NATIONSBANC MONTGOMERY SECURITIES LLC
As Representatives of the U.S. Underwriters
c/o Smith Barney Inc.
388 Greenwich Street
New York, New York 10013

Ladies & Gentlemen:

        Hyperion Telecommunications, Inc., a Delaware corporation (the
"Company"), proposes to issue and sell in the United States and Canada an
aggregate of 10,000,000 shares (the "Firm Shares") of its Class A Common Stock,
$.01 par value per share (the "Class A Common Stock"), to the several
Underwriters named in Schedule I hereto (the "U.S. Underwriters"), for whom
Smith Barney Inc., Credit Suisse First Boston and NationsBanc Montgomery
Securities LLC are acting as representatives (the "Representatives"). The
Company also proposes to sell to the U.S. Underwriters, upon the terms and
conditions set forth in Section 2 hereof, up to an additional 1,875,000 shares
(the "Additional Shares") of Class A Common Stock. The Firm Shares and the
Additional Shares are hereinafter collectively referred to as the "Shares."

        It is understood that the Company is concurrently entering into an
International Underwriting Agreement, dated the date hereof (the "International
Underwriting Agreement"), providing for the sale of 2,500,000 shares (the "Firm
International Shares") of the Class A Common Stock through arrangements with
certain underwriters outside the United States and Canada (the "Managers"), for
whom Smith Barney Inc., Credit Suisse First Boston (Europe) Limited and
NationsBanc Montgomery Securities LLC are acting as lead managers (the "Lead
Managers"). The Firm International Shares and the Shares, collectively, are
herein called the "Underwritten Shares."

        The Company also understands that the Representatives and the Lead
Managers have entered into an agreement (the "Agreement Between U.S.
Underwriters and Managers") contemplating the coordination of certain
transactions between the U.S. Underwriters and the Managers and that, pursuant
thereto and subject to the conditions set forth therein, the U.S. Underwriters
may purchase from the Managers a portion of the Firm International Shares or
sell to the Managers a portion of the Shares. The Company understands that any
such purchases and sales between the U.S. Underwriters and the Managers shall be
governed by the Agreement Between U.S. Underwriters and Managers and shall not
be governed by the terms of this Agreement or the International Underwriting
Agreement.
<PAGE>


        The Company wishes to confirm as follows its agreement with you and the
other several Managers on whose behalf you are acting, in connection with the
several purchases of the Shares by the Managers.

        1. Registration Statement and Prospectuses. The Company has prepared and
filed with the Securities and Exchange Commission (the "Commission") in
accordance with the provisions of the Securities Act of 1933, as amended, and
the rules and regulations of the Commission thereunder (collectively, the
"Act"), a registration statement on Form S-1 (File No. 333-48209) under the Act,
including prospectuses subject to completion, relating to the Underwritten
Shares. The term "Registration Statement" as used in this Agreement means the
registration statement (including all financial schedules and exhibits), as
amended at the time it becomes effective, and as thereafter amended by
post-effective amendment. The term "Prospectuses" as used in this Agreement
means the prospectuses in the forms included in the Registration Statement or,
if the prospectuses included in the Registration Statement omit information in
reliance on Rule 430A under the Act and such information is included in
prospectuses filed with the Commission pursuant to Rule 424(b) under the Act,
the term "Prospectuses" as used in this Agreement means the prospectuses in the
forms included in the Registration Statement as supplemented by the addition of
the Rule 430A information contained in the prospectuses filed with the
Commission pursuant to Rule 424(b). The term "Prepricing Prospectuses" as used
in this Agreement means the prospectuses subject to completion in the forms
included in the Registration Statement at the time of the initial filing of the
Registration Statement with the Commission, and as such prospectuses shall have
been amended from time to time prior to the date of the Prospectuses.

        It is understood that two forms of Prepricing Prospectus and two forms
of Prospectus are to be used in connection with the offering and sale of the
Underwritten Shares: a Prepricing Prospectus and a Prospectus relating to the
U.S. Shares that are to be offered and sold in the United States or Canada to
U.S. or Canadian Persons (the "U.S. Prepricing Prospectus" and the "U.S.
Prospectus," respectively), and a Prepricing Prospectus and a Prospectus
relating to the Shares that are to be offered and sold outside the United States
or Canada to persons other than U.S. or Canadian Persons (the "International
Prepricing Prospectus" and the "International Prospectus," respectively). The
U.S. Prospectus and the International Prospectus are herein collectively
referred to as the "Prospectuses," and the U.S. Prepricing Prospectus and the
International Prepricing Prospectus are herein called the "Prepricing
Prospectuses." For purposes of this Agreement: "Rules and Regulations" means the
rules and regulations adopted by the Commission under either the Act or the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), as applicable;
"U.S. or Canadian Person" means any resident or national of the United States or
Canada, any corporation, partnership or other entity created or organized in or
under the laws of the United States or Canada or any estate or trust the income
of which is subject to United States or Canadian income taxation regardless of
the source of its income (other than the foreign branch of any U.S. or Canadian
Person), and includes any United States or Canadian branch of a person other
than a U.S. or Canadian Person; "United States" means the United States of
America (including the states thereof and the District of Columbia) and its
territories, its possessions and other areas subject to its jurisdiction; and
"Canada" means Canada and its territories, its possessions and other areas
subject to its jurisdiction.

        2. Agreements to Sell and Purchase. The Company hereby agrees, subject
to all the terms and conditions set forth herein, to issue and sell to each
Manager and, upon the basis of the representations, warranties and agreements of
the Company herein contained and subject to all the terms and conditions set
forth herein, each Manager agrees, severally and not jointly, to purchase from
the Company, at a purchase price of $15.00 per Share (the "purchase price per
share"), the number of Shares set forth opposite the name of such Manager in
Schedule I hereto (or such number of Shares increased as set forth in Section 10
hereof).

        3. Terms of Public Offering. The Company has been advised by you that
the Managers propose to make a public offering of their respective portions of
<PAGE>

the Shares as soon after the Registration Statement and this Agreement have
become effective as in your judgment is advisable and initially to offer the
Shares upon the terms set forth in the International Prospectus.

        4. Delivery of the Shares and Payment Therefor. Delivery to the Managers
of and payment for the Shares shall be made at the office of Latham and Watkins,
885 Third Avenue, New York, New York 10022 at 10:00 A.M., New York City time, on
May 8, 1998 (the "Closing Date"). The place of closing for the Shares and the
Closing Date may be varied by agreement between you and the Company.

        Certificates for the Shares to be purchased hereunder shall be
registered in such names and in such denominations as you shall request prior to
9:30 A.M., New York City time, on the second business day preceding the Closing
Date. Such certificates shall be made available to you in New York City for
inspection and packaging not later than 9:30 A.M., New York City time, on the
business day next preceding the Closing Date. The certificates evidencing the
Shares to be purchased hereunder shall be delivered to you on the Closing Date,
against payment of the purchase price therefor in immediately available funds.

        5. Agreements of the Company. The Company agrees with the several
Managers as follows:

                  (a) If, at the time this Agreement is executed and delivered,
it is necessary for the Registration Statement or a post-effective amendment
thereto to be declared effective before the offering of the Shares may commence,
the Company will endeavor to cause the Registration Statement or such
post-effective amendment to become effective as soon as possible and will advise
you promptly and, if requested by you, will confirm such advice in writing, when
the Registration Statement or such post-effective amendment has become
effective.

                  (b) The Company will advise you promptly and, if requested by
you, will confirm such advice in writing: (i) of any request by the Commission
for amendment of or a supplement to the Registration Statement, the Prepricing
Prospectuses or the Prospectuses or for additional information; (ii) of the
issuance by the Commission of any stop order suspending the effectiveness of the
Registration Statement or of the suspension of qualification of the Shares for
offering or sale in any jurisdiction or the initiation of any proceeding for
such purpose; and (iii) within the period of time referred to in paragraph (f)
below, of the happening of any event which makes any statement of a material
fact made in the Registration Statement or the Prospectuses untrue or which
requires the making of any additions to or changes in the Registration Statement
or the Prospectuses in order to state a material fact required by the Act or the
regulations thereunder to be stated therein or necessary in order to make the
statements therein not misleading, or of the necessity to amend or supplement
the Prospectuses to comply with the Act or any other law. If at any time the
Commission shall issue any stop order suspending the effectiveness of the
Registration Statement, the Company will make every reasonable effort to obtain
the withdrawal of such order at the earliest possible time.

                  (c) The Company will furnish to you, without charge, four
signed copies of the Registration Statement as originally filed with the
Commission and of each amendment thereto, including financial statements and all
exhibits thereto, and will also furnish to you, without charge, such number of
conformed copies of the Registration Statement as originally filed and of each
amendment thereto, but without exhibits, as you may request.

                  (d) The Company will not (i) file any amendment to the
Registration Statement or make any amendment or supplement to the Prospectuses
of which you shall not previously have been advised or to which you shall object
after being so advised or (ii) so long as, in the written opinion of counsel for
the Managers, a prospectus is required to be delivered in connection with sales
<PAGE>

by any Manager or dealer, file any information, documents or reports pursuant to
the Exchange Act, without delivering a copy of such information, documents or
reports to you, as Lead Managers for the Managers, prior to or concurrently with
such filing.

                  (e) Prior to the execution and delivery of this Agreement, the
Company has delivered to you, without charge, in such quantities as you have
requested, copies of each form of the International Prepricing Prospectus. The
Company consents to the use, in accordance with the provisions of the Act and
with the securities or Blue Sky laws of the jurisdictions in which the Shares
are offered by the several Managers and by dealers, prior to the date of the
International Prospectus, of each International Prepricing Prospectus so
furnished by the Company.

                  (f) As soon after the execution and delivery of this Agreement
as possible and thereafter from time to time for such period as in the written
opinion of counsel for the Managers a prospectus is required by the Act to be
delivered in connection with sales by any Manager or dealer, the Company will
expeditiously deliver to each Manager and each dealer, without charge, as many
copies of the International Prospectus as you may request. The Company consents
to the use of the International Prospectus in accordance with the provisions of
the Act and with the securities or Blue Sky laws of the jurisdictions in which
the Shares are offered by the several Managers and by all dealers to whom Shares
may be sold, both in connection with the offering and sale of the Shares and for
such period of time thereafter as the International Prospectus is required by
the Act to be delivered in connection with sales by any Manager or dealer. If
during such period of time any event shall occur that in the judgment of the
Company or in the opinion of counsel for the Managers is required to be set
forth in the International Prospectus or should be set forth therein in order to
make the statements therein, in the light of the circumstances under which they
were made, not misleading, or if it is necessary to supplement or amend the
International Prospectus to comply with the Act or any other law, the Company
will forthwith prepare and, subject to the provisions of paragraph (d) above,
file with the Commission an appropriate supplement or amendment thereto and will
expeditiously furnish to the Managers and dealers a reasonable number of copies
thereof.

                  (g) The Company will cooperate with you and with counsel for
the Managers in connection with the registration or qualification of the Shares
for offering and sale by the several Managers and by dealers under the
securities or Blue Sky laws of such jurisdictions as you may designate and will
file such consents to service of process or other documents necessary or
appropriate in order to effect such registration or qualification; provided that
in no event shall the Company be obligated to qualify to do business in any
jurisdiction where it is not now so qualified or to take any action which would
subject it to service of process in suits, other than those arising out of the
offering or sale of the Shares, in any jurisdiction where it is not now so
subject.

                  (h) The Company will make generally available to its security
holders a consolidated earnings statement, which need not be audited, covering a
twelve-month period commencing after the effective date of the Registration
Statement and ending not later than 15 months thereafter, as soon as practicable
after the end of such period, which consolidated earnings statement shall
satisfy the provisions of Section 11(a) of the Act.

                  (i) During the period of five years after the date of this
Agreement, the Company will (i) make generally available a copy of each report
of the Company mailed to stockholders or filed with the Commission or the Nasdaq
National Market and will promptly notify you of such mailing or filing and (ii)
furnish to you from time to time such other information concerning the Company
and its Subsidiaries as you may request.

                  (j) If this Agreement shall terminate or shall be terminated
after execution pursuant to any provisions hereof (otherwise than pursuant to
the second paragraph of Section 10 hereof or by notice given by you terminating
<PAGE>
this Agreement pursuant to Section 10 or Section 11 hereof) or if this Agreement
shall be terminated by the Managers because of any failure or refusal on the
part of the Company to comply with the terms or fulfill any of the conditions of
this Agreement, the Company agrees to negotiate in good faith regarding the
reimbursement of the Lead Managers for all out-of-pocket expenses (including
fees and expenses of counsel for the Managers) incurred by you in connection
herewith.

                  (k) The Company will apply the net proceeds from the sale of
the Shares substantially in accordance with the description set forth in the
Prospectuses.

                  (l) If Rule 430A of the Act is employed, the Company will
timely file the Prospectuses pursuant to Rule 424(b) under the Act and will
advise you of the time and manner of such filing.

                  (m) For a period of 180 days after the date hereof (the
"Lock-up Period"), the Company will not, without the prior written consent of
Smith Barney Inc., offer, sell, contract to sell or otherwise dispose of any
Common Stock (or any securities convertible into or exchangeable for Common
Stock) or grant any options or warrants to purchase Common Stock, except for (i)
sales to the Managers pursuant to this Agreement and the U.S. Underwriters
pursuant to the U.S. Underwriting Agreement, (ii) the issuance of shares to
Adelphia Communications Corporation (the "Parent") in connection with the
Adelphia Note Contribution (as defined in the Prospectuses) and (iii) the
issuance of shares to the Parent in connection with the Adelphia Share Purchase
(as defined in the Prospectuses); (iv) the issuance of options or grants under
the Company's Long-Term Incentive Compensation Plan; (v) the issuance of the
Adelphia Warrant (as defined in the Prospectuses); (vi) the issuance of the
Additional MCI Warrants (as defined in the Prospectuses) and any other warrants
required to be issued by the Company in accordance with the Company's agreement
with MCImetro Access Transmission Services, Inc. or the Warrants (as defined 9n
the Prospectuses); (vii) the issuance of shares pursuant to the exercise of
warrants and options described in clauses (vi), (v) and (vi), the MCI Warrant
(as defined in the Prospectuses) and the Lenfest Warrant (as defined in the
Prospectuses); (viii) the issuance of Class B Common Stock upon the exercise of
outstanding Class B Warrants (as defined in the Prospectuses); and (ix) the
issuance of shares upon the conversion of Class B Common Stock..

                  (n) The Company has furnished or will furnish to you "lock-up"
letters, in form and substance satisfactory to you, signed by the Parent and
each of the Company's stockholders set forth on Schedule II hereto.

                  (o) Except as stated in this Agreement and in the U.S.
Underwriting Agreement and in the Prepricing Prospectuses and Prospectuses, the
Company has not taken, nor will it take, directly or indirectly, any action
designed to or that might reasonably be expected to cause or result in
stabilization or manipulation of the price of the Common Stock to facilitate the
sale or resale of the Shares.

                  (p) The Company will use its best efforts to have the Common
Stock listed, subject to notice of issuance, on the Nasdaq National Market
concurrently with the effectiveness of the Registration Statement.

        6. Representations and Warranties of the Company. The Company represents
and warrants to each Manager that:

                  (a) Each International Prepricing Prospectus included as part
of the Registration Statement as originally filed or as part of any amendment or
supplement thereto, or filed pursuant to Rule 424 under the Act, complied when
so filed in all material respects with the provisions of the Act; except that
this representation and warranty does not apply to statements in or omissions
<PAGE>

from such International Prepricing Prospectus made in reliance upon and in
conformity with information relating to any Manager or Manager furnished to the
Company in writing by a Manager through the Representatives or by a Manager
through the Lead Managers expressly for use therein. The Commission has not
issued any order preventing or suspending the use of any Prepricing Prospectus.

                  (b) The Registration Statement in the form in which it became
or becomes effective and also in such form as it may be when any post-effective
amendment thereto has or shall become effective and the Prospectuses and any
supplement or amendment thereto when filed with the Commission under Rule 424(b)
under the Act, complied or will comply in all material respects with the
provisions of the Act and did not or will not at any such times contain an
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 not misleading;
except that this representation and warranty does not apply to statements in or
omissions from the Registration Statement or the Prospectuses made in reliance
upon and in conformity with information relating to any Manager or Manager
furnished to the Company in writing by a Manager through the Representatives or
by a Manager through the Lead Managers expressly for use therein.

                  (c) All the outstanding shares of Common Stock of the Company

Statement and the Prospectuses.

                  (d) The Company has all requisite corporate power and

                  (e) Each of this Agreement and the U.S. Underwriting Agreement
has been duly and validly authorized, executed and delivered by the Company and
is the legal, valid and binding agreement of the Company, enforceable against
the Company in accordance with its terms, except insofar as indemnification and
contribution provisions may be limited by applicable law or public policy or
equitable principles and subject to applicable bankruptcy, insolvency,
fraudulent conveyance, reorganization or similar laws affecting the rights of
creditors generally and subject to general principles of equity.

                  (f) Each of the Company and its Subsidiaries (as defined) (A)

liability company, as applicable, in good standing under the laws of its

Prospectuses and to own, lease and operate its properties and (C) is duly
qualified and in good standing as a foreign corporation or limited liability
company, as applicable, authorized to do business in each jurisdiction in which
the nature of its business or its ownership or leasing of property requires such
qualification except, with respect to this clause (C), where the failure of the
Company and its Subsidiaries to be so qualified or in good standing does not and
could not reasonably be expected to (x) individually or in the aggregate, result
in a material adverse effect on the assets, liabilities, business, results of
operations, condition (financial or otherwise), cash flows, affairs or prospects
of the Company and the Subsidiaries, taken as a whole, (y) interfere with or
adversely affect the issuance or marketability of the Common Stock or (z) in any
manner draw into question the validity of this Agreement or the ability to
conduct its business in the manner set forth in the Registration Statements and
the Prospectuses (any of the events set forth in clauses (x), (y) or (z), a
"Material Adverse Effect"). The Company has no direct or indirect subsidiaries
<PAGE>

as of the Closing Date other than those set forth on Schedule III hereto
(referred to herein collectively as "Subsidiaries" and individually as a
"Subsidiary").

formed as a partnership, limited liability company or corporation, as
applicable, under the laws of its respective jurisdiction of formation, (B) has
all requisite partnership, limited liability company or corporate power and
authority, as applicable, to carry on its business as it is currently being

                  (h) All of the outstanding capital stock of each Subsidiary is
owned by the Company, free and clear of any security interest, claim, lien,
limitations on voting rights or other charge or encumbrance, other than security
interests, claims, liens, limitation on voting rights or other charges or
encumbrances arising from the pledge of the capital stock of the companies
pledged as security for the Company's 12 1/4% Senior Secured Notes due 2004.
Except as disclosed in the Prospectuses, there are not currently, and will not
be as a result of the transactions contemplated hereby, any outstanding
subscriptions, rights, warrants, calls, commitments of sale or options to

and regulations of the Federal Communications Commission (the "FCC") and
environmental laws, statutes, ordinances, rules, regulations, judgments or court
decrees) applicable to the Company, any Subsidiary, any Joint Venture or any of
their respective assets or properties (whether owned or leased) other than, in
the case of clauses (B) and (C), any default or violation that could not
reasonably be expected to have a Material Adverse Effect. There exists no
condition that, with notice, the passage of time or otherwise, would constitute
a default under any such document or instrument that could reasonably be
expected to have a Material Adverse Effect.

                  (j) There is (i) no action, suit or proceeding before or by
any court, arbitrator or governmental agency, body or official, domestic or
foreign, now pending or threatened or contemplated to which the Company, any of
the Subsidiaries or any of the Joint Ventures is or may be a party or to which
the business or property of the Company, any Subsidiary or any Joint Venture is
subject, (ii) no local, state or Federal law, statute, ordinance, rule,

be subject, that, in the case of clauses (i), (ii) and (iii) above, (y) is
required to be disclosed in the Registration Statement or the Prospectuses and
that is not so disclosed, or (z) could reasonably be expected to individually or
in the aggregate, result in a Material Adverse Effect.

                  (k) Neither the issuance and sale of the Shares, the
execution, delivery or performance by the Company of this Agreement or the U.S.
Underwriting Agreement by the Company, or the consummation by the Company of the
transactions contemplated hereby and thereby violate, conflict with or
constitute a breach of any of the terms or provisions of, or a default under (or
an event that with notice or the lapse of time, or both, would constitute a
default), or require consent under, or result in the imposition of a lien or
encumbrance on any properties of the Company, any Subsidiary or any Joint
Venture, or an acceleration of any indebtedness of the Company, any Subsidiary
or any Joint Venture pursuant to, (i) the charter or bylaws of the Company or
any Subsidiary or the partnership agreement or operating agreement governing any
Joint Venture, (ii) any bond, debenture, note, indenture, mortgage, deed of

any Joint Venture is a party or by which any of them or their property is or may
be bound, (iii) any local, state or Federal law, statute, ordinance, rule,

ordinances, rules or regulations) applicable to the Company, any Subsidiary, any
Joint Venture or any of their respective assets or properties or (iv) any

having jurisdiction over the Company, the Subsidiaries, the Joint Ventures or
any of their assets or properties, except in the case of clauses (ii), (iii) and

liens or accelerations that would not singly, or in the aggregate, have a
Material Adverse Effect. Other than as described in the Prospectuses, no
consent, approval, authorization or order of, or filing, registration,
qualification, license or permit of or with, (A) any court or governmental
agency, body or administrative agency (including, without limitation, the FCC)
or (B) any other person is required for (1) the execution, delivery and
performance by the Company of this Agreement or the U.S. Underwriting Agreement
or (2) the issuance and sale of the Shares and the transactions contemplated
hereby and thereby, except (x) such as have been obtained and made under the Act
and state securities or Blue Sky laws and regulations or such as may be required
by the NASD or (y) where the failure to obtain any such consent, approval,
authorization or order of, or filing registration, qualification, license or
permit would not reasonably be expected to result in a Material Adverse Effect.

                  (l) The accountants who have certified or shall certify the
financial statements included in the Registration Statement and the Prospectuses
are independent public accountants as required by the Act. The historical
financial statements of the Company and each of the Subsidiaries comply as to
form in all material respects with the requirements applicable to registration
statements on Form S-1 under the Act and present fairly in all material respects
the financial position and results of operations of the Company and each of its
Subsidiaries, at the respective dates and for the respective periods indicated.
Such financial statements have been prepared in accordance with generally
accepted accounting principles applied on a consistent basis throughout the

and each of its Joint Ventures, as applicable. The statistical information and
data included in the Prospectuses are accurately presented in all material
respects.

                  (m) The financial statements, together with related schedules
and notes, included in the Registration Statement and the Prospectuses, present
fairly the consolidated financial position, results of operations and changes in
financial position of the Company and the Subsidiaries on the basis stated in
the Registration Statement at the respective dates or for the respective periods
to which they apply; such statements and related schedules and notes have been
prepared in accordance with generally accepted accounting principles
consistently applied throughout the periods involved, except as disclosed
<PAGE>
therein; and the other financial and statistical information and data included
in the Registration Statement and the Prospectuses are accurately presented and
prepared on a basis consistent with such financial statements and the books and
records of the Company and the Subsidiaries.

                  (n) Except as disclosed in the Registration Statement and the
Prospectuses, subsequent to the respective dates as of which such information is

Company, any Subsidiary or any Joint Venture has incurred any liabilities or
obligations, direct or contingent, which are material, individually or in the
aggregate, to the Company, the Subsidiaries and the Joint Ventures taken as a
whole, not entered into any transaction not in the ordinary course of business,
(ii) there has not been, singly or in the aggregate, any change or development
which could reasonably be expected to result in a Material Adverse Effect, (iii)
there has been no dividend or distribution of any kind declared, paid or made by
the Company or its Subsidiaries on any class of capital stock and (iv) there has
been no distribution of profits or return of capital contribution by any Joint
Venture.

occur of (i) the Closing Date and (ii) completion of the distribution of the
Shares, will not distribute any offering material in connection with the
offering and sale of the Shares other than the Registration Statement, the
Prepricing Prospectuses, the Prospectuses or other materials, if any, permitted
by the Act.

                  (p) There is (i) no unfair labor practice complaint pending
against the Company, or any Joint Venture or threatened, before the National
Labor Relations Board, any state or local labor relations board or any foreign
labor relations board, and no significant grievance or significant arbitration
proceeding arising out of or under any collective bargaining agreement is so
pending or threatened against the Company, any Subsidiary or any Joint Venture,
(ii) no significant strike, labor dispute, slowdown or stoppage pending against
the Company, any Subsidiary or any Joint Venture threatened against the Company,
any Subsidiary or the Joint Venture and (iii) no union representation question
existing with respect to the employees of the Company, any Subsidiary or any
Joint Venture that, in the case of clauses (i), (ii) or (iii), could reasonably
be expected to result in a Material Adverse Effect. To the best of the Company's
knowledge, no collective bargaining organizing activities are taking place with
respect to the Company, the Subsidiaries or the Joint Ventures. None of the
Company, any Subsidiary or any Joint Venture has violated (A) any federal, state
or local law or foreign law relating to discrimination in hiring, promotion or
pay of employees, (B) any applicable wage or hour laws or (C) any provision of
the Employee Retirement Income Security Act of 1974, as amended ("ERISA"), or
the rules and regulations thereunder, which in the case of clause (A), (B) or
(C) above could reasonably be expected to result in a Material Adverse Effect.

                  (q) None of the Company, any Subsidiary or any Joint Venture
has violated any environmental, safety or similar law or regulation applicable
to it or its business or property relating to the protection of human health and
safety, the environment or hazardous or toxic substances or wastes, pollutants
or contaminants ("Environmental Laws"), lacks any permit, license or other
approval required of it under applicable Environmental Laws is violating any
term or condition of such permit, license or approval which could reasonably be
expected to, either individually or in the aggregate, have a Material Adverse
Effect.

                  (r) Each of the Company, the Subsidiaries and the Joint
Ventures has (i) good and marketable title to all of the properties and assets
described in the Prospectuses as owned by it, free and clear of all liens,
charges, encumbrances and restrictions, except such as are described in the
Prospectuses or as would not have a Material Adverse Effect, (ii) peaceful and
undisturbed possession under all leases to which any of them is a party as
lessee, (iii) all licenses, certificates, permits, authorizations, approvals,
franchises and other rights from, and has made all declarations and filings
with, all federal, state and local authorities (including, without limitation,
the FCC), all self-regulatory authorities and all courts and other tribunals
<PAGE>

(each an "Authorization") necessary to engage in the business as presently
conducted by any of them in the manner described in the Prospectuses, except as
described in the Prospectuses or where failure to hold such Authorizations would
not, individually or in the aggregate, have a Material Adverse Effect and (iv)
no reason to believe that any governmental body or agency is considering
limiting, suspending or revoking any such Authorization. Except where the
failure to be in full force and effect would not have a Material Adverse Effect,
all such Authorizations are valid and in full force and effect and each of the
Company, the Subsidiaries and the Joint Ventures is in compliance with the terms
and conditions of all such Authorizations and with the rules and regulations of
the regulatory authorities having jurisdiction with respect thereto. All leases
to which the Company, the Subsidiaries and the Joint Ventures is a party are
valid and binding and no default by the Company, any Subsidiary or any Joint
Venture has occurred and is continuing thereunder and no defaults by the
landlord are existing under any such lease that could reasonably be expected to
result in a Material Adverse Effect.

                  (s) Each of the Company, the Subsidiaries and the Joint
Ventures owns, possesses or has the right to employ all patents, patent rights,
licenses (including all FCC, state, local or other jurisdictional regulatory
licenses), inventions, copyrights, know-how (including trade secrets and other
unpatented and/or unpatentable proprietary or confidential information,
software, systems or procedures), trademarks, service marks and trade names,
inventions, computer programs, technical data and information (collectively, the
"Intellectual Property") presently employed by the Company, its Subsidiaries or
the Joint Ventures in connection with the businesses now operated by it or which
are proposed to be operated by the Company, its Subsidiaries or the Joint
Ventures free and clear of and without violating any right, claimed right,
charge, encumbrance, pledge, security interest, restriction or lien of any kind
of any other person and none of the Company, any Subsidiary or any Joint Venture
has received any notice of infringement of or conflict with asserted rights of
others with respect to any of the foregoing except as could not reasonably be
expected to have a Material Adverse Effect. The use of the Intellectual Property
in connection with the business and operations of the Company, the Subsidiaries
and the Joint Ventures does not infringe on the rights of any person, except
would not have a Material Adverse Effect.

                  (t) None of the Company, any Subsidiary, any Joint Venture or
any of their respective officers, directors, partners, employees, agents or
affiliates or any other person acting on behalf of the Company, any Subsidiary
or any Joint Venture, as the case may be, has, directly or indirectly, given or
agreed to give any money, gift or similar benefit (other than legal price
concessions to customers in the ordinary course of business) to any customer,
supplier, employee or agent of a customer or supplier, official or employee of
any governmental agency (domestic or foreign), instrumentality of any government
(domestic or foreign) or any political party or candidate for office (domestic
or foreign) or other person who was, is or may be in a position to help or
hinder the business of the Company, any Subsidiary or any Joint Venture (or
assist the Company, any Subsidiary or any Joint Venture in connection with any
actual or proposed transaction) which (i) might subject the Company, any
Subsidiary or any Joint Venture, or any other individual or entity to any damage
or penalty in any civil, criminal or governmental litigation or proceeding
(domestic or foreign), (ii) if not given in the past, could reasonably be
expected to have had a Material Adverse Effect on the assets, business or
operations of the Company, any Subsidiary or any Joint Venture or (iii) if not
continued in the future, could reasonably be expected to have a Material Adverse
Effect.

                  (u) All tax returns required to be filed by the Company, each
of the Subsidiaries and each of the Joint Ventures in all jurisdictions have
been so filed. All taxes, including withholding taxes, penalties and interest,
assessments, fees and other charges due or claimed to be due from such entities
or that are due and payable have been paid, other than those being contested in
good faith and for which adequate reserves have been provided or those currently
payable without penalty or interest. There are no proposed additional tax
assessments against the Company, any Subsidiary, any Joint Venture or the assets
or property of the Company, any Subsidiary or any Joint Venture.
<PAGE>

                  (v) None of the Company, the Subsidiaries or the Joint
Ventures is now, and after sale of the Shares to be sold by the Company
hereunder and application of the net proceeds from such sale as described in the
Prospectuses under the caption "Use of Proceeds" will not be (i) an "investment
company" or a company "controlled" by an "investment company" within the meaning
of the Investment Company Act of 1940, as amended (the "Investment Company
Act"), or (ii) a "holding company" or a "subsidiary company" or an "affiliate"
of a holding company within the meaning of the Public Utility Holding Company
Act of 1935, as amended (the "PUHC Act").

                  (w) Except as disclosed in the Prospectuses, there are no
holders of securities of the Company, the Subsidiaries or the Joint Ventures
who, by reason of the filing of the Registration Statement or consummation of
the transactions contemplated by this Agreement or the U.S. Underwriting
Agreement, have the right to request or demand that the Company, any of the
Subsidiaries or any of the Joint Ventures register any of its securities
(including, without limitation, Class A Common Stock and Class B Common Stock)
under the Act. No such rights with respect to any shares of Class A Common Stock
have been exercised as of the date hereof.

                  (x) Each of the Company, the Subsidiaries and the Joint
Ventures maintains a system of internal accounting controls sufficient to
provide reasonable assurance that: (i) transactions are executed in accordance
with management's general or specific authorizations; (ii) transactions are
recorded as necessary to permit preparation of financial statements in
conformity with generally accepted accounting principles and to maintain
accountability for assets; (iii) access to assets is permitted only in
accordance with management's general or specific authorization and (iv) the
recorded accountability for assets is compared with the existing assets at
reasonable intervals and appropriate action is taken with respect thereto.

                  (y) Each of the Company, the Subsidiaries and the Joint
Ventures maintains insurance covering its properties, operations, personnel and
businesses. Such insurance insures against such losses and risks as are adequate
in accordance with customary industry practice to protect the Company, the
Subsidiaries, the Joint Ventures and their respective businesses. None of the
Company, any Subsidiary or any Joint Venture has received notice from any
insurer or agent of such insurer that substantial capital improvements or other
expenditures will have to be made in order to continue such insurance. All such
insurance is outstanding and duly in force on the date hereof.

                  (z) None of the Company, any Subsidiary or any Joint Venture
has (i) taken, directly or indirectly, any action designed to, or that might
reasonably be expected to, cause or result in stabilization or manipulation of
the price of any security of the Company to facilitate the sale or resale of the
Class A Common Stock, (ii) since the date of the Prospectuses, (A) sold, bid
for, purchased or paid any person any compensation for soliciting purchases of
the Common Stock or (B) paid or agreed to pay to any person any compensation for
soliciting another to purchase any other securities of the Company.

                  (aa) Set forth on Exhibit A hereto is a list of each employee
pension or benefit plan with respect to which the Company or any corporation
considered an affiliate of the Company within the meaning of Section 407(d)(7)
of ERISA (an "ERISA Affiliate") is a party in interest or disqualified person.
The execution and delivery of this Agreement and the issuance and sale of the
Shares will not involve any prohibited transaction within the meaning of Section
406 of ERISA or Section 4975 of the Internal Revenue Code of 1986, as amended.

                  (bb) None of (A) the execution, delivery and performance of
this Agreement or the U.S. Underwriting Agreement, (B) the issuance and sale of
the Shares, (C) the application of the proceeds from the issuance and sale of
the Shares or (D) the consummation of the transactions contemplated in
connection with any of the foregoing as set forth in the Prospectuses, will
violate Regulations G, T, U or X promulgated by the Board of Governors of the
Federal Reserve System or analogous foreign laws and regulations.
<PAGE>
                  (cc) Except pursuant to this Agreement, there are no
contracts, agreements or understandings between the Company, any of its
Subsidiaries or any of its Joint Ventures and any other person that would give
rise to a valid claim against the Company or any of the Managers for a brokerage
commission, finder's fee or like payment in connection with the issuance,
purchase and sale of the Common Stock.

                  (dd) The Company has filed in a timely manner each document or
report required to be filed by it pursuant to the Exchange Act and the rules and
regulations thereunder; each such document or report at the time it was filed
conformed to the requirements of the Exchange Act and the rules and regulations
thereunder; and none or such documents or reports contained an untrue statement
of any material fact or omitted to state any material fact required to be stated
therein or necessary to make the statements therein not misleading.

                  (ee) Each of the Company, the Subsidiaries and the Joint
Ventures has complied with all provisions of Section 517.075, Florida Statutes,
relating to doing business with the Government of Cuba or with any affiliate
located in Cuba.

                  (ff) Except as disclosed in the Prospectuses, there are no
business relationships or related party transactions required to be disclosed
therein pursuant to Item 404 of Regulation S-K of the Commission.

                  The Company acknowledges that the Managers and, for purposes
of the opinions to be delivered to the Managers pursuant to Section 8(e), (f)
and (g) hereof, counsel to the Company and counsel to the Managers, will rely
upon the accuracy and truth of the foregoing representations and hereby consents
to such reliance.

        7. Indemnification and Contribution. (a) The Company agrees to indemnify
and hold harmless each of you and each other Manager and each person, if any,
who controls any Manager within the meaning of Section 15 of the Act or Section
20(a) of the Exchange Act from and against any and all losses, claims, damages,
liabilities and expenses (including reasonable costs of investigation) arising
out of or based upon any untrue statement or alleged untrue statement of a
material fact contained in any International Prepricing Prospectus or in the
Registration Statement or the International Prospectus or in any amendment or
supplement thereto, or arising out of or based upon any omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, except insofar as such
losses, claims, damages, liabilities or expenses arise out of or are based upon
any untrue statement or omission or alleged untrue statement or omission which
has been made therein or omitted therefrom in reliance upon and in conformity
with the information relating to such Manager furnished in writing to the
Company by any Manager through the Lead Managers expressly for use in connection
therewith; provided, however, that the indemnification contained in this
paragraph (a) with respect to any International Prepricing Prospectus shall not
inure to the benefit of any Manager (or to the benefit of any person controlling
such Manager) on account of any such loss, claim, damage, liability or expense
arising from the sale of the Shares by such Manager to any person if a copy of
the International Prospectus shall not have been delivered or sent to such
person within the time required by the Act and the regulations thereunder, and
the untrue statement or alleged untrue statement or omission or alleged omission
of a material fact contained in such International Prepricing Prospectus was
corrected in the International Prospectus, provided that the Company has
delivered the International Prospectus to the several Managers in requisite
quantity on a timely basis to permit such delivery or sending. The foregoing
indemnity agreement shall be in addition to any liability which the Company may
otherwise have.

        (b) If any action, suit or proceeding shall be brought against any
Manager or any person controlling any Manager in respect of which indemnity may
be sought against the Company, such Manager or such controlling person shall
<PAGE>

promptly notify the Company, and the Company shall assume the defense thereof,
including the employment of counsel and payment of all fees and expenses. Such
Manager or any such controlling person shall have the right to employ separate
counsel in any such action, suit or proceeding and to participate in the defense
thereof, but the fees and expenses of such counsel shall be at the expense of
such Manager or such controlling person unless (i) the Company has agreed in
writing to pay such fees and expenses, (ii) the Company has failed to assume the
defense and employ counsel, or (iii) the named parties to any such action, suit
or proceeding (including any impleaded parties) include both such Manager or
such controlling person, and the Company and such Manager or such controlling
person shall have been advised by its counsel that representation of such
indemnified party and the Company by the same counsel would be inappropriate
under applicable standards of professional conduct (whether or not such
representation by the same counsel has been proposed) due to actual or potential
differing interests between them (in which case the Company shall not have the
right to assume the defense of such action, suit or proceeding on behalf of such
Manager or such controlling person). It is understood, however, that the Company
shall, in connection with any one such action, suit or proceeding or separate
but substantially similar or related actions, suits or proceedings in the same
jurisdiction arising out of the same general allegations or circumstances, be
liable for the reasonable fees and expenses of only one separate firm of
attorneys (in addition to any local counsel) at any time for all such Managers
and controlling persons not having actual or potential differing interests with
you or among themselves, which firm shall be designated in writing by Smith
Barney Inc., and that all such fees and expenses shall be reimbursed as they are
incurred. The Company shall not be liable for any settlement of any such action,
suit or proceeding effected without its written consent, but if settled with
such written consent, or if there be a final judgment for the plaintiff in any
such action, suit or proceeding, the Company agrees to indemnify and hold
harmless any Manager, to the extent provided in the preceding paragraph, and any
such controlling person from and against any loss, claim, damage, liability or
expense by reason of such settlement or judgment.

        (c) Each Manager agrees, severally and not jointly, to indemnify and
hold harmless the Company, its directors, its officers who sign the Registration
Statement, and any person who controls the Company within the meaning of Section
15 of the Act or Section 20(a) of the Exchange Act, to the same extent as the
foregoing indemnity from the Company to each Manager, but only with respect to
information relating to such Manager furnished in writing by or on behalf of
such Manager through the Lead Managers expressly for use in the Registration
Statement, the International Prospectus or any International Prepricing
Prospectus, or any amendment or supplement thereto. If any action, suit or
proceeding shall be brought against the Company, any of its directors, any such
officer, or any such controlling person based on the Registration Statement, the
International Prospectus or any International Prepricing Prospectus, or any
amendment or supplement thereto, and in respect of which indemnity may be sought
against any Manager pursuant to this paragraph (c), such Manager shall have the
rights and duties given to the Company by paragraph (b) above (except that if
the Company shall have assumed the defense thereof such Manager shall not be
required to do so, but may employ separate counsel therein and participate in
the defense thereof, but the fees and expenses of such counsel shall be at such
Manager's expense), and the Company, its directors, any such officer, and any
such controlling person shall have the rights and duties given to the Managers
by paragraph (b) above. The foregoing indemnity agreement shall be in addition
to any liability which the Managers may otherwise have.

        (d) If the indemnification provided for in this Section 7 is unavailable
to an indemnified party under paragraphs (a) or (c) hereof in respect of any
losses, claims, damages, liabilities or expenses referred to therein, then an
indemnifying party, in lieu of indemnifying such indemnified party, shall
contribute to the amount paid or payable by such indemnified party as a result
of such losses, claims, damages, liabilities or expenses (i) in such proportion
as is appropriate to reflect the relative benefits received by the Company on
the one hand and the Managers on the other hand from the offering of the Shares,
or (ii) if the allocation provided by clause (i) above is not permitted by
applicable law, in such proportion as is appropriate to reflect not only the
<PAGE>
relative benefits referred to in clause (i) above but also the relative fault of
the Company on the one hand and the Managers on the other in connection with the
statements or omissions that resulted in such losses, claims, damages,
liabilities or expenses, as well as any other relevant equitable considerations.
The relative benefits received by the Company on the one hand and the Managers
on the other shall be deemed to be in the same proportion as the total net
proceeds from the offering (before deducting expenses) received by the Company
bear to the total underwriting discounts and commissions received by the
Managers, in each case as set forth in the table on the cover page of the
International Prospectus. The relative fault of the Company on the one hand and
the Managers on the other hand 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 by the Company on the one hand or by the Managers on the other hand and
the parties' relative intent, knowledge, access to information and opportunity
to correct or prevent such statement or omission.

        (e) The Company and the Managers agree that it would not be just and
equitable if contribution pursuant to this Section 7 were determined by a pro
rata allocation (even if the Managers were treated as one entity for such
purpose) or by any other method of allocation that does not take account of the
equitable considerations referred to in paragraph (d) above. The amount paid or
payable by an indemnified party as a result of the losses, claims, damages,
liabilities and expenses referred to in paragraph (d) above shall be deemed to
include, subject to the limitations set forth above, any legal or other expenses
reasonably incurred by such indemnified party in connection with investigating
any claim or defending any such action, suit or proceeding. Notwithstanding the
provisions of this Section 7, no Manager shall be required to contribute any
amount in excess of the amount by which the total price of the Shares
underwritten by it and distributed to the public exceeds the amount of any
damages which such Manager has otherwise been required to pay by reason of such
untrue or alleged untrue statement or omission or alleged omission. No person
guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of
the Act) shall be entitled to contribution from any person who was not guilty of
such fraudulent misrepresentation. The Managers' obligations to contribute
pursuant to this Section 7 are several in proportion to the respective numbers
of Shares set forth opposite their names in Schedule I hereto (or such numbers
of Shares increased as set forth in Section 10 hereof) and not joint.

        (f) No indemnifying party shall, without the prior written consent of
the indemnified party, effect any settlement of any pending or threatened
action, suit or proceeding in respect of which any indemnified party is or could
have been a party and indemnity could have been sought hereunder by such
indemnified party, unless such settlement includes an unconditional release of
such indemnified party from all liability on claims that are the subject matter
of such action, suit or proceeding.

        (g) Any losses, claims, damages, liabilities or expenses for which an
indemnified party is entitled to indemnification or contribution under this
Section 7 shall be paid by the indemnifying party to the indemnified party as
such losses, claims, damages, liabilities or expenses are incurred. The
indemnity and contribution agreements contained in this Section 7 and the
representations and warranties of the Company set forth in this Agreement shall
remain operative and in full force and effect, regardless of (i) any
investigation made by or on behalf of any Manager or any person controlling any
Manager, the Company, its directors or officers, or any person controlling the
Company, (ii) acceptance of any Shares and payment therefor hereunder, and (iii)
any termination of this Agreement. A successor to any Manager or any person

shall  become  effective:  (i) upon the
execution and delivery hereof by the parties hereto; or (ii) if, at the time
this Agreement is executed and delivered, it is necessary for the Registration
Statement or a post-effective amendment thereto to be declared effective before

Lead Managers for the several Managers, by notifying the Company.

             If any one or more of the Managers shall fail or refuse to purchase

and the aggregate number of Shares which such defaulting Manager or Managers are
obligated but fail or refuse to purchase is not more than one-tenth of the
aggregate number of Shares which the Managers are obligated to purchase on the
Closing Date, each non-defaulting Manager shall be obligated, severally, in the
proportion which the number of Shares set forth opposite its name in Schedule I
hereto bears to the aggregate number of Shares set forth opposite the names of
all non-defaulting Managers or in such other proportion as you may specify in

Managers shall fail or refuse to purchase Shares which it or they are obligated
to purchase on the Closing Date and the aggregate number of Shares with respect
to which such default occurs is more than one-tenth of the aggregate number of
Shares which the Managers are obligated to purchase on the Closing Date and
arrangements satisfactory to you and the Company for the purchase of such Shares
<PAGE>
by one or more non-defaulting Managers or other party or parties approved by you

will terminate without liability on the part of any non-defaulting Manager or
the Company. In any such case which does not result in termination of this
Agreement, either you or the Company shall have the right to postpone the
Closing Date, but in no event for longer than seven days, in order that the
required changes, if any, in the Registration Statement and the Prospectus or
any other documents or arrangements may be effected. Any action taken under this
paragraph shall not relieve any defaulting Manager from liability in respect of
any such default of any such Manager under this Agreement. The term "Manager" as
used in this Agreement includes, for all purposes of this Agreement, any party
not listed in Schedule I hereto who, with your approval and the approval of the
Company, purchases Shares which a defaulting Manager is obligated, but fails or
refuses, to purchase.

               Any notice under this Section 10 may be given by telegram,
telecopy or telephone but shall be subsequently confirmed by letter.

               11. Termination of Agreement. This Agreement shall be subject to
termination in your absolute discretion, without liability on the part of any
Manager to the Company, by notice to the Company, if prior to the Closing Date,
(i) trading in securities generally on the New York Stock Exchange, the American
Stock Exchange or the Nasdaq National Market shall have been suspended or
materially limited, (ii) a general moratorium on commercial banking activities
in New York or Philadelphia shall have been declared by either federal or state
authorities, or (iii) there shall have occurred any outbreak or escalation of
hostilities or other U.S. or domestic calamity, crisis or change in political,
financial or economic conditions, the effect of which on the financial markets
of the United States is such as to make it, in your judgment, impracticable or
inadvisable to commence or continue the offering of the Shares at the offering
price to the public set forth on the cover page of the International Prospectus
or to enforce contracts for the resale of the Shares by the Managers. Notice of
such termination may be given to the Company by telegram, telecopy or telephone
and shall be subsequently confirmed by letter.

               12. Information Furnished by the Managers. The statements set
forth in the last paragraph on the cover page, the stabilization legend on the
inside cover page, and the statements in the first, third, seventh, eighth,
ninth and fifteenth paragraphs under the caption "Underwriting" in any
International Prepricing Prospectus and in the International Prospectus,

through you as such information is referred to in Sections 6(b) and 7 hereof.

               13. Miscellaneous. Except as otherwise provided in Sections 5, 10
and 11 hereof, notice given pursuant to any provision of this Agreement shall be
in writing and shall be delivered (i) if to the Company, at the office of the
Company at Hyperion Telecommunications, Inc., Main at Water Street, Coudersport,
Pennsylvania 16915, Attention: Edward E. Babcock, Jr., Vice President, Finance;

several Managers, the Company, its directors and officers, and the other
controlling persons referred to in Section 7 hereof and their respective
successors and assigns, to the extent provided herein, and no other person shall
acquire or have any right under or by virtue of this Agreement. Neither the term
"successor" nor the term "successors and assigns" as used in this Agreement
shall include a purchaser from any Manager of any of the Shares in his status as
such purchaser.

               14. Applicable Law; Counterparts. This Agreement shall be
governed by and construed in accordance with the laws of the State of New York
applicable to contracts made and to be performed within the State of New York.

               This Agreement may be signed in various counterparts which
together constitute one and the same instrument. If signed in counterparts, this
Agreement shall not become effective unless at least one counterpart hereof

and in good standing as a foreign corporation or limited liability company, as
applicable, authorized to do business in each jurisdiction in which the nature
of its business or its ownership or leasing of property requires such
qualification, except where the failure to be so qualified would not, singly or
in the aggregate, have a material adverse effect on the business, financial
condition or results of operations of the Company and the Subsidiaries, taken as
a whole (a "Material Adverse Effect").

                  2. Each of the Joint Ventures has been duly incorporated or

the Prospectuses, and is duly qualified to transact business as a foreign
corporation, general partnership, limited partnership or limited liability
company, as applicable, in each jurisdiction in which the character of the
business being conducted by it or the location of the property owned by it makes
such qualification necessary, except where the failure to so qualify, singly or
in the aggregate, would not have a Material Adverse Effect. Each Joint Venture
that is a corporation, limited partnership or limited liability company is
validly existing and is in good standing under the laws of its jurisdiction of

                  13. The Registration Statement and all post-effective

Agreement and the International Underwriting Agreement have been duly
authorized, executed and delivered by the Company and is a legal, valid and
binding agreement of the Company, enforceable against the Company in accordance
with its terms, except that (A) enforceability may be limited by bankruptcy,
insolvency, reorganization, moratorium or other similar laws not or hereafter in
<PAGE>
effect relating to creditors' rights generally, (B) the remedy of specific
performance and other forms of equitable relief may be subject to certain
equitable defenses and to the discretion of the court before which the
proceedings may be brought and (C) rights to indemnity and contribution
thereunder may be limited by Federal or state securities laws or the public
policy underlying such laws.

                  15. All of the Joint Venture's limited partnership and limited
liability company interests owned by each Subsidiary have been duly authorized

of the partnership and limited liability company interests owned in the Joint
Ventures which are owned of record by each respective Subsidiary are, to the
best of our knowledge, owned free and clear of any security interest, lien or
other encumbrance.

                  16. All of the outstanding capital stock of each Subsidiary is
owned by the Company, free and clear of any security interest, claim, lien,
limitation on voting rights or encumbrance. There are not, to our knowledge,
other than as set forth in the Prospectuses, currently, and will not be
following the issuance and sale of the Shares, any outstanding subscriptions,
rights, warrants, calls, commitments of sale or options to acquire, or
instruments convertible into or exchangeable for, any capital stock or other
equity interest of the Company or any Subsidiary.

                  17. The Registration Statement and the Prospectuses and any
supplements or amendments thereto (except for the financial statements,
schedules, and notes thereto and other financial and statistical data included
therein, as to which such counsel need not express any opinion) comply as to
form in all material respects with the requirements of the Act.

                  18. Neither the issuance, sale or delivery of the Underwritten
Shares, nor the execution, delivery or performance of the U.S. Underwriting
Agreement or the International Underwriting Agreement, or compliance by the
Company with all provisions of the U.S. Agreement and the International
Underwriting Agreement, nor consummation by the Company of the transactions
contemplated in the U.S. Underwriting Agreement or by the International

authorization or order of, or filing, registration, qualification, license or

execution, delivery and performance by the Company of the International

                  Although we have not undertaken, except as otherwise indicated
in our opinion, to determine independently, and do not assume any responsibility
for, the accuracy, completeness or fairness of the statements in the
Registration Statement, we have participated in the preparation of the
Registration Statement and the Prospectuses, including general review and
discussion of the contents thereof but have made no independent check or
verification thereof, and no facts have come to our attention that would lead us
to believe that the Registration Statement at the time the Registration
Statement became effective, or the Prospectuses, as of their respective dates
and as of the Closing Date, contained an untrue statement of a material fact or
omitted to state a material fact required to be stated in the Prospectuses or
necessary to make the statements therein, in the light of the circumstances
under which they were made, not misleading or that any amendment or supplement
to the Prospectuses, as of their respective dates, and as of the Closing Date,
contained any untrue statement of a material fact or omitted to state a material
fact required to be stated in the Prospectuses or necessary in order to make the
statements in the Prospectuses, in the light of the circumstances under which
they were made, not misleading (it being understood that such counsel need
express no opinion with respect to the financial statements, schedules, pro
<PAGE>
forma financial statements and the notes thereto and other financial data
included in the Registration Statement and the Prospectuses.

"Company"), proposes to issue and sell outside the United States and Canada an
aggregate of 2,5000,000 shares (the "Shares") of its Class A Common Stock, $.01
par value per share (the "Class A Common Stock"), to the several underwriters
named in Schedule I hereto (the "Managers"), for whom Smith Barney Inc., Credit
Suisse First Boston (Europe) Limited and NationsBanc Montgomery Securities LLC
are acting as representatives (the "Lead Managers").

        It is understood that the Company is concurrently entering into a U.S.
Underwriting Agreement, dated the date hereof (the "U.S. Underwriting
Agreement"), providing for the sale of 10,000,000 shares (the "Firm U.S.
Shares") of the Class A Common Stock (plus an option granted to purchase up to
an additional 1,875,000 shares of Class A Common Stock (the "Additional U.S.
Shares")) solely for the purpose of covering over-allotments) through
arrangements with certain underwriters in the United States and Canada (the
"U.S. Underwriters"), for whom Smith Barney Inc., Credit Suisse First Boston
Corporation and NationsBanc Montgomery Securities LLC are acting as
representatives (the " Representatives"). All shares of Class A Common Stock
proposed to be offered to the U.S Underwriters pursuant to the U.S. Underwriting
Agreement, including the Firm U.S. Shares and the Additional U.S. Shares, are
herein called the "U.S. Shares"; the U.S. Shares and the Shares, collectively,
are herein called the "Underwritten Shares."

        The Company also understands that the Lead Managers and the
Representatives have entered into an agreement (the "Agreement Between U.S.
Underwriters and Managers") contemplating the coordination of certain
transactions between the Managers and the U.S. Underwriters and that, pursuant
thereto and subject to the conditions set forth therein, the Managers may
purchase from the U.S. Underwriters a portion of the U.S. Shares or sell to the
U.S. Underwriters a portion of the Shares. The Company understands that any such
purchases and sales between the Managers and the U.S. Underwriters shall be
governed by the Agreement Between Managers and U.S. Underwriters and shall not
be governed by the terms of this Agreement or the U.S. Underwriting Agreement.
<PAGE>

        The Company wishes to confirm as follows its agreement with you and the
other several Managers on whose behalf you are acting, in connection with the
several purchases of the Shares by the Managers.

        1. Registration Statement and Prospectuses. The Company has prepared and
filed with the Securities and Exchange Commission (the "Commission") in
accordance with the provisions of the Securities Act of 1933, as amended, and
the rules and regulations of the Commission thereunder (collectively, the
"Act"), a registration statement on Form S-1 (File No. 333-48209) under the Act,
including prospectuses subject to completion, relating to the Underwritten
Shares. The term "Registration Statement" as used in this Agreement means the
registration statement (including all financial schedules and exhibits), as
amended at the time it becomes effective, and as thereafter amended by
post-effective amendment. The term "Prospectuses" as used in this Agreement
means the prospectuses in the forms included in the Registration Statement or,
if the prospectuses included in the Registration Statement omit information in
reliance on Rule 430A under the Act and such information is included in
prospectuses filed with the Commission pursuant to Rule 424(b) under the Act,
the term "Prospectuses" as used in this Agreement means the prospectuses in the
forms included in the Registration Statement as supplemented by the addition of
the Rule 430A information contained in the prospectuses filed with the
Commission pursuant to Rule 424(b). The term "Prepricing Prospectuses" as used
in this Agreement means the prospectuses subject to completion in the forms
included in the Registration Statement at the time of the initial filing of the
Registration Statement with the Commission, and as such prospectuses shall have
been amended from time to time prior to the date of the Prospectuses.

        It is understood that two forms of Prepricing Prospectus and two forms
of Prospectus are to be used in connection with the offering and sale of the
Underwritten Shares: a Prepricing Prospectus and a Prospectus relating to the
U.S. Shares that are to be offered and sold in the United States or Canada to
U.S. or Canadian Persons (the "U.S. Prepricing Prospectus" and the "U.S.
Prospectus," respectively), and a Prepricing Prospectus and a Prospectus
relating to the Shares that are to be offered and sold outside the United States
or Canada to persons other than U.S. or Canadian Persons (the "International
Prepricing Prospectus" and the "International Prospectus," respectively). The
U.S. Prospectus and the International Prospectus are herein collectively
referred to as the "Prospectuses," and the U.S. Prepricing Prospectus and the
International Prepricing Prospectus are herein called the "Prepricing
Prospectuses." For purposes of this Agreement: "Rules and Regulations" means the
rules and regulations adopted by the Commission under either the Act or the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), as applicable;
"U.S. or Canadian Person" means any resident or national of the United States or
Canada, any corporation, partnership or other entity created or organized in or
under the laws of the United States or Canada or any estate or trust the income
of which is subject to United States or Canadian income taxation regardless of
the source of its income (other than the foreign branch of any U.S. or Canadian
Person), and includes any United States or Canadian branch of a person other
than a U.S. or Canadian Person; "United States" means the United States of
America (including the states thereof and the District of Columbia) and its
territories, its possessions and other areas subject to its jurisdiction; and
"Canada" means Canada and its territories, its possessions and other areas
subject to its jurisdiction.

        2. Agreements to Sell and Purchase. The Company hereby agrees, subject
to all the terms and conditions set forth herein, to issue and sell to each
Manager and, upon the basis of the representations, warranties and agreements of
the Company herein contained and subject to all the terms and conditions set
forth herein, each Manager agrees, severally and not jointly, to purchase from
the Company, at a purchase price of $15.00 per Share (the "purchase price per
share"), the number of Shares set forth opposite the name of such Manager in
Schedule I hereto (or such number of Shares increased as set forth in Section 10
hereof).

        3. Terms of Public Offering. The Company has been advised by you that
the Managers propose to make a public offering of their respective portions of
<PAGE>

the Shares as soon after the Registration Statement and this Agreement have
become effective as in your judgment is advisable and initially to offer the
Shares upon the terms set forth in the International Prospectus.

        4. Delivery of the Shares and Payment Therefor. Delivery to the Managers
of and payment for the Shares shall be made at the office of Latham and Watkins,
885 Third Avenue, New York, New York 10022 at 10:00 A.M., New York City time, on
May 8, 1998 (the "Closing Date"). The place of closing for the Shares and the
Closing Date may be varied by agreement between you and the Company.

        Certificates for the Shares to be purchased hereunder shall be
registered in such names and in such denominations as you shall request prior to
9:30 A.M., New York City time, on the second business day preceding the Closing
Date. Such certificates shall be made available to you in New York City for

business day next preceding the Closing Date. The certificates evidencing the
Shares to be purchased hereunder shall be delivered to you on the Closing Date,
against payment of the purchase price therefor in immediately available funds.

        5. Agreements of the Company. The Company agrees with the several
Managers as follows:

                  (a) If, at the time this Agreement is executed and delivered,
it is necessary for the Registration Statement or a post-effective amendment
thereto to be declared effective before the offering of the Shares may commence,
the Company will endeavor to cause the Registration Statement or such
post-effective amendment to become effective as soon as possible and will advise
you promptly and, if requested by you, will confirm such advice in writing, when
the Registration Statement or such post-effective amendment has become
effective.

                  (b) The Company will advise you promptly and, if requested by
you, will confirm such advice in writing: (i) of any request by the Commission
for amendment of or a supplement to the Registration Statement, the Prepricing
Prospectuses or the Prospectuses or for additional information; (ii) of the
issuance by the Commission of any stop order suspending the effectiveness of the
Registration Statement or of the suspension of qualification of the Shares for
offering or sale in any jurisdiction or the initiation of any proceeding for
such purpose; and (iii) within the period of time referred to in paragraph (f)
below, of the happening of any event which makes any statement of a material
fact made in the Registration Statement or the Prospectuses untrue or which
requires the making of any additions to or changes in the Registration Statement
or the Prospectuses in order to state a material fact required by the Act or the
regulations thereunder to be stated therein or necessary in order to make the
statements therein not misleading, or of the necessity to amend or supplement
the Prospectuses to comply with the Act or any other law. If at any time the
Commission shall issue any stop order suspending the effectiveness of the
Registration Statement, the Company will make every reasonable effort to obtain
the withdrawal of such order at the earliest possible time.

                  (c) The Company will furnish to you, without charge, four
signed copies of the Registration Statement as originally filed with the
Commission and of each amendment thereto, including financial statements and all
exhibits thereto, and will also furnish to you, without charge, such number of
conformed copies of the Registration Statement as originally filed and of each
amendment thereto, but without exhibits, as you may request.

                  (d) The Company will not (i) file any amendment to the
Registration Statement or make any amendment or supplement to the Prospectuses
of which you shall not previously have been advised or to which you shall object
after being so advised or (ii) so long as, in the written opinion of counsel for
the Managers, a prospectus is required to be delivered in connection with sales
by any Manager or dealer, file any information, documents or reports pursuant to
<PAGE>
the Exchange Act, without delivering a copy of such information, documents or
reports to you, as Lead Managers for the Managers, prior to or concurrently with
such filing.

                  (e) Prior to the execution and delivery of this Agreement, the
Company has delivered to you, without charge, in such quantities as you have
requested, copies of each form of the International Prepricing Prospectus. The
Company consents to the use, in accordance with the provisions of the Act and
with the securities or Blue Sky laws of the jurisdictions in which the Shares
are offered by the several Managers and by dealers, prior to the date of the
International Prospectus, of each International Prepricing Prospectus so
furnished by the Company.

                  (f) As soon after the execution and delivery of this Agreement
as possible and thereafter from time to time for such period as in the written
opinion of counsel for the Managers a prospectus is required by the Act to be
delivered in connection with sales by any Manager or dealer, the Company will
expeditiously deliver to each Manager and each dealer, without charge, as many
copies of the International Prospectus as you may request. The Company consents
to the use of the International Prospectus in accordance with the provisions of
the Act and with the securities or Blue Sky laws of the jurisdictions in which
the Shares are offered by the several Managers and by all dealers to whom Shares
may be sold, both in connection with the offering and sale of the Shares and for
such period of time thereafter as the International Prospectus is required by
the Act to be delivered in connection with sales by any Manager or dealer. If
during such period of time any event shall occur that in the judgment of the
Company or in the opinion of counsel for the Managers is required to be set
forth in the International Prospectus or should be set forth therein in order to
make the statements therein, in the light of the circumstances under which they
were made, not misleading, or if it is necessary to supplement or amend the
International Prospectus to comply with the Act or any other law, the Company
will forthwith prepare and, subject to the provisions of paragraph (d) above,
file with the Commission an appropriate supplement or amendment thereto and will
expeditiously furnish to the Managers and dealers a reasonable number of copies
thereof.

                  (g) The Company will cooperate with you and with counsel for
the Managers in connection with the registration or qualification of the Shares
for offering and sale by the several Managers and by dealers under the
securities or Blue Sky laws of such jurisdictions as you may designate and will
file such consents to service of process or other documents necessary or
appropriate in order to effect such registration or qualification; provided that
in no event shall the Company be obligated to qualify to do business in any
jurisdiction where it is not now so qualified or to take any action which would
subject it to service of process in suits, other than those arising out of the
offering or sale of the Shares, in any jurisdiction where it is not now so
subject.

                  (h) The Company will make generally available to its security
holders a consolidated earnings statement, which need not be audited, covering a
twelve-month period commencing after the effective date of the Registration
Statement and ending not later than 15 months thereafter, as soon as practicable
after the end of such period, which consolidated earnings statement shall
satisfy the provisions of Section 11(a) of the Act.

                  (i) During the period of five years after the date of this
Agreement, the Company will (i) make generally available a copy of each report
of the Company mailed to stockholders or filed with the Commission or the Nasdaq
National Market and will promptly notify you of such mailing or filing and (ii)
furnish to you from time to time such other information concerning the Company
and its Subsidiaries as you may request.

                  (j) If this Agreement shall terminate or shall be terminated
after execution pursuant to any provisions hereof (otherwise than pursuant to
the second paragraph of Section 10 hereof or by notice given by you terminating
<PAGE>
this Agreement pursuant to Section 10 or Section 11 hereof) or if this Agreement
shall be terminated by the Managers because of any failure or refusal on the
part of the Company to comply with the terms or fulfill any of the conditions of
this Agreement, the Company agrees to negotiate in good faith regarding the
reimbursement of the Lead Managers for all out-of-pocket expenses (including
fees and expenses of counsel for the Managers) incurred by you in connection
herewith.

                  (k) The Company will apply the net proceeds from the sale of
the Shares substantially in accordance with the description set forth in the
Prospectuses.

                  (l) If Rule 430A of the Act is employed, the Company will
timely file the Prospectuses pursuant to Rule 424(b) under the Act and will
advise you of the time and manner of such filing.

                  (m) For a period of 180 days after the date hereof (the
"Lock-up Period"), the Company will not, without the prior written consent of
Smith Barney Inc., offer, sell, contract to sell or otherwise dispose of any
Common Stock (or any securities convertible into or exchangeable for Common
Stock) or grant any options or warrants to purchase Common Stock, except for (i)
sales to the Managers pursuant to this Agreement and the U.S. Underwriters
pursuant to the U.S. Underwriting Agreement, (ii) the issuance of shares to
Adelphia Communications Corporation (the "Parent") in connection with the
Adelphia Note Contribution (as defined in the Prospectuses) and (iii) the
issuance of shares to the Parent in connection with the Adelphia Share Purchase

outstanding Class B Warrants (as defined in the Prospectuses); and (ix) the
issuance of shares upon the conversion of Class B Common Stock..

                  (n) The Company has furnished or will furnish to you "lock-up"
letters, in form and substance satisfactory to you, signed by the Parent and
each of the Company's stockholders set forth on Schedule II hereto.

                  (o) Except as stated in this Agreement and in the U.S.
Underwriting Agreement and in the Prepricing Prospectuses and Prospectuses, the
Company has not taken, nor will it take, directly or indirectly, any action
designed to or that might reasonably be expected to cause or result in
stabilization or manipulation of the price of the Common Stock to facilitate the
sale or resale of the Shares.

                  (p) The Company will use its best efforts to have the Common
Stock listed, subject to notice of issuance, on the Nasdaq National Market
concurrently with the effectiveness of the Registration Statement.

        6. Representations and Warranties of the Company. The Company represents

under the Act, complied or will comply in all material respects with the
provisions of the Act and did not or will not at any such times contain an
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 not misleading;
except that this representation and warranty does not apply to statements in or
omissions from the Registration Statement or the Prospectuses made in reliance
upon and in conformity with information relating to any Manager or Manager

company, as applicable, authorized to do business in each jurisdiction in which
the nature of its business or its ownership or leasing of property requires such

could not reasonably be expected to (x) individually or in the aggregate, result
in a material adverse effect on the assets, liabilities, business, results of
operations, condition (financial or otherwise), cash flows, affairs or prospects
of the Company and the Subsidiaries, taken as a whole, (y) interfere with or

"Material Adverse Effect"). The Company has no direct or indirect subsidiaries

"Subsidiary").

failure to be so qualified or in good standing does not and could not reasonably
be expected to result in a Material Adverse Effect. Neither the Company nor its
Subsidiaries has any ownership interest in any Joint Venture other than those
set forth on Schedule IV hereto (referred to herein collectively as "Joint
Ventures" and individually a "Joint Venture").

                  (h) All of the outstanding capital stock of each Subsidiary is
owned by the Company, free and clear of any security interest, claim, lien,
limitations on voting rights or other charge or encumbrance, other than security
interests, claims, liens, limitation on voting rights or other charges or
encumbrances arising from the pledge of the capital stock of the companies
pledged as security for the Company's 12 1/4% Senior Secured Notes due 2004.

and regulations of the Federal Communications Commission (the "FCC") and
environmental laws, statutes, ordinances, rules, regulations, judgments or court
decrees) applicable to the Company, any Subsidiary, any Joint Venture or any of
their respective assets or properties (whether owned or leased) other than, in
the case of clauses (B) and (C), any default or violation that could not
reasonably be expected to have a Material Adverse Effect. There exists no
condition that, with notice, the passage of time or otherwise, would constitute
a default under any such document or instrument that could reasonably be
expected to have a Material Adverse Effect.

                  (j) There is (i) no action, suit or proceeding before or by
any court, arbitrator or governmental agency, body or official, domestic or
foreign, now pending or threatened or contemplated to which the Company, any of

execution, delivery or performance by the Company of this Agreement or the U.S.
Underwriting Agreement by the Company, or the consummation by the Company of the
transactions contemplated hereby and thereby violate, conflict with or
constitute a breach of any of the terms or provisions of, or a default under (or
an event that with notice or the lapse of time, or both, would constitute a
default), or require consent under, or result in the imposition of a lien or
encumbrance on any properties of the Company, any Subsidiary or any Joint
Venture, or an acceleration of any indebtedness of the Company, any Subsidiary
or any Joint Venture pursuant to, (i) the charter or bylaws of the Company or
any Subsidiary or the partnership agreement or operating agreement governing any

Material Adverse Effect. Other than as described in the Prospectuses, no
consent, approval, authorization or order of, or filing, registration,
qualification, license or permit of or with, (A) any court or governmental
agency, body or administrative agency (including, without limitation, the FCC)
or (B) any other person is required for (1) the execution, delivery and
performance by the Company of this Agreement or the U.S. Underwriting Agreement
or (2) the issuance and sale of the Shares and the transactions contemplated
hereby and thereby, except (x) such as have been obtained and made under the Act
and state securities or Blue Sky laws and regulations or such as may be required
by the NASD or (y) where the failure to obtain any such consent, approval,
authorization or order of, or filing registration, qualification, license or
permit would not reasonably be expected to result in a Material Adverse Effect.

financial statements included in the Registration Statement and the Prospectuses
are independent public accountants as required by the Act. The historical
financial statements of the Company and each of the Subsidiaries comply as to
form in all material respects with the requirements applicable to registration

Company, any Subsidiary or any Joint Venture has incurred any liabilities or
obligations, direct or contingent, which are material, individually or in the
aggregate, to the Company, the Subsidiaries and the Joint Ventures taken as a
whole, not entered into any transaction not in the ordinary course of business,
(ii) there has not been, singly or in the aggregate, any change or development

Shares, will not distribute any offering material in connection with the

Prepricing Prospectuses, the Prospectuses or other materials, if any, permitted
by the Act.

                  (p) There is (i) no unfair labor practice complaint pending
against the Company, or any Joint Venture or threatened, before the National
Labor Relations Board, any state or local labor relations board or any foreign
labor relations board, and no significant grievance or significant arbitration
proceeding arising out of or under any collective bargaining agreement is so
pending or threatened against the Company, any Subsidiary or any Joint Venture,

the Company, any Subsidiary or any Joint Venture threatened against the Company,
any Subsidiary or the Joint Venture and (iii) no union representation question
existing with respect to the employees of the Company, any Subsidiary or any
Joint Venture that, in the case of clauses (i), (ii) or (iii), could reasonably
be expected to result in a Material Adverse Effect. To the best of the Company's
knowledge, no collective bargaining organizing activities are taking place with
respect to the Company, the Subsidiaries or the Joint Ventures. None of the
Company, any Subsidiary or any Joint Venture has violated (A) any federal, state
or local law or foreign law relating to discrimination in hiring, promotion or
pay of employees, (B) any applicable wage or hour laws or (C) any provision of
the Employee Retirement Income Security Act of 1974, as amended ("ERISA"), or
the rules and regulations thereunder, which in the case of clause (A), (B) or
(C) above could reasonably be expected to result in a Material Adverse Effect.

                  (q) None of the Company, any Subsidiary or any Joint Venture
has violated any environmental, safety or similar law or regulation applicable
to it or its business or property relating to the protection of human health and
safety, the environment or hazardous or toxic substances or wastes, pollutants
or contaminants ("Environmental Laws"), lacks any permit, license or other
approval required of it under applicable Environmental Laws is violating any

expected to, either individually or in the aggregate, have a Material Adverse
Effect.

                  (r) Each of the Company, the Subsidiaries and the Joint
Ventures has (i) good and marketable title to all of the properties and assets
described in the Prospectuses as owned by it, free and clear of all liens,
charges, encumbrances and restrictions, except such as are described in the
Prospectuses or as would not have a Material Adverse Effect, (ii) peaceful and
undisturbed possession under all leases to which any of them is a party as
lessee, (iii) all licenses, certificates, permits, authorizations, approvals,

the FCC), all self-regulatory authorities and all courts and other tribunals
(each an "Authorization") necessary to engage in the business as presently
<PAGE>

conducted by any of them in the manner described in the Prospectuses, except as
described in the Prospectuses or where failure to hold such Authorizations would
not, individually or in the aggregate, have a Material Adverse Effect and (iv)
no reason to believe that any governmental body or agency is considering
limiting, suspending or revoking any such Authorization. Except where the
failure to be in full force and effect would not have a Material Adverse Effect,
all such Authorizations are valid and in full force and effect and each of the
Company, the Subsidiaries and the Joint Ventures is in compliance with the terms
and conditions of all such Authorizations and with the rules and regulations of
the regulatory authorities having jurisdiction with respect thereto. All leases
to which the Company, the Subsidiaries and the Joint Ventures is a party are
valid and binding and no default by the Company, any Subsidiary or any Joint
Venture has occurred and is continuing thereunder and no defaults by the
landlord are existing under any such lease that could reasonably be expected to
result in a Material Adverse Effect.

                  (s) Each of the Company, the Subsidiaries and the Joint
Ventures owns, possesses or has the right to employ all patents, patent rights,
licenses (including all FCC, state, local or other jurisdictional regulatory
licenses), inventions, copyrights, know-how (including trade secrets and other
unpatented and/or unpatentable proprietary or confidential information,
software, systems or procedures), trademarks, service marks and trade names,
inventions, computer programs, technical data and information (collectively, the
"Intellectual Property") presently employed by the Company, its Subsidiaries or
the Joint Ventures in connection with the businesses now operated by it or which
are proposed to be operated by the Company, its Subsidiaries or the Joint
Ventures free and clear of and without violating any right, claimed right,
charge, encumbrance, pledge, security interest, restriction or lien of any kind
of any other person and none of the Company, any Subsidiary or any Joint Venture
has received any notice of infringement of or conflict with asserted rights of
others with respect to any of the foregoing except as could not reasonably be
expected to have a Material Adverse Effect. The use of the Intellectual Property
in connection with the business and operations of the Company, the Subsidiaries
and the Joint Ventures does not infringe on the rights of any person, except
would not have a Material Adverse Effect.

                  (t) None of the Company, any Subsidiary, any Joint Venture or
any of their respective officers, directors, partners, employees, agents or
affiliates or any other person acting on behalf of the Company, any Subsidiary
or any Joint Venture, as the case may be, has, directly or indirectly, given or
agreed to give any money, gift or similar benefit (other than legal price
concessions to customers in the ordinary course of business) to any customer,
supplier, employee or agent of a customer or supplier, official or employee of
any governmental agency (domestic or foreign), instrumentality of any government
(domestic or foreign) or any political party or candidate for office (domestic
or foreign) or other person who was, is or may be in a position to help or
hinder the business of the Company, any Subsidiary or any Joint Venture (or
assist the Company, any Subsidiary or any Joint Venture in connection with any
actual or proposed transaction) which (i) might subject the Company, any
Subsidiary or any Joint Venture, or any other individual or entity to any damage
or penalty in any civil, criminal or governmental litigation or proceeding
(domestic or foreign), (ii) if not given in the past, could reasonably be
expected to have had a Material Adverse Effect on the assets, business or
operations of the Company, any Subsidiary or any Joint Venture or (iii) if not
continued in the future, could reasonably be expected to have a Material Adverse
Effect.

                  (u) All tax returns required to be filed by the Company, each
of the Subsidiaries and each of the Joint Ventures in all jurisdictions have
been so filed. All taxes, including withholding taxes, penalties and interest,
assessments, fees and other charges due or claimed to be due from such entities
or that are due and payable have been paid, other than those being contested in
good faith and for which adequate reserves have been provided or those currently
payable without penalty or interest. There are no proposed additional tax
assessments against the Company, any Subsidiary, any Joint Venture or the assets
or property of the Company, any Subsidiary or any Joint Venture.
<PAGE>

                  (v) None of the Company, the Subsidiaries or the Joint

Prospectuses under the caption "Use of Proceeds" will not be (i) an "investment
company" or a company "controlled" by an "investment company" within the meaning
of the Investment Company Act of 1940, as amended (the "Investment Company
Act"), or (ii) a "holding company" or a "subsidiary company" or an "affiliate"
of a holding company within the meaning of the Public Utility Holding Company
Act of 1935, as amended (the "PUHC Act").

                  (w) Except as disclosed in the Prospectuses, there are no
holders of securities of the Company, the Subsidiaries or the Joint Ventures
who, by reason of the filing of the Registration Statement or consummation of
the transactions contemplated by this Agreement or the U.S. Underwriting
Agreement, have the right to request or demand that the Company, any of the
Subsidiaries or any of the Joint Ventures register any of its securities
(including, without limitation, Class A Common Stock and Class B Common Stock)
under the Act. No such rights with respect to any shares of Class A Common Stock
have been exercised as of the date hereof.

                  (x) Each of the Company, the Subsidiaries and the Joint
Ventures maintains a system of internal accounting controls sufficient to
provide reasonable assurance that: (i) transactions are executed in accordance
with management's general or specific authorizations; (ii) transactions are
recorded as necessary to permit preparation of financial statements in
conformity with generally accepted accounting principles and to maintain
accountability for assets; (iii) access to assets is permitted only in
accordance with management's general or specific authorization and (iv) the
recorded accountability for assets is compared with the existing assets at
reasonable intervals and appropriate action is taken with respect thereto.

                  (y) Each of the Company, the Subsidiaries and the Joint
Ventures maintains insurance covering its properties, operations, personnel and
businesses. Such insurance insures against such losses and risks as are adequate
in accordance with customary industry practice to protect the Company, the
Subsidiaries, the Joint Ventures and their respective businesses. None of the
Company, any Subsidiary or any Joint Venture has received notice from any
insurer or agent of such insurer that substantial capital improvements or other
expenditures will have to be made in order to continue such insurance. All such
insurance is outstanding and duly in force on the date hereof.

                  (z) None of the Company, any Subsidiary or any Joint Venture
has (i) taken, directly or indirectly, any action designed to, or that might
reasonably be expected to, cause or result in stabilization or manipulation of
the price of any security of the Company to facilitate the sale or resale of the
Class A Common Stock, (ii) since the date of the Prospectuses, (A) sold, bid
for, purchased or paid any person any compensation for soliciting purchases of
the Common Stock or (B) paid or agreed to pay to any person any compensation for

pension or benefit plan with respect to which the Company or any corporation
considered an affiliate of the Company within the meaning of Section 407(d)(7)
of ERISA (an "ERISA Affiliate") is a party in interest or disqualified person.
The execution and delivery of this Agreement and the issuance and sale of the
Shares will not involve any prohibited transaction within the meaning of Section
406 of ERISA or Section 4975 of the Internal Revenue Code of 1986, as amended.

                  (bb) None of (A) the execution, delivery and performance of
this Agreement or the U.S. Underwriting Agreement, (B) the issuance and sale of
the Shares, (C) the application of the proceeds from the issuance and sale of
the Shares or (D) the consummation of the transactions contemplated in
connection with any of the foregoing as set forth in the Prospectuses, will
violate Regulations G, T, U or X promulgated by the Board of Governors of the
Federal Reserve System or analogous foreign laws and regulations.
<PAGE>

                  (cc) Except pursuant to this Agreement, there are no
contracts, agreements or understandings between the Company, any of its
Subsidiaries or any of its Joint Ventures and any other person that would give
rise to a valid claim against the Company or any of the Managers for a brokerage
commission, finder's fee or like payment in connection with the issuance,
purchase and sale of the Common Stock.

                  (dd) The Company has filed in a timely manner each document or
report required to be filed by it pursuant to the Exchange Act and the rules and
regulations thereunder; each such document or report at the time it was filed
conformed to the requirements of the Exchange Act and the rules and regulations
thereunder; and none or such documents or reports contained an untrue statement
of any material fact or omitted to state any material fact required to be stated
therein or necessary to make the statements therein not misleading.

                  (ee) Each of the Company, the Subsidiaries and the Joint
Ventures has complied with all provisions of Section 517.075, Florida Statutes,
relating to doing business with the Government of Cuba or with any affiliate
located in Cuba.

                  (ff) Except as disclosed in the Prospectuses, there are no
business relationships or related party transactions required to be disclosed
therein pursuant to Item 404 of Regulation S-K of the Commission.

                  The Company acknowledges that the Managers and, for purposes
of the opinions to be delivered to the Managers pursuant to Section 8(e), (f)
and (g) hereof, counsel to the Company and counsel to the Managers, will rely
upon the accuracy and truth of the foregoing representations and hereby consents
to such reliance.

        7. Indemnification and Contribution. (a) The Company agrees to indemnify
and hold harmless each of you and each other Manager and each person, if any,
who controls any Manager within the meaning of Section 15 of the Act or Section
20(a) of the Exchange Act from and against any and all losses, claims, damages,
liabilities and expenses (including reasonable costs of investigation) arising
out of or based upon any untrue statement or alleged untrue statement of a
material fact contained in any International Prepricing Prospectus or in the
Registration Statement or the International Prospectus or in any amendment or
supplement thereto, or arising out of or based upon any omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, except insofar as such
losses, claims, damages, liabilities or expenses arise out of or are based upon
any untrue statement or omission or alleged untrue statement or omission which
has been made therein or omitted therefrom in reliance upon and in conformity
with the information relating to such Manager furnished in writing to the
Company by any Manager through the Lead Managers expressly for use in connection
therewith; provided, however, that the indemnification contained in this
paragraph (a) with respect to any International Prepricing Prospectus shall not
inure to the benefit of any Manager (or to the benefit of any person controlling
such Manager) on account of any such loss, claim, damage, liability or expense
arising from the sale of the Shares by such Manager to any person if a copy of
the International Prospectus shall not have been delivered or sent to such
person within the time required by the Act and the regulations thereunder, and
the untrue statement or alleged untrue statement or omission or alleged omission
of a material fact contained in such International Prepricing Prospectus was
corrected in the International Prospectus, provided that the Company has
delivered the International Prospectus to the several Managers in requisite
quantity on a timely basis to permit such delivery or sending. The foregoing
indemnity agreement shall be in addition to any liability which the Company may
otherwise have.

        (b) If any action, suit or proceeding shall be brought against any
Manager or any person controlling any Manager in respect of which indemnity may
be sought against the Company, such Manager or such controlling person shall
promptly notify the Company, and the Company shall assume the defense thereof,
<PAGE>

including the employment of counsel and payment of all fees and expenses. Such
Manager or any such controlling person shall have the right to employ separate
counsel in any such action, suit or proceeding and to participate in the defense
thereof, but the fees and expenses of such counsel shall be at the expense of
such Manager or such controlling person unless (i) the Company has agreed in
writing to pay such fees and expenses, (ii) the Company has failed to assume the
defense and employ counsel, or (iii) the named parties to any such action, suit
or proceeding (including any impleaded parties) include both such Manager or
such controlling person, and the Company and such Manager or such controlling
person shall have been advised by its counsel that representation of such
indemnified party and the Company by the same counsel would be inappropriate
under applicable standards of professional conduct (whether or not such
representation by the same counsel has been proposed) due to actual or potential
differing interests between them (in which case the Company shall not have the
right to assume the defense of such action, suit or proceeding on behalf of such
Manager or such controlling person). It is understood, however, that the Company
shall, in connection with any one such action, suit or proceeding or separate
but substantially similar or related actions, suits or proceedings in the same
jurisdiction arising out of the same general allegations or circumstances, be
liable for the reasonable fees and expenses of only one separate firm of
attorneys (in addition to any local counsel) at any time for all such Managers
and controlling persons not having actual or potential differing interests with
you or among themselves, which firm shall be designated in writing by Smith
Barney Inc., and that all such fees and expenses shall be reimbursed as they are
incurred. The Company shall not be liable for any settlement of any such action,
suit or proceeding effected without its written consent, but if settled with
such written consent, or if there be a final judgment for the plaintiff in any
such action, suit or proceeding, the Company agrees to indemnify and hold
harmless any Manager, to the extent provided in the preceding paragraph, and any
such controlling person from and against any loss, claim, damage, liability or
expense by reason of such settlement or judgment.

        (c) Each Manager agrees, severally and not jointly, to indemnify and
hold harmless the Company, its directors, its officers who sign the Registration
Statement, and any person who controls the Company within the meaning of Section
15 of the Act or Section 20(a) of the Exchange Act, to the same extent as the
foregoing indemnity from the Company to each Manager, but only with respect to
information relating to such Manager furnished in writing by or on behalf of
such Manager through the Lead Managers expressly for use in the Registration
Statement, the International Prospectus or any International Prepricing
Prospectus, or any amendment or supplement thereto. If any action, suit or
proceeding shall be brought against the Company, any of its directors, any such
officer, or any such controlling person based on the Registration Statement, the
International Prospectus or any International Prepricing Prospectus, or any
amendment or supplement thereto, and in respect of which indemnity may be sought
against any Manager pursuant to this paragraph (c), such Manager shall have the
rights and duties given to the Company by paragraph (b) above (except that if
the Company shall have assumed the defense thereof such Manager shall not be
required to do so, but may employ separate counsel therein and participate in
the defense thereof, but the fees and expenses of such counsel shall be at such
Manager's expense), and the Company, its directors, any such officer, and any
such controlling person shall have the rights and duties given to the Managers
by paragraph (b) above. The foregoing indemnity agreement shall be in addition
to any liability which the Managers may otherwise have.

        (d) If the indemnification provided for in this Section 7 is unavailable
to an indemnified party under paragraphs (a) or (c) hereof in respect of any
losses, claims, damages, liabilities or expenses referred to therein, then an
indemnifying party, in lieu of indemnifying such indemnified party, shall
contribute to the amount paid or payable by such indemnified party as a result
of such losses, claims, damages, liabilities or expenses (i) in such proportion
as is appropriate to reflect the relative benefits received by the Company on
the one hand and the Managers on the other hand from the offering of the Shares,
or (ii) if the allocation provided by clause (i) above is not permitted by
applicable law, in such proportion as is appropriate to reflect not only the
relative benefits referred to in clause (i) above but also the relative fault of
the Company on the one hand and the Managers on the other in connection with the
statements or omissions that resulted in such losses, claims, damages,
<PAGE>

liabilities or expenses, as well as any other relevant equitable considerations.
The relative benefits received by the Company on the one hand and the Managers
on the other shall be deemed to be in the same proportion as the total net
proceeds from the offering (before deducting expenses) received by the Company
bear to the total underwriting discounts and commissions received by the
Managers, in each case as set forth in the table on the cover page of the
International Prospectus. The relative fault of the Company on the one hand and
the Managers on the other hand 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 by the Company on the one hand or by the Managers on the other hand and
the parties' relative intent, knowledge, access to information and opportunity
to correct or prevent such statement or omission.

        (e) The Company and the Managers agree that it would not be just and
equitable if contribution pursuant to this Section 7 were determined by a pro
rata allocation (even if the Managers were treated as one entity for such
purpose) or by any other method of allocation that does not take account of the
equitable considerations referred to in paragraph (d) above. The amount paid or
payable by an indemnified party as a result of the losses, claims, damages,
liabilities and expenses referred to in paragraph (d) above shall be deemed to
include, subject to the limitations set forth above, any legal or other expenses
reasonably incurred by such indemnified party in connection with investigating
any claim or defending any such action, suit or proceeding. Notwithstanding the
provisions of this Section 7, no Manager shall be required to contribute any
amount in excess of the amount by which the total price of the Shares
underwritten by it and distributed to the public exceeds the amount of any
damages which such Manager has otherwise been required to pay by reason of such
untrue or alleged untrue statement or omission or alleged omission. No person
guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of
the Act) shall be entitled to contribution from any person who was not guilty of
such fraudulent misrepresentation. The Managers' obligations to contribute
pursuant to this Section 7 are several in proportion to the respective numbers
of Shares set forth opposite their names in Schedule I hereto (or such numbers
of Shares increased as set forth in Section 10 hereof) and not joint.

        (f) No indemnifying party shall, without the prior written consent of
the indemnified party, effect any settlement of any pending or threatened
action, suit or proceeding in respect of which any indemnified party is or could
have been a party and indemnity could have been sought hereunder by such
indemnified party, unless such settlement includes an unconditional release of
such indemnified party from all liability on claims that are the subject matter
of such action, suit or proceeding.

        (g) Any losses, claims, damages, liabilities or expenses for which an
indemnified party is entitled to indemnification or contribution under this
Section 7 shall be paid by the indemnifying party to the indemnified party as
such losses, claims, damages, liabilities or expenses are incurred. The
indemnity and contribution agreements contained in this Section 7 and the
representations and warranties of the Company set forth in this Agreement shall
remain operative and in full force and effect, regardless of (i) any
investigation made by or on behalf of any Manager or any person controlling any
Manager, the Company, its directors or officers, or any person controlling the
Company, (ii) acceptance of any Shares and payment therefor hereunder, and (iii)
any termination of this Agreement. A successor to any Manager or any person
controlling any Manager, or to the Company, its directors or officers, or any
person controlling the Company, shall be entitled to the benefits of the
indemnity, contribution, and reimbursement agreements contained in this Section
7.

post-effective amendment shall have become effective not later than 5:30 P.M.,

of any addition to or change in the Prospectuses in order to state a material
fact required by the Act or any other law to be stated therein or necessary in

                     10.   Effective  Date of  Agreement.  This  Agreement  
shall  become  effective:  (i) upon the
execution and delivery hereof by the parties hereto; or (ii) if, at the time
this Agreement is executed and delivered, it is necessary for the Registration
Statement or a post-effective amendment thereto to be declared effective before
the offering of the Shares may commence, when notification of the effectiveness

Lead Managers for the several Managers, by notifying the Company.

             If any one or more of the Managers shall fail or refuse to purchase

and the aggregate number of Shares which such defaulting Manager or Managers are
obligated but fail or refuse to purchase is not more than one-tenth of the
aggregate number of Shares which the Managers are obligated to purchase on the
Closing Date, each non-defaulting Manager shall be obligated, severally, in the
proportion which the number of Shares set forth opposite its name in Schedule I
hereto bears to the aggregate number of Shares set forth opposite the names of
all non-defaulting Managers or in such other proportion as you may specify in
accordance with Section 20 of the Master Agreement Among Underwriters of Smith
Barney Inc., to purchase the Shares which such defaulting Manager or Managers
are obligated, but fail or refuse, to purchase. If any one or more of the
Managers shall fail or refuse to purchase Shares which it or they are obligated
to purchase on the Closing Date and the aggregate number of Shares with respect
to which such default occurs is more than one-tenth of the aggregate number of
Shares which the Managers are obligated to purchase on the Closing Date and
arrangements satisfactory to you and the Company for the purchase of such Shares
<PAGE>

by one or more non-defaulting Managers or other party or parties approved by you

will terminate without liability on the part of any non-defaulting Manager or
the Company. In any such case which does not result in termination of this
Agreement, either you or the Company shall have the right to postpone the
Closing Date, but in no event for longer than seven days, in order that the
required changes, if any, in the Registration Statement and the Prospectus or
any other documents or arrangements may be effected. Any action taken under this
paragraph shall not relieve any defaulting Manager from liability in respect of
any such default of any such Manager under this Agreement. The term "Manager" as
used in this Agreement includes, for all purposes of this Agreement, any party
not listed in Schedule I hereto who, with your approval and the approval of the
Company, purchases Shares which a defaulting Manager is obligated, but fails or
refuses, to purchase.

               Any notice under this Section 10 may be given by telegram,
telecopy or telephone but shall be subsequently confirmed by letter.

               11. Termination of Agreement. This Agreement shall be subject to
termination in your absolute discretion, without liability on the part of any
Manager to the Company, by notice to the Company, if prior to the Closing Date,
(i) trading in securities generally on the New York Stock Exchange, the American
Stock Exchange or the Nasdaq National Market shall have been suspended or
materially limited, (ii) a general moratorium on commercial banking activities
in New York or Philadelphia shall have been declared by either federal or state
authorities, or (iii) there shall have occurred any outbreak or escalation of
hostilities or other U.S. or domestic calamity, crisis or change in political,
financial or economic conditions, the effect of which on the financial markets
of the United States is such as to make it, in your judgment, impracticable or
inadvisable to commence or continue the offering of the Shares at the offering
price to the public set forth on the cover page of the International Prospectus
or to enforce contracts for the resale of the Shares by the Managers. Notice of
such termination may be given to the Company by telegram, telecopy or telephone
and shall be subsequently confirmed by letter.

               12. Information Furnished by the Managers. The statements set
forth in the last paragraph on the cover page, the stabilization legend on the
inside cover page, and the statements in the first, third, seventh, eighth,
ninth and fifteenth paragraphs under the caption "Underwriting" in any
International Prepricing Prospectus and in the International Prospectus,

through you as such information is referred to in Sections 6(b) and 7 hereof.

               13. Miscellaneous. Except as otherwise provided in Sections 5, 10
and 11 hereof, notice given pursuant to any provision of this Agreement shall be
in writing and shall be delivered (i) if to the Company, at the office of the
Company at Hyperion Telecommunications, Inc., Main at Water Street, Coudersport,

several Managers, the Company, its directors and officers, and the other
controlling persons referred to in Section 7 hereof and their respective
successors and assigns, to the extent provided herein, and no other person shall
acquire or have any right under or by virtue of this Agreement. Neither the term
"successor" nor the term "successors and assigns" as used in this Agreement
shall include a purchaser from any Manager of any of the Shares in his status as
such purchaser.

               14. Applicable Law; Counterparts. This Agreement shall be
governed by and construed in accordance with the laws of the State of New York
applicable to contracts made and to be performed within the State of New York.

               This Agreement may be signed in various counterparts which

                      FORM OF OPINION OF BUCHANAN INGERSOLL

                  1. Each of the Company and the Subsidiaries is duly organized
and validly existing as a corporation or a limited liability company in good
standing under the laws of its jurisdiction of formation, as applicable, and has
all requisite corporate power and authority to carry on its business as it is
being conducted and as described in the Registration Statement and the
Prospectuses and to own, lease and operate its properties, and is duly qualified
and in good standing as a foreign corporation or limited liability company, as
applicable, authorized to do business in each jurisdiction in which the nature
of its business or its ownership or leasing of property requires such
qualification, except where the failure to be so qualified would not, singly or
in the aggregate, have a material adverse effect on the business, financial
condition or results of operations of the Company and the Subsidiaries, taken as
a whole (a "Material Adverse Effect").

                  2. Each of the Joint Ventures has been duly incorporated or
formed as a corporation, general partnership, limited partnership or limited
liability company under the laws of its jurisdiction of incorporation or
formation, as applicable, and has all requisite power and authority to own,
lease, and operate its properties and to conduct its business as described in
the Prospectuses, and is duly qualified to transact business as a foreign
corporation, general partnership, limited partnership or limited liability
company, as applicable, in each jurisdiction in which the character of the
business being conducted by it or the location of the property owned by it makes
such qualification necessary, except where the failure to so qualify, singly or
in the aggregate, would not have a Material Adverse Effect. Each Joint Venture
that is a corporation, limited partnership or limited liability company is
validly existing and is in good standing under the laws of its jurisdiction of
incorporation or formation, as applicable.

                  3. All of the outstanding shares of capital stock of the

matters to the description thereof contained in the Prospectuses under the
caption "Description of Capital Stock."

                  4. All the shares of capital stock of the Company outstanding
prior to the issuance of the Shares to be issued and sold by the Company
pursuant to the Underwriting Agreements have been duly authorized and validly

and the International Underwriting Agreement have been duly authorized and when

therefor in accordance with the terms of the U.S. Underwriting Agreement and the
International Underwriting Agreement, will be validly issued, fully paid and
nonassessable and free of any (A) preemptive rights or (B) to the best knowledge
of such counsel after reasonable inquiry, similar rights that entitle or will
entitle any person to acquire any shares of Class A Common Stock upon the
issuance thereof by the Company.

                  6. The Adelphia New Shares (as defined in the Prospectuses)
have been duly authorized and when issued and delivered to the Parent against
payment therefor in accordance with the terms of the Adelphia Share Purchase
Agreement or the Adelphia Note Contribution Agreement, as the case may be, will
be validly issued, fully paid and nonassessable and free of (A) preemptive
rights or (B) to the best knowledge of such counsel after reasonable inquiry,
<PAGE>

similar rights that entitle or will entitle any person to acquire any shares of
Class A Common Stock upon the issuance thereof by the Company.

                  7. The Additional MCI Warrants (as defined in the
Prospectuses) have been duly authorized and, when executed and delivered
pursuant to the terms of the Warrant Agreement (the "MCI Warrant Agreement"),
dated June 13, 1997, between the Company and MCImetro Access Transmission
Services, Inc. ("MCI"), will be valid and binding obligations of the Company,
enforceable against the Company in accordance with their terms, except as
enforcement may be limited by applicable bankruptcy, insolvency, reorganization,
moratorium and other similar laws affecting the enforceability of creditors'
rights generally and by general principles of equity (whether arising under a
proceeding at law or in equity).

                  8. The maximum number of Shares issuable upon exercise of the
Additional MCI Warrants has been duly authorized and reserved for issuance by
the Company at the time and in the manner required by the MCI Warrant Agreement

Additional MCI Warrants and the MCI Warrant Agreement, such Shares will be
validly issued, fully paid and nonassessable.

                  9. Upon due issuance of the Additional MCI Warrants, the
Company will have satisfied its obligation to issue "Additional Initial
Warrants" (as such term is defined in the MCI Warrant Agreement) under Section

                  10. The Adelphia Warrant (as defined in the Prospectuses) has
been duly authorized and, when executed and delivered pursuant to the terms of
the MCI Agreement, will be valid and binding obligations of the Company,

                  12. The form of certificates for the Underwritten Shares and
the Adelphia New Shares conforms to the requirements of the Nasdaq National
Market and the Delaware General Corporation Law.

                  13. The Registration Statement and all post-effective
amendments, if any, have become effective under the Act and, to the best
knowledge of such counsel after reasonable inquiry, no stop order suspending the
effectiveness of the Registration Statement has been issued and no proceedings
for that purpose are pending before or contemplated by the Commission; and any
required filing of the Prospectuses pursuant to Rule 424(b) has been made in
accordance with Rule 424(b).

                  14. The Company has the corporate power and authority to enter
into the U.S. Underwriting Agreement and the International Underwriting
Agreement and to issue, sell and deliver the Shares to be sold by it to the U.S.
Underwriters and Managers as provided therein, and each of the U.S. Underwriting
Agreement and the International Underwriting Agreement have been duly
authorized, executed and delivered by the Company and is a legal, valid and
binding agreement of the Company, enforceable against the Company in accordance
with its terms, except that (A) enforceability may be limited by bankruptcy,
insolvency, reorganization, moratorium or other similar laws not or hereafter in
effect relating to creditors' rights generally, (B) the remedy of specific
<PAGE>

performance and other forms of equitable relief may be subject to certain
equitable defenses and to the discretion of the court before which the
proceedings may be brought and (C) rights to indemnity and contribution
thereunder may be limited by Federal or state securities laws or the public
policy underlying such laws.

                  15. All of the Joint Venture's limited partnership and limited
liability company interests owned by each Subsidiary have been duly authorized
and validly issued and, except for matters referenced by the Prospectuses, all
of the partnership and limited liability company interests owned in the Joint
Ventures which are owned of record by each respective Subsidiary are, to the
best of our knowledge, owned free and clear of any security interest, lien or
other encumbrance.

                  16. All of the outstanding capital stock of each Subsidiary is
owned by the Company, free and clear of any security interest, claim, lien,
limitation on voting rights or encumbrance. There are not, to our knowledge,
other than as set forth in the Prospectuses, currently, and will not be

instruments convertible into or exchangeable for, any capital stock or other
equity interest of the Company or any Subsidiary.

supplements or amendments thereto (except for the financial statements,
schedules, and notes thereto and other financial and statistical data included
therein, as to which such counsel need not express any opinion) comply as to
form in all material respects with the requirements of the Act.

                  18. Neither the issuance, sale or delivery of the Underwritten
Shares, nor the execution, delivery or performance of the U.S. Underwriting
Agreement or the International Underwriting Agreement, or compliance by the
Company with all provisions of the U.S. Agreement and the International
Underwriting Agreement, nor consummation by the Company of the transactions
contemplated in the U.S. Underwriting Agreement or by the International
Underwriting Agreement violates, conflicts with or constitutes a breach of any
of the terms or provisions of, or a default under (or an event that with notice
or the lapse of time, or both, would constitute a default), or require consent
under, or result in the imposition of a lien or encumbrance on any properties of
the Company or any Subsidiary, or an acceleration of any indebtedness of the
Company or any Subsidiary pursuant to, (i) the charter or bylaws of the Company
or any Subsidiary, (ii) any bond, debenture, note, indenture, mortgage, deed of
trust or other agreement or instrument to which the Company or any Subsidiary is

counsel as material (assuming all of such agreements are governed by
Pennsylvania law), (iii) any local, state or Federal law, statute, ordinance,
requirement, administrative statute, rule or regulation applicable to the
Company or any Subsidiary or its assets or properties (except with respect to
the matters set forth in the opinion of Swidler & Berlin, as to which no opinion
need be expressed) or (iv) any judgment, order or decree of any court or
governmental agency or authority having jurisdiction over the Company or any
Subsidiary or its assets or properties known to such counsel, except in the case
of clauses (ii), (iii) and (iv) for such violations, conflicts, breaches,
defaults, consents, impositions of liens or accelerations that (x) would not,
singly or in the aggregate, have a Material Adverse Effect or (y) are disclosed
in the Prospectuses. Assuming compliance with applicable state securities and
Blue Sky laws, as to which such counsel need express no opinion, and except for
the filing of a registration statement under the Act, no consent, approval,
authorization or order of, or filing, registration, qualification, license or
permit of or with, any court or governmental agency, body or administrative
agency is required for (1) the execution, delivery and performance by the
Company of the International Underwriting Agreement and the International
Underwriting Agreement, (2) the issuance and sale of the Shares or (3)
consummation by the Company, the Subsidiaries and the Joint Ventures of the
transactions described in the Prospectuses, except such as have been obtained
and made or have been disclosed in the Prospectuses, and except where the
failure to obtain such consents or waivers would not, singly or in the
<PAGE>

aggregate, have a Material Adverse Effect. To the best of such counsel's
knowledge, no consents or waivers from any other person are required for the
execution, delivery and performance by the Company of the International
Underwriting Agreement and the International Underwriting Agreement or the
issuance and sale of the Underwritten Shares, other than such consents and
waivers as have been obtained.

                  19. None of the Company, its Subsidiaries or the Joint
Ventures is (i) an "investment company" or a company "controlled" by an
"investment company" within the meaning of the Investment Company Act of 1940,
as amended, or (ii) a "holding company" or a "subsidiary company" or an
"affiliate" of a holding company within the meaning of the Public Utility
Holding Company Act of 1935, as amended.

                  20. Except as set forth in the Prospectuses, there are no
holders of securities of the Company who, by reason of the execution by the
Company of the International Underwriting Agreement or the International
Underwriting Agreement or the consummation by the Company of the transactions
contemplated thereby, have the right to request or demand that the Company
register under the Act securities held by them.

                  21. None of (A) the execution, delivery and performance of the
International Underwriting Agreement or the U.S. Underwriting Agreement, (B) the
issuance and sale of the Shares and the application of the proceeds from the
issuance and sale of the Shares or (C) the consummation of the transactions
contemplated in connection with any of the foregoing as set forth in the
Prospectuses, will violate Regulations G, T, U or X promulgated by the Board of
Governors of the Federal Reserve System.

                  22. To the knowledge of such counsel, there is (i) no action,
suit, investigation or proceeding before or by any court, arbitrator or
governmental agency, body or official, domestic or foreign, now pending, or
threatened or contemplated to which any of the Company or any Subsidiary is or
may be a party or to which the business or property of any of the Company or any
Subsidiary is or may be subject, (ii) no statute, rule, regulation or order that
has been enacted, adopted or issued by any governmental agency, or (iii) no
injunction, restraining order or order of any nature by a federal or state court
of competent jurisdiction to which any of the Company or any Subsidiary is or
may be subject has been issued that, in the case of clauses (i), (ii) and (iii)
above, (x) is required to be disclosed in the Prospectuses and that is not so
disclosed and, (y) could reasonably be expected to have, either individually or
in the aggregate, a Material Adverse Effect, it being understood that for
purposes of this opinion, such counsel need express no opinion with respect to
(i) actions, suits investigation or proceedings before the FCC or any similar
state regulatory commission or body, (ii) statutes, rules, regulations or orders
by any FCC or any similar state regulatory commission or (iii) injunctions,

                  Although we have not undertaken, except as otherwise indicated
in our opinion, to determine independently, and do not assume any responsibility
for, the accuracy, completeness or fairness of the statements in the
Registration Statement, we have participated in the preparation of the
Registration Statement and the Prospectuses, including general review and
discussion of the contents thereof but have made no independent check or
verification thereof, and no facts have come to our attention that would lead us
to believe that the Registration Statement at the time the Registration
Statement became effective, or the Prospectuses, as of their respective dates
and as of the Closing Date, contained an untrue statement of a material fact or
omitted to state a material fact required to be stated in the Prospectuses or
necessary to make the statements therein, in the light of the circumstances
under which they were made, not misleading or that any amendment or supplement
to the Prospectuses, as of their respective dates, and as of the Closing Date,
contained any untrue statement of a material fact or omitted to state a material
fact required to be stated in the Prospectuses or necessary in order to make the
statements in the Prospectuses, in the light of the circumstances under which
they were made, not misleading (it being understood that such counsel need
express no opinion with respect to the financial statements, schedules, pro

included in the Registration Statement and the Prospectuses.

Warrant Shares shall be extended through, the date five Business Days after the
date on which a final ruling is made with respect to the filing(s) requesting

with, the Holder in making such filings required to be made by the Holder, and

         2.        Exercise of Warrant.

                        (a) This Warrant may be exercised, in whole at any time
         or in part from time to time, during the Exercise Period, by the Holder
         by the surrender of this Warrant (with the subscription duly executed)
         at the address set forth in paragraph 11(a) hereof, together with
         proper payment of the Exercise Price. Payment for the Warrant Shares to
         be purchased shall be made by wire transfer or certified or official
         bank check payable to the order of the Company. If this Warrant is
         exercised in part, this Warrant must be exercised for a whole number of
         shares of the Class A Common Stock, and the Holder is entitled to
         receive a new Warrant covering the number of Warrant Shares in respect
         of which this Warrant has not been exercised. Upon such surrender of
         this Warrant, the Company will issue a certificate or certificates in
         the name of the Holder for the number of shares of the Class A Common
         Stock to which the Holder shall be entitled. The Company shall not be
         required to issue a fractional share of Class A Common Stock upon any
         exercise of this Warrant, but the Company shall pay an amount in cash
         equal to the Current Market Price for one Warrant Share on the date the
         Warrant is exercised, multiplied by the fraction of a Warrant Share
         that would be issuable on the exercise of this Warrant.

                         (b) In the event any Holder elects upon exercise to
         surrender this Warrant for payment of the applicable Exercise Price for
         the shares being purchased, this Warrant shall be surrendered and
         canceled. To the extent any Holder elects to pay all or part of the
         Exercise Price by surrendering this Warrant to the Company, the number
         of purchasable shares under this Warrant required to be surrendered as
         payment for the Exercise Price (the "Warrant Consideration Amount")
<PAGE>

         shall be equal to that number obtained by dividing (i) that amount of
         the aggregate Exercise Price that any Holder elects by written notice
         to the Company to pay by the application of this Warrant (such notice
         setting forth, in addition, the required reduction in the number of
         shares purchasable by this Warrant as calculated and shown in
         sufficient detail in accordance with the immediately succeeding
         clause), by (ii) the difference obtained by subtracting (A) the
         Exercise Price per share on the date of exercise from (B) the Current
         Market Price of the Warrant Shares on the date of exercise.

                       (c)  In the event of any exercise of the rights
         represented by this Warrant, (i) certificates for the shares of Warrant
         Shares so purchased shall be dated the date of such exercise and
         delivered to the Holder hereof within a reasonable time, not exceeding
         five Business Days after such exercise, and the Holder hereof shall be
         deemed for all purposes to be the Holder of the shares of Warrant
         Shares so purchased as of the date of such exercise, and (ii) unless
         this Warrant has expired, a new Warrant representing the number of
         shares equal to (A) the number of shares purchasable under this Warrant
         less (B) the sum of (1) the number of shares of Warrant Shares
         purchased upon exercise and (2) the Warrant Consideration Amount, if
         any, shall be issued to the Holder hereof within such time.

         3. Certain Adjustments. The Exercise Price and the kind and number of
shares of Class A Common Stock issuable upon exercise of this Warrant shall be
subject to adjustment as set forth below in this paragraph 3. The Company shall
give the registered Holder notice of any event described below which requires an
adjustment pursuant to this paragraph 3 in accordance with the provisions of
paragraph 4.

                        (a) Stock Dividends, Subdivisions and Combinations.  If 
at any time the Company shall:

                           (i)       fix a record date for the purpose of
                  determining the holders of its Common Stock entitled to
                  receive a dividend payable in, or other distribution of,
                  Additional Shares of Common Stock;

                           (ii)      subdivide its outstanding shares of Common 
                  Stock into a larger number of shares of Common Stock;

                           (iii)     combine its outstanding shares of Common 
                  Stock into a smaller number of shares of Common Stock; or

                           (iv)      issue any shares of its capital stock or
                  other Securities by reclassification of the Common Stock
                  (other than pursuant to paragraph 3(c) below); then the
                  Exercise Price shall be proportionately decreased in the case
                  of such a dividend or distribution of Additional Shares of
                  Common Stock or such a subdivision, or proportionately
                  increased in the case of such a combination, or the kind of
                  capital stock or other securities of the Company which may be
                  purchased shall be adjusted in the case of such a
                  reclassification of the Common Stock, each on the record date
<PAGE>
              
                  for such dividend or distribution or effective date of such
                  subdivision, combination or reclassification, as the case may
                  be, such that the Holder shall be entitled to receive, upon
                  exercise of this Warrant, the aggregate number and kind of
                  shares of Common Stock which, if this Warrant had been fully
                  exercised immediately prior to such date, it would have owned
                  upon such exercise and been entitled to receive by virtue of
                  such dividend, distribution, subdivision, combination or
                  reclassification.

                        (b) Certain Other Dividends and Distributions. If at any
         time the Company shall fix a record date for the purpose of determining
         the holders of its Common Stock entitled to receive any dividend or
         other distribution (including any such distribution made in connection
         with a consolidation or merger, but excluding any distribution referred
         to in subparagraph (a) above) of:

                            (i)      any evidences of indebtedness, any shares
                  of its capital stock (including Convertible Securities but
                  excluding Common Stock) or any other securities or property of
                  any nature whatsoever (including cash but excluding normal
                  cash dividends or cash distributions permitted under
                  applicable law so long as in each case such cash is payable
                  solely out of earnings or earned surplus of the Company); or

                            (ii)     any warrants or other rights to subscribe
                  for or purchase any evidences of its indebtedness, any shares
                  of its capital stock (including Convertible Securities) or any
                  other of its securities or its property of any nature
                  whatsoever;

                  then the Exercise Price shall be adjusted to equal the
                  Exercise Price in effect prior to such distribution or
                  dividend multiplied by a fraction, (A) the numerator of which
                  shall be (1) the Current Market Price per share of the Class A
                  Common Stock on such record date minus (2) the amount
                  allocable to one share of Class A Common Stock of the fair
                  value of any and all such evidences of indebtedness, shares of
                  stock, other securities or property or warrants or other
                  subscription or purchase rights so distributable (as
                  determined in good faith by the Board of Directors of the
                  Company and, unless waived by the Holder, supported by an
                  opinion from an investment banking firm of nationally
                  recognized standing approved by the Holder, which approval
                  shall not be unreasonably withheld), and (B) the denominator
                  of which shall be such Current Market Price per share of Class
                  A Common Stock on such record date. Such adjustments shall be
                  made whenever such a record date is fixed. A reclassification
                  of the Common Stock (other than a change in par value, or from
                  par value to no par value or from no par value to par value)
                  into shares of Common Stock and shares of any other class of
                  stock shall be deemed a distribution by the Company to the
                  holders of its Common Stock of such shares of such other class
                  of stock within the meaning of this subparagraph (b) and, if
                  the outstanding shares of Common Stock shall be changed into a
                  larger or smaller number of shares of Common Stock as a part
                  of such reclassification, such change shall be deemed a
                  subdivision or combination, as the case may be, of the
<PAGE>

                  outstanding shares of Common Stock within the meaning of
                  subparagraph (a). The Company shall give to the Holder of this
                  Warrant not less than twenty (20) days' prior notice of any
                  record date referred to in this subparagraph (b) in accordance
                  with the provisions of paragraph 4.

                      (c)   Adjustments for Consolidation, Merger, Sale of 
 Assets, Reorganization, etc.

                         (i)        In case the Company after the date hereof
                  (A) shall consolidate with or merge into any other Person and
                  shall not be the continuing or surviving corporation of such
                  consolidation or merger, or (B) shall permit any other Person
                  to consolidate with or merge into the Company and the Company
                  shall be the continuing or surviving Person but, in connection
                  with such consolidation or merger, the Class A Common Stock
                  shall be changed into or exchanged for stock or other
                  securities of any other Person or cash or any other property,
                  or (C) shall transfer all or substantially all of its
                  properties or assets to any other Person or (D) shall effect a
                  capital reorganization or reclassification of the Class A
                  Common Stock (other than a capital reorganization or
                  reclassification for which adjustment in the Exercise Price is
                  provided in subparagraph 3(a) or subparagraph 3(b)), then, and
                  in the case of each such transaction, proper provision shall
                  be made so that, upon the basis and the terms and in the
                  manner provided in this Warrant, the Holder of this Warrant
                  shall be entitled (x) upon the exercise hereof at any time
                  after the consummation of such transaction, to the extent this
                  Warrant is not exercised prior to such transaction, or is
                  redeemed in connection with such transaction, to receive at
                  the Exercise Price in effect at the time immediately prior to
                  the consummation of such transaction in lieu of the Class A
                  Common Stock issuable upon such exercise of this Warrant prior
                  to such transaction the stock and other securities, cash and
                  property to which such Holder would have been entitled upon
                  the consummation of such transaction if such Holder had
                  exercised the rights represented by this Warrant immediately
                  prior thereto, subject to adjustments (subsequent to such
                  corporate action) as nearly equivalent as possible to the
                  adjustments provided for in this paragraph 3 or (y) to sell
                  this Warrant (or, at such Holder's election, a portion
                  thereof) to the Person continuing after or surviving such
                  event specified in clauses (a) through (d) above, or to the
                  Company (if the Company is the continuing or surviving Person)
                  at a sales price equal to the amount of cash, property and/or
                  the number of shares of Common Stock or other securities to
                  which a holder of the number of shares of Class A Common Stock
                  which would otherwise have been delivered upon the exercise of
                  this Warrant or the portion hereof redeemed would have been
                  entitled upon the effective date or closing of any such event
                  specified in clauses (a) through (d) above (the "Event
                  Consideration"), less the amount or portion of such Event
                  Consideration having a fair value equal to the aggregate
                  Exercise Price applicable to this Warrant or the portion
                  hereof so sold.

                           (ii) Notwithstanding anything contained in this
                  Warrant to the contrary, the Company will not effect any of
                  the transactions described in clauses (a) through (d) of the
                  above subparagraph (i) unless, prior to the consummation
<PAGE>

                  thereof, the surviving Person (if other than the Company) in
                  any merger or consolidation described in such clauses, each
                  Person which is to acquire the Company's assets in any
                  transaction described in clause (c) above, and each Person
                  (other than the Company) which may be required to deliver any
                  stock, securities, cash or property upon the exercise of this
                  Warrant as provided herein, shall assume, by written
                  instrument delivered to, and reasonably satisfactory to, the
                  Holder of this Warrant, (A) the obligations of the Company
                  under this Warrant (and if the Company shall survive the
                  consummation of such transaction, such assumption shall be in
                  addition to, and shall not release the Company from, any
                  continuing obligations of the Company under this Warrant) and
                  (B) the obligation to deliver to such Holder such shares of
                  stock, securities, cash or, property as, in accordance with
                  the foregoing provisions of this paragraph (c), such Holder
                  shall be entitled to receive, and such Person shall hive
                  similarly delivered to such Holder an opinion of counsel for
                  such Person, which counsel shall be reasonably satisfactory to
                  such Holder, stating that this Warrant shall thereafter
                  continue in full force and effect and the terms hereof
                  (including, without limitation, all of the provisions of this
                  paragraph 3) shall be applicable to the stock, securities,
                  cash or property which such Person may be required to deliver
                  upon any exercise of this Warrant or the exercise of any
                  rights pursuant hereto.

                            (iii)    In case any of the transactions described
                  in clauses (A) through (D) of subparagraph (i) shall be
                  proposed to be effected (any such transaction a "Merger
                  Triggering Event"), the Holder of this Warrant may, and the
                  Company agrees that as a condition to the consummation of any
                  such Merger Triggering Event, the Company shall secure the
                  right of such Holder to, sell this Warrant (or, at such
                  Holder's election, a portion thereof) to the Person continuing
                  after or surviving such Merger Triggering Event, or the
                  Company (if the Company is the continuing or surviving
                  Person), simultaneously with, the effective date or closing of
                  such Merger Triggering Event, at a sale price equal to the
                  amount of cash, property and/or the number of shares of Common
                  Stock or other securities to which a holder of the number of
                  shares of Class A Common Stock which would otherwise have been
                  deliverable upon the exercise of this Warrant or the portion
                  hereof redeemed would have been entitled upon the effective
                  date or closing of such Merger Triggering Event (the
                  "Transaction Consideration"), less the amount or portion of
                  such Transaction Consideration having a fair value equal to
                  the aggregate Exercise Price applicable to this Warrant or the
                  portion hereof so sold. In the event that the Holder of this
                  Warrant exercises its rights under this subparagraph (iii) to
                  sell this Warrant (or a portion thereof) simultaneously with
                  the effective date or closing of any such Merger Triggering
                  Event, the Company shall not effect any such Merger Triggering
                  Event unless upon or prior to the consummation thereof such
                  amounts of cash, property, Common Stock, or other securities
                  are delivered to the Holder of this Warrant. Not less than
                  twenty (20) days' prior notice of any Merger Triggering Event
                  shall be given to the Holder of this Warrant in accordance
                  with paragraph 4.
<PAGE>

                       (d)  Adjustment of Number of Warrant Shares. Upon each
         adjustment of the Exercise Price, as the case may be, pursuant to
         subparagraph (a) or (b) of this paragraph 3, this Warrant shall be
         deemed to evidence the right to purchase, at the adjusted Exercise
         Price, that number of shares of Class A Common Stock obtained by
         multiplying the number of shares of Class A Common Stock covered by
         this Warrant immediately prior to such adjustment by the Exercise Price
         in effect prior to such adjustment and dividing the product so obtained
         by the Exercise Price in effect after such adjustment. If the Company
         shall be in default under any provision of this Warrant so that shares
         issued at the Exercise Price adjusted in accordance with the terms of
         this Warrant would not be validly issued, the adjustment of number of
         shares provided for in the foregoing sentence shall nonetheless be
         made, and the Holder of this Warrant shall be entitled to purchase such
         greater number of shares at the lowest price at which such shares may
         then be validly issued under applicable law. Such exercise shall not
         constitute a waiver of any claim arising against the Company by reason
         of its default under this Warrant.

                       (e)  When Adjustments to Be Made. No adjustment in the
         Exercise Price shall be required by this paragraph 3 if such adjustment
         either by itself or with other adjustments not previously made would
         require an increase or decrease of less than 1% in such price. Any
         adjustment representing a change of less than such minimum amount which
         is postponed shall be carried forward and made as soon as such
         adjustment, together with other adjustments required by this paragraph
         3 and not previously made, would result in a minimum adjustment.
         Notwithstanding the foregoing, any adjustment carried forward shall be
         made no later than ten Business Days prior to the Termination Date. All
         calculations under this subparagraph (h) shall be made to the nearest
         cent. For the purpose of any adjustment, any specified event shall be
         deemed to have occurred at the close of business on the date of its
         occurrence.

                       (f)  Fractional Interests. In computing adjustments under
         this paragraph 3, fractional interests in Common Stock shall be taken
         into account to the nearest whole share.

                       (g)  When Adjustments Not Required. If the Company shall
         fix a record date for the purpose of determining the holders of its
         Common Stock entitled to receive a dividend or distribution and shall,
         thereafter and before the distribution to stockholders thereof, legally
         abandon its plan to pay or deliver such dividend or distribution, then
         thereafter no adjustment shall be required by reason of the taking of
         such record and any such adjustment previously made in respect thereof
         shall be rescinded and annulled.

                       (h)  Certain Limitations. Subject to the provisions of
         paragraph 6, there shall be no adjustment of the Exercise Price
         hereunder to the extent that such adjustment would cause the Exercise
         Price to be less than the par value per share of the Common Stock,
         which par value shall not at any time while this Warrant is outstanding
         exceed $.01.

                       (i)  Other Action Affecting Common Stock. In case after
         the date hereof the Company shall take any action affecting its Common
         Stock, other than an action described in any of the foregoing
         subparagraphs (a) through (k) of this paragraph 3, inclusive, and the
         failure to make any adjustment would not fairly protect the purchase
<PAGE>

         rights represented by this Warrant in accordance with the essential
         intent and principle of this paragraph 3, then the Exercise Price
         and/or the number of Warrant Shares shall be adjusted in such manner
         and at such time as the Board of Directors of the Company may in good
         faith determine to be equitable in the circumstances.

         4.        Notices.

                  (a) Notices of Adjustments. Whenever the Exercise Price or the
         number of Warrant Shares shall be adjusted pursuant to paragraph 3, the
         Company shall forthwith deliver to the Holder a certificate prepared by
         the Company, setting forth, in reasonable detail, the event requiring
         the adjustment and the method by which such adjustment was calculated
         (including a description of the basis on which the Board of Directors
         of the Company determined the fair value of any evidences of
         indebtedness, shares of stock, other securities or property or warrants
         or other subscription or purchase rights), specifying the number of
         Warrant Shares then issuable hereunder, the Exercise Price after giving
         effect to such adjustment and (to the extent applicable) describing the
         number and kind of any other shares of stock for which the Warrant is
         exercisable. In the event that the Holder shall disagree with any such
         adjustment or with the terms of any new agreement to be entered into
         pursuant to paragraph 3(c), it shall notify the Company thereof and any
         disagreement shall be resolved by an investment banking firm of
         nationally recognized standing mutually agreeable to the Company and
         the Holder, or if the Company and the Holder are unable to agree upon
         an investment banking firm, an investment banking firm selected by an
         investment banking firm chosen by the Company and an investment banking
         firm chosen by the Holder.

                  (b)       Notices of Corporate Action.  In the event of any 
         of the following:

                       (i)           any taking by the Company of a record of
                  the holders of any class of securities for the purpose of
                  determining the holders thereof who are entitled to receive
                  any dividend or other distribution, or any right to subscribe
                  for, purchase or otherwise acquire any shares of stock of any
                  class or any other securities or property, or to receive any
                  other right, which dividend, distribution or other right
                  affects the rights of the Holder, or

                       (ii)          any capital reorganization of the Company,
                  any reclassification or recapitalization of the capital stock
                  of the Company or any consolidation or merger involving the
                  Company and any other party or any transfer of all or
                  substantially all the assets of the Company to any other
                  party, or

                       (iii)         any voluntary or involuntary dissolution, 
                  liquidation or winding-up of the Company;

The Company will mail to the Holder a notice specifying (A) the date or expected
date on which any such record is to be taken for the purpose of such dividend,
distribution or right and the amount and character of any such dividend,
distribution or right and (B) the date or expected date on which any such
<PAGE>

reorganization, reclassification, recapitalization, consolidation, merger,
transfer, dissolution, liquidation or winding-up is to take place and the time,
if any such time is to be fixed, as of which the holders of record of Class A
Common Stock (or other securities) shall be entitled to exchange their shares of
Class A Common Stock (or other securities) for the securities or other property
deliverable upon such reorganization, reclassification, recapitalization,
consolidation, merger, transfer, dissolution, liquidation or winding-up. Such
notice shall be mailed at least twenty (20) days prior to the date herein
specified, in the case of any date referred to in the foregoing subdivision (A),
and at least twenty (20) days prior to the date therein specified, in the case
of the date referred to in the foregoing subdivision (B).

         5. Reservation of Warrant Shares. The Company agrees that, upon
commencement of the Exercise Period and at all times prior to the Termination
Date, the Company will at all times have authorized and in reserve, and will
keep available, solely for issuance or delivery upon the exercise of this
Warrant, the shares of the Class A Common Stock and other securities and
properties as from time to time shall be receivable upon the exercise of this
Warrant, free and clear of all restrictions on sale or transfer and free and
clear of all preemptive rights. The Company shall not by any action, including,
without limitation, amending its certificate of incorporation or through any
reorganization, transfer of assets, consolidation, merger, dissolution, issue or
sale of securities or any other voluntary action, avoid or seek to avoid the
observance or performance of any of the terms of this Warrant, but will at all
times in good faith assist in the carrying out of all such terms and in the
taking of all such actions as may be necessary or appropriate to protect the
rights of the Holders hereof against impairment. Without limiting the generality
of the foregoing, the Company will (a) not increase the par value of any shares
of Common Stock receivable upon the exercise of this Warrant above the amount
payable therefor upon such exercise immediately prior to such increase in par
value, (b) take all such action as may be necessary or appropriate in order that
the Company may validly and legally issue fully paid and nonassessable shares of
Common Stock, free and clear of any liens, claims, encumbrances and restrictions
(other than as provided herein) upon the exercise of this Warrant, and (c) use
its best efforts to obtain all such authorizations, exemptions or consents from
any public regulatory body having jurisdiction thereof as may be necessary to
enable the Company to perform its obligations under this Warrant.

         6. Fully Paid Stock; Taxes. The shares of Class A Common Stock
represented by each and every certificate for Warrant Shares delivered on the
exercise of this Warrant and the payment of the Exercise Price set forth herein
shall, at the time of such delivery, be validly issued and outstanding, fully
paid and nonassessable, and not subject to preemptive rights, and the Company
will take all such actions as may be necessary to assure that the par value or
stated value, if any, per share of the Class A Common Stock is at all times
equal to or less than the then Exercise Price. If the Exercise Price is at any
time less than the par value of the Warrant Shares or if the Warrant at any time
is exercisable by its delivery alone and without payment of any additional
consideration, the Company also covenants and agrees to cause to be taken such
action (whether by decreasing the par value of the Warrant Shares, the
conversion of the Warrant Shares from par value to no par value, or otherwise)

assignment permitted pursuant to this paragraph, the Holder and the Company
shall make appropriate arrangements, so that, if required, new Warrants shall be
issued to the Holder and the assignee. The Holder shall give the Company prior
written notice of the date that any such assignment shall become effective,

date, tenor and denomination.

         9. Holder Not Shareholder. This Warrant does not confer upon the Holder
any right to vote or to consent to or receive notice as a shareholder of the
Company, as such, in respect of any matters whatsoever, or any other rights or
liabilities as a shareholder, prior to the exercise hereof.

         10. Surrender. The Holder may at any time surrender all or a portion of
this Warrant for cancellation by transmitting same to the Company at its address

         12.       Miscellaneous.

                       (a)  Remedies. The Company agrees that monetary damages
         would not be adequate compensation for any loss incurred by reason of a
         breach by it of the provisions of this Warrant and hereby agrees to
         waive the defense in any action for specific performance that a remedy
         at law would be adequate. Accordingly, it is agreed that the Holder
         shall be entitled to an injunction, restraining order or other
         equitable relief to prevent breaches of this Agreement and to enforce
         specifically the terms and provisions hereof in any court of competent
         jurisdiction in the United States or any state thereof. Such remedies
         shall be cumulative and nonexclusive and shall be in addition to any
         other rights and remedies the parties may have under this Agreement.

                       (b)  No Inconsistent Agreements. The Company will not on
         or after the date of this Warrant enter into any agreement with respect
         to its Securities which is inconsistent with the rights granted to the
         Holder in this Warrant, otherwise conflicts with the provisions hereof
         or would be violated by the performance of the Company's obligations
         hereunder. The Company represents and warrants that the rights granted
         to the Holder hereunder do not in any way conflict with and are not
         inconsistent with the rights granted to the holders of the Company's
         Securities under any such agreements.

                       (c)  Successors and Assigns. Subject to the provisions of
         paragraph 7 hereof, this Warrant shall inure to the benefit of and be
         binding upon the successors and assigns of each of the parties.

                       (d)  Severability. In the event that any one or more of
         the provisions contained herein, or the application thereof in any
         circumstances, is held invalid, illegal or unenforceable, the validity,
         legality and enforceability of any such provision in every other
<PAGE>

         respect and of the remaining provisions contained herein shall not be
         affected or impaired thereby.

                       (e)  Amendments and Waivers. The provisions of this
         Warrant, including the provisions of this sentence, may not be amended,
         modified or supplemented, and waivers or consents to departures from
         the provisions hereof may not be given unless the Company has obtained
         the written consent of the Holder.

                       (f)  Headings.  The headings of this Warrant have been 
         inserted as a matter of convenience and shall not affect the 
         construction hereof.

                       (g)  Applicable Law. This Warrant shall be governed by
         and construed in accordance with the laws of the State of New York.
         Each party hereto agrees to submit to the nonexclusive jurisdiction of
         the courts in the City of New York in the State of New York in any
         action or proceeding arising out of or relating to this Agreement.

                       (h)  Registration Provisions. Except as provided in the
         Registration Rights Agreement, the Company is not required under the
         terms hereof to register any securities issued pursuant hereto, and the
         subsequent transfer of any shares issued pursuant hereto may require
         registration under the Securities Act as well as under applicable state
         laws. In the event the shares issued upon the exercise of this Warrant
         are not registered, the Holder acknowledges that any stock certificate
         evidencing shares acquired on exercise of this Warrant shall contain a
         legend restricting transferability substantially as follows:

                  THIS SECURITY HAS NOT BEEN REGISTERED OR QUALIFIED UNDER THE
                  SECURITIES ACT OF 1933, AS AMENDED ("ACT"), OR THE SECURITIES
                  LAWS OF ANY STATE AND MAY NOT BE OFFERED OR SOLD UNLESS
                  REGISTERED AND/OR QUALIFIED PURSUANT TO THE RELEVANT
                  PROVISIONS OF FEDERAL AND STATE SECURITIES LAWS OR AN
                  EXEMPTION FROM SUCH REGISTRATION OR QUALIFICATION IS
                  APPLICABLE. THEREFORE, NO SALE OR TRANSFER OF THIS SECURITY
                  SHALL BE VALID, AND THE ISSUER SHALL NOT BE REQUIRED TO GIVE
                  ANY EFFECT TO ANY SUCH TRANSACTION, UNLESS (A) SUCH
                  TRANSACTION SHALL HAVE BEEN REGISTERED UNDER THE ACT AND
                  QUALIFIED OR APPROVED UNDER APPROPRIATE STATE SECURITIES LAWS,
                  OR (B) THE ISSUER SHALL HAVE FIRST RECEIVED AN OPINION OF
                  COUNSEL (WHO MAY BE INTERNAL COUNSEL OF ADELPHIA) REASONABLY
                  SATISFACTORY TO IT THAT SUCH REGISTRATION, QUALIFICATION OR
                  APPROVAL IS NOT REQUIRED.

pursuant to an effective request therefor by the Holder, to effect, or is in the
process of effecting, a registration under the Securities Act for an
underwritten public offering in which Warrant Shares are, pursuant to the
Registration Rights Agreement, entitled to be included, or if the Company is in
default of any obligations created by this Warrant or by the Registration Rights
Agreement, the Termination Date shall be deemed to be, and the right to exercise
this Warrant and purchase Warrant Shares shall expire at 5:00 p.m., Eastern

all filings required to be made by the Company to obtain such approval or waiver
or to satisfy any other filing requirements, and the Holder thereafter
diligently continues to attempt to obtain such approval or waiver and/or
expiration of waiting period, then the Termination Date shall be deemed to be,
and the last date on which this Warrant can be exercised with respect to such
Warrant Shares shall be extended through, the date five Business Days after the
date on which a final ruling is made with respect to the filing(s) requesting
such approval or waiver or the expiration of such waiting period, as the case
may be. The Company agrees to provide reasonable assistance to, and cooperate
with, the Holder in making such filings required to be made by the Holder, and
the Company shall make all filings required to be made by the Company, for
obtaining such approvals or waivers or to satisfy any other filing requirements,
as are necessary for the exercise of this Warrant by the Holder not to

Warrant.

         2.        Exercise of Warrant.

                      (a)   This Warrant may be exercised, in whole at any time
         or in part from time to time, during the Exercise Period, by the Holder
         by the surrender of this Warrant (with the subscription duly executed)
         at the address set forth in paragraph 11(a) hereof, together with
         proper payment of the Exercise Price. Payment for the Warrant Shares to
         be purchased shall be made by wire transfer or certified or official
         bank check payable to the order of the Company. If this Warrant is
         exercised in part, this Warrant must be exercised for a whole number of
         shares of the Class A Common Stock, and the Holder is entitled to
         receive a new Warrant covering the number of Warrant Shares in respect
         of which this Warrant has not been exercised. Upon such surrender of
         this Warrant, the Company will issue a certificate or certificates in
         the name of the Holder for the number of shares of the Class A Common
         Stock to which the Holder shall be entitled. The Company shall not be
         required to issue a fractional share of Class A Common Stock upon any
         exercise of this Warrant, but the Company shall pay an amount in cash
         equal to the Current Market Price for one Warrant Share on the date the
         Warrant is exercised, multiplied by the fraction of a Warrant Share
         that would be issuable on the exercise of this Warrant.

                      (b)  In the event any Holder elects upon exercise to
         surrender this Warrant for payment of the applicable Exercise Price for
         the shares being purchased, this Warrant shall be surrendered and
         canceled. To the extent any Holder elects to pay all or part of the
         Exercise Price by surrendering this Warrant to the Company, the number
         of purchasable shares under this Warrant required to be surrendered as
         payment for the Exercise Price (the "Warrant Consideration Amount")
<PAGE>

         shall be equal to that number obtained by dividing (i) that amount of
         the aggregate Exercise Price that any Holder elects by written notice
         to the Company to pay by the application of this Warrant (such notice
         setting forth, in addition, the required reduction in the number of
         shares purchasable by this Warrant as calculated and shown in
         sufficient detail in accordance with the immediately succeeding
         clause), by (ii) the difference obtained by subtracting (A) the
         Exercise Price per share on the date of exercise from (B) the Current
         Market Price of the Warrant Shares on the date of exercise.

                      (c)   In the event of any exercise of the rights
         represented by this Warrant, (i) certificates for the shares of Warrant
         Shares so purchased shall be dated the date of such exercise and
         delivered to the Holder hereof within a reasonable time, not exceeding
         five Business Days after such exercise, and the Holder hereof shall be
         deemed for all purposes to be the Holder of the shares of Warrant
         Shares so purchased as of the date of such exercise, and (ii) unless
         this Warrant has expired, a new Warrant representing the number of
         shares equal to (A) the number of shares purchasable under this Warrant
         less (B) the sum of (1) the number of shares of Warrant Shares
         purchased upon exercise and (2) the Warrant Consideration Amount, if
         any, shall be issued to the Holder hereof within such time.

         3. Certain Adjustments. The Exercise Price and the kind and number of
shares of Class A Common Stock issuable upon exercise of this Warrant shall be
subject to adjustment as set forth below in this paragraph 3. The Company shall
give the registered Holder notice of any event described below which requires an
adjustment pursuant to this paragraph 3 in accordance with the provisions of
paragraph 4.

                       (a)  Stock Dividends, Subdivisions and Combinations.  If 
          at any time the Company shall:

                               (i)   fix a record date for the purpose of
                  determining the holders of its Common Stock entitled to
                  receive a dividend payable in, or other distribution of,
                  Additional Shares of Common Stock;

                               (ii)  subdivide its outstanding shares of Common 
                  Stock into a larger number of shares of Common Stock;

                               (iii) combine its outstanding shares of Common 
                  Stock into a smaller number of shares of Common Stock; or

                               (iv)   issue any shares of its capital stock or
                  other Securities by reclassification of the Common Stock
                  (other than pursuant to paragraph 3(c) below); then the
                  Exercise Price shall be proportionately decreased in the case
                  of such a dividend or distribution of Additional Shares of
                  Common Stock or such a subdivision, or proportionately
                  increased in the case of such a combination, or the kind of
                  capital stock or other securities of the Company which may be
                  purchased shall be adjusted in the case of such a
                  reclassification of the Common Stock, each on the record date
<PAGE>

                  for such dividend or distribution or effective date of such
                  subdivision, combination or reclassification, as the case may
                  be, such that the Holder shall be entitled to receive, upon
                  exercise of this Warrant, the aggregate number and kind of
                  shares of Common Stock which, if this Warrant had been fully
                  exercised immediately prior to such date, it would have owned
                  upon such exercise and been entitled to receive by virtue of
                  such dividend, distribution, subdivision, combination or
                  reclassification.

                        (b) Certain Other Dividends and Distributions. If at any
         time the Company shall fix a record date for the purpose of determining
         the holders of its Common Stock entitled to receive any dividend or
         other distribution (including any such distribution made in connection
         with a consolidation or merger, but excluding any distribution referred
         to in subparagraph (a) above) of:

                              (i)  any evidences of indebtedness, any shares
                  of its capital stock (including Convertible Securities but
                  excluding Common Stock) or any other securities or property of
                  any nature whatsoever (including cash but excluding normal
                  cash dividends or cash distributions permitted under
                  applicable law so long as in each case such cash is payable
                  solely out of earnings or earned surplus of the Company); or

                              (ii)   any warrants or other rights to subscribe
                  for or purchase any evidences of its indebtedness, any shares
                  of its capital stock (including Convertible Securities) or any
                  other of its securities or its property of any nature
                  whatsoever;

                  then the Exercise Price shall be adjusted to equal the
                  Exercise Price in effect prior to such distribution or
                  dividend multiplied by a fraction, (A) the numerator of which
                  shall be (1) the Current Market Price per share of the Class A
                  Common Stock on such record date minus (2) the amount
                  allocable to one share of Class A Common Stock of the fair
                  value of any and all such evidences of indebtedness, shares of
                  stock, other securities or property or warrants or other
                  subscription or purchase rights so distributable (as
                  determined in good faith by the Board of Directors of the
                  Company and, unless waived by the Holder, supported by an
                  opinion from an investment banking firm of nationally
                  recognized standing approved by the Holder, which approval
                  shall not be unreasonably withheld), and (B) the denominator
                  of which shall be such Current Market Price per share of Class
                  A Common Stock on such record date. Such adjustments shall be
                  made whenever such a record date is fixed. A reclassification
                  of the Common Stock (other than a change in par value, or from
                  par value to no par value or from no par value to par value)
                  into shares of Common Stock and shares of any other class of
                  stock shall be deemed a distribution by the Company to the
                  holders of its Common Stock of such shares of such other class
                  of stock within the meaning of this subparagraph (b) and, if
<PAGE>

                  the outstanding shares of Common Stock shall be changed into a
                  larger or smaller number of shares of Common Stock as a part
                  of such reclassification, such change shall be deemed a
                  subdivision or combination, as the case may be, of the
                  outstanding shares of Common Stock within the meaning of
                  subparagraph (a). The Company shall give to the Holder of this
                  Warrant not less than twenty (20) days' prior notice of any
                  record date referred to in this subparagraph (b) in accordance
                  with the provisions of paragraph 4.

                      (c)   Adjustments for Consolidation, Merger, Sale of 
         Assets, Reorganization, etc.

                              (i)   In case the Company after the date hereof
                  (A) shall consolidate with or merge into any other Person and
                  shall not be the continuing or surviving corporation of such
                  consolidation or merger, or (B) shall permit any other Person
                  to consolidate with or merge into the Company and the Company
                  shall be the continuing or surviving Person but, in connection
                  with such consolidation or merger, the Class A Common Stock
                  shall be changed into or exchanged for stock or other
                  securities of any other Person or cash or any other property,
                  or (C) shall transfer all or substantially all of its
                  properties or assets to any other Person or (D) shall effect a
                  capital reorganization or reclassification of the Class A
                  Common Stock (other than a capital reorganization or
                  reclassification for which adjustment in the Exercise Price is
                  provided in subparagraph 3(a) or subparagraph 3(b)), then, and
                  in the case of each such transaction, proper provision shall
                  be made so that, upon the basis and the terms and in the
                  manner provided in this Warrant, the Holder of this Warrant
                  shall be entitled (x) upon the exercise hereof at any time
                  after the consummation of such transaction, to the extent this
                  Warrant is not exercised prior to such transaction, or is
                  redeemed in connection with such transaction, to receive at
                  the Exercise Price in effect at the time immediately prior to
                  the consummation of such transaction in lieu of the Class A
                  Common Stock issuable upon such exercise of this Warrant prior
                  to such transaction the stock and other securities, cash and
                  property to which such Holder would have been entitled upon
                  the consummation of such transaction if such Holder had
                  exercised the rights represented by this Warrant immediately
                  prior thereto, subject to adjustments (subsequent to such
                  corporate action) as nearly equivalent as possible to the
                  adjustments provided for in this paragraph 3 or (y) to sell
                  this Warrant (or, at such Holder's election, a portion
                  thereof) to the Person continuing after or surviving such
                  event specified in clauses (a) through (d) above, or to the
                  Company (if the Company is the continuing or surviving Person)
                  at a sales price equal to the amount of cash, property and/or
                  the number of shares of Common Stock or other securities to
                  which a holder of the number of shares of Class A Common Stock
                  which would otherwise have been delivered upon the exercise of
                  this Warrant or the portion hereof redeemed would have been
                  entitled upon the effective date or closing of any such event
                  specified in clauses (a) through (d) above (the "Event
                  Consideration"), less the amount or portion of such Event
                  Consideration having a fair value equal to the aggregate
                  Exercise Price applicable to this Warrant or the portion
                  hereof so sold.

                           (ii) Notwithstanding anything contained in this
                  Warrant to the contrary, the Company will not effect any of
                  the transactions described in clauses (a) through (d) of the
                  above subparagraph (i) unless, prior to the consummation
<PAGE>

                  thereof, the surviving Person (if other than the Company) in
                  any merger or consolidation described in such clauses, each
                  Person which is to acquire the Company's assets in any
                  transaction described in clause (c) above, and each Person
                  (other than the Company) which may be required to deliver any
                  stock, securities, cash or property upon the exercise of this
                  Warrant as provided herein, shall assume, by written
                  instrument delivered to, and reasonably satisfactory to, the
                  Holder of this Warrant, (A) the obligations of the Company
                  under this Warrant (and if the Company shall survive the
                  consummation of such transaction, such assumption shall be in
                  addition to, and shall not release the Company from, any
                  continuing obligations of the Company under this Warrant) and
                  (B) the obligation to deliver to such Holder such shares of
                  stock, securities, cash or, property as, in accordance with
                  the foregoing provisions of this paragraph (c), such Holder
                  shall be entitled to receive, and such Person shall hive
                  similarly delivered to such Holder an opinion of counsel for
                  such Person, which counsel shall be reasonably satisfactory to
                  such Holder, stating that this Warrant shall thereafter
                  continue in full force and effect and the terms hereof
                  (including, without limitation, all of the provisions of this
                  paragraph 3) shall be applicable to the stock, securities,
                  cash or property which such Person may be required to deliver
                  upon any exercise of this Warrant or the exercise of any
                  rights pursuant hereto.

                               (iii) In case any of the transactions described
                  in clauses (A) through (D) of subparagraph (i) shall be
                  proposed to be effected (any such transaction a "Merger
                  Triggering Event"), the Holder of this Warrant may, and the
                  Company agrees that as a condition to the consummation of any
                  such Merger Triggering Event, the Company shall secure the
                  right of such Holder to, sell this Warrant (or, at such
                  Holder's election, a portion thereof) to the Person continuing
                  after or surviving such Merger Triggering Event, or the
                  Company (if the Company is the continuing or surviving
                  Person), simultaneously with, the effective date or closing of
                  such Merger Triggering Event, at a sale price equal to the
                  amount of cash, property and/or the number of shares of Common
                  Stock or other securities to which a holder of the number of
                  shares of Class A Common Stock which would otherwise have been
                  deliverable upon the exercise of this Warrant or the portion
                  hereof redeemed would have been entitled upon the effective
                  date or closing of such Merger Triggering Event (the
                  "Transaction Consideration"), less the amount or portion of
                  such Transaction Consideration having a fair value equal to
                  the aggregate Exercise Price applicable to this Warrant or the
                  portion hereof so sold. In the event that the Holder of this
                  Warrant exercises its rights under this subparagraph (iii) to
                  sell this Warrant (or a portion thereof) simultaneously with
                  the effective date or closing of any such Merger Triggering
                  Event, the Company shall not effect any such Merger Triggering
                  Event unless upon or prior to the consummation thereof such
                  amounts of cash, property, Common Stock, or other securities
                  are delivered to the Holder of this Warrant. Not less than
                  twenty (20) days' prior notice of any Merger Triggering Event
                  shall be given to the Holder of this Warrant in accordance
                  with paragraph 4.
<PAGE>

                       (d)  Adjustment of Number of Warrant Shares. Upon each
         adjustment of the Exercise Price, as the case may be, pursuant to
         subparagraph (a) or (b) of this paragraph 3, this Warrant shall be
         deemed to evidence the right to purchase, at the adjusted Exercise
         Price, that number of shares of Class A Common Stock obtained by
         multiplying the number of shares of Class A Common Stock covered by
         this Warrant immediately prior to such adjustment by the Exercise Price
         in effect prior to such adjustment and dividing the product so obtained
         by the Exercise Price in effect after such adjustment. If the Company
         shall be in default under any provision of this Warrant so that shares
         issued at the Exercise Price adjusted in accordance with the terms of
         this Warrant would not be validly issued, the adjustment of number of
         shares provided for in the foregoing sentence shall nonetheless be
         made, and the Holder of this Warrant shall be entitled to purchase such
         greater number of shares at the lowest price at which such shares may
         then be validly issued under applicable law. Such exercise shall not
         constitute a waiver of any claim arising against the Company by reason
         of its default under this Warrant.

                       (e)  When Adjustments to Be Made. No adjustment in the
         Exercise Price shall be required by this paragraph 3 if such adjustment
         either by itself or with other adjustments not previously made would
         require an increase or decrease of less than 1% in such price. Any
         adjustment representing a change of less than such minimum amount which
         is postponed shall be carried forward and made as soon as such
         adjustment, together with other adjustments required by this paragraph
         3 and not previously made, would result in a minimum adjustment.
         Notwithstanding the foregoing, any adjustment carried forward shall be
         made no later than ten Business Days prior to the Termination Date. All
         calculations under this subparagraph (h) shall be made to the nearest
         cent. For the purpose of any adjustment, any specified event shall be
         deemed to have occurred at the close of business on the date of its
         occurrence.

                       (f)  Fractional Interests. In computing adjustments under
         this paragraph 3, fractional interests in Common Stock shall be taken
         into account to the nearest whole share.

                       (g)  When Adjustments Not Required. If the Company shall
         fix a record date for the purpose of determining the holders of its
         Common Stock entitled to receive a dividend or distribution and shall,
         thereafter and before the distribution to stockholders thereof, legally
         abandon its plan to pay or deliver such dividend or distribution, then
         thereafter no adjustment shall be required by reason of the taking of
         such record and any such adjustment previously made in respect thereof
         shall be rescinded and annulled.

                       (h)  Certain Limitations. Subject to the provisions of
         paragraph 6, there shall be no adjustment of the Exercise Price
         hereunder to the extent that such adjustment would cause the Exercise
         Price to be less than the par value per share of the Common Stock,
         which par value shall not at any time while this Warrant is outstanding
         exceed $.01.

                       (i)  Other Action Affecting Common Stock. In case after
         the date hereof the Company shall take any action affecting its Common
         Stock, other than an action described in any of the foregoing
         subparagraphs (a) through (k) of this paragraph 3, inclusive, and the
         failure to make any adjustment would not fairly protect the purchase
<PAGE>

         rights represented by this Warrant in accordance with the essential
         intent and principle of this paragraph 3, then the Exercise Price
         and/or the number of Warrant Shares shall be adjusted in such manner
         and at such time as the Board of Directors of the Company may in good
         faith determine to be equitable in the circumstances.

         4.        Notices.

                  (a) Notices of Adjustments. Whenever the Exercise Price or the
         number of Warrant Shares shall be adjusted pursuant to paragraph 3, the
         Company shall forthwith deliver to the Holder a certificate prepared by
         the Company, setting forth, in reasonable detail, the event requiring
         the adjustment and the method by which such adjustment was calculated
         (including a description of the basis on which the Board of Directors
         of the Company determined the fair value of any evidences of
         indebtedness, shares of stock, other securities or property or warrants
         or other subscription or purchase rights), specifying the number of
         Warrant Shares then issuable hereunder, the Exercise Price after giving
         effect to such adjustment and (to the extent applicable) describing the
         number and kind of any other shares of stock for which the Warrant is
         exercisable. In the event that the Holder shall disagree with any such
         adjustment or with the terms of any new agreement to be entered into
         pursuant to paragraph 3(c), it shall notify the Company thereof and any
         disagreement shall be resolved by an investment banking firm of
         nationally recognized standing mutually agreeable to the Company and
         the Holder, or if the Company and the Holder are unable to agree upon
         an investment banking firm, an investment banking firm selected by an
         investment banking firm chosen by the Company and an investment banking
         firm chosen by the Holder.

                       (b)  Notices of Corporate Action.  In the event of any of
         the following:

                          (i)        any taking by the Company of a record of
                  the holders of any class of securities for the purpose of
                  determining the holders thereof who are entitled to receive
                  any dividend or other distribution, or any right to subscribe
                  for, purchase or otherwise acquire any shares of stock of any
                  class or any other securities or property, or to receive any
                  other right, which dividend, distribution or other right
                  affects the rights of the Holder, or

                          (ii)       any capital reorganization of the Company,
                  any reclassification or recapitalization of the capital stock
                  of the Company or any consolidation or merger involving the
                  Company and any other party or any transfer of all or
                  substantially all the assets of the Company to any other
                  party, or

                          (iii)      any voluntary or involuntary dissolution,
                  liquidation or winding-up of the Company;

The Company will mail to the Holder a notice specifying (A) the date or expected
date on which any such record is to be taken for the purpose of such dividend,
distribution or right and the amount and character of any such dividend,
distribution or right and (B) the date or expected date on which any such
<PAGE>

reorganization, reclassification, recapitalization, consolidation, merger,
transfer, dissolution, liquidation or winding-up is to take place and the time,
if any such time is to be fixed, as of which the holders of record of Class A
Common Stock (or other securities) shall be entitled to exchange their shares of
Class A Common Stock (or other securities) for the securities or other property
deliverable upon such reorganization, reclassification, recapitalization,
consolidation, merger, transfer, dissolution, liquidation or winding-up. Such
notice shall be mailed at least twenty (20) days prior to the date herein
specified, in the case of any date referred to in the foregoing subdivision (A),
and at least twenty (20) days prior to the date therein specified, in the case
of the date referred to in the foregoing subdivision (B).

         5. Reservation of Warrant Shares. The Company agrees that, upon
commencement of the Exercise Period and at all times prior to the Termination
Date, the Company will at all times have authorized and in reserve, and will
keep available, solely for issuance or delivery upon the exercise of this
Warrant, the shares of the Class A Common Stock and other securities and
properties as from time to time shall be receivable upon the exercise of this
Warrant, free and clear of all restrictions on sale or transfer and free and
clear of all preemptive rights. The Company shall not by any action, including,
without limitation, amending its certificate of incorporation or through any
reorganization, transfer of assets, consolidation, merger, dissolution, issue or
sale of securities or any other voluntary action, avoid or seek to avoid the
observance or performance of any of the terms of this Warrant, but will at all
times in good faith assist in the carrying out of all such terms and in the
taking of all such actions as may be necessary or appropriate to protect the
rights of the Holders hereof against impairment. Without limiting the generality
of the foregoing, the Company will (a) not increase the par value of any shares
of Common Stock receivable upon the exercise of this Warrant above the amount
payable therefor upon such exercise immediately prior to such increase in par
value, (b) take all such action as may be necessary or appropriate in order that
the Company may validly and legally issue fully paid and nonassessable shares of
Common Stock, free and clear of any liens, claims, encumbrances and restrictions
(other than as provided herein) upon the exercise of this Warrant, and (c) use
its best efforts to obtain all such authorizations, exemptions or consents from
any public regulatory body having jurisdiction thereof as may be necessary to
enable the Company to perform its obligations under this Warrant.

         6. Fully Paid Stock; Taxes. The shares of Class A Common Stock
represented by each and every certificate for Warrant Shares delivered on the
exercise of this Warrant and the payment of the Exercise Price set forth herein
shall, at the time of such delivery, be validly issued and outstanding, fully
paid and nonassessable, and not subject to preemptive rights, and the Company
will take all such actions as may be necessary to assure that the par value or
stated value, if any, per share of the Class A Common Stock is at all times
equal to or less than the then Exercise Price. If the Exercise Price is at any
time less than the par value of the Warrant Shares or if the Warrant at any time
is exercisable by its delivery alone and without payment of any additional
consideration, the Company also covenants and agrees to cause to be taken such
action (whether by decreasing the par value of the Warrant Shares, the
conversion of the Warrant Shares from par value to no par value, or otherwise)
as will permit the exercise of this Warrant without any additional payment by
the Holder hereof (other than payment of the Exercise Price, if any, and
applicable transfer taxes, if any) and the issuance of the Warrant Shares, which
Warrant Shares, upon such issuance, will be fully paid and non-assessable. The
Company further covenants and agrees that it will pay, when due and payable, any
<PAGE>

and all federal and state stamp, original issue or similar taxes which may be
payable in respect of the issuance of any Warrant Shares or certificate therefor
and that the Warrant Shares will be otherwise free from all taxes, liens and
charges with respect to issuance.

         7. Transferability. Upon execution and delivery of an assignment
instrument substantially in the form attached hereto, as assignee shall be a
party to this Agreement and shall have the rights and obligations of the Holder,
to the extent of such assignment, and the Holder shall be released from its
obligations hereunder to a corresponding extent. Upon the consummation of any
assignment permitted pursuant to this paragraph, the Holder and the Company
shall make appropriate arrangements, so that, if required, new Warrants shall be
issued to the Holder and the assignee. The Holder shall give the Company prior
written notice of the date that any such assignment shall become effective,
which date shall be no less than ten days after the date such notice is given.

         8. Loss, etc., of Warrant. Upon receipt of evidence satisfactory to the
Company of the loss, theft, destruction or mutilation of this Warrant, and of
indemnity or bond reasonably satisfactory to the Company, if lost, stolen or
destroyed, and upon surrender and cancellation of this Warrant, if mutilated,
the Company shall execute and deliver to the Holder a new Warrant of the like
date, tenor and denomination.

         9. Holder Not Shareholder. This Warrant does not confer upon the Holder
any right to vote or to consent to or receive notice as a shareholder of the
Company, as such, in respect of any matters whatsoever, or any other rights or
liabilities as a shareholder, prior to the exercise hereof.

         10. Surrender. The Holder may at any time surrender all or a portion of
this Warrant for cancellation by transmitting same to the Company at its address
set forth herein accompanied by a written notice setting forth the Holder's
intention to surrender this Warrant (or such portion) for cancellation and upon
such transmittal by the Holder, this Warrant (or such portion) shall become null
and void and of no further force and effect.

         11. Notices. Any notice, demand, request, consent, approval,
declaration, delivery or other communication hereunder to be made pursuant to
the provisions of this Warrant shall be sufficiently given or made if in writing

         12.       Miscellaneous.

                      (a)   Remedies. The Company agrees that monetary damages
         would not be adequate compensation for any loss incurred by reason of a
         breach by it of the provisions of this Warrant and hereby agrees to
         waive the defense in any action for specific performance that a remedy
         at law would be adequate. Accordingly, it is agreed that the Holder
         shall be entitled to an injunction, restraining order or other
         equitable relief to prevent breaches of this Agreement and to enforce
         specifically the terms and provisions hereof in any court of competent
         jurisdiction in the United States or any state thereof. Such remedies
         shall be cumulative and nonexclusive and shall be in addition to any
         other rights and remedies the parties may have under this Agreement.

                      (b)   No Inconsistent Agreements. The Company will not on
         or after the date of this Warrant enter into any agreement with respect
         to its Securities which is inconsistent with the rights granted to the
         Holder in this Warrant, otherwise conflicts with the provisions hereof
         or would be violated by the performance of the Company's obligations
         hereunder. The Company represents and warrants that the rights granted
         to the Holder hereunder do not in any way conflict with and are not
         inconsistent with the rights granted to the holders of the Company's
         Securities under any such agreements.

                      (c)  Successors and Assigns. Subject to the provisions of
         paragraph 7 hereof, this Warrant shall inure to the benefit of and be
         binding upon the successors and assigns of each of the parties.

                      (d)  Severability. In the event that any one or more of
         the provisions contained herein, or the application thereof in any
         circumstances, is held invalid, illegal or unenforceable, the validity,
         legality and enforceability of any such provision in every other
         respect and of the remaining provisions contained herein shall not be
         affected or impaired thereby.
<PAGE>

                      (e)   Amendments and Waivers. The provisions of this
         Warrant, including the provisions of this sentence, may not be amended,
         modified or supplemented, and waivers or consents to departures from
         the provisions hereof may not be given unless the Company has obtained
         the written consent of the Holder.

                      (f)   Headings.  The headings of this Warrant have been
         inserted as a matter of convenience and shall not affect the 
         construction hereof.

                      (g)   Applicable Law. This Warrant shall be governed by
         and construed in accordance with the laws of the State of New York.
         Each party hereto agrees to submit to the nonexclusive jurisdiction of
         the courts in the City of New York in the State of New York in any
         action or proceeding arising out of or relating to this Agreement.

                      (h)   Registration Provisions. Except as provided in the
         Registration Rights Agreement, the Company is not required under the
         terms hereof to register any securities issued pursuant hereto, and the
         subsequent transfer of any shares issued pursuant hereto may require
         registration under the Securities Act as well as under applicable state
         laws. In the event the shares issued upon the exercise of this Warrant
         are not registered, the Holder acknowledges that any stock certificate
         evidencing shares acquired on exercise of this Warrant shall contain a
         legend restricting transferability substantially as follows:

                  THIS SECURITY HAS NOT BEEN REGISTERED OR QUALIFIED UNDER THE
                  SECURITIES ACT OF 1933, AS AMENDED ("ACT"), OR THE SECURITIES
                  LAWS OF ANY STATE AND MAY NOT BE OFFERED OR SOLD UNLESS
                  REGISTERED AND/OR QUALIFIED PURSUANT TO THE RELEVANT
                  PROVISIONS OF FEDERAL AND STATE SECURITIES LAWS OR AN
                  EXEMPTION FROM SUCH REGISTRATION OR QUALIFICATION IS
                  APPLICABLE. THEREFORE, NO SALE OR TRANSFER OF THIS SECURITY
                  SHALL BE VALID, AND THE ISSUER SHALL NOT BE REQUIRED TO GIVE
                  ANY EFFECT TO ANY SUCH TRANSACTION, UNLESS (A) SUCH
                  TRANSACTION SHALL HAVE BEEN REGISTERED UNDER THE ACT AND
                  QUALIFIED OR APPROVED UNDER APPROPRIATE STATE SECURITIES LAWS,
                  OR (B) THE ISSUER SHALL HAVE FIRST RECEIVED AN OPINION OF
                  COUNSEL (WHO MAY BE INTERNAL COUNSEL OF MCI) REASONABLY
                  SATISFACTORY TO IT THAT SUCH REGISTRATION, QUALIFICATION OR
                  APPROVAL IS NOT REQUIRED.
