(1) Based upon the assumed number of shares that may be issued in the merger
    described herein. Such assumed number is based upon the maximum number of
    shares of Class A common stock and Class B common stock of Century
    Communication Corp. (including shares issuable upon exercise of
    outstanding options) that are expected to be outstanding immediately prior
    to the merger.
(2) These figures are estimates made solely for the purposes of calculating
    the registration fee pursuant to Rule 457 under the Securities Act of
    1933. The registration fee has been calculated in accordance with Sections
    (f)(1), (f)(2) and (f)(3) of Rule 457 based upon the market value of the
    securities which are publicly traded and the book value of the securities
    which are not publicly traded to be canceled in the merger, less
    $826,000,000, the approximate aggregate amount of cash to be paid by the
    Registrant in the merger. On August 6, 1999, there were 35,541,708 shares
    of Century Class A common stock outstanding (including shares issuable
    upon exercise of outstanding options) and the average high and low sale
    prices of such stock on The Nasdaq National Market System was $41.53, and
    there were 42,322,059 shares of Century Class B common stock outstanding
    with a book value per share of $1.00, resulting in an aggregate value of
    $1,518,369,192.
(3) Pursuant to Rule 0-11(a)(2) under the Securities Exchange Act of 1934, and
    Rule 457(b) of the Securities Act, the total registration fee of $192,479
    was reduced by $311,759.90, the filing fee paid by Adelphia pursuant to
    Exchange Act Rule 0-11 in connection with the filing of the preliminary
    proxy materials with the Securities and Exchange Commission on July 13,
    1999.

  The Registrant hereby amends this Registration Statement on such date or
dates as may be necessary to delay its effective date until the Registrant
shall file a further amendment which specifically states that this
Registration Statement shall thereafter become effective in accordance with
Section 8(a) of the Securities Act of 1933 or until the Registration Statement
shall become effective on such date as the Commission, acting pursuant to said
Section 8(a), may determine.

                                          August 12, 1999

   Dear Fellow Stockholders:

     As you probably know, our Boards of Directors have agreed to merge Century
with Adelphia.

     In the merger, stockholders of Century will receive Adelphia Class A
common stock and/or cash in exchange for their Century shares. Adelphia
stockholders will continue to own their shares of Adelphia. Adelphia Class A
common stock is quoted on the Nasdaq National Market under the symbol "ADLAC."

     Before we can go ahead with this merger, the stockholders of Adelphia and
Century must vote on proposals that will allow the merger to take place. These
proposals are described in the attached joint proxy statement/prospectus.

     The Boards of Directors of Adelphia and Century have each determined that
the merger is in the best interests of its stockholders. Each board unanimously
recommends that its stockholders vote FOR the proposal explained in the
enclosed joint proxy statement/prospectus.

     You should also carefully consider the risk factors relating to the
merger, Adelphia and Century that are described starting on page 18 of this
joint proxy statement/prospectus.

     By merging, we are combining two strong companies that should be in a
better position to compete in the telecommunications industry today and in the
future. We are excited about the opportunities for our customers, stockholders
and employees that should be available as a result of this merger. We believe
this merger will enhance Adelphia's long-standing position as a leader in the
cable television industry by merging Adelphia with another industry leader. We
also believe this merger will offer opportunities to expand our combined
business in exciting new ways. As a result, we urge you to join us in voting
FOR the merger.

Sincerely,                              Sincerely,

/s/ John J. Rigas

 commission has approved or disapproved of the shares of Adelphia Class A
 common stock to be issued in the merger, or passed upon the adequacy or
 accuracy of this joint proxy statement/prospectus. Any representation to the

      transaction is more fully described in the joint proxy

  Adelphia has filed a registration statement with the Securities and Exchange

of Adelphia. This document also constitutes the prospectus of Adelphia filed as
part of that registration statement.
<PAGE>

                     QUESTIONS AND ANSWERS ABOUT THE MERGER

Q:  What is the proposed transaction?

A:  Adelphia will acquire Century by merging Century into a subsidiary of
    Adelphia.

Q:  What will Century stockholders receive in the merger?

A:  It depends. For each share of Century Class A common stock you own, you may
    request to receive in the merger either: (1) 0.77269147 of a share of
    Adelphia Class A common stock, or (2) $44.14 in cash. For each share of
    Century Class B common stock you own, you may request to receive in the
    merger either: (1) 0.84271335 of a share of Adelphia Class A common stock,
    or (2) $48.14 in cash. Our ability to satisfy your request to receive the
    merger consideration you elect will be determined by how many Century
    stockholders request shares of Adelphia Class A common stock versus how
    many request cash. The merger agreement provides that no more than 79.24%
    of the outstanding shares of Century Class A common stock may be exchanged
    for shares of Adelphia Class A common stock and that no more than 20.76%
    may be exchanged for cash, excluding in each case shares held by dissenting
    stockholders. The merger agreement also provides that no more than 75.46%
    of the outstanding shares of Century Class B common stock may be exchanged
    for shares of Adelphia Class A common stock and that no more than 24.54%
    may be exchanged for cash, excluding shares held by dissenting
    stockholders. See "What Value You Will Receive In The Merger" on page iv
    and "The Merger Agreement And Related Agreements--The Merger Agreement--
    Election; Conversion of Century Shares; Proration, on pages 71-72." If we
    are unable to grant your exact request, you will receive a combination of
    shares of Adelphia Class A common stock and cash for your Century common
    stock.

Q: How do I elect the form of payment that I prefer?

A:  To elect the form of payment you prefer, you must complete a green form of
    election and letter of transmittal if you are a holder of Century Class A
    common stock or a blue form of election and letter of transmittal if you
    are a holder of Century Class B common stock, with instructions for making
    an election as to your preference between receiving Adelphia Class A common
    stock or cash in the merger. A form of election, together with a return
    envelope, is being mailed to you separately at the same time as the mailing
    of this joint proxy statement/prospectus. The fully completed form of
    election, together with your certificates representing outstanding Century
    Class A or Century Class B common stock, must be returned to American Stock
    Transfer & Trust Company before the election deadline on September 30,
    1999. If we do not expect to complete the merger within three to five
    business days after the special meetings, we will extend the election
    deadline and publicly announce the extension.

Q:  What happens if I don't make an election for cash or shares?

A:  If you fail to make an election prior to the election deadline, other than
    because you are exercising your appraisal rights, you will be deemed to
    have elected to receive Adelphia Class A common stock in the merger. The
    actual merger consideration that will be paid to you will depend upon how
    many Century stockholders request shares of Adelphia Class A common stock
    versus how many request cash.

Q:  Can the value of the transaction change between now and the time the merger
    is completed?

A:  Yes. The value of the Adelphia Class A common stock can change, although
    the $44.14 and $48.14 per share cash amounts will not change. The
    0.77269147 and 0.84271335 exchange ratios are fixed exchange ratios, which
    means that they will not change even if the trading price of Adelphia Class
    A common stock changes. Therefore, the market value of the total
    transaction, and of the Adelphia Class A common stock you may receive in
    the merger, will increase or decrease as the trading price of Adelphia
    Class A common stock increases or decreases.

Q: What are my tax consequences as a result of the merger?

A:  Your tax consequences will depend upon whether you receive Adelphia Class A
    common stock, cash, or a combination of Adelphia Class A common stock and
    cash, in the merger, and may also depend upon your basis in your Century
    stock. We have structured the merger so that our legal counsel will be able
    to deliver opinions that:

                                       i
<PAGE>

  .  neither Adelphia nor Century should recognize any gain as a result of the
     merger, and

  .  Century stockholders should not recognize any gain or loss for U.S.
     federal income tax purposes to the extent that they receive Adelphia
     Class A common stock in the merger.

  Century stockholders receiving both Adelphia Class A common stock and cash
  in the merger should recognize gain equal to the lesser of the amount of
  gain realized and the amount of cash received. Century stockholders
  receiving only cash will generally recognize gain and, depending upon their
  particular circumstances, likely will be permitted to recognize loss, equal
  to the difference between the amount of cash received and the stockholders'
  basis in their Century common stock.

  Adelphia stockholders will not recognize any gain or loss with respect to
  their Adelphia stock as a result of the merger.

  We describe the material U.S. federal income tax consequences of the merger
  in more detail on page 62. The tax consequences of the merger to you will
  depend upon the facts of your own situation. Please consult your own tax
  advisor for a full understanding of the tax consequences of the merger to
  you.

Q:  What will happen to outstanding shares of Adelphia Class A common stock in
    the merger?

A:  Nothing. Each currently outstanding share of Adelphia Class A common stock
    will remain outstanding with no change. After the merger, shares of
    Adelphia Class A common stock will represent ownership of the combined
    assets and businesses of Adelphia and Century.

Q:  Are Century stockholders entitled to appraisal rights?

A:  Yes. Holders of Century common stock are entitled to appraisal rights in
    connection with the merger. We describe the procedures for exercising
    appraisal rights in this joint proxy statement/prospectus on page 67 and we
    attach the provisions of New Jersey law that govern appraisal rights as
    Appendix D.

Q:  What happens if I dissent from the merger and exercise my appraisal rights
    but then withdraw my demand for appraisal or fail to establish or perfect
    or otherwise lose my appraisal rights?

A:  At such time, each of your shares of Century Class A common stock will be
    converted into $9.16426528 in cash and 0.61222732 shares of Adelphia Class
    A common stock and each of your shares of Century Class B common stock will
    be converted into $11.81417001 in cash and 0.63595483 shares of Adelphia
    Class A common stock.

Q:  When do you expect to complete the merger?

A:  We will complete the merger subsequent to the special meetings, subject to
    the satisfaction of all other closing conditions. Because the merger is
    subject to governmental approvals, however, we cannot predict the exact
    timing.

Q:  How do I vote?

A:  Just mail your signed proxy card in the enclosed return envelope or, for
    Century stockholders who have the option of telephone voting, you may vote
    by telephone using the toll-free telephone number listed on the enclosed
    instructions. Please vote as soon as possible so that your shares may be
    voted at your stockholders' meeting. Any registered stockholder present at
    the special meeting may vote in person. If you plan on voting your shares
    at the special meeting and your shares are held by a bank, broker or other
    nominee, you must obtain a legal proxy from that bank, broker or other
    nominee, otherwise we will not be able to count your vote.

Q:  If my shares are held in "street name" by my broker, bank or other nominee
    will those institutions vote my shares for me?

A:  Your broker, bank or other nominee, cannot vote your shares without your
    instructions. You should instruct your broker, bank or other nominee to
    vote your shares, following the directions it provides.

                                       ii

Q:  If I submit my proxy card, but fail to direct my vote, will my shares be
    voted?

A:  Yes. If you submit a properly executed proxy card to your broker, bank or
    other nominee but fail to direct how the proxies are to vote your shares of
    common stock on the merger proposal, your shares of common stock will be
    voted to approve the merger.

Q:  Can I change my vote?

A:  Yes. Only your latest dated vote counts. If you wish to change your vote,
    simply send in a later dated, signed proxy card and your original vote will
    be revoked. If the telephone voting option is available to you, and you
    voted by telephone, you can change your vote by a later dated telephone
    vote or by a later dated, signed proxy card. Please remember, only your
    latest dated vote counts. You can also change your vote by attending your
    stockholders meeting and voting in person.

Q:  When will Century Class A common stock cease to trade on the Nasdaq
    National Market?

A:  Century Class A common stock will cease to trade on the Nasdaq National
    Market at the close of business on the day the merger is completed.
    Adelphia Class A common stock, which Century stockholders will receive in
    the merger, currently trades on the Nasdaq National Market and will

   This summary highlights selected information from this joint proxy
statement/prospectus, and may not contain all of the information that is
important to you. To better understand the merger, and for a more complete
description of the terms of the merger and related matters, you should read
this entire document carefully, as well as those additional documents to which
we refer you. See "Where You Can Find More Information" on page 103.

The Merger (See Page 41)

   The proposed transaction is a merger of Century with and into a wholly owned
Adelphia subsidiary. In the merger, Adelphia will issue approximately 48.7
million shares of its Class A common stock, and pay approximately $826 million
in cash. The Adelphia shares to be issued have a market value of approximately
$2.7 billion based on Adelphia's closing price of $56.00 per share on August
12, 1999. As a result of the merger, approximately $2.0 billion in Century debt
will become part of Adelphia's total indebtedness.

   Each holder of Century Class A common stock will have the right to elect, on
a share-by-share basis, to receive either $44.14 in cash or approximately 0.77
of a share of Adelphia Class A common stock for each share of Century Class A
common stock held. Each holder of Century Class B common stock will have the
right to elect, on a share-by-share basis, to receive either $48.14 in cash or
approximately 0.84 of a share of Adelphia Class A common stock for each share
of Century Class B common stock held. The elections described above are subject
to proration as described on pages 71-72.

The Companies--Adelphia And Century (See Page 38)

Adelphia Communications Corporation
Main at Water Street
Coudersport, Pennsylvania 16915
Tel: (814) 274-9830

   Adelphia is a leader in the telecommunications industry with cable
television and local telephone operations. Adelphia's operations consist of
providing telecommunications services primarily over Adelphia's networks, which
are commonly referred to as broadband networks because they can transmit large
quantities of voice, video and data by way of digital or analog signals.
Adelphia owned or managed cable television systems with broadband networks that
passed in front of 7,667,162 homes and served 4,970,403 basic subscribers as of
March 31, 1999, after giving effect to the merger and the other pending
acquisitions described in "Recent Developments." Through its subsidiary,
Hyperion Telecommunications, Inc., Adelphia owns and operates a super-regional
provider of integrated communications services in the eastern half of the
United States. Adelphia currently also owns a 50% voting interest in Olympus
Communications, L.P., which is a non-consolidated joint venture that operates a
large cable system in Florida. Adelphia expects to acquire the remaining equity
interests in Olympus that it currently does not own during the third calendar
quarter of 1999. John J. Rigas, the Chairman, President, Chief Executive
Officer and founder of Adelphia, has owned and operated cable television
systems since 1952.

Century Communications Corp.
50 Locust Avenue
New Canaan, Connecticut 06840
Tel: (203) 972-2000

   Century is engaged primarily in the ownership and operation of cable
television systems with significant concentrations of basic subscribers in
California, Colorado and Puerto Rico. In the fall of 1998, Century entered into
an agreement with Tele-Communications, Inc. ("TCI") to create an approximately
69.5%-owned joint venture which will operate cable television systems serving
approximately 772,000 basic subscribers in

                                       1
<PAGE>

the Los Angeles area. As of May 31, 1999, and giving effect to the TCI joint
venture as if it had been completed prior to that date, Century owned and
operated cable television systems in 25 states and Puerto Rico that passed in
front of approximately 2,924,000 homes and served approximately 1,610,000 basic
subscribers.

Adelphia's Reasons For The Merger (See Page 45)

   Adelphia believes that the merger is consistent with its growth strategy,
and that it presents a rare opportunity to acquire, in a single transaction,
sizable and attractive cable television systems. In particular, Adelphia
believes that Century is a strong strategic fit with Adelphia because it will
provide a strong footprint in additional key markets. In addition, Adelphia
believes that the merger will enable Adelphia to continue to implement its
clustering strategy commenced many years ago. The merger also will
significantly increase Adelphia's market capitalization which, Adelphia
believes, will make Adelphia common stock attractive to a new class of
investors. Also, Adelphia believes that its knowledge and familiarity with
Century will facilitate the integration of the companies.

Century's Reasons For The Merger (See Page 47)

   Century believes that the merger offers its stockholders an attractive
premium for their shares, while enabling them to participate in the future
growth potential of the combined businesses of Adelphia and Century. Century
believes that the combination of the business of Century with the business of
Adelphia will result in a company that is better equipped to compete in the
changing telecommunications marketplace than either company would be able to
alone.

Opinions of Financial Advisors (See Page 50)

 Adelphia

   Adelphia's financial advisor, Daniels & Associates, L.P. ("Daniels"), has
given a written opinion to Adelphia's board that, as of March 5, 1999, the
merger consideration for the Century common stock, taken as a whole, was fair
to Adelphia and its common stockholders from a financial point of view. The
opinion is subject to the qualifications and limitations referred to in the
opinion. We attach a copy of the Daniels opinion as Appendix B, and we
encourage you to read it.

 Century

   In deciding to approve the proposed transactions, the Century board
considered the opinion of Donaldson, Lufkin & Jenrette Securities Corporation
("DLJ"), Century's financial advisor, that, as of the date of the opinion, the
merger consideration was fair, from a financial point of view, to the holders
of Century Class A common stock (other than stockholders who are affiliates of
Century). The opinion is subject to the qualifications and limitations referred
to in the opinion. We attach a copy of the DLJ opinion as Appendix C, and we
encourage you to read it.

The Merger Agreement (See Page 70)

 General

   We attach a copy of the merger agreement, as amended, which is the legal
document that governs the merger, as Appendix A, and we encourage you to read
this document. Adelphia has also filed other related agreements as exhibits to
Adelphia's registration statement. Please see the section titled "Where You Can
Find More Information," on page 103, for instructions on how to obtain a copy
of these exhibits.

 Structure of the Merger

   Subject to the terms and conditions of the merger agreement, Century will
merge with and into a wholly owned subsidiary of Adelphia. At the effective
time of the merger, the separate corporate existence of Century

                                       2
<PAGE>

will cease. Adelphia's subsidiary will be the surviving corporation in the
merger and will continue its corporate existence as a wholly owned subsidiary
of Adelphia. Adelphia's subsidiary is organized under the laws of the state of
Delaware.

 Consideration to be Received for Century Common Stock in the Merger

   The merger agreement provides that, at the effective time, each issued and
outstanding share of Century Class A common stock (other than shares held by
dissenting shareholders and shares held by Century) will, at the election of
each holder but subject to proration as described on pages 71-72, be converted
into the right to receive:

  .  0.77269147 of a share of Adelphia Class A common stock (the "Century
     Class A Per Share Stock Amount"); or

  .  $44.14 in cash (the "Century Class A Per Share Cash Amount"), or

  .  a combination of shares of Adelphia Class A common stock and cash;

and that each issued and outstanding share of Century Class B common stock
(other than shares held by dissenting stockholders and shares held by Century)
will, at the election of each holder but subject to proration as described on
pages 71-72, be converted into the right to receive:

  .  0.84271335 of a share of Adelphia Class A common stock (the "Century
     Class B Per Share Stock Amount"); or

  .  $48.14 in cash (the "Century Class B Per Share Cash Amount"), or

  .  a combination of shares of Adelphia Class A common stock and cash.

 Election; Conversion of Century Shares; Proration

   Each record holder or beneficial owner of Century common stock will be
entitled:

  .  to elect on a share-by-share basis to receive the Century Class A Per
     Share Cash Amount or the Century Class A Per Share Stock Amount for each
     such share of Century Class A common stock,

  .  to elect on a share-by-share basis to receive the Century Class B Per
     Share Cash Amount or the Century Class B Per Share Stock Amount for each
     such share of Century Class B common stock.

   Notwithstanding a Century stockholder's election, at the effective time of
the merger:

  .  the aggregate number of shares of Century Class A common stock that may
     be converted into the right to receive cash in the merger is equal to
     20.76% of the number of shares of Century Class A common stock
     outstanding immediately prior to the effective time (excluding shares
     held by dissenting stockholders),

  .  the aggregate number of shares of Century Class A common stock which may
     be converted into the right to receive shares of Adelphia Class A common
     stock in the merger is equal to 79.24% of the number of such shares of
     Century Class A common stock outstanding immediately prior to the
     effective time (excluding shares held by dissenting stockholders),

  .  the aggregate number of shares of Century Class B common stock that may
     be converted into the right to receive cash in the merger is equal to
     24.54% of the number of shares of Century Class B common stock
     outstanding immediately prior to the effective time (excluding shares
     held by dissenting stockholders) and

  .  the aggregate number of shares of Century Class B common stock which may
     be converted into the right to receive shares of Adelphia Class A common
     stock in the merger is equal to 75.46% of the number of such shares of
     Century Class B common stock outstanding immediately prior to the
     effective time (excluding shares held by dissenting stockholders).

                                       3
<PAGE>


   If the aggregate number of shares of Century Class A common stock or Century
Class B common stock with respect to which elections have been made exceeds the
aggregate number of shares of Century common stock of that class that may be
converted into the right to receive a particular form of consideration in the
merger, then

  .  each share of Century common stock electing to receive the
     undersubscribed consideration will receive that consideration; and

  .  each share of Century common stock electing to receive the
     oversubscribed consideration will receive a portion of the merger
     consideration in cash and a portion of the merger consideration in
     Adelphia Class A common stock.

   For a more complete description of the election process and proration
applicable to the merger, see "The Merger Agreement And Related Agreements--
Merger Agreement--Election; Conversion of Century Shares; Proration" on page
71.

 Election Procedure; Exchange of Certificates

   Forms of election are being sent contemporaneously to holders of Century
common stock in separate mailings. Elections may be made by holders of shares
of Century common stock by delivering the appropriate form of election to
American Stock Transfer & Trust Company (the "Exchange Agent"). To be
effective, a form of election must be properly completed and received by the
Exchange Agent by no later than 5:00 p.m., eastern time, on September 30, 1999
and accompanied by the Century stock certificates as to which the election is
being made or an appropriate guarantee of delivery of such certificates. A
Century stockholder who does not submit a form of election to the Exchange
Agent prior to the Election Deadline (including a holder who submits and then
revokes such stockholder's form of election and does not re-submit a form of
election and other required documents that are timely received by the Exchange
Agent), or who submits a form of election without the corresponding
certificates or a guarantee of delivery, will be deemed to have made an
election to receive Adelphia Class A common stock.

 Registration and Quotation of Adelphia Class A Common Stock

   In the merger agreement, Adelphia has agreed to use its reasonable best
efforts to register the shares of Adelphia Class A common stock to be issued as
consideration in the merger under the Securities Act, and to use its best
efforts to cause such shares to be approved for quotation on the Nasdaq
National Market. Such registration and quotation are conditions to the
obligations of Century to consummate the merger. The issuances of such shares
in the merger has been registered under the Securities Act pursuant to a
registration statement which has been declared effective.

 Covenants

   Adelphia and Century have made certain covenants in connection with the
merger. Some of these covenants include:

  .  Board of Directors. So long as the holders of Century Class B common
     stock and permitted assignees and transferees (as defined in the merger
     agreement) continue to own at least 10% of the outstanding Adelphia
     common stock, they will be entitled to nominate up to three members to
     Adelphia's board;

  .  Citizens Joint Venture. At the effective time of the merger, Adelphia
     will purchase the 50% interest in the Citizens-Century Cable Television
     Joint Venture owned by Citizens Cable Company at a price to be agreed
     upon. Adelphia and Citizens have subsequently agreed on a price of
     approximately $157.5 million, comprised of approximately $27.7 million
     in cash, approximately 1.85 million shares of Adelphia Class A common
     stock and the assumption of indebtedness. After this purchase, Adelphia
     will own 100% of the Citizens-Century Cable Television Joint Venture
     and, as a result, its interest in the TCI joint venture will increase to
     approximately 75%; and

                                       4
<PAGE>


  .  Registration and Tag-Along Rights. After the merger, the former holders
     of Century Class B common stock will have certain registration rights
     and tag-along rights with respect to the Adelphia Class A common stock
     received by them in the merger in accordance with a registration rights
     agreement to be entered into following execution of the merger
     agreement. These parties have subsequently entered into a separate
     registration rights agreement and tag-along rights agreement.

 Conditions

   We will complete the merger only if certain conditions are satisfied or
waived, including the following:

  .  approval of the merger by each class of Century stockholders;

  .  termination of the waiting period under U.S. antitrust laws (which has
     occurred);

  .  the SEC having declared effective Adelphia's registration statement
     covering the Adelphia Class A common stock that will be issued in the
     merger (which has occurred);

  .  opinions of tax counsel to the effect that the receipt of the Adelphia
     Class A common stock in the merger should be non-taxable for U.S.
     federal income tax purposes;

  .  as a condition for Adelphia, the receipt of all required consents of
     governmental authorities except where the failure to obtain any such
     required consent would not have a material adverse effect. The failure
     to obtain the required consents of franchising authorities will be
     deemed not to have a material adverse effect, and will therefore not
     prevent this condition from being satisfied, unless the required
     consents that are not obtained cover more than 50% of Century's basic
     subscribers (except that three franchises to be transferred to TCI in
     connection with the formation of the TCI joint venture and their
     approximately 86,000 basic subscribers are excluded from this
     calculation); and

  .  as a condition for Century, approval for quotation on the Nasdaq
     National Market of the shares of Adelphia Class A common stock to be
     issued in the merger.

 Termination

   Either Century or Adelphia may terminate the merger agreement if:

  .  the merger is not completed by June 5, 2000, unless the failure to
     complete the merger by that date is due to the breach of any provision
     of the merger agreement by the party seeking to terminate the merger
     agreement;

  .  a U.S. court or other governmental authority issues a non-appealable,
     final ruling prohibiting the merger, or any law or regulation makes
     consummation of the merger illegal; or

  .  the other party breaches a representation, warranty, covenant or
     agreement, or a representation or warranty of the other party becomes
     untrue, and that prevents satisfaction by June 5, 2000 of certain
     conditions to the obligations of the party seeking to terminate the
     merger agreement.

   Century and Adelphia also mutually may agree to terminate the merger
agreement prior to completion of the merger.

 Termination Payments

   If the merger agreement were terminated, other than by mutual agreement of
the parties and other than by Century because of a breach by Adelphia under
certain circumstances, then:

  .  Century would be required to reimburse Adelphia for its actual costs and
     expenses up to $10 million; and

  .  Century would be required to pay Adelphia a termination fee of $100
     million if Century were to be acquired by a third party, or to enter
     into an agreement to be acquired by a third party, within 24 months
     after the termination of the merger agreement.

 Regulatory Matters

   Adelphia and Century have made filings and taken other actions, and will
continue to take actions, necessary to obtain certain approvals from
governmental authorities in connection with the merger, including U.S.
antitrust authorities and the Federal Communications Commission. On March 26,
1999, Adelphia and Century made filings with the U.S. Department of Justice and
the Federal Trade Commission under the Hart-Scott-Rodino Antitrust Improvements
Act of 1976 (the "HSR Act"). On April 20, 1999, the waiting period under the
HSR Act was terminated. We expect to obtain all required material governmental
approvals and complete the merger subsequent to the special meetings, subject
to the satisfaction of all other closing conditions. We cannot be certain,
however, that we will obtain all required governmental approvals, or that we
will obtain these approvals without conditions that would be detrimental to
either of us.

 Accounting Treatment

   Adelphia will account for the merger as a purchase in accordance with
generally accepted accounting principles.

 Ownership of Shares after the Merger

   After giving effect to the merger, the Citizens acquisition, the
FrontierVision acquisition discussed on page 9, the pending Highland Holdings
purchase of Adelphia Class B common stock discussed on page 9 and the
conversion of Adelphia's Series C cumulative convertible preferred stock and
Series D convertible preferred stock into shares of Adelphia Class A common
stock, the former holders of Century Class A common stock and Century Class B
common stock will hold approximately 39.7% of the outstanding Adelphia Class A
common stock. This will represent approximately 16.6% of the total voting power
of all outstanding Adelphia shares. The above percentages are as of August 6,
1999, and are based on approximately 122,500,000 shares of Adelphia Class A
common stock and 17,006,300 shares of Adelphia Class B common stock outstanding
as of that date after giving effect to the transactions described above and
assume that all Century stock options will be exercised prior to the merger.

 Interests of Certain Persons in the Transactions

   When considering the recommendations of Century's board, you should be aware
that the executive officers and directors of Century have certain interests in
the merger that may be different from your interests as stockholders. Some of
them have such interests in their capacities as record or beneficial owners of,
or holders of the power to vote, shares of Century Class B common stock. The
holders of the Century Class B common stock are Dr. Tow, who is the Chairman
and Chief Executive Officer of Century, and two trusts established by Dr. Tow
and Claire Tow, who is a director of Century and the spouse of Dr. Tow. David
Rosensweig, who is a director and the Secretary of Century, is the sole trustee
of one of these trusts. The trustees of the other trust are Dr. Tow, Claire Tow
and Mr. Rosensweig. The holders of the Century Class B common stock will
receive a control premium of approximately 9% (assuming receipt of the cash
consideration) for their shares of Century Class B common stock compared to the
price being paid for the Century Class A common stock in the merger. The
outstanding shares of Century Class B common stock have approximately 93% of
the total combined voting power of the outstanding Century Class A common stock
and the outstanding Century Class B common stock, represent a majority
(approximately 54%) of the total number of outstanding shares of Century Class
A common stock and Century Class B common stock and have the power to elect all
but one member of the Century board. The holders of the Century Class B common
stock will also have the right to nominate up to three directors to Adelphia's
board following the merger. Certain directors and officers of Century have been
granted options to purchase shares of Century Class A common stock and
restricted stock awards of shares of Century Class A common stock which have
not yet fully vested. Completion of the merger will cause the unvested portions
of these grants to vest early, at the effective time of the merger.

 Votes Required

   Approval of the issuance of shares of Adelphia Class A common stock in the
merger requires the favorable vote of holders of a majority of the votes of all
outstanding shares of both classes of Adelphia common stock entitled to vote
and represented at the meeting, voting together as one class. Certain holders
of Adelphia Class B common stock have agreed with Century to vote in favor of
matters necessary to approve the merger. See "The Merger Agreement And Related
Agreements--The Rigas Class B Voting Agreement" on page 82.

   In order for the merger agreement to be approved by Century's stockholders,
each of the following must be voted in favor of approval of the merger
agreement:

  .  a majority of the votes cast by the holders of Century Class A common
     stock entitled to vote at the special meeting, and

  .  a majority of the votes cast by the holders of Century Class B common
     stock entitled to vote at the special meeting.

   The holders of all of the shares of Century Class B common stock have agreed
to vote their Century Class B shares in favor of the merger. See "The Merger
Agreement and Related Agreements--The Class B Voting Agreement" on page 81.

 Voting Agreements

   As noted above, in connection with the execution of the merger agreement,
all of the Century Class B stockholders and certain Adelphia Class B
stockholders entered into voting agreements to vote their shares of their
respective companies' Class B common stock in favor of the merger and each of
the other transactions contemplated by the merger agreement. As of August 6,
1999, the Adelphia Class B stockholders who are parties to the voting agreement
had the power to vote shares representing approximately 77.1% of the total
votes entitled to be cast by the holders of the Adelphia common stock. The
Century Class B stockholders have also agreed to vote their Class B shares
against any proposal for the acquisition of Century by a third party. These
obligations will continue until June 5, 2000, unless the merger agreement
terminates prior to that date in accordance with its terms or the merger is
consummated. As of August 6, 1999, the Century Class B stockholders had the
power to vote shares representing approximately 93% of the total votes entitled
to be cast by the holders of Century common stock.

 Material Federal Income Tax Consequences to Century Stockholders

   Century and Adelphia will receive opinions from their respective counsel at
the closing of the merger that the merger should be treated as a
"reorganization" within the meaning of the Internal Revenue Code. However, the
U.S. federal income tax consequences of the merger to you will depend upon the
form of consideration you receive in the merger.

   If you receive solely Adelphia Class A common stock (and cash in lieu of a
fractional share) in exchange for your Century common stock, then you should
not recognize any gain or loss, except possibly with respect to the fractional
share. If you receive solely cash, then you will generally recognize gain (and
likely will be permitted to recognize loss) equal to the difference between the
amount of cash you receive and your basis in your Century common stock. The tax
treatment of any gain will depend upon your individual circumstances.

   If you receive a combination of Adelphia Class A common stock and cash
(other than cash in lieu of a fractional share) in exchange for your Century
common stock, then you should generally recognize gain in an amount equal to
the lesser of the total amount of cash received or the amount of gain realized
on the exchange, but you are not permitted to recognize a loss. Any gain
recognized may be treated as a dividend.

 May 1999 Cable System Swap Agreements

   On May 26, 1999, Adelphia announced that it had agreed to exchange certain

Angeles, California and West Palm/Fort Pierce, Florida. In exchange, Comcast
and Jones would receive systems currently owned, managed or under contract to
be acquired by Adelphia serving approximately 464,000 subscribers in suburban
Philadelphia, Pennsylvania, Ocean County, New Jersey, Ft. Myers, Florida,
Michigan, New Mexico and Indiana. All systems involved in the transactions will
be valued by agreement between the parties or, following a failure to reach
agreement, by independent appraisals, and any difference in relative value will
be funded with cash or additional cable systems. The system exchanges are
subject to customary closing conditions and regulatory approvals and are
expected to close by mid-2000.

   On April 28, 1999, Adelphia consummated an offering of $350 million of 7
7/8% Senior Notes due 2009. Net proceeds from this offering, after deducting

capital expenditures and investments.

 Pending Harron Acquisition

   On April 12, 1999, Adelphia entered into a definitive agreement to purchase
the cable television systems owned by Harron Communications Corp. for
approximately $1.2 billion in cash. This transaction is subject to customary
closing conditions. As of December 31, 1998, Harron had approximately 294,000
basic subscribers after giving effect to recent and pending acquisitions by
Harron involving systems with approximately 9,000 basic subscribers. The
closing is expected to occur early in the calendar quarter ending December 31,
1999.

 Pending Highland Holdings Purchase of Class B Common Stock

   On April 9, 1999, Adelphia entered into a stock purchase agreement with
Highland Holdings, a general partnership controlled by members of the family of
John J. Rigas, in which Adelphia agreed to sell to Highland Holdings, and
Highland Holdings agreed to purchase a minimum of $250 million and, at the
option of Highland Holdings, up to $375 million of Adelphia Class B common
stock. The purchase price for the Class B common stock will be $60.76 per
share, which is equal to the public offering price in Adelphia's April 28, 1999
public offering of Class A common stock described above less the underwriting
discount, plus an interest factor. Closing under this stock purchase agreement
is to occur on or prior to January 23, 2000 as determined by Highland Holdings
in its discretion.

common stock. As a result of this acquisition, approximately $1.1 billion of
FrontierVision debt would become part of Adelphia's total indebtedness. The
transaction is subject to customary closing conditions. As of December 31,

Adelphia Class A common stock and 20,000 shares of its Series C cumulative
convertible preferred stock which were convertible into an additional 2,358,490

shares of Adelphia Class A common stock on a fully converted basis. Adelphia
also agreed to acquire Telesat's equity interests in Olympus Communications,
L.P., a joint venture between Adelphia and Telesat. The acquisition is subject
to applicable third party approvals and is expected to close during the third

            SELECTED HISTORICAL AND PRO FORMA FINANCIAL INFORMATION

 Historical Financial Information

   We are providing or incorporating by reference in this joint proxy
statement/prospectus selected historical financial information for Adelphia and
Century to help you in your analysis of the financial aspects of the merger.

   We derived this information from the audited and unaudited financial
statements of Adelphia and Century for the periods presented. The information
is only a summary and you should read it together with the financial
information included or incorporated by reference in this joint proxy
statement/prospectus. See "Where You Can Find More Information" on page 103.

 Unaudited Pro Forma Condensed Consolidated Financial Information

   We are also providing unaudited pro forma condensed consolidated financial
information in this joint proxy statement/prospectus to show you how Adelphia
might have looked if the merger, the pending acquisitions of FrontierVision,
Harron and Telesat's interests in Olympus and various financing transactions
had been completed on April 1, 1998 for statement of operations purposes and as
of March 31, 1999 for balance sheet purposes. See page 84.

   The pro forma financial information was prepared using the purchase method
of accounting.

   If Adelphia had actually completed the merger and the acquisitions of
FrontierVision, Harron and Telesat's interests in Olympus in prior periods, the
acquired companies might have performed differently. You should not rely on the
pro forma financial information as an indication of the results that Adelphia
would have achieved if the transactions had taken place earlier or the future
results that the companies will experience after completion of the
transactions.

   In the table below, Adelphia provides you with its selected historical
consolidated financial data. Adelphia prepared this information using its

                                  RISK FACTORS

Risk Factors Relating To The Merger

Adelphia May Not           Integrating the operations of Century with those of
Successfully Integrate     Adelphia after the merger may be difficult and time
Century's Business         consuming. After the merger has been completed,
Operations                 Adelphia may integrate, among other things, the
                           product and service offerings, the product
                           development, sales and marketing, research and
                           development, administrative and customer service
                           functions, and the management information systems
                           of Century with those of Adelphia. The integration
                           of Century will require substantial attention from
                           management. The diversion of management attention
                           and any difficulties encountered in the transition
                           and integration processes could have an adverse
                           effect on the revenues, levels of expenses and
                           operating results of the combined company. Adelphia
                           may experience difficulties in the course of the
                           integration process, such as the loss of key
                           personnel. Adelphia may fail to manage this
                           integration effectively or to achieve any of the
                           anticipated benefits that both companies hope will
                           result from this integration.

Adelphia May Need To       Century and its subsidiaries have substantial
Refinance Century          indebtedness. At May 31, 1999, Century and its
Indebtedness               subsidiaries had long-term debt of approximately
                           $2.0 billion and current maturities of $20.1
                           million, including $1.87 billion principal amount
                           of public indebtedness under nine indentures, $89
                           million of indebtedness under credit agreements
                           entered into by Century's subsidiaries and various
                           banks and $80 million of indebtedness under a note
                           agreement entered into by a subsidiary of Century.

                           Under the indentures for Century's public notes,
                           the merger will require the Adelphia merger
                           subsidiary to make an offer to purchase the public
                           notes if the merger results in the public notes
                           being downgraded to a specified level by certain
                           national rating agencies. Upon announcement of the
                           merger, certain rating agencies announced that the
                           Century notes were under review with a view to a
                           downgrade to a level which would not require the
                           Adelphia merger subsidiary to make an offer to
                           repurchase such public notes. In the event that the
                           public notes were to be downgraded to a level
                           beyond that announced by the rating agencies upon
                           disclosure of the merger, the Adelphia merger
                           subsidiary that survives the merger, would be
                           required to make an offer to repurchase the public
                           notes at 101% of the amount of the notes. In the
                           event that a significant amount of notes were
                           tendered for repurchase, this could materially
                           decrease Adelphia's liquidity.

                           Without the consent of the lenders to Century's
                           subsidiaries, the merger will violate certain
                           covenants contained in the Century credit
                           agreements. As a result, Adelphia will either
                           secure a waiver from the lenders under these credit
                           agreements or will refinance such credit agreements
                           with new or existing credit facilities. Although
                           Adelphia currently has sufficient liquidity under
                           its existing credit facilities to refinance the
                           borrowings under Century's credit agreements,
                           Adelphia is seeking consents to keep some or all of
                           Century's credit agreements in place. In the event
                           that these consents cannot be obtained upon
                           reasonable terms,

                                       18

                           Adelphia could seek to refinance some or all of
                           them under one or more new facilities in order to
                           preserve its existing liquidity. There can be no
                           assurance, however, that Adelphia will be able to
                           obtain these consents or refinance these credit
                           agreements under any terms or on terms acceptable
                           to Adelphia. As a result, failure to obtain the
                           required consents or to refinance these credit
                           agreements could materially decrease Adelphia's
                           liquidity.

Value Of Adelphia Stock    The number of shares of Adelphia common stock to be
To Be Received In The      received in the merger for each share of Century
Merger May Fluctuate       common stock is fixed. Therefore, because the
                           market price of Adelphia Class A common stock is
                           subject to fluctuation, the value at the time of

                           be received by Century stockholders will depend on
                           the market price of Adelphia Class A common stock
                           at that time. There can be no assurance as to the
                           market value at the time of the merger of the
                           Adelphia Class A common stock to be received by
                           Century stockholders. For historical and current
                           market prices of Adelphia Class A common stock, see

                           Information" on page 17.

Adelphia Expects To        Adelphia expects to incur restructuring and
Incur Potentially          integration costs from integrating Century's
Significant Integration    operations with those of Adelphia. These costs may
Costs In Connection With   be substantial and may include costs for employee
The Merger                 severance, facilities closures, and relocation and
                           disposition of excess equipment. Adelphia has not
                           yet determined the amount of these costs. Adelphia
                           expects to charge these costs to operations in the
                           quarter in which the merger is completed, and this
                           will hurt Adelphia's operating results for that
                           quarter.

The Failure To Satisfy     The merger may not close unless several conditions

                              the controlling stockholders of Adelphia have
                              agreed to vote in favor of the merger, the

                           and expenses up to $10 million. In addition,
                           Century would be required to pay Adelphia a
                           termination fee of $100 million if Century were to
                           be acquired by a third party, or to enter into an

                           might decline, assuming that current market prices
                           reflect a market assumption that the merger will be
                           completed; and Century would still have to pay its
                           costs related to the merger, such as legal,
                           accounting and financial advisory fees.

 Risk Factors Relating To Adelphia

   Before you approve the merger in which you will receive Adelphia's Class A
common stock, you should be aware that there are various risks associated with
investing in Adelphia, including those described below. You should carefully
consider these risk factors together with all of the other information included
in this joint proxy statement/prospectus before you decide to approve the
merger.

High Level Of              Adelphia has a substantial amount of debt. Adelphia
Indebtedness               borrowed this money to purchase and to expand its
                           cable systems and other operations and, to a lesser
                           extent, for investments and loans to its
                           affiliates. At March 31, 1999, Adelphia's
                           indebtedness totaled approximately $3.6 billion.
                           This included approximately:

                           had, as of March 31, 1999, approximately
                           $550 million of debt. Olympus will be consolidated
                           with Adelphia upon completion of Adelphia's
                           proposed acquisition of Telesat's equity interests
                           in Olympus. That acquisition is expected to close

                           $456 million owed under three indentures for public

                           reorganization or bankruptcy laws. Adelphia
                           believes that its business will continue to
                           generate cash and that it will be able to obtain
                           new loans to meet its cash needs. However, the

                           In addition, because Adelphia's systems are
                           operated under non-exclusive franchises, other
                           applicants may obtain franchises in Adelphia
                           franchise areas. For example, some regional Bell
                           operating companies and local telephone companies
                           have facilities which are capable of delivering
                           cable television service and could seek competitive
                           franchises.

                           The equipment which telephone companies use in
                           providing local exchange service may give them
                           competitive advantages over Adelphia in
                           distributing video to home televisions. The
                           regional Bell operating companies and other
                           potential competitors have much greater resources
                           than Adelphia and would constitute formidable
                           competition for its cable television business.
                           Adelphia cannot predict either the extent to which
                           competition will continue to materialize or, if
                           such competition materializes, the extent of its
                           effect on Adelphia's cable television business.

                           Adelphia's cable television systems also face
                           competition from other communications and
                           entertainment media, including conventional off-air
                           television broadcasting services, newspapers, movie

                           which competition may affect it.

                           business is subject to strong competition and
                           potential competition from a number of sources.
                           With respect to high speed cable modem service,
                           telephone companies are beginning to implement
                           various digital subscriber line services (xDSL)
                           that allow high speed internet access services to
                           be offered over telephone lines. DBS companies
                           offer high speed Internet access over their
                           satellite facilities and other terrestrial based
                           wireless operators (e.g., MMDS) are beginning to
                           introduce high speed access as well. In addition,
                           there are now a number of legislative and FCC
                           initiatives and efforts seeking to require cable
                           television operators to provide open access to
                           their facilities to competitors that want to offer
                           cable modem services. With respect to dial up
                           Internet access services, there are numerous
                           competitive Internet Service Providers (ISPs) in
                           virtually every franchise area. The local telephone
                           exchange company typically offers ISP services, as
                           do a number of other nationally marketed ISPs such
                           as America Online, Compuserve and AT&T Worldnet.
                           Adelphia cannot predict the extent to which
                           competition will continue to materialize or, if
                           such competition materializes, the extent of its

                           Adelphia believes that local telephone companies
                           will gain increased pricing flexibility from
                           regulators as competition increases. Hyperion's

Adelphia Is Subject To
Extensive Regulation       The cable television industry and the provision of
                           local telephone exchange services are subject to
                           extensive regulation at the federal, state and
                           local levels, and many aspects of such regulation
                           are currently the subject of judicial proceedings
                           and administrative or legislative proposals. In
                           particular, the FCC adopted regulations that limit
                           Adelphia's ability to set and increase rates for
                           its basic service package and for the provision of
                           cable television-related equipment. The law permits
                           certified local franchising authorities to order
                           refunds of rates paid in the previous 12-month
                           period determined to be in excess of the permitted
                           reasonable rates. It is possible that rate
                           reductions or refunds of previously collected fees
                           may be required in the future. In addition, the FCC
                           has commenced a proceeding to determine whether
                           cable operators will be required to carry the
                           digital signals of broadcast television stations.
                           Such a requirement could require the removal of
                           popular programming services with materially
                           adverse results for cable operators.

   Adelphia's cable
television and
telecommunications
businesses are heavily
regulated as to rates it
can charge and other
matters. This regulation
could limit Adelphia's
ability to increase
rates, cause it to
decrease then current
rates or require it to
refund previously
collected fees.

                           Adelphia must comply with rules of the local
                           franchising authorities to retain and renew its
                           cable franchises, among other matters. There can be
                           no assurances that the franchising authorities will
                           not impose new and more restrictive requirements as
                           a condition to franchise renewal. Similarly,
                           Hyperion is subject to state and local regulations
                           and in some cases must obtain appropriate
                           certifications and/or local franchises to construct
                           facilities and offer services. There can be no
                           assurance that Hyperion's state and local
                           regulators will not impose new and more restrictive
                           requirements as a condition to renew any required
                           certifications and franchises.

                           Proposals are currently before Congress and the FCC
                           to require cable operators to provide equal access
                           over their cable systems to other ISPs. To date,
                           the FCC has declined to impose such requirements.
                           This same "open access" issue is being considered
                           by some local franchising authorities as well.
                           Recently, a federal district court in Portland,
                           Oregon, upheld the authority of the local
                           franchising authority to impose an open access
                           requirement in connection with a cable television
                           franchise transfer and that decision has been
                           appealed to the U.S. Court of Appeals for the Ninth
                           Circuit. If Adelphia is required to provide such
                           open access, it could adversely impact Adelphia's
                           anticipated revenues from high-speed cable modem
                           services and could complicate marketing and
                           technical issues associated with the introduction
                           of such services.

   The federal Telecom-    The federal Telecommunications Act of 1996
munications Act of 1996    substantially changed federal, state and local laws
may have a significant     and regulations governing Adelphia's cable
impact on Adelphia's ca-   television and telecommunications businesses. This
ble television and tele-   law could materially affect the growth and
phone businesses.          operation of the cable television industry and the
                           cable services Adelphia provides. Although this
                           legislation may lessen regulatory burdens, the
                           cable television industry may be subject to new
                           competition as a result. There are numerous
                           rulemakings that have been and continue to be
                           undertaken by the FCC which will interpret and
                           implement the provisions of this law. Furthermore,
                           portions of this law have been, and likely other
                           portions will be, challenged in the courts.
                           Adelphia cannot predict the outcome of such
                           rulemakings or lawsuits or the short- and long-term
                           effect, financial or otherwise, of this law and FCC
                           rulemakings on Adelphia.

                           Similarly, the federal Telecommunications Act of
                           1996 removes entry barriers for all companies and
                           could increase substantially the number of
                           competitors offering comparable services in
                           Hyperion's markets or potential markets.
                           Furthermore, Adelphia cannot guarantee that rules
                           adopted by the FCC or state regulators or other
                           legislative or judicial initiatives relating to the
                           telecommunications industry will not have a
                           material adverse effect on Hyperion.

Unequal Voting Rights Of   Adelphia has two classes of common stock--Class A
Stockholders               common stock which carries one vote per share and
                           Class B common stock which carries ten votes per
                           share. The shares that Century's stockholders will
                           receive in the merger are shares of Class A common
                           stock. Under Adelphia's Certificate of
                           Incorporation, the shares of Class A common stock
                           elect only one of Adelphia's eight directors.

Control Of Voting Power    As of June 1, 1999, the Rigas family beneficially
By The Rigas Family        owned shares representing about 42% of the total
                           number of outstanding shares of both classes of
                           Adelphia's common stock and about 77% of the total
                           voting power of Adelphia's shares. The public holds
                           a majority of the outstanding shares of Class A
                           common stock, although the Rigas family also owns
                           about 30% of those shares as of June 1, 1999. The
                           Rigas family owns about 99% of Adelphia's shares of
                           Class B common stock. The Rigas family also owns
                           shares of Adelphia's 8 1/8% Series C cumulative
                           convertible preferred stock which, if converted,
                           would increase its voting power and beneficial
                           ownership. The Rigas family also has agreed to
                           acquire 4,114,549 shares of Class B common stock,
                           and has rights to acquire up to an additional
                           2,057,275 shares of Class B common stock, which if
                           purchased would increase its beneficial ownership
                           and voting power. As a result of the Rigas family's
                           stock ownership and an agreement among the Class B
                           stockholders, members of the Rigas family have the
                           power to elect seven of eight Adelphia directors
                           and, if they converted their convertible preferred
                           stock, might be able to elect all eight directors.
                           In addition, the Rigas family could control
                           stockholder decisions on other matters such as
                           amendments to Adelphia's Certificate of
                           Incorporation and Bylaws, and mergers or other
                           fundamental corporate transactions.

   The Rigas family can
control stockholder
decisions on very
important matters.

                           present a conflict of interest with Adelphia, such
                           as how much time Adelphia's executive officers

                           Adelphia's public debt indentures contain covenants
                           that place some restrictions on transactions
                           between Adelphia and its affiliates.

                           been pledged by members of the Rigas family in
                           connection with margin loans made to members of the
                           Rigas family. These pledgees could freely sell any
                           shares acquired upon a foreclosure.

Adelphia's Acquisitions    Because Adelphia is experiencing a period of rapid

Risks                      responsibilities of management personnel, have
                           increased. Adelphia's ability to manage such
                           expansion effectively will require it to continue
                           to expand and improve its operational and financial
                           systems and to expand, train and manage its
                           employee base.

                           The merger, the FrontierVision and Harron
                           transactions and some of Adelphia's other recent
                           acquisitions involve the acquisition of companies
                           that have previously operated independently.
                           Adelphia may not be able to integrate the
                           operations of these companies without some level of
                           difficulty, such as the loss of key personnel.
                           There is no guarantee that Adelphia will be able to
                           realize the benefits expected from the integration
                           of operations from these transactions. These same
                           risks apply to integration of Century's business
                           after the merger. See "Risk Factors Relating To The
                           Merger--Adelphia May Not Successfully Integrate
                           Century's Business Operations."

                           Because Century, FrontierVision and Harron are in
                           the same industry as Adelphia, they are generally
                           subject to the same risks as Adelphia, such as
                           those relating to competition, regulation, year
                           2000 issues and technological developments.

                           Adelphia's computerized business applications that
                           could be adversely affected by the year 2000 issue
                           include:

                           .  facility systems.

                           System failure or miscalculation could result in an
                           inability to process transactions, send invoices,
                           accept customer orders or provide customers with
                           products and services. Although Adelphia is
                           evaluating the impact of the year 2000 issue on its
                           business and is seeking to implement necessary
                           solutions, this process has not been completed.

                           There can be no assurance that the systems of other
                           companies on which Adelphia's systems rely will be
                           year 2000 ready. The systems of other companies
                           also could become incompatible with Adelphia's
                           systems as a result of implementation of year 2000
                           solutions. Adelphia's failure or a third-party's
                           failure to become year 2000 ready, or its inability
                           to become compatible with third parties with which
                           it has a material relationship, including parties
                           acquired by Adelphia, may have a material adverse
                           effect on Adelphia, including significant service
                           interruption or outages; however, Adelphia cannot
                           currently estimate the extent of any such adverse
                           effects.

Risk Factors Relating To Century

   In considering whether or not to vote in favor of the merger, holders of
Century common stock and Adelphia common stock should consider the following
risk factors pertaining to Century.

High Level Of              In recent years, Century and its subsidiaries have
Indebtedness               incurred substantial indebtedness in connection
                           with the acquisition, upgrade and extension of
                           cable television systems. At May 31, 1999, Century
                           and its subsidiaries had long-term debt of
                           approximately $2.0 billion and current maturities
                           of $20.1 million. In addition to an aggregate of
                           $1.87 billion in public debt instruments of
                           Century, certain subsidiaries of Century have
                           entered into credit agreements providing for an
                           aggregate of approximately $1.2 billion of
                           potential borrowing capacity for cable operations.
                           At May 31, 1999, approximately $89 million of that
                           aggregate availability had been drawn down.
                           Approximately $875 million of this borrowing
                           capacity terminates under two credit facilities on
                           August 31, 1999.

   Century owes
approximately $2.0
billion.

   Century's high level    Century's high level of indebtedness can have
of indebtedness can have   important adverse consequences. It requires Century
important adverse          to spend a substantial portion of the cash it gets
consequences.              from its business to repay the principal and
                           interest on these debts. If Century did not have to
                           use these funds to repay these debts, it could use
                           these funds for general corporate purposes. Its
                           ability to obtain new loans for working capital,
                           capital expenditures, acquisitions or capital
                           improvements may be limited by its current level of
                           debt. In addition, having such a high level of debt
                           could limit its ability to react to changes in its
                           industry and to economic conditions generally.

Century Will Require       The cable television business is capital intensive.
Substantial Additional     Century will require additional funds from third
Financing As Well As       party financing and other sources for its working
Refinancing of Existing    capital requirements, capital expenditure needs and
Debt                       debt service obligations.

                           In the past, Century has funded the principal
                           obligations on its long-term debt by refinancing
                           the principal with the issuance of debt securities
                           in the public market and to private institutions as
                           well as internally generated cash flow and the sale
                           of certain business segments. There can be no
                           assurance that Century will continue to be able to
                           obtain financing on satisfactory terms in the
                           future. Principal payments of $20.1 million, $174.6
                           million and $239.1 million are due under Century's
                           debt instruments beginning in fiscal 2000, 2001 and
                           2002, respectively. Century will need to refinance
                           certain of such obligations on or before such time.
                           There can be no assurance that Century will be
                           successful in any such refinancing or that the
                           terms of any such refinancing will be favorable to
                           Century. In addition, the indentures for Century's
                           outstanding issues of public notes impose certain
                           restrictions on the incurrence of additional
                           indebtedness.

                           until such time as the operations of its cable
                           television systems can generate sufficient earnings
                           to offset the charges, including depreciation and

                           intercompany indebtedness, to grant liens on their
                           assets or to pay dividends to Century. These credit
                           agreements also require these subsidiaries to meet
                           certain operating and financial tests, including
                           the maintenance at certain prescribed levels of
                           various financial ratios. A note agreement entered
                           into by a subsidiary of Century imposes similar
                           restrictions and requirements. The indentures
                           governing Century's public notes also contain
                           various restrictive covenants, including: (1)
                           restrictions on mergers, sales and consolidations;
                           (2) restrictions on dividends, redemptions or
                           repurchases of Century's capital stock or the
                           capital stock of any of its affiliates;
                           (3) limitations on transactions with or investments
                           in affiliates; (4) restrictions on the ability to
                           make loans to, or act as guarantor for, certain of
                           its subsidiaries and affiliates; and (5)
                           limitations on the incurrence of additional
                           indebtedness. Century's ability to comply with
                           these covenants may be affected by events beyond
                           its control.

                           In the event of a default under the agreements
                           governing Century's public debt, the holders of
                           such debt or the trustee acting on their behalf
                           could elect to declare all of such debt securities,
                           together with accrued interest, to be due and
                           payable. There can be no assurance that the assets
                           of Century would be sufficient to repay all such
                           outstanding debt.

Competition                The telecommunications services provided by Century
                           are subject to strong competition and potential
                           competition from various sources. Century's cable
                           television systems compete with other means of
                           distributing video to home television such as
                           Direct Broadcast Satellite Systems, commonly known
                           as DBS systems, and Multichannel Multipoint
                           Distribution systems, commonly known as wireless
                           cable. Some of the regional Bell telephone
                           operating companies and other local telephone
                           companies are in the process of entering the video-
                           to-home business and several have expressed their
                           intention to enter the video-to-home business.

   Century's business is
subject to strong
competition from many
sources, including from
companies with much
greater resources than
Century. This
competition could
adversely affect revenue
or revenue growth.

                           In addition, because Century's cable systems are
                           operated under non-exclusive franchises, other
                           applicants may obtain franchises in Century's
                           franchise areas. For example, some regional Bell
                           operating companies and local telephone companies
                           have facilities which are capable of delivering
                           cable television service and could seek competitive
                           franchises.

                           The equipment which telephone companies use in
                           providing local exchange service may give them
                           competitive advantages over Century in distributing
                           video to home televisions.

                           The regional Bell operating companies and other
                           potential competitors have much greater resources
                           than Century and would constitute formidable
                           competition for its cable television business.
                           Century cannot predict either the extent to which
                           competition will continue to materialize or, if
                           such competition materializes, the extent of its
                           effect on Century's cable television business.

                           Century's cable television service also faces
                           competition from other communications and
                           entertainment media, including conventional off-air
                           television broadcasting services, newspapers, movie
                           theaters, live sporting events and home video
                           products. Century cannot predict the extent to
                           which competition may affect it.

                           Century's cable modem and dial up Internet access
                           business is subject to strong competition and
                           potential competition from a number of sources.
                           With respect to high speed cable modem service,
                           telephone companies are beginning to implement
                           various digital subscriber line services (xDSL)
                           that allow high speed internet access services to
                           be offered over telephone lines. DBS companies
                           offer high speed Internet access over their
                           satellite facilities and other terrestrial based
                           wireless operators (e.g., MMDS) are beginning to
                           introduce high speed access as well. In addition,
                           there are now a number of legislative initiatives
                           and efforts at

                           facilities to competitors that want to offer cable
                           modem services. With respect to dial up Internet
                           access services, there are numerous competitive
                           ISPs in virtually every franchise area. The local
                           telephone exchange company typically offers ISP
                           services, as do a number of other nationally
                           marketed ISPs such as America Online, Compuserve
                           and AT&T Worldnet. Century cannot predict the
                           extent to which competition will continue to

                           addition, the FCC has commenced a proceeding to
                           determine whether cable operators will be required
                           to carry the digital signals of broadcast
                           television stations. Such a requirement could
                           require the removal of popular programming services
                           with materially adverse results for cable

                           television industry and the cable services Century
                           provides. Although this legislation may lessen
                           regulatory burdens, the cable television industry
                           may be subject to new competition as a result.
                           There are numerous rulemakings that have been and
                           continue to be undertaken by the FCC which will
                           interpret and implement the provisions of this law.
                           Furthermore, portions of this law have been, and
                           likely other portions will be, challenged in the
                           courts. Century cannot predict the outcome of such
                           rulemakings or lawsuits or the short- and long-term
                           effect, financial or otherwise, of this law and FCC
                           rulemakings on Century.

                           Proposals are currently before Congress and the FCC
                           to require cable operators to provide equal access
                           over their cable systems to other ISPs . To date,
                           the FCC has declined to impose such requirements.
                           This same "open access" issue is being considered
                           by some local franchising authorities as well.
                           Recently, a federal district court in Portland,
                           Oregon, upheld the authority of the local
                           franchising authority to impose an open access
                           requirement in connection with a cable television

                           U.S. Court of Appeals for the Ninth Circuit. If
                           Century is required to provide such open access, it
                           could adversely impact Century's anticipated
                           revenues from high-speed cable modem services and
                           could complicate marketing and technical issues
                           associated with the introduction of such services.

                           degrees, the manner in which cable television
                           systems operate. Century cannot predict at this
                           time either the outcome of these proceedings or
                           their impact upon the cable television industry.
                           Moreover, changes in the regulatory and legislative
                           environment are constantly occurring. Century
                           cannot predict the effect that ongoing or future
                           developments may have on the cable television
                           industry generally or Century specifically.

And David Rosensweig       trusts established by Dr. Tow and Claire Tow, had
                           the power to vote shares of Century Class A common
                           stock and Century Class B common stock which, in
                           the aggregate, constituted approximately 93% of the
                           combined voting power of the Century Class A common
                           stock and the Century Class B common stock. This
                           voting power gives them the power to elect all but
                           one member of the Century board. It also gives them
                           the power to control the vote on all other matters
                           submitted to a vote of Century's stockholders,
                           except where separate class votes by the holders of
                           the Century Class A common stock and the Century
                           Class B common stock are required by law (as in the

Executive Officers Have
Terminated Employment      Century has employment agreements with the
Agreements                 following executive officers: Dr. Leonard Tow
                           (Chairman and Chief Executive Officer), Bernard P.
                           Gallagher (President and Chief Operating Officer),
                           Scott N. Schneider (Chief Financial Officer, Senior
                           Vice President and Treasurer) and Michael G. Harris
                           (Senior Vice President, Engineering). The terms of
                           these employment agreements expire on June 30,
                           2003, except that Dr. Tow's agreement continues for
                           an additional five-year advisory period.

                           Each of these employment agreements is terminable
                           by the executive officer upon a "change of control"
                           or a "threatened change of control" of Century. One
                           of the events that is considered to be a threatened
                           change of control under each employment agreement
                           is the acquisition by any person of securities of
                           Century such that the person files or is required
                           to make a filing pursuant to Regulation 13D under
                           the Securities Exchange Act of 1934. Such an event
                           has occurred and, therefore, for purposes of these
                           employment agreements, a "threatened change of
                           control" has occurred. Subsequent to May 31, 1999,
                           each of these executive officers has exercised his
                           right to terminate his employment agreement but has
                           agreed to continue working for Century through the
                           closing of the merger. The decision by any of the
                           executive officers not to continue working for
                           Century may have an adverse effect on Century.

                           Pursuant to each employment agreement, upon such
                           termination, the executive officer is entitled to
                           receive his base salary through the end of the term
                           of his employment agreement, an annual cash bonus
                           for the remainder of the term equal to his most
                           recently awarded cash bonus, continuation of
                           medical, dental, life and disability insurance for
                           the remainder of the term on the same basis as
                           provided while the agreement was in effect and the
                           use of office space for one year. In addition, upon
                           termination, all of his Century stock options vest
                           and become exercisable and the restrictions on all
                           of his shares of restricted stock of Century lapse.
                           As a result, approximately 260,000 options have
                           vested and become exercisable and approximately
                           599,000 shares of restricted stock have become
                           unrestricted. In addition, Leonard Tow is entitled
                           to receive certain benefits associated with his
                           life insurance arrangement with Century as well as
                           additional benefits associated with and provided to
                           him during the course of his employment, including
                           the right to receive a cash payment from Century
                           equal to the difference of the fair market value
                           and the exercise price of his unexercised options.
                           This cash payment is, in part, in lieu of
                           acceleration of the vesting of a portion of his
                           options which acceleration would otherwise be
                           afforded to him under the merger agreement.

                           Additional information regarding these employment
                           agreements and the compensation received by and
                           payable to the executive officers under them is

Holding Company
Structure                  The Century parent company directly owns no
                           significant assets, other than stock in one
                           subsidiary. This creates risks regarding its
                           ability to obtain cash from its subsidiaries to
                           repay the interest and principal which it owes or
                           to pay cash dividends to stockholders in the
                           future. Century's indentures relating to public
                           debt, and the credit agreements of Century's
                           subsidiaries and other companies in which Century
                           has invested restrict their ability and the ability
                           of the companies they own to make payments to the

The Payment Of Cash        Century's credit agreements and the indentures

                           of cash dividends on Century common stock. As a
                           result, it is unlikely that you will receive a
                           return on your Century shares through the payment
                           of cash dividends.

The Year 2000 Issue        Century has undertaken a program to address the
Presents Risks To          year 2000 issue within Century and in the products
Century's Business         and services purchased from its material suppliers.
Operations In Several      Century is in the process of replacing and testing
Ways                       its most critical business systems, signal
                           delivery, accounting, and telephone answering
                           systems, with systems that do not have a year 2000
                           problem. Century has initiated formal
                           communications with its material suppliers to
                           determine the extent to which Century is vulnerable
                           to those third parties' failure to remediate their
                           own year 2000 issues. Century cannot predict the
                           outcome of other companies' remediation efforts.
                           Century is reliant on outside suppliers for signal
                           delivery, customer billing, payroll and utility
                           services.

                           The failure to address a material year 2000 issue
                           could result in an interruption in, or a failure
                           of, certain normal business activities or
                           operations. The decentralized nature of Century's
                           operations should limit the adverse impact of the
                           failure of any one system on Century as a whole.
                           Nonetheless, Century relies upon an external
                           billing service, utility companies, satellite
                           program service providers, satellite delivery
                           systems, an external payroll service, the United
                           States postal service, the financial service
                           industry and other suppliers outside of its control
                           and there can be no assurance that such suppliers
                           or other third parties will not suffer a year 2000
                           business disruption. For example, conceivable
                           negative developments would involve a failure of
                           the nation's satellite delivery systems or
                           widespread prolonged utility outages. If either of
                           such developments occurred, Century's operating
                           results would be negatively affected. The extent of
                           the effect would depend upon the geographic scope
                           and duration of the failures or outages.

                           In addition, Century is in the process of upgrading
                           or replacing some of its software to comply with
                           year 2000 readiness. The implementation of software
                           may be accompanied with risks of incompatibilities.

                           Due to the general uncertainty inherent in the year
                           2000 issue, resulting in part from the uncertainty
                           of the year 2000 readiness of Century's material
                           suppliers and their customers, Century is unable to
                           determine at this time whether the consequences of
                           year 2000 failures will have a material adverse
                           effect on Century's consolidated financial
                           condition or results of operations.

                                 THE COMPANIES

Adelphia Communications Corporation

   Adelphia is a leader in the telecommunications industry with cable
television and local telephone operations. Adelphia's operations consist of
providing telecommunications services primarily over Adelphia's networks, which
are commonly referred to as broadband networks because they can transmit large
quantities of voice, video and data by way of digital or analog signals. As of
March 31, 1999, Adelphia owned or managed cable television systems with
broadband networks that passed in front of 3,357,400 homes and served 2,380,409
basic subscribers. After giving effect to the merger and other recent and
pending acquisitions described in "Summary--Recent Developments," Adelphia
owned or managed cable television systems with broadband networks that passed
in front of 7,667,162 homes and served 4,970,403 basic subscribers as of March
31, 1999. John J. Rigas, the Chairman, President, Chief Executive Officer and
founder of Adelphia, has owned and operated cable television systems since
1952.

   Adelphia owns cable systems in 12 states which are organized into seven
regional clusters: Western New York, Virginia, Western Pennsylvania, New
England, Eastern Pennsylvania, Ohio and New Jersey. These systems are located
primarily in suburban areas of large and medium-sized cities within the 50
largest television markets. As of March 31, 1999, the broadband networks for
these systems passed in front of 2,230,257 homes and served 1,595,536 basic
subscribers.

   Adelphia also provides management and consulting services to other
partnerships and corporations engaged in the ownership and operation of cable
television systems. John J. Rigas and members of his immediate family,
including entities they own or control, have substantial ownership interests in
these partnerships and corporations. As of March 31, 1999, the broadband
networks for cable systems owned by these Rigas family partnerships and
corporations passed in front of 178,021 homes and served 134,015 basic
subscribers.

   Adelphia also owns a 50% voting interest and nonvoting preferred limited
partnership interests in Olympus Communications, L.P. Olympus is a non-
consolidated joint venture with Telesat that operates a large cable system in
Florida. Adelphia expects to acquire the remaining equity interests in Olympus
that it does not currently own during the third calendar quarter of 1999. As of
March 31, 1999, the broadband networks for this system passed in front of
949,122 homes and served 650,858 basic subscribers.

   Through its subsidiary, Hyperion, Adelphia owns a super-regional provider of
integrated communications services in the eastern half of the United States.
Hyperion provides its customers with alternatives to the incumbent local
telephone company for local telephone and telecommunications services.
Hyperion's telephone operations are referred to as being facilities based,
which means it generally owns the local telecommunications networks and
facilities it uses to deliver these services, rather than leasing or renting
the use of another party's networks to do so. As of March 31, 1999, Hyperion
managed and operated telecommunications networks serving 39 metropolitan
statistical areas. Hyperion's Class A common stock is quoted on the Nasdaq
National Market under the symbol "HYPT."

Adelphia Acquisition Subsidiary, Inc.

   Adelphia Acquisition Subsidiary, Inc. is a Delaware corporation formed by
Adelphia on March 5, 1999 solely for the purpose of merging with Century. It is
a wholly owned, direct subsidiary of Adelphia. For ease of reference we have
referred to this subsidiary as "Merger Sub" in various places in this joint
proxy statement/prospectus. The mailing address of Merger Sub's principal
executive offices is c/o Adelphia Communications Corporation, Main at Water
Street, Coudersport, Pennsylvania 16915, and its telephone number is (814) 274-
9830.

Century Communications Corp.

   Century was incorporated in New Jersey on December 5, 1985 as the holding
company for a corporation of the same name incorporated in Texas on June 12,
1973. As used in this joint proxy statement/prospectus, unless the context
otherwise requires, the term "Century" means Century Communications Corp., a
New Jersey corporation, and its subsidiaries, and references to Century's
"fiscal year" mean the fiscal year ended May 31.

   Century is engaged primarily in the ownership and operation of cable
television systems, with significant concentrations of basic subscribers in
California, Colorado and Puerto Rico. Century recently entered into an
agreement with TCI to create an approximately 69.5%-owned joint venture which
will operate cable television systems serving approximately 772,000 basic
subscribers in the Los Angeles area. As of May 31, 1999, giving pro forma
effect to the TCI joint venture as if it had been completed prior to that date,
Century owned or operated cable television systems in 25 states and Puerto Rico
that passed in front of 2,924,000 homes and served 1,610,000 basic subscribers.
The TCI joint venture is described in more detail below.

   In addition to the TCI joint venture, certain of Century's other cable
systems referred to above are joint ventures owned 50% by Century and 50% by
unaffiliated entities. As of May 31, 1999, these 50%-owned systems passed in
front of approximately 632,000 homes and served approximately 335,000 basic
subscribers.

   One of these joint ventures is the Citizens-Century Cable Television Joint
Venture with Citizens Cable Company. This joint venture serves approximately
91,000 basic subscribers in California. At the effective time of the merger,
Adelphia will purchase Citizens Cable Company's 50% interest in this venture
for a purchase price of approximately $157.5 million, comprised of
approximately $27.7 million in cash, approximately 1.85 million shares of
Adelphia Class A common stock and the assumption of indebtedness.

   Under the recent agreement with TCI, which was executed on November 18,
1998, Century and TCI agreed to establish a strategic partnership. TCI will
contribute to the partnership all the assets related to the businesses of
certain cable television systems owned and operated by TCI serving
approximately 243,400 customers in the area of southern California. Century
will contribute to the partnership all the assets related to the businesses of
certain cable television systems owned and operated by Century serving
approximately 528,700 customers in the area of southern California, including
approximately 94,400 basic subscribers to be acquired in an exchange of cable
systems described in the paragraph below and approximately 19,000 basic
subscribers related to Century's pending acquisition of the cable television
system serving Moreno Valley and certain portions of Riverside County,
California. Century will manage the newly combined cable systems in return for
a management fee payable by the partnership and Century will own approximately
69.5% of the partnership. Adelphia's interest in the TCI joint venture will
increase to approximately 75% when Adelphia acquires, on the effective date of
the merger, Citizens Cable Company's 50% interest in the Citizens-Century Cable
Television Joint Venture.

   The exchange of cable systems referred to above will involve the exchange of
cable systems owned by Century in certain communities in northern California
for certain cable systems owned by TCI in southern California, allowing each of
them to unify operations in existing service areas. TCI will exchange its East
San Fernando Valley cable system serving approximately 94,400 basic subscribers
for Century's northern California

                                       39
<PAGE>

cable systems, serving approximately 95,900 basic subscribers in its San Pablo,
Benicia, Fairfield and Rohnert Park systems.

   The closing of the transaction between Century and TCI is subject to, among
other things, each party obtaining the required consents and all appropriate
regulatory and other approvals, including from the Federal Communications
Commission and local franchising authorities and under the HSR Act. On February
18, 1999, the waiting period under the HSR Act for Century's acquisition
terminated. On May 6, 1999, Adelphia also made the necessary filings under the
HSR Act with respect to the TCI transaction, and requested early termination.
On May 25, 1999, the FTC notified Adelphia that the waiting period under the
HSR Act was terminated for Adelphia's acquisition. Century has completed filing
the material applications seeking transfer of Century's applicable franchise
licenses with the FCC and local franchising authorities. Century cannot assure
you that it will obtain the required approvals or that the transaction will be
consummated.

   Certain information relating to directors and executive officers, executive
compensation, voting securities and the principal holders thereof and certain
relationships and related transactions as to Century is set forth or
incorporated by reference in Century's Annual Report on Form 10-K for the
fiscal year ended May 31, 1999. All of this information is incorporated herein
by this reference. Stockholders desiring copies of such document may contact

                                   THE MERGER

Special Meetings To Vote On The Merger

   Adelphia and Century are furnishing this joint proxy statement/prospectus to
their stockholders in connection with the solicitation of proxies by Adelphia
for use at the Adelphia special meeting and the solicitation of proxies by
Century for use at the Century special meeting.

   The Adelphia special meeting will be held at the Coudersport Theatre, Main
Street, Coudersport, Pennsylvania, on Friday, October 1, 1999, at 10:00 a.m.
local time. At the Adelphia special meeting, Adelphia stockholders will be
asked to vote upon the Adelphia merger proposal, which is a proposal to
approve, as required by the rules of the Nasdaq National Market, the issuance
of shares of Adelphia Class A common stock, par value $0.01 per share, to the
holders of Century common stock in connection with the merger.

   The Century special meeting will be held at the law offices of Gibson, Dunn
& Crutcher LLP, 200 Park Avenue, 48th Floor, New York, NY 10166, on Friday,
October 1, 1999, at 10:00 a.m. local time. At the Century special meeting,
Century stockholders will be asked to vote upon the Century merger proposal,
which is a proposal to approve and adopt the merger agreement.

Structure Of The Merger

   Century will merge with and into Merger Sub, with Merger Sub being the
surviving corporation in the merger and remaining a wholly owned subsidiary of
Adelphia.

   In connection with the merger:

  .  each share of Century Class A common stock, par value $.01 per share,
     will, at the election of each holder but subject to proration as
     described on pages 71-72, be exchanged for 0.77269147 of a share of
     Adelphia Class A common stock, $44.14 in cash, or a combination of cash
     and stock;

  .  each share of Century Class B common stock, par value $.01 per share,
     will, at the election of each holder but subject to proration as
     described on pages 71-72, be exchanged for 0.84271335 of a share of
     Adelphia Class A common stock, $48.14 in cash, or a combination of cash
     and stock; and

  .  no fractional shares of Adelphia Class A common stock will be issued in
     the merger. All fractional shares of Adelphia Class A common stock that
     a holder of shares of Century common stock otherwise would be entitled
     to receive as a result of the merger will be aggregated. If a fractional
     share results from such aggregation, in place of the fractional share
     the holder will be entitled to receive from Adelphia an amount in cash
     determined by multiplying the closing price of a share of Adelphia Class
     A common stock on the Nasdaq National Market on the trading day
     immediately preceding the effective date of the merger by the fraction
     of a share of Adelphia Class A common stock to which such holder would
     otherwise have been entitled.

Closing Of The Merger

   The merger will become effective when a Certificate of Merger is filed with
the Secretaries of State of each of New Jersey and Delaware. This will take
place on the closing date, which will be a date specified by Adelphia and
Century (but no later than the second business day) following the satisfaction
or waiver of the conditions to the merger (other than those conditions to be
satisfied or waived at the closing) or such other date as Adelphia, Century and
Merger Sub shall agree upon. The merger will close subsequent to the special
meetings, subject to the satisfaction of all other closing conditions. However,
delays in obtaining required consents or approvals of governmental authorities
could delay closing the merger. Adelphia and Century cannot assure you that
these consents and approvals will be obtained or when they will be obtained or
that the merger will, in fact, be completed. If the merger does not occur on or
before June 5, 2000, the merger agreement may

                                       41
<PAGE>

be terminated by either Adelphia or Century, unless the failure to complete the
merger by that date is due to the breach of any provision of the merger
agreement by the party seeking to terminate the merger agreement. See "The
Merger Agreement And Related Agreements--The Merger Agreement--Conditions to
Completing the Merger" and "The Merger--Regulatory Matters."

Background Of The Merger

   Century was incorporated in New Jersey in 1985 as the holding company for a
corporation of the same name incorporated in Texas in 1973. Over the past 25
years, Century has grown through acquisitions, as well as through upgrading,
extending and rebuilding its existing cable television systems, to be the ninth
largest operator of cable television systems in the United States, with major
clusters located in California, Colorado and Puerto Rico.

   In the last several years, the telecommunications industry, including the
cable television industry, has undergone significant changes due to
technological advances, expanded service offerings and a new regulatory
structure. The federal Telecommunications Act of 1996 fundamentally altered the
landscape in the telecommunications industry by establishing a pro-competitive,
deregulatory policy framework for both video and telecommunications services.
As a result of technological advances and the reduction of regulatory barriers,
the traditional services provided by cable television operators are expanding
beyond video programming to include enhanced video, high-speed data, Internet
access, telephony and other telecommunications services. In addition, in order
to gain necessary critical mass and increase the size of subscriber clusters,
which promotes efficient operations particularly in major metropolitan areas,
the cable television industry has been experiencing a period of unprecedented
consolidation characterized by mergers, joint ventures, acquisitions, cable
system exchanges and similar transactions.

   Consolidation in the cable industry has accelerated as the largest cable
system operators, major telecommunications corporations and others have
concluded that cable television networks offer an attractive opportunity to
deploy advanced broadband networks capable of delivering new voice and data
services to large numbers of consumers and that only the largest of cable
operators will be able to obtain critical mass in key markets and have access
to the capital necessary to compete effectively. In this environment of rapid
consolidation and escalating demands for capital expenditures needed to upgrade
plant, Century became increasingly concerned about its ability to grow and gain
critical mass as an independent company.

   In the summer of 1998, a major cable system operator approached Century and
proposed to acquire Century for consideration consisting of cash and common
stock. The proposal included a premium payable for the Century Class B common
stock. Representatives of Century and this potential acquiror discussed the
terms of a potential transaction, but no agreement was reached and the Century
board ultimately determined that it was not in the best interests of Century or
its stockholders to proceed with the sale of Century to this operator at that
time.

   Later in the summer of 1998, another major cable operator approached Century
and proposed to acquire Century for consideration consisting solely of cash.
The proposal included a premium payable for the Century Class B common stock.
Representatives of Century and this potential acquiror discussed the terms of a
potential transaction, but no agreement was reached and again the Century board
ultimately determined that it was not in the best interests of Century or its
stockholders to proceed with the transaction proposed by that potential
acquiror at that time.

   At a meeting held on December 14, 1998, after considering the historically
high valuations being offered to the larger cable systems operators in recent
acquisition transactions, the impracticability of Century itself growing
through the acquisition of a major cable system operator, Century's need to
achieve substantially greater size and the need to access additional capital
for upgrades and expansions and to deliver enhanced video, high-speed data,
telephony and other telecommunications services, as well as the unsolicited
offers received earlier in the year, the Century board determined to explore
its strategic alternatives and to retain DLJ as its financial advisor. On
December 16, 1998, Century publicly announced its board's decisions.


                                       42

   Following the public announcement, representatives of DLJ and Century met to
determine the most desirable means of soliciting bids for Century. DLJ and
Century identified the most likely strategic buyers of Century, and DLJ sent
confidentiality agreements to these potential buyers. DLJ sent a confidential
memorandum describing Century and its business to each of the potential buyers
who signed a confidentiality agreement.

   During the month of February 1999, four potential buyers, including
Adelphia, conducted due diligence with respect to Century and its business. Due
diligence generally consisted of review of documents assembled in a data room,
management presentations and site visits to Century's three main clusters of
cable systems located in Los Angeles, San Juan and Colorado Springs. Members of
Adelphia management attended a management presentation given by Century and
also made a presentation to Century regarding Adelphia at this time.

   Adelphia's due diligence was supplemented by its knowledge of Century and
its management. John J. Rigas, Chairman, CEO and President of Adelphia, and
Leonard Tow, Chairman and CEO of Century, have known each other personally and
professionally for many years. The two companies' cable television businesses
have a similar growth history and generally have been of similar size in terms
of number of basic subscribers. As a result, the two companies often have been
compared with each other by financial analysts, investors and investment
bankers. These continual comparisons have resulted in both Century and Adelphia
having a strong familiarity with each other's respective business, management
and operations.

   On February 20, 1999, DLJ invited the four potential bidders who had
conducted due diligence to submit bids for Century, and distributed two
proposed forms of merger agreement to each buyer for its consideration. One
form of merger agreement contemplated an all cash transaction. The other form
contemplated a combination cash and stock transaction.

   Three bidders, including Adelphia, submitted bids on March 2, 1999, the
designated deadline for final bids. All bids contemplated a premium for the
Century Class B common stock, and all three bidders required that the holders
of the Century Class B common stock agree to vote their shares in favor of the
merger. Two bids, one from Adelphia and one from another bidder, were
comparable in value. The initial Adelphia bid consisted of a combination of
cash, common stock and preferred stock. Another bidder offered cash only. The
third bid was below the other two. The three bidders also submitted their
proposed changes to the merger agreement.

   After discussions with DLJ concerning the economic terms of the third
bidder's proposal, and discussions with Century's counsel, Gibson, Dunn &
Crutcher LLP, concerning the third bidder's proposed changes to the merger
agreement, Century decided not to pursue further discussions with the third
bidder.

   Between March 2, 1999 and March 4, 1999, representatives of DLJ engaged in
discussions and negotiations with Adelphia and the other remaining bidder
regarding the economic terms of their bids, and Gibson Dunn engaged in
discussions and negotiations with counsel for Adelphia and the other remaining
bidder regarding their proposed changes to the merger agreement. In addition,
Century and Adelphia discussed Century's concern that the Adelphia preferred
stock would have to be discounted from its stated value when comparing the two
bids under consideration. On March 3, 1999, Adelphia revised its bid to replace
the preferred stock with additional shares of Adelphia Class A common stock. On
the same day, the other remaining bidder raised the amount of its cash only
bid. Each of the revised bids still contemplated a premium for the Century
Class B common stock. In addition, counsel for Adelphia and Gibson Dunn reached
agreement on most issues raised by Adelphia's suggested revisions in the merger
agreement, and counsel for the other remaining bidder and Gibson Dunn continued
their negotiations in an attempt to resolve the remaining issues raised by this
bidder's suggested revisions to the merger agreement.

   On March 4, 1999, the Century directors met at DLJ's offices with DLJ and
Gibson Dunn to consider the two proposals. Initially, the board met without the
presence of the directors who are holders of the Century Class B common stock,
Dr. Tow, Claire Tow and David Rosensweig (the record holder of certain shares
of

                                       43
<PAGE>

Class B common stock in his capacity as a trustee of certain trusts established
by Dr. and Mrs. Tow), and also without the presence of the other employee
directors. At this meeting, representatives of DLJ and Gibson Dunn described
the auction process, informed these directors of recent developments and
presented the two competitive proposals received. DLJ and Gibson Dunn briefly
described the third bidder's proposal. Also at this meeting, these directors
discussed the premium offered by all three bidders for the Class B common
stock, as well as the voting agreements required by all three bidders.

   At approximately 10:30 a.m. and again at approximately 1:45 p.m., the entire
Century board convened to discuss the proposed sale of Century. Representatives
of DLJ presented an extensive discussion of the auction process to date,
reviewed recent developments, presented the two bids still under consideration
and compared the economic values of these two bids. Gibson Dunn presented a
detailed comparison of the two forms of merger agreement under consideration
and reviewed the fiduciary duties of the Century board under the circumstances.
The Century board discussed the terms and conditions of the two remaining bids,
instructed DLJ to confirm that the two bids were the best and final bids from
each bidder and instructed Gibson Dunn to continue any negotiations necessary
to finalize the merger agreement with each bidder. The Century board also
considered whether Century should remain independent and attempt to compete
with the major cable systems operators on a stand-alone basis.

   Also on March 4, 1999, beginning at approximately 4:00 p.m., the Adelphia
board met to review the proposed transaction with Century. At previous Adelphia
board meetings, Adelphia's growth strategy had been discussed. At this meeting,
Adelphia management noted that the possibility of a transaction with Century
had been previously discussed from time to time at the board level, and that it
appeared that there was the potential for a transaction with Century at this
time, although an auction was ongoing. The process established by Century and
DLJ was discussed, particularly Adelphia's participation in the process to
date. It was noted that Adelphia management was very familiar with Century and
its cable television systems.

   Adelphia's management also presented to the Adelphia board information
regarding Century and its cable television systems, certain terms of the
transaction based on discussions to date, the effects of the transaction on
Adelphia and its stockholders and bondholders, the possible reactions from the
marketplace to a transaction on the proposed terms, the other pending Adelphia
transactions and other matters. Daniels advised the board that it had been
involved with management in evaluating the transaction, and made a detailed,
preliminary presentation regarding the fairness, from a financial point of
view, of the proposed transaction to Adelphia and its stockholders. Adelphia's
legal counsel reviewed with the board the merger agreement and the other
transaction documents. Toward the end of the meeting, Adelphia management
informed the board that, in response to a request from DLJ as to the status of
its offer, management was now planning to increase Adelphia's offer to a
combination of cash and Adelphia Class A common stock, with each outstanding
share of Century Class A common stock to receive approximately $9.16 in cash
and approximately .61 of a share of Adelphia Class A common stock and each
outstanding share of Century Class B common stock to receive approximately
$11.81 in cash and approximately .64 of a share of Adelphia Class A common
stock. The value of this bid was approximately $44.29 for each outstanding
share of Century Class A common stock and approximately $48.30 for each
outstanding share of Century Class B common stock, based on the closing price
of the Adelphia Class A common stock of $57.375 on March 3, 1999. No formal
board action was taken at this meeting, although the Adelphia board instructed
management to continue its discussions with Century.

   DLJ spoke with Adelphia regarding its best and final proposal and Adelphia
responded with the increased offer discussed above. DLJ also spoke with the
financial advisor to the other remaining bidder, which confirmed that the bid
previously received from the other remaining bidder was its best and final bid.

   The Adelphia board then met again on March 4, 1999 at approximately 8:30
p.m. At that time, management updated the board as to the status of matters.
Daniels made a full presentation regarding its financial analysis of Adelphia's
proposal. Salomon Smith Barney Inc., which also was very familiar with
Adelphia, the proposed transaction with Century and the cable television
industry, made a presentation regarding the proposed transaction, although no
formal opinion was presented. Daniels then delivered to the

                                       44
<PAGE>

Adelphia board its oral opinion, later confirmed in writing, that, as of such
date and based upon and subject to certain matters set forth in the opinion,
the proposed transaction was fair, from a financial point of view, to Adelphia
and its stockholders. Based on Daniels' opinion and the other information
presented or known to the Adelphia board, the board concluded that the merger
and related transactions were fair to and in the best interests of Adelphia and
its stockholders, and unanimously (with one director being absent) voted to
approve the merger, to authorize the executive officers to execute the merger
agreement and related documents and to recommend that the Adelphia stockholders
vote in favor of the issuance of the Adelphia Class A common stock in the
merger.

   The entire Century board re-convened at approximately 9:30 p.m. to consider
the Adelphia proposal and the other remaining proposal. Representatives of DLJ
compared the economic values of these two bids, and Gibson Dunn again reviewed
the terms and conditions of the two merger agreements. The Century board
considered the premium proposed to be paid to the holders of the Century Class
B common stock and the voting control and majority position of the holders of
the Century Class B common stock. The Century board determined that such
premium was consistent with recent comparable cable acquisitions and an
acceptable control premium to be paid to such holders. DLJ rendered its oral
opinion to the Century board, which oral opinion was later confirmed in
writing, that the consideration to be received by the holders of the Century
Class A common stock (other than holders who are affiliates of Century)
pursuant to the Adelphia proposal would be fair to such holders from a
financial point of view. After extended discussion, the Century board
unanimously determined to accept the Adelphia offer and that the merger with
Adelphia was in the best interests of Century and its stockholders.

   After these board of director meetings had concluded, early on the morning
of March 5, 1999 the parties executed the merger agreement and related voting
agreements and issued a joint press release announcing the execution of the
merger agreement.

   On July 12, 1999, the merger agreement was amended to provide, among other
things, for the election procedures described in this joint proxy
statement/prospectus. See "The Merger Agreement and Related Agreements--The
Merger Agreement--Consideration to be Received for Century Common Stock in the
Merger" on page 70. Prior to such amendment, the merger agreement did not
include the election procedures but, rather, provided that at the effective
time of the merger, each outstanding share of Century Class A common stock
would be converted into approximately $9.16 in cash and approximately 0.61 of a
share of Adelphia Class A common stock and each outstanding share of Century
Class B common stock would be converted into approximately $11.81 in cash and
approximately 0.64 of a share of Adelphia Class A common stock. The amendment
did not change the aggregate merger consideration being paid by Adelphia for
the outstanding shares of Century common stock.

Adelphia's Reasons For The Merger

   The following sets forth Adelphia's principal reasons for the merger.

   The merger is consistent with Adelphia's growth strategy. Adelphia believes
that growth will allow it to continue to remain competitive in today's
telecommunications marketplace. The merger and other pending acquisitions are
the result of the implementation of this strategy.

   The Adelphia board believes that the merger presents a rare opportunity to
acquire, in a single transaction, sizable and attractive cable television
systems. The addition of these properties will enhance the ability of Adelphia
to compete in the telecommunications industry today and in the future.

   In particular, Century is a strong strategic fit with Adelphia. Century
provides Adelphia with a strong footprint in additional key markets that
overlay well with the markets addressed by Adelphia and Hyperion. This will
allow Adelphia and Hyperion to offer video, Internet and telephone services in
these new markets.

   In addition, the merger will allow Adelphia to continue to implement its
clustering strategy commenced many years ago. Along with the acquisitions of
FrontierVision, Harron and Telesat's interests in Olympus, the

                                       45
<PAGE>

merger will provide Adelphia with over 4.8 million basic subscribers, with over
90% of all basic subscribers residing in eleven clusters averaging over 400,000
basic subscribers. Adelphia will have premier clusters of basic subscribers
with favorable demographics in Los Angeles, south Florida, New England,
Ohio/Kentucky and western New York.

   The merger will significantly increase Adelphia's market capitalization
which should make Adelphia stock attractive to a new class of investors. If the
merger and other pending acquisitions are consummated, Adelphia will become the
sixth largest cable operator in the United States with a market capitalization
in excess of $7 billion. This should improve the liquidity and trading
characteristics of the Adelphia stock with the potential to translate into
better value recognition for Adelphia's stockholders, including former Century
stockholders who will receive Adelphia stock in the merger.

   Dr. Tow and John Rigas and the other Century and Adelphia senior management
have known each other for many years and share a similar management style and a
common vision for the industry and the combined companies. This should
facilitate the integration of the companies.

Information And Factors Considered By The Adelphia Board

   In connection with its approval of the merger and recommendation that
stockholders approve the Adelphia merger proposal, the Adelphia board
considered the following factors:

  .  the reasons described under "Adelphia's Reasons For The Merger;"

  .  the terms and conditions of the merger agreement and related agreements,
     including, among other things,

    -- the merger consideration, including the fact that fluctuations in
       the price of the Adelphia Class A common stock will affect the
       consideration to be received by holders of Century common stock in
       the merger,

    -- the agreement of certain stockholders of Century to vote in favor of
       the merger as described under "The Merger Agreement And Related
       Agreements--Related Agreements--The Class B Voting Agreement,"

    -- the limitations upon the interim business operations of Century
       pending the closing of the merger,

    -- the conditions to consummation of the merger, and

    -- the circumstances under which the merger agreement could be
       terminated, including the termination fees associated therewith;

  .  the familiarity of the Adelphia board with the business, properties and
     prospects of Century, including the opportunities and alternatives
     available to Adelphia if the merger is not undertaken;

  .  the business rationale for the merger, including the strategic fit
     between Adelphia and Century and the belief that the combination of
     Adelphia and Century has the potential to enhance stockholder value;

  .  the expected tax treatment of the merger for U.S. federal income tax
     purposes;

  .  the accounting treatment of the merger, including the goodwill that will
     be recorded on the financial statements of Adelphia;

  .  the presentations by Adelphia's management and Adelphia's financial,
     legal and other advisors regarding the merger;

  .  the opinion of Daniels to the effect that, as of March 5, 1999 and based
     upon and subject to certain matters stated in their opinion, the merger
     consideration was fair to Adelphia and its common stockholders from a
     financial point of view (a copy of the Daniels opinion, setting forth
     the

                                       46
<PAGE>

     assumptions made and limitations on the review undertaken in rendering
     such opinion, is attached as Appendix B to this joint proxy
     statement/prospectus and is described under "Opinion of Adelphia's
     Financial Advisor");

  .  the interests of the executive officers and directors of Century in the
     merger, including the matters described under "Interests Of Certain
     Persons In The Merger;" and

  .  the impact of the merger on the customers and employees of each of
     Adelphia and Century.

   The Adelphia board also considered the following potential adverse
consequences of the merger:

  .  the challenges and potential costs of combining the businesses of two
     major companies and the attendant risks of not achieving the expected
     operating efficiencies or improvements in earnings, and of diverting
     management focus and resources from other strategic opportunities and
     from operational matters for an extended period of time;

  .  the assumption of the Century debt and the potential need to refinance
     it; and

  .  the risk that the merger will not be consummated.

   The foregoing discussion of the information and factors considered by the
Adelphia board is not intended to be exhaustive but includes the material
factors that the board considered.

   In view of the wide variety of factors considered in connection with its
evaluation of the merger and the complexity of these matters, the Adelphia
board did not find it practicable to and did not attempt to quantify, rank or
otherwise assign relative weights to these factors. In addition, other than as
described above, the Adelphia board did not undertake to make any specific
determination as to whether any particular factor (or any aspect of any
particular factor) was favorable or unfavorable to Adelphia, but, rather,
conducted an overall analysis of the factors described above, including
thorough discussions with Adelphia's management and legal, financial and
accounting advisors. In considering the factors described above, individual
members of the Adelphia board may have given different weight to different
factors. The Adelphia board considered all these factors as a whole, and
overall considered the factors to be favorable to and to support its
determination.

Recommendation Of The Adelphia Board

   For the reasons discussed above, the Adelphia board has unanimously
approved the Adelphia merger proposal and recommends that Adelphia
stockholders vote "FOR" approval of the Adelphia merger proposal.

Century's Reasons For The Merger

   The following sets forth Century's principal reasons for the merger.

   As discussed above, in the last several years the cable television industry
has undergone significant changes due to technological advances, expanded
service offerings and a new regulatory structure. As a result of technological
advances and the reduction of regulatory barriers, the traditional services
provided by cable television operators have been expanding rapidly. In
addition, the cable television industry has been experiencing a period of
unprecedented consolidation in order to gain necessary critical mass and
increase the size of subscriber clusters.

   Century took various steps to try to meet the demands for new services and
counter increasing competitive pressures. Century refocused its business and
energies on its cable television business, selling its interests in Centennial
Cellular Corp., a wireless telephony company, and two Australian pay
television companies. To increase its customer base and increase its presence
in its key markets in southern California, since May 31, 1996 Century has made
several small acquisitions of cable systems serving an aggregate of
approximately 37,500 basic subscribers in California and entered into a
definitive agreement to establish a strategic partnership

                                      47
<PAGE>

with TCI. Under the terms of the partnership, TCI and Century each will
contribute to the partnership all of their assets related to the businesses of
certain cable television systems in southern California. Century will manage
the partnership's newly-combined cable systems, which will serve approximately
772,000 basic subscribers, and will own approximately 69.5% of the partnership.
In connection with the formation of the partnership, Century and TCI also
agreed to exchange certain cable television systems owned by Century in
northern California for certain cable systems owned by TCI in southern
California.

   Century also has undertaken various projects to expand the operations of
certain cable television systems into adjacent and previously unbuilt areas and
to rebuild and upgrade existing cable systems. Century also has been
considering the further upgrade of its cable television distribution systems in
certain markets to expand its capability for the delivery of enhanced video,
voice and data transmission.

   As Century implemented the steps described above, consolidation in the cable
industry accelerated as the largest cable system operators, major
telecommunications corporations and others concluded that cable television
networks offered an attractive opportunity to deploy advanced broadband
networks capable of delivering new voice and data services to large numbers of
consumers and that only the largest of cable operators would be able to obtain
critical mass in key markets and have access to the capital necessary to
compete effectively. In this environment of rapid consolidation and escalating
demands for capital expenditures needed to upgrade plant, Century became
increasingly concerned about its ability to grow and gain critical mass as an
independent company. As a result, as noted above in "Background Of The Merger,"
Century engaged DLJ as its financial advisor to explore its strategic
alternatives, including a sale of the Company.

   Adelphia was identified by DLJ and Century as one of the most likely
strategic buyers of Century, and DLJ sent a confidential memorandum describing
Century and its business to Adelphia as well as to other potential buyers who
executed a confidentiality agreement.

   Century viewed favorably the merger consideration offered by Adelphia,
particularly in comparison to the consideration received in various recent
comparable merger transactions as described under "Opinion Of Century's
Financial Advisor" and in comparison to the merger consideration offered by the
other bidders. The Century board also viewed as a positive the ability of the
Century stockholders to share in the future appreciation of the combined
companies.

   Century thus concluded that the merger with Adelphia offers Century's
stockholders an attractive premium for their shares, while enabling them to
participate in the future growth potential of the combined businesses of
Adelphia and Century. Century believes that the combination of the business of
Century with the business of Adelphia will result in a company that is better
able to compete in the changing telecommunications marketplace than either
company would be able to alone.

Information And Factors Considered By The Century Board

   In connection with its approval of the merger and its recommendation that
Century stockholders approve the merger, the Century board considered the
following information and factors:

  .  the factors described under "Background Of The Merger" and "Century's
     Reasons For The Merger;"

  .  the consideration to be received by the holders of the Century common
     stock in the merger, including the premium to be received by the holders
     of the Century Class B common stock and the voting control and majority
     position of the holders of the Century Class B common stock, and the
     relationship of that consideration to the consideration received in
     various comparable merger transactions;

  .  the opportunities and alternatives available to Century if the merger
     with Adelphia were not to be undertaken, including the proposals of the
     other bidders as well as the possibility of remaining independent;

                                       48
<PAGE>

  .  the business rationale for the merger, including the strategic fit
     between Century and Adelphia, the anticipated impact of the proposed
     transaction on the combined company's future performance and the Century
     board's belief that the combination of Century and Adelphia has the
     potential to enhance the value of the Adelphia common stock to be
     received by Century stockholders in the merger;

  .  Century's familiarity with, and its evaluation of, the business,
     properties and prospects of Adelphia;

  .  the terms and conditions of the merger agreement and related agreements,
     including

    -- the representations, warranties and covenants of Century and
       Adelphia in the merger agreement,

    -- the conditions to consummation of the merger,

    -- the circumstances under which the merger agreement could be
       terminated, and

    -- the agreements of the controlling stockholders of both Century and
       Adelphia to vote in favor of the merger;

  .  historical information regarding Century's and Adelphia's businesses,
     financial performance and condition, operations, technologies,
     managements and competitive positions;

  .  current financial market conditions and historical market prices,
     volatility and trading information with respect to the Century common
     stock and the Adelphia common stock;

  .  the detailed financial analyses and pro forma and other information
     relating to the two companies presented by DLJ;

  .  the opinion of DLJ to the effect that, as of March 5, 1999 and based
     upon and subject to certain matters stated in their opinion, the merger
     consideration to be received by the holders of Century's Class A common
     stock (other than holders who are affiliates of Century) pursuant to the
     merger agreement was fair to such holders from a financial point of view
     (a copy of the DLJ opinion, setting forth the assumptions made and
     limitations on the review undertaken in rendering such opinion, is
     attached as Appendix C to this joint proxy statement/prospectus and is
     described under "Opinion Of Century's Financial Advisor");

  .  the fact that fluctuations in the price of the Adelphia Class A common
     stock will affect the value of the consideration to be received by
     holders of Century common stock in the merger;

  .  the impact of the merger on the respective customers and employees of
     Century and Adelphia;

  .  the interests of the executive officers and directors of Century in the
     merger, including the matters described under "Interests of Certain
     Persons In The Merger;" and

  .  the expected tax treatment of the merger for U.S. federal income tax
     purposes.

   The Century board also considered the following potential adverse
consequences of the merger:

  .  the risk that the merger may not be consummated, including the
     termination fee that might be payable by Century upon a termination of
     the merger agreement;

  .  the effect of the public announcement of the merger on Century's sales,
     operating results and stock price and its ability to attract and retain
     key management, sales and marketing and technical personnel;

  .  the risk that the potential benefits sought in the merger might not be
     fully realized;

  .  the possibility of substantial charges to be incurred in connection with
     the merger, including costs of integrating the businesses and
     transaction expenses arising from the merger; and

  .  the risk that despite the efforts of the combined company, key technical
     and management personnel might not remain employed by the combined
     company.

                                       49

   The foregoing discussion of the information and factors considered by the
Century board is not intended to be exhaustive but includes the material
factors that the board considered.

   In view of the wide variety of factors considered in connection with its
evaluation of the merger and the complexity of these matters, the Century board
did not find it practicable to and did not attempt to quantify, rank or

advisors. In considering the factors described above, individual members of the
Century board may have given different weight to different factors. The Century
board considered all these factors as a whole and considered the factors in
their entirety to be favorable to and to support its determination.

Recommendation Of The Century Board

   For the reasons discussed above, the Century board has unanimously approved
and deemed advisable the Century merger proposal and recommends that Century
stockholders vote "FOR" approval of the Century merger proposal.

Opinion Of Adelphia's Financial Advisor

   Daniels has acted as financial advisor to Adelphia in connection with the
merger. Daniels was selected by Adelphia based on Daniels' experience,
expertise and familiarity with Adelphia and its business in particular, as well
as with the cable and communications industries in general. Daniels is a
leading media and communications investment banking firm and is regularly
engaged in the valuation of businesses and securities in connection with
mergers and acquisitions, leveraged buyouts, competitive biddings, private
placements and valuations for corporate and other purposes. In addition to
acting as Adelphia's financial advisor in connection with the merger, Daniels
has provided certain investment banking and brokerage services to Adelphia from
time to time, including in connection with its pending acquisition of
FrontierVision.

   In connection with Daniels engagement, Adelphia requested that Daniels
evaluate the fairness of the value to be paid by Adelphia in the merger from a
financial point of view. On March 4, 1999, Daniels rendered to the Adelphia
board its oral opinion (which was subsequently confirmed in a written opinion
dated March 5, 1999) that, as of such date, and based upon and subject to
certain matters stated in such opinion, the merger value was fair to Adelphia
from a financial point of view.

   The full text of Daniels' written opinion to the Adelphia board dated March
5, 1999, which sets forth the procedures followed, assumptions made, matters
considered and limitations on the review undertaken in rendering such opinion,
is attached as Appendix B to this joint proxy statement/prospectus and is
incorporated herein by reference. Stockholders are urged to read this opinion
carefully and in its entirety. Daniels' opinion is directed to the Adelphia
board and relates only to the fairness of the merger from a financial point of
view to Adelphia and its common stockholders. It does not address any other
aspect of the merger or any related transaction and does not constitute a
recommendation to any stockholder as to how such stockholder should vote at the
Adelphia special meeting. The summary of the opinion of Daniels set forth in
this joint proxy statement/prospectus is qualified in its entirety by reference
to the full text of the opinion.

   In arriving at its opinion, Daniels reviewed the merger agreement and
certain publicly available business and financial information relating to
Adelphia and Century. Daniels also reviewed certain other information relating
to Adelphia and Century, including financial forecasts, provided to or
otherwise discussed with Daniels by Adelphia and Century, and met with the
management of both Adelphia and Century to discuss the businesses and prospects
of Adelphia and Century. Daniels also considered certain financial and stock
market data of Adelphia and Century, and compared those data with similar data
for other publicly held companies in

                                       50
<PAGE>

businesses similar to Adelphia and Century, and considered, to the extent
publicly available, the financial terms of certain other business combinations
and other transactions recently effected. Daniels also considered such other
information, financial studies, analyses and investigations and financial,
economic and market criteria that Daniels deemed relevant.

   In connection with its review, Daniels did not assume any responsibility for
independent verification of any of the foregoing information and relied on such
information being complete and accurate in all material respects. With respect
to the financial forecasts, Daniels assumed that such forecasts were reasonably
prepared on bases reflecting the best currently available estimates and
judgments of the management of Adelphia and Century as to the future financial
performance of Adelphia and Century and the potential strategic benefits and
synergies (including the amount, timing and achievability thereof) anticipated
to result from the merger. Daniels was not requested to make, and did not make,
an independent evaluation or appraisal of the assets or liabilities (contingent
or otherwise) of Adelphia or Century, nor was Daniels furnished with any such
evaluation or appraisals. In addition, Daniels' opinion was necessarily based
upon information available to, and financial, economic, market and other
conditions as they existed and could be evaluated by, Daniels on the date of
its opinion. Daniels did not express any opinion as to the actual value of
Adelphia Class A common stock pursuant to the merger or the prices at which
such securities will trade subsequent to the merger. Although Daniels evaluated
the merger from a financial point of view to Adelphia, Daniels was not
requested to, and did not recommend, the specific consideration payable in the
merger, which consideration was determined through negotiations between
Adelphia and Century. No other limitations were imposed by Adelphia on Daniels
with respect to the investigations made or procedures followed by Daniels in
rendering its opinion.

   In preparing its opinion to the Adelphia board, Daniels performed a variety
of financial and comparative analyses, including those described below. The
summary below describes the material analyses performed by Daniels but does not
purport to be a complete description of the analyses underlying the opinion of
Daniels. The preparation of a fairness opinion is a complex analytic process
involving various determinations as to the most appropriate and relevant
methods of financial analyses and the application of those methods to the
particular circumstances and, therefore, such an opinion is not readily
susceptible to partial analysis or summary description. In arriving at its
opinion, Daniels made qualitative judgments as to the significance and
relevance of each analysis and factor considered. Accordingly, Daniels believes
that its analyses must be considered as a whole and that selecting portions of
such analyses and factors, without considering all analyses and factors, could
create a misleading or incomplete view of the processes underlying such
analyses and opinions. In its analyses, Daniels made numerous assumptions with
respect to Adelphia, Century, industry performance, regulatory, general
business, economic, market and financial conditions, and other matters, many of
which are beyond the control of Adelphia and Century. No company, transaction
or business used in such analyses as a comparison is identical to Adelphia,
Century or the merger, nor is an evaluation of the results of such analyses
entirely mathematical; rather, such analyses involve complex consideration and
judgments concerning financial and operating characteristics and other factors
that could affect the acquisition, public trading or other values of the
companies, business segments or transactions being analyzed. The estimates
contained in such analyses and the ranges of valuations resulting from any
particular analyses are not necessarily indicative of actual values or
predictive of future results or values, which may be significantly more or less
favorable than those suggested by such analyses. In addition, analyses relating
to the value of businesses or securities do not purport to be appraisals or to
reflect the prices at which businesses or securities actually may be sold.
Accordingly, such analyses and estimates are inherently subject to substantial
uncertainty. The opinion and financial analysis of Daniels was only one of many
factors considered by the Adelphia board in its evaluation of the merger and
should not be viewed as determinative of the views of the Adelphia board or
Adelphia's management with respect to the merger.

   The following is a summary of the material financial analyses reviewed by
Daniels in their presentation to the Adelphia board with regard to its oral
opinion on March 4, 1999.

   Selected Companies Analysis. Comparable company analysis is used to compare
a company's performance relative to comparable publicly-traded peers. Daniels
reviewed selected financial and operating

                                       51
<PAGE>

results for several public cable companies that were deemed to have similar
characteristics to Adelphia and Century. However, because of the inherent
differences in size, focus and characteristics of Adelphia and Century and the
selected comparable companies, Daniels used its own qualitative judgment
concerning these differences in order to obtain a comparable measure of public
market valuation. Daniels compared certain financial, market and operating
information of Adelphia and Century with corresponding data of the following
selected publicly traded companies in the cable industry: Cox Communications,
Inc., Comcast Corporation, MediaOne Group Inc., Cablevision Systems Corporation
and TCA Cable, Inc. (together, the "Selected Companies"). Daniels calculated
adjusted market values (equity market value plus total debt, preferred stock
and minority interests, less cash and cash equivalents and the estimated value
of the non-consolidated cable and the non-cable assets) as multiples of
estimated calendar 1998, 1999 and 2000 cable-only earnings before interest,
taxes, depreciation and amortization ("EBITDA"), based on publicly available
research analyst estimates. The range of cable-only EBITDA multiples for the
Selected Companies in calendar 1998 was 15.7 to 23.9, compared with 16.8 for
Century (at the merger valuation as of March 4, 1999), and in calendar 1999 was
14.0 to 19.6, compared with 14.3 for Century (at the merger valuation as of
March 4, 1999).

   Selected Transactions Analysis. Using publicly available information,
Daniels performed an analysis of financial statistics, including estimates of
EBITDA multiples and prices paid per subscriber in comparable sale or merger
situations. As no company utilized in this analysis was identical to Century
and because of the variability and related significance of different business
lines outside of the core cable business, Daniels focused its analysis of
comparable transactions on the estimates of valuation attributable to the cable
business only. Daniels reviewed the implied transaction multiples paid in the
following recent or pending selected merger and acquisition transactions in the
cable industry (acquiror/target): Cox/Prime South Diversified, Inc., Vulcan
Ventures, Inc./Marcus Cable Company LLC, Vulcan Ventures, Inc./InterMedia
Partners I and IV, TCI/InterMedia Partners IV, Comcast Corporation/Prime Cable,
Adelphia Communications Corporation/FrontierVision, Charter
Communications/Interlink/Rifkin Acquisition Partners, Comcast
Corporation/Greater Media, Charter Communications/Greater Media and Charter
Communications/Renaissance Media (the "Selected Transactions"). Daniels
calculated adjusted transaction values, the amount paid in the transaction for
the equity of the target, plus total debt, preferred stock and minority
interests, less cash and cash equivalents and the estimated value of the non-
consolidated cable and the non-cable assets (the "Transaction Value"), in the
Selected Transactions:

  .  as a multiple of the then estimated current-year cable-only EBITDA; and

  .  on a per subscriber basis.

   The Transaction Values of the Selected Transactions ranged from 12.5 to 16.0
current-year cable-only EBITDA and from $2,588 to $3,653 per subscriber.
Daniels calculated that the Transaction Value for the merger was 14.3 estimated
calendar 1999 EBITDA as estimated by Century management and Adelphia
management. The Transaction Value for the merger was $3,600 per estimated 1999
subscriber (consolidated and non-consolidated).

   No transaction utilized in this comparable transaction analysis is identical
to the merger and the amount of information available with respect to these
transactions varies widely. In evaluating these transactions, Daniels made
judgments and assumptions with regard to industry performance, general
business, economic, market and financial conditions and other matters in
general. Accordingly, an analysis of the results of this review is not strictly
a mathematical exercise.

   Discounted Cash Flow Analysis for Century. Daniels estimated the present
value of the future stand-alone, unlevered free cash flows that could be
produced by Century, based on internal estimates of the management of Century
as adjusted based on discussions with the management of Century. Based on this
analysis, the net present value of Century ranged from approximately $5.8
billion to $6.2 billion. This compares with the value for Century in the merger
of approximately $5.7 billion, based on the closing price of Adelphia Class A
common stock on March 4, 1999.

                                       52
<PAGE>

   Certain Other Factors and Comparative Analyses. In its presentation to the
Adelphia board, Daniels reviewed certain other factors and other comparative
analyses, including, among other things, (a) the historical stock price
performance of Adelphia, Century, the S&P 500, and indexes composed of selected
companies in the cable industries, (b) the premium paid by Adelphia for Century
Class A common stock and Century Class B common stock in relation to the public
trading prices of Century Class A common stock prior to announcement of the
merger in comparison to historical averages for other merger and acquisition
transactions, (c) the premium paid by Adelphia for Century Class A common stock
in relation to Century Class B common stock in comparison to other selected
merger and acquisition transactions, and (d) the implied total debt and
preferred stock leverage of Adelphia prior to and pro forma for the merger.

   Under the terms of their engagement, Adelphia has agreed to pay Daniels for
its advisory services in connection with the merger an aggregate fee of $3
million. For the opinion, and included in the aggregate fee, Adelphia has
agreed to pay Daniels $1 million, of which $500,000 became payable upon
execution of the engagement agreement and $500,000 will be payable upon
closing. The remaining $2 million of the aggregate fee is also payable upon
closing. Adelphia also has agreed to reimburse Daniels for reasonable out-of-
pocket expenses incurred by Daniels in performing its services, and to
indemnify Daniels against certain liabilities, including liabilities under the
U.S. federal securities laws arising out of this engagement.

   Daniels has in the past provided various financial services to Adelphia, and
brokerage services to Adelphia, Century and certain of their respective
affiliates, in each case unrelated to the merger, for which services Daniels
has received compensation.

Opinion Of Century's Financial Advisor

   In its role as financial advisor to Century, DLJ was asked by Century to
render an opinion to the Century board as to the fairness to the holders of
Century Class A common stock (other than stockholders who are affiliates of
Century), from a financial point of view, of the merger consideration (as
contemplated by the merger agreement as of such date) to be received by such
holders for their shares of Century Class A common stock. DLJ was not asked to
consider, and it did not consider, the fairness of the merger consideration to
holders of Century Class A common stock who are affiliates of Century. On March
4, 1999, DLJ delivered to the Century board its oral opinion, which oral
opinion was confirmed in writing in the DLJ opinion, that, as of such date, and
based on and subject to the assumptions, limitations and qualifications as set
forth in such opinion, the merger consideration to be received by holders of
the Century Class A common stock (other than stockholders who are affiliates of
Century), was fair to such holders from a financial point of view.

   The full text of the DLJ opinion is attached as Appendix C to this joint
proxy statement/prospectus. The summary of the DLJ opinion set forth in this
joint proxy statement/prospectus is qualified in its entirety by reference to
the full text of the DLJ opinion. Holders of the Century Class A common stock
are urged to read the DLJ opinion carefully and in its entirety for the
procedures followed, assumptions made, other matters considered and limits of
the review by DLJ in connection with such opinion.

   The DLJ opinion was prepared for the Century board and was directed only to
the fairness from a financial point of view, as of the date thereof, to the
holders of the Class A common stock (other than stockholders who are affiliates
of Century) of the merger consideration to be received by such holders. The DLJ
opinion does not address the relative merits of the merger or of any other
business strategies being considered by the Century board, nor does it address
the Century board's decision to proceed with the merger. The DLJ opinion does
not constitute a recommendation to any stockholder as to how such stockholder
should vote on the merger. DLJ expressed no opinion in the DLJ opinion as to
the prices at which Adelphia Class A common stock will actually trade at any
time.

   Century selected DLJ as its financial advisor because it is an
internationally recognized investment banking firm that has substantial
experience in the media and communications industries and is familiar with
Century and its businesses. DLJ was not retained as an advisor to or agent of
the stockholders of Century or

                                       53
<PAGE>

any other person. The type and amount of consideration in the merger was
determined in arm's-length negotiations between Century and Adelphia, as part
of an auction process. As part of its investment banking business, DLJ is
regularly engaged in the valuation of businesses and securities in connection
with mergers, acquisitions, underwritings, sales and distributions of listed
and unlisted securities, private placements and valuations for corporate and
other purposes.

   In arriving at the DLJ opinion, DLJ reviewed a draft dated March 4, 1999 of
the merger agreement and the schedules thereto and reviewed financial and other
information that was publicly available or furnished to DLJ by Century and
Adelphia, including information provided during discussions with management of
Century and Adelphia. Included in the information provided to DLJ by Century
were certain financial and operations forecasts for the fiscal periods ending
May 31, 1999 and May 31, 2000. In addition, DLJ compared certain financial and
securities data of Century and Adelphia with various other companies whose
securities are traded in public markets, reviewed the historical stock prices
and trading volumes of Century Class A common stock and Adelphia Class A common
stock, reviewed prices and premiums paid in certain other business
combinations, and conducted such other financial studies, analyses and
investigations as DLJ deemed appropriate for purposes of rendering the DLJ
opinion.

   In rendering the DLJ opinion, DLJ relied upon and assumed the accuracy,
completeness and fairness of all the financial and other information that was
available to DLJ from public sources, that was provided to DLJ by Century,
Adelphia or their respective representatives, or that was otherwise reviewed by
DLJ. With respect to the financial analyses and forecasts supplied to DLJ by
Century, DLJ assumed that they were reasonably prepared on a basis reflecting
reasonable estimates and judgments of the management of Century. The DLJ
opinion states that as Century is aware, Adelphia did not make available to DLJ
Adelphia's projections of expected future performance. DLJ assumed that no
requisite regulatory consent or approval for the merger will impose any
condition, including any divestiture requirement, that will have a material
adverse effect on the contemplated benefits of the merger. DLJ did not assume
any responsibility for making an independent evaluation of Century's or
Adelphia's assets or liabilities or for making any independent verification of
any of the information reviewed by DLJ. DLJ relied as to certain legal matters
relating to the merger agreement and transactions contemplated thereby on
advice of counsel to Century.

   The DLJ opinion is necessarily based on economic, market, financial and
other conditions as they exist on, and on the information made available to DLJ
as of, the date thereof. The DLJ opinion states that, although subsequent
developments may affect the DLJ opinion, DLJ does not have any obligation to
update, revise or reaffirm its opinion.

   The following is a summary of the material analyses which DLJ presented to
the Century board at two board meetings on March 4, 1999 in connection with the
rendering of the DLJ opinion. Prior to reviewing such analyses, DLJ reviewed
with the Century board the results of efforts by Century and its advisors to
solicit indications of interest and proposals from third parties with respect
to a purchase of Century.

   Valuation Multiples Analysis. Using financial forecasts provided by Century,
DLJ analyzed the enterprise value (as defined below) of Century, based on the
merger consideration for the Century Class A common stock and the Century Class
B common stock, as a multiple of Century's estimated fiscal 1999 and 2000
EBITDA and EBITDA before corporate overhead ("System Cash Flow") as well as the
estimated calendar year 1999 EBITDA and System Cash Flow, each on a pro rata
basis to reflect Century's less than wholly owned interest in certain of its
cable operations. The estimated calendar year 1999 EBITDA and System Cash Flow
were derived by DLJ based on the fiscal 1999 and 2000 forecasts provided by
Century. Based on these assumptions, DLJ calculated an enterprise value of
approximately $4.6 billion using the blended price per share of $46.47 to be
received by holders of the Century Class A common stock and the Century Class B
common stock, based on the closing price of $57.375 per share of Adelphia Class
A common stock on March 3, 1999. Enterprise value is defined as the value of
fully-diluted common equity plus long-term debt and

                                       54
<PAGE>

preferred stock, if any, minus cash, the proceeds, if any, from the exercise of
outstanding options and warrants and the value of certain other assets and
investments. Where appropriate, enterprise value is adjusted on a pro rata
basis to reflect less than wholly owned operations and on a pro forma basis to
reflect pending acquisitions, divestitures, joint ventures or other
transactions. In particular, for purposes of this analysis, Century's
enterprise value, EBITDA, System Cash Flow and basic subscribers have been
adjusted on a pro forma basis to reflect Century's estimated pro rata share of
its interests in the pending joint venture with TCI. DLJ's analysis of
enterprise value as a multiple of each of fiscal 2000 estimated System Cash
Flow and fiscal 2000 estimated EBITDA yielded multiples of 14.8x and 16.5x,
respectively, before the impact of any synergies to be realized by the combined
company following the merger.

   DLJ then performed a sensitivity analysis of the valuation multiples using
enterprise values based on assumed share prices received for Century Class A
common stock and Century Class B common stock ranging from $40.00 per share to
$48.00 per share. DLJ's analysis of enterprise value as a multiple of each of
fiscal 2000 estimated System Cash Flow and fiscal 2000 estimated EBITDA yielded
a range of multiples of 13.2x to 15.2x and 14.7x to 16.9x, respectively.
Enterprise value per cable system subscriber ranged from $3,259 to $3,751.

   Historical Stock Price Analysis. DLJ performed a comparative historical
analysis of indexed closing prices for the period from March 3, 1997 to March
3, 1999 for Century, Adelphia, the S&P 400 index and a comparable company index
(the "Cable Composite Index"), which included Comcast Corporation, Cox
Communications Inc., Cablevision Systems Corporation, Jones Intercable Inc.,
TCA Cable TV Inc., TCI and MediaOne Group, Inc. (the "Comparable Cable
Companies"). Since March 3, 1997, the Century Class A common stock reached a
high of $36.25 per share and a low of $9.63 per share. On March 3, 1999, the
closing price of Century Class A common stock was $35.25. Since March 3, 1997,
the Cable Composite Index has outperformed the S&P 400 index.

   DLJ also performed a comparative historical analysis of Adelphia's closing
prices for the period from March 3, 1997 to March 3, 1999 and of the S&P 400
index relative to the Cable Composite Index. Since March 3, 1997, the Adelphia
Class A common stock reached a high of $62.13 per share and a low of $5.00 per
share. On March 3, 1999, the closing price of Adelphia Class A common stock was
$57.375.

   This analysis also indicated that both of the Adelphia Class A common stock
and the Century Class A common stock outperformed the Cable Composite Index
during the period from March 3, 1997 to March 3, 1999.

   Cable Industry Performance. DLJ's analysis of cable industry performance
consisted of a historical analysis of the respective enterprise values of
companies, based on recent stock prices, consisting of the Comparable Cable
Companies and Adelphia (collectively, the "Cable Industry Companies") as a
multiple of their respective forward EBITDA for each of December 31, 1996,
December 31, 1997, December 31, 1998 and March 3, 1999. Forward EBITDA refers
to EBITDA obtained from research analyst reports for the calendar year
following the current calendar year. The analysis indicated that the enterprise
value for the respective Cable Industry Companies, as a multiple of their
respective forward EBITDA, more than doubled over the past two years.

   The following table sets forth the ranges, average and median of the
enterprise values as a multiple of forward EBITDA for the Cable Industry
Companies:

   Public Comparables Analysis. DLJ analyzed selected historical and projected
operating information, stock market data and financial ratios for the
Comparable Cable Companies.

   DLJ compared the enterprise value of each of the Comparable Cable Companies
to certain selected financial data. In examining these Comparable Cable
Companies, DLJ analyzed the enterprise value, based on recent stock prices, of
the companies as a multiple of each company's respective calendar year 1999
estimated EBITDA and calendar year 2000 estimated EBITDA and the enterprise
value per cable system subscriber. DLJ compared the foregoing data of the
Comparable Cable Companies to similar data for Century and Adelphia based on
their respective closing prices for Class A common stock on March 3, 1999.
Calendar year 1999 estimated EBITDA and calendar year 2000 estimated EBITDA
were obtained from research analyst reports. The following table summarizes
DLJ's analysis:

   DLJ then calculated implied per share values of Century Class A common stock
by applying Century's calendar year 1999 and 2000 estimated EBITDA to the high,
median, average and low multiples derived from its analysis of the Comparable
Cable Companies. For purposes of the DLJ analyses, the per share values of
Century Class A common stock were calculated based on the outstanding shares of
Century Class A common stock, as of February 11, 1999, on a fully diluted
basis. Century's calendar year 1999 and 2000 EBITDA were derived by DLJ based
on the fiscal 1999 and 2000 forecasts provided by Century. DLJ calculated the
ranges, median and average of implied per share values of Century Class A
common stock as follows:

   M&A Comparables Analysis. DLJ reviewed 24 selected acquisitions or proposed
acquisitions involving cable systems companies (collectively, the "M&A
Comparable Companies"). In examining these acquisitions, DLJ calculated the
enterprise value of the acquired company in each of these transactions as a
multiple of forward EBITDA and per cable system subscriber. Forward EBITDA for
purposes of this analysis refers to the fiscal or calendar year following the
fiscal or calendar year in which an announcement of an acquisition was

                                       56

made as obtained by DLJ from various publicly available sources. DLJ's analysis
of enterprise values as a multiple of forward EBITDA and per cable system
subscriber of the M&A Comparable Companies yielded the following:

   Comparable Premiums Paid Analysis. DLJ determined the implied premium over
the common stock trading prices for one day, one week and four weeks prior to
the announcement date of acquisitions announced since January 1, 1995 with a
transaction value from $3.0 billion to $5.0 billion based on information
obtained from the Securities Data Corporation. The following table sets forth

   Pro Forma Valuation Sensitivity Analysis. DLJ performed a pro forma implied
per share valuation analysis of the Adelphia Class A common stock using
Adelphia's calendar year 1999 estimated EBITDA after giving effect to the
proposed merger with Century and based upon multiples ranging from 11.0x to
16.0x. This analysis yielded pro forma implied per share values for the
Adelphia Class A common stock ranging from $32.90 to $64.23. Based on these
values of shares of Adelphia Class A common stock and the cash consideration to
be received by holders of the Century Class A common stock, this analysis yield
implied per share values of the Century Class A common stock ranging from
$29.31 to $48.49.

   The summary set forth above does not purport to be a complete description of
the analyses performed by DLJ but describes, in summary form, the material
elements of the presentations made by DLJ to the Century board on March 4,
1999. The preparation of a fairness opinion involves various determinations as
to the most appropriate and relevant methods of financial analysis and the
application of these methods to the particular circumstances and, therefore,
such an opinion is not readily susceptible to summary description. Each of the
analyses conducted by DLJ was carried out in order to provide a different
perspective on the merger and to add to the total mix of information available.
DLJ did not form a conclusion as to whether any individual analysis, considered
in isolation, supported or failed to support an opinion as to fairness from a
financial point of view. Rather, in reaching its conclusions, DLJ considered
the results of the analyses in light of each other and ultimately reached each
opinion based on the results of all analyses undertaken in connection with such
opinion taken together as a whole. DLJ did not place particular reliance or
weight on any individual analysis, but instead concluded that its analyses,
taken as a whole, supported its determination. Accordingly, notwithstanding the
separate factors summarized above, DLJ has indicated to Century that, with
respect to the DLJ opinion, it believes that its analyses must be considered as
a whole and that selecting portions of its analyses and the factors considered
by it, without considering all analyses and factors, could create an incomplete
view of the evaluation process underlying its opinion. The analyses performed
by DLJ are not necessarily indicative of actual values or future results, which
may be significantly more or less favorable than suggested by such analyses.

   Pursuant to the terms of an engagement agreement dated December 16, 1998,
Century agreed to pay (a) a retainer fee of $100,000, payable upon the
execution of the DLJ engagement letter; (b) a fairness opinion fee of $2.5
million, of which $1.5 million was payable at the time DLJ notified the Century
board that it was prepared to deliver the DLJ opinion (irrespective of the
conclusion reached therein) and $1 million was payable upon the earlier to
occur of (x) delivery of the update of the DLJ opinion, in connection with
obtaining stockholder approval of the merger, and (y) mailing to stockholders
of Century of this joint proxy statement/prospectus; and (c) a transaction fee
equal to (1) 0.30% of the total transaction value (as defined below) of Century
from $3,775 million to $3,850 million; (2) 0.35% of the total transaction value
of Century from $3,850 million to $3,925 million; (3) 0.40% of the total
transaction value of Century from $3,925 million to $4,010 million; and (4)
0.50% of $4,010 million in the case of the total transaction value of Century
in excess of $4,010 million, plus 5.0% of the total transaction value in excess
of $4,010 million, less the DLJ retainer fee and the fairness opinion fee
described above. Under the DLJ engagement letter, DLJ is not entitled to
receive a transaction fee if the total transaction value of Century does not
equal or exceed $3,775 million. For purposes of the DLJ engagement letter,
transaction value is defined as the aggregate value of outstanding common stock
of Century (treating any shares issuable upon exercise of options, warrants or
other rights of conversion as outstanding),

                                       58
<PAGE>

plus the amount of any debt assumed, acquired, remaining outstanding, retired
or defeased or preferred stock redeemed or remaining outstanding in connection
with the merger, less the value of cash and cash equivalents of Century, upon
consummation of the merger.

   In addition, Century agreed to reimburse DLJ, upon request by DLJ from time
to time, for all out-of-pocket expenses (including the reasonable fees and
expenses of counsel) incurred by DLJ in connection with its engagement, and to
indemnify DLJ and certain related persons against certain liabilities in
connection with the engagement, including liabilities under U.S. federal
securities laws. DLJ and Century management negotiated the terms of the fee
arrangement, and the Century board was aware of such arrangement, including the
fact that a significant portion of the aggregate fee payable to DLJ is
contingent upon consummation of the merger.

   In the ordinary course of business, DLJ and its affiliates may own or
actively trade the securities of Century and Adelphia for their own accounts
and for the accounts of their customers and, accordingly, may at any time hold
a long or short position in Century or Adelphia securities. DLJ has performed
investment banking and other services in the past for Century and has been
compensated for such services. Specifically, DLJ acted as Century's financial
advisor in connection with the merger of Centennial Cellular Corp., a
subsidiary of Century, with CCW Acquisition Corporation for which DLJ received
usual and customary fees. DLJ has also performed investment banking and other
services for Adelphia in the past and has been compensated for such services.

Accounting Treatment

   The merger will be accounted for under the purchase method of accounting,
with Adelphia treated as the acquirer. As a result, Adelphia will record the
assets and liabilities of Century at their estimated fair values and will
record as goodwill the excess of the purchase price over such estimated fair
values. The operating results of Century will be combined with the results of
Adelphia from the date of the merger. As a result, Adelphia's earnings for 1999
will not include Century's 1999 earnings prior to the merger. See "Unaudited
Pro Forma Condensed Consolidated Financial Information" for a description of
the adjustments expected to be recorded to Adelphia's financial statements.

Ownership Of Shares After The Merger

   After giving effect to the merger, the Citizens acquisition, the
FrontierVision acquisition discussed on page 9, the pending Highland Holdings
purchase of Adelphia Class B common stock discussed on page 9 and the
conversion of Adelphia's Series C cumulative convertible preferred stock and
Series D convertible preferred stock into shares of Adelphia Class A common
stock, the former holders of Century Class A common stock and Century Class B
common stock will hold approximately 39.7% of the outstanding Adelphia Class A
common stock. This will represent approximately 16.6% of the total voting power
of all outstanding Adelphia shares. The above percentages are as of August 6,
1999, and are based on approximately 122,500,000 shares of Adelphia Class A
common stock and 17,006,300 shares of Adelphia Class B common stock outstanding
as of that date after giving effect to the transactions described above and
assume that all Century stock options will be exercised prior to the merger.

Interests Of Certain Persons In The Merger

   Members of Century's management and the Century board have certain interests
in the merger that may be different from, or in addition to, the interests of
Century stockholders generally. Some of them have such interests in their
capacities as record or beneficial owners of, or holders of the power to vote,
shares of Century Class B common stock. The holders of the Century Class B
common stock are Dr. Tow, who is the Chairman and Chief Executive Officer of
Century, and two trusts established by Dr. Tow and Claire Tow, who is a
director of Century and the spouse of Dr. Tow. David Rosensweig, who is a
director and the Secretary of Century, is the sole trustee of one of these
trusts. The trustees of the other trust are Dr. Tow, Claire Tow and Mr.
Rosensweig. The Century board was aware of all of these interests and
considered them, among other matters, in approving the merger agreement and the
merger. These interests are described below.

                                       59
<PAGE>

 Adelphia Board

   The merger agreement provides that, from and after the effective time of the
merger, so long as the current Century Class B stockholders and their permitted
assignees and transferees (as defined in the merger agreement) own at least 10%
of the outstanding Class A common stock of Adelphia, they will be entitled to
nominate up to three members to Adelphia's board.

 Control Premium to Class B Stockholders

   The merger agreement provides that each share of Century Class A common
stock will, at the election of each holder but subject to proration as
described on pages 71-72, be converted into the right to receive $44.14 in
cash, 0.77269147 of a share of Adelphia Class A common stock or a combination
of cash and stock, whereas each share of Century Class B common stock will be
converted into approximately $48.14 in cash, 0.84271335 of a share of Adelphia
Class A common stock or a combination of cash and stock. The difference in the
consideration to be received by the holders of the Century Class A common stock
and the holders of the Century Class B common stock constitutes approximately a
9% premium, (assuming receipt of the cash consideration), payable to the
holders of Century Class B common stock. The outstanding shares of Century
Class B common stock have approximately 93% of the total combined voting power
of the outstanding Century Class A common stock and the outstanding Century
Class B common stock and represent a majority (approximately 54%) of the total
number of outstanding shares of Century Class A common stock and Century Class
B common stock. This gives the holders of the Century Class B common stock the
power to elect all but one member of the Century board. It also gives them the
power to control the vote on all other matters submitted to a vote of Century's
stockholders, except where separate class votes by the holders of the Century
Class A common stock and the Century Class B common stock are required by law
(as in the case of the merger with Adelphia). The Century board considered the
premium payable to the holders of the Century Class B common stock in
connection with its decision to approve the merger agreement and determined
that such premium was an acceptable control premium to such holders.

 Adelphia Stock Ownership After the Merger

   After giving effect to the merger, the Citizens acquisition, the
FrontierVision acquisition, the pending Highland Holdings purchase of Adelphia
Class B common stock and the conversion of Adelphia's Series C cumulative
convertible preferred stock and Series D convertible preferred stock into
shares of Adelphia Class A common stock, Dr. Tow and Claire Tow will
beneficially own approximately 27,244,000 shares of Adelphia Class A common
stock, representing approximately 22.2% of the outstanding Adelphia Class A
common stock and approximately 9.3% of the voting power of all outstanding
Adelphia common stock. Dr. Tow and Claire Tow each disclaim beneficial
ownership of some of these shares. After giving effect to the above
transactions, the directors and executive officers of Century (including Dr.
Tow and Claire Tow) will beneficially own in the aggregate 28,162,000 shares of
Adelphia Class A common stock, representing approximately 23% of the
outstanding Adelphia Class A common stock and approximately 9.6% of the voting
power of all outstanding Adelphia common stock assuming that all of the shares
of Century Class A common stock that they hold will be converted into Adelphia
Class A common stock subject to the proration procedures described below. These
percentages are based on share ownership of Century's directors and executive
officers as of August 6, 1999 and on approximately 122,500,000 shares of
Adelphia Class A common stock outstanding as of that date after giving effect
to the above transactions. These percentages assume that Dr. Tow, Claire Tow
and the directors and executive officers will receive Adelphia Class A common
stock for 79.24% of the shares of Century Class A common stock beneficially
owned by them and cash for 20.76% of the shares of Century Class A common stock
beneficially owned by them. These percentages also assume that all Century
stock options will be exercised prior to the merger.

 Century Options

   As of August 6, 1999, the directors and executive officers of Century held
options to purchase an aggregate of 179,100 shares of Century Class A common
stock that vest over time and will not yet be

                                       60
<PAGE>

exercisable as of the effective time of the merger. Under the merger agreement,
however, each option to purchase shares of Century Class A common stock will
become fully vested and exercisable at the effective time of the merger. These
options will then, like all other outstanding Century options, at the option of
the holder, either be exercised or assumed by Adelphia. Based on the closing
price of Adelphia Class A common stock of $56.00 on August 12, 1999, the
aggregate value of the shares under options that accelerate as a result of the
merger is approximately $7.8 million. In addition, certain executive officers
of Century have terminated their employment agreements with Century. As a
result of such termination, all Century options held by each such executive
have vested and become exercisable. See "Risk Factors Relating to Century--
Executive Officers Have Terminated Employment Agreements" on page 36.

 Century Restricted Stock Awards

   As of August 6, 1999, the executive officers of Century held an aggregate of
2,600 restricted shares of Century Class A common stock received pursuant to
Century's 1992 Management Equity Incentive Plan that vest over time and will
still be restricted as of the effective time of the merger. Pursuant to the
merger agreement, however, all restricted shares of Century Class A common
stock will become fully vested and will cease to be restricted at the effective
time of the merger. Based on the closing price of Adelphia Class A common stock
of $56.00 on August 12, 1999, the aggregate value of the restricted shares, the
vesting of which accelerate as a result of the merger, is approximately
$112,500. In addition, as a result of the termination by certain executive
officers of Century of their employment agreements discussed above, all
restricted stock held by each executive has become unrestricted. See "Risk
Factors Relating to Century--Executive Officers Have Terminated Employment
Agreements" on page 36.

 Indemnification

   The merger agreement provides that the present and former directors,
officers, employees and agents of Century and any of its subsidiaries will be
indemnified by Adelphia against all liabilities resulting from actions or
omissions arising out of such persons' services on behalf of Century or its
subsidiaries occurring at or prior to the effective time of the merger
(including the merger). The merger agreement provides that Adelphia will pay
the expenses of such persons in connection with any matter as to which they are
entitled to indemnification as such expenses are incurred. In addition,
Adelphia has agreed that all existing rights to indemnification under Century's
certificate of incorporation, bylaws or otherwise in favor of such persons will
remain in effect for a period of six years from the effective time of the
merger. Adelphia has also agreed that it will cause Merger Sub to maintain in
effect for not less than six years after the effective time directors' and
officers' liability insurance covering Century's directors and officers similar
in scope and coverage to that maintained by Adelphia for its directors and
officers.

 Other Matters

   Century, Adelphia and Dr. Tow have agreed that Century will sell its
5,139,156 shares of Citizens Utilities Company, the parent company of Citizens
Cable Company, to Dr. Tow at the effective time of the merger at fair market
value, based on the closing market price of such shares on the date the merger
agreement was signed. Based on that closing market price ($7.75), the aggregate
purchase price will be approximately $39.8 million. As of August 6, 1999, these
shares constituted approximately 2% of the outstanding stock of Citizens
Utilities Company. Dr. Tow also is the Chairman and Chief Executive Officer of
Citizens Utilities Company.

   In addition, Adelphia has agreed to purchase from Citizens Cable Company its
50% interest in the Citizens-Century Cable Television Joint Venture, which
serves approximately 91,000 basic subscribers in California. This purchase will
take place at the effective time of the merger. The purchase price for this
interest will be approximately $157.5 million, comprised of approximately $27.7
million in cash, approximately 1.85 million shares of Adelphia Class A common
stock and the assumption of indebtedness.


                                       61

   David Rosensweig, a director of Century and Secretary of Century, is a
member of the law firm of Leavy Rosensweig & Hyman, which acts as general
counsel to Century and which performed and continues to perform legal services
for Century in connection with the merger. During fiscal 1999, Century paid a
total of approximately $1.7 million to Leavy Rosensweig & Hyman for legal
services and disbursements. Mr. Rosensweig has or shares the power to vote
23,350,964 shares of Century Class B common stock in his capacity as a trustee
of two trusts established by Dr. Tow and Claire Tow.

Material Federal Income Tax Consequences

 Generally

   The following discussion addresses the material federal income tax
considerations of the merger that are generally applicable to Century
stockholders. The following discussion does not deal with all federal income
tax considerations that may be relevant to certain Century stockholders in
light of their particular circumstances, such as stockholders: who are dealers
in securities; who are banks, insurance companies, or tax-exempt organizations;
who are subject to alternative minimum tax; who hold their shares as part of a
hedge, straddle, or other risk reduction transaction; who are foreign persons;
who dissent from the merger; or who acquired their Century common stock through
stock option or stock purchase programs or otherwise as compensation. In
addition, it does not address the tax consequences of the merger under foreign,
state, or local tax laws or the tax consequences of transactions completed
before or after the merger, such as the exercise of options or rights to
purchase Century common stock in anticipation of the merger.

   Century stockholders are urged to consult their own tax advisors regarding
the tax consequences to them of the merger based on their own circumstances,
including the applicable federal, state, local, and foreign tax consequences to
them of the merger.

   The following discussion is based on the Internal Revenue Code, applicable
Treasury Regulations, judicial decisions, and administrative rulings and
practice, all as of the date of this joint proxy statement/prospectus, all of
which are subject to change. Any such change could be applied to transactions
that were completed before the change, and could affect the accuracy of the
statements and conclusions in this discussion and the tax consequences of the
merger to Century, Adelphia, and/or their respective stockholders.

   Neither Century nor Adelphia has requested or will request a ruling from the
Internal Revenue Service with regard to any of the tax consequences of the
merger. Gibson, Dunn & Crutcher LLP, counsel to Century, will render its
opinion to Century at the closing of the merger, and Buchanan Ingersoll
Professional Corporation, counsel to Adelphia, will render its opinion to
Adelphia at the closing of the merger, that:

  .  the merger should constitute a "reorganization" under Section 368(a) of
     the Internal Revenue Code; and

  .  each of Century, Merger Sub, and Adelphia should be a party to the
     reorganization within the meaning of Section 368(b) of the Internal
     Revenue Code.

   As a condition to the closing of the merger, each counsel must render an
opinion to the effect of the points listed above. The opinions that are to be
rendered at the closing of the merger will be based upon the assumption that
the merger will take place in the manner described in the merger agreement. The
opinions of counsel will also assume the truth and accuracy of certain factual
representations that have been made by Century and Adelphia and which are
customarily given in transactions of this kind.

 Consequences to Century Stockholders

   The tax consequences of the merger to a particular Century stockholder will
depend upon the form of consideration received by that stockholder. Based on
the assumption that the merger will constitute a

                                       62
<PAGE>

reorganization, and subject to the limitations and qualifications referred to
in this discussion, the following U.S. federal income tax consequences will
result from the merger:

  .  A Century stockholder who exchanges his or her shares of Century common
     stock solely for Adelphia Class A common stock (and cash in lieu of a
     fractional share) should not recognize any gain or loss, except with
     respect to the fractional share.

  .  A Century stockholder who exchanges his or her shares of Century common
     stock solely for cash will generally recognize gain (and, as is more
     fully described below, likely will be permitted to recognize loss) equal
     to the difference between the amount of cash received and the
     stockholder's basis in his or her Century common stock.

  .  A Century stockholder who exchanges his or her shares of Century common
     stock for Adelphia Class A common stock and cash (other than cash in
     lieu of a fractional share) will generally recognize gain in an amount
     equal to the lesser of:

    .  the difference between (i) the fair market value of all property
       (Adelphia Class A common stock and cash) received in the exchange
       and (ii) the stockholder's basis in the Century common stock; and

    .  the amount of cash received in the exchange.

     A Century stockholder who exchanges his or her shares of Century common
     stock for Adelphia Class A stock and cash will not be permitted to
     recognize a loss in the exchange.

  .  The total initial tax basis of the Adelphia Class A common stock
     received by a Century stockholder in the merger will be equal to the
     total tax basis of the Century common stock exchanged for the Adelphia
     stock, decreased by the amount of cash (other than cash in lieu of a
     fractional share) received in the exchange (if any), and increased by
     the amount of gain recognized in the exchange (if any).

  .  A Century stockholder who receives cash in lieu of a fractional share of
     Adelphia Class A common stock will generally recognize gain or loss in
     an amount equal to the difference between (i) the amount of cash
     received in lieu of a fractional share and (ii) the stockholder's basis
     allocated to the fractional share, determined in the manner described in
     the preceding point.

  .  The holding period of the Adelphia Class A common stock received by a
     Century stockholder in the merger will include the period for which the
     Century common stock was held, provided that such Century common stock
     was held as a capital asset at the time of the merger.

 Stockholder Receiving Adelphia Class A Common Stock and Cash--Character of
 Gain

   The gain recognized by a Century stockholder receiving a combination of
Adelphia Class A common stock and cash in the merger may be characterized as
either capital gain or ordinary income, depending upon that stockholder's
particular situation. In determining the character of the gain recognized by a
Century stockholder receiving both Adelphia Class A common stock and cash, the
Internal Revenue Service will (i) treat each Century stockholder as having
exchanged his or her Century common stock solely for Adelphia Class A common
stock and then (ii) treat each recipient of Adelphia Class A common stock as
having sold back a portion of that stock to Adelphia in exchange for cash. The
exchange of stock for cash in this fashion is known as a "redemption." Gain
recognized by a stockholder in a redemption will be treated as a capital gain
if, after giving effect to the constructive ownership rules of the Internal
Revenue Code, either:

  .  the stockholder's receipt of cash is "substantially disproportionate" to
     the stockholder's equity interest in Adelphia; or

  .  the redemption is "not essentially equivalent to a dividend."

In addition, to receive capital gain treatment, a Century stockholder must have
held his or her Century common stock as a capital asset immediately before the
merger. This capital gain would be treated as long-term capital

                                       63
<PAGE>

gain if the Century stockholder's holding period for the Century common stock
was more than one year at the effective time of the merger.

   Both of the two alternative tests given above are designed to determine
whether a stockholder experiences a significant decrease in corporate voting
power as a result of a partial redemption of his or her share holdings. In
making this determination, the constructive ownership rules of the Internal
Revenue Code must be taken into account. Under these rules, a former Century
stockholder is treated as owning, in addition to the Adelphia Class A common
stock he or she receives, or is treated as having received, in the merger,
those shares of Adelphia Class A common stock that are held or controlled by
certain related individuals or entities. Specifically:

  .  An individual stockholder is treated as owning the shares owned,
     directly or indirectly, by his or her spouse, children, grandchildren,
     and parents.

  .  A stockholder who is a partner in a partnership, a shareholder of an S
     corporation, or a beneficiary of an estate or trust, is treated as
     owning those shares owned, directly or indirectly, by the relevant
     entity, in proportion to his or her interest in the relevant entity.

  .  A stockholder who is considered the "owner" of any portion of a so-
     called "grantor trust" is treated as owning those shares owned, directly
     or indirectly, by that portion of the trust.

  .  A stockholder who owns, directly or indirectly, 50% or more of the value
     of the stock of a corporation is treated as owning those shares owned,
     directly or indirectly, by the corporation, in proportion to his or her
     ownership of the corporation.

  .  A stockholder that is a partnership or an S corporation is treated as
     owning those shares owned, directly or indirectly, by its owners.

  .  A stockholder that is an estate is treated as owning those shares owned,
     directly or indirectly, by its beneficiaries.

  .  A stockholder that is a trust is generally treated as owning those
     shares owned, directly or indirectly, by its beneficiaries, other than
     any beneficiary whose interest in the trust is (i) contingent and (ii)
     worth no more than 5% of the value of the trust property, computed
     actuarially.

  .  A stockholder that is a corporation, other than an S corporation, is
     treated as owning those shares owned, directly or indirectly, by its
     shareholders who own, directly or indirectly, 50% or more of the value
     of the stock of the corporation.

  .  A person who has an option to acquire Adelphia stock (or any option to
     acquire such an option) is treated as owning that stock.

   Once a stockholder computes the total number of shares that he or she is
treated as owning, after giving effect to the constructive ownership rules, the
stockholder must determine whether the deemed redemption satisfies the
requirements of either the "substantially disproportionate" test or the "not
essentially equivalent to a dividend" test.

   To qualify as "substantially disproportionate" with respect to a particular
stockholder, a redemption must meet three requirements, in each case taking
into account the constructive ownership rules described above. The three
requirements are that, immediately after the redemption:

  .  the stockholder must own less than 50% of the total voting power of the
     outstanding Adelphia common stock;

  .  the stockholder must own less than 80% of the percentage of voting power
     of the Adelphia common stock he or she owned or was treated as owning
     before the redemption; and


                                       64
<PAGE>

  .  the stockholder must own less than 80% of the percentage of Adelphia
     common stock (measured by fair market value) he or she owned or was
     treated as owning before the redemption.

   If a stockholder fails any part of this test, the redemption may still
qualify as "not essentially equivalent to a dividend" if it results in a
"meaningful reduction" of the stockholder's proportionate interest in Adelphia.
This is a highly subjective standard. Accordingly, neither Century, Adelphia,
nor their respective counsel can provide any substantial assurance that a
particular redemption will qualify as a meaningful reduction. However, based on
a published ruling of the Internal Revenue Service, a stockholder with a
relatively minimal interest in Adelphia and no ability to exercise any
substantial measure of control over Adelphia's corporate affairs should be
treated as having experienced a meaningful reduction of his proportionate
interest in Adelphia as a result of the deemed redemption.

   If the deemed redemption of Adelphia Class A common stock in exchange for
cash fails to satisfy both the "substantially disproportionate" test and the
"not essentially equivalent to a dividend" test with respect to a particular
Century stockholder, then the gain recognized by that stockholder will be
characterized as a distribution with respect to the stock. Such a distribution
will be treated as a dividend to the extent of the stockholder's allocable
share of Century's accumulated earnings and profits. A dividend payment
received by a stockholder is generally treated as ordinary income for federal
income tax purposes. If the amount of the distribution exceeds the
stockholder's allocable share of Century's accumulated earnings and profits,
then the excess will be treated as capital gain. A corporate stockholder that
receives a dividend may be eligible to claim a dividends-received deduction,
and may be subject to the "extraordinary dividend" provisions of the Internal
Revenue Code.

 Stockholder Receiving Solely Cash--Character of Gain and Recognition of Loss

   The character of income, gain, or loss if any, recognized by a Century
stockholder receiving solely cash in exchange for his or her Century common
stock is determined under an analysis similar to that described above, except
that the Internal Revenue Service may treat the stockholder's Century common
stock as having been redeemed by Century immediately before the merger, rather
than as having been exchanged for Adelphia common stock and then redeemed by
Adelphia immediately after the merger. In either case, if the deemed redemption
satisfies either the "substantially disproportionate" test or the "not
essentially equivalent to a dividend" test with respect to a particular Century
stockholder, or if the deemed redemption results in a complete termination of
the stockholder's interest in the relevant entity, after giving effect to the
constructive ownership rules, then any gain recognized by the stockholder will
be treated as a capital gain (provided that the stockholder held his or her
Century common stock as a capital asset immediately before the merger), and the
stockholder will be permitted to recognize loss.

   If the deemed redemption fails all three of these tests with respect to a
particular Century stockholder, then the stockholder would not be permitted to
recognize loss, and the full amount of cash received by that stockholder could
be characterized as a distribution with respect to stock, and thus be treated
as a dividend to the extent of the stockholder's allocable share of Century's
current and accumulated earnings and profits. In such an event, however, the
stockholder might nonetheless assert successfully that these three tests are
inapplicable and that he or she is entitled to receive capital gain (or capital
loss) treatment. Because of this complexity and uncertainty, Century
stockholders receiving solely cash in the merger are especially urged to
consult their own tax advisors with regard to their individual tax
consequences.

 Withholding

   Payments in respect of Century common stock or a fractional share of
Adelphia Class A common stock may be subject to information reporting to the
Internal Revenue Service and to a 31% backup withholding tax. Backup
withholding will not apply to a payment made to a stockholder who completes and
signs the substitute Form W-9 that is included as part of the transmittal
letter, or who otherwise proves to Adelphia and its exchange agent that it is
exempt from backup withholding.

                                       65
<PAGE>

 Reporting and Recordkeeping

   A Century stockholder who exchanges shares of Century common stock in the
merger for Adelphia Class A common stock, or for a combination of Adelphia
Class A common stock and cash, is required to retain records of the
transaction, and to attach to his or her federal income tax return for the year
of the merger a statement setting forth all relevant facts with respect to the
nonrecognition of gain or loss upon the exchange. At a minimum, the statement
must include (i) the stockholder's tax basis in the Century common stock
surrendered and (ii) the amount of cash (if any) and the fair market value, as
of the effective date of the merger, of the Adelphia Class A common stock
received in exchange therefor.

 Consequences to Century and Adelphia

   Assuming that the merger qualifies as a reorganization, neither Century nor
Adelphia will recognize gain or loss solely as a result of the merger.

 Caveat

   Opinions of counsel are not binding on the Internal Revenue Service or the
courts. If the Internal Revenue Service were to assert successfully that the
merger is not a reorganization within the meaning of Section 368(a) of the
Internal Revenue Code, then each Century stockholder would be required to
recognize gain or loss equal to the difference between (i) the fair market
value of all property (Adelphia Class A common stock and cash) received in the
exchange and (ii) the stockholder's tax basis in the Century common stock
surrendered therefor. In such an event, a Century stockholder's total initial
tax basis in the Adelphia Class A common stock received would be equal to its
fair market value, and the stockholder's holding period for the Adelphia Class
A common stock would begin the day after the merger. The gain or loss would be
a long-term capital gain or loss if the Century stockholder's holding period
for the Century common stock was more than one year.

   The preceding discussion does not purport to be a complete analysis of all
potential tax consequences of the merger that may be relevant to a particular
Century stockholder. Holders of Century common stock are urged to consult their
own tax advisors regarding the specific tax consequences to them of the merger,
including the applicability and effect of foreign, state, local, and other tax
laws.

Regulatory Matters

 HSR Act and Antitrust

   Adelphia and Century have observed the notification and waiting period
requirements of the HSR Act and the rules and regulations promulgated
thereunder. The HSR Act provides for an initial 30-calendar-day waiting period
following the filing with the U.S. Federal Trade Commission (the "FTC") and the
Antitrust Division of the U.S. Department of Justice (the "Antitrust Division")
of certain Notification and Report Forms by the parties to the merger. The HSR
Act further provides that, if, within the initial 30-calendar-day waiting
period, the FTC or the Antitrust Division issues a request for additional
information or documents, the waiting period will be extended until 11:59 p.m.
on the 20th day after the date of substantial compliance by the filing parties
with such request. Only one such extension of the initial waiting period is
permitted under the HSR Act; however, the filing parties may voluntarily extend
the waiting period. The HSR Act also provides the FTC and the Antitrust
Division with the option of terminating the waiting period before the end of
the 30 calendar days.

   On March 26, 1999, Adelphia and Century filed the Notification and Report
Forms with the Antitrust Division and the FTC for review in connection with the
merger. On April 20, 1999, the FTC notified the parties that the waiting period
under the HSR Act was terminated.

   Notwithstanding termination of the waiting period, the FTC, the Antitrust
Division and others could take action under the antitrust laws to challenge the
merger, including seeking to enjoin the consummation of the

                                       66
<PAGE>

merger, seeking the divestiture by Adelphia of all or part of the stock or
assets of Century or of other business conducted by Adelphia, or seeking to
subject Adelphia or Century to certain operating conditions, before or after
the merger is completed. There can be no assurance that a challenge to the
merger will not be made or that, if such a challenge is made, Adelphia will
prevail.

   The obligations of Adelphia and Century to consummate the merger are subject
to the condition that the merger not be restrained, enjoined or prohibited by
any order, judgment, decree, injunction or ruling of a court of competent
jurisdiction or any governmental entity after the parties have used their
reasonable best efforts to prevent the same, nor shall there have been any
statute, rule or regulation enacted or deemed applicable to the merger by any
governmental entity that prevents its consummation.

 Federal Communications Commission

   In addition, Adelphia and Century are required to obtain certain approvals
from the FCC. On July 9, 1999, Adelphia and Century filed the remaining
required applications with the FCC seeking approvals of the transfers of
control to Adelphia of the FCC licenses and authorizations held by certain
Century subsidiaries. In evaluating such applications, the FCC will consider
whether Adelphia is qualified to control such licenses and authorizations and
whether the public interest, convenience and necessity will be served by such
transfer of control. As required, the FCC is seeking public comments on the
applications.

 State and Local Governmental Authorities

   The merger is also subject to certain state and local governmental approvals
or actions. Century and Adelphia have filed applications in connection with the
merger with three state commissions and the franchising authority in Puerto
Rico, and with approximately 115 local franchising authorities. The filings
seek the level of review appropriate under each state's laws or local franchise
authority's franchise agreement. Where approval or consent is required for
transfers of control of cable television franchises, Adelphia and Century
believe that the appropriate governing legal standard is the legal, technical
and financial qualifications of the company acquiring control. However, certain
franchising authorities have stated that they will consider additional factors.
As of August 5, 1999, approval had been obtained or deemed obtained under
federal law, or was not required, for systems representing approximately 54% of
the total Century basic subscribers.

   Pursuant to the merger agreement, it is a condition to Adelphia's obligation
to consummate the merger that all required consents of governmental authorities
shall have been obtained prior to the effective time, except where the failure
to obtain any such required consent would not have a material adverse effect.
The failure to obtain the required consents of franchising authorities will be
deemed not to have a material adverse effect, and will therefore not prevent
this condition from being satisfied, unless the required consents that are not
obtained cover more than 50% of Century's basic subscribers (except that three
franchises to be transferred to TCI in connection with the formation of the TCI
joint venture and their approximately 86,000 basic subscribers are excluded
from this calculation). As a result of the foregoing, this condition has been
satisfied.

Appraisal Rights

 Century Stockholders

   Record holders of Century common stock that follow the appropriate
procedures are entitled to dissenters rights under Sections 14A:11-1 through
14A:11-11 of the New Jersey Business Corporation Act (the "New Jersey
Dissenters' Statute") in connection with the merger.

   The following discussion of the applicable provisions of the New Jersey
Dissenters' Statute is not intended to be a complete statement of such
provisions and is qualified in its entirety by reference to the full text of
the New Jersey Dissenters' Statute, which is reprinted in its entirety and
attached as Appendix D to this joint proxy statement/prospectus. A person
having a beneficial interest in shares of Century common stock that are held of

                                       67
<PAGE>

record in the name of another person, such as a bank, broker or other nominee,
must act promptly to cause the record holder to follow the steps summarized
below properly and in a timely manner if such person wishes to perfect any
dissenters' rights such person may have.

   This discussion and Appendix D should be reviewed carefully by any
stockholder of Century who wishes to exercise statutory dissenters' rights or
who wishes to preserve the right to do so, because failure to strictly comply
with any of the procedural requirements of the New Jersey Dissenters' Statute
may result in a termination or waiver of dissenters' rights under the New
Jersey Dissenters' Statute.

   Under the New Jersey Dissenters' Statute, each Century stockholder has the
right to dissent from the merger and demand payment of the fair value of his or
her shares of Century common stock. If a stockholder elects to dissent, the
stockholder must file with Century a written notice of dissent stating that
such stockholder intends to demand payment for his or her shares if the merger
is consummated. Such written notice of dissent must be filed with Century
before the vote of Century stockholders on the merger. Upon making such demand,
the dissenting stockholder will cease to have any of the rights of a
stockholder except the right to be paid the fair value of his or her shares and
other rights of a dissenting stockholder under the New Jersey Dissenters'
Statute. The "fair value" of the shares as used in the New Jersey Dissenters'
Statute is determined as of the day prior to the Century stockholder meeting
being held to vote upon the merger.

   Within 10 days after the effective date of the merger, Merger Sub will give
written notice of the effective date of the merger by certified mail to each
stockholder who filed a written notice of dissent, except for any stockholder
who voted for or consented in writing to the merger. Within 20 days after the
mailing of such notice, the dissenting stockholder may make written demand on
Merger Sub for payment of the fair value of his or her shares.

   Not later than 20 days after demanding payment for his or her shares, the
dissenting stockholder must submit any certificate(s) representing his or her
shares to Merger Sub for notation that such demand has been made. Such
certificate(s) will then be returned to the stockholder. No later than 10 days
after the expiration of the 20 day period in which a stockholder may make
written demand for the fair value of his or her shares, Merger Sub will mail to
each dissenting stockholder Century's financial statements as of the latest
available date. Merger Sub may accompany such mailing with a written offer to
pay each dissenting stockholder a specified price deemed by Merger Sub to be
the fair value of such stockholders' shares. If, not later than 30 days after
the expiration of the 10 day period in which Merger Sub sends out mailings to
dissenting stockholders, the fair value of the shares is agreed upon between
any dissenting stockholder and Merger Sub, payment shall be made upon surrender
of any certificate(s) representing such shares.

   If the fair value of the shares is not agreed upon within the 30 day period,
the dissenting stockholder may serve upon Merger Sub a written demand that it
commence an action in the Superior Court of New Jersey for the determination of
the fair value of the shares. Such demand must be served by the stockholder not
later than 30 days after the expiration of the 30 day period in which the
stockholder and Merger Sub could not agree upon the fair value of the shares.
Such action must be commenced by Merger Sub not later than 30 days after
receipt of such demand. If Merger Sub fails to commence the action within the
30 day period, a dissenting stockholder may do so in the name of Merger Sub,
not later than 60 days after the expiration of the 30 day period in which
Merger Sub was required to commence such an action.

   All dissenting stockholders must be made parties to the action and the court
shall render judgment for the fair value of their shares. The judgment shall
include an allowance for interest at such rate as the court finds equitable,
from the date of the dissenting stockholder's demand for payment to the day of
payment, unless the court finds that the refusal of any dissenting stockholder
to accept an offer of payment made by Merger Sub was arbitrary, vexatious or
otherwise not in good faith. The costs and expenses of bringing the appraisal
action will be determined by the court and will be apportioned and assessed as
the court may find equitable upon the parties or any of them. In addition,
reasonable fees and expenses of counsel may be assessed against Merger

                                       68
<PAGE>

Sub if the court finds that the offer of payment made by Merger Sub was not
made in good faith or if no such offer was made.

   The right of a dissenting stockholder to be paid the fair value of his or
her shares will terminate if he or she fails to strictly comply with any of the
requirements described above or in any of the following circumstances:

  .  if the dissenting stockholder's demand for payment is withdrawn with the
     written consent of Century or, after the merger, Merger Sub;

  .  if the fair value of the shares is not agreed upon and no action for the
     determination of fair value by the Superior Court of New Jersey is
     commenced within the appropriate time period;

  .  if the Superior Court of New Jersey determines that the stockholder is
     not entitled to payment for his or her shares;

  .  if the merger is abandoned; or

  .  if a court having jurisdiction permanently enjoins or sets aside the
     merger.

   If the right of a dissenting stockholder to be paid the fair value of his or
her shares terminates for any of the reasons described above, then such
dissenting stockholder shall receive $9.16426528 in cash and 0.61222732 shares
of Adelphia Class A common stock for each share of Century Class A common stock
and $11.81417001 in cash and 0.63595483 shares of Adelphia Class A common stock
for each share of Century Class B common stock.

 Adelphia Stockholders

   Under Delaware law, Adelphia stockholders will not be entitled to appraisal
rights in connection with the merger.

Federal Securities Laws Consequences

   All shares of Adelphia Class A common stock that will be issued in the
merger will be freely transferable, except for certain restrictions on
"affiliates" of Century. Shares of Adelphia Class A common stock received in
the merger by persons who are deemed to be affiliates of Century may be resold
by them only in transactions permitted by the resale provisions of Rule 145 (or
Rule 144 in the case of such persons who become affiliates of Adelphia) or as
otherwise permitted under the Securities Act. Persons who may be deemed to be
affiliates of Century are Dr. Tow, Claire Tow and their affiliates. The merger
agreement requires Century to use its reasonable best efforts to cause each of
its affiliates to execute a written agreement to the effect that such persons
will not offer or sell or otherwise dispose of any of the shares of Adelphia
Class A common stock issued to them in the merger in violation of the
Securities Act or the rules and regulations promulgated by the SEC thereunder.

   This joint proxy statement/prospectus does not cover resales of Adelphia
Class A common stock to be received by affiliates of Century in the merger, and
no person is authorized to make any use of this joint proxy
statement/prospectus in connection with any such resale.

Recent Litigation

   On or about March 10, 1999, a lawsuit was commenced by the filing of a class
action complaint by one of the holders of Century Class A common stock on
behalf of himself and all others similarly situated naming the holders of
Century Class B common stock and all of Century's directors as defendants for
alleged breaches of fiduciary duty in connection with the approval of the
merger consideration. The complaint was filed in the Superior Court in the
State of Connecticut under the caption Robert Lowinger v. Century
Communications Corp., et. al. Century and Adelphia were also named as
defendants for allegedly aiding and abetting in the foregoing alleged breaches
of fiduciary duty. The complaint seeks damages in an unspecified amount and
such other relief as may be appropriate. On July 21, 1999, the court granted
the defendants' motion for extension of time to answer or otherwise respond to
the complaint to the earlier of November 15, 1999 or twenty days after the
effective date of the merger.

                  THE MERGER AGREEMENT AND RELATED AGREEMENTS

   The following is a description of the material terms of the merger agreement
and certain related agreements. A copy of the merger agreement is attached as
Appendix A to this joint proxy statement/prospectus and is incorporated herein
by reference. Copies of the related agreements are included as exhibits to the
registration statement of Adelphia of which this joint proxy
statement/prospectus is a part and are incorporated herein by reference. To
receive copies of the exhibits, see "Where You Can Find More Information" on
page 103. The following description does not purport to describe all of the
terms of the merger agreement or the related agreements. All stockholders are
urged to read these agreements in their entirety.

The Merger Agreement

 Structure of the Merger

   Subject to the terms and conditions of the merger agreement, Century will
merge with and into Merger Sub. The separate corporate existence of Century
will cease. Merger Sub will be the surviving corporation in the merger and will
continue its corporate existence as a wholly owned subsidiary of Adelphia and
will be governed by the laws of the state of Delaware. The certificate of
incorporation and the bylaws of Merger Sub at the effective time of the merger
will become the certificate of incorporation and the bylaws of the surviving
corporation. The directors and officers of Merger Sub at the effective time of
the merger will become the directors and officers of the surviving corporation.

 Closing

   The merger will become effective at the closing, which will take place on
the date specified by Adelphia and Century (but no later than the second
business day) following the satisfaction or waiver of the conditions to the
merger (other than those conditions to be satisfied or waived at the closing)
or on such other date as Adelphia, Century and Merger Sub shall agree.

 Consideration to be Received for Century Common Stock in the Merger

   The merger agreement provides that, at the effective time, each issued and
outstanding share of Century Class A common stock (other than shares held by
dissenting stockholders and shares held by Century) will, at the election of
each holder but subject to proration as described on pages 71-72, be converted
into the right to receive:

  .  0.77269147 of a share of Adelphia Class A common stock (the "Century
     Class A Per Share Stock Amount"); or

  .  $44.14 in cash (the "Century Class A Per Share Cash Amount"), or

  .  a combination of shares of Adelphia Class A common stock and cash;

and that each issued and outstanding share of Century Class B common stock
(other than shares held by dissenting stockholders and shares held by Century)
will, at the election of each holder but subject to proration as described on
pages 71-72, be converted into the right to receive:

  .  0.84271335 of a share of Adelphia Class A common stock (the "Century
     Class B Per Share Stock Amount"); or

  .  $48.14 in cash (the "Century Class B Per Share Cash Amount"), or

  .  a combination of shares of Adelphia Class A common stock and cash.

   As of the effective time, all shares of Century Class A and Century Class B
common stock will no longer be outstanding and will automatically be canceled
and retired and will cease to exist, and each holder of a certificate
representing Century Class A or Century Class B common stock will cease to have
any rights with respect thereto, except the right to receive, upon surrender of
such certificate, in accordance with the procedures set forth herein, the
consideration set forth above, and each share of Century Class A or Century
Class B

                                       70
<PAGE>

common stock held by Century or any wholly owned subsidiary of Century will be
canceled without consideration.

 Election; Conversion of Century Shares; Proration

   Election Generally. Each record holder or beneficial owner of Century
common stock will be entitled:

  .  to elect on a share-by-share basis to receive the Century Class A Per
     Share Cash Amount or the Century Class B Per Share Cash Amount for each
     such share of Century Class A or Century Class B common stock (each a
     "Cash Election"),

  .  to elect on a share-by-share basis to receive the Century Class A Per
     Share Stock Amount or the Century Class B Per Share Stock Amount for
     each such share of Century Class A or Century Class B common stock (each
     a "Stock Election").

   All elections must be made on the form of election furnished (or a
facsimile thereof). A holder of Century common stock need not elect to receive
the same form of merger consideration with respect to all shares of Century
Class A or Class B common stock held by or on behalf of such holder.

   Limitations. Notwithstanding a Century stockholder's election at the
effective time of the merger (i) the aggregate number of shares of Century
Class A common stock that may be converted into the right to receive cash in
the merger is equal to 20.76% of the number of shares of Century Class A
common stock outstanding immediately prior to the effective time (excluding
shares held by dissenting stockholders), (ii) the aggregate number of shares
of Century Class A common stock which may be converted into the right to
receive shares of Adelphia Class A common stock in the merger is equal to

outstanding immediately prior to the effective time (excluding shares held by
dissenting stockholders), (iii) the aggregate number of shares of Century
Class B common stock that may be converted into the right to receive cash in
the merger is equal to 24.54% of the number of shares of Century Class B
common stock outstanding immediately prior to the effective time (excluding
shares held by dissenting stockholders) and (iv) the aggregate number of
shares of Century Class B common stock which may be converted into the right

75.46% of the number of such shares of Century Class B common stock
outstanding immediately prior to the effective time (excluding shares held by
dissenting stockholders).

 Proration

   Cash Oversubscription. If the aggregate number of shares of Century Class A
common stock or Century Class B common stock with respect to which Cash
Elections have been made exceeds the aggregate number of shares of Century
common stock of that class that may be converted into the right to receive
cash in the merger, then:

  .  each such share of Century common stock with respect to which a Stock
     Election was made will be converted into the right to receive the
     Century Class A Per Share Stock Amount or the Century Class B Per Share
     Stock Amount, as the case may be; and

  .  each share of Century Class A common stock with respect to which a Cash
     Election was made will be converted into the right to receive (1) the
     amount in cash, without interest, equal to the product of (a) $44.14 and
     (b) a fraction, the numerator of which will be the aggregate number of
     shares of Century Class A common stock that may be converted into the
     right to receive cash in the merger, and the denominator of which will
     be the aggregate number of shares of Century Class A common stock with
     respect to which Cash Elections were made (the "Century Class A Cash
     Fraction"), and (2) the number of shares of Adelphia Class A common
     stock equal to the product of (a) the Century Class A Per Share Stock
     Amount and (b) a fraction equal to one minus the Century Class A Cash
     Fraction; and

  .  each share of Century Class B common stock with respect to which a Cash
     Election was made will be converted into the right to receive (1) the
     amount in cash, without interest, equal to the product of

                                      71
<PAGE>

     (a) $48.14 and (b) a fraction, the numerator of which will be the
     aggregate number of shares of Century Class B common stock that may be
     converted into the right to receive cash in the merger,
     and the denominator of which will be the aggregate number of shares of
     Century Class B common stock with respect to which Cash Elections were
     made (the "Century Class B Cash Fraction"), and (2) the number of shares
     of Adelphia Class A common stock equal to the product of (a) the Century
     Class B Per Share Stock Amount and (b) a fraction equal to one minus the
     Century Class B Cash Fraction.

   Stock Oversubscription. If the aggregate number of shares of Century Class
A common stock or Century Class B common stock with respect to which Stock
Elections have been made exceeds the aggregate number of shares of Century
common stock of that class that may be converted into the right to receive
shares of Adelphia Class A common stock in the merger, then:

  .  each share of Century common stock with respect to which a Cash Election
     was made will be converted into the right to receive the Century Class A
     Per Share Cash Amount or the Century Class B Per Share Cash Amount, as
     the case may be; and

  .  each share of Century Class A common stock with respect to which a Stock
     Election was made will be converted into the right to receive (1) the
     number of shares of Adelphia Class A common stock equal to the product
     of (a) 0.77269147 and (b) a fraction, the numerator of which will be the
     aggregate number of shares of Century Class A common stock which may be
     converted into the right to receive shares of Adelphia Class A common
     stock in the merger, and the denominator of which will be the aggregate
     number of shares of Century Class A common stock with respect to which
     Stock Elections were made (the "Century Class A Stock Fraction"), and
     (2) the amount in cash, without interest, equal to the product of (a)
     the Century Class A Per Share Cash Amount and (b) a fraction equal to
     one minus the Century Class A Stock Fraction; and

  .  each share of Century Class B common stock with respect to which a Stock
     Election was made will be converted into the right to receive (1) the
     number of shares of Adelphia Class A common stock equal to the product
     of (a) 0.84271335 and (b) a fraction, the numerator of which will be the
     aggregate number of shares of Century Class B common stock which may be
     converted into the right to receive shares of Adelphia Class A common
     stock in the merger, and the denominator of which will be the aggregate
     number of shares of Century Class B common stock with respect to which
     Stock Elections were made (the "Century Class B Stock Fraction"), and
     (2) the amount in cash, without interest, equal to the product of (a)
     the Century Class B Per Share Cash Amount and (b) a fraction equal to
     one minus the Century Class B Stock Fraction.

   No Oversubscription. If there is neither a cash oversubscription nor a
stock oversubscription, then

  .  each share of Century Class A common stock or Class B common stock with
     respect to which a Cash Election was made (or deemed to have been made)
     will be converted into the right to receive the Century Class A Per
     Share Cash Amount or the Century Class B Per Share Cash Amount, as the
     case may be; and

  .  each share of Century Class A common stock or Century Class B common
     stock with respect to which a Stock Election was made (or deemed to have
     been made) will be converted into the right to receive the Century Class
     A Per Share Stock Amount or the Century Class B Per Share Stock Amount,
     as the case may be.

   Potential Value Fluctuation of Merger Consideration. The value of the
consideration that a Century stockholder receives in the merger may depend on
the value of shares of Adelphia Class A common stock, which will fluctuate, as
well as on the percentage of Century stockholders that elect to receive shares
of Adelphia Class A common stock versus cash in the merger. Since the value of
the cash portion of the merger consideration for the Century Class A common
stock is fixed at $44.14, it is expected that, if the value of 0.77269147
shares of Adelphia Class A common stock exceeds $44.14 (which will occur if
the market value of

                                      72
<PAGE>

an Adelphia Class A share is more than $57.125), holders of more than 79.24% of
the shares of Century Class A common stock will elect to receive shares of
Adelphia Class A common stock in the merger and, consequently, those Century
stockholders that elect to receive shares of Adelphia Class A common stock will
receive a combination of shares of Adelphia Class A common stock and cash in
respect of each share of Century Class A common stock. Additionally, since the
value of the cash portion of the merger consideration
for the Century Class B common stock is fixed at $48.14, it is expected that if
the value of 0.84271335 shares of Adelphia Class A common stock exceeds $48.14
(which will occur if the market value of an Adelphia Class A share is more than
$57.125), holders of more than 75.46% of the shares of Century Class B common
stock may elect to receive shares of Adelphia Class A common stock in the
merger and, consequently, those Century stockholders that elect to receive
shares of Adelphia Class A common stock may receive a combination of shares of
Adelphia Class A common stock and cash in respect of each share of Century
Class B common stock.

   The following tables illustrate the approximate value of the consideration
that a Century stockholder with 100 shares of Century Class A or Century Class
B common stock, depending on whether such stockholder makes a Stock Election or
a Cash Election, receives assuming varying values for shares of Adelphia Class
A common stock and different percentages of Century stockholders electing to
receive shares of Adelphia Class A common stock (and assuming no dissenting
shares). You should bear in mind that, notwithstanding the foregoing, (1) the
price of shares of Adelphia Class A common stock is subject to change, and (2)
neither Adelphia nor Century can predict the percentage of Century stockholders
that will make Stock Elections or Cash Elections.

   Election Procedure; Exchange of Certificates. A green form of election is
being sent contemporaneously to holders of Century Class A common stock and a
blue form of election is being sent contemporaneously to holders of Century
Class B common stock in separate mailings. Elections may be made by holders of
shares of Century common stock by delivering the appropriate form of election
to the Exchange Agent. To be effective, a form of election must be properly
completed and submitted in the return envelope for holders of Century Class A
common stock and in the return envelope for holders of Century Class B common
stock and must be received by the Exchange Agent by no later than 5:00 p.m.,
eastern time, on September 30, 1999 (the "Election Deadline"), and accompanied
by (a) the certificates as to which the election is being made or (b) an
appropriate guarantee of delivery of such certificates as set forth in such
form of election from a firm that is a member of a registered national
securities exchange or of the National Association of Securities Dealers, Inc.,
or a commercial bank or trust company having an office or correspondent in the
United States, provided that such certificates are in fact delivered to the
Exchange Agent within three (3) Nasdaq National Market trading days after the
date of execution of such guarantee of delivery (a "Guarantee of Delivery").
Failure to deliver certificates covered by any Guarantee of Delivery within
three (3) Nasdaq National Market trading days after the date of execution of
such Guarantee of Delivery will be deemed to invalidate any otherwise properly
made Cash Election or Stock Election. Adelphia has the discretion, which it may
delegate in whole or in part to the Exchange Agent, to determine whether any
form of election has been properly completed, signed and submitted or revoked
and to disregard immaterial defects in the form of election. The good faith
decision of Adelphia (or, if so delegated, the Exchange Agent) in such matters
will be conclusive and binding. Neither Adelphia nor the Exchange Agent is
under any obligation to notify any person of any defect in a form of election
submitted to the Exchange Agent. The Exchange Agent will also make all
computations contemplated by the merger agreement, and all such computations
will be conclusive and binding on the holders of shares of Century common stock
in the absence of manifest error. Any form of election may be changed or
revoked prior to the Election Deadline. In the event a form of election is
revoked prior to the Election Deadline, Adelphia will, or will cause the
Exchange Agent to, cause the certificates covered by such form of election to
be promptly returned without charge to the person submitting the form of
election upon written request to that effect from such person. A form of
election and Letter of Transmittal may be changed if the record holder
effectively revokes such holder's form of election and Letter of Transmittal in
accordance with the procedures described herein and a new form of election and
Letter of Transmittal and the related share of Century Class A or Century Class
B common stock certificate(s) (or a Guarantee of Delivery) for such record
holder is received by the Exchange Agent at or prior to the Election Deadline.
Century stockholders who do wish to revoke and resubmit should take into
account the time required to receive and resubmit certificates, which may or
may not be sufficient to allow for the receipt of returned certificates and the
resubmission of certificates by the applicable deadline.

   A Century stockholder who does not submit a form of election to the Exchange
Agent prior to the Election Deadline (including a holder who submits and then
revokes such stockholder's form of election and does not re-submit a form of
election and other required documents that are timely received by the Exchange
Agent), or who submits a form of election without the corresponding
certificates or a Guarantee of Delivery, will be deemed to have made a Stock
Election. If any form of election is defective in any manner such that the
Exchange Agent cannot reasonably determine the election preference of the
Century stockholder submitting such form of election, the purported Cash
Election or Stock Election set forth therein will be deemed to be of no force
and effect, and the Century stockholder making such purported Cash Election or
Stock Election will be deemed to have made a Stock Election.

   Century and Adelphia intend to mail, approximately 10 days prior to the
ultimate deadline for making Elections, forms of election to persons who have
become Century stockholders following the Record Date. Forms of election are
also available from the Information Agent and the Exchange Agent upon request.

 Treatment of Fractional Shares

   Upon surrender of certificates representing Century common stock after the
merger, holders of Century common stock will be paid cash instead of any
fractional shares of Adelphia Class A common stock they would otherwise
receive. All fractional shares of Adelphia Class A common stock that a holder
of shares of Century common stock otherwise would be entitled to receive as a
result of the merger will be aggregated. If a fractional share results from
such aggregation, the amount of cash to be received instead of the fractional
share will be equal to:

  .  the fraction of a share that would otherwise be received, multiplied by

  .  the closing price of a share of Adelphia Class A common stock on the
     Nasdaq National Market on the trading day immediately preceding the
     effective date of the merger.

 Treatment of Century Stock Options and Century Restricted Stock in the Merger

   At the effective time of the merger, all outstanding options to acquire
Century Class A common stock will become vested and exercisable. Each option
will, at the election of the holder, either be:

  .  exercised immediately prior to the effective time of the merger, and
     each share of Century Class A common stock to which the holder of such
     option is entitled upon such exercise will, like all other shares of
     Century Class A common stock, be converted into the right to receive
     cash and Adelphia Class A common stock as described above; or

  .  assumed by Adelphia and become an option to purchase Adelphia Class A
     common stock.

   If an option is assumed by Adelphia, the exercise price, the number of
shares purchasable pursuant to such option and the terms and conditions of
exercise of such option will be determined in accordance with Section 424 of
the Internal Revenue Code.

   At the effective time of the merger, all outstanding shares of restricted
stock of Century will become vested and unrestricted and will have the right to
receive the same consideration in the merger as other shares of Century Class A
common stock, as described above.

 Registration and Quotation of Adelphia Class A Common Stock

   In the merger agreement, Adelphia has agreed to use its reasonable best
efforts to register the shares of Adelphia Class A common stock to be issued as
consideration in the merger under the Securities Act, and to use its best
efforts to cause such shares to be approved for quotation on the Nasdaq
National Market. Such registration and quotation are conditions to the
obligations of Century to consummate the merger. The issuance of such shares in
the merger has been registered under the Securities Act pursuant to a
registration statement which has been declared effective.

  .  Board of Directors. So long as the holders of Century Class B common
     stock and their permitted assignees and transferees (as defined in the
     merger agreement) continue to own at least 10% of the outstanding common
     stock of Adelphia, they shall be entitled to nominate up to three
     members to Adelphia's board; and

  .  Citizens Joint Venture. At the effective date of the merger, Adelphia
     will purchase the 50% interest in the Citizens-Century Cable Television
     Joint Venture owned by Citizens Cable Company at a price to be agreed
     upon. Adelphia and Citizens have subsequently agreed on a purchase price
     of approximately $157.5 million, comprised of approximately $27.7
     million in cash, approximately 1.85 million shares of Adelphia Class A
     common stock and the assumption of indebtedness. After this purchase,

 Conditions to Completing the Merger

   Neither Adelphia nor Century is required to complete the merger unless
certain events have occurred. These events include:

  .  the expiration or termination of any waiting period required by the HSR
     Act (this occurred on April 20, 1999);

  .  the approval of the merger agreement and the merger by Century's
     stockholders;

  .  the registration statement with respect to the shares of Adelphia Class
     A common stock to be issued as consideration in the merger shall have
     been declared effective (this occurred on August 12, 1999); and

  .  the consummation of the merger shall not have been enjoined and shall
     not be prohibited by law.

   Adelphia and Merger Sub are not required to complete the merger unless
certain events have occurred. These events include:

  .  the accuracy of Century's representations and warranties under the
     merger agreement;

  .  Century's performance in all material respects of all covenants to be
     performed by Century under the merger agreement at or prior to the
     effective time of the merger;

  .  the receipt prior to the effective time of all required consents of
     governmental authorities, except where the failure to obtain any such
     required consent would not have a material adverse effect. The failure
     to obtain the required consents of franchising authorities will be
     deemed not to have a material adverse effect, and therefore will not
     prevent this condition from being satisfied, unless the required
     consents that are not obtained cover more than 50% of Century's basic
     subscribers (except that three franchises to be transferred to TCI in
     connection with the formation of the TCI joint venture and their
     approximately 86,000 basic subscribers are excluded from this
     calculation); and

  .  the receipt by Adelphia of an opinion of Buchanan Ingersoll Professional
     Corporation dated the effective date of the merger to the effect that
     the merger is a tax-free reorganization.

   Century is not required to complete the merger unless certain events have
   occurred. These events include:

  .  the accuracy of Adelphia and Merger Sub's respective representations and
     warranties under the merger agreement;

  .  Adelphia and Merger Sub's respective performance in all material
     respects of all covenants to be performed by them under the merger
     agreement at or prior to the effective time of the merger;

  .  the approval of the quotation on the Nasdaq National Market of the
     Adelphia Class A common stock to be issued as consideration in the
     merger; and

  .  the receipt by Century of an opinion of Gibson, Dunn & Crutcher LLP
     dated the effective date of the merger to the effect that the merger is
     a tax-free reorganization.

 Termination of the Merger Agreement

   Either Century or Adelphia may terminate the merger agreement at any time
prior to the merger, before or after it has been approved by either of their
respective stockholders. This termination may occur in the following ways:

  .  Century and Adelphia both decide to terminate it;

  .  Either of Century or Adelphia decides to terminate it, without the
     permission of the other party, because:


                                       80
<PAGE>

    .  the merger has not been completed by June 5, 2000, unless the
       failure to complete the merger by that date is due to the breach of
       any provision of the merger agreement by the party seeking to
       terminate the merger agreement;

    .  the other party has breached a representation, warranty, covenant or
       agreement such that certain conditions to the obligations of the
       party seeking to terminate the merger agreement are incapable of
       satisfaction by June 5, 2000; or

    .  a United States court or other governmental authority has issued a
       non-appealable, final ruling prohibiting the merger, or any law or
       regulation makes consummation of the merger illegal.

   If the merger agreement is terminated, neither party will have any liability
to the other except liability for breaches of the merger agreement, and each
party will pay its own fees and expenses, except as follows. If the merger
agreement is terminated other than:

    .  by mutual agreement of the parties, or

    .  by Century because of a breach by Adelphia under certain
       circumstances,

Century would be required to reimburse Adelphia for its actual costs and
expenses in connection with the merger, in an amount not to exceed $10 million.
If Century were to be acquired by a third party, or to enter into an agreement
to be acquired by a third party, within 24 months after termination, Century
would have to pay Adelphia a termination fee of $100 million.

 Amendment

   The merger agreement may be amended by the parties at any time before or
after the stockholders have approved the merger. Any amendment which by law
requires the approval of the stockholders of either Adelphia or Century will
require their subsequent approval before being effective.

agreement pursuant to its terms, or (iii) June 5, 2000.

 Sale of System

   On July 12, 1999, Dr. Tow and Adelphia signed a term sheet pursuant to which
Dr. Tow will purchase from Adelphia not less than 51% and up to 99% of an
Adelphia wholly-owned limited partnership that owns a cable television system
in Martha's Vineyard, Massachusetts. The purchase price will be an amount equal

Martha's Vineyard partnership that Dr. Tow acquires. The closing of the sale,

other things, upon the receipt by the Adelphia board of directors of a fairness
opinion. The closing of the merger is not conditioned upon the closing of the
Martha's Vineyard sale.

        UNAUDITED PRO FORMA CONDENSED CONSOLIDATED FINANCIAL INFORMATION

   The unaudited pro forma financial information presented on the following
pages is derived from the historical financial statements of Adelphia
Communications Corporation and subsidiaries ("Adelphia"), FrontierVision
Partners, L.P. and subsidiaries ("FrontierVision"), Century Communications
Corp. and subsidiaries ("Century"), Harron Communications Corp. and
subsidiaries ("Harron") and Olympus Communications, L.P. and subsidiaries
("Olympus"). The unaudited pro forma condensed consolidated balance sheet
information as of March 31, 1999 gives pro forma effect to: (i) the securities
offerings completed by Adelphia after March 31, 1999, (ii) the merger and the
pending acquisitions by Adelphia of FrontierVision, Harron and the interests in
Olympus held by subsidiaries of FPL Group ("Telesat"), and (iii) the intended
sale by Adelphia of Class B common stock to Highland Holdings (an entity
controlled by members of the family of John J. Rigas, principal shareholders of
Adelphia) to be completed prior to closing all such acquisitions, as if all
such transactions had been consummated on March 31, 1999. The unaudited pro
forma condensed consolidated statements of continuing operations information
for the nine months ended December 31, 1998 and the three months ended March
31, 1999 have been presented as if: (i) the financing and securities offerings
of Adelphia and its 66% owned subsidiary, Hyperion Telecommunications, Inc.
("Hyperion") completed after April 1, 1998, including the securities offerings
completed by Adelphia after March 31, 1999, (ii) the merger and the pending
acquisitions by Adelphia of FrontierVision, Harron and Telesat's interests in
Olympus, and (iii) the intended sale by Adelphia of Class B common stock to
Highland Holdings to be completed prior to closing the merger and such
acquisitions, had all been consummated on April 1, 1998.

   The unaudited pro forma financial information gives effect to the merger and
the pending acquisitions by Adelphia of FrontierVision, Harron and Telesat's
interests in Olympus under the purchase method of accounting and is based upon
the assumptions and adjustments described in the accompanying notes to the
unaudited pro forma condensed consolidated financial information presented on
the following pages. The allocations of the purchase prices for the merger and
the pending acquisitions of FrontierVision, Harron and Telesat's interests in
Olympus are based on preliminary estimates and are subject to final allocation
adjustments.

   The pro forma adjustments do not reflect any operating efficiencies or cost
savings that may be achievable with respect to the combined companies. The pro
forma adjustments do not include any adjustments to historical revenues for any
future price changes or any adjustments to selling and marketing expenses for
any future operating changes.

   The unaudited pro forma financial information is not necessarily indicative
of the financial position or operating results that would have occurred had the
stock repurchase, the merger, the pending acquisitions and the securities
offerings been consummated on the dates for which such transactions are being
given effect. The pro forma adjustments reflecting the consummation of the
stock repurchase, the merger, the pending acquisitions and the securities
offerings are based upon the assumptions set forth in the notes to the
unaudited pro forma condensed consolidated financial statements.

   The unaudited pro forma condensed consolidated financial information
presented on the following pages should be read in conjunction with the audited
and unaudited historical financial statements (including the notes thereto) of
Adelphia, Century and Olympus, which are contained in their respective Reports
on Form 10-K and Quarterly Reports on Form 10-Q and of FrontierVision and
Harron, which are included in Adelphia's Current Report on Form 8-K filed June
22, 1999. For information on how to obtain these reports, see "Where You Can

              NOTES TO UNAUDITED PRO FORMA CONDENSED CONSOLIDATED
                STATEMENT OF CONTINUING OPERATIONS--(Continued)

                      Nine Months Ended December 31, 1998
                             (Dollars in thousands)

(o) Represents the additional depreciation and amortization expense resulting
    from the merger. Pro forma depreciation and amortization is calculated on a
    straight-line basis consistent with Adelphia's accounting policy and with
    Adelphia's depreciation and amortization periods. The cost basis of the
    purchased assets utilized in these calculations is based on preliminary
    asset allocations among property, plant and equipment (primarily operating
    plant and equipment depreciated over 5 to 12 years) and intangible assets
    (primarily purchased franchises and goodwill amortized over 40 years) and
    is subject to final allocation adjustments.

(p) Represents amounts resulting from the non-cable television operations
    excluded from the acquisition and the incremental interest expense incurred
    from additional borrowings under Adelphia's subsidiaries' credit facilities
    to fund the acquisition.

(q) Represents the net effect of depreciation and amortization expense of non-
    cable television assets excluded from the acquisition of Harron and the
    additional depreciation and amortization expense resulting from the
    acquisition of Harron. Pro forma depreciation and amortization is
    calculated on a straight-line basis consistent with Adelphia's accounting
    policy and with Adelphia's depreciation and amortization periods. The cost
    basis of the purchased assets utilized in these calculations is based on
    preliminary asset allocations among property, plant and equipment
    (primarily operating plant and equipment depreciated over 5 to 12 years)
    and intangible assets (primarily purchased franchises and goodwill
    amortized over 40 years) and is subject to final allocation adjustments.

(r) Gives effect to the repurchase and issuance of Adelphia Class A common
    stock in connection with: (i) repurchase of approximately 1,091,524 shares
    from Telesat, (ii) 8,600,000 shares issued January 14, 1999, (iii)
    8,805,315 shares issued in the 1998 offering, (iv) 7,000,000 shares to be
    issued in the FrontierVision acquisition, (v) approximately 48,700,000
    shares to be issued in the merger, (vi) 8,000,000 shares issued April 28,
    1999, and (vii) intended sale of 6,171,824 shares of Adelphia Class B
    common stock to Highland Holdings to be completed prior to completion of
    closing the merger and the acquisitions of FrontierVision, Harron and
    Telesat's interests in Olympus, as if such transactions had been
    consummated on April 1, 1998. Diluted loss from continuing operations per
    common share is equal to basic loss from continuing operations per common
    share because Adelphia's convertible preferred stock had or would have an
    antidilutive effect; however, the convertible preferred stock could have a
    dilutive effect on earnings per share in future periods.

    consistent with Adelphia's accounting policy and with Adelphia's
    depreciation and amortization periods. The cost basis of the purchased
    assets utilized in these calculations is based on a preliminary asset
    allocation to intangible assets (primarily purchased franchises and
    goodwill amortized over 40 years) and is subject to final allocation
    adjustments.

(m) Represents the elimination of affiliate interest expense paid by
    FrontierVision on affiliate debt not assumed in the acquisition.

                STATEMENT OF CONTINUING OPERATIONS--(Continued)

                       Three Months Ended March 31, 1999
                            (Dollars in thousands)

(n) Represents reclassification of programming expense from a reduction of
    revenues to direct operating and programming expense and reclassification
    of interest income from revenues to a decrease in interest expense--net to
    conform to Adelphia's presentation.

(o) Represents the additional depreciation and amortization expense resulting
    from the merger. Pro forma depreciation and amortization is calculated on
    a straight-line basis consistent with Adelphia's accounting policy and
    with Adelphia's depreciation and amortization periods. The cost basis of
    the purchased assets utilized in these calculations is based on
    preliminary asset allocations among property, plant and equipment
    (primarily operating plant and equipment depreciated over 5 to 12 years)
    and intangible assets (primarily purchased franchises and goodwill
    amortized over 40 years) and is subject to final allocation adjustments.

(p) Represents amounts resulting from the non-cable television operations
    excluded from the acquisition and the incremental interest expense
    incurred from additional borrowings under Adelphia's subsidiaries' credit
    facilities to fund the acquisition.

(q) Represents the net effect of depreciation and amortization expense of non-
    cable television assets excluded from the acquisition of Harron and the
    additional depreciation and amortization expense resulting from the
    acquisition of Harron. Pro forma depreciation and amortization is
    calculated on a straight-line basis consistent with Adelphia's accounting
    policy and with Adelphia's depreciation and amortization periods. The cost
    basis of the purchased assets utilized in these calculations is based on
    preliminary asset allocations among property, plant and equipment
    (primarily operating plant and equipment depreciated over 5 to 12 years)
    and intangible assets (primarily purchased franchises and goodwill
    amortized over 40 years) and is subject to final allocation adjustments.

(r) Gives effect to the repurchase and issuance of Adelphia Class A common
    stock in connection with: (i) repurchase of approximately 1,091,524 shares
    from Telesat, (ii) 8,600,000 shares issued January 14, 1999, (iii)
    7,000,000 shares to be issued in the FrontierVision acquisition,
    (iv) approximately 48,700,000 shares to be issued in the merger, (v)
    8,000,000 shares issued April 28, 1999, and (vi) the intended sale of
    6,171,824 shares of Adelphia Class B common stock to Highland Holdings to
    be completed prior to completion of closing the merger and the
    acquisitions of FrontierVision, Harron, and Telesat's interests in Olympus
    as if such transactions had been consummated on April 1, 1998. Diluted
    loss from continuing operations per common share is equal to basic loss
    from continuing operations per common share because Adelphia's convertible
    preferred stock had or would have an antidilutive effect; however, the
    convertible preferred stock could have a dilutive effect on earnings per
    share in future periods.

                  COMPARISON OF CERTAIN RIGHTS OF STOCKHOLDERS
                            OF ADELPHIA AND CENTURY

   Century is a business corporation incorporated in New Jersey under the New
Jersey Business Corporation Act and Adelphia is a business corporation
incorporated in Delaware under the Delaware General Corporation Law. New Jersey
corporate law currently governs the rights of Century stockholders and Delaware
corporate law governs the rights of Adelphia stockholders. At the effective
time of the merger, each Century stockholder will become a stockholder of
Adelphia and consequently Delaware corporate law will govern their rights as
stockholders. The following is a comparison of certain provisions of New Jersey
corporate law and Delaware corporate law and the respective certificates of
incorporation and bylaws of each of Adelphia and Century. This summary does not
purport to be complete and is qualified in its entirety by reference to the
Delaware General Corporation Law and the New Jersey Business Corporation Act,
which statutes may change from time to time, and the respective certificates of
incorporation and bylaws of Century and Adelphia, which also may be amended. A
copy of the Dissenters' Rights Statute from the New Jersey Business Corporation
Act is attached as Appendix D to this joint proxy statement/prospectus and we
encourage you to read this.

Voting Requirements For Major Transactions

   Under New Jersey corporate law, unless a greater vote is specified in the
certificate of incorporation, the affirmative vote of a majority of the votes
cast by stockholders entitled to vote on the matter is required to approve:

  .  any amendment to a New Jersey corporation's certificate of
     incorporation;

  .  the voluntary dissolution of the corporation;

  .  the sale or other disposition of all or substantially all of a
     corporation's assets otherwise than in the ordinary course of business;
     or

  .  the merger or consolidation of the corporation with another corporation.

   Century's Certificate of Incorporation does not contain provisions
specifying a greater vote requirement. Under Century's Certificate of
Incorporation, the holders of Century Class A common stock are entitled to one
vote per share. The holders of the outstanding shares of a class are entitled
to vote as a class upon any proposed amendment to the certificate of
incorporation, whether or not entitled to vote thereon by the provisions of the
corporation's certificate of incorporation, if the amendment would increase or
decrease the aggregate number of authorized shares of such class, increase or
decrease the par value of the shares of such class or alter or change the
powers, preferences or specific rights of the shares of such class so as to
adversely affect them.

   Under Delaware corporate law, unless otherwise specified in the certificate
of incorporation:

  .  an amendment to the certificate of incorporation, the voluntary
     dissolution of the corporation;

  .  a sale or other disposition of all or substantially all of the assets of
     a corporation; or

  .  a merger or consolidation of a stock corporation with another stock
     corporation, requires the affirmative vote of a majority of the
     outstanding stock entitled to vote thereon. With respect to the
     amendment of the certificate of incorporation, the affirmative vote of a
     majority of the outstanding shares of stock of each class entitled to
     vote thereon as a class is also required in the election of directors
     and on all other matters presented to the stockholders and the holders
     of Century Class B common stock are entitled to ten votes per share.
     Notwithstanding the foregoing sentence, Century's Certificate of
     Incorporation provides that the holders of Century Class A common stock
     are entitled by class vote, exclusive of all other stockholders, to
     elect one director of the entire board.

   Adelphia's Certificate of Incorporation does not contain any provisions
specifying a greater vote requirement.

                                       93
<PAGE>

Cumulative Voting

   Under New Jersey corporate law, stockholders of a New Jersey corporation do
not have cumulative voting rights in the election of directors unless the
certificate of incorporation so provides. Century's Certificate of
Incorporation does not provide for cumulative voting.

   Under Delaware corporate law, stockholders of a Delaware corporation do not
have cumulative voting rights in the election of directors unless the
certificate of incorporation so provides. Adelphia's Certificate of
Incorporation does not provide for cumulative voting.

Classified Board Of Directors

   New Jersey corporate law permits a New Jersey corporation to provide for a
classified board in its certificate of incorporation and Century currently has
a classified board with nine members. The Century board is divided into two
classes, with one class of directors, consisting of a single director, elected
solely by the Century Class A stockholders, and the other directors elected by
all of the stockholders.

   Delaware corporate law permits a Delaware corporation to provide for a
classified board in its certificate of incorporation or bylaws and Adelphia
currently has a classified board with eight members. The Adelphia board is
divided into two classes, with one class of directors, consisting of a single
director, elected solely by the Adelphia Class A stockholders, and the other
directors elected by all of the stockholders.

Rights Of Dissenting Stockholders

   Stockholders of a New Jersey corporation who dissent from a merger,
consolidation, sale of all or substantially all of the corporation's assets or
certain other corporate transactions are generally entitled to appraisal
rights. No statutory right of appraisal exists, however, where the stock of the
New Jersey corporation is (1) listed on a national securities exchange, or (2)
is held of record by not less than 1,000 holders, or (3) where the
consideration to be received pursuant to the merger, consolidation or sale
consists of cash or securities or other obligations which, after the
transaction, will be listed on a national securities exchange or held of record
by not less than 1,000 holders. Stockholders of a surviving corporation
generally do not have the right to dissent from a plan of merger unless the
merger requires approval as set forth in certain sections of New Jersey
corporate law.

   Stockholders of a Delaware corporation who dissent from a merger or
consolidation of the corporation may be entitled to appraisal rights.
Stockholders have the right to dissent from such corporate actions and to
obtain payment of the fair value of their shares. There are no statutory rights
of appraisal with respect to stockholders of a corporation who meet the
following conditions:

  (1)  The shares held by the stockholders must either be:

    .  listed on a national securities exchange or designated as a national
       market system security on an interdealer quotation system by the
       National Association of Securities Dealers, Inc., or

    .  held of record by more than 2,000 stockholders,

  (2)  Such stockholders must receive either:

    .  shares of stock or depository receipts of the corporation surviving
       or resulting from the merger or consolidation, or

    .  shares of stock or depository receipts of any other corporation, and


                                       94
<PAGE>

  (3)  At the effective date of the merger or consolidation the stock or
       depository receipts received by the stockholders must be either:

    .  listed on a national securities exchange or designated as a national
       market system security on an interdealer quotation system by the
       National Association of Securities Dealers, Inc., or

    .  held of record by more than 2,000 stockholders (or cash in lieu of
       fractional share interests therein).

   Adelphia stockholders are not entitled to appraisal rights because the
Adelphia Class A common stock is presently quoted on the Nasdaq National
Market.

Stockholder Consent To Corporate Action

   Any action required or permitted to be taken at a meeting of stockholders
may be taken without a meeting if all of the stockholders entitled to vote
consent in writing. In addition, except as otherwise provided by the
certificate of incorporation (and Century's Certificate of Incorporation is
silent on this issue) New Jersey corporate law permits any action required or
permitted to be taken at any meeting of a corporation's stockholders, other
than the annual election of directors, to be taken without a meeting, without a
prior notice and without a vote, upon the written consent of stockholders who
would have been entitled to cast the minimum number of votes necessary to
authorize such action at a meeting of stockholders at which all stockholders
entitled to vote were present and voting. Under New Jersey corporate law, a
stockholder vote on a plan of merger or consolidation may be effected only:

  .  at a stockholders' meeting,

  .  by unanimous written consent of all stockholders entitled to vote on the
     issue with advance notice to any other stockholders, or

  .  by written consent of stockholders who would have been entitled to cast
     the minimum number of votes necessary to authorize such action at a
     meeting, together with advance notice to all other stockholders.

   Except as otherwise provided by the certificate of incorporation (and
Adelphia's certificate of incorporation is silent on this issue) Delaware
corporate law permits any action required or permitted to be taken at any
meeting of a corporation's stockholders to be taken without a meeting, without
a prior notice and without a vote, upon the written consent of stockholders who
would have been entitled to cast the minimum number of votes necessary to
authorize such action at a meeting of stockholders at which all stockholders
entitled to vote were present and voting.

Dividends

   Unless there are other restrictions contained in its certificate of
incorporation (and Century's certificate of incorporation does not contain any
such restriction), New Jersey corporate law generally provides that a New
Jersey corporation may declare and pay dividends on its outstanding stock so
long as the corporation is not insolvent and would not become insolvent as a
consequence of the dividend payment. Because funds for the payment of dividends
by Century must come primarily from the earnings of Century's subsidiaries, as
a practical matter, any restrictions on the ability of Century to pay dividends
act as restrictions on the amount of funds available for the payment of
dividends by Century. Century's certificate of incorporation provides for a
priority in payment of dividends among the different classes of stock. Unless
any restriction in the certificate of incorporation (and Century's certificate
of incorporation does not contain any such restriction), the board of directors
may declare the payment of dividends.

   Delaware corporate law generally limits dividends by Adelphia to an amount
equal to the excess of the net assets of Adelphia (the amount by which total
assets exceed total liabilities) over its statutory capital, or if there is no
such excess, to its net profits for the current and/or immediately preceding
fiscal year. Adelphia's certificate of incorporation provides for a priority in
payment of dividends for preferred stock over common stock. The board of
directors has the authority to declare and pay dividends.

                                       95
<PAGE>

Bylaws

   Under New Jersey corporate law, the board of directors of a New Jersey
corporation has the power to adopt, amend, or repeal the corporation's bylaws,
unless such powers are reserved in the certificate of incorporation to the
stockholders. Century's Certificate of Incorporation does not reserve such
powers to stockholders, however, the stockholders may alter or repeal those
bylaws made by the board of directors and create new bylaws.

   Under Delaware corporate law, the stockholders of a Delaware corporation
have the power to adopt, amend, or repeal the corporation's bylaws, unless such
powers also are conferred in the certificate of incorporation to the board of
directors. Either the board or the stockholders may amend Adelphia's bylaws.

Limitations of Liability Of Directors And Officers

   Under New Jersey corporate law, a New Jersey corporation may include in its
certificate of incorporation a provision which would, subject to the
limitations described below, eliminate or limit directors' or officers'
liability to the corporation or its stockholders, for damage for breach of any
duty owed to the corporation. A director or officer cannot be relieved from
liability or otherwise indemnified for any breach of duty based upon an act or
omission (1) in breach of such person's duty of loyalty to the entity or its
stockholders, (2) not in good faith or involving a knowing violation of law, or
(3) resulting in receipt by such person of an improper personal benefit.
Century's certificate of incorporation contains provisions which limit a
director's or officer's liability to the fullest extent permitted by New Jersey
law.

   Under Delaware corporate law, a Delaware corporation may include in its
certificate of incorporation a provision which would, subject to the
limitations described below, eliminate or limit directors' or officers'
liability to the corporation or its stockholders, for monetary damage for
breaches of their fiduciary duty of care. A director cannot be relieved from
liability or otherwise indemnified (1) for breach of the director's duty of
loyalty, (2) for acts or omissions not in good faith or involving intentional
misconduct or knowing violation of law, (3) for willful or negligent conduct in
paying dividends or repurchasing stock out of other than lawfully available
funds, or (4) for any transaction from which the director derives an improper
personal benefit. The power of a Delaware corporation to limit directors' or
officers' liability is substantially identical to the power of a New Jersey
corporation. Adelphia's certificate of incorporation contains provisions that
limit a director or officer's liability to the fullest extent permitted by
Delaware law.

Indemnification Of Directors And Officers

   Both the New Jersey corporate law and the Delaware corporate law generally
permit a corporation to indemnify a director or officer against his expenses
and liabilities in connection with a suit or legal proceeding involving him in
his capacity as an agent. Such legal proceeding may not be one brought by the
corporation or on behalf of the corporation. A director or officer will be
entitled to such indemnification if he:

(1) acted in good faith and reasonably believed to be in or not opposed to the
    best interests of the company and

(2) in connection with a criminal proceeding, did not have a reasonable cause
    to believe that his conduct was unlawful.

   Both the New Jersey corporate law and the Delaware corporate law require the
corporation to pay for the expenses incurred by a director or officer if he is
successful in defense of any action, suit or legal proceeding.

State Takeover Statutes

   The New Jersey Shareholders Protection Act limits certain transactions
involving an "interested stockholder" and a "resident domestic corporation." An
"interested stockholder" is one that is directly or

                                       96
<PAGE>

indirectly a beneficial owner of 10% or more of the voting power of the
outstanding voting stock of a resident domestic corporation. The New Jersey
Shareholders Protection Act prohibits certain business combinations between an
interested stockholder and a resident domestic corporation for a period of five
years after the date the interested stockholder acquired its stock, unless the
business combination was approved by the resident domestic corporation's board
of directors prior to the interested stockholder's stock acquisition date.
After the five-year period expires, the prohibition on certain business
combinations continues unless (1) the combination is approved by the
affirmative vote of two-thirds of the voting stock not beneficially owned by
the interested stockholder, (2) the combination is approved by the board prior
to the interested stockholder's stock acquisition date, or (3) certain fair
price provisions are satisfied.

   Delaware corporate law prohibits the same transactions between a Delaware
corporation and an "interested stockholder" for a period of three years
following the interested stockholder's stock acquisition date. However, an
"interested stockholder" for purposes of Delaware law is a stockholder that is
directly or indirectly a beneficial owner of 15% or more of the voting power of
the outstanding voting stock of the corporation (or its affiliate or
associate).

Consideration Of Acquisition Proposals

   New Jersey corporate law provides that in determining whether a proposal or
offer to acquire a corporation is in the best interest of the corporation, the
board may, in addition to considering the effects of any action on
stockholders, consider any of the following:

  .  the effects of the proposed action on the corporation's employees,
     suppliers, creditors and customers;

  .  the effects on the community in which the corporation operates; and

  .  the long-term as well as short-term interests of the corporation and its
     stockholders, including the possibility that those interests may be
     served best by the continued independence of the corporation.

   The statute further provides that if, based on those factors, the board
determines that any such offer is not in the best interest of the corporation,
it may reject the offer. These provisions may make it more difficult for a
stockholder to challenge the Century board's rejection of, and may facilitate
the board's rejection of, an offer to acquire Century.

   There are no comparable provisions in Delaware corporate law.

Preferred Stock

   Except under certain circumstances, Century can issue new shares of
authorized but unissued common stock or preferred stock without stockholder
approval.

   Adelphia can issue new shares of authorized but unissued common stock or
preferred stock without stockholder approval.

Preemptive Rights

   Under New Jersey corporate law, the stockholders of corporations organized
after January 1, 1969 do not have preemptive rights unless the certificate of
incorporation provides for them. If a corporation elects to grant its
stockholders preemptive rights, then each of the stockholders will have the
right to acquire a pro rata portion of shares issued for cash, or options to
buy such shares, of the same class as those held by the stockholder. Century
was organized after January 1, 1969 and its certificate of incorporation does
not grant preemptive rights to the stockholders.

   Under the Delaware corporate law, stockholders only have preemptive rights
as may be provided in the certificate of incorporation. Adelphia's certificate
of incorporation does not provide for preemptive rights.

                                       97

                              THE SPECIAL MEETINGS

   This joint proxy statement/prospectus is furnished in connection with the
solicitation of proxies:

  .  from the holders of Adelphia common stock by the Adelphia board for use
     at the Adelphia special meeting; and

  .  from the holders of Century common stock by the Century board for use at
     the Century special meeting.

   This joint proxy statement/prospectus and accompanying form of proxy are
first being mailed to the respective stockholders of Adelphia and Century on or
about August 16, 1999. This joint proxy statement/prospectus is also furnished
to Century stockholders as a prospectus in connection with the issuance by
Adelphia of shares of Adelphia Class A common stock in connection with the
merger.

Adelphia Special Meeting

 Time And Place; Purposes

   The Adelphia special meeting will be held at the Coudersport Theatre, Main
Street, Coudersport, Pennsylvania, on Friday, October 1, 1999, at 10:00 a.m.
local time. At the Adelphia special meeting (and any adjournment or
postponement thereof), Adelphia stockholders will be asked to consider and vote
upon the Adelphia merger proposal. Representatives from Deloitte & Touche LLP,
independent accountants for Adelphia, are expected to be present at the
Adelphia special meeting, to have the opportunity to make a statement if they
so desire and to be available to respond to appropriate questions.

 Record Date; Voting Rights; Votes Required For Approval

   The Adelphia board has fixed the close of business on August 12, 1999 as the
record date for the determination of the holders of Adelphia Class A common
stock and Adelphia Class B common stock entitled to receive notice of and to
vote at the Adelphia special meeting.

   Only stockholders of record as of the close of business on August 12, 1999
are entitled to notice of and to vote at the Adelphia special meeting and any
adjournment thereof. The outstanding Adelphia common stock on the Adelphia
record date consisted of 50,328,343 shares of Adelphia Class A common stock,
$.01 par value, and 10,834,476 shares of Adelphia Class B common stock, $.01
par value. With respect to the matters described in this joint proxy
statement/prospectus, the holders of Adelphia Class A common stock and of
Adelphia Class B common stock vote together as a single class. Each holder of
Adelphia Class A common stock is entitled to cast one vote for each share of
Adelphia Class A common stock standing in his name on the books of Adelphia and
each holder of Adelphia Class B common stock is entitled to cast ten votes for
each share of Adelphia Class B common stock standing in his name on the books
of Adelphia. The presence, in person or by proxy, of holders of a majority of
the votes of all outstanding shares of Adelphia common stock entitled to vote
is necessary to constitute a quorum at the Adelphia special meeting. A majority
of the votes of all outstanding shares of Adelphia common stock entitled to
vote and represented at the Adelphia special meeting is required to approve the
Adelphia merger proposal.

 Voting And Revocation Of Proxies

   All shares represented by valid proxies received by Adelphia prior to the
Adelphia special meeting will be voted at the Adelphia special meeting as
specified in the proxy, unless such proxies previously have been revoked. If no
specification is made, the shares will be voted FOR the Adelphia merger
proposal. Unless otherwise indicated by the stockholder, the proxy card also
confers discretionary authority on the board appointed proxies to vote the
shares represented by the proxy on any matter that is properly presented for
action at the Adelphia special meeting. A stockholder giving a proxy has the
power to revoke it any time prior to its exercise by delivering to the
Secretary of Adelphia a written revocation or a duly executed proxy bearing a
later date, or by attendance at the Adelphia special meeting and voting his
shares in person.

   Under Nasdaq National Market rules, brokers who hold shares in street name
for customers have the authority to vote on certain "routine" proposals when
they have not received instructions from beneficial owners. Under Nasdaq
National Market rules, such brokers are precluded from exercising their voting
discretion with respect to proposals for non-routine matters such as the
Adelphia merger proposal. Thus, absent specific instructions from the
beneficial owner of such shares, brokers are not empowered to vote such shares
with respect to the approval and adoption of the Adelphia merger proposal
(i.e., "broker non-votes").

   At the Adelphia special meeting, matters, including the Adelphia merger
proposal, will be decided by the affirmative vote of a majority of the votes of
all outstanding shares of Adelphia common stock entitled to vote and
represented at the meeting. Abstentions and broker non-votes will be counted as
shares present for purposes of determining whether a quorum is present.
Abstentions will count as shares entitled to vote and represented at the
Adelphia special meeting and not voting in favor of the proposal. Broker non-
votes will not count as shares entitled to vote and represented at the Adelphia
special meeting and will not be included in calculating the number of votes
necessary for approval of the Adelphia merger proposal.

   As of August 6, 1999 the directors and officers of Adelphia beneficially
owned approximately 15,031,469 shares of outstanding Adelphia Class A common
stock and approximately 10,736,544 shares of outstanding Adelphia Class B
common stock. Adelphia expects that each of its directors and officers will
vote his or her shares in favor of approval of the merger. Pursuant to the
Rigas Class B Voting Agreement, certain of the holders of the Adelphia Class B
common stock, who held approximately 77.1% of the votes of all outstanding
shares of Adelphia common stock as of August 6, 1999, have agreed with Century
that they will vote in favor of the merger.

 Costs of Solicitation

   Adelphia will pay the expenses in connection with the printing, assembling
and mailing to Adelphia stockholders of this joint proxy statement/prospectus.
In addition to the use of the mails, proxies may be solicited by directors,
officers or regular employees of Adelphia personally, by telephone or by
telecopy. Adelphia may request persons holding shares for others in their
names, or in the names of their nominees, to send proxy material to and obtain
proxies from their principals, and will reimburse such persons for their
expense in so doing.

Century Special Meeting

 Time and Place; Purposes

   The Century special meeting will be held at the law offices of Gibson, Dunn
& Crutcher LLP, 200 Park Avenue, 48th Floor, New York, NY 10166, on Friday,
October 1, 1999, at 10:00 a.m., local time. At the Century special meeting (and
any adjournment or postponement thereof), Century stockholders will be asked to
consider and vote upon the merger agreement. Century stockholders may also be
asked to vote upon a proposal to adjourn or postpone the Century special
meeting to allow additional time for the solicitation of additional votes to
approve the merger agreement if the Secretary of the meeting determines that
there are not sufficient votes to approve the merger agreement. Stockholders
may also consider and act upon such other matters as may properly come before
the special meeting or any adjournment or adjournments thereof. Representatives
from Deloitte & Touche LLP, independent accountants for Century, are expected
to be present at the Century special meeting, to have the opportunity to make a
statement if they so desire and to be available to respond to appropriate
questions.

 Record Date; Voting Rights

   Century's board has selected the close of business on August 12, 1999 as the
record date for determining the holders of outstanding shares of Century Class
A common stock and Century Class B common stock entitled to receive notice of
and vote at the special meeting. Only holders of record of shares of Century
common stock on the record date will be entitled to vote at the special
meeting. On August 6, 1999, there were 33,500,875 shares of Century Class A
common stock outstanding held by 963 holders of record and

                                       99
<PAGE>

42,322,059 shares of Century Class B common stock outstanding held by three
holders of record. Holders of Century Class A common stock are entitled to one
vote per share and holders of Century Class B common stock are entitled to ten
votes per share. The shares of Century Class A common stock and Century Class B
common stock will vote as separate classes on the approval of the merger
agreement. On any other matter that may come before the Century special
meeting, the shares of Century Class A common stock and Century Class B common
stock will vote together as a single class unless otherwise required by law.

 Vote Required

   Votes at the special meeting will be tabulated by the inspector of election
appointed by Century. Shares of Century common stock represented by a properly
signed and returned proxy will be considered present at the special meeting for
purposes of determining a quorum.

   The presence either in person or by proxy of the holders of shares of
Century common stock entitled to cast a majority of the votes at the special
meeting will constitute a quorum for the transaction of business at the special
meeting. In order for a quorum of the Century Class A common stock to be
present for the vote on the approval of the merger agreement, holders of a
majority of the outstanding shares of Century Class A common stock entitled to
vote at the special meeting must be present either in person or by proxy. In
order for a quorum of the Century Class B common stock to be present for the
vote on the approval of the merger agreement, holders of a majority of the
outstanding shares of Century Class B common stock entitled to vote at the
special meeting must be present either in person or by proxy.

   Under New Jersey law and Century's Certificate of Incorporation, in order
for the merger agreement to be approved by Century's stockholders, each of the
following must vote in favor of approval of the merger agreement:

  .  a majority of the votes cast by the holders of Century Class A common
     stock entitled to vote at the special meeting, and

  .  a majority of the votes cast by the holders of Century Class B common
     stock entitled to vote at the special meeting.

   All of the Century Class B common stock is held by Dr. Leonard Tow, who is
the Chairman and Chief Executive Officer of Century, and two trusts established
by Dr. Tow and Claire Tow, who is a director of Century and the spouse of
Leonard Tow. Pursuant to a voting agreement, all of the holders of Century
Class B common stock have agreed with Adelphia that they will vote in favor of
approval of the merger agreement. In addition, the directors and executive
officers of Century and their affiliates hold approximately 1,158,000 shares of
Century Class A common stock, constituting approximately 3.5% of the
outstanding shares of Century Class A common stock.

   Brokers holding shares for beneficial owners must vote those shares
according to the specific instructions they receive from the owners. If
specific instructions are not received from a beneficial owner, a broker may
not vote the shares held for that beneficial owner on the matters to be voted
on at the special meeting. This results in a "broker non-vote."

   Abstentions and broker non-votes will be counted as shares present for
purposes of determining whether a quorum is present but will not count as votes
cast for or against the merger agreement or any other proposal and will not be
included in calculating the number of votes necessary for approval of the
merger agreement or any other proposal. Accordingly, matters will be determined
at the special meeting by a majority of the votes actually cast, and an
abstention or a broker non-vote will have the effect of a vote not cast, and
will not have the same effect as either a vote in favor of or against a matter.


                                      100
<PAGE>

 Voting of Proxies

   All shares represented by properly executed proxies will be voted at the
special meeting in accordance with the directions given on such proxies. If no
direction is given, a properly executed proxy will be voted FOR the approval
of the merger agreement. Proxies voted against the merger agreement will not
be voted in favor of any adjournment or postponement of the special meeting
for the purpose of soliciting additional proxies. Century's board does not
anticipate that any other matters will be brought before the special meeting.
If, however, other matters are properly presented, the persons named in the
proxy will have discretion, to the extent allowed by New Jersey law, to vote
in accordance with their own judgment on such matters.

   For Century's special meeting, Century's stockholders of record will have a
choice of voting by telephone using the enclosed instructions or by returning
the proxy card. If shares of a Century stockholder are registered in the name
of a bank, broker or other nominee, then such Century stockholder should check
the information forwarded by the bank, broker or other nominee to see if the
telephone voting option is available. Any stockholder present at Century's
special meeting may, nevertheless, vote in person on all matters with respect
to which he or she is entitled to vote.

   If a Century stockholder receives more than one proxy card because his or
her shares are registered in different names or addresses, and the Century
stockholder is not voting by telephone, then the Century stockholder should
sign and return each proxy card to assure that all of his or her shares will
be voted at the special meeting. If a Century stockholder is voting by
telephone, then the Century stockholder must vote once by telephone for each
different name or address in which the shares are registered.

 Revocation of Proxies

   Any stockholder may revoke a proxy at any time before such proxy is voted.
Proxies may be revoked by:

  .  delivering to the Assistant Secretary of Century a written notice of
     revocation bearing a date later than the date of the proxy;

  .  duly executing a subsequent proxy relating to the same shares of Century
     common stock and delivering it to the Assistant Secretary of Century; or

  .  attending the Century special meeting and stating to the Secretary of
     Century an intention to vote in person and so voting.

   Attendance at the Century special meeting will not in and of itself
constitute revocation of a proxy. Any subsequent proxy or written notice of
revocation of a proxy should be delivered to Century Communications Corp., 50
Locust Avenue, New Canaan, Connecticut 06840, Attention: Scott N. Schneider,
Assistant Secretary.

 Costs of Solicitation

   Century will bear all costs of soliciting proxies in the accompanying form
from Century stockholders. Solicitation will be made by mail, and officers and
regular employees of Century may also solicit proxies by telephone, telegraph
or personal interview. Century has also made arrangements with Beacon Hill
Partners, Inc. to assist in soliciting proxies and has agreed to pay Beacon
Hill Partners, Inc. approximately $9,500 plus expenses for its services. In
addition, Century expects to request persons who hold shares in their names
for others to forward copies of this proxy soliciting material to them and to
request authority to execute proxies in the accompanying form, and Century
will reimburse such persons for their out-of-pocket and reasonable clerical
expenses in doing this.

 Surrender of Certificates

   Stockholders should not send in any stock certificates with their proxy
cards. In order to make a valid election, all Century stockholders must
surrender their certificates with the form of election or use the guaranteed
delivery procedures outlined in the general instructions of the form of
election and letter of transmittal.

<PAGE>

of the shares held by such holder (including shares held by Dissenting
Shareholders as of the Election Deadline as to which appraisal rights are
subsequently withdrawn, not perfected or forfeited) or (ii) shall have properly
revoked and not properly submitted to the Exchange Agent a subsequent Election
Form with respect to all or certain of the shares, such holder will be deemed
to have made the Class A Stock Election or Class B Stock Election, as
applicable, with respect to such shares.

with respect to which Class A Cash Elections have been made exceeds the
aggregate number of shares of Class A Company Common Stock which, pursuant to
Section 1.02(a)(iii) hereof, may be converted into the right to receive cash in

    cash in the Merger, and the denominator of which shall be the aggregate

   Section 1.05 Letter of Transmittal. On or prior to the Effective Time,
Parent will authorize one or more commercial banks or trust companies
acceptable to the Company, organized under the laws of the United States or any
state thereof, to act as Exchange Agent hereunder (the "Exchange Agent").
Promptly after the Effective Time, Parent will cause the Exchange Agent to mail
to each record holder of Company Common Stock at the Effective Time (i) a
letter of transmittal (the "Letter of Transmittal") that will specify that
delivery will be effected, and risk of loss and title to the certificates
formerly representing the Company Common Stock will pass, upon delivery of such
certificates to the Exchange Agent and will be in such form and have such other
provisions, including appropriate provisions with respect to back-up
withholding, as Parent reasonably may specify and (ii) instructions for use in
effecting the surrender of the certificates formerly representing shares of
Company Common Stock in exchange for the Merger Consideration.

   Section 1.06 Deposit of Merger Consideration. On or prior to the Effective
Time, Parent will deposit with the Exchange Agent, for the benefit of the
former holders of Company Common Stock, cash and certificates sufficient to pay
the Merger Consideration for all the shares of Company Common Stock. The shares
of Parent Common Stock into which shares of Company Common Stock will be
converted pursuant to the Merger will be deemed to have been issued at the
Effective Time for purposes of entitlement to dividends declared, if any, after
the Effective Time.

   Section 1.07 Surrender and Payment.

   (a) Upon surrender for cancellation to the Exchange Agent of a certificate
formerly representing shares of Company Common Stock, together with the Letter
of Transmittal, duly executed and completed in accordance with the instructions
thereto, the holder thereof will be entitled to receive (i) a certified or bank
cashier's check in the amount equal to the aggregate amount of Merger
Consideration that takes the form of cash which such holder has the right to
receive pursuant to the provisions of this Article I (including any dividends
or distributions related thereto which such former holder of Company Common
Stock is entitled to receive pursuant to the provisions of Section 1.07(c) and
any cash in lieu of fractional shares of Parent Common Stock pursuant to
Section 1.09) and/or (ii) certificates representing the aggregate number of
shares of Parent Common Stock with respect to the Merger Consideration that
takes the form of Parent Company Stock which such holder has the right to
receive pursuant to the provisions of this Article I, less the amount of any
required withholding taxes, if any, in accordance with Section 1.10. After the
Effective Time and until so surrendered, each certificate representing shares
of Company Common Stock will represent for all purposes only the right to
receive the Merger Consideration.

   (b) If the Merger Consideration (or any portion thereof) is to be delivered
to a Person other than the Person in whose name the surrendered certificate or
certificates are registered, it will be a condition of such delivery that the
surrendered certificate or certificates shall be properly endorsed or otherwise
be in proper form for transfer and that the Person requesting such payment
shall pay any transfer or other Taxes required by reason of the delivery of the
Merger Consideration to a Person other than the registered holder of the
surrendered certificate or certificates or such Person shall establish to the
satisfaction of the Exchange Agent that any such Tax has been paid or is not
applicable.

   (c) No dividends or other distributions declared or made with respect to
Parent Common Stock on or after the Effective Time will be paid to the holder
of any certificate that theretofore evidenced shares of Company Common Stock
until such certificate is surrendered as provided in this Section 1.07. Upon
such surrender,

                                      A-9
<PAGE>

Parent will be pay to the holder of the certificates evidencing shares of
Parent Common Stock issued in exchange therefor, without interest, the amount
of dividends or other distributions with a record date after the Effective Time
payable with respect to shares of Parent Common Stock.

   (d) Any portion of the Merger Consideration made available to the Exchange
Agent pursuant to Section 1.06 that remains unclaimed by holders of shares of
Company Common Stock two years after the Effective Time will be returned to
Parent upon demand. Any such holder who has not exchanged shares of Company
Common Stock for the Merger Consideration in accordance with this Article I
prior to that time thereafter will look only to Parent for payment of the
Merger Consideration in respect of such shares of Company Common Stock.

   Section 1.08 Adjustments. If at any time during the period between the date
of this Agreement and the Effective Time, any change in the outstanding shares
of capital stock of Parent occurs, including by means of any reclassification,
recapitalization, stock split or combination, exchange or readjustment of
shares, or any stock dividend thereon with a record date during such period,
the Merger Consideration will be adjusted appropriately.

   Section 1.09 Fractional Shares. No fractional shares of Parent Common Stock
will be issued in the Merger. All fractional shares of Parent Common Stock that
a holder of shares of Company Common Stock otherwise would be entitled to
receive as a result of the Merger will be aggregated. If a fractional share
results from such aggregation, in lieu thereof such holder will be entitled to
receive from Parent, promptly after the Effective Time, an amount in cash
determined by multiplying the closing price of a share of Parent Common Stock
on the Nasdaq National Market on the trading day immediately preceding the
Effective Time by the fraction of a share of Parent Common Stock to which such
holder would otherwise have been entitled.

   Section 1.10 Withholding of Tax. Parent or the Exchange Agent will be
entitled to deduct and withhold from the consideration otherwise payable
pursuant to this Agreement to any former holder of Company Common Stock such
amounts as Parent or the Exchange Agent are required to deduct and withhold
with respect to the making of such payment under the Code, or any provision of
state, local or foreign Tax law. To the extent that amounts are so withheld by
Parent or the Exchange Agent, such withheld amounts will be treated for all
purposes of this Agreement as having been paid to the former holder of Company
Common Stock in respect of whom such deduction and withholding was made by
Parent.

   Section 1.11 Lost Certificates. If any certificate evidencing Company Common
Stock has been lost, stolen or destroyed, upon the making of an affidavit of
that fact by the Person claiming such certificate to be lost, stolen or
destroyed and, if reasonably required by Parent, the posting by such Person of
a bond in such reasonable amount as Parent may direct as indemnity against
claims that may be made against it with respect to such certificate, the
Exchange Agent will issue in exchange for such lost, stolen or destroyed
certificate the Merger Consideration to which such Person may be entitled
pursuant to this Article I and cash and any dividends or other distributions to
which such Person may be entitled pursuant to Section 1.06(a).

   Section 1.12 Stock Transfer Books. At the Effective Time, the stock transfer
books of the Company will be closed and there will be no further registration
of transfers of shares of Company Common Stock on the records of the Company.
Certificates formerly representing shares of Company Common Stock that are
presented to the Surviving Corporation after the Effective Time will be
canceled and exchanged for certificates representing shares of Parent Common
Stock.

   Section 1.13 Shareholder Approval. This Agreement will be submitted for
adoption and approval to the holders of shares of Class A Company Common Stock
and the holders of shares of Class B Company Common Stock at the Company
Shareholder Meeting (as defined in Section 7.03) in accordance with the
provisions of this Agreement. The affirmative vote of a majority of the votes
cast by the holders of shares entitled to vote thereon of Class A Company
Common Stock and Class B Company Common Stock (voting as separate classes) is
required to approve this Agreement. No other approval of the Company's
shareholders is required in order to consummate the Merger.

  Amount or (y) the Century Class A Per Share Stock Amount, as provided in
  Sections 1.02 and 1.03; or

     (ii) will be assumed by Parent and converted into an option to purchase,

  exercise price, the number of shares purchasable pursuant to such Option
  and the terms and conditions of exercise of such Option to be determined

  accompanying the Proxy Statement/Prospectus.

   (c) Parent will take all corporate action necessary to reserve for issuance
a sufficient number of shares of Parent Common Stock for delivery upon exercise
of Options assumed by it in accordance with this Section 1.14. Promptly after
the Effective Time, Parent will file with the SEC a registration statement on
Form S-3 or S-8, as appropriate, covering the shares of Parent Common Stock
subject to such Options and will use its commercially reasonable efforts to
cause such registration statement to remain effective for so long as such
Options remain outstanding.

                 REPRESENTATIONS AND WARRANTIES OF THE COMPANY

   The Company represents and warrants to Parent that, except for inaccuracies
in the representations and warranties resulting from compliance by the Company
with any of its obligations under this Agreement or actions taken by the
Company in accordance with this Agreement and except as disclosed in the
Company Disclosure Schedule:

   Section 3.01 Corporate Existence and Power. The Company is a corporation
duly incorporated, validly existing and in good standing under the laws of the
State of New Jersey and has all corporate power required to carry on its
business as now conducted. The Company is duly qualified to do business as a
foreign corporation and is in good standing in each jurisdiction where the
character of the property owned or leased by it or the nature of its activities
makes such qualification necessary, except for those jurisdictions where the
failure to be so qualified or be in good standing would not have a Material
Adverse Effect. The Company has delivered to Parent copies of the Company's
certificate of incorporation and by-laws as currently in effect.

   Section 3.02 Corporate Authorization. The execution, delivery and
performance by the Company of this Agreement and the consummation by the
Company of the transactions contemplated hereby are within the Company's
corporate powers and, except for the approval and adoption by the Company's
shareholders of this Agreement and the Merger, have been duly authorized by all
necessary corporate action on the part of the Company. This Agreement has been
duly and validly executed and delivered by the Company and, assuming the due
and valid authorization, execution and delivery of this Agreement by Parent and
Merger Sub and receipt of all required approvals by the Company's shareholders
in connection with the consummation of the Merger, constitutes a valid and
binding agreement of the Company, enforceable in accordance with its terms
except as may be limited by bankruptcy, insolvency, reorganization, moratorium,
fraudulent transfer and other similar laws affecting creditors' rights
generally and by equitable principles of general applicability. The Board of
Directors of the Company (the "Company Board") has approved the Merger, this
Agreement, the Class B Voting Agreement and the transactions contemplated
hereby and thereby and such approval, assuming the accuracy of the
representation in Section 4.14, is sufficient to render the provisions of
Article 14A:10A of the NJBCA inapplicable to the Merger, this Agreement, the
Class B Voting Agreement and the transactions contemplated hereby and thereby.
No other corporate proceedings on the part of the Company are necessary to
authorize or approve this Agreement or to consummate the transactions
contemplated hereby (other than the approval and adoption of the Merger and
this Agreement by the shareholders of the Company to the extent required by the
Company's certificate of incorporation and by applicable law).

   Section 3.03 Governmental Authorization. The execution, delivery and
performance by the Company of this Agreement and the consummation by the
Company of the Merger and the other transactions contemplated hereby require no
consent, waiver, approval, authorization or permit by or from, or action by or
in respect of, or filing with, any Governmental Entity, other than: (i) the
filing of certificates of merger as contemplated by Section 1.01(c); (ii)
compliance with any applicable requirements of state takeover laws; (iii)
compliance with the applicable requirements of the Hart-Scott-Rodino Antitrust
Improvements Act of 1976 as amended and the rules and regulations thereunder
(the "HSR Act"); (iv) compliance with any applicable requirements of the
Securities Act of 1933, as amended (together with the rules and regulations
promulgated thereunder, the "Securities Act") and the Securities Exchange Act
of 1934, as amended (together with the rules and regulations promulgated
thereunder, the "Exchange Act"); (v) compliance with any applicable
requirements of the Communications Act of 1934, as amended (together with the
rules, regulations and published decisions of the FCC (as defined below), the
"Communications Act"); (vi) filings under state securities or "blue-sky" laws;
(vii) notice to, or consents, approvals or waivers from, the relevant
Franchising

                                      A-12

Authorities or other third parties in connection with a change of control of
the holder of the Franchises of the Company and the Company Subsidiaries and of
the Federal Communications Commission (the "FCC") in connection with a change
of control or a transfer of assets of the holder of the FCC licenses of the
Company and the Company Subsidiaries; and (viii) such consents, waivers,
approvals, authorizations, permits, filings or actions that, if not taken, made
or obtained, would not in the aggregate have a Material Adverse Effect.

   Section 3.04 Non-contravention. Assuming compliance with the matters
referred to in Section 3.03, the execution, delivery and performance by the
Company of this Agreement and the consummation by the Company of the
transactions contemplated hereby do not and will not: (i) assuming receipt of
the approval of shareholders of the Company referred to in Section 3.02,
contravene or conflict with the certificate of incorporation or by-laws of the
Company; (ii) contravene or conflict with or constitute a violation of any
provision of any law, regulation, judgment, injunction, order or decree binding
upon or applicable to the Company or any Company Subsidiary that would be a
significant subsidiary within the meaning of Regulation S-X under the Exchange
Act (a "Significant Subsidiary of the Company"); (iii) result in a breach or
violation of or constitute a default (or an event that with the giving of
notice or the lapse of time or both would constitute a default) under or give
rise to a right of termination, amendment, cancellation or acceleration of any
right or obligation of the Company or any Significant Subsidiary of the Company
or to a loss of any material benefit to which the Company or any Significant
Subsidiary of the Company is entitled or require any consent, approval or
authorization under any provision of any material agreement, contract or other
instrument binding upon the Company or any Significant Subsidiary of the
Company or any of their respective assets (including any material license,
franchise, permit or other similar authorization held by the Company or any
Significant Subsidiary of the Company); or (iv) result in the creation or
imposition of any Lien on any material asset of the Company or any Significant
Subsidiary of the Company, except for such contraventions, conflicts or
violations referred to in clause (ii) and breaches, violations, defaults,
rights of termination, amendment, cancellation or acceleration, losses, Liens
or other occurrences referred to in clauses (iii) and (iv) (each, a
"Violation") that in the aggregate would not have a Material Adverse Effect.
Upon consummation of the Company's joint venture agreement with TCI

standing under the laws of its jurisdiction of organization, has all corporate,
partnership or similar powers required to carry on its business as now
conducted and is duly qualified to do business as a foreign corporation or
other legal entity and (if applicable) is in good standing in each jurisdiction
where the character of the property owned or leased by it or the nature of its
activities makes such qualification necessary, except where the failure to be

health, medical or life

                                      A-15

insurance or other benefits) that (i) is entered into, maintained, administered
or contributed to, as the case may be, by the Company or any Company Subsidiary
and (ii) covers any employee or former employee of any Company or Company
Subsidiary employed in the United States or Puerto Rico (each, an "Employee
Plan").

   (b) The Company has furnished or made available to Parent copies of the
Employee Plans (and, if applicable, related trust agreements) and all
amendments thereto and written interpretations thereof together with the most
recent annual report (Form 5500 including, if applicable, Schedule B thereto)
and the most recent actuarial valuation report prepared in connection with any
Employee Plan. There is no material accumulated funding deficiency, termination
or partial termination, or requirement to provide security with respect to any
Employee Plan. The fair market value of the assets of each material Employee
Plan would exceed the value of all liabilities and the obligations of such
Employee Plan if such plan were to terminate on the Closing Date. The
transaction contemplated by this Agreement will not result in any material
liability under ERISA to the Company or any of the Company's Subsidiaries or
Parent, or any of their respective ERISA Affiliates.

   (c) Each Employee Plan that is intended to be qualified under Section 401(a)
of the Code has been determined by the Internal Revenue Service to be qualified
under Section 401(a) of the Code and each trust related thereto has been
determined to be exempt from tax pursuant to Section 501(a) of the Code. The
Company is not aware of any event that has occurred since the date of such
determinations that would adversely affect such qualification or tax exempt
status. The Company has provided Parent with the most recent determination
letter of the Internal Revenue Service relating to each such Employee Plan.
Each Employee Plan has been maintained in compliance in all material respects
with its terms and with the requirements prescribed by any and all applicable
statutes, orders, rules and regulations, including the Employee Retirement
Income Security Act of 1974, as amended ("ERISA") and the Code.

   (d) No Employee Plan is a Multiemployer plan as defined in Section 3(37) of
ERISA or is a plan subject to Title IV of ERISA. Neither the Company nor any
Company Subsidiary or any of their ERISA Affiliates (or any former ERISA
Affiliate with respect to the period in which such entity was an ERISA
Affiliate) has ever maintained, adopted or established, contributed or been
required to contribute to, or otherwise participated or been required to
participate in, any such plan.

   (e) Neither the Company nor any Company Subsidiary has any current or
projected material liability in respect of post-employment or post-retirement
health or medical or life insurance benefits for retired, former or current
employees of the Company, except as required to avoid excise tax under Section
4980B of the Code.

   (f) There has been no amendment to, written interpretation of or
announcement by the Company, any Company Subsidiary or their respective
Affiliates relating to, or change in employee participation or coverage under,
any Employee Plan that would increase materially the expense of maintaining
such Employee Plan above the level of the expense incurred in respect thereof
for the most recent fiscal year ended prior to the date hereof, other than
ordinary course of business increases related to health, life and disability
insurance plans.

   (g) Other than as disclosed in the Company SEC Reports, no employee or
former employee of the Company or any Company Subsidiary will become entitled
to any bonus, retirement, severance, job security or similar benefit or an
enhancement of such benefit (including acceleration of vesting or exercise of
an incentive award) under any Employee Plan as a result of the transactions
contemplated hereby.

   (h) Other than routine claims for benefits and liability for premiums due to
the Pension Benefit Guaranty Corporation, neither the Company nor any Company
Subsidiary or ERISA Affiliate (or any former ERISA Affiliate with respect to
the period in which such entity was an ERISA Affiliate) has incurred any
material liability with respect to any Employee Plan that is currently due and
owing and has not yet been satisfied, including under ERISA, the Code or other
applicable law. No event has occurred and, to the knowledge of the Company,
there exists no condition or set of circumstances (other than the accrual of
benefits under the normal terms of the Employee Plans), that could result in
the imposition of any material liability on the Company or any Company
Subsidiary or ERISA Affiliate (or any former ERISA Affiliate with respect to
the period in

                                      A-16
<PAGE>

which such entity was an ERISA Affiliate) with respect to any Employee Plan,
including under ERISA, the Code or other applicable law with respect to any
Employee Plan.

   Section 3.14 Brokers. Except for the engagement of Donaldson, Lufkin &
Jenrette Securities Corporation, none of the Company or any of the Company
Subsidiaries, or any of their respective officers, directors or employees, has
employed any investment banker, broker, finder or other intermediary or
incurred any liability for any brokerage fees, commissions or finder's fees in
connection with the transactions contemplated by this Agreement.

   Section 3.15 Compliance with Applicable Laws. The Company and the Company
Subsidiaries are in substantial compliance with all laws, regulations and
orders of any Governmental Entity applicable to them, except where the failure
to comply would not have a Material Adverse Effect. The Company and each
Company Subsidiary are in material compliance with, and have obtained, all
licenses, permits, franchises or other governmental authorizations necessary to
the ownership of its properties or to the conduct of its business, except where
the failure to obtain such licenses, permits, franchises or other governmental
authorizations would not have a Material Adverse Effect.

   Section 3.16 Environmental Matters. Except as would not have a Material
Adverse Effect: (i) to the Company's knowledge, no real property currently or
formerly owned or operated by the Company or any current Company Subsidiary is
contaminated with any Hazardous Substances to an extent or in a manner or
condition now requiring remediation under any Environmental Law; (ii) no
judicial or administrative proceeding is pending or, to the knowledge of the
Company, threatened relating to liability for any off-site disposal or
contamination; and (iii) the Company and the Company Subsidiaries have not
received in writing any claims or notices alleging liability under any
Environmental Law. To the Company's knowledge, neither the Company nor any
Company Subsidiary is in violation of any applicable Environmental Law and no
condition or event has occurred with respect to the Company or any Company
Subsidiary that would constitute a violation of such Environmental Law,
excluding in any event such violations, conditions and events that would not
have a Material Adverse Effect.

   Section 3.17 Opinion of Financial Advisor. The Company has received the
written opinion of Donaldson, Lufkin & Jenrette Securities Corporation to the
effect that the Merger Consideration is fair from a financial point of view to
the shareholders of the Company (other than shareholders who are Affiliates of
the Company).

   Section 3.18 No Other Representations. Except as specifically set forth in
this Article III, the Company has not made, and Parent and Merger Sub have not
relied upon, any representations or warranties, whether express or implied.

deliver to Parent a letter identifying all known persons who are, at the time

"affiliates" of the Company under Rule 145 of the Securities Act. The Company
will furnish such information and documents as Parent reasonably may request
for the purpose of reviewing such list. The Company will use its reasonable
best efforts to obtain a written agreement in customary form from each person
who may be so deemed as soon as practicable and, in any event, prior to the
Effective Time.

Company and the Company Subsidiaries as provided in their respective charters,
by-laws or resolutions identified in the Company Disclosure Schedule, in an
agreement between an Indemnified Party and the Company or any of the Company
Subsidiaries (which agreement is identified in the Company Disclosure Schedule)

asserted or made within such six-year period, all rights to indemnification in
respect of any such claim will continue until final disposition thereof.

   (b) Parent and the Surviving Corporation jointly and severally agree to
indemnify all Indemnified Parties to the fullest extent permitted by applicable
law with respect to all acts and omissions arising out of such individuals'
services as officers, directors, employees or agents of the Company or any
Company Subsidiary or as trustees or fiduciaries of any plan for the benefit of
employees, or otherwise on behalf of, the Company or any Company Subsidiary,
occurring at or prior to the Effective Time, including the transactions
contemplated by this Agreement. In the event any Indemnified Party is or
becomes involved in any capacity in any action, proceeding or investigation in
connection with any matter occurring at or prior to the Effective Time, Parent
will pay as incurred such Indemnified Party's legal and other expenses
(including the cost of any investigation and preparation) incurred in

Effective Time, it shall, or shall cause the Surviving Corporation to, provide
Employee Benefit Arrangements for the benefit of the employees and former
employees of the Company and its Subsidiaries, that in the aggregate are not
materially less favorable than the Employee Benefit Arrangements in effect
immediately prior to the Effective Time that are applicable to such employees
or former employees, provided, however, that Parent, at its sole option, may
provide Employee Benefit Arrangements to the employees and former employees of
the Company and the Company Subsidiaries which, in the aggregate, are no less
favorable than those applicable to similarly situated employees of Parent.
Parent will take all actions required so that each employee of the Company or
any Company Subsidiary as of the Effective Time will receive credit for
eligibility and vesting purposes for his or her service with the Company or any
Company Subsidiary prior to the Effective Time under any Employee Benefit
Arrangements established, maintained, continued or made available by Parent in
which any such employee is eligible to participate.

   (c) Nothing in this Section 6.02 shall be construed to limit the ability of
Parent to terminate the employment of any employee or to review Employee
Benefit Arrangements from time to time and make such changes as it deems
appropriate, subject to the terms of such Employee Benefit Arrangements.

   Section 6.03 Listing; Registration. Prior to the Effective Time, Parent will
use its best efforts to cause the Parent Common Stock to be issued in the
Merger to be approved for listing on the Nasdaq National Market, subject only
to notice of official issuance.

   Section 6.04 Conduct of Parent. From the date hereof until the Effective
Time, Parent will not, and will cause the Parent Subsidiaries not to, take or
agree to take any action that would (i) interfere with the consummation of the
transactions contemplated hereby or make such consummation more difficult or

representation or warranty of Parent or Merger Sub contained in this Agreement
untrue or incorrect as of the date when made or as of the Closing Date or (iii)

herein provided, each of the parties will use its reasonable best efforts to
take, or cause to be taken, all action, and to do, or cause to be done and to
assist and cooperate with the other parties in doing, as promptly as
practicable, all things necessary, appropriate or advisable under applicable
laws and regulations or otherwise to ensure that the conditions set forth in
Article VIII are satisfied and to consummate and make effective the
transactions contemplated by this Agreement. If at any time after the Effective
Time any further action is reasonably necessary or desirable to carry out the
purposes of this Agreement, including the execution of additional instruments,
the proper officers and directors of each party will take all such action.

   Section 7.02. Registration Statement. Parent promptly will prepare and file
the Registration Statement with the SEC under the Securities Act, and will use
its reasonable best efforts to cause the Registration

                                      A-25
<PAGE>

Statement to be declared effective by the SEC as promptly as practicable.
Parent promptly will take any action required to be taken under foreign or
state securities or Blue Sky laws in connection with the issuance of Parent
Common Stock in connection with the Merger.

action necessary in accordance with the NJBCA and its certificate of
incorporation and by-laws to call, give notice of and hold a meeting (the
"Company Shareholder Meeting") of its shareholders to consider and vote upon
the approval and adoption of this Agreement and the Merger and for such other
purposes as may be necessary or desirable.

   (b) Promptly after the date hereof, Parent and the Company will prepare a
proxy statement pertaining to the Merger to be distributed to the holders of
the Company Common Stock, which will constitute the prospectus included in the
Registration Statement (the "Proxy Statement/Prospectus"). The Company Board

shareholders in connection therewith, and the Company will include such

comments from the SEC and of any request by the SEC for amendments or
supplements to the Registration Statement or the Proxy Statement/Prospectus or
for additional information, and promptly will supply each other with copies of
all correspondence between the parties and the SEC with respect thereto. If, at
any time prior to the Company Shareholder Meeting, any event should occur
relating to or affecting the Company, Parent or Merger Sub, or to their
respective Subsidiaries, officers or directors, which event should be described
in an amendment or supplement to the Registration Statement or the Proxy
Statement/Prospectus, the parties promptly will inform each other and cooperate
in preparing, filing and having declared effective or clearing with the SEC
and, if required by applicable state securities laws, distributing to the
Company's shareholders such amendment or supplement.

   Section 7.04 Consents. Each of the parties will use its reasonable best
efforts to obtain as promptly as practicable all consents (including from any
Franchising Authority and in connection with the change in control of the
holder of the Franchises of the Company and the Company Subsidiaries), waivers,
approvals, authorizations or permits of any Governmental Entity or any other
Person required in connection with, and waivers of any Violations that may be
caused by, the consummation of the transactions contemplated by this Agreement.

   Section 7.05 Public Announcements. Neither Parent nor the Company will issue
any press release or make any other public announcement concerning this
Agreement, the Merger or the transactions contemplated hereby without the prior
consent of the other, except that either party may make such public disclosure
that it believes in good faith to be required by law (in which event such party
will notify the other party prior to making such disclosure).

   Section 7.06 Notification of Certain Matters. Parent and the Company
promptly will notify the other of: (i) the occurrence or non-occurrence of any
fact or event that would be reasonably likely to cause any (x) representation
or warranty contained in this Agreement to be untrue or inaccurate in any
material respect at any time from the date hereof to the Effective Time or (y)
material covenant, condition or agreement contained in this Agreement not to be
complied with or satisfied in all material respects; and (ii) any failure of
the Company, Parent or Merger Sub to comply with or satisfy in any material
respect any covenant, condition or agreement contained in this Agreement.

   Section 7.07 Antitrust Matters.

   (a) Parent and the Company promptly will complete all documents required to
be filed with the Federal Trade Commission and the Department of Justice in
order to comply with the HSR Act and, together with the Persons who are
required to join in such filings, will file the same with the appropriate
Governmental Entities. Parent and the Company promptly will furnish all
materials thereafter required by any of the Governmental Entities having
jurisdiction over such filings and will take all reasonable actions and file
and use all reasonable efforts to have declared effective or approved all
documents and notifications with any such Governmental Entities, as may be
required under the HSR Act for the consummation of the Merger.

   (b) Parent will use its best efforts to resolve such objections, if any, as
may be asserted with respect to the transactions contemplated by this Agreement
under any antitrust, competition or trade regulatory laws, rules or regulations
of any domestic or foreign Governmental Entity ("Antitrust Laws"). If any suit
is threatened or instituted challenging the Merger as violating any Antitrust
Law, Parent will take such action (including opposing by all appropriate legal
means any claim raised in any such suit and, if necessary, agreeing to hold
separate or to divest any of the businesses, product lines or assets of Parent
or any of its Affiliates controlled by it or of any of its Subsidiaries or
Affiliates) as may be required (i) by the applicable Governmental Entity in
order to resolve such objections as such Governmental Entity may have to such
transactions under such Antitrust Law or (ii) by any domestic or foreign court
or similar tribunal, in any suit brought by a private party or governmental
authority challenging the Merger as violating any Antitrust Law, in order to
avoid the entry of, or to effect the dissolution of, any injunction, temporary
restraining order or other order that has the effect of preventing the
consummation of the Merger. The entry by a court, in any suit brought by a
private party or Governmental Entity challenging the Merger as violating any
Antitrust Law, of an order or decree permitting the Merger but requiring that
any of the businesses or assets of Parent or any Parent Subsidiary or
Affiliates be divested or held separate by Parent, or that would otherwise
limit Parent's freedom of action with respect to, or its ability to retain, the
Company and the Company Subsidiaries or any portion thereof or any of Parent's
or its Subsidiaries' or Affiliates' other assets or businesses, will not be
deemed a failure to satisfy the conditions specified in Section 8.01(d).

   (c) Each party promptly will inform the other of any material communication
from the Federal Trade Commission, the Department of Justice, the FCC or any
other domestic or foreign Governmental Entity regarding any of the transactions
contemplated by this Agreement. If any party or any Affiliate thereof receives
a request for additional information or documentary material from any such
government or authority with respect to the transactions contemplated by this
Agreement, such party will endeavor in good faith to make, as soon as
reasonably practicable and after consultation with the other party, an
appropriate response to such request. Parent promptly will advise the Company
in respect of any understandings, undertakings or agreements which Parent
proposes to make or enter into with the Federal Trade Commission, the
Department of Justice, the FCC or any other domestic or foreign Governmental
Entity in connection with the transactions contemplated by this Agreement.

   Section 7.08 Access to Information. From the date hereof until the Effective
Time, Parent and the Company will, and will cause each of their Subsidiaries
to: (i) give the other party and its counsel, financial advisors, auditors and
other authorized representatives reasonable access during normal business hours
to the offices, properties, books and records of such party and its
Subsidiaries as the other party reasonably may request, and furnish the other
party with such financial and operating data and other information as the other
party reasonably may request; and (ii) instruct such parties' employees,
counsel and financial advisors to cooperate with the other party in their
investigation of the business of such party and its Subsidiaries.

   Section 7.09 Tax-free Reorganization. Prior to the Effective Time, each
party will use its best efforts to cause the Merger to qualify as a
reorganization within the meaning of Section 368 of the Code, and will not take
any action reasonably likely to cause the Merger not to qualify as such a
reorganization.

   Section 7.10 Dissenting Shareholders. Notwithstanding anything in this
Agreement to the contrary, but only to the extent required by the NJBCA, shares
of the Company Common Stock that are issued and

                                      A-27
<PAGE>

outstanding immediately prior to the Effective Time and are held by holders of
shares of Company Common Stock who comply with all the provisions of the NJBCA
concerning the right of holders of shares of Company Common Stock to dissent
from the Merger and require appraisal of their shares ("Dissenting
Shareholders") shall not be converted into the right to receive the Merger
Consideration but shall become the right to receive such consideration as may
be determined to be due such Dissenting Shareholder pursuant to the laws of the
State of New Jersey; provided, however, that (i) if any Dissenting Shareholder
shall subsequently withdraw his or her demand for appraisal or fail to
establish or perfect or otherwise lose his or her appraisal rights as provided
by applicable law, then such Dissenting Shareholder or Shareholders, as the
case may be, shall forfeit the right to appraisal of such shares of Company
Common Stock and such shares of Company Common Stock shall thereupon be deemed
to have been converted into the right to receive, as of the Effective Time, (x)
with respect to each share of Class A Company Common Stock held by Dissenting
Shareholders, $9.16426528 in cash and 0.61222732 shares of Parent Common Stock,
without interest, and (y) with respect to each share of Class B Company Common
Stock held by Dissenting Shareholders, $11.81417001 in cash and 0.63595483
shares of Parent Common Stock, without interest (it being understood that
nothing herein shall be interpreted to give the Class B Shareholders the right
to become Dissenting Shareholders without violating the Class B Voting
Agreement). The Company shall give Parent (A) prompt notice of any written
demands for appraisal of shares of Company Common Stock, withdrawals of demands
for appraisal and any other related instruments received by the Company, and
(B) the opportunity to direct all negotiations and proceedings with respect to
any such demands for appraisal. The Company will not, except with the prior
written consent of Parent, voluntarily make any payment with respect to any
demands for appraisal or settle, offer or otherwise negotiate to settle any
demand.

   Section 7.11 Registration Rights. From and after the Effective Time, Parent
agrees to grant the Class B Shareholders and their permitted assignees and
transferees registration rights pursuant to a Registration Rights Agreement to
be entered into promptly after the date hereof. Parent agrees that the
registration rights shall include two demand registration rights and unlimited
piggy-back rights subject to any existing registration rights agreements of
Parent at the expense of Parent with standard indemnification provisions. In
addition, the Registration Rights Agreement will provide for the Class B
Shareholders to be entitled to proportionate tag-along rights upon any sale or
other transfer for value of shares of Parent Common Stock by members of the
Rigas family.

   Section 7.12 Board of Directors. Parent agrees that from and after the
Effective Time, for so long as the Class B Shareholders and the Century
Permitted Assignees and Transferees (as defined below) own at least 10% of the
outstanding Common Stock of Parent (the "10% Requirement"), the Class B
Shareholders and the Century Permitted Assignees and Transferees shall be
entitled to nominate up to three members of Parent's board of directors (the
"Century Designees"). In the event any Century Designee ceases to serve as a
Director of Parent, whether as a result of his resignation, removal or
otherwise, his or her successor shall be named by the Century Designee who at
such time holds the most shares of Parent Common Stock, subject to approval by
the Parent, which approval will not be unreasonably withheld or delayed, to
serve until the next annual meeting of shareholders of Parent. Prior to the
Effective Time, Parent agrees to take all such action as is necessary so that
from and after the Effective Time, so long as the 10% Requirement is satisfied,
the Parent Board of Directors shall include Leonard Tow, Scott Schneider and
Bernard Gallagher or such other persons designated by Leonard Tow which are
reasonably acceptable to Parent. "Century Permitted Assignees and Transferees"
shall mean a person or entity (i) to whom Parent Common Stock has been
transferred from a Class B Shareholder or another Century Permitted Assignee
and Transferee and (ii) who or which is an affiliate, immediate family member
or descendant, in each case of Leonard Tow, or a trust created for the benefit
of Leonard Tow or an affiliate, immediate family member or descendant, in each
case of Leonard Tow.

   Section 7.13 Citizens Joint Venture. At the Effective Time, Parent will
purchase from Citizens Cable Company or its Affiliates the 50% interest owned
by Citizens Cable Company in Citizens-Century Cable Television Venture for a
purchase price to be mutually agreed upon by Parent, the Company and Citizens
Cable Company.

obtained prior to the date referred to in Section 9.01(d) cover more than 50%

March 5, 1999

Adelphia Communications Corporation
Main at Water Street
Coudersport, PA 16915

Attention: Board of Directors

Gentlemen:

   Daniels & Associates, L.P. ("Daniels") has been retained by Adelphia
Communications Corporation (together with its affiliates, "Adelphia") to render
to its Board of Directors an opinion as to the fairness, from a financial point
of view, of a proposed "Transaction" to the shareholders of Adelphia's common
stock. Daniels has been advised that Adelphia has executed a definitive
agreement for the plan of merger of Century Communications Corp. ("Century")
with Adelphia. We understand that pursuant to the Merger Agreement (defined
hereafter), Century's Class A common stockholders will receive cash of $9.16
per share and 0.6122 shares of Adelphia Class A Common Stock (for a total
market value of the consideration of $44.14 per share based on the closing
price on March 4, 1999 of $57.125) for each share of Century Class A Common
Stock held, and Century's Class B Common stockholders will receive $11.81 in
cash and 0.6360 shares of Adelphia Class A Common Stock (for a total market
value of the consideration of $48.14 per share based on the closing price on
March 4, 1999) for each share of Century Class B Common Stock held. The
aggregate Common Stock value of the Transaction is $3.6 billion.

   In addition to the Common Stock value, it is further understood that
Adelphia will assume certain debt obligations amounting to $1.7 billion (net of
cash and cash equivalents) and certain minority interest value (net of certain
other assets) amounting to $0.5 billion. Total consideration for the Company in
the Transaction is $5.7 billion (together the "Transaction")

   You have asked us to render an opinion as to the fairness, from a financial
point of view, of the Transaction to the common shareholders of Adelphia.

   In arriving at the opinion set forth below, we have, among other things,
done the following:

  (1) Reviewed the Agreement and Plan of Merger, dated March 5, 1999, by and
      among Adelphia Communications Corporation, Adelphia Acquisition
      Subsidiary Inc. and Century Communications Corp. (the "Merger
      Agreement");

  (2) Reviewed Adelphia's annual report on Form 10-K and related financial
      information for the fiscal year ended March 31, 1998, and Adelphia's
      unaudited quarterly reports on From 10-Q and related financial
      information for the three-month periods ended June 30, 1998, September
      30, 1998 and December 31, 1998;

  (3) Reviewed Century's annual report on Form 10-K and related audited
      financial information for the fiscal year ended May 31, 1998, and
      Century's unaudited quarterly reports on Form 10-Q and related
      financial information for the three-month periods ended August 31, 1998
      and November 30, 1998. We also reviewed the Century Communications
      Corporation Confidential Information Memorandum, dated January 1999,
      prepared by Donaldson, Lufkin & Jenrette;

  (4) Reviewed certain information relating to the business, earnings, cash
      flow, assets and prospects of Adelphia and Century, furnished to us by
      Adelphia and Century;

  (5) Conducted discussions with members of senior management of Adelphia and
      Century regarding the business and prospects of Adelphia and Century;

  (6) Compared the results of operations of the assets of Century with those
      of certain companies which we deemed to be reasonably similar to
      Century;

                                      B-1
<PAGE>

  (7) Compared the proposed financial terms of the Transaction contemplated
      by the Merger Agreement with the terms of certain other mergers and
      acquisitions which we deemed to be reasonably similar to the
      Transaction; and

  (8) Reviewed such other financial studies and analyses and performed such
      other investigations and took into account such other matters as we
      deemed necessary for purposes of our opinion.

   In preparing our opinion, we have relied on the accuracy and completeness of
all financial and other information supplied or otherwise made available to us
by Adelphia and Century, and we have not independently verified such
information. This opinion does not address the relative merits of the
Transaction as compared with any other transactions or proposed transactions
submitted to Adelphia or discussed by the Board of Directors of Adelphia as
alternatives to the Transaction. This opinion is based on market, economic,
financial and other conditions as they existed and could be evaluated as of
this date.

   Simultaneous with our engagement to render a fairness opinion to Adelphia,
we are also currently engaged to advise Adelphia with regards to the
Transaction. We are also in active discussions with Adelphia regarding a number
of potential mergers with, and/or acquisitions and trades of cable properties
which, if consummated, will result in Daniels receiving one or more transaction
fees. In addition, in the past, Daniels has advised Adelphia and Century
regarding possible acquisitions, sales and related transactions and has
received fees therefor from Adelphia and Century. We do not believe that any of
these activities affect our ability to render an independent and unbiased
opinion as to the fairness of the proposed Transaction.

   On the basis of and subject to the foregoing, we are of the opinion that, as
of the date of this letter, the proposed Transaction is fair, from a financial
point of view, to Adelphia and the shareholders of its common stock.

Very truly yours,

/s/ Daniels & Associates, L.P.

                                                             As of March 4, 1999

Board of Directors
Century Communications Corp.
50 Locust Avenue
New Canaan, CT 06840

Dear Sirs:

   You have requested our opinion as to the fairness from a financial point of
view to the holders of Class A capital stock, par value $0.01 per share (the
"Class A Common Stock") of Century Communications Corp. (the "Company") (other
than shareholders who are affiliates of the Company) of the consideration to be
received by such holders pursuant to the terms of the Agreement and Plan of
Merger dated as of March 5, 1999, among Adelphia Communications Corporation
("Parent"), Adelphia Acquisition Subsidiary, Inc., a direct wholly-owned
subsidiary of Parent ("Merger Sub"), and the Company (the "Agreement").

   Pursuant to the Agreement, each share of Class A Common Stock will be
converted into the right to receive $9.16426528 in cash and 0.61222732 shares
of Class A common stock (the "Parent Common Stock"), par value $0.01 per share,
of Parent (collectively, the "Class A Merger Consideration"), and each of share
of Class B common stock, par value $0.01 per share (the "Class B Common Stock,"
and together with the Class A Common Stock, the "Common Stock"), of the Company
will be converted into the right to receive $11.81417001 in cash and 0.63595483
shares of Parent Common Stock.

   In arriving at our opinion, we have reviewed the draft dated March 4, 1999
of the Agreement and the Schedules thereto. We also have reviewed financial and
other information that was publicly available or furnished to us by the Company
and Parent, including information provided during discussions with management
of the Company and Parent. Included in the information provided to us by the
Company were financial and operations forecasts for the fiscal periods ending
May 31, 1999 and May 31, 2000. In addition, we have compared certain financial
and securities data of the Company and Parent with various other companies
whose securities are traded in public markets, reviewed the historical stock
prices and trading volumes of the Class A Common Stock and Parent Common Stock,
reviewed prices and premiums paid in certain other business combinations and
conducted such other financial studies, analyses and investigations as we
deemed appropriate for purposes of this opinion.

   In rendering our opinion, we have relied upon and assumed the accuracy,
completeness and fairness of all the financial and other information that was
available to us from public sources, that was provided to us by the Company,
Parent or their respective representatives, or that was otherwise reviewed by
us. With respect to the financial analyses and forecasts supplied to us by the
Company, we have assumed that they have been reasonably prepared on the basis
reflecting reasonable estimates and judgments of the management of the Company.
As you are aware, Parent did not make available to us its projections of
expected future performance. We have assumed that no requisite regulatory
consent or approval for the Merger will impose any condition, including any
divestiture requirement, that will have a material adverse effect on the
contemplated benefits of the Merger.

   We have not assumed any responsibility for making an independent evaluation
of the Company's or Parent's assets or liabilities or for making any
independent verification of any of the information reviewed by us. We have
relied as to certain legal matters relating to the Agreement and transactions
contemplated thereby on advice of counsel to the Company.


                                      C-1

   Our opinion is necessarily based on economic, market, financial and other
conditions as they exist on, and on the information made available to us, as of
the date of this letter. It should be understood that, although subsequent
developments may affect this opinion, we do not have any obligation to update,
revise or reaffirm this opinion. We are expressing no opinion herein as to the
relative merits of the proposed transaction and any other business strategies
being considered by the Company's Board of Directors, nor does it address the
Board's decision to proceed with the proposed transaction. Our opinion does not
constitute a recommendation to any stockholder as to how such stockholder
should vote on the proposed transaction. We are expressing no opinion as to the
prices at which the Parent Common Stock will actually trade at any time.

   Donaldson, Lufkin & Jenrette Securities Corporation ("DLJ"), as part of its
investment banking services, is regularly engaged in the valuation of
businesses and securities in connection with mergers, acquisitions,
underwritings, sales and distributions of listed and unlisted securities,
private placements and valuations for estate, corporate and other purposes. DLJ
has performed investment banking and other services for the Company in the past
and has been compensated for such services. Specifically, we acted as the
Company's financial advisor in connection with the merger of Centennial
Cellular Corp., a subsidiary of the Company, with CCW Acquisition Corporation
for which we received usual and customary fees. DLJ has also performed
investment banking and other services for Parent in the past and has been
compensated for such services.

   Based upon the foregoing and such other factors as we deem relevant, we are
of the opinion that the Class A Merger Consideration to be received by the
holders of Class A Common Stock pursuant to the Agreement (other than
stockholders who are affiliates of the Company) is fair to such holders from a

                 CHAPTER 11. RIGHTS OF DISSENTING SHAREHOLDERS

   14A:11-1 RIGHT OF SHAREHOLDERS TO DISSENT.--(1) Any shareholder of a
domestic corporation shall have the right to dissent from any of the following
corporate actions

     (a) Any plan of merger or consolidation to which the corporation is a
  party, provided that, unless the certificate of incorporation otherwise
  provides

       (i) a shareholder shall not have the right to dissent from any plan
    of merger or consolidation with respect to shares

         (A) of a class or series which is listed on a national securities
      exchange or is held of record by not less than 1,000 holders on the
      record date fixed to determine the shareholders entitled to vote
      upon the plan of merger or consolidation; or

         (B) for which, pursuant to the plan of merger or consolidation,
      he will receive (x) cash, (y) shares, obligations or other
      securities which, upon consummation of the merger or consolidation,
      will either be listed on a national securities exchange or held of
      record by not less than 1,000 holders, or (z) cash and such
      securities;

       (ii) a shareholder of a surviving corporation shall not have the
    right to dissent from a plan of merger, if the merger did not require
    for its approval the vote of such shareholders as provided in section
    14A:10-5.1 or in subsection 14A:10-3(4), 14A:10-7(2) or 14A:10-7(4); or

     (b) Any sale, lease, exchange or other disposition of all or
  substantially all of the assets of a corporation not in the usual or
  regular course of business as conducted by such corporation, other than a
  transfer pursuant to subsection (4) of N.J.S. 14A:10-11, provided that,
  unless the certificate of incorporation otherwise provides, the shareholder
  shall not have the right to dissent

       (i) with respect to shares of a class or series which, at the record
    date fixed to determine the shareholders entitled to vote upon such
    transaction, is listed on a national securities exchange or is held of
    record by not less than 1,000 holders; or

       (ii) from a transaction pursuant to a plan of dissolution of the
    corporation which provides for distribution of substantially all of its
    net assets to shareholders in accordance with their respective
    interests within one year after the date of such transaction, where
    such transaction is wholly for

         (A) cash; or

         (B) shares, obligations or other securities which, upon
      consummation or the plan of dissolution will either be listed on a
      national securities exchange or held of record by not less than
      1,000 holders; or

         (C) cash and such securities; or

       (iii) from a sale pursuant to an order of a court having
    jurisdiction.

   (2) Any shareholder of a domestic corporation shall have the right to
dissent with respect to any shares owned by him which are to be acquired
pursuant to section 14A:10-9.

   (3) A shareholder may not dissent as to less than all of the shares owned
beneficially by him and with respect to which a right of dissent exists. A
nominee or fiduciary may not dissent on behalf of any beneficial owner as to
less than all of the shares of such owner with respect to which the right of
dissent exists.

                                      D-1

   (4) A corporation may provide in its certificate of incorporation that
holders of all of its shares, or of a particular class or series thereof, shall
have the right to dissent from specified corporate actions in addition to those
enumerated in subsection 14A:11-1(1), in which case the exercise of such right
of dissent shall be governed by the provisions of this Chapter. (Last amended
by Ch. 279, L. '95, eff. 12-15-95.)

   14A:11-2 NOTICE OF DISSENT; DEMAND FOR PAYMENT; ENDORSEMENT OF
CERTIFICATES.--(1) Whenever a vote is to be taken, either at a meeting of
shareholders or upon written consents in lieu of a meeting pursuant to section
14A:5-6, upon a proposed corporate action from which a shareholder may dissent
under section 14A:11-1, any shareholder electing to dissent from such action
shall file with the corporation before the taking of the vote of the
shareholders on such corporate action, or within the time specified in
paragraphs 14A:5-6(2)(b) or 14A:5-6(2)(c), as the case may be, if no meeting of
shareholders is to be held, a written notice of such dissent stating that he
intends to demand payment for his shares if the action is taken.

   (2) Within 10 days after the date on which such corporate action takes
effect, the corporation, or, in the case of a merger or consolidation, the
surviving or new corporation, shall give written notice of the effective date
of such corporate action, by certified mail to each shareholder who filed
written notice of dissent pursuant to subsection 14A:11-2(1), except any who
voted for or consented in writing to the proposed action.

   (3) Within 20 days after the mailing of such notice, any shareholder to whom
the corporation was required to give such notice and who has filed a written
notice of dissent pursuant to this section may make written demand on the
corporation, or, in the case of a merger or consolidation, on the surviving or
new corporation, for the payment of the fair value of his shares.

   (4) Whenever a corporation is to be merged pursuant to/1/ section 14A:10-
5.1 or subsection 14A:10-7(4) and shareholder approval is not required under/2/
subsections 14A:10-5.1(5) and 14A:10-5.1(6), a shareholder who has the right to
dissent pursuant to section 14A:11-1 may, not later than 20 days after a copy
or summary of the plan of such merger and the statement required by/3/
subsection 14A:10-5.1(2) is mailed to such shareholder, make written demand on
the corporation or on the surviving corporation, for the payment of the fair
value of his shares.

   (5) Whenever all the shares, or all the shares of a class or series, are to
be acquired by another corporation pursuant to section 14A:10-9, a shareholder
of the corporation whose shares are to be acquired may, not later than 20 days
after the mailing of notice by the acquiring corporation pursuant to paragraph
14A:10-9(3)(b), make written demand on the acquiring corporation for the
payment of the fair value of his shares.

   (6) Not later than 20 days after demanding payment for his shares pursuant
to this section, the shareholder shall submit the certificate or certificates
representing his shares to the corporation upon which such demand has been made
for notation thereon that such demand has been made, whereupon such certificate
or certificates shall be returned to him. If shares represented by a
certificate on which notation has been made shall be transferred, each new
certificate issued therefor shall bear similar notation, together with the name
of the original dissenting holder of such shares, and a transferee of such
shares shall acquire by such transfer no rights in the corporation other than
those which the original dissenting shareholder had after making a demand for
payment of the fair value thereof.

   (7) Every notice or other communication required to be given or made by a
corporation to any shareholder pursuant to this Chapter shall inform such
shareholder of all dates prior to which action must be taken by such
shareholder in order to perfect his rights as a dissenting shareholder under
this Chapter. (Last amended by Ch. 94, L. '88, eff. 12-1-88.)

<PAGE>

   14A:11-3 "DISSENTING SHAREHOLDER" DEFINED; DATE FOR DETERMINATION OF FAIR
VALUE.--(1) A shareholder who has made demand for the payment of his shares in
the manner prescribed by subsection 14A:11-2(3), 14A:11-2(4) or 14A:11-2(5) is
hereafter in this Chapter referred to as a "dissenting shareholder".

   (2) Upon making such demand, the dissenting shareholder shall cease to have
any of the rights of a shareholder except the right to be paid the fair value
of his shares and any other rights of a dissenting shareholder under this
Chapter.

   (3) "Fair value" as used in this Chapter shall be determined

     (a) As of the day prior to the day of the meeting of shareholders at
  which the proposed action was approved or as of the day prior to the day
  specified by the corporation for the tabulation of consents to such action
  if no meeting of shareholders was held; or

     (b) In the case of a merger pursuant to /1/section 14A:10-5.1(1) or
  subsection 14A:10-7(4) in which shareholder approval is not required, as of
  the day prior to the day on which the board of directors approved the plan
  of merger; or

     (c) In the case of an acquisition of all the shares or all the shares of
  a class or series by another corporation pursuant to section 14A:10-9, as
  of the day prior to the day on which the board of directors of the
  acquiring corporation authorized the acquisition, or, if a shareholder vote
  was taken pursuant to section 14A:10-12, as of the day provided in
  paragraph 14A:11- 3(3)(a).

     In all cases, "fair value" shall exclude any appreciation or
  depreciation resulting from the proposed action. (Last amended by Ch. 94,
  L. '88, eff. 12-1- 88.)

   14A:11-4 TERMINATION OF RIGHT OF SHAREHOLDER TO BE PAID THE FAIR VALUE OF
HIS SHARES.--(1) The right of a dissenting shareholder to be paid the fair
value of his shares under this Chapter shall cease if

     (a) he has failed to present his certificates for notation as provided
  by subsection 14A:11-2(6), unless a court having jurisdiction, for good and
  sufficient cause shown, shall otherwise direct;

     (b) his demand for payment is withdrawn with the written consent of the
  corporation;

     (c) the fair value of the shares is not agreed upon as provided in this
  Chapter and no action for the determination of fair value by the Superior
  Court is commenced within the time provided in this Chapter;

     (d) the Superior Court determines that the shareholder is not entitled
  to payment for his shares;

     (e) the proposed corporate action is abandoned or rescinded; or

     (f) a court having jurisdiction permanently enjoins or sets aside the
  corporate action.

   (2) In any case provided for in subsection 14A:11-4(1), the rights of the
dissenting shareholder as a shareholder shall be reinstated as of the date of
the making of a demand for payment pursuant to subsection 14A:11-2(3), 14A:11-
2(4) or 14A:11-2(5) without prejudice to any corporate action which has taken
place during the interim period. In such event, he shall be entitled to any
intervening preemptive rights and the right to payment of any intervening
dividend or other distribution, or, if any such rights have expired or any such
dividend or distribution other than in cash has been completed, in lieu
thereof, at the election of the board, the fair value thereof in cash as of the
time of such expiration or completion.

<PAGE>

   14A:11-5 RIGHTS OF DISSENTING SHAREHOLDERS.--(1) A dissenting shareholder
may not withdraw his demand for payment of the fair value of his shares without
the written consent of the corporation.

   (2) The enforcement by a dissenting shareholder of his right to receive
payment for his shares shall exclude the enforcement by such dissenting
shareholder of any other right to which he might otherwise be entitled by
virtue of share ownership, except as provided in subsection 14A:11-4(2) and
except that this subsection shall not exclude the right of such dissenting
shareholder to bring or maintain an appropriate action to obtain relief on the
ground that such corporate action will be or is ultra vires, unlawful or
fraudulent as to such dissenting shareholder.

   14A:11-6 DETERMINATION OF FAIR VALUE BY AGREEMENT.--(1) Not later than 10
days after the expiration of the period within which shareholders may make
written demand to be paid the fair value of their shares, the corporation upon
which such demand has been made pursuant to subsection 14A:11-2(3), 14A:11-2(4)
or 14A:11-2(5) shall mail to each dissenting shareholder the balance sheet and
the surplus statement of the corporation whose shares he holds, as of the
latest available date which shall not be earlier than 12 months prior to the
making of such offer and a profit and loss statement or statements for not less
than a 12- month period ended on the date of such balance sheet or, if the
corporation was not in existence for such 12-month period, for the portion
thereof during which it was in existence. The corporation may accompany such
mailing with a written offer to pay each dissenting shareholder for his shares
at a specified price deemed by such corporation to be the fair value thereof.
Such offer shall be made at the same price per share to all dissenting
shareholders of the same class, or, if divided into series, of the same series.

   (2) If, not later than 30 days after the expiration of the 10-day period
limited by subsection 14A:11-6(1), the fair value of the shares is agreed upon
between any dissenting shareholder and the corporation, payment therefor shall
be made/1/ upon surrender of the certificate or certificates representing such
shares. (Last amended by Ch. 366, L. '73, eff. 5-1-74.)

   14A:11-7 PROCEDURE ON FAILURE TO AGREE UPON FAIR VALUE; COMMENCEMENT OF
ACTION TO DETERMINE FAIR VALUE.--(1) If the fair value of the shares is not
agreed upon within the 30-day period limited by subsection 14A:11-6(2), the
dissenting shareholder may serve upon the corporation upon which such demand
has been made pursuant to subsection 14A-11-2(3), 14A:11-2(4) or 14A:11-2(5) a
written demand that it commence an action in the Superior Court for the
determination of the fair value of the shares. Such demand shall be served not
later than 30 days after the expiration of the 30-day period so limited and
such action shall be commenced by the corporation not later than 30 days after
receipt by the corporation of such demand, but nothing herein shall prevent the
corporation from commencing such action at any earlier time.

   (2) If a corporation fails to commence the action as provided in subsection
14A:11-7(1), a dissenting shareholder may do so in the name of the corporation,
not later than 60 days after the expiration of the time limited by subsection
14A:11-7(1) in which the corporation may commence such an action.

   14A:11-8 ACTION TO DETERMINE FAIR VALUE; JURISDICTION OF COURT; APPOINTMENT
OF APPRAISER.-- In any action to determine the fair value of shares pursuant to
this Chapter:

     (a) The Superior Court shall have jurisdiction and may proceed in the
  action in a summary manner or otherwise;

     (b) All dissenting shareholders, wherever residing, except those who
  have agreed with the corporation upon the price to be paid for their
  shares, shall be made parties thereto as an action against their shares
  quasi in rem;

                                      D-4
<PAGE>

     (c) The court in its discretion may appoint an appraiser to receive
  evidence and report to the court on the question of fair value, who shall
  have such power and authority as shall be specified in the order of his
  appointment; and

     (d) The court shall render judgment against the corporation and in favor
  of each shareholder who is a party to the action for the amount of the fair
  value of his shares.

   14A:11-9 JUDGMENT IN ACTION TO DETERMINE FAIR VALUE.--(1) A judgment for the
payment of the fair value of shares shall be payable upon surrender to the
corporation of the certificate or certificates representing such shares.

   (2) The judgment shall include an allowance for interest at such rate as the
court finds to be equitable, from the date of the dissenting shareholder's
demand for payment under subsection 14A:11-2(3), 14A:11-2(4) or 14A:11-2(5) to
the day of payment. If the court finds that the refusal of any dissenting
shareholder to accept any offer of payment, made by the corporation under
section 14A:11-6, was arbitrary, vexatious or otherwise not in good faith, no
interest shall be allowed to him.

   14A:11-10 COSTS AND EXPENSES OF ACTION.-- The costs and expenses of bringing
an action pursuant to section 14A:11-8 shall be determined by the court and
shall be apportioned and assessed as the court may find equitable upon the
parties or any of them. Such expenses shall include reasonable compensation for
and reasonable expenses of the appraiser, if any, but shall exclude the fees
and expenses of counsel for and experts employed by any party; but if the court
finds that the offer of payment made by the corporation under section 14A:11-6
was not made in good faith, or if no such offer was made, the court in its
discretion may award to any dissenting shareholder who is a party to the action
reasonable fees and expenses of his counsel and of any experts employed by the
dissenting shareholder.

   14A:11-11 DISPOSITION OF SHARES ACQUIRED BY CORPORATION.--(1) The shares of
a dissenting shareholder in a transaction described in subsection 14A:11-11 (1)
shall become reacquired by the corporation which issued them or by the
surviving corporation, as the case may be, upon the payment of the fair value
shares.

   (2) [Intentionally Omitted]

   (3) In an acquisition of shares pursuant to section 14A:10-9 or section
14A:10-13, the shares of a dissenting shareholder shall become the property of
the acquiring corporation upon the payment by the acquiring corporation of the
fair value of such shares. Such payment may be made, with the consent of the
acquiring corporation, by the corporation which issued the shares, in which
case the shares so paid for shall become reacquired by the corporation which
issued them and shall be canceled. (Last amended by Ch. 279, l. '95, eff. 12-
15-95.)

                     INFORMATION NOT REQUIRED IN PROSPECTUS

Item 20. Indemnification of Directors and Officers

  Section 145 of the Delaware General Corporation Law provides in general that
a corporation may indemnify its directors, officers, employees or agents
against expenditures (including judgments, fines, amounts paid in settlement
and attorneys' fees) made by them in connection with certain lawsuits to which
they may be made parties by reason of their being directors, officers,
employees or agents and shall so indemnify such persons against expenses
(including attorneys' fees) if they have been successful on the merits or
otherwise. The bylaws of Adelphia provide for indemnification of the officers
and directors of Adelphia to the full extent permissible under Delaware law.

  Adelphia's Certificate of Incorporation also provides, pursuant to Section
102(b)(7) of the Delaware General Corporation Law, that directors of Adelphia
shall not be personally liable to Adelphia or its stockholders for monetary
damages for breach of fiduciary duty as a director for acts or omissions after
July 1, 1986, provided that directors shall nonetheless be liable for breaches
of the duty of loyalty, bad faith, intentional misconduct, knowing violations
of law, unlawful distributions to stockholders, or transactions from which a
director derived an improper personal benefit.

   (b) Financial Statement Schedule

   Schedules are omitted because they either are not required or are not
applicable or because equivalent information has been included in the financial
statements, the notes thereto or elsewhere herein.

ITEM 22. UNDERTAKINGS

   (a) The undersigned Registrant hereby undertakes:

     (1) That, for purposes of determining any liability under the Securities
  Act of 1933, each filing of the registrant's annual report pursuant to
  section 13(a) or section 15(d) of the Securities Exchange Act of 1934 (and,
  where applicable, each filing of an employee benefit plan's annual report
  pursuant to section 15(d) of the Securities Exchange Act of 1934) that is
  incorporated by reference in the registration statement shall be deemed to
  be a new registration statement relating to the securities offered therein,
  and the offering of such securities at that time shall be deemed to be the
  initial bona fide offering thereof.

     (2) That prior to any public reoffering of the securities registered
  hereunder through use of a prospectus which is a part of this registration
  statement, by any person or party who is deemed to be an underwriter within
  the meaning of Rule 145(c), the issuer undertakes that such reoffering
  prospectus will contain the information called for by the applicable
  registration form with respect to reofferings by persons who may be deemed
  underwriters, in addition to the information called for by the other Items
  of the applicable form.

     (3) That every prospectus (i) that is filed pursuant to paragraph 2
  immediately preceding, or (ii) that purports to meet the requirements of
  section 10(a)(3) of the Act and is used in connection with an offering of
  securities subject to Rule 415, will be filed as a part of an amendment to
  the registration statement and will not be used until such amendment is
  effective, and that, for purposes of determining any liability under the
  Securities Act of 1933, each such post-effective amendment shall be deemed
  to be a new registration statement relating to the securities offered
  therein, and the offering of such securities at that time shall be deemed
  to be the initial bona fide offering thereof.

     Insofar as indemnification for liabilities arising under the Securities
  Act of 1933 may be permitted to directors, officers and controlling persons
  of the registrant pursuant to the foregoing provisions, or otherwise, the
  registrant has been advised that in the opinion of the Securities and
  Exchange Commission such indemnification is against public policy as
  expressed in the Act and is, therefore, unenforceable. In

                                      II-7
<PAGE>

  the event that a claim for indemnification against such liabilities (other
  than the payment by the registrant of expenses incurred or paid by a
  director, officer or controlling person of the registrant in the successful
  defense of any action, suit or controlling person of the registrant in the
  successful defense of any action, suit or proceeding) is asserted by such
  director, officer or controlling person in connection with the securities
  being registered, the registrant will, unless in the opinion of its counsel
  the matter has been settled by controlling precedent, submit to a court of
  appropriate jurisdiction the question whether such indemnification by it is
  against public policy as expressed in the Act and will be governed by the
  final adjudication of such issue.

   (b) The undersigned registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the prospectus pursuant to
Items 4, 10(b), 11 or 13 of this form, within one business day of receipt of
such request, and to send the incorporated documents by first class mail or
other equally prompt means. This includes information contained in documents
filed subsequent to the effective date of this registration statement through
the date of responding to the request.

   (c) The undersigned registrant hereby undertakes to supply by means of a
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in this registration statement when it became effective.

                                          August 12, 1999

Adelphia Communications Corporation
Main at Water Street
Coudersport, PA 16915

Dear Sirs:

   We have acted as counsel to Adelphia Communications Corporation, a Delaware
corporation ("Adelphia," the "Company" or the "Registrant"), in connection with
its Registration Statement on Form S-4 (the "Registration Statement") filed
with the Securities and Exchange Commission relating to the proposed offering
of the Company's Class A common stock, par value $.01 per share (the "Shares"),
pursuant to the terms of the Agreement and Plan of Merger, dated as of March 5,
1999, as amended (the "Merger Agreement"), by and among Adelphia, Adelphia
Acquisition Subsidiary, Inc., a Delaware corporation and a wholly owned
subsidiary of Adelphia ("Merger Sub"), and Century Communications Corp.
("Century"), which provides for the merger of Century with and into Merger Sub,
with Merger Sub surviving the merger (the "Merger"). The Shares are to be
issued to the shareholders of Century, in accordance with the terms of the
Merger Agreement, in exchange for such shareholder's shares of Century Class A
common stock, par value $.01 per share and Century Class B common stock, par
value $.01 per share.

   In connection with the proposed offering, we have examined the Company's
Certificate of Incorporation and Bylaws, as presently in effect, the Company's
relevant corporate proceedings, the draft Registration Statement on Form S-4
covering the proposed offering, including the Proxy Statement/Prospectus filed
as a part of the Registration Statement, the Merger Agreement, and such other
documents, records, certificates or public officials, statutes and decisions as
we considered necessary to express the opinions contained herein. In the
examination of such documents, we have assumed the genuineness of all
signatures and the authenticity of all documents submitted to us as originals
and the conformity to the original documents of all documents submitted to us
as certified or photostatic copies.

   Based on the foregoing, we are of the opinion that:

  1.  The Shares have been duly authorized for issuance.

  2.  The Shares, when issued and delivered to the shareholders of Century in
      exchange for shares of Century Class A common stock and Century Class B
      common stock in accordance with the terms of the Merger Agreement, will
      be validly issued, fully paid and nonassessable.

   Our opinion is limited to the laws of the Commonwealth of Pennsylvania, the
General Corporation Law of the State of Delaware and the United States of
America, insofar as such laws apply, and we express no opinion as to conflicts
of law rules, or the laws of any states or jurisdictions, including federal
laws regulating securities or other federal laws, or the rules and regulations
of stock exchanges or any other regulatory body, other than as specified above.

   We assume no obligation to advise you of any changes to the foregoing
subsequent to the delivery of this opinion letter. This opinion letter has been
prepared solely for your use in connection with the filing of the Registration
Statement on the date of this opinion letter and shall not be quoted in whole
or in part or otherwise referred to, nor filed with or furnished to any
governmental agency or other person or other entity, without the prior written
consent of this firm.

   We hereby consent to the filing of this opinion letter as Exhibit 5.01 to
the Registration Statement and to any reference to us in the Prospectus which
is a part hereof. In giving such consent, we do not admit and we disclaim that
we come within the category of persons whose consent is required under Section
7 of the Securities Act of 1933, or the rules and regulations issued by the
Securities and Exchange Commission thereunder.

                                          Sincerely,

   Please read the instructions in this Form of Election and Letter of
Transmittal carefully before completing this Form of Election and Letter of
Transmittal. The election deadline is 5:00 p.m., New York City time, on
September 30, 1999 (the "Election Deadline"), by which date a completed Form
of Election and Letter of Transmittal, together with your stock certificates
or a Guarantee of Delivery, must be received by the Exchange Agent in order
for any Cash Election or Mixed Election (as such terms are defined below)
contained herein to be valid. Any stockholder wishing to make a Stock Election
(as defined below) need not submit the Form of Election and Letter of
Transmittal prior to the Election Deadline. Any Form of Election and Letter of
Transmittal received by the Exchange Agent after the Election Deadline,
whether or not a Stock Election is indicated thereon, shall be deemed to
indicate a Stock Election.

   The tax consequences to a holder of Century Class A Shares will vary
depending upon, among other things, whether a Stock Election, Cash Election or
Mixed Election is made. For a summary of the federal income tax consequences
of the receipt of the Merger Consideration (as defined below), see "The
Merger--Material Federal Income Tax Consequences" in the Joint Proxy
Statement/Prospectus dated August 12, 1999 (including all documents
incorporated therein, and as it may be amended from time to time, the "Joint
Proxy Statement/Prospectus") delivered prior hereto. You are urged, in
addition, to consult with your tax advisor.

   If your stock certificate(s) has (have) been lost, stolen or destroyed and
you require assistance in replacing it (them), see General Instruction 15
below. You cannot submit an effective Form of Election and Letter of
Transmittal without attaching your stock certificate(s) to this Form of
Election and Letter of Transmittal. If you submit a Guarantee of Delivery in
place of your stock certificate(s), your stock certificate(s) must be
delivered within three Nasdaq National Stock Market trading days thereafter.
Therefore, if you wish to make an effective election, it is critical that you
act immediately to obtain replacement stock certificates.

Ladies and Gentlemen:

   Pursuant to the Agreement and Plan of Merger, dated as of March 5, 1999, as
amended on July 12, 1999 and on July 29, 1999 (the "Agreement"), among
Adelphia, Century and Merger Sub, the undersigned hereby makes the election or
elections set forth herein and surrenders to the Exchange Agent for
cancellation, as exchange agent (the "Exchange Agent"), certificates
representing (or, if after the effective time of the Merger (the "Effective
Time"), formerly representing) all of the undersigned's Century Class A Shares
(each such certificate, a "Century Class A Share Certificate"), listed in Box
A above in exchange for either (i) the right to receive 0.77269147 of a share
of Adelphia Class A common stock for each share of Century Class A common
stock (such election, a "Stock Election"), (ii) the right to receive $44.14 in
cash, without interest (such election, a "Cash Election") or (iii) a
combination of cash for Century Class A Shares listed under the column heading
"Shares to Receive Cash Consideration" in Box A above and Adelphia Class A
common stock for Century Class A Shares listed under the column heading
"Shares to Receive Stock Consideration" in Box A above (such election, a
"Mixed Election"). Adelphia Class A common stock issued in connection with the
Merger is referred to herein as the "Stock Consideration" and cash paid in
connection with the Merger to record holders of Century Class A common stock
as of the Effective Time is referred to herein as the "Cash Consideration."
The Stock Consideration and the Cash Consideration are collectively referred
to as the "Merger Consideration."

   The undersigned understands that the election referred to above is subject
to certain terms, conditions and limitations that have been set forth in the
Agreement (including, but not limited to, the fact that the aggregate number
of Century Class A Shares that may be converted into the right to receive the
Cash Consideration shall not exceed 20.76% of the number of Century Class A
Shares outstanding immediately prior to the effective time of the Merger, and
consequently it is possible that certain Century stockholders making a Cash
Election or a Mixed Election may receive Adelphia Class A common stock in lieu
of the cash they would otherwise receive pursuant to such elections), the
General Instructions below and the Joint Proxy Statement/Prospectus. The
Agreement, as amended, is included as Appendix A to the Joint Proxy
Statement/Prospectus. Extra copies of this Form of Election and Letter of
Transmittal and the Joint Proxy Statement/Prospectus may be requested from
Beacon Hill Partners, Inc., the Information Agent, at the phone number shown
above, or from American Stock Transfer & Trust Company, the Exchange Agent, at
the addresses shown above. The delivery of this Form of Election and Letter of
Transmittal to the Exchange Agent is acknowledgment of the receipt of the
Joint Proxy Statement/Prospectus.

   The undersigned hereby represents and warrants that the undersigned is as
of the date hereof, and will be as of the Effective Time, the registered
holder of the Century Class A Shares represented by the Century Class A
Certificate(s) surrendered herewith, with good title to the above-described
Century Class A Shares and full power and authority to sell, assign and
transfer such Century Class A Shares, free and clear of all liens, claims and
encumbrances, and not subject to any adverse claims. The undersigned will,
upon request, execute any additional documents necessary or desirable to
complete the surrender and exchange of such Century Class A Shares. The
undersigned hereby irrevocably appoints the Exchange Agent, as agent of the
undersigned to effect the exchange pursuant to the Agreement and the General
Instructions hereto. All authority conferred or agreed to be conferred in this
Form of Election and Letter of Transmittal shall be binding upon the
successors, assigns, heirs, executors, administrators and legal
representatives of the undersigned and shall not be affected by, and shall
survive, the death or incapacity of the undersigned.

                                   ELECTION

   The appropriate box must be checked in Box A above in order to make a Cash
Election or a Mixed Election (each as defined above). The box indicating a
Stock Election (as defined above) may be checked by those wishing to make a
Stock Election but any Form of Election and Letter of Transmittal received by
the Exchange Agent without any checked election box will be treated as
indicating a Stock Election.

                                       3

   Your choice of Election for each share of Century Class A common stock is
as follows:

      Cash Election   $44.14 in cash, without interest

      Stock Election  0.77269147 Adelphia Class A Shares
</TABLE>

   All elections are subject to the proration procedures set forth in the
Merger Agreement, a copy of which is attached to the Joint Proxy
Statement/Prospectus as Appendix A. The proration procedures are also
described in the Joint Proxy Statement/Prospectus under the captions "The
Merger--Cash and Stock Elections;--Proration," " The Merger Agreement and
Related Agreements--The Merger Agreement--Election; Conversion of Century
Shares; Proration" and "--Proration" and in General Instruction 4 below. You
are urged to read the Joint Proxy Statement/Prospectus in its entirety before
completing this Form of Election and Letter of Transmittal.

   All holders of Century Class A Shares wishing to make a Cash Election or a
Mixed Election must deliver to the Exchange Agent a properly completed Form of
Election and Letter of Transmittal prior to 5:00 p.m., New York City time, on
September 30, 1999. All holders submitting a Form of Election and Letter of
Transmittal after such time will be deemed to have made a Stock Election
regardless of the election specified on such form. Holders of Century Class A
Shares wishing to make a Stock Election are not required to submit this Form
of Election and Letter of Transmittal prior to the Election Deadline or prior
to the Effective Time; however, in order to receive the Merger Consideration
for their Century ClassA Shares, they must submit this Form of Election and
Letter of Transmittal along with their Century Class A Share Certificate(s).

   The Exchange Agent reserves the right to deem that you have checked the
"Stock Election" Box if:

   A. No Election choice is indicated in Box A above;

   B. More than one Election choice is indicated in Box A above;

   C. You fail to follow the General Instructions on this Form of Election and
Letter of Transmittal (including submission of your certificates) or otherwise
fail to properly make an election;

   D. A completed Form of Election and Letter of Transmittal (including
submission of your certificates) is not actually received by the Election
Deadline; or

   E. You return this Form of Election and Letter of Transmittal using the
Guaranteed Delivery procedures and do not deliver your certificate(s)
representing the shares in respect of which an Election is being made within
three (3) Nasdaq National Stock Market trading days thereafter.

   Notwithstanding anything to the contrary in this Form of Election and
Letter of Transmittal, the Exchange Agent reserves the right to waive any
flaws in a completed Form of Election and Letter of Transmittal but shall be
under no obligation to do so.

   In order to receive the Merger Consideration, this Form of Election and
Letter of Transmittal must be (i) completed and signed in the space provided
below and on the Substitute Form W-9, and (ii) mailed or delivered with your
certificate(s) to the Exchange Agent at the address set forth above. In order
to properly make a Cash Election or Mixed Election, these actions must be
taken in a timely fashion such that the Form of Election and Letter of
Transmittal is received by the Exchange Agent prior to the Election Deadline.
In order to properly make a Stock Election (or obtain the benefits of a deemed
Stock Election), these actions must be taken at some time prior to or after
the Effective Time.

                                       4
<PAGE>

   The method of delivery of the certificates and all other required documents
is at the election and risk of the holder of Century Class A Shares; however,
if the certificates are sent by mail, it is recommended that they be sent by
registered mail, appropriately insured, with return receipt requested.

   Unless otherwise indicated below under "Special Issuance and Payment
Instructions," in exchange for the enclosed certificates, the undersigned
requests delivery of the Merger Consideration in the name of the undersigned.
Similarly, unless otherwise indicated below under "Special Delivery
Instructions," the undersigned requests that the Merger Consideration be
mailed to the undersigned at the address shown above. In the event that both
the "Special Delivery Instructions" and the "Special Issuance and Payment
Instructions" are completed, please issue the Merger Consideration in the name
of, and mail the Merger Consideration to, the person or entity so indicated at
the address so indicated. Appropriate signature guarantees have been included
with respect to Century Class A Shares for which Special Issuance and Payment
Instructions have been given.

   Consummation of the Merger is still subject to approval of the stockholders
of Century and Adelphia and to the satisfaction of certain other conditions.

   In the event that the Agreement is terminated, the Exchange Agent will
promptly return certificates previously submitted with any Form of Election
and Letter of Transmittal. In such event, Century Class A Shares held through
The Depository Trust Company are expected to be available for sale or transfer
promptly following such termination; however, certificates representing
Century Class A Shares held of record directly by the beneficial owners of
such Century Class A Shares will be returned as promptly as practicable by
first class, insured mail.

exchange for his or her certificate(s). No interest will accrue on the Cash
Consideration. If your stock certificate(s) is (are) lost, stolen or
destroyed, please refer to General Instruction 15 below.

   A holder of Century shares must check the appropriate Election Box in Box A
above to make an effective Cash Election or Mixed Election.

   Your election is subject to certain terms, conditions and limitations that
have been set out in the Agreement and the Joint Proxy Statement/Prospectus.
The Agreement is included as Appendix A to the Joint Proxy
Statement/Prospectus. Extra copies of the Joint Proxy Statement/Prospectus may
be requested from Beacon Hill Partners, Inc., the Information Agent, at the
phone number shown above, or from American Stock Transfer & Trust Company, the
Exchange Agent, at the address shown above. The delivery of this Form of
Election and Letter of Transmittal to the Exchange Agent is acknowledgment of
receipt of the Joint Proxy Statement/Prospectus.

   1. Election Deadline. For any Cash Election or Mixed Election contained
herein to be considered, this Form of Election and Letter of Transmittal,
properly completed, and your Century Class A stock certificate(s) must be
received by the Exchange Agent at the address shown above on this Form of
Election and Letter of Transmittal no later than 5:00 p.m., New York City
Time, on September 30, 1999. The Exchange Agent will determine whether any
Form of Election and Letter of Transmittal is received on a timely basis and
whether a Form of Election and Letter of Transmittal has been properly
completed. Any such determinations shall be conclusive and binding.

   The Election Deadline is 5:00 p.m., New York City time, on September 30,
1999.

   2. Effect of Asserting Dissenters' Rights. A Form of Election will not be
valid and will be ignored if completed by a holder of Century Class A Shares
that provides Century (and Century actually receives) written notice of intent
to assert dissenters' rights and does not vote in favor of the Merger and
takes such other actions as may be required prior to the Effective Time to
perfect dissenters' rights under applicable law. Any such holder that
subsequently fails to perfect dissenters' rights will receive $9.16426528 in
cash and 0.61222732 of a share of Adelphia Class A common stock, without
interest in exchange for each share of Century Class A common stock.

   3. Revocation or Change of Form of Election and Letter of Transmittal. Any
Form of Election and Letter of Transmittal may be revoked or changed by
written notice to the Exchange Agent from the person submitting such Form of
Election and Letter of Transmittal, but to be effective such notice must be
received by the Exchange Agent at or prior to the Election Deadline. The
Exchange Agent will have reasonable discretion to determine whether any
revocation or change is received on a timely basis and whether any such
revocation or change has been properly made. Any such determinations shall be
conclusive and binding.

   4. Election Procedures/Proration. To properly complete Box A, (1) the
undersigned must check either the Cash Election, Mixed Election or Stock
Election (if no box is checked, the Stock Election box will be deemed to have
been checked); (2) the name and address of the registered holder(s) must be
set forth in the column under the heading "Name and Address of Registered
Holder(s);" (3) the number of each Century Class A Share

                                       8
<PAGE>

Certificate surrendered herewith must be written in the column under the
heading "Certificate Number" along with the total number of Century Class A
Shares represented by such certificate(s) under the heading "Total Number of
Shares," and (4) in the event of a Mixed Election, the number of Century Class
A Shares to receive cash under the heading "Shares to Receive Cash
Consideration" and the number of Century Class A Shares to receive Adelphia
Class A common stock under the heading "Shares to Receive Stock
Consideration." As set forth in the Joint Proxy Statement/Prospectus, no more
than 20.76% of the outstanding Century Class A Shares (other than shares held
by dissenting stockholders and Century-held Shares) will be exchanged for cash
and no more than 79.24% of such outstanding Century Class A Shares will be
exchanged for Adelphia Class A common stock. If the Elections result in an
oversubscription of either the Cash Consideration or the Stock Consideration,
the procedures for allocating the Merger Consideration set forth in the
Agreement and described in the Joint Proxy Statement/Prospectus will be
followed by the Exchange Agent. Accordingly, there can be no assurance that a
Cash Election, Mixed Election or Stock Election made by you will result in
your receipt of the desired type and amount of Merger Consideration. See the
Joint Proxy Statement/Prospectus under the caption "The Merger Agreement and
Related Agreements--The Merger Agreement--Election; Conversion of Century
Shares; Proration" and "--Proration." The effectiveness of Elections that are
accompanied by Guarantees of Delivery may not be finally determined until
three Nasdaq National Market trading days after the Election Deadline. The
Merger Consideration is expected to be mailed promptly after the determination
of any proration in the Merger.

   5. Termination of Merger Agreement. Consummation of the Merger is subject
to the required approval of the stockholders of Century and Adelphia and to
the satisfaction of certain other conditions. No payments related to any
surrender of Century Class A Share Certificates will be made prior to the
consummation of the Merger, and no payments will be made if the Merger
Agreement is terminated. If the Merger Agreement is terminated, all Century
Class A Elections will be void and of no effect and the Exchange Agent will
promptly return all Century Class A Share Certificates previously received by
it. In such event, Century Class A Shares held through The Depository Trust
Company are expected to be available for sale or transfer promptly following
such termination. Certificates representing Century Class A Shares held of
record directly by the beneficial owners of such Century Class A Shares will
be returned by the Exchange Agent without charge to the holder as promptly as
practicable by first class, insured mail.

   6. No Fractional Interests. No certificate representing fractional shares
of Adelphia Class A common stock will be issued to holders of Century Class A
Shares. Upon surrender of certificates representing Century Class A Shares
after the Merger, holders of Century Class A Shares will be paid cash instead
of any fractional shares of Adelphia Class A common stock they would otherwise
receive. All fractional shares of Adelphia Class A common stock that a holder
of shares of Century Class A Shares otherwise would be entitled to receive as
a result of the merger will be aggregated. If a fractional share results from
such aggregation, the amount of cash to be received instead of the fractional
share will be equal to:

  .  the fraction of a share that would otherwise be received multiplied by

  .  the closing price of a share of Adelphia Class A common stock on the
     Nasdaq National Market on the trading day immediately preceding the
     effective date of the Merger.

   7. Guarantee of Signatures. Signatures on this Form of Election and Letter
of Transmittal need not be guaranteed unless the "Special Issuance and Payment
Instructions" section has been completed and payment is to be made to someone
other than the registered holder(s) of Century Class A Shares with respect to
the surrendered certificates. In such event, signatures on this Form of
Election and Letter of Transmittal must be guaranteed by a financial
institution (including most commercial banks, savings and loan associations
and brokerage houses) that is a participant in the Security Transfer Agent's
Medallion Program, the New York Share Exchange Medallion Program or the Share
Exchange Medallion Program. Public notaries cannot execute acceptable
guarantees of signatures.

   8. Delivery of Form of Election and Letter of Transmittal and Century Class
A Share Certificates; Guarantee of Delivery. This Form of Election and Letter
of Transmittal, properly completed and duly

                                       9
<PAGE>

executed, together with your Century Class A Share Certificate(s) or a
Guarantee of Delivery, should be delivered to the Exchange Agent at the
address set forth above. All Century Class A Share Certificates held by a
single stockholder and not by a nominee, trustee or other representative (as
set forth in General Instruction 9) must all be on a single Letter of
Transmittal. A Guarantee of Delivery of such Century Class A Share
Certificate(s) must be made by a firm which is a member of a registered
national securities exchange or of the National Association of Securities
Dealers, Inc. or a commercial bank or trust company having an office or
correspondent in the United States, and any Century Class A Share
Certificate(s) covered by a Guarantee of Delivery must in fact be delivered to
the Exchange Agent within three Nasdaq National Market trading days after the
date of execution of such Guarantee of Delivery. Failure to deliver such
Century Class A Share Certificate(s) shall invalidate any Election, and a
Stock Election shall be deemed to have been made by the Century Class A Shares
covered thereby. The method of delivery of the Form of Election and Letter of
Transmittal, the Century Class A Share Certificates and all other required
documents is at the election and risk of the holder of Century Class A Shares.
If you choose to send the materials by mail, it is recommended that they be
sent by registered mail, appropriately insured, with return receipt requested.
Delivery of the materials will be deemed effective, and risk of loss with
respect thereto will pass, only when such materials are actually received by
the Exchange Agent. By delivering certificates for Century Class A Shares, the
registered holder of such certificates releases Century, Merger Sub and their
respective affiliates, directors, officers, employees, partners, agents,
advisors and representatives, and their respective successors and assigns,
from any and all claims arising from or in connection with the purchase or
ownership of such Century Class A Shares or the sale thereof or receipt of
shares of common stock of the surviving corporation pursuant to the Agreement.

   9. Shares Held By Nominees, Trustees or Other Representatives; Multiple
Elections. Holders of record of Century Class A Shares who hold such shares as
nominees, trustees or in other representative or fiduciary capacities (a
"Representative") may submit one or more Forms of Election and Letters of
Transmittal covering the aggregate number of Century Class A Shares held by
such Representative for the beneficial owners for whom the Representative is
making an affirmative Cash Election, Mixed Election or Stock Election or a
deemed Stock Election, provided that such Representative certifies that each
Form of Election and Letter of Transmittal covers all of the Century Class A
Shares held by such Representative for any single beneficial owner. Any
Representative that makes an affirmative Cash Election, Mixed Election or
Stock Election or a deemed Stock Election may be required to provide the
Exchange Agent with such documents and/or additional certifications, if
requested, in order to satisfy the Exchange Agent that such Representative
holds such Century Class A Shares for a particular beneficial owner. If any
Century Class A Shares are not covered by an effective Form of Election and
Letter of Transmittal, they will be deemed to be covered by a deemed Stock
Election.

   10. Inadequate Space. If the space provided herein is inadequate, the share
certificate numbers and the numbers of Century Class A Shares represented
thereby should be listed on additional sheets and attached hereto.

   11. Signatures on Form of Election and Letter of Transmittal, Stock Powers
and Endorsements.

   (a) All signatures must correspond exactly with the name written on the
face of the certificate(s) without alteration, variation or any change
whatsoever.

   (b) If the certificate(s) surrendered is (are) held of record by two or
more joint owners, all such owners must sign this Form of Election and Letter
of Transmittal.

   (c) If any surrendered Century Class A Shares are registered in different
names on several certificates, it will be necessary to complete, sign and
submit as many separate Forms of Election and Letters of Transmittal as there
are different registrations of certificates.

   (d) If this Form of Election and Letter of Transmittal is signed by a
person(s) other than the record holder(s) of the certificates listed (other
than as set forth in paragraph (e) below), such certificates must be endorsed
or accompanied by appropriate stock powers, in either case signed exactly as
the name(s) of the record holder(s) appears on such certificate(s).


                                      10
<PAGE>

   (e) If this Form of Election and Letter of Transmittal is signed by a
trustee, executor, administrator, guardian, attorney-in-fact, officer of a
corporation or other person acting in a fiduciary or representative capacity
and such person is not the record holder of the accompanying certificates, he
or she must indicate the capacity when signing and must submit proper evidence
of his or her authority to act.

   12. Stock Transfer Taxes. In the event that any transfer or other taxes
become payable by reason of the issuance of the Merger Consideration in any
name other than that of the holder of Century Class A Shares, such transferee
or assignee must pay such tax to the Exchange Agent or must establish to the
satisfaction of the Exchange Agent that such tax has been paid.

   13. Special Issuance And Delivery Instructions. In the "Special Issuance
and Payment Instructions" box, indicate the name and/or address of the
person(s) to whom the Merger Consideration is to be issued and mailed only if
the Merger Consideration (whether cash or Adelphia Class A common stock) is to
be issued in the name of someone other than the person(s) signing this Form of
Election and Letter of Transmittal. If the "Special Issuance and Payment
Instructions" box is completed, the Exchange Agent will issue the Merger
Consideration in the name of, and will mail the Merger Consideration to, the
person or entity so indicated at the address so indicated, but only after the
Exchange Agent has been provided with satisfactory evidence of the payment of,
or exemption from payment of, any applicable stock transfer taxes payable on
account of the transfer to such person or entity prior to the delivery of the
Merger Consideration.

   In the "Special Delivery Instructions" box, indicate the address to which
the Merger Consideration is to be mailed in the name of the undersigned only
if different from the address set forth in Box A.

   14. Withholding. Each surrendering holder of Century Class A Shares is
required to provide the Exchange Agent with such holder's correct Taxpayer
Identification Number ("TIN") on the Substitute Form W-9 and to certify
whether such holder is subject to backup withholding. The TIN that must be
provided is that of the holder of Century Class A common stock with respect to
the certificate(s) surrendered herewith or of the last transferee appearing on
the transfers attached to or endorsed on such certificate(s) (or, if a check
is made payable to another person as provided in the box above entitled
"Special Issuance and Payment Instructions," then the TIN of such person).
Failure to provide the information on the Substitute Form W-9 may subject the
surrendering holder of Century Class A common stock to 31% federal income tax
withholding on payments made to such surrendering holder with respect to the
Century Class A Shares and on future dividends, if any, paid by Adelphia. A
holder of Century Class A common stock must cross out item (2) in the
certification box of Substitute Form W-9 if such holder has been notified by
the Internal Revenue Service ("IRS") that such holder is currently subject to
backup withholding. The box in Part 3 of the Substitute Form W-9 should be
checked if the surrendering holder of Century Class A common stock has not
been issued a TIN and has applied for a TIN or intends to apply for a TIN in
the near future. If the box in Part 3 is checked and the Exchange Agent is not
provided with a TIN, Adelphia will withhold 31% of all such payments and
dividends but will return such amounts to the holder of Century Class A common
stock if a TIN is later provided to the Exchange Agent within 60 days. Foreign
investors should consult their tax advisors regarding the need to complete IRS
Form W-8 and any other forms that may be required.

   15. Lost, Stolen or Destroyed Certificates. You cannot submit an effective
Form of Election and Letter of Transmittal without attaching your
certificate(s) to this Form of Election and Letter of Transmittal. If your
certificate(s) has (have) been lost, stolen or destroyed, you are urged to
call the Information Agent toll-free at (800) 755-5001 immediately to receive
instructions as to the steps you must take in order to effect an exchange of
your Century Class A Shares.

   16. Elections, Certificates and Share Allocations. Each holder of Century
Class A Shares is entitled to make a Cash Election, a Stock Election or a
Mixed Election, provided the Form of Election and Letter of Transmittal for
any holder making a Cash Election or a Mixed Election is properly completed
and received by the Exchange Agent prior to the Election Deadline of 5:00
p.m., New York City time, on September 30, 1999. All holders of Century Class
A common stock must complete Box A in order to effect a Cash Election or Mixed

                                      11
<PAGE>

Election. To properly complete Box A, the number of each certificate
surrendered herewith must be written in the column under the heading
"Certificate Number." In the event such holder is making a Cash Election as to
all shares, the box immediately to the left of the words "Cash Election" must
be checked, the number of Century Class A Shares represented by each
certificate surrendered herewith should be written into the column under the
heading "Shares to Receive Cash Consideration" beside each certificate number,
and the column under the heading "Shares to Receive Stock Consideration"
should be left blank. In the event such holder is making a Stock Election as
to all shares, the box immediately to the left of the words "Stock Election"
may be checked (although all Forms of Election and Letters of Transmittal that
are improperly completed or that do not specify an election will be deemed to
have specified a Stock Election as to all shares), the number of Century Class
A Shares represented by each certificate surrendered herewith should be
written into the column under the heading "Shares to Receive Stock
Consideration" beside each certificate number, and the column under the
heading "Shares to Receive Cash Consideration" should be left blank. In the
event such holder is making a Mixed Election, the box immediately to the left
of the words "Mixed Election" should be checked and such holder should
allocate his or her shares represented by such holder's certificates between
the columns marked "Shares to Receive Stock Consideration" and "Shares to
Receive Cash Consideration" according to such holder's preferences. Holders of
Century Class A Shares should see "Important Tax Information" below for
important tax consequences of various elections.

   17. Miscellaneous. Adelphia and the Exchange Agent are not under any duty
to give notification of defects in any Form of Election and Letter of
Transmittal. Adelphia and the Exchange Agent shall not incur any liability for
failure to give such notification, and each of Adelphia and the Exchange Agent
has the absolute right to reject any and all Forms of Election and Letters of
Transmittal not in proper form or to waive any irregularities or flaws in any
Form of Election and Letter of Transmittal.

   18. Information and Additional Copies. Information and additional copies of
this Form of Election and Letter of Transmittal may be obtained from the
Information Agent by telephoning toll-free at (800) 755-5001 or from the
Exchange Agent by telephoning toll-free at (800) 937-5449.

                           IMPORTANT TAX INFORMATION

   Withholding. Under the federal income tax law, the Exchange Agent is
required to file a report with the IRS disclosing any payments of cash being
made to each holder of certificates pursuant to the Agreement and to impose
31% backup withholding if required. If the correct certifications on
Substitute Form W-9 are not provided, a $50 penalty may be imposed by the IRS
and payments made for Century Class A Shares may be subject to backup
withholding of 31%. Backup withholding is also required if the IRS notifies
the recipient that they are subject to backup withholding as a result of a
failure to report all interest and dividends.

   In order to avoid backup withholding resulting from a failure to provide a
correct certification, a holder of Century Class A Shares must, unless an
exemption applies, provide the Exchange Agent with his correct TIN on
Substitute Form W-9 as set forth on this Form of Election and Letter of
Transmittal. Such person must certify under penalties of perjury that such
number is correct and that such holder is not otherwise subject to backup
withholding. The TIN that must be provided is that of the registered holder of
the Century Class A Share Certificate(s) or of the last transferee appearing
on the transfers attached to or endorsed on the Century Class A Share
Certificate(s) (or, if a check is made payable to another person as provided
in the box entitled "Special Issuance and Payment Instructions," then the TIN
of such person). Foreign investors should consult their tax advisors regarding
the need to complete IRS Form W-8 and any other forms that may be required.

   Backup withholding is not an additional federal income tax. Rather, the
federal income tax liability of a person subject to backup withholding will be
reduced by the amount of tax withheld. If backup withholding results in an
overpayment of taxes, a refund may be obtained from the IRS.

   Please read the enclosed Guidelines for Certification of Taxpayer
Identification Number on Substitute Form W-9 for additional important
information on how to complete the Substitute Form W-9.

   For a summary of the federal income tax consequences of the receipt of the
Merger Consideration, see "The Merger--Material Federal Income Tax
Consequences" in the Joint Proxy Statement/Prospectus.

                         [Letterhead of Century Comm.]
August 12, 1999

Dear Century Stockholder:

   It is currently anticipated that the merger (the "Merger") of Century
Communications Corp. ("Century") with and into Adelphia Acquisition Subsidiary,
Inc. ("Merger Sub"), a wholly owned subsidiary of Adelphia Communications
Corporation ("Adelphia"), will, subject to stockholder approval and other
closing conditions, be consummated subsequent to the special meetings.

   In accordance with the terms of the agreement and plan of merger, as amended
(the "Merger Agreement"), you may surrender the stock certificate(s)
representing all of your Century Class A Shares in exchange for certificates
representing shares of Class A common stock of Adelphia at an exchange ratio of
0.77269147 of a share of Adelphia Class A common stock for each Century Class A
Share, subject to the proration procedure as described below. The Merger
Agreement also allows you to elect to receive on a share by share basis, in
lieu of Adelphia Class A common stock, $44.14 in cash for all or a portion of
your Century Class A Shares, subject to the proration procedure as described
below, or a combination of cash and Adelphia Class A common stock. Pursuant to
the terms of the Merger Agreement, the aggregate number of Century Class A
Shares that may be converted into the right to receive cash will not exceed
20.76% of the number of Century Class A Shares outstanding immediately prior to
the Effective Time of the Merger (excluding dissenting stockholders) and the
aggregate number of Century Class A Shares that may be converted into the right
to receive shares of Adelphia Class A common stock will not exceed 79.24% of
the number of Century Class A Shares outstanding immediately prior to the
Effective Time (excluding dissenting stockholders). Stockholders of Century who
elect to receive cash should be aware that they may receive some shares of
Adelphia Class A common stock instead of cash in the Merger and stockholders of
Century who elect to receive stock should be aware that they may receive some
cash instead of Adelphia Class A common stock in the Merger.

   As of the effective date of the Merger, your certificate(s) for Century
Class A Shares automatically will be deemed to evidence ownership of the number
of shares of Adelphia Class A common stock into which such Century Class A
Shares have been converted, if you did not elect cash. However, no such
dividends or other distributions (if any) made with respect to your Adelphia
Class A common stock will be distributed until your certificate(s) for Century
Class A Shares have been surrendered for exchange and a properly completed
green Form of Election and Letter of Transmittal has been submitted. Therefore,
we encourage you to exchange your certificate(s) as soon as possible.

   A green Form of Election and Letter of Transmittal and related instructions,
together with a return envelope are enclosed for your use in delivering or
mailing your certificates to American Stock Transfer & Trust Company, the
Exchange Agent for this transaction. The green Form of Election and Letter of
Transmittal must be properly executed and returned with your certificates. If
you elect all or a portion of the consideration for your shares in cash, your
Form of Election and Letter of Transmittal and certificates must be received by
5:00 p.m., New York City time, on September 30, 1999. Please read the Form of
Election and Letter of Transmittal carefully, along with the General
Instructions.

   We urge you to act promptly in this matter. If you have any questions,
please contact American Stock Transfer & Trust Company, the Exchange Agent,
toll-free at (800) 937-5449 or Beacon Hill Partners, the Information Agent,
toll-free at (800) 755-5001.

                                              /s/ Leonard Tow

Transmittal carefully before completing this Form of Election and Letter of
Transmittal. The election deadline is 5:00 p.m., New York City time, on
September 30, 1999 (the "Election Deadline"), by which date a completed Form
of Election and Letter of Transmittal, together with your stock certificates

for any Cash Election or Mixed Election (as such terms are defined below)
contained herein to be valid. Any stockholder wishing to make a Stock Election

Transmittal received by the Exchange Agent after the Election Deadline,
whether or not a Stock Election is indicated thereon, shall be deemed to
indicate a Stock Election.

   The tax consequences to a holder of Century Class B Shares will vary
depending upon, among other things, whether a Stock Election, Cash Election or
Mixed Election is made. For a summary of the federal income tax consequences
of the receipt of the Merger Consideration (as defined below), see "The
Merger--Material Federal Income Tax Consequences" in the Joint Proxy
Statement/Prospectus dated August 12, 1999 (including all documents
incorporated therein, and as it may be amended from time to time, the "Joint
Proxy Statement/Prospectus") delivered prior hereto. You are urged, in

you require assistance in replacing it (them), see General Instruction 15

Transmittal without attaching your stock certificate(s) to this Form of
Election and Letter of Transmittal. If you submit a Guarantee of Delivery in
place of your stock certificate(s), your stock certificate(s) must be
delivered within three Nasdaq National Stock Market trading days thereafter.
Therefore, if you wish to make an effective election, it is critical that you
act immediately to obtain replacement stock certificates.

Ladies and Gentlemen:

   Pursuant to the Agreement and Plan of Merger, dated as of March 5, 1999, as
amended on July 12, 1999 and on July 29, 1999 (the "Agreement"), among
Adelphia, Century and Merger Sub, the undersigned hereby makes the election or
elections set forth herein and surrenders to the Exchange Agent for
cancellation, as exchange agent (the "Exchange Agent"), certificates
representing (or, if after the effective time of the Merger (the "Effective
Time"), formerly representing) all of the undersigned's Century Class B Shares
(each such certificate, a "Century Class B Share Certificate"), listed in Box
A above in exchange for either (i) the right to receive 0.84271335 of a share
of Adelphia Class A common stock for each share of Century Class B common
stock (such election, a "Stock Election"), (ii) the right to receive $48.14 in
cash, without interest (such election, a "Cash Election") or (iii) a
combination of cash for Century Class B Shares listed under the column heading
"Shares to Receive Cash Consideration" in Box A above and Adelphia Class A
common stock for Century Class B Shares listed under the column heading
"Shares to Receive Stock Consideration" in Box A above (such election, a
"Mixed Election"). Adelphia Class A common stock issued in connection with the
Merger is referred to herein as the "Stock Consideration" and cash paid in
connection with the Merger to record holders of Century Class B common stock
as of the Effective Time is referred to herein as the "Cash Consideration."
The Stock Consideration and the Cash Consideration are collectively referred
to as the "Merger Consideration."

   The undersigned understands that the election referred to above is subject
to certain terms, conditions and limitations that have been set forth in the
Agreement (including, but not limited to, the fact that the aggregate number
of Century Class B Shares that may be converted into the right to receive the
Cash Consideration shall not exceed 24.54% of the number of Century Class B
Shares outstanding immediately prior to the effective time of the Merger, and
consequently it is possible that certain Century stockholders making a Cash
Election or a Mixed Election may receive Adelphia Class A common stock in lieu
of the cash they would otherwise receive pursuant to such elections), the
General Instructions below and the Joint Proxy Statement/Prospectus. The
Agreement, as amended, is included as Appendix A to the Joint Proxy
Statement/Prospectus. Extra copies of this Form of Election and Letter of
Transmittal and the Joint Proxy Statement/Prospectus may be requested from
Beacon Hill Partners, Inc., the Information Agent, at the phone number shown
above, or from American Stock Transfer & Trust Company, the Exchange Agent, at
the addresses shown above. The delivery of this Form of Election and Letter of
Transmittal to the Exchange Agent is acknowledgment of the receipt of the
Joint Proxy Statement/Prospectus.

   The undersigned hereby represents and warrants that the undersigned is as
of the date hereof, and will be as of the Effective Time, the registered
holder of the Century Class B Shares represented by the Century Class B
Certificate(s) surrendered herewith, with good title to the above-described
Century Class B Shares and full power and authority to sell, assign and
transfer such Century Class B Shares, free and clear of all liens, claims and
encumbrances, and not subject to any adverse claims. The undersigned will,
upon request, execute any additional documents necessary or desirable to
complete the surrender and exchange of such Century Class B Shares. The
undersigned hereby irrevocably appoints the Exchange Agent, as agent of the
undersigned to effect the exchange pursuant to the Agreement and the General
Instructions hereto. All authority conferred or agreed to be conferred in this
Form of Election and Letter of Transmittal shall be binding upon the
successors, assigns, heirs, executors, administrators and legal
representatives of the undersigned and shall not be affected by, and shall
survive, the death or incapacity of the undersigned.

                                   ELECTION

   The appropriate box must be checked in Box A above in order to make a Cash
Election or a Mixed Election (each as defined above). The box indicating a
Stock Election (as defined above) may be checked by those wishing to make a
Stock Election but any Form of Election and Letter of Transmittal received by
the Exchange Agent without any checked election box will be treated as
indicating a Stock Election.

   Your choice of Election for each share of Century Class B common stock is

      Cash Election   $48.14 in cash, without interest

</TABLE>

   All elections are subject to the proration procedures set forth in the
Merger Agreement, a copy of which is attached to the Joint Proxy
Statement/Prospectus as Appendix A. The proration procedures are also
described in the Joint Proxy Statement/Prospectus under the captions "The
Merger--Cash and Stock Elections;--Proration," " The Merger Agreement and
Related Agreements--The Merger Agreement--Election; Conversion of Century
Shares; Proration" and "--Proration" and in General Instruction 4 below. You
are urged to read the Joint Proxy Statement/Prospectus in its entirety before
completing this Form of Election and Letter of Transmittal.

   All holders of Century Class B Shares wishing to make a Cash Election or a
Mixed Election must deliver to the Exchange Agent a properly completed Form of
Election and Letter of Transmittal prior to 5:00 p.m., New York City time, on
September 30, 1999. All holders submitting a Form of Election and Letter of
Transmittal after such time will be deemed to have made a Stock Election
regardless of the election specified on such form. Holders of Century Class B
Shares wishing to make a Stock Election are not required to submit this Form
of Election and Letter of Transmittal prior to the Election Deadline or prior
to the Effective Time; however, in order to receive the Merger Consideration
for their Century Class B Shares, they must submit this Form of Election and
Letter of Transmittal along with their Century Class B Share Certificate(s).

   The Exchange Agent reserves the right to deem that you have checked the
"Stock Election" Box if:

   A. No Election choice is indicated in Box A above;

   B. More than one Election choice is indicated in Box A above;

   C. You fail to follow the General Instructions on this Form of Election and
Letter of Transmittal (including submission of your certificates) or otherwise
fail to properly make an election;

   D. A completed Form of Election and Letter of Transmittal (including
submission of your certificates) is not actually received by the Election
Deadline; or

   E. You return this Form of Election and Letter of Transmittal using the
Guaranteed Delivery procedures and do not deliver your certificates
representing the shares in respect of which an Election is being made within
three (3) Nasdaq National Stock Market trading days thereafter.

   Notwithstanding anything to the contrary in this Form of Election and
Letter of Transmittal, the Exchange Agent reserves the right to waive any
flaws in a completed Form of Election and Letter of Transmittal but shall be
under no obligation to do so.

   In order to receive the Merger Consideration, this Form of Election and
Letter of Transmittal must be (i) completed and signed in the space provided
below and on the Substitute Form W-9, and (ii) mailed or delivered with your
certificate(s) to the Exchange Agent at the address set forth above. In order
to properly make a Cash Election or Mixed Election, these actions must be
taken in a timely fashion such that the Form of Election and Letter of
Transmittal is received by the Exchange Agent prior to the Election Deadline.
In order to properly make a Stock Election (or obtain the benefits of a deemed
Stock Election), these actions must be taken at some time prior to or after
the Effective Time.

                                       4
<PAGE>

   The method of delivery of the certificates and all other required documents
is at the election and risk of the holder of Century Class B Shares; however,
if the certificates are sent by mail, it is recommended that they be sent by
registered mail, appropriately insured, with return receipt requested.

   Unless otherwise indicated below under "Special Issuance and Payment
Instructions," in exchange for the enclosed certificates, the undersigned
requests delivery of the Merger Consideration in the name of the undersigned.
Similarly, unless otherwise indicated below under "Special Delivery
Instructions," the undersigned requests that the Merger Consideration be
mailed to the undersigned at the address shown above. In the event that both
the "Special Delivery Instructions" and the "Special Issuance and Payment
Instructions" are completed, please issue the Merger Consideration in the name
of, and mail the Merger Consideration to, the person or entity so indicated at
the address so indicated. Appropriate signature guarantees have been included
with respect to Century Class B Shares for which Special Issuance and Payment
Instructions have been given.

   Consummation of the Merger is still subject to approval of the stockholders
of Century and Adelphia and to the satisfaction of certain other conditions.

   In the event that the Agreement is terminated, the Exchange Agent will
promptly return certificates previously submitted with any Form of Election
and Letter of Transmittal. In such event, Century Class B Shares held through
The Depository Trust Company are expected to be available for sale or transfer
promptly following such termination; however, certificates representing
Century Class B Shares held of record directly by the beneficial owners of
such Century Class B Shares will be returned as promptly as practicable by
first class, insured mail.

                             GENERAL INSTRUCTIONS

   This Form of Election and Letter of Transmittal is to be completed and
submitted to the Exchange Agent prior to 5:00 p.m., New York City time, on
September 30, 1999, the Election Deadline, by those holders of Century Class B
Shares desiring to make a Cash Election or a Mixed Election. It must also be
used as a letter of transmittal at any time by any other holders of Century
Class B Shares who wish to receive the Stock Consideration. Until a record
holder's Century Share certificates are received by the Exchange Agent at the
address set forth above, together with such documents as the Exchange Agent
may require, and until the same are processed for exchange by the Exchange
Agent, such holder will not receive any certificates representing shares of
the Stock Consideration or the check representing the Cash Consideration in
exchange for his or her certificate(s). No interest will accrue on the Cash
Consideration. If your stock certificate(s) is (are) lost, stolen or
destroyed, please refer to General Instruction 15 below.

   A holder of Century shares must check the appropriate Election Box in Box A
above to make an effective Cash Election or Mixed Election.

   Your election is subject to certain terms, conditions and limitations that
have been set out in the Agreement and the Joint Proxy Statement/Prospectus.
The Agreement is included as Appendix A to the Joint Proxy
Statement/Prospectus. Extra copies of the Joint Proxy Statement/Prospectus may
be requested from Beacon Hill Partners, Inc., the Information Agent, at the
phone number shown above, or from American Stock Transfer & Trust Company, the
Exchange Agent, at the address shown above. The delivery of this Form of
Election and Letter of Transmittal to the Exchange Agent is acknowledgment of
receipt of the Joint Proxy Statement/Prospectus.

   1. Election Deadline. For any Cash Election or Mixed Election contained
herein to be considered, this Form of Election and Letter of Transmittal,
properly completed, and your Century Class B stock certificate(s) must be
received by the Exchange Agent at the address shown above on this Form of
Election and Letter of Transmittal no later than 5:00 p.m., New York City
Time, on September 30, 1999. The Exchange Agent will determine whether any
Form of Election and Letter of Transmittal is received on a timely basis and
whether a Form of Election and Letter of Transmittal has been properly
completed. Any such determinations shall be conclusive and binding.

   The Election Deadline is 5:00 p.m., New York City time, on September 30,
1999.

   2. Effect of Asserting Dissenters' Rights. A Form of Election will not be
valid and will be ignored if completed by a holder of Century Class B Shares
that provides Century (and Century actually receives) written notice of intent
to assert dissenters' rights and does not vote in favor of the Merger and
takes such other actions as may be required prior to the Effective Time to
perfect dissenters' rights under applicable law. Any such holder that
subsequently fails to perfect dissenters' rights will receive $11.81417001 in
cash and 0.63595483 of a share of Adelphia Class A common stock, without
interest in exchange for each share of Century Class B common stock.

   3. Revocation or Change of Form of Election and Letter of Transmittal. Any
Form of Election and Letter of Transmittal may be revoked or changed by
written notice to the Exchange Agent from the person submitting such Form of
Election and Letter of Transmittal, but to be effective such notice must be
received by the Exchange Agent at or prior to the Election Deadline. The
Exchange Agent will have reasonable discretion to determine whether any
revocation or change is received on a timely basis and whether any such
revocation or change has been properly made. Any such determinations shall be
conclusive and binding.

   4. Election Procedures/Proration. To properly complete Box A, (1) the
undersigned must check either the Cash Election, Mixed Election or Stock
Election (if no box is checked, the Stock Election box will be deemed to have
been checked); (2) the name and address of the registered holder(s) must be
set forth in the column under the heading "Name and Address of Registered
Holder(s);" (3) the number of each Century Class B Share

                                       8
<PAGE>

Certificate surrendered herewith must be written in the column under the
heading "Certificate Number" along with the total number of Century Class B
Shares represented by such certificate(s) under the heading "Total Number of
Shares," and (4) in the event of a Mixed Election, the number of Century Class
B Shares to receive cash under the heading "Shares to Receive Cash
Consideration" and the number of Century Class B Shares to receive Adelphia
Class A common stock under the heading "Shares to Receive Stock
Consideration." As set forth in the Joint Proxy Statement/Prospectus, no more
than 24.54% of the outstanding Century Class B Shares (other than shares held
by dissenting stockholders and Century-held Shares) will be exchanged for cash
and no more than 75.46% of such outstanding Century Class B Shares will be
exchanged for Adelphia Class A common stock. If the Elections result in an
oversubscription of either the Cash Consideration or the Stock Consideration,
the procedures for allocating the Merger Consideration set forth in the
Agreement and described in the Joint Proxy Statement/Prospectus will be
followed by the Exchange Agent. Accordingly, there can be no assurance that a
Cash Election, Mixed Election or Stock Election made by you will result in
your receipt of the desired type and amount of Merger Consideration. See the
Joint Proxy Statement/Prospectus under the caption "The Merger Agreement and
Related Agreements--The Merger Agreement--Election; Conversion of Century
Shares; Proration" and "--Proration." The effectiveness of Elections that are
accompanied by Guarantees of Delivery may not be finally determined until
three Nasdaq National Market trading days after the Election Deadline. The
Merger Consideration is expected to be mailed promptly after the determination
of any proration in the Merger.

   5. Termination of Merger Agreement. Consummation of the Merger is subject
to the required approval of the stockholders of Century and Adelphia and to
the satisfaction of certain other conditions. No payments related to any
surrender of Century Class B Share Certificates will be made prior to the
consummation of the Merger, and no payments will be made if the Merger
Agreement is terminated. If the Merger Agreement is terminated, all Century
Class B Elections will be void and of no effect and the Exchange Agent will
promptly return all Century Class B Share Certificates previously received by
it. In such event, Century Class B Shares held through The Depository Trust
Company are expected to be available for sale or transfer promptly following
such termination. Certificates representing Century Class B Shares held of
record directly by the beneficial owners of such Century Class B Shares will
be returned by the Exchange Agent without charge to the holder as promptly as
practicable by first class, insured mail.

   6. No Fractional Interests. No certificate representing fractional shares
of Adelphia Class A common stock will be issued to holders of Century Class B
Shares. Upon surrender of certificates representing Century Class B Shares
after the Merger, holders of Century Class B Shares will be paid cash instead
of any fractional shares of Adelphia Class A common stock they would otherwise
receive. All fractional shares of Adelphia Class A common stock that a holder
of shares of Century Class B Shares otherwise would be entitled to receive as
a result of the merger will be aggregated. If a fractional share results from
such aggregation, the amount of cash to be received instead of the fractional
share will be equal to:

  .  the fraction of a share that would otherwise be received multiplied by

  .  the closing price of a share of Adelphia Class A common stock on the
     Nasdaq National Market on the trading day immediately preceding the
     effective date of the Merger.

   7. Guarantee of Signatures. Signatures on this Form of Election and Letter
of Transmittal need not be guaranteed unless the "Special Issuance and Payment
Instructions" section has been completed and payment is to be made to someone
other than the registered holder(s) of Century Class B Shares with respect to
the surrendered certificates. In such event, signatures on this Form of
Election and Letter of Transmittal must be guaranteed by a financial
institution (including most commercial banks, savings and loan associations
and brokerage houses) that is a participant in the Security Transfer Agent's
Medallion Program, the New York Share Exchange Medallion Program or the Share
Exchange Medallion Program. Public notaries cannot execute acceptable
guarantees of signatures.

   8. Delivery of Form of Election and Letter of Transmittal and Century Class
B Share Certificates; Guarantee of Delivery. This Form of Election and Letter
of Transmittal, properly completed and duly

                                       9
<PAGE>

executed, together with your Century Class B Share Certificate(s) or a
Guarantee of Delivery, should be delivered to the Exchange Agent at the
address set forth above. All Century Class B Share Certificates held by a
single stockholder and not by a nominee, trustee or other representative (as
set forth in General Instruction 9) must all be on a single Letter of
Transmittal. A Guarantee of Delivery of such Century Class B Share
Certificate(s) must be made by a firm which is a member of a registered
national securities exchange or of the National Association of Securities
Dealers, Inc. or a commercial bank or trust company having an office or
correspondent in the United States, and any Century Class B Share
Certificate(s) covered by a Guarantee of Delivery must in fact be delivered to
the Exchange Agent within three Nasdaq National Market trading days after the
date of execution of such Guarantee of Delivery. Failure to deliver such
Century Class B Share Certificate(s) shall invalidate any Election, and a
Stock Election shall be deemed to have been made by the Century Class B Shares
covered thereby. The method of delivery of the Form of Election and Letter of
Transmittal, the Century Class B Share Certificates and all other required
documents is at the election and risk of the holder of Century Class B Shares.
If you choose to send the materials by mail, it is recommended that they be
sent by registered mail, appropriately insured, with return receipt requested.
Delivery of the materials will be deemed effective, and risk of loss with
respect thereto will pass, only when such materials are actually received by
the Exchange Agent. By delivering certificates for Century Class B Shares, the
registered holder of such certificates releases Century, Merger Sub and their
respective affiliates, directors, officers, employees, partners, agents,
advisors and representatives, and their respective successors and assigns,
from any and all claims arising from or in connection with the purchase or
ownership of such Century Class B Shares or the sale thereof or receipt of
shares of common stock of the surviving corporation pursuant to the Agreement.

   9. Shares Held By Nominees, Trustees or Other Representatives; Multiple
Elections. Holders of record of Century Class B Shares who hold such shares as
nominees, trustees or in other representative or fiduciary capacities (a
"Representative") may submit one or more Forms of Election and Letters of
Transmittal covering the aggregate number of Century Class B Shares held by
such Representative for the beneficial owners for whom the Representative is
making an affirmative Cash Election, Mixed Election or Stock Election or a
deemed Stock Election, provided that such Representative certifies that each
Form of Election and Letter of Transmittal covers all of the Century Class B
Shares held by such Representative for any single beneficial owner. Any
Representative that makes an affirmative Cash Election, Mixed Election or
Stock Election or a deemed Stock Election may be required to provide the
Exchange Agent with such documents and/or additional certifications, if
requested, in order to satisfy the Exchange Agent that such Representative
holds such Century Class B Shares for a particular beneficial owner. If any
Century Class B Shares are not covered by an effective Form of Election and
Letter of Transmittal, they will be deemed to be covered by a deemed Stock
Election.

   10. Inadequate Space. If the space provided herein is inadequate, the share
certificate numbers and the numbers of Century Class B Shares represented
thereby should be listed on additional sheets and attached hereto.

   11. Signatures on Form of Election and Letter of Transmittal, Stock Powers
and Endorsements.

   (a) All signatures must correspond exactly with the name written on the
face of the certificate(s) without alteration, variation or any change
whatsoever.

   (b) If the certificate(s) surrendered is (are) held of record by two or
more joint owners, all such owners must sign this Form of Election and Letter
of Transmittal.

   (c) If any surrendered Century Class B Shares are registered in different
names on several certificates, it will be necessary to complete, sign and
submit as many separate Forms of Election and Letters of Transmittal as there
are different registrations of certificates.

   (d) If this Form of Election and Letter of Transmittal is signed by a
person(s) other than the record holder(s) of the certificates listed (other
than as set forth in paragraph (e) below), such certificates must be endorsed
or accompanied by appropriate stock powers, in either case signed exactly as
the name(s) of the record holder(s) appears on such certificate(s).


                                      10
<PAGE>

   (e) If this Form of Election and Letter of Transmittal is signed by a
trustee, executor, administrator, guardian, attorney-in-fact, officer of a
corporation or other person acting in a fiduciary or representative capacity
and such person is not the record holder of the accompanying certificates, he
or she must indicate the capacity when signing and must submit proper evidence
of his or her authority to act.

   12. Stock Transfer Taxes. In the event that any transfer or other taxes
become payable by reason of the issuance of the Merger Consideration in any
name other than that of the holder of Century Class B Shares, such transferee
or assignee must pay such tax to the Exchange Agent or must establish to the
satisfaction of the Exchange Agent that such tax has been paid.

   13. Special Issuance And Delivery Instructions. In the "Special Issuance
and Payment Instructions" box, indicate the name and/or address of the
person(s) to whom the Merger Consideration is to be issued and mailed only if
the Merger Consideration (whether cash or Adelphia Class A common stock) is to
be issued in the name of someone other than the person(s) signing this Form of
Election and Letter of Transmittal. If the "Special Issuance and Payment
Instructions" box is completed, the Exchange Agent will issue the Merger
Consideration in the name of, and will mail the Merger Consideration to, the
person or entity so indicated at the address so indicated, but only after the
Exchange Agent has been provided with satisfactory evidence of the payment of,
or exemption from payment of, any applicable stock transfer taxes payable on
account of the transfer to such person or entity prior to the delivery of the
Merger Consideration.

   In the "Special Delivery Instructions" box, indicate the address to which
the Merger Consideration is to be mailed in the name of the undersigned only
if different from the address set forth in Box A.

   14. Withholding. Each surrendering holder of Century Class B Shares is
required to provide the Exchange Agent with such holder's correct Taxpayer
Identification Number ("TIN") on the Substitute Form W-9 and to certify
whether such holder is subject to backup withholding. The TIN that must be
provided is that of the holder of Century Class B common stock with respect to
the certificate(s) surrendered herewith or of the last transferee appearing on
the transfers attached to or endorsed on such certificate(s) (or, if a check
is made payable to another person as provided in the box above entitled
"Special Issuance and Payment Instructions," then the TIN of such person).
Failure to provide the information on the Substitute Form W-9 may subject the
surrendering holder of Century Class B common stock to 31% federal income tax
withholding on payments made to such surrendering holder with respect to the
Century Class B Shares and on future dividends, if any, paid by Adelphia. A
holder of Century Class B common stock must cross out item (2) in the
certification box of Substitute Form W-9 if such holder has been notified by
the Internal Revenue Service ("IRS") that such holder is currently subject to
backup withholding. The box in Part 3 of the Substitute Form W-9 should be
checked if the surrendering holder of Century Class B common stock has not
been issued a TIN and has applied for a TIN or intends to apply for a TIN in
the near future. If the box in Part 3 is checked and the Exchange Agent is not
provided with a TIN, Adelphia will withhold 31% of all such payments and
dividends but will return such amounts to the holder of Century Class B common
stock if a TIN is later provided to the Exchange Agent within 60 days. Foreign
investors should consult their tax advisors regarding the need to complete IRS
Form W-8 and any other forms that may be required.

   15. Lost, Stolen or Destroyed Certificates. You cannot submit an effective
Form of Election and Letter of Transmittal without attaching your
certificate(s) to this Form of Election and Letter of Transmittal. If your
certificate(s) has (have) been lost, stolen or destroyed, you are urged to
call the Information Agent toll-free at (800) 755-5001 immediately to receive
instructions as to the steps you must take in order to effect an exchange of
your Century Class B Shares.

   16. Elections, Certificates and Share Allocations. Each holder of Century
Class B Shares is entitled to make a Cash Election, a Stock Election or a
Mixed Election, provided the Form of Election and Letter of Transmittal for
any holder making a Cash Election or a Mixed Election is properly completed
and received by the Exchange Agent prior to the Election Deadline of 5:00
p.m., New York City time, on September 30, 1999. All holders of Century Class
B common stock must complete Box A in order to effect a Cash Election or Mixed

                                      11

Election. To properly complete Box A, the number of each certificate
surrendered herewith must be written in the column under the heading
"Certificate Number." In the event such holder is making a Cash Election as to
all shares, the box immediately to the left of the words "Cash Election" must
be checked, the number of Century Class B Shares represented by each
certificate surrendered herewith should be written into the column under the
heading "Shares to Receive Cash Consideration" beside each certificate number,
and the column under the heading "Shares to Receive Stock Consideration"
should be left blank. In the event such holder is making a Stock Election as
to all shares, the box immediately to the left of the words "Stock Election"
may be checked (although all Forms of Election and Letters of Transmittal that
are improperly completed or that do not specify an election will be deemed to
have specified a Stock Election as to all shares), the number of Century Class
B Shares represented by each certificate surrendered herewith should be
written into the column under the heading "Shares to Receive Stock
Consideration" beside each certificate number, and the column under the
heading "Shares to Receive Cash Consideration" should be left blank. In the
event such holder is making a Mixed Election, the box immediately to the left
of the words "Mixed Election" should be checked and such holder should
allocate his or her shares represented by such holder's certificates between
the columns marked "Shares to Receive Stock Consideration" and "Shares to
Receive Cash Consideration" according to such holder's preferences. Holders of
Century Class B Shares should see "Important Tax Information" below for
important tax consequences of various elections.

                           IMPORTANT TAX INFORMATION

   Withholding. Under the federal income tax law, the Exchange Agent is
required to file a report with the IRS disclosing any payments of cash being
made to each holder of certificates pursuant to the Merger Agreement and to
impose 31% backup withholding if required. If the correct certifications on
Substitute Form W-9 are not provided, a $50 penalty may be imposed by the IRS
and payments made for Century Class B Shares may be subject to backup
withholding of 31%. Backup withholding is also required if the IRS notifies
the recipient that they are subject to backup withholding as a result of a
failure to report all interest and dividends.

   In order to avoid backup withholding resulting from a failure to provide a
correct certification, a holder of Century Class B Shares must, unless an
exemption applies, provide the Exchange Agent with his correct TIN on
Substitute Form W-9 as set forth on this Form of Election and Letter of
Transmittal. Such person must certify under penalties of perjury that such
number is correct and that such holder is not otherwise subject to backup
withholding. The TIN that must be provided is that of the registered holder of
the Century Class B Share Certificate(s) or of the last transferee appearing
on the transfers attached to or endorsed on the Century Class B Share
Certificate(s) (or, if a check is made payable to another person as provided
in the box entitled "Special Issuance and Payment Instructions," then the TIN
of such person). Foreign investors should consult their tax advisors regarding
the need to complete IRS Form W-8 and any other forms that may be required.

   Backup withholding is not an additional federal income tax. Rather, the
federal income tax liability of a person subject to backup withholding will be
reduced by the amount of tax withheld. If backup withholding results in an
overpayment of taxes, a refund may be obtained from the IRS.

   Please read the enclosed Guidelines for Certification of Taxpayer
Identification Number on Substitute Form W-9 for additional important
information on how to complete the Substitute Form W-9.

   For a summary of the federal income tax consequences of the receipt of the
Merger Consideration, see "The Merger--Material Federal Income Tax
Consequences" in the Joint Proxy Statement/Prospectus.

                         [Letterhead of Century Comm.]
August 12, 1999

Dear Century Stockholder:

   It is currently anticipated that the merger (the "Merger") of Century
Communications Corp. ("Century") with and into Adelphia Acquisition Subsidiary,
Inc. ("Merger Sub"), a wholly owned subsidiary of Adelphia Communications
Corporation ("Adelphia"), will, subject to stockholder approval and other
closing conditions, be consummated subsequent to the special meetings.

   In accordance with the terms of the agreement and plan of merger, as amended
(the "Merger Agreement"), you may surrender the stock certificate(s)
representing all of your Century Class B Shares in exchange for certificates
representing shares of Class A common stock of Adelphia at an exchange ratio of
0.84271335 of a share of Adelphia Class A common stock for each Century Class B
Share, subject to the proration procedure as described below. The Merger
Agreement also allows you to elect to receive on a share by share basis, in
lieu of Adelphia Class A common stock, $48.14 in cash for all or a portion of
your Century Class B Shares, subject to the proration procedure as described
below, or a combination of cash and Adelphia Class A common stock. Pursuant to
the terms of the Merger Agreement, the aggregate number of Century Class B
Shares that may be converted into the right to receive cash will not exceed
24.54% of the number of Century Class B Shares outstanding immediately prior to
the Effective Time of the Merger (excluding dissenting stockholders) and the
aggregate number of Century Class B Shares that may be converted into the right
to receive shares of Adelphia Class A common stock will not exceed 75.46% of
the number of Century Class B Shares outstanding immediately prior to the
Effective Time (excluding dissenting stockholders). Stockholders of Century who
elect to receive cash should be aware that they may receive some shares of
Adelphia Class A common stock instead of cash in the Merger and stockholders of
Century who elect to receive stock should be aware that they may receive some
cash instead of Adelphia Class A common stock in the Merger.

   As of the effective date of the Merger, your certificate(s) for Century
Class B Shares automatically will be deemed to evidence ownership of the number
of shares of Adelphia Class A common stock into which such Century Class B
Shares have been converted, if you did not elect cash. However, no such
dividends or other distributions (if any) made with respect to your Adelphia
Class A common stock will be distributed until your certificate(s) for Century
Class B Shares have been surrendered for exchange and a properly completed blue
Form of Election and Letter of Transmittal has been submitted. Therefore, we
encourage you to exchange your certificate(s) as soon as possible.

   A blue Form of Election and Letter of Transmittal and related instructions,
together with a return envelope are enclosed for your use in delivering or
mailing your certificates to American Stock Transfer & Trust Company, the
Exchange Agent for this transaction. The blue Form of Election and Letter of
Transmittal must be properly executed and returned with your certificates. If
you elect all or a portion of the consideration for your shares in cash, your
Form of Election and Letter of Transmittal and certificates must be received by
5:00 p.m., New York City time, on September 30, 1999. Please read the Form of
Election and Letter of Transmittal carefully, along with the General
Instructions.

   We urge you to act promptly in this matter. If you have any questions,
please contact American Stock Transfer & Trust Company, the Exchange Agent,
toll-free at (800) 937-5449 or Beacon Hill Partners, the Information Agent,
toll-free at (800) 755-5001.

                                             Sincerely,
                                             /s/ Leonard Tow

                                             of the Board and Stockholder
