                               GENERAL INFORMATION

     This Proxy  Statement is furnished in connection  with the  solicitation by
the Board of Directors of Mission West Properties,  Inc., a Maryland corporation
(the "Company"),  of proxies,  in the accompanying  form, to be used at the 2002
Annual Meeting of Stockholders to be held at 10:00 a.m., PDT, on May 23, 2002 at
10050  Bandley  Drive,  Cupertino,  California  95014  and any  postponement  or
adjournments thereof (the "Meeting").

     This Proxy  Statement  and the  accompanying  proxy are being  mailed on or
about  April 30, 2002 to all  stockholders  entitled to notice of and to vote at
the Meeting.

                       SOLICITATION AND VOTING PROCEDURES

     Shares represented by valid proxies in the form enclosed,  received in time
for use at the Meeting and not revoked at or before the  Meeting,  will be voted
at the  Meeting.  The  presence,  in  person or by proxy,  of the  holders  of a
majority of the  outstanding  shares of the Company's  common  stock,  par value
$.001 per share  ("Common  Stock"),  is necessary to  constitute a quorum at the
Meeting.  Holders  of  Common  Stock are  entitled  to one vote per share on all
matters.  The Company will  tabulate  stockholder  votes,  and an officer of the
Company will tabulate  votes cast in person at the Meeting.  With respect to the
tabulation of proxies for purposes of  constituting  a quorum,  abstentions  are
treated as present,  but will not be counted as votes cast at the  Meeting  with
respect to any proposal and will have no effect on the result of the vote.

     Assuming the presence of a quorum,  the affirmative  vote of a plurality of
the votes cast at the Meeting and  entitled to vote is required for Proposal No.
1 regarding the election of each director. An affirmative vote of the holders of
a majority  of the votes cast  affirmatively  or  negatively  at the  Meeting is
necessary  for  approval  of  Proposal  No.  2  to  ratify  the  appointment  of
independent auditors.  All proxies will be voted as specified on the proxy cards
submitted by stockholders,  if the proxy is properly executed and is received by
the  Company  before the close of voting at the  Meeting or any  adjournment  or
postponement  thereof. If no choice has been specified,  a properly executed and
timely proxy will be voted for  Proposals  Nos. 1 and 2, which are  described in
detail elsewhere in this Proxy Statement.

     The close of  business  on April 17, 2002 has been fixed as the record date
for  determining  the  stockholders  entitled  to  notice  of and to vote at the
Meeting.  As of that date,  the Company had  17,463,329  shares of Common  Stock
outstanding and entitled to vote.

     The cost of  soliciting  proxies,  including  expenses in  connection  with
preparing  and mailing this Proxy  Statement,  will be borne by the Company.  In
addition,   the  Company  will  reimburse  brokerage  firms  and  other  persons
representing  beneficial owners of Common Stock for their expenses in forwarding
proxy material to such beneficial owners. Solicitation of proxies by mail may be
supplemented  by telephone,  telegram,  telex and other  electronic  means,  and
personal solicitation by the directors, officers or employees of the Company. No
additional  compensation  will be paid to  directors,  officers or employees for
such solicitation.

     The Company's  Annual  Report on Form 10-K for the year ended  December 31,
2001 is being mailed to the stockholders with this Proxy Statement.

                      VOTING ELECTRONICALLY OR BY TELEPHONE

     A number  of  brokerage  firms and  banks  are  participating  in a program
provided through ADP Investor  Communication  Services that offers telephone and
Internet  voting  options.  If your shares are held in an account at a brokerage
firm or bank participating in the ADP program, you may authorize and direct your
vote of those  shares by calling  the  telephone  number  which  appears on your
voting form or though the Internet in accordance with  instructions set forth on
the voting form. The  Authorization  to vote your shares through the ADP program
must be received by midnight on May 22, 2002.

     The Internet and telephone  voting  procedures are designed to authenticate
stockholders'   identities,   to  allow   stockholders   to  communicate   their
authorization  of a  proxy  to vote  their  shares  and to  confirm  that  their
instructions  have been properly  recorded.  The

                                     - 1 -


Company has been advised by its counsel that the  procedures  that have been put
in place are consistent with the  requirements  of applicable law.  Stockholders
communicating  voting  authorization  via  the  Internet  through  ADP  Investor
Communication Services should understand that there may be costs associated with
electronic  access,  such as usage  charges from Internet  access  providers and
telephone companies, that would be borne by the stockholder.

                             REVOCABILITY OF PROXIES

     You can revoke  your proxy at any time  before the voting at the Meeting by
sending a properly  signed written notice of your revocation to the Secretary of
the Company,  by submitting  another  proxy that is properly  signed and bears a
later date or by attending  the Meeting and voting in person.  Attendance at the
Meeting  will not  itself  revoke  an  earlier  submitted  proxy.  Requests  for
additional  copies  of the  Annual  Report  and Proxy  Statement  may be made by
calling the Company at (408) 725-0700.  You should direct any written notices of
revocation,  requests  for  additional  copies of the  Annual  Report  and Proxy
Statement,  and related correspondence to: Mission West Properties,  Inc., 10050
Bandley Drive, Cupertino, California 95014, Attention: Secretary.

NUMBER TERMS AND ELECTION OF DIRECTORS

     The Company's Bylaws currently provide for a Board of Directors  consisting
of five directors. Each director serves for a term of one year or until the next
annual meeting at which  directors are elected and the  director's  successor is
elected  and  qualifies.  In the  election of  directors,  each  stockholder  is
entitled to one vote for each share of Common Stock held by such stockholder.

MEETINGS OF DIRECTORS

     Under the Company's Articles of Amendment and Restatement,  or Charter, its
Bylaws and  contracts  with the "Berg  Group,"  which  consists of Carl E. Berg,
Clyde  J.  Berg,  the  members  of  their  respective  immediate  families,  and
affiliated  entities  owning limited  partnership  interests,  or O.P. Units, in
Mission West Properties,  L.P.,  Mission West  Properties,  L.P. I, Mission West
Properties,  L.P.  II, or Mission  West  Properties,  L.P.  III (the  "Operating
Partnerships"),  the Berg Group has special  rights with  respect to meetings of
the Board of Directors.  A quorum for any meeting  requires the presence of Carl
E. Berg,  or in the event of his death,  disability or other event which results
in his  ceasing  to be  director,  the  presence  of  someone  who Mr.  Berg has
designated to replace him ("Berg Designee").  With written consent from Mr. Berg
or the Berg Designee, meetings of the Board of Directors may be held without the
presence of either of them. Mr. Berg is obligated to submit a written  statement
identifying the Berg Designee to the Company from time to time and may amend the
statement  at his sole  discretion.  In  addition,  a  majority  of the Board of
Directors which includes Mr. Berg or the Berg Designee, is required for approval
of any amendment 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. These special provisions will remain in effect as long as the Berg
Group collectively owns at least 15% of the voting stock of the Company computed
on a diluted,  or "Fully  Diluted",  basis  taking into account all voting stock
issuable upon the exercise of all  outstanding  warrants,  options,  convertible
securities and other rights to acquire voting stock of the Company, and all O.P.
Units  exchangeable  or redeemable for Common Stock or other voting stock of the
Company  without  regard  to any  percentage  ownership  limit  set forth in the
Charter or Bylaws, or by agreement.

COMPENSATION OF DIRECTORS

     The  Company  pays each  director  who is not an officer or employee of the
Company a fee for serving as  director.  The annual fee is equal to $15,000 plus
$1,000 for  attendance  (in person or by telephone) at each meeting of the Board
of Directors, excluding committee meetings. Officers of the Company who are also
directors do not receive any directors' fees.

     Each non-employee  member of the Board of Directors who became or becomes a
member of the Board of Directors  after November 10, 1997, the date on which the
1997 Stock Option Plan (the "Option Plan") was approved by the  stockholders  of
the  Company,  automatically  receives 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 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
remains a director.

COMMITTEES OF THE BOARD OF DIRECTORS AND MEETINGS

     The  Company's  Board of  Directors  has  standing  Audit and  Compensation
Committees.  The Audit  Committee  currently has three members:  John C. Bolger,
William A. Hasler and Lawrence B. Helzel. The Compensation  Committee  currently
has the same three members.

     The Board of Directors also has an Independent  Directors Committee,  which
is also  comprised  of Messrs.  Bolger,  Hasler and Helzel.  This  Committee  is
responsible  for  reviewing and acting upon  proposed  transactions  between the
Company  and  members  of the Berg Group  under the terms of certain  agreements
between the Company and such Berg Group members. See "Certain  Relationships and
Related Transactions."

     During the year ended  December 31, 2001,  there were four  meetings of the

     annual  appreciation  rates  specified by the SEC. These increases in value
     are based on speculative assumptions for illustrative purposes only and are
     not  intended  to forecast  possible  future  appreciation,  if any, of the
     Company's stock price.

     employee of the Company with respect to the fiscal year ended  December 31,

CONTRACTUAL AND OTHER CONTROL ARRANGEMENTS

     SPECIAL BOARD VOTING PROVISIONS. The Charter and Bylaws provide substantial
control rights for the Berg Group.  These rights include a requirement  that Mr.
Berg or his designee as director approve certain fundamental  corporate actions,
including amendments to the Charter and Bylaws and any merger,  consolidation or
sale of all or substantially all of our assets. In addition,  the Bylaws provide
that a quorum  necessary to hold a valid meeting of the board of directors  must
include Mr. Berg or his  designee.  The rights  described  in the two  preceding
sentences  apply only as long as the Berg Group  members  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. In addition,  directors  representing more than 75% of the entire
board  of  directors  must  approve  other  significant  transactions,  such  as
incurring debt above certain amounts,  acquiring assets and conducting  business
other than through the Operating Partnerships.

     BOARD OF DIRECTORS REPRESENTATION. The Berg Group members have the right to
designate  two of the director  nominees  submitted by the Board of Directors to
stockholders  for  election,  as  long  as the  Berg  Group  members  and  their
affiliates, other than the Company and the Operating Partnerships,  beneficially
own, in the aggregate, at least 15% of our outstanding shares of Common Stock on
a Fully Diluted basis. If the Fully Diluted  ownership of the Berg Group members
and their  affiliates  is less than 15% but is at least 10% of the Common Stock,
the Berg Group members have the right to designate one of the director  nominees
submitted by the Board of Directors to stockholders  for election.  Its right to
designate  director  nominees  affords  the Berg Group  substantial  control and
influence over the management and direction of our corporation.

     SUBSTANTIAL  OWNERSHIP  INTEREST.  The Berg Group currently owns O.P. Units
representing  approximately  75.4%  of the  equity  interests  in the  operating
partnerships.  The O.P.  Units may be  converted  into  shares of Common  Stock,
subject to  limitations  set forth in the  Charter  (including  an  overall  20%
ownership limitation), and other agreements with the Berg Group. Upon conversion
these shares would  represent  voting  control of the Company.  The Berg Group's
ability  to  exchange  its O.P.  Units  for  Common  Stock  permits  it to exert
substantial influence over the management and direction of the Company.

     LIMITED PARTNER APPROVAL RIGHTS. Mr. Berg and other limited partners of the
Operating Partnerships,  including other members of the Berg Group, may restrict

all or substantially all of the assets of the Operating Partnerships and certain
mergers and business  combinations  resulting in the complete disposition of all
O.P. Units;  (ii) the issuance of limited  partnership  interests  senior to the
O.P. Units as to distributions,  assets and voting; and (iii) the liquidation of
the Operating Partnerships.

COMPARISON OF SHAREHOLDER RETURN ON INVESTMENT

     The following  line graph  compares the change in the Company's  cumulative
stockholder  return on its shares of Common Stock to the cumulative total return
of the NAREIT  Equity REIT Total Return Index  ("NAREIT  Equity  Index") and the
Standard & Poor's 500 Stock Index ("S & P 500 Index") from  December 31, 1998 to
December 31, 2001. The line graph starts December 31, 1998; however, the Company
started  trading under the Berg Group  ownership on December 8, 1998.  The graph
assumes that the value of the investment in the Company's  Common Stock was $100
at December 31, 1998 and that all dividends were reinvested.  The Common Stock's
price on December 31, 1998 was $6.75. The Company obtained the information about
the NAREIT Equity Index and S & P 500 Index from each entity  respectively,  and
has assumed that the information is reliable, but cannot assume its accuracy.

                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

     Set forth below is a summary of certain material transactions since January
1, 2001  between  the Company and any of its  directors,  executive  officers or
holders of more than 5% of the Company's  Common  Stock,  or between the Company
and persons in which directors,  executive  officers or such  stockholders  have
direct or indirect material interests.

PROPERTY  ACQUISITIONS  AND FINANCIAL  TRANSACTIONS  BETWEEN THE COMPANY AND THE
BERG GROUP

     Through a series of  transactions  in 1997 and 1998, the Company became the
vehicle for substantially  all of the Silicon Valley R&D property  activities of
the Berg Group,  which includes Mr. Berg, his brother Clyde J. Berg,  members of
their  families  and a number of  entities  in which  they have  controlling  or
substantial  ownership  interests.  The  Company  owns these  former  Berg Group
properties,  as  well as the  rest  of its  properties,  through  the  Operating
Partnerships,  of which the Company is the sole general partner. Through various
property  acquisition  agreements with the Berg Group, the Company has the right
to purchase,  on  pre-negotiated  terms, R&D and other types of office and light
industrial  properties  that the Berg Group develops in the future in the states
of California, Oregon and Washington.

     PENDING  PROJECTS  ACQUISITION  AGREEMENT.  In December  1998,  the Company
entered into the pending projects acquisition agreement with members of the Berg
Group,  under  which  the  Company  agreed to  acquire,  through  the  Operating
Partnerships,  approximately  1.0 million  square feet upon the  completion  and
leasing of identified pending  development  projects owned by certain members of
the Berg Group.  The pending  projects  acquisition  agreement was terminated in
December 2000 when the last property contemplated for development was completed,
leased, and purchased by the Company.

     BERG LAND HOLDINGS OPTION AGREEMENT.  In December 1998, the Company entered
into the Berg land holdings option  agreement  under which the Company,  through
the Operating Partnerships, has the option to acquire any future R&D, office and
industrial  property  developed  by the Berg  Group on land  currently  owned or
optioned, or acquired for these purposes in the future,  directly or indirectly,
by Carl E. Berg or Clyde J. Berg. The principal  terms of the agreement  include
the following:

- -    So long as the Berg  Group  members  and their  affiliates  own or have the
     right to acquire shares  representing at least 65% of our Common Stock on a
     Fully  Diluted  basis the  Company  will have the  option  to  acquire  any
     building  developed  by any member of the Berg Group on the land subject to
     the  agreement  at such  time as the  building  has been  leased.  Upon the
     exercise of the option, the option price will equal the sum of:

     (1)  the full construction cost of the building; plus
     (2)  10% of the full construction cost of the building; plus
     (3)  interest  at LIBOR plus  1.65% on the amount of the full  construction
          cost of the building for the period from the date funds were disbursed
          by the developer to the close of escrow; plus
     (4)  the original  acquisition cost of the parcel on which the improvements
          will be constructed; plus
     (5)  10% per annum of the amount of the  original  acquisition  cost of the
          parcel from the later of January 1, 1998 and the seller's  acquisition
          date, to the close of escrow; minus
     (6)  the aggregate  principal  amount of all debt  encumbering the acquired
          property,  or a lesser amount as approved by the Independent Directors
          Committee.

- -    The  acquisition  cost,  net of any debt,  will be payable in cash, or O.P.
     Units  valued at the  average  closing  price of the Common  Stock over the
     30-trading-day  period  preceding the acquisition or in cash, at the option
     of the Berg Group.

- -    The Company must assume all property tax assessments.

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

- -    All  action  taken by the  Company  under  the Berg  land  holdings  option
     agreement must be approved by a majority of the members of the  Independent
     Directors Committee.

     In January 2002, we acquired an approximately  125,000 rentable square foot
newly  constructed  R&D  property  located at 5345  Hellyer  Avenue in San Jose,
California under the Berg land holdings option agreement.  The total acquisition
price for this  property  was  approximately  $13.7  million.  We acquired  this
property  by  borrowing  $7.5  million  under the Berg  Group line of credit and
issuing 502,805 O.P. Units to various members of the Berg Group.

     OTHER  COVENANTS.  The  acquisition  agreement,  Berg land holdings  option
agreement and supplemental agreement to which the Company and the Berg Group, or
Carl  E.  Berg  and  Clyde  J.  Berg,  individually  are  parties  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,  office  or
industrial  properties,  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  of  the  projects  subject  to  the  pending  projects  acquisition
agreement or completed  buildings  acquired  pursuant to the Berg land  holdings
option agreement or the  supplemental  agreement.  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 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,
including for these purposes all shares  issuable upon exercise of the rights to
exchange O.P. Units for Common Stock.

     In  addition,  transactions  between the Company and any member of the Berg
Group, or an entity in which a member of the Berg Group holds at least 5% of the
equity interests,  including the Company's election to issue Common Stock or pay
cash in exchange for O.P. Units tendered by the Berg Group are subject to review
and  approval  by  the  Independent   Directors  Committee.   Aside  from  these
restrictions,  the  Berg  Group  is  generally  free  to  conduct  its  business
activities  and will not be required to seek the approval of such  activities or
refer business  opportunities to the Company,  nor will it have any liability to
the Company for its failure to do so.

     ISSUANCE AND  ASSUMPTION  OF DEBT.  As of March 31,  2002,  the Company was
liable for loans aggregating  approximately  $85,089,000 and $11,300,000 payable
to  the  Berg  Group  under  a  secured  line  of  credit  and  mortgage   loan,
respectively.  The Berg Group  line of credit is  secured by eleven  properties,
bears  interest at LIBOR plus 1.30  percent,  and the maturity date has recently
been  extended to March 2003.  The mortgage  loan is secured by two  properties,
bears interest at 7.65 percent, and matures in June 2010.

     LEASE FROM BERG GROUP. The Company leases its executive offices from Berg &
Berg  Enterprises,  Inc. For the year ended  December 31, 2001, the Company paid
$87,840 to Berg & Berg Enterprises,  Inc. under the terms of the lease agreement
for its executive offices.

             SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

     Section 16(a) of the Securities Exchange Act of 1934, as amended,  requires
the Company's  directors  and  officers,  and persons who own more than 10% of a
registered class of the Company's equity securities, to file with the Securities
and Exchange  Commission (the "SEC") initial reports of ownership and reports of
changes in ownership of Common Stock and other equity securities of the Company.
Directors,  officers  and greater  than ten percent  holders are required by SEC
regulation  to furnish the Company with copies of all Section 16(a) reports they
file.

     To the  Company's  knowledge,  based  solely on review of the copies of the
above-mentioned  reports  furnished  to the Company and written  representations
regarding all reportable transactions, during the fiscal year ended December 31,
2001,  all  Section  16(a)  filing  requirements  applicable  to its  directors,
officers and greater than ten percent holders were complied with on time, except
that Carl E. Berg and  certain  members of the Berg  Group did not  timely  file
seven  reports on Form 4 that may have been due with  respect to  acquired  O.P.
Units issued pursuant to the Berg land holdings option agreement.


                     REPORT ON EXECUTIVE COMPENSATION BY THE
                COMPENSATION COMMITTEE OF THE BOARD OF DIRECTORS

     The Compensation  Committee (the  "Committee")  comprises three independent
members  of the  Board  of  Directors.  The  Company's  Board of  Directors  has
delegated  to the  Committee  responsibility  for  reviewing,  recommending  and
approving  the  Company's  compensation  policies  and  benefits  programs.  The
Committee also has the principal  responsibility  for the  administration of the
company's  stock plans,  including  approving  stock option  grants to executive
officers.

COMPENSATION PHILOSOPHY

     The  Company's  executive  compensation  policy is  designed to attract and
retain qualified executive personnel by providing  executives with a competitive
total  compensation  package  based in large part on their  contribution  to the
financial  and  operational  success of the Company,  the  executive's  personal
performance  and  increases in  stockholder  value as measured by the  Company's
stock price.

COMPENSATION PROGRAM

The compensation  package for the Company's  executive  officers consists of the
following three components:

     BASE SALARY.  The Committee  determines  the base salary of each  executive
based on the  executive's  scope of  responsibility,  past  accomplishments  and
experience and personal performance,  internal comparability  considerations and
data regarding the prevailing  compensation  levels for comparable  positions in
relevant  competing  executive  labor markets.  The Committee may give different
weight to each of these factors for each executive, as it deems appropriate.  In
selecting   comparable   companies  for  the  purpose  of  setting   competitive
compensation for the Company's executives,  the Committee considers many factors
not  directly  associated  with  stock  price  performance,  such as  geographic
location,   annual   revenue  and   profitability,   organizational   structure,
development stage and market capitalization.

     ANNUAL  INCENTIVE  COMPENSATION.  At the present time, the Company does not
have an annual incentive  compensation program in place.  However, the Committee
may in the future at the Committee's  discretion  institute an annual  incentive
program.

     STOCK  OPTIONS.  The  Committee  believes  that  granting  stock options to
executives  and other key  employees  on an  ongoing  basis  gives them a strong
incentive to maximize stockholder value and aligns their interests with those of
other stockholders.  The Committee  determines stock option grants to executives
and has  authorized  the Company's CEO to determine  stock option grants for all
other employees,  subject to the Committee's approval of total share allocations
from the Company's  option plan. In determining the size of stock option grants,
the   Committee   considers   the   executive's   current   position   with  and
responsibilities  to the Company,  potential  for increased  responsibility  and
promotion  over the option  term,  tenure with the Company  and  performance  in
recent periods,  as well as the size of comparable  awards made to executives in
similar positions in competing  executive labor markets.  Generally,  each stock
option grant allows the  executive to purchase  shares of the  Company's  Common
Stock at a price per share  equal to the market  price on the date the option is
granted,  but the  Committee  has the power to grant options at a lower price if
considered  appropriate  under  the  circumstances.   Each  stock  option  grant
generally becomes exercisable,  or vests, in installments over time,  contingent
upon the executive's continued employment with the Company.

                                     - 13 -


     COMPENSATION OF CHIEF EXECUTIVE OFFICER. The annual salary for Mr. Berg was
set in 1997 and first  became  payable  in 1998.  The  Committee  has no plan to
adjust his compensation.

     COMPLIANCE WITH INTERNAL REVENUE CODE SECTION 162(M). Section 162(m) of the
Internal  Revenue Code  generally  disallows a tax  deduction  to  publicly-held
companies for compensation  paid to certain  executive  officers,  to the extent
that  compensation  paid to the officer  exceeds $1 million during the Company's
taxable year. the compensation paid to the company's  executive officers for the
year ended December 31, 2001 did not exceed the $1 million limit per officer. In
addition,  the Company's 1997 Stock Option Plan and executive  incentive  option
grants have been structured so that any compensation deemed paid to an executive
officer in connection with the exercise of his or her  outstanding  options with
an  exercise  price per share  equal to the fair  market  value per share of the
Common  Stock on the grant date will qualify as  performance-based  compensation
that will not be subject to the $1 million limitation.  It is very unlikely that
the cash compensation  payable to any of the Company's executive officers in the
foreseeable  future will approach the $1 million  limit,  and the Committee does
not expect to take any action at this time to modify cash  compensation  payable
to the Company's executive officers to avoid the application of Section 162(m).

           COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

     The Compensation Committee of the Board of Directors was formed in December
1998 and currently is comprised of Messrs. John C. Bolger, William A. Hasler and
Lawrence B. Helzel.  None of these  individuals were at any time during 2001, or
at any other time, an officer or employee of the Company.  No executive  officer
of the Company  serves as a member of the  Compensation  Committee  of any other
entity  that has one or more  executive  officers  serving  as a  member  of the
Company's Board of Directors or Compensation Committee.


                             AUDIT COMMITTEE REPORT

     The Audit Committee reviews,  acts on and reports to the Board with respect
to various  auditing and  accounting  matters,  including  the  selection of the
Company's  independent public accountants,  the scope of the annual audits, fees
to be  paid to the  Company's  accountants,  the  performance  of the  Company's
accountants, the audit report on the Company's consolidated financial statements
following  completion of the audit and the  accounting  practices of the Company
with  respect  to  internal  accounting  and  financial  controls.  The Board of
Directors of the Company adopted an Audit Committee Charter on June 9, 2000. The
Audit  Committee is currently  comprised of Messrs.  John C. Bolger,  William A.
Hasler, and Lawrence B. Helzel, all of whom are independent. The Audit Committee
met three times during fiscal year 2001.

     The Audit  Committee  has  reviewed  and  discussed  the audited  financial
statements of the Company for fiscal year 2001 with management and the Company's
independent  public  accountants,   PricewaterhouseCoopers   LLP  ("PWC").   The
Committee  discussed  with PWC matters  required to be discussed by Statement on
Auditing  Standards  No. 61  (Communication  with Audit  Committees).  The Audit
Committee  was  also  provided  by  PWC  the  written  disclosures  required  by
Independence Standards Board Standard No. 1 (Independence Discussions with Audit
Committees), and the Committee discussed with PWC that firm's independence.

     Based on the discussions  with PWC concerning the audit,  the  independence
discussions and the financial  statement  review,  and such other matters deemed
relevant and appropriate by the Audit Committee, the Audit Committee recommended
to the Board that the Company's  financial  statements for the fiscal year ended

William A. Hasler                    Director                                                                      1998

     In  accordance  with the Company's  Bylaws,  it is a  qualification  of two
directors that they be nominated by the Berg Group and that one such director be
Carl E. Berg or the Berg  Designee as long as the Berg Group and its  affiliates
(other than the Company and the Operating  Partnership)  own at least 15% of the
Fully Diluted  number of shares.  The Company has been advised by Mr. Berg,  who
represents  the Berg  Group,  that he will be the only Berg  Group  nominee  for
election at this meeting.

     A  plurality  of the votes cast at the  Meeting is  required  to elect each
nominee as a director.  Unless  authority to vote for any of the nominees  named
above is withheld,  the shares  represented  by the enclosed proxy will be voted
FOR the election as directors of such nominees. Each person nominated has agreed
to serve if elected,  and the Board of  Directors  has no reason to believe that
any nominee will be unavailable or will decline to serve. In the event, however,
that any nominee is unable or declines to serve as a director at the time of the
Meeting,  the proxies  will be voted for any nominee  who is  designated  by the
current Board of Directors to fill the vacancy.

     THE  BOARD  OF  DIRECTORS  RECOMMENDS  THAT THE  STOCKHOLDERS  VOTE FOR THE
ELECTION OF ALL OF THE ABOVE NOMINEES.

            --------------------------------------------------------
                                 PROPOSAL NO. 2:
                         INDEPENDENT PUBLIC ACCOUNTANTS
            --------------------------------------------------------

     The  Board  of  Directors   has   appointed   PricewaterhouseCoopers   LLP,
independent public accountants, to audit the financial statements of the Company
for the year ending December 31, 2002. The Board of Directors  proposes that the
stockholders ratify this appointment.  The Company expects that  representatives
of  PricewaterhouseCoopers  LLP ("PWC")  will be present at the Annual  Meeting,
will have the  opportunity to make a statement if they desire to do so, and will
be available to respond to appropriate questions.

     PWC were the  Company's  independent  accountants  for the last fiscal year
ended  December 31, 2001.  The Company  incurred  the  following  fees for PWC's
services last year:

     AUDIT FEES.  The  aggregate  fees billed by PWC for  professional  services
rendered for the audit of the  Company's  annual  financial  statements  for the
fiscal year ended  December  31,  2001 and the reviews of the interim  financial
statements  included  in the  Company's  Quarterly  Reports on Form 10-Q for the
fiscal year ended December 31, 2001 were approximately $100,000.

     FINANCIAL  INFORMATION SYSTEMS DESIGN AND IMPLEMENTATION FEES. During 2001,
PWC did not render any services to the Company related to financial  information
systems design and implementation.

     ALL OTHER FEES. The aggregate  fees billed by PWC for  compliance  services
rendered to the Company,  other than the services  described  under "Audit Fees"
and  "Financial  Information  Systems Design and  Implementation  Fees," for the
fiscal year ended December 31, 2001 were approximately $7,000.

     In the event that stockholders fail to ratify the appointment, the Board of
Directors will reconsider its selection.  Even if the selection is ratified, the
Board of Directors, in its discretion, may direct the appointment of a different
independent  accounting  firm  at any  time  during  the  year if the  Board  of
Directors  determines  that  such  a  change  would  be in  the  Company's  best
interests.

     The  affirmative  vote of a  majority  of the votes cast  affirmatively  or
negatively  at  the  Meeting  is  required  to  ratify  the  appointment  of the
independent public accountants.

     THE  BOARD  OF  DIRECTORS  RECOMMENDS  THAT THE  STOCKHOLDERS  VOTE FOR THE
PROPOSAL TO RATIFY THE SELECTION OF  PRICEWATERHOUSECOOPERS  LLP TO SERVE AS THE
COMPANY'S INDEPENDENT PUBLIC ACCOUNTANTS FOR THE YEAR ENDING DECEMBER 31, 2002.
