EXPLANATORY NOTE

         At the time the Registrant filed its Annual Report on Form 10-K for the
year ended December 31, 1998, the Registrant intended to incorporate by
reference to its Proxy Statement for its 1999 Annual Meeting of Stockholders the
information required by Items 10, 11, 12 and 13 of Part III of Form 10-K, as
permitted by General Instruction G of Form 10-K. However, since the Registrant
no longer expects to file with the Securities and Exchange Commission the
definitive Proxy Statement for its 1999 Annual Meeting of Stockholders within
the time frame General Instruction G permits for incorporation by reference, the
missing information is being provided by the filing of this amendment.

     of the close of business on December 31, 1998, less the exercise price of
     each such option.

             Long-Term Incentive Plans - Awards in Last Fiscal Year

         No awards were granted to the Named Executive Officers under the
Company's Long Term Incentive Plan ("LTIP") during the year ended December 31,
1998.

Compensation of Directors

         Each of the Company's directors who is not an employee of the Company
receives an annual fee of $20,000 for serving as a director, and each member of
the Board of Directors' Compensation Committee (the "Compensation Committee"),
Related Party Transaction Committee (the "RPT Committee") and Audit Committee
(the "Audit Committee") receives a fee of $600 for each committee meeting
attended. The Compensation Committee, the RPT Committee and the Audit Committee
are all comprised of Messrs. Aaronson, Jacobson and McMahon. All directors are
also entitled to be reimbursed for their reasonable out-of-pocket expenses in
connection with all meetings of the Board of Directors and committee meetings
attended.

         Under the Company's 1993 Nonemployee Director Stock Option Plan (the
"Director Plan"), each director who is not an employee of the Company is granted
options to purchase 2,500 shares of Common Stock on the director's first
election to the Board of Directors and, thereafter through December 28, 2003, is
granted options to purchase an additional 2,500 shares of Common Stock at the
time of each annual meeting of stockholders for his or her prior year of service
as a director. Generally, one-half of each such grant of 2,500 options becomes
exercisable on the first anniversary of the date of the grant and the other half
of such grant becomes exercisable on the second anniversary of the date of the
grant. The nonemployee directors were not granted any options during the year
ended December 31, 1998 because the Company did not hold an annual meeting of
stockholders during 1998.

         If the Stock Incentive Plan is approved by the Company's stockholders,

Employment Arrangements and Compensation Plans

         During 1998, the Company had employment agreements with each of Leonard
S. Mandor, Robert A. Mandor, Joseph P. Otto and Harvey Shore which were entered
into in March 1993, effective as of January 1, 1993, each of which had initial
three year terms and could have been terminated on 30 days written notice by
either the Company or the executive officer. Pursuant to such agreements,
Leonard S. Mandor served as the Company's Chief Executive Officer, Robert A.
Mandor served as the Company's President and Chief Financial Officer, Harvey
Shore served as Senior Vice President and Secretary of the Company and Joseph P.
Otto served as a Vice President of the Company. In April 1996, the Compensation
Committee recommended, and the Board of Directors approved, three year
extensions, effective as of January 1, 1996, to each such employment agreement.
All of the agreements terminated at midnight on December 31, 1998. Pursuant to
the agreements, each of the individual executive officers named above were
entitled to receive annually a base salary and a discretionary bonus. The
initial annual base salary of each executive officer was subject to annual
increases at the discretion of the Board of Directors. In addition, the
agreements provided for certain benefits, including health care and life
insurance. In March 1995, the agreements between the Company and each of Harvey
Shore and Joseph P. Otto were amended to provide for six months' base salary as
severance pay in the event of the termination of their respective employment
with the Company without cause (as defined in such agreements). The Compensation
Committee recommended, and the Board of Directors approved, increases in the
base salary of each of Leonard S. Mandor, Robert A. Mandor, Harvey Shore and
Joseph P. Otto for the fiscal years ended December 31, 1994, 1995, 1996, 1997
and 1998. In addition, effective August 1, 1997, Joseph P. Otto's base salary
was increased in connection with an increased work load and greater
responsibilities assumed by Mr. Otto in connection with the resignation of
another executive officer. For the year ended December 31, 1998, the base
salaries of the above named executive officers were as follows: Leonard S.
Mandor -- $425,427, Robert A. Mandor -- $364,655, Harvey Shore -- $151,264 and
Joseph P. Otto -- $183,750.

         In March 1993, the Company entered into separate severance agreements
(the "Severance Agreements") with each of Leonard S. Mandor, Robert A. Mandor,
Harvey Shore and Joseph P. Otto. The Severance Agreements, which were superceded
on January 1, 1999 by new employment agreements (as discussed below), provided
that if the applicable executive's employment was terminated by the Company
without "cause" or by the executive for "good reason" within three years of a
"change in control" of the Company, the Company would pay to the executive a
termination payment of up to three times the executive's annual salary plus
certain bonuses, would pay to the executive all accrued fringe benefits and
would continue to provide insurance coverage as in effect on the date of
termination. For purposes of the Severance Agreements, "cause" included certain
misconduct by the executive, conviction of the executive of certain felonies and
neglect of the executive's duties; "good reason" included a breach by the
Company of the executive's employment agreement or severance agreement, removal
of the executive from any positions without cause or a significant adverse
change in the executive's working conditions or status; and "change in control"
included certain acquisitions of voting securities giving a person 20% or more
of the combined voting power of the Company, certain changes in the composition
of the Company's Board of Directors, certain mergers, consolidations,
reorganizations or dispositions of assets or the liquidation or dissolution of
the Company.

         Effective as of January 1, 1999, the Company entered into new
employment agreements with each of Leonard S. Mandor, Robert A. Mandor, Harvey
Shore, Joseph P. Otto and Patrick S. Kirse. Such agreements have an initial
three year term which will be automatically extended for additional consecutive
one year periods unless written notice is given by either party to the other no
later than 60 days before the expiration of the term. Pursuant to such
agreements, Leonard S. Mandor will continue to serve as the Chief Executive
Officer of the Company, Robert A. Mandor will continue to serve as the President
and Chief Financial Officer of the Company, Harvey Shore will continue to serve
as Secretary and a Senior Vice President of the Company, Joseph P. Otto will
continue to serve as a Vice President of the Company and Patrick S. Kirse will
continue to serve as a Vice President of the Company. Under each such agreement,
the executive is provided an annual base salary which is subject to annual
adjustments at the discretion of the Board of Directors of the Company (or a
committee thereof), but which may not be reduced to less than the base salary of
such executive for the initial year of his agreement. Pursuant to their
respective agreement, the initial base salary of each of the executive officers
is as follows: Leonard S. Mandor -- $446,698, Robert A. Mandor -- $382,887,
Harvey Shore -- $158,826, Joseph P. Otto -- $192,938 and Patrick S. Kirse --
$105,000. Effective as of April 19, 1999, the employment agreements of Robert A.
Mandor and Harvey Shore were amended to increase each such executive's base
salary by $25,000 and $18,358.34, respectively, in connection with an increased
work load and greater responsibilities. In addition, pursuant to their
respective 


                                       6
<PAGE>


agreement, each executive officer may be given an annual bonus. Bonuses awarded
to Messrs. Shore, Otto and Kirse pursuant to each executive's agreement are
subject to the sole discretion of the Board of Directors of the Company and are
in addition to any bonuses awarded to them under the Management Incentive Plan
(the "Management Incentive Plan"), as adopted by the Compensation Committee of
the Company on May 24, 1994, and bonuses payable to Leonard S. Mandor and Robert
A. Mandor are to be paid in accordance with the guidelines set forth in the
Management Incentive Plan and/or as otherwise determined by the Board of
Directors of the Company in its discretion. The employment agreements also
provide each executive officer with certain benefits, including a term life
insurance policy generally providing for a benefit of no less than $200,000 and
eligibility to participate in all benefit plans established by the Company
(including, but not limited to, medical, bonus and stock option programs). If an
executive's employment is terminated by the Company without "cause" or in
connection with, or as a result of, a "change of control" within three years of
such "change in control," including the executive's voluntary termination of his
employment with the Company within 60 days of a "change in control" if there is
a material change in the executive's working condition or status, the Company
would be obligated to pay to the executive a termination payment of up to three
times the executive's annual salary, then in effect, plus certain bonuses, and
would be obligated to pay to the executive all fringe benefits accrued at the
time of termination. For purposes of the employment agreements, "cause" includes
certain misconduct by the executive, conviction of the executive of a felony and
neglect of the executive's duties and "change of control" includes certain
acquisitions of voting securities giving a person 20% or more of the combined
voting power of the Company, certain changes in the composition of the Company's
Board of Directors, certain mergers or other business combinations, cash tender
or exchange offers, dispositions of assets or the liquidation or dissolution of
the Company.

         In February 1994, the Compensation Committee recommended, and the Board
of Directors of the Company approved, the creation of (i) the Management
Incentive Plan under which annual bonuses may be awarded to the Company's
executive officers pursuant to a formula based on (a) the Company's adjusted
pre-tax net profit for each year compared to an adjusted pre-tax net profit
target that is established for that year by the Compensation Committee, (b) the
performance of the Common Stock and the Series A Preferred Stock for that year
and (c) for the Company's executive officers other than the two most senior
executive officers (Leonard S. Mandor and Robert A. Mandor) the achievement of
certain individual performance objectives that were established for that year by
the Compensation Committee and (ii) the LTIP providing for a cash bonus to each
of Leonard S. Mandor and Robert A. Mandor of 9% of the adjusted pre-tax net
profits of MAMI in 1994, 1995 and 1996, which was subsequently extended to cover
1997, 1998, 1999 and 2000. Based on the achievement of certain Company
performance objectives, the Compensation Committee recommended the award of, and
the Board of Directors approved and awarded to Leonard S. Mandor and Robert A.
Mandor, bonuses for 1998 of $191,442 and $164,095, respectively, under the
Management Incentive Plan. In addition, on January 6, 1998, each of Leonard S.
Mandor and Robert A. Mandor were paid $334,730, representing bonuses accrued to
them under the LTIP for 1997. In January 1999, pursuant to the Management
Incentive Plan, Harvey Shore, Joseph P. Otto and Patrick S. Kirse were paid
bonuses for 1998 of $45,379, $62,295 and $30,000, respectively.

Compensation Committee Interlocks And Insider Participation

         During the fiscal year ended December 31, 1998, the Compensation
Committee of the Board of Directors of the Company consisted of Messrs.
Aaronson, Jacobson and McMahon. Mr. Aaronson is a shareholder in the law firm of
Schantz, Schatzman, Aaronson & Perlman, P.A., which firm performed various legal
services for the Company during the year ended December 31, 1998. Mr. McMahon is
a partner in the independent certified public accounting firm of John McMahon &
Sons, which firm performed accounting, tax and other general business advisory
services for the Company and its subsidiaries during the year ended December 31,
1998 and which firm derives a substantial portion of its revenues from the
services it provides to the Company, its subsidiaries and affiliates. The
Company paid $32,500 to John McMahon & Sons for services provided to the Company
during the year ended December 31, 1998. Except as set forth above, there were
no interlocks or insider participants, as defined in Item 402 of Regulation S-K
promulgated under the proxy regulations of the Exchange Act, during the fiscal
year ended December 31, 1998.

ITEM 12. SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

         The following table sets forth certain information with respect to the
beneficial ownership of securities of the Company as of the close of business on
April 26, 1999 by (i) each person known by the Company to beneficially own more
than 5% of any class of the Company's voting securities, (ii) each director and
nominee for director of the Company, (iii) the Company's Chief Executive Officer
and each of the Company's four most highly compensated executive officers who
beneficially owns shares of Common Stock or Series A Preferred Stock and (iv)
all directors, nominees for director and executive officers of the Company as a
group. The information in the table reflects the current conversion ratio for
the Series A Preferred Stock (which is convertible at any time, for no
consideration, into Common Stock) of 0.91 shares of Series A Preferred Stock to
be surrendered for each share of Common Stock to be received upon conversion.
The information in the table also gives effect to the Company's cancellation, as
of the close of business on March 5, 1999, of 2,983,284 shares of Series A
Preferred Stock in connection with the settlement of the Winston Actions.

         Except as noted below, each person has sole voting and investment power
with respect to the shares beneficially owned by such person. The Common Stock
is the only voting security of the Company, except that holders of the Series A
Preferred Stock currently have the right to elect two of the Company's
directors. A person is deemed to beneficially own a security if he or she has or
shares the power to vote or dispose of the security or has the right to acquire
it within 60 days.

ITEM 13. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

         The Company, certain past and present members of its Board of Directors
and executive officers, and Concord were named as defendants in the Winston
Actions, which were commenced in 1996. On August 5, 1998, the counsel for the
named plaintiff in the Winston Actions and the counsel for the defendants
entered into a Stipulation and Agreement of Settlement (the "Settlement
Agreement") which memorialized the terms of a settlement (the "Settlement") of
the Winston Actions. On January 28, 1999, the Delaware Court approved the
Settlement which approval became final effective as of the close of business on
March 5, 1999. In connection with the Winston Actions, the Company retained
counsel for all of the defendants, including, without limitation, Leonard S.
Mandor, Robert A. Mandor, Harvey Jacobson, Gregory McMahon and Geoffrey Aaronson
(each of whom is a director and/or officer of the Company) and assumed
responsibility for the payment of all legal fees incurred by such persons in
connection with the Winston Actions and the Settlement.

         In December 1990, the Company entered into an executive management
agreement, as amended (the "Executive Management Agreement"), with Concord,
pursuant to which the Company provides management services and assists Concord
in the management of certain properties (the "Concord Properties") owned by
Concord and its affiliates, including limited partnerships controlled by Concord
or affiliates of Concord. Pursuant to the Executive Management Agreement, which
is renewable annually, the Company makes available to Concord certain personnel
of the Company to provide management services (the "Management Services") to
Concord in connection with which Concord is required to reimburse the Company
based upon the hourly wage rate of such personnel, and the Company provides
Concord with office space and general office services. The Management Services
include overseeing all financing, acquisitions, dispositions and operational
functions of the relevant Concord Properties. The operational functions of the
Management Services include procuring and maintaining insurance, leasing,
supervising and administering expansion and maintenance projects, and performing
all other necessary services for maintaining the Concord Properties involved.
Under the Executive Management Agreement, affiliates of Concord engaged in real
estate brokerage activities may receive brokerage or leasing commissions in
connection with the purchase, sale or leasing of properties by the Company. In
March 1995, the Executive Management Agreement was amended to reduce by 50% the
quarterly fee paid by Concord to the Company for Management Services to its
present fee of $12,500 and to reduce by 50% the amount reimbursed by Concord for
office space and general office services. This reduction was occasioned by a
significant decrease in the Management Services. Pursuant to the Executive
Management Agreement, Concord owes the Company $67,491 and $163,188 for expenses
incurred by the Company in 1998 and 1997, respectively. In addition, Concord
owes the Company $76,576 and $69,910 for various services provided by the
Company to Concord in 1998 and 1997, respectively, pursuant to the Executive
Management Agreement. Leonard S. Mandor and Robert A. Mandor are the only
shareholders, the only directors and the Chief Executive Officer and the
President and Chief Financial Officer, respectively, of Concord. Harvey Shore is
the Secretary and a Senior Vice President of Concord and Joseph P. Otto is a
Vice President of Concord. Leonard S. Mandor and Robert A. Mandor beneficially
own in the aggregate all of the outstanding common stock of Concord.

         Milestone Properties Management, Inc. ("MPMI"), one of the Company's
wholly owned subsidiaries, is a party to a property management agreement (the
"Property Management Agreement") with Concord under which MPMI manages certain
properties owned by Concord and its affiliates, including limited partnerships
controlled by Concord or affiliates of Concord. Pursuant to the Property
Management Agreement, MPMI received $40,437 in termination fees and incurred
$10,725 of accelerated amortization in connection with the termination of
management agreements for the year ended December 31, 1998, resulting from the
sale or foreclosure of properties owned by limited partnerships syndicated by
Concord. As of December 31, 1998, MPMI performed property management and leasing
services for seven of Concord's shopping centers pursuant to the Property
Management Agreement.

         The Company's obligations as master lessee under 23 leases on
commercial real estate properties are guaranteed by Concord. The Company has no
obligation to indemnify Concord with respect to such guarantees.

         See the section "Compensation Committee Interlocks And Insider
Participation" of this amendment for a discussion of certain other relationships
