                                 Statement of

                           TELE-COMMUNICATIONS, INC.

                       Pursuant to Section 13(d) of the
                        Securities Exchange Act of 1934

                                 in respect of

                      ADELPHIA COMMUNICATIONS CORPORATION
                        (Commission File No. 000-16014)


ITEM 1.   Security and Issuer
          -------------------

          Tele-Communications, Inc., a Delaware corporation ("TCI"), is filing
this Statement on Schedule 13D (this "Statement") with respect to the Class A
Common Stock, par value $.01 per share (the "Common Stock"), of Adelphia
Communications Corporation, a Delaware corporation (the "Issuer").  The Issuer's
principal executive offices are located at Main at Water Street, Coudersport,
Pennsylvania, 16915.


ITEM 2.   Identity and Background
          -----------------------

          The reporting person is TCI, whose principal business address is 5619
DTC Parkway, Englewood, Colorado 80111.

          TCI, through its subsidiaries and affiliates, is principally engaged
in the construction, acquisition, ownership, and operation of cable television
systems and the provision of satellite-delivered video entertainment,
information and home shopping programming services to various video distribution
media, principally cable television systems.  TCI also has investments in cable
and telecommunications operations and television programming in certain
international markets as well as investments in companies and joint ventures
involved in developing and providing programming for new television and
telecommunications technologies.  TCI is a Delaware corporation and was
incorporated in 1994.  TCI Communications, Inc. ("TCIC"), a majority owned
subsidiary of TCI, and its predecessors have been engaged in the cable
television business since the early 1950's.  Prior to August 1994, TCI was named
TCI/Liberty Holding Company and TCIC was named Tele-Communications, Inc.

          Schedule 1 attached to this Statement contains the following
information concerning each director, executive officer and controlling person
of TCI:  (i) name and residence or business address, (ii)  principal occupation
or employment; and (iii) the name, principal business and address of any
corporation or other organization in which such employment is conducted.
Schedule 1 is incorporated herein by reference.

          To the knowledge of TCI, each of the persons named on Schedule 1 (the
"Schedule 1 Persons") is a United States citizen.  During the last five years,
neither TCI nor any of the Schedule 1 Persons (to the knowledge of TCI) has been
convicted in a criminal proceeding (excluding traffic violations 

                                    3 of 69
<PAGE>
 
or similar misdemeanors). During the last five years, neither TCI nor any of the
Schedule 1 Persons (to the knowledge of TCI) has been a party to a civil
proceeding of a judicial or administrative body of competent jurisdiction and,
as a result of such proceeding, is or was subject to a judgment, decree or final
order enjoining future violations of, or prohibiting or mandating activities
subject to, federal or state securities laws or finding any violation with
respect to such laws.

ITEM 3.   Source and Amount of Funds or Other Consideration
          -------------------------------------------------

          TCI currently beneficially owns, through its wholly-owned subsidiary
TCI Development Corporation ("TCID"), a total of 2,250,000 shares of Common
Stock. TCID acquired such shares of Common Stock pursuant to the terms of an
Agreement and Plan of Merger (the "Agreement"), dated as of August 31, 1998, by
and among TCID-SVHH, Inc., a Delaware Corporation (and, prior to the
consummation of the merger pursuant to the Agreement (the "Merger"), a wholly-
owned subsidiary of TCID) (hereinafter, the "Company"), SHHH Acquisition Corp.
(the "Merger Subsidiary"), TCID, and the Issuer.  The Company owns the Class A
Limited Partner interest (the "Partnership Interest") in Syracuse Hilton Head
Holdings, L.P., a Delaware limited partnership existing and operating under the
Amended and Restated Syracuse Hilton Head Holdings, L.P. Limited Partnership
Agreement dated as of December 31, 1991, as amended.  In accordance with the
Agreement, the Issuer issued 2,250,000 shares of Common Stock to TCID in
consideration for the merger of Merger Subsidiary with and into the Company,
with the Company surviving (the Company, post-Merger, is hereinafter sometimes
referred to as the "Surviving Corporation").  Pursuant to the Merger, the
outstanding capital stock of the Company was canceled and converted into
2,250,000 shares of Common Stock, while each share of common stock of the Merger
Subsidiary outstanding prior to the Merger was converted into one share of
common stock of the Surviving Corporation.  As a result of the Merger, TCID
became the owner of 2,250,000 shares of Common Stock of the Issuer, and the
Issuer, through the Surviving Corporation, became the owner of the Partnership
Interest.

          The foregoing summary of the terms of the Agreement is qualified in
its entirety by reference to the text of the Agreement, filed as Exhibit 7(a) to
this Statement, and the Adelphia Communications Corporation Registration Rights
Agreement, dated as of September 30, 1998, between TCID and Issuer (the
"Registration Rights Agreement"), filed as Exhibit 7(b) to this Statement, which
Exhibits are incorporated herein by this reference.

ITEM 4.   Purpose of Transaction
          ----------------------

          TCI currently holds its interest in the Issuer for investment
purposes.  Neither TCI nor, to the best of its knowledge, any of its executive
officers, directors or controlling persons has any present plans or proposals
which relate to or would result in:  (i) any acquisition by any person of
additional securities of the Issuer, or any disposition of securities of the
Issuer, (ii) any extraordinary corporate transaction, such as a merger,
reorganization or liquidation, involving the Issuer or any of its subsidiaries;
(iii) any sale or transfer of a material amount of assets of the Issuer or any
of its subsidiaries; (iv) any change in the present board of directors or
management of the Issuer, including any plans or proposals to change the number
or term of directors or to fill any existing vacancies on the board; (v) any
material change in the present capitalization or dividend policy of the Issuer;
(vi) any other material change in the Issuer's business or corporate structure;
(vii) any changes in the Issuer's charter, by-laws, or other instruments
corresponding thereto or other actions which may impede the acquisition of
control of the Issuer by any person; (viii) any delisting from a national
securities exchange or any loss of authorization for quotation in an inter-
dealer quotation system of a registered national securities association of a
class of securities of the Issuer; (ix) any termination of registration pursuant
to section 12(g)(4) of the Securities Exchange Act of 1934, as amended, of a
class of equity securities of the Issuer; or (x) any action similar to any of
those enumerated above.

                                    4 of 69
<PAGE>
 
          Notwithstanding the foregoing, TCI may determine to change its
investment intent with respect to the Issuer at any time in the future.  In
reaching any conclusion as to its future course of action, TCI will take into
consideration various factors, such as the Issuer's business and prospects,
other developments concerning the Issuer, other business opportunities available
to TCI, developments with respect to the business of TCI, and general economic
and stock market conditions, including, but not limited to, the market price of
the Common Stock of the Issuer.  TCI reserves the right, depending on other
relevant factors, to acquire additional shares of the Common Stock of Issuer in
the open market or in privately negotiated transactions, to dispose of all or a
portion of its holdings of shares of the Common Stock of the Issuer, or to
change its intention with respect to any or all of the matters referred to in
this Item.


ITEM 5.   Interest in Securities of the Issuer
          ------------------------------------

          (a) TCI presently beneficially owns, through its wholly-owned
subsidiary TCID, 2,250,000 shares of Common Stock. The 2,250,000 shares of
Common Stock beneficially owned by TCI represent 7.2% of the sum of such shares
and the shares of the Common Stock outstanding as of September 22, 1998.

          To the knowledge of TCI, none of the Schedule 1 Persons has any
interest in any securities of the Issuer.

          (b) TCI, through its subsidiary, TCID, has sole power to vote or to
direct the voting of the shares of the Common Stock that TCI beneficially owns
and sole power to dispose of, or to direct the disposition of, such shares of
Common Stock.

          (c) Except for the securities of the Issuer acquired in connection
with the transaction described in Item 3 hereof, neither TCI nor, to the
knowledge of TCI, any of the persons named on Schedule 1, has executed
transactions in the Common Stock of the Issuer during the past sixty (60) days.
 
          (d) There is no person that has the right to receive or the power to
direct the receipt of dividends from, or the proceeds from the sale of, the
Common Stock beneficially owned by TCI.

          (e)  Not applicable.


ITEM 6.   Contracts, Arrangements, Understandings or Relationships with Respect
          ---------------------------------------------------------------------
to Securities of the Issuer
- ---------------------------

          In accordance with the terms of the Agreement, TCI, through TCID,
acquired 2,250,000 shares of Common Stock in connection with the Merger.  TCID
acquired ownership of the Common Stock from the Issuer on September 30, 1998.

          In connection with the Merger, the Issuer and TCID entered into the
Registration Rights Agreement, pursuant to which the  Issuer granted TCID
registration rights (the "Registration Rights") for (i) the Common Stock
acquired in connection with the Merger and (ii) any securities of the Issuer
issued as a dividend or other distribution with respect to, or in exchange for
or in replacement of, such Common Stock (collectively, the "Registrable
Securities").  The Registration Rights are transferable only to a wholly-owned
subsidiary of TCI or any successor to TCI pursuant to a merger, consolidation,
or otherwise (the "Holder").  The Registration Rights are exercisable, on demand
at any time after the first anniversary of the date of the Registration Rights
Agreement, as to any of the Registrable Securities as Holder specifies in its
demand, on a maximum of two occasions; provided, however, that the Issuer shall
not be obligated to effect 

                                    5 of 69
<PAGE>
 
a registration to the extent that the Holders may sell all their Registrable
Securities without being subject to a holding period or volume limitations and
without such Holder being required to deliver a prospectus in connection
therewith under the Securities Act of 1933, as amended (the "Act").
Notwithstanding the foregoing, in the event that, prior to the first anniversary
of the date hereof, TCID is required to dispose of Registrable Securities in
order to decrease the ownership interest attributed to TCID and its affiliates
so that TCID and its affiliates would not be deemed to have an "attributable
interest" in the Company under the horizontal attribution rules of the Federal
Communications Commission, TCID may request the Company to file a Registration
Statement prior to the first anniversary of the date of the Registration Rights
Agreement without such registration counting towards the two demand
registrations otherwise permitted pursuant to such agreement.


          The Issuer may require the Holder not to make any sales pursuant to an
effective Registration Statement for up to two periods of thirty (30) days,
should the Issuer determine that such registration would materially adversely
affect any financing, acquisition, corporate reorganization or other material
transaction or development involving the Issuer or any of its affiliates.  The
Issuer shall cause the registration statement filed in connection with a demand
to be effective continually for one hundred twenty (120) days from the date of
initial effectiveness of such registration statement; however, such period will
be extended by (a) any length of time during which TCID is blocked from selling
the Registrable Securities under specific provisions of the Registration Rights
Agreement, or (b) until the earlier of the date upon which all Registrable
Securities have been sold by the Holder or may be sold by the Holder without
being subject to a holding period or volume limits and without such Holder being
required to deliver a prospectus in connection therewith.  In addition, in
consideration for Issuer's grant of Registration Rights, the Holder agrees, upon
request, to be bound by the terms of any agreement undertaken by directors and
executive officers of Issuer, as well as John J. Rigas and members of Mr. Rigas'
immediate family not to dispose of Issuer Common Stock for a period not to
exceed 120 days from the effective date of such registration, as may be
specified by the Issuer or underwriters.  Finally, the Issuer has agreed that it
will not permit any other holder or prospective holder of its securities to
register such securities on any registration statement filed pursuant to the
Registration Rights Agreement.

          Except as described above and in Item 3 hereof, there are no other
contracts, arrangements, understandings or relationships among TCID and other
persons with respect to the Common Stock of the Issuer.


ITEM 7.   Material to be Filed as Exhibits
          --------------------------------

          (a)  Agreement and Plan of Merger, dated as of September 30, 1998, by

               adjustments, if any, shall be made to the number of shares of

               shall consider or be advised that any deeds, bills of sale,
               assignments or assurances or any other acts or things are
               necessary, desirable or proper (a) to vest, perfect or confirm,

     5.6  SHAREHOLDER REPRESENTATIONS.
          --------------------------- 

          The Shareholder hereby represents and warrants to, and agrees with,
          the Parent as follows:

          (a)  The Shareholder has been furnished with, and has carefully read,
               the information regarding the Parent previously provided,
               including the Parent's Annual Report on Form 10-K for the fiscal
               year ended March 31, 1998 (the "10-K"), Parent's Quarterly Report

               is familiar with and understands the terms of the Merger. With
               respect to tax and other economic considerations involved in this
               investment, the Shareholder is not relying on the Parent (or any
               agent or representative of the Parent). The Shareholder has
               carefully considered and has, to the extent the Shareholder
               believes such discussion necessary, discussed with the
               Shareholder's professional legal, tax, accounting and financial
               advisors the suitability of an investment in the Parent Common
               Stock for the Shareholder 's particular tax and financial
               situation and has determined that the Parent Common Stock is a
               suitable investment for the Shareholder.

          (b)  The Shareholder acknowledges that all documents, records and
               books pertaining to this investment which the Shareholder has
               reasonably requested have been made available for inspection by
               the Shareholder and its adviser(s).

          (c)  The Shareholder and its adviser(s) have had a reasonable
               opportunity to ask questions of and receive answers from a person
               or persons acting on behalf of the Parent concerning the issuance
               of Parent Common Stock in the Merger and all such questions have
               been answered to their full satisfaction.

          (d)  The Shareholder is not subscribing for Parent Common Stock as a
               result of, or subsequent to, any advertisement, article, notice
               or other communication published in any newspaper, magazine or
               similar medium or broadcast over television or radio or presented
               at any seminar or meeting.

          (e)  The Shareholder, by reason of its business or financial
               experience or the business or financial experience of its
               advisers, can be reasonably assumed to have the capacity to

               informed investment decision with respect thereto.

          (h)  The Shareholder acknowledges that the issuance of the Parent
               Common Stock by the Parent to the Shareholder has not been

               Act; and (iii) the Shareholder has not offered or sold any
               portion of the Parent Common Stock being acquired nor does the

               of time or upon the occurrence or nonoccurrence of any
               predetermined event or circumstance. Except as provided in the
               Registration Rights Agreement, the Parent has no obligation to

               amount of such investment.

               the Parent Common Stock shall be stamped or otherwise imprinted

               determination as to the fairness of the terms of this offering of
               Parent Common Stock for investment nor any recommendation or
               endorsement of the Parent Common Stock, and that the issuance of
               the Parent Common Stock in the Merger is intended to be exempt
               from registration under the Securities Act by virtue of Section
               4(2) of the Securities Act and the provisions of Regulation D
               thereunder, which exemptions are in part dependent upon the
               truth, completeness and accuracy of the statements made by the
               Shareholder herein.

     11.3 INDEMNIFICATION WITH RESPECT TO THIRD-PARTY CLAIMS.
          -------------------------------------------------- 

          (a) As used herein, a "Third-Party Claim" means a Loss or potential
              Loss for which indemnification is claimed by Merger Subsidiary or
              Parent or Shareholder (the "Indemnitee") under the provisions of
              this Article 11 and which is consequent to a claim against the
              Indemnitee by a person,

                                       22
<PAGE>
 
              corporation, association, partnership or other entity, or an
              individual, or a government, any political subdivision thereof or
              a governmental agency by commencement against the Indemnitee of a
              legal action or proceeding or receipt by the Indemnitee of an
              assertion of a claim for which indemnification is provided
              pursuant to this Article 11 by Merger Subsidiary and Parent or
              Shareholder, as the case may be (the "Indemnitor").

          (b) The Indemnitee will give notice of a Third-Party Claim to the
              Indemnitor, stating the nature thereof and enclosing copies of any
              complaint, summons, written assertion of such Third-Party Claim or
              similar document. No claim for indemnification on account of a
              Third-Party Claim shall be made and no indemnification therefor
              shall be available under this Article 11 until the Indemnitee
              shall have given initial written notice of its claim to the
              Indemnitor.

          (c) Except as hereinafter provided (including, but not limited to,
              Section 11.3(d)(ii) hereof), the Indemnitor shall engage counsel
              to defend a Third-Party Claim, and shall provide notice to the
              Indemnitee not later than 15 business days following delivery by
              the Indemnitee to the Indemnitor of a notice of a Third-Party
              Claim, such notice to include an acknowledgment by the Indemnitor
              that it will be liable in full to the Indemnitee for any Losses in
              connection with such Third-Party Claim. The Indemnitee will fully
              cooperate with such counsel. The Indemnitor will cause such
              counsel to consult with the Indemnitee as appropriate as to the
              defense of such claim, and the Indemnitee may, at its own expense,
              participate in such defense, assistance or enforcement, but except
              as provided in (d) the Indemnitor shall control such defense,
              assistance or enforcement. The Indemnitor will cause such counsel
              engaged by the Indemnitor to keep the Indemnitee informed at all
              times of the status of such defense, assistance or enforcement.

          (d) (i)  Notwithstanding the provisions of Section 11.3(c), the
                   Indemnitee shall have the right to engage counsel and to
                   control the defense of a Third-Party Claim if the Indemnitor
                   shall not have notified the Indemnitee of its appointment of
                   counsel and control of the defense of a Third-Party Claim
                   pursuant to Section 11.3(c) within the time period therein
                   provided.

              (ii) Notwithstanding the engagement of counsel by the Indemnitor,
                   the Indemnitee shall have the right, at its own expense, to
                   engage counsel to participate jointly with the Indemnitor in,
                   and to control jointly with the Indemnitor, the defense of a
                   Third-Party Claim if (x) the Third-Party Claim involves
                   remedies other than monetary damages and such remedies, in
                   the Indemnitee's reasonable

                                       23
<PAGE>
 
                     judgment, could have an ongoing effect on the conduct of
                     the Indemnitee's business, or (y) the Third-Party Claim
                     relates to acts, omissions, conditions, events or other
                     matters occurring after the Closing Date as well as to
                     acts, omissions, conditions, events or other matters
                     occurring prior to the Closing Date.

               (iii) If the Indemnitee chooses to exercise its right to appoint
                     counsel under this Section 11.3(d), the Indemnitee shall
                     deliver notice thereof to the Indemnitor setting forth in
                     reasonable detail why it believes that it has such right
                     and the name of the counsel it proposes to employ. The
                     Indemnitee may deliver such notice at any time that the
                     conditions to the exercise of such right appear to be
                     fulfilled, it being recognized that in the course of
                     litigation, the scope of litigation and the amount at stake
                     may change. The Indemnitee shall thereupon have the right
                     to appoint such counsel.

               (iv)  The reasonable fees and expenses of counsel and any
                     accountants, experts or consultants engaged by the
                     Indemnitee in accordance with the provisions of Section
                     11.3(d)(i) in connection with defending a Third-Party Claim
                     shall be paid by the Indemnitor in accordance with the
                     provisions of this Article 11. If the Indemnitee's
                     employment of counsel is for a Third-Party Claim of the
                     type described in subdivision (ii)(y) of this Section
                     11.3(d), then subject to the provisions of Section 11.3(e),
                     the amount of fees and expenses so payable by the
                     Indemnitor shall be that fraction of the aggregate of such
                     fees and expenses, the numerator of which is the portion of
                     the amount of any judgment on, or settlement of, such Third
                     Party Claim for which the Indemnitee is indemnified
                     pursuant to this Article 11 and the denominator of which is
                     the total amount of such judgment or settlement, but
                     provided further, if such defense of a Third-Party Claim is
                     ----------------
                     successful (in the sense that as a consequence thereof,
                     there is no Loss (other than such fees and expenses) for
                     which the Indemnitee is indemnified pursuant to this
                     Article 11), the Indemnitee and the Indemnitor will attempt
                     in good faith to reach an agreement on the amount of such
                     fees and expenses so payable by the Indemnitor.

 

          (e)  (i)   The Indemnitor may, without the Indemnitee's consent,
                     settle any Third-Party Claim solely involving monetary
                     damages only if the amount of such settlement is to be paid
                     entirely by the Indemnitor pursuant to this Article 11.

               (ii)  The Indemnitor will not enter into a settlement of a Third-
                     Party Claim which involves a non-monetary remedy against
                     the Indemnitee or which will not be paid entirely by the
                     Indemnitor

                     pursuant to this Article 11 without the written consent of
                     the Indemnitee (which consent shall not be unreasonably
                     withheld, delayed or conditioned).

               (iii) The Indemnitee will not enter into a settlement of a Third-
                     Party Claim without the written consent of the Indemnitor,
                     which consent shall not be unreasonably withheld, under the
                     circumstances described in subdivision (i) of Section
                     11.3(d), if the Indemnitor has accepted all or any portion
                     of the liability for such Third-Party Claim. Otherwise, the
                     Indemnitee shall be free to compromise, defend and settle
                     Third-Party Claims without prejudice to any of its rights
                     hereunder or under applicable law.

               (iv)  As to any Third-Party Claim of the type described in
                     subsection (ii)(y) of Section 11.3(d), the Indemnitee and
                     the Indemnitor shall consult as to any proposed settlement.
                     If the Indemnitee notifies the Indemnitor that it wishes to
                     accept a proposed settlement and the Indemnitor is
                     unwilling to do so, if the amount for which the Third-Party
                     Claim is ultimately resolved is greater than the amount for
                     which the Indemnitee could have settled such claim, then
                     (x) the Indemnitee shall be liable only for the amount, if
                     any, which it would have paid had the Third-Party Claim
                     been settled as proposed by the Indemnitee, and (y) all
                     reasonable attorneys' fees and expenses and costs of suit
                     incurred by the Indemnitee subsequent to the time of the
                     proposed settlement shall be paid or reimbursed by the
                     Indemnitor.

               (v)   In determining whether to accept or reject any settlement
                     proposal, each party shall act in good faith.

          (f)  Notwithstanding the foregoing, in the event of any settlement of,
               or final judgment with respect to, a Third-Party Claim which
               relates to acts, omissions, conditions, events or other matters
               occurring both before and after the Closing Date, the Indemnitee
               and the Indemnitor shall negotiate in good faith as to the
               portion of such Third-Party Claim as to which such
               indemnification is payable.

          (g)  The Indemnitee and the Indemnitor shall cooperate with one
               another in good faith in connection with the defense, compromise
               or settlement of any claim or action. Without limiting the
               generality of the foregoing, each party participating in the
               defense or settlement of any matter shall take steps reasonably
               designed to ensure that the other party and its counsel are
               informed at all times of the status of such matter. Neither party
               shall dispose of, compromise or settle any claim or action in a
               manner that is not reasonable under the circumstances and in good
               faith. The Indemnitor

                                       25
<PAGE>
 
               and Indemnitee shall enter into such confidentiality and other
               non-disclosure agreements as the Indemnitee or Indemnitor, as the
               case may be, shall reasonably request in order to protect trade
               secrets and other confidential or proprietary information of the
               Indemnitee or Indemnitor, as the case may be.

16.  OTHER COVENANTS.
     --------------- 

     16.1 TAX RETURNS.
          ----------- 

          (a) Shareholder will be responsible for the preparation and filing of
              all tax returns of Company for all periods ending on or before the
              Closing Date. The federal income, deductions and credits with
              respect to Company on such returns will be computed consistent
              with past practices, principles and methods. Prior to filing any
              such return for a taxable period ending on or before the Closing
              Date, Shareholder will submit such returns (if the return is a
              separate return of Company or if such return is a consolidated
              return, information regarding the reporting of income, deductions
              and credits with respect to Company shall be provided to
              Shareholder rather than the consolidated return) to Merger
              Subsidiary for its review, provided that Merger Subsidiary's
              approval of such returns or information will not be required.

          (b) Surviving Corporation will prepare or cause to be prepared and
              file or cause to be filed any tax returns of Company for tax
              periods which begin before the Closing Date and end after the
              Closing Date. Prior to filing any such return, Surviving
              Corporation shall submit such return to Shareholder for its
              review, provided that Shareholder's approval of such return will
              not be required. Shareholder will pay to Surviving Corporation
              within fifteen days after the date on which taxes are paid (e.g.
              the original due date of the return) with respect to such periods
              an amount equal to the portion of such taxes which relate to the
              portion of such taxable period ending on the Effective Time based
              on the closing of the books of Company at the Effective Time.

          (c) If any dispute arises regarding the amount of taxes payable by
              Shareholder, the parties shall engage Price Waterhouse Coopers
              (the "Independent Accountant") to resolve the dispute and shall
              direct the Independent Accountant in the terms of the engagement
              that the dispute is required to be resolved within thirty (30)
              days after such engagement. The Independent Accountant's
              determination shall be final and binding on the parties. All fees
              and costs of the Independent Accountant shall be borne pro rata by
              Shareholder and Surviving Corporation in proportion to the
              difference between the Independent Accountant's determination of
              the correct amount of taxes payable by Shareholder and each of
              Surviving Corporation's and Shareholder's determination of such
              amount. Pending the Independent Accountant's resolution of any
              dispute submitted to it pursuant to this Section 16.1(c),
              Shareholder shall pay to Surviving Corporation the amount of taxes
              that Shareholder believes it is required to pay. Shareholder shall
              pay to Surviving Corporation any additional taxes determined by
              the Independent Accountant to be payable by it within 30

                                       29
<PAGE>
 
              days after the Independent Accountant delivers to Shareholder and
              Surviving Corporation a written report detailing its determination
              and the basis therefor. The tax returns filed by Surviving
              Corporation prior to the Independent Accountant's resolution of
              the dispute shall be amended by the Surviving Corporation as
              necessary to reflect the Independent Accountant's determination.

          (d) Shareholder, Parent and Surviving Corporation shall cooperate
              fully, to the extent reasonably requested by the other party, in
              connection with the filing of tax returns pursuant to this Section
              and any audit, litigation or proceeding with respect thereto.

     16.2 TAX FREE REORGANIZATION.
          ----------------------- 

          Merger Subsidiary, Parent, Company and Shareholder intend that the
          transactions contemplated by this Agreement constitute a tax-free
          reorganization within the meaning of Section 368(a) of the Code and
          will file all tax returns in a manner consistent therewith.  Neither
          Parent nor Merger Subsidiary shall take or cause to be taken any
          action that would disqualify the Merger as a "reorganization" within
          the meaning of Section 368(a) of the Code.

     16.3 INDEMNIFICATION OF EXECUTIVES.
          ----------------------------- 

          (a) To the maximum extent permitted by the DGCL, Parent will cause the
              Surviving Corporation to indemnify, defend and hold harmless each
              person who, at any time prior to the Effective Time, is an officer
              or director of Company (each, an "Executive") against all losses,
              expenses, damages, liabilities, costs, judgments and amounts paid
              in settlement of any claim, action, suit, proceeding or
              investigation based in whole or in part on such person's service
              as such and to advance amounts needed to cover the expenses
              incurred by any Executive in connection therewith in advance of
              final disposition upon the receipt of a written undertaking by the
              Executive to repay the amounts so advanced if it is ultimately
              determined that the Executive is not entitled to such
              indemnification under the DGCL. Without limiting the foregoing, in
              any case in which approval of or a determination by the Surviving
              Corporation is required to effect any indemnification, (i) the
              Executive will conclusively be deemed to have met the applicable
              standards for indemnification in connection with the transactions
              contemplated by this Agreement and (ii) Parent will cause the
              Surviving Corporation, at the election of the Executive, to direct
              that the determination of any such approval will be made by
              independent counsel selected by the Executive and reasonably
              acceptable to Parent.

          (b) If the Surviving Corporation or any of its successors or assigns
              merges, consolidates or otherwise combines with any other entity
              and is not the continuing or surviving entity, or the Surviving
              Corporation transfers all 

                                       30
<PAGE>
 
              or substantially all of its assets to any person or entity, it
              will make proper provision so that such successor assumes the
              obligations set forth in this Section 16.3.

          Company in connection with the transactions contemplated by this
          Agreement which is confidential in nature (collectively, the
          "Evaluation Material") shall be kept strictly confidential by Merger
          Subsidiary and Parent prior to the Closing Date; provided, however,
          that any Evaluation Material may be disclosed to agents, employees,
          officers, directors, investors, advisors and other representatives of
          Merger Subsidiary who need to know such Evaluation Material (it being
          agreed that such representatives shall be informed by Merger
          Subsidiary of the confidential nature of such Evaluation Material and
          shall be directed to deal with such Evaluation Material
          confidentially) and, further, may be disclosed to the extent required
          by law, including applicable securities laws, or by written or oral
          question or request for information or documents in legal proceedings,
          interrogatories, subpoenas, civil investigative demands or similar
          processes.  For purposes of this Agreement, the term "Evaluation
          Material" does not include information which (i) becomes generally
          available to the public other than as a result of disclosure by Merger
          Subsidiary or Parent or any Merger Subsidiary or Parent representative
          in violation of the terms hereof, (ii) was available on a non-
          confidential basis prior to disclosure to Merger Subsidiary or Parent
          by Company or any of their directors or any of its directors,
          officers, employees, agents or representatives, or (iii) becomes
          available to Merger Subsidiary or Parent on a nonconfidential basis
          from a source which is not bound by a confidentiality agreement with
          Company.

     17.7 PUBLIC ANNOUNCEMENTS.
          -------------------- 

          Neither Merger Subsidiary or Parent, on the one hand, nor Company or
          Shareholder, on the other hand, shall, without the approval of the
          other party (which may not be unreasonably withheld), make any press
          release or other public announcement concerning the transactions
          contemplated by this Agreement, except as and to the extent that such
          party shall be so obligated by law (including any legal obligation
          imposed on Parent in connection with its status as a publicly-held
          corporation), in which case the other party shall be advised and the
          parties 

                                       32
<PAGE>
 
          shall use their reasonable efforts to cause a mutually agreeable
          release or announcement to be issued.

     17.8  WAIVERS.
           ------- 

           Any term or provision of this Agreement may be waived, or the time
           for its performance may be extended, by the party or parties entitled
           to the benefit thereof, but any such waiver must be in writing. The
           failure of any party hereto to enforce at any time any provision of
           this Agreement shall not be construed to be a waiver of such
           provision, nor in any way to affect the validity of this Agreement or
           any part hereof or the right of any party thereafter to enforce each
           and every such provision. No waiver of any breach of this Agreement
           shall be held to constitute a waiver of any other or subsequent
           breach.

     17.9  PARTIAL INVALIDITY.
           ------------------ 

           Wherever possible, each provision hereof shall be interpreted in such
           a manner as to be effective and valid under applicable law, but in
           case any one or more of the provisions contained herein shall, for
           any reason, be held to be invalid, illegal or unenforceable in any
           respect, such invalidity, illegality or unenforceability shall not
           affect any other provisions of this Agreement, and this Agreement
           shall be construed as if such invalid, illegal or unenforceable
           provisions had never been contained herein, unless the deletion of
           such provision or provisions would result in such a material change
           as to cause the completion of the transactions contemplated hereby to
           be unreasonable.

     17.10 INCORPORATION BY REFERENCE.
           -------------------------- 

           Any and all Schedules, Exhibits, Recitals, statements, reports,
           certificates or other documents or instruments referred to herein or
           attached hereto are incorporated herein by reference thereto as
           though fully set forth at the point referred to in this Agreement.

     17.11 NO PRESUMPTION AGAINST THE DRAFTSMAN.
           ------------------------------------ 

           Each party having been represented in the negotiation of this
           Agreement, and having had ample opportunity to review the language
           hereof, there shall be no presumption against any party on the ground
           that such party was responsible for preparing this Agreement or any
           part thereof.

     17.12 FURTHER ASSURANCES.
           ------------------ 

           Each party will execute such documents and take such further actions
           after the Effective Time as may be reasonably necessary or reasonably
           requested by another party to carry out the provisions of this
           Agreement and evidence the Merger and the issuance of the Parent
           Common Stock.

     17.13 AMENDMENT.
           --------- 

           This Agreement may be amended by the parties with the approval of
           their respective boards of directors at any time before or after
           approval of this Agreement, if required, by the shareholders of the
           parties and prior to the Effective Time, but after such approval no
           amendment will be made that is adverse to such shareholders or
           otherwise materially adversely affects the rights of such
           shareholders without their further approval.

     17.14 WAIVER OF JURY TRIAL.
           -------------------- 

           EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY THAT MAY
           ARISE UNDER THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND
           SOPHISTICATED ISSUES THAT WOULD BE DIFFICULT FOR A LAYPERSON TO
           RESOLVE, AND THEREFORE IRREVOCABLY WAIVES ANY RIGHT SUCH PARTY MAY
           HAVE TO A TRIAL BY JURY IN ANY LITIGATION ARISING OUT OF OR RELATING
           TO THIS AGREEMENT OR THE MERGER. EACH PARTY MAKES THIS WAIVER
           VOLUNTARILY AND HAS CONSIDERED ITS IMPLICATIONS WITH THE ADVICE OF
           LEGAL COUNSEL. THE WAIVER OF THE RIGHT TO JURY TRIAL BY THE OTHER
           PARTIES IS A MATERIAL CONSIDERATION FOR SUCH PARTY IN ENTERING INTO
           THIS AGREEMENT.

                      ADELPHIA COMMUNICATIONS CORPORATION
                         REGISTRATION RIGHTS AGREEMENT

     THIS AGREEMENT, made as of the ______________ day of ___________________,
1998, by and among TCI DEVELOPMENT CORPORATION, a Colorado corporation ("TCI"),
and ADELPHIA COMMUNICATIONS CORPORATION, a Delaware corporation (the "Company").

     WHEREAS, TCI has acquired a number of shares of the Class A Common Stock of
the Company, par value $.01 (the "Common Stock") pursuant to that certain
Agreement and Plan of Merger by and among TCID-SVHH, Inc., SHHH Acquisition
Corp., TCI and the Company, dated August 31, 1998 (the "Merger Agreement"); and

     WHEREAS, TCI and the Company have reached the agreements set forth herein
and desire to provide that the Registrable Securities (as defined herein) shall
be held by TCI subject to the rights described herein.

     NOW, therefore, in consideration of the mutual promises and covenants
contained herein and intending to be legally bound hereby, the parties hereto
agree as follows:

     1.   Definitions.  For purposes of this Agreement:
          -----------                                  

          (a) The term "Act" means the Securities Act of 1933, as amended, or
any other statute in effect from time to time corresponding to such act.

          (b) The term "Commission" means the Securities and Exchange
Commission, or any successor agency thereto.

          (c) The terms "register," "registered," and "registration" refer to a
registration effected by preparing and filing a registration statement in
compliance with the Act and the declaration or ordering of effectiveness of such
registration statement.

          (d) The term "Registrable Securities" means (i) the shares of Common
Stock issued to TCI pursuant to the Merger Agreement and held by the Holders (as
herein defined) and (ii) any securities of the Company issued as a dividend or
other distribution with respect to, or in exchange for or in replacement of,
such Common Stock.  Registrable Securities, if transferred pursuant to an
exemption from registration under the Act, will no longer be Registrable
Securities except to the extent they shall be held by a Holder.

          (e) The term "Holder" or "Holders" means (i) TCI and (ii) any other
person or entity holding Registrable Securities to whom these registration
rights have been transferred in accordance with Section 9 of this Agreement.

     2.   Request for Registration.
          ---------------------------

          (a) If, at any time after the first anniversary of the date of this
Agreement, the Company shall receive a written request (specifying that it is
being made pursuant to this Section 2) from the Holders that the Company file a
registration statement or similar document under the Act covering Registrable
Securities held by such Holders (a "Registration Statement"), then the Company
shall promptly use its best efforts to file a Registration Statement and to
effect such registration of all Registrable Securities that Holders have
requested be so registered to be registered under the Act.  The Company shall be
obligated to effect only two registrations pursuant to this Agreement, and shall
not be obligated to effect a registration to the extent that the Holders may
sell all their Registrable Securities without being subject to a holding period
or volume limitations and without such Holders being required to deliver a
prospectus in connection therewith under the Act.

          (b) Notwithstanding the foregoing, in the event that prior to the
first anniversary of the date hereof TCI is required to dispose of Registrable
Securities in order to decrease the ownership interests attributed to TCI and
its affiliates so that TCI and its affiliates would not be deemed to have an
"attributable interest" in the Company under the horizontal attribution rules of
the Federal Communications Commission, TCI may request the Company to file a
Registration Statement  prior to the first anniversary of the date of this
Agreement without such registration counting towards  the two demand
registrations permitted pursuant to Section 2(a) above, and the Company shall
promptly use its best efforts to do so and to effect the registration of such
Registrable Securities under the Act; provided, however, that to the extent any
such request pursuant to this Section 2(b) is delivered to the Company within 45
days prior to the first anniversary of this Agreement, such request shall be
deemed to count as one of the two demand registrations granted pursuant to
Section 2(a).

          (c)  The Company shall cause Registration Statements filed in
connection with a demand under Sections 2(a) or (b) to be effective continuously
for one hundred twenty (120) days from the date of initial effectiveness of the
Registration Statement (provided that such period shall be extended by the
length of time during which TCI is blocked from selling the Registrable
Securities pursuant to Sections 2(d) and 8 of this Agreement), or until the
earliest date upon which all Registrable Securities held by Holders either (i)
have been sold by them or (ii) may be sold by them without being subject to a
holding period or volume limitations and without such Holders being required to
deliver a prospectus in connection therewith under the Act.

          (d)  Notwithstanding the foregoing, the Company may request the
Holders not to (and upon such request the Holders hereby agree not to) make any
sales pursuant to an effective Registration Statement for up to two periods of
thirty (30) days, as the Company shall specify, provided that the Company shall
furnish to each such Holder a certificate signed by the President, the Chief
Executive Officer or a Vice President of the Company stating that, in the good
faith judgment of the Company, such registration and offering would materially
interfere

                                      -2-
<PAGE>
 
with or otherwise materially adversely affect any financing, acquisition,
corporate reorganization or other material transaction or development involving
the Company or any of its affiliates or require the Company to disclose matters
that otherwise would not be required to be disclosed at such time.
 
     3.   Obligations of the Company.  Whenever required under Section 2 to use
          --------------------------                                           
its best efforts to effect the registration of any Registrable Securities, the
Company shall, as promptly as practicable:
 
          (a) Prepare and file with the Commission a Registration Statement with
respect to such Registrable Securities and use its best efforts to cause such
registration statement to become and remain effective for the applicable periods
stated under Section 2.  In connection therewith, the Company shall notify
Holders of the happening of any event during the period a Registration Statement
is effective which makes any statement made in such Registration Statement or
the related prospectus untrue in any material respect or which requires the
making of any changes in such Registration Statement or prospectus so that, as
of such date, the statements therein are not misleading and do not omit to state
a material fact required to be stated therein or necessary to make the
statements therein not misleading (which advice shall be accompanied by an
instruction to suspend the use of the prospectus until the requisite changes
have been made) and consistent with the Company's past practices, prepare a
supplement or post-effective amendment to a Registration Statement or the
related prospectus or any document incorporated therein by reference or file any
other required document so that, as thereafter delivered to the purchasers of
the Registrable Securities, such prospectus will not contain any untrue
statement of a material fact or omit to state a material fact required to be
stated therein or necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading;

          (b) Prepare and file with the Commission such amendments and
supplements to such Registration Statement and the prospectus used in connection
with such Registration Statement as may be necessary to keep the prospectus
current and comply with the provisions of the Act with respect to the
disposition of all securities covered by such registration statement;

          (c) Notify the Holders, (i) when the Registration Statement becomes
effective, (ii) when the filing of a post-effective amendment to the
Registration Statement or supplement to the prospectus is required, when the
same is filed and, in the case of a post-effective amendment, when the same
becomes effective, (iii) of any request by the Commission for any amendment of
or supplement to the Registration Statement or any prospectus relating thereto
or for additional information, and (iv) of the entry of any stop order
suspending the effectiveness of the Registration Statement or of the initiation
of any proceedings for that purpose;

          (d) Furnish to the Holders and deliver as directed by them a conformed
copy of the Registration Statement as declared effective by the Commission and
of each post-effective amendment thereto, such numbers of copies of a
prospectus, including a preliminary prospectus or supplement, in conformity with
the requirements of the Act, and such other documents as they

                                      -3-
<PAGE>
 
may reasonably request in order to facilitate the disposition of Registrable
Securities owned by them;

          (e) Register and qualify the securities covered by the Registration
Statement under such other securities or Blue Sky laws of such jurisdictions as
shall be reasonably requested by the Holders, provided that the Company shall
not be required in connection therewith or as a condition thereto to qualify to
do business or to file a general consent to service of process in any such
states or jurisdictions; and

          (f) Cause such Registrable Securities covered by the Registration
Statement to be listed on the principal exchange or exchanges or qualified for
trading on the principal over-the-counter market on which the Registrable
Securities are then listed or traded upon the sale of such Registrable
Securities pursuant to the Registration Statement.

     4.   Furnish Information.  It shall be a condition precedent to the
          -------------------                                           
obligations of the Company to take any action pursuant to this Agreement that
the Holders shall furnish to the Company such information regarding them, the
Registrable Securities held by them, and the intended method of disposition of
such securities as the Company shall reasonably request and as shall be required
in connection with the action to be taken by the Company.  In addition, the
Holders agree to promptly provide the Company written notice of sales of
Registrable Securities (including share amounts) upon request by the Company in
writing.

     5.   Expenses of Registration.  All expenses incurred in connection with a
          ------------------------                                             
Registration Statement pursuant to Section 2 (excluding underwriters' discounts
and commissions), including without limitation all registration and
qualification fees, printers' and accounting fees, fees and disbursements of
counsel for the Company, but not including fees and disbursements of counsel,
consultants or other advisors for the selling Holders, shall be borne by the
Company.

     6.   Indemnification and Contribution.  In the event any Registrable
          --------------------------------                               
Securities are included in a registration statement under this Agreement:
 
          (a) To the extent not prohibited by law the Company will indemnify and
hold harmless each Holder requesting or joining in a registration, any
underwriter (as defined in the Act) for it, and each person or entity, if any,
who controls such Holder or underwriter within the meaning of the Act or the
Securities Exchange Act of 1934 (the "1934 Act") against any losses, claims,
damages or liabilities, joint or several, to which they may become subject under
the Act, the 1934 Act or otherwise, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based on any
untrue or alleged untrue statement of any material fact contained in such
Registration Statement, including any preliminary prospectus or final
prospectus, or any amendments or supplements thereto, or arise out of or are
based upon the omission or alleged omission to state therein a material fact
required to be stated therein, or necessary to make the statements therein not
misleading or arise out of any violation by the Company of any rule or
regulation promulgated under the Act or the 1934 Act applicable to the Company
and relating to action or inaction required of the Company in connection with
any such registration; and will reimburse each such Holder, such underwriter, or
such controlling person for any legal or other expenses reasonably incurred by
them in connection with investigating or 

                                      -4-
<PAGE>
 
defending any such loss, claim, damage, liability or action; provided, however,
that the indemnity agreement contained in this Section 7(a) shall not apply to
amounts paid in settlement of any such loss, claim, damage, liability or action
to the extent that it arises out of or is based upon an untrue statement or
alleged untrue statement or omission or alleged omission made in connection with
such Registration Statement, preliminary prospectus, final prospectus, or
amendments or supplements thereto, in reliance upon and in conformity with
written information furnished expressly for use in connection with such
registration by any such Holder, underwriter or controlling person.

          (b) To the extent not prohibited by law, each Holder requesting or
joining in a registration will severally and not jointly indemnify and hold
harmless the Company, each of its directors, each of its officers who have
signed the Registration Statement, and each person, if any, who controls the
Company (within the meaning of the Act or the 1934 Act) against any losses,
claims, damages or liabilities, joint or several, to which the Company or any
such director, officer, controlling person, agent or underwriter may become
subject, under the Act or otherwise, insofar as such losses, claims, damages or
liabilities (or actions in respect thereto) arise out of or are based upon any
untrue statement or alleged untrue statement of any material fact contained in
such Registration Statement, including any preliminary prospectus or final
prospectus, or any amendments or supplements thereto, or arise out of or are
based upon the omission or alleged omission to state therein a material fact
required to be stated therein or necessary to make the statements therein not
misleading, in each case to the extent, but only to the extent, that such untrue
statement or alleged untrue statement or omission or alleged omission was made
in such registration statement, preliminary or final prospectus, or amendments
or supplements thereto, in reliance upon and in conformity with written
information furnished by such Holder expressly for use in connection with such
registration; and each such Holder will reimburse any legal or other expenses
reasonably incurred by the Company or any such director, officer, controlling
person, agent or underwriter in connection with investigating or defending any
such loss, claim, damage, liability or action; provided, however, that the
indemnity agreement contained in this Section 7(b) shall not apply to amounts
paid in settlement of any such loss, claim, damage, liability or action if such
settlement is affected without the consent of such Holder (which consent shall
not be unreasonably withheld).
 
          (c) Promptly after receipt by an indemnified party under this Section
of notice of the commencement of any action, such indemnified party will, if a
claim in respect thereof is to be made against any indemnifying party under this
Section, notify the indemnifying party in writing of the commencement thereof
and (unless the interest of the indemnifying party conflicts with that of the
indemnified party) the indemnifying party shall have the right to participate at
its own expense in, and, to the extent the indemnifying party so desires,
jointly with any other indemnifying party similarly noticed, to assume the
defense thereof with counsel mutually satisfactory to the parties.  The omission
so to notify the indemnifying party as provided herein will not relieve the
indemnifying party of any liability that he may have to any indemnified party
under this Section, except to the extent such failure to notify an indemnifying
party actually prejudices his ability to defend such action.
 
                                      -5-
<PAGE>
 
          (d) In order to provide for just and equitable contribution to joint
liability under the Act in any case in which either (i) any party entitled to
indemnification under this Agreement makes a claim for indemnification pursuant
to this Section 7 but it is judicially determined (by the entry of a final
judgment or decree by a court of competent jurisdiction and the expiration of
time to appeal or the denial of the last right of appeal) that such
indemnification cannot be enforced in such case notwithstanding the fact that
this Section 7 provides for indemnification in such case, or (ii) contribution
under the Act may be required on the part of any party in circumstances for
which indemnification is provided under this Section 7; then, and in each such
case, the indemnifying party, in lieu of indemnifying such indemnified party
hereunder, shall contribute to the amount paid or payable by such indemnified
party as a result of such loss, liability, claim, damage, or expense in such
proportion as is appropriate to reflect the relative fault of the indemnifying
party on the one hand and the indemnified party on the other in connection with
statements or omissions that resulted in such loss, liability, claim, damage or
expense as well as any other relevant equitable considerations.  The relative
fault of the indemnifying party and of the indemnified party shall be determined
by reference to, among other things, whether the untrue or alleged untrue
statement of a material fact or the omission or alleged omission to state a
material fact relates to information supplied (or omitted to be supplied) by the
indemnifying party or the indemnified party and the parties' relative intent,
knowledge, access to information, and opportunity to correct or prevent such
statement or omission; provided, however, that, in any such case, (A) no such
Holder will be required to contribute any amount in excess of the net proceeds
of all such Registrable Securities sold by it pursuant to such registration
statement; and (B) no person or entity guilty of fraudulent misrepresentation
(within the meaning of Section 11(f) of the Act) will be entitled to
contribution from any person or entity who was not guilty of such fraudulent
misrepresentation.

     7.   Reports Under Securities Exchange Act of 1934.  The Company agrees to
          ---------------------------------------------                        
use its best efforts to make and keep public information available, as those
terms are understood and defined in Rule 144, at all times from the date on
which sales may first be made by the Holders under Rule 144 so long as the
Holders shall hold Registrable Securities.

     8.   Lockup Agreement.   In consideration for the Company agreeing to its
          ----------------                                                    
obligations under this Agreement, in the event that each of the directors and
executive officers of the Company, John J. Rigas and the members of the
immediate family of John J. Rigas execute an agreement not to sell, make any
short sale of, loan, grant any option for the purchase of or otherwise dispose
of any Common Stock of the Company of which they are the beneficial owners
(other than (a) those included in the registration and (b) sale transactions not
involving a public offering, provided that the transferee of such person as a
condition thereto and in connection therewith, agrees to be bound by such
restriction), without the prior written consent of the Company or such
underwriters, as the case may be, for such period of time not to exceed 120 days
from the effective date of such registration as the Company or the underwriters
may specify, each Holder shall agree in connection with any registration of the
Company's securities for sale by the Company to the general public, upon the
request of the Company or the underwriters managing any underwritten offering of
the Company's securities, on the same terms not to sell, make any short sale of,
loan, grant any option for the purchase of, or otherwise dispose of any
Registrable Securities (other than (a) those included in the registration and
(b) sale

                                      -6-
<PAGE>
 
transactions not involving a public offering, provided that the transferee of
such Holder as a condition thereto and in connection therewith, agrees to be
bound by and joins into this Section 8), without the prior written consent of
the Company or such underwriters, as the case may be, for such period of time
not to exceed 120 days from the effective date of such registration as the
Company or the underwriters may specify; provided, however, that such
restrictions on sales by Holders shall not apply if a request for registration
has been made by Holders prior to the receipt of a notice from the Company or
its underwriters under this Section 8.  During any period that sales of
Registrable Securities by the Holder are restricted under this Section, at the
Holder's request, the Company will give written notice to the Holder as soon as
the restrictions on sale terminate.  The Company hereby agrees to give Holder
among other things written notice of the filing of a registration statement for
a proposed underwritten offering to which the restrictions in this Section 8
could apply if so requested.

     9.   Transfer of Registration Rights.  The registration rights of the
          -------------------------------                                 
Holders under Section 2 may be not transferred except to a wholly-owned
subsidiary of Tele-Communications, Inc. ("TCI Parent") or any successor to TCI
Parent by merger, consolidation or otherwise, provided that any such transferee
agrees in writing to be bound by the terms of and joins in this Agreement as a
Holder in all respects hereunder.  The Company shall be given written notice by
the Holder at the time of such transfer stating the name and address of the
transferee and identifying the securities with respect to which the rights under
this Agreement are being assigned.  This Agreement shall inure to the benefit of
and be binding on the successors and assigns of the Company, and of the Holders
hereto which successors and assigns are permitted to become Holders under this
Section 9.
 
     10.  No Piggyback Registrations. The Company hereby covenants and agrees
          --------------------------
with TCI that it will not permit any holder or prospective holder of its
securities to register such securities on any Registration Statement filed
pursuant to this Agreement.

     11.  Entire Agreement.  This Agreement and the documents referred to herein
          -----------------

matter hereof and supersedes all prior agreements and negotiations relating
thereto.

     12.  Governing Law.  This Agreement, together with the rights and
          -------------                                               
obligations of the parties hereunder shall be governed by and construed and
enforced in accordance with the laws of the State of Delaware without regard to
any jurisdiction's conflicts of laws provisions.

     13.  Counterparts.  This Agreement may be executed in two or more

                      ADELPHIA COMMUNICATIONS CORPORATION
                         REGISTRATION RIGHTS AGREEMENT

          THIS AGREEMENT, made as of the 30th day of September, 1998, by and
among TCI DEVELOPMENT CORPORATION, a Colorado corporation ("TCI"), and ADELPHIA
COMMUNICATIONS CORPORATION, a Delaware corporation (the "Company").

          WHEREAS, TCI has acquired a number of shares of the Class A Common
Stock of the Company, par value $.01 (the "Common Stock") pursuant to that
certain Agreement and Plan of Merger by and among TCID-SVHH, Inc., SHHH
Acquisition Corp., TCI and the Company, dated August 31, 1998 (the "Merger
Agreement"); and

          WHEREAS, TCI and the Company have reached the agreements set forth
herein and desire to provide that the Registrable Securities (as defined herein)
shall be held by TCI subject to the rights described herein.

          NOW, therefore, in consideration of the mutual promises and covenants
contained herein and intending to be legally bound hereby, the parties hereto
agree as follows:

          1.  Definitions.  For purposes of this Agreement:
              -----------                                  

               (a) The term "Act" means the Securities Act of 1933, as amended,
or any other statute in effect from time to time corresponding to such act.

               (b) The term "Commission" means the Securities and Exchange
Commission, or any successor agency thereto.

               (c) The terms "register," "registered," and "registration" refer
to a registration effected by preparing and filing a registration statement in
compliance with the Act and the declaration or ordering of effectiveness of such
registration statement.

               (d) The term "Registrable Securities" means (i) the shares of
Common Stock issued to TCI pursuant to the Merger Agreement and held by the
Holders (as herein defined) and (ii) any securities of the Company issued as a
dividend or other distribution with respect to, or in exchange for or in
replacement of, such Common Stock. Registrable Securities, if transferred
pursuant to an exemption from registration under the Act, will no longer be
Registrable Securities except to the extent they shall be held by a Holder.

               (e) The term "Holder" or "Holders" means (i) TCI and (ii) any
other person or entity holding Registrable Securities to whom these registration
rights have been transferred in accordance with Section 9 of this Agreement.
<PAGE>
 
     2.   Request for Registration.
          ---------------------------

          (a) If, at any time after the first anniversary of the date of this
Agreement, the Company shall receive a written request (specifying that it is
being made pursuant to this Section 2) from the Holders that the Company file a
registration statement or similar document under the Act covering Registrable
Securities held by such Holders (a "Registration Statement"), then the Company
shall promptly use its best efforts to file a Registration Statement and to
effect such registration of all Registrable Securities that Holders have
requested be so registered to be registered under the Act.  The Company shall be
obligated to effect only two registrations pursuant to this Agreement, and shall
not be obligated to effect a registration to the extent that the Holders may
sell all their Registrable Securities without being subject to a holding period
or volume limitations and without such Holders being required to deliver a
prospectus in connection therewith under the Act.

          (b) Notwithstanding the foregoing, in the event that prior to the
first anniversary of the date hereof TCI is required to dispose of Registrable
Securities in order to decrease the ownership interests attributed to TCI and
its affiliates so that TCI and its affiliates would not be deemed to have an
"attributable interest" in the Company under the horizontal attribution rules of
the Federal Communications Commission, TCI may request the Company to file a
Registration Statement  prior to the first anniversary of the date of this
Agreement without such registration counting towards  the two demand
registrations permitted pursuant to Section 2(a) above, and the Company shall
promptly use its best efforts to do so and to effect the registration of such
Registrable Securities under the Act; provided, however, that to the extent any
such request pursuant to this Section 2(b) is delivered to the Company within 45
days prior to the first anniversary of this Agreement, such request shall be
deemed to count as one of the two demand registrations granted pursuant to
Section 2(a).

          (c)  The Company shall cause Registration Statements filed in
connection with a demand under Sections 2(a) or (b) to be effective continuously
for one hundred twenty (120) days from the date of initial effectiveness of the
Registration Statement (provided that such period shall be extended by the
length of time during which TCI is blocked from selling the Registrable
Securities pursuant to Sections 2(d) and 8 of this Agreement), or until the
earliest date upon which all Registrable Securities held by Holders either (i)
have been sold by them or (ii) may be sold by them without being subject to a
holding period or volume limitations and without such Holders being required to
deliver a prospectus in connection therewith under the Act.

          (d)  Notwithstanding the foregoing, the Company may request the
Holders not to (and upon such request the Holders hereby agree not to) make any
sales pursuant to an effective Registration Statement for up to two periods of
thirty (30) days, as the Company shall specify, provided that the Company shall
furnish to each such Holder a certificate signed by the President, the Chief
Executive Officer or a Vice President of the Company stating that, in the good
faith judgment of the Company, such registration and offering would materially
interfere

                                      -2-
<PAGE>
 
with or otherwise materially adversely affect any financing, acquisition,
corporate reorganization or other material transaction or development involving
the Company or any of its affiliates or require the Company to disclose matters
that otherwise would not be required to be disclosed at such time.
 
     3.   Obligations of the Company.  Whenever required under Section 2 to use
          --------------------------                                           
its best efforts to effect the registration of any Registrable Securities, the
Company shall, as promptly as practicable:
 
          (a) Prepare and file with the Commission a Registration Statement with
respect to such Registrable Securities and use its best efforts to cause such
registration statement to become and remain effective for the applicable periods
stated under Section 2.  In connection therewith, the Company shall notify
Holders of the happening of any event during the period a Registration Statement
is effective which makes any statement made in such Registration Statement or
the related prospectus untrue in any material respect or which requires the
making of any changes in such Registration Statement or prospectus so that, as
of such date, the statements therein are not misleading and do not omit to state
a material fact required to be stated therein or necessary to make the
statements therein not misleading (which advice shall be accompanied by an
instruction to suspend the use of the prospectus until the requisite changes
have been made) and consistent with the Company's past practices, prepare a
supplement or post-effective amendment to a Registration Statement or the
related prospectus or any document incorporated therein by reference or file any
other required document so that, as thereafter delivered to the purchasers of
the Registrable Securities, such prospectus will not contain any untrue
statement of a material fact or omit to state a material fact required to be
stated therein or necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading;

          (b) Prepare and file with the Commission such amendments and
supplements to such Registration Statement and the prospectus used in connection
with such Registration Statement as may be necessary to keep the prospectus
current and comply with the provisions of the Act with respect to the
disposition of all securities covered by such registration statement;

          (c) Notify the Holders, (i) when the Registration Statement becomes
effective, (ii) when the filing of a post-effective amendment to the
Registration Statement or supplement to the prospectus is required, when the
same is filed and, in the case of a post-effective amendment, when the same
becomes effective, (iii) of any request by the Commission for any amendment of
or supplement to the Registration Statement or any prospectus relating thereto
or for additional information, and (iv) of the entry of any stop order
suspending the effectiveness of the Registration Statement or of the initiation
of any proceedings for that purpose;

          (d) Furnish to the Holders and deliver as directed by them a conformed
copy of the Registration Statement as declared effective by the Commission and
of each post-effective amendment thereto, such numbers of copies of a
prospectus, including a preliminary prospectus or supplement, in conformity with
the requirements of the Act, and such other documents as they

                                      -3-
<PAGE>
 
may reasonably request in order to facilitate the disposition of Registrable
Securities owned by them;

          (e) Register and qualify the securities covered by the Registration
Statement under such other securities or Blue Sky laws of such jurisdictions as
shall be reasonably requested by the Holders, provided that the Company shall
not be required in connection therewith or as a condition thereto to qualify to
do business or to file a general consent to service of process in any such
states or jurisdictions; and

          (f) Cause such Registrable Securities covered by the Registration
Statement to be listed on the principal exchange or exchanges or qualified for
trading on the principal over-the-counter market on which the Registrable
Securities are then listed or traded upon the sale of such Registrable
Securities pursuant to the Registration Statement.

     4.   Furnish Information.  It shall be a condition precedent to the
          -------------------                                           
obligations of the Company to take any action pursuant to this Agreement that
the Holders shall furnish to the Company such information regarding them, the
Registrable Securities held by them, and the intended method of disposition of
such securities as the Company shall reasonably request and as shall be required
in connection with the action to be taken by the Company.  In addition, the
Holders agree to promptly provide the Company written notice of sales of
Registrable Securities (including share amounts) upon request by the Company in
writing.

     5.   Expenses of Registration.  All expenses incurred in connection with a
          ------------------------                                             
Registration Statement pursuant to Section 2 (excluding underwriters' discounts
and commissions), including without limitation all registration and
qualification fees, printers' and accounting fees, fees and disbursements of
counsel for the Company, but not including fees and disbursements of counsel,
consultants or other advisors for the selling Holders, shall be borne by the
Company.

     6.   Indemnification and Contribution.  In the event any Registrable
          --------------------------------                               
Securities are included in a registration statement under this Agreement:
 
          (a) To the extent not prohibited by law the Company will indemnify and
hold harmless each Holder requesting or joining in a registration, any
underwriter (as defined in the Act) for it, and each person or entity, if any,
who controls such Holder or underwriter within the meaning of the Act or the
Securities Exchange Act of 1934 (the "1934 Act") against any losses, claims,
damages or liabilities, joint or several, to which they may become subject under
the Act, the 1934 Act or otherwise, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based on any
untrue or alleged untrue statement of any material fact contained in such
Registration Statement, including any preliminary prospectus or final
prospectus, or any amendments or supplements thereto, or arise out of or are
based upon the omission or alleged omission to state therein a material fact
required to be stated therein, or necessary to make the statements therein not
misleading or arise out of any violation by the Company of any rule or
regulation promulgated under the Act or the 1934 Act applicable to the Company
and relating to action or inaction required of the Company in connection with
any such registration; and will reimburse each such Holder, such underwriter, or
such controlling person for any legal or other expenses reasonably incurred by
them in connection with investigating or 

                                      -4-
<PAGE>
 
defending any such loss, claim, damage, liability or action; provided, however,
that the indemnity agreement contained in this Section 7(a) shall not apply to
amounts paid in settlement of any such loss, claim, damage, liability or action
to the extent that it arises out of or is based upon an untrue statement or
alleged untrue statement or omission or alleged omission made in connection with
such Registration Statement, preliminary prospectus, final prospectus, or
amendments or supplements thereto, in reliance upon and in conformity with
written information furnished expressly for use in connection with such
registration by any such Holder, underwriter or controlling person.

          (b) To the extent not prohibited by law, each Holder requesting or
joining in a registration will severally and not jointly indemnify and hold
harmless the Company, each of its directors, each of its officers who have
signed the Registration Statement, and each person, if any, who controls the
Company (within the meaning of the Act or the 1934 Act) against any losses,
claims, damages or liabilities, joint or several, to which the Company or any
such director, officer, controlling person, agent or underwriter may become
subject, under the Act or otherwise, insofar as such losses, claims, damages or
liabilities (or actions in respect thereto) arise out of or are based upon any
untrue statement or alleged untrue statement of any material fact contained in
such Registration Statement, including any preliminary prospectus or final
prospectus, or any amendments or supplements thereto, or arise out of or are
based upon the omission or alleged omission to state therein a material fact
required to be stated therein or necessary to make the statements therein not
misleading, in each case to the extent, but only to the extent, that such untrue
statement or alleged untrue statement or omission or alleged omission was made
in such registration statement, preliminary or final prospectus, or amendments
or supplements thereto, in reliance upon and in conformity with written
information furnished by such Holder expressly for use in connection with such
registration; and each such Holder will reimburse any legal or other expenses
reasonably incurred by the Company or any such director, officer, controlling
person, agent or underwriter in connection with investigating or defending any
such loss, claim, damage, liability or action; provided, however, that the
indemnity agreement contained in this Section 7(b) shall not apply to amounts
paid in settlement of any such loss, claim, damage, liability or action if such
settlement is affected without the consent of such Holder (which consent shall
not be unreasonably withheld).
 
          (c) Promptly after receipt by an indemnified party under this Section
of notice of the commencement of any action, such indemnified party will, if a
claim in respect thereof is to be made against any indemnifying party under this
Section, notify the indemnifying party in writing of the commencement thereof
and (unless the interest of the indemnifying party conflicts with that of the
indemnified party) the indemnifying party shall have the right to participate at
its own expense in, and, to the extent the indemnifying party so desires,
jointly with any other indemnifying party similarly noticed, to assume the
defense thereof with counsel mutually satisfactory to the parties.  The omission
so to notify the indemnifying party as provided herein will not relieve the
indemnifying party of any liability that he may have to any indemnified party
under this Section, except to the extent such failure to notify an indemnifying
party actually prejudices his ability to defend such action.

          (d) In order to provide for just and equitable contribution to joint
liability under the Act in any case in which either (i) any party entitled to
indemnification under this Agreement makes a claim for indemnification pursuant
to this Section 7 but it is judicially determined (by the entry of a final
judgment or decree by a court of competent jurisdiction and the expiration of
time to appeal or the denial of the last right of appeal) that such
indemnification cannot be enforced in such case notwithstanding the fact that
this Section 7 provides for indemnification in such case, or (ii) contribution
under the Act may be required on the part of any party in circumstances for
which indemnification is provided under this Section 7; then, and in each such
case, the indemnifying party, in lieu of indemnifying such indemnified party
hereunder, shall contribute to the amount paid or payable by such indemnified
party as a result of such loss, liability, claim, damage, or expense in such
proportion as is appropriate to reflect the relative fault of the indemnifying
party on the one hand and the indemnified party on the other in connection with
statements or omissions that resulted in such loss, liability, claim, damage or
expense as well as any other relevant equitable considerations.  The relative
fault of the indemnifying party and of the indemnified party shall be determined
by reference to, among other things, whether the untrue or alleged untrue
statement of a material fact or the omission or alleged omission to state a
material fact relates to information supplied (or omitted to be supplied) by the
indemnifying party or the indemnified party and the parties' relative intent,
knowledge, access to information, and opportunity to correct or prevent such
statement or omission; provided, however, that, in any such case, (A) no such
Holder will be required to contribute any amount in excess of the net proceeds
of all such Registrable Securities sold by it pursuant to such registration
statement; and (B) no person or entity guilty of fraudulent misrepresentation
(within the meaning of Section 11(f) of the Act) will be entitled to
contribution from any person or entity who was not guilty of such fraudulent
misrepresentation.

     7.   Reports Under Securities Exchange Act of 1934.  The Company agrees to
          ---------------------------------------------                        
use its best efforts to make and keep public information available, as those
terms are understood and defined in Rule 144, at all times from the date on
which sales may first be made by the Holders under Rule 144 so long as the
Holders shall hold Registrable Securities.

     8.   Lockup Agreement.   In consideration for the Company agreeing to its
          ----------------                                                    
obligations under this Agreement, in the event that each of the directors and
executive officers of the Company, John J. Rigas and the members of the
immediate family of John J. Rigas execute an agreement not to sell, make any
short sale of, loan, grant any option for the purchase of or otherwise dispose
of any Common Stock of the Company of which they are the beneficial owners
(other than (a) those included in the registration and (b) sale transactions not
involving a public offering, provided that the transferee of such person as a
condition thereto and in connection therewith, agrees to be bound by such
restriction), without the prior written consent of the Company or such
underwriters, as the case may be, for such period of time not to exceed 120 days
from the effective date of such registration as the Company or the underwriters
may specify, each Holder shall agree in connection with any registration of the
Company's securities for sale by the Company to the general public, upon the
request of the Company or the underwriters managing any underwritten offering of
the Company's securities, on the same terms not to sell, make any short sale of,
loan, grant any option for the purchase of, or otherwise dispose of any
Registrable Securities (other than (a) those included in the registration and
(b) sale

                                      -6-

transactions not involving a public offering, provided that the transferee of
such Holder as a condition thereto and in connection therewith, agrees to be
bound by and joins into this Section 8), without the prior written consent of
the Company or such underwriters, as the case may be, for such period of time
not to exceed 120 days from the effective date of such registration as the
Company or the underwriters may specify; provided, however, that such
restrictions on sales by Holders shall not apply if a request for registration
has been made by Holders prior to the receipt of a notice from the Company or
its underwriters under this Section 8.  During any period that sales of
Registrable Securities by the Holder are restricted under this Section, at the
Holder's request, the Company will give written notice to the Holder as soon as
the restrictions on sale terminate.  The Company hereby agrees to give Holder
among other things written notice of the filing of a registration statement for
a proposed underwritten offering to which the restrictions in this Section 8
could apply if so requested.

     9.   Transfer of Registration Rights.  The registration rights of the
          -------------------------------                                 
Holders under Section 2 may be not transferred except to a wholly-owned
subsidiary of Tele-Communications, Inc. ("TCI Parent") or any successor to TCI
Parent by merger, consolidation or otherwise, provided that any such transferee
agrees in writing to be bound by the terms of and joins in this Agreement as a
Holder in all respects hereunder.  The Company shall be given written notice by
the Holder at the time of such transfer stating the name and address of the
transferee and identifying the securities with respect to which the rights under
this Agreement are being assigned.  This Agreement shall inure to the benefit of
and be binding on the successors and assigns of the Company, and of the Holders
hereto which successors and assigns are permitted to become Holders under this
Section 9.
 
     10.  No Piggyback Registrations. The Company hereby covenants and agrees
          --------------------------
with TCI that it will not permit any holder or prospective holder of its
securities to register such securities on any Registration Statement filed
pursuant to this Agreement.

     11.  Entire Agreement.  This Agreement and the documents referred to herein
          -----------------                                                     
constitute the entire agreement among the parties with respect to the subject
matter hereof and supersedes all prior agreements and negotiations relating
thereto.

     12.  Governing Law.  This Agreement, together with the rights and
          -------------                                               
obligations of the parties hereunder shall be governed by and construed and
enforced in accordance with the laws of the State of Delaware without regard to
any jurisdiction's conflicts of laws provisions.

     13.  Counterparts.  This Agreement may be executed in two or more
          ------------

together shall constitute one and the same instrument.
