Adelphia Communications Corporation

Attn: Brad Sonnenberg

Ladies and Gentlemen:

      Reference is made to the Asset Purchase Agreement between Time Warner NY
Cable LLC, a Delaware limited liability company ("TWNY"), and Adelphia
Communications Corporation, a Delaware corporation ("Adelphia"), dated as of
April 20, 2005, as amended on the date hereof (the "TW Purchase Agreement").
Capitalized terms used but not otherwise defined herein shall have the
respective meanings ascribed to them in the TW Purchase Agreement.

      1. Timing of Effectiveness of the Plan and the Closing. The parties hereto
agree that the condition set forth in Section 6.1(a) of the TW Purchase
Agreement with respect to the effectiveness of the Plan, shall be satisfied by
the Plan becoming effective contemporaneously with the Closing.

      2. Assumption of Effectiveness. In determining whether Sections 6.1(f),
6.2(a), 6.2(b) (except for covenants to the extent related to Adelphia's
obligations to use commercially reasonable efforts to fulfill the conditions
precedent to its obligations under the TW Purchase Agreement), 6.2(d) (to the
extent relating to 6.2(a) and 6.2(b) (except for covenants to the extent related
to Adelphia's obligations to use commercially reasonable efforts to fulfill the
conditions precedent to its obligations under the TW Purchase Agreement)) and
6.2(e) of the TW Purchase Agreement have been satisfied, the parties hereto
shall assume that the Plan is effective in accordance with its terms and shall
assume that any other plan of reorganization relating to any Managed Cable
Entity or any other Transferred Asset as to which the only condition to its
effectiveness that has not been satisfied or waived is the Closing is effective
in accordance with its terms.

      3. Consent to Plan and Disclosure Statement. TWNY hereby acknowledges that
the Plan, all exhibits attached thereto, the Disclosure Statement (except for
the sections of the Disclosure Statement describing the Plan to the extent such
description is inconsistent with the Plan; it being understood that

<PAGE>

TWNY shall promptly following the date hereof inform Adelphia of any such
inconsistency it identifies) and the Disclosure Statement Motion (each of which
is attached hereto) are acceptable in form and substance to TWNY and otherwise
satisfy the requirements of the fourth sentence of Section 5.13(a) of the TW
Purchase Agreement to the extent relating to the Plan, the exhibits attached
thereto, the Disclosure Statement (except for the sections of the Disclosure
Statement describing the Plan to the extent such description is inconsistent
with the Plan) and the Disclosure Statement Motion. TWNY consents to the filing
of such documents with the Bankruptcy Court. Adelphia hereby agrees to waive the
conditions set forth in Sections 13.01(f), 13.01(g) and 13.02(b) of the Plan in
order to effect the confirmation or effectiveness, as applicable, of the Plan,
if so requested by TWNY, if the failure to so waive such condition(s) would
reasonably be expected to materially delay or impair the Transaction. Adelphia
hereby acknowledges and agrees that with respect to the conditions set forth in
Sections 13.01(a), 13.01(b) and 13.01(c) of the Plan, if so requested by TWNY,
it will exercise its discretion in a reasonable manner. The foregoing shall not
prejudice either party's position with respect to Adelphia's waiver obligations,
if any, in respect of any provision of Sections 13.01 and 13.02 of the Plan that
is not addressed in this paragraph.

      4. Reservation of Rights. It is understood and agreed that the filing of
the Plan and TWNY's consent thereto are without prejudice to Adelphia's rights
to amend the Plan and TWNY's right to consent or to withhold consent to any
amendment (and the absence or presence of any provision of the Plan as filed
shall not be taken into account in determining such rights of Adelphia or TWNY),
in each case, in accordance with applicable provisions of the TW Purchase
Agreement.

      5. Issuance of Parent Capital Stock. TWNY acknowledges that in connection
with the Transaction it currently intends to cause Parent to effect a stock
dividend and distribute approximately 999,999 shares of Parent Capital Stock in
respect of each share of Parent Capital Stock outstanding as of the record date
for such dividend. TWNY further acknowledges and agrees that in the event that
the number of shares of Parent Capital Stock to be issued at the Closing is
changed it shall use its commercially reasonable efforts to cause the initial
pricing of such shares to be in a reasonable range in light of the current
intended share price and then prevailing market conditions.

         This letter agreement may be executed in one or more counterparts, each
of which shall be deemed an original, and all of which shall constitute one and
the same letter agreement.

         This letter agreement shall be governed by and construed in accordance
with the TW Purchase Agreement.

               AMENDMENT NO. 1 TO ASSET PURCHASE AGREEMENT BETWEEN
                     ADELPHIA COMMUNICATIONS CORPORATION AND
                            TIME WARNER NY CABLE LLC

      This Amendment, dated June 24, 2005 (this "Amendment"), amends the Asset
Purchase Agreement, between Adelphia Communications Corporation ("Seller") and
Time Warner NY Cable LLC ("Buyer"), dated as of April 20, 2005 (the "TW Purchase
Agreement"). Capitalized terms used but not otherwise defined herein shall have
the respective meanings ascribed to them in the TW Purchase Agreement.

      WHEREAS, the parties hereto desire to amend the TW Purchase Agreement
pursuant to Section 9.2 thereof to clarify certain provisions contained therein.

      NOW, THEREFORE, in consideration of the foregoing, the parties hereto,
intending to be legally bound, hereby agree as follows:

      1. Section 9.5 of the TW Purchase Agreement shall be amended by inserting
immediately following the phrase "cause each and every Debtor, including each
that is an Asset Transferring Subsidiary hereunder," the phrase, "but in each
case excluding any Debtor that is a Transferred Joint Venture Entity (as such
term is defined in the Friendco Purchase Agreement)", and adding at the end of
such Section the sentence, "Nothing in this Section 9.5 is intended to supersede
the provisions of paragraphs 4 and 5 of the Bankruptcy Court's order of April
21, 2005 entitled `Supplemental Order.'"

      2. Section 5.13(b) of the TW Purchase Agreement shall be amended by: (a)
deleting the phrase: "70 days" in the first sentence of such Section and
substituting for it the phrase: "80 days"; (b) deleting the word: "seventieth"
in each place it appears in the first sentence of such Section and substituting
for it, in each case, the word: "eightieth"; (c) deleting the phrase: "40 days"
in the second sentence of such Section and substituting for it the phrase: "50
days"; and (d) deleting the phrase: "20 days" in the third sentence of such
Section and substituting for it the phrase, "30 days".

      3. Section 5.13(c) of the TW Purchase Agreement shall be amended by
deleting the phrase: "70 days" in the first sentence of such Section and
substituting for it the phrase: "80 days".

      4. Section 5.13(d) of the TW Purchase Agreement shall be amended by: (a)
deleting the phrase: "70 days" in the second sentence of such Section and

<PAGE>

substituting for it the phrase: "80 days" and (b) deleting the word:
"seventieth" in the second sentence of such Section and substituting for it the
word: "eightieth".

      Except as specifically amended by this Amendment, the TW Purchase
Agreement will remain in full force and effect and is hereby ratified and
confirmed. This Amendment shall be construed as one with the TW Purchase
Agreement, and the TW Purchase Agreement shall, where the context requires, be
read and construed so as to incorporate this Amendment.

      This Amendment may be executed in one or more counterparts, each of which
shall be deemed an original, and all of which shall constitute one and the same
Amendment.

      This Amendment shall be governed by and construed in accordance with the
TW Purchase Agreement.

<PAGE>

      IN WITNESS WHEREOF, the parties have executed or caused this Amendment to
be executed as of the date first written above.
