                           PROXY STATEMENT/PROSPECTUS

                             MISSION WEST PROPERTIES

                       109,624,072 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  and
existing  cash to fund the  payment of  $35,200,000  owed by the Company for the
acquisition of the sole general  partner  interests  representing  approximately
10.91% of the  total  partnership  interests  in each of four  existing  limited
partnerships   (collectively   the   "Operating   Partnerships")   owning   from
approximately  4.2 to 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") will allow the Company to acquire control of more than 5.2 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 10.91%  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. If the shareholders approve such proposals, all
other transactions will close 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").

     3. Pursuant to AMEX rules, the Company also seeks  shareholder  approval of
the  issuance  of up to  100,825,478  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  Grouppursuant  to the terms of an  Exchange
Rights Agreement among the company,  the Operating  Partnerships and the Limited
Partners (the "Exchange  Rights  Agreement") to take effect at the final closing
date for the Berg Acquisition.

     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
    

<PAGE>

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" also may refer to Mission
West-Maryland  unless the discussion concerns the Reincorporation  Merger or the
Charter or the Mission West-Maryland bylaws.

     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 and the purchasers of shares in the Private Placement of
(i)  8,193,594  shares of  Common  Stock  (after  giving  effect to the  Private
Placement) 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  100,825,478  shares of New Common
Stock for  issuance  upon any future  exchange of L.P.  Units as a result of the
Reincorporation Merger.

     The  Company  has  filed  a   Registration   Statement  on  Form  S-4  (the
"Registration  Statement") with the Securities and Exchange  Commission pursuant
to the  Securities Act of 1933, as amended (the  "Securities  Act") covering the
shares of New Common Stock to be issued in 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

   
     The Berg Acquisition concerns 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  4.2
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," intended to be effective as of July 1, 1998, as well
as rights to acquire  additional  R&D  Properties,  as  described  below,  after
shareholder  approval.  On July __,  1998,  the  Company  and the parties to the
Acquisition  Agreement  agreed to consummate  the Company's  acquisition  of the
general partner interests in the Operating Partnerships, effective for financial
and  income  tax  accounting  and  reporting  purposes  as of July 1,  1998 (the
"Partnership Closing"), in advance of the Special Meeting, 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 each of the  Operating  Partnerships  a demand  note  7.25%  interest  with a
principal  amount  equal to  10.91%  of the net  asset  value  of the  Operating
Partnership,  as provided in the Acquisition Agreement as amended by the parties
effective  as of July 1,  1998.  Each note is  payable  upon the  closing of the
Private  Placement,  or an equivalent  transaction,  or, if earlier,  on July 1,
2000.

     As a consequence of the Partnership  Closing,  the Company now controls the
Operating  Partnerships,  all of 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.

     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 in connection
with the Berg Acquisition.  By amendment to the 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")  subject to a purchase  option
held by Mr.  Berg.  A  dispute  has  arisen.  Based  upon  the  parties  current
positions,  the Company believes that this dispute will result in litigation The
Acquisition  Agreement,  as  amended,  obligates  Mr. Berg to convey the Fremont
Properties  to MWP,  if and  when he  completes  his own  acquisition  of  those
Properties.  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 Properties  rentable  square footage owned and operated by
the Operating  Partnerships  following  the  Partnerships'  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 certain R&D Properties (the "Kontrabeki Properties") held by the three
limited partnerships (the "Kontrabecki  Partnerships")  previously controlled by
John Kontrabecki and the Fremont Properties.

     Under the terms of the Acquisition  Agreement,  the Operating  Partnerships
and the Company also have agreed to the terms of 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 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
Placement,  5,800,000  shares were  offered in a placement  managed by Ingalls &
Snyder LLC ("Ingalls & Snyder"). The

                                       -3-
<PAGE>

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  75,100,000.  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
Related L.P. Unit Allocation 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 March 31 1998, the Berg Properties were 100% occupied,  with a total of 73
tenants  principally  engaged in the information  technology  business,  and the
Acquired  Properties  were  100%  occupied  by a total of 10  tenants.  The Berg
Properties  currently are subject to total  indebtedness of  approximately  $78_
million,  of which  approximately  $38.2  million is  secured by first  deeds of
trust. Certain of the Acquired Properties are subject to secured indebtedness of
approximately $39.2 million. At the final closing for the Berg Acquisition,  the
Company  intends to obtain  $130  million of new  secured  debt  financing  from
Prudential  (the "New  Secured  Loan") and a $50  million  line of  credit.  The
proceeds  of the New  Secured  Loan along  with the  proceeds  of the  Company's
purchase of its  interest in the  Operating  Partnerships  will be used to repay
$82.6 million of existing debt secured by the Berg  Properties  and the Acquired
Properties,  incurred prior to the Partnership Closing to fund a distribution of
approximately $91.6 million to members of the Berg Group. See "BACKGROUND OF THE
UPREIT  TRANSACTIONS--Consequences  of the  Berg  Acquisition  and  the  Private
Placement" and "DESCRIPTION OF THE PROPERTIES."

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.
During 1998, the Company expects to pay quarterly distributions of approximately
$0.085 per share of Common Stock. 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 operations 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 does expect 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  84.6% 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 Berg Land
Holdings 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
("Independent  Directors  Committee") 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."
    

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 will be accounted for as a recapitalization of the
Berg Properties in a manner similar to reverse acquisition  accounting recording
the  historical  carrying  value of assets with the  exception  of the  Acquired
Properties.  The Acquired Properties will be accounted for as a purchase for the
Fremont  Properties and as a  step-acquisition  for the Kontrabecki  Properties.
Pursuant  to the  step-acquisition  for the  Kontrabecki  Properties,  The  Berg
Group's ownership interest will be recorded at their historical  carrying value.
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 held 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.  The Company
intends to file with the  Commission  a  registration  statement  on Form S-8 to
register  shares of Common  Stock  reserved  for  issuance  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)
     66,906,406  L.P.  Units  that are  exchangeable  for  common  shares of the
     Company's  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  industry
     analysts  have  accepted  it as such.  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. 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  industry
     analysts  have  accepted  it as such.  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. 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 "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.  As a result of the Berg  Acquisition,  Carl E. Berg and
other Berg Group Members will relinquish  control of the Berg Properties,  which
have a total book value of $98,453 as of March 31,  1998,  to the  Company,  and
debt owed to or  guaranteed  by Mr.  Berg and other  members  of the Berg  Group
totaling  approximately $143 million will be repaid with the proceeds of the New
Secured Loan and the Company's purchase of the general partnership  interests in
the Operating Partnerships, including $77 million for debt incurred by MWP I and
MWP II prior to the Partnership Closing to fund a distribution to members of the
Berg Group.  The valuation of the Company  implied by the Company's  purchase of
the 10.91% 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."
    

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 substantial
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.  See  "POTENTIAL  CONFLICTS OF  INTEREST."  In  particular,  Mr. Berg is a
substantial  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 of 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 84.4%
limited partnership interest in the Operating Partnerships,  and an aggregate of
84.6% of the  Outstanding  Shares,  (without  regard to the Berg Group Ownership
Limit) through 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-

     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.  In addition,  unless Mr.
Berg can resolve the dispute which has arisen concerning the Fremont  Properties
in a manner which allows him to acquire those  Properties,  he will be unable to
contribute them to an Operating Partnership.

     PENDING DEVELOPMENT  PROJECTS.  There are four Pending Development Projects
which  represent  a total of 12 R&D  Properties  and  approximately  one million
rentable  square feet in the aggregate.  Under the  Acquisition  Agreement,  the
Company and the owners of these  Properties  have agreed that the Company or the
Operating  Partnerships  will  acquire  each  of  the  R&D  Properties  as it is
completed  and  leased.  Under the  terms of the  Pending  Projects  Acquisition
Agreement the sellers of the  Properties may elect to receive cash or L.P. Units
at a value of $4.50 per unit. The purchase price for each of the Properties 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 of the  Properties  prior to their  transfer to the
Company.  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 or 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.

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 March  31,  1998,  after  giving  effect to the Berg  Acquisition,  26 of the
Properties are mortgaged to secure  payment of debt, and the Company  expects to
have outstanding approximately $164.6 million of debt secured by such Properties
for the  final  closing  date for the Berg  Acquisition,  following  shareholder
approval at the Special Meeting.  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 Lines" 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  32.8% at March 31, 1998,
assuming  the  occurrence  of the UPREIT  Transactions,  a Market Price of $4.50
price per share, and 75,100,000 Outstanding Shares issued and
    

                                           -13-
<PAGE>

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.

     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 has 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.

                                      -15-

<PAGE>

   
     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.

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."
    

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 year  following  the Berg  Acquisition.  During such initial  12-month
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

                                    -17-
<PAGE>

"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  which  would  be  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. Sales of shares acquired by members of the Berg Group and other
Limited  Partners through the exercise of their Exchange Rights and registration
rights may  adversely  impact the price and trading  volume of the Common  Stock
from time to time to the detriment of other shareholders.

                               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 most of the interests in the limited  partnerships  comprising the
Operating  Partnerships  and, upon final  consummation of the Berg  Acquisition,
including   acquisition  of  the  Fremont  Properties,   will  beneficially  own
63,381,987 L.P. Units, or approximately 84.4% of the Operating Partnerships. The
remaining  3,524,421 L.P. Units will be 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. Certain of the Acquired
Properties  known as the "Fremont  Properties"  are subject to an option held by
Carl E. Berg. Mr. Berg intends to acquire and contribute the Fremont  Properties
to the  Operating  Partnerships  at or  before  the final  closing  for the Berg
Acquisition, although he first must resolve a dispute, which is unrelated to the
activities of the Company or the Operating Partnerships, with the current owners
of the Fremont  Properties.  The Company  believes that this dispute may lead to
litigation  and there can be no assurance  that Mr. Berg will be able to reach a
resolution of the dispute and acquire the Fremont  Properties prior to the final
closing  date  for the  Berg  Acquisition.  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 March 31, 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.

     Two  substantially  similar  Voting Rights  Agreements  (the "Voting Rights
Agreements")  cover all shares of Common  Stock  acquired  from the Company in a
private  placement in September 1997, as well as a substantial  number of shares
acquired from the Company in a private placement in November 1997. Consequently,
the holders of the 1,097,959 shares subject to the Voting Rights Agreements have
agreed to vote their shares of Common  Stock as directed by Mr. Berg,  on behalf
of BBE, on all matters  submitted to a vote of the  shareholders of the Company.
The Voting Rights  Agreements  terminate at the earliest of the following dates:
(i) upon any sale of the shares  pursuant to a registration  statement  declared
effective under the Securities Act of 1933, as amended (the  "Securities  Act"),
but only as to the shares so sold;  (ii) upon a sale of the shares  pursuant  to
Rule 144  promulgated  under the  Securities  Act,  but only as to the shares so
sold; (iii) two years after the effective date of the Voting Rights Agreement.

     BBE has advised the Company  that it will not exercise its rights under the
Voting  Rights  Agreements  with  respect to any of the  Proposals  to allow for
approval of the Proposals by the holders of a majority of shares of Common Stock
without regard to any voting rights possessed  directly or indirectly by members
of the Berg Group. Accordingly,  all holders of Common Stock will be entitled to
determine  independently  whether to vote  their  shares in favor of each of the
Proposals.  Furthermore,  BBE has advised the Company that it will terminate the
Voting Rights  Agreements  following the approval or  ratification of all of the
UPREIT Transactions at the Special Meeting.
    

CONSEQUENCES IF THE PROPOSALS ARE NOT APPROVED

   
     The board of directors adopted resolutions  approving Proposals 1 through 6
on May 14, 1998, subject to shareholder approval or ratification.  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.  As the Company
and other parties to the Acquisition Agreement completed the Partnership Closing
on 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 L.P.  Unit Majority may call the demand notes issued at
the Partnership  Closing,  which currently total approximately $33.6 million and
which the Company will need to finance by that date at the latest.  Accordingly,
if the shareholders do not approve the Private Placement,  the Company will seek
to obtain the amount of funds to be  provided by the  Private  Placement  in the
same or another manner. 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,  which the
Company  believes would  materially  diminish the Company's  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 and could ask
BBE, which is also a party to the Acquisition Agreement to advise the holders of
the shares subject to the Voting Rights Agreements to vote their shares in favor
of the proposal at the new meeting.

     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.


                                    -20-
<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
INCOME  TAX  CONSIDERATIONS  --  Taxation  of the  Company --  Requirements  for
Qualification."
    

DISSENTERS' RIGHTS

     Under  California  law,  none of the  shareholders  of the Company  will be
entitled to exercise  dissenters'  rights with respect to any of the  Proposals.
See "THE REINCORPORATION MERGER--Approval and Effectiveness of Merger."

RECOMMENDATION OF THE BOARD OF DIRECTORS

     The board of directors of the Company  unanimously  recommends  votes "FOR"
Proposals 1 through 6.

                      BACKGROUND OF THE UPREIT TRANSACTIONS
    

INTRODUCTION

   
     Following the sale of all of its  properties in the first half of 1997, the
Company's announced objective has been to re-enter the real estate business.  In
May 1997, BBE and the Company  entered 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,  as  disclosed  in  the  Company's  July  8,  1997  Proxy
Statement, that the Company would achieve that objective by acquiring 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  and  making
arrangements to acquire  additional R&D Properties.  Those efforts culminated in
the  execution  of the  Acquisition  Agreement  in May 1998.  In July 1998,  the
Acquisition Agreement was amended and the Company acquired an approximate 10.91%
interest as the sole general partner in each of the Operating Partnerships.  The
Operating  Partnerships  now own all of the Berg  Properties and the Kontrabecki
Properties,  and will acquire the Fremont Properties once Mr. Berg has purchased
them, resulting in a total of approximately 4.34 million rentable square feet of
R&D  Properties  to be held in the  Operating  Partnerships.  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  the  L.P.  Units  issuable  to  Mr.  Berg  for  the  Fremont
Properties,  the Berg Group will own L.P. Units representing approximately 84.4%
of the interests in the Operating Partnerships,  and non-Berg Group parties will
own approximately 4.69% of the interests in the Operating Partnerships, prior to
the acquisition of any Pending Development Projects.

     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.

     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  (collectively the
"Berg Voting Group") signed the Voting Rights  Agreements.  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 Berg Voting Group acquired a 79.6% controlling ownership position in the
Company.


     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  from  members  of the Berg  Voting  Group for the
purchase of their shares. No portion of the distribution was paid on shares held
by the members of the Berg Voting Group. In connection  with that  distribution,
the AMEX halted trading of the Common Stock at the opening of trading on October
20, 1997.
    
                                    -22-

     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. In November  1997, the Company  changed its
fiscal year to December 31.

     THE OPERATING PARTNERSHIPS.  On July __, 1998, the Company acquired control
of the four  Operating  Partnerships  by becoming the sole  general  partner and
acquiring an approximate  10.91% interest in each one, which became effective as
of July 1, 1998 for financial and partnership income tax accounting purposes. To
purchase its  interest the Company  issued  Demand Notes of  approximately  $6.9
million, $6.7 million, $19 million, and $1 million to MWP, MWP I, MWP II and MWP
III,  respectively.  Although  each  Demand  Note is payable on demand,  no such
demand may be made prior to the earlier of the closing of the Private  Placement
or July 1, 2000.  Demand under each note may be made by action of the holders of
a majority of the  outstanding  L.P. Units in the  partnership.  Interest on the
Demand  Notes is  computed  at the rate of 7.25,  compounded  semiannually.  The
amendment to the Acquisition Agreement,  dated as of July 1, 1998, provides that
upon the  acquisition  of the Fremont  Properties  by MWP,  the Company  will be
required to pay MWP an additional  $1.6 million to maintain its 10.91%  interest
in that partnership.

     As a consequence of the  Partnership  Closing,  the Operating  Partnerships
currently hold R&D Properties with an aggregate book value as of March 31, 1998,
of $135.2 million (net of accumulated depreciation of $82.6 million), subject to
total debt of $158.7 million.  The Fremont Properties will have a total purchase
price of $19.7 million which include  indebtedness of $5.9 million when acquired
by the Operating  Partnerships.  Upon the completion of the Berg Acquisition and
the  implementation  of the New Secured Loan, the total amount of collateralized
indebtedness of the Operating Partnerships will be $164.6 million, none of which
will be owed to related parties.

     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 a
Wells Fargo Bank N.A.  ("Wells  Fargo") line of credit,  in the event of payment
default by the Operating Partnerships. The Limited Partners have assumed a share
of this debt to preserve  basis for federal  income tax purposes,  and intend to
provide limited  guaranties of a similar nature to Prudential upon the refinance
of the Wells Fargo debt with the New Secured Loan, and other proceeds.

     As a result of the Partnership Closing, the Operating Partnerships now have
an aggregate of 63,844,980  L.P. Units  outstanding,  of which  60,320,520  L.P.
Units are held by Carl E. Berg and other  members of the Berg  Group.  Mr.  Berg
will receive  3,061,427  additional  L.P.  Units from upon his  acquisition  and
contribution of the Fremont Properties to MWP.

     All of  the  Operating  Partnerships  are  governed  by  the  terms  of the
Operating Partnership Agreement and the Acquisition Agreement,  as amended. Upon
the final closing date for the Berg Acquisition, the Operating Partnerships also
will be subject  to the terms of the  Exchange  Rights  Agreement,  the  Pending
Projects Acquisition Agreement and the Option Agreement.

     The Operating  Partnerships  are  maintained as separate  entities to avoid
unnecessary  transfers  of real estate  interests  and  maintain  favorable  tax
depreciation  methods and periods.  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  proportionately with 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 share of
all  distributions  with  respect to its  interest  in each of the four  limited
partnerships will be identical.  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."
    

     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  at the same  time as 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.

     ADDITIONAL  DEBT  ARRANGEMENTS.  After the final  closing date for the Berg
Acquisition,  the Company and the  Operating  Partnerships  expect to obtain the
$130 million New Secured Loan to be secured by 14 of the Properties.  All of the
proceeds  of the New  Secured  Loan  will be used to  refinance  existing  debt,
including  approximately  $33 million of debt outstanding  under lines of credit
guaranteed  by all of the  Berg  Group  members.  At  the  closing  of the  Berg
Acquisition,  the Company and the Operating Partnerships also intend to obtain a
$50 million revolving line of credit, which they are currently  negotiating with
several financial  institutions  (the "New Credit Line").  Proceeds from the New
Credit Line will be used for working  capital.  Certain of the Limited  Partners
may guaranty all or part of the outstanding  debt under the New Secured Loan for
federal  income  tax  considerations.  See  "DESCRIPTION  OF THE  PROPERTIES  --
Mortgage Debt and Credit Line" and "FUTURE  OPERATIONS OF THE COMPANY -- Line of
Credit -- Mortgage Indebtedness Outstanding After Berg Acquisition."
    

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.   In  connection  with  the  Company's  July  1997  solicitation  of
shareholder approval for the sale of shares of Common Stock constituting control
of the Company to BBE and its co-investors,  the Company expressed its intention
and desire to continue its historical  involvement  in the real estate  business
through  some form of  business  combination  with the Berg  Group.  The Company
believes  that the UPREIT  Transactions  fulfill  that  objective.  See  "FUTURE
OPERATIONS OF THE COMPANY--Operating and Growth Strategy."

     Moreover,  the  acquisition  of a  controlling  interest  in the  Operating
Partnerships  rather than the direct  acquisition of any of the Properties  will
enhance 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 can 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 will
simplify the  accounting  procedures  associated  with  recording the associated
transactions,  permit clearer financial statement presentation,  reduce the risk
that  the  Company  might  fail to meet  the 75%  gross  income  test  for  REIT
qualification  in 1998,  and help the  Company  to avoid  regulation  under  the
Investment Company Act of 1940.

     After the final  closing  of the Berg  Acquisition  and the  closing of the
Private Placement,  the Company will have 75,100,000 Outstanding Shares, and the
Berg  Group  will  have  beneficial  ownership  of  approximately  84.6%  of the
Outstanding Shares (assuming contribution of the Fremont Properties). Except for
the Excluded Properties,  the Properties in the Company's initial portfolio will
include all of the Silicon Valley R&D Properties  currently  owned by any of the
Berg Group members
    

SUMMARY OF THE TRANSACTIONS

   
     The  Berg  Acquisition  and  Private  Placement  transactions  include  the
following events (assuming acquisition of the Fremont Properties):
    

- -    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 and become  Limited
     Partners.

- -    The  Company  has  become  the  sole  general   partner  of  the  Operating
     Partnerships by acquiring an approximate 10.91% interest in the capital and
     profits of the Operating  Partnerships  for $35.2 million ($33.6 million of
     Demand  Notes  payable  upon  closing of the  Private  Placement,  and $1.6
     million payable upon contribution of the Fremont Properties to MWP).

- -    Existing  Limited  Partnership  interests  will  have been  converted  into
     52,695,177  L.P. Units and a total of 14,211,229  L.P. Units will have been
     issued in exchange for R&D  Properties  contributed to MWP by Carl E. Berg,
     certain Berg Group members, and two of the Kontrabecki Partnerships.
    

                                    -24-
<PAGE>

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

   
- -    The Operating  Partnerships will give certain Limited Partners 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
     Berg Land Holdings 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 will transfer its property  management  business to the Company
     and will lease a portion of its Bandley Drive  headquarters  to the Company
     pursuant to the Office Lease.

   
- -    The  Operating  Partnerships  will obtain  secured  debt of $130 million to
     repay $33.3 million of existing debt secured by the Kontrabecki  Properties
     and $49.3 million of existing debt secured by some of the Berg  Properties.
     Existing debt secured by some of the Berg Properties and Fremont Properties
     totaling approximately $34.6 million will remain outstanding.

- -    For income tax reasons  certain  Limited  Partners  have assumed  secondary
     personal liability of existing debt and the same Limited Partners intend to
     guaranty  payment  of all or some  portion  of the New  Secured  Loan.  The
     existing  liability  assumption  and  allocation  agreements  and  the  new
     guarantees  would 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 its assets.
    

CONSEQUENCES OF THE BERG ACQUISITION AND THE PRIVATE PLACEMENT

   
     The  Berg  Acquisition  and  the  Private  Placement  will  result  in  the
following:
    

- -    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 will be the sole general  partner of, and own a 10.91% interest
     in, the Operating Partnerships.

- -    The members of the Berg Group will  beneficially  own 63,381,987 L.P. Units
     representing  in the aggregate an  approximate  84.4%  limited  partnership
     interest in the Operating Partnerships.

- -    Individuals  and  entities,  other  than  members of the Berg  Group,  will
     directly and  indirectly  own  3,524,421  L.P.  Units  representing  in the
     aggregate  an  approximate  4.69%  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 New  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  will have been
used to repay $82.6 million of existing debt secured by the  Properties,  and to
make a distribution of approximately  $91.6 million to Carl E. Berg and Clyde J.
Berg prior to the Partnership Closing.
    

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 (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.

     - Certain debt relating to the  Properties  will be  refinanced,  including
debt of  approximately  $33 million owed under lines of credit for which members
of the Berg Group are personally  liable.  However,  in connection  with the New
Secured  Loan,  members  of the Berg  Group and other  Limited  Partners  in the
Operating  Partnerships may provide  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  will
succeed 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  10.91% general partner interest
in the Operating  Partnerships  for $35.2 million,  which  (assuming  75,100,000
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 upon the resumption of trading of the Common Stock on the AMEX, it is
likely that the Common Stock will trade at a different price.
    

                                    -26-
<PAGE>

   
         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 March
31, 1998. 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)  Per  share  calculations  do  not  consider  the  dilutive  effect  of  (i)
     66,906,406  L.P.  Units  that are  exchangeable  for  common  shares of the
     Company's  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  industry
     analysts  have  accepted  it as such.  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. 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

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 close to 100% 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.

     As a result,  the Company  believes  that average  asking rental rates will
continue to increase during 1998 and 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

                                       -33-

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.

     During 1998 and 1999,  13 Berg  Properties  representing  521,000  rentable
square feet will be available for new leases or rent renewals.  These Properties
are located in Milpitas,  Cupertino,  Sunnyvale and San Jose,  which the Company
believes are in the highest  rent  category in Silicon  Valley,  aside from Palo
Alto, a very  specialized  market with a low base of R&D Property square footage
and an  occupancy  rate of 99.4%  according to BT  Commercial.  Based on current
conditions in the Silicon Valley R&D  Properties  market,  the Company  believes
that it will be able to lease these  Properties at rents which exceed the rental
rates under the existing leases.

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-
<PAGE>

               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  industry
     analysts  have  accepted  it as such.  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. 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.

   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
                          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
operations,  assets  and  liabilities  of the  Berg  Properties  other  than the
Acquired  Properties and the Pending Development  Projects.  As part of the Berg
Acquisition,  the Kontrabecki Properties became part of the real estate holdings
of the  Operating  Partnerships  at the  Partnership  Closing,  and the  Fremont
Properties  will be  contributed  when,  and if,  acquired by Carl E. Berg.  The
Company is the sole general partner and the beneficial owner of an approximately
10.91% interest in the Operating Partnerships, and, in general, will control the
operations  and  activities  of the  Partnership.  As a result,  for  accounting
purposes,  the  financial  information  of the  Operating  Partnerships  and the
Company will be consolidated, as of 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 March 31, 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, 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 that have owned the Berg Properties
and 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
will be terminated upon the closing of the Berg Acquisition.

     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.

     RENTAL REVENUES AND TENANT REIMBURSEMENTS. Rental revenue increased by $2.3
million,  or 26.1%,  to $11.1  million for the three months ended March 31, 1998
compared  to $8.8  million  for the  three  months  ended  March 31,  1997.  The
principal  reasons for the  increase in rental  revenue were the increase in the
overall occupancy rate for the Berg Properties,  from 96.2% at March 31, 1997 to
100% at March 31, 1998, the addition of  approximately  296,000  rentable square
feet of leased  space  during the second and third  quarters of 1997,  scheduled
rental rate increases,  and the higher rents associated with new leases.  Tenant
reimbursements  increased  by $0.8  million,  or 66.7%,  to $2.0 million for the
three  months  ended March 31, 1998 from $1.2 million for the three months ended
March 31, 1997. The increase in tenant  reimbursements  was due primarily to the
higher  occupancy  level,  the increase in total rentable  square feet of leased
space, and an increase in the number of tenants  reimbursing the Berg Properties
for operating expenses instead of paying them directly to the service provider.

     EXPENSES. Total expenses for the Berg Properties increased by approximately
$0.4  million,  or 7.1%,  to $6.0  million for the three  months ended March 31,
1998,  compared to $5.6  million  for the three  months  ended  March 31,  1997.
Property operating expenses decreased slightly by approximately $0.1 million, or
approximately  9.1%,  to  approximately  $1.0 million for the three months ended
March 31, 1998 compared to approximately $1.1 million for the three months ended
March 31, 1997. Depreciation expense increased by approximately $0.2

                                     -39-

million,  or 11.8%,  to $1.9  million for the three  months ended March 31, 1998
compared to $1.7 million for the three months ended March 31, 1997  primarily as
a result of new improvements and new  construction.  Real estate taxes increased
slightly  and  interest  expense  (including  amounts  associated  with  related
parties) for the three months ended March 31, 1998 was essentially  unchanged in
comparison to the quarter ended March 31, 1997, as debt  principal  balances and
interest rates remained substantially the same.

     NET INCOME.  Net income increased by  approximately  $2.6 million to almost
$7.1 million for the three  months  ended March 31, 1998,  an increase of nearly
58% over the net income of $4.5  million for the  comparable  period ended March
31, 1997. The substantial  rise in net income resulted from a combination of new
leases at higher rental rates and scheduled  rental rate  increases,  as well as
the addition of leased space, while operating expenses and interest expense were
flat and real estate taxes,  depreciation and amortization  expense, and the BBE
management fee resulted in an overall increase in expenses for the first quarter
of 1998 of just $0.4 million or,  approximately  7.1%, over the first quarter of
1997.

         THE ACQUIRED PROPERTIES

     RENTAL  REVENUES AND TENANT  REIMBURSEMENTS.  Rental  revenue for the three
months ended March 31, 1998 was $1.7 million for the Acquired  Properties,  with
$1.2 million coming from the Kontrabecki Properties and $0.5 million coming from
the Fremont Properties.  Tenant  reimbursements and other income were a combined
$0.06 million,  mostly attributable to the Fremont  Properties.  The Kontrabecki
Properties had minimal expenses and minimal tenant reimbursements as the tenants
paid most of their expenses directly to the service providers.

     EXPENSES.  Total expenses for the Acquired  Properties  were $0.03 million,
all of which were attributable to the Fremont Properties.

     REVENUE IN EXCESS OF CERTAIN  EXPENSES.  The combined  revenue in excess of
certain  expenses of the Acquired  Properties  was $1.7  million,  of which $1.2
million was derived from the  Kontrabecki  Properties  and $0.5 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.

     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 first quarter of 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."

   
     Upon completion of the Berg Acquisition,  the Company expects to have total
indebtedness on the Properties of  approximately  $164.6  million,  comprised of
mortgage  debt secured by certain of the  Properties  under the New Secured Loan
and existing secured loan  arrangements for $34.6 million.  The New Secured Loan
financing is expected to total $130 million,  bearing an interest rate of 6.56%,
with a term of 10  years,  payable  in  monthly  installments  of  interest  and
principal (based upon a 30 year amortization) of approximately $0.8 million. The
Company  will be required  to pay total fees of  approximately  $0.5  million in
connection  with  this  new  secured  loan  which is  expected  to close in late
September 1998. The Company also expects to have $50 million available to borrow
under the New Line of Credit. The Company's debt to Total Market  Capitalization
ratio will be approximately 32.8% based upon an estimated market  capitalization
of approximately $503 million.
    

     The Company expects to meet its short-term liquidity requirements generally
through its initial working capital,  the New Credit 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  that
substantially  all of these sums will be recouped  from the tenants under new or
renewed leases by way of increased 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 (including the New Credit Line) 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  $9.8 million and $5.5
million for the three  months ended March 31, 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 $4.3 million increase in net
cash provided by operating  activities for the three months ended March 31, 1998
compared  to the same  period in 1997 was  primarily  due to an  increase in net
income,  a reduction in the increase in other assets,  as well as an increase in
accounts payable and accrued expenses.  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 used in investing activities with respect to
the Berg  Properties  was  approximately  $0.2  million and $3.5 million for the
three  months  ended March 31, 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 $3.3 million decrease in net cash used
in investing  activities  for the three months ended March 31, 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 $(0.5)  million and $(0.6)  million for the
three months ended March 31, 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  have been
directly  related  to the  level  of new  construction  and  development  of R&D
Properties by the Berg Group. Comparing the three months ended March 31, 1998 to
the three months ended March 31, 1997,  there were no changes in debt other than
normal recurring  principal  payments,  and capital  distributions  decreased to
$0.01  million for the three  months  ended March 31, 1998 from $0.4 million for
the three months ended March 31, 1997. 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, the Berg Group  increased  total debt on the Berg
Properties by $4.0 million, increased capital contributions by $9.3 million, and
reduced capital distributions 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 $3.3  million for the three  months ended March 31,
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.

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,  currently  are, or prior to the
final  closing  of  the  Berg  Acquisition  will  be,  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.

AVERAGE OCCUPANCY AND RENTAL RATES

     The  following  table sets forth the  aggregate  average  percent of square
footage  leased and the average  Annual Base Rent per leased square foot for the
Berg Properties for the periods specified:

     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. Upon completion of the Berg
Acquisition,  the Apple  Properties  will 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

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

<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"). Upon completion of the
Berg Acquisition,  the Amdahl Properties will 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.  Upon  completion  of the Berg  Acquisition,  the  Cisco  Properties  will
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 would comprise
approximately  21.63%  of the  Operating  Partnerships'  total  rentable  square
footage  following the Berg  Acquisition.  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."

STANDARD BERG & BERG LEASE TERMS

     The standard lease agreement used by Berg & Berg is a triple net lease. The
term of the  standard  lease  ranges  from  three to ten years with one to three
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.

AVERAGE OCCUPANCY AND RENTAL RATES

     The  following  table sets forth the  aggregate  average  percent of square
footage  leased and the average  Annual Base Rent per leased square foot for the
Acquired Properties for the periods specified:

     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  Project  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.

LAND HOLDING AND DEVELOPMENT ARRANGEMENTS

   
     BERG LAND HOLDINGS.  Certain  members of the Berg Group,  including Carl E.
Berg, own several parcels of undeveloped  real estate in the Silicon Valley (the
"Berg Land  Holdings")  which have been made available to the Company for future
development,  subject to closing  the Berg  Acquisition,  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  at a price  equal to (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 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

          -    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

               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 sell such building to a third party.

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

(3)  One month LIBOR plus 1.625% adjusted monthly.

(4)  The Company is currently in negotiations with Prudential Capital to procure
     the  New  Secured  Loan  expected  to  total  $130  million.   The  Company
     anticipates that the New Secured Loan will have an initial term of 10 years
     with an interest  rate of 6.56%.  At this time,  there can be no  assurance
     that the  Company  will be able to  complete  this  transaction  or another
     transaction  with similar terms.  Management  believes that if negotiations
     were commenced with a new potential  lender,  the interest rate  negotiated
     would  approximate 7% (the current  prevailing market rate), and therefore,
     the Company has assumed an interest rate of 7% for this loan.

     CREDIT LINE. 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.  At the closing of the Berg  Acquisition,
the Company intends to repay indebtedness of approximately $33 million under the
Wells Fargo lines of credit  which are  secured by some of the  Properties.  The
Company also intends to repay

                                     -59-
<PAGE>


approximately  $33.3 million of indebtedness under the Wells Fargo line which is
secured by some of the Acquired  Properties.  The Company  intends to obtain the
New Credit Line the final  closing  date for the Berg  Acquisition.  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  limited  partnerships
comprising the Operating  Partnerships,  only Mission West Properties,  L.P. has
had any Properties transferred to it as part of the Berg Acquisition;  the other
three limited partnerships will retain their historical Properties. The Property
transfers to Mission West  Properties,  L.P.  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. Upon completion of
the Berg Acquisition,  the Company, through its general partnership interests in
the  Operating  Partnerships,  will  own  and  operate  69  Silicon  Valley  R&D
Properties.  As of March 31, 1998,  the  occupancy  rate of the  Properties  was
approximately  100%.  The Company  also will  acquire the 12 Silicon  Valley R&D
Properties  comprising the Pending  Development  Projects,  and has an 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 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.  Frequently,  the IPO
proceeds are used to fund the companies' growth and expansion,  with a resulting
need for additional  space.  The Company believes that this financial 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.

     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  constructed by the
Berg Group on the Berg Land Holdings under the Option Agreement.  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.

LINE OF CREDIT

     The  Company  intends  to obtain  the New  Credit  Line in order to finance
acquisitions  and for  general  corporate  purposes.  It is  expected  that  the
available credit facility will be approximately $50,000,000.  Management expects
to obtain this line of credit from a national or regional  lending  institution.
The  Company  intends to have the line of credit in place by the  closing of the
Berg Acquisition.

MORTGAGE INDEBTEDNESS OUTSTANDING AFTER BERG ACQUISITION

   
     The Company  intends to obtain  mortgage  financing  in order to  refinance
existing  indebtedness.  Management  has had  discussions  with  three  national
lending institutions  regarding the mortgage financing.  It is expected that the
financing  will be secured by a group of the  Properties.  This New Secured Loan
financing is expected to total $130 million, with a term of 10 years,  amortized
over 30 years,  resulting in monthly debt service  obligations  of $0.8 million.
The  Operating   Partnerships  expect  to  pay  approximately  $0.5  million  as
application  and financing  fees for the New Secured Loan. In addition,  secured
loans totaling  approximately  $34.6  million,  which are secured by some of the
Properties,  will remain  outstanding  following  the  consummation  of the Berg
Acquisition.  See "MANAGEMENT'S  DISCUSSION AND ANALYSIS OF FINANCIAL  CONDITION
AND RESULTS OF OPERATIONS FOR THE PROPERTIES -- Pro Forma  Liquidity and Capital
Resources."

                               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  88% 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 pro forma FFO of the Company for all
of the Properties for the twelve months ending March 31, 1999, with  adjustments
for certain known events  occurring  after March 31, 1998 that are not reflected
in the Company's historical or pro forma financial statements.
    

DISTRIBUTION TABLE

     The following table  illustrates the adjustments  made to the Company's pro
forma FFO for the twelve months ended March 31, 1998, as adjusted, in estimating
its initial dividend:

</TABLE>
    
- ------------------
(1)  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.

   
(2)  Represents the net increases in contractual rental income, net of expenses,
     from new leases and renewals  that were not in effect for the entire twelve
     month  period  ended March 31, 1998 and new leases and  renewals  that went
     into effect between March 31, 1998 and July 8, 1998.  Rental Income has not
     been  included  for  any   properties   for  the  periods  prior  to  their
     construction completion and availability for occupancy.
    

(3)  Effect of  adjusting  straight-line  rental  income  included  in pro forma
     adjusted FFO for the twelve months ended March 31, 1998 to a cash basis.

(4)  Represents scheduled payments of debt principal due during the 12 months
     ending March 31, 1999.

                                     -64-

(5)  Anticipated  leasing  commissions  to be incurred  based on the  historical
     weighted average of such commissions paid in connection with lease renewals
     and  re-leasing at the  Properties  multiplied by the average annual square
     feet of space for which leases  expire during the period from April 1, 1998
     through December 31, 2000.

(6)  The  estimated  cost  of  recurring  building  improvements  and  equipment
     replacements  (excluding  tenant  improvements)  at the  Properties for the
     twelve months ending March 31, 1999.  Generally,  the  Properties and their
     associated  tenant  leases  are  such  that  non-revenue  producing  tenant
     improvements are immaterial.

   
(7)  The Company's share of estimated pro forma Cash Available for  Distribution
     and the initial amount  available for  distribution to the  shareholders is
     based  on the  Company's  10.91%  partnership  interest  in  the  Operating
     Partnerships.

(8)  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.
    

(9)  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 March 31, 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
Shareholders."

                   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  partnership) or to conduct  business
other  than  through  the  operating  partnership,  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  32.8% at March 31, 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.  At the closing of the Berg  Acquisition the Company intends to establish
the New  Secured  Loan and the New  Credit  Line.  The line of  credit  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 issues 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.

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  of 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 this  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  issues 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 become  exercisable after the first anniversary
of the Berg Acquisition, except that 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. Once in each 12-month period beginning on the first anniversary of
the  closing of the  Offering,  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  permits 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
number.  Generally, each director will serve for a term of one year or until the
next annual meeting at which directors are elected.

CONTRACTUAL ARRANGEMENTS

     In January 1998, the Company entered into an employment  agreement with Mr.
Anderson, Vice President,  Chief Operating Officer and Director,  providing that

agreement) or involuntary termination other than for cause, Mr. Anderson will be
entitled to a severance  payment of $100,000 and a  continuation  of medical and
other group insurance  benefits for six months.  In the event such a termination
occurs  more than 12 months from his hire date,  the  vesting of Mr.  Anderson's
stock  options will  accelerate  and options  which would have vested in the six
month period following the termination date will be vested as of the termination
date.  Additionally,  Mr.  Anderson  acquired  200,000 shares of Common Stock on
March 30, 1998 pursuant to the exercise of an option.  Mr. Anderson's shares are
subject to repurchase by the Company.  The Company loaned Mr. Anderson  $900,000
to purchase the shares.

COMMITTEES OF THE BOARD OF DIRECTORS

   
     AUDIT  COMMITTEE.  The Company has established an Audit Committee that will
consist of at least two Independent  Directors following the consummation of the
UPREIT Transactions  contemplated in this Prospectus/Proxy  Statement. The Audit
Committee was established to make  recommendations  concerning the engagement of
independent public  accountants,  review with the independent public accountants
the plans and results of the audit  engagement,  approve  professional  services
provided by the independent public  accountants,  review the independence of the
independent public  accountants,  consider the range of audit and non-audit fees
and review the adequacy of the Company's internal accounting controls.
    

     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.

                                    -78-
<PAGE>

     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.

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

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-

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:

     of L.P.  Units held by Mr.  Aalgaard  as trustee of the Sonya L. Berg Trust
     and the Sherri L. Berg Trust for which Mr. Aalgaard  possesses no pecuniary

(9)  Does not  include  1,070,626  shares of Common  Stock  which are subject to
     Voting Rights  Agreements.  BBE and the Messrs.  Berg  disclaim  beneficial
     ownership of such shares  because BBE has no  investment  control over such
     shares and no power to vote such  shares.  However,  holders of such shares
     are obligated, pursuant to Voting Rights Agreements, to vote such shares as
     recommended  by Carl E. Berg, as agent for BBE. Both Clyde J. Berg and Carl

     Units held by BBE. If all Common Stock  issuable on exchange of L.P.  Units

(11) Does not include  20,006,025 shares of Common Stock issuable on exchange of
     L.P.  Units held by Mr. Berg as a result of his status as partner or member

                           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.

                                  CALIFORNIA

                       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.

                                  CALIFORNIA

                            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.

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.

                    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
majority  of the  board of  directors  and must be called  by the  secretary  of
Mission West-Maryland at the request in writing of shareholders entitled to cast
a majority of all the votes entitled to be cast at the meeting.

                  ACTIONS BY WRITTEN CONSENT OF SHAREHOLDERS

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.

                                  MARYLAND

                  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
any amendment must be approved by the Required Directors.

                          LIMIT ON SHARE OWNERSHIP

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 is 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 CGCL contains no provisions governing acquisitions of control shares.

                                  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.

Pursuant to the CGCL and the California Articles,  the liability of directors of
the  Company  to the  Company or to any  shareholder  of the  Company  for money
damages for breach of fiduciary duty has been eliminated, except for (a) acts or
omissions  that  involve  intentional  misconduct  or  a  knowing  and  culpable
violation  of the law,  (b) acts or  omissions  that a director  believes  to be
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
Mission  West-Maryland or to any stockholder of Mission  West-Maryland for money
damages  has been  eliminated,  except  for (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.  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
California law.

                                  CALIFORNIA

                    INDEMNIFICATION OF DIRECTORS AND OFFICERS

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.

                                   MARYLAND

                    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."

                                  CALIFORNIA

               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 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-

     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;  which will be freely  transferable  in the public
market without  restriction or further  registration  under the Securities  Act,
unless  purchased by Affiliates of Mission  West-Maryland,  whose shares will be
subject to the resale limitations of Rule 144 and Rule 145(d).

     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 will be accounted for as a recapitalization of the
Berg Properties in a manner similar to reverse acquisition  accounting recording
the  historical  carrying  value of assets with the  exception  of the  Acquired
Properties.  The Acquired Properties will be accounted for as a purchase for the
Fremont  Properties and as a  step-acquisition  for the Kontrabecki  Properties.
Pursuant  to the  step-acquisition  for the  Kontrabecki  Properties,  The  Berg
Group's ownership interest will be recorded at their historical carrying value.
    

                        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

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.
    

                                    -110-
<PAGE>

     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.

    NOTES AND MANAGEMENT'S ASSUMPTIONS TO THE PRO FORMA FINANCIAL STATEMENTS
        FOR THE THREE MONTHS ENDED MARCH 31, 1998 AND FOR THE YEAR ENDED
                          DECEMBER 31, 1997, CONTINUED
                                  (UNAUDITED)
                 (DOLLARS IN THOUSANDS, EXCEPT PER SHARE DATA)

                                   ----------

1.    ORGANIZATION AND BASIS OF PRESENTATION:

   
     The  pro  forma  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 UPREIT Transactions.  The pro forma balance sheet of the
     Company at March 31, 1998 has been  prepared as if the UPREIT  Transactions
     had been  consummated  at March  31,  1998.  The pro  forma  statements  of
     operations  for three  months  ended  March 31, 1998 and for the year ended
     December 31, 1997 have been prepared as if the UPREIT Transactions had been
     consummated  on January  1, 1998 and 1997,  respectively.  In  management's
     opinion,  all  adjustments  necessary  to reflect the effects of the UPREIT
     Transactions  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 March 31, 1998,
     nor actual  results of operations  for three months ended March 31, 1998 or
     for the year ended December 31, 1997, had the UPREIT Transactions  occurred
     on March 31,  1998 and January 1, 1998 or 1997,  respectively,  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, 1997. As the transition period was less
     than one month no separate transition period statements have been prepared.

     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 adjusted to
               reflect the  self-administered  structure  of the Company and the
               additional expenses of being a public company.

          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.   PREFERENTIAL EQUITY DISTRIBUTION:

     In  connection  with the  recapitalization,  members of the Berg Group will
     receive a preferential equity distribution  aggregating  $91,594.  The Berg
     Group's equity in the  underlying  properties,  on a fair market basis,  is
     significantly  in excess  of the book  value  and the  preferential  equity
     distribution represents the return of that value to the Berg Group prior to
     the  contribution  of the  properties  to the  Operating  Partnership.  The
     preferential equity distribution served to reduce the purchase price of the
     10.91% general partnership interest required to be paid by the Company.

4.   THE ACQUISITIONS:

     Concurrent with the  consummation of the UPREIT  Transactions,  the Company
     will purchase the Acquired Properties which include  approximately  144,000
     rentable square feet currently owned by a third party

                                (Continued)
                                   FS-5
<PAGE>

     (the  "Fremont  Properties"),  as well as  approximately  416,000  rentable
     square  feet  consisting  of  properties   held  by  limited   partnerships
     controlled  by  John  Kontrabecki  as  general  partner  (the  "Kontrabecki
     Properties").   Certain   entities   related   to  the   Berg   Group   own
     non-controlling  interests in the  Kontrabecki  Properties.  Any  interests
     related to the Acquired  Properties held by certain entities related to the
     Berg Group have been  reflected in the pro forma  financial  statements  at
     their historical book values.

     In  connection  with  the  acquisition  of  the  Acquired  Properties,  the
     Operating  Partnership will issue 6,694,027  partnership units (issued at a
     value of $4.50 per  partnership  unit)  with a fair value of  $30,123.  The
     Operating   Partnership   will  also  assume   $39,218  of  debt  which  is
     collateralized by these properties,  resulting in a total purchase price of
     $69,341.  Subsequent  to the  closing of the  $130,000  portfolio  mortgage
     facility,   $33,323  of  debt  assumed  in  connection  with  the  Acquired
     Properties will be repaid.

     Upon the closing of the Berg Acquisition, the Acquired Properties will have
     a total book value of $55,389 which includes a partial step-up in basis for
     the interest in the Acquired Properties previously held by entities outside
     the Berg Group. The book value has been allocated  between land,  buildings
     and improvements based upon the historical percentages of costs incurred to
     purchase the land and land improvements of the overall properties' value.

    

5.   PRO FORMA ADJUSTMENTS:

   
          (1)  In  conjunction  with the UPREIT  Transactions,  in September and
               November  1997,  the Company  completed the private  placement of
               200,000  (adjusted  for the 1 for 30  reverse  stock  split)  and
               1,250,000  shares of common  stock,  respectively,  resulting  in
               proceeds to the Company of $6,525. On March 30, 1998, the Company
               sold 200,000 shares at $4.50 per share to an executive officer in
               exchange for a note receivable payable to the Company. Concurrent
               with the UPREIT  Transactions,  the Company  will sell  6,295,058
               shares at $4.50 per share to certain accredited investors for net
               proceeds  of  $28,328.  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.  Operations of the Company
               for the year ended  November 30, 1997,  represent  the results of
               its  liquidation  of prior holdings and are not indicative of its
               future operations.
    

          (2)  The Company will repay amounts borrowed as follows:

                   <S>                               <C>
                   Lines of credit                   $32,953
                   Mortgages notes payable            14,471
                   Notes payable (related parties)    35,144
                                                   ---------
                                                     $82,568
                                                   ---------
                                                   ---------
</TABLE>
    

               The pro forma  statements  of  operations  have been  adjusted to
               reflect historical interest expense to reflect such payment.  The
               early  repayment  of certain  mortgages  is expected to result in
               prepayment penalties of $160.

   
          (3)  The  Company  intends to borrow  $130,000  under a new  portfolio
               mortgage facility that is  collateralized  by certain  properties
               owned by the  Operating  Partnerships  controlled by the Company.
               The Company is currently in negotiations  with a potential lender
               for a loan which  will have an  initial  term of 10 years with an
               interest  rate of  6.56%.  However,  as the  Company  is still in
               negotiations with the potential lender, there can be no assurance
               that the Company will be able to complete this  transaction  or a
               transaction with similar terms.  Management  believes that if the
               Company was required to seek a loan from a new potential  lender,
               the  available  interest rate would  approximate  7% (the current
               prevailing market rate).  Therefore,  the Company has used a rate
               of 7% in the  pro  forma  financial  statements  reflecting  this
               projected loan.

               Additional interest expense associated with these borrowings, net
               of the repayments  discussed  above, in the amounts of $1,459 and
               $5,433 for the pro forma three months  ended March 31, 1998,  and
               for the pro forma year ended December 31, 1997, respectively, has
               been  adjusted  to  reflect  the  new  capital  structure  of the
               Company.

          (4)  As a result of the  transfer of title from the current  owners of
               certain properties to the Operating Partnerships,  transfer taxes
               approximating   $1,000  will  be  paid.   The  Company  does  not
               anticipate full reassessment for property tax purposes due to the
               transactions  associated with the UPREIT  Transactions,  however,
               any  increases  in such taxes  will be passed to the  properties'
               tenants under such tenants' lease agreements.

          (5)  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 eliminated.

          (6)  In connection with the UPREIT Transactions,  the Company will own
               an approximate 10.91% interest in the Operating  Partnerships and
               become  its  sole  general  partner.  Pursuant  to EITF  94-2 the
               initial minority interest is less than zero and;  therefore,  has
               been recorded at zero in the pro forma balance sheet at March 31,
               1998..

          (7)  The  historical  financial  information  for the Company has been
               eliminated as it is not  reflective  of the future  operations of
               the Company.

                        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.

                   (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

                                  (Continued)

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

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

          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 March 31, 1998 and
          1997, and the results of their operations and cash flows for the three
          months ended March 31, 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.

                              THE BERG PROPERTIES
               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.

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  as  described  in Note 1, and is not
intended to be a complete  presentation of the Kontrabecki  Properties'  revenue
and expenses.

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.

reasonable best efforts to take such actions as are necessary or appropriate 
to preserve the status of the Corporation as a REIT; however, the Board of 
Directors may revoke or otherwise terminate the Corporation's REIT election 
pursuant to Section 856(g) of the Code and may determine that compliance with 
any restriction or limitation on stock ownership and transfers set forth in

<PAGE>

Initial Date and prior to the Restriction Termination Date:

          (a) BASIC RESTRICTIONS.

                    (i) (1) No Person, other than any Person in the Berg 
               Group or an Excepted Holder, shall Beneficially Own or 
               Constructively Own shares of Capital Stock in excess of the 
               Ownership Limit, and (2) no Excepted Holder shall Beneficially 
               Own or Constructively Own shares of Capital Stock in excess of 
               the Excepted Holder Limit for such Excepted Holder.

                    (ii) No Person, including all of the Persons in the Berg 
               Group, shall Beneficially or Constructively Own shares of 
               Capital Stock to the extent that such  Beneficial or 
               Constructive Ownership of Capital Stock would result in the 
               Corporation being "closely held" within the meaning of Section 
               856(h) of the Code (without regard to whether the ownership 
               interest is held during the last half of a taxable year), or 
               otherwise failing to qualify as a REIT (including,  but not 
               limited to, Beneficial or Constructive Ownership that would 
               result in the Corporation owning (actually or Constructively) 
               an interest in a tenant that is described in Section 
               856(d)(2)(B) of the Code if the income derived by the 
               Corporation from such tenant would cause the Corporation  to 
               fail to satisfy any of the gross  income requirements of 
               Section 856(c) of the Code).

                    (iii) Notwithstanding any other provisions contained 
               herein, any Transfer of shares of Capital Stock (whether or 
               not such Transfer is the result of a transaction entered into 
               through the facilities of the AMEX or any other national 
               securities exchange or automated inter-dealer quotation 
               system) that, if effective, would result in the Capital Stock 
               being beneficially owned by less than 100 Persons (determined 
               under the principles of Section 856(a)(5) of the Code) shall 
               be void AB INITIO, and the intended transferee shall acquire 
               no rights in such shares of Capital Stock.

          (b) TRANSFER IN TRUST. If any Transfer of shares of Capital Stock 
          (whether or not such Transfer is the result of a transaction 
          entered into through the facilities of the AMEX or any other 
          national securities exchange or automated inter-dealer quotation 
          system) occurs which, if effective, would result in any Person 
          Beneficially Owning or Constructively Owning shares of Capital 
          Stock in violation of Section 7.2.1(a)(i) or (ii),

                    (i) then that number of shares of the Capital Stock the 
               Beneficial or Constructive Ownership of which otherwise would 
               cause such Person to violate Section 7.2.1(a)(i) or 
               (ii)(rounded to the nearest whole share) shall be 
               automatically transferred to a Trust for the benefit of a 
               Charitable Beneficiary, as described in Section 7.3, effective 
               as of the close of business on the Business Day prior to the 
               date of such Transfer, and such Person shall acquire no rights 
               in such shares; or

                    (ii) if the transfer to the Trust described in clause (i) 
               of this sentence would not be effective for any reason to 
               prevent the violation of Section 7.2.1(a)(i) or (ii), then the 
               Transfer

<PAGE>

               of that number of shares of Capital Stock that otherwise would 
               cause any Person to violate Section 7.2.1(a)(i) or (ii) shall 
               be void AB INITIO, and the intended transferee shall acquire 
               no rights in such shares of Capital Stock.

     Section 7.2.2 REMEDIES FOR BREACH. If the Board of Directors of the 
Corporation or any duly authorized committee thereof shall at any time 
determine in good faith that a Transfer or other event has taken place that 
results in a violation of Section 7.2.1 or that a Person intends to acquire 
or has attempted to acquire Beneficial or Constructive Ownership of any 
shares of Capital Stock in violation of Section 7.2.1 (whether or not such 
violation is intended), the Board of Directors or a committee thereof shall 
take such action as it deems advisable to refuse to give effect to or to 
prevent such Transfer or other event, including, without limitation, causing 
the Corporation to redeem shares, refusing to give effect to such Transfer on 
the books of the Corporation or instituting proceedings to enjoin such 
Transfer or other event; PROVIDED, HOWEVER, that any Transfer or attempted 
Transfer or other event in violation of Section 7.2.1 shall automatically 
result in the transfer to the Trust described above, and, where applicable, 
such Transfer (or other event) shall be void AB INITIO as provided above 
irrespective of any action (or non-action) by the Board of Directors or a 
committee thereof.

     Section 7.2.3 NOTICE OF RESTRICTED TRANSFER. Any Person who acquires or 
attempts or intends to acquire Beneficial Ownership or Constructive Ownership 
of shares of Capital Stock that will or may violate Section 7.2.1(a) or any 
Person who would have owned shares of Capital Stock that resulted in a 
transfer to the Trust pursuant to the provisions of Section 7.2.1(b) shall 
immediately give written notice to the Corporation of such event, or in the 
case of such a proposed or attempted transaction, give at least 15 days prior 
written notice, and shall provide to the Corporation such other information 
as the Corporation may request in order to determine the effect, if any, of 
such Transfer on the Corporation's status as a REIT.

     Section 7.2.4 OWNERS REQUIRED TO PROVIDE INFORMATION. From the Initial 
Date and prior to the Restriction Termination Date:

          (a) every owner of more than five percent (or such lower percentage 
     as required by the Code or the Treasury Regulations promulgated 
     thereunder) of the outstanding shares of Capital Stock, within 30 days 
     after the end of each taxable year, shall give written notice to the 
     Corporation stating the name and address of such owner, the number of 
     shares of Capital Stock and other shares of the Capital Stock 
     Beneficially Owned and a description of the manner in which such shares 
     are held. Each such owner shall provide to the Corporation such 
     additional information as the Corporation may request in order to 
     determine the effect, if any, of such Beneficial Ownership on the 
     Corporation's status as a REIT and to ensure compliance with the 
     Ownership Limit; and

          (b) each Person who is a Beneficial or Constructive Owner of 
     Capital Stock and each Person (including the stockholder of record) who 
     is holding Capital Stock for a Beneficial or Constructive Owner shall 
     provide to the Corporation such information as the Corporation may 
     request, in good faith, in order to determine the Corporation's status 
     as a REIT and to comply with requirements of any taxing authority or 
     governmental authority or to determine such compliance.

     Section 7.2.5 REMEDIES NOT LIMITED. Subject to Section 5.7 of the Charter,

<PAGE>

nothing contained in this Section 7.2 shall limit the authority of the Board 
of Directors of the Corporation to take such other action as it deems 
necessary or advisable to protect the Corporation and the interests of its 
stockholders in preserving the Corporation's status as a REIT.

     Section 7.2.6 AMBIGUITY. In the case of an ambiguity in the application 
of any of the provisions of this Section 7.2, Section 7.3, or any definition 
contained in Section 7.1, the Board of Directors of the Corporation shall 
have the power to determine the application of the provisions of this Section 
7.2 or Section 7.3 with respect to any situation based on the facts known to 
it. In the event Section 7.2 or 7.3 requires an action by the Board of 
Directors and the Charter fails to provide specific guidance with respect to 
such action, the Board of Directors shall have the power to determine the 
action to be taken so long as such action is not contrary to the provisions 
of Sections 7.1, 7.2 or 7.3. 

     Section 7.2.7 EXCEPTIONS.

          (a) Subject to Section 7.2.1(a)(ii), the Board of Directors of the
     Corporation, in its sole discretion, may exempt a Person from the Ownership
     Limit, as the case may be, and may establish or increase an Excepted Holder
     Limit for such Person if:

               (i) the  Board of Directors obtains such representations and 
          undertakings from such Person as are reasonably necessary to 
          ascertain that no individual's Beneficial or Constructive Ownership 
          of such shares of Capital Stock will violate Section 7.2.1(a)(ii);

               (ii) such Person does not and represents that it will not own, 
          actually or Constructively, an interest in a tenant of the 
          Corporation (or a tenant of any entity owned or controlled by the 
          Corporation) that would cause the Corporation to own, actually or 
          Constructively, more than a 9.9% interest (as set forth in Section 
          856(d)(2)(B) of the Code) in such tenant and the Board of Directors 
          obtains such representations and undertakings from such Person as 
          are reasonably necessary to ascertain this fact (for this purpose, 
          a tenant from whom the Corporation (or an entity owned or 
          controlled by the Corporation) derives (and is expected to continue 
          to derive) a sufficiently small amount of revenue such that, in the 
          opinion of the Board of Directors of the Corporation, rent from 
          such tenant would not adversely affect the Corporation's ability to 
          qualify as a REIT, shall not be treated as a tenant of the 
          Corporation); and

               (iii) such Person agrees that any violation or attempted 
          violation of such representations or undertakings (or other action 
          which is contrary to the restrictions contained in Sections 7.2.1 
          through 7.2.6) will result in such shares of Capital Stock being 
          automatically transferred to a Trust in accordance with Sections 
          7.2.1(b) and 7.3.

          (b) Prior to granting any exception pursuant to Section 7.2.7(a),  
     the Board of Directors of the Corporation may require a ruling from the 
     Internal Revenue Service, or an opinion of counsel, in either case in 
     form and substance  satisfactory to the Board of Directors in its sole 
     discretion, as it may deem necessary or advisable in order to determine 
     or ensure the Corporation's status as a REIT. Notwithstanding the 
     receipt of any ruling or opinion, the Board of Directors may impose such 
     conditions or restrictions as it deems appropriate in connection with 
     granting such exception.

<PAGE>

          (c) Subject to Section 7.2.1(a)(ii), an underwriter which 
     participates in a public offering or a private placement of Capital 
     Stock (or securities convertible into or exchangeable for Capital Stock) 
     may Beneficially Own or Constructively Own shares of Capital Stock (or 
     securities convertible into or exchangeable for Capital Stock) in excess 
     of the Ownership Limit, but only to the extent necessary to facilitate 
     such public offering or private placement.

          (d) The Board of Directors may only reduce the Excepted Holder 
     Limit for an Excepted Holder: (1) with the written consent of such 
     Excepted Holder at any time, or (2) pursuant to the terms and conditions 
     of the agreements and undertakings entered into with such Excepted 
     Holder in connection with the establishment of the Excepted Holder Limit 
     for that Excepted Holder. No Excepted Holder Limit shall be reduced to a 
     percentage that is less than the Ownership Limit.

     Section 7.2.8 INCREASE IN OWNERSHIP  LIMIT. The Board of Directors may from
time to time increase the Ownership Limit.

     Section 7.2.9 LEGEND. Each certificate for shares of Capital Stock shall 
bear substantially the following legend:

          The shares represented by this certificate are subject to 
     restrictions on Beneficial and Constructive Ownership and Transfer for 
     the purpose of the Corporation's maintenance of its status as a Real 
     Estate Investment Trust under the Internal Revenue Code of 1986, as 
     amended (the "Code"). Subject to certain further restrictions and except 
     as expressly provided in the Corporation's Charter, (i) no Person may 
     Beneficially or Constructively Own shares of Capital Stock of the 
     Corporation in excess of nine percent (9%) of the value of the total 
     outstanding shares of Capital Stock of the Corporation, unless such 
     Person is a member of the Berg Group, or an Excepted Holder (in which 
     case the Excepted Holder Limit shall be applicable); (ii) no Person may 
     Beneficially or Constructively Own Capital Stock that would result in 
     the Corporation being "closely held" under Section 856(h) of the Code or 
     otherwise cause the Corporation to fail to qualify as a REIT; and (iii) 
     no Person may Transfer shares of Capital Stock if such Transfer would 
     result in the Capital Stock of the Corporation being owned by fewer than 
     100 Persons.  Any Person who  Beneficially or Constructively Owns or 
     attempts to Beneficially or Constructively Own shares of Capital Stock 
     which causes or will cause a Person to Beneficially or Constructively 
     Own shares of Capital Stock in excess or in violation of the above 
     limitations must immediately notify the Corporation. If any of the 
     restrictions on transfer or ownership are violated, the shares of 
     Capital Stock represented hereby will be automatically transferred to a 
     Trustee of a Trust for the benefit of one or more Charitable 
     Beneficiaries. In addition, upon the occurrence of certain events, 
     attempted Transfers in violation of the restrictions described above may 
     be void AB INITIO. All capitalized terms in this legend have the 
     meanings defined in the charter of the Corporation, as the same may be 
     amended from time to time, a copy of which, including the restrictions 
     on transfer and ownership, will be furnished to each holder of Capital 
     Stock of the Corporation on request and without charge.

     Instead of the foregoing legend, the certificate may state that the 
Corporation will furnish a full statement about certain restrictions on 
transferability to a stockholder on request and without charge.

<PAGE>

     Section 7.2.10 Notwithstanding any other provision of this Section 7.2, 
the restrictions set forth in this Section 7 other than the restrictions set 
forth in Section 7.2.1(a)(ii), shall not apply to shares of Capital Stock 
owned or acquired in original issuance by members of the Berg Group.

     Section 7.3 TRANSFER OF CAPITAL STOCK IN TRUST.

     Section 7.3.1 OWNERSHIP IN TRUST. Upon any purported Transfer or other 
event described in Section 7.2.1(b) that would result in a transfer of shares 
of Capital Stock to a Trust, such shares of Capital Stock shall be deemed to 
have been transferred to the Trustee as trustee of a Trust for the exclusive 
benefit of one or more Charitable Beneficiaries. Such transfer to the Trustee 
shall be deemed to be effective as of the close of business on the Business 
Day prior to the purported Transfer or other event that results in the 
transfer to the Trust pursuant to Section 7.2.1(b). The Trustee shall be 
appointed by the Corporation and shall be a Person unaffiliated with the 
Corporation and any Prohibited Owner. Each Charitable Beneficiary shall be 
designated by the Corporation as provided in Section 7.3.6.

     Section 7.3.2 STATUS OF SHARES HELD BY THE TRUSTEE. Shares of Capital 
Stock held by the Trustee shall be issued and outstanding shares of Capital 
Stock of the Company. The Prohibited Owner shall have no rights in the shares 
held by the Trustee. The Prohibited Owner shall not benefit economically from 
ownership of any shares held in trust by the Trustee, shall have no rights to 
dividends or other distributions and shall not possess any rights to vote or 
other rights attributable to the shares held in the Trust.

     Section 7.3.3 DIVIDEND AND VOTING RIGHTS. The Trustee shall have all 
voting rights and rights to dividends or other distributions with respect to 
shares of Capital 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 the Corporation that the 
shares of Capital 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 held in the Trust and, subject 
to Maryland law, effective as of the date that the shares of Capital Stock 
have been transferred to the Trustee, 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 the Corporation that the shares of 
Capital Stock have been transferred to the Trustee and (ii) to recast such 
vote in accordance with the desires of the Trustee acting for the benefit of 
the Charitable Beneficiary; provided, however, that if the Corporation has 
already taken irreversible corporate action, then the Trustee shall not have 
the authority to rescind and recast such vote. Notwithstanding the provisions 
of this Article VII, until the Corporation has received notification that 
shares of Capital Stock have been transferred into a Trust, the Corporation 
shall be entitled to rely on its share transfer and other stockholder records 
for purposes of preparing lists of stockholders entitled to vote at meetings, 
determining the validity and authority of proxies and otherwise conducting 
votes of stockholders.

     Section 7.3.4 SALE OF SHARES BY TRUSTEE. Within 20 days of receiving 
notice from the Corporation that shares of Capital Stock have been 
transferred to the

<PAGE>

Trust, the Trustee of the Trust shall sell the shares 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 Section 7.2.1(a). 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 provided in this 
Section 7.3.4. The Prohibited Owner shall receive the lesser of (1) 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., in the case of a gift, devise or other such 
transaction), the Market Price of the shares on the day of the event causing 
the shares to be held in the Trust and (2) the price per share received by 
the Trustee from the sale or other disposition of the shares held in the 
Trust. Any net sales proceeds in excess of the amount payable to the 
Prohibited Owner shall be immediately paid to the Charitable Beneficiary. If, 
prior to the discovery by the Corporation that shares of Capital Stock have 
been transferred to the Trustee, such shares are sold by a Prohibited Owner, 
then (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 this Section 7.3.4, such excess shall be paid to the 
Trustee upon demand.

     Section 7.3.5 PURCHASE RIGHT IN STOCK TRANSFERRED TO THE TRUSTEE. Shares 
of Capital Stock transferred to the Trustee shall be deemed to have been 
offered for sale to the Corporation, 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 the Corporation, or its designee, accepts such offer. The 
Corporation shall have the right to accept such offer until the Trustee has 
sold the shares held in the Trust pursuant to Section 7.3.4. Upon such a sale 
to the Corporation, 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.

     Section 7.3.6 DESIGNATION OF CHARITABLE BENEFICIARIES. By written notice 
to the Trustee, the Corporation shall designate one or more nonprofit 
organizations to be the Charitable Beneficiary of the interest in the Trust 
such that (i) the shares of Capital Stock held in the Trust would not violate 
the restrictions set forth in Section 7.2.1(a) in the hands of such 
Charitable Beneficiary and (ii) each such organization must be described in 
Section 501(c)(3) of the Code and contributions to each such organization 
must be eligible for deduction  under each of Sections 170(b)(1)(A), 2055 and 
2522 of the Code.

     Section 7.4 AMEX TRANSACTIONS. Nothing in this Article VII shall 
preclude the settlement of any transaction entered into through the 
facilities of the AMEX or any other national securities exchange or automated 
inter-dealer quotation system. The fact that the settlement of any 
transaction occurs shall not negate the effect of any other provision of this 
Article VII and any transferee in such a transaction shall be subject to all 
of the provisions and limitations set forth in this Article VII.

     Section 7.5 ENFORCEMENT. The Corporation is authorized specifically to 
seek equitable relief, including injunctive relief, to enforce the provisions 
of this Article VII.

SECTION 2.  ANNUAL MEETING.  An annual meeting of the stockholders for the 
election of directors and the transaction of any business within the powers 
of the Corporation shall be held on a date and at the time set by the Board 
of Directors.

SECTION 3. SPECIAL MEETINGS. The president, chief executive officer or Board 
of Directors may call special meetings of the stockholders. Special meetings 
of stockholders shall also be called by the secretary of the Corporation upon 
the written request of the holders of shares entitled to cast not less than a 
majority of all the votes entitled to be cast at such meeting.  Such request 
shall state the purpose of such meeting and the matters proposed to be acted 
on at such meeting.  The secretary shall inform such stockholders of the 
reasonably estimated cost of preparing and mailing notice of the meeting and, 
upon payment to the Corporation by such stockholders of such costs, the 
secretary shall give notice to each stockholder entitled to notice of the 
meeting.

SECTION 4.  NOTICE.  Not less than ten nor more than 90 days before each 
meeting of stockholders, the secretary shall give to each stockholder 
entitled to vote at such meeting and to each stockholder not entitled to vote 
who is entitled to notice of the meeting written or printed notice stating 
the time and place of the meeting and, in the case of a special meeting or as 
otherwise may be required by any statute, the purpose for which the meeting 
is called, either by mail or by presenting it to such stockholder personally

<PAGE>


residence or usual place of business.  If mailed, such notice shall be deemed 
to be given when deposited in the United States mail addressed to the 
stockholder at his post office address as it appears on the records of the 
Corporation, with postage thereon prepaid.

SECTION 5. SCOPE OF NOTICE. Any business of the Corporation may be transacted 
at an annual meeting of stockholders without being specifically designated in 
the notice, except such business as is required by any statute to be stated 
in such notice.  No business shall be transacted at a special meeting of

SECTION 6. ORGANIZATION.  At every meeting of stockholders, the chairman of 
the board, if there be one, shall conduct the meeting or, in the case of 
vacancy in office or absence of the chairman of the board, one of the 
following officers present shall conduct the meeting in the order stated: the 
vice chairman of the board, if there be one, the president, the vice 
presidents in their order of rank and seniority, or a chairman chosen by the 
stockholders entitled to cast a majority of the votes which all stockholders 
present in person or by proxy are entitled to cast, shall act as chairman, 
and the secretary, or, in his absence, an assistant secretary, or in the 
absence of both the secretary and assistant secretaries, a person appointed 
by the chairman shall act as secretary.

SECTION 7. QUORUM. At any meeting of stockholders, the presence in person or 
by proxy of stockholders entitled to cast a majority of all the votes 
entitled to be cast at such meeting shall constitute a quorum; but this 
section shall not affect any requirement under any statute or the charter of 
the Corporation for the vote necessary for the adoption of any measure.  If, 
however, such quorum shall not be present at any meeting of the stockholders, 
the stockholders entitled to vote at such meeting, present in person or by 
proxy, shall have the power to adjourn the meeting from time to time to a 
date not more than 120 days after the original record date without notice

quorum shall be present, any business may be transacted which might have been 
transacted at the meeting as originally notified.

SECTION 8.  VOTING.  A plurality of all the votes cast at a meeting of 
stockholders duly called and at which a quorum is present shall be sufficient 
to elect a director.  Each share may be voted for as many individuals as 
there are directors to be elected and for whose election the share is 
entitled to be voted. A majority of the votes cast at a meeting of 
stockholders duly called and at which a quorum is present shall be sufficient 
to approve any other matter which may properly come before the meeting, 
unless more than a majority of the votes cast is required by statute or by 
the charter of the Corporation.  Unless otherwise provided in the charter, 
each outstanding share, regardless of class, shall be entitled to one vote on 
each matter submitted to a vote at a meeting of stockholders.

SECTION 9. PROXIES.  A stockholder may cast the votes entitled to be cast by 
the shares of the stock owned of record by him either in person or by proxy 
executed in writing by the stockholder or by his duly authorized agent. Such 
proxy shall be filed with the secretary of the Corporation before or at the 
time of the meeting.  No proxy shall be valid after eleven months from the 
date of its execution, unless otherwise provided in the proxy.

SECTION 10.  VOTING OF STOCK BY CERTAIN HOLDERS.  Stock of the Corporation 
registered in the name of a corporation, partnership, trust or other entity, 
if entitled to be voted, may be voted by the president or a vice president, a

<PAGE>

general partner or trustee thereof, as the case may be, or a proxy appointed 
by any of the foregoing individuals, unless some other person who has been 
appointed to vote such stock pursuant to a bylaw or a resolution of the 
governing body of such corporation or other entity or agreement of the 
partners of a partnership presents a certified copy of such bylaw, resolution 
or agreement, in which case such person may vote such stock. Any director or 
other fiduciary may vote stock registered in his name as such fiduciary, 
either in person or by proxy.

Shares of stock of the Corporation directly or indirectly owned by it shall 
not be voted at any meeting and shall not be counted in determining the total 
number of outstanding shares entitled to be voted at any given time, unless 
they are held by it in a fiduciary capacity, in which case they may be voted 
and shall be counted in determining the total number of outstanding shares at 
any given time.

The Board of Directors may adopt by resolution a procedure by which a 
stockholder may certify in writing to the Corporation that any shares of 
stock registered in the name of the stockholder are held for the account of a 
specified person other than the stockholder.  The resolution shall set forth 
the class of stockholders who may make the certification, the purpose for 
which the certification may be made, the form of certification and the 
information to be contained in it; if the certification is with respect to a 
record date or closing of the stock transfer books, the time after the record 
date or closing of the stock transfer books within which the certification 
must be received by the Corporation; and any other provisions with respect to 
the procedure which the Board of Directors considers necessary or desirable.  
On receipt of such certification, the person specified in the certification 
shall be regarded as, for the purposes set forth in the certification, the 
stockholder of record of the specified stock in place of the stockholder who 
makes the certification.

Notwithstanding any other provision of the charter of the Corporation or 
these Bylaws, Title 3, Subtitle 7 of the Corporations and Associations 
Article of the Annotated Code of Maryland (or any successor statute) shall 
not apply to any acquisition by any person of shares of stock of the 
Corporation.  This section may be repealed, in whole or in part, at any time, 
whether before or after an acquisition of control shares and, upon such 
repeal, may, to the extent provided by any successor bylaw, apply to any 
prior or subsequent control share acquisition.

SECTION 11.  INSPECTORS.  At any meeting of stockholders, the chairman of the 
meeting may appoint one or more persons as inspectors for such meeting.  Such 
inspectors shall ascertain and report the number of shares represented at the 
meeting based upon their determination of the validity and effect of proxies, 
count all votes, report the results and perform such other acts as are proper 
to conduct the election and voting with impartiality and fairness to all the 
stockholders.

Each report of an inspector shall be in writing and signed by him or by a 
majority of them if there is more than one inspector acting at such meeting.  
If there is more than one inspector, the report of a majority shall be the 
report of the inspectors.  The report of the inspector or inspectors on the 
number of shares represented at the meeting and the results of the voting 
shall be PRIMA FACIE evidence thereof.

SECTION 12. NOMINATIONS AND PROPOSALS BY STOCKHOLDERS.

     (A) ANNUAL MEETINGS OF STOCKHOLDERS.

<PAGE>

          (1)  Nominations of persons for election to the Board of Directors 
          and the proposal of business to be considered by the stockholders 
          may be made at an annual meeting of stockholders (i) pursuant to 
          the Corporation's notice of meeting, (ii) by or at the direction of 
          the Board of Directors, (iii) by any stockholder of the Corporation 
          who was a stockholder of record both at the time of giving of 
          notice provided for in this Section 12(a) and at the time of the 
          annual meeting, who is entitled to vote at the meeting and who 
          complied with the notice procedures set forth in this Section 
          12(a), or (iv) as provided below in Section 14.

          (2) For nominations or other business to be properly brought before 
          an annual meeting by a stockholder pursuant to clause (iii) of 
          paragraph (a)(1) of this Section 12, the stockholder must have 
          given timely notice thereof in writing to the secretary of the 
          Corporation and such other business must otherwise be a proper 
          matter for action by stockholders.  To be timely, a stockholder's 
          notice shall be delivered to the secretary at the principal 
          executive offices of the Corporation not later than the close of 
          business on the 60th day nor earlier than the close of business on 
          the 90th day prior to the first anniversary of the preceding year's 
          annual meeting; provided, however, that in the event that the date 
          of the annual meeting is advanced by more than 30 days or delayed 
          by more than 60 days from such anniversary date or if the 
          Corporation has not previously held an annual meeting, notice by 
          the stockholder to be timely must be so delivered not earlier than 
          the close of business on the 90th day prior to such annual meeting 
          and not later than the close of business on the later of the 60th 
          day prior to such annual meeting or the tenth day following the day 
          on which public announcement of the date of such meeting is first 
          made by the Corporation.  In no event shall the public  
          announcement of a postponement or adjournment of an annual meeting 
          to a later date or time commence a new time period for the giving 
          of a stockholder's notice as described above. Such stockholder's 
          notice shall set forth (i) as to each person whom the stockholder 
          proposes to nominate for election or reelection as a director all 
          information relating to such person that is required to be 
          disclosed in solicitations of proxies for election of directors in 
          an election contest, or is otherwise required, in each case 
          pursuant to Regulation 14A under the Securities Exchange Act of 
          1934, as amended (the "Exchange Act") (including such person's 
          written consent to being named in the proxy statement as a nominee 
          and to serving as a director if elected); (ii) as to any other 
          business that the stockholder proposes to bring before the meeting, 
          a brief description of the business desired to be brought before 
          the meeting, the reasons for conducting such business at the 
          meeting and any material interest in such business of such 
          stockholder and of the beneficial owner, if any, on whose behalf 
          the proposal is made; and (iii) as to the stockholder giving the 
          notice and the beneficial owner, if any, on whose behalf the 
          nomination or proposal is made, (x) the name and address of such 
          stockholder, as they appear on the Corporation's books, and of such 
          beneficial owner and (y) the number of shares of each class of 
          stock of the Corporation which are owned beneficially and of record 
          by such stockholder and such beneficial owner.

          (3) Notwithstanding anything in the second sentence of paragraph
          (a)(2) of this Section 12 to the contrary, in the event that the


<PAGE>


          number of directors to be elected to the Board of Directors is 
          increased and there is no public announcement by the Corporation 
          naming all of the nominees for director or specifying the size of 
          the increased Board of Directors at least 70 days prior to the 
          first anniversary of the preceding year's annual meeting, a 
          stockholder's notice required by this Section 12(a) shall also be 
          considered timely, but only with respect to nominees for any new 
          positions created by such increase, if it shall be delivered to the 
          secretary at the principal executive offices of the Corporation not 
          later than the close of business on the tenth day following the day 
          on which such public announcement is first made by the Corporation.

     (B) SPECIAL MEETINGS OF STOCKHOLDERS. Only such business shall be 
     conducted at a special meeting of stockholders as shall have been 
     brought before the meeting pursuant to the Corporation's notice of 
     meeting. Nominations of persons for election to the Board of Directors 
     may be made at a special meeting of stockholders at which directors are 
     to be elected (i) pursuant to the Corporation's notice of meeting, (ii) 
     by or at the direction of the Board of Directors, (iii) provided that 
     the Board of Directors has determined that directors shall be elected at 
     such special meeting, by any stockholder of the Corporation who is a 
     stockholder of record both at the time of giving of notice provided for 
     in this Section 12(b) and at the time of the special meeting, who is 
     entitled to vote at the meeting and who complied with the notice 
     procedures set forth in this Section 12(b) or (iv) in any event, as 
     provided in Section 14. In the event the Corporation calls a special 
     meeting of stockholders for the purpose of electing one or more 
     directors to the Board of Directors, any such stockholder may nominate a 
     person or persons (as the case may be) for election to such position as 
     specified in the Corporation's notice of meeting, if the stockholder's 
     notice containing the information required by paragraph (a)(2) of this 
     Section 12 shall be delivered to the secretary at the principal 
     executive offices of the Corporation not earlier than the close of 
     business on the 90th day prior to such special meeting and not later 
     than the close of business on the later of the 60th day prior to such 
     special meeting or the tenth day following the day on which public 
     announcement is first made of the date of the special meeting and of the 
     nominees proposed by the Board of Directors to be elected at such 
     meeting. In no event shall the public announcement of a postponement or 
     adjournment of a special meeting to a later date or time commence a new 
     time period for the giving of a stockholder's notice as described above.

     (C) GENERAL.

          (1) Only such persons who are nominated in accordance with the 
          procedures set forth in this Section 12 or in Section 14 shall be 
          eligible to serve as directors and only such business shall be 
          conducted at a meeting of stockholders as shall have been brought 
          before the meeting in accordance with the procedures set forth in 
          this Section 12. The chairman of the meeting shall have the power 
          and duty to determine whether a nomination or any business proposed 
          to be brought before the meeting was made or proposed, as the case 
          may be, in accordance with the procedures set forth in this Section 
          12 and, if any proposed nomination or business is not in compliance 
          with this Section 12, to declare that such nomination or proposal 
          shall be disregarded.

          (2) For purposes of this Section 12, "public announcement" shall mean

<PAGE>

          disclosure in a press release reported by the Dow Jones News Service,
          Associated Press or comparable news service or in a document publicly
          filed by the Corporation with the Securities and Exchange Commission
          pursuant to Section 13, 14 or 15(d) of the Exchange Act.

          (3) Notwithstanding the foregoing provisions of this Section 12, a 
          stockholder shall also comply with all applicable requirements of 
          state law and of the Exchange Act and the rules and regulations 
          thereunder with respect to the matters set forth in this Section 
          12. Nothing in this Section 12 shall be deemed to affect any rights 
          of stockholders to request inclusion of proposals in, nor any right 
          of the Corporation to omit a proposal from, the Corporation's proxy 
          statement pursuant to Rule 14a-8 under the Exchange Act.

SECTION 13. VOTING BY BALLOT. Voting on any question or in any election may 
be by voice unless the presiding officer shall order or any stockholder shall 
demand that voting be by ballot.

SECTION 14. NOMINATION AND ELECTION OF BERG GROUP DIRECTOR REPRESENTATIVES. 
The Board of Directors shall include among its members two individuals 
nominated by Carl E. Berg, Clyde J. Berg, the members of their respective 
immediate families and certain entities controlled by Carl E. Berg and/or 
Clyde J. Berg which are Berg & Berg Enterprises, Inc., Baccarat Cambrian 
Partnership, Baccarat Fremont Developers LLC and DeAnza Office Partners 
(collectively the "Berg Group") and their affiliates (the "Berg Group Board 
Representatives") so long as the members of the Berg Group, together with 
their affiliates (other than the Corporation or Mission West Properties, 
L.P., Mission West Properties, L.P. I, Mission West Properties, L.P. II or 
Mission West Properties, L.P. III (collectively, the "Operating 
Partnership"), in the aggregate, own at least 15% of the total number of 
shares of voting stock of the Corporation (taking into account the 
conversion,  exchange or exercise of all outstanding warrants,  options, 
convertible securities and other rights to acquire voting stock of the 
Corporation and all units of limited partnership interests in the Operating 
Partnership exchangeable or redeemable for Common Stock or other voting stock 
of the Corporation (without regard to any ownership limit set forth in the 
Corporation's charter, the Bylaws or any agreement) (the "Fully-Diluted" 
number of shares)). The Berg Group shall exercise the right to name directors 
provided in this Section 14 by submitting to the Board of Directors prior to 
any annual meeting or other meeting at which directors are elected the 
name(s) of the Berg Group nominee(s). In the event the Berg Group and their 
affiliates (other than the Company and the Operating Partnership), in the 
aggreagate, own less than 15%, but at least 10%, of the Fully-Diluted number 
of shares, the Berg Group may nominate only one director to be a Berg Group 
Board Representative.

A Berg Group Board Representative may not be replaced, whether by election or 
filling of a vacancy, by any individual who has not been nominated by the 
Berg Group. In the event of doubt concerning the identification of the 
nominees of the Berg Group, prior to any meeting of stockholders at which 
directors are to be elected, the chief executive officer or presiding 
officer, if a different person, shall ask the Berg Group members to cast 
ballots, and the one or two individuals, as the case may be, selected by the 
holders of a majority of all of the Fully-Diluted shares held by the Berg 
Group members shall be deemed to be the nominees of the Berg Group.

As used in this Section 14 the term "affiliate" shall have the meaning 
ascribed to it by Rule 12b-2 promulgated under the Exchange Act.

     (b) Until the date on which the Berg Group and their affiliates (other 
     than the Company and the Operating Partnership) own less than 15% of the 
     Fully-Diluted number of shares, all meetings of the Board of Directors 
     shall require the presence of Carl E. Berg or the presence of an 
     individual whom he designates to replace him on the Board of Directors 
     (the "Designee"). Mr. Berg shall submit a written statement identifying 
     the Designee to the Company from time to time to permit identification 
     of the Designee in the event that death, disability or other event 
     results in a vacancy on the Board of Directors as a result of Mr. Berg's 
     inability to serve as a director. Mr. Berg may amend the statement at 
     his sole discretion.

     (c) Subject to the foregoing, the directors present at a meeting which 
     has been duly called and convened may continue to transact business 
     until adjournment, notwithstanding the withdrawal of enough directors to 
     leave less than a quorum.

SECTION 7. VOTING.

     (a) Except as provided in paragraph (a) and (b) of this Section 7, the 
     action of the majority of the directors present at a meeting at which a 
     quorum is present shall be the action of the Board of Directors, unless 
     the concurrence of a greater proportion is required for such action by 
     applicable statute.

     (b) The approval of more than 75% of all of the directors then serving 
     on the Board of Directors shall be required to approve (i) acquisitions 
     of assets or conduct of any business other than, in either case, through 
     the Operating Partnership, (ii) the termination of the Corporation's 
     status as a REIT or (iii) the Corporation's incurring indebtedness for 
     borrowed funds exceeding 50% of the market value of the outstanding 
     Common Stock determined as if all outstanding units of limited 
     partnership interests in the Operating Partnership had been converted 
     into Common Stock, plus the market value of all other publicly traded 
     securities of the Corporation outstanding from time to time, plus the 
     total debt of the Corporation and the Operating Partnership.

SECTION 8. TELEPHONE MEETINGS. Directors may participate in a meeting by 
means of a conference telephone or similar communications equipment if all 
persons participating in the meeting can hear each other at the same time. 
Participation in a meeting by these means shall constitute presence in person 
at the meeting.

SECTION 9. INFORMAL ACTION BY DIRECTORS. Any action required or permitted to 
be taken at any meeting of the Board of Directors may be taken without a 
meeting, if a consent in writing to such action is signed by each director 
and such written consent is filed with the minutes of proceedings of the 
Board of Directors.

SECTION 10. VACANCIES. If for any reason any or all the directors cease to be 
directors, such event shall not terminate the Corporation or affect these 
Bylaws or the powers of the remaining directors hereunder (even if fewer than 
three directors remain). Any vacancy on the Board of Directors for any cause 
other than an increase in the number of directors shall be filled by a 
majority of the remaining directors, even if such majority is less than a 
quorum. Any vacancy in the number of directors created by an increase in the 
number of directors may be filled by a majority vote of the entire Board of 
Directors. Any individual so

<PAGE>

elected as director shall hold office until the next annual meeting of 
stockholders and until his successor is elected and qualifies.

SECTION 11. COMPENSATION. Directors shall receive a salary for their services 
as directors as set forth in a resolution of the Board of Directors, and may 
receive compensation per year and/or per meeting and/or per visit to real 
property or other facilities owned or leased by the Corporation and for any 
service or activity they performed or engaged in as directors. Directors may 
be reimbursed for expenses of attendance, if any, at each annual, regular or 
special meeting of the Board of Directors or of any committee thereof and for 
their expenses, if any, in connection with each property visit and any other 
service or activity they performed or engaged in as directors; but nothing 
herein contained shall be construed to preclude any directors from serving 
the Corporation in any other capacity and receiving compensation therefor.

SECTION 12. LOSS OF DEPOSITS. No director shall be liable for any loss which 
may occur by reason of the failure of the bank, trust company, savings and 
loan association, or other institution with whom moneys or stock have been 
deposited.

SECTION 13. SURETY BONDS. Unless required by law, no director shall be 
obligated to give any bond or surety or other security for the performance of 
any of his duties.

SECTION 14. RELIANCE. Each director, officer, employee and agent of the 
Corporation shall, in the performance of his duties with respect to the 
Corporation, be fully justified and protected with regard to any act or 
failure to act in reliance in good faith upon the books of account or other 
records of the Corporation, upon an opinion of counsel or upon reports made 
to the Corporation by any of its officers or employees or by the adviser, 
accountants, appraisers or other experts or consultants selected by the Board 
of Directors or officers of the Corporation, regardless of whether such 
counsel or expert may also be a director.

SECTION 15. CERTAIN RIGHTS OF DIRECTORS, OFFICERS, EMPLOYEES AND AGENTS. The 
directors shall have no responsibility to devote their full time to the 
affairs of the Corporation. Except as provided otherwise in any agreement 
between the Corporation and the affected person, any director or officer, 
employee or agent of the Corporation, in his personal capacity or in a 
capacity as an affiliate, employee, or agent of any other person, or 
otherwise, may have business interests and engage in business activities 
similar to or in addition to or in competition with those of or relating to 
the Corporation.

manner as notice for special meetings of the Board of Directors. A majority 
of the members of the committee shall constitute a quorum for the transaction 
of business at any meeting of the committee. The act of a majority of the 
committee members present at a meeting shall be the act of such committee. 
The Board of Directors may designate a chairman of any committee, and such 
chairman may fix the time and place of its meeting unless the Board shall 
otherwise provide. In the absence of any member of any such committee, the 
members thereof present at any meeting, whether or not they constitute a

member. Each committee shall keep minutes of its proceedings.

proceedings of such committee.

SECTION 6. VACANCIES. Subject to the provisions hereof, the Board of

may be removed by the Board of Directors if in its judgment the best 
interests of the Corporation would be served thereby, but such removal shall

removed. Any officer

of the Corporation may resign at any time by giving written notice of his 
resignation to the Board of Directors, the chairman of the board, the 
president or the secretary. Any resignation shall take effect at any time 
subsequent to the time specified therein or, if the time when it shall become 
effective is not specified therein, immediately upon its receipt. The 
acceptance of a resignation shall not be necessary to make it effective 
unless otherwise stated in the resignation. Such resignation shall be without 
prejudice to the contract rights, if any, of the Corporation.

If required by the Board of Directors, the treasurer shall give the

                                     STOCK

SECTION 1. CERTIFICATES. Each stockholder shall be entitled to a certificate 
or certificates which shall represent and certify the number of shares of 
each class of stock held by him in the Corporation. Each certificate shall be 
signed by the chief executive officer, the president or a vice president and 
countersigned by the secretary or an assistant secretary or the treasurer or 
an assistant treasurer and may be sealed with the seal, if any, of the 
Corporation. The signatures may be either manual or facsimile. Certificates 
shall be consecutively numbered; and if the Corporation shall, from time to 
time, issue several classes of stock, each class may have its own number 
series. A certificate is valid and may be issued whether or not an officer 
who signed it is still an officer when it is issued. Each certificate 
representing shares which are restricted as to their transferability or 
voting powers, which are preferred or limited as to their dividends or as to 
their allocable portion of the assets upon liquidation or which are 
redeemable at the option of the Corporation, shall have a statement of such 
restriction, limitation, preference or redemption provision,  or a summary 
thereof,  plainly stated on the certificate. If the Corporation has authority 
to issue stock of more than one class, the certificate shall contain on the 
face or back a full statement or summary of the designations and any 
preferences, conversion and other rights, voting  powers,  restrictions,  
limitations  as to  dividends  and other distributions, qualifications and 
terms and conditions of redemption of each class of stock and, if the 
Corporation is authorized to issue any preferred or special class in series, 
the differences in the relative rights and preferences between the shares of 
each series to the extent they have been set and the authority of the Board 
of Directors to set the relative rights and preferences of subsequent series. 
In lieu of such statement or summary, the certificate may state that the 
Corporation will furnish a full statement of such information to any 
stockholder upon request and without charge. If any class of stock is 
restricted by the Corporation as to transferability, the certificate shall 
contain a full statement of the restriction or state that the Corporation 
will furnish information about the restrictions to the stockholder on request 
and without charge.

SECTION 2. TRANSFERS. Upon surrender to the Corporation or the transfer agent 
of the Corporation of a stock certificate duly endorsed or accompanied by 
proper evidence of succession, assignment or authority to transfer, the 
Corporation shall issue a new certificate to the person entitled thereto, 
cancel the old certificate and record the transaction upon its books.

The Corporation shall be entitled to treat the holder of record of any share 
of stock as the holder in fact thereof and, accordingly, shall not be bound 
to recognize any equitable or other claim to or interest in such share or on 
the

<PAGE>

part of any other person, whether or not it shall have express or other 
notice thereof, except as otherwise provided by the laws of the State of 
Maryland.

Notwithstanding the foregoing, transfers of shares of any class of stock will 
be subject in all respects to the charter of the Corporation and all of the 
terms and conditions contained therein, and to the terms of any written 
agreement between the Corporation and a stockholder with respect to share 
transfers subject to the terms of such agreement.

SECTION 3. REPLACEMENT CERTIFICATE. Any officer designated by the Board of 
Directors may direct a new certificate to be issued in place of any 
certificate previously issued by the Corporation alleged to have been lost, 
stolen or destroyed upon the making of an affidavit of that fact by the 
person claiming the certificate to be lost, stolen or destroyed. When 
authorizing the issuance of a new certificate, an officer designated by the 
Board of Directors may, in his discretion and as a condition precedent to the 
issuance thereof, require the owner of such lost, stolen or destroyed 
certificate or the owner's legal representative to advertise the same in such 
manner as he shall require and/or to give bond, with sufficient surety, to 
the Corporation to indemnify it against any loss or claim which may arise as 
a result of the issuance of a new certificate.

SECTION 4. CLOSING OF TRANSFER BOOKS OR FIXING OF RECORD DATE. The Board of 
Directors may set, in advance, a record date for the purpose of determining 
stockholders entitled to notice of or to vote at any meeting of stockholders 
or determining stockholders entitled to receive payment of any dividend or 
the allotment of any other rights, or in order to make a determination of 
stockholders for any other proper purpose. Such date, in any case, shall not 
be prior to the close of business on the day the record date is fixed and 
shall be not more than 90 days and, in the case of a meeting of stockholders, 
not less than ten days, before the date on which the meeting or particular 
action requiring such determination of stockholders of record is to be held 
or taken.

In lieu of fixing a record date, the Board of Directors may provide that the 
stock transfer books shall be closed for a stated period but not longer than 
20 days. If the stock transfer books are closed for the purpose of 
determining stockholders entitled to notice of or to vote at a meeting of 
stockholders, such books shall be closed for at least ten days before the 
date of such meeting.

If no record date is fixed and the stock transfer books are not closed for 
the determination of stockholders, (a) the record date for the determination 
of stockholders entitled to notice of or to vote at a meeting of stockholders 
shall be at the close of business on the day on which the notice of meeting 
is mailed or the thirtieth day before the meeting, whichever is the closer 
date to the meeting; and (b) the record date for the determination of 
stockholders entitled to receive payment of a dividend or an allotment of any 
other rights shall be the close of business on the day on which the 
resolution of the directors, declaring the dividend or allotment of rights, 
is adopted.

When a determination of stockholders entitled to vote at any meeting of 
stockholders has been made as provided in this section, such determination 
shall apply to any adjournment thereof, except when (i) the determination has 
been made through the closing of the transfer books and the stated period of 
closing has expired or (ii) the meeting is adjourned to a date more than 120 
days after the record date fixed for the original meeting, in either of which 
case a new record date shall be determined as set forth herein.

<PAGE>

SECTION 5. STOCK LEDGER. The Corporation shall maintain at its principal 
office or at the office of its counsel, accountants or transfer agent, an 
original or duplicate share ledger containing the name and address of each 
stockholder and the number of shares of each class held by such stockholder.

SECTION 6. FRACTIONAL STOCK; ISSUANCE OF UNITS. The Board of Directors may 
issue fractional stock or provide for the issuance of scrip, all on such 
terms and under such conditions as they may determine. Notwithstanding any 
other provision of the charter or these Bylaws, the Board of Directors may 
issue units consisting of different securities of the Corporation. Any 
security issued in a unit shall have the same characteristics as any 
identical securities issued by the Corporation, except that the Board of 
Directors may provide that for a specified period securities of the 
Corporation issued in such unit may be transferred on the books of the 
Corporation only in such unit.

                                 ARTICLE VIII

the Corporation may be authorized and declared by the Board of Directors, 
subject to the provisions of law and the charter of the Corporation. 
Dividends and other distributions may be paid in cash, property or stock of 
the Corporation, subject to the provisions of law and the charter.

SECTION 2.  CONTINGENCIES.  Before payment of any dividends or other 
distributions, there may be set aside out of any assets of the Corporation 
available for dividends or other distributions such sum or sums as the Board 
of Directors may from time to time, in its absolute discretion, think proper 
as a reserve fund for contingencies, for equalizing dividends or other 
distributions, for repairing or maintaining any property of the Corporation 
or for such other purpose as the Board of Directors shall determine to be in 
the best interest of the Corporation, and the Board of Directors may modify 
or abolish any such reserve in the manner in which it was created.

                                   ARTICLE X

                               INVESTMENT POLICY

Subject to the provisions of the charter of the Corporation, the Board of 
Directors may from time to time adopt, amend, revise or terminate any policy 
or policies with respect to investments by the Corporation as it shall deem 
appropriate in its sole discretion.

Board of Directors may authorize one or more duplicate seals and provide for 
the custody thereof.

SECTION 2. AFFIXING SEAL. Whenever the Corporation is permitted or required 
to affix its seal to a document, it shall be sufficient to meet the 
requirements of any law, rule or regulation relating to a seal to place the 
word "(SEAL)" adjacent to the signature of the person authorized to execute 
the document on behalf of the Corporation.

                                  ARTICLE XII

                    INDEMNIFICATION AND ADVANCE OF EXPENSES

To the maximum extent permitted by Maryland law in effect from time to time, 
the Corporation shall indemnify and, without requiring a preliminary 
determination of the ultimate entitlement to indemnification, shall pay or 
reimburse reasonable expenses in advance of final disposition of a proceeding 
to (a) any individual who is a present or former director or officer of the 
Corporation and who is made a party to the proceeding by reason of his 
service in that capacity or (b) any individual who, while a director of the 
Corporation and at the request of the Corporation, 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 Corporation may, with the approval of its Board of 
Directors, provide such indemnification and advance for expenses to a person 
who served a predecessor of the Corporation in any of the capacities 
described in (a) or (b) above and to any employee or agent of the Corporation 
or a predecessor of the Corporation.

Neither the amendment nor repeal of this Article, nor the adoption or 
amendment of any other provision of the Bylaws or charter of the Corporation 
inconsistent with this Article, shall apply to or affect in any respect the 
applicability of the preceding paragraph with respect to any act or failure 
to act which occurred prior to such amendment, repeal or adoption.

                                 ARTICLE XIII

                               WAIVER OF NOTICE

Whenever any notice is required to be given pursuant to the charter of the 
Corporation or these Bylaws or pursuant to applicable law, a waiver thereof 
in writing, signed by the person or persons entitled to such notice, whether 
before or after the time stated therein, shall be deemed equivalent to the 
giving of such notice. Neither the business to be transacted at nor the 
purpose of any meeting need be set forth in the waiver of notice, unless 
specifically required by statute. The attendance of any person at any meeting 
shall constitute a waiver of notice of such meeting, except where such person 
attends a meeting for the express purpose of objecting to the transaction of 
any business on the ground that the meeting is not lawfully called or 
convened.

ARTICLE 4. CAPITAL CONTRIBUTIONS.

     4.1 CAPITAL CONTRIBUTIONS OF THE PARTNERS.

     A. At the time of the execution of this Agreement, the Partners have made
the Adjusted Contributions, or shall make the Capital Contributions contemplated
by the Acquisition Agreement, as set forth in Appendix I to this Agreement. Each
Limited Partner shall own L.P. Units in the amount set forth for such Partner in
Appendix I and shall have a Percentage Interest in the Partnership as set forth
in Appendix I, which shall be adjusted in Appendix I from time to time by the
General Partner to the extent necessary to reflect accurately exchanges,
additional Capital Contributions,  the issuance of additional Partnership
Interests, the exercise of Put Rights with respect to L.P. Units or similar
events having an effect on any Partner's Percentage Interest.

     B. The number of Units held by the General Partner, in its capacity as
general partner, shall be deemed to be the General Partner Interest. Except as
provided in Sections 4.2, 10.5 and 13.3, the Partners shall have no obligation
to make any additional Capital Contributions.

     4.2 ADDITIONAL FUNDS; RESTRICTIONS ON COMPANY.

     A. The sums of money required to finance the business and affairs of the
Partnership shall be derived from the initial Capital Contributions made to the
Partnership by the Company as set forth in the Acquisition Agreement and from
funds generated from the operation and business of the Partnership including,
without limitation, distributions directly or indirectly received by the
Partnership from Available Cash provided by the Operating Partnership. In the
event additional financing is needed from sources other than as set forth in the
preceding sentence for any reason, subject to the provisions of Sections 8.8 and
8.9, the General Partner may, in its discretion, in such amounts and at such
times as it solely shall determine to be necessary or appropriate, obtain
additional funds for the Operating Partnership which shall be allocated to each
of the partnerships included therein, including the Partnership, pro rata in
proportion to the ratio of the number of Units then outstanding in each such
Partnership to the total number of L.P. Units then outstanding in the Operating
Partnership taken as a whole ("Pro Rata Share"). Accordingly, to the extent of
such Pro Rata Share of the Partnership and subject to Section 8.9 and any other
limitations contained in this Agreement or the Acquisition Agreement, the
General Partner may, (i) cause the Partnership to issue additional Partnership
Interests and admit additional Limited Partners to the Partnership in accordance
with Section 4.3; (ii) make additional Capital Contributions to the Partnership
(subject to the provisions of Section 4.2B); (iii) cause the Partnership to
borrow money, enter into loan arrangements, issue debt securities, obtain
letters of credit or otherwise borrow money on a secured or unsecured basis; or
(iv) make loans to the Partnership (subject to Section 4.2B). In no event shall
the Limited Partners be required to make any additional Capital Contributions or
any loan to, or otherwise provide any financial accommodation for the benefit
of, the Partnership pursuant to any such permitted action by the General
Partner, except insofar as a Limited Partner has exercised its New Equity
Financing Right pursuant to Section 8.8.

     B. Except as agreed otherwise at the time by vote or written consent of the
L.P. Unit Majority: (i) the Company shall lend to the Partnership its Pro Rata
Share of the proceeds of or consideration received by the Company from all loans
and advances to the Company pursuant to any financial borrowing arrangement on
the same financial terms and conditions, including interest rate and repayment


<PAGE>


schedule, as shall be applicable with respect to or incurred in connection with
the issuance of such loans and advances to the Company (which the Partnership
may, in turn, lend to any other partnership constituting part of the Operating
Partnership); (ii) in the case of Equity Securities senior or junior to the
Common Stock as to dividends and distributions on liquidation, which are not
convertible into Common Stock as of the issuance date, the Company shall
contribute to the Partnership the proceeds of or consideration (including any
property or other non-cash assets) received for such Securities and the proceeds
of, or consideration received from, any subsequent exercise, exchange or
conversion thereof (if applicable), and shall receive from the Partnership, new
Partnership Interests in the Partnership in consideration therefor with the same
financial terms and conditions,  including  dividend,  dividend priority,
liquidation preference, conversion and redemption rights, as are applicable to
such Equity Securities; (iii) in the case of Common Stock, or other Equity
Securities convertible into Common Stock as of the issuance date, including,
without limitation, shares of Common Stock or other Equity Securities issued
upon exercise of options issued under the Stock Option Plan or any other
Employee Benefit Plan of the Company, the Company shall contribute to the
Partnership the proceeds of or consideration (including any property or other
non-cash  assets) received for such Securities and the proceeds of, or
consideration received from, any subsequent exercise, exchange or conversion
thereof (if applicable), and shall receive from the Partnership a number of
additional Units of General Partner Interest in consideration therefor equal to
the product of (x) the number of shares of Common Stock or other Equity
Securities issued by the Company, multiplied by (y) the Exchange Factor in
effect on the date of such contribution; and (iv) in the case of Common Stock or
other Equity Securities issued upon the exercise or surrender of rights under a
stock option, warrant, or any other right for which the Company does not receive
proceeds, and issues less than the number of shares of Common Stock or other
Equity Securities subject to such option, warrant or other right to the holder
thereof retaining the excess of such shares as payment of the purchase price (a
"net exercise"), or where the Company uses the proceeds received pursuant to a
Dividend Reinvestment Plan to acquire shares of Common Stock or other Equity
Securities to be issued to the shareholder exercising such right, the Company
shall receive from the Partnership a number of additional Units of General
Partner Interest equal to the actual number of shares of Common Stock or other
Equity Securities so issued to the shareholder multiplied by the Exchange
Factor.

     4.3 ISSUANCE OF ADDITIONAL PARTNERSHIP INTERESTS; ADMISSION OF ADDITIONAL
LIMITED PARTNERS. In addition to any Partnership Interests issuable by the
Partnership pursuant to Section 4.2, and subject to the provisions of Sections
8.8 and 8.9, the General Partner is authorized to cause the Partnership to issue
additional Partnership Interests (or options therefor) in the form of L.P. Units
or other Partnership Interests senior or junior to the L.P. Units to any Persons
at any time or from time to time, for consideration per Unit of Partnership
Interest not less than the Common Stock Price determined at the initial issuance
date divided by the Exchange Factor, and on such other terms and conditions, as
the General Partner shall establish provided, however, that (i) each partnership
included in the Operating Partnership shall effect its Pro Rata Share of such
issuance, (ii) such issuance does not cause the Partnership to become, with
respect to any Employee Benefit Plan subject to Title I of ERISA or Section 4975
of the Code, a "party in interest" (as defined in Section 3(14) of ERISA) or a
"disqualified person" (as defined in Section 4975(e) of the Code); and (iii)
such issuance does not cause any portion of the assets of the Partnership to
constitute assets of any Employee Benefit Plan subject to Section 2510.3-101 of
the regulations of the United States Department of Labor. Subject to the


<PAGE>


limitations set forth in the preceding sentence, the General Partner may take
such steps as it, in its reasonable discretion, deems necessary or appropriate
to admit any Person as a Limited Partner of the Partnership, including, without
limitation, amending the Certificate, Appendix I or any other provision of this
Agreement.

     4.4 REPURCHASE OF COMPANY EQUITY SECURITIES. In the event the Company shall
elect to purchase from its shareholders shares of Common Stock for the purpose
of delivering such shares to satisfy an obligation  under any Dividend
Reinvestment Plan or Employee Benefit Plan adopted by the Company, or shall
repurchase any other Equity Securities of the Company pursuant to any other
share repurchase obligation or arrangement undertaken by the Company with any
Company shareholder, including preferred stock redemptions, the purchase price
paid by the Company for such shares and any other expenses incurred by the
Company in connection with such purchase shall be considered expenses of the
Partnership and shall be reimbursed to the Company, subject to the condition
that: (i) if such shares subsequently are to be sold by the Company, the Company
shall pay to the Partnership any proceeds received by the Company for such
shares of Common Stock or other Equity Securities (provided that an exchange of
shares of Common Stock for L.P. Units pursuant to the Exchange Rights Agreement
would not be considered a sale for such purposes); and (ii) if such shares are
not re-transferred by the Company within 30 days after the purchase thereof, the
General Partner shall cause the Partnership to cancel the number of Units of
General Partner Interest held by the Company determined by multiplying (x) the
quotient obtained by dividing the total amount deemed paid by the Partnership by
the Common Stock Price determined as of the repurchase date, by (y) the Exchange
Factor in effect on the date of such repurchase.

     4.5 NO THIRD PARTY BENEFICIARY. No creditor or other third party having
dealings with the Partnership shall have the right to enforce the right or
obligation of any Partner to make Capital Contributions or loans or to pursue
any other right or remedy hereunder or at law or in equity, it being understood
and agreed that the provisions of this Agreement shall be solely for the benefit
of, and may be enforced solely by, the parties hereto and their respective
successors and assigns.

     4.6 NO INTEREST; NO RETURN. No Partner shall be entitled to interest on its
Capital Contribution or on such Partner's Capital Account. Except as provided in
Section 8.7 or Article 13 of this Agreement, or by law, no Partner shall have
any right to demand or receive the return of its Capital Contribution from the
Partnership.

ARTICLE 5. DISTRIBUTIONS.

     5.1 REGULAR DISTRIBUTIONS. Except for distributions pursuant to Section
13.2 in connection with the dissolution and liquidation of the Partnership, and
subject to the provisions of Sections 5.3, 5.4 and 5.5, the General Partner
shall cause the Partnership to distribute, from time to time as determined by
the General Partner, but in any event not less frequently than once each
Quarter, the Partnership's Pro Rata Share of all Available Cash, to the
Partners, in accordance with each Partner's respective Percentage Interest;
provided, however, that in no event may a Limited Partner receive a distribution
of Available Cash with respect to a L.P. Unit, if such Limited Partner is
entitled to receive a distribution out of such Available Cash with respect to a
share of Common Stock for which such L.P. Unit has been exchanged.

     5.2 QUALIFICATION AS A REIT. The General Partner shall be entitled to cause


<PAGE>


the Partnership to distribute to the General Partner the Partnership's Pro Rata
Share of Available Cash distributed by the Operating Partnership to enable the
General Partner to pay shareholder dividends that will (i) satisfy the REIT
Requirements for distributions to shareholders, and (ii) avoid any federal
income or excise tax liability of the General Partner; provided, however, the
General Partner is not bound to comply with this covenant to the extent such
distributions would violate applicable Delaware law.

     5.3 WITHHOLDING. With respect to any withholding tax or other similar tax
liability or obligation to which the Partnership may be subject as a result of
any act or status of any Partner or to which the Partnership becomes subject
with respect to any Unit, the Partnership shall have the right to withhold
amounts of Available Cash distributable to such Partner or with respect to such
Units, to the extent of the amount of such withholding tax or other similar tax
liability or obligation pursuant to the provisions contained in Section 10.5.

     5.4 ADDITIONAL PARTNERSHIP INTERESTS. If the Partnership issues Partnership
Interests in accordance with Section 4.2 or 4.3 which are entitled to certain
distribution priorities, Section 5.1 shall be amended, as necessary, to reflect
the distribution priority of such Partnership Interests and corresponding
amendments shall be made to the provisions of Appendix II.

     5.5 DISTRIBUTIONS UPON LIQUIDATION. Proceeds from a Terminating Capital
Transaction and any other cash received or reductions in reserves made after
commencement of the liquidation of the Partnership shall be distributed to the

ARTICLE 7. MANAGEMENT AND OPERATION OF BUSINESS.

     7.1 MANAGEMENT.

     A. Except as otherwise expressly provided in this Agreement, and subject to
the provisions of Section 8.9, all management powers over the business and
affairs the Partnership are and shall be exclusively vested in the General
Partner, and no Limited Partner shall have any right to participate in or
exercise control or management power over the business and affairs of the
Partnership. The General Partner may not be removed by the Limited Partners,
with or without cause. In addition to the powers now or hereafter granted a
general partner of a limited partnership under the Act or which are granted to
the General Partner under any other provision of this Agreement, the General
Partner shall have full power and authority to make contracts, sign documents,
conduct litigation, acquire and convey property, hire employees, consultants and
professionals, raise capital, borrow funds, incur liabilities, invest funds,
comply with all applicable laws, and do all other things deemed necessary or
desirable by the General Partner to conduct the business of the Partnership on
behalf of the Partnership; to exercise all powers set forth in Section 3.2, and
to effectuate the purposes set forth in Section 3.1, provided that any exercise
of the foregoing  rights and powers must be consistent  with the REIT
Requirements.

     B. Except as provided in Section 8.9, each of the Limited Partners agrees


<PAGE>


that the General Partner is authorized to execute, deliver and perform the
agreements and transactions on behalf of the Partnership without any further
act, approval or vote of the Partners, notwithstanding any other provision of
this Agreement to the fullest extent permitted under the Act or other applicable
law, rule or regulation. The execution, delivery or performance by the General
Partner or the Partnership of any agreement authorized or permitted under this
Agreement shall not constitute a breach by the General Partner of any duty that
the General Partner may owe the Partnership or the Limited Partners or any other
Persons under this Agreement or of any duty stated or implied by law or equity.

     C. At all times from and after the date hereof, in accordance with the
provisions of the Acquisition Agreement, the General Partner may cause the
Partnership to establish and maintain at any and all times working capital
accounts and other cash or similar balances in such amount as the General
Partner, in its sole and absolute discretion, deems appropriate and reasonable
from time to time. Such accounts may include funds of the General Partner and
the other partnerships in the Operating Partnership, which the General Partner
shall be free to commingle.

     D. In exercising its authority under this Agreement, the General Partner
shall take into account the tax consequences to any Partner of any action taken
by it and shall select the alternative which appears at the time to present the
least adverse tax consequences to the Limited Partners. By way of example, but
not of limitation: If the General Partner decides to refinance (directly or
indirectly) any outstanding indebtedness of the Partnership, the General Partner
shall use reasonable efforts to structure such refinancing in a manner that
minimizes any adverse tax consequences resulting therefrom to the Limited
Partners. The General Partner and the Partnership shall not have liability to a
Limited Partner under any circumstances as a result of an income tax liability
incurred by such Limited Partner as a result of a necessary action (or inaction)
by the General Partner taken pursuant to its authority under and in accordance
with this Agreement where avoiding the resulting adverse tax consequences to a
Limited Partner was not reasonably practicable under the circumstances.

     7.2 CERTIFICATE OF LIMITED PARTNERSHIP. The General Partner shall file the
[AMENDED CERTIFICATE] [CERTIFICATE] with the Secretary of State of Delaware as
required by the Act. The General Partner shall use all reasonable efforts to
cause to be filed such other certificates or documents as may be reasonable and
necessary or appropriate for the formation, continuation, qualification and
operation of a limited partnership (or a partnership in which the limited
partners have limited liability) in the State of Delaware and any other state,
or the District of Columbia, in which the Partnership may elect to do business
or own property. To the extent that such action is determined by the General
Partner to be reasonable and necessary or appropriate, the General Partner shall
file amendments to and restatements of the Certificate and do all of the things
to maintain the Partnership as a limited partnership (or a partnership in which
the limited partners have limited liability) under the laws of the State of
Delaware and each other state, or the District of Columbia, in which the
Partnership may elect to do business or own property. Subject to the terms of
Section 8.5A(iv) hereof, the General Partner shall not be required, before or
after filing, to deliver or mail a copy of the Certificate or any amendment
thereto to any Limited Partner.

     7.3 REIMBURSEMENT OF THE GENERAL PARTNER AND THE COMPANY.

     A. Except as provided in this Section 7.3 and elsewhere in this Agreement
(including the provisions of Articles 5 and 6 regarding distributions, payments,


<PAGE>


and allocations to which it may be entitled), the General Partner shall not be
compensated for its services as general partner of the Partnership.

     B. The General Partner, shall be reimbursed on a monthly basis, or such
other basis as it may determine in its sole and absolute discretion, for all
expenses that it incurs relating to the ownership and operation of, or for the
benefit of, the Partnership; provided, that the amount of any such reimbursement
shall be reduced by any interest earned by the General Partner with respect to
bank accounts or other instruments or accounts held by it in its name. Such
reimbursement shall be in addition to any reimbursement made as a result of
indemnification pursuant to Section 7.6.

     7.4 OUTSIDE ACTIVITIES OF THE GENERAL PARTNER. The General Partner shall
not directly or indirectly enter into or conduct any business other than in
connection with the ownership, acquisition, development and disposition of
Partnership Interests and the management of the business of the Partnership, and
such activities as are incidental thereto. The General Partner and any
Affiliates of the General Partner may acquire Limited Partner Interests and
shall be entitled to exercise all rights of a Limited Partner relating to such
Limited Partner Interests.

     7.5 CONTRACTS WITH AFFILIATES.

     A. The Partnership may lend or contribute funds or other assets to its
Subsidiaries or other Persons in which it has an equity investment and such
Persons may borrow funds from the Partnership, on terms and conditions
established in the sole and absolute discretion of the General Partner. The
foregoing authority shall not create any right or benefit in favor of any
Subsidiary or any other Person.

     B. Except as provided in Section 7.4, the Partnership may Transfer assets
to joint ventures, other partnerships, corporations or other business entities
in which it is or thereby becomes a participant upon such terms and subject to
such conditions consistent with this Agreement and applicable law as the General
Partner, in its sole and absolute discretion, believes are advisable.

     C. Except as expressly  permitted  by this  Agreement or otherwise
contemplated by the Acquisition Agreement, neither the General Partner nor any
of its Affiliates shall sell, Transfer or convey any property to, or purchase
any property from, the Partnership, directly or indirectly, except pursuant to
transactions that are determined by the General Partner in good faith to be fair
and reasonable.

     D. Except as provided otherwise in Section 8.9, the General Partner, in its
sole and absolute discretion and without the approval of the Limited Partners,
may propose and adopt, on behalf of the Partnership, Employee Benefit Plans
funded by the Partnership for the benefit of employees of the General Partner,
the Partnership, Subsidiaries of the Partnership or any Affiliate of any of them
in respect of services performed, directly or indirectly, for the benefit of the
Partnership, the General Partner, or any Subsidiaries of the Partnership.

     E. The General Partner is expressly authorized to enter into, in the name
and on behalf of the Partnership, a "right of first opportunity" or "right of
first offer" arrangement,  non-competition  agreements and other conflict
avoidance agreements with various Affiliates of the Partnership and the General
Partner, on such terms as the General Partner, in its sole and absolute
discretion, believes are advisable.

     7.6 INDEMNIFICATION.

     A. To the fullest extent permitted by Delaware law, the Partnership shall
indemnify each Indemnitee from and against any and all losses, claims, damages,
liabilities,  joint or several, expenses (including,  without limitation,
reasonable attorneys' fees and other legal fees and expenses), judgments, fines,
settlements, and other amounts arising from any and all claims, demands,
actions, suits or proceedings, civil, criminal, administrative or investigative,
that relate to the operations of the Partnership or the Company as set forth in
this Agreement, in which such Indemnitee may be involved, or is threatened to be
involved, as a party or otherwise, except to the extent it is finally determined
by a court of competent jurisdiction, from which no further appeal may be taken,
that such Indemnitee's action constituted  intentional acts or omissions
constituting willful misconduct or fraud. Without limitation, the foregoing
indemnity shall extend to any liability of any Indemnitee, pursuant to a loan
guaranty or otherwise for any indebtedness of the Partnership or any Subsidiary
of the Partnership (including, without limitation, any indebtedness which the
Partnership or any Subsidiary of the Partnership has assumed or taken subject
to), except with respect to Partnership debt that has been assumed or guaranteed
by an Indemnitee in its capacity as a Limited Partner. The General Partner is
hereby authorized and empowered, on behalf of the Partnership, to enter into one
or more indemnity agreements consistent with the provisions of this Section 7.6
in favor of any Indemnitee having or potentially having liability for any such
indebtedness. Any indemnification pursuant to this Section 7.6 shall be made
only out of the assets of the Partnership, and neither the General Partner nor
any Limited Partner shall have any obligation to contribute to the capital of
the Partnership, or otherwise provide funds, to enable the Partnership to fund
its obligations under this Section 7.6.

     B. Reasonable expenses incurred by an Indemnitee who is a party to a
proceeding shall be paid or reimbursed by the Partnership in advance of the
final disposition of the proceeding.

     C. The indemnification provided by this Section 7.6 shall be in addition to
any other rights to which an Indemnitee or any other Person may be entitled
under any agreement, pursuant to any vote of the Partners, under the Company's
Articles of Incorporation, as a matter of law, or otherwise, and shall continue
as to an Indemnitee who has ceased to serve in such capacity unless otherwise
provided in a written agreement pursuant to which such Indemnities are
indemnified.

     D. The Partnership may, but shall not be obligated to, purchase and
maintain insurance, on behalf of the Indemnities and such other Persons as the
General Partner shall determine, against any liability that may be asserted
against or expenses that may be incurred by such Person in connection with the
Partnership's activities, regardless of whether the Partnership would have the
power to indemnify such Person against such liability under the provisions of
this Agreement.

     E. For purposes of this Section 7.6, the Partnership shall be deemed to
have requested an Indemnitee to serve as fiduciary of an Employee Benefit Plan
whenever the performance by such Indemnitee of its duties to the Partnership
also imposes duties on, or otherwise involves services by, such Indemnitee to
the plan or participants or beneficiaries of the plan; excise taxes assessed on
an Indemnitee with respect to an Employee Benefit Pan pursuant to applicable law
shall constitute fines within the meaning of this Section 7.6; and actions taken


<PAGE>


or omitted by the Indemnitee with respect to an Employee Benefit Plan in the
performance of its duties for a purpose reasonably believed by it to be in the
interest of the participant and beneficiaries of the plan shall be deemed to be
for a purpose which is not opposed to the best interests of the Partnership.

     F. In no event may an Indemnitee subject any of the Limited Partners to
personal liability by reason of the indemnification provisions set forth in this
Agreement.

     G. An Indemnitee shall not be denied indemnification in whole or in part
under this Section 7.6 because the Indemnitee had an interest in the transaction
with respect to which the indemnification applies if the transaction was
otherwise permitted by the terms of this Agreement.

     H. The provisions of this Section 7.6 are for the benefit of the
Indemnitees, their heirs, successors, assigns and administrators and shall not
be deemed to create any rights for the benefit of any other Persons. Any
amendment, modification or repeal of this Section 7.6 or any provision hereof
shall be prospective only and shall not in any way affect the Partnership's
liability to any Indemnitee under this Section 7.6, as in effect immediately
prior to such amendment, modification, or repeal with respect to claims arising
from or relating to matters occurring, in whole or in part, prior to such
amendment, modification or repeal, regardless of when such claims may arise or
be asserted.

     I. The provisions of this Section 7.6 shall be inapplicable to any
investigation, claim, suit, or proceeding, or the portion thereof, which
concerns claims for breach of contract between the Partnership and a Person
contracting other than in such Person's capacity as a Partner, or as an officer
or director of the General Partner.

     J. No provision of this Section 7.6 shall be construed as permitting any 
contract or transaction which is prohibited by the provisions of Section 
9.2(b) of the Acquisition Agreement.

     7.7 LIABILITY OF THE GENERAL PARTNER.

     A. Notwithstanding anything to the contrary set forth in this Agreement,
the General Partner and its officers and directors shall not be liable for
monetary damages to the Partnership, any Partners or any Assignees for losses
sustained or liabilities incurred as a result of errors in judgment or of any
act or omission, if the General Partner acted in good faith; provided, however,
the foregoing shall not be deemed to exculpate the Company from any liability
the Company may have under the Acquisition Agreement.

     B. Subject to its obligations and duties as General Partner set forth in
Section 7.1A hereof, the General Partner may exercise any of the powers granted
to it by this Agreement and perform any of the duties imposed upon it hereunder
either directly or by or through its agent. The General Partner shall not be
liable for any acts or omissions on the part of any such agent, except in
circumstances for which the General Partner may be liable under Section 7.7A or
would not be subject to indemnification under Section 7.6.

     C. Any amendment, modification or repeal of this Section 7.7 or any
provision hereof shall be prospective only and shall not in any way affect the
limitations on the General Partner's and its officers' and directors' liability
to the Partnership and the Limited Partners under this Section 7.7 as in effect


<PAGE>


immediately prior to such amendment, modification or repeal with respect to
claims arising from or relating to matters occurring, in whole or in part, prior
to such amendment, modification or repeal, regardless of when such claims may
arise or be asserted.

     7.8 LIMITED PARTNERS' RIGHT TO BRING DERIVATIVE LAWSUITS. Any Limited
Partner may bring an action on behalf of the Partnership, as permitted under the
Act and the laws of the State of Delaware, to recover a judgment in favor of the
Partnership if the General Partner has refused to bring the action or if an
effort to cause the General Partner to bring the action is not likely to
succeed.

     7.9 OTHER MATTERS CONCERNING THE GENERAL PARTNER.

     A. The General Partner may rely and shall be protected in acting, or
refraining from acting, upon any resolution, certificate, statement, instrument,
opinion, report, notice, request, consent, order, bond, debenture, or other
paper or document believed by it in good faith to be genuine and to have been
signed or presented by the proper party or parties.

     B. The General Partner may consult with legal counsel, accountants,
appraisers, management consultants, investment bankers, architects, engineers,
environmental consultants and other consultants and advisers selected by it, and
any act taken or omitted to be taken in reliance upon the opinion of such
Persons as to matters which such General Partner reasonably believes to be
within such Person's professional or expert competence shall be conclusively
presumed to have been done or omitted in good faith and in accordance with such
opinion.

     C. The General Partner shall have the right, in respect of any of its
powers or obligations hereunder, to act through any of its duly authorized
officers and duly appointed attorneys-in-fact. Each such attorney shall, to the
extent provided by the General Partner in the power of attorney, have full power
and authority to do and perform all and every act and duty which is permitted or
required to be done by the General Partner hereunder.

     D. Notwithstanding any other provisions of this Agreement or the Act, any
action of the General Partner on behalf of the Partnership or any decision of
the General Partner to refrain from acting on behalf of the Partnership,
undertaken in the good faith belief that such action or omission is necessary or
advisable in order (i) to protect the ability of the Company to continue to
qualify as a REIT; or (ii) to avoid the Company incurring any taxes under
Section 857 or Section 4981 of the Code, is expressly authorized under this
Agreement and is deemed approved by all of the Limited Partners.

     7.10 TITLE TO PARTNERSHIP ASSETS. Title to Partnership assets, whether
real, personal or mixed and whether tangible or intangible, shall be deemed to
be owned by the Partnership as an entity, and no Partner, individually or
collectively, shall have any ownership interest in such Partnership assets or
any portion thereof. Title to any or all of the Partnership assets may be held
in the name of the Partnership, the General Partner or one or more nominees, as
the General Partner may determine, including Affiliates of the General Partner.
The General Partner hereby declares and warrants that any Partnership asset for
which legal title is held in the name of the General Partner or any nominee or
Affiliate of the General Partner shall be held by the General Partner for the
use and benefit of the Partnership in accordance with the provisions of this
Agreement; provided, that the General Partner shall use its best efforts to


<PAGE>


cause beneficial and record title to such assets to be vested in the Partnership
as soon as reasonably practicable. All Partnership assets shall be recorded as
the property of the Partnership in its books and records, irrespective of the
name in which legal title to such Partnership assets is held.

     7.11 RELIANCE BY THIRD PARTIES. Notwithstanding anything to the contrary in
this Agreement, any Person dealing with the Partnership shall be entitled to
assume that the General Partner has full power and authority, without consent or
approval of any other Partner or Person, to encumber, sell or otherwise use in
any manner any and all assets of the Partnership and to enter into any contracts
on behalf of the Partnership, and take any and all actions on behalf of the
Partnership, and such Person shall be entitled to deal with the General Partner
as if the General Partner were the Partnership's sole party in interest, both
legally and beneficially. Each Limited Partner hereby waives any and all
defenses or other remedies which may be available against such Person to
contest, negate or disaffirm any action of the General Partner in connection
with any such dealing. In no event shall any Person dealing with the General
Partner or its representatives be obligated to ascertain that the terms of this
Agreement have been complied with or to inquire into the necessity or expedience
of any act or action of the General Partner or its representatives. Each and
every certificate, document or other instrument executed on behalf of the
Partnership by the General Partner or its representatives shall be conclusive
evidence in favor of any and every Person relying thereon or claiming thereunder
that: (i) at the time of the execution and delivery of such certificate,
document or instrument, this Agreement was in full force and effect; (ii) the
Person executing and delivering such certificate, document or instrument was
duly authorized and empowered to do so for and on behalf of the Partnership; and
(iii) such certificate, document or instrument was duly executed and delivered
in accordance with the terms and provisions of this Agreement and is binding
upon the Partnership.

ARTICLE 8. RIGHTS AND OBLIGATIONS OF LIMITED PARTNERS.

     8.1 LIMITATION OF LIABILITY. The Limited Partners shall have no liability
under this Agreement except as expressly provided in this Agreement, including
Sections 10.5 and 13.3 hereof, or under the Act. Notwithstanding the preceding
sentence, each Limited Partner shall have the right, but not the obligation, to
guarantee a portion of the indebtedness of the Partnership in accordance with
the terms of the Acquisition Agreement.

     8.2 MANAGEMENT OF BUSINESS. No Limited Partner or Assignee (other than the
General Partner, any of its Affiliates or any officer, director, employee, agent
or trustee of the General Partner, the Partnership or any of their Affiliates,
in their capacity as such) shall take part in the operation, management or
control (within the meaning of the Act) of the Partnership's business, transact
any business in the Partnership's name or have the power to sign documents for
or otherwise bind the Partnership. The transaction of any such business by the
General Partner, any of its Affiliates or any officer, director, employee,
partner, agent or trustee of the General Partner, the Partnership or any of
their Affiliates, in their capacity as such, shall not affect, impair or
eliminate the limitations on the liability of the Limited Partners or Assignees
under this Agreement.

     8.3 OUTSIDE ACTIVITIES OF LIMITED PARTNERS. Subject to any agreements
entered into pursuant to Section 7.5 hereof and any other agreements entered
into by a Limited Partner or its Affiliates with the Partnership or any of its
Subsidiaries including the Acquisition Agreement, any Limited Partner (other


<PAGE>


than the Company) and any officer, director, employee, agent, trustee, Affiliate
or shareholder of any Limited Partner (other than the Company) shall be entitled
to and may have business interests and engage in business activities in addition
to those relating to the Partnership,  including business interests and
activities that are in direct competition with the Partnership or that are
enhanced by the activities of the Partnership. Neither the Partnership nor any
Partners shall have any rights by virtue of this Agreement in any business
ventures of any Limited Partner or Assignee which are permitted within the scope
of this Section 8.3. None of the Limited Partners (other than the Company) nor
any other Person shall have any rights by virtue of this Agreement or the
Partnership relationship established hereby in any business ventures of any
other Person and such Person shall have no obligation pursuant to this Agreement
to offer any interest in any such business ventures to the Partnership, any
Limited Partner or any such other Person, even if such opportunity is of a
character which, if presented to the Partnership, any Limited Partner or such
other Person, could be taken by such Person.

     8.4 RETURN OF CAPITAL. Except in connection with the exercise of Exchange
Rights or Put Rights, no Limited Partner shall be entitled to the withdrawal or
return of its Capital Contribution, except to the extent of distributions made
pursuant to this Agreement or upon termination of the Partnership as provided
herein. Except to the extent provided by Appendix II, or as otherwise expressly
provided in this Agreement, no Limited Partner or Assignee shall have priority
over any other Limited Partner or Assignee, either as to the return of Capital
Contributions or as to profits, losses or distributions.

     8.5 RIGHTS OF LIMITED PARTNERS RELATING TO THE PARTNERSHIP.

     A. In addition to the other rights provided by this Agreement or by the
Act, and except as limited by Section 8.5B hereof, each Limited Partner shall
have the right, for a purpose reasonably related to such Limited Partner's
interest as a limited partner in the Partnership, upon written demand with a
statement of the purpose of such demand and at such Limited Partner's own
expense (including such reasonable copying and administrative charges as the
General Partner may establish from time to time): (i) to obtain a copy of the
most recent annual and quarterly reports filed by the Company with the SEC
pursuant to the Exchange Act; (ii) to obtain a copy of the Partnership's
federal, state and local income tax returns for each Partnership Year; (iii) to
obtain a current list of the name and last known business, residence or mailing
address of each Partner; (iv) to obtain a copy of this Agreement and the
Certificate and all amendments and/or restatements thereto, together with
executed copies of all powers of attorney pursuant to which this Agreement, the
Certificate and all amendments and/or restatements thereto have been executed;
and (v) to obtain true and full information regarding the amount of cash and a
description and statement of any other property or services contributed by each
Partner and which each Partner has agreed to contribute in the future, and the
date on which each became a Partner.

     B. Notwithstanding any other provision of this Section 8.5, the General
Partner may keep confidential from the Limited Partners, for such period of time
as the General Partner determines in its sole and absolute discretion to be
reasonable, any information that (i) the General Partner reasonably believes to
be in the nature of trade secrets or other confidential information, the
disclosure of which the General Partner in good faith believes is not in the
best interests of the Partnership or the Company or could damage the Partnership
or its business; or (ii) the Partnership is required by law or by agreements
with an unaffiliated third party to keep confidential.


<PAGE>


     8.6 EXCHANGE RIGHTS. The Limited Partners may exchange all or a portion of
their L.P. Units for shares of Common Stock on the terms and subject to the
conditions and restrictions contained in the Exchange Rights Agreement.

     8.7 PUT RIGHTS.

     A. Upon the terms and subject to the conditions of this Agreement, each
Limited Partner (other than Carl E. Berg and Clyde J. Berg with respect to all
L.P. Units owned by them beneficially as of the Effective Date) shall have the
right to tender to the Partnership outstanding L.P. Units no more than once
during any 12-month period commencing after ___________,  ___ 1999. The
Partnership shall purchase properly tendered L.P. Units for cash at a price (the
"Tender Price") equal to the average market value of the Common Stock price as
of the date the Limited Partner delivers to the General Partner, at the address
provided in Appendix II, a completed and duly executed Letter of Transmittal in
the form attached as Exhibit A to the Exchange Rights Agreement, and any other
documents required by the Letter of Transmittal. Only a tender in this manner
will constitute a valid tender of L.P. Units pursuant to this Section 8.7A. The
General Partner shall make all determinations as to the validity and form of any
tender of L.P. Units in accordance with the provisions of this Agreement, and
upon rejection of a tender, shall give the tendering holder written notice of
such rejection, which shall include the reasons therefor. Unless otherwise
agreed by the General Partner or as provided in Section 8.7C, tenders of L.P.
Units pursuant to this Section 8.7A shall be irrevocable and shall not be
subject to withdrawal or modification.

     B. Within 15 days after the valid tender of L.P. Units pursuant to Section
8.7A, the Company may make an election to purchase such L.P. Units itself with
cash of the Company (the "Cash Election"). If with respect to any tender of L.P.
Units pursuant to this Section 8.7, the Company makes the Cash Election, then
within 90 days after such tender the Company shall pay to the tendering Limited
Partner an aggregate amount of cash equal to the purchase price of the tendered
L.P. Units with available cash, borrowed funds or the proceeds of an offering of
new shares of Common Stock. Upon acquiring the L.P. Units, the Company may cause
the Partnership to retire the L.P. Units and convert them to the same number of
Units of General Partner Interest, and the General Partner shall amend Appendix
I accordingly.

     C. Notwithstanding the foregoing, if the purchase price for the L.P. Units
tendered by a Limited Partners in one year exceeds $1,000,000, the Partnership
or the Company shall be entitled to reduce proportionally the number of L.P.
Units to be acquired from each Tendering Partner so that the total purchase
price does not exceed $1,000,000 if the Company so elects. In addition, if the
Company does not timely make the Cash Election, the Partnership shall deliver
the purchase price for the tendered L.P. Units to the Limited Partner within 45
days after the Letter of Transmittal was delivered to the General Partner. The
General Partner may defer payment of the purchase price until such time not to
exceed 120 days after the valid tender of L.P. Units pursuant to Section 8.7A as
the Partnership has adequate Available Cash after payment of the purchase price,
in the reasonable judgment of the General Partner, to fund current distributions
necessary for the Company to satisfy the REIT Requirements following the waiver
by the Company of its right to make the Cash Election. In such event, the
General Partner shall give the tendering Limited Partner written notice of its
decision to defer the payment with a calculation supporting the General
Partner's determination within 20 days after the Letter of Transmittal was
delivered to the General Partner. Upon receiving such notice, the Limited


<PAGE>


Partner may withdraw the tender. In addition, the Limited Partner may instead
exercise its rights under the Exchange Rights Agreement. If a Limited Partner
tenders L.P. Units pursuant to this Section 8.7, the Limited Partner shall pay
the amount of any additional documentary, stamp or similar issue or transfer tax
which is due, and shall be responsible for all income or other taxes as a result
of such exchange.

     D. Each tender of L.P. Units shall constitute a representation and warranty
by the tendering Limited Partner of each of the representations and warranties
set forth in the form of Letter of Transmittal.

     E. Until the holder of L.P. Units tendered pursuant to Section 8.7 has
received cash in exchange therefor, such Limited Partner shall continue to hold
and own such L.P. Units for all purposes of this Agreement.

     8.8 NEW EQUITY FINANCING RIGHTS.

     A. If the General Partner determines that it is in the best interests of
the Partnership to obtain additional funds through the issuance of additional
Partnership Interests, the General Partner shall first offer to the Limited
Partners in each of the partnerships comprising the Operating Partnership,
including the Partnership, the right of first refusal to purchase that portion
of such additional Partnership Interests which their respective numbers of L.P.
Units bear to the total number of outstanding L.P. Units in the Operating
Partnership. The General Partner shall make this offer pursuant to a written
notice describing the offering price, class or series of Partnership Interest,
and all other material terms of the offer. Such notice shall be sent to each
Limited Partner at the address reflected in Appendix I, as amended. The Limited
Partners shall have 10 days from the date of such notice to elect to purchase
any such additional Partnership Interests. Such election shall be made pursuant
to a written subscription form specifying the number of Units of additional
Limited Partnership Interests the Limited Partner intends to acquire and the
total purchase price therefor, and shall be signed by the Limited Partner and
delivered to the General Partner at the address set forth on Appendix I. After
such 10-day period, the General Partner shall be free to offer any additional
Limited Partnership Interests on substantially similar terms to non-Partners and
Partners alike.

     B. The foregoing right of the Limited Partners to acquire additional equity
interests offered by the Partnership ("New Equity Financing Right") shall not
apply to any offering (i) which is part of a transaction in which the Limited
Partners had the ability to exercise their New Equity Financing Rights under the
Acquisition Agreement with respect to an offering of Equity Securities by the
Company, (ii) in connection with a merger or other business combination subject
to approval by the L.P. Unit Majority pursuant to Section 8.9, (iii) to a Person
in connection with the acquisition of property or services by the Partnership
from such Person, or (iv) of any Partnership Interest upon conversion of an
outstanding Equity Security of the Partnership, any Partnership Subsidiary, or
the Company.

     8.9 MATTERS REQUIRING L.P. UNIT MAJORITY APPROVAL. The consent of the L.P.
Unit Majority will be required with respect to the following actions involving
the Partnership: (i) the material amendment, modification or termination of the
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
Partnership; (iii) the institution of any proceeding for bankruptcy of the
Partnership; (iv) the Transfer of any General Partnership Interests, including


<PAGE>


transfers attendant to any merger, consolidation or liquidation of the Company
except as otherwise provided in 11.2C; (v) the admission of any additional or
substitute General Partner in the Partnership; and (vi) a Change of Control
Transaction. In addition, until the Protective Provisions Expiration Date, the
consent of the L.P. Unit Majority will also be required with respect to: (i) any
Terminating Capital Transaction; (ii) the dissolution and liquidation of the
Partnership; and (iii) the Partnership's issuance of Limited Partner Interests
having seniority over the L.P. Units with respect to distributing assets, and
voting rights.

     8.10 APPROVAL OF CERTAIN TAXABLE SALES. Until the earlier of the tenth
anniversary of the closing of the Berg Acquisition and the Protective Provisions
Expiration Date, the General Partner must obtain the prior written consent of
Carl E. Berg, and upon Carl Berg's death if prior to the expiration of this
provision, Clyde J. Berg, before effecting any sale or other transfer of any of
the Properties identified on Schedules 1, 2, 3 or 5 to the Acquisition Agreement
on behalf of the Partnership which results in the recognition of taxable income
by any member of the Berg Group under the Code. Until the earlier of the tenth
anniversary of the Berg Acquisition and the date on which John T. Kontrabecki
ceases to beneficially own at least 750,000 L.P. Units, the General Partner
shall obtain his prior written consent prior to effecting any sale or other
transfer of any of the Properties (identified in Schedules 4 or 5 to the
Acquisition Agreement) as owned by Kontrabecki, Triangle Partners, or Berg
Ventures II, which will result in the recognition of taxable income by
Kontrabecki under the Code.

ARTICLE 9. BOOKS, RECORDS, ACCOUNTING AND REPORTS.

     9.1 RECORDS AND ACCOUNTING. The General Partner shall keep or cause to be
kept at the principal office of the Partnership those records and documents
required to be maintained by the Act and other books and records deemed by the
General Partner to be appropriate with respect to the Partnership's business,
including, without limitation, all books and records necessary to comply with
applicable REIT Requirements and to provide to the Limited Partners any
information, lists and copies of documents required to be provided pursuant to
Sections 8.5A and 9.3 hereof. Any records maintained by or on behalf of the
Partnership in the regular course of its business may be kept on, or be in the
form of, punch cards, magnetic tape, photographs, micrographics or any other
information storage device, provided that the records so maintained are
convertible into clearly legible written form within a reasonable period of
time. The books of the Partnership shall be maintained, for financial and tax
reporting purposes, on an accrual basis in accordance with GAAP, or such other
basis as the General Partner determines to be necessary or appropriate.

     9.2 FISCAL YEAR. The fiscal year of the Partnership shall be the calendar
year.

ARTICLE 10. TAX MATTERS.

     10.1 PREPARATION OF TAX RETURNS. The General Partner shall arrange for the
preparation and timely filing of all Partnership returns for federal and state
income tax purposes and shall use all reasonable efforts to furnish, within
sixty (60) days of the close of each taxable year, the tax information
reasonably required by Limited Partners for their federal and state income tax
reporting purposes.

     10.2 TAX ELECTIONS. The General Partner shall elect for the Partnership to


<PAGE>


be considered a limited partnership on all applicable federal and state income
tax returns to be filed by the Partnership. Except as otherwise provided herein,
the General Partner shall, in its sole and absolute discretion, determine
whether to make any other  available  election  pursuant  to the Code.
Notwithstanding the above, in making any such tax election the General Partner
shall take into account the tax consequences to the Limited Partners resulting
from any such election. The General Partner shall make such tax elections on
behalf of the Partnership as the L.P. Unit Majority request, provided that the
General Partner believes that such election is not adverse to the interests of
the General Partner, including its interest in preserving its qualification as a
REIT under the Code. In addition, the General Partner shall elect the
"traditional  method" of making Section 704(c)  allocations  pursuant to
Regulations Section 1.704-3 with respect to each Property under the Acquisition
Agreement. The General Partner shall have the right to seek to revoke any tax
election it makes (other than the election to use the traditional method of
making the Section 704(c) allocations  described in this Section 10.2),
including, without limitation, the election under Section 754 of the Code, upon
the General Partner' s determination, in its sole and absolute discretion, that
such revocation is in the best interests of the Limited Partners taken as a
whole and with the approval of the L.P. Unit Majority until the Protective
Provisions Expiration Date. All such elections and determinations may be made on
a Property-by-Property basis, and the General Partner shall be required to
analyze the impact of all such elections and determinations on that basis.

     10.3 TAX MATTERS PARTNER.

     A. The General Partner shall be the "tax matters partner" of the
Partnership for federal income tax purposes. Pursuant to Section 6230(e) of the
Code, upon receipt of notice from the Internal Revenue Service of the beginning
of an administrative proceeding with respect to the Partnership, the tax matters
partner shall furnish the Internal Revenue Service with the name, address,
taxpayer identification number, and Percentage Interest of each of the Limited
Partners and the Assignees; provided, that such information is provided to the
Partnership by the Limited Partners and the Assignees.

     B. The tax matters partner is authorized, but not required:

          (1) to enter into any settlement with the Internal Revenue Service
     with respect to any administrative or judicial proceedings for the
     adjustment of Partnership items required to be taken into account by a
     Partner for income tax purposes (such administrative proceedings being
     referred to as a "tax audit" and such judicial proceedings being referred
     to as "judicial review"), and in the settlement agreement the tax matters
     partner may expressly state that such agreement shall bind all Partners,
     except that such settlement agreement shall not bind any Partner (i) who
     (within the time prescribed pursuant to the Code and Regulations) files a
     statement with the Internal Revenue Service providing that the tax matters
     partner shall not have the authority to enter into a settlement agreement
     on behalf of such Partner; or (ii) who is a "notice partner" (as defined in
     Section 6231(a)(8) of the Code) or a member of a "notice group" (as defined
     in Section 6223(b)(2) of the Code);

          (2) in the event that a notice of a final administrative adjustment at
     the Partnership level of any item required to be taken into account by a
     Partner for tax purposes (a "final adjustment") is mailed to the tax
     matters partner, to seek judicial review of such final adjustment,
     including the filing of a petition for readjustment with the Tax Court or


<PAGE>


     the filing of a complaint for refund with the United States Claims Court or
     the District Court of the United States for the district in which the
     Partnership's principal place of business is located;

          (3) to intervene in any action brought by any other Partner for
     judicial review of a final adjustment;

          (4) to file a request for an administrative adjustment with the
     Internal Revenue Service and, if any part of such request is not allowed by
     the Internal Revenue Service, to file an appropriate pleading (petition or
     complaint) for judicial review with respect to such request;

          (5) to enter into an agreement with the Internal Revenue Service to
     extend the period for assessing any tax which is attributable to any item
     required to be taken account of by a Partner for tax purposes, or an item
     affected by such item; and

          (6) to take any other action on behalf of the Partners or the
     Partnership in connection with any tax audit or judicial review  proceeding
     to the extent permitted by applicable law or regulations.

     The taking of any action and the incurring of any expense by the tax
     matters partner in connection with any such proceeding, except to the
     extent required by law, is a matter in the sole and absolute discretion of
     the tax matters partner and the provisions relating to indemnification of
     the General Partner set forth in Section 7.6 of this Agreement shall be
     fully applicable to the tax matters partner in its capacity as such.

     C. The tax matters partner shall receive no compensation for its services.
All third party costs and expenses incurred by the tax matters partner in
performing its duties as such (including legal and accounting fees and expenses)
shall be borne by the Partnership. Nothing herein shall be construed to restrict
the Partnership from engaging an accounting firm to assist the tax matters
partner in discharging its duties hereunder, so long as the compensation paid by
the Partnership for such services is reasonable.

     10.4 ORGANIZATIONAL EXPENSES. The Partnership shall elect to deduct
expenses, if any, incurred by it in organizing the Partnership ratably over a
60-month period as provided in Section 709 of the Code.

     10.5 WITHHOLDING. Each Limited Partner hereby authorizes the Partnership to
withhold from, or pay on behalf of or with respect to, such Limited Partner any
amount of federal, state, local, or foreign taxes that the General Partner
determines that the Partnership is required to withhold or pay with respect to
any amount distributable or allocable to such Limited Partner pursuant to this
Agreement, including, without limitation, any taxes required to be withheld or
paid by the Partnership pursuant to Sections 1441, 1442, 1445, or 1446 of the
Code. Any amount paid on behalf of or with respect to a Limited Partner shall
constitute a loan by the Partnership to such Limited Partner, which loan shall
be repaid by such Limited Partner within 15 days after notice from the General
Partner that such payment must be made unless (i) the Partnership withholds such
payment from a distribution which would otherwise be made to the Limited
Partner; or (ii) the General Partner determines, in its sole and absolute
discretion, that such payment may be satisfied out of the amount of Available
Cash which would, but for such payment, be distributed to the Limited Partner.
Any amounts withheld pursuant to the foregoing clauses (i) or (ii) shall be
treated as having been distributed to such Limited Partner. Each Limited Partner


<PAGE>


hereby unconditionally and irrevocably grants to the Partnership a security
interest in such Limited Partner's Partnership Interest to secure such Limited
Partner's obligation to pay to the Partnership any amounts required to be paid
pursuant to this Section 10.5. In the event that a Limited Partner fails to pay
when due any amounts owed to the Partnership pursuant to this Section 10.5, the
General Partner may, in its sole and absolute discretion, elect to make the
payment to the Partnership on behalf of such defaulting Limited Partner, and in
such event shall be deemed to have loaned such amount to such defaulting Limited
Partner and shall succeed to all rights and remedies of the Partnership as
against such defaulting Limited Partner. Without limitation, in such event, the
General Partner shall have the right to receive distributions that would
otherwise be distributable to such defaulting Limited Partner until such time as
such loan, together with all interest thereon, has been paid in full, and any
such distributions so received by the General Partner shall be treated as having
been distributed to the defaulting Limited Partner and immediately paid by the
defaulting Limited Partner to the General Partner in repayment of such loan. Any
amount payable by a Limited Partner hereunder shall bear interest at the highest
base or prime rate of interest published from time to time by any of Wells Fargo
Bank, N.A., plus 4 percentage points, but in no event higher than the maximum
lawful rate of interest on such obligation, such interest to accrue from the
date such amount is due (i.e., 15 days after demand) until such amount is paid
in full. Each Limited Partner shall take such actions as the Partnership or the
General Partner shall request in order to perfect or enforce the security
interest created hereunder.

ARTICLE 11. TRANSFERS AND WITHDRAWALS.

     11.1 TRANSFER.

     A. The term "Transfer," when used in this Article 11 with respect to a
Unit, shall be deemed to refer to a transaction by which the General Partner
purports to assign all or any part of its General Partner Interest to another
Person or by which a Limited Partner purports to assign all or any part of its
Limited Partner Interest to another Person. The term "Transfer" when used in
this Article 11 does not include any exchange of L.P. Units for shares of Common
Stock pursuant to the Exchange Rights Agreement.

     B. No Partnership Interest shall be Transferred, in whole or in part,
except in accordance with the terms and conditions set forth in this Article 11.
Any Transfer or purported Transfer of a Partnership Interest not made in
accordance with this Article 11 shall be null and void.

     11.2 TRANSFER OF THE COMPANY'S PARTNERSHIP INTERESTS.

     A. The General Partner may not withdraw as General Partner or transfer its
General Partner Interest or Limited Partner Interest unless (i) the L.P. Unit
Majority (excluding L.P. Units held by the Company) consents to such Transfer or
withdrawal, or (ii) such Transfer is to an entity which is wholly-owned by the
Company and is a Qualified REIT Subsidiary under Section 856(i) of the Code.

     B. In the event the General Partner withdraws as General Partner in
accordance with Section 11.2A, the General Partner's General Partner Interest
shall immediately be converted into a Limited Partner Interest.

     11.3 LIMITED PARTNERS' RIGHTS TO TRANSFER.

     A. Subject to the provisions of this Section 11.3, a Limited Partner (other


<PAGE>


than the Company) may, without the consent of the General Partner:

          (a) if such Limited Partner is a partnership or a limited liability
     company, Transfer such Limited Partner's L.P. Units to any partner of such
     Limited Partner or any member of such limited liability company;

          (b) Transfer such Limited  Partner's L.P. Units to any other Limited
     Partner; and

          (c)  pledge such Limited Partner's L.P. Units to any financial
     institution as collateral for any loan with respect to which such Limited
     Partner is personally liable.

     B. Subject to the provisions of this Section 11.3, a Limited Partner may
Transfer any of such Limited Partner's L.P. Units, other than in accordance with
Section 11.3A, only with the prior written consent of the General Partner which
may be withheld in its sole discretion.

     C. If a Limited  Partner is subject to Incapacity,  the executor,
administrator, trustee, committee, guardian, conservator or receiver of such
Limited Partner's estate shall have all of the rights of a Limited Partner, but
not more rights than those enjoyed by other Limited Partners, for the purpose of
settling or managing the estate and such power as the Incapacitated Limited
Partner possessed to Transfer all or any part of his or its interest in the
Partnership. The Incapacity of a Limited Partner, in and of itself, shall not
dissolve or terminate the Partnership.

     D. No Transfer by a Limited Partner of its L.P. Units may be made to any
Person if (i) in the opinion of legal counsel for the Partnership, it would
result in the Partnership being treated as an association taxable as a
corporation; (ii) such Transfer would cause the Partnership to become, with
respect to any Employee  Benefit Plan subject to Title I of ERISA, a
"party-in-interest" (as defined in Section 3(14) of ERISA) or a "disqualified
person" (as defined in Section 4975(c) of the Code); (iii) such Transfer would,
in the opinion of legal counsel for the Partnership, cause any portion of the
assets of the Partnership to constitute assets of any Employee Benefit Plan
pursuant to Department of Labor Regulations Section 2510.2-101; (iv) such
Transfer would subject the Partnership to regulation under the Investment
Company Act of 1940, the Investment Advisors Act of 1940 or ERISA; or (v) such
Transfer is a sale or exchange, and such sale or exchange would, when aggregated
with all other sales and exchanges during the 12-month period ending on the date
of the proposed Transfer, result in a Change of Control Transaction.

     E. Subject to the foregoing provisions of Section 11.3 and the terms of
Section 12.2, a Limited Partner may transfer L.P. Units to an Affiliate and have
such Affiliate become a Limited Partner.

     In addition to the conditions set forth in Sections 11.3D, 11.4, and 12.2
any Transfer pursuant to this Article 11 is subject to the following conditions:

               (1) unless such Transfer is being made pursuant to an effective
          registration statement under the Securities Act, or pursuant to Rule
          144 or Rule 144A thereunder, the transferring Limited Partner shall
          deliver to the Company a notice with respect to the proposed transfer,
          together with an opinion of counsel in form and substance satisfactory
          to the General Partner prepared by counsel reasonably satisfactory to
          the General Partner (which shall include, without limitation, counsel


<PAGE>


          to each of the Limited Partners as of the date hereof), to the effect
          that an exemption from registration and qualification under such
          Securities Act is available;

               (2) the transferring Limited Partner and its transferee shall
          each provide a certificate to the General Partner, in form and
          substance satisfactory to the General Partner, to the effect that (i)
          the proposed transfer will not be effected on or through (a) a United
          States national, regional or local securities exchange, (b) a foreign
          securities exchange or (c) an interdealer quotation system that
          regularly disseminates firm buy or sell quotations by identified
          brokers or dealers (including, without limitation, the Nasdaq) by
          electronic means or otherwise, and (ii) it is not, and the proposed
          transfer will not be made by, through or on behalf of, (a) a Person
          who regularly quotes equity interests in the Partnership, such as a
          broker or dealer making a market in equity  interests in the
          Partnership or (b) a Person who regularly makes available to the
          public (including customers or subscribers) bid or offer quotes with
          respect to equity interests in the Partnership and stands ready to
          effect buy or sell transactions at the quoted prices for itself or on
          behalf of others; PROVIDED, HOWEVER, that such certificate shall not
          be required for any transfer in connection with a registered public
          offering;

               (3) the  transferee must be a United States Person for federal
          income tax purposes; and

               (4) such transfer must not cause the  Partnership to terminate or
          lose its status as a partnership for tax purposes.

     F. If it shall become unlawful for any Limited Partner to continue to hold
some or all of the L.P. Units held by such Limited Partner, or by reason of
legal or regulatory restrictions the cost to such Limited Partner to continue to
hold such L.P. Units (in relation to the value of such L.P. Units to such
Limited Partner) has, in the reasonable judgment of such Limited Partner,
significantly increased, such Limited Partner may, at any time following the
date three business days after the delivery by such Limited Partner to the
General Partner a notice of the existence of any such restriction, Transfer all
or any portion of the L.P. Units held by such Limited Partner free of any
restrictions imposed under this Agreement (other than those restrictions
required by federal or state laws, including securities, and tax, laws, and
subject to the prospective transferee meeting the requirements of Section 12.2,
and provided that the transferee Limited Partner shall hold its L.P. Units
subject to all of the terms of this Agreement); but only if such Limited Partner
cannot then exercise its Exchange Rights or Put Rights for cash, and the Company
has notified the Limited Partner that the Company will not register for offer
and sale all shares of Common Stock issued upon the exercise of the Exchange
Rights within 90 days. In connection therewith, the Company shall assist such
Limited Partner in disposing of the L.P. Units held by it in a prompt and
orderly manner, and (at the request of such Limited Partner) make available (and
authorize such Limited Partner to make available through the Company) financial
and other information concerning the Company and its Subsidiaries (including,
without limitation, the information described in Rule 144A(d)(4)) to any
prospective purchaser of such L.P. Units (it being agreed that such prospective
purchaser shall be either an "accredited investor" within the meaning of Rule
501 (a) under the Securities Act or a "qualified institutional buyer" within the
meaning of Rule 144A(d)(1) under such Act to the extent that such L.P. Units are


<PAGE>


"restricted securities" as such term is defined in Rule 144). The Company may
require that each such prospective purchaser keep confidential, pursuant to
customary confidentiality requirements, any information received by it pursuant
to this provision.

     11.4 SUBSTITUTED LIMITED PARTNERS. The General Partner shall have the right
to consent to the admission of a transferee who receives L.P. Units pursuant to
Section 11.3A, C, or E, which consent may be given or withheld by the General
Partner in its sole and absolute discretion. The General Partner's failure or
refusal to permit such transferee to become a Substituted Limited Partner shall
not give rise to any cause of action against the Partnership or any Partner.

     11.5 ASSIGNEES.  If the General Partner, in its sole and absolute
discretion, does not consent to the admission of any transferee as a Substituted
Limited Partner, as described in Section 11.4, such transferee shall be
considered an Assignee for purposes of this Agreement. An Assignee shall be
deemed to have had  assigned to it, and shall be entitled to receive
distributions from the Partnership and the share of Net Income, Net Losses and
any other Tax Items with respect to the L.P. Units assigned to such transferee,
but shall not be deemed to be a holder of L.P. Units for any other purpose under
this Agreement, and shall not be entitled to vote such L.P. Units in any matter
presented to the Limited Partners for a vote (such L.P. Units being deemed to
have been voted on such matter in the same proportion as all other L.P. Units
held by Limited Partners are voted). In the event the Assignee desires to make a
further assignment of any such L.P. Units, such Assignee shall be subject to all
of the provisions of this Article 11 to the same extent and in the same manner
as any Limited Partner desiring to make an assignment of L.P. Units.

     11.6 EFFECT OF PROHIBITED TRANSFER. Any transfer made in violation of
Article 11 shall be null and void and of no force and effect.

     11.7 GENERAL PROVISIONS.

     A. No Limited Partner may withdraw from the Partnership other than as a
result of a permitted Transfer of all of such Limited Partner's L.P. Units in
accordance with this Article 11, or pursuant to the tender or exchange of all of
its L.P. Units pursuant to the exercise of Put Rights or Exchange Rights.

     B. Any Limited Partner who shall Transfer all of its L.P. Units in a
Transfer permitted pursuant to this Article 11 shall cease to be a Limited
Partner upon the admission of all Assignees of such L.P. Units as Substituted
Limited Partners. Similarly, any Limited Partner who shall Transfer all of its
L.P. Units pursuant to a tender or exchange of all of its L.P. Units pursuant to
the exercise of Put Rights or Exchange Rights shall cease to be a Limited
Partner.

     C. Without the consent of the General Partner, permitted Transfers pursuant
to this Article 11 may be made effective only as of the first day of a Quarter.

     D. If any Partnership Interest is transferred or assigned during the year
in compliance with the provisions of this Article 11, or redeemed pursuant to
Section 8.7, or exchanged pursuant to the Exchange Rights Agreement on any day
other than the first day of a Partnership Year, the Net Income, Net Losses, each
item thereof, and all other Tax Items attributable to such interest for such
Partnership Year shall be divided and allocated between the transferor Partner
and the transferee Partner by taking into account their varying interests during
the Partnership Year in accordance with Section 706(d) of the Code, using the


<PAGE>


interim closing of the books method. Solely for purposes of making such
allocations, each of such items for the calendar month in which the Transfer or
assignment occurs shall be allocated to the transferee Partner, and none of such
items for the calendar month in which an exchange occurs shall be allocated to
the exchanging Partner, provided, however, that the General Partner may adopt
such other conventions relating to allocations in connection with transfers,
assignments, or exchanges as it determines are necessary or appropriate. All
distributions of Available Cash attributable to such L.P. Units with respect to
which the Partnership Record Date is before the date of such transfer,
assignment, or exchange shall be made to the transferor Partner or the
exchanging Partner, as the case may be, and in the case of a Transfer or
assignment other than an exchange, all distributions of Available Cash
thereafter attributable to such L.P. Units shall be made to the transferee
Partner.

ARTICLE 12. ADMISSION OF PARTNERS.

     12.1 ADMISSION OF SUCCESSOR GENERAL PARTNER. A successor to all of the
General Partner Interest pursuant to Article 11 hereof who is proposed to be
admitted as a successor General Partner shall be admitted to the Partnership as
the General Partner, effective upon the Transfer. Any such transferee shall
carry on the business of the Partnership without dissolution. In each case, the
admission shall be subject to the successor General Partner executing and
delivering to the Partnership an acceptance of all of the terms and conditions
of this Agreement, the Acquisition Agreement, and such other documents or
instruments as may be required to effect the admission. In the case of such
admission on any day other than the first day of a Partnership Year, all items
attributable to the General Partner Interest for such Partnership Year shall be
allocated between the transferring General Partner and such successor as
provided in Section 11.6D.

     12.2 ADMISSION OF ADDITIONAL AND SUBSTITUTED LIMITED PARTNERS.

     A. A Person who makes a Capital Contribution to the Partnership in
accordance with this Agreement after the Effective Date and a Permitted
Transferee pursuant to Article 11 shall be admitted to the Partnership as an
Additional Limited Partner or a Substituted Limited Partner only upon furnishing
to the General Partner (i) evidence of acceptance in form satisfactory to the
General Partner of all of the terms and conditions of this Agreement and the
Acquisition Agreement, including, without limitation, the power of attorney
granted in Section 2.4 hereof and (ii) such other documents or instruments as
may be required in the discretion of the General Partner in order to effect such
Person's admission as an Additional Limited Partner.

     B. Notwithstanding anything to the contrary in this Section 12.2, no Person
shall be admitted as an Additional Limited Partner or a Substituted Limited
Partner without the consent of the General Partner, which consent may be given
or withheld in the General Partner's sole and absolute discretion. The admission
of any Person as an Additional Limited Partner or a Substituted Limited Partner
shall become effective on the date upon which the name of such Person is
recorded on the books and records of the Partnership, following the consent of
the General Partner to such admission.

     C. If any Additional Limited Partner is admitted to the Partnership on any
day other than the first day of a Partnership Year, then Net Income, Net Losses,
each other Tax Item and all other items allocable among Partners and Assignees
for such Partnership Year shall be allocated among such Additional Limited


<PAGE>


Partner and all other Partners and Assignees by taking into account their
varying interests during the Partnership Year in accordance with Section 706(d)
of the Code, using the interim closing of the books method. Solely for purposes
of making such allocations, each of such items for the calendar month in which
an admission of any Additional Limited Partner occurs shall be allocated among
all of the Partners and Assignees, including such Additional Limited Partner.
All distributions of Available Cash with respect to which the Partnership Record
Date is before the date of such admission shall be made solely to Partners and
Assignees, other than the Additional Limited Partner, and all distributions of
Available Cash thereafter shall be made to all of the Partners and Assignees,
including such Additional Limited Partner.

     D. A transferee who has been admitted as a Substituted Limited Partner or
an Additional Limited Partner shall have all the rights and powers and be
subject to all the restrictions and liabilities of a Limited Partner under this
Agreement.

     12.3 AMENDMENT OF AGREEMENT AND CERTIFICATE OF LIMITED PARTNERSHIP. For the
admission to the Partnership of any Partner, the General Partner shall take all
steps necessary and appropriate under the Act to amend the records of the
Partnership and, if necessary, to prepare as soon as practical an amendment of
this Agreement (including an amendment of Appendix I) and, if required by law,
shall prepare and file an amendment to the Certificate and may for this purpose
exercise the power of attorney granted pursuant to Section 2.4 hereof.

ARTICLE 13. DISSOLUTION, LIQUIDATION AND TERMINATION.

     13.1 DISSOLUTION. The Partnership shall not be dissolved by the admission
of Substituted Limited Partners or Additional Limited Partners or by the
admission of a successor General Partner in accordance with the terms of this
Agreement. In the event of the withdrawal of the General Partner, any successor
General Partner shall continue the business of the Partnership. The Partnership
shall dissolve, and its affairs shall be wound up, only upon the first to occur
of any of the following ("Liquidating Events"):

          (i) the expiration of its term as provided in Section 2.5 hereof;

          (ii) an event of withdrawal of the General Partner, as defined in the
     Act (other than an event of bankruptcy), unless, within 90 days after such
     event of withdrawal a majority in interest of the remaining Partners agree
     in writing to continue the business of the Partnership and to the
     appointment, effective as of the date of withdrawal, of a successor General
     Partner;

          (iii) from and after the date of this Agreement through December 31,
     2048, an election to dissolve the Partnership made by the General Partner,
     with the Consent of Limited Partners holding 66-2/3% or more of the L.P.
     Units (including L.P. Units held by the Company);

          (iv) on or after January 1, 2049, an election to dissolve the
     Partnership made by the General Partner, in its sole and absolute
     discretion;

          (v)  entry of a decree of judicial dissolution of the Partnership
     pursuant to the provisions of the Act;

          (vi) the sale of all or substantially all of the assets and properties


<PAGE>


     of the Partnership;

          (vii) a final and non-appealable judgment is entered by a court of
     competent jurisdiction ruling that the General Partner is bankrupt or
     insolvent, or a final and non-appealable order for relief is entered by a
     court with appropriate jurisdiction against the General Partner, in each
     case under any federal or state bankruptcy or insolvency laws as now or
     hereafter in effect, unless prior to the entry of such order or judgment
     all of the remaining Partners agree in writing to continue the business of
     the Partnership and to the appointment, effective as of a date prior to the
     date of such order or judgment, of a substitute General Partner.

     13.2 WINDING UP.

     A. Upon the occurrence of a Liquidating Event, the Partnership shall
continue solely for the purposes of winding up its affairs in an orderly manner,
liquidating its assets, and satisfying the claims of its creditors and Partners.
No Partner shall take any action that is inconsistent with, or not necessary to
or appropriate for, the winding up of the Partnership's business and affairs.
The General Partner, or, in the event there is no remaining General Partner, any
Person elected by Limited Partners holding at least a majority of the Limited
Partnership Interests (the General Partner or such other Person being referred
to herein as the "Liquidator"), shall be responsible for overseeing the winding
up and dissolution of the Partnership and shall take full account of the
Partnership's liabilities and property and the Partnership property shall be
liquidated as promptly as is consistent with obtaining the fair value thereof,
and the proceeds therefrom (which may, to the extent determined by the General
Partner, include shares of beneficial interest or other securities of the
Company) shall be applied and distributed in the following order:

          (i) First, to the payment and discharge of all of the Partnership's
     debts and liabilities to creditors other than the Partners;

          (ii) Second, to the payment and discharge of all of the Partnership's
     debts and liabilities to the General Partner;

          (iii) Third, to the payment and discharge of all of the  Partnership's
     debts and liabilities to the other Partners;

          (iv) Fourth, to the General Partner and Limited Partners to the extent
     of and in accordance with the positive balances in their Capital Accounts,
     after giving effect to all contributions, distributions, and allocations
     for all periods; and

          (v) The balance, if any, to the Partners according to their Percentage
     Interests.

The  General Partner shall not receive any additional compensation for any 
services performed pursuant to this Article 13.

     B.  Notwithstanding the provisions of Section 13.2A hereof which require
liquidation of the assets of the Partnership, but subject to the order of
priorities set forth therein, if prior to or upon dissolution of the Partnership
the Liquidator determines that an immediate sale of part or all of the
Partnership's assets would be impractical or would cause undue loss to the
Partners, the Liquidator may, in its sole and absolute discretion, defer for a
reasonable time the liquidation of any asset except those necessary to satisfy


<PAGE>


liabilities of the Partnership (including to those Partners as creditors) and/or
distribute to the Partners, in lieu of cash, as tenants in common and in
accordance with the provisions of Section 13.2A hereof, undivided interests in
such Partnership assets as the Liquidator deems not suitable for liquidation.
Any such distributions in kind shall be made only if, in the good faith judgment
of the Liquidator, such distributions in kind are in the best interests of the
Partners, and shall be subject to such conditions relating to the disposition
and management of such properties as the Liquidator deems reasonable and
equitable and to any agreements governing the operation of such properties at
such time. The Liquidator shall determine the fair market value of any property
distributed in kind using such reasonable method of valuation as it may adopt.

     C.  In the discretion of the Liquidator, a pro rata portion of the
distributions that would otherwise be made to the General Partner and Limited
Partners pursuant to this Article 13 may be:

          (1) distributed to a trust established for the benefit of the General
     Partner and Limited Partners for the purposes of liquidating Partnership
     assets, collecting amounts owed to the Partnership, and paying any
     contingent or unforeseen liabilities or obligations of the Partnership or
     the General Partner arising out of or in connection with the Partnership.
     The assets of any such trust shall be distributed to the General Partner
     and Limited Partners from time to time, in the reasonable discretion of the
     Liquidator, in the same proportions as the amount distributed to such trust
     by the Partnership would otherwise have been distributed to the General
     Partner and Limited Partners pursuant to this Agreement; or

          (2)  withheld  or  escrowed  to  provide  a  reasonable   reserve  for
     Partnership  liabilities  (contingent  or  otherwise)  and to  reflect  the
     unrealized portion of any installment  obligations owed to the Partnership,
     provided that such withheld or escrowed amounts shall be distributed to the
     General  Partner and  Limited  Partners in the manner and order of priority
     set forth in Section 13.2A as soon as practicable.

     13.3  OBLIGATION TO CONTRIBUTE DEFICIT. In the event the Partnership is
"liquidated" within the meaning Section 1.704-1(b)(2)(ii)(G) of the Regulations,
if any Partner's Adjusted Contributions are less than zero (after giving effect
to all contributions, distributions, and allocations for all Fiscal Years,
including the Fiscal Year during which such liquidation occurs), such Partner
shall contribute to the capital of the Partnership the amount necessary to
restore such Partner's Capital Account to zero in compliance with Regulations
Section 1.704-1(b)(2(ii)(B)(3).

     13.4  RIGHTS OF LIMITED PARTNERS. Except as otherwise provided in this
Agreement, each Limited Partner shall look solely to the assets of the
Partnership for the return of its Adjusted Capital Contributions and shall have
no right or power to demand or receive property other than cash from the
Partnership. Except as otherwise provided in this Agreement, no Limited Partner
shall have priority over any other Partner as to the return of its Adjusted
Capital Contributions, distributions, or allocations.

     13.5 NOTICE OF DISSOLUTION. In the event a Liquidating Event occurs or an
event occurs that would, but for the provisions of an election or objection by
one or more Partners pursuant to Section 13.1, result in a dissolution of the
Partnership, the General Partner shall, within 30 days thereafter, provide
written notice thereof to each of the Partners.


<PAGE>


     13.6  TERMINATION OF PARTNERSHIP AND CANCELLATION OF CERTIFICATE OF LIMITED
PARTNERSHIP. Upon the completion of the liquidation of the Partnership' s
assets, as provided in Section 13.2 hereof, the Partnership shall be terminated,
a certificate of cancellation shall be filed, and all qualifications of the
Partnership as a foreign limited partnership in jurisdictions other than the
state of Delaware shall be canceled and such other actions as may be necessary
to terminate the Partnership shall be taken.

     13.7 REASONABLE TIME FOR WINDING-UP. A reasonable time shall be allowed for
the orderly winding-up of the business and affairs of the Partnership and the
liquidation of its assets pursuant to Section 13.2 hereof in order to minimize
any losses otherwise attendant upon such winding-up, and the provisions of this
Agreement shall remain in effect among the Partners during the period of
liquidation.

     13.8 WAIVER OF PARTITION. Each Partner hereby waives any right to partition
of the Partnership property.

     13.9 DEEMED DISTRIBUTION AND RECONTRIBUTION. Notwithstanding any other
provisions of this Article 13, in the event the Partnership is liquidated within
the meaning of Regulations Section 1.704-1(b)(2)(ii)(G) but no Liquidating Event
has occurred,  the Property shall not be liquidated,  the Partnership's
liabilities shall not be paid or discharged, and the Partnership's affairs shall
not be wound up. Instead, the Partnership shall be deemed to have distributed
the Property in kind to the Partners, who shall be deemed to have assumed and
taken subject to all Partnership liabilities, all in accordance with their
respective Capital Accounts, and if any Partner has an Adjusted Capital Account
Deficit (after giving effect to all  contributions,  distributions,  and
allocations for all Fiscal Years, including the Fiscal Year during which such
liquidation occurs) such Partner shall contribute to the capital of the
Partnership the amount necessary to restore such deficit balance to zero in
compliance with  Regulations  Section 1.704-1(b)(2(ii)(b)(3).  Immediately
thereafter, the Partners shall be deemed to have recontributed the property in
kind to the Partnership, which shall be deemed to have assumed and taken subject
to all such liabilities.

ARTICLE 14. AMENDMENT OF PARTNERSHIP AGREEMENT; MEETINGS.

     14.1 AMENDMENTS.

     A.  Amendments to this Agreement may be proposed by the General Partner or
by any Limited Partners (other than the Company) holding in the aggregate 25% or
more of the Partnership Interests. Following such proposal, the General Partner
shall submit any proposed amendment to the Limited Partners. The General Partner
shall seek the written vote of the Partners on the proposed amendment or shall
call a meeting to vote thereon and to transact any other business that it may
deem appropriate. For purposes of obtaining a written vote, the General Partner
may require a response within a reasonable specified time, but not less than 15
days, and failure to respond in such time period shall constitute a vote which
is consistent with the General Partner's recommendation with respect to the
proposal. Except as provided in Section 8.9, 13.1C, 14.1B, 14.1C or 14.1D, a
proposed amendment shall be adopted and be effective as an amendment hereto if
it is approved by the General Partner and it receives the Consent of Limited
Partners holding 50% or more of the Percentage Interests of the Limited Partners
(including Limited Partner Interests held by the Company).

     B.  Notwithstanding any provisions of Sections 8.9 and 14.1A to the


<PAGE>


contrary, the General Partner shall have the power, without the consent of the
Limited Partners, to amend this Agreement as may be required to facilitate or
implement any of the following purposes:

          (1) to add to the obligations of the General Partner or surrender any
     right or power granted to the General Partner or any Affiliate of the
     General Partner for the benefit of the Limited Partners;

          (2) to reflect the admission, substitution, termination, or withdrawal
     of Partners in accordance with this Agreement;

          (3) to set forth the designations, rights, powers, duties, and
     preferences of the holders of any additional Partnership Interests issued
     pursuant to Section 4.3 hereof;

          (4) to reflect a change that is of an inconsequential nature and does
     not adversely affect the Limited Partners in any material respect, or to
     cure any ambiguity, correct or supplement any provision in this Agreement
     not inconsistent with law or with other provisions, or make other changes
     with respect to matters arising under this Agreement that will not be
     inconsistent with law or with the provisions of this Agreement; and

          (5) to satisfy any requirements, conditions, or guidelines contained
     in any order, directive, opinion, ruling or regulation of a federal or
     state agency or contained in federal or state law.

The General Partner shall provide notice to the Limited Partners when any action
under this Section 14.1B is taken.

     C. Notwithstanding provision of Section 14.1A and 14.1B to the contrary,
this Agreement shall not be amended without the Consent of each Partner
adversely affected if such amendment would (i) convert a Limited Partner's
interest in the Partnership into a General Partner Interest; (ii) modify the
limited liability of a Limited Partner in a manner adverse to such Limited
Partner; (iii) alter rights of the Partner to receive distributions pursuant to
Article 5 or Article 13, or the allocations specified in Article 6 (except as
permitted pursuant to Article IV and Section 14.1B(3) hereof); (iv) cause the
termination of the Partnership prior to the time set forth in Section 2.5 or
13.1; or (v) amend this Section 14.1C. Further, no amendment may alter the
restrictions on the General Partner's authority set forth in Section 13.1C
without the Consent specified in that section.

     14.2 MEETINGS OF THE PARTNERS.

     A. Meetings of the Partners may be called by the General Partner and shall
be called upon the receipt by the General Partner of a written request by
Limited Partners (other than the Company) holding 25% or more of the Partnership
Interests. The request shall state the nature of the business to be transacted.
Notice of any such meeting shall be given to all Partners not less than 7 days
nor more than 30 days prior to the date of such meeting. Partners may vote in
person or by proxy at such meeting. Whenever the vote or Consent of the Limited
Partners is permitted or required under this Agreement, such vote or Consent may
be given at a meeting of the Partners or may be given in accordance with the
procedure prescribed in Section 14.1A hereof. Except as otherwise expressly
provided in this Agreement, the consent of holders of a majority of the
Percentage Interests held by Partners (including Limited Partnership Interests
held by the Company) shall control.


<PAGE>


     B. Any action required or permitted to be taken at a meeting of the
Partners may be taken without a meeting if a written consent setting forth the
action so taken is signed by a majority of the Percentage Interests of the
Partners (or such other percentage as is expressly required by this Agreement).
Such consent may be in one instrument or in several instruments, and shall have
the same force and effect as a vote of a majority of the Percentage Interests of
the Partners (or such other percentage as is expressly required by this
Agreement). Such consent shall be filed with the General Partner. An action so
taken shall be deemed to have been taken at a meeting held on the effective date
so certified.

     C. Each Limited Partner may authorize any Person or Persons to act for him
by proxy on all matters in which a Limited Partner is entitled to participate,
including waiving notice of any meeting, or voting or participating at a
meeting.  Every proxy must be signed by the Limited Partner or his
attorney-in-fact. No proxy shall be valid after the expiration of 11 months from
the date thereof unless otherwise provided in the proxy. Every proxy shall be
revocable at the pleasure of the Limited Partner executing it, such revocation
to be effective upon the Partnership's receipt of written notice of such
revocation from the Limited Partner executing such proxy.

     D. Each meeting of the Partners shall be conducted by the General Partner
or such other Person as the General Partner may appoint pursuant to such rules
for the conduct of the meeting as the General Partner or such other Person deems
appropriate. Meetings of Partners may be conducted in the same manner as
meetings of the shareholders of the Company and may be held at the same time,
and as part of, meetings of the shareholders of the Company.

                                   APPENDIX II



                      ALLOCATIONS OF PARTNERSHIP INTERESTS



1.    ALLOCATION OF NET INCOME AND NET LOSS.

      (a) NET INCOME. Except as otherwise provided in this Appendix II, Net
Income (or items thereof) (other than Net Income, or items thereof, arising in
connection with a Terminating Capital Transaction) for any fiscal year or other
applicable period shall be allocated to the Partners in accordance with their
respective Percentage Interests.

      (b) NET LOSS. Except as otherwise provided in this Appendix II, Net Loss
(or items thereof) of the Partnership for each fiscal year or other applicable
period shall be allocated to the Partners in accordance with the Partners'
respective Percentage Interests. Notwithstanding the preceding sentence, to the
extent any Net Loss (or items thereof) allocated to a Partner under this
subparagraph (b) would cause such Partner (hereinafter, a "Restricted Partner")
to have an Adjusted Capital Account Deficit, or increase the amount of an
existing Adjusted Capital Account Deficit, as of the end of the fiscal year or


<PAGE>


other applicable period to which such Net Loss relates, such Net Loss shall not
be allocated to such Restricted Partner and instead shall be allocated to the
other Partner(s) (hereinafter, the "Permitted Partners") pro rata in accordance
with each Permitted Partner's Percentage Interest.

      (c) TERMINATING CAPITAL TRANSACTION; LIQUIDATION. Allocations of Net
Income or Net Loss (or items thereof) in connection with a Terminating Capital
Transaction or Liquidation of the Partnership shall first be made so that, to
the extent possible, each Partner's Capital Account balance is equal to such
Partner's Adjusted Contribution, and the remainder of such Net Income or Net
Loss (or items thereof) shall be allocated to the Partners in accordance with
their Percentage Interests. Notwithstanding the preceding sentence, to the
extent any Net Loss (or items thereof) would be allocated to a Restricted
Partner under this subparagraph (c), such Net Loss shall not be allocated to
such Restricted Partner and instead shall be allocated to the Permitted Partners
pro rata in accordance with each Permitted Partner's Percentage Interest.

      (d)  RULES OF CONSTRUCTION.

           (1) CAPITAL ACCOUNT INCREASES. For purposes of making allocations
pursuant to subparagraph 1(c) of this Appendix II, a Partner's Capital Account
balance shall be deemed to be increased by such Partner's share of any
Partnership Minimum Gain and Partner Minimum Gain remaining at the close of the
fiscal period in respect of which such allocations are being made.

           (2) CHANGE IN PERCENTAGE INTERESTS. In the event any Partner's
Percentage Interest changes during a fiscal year for any reason, including
without limitation, the Transfer of any interest in the Partnership, the tax
allocations contained in this Appendix II shall be applied as necessary to
reflect the varying interests of the Partners during such year.

2.    SPECIAL ALLOCATIONS.

      Notwithstanding any provisions of paragraph 1 of this Appendix II, the
following special allocations shall be made.

      (a) MINIMUM GAIN CHARGEBACK (NONRECOURSE LIABILITIES). Except as otherwise
provided in Section 1.704-2(f) of the Regulations, if there is a net decrease in
Partnership Minimum Gain for any Partnership fiscal year, each Partner shall be
specially allocated items of Partnership income and gain for such year (and, if
necessary, subsequent years) in an amount equal to such Partner's share of the
net decrease in Partnership Minimum Gain to the extent required by Regulations
Section 1.704-2(f). The items to be so allocated shall be determined in
accordance with Sections 1.704-2(f) and (j)(2) of the Regulations. This
subparagraph 2(a) is intended to comply with the minimum gain chargeback
requirement in said Section of the Regulations and shall be interpreted
consistently therewith. Allocations pursuant to this subparagraph 2(a) shall be
made in proportion to the respective amounts required to be allocated to each
Partner pursuant hereto.

      (b) PARTNER MINIMUM GAIN CHARGEBACK. Except as otherwise provided in
Section 1.704-2(i)(4) of the Regulations, if there is a net decrease in Partner
Minimum Gain attributable to a Partner Nonrecourse Debt during any fiscal year,
each Partner who has a share of the Partner Minimum Gain attributable to such
Partner Nonrecourse Debt, determined in accordance with Section 1.704- 2(i)(5)
of the Regulations, shall be specially allocated items of Partnership income and
gain for such year (and, if necessary, subsequent years) in an amount equal to


<PAGE>


that Partner's share of the net decrease in the Partner Minimum Gain 
attributable to such Partner Nonrecourse Debt to the extent and in the manner 
required by Section 1.704-2(i) of the Regulations. The items to be so 
allocated shall be determined in accordance with Sections 1.704-2(i)(4) and 
(j)(2) of the Regulations. This subparagraph 2(b) is intended to comply with 
the minimum gain chargeback requirement with respect to Partner Nonrecourse 
Debt contained in said Section 1.704-2(i)(4) of the Regulations and shall be 
interpreted consistently therewith. Allocations pursuant to this subparagraph 
2(b) shall be made in proportion to the respective amounts required to be 
allocated to each Partner pursuant hereto.

      (c) QUALIFIED INCOME OFFSET. In the event a Partner unexpectedly 
receives any adjustments, allocations or distributions described in Sections 
1.704-1(b)(2)(ii)(d)(4), (5) or (6) of the Regulations, and such Partner has 
an Adjusted Capital Account Deficit, items of Partnership income (including 
gross income) and gain shall be specially allocated to such Partner in an 
amount and manner sufficient to eliminate the Adjusted Capital Account 
Deficit as quickly as possible as required by the Regulations. This 
subparagraph 2(c) is intended to constitute a "qualified income offset" under 
Section 1.704-1(b)(2)(ii)(d) of the Regulations and shall be interpreted 
consistently therewith.

      (d) OTHER CHARGEBACK OF IMPERMISSIBLE NEGATIVE CAPITAL ACCOUNT. To the
extent any Partner has an Adjusted Capital Account Deficit at the end of any
Partnership Year, each such Partner shall be specially allocated items of
Partnership income (including gross income) and gain in the amount of such
excess as quickly as possible, provided that an allocation pursuant to this
paragraph 2(d) shall be made if and only to the extent that such Partner would
have an Adjusted Capital Account Deficit after all other allocations provided
for in this Appendix II have been tentatively made as if this paragraph 2(d)
were not in the Agreement.

      (e) NONRECOURSE DEDUCTIONS. Nonrecourse Deductions for any fiscal year or
other applicable period shall be allocated to the Partners in accordance with
their respective Percentage Interests.

      (f) PARTNER NONRECOURSE DEDUCTIONS. Partner Nonrecourse Deductions for any
fiscal year or other applicable period with respect to a Partner Nonrecourse
Debt shall be specially allocated to the Partner that bears the economic risk of
loss for such Partner  Nonrecourse  Debt (as determined  under Sections
1.704-2(b)(4) and 1.704-2(i)(1) of the Regulations).

      (g) INTENT OF ALLOCATIONS. The parties intend that the allocation
provisions of this Appendix II shall result in final Capital Account balances of
the Partners that initially are equal to each Partner's Adjusted Contribution
and are then in proportion to the Partners' respective Percentage Interests, so
that when liquidating distributions are made in accordance with such final
Capital Account balances under Section 13.2A(4) hereof, such distributions will
be able to return to each Partner its Adjusted Contribution and then will be
made in proportion to the Partners' respective Percentage Interests. To the
extent that such final Capital Account balances do not so reflect the provisions
of this Appendix II, income and loss of the Partnership for the current year and
future years, as computed for book purposes, shall be allocated among the
Partners so as to result in final Capital Account balances reflecting the
provisions of this Appendix II, and to the extent such allocations of items of
income (including gross income) and deduction do not result in such final
Capital Account balances, then, income and loss of the Partnership for prior
open years, as computed for book purposes (or items of gross income and


<PAGE>


deduction of the Partnership for such years, as computed for book purposes)
shall be reallocated among the Partners consistent with the foregoing. This
subparagraph shall control notwithstanding any reallocation of income, loss, or
items thereof, as computed for book purposes, by the Internal Revenue Service or
any other taxing authority.

   (h) SECTION 754 ADJUSTMENT. To the extent an adjustment to the adjusted
tax basis of any asset of the Partnership pursuant to Section 734(b) of the Code
or Section 743(b) of the Code is required pursuant to Regulations Section
1.704-1(b)(2)(iv)(m) to be taken into account in determining Capital Accounts,
the amount of such adjustment to the Capital Accounts shall be treated as an
item of gain (if the adjustment increases the basis of the asset) or loss (if
the adjustment decreases such basis) and such gain or loss shall be specially
allocated among the Partners in a manner consistent with the manner in which
each of their respective Capital Accounts are required to be adjusted pursuant
to such section of the Regulations.

   (i) GROSS INCOME ALLOCATION. There shall be specially allocated to the
General Partner an amount of Partnership income and gain during each Partnership
Year or portion thereof, before any other allocations are made hereunder, which
is equal to the excess, if any, of the cumulative distributions of cash made to
the General Partner under Section 7.3B hereof over the cumulative allocations of
Partnership income and gain to the General Partner pursuant to this Section (i)
of this Appendix II.

3.    TAX ALLOCATIONS.

      (a) ITEMS OF INCOME OR LOSS. Except as is otherwise provided in this
Appendix II, an allocation of Partnership Net Income or Net Loss to a Partner
shall be treated as an allocation to such Partner of the same share of each item
of income, gain, loss, deduction and item of tax-exempt income or Section
705(a)(2)(B) expenditure (or item treated as such expenditure pursuant to
Regulations Section 1.704-1(b)(2)(iv)(i)) ("Tax Items") that is taken into
account in computing Net Income or Net Loss.

      (b) SECTION 1245/1250 RECAPTURE. If any portion of gain from the sale of
Partnership assets is treated as gain which is ordinary income by virtue of the
application of Code Sections 1245 or 1250 ("Affected Gain"), then such Affected
Gain shall be allocated among the Partners in the same proportion that the
depreciation and amortization deductions giving rise to the Affected Gain were
allocated. This subparagraph 3(b) shall not alter the amount of Net Income (or
items thereof) allocated among the Partners, but merely the character of such
Net Income (or items thereof). For purposes hereof, in order to determine the
proportionate allocations of depreciation and amortization deductions for each
fiscal year or other applicable period, such deductions shall be deemed
allocated on the same basis as Net Income and Net Loss for such respective
period.

      (c) PRECONTRIBUTION GAIN. The Partnership may elect the traditional method
of allocation contained in Section 1.704- 3(b) of the Regulations to take into
account any variation between the adjusted basis and the fair market value of
the  Initial  Contributed  Property  at the  time  of the  contribution
("Precontribution Gain") on a Property-by-Property basis. By executing this
Agreement, each Partner hereby agrees to report income, gain, loss and deduction
on such Partner's federal income tax return in a manner that is consistent with
the use of the traditional method of allocation with respect to the Initial
Contributed Property. With respect to any Contributed Property, the Partnership


<PAGE>


shall use any permissible method contained in the Regulations promulgated under
Section 704(c) of the Code selected by the General Partner, in its sole
discretion, to take into account any variation between the adjusted basis of
such asset and the fair market value of such asset as of the time of the
contribution. Each Partner hereby agrees to report income, gain, loss and
deduction on such Partner's federal income tax return in a manner consistent
with the method used by the Partnership.

      (d) ALLOCATIONS RESPECTING SECTION 704(C) AND Revaluations. If any asset
has a Gross Asset Value which is different from the Partnership's adjusted basis
for such asset for federal income tax purposes because the Partnership has
revalued such asset pursuant to Regulations Section 1.704-1(b)(2)(iv)(f), the
allocations of Tax Items shall be made in accordance with the principles of
Section 704(c) of the Code and the Regulations and the methods of allocation
promulgated thereunder, provided, however, that the General Partner shall elect
with respect to each Initial Contributed Property, to allocate the income, gain,
loss and deduction with respect to such Property using the "traditional method"
described in Regulations Section 1.704-3(b) unless the majority of the Limited
Partners affected thereby otherwise instruct the General Partner. The intent of
this Section 3(d) and Section 3(c) above is that each Partner who contributed to
the capital of the Partnership a Contributed Property will bear, through reduced
allocations of depreciation, increased allocations of gain or other items, the
tax detriments associated with any Precontribution Gain. This Section 3(d) and
Section 3(c) are to be interpreted consistently with such intent.

      (e) EXCESS NONRECOURSE LIABILITY SAFE HARBOR. Pursuant to Regulations
Section 1.752-3(a)(3), solely for purposes of determining each Partner's
proportionate share of the "excess nonrecourse liabilities" of the Partnership
(as defined in Regulations Section 1.752-3(a)(3)), the Partners' respective
interests in Partnership profits shall be determined in accordance with each
Partner's Percentage Interest; provided, however, that each Partner who has
contributed an asset to the Partnership shall be allocated, to the extent
possible, a share of "excess nonrecourse liabilities" of the Partnership which
results in such Partner being allocated nonrecourse liabilities in an amount
which is at least equal to the amount of income pursuant to Section 704(c) of
the Code and the Regulations promulgated thereunder (the "Liability Shortfall").
In the event there is an insufficient amount of nonrecourse liabilities to
allocate to each Partner an amount of nonrecourse liabilities equal to the
Liability Shortfall, then an amount of nonrecourse liabilities in proportion to,
and to the extent of, the Liability Shortfall shall be allocated to each
Partner.

      (f) REFERENCES TO REGULATIONS. Any reference in this Appendix II or the
Agreement to a provision of proposed and/or temporary Regulations shall, in the
event such provision is modified or renumbered, be deemed to refer to the
successor provision as so modified or renumbered, but only to the extent such
successor provision applies to the Partnership under the effective date rules
applicable to such successor provision.

      (g) SUCCESSOR PARTNERS. For purposes of this Appendix II, a transferee of
a Partnership Interest shall be deemed to have been allocated the Net Income,
Net Loss and other items of Partnership income, gain, loss, deduction and credit
allocable to the transferred Partnership Interest that previously have been
allocated to the transferor Partner pursuant to this Agreement.

      (h) LIMITATION TO PRESERVE REIT STATUS. Notwithstanding anything else in
this Agreement, to the extent that the amount paid, credited, distributed or


<PAGE>


reimbursed by the Partnership or any Partners to, for or with respect any
Partner that is a REIT ("REIT Partner") or its officers, directors, employees or
agents, whether as a reimbursement, fee, expense or indemnity (a "REIT
Payment"), would constitute gross income to the REIT Partner for purposes of
Section 856 (c)(2) or Section 856(c)(3) of the Code, then, notwithstanding any
other provision of this Agreement, the amount of such REIT Payments, as selected
by the General Partner in its discretion from among items of potential
distribution, reimbursement, fees, expenses and indemnities, shall be reduced
for any Fiscal Year so that the REIT Payments, as so reduced, to, for or with
respect to such REIT Partner shall not exceed the lesser of:

           (i) an amount equal to the excess, if any, of (x) four and
nine-tenths percent (4.9%) of the REIT Partner total gross income (but excluding
the amount of any REIT Payments) for the Fiscal Year that is described in
subSections (A) through (H) of Section 856(c)(2) over (y) the amount of gross
income (within the meaning of Section 856(c)(2)) derived by the REIT Partner
from sources other than those described in subSections (A) through (H) of
Section 856(c)(2) (but not including the amount of any REIT Payments); or

           (ii) an amount equal to the excess, if any, of (x) 24% of the REIT
Partner's total gross income (but excluding the amount of any REIT Payments) for
the Fiscal Year that is described in subSections (A) through (I) of Section
856(c)(3) over (y) the amount of gross income (within the meaning of Section
856(c)(3)) derived by the REIT Partner from sources other than those described
in subSections (A) through (I) of Section 856(c)(3) (but not including the
amount of any REIT Payments);

PROVIDED, HOWEVER, that REIT payments in excess of the amounts set forth in
clauses (i) and (ii) above may be made if the General Partner, as a condition
precedent, obtains an opinion of tax counsel that the receipt of such excess
amounts shall not adversely affect the REIT Partner's ability to qualify as a
REIT. To the extent that REIT Payments may not be made in a Fiscal Year as a
consequence of the limitations set forth in this Section 3(h), such REIT
Payments shall carry over and shall be treated as arising in the following
Fiscal Year. Nothing in this Section 3(h) shall permit the General Partner to
allocate income of the Partnership to any Partner in excess of the income that
would otherwise be allocated to it under Article 6 without regard to this
Section 3(h). The purpose of the limitations contained in this Section 3(h) is
to prevent any REIT Partner from failing to qualify as a REIT under the Code by
reason of such REIT Partner's share of items, including  distributions,
reimbursements, fees, expenses or indemnities, receivable directly or indirectly
from the Partnership or the Partners, and this Section 3(h) shall be interpreted
and applied to effectuate such purpose.

     personally liable (the "Recourse Loan").

<PAGE>

H.   The partners in the Partnership (individually, each an "Assuming Party" and
     collectively the "Assuming Parties") desire to establish among themselves
     their respective responsibilities for payment of any liability of the
     Partnership under any loans to the Partnership if the Partnership fails to
     pay them, and to release all other partners of any ultimate liability
     therefor that such partners might otherwise have under the terms of such
     loan, the Partnership Agreement or applicable law.


                                    AGREEMENT

NOW, THEREFORE, in order to formalize the understanding of the Assuming Parties,
to establish the amount of the Partnership's debt obligations assumed by each
Assuming Party, to relieve the General Partner from its existing primary
liability for the Recourse Loan, to declare the Assuming Parties' respective
shares of nonrecourse debts of the Partnership, and to amend the Partnership
Agreement as provided herein, the parties agree as follows:

1.    ASSUMPTION OF LIABILITY.

(a)  By execution of this Agreement, each Assuming Party hereby unconditionally
assumes personal liability, without right of contribution from the General
Partner or any other Assuming Party, to pay pursuant to the terms of the
Recourse Loan, whose terms are incorporated herein by this reference, or any
successor credit agreement, the percentage of the sum of Recourse Loan principal
now or existing hereafter and all interest thereon as set forth next to their
names solely in the event the Partnership fails to pay all principal and
interest due under the terms of the Recourse Loan and only after all cash and
other assets of the Partnership have been used to satisfy the liabilities of the
Partnership including such loan:

<TABLE>
<CAPTION>
                                         PERCENTAGE OF
                    PARTNERS         RECOURSE LOAN ASSUMED
                 <S>                          <C>
                 The Company                    0%

                 ______________               ___%

                 ______________               ___%
</TABLE>

(b)  An Assuming Party shall not be liable to the Partnership or any other
Assuming Party for any more of the unpaid balance of the Recourse Loan than his
or its percentage share provided in Paragraph 1(a).  Each Assuming Party shall
share liability for nonrecourse debts of the Partnership for income tax purposes
in the manner provided in the Partnership Agreement.  No Assuming Party shall
have any obligation under a Deficit Make-Up Provision of the Partnership
Agreement if that will result in the Assuming Party's bearing a greater share of
the Recourse Loan or the nonrecourse debts of the Partnership than is provided
by this Agreement.

(c)  Payments of the Recourse Loan made by the Partnership (and not by any

<PAGE>

Assuming Party personally) shall be credited pro rata against the amounts
assumed by the Assuming Parties under Paragraph 1(a).

2.  DIRECTION TO PAY LENDER.  If required by the Lender, each Assuming Party
agrees to remit to the Lender, or to the Partnership, all amounts payable by
such Party by reason of this Agreement, and each Assuming Party hereby
authorizes and directs the Partnership and the Company to pay over such amounts
to the Lender.  Each Assuming Party further agrees that the Partnership may pay
directly to the Lender from its funds any amounts due to such Party from the
Partnership up to the amount the Assuming Party is obligated to pay the Lender
by reason of this Agreement, if the Assuming Party defaults in any payment
obligation assumed by and allocated to the Assuming Party under this Agreement.
The Assuming Parties hereby authorize and direct the Company to make such
payments on behalf of the Partnership.

3.  INDEMNIFICATION.  Each Assuming Party hereby agrees to indemnify and hold
harmless every other partner in the Partnership against any and all liability,
costs, damages, attorneys' fees and other expenses that any such other partners
may incur with respect to the Recourse Loan from any failure by the Assuming
Party to satisfy its proportionate liability for such indebtedness as provided
in Paragraph 1.

4.  ACCOUNTING.  The Company shall maintain books and records setting forth the
amount of the liabilities assumed under this Agreement and the amounts applied
by the Company pursuant to the direction and authorization in Paragraph 2,
hereof, to the reduction of such liabilities, including any amounts paid by the
Company or the Partnership to the Lender upon any default in payment by any
Assuming Party.  The Company shall provide to an Assuming Party a statement of
any change in the amount of any such liability upon request by the Assuming
Party.

5.  DEFAULT.  An Assuming Party shall be in default under this Agreement in the
event: (i) he or it fails to pay when due any amount he or it is required to pay
under the Recourse Loan by reason of this Agreement; (ii) he or it fails to
satisfy any condition or to honor and perform any covenant set forth in
Paragraphs 1, 2, or 3 above; or (iii) he or it fails to pay when due any amount
he or it owes to the Lender hereunder. In the event of such default:

(a)  All amounts owed by the defaulting Assuming Party under the Recourse Loan 
by reason of this Agreement will become due and payable in full immediately;

(b)  The Lender shall have all rights and remedies set forth herein, and as
otherwise provided by law to collect all amounts due and payable by such
defaulting Assuming Party.  The Lender shall have the right to enforce one or
more of such remedies, successively or concurrently, and any action to enforce
the same shall not bar the Lender from pursuing any further remedy which it may
have hereunder or otherwise as provided by law, including, without limitation,
the absolute right on the part of the Lender to commence an action against a
defaulting Assuming Party for a judgment in the amount of all sums due and
collectible from such Assuming Party under this Agreement; and

(c)  This Agreement and the obligations and rights of the Assuming Party
hereunder are further subject to all remedies and rights of enforcement of the
Lender under the Recourse Loan solely to the extent of an Assuming Party's
liabilities thereunder by reason of this Agreement.

6.  GOVERNING LAW.  This Agreement is governed by and construed under the 
laws of 

<PAGE>

the State of California without regard to any principles governing 
conflicts of laws.

7.  AGREEMENT FOR THE BENEFIT OF THE LENDER.  Each Assuming Party agrees that 
this Agreement is made for the benefit of the Lender.  After execution of 
this Agreement it shall be delivered to the Lender upon the Lender's request, 
and the Lender shall be entitled to proceed against an Assuming Party under 
this Agreement as if the Assuming Party had made and issued his or its 
personal note directly to the Lender in an amount equal to his or its total 
obligations hereunder.

8.  NOTICES.  All notices and information to be submitted to an Assuming Party
shall be sent to him or it at 10050 Bandley Drive, Cupertino, California 95014.

9.  COUNTERPARTS.  This Agreement may be executed in several counterparts, 
and all so executed shall constitute one agreement which shall be binding on 
all the parties hereto.

<PAGE>

      IN WITNESS WHEREOF, the Assuming Parties, the Company and the Partnership
have executed this Agreement as of July 1, 1998.

2. RIGHT TO TENDER L.P. UNITS.

      2.1  GENERAL. Upon the terms and subject to the conditions of this
Agreement, after the first anniversary hereof each holder of L.P. Units shall
have the right to tender to the Company outstanding L.P. Units; provided, that
prior to the first anniversary of this Agreement, holders of L.P. Units may
tender L.P. Units solely in connection with (i) the registration of shares of
Common Stock acquired upon exchanging L.P. Units for Common Stock pursuant to a

<PAGE>

registered public offering of Common Stock initiated by the Company to the
extent of 25% of the total shares sold in the offering (subject to the Ownership
Limit and the underwriter's unlimited right to reduce the participation of all
selling shareholders) and (ii) the registration of an aggregate of 500,000
shares of Common Stock acquired upon exchanging L.P. Units into such shares of
Common Stock on a Form S-3, or any successor form thereto (subject to the
Ownership Limit). Any registration of Common Stock received in exchange for L.P.
Units pursuant to this Section 2 shall comply in all respects with Section 8
hereof.

      2.2  CERTAIN LIMITATIONS.  Notwithstanding any other provision of this
Agreement to the contrary, no Common Stock or cash shall be issued or paid in
respect of any tender of L.P. Units (i) if the right to tender L.P. Units and
receive Common Stock or cash would result in the Company not satisfying the REIT
Requirements in any respect or would result in any person or entity Beneficially
Owning Common Stock exceeding the applicable Ownership Limit, (ii) prior to the
expiration or termination of the waiting period applicable to such exchange and
issuance, if any, under the Hart-Scott-Rodino Antitrust Improvement Act of 1976,
as it may be amended from time to time, or (iii) prior to the receipt of all
governmental and regulatory approvals which are required to be obtained prior to
such tender and issuance or payment. Such holder shall, as a condition to any
tender of L.P. Units which would result in any Limited Partner, together with
such Limited Partner's Affiliates, Beneficially Owning, in the aggregate more
than shares of outstanding Common Stock exceeding the applicable Ownership
Limit, give not less than ninety (90) days' written notice to the Company of its
intent to tender L.P. Units. In the event that the ability to receive Common
Stock or cash would result in the Company not satisfying the REIT Requirements
in any respect or would result in any person or entity Beneficially Owning
Common Stock exceeding the Ownership Limit, and as a result thereof no Common
Stock or cash may be issued or paid in respect of any tender of L.P. Units
pursuant to subsection (i) above, the parties hereto shall use their respective
best efforts to restructure the terms and provisions of this Agreement (and, if
necessary, the Partnership Agreement), or to agree to terms and provisions in
addition to such terms and provisions, so as to provide to each such party the
same substantive rights (or substantive rights as close thereto as is reasonably
practicable) as those provided by this Agreement and the Partnership Agreement.

      2.3 NATURE OF THE OFFER. The right to exchange L.P. Units pursuant to this
Agreement constitutes a continuous offer and may not be withdrawn, amended or
modified by the Company without the prior written consent of each holder of
outstanding L.P. Units adversely affected by such withdrawal, amendment or
modification; provided that any withdrawal, amendment or modification that does
not adversely affect any holder of outstanding L.P. Units may be effected
without the consent of such holder.

3. ACCEPTANCE OF TENDER; ELECTION OF METHOD OF PAYMENT FOR TENDERED L.P. UNITS.

      3.1 FORM OF TENDER. Upon the terms and subject to the conditions of this
Agreement, the Company shall accept L.P. Units validly tendered in proper form
and meeting all of the requirements of this Agreement. In order for L.P. Units
to be validly tendered pursuant to this Agreement, the registered holder thereof
shall deliver to the Company, at the address provided pursuant to Section 12 (i)
a completed and duly executed Letter of Transmittal in the form attached hereto
as Exhibit A (the "Letter of Transmittal") and any other documents required by
the Letter of Transmittal and (ii) a calculation, to the best knowledge of such
registered holder after due inquiry (together with such supporting documentation
as the Company may reasonably request), of the maximum number of shares of

<PAGE>

Common Stock that may be issued to such registered holder without causing either
(x) the Company to not satisfy the REIT Requirements in any respect or (y) any
person or entity to Beneficially Own Common Stock in excess of the applicable
Ownership Limit. The Company shall make all determinations as to the validity
and form of any tender of L.P. Units in accordance with the provisions of this
Agreement and upon rejection of a tender shall give the tendering holder written
notice of such rejection, which shall include the reasons therefor.

      3.2  REVOCABILITY. Unless otherwise agreed to by the Company, tenders of
L.P. Units pursuant to this Agreement shall be irrevocable and shall not be
subject to withdrawal or modification; provided that if the Company makes the
Stock Election (as defined below) with respect to a tender, then within three
(3) days after such Stock Election the tendering holder may elect to revoke such
tender so long as (i) no public disclosure of such tender has been made prior to
such revocation and (ii) such tendering holder reimburses the Company for all
reasonable costs and expenses incurred in connection with such tender.

      3.3 COMPANY ELECTIONS. Within fifteen (15) days after the valid tender of
L.P. Units pursuant to this Agreement, the Company shall make an election to pay
for such L.P. Units by delivering either (i) Common Stock (the "Stock
Election"), (ii) cash (the "Cash Election") or (iii) a combination of Common
Stock and cash (the "Combined Election").

4.    STOCK ELECTION.

      4.1 STOCK EXCHANGE. If with respect to any tender of L.P. Units pursuant
to this Agreement, the Company makes the Stock Election, then within twenty (20)
days after such tender the Company shall deliver to the tendering holder one
share of Common Stock for each L.P. Unit validly tendered pursuant to the
provisions of this Agreement, as adjusted pursuant to Section 7.

      4.2  FRACTIONAL SHARES. No fractional shares or scrip representing
fractional shares shall be issued upon exchange of L.P. Units pursuant to this
Agreement. If more than one Letter of Transmittal shall be delivered at one time
by the same holder, the number of full shares which shall be issuable upon
exchange of the L.P. Units tendered thereby shall be computed on the basis of
the aggregate number of L.P. Units so tendered. Instead of any fractional shares
which would otherwise be issuable upon exchange of any L.P. Units, the Company
shall pay a cash adjustment in respect of such fraction in an amount equal to
the same fraction of the Closing Price.

      4.3 TAXES.  If a holder exchanges L.P. Units pursuant to this 
Agreement, the Company shall pay any documentary, stamp or similar issue or 
transfer tax due on any issue of Common Stock upon such exchange. Such 
holder, however, shall (i) pay to the Company the amount of any additional 
documentary, stamp or similar issue or transfer tax which is due (or shall 
establish to the satisfaction of the Company the payment thereof) as a result 
of Common Stock being issued in a name other than the name of such holder and 
(ii) be responsible for all income or other taxes as a result of such 
exchange.

5.    CASH ELECTION.

      If with respect to any tender of L.P. Units pursuant to this Agreement,
the Company makes the Cash Election, then within thirty (30) days after such
tender the Company shall pay to the tendering holder an aggregate amount of cash
(the "Aggregate Cash Payment") equal to the product of (i) the number of shares
of Common Stock which would have been delivered to such holder if the Company

<PAGE>

had made the Stock Election with respect to such tender and (ii) the average
Closing Price for the ten (10) trading day period ending one (1) day prior to
the date of such tender.

6.    COMBINED ELECTION.

      If with respect to any tender of L.P. Units pursuant to this Agreement,
the Company shall make the Combined Election, then within thirty (30) days after
such tender the Company shall (i) notify the tending holder of the number of
such tendered L.P. Units which will be exchanged for cash (the "Cash Units") and
the number of such tendered L.P. Units which will be exchanged for Common Stock
(the "Stock Units") as adjusted pursuant to Section 7, (ii) pay to the tendering
holder, in respect of each Cash Unit validly tendered pursuant to the provisions
of this Agreement, an amount of cash equal to the average Closing Price for the
ten trading-day period ending one (1) day prior to the date of such tender and
(iii) deliver to the tendering holder one share of Common Stock for each Stock
Unit validly tendered pursuant to the provisions of this Agreement.

The provisions of Sections 4.2 and 4.3 of this Agreement shall apply to the
issuance of Common Stock pursuant to this Section 6.

7.    EXCHANGE FACTOR; ADJUSTMENTS TO EXCHANGE FACTOR.

      7.1  EXCHANGE FACTOR. Pursuant to Sections 4, 5 and 6, each L.P. Unit
initially shall be exchangeable, without the payment of additional consideration
by the holder thereof, into one (1) share of Common Stock or the equivalent
thereof in cash. The number of L.P. Units exchangeable for one share of Common
Stock ("Exchange Factor") shall be subject to adjustment as hereinafter
provided.

      7.2  ADJUSTMENT FOR STOCK SPLITS, DIVIDENDS AND Combinations. If the
Company at any time or from time to time after the date hereof shall effect a
subdivision of the outstanding Common Stock, or shall fix a record date for
determination of shareholders entitled to receive a dividend of Common Stock on
its outstanding Common Stock, the Exchange Factor then in effect immediately
before such subdivision or as of such record date shall be proportionately
reduced, and if the Corporation shall combine the outstanding shares of Common
Stock, the Exchange Factor then in effect immediately before the combination
shall be proportionately increased. Any adjustment under this Section 7.2 shall
become effective at the close of business on the date the subdivision or
combination becomes effective or on the record date for determining holders of
any class of securities entitled to receive the dividend; provided that if such
record date shall have been fixed and such dividend shall not have been fully
paid on the date fixed therefor, the adjustment previously made in the Exchange
Factor that became effective on such record date shall be cancelled as of the
close of business on such record date, and thereafter the Exchange Factor shall
be adjusted pursuant to this Section 7.2 as of the time of actual payment of
such dividend.

      7.3  ADJUSTMENTS FOR OTHER DIVIDENDS AND DISTRIBUTIONS. In the event the
Company at any time or from time to time shall make or issue, or fix a record
date for the determination of holders of Common Stock entitled to receive, a
dividend or other distribution payable in securities of the Company other than
shares of Common Stock, then and in each such event provision shall be made so
that the holders of L.P. Units shall receive upon exchange thereof, in addition
to the number of shares of Common Stock receivable thereupon, the amount of such
securities of the Company that they would have received had their L.P. Units

<PAGE>

been exchanged into Common Stock on the date of such event, giving effect to all
adjustments called for with respect to such securities during the period from
the date of such event to and including the exchange date.

      7.4  ADJUSTMENT FOR RECLASSIFICATION, EXCHANGE AND SUBSTITUTION. If the
Common Stock issuable upon exchange of the L.P. Units shall be changed into the
same or different number of shares of any class or series of stock, whether by
capital reorganization, reclassification or otherwise (other than a subdivision
or combination of shares or stock dividend provided for in Sections 7.1 and 7.2
above, or a merger, consolidation, sale of assets or other transaction provided
for in Section 7.3 below), then and in each such event the holder of each L.P.
Unit shall have the right thereafter to exchange such share into the kind and
amount of shares of stock and other securities and property receivable upon such
reorganization, reclassification or other change by holders of the number of
shares of Common Stock into which such L.P. Unit might have been exchanged
immediately prior to such reorganization, reclassification or change, all
subject to further adjustment as provided herein.

      7.5  ADJUSTMENT FOR MERGER OR REORGANIZATION, ETC. In the event of any
merger or consolidation of the Company with or into another corporation or the
conveyance of all or substantially all of the assets of the Company to another
corporation, each L.P. Unit shall thereafter be exchangeable into the number of
shares of stock or other securities or property to which a holder of the number
of shares of Common Stock of the Company deliverable upon exchange of such L.P.
Units would have been entitled upon such consolidation, merger or conveyance;
and, in any such case, appropriate adjustment (as determined by the Board of
Directors) shall be made in the application of the provisions herein set forth
with respect to the rights and interest thereafter of the holders of the L.P.
Units, to the end that the provisions set forth herein (including provisions
with respect to changes in and other adjustments of the Exchange Factor) shall
thereafter be applicable, as nearly as reasonably may be, in relation to any
share of stock or other property thereafter deliverable upon exchange of L.P.
Units.

      7.6  NO IMPAIRMENT. The Company will not, by amendment of this Agreement 
or through any reorganization,  transfer of assets,  consolidation,  merger,
dissolution, issue or sale of securities or any other voluntary action, avoid or
seek to avoid the observance or performance of any of the terms to be observed
or performed under this Section 7 and in the taking of all such action as may be
necessary or appropriate in order to protect the Exchange Rights of the holders
of L.P. Units against impairment.

      7.7  CERTIFICATE AS TO ADJUSTMENTS. Upon the occurrence of each adjustment
or readjustment of the Exchange Factor pursuant to this Section 7, the Company
at its expense shall promptly compute such adjustment or readjustment in
accordance with the terms hereof and furnish to each holder of L.P. Units, a
certificate setting forth such adjustment or readjustment and showing in detail
the facts upon which such adjustment or readjustment is based. The Company
shall, upon the written request at any time of any holder of L.P. Units, furnish
or cause to be furnished to such holder a like certificate setting forth (i)
such adjustments and readjustments, (ii) the ratio at which exchanges of L.P.
Units would be made at the time, and (iii) the number of shares of Common Stock
and the amount, if any, of other property which at the time would be received
upon exchange of such holder's L.P. Units.

8.    REGISTRATION RIGHTS.

<PAGE>

      The Company shall provide the following registration rights to the Limited
Partners:

      8.1 DEFINITIONS. For purposes of this Section 8:

           (a) The term "REGISTER", "REGISTERED", and "REGISTRATION" refer to a
registration effected by preparing and filing a registration statement or
similar document in compliance with the Securities Act and the declaration or
ordering of effectiveness of such registration statement or document;

           (b) The term "REGISTRABLE SECURITIES" means (1) the Common Stock of
the Company issued upon exchange of the L.P. Units (the "Exchange Stock") and
(2) any Common Stock of the Company issued as (or issuable upon the conversion
or exercise of any warrant, right, or other security which is issued as) a
dividend or other distribution with respect to, or in exchange for or in
replacement of, such Exchange Stock, excluding in all cases, however, any
Registrable Securities sold by a person in a transaction in which such person's
rights under this Agreement or the Partnership Agreement were not assigned in
conformity with this Agreement or the Partnership Agreement;

           (c) For this purpose, "REGISTRATION EXPENSES" mean any and all
expenses of the Company incident to performance of or compliance with this

           Agreement, including, without limitation, (i) all SEC and securities
exchange registration and filing fees, (ii) all printing, messenger and deliver
expenses, (iii) all fees and expenses incurred in connection with the listing of
the Registrable Securities on any securities exchange, and the fees and
disbursements of counsel for the Company and of its independent public
accountants, but excluding underwriting discounts and commissions and transfer
taxes, if any;

           (d) The term "FORM S-3" or "FORM S-11" means such form under the
Securities Act as in effect on the date hereof or any registration form under
the Securities Act subsequently adopted by the SEC which permits inclusion or
incorporation of substantial information by reference to other documents filed
by the Company with the SEC.

      8.2  COMPANY REGISTRATION. If (but without any obligation to do so) the
Company proposes to register (including for this purpose a registration effected
by the Company for shareholders other than the Limited Partners) any of its
stock or other securities under the Securities Act of 1933, as amended (the
"Securities Act") in connection with the public offering of such securities
solely for cash (other than a registration relating solely to the sale of
securities to participants in a Company stock plan, or a registration on any
form which does not include substantially the same information as would be
required to be included in a registration statement covering the sale of the
Registrable Securities), the Company shall, at such time, promptly give each
Limited Partner written notice of such registration. Upon the written request of
each Limited Partner given within twenty (20) days after mailing of such notice
by the Company in accordance with Section 12 of this Agreement, the Company
shall, subject to the provisions of paragraph 8.9 below, cause to be registered
under the Securities Act the Registrable Securities that each such Limited
Partner has requested to be registered to the extent of 25% of the total shares
to be sold in the offering.

      8.3 SHELF REGISTRATION. At any time, from time to time, following the
first anniversary of the date of the Agreement, upon the request of Limited

<PAGE>

Partners holding at least five percent (5%) of the Registrable Securities
("Participating Limited Partners"), the Company shall file, and use its best
efforts to have declared effective under the Securities Act by the sixtieth
(60th) day after the date the Company receives such request, a "shelf"
registration statement pursuant to the requirements of the Securities Act on
Form S-3 or another appropriate form pursuant to Rule 415 under the Securities
Act (or any successor rule or regulation) covering the disposition of at least
200,000 shares of the Registrable Securities in one or more underwritten
offerings, block transactions, broker transactions, at-the-market transactions,
and in such other manner or manners as may be specified by such Participating
Limited Partners, PROVIDED, HOWEVER , that the Company is only obligated to
effect one (1) such registration in any twelve (12)-month period. The Company
shall use its best efforts to keep such "shelf" registration continuously
effective as long as the delivery of a prospectus is required under the
Securities Act in connection with the disposition of the Registrable Securities
registered thereby and in furtherance of such obligation, shall supplement or
amend such registration statement if, as, and when required by the rules,
regulations and instructions applicable to the form used by the Company for such
registration or by the Securities Act or by any other rules and regulations
thereunder applicable to "shelf" registrations. The Company shall provide the
Participating Limited Partners with written notice of the filing of such "shelf"
registration statement within five (5) days after such registration statement
has been filed with the Securities and Exchange Commission ("SEC"). If the
Company delivers to the Participating Limited Partners a certificate signed by
the President of the Company stating that in the good faith judgment of the
Board of Directors of the Company, it would be detrimental to the Company or its
shareholders for the Participating Limited Partners to offer or sell, or to
continue to offer and sell, any Registrable Securities under the shelf
registration statement for a period set forth in such certificate not to exceed
one hundred twenty (120) days and commencing no earlier than ten (10) days after
the date such certificate is so delivered (the "Blackout Period"), the Limited
Partners shall not offer or sell any Registrable Securities during such Blackout
Period, provided that the Company shall have the right to deliver such a
certificate only once during any twelve (12) month period.

      8.4  REQUESTS FOR REGISTRATION.

           (a) Notwithstanding the limitations set forth in Section 8.3 above,
subject to the Ownership Limit and the discretion of the Company, all Limited
Partners in the aggregate may request the registration of L.P. Units prior to
the first anniversary of the Closing Date in connection with the registration of
an aggregate of 500,000 shares of Common Stock on a Form S-3 or another
appropriate form pursuant to Rule 415 under the Securities Act (or any successor
rule or regulation), upon converting L.P. Units into shares of Common Stock.
Such registration shall be subject to the Blackout Period described in Section
8.3.

           (b) If the Company shall receive a written request from Limited
Partners holding no fewer that 500,000 L. P. Units (the "Initiating Holders")
and the Company is not then eligible to file a registration statement on Form
S-3 or another appropriate form pursuant to Rule 415 of the Securities Act (or
any successor rule or regulation) in accordance with the requirements of Section
8.3, the Company shall promptly give written notice of such request to all
Limited Partners and shall, subject to the limitations set forth below, effect
as soon as practicable, and in any event with in one hundred twenty (120) days
of the receipt of such request, a registration on Form S-11, or an equivalent
form, of all Registrable Securities which the Limited Partners request to be

<PAGE>

registered within twenty (20) days of the mailing of such notice by the Company
in accordance with Section 12 hereof in an underwritten public offering. The
underwriter will be selected by a majority in interest of the Initiating Holders
and shall be an underwriter of nationally recognized standing reasonably
acceptable to the Company. In such event, the right of any Limited Partner to
include such Limited Partner's Registrable Securities in such registration shall
be conditioned upon such Limited Partner's participation in such underwriting
and the inclusion of such Limited Partner's Registrable Securities in the
underwriting to the extent provided herein. All Limited Partners proposing to
distribute their securities through such underwriting shall (together with the
Company) enter into an underwriting agreement in customary form with the
underwriter or underwriters selected for such underwriting. Notwithstanding any
other provision of this Section 8.4(b), if the underwriter advises the
Initiating Holders in writing that marketing factors require a limitation of the
number of shares to be underwritten, then the Initiating Holders shall so advise
all Limited Partners proposing to distribute Registrable Securities which would
otherwise be underwritten pursuant hereto, and the number of shares of
Registrable Securities that may be included in the underwriting shall be
allocated among all Limited Partners, including the Initiating Holders, in
proportion (as nearly as practicable) to the amount of Registrable Securities of
the Company owned by each Holder; provided however, that the number of shares of
Registrable Securities to be included in such underwriting shall not be reduced
unless all other securities to be offered for sale by any security holder are
first entirely excluded from the underwriting. In addition, any registration
pursuant to this Section 8.4(b) shall be subject to the Blackout Period
described in Section 8.3.

      8.5  OBLIGATIONS OF THE PARTIES.

           (a) Whenever required under Section 8.2, 8.3 or 8.4 to effect the
registration of any Registrable Securities, the Company shall, as expeditiously
as reasonably possible:

               (i)   prepare and file with the SEC a registration statement with
respect to such Registrable Securities and use its best efforts to cause such
registration statement to become effective, and, upon the request of a Limited
Partner, keep such registration statement effective until the completion of the
sale of the Registrable Securities subject to the registration statement,
subject to the provisions of Section 8.3;
 
               (ii)  prepare and file with the SEC such amendments and
supplements to such registration statement and the prospectus used in connection
with such registration statement as may be necessary to comply with the
provisions of the Securities Act with respect to the disposition of all
securities covered by such registration statement;

               (iii) furnish to the Limited Partners such numbers of copies of a
prospectus, including a preliminary prospectus, in conformity with the
requirements of the Act, and such other documents as they may reasonably request
in order to facilitate the disposition of Registrable Securities owned by the
Limited Partners;

               (iv)  use its best efforts to register and qualify the securities
covered by such registration statement under such other securities or Blue Sky
laws of such jurisdictions as shall be reasonably requested by the Limited
Partner, provided that the Company shall not be required in connection therewith
or as a condition thereto to qualify to do business or to file a general consent

<PAGE>

to service of process in any such states or jurisdictions;

               (v)   in the event of any underwritten public offering, enter 
into and perform its obligations under an underwriting agreement, in usual and
customary form, with the managing underwriter of such offering. The Limited
Partner shall also enter into and perform its obligations under such an
agreement; and

               (vi) notify the Limited Partners at any time when a prospectus
relating thereto is required to be delivered under the Securities Act of the
happening of any event as a result of which the prospectus included in such
registration statement, as then in effect, includes an untrue statement of a
material fact or omits to state a material fact required to be stated therein or
necessary to make the statements therein not misleading in light of the
circumstances then existing.

           (b) When requested by Limited Partners in connection with a "shelf"
registration pursuant to Section 8.3, the Company shall assist the Limited
Partners in obtaining a firm commitment underwriting agreement for such resales
from a qualified investment banking firm, as determined by the Company.

           (c) The Limited  Partners agree that in connection with any
registration of the Registrable Securities by the Company pursuant to Section
8.2, 8.3 or 8.4, except as permitted under Regulation M promulgated under the
Exchange Act, if the Registrable Securities of Holder are being distributed
pursuant to such registration, the Limited Partners shall not, directly or
indirectly, by the use of any means or instrumentality of interstate commerce,
or the mails, or any facility of any national securities exchange, either alone
or with one or more persons, bid for or purchase for any account in which any
Limited Partner has a beneficial interest, any shares of the Common Stock of the
Company until such Limited Partner has completed the Limited Partner's
participation in such distribution.

      8.6  FURNISH INFORMATION. It shall be a condition precedent to the
obligations of the Company to take any action pursuant to Sections 8.2, 8.3 or
8.4 with respect to the Registrable Securities of a Limited Partner that the
Limited Partner shall furnish to the Company such information regarding itself,
the Registrable Securities held by it, and the intended method of disposition of
such securities as shall be required to effect the registration of such Limited
Partner's Registrable Securities.

      8.7  EXPENSES OF REQUESTED REGISTRATIONS. In connection with 
registrations, filings, or qualifications pursuant to Sections 8.3 or 8.4, the 
Company shall pay all Registration Expenses, other than selling expenses  
(including commissions and separate counsel' fees of the Limited Partners).

      8.8  EXPENSES OF COMPANY REGISTRATION. The Company shall bear and pay all
expenses incurred by the Company in connection with any registration, filing, or
qualification of Registrable Securities with respect to registrations pursuant
to Section 8.2 and the closing of the sale thereof, including (without
limitation) all registration, filing, qualification, printer's fees, attorneys'
and accounting fees and expenses; provided, however, that the Company shall not
be responsible for underwriting discounts and commissions or other charges
relating to the Registrable Securities, or for the Limited Partners' attorneys'
fees and expenses or any taxes imposed with respect to the Registrable
Securities on the sale and transfer thereof.

<PAGE>

      8.9  UNDERWRITING REQUIREMENTS. In connection with any offering involving
an underwriting of shares of the Company's capital stock pursuant to Section
8.2, Limited Partners may include up to 25% of the shares sold in the offering,
provided however, that the Company shall not be required under Section 8.2, to
include any of the Limited Partners' Registrable Securities in such underwriting
unless the Limited Partner accepts the terms of the underwriting as agreed upon
between the Company and the underwriters selected by it (or by other persons
entitled to select the underwriters), and then only in such quantity as the
underwriters determine in their sole discretion will not jeopardize the success
of the offering by the Company. If the total amount of securities, including
Registrable Securities, requested by the Participating Limited Partners to be
included in such offering exceeds the amount of securities sold other than by
the Company that the underwriters determine in their sole discretion is
compatible with the success of the offering, the Company shall be required to
include in the offering only that number of such securities, including
Registrable Securities, which the underwriters determine in their sole
discretion will not jeopardize the success of the offering (the securities so
included to be apportioned pro rata among the selling shareholders according to
the total amount of securities entitled to be included therein owned by each
selling shareholder or in such other proportions as shall mutually be agreed to
by such selling shareholders). For purposes of the preceding parenthetical
concerning apportionment, for any selling shareholder which is a Participating
Limited Partner of Registrable Securities and which is a partnership or
corporation, the partners, retired partners, and shareholders of such holder, or
the estates and family members of any such partners and retired partners and any
trusts for the benefit of any of the foregoing persons shall be deemed to be a
single "selling shareholder", and any pro rata reduction with respect to such
"selling shareholder" shall be based upon the aggregate amount of shares
carrying registration rights owned by all entities and individuals included in
such "selling shareholder", as defined in this sentence.

      8.10 DELAY OF REGISTRATION. The Limited Partners shall not have any right
to obtain or seek an injunction restraining or otherwise delaying any such
registration as the result of any controversy that might arise with respect to
the interpretation or implementation of any provision of this Section 8.

      8.11 INDEMNIFICATION. In the event any Registrable Securities are included
in a registration statement under this Section 8:

           (a) To the extent permitted by law, the Company will indemnify and
hold harmless a Limited Partner, any underwriter (as defined in the Act) for a
Limited Partner and each person, if any, who controls a Limited Partner or
underwriter within the meaning of the Act or the Exchange Act, against any
losses, claims, damages, or liabilities (joint or several) to which they may
become subject under the Act, or the Exchange Act, or other federal or state
law, insofar as such losses, claims, damages, or liabilities (or actions in
respect thereof) arise out of or are based upon any of the following statements,
omissions or violations (collectively a "Violation"): (i) any untrue statement
or alleged untrue statement of a material fact contained in such registration
statement, including any preliminary prospectus or final prospectus contained
therein or any amendments or supplements thereto, (ii) the omission or alleged
omission to state therein a material fact required to be stated therein, or
necessary to make the statements therein not misleading, or (iii) any violation
or alleged violation by the Company of the Act, the Exchange Act, any state
securities law or any rule or regulation promulgated under the Act, or the
Exchange Act or any state securities law; and the Company will pay to a Limited
Partner, underwriter or controlling person, as incurred, any legal or other

<PAGE>

expenses reasonably incurred by them in connection with investigating or
defending any such loss, claim, damage, liability, or action; PROVIDED, HOWEVER,
that the indemnity agreement contained in this subsection (a) shall not apply to
amounts paid in settlement of any such loss, claim, damage, liability, or action
if such settlement is effected without the consent of the Company (which consent
shall not be unreasonably withheld), nor shall the Company be liable to any
indemnitee for any such loss, claim, damage, liability, or action to the extent
that it arises out of or is based upon a Violation which occurs in reliance upon
and in conformity with written information furnished by such indemnitee
expressly for use in connection with such registration.

           (b) To the extent permitted by law, a Limited Partner will indemnify
and hold harmless the Company, each of its directors, each of its officers who
has signed the registration statement, each person, if any, who controls the
Company within the meaning of the Act, any underwriter, any other shareholder
selling securities in such registration statement and any controlling person of
any such underwriter or other shareholder, against any losses, claims, damages,
or liabilities (joint or several) to which any of the foregoing persons may
become subject, under the Act, or the Exchange Act, or other federal or state
law, insofar as such losses, claims, damages, or liabilities (or actions in
respect thereto) arise out of or are based upon any Violation, in each case to
the extent (and only to the extent) that such Violation occurs in reliance upon
and in conformity with written information furnished by a Limited Partner
expressly for use in connection with such registration; and a Limited Partner
will pay, as incurred, any legal or other expenses reasonably incurred by any
person intended to be indemnified pursuant to this subsection (b), in connection
with investigating or defending any such loss, claim, damage, liability, or
action; PROVIDED, HOWEVER, that the indemnity agreement contained in this
subSection (b) shall not apply to amounts paid in settlement of any such loss,
claim, damage, liability or action if such settlement is effected without the
consent of the a Limited Partner, which consent shall not be unreasonably
withheld; and PROVIDED, THAT, in no event shall any indemnity obligation under
this subsection (b) (together with any obligation to contribute under subsection
(d)) exceed the gross proceeds from the offering received by a Limited Partner.

           (c) Promptly after receipt by an indemnified party under this Section
8.11 of notice of the commencement of any action (including any governmental
action), such indemnified party will, if a claim in respect thereof is to be
made against any indemnifying party under this Section 8.11, deliver to the
indemnifying party a written notice of the commencement thereof and the
indemnifying party shall have the right to participate in, and, to the extent
the indemnifying party so desires, jointly with any other indemnifying party
similarly noticed, to assume the defense thereof with counsel mutually
satisfactory to the parties; PROVIDED, HOWEVER, that an indemnified party
(together with all other indemnified parties which may be represented without
conflict by one counsel) shall have the right to retain one separate counsel,
with the fees and expenses to be paid by the indemnifying party, if 
representation of such indemnified party by the counsel retained by the
indemnifying party would be inappropriate due to actual or potential differing
interests between such indemnified party and any other party represented by such
counsel in such proceeding. The failure to deliver written notice to the
indemnifying party within a reasonable time of the commencement of any such
action, if prejudicial to its ability to defend such action, shall relieve such
indemnifying party of any liability to the indemnified party under this Section
8.11, but the omission so to deliver written notice to the indemnifying party
will not relieve it of any liability that it may have to any indemnified party
otherwise than under this Section 8.11.

<PAGE>

           (d) If the indemnification provided for in this Section 8.11 is held
by a court of competent jurisdiction to be unavailable to an indemnified party
with respect to any loss, liability, claim, damage, or expense referred to
therein, then the indemnifying party, in lieu of indemnifying such indemnified
party hereunder, shall contribute to the amount paid or payable by such
indemnified party as a result of such loss, liability, claim, damage, or expense
in such proportion as is appropriate to reflect the relative fault of the
indemnifying party on the one hand and of the indemnified party on the other in
connection with the statements or omissions that resulted in such loss,
liability, claim, damage, or expense as well as any other relevant equitable
considerations. The relative fault of the indemnifying party and of the
indemnified party shall be determined by reference to, among other things,
whether the untrue or alleged untrue statement of a material fact or the
omission to state a material fact relates to information supplied by the
indemnifying party or by the indemnified party and the parties' relative intent,
knowledge, access to information, and opportunity to correct or prevent such
statement or omission. In no event shall any a Limited Partner's obligation to
contribute under this subsection (d) (together with any obligation to indemnify
under subSection (b)) exceed the gross proceeds from the offering received by
such a Limited Partner.

           (e) Notwithstanding the foregoing, to the extent that the provisions
on indemnification and contribution contained in the underwriting agreement
entered into in connection with an underwritten public offering are in conflict
with the foregoing provisions, the provisions in the underwriting agreement
shall control.

           (f) The obligations of the Company and a Limited Partner under this
Section 8.11 shall survive the completion of any offering of Registrable
Securities in a registration statement filed pursuant to Section 8.2, 8.3 or
8.4, and otherwise.

      8.12 REPORTS UNDER SECURITIES EXCHANGE ACT OF 1934. With a view to making
available to the Limited Partners the benefits of Rule 144 promulgated under the
Securities Act and any other rule or regulation of the SEC that may at any time
permit the Limited Partners to sell securities of the Company to the public
without registration or pursuant to a registration on Form S-3, the Company
agrees to use reasonable efforts to:

           (a) make and keep public information available, as those terms are
understood and defined in SEC Rule 144, at all times;

           (b) take such action as is necessary to enable the Limited Partners
to utilize Form S-3 for the sale of Registrable Securities as soon as permitted
pursuant to this Section 8 after the date of the Agreement;

           (c) file with the SEC in a timely manner all reports and other
documents required of the Company under the Securities Act and the Exchange Act
of 1934 as amended (the "Exchange Act"); and

           (d) furnish to a Limited Partner, so long as a Limited Partner owns
any Registrable Securities, forthwith upon request (i) a written statement by
the Company that it has complied with the reporting requirements of SEC Rule
144, the Securities Act, and the Exchange Act, or that it qualifies as a
registrant whose securities may be resold pursuant to Form S-3 (at any time
after it so qualifies), (ii) a copy of the most recent annual or quarterly

<PAGE>

report of the Company and such other reports and documents so filed by the
Company, and (iii) such other information as may be reasonably requested in
availing a Limited Partner of any rule or regulation of the SEC which permits
the selling of any such securities without registration or pursuant to such
form.

      8.13 EXERCISE OF REGISTRATION RIGHTS. The rights to cause the Company to
register Registrable Securities pursuant to this Section 8 may be exercised by a
Limited Partner or by any transferee or assignee of such securities who, after
such assignment or transfer, holds at least 500,000 shares of Registrable
Securities (subject to appropriate adjustment for stock splits, stock dividends,
combinations, and other recapitalizations), provided, in the case of any such
transferee or assignee, the Company is, within a reasonable time after such
transfer, furnished with written notice of the name and address of such 
transferee or assignee and the  securities  with respect to which such
registration rights are being assigned and such transferee or assignee agrees to
comply with all obligations imposed on a Limited Partner under applicable
provisions of this Section 8; and PROVIDED, FURTHER, that such assignment shall
be effective only if immediately following such transfer the further disposition
of such securities by the transferee or assignee is restricted under the
Securities Act. For the purposes of determining the number of shares of
Registrable Securities held by a transferee or assignee, the holdings of
transferees and assignees of a partnership who are partners or retired partners
of such partnership (including spouses and ancestors, lineal descendants, and
siblings of such partners or spouses who acquire Registrable Securities by gift,
will, or intestate succession) shall be aggregated together and with the
partnership; and PROVIDED THAT all assignees and transferees who would not
qualify individually for an assignment of the registration rights as provided
herein shall have a single attorney-in-fact for the purpose of exercising any
rights, receiving notices, or taking any action under applicable provisions of
this Section 8.

      8.14 "MARKET STAND-OFF" AGREEMENT. The Limited Partners hereby agree that,
during the period of duration (not to exceed one hundred eighty (180) days)
specified by the Company and an underwriter of Common Stock or other securities
of the Company, following the effective date of any registered underwritten
public offering of the Company's securities, it shall not, to the extent
requested by the Company and such underwriter, directly or indirectly sell,
offer to sell, contract to sell (including, without limitation, any short sale),
grant any option to purchase or otherwise transfer or dispose of (other than to
donees who agree to be similarly bound) any securities of the Company held by it
at any time during such period except Common Stock included in such 
registration; PROVIDED, HOWEVER, that all officers and directors of the Company,
and all other persons with registration rights (whether or not pursuant to this
Agreement) enter into similar agreements. In order to enforce the foregoing 
covenant, the Company may impose stop-transfer instructions with respect to the
Registrable Securities of the Limited Partners (and the shares or securities of
every other person subject to the foregoing restriction) until the end of such 
period.

      8.15 DELAYED PAYMENT UNITS REGISTRATION.

      If at any time after one year from the date of this Agreement, (a) a
Limited Partner validly tenders L.P. Units pursuant to the provisions of this
Agreement, (b) the Company makes the Stock Election or the Combined Election
with respect to such tender, (c) as a result of the Ownership Limit such Limited
Partner cannot receive the full number of shares of Common Stock otherwise

<PAGE>

issuable to such Limited Partner pursuant to such tender and such election
(without giving effect to the Ownership Limit), then:

               (i)   subject to the other terms and conditions of this 
Agreement, such Limited Partner shall be entitled to receive the number of 
shares of Common Stock which it can receive pursuant to such tender, such 
election and the Ownership Limit; and

               (ii)  if such Limited Partner shall make a written request for
registration of Common Stock pursuant to this Section 8, the Company shall cause
there to be filed with the SEC a registration statement and the Company shall
register and sell pursuant thereto a number of shares of Common Stock equal to
the number of shares of such Unissued Common Stock. Within two (2) business days
after the receipt by the Company of the proceeds of any sale (after underwriting
discounts and commissions) of such Common Stock pursuant to such registration,
the Company shall pay such proceeds to the tendering holder of the Delayed
Payment Units, in full payment for the tender of such Delayed Payment Units.

               (iii) For purposes of this Section 8.15, the number of shares of
Common Stock which such Limited Partner cannot receive pursuant to such tender
as a result of the Ownership Limit are referred to as the "Unissued Common
Stock" and the L.P. Units tendered in respect of such Unissued Common Stock are
referred to as the "Delayed Payment Units."

9.    REPRESENTATIONS OF TENDERING HOLDER.

      Each tender of L.P. Units shall constitute a representation and warranty
by the tendering holder of each of the representations and warranties set forth
in the form of Letter of Transmittal. Without limiting the generality of the
foregoing, unless, at the time of a tender for exchange of L.P. Units pursuant
to this Agreement, a registration statement relating to Common Stock to be
delivered upon such tender is effective under the Securities Act, such tender
shall constitute a representation and warranty by the tendering holder to the
Company that such tendering holder (i) is an "accredited investor" within the
meaning of Rule 501 under the Securities Act, (ii) has sufficient knowledge and

an opportunity to discuss the business, management and financial affairs of the
Operating Partnership and the Company with the management of the Operating
Partnership and the Company and (iv) understands that the Common Stock has not
been registered under the Securities Act by reason of their issuance in a
transaction exempt from the registration requirements of the Securities Act

Act and such Common Stock must be held indefinitely unless a subsequent
disposition thereof is registered under the Securities Act and applicable state
securities laws or is exempt from such registration.

Election), such holder shall continue to hold and own such L.P. Units for all

exchange.

[Mission West Properties Logo]                           GRANT PURSUANT TO
                                                      1997 STOCK OPTION PLAN

________________________, OPTIONEE:

Mission West Properties, a California corporation (the "Company"), hereby grants
to Optionee, an option ("Option") to purchase a total of __________________
(_______) shares of Common Stock ("Shares") of the Company, at the price set
forth herein, and in all respects subject to the terms, definitions and
provisions of the Company's 1997 Stock Option Plan ("Plan"), which is
incorporated herein by this reference.

THE DETAILS OF YOUR OPTION ARE AS FOLLOWS:

1.   NATURE OF THE OPTION
The Option is intended to be an incentive stock option within the meaning of
Section 422 of the Internal Revenue Code of 1986, as amended (the "Code"). To
the extent that the Option, or any portion thereof, does not qualify as an
incentive stock option under the Code because the aggregate fair market value
(determined at the grant date) of the Shares for which the Option or portion
thereof first becomes exercisable hereunder will, when added to the aggregate
fair market value (determined as of the respective date or dates of grant) of
the Shares or other securities for which the Option or one or more other
incentive stock options granted to the Optionee prior to the grant date (whether
under the Plan or any other option plan of the Corporation or any Parent or
Subsidiary) first becomes exercisable during the calendar year, exceed $100,000
in the aggregate, the Option or portion thereof shall constitute an incentive
stock option under the Plan in such calendar year only to the extent of such
$100,000 limitation. To the extent that the fair market value of the Shares for
which the Option first becomes exercisable in any calendar year exceeds such
$100,000 limitation, the Option may nevertheless be exercised for those excess
Shares in such calendar year as a "Nonstatutory Stock Option", as defined in
Section 2.o of the Plan.

2.   OPTION PRICE
The Option Price is $____________ for each Share.

3    VESTING AND EXERCISE OF OPTION
The Option shall vest and become exercisable during its term in accordance with
the provisions of Section 9 of the Plan as follows:
          a.   VESTING AND RIGHT TO EXERCISE
               i.   The Option shall vest as follows, subject to the Optionee's
               Continuous Employment with the Company:

                    NUMBER OF SHARES         DATE OF EARLIEST EXERCISE
                      (INSTALLMENT)                   (VESTING)
               ----------------------------------------------------------------


Page 1
<PAGE>

               Subject to the provisions of subparagraphs ii and iii below, the
               Optionee can only exercise the portion of the Option that is
               vested, until the expiration of the Option term.
               ii.   In the event of the Optionee's death, disability or other
               termination of employment, the exercisability of the Option shall
               be governed by Sections 9.d, e and f of the Plan.
               iii.  The Option may not be exercised for fractional shares or
               for less than ten (10) Shares
          b.   METHOD OF EXERCISE
          In order to exercise any portion of this Option, the Optionee shall
          notify the Company in writing of the election to exercise the Option,
          the number of shares in respect of which the Option is being exercised
          by executing and delivering the Notice of Exercise of Stock Option in
          the form attached hereto to the Secretary of the Company.  The
          certificate or certificates representing Shares as to which this
          Option has been exercised shall be registered in the name of the
          Optionee.
          b.   RESTRICTIONS ON EXERCISE
          This Option may not be exercised if the issuance of the Shares upon
          such exercise or the method of payment of consideration for such
          shares would constitute a violation of any applicable Federal or state
          securities law or other law or regulation.  Furthermore, the method
          and manner of payment of the Option Price will be subject to the rules
          under Part 207 of Title 12 of the Code of Federal Regulations
          ("Regulation G") as promulgated by the Federal Reserve Board if such
          rules apply to the Company at the date of exercise.  As a condition to
          the exercise of this Option, the Company may require the Optionee to
          make any representation or warranty to the Company at the time of
          exercise of this Option as in the opinion of legal counsel for the
          Company may be required by any applicable law or regulation, including
          the execution and delivery of an appropriate representation statement.
          Accordingly, the stock certificates for the Shares issued upon
          exercise of this Option may bear appropriate legends restricting
          transfer.

4.   NON-TRANSFERABILITY OF OPTION
This Option may be exercised during the lifetime of the Optionee only by the
Optionee and, subject to the provisions of Sections 9.f and 10 of the Plan, may
not be transferred in any manner other than by will or by the laws of descent
and distribution.  The terms of this Option shall be binding upon the executors,
administrators, heirs and successors of the Optionee.

5.   METHOD OF PAYMENT
Payment of the exercise price shall be by any of the following, or a combination
thereof, at the election of the Optionee:
     a.   cash;
     b.   certified or bank cashier's check;
     c.   in the event there exists a public market for the Company's Common
     Stock on the date of exercise, by delivery of a sell order to a broker for
     the shares being purchased and an agreement to pay (or have the broker
     remit payment for) the purchase price of the shares being purchased on or
     before the settlement date for the sale of such shares to the broker; or
     e.   in the event there exists a public market for the Company's Common
     Stock on the date of exercise, by surrender of shares of the Company's
     Common Stock, provided that if such shares were acquired upon exercise of
     an incentive stock option, the Optionee must have first satisfied the
     holding period requirements under Section 422(a)(1) of the Code.  In this
     case payment shall be made as follows:
          i.   Optionee shall deliver to the Secretary of the Company a written
          notice which shall set forth the portion of the purchase price the
          Optionee wishes to pay with Common Stock, and the number of shares of
          such Common Stock the Optionee intends to surrender pursuant to the
          exercise of this Option, which shall be determined by dividing the
          aforementioned portion of the purchase price by the average of the
          last reported bid and asked prices per share of Common Stock of the
          Company, as reported in THE WALL STREET JOURNAL, for the day on which
          the notice of exercise is sent or delivered;
          ii.  Fractional shares shall be disregarded and the Optionee shall pay
          in cash an amount equal to such fraction multiplied by the price
          determined under subparagraph i above;
          iii. The written notice shall be accompanied by a duly endorsed blank
          stock power with respect to the number of Shares set forth in the
          notice, and the certificate(s)

          representing said Shares shall be delivered to the Company at its
          principal offices within three (3) working days from the date of the
          notice of exercise;
          iv.  The Optionee hereby authorizes and directs the Secretary of the
          Company to transfer so many of the Shares represented by such
          certificate(s) as are necessary to pay the purchase price in
          accordance with the provisions herein;
          v.   If any such transfer of Shares requires the consent of the
          California Commissioner of Corporations or of some other agency under
          the securities laws of any other state, or an opinion of counsel for
          the Company or Optionee that such transfer may be effected under
          applicable Federal and state securities laws, the time periods
          specified herein shall be extended for such periods as the necessary
          request for consent to transfer is pending before said Commissioner or
          other agency, or until counsel renders such an opinion, as the case
          may be.  All parties agree to cooperate in making such request for
          transfer, or in obtaining such opinion of counsel, and no transfer
          shall be effected without such consent or opinion if required by law;
          and
          vi.  Notwithstanding any other provision herein, the Optionee shall
          only be permitted to pay the purchase price with Shares of the
          Company's Common Stock owned by him as of the exercise date in the
          manner and within the time periods allowed under 17 CFR Section
          240.16b-3 promulgated under the Securities Exchange Act of 1934, as
          amended ("Exchange Act"), as such regulation is presently constituted,
          as it is amended from time to time, and as it is interpreted now or
          hereafter by the Securities and Exchange Commission.

6.   ADJUSTMENTS UPON CHANGES IN CAPITALIZATION OR MERGER.
The number of Shares covered by this Option shall be adjusted in accordance with
the provisions of Section 11 of the Plan in the event of changes in the
capitalization or organization of the Company, or if the Company is a party to a
merger or other corporate reorganization.

7.   TERM OF OPTION
This Option may not be exercised more than six (6) years from the date of grant
of this Option, as set forth below, and may be exercised during such term only
in accordance with the Plan and the terms of this Option.

8.   NOT EMPLOYMENT CONTRACT
Nothing in this Agreement or in the Plan shall confer upon the Optionee any
right to continue in the employ of the Company or shall interfere with or
restrict in any way the rights of the Company, which are hereby expressly
reserved, to discharge the Optionee at any time for any reason whatsoever, with
or without cause, subject to the provisions of applicable law.  This is not an
employment contract.

9.   INCOME TAX WITHHOLDING
a.   The Optionee authorizes the Company to withhold in accordance with
applicable law from any compensation payable to him or her any taxes required to
be withheld by Federal, state or local laws as a result of the exercise of this
Option.  The Optionee agrees to notify the Company immediately in the event of
any disqualifying disposition (within the meaning of Section 421(b) of the Code)
of the shares acquired upon exercise of an incentive stock option.  Furthermore,
in the event of any determination that the Company has failed to withhold a sum
sufficient to pay all withholding taxes due in connection with the exercise of
this Option, or a disqualifying disposition of the shares acquired upon exercise
of an incentive stock option, the Optionee agrees to pay the Company the amount
of such deficiency in cash within five (5) days after receiving a written demand
from the Company to do so, whether or not Optionee is an employee of the Company
at that time.
b.   At such time as the Optionee is required to pay to the Company an amount
with respect to tax withholding obligations as set forth in subparagraph a, the
Optionee may elect prior to the date the amount of such withholding tax is
determined to make such payment, or such increased payment as the Optionee
elects to make up to the maximum federal, state and local marginal tax rates
(including any related FICA obligation) applicable to the Optionee and the
particular transaction in accordance with the provisions of Section 9.g of the
Plan.
c.   Any adverse consequences incurred by an Optionee with respect to the use of
shares of Common Stock to pay any part of the Option Price or of any tax in
connection with the exercise of an Option, including, without limitation, any
adverse tax consequences arising as a result of a disqualifying disposition
within the meaning of Section 422 of the Code, shall be the sole responsibility
of the Optionee.

     remit payment for) the purchase price of the shares being purchased on or

     Stock on the date of exercise, by surrender of shares of the Company's
     Common Stock, provided that if such shares were acquired upon exercise of
     an incentive stock option, the Optionee must have first satisfied the

          the securities laws of any other state, or an opinion of counsel for
          the Company or Optionee that such transfer may be effected under

Optionee understands that, upon exercise of this Option, he will recognize
income for tax purposes in an amount equal to the excess of the then fair market
value of the Shares purchased over the exercise price paid for such Shares. 
(Since the Optionee is subject to Section 16(b) of the Exchange Act, the
measurement and timing of such income may be deferred under certain
circumstances, and the Optionee is advised to contact a tax advisor concerning
the desirability of filing an 83(b) election in connection with the exercise of
the Option.)  Upon a resale of such Shares by the Optionee, any difference
between the sale price and the fair market value of the Shares on the date of
exercise of the Option to the extent not included in income as described above,
will be treated as capital gain or loss.

<TABLE>
<CAPTION>
               PARTNERSHIP       PERCENTAGE
               <S>               <C>      
                 MWP              24.25529%
                 MWP I            19.01593%
                 MWP II           53.87997%
                 MWP III           2.84881%
</TABLE>

          (b) At or prior to the Closing, the Operating Partnerships may obtain
          new loans or refinance existing debt of the Constituent Partnerships,
          which will be, or is secured by, certain Existing Properties and/or
          Contributed Properties. The amount of debt encumbering such Properties
          will affect the value of each of the Constituent Partnerships and the
          percentage of the total Contribution Amount allowable to each such
          Partnership.  Accordingly,  the parties agree that  proportional
          adjustments will be made in the percentages set forth in the table in
          Section 3(a) to reflect the difference  between the amount of
          indebtedness for borrowed funds which encumbers the Properties of a

<PAGE>

          Constituent Partnership as of the Closing Date and the amount of such
          indebtedness as of the date of this Agreement. Furthermore, the
          parties acknowledge and agree that for income tax purposes, limited
          partners in the Operating Partnership, and the partners or other
          equity owners in such limited partners have assumed or guaranteed, or
          will wish to assume or guaranty certain indebtedness of their
          respective Constituent Partnerships. All parties acknowledge and agree
          that all limited partners or owners of interests therein shall be
          entitled to assume or guaranty  indebtedness  of the Operating
          Partnership as of the Closing Date in such proportions as they
          request.

     5.4 ADDITIONAL CONDITIONS WITH RESPECT TO THE CONTRIBUTED PROPERTIES. The
     obligations  of the Company and the parties hereto other than the
     Contributing Entities to effect the Closing with respect to the acquisition
     of the Contributed Properties shall be subject to the satisfaction of the

     Contributing  Entities  with respect to its  particular  Contributed
     Property(ies):

          (a) Title to its Contributed Properties shall be such as will be
          insured, solely in the name of the appropriate Contributing Entity as
          good and marketable by a national title insurance company (the "Title
          Insurance  Company") at regular rates pursuant to the standard
          stipulations and conditions of the 1970 Form B ALTA Owner's Title
          Insurance Policy as revised in 1984 and as the same may be modified by

          Contributing Entity shall deliver to the Title Insurance Company such
          commercially reasonable instruments as the Title Insurance Company
          requires to issue endorsements and other coverages, in such form as

          insurance shall be borne by the Operating Partnership.

          financing statements filed with the Secretary of State and/or county
          clerk against its Contributed Properties, together with bankruptcy,
          tax lien and judgment searches and searches for pending litigation in
          all appropriate jurisdictions. It is a condition of Closing that such
          searches reveal that other than the Permitted Encumbrances there are
          no bankruptcies, actions, claims or liens affecting or encumbering or
          which might affect or encumber its Contributed Properties or any
          interest in its Contributed Properties which will continue after the
          Closing Date.

          acceptable to the Company obtained from lessors under any ground lease
          under which a Contributing Entity is a lessee.

          available, of all Leases and amendments thereto and guarantees
          thereof, all ground leases and all mortgages and related documents
          relating to its Contributed Properties directly to the Operating
          Partnership.

          (suitable for reproduction) to tenants advising of the transfer of the
          Contributed Property to the Operating Partnership and advising the
          tenants to pay all future rentals to or upon the order of the
          Operating Partnership.

          (g) The Contributing Entity shall have delivered to the Operating
          Partnership, all Security Deposits, together with all interest earned
          thereon as of the Closing Date which the Contributing Entity is
          obligated, by law, contract or otherwise, to pay to tenants with
          respect to its Contributed Properties.

          (h) The Contributing Entity shall have delivered directly to the
          Company,  copies of building plans and  specifications for its
          Contributed Properties, if available.

          (i) The Contributing Entity shall have delivered directly to the
          Company, the following, to the extent in the possession of the
          Contributing  Entity:  copies of all certificates of occupancy,

<PAGE>

          with proof of payment thereof (if any of the same have been paid), for
          current real estate and personal property taxes.

          (j) Each of the Contributing Entities shall have delivered to the
          Company, a Non-Foreign Transferor Certificate, certifying that such
          the Contributing Entity is not a "foreign person" within the meaning
          of Section 1445 of the Internal Revenue Code of 1986, as amended (the
          "Code").

          (k) The Contributing Entity shall have executed and delivered to the
          Company such other documents or instruments as in the reasonable
          opinion of counsel for the Company may be necessary to effectuate the
          transactions described in this Agreement, provided that such documents
          or instruments do not increase the liability of the Contributing
          Entities.

          have been or will be made available to the Company, are complete and
          correct, have been maintained in accordance with sound business
          practices and fairly reflect the assets, liabilities and operations of
          the Contributing Entity and the aforesaid financial statements are in
          conformity therewith.

     6.13 ABSENCE OF CERTAIN CHANGES OR EVENTS. Since December 31, 1997, the
     business of the Contributing Entity has been conducted in the ordinary
     course and, except as shall be set forth on Schedule 6.13, the Contributing

          other representative of the Contributing Entity;

          (f) amended any material contract, Lease or agreement;

          (g) entered into any agreement resulting in the imposition of any

          absolute or contingent, except in the ordinary course of business or

          Agreement or in the Schedules delivered pursuant hereto.

     6.14 SUITABILITY. Each of the partners in the Constituent Partnerships and
     each of the Contributing Entities is an "accredited investor," or is
     represented by a "purchaser representative," as defined in Rule 501 of
     Regulation D promulgated under the Securities Act.

     6.15 INVESTMENT. Each of the partners in the Constituent Partnerships and
     each of the Contributing Entities is acquiring the L.P. Units for
     investment for such party's own account and not with a view to, or for
     resale, in connection with, any distribution of the L.P. Units, and such
     party has no present intention of selling or distributing any of such L.P.
     Units. Each of the partners in the Constituent Partnerships and each of the
     Contributing Entities understands that the L.P. Units have not been
     registered under the Securities Act by reason of a specific exemption from
     the registration provisions of the Securities Act which depends upon, among
     other things, the BONA FIDE nature of the party's investment intent as
     expressed herein.

     6.16 RULE 144. Each of the partners in the Constituent Partnerships and
     each of the Contributing Entities acknowledges that, because they have not
     been registered under the Securities Act, the L.P. Units constitute
     "restricted securities" as defined in Rule 144(a)(3) and must be held
     indefinitely unless subsequently registered under the Securities Act or an
     exemption from such registration is available. Each of the partners in the
     Constituent Partnerships and each of the Contributing Entities is aware of
     the provisions of Rule 144 promulgated under the Securities Act which
     permit limited resale of securities purchased in a private placement
     subject to the satisfaction of certain conditions, including, among other
     things, the existence of a public market for the securities, the
     availability of certain current public information about the issuer, the
     resale occurring not less than one year after a party has purchased and
     paid for the security to be sold, the sale being through a "broker's
     transaction" or in transactions directly with a "market maker" (as provided
     by Rule 144(f)) and the number of securities being sold during any
     three-month period not exceeding  specified  limitations (unless the
     securities satisfy the requirements of Rule 144(k)).

Operating Partnership, severally and for itself with respect only to the

     7.1 TITLE TO PREMISES.

          (a) The Owner has not done or suffered or permitted to be done or
          committed any act or matter which would render legal and equitable

          insured as such by the Title Insurance Company, as specified in
          Section 5.4(a), subject only to the Permitted Encumbrances and the
          Leases.

          (b) There has been no violation by the Owner or its Properties of any
          provision, condition or agreement contained in any restrictive
          covenant, cross-easement agreement or similar instrument or agreement
          affecting its Properties or any portion thereof, which would have a
          material adverse effect on its Properties.

          (c) The Personal Property located on its Properties, other than that
          owned by tenants, utility companies or contractors is owned or leased
          by the Owner, includes all the types and approximate quantities of
          personal property heretofore owned or leased by the Owner and used in
          the ownership, operation and maintenance of the improvements located
          on its Properties and, if owned or leased by the Owner, as of the
          Closing Date, is owned or leased by the Owner free and clear of any
          liens or security interests of any kind, except for Permitted
          Encumbrances.

          (d) Its Properties are an independent unit which does not now rely on
          any  facilities (other than facilities covered by Permitted
          Encumbrances including, without limitation, any reciprocal easement
          agreements, or facilities of municipalities or public utility and
          water companies and other than parking areas which its Properties make
          legal use of under any reciprocal easement agreements) located on any
          property not included in its Properties to fulfill any requirement of
          any Governmental Body or for the furnishing to its Properties of any
          essential building systems or utilities.

          (e) Except as may be contained in the Leases, there are no purchase
          contracts, options, or any other agreements of any kind, written or
          oral, recorded or unrecorded, whereby any person or entity other than
          the Owner has or will have any basis to assert any right, title or
          interest in, or right to possession, use, enjoyment or proceeds of all
          or a portion of its Properties.

     7.2 LEASES.

          (a) Except for the Leases of its Properties to be set forth on
          Schedule 7.2(a), the Owner has not entered into any other contracts
          for the sale or leasing of its Properties or any portion thereof.

          (b) As of the Closing Date, no persons or entities, other than the
          Owner and the tenants under the Leases and their permitted subtenants

<PAGE>

          and licensees, shall have any right to the possession, use or
          occupancy of its Properties or any portion thereof for any reason
          whatsoever.

          (c) As of the Closing Date, Schedule 7.2(c) (the "Rent Roll") will be
          true and correct in all material respects as of the date noted thereon
          and discloses all Leases and the rents due for the dates shown thereon
          (collectively, "Rents"). The Leases include all tenancies, licenses
          and subleases and other rights of occupancy or use for all or any
          portion of its Properties pursuant to which the Owner is landlord or
          licensor, all as amended, renewed and extended to the date of the Rent
          Roll, whether oral or written.

          (d) As of the Closing Date, Schedule 7.2(d) will contain a list of all
          security deposits given by the lessees under the Leases (the "Security
          Deposits"). Each Security Deposit has been and is held by the Owner or
          its agents in compliance with the respective Lease and applicable law.
          There are no unfulfilled obligations as to Security Deposits to
          tenants under Leases the terms of which have expired or been
          terminated and there is no suit, action or other claim made, or, to
          the knowledge of the Owner, pending or threatened with respect to any
          such Security Deposit.

               (i) the Lease is valid and existing and in full force and effect
               in accordance with its terms. No Lease has been modified, in

               (iii) except for delinquencies in payment of rent of less than
               thirty (30) days, to the knowledge of the Owner there has been no
               material default or event which, with the giving of notice or the
               lapse of time, or both, would constitute a default, on the part
               of the lessor thereunder and, the tenant has not asserted and, to
               the knowledge of the Owner, has no defense to or offset or claim
               against its rent or the performance of its other obligations
               under the Lease;

               (iv) no tenant has prepaid any rent for more than one month if
               the lease term has commenced and two months if the lease term has
               not yet commenced;

               (v) the Owner has received no written notice from any tenant or
               any guarantor of a Lease that such tenant or guarantor is or may

               material obligations under the Lease;

               (vi) the Owner has not, and to the knowledge of the Owner, no
               other person has, released or discharged any guarantor,
               voluntarily or involuntarily or by operation of law, from any

<PAGE>

               obligation with respect to the Lease that such guarantor has
               guaranteed;

               (vii) at the time of Closing, no rents will have been assigned,
               pledged or encumbered;

               (viii) except as shall be set forth on Schedule 7.2(a) as of the
               Closing Date, the Owner does not own, directly or indirectly, (A)

               paid, and there is no on-going work with respect to any tenant
               improvement.

     knowledge of the Owner, no other person or entity has done anything to

     accordance with all applicable laws or used by tenants of its Properties in

     comply with, at all times, any applicable Environmental Laws (as hereafter
     defined) or any other governmental law, regulation or requirement relating
     to environmental and occupational health and safety matters and Hazardous

     foregoing sentence and all federal, state and local environmental health
     and safety statutes, ordinances, codes, rules, regulations, orders and
     decrees regulating, relating to or imposing liability or standards
     concerning or in connection with Hazardous Materials. The term
     "Environmental Claim" shall mean any administrative, regulatory or judicial

          conditioning, plumbing, electrical, drainage, fire alarm,
          communications, sprinkler, security and exhaust systems are in
          operational and working order and such systems do not contain any
          material hidden defect.

          (b) The Owner has no knowledge that the flood hazard area designation
          for its Properties as shown on a survey of its Properties is
          incorrect.

          its Properties at regular rates and fees, or (B) could result in the
          discontinuance of such services presently available or necessary.
          Water and sanitary sewer provided for its Properties are public.

     7.5 FINANCIAL MATTERS.

          (a) All alterations, improvements or other work required to have been
          completed by the Owner under any reciprocal easement agreements,
          Leases executed prior to the Closing Date, and other agreements to
          which it is a party, including, without limitation, all alterations,
          improvements and other work or allowances therefor required to prepare
          space for the initial occupancy of each tenant under a lease, has
          heretofore been completed and/or paid for in full.

          (b) Except as may be set forth on Schedule 7.5(b) as of the Closing
          Date, there is no income derived from the Owner's Properties other
          than rental income and interest income. The rental income derived from
          its Properties constitutes "rent from real property" as defined in
          Section 856(d)(1) of the Code. The interest income derived from the
          operation of its Properties constitutes "interest" as defined in
          Section 856(c)(2)(B) of the Code.

     7.6 INSURANCE.

          (a) As of the Closing Date, Schedule 7.6 shall set forth an accurate
          and complete list of the insurance policies relating to its Properties
          or any part thereof and naming the Owner as an insured; all such
          policies are in full force and effect and all premiums thereunder as
          of the Closing Date have been paid to the extent due; and no notice of
          cancellation has been received with respect thereto and, to the
          knowledge of the Owner, none is threatened. The Owner represents that
          it does not currently self-insure with respect to any portion of the
          insurance, other than earthquake insurance.

          (b) The Owner has not received any notice from any insurance company
          of any defect or inaccuracies in any of its Properties, or any parts
          thereof, which would adversely affect the insurability of any of its
          Properties, or would increase the cost of insurance beyond that which
          would ordinarily and customarily be charged for similar properties in
          the vicinity of such Properties. All of its Properties are fully
          insured in accordance with prudent and customary practice.

          (c) To the knowledge of the Owner, the Owner has complied with all
          work orders, requirements and demands of each and every insurance
          company insuring all or any part of its Properties.

     7.7 REAL ESTATE TAXES AND ASSESSMENTS.

          (a) The copies of the real property tax bills for its Properties for
          the current tax year which have been furnished by the Owner to the
          Operating Partnership are true and correct and complete copies of all
          of such tax bills. All real estate taxes due and payable as of the
          Closing Date have been paid in full and there are no pending or, to
          the knowledge of the Owner, threatened proceedings for the correction
          or reduction of the assessed valuation of its Properties for the
          current or prior tax years.

<PAGE>

          (b) Each of its Properties alone constitutes one or more entire tax
          parcel(s) for real estate tax purposes, and are not taxed as part of a
          larger tax parcel.

          (c) The Owner has not received notice that, and to the knowledge of
          the Owner, there are no public improvements in the nature of off-site
          improvements, or otherwise, which have been ordered to be made and/or
          which have not heretofore been assessed and there are no special or
          general assessments (other than regular, annual real estate taxes)
          pending against or presently being considered in formal municipal or
          quasi-municipal proceedings which will affect its Properties.

     7.8 CONDEMNATION; COMPLIANCE WITH LAWS, ETC.

          (a) The Owner has not received any written notice with respect to its
          Properties from any public authority concerning any eminent domain or
          condemnation proceeding, or any uncorrected violation of any
          ordinance, public regulation, statute, permit, site plan approval,
          zoning or subdivision regulation or urban redevelopment plan
          applicable to its Properties.

          (b) To the knowledge of the Owner, its Properties, when built, did not
          violate any federal, state, county or municipal laws, ordinances,
          codes, regulations or requirements affecting all or any of its
          Properties including, without limitation, housing, building, safety,
          health, environmental, fire or zoning ordinances, codes and
          regulations of the respective jurisdictions within which its
          Properties are located (together, "Applicable Laws").

          (c) To the knowledge of the Owner, there are no material unperformed
          obligations relative to its Properties outstanding pursuant to any
          written agreements with any Governmental Body.

          circumstances in which they were made, not misleading.

     8.6 INDEMNIFICATION AND INSURANCE.

          (a) In the event of any threatened or actual claim, action, suit,
          proceeding or investigation, whether civil, criminal or
          administrative, including, without limitation, any such claim, action,
          suit, proceeding or investigation in which any of the present officers
          or directors of the Company is, or is threatened to be, made a party
          by reason of the fact that he is or was a director, officer, employee
          or agent of the Company, or is or was serving at the request of the
          Company as a trustee, director, officer, employee or agent of another
          corporation, partnership, joint venture, trust or other enterprise,
          whether before or after the Closing, the Company shall use its best
          efforts to defend against such claim, action, fact, proceeding or
          investigation and to respond promptly thereto. It is understood and
          agreed that the Company shall indemnify and hold harmless, as and to
          the full extent permitted by applicable law, each such officer or
          director against any losses, claims, damages, liabilities, costs,
          expenses (including attorneys' fees), judgments, fines and amounts
          paid in settlement in connection with any such claim, action, suit,
          proceeding or investigation, and in the event of any such claim,
          action, suit, proceeding or investigation (whether arising before or
          after the Closing), (i) the Company shall retain counsel reasonably
          satisfactory to the officer or director and shall pay all fees and
          expenses of such counsel for the officer or director promptly as
          statements therefor are received and (ii) the Company will use its
          best efforts to assist in the vigorous defense of any such matter;
          provided that the Company shall not be liable for any settlement
          effected without its prior written consent; and provided further that
          the Company shall have no obligation hereunder to any officer or
          director when and if a court of competent jurisdiction shall
          ultimately determine, and such determination shall have become final
          and non-appealable, that indemnification of such officer or director
          in the manner contemplated hereby is prohibited by applicable law. Any
          officer or director wishing to claim indemnification under this
          Section 8.6(a), upon learning of any such claim, action, suit,
          proceeding or investigation, shall notify the Company thereof.

          of any of the Company's Subsidiaries as in effect as of the date
          hereof with respect to matters occurring prior to the Closing shall
          survive the Closing and shall not be amended in a manner which would

          of time.

          contained in this Agreement to be untrue or inaccurate in any material
          respect at any time from the date of this Agreement to the Closing
          Date (except for changes permitted or contemplated by this Agreement),
          (ii) any failure of such party to comply with or satisfy, in any

          may violate the rights of or confer remedies upon such third party,
          and (iv) any notice of, or other communication relating to, any
          violation of Applicable Laws, any litigation or any order or judgment
          entered or rendered therein.

          to the Company's shareholders and the Closing Date, all parties other

          the information supplied by it or any of its respective Affiliates,
          directors, officers, agents or representatives for inclusion in the
          Proxy Statement/Prospectus.

     practicable, (a) use commercially reasonable efforts to obtain all Required
     Consents, and give all necessary notices to and make all necessary filings
     with and applications and submissions to, any Governmental Body or other

               (ii) It shall operate and manage its Properties in the same

          acquire an equity ownership interest in any entity that has an

          use or which intends to acquire such interests (with the exception of
          investments in the securities of publicly-traded companies, which do
          not represent more than 10% of the outstanding voting securities
          thereof) 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 a committee of the
          Company's Board of Directors comprised solely of Independent
          Directors; PROVIDED, HOWEVER that the foregoing shall not apply to any

          member beneficially owns at least 5% of the outstanding Equity
          interests shall be subject to prior review and approval by the
          Independent Directors Committee. If the proposed transaction or
          contract is not approved by the Independent Directors Committee, at
          least as to the Berg Group member(s)' involvement therein, such Berg
          Group member or members agree not to participate in the transaction or
          enter into such contract. The provisions of this Section 9.2(b) shall

          Partnership, or the Company's shareholders or any other Limited
          Partners not to (i) engage in the same or similar activities or lines
          of business as the Company, (ii) invest or own any interest publicly
          or privately in, or develop a business relationship with, any
          corporation, partnership or other entity engaged in the same or
          similar activities or lines of business as, or otherwise in
          competition with, the Company, or (iii) do business with any client or
          customer of the Company. Neither Carl E. Berg nor any other member of
          the Berg Group shall have any obligation, or be liable, to the
          Company, or the Operating Partnership (A) for or arising out of the
          conduct described in (i), (ii), or (iii), above, (B) for exercising or
          failing to exercise his or the Berg Group's rights under this
          Agreement or any other Related Agreement to which he or they will be a
          party, (C) for exercising or failing to exercise his or the Berg
          Group's rights as a shareholder of the Company or as a Limited
          Partner, (D) for breach of any fiduciary or other duty to the Company,
          or the Operating Partnership by reason of the conduct described in
          (A), (B) or (C) above. Except as provided otherwise in Section 9.2(a)
          or (b), in the event that any member of the Berg Group, acquires
          knowledge of a potential transaction, agreement, arrangement or other
          matter which may be a corporate opportunity for both such Person and
          the Company, neither such Person nor its officers, directors,
          employees or former employees shall have any duty to communicate or
          offer such corporate opportunity to the Company, and neither such
          Person nor its officers, directors, employees or former employees
          shall be liable to the Company for breach of any fiduciary or other
          duty, as a shareholder or otherwise, by reason of the fact that such
          Person pursues or acquires such corporate opportunity for itself,
          directs such corporate opportunity to another Person or does not
          communicate such corporate opportunity or information regarding such
          corporate opportunity to the Company.

     9.3 RIGHT OF FIRST REFUSAL. The Company hereby grants to each Limited
     Partner the right of first refusal to purchase his, her or its pro rata
     share of any New Securities (as defined below) that the Company may, from
     time to time, propose to sell and issue. A Limited Partner's pro rata
     share, for purposes of this right of first refusal, is the ratio of the
     number of shares of Common Stock issuable upon exchange of the L.P. Units
     held by such Limited Partner immediately prior to the issuance of New

<PAGE>

     Securities to the total number of shares of Common Stock outstanding
     immediately prior to the issuance of New Securities, assuming conversion or
     exchange of all outstanding securities convertible or exchangeable into
     Common Stock of the company. This right of first refusal shall be subject
     to the following provisions:

          (a) "NEW SECURITIES." "New Securities" shall mean any capital stock of
          the Company, whether or not now authorized, and rights, options or
          warrants to purchase such capital stock, and securities of any type
          whatsoever that are or may become convertible into capital stock;
          provided, however, that the term "New Securities" shall not include
          (i) securities issued pursuant to this Agreement and the Private
          Placement, (ii) securities issued upon exchange of L.P. Units, (iii)
          securities issued pursuant to the acquisition of another business
          entity or business segment of any such entity by the Company by
          merger, purchase of substantially all the assets of such entity or
          business segment or other reorganization whereby the Company or its
          shareholders will own more than fifty percent (50%) of the voting
          power of such business entity or business segment of any such entity,
          (iv) securities issued to officers, directors, employees or
          consultants of or to the Company pursuant to any stock option, stock
          purchase or stock bonus plan, agreement or arrangement approved by the
          board of directors of the Company, (v) securities issued to any
          financial institution in connection with a loan transaction approved
          by the board of directors of the Company, (vi) securities issued to
          vendors or customers or to other persons in similar commercial
          situations with the Company, provided such issuance is approved by the
          board of directors, (vii) securities issued in a public offering
          pursuant to a registration under the Securities Act with an aggregate
          offering price to the public of more than $7,500,000, (viii)
          securities issued in connection with any stock split, stock dividend
          or recapitalization of the Company, and (ix) any right, option or
          warrant to acquire any security convertible into the securities
          excluded from the definition of New Securities pursuant to subsections
          (i) through (viii) above.

          (b) NOTICE OF PROPOSED ISSUANCE. In the event the Company proposes to
          undertake an issuance of New Securities, it shall give each Limited
          Partner written notice of its intention, describing the type of New
          Securities, their price and the general terms upon which the Company
          proposes to issue such New Securities. Each Limited Partner shall have
          ten (10) days after any such notice is mailed or delivered to agree to
          purchase such Limited Partner's pro rata share of such New Securities
          for the price and upon the terms specified in the notice by giving
          written notice to the Company and stating therein the quantity of New
          Securities to be purchased.

          (c) SALE OF NEW SECURITIES. In the event the Limited Partners fail to
          exercise fully the right of first refusal within said ten (10) day
          period, the Company shall have sixty (60) days thereafter to sell or
          enter into an agreement (pursuant to which the sale of New Securities
          covered thereby shall be closed, if at all, within sixty (60) days
          from the date of such agreement) to sell the New Securities respecting
          which the Limited Partners' right of first refusal set forth in this
          Section 9.3 is not exercised, at a price and upon terms no more
          favorable to the purchasers thereof than are specified in the
          Company's notice to Limited Partners pursuant to Section 9.3(b). In

<PAGE>

          the event the Company has not sold the New Securities within the
          foregoing period, the Company shall not thereafter issue or sell any
          New Securities without first again offering such securities to the
          Limited Partners in the manner provided in Section 9.3 (b) above.

          (d) ASSIGNMENT. The rights granted by the Company pursuant to this
          Section 9.3 may be assigned by any Limited Partner to a transferee or
          assignee of not less than 500,000 L.P. Units (as adjusted for stock
          splits, combinations and the like), provided that such assignment may
          otherwise be effected in accordance with applicable securities laws
          and that the Company is given written notice at the time of said
          assignment stating the name and address of said transferee or assignee
          and identifying the securities with respect to which such rights are
          being assigned.

          (e) TERMINATION OF RIGHT OF FIRST REFUSAL. The right of first refusal
          granted under this Section 9.3 shall terminate upon the earlier of (i)
          May 14, 2003 or (ii) written agreement of the Company and the holders
          of a majority of the L.P. Units then outstanding.

     9.4 REIT ELECTION. After the Closing, the Company agrees to take all action
     necessary to qualify as a REIT and to make an election to be taxed as a
     REIT in the tax year ending December 31, 1998.

     9.5 BERG GROUP BOARD REPRESENTATIVES; REQUIRED DIRECTORS CONSENT; SUPER
     MAJORITY APPROVAL. The Company agrees that the Berg Group will have the
     right to nominate two directors for election to the board of directors so
     long as the Berg Group members together with their Affiliates (other than
     the Company and the Operating Partnership) own at least 15% of the Equity
     Securities of the Company treating all L.P. Units owned by such members and
     their Affiliates as Common Stock for this purpose, and the right to
     nominate one director if such ownership interest is less than 15% but at
     least 10% of such Equity Securities. The Company agrees to take all steps
     necessary to cause the election of such Berg Group nominees to the board of
     directors.  The Company agrees that until the Protective Provisions
     Expiration Date it will not take or permit to be taken any of the following
     actions without the approval of the Required Directors (in addition to all
     other approvals required by the Company's articles of incorporation,
     bylaws, contracts or applicable law): (i) establishing a quorum for any
     meeting of the board of directors which is not attended by a Required
     Director; (ii) amending the Company's articles of incorporation or bylaws;
     (iii) merging the Company with or into any other Entity; or (iv) any sale
     of all or substantially all of the Company's assets. The Company agrees
     further, and the bylaws of Mission West-Maryland shall provide following
     the Reincorporation Merger 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 Partnership,
     (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.

     9.6 REINCORPORATION MERGER. After the Closing, and subject to Shareholder
     Approval of the Reincorporation Merger, the Company shall take all actions
     and file all documents necessary and shall cause Mission West-Maryland to
     take all actions and file all documents necessary to effectuate the
     Reincorporation Merger. The Company agrees to cause the provisions of
     Sections 9.2 and 9.5 to be incorporated into either the Articles of
     Incorporation or the Bylaws of Mission West-Maryland.

     9.7 OPERATION OF THE OPERATING PARTNERSHIP.

          (a) CASH; DISTRIBUTIONS. The Constituent Partnerships acknowledge and
          agree that from and after the Closing Date, as provided in the
          Operating Partnership Agreement, the Available Cash will be commingled
          and used to pay the obligations of all Constituent Partnerships. In
          addition,  the Operating  Partnership  shall and will make any
          distributions of Available Cash to the Constituent Partnerships on a
          pro rata basis in proportion to the ratio of the number of L.P. Units
          then outstanding in each such limited partnership to the total member
          of L.P. Units then outstanding in the Operating Partnership, and shall
          pay distributions simultaneously to the General Partner of each
          Constituent Partnership in accordance with the General Partner's
          interest in each such limited partnership.  Notwithstanding the
          foregoing, separate books and records shall be maintained for each
          Constituent Partnership,  and all costs shall be accounted for
          separately and properly credited to the general ledger of each
          Constituent Partnership.

          (b) FUTURE OPERATIONS. The Company, as general partner of the
          Operating Partnership, shall make investment, financing and
          operational decisions as though the Operating Partnership was a
          consolidated entity; provided that accounts, books and records shall
          be properly maintained on a separate basis for each Constituent
          Partnership. The Operating Partnership may transact business and
          otherwise act for all of the Constituent Partnerships in the name
          "Mission West Properties, L.P." The Company, as general partner of the
          Operating Partnership, shall endeavor to structure all transactions in
          such manner as will maintain the current pro rata interests of each
          Constituent Partnership, and of the Limited Partners thereof, to the
          Operating Partnership, as a whole, based on the ratio which the
          outstanding L.P. Units of each such limited partnership bears to the
          total number of L.P. Units set forth on Schedule 6.

     9.8 REIT QUALIFICATION OF THE COMPANY. For the purposes of Section
     856(a)(6) and (h) of the Code, the Berg Group members agree that they shall
     not own (within the meaning of Section 544(a) of the Code), both
     individually and as a group, more than 20% of the total value of the
     Company's outstanding stock (as determined for purposes of Section
     542(a)(2) of the Code) (the "Berg Ownership Limit"); and (ii) for purposes
     of all other ownership attribution rules under the Code (in particular
     Section 318 of the Code), no single Berg Group member shall directly or
     indirectly own 50% or more of the value of the Company's outstanding stock.
     The Berg Group members further agree that at no time while the Company is a
     REIT shall they acquire or permit any person within their control to
     acquire shares of Common Stock or other Equity Securities of the Company if
     such acquisition would cause the Company to fail to satisfy the REIT
     requirement that five or fewer individuals cannot own more than 50% of the
     value of the Company's outstanding stock within the meaning of Sections
     544(a)(2) and Section 856(a)(6) and (h) of the Code. The Company
     acknowledges and agrees that the right of Limited Partners to exchange L.P.
     Units for Common Stock pursuant to the Exchange Rights Agreement does not
     constitute the ownership of stock by such Limited Partners under Section
     544(a) or 318 of the Code.

10.   SURVIVAL OF REPRESENTATIONS AND WARRANTIES; INDEMNIFICATION.

<PAGE>

     10.1 SURVIVAL. All representations, warranties and agreements contained in
     this Agreement or in any certificate delivered pursuant to this Agreement
     shall survive the Closing for a period of one year.

     10.2 INDEMNIFICATION. Each party to this Agreement shall severally
     indemnify and hold harmless all other parties and their Affiliates, for any
     loss, liability, claim, damage, expense (including, but not limited to,
     costs of investigation and defense and reasonable attorneys' fees) or
     diminution of value (collectively, "Damages") arising from or in connection
     with (a) any inaccuracy in any of the representations and warranties of
     such party in this Agreement, (b) any failure by such party to perform or
     comply with any covenant, obligation or agreement in this Agreement, (c)
     any liabilities of such party not specifically assumed by the Operating
     Partnership or the Company hereunder, (d) any claim by any Person for
     brokerage or finder's fees or commissions or similar payments based upon
     any agreement or understanding alleged to have been made by any such Person
     with such party (or any Person acting on such party's behalf) in connection
     with any of the Proposed Transactions.

     10.3 PROCEDURE FOR INDEMNIFICATION. Promptly after receipt by an
     indemnified party ("Indemnified Party") under Section 10.2 of notice of the
     commencement of any action, such Indemnified Party shall, if a claim in
     respect thereof is to be made against an indemnifying party ("Indemnifying
     Party") under such section, give notice to the Indemnifying Party of the
     commencement thereof, but the failure so to notify the Indemnifying Party
     shall not relieve it of any liability that it may have to any Indemnified
     Party except to the extent the Indemnifying Party demonstrates that the
     defense of such action is prejudiced thereby. In case any such action shall
     be brought against an Indemnified Party and it shall give notice to the
     Indemnifying Party of the commencement thereof, the Indemnifying Party
     shall be entitled to participate therein and, to the extent that it shall
     wish, to assume the defense thereof with counsel reasonably satisfactory to
     such Indemnified Party and, after notice from the Indemnifying Party to
     such Indemnified Party of its election so to assume the defense thereof,
     the Indemnifying Party shall not be liable to such Indemnified Party under
     such section for any fees of other counsel or any other expenses, in each
     case subsequently incurred by such Indemnified Party in connection with the
     defense thereof, other than reasonable costs of investigation. If an
     Indemnifying Party assumes the defense of such an action, (a) no compromise
     or settlement thereof may be effected by the Indemnifying Party without the
     Indemnified Party's consent unless (i) there is no finding or admission of
     any violation of law or any violation of the rights of any Person and no
     effect on any other claims that may be made against the Indemnified Party
     and (ii) the sole relief provided is monetary damages that are paid in full
     by the Indemnifying Party and (b) the Indemnifying Party shall have no
     liability with respect to any compromise or settlement thereof effected
     without its consent (which consent will not be unreasonably withheld). If
     notice is given to an Indemnifying Party of the commencement of any action
     and it does not, within ten (10) days after the Indemnified Party's notice
     is given, give notice to the Indemnified Party of its election to assume
     the defense thereof, the Indemnifying Party shall be bound by any
     determination made in such action or any compromise or settlement thereof
     effected by the Indemnified Party. Notwithstanding the foregoing, if an
     Indemnified Party determines in good faith that there is a reasonable
     probability that an action may adversely affect it or its affiliates other
     than as a result of monetary damages, such Indemnified Party may, by notice

<PAGE>

     to the Indemnifying Party, assume the exclusive right to defend, compromise
     or settle such action, but the Indemnifying Party shall not be bound by any
     determination of an action so defended or any compromise or settlement
     thereof effected without its consent (which consent shall not be
     unreasonably withheld). Notwithstanding the foregoing, any determination
     with respect to the Company's determination to make a claim for
     indemnification against the Contributing Entities shall be made solely by a
     majority of the Independent Directors.

11.   TERMINATION.

     11.1 TERMINATION.

          (a) This Agreement may be terminated by the Company or by Carl E. Berg
          before the Closing occurs, whether before or after the Shareholder
          Meeting, only as follows:

               (i) if the consummation of the Proposed Transactions by the
               Company would violate any non-appealable final order, decree or
               judgment of any Governmental Body having competent jurisdiction;

               (ii) if any material representation or warranty of the Operating
               Partnership or any of the Contributing Entities or the
               Constituent Partnerships made herein is untrue in any material
               respect (other than a change permitted or contemplated by this
               Agreement) and such breach is not cured within 60 days of receipt
               of a notice from the Company that such breach exists or has
               occurred;

               (iii) if the conditions to the Company's obligations to 
               consummate the Closing as set forth in Sections 5.3 and 5.4 
               cannot reasonably be satisfied on or before September 30, 1998;

               (iv) if the Company's shareholders do not approve the Private
               Placements and the Berg Acquisition at the Special Meeting.

          (b) This Agreement may be terminated by the Company alone if any
          consent of any Limited Partner other than a Limited Partner who is a
          member of the Berg Group shall not have been obtained on or before the
          Closing Date.

     11.2 EFFECT OF TERMINATION. In the event that this Agreement is terminated
     pursuant to Section 11.1, this Agreement shall terminate without any
     liability or further obligation of any party to another, except for
     Sections 8.6, 10.2, and 10.3 which shall survive termination. A termination
     under Section 11.1 shall not relieve a defaulting or breaching party (or
     any party who has liability under this Agreement in respect of the actions
     of a defaulting or breaching party) from any liability to the other party
     or parties hereto for or in respect of such default or breach.

12.   NOTICES.

     All notices, consents and other communications under this agreement shall
     be in writing and shall be deemed to have been duly given when (a)
     delivered by hand, (b) sent by facsimile transmission (with receipt
     confirmed), provided that a copy is mailed by registered mail, return
     receipt requested, or (c) when received by the addressee, if sent by

<PAGE>

     Express Mail, Federal Express or other express delivery service (receipt
     requested), in each case to the appropriate addresses, and telecopier
     numbers set forth in Appendix I hereto (or to such other addresses, and fax
     numbers as a party may designate as to itself by notice to the other
     parties).

13.   GOVERNING LAW; JURISDICTION; ETC.

     13.1 GOVERNING LAW. This Agreement and (unless otherwise provided) all
     amendments hereof and waivers and consents hereunder shall be governed by
     the internal laws of the State of California, without regard to the
     conflicts of law principles thereof.

     13.2 JURISDICTION. Any action or proceeding seeking to enforce any
     provision of, or based on any right arising out of, this agreement may be
     brought against any of the parties in the courts of the State of
     California, or, if it has or can acquire jurisdiction, in the Northern
     District of California, and each of the parties hereby consents to the
     jurisdiction of such courts (and of the appropriate appellate courts) in
     any such action or proceeding and waives any objection to venue laid
     therein.

14.   MISCELLANEOUS.

     14.1 SPECIFIC PERFORMANCE. The parties acknowledge that the subject matter
     of this Agreement is unique and that no adequate remedy of law would be
     available for breach of this Agreement. Accordingly, each party agrees that
     the other parties will be entitled to an appropriate decree of specific
     performance or other equitable remedies to enforce this Agreement (without
     any bond or other security being required) and each party waives the
     defense in any action or proceeding brought to enforce this Agreement that
     there exists an adequate remedy at law.

     14.2 CAPTIONS. The captions or headings of the Sections of this Agreement
     are for convenience only, and shall not control or affect the meaning or
     construction of any of the terms or provisions of this Agreement.
     References in this Agreement to Sections are references to Sections of this
     Agreement, unless expressly stated to the contrary. References in this
     Agreement to Schedules are, unless expressly stated to the contrary,
     references to Schedules to this Agreement, each of which is part of this
     Agreement.

     14.3 NO WAIVER. The failure of a party to insist upon strict adherence to
     any term of this Agreement on any occasion shall not be considered a waiver
     or deprive that party of the right thereafter to insist upon strict
     adherence to that term or any other term of this Agreement. Any waiver must
     be in writing.

     14.4 ENTIRE AGREEMENT; AMENDMENT. This Agreement supersedes all prior
     agreements among the parties with respect to its subject matter, and is
     intended (with the documents referred to herein) as a complete and
     exclusive statement of the terms of the agreement among the parties with
     respect thereto and cannot be changed or terminated except by a written
     instrument executed by the party or parties against whom enforcement
     thereof is sought. This Agreement shall bind and inure to the benefit of
     the parties hereto and their respective heirs, executors,  personal
     representatives, successors and assigns.

<PAGE>

     14.5 BINDING NATURE. This Agreement shall be binding on each party hereto
     at the time that such party executes this Agreement notwithstanding that
     other signatories hereto executed and delivered the Agreement at a later
     date or not at all.

     14.6 COUNTERPARTS. This Agreement may be executed in counterparts and
     delivered by electronic facsimile transmission, and each signed counterpart
     transmitted by electronic facsimile shall be considered an original, but
     all of which together shall constitute the same instrument.

            principal), by grant deed to MWP; MWP III shall elect to become a

            upon the representations, warranties, and agreements contained
            herein, at the Partnership Closing, the Operating Partnership shall

            3.3 THE BERG ACQUISITION.

<PAGE>

            (a) Subject to the terms and conditions hereof and in reliance upon
            the representations, warranties, and agreements contained herein, at
            the Partnership Closing: (i) the Company shall acquire the general
            partnership interests in each of the Constituent Partnerships for
            the total amount of Thirty-Three Million Five Hundred Eighty-Nine
            Thousand Three Hundred Thirty-Three Dollars ($33,589,333) payable by
            delivery of a demand note ("Demand Note") to each of the Constituent
            Partnerships in the amounts set forth opposite the name of such
            Constituent Partnership (the "Contribution Amount") in the form
            attached hereto Exhibit G; (ii) Berg & Berg Enterprises, Inc., Berg
            Family Partners LLC, Berg & Berg Developers LLC, and John T.
            Kontrabecki shall resign as the general partner of MWP, MWP I, MWP
            II, and MWP III, respectively; and (iii) the Company shall receive a
            general partner interest equal to 10.91% of the capital, profits,
            losses and distributions of each Constituent Partnership (or 10.91%
            of the Operating Partnership) in accordance with the terms of the
            Operating Partnership Agreement. The capital contribution and amount
            of the Demand Note payable by the Company set forth below for its
            general partner interest in each of the Constituent Partnerships at
            the Partnership Closing is subject to adjustment as provided in
            Section 3.3(b).

            MWP III                1,002,781
</TABLE>


            (b) At or prior to the Partnership Closing, the Operating
            Partnership may obtain new loans or refinance existing debt of the
            Constituent Partnerships, which will be, or is secured by, certain
            Existing Properties and/or Contributed Properties. The amount of
            debt encumbering such Properties will affect the value of each of
            the Constituent Partnerships and the percentage of the total
            Contribution Amount allocable to each such Partnership. Accordingly,
            the parties agree that appropriate adjustment, if any, will be made
            in the amount of each of the Demand Notes set forth in the table in
            Section 3.3(a) to reflect the difference between the amount of
            indebtedness for borrowed funds which encumbers the Properties of a
            Constituent Partnership as of the Partnership Closing Date and the
            amount of such indebtedness as of the date of this Agreement.
            Furthermore, the parties acknowledge and agree that for income tax
            purposes, limited partners in the Operating Partnership, and the
            partners or other equity owners in such limited partners have
            assumed or guaranteed, or will wish to assume or guaranty certain
            indebtedness of their respective Constituent Partnerships. All
            parties acknowledge and agree that all limited partners or owners of
            interests therein shall be entitled to assume or guaranty
            indebtedness of the Operating Partnership as of the Partnership
            Closing Date and any refinancing date in such proportions as they
            request.

        2.3 THE CLOSING. Sections 4.1-4.3 shall be amended to read in their

<PAGE>

entirety as follows:

            4.1 THE CLOSING DATE.

            Contributing Entities (other than MWP III) at the Partnership

            Partnership Closing by or to the Contributing Entity that owns the
            particular Contributed Property to which the adjustment relates. The
            items to be pro rated as of the Partnership Closing Date include the
            following: real estate taxes (on the basis of the due dates of the
            tax bills for the period for which such taxes are assessed) on the
            Contributed Properties, personal property taxes on the Personal
            Property, minimum water and sewer rentals, rents, including without
            limitation, expense pass-throughs, percentage rents, income from and

            to the Partnership Closing Date under the Leases covering the
            Contributed Properties, payments due under service agreements which
            are to be assigned to the benefit of the Operating Partnership,
            prepaid license fees and other charges for licenses and permits for

            Date, rental under any ground lease, municipal rubbish removal
            charges, lease rejection awards made in any bankruptcy proceedings
            of a tenant, and prepaid insurance premiums for insurance which will
            remain in effect for the benefit of the Operating Partnership after
            the Partnership Closing Date, if any, shall be apportioned pro rata
            between the Contributing Entity and the Operating Partnership, on a
            per diem basis as of midnight on the day before the Partnership
            Closing Date, so that the Contributing Entity shall bear all
            expenses with respect to its Contributed Properties and benefit from
            all items of income with respect to its Contributed Properties
            through the day before the Partnership Closing Date. To the extent
            that the amounts of the items to be adjusted are not reasonably
            ascertainable as of the Partnership Closing Date or there are any
            other items which should properly be allocated at that time, they
            shall be adjusted or taken into account by the affected Contributing
            Entity and the Operating Partnership as promptly after the
            Partnership Closing Date as the amounts thereof are ascertained.

       2.4 CONDITIONS TO CLOSING. Section 5.2 is hereby amended to apply only to
the Partnership Closing as of the Partnership Closing Date. Section 5.2(d) shall
be amended by deleting such provision in its entirety and replacing it with the

            and delivered Demand Notes to the Operating Partnership in the
            aggregate amount of Thirty-Three Million Five Hundred Eighty-nine
            Thousand Three Hundred Thirty-three Dollars ($33,589,733)

interest will be paid in lawful money of the United States of America at the 
address of the Holder of this Note.  All payments on this Note shall be 
applied first to the reduction of any accrued and unpaid interest before any 
reduction in the principal sum outstanding. Notwithstanding the foregoing, 
the Holder shall make no demand under this Note until the earlier of (i) the 
date on which the Maker receives funds from the sale of its equity securities 
in the Private Placement (as identified in the Acquisition Agreement among 
Mission West Properties, Certain Partnerships and the Berg Group (as defined 
therein), dated as of May 14, 1998); and (ii) the second anniversary of the 
issuance of this Note. Any demand by [INSERT NAME OF LIMITED PARTNERSHIP] may 
be made by action of the holders of a majority of the outstanding L.P. Units 
in such partnership.

           The following is a statement of additional rights of the Holder of 
this Note and the conditions to which this Note is subject, to which the 
Holder hereof, by the acceptance of this Note, agrees:

<PAGE>

1. ATTORNEYS' FEES. If the indebtedness represented hereby is not paid in 
full when due, Maker promises to pay all costs of collection, including, but 
not limited to, reasonable attorneys' fees.

2. REPLACEMENT. On receipt of evidence reasonably satisfactory to Maker of 
loss, theft, destruction or mutilation of this Note and, in the case of loss, 
theft or destruction, on delivery of an indemnity agreement or bond 
reasonably satisfactory in form and amount to Maker, or in the case of 
mutilation, on surrender and cancellation of this Note, Maker, at Maker's 
expense, will execute and deliver, in lieu of this Note, a new Note of like 
tenor.

3.  MODIFICATION.  This Note and any of its terms may be changed, waived or 
terminated only by a written instrument signed by the party against which 
enforcement of that change, waiver or termination is sought.

4.  GOVERNING LAW. This Note shall be governed by and construed and enforced 
in accordance with the laws of the State of California.

5. SEVERABILITY.  If any provision of this Note should be found to be invalid 
or unenforceable, all other provisions shall nevertheless remain in full 
force and effect to the maximum extent permitted by law.

6. NOTICES. All notices and other communications required or permitted 
hereunder shall be in writing and shall be deemed effectively given upon 
personal delivery or on the day sent by facsimile transmission if a true and 
correct copy is sent the same day by first class mail, postage prepaid, or by

operations or financial condition of Purchaser.

4.5 BROKERS' FEES.  Except for the fee to be paid to Ingalls & Snyder, no 
investment banker, broker, finder or other intermediary has been retained by 
or is authorized to act on behalf of Purchaser who might be entitled to any 
fee or commission from the Company upon consummation of the transactions 
contemplated

<PAGE>

by this Agreement.

4.6 SUITABILITY.  Purchaser is an "accredited investor," as such term is 
defined in Rule 501 of Regulation D promulgated under the Securities Act.

4.7 INVESTMENT.  Purchaser is acquiring the number of Shares set forth 
opposite Purchaser's name on the Schedule of Purchasers for investment for 
Purchaser's own account and not with a view to, or for, resale in connection 
with, any distribution of the Shares.  Purchaser understands that the Shares 
have not been registered under the Securities Act by reason of a specific 
exemption from the registration provisions of the Securities Act which 
depends upon, among other things, the BONA FIDE nature of Purchaser's 
investment intent as expressed herein.

4.8 RULE 144.  Purchaser acknowledges that, because they have not been 
registered under the Securities Act, the Shares constitute "restricted 
securities" as defined in Rule 144(a)(3) and must be held indefinitely unless 
subsequently registered under the Securities Act or an exemption from such 
registration is available.  Purchaser is aware of the provisions of Rule 144 
promulgated under the Securities Act which permit limited resale of 
securities purchased in a private placement subject to the satisfaction of 
certain conditions, including, among other things, the existence of a public 
market for the securities, the availability of certain current public 
information about the issuer, the resale occurring not less than one year 
after a party has purchased and paid for the security to be sold, the sale 
being through a "broker's transaction" or in transactions directly with a 
"market maker" (as provided by Rule 144(f)) and the number of securities 
being sold during any three-month period not exceeding specified limitations 
(unless the securities satisfy the requirements of Rule 144(k)).

4.9 REIT QUALIFICATION OF THE COMPANY.  For the purposes of Section 856(a)(6) 
and (h) of the Internal Revenue Code of 1986, as amended (the "Code"), each 
Purchaser represents and warrants that upon and as a result of the Purchase's 
acquisition of the Shares at the Closing Date: (i) no individual who is a 
Purchaser or owns a direct or indirect interest in such Purchaser will own 
(within the meaning of Section 544(a) of the Code) more than 10% of the total 
value of the Company's outstanding stock (as determined for purposes of 
Section 542(a)(2) of the Code); (ii) for purposes of the ownership 
attribution rules under Section 856(d)(5) of the Code, Purchaser would not be 
deemed to own 50% or more of the value of the Company's outstanding stock; 
(iii) no Purchaser which is a qualified trust (within the meaning of Section 
856(h)(3)(E) of the Code) will own (within the meaning of Section 544(a) of 
the Code) more than 10% of the value of the outstanding stock of the Company; 
(iv) Purchaser does not own, directly or indirectly, 10% or more of the total 
combined voting power of all classes of stock of any tenant of any of the 
properties listed in the Private Placement Memorandum; and (v) Purchaser has 
no plan or intention, and has not entered into any agreement or arrangement, 
to transfer Shares at any time after the Closing Date such that as a 
consequence of the transfer any of the Purchaser's representations and 
warranties in clauses (i) through (iv) would cease to be true.

5. COVENANTS OF THE COMPANY.

5.1 INVESTIGATION.  Upon reasonable notice, prior to the Closing Date the

      THIS STOCK PURCHASE AGREEMENT (this "Agreement") is made as of the ____ 
day of ________, 1998, by and between the investors identified on Appendix I 
to this Agreement (the "Schedule of Purchasers") (individually a "Purchaser"

                                    RECITALS

      WHEREAS, the Company intends to submit to its shareholders for 
approval: a $26,100,000 investment in the Company by a group of accredited 
investors (the "Ingalls & Snyder Private Placement"); an acquisition by the 
Company of the general partnership interest in four limited partnerships in 
which the limited partners will receive the right to exchange limited partner

pursuant to this Agreement; and the merger of the Company with and into 
Mission West Properties, Inc., a Maryland corporation ("Mission

(the "Reincorporation Merger"), (collectively the "Proposed Transactions");

      WHEREAS, the Company intends to file a Registration  Statement on Form 
S-4 (the "Registration Statement") to register shares of Common Stock and 
other securities to be issued by Mission West-Maryland in exchange for 
securities of the Company pursuant to the Securities Act of 1933, as amended 
(the "Securities Act') and will deliver to the  shareholders  of the Company 
the proxy statement/prospectus included in such Registration Statement in 
connection with the special meeting of shareholders at which the shareholders 
will be asked to approve the purchase and sale of the Shares (the "Special 
Meeting"); and

      WHEREAS, subject to shareholder approval, the Purchasers wish to 
purchase from the Company, and the Company wishes to sell to the Purchasers, 
the Shares pursuant to the terms of the Agreement.

                                    AGREEMENT

      NOW, THEREFORE, the Purchasers and the Company agree as follows:

Purchaser's name on the Schedule of Purchasers.

1.3. SEPARATE AGREEMENTS.  The Company's agreement with each Purchaser is a 
separate agreement, and the sale of the shares of Common Stock to each 
Purchaser is a separate sale.

2.    CLOSING DATE; DELIVERY.

purchase and sale of the Shares hereunder (the "Closing") with each of the 
Purchasers shall be held at the offices of the Company at 10050 Bandley

Stock for issuance under the Company's 1997 Stock Option Plan (the "Plan"), 
of which options to acquire 605,000 shares have been granted and are 
outstanding as of the date hereof. The Company has also reserved Five Million 
Eight Hundred Thousand (5,800,000) shares of Common Stock for issuance 
pursuant to the Ingalls & Snyder Private Placement and has reserved the 
Shares for issuance hereunder. Except for the foregoing, and the other 
securities to be issued in connection with the Proposed Transactions, there 
are no outstanding options, warrants, rights (including conversion or 
preemptive rights) or agreements for the purchase or acquisition from the 
Company of any shares of its capital stock.

of the Company hereunder and thereunder, and the authorization, sale and 
issuance of the Shares pursuant hereto has been taken or will be taken prior 
to the Closing Date. This Agreement, when executed and delivered by the 
Company, will constitute a valid and binding obligation of the Company, 
enforceable in accordance with its terms, except (i) as limited by applicable 
bankruptcy, insolvency, reorganization, moratorium, and other laws of general 
application affecting enforcement of creditors' rights generally, and (ii) as 
limited by laws relating to the availability of specific performance, 
injunctive relief, or other equitable remedies.

3.5. VALID ISSUANCE OF COMMON STOCK.  The Shares that are being purchased by 
the Purchasers hereunder, when issued, sold and delivered in accordance with 
the terms of this Agreement for the consideration expressed herein, will be 
duly and validly issued, fully paid, and nonassessable, and will be free of 
restrictions on transfer other than restrictions on transfer under this 
Agreement, and under applicable state and federal securities laws.

3.6. COMPLIANCE WITH OTHER INSTRUMENTS.  The Company is not in violation or 
default of any term of the Amended and Restated Articles of Incorporation 
(the "Articles"), or Bylaws of the Company, nor is the Company in violation 
or default of any term of any contract, agreement, instrument, judgment, 
decree, order, statute, rule or regulation (collectively, "Instruments and 
Laws") to which the Company is subject and a violation of which would have a 
material adverse effect on the condition, financial or otherwise, or 
operations of the Company. The execution, delivery and performance of this 
Agreement, and the consummation of the transactions pursuant hereto, will not 
result in a violation of or be in conflict with the Articles or the Bylaws of 
the Company or constitute, with or without the passage of time and giving of 
notice, a material default under any such Instrument or Law, except where 
such violations or defaults, singularly or in the aggregate, would not have a 
material adverse effect on the business, operations, property or condition 
(financial or otherwise) of the Company, require any consent or waiver (which 
has not been obtained) under any such Instrument or Law, or result in the 
creation of any lien, encumbrance or charge upon any of the properties or 
assets of the Company pursuant to any such Instrument or Law.

pending or, to the best of the Company's knowledge, threatened against the

with the consummation of the transactions contemplated by this Agreement.

3.9. COMPANY SEC INFORMATION.  As of their respective filing dates (except as 
thereafter amended) all documents that the Company has filed with the SEC 
("Company SEC Documents") have complied in all material respects with the 
applicable requirements of the Securities Exchange Act of 1934, as amended 
(the "Exchange Act"), and none of the Company SEC Documents has contained any 
untrue statement of a material fact or omitted to state a material fact 
required to be stated therein or necessary in order to make the statements 
made therein, in light of the circumstances under which they were made, not 
misleading except to the extent corrected by a subsequently filed Company SEC 
Document.

3.10. OFFERING.  Subject in part to the truth and accuracy of each 
Purchaser's representations set forth in Section 4 of this Agreement, the 
offer, sale and issuance of the Shares as contemplated by this Agreement are 
exempt from the registration requirements under Section 5 of the Securities 
Act, and neither the Company nor any authorized agent acting on its behalf 
will take any action hereafter that would cause the loss of such exemption.

3.11. TITLE TO PROPERTY AND ASSETS.  The Company owns its property and 
assets free and clear of all mortgages, loans, liens and encumbrances, except 
such encumbrances and liens which arise in the ordinary course of business 
and do not materially impair the Company's ownership or use of such property 
or assets. With respect to the property and assets it leases, the Company is 
in compliance with such leases and, to the best of its knowledge, holds a 
valid leasehold interest free of any liens, claims or encumbrances.

ended November 30, 1996 and December 31, 1997 to all Purchasers who have 
requested such information. The Company shall furnish copies of the 
Registration Statement to all Purchasers requesting the same prior to the 
Closing. All of the financial statements set forth in such SEC reports are in 
accordance with the books and records of the Company, have been prepared in 
conformity with generally accepted accounting principles consistently applied 
(except as described in the notes included therein), and fairly present the 
financial condition of the Company as of the dates thereof and the results of 
its operations for the periods then ended, subject, in the case of unaudited 
financial statements, to year-end adjustments.

4. REPRESENTATIONS AND WARRANTIES OF THE PURCHASERS.

Each Purchaser severally represents and warrants to the Company as follows:

4.1 EXISTENCE AND POWER.  Purchaser, if a corporation, partnership or limited

<PAGE>

liability company, is a corporation, partnership or limited liability company 
duly organized, validly existing and in good standing under the laws of the 
state under which it was organized, with full power and authority to enter 
into this Agreement and to perform its obligations under this Agreement.

4.2  AUTHORIZATION.  Purchaser's execution, delivery and performance of this 
Agreement, and the consummation by Purchaser of the transactions contemplated 
by this Agreement have been duly authorized by all requisite corporate, 
partnership or limited liability company action of the Purchaser.

4.3 BINDING EFFECT.  This Agreement has been duly executed and delivered by 
Purchaser, and constitutes a valid and binding agreement of Purchaser.

4.4 CONSENTS AND APPROVALS; NO VIOLATION.  Neither the execution and delivery 
of this Agreement by Purchaser nor the consummation by Purchaser of the 
transactions contemplated hereby will (a) conflict with or result in any 
breach of any provision of the articles of incorporation, bylaws, partnership 
agreement or operating agreement of Purchaser; (b) require any filing with, 
or the obtaining of any permit, authorization, consent or approval of, any 
court or governmental or regulatory authority; (c) to the best knowledge of 
Purchaser, result in a default (give rise to any right of termination, 
cancellation or acceleration) under any of the terms, conditions or 
provisions of any note, bond, mortgage, indenture, license, agreement, lease 
or other instrument or obligation to which Purchaser is a party or by which 
Purchaser or any of its assets may be bound, except for defaults (or rights 
of termination, cancellation or acceleration) as to which requisite waivers 
or consents have been obtained; or (d) to the best knowledge of Purchaser, 
violate any order, writ, injunction, decree, statute, rule or regulation 
applicable to Purchaser; or any of its assets; PROVIDED, that the foregoing 
clauses (b), (c) and (d) shall not apply to requirements, defaults or 
violations which would not have a material adverse effect on the business, 
operations or financial condition of Purchaser.

4.5 BROKERS' FEES.  No investment banker, broker, finder or other intermediary 
has been retained by or is authorized to act on behalf of Purchaser who might 
be entitled to any fee or commission from the Company upon consummation of 
the transactions contemplated by this Agreement.

4.6  SUITABILITY.  Purchaser is an "accredited investor" or is represented by 
a "purchaser representative" as defined in Rule 501 of Regulation D 
promulgated under the Securities Act.

4.7  INVESTMENT.  Purchaser is acquiring the number of Shares set forth 
opposite Purchaser's name on the Schedule of Purchasers for investment for 
Purchaser's own account and not with a view to, or for resale in connection 
with, any distribution of the Shares.  Purchaser understands that the Shares 
have not been registered under the Securities Act by reason of a specific 
exemption from the registration provisions of the Securities Act which 
depends upon, among other things, the BONA FIDE nature of Purchaser's 
investment intent as expressed herein.

4.8 RULE 144.  Purchaser acknowledges that, because they have not been 
registered under the Securities Act, the Shares constitute "restricted 
securities" as defined in Rule 144(a)(3) and must be held indefinitely unless 
subsequently registered under the Securities Act or an exemption from such 
registration is available.  Purchaser is aware of the provisions of Rule 144 
promulgated under the Securities Act which permit limited resale of 
securities purchased in a private placement subject to the satisfaction of 
certain conditions, including,

<PAGE>

among other things, the existence of a public market for the securities, the 
availability of certain current public information about the issuer, the 
resale occurring not less than one year after a party has purchased and paid 
for the security to be sold, the sale being through a "broker's transaction" 
or in transactions directly with a "market maker" (as provided by Rule 
144(f)) and the number of securities being sold during any three-month period 
not exceeding specified limitations (unless the securities satisfy the 
requirements of Rule 144(k)).

5. COVENANTS OF THE COMPANY.

5.1 INVESTIGATION.  Upon reasonable notice, prior to the Closing Date the 
Company shall afford to Purchasers or to any of Purchaser's officers, 
employees, accountants, counsel and other authorized representatives full and

acknowledged, the parties agree as follows:

1. ACQUISITION. At the Closing Date (as defined herein) for the acquisition 
of each of the buildings included in the Pending Projects, the Sellers who 
own that building (as indicated on Appendix I) (the "Participating Sellers") 
agree to convey, and the Purchaser agrees to acquire, such property subject 
to the terms and conditions of this Agreement. The Sellers' shall appoint one 
representative to act as their agent in connection with the acquisition and

2. ACQUISITION VALUE. The acquisition value for the conveyance of each of the

                                    RECITALS

      A. The Optionors are the owners of, or have the right to acquire, three
(3) tracts of real property located in Santa Clara County and Alameda County,
California, commonly known as King Ranch Business Park, Hellyer and Piercy, and
Fremont and Cushing, and described in attached Exhibit A, together with all

guaranties given by unaffiliated third parties owned by the Optionors and
pertaining to or used exclusively in connection with the Berg Land Holdings (the
"Personal Property"); (the Berg Land Holdings and Personal Property shall be
collectively referred to herein as the "Berg Land Holdings").

      B. In connection with the Acquisition Agreement dated as of May 14,

all are parties, the Operating Partnership has agreed to issue L.P. Units to

      C. The Operating Partnership is governed by the Operating Partnership

      D. The Optionee desires to have an option to acquire the Berg Land
Holdings and the Optionors desire to grant such an option to Optionee on the

and fully leased by issuing either additional L.P. Units to the Optionors based
upon the Acquisition Value (as defined below), or at the Optionors' option, they
may receive cash or a combination of cash and L.P. Units equal to the
Acquisition Value.

      E. This Agreement shall become effective (the "Option Effective Date").

                                    AGREEMENT

      NOW THEREFORE, in consideration of the mutual covenants and promises of
the parties, the parties hereto agree as follows:

1. OPTION. Optionor grants Optionee an exclusive option ("Option") to purchase
each of the acquired properties comprising the Berg Land Holdings. The Option
shall be "rolling" and shall apply to each acquired property. The fact that
Optionee does not exercise the Option with respect to a given acquired property
shall not impact Optionee's right to exercise the Option with respect to a
subsequent acquired property. The Optionors' shall appoint one representative to
act as their agent in connection with the acquisition and conveyance of each
acquired  property  (the  "Optionors'  Representative").  The  Optionors'
Representative is authorized to receive written notices from the Optionee on
behalf of all of the Optionors of such property. This Option does not create any
right to acquire any portion of the Berg Land Holdings prior to the development
of a completed building thereon, fully leased.

2. TERM OF OPTION. The term of the Option ("Term") shall commence on the Option
Effective Date and, unless Optionee has timely exercised the Option in
accordance with the provisions hereof, shall terminate on the sooner of (i) the
"Percentage Interest Date" (as defined below), or (ii) 11:59 p.m. on December
31, 2010. The Percentage Interest Date shall be the date on which the "Berg
Group" as defined in the Acquisition Agreement no longer owns or has the right
to acquire 65% of the Company's Common Stock, determined as though all L.P.
Units owned in the aggregate by the Berg Group were exchanged for shares of
Common Stock at the Exchange Factor.

<PAGE>

3. CONSIDERATION. As consideration for the Option, Optionee has paid to Optionor
the sum of Ten and No/100 Dollars ($10. 00) ("Option Consideration"), the
receipt and sufficiency of which are hereby acknowledged.

4. DEVELOPMENT OF BERG LAND HOLDINGS. Optionor intends to develop the Berg Land
Holdings and construct thereon various industrial buildings,  subject to
obtaining the necessary governmental permits and approvals. This development
will occur over several years and shall be accomplished in a manner that
Optionor determines, in its sole discretion, is prudent based upon market
conditions. This development will occur over several years and shall be
accomplished in a manner that Optionor determines, in its sole discretion, is
prudent based upon market conditions. The properties commonly known as Hellyer
and Piercy and Fremont and Cushing are not yet owned by Optionors, but are
subject to acquisition agreements wherein the Optionors have the right to
acquire such properties. If the Optionors decide not to exercise their rights to
acquire such properties, then such properties shall no longer be deemed to be
part of the Berg Land Holdings and shall no longer be subject to the terms of
this Option.

5. EXERCISE. The exercise of the Option with respect to a given acquired
property must occur within thirty (30) days of receipt of the "Completion
Notice" from Optionor's Representative to Optionee. The Completion Notice shall
be delivered by Optionor's Representative to Optionee with respect to each
acquired property in the Berg Land Holdings once the following has occurred (i)
the completion of the building and receipt of required occupancy permits; (ii)
the execution of written leases with respect to one hundred percent (100%) of
the rentable square footage in such building, and (iii) the Optionors' election
as to the form of consideration they intend to receive for the acquired
property. Optionee may exercise the Option at any time during such thirty
(30)-day period by written notice ("Notice") to Optionor, stating the date upon
which Optionee desires to close escrow (provided that escrow shall not close
later than the sixtieth (60th) day following receipt of the Completion Notice).

6. ACQUISITION VALUE. In the event that Optionee exercises the Option, the
Acquisition Value for the subject acquired property shall be equal to (i) the
full construction cost of all improvements on or servicing the acquired
property, plus (ii) 10% of the amount set forth in subsection (i), plus (iii)
the acquisition value of the parcel on which the improvements were constructed
as set forth in the schedule below and interest at LIBOR from January 1, 1998
until the close of escrow, plus (iv) property tax and assessment payments on
such property prorated from January 1, 1998, plus (v) interest at LIBOR on the
amounts set forth in subsections (i) and (iv) from the date paid by Optionor and
ending at the close of escrow, minus (v) the sum of the principal amount of all
debt encumbering the subject acquired property as of the closing. Optionee shall
assume all assessments that are a lien against the subject acquired property.
The acquisition value of each parcel of the Berg Land Holdings shall be as
follows:

7. PAYMENT OF ACQUISITION VALUE. The Acquisition Value shall be paid in cash or
L.P. Units, at the election of the Optionor's Representative. To the extent the
Optionor's Representative elects to receive L.P. Units, the number of L.P. Units
(N) paid to Optionor shall be determined as follows:

      (A-B)/C=N; where:

          A = Acquisition Value

          B = Any cash portion of the Acquisition Value paid to Optionor

          C = The average market value of the Common Stock over the 30
          trading-day period preceding the exercise of the Option.

8. AGREEMENT OF PURCHASE AND SALE. Within seven (7) days after exercise of the
Option by Optionee, Optionee and Optionors each shall execute an agreement of
purchase and sale for the purchase of the subject acquired property by Optionee
from Optionors. The Purchase Agreement shall be in the form of the agreement of
purchase and sale ("Form Purchase Agreement) attached hereto as Exhibit B;

escrow,  and (d) the legal description of the acquired property to be
transferred.

owners of, or have a valid and binding agreement to acquire, the Berg Land
Holdings, and have (or will have prior to the close of escrow under the Purchase
Agreement) insurable fee simple title to the acquired property clear of

Purchase Agreement. If this option is exercised by Optionee, Optionors will
convey title to the acquired property by California statutory grant deed.

10. ASSIGNMENT. Optionee shall have the right to assign the Option with the
prior consent of Optionors (whose consent shall be subject to their sole and
absolute discretion).

11. NO TRANSFER OF PARCEL. From and after the Option Effective Date, unless and
until this Agreement is terminated, Optionors shall not sell or convey or grant
an option to sell or convey all or any portion of the Berg Land Holdings if such

("Agreement") is entered into as of ____________________ (the "Effective Date")
by  and  between  _______________________________  (the  "Seller"),  and
____________________, a California limited partnership (the "Purchaser") with
reference to the following facts:

                                    RECITALS

      A. Seller is the owner of certain real property comprising approximately
acres of improved real property located at _____________________________,
_____________ County, California, commonly known as ________________________, as
more particularly described in attached Exhibit A, together with all rights,
privileges, easements, and appurtenances (collectively, the "Property"); and all
personal property, entitlements, licenses, permits, development rights, air
rights, authorizations, certificates, surveys, plans, specifications, reports,
studies, test results and all unexpired warranties and guaranties given by
unaffiliated third parties owned by Seller and pertaining to or used exclusively
in connection with the Property (the "Personal Property"); (the Property and
Personal Property shall be collectively referred to herein as the "Property").

      B. Purchaser desires to purchase the Property and Seller desires to sell
the Property on the terms and conditions in this Agreement.

                                    AGREEMENT

      For good and valuable consideration, the receipt and adequacy of which are
acknowledged, the parties agree as follows:

1. PURCHASE AND SALE. Seller agrees to sell and Purchaser agrees to purchase the
Property subject to the terms and conditions in this Agreement.

2. ACQUISITION  VALUE. The Acquisition Value for the Property shall be
________________ (the "Acquisition Value") and shall be payable as follows:

Purchaser and held in the Escrow in an interest bearing account.

   [SEE PARAGRAPH 7 OF BERG LAND HOLDINGS OPTION AGREEMENT ON HOW THE BALANCE

3. ESCROW. By this Agreement, Purchaser and Seller establish an escrow

escrow, but only to the extent that the standard conditions impose no additional
obligations or liabilities on the parties, and further subject to the terms and

5.   FEASIBILITY PERIOD.

(a) During the period commencing on the Effective Date and terminating ten (10)
days thereafter (the "Feasibility  Period"),  Purchaser may undertake at
Purchaser's expense a review and inspection of the Property, including, but not
limited to a review of the title to the Property, a review of the physical
condition of the Property, including, but not limited to, inspection and
examination of soils, environmental factors, hazardous substances, if any, and
archeological information relating to the Property; a review and investigation
of the effect of any zoning, maps, permits, reports, engineering data,
regulations, ordinances, and laws affecting the Property; a review, after such
examination and study it may deem appropriate, as to whether the Property can be
economically and timely operated in accordance with Purchaser's proposed plan
for the Property, including but not limited, to a marketing and finance
analysis; a review to determine whether Purchaser can obtain any and all final
governmental and private approvals as may be deemed necessary by Purchaser in
Purchaser's sole and absolute  discretion to permit  Purchaser's  future
development and operation of the Property; a review to determine whether or not
water, sewer or electrical and other utilities can be brought to the Property in
an economical and timely fashion in sufficient quality and quantity to permit
the development and operation in the manner,  currently contemplated by
Purchaser's current development and operation plan for the Property, as that
plan may be modified from time to time hereinafter; and such other tests,
investigations or analysis as Purchaser deems necessary in its sole and absolute
discretion and otherwise subject to the restrictions set forth below. Within
five (5) days following the Effective Date, Seller shall deliver to (or
otherwise make available for reasonable inspection by) Purchaser copies of all
architectural plans, surveys, specifications, contracts, licenses, reports,
environmental reports, seismic reports, studies, test results, tax bills,
expense information and other documents pertaining to the Property that are
owned by and in the possession of Seller (the "Operative Documents").

(b) If Purchaser disapproves of the results of the inspection and review for any
reason, which determination may be made by Purchaser in its sole and absolute
discretion, Purchaser may elect, prior to the expiration of the Feasibility
Period, to terminate this Agreement by giving Seller written notification
thereof, and the Deposit together with all interest earned thereon shall be
returned to Purchaser. If Purchaser fails to properly notify Seller of the
intent to terminate this Agreement, Purchaser shall be deemed to be satisfied

<PAGE>

with the results of the inspection and shall be deemed to have waived the right
to terminate this Agreement pursuant to this provision.

6. CONDITIONS TO PURCHASER'S PERFORMANCE. Purchaser's obligation to perform
under this Agreement is subject to the following conditions:

(a) Purchaser's approval of the Property as provided in Section 5;

and containing such endorsements as may be reasonably required by Purchaser; and

(e) There shall not have occurred after the Effective Date any material adverse
physical change in the Property from its condition as of the Effective Date.

The conditions (a) through (e) shall be for the benefit of, and may be waived
by, Purchaser. Upon the non-satisfaction of any of the foregoing conditions,
unless waived by Purchaser, the Agreement shall be terminated and any Deposit
then held by Escrow Agent together with all interest thereon shall be returned
to Purchaser.

7. CONDITIONS TO SELLER'S PERFORMANCE. Seller's obligation to perform under this
Agreement is subject to the following conditions:

(a) Purchaser's representations in this Agreement being correct in all material
respects as of the date of this Agreement and as of the Closing Date; and

(b) Purchaser's performance of all of its obligations under this Agreement.

The conditions (a) and (b) shall be for the benefit of, and may be waived by,
Seller. Upon the non-satisfaction of any of the foregoing conditions, unless
waived by Seller, the Agreement shall be terminated and any Deposit then held by
Escrow Agent together with all interest thereon and any sums previously released
to Seller shall be returned to Purchaser.

8.    ACCESS.

(a) Access to the Property prior to the Closing Date shall be given to Purchaser
during normal business hours upon at least one (1) business day's prior notice
to Seller.

(b) Purchaser and Purchaser's contractors and consultants shall have the right,
from the Effective Date until the Closing Date, to enter onto the Property, at
their own cost and risk, for any purposes, including but not limited to,
inspecting the Property, taking samples of the soil, and conducting an
environmental audit (including an investigation of past and current uses of the
Property). In addition, Purchaser shall have the right to contact any federal,
state, or local governmental authority or agency to investigate any matters
relating to the Property. Purchaser's contractors and consultants shall be duly
licensed and insured. As a condition of such entry, Purchaser shall provide
evidence reasonably satisfactory to Seller of the existence of general liability
insurance prior to any such entry, inspection, test or study. Seller agrees to

<PAGE>

cooperate reasonably with Purchaser in the inspection of the Property and agrees
to make available to Purchaser all information in Seller's possession or control
pertaining to the condition of the Property, including engineering and
environmental reports, studies, tests, monitoring results, and related
documentation.

(c) Purchaser shall indemnify and defend Seller against and hold Seller harmless
from all losses, costs, damages, liabilities, and expenses, arising out of any
personal injury or physical damage to the Property in connection with
Purchaser's inspection of or presence, prior to the Closing Date, on the
Property. Furthermore, Purchaser shall indemnify, defend and hold Seller
harmless from and against any mechanic's lien claims that may arise in
connection with Purchaser's inspection of or presence, prior to the Closing
Date, on the Property.

9.    TITLE.

(a) Immediately following the execution of this Agreement by both parties,
Purchaser shall cause Escrow Agent to issue to Purchaser (with a copy to Seller)
a preliminary report for a CLTA Owner's Policy for the Property, setting forth
all liens, encumbrances, easements, restrictions, conditions, and other record
matters affecting Seller's title to the Property (the "Preliminary Report"),
together with copies of all documents relating to title exceptions referred to
in the Preliminary Report. Purchaser shall have the right, prior to the
expiration of the Feasibility Period, to obtain an ALTA survey, at its own
expense, sufficient for the issuance of an ALTA Owner's Extended Coverage Policy
of Title Insurance.

(b) Purchaser shall approve or disapprove each exception shown on the
Preliminary Report and in any ALTA supplement issued in connection therewith
(each an "Exception") by the date which is the later to occur of (i) the
expiration of the Feasibility Period or (ii) five (5) days following the receipt
of each of the Preliminary Report, the underlying exceptions, and any ALTA
supplement to the Preliminary Report, as the case may be. Any Exception not so
timely disapproved shall be deemed an "Approved Exception."

(c) If any Exception is disapproved (each a "Disapproved Exception") Seller
shall have the option either to notify Purchaser (i) that Seller will attempt to
remove or cure such Disapproved Exception prior to the Closing Date or (ii) that
Seller will take no action whatsoever; provided, however, Seller's failure to
notify Purchaser of Seller's election of any of its foregoing options within
five (5) business days after Seller's receipt of Purchaser's notice of a
Disapproved Exception shall be deemed Seller's election of option (ii). In the
event that Seller elects or is deemed to have selected option (ii) then
Purchaser shall, within five (5) days after Purchaser's receipt or deemed
receipt of Seller's election, either elect to waive such Disapproved Exception
and proceed to the Close of Escrow without offset or deduction or to terminate
this Agreement, in which latter event Purchaser shall pay all reasonable charges
to the Escrow Agent in connection with this transaction and all the funds and
documents deposited with Escrow Agent shall be promptly refunded or returned, as
the case may be by Escrow Agent to the depositing party. Purchaser's failure to
so timely notify Seller of Purchaser's election will be deemed Purchaser's
election to waive the Disapproved Exception. In the event Seller elects option
(i) Seller shall, prior to the Closing Date, use its good faith reasonable
efforts to cause each Disapproved Exception to be discharged, satisfied,
released, or terminated, as the case may be, of record, and in a form that is
reasonably satisfactory to Purchaser and Escrow Agent, all at Seller's sole cost

<PAGE>

and expense. Seller shall have no liability if despite the use of its good faith
reasonable efforts, it cannot cure the Disapproved Exception and Purchaser shall
again have the option to either terminate this Agreement or waive such
Disapproved Exception and proceed to closing without offset or deduction.

(d) Notwithstanding anything contained in this Agreement to the contrary, it is
agreed that any monetary encumbrance affecting title to the Property, other than
a lien for current real property taxes and assessments not then delinquent,
shall be discharged by Seller on the Closing Date and need not be formally
disapproved by Purchaser. Seller hereby authorizes Escrow Agent to disburse from
the cash portion of the Acquisition Value and proceeds otherwise disbursable to
Seller upon the Close of Escrow the sum sufficient to discharge any monetary
encumbrances that may be discharged only by the payment of money.

10.   CLOSE OF ESCROW.

(A) CONVEYANCE OF TITLE. At the Close of Escrow, good and marketable title to
the Property shall be conveyed by Seller to Purchaser by the Deed (as defined

assume all assessments that are a lien against the Property);

Purchaser in accordance with this Agreement;

(iii) Seller's affidavit as contemplated by Revenue and Taxation Code Section

reasonably require to close this transaction of purchase and sale in accordance
with the terms hereof.

Close of Escrow shall occur on that date which is no later than the sixtieth
(60th) day following receipt of the Completion Notice with respect to the
acquired property (the "Expected Closing Date"), or as soon thereafter as the
Escrow is in condition for. Close of Escrow; provided, however, that if the
Close of Escrow does not occur by the Expected Closing Date and the Expected
Closing Date is not extended by written agreement by the parties, a party hereto
not then in default under this Agreement may notify the other party and Escrow
Agent, in writing that, unless the Close of Escrow occurs within five (5)
business days following said notice, the Escrow and this Agreement shall be
deemed terminated without further notice or instructions and, in which event,
the party which is not in position to close shall be deemed to be in material
breach of this Agreement and the party that has fully complied may exercise its
remedies in accordance with the terms hereof.

(E) CLOSE OF ESCROW. On the Closing Date and provided that Escrow Agent is
irrevocably committed to issue a CLTA Owner's Policy of title insurance showing

(the "Title Policy"), Escrow Agent shall date all undated documents as of the

current installment of any bond or assessment that constitutes a lien on the
Property, rents, security deposits, and license fees, if any, including any
additional property taxes or installments of any bond or assessment lien that
may be assessed after the Close of Escrow, but that relate to a period prior to
the Close of Escrow, regardless of when notice of those taxes, dues or
assessments are received or who receives the notice shall be prorated as of the
Close of Escrow.

(IV) BALANCE OUTSIDE OF ESCROW. Any item to be prorated in accordance with the
terms of this Agreement which is not determined or determinable on the Closing
Date shall be adjusted by the parties by appropriate cash payment outside of the
Escrow within five (5) business days after the amount due is determined.

<PAGE>

Property prior to the Close of Escrow in an amount not exceeding Ten Thousand
Dollars ($10,000.00), Purchaser and Seller shall consummate this Agreement,
provided that Seller shall assign to Purchaser Seller's rights under any
insurance policy covering the damage or destruction and shall indemnify and
guarantee Purchaser with respect to any costs incurred by Purchaser in repairing
and restoring the Property after the Close of Escrow that are not paid by the
insurance up to the amount of Ten Thousand Dollars ($10,000.00) or may, at
Seller's election, grant Purchaser a credit in said amount against the
Acquisition Value.

(b) In the event of damage or destruction of the Property or any portion of the
Property prior to the Close of Escrow in an amount in excess of Ten Thousand
Dollars ($10,000.00), Purchaser may elect within ten (10) days following such
event of damage or destruction, either to terminate this Agreement upon written
notice to Seller and Escrow Agent or to consummate this Agreement, in which
event Seller shall assign to Purchaser Seller's rights under any insurance
policy covering the damage or destruction, but without the indemnity and
guarantee provided in subsection (a) above. Purchaser's failure to affirmatively
elect whether to terminate or consummate this Agreement within said ten (10) day
period shall be deemed Purchaser's election to consummate this Agreement. If
Purchaser elects to terminate this Agreement pursuant to this provision, Escrow
Agent and/or Seller, as the case may be, shall, within five (5) days following
receipt of Purchaser's notice, return the Deposit, to Purchaser.  Upon
termination, neither party shall have any further obligations under this
Agreement except as otherwise provided in this Agreement.

13.   CONDEMNATION.

is the subject of a threatened or pending condemnation or eminent domain
proceeding that has not been consummated prior to the Close of Escrow resulting

Agreement, provided that Seller shall assign to Purchaser Seller's rights to all
awards for the condemnation or taking and shall indemnify and guarantee
Purchaser with respect to any costs incurred by Purchaser in repairing and
restoring the Property that are not paid by the awards up to the amount of Ten
Thousand Dollars ($10,000.00) or may, at Seller's election, grant Purchaser a
credit in such amount against the Acquisition Value.

(b) If any portion of the Property is taken by condemnation or eminent domain or
is the subject of a threatened or pending condemnation or eminent domain
proceeding that has not been consummated prior to the Close of Escrow resulting
in a decrease in the value of the Property in an amount in excess of Ten
Thousand Dollars ($10,000.00), Purchaser may elect within ten (10) days
following such event, either to terminate this Agreement upon written notice to
Seller and Escrow Agent or to consummate this Agreement, in which event Seller
shall assign to Purchaser Seller's rights to all awards for the condemnation or
taking, but without the indemnity and guarantee provided in subSection (a)
above. Purchaser's failure to affirmatively elect whether to terminate or
consummate this Agreement within said ten (10) day period shall be deemed
Purchaser's election to consummate this Agreement. If Purchaser elects to
terminate this Agreement pursuant to this provision, Escrow Agent and/or Seller,
as the case may be, shall, within five (5) days following receipt of Purchaser's
notice, return the Deposit to Purchaser. Upon termination, neither party shall

The continued accuracy in all respects of Seller's representations shall be a
condition precedent to Purchaser's obligation to close. All representations
contained in this Agreement shall be deemed remade as of the Closing Date and
shall survive the Closing Date. If, after the Effective Date hereof, but prior
to the Closing Date, Seller becomes aware that any of the representations set

contemplated, in which case Purchaser shall be deemed to have waived all rights

notice. Notwithstanding the foregoing, nothing in this paragraph shall limit

                                 STANDARD FORM LEASE
- --------------------------------------------------------------------------------

PARTIES: This Lease, executed in duplicate at Cupertino, California, on May 19,
1998, by and between Berg & Berg Enterprises, Inc., a California Corporation,
and Mission West Properties, a California corporation, hereinafter called
respectively Lessor and Lessee, without regard to number or gender.


USE: WITNESSETH: That Lessor hereby leases to Lessee, and Lessee hires from
Lessor, for the purpose of conducting therein office, research and development,
light manufacturing, and warehouse activities, and any other legal activity; and
for no other purpose without obtaining the prior written consent of Lessor.

PREMISES: The real property with appurtenances as shown on Exhibit A (the
"Premises") situated in the City of Cupertino, County of Santa Clara, State of
California, and more particularly described as follows:

     Lessee's portion of the Premises is 3,200 square feet of an approximately
     7,500 square foot building, including all improvements thereto, as shown on
     Exhibit A.1 including the right to use its pro-rata share of the parking
     spaces located at the Premises.  The address for the leased portion of the
     Premises is 10050 Bandley Drive, Cupertino,  California.  Lessee's pro-rata
     share of the building is approximately 42.67%.

TERM: The term shall be for thirty-six  (36) months unless extended pursuant to
Section 35 of this Lease (the "Lease Term"), commencing on April 1, 1998 and
ending thirty-six (36) months thereafter.

RENT: Base rent shall be payable in monthly installments as follows: 

<TABLE>
<CAPTION>

                                   Base rent      Estimated CAC*      Total
                                   ---------      --------------      -----
     <S>                           <C>               <C>             <C>
     Months 1 through 36           $5,600            $1,120*         $6,720

</TABLE>

* CAC charges to be adjusted per Common Area Charges Section below.

Base rent and CAC as scheduled above shall be payable in advance on or before
the first day of each calendar month during the Lease Term.  The term "Rent," as
used herein, shall be deemed to be and to mean the base monthly rent and all
other sums required to be paid by Lessee pursuant to the terms of this Lease. 
Rent shall be paid in lawful money of the United States of America, without
offset or deduction, and shall be paid to Lessor at such place or places as may
be designated from time to time by Lessor.  Rent for any period less than a
calendar month shall be a pro rata portion of the monthly installment.  Upon
execution of this Lease, Lessee shall deposit with Lessor the first month's
rent.

SECURITY DEPOSIT: Lessee shall deposit with Lessor the sum of Six Thousand Seven
Hundred Twenty Dollars ($6,720) (the "Security Deposit").  The Security Deposit
shall be held by Lessor as security for the faithful performance by Lessee of
all of the terms, covenants, and conditions of this Lease applicable to Lessee. 
If Lessee commits a default as provided for herein, including but not limited to
a default with respect to the provisions contained herein relating to the
condition of the Premises, Lessor may (but shall not be required to) use, apply
or retain all or any part of the Security Deposit for the payment of any amount
which Lessor may spend by reason of default by Lessee.  If any portion of the
Security Deposit is so used or applied, Lessee shall, within ten days after
written demand therefor, deposit cash with Lessor in an amount sufficient to
restore the Security Deposit to its original amount.  Lessee's failure to do so
shall be a default by Lessee.  Any attempt by Lessee to transfer or encumber its
interest in the Security Deposit shall be null and void.  Upon execution of this
Lease, Lessee shall deposit with Lessor the Security Deposit.   Notwithstanding
the above, Lessor agrees to waive the requirement for Lessee to make a security
deposit provided Lessee's shareholder's equity exceeds $7.5 million.  If at any
time during this Lease, Lessee's shareholder's equity is less than $7.5 million,
Lessee shall deposit with Lessor the Security Deposit referenced above within
ten days after the issuance of Lessee's financial statements indicating the
reduction in shareholder's equity below $7.5 million.  If Lessee fails to make
the Security Deposit as required, Lessee shall be deemed to be in default per
Section 14.1 (a) of this Lease.

COMMON AREA CHARGES: Lessee shall pay to Lessor, as additional Rent, an amount
equal to Lessee's pro-rate share of the total common area charges of the
Premises as defined below (the common area charges for the Premises is referred
to herein as ("CAC")).  Lessee shall pay to Lessor as Rent, on or before the
first day of each calendar month during the Lease Term, subject to adjustment
and reconciliation as provided hereinbelow, the sum of One Thousand One Hundred
Twenty Dollars ($1,120), said sum representing Lessee's estimated monthly
payment of Lessee's percentage share of CAC.  It is understood and agreed that 

<PAGE>

Lessee's obligation under this paragraph shall be prorated to reflect the
Commencement Date and the end of the Lease Term.  Upon execution of this Lease,
Lessee shall deposit with Lessor the first month's estimated CAC.

Lessee's estimated monthly payment of CAC payable by Lessee during the calendar
year in which the Lease commences is set forth above.  At or prior to the
commencement of each succeeding calendar year term (or as soon as practical
thereafter), Lessor shall provide Lessee with Lessee's estimated monthly payment
for CAC which Lessee shall pay to Lessor as Rent.  Within 120 days of the end of
the calendar year and the end of the Lease Term, Lessor shall provide Lessee a
statement of actual CAC incurred including capital reserves for the preceding
year or other applicable period in the case of a termination year.  If such
statement shows that Lessee has paid less than its actual percentage, then
Lessee shall on demand pay to Lessor the amount of such deficiency.   If such
statement shows that Lessee has paid more than its actual percentage, then
Lessor shall, at its option, promptly refund such excess to Lessee or credit the
amount thereof to the Rent next becoming due from Lessee.  Lessor reserves the
right to revise any estimate of CAC if the actual or projected CAC show an
increase or decrease in excess of 10% from an earlier estimate for the same
period.  In such event, Lessor shall provide a revised estimate to Lessee,
together with an explanation of the reasons therefor, and Lessee shall revise
its monthly payments accordingly.  Lessor's and Lessee's obligation with respect
to adjustments at the end of the Lease Term or earlier expiration of this Lease
shall survive the Lease Term or earlier expiration.

As used in this Lease, CAC shall include but is not limited to: (i) items as
specified in Sections 5(b), 6, 12, 16 and 31; (ii) all costs and expenses
including but not limited to supplies, materials, equipment and tools used or
required in connection with the operation and maintenance of the Premises; (iii)
licenses, permits and inspection fees;  (iv) all other costs incurred by Lessor
in maintaining and operating the Premises; (v) all reserves for capital
replacements and government regulations imposed on the Premises not related to
Lessee's use and occupancy of the Premises; and (vi) an amount equal to five
percent (5%) of the aggregate of all CAC, as compensation for Lessor's
accounting and processing services.  Lessee shall have the right to review the
basis and computation analysis used to derive the CAC applicable to this Lease
annually.

LATE CHARGES: Lessee hereby acknowledges that a late payment made by Lessee to
Lessor of Rent and other sums due hereunder will cause Lessor to incur costs not
contemplated by this Lease, the exact amount of which will be extremely
difficult to ascertain.  Such costs include, but are not limited to, processing
and accounting charges, and late charges, which may be imposed on Lessor
according to the terms of any mortgage or trust deed covering the Premises. 
Accordingly, if any installment of Rent or any other sum due from Lessee is not
received by Lessor or Lessor's designee within ten (10) days after such amount
is due, Lessee shall pay to Lessor a late charge equal to five (5%) percent of
such overdue amount.  The parties hereby agree that such late charge represents
a fair and reasonable estimate of the costs Lessor will incur by reason of late
payments made by Lessee.  Acceptance of such late charges by Lessor shall in no
event constitute a waiver of Lessee's default with respect to such overdue
amount, nor shall it prevent Lessor from exercising any of the other rights and
remedies granted hereunder.

QUIET ENJOYMENT: Lessor covenants and agrees with Lessee that upon Lessee paying
Rent and performing its covenants and conditions under this Lease, Lessee shall
and may peaceably and quietly have, hold and enjoy the Premises for the Lease
Term, subject, however, to the rights reserved by Lessor hereunder.

OFFICE/OVERHEAD SHARING:  It is understood and acknowledged that the Premises
described herein shall be utilized for the business operations of both Lessor
and Lessee.  Lessee shall pay for or reimbursement Lessor for its prorata share,
to be determined by Lessor on an equitable basis, of all building and
operational expenses related to the use of the office, the equipment in the
office, office supplies, personnel costs, management costs, and any other costs
necessary for the operation of a professional management organization at the
Premises.  In addition, Lessee and Lessor shall each be responsible for the
exclusive costs of their own organization.  The primary purpose of this
arrangement is to utilize the existing resources of Lessor and its staff to
benefit Lessee at a reasonable cost to Lessee.  Notwithstanding the above,
Lessee's obligation under this Lease, including base rent, CAC, and
office/overhead sharing shall not exceed Fifteen Thousand Dollars ($15,400) per
month during the first thirty-six months of the Lease Term.    

IT IS FURTHER MUTUALLY AGREED BETWEEN THE PARTIES AS FOLLOWS:
1.   POSSESSION: Possession shall be deemed tendered and the term shall commence
effective April 1, 1998.

PAGE 2
<PAGE>

2.1 ACCEPTANCE OF PREMISES AND COVENANTS TO SURRENDER: Lessee accepts the
Premises in an "AS IS" condition and "AS IS" state of repair, subject to
Lessor's representation that the Premises are in good order and repair, and
comply with all requirements for occupancy as of the Commencement Date.  Lessee
agrees on the last day of the Lease Term, or on the sooner termination of this
Lease, to surrender the Premises to Lessor in Good Condition and Repair.  Good
Condition and Repair ("Good Condition and Repair") shall not mean original
condition, but shall mean that the Premises are in a commercially acceptable
condition suitable for occupancy by a reasonable lessee.  The interior walls of
all office and warehouse areas, the floors of all office and warehouse areas,
all suspended ceilings and any carpeting are to be cleaned and in Good Condition
and Repair. Lessee, on or before the end of the Lease Term or sooner termination
of this Lease, shall remove all its personal property and trade fixtures from
the Premises, and all such property not so removed shall be deemed to be
abandoned by Lessee.  Lessee shall reimburse Lessor for all disposition costs
incurred by Lessor relative to Lessee's abandoned property.  If the Premises are
not surrendered at the end of the Lease Term or earlier termination of this
Lease, Lessee shall indemnify Lessor against loss or liability resulting from
any delay caused by Lessee in surrendering the Premises including, without
limitation, any claims made by any succeeding Lessee founded on such delay.  

3. USES PROHIBITED: Lessee shall not commit, or suffer to be committed, any
waste upon the Premises, or any nuisance, or other act or thing which may
disturb the quiet enjoyment of any other tenant in or around the buildings in
which the subject Premises are located or allow any sale by auction upon the
Premises, or allow the Premises to be used for any improper, immoral, unlawful
or objectionable purpose, or place any loads upon the floor, walls, or ceiling
which may endanger the structure, or use any machinery or apparatus which will
in any manner vibrate or shake the Premises or the building of which it is a
part, or place any harmful liquids in the drainage system of the building.  No
waste materials or refuse shall be dumped upon or permitted to remain upon any
part of the Premises outside of the building proper.  No materials, supplies,
equipment, finished products or semi-finished products, raw materials or
articles of any nature shall be stored upon or permitted to remain on any
portion of the Premises outside of the building structure, unless approved by
the local, state federal or other applicable governing authority.  Lessor
consents to Lessee's use of materials which are incidental to the normal,
day-to-day operations of any office user, such as copier fluids, cleaning
materials, etc., but this does not relieve Lessee of any of its obligations not
to contaminate the Premises and related real property or violate any Hazardous
Materials Laws.

4. ALTERATIONS AND ADDITIONS: Lessee shall not make, or suffer to be made, any
alteration or addition to said Premises, or any part thereof, without the
express, advance written consent of Lessor; any addition or alteration to said
Premises, except movable furniture and trade fixtures, shall become at once a
part of the realty and belong to Lessor at the end of the Lease Term or earlier
termination of this Lease.  Alterations and additions which are not deemed as
trade fixtures shall include HVAC systems, lighting systems, electrical systems,
partitioning, carpeting, or any other installation which has become an integral
part of the Premises.  Lessee agrees that it will not proceed to make such
alterations or additions until all required government permits have been
obtained and after having obtained consent from Lessor to do so, until five (5)
days from the receipt of such consent, so that Lessor may post appropriate
notices to avoid any liability to contractors or material suppliers for payment
for Lessee's improvements.  Lessee shall at all times permit such notices to be
posted and to remain posted until the completion of work.  At the end of the
Lease Term or earlier termination of this Lease, Lessee shall remove and shall
be required to remove its special tenant improvements, all related equipment,
and any additions or alterations installed by Lessee at or during the Lease Term
and Lessee shall return the Premises to the condition that existed before the
installation of the tenant improvements.  Notwithstanding the above, Lessor
agrees to allow any reasonable alterations and improvements and will use its
best efforts to notify Lessee at the time of approval if such improvements or
alterations are to be removed at the end of the Lease Term  or earlier
termination of this Lease.

5. MAINTENANCE OF PREMISES: 
     (a) Lessee shall at its sole cost and expense keep, repair, and maintain
     the interior of the Premises, including, but not limited to, all lighting
     systems, temperature control systems, and plumbing systems in Good
     Condition and Repair, including any required replacements.  Lessee shall
     maintain all wall surfaces and floor coverings in Good Condition and
     Repair, free of holes, gouges, or defacements and provide interior and
     exterior window washing as needed.

     Lessee's use of the Premises) the following, which shall be included in the
     monthly CAC:

          quarterly maintenance of all air conditioning and heating equipment at
          the Premises including HVAC repairs or replacements which are either
          excluded from such service contract or any existing equipment
          warranties.
          3. The landscaping by a landscape contractor to water, maintain, trim
          and replace, when necessary, any shrubbery and landscaping at the
          Premises.
          4. The roof membrane by a service contract with a licensed reputable
          roofing contractor which contract shall provide for a minimum of
          semi-annual maintenance, cleaning of storm gutters, drains, removing

          application of a finish coat every five years to the building at the
          Premises.
          5. Exterior pest control.
          6. Fire monitoring services.

     (c) Lessee hereby waives any and all rights to make repairs at the expense
     of Lessor as provided in Section 1942 of the Civil Code of the State of
     California, and all rights provided for by Section 1941 of said Civil Code.

     (d) Lessor shall be responsible for the repair of any structural defects in
     the Premises including the roof structure (not membrane), exterior walls
     and foundation during the Lease Term.

6. INSURANCE:
     A) HAZARD INSURANCE: Lessee shall not use, or permit said Premises, or any
     part thereof, to be used, for any purpose other than that for which the
     Premises are hereby leased; and no use shall be made or permitted to be
     made of the Premises, nor acts done, which may cause a cancellation of any
     insurance policy covering the Premises, or any part thereof, nor shall
     Lessee sell or permit to be kept, used or sold, in or about said Premises,
     any article which may be prohibited by a fire and extended coverage
     insurance policy.  Lessee shall comply with any and all requirements,
     pertaining to said Premises, of any insurance organization or company,
     necessary for the maintenance of reasonable fire and extended coverage
     insurance, covering the Premises.  Lessor shall, at Lessee's sole cost and
     expense, purchase and keep in force fire and extended coverage insurance,
     covering loss or damage to the  Premises in an amount equal to the full
     replacement cost of the Premises, as determined by Lessor, with proceeds
     payable to Lessor.  In the event of a loss per the insurance provisions of
     this paragraph, Lessee shall be responsible for deductibles up to a maximum
     of $5,000 per occurrence.  Lessee acknowledges that the insurance
     referenced in this paragraph does not include coverage for Lessee's
     personal property.  

     B) LOSS OF RENTS INSURANCE: Lessor shall, at Lessee's sole cost and
     expense, purchase and maintain in full force and effect, a policy of rental
     loss insurance, in an amount equal to the amount of Rent payable by Lessee
     commencing on the date of loss for the next ensuing one (1) year, as
     reasonably determined by Lessor with proceeds payable to Lessor ("Loss of
     Rents Insurance"). 

     C) LIABILITY AND PROPERTY DAMAGE INSURANCE: Lessee, as a material part of
     the consideration to be rendered to Lessor, hereby waives all claims
     against Lessor and Lessor's Agents for damages to goods, wares and
     merchandise, and all other personal property in, upon, or about the
     Premises, and for injuries to persons in, upon, or about the Premises, from
     any cause arising at any time, and Lessee will hold Lessor and Lessor's
     Agents exempt and harmless from any damage or injury to any person, or to
     the goods, wares, and merchandise and all other personal property of any
     person, arising from the use or occupancy of the Premises by Lessee, or
     from the failure of Lessee to keep the Premises in Good Condition and
     Repair, as herein provided.  Lessee shall, at Lessee's sole cost and
     expense, purchase and keep in force a standard policy of commercial general
     liability insurance and property damage policy covering the Premises and
     all related areas insuring the 

PAGE 4
<PAGE>

     Lessee  having a combined single limit for both bodily injury, death and
     property damage in an amount not less than five million dollars
     ($5,000,000.00) and Lessee's insurance shall be primary.  The limits of
     said insurance shall not, however, limit the liability of Lessee hereunder.
     Lessee shall, at its sole cost and expense, comply with all of the
     insurance requirements of all local, municipal, state and federal
     authorities now in force, or which may hereafter be in force, pertaining to
     Lessee's use and occupancy of the said Premises. 

     D) PERSONAL PROPERTY INSURANCE: Lessee shall obtain, at Lessee's sole cost
     and expense, a policy of fire and extended coverage insurance including
     coverage for direct physical loss special form, and a sprinkler leakage
     endorsement insuring the personal property of Lessee.  The proceeds from
     any personal property damage policy shall be payable to Lessee. 

All insurance policies required in 6 C) and 6 D) above shall: (i) provide for a
certificate of insurance evidencing the insurance required herein, being
deposited with Lessor ten (10) days prior to the Commencement Date, and upon
each renewal, such certificates shall be provided 30 days prior to the
expiration date of such coverage, (ii) be in a form reasonably satisfactory to
Lessor and shall provide the coverage required by Lessee in this Lease, (iii) be
carried with companies with a Best Rating of A+ minimum, (iv) specifically
provide that such policies shall not be subject to cancellation, reduction of
coverage, or other change except after 30 days prior written notice to Lessor,
(v) name Lessor, Lessor's lender, and any other party with an insurable interest
in the Premises as additional insureds by endorsement to policy, and (vi) shall
be primary.

Lessee agrees to pay to Lessor, as additional Rent, on demand, the full cost of
the insurance polices referenced in 6 A) and 6 B)  above as evidenced by
insurance billings to Lessor which shall be included in the CAC.  If Lessee does
not occupy the entire Premises, the insurance premiums shall be allocated to the
portion of the Premises occupied by Lessee on a pro-rata square footage or other
equitable basis, as determined by Lessor.  It is agreed that Lessee's obligation
under this paragraph shall be prorated to the reflect the Commencement Date and
the end of the Lease Term.

Lessor and Lessee hereby waive any rights each may have against the other
related to any loss or damage caused to Lessor or Lessee as the case may be, or
to the Premises or its contents, and which may arise from any risk generally
covered by fire and extended coverage insurance.  The parties shall provide that
their respective insurance policies insuring the property or the personal
property include a waiver of any right of subrogation which said insurance
company may have against Lessor or Lessee, as the case may be.

7. ABANDONMENT: Lessee shall not vacate or abandon the Premises at any time
during the Lease Term; and if Lessee shall abandon, vacate or surrender said
Premises, or be dispossessed by process of law, or otherwise, any personal
property belonging to Lessee and left on the Premises shall be deemed to be
abandoned, at the option of Lessor.  Notwithstanding the above, the Premises
shall not be considered vacated or abandoned if Lessee maintains the Premises in
Good Condition and Repair, provides security and is not in default.

8. FREE FROM LIENS: Lessee shall keep the subject Premises and the property in
which the subject Premises are situated, free from any and all liens including
but not limited to liens arising out of any work performed, materials furnished,
or obligations incurred by Lessee.  However, the Lessor shall allow Lessee to
contest a lien claim, so long as the claim is discharged prior to any
foreclosure proceeding being initiated against the property and provided Lessee
provides Lessor a bond if the lien exceeds $5,000.

9. COMPLIANCE WITH GOVERNMENTAL REGULATIONS: Lessee shall, at its sole cost and
expense, comply with all of the requirements of all local, municipal, state and
federal authorities now in force, or which may hereafter be in force, pertaining
to  the Premises, and shall faithfully observe in the use and occupancy of the
Premises all local and municipal ordinances and state and federal statutes now
in force or which may hereafter be in force. 

10. INTENTIONALLY OMITTED.

11. ADVERTISEMENTS AND SIGNS: Lessee shall not place or permit to be placed, in,
upon or about the Premises any unusual or extraordinary signs, or any signs not
approved by the city, local, state, federal or other applicable governing
authority. Lessee 

PAGE 5
<PAGE>

shall not place, or permit to be placed upon the Premises, any signs,
advertisements or notices without the written consent of the Lessor, and such
consent shall not be unreasonably withheld.  A sign so placed on the Premises
shall be so placed upon the understanding and agreement that Lessee will remove
same at the end of the Lease Term or earlier termination of this Lease and
repair any damage or injury to the Premises caused thereby, and if not so
removed by Lessee, then Lessor may have the same removed at Lessee's expense.

12. UTILITIES: Lessee shall pay for all water, gas, heat, light, power,
telephone and other utilities supplied to the Premises which shall be included
in Lessee's monthly estimated CAC.  Any charges for sewer usage, PG&E and
telephone site service or related fees shall be the obligation of Lessee and
paid for by Lessee and shall be included in Lessee's monthly estimated CAC.  If
any such services are not separately metered to Lessee, Lessee shall pay a
reasonable proportion of all charges which are jointly metered, the
determination to be made by Lessor acting reasonably and on any equitable basis.
Lessor and Lessee agree that Lessor shall not be liable to Lessee for any
disruption in any of the utility services to the Premises.

13. ATTORNEY'S FEES: In case suit should be brought for the possession of the
Premises, for the recovery of any sum due hereunder, because of the breach of
any other covenant herein, or to enforce, protect, or establish any term,
conditions, or covenant of this Lease or the right of either party hereunder,
the losing party shall pay to the Prevailing Party reasonable attorney's fees
which shall be deemed to have accrued on the commencement of such action and
shall be enforceable whether or not such action is prosecuted to judgment.  The
term "Prevailing Party" shall mean the party that received substantially the
relief requested, whether by settlement, dismissal, summary judgment, judgment,
or otherwise.

14.1 DEFAULT: The occurrence of any of the following shall constitute a default
and breach of this Lease by Lessee: a) Any failure by Lessee to pay Rent or to
make any other payment required to be made by Lessee hereunder when due if not
cured within ten (10) days after written notice thereof by Lessor to Lessee; b)
The abandonment or vacation of the Premises by Lessee except as provided in
Section 7; c) A failure by Lessee to observe and perform any other provision of
this Lease to be observed or performed by Lessee, where such failure continues
for thirty days after written notice thereof by Lessor to Lessee; provided,
however, that if the nature of such default is such that the same cannot be
reasonably cured within such thirty (30) day period, Lessee shall not be deemed
to be in default if Lessee shall, within such period, commence such cure and
thereafter diligently prosecute the same to completion; d) The making by Lessee
of any general assignment for the benefit of creditors; the filing by or against
Lessee of a petition to have Lessee adjudged a bankrupt or of a petition for
reorganization or arrangement under any law relating to bankruptcy; e) the
appointment of a trustee or receiver to take possession of substantially all of
Lessee's assets or Lessee's interest in this Lease, or the attachment, execution
or other judicial seizure of substantially all of Lessee's assets located at the
Premises or of Lessee's interest in this Lease.

14.2 SURRENDER OF LEASE: In the event of any such default by Lessee, then in
addition to any other remedies available to Lessor at law or in equity, Lessor
shall have the immediate option to terminate this Lease before the end of the
Lease Term and all rights of Lessee hereunder, by giving written notice of such
intention to terminate.  In the event that Lessor terminates this Lease due to a
default of Lessee, then Lessor may recover from Lessee: a) the worth at the time
of award of any unpaid Rent which had been earned at the time of such
termination; plus b) the worth at the time of award of unpaid Rent which would
have been earned after termination until the time of award exceeding the amount
of such rental loss that the Lessee proves could have been reasonably avoided;
plus c) the worth at the time of award of the amount by which the unpaid Rent
for the balance of the Lease Term after the time of award exceeds the amount of
such rental loss that the Lessee proves could have been reasonably avoided; plus
d) any other amount necessary to compensate Lessor for all the detriment
proximately caused by Lessee's failure to perform his obligations under this
Lease or which in the ordinary course of things would be likely to result
therefrom; and e) at Lessor's election, such other amounts in addition to or in
lieu of the foregoing as may be permitted from time to time by applicable
California law.  As used in (a) and (b) above, the "worth at the time of award"
is computed by allowing interest at the rate of Wells Fargo's prime rate plus
two percent (2%) per annum.  As used in (c) above, the "worth at the time of
award" is computed by discounting such amount at the discount rate of the
Federal Reserve Bank of San Francisco at the time of award plus one percent
(1%).

<PAGE>

14.3 RIGHT OF ENTRY AND REMOVAL: In the event of any such default by Lessee,
Lessor shall also have the right, with or without terminating this Lease, to
re-enter the Premises and remove all persons and property from the Premises;
such property may be removed and stored in a public warehouse or elsewhere at
the cost of and for the account of Lessee.

14.4 ABANDONMENT: In the event of the vacation or abandonment, except as
provided in Section 7, of the Premises by Lessee or in the event that Lessor
shall elect to re-enter as provided in paragraph 14.3 above or shall take
possession of the Premises pursuant to legal proceeding or pursuant to any
notice provided by law, and Lessor does not elect to terminate this Lease as
provided in Section 14.2 above, then Lessor may from time to time, without
terminating this Lease, either recover all Rent as it becomes due or relet the
Premises or any part thereof for such term or terms and at such rental rates and
upon such other terms and conditions as Lessor, in its sole discretion, may deem
advisable with the right to make alterations and repairs to the Premises.  In
the event that Lessor elects to relet the Premises, then Rent received by Lessor
from such reletting shall be applied; first, to the payment of any indebtedness
other than Rent due hereunder from Lessee to Lessor; second, to the payment of
any cost of such reletting; third, to the payment of the cost of any alterations
and repairs to the Premises; fourth, to the payment of Rent due and unpaid
hereunder; and the residue, if any, shall be held by Lessor and applied to the
payment of future Rent as the same may become due and payable hereunder.  Should
that portion of such Rent received from such reletting during any month, which
is applied by the payment of Rent hereunder according to the application
procedure outlined above, be less than the Rent payable during that month by
Lessee hereunder, then Lessee shall pay such deficiency to Lessor immediately
upon demand therefor by Lessor.  Such deficiency shall be calculated and paid
monthly.  Lessee shall also pay to Lessor, as soon as ascertained, any costs and
expenses incurred by Lessor in such reletting or in making such alterations and
repairs not covered by the rentals received from such reletting.

14.5 NO IMPLIED TERMINATION: No re-entry or taking possession of the Premises by
Lessor pursuant to Section 14.3 or Section 14.4 of this Lease shall be construed
as an election to terminate this Lease unless a written notice of such intention
is given to Lessee or unless the termination thereof is decreed by a court of
competent jurisdiction.  Notwithstanding any reletting without termination by
Lessor because of any default by Lessee, Lessor may at any time after such
reletting elect to terminate this Lease for any such default. 

15. SURRENDER OF LEASE: The voluntary or other surrender of this Lease by
Lessee, or a mutual cancellation thereof, shall not work a merger, and shall, at
the option of Lessor, terminate all or any existing subleases or sub tenancies,
or may, at the option of Lessor, operate as an assignment to him of any or all
such subleases or sub tenancies.

16. TAXES: Lessee shall pay and discharge punctually and when the same shall
become due and payable without penalty, all real estate taxes, personal property
taxes, taxes based on vehicles utilizing parking areas in the Premises, taxes
computed or based on rental income (other than federal, state and municipal net
income taxes), environmental surcharges, privilege taxes, excise taxes, business
and occupation taxes, school fees or surcharges, gross receipts taxes, sales
and/or use taxes, employee taxes, occupational license taxes, water and sewer
taxes, assessments (including, but not limited to, assessments for public
improvements or benefit), assessments for local improvement and maintenance
districts, and all other governmental impositions and charges of every kind and
nature whatsoever, regardless of whether now customary or within the
contemplation of the parties hereto and regardless of whether resulting from
increased rate and/or valuation, or whether extraordinary or ordinary, general
or special, unforeseen or foreseen, or similar or dissimilar to any of the
foregoing (all of the foregoing being hereinafter collectively called "Tax" or
"Taxes") which, at any time during the Lease Term, shall be applicable or
against the Premises, or shall become due and payable and a lien or charge upon
the Premises under or by virtue of any present or future laws, statutes,
ordinances, regulations, or other requirements of any governmental authority
whatsoever.  The term "Environmental Surcharge" shall include any and all
expenses, taxes, charges or penalties imposed by the Federal Department of
Energy, Federal Environmental Protection Agency, the Federal Clean Air Act, or
any regulations promulgated thereunder, or any other local, state or federal
governmental agency or entity now or hereafter vested with the power to impose
taxes, assessments or other types of surcharges as a means of controlling or
abating environmental pollution or the use of energy in regard to the use,
operation or occupancy of the Premises.  The term "Tax" shall include, without
limitation, all taxes, assessments, levies, fees, impositions or charges levied,
imposed, assessed, measured, or based in any manner whatsoever (i) in whole or
in part on the Rent payable by Lessee under this Lease, (ii) upon or with
respect to the use, possession, occupancy, leasing, operation or management of
the Premises, (iii) upon this transaction or any document to which Lessee is a
party creating or transferring an 

PAGE 7
<PAGE>

interest or an estate in the Premises, (iv) upon Lessee's business operations
conducted at the Premises, (v) upon, measured by or reasonably attributable to
the cost or value of Lessee's equipment, furniture, fixtures and other personal
property located on the Premises or the cost or value of any leasehold
improvements made in or to the Premises by or for Lessee, regardless of whether
title to such improvements shall be in Lessor or Lessee, or (vi) in lieu of or
equivalent to any Tax set forth in this Section 16.  In the event any such Taxes
are payable by Lessor and it shall not be lawful for Lessee to reimburse Lessor
for such Taxes, then the Rent payable thereunder shall be increased to net
Lessor the same net rent after imposition of any such Tax upon Lessor as would
have been payable to Lessor prior to the imposition of any such Tax.  It is the
intention of the parties that Lessor shall be free from all such Taxes and all
other governmental impositions and  charges of every kind and nature whatsoever.
However, nothing contained in this Section 16 shall require Lessee to pay any
Federal or State income, franchise, estate, inheritance, succession, transfer or
excess profits tax imposed upon Lessor.   If any general or special assessment
is levied and assessed against the Premises, Lessor agrees to use its best
reasonable efforts to cause the assessment to become a lien on the Premises
securing repayment of a bond sold to finance the improvements to which the
assessment relates which is payable in installments of principal and interest
over the maximum term allowed by law.  It is understood and agreed that Lessee's
obligation under this paragraph will be prorated to reflect the Commencement
Date and the end of the Lease Term.  It is further understood that if Taxes
cover the Premises and Lessee does not occupy the entire Premises, the Taxes
will be allocated to the portion of the Premises occupied by Lessee based on a
pro-rata square footage or other equitable basis, as determined by Lessor. 
Taxes billed by Lessor to Lessee shall be included in the monthly CAC.  

Subject to any limitations or restrictions imposed by any deeds of trust or
mortgages now or hereafter covering or affecting the Premises, Lessee shall have
the right to contest or review the amount or validity of any Tax by appropriate
legal proceedings but which is not to be deemed or construed in any way as
relieving, modifying or extending Lessee's covenant to pay such Tax at the time
and in the manner as provided in this Section 16.  However, as a condition of
Lessee's right to contest, if such contested Tax is not paid before such contest
and if the legal proceedings shall not operate to prevent or stay the collection
of the Tax so contested, Lessee shall, before instituting any such proceeding,
protect the Premises and the interest of Lessor and of the beneficiary of a deed
of trust or the mortgagee of a mortgage affecting the Premises against any lien
upon the Premises by a surety bond, issued by an insurance company acceptable to
Lessor and in an amount equal to one and one-half (1 1/2) times the amount
contested or, at Lessor's option, the amount of the contested Tax and the
interest and penalties in connection therewith.  Any contest as to the validity
or amount of any Tax, whether before or after payment, shall be made by Lessee
in Lessee's own name, or if required by law, in the name of Lessor or both
Lessor and Lessee.  Lessee shall defend, indemnify  and hold harmless Lessor
from and against any and all costs or expenses, including attorneys' fees, in
connection with any such proceedings brought by Lessee, whether in its own name
or not. Lessee shall be entitled to retain any refund of any such contested Tax
and penalties or interest thereon which have been paid by Lessee.  Nothing
contained herein shall be construed as affecting or limiting Lessor's right to
contest any Tax at Lessor's expense.

17. NOTICES: Unless otherwise provided for in this Lease, any and all written
notices or other communication (the "Communication") to be given in connection
with this Lease shall be given in writing and shall be given by personal

or refused or if given by recognized overnight courier, on the first business
day following deposit with such overnight courier and if given by facsimile
transmission, on the day on which it was transmitted provided such day is a
business day, failing which, on the next business day thereafter.   

18. ENTRY BY LESSOR: Lessee shall permit Lessor and its agents to enter into and
upon said Premises at all reasonable times using the minimum amount of
interference and inconvenience to Lessee and Lessee's business, subject to any
security regulations of Lessee, for the purpose of inspecting the same or for
the purpose of maintaining the building in which said Premises are situated, or
for the purpose of making repairs, alterations or additions to any other portion
of said building, including the erection and maintenance of such scaffolding,
canopies, fences and props as may be required, without any rebate of Rent and
without any liability to Lessee for any loss of occupation or quiet enjoyment of
the Premises; and shall permit Lessor and his agents, at any time within ninety
(90) days prior to the end of the Lease Term, to place upon said Premises any
usual or ordinary "For Sale" or "For Lease" signs and exhibit the Premises to
prospective tenants at reasonable hours.

19. DESTRUCTION OF PREMISES: In the event of a partial destruction of the said
Premises during the Lease Term from any cause which is covered by Lessor's
property insurance, Lessor shall forthwith repair the same, provided such
repairs can be made within ninety (90) days after receipt of building permit
under the laws and regulations of State, Federal, County, or Municipal
authorities, but such partial destruction shall in no way annul or void this
Lease, except that Lessee shall be entitled to a proportionate reduction of Rent
while such repairs are being made to the extent of payments received by Lessor
under its Loss of Rents Insurance coverage.  With respect to any partial
destruction which Lessor is obligated to repair or may elect to repair under the
terms of this paragraph, the provision of Section 1932, Subdivision 2, and of
Section 1933, Subdivision 4, of the Civil Code of the State of California are
waived by Lessee.  In the event that the building in which the subject Premises
may be situated is destroyed to an extent greater than thirty-three and
one-third percent (33 1/3%) of the replacement cost thereof, Lessor may, at its
sole option, elect to terminate this Lease, whether the subject Premises is
insured or not.  A total destruction of the building in which the subject
Premises are situated shall terminate this Lease.  Notwithstanding the above,
Lessor is only obligated to repair or rebuild to the extent of available
insurance proceeds including any deductible amount.  Should Lessor determine
that insufficient or no insurance proceeds are available for repair or
reconstruction of Premises, Lessor, at its sole option, may terminate the Lease.
Lessee shall have the option of continuing this Lease by agreeing to pay all
repair costs to the subject Premises.

20. ASSIGNMENT AND SUBLETTING: Lessee shall not assign this Lease, or any
interest therein, and shall not sublet the said Premises or any part thereof, or
any right or privilege appurtenant thereto, or cause any other person or entity
(a bona fide subsidiary or affiliate of Lessee excepted) to occupy or use the
Premises, or any portion thereof, without the advance written consent of Lessor.
Any such assignment or subletting without such consent shall be void, and shall,
at the option of the Lessor, terminate this Lease.  This Lease shall not, or
shall any interest therein, be assignable, as to the interest of Lessee, by
operation of law, without the written consent of Lessor.  Notwithstanding
Lessor's obligation to provide reasonable approval, Lessor reserves the right to
withhold its consent for any proposed sublessee or assignee of Lessee if the
proposed sublessee or assignee is a user or generator of Hazardous Materials. 
If Lessee desires to assign its rights under this Lease or to sublet, all or a
portion of the subject Premises to a party other than a bona fide subsidiary or
affiliate of Lessee, Lessee shall first notify Lessor of the proposed terms and
conditions of such assignment or subletting.  Lessor shall have the right of
first refusal to enter into a direct Lessor-lessee relationship with such party
under such proposed terms and conditions, in which event Lessee shall be
relieved of its obligations hereunder to the extent of the Lessor-lessee
relationship entered into between Lessor and such third party.  Notwithstanding
the foregoing, Lessee may assign this Lease to a successor in interest, whether
by merger or acquisition, provided there is no substantial reduction in the net
worth of the resulting entity and the resulting entity is not a user or
generator of Hazardous Materials.  Whether or not Lessor's consent to a sublease
or assignment is required, in the event of any sublease or assignment, Lessee
shall be and shall remain primarily liable for the performance of all
conditions, covenants, and obligations of Lessee hereunder and, in the event of
a default by an assignee or sublessee, Lessor may proceed directly against the
original Lessee hereunder and/or any other predecessor of such assignee or
sublessee without the necessity of exhausting remedies against said assignee or
sublessee.

21. CONDEMNATION: If any part of the Premises shall be taken for any public or
quasi-public use, under any statute or by right of eminent domain or private
purchase in lieu thereof, and a part thereof remains which is susceptible of
occupation hereunder, this Lease shall as to the part so taken, terminate as of
the date title vests in the condemnor or purchaser, and the Rent payable
hereunder shall be adjusted so that the Lessee shall be required to pay for the
remainder of the Lease Term only that portion of Rent as the value of the part
remaining.  The rental adjustment resulting will be computed at the same Rental
rate for the remaining part not taken; however, Lessor shall have the option to
terminate this Lease as of the date when title to the part so taken vests in the
condemnor or purchaser.  If all of the Premises, or such part thereof be taken
so that there does not remain a portion susceptible for occupation hereunder,
this Lease shall thereupon terminate.  If a part or all of the Premises be
taken, all compensation awarded upon such taking shall be payable to the Lessor.
Lessee may file a separate claim and be entitled to any award granted to Lessee.

22. EFFECTS OF CONVEYANCE: The term "Lessor" as used in this Lease, means only
the owner for the time being of the land and building constituting the Premises,
so that, in the event of any sale of said land or building, or in the event of a
Lease of said building, Lessor shall be and hereby is entirely freed and
relieved of all covenants and obligations of Lessor hereunder, and it shall be
deemed and construed, without further agreement between the parties and the
purchaser of any such sale, or the Lessor of the building, that the purchaser or
lessor of the building has assumed and agreed to carry out any and all covenants
and obligations of the Lessor hereunder.  If any security is given by Lessee to
secure the faithful performance of all or any of the covenants of this Lease on
the part of Lessee, Lessor may transfer and deliver the security, as such, to
the purchaser at any such sale of the building, and thereupon the Lessor shall
be discharged from any further liability.

23. SUBORDINATION: This Lease, in the event Lessor notifies Lessee in writing,
shall be subordinate to any ground lease, deed of trust, or other hypothecation
for security now or hereafter placed upon the real property at which the
Premises are a part and to any and all advances made on the security thereof and
to renewals, modifications, replacements and extensions thereof. Lessee agrees
to promptly execute any documents which may be required to effectuate such
subordination. Notwithstanding such subordination, if Lessee is not in default
and so long as Lessee shall pay the Rent and observe and perform all of the
provisions and covenants required under this Lease, Lessee's right to quiet
possession of the Premises shall not be disturbed or effected by any
subordination.

24. WAIVER: The waiver by Lessor of any breach of any term, covenant or
condition, herein contained shall not be construed to be a waiver of such term,
covenant or condition or any subsequent breach of the same or any other term,
covenant or condition therein contained.  The subsequent acceptance of Rent
hereunder by Lessor shall not be deemed to be a waiver of Lessee's breach of any
term, covenant, or condition of the Lease.

25. HOLDING OVER: Any holding over after the end of the Lease Term requires
Lessor's written approval prior to the end of the Lease Term, which,
notwithstanding any other provisions of this Lease, Lessor may withhold.  Such
holding over shall be construed to be a tenancy at sufferance from month to
month.  Lessee shall pay to Lessor monthly base rent equal to one and one-half
(1.5) times the monthly base rent installment due in the last month of the Lease
Term and all other additional rent and all other terms and conditions of the
Lease shall apply, so far as applicable.  Holding over by Lessee without written
approval of Lessor shall subject Lessee to the liabilities and obligations
provided for in this Lease and by law, including, but not limited to those in
Section 2 of this Lease.  Lessee shall indemnify and hold Lessor harmless
against any loss or liability resulting from any delay caused by Lessee in
surrendering the Premises, including without limitation, any claims made or
penalties incurred by any succeeding lessee or by Lessor.  No holding over shall
be deemed or construed to exercise any option to extend or renew this Lease in
lieu of full and timely exercise of any such option as required hereunder.

26. LESSOR'S LIABILITY: If Lessee should recover a money judgment against Lessor
arising in connection with this Lease, the judgment shall be satisfied only out
of the Lessor's interest in the Premises and neither Lessor or any of its
partners shall be liable personally for any deficiency.

27. ESTOPPEL CERTIFICATES: Lessee shall at any time during the Lease Term, upon
not less than ten (10) days prior written notice from Lessor, execute and
deliver to Lessor a statement in writing certifying that, this Lease is
unmodified and in full force and effect (or, if modified, stating the nature of
such modification) and the dates to which the Rent and other charges have been
paid 

PAGE 10
<PAGE>

in advance, if any, and acknowledging that there are not, to Lessee's knowledge,
any uncured defaults on the part of Lessor hereunder or specifying such defaults
if they are claimed.  Any such statement may be conclusively relied upon by any
prospective purchaser or encumbrancer of the Premises.  Lessee's failure to
deliver such a statement within such time shall be conclusive upon the Lessee
that (a) this Lease is in full force and effect, without modification except as
may be represented by Lessor; (b) there are no uncured defaults in Lessor's
performance.

28. TIME: Time is of the essence of the Lease.

29. CAPTIONS: The headings on titles to the paragraphs of this Lease are not a
part of this Lease and shall have no effect upon the construction or
interpretation of any part thereof.  This instrument contains all of the
agreements and conditions made between the parties hereto and may not be
modified orally or in any other manner than by an agreement in writing signed by
all of the parties hereto or their respective successors in interest.

30. PARTY NAMES: Landlord and Tenant may be used in various places in this Lease
as a substitute for Lessor and Lessee respectively.

31. EARTHQUAKE INSURANCE: As a condition of Lessor agreeing to waive the
requirement for earthquake insurance, Lessee agrees that it will pay, as
additional Rent, which shall be included in the monthly CAC, an amount not to
exceed One Thousand Two Hundred Eighty Dollars ($1,280) per year for earthquake
insurance if Lessor desires to obtain some form of earthquake insurance in the
future, if and when available, on terms acceptable to Lessor as determined in
the sole and absolute discretion of Lessor.

32. HABITUAL DEFAULT: Notwithstanding anything to the contrary contained in
Section 14 herein, Lessor and Lessee agree that if Lessee shall have defaulted
in the payment of Rent for three or more times during any twelve month period
during the Lease Term, then such conduct shall, at the option of the Lessor,
represent a separate event of default which cannot be cured by Lessee.  Lessee
acknowledges that the purpose of this provision is to prevent repetitive
defaults by the Lessee under the Lease, which constitute a hardship to the
Lessor and deprive the Lessor of the timely performance by the Lessee hereunder.

35. OPTION TO EXTEND
A. OPTION: Lessor hereby grants to Lessee one (1) option to extend the Lease
Term, with the extended term to be for a period of three (3) years, on the
following terms and conditions:

     (i) Lessee shall give Lessor written notice of its exercise of its option
     to extend no earlier than twenty-four (24) calendar months, nor later than
     six (6) calendar months before the Lease Term would end but for said
     exercise.  Time is of the essence.

     (ii) Lessee may not extend the Lease Term pursuant to any option granted by
     this Section 35 if Lessee is in default as of the date of the exercise of
     its option.  If Lessee has committed a default by Lessee as defined in
     Section 14 or 32 that has not been cured or waived by Lessor in writing by
     the date that any extended term is to commence, then Lessor may elect not
     to allow the Lease Term to be extended, notwithstanding any notice given by
     Lessee of an exercise of this option to extend.

     (iii) All terms and conditions of this Lease shall apply during the
     extended term, except that the base rent and rental increases for each
     extended term shall be determined as provided in Section 35 (B) below

     (iv) Lessee must provide Lessor written notice of its exercise of its
     option as provided hereunder at least nine (9) months before the Lease Term
     would end but for said exercise for purposes of negotiating rental terms. 
     Lessee may withdraw its notice of exercise of an extension option for any
     reason prior to six (6) months before the Lease Term would end but for said
     exercise.  Lessor shall provide Lessee with Lessor's proposed base monthly
     rent for the option period within twenty (20) days of Lessee's written
     request.  However, once Lessee delivers a notice of exercise of an option
     to extend the Lease Term it may not be withdrawn unless notice in writing
     is provided to Lessor at least six (6) months before the Lease Term would
     end but for said exercise and, subject to the provisions of this Section
     35, such notice shall operate to extend the Lease Term.  Upon any extension
     of the Lease Term pursuant to this Section 35, the term "Lease Term" as
     used in this Lease shall thereafter include the then extended term. 

     (v) The option rights of Mission West Properties  granted under this
     Section 35 are granted for Mission West Properties' personal benefit and
     may not be assigned or transferred by Mission West Properties or exercised
     if Mission West Properties is not occupying the Premises at the time of
     exercise.

B. EXTENDED TERM RENT - OPTION PERIOD: The monthly Rent for the Premises during
the extended term shall equal the fair market monthly Rent for the Premises as
of the commencement date of the extended term, but in no case, less than the
Rent during the last month of the prior Lease term.  Promptly upon Lessee's
exercise of the option to extend, Lessee and Lessor shall meet and attempt to
agree on the fair market monthly Rent for the Premises as of the commencement
date of the extended term.  In the event the parties fail to agree upon the
amount of the monthly Rent for the extended term prior to commencement thereof,
the monthly Rent for the extended term shall be determined by appraisal in the
manner hereafter set forth; provided, however, that in no event shall the
monthly Rent for the extended term be less than in the immediate preceding
period.  Annual base rent increases during the extended term shall be four
percent (4%) per year.  In the event it becomes necessary under this paragraph 

PAGE 13
<PAGE>

to determine the fair market monthly Rent of the Premises by appraisal, Lessor
and Lessee each shall appoint a real estate appraiser who shall be a member of
the American Institute of Real Estate Appraiser ("AIREA") and such appraisers
shall each determine the fair market monthly Rent for the Premises taking into
account the value of the Premises and the amenities provided by the outside
areas, the common areas, and the Building, and prevailing comparable Rentals in
the area.  Such appraisers shall, within twenty (20) business days after their
appointment, complete their appraisals and submit their appraisal reports to
Lessor and Lessee.  If the fair market monthly Rent of the Premises established
in the two (2) appraisals varies by five percent (5%) or less of the higher
Rent, the average of the two shall be controlling.  If said fair market monthly
Rent varies by more than five percent (5%) of the higher Rental, said
appraisers, within ten (10) days after submission of the last appraisal, shall
appoint a third appraiser who shall be a member of the AIREA and who shall also
be experienced in the appraisal of Rent values and adjustment practices for
commercial properties in the vicinity of the Premises.  Such third appraiser
shall, within twenty (20) business days after his appointment, determine by
appraisal the fair market monthly Rent of the Premises taking into account the
same factors referred to above, and submit his appraisal report to Lessor and
Lessee.  The fair market monthly Rent determined by the third appraiser for the
Premises shall be controlling, unless it is less than that set forth in the
lower appraisal previously obtained, in which case the value set forth in said
lower appraisal shall be controlling, or unless it is greater than that set
forth in the higher appraisal previously obtained in which case the Rent set for
in said higher appraisal shall be controlling.  If either Lessor or Lessee fails
to appoint an  appraiser, or if an appraiser appointed by either of them fails,
after his appointment to submit his appraisal within the required period in
accordance with the foregoing, the appraisal submitted by the appraiser properly
appointed and timely submitting his appraisal shall be controlling.  If the two
appraisers appointed by Lessor and Lessee are unable to agree upon a third
appraiser within the required period in accordance with the foregoing,
application shall be made within twenty (20) days thereafter by either Lessor or
Lessee to AIREA, which shall appoint a member of said institute willing to serve
as appraiser.  The cost of all appraisals under this subparagraph shall be borne
equally be Lessor and Lessee.

36. APPROVALS: Whenever in this Lease the Lessor's or Lessee's consent is
required, such consent shall not be unreasonably or arbitrarily withheld or
delayed.  In the event that the Lessor or Lessee does not respond to a request
for any consents which may be required of it in this Lease within ten business
days of the request of such consent in writing by the Lessee or Lessor, such
consent shall be deemed to have been given by the Lessor or Lessee.

37. AUTHORITY: Each party executing this Lease represents and warrants that he
or she is duly authorized to execute and deliver the Lease.  If executed on
behalf of a corporation, that the Lease is executed in accordance with the
by-laws of said corporation (or a partnership that the Lease is executed in
accordance with the partnership agreement of such partnership), that no other
party's approval or consent to such execution and delivery is required, and that
the Lease is binding upon said individual, corporation (or partnership) as the
case may be in accordance with its terms.  

38. INDEMNIFICATION OF LESSOR: Except to the extent caused by the sole
negligence or willful misconduct of Lessor or Lessor's Agents, Lessee shall
defend, indemnify and hold Lessor harmless from and against any and all
obligations, losses, costs, expenses, claims, demands, attorney's fees,
investigation costs or liabilities on account of, or arising out of the use,
condition or occupancy of the Premises or any act or omission to act of Lessee
or Lessee's Agents or any occurrence in, upon, about or at the Premises,
including, without limitation, any of the foregoing provisions arising out of
the use, generation, manufacture, installation, release, discharge, storage, or
disposal of Hazardous Materials by Lessee or Lessee's Agents.  It is understood
that Lessee is and shall be in control and possession of the Premises and that
Lessor shall in no event be responsible or liable for any injury or damage or
injury to any person whatsoever, happening on, in, about, or in connection with
the Premises, or for any injury or damage to the Premises or any part thereof. 
This Lease is entered into on the express condition that Lessor shall not be
liable for, or suffer loss by reason of injury to person or property, from
whatever cause, which in any way may be connected with the use, condition or
occupancy of the Premises or personal property located herein. The provisions of
this Lease permitting Lessor to enter and inspect the Premises are for the
purpose of enabling Lessor to become informed as to whether Lessee is complying
with the terms of this Lease and Lessor shall be under no duty to enter, inspect
or to perform any of Lessee's covenants set forth in this Lease.  Lessee shall
further indemnify, defend and hold harmless Lessor from and against any and all
claims arising from any breach or default in the performance of any obligation
to Lessee's part to be performed under the terms of this Lease.  The provisions
of Section 38 shall survive the Lease Term or earlier termination of this Lease
with respect to any damage, injury or death occurring during the Lease Term.

                                GRANT PURSUANT TO
                             1997 STOCK OPTION PLAN
     
MICHAEL J. ANDERSON, OPTIONEE:
     
Mission West Properties, a California corporation (the "Company"), hereby grants
to Optionee,  an option  ("Option") to purchase a total of two hundred  thousand
(200,000)  shares of Common Stock  ("Shares")  of the Company,  at the price set
forth  herein,  and in  all  respects  subject  to the  terms,  definitions  and
provisions  of  the  Company's  1997  Stock  Option  Plan  ("Plan"),   which  is
incorporated herein by this reference.
     
THE DETAILS OF YOUR OPTION ARE AS FOLLOWS:
     
1.    NATURE OF THE OPTION
The Option is intended to be an  incentive  stock  option  within the meaning of
Section 422 of the Internal  Revenue Code of 1986, as amended (the  "Code").  To
the extent  that the  Option,  or any  portion  thereof,  does not qualify as an
incentive  stock option under the Code because the  aggregate  fair market value
(determined  at the grant  date) of the  Shares  for which the Option or portion
thereof first becomes  exercisable  hereunder  will, when added to the aggregate
fair market value  (determined as of the  respective  date or dates of grant) of
the  Shares  or other  securities  for which  the  Option  or one or more  other
incentive stock options granted to the Optionee prior to the grant date (whether
under the Plan or any other  option  plan of the  Corporation  or any  Parent or
Subsidiary) first becomes  exercisable during the calendar year, exceed $100,000
in the aggregate,  the Option or portion  thereof shall  constitute an incentive
stock  option  under the Plan in such  calendar  year only to the extent of such
$100,000 limitation.  To the extent that the fair market value of the Shares for
which the Option first  becomes  exercisable  in any calendar  year exceeds such
$100,000  limitation,  the Option may nevertheless be exercised for those excess
Shares in such calendar year as a  "Nonstatutory  Stock  Option",  as defined in
Section 2.o of the Plan.
     
2.    OPTION PRICE
The Option Price is four dollars and fifty cents ($4.50) for each Share.
     
3     VESTING AND EXERCISE OF OPTION
The Option shall vest and become  exercisable during its term in accordance with
the provisions of Section 9 of the Plan as follows:
      a.   VESTING AND RIGHT TO EXERCISE
           i. The  Option  shall  vest as  follows,  subject  to the  Optionee's

           Subject to the  provisions  of  subparagraphs  ii and iii below,  the
           Optionee can exercise any portion of the Option until the  expiration
           of the Option term. Notwithstanding the foregoing, but subject to the
           provisions of subparagraph ii below, at the election of the Optionee,
           the Option can be exercised in whole or in part at any time as to the
           Shares which have not vested,  provided that the Optionee shall, as a
           condition of such exercise,  execute and deliver the Restricted Stock
           Purchase  Agreement in the form attached  hereto  ("Restricted  Stock
           Purchase Agreement"),  pursuant to which the Company shall be granted
           a  Repurchase  Option  as to all  Unvested  Shares  (as such  term is
           defined in the Restricted Stock Purchase Agreement). ii. In the event
           of  the  Optionee's   death,   disability  or  other  termination  of
           employment,  the  exercisability  of the Option  shall be governed by
           Sections  9.d,  e and f of the  Plan.  iii.  The  Option  may  not be
           exercised for fractional shares or for less than ten (10) Shares
     
      b.   METHOD OF EXERCISE
      In order to exercise any portion of this Option, the Optionee shall notify
      the Company in writing of the election to exercise the Option,  the number
      of shares in respect of which the Option is being  exercised  by executing
      and delivering the Notice of Exercise of Stock Option in the form attached
      hereto,  and shall execute and deliver to the Chief  Financial  Officer of
      the Company the  Restricted  Stock Purchase  Agreement,  together with the
      Stock  Assignments,  Escrow  Agreement and, if applicable,  the Consent of
      Spouse,  Promissory  Note,  and  Security  Agreement,  forms of which  are
      attached as exhibits  to the  Restricted  Stock  Purchase  Agreement.  The
      Restricted Stock Purchase Agreement must be accompanied by payment in full
      of the  aggregate  purchase  price  for the  Shares to be  purchased.  The
      certificate or  certificates  representing  Shares as to which this Option
      has been  exercised  shall be registered  in the name of the Optionee.  b.
      RESTRICTIONS  ON EXERCISE This Option may not be exercised if the issuance
      of the Shares upon such exercise or the method of payment of consideration
      for such shares would constitute a violation of any applicable  Federal or
      state securities law or other law or regulation.  Furthermore,  the method
      and manner of  payment  of the  Option  Price will be subject to the rules
      under Part 207 of Title 12 of the Code of Federal Regulations ("Regulation
      G") as promulgated by the Federal Reserve Board if such rules apply to the
      Company at the date of  exercise.  As a condition  to the exercise of this
      Option, the Company may require the Optionee to make any representation or
      warranty  to the  Company at the time of exercise of this Option as in the
      opinion of legal counsel for the Company may be required by any applicable
      law or regulation,  including the execution and delivery of an appropriate
      representation  statement.  Accordingly,  the stock  certificates  for the
      Shares  issued upon exercise of this Option may bear  appropriate  legends
      restricting transfer.
     
4.    NON-TRANSFERABILITY OF OPTION
This Option may be exercised  during the  lifetime of the  Optionee  only by the
Optionee and,  subject to the provisions of Sections 9.f and 10 of the Plan, may
not be  transferred  in any manner  other than by will or by the laws of descent
and distribution.  The terms of this Option shall be binding upon the executors,
administrators, heirs and successors of the Optionee.
     
5.    METHOD OF PAYMENT
Payment of the exercise price shall be by any of the following, or a combination
thereof, at the election of the Optionee:
      a.   cash;
      b.   certified or bank cashier's check;
      c. full  recourse  promissory  note  secured by the  Shares or  equivalent
      collateral;  or d. in the  event  there  exists  a public  market  for the
      Company's  Common  Stock on the date of  exercise,  by  delivery of a sell
      order to a broker for the shares being  purchased  and an agreement to pay
      (or have the broker remit  payment  for) the purchase  price of the shares
      being  purchased  on or before  the  settlement  date for the sale of such
      shares to the broker;  or e. in the event there exists a public market for
      the Company's Common Stock on the date of exercise, by surrender of shares
      of the Company's Common Stock,  provided that if such shares were acquired
      upon exercise of an incentive  stock option,  the Optionee must have first
      satisfied the holding period  requirements  under Section 422(a)(1) of the
      Code. In this case payment shall be made as follows:
           i. In addition to the execution and delivery of the Restricted  Stock
           Purchase  Agreement,  Optionee  shall deliver to the Secretary of the
           Company a written  notice  which  shall set forth the  portion of the
           purchase price the Optionee wishes to pay with Common Stock,  and the
           number  of shares  of such  Common  Stock  the  Optionee  intends  to
           surrender  pursuant to the  exercise of this  Option,  which shall be
           determined  by dividing  the  aforementioned  portion of the purchase
           price by the average of the last  reported  bid and asked  prices per
           share of Common Stock of the Company,  as reported in THE WALL STREET
           JOURNAL,  for the day on which  the  notice  of  exercise  is sent or
           delivered;  ii.  Fractional  shares  shall  be  disregarded  and  the
           Optionee  shall  pay  in  cash  an  amount  equal  to  such  fraction
           multiplied by the price determined under  subparagraph i above;  iii.
           The written  notice shall be  accompanied  by a duly  endorsed  blank
           stock  power  with  respect  to the number of Shares set forth in the
           notice,  and the  certificate(s)  representing  said Shares  shall be
           delivered to the Company at its  principal  offices  within three (3)
           working  days  from the  date of the  notice  of  exercise;  iv.  The
           Optionee  hereby  authorizes and directs the Secretary of the Company
           to transfer so many of the Shares represented by such  certificate(s)
           as are  necessary to pay the purchase  price in  accordance  with the
           provisions  herein;  v. If any such  transfer of Shares  requires the
           consent of the California  Commissioner  of  Corporations  or of some
           other agency  under the  securities  laws of any other  state,  or an
           opinion of counsel for the Company or Optionee that such transfer may
           be effected under  applicable  Federal and state securities laws, the
           time periods  specified  herein shall be extended for such periods as
           the necessary  request for consent to transfer is pending before said
           Commissioner  or other  agency,  or  until  counsel  renders  such an
           opinion, as the case may be. All parties agree to cooperate in making
           such request for transfer,  or in obtaining  such opinion of counsel,
           and no transfer shall be effected  without such consent or opinion if
           required by law; and vi.  Notwithstanding any other provision herein,
           the Optionee  shall only be permitted to pay the purchase  price with
           Shares of the Company's  Common Stock owned by him as of the exercise
           date in the manner and within the time periods  allowed  under 17 CFR
           ss.240.16b-3  promulgated under the Securities  Exchange Act of 1934,
           as  amended   ("Exchange  Act"),  as  such  regulation  is  presently
           constituted,  as it is  amended  from  time  to  time,  and  as it is
           interpreted   now  or  hereafter  by  the   Securities  and  Exchange
           Commission.
     
6. ADJUSTMENTS UPON CHANGES IN  CAPITALIZATION  OR MERGER.  The number of Shares
covered by this Option shall be adjusted in  accordance  with the  provisions of
Section  11 of the  Plan  in the  event  of  changes  in the  capitalization  or
organization  of the Company,  or if the Company is a party to a merger or other
corporate reorganization.
     
7.    TERM OF OPTION
This Option may not be exercised  more than six (6) years from the date of grant
of this Option,  as set forth below,  and may be exercised during such term only
in accordance with the Plan and the terms of this Option.
     
8.    REPURCHASE RIGHTS
The Optionee  hereby  agrees that any Shares  acquired upon the exercise of this
Option shall be subject to the rights of the Company to  repurchase  such Shares
to the extent  such Shares  have not yet vested and to certain  restrictions  on
transfer specified in the Restricted Stock Purchase Agreement.
     
9.    NOT EMPLOYMENT CONTRACT
Nothing in this  Agreement  or in the Plan shall  confer upon the  Optionee  any
right to  continue  in the  employ of the  Company  or shall  interfere  with or
restrict  in any way the  rights  of the  Company,  which are  hereby  expressly
reserved, to discharge the Optionee at any time for any reason whatsoever,  with
or without cause,  subject to the  provisions of applicable  law. This is not an
employment contract.
     
10.   INCOME TAX WITHHOLDING
a. The Optionee authorizes the Company to withhold in accordance with applicable
law  from  any  compensation  payable  to him or her any  taxes  required  to be
withheld  by  Federal,  state or local laws as a result of the  exercise of this
Option.  The Optionee  agrees to notify the Company  immediately in the event of
any disqualifying disposition (within the meaning of Section 421(b) of the Code)
of the shares acquired upon exercise of an incentive stock option.  Furthermore,
in the event of any determination  that the Company has failed to withhold a sum
sufficient to pay all  withholding  taxes due in connection with the exercise of
this Option, or a disqualifying disposition of the shares acquired upon exercise
of an incentive stock option,  the Optionee agrees to pay the Company the amount
of such deficiency in cash within five (5) days after receiving a written demand
from the Company to do so, whether or not Optionee is an employee of the Company
at that time.  b. At such time as the Optionee is required to pay to the Company
an  amount  with  respect  to  tax  withholding  obligations  as  set  forth  in
subparagraph  a, the  Optionee  may elect  prior to the date the  amount of such
withholding tax is determined to make such payment, or such increased payment as
the Optionee elects to make up to the maximum federal,  state and local marginal
tax rates (including any related FICA obligation) applicable to the Optionee and
the particular  transaction in accordance  with the provisions of Section 9.g of
the Plan.  c. Any adverse  consequences  incurred by an Optionee with respect to
the use of shares of Common  Stock to pay any part of the Option Price or of any
tax in connection with the exercise of an Option, including, without limitation,
any adverse tax consequences arising as a result of a disqualifying  disposition
within the meaning of Section 422 of the Code, shall be the sole  responsibility
of the Optionee.
     
11.   TERMINATION
a. Should optionee voluntarily terminate for Good Cause (as defined below) or be
involuntarily  terminated  for other than Bad Cause (as defined below) more than
twelve (12) months from Optionee's date of employment with the Company, then any
portion of this option  that would have  vested in the six (6) months  following
Optionee's  termination date, shall vest on Optionee's termination date. b. GOOD
CAUSE shall be defined as any of the  following  condition,  which  condition(s)
remain(s) in effect ten (10) days after written notice to the Board of Directors
of the Company from Optionee of such condition(s):
      i. a decrease  in  Optionee's  base salary  and/or a material  decrease in
      Optionee's  standard  management  bonus plan or employee  benefits;  ii. a
      material  reduction in Optionee's title,  authority,  responsibilities  or
      duties, as measured against Optionee's title,  authority or responsibility
      or  duties  immediately  prior to such  reduction;  iii.  Optionee  is not
      promoted to President of the Company within eighteen (18) months following
      his date of employment;  iv. the  relocation of the Optionee's  work place
      for the Company to a location outside Santa Clara County,  California;  or
      v. the Company is in breach of the employment  agreement  (attached)  with
      Optionee.
b. BAD CAUSE shall be defined as:
      i. theft,  dishonesty,  or intentional  falsification of any employment or
      Company records;  ii. intentional and improper disclosure of the Company's
      confidential or proprietary information; or iii. Optionee's conviction for
      any criminal act which materially  impairs  Optionee's  ability to perform
      his duties.

                       RESTRICTED STOCK PURCHASE AGREEMENT


THIS AGREEMENT is made and entered into as of March 30, 1998, between Mission 
West Properties, a California corporation (the "Company") and Michael J. 
Anderson ("Purchaser").

                                R E C I T A L S:

A. Pursuant to the exercise of a stock option (the "Option") granted to 
Purchaser by the Company under the Stock Option Agreement dated March 30, 
1998 (the "Option Agreement"), Purchaser has elected to purchase Two Hundred 
Thousand (200,000) shares of the Company's Common Stock (the "Shares").

B. Purchaser is a key employee of the Company. The securities described in 
this Agreement are being offered and sold pursuant to a written compensatory 
benefit plan of the Company.

NOW, THEREFORE, in consideration of the mutual covenants exchanged, the 
parties agree as follows:

1. PURCHASE AND SALE OF SHARES.

     (a) PURCHASE AND SALE OF SHARES. The Company agrees to sell to 
     Purchaser, and Purchaser agrees to purchase from the Company, Two 
     Hundred Thousand (200,000) shares of the Company's Common Stock (the 
     "Shares"), at a purchase price of Four Dollars and Fifty Cents ($4.50) 
     per share, for a total purchase price of Nine Hundred Thousand Dollars 
     ($900,000). All of the Shares shall be subject to this Agreement and the 
     restrictions herein contained.

     (b) CLOSING. The purchase and sale of the Shares shall be held at the 
     principal office of the Company on the date hereof, or at such other 
     time and place as shall be mutually agreed between Purchaser and the 
     Company. At the closing, Purchaser shall deliver to the Company the 
     total purchase price for the Shares paid in a form and manner authorized 
     by the Option Agreement, and the Company will issue, as promptly  
     thereafter as practicable, a certificate representing the Shares issued 
     in the name of Purchaser. In the event Purchaser delivers his Promissory 
     Note in the form attached hereto as Exhibit A in payment of the purchase 
     price, the following shall apply:

          (i) Purchaser shall assign, transfer and pledge the Shares, or 
          collateral of equivalent value acceptable to the Company, to the 
          Company as security for payment of the Promissory Note in 
          accordance with the provisions of a Security Agreement in the form 
          of Exhibit B attached hereto.

               (ii) In the event Purchaser's employment by the Company is 
<PAGE>

               terminated for any reason whatsoever, including death, the 
               Company shall have the right, upon ninety (90) days' prior 
               written notice to Purchaser, or his legal representative or 
               successor, to accelerate the full payment of the Promissory 
               Note, in which event such payment shall be due and payable to 
               the Company within thirty (30) days after the expiration of 
               the ninety (90)-day period, unless Purchaser is in default 
               under the Promissory Note or the Security Agreement on the 
               date such notice is sent. In the event of such default, the 
               provisions regarding acceleration of payment due under the 
               Promissory Note contained in Section 6 of the Security 
               Agreement shall apply.

2. REPURCHASE OPTION.

     (a) SHARES SUBJECT TO REPURCHASE. Purchaser hereby grants to the Company 
     the option (the "Repurchase Option") to repurchase all or part of the 
     Unvested Shares (as defined in Section 2(b) below) at the price per 
     share paid for them by Purchaser (the "Option Price"), subject to 
     adjustment pursuant to Section 3, upon the occurrences set forth in 
     subSection (c), but only to the extent such Shares have not been 
     released from the Repurchase Option as provided in subSection (b). All 
     of the Shares shall initially be subject to the Repurchase Option.

     (b) RELEASE DATES. The Shares subject to the Repurchase Option shall be 
     released from the Repurchase Option in accordance with the vesting 
     schedule set forth in Section 3(a) of the Option Agreement to the extent 
     and as of the dates provided therein. Shares subject to the Repurchase 
     Option are referred to herein as "Unvested Shares," and Shares which 
     have been released from the Repurchase Option are referred to herein as 
     "Vested Shares."

     (c) OCCURRENCES  PERMITTING EXERCISE.  The Company may exercise the 
     Repurchase Option if during the term of this Agreement any one of the 
     following events (an "Offering Event") takes place: (i) Purchaser shall 
     cease to be employed by the Company (including a Parent or Subsidiary of 
     the Company) for any reason, or no reason, with or without cause, 
     including involuntary termination, death or disability; or (ii) any 
     event occurs which causes the involuntary transfer to creditors or to 
     any other person or entity of all or any part of the Shares still 
     subject to the Repurchase Option at the time of such transfer; or (iii) 
     upon designation by the Company in writing to Purchaser, any 
     acceleration of payment due as provided under the terms of the 
     Promissory Note.

     (d) EXERCISE OF REPURCHASE OPTION. Upon the occurrence of an Offering 
     Event, the Company may exercise the Repurchase Option by delivering 
     personally, or by registered or certified mail, to Purchaser (or the 
     Purchaser's permitted transferee or legal representative, as the case 
     may be), within ninety (90) days after the date of the Offering Event, a 
     notice in writing indicating the Company's election to exercise its 
     Repurchase Option and the number of Shares to be purchased by the 
     Company or the Company's designee, who shall be identified in such 
     notice, and setting forth a date for closing not later than thirty (30) 
     days from the date of giving such notice.

     (e) CLOSING FOR REPURCHASE OF SHARES. The closing for the repurchase of 
     the Shares pursuant to the exercise of the Repurchase Option shall take 
     place at the Company's principal offices. At the closing, the holder of 
     the 

<PAGE>

     certificate(s) representing the Shares being transferred shall deliver 
     said certificate or certificates evidencing the Shares to the Company, 
     duly endorsed for transfer, and the Company (or its designee) shall 
     tender payment of the purchase price for the Shares being purchased. The 
     purchase price shall be payable in full in cash, or by check, provided 
     that the Company may elect to offset against and deduct from any payment 
     of the purchase price any indebtedness then owed by Purchaser to the 
     Company.

3. ADJUSTMENTS.

     (a) GENERAL. If, from time to time during the term of this Agreement: 
     (i) there is any stock dividend, distribution or dividend, stock split, 
     or other change in the character or amount of any of the outstanding 
     securities of the Company; or (ii) there is any consolidation, merger or 
     sale of all, or substantially all, of the assets of the Company; then in 
     such event, any and all new, substituted or additional securities, cash, 
     or other property to which Purchaser is entitled by reason of his 
     ownership of the Shares (the "New Consideration") shall be included in 
     the word "Shares" for all purposes with the same force and effect as the 
     Shares presently subject to the Repurchase Option and other terms of 
     this Agreement, and shall be subject to the Repurchase Option in the 
     same manner and to the same extent as the Unvested Shares with respect 
     to which the New Consideration was provided. While the total Option 
     Price shall remain the same after any such event,  the Option  Price per 
     share shall be appropriately adjusted to reflect any change in the 
     number of shares.

     (b) QUARTERLY DISTRIBUTIONS. Notwithstanding the provisions of 
     subsection (a) above to the contrary, Purchaser shall be entitled to 
     receive and retain dividends or other distributions declared on the 
     Common Stock of the Company by the board of directors quarterly or on 
     any other regular, periodic basis, including but not limited to 
     distributions required for compliance with the provisions of Section 
     857(a) of the Internal Revenue Code of 1986, as amended.

4. RESTRICTIONS ON TRANSFER.

     (a) NO TRANSFER OF SHARES SUBJECT TO REPURCHASE OPTION. Purchaser shall 
     not sell, transfer, pledge, assign or otherwise dispose of any of the 
     Unvested Shares which are subject to the Repurchase Option.

     (b) GIFTS OF SHARES. Notwithstanding any other term of this Section 4, 
     Purchaser may make a gift of all or any part of the Shares to any of 
     Purchaser's parents, spouse, issue, siblings, nephews or nieces or to a 
     trust for the exclusive benefit of any of the foregoing parties. The 
     donee or donees shall hold such Shares subject to all the provisions of 
     this Agreement.

5. ASSIGNMENT OF RIGHTS. The Company may assign its rights under Section 2 
hereof to one or more persons or entities, who shall have the right to so 
exercise such rights in his or its own name and for his or its own account. 
If any such transfer of the Shares requires the consent of any agency 
pursuant to the securities laws of any state, the time periods specified 
herein shall be extended for such period as the necessary request for consent 
to transfer is pending before such agency. All parties agree to cooperate in 
making such request for transfer, and no transfer shall be executed without 
such consent if required by law.

<PAGE>

6. RELEASE OF SHARES FROM REPURCHASE OPTION. The number of Shares subject to 
the Repurchase Option will decline as set forth in Section 2(b), and the 
Repurchase Option shall terminate following the expiration of the notice 
specified in Section 2(d). Subject to the provisions of the Promissory Note 
and the Security Agreement, the Company shall release and deliver to 
Purchaser, from time to time as Purchaser may reasonably request, a 
certificate representing that number of Shares set forth in a written request 
made to the Secretary of the Company, to the extent that such Shares are no 
longer subject to the Repurchase Option. The Company shall cause new 
certificates to be issued as necessary to effectuate the release and delivery 
of such Shares to Purchaser.

7. LEGENDS.

     (a) ENDORSEMENT ON CERTIFICATES. The certificates representing the Shares
     subject to this Agreement shall be endorsed with a legend substantially in
     the following form:

          THE SHARES REPRESENTED BY THIS CERTIFICATE MAY BE TRANSFERRED ONLY 
          IN ACCORDANCE WITH THE TERMS OF A RESTRICTED STOCK PURCHASE 
          AGREEMENT BETWEEN THE COMPANY AND THE REGISTERED HOLDER OR HIS 
          PREDECESSOR IN INTEREST, A COPY OF WHICH IS ON FILE WITH THE 
          SECRETARY OF THE COMPANY. THE AGREEMENT MAY BE INSPECTED AT THE 
          PRINCIPAL OFFICE OF THE COMPANY DURING NORMAL BUSINESS HOURS.

     (b) TERMINATION OF ALL RESTRICTIONS. In the event the restrictions 
     imposed by this Agreement shall be terminated as herein provided, a new 
     certificate or certificates representing the Shares shall be issued, on 
     request, without the legend referred to in Subsection 7(a).

     (c) SECURITIES LAW LEGENDS. Any transfer or sale of the Shares is 
     further subject to all restrictions on transfer imposed by state or 
     federal securities laws. Accordingly, it is understood and agreed that 
     the certificates representing the Shares shall bear any legends required 
     by such state or federal securities laws.

8. PURCHASER'S REPRESENTATIONS. In connection with the purchase of the Shares,
Purchaser hereby represents and warrants to the Company as follows:

     (a) INVESTMENT INTENT; CAPACITY TO PROTECT INTERESTS.  Purchaser is 
     purchasing the Shares solely for his or her own account for investment 
     and not with a view to or for sale in connection with any distribution 
     of the Shares or any portion thereof and not with any present intention 
     of selling, offering to sell or otherwise disposing of or distributing 
     the Shares or any portion thereof in any transaction other than a 
     transaction exempt from registration under the Securities Act of 1933, 
     as amended (the "Act"). Purchaser also represents that the entire legal 
     and beneficial interest of the Shares is being purchased, and will be 
     held, for Purchaser's account only, and neither in whole or in part for 
     any other person. Purchaser either (i) has a pre-existing business or 
     personal relationship with the Company or any of its officers, directors 
     or controlling persons, or (ii) by reason of Purchaser's business or 
     financial experience or the business or financial  experience of  
     Purchaser's professional advisors who are unaffiliated with and who are 
     not compensated by the Company or any affiliate or selling agent of the 
     Company, directly or indirectly, could be reasonably assumed to have the 
     capacity to evaluate the merits and risks of an investment in the 
     Company and to protect Purchaser's own interests in connection with this 
     transaction.
<PAGE>
     (b) INFORMATION CONCERNING COMPANY. Purchaser has heretofore discussed 
     the Company and its plans, operations and financial condition with the 
     Company's officers and has heretofore received all such information as 
     Purchaser has deemed necessary and appropriate to enable the Purchaser 
     to evaluate the financial risk inherent in making an investment in the 
     Shares. Purchaser has received satisfactory and complete information 
     concerning the business and financial condition of the Company in 
     response to all inquiries in respect thereof.

     (c) ECONOMIC RISK. Purchaser realizes that the purchase of the Shares 
     will be a highly speculative investment and involves a high degree of 
     risk, and Purchaser is able, without impairing his or her financial 
     condition, to hold the Shares for an indefinite period of time and to 
     suffer a complete loss of Purchaser's investment.

     (d) RESTRICTED SECURITIES. Purchaser understands and acknowledges that:

          (i) the sale of the Shares has not been registered under the Act, 
          and the Shares must be held indefinitely unless subsequently 
          registered under the Act or an exemption from such registration is 
          available and the Company is under no obligation to register the 
          Shares;

          (ii) the share certificate representing the Shares will be stamped
          with the legends specified in Section 7 hereof; and

          (iii) the Company will make a notation in its records of the 
          aforementioned restrictions on transfer and legends.

     (e) DISPOSITION UNDER RULE 144. Purchaser understands that the Shares 
     are restricted securities within the meaning of Rule 144 promulgated 
     under the Act; that unless the Shares have been issued pursuant to Rule 
     701 promulgated under the Act the exemption from registration under Rule 
     144 will not be available in any event for at least one year from the 
     date of purchase and payment of the Shares (AND THAT PAYMENT BY A NOTE 
     IS NOT DEEMED PAYMENT UNLESS IT IS SECURED BY ASSETS OTHER THAN THE 
     SHARES), and even then will not be available unless: (i) a public 
     trading market then exists for the Common Stock of the Company; (ii) 
     adequate information concerning the Company is then available to the 
     public; and (iii) other terms and conditions of Rule 144 are complied 
     with; and that any sale of the Shares may be made only in limited 
     amounts in accordance with such terms and conditions.

     (f) FURTHER LIMITATIONS ON DISPOSITION. Purchaser agrees that he shall not
     make any disposition of all or any portion of the Shares unless and until:

          (i) (A) There is then in effect a Registration Statement under the 
          Securities Act covering such proposed disposition and such 
          disposition is made in accordance with said Registration Statement; 
          OR, (B)(1) Purchaser shall have notified the Company of the 
          proposed disposition and shall have furnished the Company with a 
          detailed statement of the circumstances surrounding the proposed 
          disposition, (2) Purchaser shall have furnished the Company with an 
          opinion of the Purchaser's counsel to the effect that such  
          disposition will not require registration of such shares under the 
          Securities Act, AND (3) such opinion of Purchaser's counsel shall 
          have been concurred in by counsel for the Company and the Company 
          shall have advised Purchaser of such 

<PAGE>

          concurrence; AND,

          (ii) The Shares proposed to be transferred are no longer subject to
          the Repurchase Option set forth in Section 2 hereof.

9. ESCROW. As security for his faithful performance of the terms of this 
Agreement and to ensure the availability for delivery of Purchaser's Shares 
upon exercise of the Repurchase Option herein provided for, Purchaser agrees 
to deliver to and deposit with Graham & James LLP, legal counsel to the 
Company (the "Escrow Agent"), as Escrow Agent in this transaction, two Stock 
Assignments duly endorsed (with date and number of Shares blank) in the form 
attached hereto as Exhibit C, together with the certificate or certificates 
evidencing the Shares; said documents are to be held by the Escrow Agent 
pursuant to the Joint Escrow Instructions of the Company and Purchaser set 
forth in Exhibit E attached hereto and incorporated by this reference, which 
instructions shall also be delivered to the Escrow Agent at the closing 
hereunder.

10. COMPLIANCE WITH INCOME TAX LAWS.

     (a) WITHHOLDING TAX. Purchaser authorizes the Company to withhold in 
     accordance with applicable law from any compensation payable to him or 
     her any taxes required to be withheld by Federal, state or local laws as 
     a result of the purchase of the Shares. Furthermore, in the event of any 
     determination that the Company has failed to withhold a sum sufficient 
     to pay all withholding taxes due in connection with the purchase of the 
     Shares, Purchaser agrees to pay the Company the amount of such 
     deficiency in cash within five (5) days after receiving a written demand 
     from the Company to do so, whether or not Purchaser is an employee of 
     the Company at that time.

     (b) INTEREST ON NOTE. In the event that any Promissory Note issued by 
     the Purchaser under this Agreement is subject to the provisions of 
     Section 1274 of the Internal Revenue Code of 1986, as amended (the 
     "Code"), and would have original issue discount subject to Section 1272 
     of the Code, the Company and the Purchaser agree to make and file a 
     timely election under Section 1274A(c) of the Code and regulations 
     thereunder to account for all of the interest on such Note on the cash 
     receipts and disbursements method for Federal income tax purposes.

11. ELECTION PURSUANT TO SECTION 83(B) OF INTERNAL REVENUE CODE OF 1986, AS 
AMENDED. Purchaser shall be responsible for filing with the Internal Revenue 
Service an appropriate written notice of election pursuant to Section 83(b) 
of the Code, if Purchaser wishes to make such an election. Purchaser shall 
notify the Company in writing if Purchaser files such an election within 
thirty (30) days of the date of the sale herein contemplated. The Company 
intends, in the event it does not receive from Purchaser evidence of such 
filing, to claim a tax deduction for any amount which would otherwise be 
taxable to Purchaser in the absence of such an election.

12. ENFORCEMENT. Purchaser agrees that a violation on his or her part of any of
the terms of this Agreement (other than those contained in Sections 12 and 13,
above) may cause irreparable damage to the Company, the exact amount of which is
impossible to ascertain, and for that reason agrees that the Company shall be
entitled to exercise its right to effect a repurchase and transfer of the Shares
pursuant to Section 2 hereof or to a decree of specific performance of the terms
hereof or an injunction restraining further violation, said right to be in
addition to any other remedies of said parties.
<PAGE>
13. CONTROLLING PROVISIONS. The Shares are subject to the provisions of the 
Company's 1997 Stock Option Plan, and unless stated otherwise terms defined 
therein have the same meaning when used in this Agreement. To the extent that 
there may be any conflict between the provisions of this Agreement and the 
provisions contained in the Company's Bylaws on the transfer or restriction 
on transfer of Shares, the terms of this Agreement shall be controlling. This 
Agreement may not be modified except by a writing signed by the party to be 
bound.

14. OWNERSHIP, VOTING RIGHTS, DUTIES. This Agreement shall not affect in any 
way the ownership, voting rights or other rights or duties of Purchaser, 
except as specifically provided herein.

15. NOTICES. All notices and other communications required or permitted 
hereunder shall be in writing and shall be deemed effectively given upon 
personal delivery or on the day sent by facsimile transmission if a true and 
correct copy is sent the same day by first class mail, postage prepaid, or by 
dispatch by an internationally recognized express courier service.

16. BINDING EFFECT. This Agreement shall inure to the benefit of the Company 
and its successors and assigns and, subject to the restrictions on transfer 
set forth herein, be binding upon Purchaser, his permitted transferees, 
heirs, legatees, executors, administrators and legal successors, who shall 
hold the Shares subject to the terms hereof.

17. GOVERNING LAW. This Agreement, together with the exhibits hereto, shall 
be governed by and construed in accordance with the laws of the State of 
California, as such laws are applied to contracts entered into by residents 
of such state and performed in such state.

18. ENTIRE AGREEMENT. This Agreement supersedes all previous written or oral 
agreements between the parties regarding the subject matter hereof, and 
constitutes the entire agreement of the parties regarding such subject 
matter. This Agreement may not be modified or terminated except by a writing 
executed by all of the parties hereto.

19. NOT EMPLOYMENT CONTRACT. Nothing in this Agreement shall affect in any 
manner whatsoever the right or power of the Purchaser or the Company to 
terminate Purchaser's employment, for any reason or for no reason, with or 
without cause, subject to the provisions of applicable law. This Agreement is 
not an employment contract.

20. GENDER. The masculine, feminine or neuter pronouns used herein shall be 
interpreted without regard to gender.

21. COUNTERPARTS. This Agreement may be executed in counterparts, each of 
which shall be deemed to be an original, but all of which together shall 
constitute one and the same instrument.

22. SEVERABILITY. If any provision of this Agreement is held by a court of 
competent jurisdiction to be invalid, void or unenforceable, the remaining 
provisions shall nevertheless continue in full force and effect without being 
impaired or invalidated in any way and shall be construed in accordance with 
the purposes and tenor and effect of this Agreement.

IN WITNESS WHEREOF, the parties have executed this Agreement on the date 
first
