Partnership (the 'Partnership') as of June 30, 1997, and the results of its
operations for the six and three months ended June 30, 1997 and 1996 and its
cash flows for the six months ended June 30, 1997 and 1996. However, the
operating results for the interim periods may not be indicative of the results
expected for the full year.

financial statements prepared in accordance with generally accepted accounting
principles have been omitted. It is suggested that these financial statements be

   PBP is not being paid on a current basis for general and administrative
expenses other than printing costs. During the six and three months ended June
30, 1997, PBP was reimbursed approximately $100,000 and $50,000, respectively,
which was applied to prior years' general and administrative expenses due. At
June 30, 1997 and December 31, 1996, the total liability outstanding to PBP was
approximately $644,000 and $705,000, respectively. At June 30, 1997, the total
liability outstanding to Glenborough was approximately $39,000.
 
   The Partnership maintains an account with the Prudential Institutional
Liquidity Portfolio Fund, an affiliate of PBP, for investment of its available
cash in short-term instruments pursuant to the guidelines established by the
Partnership Agreement.
 
   Prudential Securities Incorporated ('PSI'), an affiliate of PBP, owns 180
depositary units at June 30, 1997.

      ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                           AND RESULTS OF OPERATIONS
 
Liquidity and Capital Resources
 
   The Partnership generated cash from operations of $861,000 for the six months
ended June 30, 1997. During the six months ended June 30, 1997, the Partnership
disbursed approximately $336,000 for building and tenant improvements, primarily
related to the Montrose, Poplar Towers and Totem Valley properties. In order to
keep the properties competitive, building and tenant improvements will continue
to be required.
 
   The Partnership had cash of approximately $1,222,000 at June 30, 1997. PBP is
not being reimbursed for its general and administrative expenses (other than
printing) on a current basis; however, a payment for past due amounts of $50,000
was made in the second quarter of 1997. At June 30, 1997, the total liability
outstanding (including printing) was approximately $644,000. Cash on hand plus
any cash generated from operations may not be sufficient to fund building and
tenant improvements and to pay deferred general and administrative expenses.
 
   The General Partners of the Partnership believe that now is the appropriate
time to sell the Partnership's properties given current market conditions,
increased availability of investor capital, increased purchasing activity and a
favorable interest rate environment, among other reasons.
 
   The General Partners are preparing a proxy statement to be filed with the
Securities and Exchange Commission that will be sent to limited partners
requesting, among other things, their consent to sell the Partnership's
properties to Glenborough Realty Trust Incorporated, an affiliated 
entity of the Glenborough General Partner, at a price equal to the 
appraised value of the Partnership's properties. Such sale will be 
subject to certain conditions as will be more fully discussed in 
such proxy statement.

Results of Operations
 
   The Partnership's net loss decreased by approximately $33,000 and increased
by approximately $14,000 for the six and three months ended June 30, 1997 as
compared to the corresponding period in 1996 for the reasons discussed below.
 
   Property operating revenues increased by approximately $168,000 and $77,000
for the six and three months ended June 30, 1997 as compared to the
corresponding period in 1996 as increases in Montrose, Poplar Towers, Gateway
and Totem Valley more than offset the decrease at the Park Plaza property. The
increase in operating revenues was primarily the result of increased occupancies
at the properties
 
   Recovery of expenses decreased by approximately $28,000 for the six months
ended June 30, 1997 as compared to the corresponding period in 1996 primarily
due to lower tenant recoveries at the Montrose property as a result of new
tenant leases.
 
   Property operating expenses decreased by $101,000 and $60,000 for the six and
three months ended June 30, 1997 as compared to the corresponding period in 1996
primarily due to decreases in property taxes and general repairs and
maintenance.
 
   Depreciation and amortization increased by approximately $208,000 and
$136,000 for the six and three months ended June 30, 1997 as compared to the
corresponding period in 1996 primarily due to the amortization of loan fees
relating to the December 1996 mortgage refinancing.
