EXHIBIT 10.29.2

                            CHANGE IN TERMS AGREEMENT

     This  Change  in  Terms  Agreement  (this  "Agreement")  is  made as of and
delivered on July 22, 2005,  by and between  Mission  West  Properties,  Inc., a
Maryland corporation ("Borrower"), and Cupertino National Bank (the "Bank").

                                    RECITALS

     A. As of July  12,  2002,  the  Bank  and  Borrower  entered  into  certain
agreements (the "2002 Loan Documents")  including but not limited to a Revolving
Credit Loan  Agreement  pursuant to which the Bank agreed,  subject to the terms
and conditions set forth therein, to lend up to the sum of Forty Million Dollars
($40,000,000.00) to Borrower, pursuant to which the Bank lent certain amounts to
Borrower,  and pursuant to which Borrower  agreed to repay the loan on or before
November 2, 2004.

     B. As of November 2, 2004,  at  Borrower's  request,  the Bank and Borrower
entered into certain agreements (the "Loan Documents") including but not limited
to a Revolving  Credit Note and a Revolving  Credit Loan  Agreement (the "Credit
Agreement")  pursuant  to which,  subject  to the terms  and  conditions  stated
therein,  the Bank agreed to refinance  the amounts due and owing under the 2002
Loan  Documents  and continue to lend to Borrower and pursuant to which the Bank
lent certain  amounts to Borrower.  Also as of November 2, 2004,  MWP executed a
Continuing Guaranty (the "MWP Guaranty")  guarantying  Borrower's obligations to
the Bank. Unless expressly stated to the contrary herein,  all capitalized terms
used herein shall have the meaning ascribed to them in the Loan Documents.

     C. Pursuant to the Loan  Documents,  Borrower is currently  indebted to the
Bank  in the  principal  sum  of  Twenty-Three  Million  Nine  Hundred  Thirteen
Thousand,  Ninety-Five  and 24/100 Dollars  ($23,913,095.24),  plus interest and
fees thereon.

     D. Included  among the Loan Documents is a  Non-Encumbrance  Agreement (the
"Non-Encumbrance  Agreement")  pursuant to which Borrower and MWP agreed,  among
other things,  not to encumber,  transfer,  or  hypothecate  any of the MWP Pool
Properties.  MWP now desires to refinance two of such properties,  that property
located  at  5325-5345  Hellyer  Avenue,  San  Jose,  California  (the  "Hellyer
Property") and that property  located at 1768 Automation,  San Jose,  California
(the  "Automation  Property"),  and Borrower has requested that the Bank release
such properties from the MWP Pool Properties in the Non-Encumbrance Agreement.

     E. Pursuant to the Loan Documents,  Borrower is not entitled to borrow more
than Forty Million Dollars  ($40,000,000.00) or more than fifty percent (50%) of
the total combined Value of the MWP Pool Properties. If the Hellyer Property and
the  Automation  Property are released  from the MWP Pool  Properties,  the only
property  remaining within the MWP Pool Properties will be that property located
at 5970 Optical  Court,  San Jose,  California  (the  "Optical  Property"),  and
Borrower  will be  over-advanced  by the sum of  Thirteen  Million  One  Hundred
Twenty-Five Thousand Seven Hundred Thirty-Five Dollars ($13,125,735.00).

     F. The Bank is  willing,  subject  to the  terms and  conditions  set forth
herein, to release the Hellyer Property and the Automation Property.

     In  consideration  of the premises and the mutual promises herein contained
and in reliance upon Borrower's representations and warranties set forth herein,
Borrower and the Bank agree as follows:

                                    AGREEMENT
