                              THE ANNUAL MEETING

Place, Date and Time

  The Annual Meeting will be held at The Princeton Marriott in Forrestal
Village, 201 Village Boulevard, Princeton, New Jersey 08540, on Tuesday, May
16, 2000, at 11:00 A.M., local time.

Purpose of the Annual Meeting

  Shareholders of the Company will consider and vote upon the following
proposals: (i) to elect five (5) Class III Directors to serve for a term of
three (3) years; (ii) to ratify the appointment of PricewaterhouseCoopers LLP
as independent auditors of the Company for the fiscal year ending December 31,
2000; (iii) to adopt the Company's 2000 Employee Stock Purchase Plan; and (iv)
to approve amendments to the Company's 1997 Equity Incentive Plan.

Record Date, Quorum, and Required Vote

  The close of business on March 24, 2000, has been fixed as the record date
for the determination of shareholders entitled to notice of and to vote at the
Annual Meeting and at any adjournment or postponement thereof. On March 24,
2000, there were 81,139,956 outstanding shares of Common Stock, 1,660,267
shares of Series B 7% Senior Convertible Preferred Stock ("Preferred Stock")
and no other equity voting securities of the Company. The shares of Preferred
Stock, currently held by one shareholder, are convertible into an aggregate of
26,778,500 shares of Common Stock, except to the extent that the number of
shares to be issued upon conversion would entitle the holder to cast more than
15% of the aggregate votes that all shareholders are entitled to cast (or a
greater percentage under certain circumstances), in which event the excess
will be issued as shares of non-voting Class B Common Stock. The Preferred
Stock is entitled to be voted on an as converted basis, and the holder of the
Preferred Stock has agreed to vote its shares (i) with respect to the election
of members of the Board of Directors of the Company, for nominees who have
been recommended by the Board of Directors and (ii) with respect to all other
matters (and subject to exceptions in the case of proposals to approve a
change of control transaction or to approve a stock issuance), either pro rata
with the voting of other shareholders or as recommended by the Board of
Directors of the Company to shareholders generally, at the election of the
holder. See "Transactions with Related Parties."

  The presence at the Annual Meeting, in person or by proxy, of shareholders
entitled to cast a majority of the votes entitled to be cast at the Annual
Meeting shall constitute a quorum at the Annual Meeting. Shareholders will be
entitled to one vote per share of common stock on all matters to be submitted
to a vote at the Annual Meeting. Shareholders do not have cumulative voting
rights with respect to the election of Directors.

  In accordance with Delaware law, a shareholder entitled to vote for the
election of Directors can withhold authority to vote for all nominees for
Directors or can withhold authority to vote for certain nominees for
Directors.

  Directors will be elected by a plurality of the votes cast at the Annual
Meeting. The approval of Proposal 2 (regarding the appointment of
PricewaterhouseCoopers LLP), Proposal 3 (regarding the 2000 Employee Stock
Purchase Plan), and Proposal 4 (regarding the 1997 Equity Incentive Plan)
requires the affirmative vote of a majority of the shares of Common Stock and
Preferred Stock present in person or by proxy and entitled to vote at the
Annual Meeting. Abstentions, votes withheld and broker non-votes (described
below) are counted in determining whether a quorum is present. Abstentions
with respect to any proposal other than the election of Directors will have
the same effect as votes against the proposal, because approval requires a
vote in favor of the proposal by a specified majority. Broker non-votes occur
when a broker or other nominee holding shares for a beneficial owner does not
receive voting instructions from the beneficial owner. Broker non-votes will
have no effect on the outcome of any of the proposals to be considered at the
Annual Meeting.

                                  PROPOSAL 1

                             ELECTION OF DIRECTORS

  The Company's Board of Directors is divided into three (3) classes and is
currently comprised of fifteen (15) members. One (1) class is elected each
year for a three-year term. Class III Directors whose term will expire at the
Annual Meeting include the following nominees, all of whom are presently
Directors of the Company: David C. McCourt, James Q. Crowe, Eugene Roth,
William D. Savoy and Walter Scott, Jr. These five (5) nominees, if elected at
the 2000 Annual Meeting, will serve for a term of three (3) years expiring at
the Annual Meeting of Shareholders to be held in 2003.

  It is not anticipated that any of the above nominees will become unavailable
for any reason, but, if any of the nominees should become unavailable before
the Annual Meeting, the persons named on the enclosed Proxy reserve the right
to substitute another person of their choice as nominee in place of such
person or to vote for such lesser number of Directors as may be prescribed by
the Board of Directors.

  THE BOARD OF DIRECTORS RECOMMENDS SHAREHOLDERS VOTE "FOR" THE ELECTION OF
THESE FIVE (5) NOMINEES AS CLASS III DIRECTORS TO SERVE FOR A TERM OF THREE
(3) YEARS.

                             DIRECTOR INFORMATION

  Information concerning the nominees for re-election as Class III Directors

                                  PROPOSAL 3

          PROPOSED ADOPTION OF THE 2000 EMPLOYEE STOCK PURCHASE PLAN

  The Company is proposing to adopt a new Employee Stock Purchase Plan ("Stock
Purchase Plan"). The Stock Purchase Plan is intended to be qualified under
Internal Revenue Code Section 423. If a plan is qualified under Section 423,
our employees who participate in the plan will enjoy certain tax advantages,
as described below. In order for the plan to be qualified, our shareholders
must approve the plan.

  The Stock Purchase Plan would allow our employees to purchase Common Stock
at a discount, without being subject to tax until they sell the stock, and
without having to pay any brokerage commissions with respect to the purchases.
In addition, an employee is not permitted to purchase stock exceeding $25,000
in fair market value for each calendar year.

  The purpose of the Stock Purchase Plan is to encourage the purchase of
common stock by the Company's employees, to provide employees with a personal
stake in the Company, and to help retain employees and maintain
competitiveness in the external marketplace. In addition, the Board can
approve the participation of any subsidiaries. Currently, only employees of
the Company and its subsidiaries would participate in the Stock Purchase Plan.
The first offering period under the Stock Purchase Plan would commence on or
after July 1, 2000, as determined by its administrator.

  The Stock Purchase Plan provides employees with the right to purchase shares
of Common Stock through payroll deductions. A total of 1,000,000 shares of
Common Stock are available for purchase under the Stock Purchase Plan, subject
to adjustment in the number and price of shares available for purchase in the
event the outstanding shares of Common Stock are increased or decreased
through stock dividends, recapitalizations, stock splits, reorganizations or
similar changes.

  The Stock Purchase Plan is administered by the Board of Directors, which may
delegate responsibility for administration to a committee of the Board.
Subject to the terms of the Stock Purchase Plan, the Board or the committee
has authority to interpret the Stock Purchase Plan, prescribe, amend and
rescind rules and regulations relating to it and make all other determinations
deemed necessary or advisable in administering the Stock Purchase Plan.

  A full-time employee is eligible to participate in the Stock Purchase Plan
if he or she is employed on the first day of an offering period. A part-time
employee is eligible to participate in the Stock Purchase Plan if, as of the
last day of the month immediately preceding the effective date of an election
to purchase the Company's common stock under the Stock Purchase Plan, he or
she has been employed by the Company on a part-time basis for 24 consecutive
months, or a shorter period of time as determined by the Company. An employee
is considered to be a part-time employee if the employee is scheduled to work
at least 20 hours per week. If the Stock Purchase Plan was effective as of
March 31, 2000, approximately 3,950 employees, including our Chief Executive
Officer and the Company's other executive officers, were eligible to
participate in the Stock Purchase Plan.

  Any employee who, after purchasing Common Stock under the Stock Purchase
Plan, would own 5% or more of the total combined voting power or value of all
classes of our stock or any subsidiary corporation is not eligible to purchase
additional stock under the Stock Purchase Plan. Ownership of stock is
determined in accordance with the provisions of Section 424(d) of the Internal
Revenue Code. In addition, an employee is not permitted to purchase stock
exceeding $25,000 in fair market value for each calendar year.

  Stock will be available to be purchased during an offering period. The
offering period will be a period of time determined by the Board or committee,
and may be on a payroll period, bi-weekly, monthly, quarterly, semi-annual,
annual, bi-annual and/or other basis. Eligible employees may elect to
participate in the Stock Purchase Plan prior to the start of an offering
period. Shares of Common Stock will be deemed to have been

                                       9
<PAGE>

purchased on the last day of the offering period. The purchase price per share
may be from 85% to 100% of the lesser of:

  .  the fair market value per share of Common Stock on the first day of the
     offering period; or

  .  the fair market value per share of Common Stock on the last day of the
     offering period.

  If any of these dates is not a trading day, then the fair market value will
be determined on the next trading day after such date. The purchase price may
also be discounted by some lesser amount than determined above. The Board or
committee will determine, with respect to any offering period, the amount, if
any, by which the purchase price will be discounted, which will be between 0%
and 15%, as described above.

  An eligible employee who wishes to participate in the Stock Purchase Plan
must file an election form with the Board or committee at least fifteen (15)
days before the beginning of an offering period. Each participant will have
payroll deductions made from his or her compensation on each regular payday
during the time he or she is a participant in the Stock Purchase Plan. All
payroll deductions will be credited to the participant's account under the
Stock Purchase Plan. A participant who is on an approved leave of absence may
authorize continuing payroll deductions.

  If the total number of shares of Common Stock for which purchase rights are
exercised at the end of an offering period exceeds the maximum number of
shares of Common Stock available, the Board or committee will make a pro rata
allocation of shares available for delivery and distribution. The unapplied
account balances will be credited to participants' accounts for the next
succeeding offering or, at the participant's election, returned to the
participant, without interest, as soon as practicable following the end of the
offering period.

  A participant may discontinue his or her participation in the Stock Purchase
Plan at any time, but no other change can be made during an offering period. A
participant may change the amount of payroll deductions for subsequent
offerings by giving written notice of such change to the Board or committee on
or before the 15th day of the month immediately preceding the beginning of an
offering period.

  A participant may elect to withdraw all, but not less than all, of the
balance credited to the participant's account by providing a termination form
to the Board or the committee at any time before the end of the offering
period. All amounts credited to such participant's account shall be paid as
soon as practicable following receipt of the participant's termination form,
and no further payroll deductions will be made with respect to the
participant.

  If a participant's employment terminates for any reason other than death,
all amounts credited to such participant's account will be returned to the
participant. If a participant's employment terminates due to death or the
participant dies after termination of employment but before the participant's
account has been returned, all amounts credited to such participant's account
will be returned to the participant's successor-in-interest.

  All funds held or received by the Company under the Stock Purchase Plan may
be used for any corporate purpose until applied to the purchase of shares of
Common Stock or refunded to employees and shall not be required to be
segregated from the Company's general assets. Shares of the Common Stock
purchased under the Stock Purchase Plan will be issued from the Company's
authorized but unissued shares. The Company will pay all fees and expenses
incurred, excluding individual federal, state, local or other taxes, in
connection with the Stock Purchase Plan.

  An employee's rights under the Stock Purchase Plan belong to the employee
alone and may not be transferred or assigned to any other person during the
employee's lifetime. After the shares of Common Stock have been issued under
the Stock Purchase Plan, such shares may be assigned or transferred the same
as any other shares.

  The Stock Purchase Plan would not be qualified under Section 401 (a) of the
Internal Revenue Code. The Company generally will not be entitled to a
deduction with respect to stock purchased under the Stock Purchase Plan,
unless the stock is disposed of less than one (1) year after it is purchased
by the employee, or less than two (2) years after the start of the offering
period pursuant to which the stock was purchased.

  Generally, no tax consequences arise at the time an employee purchases
shares of Common Stock under the Stock Purchase Plan. In general, upon a
disposition of shares, the participant will receive compensation taxable as
ordinary income for the taxable year in which the disposition occurs in an
amount equal to the lesser of:

  .  the excess of the fair market over the purchase price value of the
     shares at the beginning of the offering period, or

  .  the excess over the purchase price of (a) the amount actually received
     for the shares if sold or exchanged or (b) the fair market value of the
     shares on the date of any other termination of his or her ownership
     (such as by gift).

  The amount of such ordinary income is then added to the participant's basis
in his shares for purposes of determining capital gain or loss. This tax
treatment only applies if the following holding period requirement is
satisfied:

  .  the participant does not dispose of the shares for at least one (1) year
     after the date of purchase, and

  .  the participant does not dispose of the shares for at least two (2)
     years after the beginning of the offering period pursuant to which the
     shares were purchased.

  If a participant disposes of shares of Common Stock purchased under the
Stock Purchase Plan before the holding period is satisfied, he or she will
receive compensation taxable as ordinary income in the amount of the
difference between the amount paid for the shares and the fair market value of
the shares at the time of purchase. If the shares are sold or exchanged, the
amount of such ordinary income is added to the participant's basis in his
shares for purposes of determining capital gain or loss.

  If a participant dies before disposing of the shares purchased under the
Stock Purchase Plan, he or she will be deemed to have realized compensation
income taxable as ordinary income in the taxable year closing with his or her
death in an amount equal to the lesser of:

  .  the excess of the fair market over the purchase price value of the
     shares at the beginning of the offering period, or

  .  the excess over the purchase price of the fair market value of the
     shares on the date of death.

  He or she is deemed not to have realized any capital gain or loss because of
death.

  The Board or the committee will have the right to amend, modify or terminate
the Stock Purchase Plan at any time without notice, provided that, upon any
termination, all shares or unapplied payroll deductions will be distributed to
participants, and provided further, that no amendment will affect the right of
a participant to receive his or her proportionate interest in the shares or
unapplied payroll deductions. Upon any amendment of the Stock Purchase Plan,
shareholder approval will be obtained if required by law.

THE BOARD OF DIRECTORS RECOMMENDS THAT YOU VOTE "FOR" APPROVAL OF OUR PROPOSED
EMPLOYEE STOCK PURCHASE PLAN AS DESCRIBED IN THIS PROPOSAL 3.

                                  PROPOSAL 4

                    APPROVAL OF AMENDMENTS TO THE COMPANY'S
                          1997 EQUITY INCENTIVE PLAN

  The Board believes that granting stock options, restricted stock,
outperformance options and other forms of equity compensation is an effective
method of attracting able persons to enter and remain in the employ of the
Company and its subsidiaries, and also serves to provide incentives and
strengthen the identity of interests between them and the Company. The Company
is proposing to adopt certain amendments to the 1997 Equity Incentive Plan
(the "Equity Incentive Plan" or the "Plan").

  The Current Plan. As in effect prior to March 31, 2000, a total of
13,040,100 shares of Common Stock were subject to award under the Plan. Awards
may be made to employees of and consultants to the Company or its subsidiaries
and Directors of the Company. The Equity Incentive Plan is administered by the
Compensation Committee of the Board. The Board may amend or terminate the Plan
at any time.

  Following is a general summary of the types of awards that may be made under
the Equity Incentive Plan:

    Non-Qualified Options. Under a non-qualified option, the optionee has the
  right to exercise the option after it vests and becomes exercisable in
  exchange for the payment to the Company of the option price established at
  the time the award is made. In general, for federal income tax purposes,
  the optionee recognizes ordinary compensation income at the time of
  exercise; on a subsequent sale of option stock, the optionee recognizes
  capital gain or loss, which is long-term if the optionee has held the
  option stock for more than one (1) year. The Company is entitled to a
  deduction for compensation expense at the time of exercise of the option in
  the same amount recognized by the optionee at that time.

    Incentive Stock Options. Under an incentive stock option, the optionee
  has the right to exercise the option after it vests and becomes exercisable
  in exchange for the payment to the Company of the option price established
  at the time the award is made, which, in most cases, must be at least 100%
  of the fair market value of the option stock at the time of grant. In
  general, for federal income tax purposes, if the optionee holds the option
  stock for more than two (2) years from the date of grant and more than one
  (1) year from the date of exercise, the optionee will recognize long-term
  gain on the sale or other disposition of option stock equal to the excess
  of the net sales proceeds over the option price. The Company is not
  entitled to a deduction on the qualifying exercise and sale of option stock
  granted under an incentive stock option.

    Stock Appreciation Rights. Under a stock appreciation right ("SAR"), the
  holder has the right to exercise the SAR after it vests and becomes
  exercisable and receive payment in cash or stock in an amount equal to the
  excess of the fair market value of a share of stock on the date of exercise
  over the fair market value of a share of stock on the date of grant. In
  general, for federal income tax purposes, the holder recognizes ordinary
  income at the time of exercise equal to the amount of the payment and the
  Company is entitled to a deduction for compensation expense in the same
  amount at that time.

    Restricted Stock. A grantee of restricted stock must forfeit the
  restricted stock if the grantee terminates employment before the vesting
  date or if any other conditions attached to vesting are not satisfied.
  After the vesting conditions lapse, the grantee may retain the stock. In
  general, for federal income tax purposes, the grantee recognizes ordinary
  income at the vesting date equal to the fair market value of the stock on
  that date and the Company is entitled to a deduction for compensation
  expense in the same amount at that time.

    Performance Shares. A grantee of performance shares is entitled to
  receive shares of stock upon the satisfaction of pre-established
  performance goals. For federal income tax purposes, the grantee recognizes
  ordinary income equal to the value of the shares on the payment date and
  the Company is entitled to a deduction for compensation expense in the same
  amount at the same time.

    Phantom Stock Units. A grantee of phantom stock is entitled to receive
  shares of stock (or cash, in the discretion of the Compensation Committee)
  upon the completion of vesting conditions established by

                                      12
<PAGE>

  the Compensation Committee, together with cash equal to the amount of
  accrued dividend equivalents (measured by the amount of dividends paid per
  share during the vesting period).

    Outperformance Options. A holder of an outperformance option is entitled
  to receive shares of stock (or cash, in the discretion of the Compensation
  Committee) based on the performance of Common Stock of the Company compared
  to the performance of a pre-established stock performance index. After an
  outperformance option vests, the holder may exercise the outperformance
  option and receive stock and/or cash having a value equal to a pre-
  established multiple (not to exceed eight [8]) of the excess, if any, of
  the per share fair market value of Common Stock of the Company at the date
  of exercise over the "Adjusted Price." In general, the Adjusted Price is
  equal to the fair market value of a share at the date of grant, as adjusted
  for increases (but not decreases) in the pre-established performance index.
  The number of shares that can be acquired by a holder on the exercise of an
  outperformance option cannot be less than zero or exceed eight (8) times
  the number of shares designated as the basis of the award at the time of
  grant.

  Since the adoption of the Plan on October 1, 1997, employees of the Company
have received awards under the Plan. The Compensation Committee has the
discretion to determine the vesting schedule of awards. In general, with the
exception of options that have been assumed by the Company pursuant to its
purchase of various companies, awards vest ratably over three (3) or five (5)
years. No single participant can receive awards for more than 2,000,000 shares
of Common Stock in any one year.

  The Plan Amendments. Under the first amendment the Company is proposing to
adopt and that will be voted on by the shareholders at the meeting, the number
of shares of Common Stock authorized for issuance will be increased by
20,000,000 shares under the Plan.

  Under the second amendment the Company is proposing to adopt, the number of
shares of Common Stock that may be subject to awards pursuant to the Plan for
any one participant in a year will be increased from 2,000,000 to 4,000,000.

  Under the third amendment the Company is proposing to adopt the Adjusted
Price for outperformance options would both increase and decrease with the
changes in the performance of the pre-established performance index.

  Section 162(m) of the Internal Revenue Code precludes a public corporation
such as RCN from taking a deduction for compensation paid in excess of
$1,000,000 per person to its Chief Executive Officer or any of its four (4)
other highest paid officers. Certain performance-based compensation, however,
is exempt from the deduction limitation. Performance-based compensation must
be determined by a committee comprised solely of two (2) or more outside
Directors. In order to qualify as an outside Director, a person may not be an
employee of the Company and generally may not receive, directly or indirectly,
compensation for services other than in that person's capacity as a Director.
Currently, the members of the Compensation Committee meet the preceding
criteria.

  In addition, in order to qualify as performance-based compensation, the Plan
under which the awards are granted must state the maximum number of shares
that any one participant may receive during a specified time period. This
individual limit must be disclosed to and approved by shareholders. If a plan
containing this individual limit is not approved by shareholders, and any
awards under the Plan result in the Chief Executive Officer or one of the four
(4) highest paid officers receiving compensation in excess of $1,000,000, then
the compensation in excess of $1,000,000 will not be deductible by the
Company. To that end, in order to achieve the favorable tax treatment the
Company desires, the Board will amend the Equity Incentive Plan to increase
the individual limit.

  On April 14, 2000, the last reported sales price of the Common Stock of RCN
as reported on Nasdaq was $40.44 per share.

THE BOARD OF DIRECTORS RECOMMENDS THAT YOU VOTE "FOR" APPROVAL OF THE
AMENDMENTS TO OUR EQUITY INCENTIVE PLAN AS DESCRIBED IN THIS PROPOSAL 4.

(1)  Includes Share Units (further defined below) relating to the Common Stock
     acquired by each such named participant in lieu of current compensation
     and the vested Share Units credited to the Executive Stock Purchase Plan
     ("ESPP") account of each such named participant, as of March 31, 2000,
     including matching Share Units scheduled to vest within 60 days
     thereafter: Mr. McCourt, 112,821 shares; Mr. Mahoney, 36,828 shares; Mr.
     Godfrey, 37,984 shares; Mr. Haverkate, none; Mr. Adams, 22,443 shares;
     Mr. Stoklosa, 784 shares; and Mr. Jones, 2,961 shares. Under the ESPP,
     participants who defer current compensation are credited with "Share
     Units" with a value equal to the amount of the deferred pretax
     compensation. The value of a Share Unit is based on the value of a share
     of Common Stock. The Company also credits each participant's matching
     account under the ESPP with 100% of the number of Share Units credited
     based on the participant's elective contributions. Share Units credited
     to participants' elective contribution accounts are fully and immediately
     vested. Share Units credited to participants' matching accounts generally
     vest on the third anniversary of the date they are credited, subject to
     continued employment. Share Units credited to

                                      14

     a participant's matching account become fully vested on a change in control
     of the Company or on the participant's death or disability while actively
     employed. If dividends are paid on Common Stock, a dividend equivalent is
     deemed paid with respect to Share Units and credited to participants'
     accounts in the form of additional Share Units. The Company has established
     a grantor trust to hold Common Stock corresponding to the number of Share
     Units credited to participants' accounts in the ESPP. Participants do not
     have the right to vote Share Units, provided that the Company may, but is
     not required to, make arrangements for participants to direct the trustee
     of the grantor trust as to how to vote a number of shares held by the
     grantor trust corresponding to the number of Share Units credited to the
     participants' matching account.

                         COMPENSATION COMMITTEE REPORT

  The compensation programs for the Company's executive officers are
administered by the Compensation Committee (the "Compensation Committee") of
the Company's Board of Directors. The Compensation Committee makes
recommendations and/or determinations with respect to all executive
compensation matters.

  The Compensation Committee submits the following report on compensation for
the Company's executive officers for the 1999 fiscal year:

Compensation Philosophy

  As an emerging telecommunications company in highly competitive markets, the
Company's compensation philosophy must provide a framework for flexibility,
with a core component of compensation being performance based, with
significant portions of pay at risk. To insure the competitiveness of the
Company's compensation program, the Company utilized an Executive Value Index
("EVI") which was developed in 1998. The EVI includes predictive compensation
models designed from comparisons to a combination of public and private
compensation survey data as well as specific data from the proxy statements of
publicly-traded companies. The Company continued to use the basic philosophy
of providing senior level base salaries below that of the Company's peer
group, a short-term (annual) incentive opportunity equal to that of the peer
group, and a long-term incentive opportunity significantly above that of the
Company's peer group. The peer group is a selected group of high-technology
telecommunications and Internet companies.

  The Chief Executive Officer, with the review and approval of the
Compensation Committee, determines senior level base salaries and makes
recommendations with respect to short-term incentive grants and stock option
grants as he deems appropriate and consistent with the EVI guidelines and the
compensation philosophy of the Company.

  To further align the interests of the Company's executives with that of
shareholders, the Company encourages executives to acquire and maintain an
equity stake in the Company. To assist executives in accumulating this equity
position on a pre-tax basis, the Company implemented the ESPP pursuant to
which an executive may purchase Company stock through deferral of earned and
otherwise payable compensation, which is matched by the Company.

Executive Officer Compensation

  The salaries paid to executive officers by the Company for 1999 were
targeted to be below that of executive officers of the Company's peer group
and were based upon the consideration of certain employment data, an
assessment of the Company's and the officers' performance during the prior
year and certain subjective criteria.

  The amount of cash bonuses paid to executive officers for 1999 pursuant to
the bonus plan, as adopted by the Company was determined through a combination
of factors including the attainment of certain corporate business unit and
individual objectives (financial and non-financial), the compensation
practices of the Company's peer group, results of corporate and business unit
financial performances and certain subjective criteria.

  Stock options were granted to the executive officers named in the "Summary
Compensation Table." The Compensation Committee believes that such stock
options assist in recruiting, incentivizing and retaining executive talent and
the creation of shareholder value in the long-term, since the full benefit of
the compensation package cannot be realized unless the price of the Company's
stock appreciates over a specified number of years and the executive continues
to perform services for the Company. The number of stock options granted to
each executive officer and/or mid-level management employee was based on the
individual's salary band, title and evaluation of each executive's individual
performance and contribution to the Company's performance as presented to the
Compensation Committee. Certain stock option awards which were granted in
February 1999 and approved by the Compensation Committee were quarterly awards
rather than annual awards, with a five (5) year option exercise period rather
than a ten (10) year option exercise period, with vesting of one-third of the
option shares granted in each of the initial three (3) years of the five (5)
year option term.

Chief Executive Officer Compensation

  Mr. McCourt was paid a base salary and bonus of $500,000 and $2,000,000,
respectively for services rendered in 1999. Mr. McCourt's compensation for
1999 was structured so that his base compensation was below the level paid to
persons holding similar positions at similarly situated companies. Mr.
McCourt's short-term incentive award for 1999, which was earned under the
short-term plan adopted by the Company, reflects the outstanding
accomplishments that took place in 1999, the attainment of certain strategic
corporate objectives, and achievement of certain corporate financial and non-
financial goals including the acquiring and integrating of numerous Internet
companies intended to increase shareholder value. Specifically, Mr. McCourt
was instrumental in securing a total of $3,600,000,000 of additional capital
for the Company through convertible preferred offerings including an
investment from Vulcan, a senior bank facility, an equity offering, and a
senior notes offering.

Compliance with Internal Revenue Code Section 162(m)

  Section 162(m) of the Internal Revenue Code of 1986, as amended (the "Code")
denies a deduction by an employer for certain compensation in excess of
$1,000,000 per year paid by a publicly traded corporation to the Chief
Executive Officer and the four (4) most highly compensated executive officers
other than the Chief Executive Officer, unless such compensation is awarded
pursuant to a qualified performance-based program. Subject to the needs of the
Company, the Company's compensation plans are generally intended to qualify
for such qualified performance-based exemption.

                       TRANSACTIONS WITH RELATED PARTIES

  David C. McCourt, Chairman, Chief Executive Officer and Director of the
Company, is a Director of C-SPAN. In 1999, the Company paid approximately
$172,000 to C-SPAN for programming services.

  The Company paid NSTAR Communications approximately $42,000,000 for network
construction and paid BECO approximately $452,000 for utility services. Thomas
J. May, a Director of the Company, is Chairman and Chief Executive Officer of
BECO, as well as NSTAR Communications, which is a party to the joint venture
with RCN Telecom Holding Company.

  On April 7, 1999, the Company announced that Hicks Muse through HM4 RCN
Partners L.P. purchased $250 million of a new issue of Series A 7% Senior
Convertible Preferred Stock ("Series A Preferred Stock") of the Company in a
private placement transaction. The Series A Preferred Stock will have an
annual dividend rate of 7% payable quarterly in cash or additional shares of
Series A Preferred Stock at the option of the Company and will have an initial
conversion price of $39.00 per share (which represents a 30% premium over the
average five-day closing price of the Common Stock as of March 18, 1999). The
Series A Preferred Stock is convertible into Common Stock at any time. The
issue has a final maturity of fifteen (15) years, but may be called by the
Company after four (4) years. In connection with the placement of Series A
Preferred Stock, the Company agreed to provide HM4 RCN Partners L.P. with the
right to appoint one (1) Director to the Company's Board of Directors so long
as HM4 RCN Partners L.P. owns at least 50% of its initial investment and to
provide HM4 RCN Partners L.P. with certain registration rights. Michael J.
Levitt has been appointed to the Company's Board of Directors in connection
with this agreement.

  The Company agreed to provide or cause to be provided certain specified
services (management services) to CTE for a transitional period pursuant to
the Distribution Agreement dated as of September 5, 1997. The transitional
services to be provided include the following: (i) accounting; (ii) payroll;
(iii) management supervision and Office of the Chairman; (iv) cash management;
(v) human resources and benefit plan administration; (vi) insurance
administration; (vii) legal; (viii) tax; (ix) internal audit; (x) investor and
public relations; and (xi) other miscellaneous administrative services. The
fee per year for these services was 3.5% of the first $175 million of revenue
of CTE and 1.75% of any additional revenue. The total fees for 1999 and 1998
were approximately $5,235,000 and $7,016,000, respectively. During 1999, the
majority of the transitional services were transferred to CTE from RCN and
therefore the fee was adjusted downward accordingly. The transitional services
remaining in 2000 include legal and Office of the Chairman. The fee for these
services in 2000 is estimated to be approximately $2,000,000.

  CTE provided to the Company financial data processing applications, lockbox
services, storage facilities, local area network and wide area network support
services, building maintenance and other miscellaneous administrative
services. These services are no longer provided by CTE to the Company.

  The Company's subsidiary, RCN Long Distance Company ("RCN LD"), entered into
an agreement with CTE whereby CTE and its subsidiaries purchased long-distance
service from RCN LD. In 1999, CTE incurred approximately $8,200,000 of
expenses associated with this long-distance resale agreement and related
customer service expenses. This agreement is the result of arm's length
negotiations and fees are paid to RCN LD based on usage. In addition, CTE paid
RCN LD $143,000 for network costs.

  The Company paid Commonwealth Telephone Company ("CT") and CTSI, Inc., a
subsidiary of CTE ("CTSI"), approximately $732,000 in access charges as a
result of the Company originating and terminating traffic on CT and CTSI's
networks. CT also received approximately $420,000 in long-distance switch
rental revenue from RCN LD. In addition, CT and CTSI received approximately
$1,000,000 for local services, telephone access, and vertical service revenue
from the Company.

  During 1999, CT leased certain facilities owned by the Company. CT paid rent
to the Company on said facilities totaling approximately $47,000.

                                      23
<PAGE>

  The Company paid CTE, doing business as Commonwealth Communications,
approximately $310,000 in 1999 for engineering design and consulting service
business.

  The Company paid Level 3 approximately $4,000,000 for network construction
and approximately $3,340,000 for circuit costs. Messrs. Crowe, Scott and Jaros
are Directors of Level 3. Mr. McCourt, Chairman, Chief Executive Officer and
Director of the Company is also a Director of Level 3.

  The Company paid First Union Corporation approximately $257,000 for
financial services. Mr. Roth, a Director of the Company, is a Director of the
Pennsylvania Regional Board of Directors of First Union National Bank.

  The Company paid Sordoni Skanska, Slattery Skanska and Skanska E & C
approximately $2,900,000 for network construction. Mr. Graham, who is the
President of Skanska USA, Inc., is a Director of the Company.

  The Company paid the Hanify & King law firm approximately $172,000 for legal
services. Terence P. McCourt, Esq., a partner in the firm, is a brother of
David C. McCourt, Chairman, Chief Executive Officer and Director of the
Company.

  The Company paid USA Networks, Inc. approximately $952,000 for programming
services. William D. Savoy is a Director of the Company and USA Networks, Inc.

  On October 4, 1999, the Company announced that Vulcan, the investment
organization of Paul Allen, had agreed to make a $1.65 billion investment in
the Company. The investment is in the form of mandatorily convertible
preferred stock (the "Preferred Stock"), which may be converted into Common
Stock, par value $1.00 per share, no later than seven (7) years after it is
issued. Vulcan agreed to purchase 1,650,000 shares of Preferred Stock. The
Preferred Stock has a liquidation preference of $1,000 per share and is
convertible into common stock at a price of $62 per share.

  If Vulcan were to convert its Preferred Stock into Common Stock immediately,
it would receive 26,778,500 shares of Common Stock, which, together with the
3,407,100 shares of Common Stock currently owned by Vulcan, would represent
approximately 27.4% of the outstanding common stock after such conversion and
assuming the conversion of the Company's currently outstanding Series A 7%
Preferred Stock. Vulcan is, however, generally limited to owning Common Stock
representing no more than 15% of the vote entitled to be cast by the Company's
shareholders; provided that, if a change of control transaction is proposed to
the shareholders for approval, the 15% limitation is increased to an amount
equal to the voting percentage of LTH, which owns 26,640,970 shares of Common
Stock. In order to accommodate the voting limitation, the Preferred Stock is
also convertible into the Company's Class B Common Stock, par value $1.00 per
share ("Class B Stock"), which is essentially identical to the Common Stock
except that it is not entitled to vote. Vulcan has agreed to vote the Common
Stock it holds (i) with respect to the election of members of the Board of
Directors of Company, for nominees who have been recommended by the Board of
Directors, and (ii) with respect to all other matters (and subject to
exception in the case of proposals to approve a change of control transaction
or to approve a stock issuance), either pro rata with other shareholders or as
recommended by the Board of Directors of the Company to shareholders
generally, at the election of Vulcan. The Preferred Stock is entitled to vote,
but will be voted pro rata with other shareholders with certain limited
exceptions. William D. Savoy and Edward S. Harris have been appointed to the
Company's Board of Directors in connection with Vulcan's investment in the
Company.

  Level 3, the Company's controlling shareholder, and/or its affiliates has a
substantial stock ownership in LTH and the Company. These companies share
mutual Director representation on their respective boards.

                                 OTHER MATTERS

  The Board of Directors does not know of any other matters that may come
before the meeting. However, if any other matters properly come before the
meeting, it is the intention of the persons named in the accompanying form of
proxy to vote the proxy in accordance with their judgment on such matters.

  A copy of the Company's 1999 Annual Report to Shareholders containing the
Consolidated Financial Statements of the Company, including the report thereon
dated March 8, 2000, of PricewaterhouseCoopers LLP, independent accountants,
accompanies this Proxy Statement.

  Upon the written request of any person who, on March 24, 2000, was a record
owner of Common Stock or who represents in good faith that he was on such date
a beneficial owner of such Common Stock entitled to vote at the Annual
Meeting, the Company will furnish, without charge, a copy of the Company's
2000 Annual Report on Form 10-K, including the financial statements, schedules
and exhibits, filed with the Securities and Exchange Commission ("SEC").
Written requests for the Annual Report should be directed to: Investor

Solicitation of Proxies

  The Company will bear the cost of solicitation of proxies. In addition to
the use of the mail, proxies may be solicited by officers, Directors and
regular employees of the Company, personally or by telephone, telecopy or
telegraph, and the Company may reimburse persons holding stock in their names
or those of their nominees for their expenses in forwarding soliciting
materials to their principals.

  It is important that proxies be returned promptly. Therefore, shareholders
are urged to promptly fill in, date, sign and return the enclosed proxy in the
enclosed envelope, to which no postage need be affixed if mailed in the United
States. This will not prevent you from voting in person at the meeting. It
will, however, help to assure a quorum and to avoid added proxy solicitation
costs. In the alternative, shareholders are urged to promptly vote their proxy
via the internet or by telephone. Check your card or other information
forwarded by your broker, bank or other holder of record to see which options
are available to you.

Shareholder Proposals

information required by the relevant provisions of the Company's Bylaws must
be delivered by the shareholder to the Secretary of the Company at its
principal executive offices not less than 60 nor more than 90 days before the
Annual Meeting and, in the case of a proposal, the proposal must be an
appropriate subject for shareholder action under applicable law. In the event
that the Company receives notice within the time frame set forth above of a
shareholder proposal to be presented at the 2001 Annual Meeting of
Shareholders and which is not intended to be included in the Company's proxy
materials, then, so long as the Company included in its proxy statement for
such Annual Meeting of Shareholders advice on the nature of the matter and how
the named proxyholders intend to vote the shares for which they have received
discretionary authority, such proxyholders may exercise discretionary
authority with respect to such proposal, except to the extent limited by the
SEC's rules governing shareholder proposals.

Plan to the contrary, no Employee shall be granted an option to participate in
the Plan if:

          (1)  Immediately after the grant, such Employee would be a Five

requirements of sections 3(a) and 3(b) of the Plan and whose participation is
not restricted under section 3(d) of the Plan shall become a Participant by
completing an Election Form and filing it with the Committee on or before the
15th day of month immediately preceding the Offering Commencement Date for the
first Offering to which such Election Form applies.  Payroll Deductions for a
Participant shall commence on the applicable Offering Commencement Date when his

the Plan Termination Date, unless sooner terminated by the Participant pursuant
to section 8 of the Plan.

4.   Shares Per Offering.
     -------------------

     The Plan shall be implemented by a series of Offerings that shall terminate
on the Plan Termination Date.  Offerings shall be made with respect to
Compensation payable for each Offering Period occurring on or after adoption of
the Plan by the Board and ending with the Plan Termination Date.  Shares
available for any Offering shall be the difference between the maximum number of
Shares that may be issued under the Plan, as determined pursuant to section
10(a) of the Plan, for all of the Offerings, less the actual number of Shares
<PAGE>

purchased by Participants pursuant to prior Offerings.  If the total number of
Shares for which options are exercised on any Offering Termination Date exceeds
the maximum number of Shares available, the Committee shall make a pro rata
allocation of Shares available for delivery and distribution in as nearly a
uniform manner as practicable, and as it shall determine to be fair and
equitable, and the unapplied Account balances shall be returned to Participants
as soon as practicable following the Offering Termination Date.


5.   Payroll Deductions.
     ------------------

     (a)  Amount of Payroll Deductions.  An Eligible Employee who wishes to
          ----------------------------
participate in the Plan shall file an Election Form with the Committee at least
15 days before the Offering Commencement Date for the first Offering for which
such Election Form is effective on which he or she may elect to have Payroll
Deductions of such amounts designated by the Committee on the Election Form from
time to time made from his or her Compensation on each regular payday during the
time he or she is a Participant in the Plan, provided that the rules established
by the Committee shall be consistent with section 423(b)(5) of the Code.

     (b)  Participants' Accounts.  All Payroll Deductions with respect to a
          ----------------------
Participant pursuant to section 5(a) of the Plan shall be credited to the
Participant's Account under the Plan.

     (c)  Changes in Payroll Deductions.  A Participant may discontinue his
          -----------------------------
participation in the Plan as provided in section 8(a) of the Plan, but no other
change can be made during an Offering, including, but not limited to, changes in
the amount of Payroll Deductions for such Offering.  A Participant may change
the amount of Payroll Deductions for subsequent Offerings by giving written
notice of such change to the Committee on or before the 15th day of the month
immediately preceding the Offering Commencement Date for the Offering for which
such change is effective.

     (d)  Leave of Absence.  A Participant who goes on an Approved Leave of
          ----------------
Absence before the Offering Termination Date after having filed an Election Form
with respect to such Offering may:

          (1)  Withdraw the balance credited to his or her Account pursuant to
section 8(b) of the Plan;

          (2)  Discontinue contributions to the Plan but remain a Participant in
the Plan through the Offering Termination Date;
<PAGE>

          (3)  Remain a Participant in the Plan during such Approved Leave of
Absence through the Offering Termination Date and continue the authorization for
the Participating Company to make Payroll Deductions for each payroll period out
of continuing payments to such Participant, if any.

6.   Granting of Options.
     -------------------

     On each Offering Termination Date, each Participant shall be deemed to have
been granted an option to purchase the number of whole Shares equal to the
quotient obtained by dividing the balance credited to the Participant's Account
as of the Offering Termination Date, by the Option Price.

7.   Exercise of Options.
     -------------------

     (a)  Automatic Exercise.  With respect to each Offering, a Participant's
          ------------------
