                              AMENDED AND RESTATED
                           ARTICLES OF INCORPORATION
                                      OF
                            MISSION WEST PROPERTIES


ARTICLE 1.  The name of this corporation is "Mission West Properties."

ARTICLE 2.  The purpose of this corporation is to engage in any lawful act or 
activity for which a corporation may be organized under the General 
Corporation Law of California other than the banking business, the trust 
company business or the practice of a profession permitted to be incorporated 
by the California Corporations Code.

ARTICLE 3.  This corporation is authorized to issue two classes of stock to 
be designated, respectively, Common Stock ("Common Stock") and Preferred 
Stock ("Preferred Stock"). The number of shares of Common Stock authorized to 
be issued is Two Hundred Million (200,000,000) and the total number of shares 
of Preferred Stock authorized to be issued is Twenty Million (20,000,000).

            The Preferred Stock may be issued from time to time in one or 
more series. The Board of Directors of this corporation is hereby authorized, 
within the limits and restrictions stated in these Amended and Restated 
Articles of Incorporation, to determine or alter the rights, preferences, 
privileges and restrictions granted to or imposed upon any wholly unissued 
series of Preferred Stock, and within the limits stated herein or in any 
resolution or resolutions of the Board of Directors originally fixing the 
number of shares constituting any such series and the designation thereof, to 
increase or decrease the number of shares of any series subsequent to the 
issue of shares of that series, but not below the number of shares of such 
series then outstanding. In case the number of shares of any series shall be 
so decreased, the shares constituting such decrease shall resume the status 
which they had prior to the adoption of the resolution originally fixing the 
number of shares of such series.

            On the effective date of these Amended and Restated Articles of 
Incorporation, all outstanding shares of Common Stock held by each holder of 
record on such date shall be automatically combined at the rate of 
one-for-thirty without any further action on the part of the holders thereof 
or this corporation (the "Reserve Split"). No fractional shares shall be 
issued as a result of the Reverse Split unless such action would result in 
the cancellation of more than ten percent (10%) of the outstanding shares of 
Common Stock. This corporation will pay cash for all fractional shares in an 
amount equal to a price per share of Fifteen Cents ($0.15) prior to the 
combination.

ARTICLE 4.  To the fullest extent permissible under the General Corporation 
Law of California, this corporation is authorized to issue debt securities 
convertible into other debt securities or into shares of the corporation 
within such time and upon the happening of one or more specified events and 
upon such terms and conditions as are fixed by the Board of Directors.

ARTICLE 5.  The liability of the directors of this corporation for monetary 
damages shall be eliminated to the fullest extent permissible under the laws 
of California.

            (a)  Whether by bylaw, agreement or otherwise, the agents of this 
corporation may be provided indemnity by this corporation in excess of the 
indemnity expressly permitted by Section 317 of the California Corporations 
Code for those agents of this corporation for breach of duty to this 
corporation and its stockholders provided, however, that an agent may not be 
indemnified for any acts or omissions or transactions from which a director 
may not be relieved of liability pursuant to this Article or as to 
circumstances in which indemnity is expressly prohibited by Section 317 of 
the California Corporations Code.

            (b)  As used in this Article the term "agents" includes any 
person who is or was a director, officer, employee or other agent of this 
corporation, or is or was serving at the request of this corporation 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 the predecessor corporation of this corporation or of another 
enterprise at the request of such predecessor corporation.
