Item 7.  Financial Statements and Exhibits

(c)      Exhibits

Exhibit 99.2      Press Release Dated March 13, 2003.

Item 9. Regulation FD Disclosure.

Some of the statements made by RCN in this Form 8-K (and press release) are
forward-looking in nature. Actual results may differ materially from those
projected in forward-looking statements as a result of a number of factors.
RCN believes that the primary factors include, but are not limited to,
availability of financing, ability to obtain regulatory approvals, uncertainty
relating to economic conditions, ability to attract and retain qualified
management and other personnel, changes in government and regulatory policies,
pricing and availability of equipment, materials, inventory and programming,
our ability to meet the requirements in our franchise agreements, the number
of potential customers in a target market, the completion of acquisitions or
divestitures, acceptance of the Company's services, development and
implementation of business support systems for provisioning and billing, the
availability and success of strategic alliances or relationships, ability to
overcome significant operating losses, ability to reduce overhead costs,
ability to develop and penetrate existing and new markets, technological
developments and changes in the industry, changes in the competitive
environment in which RCN operates and ability to produce sufficient cash flow.
Additional information concerning these and other important factors can be
found in RCN's filings with the Securities and Exchange Commission. Statements
in these filings should be evaluated in light of these important factors.

These and other risk factors are set forth in more detail in the Company's
Form 10-K for 2001 which is filed with the Securities and Exchange Commission.

The information in this Current Report on Form 8-K is furnished pursuant to
Item 9 and shall not be deemed to be filed for the purposes of Section 18 of
the Securities Exchange Act of 1934 or otherwise subject to the liabilities of
that Section. The filing of this Current Report on Form 8-K is not an
admission as to the materiality of any information in this report that is
required to be disclosed solely by reason of Regulation FD.

The information contained in this Current Report on Form 8-K is summary
information that is intended to be considered in the context of our SEC
filings and other public announcements that we may make, by press release or
otherwise, from time to time. We undertake no duty or obligation to publicly
update or revise the information contained in this Current Report on Form 8-K,
although we may do so from time to time as we believe warranted. Any such
updating may be made through the filing of other reports or documents with the
SEC, through press releases or through other public disclosure.
