any  termination,
      satisfaction or foreclosure of the Deed of Trust.

      G.  Anything in  PARAGRAPH  4.2 or  elsewhere in this Deed of Trust to the
      contrary  notwithstanding,  no Transfer of any direct or indirect interest
      in Trustor shall be permitted which would negate Trustor's representations
      in this  PARAGRAPH  9.18 or cause this Deed of Trust (or any  exercise  of
      Beneficiary's  rights under the Loan  Documents) to constitute a violation
      of any provision of ERISA or of any applicable state statute  regulating a
      governmental plan, as determined in the sole discretion of Beneficiary.

      H.  Anything in  PARAGRAPH  4.2 or  elsewhere in this Deed of Trust to the
      contrary  notwithstanding,  no  Transfer of the  Property or any  interest
      therein including a junior lien or leasehold interest,  shall be permitted
      which  would cause this Deed of Trust (or any  exercise  of  Beneficiary's
      rights under the Loan Documents) to constitute a violation of ERISA or any
      applicable state statute  regulating a governmental plan, as determined in
      the sole discretion of Beneficiary.

      I.  Anything in this Deed of Trust to the  contrary  notwithstanding,  not
      less than fifteen  (15) days before  consummation  of a Transfer,  Trustor
      shall obtain from the proposed  transferee or lienholder a  representation
      to Beneficiary  in form and substance  satisfactory  to  Beneficiary  that
      PARAGRAPH  9.18.D will be true after the  transfer;  and further  provided
      that any proposed  lienholder  agrees that any direct or indirect transfer
      of its lien or any  interest  herein will be  governed  by this  PARAGRAPH
      9.18.

9.19.  INDEMNIFICATION AND DEFENSE.

      A. Trustor will indemnify,  defend,  protect and hold  Beneficiary and its
      agents harmless from and against all liability, loss, claims, damage, cost
      or expense  (including  reasonable  attorneys' fees,  court costs,  expert
      witness   fees,   document   reproduction   expenses,   costs  of  exhibit
      preparation,  courier charges,  postage and  communication  expenses) that
      Beneficiary  might incur in connection with the making or administering of
      the Loan, the enforcement of any of Beneficiary's rights or remedies under
      the Loan  Documents,  by reason of any  failure of any  representation  or
      warranty  made by  Trustor  or the  failure  of  Trustor  to  perform  any
      Obligation  or by reason or in defense  of any and all claims and  demands
      whatsoever that may be asserted against  Beneficiary  arising out of or in
      connection  with the  Property  or the Loan,  but which  shall not include
      claims,  liabilities,  damages, causes of action or costs arising from (1)
      Beneficiary's  and/or  any  participating  lender's  gross  negligence  or
      willful   misconduct  or  (2)  disputes   between   Beneficiary   and  any
      participating lender not arising from neglect,  willful misconduct,  or an
      act, omission or Event of Default by Trustor.

      B. Whenever,  under any Loan  Document,  Trustor is obligated to indemnify
      and/or defend Beneficiary,  or Trustor is obligated to defend or prosecute
      any  action  or  proceeding,  then  Beneficiary  shall  have the  right to
      participate in such  prosecution or defense using counsel of Beneficiary's
      choice,  and all costs and expenses  incurred by Beneficiary in connection
      with such  participation  (including  reasonable  attorneys'  fees,  court
      costs,  expert  witness fees,  document  reproduction  expenses,  costs of
      exhibit preparation,  courier charges, postage and communication expenses)
      shall be reimbursed by Trustor to  Beneficiary.  In addition,  Beneficiary
      shall  have the right to  approve  any  counsel  retained  by  Trustor  in
      connection  with  the  prosecution  or  defense  of  any  such  action  or
      proceeding  by Trustor.  Trustor shall give notice to  Beneficiary  of the
      initiation  of all  proceedings  prosecuted  or required to be defended by
      Trustor,  or which are  subject  to  Trustor's  indemnity  and/or  defense
      obligations,  under  this Deed of Trust,  promptly  after the  receipt  by
      Trustor of notice of the existence of any such proceeding, but in no event
      later than five (5) days thereafter.

      C. Should Beneficiary incur any liability,  loss, claim,  damage,  cost or
      expense required to be reimbursed by Trustor to Beneficiary hereunder, the
      amount thereof with interest thereon at the Secondary  Interest Rate shall
      constitute  part of the  Indebtedness,  shall be payable  by Trustor  upon
      demand and shall be secured by this Deed of Trust.

9.20.  DESTRUCTION OF NOTE. Trustor shall, if the Note is mutilated or destroyed
by any cause  whatsoever,  or otherwise lost or stolen and regardless of whether
due to the act or neglect of  Beneficiary  or  Trustee,  execute  and deliver to
Beneficiary in substitution  therefor a duplicate promissory note containing the
same terms and  conditions as the Note,  within ten (10) days after  Beneficiary
notifies Trustor of any such mutilation, destruction, loss or theft of the Note.
In such event,  Beneficiary shall be responsible for any payments Trustor may be
legally  required to make to any holder of the  original  promissory  note after
Trustor  has paid  Beneficiary  on a duplicate  note,  provided,  however,  that
Trustor  shall make no such  payments on the  original  promissory  note without
Beneficiary's  written consent and Trustor shall give Beneficiary written notice
of any request that may be made of Trustor to make such payment(s) within thirty
(30) days after Trustor has received any such request.

9.21. HEIRS AND ASSIGNS.  Subject to the restrictions on Transfers  contained in
this Deed of Trust,  this Deed of Trust and all other Loan  Documents  apply to,
inure to the benefit of, and bind all parties  hereto and thereto,  their heirs,
legatees, devisees, administrators, executors, successors and assigns.

9.22.  INTERPRETATION.  When the identity of the parties or other  circumstances
make it  appropriate,  the masculine  gender shall  include the feminine  and/or
neuter, and the singular number shall include the plural.  Specific  enumeration
of rights, powers and remedies of Trustee and Beneficiary and of acts which they
may do and of acts  Trustor  must do or not do shall  not  exclude  or limit the
general.  The headings of each Article and Paragraph are for  convenience and do
not limit or construe the contents of any provision  hereof.  The  provisions of
the Loan Documents and the Hazardous  Substances Agreement shall be construed as
a whole according to their common meaning, not strictly for or against any party
and consistent  with the provisions  herein  contained,  in order to achieve the
objectives  and  purposes  of such  documents.  Each party and its  counsel  has
reviewed and revised the Loan Documents and the Hazardous  Substances  Agreement
and  agree  that  the  normal  rule  of  construction  to the  effect  that  any
ambiguities are to be resolved  against the drafting party shall not be employed
in the  interpretation  of such document.  The use in the Loan Documents and the
Hazardous Substances Agreement of the words "including",  "such as", or words of
similar import when following any general term, statement or matter shall not be
construed  to limit  such  statement,  term or matter to the  specific  items or
matters,  whether or not language of non-limitation such as "without limitation"
or "but not  limited  to",  or words of similar  import are used with  reference
thereto,  but rather shall be deemed to refer to all other items or matters that
could reasonably fall within the broadest possible scope of such statement, term
or  matter.  The term  "Trustor"  shall  be  deemed  to refer to each and  every
Trustor, both individually and collectively,  when more than one Trustor exists,
and to the original Trustor, and its or their successors and assigns (whether or
not such  successor  or assign  assumed  the  Obligations  hereunder);  the term
"Beneficiary"  includes  the  Beneficiary  named  herein or any future  owner or
holder, including pledgee and participants, of the Note, or any other instrument
secured hereby, or any participation  therein;  and the term "Trustee"  includes
the original  Trustee and its  successors  and assigns.  The  references  to the
"Property"  shall be deemed to refer to all or any portion of the  Property  and
any interest  therein.  References to "foreclosure" and related phrases shall be
deemed  references to the  appropriate  procedure in connection  with  Trustee's
private  power  of  sale as well as any  judicial  foreclosure  proceeding  or a
conveyance in lieu of foreclosure.

9.23. INFORMATION TO THIRD PERSONS. If, at any time, Beneficiary desires to sell
or transfer, or grant a participation interest in, all or any portion of, or any
interest in, the Note or any other Loan  Document to any Person,  Trustor  shall
furnish in a timely  manner any and all  financial  information  concerning  the
Property and Leases,  and concerning  Trustor,  requested by Beneficiary or such
Person in connection with any such sale or transfer.

9.24.  COMMINGLING  OF  FUNDS.  Any  and  all  sums  collected  or  retained  by
Beneficiary   under  any  of  the  Loan  Documents   (including   insurance  and
condemnation  proceeds  and any  amounts  paid by Trustor to  Beneficiary  under
PARAGRAPH 3.4 hereof),  shall not be deemed to be held in trust, and Beneficiary
may commingle  such funds or proceeds  with its general  assets and shall not be
liable for the payment of any  interest or other return  thereon,  except to the
extent otherwise required by law.

9.25. CERTAIN OBLIGATIONS  UNSECURED.  Notwithstanding  anything to the contrary
set forth  herein  or any of the Loan  Documents,  this  Deed of Trust  does not
secure  the  following  obligations  (the  "Unsecured  Obligations"):   (i)  any
obligations  evidenced by or arising under the Hazardous  Substances  Agreement,
(ii) any other  obligations  in this  Deed of Trust or in any of the other  Loan
Documents to the extent that such other obligations  relate  specifically to the
presence on the Property of  Hazardous  Materials  (as defined in the  Hazardous
Substances  Agreement)  and are the same or have the same  effect  as any of the
obligations  evidenced by or arising under the Hazardous  Substances  Agreement,
and (iii) any obligations arising under the Certificate  Regarding  Distribution
of Proceeds and Indemnity  Agreement.  Any breach or default with respect to the
Unsecured   Obligations   shall  constitute  an  Event  of  Default   hereunder,
notwithstanding the fact that such Unsecured Obligations are not secured by this
Deed of  Trust.  Nothing  in this  section  shall,  in  itself,  impair or limit
Beneficiary's right to obtain a judgment in accordance with applicable law after
foreclosure for any deficiency in recovery of all  obligations  that are secured
by this Deed of Trust following foreclosure.

9.26 COSTS AND FEES.  All costs,  fees and expenses  incurred by  Beneficiary in
making,  administering  or collecting the Loan (including those of Beneficiary's
legal  counsel and  consultants,  court costs,  expert  witness  fees,  document
reproduction expenses, costs of exhibit preparation,  courier charges,  postage,
communication  expenses,  costs in  connection  with any  inspections,  reports,
tests,  inquiries and reviews,  condemnation  proceedings,  endorsements  to the
title policy,  actions or  proceedings in which  Beneficiary  and/or Trustee may
appear or be made a party,  foreclosure or other proceedings  commenced by those
claiming a right to any part of the Property or any action to  partition  all or
part of the Property,  whether or not pursuant to final judgment and exercise of
the  power  of  sale  contained  herein,  whether  or not the  sale is  actually
consummated)  and all sums expended by Trustee or Beneficiary in the exercise of
any of their  respective  rights or remedies under this Deed of Trust,  shall be
immediately due and payable by Trustor to Beneficiary upon demand,  shall accrue
interest at the Secondary Interest Rate from the date of expenditure until paid,
and shall be added to the  Indebtedness  secured by the Loan Documents  prior to
any right, title or interest in or claim upon the Property attaching or accruing
subsequent to the lien of this Deed of Trust.

9.27.  STANDARD OF APPROVAL;  COVENANT OF GOOD FAITH AND FAIR DEALING.  Whenever
Trustee or  Beneficiary  has been  specifically  granted a right to exercise its
business judgment,  or act, in a subjective manner,  with respect to any matter,
or the right to act in its sole and absolute discretion or sole judgment, or the
right to make a  subjective  judgment  under any  provision  of this  Agreement,
whether  or not  "objectively"  reasonable  under  the  circumstances,  any such
exercise  shall not be deemed  inconsistent  with any covenant of good faith and
fair dealing otherwise implied by law to be part of the Loan Documents.

9.28. EXHIBITS.  The following Exhibits, to which reference is made in this Deed
of Trust, are deemed incorporated into this Deed of Trust in their entirety:
           A    -    Property Description
           B    -    Eligible Transfer Properties

9.29  JOINT AND  SEVERAL  LIABILITY.  The  Obligations  are  joint  and  several
undertakings  of each of the Trustors,  and  Beneficiary may proceed against any
one or more of the Trustors  without waiving its right to proceed against any of
the other Trustors.

IN WITNESS WHEREOF, Trustors have caused this Deed of Trust to be executed as of
the day and year first above written.

                               TRUSTOR:

              CERTIFICATE REGARDING DISTRIBUTION OF LOAN PROCEEDS
                             AND INDEMNITY AGREEMENT


      THIS  CERTIFICATE  is made  as of  September  22,  1998  by  MISSION  WEST
PROPERTIES, L.P., a Delaware limited partnership,  MISSION WEST PROPERTIES, L.P.
I, a Delaware limited partnership,  MISSION WEST PROPERTIES, L.P. II, a Delaware
limited partnership,  and MISSION WEST PROPERTIES,  L.P. III, a Delaware limited
partnership,  each having offices at 10050 Bandley Drive, Cupertino,  California
95014 (each a "Borrower" and collectively,  "Borrowers"), to and for the benefit
of THE  PRUDENTIAL  INSURANCE  COMPANY  OF  AMERICA,  a New  Jersey  corporation
("Prudential"),  in  conjunction  with a loan (the "Loan") made or to be made by
Prudential  to Borrowers  in the amount of One Hundred  Thirty  Million  Dollars
($130,000,000.00) as more particularly  described in that certain First Mortgage
Loan   Application   dated  June  24,  1998  and  executed  by  Borrowers   (the
"Application").

      This  Certificate  is  made  with  respect  to  the  following  facts  and
circumstances:

      A. The Loan is to be  evidenced by that  certain  Promissory  Note of even
date herewith (the "Note") in the principal amount of One Hundred Thirty Million
Dollars  ($130,000,000.00)  executed by Borrowers  as an  aggregate  loan to all
Borrowers as hereinafter described.

      B. The Note shall be secured by, among other things,  that certain Deed of
Trust,  Security  Agreement,  and Fixture  Filing with  Assignment  of Rents and
Proceeds of even date herewith  executed by Borrowers,  as Trustor,  in favor of
Prudential, as Beneficiary (the "Deed of Trust").  Capitalized terms used herein
and not  otherwise  defined  shall have the  meanings  given them in the Deed of
Trust.

      C. Borrowers have advised Prudential,  and Prudential has agreed,  subject
to the certifications,  warranties and representations of Borrowers contained in
this Certificate,  that Borrowers desire that the proceeds of the Loan allocated
to each Borrower be allocated  amongst the Borrowers,  but in an amount that (i)
neither  constitutes less than a substantial portion of the fair market value of
the Property of such  Borrower  that is being used as  collateral  for the Loan,
(ii) nor is more than 75% of the value of such  Property  as shown on  Exhibit A
attached  hereto.  Borrowers  understand and  acknowledge  that such  allocation
reflects the  commercial  benefits being received by each Borrower from the Loan
transaction as well as the equitable  allocation of Operating  Partnership Units
held by each Borrower at the time of Loan closing.

      D.  Borrowers  have  requested  that the Loan amount be encompassed in one
loan with a single set of Loan Documents  binding all Borrowers  notwithstanding
that the Loan  proceeds  are to be divided  amongst  Borrowers.  Prudential  has
agreed to allow  Borrowers  to borrow  the funds  using  this  structure  solely
because of Borrowers' request.

      E. On the basis of the foregoing  facts and  circumstances,  Prudential is
willing to make the Loan as requested by Borrowers,  but only in reliance on the
acknowledgments, representations and warranties of Borrowers contained herein.

      NOW,  THEREFORE,  in order to induce  Prudential to make the Loan,  and in
consideration  thereof and with the  understanding  that  Prudential  is relying
thereon, Borrowers hereby jointly and severally agree and certify as follows:

      1. LOAN STRUCTURE.  Borrowers acknowledge that, at Borrowers' request, the
Loan is  made in the  aggregate  to  Borrowers,  and is  evidenced  by and  made
pursuant  to the  Note,  and that the Note is or is to be  secured  by a deed of
trust to be  recorded in Alameda  County,  California  and Santa  Clara  County,
California. The Note provides for joint and several liability among Borrowers at
Borrowers'  request.  Borrowers  further  acknowledge  that  any  nonpayment  of
principal or interest,  including one resulting from one  Borrower's  failure to
pay any portion of the Note or any  installment  of  principal  or interest  due
thereunder,  may result in the Loan being  declared in  default,  and all unpaid
principal  under the Note  accelerated.  Without  limiting the generality of the
foregoing,  in such event all proceeds of the foreclosure sale of any Borrower's
property may be applied to satisfy the Note. Further, each Borrower acknowledges
and understands  that such  foreclosure  sale proceeds may be applied to satisfy
the Note even if the  value of such  Borrower's  property  is  greater  than the
portion of the Note that such  Borrower may be  responsible  for as agreed among
Borrowers. Borrowers have determined the allocation of Loan proceeds pursuant to
standards  set  forth  of the  Recitals  set  forth  in  PARAGRAPH  C above  and
Prudential  shall not be responsible  for the allocation of such proceeds of the
Loan among Borrowers.

      2. CERTAIN CONSEQUENCES OF LOAN STRUCTURE. Each Borrower has been informed
and  understands  that the  consequences  of becoming  obligated  under the Loan
Documents  that  secure  the  Loan  is that  each  Borrower's  respective  land,
improvements and other property is being encumbered as collateral for the entire
Loan. Each Borrower further  understands and has been informed that in the event
of a default  under the Loan,  all  Borrowers  must act together for purposes of
curing  any  defaults,  and  that  the  failure  to do so  could  result  in the
foreclosure and sale, and ultimate loss, of each Borrower's respective Property.

      3. ALLOCATION AND DISTRIBUTION OF THE PROCEEDS OF THE LOAN.

           (a)  Borrowers  hereby  acknowledge,  represent  and warrant that the
      proceeds of the Loan  allocated  to, and to be received by, each  Borrower
      shall be in an amount that (i) neither constitutes less than a substantial
      portion of the fair market value of the Property of such  Borrower that is
      being used as  collateral  for the Loan,  (ii) nor is more than 75% of the
      value of such Property as shown on EXHIBIT A attached  hereto.  The rights
      and  remedies  of  Prudential  under  the  Loan  Documents  shall  not  be
      diminished,  reduced or modified due to  allocation of the proceeds of the
      Loan among Borrowers.

           (b) Each  Borrower  agrees that up to a maximum  amount not to exceed
      its share of the Loan (per subsection (a)(ii)) and corresponding  interest
      and other expenses, it shall reimburse and indemnify and hold harmless the
      other Borrowers (each an  "Indemnitee")  for any claim,  loss,  liability,
      damage or expense suffered or paid by the Indemnitee  (including  payments
      of the Loan  and the loss of the  Indemnitee's  respective  property  as a
      result of the exercise of Prudential's  remedies under the Loan Documents)
      because (i) such Borrower  fails to make its  allocated  share of payments
      under the Loan (based on the  percentages  noted in  subsection  (a) above
      with respect to the Loan),  or (ii) at the time of foreclosure or transfer
      by deed in lieu of foreclosure,  the value of such Borrower's  property so
      foreclosed or transferred has declined  proportionately more (based on the
      percentages  noted in subsection  (a) above with respect to the Loan) than
      another  Indemnitee's   property  since  the  date  of  this  Certificate.
      Borrowers  shall  be  entitled  to set off  claims  related  to this  Loan
      transaction  against one  another so that the  aggregate  obligation  of a
      Borrower  shall not exceed the maximum  amount  provided in the  preceding
      sentence.   Nothing   contained  in  this  Agreement  shall  diminish  the
      obligations  of  each  Borrower  to  indemnify  the  General   Partner  in
      accordance  with  the  terms  of  such  Borrower's   limited   partnership
      agreement.

      4. REPRESENTATIONS  REGARDING LOAN STRUCTURE AND TERMS.  Borrowers jointly
and severally  represent and warrant to Prudential that Borrowers have requested
that the Loan be made upon the following terms and  acknowledge  that Prudential
has agreed to such terms only on account of Borrowers' request to do so:

           (a) The  interest  rate  and  repayment  terms  of the  Loan are more
      favorable than those that each individual  Borrower could have obtained on
      its own without the "pooling" of all of the collateral as security for the
      Loan, and without the joint and several liability features of the Note.

           (b) All of the individual  parcels of land  encumbered by the Deed of
      Trust are  interrelated  in a manner  such that  financing  of each of the
      separate  parcels  apart from the others would be upon terms that are less
      favorable  to  Borrowers,  and  Prudential  would not finance  each parcel
      separately under such more favorable terms.

           (c)  The  structure  of  the  Loan  has  been  devised  in  order  to
      accommodate  Borrowers'  existing  operational  structure in order to best
      serve Borrowers' collective interests.

      5.  REPRESENTATIONS  REGARDING  BORROWERS'  SOLVENCY.   Borrowers  further
jointly and severally covenant, represent and warrant to Prudential as follows:

           (a) The  proceeds of the Loan to be  received  by each of  Borrowers,
      coupled with the additional  consideration  described in subparagraph 4(b)
      and  other  consideration  described  in  the  Loan  Documents  constitute
      reasonably  equivalent value in exchange for all of the transfers made and
      obligations incurred by Borrowers under the Loan Documents.

           (b) The Deed of Trust is not being  executed by  Borrowers  for or on
      account of any antecedent debt owed by any Borrower to Prudential.

           (c) None of Borrowers  is insolvent as of the date hereof,  nor shall
      any  Borrower be  insolvent on the date of the Loan closing or the date of
      any Transfer.

           (d) The execution,  delivery, and recordation of the Deed of Trust is
      intended by Borrowers and Prudential to be a contemporaneous  exchange for
      new  value  given  to  Borrowers,  and  shall  in fact be a  substantially
      contemporaneous exchange.

           (e) The transfers made and  obligations  incurred by Borrowers  under
      the Loan  Documents are not made with actual intent to hinder,  delay,  or
      defraud any entity to which any Borrower was, is, or subsequently  becomes
      indebted.

           (f) No  Borrower  is or  shall  be  insolvent  on the  date  that any
      transfer is to be made or obligation to be incurred under the terms of the
      Loan Documents or on the date of the Loan closing,  nor shall any Borrower
      become insolvent as a result of such transfer or obligation.

           (g) No Borrower is engaged in business or a transaction,  or is about
      to engage in business or a transaction,  on the date of this  Certificate,
      the Loan closing or any such  transfer,  for which any property  remaining
      with such Borrower is an unreasonably small amount of capital.

           (h) No Borrower  intends to incur,  or believes  that it would incur,
      debts that would be beyond  such  Borrower's  ability to pay as such debts
      matured.

      6. INDEMNITY.  Borrowers jointly and severally agree to indemnify, defend,
protect  and hold  harmless  Prudential  against any  losses,  claims,  damages,
liabilities,  or expenses (including  attorneys' fees),  suffered or incurred by
Prudential  in the  event  of any  misrepresentation  by any  Borrower  in  this
Certificate.

      7. ATTORNEYS' FEES.  Borrowers  further agree that if any suit,  action or
proceeding  of any kind (an "action") is brought by any party hereto to enforce,
defend or interpret any provision of this  Certificate  (including an action for
declaratory  relief), the prevailing party in such action shall recover from the
other  parties  to such  action  all  reasonable  costs and  expenses  which the
prevailing party may incur in bringing or defending such action and/or enforcing
any judgment granted therein,  all of which shall be deemed to have accrued upon
the  commencement of such action and shall be paid whether or not such action is
prosecuted  to  judgment.  Any  judgment or order  entered in such action  shall
specifically  provide for the  recovery  of all  reasonable  costs and  expenses
incurred by the  prevailing  party in connection  therewith  including,  without
limitation,  costs and expenses incurred in enforcing such judgment.  Prudential
shall have the right (but not the obligation) to commence,  appear in, or defend
any action  purporting to affect any of the  interests,  rights,  obligations or
liabilities  of Prudential or Borrowers in connection  with this  Certificate or
any document referred to in this Certificate or executed in connection with this
Certificate,  and  Borrowers  agree to pay to Prudential on demand all costs and
expenses reasonably incurred by Prudential in connection therewith.

      8. SURVIVAL.  This Certificate and the representations and warranties made
herein shall survive the closing of the Loan,  and the execution and delivery of
the Loan Documents.

     9.  COUNTERPARTS.   This  Certificate  may  be  executed  in  one  or  more
counterparts and such  counterparts  taken together shall constitute one and the
same document.

      IN WITNESS WHEREOF, Borrowers have executed this Certificate as of the
day and year first written above.

                                    GUARANTY


TO:   The Prudential Insurance Company of America
      Four Embarcadero Center
      Suite 2700
      San Francisco, California  94111

      The undersigned,  ___________________, a _______________ ("Guarantor"), is
a limited  partner in Mission West  Properties  L.P. [ __________  ], a Delaware
limited  partnership (the  "Partnership"),  which is a joint and several obligor
with respect to a  $130,000,000  loan from The Prudential  Insurance  Company of
America, a New Jersey corporation ("Lender"),  pursuant to which the Partnership
on September 22, 1998 has executed and delivered a promissory note (the "Note")
in  the  original  principal  amount  of  One  Hundred  Thirty  Million  Dollars
($130,000,000)  and a Deed of Trust,  Security Agreement and Fixture Filing with
Assignment of Rents and Proceeds (the "Deed of Trust").  The Note is secured and
cross-collateralized   by  certain  properties  of  the  Partnership  and  three
affiliated  limited  partnerships  whose sole  general  partner is Mission  West
Properties,  a  California  corporation,  pursuant  to the  terms of the Deed of
Trust. Loan proceeds of $________________ have been allocated to the Partnership
under the loan terms (the "Partnership  Principal") which are substantially less
than the  value of the  properties  of the  Partnership  secured  by the Deed of
Trust.

      Generally  the terms of the Note and Deed of Trust provide that no partner
in the  Partnership  shall have any personal  liability with respect to the Note
except as  provided  in  Paragraphs  18(b) and (c) of the Note or as provided in
this  Guaranty  when  executed  and  delivered  by a limited  partner to Lender.
Guarantor is providing  this  Guaranty in  connection  with the loan pursuant to
Paragraph 18(b)(i) of the Note.

      1. ACKNOWLEDGMENT.  Guarantor hereby acknowledges that the Partnership has
obtained the  aforementioned  loan from  Lender;  and that the  Partnership  has
executed  and  delivered  the Note and Deed of Trust to  Lender;  and  Guarantor
hereby affirms and approves the same.

      2. AMOUNT OF GUARANTY. Guarantor shall be obligated to pay Lender pursuant
to this Guaranty no more than that amount of the original  principal of the Note
which is provided under this paragraph (the "Guaranteed  Amount")  together with
accrued  and  unpaid  interest  thereon.   The  initial   Guaranteed  Amount  is
____________  _______________________  ($_____________).  The Guaranteed  Amount
shall be reduced simultaneously with each payment by the Partnership of original
principal  under the terms of the Note by an amount  equal to  ________  percent
(__%) of each  such  payment,  which is the same  percentage  as the  Guaranteed
Amount bears to the total original  principal  amount of  Partnership  Principal
that has been guaranteed by limited partners of the  Partnership.  THIS GUARANTY
DOES NOT OBLIGATE THE  GUARANTOR  FOR ANY  EXISTING OR  CONTINGENT  LIABILITY OR
OTHER  OBLIGATION OF THE  PARTNERSHIP  UNDERTAKEN IN CONNECTION WITH THE NOTE OR
DEED OF TRUST EXCEPT FOR THE GUARANTEED AMOUNT.

      3. CONDITIONS TO GUARANTY. Guarantor shall not be liable for any amount to
Lender  pursuant to this Guaranty  unless all of the following  conditions  have
been  satisfied  first:  (a) there exists an event of default under the terms of
the Note or Deed of Trust, (b) Lender has accelerated the payment of the Note in
accordance  with the terms of the Note and Deed of Trust,  (c) Lender has made a
demand on the  Partnership  for payment of all amounts  then due under the Note,
(d) the  Partnership has failed or refused to satisfy all amounts then due under
the Note , (e) Lender has exercised  all of its rights to the  collateral of the
Partnership  securing the Note and has disposed of such collateral in accordance
with the terms of the Note, Deed of Trust and other  agreements  respecting such
collateral,  (f) there remains  unpaid  principal and interest on the Note after
Lender has exhausted its rights with respect to the collateral securing the Note
(including,  but not limited  to,  after  taking into  account the amount of any
indebtedness  owing  under the Note  applied  toward  Lender's  purchase  of any
property  securing  the Note  pursuant  to a judicial  foreclosure,  nonjudicial
foreclosure, or otherwise), (g) the Lender has exhausted all of its remedies and
recourse to all other  assets of the  Partnership,  and (h) Lender has  demanded
payment  from  Guarantor  pursuant to written  notice  specifying  the amount of
principal under the Note then subject to this Guaranty,  which shall in no event
exceed the Guaranteed Amount, and delivered to Guarantor's  address as set forth
in the records of the Partnership.

      4.  Guarantor  hereby waives notice of  acceptance  hereof,  of any action
taken or omitted in reliance  hereon,  and of any defaults of the Partnership in
the payment of any such sums or in the  performance  of any such  covenants  and
agreements.  Guarantor  hereby  agrees that none of the  following  shall in any
manner  release,  affect or impair its liability  under this Guaranty or require
its consent  thereto:  (a) any amendment or  modification of the Note or Deed of
Trust issued thereunder,  including the renewal or extension of any of the Note,
(b) any failure to realize  proceeds from the sale of any property  securing the
Note provided that any such sale is effected in accordance with the terms of the
agreements regarding Lender's security interest in such property.

        family and affiliates  own  approximately  83% of the total  partnership
        interests as limited partners.

o       Approval  of the  acquisition  by Mission  West of the right to acquire,
        through  the  Operating  Partnerships,  certain  commercial  R&D pending
        building developments  consisting of approximately 1.02 million rentable
        square  feet from my family,  affiliates  and me for cash or  additional

o       Approval  of  the  acquisition  of an  option  with  respect  to  future
