Item 1.01. Entry into a Material Definitive Agreement.

On February 25, 2005, Adelphia Communications Corporation (the "Company") and certain of its subsidiaries, including the registrants, entered into and closed on the Third Amended and Restated Credit and Guaranty Agreement, by and among UCA LLC, Century Cable Holdings, LLC, Century-TCI California, L.P., Olympus Cable Holdings, LLC, Parnassos, L.P., FrontierVision Operating Partners, L.P., ACC Investment Holdings, Inc., Arahova Communications, Inc., Adelphia California Cablevision, LLC, as borrowers, the Company and certain of its other direct and indirect subsidiaries named therein, as guarantors, JPMorgan Chase Bank, N.A., as Administrative Agent, Citigroup Global Markets Inc., as Syndication Agent, J.P. Morgan Securities Inc. and Citigroup Global Markets Inc., as Joint Bookrunners and Co-Lead Arrangers, Citicorp North America, Inc., as Collateral Agent, Wachovia Bank, N.A., as Co-Syndication Agent, The Bank of Nova Scotia, Bank of America, N.A. and General Electric Capital Corporation, as Co-Documentation Agents, and the other lenders named therein (the "Second Extended DIP Facility"). The Second Extended DIP Facility, which was approved by the United States Bankruptcy Court for the Southern District of New York (the "Bankruptcy Court") on February 22, 2005, amends and restates in its entirety the Company's existing debtor-in-possession credit facility (the "First Extended DIP Facility").

The Second Extended DIP Facility matures upon the earlier of March 31, 2006 and the occurrence of certain other events, as described in the Second Extended DIP Facility. The Second Extended DIP Facility is comprised of an $800,000,000 revolving credit facility (including a $500,000,000 letter of credit subfacility) and a $500,000,000 term loan. The Second Extended DIP Facility is secured with a first priority lien on all of the Loan Parties' (as defined in the Second Extended DIP Facility) unencumbered assets, a priming first priority lien on all assets of the Loan Parties securing their pre-petition bank debt and a junior lien on all other assets of the Loan Parties. The applicable margin on loans extended under the Second Extended DIP Facility is 1.25% per annum in the case of Alternate Base Rate loans (which carry a base rate equal to the greatest of the Prime Rate, the Base CD Rate plus 1% or the Federal Funds Effective Rate plus .5%) and 2.25% per annum in the case of Adjusted LIBOR Rate loans. The Second Extended DIP Facility contains customary representations, warranties and covenants, including restrictive covenants which limit the ability of the Loan Parties to (i) incur additional guarantees, liens and indebtedness, (ii) sell or otherwise dispose of certain assets and (iii) pay dividends or make other distributions or payments with respect to any shares of capital stock, subject to certain exceptions set forth in the Second Extended DIP Facility. The Second Extended DIP Facility also requires compliance with certain financial covenants with respect to operating results and capital expenditures.

The foregoing summary of certain material terms of the Second Extended DIP Facility is qualified in its entirety by reference to the Second Extended DIP Facility, a copy of which is attached as Exhibit 10.1 to this Current Report on Form 8-K and is incorporated herein by reference.

As previously announced, a syndicate of financial institutions has committed to provide to the Company up to $8.8 billion in exit financing in connection with the Company's emergence from bankruptcy. Certain of the lenders and certain of the agents under the Second Extended DIP Facility are members of the syndicate of financial institutions that have committed to provide such exit financing to the Company. In addition, certain of the lenders and certain of the agents under the Second Extended DIP Facility were lenders and agents under certain of the Company's and its subsidiaries' pre-petition credit facilities. As previously announced, the Official Committee of Unsecured Creditors and the Official Committee of Equity Holders appointed in the bankruptcy cases of the Company and its subsidiaries previously have initiated or propose to initiate, respectively, an adversary proceeding against the lenders and agents under the Company's and its subsidiaries' pre-petition credit facilities. A more complete description of such adversary proceeding is set forth in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2003 (the "2003 Annual Report"), which was filed with the Securities and Exchange Commission on December 23,

2004. The foregoing summary of such adversary proceeding is qualified in its entirety by reference to the description of such adversary proceeding in the 2003 Annual Report.

Item 2.03. Creation of a Direction Financial Obligation or an Obligation under an Off-Balance Sheet Arrangement of a Registrant.

As set forth in Item 1.01 above, on February 25, 2005, the Company and certain of its subsidiaries, including the registrants, entered into and closed on the Second Extended DIP Facility. The total amount of credit available to the Loan Parties under the Second Extended DIP Facility is $1,300,000,000. In connection with the closing, the borrowers under the Second Extended DIP Facility borrowed an aggregate of $578,000,000, the proceeds from which were used to repay all of the indebtedness, including accrued and unpaid interest, and certain related fees and expenses, that were outstanding or payable, as applicable, under the First Extended DIP Facility. In addition, letters of credit with an aggregate face amount of approximately $112,188,000 that were issued under the First Extended DIP Facility were continued under the terms of the Second Extended DIP Facility. The principal amount of all loans made under the Second Extended DIP Facility will become due and payable on March 31, 2006, the maturity date of the Second Extended DIP Facility, subject to such loans being accelerated under the circumstances set forth in the Second Extended DIP Facility. The indebtedness outstanding under the Second Extended DIP Facility is subject to acceleration under certain circumstances, including (i) if any of the representations and warranties made by the Loan Parties therein or in related documents shall prove to have been false or misleading in any material respect when made, (ii) upon the failure by a borrower under the Second Extended DIP Facility to make any payment of principal in respect of any loan made thereunder as and when such amount becomes due and payable, (iii) subject to a grace period set forth in the Second Extended DIP Facility, the failure of any borrower thereunder to timely pay any fees, interest or other amounts due and payable thereunder, (iv) upon the failure of the Loan Parties to comply with the covenants set forth in the Second Extended DIP Facility (subject to certain grace periods in respect of certain covenants), (v) the entry by the Bankruptcy Court of an order granting relief from the automatic stay to the holder or holders of any security interest to permit foreclosure on any of the assets of a Loan Party that have a value in excess of $5,000,000 in the aggregate, (vi) the occurrence of a Change in Control (as defined in the Second Extended DIP Facility) without the consent of the requisite lenders under the Second Extended DIP Facility or (vii) if any judgment or order is entered against any Loan Party as to a post-petition liability or debt for the payment of money in excess of $5,000,000 and the enforcement thereof is not stayed or if a non-monetary judgment or order is entered against any Loan Party with respect to a post-petition event which does or would reasonably be expected to have a Material Adverse Effect (as defined in the Second Extended DIP Facility) and the enforcement of such non-monetary judgment or order is not stayed.

In accordance with general instruction B.2 of Form 8-K, the Adelphia Operating Report and the other information contained in this report (including exhibits) that is being furnished pursuant to Item 7.01 of Form 8-K shall not be deemed to be "filed" for the purposes of Section 18 of the Exchange Act or otherwise subject to liabilities of that section, nor shall they be deemed incorporated by reference in any filing under the Securities Act of 1933, as amended (the "Securities Act"), except as expressly set forth in such filing.

Cautionary Statement Regarding Financial and Operating Data

As a result of actions taken by management of the Company during the time that members of the Rigas family held senior executive positions: (a) the Company has not yet completed its financial statements as of and for the years ended December 31, 2003, 2002 and 2001, or received its independent public accountants' report thereon or filed with the Securities and Exchange Commission (the "Commission") its Annual Report on Form 10-K for the years ended December 31, 2003, 2002 and 2001; (b) the Company's former independent public accountants, Deloitte & Touche LLP, suspended their auditing work on the Company's financial statements as of and for the year ended December 31, 2001 and withdrew the audit reports it had issued with respect to the financial statements of the Company; (c) the Company has not yet completed its financial statements or filed with the Commission its Quarterly Reports on Form 10-Q as of and for the quarterly periods ended June 30, 2004, March 31, 2004, September 30, 2003, June 30, 2003 and March 31, 2003; (d) the Company has not yet completed its financial statements or filed with the Commission its Quarterly Reports on Form 10-Q as of and for the quarterly periods ended September 30, 2002, June 30, 2002 and March 31, 2002; and (e) the Company expects to restate its financial statements for the years ended December 31, 2000 and 1999, and possibly other periods. New management took control of the Company in May 2002, retained new independent auditors and began the preparation of financial statements for the periods in question. Current management believes that the public information provided by certain members of the Rigas family on other matters of interest to investors, such as the percentage of the Company's cable television systems that the Company believes have been upgraded to current standards, was unreliable. Until the completion of the restatement and the disclosure of restated financial results, previously reported financial information and other public information provided by the Rigas family should not be relied upon and information contained in this report may

have to be updated or supplemented. The Company is working to complete the restatement as promptly as possible and to obtain the opinion of its independent auditors on such restated financial statements. Receipt of an audit opinion with respect to the restated financial statements is a condition to consummation of the Company's proposed plan of reorganization and to consummation of the Company's proposed exit financing facilities.

Cautionary Statement Regarding Forward-Looking Statements

This report includes forward-looking statements within the meaning of Section 27A of the Securities Act and Section 21E of the Exchange Act. All statements regarding the Company's and its subsidiaries' and affiliates' expected future financial position, results of operations, cash flows, process for sale of the Company, restructuring and financing plans, expected emergence from bankruptcy, business strategy, budgets, projected costs, capital expenditures, network upgrades, products and services, competitive positions, growth opportunities, plans and objectives of management for future operations, as well as statements that include words such as "anticipate," "if," "believe," "plan," "estimate," "expect," "intend," "may," "could," "should," "will," and other similar expressions are forward-looking statements. Such forward-looking statements are inherently uncertain, and readers must recognize that actual results may differ materially from the Company's expectations. The Company does not undertake a duty to update such forward-looking statements. Factors that may cause actual results to differ materially from those in the forward-looking statements include those discussed under the heading "Risk Factors" in the 2003 Annual Report and the Company's pending bankruptcy proceeding, and its ongoing sale process, results of litigation against the Company and government investigations of the Company, the effects of government regulation including the actions of local cable franchising authorities, the availability of financing, actions of the Company's competitors, results and impacts of the process to sell the Company or its assets, ~~customer response to repackaged services,~~ pricing and availability of programming, equipment, supplies, and other inputs, the Company's ability to upgrade its network, technological developments, and changes in general economic conditions. Many of these factors are outside of the Company's control.
