Item 4.   Purpose of Transaction.
------    ----------------------

LAF,  LPC,  LOF,  LMF and LMOF  ("Loeb")  hold the  shares of  Common  Stock for
investment purposes.

On June 24, 2007,  the Issuer,  RCN  Corporation  ("RCN") and Raven  Acquisition
Corporation,  a wholly owned  subsidiary of RCN ("Merger Sub"),  entered into an
Agreement  and Plan of Merger (the "Merger  Agreement").  Under the terms of the
Merger Agreement, Merger Sub will merge with and into the Issuer (the "Merger"),
with the  Issuer  continuing  after  the  Merger  as the  surviving  entity.  In
connection with the Merger Agreement, Loeb has entered into a Support Agreement,
dated as of June 24, 2007, with the Issuer (the "Support  Agreement").  Pursuant
to the terms of the Support  Agreement,  Loeb has agreed to vote in favor of the
Merger and against  the  following  transactions  or  proposals  (other than the
transactions  contemplated  by the  Merger  Agreement):  (a)  any  extraordinary
corporate  transaction,  such  as a  merger,  consolidation  or  other  business
combination  involving the Issuer; (b) any sale, lease or transfer of a material
amount  of the  assets of the  Issuer,  or a  reorganization,  recapitalization,
dissolution  or  liquidation  of the  Issuer;  (c) any change in the persons who
constitute  the board of directors of the Issuer that is not approved in advance
by at least a majority of the persons who were directors of the Issuer as of the
date of the Support  Agreement (or their  successors who were so approved);  (d)
any material change in the present capitalization of the Issuer or any amendment
of the Issuer's  certificate of incorporation or bylaws not otherwise  permitted
under the Merger  Agreement;  or (e) any other action or proposal  involving the
Issuer that is intended,  or would reasonably be expected,  to prevent,  impede,
interfere  with,   delay,   postpone,   or  adversely  affect  the  transactions
contemplated by the Merger Agreement.

Subsequent to the closing of the Merger,  Loeb intends to review its  investment
in the  Issuer  on a  continuing  basis  and  may  engage  in  discussions  with
management  and the Board of Directors of the Issuer  concerning  the  business,
operations  and  future  plans of the  Issuer.  Depending  on  various  factors,
including,  without  limitation,  the Issuer's financial position and investment
strategy,  the price levels of the Common Stock,  conditions  in the  securities
markets and general  economic  and industry  conditions,  Loeb may in the future
take such  actions  with  respect  to its  investment  in the Issuer as it deems
appropriate including, without limitation, seeking Board representation,  making
proposals to the Issuer  concerning  the  capitalization  and  operations of the
Issuer,  purchasing  additional Common Stock,  selling some or all of its Common
Stock,  engaging in short selling of or any hedging or similar  transaction with
