ITEM 2.           Acquisition or Disposition of Assets

         The  Registrant  acquired  a $62.6  million  mortgage  loan  obligation
(approximately  78% of which  has been  funded  to date).  The  Registrant  also
acquired a $25 million real estate  mezzanine loan. The Registrant also acquired
in separate  transactions two mortgage loan participation  interests aggregating
approximately $30 million.  The Registrant also acquired a $22 million preferred
equity interest in an enterprise that owns an operating property.
These transactions are discussed below.

         Cortlandt Street Mortgage Loan Acquisition

         On December 23, 1997,  the  Registrant  purchased  with existing cash a
$62.6 million  mortgage loan  obligation  (the  "Cortlandt  Mortgage Loan") from
Credit Suisse First Boston  Corporation  ("CSFB") at a premium of  approximately
102%.  The  Cortlandt  Mortgage  Loan  is  secured  by a  first  mortgage  on an
approximately  668,000  square  foot  office and retail  property  located at 22
Cortlandt Street in New York City (the "Cortlandt Property").


         With the  acquisition  of the Cortlandt  Mortgage  Loan, the Registrant
acquired an outstanding  loan of approximately  $48.6 million,  representing the
funded  portion  of the loan  obligation,  and  assumed  an  obligation  to make
additional  advances of  approximately  $14 million,  representing  the unfunded
portion  of  the  loan  obligation,   to  fund  reserves  for  interest,  tenant
improvements, and leasing commissions.

         The Cortlandt  Mortgage  Loan,  which  matures in January  2001,  bears
interest at a fixed spread over LIBOR for its term.  Prepayment of the Cortlandt
Mortgage Loan is permitted during the entire loan period. The Cortlandt Mortgage
Loan is subject to a prepayment  penalty  during the first two years of the loan
and carries no  prepayment  premium or penalty for the final year of the loan. A
specified fee is due from the borrower to the Registrant  upon the  satisfaction
of the Cortlandt Mortgage Loan.

         135 East 57th Street Mezzanine Loan Acquisition

         On December 29, 1997, the Registrant  purchased a $25 million mezzanine
loan  from  CSFB  (the  "135  East  57th  Mezzanine   Loan")  at  a  premium  of
approximately  103%.  The 135 East 57th Mezzanine Loan is secured by a pledge of
the  ownership  interests in the  entities  that own the  approximately  412,000
square  foot office and retail  property  located at 135 East 57th Street in New
York City (the  "East  57th  Property").  The 135 East  57th  Mezzanine  Loan is
additionally  secured by a full payment guaranty by the principals which own the
East 57th Property in the event of certain occurrences, including bankruptcy.

         The purchase price was funded with a combination of existing cash (25%)
and financing (75%) through a repurchase  obligation  ("REPO") with an affiliate
of CSFB which bears  interest at a specified  rate above  LIBOR.  The REPO has a
one-year term that may be extended by mutual agreement.  Simultaneously with the
purchase of the 135 East 57th Mezzanine  Loan,  the Registrant  entered into the
following  agreements:  (i) an interest rate swap  agreement (the "Swap") with a
commercial  bank  pursuant  to which it will  receive  interest  at LIBOR on the
notional   amount  of  the  Swap  in  exchange  for  fixed  rate   payments  for
approximately  the first six years of the 135 East 57th Mezzanine Loan, and (ii)
a forward  interest  rate cap  agreement  (the "Cap")  pursuant to which it will
receive payments should LIBOR exceed a specified threshold level on the notional
amount of the Cap for  approximately  the final  four years of the 135 East 57th
Mezzanine Loan.

         The 135 East 57th  Mezzanine  Loan,  which  matures in September  2007,
bears a fixed interest rate for the term of the loan. Prepayment of the 135 East
57th Mezzanine Loan is permitted  during the entire loan period subject to yield
maintenance  during  the  first  six  years of the loan and  without  prepayment
premium or penalty for the remainder of the loan term.









         1325 Avenue of the Americas Participation Interest Acquisition

         On December 30, 1997, the Registrant  acquired,  with existing cash, at
par from EOP Operating Limited Partnership  ("EOP")  approximately $20.1 million
of the  approximately  $25.1  million pari passu  interest (the  "Acquired  1325
Participation  Interest")  in the $50.3  million loan secured  principally  by a
second  mortgage on the  commercial  office tower  located at 1325 Avenue of the
Americas in New York City which contains  approximately 750,000 square feet (the
"1325  Mortgage  Loan").  Equity Office  Properties  Trust,  an affiliate of the
Registrant, is the general partner of EOP.

         The Registrant  previously originated and funded the 1325 Mortgage Loan
and simultaneously  sold the  above-mentioned  approximately  $25.1 million pari
passu  participation  interest to EOP. The foregoing  transactions were reported
under "Item 2.  Acquisition or Disposition of Assets" of the  Registrant's  Form
8-K Current  Report,  dated  November 7, 1997, as filed with the  Securities and
Exchange  Commission  on  November  14,  1997,  and the  information  set  forth
thereunder is incorporated herein by reference.

         As a result  of the  acquisition  of the  Acquired  1325  Participation
Interest,  the  Registrant's  share of the 1325 Mortgage  Loan is  approximately
$45.3 million.

         The Chicago Apparel Center Participation Interest Acquisition

         On December 31, 1997, the Registrant  acquired,  with existing cash, at
par from Bank of America  two-thirds  (or $10  million) of the $15 million  pari
passu  participation   interest  (the  "Acquired  Apparel  Center  Participation
Interest")  in  the  $35  million   short-term   second  mortgage  loan  secured
principally  by The Chicago  Apparel  Center  located in Chicago,  Illinois (the
"Apparel Center Mortgage  Loan").  With the acquisition of the Acquired  Apparel
Center  Participation  Interest,  the Registrant acquired an outstanding loan of
approximately  $6.6  million,  representing  the  funded  portion  of  the  loan
obligation allocated to the Acquired Apparel Center Participation  Interest, and
assumed an obligation to make additional advances of approximately $3.4 million,
representing  the  unfunded  portion  of the loan  obligation  allocated  to the
Acquired Apparel Center Participation Interest.

         The  Registrant  previously  originated  and funded in part the Apparel
Center  Mortgage Loan and thereafter sold the  above-mentioned  $15 million pari
passu participation interest to Bank of America. The foregoing transactions were
reported   under  "Item  2.   Acquisition  or  Disposition  of  Assets"  of  the
Registrant's Form 8-K/A Current Report,  dated August 4, 1997, as filed with the
Securities and Exchange  Commission on October 17, 1997 and the  information set
forth thereunder is incorporated herein by reference.

         As  a  result  of  the  acquisition  of  the  Acquired  Apparel  Center
Participation  Interest,  the maximum amount of the Apparel Center Mortgage Loan
obligation  allocated to the Registrant is $30 million,  of which  approximately
$20 million has been funded to date.

         MGM Preferred Equity Interest Acquisition Transaction

         On December 31, 1997, the Registrant  acquired a $22 million  preferred
equity interest from CSFB (the "MGM Plaza Preferred Equity  Interest").  The MGM
Plaza  Preferred  Equity Interest  represents a portion of the preferred  equity
interest  in the  limited  liability  company  that owns the  approximately  1.1
million  square foot office and retail  property known as the MGM Plaza which is
located at 2501  Colorado  Avenue in Santa  Monica,  California  (the "MGM Plaza
Property").

         The purchase was funded with a  combination  of existing cash (25%) and
financing  (75%)  through a  repurchase  obligation  with an  affiliate  of CSFB
bearing  interest at a specified rate above LIBOR.  The REPO has a one year term
that may be extended every three months by mutual agreement.








         The MGM Plaza  Preferred  Equity  Interest  has a remaining  term of 34
months and pays dividends at a specified rate over LIBOR until redemption. Early
redemption of the Preferred  Equity  Interest is not permitted  during the first
four  months  following  closing  of the MGM  Plaza  Preferred  Equity  Interest
acquisition transaction  ("Acquisition Closing"). The MGM Plaza Preferred Equity
Interest is subject to early redemption  penalties for the period from the fifth
through the 22nd months following  Acquisition Closing and is not subject to any
penalties during the last year preceding the mandatory redemption date.
