         Employment Contracts and Termination of Employment

         During the year ended December 31, 1999, each of the named executive
officers (except for Mr. Milliard) had an employment agreement with the Company
which is automatically renewable each year unless one party gives the other
prior notice and which provides among other things for compensation review by
the Compensation Committee, the insurance premium payments listed in note (a)(i)
to the Summary Compensation Table above, and benefits. In addition, under such
employment agreements, upon termination of such employment for any reason other
than "for cause," each of the executive officers will be entitled to receive
severance pay equal to three months of his salary plus the amount of insurance
premiums payable under such officer's employment agreement which, as of January
1, 2000, in the aggregate in the case of John J. Rigas would be approximately
$334,137.

         The Company pays the annual premiums related to a split-dollar life
insurance arrangement for joint and survivor life insurance coverage for John J.
Rigas and his spouse. Upon the earlier of the death of Mr. Rigas and the death
of his spouse or the termination of the arrangement, the Company will recover
all of the premiums previously paid by the Company. The compensation related to
such arrangement is derived as described in notes (b)(ii) and (iii) to the
Summary Compensation Table above.

         Mr. Milliard served as President and Vice Chairman of Adelphia Business
Solutions. Mr. Milliard's employment agreement with Adelphia Business Solutions
provided for base salary, annual cash bonuses based on achievement, stock
options and stock bonuses, certain employee benefits and certain
change-in-control and other provisions, and was set to expire on March 31, 2001.
Mr. Milliard resigned as senior vice president and secretary of the Company and
as President and Secretary of Adelphia Business Solutions effective as of
September 20, 1999 although he continued to serve as a director of both
companies until the 1999 annual stockholders meeting on October 25, 1999. Mr.
Milliard will continue to receive payments under his employment agreement
through March 31, 2001 at the rate of his base salary at the time of his
resignation, which will total approximately $282,000 from January 1, 2000
through March 31, 2001, and will receive an option to purchase 81,250 shares of
Adelphia Business Solutions Class A common stock at fair market value on April
1, 2000. Certain other matters under Mr. Milliard's employment agreement remain
under discussion and negotiation by Mr. Milliard and Adelphia Business
Solutions.

Compensation Committee Interlocks and Insider Participation

         Perry S. Patterson and Pete J. Metros serve as members of the
Compensation Committee of the Board of Directors. Neither Mr. Patterson nor Mr.
Metros has been an officer or employee of the Company.

Board of Directors Compensation

         Directors who are not also employees of the Company each receive
compensation from the Company for services as a director at a rate of $750 plus
reimbursement of expenses for each Board and committee meeting attended.
Directors who are employees of the Company do not receive any compensation for
services as a director or as a member of Board committees.

(a) The holders of Class B common stock are deemed to be beneficial owners of an
equal number of shares of Class A common stock because Class B common stock is
convertible into Class A common stock on a one-to-one basis. See note (c) below.
In addition, the following persons own or have the power to direct the voting of
shares of Class A common stock in the following amounts: John J. Rigas, 431,800
shares - 71,700 shares directly and 360,100 shares through Doris Holdings, L.P.
("Doris"); Michael J. Rigas, 193,500 shares - 200 shares directly and 193,300
shares through Doris; Timothy J. Rigas, 193,500 shares - 200 shares directly and
193,300 shares through Doris; James P. Rigas, 193,300 shares through Doris. John
J. Rigas shares voting power with his spouse with respect to 106,300 of such
shares held through Doris. Each of John J. Rigas, Michael J. Rigas, Timothy J.
Rigas and James P. Rigas also shares voting and dispositive power with respect
to the 5,901,522 shares of Class B common stock owned by Highland 2000, L.P.,
the 18,490,230 shares of Class A common beneficially owned by Highland Holdings
and subsidiaries ("Highland"), the 4,000,000 shares of Class A common held by
Highland Holdings II ("Highland II") and the other 1,458,151 shares of Class A
common held by Doris. See notes (h) and (i).

(b) After giving effect to the conversion solely by each individual holder of
all of his Class B common stock into Class A common stock and including all
shares of Class A common stock, and the conversion into Class A common stock of
Series C Cumulative Convertible Preferred Stock, currently held by such
individual holder or over which such individual holder has or shares voting or
investment power as disclosed in notes (a) above or (h) and (i) below, the
percentage of Class A common stock owned by John J. Rigas, Michael J. Rigas,
Timothy J. Rigas and James P. Rigas would be 27.4%, 25.1%, 25.1% and 24.7%,
respectively. Further, after giving effect to an additional 4,919,340 shares of
Class A common stock of which John J. Rigas has the right to direct the voting
in the election of directors pursuant to a Class B Stockholders Agreement (and
assuming the parties to such agreement converted their Class B common stock into
Class A common stock), as to all of which additional shares John J. Rigas
disclaims beneficial ownership, the percentage of Class A common stock owned by
John J. Rigas would be 30.0%.

(c) The respective amounts shown include 97,949 of the same shares of Class B
common stock which are owned of record by Dorellenic, a general partnership in
which the five named individual Rigas family members are general partners and
5,901,522 of the same shares of Class B common stock which are owned by Highland
2000, L.P., a limited partnership in which the five named individual Rigas
family members are limited partners, and such shares are only included once for
"all executive officers and directors as a group." The named Rigas individuals
have shared voting and investment power with respect to these shares. The shares
of Class B common stock shown for Peter L. Venetis represent the shares
beneficially owned by his wife, Ellen K. Rigas. The amounts shown do not include
any of the 2,500,000 shares of Class B common stock that Highland has agreed to
purchase from Adelphia on or before July 2, 2000, pursuant to an agreement
between Adelphia and Highland dated October 1, 1999.

(d) Less than 1%.

(e) Peter L. Venetis is the husband of Ellen K. Rigas. As a result, he is deemed
to beneficially own indirectly the shares beneficially owned by Ellen K. Rigas.
Based upon 2,500 shares of Class A common stock owned directly by Mr. Venetis
and the shares of Class A common stock owned or deemed to be owned beneficially
by Ellen K. Rigas, the percentage of Class A common stock owned or deemed to be
beneficially owned by Mr. Venetis would be 22.3%. See notes (c), (f), (g) and
(i).

(f) As a holder of Class B common stock, Ellen K. Rigas is deemed to be the
beneficial owner of an equal number of shares of Class A common stock because
Class B common stock is convertible into Class A common stock on a one-to-one
basis. In addition, Ellen K. Rigas owns 1,600 shares of Class A common stock
directly and shares voting and investment power with respect to 18,490,230
shares of Class A common stock held by Highland and 4,000,000 shares of Class A
common stock held by Highland II. See also notes (c) and (i). Ellen K. Rigas is
the daughter of John J. Rigas.

(g) After giving effect to the conversion of all of Ellen K. Rigas' Class B
common stock into shares of Class A common stock and including all shares of

Item 13. Certain Relationships and Related Transactions

Management Services

         During the year ended December 31, 1999, the Company provided
management services for certain cable television systems not owned by the
Company, including managed partnerships ("Managed Partnerships") in which John
J. Rigas, Michael J. Rigas, Timothy J. Rigas, James P. Rigas and Ellen K. Rigas
had varied ownership interests. These services included supervision of technical
and business operations, accounting, marketing, programming, purchasing, field
engineering and other technical and administrative nonfield services. During
this period, the Managed Partnerships paid the Company up to five percent of
system revenues for such services. Other fees were charged by the Company to the
Managed Partnerships during this period for goods and services including
mark-ups on the Company's pay programming, placement fees associated with
pending acquisitions, and other goods and services. In addition, the Managed
Partnerships charged the Company for system and corporate costs during this
period. The net fees and expenses charged by the Company to Managed Partnerships
amounted to $5,136,000 for the year ended December 31, 1999. In addition, the
Company paid $11,227,000 to other entities owned by members of the Rigas family,
primarily for property, plant and equipment and services.

Loans to and from Affiliates

         Certain loans to and from the Company by or to affiliates as of

         During fiscal 1990 and 1991, the Company loaned an aggregate $255,000
to Daniel R. Milliard, a former officer and director, and an unaffiliated third
party, pursuant to several revolving term and term notes, for capital

         As of December 31, 1999, the Company had capital funding notes with
Niagara Frontier Hockey, L.P. ("NFHLP") of approximately $47,533,000. These
amounts represent advances to NFHLP plus accrued return of 14.0%. The return on
these capital funding notes amounted to approximately $3,800,000 for the year
ended December 31, 1999. The Rigas family is an affiliate of NFHLP and has
entered into an agreement to acquire all the voting interests of NFHLP.

Co-Borrowing Agreements

         On March 29, 1996, a subsidiary of the Company entered into a
$200,000,000 loan agreement with a Managed Partnership and an Olympus
subsidiary, as co-borrowers, which agreement remained in effect during the year
ended December 31, 1999.

         On May 6, 1999, certain subsidiaries and affiliates of Adelphia and
Olympus, including Hilton Head Communications, L.P., a Rigas family partnership,
closed on an $850,000,000 credit facility with several banks. The credit
facility consists of a $600,000,000 8 1/2 year reducing revolving credit loan
and a $250,000,000 9 year term loan, and remained in effect during the year
ended December 31, 1999.

Business Opportunities

         The Company's executive officers are parties to a Business Opportunity
Agreement, dated July 1, 1986 (the "Business Opportunity Agreement"), under
which they have agreed not to acquire an interest (except that such persons may,
individually for their own account, engage in regular portfolio trading of
publicly traded securities of companies in the cable television industry) in any
cable television system except: cable television systems which they or their
affiliates (excluding the Company) owned, in whole or in part, operated or had
agreed to acquire as of July 1, 1986; any expansions of such systems within the
same county or an adjacent county (except for systems which are also contiguous
to Company-owned systems); and systems which the Company elects not to acquire
under its right of first refusal described below and any expansions of such
systems within the same county or an adjacent county (except for systems which
are also contiguous to Company-owned systems). Otherwise, the executive officers
will first offer to the Company the opportunity to acquire or invest in any
cable television system or franchise therefor or interest therein that is
offered or available to them. If a majority of the Company's Board of Directors,
including a majority of the independent directors, rejects such offer, the
executive officers may acquire or invest in all of such cable television systems
or franchises therefor or interest therein or with others on terms no more
favorable to them than those offered to the Company.

         The Company's executive officers may from time to time evaluate and,
subject to the Company's rights and covenants in the Company's loan agreements
and indentures, may acquire cable television systems or interests therein for
their own accounts separately or along with the Company and/or other joint
venture parties.

         Except for the limitations on the ownership of cable television systems
as described herein, the executive officers of Adelphia and their affiliates are
not subject to limitations with respect to their other business activities and
may engage in other businesses related to cable television or other
telecommunications media. The executive officers will devote as much of their
time to the business of the Company as is reasonably required to fulfill the
duties of their offices.

         In the event that any executive officer (or his affiliate) decides to
offer for sale (other than to another executive officer or his or another
executive officer's family member, trust or family controlled entity) for his
account, his ownership interest in any cable television system or franchise, he
or it will (subject to the rights of third parties existing at such time) first
offer such interests to the Company. Such selling person or entity has a
unilateral option to elect to require that, if the Company accepts such offer,
up to one half of the consideration for his or its interest would consist of
shares of Class B common stock, which shares will be valued at the prevailing
market price of the Class A common stock, and the remainder would consist of
shares of Class A common stock and/or cash. If a majority of the Company's
independent directors rejects such offer, the executive officer (or his
affiliate) may sell such interest to third parties on terms no more favorable to
such third parties than those offered to the Company.

Registration Rights, Stock Purchase and Other Matters

         Pursuant to a Registration Rights Agreement, as amended, between the
Company and the holders of Class B common stock, John J. Rigas has the right,
subject to certain limitations, to require the Company to register shares of the
Company's common stock owned by him for sale to the public and pay the expenses
(except for Mr. Rigas' counsel fees) of such registration on five occasions
selected by him (subject to certain limitations intended to prevent undue
interference with the Company's ability to distribute its securities) during a
fourteen-year period which began in December 1986. The other holders of Class B
common stock have the right to participate, at the option of John J. Rigas, as
selling stockholders in any such registration initiated by John J. Rigas. The
holders of Class B common stock also have unlimited rights to participate as
selling stockholders in any registered public offering initiated by the Company
and require the Company to pay their expenses (except counsel fees). Such rights
of participation are subject to limitation at the discretion of the managing
underwriter of such offering.

         In addition, substantially all of the Class A common stock and Series C
Cumulative Convertible preferred stock owned by the Rigas family or entities
they own or control has been registered by the Company on shelf registration
statements which remain in effect.

         On January 14, 1999, Adelphia completed offerings totaling 8,600,000
shares of Class A common stock. In those offerings, Adelphia sold 4,600,000
newly issued shares, including an overallotment option for 600,000 shares, to
Goldman, Sachs & Co. at $43.25 per share and it also sold 4,000,000 shares at
$43.25 per share to Highland Holdings II, an entity controlled by members of the
Rigas family.

         On January 29, 1999, Adelphia purchased from Telesat Cablevision, Inc.,
("Telesat") a subsidiary of FPL Group, Inc., shares of Adelphia stock owned by
Telesat for a price of $149,213,000. In the transaction, Adelphia purchased
1,091,524 shares of its Class A common stock and 20,000 shares of its Series C
Cumulative convertible preferred stock which are convertible into an additional
2,358,490 shares of Class A common stock. These shares represent 3,450,014
shares of Class A common stock on a fully converted basis. On October 1, 1999,
the redemption of Telesat's interests in Olympus Communications, L.P. was
completed. The redemption was made for non-cash assets of Olympus of
approximately $100,000,000 pursuant to a January 1999 redemption agreement.
Prior to these transactions, Mr. Dennis Coyle was the nominee of Telesat to
Adelphia's Board of Directors.

         On March 2, 1999, Adelphia Business Solutions issued $300,000,000 of
12% Senior Subordinated Notes due 2007. Highland Holdings, an entity controlled
by members of the Rigas family, purchased $100,000,000 of the $300,000,000 of
Senior Subordinated Notes directly from Adelphia Business Solutions at a price
equal to the aggregate principal amount less the discount to the initial
purchasers of the other $200,000,000 of Senior Subordinated Notes.

         On April 9, 1999, Adelphia entered into a stock purchase agreement with
Highland Holdings in which Adelphia agreed to sell to Highland Holdings, and
Highland Holdings agreed to purchase $375,000,000 of Adelphia Class B common
stock. The purchase price per share for the Class B common stock was equal to
$60.76 (the public offering price in Adelphia's April 28, 1999 public offering,
less the underwriting discount), plus an interest factor. This transaction
closed on January 21, 2000. In addition, the Rigas family waived their rights
under the Business Opportunity Agreement to acquire certain basic subscribers in
the Philadelphia area in connection with Adelphia's acquisition, on October 1,
1999, of the cable television systems owned by Harron Communications Corp.

         On October 1, 1999, Adelphia entered into a stock purchase agreement
with Highland Holdings in which Adelphia agreed to sell to Highland Holdings and
Highland Holdings agreed to purchase $137,500,000 of Adelphia's Class B common
stock. The purchase price for the Class B common stock will be $55.00 per share,
which is equal to the public offering price less the underwriting discount in
the October 6, 1999 public offering of Class A common stock, plus an interest
factor. Closing under this stock purchase agreement is to occur by July 2, 2000
as determined by Highland Holdings at its discretion.

         The Company and Adelphia Business Solutions and members of or entities
controlled by the Rigas family have entered into various registration rights
agreements regarding the common stock and Senior Subordinated Notes owned by the
Rigas family.

         From time to time, the Company makes announcements regarding proposed
transactions that may involve affiliates of the Company. No assurance can be
given that these transactions will be consummated.
