                          AND ALLOCATION OF LIABILITIES


      THIS AGREEMENT is made by and among the parties identified herein with
reference to the following facts:

                                    RECITALS

A.   ____________________, a Delaware limited partnership (the "Partnership")
     owns and manages certain real property.

B.   _____________, ____________, and _________________ are the limited partners
     of the Partnership, and Mission West Properties, a California corporation
     (the "Company"), is the general partner of the Partnership.

C.   The Partnership is the successor to ________________, a ___________ limited
     partnership, and is governed by the provisions of the Amended and Restated
     Agreement of Limited Partnership of Mission West Properties, L.P. III dated
     as of July 1, 1998, which has revised and restated the limited partnership
     agreement of ______________ (the "Partnership Agreement").

D.   The Partnership has certain liabilities for debt arising from loans to the
     Partnership, some of which are secured by real property of the Partnership
     and others of which are unsecured.

E.   The terms of the Partnership Agreement require the limited partners and the
     general partner to make-up the amount of any capital account deficit
     resulting upon liquidation and winding up of the Partnership under certain
     circumstances ("Deficit Make-Up Provision").

F.   The terms of the Partnership Agreement provide the manner in which
     liability for debt for "nonrecourse debts" (as defined therein) of the
     Partnership is to be shared among the partners for income tax purposes.

G.   As of July 1, 1998, the Partnership has principal indebtedness of
     approximately $___________, under a secured loan from _________, and
     ___________ jointly [or other entity], which they made from funds borrowed
     from Wells Fargo Bank N.A. (the "Lender"), and for which they are
     personally liable (the "Recourse Loan").



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:



                                         PERCENTAGE OF
                    PARTNERS         RECOURSE LOAN ASSUMED
                                           
                 The Company                    0%

                 ______________               ___%

                 ______________               ___%

                 ______________               ___%


(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



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 



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.



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