      Pursuant to an Agreement and Plan of Merger dated as of January 31, 2001
(the "Merger Agreement") by and among the Issuer, ML Acquisition Corp., a newly
formed Delaware subsidiary of the Issuer ("Merger Sub"), Swift
Telecommunications, Inc., a New York corporation ("STI-NY") and the


--------------------------------------------------------------------------------
CUSIP NO. 560311 10 2             SCHEDULE 13D                 Page 4 of 8 Pages
--------------------------------------------------------------------------------


Reporting Person as the sole shareholder of STI-NY, STI-NY merged with and into
Merger Sub, with Merger Sub continuing as the surviving corporation and as a
wholly-owned subsidiary of the Issuer (the "Merger"). Upon the Merger, Merger
Sub changed its name to Swift Telecommunications, Inc. The Reporting Person was
the sole shareholder of STI-NY immediately before the Merger. Upon the
consummation of the Merger, the Issuer issued 18,776,176 shares of Issuer Common
Stock to the Reporting Person in payment of a portion of the merger
consideration payable in exchange for the Reporting Person's shares of stock of
STI-NY.

Item 4. Purpose of Transaction.

      The shares of Issuer Common Stock were issued to the Reporting Person in
payment of a portion of the consideration payable pursuant to the Merger. Upon
the Merger, the Issuer paid to the Reporting Person, as the sole shareholder of
STI-NY, $835,294 in cash and issued an unsecured note for approximately $9.2
million and 18,776,176 shares of Issuer Common Stock as the purchase price for
the acquisition of STI-NY. The Issuer also reimbursed the Reporting Person, as
the sole shareholder of STI-NY, for a $1.5 million advance made to STI-NY, the
proceeds of which were used to fund the balance of the cash portion of the
purchase price for STI-NY's acquisition of EasyLink Services and certain other
obligations to AT&T. Pursuant to the Merger Agreement, the Issuer will also pay
additional consideration to the Reporting Person, as the sole shareholder of
STI-NY, equal to the amount of the net proceeds, after satisfaction of certain
liabilities of STI-NY and its subsidiaries, from the sale or liquidation of the
assets of one of STI-NY's subsidiaries. The $9.2 million note issued as part of
the Merger consideration will be payable in four equal semi-annual installments
over two years and may be prepaid in whole or in part at any time and from time
to time without payment of premium or penalty. The note will be non-interest
bearing unless the Issuer fails to make a required payment within 30 days after
the due date therefore. Thereafter, the note will bear interest at the rate of
10% per annum. The note also contains certain customary events of default.

      On January 31, 2001, STI-NY acquired the EasyLink Services business from
AT&T Corp. Upon the closing of the acquisition by STI-NY of the EasyLink
Services business, the Issuer advanced $14 million to STI-NY in the form of a
loan, the proceeds of which were used to fund part of the cash portion of the
purchase price to AT&T. Upon the closing of its acquisition of STI-NY on
February 23, 2001, the Issuer assumed a $35 million note issued by STI-NY to
AT&T. The $35 million note is secured by the assets of STI-NY, including the
EasyLink Services business, and by the 18,776,176 shares of Issuer Common Stock
held by the Reporting Person.

      As part of the transaction with STI-NY, the Issuer has also agreed to
acquire Telecom International, Inc. (which is an affiliate of STI-NY and
conducts business under the name "AlphaTel"). Upon consummation of the
acquisition of Alpha-Tel, the Reporting Person will be entitled to receive up to
approximately $76,500 in cash, a promissory note in the aggregate principal
amount of up to approximately $841,000 and up to approximately 1.74 million
shares of Issuer Common Stock as part of the consideration payable to the
shareholders of Alpha-Tel. The acquisition of Alpha-Tel is subject to execution
of definitive documentation, receipt of regulatory approvals and other customary
conditions.

      Additionally, upon the closing of the STI-NY acquisition, the Reporting
Person became a director of the Issuer, received the right to designate an
observer to the Board of Directors of the Issuer and also entered into an
employment agreement with the Issuer.

      Issuer Common Stock. The 18,776,176 shares excludes 1,735,882 shares of
      Issuer Common Stock potentially issuable upon consummation of the
      acquisition of AlphaTel by the Issuer. See Item 4 above. This additional
      transaction is subject to execution of definitive documentation, receipt
      of regulatory approvals and other customary conditions.

            (b) The Reporting Person has the sole power to vote or to direct the

      Common Stock to AT&T Corp. to secure a promissory note in the original
      principal amount of $35 million issued by the Issuer in favor of AT&T. See
      Item 4 above.

            (e) Not applicable.

Item 6. Contracts, Arrangements, Understandings or Relationships with Respect to
        Securities of the Issuer.

      Except for (i) the Merger Agreement, (ii) the Pledge Agreement dated
January 31, 2001 between the Reporting Person and AT&T (the "Pledge Agreement"),
(iii) the Letter Agreement dated January 31, 2001 between the Issuer and the

securities of the Issuer, including but not limited to transfer or voting of any
of the securities, finder's fees, joint ventures, loan or option arrangements,
puts or calls, guarantees of profits, division of profits or loss, or the giving
or withholding of proxies.

      The Issuer acquired STI-NY, and the Reporting Person acquired his interest
in the Issuer, pursuant to the Merger Agreement. Pursuant to the Merger
Agreement, the Reporting Person is entitled to resale registration rights with
respect to the shares of Issuer Common Stock issued to him in the Merger pari
passu with other senior executives of the Issuer and on the same terms and
conditions granted to such executives.

      Under the Pledge Agreement, the Reporting Person pledged all of his shares
of Issuer Common Stock received pursuant to the Merger to AT&T Corp. to secure
the promissory note in the original principal amount of $35 million.

      Upon consummation of the acquisition of Alpha-Tel by the Issuer pursuant
to the Alpha-Tel Agreement, the Reporting Person would be entitled to receive up
to approximately 1.74 million shares of additional Issuer Common Stock.
