Royal Ahold extends tender offer

Zaandam, The Netherlands, May 20, 1999 - Ahold Acquisition, Inc., a wholly-owned
subsidiary of Royal Ahold, is extending the tender offer for the Preferred Stock
of Supermarkets General Holdings Corporation ("SMGH") until 5:00 p.m., New York
City time, on Friday, September 3, 1999. The offer had been scheduled to expire
on Friday, May 21, 1999.

The offer has been made pursuant to an agreement under which Royal Ahold will
acquire all of the outstanding shares of the capital stock of SMG-II Holdings
Corporation ("SMG-II"). SMG-II controls the US supermarket company Pathmark
Stores Inc. Based upon information provided by Citibank N.A., as depositary for
the offer, as of the close of business on May 17, 1999, approximately 1.1
million shares (22.4%) of the outstanding Preferred Stock have been tendered and
not withdrawn. Completion of the tender offer is subject to a number of
conditions, including obtaining necessary regulatory approvals and at least 66
2/3% of the shares of Preferred Stock being tendered in the offer and not
withdrawn. (It is standard practice that the majority of shares will not be
tendered until the final two days of the offering period.)

Ahold Acquisition agreed to extend the tender offer in connection with a
Memorandum of Understanding that has been entered into on May 19th. The
Memorandum set forth an agreement in principle of all concerned parties to
settle a purported stockholder class action lawsuit on behalf of the holders of
the SMGH Preferred Stock that had been brought against SMGH, its directors, its
parent company SMG-II and Ahold Acquisition. The action relates to the pending
tender offer and the allocation of the total consideration to be paid in the
transaction among the equity owners of SMGH and SMG-II.

The proposed settlement is subject to a number of conditions, including the
approval of the settlement by the Court of Chancery of the State of Delaware. If
such approval becomes final, Ahold Acquisition has agreed to amend its tender
offer to increase the offer price for the SMGH Preferred Stock to $40.25 per
share, less any fees and expenses awarded to plaintiff's counsel by the court
(which could total $0.40 per share of SMGH Preferred Stock). In such event, the
total amount of merger consideration to be paid to the holders of the capital
stock of SMG-II will be reduced accordingly. As a result, the overall
consideration Ahold Acquisition will pay in connection with the Pathmark
acquisition will not increase.

The total price payable by Ahold Acquisition for all of the capital stock of
SMG-II and the preferred stock of SMGH is approximately USD 250 million.
Pursuant to the agreement, Royal Ahold will also indirectly assume all of the
indebtedness of Pathmark, amounting to approximately USD 1.5 billion.
