(1)  On December 18, 1997, Messrs. Gottlieb and Lebowitz exercised options
     acquiring 67,000 shares of Common Stock each.  The Company received cash of
     approximately $645,000 from each of Messrs. Gottlieb and Lebowitz as a
     result of these option exercises.  Other compensation includes taxable
     income to Messrs. Gottlieb and Lebowitz in the amount of $708,000 each
     based upon the difference between the exercise price of $9.625 per share
     and the closing price of $20.1875 per share on December 18, 1997.  During
     1997, the Company also paid $17,500 and $17,200 for life insurance premiums
     for the benefit of Messrs. Gottlieb and Lebowitz, respectively.

(2)  Such amounts were paid to Messrs. Gottlieb and Lebowitz partially to defray
     tax liabilities imposed on them as a result of the transfer by the Company
     of the property at 436 North Bedford Drive, Beverly Hills, California
     (which was contributed by Messrs. Gottlieb and Lebowitz to the Company in
     exchange for Units in 1993) to the lender in satisfaction of the loan on
     the property.

(3)  Messrs. Carroll, Rauch and Nagler joined the Company in May 1997, October
     1996 and March 1998, respectively.  On an annualized basis, Messrs.
     Carroll, Rauch and Nagler would have earned base salaries of $120,000 in
     1997, $96,000 in 1996 , and $120,000 in 1998, respectively.

Employment Agreements and Arrangements

     In December 1993, each of Daniel M. Gottlieb and Steven D. Lebowitz entered
into separate but identical employment agreements with the Company and the
Operating Partnership for a term of three years.  The agreements provide for
automatic renewal for succeeding terms of one year unless the Company or Messrs.
Gottlieb or Lebowitz give notice at least three months prior to expiration of
any term.  The employment agreements provide for automatic annual increases in
base compensation equal to 5% per annum; however, the Compensation Committee of
the Board of Directors may review the annual base compensation every twelve
months in light of various factors, and following each such review, the annual
base compensation may be increased above the 5% automatic increase.

     In addition, each of Messrs. Gottlieb and Lebowitz are entitled to receive
an annual bonus as determined by the Compensation Committee in an amount not to
exceed a maximum of 100% of annual base compensation.  Furthermore, each
agreement provides that Messrs. Gottlieb and Lebowitz are entitled: (i) to
participate in all medical, dental, life insurance, retirement, profit sharing,
stock incentive, disability and bonus plans of the Company which may be made
available to executives of the Company (only medical plans presently exist) and
(ii) to severance payments, under certain circumstances, equal to two times
their then-current annual compensation.

     The agreements require Messrs. Gottlieb and Lebowitz to devote
substantially all of their working time and best efforts to performance of their
duties for the Company and, during the term of their employment, prohibits them,
with certain exceptions, from directly or indirectly owning or operating or
otherwise investing or participating in any other business that is in
competition with the business of the Company without the prior approval of a
majority of the independent members of the Board of Directors of the Company.

Compensation of Directors

     The Company pays an annual fee of $12,000 plus a fee of $1,000 for
attending regular meetings and $500 for attending committee meetings to its
directors who are not employees of the Company.  Employees of the Company who
are also directors are not paid any director fees.  Messrs. Gottlieb and
Lebowitz are the only directors who are also employees of the Company.  The
reasonable expenses incurred by each director in connection with the performance
of the director's duties are also reimbursed by the Company.  In addition,
pursuant to the 1993 Stock Incentive Plan, each nonemployee director is
automatically granted an option to purchase 500 shares of Common Stock each year
on the first business day after the date of the Annual Meeting and each person
who becomes a nonemployee director is granted an option to purchase 3,000 shares
of Common Stock upon joining the Board of Directors.  The exercise price of
these option grants is equal to 100% of the fair market value of the Common
Stock at the date of grant.

     On June 5, 1998, Messrs. Lesher, Michelson, Milner, Reilly and Tompkins
were each granted an option to purchase 500 shares of Common Stock at a price of
$17.50 per share.  These options became fully exercisable on December 5, 1998.
The options generally expire on the earlier of the first anniversary of the date
upon which the director shall cease to be a director as a result of death or
total disability, the 90th day after the date upon which the director shall
cease to be a director for any other reason or ten years after the date of
grant.

ITEM 13.  CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS


     The Company has adopted a policy pursuant to which material transactions
between the Company and its executive officers, directors and principal
Stockholders (i.e., Stockholders owning beneficially 5% or more of the
outstanding voting securities of the Company) are submitted to the Board of
Directors for approval by a disinterested majority of the directors voting with
respect to the transaction. For this purpose, a transaction is deemed material
if such transaction, alone or together with a series of similar transactions
during the same fiscal year, involves an amount which exceeds $60,000.

     In December 31, 1998, the Company acquired an office and retail complex
located in Coronado, California from a limited liability company (the "LLC")
owned by Messrs. Gottlieb and Lebowitz, each of whom is both a director and an
officer of the Company.  Messrs. Gottlieb and Lebowitz held interests in the LLC
of 30% and 70%, respectively.  The property was acquired for an aggregate
purchase price of $9.5 million.  The Company assumed $7.5 million in long-term
debt and issued 134,499 Units valued at $2.0 million.  The Units were issued at
an effective price of $14.87 per Unit, a 15.5% premium over the $12.875 closing
price of the Company's Common Stock on December 31, 1998.  In connection with
the purchase of the property, G&L Coronado Managers Corp., an entity owned 30%
and 70% by Messrs. Gottlieb and Lebowitz, respectively, signed a lease with the
Company for the entire third floor of the building.  Under the terms of the
lease, G&L Coronado Managers Corp. will lease the executive suites located on
the third floor of the building on behalf of the Company for rental payments
equal to $19,000 per month.  The lease expires on November 30, 2010.

     During 1998, a subsidiary of PHP Healthcare, Inc. ("PHP") occupied 100% of
six medical office buildings in New Jersey owned by the Company, which accounted
for approximately 10.8% of the Company's total rental revenues.  The Company
also purchased $2.8 million of PHP bonds for approximately $1.3 million during
1998.  In late November 1998, both PHP and its subsidiary filed for bankruptcy.
As a result, the Company has increased its reserves for delinquent rents and
established a reserve against the bonds.  Mr. Reilly, one of the Company's
directors, is the Chairman of the Board of Directors of PHP.

     On April 15, 1999, the Company borrowed $2.0 million from Reese L. Milner,
a director of the Company.  The loan bears interest at 12% per annum and is due
on May 13, 1999.  The Company also paid a loan fee of $20,000 to Mr. Milner.
The loan is secured by a first trust deed against a parcel of real property
owned by the Company.
