           case of a transfer, is not (1) a Broker-Dealer, (2) a Person
           participating in the distribution of the Senior Notes issued in the
           Exchange Offer or (3) a Person who is an affiliate (as defined in
           Rule 144) of the Company;

                (B) any such transfer is effected pursuant to the Shelf
           Registration Statement in accordance with the Registration Rights
           Agreement;

                (C) any such transfer is effected by a Participating

           including the certifications in item (1)(d) thereof;

           proposes to transfer such Notes to a Person who shall take delivery
           thereof in the form of an Unrestricted Definitive Note, a certificate
           from such Holder in the form of Exhibit B hereto, including the

      charge payable in connection therewith (other than any such transfer taxes
      or similar governmental charge payable upon exchange or transfer pursuant
      to Sections 2.10, 3.08, 4.09, 4.10 and 9.05 hereof).

           (v) The Company shall not be required (A) to issue, to register the

SECTION 2.07. REPLACEMENT SENIOR NOTES.

           If any mutilated Senior Note is surrendered to the Trustee, or the
Company and the Trustee receives evidence to its satisfaction of the
destruction, loss or theft of any Senior Note, the Company shall issue and the
Trustee, upon the written order of the Company signed by two Officers of the
Company, shall authenticate a replacement Senior Note if the Trustee's
requirements are met. If required by the Trustee or the Company, an indemnity
bond must be supplied by the Holder that is sufficient in the judgment of the
Trustee and the Company to protect the Company, the Trustee, any Agent and any
authenticating agent from any loss that any of them may suffer if a Senior Note
is replaced. The Company may charge for its expenses in replacing a Senior Note.

           Every replacement Senior Note is an additional obligation of the
Company and shall be entitled to all of the benefits of this Indenture equally
and proportionately with all other Senior Notes duly issued hereunder.

SECTION 2.08. OUTSTANDING SENIOR NOTES.

           The Senior Notes outstanding at any time are all the Senior Notes
authenticated by the Trustee except for those cancelled by it, those delivered
to it for cancellation, those reductions in the interest in a Global Note
effected by the Trustee in accordance with the provisions hereof, and those
described in this Section as not outstanding. Except as set forth in Section
2.09 hereof, a Senior Note does not cease to be outstanding because the Company
or an Affiliate of the Company holds the Senior Note.

           If a Senior Note is replaced pursuant to Section 2.07 hereof, it
ceases to be outstanding unless the Trustee receives proof satisfactory to it
that the replaced Senior Note is held by a bona fide purchaser.

           If the principal amount of any Senior Note is considered paid under
Section 4.01 hereof, it ceases to be outstanding and interest on it ceases to
accrue.

           If the Paying Agent (other than the Company, a Subsidiary or an
Affiliate of any thereof) holds, on a redemption date or maturity date, money
sufficient to pay Senior Notes payable on that date, then on and after that date
such Senior Notes shall be deemed to be no longer outstanding and shall cease to
accrete or accrue interest.

SECTION 2.09. TREASURY SENIOR NOTES.

           In determining whether the Holders of the required principal amount
of Senior Notes have concurred in any direction, waiver or consent, Senior Notes
owned by the Company, or by any Affiliate thereof shall be considered as though
not outstanding, except that for the purposes of determining whether the Trustee
shall be protected in relying on any such direction, waiver or consent, only
Senior Notes that a Trustee knows are so owned shall be so disregarded.

SECTION 2.10. TEMPORARY SENIOR NOTES.

           Until definitive Senior Notes are ready for delivery, the Company may
prepare and the Trustee shall authenticate temporary Senior Notes upon a written
order of the Company signed by two Officers of


                                                       33



<PAGE>



the Company. Temporary Senior Notes shall be substantially in the form of
definitive Senior Notes but may have variations that the Company considers
appropriate for temporary Senior Notes and as shall be reasonably acceptable to
the Trustee. Without unreasonable delay, the Company shall prepare and the
Trustee shall authenticate definitive Senior Notes in exchange for temporary
Senior Notes.

           Holders of temporary Senior Notes shall be entitled to all of the
benefits of this Indenture.

SECTION 2.11. CANCELLATION.

           The Company at any time may deliver Senior Notes to the Trustee for
cancellation. The Registrar and Paying Agent shall forward to the Trustee any
Senior Notes surrendered to them for registration of transfer, exchange or
payment. The Trustee and no one else shall cancel all Senior Notes surrendered
for registration of transfer, exchange, payment, replacement or cancellation and
shall destroy cancelled Senior Notes (subject to the record retention
requirement of the Exchange Act). Certification of the destruction of all
cancelled Senior Notes shall be delivered to the Company. The Company may not
issue new Senior Notes to replace Senior Notes that it has paid or that have
been delivered to the Trustee for cancellation.

SECTION 2.12. RECORD DATE.

           The record date for purposes of determining the identity of Holders
of the Senior Notes entitled to vote or consent to any action by vote or consent
authorized or permitted under this Indenture shall be determined as provided for
in TIA ' 316 (c).

SECTION 2.13. DEFAULTED INTEREST.

           If the Company defaults in a payment of interest on the Senior Notes,
it shall pay the defaulted interest in any lawful manner plus, to the extent
lawful, interest payable on the defaulted interest, to the Persons who are
Holders on a subsequent special record date, in each case at the rate provided
in the Senior Notes and in Section 4.01 hereof. The Company shall notify the
Trustee in writing of the amount of defaulted interest proposed to be paid on
each Senior Note and the date of the proposed payment. The Company shall fix or
cause to be fixed each such special record date and payment date, provided that
no such special record date shall be less than 10 days prior to the related
payment date for such defaulted interest. At least 15 days before the special
record date, the Company (or, upon the written request of the Company, the
Trustee in the name and at the expense of the Company) shall mail or cause to be
mailed to Holders a notice that states the special record date, the related
payment date and the amount of such interest to be paid.

           If the Company elects to redeem Senior Notes pursuant to the optional
redemption provisions of Section 3.07 hereof, it shall furnish to the Trustee,
at least 45 days but not more than 60 days before a redemption date, an
Officers' Certificate setting forth (i) the clause of this Indenture pursuant to
which the redemption shall occur, (ii) the redemption date, (iii) the principal
amount of Senior Notes to be redeemed and (iv) the redemption price.

SECTION 3.02. SELECTION OF SENIOR NOTES TO BE REDEEMED.

           If less than all of the Senior Notes are to be redeemed at any time,
the Trustee shall select the Senior Notes to be redeemed among the Holders of
the Senior Notes in compliance with the requirements of the principal national
securities exchange, if any, on which the Senior Notes are listed or, if the
Senior Notes are not so listed, on a pro rata basis, by lot or in accordance
with any other method the Trustee considers fair and appropriate. In the event
of partial redemption by lot, the particular Senior Notes to be redeemed shall
be selected, unless otherwise provided herein, not less than 30 nor more than 60
days prior to the redemption date by the Trustee from the outstanding Senior
Notes not previously called for redemption.

           The Trustee shall promptly notify the Company in writing of the
Senior Notes selected for redemption and, in the case of any Senior Note
selected for partial redemption, the principal amount thereof to be redeemed.
Senior Notes and portions of Senior Notes selected shall be in amounts of $1,000
or whole multiples of $1,000; except that if all of the Senior Notes of a Holder
are to be redeemed, the entire outstanding amount of Senior Notes held by such
Holder, even if not a multiple of $1,000, shall be redeemed. Except as provided
in the preceding sentence, provisions of this Indenture that apply to Senior
Notes called for redemption also apply to portions of Senior Notes called for
redemption.

SECTION 3.03. NOTICE OF REDEMPTION.

           Subject to the provisions of Section 3.09 hereof, at least 30 days
but not more than 60 days before a redemption date, the Company shall mail or
cause to be mailed, by first class mail, a notice of redemption to each Holder
whose Senior Notes are to be redeemed at its registered address.

           The notice shall identify the Senior Notes to be redeemed and shall
state:

           (a)  the redemption date;

           (b)  the redemption price;

           (c) if any Senior Note is being redeemed in part, the portion of the
      principal amount of such Senior Note to be redeemed and that, after the
      redemption date upon surrender of such Senior Note, a new Senior Note or
      Senior Notes in principal amount equal to the unredeemed portion shall be
      issued upon cancellation of the original Senior Note;

           (d)  the name and address of the Paying Agent;

           (e)  that Senior Notes called for redemption must be surrendered to
      the Paying Agent to collect the redemption price;

           (f) that, unless the Company defaults in making such redemption
      payment, interest on Senior Notes called for redemption ceases to accrue
      on and after the redemption date;

           (g) the paragraph of the Senior Notes and/or Section of this
      Indenture pursuant to which the Senior Notes called for redemption are
      being redeemed; and


                                                       35



<PAGE>




           (h) that no representation is made as to the correctness or accuracy
      of the CUSIP number, if any, listed in such notice or printed on the
      Senior Notes.

           At the Company's request, the Trustee shall give the notice of
redemption in the Company's name and at its expense; provided, however, that the
Company shall have delivered to the Trustee, at least 45 days prior to the
redemption date, an Officers' Certificate requesting that the Trustee give such
notice and setting forth the information to be stated in such notice as provided
in the preceding paragraph.

SECTION 3.04. EFFECT OF NOTICE OF REDEMPTION.

           Once notice of redemption is mailed in accordance with Section 3.03
hereof, Senior Notes called for redemption become irrevocably due and payable on
the redemption date at the redemption price. A notice of redemption may not be
conditional.

SECTION 3.05. DEPOSIT OF REDEMPTION PRICE.

           One Business Day prior to the redemption date, the Company shall
deposit with the Trustee or with the Paying Agent money sufficient to pay the
redemption price of and accrued interest on all Senior Notes to be redeemed on
that date. The Trustee or the Paying Agent shall promptly return to the Company
any money deposited with the Trustee or the Paying Agent by the Company in
excess of the amounts necessary to pay the redemption price of, accrued interest
on and Liquidated Damages, if any, all Senior Notes to be redeemed.

           If the Company complies with the provisions of the preceding
paragraph, on and after the redemption date, interest shall cease to accrue on
the Senior Notes or the portions of Senior Notes called for redemption. If a
Senior Note is redeemed on or after an interest record date but on or prior to
the related interest payment date, then any accrued and unpaid interest and
Liquidated Damages, if any, shall be paid to the Person in whose name such
Senior Note was registered at the close of business on such record date. If any
Senior Note called for redemption shall not be so paid upon surrender for
redemption because of the failure of the Company to comply with the preceding
paragraph, interest shall be paid on the unpaid principal, from the redemption
date until such principal is paid, and to the extent lawful on any interest not
paid on such unpaid principal, in each case at the rate provided in the Senior
Notes and in Section 4.01 hereof.

SECTION 3.06. SENIOR NOTES REDEEMED IN PART.

           Upon surrender of a Senior Note that is redeemed in part, the Company
shall issue and, upon the Company's written request, the Trustee shall
authenticate for the Holder at the expense of the Company a new Senior Note
equal in principal amount to the unredeemed portion of the Senior Note
surrendered.

      Holder, the principal amount of the Senior Note the Holder delivered for
      purchase and a statement that such Holder is

                (h) that, if the aggregate principal amount of Senior Notes
      surrendered by Holders exceeds the amount required to be purchased
      pursuant to Section 4.10 hereof, the Company shall select the Senior Notes
      to be purchased on a pro rata basis (with such adjustments as may be
      deemed appropriate by the Company so that only Senior Notes in
      denominations of $1,000, or integral multiples thereof, shall be
      purchased); and

                (i) that Holders whose Senior Notes were purchased only in part
      shall be issued new Senior Notes equal in principal amount to the
      unpurchased portion of the Senior Notes surrendered (or transferred by
      book-entry transfer).

           On or before the Purchase Date, the Company shall, to the extent
lawful, accept for payment, on a pro rata basis to the extent necessary, the
Senior Notes or portions thereof tendered or required to be purchased pursuant
to the Asset Sale Offer, or if less than the amount so required to be purchased
has been tendered, all Senior Notes tendered, and shall deliver to the Trustee

accepted for payment by the Company in accordance with the terms of Section 4.10
hereof and this Section 3.09. The Company, the Depository or the Paying Agent,
as the case may be, shall promptly (but in any case not later than five days
after the Purchase Date) mail or deliver to each tendering Holder an amount
equal to the purchase price of the Senior Notes tendered by such Holder and
accepted by the Company for purchase, and the Company shall promptly issue a new
Senior Note, and the Trustee, upon written request from the Company shall
authenticate and mail or deliver such new Senior Note to such Holder, in a
principal amount equal to any unpurchased portion of the Senior Note
surrendered. Any Senior Note not so accepted shall be promptly mailed or
delivered by the Company to the Holder thereof. The Company shall publicly
announce the results of the Asset Sale Offer on the Purchase Date.

           Other than as specifically provided in this Section 3.09, any
purchase pursuant to this Section 3.09 shall be made pursuant to the provisions
of Sections 3.01 through 3.06 hereof.

                      any Permitted Joint Venture pursuant to Credit
                      Agreement(s), provided that the aggregate principal amount
                      of such Credit Agreement(s) at any one time outstanding
                      under this clause (i) does not exceed $50.0 million for

                      Ventures combined;

           (ii)       the incurrence of Vendor Debt by the Company, any
                      Subsidiary (other than a General Partner Subsidiary) or
                      any Permitted Joint Venture, provided that the aggregate
                      principal amount of such Vendor Debt does not exceed 80%
                      of the total cost of the Telecommunications Related Assets
                      financed therewith (or 100% of the total cost of the
                      Telecommunications Related Assets financed therewith if
                      such Vendor Debt was extended for the purchase of tangible
                      physical assets and was so financed by the vendor thereof
                      or an affiliate of such vendor);

           (iii)      Refinancing Indebtedness;

           (iv)       the incurrence of Indebtedness by the Company not to

                      cash proceeds received by the Company after the date
                      hereof from the issuance and sale of its Capital Stock
                      (other than Disqualified Stock) plus (b) the fair market
                      value at the time of issuance of Equity Interests (other
                      than Disqualified Stock) issued after the date of this
                      Indenture in connection with any acquisition of a
                      Telecommunications Related Business, in each case to a
                      Person other than a Subsidiary or a Joint Venture of the
                      Company, provided that such Indebtedness (y) does not
                      mature prior to the Stated Maturity of the Senior Notes
                      and has a Weighted Average Life to Maturity longer than
                      the Senior Notes and (z) is subordinated to the Senior
                      Notes;

           (v)        the incurrence by the Company of Indebtedness (in addition
                      to Indebtedness permitted by any other clause of this
                      paragraph) in an aggregate principal amount (or accreted
                      value, as applicable) at any time outstanding not to
                      exceed $10.0 million;

           (vi)       the incurrence by any Restricted Joint Venture of
                      Non-Recourse Debt, provided that if any Non-Recourse Debt
                      of a Restricted Joint Venture ceases to be Non-Recourse
                      Debt, such event shall be deemed to constitute an
                      incurrence of Indebtedness as of the date such
                      Indebtedness ceases to be Non-Recourse Debt;

           (vii)      the guarantee of Indebtedness by a General Partner
                      Subsidiary in connection with the incurrence of
                      Indebtedness by the Restricted Joint Venture of which such
                      General Partner Subsidiary is a general partner;

           (viii)     the incurrence by any Subsidiary (other than a General
                      Partner Subsidiary) or any Permitted Joint Venture of
                      Indebtedness (including, without limitation, Acquired
                      Indebtedness) so long as all of the net proceeds of such
                      incurrence are used by such


                                                       45



<PAGE>



                      Subsidiary or Permitted Joint Venture, as the case may be,
                      directly in connection with the design, construction,
                      development or acquisition of a Telecommunications Service
                      Market; provided that, as of the last day of the Company's
                      most recently ended fiscal quarter for which internal
                      financial statements are available immediately preceding
                      the date on which such Indebtedness is incurred, either:
                      (a) the aggregate principal amount of all Indebtedness of
                      such Subsidiary or such Permitted Joint Venture does not
                      exceed 1.75 times the Invested Equity Capital of such
                      Subsidiary or such Permitted Joint Venture; or (b) the
                      Consolidated Leverage Ratio of such Subsidiary or such
                      Permitted Joint Venture would not have been greater than
                      3.5 to 1.0, in each case determined on a pro forma basis
                      (including pro forma application of the net proceeds
                      therefrom) as if such Indebtedness had been incurred at
                      the beginning of such fiscal quarter; provided, further
                      that any Indebtedness incurred by any Subsidiary of the
                      Company or any Permitted Joint Venture (other than Related
                      Networks) pursuant to this clause (viii) shall be
                      non-recourse with respect to the Company or any other
                      Subsidiary of the Company or any other Joint Venture; and

           (ix)       the incurrence by the Company of the Existing
                      Indebtedness.

           For purposes of this Section 4.09, in the event that the Company
proposes to incur Indebtedness pursuant to clause (iv) above, the Company shall,
simultaneously with the incurrence of such Indebtedness, deliver to the Trustee
a resolution of the Board of Directors set forth in an Officers' Certificate
stating that the sale or sales of Capital Stock forming the basis for the
incurrence of such Indebtedness (i) constitutes a long term investment in the
Company and (ii) has not been made for the purpose of circumventing this Section
4.09. In the event that the Company rescinds, reverses or unwinds such sale of
Capital Stock or otherwise returns or refunds all or any portion of the net cash
proceeds of such sale of Capital Stock (whether by dividend, distribution or
otherwise) within 270 days of the date of the incurrence of such Indebtedness,
such Indebtedness will be deemed to be incurred on the date of, and immediately
after giving effect to, such rescission, reversal, unwinding, return or refund.

           For purposes of this Section 4.09, in the event that a Restricted
Joint Venture becomes a Permitted Joint Venture or otherwise ceases to be a
Restricted Joint Venture, all of the then outstanding Indebtedness of such
entity shall be deemed to have been incurred as of the date that such Restricted
Joint Venture becomes a Permitted Joint Venture or otherwise ceases to be a
Restricted Joint Venture.


SECTION 4.10. ASSET SALES.

           The Company shall not, and shall not permit any Subsidiary to,
directly or indirectly, whether in a single transaction or a series of related
transactions occurring within any twelve-month period, make any Asset Sale,
unless:

                (i)   the Company or the Subsidiary, as the case may be,
                      receives consideration at the time of such Asset Sale at
                      least equal to the fair market value (as determined in
                      good faith by the Board of Directors) for the shares or
                      assets sold or otherwise disposed of; and

                (ii)  at least 85% of such consideration consists of cash,



                                                       46



<PAGE>



provided that

           (A)  an amount equal to the fair market value (as determined in good
                faith by the Board of Directors) of:

                (1)   Telecommunications Related Assets received by the Company
                      or any Subsidiary from the transferee that will be used by
                      the Company or such Subsidiary in the operation of a
                      Telecommunications Business;

                (2)   the Voting Stock of any Person engaged in a
                      Telecommunications Business received by the Company or any
                      Subsidiary; provided that on the date such Voting Stock is
                      received, such Investment in Voting Stock constitutes a
                      Permitted Joint Venture Investment; or

                (3)   the publicly tradeable Voting Stock of any person engaged
                      in the Telecommunications Business received by the Company
                      or any Subsidiary as consideration for a sale of an Equity
                      Interest in any Restricted Joint Venture,

      shall, for the purposes of this Section 4.10, be deemed to be cash which
      was applied in accordance with the first sentence of the penultimate
      paragraph of this Section 4.10; and

           (B)  in the event that any of Hyperion Telecommunications of
                Pennsylvania, Inc., Hyperion Telecommunications of Tennessee,
                Inc. or Hyperion Telecommunications of New York, Inc. sell their
                respective partnership interests in the partnerships to which
                each is a partner to the respective partnerships in the manner
                specified by the applicable partnership agreement, (1) the
                principal amount of any seller note issued to the Company or any
                of its Wholly Owned Subsidiaries shall be deemed to be cash for
                purposes of this Section 4.10 and (2) the payments of principal
                pursuant to such seller note shall be deemed to be
                 Net Cash Proceeds (for purposes of the penultimate paragraph of
                 this Section 4.10) as and when such payments are received.

           For purposes of this Section 4.10, the first $1.0 million of Net Cash
Proceeds received from Asset Sales (other than Asset Sales of Stock Collateral)
in any fiscal year shall not be subject to the restrictions contained in this
section.

           In determining the fair market value with respect to any Asset Sale
or series of related Asset Sales involving aggregate consideration in excess of
$10.0 million, the Board of Directors of the Company must obtain an opinion as
to the fairness to the Holders of Senior Notes of such Asset Sales from a
financial point of view issued by a nationally recognized investment banking
firm with total assets in excess of $1.0 billion; provided that no such opinion
shall be required if such Asset Sale is in accordance with the terms of any
Local Partner Agreement to which the Company or any of its Subsidiaries is a
party on the date hereof.

           The Company may apply the Net Cash Proceeds from any Asset Sale to an
investment in Telecommunications Related Assets in a Telecommunications Service
Market within 180 days after such Asset Sale; provided that if the Company
determines to make such investment in a New Telecommunications Service Market,
the Company shall be deemed to have complied with the first clause of this
sentence if, the Company (y) within 180 days of such Asset Sale, delivers to the
Trustee a resolution adopted by a majority of the Board of Directors set forth
in an Officer's Certificate certifying that the Company intends to utilize


                                                       47



<PAGE>



the Net Cash Proceeds of such Asset Sale to invest in a specific new
Telecommunications Service Market and (z) completes such investment within 360
days of such Asset Sale. The Company shall be deemed to have completed its
investment for purposes of the preceding clause (z), so long as the Company has
(i) a business plan that sets forth the Company's investment plans for the
applicable Telecommunications Service Market and (ii) issued all material
purchase orders to the appropriate parties that are necessary to complete such
business plan. A first priority security interest securing the Company's
obligations under the Senior Notes shall be granted in all Telecommunications
Related Assets acquired in whole or in part with the proceeds of any Asset Sale
of Stock Collateral and the Company will take or cause to be taken all actions
necessary to cause such first priority security interest to be granted
concurrently with the acquisitions of such Telecommunications Related Assets.
Any Net Cash Proceeds from an Asset Sale that are not invested as provided in
the two preceding sentences shall constitute Excess Proceeds. When the aggregate
amount of Excess Proceeds exceeds $2.5 million, the Company shall commence to
purchase (an "Asset Sale Offer") the maximum principal amount of Senior Notes
and 13% Notes (on a pro rata basis based upon the relative aggregate principal
amount of 13% Notes (or, if prior to April 15, 2001, the aggregate Accreted
Value, as such term is defined in the 13% Note Indenture, of 13% Notes) and
Senior Notes then outstanding) that may be purchased out of the Excess Proceeds,
at an offer price in cash equal to 100% of the aggregate principal amount
thereof, plus accrued and unpaid interest to the date of repurchase (or, in the
case of 13% Notes prior to April 15, 2001, at a purchase price equal to 100% of
the Accreted Value thereof as of the date of purchase) in accordance with the
procedures set forth in this Indenture, provided, that, in the event of an Asset
Sale Offer as a result (in whole or in part) of an Asset Sale of the Stock
Collateral, the Company shall, purchase (i) first, all Senior Notes tendered
pursuant to such Asset Sale Offer in an aggregate principal amount equal to the
portion of such Excess Proceeds resulting from such Asset Sale of Stock
Collateral and (ii) second, all Senior Notes and 13% Notes on a pro rata basis
(in the same manner as described above) in an aggregate principal amount (or,
with respect to 13% Notes prior to April 15, 2001, an aggregate Accreted Value)
equal to the Excess Proceeds not used to purchase Senior Notes pursuant to
clause (i) of this proviso. To the extent that the aggregate principal amount
thereof, plus accrued and unpaid interest to the date of repurchase (or in the
case of repurchases of 13% Notes prior to April 15, 2001, the Accreted Value
thereof as of the date of repurchase) of the Senior Notes (and the 13% Notes)
tendered pursuant to an Asset Sale Offer is less than the Excess Proceeds, the
Company may use such remaining Excess Proceeds for any purpose not prohibited by
this Indenture. If the aggregate principal amount thereof, plus accrued and
unpaid interest to the date of repurchase, (or in the case of repurchases of 13%
Notes prior to April 15, 2001, the Accreted Value thereof as of the date of
repurchase) of Senior Notes and the 13% Notes surrendered by Holders thereof
exceeds the amount of Excess Proceeds, the Trustee shall select the Senior Notes
and the 13% Notes to be purchased on a pro rata basis. Upon completion of such
offer, the amount of Excess Proceeds shall be reset at zero. Pending application
of the Net Cash Proceeds as set forth above from Asset Sales, all such Net Cash
Proceeds shall be placed in escrow for the benefit of the Holders of Senior
Notes.

           Notwithstanding the foregoing, the Company shall not, and shall not
permit any Subsidiary to, directly or indirectly, make any Asset Sale of any
Equity Interests of any Subsidiary (at least 80% of the voting power of the
Capital Stock of which is owned by the Company) except pursuant to an Asset Sale
of all of the Equity Interests of such Subsidiary; provided that any sale of any
Equity Interest of any such Subsidiary to a Strategic Investor shall be deemed
not to be an Asset Sale for purposes of this Section 4.10, so long as such sale
of such Equity Interests does not result in such Subsidiary ceasing to be a
Subsidiary of the Company.

SECTION 4.11. TRANSACTIONS WITH AFFILIATES.

           The Company shall not, and shall not permit any of its Subsidiaries
to, make any payment to, or sell, lease, transfer or otherwise dispose of any of
its properties or assets to, or purchase any property or assets from, or enter
into or make or amend any contract, agreement, understanding, loan, advance or
guarantee with, or for the benefit of, any Affiliate (each of the foregoing, an
"Affiliate Transaction"), unless

           (i) such Affiliate Transaction is on terms that are no less favorable
      to the Company or the relevant Subsidiary, other than those that would
      have been obtained in a comparable transaction by the Company or such
      Subsidiary with an unrelated Person; and

           (ii) the Company delivers to the Trustee (a) with respect to any
      Affiliate Transaction or series of related Affiliate Transactions
      involving aggregate consideration in excess of $1.0 million, a resolution
      adopted by a majority of the disinterested members of the Board of
      Directors and a majority of the Independent Directors of the Company set
      forth in an Officers' Certificate certifying that such Affiliate
      Transaction complies with clause (i) above; and (b) with respect to any
      Affiliate Transaction or series of related Affiliate Transactions
      involving aggregate consideration in excess of $10.0 million, an opinion
      as to the fairness to the Holders of Senior Notes of such Affiliate
      Transaction from a financial point of view issued by a nationally
      recognized consulting firm, business valuation firm or investment banking
      firm;

provided that: (i) all agreements and arrangements with Affiliates, including
without limitation the Local Partner Agreements, the Fiber Lease Agreements, the
Management Agreements, network monitoring agreements and transactions in
connection therewith or pursuant thereto existing on the date of the 13% Note
Indenture and through the current term thereof; (ii) all arrangements and
transactions with Adelphia, including existing intercompany Indebtedness,
overhead charges made in the ordinary course of business, fiber lease
arrangements and similar services existing on the date the 13% Note Indenture
and through the current term thereof; (iii) all employment arrangements approved
by the Board of Directors; (iv) all restricted Payments made pursuant to Section
4.07 hereof; (v) transactions between or among the Company and/or its Wholly
Owned Subsidiaries; (vi) transactions between a General Partner Subsidiary and
the Restricted Joint Venture of which such General Partner Subsidiary is a
general partner; and (vii) management and network monitoring agreements between
the Company and any of its Joint Ventures, shall not be deemed Affiliate
Transactions.

SECTION 4.12. LIENS.

           The Company shall not, and shall not permit any of its Subsidiaries
or Permitted Joint Ventures to, directly or indirectly, create, incur, assume or
suffer to exist any Lien on any asset now owned or hereafter acquired, or any
income or profits therefrom or assign or convey any right to receive income
therefrom, except Permitted Liens.


SECTION 4.13. LINE OF BUSINESS.

           The Company shall not, and shall not permit any of its Subsidiaries
to, engage in any business other than Telecommunications Business and such
business activities as are incidental or related thereto.



                                                       49

SECTION 4.14. CORPORATE EXISTENCE.

           Subject to Article 5 hereof, the Company shall do or cause to be done
all things necessary to preserve and keep in full force and effect (i) its
corporate existence, and the corporate, partnership or other existence of each
of its Subsidiaries, in accordance with the respective organizational documents
(as the same may be amended from time to time) of the Company or any such
Subsidiary and (ii) the rights (charter and statutory), licenses and franchises
of the Company and its Subsidiaries; provided, that the Company shall not be
required to preserve any such right, license or franchise, or the corporate,
partnership or other existence of any of its Subsidiaries, if the Board of
Directors shall determine that the preservation thereof is no longer desirable
in the conduct of the business of the Company and its Subsidiaries, taken as a
whole, and that the loss thereof is not adverse in any material respect to the
Holders of the Senior Notes.


SECTION 4.15. OFFER TO PURCHASE UPON CHANGE OF CONTROL.

           (a) Upon the occurrence of a Change of Control, the Company shall
make an offer (the "Change of Control Offer") to each holder of Senior Notes to
repurchase all or any part (equal to $1,000 or an integral multiple thereof) of
such Holder's Senior Notes at a purchase price equal to 101% of the aggregate
principal amount thereof plus accrued and unpaid interest to the date of
repurchase in accordance with the procedures set forth in this Section 4.15 (the
"Change of Control Payment"). Within ten days following any Change of Control,
the Company shall mail a notice to each Holder stating: (1) that the Change of
Control Offer is being made pursuant to this Section 4.15 and that all Senior
Notes tendered will be accepted for payment; (2) the purchase price and the
purchase date, which shall be no later than 30 business days from the date such
notice is mailed (the "Change of Control Payment Date"); (3) that any Senior
Note not tendered will continue to accrete or accrue interest; (4) that, unless
the Company defaults in the payment of the Change of Control Payment, all Senior
Notes accepted for payment pursuant to the Change of Control Offer shall cease
to accrete or accrue interest after the Change of Control Payment Date; (5) that
Holders electing to have any Senior Notes purchased pursuant to a Change of
Control Offer will be required to surrender the Senior Notes, with the form
entitled "Option of Holder to Elect Purchase" on the reverse of the Senior Notes
completed, to the Paying Agent at the address specified in the notice prior to
the close of business on the third Business Day preceding the Change of Control
Payment Date; (6) that Holders will be entitled to withdraw their election if
the Paying Agent receives, not later than the close of business on the second
Business Day preceding the Change of Control Payment Date, a telegram, telex,
facsimile transmission or letter setting forth the name of the Holder, the
principal amount of Senior Notes delivered for purchase, and a statement that
such Holder is withdrawing his election to have the Senior Notes purchased; and
(7) that Holders whose Senior Notes are being purchased only in part will be
issued new Senior Notes equal in principal amount to the unpurchased portion of
the Senior Notes surrendered, which unpurchased portion must be equal to $1,000
in principal amount or an integral multiple thereof. The Company shall comply
with the requirements of Rule 14e-1 under the Exchange Act and any other
securities laws and regulations thereunder to the extent such laws and
regulations are applicable in connection with the repurchase of Senior Notes as
a result of a Change of Control.

           (b) On the Change of Control Payment Date, the Company shall, to the
extent lawful, (1) accept for payment all Senior Notes or portions thereof
properly tendered pursuant to the Change of Control Offer, (2) deposit with the
Paying Agent an amount equal to the Change of Control Payment in respect of all
Senior Notes or portions thereof so tendered and (3) deliver or cause to be

mail to each Holder of Senior Notes so tendered payment in an amount equal to
the purchase price for the Senior Notes, and the Trustee shall promptly
authenticate and mail (or cause to be transferred by book entry) to each Holder
a new Senior Note equal in principal amount to any unpurchased portion of the
Senior Notes surrendered by such Holder, if any; provided, that each such new
Senior Note shall be in a principal amount of $1,000 or an integral multiple
thereof. The Company shall publicly announce the results of the Change of
Control Offer on or as soon as practicable after the Change of Control Payment
Date.

SECTION 4.16. LIMITATIONS ON SALE AND LEASEBACK TRANSACTIONS.

           of Section 4.09, in the event that the Company fails to comply with
           such section because Indebtedness is deemed to be incurred by a
           Restricted Joint Venture solely as a result of such Restricted Joint
           Venture ceasing to be a Restricted Joint Venture as a result of (i)
           the loss of a Local Partner or (ii) the loss of management control of

           of its Subsidiaries (or the payment of which is guaranteed by the
           Company or any of its Subsidiaries) whether such Indebtedness or
           guarantee now exists, or is created after the date of the Indenture,
           which default (a) is caused by a failure to pay principal of or
           premium, if any, or interest on such Indebtedness prior to the
           expiration of the grace period provided in such Indebtedness on the
           date of such default (a "Payment Default") or (b) results in the
           acceleration of such Indebtedness prior to its express maturity and,

           Subsidiary and such judgment or judgments are not paid within,
           discharged by or stayed for a period of 60 days; provided that the
           aggregate of all such undischarged, unpaid or unstayed judgments
           exceeds $5.0 million;


                (h) any breach or default by the Company in the performance of
           any covenant set forth in the Collateral Agreements which breach or
           default continues for 30 days, or any repudiation by the Company of
           its obligations under any of the Collateral Agreements or the
           unenforceability of any of the Collateral Agreements, for any reason;
           provided that any failure by the Company to comply with the
           provisions of Section 1A of the Pledge Agreement shall not be deemed
           to be a default under this clause (h) so long as, in the event of
           such failure to comply, the Company complies with its obligations
           under Section 10.08 hereof;

                (i) the Company or any of its Significant Subsidiaries or any of
           its Joint Ventures that would, if it were a Subsidiary constitute a

                Significant Subsidiary, or any group of Subsidiaries or Joint
                Ventures that, taken as a whole, would constitute a Significant

                      (ii) appoints a Custodian of the Company or any of its
                Significant Subsidiaries or any of its Joint Ventures that

                Subsidiary, or any group of Subsidiaries or Joint Ventures that,
                taken as a whole, would constitute a Significant Subsidiary or
                for all or substantially all of the property of the Company or
                any of its Significant Subsidiaries or any of its Joint Ventures
                that would, if it were a Subsidiary constitute a Significant
                Subsidiary, or any group of Subsidiaries or Joint Ventures that,
                taken as a whole, would constitute a Significant Subsidiary; or

                      (iii) orders the liquidation of the Company or any of its

           and the order or decree remains unstayed and in effect for 60
           consecutive days.


SECTION 6.02. ACCELERATION.

           If any Event of Default (other than an Event of Default specified in
clause (i) or (j) of Section 6.01 hereof with respect to the Company, any
Significant Subsidiary or any of its Joint Ventures that would, if it were a
Subsidiary constitute a Significant Subsidiary, or any group of Subsidiaries or
Joint Ventures that, taken as a whole, would constitute a Significant
Subsidiary) occurs and is continuing, the Trustee or the Holders of at least 25%
in principal amount of the then outstanding Senior Notes may declare all the
Senior Notes to be due and payable immediately; upon any such declaration, the
Senior Notes shall become due and payable immediately. Notwithstanding the
foregoing, if an Event of Default specified in clause (h) or (i) of Section 6.01
hereof occurs with respect to the Company, any of its Significant Subsidiaries
or any of its Joint Ventures that would, if it were a Subsidiary constitute a
Significant Subsidiary, or any group of Subsidiaries or Joint Ventures that,
taken as a whole, would constitute a Significant Subsidiary, all outstanding
Senior Notes shall be due and payable immediately without further action or
notice. Holders of the Senior Notes may not enforce this Indenture or the Senior
Notes except as provided in this Indenture. The Holders of a majority in
aggregate principal amount of the then outstanding Senior Notes by written
notice to the Trustee may on behalf of all of the Holders rescind an
acceleration and its consequences if the rescission would not conflict with any
judgment or decree and if all existing Events of Default (except nonpayment of
principal, interest or premium that has become due solely because of the
acceleration) have been cured or waived.


                                                       55



<PAGE>




           In the case of any Event of Default occurring by reason of any
willful action (or inaction) taken (or not taken) by or on behalf of the Company
with the intention of avoiding payment of the premium that the Company would
have had to pay if the Company then had elected to redeem the Senior Notes
pursuant to Section 3.07 hereof, an equivalent premium shall also become and be
immediately due and payable to the extent permitted by law upon the acceleration
of the Senior Notes. If an Event of Default occurs prior to August 31, 2001 by
reason of any willful action (or inaction) taken (or not taken) by or on behalf
of the Company with the intention of avoiding the prohibition of redemption of
the Senior Notes prior to August 31, 2001, then the premium payable for purposes
of this paragraph for the period beginning of the date hereof and ending on
August 31, 2001 shall be 106.125% of the amount that would otherwise be due but
for the provisions of this paragraph, plus accrued interest, if any, to the date
of payment.

           The Company is required to deliver to the Trustee annually a
statement regarding compliance with the Indenture, and the Company is required
upon becoming aware of any Default or Event of Default, to deliver to the
Trustee a statement specifying such Default or Event of Default.

SECTION 6.03. OTHER REMEDIES.

           If an Event of Default occurs and is continuing, the Trustee may
pursue any available remedy to collect the payment of principal, premium, if
any, and interest on the Senior Notes or to enforce the performance of any
provision of the Senior Notes, this Indenture, the Escrow and Disbursement
Agreement or the Pledge Agreement.

           The Trustee may maintain a proceeding even if it does not possess any
of the Senior Notes or does not produce any of them in the proceeding. A delay
or omission by the Trustee or any Holder of a Senior Note in exercising any
right or remedy accruing upon an Event of Default shall not impair the right or
remedy or constitute a waiver of or acquiescence in the Event of Default. All
remedies are cumulative to the extent permitted by law.

SECTION 6.04. WAIVER OF PAST DEFAULTS.

           Holders of not less than a majority in aggregate principal amount of
the then outstanding Senior Notes by notice to the Trustee may on behalf of the
Holders of all of the Senior Notes waive an existing Default or Event of Default
and its consequences hereunder, except a continuing Default or Event of Default
in the payment of the principal of, premium and Liquidated Damages, if any, or
interest on, the Senior Notes (including in connection with an offer to
purchase) (provided, however, that the Holders of a majority in aggregate
principal amount of the then outstanding Senior Notes may rescind an
acceleration and its consequences, including any related payment default that
resulted from such acceleration in accordance with Section 6.02 hereof). Upon
any such waiver, such Default shall cease to exist, and any Event of Default
arising therefrom shall be deemed to have been cured for every purpose of this
Indenture; but no such waiver shall extend to any subsequent or other Default or
impair any right consequent thereon.

SECTION 6.05. CONTROL BY MAJORITY.

           Holders of a majority in principal amount of the then outstanding
Senior Notes may direct the time, method and place of conducting any proceeding
for exercising any remedy available to the Trustee or exercising any trust or
power conferred on it, including, without limitation, the exercise of any remedy
under the Collateral Documents. However, the Trustee may refuse to follow any
direction that conflicts with law or this Indenture that the Trustee determines
may be unduly prejudicial to the rights of other Holders of Senior Notes or that
may involve the Trustee in personal liability.

SECTION 6.06. LIMITATION ON SUITS.

           A Holder of a Senior Note may pursue a remedy with respect to this
Indenture or the Senior Notes only if:

           (a)  the Holder of a Senior Note gives to the Trustee written notice
of a continuing Event of Default;

           (b) the Holders of at least 25% in principal amount of the then
      outstanding Senior Notes make a written request to the Trustee to pursue
      the remedy;

           (c) such Holder of a Senior Note or Holders of Senior Notes offer
      and, if requested, provide to the Trustee indemnity satisfactory to the
      Trustee against any loss, liability or expense;

           (d) the Trustee does not comply with the request within 60 days after
      receipt of the request and the offer and, if requested, the provision of
      indemnity; and

           (e) during such 60-day period the Holders of a majority in principal
      amount of the then outstanding Senior Notes do not give the Trustee a
      direction inconsistent with the request.

A Holder of a Senior Note may not use this Indenture to prejudice the rights of
another Holder of a Senior Note or to obtain a preference or priority over
another Holder of a Senior Note.

SECTION 6.07. RIGHTS OF HOLDERS OF SENIOR NOTES TO RECEIVE PAYMENT.

           Notwithstanding any other provision of this Indenture, the right of
any Holder of a Senior Note to receive payment of principal, premium and
Liquidated Damages, if any, and interest on the Senior Note, on or after the
respective due dates expressed in the Senior Note (including in connection with
an offer to purchase), or to bring suit for the enforcement of any such payment
on or after such respective dates, shall not be impaired or affected without the
consent of such Holder.

SECTION 6.08. COLLECTION SUIT BY TRUSTEE.

           If an Event of Default specified in Section 6.01(a) or (b) occurs and
is continuing, the Trustee is authorized to recover judgment in its own name and
as trustee of an express trust against the Company for the whole amount of
principal of, premium and Liquidated Damages, if any, and interest remaining
unpaid on the Senior Notes and interest on overdue principal and, to the extent
lawful, interest and such further amount as shall be sufficient to cover the
costs and expenses of collection, including the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel.

SECTION 6.09. TRUSTEE MAY FILE PROOFS OF CLAIM.

           The Trustee is authorized to file such proofs of claim and other
papers or documents as may be necessary or advisable in order to have the claims
of the Trustee (including any claim for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel) and the
Holders of the Senior Notes allowed in any judicial proceedings relative to the
Company (or any other obligor upon the Senior Notes), its creditors or its
property and shall be entitled and empowered to collect, receive and distribute
any money or other property payable or deliverable on any such claims and any
custodian in any such judicial proceeding is hereby authorized by each Holder to
make such payments to the Trustee, and in the event that the Trustee shall
consent to the making of such payments directly to the Holders, to pay to the
Trustee any amount due to it for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, and any other
amounts due the Trustee under Section 7.07 hereof. To the extent that the
payment of any such compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel, and any other amounts due the Trustee under
Section 7.07 hereof out of the estate in any such proceeding, shall be denied
for any reason, payment of the same shall be secured by a Lien on, and shall be
paid out of, any and all distributions, dividends, money, securities and other
properties that the Holders may be entitled to receive in such proceeding
whether in liquidation or under any plan of reorgan-

ization or arrangement or otherwise. Nothing herein contained shall be deemed to
authorize the Trustee to authorize or consent to or accept or adopt on behalf of
any Holder any plan of reorganization, arrangement, adjustment or composition
affecting the Senior Notes or the rights of any Holder, or to authorize the
Trustee to vote in respect of the claim of any Holder in any such proceeding.

SECTION 6.10. PRIORITIES.

           If the Trustee collects any money pursuant to this Article, it shall
pay out the money in the following order:

           First:  to the Trustee, its agents and attorneys for amounts due

litigant in the suit of an undertaking to pay the costs of the suit, and the
court in its discretion may assess reasonable costs, including reasonable
attorneys' fees, against any party litigant in the suit, having due regard to
the merits and good faith of the claims or defenses made by the party litigant.

SECTION 7.01. DUTIES OF TRUSTEE.

           (a) If an Event of Default has occurred and is continuing, the
Trustee shall exercise such of the rights and powers vested in it by this
Indenture and the Collateral Documents, and use the same degree of care and
skill in its exercise, as a prudent man would exercise or use under the
circumstances in the conduct of his own affairs.

           (b)  Except during the continuance of an Event of Default:

           (i) the duties of the Trustee shall be determined solely by the
      express provisions of this Indenture and the Collateral Documents and the

      covenants or obligations shall be read into this Indenture against the
      Trustee; and

           (ii) in the absence of bad faith on its part, the Trustee may
      conclusively rely, as to the truth of the statements and the correctness
      of the opinions expressed therein, upon certificates or opinions furnished
      to the Trustee and conforming to the requirements of this Indenture and
      the Collateral Documents. However, the Trustee shall examine the
      certificates and opinions to determine whether or not they conform to the
      requirements of this Indenture.

           (c) The Trustee may not be relieved from liabilities for its own
negligent action, its own negligent failure to act, or its own willful
misconduct, except that:

           (i)  this paragraph does not limit the effect of paragraph (b) of
      this Section;

           (ii) the Trustee shall not be liable for any error of judgment made
      in good faith by a Responsible Officer, unless it is proved that the
      Trustee was negligent in ascertaining the pertinent facts; and

           (iii) the Trustee shall not be liable with respect to any action it
      takes or omits to take in good faith in accordance with a direction
      received by it pursuant to Section 6.05 hereof.

           (d) Whether or not therein expressly so provided, every provision of
this Indenture that in any way relates to the Trustee is subject to paragraphs
(a), (b) and (c) of this Section.

           (e) No provision of this Indenture shall require the Trustee to
expend or risk its own funds or incur any liability. The Trustee shall be under
no obligation to exercise any of its rights and powers under this Indenture at
the request of any Holders, unless such Holder shall have offered to the Trustee
security and indemnity satisfactory to it against any loss, liability or
expense.

           (f) The Trustee shall not be liable for interest on any money
received by it except as the Trustee may agree in writing with the Company.

Trustee need not investigate any fact or matter stated in the document.

           (b) Before the Trustee acts or refrains from acting, it may require
an Officers' Certificate or an Opinion of Counsel or both. The Trustee shall not
be liable for any action it takes or omits to take in good faith in reliance on
such Officers' Certificate or Opinion of Counsel. The Trustee may consult with
counsel and the written advice of such counsel or any Opinion of Counsel shall
be full and complete authorization and protection from liability in respect of
any action taken, suffered or omitted by it hereunder in good faith and in
reliance thereon.

due care.

           (d) The Trustee shall not be liable for any action it takes or omits
to take in good faith that it believes to be authorized or within the rights or
powers conferred upon it by this Indenture.

demand, request, direction or notice from the Company shall be sufficient if
signed by an Officer of the Company.

           (f) The Trustee shall be under no obligation to exercise any of the
rights or powers vested in it by this Indenture at the request or direction of
any of the Holders unless such Holders shall have offered to the Trustee
reasonable security or indemnity against the costs, expenses and liabilities
that might be incurred by it in compliance with such request or direction.

SECTION 7.03. INDIVIDUAL RIGHTS OF TRUSTEE.

           The Trustee in its individual or any other capacity may become the
owner or pledgee of Senior Notes and may otherwise deal with the Company or any
Affiliate of the Company with the same rights it would have if it were not
Trustee. However, in the event that the Trustee acquires any conflicting
interest it must eliminate such conflict within 90 days, apply to the SEC for
permission to continue as trustee or resign. Any Agent may do the same with like
rights and duties. The Trustee is also subject to Sections 7.10 and 7.11 hereof.

           If a Default or Event of Default occurs and is continuing and if it

notice of the Default or Event of Default within 90 days after it occurs. Except
in the case of a Default or Event of Default in payment of principal of,
premium, if any, or interest on any Senior Note, the Trustee may withhold the
notice if and so long as a committee of its Responsible Officers in good faith
determines that withholding the notice is in the interests of the Holders of the
Senior Notes.

SECTION 7.06. REPORTS BY TRUSTEE TO HOLDERS OF THE SENIOR NOTES.

           Within 60 days after each May 15 beginning with the May 15 following
the date of this Indenture, and for so long as Senior Notes remain outstanding,
the Trustee shall mail to the Holders of the Senior Notes a brief report dated
as of such reporting date that complies with TIA ' 313(a) (but if no event
described in TIA ' 313(a) has occurred within the twelve months preceding the
reporting date, no report need be transmitted). The Trustee also shall comply
with TIA ' 313(b)(2). The Trustee shall also transmit by mail all reports as
required by TIA ' 313(c).

           A copy of each report at the time of its mailing to the Holders of
Senior Notes shall be mailed to the Company and filed with the SEC and each

313(d). The Company shall promptly notify the Trustee when the Senior Notes are
listed on any stock exchange.

SECTION 7.07. COMPENSATION AND INDEMNITY.

           The Company shall pay to the Trustee from time to time reasonable
compensation for its acceptance of this Indenture and services hereunder. To the
extent permitted by law, the Trustee's compensa-

tion shall not be limited by any law on compensation of a trustee of an express
trust. The Company shall reimburse the Trustee promptly upon request for all
reasonable disbursements, advances and expenses incurred or made by it in
addition to the compensation for its services. Such expenses shall include the
reasonable compensation, disbursements and expenses of the Trustee's agents and
counsel.

           The Company shall indemnify the Trustee against any and all losses,
liabilities or expenses incurred by it arising out of or in connection with the
acceptance or administration of its duties under this Indenture, including the
costs and expenses of enforcing this Indenture, the Collateral Documents or the

Escrow and Disbursement Agreement against the Company (including this Section
7.07) and defending itself against any claim (whether asserted by the Company or
any Holder or any other person) or liability in connection with the exercise or
performance of any of its powers or duties hereunder or under the Collateral
Documents or the Escrow and Disbursement Agreement except to the extent any such
loss, liability or expense may be attributable to its negligence or bad faith.
The Trustee shall notify the Company promptly of any claim for which it may seek
indemnity. Failure by the Trustee to so notify the Company shall not relieve the
Company of its obligations hereunder. The Company shall defend the claim and the
Trustee shall cooperate in the defense. The Trustee may have separate counsel

Company need not pay for any settlement made without its consent, which consent
shall not be unreasonably withheld.

           To secure the Company's payment obligations in this Section, the
Trustee shall have a Lien prior to the Senior Notes on all money or property
held or collected by the Trustee, except that held in trust to pay principal and
interest on particular Senior Notes. Such Lien shall survive the satisfaction
and discharge of this Indenture.

           When the Trustee incurs expenses or renders services after an Event
of Default specified in Section 6.01(g) or (h) hereof occurs, the expenses and
the compensation for the services (including the fees and expenses of its agents
and counsel) are intended to constitute expenses of administration under any
Bankruptcy Law.

           The Trustee shall comply with the provisions of TIA ' 313(b)(2) to
the extent applicable.

SECTION 7.08. REPLACEMENT OF TRUSTEE.

successor Trustee shall become effective only upon the successor Trustee's
acceptance of appointment as provided in this Section.

           The Trustee may resign in writing at any time and be discharged from
the trust hereby created by so notifying the Company. The Holders of Senior
Notes of a majority in principal amount of the then outstanding Senior Notes may

      for relief is entered with respectto the Trustee under any Bankruptcy Law;

           (c)  a Custodian or public officer takes charge of the Trustee or its
      property; or

           (d)  the Trustee becomes incapable of acting.

office of Trustee for any reason, the Company shall promptly appoint a successor
Trustee. Within one year after the successor Trustee takes

office, the Holders of a majority in principal amount of the then outstanding
Senior Notes may appoint a successor Trustee to replace the successor Trustee
appointed by the Company.

           If a successor Trustee does not take office within 60 days after the
retiring Trustee resigns or is removed, the retiring Trustee, the Company, or
the Holders of Senior Notes of at least 10% in principal amount of the then
outstanding Senior Notes may petition any court of competent jurisdiction for
the appointment of a successor Trustee.

           If the Trustee, after written request by any Holder of a Senior Note
who has been a Holder of a Senior Note for at least six months, fails to comply
with Section 7.10, such Holder of a Senior Note may petition any court of
competent jurisdiction for the removal of the Trustee and the appointment of a
successor Trustee.

           A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Company. Thereupon, the
resignation or removal of the retiring Trustee shall become effective, and the
successor Trustee shall have all the rights, powers and the duties of the
Trustee under this Indenture. The successor Trustee shall mail a notice of its
succession to the Holders of the Senior Notes. The retiring Trustee shall
promptly transfer all property held by it as Trustee to the successor Trustee,
provided that all sums owing to the Trustee hereunder have been paid and subject
to the Lien provided for in Section 7.07 hereof. Notwithstanding replacement of
the Trustee pursuant to this Section 7.08, the Company's obligations under
Section 7.07 hereof shall continue for the benefit of the retiring Trustee.

SECTION 7.09. SUCCESSOR TRUSTEE BY MERGER, ETC.

           If the Trustee consolidates, merges or converts into, or transfers
all or substantially all of its corporate trust business to, another
corporation, the successor corporation without any further act shall be the
successor Trustee.

SECTION 7.10. ELIGIBILITY; DISQUALIFICATION.

           There shall at all times be a Trustee hereunder that is a corporation
organized and doing business under the laws of the United States of America or
of any state thereof that is authorized under such laws to exercise corporate
trustee power, that is subject to supervision or examination by federal or state
authorities. The Trustee and its direct parent shall at all times have a
combined capital surplus of at least fifty million dollars. If such corporation
publishes reports of condition at least annually, pursuant to law or to the
requirements of the aforesaid supervising or examining authority, then for
purposes of this Section 7.10 the combined capital and surplus of such
corporation shall be deemed to be its combined capital and surplus as set forth
in its most recent report of condition so published.

           This Indenture shall always have a Trustee who satisfies the
requirements of TIA ' 310(a)(1), (2) and (5). The Trustee is subject to TIA '
310(b).

SECTION 7.11. PREFERENTIAL COLLECTION OF CLAIMS AGAINST THE COMPANY.

           The Trustee is subject to TIA ' 311(a), excluding any creditor
relationship listed in TIA ' 311(b). A Trustee who has resigned or been removed
shall be subject to TIA ' 311(a) to the extent indicated therein.

SECTION 8.01. OPTION TO EFFECT LEGAL DEFEASANCE OR COVENANT DEFEASANCE.

           The Company may, at the option of its Board of Directors evidenced by
a resolution set forth in an Officers' Certificate, at any time, elect to have
either Section 8.02 or 8.03 hereof be applied to all outstanding Senior Notes
upon compliance with the conditions set forth below in this Article Eight.

SECTION 8.02. LEGAL DEFEASANCE AND DISCHARGE.

           Upon the Company's exercise under Section 8.01 hereof of the option

of the conditions set forth in Section 8.04 hereof, be deemed to have been
discharged from its obligations with respect to all outstanding Senior Notes on
the date the conditions set forth below are satisfied (hereinafter, "Legal
Defeasance"). For this purpose, Legal Defeasance means that the Company shall be
deemed to have paid and discharged the entire Indebtedness represented by the
outstanding Senior Notes, which shall thereafter be deemed to be "outstanding"
only for the purposes of Section 8.05 hereof and the other Sections of this
Indenture referred to in (a) and (b) below, and to have satisfied all its other
obligations under such Senior Notes and this Indenture (and the Trustee, on
demand of and at the expense of the Company, shall execute proper instruments
acknowledging the same), except for the following provisions which shall survive
until otherwise terminated or discharged hereunder: (a) the rights of Holders of
outstanding Senior Notes to receive payments in respect of the principal of,
premium, if any, and interest on such Senior Notes when such payments are due,
(b) the Company's obligations with respect to such Senior Notes under Article 2
and Section 4.02 hereof, (c) the rights, powers, trusts, duties and immunities
of the Trustee hereunder and the Company's obligations in connection therewith
and (d) this Article Eight. Subject to compliance with this Article Eight, the

           Upon the Company's exercise under Section 8.01 hereof of the option
applicable to this Section 8.03, the Company shall, subject to the satisfaction
of the conditions set forth in Section 8.04 hereof, be released from its
obligations under the covenants contained in Sections 4.07, 4.08, 4.09, 4.10,
4.11, 4.12, 4.13, 4.15, 4.16 and 4.17 hereof with respect to the outstanding
Senior Notes on and after the date the conditions set forth below are satisfied
(hereinafter, "Covenant Defeasance"), and the Senior Notes shall thereafter be
deemed not "outstanding" for the purposes of any direction, waiver, consent or
declaration or act of Holders (and the consequences of any thereof) in
connection with such covenants, but shall continue to be deemed "outstanding"
for all other purposes hereunder (it being understood that such Senior Notes
shall not be deemed outstanding for accounting purposes). For this purpose,
Covenant Defeasance means that, with respect to the outstanding Senior Notes,
the Company may omit to comply with and shall have no liability in respect of
any term, condition or limitation set forth in any such covenant, whether
directly or indirectly, by reason of any reference elsewhere herein to any such
covenant or by reason of any reference in any such covenant to any other
provision herein or in any other document and such omission to comply shall not
constitute a Default or an Event of Default under Section 6.01 hereof, but,
except as specified above, the remainder of this Indenture and such Senior Notes
shall be unaffected thereby. In addition, upon


                                                       64

this Section 8.03 hereof, subject to the satisfaction of the conditions set
forth in Section 8.04 hereof, Sections 6.01(d) through 6.01(g) hereof shall not

applicable federal income tax law, in either case to the effect that, and based

outstanding Senior Notes will not recognize income, gain or loss for federal
income tax purposes as a result of such Legal Defeasance and will be subject to
federal income tax on the same amounts, in the same manner and at the same time

hereof are concerned, at any time in the period ending on the 91st day after the
date of deposit;

           (e) such Legal Defeasance or Covenant Defeasance will not result in a
breach or violation of, or constitute a default under any material agreement or
instrument (other than this Indenture) to which the Company or any of its
Subsidiaries is a party or by which the Company or any of its subsidiaries is
bound;

           (f) the Company shall have delivered to the Trustee an opinion of

<PAGE>



bankruptcy, insolvency, reorganization or similar laws affecting creditors'
rights generally;

           (h) the Company shall have delivered to the Trustee an Officers'
Certificate and an opinion of counsel, each stating that all conditions
precedent provided for relating to the Legal Defeasance or the Covenant

SECTION 8.05. DEPOSITED MONEY AND GOVERNMENT SECURITIES TO BE HELD IN TRUST;
                      OTHER MISCELLANEOUS PROVISIONS.

           Subject to Section 8.06 hereof, all money and non-callable U.S.

Trustee shall deliver or pay to the Company from time to time upon the request
of the Company any money or non-callable U.S. Government Obligations held by it
as provided in Section 8.04 hereof which, in the opinion of a nationally
recognized firm of independent public accountants expressed in a written
certification thereof delivered to the Trustee (which may be the opinion
delivered under Section 8.04(a) hereof), are in excess of the amount thereof
that would then be required to be deposited to effect an equivalent Legal
Defeasance or Covenant Defeasance.

SECTION 8.06. REPAYMENT TO THE COMPANY.

           Any money deposited with the Trustee or any Paying Agent, or then

such principal, and premium, if any, or interest or Liquidated Damages, if any,
has become due and payable shall be paid to the Company on its request or (if
then held by the Company) shall be discharged from such trust; and the Holder of
such Senior Note shall thereafter, as a secured creditor, look only to the
Company for payment thereof, and all liability of the Trustee or such Paying
Agent with respect to such trust money, and all liability of the Company as

           If the Trustee or Paying Agent is unable to apply any United States
dollars or non-callable Government Securities in accordance with Section 8.02 or
8.03 hereof, as the case may be, by reason of any order or judgment of any court
or governmental authority enjoining, restraining or otherwise prohibiting such
application, then the Company's obligations under this Indenture and the Senior
Notes shall be revived and reinstated as though no deposit had occurred pursuant
to Section 8.02 or 8.03 hereof until such time as the Trustee or Paying Agent is
permitted to apply all such money in accordance with Section 8.02 or 8.03

payment of principal of, premium, if any, or interest or Liquidated Damages, if
any, on any Senior Note following the reinstatement of its obligations, the
Company shall be subrogated to the rights of the Holders of such Senior Notes to
receive such payment from the money held by the Trustee or Paying Agent.

           (d) to make any change that would provide any additional rights or
      benefits to the Holders of the Senior Notes or that does not adversely
      affect the legal rights hereunder of any Holder of the Senior Note; or

           (e) to comply with requirements of the SEC in order to effect or
      maintain the qualification of this Indenture under the TIA.

           (f)  to enter into additional or supplemental Collateral Documents.

           Upon the request of the Company accompanied by a resolution of its
Board of Directors authorizing the execution of any such amended or supplemental
Indenture or Collateral Documents, and upon receipt by the Trustee of the
documents described in Section 9.06 hereof, the Trustee shall join with the
Company in the execution of any amended or supplemental Indenture or Collateral
Documents authorized or permitted by the terms of this Indenture and to make any
further appropriate agreements and stipulations that may be therein contained,
but the Trustee shall not be obligated to enter into such amended or
supplemental Indenture that affects its own rights, duties or immunities under
this Indenture or otherwise.

SECTION 9.02. WITH CONSENT OF HOLDERS OF SENIOR NOTES.

           Except as provided below in this Section 9.02, the Company and the
Trustee may amend or supplement this Indenture, the Collateral Documents and the
Senior Notes may be amended or supplemented with the consent of the Holders of
at least a majority in principal amount of the Senior Notes then outstanding
(including consents obtained in connection with a purchase of or a tender offer
or exchange offer for the Senior Notes), and, subject to Sections 6.04 and 6.07
hereof, any existing Default or Event of Default (other than a Default or Event
of Default in the payment of the principal of, premium, if any, or interest on
the Senior Notes, except a payment default resulting from an acceleration that
has been rescinded) or compliance with any provision of this Indenture, the
Collateral Documents or the Senior Notes may be waived with the consent of the
Holders of a majority in aggregate principal amount of the then outstanding
Senior Notes (including consents obtained in connection with a purchase of or a
tender offer or exchange offer for the Senior Notes).

           Upon the request of the Company accompanied by a resolution of its
Board of Directors authorizing the execution of any such amended or supplemental
Indenture, and upon the filing with the Trustee of evidence satisfactory to the
Trustee of the consent of the Holders of Senior Notes as aforesaid, and upon
receipt by the Trustee of the documents described in Section 9.06 hereof, the
Trustee shall join with the Company in the execution of such amended or
supplemental Indenture unless such amended or supplemental Indenture affects the
Trustee's own rights, duties or immunities under this Indenture or otherwise, in
which case the Trustee may in its discretion, but shall not be obligated to,
enter into such amended or supplemental Indenture.

           It shall not be necessary for the consent of the Holders of Senior
Notes under this Section 9.02 to approve the particular form of any proposed
amendment or waiver, but it shall be sufficient if such consent approves the
substance thereof.

           After an amendment, supplement or waiver under this Section becomes
effective, the Company shall mail to the Holders of each Senior Note affected
thereby a notice briefly describing the amendment, supplement or waiver. Any
failure of the Company to mail such notice, or any defect therein, shall not,


                                                       68

however, in any way impair or affect the validity of any such amended or
supplemental Indenture or waiver. Subject to Sections 6.04 and 6.07 hereof, the
Holders of a majority in aggregate principal amount of the Senior Notes then
outstanding may waive compliance in a particular instance by the Company with
any provision of this Indenture, the Collateral Agreements or the Senior Notes.
However, without the consent of each Holder affected, an amendment, supplement
or waiver may not (with respect to any Senior Notes held by a non-consenting
Holder):

                (a) reduce the principal amount of Senior Notes whose Holders
          must consent to an amendment, supplement or waiver;

                (b) reduce the principal of or change the fixed maturity of any
           Senior Note or alter or waive any of the provisions with respect to
           the redemption of the Senior Notes except as provided in clause (g)
           below with respect to Sections 3.09, 4.10 and 4.15 hereof;

                (c) reduce the rate of or change the time for payment of
          interest, including default interest, on any Senior Note;

                (d) waive a Default or Event of Default in the payment of
           principal of or premium, if any, or interest on the Senior Notes
           (except a rescission of acceleration of the Senior Notes by the
           Holders of at least a majority in aggregate principal amount of the
           then outstanding Senior Notes and a waiver of the payment default
           that resulted from such acceleration);

                (e) make any Senior Note payable in money other than that stated
           in the Senior Notes;

                (f) make any change in the provisions of this Indenture relating
           to waivers of past Defaults or the rights of Holders of Senior Notes
           to receive payments of principal of or premium, if any, or interest
           on the Senior Notes;

                (g) waive a redemption payment with respect to any Senior Note
           (other than a payment required by Sections 3.09, 4.10 and 4.15
           hereof);

                (h) make any change in the provisions of this Indenture relating
           to Collateral and Security or the Collateral Agreements that would
           adversely affect the holders of the Senior Notes; or

                (i) make any change in the foregoing amendment and waiver
           provisions.

SECTION 9.03. COMPLIANCE WITH TRUST INDENTURE ACT.

           Every amendment or supplement to this Indenture, the Collateral
Documents or the Senior Notes shall be set forth in a amended or supplemental
Indenture that complies with the TIA as then in effect.

SECTION 9.04. REVOCATION AND EFFECT OF CONSENTS.

           Until an amendment, supplement or waiver becomes effective, a consent
to it by a Holder of a Senior Note is a continuing consent by the Holder and
every subsequent Holder of a Senior Note or portion of a Senior Note that
evidences the same debt as the consenting Holder's Senior Note, even if notation
of the consent is not made on any Senior Note. However, any such Holder or
subsequent Holder of a Senior Note may revoke the consent as to its Senior Note
if the Trustee receives written notice of revocation before the date the waiver,
supplement or amendment becomes effective. An amendment, supplement or waiver
becomes effective in accordance with its terms and thereafter binds every
Holder.

SECTION 9.05. NOTATION ON OR EXCHANGE OF SENIOR NOTES.

           The Trustee may place an appropriate notation about an amendment,
supplement or waiver on any Senior Note thereafter authenticated. The Company in
exchange for all Senior Notes may issue and the Trustee shall authenticate new
Senior Notes that reflect the amendment, supplement or waiver.

           Failure to make the appropriate notation or issue a new Senior Note
shall not affect the validity and effect of such amendment, supplement or
waiver.

SECTION 9.06. TRUSTEE TO SIGN AMENDMENTS, ETC.

           The Trustee shall sign any amended or supplemental Indenture
authorized pursuant to this Article Nine if the amendment or supplement does not
adversely affect the rights, duties, liabilities or immunities of the Trustee.
The Company may not sign an amendment or supplemental Indenture until the Board
of Directors approves it. In executing any amended or supplemental indenture,
the Trustee shall be entitled to receive and (subject to Section 7.01) shall be
fully protected in relying upon, an Officer's Certificate and an Opinion of
Counsel stating that the execution of such amended or supplemental indenture is
authorized or permitted by this Indenture.

as may be required by the provisions of the Pledge Agreement, to assure and

Pledged Collateral contemplated hereby, by the Pledge Agreement or any part
thereof, as from time to time constituted, so as to render the same available
for the security and benefit of this Indenture and of the Senior Notes secured
hereby, according to the intent and purposes herein expressed. The Company shall
take, or shall cause its Subsidiaries and, if necessary, its Joint Ventures to
take, any and all actions reasonably required to cause the Pledge Agreement to
create and maintain, as security for the Obligations of the Company hereunder, a
valid and enforceable perfected first priority Lien in and on all the Pledged
Collateral, in favor of the Collateral Agent for the benefit of the Holders of
Senior Notes, superior to and prior to the rights of all third Persons and
subject to no other Liens than Permitted Liens.

make effective the Lien intended to be created by the Pledge Agreement, and

                                                       71



<PAGE>



Agreement and reciting with respect to the security interests in the Pledged
Collateral the details of such action or referring to prior Opinions of Counsel
in which such details are given, (B) stating that, based on relevant laws as in
effect on the date of such Opinion of Counsel, all financing statements and
continuation statements have been executed and filed that are necessary as of
such date and during the succeeding 12 months fully to preserve and protect, to
the extent such protection and preservation are possible by filing, the rights
of the Holders of Senior Notes and the Collateral Agent and the Trustee
hereunder and under the Pledge Agreement with respect to the security interests
in the Pledged Collateral, or (ii) stating that, in the opinion of such counsel,
no such action is necessary to maintain such Lien and assignment.

SECTION 10.03. RELEASE OF COLLATERAL.

      (a) Subject to subsections (b), (c) and (d) of this Section 10.03, Pledged
Collateral may be released from the Lien and security interest created by the
Pledge Agreement at any time or from time to time in accordance with the
provisions of the Pledge Agreement or as provided hereby. In addition, upon the
request of the Company pursuant to an Officers' Certificate certifying that all
conditions precedent hereunder have been met and stating whether or not such
release is in connection with an Asset Sale and (at the sole cost and expense of
the Company) the Collateral Agent shall release (i) Pledged Collateral that is
sold, conveyed or disposed of in compliance with the provisions of this
Indenture; provided, that if such sale, conveyance or disposition constitutes an
Asset Sale, the Company shall apply the Net Proceeds in accordance with Section
4.10 hereof. Upon receipt of such Officers' Certificate the Collateral Agent
shall execute, deliver or acknowledge any necessary or proper instruments of
termination, satisfaction or release to evidence the release of any Pledged
Collateral permitted to be released pursuant to this Indenture or the Pledge
Agreement.

      (b) No Pledged Collateral shall be released from the Lien and security
interest created by the Pledge Agreement pursuant to the provisions of the
Pledge Agreement unless there shall have been delivered to the Collateral Agent
the certificate required by this Section 10.03.

      (c) At any time when an Event of Default shall have occurred and be
continuing and the maturity of the Senior Notes shall have been accelerated
(whether by declaration or otherwise) and the Trustee shall have delivered a
notice of acceleration to the Collateral Agent, no release of Pledged Collateral
pursuant to the provisions of the Pledge Agreement shall be effective as against
the Holders of Senior Notes.

      (d) The release of any Pledged Collateral from the terms of this Indenture
and the Pledge Agreement shall not be deemed to impair the security under this
Indenture in contravention of the provisions hereof if and to the extent the
Pledged Collateral is released pursuant to the terms of the Pledge Agreement. To
the extent applicable, the Company shall cause TIA ' 313(c), relating to
reports, and TIA ' 314(b), relating to the release of property or securities
from the Lien and security interest of the Pledge Agreement and relating to the
substitution therefor of any property or securities to be subjected to the Lien
and security interest of the Pledge Agreement, to be complied with. The Trustee
shall comply (to the extent required) with TIA ' 313(b)(1) and 313(d). Any
certificate or opinion required by TIA ' 314(d) may be made by an Officer of the
Company except in cases where TIA ' 314(d) requires that such certificate or
opinion be made by an independent Person, which Person shall be an independent
engineer, appraiser or other expert selected or approved by the Trustee and the
Collateral Agent in the exercise of reasonable care.

Agreement or the Escrow and Disbursement Agreement, (i) all documents required
by TIA '314(c) and (d) and (ii) an Opinion of Counsel to the effect that such
accompanying documents constitute all documents required by TIA '314(d). The
Trustee may, to the extent permitted by Sections 7.01 and 7.02 hereof, accept as
conclusive evidence of compliance with the foregoing provisions the appropriate
statements contained in such documents and such Opinion of Counsel.

SECTION 10.05. CERTIFICATES OF THE TRUSTEE.

may, in its sole discretion and without the consent of the Holders of Senior
Notes, direct, on behalf of the Holders of Senior Notes, the Collateral Agent
to, take all actions it deems necessary or appropriate in order to (a) enforce
any of the terms of the Pledge Agreement and (b) collect and receive any and all
amounts payable in respect of the Obligations of the Company hereunder. The
Trustee shall have power to institute and maintain such suits and proceedings as
it may deem expedient to prevent any impairment of the Pledged Collateral by any
acts that may be unlawful or in violation of the Pledge Agreement or this
Indenture, and such suits and proceedings as the Trustee may deem expedient to
preserve or protect its interests and the interests of the Holders of Senior
Notes in the Pledged Collateral (including power to institute and maintain suits
or proceedings to restrain the enforcement of or compliance with any legislative
or other governmental enactment, rule or order that may be unconstitutional or
otherwise invalid if the enforcement of, or compliance with, such enactment,
rule or order would impair the security interest hereunder or be prejudicial to
the interests of the Holders of Senior Notes or of the Trustee).

                      AGREEMENT.

SECTION 11.04. CERTIFICATE AND OPINION AS TO CONDITIONS PRECEDENT.

           Upon any request or application by the Company to the Trustee to take
any action under this Indenture, the Company shall furnish to the Trustee:

           (a) an Officers' Certificate in form and substance reasonably
      satisfactory to the Trustee (which shall include the statements set forth
      in Section 11.05 hereof) stating that, in the opinion of the signers, all
      conditions precedent and covenants, if any, provided for in this Indenture
      relating to the proposed action have been satisfied; and

           (b) an Opinion of Counsel in form and substance reasonably
      satisfactory to the Trustee (which shall include the statements set forth
      in Section 11.05 hereof) stating that, in the opinion of such counsel, all
      such conditions precedent and covenants have been satisfied.

SECTION 11.05. STATEMENTS REQUIRED IN CERTIFICATE OR OPINION.

           Each certificate or opinion with respect to compliance with a
condition or covenant provided for in this Indenture (other than a certificate
provided pursuant to TIA ' 314(a)(4)) shall comply with the provisions of TIA '
314(e) and shall include:

           (a)  a statement that the Person making such certificate or opinion
      has read such covenant or condition;

           (b) a brief statement as to the nature and scope of the examination
      or investigation upon which the statements or opinions contained in such
      certificate or opinion are based;

           (c) a statement that, in the opinion of such Person, he or she has

SECTION 11.06. RULES BY TRUSTEE AND AGENTS.

Company, as such, shall have any liability for any obligations of the Company
under the Senior Notes or the Indenture or for any claim based on, in respect
of, or by reason of, such obligations or their creation. Each Holder of Senior
Notes by accepting a Senior Note waives and releases all such liability. The
waiver and release are part of the consideration for issuance of the Senior
Notes. Such waiver may not be effective to waive liabilities under the federal
securities laws and it is the view of the SEC that such a wavier is against
public policy.

         1. INTEREST. Hyperion Telecommunications, Inc., a Delaware corporation
(the "Company"), promises to pay interest on the principal amount of this Senior
Note at the rate of 12 1/4% per annum from


<PAGE>



August 27, 1997 until maturity (including any additional interest required to be
paid pursuant to the provisions of the Registration Rights Agreement) and will
be payable semi-annually in cash on September 1 and March 1 of each year, or if
any such day is not a Business Day, on the next succeeding Business Day (each an
"Interest Payment Date"); provided that in the event that the Company does not
comply with Section 1A(a) and (b) of the Pledge Agreement, the interest rate on
the Senior Notes will automatically increase by 0.25% per annum (the "Additional
Interest") to 12 1/2% and the Additional Interest shall continue until such time
as the Company complies with its obligations under Section 1A of the Pledge
Agreement, at which time the Additional Interest shall cease. Interest and
Additional Interest, if any, on the Senior Notes will accrue from the most
recent date to which interest has been paid or, if no interest has been paid,
from the date of issuance; provided that if there is no existing Default in the
payment of interest, and if this Senior Note is authenticated between a record
date referred to on the face hereof and the next succeeding Interest Payment
Date, interest shall accrue from such next succeeding Interest Payment Date,
provided, further, that the first Interest Payment Date shall be March 1, 1998.
The Company will pay interest (including post-petition interest in any
proceeding under any Bankruptcy Law) on overdue principal and premium, if any,
from time to time on demand at a rate that is 1% per annum in excess of the rate
then in effect; it will pay interest (including post-petition interest in any
proceeding under any Bankruptcy Law) on overdue installments of interest and
Liquidated Damages (without regard to any applicable grace periods) from time to
time on demand at the same rate to the extent lawful. Interest will be computed
on the basis of a 360-day year comprised of twelve 30-day months.

         2. METHOD OF PAYMENT. The Company will pay interest on the Senior Notes
(except defaulted interest) to the Persons who are registered Holders of Senior
Notes at the close of business on the August 15 or February 15 next preceding
the Interest Payment Date, even if such Senior Notes are cancelled after such
record date and on or before such Interest Payment Date, except as provided in
Section 2.13 of the Indenture with respect to defaulted interest. The Senior
Notes shall be payable as to principal, premium and interest at the office or
agency of the Company maintained for such purpose within or without the City and
State of New York, or, at the option of the Company, payment of interest may be
made by check mailed to the Holders at their addresses set forth in the register
of Holders; provided that payment by wire transfer of immediately available
funds shall be required with respect to principal of, and interest and premium
on, all Global Notes and all other Senior Notes the Holders of which shall have
provided wire transfer instructions to the Company or the Paying Agent. Such
payment shall be in such coin or currency of the United States of America as at
the time of payment is legal tender for payment of public and private debts.

         3. PAYING AGENT AND REGISTRAR. Initially, Bank of Montreal Trust
Company, the Trustee under the Indenture, shall act as Paying Agent and
Registrar. The Company may change any Paying Agent or Registrar without notice
to any Holder. The Company or any of its Subsidiaries may act in any such
capacity.

         4. INDENTURE AND PLEDGE AND SECURITY AGREEMENT. The Company issued the
Senior Notes under an Indenture dated as of August 27, 1997 (the "Indenture")
between the Company and the Trustee. The terms of the Senior Notes include those
stated in the Indenture and those made a part of the Indenture by reference to
the Trust Indenture Act of 1939, as amended (15 U.S. Code " 77aaa-77bbbb) (the
"TIA"). The Senior Notes are subject to all such terms, and Holders are referred
to the Indenture and the TIA for a statement of such terms. The Senior Notes are
senior obligations of the Company limited to $250.0 million in aggregate
principal amount at maturity. The Senior Notes are secured by a pledge of the
Pledged Collateral (as defined in the Indenture) pursuant to the Pledge and
Security Agreement referred to in the Indenture. The Senior Notes are senior
obligations of the Company limited to $250.0 million in aggregate principal
amount at maturity.

      6.  MANDATORY REDEMPTION.

      Except as set forth in paragraph 7 below, the Company shall not be

multiple thereof) of such Holder's Senior Notes at a purchase price equal to
101% of the aggregate principal amount thereof plus accrued and unpaid interest
and Liquidated Damages, if any, to the date of repurchase (the "Change of
Control Payment"). Within ten days following any Change of Control, the Company

                                                      A-4


<PAGE>



interest to the date of repurchase (or, in the case of repurchases of 13% Notes
prior to April 15, 2001, at a purchase price equal to 100% of the Accreted Value
thereof as of the date of repurchase) in accordance with the procedures set

Collateral and (ii) second, all Senior Notes and 13% Notes on a pro rata basis
(in the same manner as described above) in an aggregate principal amount (or,

equal to the Excess Proceeds not used to purchase Senior Notes pursuant to
clause (i) of this proviso. The Senior Notes are in registered form without
coupons in denominations of $1,000 and integral multiples of $1,000. The
transfer of the Senior Notes may be registered and the Senior Notes may be
exchanged as provided in the Indenture. The Registrar and the Trustee may
require a Holder, among other things, to furnish appropriate endorsements and
transfer documents and the Company may require a Holder to pay any taxes and
fees required by law or permitted by the Indenture. The Company need not
exchange or register the transfer of any Senior Note or portion of a Senior Note
selected for redemption, except for the unredeemed portion of any Senior Note
being redeemed in part. Also, it need not exchange or register the transfer of
any Senior Notes for a period of 15 days before a selection of Senior Notes to
be redeemed or during the period between a record date and the corresponding
Interest Payment Date.

      10. PERSONS DEEMED OWNERS. The registered Holder of a Senior Note may be
treated as its owner for all purposes.

      11. AMENDMENT, SUPPLEMENT AND WAIVER. Subject to certain exceptions, the
Indenture or the Senior Notes may be amended or supplemented with the consent of
the Holders of at least a majority in principal amount of the then outstanding
Senior Notes, and any existing default or compliance with any provision of the
Indenture, the Collateral Documents or the Senior Notes may be waived with the
consent of the Holders of a majority in aggregate principal amount of the then
outstanding Senior Notes. Without the consent of any Holder of a Senior Note,
the Indenture, the Collateral Documents or the Senior Notes may be amended or
supplemented to cure any ambiguity, defect or inconsistency, to provide for
uncertificated Senior Notes in addition to or in place of certificated Senior
Notes, to provide for the assumption of the Company's obligations to Holders of
the Senior Notes in case of a merger or consolidation, to make any change that
would provide any additional rights or benefits to the Holders of the Senior
Notes or that does not adversely affect the legal rights under the Indenture of
any such Holder, or to comply with the requirements of the SEC in order to
effect or maintain the qualification of the Indenture under the Trust Indenture
Act.

      12. DEFAULTS AND REMEDIES. Events of Default include: (i) default for 30
days in the payment when due of interest on, or Liquidated Damages with respect
to, the Senior Notes; (ii) default in payment when due of principal of or
premium, if any, on the Senior Notes when the same becomes due and payable at
maturity, upon redemption (including in connection with an offer to purchase) or
otherwise, (iii) failure by the Company to comply with Section 4.07, 4.10, 4.15
or 5.01 of the Indenture; (iv) failure by the Company to comply with Section
4.09 of the Indenture; provided that in the event that the Company fails to
comply with Section 4.09 of the Indenture because indebtedness is deemed to be
incurred by a Restricted Joint Venture solely as a result of such Restricted
Joint Venture ceasing to be a Restricted Joint Venture as a result of (x) the
loss of a Local Partner or (y) the loss of management control of such Restricted
Joint Venture, and such failure continues for 90 days; (v) failure by the
Company for 30 days after notice to the Company by the Trustee or the Holders of
at least 25% in principal amount of the Senior Notes then outstanding to comply
with certain other agreements in the Indenture or the Senior Notes; (vi) default
under certain other agreements relating to Indebtedness of the Company which
default results in the acceleration of such Indebtedness prior to its express
maturity; (vii) certain final judgments for the payment of money that remain
undischarged for a period of 60 days; (viii) any breach or default by the
Company in the performance of any

                                                      A-5


<PAGE>



covenant set forth in the Collateral Agreements which breach or default
continues for 30 days, or any repudiation by the Company of its obligation under
any of the Collateral Agreements or the unenforceability of any of the
Collateral Agreements, for any reason; and (ix) certain events of bankruptcy or
insolvency with respect to the Company or any of its Significant Subsidiaries or
any of its Joint Ventures that would, if it were a Subsidiary, constitute a
Significant Subsidiary. If any Event of Default occurs and is continuing, the
Trustee or the Holders of at least 25% in principal amount of the then
outstanding Senior Notes may declare all the Senior Notes to be due and payable
immediately. Notwithstanding the foregoing, in the case of an Event of Default
arising from certain events of bankruptcy or insolvency with respect to the
Company, any of its Significant Subsidiaries or any Joint Venture that would, if
it were a Subsidiary constitute a Significant Subsidiary, or any group of
Subsidiaries or Joint Ventures that, taken together, would, constitute a
Significant Subsidiary, all outstanding Senior Notes shall become due and
payable without further action or notice. Holders of the Senior Notes may not
enforce the Indenture or the Senior Notes except as provided in the Indenture.
Subject to certain limitations, Holders of a majority in principal amount of the
then outstanding Senior Notes may direct the Trustee in its exercise of any
trust or power. The Trustee may withhold from Holders of the Senior Notes notice
of any continuing Default or Event of Default (except a Default or Event of
Default relating to the payment of principal or interest) if it determines that
withholding notice is in their interest. The Holders of a majority in aggregate
principal amount of the Senior Notes then outstanding by notice to the Trustee
may on behalf of the Holders of all of the Senior Notes waive any existing
Default or Event of Default and its consequences under the Indenture, except a
continuing Default or Event of Default in the payment of interest on, or the
principal of, the Senior Notes. The Company is required to deliver to the
Trustee annually a statement regarding compliance with the Indenture, and the
Company is required upon becoming aware of any Default or Event of Default, to
deliver to the Trustee a statement specifying such Default or Event of Default.

      13. TRUSTEE DEALINGS WITH COMPANY. The Trustee, in its individual or any
other capacity, may make loans to, accept deposits from, and perform services
for the Company or its Affiliates, and may otherwise deal with the Company or
its Affiliates, as if it were not the Trustee.

      14. NO RECOURSE AGAINST OTHERS. A director, officer, employee,
incorporator or stockholder, of the Company, as such, shall not have any
liability for any obligations of the Company under the Senior Notes or the
Indenture or for any claim based on, in respect of, or by reason of, such
obligations or their creation. Each Holder by accepting a Senior Note waives and
releases all such liability. The waiver and release are part of the
consideration for the issuance of the Senior Notes.

      15. AUTHENTICATION. This Senior Note shall not be valid until
authenticated by the manual signature of the Trustee or an authenticating agent.

      16. ABBREVIATIONS. Customary abbreviations may be used in the name of a
Holder or an assignee, such as: TEN COM (= tenants in common), TEN ENT (=
tenants by the entireties), JT TEN (= joint tenants with right of survivorship
and not as tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts
to Minors Act).

      17. ADDITIONAL RIGHTS OF HOLDERS OF TRANSFER RESTRICTED SECURITIES. In
addition to the rights provided to Holders of the Senior Notes under the
Indenture, Holders of Transferred Restricted Securities shall have all the
rights set forth in the Registration Rights Agreement dated as of August 27,
1997, between the Company and the parties named on the signature pages thereof
(the "Registration Rights Agreement").

      18.  CUSIP NUMBERS.  Pursuant to a recommendation promulgated by the
Committee on Uniform Security Identification Procedures, the Company has caused
CUSIP numbers to be printed on the Senior

                                                      A-6

Notes and the Trustee may use CUSIP numbers in notices of redemption as a
convenience to the Holders. No representation is made as to the accuracy of such
numbers either as printed on the Senior Notes or as contained in any notice of
redemption and reliance may be placed only on the other identification numbers
placed thereon.

      The Company shall furnish to any Holder upon written request and without
charge a copy of the Indenture and/or the Registration Rights Agreement.

below unless otherwise indicated.

      1. INTEREST. Hyperion Telecommunications, Inc., a Delaware corporation
(the "Company"), promises to pay interest on the principal amount of this Senior
Note at the rate of 12-1/4% per annum from August 27, 1997 until maturity
(including any additional interest required to be paid pursuant to the
provisions of the Registration Rights Agreement) and will be payable
semi-annually in cash on September 1 and March 1 of each year, or if any such
day is not a Business Day, on the next succeeding Business Day (each an
"Interest Payment Date"); provided that in the event that the Company does not
comply with Section 1A(a) and (b) of the Pledge Agreement, the interest rate on
the Senior Notes will automatically increase by 0.25% per annum (the "Additional
Interest") to 12-1/2% and the Additional Interest shall continue until such time
as the Company complies with its obligations under Section 1A of the Pledge
Agreement, at which time the Additional Interest shall cease. Interest and
Additional Interest, if any, on the Senior Notes will accrue from the most
recent date to which interest has been paid or, if no interest has been paid,
from the date of issuance; provided that if there is no existing Default in the
payment of interest, and if this Senior Note is authenticated between a record
date referred to on the face hereof and the next succeeding Interest Payment
Date, interest shall accrue from such next succeeding Interest Payment Date,
provided, further, that the first Interest Payment Date shall be March 1, 1998.
The Company will pay interest (including post-petition interest in any
proceeding under any Bankruptcy Law) on overdue principal and premium, if any,
from time to time on demand at a rate that is 1% per annum in excess of the rate
then in effect; it will pay interest (including post-petition interest in any
proceeding under any Bankruptcy Law) on overdue installments of interest and
Liquidated Damages (without regard to any applicable grace periods) from time to
time on demand at the same rate to the extent lawful. Interest will be computed
on the basis of a 360-day year comprised of twelve 30-day months.

      2. METHOD OF PAYMENT. The Company will pay interest on the Senior Notes
(except defaulted interest) to the Persons who are registered Holders of Senior
Notes at the close of business on the August 15 or February 15 next preceding
the Interest Payment Date, even if such Senior Notes are cancelled after such
record date and on or before such Interest Payment Date, except as provided in
Section 2.13 of the Indenture with respect to defaulted interest. The Senior
Notes shall be payable as to principal, premium and interest at the office or
agency of the Company maintained for such purpose within or without the City and
State of New York, or, at the option of the Company, payment of interest may be
made by check mailed to the Holders at their addresses set forth in the register
of Holders; provided that payment by wire transfer of immediately available
funds shall be required with respect to principal of, and interest and premium
on, all Global Notes and all other Senior Notes the Holders of which shall have
provided wire transfer instructions to the Company or the Paying Agent. Such
payment shall be in such coin or currency of the United States of America as at
the time of payment is legal tender for payment of public and private debts.

      3. PAYING AGENT AND REGISTRAR. Initially, Bank of Montreal Trust Company,
the Trustee under the Indenture, shall act as Paying Agent and Registrar. The
Company may change any Paying Agent or Registrar without notice to any Holder.
The Company or any of its Subsidiaries may act in any such capacity.

      4. INDENTURE AND PLEDGE AND SECURITY AGREEMENT. The Company issued the
Senior Notes under an Indenture dated as of August 27, 1997 (the "Indenture")
between the Company and the Trustee. The terms of the Senior Notes include those
stated in the Indenture and those made a part of the Indenture by reference to
the Trust Indenture Act of 1939, as amended (15 U.S. Code " 77aaa-77bbbb) (the
"TIA"). The Senior Notes are subject to all such terms, and Holders are referred
to the Indenture and the TIA for a statement of such terms. The Senior Notes are
secured by a plege of the Pledged Collateral (as defined in the Indenture)
pursuant to the Pledge and Security Agreement referred to in the Indenture. The
Senior Notes are senior obligations of the Company limited to $250.0 million in
aggregate principal amount at maturity.

"Qualified Equity Offerings"); provided that, in either case, at least 75% in
aggregate principal amount of the Senior Notes remain outstanding immediately

redemption shall occur within 90 days of the date of the closing of such
Qualified Equity Offering.

      6.  MANDATORY REDEMPTION.

      Except as set forth in paragraph 7 below, the Company shall not be
required to make mandatory redemption or sinking fund payments with respect to

Senior Notes to repurchase all or any part (equal to $1,000 or an integral
multiple thereof) of such Holder's Senior Notes at a purchase price equal to
101% of the aggregate principal amount thereof plus accrued and unpaid interest
and Liquidated Damages, if any, to the date of repurchase (the "Change of
Control Payment"). Within ten days following any Change of Control, the Company
shall mail a notice to each Holder setting forth the procedures governing the
Change of Control Offer as required by the Indenture.

                                                      A-4

interest to the date of repurchase (or, in the case of repurchases of 13% Notes
prior to April 15, 2001, at a purchase price equal to 100% of the Accreted Value
thereof as of the date of repurchase) in accordance with the procedures set
forth in the Indenture, provided, that in the event of an Asset Sale of Stock

(in the same manner as described above) in an aggregate principal amount (or,
with respect to 13% Notes prior to April 15, 2001, an aggregate Accreted Value)
equal to the Excess Proceeds not used to purchase Senior Notes pursuant to
clause (i) of this proviso. The Senior Notes are in registered form without
coupons in denominations of $1,000 and integral multiples of $1,000. The
transfer of the Senior Notes may be registered and the Senior Notes may be
exchanged as provided in the Indenture. The Registrar and the Trustee may
require a Holder, among other things, to furnish appropriate endorsements and
transfer documents and the Company may require a Holder to pay any taxes and
fees required by law or permitted by the Indenture. The Company need not
exchange or register the transfer of any Senior Note or portion of a Senior Note
selected for redemption, except for the unredeemed portion of any Senior Note
being redeemed in part. Also, it need not exchange or register the transfer of
any Senior Notes for a period of 15 days before a selection of Senior Notes to
be redeemed or during the period between a record date and the corresponding
Interest Payment Date.

      10. PERSONS DEEMED OWNERS. The registered Holder of a Senior Note may be
treated as its owner for all purposes.

      11. AMENDMENT, SUPPLEMENT AND WAIVER. Subject to certain exceptions, the
Indenture or the Senior Notes may be amended or supplemented with the consent of
the Holders of at least a majority in principal amount of the then outstanding
Senior Notes, and any existing default or compliance with any provision of the
Indenture, the Collateral Documents or the Senior Notes may be waived with the
consent of the Holders of a majority in aggregate principal amount of the then
outstanding Senior Notes. Without the consent of any Holder of a Senior Note,
the Indenture, the Collateral Documents or the Senior Notes may be amended or
supplemented to cure any ambiguity, defect or inconsistency, to provide for
uncertificated Senior Notes in addition to or in place of certificated Senior
Notes, to provide for the assumption of the Company's obligations to Holders of
the Senior Notes in case of a merger or consolidation, to make any change that
would provide any additional rights or benefits to the Holders of the Senior
Notes or that does not adversely affect the legal rights under the Indenture of
any such Holder, or to comply with the requirements of the SEC in order to
effect or maintain the qualification of the Indenture under the Trust Indenture
Act.

      12. DEFAULTS AND REMEDIES. Events of Default include: (i) default for 30
days in the payment when due of interest on, or Liquidated Damages with respect
to, the Senior Notes; (ii) default in payment when due of principal of or
premium, if any, on the Senior Notes when the same becomes due and payable at
maturity, upon redemption (including in connection with an offer to purchase) or
otherwise, (iii) failure by the Company to comply with Section 4.07, 4.10, 4.15
or 5.01 of the Indenture; (iv) failure by the Company to comply with Section
4.09 of the Indenture; provided that in the event that the Company fails to
comply with Section 4.09 of the Indenture because indebtedness is deemed to be
incurred by a Restricted Joint Venture solely as a result of such Restricted
Joint Venture ceasing to be a Restricted Joint Venture as a result of (x) the
loss of a Local Partner or (y) the loss of management control of such Restricted
Joint Venture, and such failure continues for 90 days; (v) failure by the
Company for 30 days after notice to the Company by the Trustee or the Holders of
at least 25% in principal amount of the Senior Notes then outstanding to comply
with certain other agreements in the Indenture or the Senior Notes; (vi) default
under certain other agreements relating to Indebtedness of the Company which
default results in the acceleration of such Indebtedness prior to its express
maturity; (vii) certain final judgments for the payment of money that remain
undischarged for a period of 60 days; (viii) any breach or default by the
Company in the performance of any

                                                      A-5


<PAGE>



covenant set forth in the Collateral Agreements which breach or default
continues for 30 days, or any repudiation by the Company of its obligation under
any of the Collateral Agreements or the unenforceability of any of the
Collateral Agreements, for any reason; and (ix) certain events of bankruptcy or
insolvency with respect to the Company or any of its Significant Subsidiaries or
any of its Joint Ventures that would, if it were a Subsidiary, constitute a
Significant Subsidiary. If any Event of Default occurs and is continuing, the
Trustee or the Holders of at least 25% in principal amount of the then
outstanding Senior Notes may declare all the Senior Notes to be due and payable
immediately. Notwithstanding the foregoing, in the case of an Event of Default
arising from certain events of bankruptcy or insolvency with respect to the
Company, any of its Significant Subsidiaries or any Joint Venture that would, if
it were a Subsidiary constitute a Significant Subsidiary, or any group of
Subsidiaries or Joint Ventures that, taken together, would, constitute a
Significant Subsidiary, all outstanding Senior Notes shall become due and
payable without further action or notice. Holders of the Senior Notes may not
enforce the Indenture or the Senior Notes except as provided in the Indenture.
Subject to certain limitations, Holders of a majority in principal amount of the
then outstanding Senior Notes may direct the Trustee in its exercise of any
trust or power. The Trustee may withhold from Holders of the Senior Notes notice
of any continuing Default or Event of Default (except a Default or Event of
Default relating to the payment of principal or interest) if it determines that
withholding notice is in their interest. The Holders of a majority in aggregate
principal amount of the Senior Notes then outstanding by notice to the Trustee
may on behalf of the Holders of all of the Senior Notes waive any existing
Default or Event of Default and its consequences under the Indenture, except a
continuing Default or Event of Default in the payment of interest on, or the
principal of, the Senior Notes. The Company is required to deliver to the
Trustee annually a statement regarding compliance with the Indenture, and the
Company is required upon becoming aware of any Default or Event of Default, to
deliver to the Trustee a statement specifying such Default or Event of Default.

      13. TRUSTEE DEALINGS WITH COMPANY. The Trustee, in its individual or any
other capacity, may make loans to, accept deposits from, and perform services
for the Company or its Affiliates, and may otherwise deal with the Company or
its Affiliates, as if it were not the Trustee.

      14. NO RECOURSE AGAINST OTHERS. A director, officer, employee,
incorporator or stockholder, of the Company, as such, shall not have any
liability for any obligations of the Company under the Senior Notes or the
Indenture or for any claim based on, in respect of, or by reason of, such
obligations or their creation. Each Holder by accepting a Senior Note waives and
releases all such liability. The waiver and release are part of the
consideration for the issuance of the Senior Notes.

      15. AUTHENTICATION. This Senior Note shall not be valid until
authenticated by the manual signature of the Trustee or an authenticating agent.

      16. ABBREVIATIONS. Customary abbreviations may be used in the name of a
Holder or an assignee, such as: TEN COM (= tenants in common), TEN ENT (=
tenants by the entireties), JT TEN (= joint tenants with right of survivorship
and not as tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts
to Minors Act).

      17. ADDITIONAL RIGHTS OF HOLDERS OF TRANSFER RESTRICTED SECURITIES. In
addition to the rights provided to Holders of the Senior Notes under the
Indenture, Holders of Transferred Restricted Securities shall have all the
rights set forth in the Registration Rights Agreement dated as of August 27_,
1997, between the Company and the parties named on the signature pages thereof
(the "Registration Rights Agreement").

      18.  CUSIP NUMBERS.  Pursuant to a recommendation promulgated by the
Committee on Uniform Security Identification Procedures, the Company has caused
CUSIP numbers to be printed on the Senior

                                                      A-6

convenience to the Holders. No representation is made as to the accuracy of such

placed thereon.

charge a copy of the Indenture and/or the Registration Rights Agreement.

Capitalized terms used herein shall have the meanings assigned to them in the
Indenture referred to below.

  1. INTEREST. Hyperion Telecommunications, Inc., a Delaware corporation (the
"Company"), promises to pay interest on the principal amount of this Senior Note
at the rate of 12-1/4% per annum from August 27, 1997 until maturity (including
any additi nal interest required to be paid pursuant to the provisions of the
Registration Rights Agreement) and will be payable semi-annually in cash on
September 1 and March 1 of each year, or if any such day is not a Business Day,
on the next succeeding Business Day (each an "Interest Payment Date"); provided
that in the event that the Company does not comply with Section 1A(a) and (b) of
the Pledge Agreement, the interest rate on the Senior Notes will automatically
increase by 0.25% per annum (the "Additional Interest") to 12-1/2% and the
Additional Interest shall continue until such time as the Company complies with
its obligations under Section 1A of the Pledge Agreement, at which time the
Additional Interest shall cease. Interest and Additional Interest, if any, on
the Senior Notes will accrue from the most recent date to which interest has
been paid or, if no interest has been paid, from the date of issuance; provided
that if there is no existing Default in the payment of interest, and if this
Senior Note is authenticated between a record date referred to on the face
hereof and the next succeeding Interest Payment Date, interest shall accrue from
such next succeeding Interest Payment Date, provided, further, that the first
Interest Payment Date shall be March 1, 1998. The Company will pay interest
(including post-petition interest in any proceeding under any Bankruptcy Law) on
overdue principal and premium, if any, from time to time on demand at a rate
that is 1% per annum in excess of the rate then in effect; it will pay interest
(including post-petition interest in any proceeding under any Bankruptcy Law) on
overdue installments of interest and Liquidated Damages (without regard to any
applicable grace periods) from time to time on demand at the same rate to the
extent lawful. Interest will be computed on the basis of a 360-day year
comprised of twelve 30-day months.

  2. METHOD OF PAYMENT. The Company will pay interest on the Senior Notes
(except defaulted interest) to the Persons who are registered Holders of Senior
Notes at the close of business on the August 15 or February 15 next preceding
the Interest Payment Date, even if such Senior Notes are cancelled after such
record date and on or before such Interest Payment Date, except as provided in
Section 2.13 of the Indenture with respect to defaulted interest. The Senior
Notes shall be payable as to principal, premium and interest at the office or
agency of the Company maintained for such purpose within or without the City and
State of New York, or, at the option of the Company, payment of interest may be
made by check mailed to the Holders at their addresses set forth in the register
of Holders; provided that payment by wire transfer of immediately available
funds shall be required with respect to principal of, and interest and premium
on, all Global Notes and all other Senior Notes the Holders of which shall have
provided wire transfer instructions to the Company or the Paying Agent. Such
payment shall be in such coin or currency of the United States of America as at
the time of payment is legal tender for payment of public and private debts.

Notes under an Indenture dated as of August 27, 1997 (the "Indenture") between

in the Indenture and those made a part of the Indenture by reference to the
Trust Indenture Act of 1939, as amended (15 U.S. Code " 77aaa-77bbbb) (the

Security Agreement referred to in the Indenture.

amount of the Senior Notes then outstanding at a redemption price of 112.25% of
the principal amount thereof, with the net proceeds from either (i) an Initial
Public Offering of the common stock of the Company or (ii) a sale of the Capital
Stock (other than Disqualified Stock) of the Company to a Strategic Investor in

required to make an offer (a "Change of Control Offer") to each Holder of the
Senior Notes to repurchase all or any part (equal to $1,000 or an integral
multiple thereof) of such Holder's Senior Notes at a purchase price equal to
101% of the aggregate principal amount thereof plus accrued and unpaid interest
and Liquidated Damages, if any, to the date of repurchase (the "Change of
Control Payment"). Within ten days following any Change of Control, the Company
shall mail a notice to each Holder setting forth the procedures governing the
Change of Control Offer as required by the Indenture.

in cash equal to 100% of aggregate principal amount thereof, plus accrued and
unpaid interest to the date of repurchase (or, in the case of repurchases of 13%
Notes prior to April 15, 2001, at a purchase price equal to 100% of the Accreted
Value thereof as of the date of repurchase) in accordance with the procedures
set forth in the Indenture, provided, that in the event of an Asset Sale of
Stock Collateral, the Company shall, purchase (i) first, all Senior Notes

exchanged as provided in the Indenture. The Registrar and the Trustee may
require a Holder, among other things, to furnish appropriate endorsements and
transfer documents and the Company may require a Holder to pay any taxes and
fees required by law or permitted by the Indenture. The Company need not

      10. PERSONS DEEMED OWNERS. The registered Holder of a Senior Note may be
treated as its owner for all purposes.

      11. AMENDMENT, SUPPLEMENT AND WAIVER. Subject to certain exceptions, the
Indenture or the Senior Notes may be amended or supplemented with the consent of
the Holders of at least a majority in principal amount of the then outstanding
Senior Notes, and any existing default or compliance with any provision of the
Indenture, the Collateral Documents or the Senior Notes may be waived with the
consent of the Holders of a majority in aggregate principal amount of the then
outstanding Senior Notes. Without the consent of any Holder of a Senior Note,
the Indenture, the Collateral Documents or the Senior Notes may be amended or
supplemented to cure any ambiguity, defect or inconsistency, to provide for
uncertificated Senior Notes in addition to or in place of certificated Senior
Notes, to provide for the assumption of the Company's obligations to Holders of
the Senior Notes in case of a merger or consolidation, to make any change that
would provide any additional rights or benefits to the Holders of the Senior
Notes or that does not adversely affect the legal rights under the Indenture of
any such Holder, or to comply with the requirements of the SEC

                                                      A-4

in order to effect or maintain the qualification of the Indenture under the 
Trust Indenture Act.

      12. DEFAULTS AND REMEDIES. Events of Default include: (i) default for 30
days in the payment when due of interest on, or Liquidated Damages with respect
to, the Senior Notes; (ii) default in payment when due of principal of or
premium, if any, on the Senior Notes when the same becomes due and payable at
maturity, upon redemption (including in connection with an offer to purchase) or
otherwise, (iii) failure by the Company to comply with Section 4.07, 4.10, 4.15
or 5.01 of the Indenture; (iv) failure by the Company to comply with Section
4.09 of the Indenture; provided that in the event that the Company fails to
comply with Section 4.09 of the Indenture because indebtedness is deemed to be
incurred by a Restricted Joint Venture solely as a result of such Restricted
Joint Venture ceasing to be a Restricted Joint Venture as a result of (x) the
loss of a Local Partner or (y) the loss of management control of such Restricted
Joint Venture, and such failure continues for 90 days; (v) failure by the
Company for 30 days after notice to the Company by the Trustee or the Holders of
at least 25% in principal amount of the Senior Notes then outstanding to comply
with certain other agreements in the Indenture or the Senior Notes; (vi) default
under certain other agreements relating to Indebtedness of the Company which
default results in the acceleration of such Indebtedness prior to its express
maturity; (vii) certain final judgments for the payment of money that remain
undischarged for a period of 60 days; (viii) any breach or default by the
Company in the performance of any covenant set forth in the Collateral
Agreements which breach or default continues for 30 days, or any repudiation by
the Company of its obligation under any of the Collateral Agreements or the
unenforceability of any of the Collateral Agreements, for any reason; and (ix)
certain events of bankruptcy or insolvency with respect to the Company or any of
its Significant Subsidiaries or any of its Joint Ventures that would, if it were
a Subsidiary, constitute a Significant Subsidiary. If any Event of Default
occurs and is continuing, the Trustee or the Holders of at least 25% in
principal amount of the then outstanding Senior Notes may declare all the Senior
Notes to be due and payable immediately. Notwithstanding the foregoing, in the
case of an Event of Default arising from certain events of bankruptcy or
insolvency with respect to the Company, any of its Significant Subsidiaries or
any Joint Venture that would, if it were a Subsidiary constitute a Significant
Subsidiary, or any group of Subsidiaries or Joint Ventures that, taken together,
would, constitute a Significant Subsidiary, all outstanding Senior Notes shall
become due and payable without further action or notice. Holders of the Senior
Notes may not enforce the Indenture or the Senior Notes except as provided in
the Indenture. Subject to certain limitations, Holders of a majority in
principal amount of the then outstanding Senior Notes may direct the Trustee in
its exercise of any trust or power. The Trustee may withhold from Holders of the
Senior Notes notice of any continuing Default or Event of Default (except a
Default or Event of Default relating to the payment of principal or interest) if
it determines that withholding notice is in their interest. The Holders of a
majority in aggregate principal amount of the Senior Notes then outstanding by
notice to the Trustee may on behalf of the Holders of all of the Senior Notes
waive any existing Default or Event of Default and its consequences under the
Indenture, except a continuing Default or Event of Default in the payment of
interest on, or the principal of, the Senior Notes. The Company is required to
deliver to the Trustee annually a statement regarding compliance with the
Indenture, and the Company is required upon becoming aware of any Default or
Event of Default, to deliver to the Trustee a statement specifying such Default
or Event of Default.

      13. TRUSTEE DEALINGS WITH COMPANY. The Trustee, in its individual or any
other capacity, may make loans to, accept deposits from, and perform services
for the Company or its Affiliates, and may otherwise deal with the Company or
its Affiliates, as if it were not the Trustee.

      14. NO RECOURSE AGAINST OTHERS. A director, officer, employee,
incorporator or stockholder, of the Company, as such, shall not have any
liability for any obligations of the Company under the Senior Notes or the
Indenture or for any claim based on, in respect of, or by reason of, such
obligations or their creation. Each Holder by accepting a Senior Note waives and
releases all such liability. The waiver and release are

                                                      A-5


<PAGE>



part of the consideration for the issuance of the Senior Notes.

      15. AUTHENTICATION. This Senior Note shall not be valid until
authenticated by the manual signature of the Trustee or an authenticating agent.

      16. ABBREVIATIONS. Customary abbreviations may be used in the name of a
Holder or an assignee, such as: TEN COM (= tenants in common), TEN ENT (=
tenants by the entireties), JT TEN (= joint tenants with right of survivorship
and not as tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts
to Minors Act).

      17. ADDITIONAL RIGHTS OF HOLDERS OF TRANSFER RESTRICTED SECURITIES. In
addition to the rights provided to Holders of the Senior Notes under the
Indenture, Holders of Transferred Restricted Securities shall have all the
rights set forth in the Registration Rights Agreement dated as of August 27,
1997, between the Company and the parties named on the signature pages thereof
(the "Registration Rights Agreement").

      18. CUSIP NUMBERS. Pursuant to a recommendation promulgated by the
Committee on Uniform Security Identification Procedures, the Company has caused
CUSIP numbers to be printed on the Senior Notes and the Trustee may use CUSIP
numbers in notices of redemption as a convenience to the Holders. No
representation is made as to the accuracy of such numbers either as printed on
the Senior Notes or as contained in any notice of redemption and reliance may be
placed only on the other identification numbers placed thereon.

      The Company shall furnish to any Holder upon written request and without
charge a copy of the Indenture and/or the Registration Rights Agreement.

      agreement, judgment, injunction, order, decree or other instrument binding
      upon the Company, or result in the creation or imposition of any Lien on
      any assets of the Company, other than the Lien contemplated hereby.

           (b) The Pledged Shares have been duly authorized and validly issued
      and are fully paid and non-assessable.

           (c) The Pledged Shares constitute all of the issued and outstanding
      Equity Interests of the Pledged Entities and constitute all of the Equity
      Interests of the Pledged Entities beneficially owned by the Company.

           (d) The Company is the legal, record and beneficial owner of the
      Pledged Collateral, free and clear of any and all Liens or claims of any
      Person except (i) with respect to the Initial Collateral, the security
      interest created by this Agreement and (ii) with respect to the Additional
      Collateral, the Lien contained in the applicable partnership agreement;
      provided that upon the pledge by the Company of



<PAGE>




      the Additional Collateral pursuant to the terms of this Agreement, such
      collateral will be free and clear of any and all Liens or claims of any
      person except for the security interest created by this Agreement.

           (e) The Company has full power and authority to enter into this
      Agreement and has the right to vote, pledge and grant a security interest
      in the Initial Collateral as provided by this Agreement, and with respect
      to the Additional Collateral, upon the consummation of the Rollups, the
      Company will have the right to vote, pledge and grant a security interest
      in the Additional Collateral as provided by this Agreement.

           (f) This Agreement has been duly executed and delivered by the
      Company and constitutes a legal, valid and binding obligation of the
      Company, enforceable against the Company in accordance with its terms.

           (g) Upon the delivery to the Collateral Agent of the Pledged
      Collateral and (as to certain proceeds therefrom, if any) the filing of
      Uniform Commercial Code (the AUCC@) financing statements in the
      appropriate jurisdictions, the pledge of the Pledged Collateral pursuant
      to this Agreement creates a valid and perfected first priority security
      interest in the Pledged Collateral, securing the payment of the
      Obligations for the benefit of the Collateral Agent and the Holders of
      Notes, and enforceable as such against all creditors of the Company and
      any Persons purporting to purchase any of the Pledged Collateral from the
      Company.

           (h) No consent of any other Person and no consent, authorization,
      approval, or other action by, and no notice to or filing with, any
      governmental authority or regulatory body is required either (i) for the
      pledge by the Company of the Pledged Collateral pursuant to this Agreement
      or for the execution, delivery or performance of this Agreement by the
      Company or (ii) except as set forth on Schedule II hereto with respect to
      the Pledged Collateral, for the exercise by the Collateral Agent of the
      voting or other rights provided for in this Agreement or the remedies in
      respect of the Pledged Collateral pursuant to this Agreement (except, in
      each case, as may be required in connection with such disposition by laws
      affecting the offering and sale of securities).

           (i) Other than proceedings related to obtaining governmental approval
      for the Rollups, no litigation, investigation or proceeding of or before
      any arbitrator or governmental authority is pending or, to the best
      knowledge of the Company, threatened by or against the Company or against
      any of its properties or revenues with respect to this Agreement or any of
      the transactions contemplated hereby.

           (j) The pledge of the Pledged Collateral pursuant to this Agreement
      is not prohibited by any applicable law or governmental regulation,
      release, interpretation or opinion of the Board of Governors of the
      Federal Reserve System or other regulatory agency (including, without
      limitation, Regulations G, T, U and X of the Board of Governors of the
      Federal Reserve System).

           (k) All information set forth herein relating to the Pledged
      Collateral is accurate and complete in all respects.


           SECTION 5. Further Assurance.  The Company shall at all times cause
the security  interests  granted  pursuant to this Agreement to constitute valid
perfected first priority security interests in the Pledged



<PAGE>




Collateral, enforceable as such against all creditors of the Company and (except
as otherwise specifically provided herein) any Persons purporting to purchase
any Pledged Collateral from the Company. The Company shall, promptly upon
request by the Collateral Agent, execute and deliver or cause to be executed and
delivered, or use its best efforts to procure, all stock powers, proxies, tax
stamps, assignments, instruments and other documents, all in form and substance
satisfactory to the Collateral Agent, deliver any instruments to the Collateral
Agent and take any other actions that are necessary or, in the reasonable
opinion of the Collateral Agent, desirable to perfect, continue the perfection
of, or protect the first priority of the Collateral Agent's security interest
in, the Pledged Collateral, to protect the Pledged Collateral against the
rights, claims, or interests of third persons, to enable the Collateral Agent to
exercise or enforce its rights and remedies hereunder, or otherwise to effect
the purposes of this Agreement. The Company also hereby authorizes the
Collateral Agent to file any financing or continuation statements with respect
to the Pledged Collateral without the signature of the Company to the extent
permitted by applicable law. The Company shall pay all costs incurred in
connection with any of the foregoing.

           SECTION 6. Voting Rights; Dividends; Etc.

           (a) So long as no Event of Default shall have occurred and be
      continuing, the Company shall be entitled to exercise any and all voting
      and other consensual rights pertaining to the Pledged Shares or any part
      thereof for any purpose not inconsistent with the terms of this Agreement
      or the Indenture; provided, however, that the Company shall not exercise
      or shall refrain from exercising any such right if such action or omission
      would be inconsistent with or violate any provisions of this Agreement or
      the Indenture.

           (b) So long as no Event of Default shall have occurred and be
      continuing, and subject to the other terms and conditions of the
      Indenture, the Company shall be entitled to receive, and to utilize
      (subject to the provisions of the Indenture) free and clear of the Lien of
      this Agreement, all regular cash dividends, interest, principal and other
      payments and distributions paid from time to time in respect of the
      Pledged Shares, provided that upon the occurrence and during the
      continuance of an Event of Default, any and all (i) dividends, other
      distributions, interest and principal payments paid or payable in the form
      of instruments and/or other property received, receivable or otherwise
      distributed in respect of, or in exchange for, any Pledged Collateral,
      (ii) dividends and other distributions paid or payable in cash in respect
      of any Pledged Shares in connection with a partial or total liquidation or
      dissolution or in connection with a reduction of capital, capital surplus
      or paid-in-surplus, and (iii) cash paid, payable or otherwise distributed
      in redemption of, or in exchange for, any Pledged Collateral, shall in
      each case be forthwith delivered to the Collateral Agent to hold as
      Pledged Collateral and shall, if received by the Company, be received in
      trust for the benefit of the Collateral Agent and the Holders of Notes, be
      segregated from the other property and funds of the Company and be
      forthwith delivered to the Collateral Agent as Pledged Collateral in the
      same form as so received (with any necessary endorsements).

           (c) The Collateral Agent shall execute and deliver (or cause to be
      executed and delivered) to the Company all such proxies and other
      instruments as the Company may reasonably request in writing for the
      purpose of enabling the Company to exercise the voting and other rights
      that it is entitled to exercise pursuant to Sections 6(a) and 6(b) above.

           (d)  Upon the occurrence and during the continuance of an Event of
      Default, (i) all rights of the



<PAGE>




      Company to exercise the voting and other consensual rights that it would
      otherwise be entitled to exercise pursuant to Section 6(a) shall
      immediately and automatically cease, and all such rights shall thereupon
      become vested in the Collateral Agent, which, to the extent permitted by
      law, shall thereupon have the sole right to exercise such voting and other
      consensual rights, and (ii) all dividends and other distributions payable
      in respect of the Pledged Collateral shall be paid to the Collateral Agent
      and the Company's right to receive such cash payments pursuant to Section
      6(b) hereof shall immediately cease.

           (e) Upon the occurrence and during the continuance of an Event of
      Default, the Company shall execute and deliver (or cause to be executed
      and delivered) to the Collateral Agent all such proxies, dividend and
      interest payment orders and other instruments as are necessary or
      desirable to enable the Collateral Agent to exercise the voting and other
      rights that it is entitled to exercise pursuant to Section 6(d) above.

           (f) All payments of interest, principal or premium and all dividends
      and other distributions that are received by the Company contrary to the
      provisions of this Section 6 shall be received in trust for the benefit of
      the Collateral Agent and the Holders, shall be segregated from the other
      property or funds of the Company and shall be forthwith delivered to the
      Collateral Agent as Pledged Collateral in the same form as so received
      (with any necessary endorsements).

           SECTION 7. Covenants. The Company hereby covenants and agrees with
the Collateral Agent and the Holders of Notes that it shall comply with all of
the obligations, requirements and restrictions applicable to the Company
contained in the Indenture. The Company further covenants and agrees, from and
after the date of this Agreement and until the Obligations have been paid in
full, as follows:

           (a) The Company agrees that it shall not (i) other than as permitted
by and in accordance with the Indenture and Section 18.17(b) hereof, sell,
assign, transfer, convey or otherwise dispose of, or grant any option or warrant
with respect to, any of the Pledged Collateral without the prior written consent
of the Collateral Agent acting in accordance with the directions of the Holders,
(ii) create or permit to exist any Lien upon or with respect to any of the
Pledged Collateral (except for the security interest granted under this
Agreement, and, with respect to the Additional Collateral, until such time as
the Additional Collateral is pledged for the benefit of the Holders of the Notes
pursuant to Section 1A hereof, the Liens contained in the applicable partnership
agreements) and at all times will be the sole beneficial owner of the Pledged
Collateral, (iii) enter into any agreement or understanding that purports to or
that may restrict or inhibit the Collateral Agent's rights or remedies
hereunder, including, without limitation, the Collateral Agent's right to sell
or otherwise dispose of the Pledged Collateral, (iv) take any action, or permit
the taking of any action by the Pledged Entities, with respect to the Pledged
Collateral the taking of which would result in a violation of the Indenture or
this Agreement, including, without limitation, the issuance by the Pledged
Entities of any additional Equity Interests or promissory notes or the
incurrence by the Pledged Entities of any Indebtedness to Persons other than the
Company (except as permitted by the Indenture), (v) permit any of the Pledged
Entities to merge or consolidate with or into another person or entity or sell
or transfer all or substantially all of its assets to another person or entity,
unless (x) the Company shall have delivered to the Collateral Agent an Opinion
of Counsel substantially in the form of Exhibit A-1 hereto and a certificate
executed by the President and Chief Financial Officer of the Company
substantially in the form of Exhibit B hereto and (y) all outstanding capital
stock of the surviving entity in such merger or consolidation or of the entity
to whom such sale or transfer was made, together with any promissory notes
issued by such entity in favor of the Company are, upon such merger or
consolidation, pledged hereunder to and deposited with the Collateral



<PAGE>




Agent, or (vi) fail to pay or discharge any tax, assessment or levy of any
nature not later than five days prior to the date of any proposed sale under any
judgement, writ or warrant of attachment with regard to the Pledged Collateral.

           (b) The Company agrees that immediately upon becoming the beneficial
owner of any additional shares of Capital Stock or Equity Interests of the
Pledged Entities (including as a result of the merger or consolidation of the
Issuer with or into another entity) it shall pledge and deliver to the
Collateral Agent for its benefit and the ratable benefit of the Holders and
grant to the Collateral Agent for its benefit and the ratable benefit of the
Holders, a continuing first priority security interest in such shares or Equity
Interests (as well as instruments of transfer or assignment duly executed in
blank and undated and any necessary stock transfer tax stamps, all in form and
substance satisfactory to create a first priority security interest in the
Pledged Collateral). The Company further agrees that it shall promptly deliver
to the Collateral Agent a certificate executed by a principal executive officer
of the Company describing such additional shares or Equity Interests and
certifying that the same have been duly pledged and delivered to the Collateral
Agent hereunder.

           (b) The Company agrees that, in accordance with the terms of Section
1A hereof, it shall pledge and deliver to the Collateral Agent for its benefit
and the ratable benefit of the Holders and grant to the Collateral Agent for its
benefit and the ratable benefit of the Holders, a continuing first priority
security interest in the Additional Pledged Shares (as well as instruments of
transfer or assignment duly executed in blank and undated and any necessary
stock transfer tax stamps, all in form and substance satisfactory to create a
first priority security interest in the Additional Pledged Collateral). The
Company further agrees that it shall concurrently with such pledge of the
Additional Pledged Collateral, deliver to the Collateral Agent an opinion of
counsel substantially in the form of Exhibit A-2 hereto and certificate executed
by a principal executive officer of the Company certifying that the Additional
Pledged Shares have been duly pledged and delivered to the Collateral Agent
hereunder and constitutes Pledged Collateral for all purposes hereunder and
under the Indenture.

           SECTION 8. Power of Attorney. In addition to all of the powers
granted to the Collateral Agent pursuant to Section 10.06 of the Indenture, the
Company hereby appoints and constitutes the Collateral Agent as the Company's
attorney-in-fact to exercise all of the following powers upon and at any time
after the occurrence of an Event of Default for so long as such Event of Default
is continuing: (i) collection of proceeds of any Pledged Collateral; (ii)
conveyance of any item of Pledged Collateral to any purchaser thereof; (iii)
giving of any notices or recording of any Liens under Section 5 hereof; (iv)
making of any payments (upon receipt of funds thereof) or taking any acts under
Section 9 hereof and (v) paying or discharging taxes or Liens levied or placed
upon or threatened against the Pledged Collateral, in the amounts necessary to
discharge the same, and such payments made by the Collateral Agent to become the
obligations of the Company to the Collateral Agent, due and payable immediately
without demand. The Collateral Agent's authority hereunder shall include,
without limitation, the authority to endorse and negotiate, for the Collateral
Agent's own account, any checks or instruments in the name of the Company,
execute and give receipt for any certificate of ownership or any document,
transfer title to any item of Pledged Collateral, sign the Company's name on all
financing statements or any other documents deemed necessary or appropriate to
preserve, protect or perfect the security interest in the Pledged Collateral and
to file the same, prepare, file and sign the Company's name on any notice of
Lien, and prepare, file and sign the Company's name on a proof of claim in
bankruptcy or similar document against any customer of the Company, and to take
any other actions arising from or incident to the powers granted to the
Collateral Agent in this Agreement. This



<PAGE>




power of attorney is coupled with an interest and is irrevocable by the Company.

           SECTION 9. Collateral Agent May Perform. If the Company fails to
perform any agreement contained herein, the Collateral Agent may itself perform,
or cause performance of, such agreement, and the reasonable expenses of the
Collateral Agent incurred in connection therewith shall be payable by the
Company under Section 14 hereof. No provision of this Agreement shall require
the Collateral Agent to expend or risk its own funds or incur any liability. The
Collateral Agent shall be under no obligation to exercise any of its rights and
powers under this Agreement at the request of the Holders of the Notes, unless
such Holders shall have offered the Collateral Agent security and indemnity
satisfactory to it against any loss, liability or expenses.

           SECTION 10. No Assumption of Duties; Reasonable Care. The rights and
powers granted to the Collateral Agent hereunder are being granted in order to
preserve and protect the Collateral Agent's and the Holders' of Notes security
interest in and to the Pledged Collateral granted hereby and shall not be
interpreted to, and shall not, impose any duties on the Collateral Agent in
connection therewith. The Collateral Agent shall be deemed to have exercised
reasonable care in the custody and preservation of the Pledged Collateral in its
possession if the Pledged Collateral is accorded treatment substantially equal
to that which the Collateral Agent accords its own property, it being understood
that the Collateral Agent shall not have any responsibility for (i) ascertaining
or taking action with respect to calls, conversions, exchanges, maturities,
tenders or other matters relative to any Pledged Collateral, whether or not the
Collateral Agent has or is deemed to have knowledge of such matters, or (ii)
taking any necessary steps to preserve rights against any parties with respect
to any Pledged Collateral.

           SECTION 11. Subsequent Changes Affecting Collateral. The Company
represents to the Collateral Agent and the Holders of Notes that the Company has
made its own arrangements for keeping informed of changes or potential changes
affecting the Pledged Collateral (including, but not limited to, rights to
convert, rights to subscribe, payment of dividends, payments of interest and/or
principal, reorganization or other exchanges, tender offers and voting rights),
and the Company agrees that the Collateral Agent and the Holders of Notes shall
have no responsibility or liability for informing the Company of any such
changes or potential changes or for taking any action or omitting to take any
action with respect thereto. The Company covenants that it shall not, without
the prior written consent of the Collateral Agent, vote to enable, or take any
other action to permit, any Pledged Entity to issue any capital stock or other
securities or to sell or otherwise dispose of, or grant any option with respect
to, any of the Pledged Collateral or create or permit to exist any Lien upon or
with respect to any of the Pledged Collateral, except for the security interests
granted under this Agreement. The Company shall defend the right, title and
interest of the Collateral Agent and the Holders of Notes in and to the Pledged
Collateral against the claims and demands of all Persons.

           SECTION 12. Remedies Upon Default.

                (a) If any Event of Default shall have occurred and be
      continuing, the Collateral Agent and the Holders of Notes shall have, in
      addition to all other rights given by law or by this Agreement or the
      Indenture, all of the rights and remedies with respect to the Pledged
      Collateral of a secured party under the UCC as in effect in the State of
      New York at that time. The Collateral Agent may, without notice and at its
      option, transfer or register, and the Company shall register or cause to
      be registered upon request therefor by the Collateral Agent, the Pledged
      Collateral or any part thereof on the books of each



<PAGE>




      Pledged Entity into the name of the Collateral Agent or the Collateral
      Agent's nominee(s), with or without any indication that such Pledged
      Collateral is subject to the security interest hereunder. In addition,
      with respect to any Pledged Collateral that shall then be in or shall
      thereafter come into the possession or custody of the Collateral Agent,
      the Collateral Agent may sell or cause the same to be sold at any broker's
      board or at public or private sale, in one or more sales or lots, at such
      price or prices as the Collateral Agent may deem best, for cash or on
      credit or for future delivery, without assumption of any credit risk. The
      purchaser of any or all Pledged Collateral so sold shall thereafter hold
      the same absolutely, free from any claim, encumbrance or right of any kind
      whatsoever. Unless any of the Pledged Collateral threatens to decline
      speedily in value or is or becomes of a type sold on a recognized market,
      the Collateral Agent shall give the Company reasonable notice of the time
      and place of any public sale thereof, or of the time after which any
      private sale or other intended disposition is to be made. Any sale of the
      Pledged Collateral conducted in conformity with reasonable commercial
      practices of banks, insurance companies, commercial finance companies, or
      other financial institutions disposing of property similar to the Pledged
      Collateral shall be deemed to be commercially reasonable. Any requirements
      of reasonable notice shall be met if such notice is mailed to the Company
      as provided below in Section 18.1 at least ten days before the time of the
      sale or disposition. Any other requirement of notice, demand or
      advertisement for sale is, to the extent permitted by law, waived. The
      Collateral Agent or any Holder of Notes may, in its own name or in the
      name of a designee or nominee, buy any of the Pledged Collateral at any
      public sale and, if permitted by applicable law, at any private sale. All
      expenses (including court costs and reasonable attorneys' fees and
      disbursements) of, or incident to, the enforcement of any of the
      provisions hereof shall be recoverable from the proceeds of the sale or
      other disposition of the Pledged Collateral.

                (b) If the Collateral Agent shall determine to exercise its
      right to sell any or all of the Pledged Shares pursuant to Section 12(a)
      above, and if in the opinion of counsel for the Collateral Agent it is
      necessary, or if in the opinion of the Collateral Agent it is advisable,
      to have the Pledged Shares or that portion thereof to be sold, registered
      under the provisions of the Securities Act of 1933, as amended (the
      ASecurities Act@), the Company shall cause each Pledged Entity to (i)
      execute and deliver, and cause its directors and officers to execute and
      deliver, all at the expense of the Company, all such instruments and
      documents, and to do or cause to be done all such other acts and things as
      may be necessary or, in the opinion of the Collateral Agent, advisable to
      register such Pledged Shares under the provisions of the Securities Act,
      (ii) cause the registration statement relating thereto to become effective
      and to remain effective for a period of 180 days from the date of the
      first public offering of such Pledged Shares, or that portion thereof to
      be sold and (iii) make all amendments thereto and/or to the related
      prospectus that, in the opinion of the Collateral Agent, are necessary or
      advisable, all in conformity with the requirements of the Securities Act
      and the rules and regulations of the Securities and Exchange Commission
      applicable thereto; provided that in the event that state regulatory law
      prohibits the registration and sale of shares of any particular Pledged
      Entity, such Pledged Entity shall not be required to register the shares
      of that particular Pledged Entity. The Company agrees to cause each
      Pledged Entity to comply with the provisions of the securities or ABlue
      Sky@ laws of any jurisdiction that the Collateral Agent shall designate
      for the sale of the Pledged Shares and to make available to each such
      Pledged Entity's security holders, as soon as practicable, an earnings
      statement (which need not be audited) that will satisfy the provisions of
      Section 11(a) of the Securities Act. The Company shall cause each such
      Pledged Entity to furnish to the Collateral Agent such number of copies as
      the Collateral Agent may reasonably request of each registration statement
      and preliminary and final prospectus, to notify the Collateral Agent
      promptly of the happening of any event as a result of which



<PAGE>




      any then effective prospectus includes an untrue statement of a material
      fact or omits to state a material fact required to be stated therein or
      necessary to make the statements therein, in the light of circumstances
      under which they were made, not misleading, and to cause the Collateral
      Agent to be furnished with such number of copies as the Collateral Agent
      may request of such supplement to or amendment of such prospectus. The
      Company shall cause each such Pledged Entity, to the extent permitted by
      law, to indemnify, defend and hold harmless the Collateral Agent and the
      Holders of Notes from and against all losses, liabilities, expenses or
      claims (including reasonable legal expenses and the reasonable costs of
      investigation) that the Collateral Agent or the Holders of Notes may incur
      under the Securities Act or otherwise, insofar as such losses,
      liabilities, expenses or claims arise out of or are based upon any alleged
      untrue statement of a material fact contained in such registration
      statement (or any amendment thereto) or in any preliminary or final
      prospectus (or any amendment or supplement thereto), or arise out of or
      are based upon any alleged omission to state a material fact required to
      be stated therein or necessary to make the statements therein not
      misleading, except to the extent that any such losses, liabilities,
      expenses or claims arise solely out of or are based upon any such alleged
      untrue statement made or such alleged omission to state a material fact
      included or excluded on the written direction of the Collateral Agent. The
      Company shall cause each such Pledged Entity to bear all costs and
      expenses of carrying out their respective obligations hereunder.

                (c) In view of the fact that federal and state securities laws
      may impose certain restrictions on the method by which a sale of the
      Pledged Collateral may be effected after an Event of Default, the Company
      agrees that upon the occurrence or existence of any Event of Default, the
      Collateral Agent may, from time to time, attempt to sell all or any part
      of the Pledged Collateral by means of a private placement, restricting the
      prospective purchasers to those who will represent and agree that they are
      purchasing for investment only and not for distribution. In so doing, the
      Collateral Agent may solicit offers to buy the Pledged Collateral, or any
      part of it, for cash, from a limited number of investors who might be
      interested in purchasing the Pledged Collateral. The Company acknowledges
      and agrees that any such private sale may result in prices and terms less
      favorable than if such sale were a public sale and, notwithstanding such
      circumstances, agrees that any such private sale shall be deemed to have
      been made in a commercially reasonable manner. The Collateral Agent shall
      be under no obligation to delay a sale of any of the Pledged Collateral
      for the period of time necessary to permit any Pledged Entity to register
      such securities for public sale under the Securities Act, or under
      applicable state securities laws, even if any such Pledged Entity agrees
      to do so.

                (d) The Company further agrees to use its best efforts to do or
      cause to be done all such other acts as may be necessary to make such sale
      or sales of all or any portion of the Pledged Collateral pursuant to this
      Section 12 valid and binding and in compliance with any and all other
      applicable requirements of law. The Company further agrees that a breach
      of any of the covenants contained in this Section 12 will cause
      irreparable injury to the Collateral Agent and the Holders of Notes, that
      the Collateral Agent and the Holders of Notes have no adequate remedy at
      law in respect of such breach and, as a consequence, that each and every
      covenant contained in this Section 12 shall be specifically enforceable
      against the Company, and the Company hereby waives and agrees not to
      assert any defenses against an action for specific performance of such
      covenants except for a defense that no Event of Default has occurred under
      the Indenture.

                (e) Notwithstanding anything contained herein which may be
      construed to the contrary, no action shall be taken by the Collateral
      Agent which may require the consent or approval of the Federal



<PAGE>

severable, and if any clause or provision shall be held invalid or unenforceable
in whole or in part in any jurisdiction, then such invalidity or
unenforceability shall affect in that jurisdiction only such clause or
provision, or part thereof, and shall not in any manner affect such clause or
provision in any other jurisdiction or any other clause or provision of this
Agreement in any jurisdiction.

                Section 18.5 No Recourse Against Others. No director, officer,
employee, stockholder or affiliate, as such, of the Company or any Pledged
Entity shall have any liability for any obligations of the Company under this
Agreement or for any claim based on, in respect of or by reason of such
obligations or their creation. Each Holder of Notes, by accepting a Note, waives
and releases all such liability. The waiver and release are part of the
consideration for the issue of the Notes.

                Section 18.6 Headings. The headings of the Articles and Sections
of this Agreement have been inserted for convenience of reference only, are not
to be considered a part hereof and shall in no way modify or restrict any of the
terms or provisions hereof.

                Section 18.7 Counterpart Originals. This Agreement may be signed
in two or more counterparts. Each signed copy shall be an original, but all of
them together represent one and the same agreement. Each counterpart may be

                Section 18.8 Benefits of Agreement. Nothing in this Agreement,
express or implied, shall give to any Person, other than the parties hereto and

the Company from any provision of this Agreement shall be effective only if made
or given in compliance with all of the terms and provisions of the Indenture
necessary for amendments or waivers of, or consents to any departure by the
Company from any provision of the Indenture, as applicable, and neither the
Collateral Agent or the Trustee nor any Holder of Notes shall be deemed, by any
act, delay, indulgence, omission or otherwise, to have waived any right or
remedy hereunder or to have acquiesced in any Event of Default or in any breach
of any of the terms and conditions hereof. Failure of the Collateral Agent or
any Holder of Notes to exercise, or delay in exercising, any right, power or

exercise of any right, power or privilege hereunder shall preclude any other or
further exercise thereof or the exercise of any other right, power or privilege.
A waiver by the Collateral Agent or any Holder of Notes of any right or remedy
hereunder on any one occasion shall not be construed as a bar to any right or
remedy that the Collateral Agent or such Holder of Notes would otherwise have on
any future occasion. The rights and remedies herein provided are cumulative, may
be exercised singly or concurrently and are not exclusive of any rights or
remedies provided by law.

                Section 18.10 Interpretation of Agreement. Time is of the
essence in each provision of this Agreement of which time is an element. All

term or provision of this Agreement conflicts with the Indenture and is not
dealt with herein with more specificity,



<PAGE>




the Indenture shall control with respect to the subject matter of such term or
provision. Acceptance of or acquiescence in a course of performance rendered
under this Agreement shall not be relevant to determine the meaning of this
Agreement even though the accepting or acquiescing party had knowledge of the
nature of the performance and opportunity for objection.

This Agreement shall create a continuing security interest in the Pledged
Collateral and shall (i) remain in full force and effect until the payment in
full of all the Obligations and all the fees and expenses owing to the
Collateral Agent, (ii) be binding upon the Company, its successors and assigns,
and (iii) inure, together with the rights and remedies of the Collateral Agent
hereunder, to the benefit of the Collateral Agent, the Holders of Notes and
their respective successors, transferees and assigns.

effective or be reinstated if at any time any amount received by the Collateral
Agent or any Holder of Notes in respect of the Obligations is rescinded or must
otherwise be restored or returned by the Collateral Agent or any Holder of Notes
upon the insolvency, bankruptcy, dissolution, liquidation or reorganization of
the Company or upon the appointment of any receiver, intervenor, conservator,
trustee or similar official for the Company or any substantial part of its
assets, or otherwise, all as though such payments had not been made.

warranties and covenants of the Company contained herein shall survive the
execution and delivery of this Agreement, and shall terminate only upon the full
and final payment and performance by the Company of the Obligations; except that

                Section 18.15 Authority of the Collateral Agent.

                (a) Subject to the provisions of Section 10.06 of the Indenture,
      the Collateral Agent shall have and be entitled to exercise all powers
      hereunder that are specifically granted to the Collateral Agent by the
      terms hereof, together with such powers as are reasonably incident
      thereto. The Collateral Agent may perform any of its duties hereunder or
      in connection with the Pledged Collateral by or through agents or
      employees and shall be entitled to retain counsel of its choice and to act
      in reliance upon the advice of such counsel concerning all such matters.
      Neither the Collateral Agent nor any director, officer, employee, attorney
      or agent of the Collateral Agent shall be responsible for the validity,
      effectiveness or sufficiency hereof or of any document or security
      furnished pursuant hereto. The Collateral Agent and its directors,
      officers, employees, attorneys and agents shall be entitled to rely on any
      communication, instrument or document believed by it or them to be genuine
      and correct and to have been signed or sent by the proper person or
      persons. The Company agrees to indemnify and hold harmless the Collateral
      Agent, the Holders of Notes and any other Person from and against any and
      all costs, expenses (including the reasonable fees and disbursements of
      counsel (including, the allocated costs of inside counsel)), claims and
      liabilities incurred by the Collateral Agent, the Holders of Notes or such
      Person hereunder, unless such claim or liability shall be due to willful
      misconduct or gross negligence on the part of the Collateral Agent, the
      Holders of Notes or such Person.

                (b) The Company acknowledges that the rights and
      responsibilities of the Collateral Agent under this Agreement with respect
      to any action taken by the Collateral Agent or the exercise or
      non-exercise by the Collateral Agent of any option, right, request,
      judgment or other right or remedy provided for herein or resulting or
      arising out of this Agreement shall, as between the Collateral Agent and
      the Holders of Notes, be governed by the Indenture and by such other
      agreements with respect thereto as may exist from time to time among them,
      but, as between the Collateral Agent and the Company, the Collateral Agent
      shall be conclusively presumed to be acting as agent for the Holders of
      Notes with full and valid authority so to act or refrain from acting, and
      the Company shall not be obligated or entitled to make any inquiry
      respecting such authority.

                (c) No provision of this Agreement shall require the Collateral
      Agent to expend or risk its own funds or incur any liability. The
      Collateral Agent shall be under no obligation to exercise any of its
      rights and powers under this Agreement at the request of any Holders,
      unless such Holder shall have offered to the Collateral Agent security and
      indemnity satisfactory to it against any loss, liability or expense.

                Section 18.16 Resignation or Removal of the Collateral Agent.
Until such time as the Obligations shall have been paid in full, the Collateral
Agent may at any time, by giving written notice to the Company and Holders of
Notes, resign and be discharged of the responsibilities hereby created, such
resignation to become effective upon (i) the appointment of a successor
Collateral Agent and (ii) the acceptance of such appointment by such successor
Collateral Agent. As promptly as practicable after the giving of any such
notice, the Holders of Notes shall appoint a successor Collateral Agent, which
successor Collateral Agent shall be reasonably acceptable to the Company. If no
successor Collateral Agent shall be appointed and shall have accepted such
appointment within 60 days after the Collateral Agent gives the aforesaid notice
of resignation, the Collateral Agent may apply to any court of competent
jurisdiction to appoint a successor Collateral Agent to act until such time, if
any, as a successor shall have been appointed as provided in this Section 18.16.
Any successor so appointed by such court shall immediately and without



<PAGE>




further act be superseded by any successor Collateral Agent appointed by the
Holders of a majority of the then outstanding Notes, as provided in this Section
18.16. Simultaneously with its replacement as Collateral Agent hereunder, the
Collateral Agent so replaced shall deliver to its successor all documents,
instruments, certificates and other items of whatever kind (including, without
limitation, the certificates and instruments evidencing the Pledged Collateral
and all instruments of transfer or assignment) held by it pursuant to the terms
hereof. The Collateral Agent that has resigned shall be entitled to fees, costs
and expenses to the extent incurred or arising, or relating to events occurring,
before its resignation or removal.

                Section 18.17 Release; Termination of Agreement.

                (a) Subject to the provisions of Section 18.12 hereof, this
      Agreement shall terminate (i) upon full and final payment and performance
      of the Obligations (and upon receipt by the Collateral Agent of the
      Company's written certification that all such Obligations have been
      satisfied) and payment in full of all fees and expenses owing by the
      Company to the Collateral Agent or (ii) on the day after the first
      anniversary of the Legal Defeasance of all of the Obligations pursuant to
      Section 8.02 of the Indenture (other than those surviving Obligations
      specified therein). At such time, the Collateral Agent shall, at the
      request of the Company, reassign and redeliver to the Company all of the
      Pledged Collateral hereunder that has not been sold, disposed of, retained
      or applied by the Collateral Agent in accordance with the terms hereof.
      Such reassignment and redelivery shall be without warranty by or recourse
      to the Collateral Agent, except as to the absence of any prior assignments
      by the Collateral Agent of its interest in the Pledged Collateral, and
      shall be at the expense of the Company.

                (b) The Company agrees that it shall not, except as permitted by
      the Indenture, sell or dispose of, or grant any option or warrant with
      respect to, any of the Pledged Collateral; provided, however, that if the
      Company shall sell any of the Pledged Collateral in accordance with the
      terms of the Indenture, including the requirement that the Company apply
      the Net Proceeds of such sale in accordance with Section 4.10 of the
      Indenture, the Collateral Agent shall, at the request of the Company and
      subject to requirements of Section 10.03, 10.04 and 10.05 of the
      Indenture, release the Pledged Collateral subject to such sale free and
      clear of the Lien and security interest under this Agreement.

                Section 18.18 Final Expression. This Agreement, together with
any other agreement executed in connection herewith, is intended by the parties
as a final expression of their Agreement and is intended as a complete and
exclusive statement of the terms and conditions thereof.

                                           FORM OF SOLVENCY CERTIFICATE



The undersigned, _______________ and ________________, respectively the
President and Chief Financial Officer of Hyperion Telecommunications, Inc., a
Delaware corporation ("the Company"), certify that they are authorized to
execute this Certificate in the name and on behalf of the Company, and further
certify as follows (capitalized terms used but not defined herein have the
respective meanings assigned to them in the Pledge Agreement, dated ____________
__, 1997 (the "Pledge Agreement"), between the Company and Collateral Agent):

           a. We are familiar with the historical and current financial
           condition of the Company and each Pledged Entity including, after the
           [merger] [consolidation] [sale or transfer of all or substantially
           all assets] described in Section [7(a)(v)] of the Pledge Agreement.

           b. For the purposes of this Certificate, we have reviewed other
           financial information and forecasts relating to the Company prepared
           by the Company's management, which we believe (as to the historical
           financial information) fairly present the historical financial
           position and results of operations of the Company as of the dates and
           for the periods presented and (in the case of the forecasts) were
           based upon reasonable assumptions and provide reasonable estimations
           of future performance, although any forecasts are necessarily
           uncertain of fulfillment. We know of no facts or circumstances
           arising subsequent to the dates as of which such information and
           projections were prepared that would materially alter such
           conclusions. We have assumed that the fair saleable value of the
           Company's assets is the amount for which all the businesses of the
           Company could be sold on the date hereof either as an entirety or
           separately (including in any such sale all property and assets used
           in the business or businesses sold) and, in either case, on a going
           concern basis, without potential tax liabilities arising on sale.

           c. In addition to such review, we are familiar with and have
           considered information, [including the opinions of independent
           advisors, if any] as to the fair market values of the Company's
           assets and the probable liability, contingent or otherwise, of the
           Company to its creditors. We have estimated such values as reliably
           and as practicably as possible under the circumstances.

           Based upon the foregoing, we have reached the conclusions that, after
giving effect to the transactions contemplated by Section 7(a)(v) of the Pledge
Agreement:

           1. The Company does not intend to or believe that it has incurred or
will incur, debts that will be beyond its ability to pay as they mature.

           2. The present fair saleable value of the assets of the Company the
amount that will be required to pay the probable liability on its existing debts
(whether matured or unmatured, liquidated or unliquidated, absolute, fixed or
contingent), as they become absolute and matured. In determining "present fair
saleable value," we utilized as a guideline amounts we believe would be reached
by a willing seller and a willing buyer under no compulsion to make the sale.

           3. The Company does not have unreasonably small capital for it to
carry on its businesses as proposed to be conducted. "Unreasonably small
capital" is dependent upon the nature of the particular business or businesses
conducted or to be conducted, and the statement made in the preceding sentence
is correct based upon anticipated future conduct of the businesses of the
Company.

           4. The Company is not incurring obligations or making transfers under
any evidence of indebtedness with the intent to hinder, delay or defraud any
entity to which it is or will become indebted.

<PAGE>





after the Closing Date, the Exchange Offer Registration Statement, (ii) use its
best efforts to cause such Exchange Offer Registration Statement to become
effective at the earliest possible time, but in no event later than 120 days
after the Closing Date, (iii) in connection with the foregoing, (A) file all
pre-effective amendments to such Exchange Offer Registration Statement as may be
necessary in order to cause such Exchange Offer Registration Statement to become

commence and Consummate the Exchange Offer. The Exchange Offer shall be on the
appropriate form permitting registration of the Series B Notes to be offered in
exchange for the Series A Notes that are Transfer Restricted Securities and to
permit sales of Broker-Dealer Transfer Restricted Securities by Restricted
Broker-Dealers as contemplated by Section 3(c) below.

           (b) The Company shall use its best efforts to cause the Exchange
Offer Registration Statement to be effective continuously, and shall keep the
Exchange Offer open for a period of not less than the minimum period required
under applicable federal and state securities laws to Consummate the Exchange
Offer; provided, however, that in no event shall such period be less than 20
Business Days. The Company shall cause the Exchange Offer to comply with all

Broker-Dealer as a result of market-making activities or other trading
activities (other than Transfer Restricted Securities acquired directly from the
Company or any Affiliate of the Company) may exchange such Series A Notes
pursuant to the Exchange Offer and (ii) such Broker-Dealer may be deemed to be
an "underwriter" within the meaning of the Act and must, therefore, deliver a
prospectus meeting the requirements of the Act in connection with its initial
sale of each Series B Note received by such BrokerDealer in the Exchange Offer,
which prospectus delivery requirement may be satisfied by the delivery by such
Broker-Dealer of the Prospectus contained in the Exchange Offer Registration
Statement. Such "Plan of Distribution" section shall also contain all other
information with respect to such sales of Broker-Dealer Transfer Restricted
Securities by Restricted Broker-Dealers that the Commission may require in order
to permit such sales pursuant thereto, but such "Plan of Distribution" shall not
name any such Broker-Dealer or disclose the amount of Senior Notes held by any
such Broker-Dealer, except to the extent required by the Commission as a result
of a change in policy after the date of this Agreement.

           The Company shall use its best efforts to keep the Exchange Offer
Registration Statement continuously effective, supplemented and amended as
required by the provisions of Section 6(c) below to the extent necessary to
ensure that it is available for sales of Broker-Dealer Transfer Restricted
Securities by Restricted Broker-Dealers, and to ensure that such Registration
Statement conforms with the requirements of this Agreement, the Act and the
policies, rules and regulations of the Commission as announced from time to
time, for a period of one year from the date on which the Exchange Offer is
Consummated.

           The Company shall promptly provide sufficient copies of the latest
version of such Prospectus to such Restricted Broker-Dealers promptly upon
request, and in no event later than one day after such request, at any time
during such one-year period in order to facilitate such sales.


SECTION 4.  SHELF REGISTRATION

           (a) Shelf Registration. If (i) the Company is not required to file an
Exchange Offer Registration Statement with respect to the Series B Notes because
the Exchange Offer is not permitted by applicable law (after the procedures set
forth in Section 6(a)(i) below have been complied with) or (ii) any Holder of
Transfer Restricted Securities shall notify the Company within 20 Business Days
following the Consummation of the Exchange Offer that (A) such Holder was
prohibited by law or Commission policy from participating in the Exchange Offer
or (B) such Holder may not resell the Series B Notes acquired by it in the
Exchange Offer to the public without delivering a prospectus and the Prospectus
contained in the Exchange Offer Registration Statement is not appropriate or
available for such resales by such Holder or (C) such Holder is a Broker-Dealer
and holds Series A Notes acquired directly from the Company or one of its
affiliates, then the Company shall:

           (x) cause to be filed on or prior to 30 days after the date on which
      the Company determines that it is not required to file the Exchange Offer
      Registration Statement pursuant to clause (i) above or 30 days after the
      date on which the Company receives the notice specified in clause (ii)
      above, whichever is earlier, a shelf registration statement pursuant to
      Rule 415 under the Act (which may be an amendment to the Exchange Offer
      Registration Statement (in either event, the "Shelf Registration
      Statement")), relating to all Transfer Restricted Securities the Holders
      of which shall have provided the information required pursuant to Section
      4(b) hereof; and

           (y) use its best efforts to cause such Shelf Registration Statement
      to become effective on or prior to 30 days after the date on which the
      Company becomes obligated to file such Shelf Registration Statement.

           The Company shall use its best efforts to keep the Shelf Registration
Statement discussed in this Section 4(a) continuously effective, supplemented
and amended as required by and subject to the provisions of Sections 6(b) and
(c) hereof to the extent necessary to ensure that it is available for sales of
Transfer Restricted Securities by the Holders thereof entitled to the benefit of
this Section 4(a), and to ensure that it conforms with the requirements of this
Agreement, the Act and the policies, rules and regulations of the Commission as
announced from time to time, for a period of at least two years (as extended
pursuant to Section 6(c)(i)) following the date on which such Shelf Registration
Statement first becomes effective under the Act; provided that in the event such
applicable policies, rules and regulations of the Commission are amended to
provide for a period of less than two years, then such period shall be deemed to
be in effect for purposes of this Section 4(a).

           (b) Provision by Holders of Certain Information in Connection with
the Shelf Registration Statement. No Holder of Transfer Restricted Securities
may include any of its Transfer Restricted Securities in any Shelf Registration
Statement pursuant to this Agreement unless and until such Holder furnishes to
the Company in writing, within 20 days after receipt of a request therefor, such
information specified in item 507 of Regulation S-K under the Act for use in
connection with any Shelf Registration Statement or



<PAGE>





Prospectus or preliminary Prospectus included therein. No Holder of Transfer
Restricted Securities shall be entitled to Liquidated Damages pursuant to
Section 5 hereof unless and until such Holder shall have used its best efforts
to provide all such information. Each Holder as to which any Shelf Registration
Statement is being effected agrees to furnish promptly to the Company all
information required to be disclosed in order to make the information previously
furnished to the Company by such Holder not materially misleading.


SECTION 5.  LIQUIDATED DAMAGES

           If (i) any Registration Statement required by this Agreement is not
filed with the Commission on or prior to the date specified for such filing in
this Agreement, (ii) any such Registration Statement has not been declared
effective by the Commission on or prior to the date specified for such
effectiveness in this Agreement (the "Effectiveness Target Date"), (iii) the
Exchange Offer has not been Consummated within 30 Business Days of the
Effectiveness Target Date with respect to the Exchange Offer Registration
Statement or (iv) any Registration Statement required by this Agreement is filed
and declared effective but shall thereafter cease to be effective or fail to be
usable for its intended purpose without being succeeded immediately by a
post-effective amendment to such Registration Statement that cures such failure
and that is itself declared effective immediately (each such event referred to
in clauses (i) through (iv), a "Registration Default"), then the Company hereby
agrees to pay liquidated damages, in cash, to each Holder of Transfer Restricted
Securities with respect to the first 90-day period immediately following the
occurrence of such Registration Default, at a rate of 0.5% per annum, determined
daily, on the principal amount of the Series A Notes as of the immediately
preceding Interest Payment Date. Such interest rate will increase by an
additional 0.25% per annum at the beginning of each subsequent 90-day period up
to a maximum aggregate increase of 2.0% per annum until all Registration
Defaults have been cured, at which time the interest rate borne by the Series A
Senior Notes will be reduced to the original interest rate. Notwithstanding
anything to the contrary set forth herein, (1) upon filing of the Exchange Offer
Registration Statement (and/or, if applicable, the Shelf Registration
Statement), in the case of clause (i) above, (2) upon the effectiveness of the
Exchange Offer Registration Statement (and/or, if applicable, the Shelf
Registration Statement) in the case of clause (ii) above, (3) upon Consummation
of the Exchange Offer in the case of clause (iii) above, or (4) upon the filing
of a post-effective amendment to the Registration Statement or an additional
Registration Statement that causes the Exchange Offer Registration Statement
(and/or, if applicable, the Shelf Registration Statement) to again be declared
effective or made usable in the case of clause (iv) above, the liquidated
damages payable with respect to the Transfer Restricted Securities as a result
of such clause (i), (ii), (iii) or (iv), as applicable, shall cease.
           All accrued liquidated damages will be paid by the Company on each
Damages Payment Date to the Global Note Holder by wire transfer of immediately
available funds or by federal funds check and to Holders of Certificated
Securities by mailing checks to their registered addresses, as provided in the
Indenture. All obligations of the Company set forth in the preceding paragraph
that are outstanding with respect to any Transfer Restricted Security at the
time such security ceases to be a Transfer Restricted Security shall survive
until such time as all such obligations with respect to such security shall have
been satisfied in full.


SECTION 6.  REGISTRATION PROCEDURES

           (a)  Exchange Offer Registration Statement.  In connection with the
Exchange Offer, the Company



<PAGE>





shall comply with all applicable provisions of Section 6(c) below, shall use its
best efforts to effect such exchange and to permit the sale of Broker-Dealer
Transfer Restricted Securities being sold in accordance with the intended method
or methods of distribution thereof, and shall comply with all of the following
provisions:

                (i) If, following the date hereof there has been published a
      change in Commission policy with respect to exchange offers such as the
      Exchange Offer such that, in the reasonable opinion of counsel to the
      Company, there is a substantial question as to whether the Exchange Offer
      is permitted by applicable federal law, the Company hereby agrees to seek
      a no-action letter or other favorable decision from the Commission
      allowing the Company to Consummate an Exchange Offer for such Series A
      Notes. The Company hereby agrees to pursue the issuance of such a decision
      to the Commission staff level. In connection with the foregoing, the
      Company hereby agrees to take all such other actions as are requested by
      the Commission or otherwise required in connection with the issuance of
      such decision, including without limitation (A) participating in
      telephonic conferences with the Commission, (B) delivering to the
      Commission staff an analysis prepared by counsel to the Company setting
      forth the legal bases, if any, upon which such counsel has concluded that
      such an Exchange Offer should be permitted and (C) diligently pursuing a
      resolution (which need not be favorable) by the Commission staff of such
      submission.

                (ii) As a condition to its participation in the Exchange Offer
      pursuant to the terms of this Agreement, each Holder of Transfer
      Restricted Securities shall furnish, upon the request of the Company,
      prior to the Consummation of the Exchange Offer, a written representation
      to the Company (which may be contained in the letter of transmittal
      contemplated by the Exchange Offer Registration Statement) to the effect
      that (A) it is not an affiliate of the Company, (B) it is not engaged in,
      and does not intend to engage in, and has no arrangement or understanding
      with any person to participate in, a distribution of the Series B Notes to
      be issued in the Exchange Offer and (C) it is acquiring the Series B Notes
      in its ordinary course of business. Each Holder hereby acknowledges and
      agrees that any Broker-Dealer and any such Holder using the Exchange Offer
      to participate in a distribution of the securities to be acquired in the
      Exchange Offer (1) could not under Commission policy as in effect on the
      date of this Agreement rely on the position of the Commission enunciated
      in Morgan Stanley and Co., Inc. (available June 5, 1991) and Exxon Capital
      Holdings Corporation (available May 13, 1988), as interpreted in the
      Commission's letter to Shearman & Sterling dated July 2, 1993, and similar
      noaction letters (including, if applicable, any no-action letter obtained
      pursuant to Section 6(a) (i) and (2) must comply with the registration and
      prospectus delivery requirements of the Act in connection with a secondary
      resale transaction and that such a secondary resale transaction must be
      covered by an effective registration statement containing the selling
      security holder information required by Item 507 or 508, as applicable, of
      Regulation S-K if the resales are of Series B Notes obtained by such
      Holder in exchange for Series A Notes acquired by such Holder directly
      from the Company or an affiliate thereof.

                (iii) Prior to effectiveness of the Exchange Offer Registration
      Statement, the Company shall provide a supplemental letter to the
      Commission (A) stating that the Company is registering the Exchange Offer
      in reliance on the position of the Commission enunciated in Exxon Capital
      Holdings Corporation (available May 13, 1988), Morgan Stanley and Co.,
      Inc. (available June 5, 1991) and, if applicable, any no-action letter
      obtained pursuant to clause (i) above, (B) including a representation that
      the Company has not entered into any arrangement or understanding with any
      Person to distribute the



<PAGE>





      Series B Notes to be received in the Exchange Offer and that, to the best
      of the Company's information and belief, each Holder participating in the
      Exchange Offer is acquiring the Series B Notes in its ordinary course of
      business and has no arrangement or understanding with any Person to
      participate in the distribution of the Series B Notes received in the
      Exchange Offer and (C) any other undertaking or representation required by
      the Commission as set forth in any no-action letter obtained pursuant to
      Section 6(a)(i).

           (b) Shelf Registration Statement. In connection with the Shelf
Registration Statement, the Company shall comply with all the provisions of
Section 6(c) below and shall use its best efforts to effect such registration to
permit the sale of the Transfer Restricted Securities being sold in accordance
with the intended method or methods of distribution thereof (as indicated in the
information furnished to the Company pursuant to Section 4(b) hereof), and
pursuant thereto the Company shall prepare and file with the Commission a
Registration Statement relating to the registration on any appropriate form
under the Act, which form shall be available for the sale of the Transfer
Restricted Securities in accordance with the intended method or methods of
distribution thereof within the time periods and otherwise in accordance with
the provisions hereof.

           (c) General Provisions. In connection with any Registration Statement
and any related Prospectus required by this Agreement to permit the sale or
resale of Transfer Restricted Securities (including, without limitation, any
Exchange Offer Registration Statement and the related Prospectus, to the extent
that the same are required to be available to permit sales of Broker-Dealer
Transfer Restricted Securities by Restricted Broker-Dealers), the Company shall:

                (i) use its best efforts to keep such Registration Statement
      continuously effective and provide all requisite financial statements for
      the period specified in Section 3 or 4 of this Agreement, as applicable.
      Upon the occurrence of any event that would cause any such Registration
      Statement or the Prospectus contained therein (A) to contain a material
      misstatement or omission or (B) not to be effective and usable for resale
      of Transfer Restricted Securities during the period required by this
      Agreement, the Company shall file promptly an appropriate amendment to
      such Registration Statement, (1) in the case of clause (A), correcting any
      such misstatement or omission, and (2) in the case of clauses (A) and (B),
      use its best efforts to cause such amendment to be declared effective and
      such Registration Statement and the related Prospectus to become usable
      for their intended purpose(s) as soon as practicable thereafter;

                (ii) prepare and file with the Commission such amendments and
      post-effective amendments to the Registration Statement as may be
      necessary to keep the Registration Statement effective for the applicable
      period set forth in Section 3 or 4 hereof, or such shorter period as will
      terminate when all Transfer Restricted Securities covered by such
      Registration Statement have been sold; cause the Prospectus to be
      supplemented by any required Prospectus supplement, and as so supplemented
      to be filed pursuant to Rule 424 under the Act, and to comply fully with
      Rules 424, 430A and 462, as applicable, under the Act in a timely manner;
      and comply with the provisions of the Act with respect to the disposition
      of all securities covered by such Registration Statement during the
      applicable period in accordance with the intended method or methods of
      distribution by the sellers thereof set forth in such Registration
      Statement or supplement to the Prospectus;

                (iii)  promptly advise selling Holders and the underwriter(s),
      if any, if requested by such



<PAGE>





      Persons, confirm such advice in writing, (A) when the Prospectus or any
      Prospectus supplement or post-effective amendment has been filed, and,
      with respect to any Registration Statement or any post-effective amendment
      thereto, when the same has become effective, (B) of any request by the
      Commission for amendments to the Registration Statement or amendments or
      supplements to the Prospectus or for additional information relating
      thereto, (C) of the issuance by the Commission of any stop order
      suspending the effectiveness of the Registration Statement under the Act
      or of the suspension by any state securities commission of the
      qualification of the Transfer Restricted Securities for offering or sale
      in any jurisdiction, or the initiation of any proceeding for any of the
      preceding purposes, (D) of the existence of any fact or the happening of
      any event that makes any statement of a material fact made in the
      Registration Statement, the Prospectus, any amendment or supplement
      thereto or any document incorporated by reference therein untrue, or that
      requires the making of any additions to or changes in the Registration
      Statement in order to make the statements therein not misleading, or that
      requires the making of any additions to or changes in the Prospectus in
      order to make the statements therein, in the light of the circumstances
      under which they were made, not misleading. If at any time the Commission
      shall issue any stop order suspending the effectiveness of the
      Registration Statement, or any state securities commission or other
      regulatory authority shall issue an order suspending the qualification or
      exemption from qualification of the Transfer Restricted Securities under
      state securities or Blue Sky laws, the Company shall use its best efforts
      to obtain the withdrawal or lifting of such order at the earliest possible
      time;

                (iv) furnish to the Initial Purchaser(s), each selling Holder
      named in any Registration Statement or Prospectus and each of the
      underwriter(s) in connection with such sale, if any, before filing with
      the Commission, copies of any Registration Statement or any Prospectus
      included therein or any amendments or supplements to any such Registration
      Statement or Prospectus (including all documents incorporated by reference
      after the initial filing of such Registration Statement), which documents
      shall be subject to the review and comment of such Holders and
      underwriter(s) in connection with such sale, if any, for a period of at
      least five Business Days, and the Company shall not file any such
      Registration Statement or Prospectus or any amendment or supplement to any
      such Registration Statement or Prospectus (including, without limitation,
      all such documents incorporated by reference) to which the selling Holders
      of the Transfer Restricted Securities covered by such Registration
      Statement or the underwriter(s) in connection with such sale, if any,
      shall reasonably object within five Business Days after the receipt
      thereof. A selling Holder or underwriter, if any, shall be deemed to have
      reasonably objected to such filing if such Registration Statement,
      amendment, Prospectus or supplement, as applicable, as proposed to be
      filed, contains a material misstatement or omission or fails to comply
      with the applicable requirements of the Act;

                (v) promptly prior to the filing of any document that is to be
      incorporated by reference into a Registration Statement or Prospectus,
      provide copies of such document to the selling Holders and to the
      underwriter(s) in connection with such sale, if any, make the Company's
      representatives available for discussion of such document and other
      customary due diligence matters, and include such information in such
      document prior to the filing thereof as such selling Holders or
      underwriter(s), if any, reasonably may request;

                (vi) subject to the entry of appropriate confidentiality
      agreements, make available at reasonable times for inspection by the
      selling Holders, any managing underwriter participating in any disposition
      pursuant to such Registration Statement and any attorney or accountant
      retained by such



<PAGE>





      selling Holders or any of such underwriter(s), all financial and other
      records, pertinent corporate documents and properties of the Company and
      cause the Company's officers, directors and employees to supply all
      information reasonably requested by any such Holder, underwriter, attorney
      or accountant in connection with such Registration Statement or any
      post-effective amendment thereto subsequent to the filing thereof and
      prior to its effectiveness;

                (vii) if requested by any selling Holders or the underwriter(s)
      in connection with such sale, if any, promptly include in any Registration
      Statement or Prospectus, pursuant to a supplement or post-effective
      amendment if necessary, such information as such selling Holders and
      underwriter(s), if any, may reasonably request to have included therein,
      including, without limitation, information relating to the "Plan of
      Distribution" of the Transfer Restricted Securities, information with
      respect to the principal amount of Transfer Restricted Securities being
      sold to such underwriter(s), the purchase price being paid therefor and
      any other terms of the offering of the Transfer Restricted Securities to
      be sold in such offering; and make all required filings of such Prospectus
      supplement or post-effective amendment as soon as practicable after the
      Company is notified of the matters to be included in such Prospectus
      supplement or post-effective amendment;

                (viii) furnish to each selling Holder and each of the
      underwriter(s) in connection with such sale, if any, without charge, at
      least one copy of the Registration Statement, as first filed with the
      Commission, and of each amendment thereto, including all documents
      incorporated by reference therein and all exhibits (including, without
      limitation, all exhibits incorporated therein by reference);

                (ix) deliver to each selling Holder and each of the
      underwriter(s), if any, without charge, as many copies of the Prospectus
      (including, without limitation, each preliminary prospectus) and each
      amendment or supplement thereto as such Persons reasonably may request;
      the Company hereby consents to the use (in accordance with law) of the
      Prospectus and any amendment or supplement thereto by each of the selling
      Holders and each of the underwriter(s), if any, in connection with the
      offering and the sale of the Transfer Restricted Securities covered by the
      Prospectus or any amendment or supplement thereto;

                (x) enter into such agreements (including, without limitation,
      an underwriting agreement) and make such representations and warranties
      and take all such other actions in connection therewith in order to
      expedite or facilitate the disposition of the Transfer Restricted
      Securities pursuant to any Registration Statement contemplated by this
      Agreement as may be reasonably requested by any Holder of Transfer
      Restricted Securities or underwriter in connection with any sale or resale
      pursuant to any Registration Statement contemplated by this Agreement, and
      in such connection, whether or not an underwriting agreement is entered
      into and whether or not the registration is an Underwritten Registration,
      the Company shall:

                (A) furnish (or in the case of paragraphs (2) and (3) below, use
           its best efforts to furnish) to each selling Holder and each
           underwriter, if any, upon the effectiveness of the Shelf Registration
           Statement and to each Restricted Broker-Dealer upon Consummation of
           the Exchange Offer:

                      (1) a certificate, dated the date of Consummation of the
                Exchange Offer or the date of effectiveness of the Shelf
                Registration Statement, as the case may be, signed on behalf of
                the Company by (x) the President and (y) the Secretary, any Vice
                President or any Assistant



<PAGE>





                Secretary of the Company, confirming, as of the date thereof,
                the matters set forth in paragraphs (a), (b), (c) and (d) of
                Section 8 of the Purchase Agreement and such other similar
                matters as the Holders, underwriter(s) and/or Restricted Broker
                Dealers may reasonably request;

                      (2) an opinion, dated the date of Consummation of the
                Exchange Offer or the date of effectiveness of the Shelf
                Registration Statement, as the case may be, of counsel for the
                Company covering matters similar to those set forth in
                paragraphs (f) and (g) of Section 8 of the Purchase Agreement
                and such other matter as the Holders, underwriters and/or
                Restricted Broker Dealers may reasonably request, and in any
                event including a statement to the effect that such counsel has
                participated in conferences with officers and other
                representatives of the Company, representatives of the
                independent public accountants for the Company and have
                considered the matters required to be stated therein and the
                statements contained therein, although such counsel has not
                independently verified the accuracy, completeness or fairness of
                such statements; and that such counsel advises that, on the
                basis of the foregoing (relying as to materiality to a large
                extent upon facts provided to such counsel by officers and other
                representatives of the Company and without independent check or
                verification), no facts came to such counsel's attention that
                caused such counsel to believe that the applicable Registration
                Statement, at the time such Registration Statement or any
                post-effective amendment thereto became effective and, in the
                case of the Exchange Offer Registration Statement, as of the
                date of Consummation of the Exchange Offer, contained an untrue
                statement of a material fact or omitted to state a material fact
                required to be stated therein or necessary to make the
                statements therein not misleading, or that the Prospectus
                contained in such Registration Statement as of its date and, in
                the case of the opinion dated the date of Consummation of the
                Exchange Offer, as of the date of Consummation, contained an
                untrue statement of a material fact or omitted to state a
                material fact necessary in order to make the statements therein,
                in the light of the circumstances under which they were made,
                not misleading. Without limiting the foregoing, such counsel may
                state further that such counsel assumes no responsibility for,
                and has not independently verified, the accuracy, completeness
                or fairness of the financial statements, notes and schedules and
                other financial data included in any Registration Statement
                contemplated by this Agreement or the related Prospectus; and

                      (3) a customary comfort letter, dated as of the date of
                effectiveness of the Shelf Registration Statement or the date of
                Consummation of the Exchange Offer, as the case may be, from the
                Company's independent accountants, in the customary form and
                covering matters of the type customarily covered in comfort
                letters to underwriters in connection with primary underwritten

                Agreement.

                (B) set forth in full or incorporate by reference in the
           underwriting agreement, if any, in connection with any sale or resale
           pursuant to any Shelf Registration Statement the indemnification
           provisions and procedures of Section 8 hereof with respect to all
           parties to be indemnified pursuant to said Section; and

                (C) deliver such other documents and certificates as may be
           reasonably requested by the selling Holders, the underwriter(s), if
           any, and Restricted Broker Dealers, if any, to evidence



<PAGE>





           compliance with clause (A) above and with any customary conditions
           contained in the underwriting agreement or other agreement entered
           into by the Company pursuant to this clause (x).

           The above shall be done at each closing under such underwriting or
      similar agreement, as and to the extent required thereunder, and if at any
      time the representations and warranties of the Company contemplated in
      (A)(1) above cease to be true and correct, the Company shall so advise the
      underwriter(s), if any, the selling Holders and each Restricted
      Broker-Dealer promptly and if requested by such Persons, shall confirm
      such advice in writing;

                (xi) prior to any public offering of Transfer Restricted
      Securities, cooperate with the selling Holders, the underwriter(s), if
      any, and their counsel in connection with the registration and
      qualification of the Transfer Restricted Securities under the securities
      or Blue Sky laws of such jurisdictions as the selling Holders or
      underwriter(s), if any, may request and do any and all other acts or
      things necessary or advisable to enable the disposition in such
      jurisdictions of the Transfer Restricted Securities covered by the
      applicable Registration Statement; provided, however, that the Company
      shall not be required to register or qualify as a foreign corporation
      where it is not now so qualified or to take any action that would subject
      it to the service of process in suits or to taxation, other than as to
      matters and transactions relating to the Registration Statement, in any
      jurisdiction where it is not now so subject;

                (xii) issue, upon the request of any Holder of Series A Notes
      covered by any Shelf Registration Statement contemplated by this
      Agreement, Series B Notes having an aggregate principal amount equal to
      the aggregate principal amount of Series A Notes surrendered to the
      Company by such Holder in exchange therefor or being sold by such Holder;
      such Series B Notes to be registered in the name of such Holder or in the
      name of the purchaser(s) of such Senior Notes, as the case may be; in
      return, the Series A Notes held by such Holder shall be surrendered to the
      Company for cancellation;

                (xiii) in connection with any sale of Transfer Restricted
      Securities that will result in such securities no longer being Transfer
      Restricted Securities, cooperate with the selling Holders and the
      underwriter(s), if any, to facilitate the timely preparation and delivery
      of certificates representing Transfer Restricted Securities to be sold and
      not bearing any restrictive legends; and to register such Transfer
      Restricted Securities in such denominations and such names as the Holders
      or the underwriter(s), if any, may request at least two Business Days
      prior to such sale of Transfer Restricted Securities;

                (xiv) use their respective best efforts to cause the disposition
      of the Transfer Restricted Securities covered by the Registration
      Statement to be registered with or approved by such other governmental
      agencies or authorities as may be necessary to enable the seller or
      sellers thereof or the underwriter(s), if any, to consummate the
      disposition of such Transfer Restricted Securities, subject to the proviso
      contained in clause (xi) above;

                (xv) subject to Section 6(c)(i), if any fact or event
      contemplated by Section 6(c)(iii)(D) above shall exist or have occurred,
      prepare a supplement or post-effective amendment to the Registration
      Statement or related Prospectus or any document incorporated therein by
      reference or file any other required document so that, as thereafter
      delivered to the purchasers of Transfer Restricted Securities,



<PAGE>





      the Prospectus does not contain an untrue statement of a material fact or
      omit to state any material fact necessary to make the statements therein,
      in the light of the circumstances under which they were made, not
      misleading;

                (xvi) provide a CUSIP number for all Transfer Restricted
      Securities not later than the effective date of a Registration Statement
      covering such Transfer Restricted Securities and provide the Trustee under
      the Indenture with printed certificates for the Transfer Restricted
      Securities which are in a form eligible for deposit with the Depository
      Trust Company;

                (xvii) cooperate and assist in any filings required to be made
      with the NASD and in the performance of any due diligence investigation by
      any underwriter (including, without limitation, any "qualified independent
      underwriter") that is required to be retained in accordance with the rules
      and regulations of the NASD, and use their respective best efforts to
      cause such Registration Statement to become effective and approved by such
      governmental agencies or authorities as may be necessary to enable the
      Holders selling Transfer Restricted Securities to consummate the
      disposition of such Transfer Restricted Securities;

                (xviii) otherwise use their respective best efforts to comply
      with all applicable rules and regulations of the Commission, and make
      generally available to its security holders with regard to any applicable
      Registration Statement, as soon as practicable, a consolidated earnings
      statement meeting the requirements of Rule 158 (which need not be audited)
      covering a twelve-month period beginning after the effective date of the
      Registration Statement (as such term is defined in paragraph (c) of Rule
      158 under the Act);

                (xix) cause the Indenture to be qualified under the TIA not
      later than the effective date of the first Registration Statement required
      by this Agreement and, in connection therewith, cooperate with the Trustee
      and the Holders of Senior Notes to effect such changes to the Indenture as
      may be required for such Indenture to be so qualified in accordance with
      the terms of the TIA; and execute and use its best efforts to cause the
      Trustee to execute, all documents that may be required to effect such
      changes and all other forms and documents required to be filed with the
      Commission to enable such Indenture to be so qualified in a timely manner;
      and

                (xx) provide promptly to each Holder upon request each document
      filed with the Commission pursuant to the requirements of Section 13 or
      Section 15(d) of the Exchange Act.

           (d) Restrictions on Holders. Each Holder agrees by acquisition of a
Transfer Restricted Security that, upon receipt of notice from the Company of
the existence of any fact of the kind described in Section 6(c)(iii)(D) hereof,
such Holder shall forthwith discontinue disposition of Transfer Restricted
Securities pursuant to the applicable Registration Statement until such Holder's
receipt of the copies of the supplemented or amended Prospectus contemplated by
Section 6(c)(xv) hereof, or until it is advised in writing by the Company that
the use of the Prospectus may be resumed, and has received copies of any
additional or supplemental filings that are incorporated by reference in the
Prospectus (the "Advice"). If so directed by the Company, each Holder shall
deliver to the Company (at the Company's expense) all copies, other than
permanent file copies then in such Holder's possession, of the Prospectus
covering such Transfer Restricted Securities that was current at the time of
receipt of either such notice. In the event the Company shall give any such
notice, the time period regarding the effectiveness of such Registration
Statement set



<PAGE>





forth in Section 3 or 4 hereof, as applicable, shall be extended by the number
of days during the period from and including the date of the giving of such
notice pursuant to Section 6(c)(i) or Section 6(c)(iii)(D) hereof to and
including the date when each selling Holder covered by such Registration
Statement shall have received the copies of the supplemented or amended
Prospectus contemplated by Section 6(c)(xv) hereof or shall have received the
Advice.


SECTION 7.  REGISTRATION EXPENSES

           (a) All expenses incident to the Company's performance of or
compliance with this Agreement shall be borne by the Company, regardless of
whether a Registration Statement becomes effective, including without
limitation: (i) all registration and filing fees and expenses (including,
without limitation, with respect to filings made by any Initial Purchaser or
Holder with the NASD (and, if applicable, the fees and expenses of any
"qualified independent underwriter") and its counsel that may be required by the
rules and regulations of the NASD); (ii) all fees and expenses of compliance
with federal securities and state Blue Sky or securities laws; (iii) all
expenses of printing (including printing certificates for the Series B Notes to
be issued in the Exchange Offer and printing of Prospectuses), messenger and
delivery services and telephone; (iv) all fees and disbursements of counsel for
the Company and the Holders of Transfer Restricted Securities; (v) all
application and filing fees in connection with listing the Senior Notes on a
national securities exchange or automated quotation system pursuant to the
requirements hereof; and (vi) all fees and disbursements of independent
certified public accountants of the Company (including the expenses of any
special audit and comfort letters required by or incident to such performance).

           The Company shall, in any event, bear its internal expenses
(including, without limitation, all salaries and expenses of its officers and
employees performing legal or accounting duties), the expenses of any annual
audit and the fees and expenses of any Person, including special experts,
retained by the Company.

           (b) In connection with any Registration Statement required by this
Agreement (including, without limitation, the Exchange Offer Registration
Statement and the Shelf Registration Statement), the Company shall reimburse the
Initial Purchasers and the Holders of Transfer Restricted Securities being
tendered in the Exchange Offer and/or resold pursuant to the "Plan of
Distribution" contained in the Exchange Offer Registration Statement or

reasonable fees and disbursements of not more than one counsel, who shall be
chosen by the Holders of a majority in principal amount of the Transfer
Restricted Securities for whose benefit such Registration Statement is being
prepared.

SECTION 8.  INDEMNIFICATION

           (a) The Company and its Subsidiaries agree, jointly and severally, to
indemnify and hold harmless (i) each Holder and (ii) each person, if any, who
controls (within the meaning of Section 15 of the Act or Section 20 of the
Exchange Act) any Holder (any of the persons referred to in this clause (ii)
being hereinafter referred to as a "controlling person") and (iii) the
respective officers, directors, partners, employees, representatives and agents
of any Holder or any controlling person (any of the persons referred to in this
clause (i), (ii) or (iii) may hereinafter be referred to as an "Indemnified
Holder") to the fullest extent lawful, from and against any and all losses,
liabilities, claims, damages and expenses whatsoever (including but not limited
to attorneys' fees and any and all expenses whatsoever incurred in
investigating, preparing or defending against any investigation or litigation,
commenced or threatened, or any claim whatsoever, and any and all amounts paid
in settlement of any claim or litigation), joint or several, to which they or
any of them may become subject under the Act, the Exchange Act or otherwise,
insofar as such losses, liabilities, claims, damages or expenses (or actions in
respect thereof) arise out of or are based upon any untrue statement or alleged
untrue statement of a material fact contained in the Registration Statement, as
originally filed or any amendment thereof, or any related preliminary prospectus
or the Prospectus, or in any supplement thereto or amendment thereof, or arise
out of or are based upon the omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein, in the light of the circumstances under which they were made, not
misleading; provided that the Company and its Subsidiaries shall not be liable
in any such case to the extent, but only to the extent, that any such loss,
liability, claim, damage or expense arises out of or is based upon any such
untrue statement or alleged untrue statement or omission or alleged omission
made therein in reliance upon and in conformity with written information
furnished to the Company by or on behalf of the Holder expressly for use
therein.

           (b) Each Holder, severally and not jointly, agrees to indemnify and
hold harmless the Company and its Subsidiaries and any of their respective
directors, officers, and any person controlling (within the meaning of Section
15 of the Act or Section 20 of the Exchange Act) the Company, and the officers,
directors, partners, employees, representatives and agents of each such person,
to the same extent as the foregoing indemnity from the Company and its
Subsidiaries to each of the indemnified Holders, but only with respect to claims
and actions based on information relating to such Holder furnished in writing by
such Holder expressly for use in any Registration Statement. In case any action
or proceeding shall be brought against the Company or its Subsidiaries or any of
their respective directors or officers or any such controlling person in respect
of which indemnity may be sought against a Holder, such Holder shall have the
rights and duties given the Company and its Subsidiaries and the Company, such
Subsidiaries, such directors or officers or such controlling person shall have
the rights and duties given to each Holder by the preceding paragraph. In no
event shall any Holder be liable or responsible for any amount in excess of the
dollar amount of the proceeds received by such Holder upon its sale of the
Transfer Restricted Securities giving rise to such indemnification obligation.

           (c) Promptly after receipt by an indemnified party under subsection
(a) or (b) above of notice of the commencement of any action, such indemnified
party shall, if a claim in respect thereof is to be made against the
indemnifying party under such subsection, notify each party against whom
indemnification is to be sought in writing of the commencement thereof (but the
failure so to notify an indemnifying party shall not relieve it from any
liability which it may have under this Section 8 except to the extent that it
has been prejudiced in any material respect by such failure or from any
liability which it may otherwise have). In case



<PAGE>





any such action is brought against any indemnified party, and it notifies an
indemnifying party of the commencement thereof, the indemnifying party shall be
entitled to participate therein, and to the extent it may elect by written
notice delivered to the indemnified party promptly after receiving the aforesaid
notice from such indemnified party, to assume the defense thereof with counsel
reasonably satisfactory to such indemnified party. Notwithstanding the
foregoing, the indemnified party or parties shall have the right to employ its
or their own counsel in any such case, but the fees and expenses of such counsel
shall be at the expense of such indemnified party or parties unless (i) the
employment of such counsel shall have been authorized in writing by the
indemnifying parties in connection with the defense of such action, (ii) the
indemnifying parties shall not have employed counsel reasonably satisfactory to
the indemnified party to take charge of the defense of such action within a
reasonable time after notice of commencement of the action, or (iii) such
indemnified party or parties shall have reasonably concluded that there may be
defenses available to it or them which are different from or additional to those
available to one or all of the indemnifying parties (in which case the
indemnifying party or parties shall not have the right to direct the defense of
such action on behalf of the indemnified party or parties), in any of which
events such fees and expenses of counsel shall be borne by the indemnifying
parties. The indemnifying party under subsection (a) or (b) above, shall only be
liable for the legal expenses of one counsel (in addition to any local counsel)
for all indemnified parties in each jurisdiction in which any claim or action is
brought; provided that the indemnifying party shall be liable for separate
counsel for any indemnified party in a jurisdiction, if counsel to the
indemnified parties shall have reasonably concluded that there may be defenses
available to such indemnified party that are difference from or additional to
those available to one or more of the other indemnified parties and that
separate counsel for such indemnified party is prudent under the circumstances.
 Anything in this subsection to the contrary notwithstanding, an indemnifying
party shall not be liable for any settlement of any claim or action effected
without its prior written consent; provided that such consent was not
unreasonably withheld.

           (d) In order to provide for contribution in circumstances in which
the indemnification provided for in this Section 8 is for any reason held to be
unavailable from the Company or is insufficient to hold harmless a party
indemnified thereunder, the Company and each Holder shall contribute to the
aggregate losses, claims, damages, liabilities and expenses of the nature
contemplated by such indemnification provision (including, without limitation,
any investigation, legal and other expenses incurred in connection with, and any
amount paid in settlement of, any action, suit or proceeding or any claims
asserted, but after deducting in the case of losses, claims, damages,
liabilities and expenses suffered by the Company, any contribution received by
the Company from persons, other than the Holder, who may also be liable for
contribution, including, without limitation, persons who control the Company
within the meaning of Section 15 of the Act or Section 20(a) of the Exchange
Act) to which the Company and one or more of the Holders may be subject, in such
proportion as is appropriate to reflect the relative benefits received by the
Company and the Holder or, if such allocation is not permitted by applicable law
or indemnification is not available as a result of the indemnifying party not
having received notice as provided in this Section 8, in such proportion as is
appropriate to reflect not only the relative benefits referred to above but also
the relative fault of the Company and the Holder in connection with the
statements or omissions which resulted in such losses, claims, damages,
liabilities or expenses, as well as any other relevant equitable considerations.
The Company and the Holders agree that it would not be just and equitable if
contribution pursuant to this Section 8 were determined by pro rata allocation
or by any other method of allocation which does not take into account the
equitable considerations referred to above. Notwithstanding the provisions of
this Section 8, (i) no Holder or its related indemnified Holders shall be
required to contribute, in the aggregate, any amount in excess of the amount by
which the total proceeds received by such Holder with respect to the sale of its



<PAGE>





Transfer Restricted Securities pursuant to a Registration Statement exceeds the
sum of (A) the amount paid by such Holder for such Transfer Restricted
Securities plus (B) the amount of any damages which such Holder has otherwise
been required to pay by reason of such untrue or alleged untrue statement or
omission or alleged omission and (ii) 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 Holders' obligations to contribute pursuant to this
Section 8(c) are several in proportion to the respective principal amount of
Series A Notes held by each of the Holders hereunder and not joint.

           For purposes of this Section 8(d), (A) each person, if any, who
controls any Holder within the meaning of Section 15 of the Act or Section 20(a)
of the Exchange Act and (B) the respective officers, directors, partners,
employees, representatives and agents of any Holder or any controlling person
shall have the same rights to contribution as such Holder, and each person, if
any, who controls the Company within the meaning of Section 15 of the Act or
Section 20(a) of the Exchange Act shall have the same rights to contribution as
the Company, subject in each case to clauses (i) and (ii) of this Section 8(d).
Any party entitled to contribution shall, promptly after receipt of notice of
commencement of any action, suit or proceeding against such party in respect of
which a claim for contribution may be made against another party or parties
under this Section 8, notify such party or parties from whom contribution may be
sought, but the failure to so notify such party or parties shall not relieve the
party or parties from whom contribution may be sought from any obligation it or
they may have under this Section 8 or otherwise. No party shall be liable for
contribution with respect to any action or claim settled without its prior
written consent; provided that such written consent was not unreasonably
withheld.


SECTION 9.      RULE 144A

           The Company hereby agrees with each Holder, for so long as any
Transfer Restricted Securities remain outstanding and during any period in which
the Company is not subject to Section 13 or 15(d) of the Securities Exchange
Act, to make available, upon request of any Holder of Transfer Restricted
Securities, to any Holder or beneficial owner of Transfer Restricted Securities
in connection with any sale thereof and any prospective purchaser of such
Transfer Restricted Securities designated by such Holder or beneficial owner,
the information required by Rule 144A(d)(4) under the Act in order to permit
resales of such Transfer Restricted Securities pursuant to Rule 144A.


SECTION 10.  UNDERWRITTEN REGISTRATIONS

           No Holder may participate in any Underwritten Registration hereunder
unless such Holder (a) agrees to sell such Holder's Transfer Restricted
Securities on the basis provided in customary underwriting arrangements entered
into in connection therewith and (b) completes and executes all reasonable
questionnaires, powers of attorney, and other documents required under the terms
of such underwriting arrangements.





<PAGE>





SECTION 11.  SELECTION OF UNDERWRITERS

           For any Underwritten Offering, the investment banker or investment
bankers and manager or managers for any Underwritten Offering that will
administer such offering will be selected by the Holders of a majority in
aggregate principal amount of the Transfer Restricted Securities included in
such offering. Such investment bankers and managers are referred to herein as
the "underwriters."


SECTION 12.  MISCELLANEOUS

           (a) Remedies. Each Holder, in addition to being entitled to exercise
all rights provided herein, in the Indenture, the Purchase Agreement or granted
by law, including recovery of liquidated or other damages, will be entitled to
specific performance of its rights under this Agreement. The Company agrees that
monetary damages would not be adequate compensation for any loss incurred by
reason of a breach by them of the provisions of this Agreement and hereby agree
to waive the defense in any action for specific performance that a remedy at law
would be adequate.

           (b) No Inconsistent Agreements. The Company shall not, on or after
the date of this Agreement, enter into any agreement with respect to its
securities that is inconsistent with the rights granted to the Holders in this
Agreement or otherwise conflicts with the provisions hereof. The Company has not
previously entered into any agreement granting any registration rights with
respect to its securities to any Person other than pursuant to (i) the MCI
Preferred Provider Agreement (as defined in the Offering Memorandum, dated
August 21, 1997, relating to the Series A Notes (the "Offering Memorandum")),
(ii) that certain Equity and Contribution Agreement between the Company and
Lenfest Telephony, dated August 4, 1997 and (iii) as set forth in the Offering
Memorandum. The rights granted to the Holders 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 agreement in effect on the date hereof.

           (c) Adjustments Affecting the Senior Notes. The Company shall not
take any action, or voluntarily permit any change to occur, with respect to the
Senior Notes that would materially and adversely affect the ability of the
Holders to Consummate any Exchange Offer.

           (d) Amendments and Waivers. The provisions of this Agreement may not
be amended, modified or supplemented, and waivers or consents to or departures
from the provisions hereof may not be given unless (i) in the case of Section 5
hereof and this Section 12(d)(i), the Company has obtained the written consent
of Holders of all outstanding Transfer Restricted Securities and (ii) in the
case of all other provisions hereof, the Company has obtained the written
consent of Holders of a majority of the outstanding principal amount of Transfer
Restricted Securities. Notwithstanding the foregoing, a waiver or consent to
departure from the provisions hereof that relates exclusively to the rights of
Holders whose securities are being tendered pursuant to the Exchange Offer and
that does not affect directly or indirectly the rights of other Holders whose
securities are not being tendered pursuant to such Exchange Offer may be given
by the Holders of a majority of the outstanding principal amount of Transfer
Restricted Securities subject to such Exchange Offer.

           (e)  Notices.  All notices and other communications provided for or
permitted hereunder shall be made in writing by hand-delivery,  first-class mail

                    PLEDGE, ESCROW AND DISBURSEMENT AGREEMENT


                  THIS PLEDGE, ESCROW AND DISBURSEMENT AGREEMENT (this
"Agreement"), dated as of August 27, 1997, is by and among HYPERION
TELECOMMUNICATIONS, INC. (the "Company"), Bank of Montreal Trust Company, as
trustee under the Indenture referred to below (the "Trustee"), and Bank of
Montreal Trust Company, in its capacity as collateral agent for the Trustee and
the Holders of the Notes hereinafter described (the "Escrow Agent").

                                    RECITALS

         A. The Notes. Pursuant to that certain Indenture (the "Indenture")
dated as of August 27, 1997, by and between the Company and the Trustee, the
Company will issue $250,000,000 in aggregate principal amount of 12 1/4% Senior
Secured Notes due 2004 (collectively, the "Notes"). Immediately after receipt of
payment for the Notes (the "Deposit Time"), the Company will deposit $83,400,000
of the net proceeds from the sale of the Notes (the "Escrow Proceeds") into a
segregated cash collateral trust account with the Escrow Agent at its office at
77 Water Street, New York, New York, in the name of Bank of Montreal Trust
Company, as Escrow Agent, "Collateral Account for Hyperion Telecommunications,
Inc." (the "Escrow Account"). The Escrow Account and all balances and
investments from time to time therein shall be under the sole dominion and
control of the Escrow Agent for the benefit of the Holders of the Notes.
Capitalized terms used but not defined herein shall have the meanings assigned
to them in the Indenture.

         B.       Purpose.  The parties hereto desire to set forth their
agreement with regard to the administration of the Escrow Account,  the creation
of a security  interest in the Collateral (as defined herein) and the conditions
upon which funds will be  released  from the Escrow  Account and the  conditions
upon which the security interest and Lien described herein will be released.

                                    AGREEMENT

                  NOW, THEREFORE, for good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, the parties hereto
agree as follows:

         1.       Security Interest.

                  1.1 Pledge and Assignment. The Company hereby irrevocably
pledges, assigns and sets over to the Trustee, and grants to the Trustee, for
the benefit of the Holders of the Notes, a first priority continuing security
interest in all of the Company's right, title and interest to all of the
following, whether now owned or existing or hereafter acquired or created
(collectively, the "Collateral"):

                           1.1.1 the Escrow Account;

                           1.1.2 all funds from time to time held in the Escrow
         Account, including, without limitation, the Escrow Proceeds and all
         certificates and instruments, if any, from time to time, representing
         or evidencing the Escrow Account or the Escrow Proceeds;

                           1.1.3 all Allowable Investments (as defined herein),
         whether the same shall constitute certificated securities,
         uncertificated securities, investment property, instruments, general
         intangibles or otherwise held by or registered in the name of the
         Escrow Agent or the Trustee and all certificates and instruments, if
         any, from time to time representing or



<PAGE>



         evidencing the Allowable Investments;

                           1.1.4 all notes, certificates of deposit, deposit
         accounts, checks and other instruments from time to time hereafter
         delivered to or otherwise possessed by the Trustee or the Escrow Agent
         for or on behalf of the Company in substitution for or in addition to
         any or all of the then existing Collateral;

                           1.1.5 all interest, dividends, cash, instruments and
         other property from time to time received, receivable or otherwise
         distributed in respect of or in exchange for any or all of the then
         existing Collateral; and

                           1.1.6 all proceeds of the foregoing including,
         without limitation, cash proceeds.

The Company and the Trustee hereby appoint the Escrow Agent to act as the
Trustee's agent, on behalf of the Holders of the Notes, for purposes of
perfecting the foregoing pledge, assignment and security interest in the
Collateral, and the Escrow Agent hereby accepts such appointment. The Escrow
Agent hereby acknowledges the security interest in the Collateral granted by the
Company in favor of the Trustee hereunder. Escrow Agent further acknowledges
that it is holding the Collateral for the Company subject to the pledge and
security interest granted to the Trustee hereunder. Without prejudice to the
Trustee's rights under Section 7.07 of the Indenture, for so long as the
foregoing pledge, assignment and security interest remains in effect, the Escrow
Agent hereby waives any right of setoff or banker's lien that it, in its
individual capacity, may have with respect to any or all of the Collateral.

                  1.2 Secured Obligations. This Agreement secures the due and
punctual payment and performance of all obligations and indebtedness of the
Company, whether now or hereafter existing, under the Notes and the Indenture
including, without limitation, interest accrued thereon after the commencement
of a bankruptcy, reorganization or similar proceeding involving the Company to
the extent permitted by applicable law (collectively, the "Secured
Obligations").

                  1.3 Delivery of Collateral. All certificates or instruments,
if any, representing or evidencing the Collateral shall be held by or on behalf
of the Escrow Agent pursuant hereto and shall be in suitable form for transfer
by delivery, or shall be accompanied by duly executed instruments of transfer or
assignments in blank, all in form and substance reasonably satisfactory to the
Trustee and the Escrow Agent. All securities in uncertificated or book-entry
form, if any, representing or evidencing the Collateral shall be registered in
the name of the Trustee or any of its nominees by book-entry or as otherwise
appropriate so as to properly identify the interest of the Trustee therein. In
addition, the Trustee shall have the right, at any time following the occurrence
of an Event of Default, and only for so long as such Event of Default is
continuing, to transfer to or to register in the name of the Trustee or any of
its nominees any or all other Collateral. Except as otherwise provided herein,
all Collateral shall be deposited and held in the Escrow Account. The Trustee
shall have the right at any time to exchange certificates or instruments
representing or evidencing all or any portion of the Collateral for certificates
or instruments of smaller or larger denominations in the same aggregate amount.

                  1.4 Further Assurances. Prior to, contemporaneously herewith,
and at any time and from time to time hereafter, the Company shall, at the
Company's expense, execute and deliver to the Trustee or the Escrow Agent such
other instruments and documents, and shall take all further action as it deems
necessary or advisable or as the Trustee or the Escrow Agent may reasonably
requests, including, without limitation, an Opinion of Counsel, upon which the
Trustee or the Escrow Agent, as the case may be, may conclusively rely, to
confirm or perfect the security interest of the Trustee granted or purported to
be granted



<PAGE>



hereby or to enable the Trustee to exercise and enforce its rights and remedies
hereunder with respect to any Collateral, and the Company shall take all
necessary action to preserve and protect the security interest created hereby as
a first priority, perfected lien and encumbrance upon the Collateral. The
Company shall pay all costs incurred in connection with any of the foregoing.

                  1.5      Maintaining the Escrow Account.  So long as this
         Agreement is in full force and effect:

                           1.5.1 the Company shall establish and maintain the
         Escrow Account with the Escrow Agent in New York, New York, and the
         Escrow Account shall at all times remain under the exclusive dominion
         and control of the Escrow Agent for the benefit of the Holders of the
         Notes; and

                           1.5.2 it shall be a term and condition of the Escrow
         Account, notwithstanding any term or condition to the contrary in any
         other agreement relating to the Escrow Account and except as otherwise
         provided by the provisions of Article 3 of this Agreement, that no
         amount (including, without limitation, interest on or other proceeds of
         the Escrow Account or on any Allowable Investments held therein) shall
         be paid or released to or for the account of, or withdrawn by or for
         the account of, the Company or any other person or entity other than
         the Trustee from the Escrow Account.

                  1.6 Transfers and Other Liens. Until termination of this
Agreement pursuant to Section 8, the Company agrees that it shall not (i) sell,
assign (by operation of law or otherwise) or otherwise dispose of, or grant any
option with respect to, any of the Collateral or (ii) create or permit to exist
any Lien upon or with respect to any of the Collateral, except for the security
interest under this Agreement.

                  1.7 Attorneys-in-Fact. In addition to all of the powers
granted to the Trustee pursuant to Article 6 of the Indenture, the Company
hereby irrevocably appoints each of the Trustee and the Escrow Agent as the
Company's attorney-in-fact, coupled with an interest, with full authority in the
place and stead of the Company and in the name of the Company or otherwise, from
time to time in the Trustee's or the Escrow Agent's discretion to, so long as
any Event of Default has occurred and is continuing, take any action and to
execute any instrument which the Trustee or the Escrow Agent may deem necessary
or advisable to accomplish the purposes of this Agreement, including, without
limitation, to receive, endorse and collect all instruments made payable to the
Company representing any interest payment, dividend or other distribution in
respect of the Collateral or any part thereof and to give full discharge for the
same, and the expenses of the Trustee incurred in connection therewith shall be
payable by the Company.

                  1.8 Trustee May Perform. Without limiting the authority
granted under Section 1.7 and except with respect to the failure of the Company
to deliver investment instructions, which shall be governed by the second
paragraph of Section 2.1 hereof, if the Company fails to perform any agreement
contained herein, the Trustee or the Escrow Agent may, but shall not be
obligated to, itself perform, or cause performance of, such agreement, and the
expenses of the Trustee or the Escrow Agent incurred in connection therewith
shall be payable by the Company. In the event that the Trustee or the Escrow
Agent perform pursuant to this Section 1.8, the Company shall compensate,
reimburse and indemnify the Trustee or the Escrow Agent, as the case may be, in
the manner provided in Section 7.07 of the Indenture.

                  1.9      Escrow Account Statement.  Each month, the Escrow
Agent  shall  deliver  to the  Company  and the  Trustee a  statement  in a form
satisfactory  to the  Company  and the  Trustee  setting  forth with  reasonable
particularity  the balance of funds then in the Escrow Account and the manner in
which such



<PAGE>



funds are invested. The parties hereto irrevocably instruct the Escrow Agent
that on the first date upon which the balance in the Escrow account is reduced
to zero, the Escrow Agent shall deliver to the Company and to the Trustee a
notice that the balance in the Escrow Account has been reduced to zero.

         2.       Investment and Liquidation of Funds in Escrow Account.  Funds
deposited in the Escrow  Account shall be invested and  reinvested by the Escrow
Agent on the following terms and conditions:

                  2.1 Allowable Investments. Subject to the provisions of
Articles 2 and 3, funds held by the Escrow Agent in the Escrow Account may, at
the written direction of the Company, be invested and reinvested solely in the
following ("Allowable Investments"): (i) fixed rate obligations of, or
obligations guaranteed by, the United States of America for the payment of which
guarantee or obligations the full faith and credit of the United States of
America is pledged ("Government Securities") having a maturity date on or before
the date on which the payments of interest on the Notes to which such Government
Securities are pledged to secure occur and (ii) shares of any money market
mutual fund or similar fund, in each case, having assets in excess of $500
million which invests solely in Government Securities.

                  If the Company fails to give written investment instructions
to the Escrow Agent by 10:00 a.m. (New York time) on any Business Day (other
than the Closing Date) on which there is uninvested cash and/or maturing
Allowable Investments in the Escrow Account, the Trustee is hereby authorized
and directed to direct the Escrow Agent to, and the Escrow Agent shall, invest
any such cash or the proceeds of any maturing Allowable Investments in Allowable
Investments maturing on the next Business Day. On the Closing Date, the Company
may direct the Trustee, who shall direct the Escrow Agent, to invest the
proceeds in the Escrow Account in Allowable Investments until 2:00 p.m., which
instructions shall be executed no later than 12:00 noon on the Business Day
immediately following the Closing Date. The Company's failure to give such
investment instructions shall not constitute a default or an event of default
hereunder.

                  2.2 Interest. All interest earned on funds invested in
Allowable Investments shall be held in the Escrow Account and reinvested in
accordance with the terms hereof and shall be subject to the security interest
granted hereunder to the Trustee.

                  2.3 Limitation of Trustee's and Escrow Agent's Liability.
Subject to Section 9.12, in no event shall the Trustee or the Escrow Agent have
any liability to the Company or any other Person for investing the funds from
time to time in the Escrow Account in accordance with the provisions of this
Article 2, regardless of whether greater income or a higher yield could have
been obtained had the Escrow Agent invested such funds in different Allowable
Investments, or for any loss (including breakage costs or loss of principal)
associated with the sale or liquidation of Allowable Investments in accordance
with the terms of this Agreement.

                  2.4 Liquidation of Funds. In liquidating any Allowable
Investments in accordance with Article 3 of this Agreement, the Company shall
direct the Trustee or the Escrow Agent as to which Allowable Investments shall
be liquidated.

                                                     3.       Interest Payments.

                  3.1 Not later than five (5) Business Days prior to the date of
each of the first six scheduled interest payments due on the Notes, the Company
shall, in writing, direct the Escrow Agent to transfer from the Escrow Account
to the Paying Agent funds necessary to provide for payment in full or any
portion of the next scheduled interest payment on the Notes or, if the Company
does not intend to utilize the funds in the Escrow Account for such payment of
interest, then the Company shall comply with Section 3.2



<PAGE>



below. Upon receipt of such written request, the Escrow Agent shall take any
action necessary to provide for the payment of such interest payment on the
Notes directly to the Holders of Notes from proceeds of the Collateral in the
Escrow Account. Concurrently with any release of funds to the Paying Agent
pursuant to this Section 3.1, the Company shall deliver to the Trustee a
certificate substantially in the form of Exhibit A hereto.

                  3.2 If the Company makes any interest payment or portion of an
interest payment from a source of funds other than the Escrow Account ("Company
Funds"), the Company may, after payment in full of such interest payment, direct
the Trustee in writing to direct the Escrow Agent to release to the Company or
at the direction of the Company an amount of funds from the Escrow Account equal
to the lesser of (i) the amount of Company Funds so expended and (ii) the amount
of funds in the Escrow Account which exceeds the amount sufficient, in the
reasonable opinion of the Trustee, to provide for payment in full of the first
six scheduled interest payments on the Notes less than or equal to the amount of
Company Funds so expended. Upon receipt of the certificate described in the
following sentence, the Trustee shall direct the Escrow Agent to pay over to the
Company the requested amount. Concurrently with any release of funds to the
Company pursuant to this Section 3.2, the Company shall deliver to the Trustee a
certificate substantially in the form of Exhibit A hereto.

                  3.3 Upon payment in full of the first six scheduled interest
payments on the Notes, the security interest in the Collateral evidenced by this
Agreement shall terminate and be of no further force and effect. Furthermore,
upon the release of any Collateral from the Escrow Account in accordance with
the terms of this Agreement, whether upon release of Collateral to Holders as
payment of interest, to the Company or otherwise, the security interest
evidenced by this Agreement in the Collateral so released shall terminate and be
of no further force and effect.

         4.       Representations and Warranties.  The Company hereby represents
and warrants that:

                  4.1 The execution, delivery and performance by the Company of
this Agreement are within the Company's corporate powers, have been duly
authorized by all necessary corporate action, and do not contravene, or
constitute a default under, any provision of applicable law or regulation or of
the certificate of incorporation of the Company or of any agreement, judgment,
injunction, order, decree or other instrument binding upon the Company or result
in the creation or imposition of any Lien on any assets of the Company, except
for the security interests granted under this Agreement.

                  4.2 The Company is the record and beneficial owner of the
Collateral, free and clear of any and all Liens or claims of any person or
entity (except for the security interests granted under this Agreement). No
financing statement covering the Collateral is on file in any public office
other than the financing statements filed pursuant to this Agreement.

                  4.3 This Agreement has been duly executed and delivered by the
Company and constitutes a legal, valid and binding obligation of the Company,
enforceable against the Company in accordance with its terms, except as such
enforceability may be limited by the effect of any applicable bankruptcy,
insolvency, reorganization, moratorium or other similar laws affecting
creditors' rights generally or general principles of equity and commercial
reasonableness.

                  4.4 Upon the filing of financing statements required by the
Uniform Commercial Code (the "UCC"), the pledge of the Collateral pursuant to
this Agreement creates a valid and perfected first priority security interest in
and to the Collateral, securing the payment of the Secured Obligations for the
benefit of the Trustee and the ratable benefit of the Holders of Notes,
enforceable as such against all creditors of the



<PAGE>



Company and any persons purporting to purchase any of the Collateral from the
Company other than as permitted by the Indenture.

                  4.5 No consent of any other Person and no consent,
authorization, approval, or other action by, and no notice to or filing with,
any governmental authority or regulatory body is required either (1) for the
pledge by the Company of the Collateral pursuant to this Agreement or for the
execution, delivery or performance of this Agreement by the Company (except for
any filings necessary to perfect Liens on the Collateral) or (2) for the
exercise by the Trustee of the rights provided for in this Agreement or the
remedies in respect of the Collateral pursuant to this Agreement.

                  4.6 No litigation, investigation or proceeding of or before
any arbitrator or governmental authority is pending or, to the knowledge of the
Company, threatened by or against the Company with respect to this Agreement or
any of the transactions contemplated hereby.

                  4.7 The pledge of the Collateral pursuant to this Agreement is
not prohibited by any applicable law or governmental regulation, release,
interpretation or opinion of the Board of Governors of the Federal Reserve
System or other regulatory agency (including, without limitation, Regulations G,
T, U and X of the Board of Governors of the Federal Reserve System).

         5.       Covenants

                  The Company covenants and agrees with the Escrow Agent, the
Trustee and the Holders of Notes from and after the date of this Agreement until
the earlier of payment in full in cash of (A) each of the first six scheduled
interest payments due on the Notes under the terms of the Indenture or (B) all
obligations (including, but not limited to all Obligations) due and owing under
the Indenture and the Notes in the event such obligations (including, but not
limited to all Obligations) become due and payable prior to the payment of the
first six scheduled interest payments on the Notes:

                  (i) The Company agrees that it shall not (a) sell or otherwise
         dispose of, or grant any option or warrant with respect to, any of the
         Collateral or (b) create or permit to exist any Lien upon or with
         respect to any of the Collateral (except for the lien created pursuant
         to this Agreement) and, except as otherwise provided in this Agreement,
         at all times shall be the sole beneficial owner of the Collateral.

                  (ii) The Company agrees that it shall not (a) enter into any
         agreement or understanding that purports to or may restrict or inhibit
         the Trustee's rights or remedies hereunder, including, without
         limitation, the Trustee's right to sell or otherwise dispose of the
         Collateral in accordance with the terms of this Agreement or (b) fail
         to pay or discharge any tax, assessment or levy of any nature not later
         than five days prior to the date of any proposed sale under any
         judgement, writ or warrant of attachment with regard to the Collateral.

                  6. Remedies upon Default.  If any Event of Default shall have
occurred and be continuing:

                  (i) The Trustee may, without notice to the Company except as
         required by law and at any time or from time to time, direct the Escrow
         Agent to liquidate all Allowable Investments and transfer all funds in
         the Escrow Account to the Trustee or the Paying Agent to apply such
         funds in accordance with the provisions of the Indenture.

                  (ii)     The Escrow Agent and/or the Trustee may also exercise
         in respect of the Collateral,



<PAGE>



         in addition to the other rights and remedies provided for herein or
         otherwise available to it, all the rights and remedies of a secured
         party on default under the Uniform Commercial Code in effect at that
         time in the State of New York (the "Code") (whether or not the Code
         applies to the affected Collateral), and may also, without notice
         except as specified below, sell the Collateral or any part thereof in
         one or more parcels at public or private sale, at any of the Trustee's
         or the Escrow Agent's offices or elsewhere, for cash, on credit or for
         future delivery, and upon such other terms as the Trustee may deem
         commercially reasonable. The Company agrees that, to the extent notice
         of sale shall be required by law, at least ten days' notice to the
         Company of the time and place of any public sale or the time after
         which any private sale is to be made shall constitute reasonable
         notification. The Trustee and the Escrow Agent shall not be obligated
         to make any sale of Collateral regardless of notice of sale having been
         given. The Trustee or the Escrow Agent may adjourn any public or
         private sale from time to time by announcement at the time and place
         fixed therefor, and such sale may, without further notice, be made at
         the time and place to which it was so adjourned.

                  (iii) Any cash held by the Escrow Agent as Collateral and all
         net cash proceeds received by the Trustee or the Escrow Agent in
         respect of any sale or liquidation of, collection from, or other
         realization upon all or any part of the Collateral may, in the
         discretion of the Trustee, be held by the Trustee or the Escrow Agent
         as collateral for, and/or then or at any time thereafter be applied
         (after payment of any costs and expenses incurred in connection with
         any sale, liquidation or disposition of or realization upon the
         Collateral and the payment of any amounts payable to the Trustee or the
         Escrow Agent) in whole or in part by the Trustee or the Escrow Agent
         for the ratable benefit of the Holders of the Notes against, all or any
         part of the Secured Obligations in such order as the Trustee shall
         elect. Any surplus of such cash or cash proceeds held by the Trustee or
         the Escrow Agent and remaining after payment in full of all the Secured
         Obligations and the costs and expenses incurred by and amounts payable
         to the Trustee or the Escrow Agent hereunder or under the Indenture
         shall be paid over to the Company or to whomsoever shall be lawfully
         entitled to receive such surplus.

                  7.       Indemnity and Authority of the Escrow Agent.

                           7.1 The Escrow Agent shall have and be entitled to
         exercise all powers hereunder that are specifically granted to the
         Escrow Agent by the terms hereof, together with such powers as are
         reasonably incident thereto. The Escrow Agent may perform any of its
         duties hereunder or in connection with the Escrow Account by or through
         agents or employees and shall be entitled to retain counsel of its
         choice and to act in reliance upon the advice of such counsel
         concerning all such matters. Neither the Escrow Agent nor any director,
         officer, employee, attorney or agent of the Escrow Agent (each, an
         "Indemnified Person") shall be responsible for the validity,
         effectiveness or sufficiency hereof or of any document or security
         furnished pursuant hereto. The Escrow Agent and its directors,
         officers, employees, attorneys and agents shall be entitled to rely on
         any communication, instrument or document believed by it or them to be
         genuine and correct and to have been signed or sent by the proper
         person or persons. The Company agrees to indemnify and hold harmless
         the Escrow Agent and each Indemnified Person from and against any and
         all costs, expenses (including the reasonable fees and disbursements of
         counsel (including the reasonably allocated costs of inside counsel)),
         claims and liabilities incurred by the Escrow Agent or such Indemnified
         Person hereunder, unless such claim or liability shall be due to
         willful misconduct or gross negligence on the part of the Escrow Agent
         or such Indemnified Person.

                           7.2 The Company acknowledges that the rights and
         responsibilities of the Escrow Agent under this Agreement with respect
         to any action taken by the Escrow Agent or the exercise or non-exercise
         by the Escrow Agent of any option, right, request, judgment or other
         right



<PAGE>



         or remedy provided for herein or resulting or arising out of this
         Agreement shall be governed by the Indenture and, as between the Escrow
         Agent and the Company, the Escrow Agent shall be conclusively presumed
         to be acting as agent for the Trustee with full and valid authority so
         to act or refrain from acting, and the Company shall not be obligated
         or entitled to make any inquiry respecting such authority.

                           7.3 No provision of this Agreement shall require the
         Trustee to expend or risk its own funds or incur any liability. The
         Trustee shall be under no obligation to exercise any of its rights and
         powers under this Agreement at the request of any Holders, unless such
         Holder shall have offered to the Trustee security and indemnity
         satisfactory to it against any loss, liability or expense.

                  8.       Termination.

                  8.1 This Agreement shall create a continuing security interest
in and to the Collateral and such security interest shall, unless otherwise
provided in the Indenture or in this Agreement, remain in full force and effect
until the earlier of payment in full in cash of (A) each of the first six
scheduled interest payments due on the Notes under the terms of the Indenture or
(B) all obligations (including, but not limited to, all Obligations) due and
owing under the Indenture and the Notes in the event such obligations become
payable prior to the payment of the first six scheduled interest payments on the
Notes. This Agreement shall be binding upon the Company, its successors and
assigns, and shall inure, together with the rights and remedies of the Trustee
hereunder, to the benefit of the Trustee, the Escrow Agent, the Holders of Notes
and their respective successors, transferees and assigns.

                  8.2 Subject to the provisions of Section 9.3 hereof, this
Agreement shall terminate upon the earlier of payment in full in cash of (A)
each of the first six scheduled interest payments due on the Notes under the
terms of the Indenture or (B) all obligations (including, but not limited to,
all Obligations) due and owing under the Indenture and the Notes in the event
such obligations (including, but not limited to all Obligations) become payable
prior to the payment of the first six scheduled interest payments on the Notes.
At such time, the Trustee shall, at the written request of the Company, reassign
and redeliver to the Company all of the Collateral hereunder that has not been
sold, disposed of, retained or applied by the Trustee in accordance with the
terms of this Agreement and the Indenture. Such reassignment and redelivery
shall be without warranty (either express or implied) by or recourse to the
Trustee, except as to the absence of any prior assignments by or encumbrances
created by the Trustee on its interest in the Collateral, and shall be at the
expense of the Company.

         9.       Miscellaneous.

                  9.1 Waiver. Either party hereto may specifically waive any
breach of this Agreement by any other party, but no such waiver shall be deemed
to have been given unless such waiver is in writing, signed by the waiving
party, and specifically designates the breach waived, nor shall any such waiver
constitute a continuing waiver of similar or other breaches.

                  9.2 Invalidity. If, for any reason whatsoever, any one or more
of the provisions of this Agreement shall be held or deemed to be inoperative,
unenforceable or invalid in a particular case or in all cases, such
circumstances shall not have the effect of rendering any of the other provisions
of this Agreement inoperative, unenforceable or invalid, and the inoperative,
unenforceable or invalid provision shall be construed as if it were written so
as to effectuate, to the maximum extent possible, the parties' intent.

                  9.3      Survival of Provisions.  All representations,
warranties and covenants of the



<PAGE>



Company contained herein shall survive the execution and delivery of this
Agreement, and shall terminate only upon the termination of this Agreement;
provided, however, that the Company's obligations pursuant to Section 7 hereof
shall survive the termination of this Agreement (including any termination under
applicable bankruptcy laws) or the resignation or removal of the Trustee or the
Escrow Agent.

                  9.4 Assignment. This Agreement shall inure to and be binding
upon the parties and their respective successors and permitted assigns;
provided, however, that the Company may not assign its rights or obligations
hereunder without the express prior written consent of the Trustee, acting at
the direction of the Holders as provided in the Indenture.

                  9.5 Entire Agreement; Amendments. This Agreement and the
Indenture contain the entire agreement among the parties with respect to the
subject matter hereof and supersede any and all prior agreements, understandings
and commitments with respect thereto, whether oral or written; provided,
however, that this Agreement is executed and accepted by the Trustee and the
Escrow Agent subject to all terms and conditions of its acceptance of the trust
under the Indenture, as fully as if said terms and conditions were set forth at

authorized representatives of all parties. The Trustee and the Escrow Agent may
execute an amendment to this Agreement only if the requisite consent of the
Holders of the Notes required by Section 9.02 of the Indenture has been
obtained, unless no such consent is required by such Section 9.02 of the
Indenture.

                                                             EXHIBIT 4.06


         SECOND SUPPLEMENTAL INDENTURE, dated as of August 27, 1997 (the "Second
Supplemental Indenture"), to the Indenture, dated as of April 15, 1996, as
supplemented by the First Supplemental Indenture dated as of September 12, 1996
(the "Indenture") between HYPERION TELECOMMUNICATIONS, INC., a Delaware
corporation (the "Company"), and BANK OF MONTREAL TRUST COMPANY, a trust company
organized under the laws of the State of New York (the "Trustee").

         WHEREAS, the Company desires and has requested the Trustee to join it
in the execution and delivery of this Second Supplemental Indenture in order to
amend certain provisions of the Indenture to permit the Company's proposed
issuance of certain Senior Secured Notes due 2004 and to grant a first priority
security interest in certain of the Company's assets to the holders of such
Senior Secured Notes due 2004; and

         WHEREAS, Section 9.02 of the Indenture provides that a supplemental
indenture may be entered into by the Company and the Trustee with the consent of
at least a majority of the holders of the Senior Notes issued pursuant thereto,
provided certain conditions are met; and

         WHEREAS, at least the minimum number of the holders of the Senior Notes
required by Section 9.02 of the Indenture have consented to the proposed
amendments to the Indenture and the conditions set forth in the Indenture for
the execution and delivery of this Second Supplemental Indenture have been
complied with; and

         WHEREAS, all things necessary to make this Second Supplemental
Indenture a valid agreement of the Company and the Trustee, in accordance with
its terms, and a valid amendment of, and supplement to, the Indenture, have been
done;

         NOW THEREFORE, in consideration of the premises and the mutual
covenants herein, the Company agrees with the Trustee that the Indenture is
supplemented and amended, solely to the extent and for the purposes expressed
herein, as follows:

         Section 1.        Definitions.

                  (a) Any capitalized term used herein and not otherwise defined
         herein shall have the meaning given in the Indenture.

                  (b)      The definition of "Disqualified Stock" in Section
         1.01 of the Indenture is hereby amended and restated as follows:

         "Disqualified Stock" means any Capital Stock which, by its terms ( or
         by the terms of any security into which it is convertible or for which
         it is exchangeable), or upon the happening of any event, matures or is
         mandatorily redeemable, pursuant to a sinking fund obligation or
         otherwise, or redeemable at the option of the holder thereof, in whole
         or in part, on or prior to the date that is 91 days after the date on
         which the Senior Notes mature; provided, however, that any Capital
         Stock which would not constitute Disqualified Stock but for provisions
         thereof giving holders thereof the right to require the Company to
         repurchase or redeem such Capital Stock upon the occurrence of a Change
         of Control occurring prior to the final maturity of the Senior Notes
         shall not constitute Disqualified Stock if the change of control
         provisions applicable to such Capital Stock are no more favorable to
         the holders of such Capital Stock than the provisions applicable to the

         deemed to have breached it obligations hereunder by virtue thereof.

                  If the Purchase Date is on or after an interest record date

                  Upon the commencement of an Asset Sale Offer, the Company

         of the Asset Sale Offer, shall state:

                  (a) that the Asset Sale Offer is being made pursuant to this
         Section 3.09 and Section 4.10 hereof and the length of time the Asset

         payment shall continue to accrete or accrue interest;

                  (d) that, unless the Company defaults in making such payment,
         any Senior Note accepted for payment pursuant to the Asset Sale Offer
         shall cease to accrete or accrue interest after the Purchase Date;

                  (e) that Holders electing to have a Senior Note purchased
         pursuant to an Asset Sale Offer may only elect to have all of such
         Senior Note purchased and may not elect to have only a portion of such
         Senior Note purchased;

                  (f) that Holders electing to have a Senior Note purchased
         pursuant to any Asset Sale Offer shall be required to surrender the
         Senior Note with the form entitled "Operation of Holder to Elect
         Purchase" on the reverse of the Senior Note completed, or transfer by
         book-entry transfer, to the Company, a depositary, if appointed by the
         Company, or a Paying Agent at the address specified in the notice at
         least three days before the Purchase Date;

                  (g) that Holders shall be entitled to withdraw their election
         if the Company, the depositary or the Paying Agent, as the case may be,
         receives, not later than the expiration of the Offer Period, a
         telegram, telex, facsimile transmission or letter setting forth the
         name of the Holder, the principal amount of the Senior Note the Holder

                  (h) that, if the aggregate principal amount or Accreted Value,
         as applicable, of Senior Notes surrendered by Holders exceeds the
         amount required to be purchased pursuant to Section 4.10 hereof, the
         Company shall select the Senior Notes to be purchased on a pro rata
         basis (with such adjustments as may be deemed appropriate by the
         Company so that only Senior Notes in denominations of $1,000, or
         integral multiples thereof, shall be purchased); and

                  (i) that Holders whose Senior Notes were purchased only in
         part shall be issued new Senior Notes equal in principal amount to the
         unpurchased portion of the Senior Notes surrendered (or transferred by
         book-entry transfer).

                  On or before the Purchase Date, the Company shall, to the
         extent lawful, accept for payment, on a pro rata basis to the extent
         necessary, the Senior Notes or portions thereof tendered or required to
         be purchased pursuant to the Asset Sale Offer, or, if less than the
         amount so required to be purchased has been tendered, all Senior Notes
         tendered, and shall deliver to the Trustee an Officers' Certificate
         stating that such Senior Notes or portions thereof were accepted for
         payment by the Company in accordance with the terms of Section 4.10
         hereof and this Section 3.09. The Company, the Depository or the Paying
         Agent, as the case may be, shall promptly (but in any case not later
         than five days after the Purchase Date) mail or deliver to each
         tendering Holder an amount equal to the purchase price of the Senior
         Notes tendered by such Holder and accepted by the Company for purchase,
         and the Company shall promptly issue a new Senior Note, and the
         Trustee, upon written request from the Company shall authenticate and
         mail or deliver such new Senior Note to such Holder, in a principal
         amount equal to any unpurchased portion of the Senior Note surrendered.
         Any Senior Note not so accepted shall be promptly mailed or delivered
         by the Company to the Holder thereof. The Company shall publicly
         announce the results of the Asset Offer on the Purchase Date.

                  Other than as specifically provided in this Section 3.09, any
         purchase pursuant to this Section 3.09 shall be made pursuant to the
         provisions of Section 3.01 through 3.06 hereof.

         Debt does not exceed 80% of the purchase price or cost of the
         construction, acquisition or improvement of the applicable
         Telecommunications Related Assets;

   (iii) Refinancing Indebtedness;

   (iv)  the incurrence of Indebtedness by the Company not to exceed, at any one
         time outstanding, 2.0 times the net cash proceeds received by the
         Company from the issuance and sale of its Capital Stock (other than
         Disqualified Stock) to a Person other than a Subsidiary or a Joint
         Venture of the Company, provided that such Indebtedness (y) does not
         mature prior to the Stated Maturity of the Senior Notes and has a
         Weighted Average Life to Maturity longer than the Senior Notes and (z)
         is subordinated to the Senior Notes;

   (v)   the incurrence by the Company of Indebtedness (in addition to
         Indebtedness permitted by any other clause of this paragraph) in an
         aggregate principal amount at maturity (or accreted value, as
         applicable) at any time outstanding not to exceed $10.0 million;

   (vi)  the incurrence by any Restricted Joint Venture of Non-Recourse Debt,
         provided that if any Non-Recourse Debt of a Restricted Joint Venture
         ceases to be Non-Recourse Debt, such event shall be deemed to
         constitute an incurrence of Indebtedness as of the dates such
         Indebtedness ceases to be Non-Recourse Debt;

   (vii) the guarantee of Indebtedness by a General Partner Subsidiary in
         connection with the incurrence of Indebtedness by the Restricted Joint
         Venture of which such General Partner Subsidiary is a general partner;

   (viii)the incurrence by the Company's Subsidiaries (other than General
         Partner Subsidiaries) and Permitted Joint Ventures of Indebtedness
         (including Acquired Indebtedness) so long as all of the net proceeds of
         such incurrence are used by such Subsidiary or Permitted Joint Venture,
         as the case may be, directly in connection with the design,
         construction, development or acquisition of a Telecommunication Service
         Market; provided that, as of the last day of the Company's most
         recently ended fiscal quarter for which internal financial statements
         are available immediately preceding the date on which such Indebtedness
         is incurred, either: (a)(1) the aggregate principal amount at maturity
         of all Indebtedness outstanding of such Subsidiary or such Permitted
         Joint Venture does not exceed (x) the product of (I) 1.75 times (II)
         the total amount of Invested Equity Capital of the Subsidiary or
         Permitted Joint Venture incurring such Indebtedness minus (y) the
         product of (I) the quotient obtained by dividing (A) the total amount
         of Invested Equity Capital of the Subsidiary or Permitted Joint Venture
         incurring such Indebtedness by (B) the aggregate amount of Invested
         Equity Capital of all of the Company's Subsidiaries and Permitted Joint
         Ventures times (II) the quotient obtained by dividing (A) the aggregate
         principal amount of the then outstanding Secured Notes by (B) 1.75 and
         (2) the aggregate principal amount at maturity of all Non-Qualified
         Debt outstanding of such Subsidiary or such Permitted Joint Venture
         does not exceed (x) the product of (I) 1.50 times (II) the total amount
         of Invested Equity Capital of the Subsidiary or Permitted Joint Venture
         incurring such Non-Qualified Debt minus (y) the product of (I) the
         quotient obtained by dividing (A) the total amount of Invested Equity
         Capital of the Subsidiary or Permitted Joint Venture incurring such
         Non-Qualified Debt by (B) the aggregate amount of Invested Equity
         Capital of all of the Company's Subsidiaries and Permitted Joint
         Ventures times (II) the quotient obtained by dividing (A) the aggregate
         principal amount of the then outstanding Secured Notes by (B) 1.50; or
         (b) the Consolidated Leverage Ratio of such Subsidiary or such
         Permitted Joint Venture would not have been greater than 3.5 to 1.0;
         provided that for purposes of this clause (viii)(b) the product of (I)
         the quotient obtained by dividing (A) the total amount of Invested
         Equity Capital of the Subsidiary or Permitted Joint Venture incurring
         such Indebtedness by (B) the aggregate amount of Invested Equity
         Capital of all of the Company's Subsidiaries and Permitted Joint
         Ventures times (II) the aggregate principal amount of the then
         outstanding Secured Notes shall be added to clause (i) of the
         definition of Consolidated Leverage Ratio solely for purposes of the
         calculation thereof for purposes hereof, in each case, determined on a
         pro forma basis (including pro forma application of the net proceeds
         therefrom) as if such Indebtedness had been incurred at the beginning
         of such fiscal quarter; provided, further, any Indebtedness incurred by
         any Subsidiary of the Company or any Permitted Joint Venture (other
         than Related Networks) pursuant to this clause (viii) shall be
         non-recourse with respect to the Company or any other Subsidiary of the
         Company or any other Joint Venture;

   (ix)  the incurrence by the Company of the Existing Indebtedness; and

   (x)   the incurrence of Indebtedness by the Company with respect to the
         Secured Notes.

                  For purposes of this Section 4.09, in the event that the
         Company proposes to incur Indebtedness pursuant to clause (iv) above,
         the Company shall, simultaneously with the incurrence of such
         Indebtedness, deliver to the Trustee a resolution of the Board of
         Directors set forth in an Officers' Certificate stating that the sale
         or sales of Capital Stock forming the basis for the incurrence of such
         Indebtedness (i) constitutes a long term investment in the Company and
         (ii) has not been made for the purpose of circumventing this Section
         4.09. In the event that the Company rescinds, reverses or unwinds such
         sale of Capital Stock or otherwise returns or refunds all or any
         portion of the net cash proceeds of such sale of Capital Stock (whether
         by dividend, distribution or otherwise) within 270 days of the date of
         the incurrence of such Indebtedness, such Indebtedness will be deemed
         to be incurred on the date of, and immediately after giving effect to,
         such rescission, reversal, unwinding, return or refund.

                  For purposes of this Section 4.09, in the event that a
         Restricted Joint Venture becomes a Permitted Joint Venture or otherwise
         ceases to be a Restricted Joint Venture, all of the then outstanding
         Indebtedness of such entity shall be deemed to have been incurred as of
         the date that such Restricted Joint Venture becomes a Permitted Joint
         Venture or otherwise ceases to be a Restricted Joint Venture.



     Section 5.   Asset Sales.  Section 4.10 of the Indenture shall be amended
         and restated as follows:

                  The Company shall not, and shall not permit any Subsidiary to,
         directly or indirectly, whether in a single transaction or a series of
         related transactions occurring within any twelve-month period, make any
         Asset Sale, unless

    (i)  the Company or the Subsidiary, as the case may be, receives
         consideration at the time of such Asset Sale at least equal to the fair
         market value (as determined in good faith by the Board of Directors)
         for the shares or assets sold or otherwise disposed of; and

    (ii) at least 90% of such consideration consists of cash,

         provided that

  (A)    an amount equal to the fair market value (as determined in good faith
         by the Board of Directors) of:

    (1)  Telecommunications Related Assets received by the Company or any
         Subsidiary from the transferee that will be used by the Company or such
         Subsidiary in the operation of a Telecommunications Business;

    (2)  the Voting Stock of any Person engaged in a Telecommunications Business
         received by the Company or any Subsidiary; provided that on the date
         such Voting Stock is received, such Investment in Voting Stock
         constitutes a Permitted Joint Venture Investment; or

         (3) the publicly tradable Voting Stock of any person engaged in the
         Telecommunications Business received by the Company or any Subsidiary
         as consideration for a sale of an Equity Interest in any Restricted
         Joint Venture, shall, for the purposes of this Section 4.10, be deemed
         to be cash which was applied in accordance with the first sentence of
         the penultimate paragraph of this Section 4.10; and

     (B) in the event that any of Hyperion Telecommunications of Pennsylvania,
         Inc., Hyperion Telecommunications of Tennessee, Inc. or Hyperion
         Telecommunications of New York, Inc. sell their respective partnership
         interests in the partnerships to which each is a partner to the
         respective partnerships in the manner specified by the applicable
         partnership agreement, (1) the principal amount at maturity of any
         seller note issued to the Company or any of its Wholly Owned
         Subsidiaries shall be deemed to be cash for purposes of this Section
         4.10 and (2) the payments of principal pursuant to such seller note
         shall be deemed to be Net Cash Proceeds (for purposes of the
         penultimate paragraph of this Section 4.10) as and when such payments
         are received.

                  For purposes of this Section 4.10, the first $1.0 million of
         Net Cash Proceeds received from Asset Sales (other than Asset Sales of
         Stock Collateral) in any fiscal year shall not be subject to the
         restrictions contained in this section.

                  In determining the fair market value with respect to any Asset
         Sale or series of related Asset Sales involving aggregate consideration
         in excess of $10.0 million, the Board of Directors of the Company must
         obtain an opinion as to the fairness to the Holders of Senior Notes of
         such Asset Sales from a financial point of view issued by a nationally
         recognized investment banking firm with total assets in excess of $1.0
         billion; provided that no such opinion shall be required if such Asset
         Sale is in accordance with the terms of any Local Partnership Agreement
         to which the Company or any of its Subsidiaries is a party on the date
         hereof.

                  The Company may apply the Net Cash Proceeds from any Asset
         Sale to an investment in Telecommunications Related Assets in a
         Telecommunications Service Market within 180 days after such Asset
         Sale; provided that if the Company determines to make such investment
         in a New Telecommunications Service Market, the Company shall be deemed
         to have complied with the first clause of this sentence if, the Company
         (y) within 180 days of such Asset Sale, delivers to the Trustee a
         resolution adopted by a majority of the Board of Directors set forth in
         an Officer's Certificate certifying that the Company intends to utilize
         the Net Cash Proceeds of such Asset Sale to invest in a specific new
         Telecommunications Service Market and (z) completes such investment
         within 360 days of such Asset Sale. The Company shall be deemed to have
         completed its investment for purposes of the preceding clause (z), so
         long as the Company has (i) a business plan that sets forth the
         Company's investment plans for the applicable Telecommunications
         Service Market and (ii) issued all material purchase orders to the
         appropriate parties that are necessary to complete such business plan.
         Any Net Cash Proceeds from an Asset Sale that are not invested as
         provided in the two preceding sentences shall constitute Excess
         Proceeds. When the aggregate amount of Excess Proceeds exceeds $2.5
         million, the Company shall commence to purchase (an "Asset Sale Offer")
         the maximum principal amount of Senior Notes and Senior Secured Notes
         (on a pro rata basis based upon the relative aggregate principal amount
         of Senior Notes (or, prior to April 15, 2001, the aggregate Accreted
         Value of Senior Notes) and Secured Notes then outstanding) that may be
         purchased out of the Excess Proceeds, at an offer price in cash equal
         to 100% of aggregate principal amount thereof, plus accrued and unpaid
         interest to the date of repurchase (or, in the case of repurchases of
         Senior Notes prior to April 15, 2001, at a purchase price equal to 100%
         of the Accreted Value thereof as of the date of repurchase) in
         accordance with the procedures set forth in this Indenture, provided,
         that, in the event of an Asset Sale Offer as a result (in whole or in
         part) of an Asset Sale of Stock Collateral, the Company shall, purchase
         (i) first, all Secured Notes tendered pursuant to such Asset Sale Offer
         in an aggregate principal amount equal to the portion of such Excess
         Proceeds resulting from such Asset Sale of Stock Collateral and (ii)
         second, all Secured Notes and Senior Notes on a pro rata basis (in the
         same manner as described above) in an aggregate principal amount (or,
         with respect to Senior Notes prior to April 15, 2001, an aggregate
         Accreted Value) equal to the Excess Proceeds not used to purchase
         Secured Notes pursuant to clause (i) of this proviso. To the extent
         that the aggregate principal amount at maturity thereof, plus accrued
         and unpaid interest to the date of repurchase (or, in the case of
         repurchases of Senior Notes prior to April 15, 2001, the Accreted Value
         thereof as of the date of repurchase) of the Senior Notes and the
         Secured Notes tendered pursuant to an Asset Sale Offer is less than the
         Excess Proceeds, the Company may use such remaining Excess Proceeds for
         any purpose not prohibited by this Indenture. If the aggregate
         principal amount at maturity thereof, plus accrued and unpaid interest
         to the date of repurchase (or, in the case of repurchases of Senior
         Notes prior to April 15, 2001, the Accreted Value thereof as of the
         date of repurchase) of Senior Notes and of Secured Notes surrendered by
         their respective holders exceeds the amount of Excess Proceeds, the
         Trustee shall select the Senior Notes and Secured Notes to be purchased
         on a pro rata basis. Upon completion of such offers, the amount of
         Excess Proceeds shall be reset at zero. Pending application of the Net
         Cash Proceeds as set forth above from Asset Sales, all such Net Cash
         Proceeds shall be placed in escrow for the benefit of the Holders of
         Senior Notes and Secured Notes.

                  Notwithstanding the foregoing, the Company shall not, and
         shall not permit any Subsidiary to, directly or indirectly, make any
         Asset Sale of any Equity Interests of any Subsidiary (at least 80% of
         the voting power of the Capital Stock of which is owned by the Company)
         except pursuant to an Asset Sale of all of the Equity Interests of such
         Subsidiary; provided that any sale of any Equity Interest of any such
         Subsidiary to a Strategic Investor shall be deemed not be an Asset Sale
         for purposes of this Section 4.10, so long as such sale of such Equity
         Interests does not result in such Subsidiary ceasing to be a Subsidiary
         of the Company.


         Section 6. Confirmation of Indenture. Except as supplemented by this
Second Supplemental Indenture, the Indenture is hereby ratified and confirmed in
all respects and made applicable in all respects to the Senior Notes and the
holders thereof. The Indenture and this Second Supplemental Indenture shall be
read and construed as one and the same instrument.

         IN WITNESS WHEREOF, the parties hereto have caused this Second
Supplemental Indenture to be duly executed, and attested, all as of the date and
first year above written.

The Series A Notes will be issued pursuant to an indenture (the "Indenture"), to

         ACT"), AND THE SECURITY EVIDENCED HEREBY MAY NOT BE OFFERED, SOLD OR
         OTHERWISE TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR AN

         REPRESENTATIONS AND AGREEMENTS RELATING TO THE TRANSFER OF THIS NOTE OR
         (e) IN ACCORDANCE WITH ANOTHER EXEMPTION FROM THE REGISTRATION
         REQUIREMENTS OF THE SECURITIES ACT (AND BASED UPON AN OPINION OF

         IT WILL NOTIFY ANY PURCHASER OF THE SECURITY EVIDENCED HEREBY, PRIOR TO
         CLOSING OF ANY SALE, OF THE RESALE RESTRICTIONS SET FORTH IN (Y)
         ABOVE."

         2. Offering. The Series A Notes will be offered and sold to the Initial
Purchasers pursuant to an exemption from the registration requirements under the
Act. The Company has prepared a preliminary Offering Memorandum, dated August
13, 1997 (the "Preliminary Offering Memorandum") and a final offering
memorandum, dated August 21, 1997 (the "Offering Memorandum"), relating to the
Series A Notes.

         The Initial Purchasers have advised the Company that the Initial
Purchasers will make offers (the "Exempt Resales") of the Series A Notes on the
terms set forth in the Offering Memorandum, as amended or supplemented, solely
to (i) persons whom the Initial Purchasers reasonably believe to be "qualified
institutional buyers," as defined in Rule 144A under the Act ("QIBs") and (ii)
to non-U.S. persons outside

the United States in reliance upon Regulation S under the Securities Act. The
persons specified in clauses (i) and (ii) above are referred to herein as the
"Eligible Purchasers." The Initial Purchasers will offer the Series A Notes to
such Eligible Purchasers initially at the price set forth herein. Such price may
be changed at any time without notice.

         Holders (including subsequent transferees) of the Series A Notes will
have the registration rights set forth in the registration rights agreement
relating thereto (the "Registration Rights Agreement") to be dated the Closing
Date, in substantially the form of Exhibit A hereto for so long as such Series A

agreement). Pursuant to the Registration Rights Agreement, the Company will
agree to file with the Securities and Exchange Commission (the "Commission"),
under the circumstances set forth therein, (i) a registration statement under
the Act (the "Exchange Offer Registration Statement") relating to the Company's
12 1/4% Series B Senior Secured Notes due 2004 (the "Series B Notes") to be
offered in exchange for the Series A Notes (the "Exchange Offer") and (ii) a
shelf registration statement pursuant to Rule 415 under the Act (the "Shelf
Registration Statement") relating to the resale by certain holders of the Series
A Notes, and to use its best efforts to cause such registration statements to be
declared effective and consummate the Exchange Offer.

         This Agreement, the Indenture, the Senior Notes, the Escrow and
Disbursement Agreement, the Pledge Agreement and the Registration Rights
Agreement are hereinafter sometimes referred to collectively as the "Operative
Documents."

         3. Purchase, Sale and Delivery. (a) On the basis of the
representations, warranties and covenants contained in this Agreement, and
subject to its terms and conditions, the Company agrees to issue and sell to the
Initial Purchasers, and each Initial Purchaser agrees severally and not jointly
to purchase from the Company, the aggregate principal amount of Series A Notes
set forth opposite its name on Schedule I hereto. The purchase price to be paid
by the Initial Purchasers for the Series A Notes shall be 97.50% of the
aggregate principal amount thereof.

         (b) Delivery of the Series A Notes shall be made, against payment of
the purchase price therefor, at the offices of Latham & Watkins at 885 Third

Such delivery and payment shall be made at 10:00 a.m., New York time, on August

Initial Purchasers and the Company. The time and date of such delivery and
payment are herein called the "Closing Date."

         (c) One or more Series A Notes in definitive form, registered in the
name of Cede & Co., as nominee of The Depository Trust Company ("DTC"), having
an aggregate amount corresponding to the aggregate amount of the Series A Notes
(the "Global Note"), shall be delivered by the Company to the Initial Purchasers
(or as the Initial Purchasers direct), against payment by the Initial Purchasers
of the purchase price therefor, by wire transfer of immediately available funds
to the Company's account, provided that the Company shall give at least two
business days' prior written notice to the Initial Purchasers of the information
required to effect such wire transfers. The Global Note shall be made available
to the Initial Purchasers for inspection not later than 9:30 a.m. on the

<PAGE>




                  (a) To advise the Initial Purchasers promptly and, if
         requested by the Initial Purchasers, confirm such advice in writing of,
         (i) the issuance by any state securities commission of any stop order
         suspending the qualification or exemption from qualification of any
         Series A Notes for offering or sale in any jurisdiction, or the
         initiation of any proceeding for such purpose by any state securities
         commission or other regulatory authority; and (ii) the happening of any
         event that, in the reasonable opinion of either counsel to the Company
         or counsel to the Initial Purchasers, makes any statement of a material
         fact made in the Preliminary Offering Memorandum or the Offering
         Memorandum untrue or that requires the making of any additions to or
         changes in the Preliminary Offering Memorandum or the Offering
         Memorandum in order to make the statements therein, in the light of the
         circumstances under which they are made, not misleading. The Company
         shall use its best efforts to prevent the issuance of any stop order or
         order suspending the qualification or exemp-

         tion of any Series A Notes under any state securities or Blue Sky laws
         and, if at any time any state securities commission or other regulatory
         authority shall issue an order suspending the qualification or
         exemption of any Series A Notes under any state securities or Blue Sky
         laws, the Company shall use its best efforts to obtain the withdrawal
         or lifting of such order at the earliest possible time.

                  (b) To furnish the Initial Purchasers and those persons
         identified by the Initial Purchasers to the Company, without charge, as
         many copies of the Preliminary Offering Memorandum and the Offering
         Memorandum, and any amendments or supplements thereto, as the Initial
         Purchasers may reasonably request. The Company consents to the use of
         the Preliminary Offering Memorandum and the Offering Memorandum, and
         any amendments and supplements thereto required pursuant hereto, by the
         Initial Purchasers in connection with Exempt Resales.

                  (c) Not to amend or supplement the Preliminary Offering
         Memorandum or the Offering Memorandum prior to the Closing Date unless
         the Initial Purchasers shall previously have been advised thereof and
         shall not have objected thereto within a reasonable time after being
         furnished a copy thereof. The Company shall promptly prepare, upon the
         Initial Purchasers' request, any amendment or supplement to the
         Preliminary Offering Memorandum or the Offering Memorandum that may be
         necessary or reasonably requested by the Initial Purchasers in
         connection with Exempt Resales.

                  (d) If, after the date hereof and prior to consummation of any
         Exempt Resale, any event shall occur as a result of which, in the
         judgment of the Company or in the reasonable opinion of either counsel
         to the Company or counsel to the Initial Purchasers, it becomes
         necessary or advisable to amend or supplement the Preliminary Offering
         Memorandum or Offering Memorandum in order to make the statements
         therein, in the light of the circumstances when such Offering
         Memorandum is delivered to an Eligible Purchaser which is a prospective
         purchaser, not misleading, or if it is necessary or advisable to amend
         or supplement the Preliminary Offering Memorandum or Offering
         Memorandum to comply with applicable law, (i) notify the Initial
         Purchasers and (ii) forthwith to prepare an appropriate amendment or
         supplement to such Offering Memorandum so that the statements therein
         as so amended or supplemented will not, in the light of the
         circumstances when it is so delivered, be misleading, or so that such
         Offering Memorandum will comply with applicable law.

                  (e) To cooperate with the Initial Purchasers and counsel to
         the Initial Purchasers in connection with the qualification or
         registration of the Series A Notes under the securities or Blue

         request and to continue such qualification in effect so long as
         required for the Exempt Resales; provided that the Company shall not be
         required to take any action that would subject it to service of process

         relating to the Preliminary Offering Memorandum, the Offering
         Memorandum or Exempt Resales, in any jurisdiction where it is not now
         so subject.

                  (f) Whether or not the transactions contemplated by this
         Agreement are consummated or this Agreement becomes effective or is

         performance of the obligations of the Company hereunder, including in

         the Initial Purchasers, (iv) the qualification or registration of the

         of the several states (including, without limitation, the cost of
         printing and mailing a preliminary and final Blue Sky Memorandum and
         the reasonable fees and disbursements of counsel to the Initial
         Purchasers relating to such qualification or registration), (v)

         otherwise negotiate in respect of any security (as defined in the Act)
         that would be integrated with the sale of the Series A Notes in a

         Eligible Purchasers of the Series A Notes or to take any other action
         that would result in the Exempt Resales not being exempt from
         registration under the Act.

                  (k) For so long as any of the Senior Notes remain outstanding
         and during any period in which the Company is not subject to Section 13
         or 15(d) of the Securities Exchange Act of 1934, as amended (the
         "Exchange Act"), to make available to any Eligible Purchaser or
         beneficial owner of Series A Notes in connection with any sale thereof
         and any prospective purchaser of such Series A Notes from such Eligible

                  5.       Representations and Warranties.

                  (a) The Company represents and warrants to each of the Initial
         Purchasers that:

                  (i) The Preliminary Offering Memorandum and the Offering
         Memorandum (and each supplement and amendment thereto) have been
         prepared in connection with the Exempt Resales. The Preliminary
         Offering Memorandum and the Offering Memorandum do not, and any
         supplement or amendment to them will not, contain any untrue statement
         of a material fact or omit to state any material fact necessary in
         order to make the statements therein, in the light of the circumstances
         under which they were made, not misleading, except that the
         representations and warranties contained in this paragraph shall not
         apply to statements in or omissions from the Preliminary Offering
         Memorandum and the Offering Memorandum (or any supplement or amendment
         thereto) made in reliance upon and in conformity with information
         relating to the Initial Purchasers furnished to the Company in writing
         by or on behalf of the Initial Purchaser expressly for use therein. No
         stop order preventing the use of the Preliminary Offering Memorandum or
         the Offering Memorandum, or any amendment or supplement thereto, or any
         order asserting that any of the transactions contemplated by this
         Agreement are subject to the registration requirements of the Act, has
         been issued.

                  (ii) When the Series A Notes are issued and delivered pursuant
         to this Agreement, no Senior Note will be of the same class (within the
         meaning of Rule 144A under the Act) as securities of the Company that
         are listed on a national securities exchange registered under Section 6
         of the Exchange Act or that are quoted in a United States automated
         inter-dealer quotation system.

                  (iii) Each of the Company and its Subsidiaries (as defined)
         (A) has been duly organized, is validly existing as a corporation in
         good standing under the laws of its respective jurisdiction of
         incorporation, (B) has all requisite corporate power and authority to
         carry on its business as it is currently being conducted and as
         described in the Offering Memorandum and to own, lease and operate its
         properties and (C) is duly qualified and in good standing as a foreign
         corporation 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



<PAGE>



         or adversely affect the issuance or marketability of the Series A Notes
         or (z) in any manner draw into question the validity of this Agreement
         or any other Operative Document or the ability to conduct its business
         in the manner set forth in the Offering Memorandum (any of the events
         set forth in clauses (x), (y) or (z), a "Material Adverse Effect"). The
         Company has no direct or indirect subsidiaries as of the Closing Date
         other than those set forth on Schedule II hereto (referred to herein
         collectively as "Subsidiaries" and individually as a "Subsidiary").

                  (iv) Each of the Joint Ventures (as defined) (A) has been duly
         formed as a partnership or corporation, as applicable, under the laws
         of its respective jurisdiction of formation, (B) has all requisite
         partnership or corporate power and authority, as applicable, to carry
         on its business as it is currently being conducted and as described in
         the Offering Memorandum and to own, lease and operate its properties
         and (C) is duly qualified and in good standing as a foreign partnership
         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 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 III hereto
         (referred to herein collectively as "Joint Ventures" and individually a
         "Joint Venture").

                  (v) All of the outstanding shares of capital stock of the
         Company have been duly authorized and validly issued and are fully paid
         and nonassessable and were not issued in violation of any preemptive or
         similar rights. At June 30, 1997, on a combined basis, after giving
         effect to the issuance and sale of the Series A Notes pursuant hereto,
         the Company had an authorized and outstanding consolidated
         capitalization as set forth in the Offering Memorandum under the
         caption "Capitalization."

                  (vi) 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 other charge or
         encumbrance. Except as disclosed in the Offering Memorandum, there are
         not currently, and will not be as a result of the Offering, 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.

                  (vii) The Company has all requisite corporate power and
         authority to execute, deliver and perform its obligations under this
         Agreement, the Indenture, the Escrow and Disbursement Agreement, the
         Pledge Agreement, the Registration Rights Agreement and any other
         Operative Documents and to consummate the transactions contemplated
         hereby and thereby, including, without limitation, the corporate power
         and authority to issue, sell and deliver the Series A Notes as provided
         herein and therein.

                  (viii) This Agreement has been duly and validly authorized,
         executed and delivered by 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.

         Company and, when duly executed and delivered by the Company, will be
         the legal, valid and binding obligation of the Company, enforceable
         against the Company in accordance with its terms, subject to applicable

         to this Agreement and, when issued and authenticated in accordance with
         the terms of the Indenture and delivered against payment therefor in
         accordance with the terms hereof and thereof, will be the legal, valid
         and binding obligations of the Company, enforceable against the Company
         in accordance with their terms and entitled to the benefits of the
         Indenture, subject to applicable bankruptcy, insolvency, fraudulent
         conveyance, reorganization or similar laws affecting the rights of
         creditors generally and subject to general principles of equity. The
         description of the Series A Notes in the Offering Memorandum is
         accurate in all material respects.

                  (xi) The Series B Notes have been duly and validly authorized
         for issuance by the Company and, when issued and authenticated in
         accordance with the terms of the Exchange Offer and the Indenture, will
         be the legal, valid and binding obligations of the Company, enforceable
         against the Company in accordance with their terms and entitled to the
         benefits of the Indenture, subject to applicable bankruptcy,

         affecting the rights of creditors generally and subject to general
         principles of equity. The description of the Series B Notes in the
         Offering Memorandum is accurate in all material respects.

                  (xii) The Registration Rights Agreement has been duly and
         validly authorized by the Company and, when duly executed and delivered
         by the Company, will be the legal, valid and binding obligation of the

         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

         violations conflicts, breaches, defaults, consents, impositions of
         liens or accelerations that would not singly, or in the aggregate, have
         a Material Adverse Effect. Other than as described in the Offering
         Memorandum, 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 and the other Operative Documents or (2) the issuance and
         sale of the Senior Notes and the transactions contemplated hereby and
         thereby, except (x) such as have been obtained and made (or, in the
         case of the Registration Rights Agreement, will be obtained and made)

         Indenture 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

         any court, arbitrator or governmental agency, body or official,

         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

         agency or, to the best of the Company's knowledge, that has been
         proposed by any governmental body or (iii) no injunction, restraining
         order or order of any nature by a federal or state court or foreign
         court of competent jurisdiction to which the Company, any Subsidiary or
         any Joint Venture is or could reasonably be expected to be subject or
         to which the business, assets, or property of the Company, any
         Subsidiary or any Joint Venture are could reasonably be expected to be
         subject, that, in the case of clauses (i), (ii) and (iii) above, (y) is
         required to be disclosed in the Preliminary Offering Memorandum and the
         Offering Memorandum and that is not so disclosed, or (z) could
         reasonably be expected to individually or in the aggregate, result in a
         Material Adverse Effect.

                  (xviii) No action has been taken and no local, state or
         Federal law, statute, ordinance, rule, regulation, requirement,
         judgment or court decree has been enacted, adopted or issued by any
         governmental agency that prevents the issuance of the Senior Notes or
         prevents or suspends the use of the Offering Memorandum; no injunction,
         restraining order or order of any nature by a federal or state court of

         request of any securities authority or agency of any jurisdiction for
         additional information has been complied with in all material respects.

                  (xix) There is (i) no unfair labor practice complaint pending
         against the Company, any Subsidiary 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

         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

         above could reasonably be expected to result in a Material Adverse
         Effect.

                  (xx) 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.

                  (xxi) 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 Offering Memorandum as owned by it, free and
         clear of all liens, charges, encumbrances and restrictions, except such
         as are described in the Offering Memorandum 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 (each an "Authorization") necessary to engage in
         the business as presently conducted by any of them in the manner
         described in the Offering Memorandum, except as described in the
         Offering Memorandum 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.

         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.

         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 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.

                  (xxiv) 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.

         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 (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 "PUC Act").

                  (xxvi) There are no holders of securities of the Company, the
         Subsidiaries or the Joint Ventures who, by reason of the execution by
         the Company of this Agreement or any other Operative Document to which
         it is a party or the consummation by the Company of the transactions
         contemplated hereby and thereby, 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 under the Act.

                  (xxvii) 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.

         Ventures maintains insurance



<PAGE>



         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.

                  (xxix) None of the Company, any Subsidiary or any Joint
         Venture has (i) taken, directly or indirectly, any action designed to,

         Company to facilitate the sale or resale of the Series A Notes (ii)
         since the date of the Preliminary Offering Memorandum (A) sold, bid

         purchases of the Senior Notes or (B) paid or agreed to pay to any
         person any compensation for soliciting another to purchase any other
         securities of the Company.

                  (xxx) No registration under the Act of the Series A Notes is
         required for the sale of the Series A Notes to the Initial Purchasers
         as contemplated hereby or for the Exempt Resales assuming (i) that the
         purchasers who buy the Series A Notes in the Exempt Resales are
         Eligible Purchasers and (ii) the accuracy of the Initial Purchasers'
         representations regarding the absence of general solicitation in
         connection with the sale of Series A Notes to the Initial Purchasers
         and the Exempt Resales contained herein. No form of general
         solicitation or general advertising was used by the Company or any of
         its representatives (other than the Initial Purchasers, as to which the
         Company makes no representation or warranty) in connection with the
         offer and sale of the Series A Notes in connection with Exempt Resales,
         including, but not limited to, articles, notices or other
         communications published in any newspaper, magazine, or similar medium
         or broadcast over television or radio, or any seminar or meeting whose
         attendees have been invited by any general solicitation or general
         advertising. No securities of the same class as the Series A Notes have
         been issued and sold by the Company within the six-month period
         immediately prior to the date hereof.

                  (xxxi) Set forth on Exhibit C 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, the other Operative Documents and the sale of the Series A
         Notes to be purchased by the QIBs 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. The representation
         made by the Company in the preceding sentence is made in reliance upon
         and subject to the accuracy of, and compliance with, the
         representations and covenants made or deemed made by the QIBs as set
         forth in the Offering Memorandum under the caption "Notice to
         Investors."

                  (xxxii) Each of the Preliminary Offering Memorandum and the
         Offering Memorandum, as of its date, and each amendment or supplement
         thereto, as of its date, contains the information specified in, and
         meets the requirements of, Rule 144A(d)(4) under the Act.

         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.

         Memorandum, 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.

                  (xxxv) The accountants who have certified or will certify the
         financial statements included or to be included as part of the Offering
         Memorandum are independent accountants. 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-4 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 periods
         presented. The other financial information and data included in the
         Offering Memorandum, historical and pro forma, are accurately presented
         in all material respects and prepared on a basis consistent with the
         financial statements, historical and pro forma, included in the
         Offering Memorandum and the books and records of the Company, each of
         its Subsidiaries and each of its Joint Ventures, as applicable. The
         statistical information and data included in the Offering Memorandum
         are accurately presented in all material respects.

                  (xxxvi) On and after the Closing Date, the Company is and will
         be the sole beneficial owner of the Pledged Securities and no Lien will
         exist upon any such Pledged Securities (and no right or option to
         acquire the same will exist in favor of any other person or entity),
         except for the pledge and security interest in favor of the Trustee to
         be created or provided for in the Escrow and Disbursement Agreement,
         which pledge and security interest constitute a first priority
         perfected pledge and security interest in and to all of the Pledged
         Securities.

                  (xxxvii) Subject to the terms and conditions of this
         Agreement, the execution by the Company of the Pledge Agreement and
         delivery to the Trustee of the Stock Collateral pursuant thereto, shall
         cause the Trustee, for the ratable benefit of the holders of the Senior
         Notes, to have, as security for the payment of the obligations under
         the Indenture and the Senior Notes, a valid, duly perfected security
         interest (as to the creation of which no consent is required by a third
         party or such consents have been obtained, except as set forth in the
         Offering Memorandum, solely with respect to the Additional Collateral
         (as such term is defined in the Pledge Agreement)) in the Stock



<PAGE>



         Collateral and the actions described in this section (xxxvii) are the
         only actions, recordings and filings necessary to establish the
         validity of such security interest in the Stock Collateral (except as
         set forth in the Offering Memorandum, solely with respect to the
         Additional Collateral and as required by the Pledge Agreement). From
         and after the date hereof (except as set forth in the Offering
         Memorandum, solely with respect to the Additional Collateral and as
         required by the Pledge Agreement) the liens or security interests
         created by the Stock Collateral will be duly perfected, creating a
         first priority interest in the Trustee for the ratable benefit of the
         holders of the Senior Notes in the Stock Collateral over all other
         liens and security interests in respect of the Stock Collateral,
         whether now existing or hereafter created.

                  (xxxviii) Each of the Pledge Agreement and the Escrow and
         Disbursement Agreement will secure the obligations of the Company under
         the Senior Notes and the Indenture.

                  (xxxix) The Company does not intend to, nor does it believe
         that it will, incur debts beyond its ability to pay such debts as they
         mature. The present fair saleable value of the assets of the Company on
         a consolidated basis exceeds the amount that will be required to be
         paid on or in respect of the existing debts and other liabilities
         (including contingent liabilities) of the Company on a consolidated
         basis as they become absolute and matured. The assets of the Company on
         a consolidated basis do not constitute unreasonably small capital to
         carry out the business of the Company, the Subsidiaries and the Joint
         Ventures, taken as a whole, as conducted or as proposed to be
         conducted. Upon the issuance of the Series A Notes, the present fair
         saleable value of the assets of the Company on a consolidated basis
         will exceed the amount that will be required to be paid on or in
         respect of the existing debts and other liabilities (including
         contingent liabilities) of the Company on a consolidated basis as they
         become absolute and matured. Upon the issuance of the Series A Notes,
         the assets of the Company on a consolidated basis will not constitute
         unreasonably small capital to carry out its businesses as now
         conducted, including the capital needs of the Company on a consolidated
         basis, taking into account the projected capital requirements and
         capital availability.

                  (xl) 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
         Initial Purchasers for a brokerage commission, finder's fee or like
         payment in connection with the issuance, purchase and sale of the
         Series A Notes.

                  (xli) 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.

                  (xlii) Except as disclosed in the Offering Memorandum, 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 (assuming for purposes of this paragraph 5(xlii) only that
         Regulation S-K is applicable to the Offering Memorandum).

                  (xliii) None of the Company, the Subsidiaries, the Joint
         Ventures nor any of their respective affiliates or any person acting on
         their behalf has engaged or will engage in any directed



<PAGE>



         selling efforts within the meaning of Regulation S with respect to the
         Series A Notes, and each of the Company, the Subsidiaries, the Joint
         Ventures and their respective affiliates and all persons acting on its
         or their behalf have complied with and will comply with the offering
         restrictions of Regulation S in connection with the offering of the
         Series A Notes outside the United States.

                  (xliv) The Series A Notes offered an sold in reliance on
         Regulation S have been and will be offered and sold only in offshore
         transactions and such securities have been and will be represented upon
         issuance by a global security that may not be exchanged for definitive
         securities until the expiration of the restricted period (as defined in
         Regulation S) and only upon certification of beneficial ownership of
         the securities by a non-U.S. person or a U.S. person who purchased such
         securities in a transaction that was exempt from the registration
         requirements of the Act, which U.S. person will acquire an interest in
         a Transfer Restricted Security (as defined in the Registration Rights
         Agreement).

                  (xlv) The sale of the Series A Notes pursuant to Regulation S
         is not part of a plan or scheme to evade the registration provisions of
         the Act.

                  Each certificate signed by any officer of the Company and
delivered to the Initial Purchasers or counsel for the Initial Purchasers
pursuant to this Agreement shall be deemed to be a representation and warranty
by the Company to the Initial Purchasers as to the matters covered thereby.

                  The Company acknowledges that each of the Initial Purchasers
and, for purposes of the opinions to be delivered to the Initial Purchasers
pursuant to Section 8 hereof, counsel to the Company and counsel to the Initial
Purchasers, will rely upon the accuracy and truth of the foregoing
representations and hereby consents to such reliance.

         (b) Each of the Initial Purchasers severally and not jointly
represents, warrants and covenants to the Company and agrees that:

                  (i) Such Initial Purchaser is a QIB, with such knowledge and
         experience in financial and business matters as are necessary in order
         to evaluate the merits and risks of an investment in the Series A
         Notes.

                  (ii) Such Initial Purchaser (A) is not acquiring the Series A
         Notes with a view to any distribution thereof that would violate the
         Act or the securities laws of any state of the United States or any
         other applicable jurisdiction and (B) will be reoffering and reselling
         the Series A Notes only to QIBs in reliance on the exemption from the
         registration requirements of the Act provided by Rule 144A and to
         non-U.S. persons outside the United States in offshore transactions in
         reliance upon Regulation S under the Act.

                  (iii) No form of general solicitation or general advertising
         has been or will be used by any of the Initial Purchasers or any of
         their representatives in connection with the offer and sale of any of
         the Series A Notes, including, but not limited to, articles, notices or
         other communications published in any newspaper, magazine, or similar
         medium or broadcast over television or radio, or any seminar or meeting
         whose attendees have been invited by any general solicitation or
         general advertising.

                  (iv) In connection with the Exempt Resales, such Initial
         Purchaser will solicit offers to buy the Series A Notes only from, and
         will offer to sell the Series A Notes only to, Eligible Purchasers.
         Such Initial Purchaser further agrees (A) that it will offer to sell
         the Series A Notes only to, and will solicit offers to buy the Series A
         Notes only from (1) QIBs who in purchasing such Series A Notes will be
         deemed to have represented and agreed that they are purchasing the
         Series A Notes for their own accounts or accounts with respect to which
         they exercise sole investment discretion and that they or such accounts
         are QIBs and (B) that such QIBs acknowledge and agree that such Series
         A Notes will not have been registered under the Act and may be resold,
         pledged or otherwise transferred only (x)(I) to a person who the seller
         reasonably believes is a QIB in a transaction meeting the requirements
         of Rule 144A or (II) in a transaction meeting the requirements of Rule
         144 or (III) outside the United States in a transaction meeting the
         requirements of Rule 903 or 904 of Regulation S under the Securities
         Act, (IV) to an institutional "accredited investor" (as defined in Rule
         501(a)(1), (2), (3) or (7) of Regulation D under the Securities Act
         that prior to such transfer, furnishes to the Trustee a signed letter
         containing certain representations and agreements relating to the
         transfer of the Notes or (V) in accordance with another exemption from
         the registration requirements of the Act (and based upon an opinion of
         counsel if the Company so requests), (y) to the Company or (z) pursuant
         to an effective registration statement under the Act and, in each case,
         in accordance with any applicable securities laws of any state of the
         United States or any other applicable jurisdiction and (C) that the
         holder will, and each subsequent holder is required to, notify any
         purchaser of the security evidenced thereby of the resale restrictions
         set forth in (B) above.

                  (v) Such Initial Purchaser agrees that it has offered the
         Series A Notes and will offer and sell the Series A Notes (i) as part
         of its distribution at any time and (ii) otherwise until 40 days after
         the later of the commencement of the offering of the Series A Notes and
         the Closing Date, only in accordance with Rule 903 of Regulation S or
         another exemption from the registration requirements of the Act.
         Accordingly, neither such Initial Purchaser, its affiliates nor any
         persons acting on its or their behalf has engaged or will engage in any
         directed selling efforts within the meaning of Rule 901(b) of
         Regulation S with respect to the Series A Notes, and such Initial
         Purchaser, its affiliates and all persons acting on its or their behalf
         have complied and will comply with the offering restrictions
         requirements of Regulation S.

                  (vi) Such Initial Purchaser agrees that the Series A Notes
         offered and sold in reliance on Regulation S have been and will be
         offered and sold only in offshore transactions and that such securities
         have been and will be represented upon issuance by a global security
         that may not be exchanged for definitive securities until the
         expiration of the restricted period (as defined in Regulation S) and
         only upon certification of beneficial ownership of the securities by a
         non-U.S. person or a U.S. person who purchased such securities in a
         transaction that was exempt from the registration requirements of the
         Act, which U.S. person will acquire an interest in a Registrable
         Security (as defined in the Registration Rights Agreement).

                  (vii) Such Initial Purchaser agrees that, at or prior to
         confirmation of a sale of Series A Notes, it will have sent to each
         distributor, dealer or person receiving a selling concession, fee or
         other remuneration that purchases Series A Notes from it during the
         restricted period (as defined in Regulation S) a confirmation or notice
         to substantially the following effect:

         A The Securities covered hereby have not been registered under the U.S.

<PAGE>



         amended (the ASecurities Act@), and may not be offered and sold within
         the United States or to, or for the account or benefit of, U.S. persons
         (i) as part of their distribution at any time or (ii) otherwise until
         40 days after the later of the commencement of the Offering and the
         Closing Date, except in either case in accordance with Regulation S (or
         Rule 144A or in transactions that are exempt from the registration
         requirements of the Securities Act) under the Securities Act. Terms
         used above have the meanings assigned to them in Regulation S.@

         Such Initial Purchaser further agrees that it has not entered and will
         not enter into any contractual arrangement with respect to the
         distribution or delivery of the Series A Notes, except with its
         affiliates or with the prior consent of the Company.

                  (viii) Such Initial Purchaser further represents and agrees
         that (1) it has not offered or sold and will not offer or sell any
         Series A Notes to persons in the United Kingdom prior to the expiry of
         the period of six months from the issue date of the Series A Notes,
         except to persons whose ordinary activities involve them in acquiring,
         holding, managing or disposing of investments (as principal or agent)
         for the purposes of their business or otherwise in circumstances which
         have not resulted and will not result in an offer to the public in the
         United Kingdom within the meaning of the Public Offers of Securities
         Regulations 1995, (ii) it has complied and will comply with all
         applicable provisions of the Financial Services Act 1986 with respect
         to anything done by it in relation to the Series A Notes in, from or
         otherwise involving the United Kingdom and (iii) it has only issued or
         passed on and will only issue or pass on in the United Kingdom any
         document received by it in connection with the issuance of the
         Securities to a person who is of a kind described in Article 11(3) of
         the Financial Services Act of 1986 (Investment Advertisements)
         (Exemptions) Order 1996 or is a person to whom the document may
         otherwise lawfully be issued or passed on.

                  (ix) Such Initial Purchaser agrees that it will not offer,
         sell or deliver any of the Series A Notes in any jurisdiction outside
         the United States except under circumstances that will result in
         compliance with the applicable laws thereof, and that it will take at
         its own expense whatever action is required to permit its purchase and
         resale of the Series A Notes in such jurisdictions. Such Initial
         Purchaser understands that no action has been taken to permit a public
         offering in any jurisdiction outside the United States where action
         would be required for such purpose.

                  (x) Such Initial Purchaser agrees not to cause any
         advertisement of the Series A Notes to be published in any newspaper or
         periodical or posted in any public place and not to issue any circular
         relating to the Series A Notes, except such advertisements as include
         the statements required by Regulation S.

                  (xi) The sale of the Series A Notes in offshore transactions
         pursuant to Regulation S is not part of a plan or scheme to evade the
         registration provisions of the Act.

Each of the Initial Purchasers understands that the Company and, for purposes of
the opinions to be delivered to the Initial Purchasers pursuant to Section 8
hereof, counsel to the Company and counsel to the Initial Purchasers will rely
upon the accuracy and truth of the foregoing representations and hereby
expressly consents to such reliance.

         6.       Indemnification.

                  (a) The Company and its Subsidiaries, jointly and severally,
         agree to indemnify and hold harmless (i) each Initial Purchaser, (ii)
         each person, if any, who controls an Initial Purchaser within the
         meaning of Section 15 of the Act or Section 20(a) of the Exchange Act
         and (iii) the respective officers, directors, partners, employees,
         representatives and agents of any Initial Purchaser or any controlling
         person to the fullest extent lawful, from and against any and all
         losses, liabilities, claims, damages and expenses whatsoever (including
         but not limited to attorneys' fees and any and all expenses whatsoever
         incurred in investigating, preparing or defending against any
         investigation or litigation, commenced or threatened, or any claim
         whatsoever, and any and all amounts paid in settlement of any claim or
         litigation), joint or several, to which they or any of them may become
         subject under the Act, the Exchange Act or otherwise, insofar as such
         losses, liabilities, claims, damages or expenses (or actions in respect
         thereof) arise out of or are based upon any untrue statement or alleged
         untrue statement of a material fact contained in the Preliminary
         Offering Memorandum or the Offering Memorandum, or in any supplement
         thereto or amendment thereof, or arise out of or are based upon the
         omission or alleged omission to state therein a material fact required
         to be stated therein or necessary to make the statements therein, in
         the light of the circumstances under which they were made, not
         misleading; provided that the Company will not be liable in any such
         case to the extent, but only to the extent, that (i) any such loss,
         liability, claim, damage or expense arises out of or is based upon any
         such untrue statement or alleged untrue statement or omission or
         alleged omission made therein in reliance upon and in conformity with
         written information furnished to the Company by or on behalf of the
         Initial Purchasers expressly for use therein and (ii) the foregoing
         indemnity with respect to any untrue statement contained in or omitted
         from the Preliminary Offering Memorandum shall not inure to the benefit
         of any Initial Purchaser (or any person controlling such Initial
         Purchasers), from whom the person asserting any such loss, liability,
         claim, damage or expense purchased any of the Series A Notes which are
         the subject thereof if it is finally judicially determined that such
         loss, liability, claim, damage or expense resulted solely from the fact
         that such Initial Purchaser sold Series A Notes to the person asserting
         such loss, liability, claim, damage or expense, who was not sent or
         given, at or prior to the written confirmation of such sale, a copy of
         the Offering Memorandum, as amended or supplemented, and (x) the
         Company shall have previously and timely furnished sufficient copies of
         the Offering Memorandum, as so amended or supplemented, to such Initial
         Purchaser in accordance with this Agreement and (y) the Offering
         Memorandum, as so amended or supplemented, would have completely
         corrected such untrue statement or omission of a material fact. This
         indemnity agreement will be in addition to any liability which the
         Company may otherwise have, including, under this Agreement.

                  (b) Each Initial Purchaser, severally and not jointly, agrees
         to indemnify and hold harmless the Company and each person, if any, who
         controls the Company within the meaning of Section 15 of the Act or
         Section 20(a) of the Exchange Act, against any losses, liabilities,
         claims, damages and expenses whatsoever (including but not limited to
         attorneys' fees and any and all expenses whatsoever incurred in
         investigating, preparing or defending against any investigation or
         litigation, commenced or threatened, or any claim whatsoever and any
         and all amounts paid in settlement of any claim or litigation), joint
         or several, to which they or any of them may become subject under the
         Act, the Exchange Act or otherwise, insofar as such losses,
         liabilities, claims, damages or expenses (or actions in respect
         thereof) arise out of or are based upon any untrue statement or alleged
         untrue



<PAGE>



         statement of a material fact contained in the Preliminary Offering
         Memorandum or the Offering Memorandum, or in any amendment thereof or
         supplement thereto, or arise out of or are based upon the omission or
         alleged omission to state therein a material fact required to be stated
         therein or necessary to make the statements therein, in the light of
         the circumstances under which they were made, not misleading, in each
         case to the extent, but only to the extent, that any such loss,
         liability, claim, damage or expense arises out of or is based upon any
         untrue statement or alleged untrue statement or omission or alleged
         omission made therein in reliance upon and in conformity with written
         information furnished to the Company by or on behalf of any Initial
         Purchaser expressly for use therein; provided that in no case shall any
         Initial Purchaser be liable or responsible for any amount in excess of
         the discounts and commissions received by such Initial Purchasers, as
         set forth on the cover page of the Offering Memorandum. This indemnity
         will be in addition to any liability which any of the Initial
         Purchasers may otherwise have, including under this Agreement.

                  (c) Promptly after receipt by an indemnified party under
         subsection (a) or (b) above of notice of the commencement of any
         action, such indemnified party shall, if a claim in respect thereof is
         to be made against the indemnifying party under such subsection, notify
         each party against whom indemnification is to be sought in writing of
         the commencement thereof (but the failure so to notify an indemnifying
         party shall not relieve it from any liability which it may have under
         this Section 6 except to the extent that it has been actually
         prejudiced in any material respect by such failure or from any
         liability which it may otherwise have). In case any such action is
         brought against any indemnified party, and it notifies an indemnifying
         party of the commencement thereof, the indemnifying party will be
         entitled to participate therein, and to the extent it may elect by
         written notice delivered to the indemnified party promptly after
         receiving the aforesaid notice from such indemnified party, to assume
         the defense thereof with counsel reasonably satisfactory to such
         indemnified party. Notwithstanding the foregoing, the indemnified party
         or parties shall have the right to employ its or their own counsel in
         any such case, but the fees and expenses of such counsel shall be at
         the expense of such indemnified party or parties unless (i) the
         employment of such counsel shall have been authorized in writing by the
         indemnifying parties in connection with the defense of such action,
         (ii) the indemnifying parties shall not have employed counsel to take
         charge of the defense of such action within a reasonable time after
         notice of commencement of the action, or (iii) such indemnified party
         or parties shall have reasonably concluded that there may be defenses
         available to it or them which are different from or additional to those
         available to one or all of the indemnifying parties (in which case the
         indemnifying party or parties shall not have the right to direct the
         defense of such action on behalf of the indemnified party or parties),
         in any of which events such fees and expenses of counsel shall be borne
         by the indemnifying parties. The indemnifying party under subsection
         (a) or (b) above, shall only be liable for the legal expenses of one
         counsel (in addition to any local counsel) for all indemnified parties
         in each jurisdiction in which any claim or action is brought; provided
         that the indemnifying party shall be liable for separate counsel for
         any indemnified party in a jurisdiction, if counsel to the indemnified
         parties shall have reasonably concluded that there may be defenses
         available to such indemnified party that are difference from or
         additional to those available to one or more of the other indemnified
         parties and that separate counsel for such indemnified party is prudent
         under the circumstances. Anything in this subsection to the contrary
         notwithstanding, an indemnifying party shall not be liable for any
         settlement of any claim or action effected without its prior written
         consent; provided that such consent was not unreasonably withheld.

         7. Contribution. In order to provide for contribution in circumstances
in which the indemnification provided for in Section 6 is for any reason held to
be unavailable from the Company or is insufficient to hold harmless a party
indemnified thereunder, the Company and the Initial Purchasers shall contribute
to the aggregate losses, claims, damages, liabilities and expenses of the nature
contemplated by such indemnification provision (including any investigation,
legal and other expenses incurred in connection with, and any amount paid in
settlement of, any action, suit or proceeding or any claims asserted, but after
deducting in the case of losses, claims, damages, liabilities and expenses
suffered by the Company, any contribution received by the Company from persons,
other than the Initial Purchasers, who may also be liable for contribution,
including persons who control the Company within the meaning of Section 15 of
the Act or Section 20(a) of the Exchange Act) to which the Company and one or
more of the Initial Purchasers may be subject, in such proportion as is
appropriate to reflect the relative benefits received by the Company and the
Initial Purchasers from the offering of the Series A Notes or, if such
allocation is not permitted by applicable law or indemnification is not
available as a result of the indemnifying party not having received notice as
provided in Section 6, in such proportion as is appropriate to reflect not only
the relative benefits referred to above but also the relative fault of the
Company and the Initial Purchasers in connection with the statements or
omissions which resulted in such losses, claims, damages, liabilities or
expenses, as well as any other relevant equitable considerations. The relative
benefits received by the Company and the Initial Purchasers shall be deemed to
be in the same proportion as (x) the total proceeds from the offering of Series
A Notes (net of discounts but before deducting expenses) received by the Company
and (y) the discounts received by the Initial Purchasers, respectively, in each
case as set forth in the table on the cover page of the Offering Memorandum. The
relative fault of the Company and of the Initial Purchasers 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 or the Initial
Purchasers and the parties' relative intent, knowledge, access to information
and opportunity to correct or prevent such statement or omission. The Company
and the Initial Purchasers agree that it would not be just and equitable if
contribution pursuant to this Section 7 were determined by pro rata allocation
or by any other method of allocation which does not take into account the
equitable considerations referred to above. Notwithstanding the provisions of
this Section 7, (i) in no case shall any Initial Purchaser be required to
contribute any amount in excess of the amount by which the discount applicable
to the Series A Notes purchased by such Initial Purchaser pursuant to this
Agreement exceeds the amount of any damages which such Initial Purchaser has
otherwise been required to pay by reason of any untrue or alleged untrue
statement or omission or alleged omission and (ii) 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. For purposes of this Section 7, (A) each person,
if any, who controls any Initial Purchaser within the meaning of Section 15 of
the Act or Section 20(a) of the Exchange Act and (B) the respective officers,
directors, partners, employees, representatives and agents of any Initial
Purchaser or any controlling person shall have the same rights to contribution
as such Initial Purchaser, and each person, if any, who controls the Company
within the meaning of Section 15 of the Act or Section 20(a) of the Exchange Act
shall have the same rights to contribution as the Company, subject in each case
to clauses (i) and (ii) of this Section 7. Any party entitled to contribution
will, promptly after receipt of notice of commencement of any action, suit or
proceeding against such party in respect of which a claim for contribution may
be made against another party or parties under this Section 7, notify such party
or parties from whom contribution may be sought, but the failure to so notify
such party or parties shall not relieve the party or parties from whom
contribution may be sought from any obligation it or they may have under this
Section 7 or otherwise. No party shall be liable for contribution with respect
to any action or claim settled without its prior written consent; provided that
such written consent was not unreasonably withheld.

         dated the Closing Date, signed on behalf of the Company by (i) the

         not have been revoked) to the amendments (the "Amendments") to the
         indenture governing the 13% Notes (the "13% Notes Indenture"), set
         forth in the Company's Consent Solicitation Statement dated August 13,
         1997, as amended, relating to the 13% Notes and, prior to the Closing,
         the Company and the Trustee shall have executed a delivered a
         supplemental indenture to the 13% Notes Indenture (the "Supplemental
         Indenture") giving effect to the Amendments, and the Supplemental

                  (o) The Company has delivered to the Initial Purchasers true
         and correct executed copies of (i) that certain Equity Contribution and
         Exchange Agreement dated as of August 4, 1997 by and between the
         Company and Lenfest Telephony, Inc., that certain Partnership Agreement

         principles (regardless of whether enforcement is considered in a

         11.      Effective Date of Agreement; Termination

         Company if, on or prior to such date, (i) the Company shall have
         failed, refused or been unable to perform in any material respect any
         agreement on its part to be performed hereunder, (ii) any other
         condition to the obligations of the Initial Purchasers hereunder as
         provided in Section 8 is not fulfilled when and as required in any
         material respect, (iii) in the reasonable judgment of the Initial
         Purchasers any material adverse change shall have occurred since the
         respective dates as of which information is given in the Offering
         Memorandum in the condition (financial or otherwise), business,
         properties, assets, liabilities, prospects, net worth, results of
         operations or cash flows of the Company and the Subsidiaries taken as a
         whole, other than as set forth in the Offering Memorandum, or (iv)(A)
         any domestic or international event or act or occurrence has materially
         disrupted, or in the opinion of the Initial Purchasers will in the

         authorities, or a moratorium in foreign exchange trading by major
         international banks or persons shall have been declared; or (D) there
         is an outbreak or escalation of armed hostilities involving the United
         States on or after the date hereof, or there has been a declaration by
         the United States of a national emergency or war, the effect of which
         shall, in the Initial Purchasers' judgment, make it inadvisable or
         impracticable to proceed with the offering or delivery of the Series A
         Notes on the terms and in the manner contemplated in the Offering
         Memorandum; or (E) there has been a material adverse change in general
         economic, political or financial conditions in the United States, or
         the effect of international conditions on the financial markets in the
         United States shall be such that, it is, in the Initial Purchasers'
         judgment, inadvisable or impracticable to proceed with the delivery of
         the Series A Notes as contemplated hereby.

                  (c) Any notice of termination pursuant to this Section 11
         shall be by telephone, telex, telephonic facsimile, or telegraph,
         confirmed in writing by letter.

                  (d) If this Agreement shall be terminated pursuant to any of
         the provisions hereof (otherwise than pursuant to any of clauses (iii)
         or (iv) of Section 11(b), in which case each party will be responsible
         for its own expenses), or if the sale of the Series A Notes provided
         for herein is not consummated because any condition to the obligations
         of the Initial Purchasers set forth herein is



<PAGE>



         not satisfied or because of any refusal, inability or failure on the
         part of the Company to perform any agreement herein or comply with any
         provision hereof, the Company will, subject to demand by the Initial
         Purchasers, reimburse the Initial Purchasers for all out-of-pocket
         expenses (including the reasonable fees and expenses of Initial
         Purchasers' counsel), incurred by the Initial Purchasers in connection

                      Form of Opinion of Buchanan Ingersoll


                  1. Each of the Company and the Subsidiaries is duly organized
         and validly existing as a corporation in good standing under the laws
         of its jurisdiction of incorporation, and has all requisite corporate
         power and authority to carry on its business as it is being conducted
         and as described in the Offering Memorandum and to own, lease and
         operate its properties, and is duly qualified and in good standing as a
         foreign corporation 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.

                  2. Each of the Joint Ventures is duly formed and valid
         existing as a partnership in good standing under the laws of its
         jurisdiction of incorporation, and has all requisite corporate power
         and authority to carry on its business as it is being conducted and as
         described in the Offering Memorandum and to own, lease and operate its
         properties, and is duly qualified and in good standing as a partnership
         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.

                  3. All of the outstanding shares of capital stock of the
         Company have been duly authorized, validly issued, and are fully paid
         and nonassessable and were not issued in violation of any preemptive or
         similar rights. All of the outstanding shares of capital stock of the
         Company is set forth in the Offering Memorandum under the caption
         "Capitalization."

                  4.       All of the partnership interests owned the Company 
         and each Subsidiary have been duly authorized and validly issued.

                  5. 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 Offering Memorandum,
         currently, and will not be following the Offering, 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.

                  6. When the Series A Notes are issued and delivered pursuant
         to this Agreement, no Series A Note will be of the same class (within
         the meaning of Rule 144A under the Act) as securities of the Company
         that are listed on a national securities exchange registered under
         Section 6 of the Exchange Act or that are quoted in a United States
         automated inter-dealer quotation system.

                  7.       The Company has all requisite corporate power and 
         authority to execute, deliver and




<PAGE>



         perform its obligations under this Agreement, the Indenture, the Escrow
         and Disbursement Agreement, the Pledge Agreement, the Registration
         Rights Agreement and the other Operative Documents, as applicable, and
         to consummate the transactions contemplated thereby, including, without
         limitation, the corporate power and authority to issue, sell and
         deliver the Securities as provided herein and therein.

                  8.       This Agreement has been duly and validly authorized,
         executed and delivered by the Company.

                  9. Each of the Indenture, the Escrow and Disbursement
         Agreement, the Pledge Agreement and the Registration Rights Agreement,
         the Warrant Registration Rights Agreement and the Company Pledge
         Agreement has been duly and validly authorized, executed and delivered
         by the Company and is the valid and binding obligation of the Company,
         enforceable against the Company in accordance with its terms, except
         that (a) such enforceability may be limited by bankruptcy, insolvency,
         fraudulent conveyance, reorganization, moratorium (whether general or
         specific) or similar laws now or hereafter in effect relating to or
         affecting creditors' rights and remedies generally, (b) such
         enforceability may be limited by the effects of general principals of
         equity and by the discretion of the court before which any proceeding
         therefor may be brought (whether such proceeding is at law or in equity
         or in a bankruptcy proceeding), (c) rights to contribution or
         indemnification may be limited by the laws, rules or regulations of any
         governmental authority or agency thereof or by public policy, and (d)
         waivers as to usury, stay or extension laws may be unenforceable.

                  10. The Series A Notes have been duly and validly authorized
         for issuance and sale to the Initial Purchasers by the Company pursuant
         to this Agreement and, when issued and authenticated in accordance with
         the terms of the Indenture and delivered against payment therefor in
         accordance with the terms of this Agreement and the Indenture, will be
         the valid and binding obligations of the Company, enforceable against
         the Company in accordance with their terms and entitled to the benefits
         of the Indenture, except that (a) such enforceability may be limited by
         bankruptcy, insolvency, fraudulent conveyance, reorganization,
         moratorium (whether general or specific) or similar laws now or
         hereafter in effect relating to or affecting creditors' rights and
         remedies generally, (b) such enforceability may be limited by the
         effects of general principals of equity and by the discretion of the
         court before which any proceeding therefor may be brought (whether such
         proceeding is at law or in equity or in a bankruptcy proceeding), (c)
         rights to contribution or indemnification may be limited by the laws,
         rules or regulations of any governmental authority or agency thereof or
         by public policy, and (d) waivers as to usury, stay or extension laws
         may be unenforceable.

                  11. The Series B Notes have been duly and validly authorized
         for issuance by the Company and, when issued and authenticated in
         accordance with the terms of the Exchange Offer and the Indenture, will
         be the valid and binding obligations of the Company, enforceable
         against the Company in accordance with their terms and entitled to the
         benefits of the Indenture, except that (a) such enforceability may be
         limited by bankruptcy, insolvency, fraudulent conveyance,
         reorganization, moratorium (whether general or specific) or similar
         laws now or hereafter in effect relating to or affecting creditors'
         rights and remedies generally, (b) such enforceability may be limited
         by the effects of general principals of equity and by the discretion of
         the court before which




<PAGE>



         any proceeding therefor may be brought (whether such proceeding is at
         law or in equity or in a bankruptcy proceeding), (c) rights to
         contribution or indemnification may be limited by the laws, rules or
         regulations of any governmental authority or agency thereof or by
         public policy, and (d) waivers as to usury, stay or extension laws may
         be unenforceable.


                  12. The Offering Memorandum contains a fair summary of each of
         the Series A Notes, the Indenture, the Escrow and Disbursement
         Agreement, the Pledge Agreement and the Registration Rights Agreement.

                  13. No registration under the Act of the Series A Notes is
         required for the sale of the Series A Notes to the Initial Purchasers
         as contemplated by this Agreement or for the Exempt Resales assuming
         (i) that the Initial Purchasers are Qualified Institutional Buyers, as
         defined in Rule 144A under the Act ("QIBs") or that the Series A Notes
         are purchased in an offshore transaction within the meaning of
         Regulation S, (ii) that the purchasers who buy the Units in the Exempt
         Resales are QIBs, (iii) the accuracy of the Initial Purchasers'
         representations regarding the absence of general solicitation in
         connection with the sale of the Series A Notes to the Initial
         Purchasers and the Exempt Resales contained in this Agreement and (iv)
         the accuracy of the Company's representations in Sections 5(a)(ii),
         (xxi), (xxix) and (xxxiii) (other than with respect to the first
         sentence) of this Agreement.

                  14. The Offering Memorandum, as of its date (except for the
         financial statements, including the notes thereto, and supporting
         schedules and other financial, statistical and accounting data included
         therein or omitted therefrom, as to which no opinion need be
         expressed), and each amendment or supplement thereto, as of its date,
         contains all the information specified in, and meets the requirements
         of, Rule 144A(d)(4) under the Act.

                  15.      Prior to the Registered Exchange Offer or the 
         effectiveness of the Shelf Registration Statement, the Indenture is not
         required to be qualified under the Trust Indenture Act.

                  16. None of (A) the execution, delivery or performance by the
         Company of this Agreement and the other Operative Documents, (B) the
         issuance and sale of the Series A Notes or (C) consummation by the
         Company and the Subsidiaries of the transactions described in the
         Offering Memorandum 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 a party or by which it or its property is or may be bound
         identified to such 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




<PAGE>



         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 Offering
         Memorandum. 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 and
         qualification of the Indenture under the Trust Indenture Act of 1939,
         as amended, in connection with the Registration Rights Agreement, 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 this Agreement
         and the other Operative Documents, as applicable, (2) the issuance and
         sale of the Series A Notes or (3) consummation by the Company, the
         Subsidiaries and the Joint Ventures of the transactions described in
         the Offering Memorandum, except such as have been obtained and made or
         have been disclosed in the Offering Memorandum, and except where the
         failure to obtain such consents or waivers would not, singly or in the
         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,
         the Subsidiaries and the Joint Ventures of this Agreement and the other
         Operative Documents or the issuance and sale of the Series A Notes, as
         applicable, other than such consents and waivers as have been obtained.

                  17. 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.

                  18. Except as set forth in this Agreement or the Registration
         Rights Agreement, there are no holders of securities of the Company
         who, by reason of the execution by the Company of this Agreement or any
         other Operative Document to which it is a party 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.

                  19. None of (A) the execution, delivery and performance of
         this Agreement or any of the Operative Documents, (B) the purchase of
         the Pledged Securities pursuant to the Escrow and Disbursement
         Agreement, (C) the pledge of the Stock Collateral pursuant to the
         Pledge Agreement, (D) the issuance and sale of the Series A Notes, (E)
         the application of the proceeds from the issuance and sale of the
         Series A Notes or (F) the consummation of the transactions contemplated
         in connection with any of the foregoing as set forth in the Offering
         Memorandum, will violate Regulations G, T, U or X promulgated by the
         Board of Governors of the Federal Reserve System.

                  20. The provisions of the Escrow and Disbursement Agreement
         are effective to create valid security interests in favor of the
         Trustee for the benefit of the holders of the Senior Notes in that
         portion of the collateral described in the Escrow and Disbursement
         Agreement that is subject to Article 9 of the Uniform Commercial Code
         of the State of New York (such collateral, the "Collateral" and such
         statute the "New York UCC") as security for the payment of the Secured
         Obligations (as defined in the Escrow and Disbursement Agreement) to
         the extent set forth in the Escrow and Disbursement Agreement.




<PAGE>




                  21. To the extent that the Escrow Account (as defined in the
         Escrow and Disbursement Agreement) is a "deposit account" (as defined
         in Section 9-105(1)(e) of the New York UCC) that (a) is duly
         established and maintained in the name of "[__________________], as
         collateral agent, for the benefit of Hyperion Telecommunications, Inc.
         Senior Note Holders" with [____________________________________], in
         its capacity as collateral agent for the Trustee and the holders of the
         Notes (the "Escrow Agent"), in New York, New York, (b) remains at all
         times subject to the sole dominion and control of the Trustee, and (c)
         is not evidenced at any time by an indispensable instrument, the
         provisions of the Escrow and Disbursement Agreement, together with such
         dominion and control, are effective under the laws of the State of New
         York to create in favor of the Trustee, for the benefit of the Trustee
         and the holders of the Senior Notes, a security interest in, and a lien
         on, such deposit account to secure the Secured Obligations to the
         extent set forth in the Escrow and Disbursement Agreement. Such
         security interest and lien will be prior to the interest of a judgment
         lien creditor subsequently attaching or levying against the Escrow
         Account or a bankruptcy trustee claiming the rights of a hypothetical
         lien creditor pursuant to Section 544 of the Bankruptcy Code.

                  22. The financing statements naming the Company as debtor and
         the Trustee as secured party, together with all schedules and exhibits
         thereto (together, the "Financing Statements"), to be filed in each of
         the filing offices (collectively, the "Filing Offices"), are in
         appropriate form for filing with the appropriate jurisdictions. Upon
         the proper filing of the Financing Statements in the Filing Offices,
         the security interest in favor of the Trustee in the Collateral
         described in the Financing Statements will be perfected to the extent a
         security interest in such Collateral can be perfected by filing a
         financing statement under the provisions of the New York UCC or the
         other applicable UCCs (to the extent the UCC as in effect in a
         jurisdiction in which the opinion giver is not admitted to practice,
         the opinion given may rely exclusively on the CCH Secured Transactions
         Guide, or similar publication by service, as applicable).

                  23. The provisions of the Escrow and Disbursement Agreement,
         together with (i) delivery to the Escrow Agent in the State of New York
         of the certificates or instruments representing those Government
         Securities (as defined in the Escrow and Disbursement Agreement) that
         constitute "certificated securities" (as defined in Section 8-102 of
         the New York U.C.C.) or "negotiable instruments" (as defined in Section
         3-104 of the New York U.C.C.) and related executed blank instruments of
         transfer, and (ii) registration in the name of the Escrow Agent, as
         pledgee, of those Government Securities that constitute "uncertificated
         securities" (as defined in Article 8 of the New York U.C.C.) are
         sufficient to create in favor of the Escrow Agent a valid and perfected
         security interest in all right, title and interest of the Company in
         such Government Securities to the extent such creation and perfection
         are governed by the New York U.C.C. Upon such delivery or registration
         and assuming that the Escrow Agent acquires its security interest in
         those Government Securities that constitute "securities" (as defined in
         Section 8-102 of the New York U.C.C.) in good faith without knowledge
         of adverse claims, the Escrow Agent will acquire its security interest
         in those Government Securities that constitute securities free of
         adverse claims (including other consensual security interests). The
         security interest in the Government Securities will be a valid,
         perfected security interest (with priority over (i) other consensual
         security interests, (ii) interests of judgment lien creditors
         subsequently attaching or levying against such collateral or (iii) the
         interests of a bankruptcy trustee claiming the rights of a hypothetical
         lien creditor pursuant to Section 544 of the Bankruptcy Code) if such
         Government Securities are registered in the name of the Escrow

         Agent on the records of the Federal Reserve Bank of New York. No
         governmental filings or recordings are required in order to perfect (or
         maintain the perfection of) the security interests created in
         Government Securities.

                  24. The provisions of the Pledge Agreement, together with
         delivery to the Collateral Agent in the State of New York of the
         certificates representing the shares identified on Schedule I to the
         Pledge Agreement ( the "Pledged Shares") and blank stock powers with
         respect thereto signed by the Company, are sufficient to create in
         favor of the Collateral Agent a valid and perfected security interest
         under the New York U.C.C. in all right, title and interest of the
         Company in the Pledged Shares. Upon such delivery and assuming that the
         Collateral Agent acquires its security interest in the Pledged Shares
         without knowledge of any adverse claims, the Collateral Agent will
         acquire its security interest in the Pledged Shares free of adverse
         claims (including other consensual security interests). No governmental
         filings or recordings are required in order to perfect (or maintain the
         perfection of) the security interests created in the Pledged Shares.

                  25. 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
         Preliminary Offering Memorandum and the Offering Memorandum 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, restraining
         orders or other orders by the FCC or any similar state regulatory
         commission or body.

                  We have participated in conferences with officers and other
         representatives of the Company, representatives of the independent
         certified public accountants of the Company and the Initial Purchasers
         and its representatives at which the contents of the Preliminary
         Offering Memorandum and the Offering Memorandum and related matters
         were discussed and, although we have not undertaken to investigate or
         verify independently, and do not assume any responsibility for, the
         accuracy, completeness or fairness of the statements contained in the
         Preliminary Offering Memorandum or the Offering Memorandum (except as
         indicated above), on the basis of the foregoing, no facts have come to
         our attention which led us to believe that the Preliminary Offering
         Memorandum or the Offering Memorandum, as of its date or the Closing
         Date, contained an untrue statement of a material fact or omitted to
         state any fact required to be stated therein or necessary to make the
         statements therein, in the light of the circumstances under which they
         were made, not misleading (except as to financial statements and
         related notes, the financial statement schedules and other financial
         and statistical data included therein).

         of the licenses, permits and authorizations, if any, required by the
         FCC and the State Regulatory Agencies for the provision of

         as a whole.

         2. Neither the Company, any Subsidiaries nor any Joint Ventures is
         subject to any pending complaint or investigation before the FCC or, to

         or investigation before any State Regulatory Agencies based on any
         alleged violation by the Company, the Subsidiaries or the Joint
         Ventures in connection with their provision of or failure to provide
         telecommunications services.

         3. The statements in the Offering Memorandum under the heading of ARisk

         consummation of the transactions contemplated in the Purchase Agreement
         except where the failure to obtain the consents, approvals,
         authorizations, licenses, certificates, permits or orders would not
         have a Material Adverse Effect on the Company, the Subsidiaries and the
         Joint Ventures, taken as a whole.

         5. Neither the execution and delivery of the Purchase Agreement and the
         Operative Documents nor the sale of the Series A Notes and the related
         pledges of the Stock Collateral contemplated thereby will conflict with
         or result in a violation of any order or regulation of the FCC or any
         State Regulatory Agency applicable to the Company, its Subsidiaries or
         the Joint Ventures except where the conflict with or the violation of
