Exhibit 99.2      Press Release Dated May 14, 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 2002 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.
