Item 1. (a) The name of the issuer is Mission West Properties, Inc. (the
"Company").
(b) The principal executive offices of the Company are located at
10050 Bandley Drive, Cupertino, California 95014.
Item 2. Each reporting person and the citizenship or place or organization of
the reporting person are identified on the cover page or cover page
addenda and are incorporated by reference in response to this item.
The address of the principal business office of each reporting person
is 10050 Bandley Drive, Cupertino, California 95014.
The title of class of securities and CUSIP number for the equity
securities covered by this report are incorporated by reference from
the cover page in response to this item.
ITEM 3. IF THIS STATEMENT IS FILED PURSUANT TO RULE 13D-1(B), OR 13D-2(B) OR
(C), CHECK WHETHER THE PERSON FILING IS A:
This statement is being filed pursuant to 13d-1(d).
ITEM 4. OWNERSHIP.
The Company had 19,443,587 shares of Common Stock outstanding as of
December 31, 2006.
Regarding the beneficial ownership of each reporting person, reference
is made to Item 4. of the cover page addendum for each reporting
person and to Item 8., below. The beneficial ownership of shares of
Common Stock by any reporting person is based on such reporting
person's right to exchange O.P. Units for shares of Common Stock upon
certain conditions under an exchange rights agreement with the
Company.
The reporting persons constitute a group because under the Company's
charter and certain agreements among the Company, the reporting
persons and other parties, the ownership interests of the reporting
persons taking into account the shares of the Common Stock that would
be issued upon the exchange of O.P. Units for shares of Common Stock,
are aggregated in determining whether the issuer is subject to certain
restrictions based on such ownership, including:
- the required nomination of two representatives of the reporting
persons to the Company's board of directors
- whether the approval of the reporting person's board
representative of certain actions by the board of directors is
required
- the approval of a sale of substantially all of the assets of the
operating partnerships
- 8 -
In addition, the Company's charter and such agreements limit the
number of shares that can be held at any one time by the reporting
persons in the aggregate to the lesser of 20% of the outstanding
Common Stock and the maximum percentage that individual shareholders
can own, directly or indirectly, under applicable REIT ownership
limits contained in the Internal Revenue Code. Consequently, each of
the reporting persons disclaims beneficial ownership of all shares of
Common Stock in excess of the maximum number of shares that such
reporting person currently has the right to acquire, taking into
account these ownership restrictions.
Furthermore, each reporting person disclaims beneficial ownership of
shares that could be acquired upon the exchange of O.P. Units as to
which such reporting person has no pecuniary interest.
ITEM 5. OWNERSHIP OF FIVE PERCENT OR LESS OF A CLASS.
Not applicable.
ITEM 6. OWNERSHIP OF MORE THAN FIVE PERCENT ON BEHALF OF ANOTHER PERSON.
See responses in Item 4 above and Item 8 below.
ITEM 7. IDENTIFICATION AND CLASSIFICATION OF THE SUBSIDIARY WHICH ACQUIRED THE
SECURITY BEING REPORTED ON BY THE PARENT HOLDING COMPANY OR CONTROL
PERSON.
Not applicable.
ITEM 8. IDENTIFICATION AND CLASSIFICATION OF MEMBERS OF THE GROUP.
This schedule is filed pursuant to Rule 13d-1(d). The responses to
Items 2(a)-(c) identify each of the persons filing this statement. See
Exhibit 99.
ITEM 9. NOTICE OF DISSOLUTION OF GROUP.
Not applicable.
