Item 5.  Other Events
- ---------------------

          On October 31, 1997, Intermedia Communications Inc. (the "Company")
announced the completion of two concurrent private offerings (the "Offerings")
of $250 million principal amount of 8 7/8% Senior Notes due 2007 (the "Senior
Notes") and $175 million liquidation preference of Depositary Shares (the
"Depositary Shares"), each representing a one-hundredth interest in a share of
the Company's Series E Junior Convertible Preferred Stock, resulting in gross
proceeds to the Company of $425 million. A copy of the press release announcing
the completion of the Offerings is filed herewith as Exhibit 99.1. Subsequent
thereto, the over-allotment option with respect to the private placement of
Depositary Shares was exercised and the Company sold an additional 1,000,000
Depositary Shares for additional aggregate gross proceeds of approximately
$25,000,000.

          The net proceeds from the offering of the Depositary Shares will be
used by the Company to finance the continued expansion of the Company's
telecommunications networks, including but not limited to, network electronics,
such as local/long distance voice and data switches, and for general corporate
purposes, including working capital. The net proceeds from the offering of the
Senior Notes will be used to fund up to 80% of the cost of acquisition or
construction by the Company of telecommunications related assets. A portion of
the Company's expansion may occur through acquisitions (utilizing cash or
securities of the Company) as an alternative to direct investments in the assets
required to implement the expansion.

          The Senior Notes and the Depositary Shares sold in the Offerings will
not and have not been registered under the Securities Act or any state
securities or blue sky laws, and may not be offered or sold in the United States
or in any state thereof absent registration or an applicable exemption from the
registration requirements of such laws.

<PAGE>
 
if not listed or admitted to trading on any national securities exchange, on the
Nasdaq National Market or, if such shares are not listed or admitted to trading
on any national securities exchange or quoted on Nasdaq National Market but the
issuer is a Foreign Issuer (as defined in Rule 3b-4(b) under the Exchange Act)
and the principal securities exchange on which such shares are listed or

not rank prior, as to the payment of dividends or as to the distribution of
assets upon any voluntary or involuntary liquidation, dissolution or winding up
of such Person, to shares of Capital Stock of any other class of such Person.

     "Consolidated Cash Flow Leverage Ratio" with respect to any Person means
the ratio of the Consolidated Indebtedness of such Person to the Consolidated
EBITDA of such Person for the relevant period; provided, however, that (1) if
the Company or any Subsidiary of the Company has incurred any Indebtedness
(including Acquired Debt) or if the Company has issued any Disqualified Stock or
if any Subsidiary of the Company has issued any Preferred Stock since the
beginning of such period that remains outstanding on the date of such
determination or if the transaction giving rise to the need to calculate the
Consolidated Cash Flow Leverage Ratio is an incurrence of Indebtedness
(including Acquired Debt) or the issuance of Disqualified Stock by the Company,
Consolidated EBITDA and Consolidated Indebtedness for such period will be
calculated after giving effect on a pro forma basis to (A) such Indebtedness,
Disqualified Stock or Preferred Stock, as applicable, as if such Indebtedness
had been incurred or such stock had been issued on the first day of such period,
(B) the discharge of any other Indebtedness repaid, repurchased, defeased or
otherwise discharged with the proceeds of such new Indebtedness or sale of stock
as if such discharge had occurred on the first day of such period, and (C) the
interest income realized by the Company or its Subsidiaries on the proceeds of
such Indebtedness or of such stock sale, to the extent not yet applied at the
date of determination, assuming such proceeds earned interest at the rate in
effect on the date of determination from the first day of such period through
such date of determination, (2) if since the beginning of such period the
Company or any Subsidiary of the Company has made any sale of assets (including,
without limitation, any Asset Sales or pursuant to any Sale and Leaseback
Transaction), Consolidated EBITDA for such period will be (A) reduced by an
amount equal to Consolidated EBITDA (if positive) directly attributable to the
assets which are the subject of such sale of assets for such period or (B)
increased by an amount equal to Consolidated EBITDA (if negative) directly
attributable thereto for such period and (3) if since the beginning of such
period the Company or any Subsidiary of the Company (by merger or otherwise) has
made an Investment in any Subsidiary of the Company (or any Person which becomes
a Subsidiary of the Company) or has made an acquisition of assets, including,
without limitation, any acquisition of assets occurring in connection with a
transaction causing a calculation of Consolidated EBITDA to be made hereunder,
which constitutes all or substantially all of an operating unit of a business,
Consolidated EBITDA for such period will be calculated after giving pro forma
effect thereto (including the incurrence of any Indebtedness (including Acquired
Debt)) as if such Investment or acquisition occurred on the first day of such
period.  For purposes of this definition, whenever pro forma effect is to be
given to an acquisition of assets, the pro forma calculations will be determined
in good faith by a responsible financial or accounting Officer of 

                                       3
<PAGE>
 
the Company, provided, however, that such Officer shall assume (i) the
historical sales and gross profit margins associated with such assets for any
consecutive 12-month period ended prior to the date of purchase (provided that
the first month of such 12-month period will be no more than 18 months prior to
such date of purchase) and (ii) other expenses as if such assets had been owned
by the Company since the first day of such period. If any Indebtedness
(including, without limitation, Acquired Debt) bears a floating rate of interest
and is being given pro forma effect, the interest on such Indebtedness will be
calculated as if the rate in effect on the date of determination had been the
applicable rate for the entire period.


     "Consolidated EBITDA" as of any date of determination means the
Consolidated Net Income for such period (but without giving effect to
adjustments, accruals, deductions or entries resulting from purchase accounting,
extraordinary losses or gains and any gains or losses from any Asset Sales),
plus the following to the extent deducted in calculating such Consolidated Net
Income: (i) provision for taxes based on income or profits of such Person and
its Subsidiaries for such period, (ii) Consolidated Interest Expense, (iii)
depreciation, amortization (including amortization of goodwill and other
intangibles) and other non-cash charges (excluding any such non-cash charge to
the extent that it represents an accrual of or reserve for cash charges in any
future period or amortization of a prepaid cash expense that was paid in a prior
period and excluding non-cash interest and dividend income) of such Person and
its Subsidiaries for such period, in each case, on a consolidated basis and
determined in accordance with GAAP. Notwithstanding the foregoing, the provision
for taxes on the income or profits of, and the depreciation, amortization,
interest expense and other non-cash charges of, a Subsidiary of the referent
Person shall be added to Consolidated Net Income to compute Consolidated EBITDA
only to the extent (and in same proportion) that the Net Income of such
Subsidiary was included in calculating the Consolidated Net Income of such
Person and only if a corresponding amount would be permitted at the date of
determination to be dividended to the Company by such Subsidiary, or loaned to
the Company by any such Subsidiary, without prior approval (that has not been
obtained), pursuant to the terms of its charter and all agreements, instruments,
judgments, decrees, orders, statutes, rules and governmental regulations
applicable to that Subsidiary or its stockholders.

     "Consolidated Indebtedness" means, with respect to any Person, as of any
date of determination, the aggregate amount of Indebtedness of such Person and
its Subsidiaries as of such date calculated on a consolidated basis in
accordance with GAAP consistently applied.

     "Consolidated Interest Expense" means, for any Person, for any period, the
aggregate of the following for such Person for such period determined on a
consolidated basis in accordance with GAAP: (a) the amount of interest in
respect of Indebtedness (including amortization of original issue discount,
amortization of debt issuance costs, and non-cash interest payments on any
Indebtedness, the interest portion of any deferred payment obligation and after
taking into account the effect of elections made under any Interest Rate
Agreement, however denominated, with respect to such Indebtedness), (b) the
amount of Redeemable Dividends (to the extent not already included in
Indebtedness in determining Consolidated Interest Expense for the relevant
period) and (c) the interest component of rentals in respect of any Capital
Lease Obligation paid, in each case whether accrued or scheduled to be paid or
accrued by such Person during such period to the extent such amounts were
deducted in computing Consolidated Net Income, determined on a consolidated
basis in accordance with GAAP.  For purposes of this definition, interest on a
Capital Lease Obligation shall be deemed to accrue at an interest rate
reasonably determined by such Person to be the rate of interest implicit in such
Capital Lease Obligation in accordance with GAAP consistently applied.

                                       4
<PAGE>
 
     "Consolidated Net Income" means, with respect to any Person for any
period, the aggregate of the Net Income of such Person and its Subsidiaries for
such period, on a consolidated basis, determined in accordance with GAAP;

accounted for by the equity method of accounting shall be included only to the
extent of the amount of dividends or distributions paid in cash to the referent
Person or a Subsidiary thereof,

     (ii)   the Net Income of any Subsidiary shall be excluded to the extent
that the declaration or payment of dividends or other distributions by that
Subsidiary of that Net Income is not at the date of determination permitted
without any prior governmental approval (which has not been obtained) or,
directly or indirectly, by operation of the terms of its charter or any
agreement, instrument, judgment, decree, order, statute, rule or governmental
regulation applicable to that Subsidiary or its stockholders,

     (iii)  the Net Income of any Person acquired in a pooling of interests
transaction for any period prior to the date of such acquisition shall be
excluded,

     (iv)   the cumulative effect of a change in accounting principles shall be
excluded, and

     (v)    the Net Income of any Unrestricted Subsidiary shall be excluded,
whether or not distributed to the Company or one of its Subsidiaries.

     "Contingent Investment" means, with respect to any Person, any guarantee
by such Person of the performance of another Person or any commitment by such
Person to invest in another Person.  Any Investment that consists of a
Contingent Investment shall be deemed made at the time that the guarantee of
performance or the commitment to invest is given, and the amount of such
Investment shall be the maximum monetary obligation under such guarantee of
performance or commitment to invest.  To the extent that a Contingent Investment
is released or lapses without payment under the guarantee of performance or the
commitment to invest, such Investment shall be deemed not made to the extent of
such release or lapse.  With respect to any Contingent Investment, the payment
of the guarantee of performance or the payment under the commitment to invest
shall not be deemed to be an additional Investment.

     "Continuing Directors" means, as of any date of determination, any member
of the Board of Directors of the Company who (i) was a member of such Board of

Section 2.01.  Form and Dating.

     The Senior Notes and the Trustee's certificate of authentication shall be
substantially in the form of Exhibit A hereto, the terms of which are
incorporated in and made a part of this Indenture.  The Senior Notes may have
notations, legends or endorsements required by law, stock exchange rule or
usage.  Each Senior Note shall be dated the date of its authentication.  The
Senior Notes shall be in denominations of $1,000 and integral multiples thereof.

     The terms and provisions contained in the Senior Notes shall constitute,
and are hereby expressly made, a part of this Indenture and the Company and the
Trustee, by their execution and delivery of this Indenture, expressly agree to
such terms and provisions and to be bound thereby.  However, to the extent any
provision of any Senior Note conflicts with the express provisions of this
Indenture, the provisions of this Indenture shall govern and be controlling.

     Senior Notes issued in global form shall be substantially in the form of
Exhibit A attached hereto (including the Global Security Legend and the
"Schedule of Exchanges in the Global Security" attached thereto).  Senior Notes
issued in definitive form shall be substantially in the form of Exhibit A
attached hereto (but without the Global Security Legend and without the
"Schedule of Exchanges of Interests in the Global Security" attached thereto).
Each Global Security shall represent such of the outstanding Senior Notes as
shall be specified therein and each shall provide that it shall represent the
aggregate principal amount of outstanding Senior Notes from time to time
endorsed thereon and that the aggregate principal amount of outstanding Senior
Notes represented thereby may from time to time be reduced or increased, as
appropriate, to reflect exchanges and redemptions. Any endorsement of a Global
Security to reflect the amount of any increase or decrease in the aggregate
principal amount of outstanding Senior Notes represented thereby shall be made
by the Trustee or the Note Custodian, at the direction of the Trustee, in
accordance with instructions given by the holder thereof as required by Section

Section 2.02.  Execution and Authentication.

     One Officer of the Company shall sign the Senior Notes for the Company by
manual or facsimile signature.

     If an Officer whose signature is on a Senior Note no longer holds that
office at the time a Senior Note is authenticated, the Senior Note shall
nevertheless be valid.  In addition, if a Person is not an Officer at the time a
Senior Note is authenticated, but becomes an Officer on or prior to the delivery
of the Senior Note, the Senior Note shall nevertheless be valid.

     A Senior Note shall not be valid until authenticated by the manual
signature of an authorized signatory of the Trustee. The signature of the
Trustee shall be conclusive evidence that the Senior Note has been authenticated
under this Indenture.

     The Trustee shall, upon a written order of the Company signed by an Officer
of the Company, authenticate Senior Notes for original issue up to the aggregate
principal amount stated in paragraph 4 of the Senior Notes. The aggregate
principal amount of Senior Notes outstanding at any time may not exceed such
amount except as provided in Section 2.07 hereof.

     The Trustee may appoint an authenticating agent acceptable to the Company
to authenticate Senior Notes.  Unless limited by the terms of such appointment,
an authenticating agent may authenticate Senior Notes whenever the Trustee may
do so.  Each reference in this Indenture to authentication by the Trustee
includes authentication by such agent.  An authenticating agent has the same
rights as an Agent to deal with the Company or an Affiliate of the Company.


Section 2.03.  Registrar and Paying Agent.

     The Company shall maintain an office or agency where Senior Notes may be
presented for registration of transfer or for exchange ("Registrar") and an
office or agency where Senior Notes may be presented for payment ("Paying
Agent").  The Registrar shall keep a register of the Senior Notes and of their
transfer and exchange.  The Company may appoint one or more co-registrars and
one or more additional paying agents.  The term "Registrar" includes any co-
registrar and the term "Paying Agent" includes any additional paying agent.  The
Company may change any Paying Agent or Registrar without notice to any holder.
The Company shall notify the Trustee and the Trustee shall notify the holders of
the Senior Notes in writing of the name and address of any Agent not a party to
this Indenture.  If the Company fails to appoint or maintain another entity as
Registrar or Paying Agent, the Trustee shall act as such. The Company or any of
its Subsidiaries may act as Paying Agent or Registrar. The Company shall enter
into an appropriate agency agreement with any Agent not a party to this
Indenture, which shall incorporate the provisions of the TIA. The agreement
shall implement the provisions of this Indenture that relate to such Agent. The
Company shall notify the Trustee of the name and address of any such Agent. If
the Company fails to maintain a Registrar or Paying Agent, or fails to give the
foregoing notice, the Trustee shall act as such, and shall be entitled to
appropriate compensation in accordance with Section 7.07 hereof.

in writing that the Paying Agent shall hold in trust for the benefit of holders
or the Trustee all money held by the Paying Agent for the payment of principal,
premium or Liquidated Damages, if any, or interest on the Senior Notes, and will

While any such default continues, the Trustee may require a Paying Agent to pay
all money held by it to the Trustee. The Company at any time may require a
Paying Agent to pay all money held by it to the Trustee. Upon payment over to
the Trustee, the Paying Agent (if other than the Company or a Subsidiary) shall
have no further liability for the money. If the Company or a Subsidiary acts as
Paying Agent, it shall segregate and hold in a separate trust fund for the
benefit of the holders all money held by it as Paying Agent. Upon any bankruptcy
or reorganization proceedings relating to the Company, the Trustee shall serve
as Paying Agent and Registrar for the Senior Notes.

Depositary, or by the Depositary or any such nominee to a successor Depositary
or a nominee of such successor Depositary. All Global Securities will be

to the Trustee notice from the Depositary that it is unwilling or unable to
continue to act as Depositary or that it is no longer a clearing agency
registered under the Exchange Act and, in either case, a successor Depositary is
not appointed by the Company within 120 days after the date of such notice from
the Depositary or (ii) the Company

in part) should be exchanged for Certificated Securities and delivers a written
notice to such effect to the Trustee. Upon the occurrence of either of the
preceding events in (i) or (ii) above, Certificated Securities shall be issued
in such names as the Depositary shall instruct the Trustee. Global Securities
also may be exchanged or replaced, in whole or in part, as provided in Sections
2.07 and 2.10 hereof. Every Senior Note authenticated and delivered in exchange
for, or in lieu of, a Global Security or any portion thereof, pursuant to this
Section 2.06 or Section 2.07 or 2.10 hereof, shall be authenticated and
delivered in the form of, and shall be, a Global Security. A Global Security may
not be exchanged for another Senior Note other than as provided in this Section

and exchanged as provided in Section 2.06(b), (c) or (f) hereof.

     (b) Transfer and Exchange of Beneficial Interests in the Global Securities.
The transfer and exchange of beneficial interests in the Global Securities shall

Indenture and the Applicable Procedures. Beneficial interests in the Restricted
Global Securities shall be subject to restrictions on transfer comparable to
those set forth herein to the extent required by the Securities Act. The Trustee
shall have no obligation to ascertain the Depositary's compliance with any such
restrictions on transfer. Transfers of beneficial interests in the Global
Securities also shall require compliance with either subparagraph (i) or (ii)
below, as applicable, as well as one or more of the other following
subparagraphs as applicable:

     (i) Transfer of Beneficial Interests in the Same Global Security.

  set forth in the Private Placement Legend; provided, however, that prior to
  the expiration of the Restricted Period, transfers of beneficial interests in
  the Regulation S Global Security may not be made to a U.S. Person or for the
  account or benefit of a U.S. Person (other than an Initial Purchaser).
  Beneficial interests in any Unrestricted Global Security may be transferred
  only to Persons who take delivery thereof in the form of a beneficial interest
  in an Unrestricted Global Security. No written orders or instructions shall be
  required to be delivered to the Registrar to effect the transfers described in
  this Section 2.06(b)(i).

     (ii) All Other Transfers and Exchanges of Beneficial Interests in Global
  Securities. In connection with all transfers and exchanges of beneficial

  to Persons who take delivery thereof in the form of a beneficial interest in
  the same Global Security), the transferor of such beneficial interest must
  deliver to the Registrar either (A) (1) a written order from a Participant or
  an Indirect Participant given to the Depositary in accordance with the
  Applicable Procedures directing the Depositary to credit or cause to be

  containing information regarding the Person in whose name such Certificated
  Security shall be registered to effect the transfer or exchange referred to in

     Security. Beneficial interests in any Restricted Global Security may be

and the Trustee receives evidence to their satisfaction of the destruction, loss
or theft of any 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 Note is replaced. The Company may charge for its
expenses in replacing a Note.

          Every replacement 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 Notes duly issued hereunder.

Section 2.08.  Outstanding 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 and those described in this Section 2.08 as not
outstanding.  Except as set forth in Section 2.09 hereof, a Note does not cease
to be outstanding because the Company or an Affiliate of the Company holds the
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) segregates and holds in trust, in accordance with this
Indenture, on a redemption date or maturity date, 

                                      31
<PAGE>
 
money sufficient to pay all principal and interest, if any, payable on that date
with respect to the Senior Notes (or the portion thereof to be redeemed or
maturing, as the case may be), then on and after that date such Senior Notes (or
portions thereof) shall be deemed to be no longer outstanding and shall cease to
accrue interest.

Section 2.09.  Treasury 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 an Affiliate of the Company, 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 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 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 and deliver them 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), unless the Company directs cancelled Senior
Notes to be returned to it.  Certification of the destruction of all cancelled
Senior Notes shall be delivered to the Company for all certificates so
destroyed.  The Company may not issue new Senior Notes to replace Senior Notes
that it has redeemed, paid or delivered to the Trustee for cancellation.

Section 2.12.  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, which date shall be at the earliest
practicable date but in all events at least five Business Days prior to the
payment date, in each case at the rate provided in the Senior Notes and in
Section 4.01 hereof. The Company shall fix or cause to be fixed each such
special record date and payment date, provided that the Company shall fix or
cause to be fixed 

                                      32
<PAGE>
 
each such special record date as early as practicable prior to the payment date,
and the Company shall mail or cause to be mailed as early as practicable to each
holder a notice that states the special record date, the related payment date
and the amount of defaulted interest to be paid.

Section 2.13.  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 (S) 316(c).

Section 2.14.  CUSIP Number.

          The Company in issuing the Senior Notes may use a "CUSIP" number and,
if it does so, the Trustee shall use the CUSIP number in notices of redemption
or exchange as a convenience to holders; provided that any such notice may state
that no representation is made as to the correctness or accuracy of the CUSIP
number printed in the notice or on the Senior Notes and that reliance may be
placed only on the other identification numbers printed on the Senior Notes. The
Company will promptly notify the Trustee of any change in the CUSIP number.

                                   ARTICLE 3
                      REDEMPTION AND CERTAIN REPURCHASES

Section 3.01.  Notices to Trustee.

          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 (unless a shorter period is acceptable to the Trustee) 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 Notes to Be Redeemed.

          If less than all of the Senior Notes are to be redeemed at any time,
except as provided in Section 3.09, the Trustee shall select the Senior Notes to
be redeemed or purchased 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 (and
in such manner as complies with applicable legal and stock exchange
requirements, if any), provided that no Senior Notes with a principal amount of
$1,000 or less shall be redeemed or purchased in part.  A new Senior Note in
principal amount equal to the unredeemed or unpurchased portion shall be issued
in the name of the holder thereof upon cancellation of the original Note.  On
and after the redemption or purchase date, interest shall cease to accrue on the
Senior Notes or portions of them called for redemption or purchase.  In the
event of partial redemption by lot, the particular Senior Notes to be redeemed
shall be selected, unless otherwise provided 

                                      33
<PAGE>
 
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 Note selected for partial
redemption, the principal amount thereof to be redeemed.  Senior Notes and
portions of them 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 (provided that in the
event of a redemption pursuant to Section 3.07(b) hereof arising out of a sale
of the Company's Capital Stock (other than Disqualified Stock) to a Strategic
Equity Investor, such notice shall not be mailed prior to the consummation of
such sale).

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

          (a)  the redemption date;

          (b)  the redemption price;

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

          (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 (or portions thereof) 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

          (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 (unless, except as
set forth above, a shorter period is acceptable to the Trustee) prior to the

                                      34
<PAGE>
 
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 due and payable on the
redemption date at the redemption price stated in such notice.  A notice of
redemption may not be conditional.


Section 3.05.  Deposit of Redemption Price.

          On or prior to the redemption date, the Company shall deposit with the
Trustee or with the Paying Agent (or, if the Company or a Subsidiary is the
Paying Agent, shall segregate and hold in trust) immediately available funds
sufficient to pay the redemption price of and accrued interest, if any, on all
Senior Notes to be redeemed on that date. The Trustee or the Paying Agent shall
promptly return to the Company any funds deposited with the Trustee or the
Paying Agent by the Company in excess of the amounts necessary to pay the
redemption price of, and accrued interest, if any, on, 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
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 shall be
paid to the Person in whose name such Note was registered at the close of
business on such record date. If any 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
redemption price, from the redemption date until such redemption price 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 the Trustee shall authenticate for the holder of the Senior
Notes at the expense of the Company a new Senior Note equal in principal amount
to the unredeemed portion of the Senior Note surrendered.

Section 3.07.  Optional Redemption.

          (a)  Except as set forth in Section 3.07(b) below, the Senior Notes
will not be redeemable at the Company's option prior to November 1, 2002.
Thereafter, the Senior Notes will be subject to redemption at the option of the
Company, in whole or in part, upon not less than 30 nor more than 60 days'
notice to the holders, at the redemption prices (expressed as percentages of
principal amount) set forth below plus accrued and unpaid interest and
Liquidated Damages, if any, thereon to the applicable redemption date, if
redeemed during the twelve-month period beginning on November 1 of the years
indicated below:

     (b)  Notwithstanding the provisions of Section 3.07(a) above, in the
event of the sale by the Company prior to November 1, 2000 of its Capital Stock
(other than Disqualified Stock) (i) to a Strategic Investor in a single
transaction or series of related transactions for an aggregate purchase price
equal to or exceeding $50.0 million or (ii) in one or more Public Offerings, up
to a maximum of 25% of the aggregate principal amount of the Senior Notes
originally issued shall, at the option of the Company, be redeemable from the
net cash proceeds of such sale or sales to such Strategic Investor (but only to
the extent such proceeds consist of cash or readily marketable cash equivalents
received in respect of the Capital Stock, other than Disqualified Stock, so
sold) at a redemption price equal to 108.875% of the principal amount thereof
plus accrued and unpaid interest and Liquidated Damages, if any, thereon to the
redemption date, provided that at least 75% of the aggregate principal amount of
the Senior Notes originally issued remains outstanding immediately after the
occurrence of such redemption and that such redemption occurs within 90 days of
the date of the closing of such sale.

     (c)  Any redemption pursuant to this Section 3.07 shall be made pursuant to
the provisions of Sections 3.01 through 3.06 hereof.

Section 3.08.  Mandatory Redemption.

          Except as set forth under Sections 3.09 and 4.15 hereof, the Company
shall not be required to make mandatory redemption or sinking fund payments with
respect to the Senior Notes.

Section 3.09.  Offer to Purchase With Excess Asset Sale Proceeds.

          If at any time the cumulative amount of Excess Proceeds that have not
been applied in accordance with this Section 3.09 exceeds $5.0 million, the
Company shall, within 30 days thereafter, make an offer to all holders of Senior
Notes and Pari Passu Notes (an "Excess Proceeds Offer"), to purchase the maximum
principal amount of Senior Notes and Pari Passu Notes that may be purchased out
of such Excess Proceeds, at an offer price in cash in an amount equal to 100% of
the outstanding principal amount of the Senior Notes and 100% of the outstanding
principal amount or accreted value, as applicable, of the Pari Passu Notes, plus
accrued and unpaid interest and Liquidated Damages thereon, if any, to the date
fixed for the closing of such offer, in accordance with the procedures specified
below.

          The Excess Proceeds Offer shall remain open for a period of 20
Business Days following its commencement and no longer, except to the extent
that a longer period is required by applicable law (the "Offer Period").  No
later than five Business Days after the termination of the Offer Period (the
"Purchase Date"), the Company shall purchase the maximum accreted value or
principal amount, as the case may be, of Senior Notes and Pari Passu Notes that
may be purchased with such Excess Proceeds (on a pro rata basis if Senior Notes
and Pari Passu Notes tendered is in excess of the Excess Proceeds) (which
maximum principal amount of Senior Notes shall be the "Offer Amount") or, if
less than the Offer 

                                      36
<PAGE>
 
Amount has been tendered, all Senior Notes and Pari Passu Notes tendered in
response to the Excess Proceeds Offer, subject to the provisions of Section 4.10
hereof.

          If the Purchase Date is on or after an interest record date and on or
before the related interest payment date, any accrued interest on the Senior
Notes shall be paid to the Person in whose name a Senior Note is registered at
the close of business on such record date, and no additional interest shall be
payable to holders who tender Senior Notes pursuant to the Excess Proceeds Offer
on the portion of the tendered Senior Notes purchased pursuant to the Excess
Proceeds Offer.

          Upon the commencement of any Excess Proceeds Offer, the Company shall
send, by first class mail, a notice to the Trustee and each of the holders of
the Senior Notes, with a copy to the Trustee.  The notice shall contain all
instructions and materials necessary to enable such holders to tender Senior
Notes pursuant to the Excess Proceeds Offer.  The Excess Proceeds Offer shall be
made to all holders.  The notice, which shall govern the terms of the Excess
Proceeds Offer, shall state:

          (a)  that the Excess Proceeds Offer is being made pursuant to Sections
     3.09 and 4.10 hereof and the length of time the Excess Proceeds Offer shall
     remain open;

          (b)  the Offer Amount, the purchase price and the Purchase Date;

          (c)  that any Senior Note or portion thereof not tendered or accepted
     for payment shall continue to accrue interest;

          (d)  that any Senior Note or portion thereof accepted for payment
     pursuant to the Excess Proceeds Offer shall cease to accrue interest after
     the Purchase Date;

          (e)  that holders electing to have a Senior Note or portion thereof
     purchased pursuant to any Excess Proceeds Offer shall be required to
     surrender the Senior Note, with the form entitled "Option of Holder to
     Elect Purchase" on the reverse of the Senior Note completed, to the
     Company, a depositary, if appointed by the Company, or a Paying Agent at
     the address specified in the notice at least three Business Days before the
     Purchase Date;

          (f)  that holders shall be entitled to withdraw their election if the
     Company, depositary or 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 or portion thereof the holder delivered for
     purchase and a statement that such holder is withdrawing his election to
     have the Senior Note or portion thereof purchased;

          (g)  that, if the aggregate principal amount, and/or the aggregate
     accreted value as the case may be, of Senior Notes and Pari Passu Notes
     tendered by holders of such notes exceeds the Offer Amount, the Trustee
     shall select the Senior Notes to be purchased on a pro rata basis above
     (with such adjustments as may be deemed appropriate by the Trustee so that
     only Senior Notes in denominations of $1,000, or integral multiples
     thereof, shall be purchased); and

          (h)  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).

                                      37
<PAGE>
 
          On or before the Purchase Date, the Company shall, to the extent
lawful, accept for payment, on a pro rata basis (as described above) to the
extent necessary, the Offer Amount of Senior Notes, Parri Passu Notes or
portions thereof tendered pursuant to the Excess Proceeds Offer, or if less than
the Offer Amount has been tendered, all Senior Notes, Parri Passu Notes or
portions thereof tendered, and deliver to the Trustee an Officers' Certificate
stating that such Senior Notes, Parri Passu Notes or portions thereof were
accepted for payment by the Company in accordance with the terms of this Section
3.09.  The Company or 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 Note
or portion thereof tendered by such holder and accepted by the Company for
purchase, and the Company shall promptly issue a new Senior Note, and the
Trustee shall authenticate and mail or deliver such new Senior Note to such
holder equal in principal amount 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 Excess Proceeds Offer on the Purchase Date.  In the
event that the aggregate amount of Excess Proceeds exceeds the aggregate
principal amount or accreted value, as the case may be, of Senior Notes, Pari
Passu Notes or portions thereof surrendered by holders of such notes pursuant to
an Excess Proceeds Offer, the Company may use the remaining Excess Proceeds for
general purposes.  Upon completion of an Excess Proceeds Offer, the amount of
Excess Proceeds shall be deemed to be reset at zero.

          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.  No repurchase of Senior Notes under this
Section 3.9 shall be deemed to be a redemption of Senior Notes.

Section 4.01.  Payment of Notes.

          The Company shall pay or cause to be paid the principal of, premium,
if any, and interest, on the Senior Notes on the dates and in the manner
provided in the Senior Notes and this Indenture. Principal, premium, if any, and
interest shall be considered paid on the date due if the Paying Agent, if other
than the Company, holds as of the due date money deposited by, or on behalf of,
the Company in immediately available funds and designated for and sufficient to
pay all principal, premium, if any, and interest then due. The Company shall pay
all Liquidated Damages, if any, in the same manner on the dates and in the
amounts set forth in the Note Registration Rights Agreement.

          The Company shall pay interest (including post-petition interest in
any proceeding under any Bankruptcy Law) on overdue principal at the rate equal
to the then applicable interest rate on the Senior Notes to the extent lawful
until such overdue principal is paid; it shall pay interest (including post-
petition interest in any proceeding under any Bankruptcy Law) on overdue
installments of interest (without regard to any applicable grace period) at the
same rate to the extent lawful until such overdue installments of interest are
paid.

          The term "Bankruptcy Law" means title 11, U.S. Code or any similar
federal or state law for the relief of debtors.

Section 4.02.  Maintenance of Office or Agency.

          The Company shall maintain an office or agency (which may be an office
of the Trustee or an affiliate of the Trustee, Registrar or co-registrar) where
Senior Notes may be surrendered for registration of transfer or exchange and
where notices and demands to or upon the Company in respect of the Senior Notes
and this Indenture may be served. The Company shall give prompt written notice
to the Trustee of the location, and any change in the location, of such office
or agency. If at any time the Company shall fail to maintain any such required
office or agency or shall fail to furnish the Trustee with the address thereof,
such presentations, surrenders, notices and demands may be made or served at the
Corporate Trust Office of the Trustee.

          The Company may also from time to time designate one or more other
offices or agencies where the Senior Notes may be presented or surrendered for
any or all such purposes and may from time to time rescind such designations;
provided, however, that no such designation or rescission shall in any manner
relieve the Company of its obligation to maintain an office or agency for such
purposes. The Company shall give prompt written notice to the Trustee of any
such designation or rescission and of any change in the location of any such
other office or agency.

          The Company hereby designates the Corporate Trust Office of the
Trustee as one such office or agency of the Company in accordance with Section
2.03 hereof.


Section 4.03.  Reports.

          (a)  So long as any of the Senior Notes remain outstanding, the
Company shall cause copies of all quarterly and annual financial reports and of
the information, documents, and other reports (or copies of such portions of any
of the foregoing as the Securities and Exchange Commission (the "Commission")
may by rules and regulations prescribe) which the Company is required to file
with the Commission pursuant to Section 13(a) or 15(d) of the Exchange Act ("SEC
Reports") to be filed with the Trustee within 15 days of filing with the
Commission. If the Company is not subject to the requirements of Section 13(a)
or 15(d) of the Exchange Act or shall cease to be required by the Commission to
file SEC Reports pursuant to the Exchange Act, the Company shall nevertheless
continue to cause SEC Reports, comparable to those which it would be required to
file pursuant to Section 13(a) or 15(d) of the Exchange Act if it were subject
to the requirements of either such section, to be so filed with the Commission
(unless the Commission will not accept such a filing) and with the Trustee
within the same time periods as would have applied (including under the
preceding sentence) had the Company been subject to the requirements of Section
13(a) or 15(d) of the Exchange Act. Whether or not required by the Exchange Act
to file SEC Reports with the Commission, so long as any Senior Notes are
outstanding, the Company shall furnish copies of the SEC Reports to the holders
of Senior Notes at the time the Company is required to file the same with the
Trustee and make such information available to investors who request it in
writing. In addition, the Company shall, for so long as any Senior Notes remain
outstanding, furnish to the holders and to securities analysts and prospective
investors, upon their request, the information required to be delivered pursuant
to Rule 144(d)(4) under the Securities Act. The Company shall also comply with
the provisions of TIA (S) 314(a).

          (b)  The Company shall provide the Trustee with a sufficient number of
copies of all SEC Reports that the Trustee may be required to deliver to the
holders of the Senior Notes under this Section 4.03.

          (a)  The Company shall deliver to the Trustee, within 90 days after
the end of each fiscal year of the Company, an Officers' Certificate stating
that (i) a review of the activities of the Company and its Subsidiaries during
the preceding fiscal year has been made under the supervision of the signing
Officers with a view to determining whether the Company has (x) kept, observed,
performed and fulfilled, and (y) caused each of its Subsidiaries to keep,
observe, perform and fulfill, its obligations under this Indenture, and (ii) as
to each such Officer signing such certificate, that to the best of his or her
knowledge (A) the Company has kept, observed, performed and fulfilled, and has
caused each of its Subsidiaries to keep, observe, perform and fulfill, each and
every covenant contained in this Indenture and is not in default in the
performance or observance of any of the terms, provisions and conditions of this
Indenture to be performed or observed by it (or, if a Default or Event of
Default shall have occurred, describing all such Defaults or Events of Default
of which he or she may have knowledge and what action each is taking or proposes
to take with respect thereto) and (B) no event has occurred and remains in
existence by reason of which payments on account of the principal of or
interest, if any, on the Senior Notes is prohibited or if such event has
occurred, a description of the event and what action each is taking or proposes

          (b)  So long as not contrary to the then current recommendations of
the American Institute of Certified Public Accountants, the year-end financial
statements delivered pursuant to Section 4.03 above shall be accompanied by a
written statement of the Company's independent public accountants (who shall be
a firm of established national reputation) that in making the examination
necessary for certification of such financial statements, nothing has come to
their attention which would lead them to believe that the Company has violated
any provisions of Article 4 or Article 5 of this Indenture or, if any such
violation has occurred, specifying the nature and period of existence thereof,
it being understood that such accountants shall not be liable directly or
indirectly to any Person for any failure to obtain knowledge of any such
violation.

          (c)  The Company shall, so long as any of the Senior Notes are
outstanding, deliver to the Trustee, forthwith upon any Officer becoming aware
of any Default or Event of Default, an Officers' Certificate specifying such
Default, Event of Default or default and what action the Company is taking or
proposes to take with respect thereto.

          (d)  The Company shall deliver to the Trustee an Officers' Certificate

to the holders of the Senior Notes.

     The Company covenants (to the extent that it may lawfully do so) that it
shall not at any time insist upon, plead, or in any manner whatsoever claim or
take the benefit or advantage of, any stay, extension or usury law wherever
enacted, now or at any time hereafter in force, that may affect the covenants or
the performance of this Indenture; and the Company (to the extent that it may
lawfully do so) hereby expressly waives all benefit or advantage of any such
law, and covenants that it shall not, by resort to any such law, hinder, delay
or impede the execution of any power herein granted to the Trustee, but shall
suffer and permit the execution of every such power as though no such law has
been enacted.


Section 4.07.  Restricted Payments.

     (a)  The Company shall not, and shall not permit any of its Subsidiaries
to, directly or indirectly:

          (i)   declare or pay any dividend or make any distribution on account
     of any Equity Interests of the Company or any of its Subsidiaries other

     Subsidiary;

          (ii)  purchase, redeem, defease, retire or otherwise acquire for value

     in accordance with the mandatory redemption or repayment provisions set
     forth in the original documentation governing such Indebtedness; or

          (iv)  make any Restricted Investment (all such payments and other
     actions set forth in clauses (i) through (iv) above being collectively
     referred to as "Restricted Payments"), unless, at the time of such
     Restricted Payment:

                (1) no Default or Event of Default has occurred and is
          continuing or would occur as a consequence thereof;

                (2) after giving effect to such Restricted Payment on a pro
          forma basis as if such Restricted Payment had been made at the
          beginning of the applicable four-quarter period, the Company could
          incur at least $1.00 of additional Indebtedness pursuant to the
          Consolidated Cash Flow Leverage Ratio test set forth in Section
          4.09(a) hereof; and

                (3) such Restricted Payment, together with the aggregate of all
          other Restricted Payments made by the Company and its Subsidiaries
          after the Issue Date (including any Restricted Payments made pursuant
          to clauses (i), (v) and (vi) of Section 4.07(b)), is less than the sum
          of

                (w) 50% of the Consolidated Net Income of the Company for the
          period (taken as one accounting period) from June 30, 1996 to the end
          of the Company's most recently ended fiscal quarter for which internal
          financial statements are available at the time of such Restricted
          Payment (or, if such Consolidated Net Income for such period is a
          deficit, less 100% of such deficit), plus

                (x) 100% of the aggregate net cash proceeds received by the
          Company from the issue or sale of Equity Interests of the Company or

          convertible debt securities) sold to a Subsidiary of the Company and
          other than Disqualified Stock or debt securities that have been
          converted into Disqualified Stock) after June 30, 1996 (other than any
          such Equity Interests, the proceeds of which were used as set forth in
          clause (b)(ii) below), plus

                (y) 100% of the sum of, without duplication, (1) aggregate
          dividends or distributions received by the Company or any Subsidiary
          from any Joint Venture (other than dividends or distributions to pay
          any obligations of such Joint Venture to Persons other than the
          Company or any Subsidiary, such as income taxes), with non-cash
          distributions to be valued at the lower of book value or fair market
          value as determined by the Board of Directors, (2) the amount of the
          principal and interest payments received since the Issue Date by the
          Company or any Subsidiary from any Joint Venture and (3) the net
          proceeds from the sale of an Investment in a Joint Venture received by
          the Company or any Subsidiary; provided that there is no obligation to
          return any such amounts to the Joint Venture, and excluding any such
          dividend, distribution, interest payment or net proceeds that
          constitutes a return of capital invested pursuant to clause (b)(vi) of
          this Section 4.07, plus

                (z) $10.0 million.

     (b)  The foregoing provisions in Section 4.07(a) shall not prohibit:

          (i)   the payment of any dividend within 60 days after the date of
     declaration thereof, if at such date of declaration such payment would have
     complied with the provisions of this Indenture;

          (ii)  the Retirement of (A) any Equity Interests of the Company or any
     Subsidiary of the Company, (B) Indebtedness of the Company that is

     Company, in exchange for, or out of the proceeds of the substantially
     concurrent sale (other than to a Subsidiary of the Company) of, Equity
     Interests of the Company (other than Disqualified Stock);

          (iii) the Retirement of any Indebtedness of the Company subordinated
     in right of payment to the Senior Notes in exchange for, or out of the
     proceeds of the substantially concurrent incurrence of Indebtedness of the
     Company (other than Indebtedness to a Subsidiary of the Company), but only
     to the extent that such new Indebtedness is permitted under Section 4.09

                                      42
<PAGE>
 
     hereof and (1) is subordinated in right of payment to the Senior Notes at
     least to the same extent as, (2) has a Weighted Average Life to Maturity at
     least as long as, and (3) has no scheduled principal payments due in any
     amount earlier than, any equivalent amount of principal under the
     Indebtedness so Retired;

          (iv)  the Retirement of any Indebtedness of a Subsidiary of the
     Company in exchange for, or out of the proceeds of the substantially
     concurrent incurrence of Indebtedness of the Company or any Subsidiary but
     only to the extent that such incurrence is permitted under Section 4.09
     hereof and only to the extent that such Indebtedness (1) is not secured by
     any assets of the Company or any Subsidiary to a greater extent than the
     Retired Indebtedness was so secured, (2) has a Weighted Average Life to
     Maturity at least as long as the Retired Indebtedness and (3) if such
     Retired Indebtedness was an obligation of the Company, is pari passu or
     subordinated in right of payment to the Senior Notes at least to the same
     extent as the Retired Indebtedness;

          (v)   the Retirement of any Equity Interests of the Company or any
     Subsidiary of the Company held by any member of the Company's (or any of
     its Subsidiaries') management pursuant to any management equity
     subscription agreement or stock option agreement; provided that the
     aggregate price paid for all such repurchased, redeemed, acquired or
     retired Equity Interests shall not exceed $1.0 million in any twelve-month
     period plus the aggregate cash proceeds received by the Company during such
     twelve-month period from any reissuance of Equity Interests by the Company
     to members of management of the Company and its Subsidiaries;

          (vi)  Investments in any Joint Venture; provided that at the time any
     such Investment is made, such Investment shall not cause the aggregate
     amount of Investments at any one time outstanding under this clause (vi) to
     exceed the greater of (x) $25.0 million and (y) 5% of the Total Common
     Equity of the Company; and

          (vii) the payment of cash in lieu of fractional shares (a) payable as
     dividends on Equity Interests of the Company or (b) issuable upon
     conversion of or in exchange for securities convertible into or
     exchangeable for Equity Interests of the Company or (c) issuable as a
     result of a corporate reorganization, provided that, in the case of (a) and
     (b), the issuance of such Equity Interests or securities and, in the case
     of (c), such corporate reorganization, is permitted under the terms of this
     Indenture.

provided, however, that at the time of, and after giving effect to, any
Restricted Payment permitted under clauses (i), (ii), (iii), (iv), (v) and (vi),
no Default or Event of Default shall have occurred and be continuing.

     (c)  A Permitted Investment that ceases to be a Permitted Investment
pursuant to the definition thereof set forth in Section 1.01 hereof, shall
become a Restricted Investment, deemed to have been made on the date that it
ceases to be a Permitted Investment.

     (d)  The Board of Directors may designate any Subsidiary to be an
Unrestricted Subsidiary if such designation would not cause a Default or an
Event of Default pursuant to Article 6 hereof.  For purposes of making such
determination, all outstanding Investments by the Company and its Subsidiaries
(except to the extent repaid in cash) in such Subsidiary so designated shall be
deemed to be Restricted 

                                      43
<PAGE>
 
Payments at the time of such designation and shall reduce the amount available
for Restricted Payments under paragraph (a) of this Section 4.07. All such
outstanding Investments will be deemed to constitute Investments in an amount
equal to the greatest of (x) the net book value of such Investments at the time
of such designation, (y) the fair market value of such Investments at the time
of such designation and (z) the original fair market value of such Investments
at the time they were made. Such designation will only be permitted if such
Restricted Payment would be permitted at such time.

     (e)  The Board of Directors of the Company may at any time designate any
Unrestricted Subsidiary to be a Subsidiary; provided that such designation shall
be deemed to be an incurrence of Indebtedness by a Subsidiary of the Company of
any outstanding Indebtedness of such Unrestricted Subsidiary and such
designation shall only be permitted if (i) such Indebtedness is permitted under
Section 4.09 hereof and (ii) no Default or Event of Default pursuant to Article
6 hereof would be in existence following such designation.

     (f)  Not later than the date of making any Restricted Payment, the Company
shall deliver to the Trustee an Officers' Certificate stating that such
Restricted Payment is permitted and setting forth the basis upon which the
calculations required by this Section 4.07 were computed, which calculations may
be based upon the Company's latest available financial statements.


Section 4.08.  Dividend and Other Payment Restrictions Affecting Subsidiaries.

     The Company shall not, and shall not permit any of its Subsidiaries to,
directly or indirectly, create or otherwise cause to become effective any
consensual encumbrance or restriction on the ability of any Subsidiary to:

          (i)   pay dividends or make any other distributions to the Company or
     any of its Subsidiaries on its Capital Stock or with respect to any other
     interest or participation in, or measured by, its prof its, or pay any
     Indebtedness owed to the Company or any of its Subsidiaries;

          (ii)  make loans or advances to the Company or any of its
     Subsidiaries; or

          (iii) transfer any of its properties or assets to the Company or any
     of its Subsidiaries;

except for such encumbrances or restrictions existing as of the Issue Date or
under or by reason of:

          (a)   Existing Indebtedness;

          (b)   applicable law;

          (c)   any instrument governing Acquired Debt as in effect at the time
     of acquisition (except to the extent such Indebtedness was incurred in
     connection with, or in contemplation of, such acquisition), which
     encumbrance or restriction is not applicable to any Person, or the
     properties or assets of any Person, other than the Person, or the property
     or assets of the Person, so acquired;

                                      44
<PAGE>
 
          (d)  by reason of customary non-assignment provisions in leases
     entered into in the ordinary course of business and consistent with past
     practices;

          (e)  Indebtedness in respect of a Permitted Refinancing, provided that
     the restrictions contained in the agreements governing such Refinancing
     Indebtedness are not materially more restrictive than those contained in
     the agreements governing the Indebtedness being refinanced;

          (f)  with respect to clause (iii) above, purchase money obligations
     for property acquired in the ordinary course of business, Vendor
     Indebtedness incurred in connection with the purchase or lease of
     Telecommunications Related Assets or performance bonds or similar security
     for performance which liens securing such obligations do not cover any
     asset other than the asset acquired or, in the case of performance bonds or
     similar security for performance, the assets associated with the Company's
     performance;

          (g)  Indebtedness incurred under Section 4.09(b)(i) hereof;

          (h)  this Indenture and the Senior Notes or future Indebtedness with
     substantially similar restrictions, if any, to the Senior Notes; or

          (i) in the case of clauses (a), (c), (e), (g) and (h) above, any
          amendments, modifications, restatements, renewals, increases,
          supplements, refundings, replacements or refinancings thereof;
          provided that such amendments, modifications, restatements, renewals,
          increases, supplements, refundings, replacements or refinancings are
          not materially more restrictive with respect to such dividend and
          other payment restrictions than those contained in such instruments as
          in effect on the date of their incurrence or, if later, the Issue
          Date.

Section 4.09.  Incurrence of Indebtedness and Issuance of Disqualified Stock.

     (a)  The Company and its Subsidiaries shall not, directly or indirectly,
(i) create, incur, issue, assume, guarantee or otherwise become directly or
indirectly liable for the payment of (collectively, "incur" and, correlatively,
"incurred" and "incurrence") any Indebtedness (including, without limitation,
Acquired Debt) or (ii) issue any Disqualified Stock; provided, however, that the
Company and/or any of its Subsidiaries may incur Indebtedness (including,
without limitation, Acquired Debt) or issue shares of Disqualified Stock if,
after giving effect to the incurrence of such Indebtedness or the issuance of
such Disqualified Stock, the Consolidated Cash Flow Leverage Ratio for the
Company's most recently ended four full fiscal quarters for which internal
financial statements are available immediately preceding the date of such
incurrence or issuance (x) does not exceed 5.5 to 1 if such incurrence or
issuance occurs on or prior to June 1, 1999 and (y) does not exceed 5.0 to 1 if
such occurrence or issuance occurs after June 1, 1999, in each case, determined
on a pro forma basis (including a pro forma application of the net proceeds
therefrom), as if the additional Indebtedness had been incurred, or the
Disqualified Stock had been issued, as the case may be, at the beginning of such
four-quarter period. If the Company incurs any Indebtedness or issues or redeems
any Preferred Stock subsequent to the commencement of the period for which such
ratio is being calculated but prior to the event for which the calculation of
the ratio is made, then the ratio will be calculated giving pro forma effect to
any such incurrence of Indebtedness, or such issuance or redemption of Preferred
Stock, as if the same had occurred at the beginning of the applicable period. In
making such calculation on a pro forma basis, interest attributable to
Indebtedness 

                                      45
<PAGE>
 
bearing a floating interest rate shall be computed as if the rate in effect on
the date of computation had been the applicable rate for the entire period.

     (b)  The foregoing limitation in Section 4.09(a) shall not apply to (with
each exception to be given independent effect):

          (i)   the incurrence by the Company and/or any of its Subsidiaries of
          Indebtedness under the Credit Facility in an aggregate principal
          amount at any one time outstanding (with letters of credit being
          deemed to have a principal amount equal to the maximum potential
          liability of the Company and/or any of its Subsidiaries thereunder)
          not to exceed $75.0 million in the aggregate at any one time
          outstanding, less the aggregate amount of all Net Proceeds of Asset
          Sales applied to permanently reduce the commitments with respect to
          such Indebtedness pursuant to Section 4.10 hereof;

          (ii)  the incurrence by the Company and/or any of its Subsidiaries of
          Vendor Indebtedness, provided that the aggregate amount of such Vendor
          Indebtedness incurred 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 Indebtedness was extended for the purchase of tangible
          physical assets and was so financed by the vendor thereof or an
          affiliate of such vendor);

          (iii) the incurrence by the Company and/or any of its Subsidiaries of
          the Existing Indebtedness, including the Existing Senior Notes;

          (iv)  the incurrence by the Company and/or any of its Subsidiaries of
          Indebtedness in an aggregate amount not to exceed $25.0 million at any
          one time outstanding;

          (v)   the incurrence by the Company of Indebtedness, but only to the
          extent that such Indebtedness is expressly subordinate to the payment
          in full of all Obligations with respect to the Senior Notes and has a
          final maturity no earlier than, and a Weighted Average Life to
          Maturity equal to or greater than, the final maturity and Weighted
          Average Life to Maturity, respectively, of the Senior Notes, in an
          aggregate principal amount not to exceed 2.0 times the net cash
          proceeds received by the Company after June 30, 1996 from the issuance
          and sale of Equity Interests of the Company (that are not Disqualified
          Stock) plus the fair market value of Equity Interests (other than
          Disqualified Stock) issued after June 30, 1996 in connection with any
          acquisition of any Telecommunications Business;

          (vi)  the incurrence (a "Permitted Refinancing") by the Company and/or
          any of its Subsidiaries of Indebtedness issued in exchange for, or the
          proceeds of which are used to refinance, replace, refund or defease
          ("Refinance" and correlatively, "Refinanced" and "Refinancing")
          Indebtedness, other than Indebtedness incurred pursuant to clause (i)
          above, but only to the extent that:

                    (1) the net proceeds of such Refinancing Indebtedness shall
                not exceed the principal amount of and premium, if any, and
                accrued interest on the Indebtedness so Refinanced (or if such
                Indebtedness was issued at an original issue discount, the
                original issue price plus amortization of the original issue
                discount at the time of the repayment of

                                      46
<PAGE>
 
                such Indebtedness) plus the fees, expenses and costs of such
                Refinancing and reasonable prepayment premiums, if any, in
                connection therewith;

                    (2) the Refinancing Indebtedness shall have a final maturity
                no earlier than, and a Weighted Average Life to Maturity equal
                to or greater than, the final maturity and Weighted Average Life
                to Maturity of the Indebtedness being Refinanced; and

                    (3) if the Indebtedness being Refinanced is subordinated in
                right of payment to the Senior Notes, the Refinancing
                Indebtedness shall be subordinated in right of payment to the
                Senior Notes on terms at least as favorable to the holders of
                Senior Notes as those contained in the documentation governing
                the Indebtedness being so Refinanced;

          (vii)  the incurrence by the Company or any of its Subsidiaries of
          intercompany Indebtedness between or among the Company and any of its
          Subsidiaries; and

          (viii) the incurrence by the Company or any of its Subsidiaries of
          Hedging Obligations that are incurred for the purpose of fixing or
          hedging interest rate or foreign currency risk with respect to any
          floating rate Indebtedness that is permitted by the terms of this
          Indenture to be outstanding.

          For purposes of determining compliance with this Section 4.09, in the
event that an item of Indebtedness, Disqualified Stock or Preferred Stock meets
the criteria of more than one of the categories described in clauses (i) through
(viii) above or is entitled to be incurred pursuant to Section 4.09(a), the
Company shall, in its sole discretion, classify such item in any manner that
complies with this Section and such item shall be treated as having been
incurred pursuant to only one of such clauses or pursuant to Section 4.09(a).
Accrual of interest or dividends, the accretion of accreted value or liquidation
preference and the payment of interest or dividends in the form of additional
Indebtedness, Common Stock or Preferred Stock shall not be deemed to be an
incurrence of Indebtedness for purposes of this Section.

Section 4.10.  Asset Sales.

          (a)  The Company shall not, and shall not permit any of its
Subsidiaries to, whether in a single transaction or a series of related

of related transactions occurring within any twelve-month period, such assets or
securities

          (x)  have a Fair Market Value in excess of $2.0 million or

          (y)  are sold or otherwise disposed of for net proceeds in excess of
          $2.0 million (each of the foregoing, an "Asset Sale"), unless:

               (a)  no Default or Event of Default exists or would occur as a
          result thereof;

               (b)  the Company, or such Subsidiary, as the case may be,
          receives consideration at the time of such Asset Sale at least equal
          to the Fair Market Value (evidenced by a resolution of the Board of
          Directors of the Company set forth in an Officers' Certificate
          delivered to the Trustee), of the assets or securities issued or sold
          or otherwise disposed of; and

               (c)  at least 85% of the consideration therefor received by the
          Company or such Subsidiary is in the form of cash, provided, however,
          that (A) the amount of (x) any liabilities (as shown on the Company's

          thereto), of the Company or any Subsidiary of the Company (other than

          that are assumed by the transferee of any such assets and (y) any
          notes, obligations or other securities received by the Company or any
          such Subsidiary from such transferee that are immediately converted by
          the Company or such Subsidiary into cash, shall be deemed to be cash
          (to the extent of the cash received in the case of subclause (y)) for
          purposes of this clause (c); and (B) an amount equal to the Fair
          Market Value (determined as set forth in clause (b) above) of (1)
          Telecommunications Related Assets received by the Company or any such
          Subsidiary from the transferee that will be used by the Company or any
          such Subsidiary in the operation of a Telecommunications Business in
          the United States and (2) the Voting Stock of any Person engaged in
          the Telecommunications Business in the United States received by the
          Company or any such Subsidiary (provided that such Voting Stock is
          converted to cash within 270 days or such Person concurrently becomes
          or is a Subsidiary of the Company) shall be deemed to be cash for
          purposes of this clause (c).

          The foregoing provisions shall not apply to a sale, lease, conveyance
or other disposition of all or substantially all of the assets of the Company,
which shall be governed by Article 5 hereof.

Sale, the Company (or such Subsidiary, as the case may be) may apply the Net
Proceeds from such Asset Sale to (i) permanently reduce the amounts permitted to
be borrowed by the Company under the terms of any of its Senior Indebtedness or
(ii) the purchase of Telecommunications Related Assets or Voting Stock of any
Person engaged in the Telecommunications Business in the United States (provided
that such Person concurrently becomes a Subsidiary of the Company). Any Net
Proceeds from any Asset Sales that are not so applied or invested as provided in
the preceding sentence, shall constitute "Excess Proceeds." When the aggregate
amount of Excess Proceeds exceeds $5.0 million, the Company shall be required to
make an Excess Proceeds Offer in accordance with the terms of Section 3.09

any contract, agreement, understanding, loan, advance or guarantee with, or for
the benefit of, any Affiliate (each of the foregoing, an "Affiliate

have been obtained in a comparable transaction by the Company or such Subsidiary
with an unrelated Person; (ii) such Affiliate Transaction is approved by a
majority of the disinterested directors on the Board of Directors of the
Company; and (iii) the Company delivers to the Trustee, with respect to any

an Officers' Certificate certifying that such Affiliate Transaction complies
with clauses (i) and (ii) above; provided that (a) transactions pursuant to any

time outstanding, shall not be deemed Affiliate Transactions.


Section 4.12.  Liens.

          The Company shall not, and shall not permit any of its Subsidiaries
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

          The Company shall not, and shall not permit any of its Subsidiaries
to, directly or indirectly, enter into, assume, Guarantee or otherwise become
liable with respect to any Sale and Leaseback Transaction, provided that the

received by the Company or such Subsidiary from such transaction are applied in
accordance with Section 4.10 hereof.


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

the 

                                      49
<PAGE>
 
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, however, 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 of the
Company 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 and Liquidated
Damages, if any, thereon, to the date of purchase (the "Change of Control
Payment"), provided that if the date of purchase is on or after an interest
record date and on or before the related interest payment date, any accrued
interest shall be paid to the Person in whose name a Senior Note is registered
at the close of business on such record date, and no additional interest shall
be paid or payable to holders who tender Senior Notes pursuant to the Change of
Control Offer. Within thirty (30) days following any Change of Control, the
Company shall mail a notice to the Trustee and each holder stating: (1) that the
Change of Control Offer is being made pursuant to this Section 4.15 and that all
Senior Notes or portions thereof tendered will be accepted for payment; (2) the
purchase price and the purchase date, which shall be no earlier than 30 days nor
later than 40 days (unless required by applicable law) from the date such notice
is mailed (the "Change of Control Payment Date"); (3) that any Senior Note or
portion thereof not tendered will continue to accrue interest in accordance with
its terms; (4) that, unless the Company defaults in the payment of the Change of
Control Payment, all Senior Notes or portions thereof accepted for payment
pursuant to the Change of Control Offer shall cease to accrue interest after the
Change of Control Payment Date; (5) that holders electing to have any Senior
Notes or portions thereof 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 or portions thereof delivered for purchase, and a
statement that such holder is withdrawing his election to have such Senior Notes
or portions thereof 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 the Senior Notes or portions thereof in connection with a Change
of Control.

          (b)  On the Change of Control Payment Date, the Company shall, to the
extent lawful, (i) accept for payment Senior Notes or portions thereof tendered
pursuant to the Change of Control Offer, (ii) deposit with the Paying Agent an
amount equal to the Change of Control Payment in respect of all 

                                      50
<PAGE>
 
Senior Notes or portions thereof, and the Trustee shall promptly authenticate
and mail to each holder a new Senior Note equal in principal amount to any
unpurchased portion of the Senior Notes surrendered, 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.

          The Company shall not, and shall not permit any of its Affiliates to,
directly or indirectly, pay or cause to be paid any consideration, whether by
way of interest, fee or otherwise, to any holder of any Senior Notes for or as
an inducement to any consent, waiver or amendment of any of the terms or
provisions of this Indenture or the Senior Notes unless such consideration is
offered to be paid or agreed to be paid to all holders of the Senior Notes that
consent, waive or agree to amend in the time frame set forth in the solicitation
documents relating to such consent, waiver or agreement.

Section 4.18.  Use of Proceeds.

          The Company shall use the gross proceeds from the sale of the Senior
Notes only for the following purposes:

     (i)  to pay the fees and expenses of the issuance of the Senior Notes
including any discount or commission to the Initial Purchasers of the Senior
Notes; and

     (ii) with respect to any funds remaining after application under clause (i)
above, to fund up to 80% of the cost of the acquisition or construction of
Telecommunications Related Assets, or to the repayment of the Existing Senior
Notes.

          Pending application of the proceeds in accordance with clause (ii)
above, the Company shall deposit such proceeds into a segregated account in the
Company's name.  The Company shall deliver to the Trustee an Officer's
Certificate with each annual compliance certificate certifying that the amounts
in such account were applied in accordance with this Section 4.18.

Company is the surviving entity), or sell, assign, transfer, lease, convey or
otherwise dispose of all or substantially all of its properties or assets in one
or more related transactions to another corporation, Person or entity unless:

          (i)   the Company is the surviving entity or the entity or Person
     formed by or surviving any such consolidation or merger (if other than the
     Company) or to which such sale, assignment, transfer, lease, conveyance or
     other disposition has been made is a corporation organized or existing
     under the laws of the United States, any state thereof or the District of
     Columbia;

          (ii)  the entity or Person formed by or surviving any such
     consolidation or merger (if other than the Company) or the entity or Person
     to which such sale, assignment, transfer, lease, conveyance or other
     disposition has been made assumes all the obligations of the Company under

     or surviving any such consolidation or merger, or to which such sale,
     assignment, transfer, lease, conveyance or other disposition has been made,
     at the time of such transaction after giving pro forma effect thereto as if
     such transaction had occurred at the beginning of the applicable fiscal
     quarter (including any Indebtedness incurred or anticipated to be incurred
     in connection with or in respect of such transaction or series of
     transactions), either (A) could incur at least $1.00 of additional
     Indebtedness pursuant to the Consolidated Cash Flow Leverage Ratio test
     described under Section 4.09 hereof or (B) would have (x) Total Market
     Capitalization of at least $1.0 billion and (y) total Indebtedness in an
     amount no greater than 30% of its Total Market Capitalization; and

          (v)   such transaction would not result in the loss, material
     impairment or adverse modification or amendment of any authorization or
     license of the Company or its Subsidiaries that would have a material
     adverse effect on the business or operations of the Company and its
     Subsidiaries taken as a whole.


Section 5.02.Successor Corporation Substituted.

     Upon any consolidation or merger, or any sale, lease, conveyance or other
disposition of all or substantially all of the assets of the Company in
accordance with Section 5.01 hereof, the successor corporation formed by such
consolidation or into or with which the Company is merged or to which such sale,
lease, conveyance or other disposition is made shall succeed to, and be
substituted for (so that from 

                                      52
<PAGE>
 
and after the date of such consolidation, merger, sale, lease, conveyance or
other disposition, the provisions of this Indenture referring to the Company
shall refer instead to the successor corporation and not to the Company), and
may exercise every right and power of the Company under this Indenture with the
same effect as if such successor Person had been named as the Company, herein;
provided, however, that the predecessor Company shall not be relieved from the
obligations to pay the principal of, premium, if any, and interest on the Senior
Notes, except in the case of a sale of all of the Company's assets that meets
the requirements of Section 5.01 hereof.

Section 6.01.  Events of Default.

        Each of the following constitutes an "Event of Default":

     (a)  default for 30 days in the payment when due of interest or Liquidated
          Damages, if any, on the Senior Notes;

     (b)  default in payment when due of principal or premium, if any, on the
          Senior Notes at maturity, upon redemption or otherwise;

          Sections 4.07, 4.09, 4.10, 4.15 or 5.01 hereof;

     (d)  failure by the Company for 30 days after notice from the Trustee or
          the holders of at least 25% in principal amount of the Senior Notes
          then outstanding to comply with its other agreements in this Indenture
          or the Senior Notes;

     (e)  default under any mortgage, indenture or instrument under which there
          may be issued or by which there may be secured or evidenced any
          Indebtedness for money borrowed by the Company or any 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 Issue Date, which default (x) is
          caused by a failure to pay when due principal, premium, if any, or
          interest on such Indebtedness within the grace period provided in such
          Indebtedness (a "Payment Default"), and the principal amount of any
          such Indebtedness, together with the principal amount of any other
          such Indebtedness of the Company or any Significant Subsidiary under
          which there has been a Payment Default or the maturity of which has
          been accelerated as provided in clause (y), aggregates $5.0 million or
          more or (y) results in the acceleration (which acceleration has not
          been rescinded) of such Indebtedness prior to its express maturity and
          the principal amount of any such Indebtedness, together with the
          principal amount of any other such Indebtedness under which there has
          been a Payment Default or the maturity of which has been so
          accelerated, aggregates $5.0 million or more;

     (f)  failure by the Company or any of its Significant Subsidiaries to pay
          final judgments (other than any judgment as to which a reputable
          insurance company has accepted full liability

                                      53
<PAGE>
 
          in writing) aggregating in excess of $5.0 million which judgments are
          not paid, discharged or stayed within 45 days after their entry; and

     (g)  the Company or any of its Significant Subsidiaries pursuant to or
          within the meaning of Bankruptcy Law:
                    
               (A)  commences a voluntary case,

               (B)  consents to the entry of an order for relief against it in
          an involuntary case,

               (C)  consents to the appointment of a Bankruptcy Custodian of it
          or for all or substantially all of its property,

               (D)  makes a general assignment for the benefit of its creditors,
          or

               (E)  admits in writing that it is generally not paying its debts
          (other than debts which are the subject of a bona fide
          dispute) as they become due; or

     (h)  a court of competent jurisdiction enters an order or decree under any
          Bankruptcy Law that;

               (A)  is for relief against the Company or any of its Significant
          Subsidiaries in an involuntary case;

               (B)  appoints a Bankruptcy Custodian of the Company or any of its
          Significant Subsidiaries or for all or substantially all of the
          property of the Company or any of its Significant Subsidiaries; or

               (C)  orders the liquidation of the Company or any of its
          Significant Subsidiaries;

     and the order or decree remains unstayed and in effect for 60 consecutive
     days; provided, however; that if the entry of such order or decree is
     appealed and dismissed on appeal or otherwise has ceased to be in effect,
     then the Event of Default hereunder by reason of the entry of such order or
     decree shall be deemed to have been cured and the related acceleration,
     provided that no other Event of Default has occurred and is continuing,
     shall be deemed rescinded.

     The term "Bankruptcy Custodian" means any receiver, trustee, assignee,
liquidator or similar official under any Bankruptcy Law.


Section 6.02.  Acceleration.

     If any Event of Default occurs and is continuing under this Indenture, 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 such declaration, the principal of, premium, if any, and
accrued and unpaid interest and Liquidated Damages, if any, on the Senior Notes
shall be due and payable immediately.  Notwithstanding the foregoing, in the
case of an Event of Default arising under Sections 6.01(g) or (h) hereof with
respect to the Company or any of its Significant Subsidiaries, the 

                                      54
<PAGE>
 
foregoing amount shall ipso facto become due and payable without further action
or notice. No premium is payable upon acceleration of the Senior Notes except
that in the case of an Event of Default that is the result of an action or
inaction by the Company or any of its Subsidiaries intended to avoid
restrictions on or premiums related to redemptions of the Senior Notes contained
in this Indenture or the Senior Notes, the amount declared due and payable shall
include the premium that would have been applicable on a voluntary prepayment of
the Senior Notes or, if voluntary prepayment is not then permitted, the premium
set forth in this Indenture. Holders of the Senior Notes may not enforce this
Indenture or the Senior Notes except as provided herein.

     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.  If an Event of Default occurs
prior to November 1, 2002 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 on redemption of the Senior Notes prior to such date pursuant to
Section 3.07 hereof, then the premium payable for purposes of this paragraph for
each of the years beginning on November 1st of the years set forth below shall
be as set forth in the following table, expressed as a percentage 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:

          YEAR                                PERCENTAGE
          ----                                ----------

          1997...............................   8.875%
          1998...............................   7.988%
          1999...............................   7.101%
          2000...............................   6.213%
          2001...............................   5.326%
          2002...............................   4.438%

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, interest and Liquidated Damages, if any, on the Senior Notes or to enforce
the performance of any provision of the Senior Notes or this Indenture.

          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 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 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, except a continuing Default or Event of 

                                      55

Default in the payment of interest or Liquidated Damages or premium on, or the
principal of, the Senior Notes. 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. However, the Trustee may refuse to follow any direction that
conflicts with the law or this Indenture that the Trustee, in its sole
discretion, 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.

          No holder of any Senior Note shall have any right to institute any
proceeding with respect to this Indenture or the Senior Notes or for any remedy
thereunder, unless:

     continuing Event of Default;

          (ii)  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;

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

          (iv)  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.

          Otherwise, no holder of any Senior Note shall have any right to
institute any proceeding with respect to this Indenture or the Senior Notes or
for any remedy thereunder, except:

          (x)   a holder of a Senior Note may institute suit for enforcement of
payment of the principal of and premium, if any, or interest on such Senior Note
on or after the respective due dates expressed in such Senior Note (including
upon acceleration thereof) or

          (y)   the institution of any proceeding with respect to this Indenture
or the Senior Notes or any remedy thereunder, including without limitation
acceleration, by the holders of a majority in principal amount of the
outstanding Senior Notes; provided that, upon institution of any proceeding or
exercise of any remedy such holders provide the Trustee with prompt written
notice thereof.

          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 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, 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 the holder of the Senior Note.

Section 6.08.  Collection Suit by Trustee.

          If an Event of Default specified in Section 6.01(a) or (b) hereof
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), the Company's creditors or
the Company's 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 of a Note 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 of the Senior Notes, 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 which the holders of the Senior Notes may
be entitled to receive in such proceeding whether in liquidation or under any
plan of reorganization or arrangement or otherwise.  Nothing contained herein
shall be deemed to authorize the Trustee to authorize or consent to or accept or
adopt on behalf of any holder of a Note any plan of reorganization, arrangement,
adjustment or composition affecting the Senior Notes or the rights of any holder
of a Note thereof, or to authorize the Trustee to vote in respect of the claim
of any holder of a Note in any such proceeding.


Section 6.10.  Priorities.

          If the Trustee collects any money pursuant to this Article 6, it shall
pay out the money in the following order:


                                    57     
<PAGE>
 
          First:  to the Trustee, its agents and attorneys for amounts due under
Section 7.07 hereof, including payment of all compensation, expense and
liabilities incurred, and all advances made, by the Trustee and the costs and
expenses of collection;

          Second:  (i) first to holders of Senior Notes, for amounts due and
unpaid on such Senior Notes for interest, ratably, without preference or
priority of any kind, according to the amounts due and payable on the Senior
Notes for interest, and (ii) second, to the extent any other monies are
available, to holders of all Senior Notes for amounts due and unpaid on all such
Senior Notes for principal and premium and Liquidated Damages, if any, ratably,
without preference or priority of any kind, according to the amounts due and
payable on the Senior Notes for principal and premium and Liquidated Damages, if
any; and

          Third:  to the Company or to such party as a court of competent
jurisdiction shall direct.

          The Trustee may fix a record date and payment date for any such
payment to holders of Senior Notes.

Section 6.11.  Undertaking for Costs.

          In any suit for the enforcement of any right or remedy under this
Indenture or in any suit against the Trustee for any action taken or omitted by
it as a Trustee, a court in its discretion may require the filing by any party
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.
This Section 6.11 does not apply to a suit by the Trustee, a suit by a holder of
a Senior Note pursuant to Section 6.07 hereof, or a suit by holders of more than
10% in principal amount of the then outstanding Senior Notes.

                                    TRUSTEE

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 shall use the same degree of care and skill in their 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 Trustee need perform only
     those duties that are specifically set forth in this Indenture and no
     others, and no implied 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 

                                      58
<PAGE>
 
     opinions furnished to the Trustee and conforming to the requirements of
     this Indenture. 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 7.01;

          (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 7.01.

          (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

provided to the Trustee security and indemnity satisfactory to the Trustee
against any loss, liability or expense.

received by it except as the Trustee may agree in writing with the Company.

Section 7.02.   Rights of Trustee.

          (a)   The Trustee may conclusively rely upon any document believed by
it to be genuine and to have been signed or presented by the proper Person.  The
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 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.

          (c)   The Trustee may act through its attorneys and agents and shall
not be responsible for the misconduct or negligence of any agent appointed with
due care.

powers conferred upon it by this Indenture.


                                      59
<PAGE>
 
          (e)  Unless otherwise specifically provided in this Indenture, any
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 provided 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
Commission 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.


Section 7.04.  Trustee's Disclaimer.

          The Trustee shall not be responsible for and makes no representation
as to the validity or adequacy of this Indenture or the Senior Notes, it shall
not be accountable for the Company's use of the proceeds from the Senior Notes
or any money paid to the Company or upon the Company's direction under any
provision of this Indenture, it shall not be responsible for the use or
application of any money received by any Paying Agent other than the Trustee,
and it shall not be responsible for any statement or recital herein or any
statement in the Senior Notes or any other document in connection with the sale
of the Senior Notes or pursuant to this Indenture other than its certificate of
authentication.


Section 7.05.  Notice of Defaults.

          If a Default or Event of Default occurs and is continuing and if it is
known to a Responsible Officer of the Trustee, the Trustee shall mail to holders
of Senior Notes a 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 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 15th beginning with the May 15th
following the date of this Indenture, the Trustee shall mail to the holders of
the Senior Notes a brief report dated as of such reporting date that complies
with TIA (S) 313(a) (but if no event described in TIA (S) 313(a) has occurred
within the twelve months preceding the reporting date, no report need be
transmitted).  The Trustee also shall comply with TIA (S) 313(b)(2).  The
Trustee shall also transmit by mail all reports as required by TIA (S) 313(c).


                                      60
<PAGE>
 
          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 Commission and
each stock exchange on which the Senior Notes are listed. 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. The
Trustee's compensation 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, except any such
loss, liability or expense as may be attributable to the negligence or bad faith
of the Trustee. 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, in
its sole discretion, may elect to have separate counsel selected by it and the
Company shall pay the reasonable fees and expenses of such counsel. The Company
need not pay for any settlement made without its consent, which consent shall
not be unreasonably withheld.

          The obligations of the Company under this Section 7.07 shall survive
the satisfaction and discharge of this Indenture.

          To secure the Company' payment obligations in this Section 7.07, 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,
premium, if any, interest and Liquidated Damages, if any, 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.


Section 7.08.  Replacement of Trustee.

          A resignation or removal of the Trustee and appointment of a successor
Trustee shall become effective only upon the successor Trustee's acceptance of
appointment as provided in this Section 7.08.

          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 a majority
in principal amount of the then

                                      61
<PAGE>
 
outstanding Senior Notes may remove the Trustee by so notifying the Trustee and
the Company in writing. The Company may remove the Trustee if:

          (a)  the Trustee fails to comply with Section 7.10 hereof;

          (b)  the Trustee is adjudged a bankrupt or an insolvent or an order
     for relief is entered with respect to the Trustee under any Bankruptcy Law;

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

          (d)  the Trustee becomes incapable of acting.

          If the Trustee resigns or is removed or if a vacancy exists in the
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 hereof, 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 duties of the Trustee
under this Indenture.  The successor Trustee shall mail a notice of its
succession to holders of the Senior Notes.  The retiring Trustee shall promptly
transfer all property held by it as Trustee to the successor Trustee, provided
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 which shall be a
corporation organized and doing business under the laws of the United States of
America or of any state thereof authorized under such laws to exercise corporate
trustee power, shall be subject to supervision or examination by federal or
state authority and shall have a combined capital and surplus of at least $25.0
million as set forth in its most recent published annual report of condition.

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


Section 7.11.  Preferential Collection of Claims Against Company.

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

                   LEGAL DEFEASANCE AND COVENANT DEFEASANCE

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 and at any time, with respect
to the Senior Notes, 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 8.


Section 8.02.  Legal Defeasance and Discharge.

          Upon the Company's exercise under Section 8.01 hereof of the option
applicable to this Section 8.02, the Company shall be deemed to have been
discharged from its obligations with respect to all outstanding Senior Notes on
the date the conditions set forth in Section 8.04 are satisfied (hereinafter,
"Legal Defeasance").  For this purpose, such 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 of 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 which shall survive until otherwise terminated or discharged
hereunder: (a) the rights of holders of outstanding Senior Notes to receive from
the trust described below payments in respect of the principal of, premium, if
any, and interest on and Liquidated Damages with respect to such Senior Notes
when such payments are due, or on the redemption date, as the case may be; (b)
the Company's obligations with respect to the Senior Notes concerning issuing
temporary Senior Notes, registration of Senior Notes, mutilated, destroyed, lost
or stolen Senior Notes and the maintenance of an office or agency for payment
and money for security payments held in trust; (c) the rights, powers, trust,
duties and immunities of the Trustee,

                                      63
<PAGE>
 
and the Company's obligations in connection therewith; and (d) the Legal
Defeasance provisions of this Indenture.

Section 8.03.  Covenant Defeasance.

          Upon the Company's exercise under Section 8.01 hereof of the option
applicable to this Section 8.03, the Company shall be released from its
obligations under the covenants contained in Sections 4.03, 4.04, 4.05, 4.07,
4.08, 4.09, 4.10, 4.11, 4.12, 4.13, 4.15, 4.16, 4.17 and 4.18 hereof and Article
5 hereof with respect to the outstanding Senior Notes on and after the date the
conditions set forth in Section 8.04 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, such 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
the Company's exercise under Section 8.01 hereof of the option applicable to
this Section 8.03, subject to the satisfaction of the conditions set forth in
Section 8.04 hereof, Sections 6.01(d) through 6.01(f) hereof shall not
constitute Events of Default.

     any, and interest on the outstanding Senior Notes, on the stated maturity
     or on the applicable optional redemption date, as the case may be, of such
     principal or installment of principal of, premium, if any, or interest on

     or (ii) since the Issue Date, there has been a change in the applicable
     federal income tax law, in either case to the effect that, and based
     thereon such opinion of counsel shall confirm that, the holders of the
     outstanding Senior Notes will not recognize income, gain or loss for

                                      64

     federal income tax purposes as a result of such Legal Defeasance and will

     had not occurred;

          (c)  In the case of Covenant Defeasance, the Company shall have
     delivered to the Trustee an opinion of counsel in the United States
     reasonably acceptable to the Trustee confirming that the holders of the
     outstanding Senior Notes will not recognize income, gain or loss for
     federal income tax purposes as a result of such Covenant Defeasance and
     will be subject to federal income tax on the same amounts, in the same
     manner and at the same times as would have been the case if such Covenant
     Defeasance had not occurred;

          (d)  No Default or Event of Default shall have occurred and be
     continuing on the date of such deposit (other than a Default or Event of
     Default resulting from the borrowing of funds to be applied to such
     deposit) or insofar as Events of Default from bankruptcy or insolvency
     events 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 shall 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
     counsel to the effect that after the 91st day (or such other applicable
     date) following the deposit, the trust funds will not be subject to the
     effect of any applicable bankruptcy, insolvency, reorganization or similar
     laws affecting creditors' rights generally;

          (g)  The Company shall have delivered to the Trustee an Officers'
     Certificate stating that the deposit was not made by the Company with the
     intent of preferring the holders of Senior Notes over the other creditors
     of the Company with the intent of defeating, hindering, delaying or
     defrauding creditors of the Company or others; and

          (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
     Defeasance have been complied with.


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 Government Securities
(including the proceeds thereof) deposited with the Trustee (or other qualifying
trustee, collectively for purposes of this Section 8.05, the "Trustee") pursuant
to Section 8.04 hereof in respect of the outstanding Senior Notes shall be held
in trust and applied by the Trustee, in accordance with the provisions of such
Senior Notes and this Indenture, to the payment, either directly or through any
Paying Agent (including the Company acting as Paying Agent) as the Trustee may
determine, to the holders of such Senior Notes of all sums due and to become due
thereon in respect of principal, premium, if any, and interest, but such money
and Government Securities (including any proceeds thereof) need not be
segregated from other funds except to the extent required by law.

                                      65
<PAGE>
 
     The Company shall pay and indemnify the Trustee against any tax, fee or
other charge imposed on or assessed against the cash or Government Securities
deposited pursuant to Section 8.04 hereof or the principal and interest received
in respect thereof other than any such tax, fee or other charge which by law is
for the account of the holders of the outstanding Senior Notes.

     Anything in this Article 8 to the contrary notwithstanding, the Trustee
shall deliver or pay to the Company from time to time upon the request of the
Company any money or Government Securities 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 which would then be required to be deposited to
effect an equivalent Legal Defeasance or Covenant Defeasance.


Section 8.06.  Repayment to Company.

     Any money deposited with the Trustee or any Paying Agent, or then held by
the Company, in trust for the payment of the principal of, premium, or interest
on any Senior Note and remaining unclaimed for two years after such principal,
and premium, if any, or interest has become due and payable shall be paid to the
Company on its written 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 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 trustee thereof, shall thereupon cease; provided,
however, that the Trustee or such Paying Agent, before being required to make
any such repayment, may at the expense of the Company cause to be published
once, in the New York Times and The Wall Street Journal (national edition),
notice that such money remains unclaimed and that, after a date specified
therein, which shall not be less than 30 days from the date of such notification
or publication, any unclaimed balance of such money then remaining will be
repaid to the Company.


Section 8.07.  Reinstatement.

     If the Trustee or Paying Agent is unable to apply any United States
Dollars or 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
hereof, as the case may be; provided, however, that, if the Company makes any
payment of principal of, premium, if any, or interest 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.

                       AMENDMENT, SUPPLEMENT AND WAIVER

Section 9.01.  Without Consent of Holders of Senior Notes.

     Notwithstanding Section 9.02 hereof, the Company and the Trustee may amend
or supplement this Indenture or the Senior Notes without the consent of any
holder of Senior Notes:

     (a)  to cure any ambiguity, defect or inconsistency;

     (b)  to provide for uncertificated Senior Notes in addition to or in place
          of certificated Senior Notes;

     (c)  to provide for the assumption of the Company's obligations to holders
          of the Senior Notes in the case of a merger or consolidation;

     (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 under this Indenture of any such holder; or

     (e)  to comply with requirements of the Commission in order to effect or
          maintain the qualification of this Indenture under the Trust Indenture
          Act.

     Upon the request of the Company accompanied by a resolution of the Board
of Directors of the Company authorizing the execution of any such amended or
supplemental Indenture, 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 authorized or permitted by
the terms of this Indenture and to make any further appropriate agreements and
stipulations which may be therein contained, but the Trustee shall not be
obligated to enter into such amended or supplemental Indenture which affects its
own rights, duties or immunities under this Indenture or otherwise.


Section 9.02.  With Consent of Holders of Senior Notes.

     The Company and the Trustee may amend or supplement this Indenture or the
Senior Notes or any amended or supplemental Indenture with the written consent
of the holders of Senior Notes of at least a majority in aggregate principal
amount of the Senior Notes then outstanding (including consents obtained in
connection with a tender offer or exchange offer for the Senior Notes), and any
existing Default and its consequences or compliance with any provision of this
Indenture or the Senior Notes may be waived with the consent of the holders of a
majority in principal amount of the then outstanding Senior Notes (including
consents obtained in connection with a tender offer or exchange offer for the
Senior Notes).

     Upon the request of the Company accompanied by a resolution of the Board
of Directors of the Company 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 

                                      67
<PAGE>
 
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 9.02 becomes
effective, the Company shall mail to the holders of Senior Notes 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,
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 or the Senior Notes.  However, without the
consent of each holder affected, an amendment or waiver may not (with respect to
any Senior Notes held by a non-consenting holder of Senior Notes):

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

    (ii)  reduce the principal of or change the fixed maturity of any Note or
          alter the provisions with respect to the redemption of the Senior
          Notes (other than Sections 3.09 and 4.15 hereof);

   (iii)  reduce the rate of or change the time for payment of interest on any
          Senior Notes;

    (iv)  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 Senior Notes and a
          waiver of the payment default that resulted from such acceleration);

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

    (vi)  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, premium, if any, or interest on the
          Senior Notes;

   (vii)  waive a redemption payment with respect to any Senior Note (other than
          a payment required by Sections 3.09 or 4.15 hereof); or

  (viii)  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 or the Senior Notes shall
be set forth in a amended or supplemental Indenture that complies with the TIA
as then in effect.

                                      68
<PAGE>
 
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 of a
Senior Note and every subsequent holder of a Senior Note or portion of a 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 of a Senior Note or subsequent holder of a 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 of a Senior Note.

     The Company may fix a record date for determining which holders of the
Senior Notes must consent to such amendment, supplement or waiver.  If the
Company fixes a record date, the record date shall be fixed at (i) the later of
30 days prior to the first solicitation of such consent or the date of the most
recent list of holders of Senior Notes furnished to the Trustee prior to such
solicitation pursuant to Section 2.05 hereof or (ii) such other date as the
Company shall designate.


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 9 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.

Section 9.07.  Payment for Consents.

     The Company shall not, and shall not permit any of its Subsidiaries to,
directly or indirectly, pay or cause to be paid any consideration, whether by
way of interest, fee or otherwise, to any holder of Senior Notes for or as an
inducement to any consent, waiver or amendment of any of the terms or provisions
of this Indenture or the Senior Notes, unless such consideration is offered to
be paid or agreed to be paid to all holders of the Senior Notes that consent,
waive or agree to amend in the time frame set forth in the solicitation
documents relating to such consent, waiver or agreement.

          If a notice or communication is mailed in the manner provided above
within the time prescribed, it is duly given, whether or not the addressee
receives it.

          If the Company mails a notice or communication to holders of Senior
Notes, it shall mail a copy to the Trustee and each Agent at the same time.


Section 10.03. Communication by Holders of Senior Notes with Other Holders of
               Senior Notes.

          Holders of the Senior Notes may communicate pursuant to TIA (S) 312(b)
with other holders of Senior Notes with respect to their rights under this
Indenture or the Senior Notes. The Company, the Trustee, the Registrar and
anyone else shall have the protection of TIA (S) 312(c).


Section 10.04. 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 10.05 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

     has read such covenant or condition;

Section 10.06. Rules by Trustee and Agents.

          The Trustee may make reasonable rules for action by or at a meeting of
holders of Senior Notes.  The Registrar or Paying Agent may make reasonable
rules and set reasonable requirements for its functions.


Section 10.07. No Personal Liability of Partners, Directors, Officers, Employees
               and Stockholders.

Company, as such, shall have any liability for any obligations of the Company
under the Senior Notes or this Indenture or for any claim based on, in respect
of, or by reason of, such obligations or their creation.  Each holder of the
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 Commission that such a waiver is
against public policy.


Section 10.08. Governing Law.

          The internal law of the State of New York shall govern and be used to
construe this Indenture and the Senior Notes.


Section 10.09. No Adverse Interpretation of Other Agreements.

shall bind its successors. All agreements of the Trustee in this Indenture shall
bind its successor.


Section 10.11. Severability.

          In case any provision in this Indenture or in the Senior Notes shall
be invalid, illegal or unenforceable, the validity, legality and enforceability
of the remaining provisions shall not in any way be affected or impaired
thereby.


Section 10.12. Counterpart Originals.

          The parties may sign any number of copies of this Indenture. Each
signed copy shall be an original, but all of them together represent the same
agreement.

     Capitalized terms used herein have the meanings assigned to them in the
Indenture (as defined below) unless otherwise indicated.

     1.   Interest.  Intermedia Communications Inc., a Delaware corporation (the
"Company"), promises to pay interest on the principal amount of this Senior Note
at the rate and in the manner specified below.  Interest will accrue at a rate
of 8 7/8% and will be payable semi-annually, in arrears, on May 1 and November 1
of each year, commencing on May 1, 1998 or if any such day is not a Business Day
on the next succeeding Business Day (each an "Interest Payment Date") to holders
of record of the Senior Notes at the close of business on the immediately
preceding April 15 and October 15, whether or not a Business Day. Interest 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 Issue Date. Interest will
be computed on the basis of a 360-day year comprised of twelve 30-day months. To
the extent lawful, the Company shall pay interest on overdue principal at the
then applicable interest rate on the Senior Notes; it shall pay interest on
overdue installments of interest (without regard to any applicable grace
periods) at the same rate to the extent lawful.

     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 record date 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.  The holder hereof must surrender this
Senior Note to a Paying Agent to collect principal payments.  Principal,
premium, Liquidated Damages, if any, and interest on the Senior Notes will be
payable by wire transfer of immediately available funds to the accounts
specified by the holders thereof or if no such account(s) is specified, by
mailing a check to the address set forth for such holder in the register of the
holders of Senior Notes.  Unless otherwise designated by the Company, the
Company's office or agency in New York will be the office of the Trustee
maintained for such purpose.

     3.   Paying Agent and Registrar.  Initially, the Trustee will act as Paying
Agent and Registrar.  The Company may change any Paying Agent, Registrar or co-
registrar without prior notice to any holder of a Note.  The Company may act in
any such capacity.

     4.   Indenture.  The Company issued the Senior Notes under an Indenture,
dated as of October 30, 1997 (the "Indenture"), between the Company and the
Trustee.  The terms of the Senior Notes include those stated in the Indenture
and those made part of the Indenture by reference to the Trust Indenture Act of
1939, as amended (15 U.S. Code (S)(S) 77aaa-77bbbb), as in effect on the date of
the Indenture.  The Senior Notes are subject to all such terms, and holders of
Senior Notes are referred to the Indenture and such act for a statement of such
terms.  The terms of the Indenture shall govern any inconsistencies between the
Indenture and the Senior Notes.  The Senior Notes are obligations of the Company
limited to the sum of $250,000,000 in aggregate principal amount of Senior Notes
($285,000,000 in aggregate principal amount if the Initial Purchasers exercise
their over-allotment option as described in the Offering Memorandum).

     5.   Optional Redemption.  The Senior Notes will not be redeemable at the
Company's option prior to November 1, 2002.  Thereafter, the Senior Notes will
be subject to redemption at the option of the Company, in whole or in part, upon
not less than 30 nor more than 60 days' notice to the holders thereof, at the
redemption prices (expressed as percentages of principal amount) set forth below
plus accrued and unpaid interest and Liquidated Damages, if any, thereon to the
applicable redemption date, if redeemed during the twelve-month period beginning
on November 1 of the years indicated below:

<PAGE>
 
          YEAR                                           PERCENTAGE

          2002 .........................................   104.438%
          2003 .........................................   102.958%
          2004 .........................................   101.479%
          2005 .........................................   100.000%


     Notwithstanding the provisions of Section 3.07(a) of the Indenture, in the
event of the sale by the Company prior to November 1, 2000 of its Capital Stock
(other than Disqualified Stock) (i) to a Strategic Investor in a single
transaction or series of related transactions for an aggregate purchase price
equal to or exceeding $50.0 million or (ii) in one or more Public Offerings,  up
to a maximum of 25% of the aggregate principal amount of the Senior Notes
originally issued shall, at the option of the Company, be redeemable from the
net cash proceeds of such sale or sales to such Strategic Investor (but only to
the extent such proceeds consist of cash or readily marketable cash equivalents
received in respect of the Capital Stock, other than Disqualified Stock, so
sold) at a redemption price equal to 108.875% of the principal amount thereof
plus accrued and unpaid interest and Liquidated Damages, if any, thereon to the
redemption date; provided that at least 75% of the aggregate principal amount of
the Senior Notes originally issued remains outstanding immediately after the
occurrence of such redemption and that such redemption occurs within 90 days of
the date of the closing of such sale.

     6.   Mandatory Redemption.  Except as set forth in Sections 3.09 and 4.15
of the Indenture, the Company will not be required to make mandatory redemption
or sinking fund payments with respect to the Senior Notes.

     7.   Repurchase at Option of holder.  (a)  Upon the occurrence of a Change
of Control, the Company shall be required to make an offer to repurchase on the
Change of Control Payment Date all or any part (equal to $1,000 or an integral
multiple thereof) of the outstanding 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 thereon to the Change of Control Payment Date.
Holders of Senior Notes that are subject to an offer to purchase will receive a
Change of Control Offer from the Company prior to any related Change of Control
Payment Date and may elect to have such Senior Notes purchased by completing the
form entitled "Option of Holder to Elect Purchase" appearing below.

     (b)  The Company shall be required when the cumulative amount of Excess
Proceeds from Asset Sales exceeds $5.0 million to offer to purchase the maximum
principal amount of Senior Notes and Pari Passu Notes that may be purchased out
of the Excess Proceeds, at an offer price in cash in an amount equal to 100% of
the outstanding principal amount of the Senior Notes and 100% of the accreted
value or 100% of the outstanding principal amount, as applicable, of the Pari
Passu Notes, plus accrued and unpaid interest and Liquidated Damages thereon, if
any, to the date fixed for the closing of such accordance with the procedures
set forth in Section 3.09 of the Indenture.  If the principal amount and/or
aggregate accreted value, as the case may be, of Senior Notes and Pari Passu
Notes surrendered by holders thereof exceeds the amount of Excess Proceeds, the
Trustee shall select the Senior Notes and Pari Passu 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 and Pari Passu Notes in denominations of
$1,000, or integral multiples thereof shall be purchased).  Holders of Senior
Notes that are the subject of an offer to purchase will receive an Excess
Proceeds Offer from the Company prior to any related purchase date and may elect
to have such Senior Notes purchased by completing the form entitled "Option of
Holder to Elect Purchase" appearing below.

                                      A-4
<PAGE>
 
     8.   Notice of Redemption.  Notice of redemption shall be mailed by first
class mail at least 30 days but not more than 60 days before the redemption date
to each holder of Senior Notes to be redeemed at its registered address.  Senior
Notes may be redeemed in part but only in whole multiples of $1,000, unless all
of the Senior Notes held by a holder of Senior Notes are to be redeemed.  If any
Senior Note is to be redeemed in part only, the notice of redemption that
relates to such Senior Note shall state the portion of the principal amount to
be redeemed. On and after the redemption date, interest ceases to accrue on
Senior Notes or portions of them called for redemption.

     9.   Denominations, Transfer, Exchange.  The Senior Notes are in registered
form without coupons in denominations of $1,000 and integral multiples of
$1,000.  The transfer of Senior Notes may be registered and Senior Notes may be
exchanged as provided in the Indenture.  The Registrar and the Trustee may
require a holder of a Senior Note, among other things, to furnish appropriate
endorsements and transfer documents and the Company may require a holder of a
Senior Note to pay any taxes and fees required by law or permitted by the
Indenture.  Neither the Company nor the Registrar need exchange or register the
transfer of any Senior Note or portion of a Senior Note selected for redemption.
Also, neither the Company nor the Registrar need exchange or register the
transfer of any Senior Notes for a period of 15 days before a selection of
Senior Notes to be redeemed.

     10.  Persons Deemed Owners.  Prior to due presentment to the Trustee for
registration of the transfer of this Senior Note, the Trustee, any Agent and the
Company shall deem and treat the Person in whose name this Senior Note is
registered as its absolute owner for the purpose of receiving payment of
principal of, premium, Liquidated Damages, if any, and interest on this Senior
Note and for all other purposes whatsoever, whether or not this Senior Note is
overdue, and neither the Trustee, any Agent nor the Company shall be affected by
notice to the contrary.  The registered holder of a Senior Note shall be treated
as its owner for all purposes.

     11.  Amendments, Supplement and Waivers.  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 Senior
Notes then outstanding (including consents obtained in connection with a tender
offer or exchange offer for Senior Notes), and any existing default or
compliance with any provision of the Indenture or the Senior Notes may be waived
with the consent of the holders of a majority in principal amount of the then
outstanding Senior Notes (including consents obtained in connection with a
tender offer or exchange offer for Senior Notes).  Without the consent of any
holder of a Senior Note, the Indenture 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 Commission in order
to effect or maintain the qualification of the Indenture under the Trust
Indenture Act.  However, without the consent of each holder affected, an
amendment or waiver may not (with respect to any Senior Notes held by a non-
consenting holder of Senior Notes) reduce the principal amount of Senior Notes
whose holders must consent to an amendment, supplement or waiver; reduce the
principal of or change the fixed maturity of any Senior Note or alter the
provisions with respect to the redemption of the Senior Notes (other than a
payment required by Section 3.09 or Section 4.15 of the Indenture); reduce the
rate of or change the time for payment of interest on any Senior Notes; 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 Senior Notes and a waiver of the payment default that resulted from such
acceleration); make any Senior Note payable in money other than that stated in
the Senior Notes; make any change in the

                                      A-5
<PAGE>
 
provisions of the Indenture relating to waivers of past Defaults or the rights
of holders of Senior Notes to receive payments of principal of, premium, if any,
or interest on the Senior Notes; waive a redemption payment with respect to any
Senior Note (other than a payment required by Section 3.09 or Section 4.15 of
the Indenture) or make any change in the foregoing amendment and waiver
provisions.

     12.  Defaults and Remedies.  Events of Default include:  default for 30
days in the payment when due of interest on the Senior Notes; default in payment
when due of principal or premium, if any, on the Senior Notes at maturity, upon
redemption or otherwise; failure by the Company to perform or comply with the
provisions described under Sections 4.07, 4.09, 4.10, 4.15 or 5.01 of the
Indenture; failure by the Company for 30 days after notice from the Trustee or
the holders of at least 25% in principal amount of the Senior Notes then
outstanding to comply with its other agreements in the Indenture or the Senior
Notes; default under any mortgage, indenture or instrument under which there may
be issued or by which there may be secured or evidenced any Indebtedness for
money borrowed by the Company or any 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 Issue Date, which
default (x) is caused by a Payment Default, and the principal amount of any such
Indebtedness, together with the principal amount of any other such Indebtedness
of the Company or any Significant Subsidiary under which there has been a
Payment Default or the maturity of which has been accelerated as provided in
clause (y), aggregates $5.0 million or more or (y) results in the acceleration
(which acceleration has not been rescinded) of such Indebtedness prior to its
express maturity and the principal amount of any such Indebtedness, together
with the principal amount of any other such Indebtedness under which there has
been a Payment Default or the maturity of which has been so accelerated,
aggregates $5.0 million or more; failure by the Company or any of its
Subsidiaries to pay final judgments (other than any judgment as to which a
reputable insurance company has accepted full liability in writing) aggregating
in excess of $5.0 million which judgments are not paid, discharged or stayed
within 45 days after their entry; and certain events of bankruptcy or insolvency
with respect to the Company or any of its Significant Subsidiaries. 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. Upon such declaration, the
principal of, premium, if any, and accrued and unpaid interest and Liquidated
Damages, if any, on the Senior Notes shall 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 or any of
its Significant Subsidiaries, the foregoing amount shall ipso facto 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. 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 or Liquidated Damages or premium on, or the
principal of, the Senior Notes.

     13.  Trustee Dealings with Company.  The Trustee under the Indenture, 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 Trustee; however, if the
Trustee acquires any conflicting interest,  it must eliminate such conflict
within 90 days, apply to the Commission for permission to continue as Trustee or
resign.

     14.  No Personal Liabilities of Directors, Officers, Employees and
Stockholders.  No director, officer, employee, incorporator or stockholder of
the 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
the Senior Notes by accepting a

                                      A-6
<PAGE>
 
Senior Note waives and releases all such liability. The waiver and release are
part of the consideration for 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 of a Senior Note 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 Senior Notes under the Indenture,
holders of Transfer Restricted Securities shall have all the rights set forth in
the Note 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 has directed the Trustee to
use CUSIP numbers in notices of redemption as a convenience to holders of Senior
Notes.  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 will furnish to any holder of a Senior Note upon written
request and without charge a copy of the Indenture.  Request may be made to:

          Intermedia Communications Inc., a Delaware corporation (the
"Company"), certifies that pursuant to the authority contained in ARTICLE FOURTH
of its Restated Certificate of Incorporation, as amended (the "Certificate of
Incorporation"), and in accordance with the provisions of Section 151 of the
General Corporation Law of the State of Delaware (the "DGCL"), the Board of
Directors of the Company at a special meeting duly called and held on October
21, 1997, duly approved and adopted the following resolution which resolution
remains in full force and effect on the date hereof:

          RESOLVED, that pursuant to the authority vested in the Board of
Directors by the Certificate of Incorporation, the Board of Directors does
hereby designate, create, authorize and provide for the issue of a series of
preferred stock having a par value of $1.00 per share, with a liquidation
preference of $2,500 per share (the "Liquidation Preference") which shall be
designated as Series E Junior Convertible Preferred Stock (the "Preferred
Stock") consisting of 87,500 shares (which shares of preferred stock were
authorized to be issued by the Company by resolution of the Board of Directors
of the Company dated as of March 17, 1997, and by resolution of the stockholders
of the Company dated as of May 22, 1997), having the following voting powers,
preferences and relative, participating, optional and other special rights, and
qualifications, limitations and restrictions thereof as follows:

     1.   Ranking.  The Preferred Stock shall rank, with respect to dividend
          -------                                                           
distributions and distributions upon the liquidation, winding-up and dissolution
of the Company, (i) senior to all classes of common stock of the Company and to
each other class of capital stock or series of preferred stock established after
October 24, 1997 by the Board of Directors the terms of which do not expressly
provide that it ranks senior to or on a parity with the Preferred Stock as to
dividend distributions and distributions upon the liquidation, winding-up and
dissolution of the Company (collectively referred to with the common stock of
the Company as "Junior Securities"); (ii) on a parity with Series D Preferred
Stock, any additional shares of Series D Preferred Stock or Preferred Stock
issued by the Company in the future and any other class of capital stock or
series of preferred stock issued by the Company established after October 24,
1997 by the Board of Directors, the terms of which expressly provide that such
class or 
<PAGE>
 
series will rank on a parity with the Preferred Stock as to dividend
distributions and distributions upon the liquidation, winding-up and dissolution
of the Company (collectively referred to as "Parity Securities"); and (iii)
junior to the Series B Preferred Stock and to each class of capital stock or
series of preferred stock issued by the Company established after October 24,
1997 by the Board of Directors the terms of which expressly provide that such
class or series will rank senior to the Preferred Stock as to dividend
distributions and distributions upon liquidation, winding-up and dissolution of
the Company (collectively referred to as "Senior Securities").

     No dividend whatsoever shall be declared or paid upon, or any sum set apart
for the payment of dividends upon, any outstanding share of the Preferred Stock
with respect to any dividend period unless all dividends for all preceding
dividend periods have been declared and paid, or declared and a sufficient sum
set apart for the payment of such dividend, upon all outstanding shares of
Senior Securities.

     2.     Dividends.
            --------- 

     (i)    The holders of shares of the Preferred Stock shall be entitled to
receive, when, as and if dividends are declared by the Board of Directors out of
funds of the Company legally available therefor, cumulative dividends from the
Preferred Stock Issue Date accruing at the rate per annum of 7% of the
Liquidation Preference per share, payable quarterly in arrears on each January
15, April 15, July 15 and October 15, commencing on January 15, 1998 (each a
"Dividend Payment Date").  If any such date is not a Business Day, such payment
shall be made on the next succeeding Business Day, to the holders of record as
of the next preceding January 1, April 1, July 1 and October 1 (each, a "Record
Date").  Dividends will be payable, at the option of the Company, (i) in cash,
(ii) by delivery of shares of Common Stock to holders (based upon 95% of the
Average Stock Price (as defined below)), or (iii) through any combination of the
foregoing.  If the dividends are paid in shares of Common Stock, the number of
shares of Common Stock to be issued on each Dividend Payment Date will be
determined by dividing the total dividend to be paid on each share of Preferred
Stock by 95% of the average of the high and low sales prices of the Common Stock
as reported by the Nasdaq National Market or any national securities exchange
upon which the Common Stock is then listed, for each of the ten consecutive
trading days immediately preceding the fifth Business Day preceding the Record
Date (the "Average Stock Price").  The Transfer Agent is hereby authorized and
directed to aggregate any fractional shares of Common Stock that are issued as
dividends, sell them at the best available price and distribute the proceeds to
the holders in proportion to their respective interests therein.  The Company
shall pay the expenses of the Transfer Agent with respect to such sale,
including brokerage commissions.  In the event the sale by the Transfer Agent of
such aggregated fractional interests would be restricted, the Company and the
Transfer Agent will agree upon other appropriate arrangements for the cash
realization of the fractional interests.  Dividends payable on the Preferred
Stock will be computed on the basis of a 360-day year consisting of twelve 30-
day months and will be deemed to accrue on a daily basis.

     (ii)   Dividends on the Preferred Stock shall accrue whether or not the
Company has earnings or profits, whether or not there are funds legally
available for the payment of such dividends and whether or not dividends are
declared.  Dividends will accumulate to the extent they are not paid on the
Dividend Payment Date for the period to which they relate.  The Company shall
take all actions required or permitted under the DGCL to permit the payment of
dividends on the Preferred Stock, including, without limitation, through the
revaluation of its assets in accordance with the DGCL, to make or keep funds
legally available for the payment of dividends.

     (iii)  No dividend whatsoever shall be declared or paid upon, or any sum
set apart for the payment of dividends upon, any outstanding share of the
Preferred Stock with respect to any dividend

                                       2
<PAGE>
 
period unless all dividends for all preceding dividend periods have been
declared and paid, or declared and a sufficient sum set apart for the payment of
such dividend, upon all outstanding shares of Preferred Stock. Unless full
cumulative dividends on all outstanding shares of Preferred Stock for all past
dividend periods shall have been declared and paid, or declared and a sufficient
sum for the payment thereof set apart, then: (a) no dividend (other than a
dividend payable solely in shares of any Junior Securities) shall be declared or
paid upon, or any sum set apart for the payment of dividends upon, any shares of
Junior Securities; (b) no other distribution shall be declared or made upon, or
any sum set apart for the payment of any distribution upon, any shares of Junior
Securities, other than a distribution consisting solely of Junior Securities;
(c) no shares of Junior Securities shall be purchased, redeemed or otherwise
acquired or retired for value (excluding an exchange for shares of other Junior
Securities) by the Company or any of its Subsidiaries; and (d) no monies shall
be paid into or set apart or made available for a sinking or other like fund for
the purchase, redemption or other acquisition or retirement for value of any
shares of Junior Securities by the Company or any of its Subsidiaries. Holders
of the Preferred Stock will not be entitled to any dividends, whether payable in
cash, property or stock, in excess of the full cumulative dividends as herein
described.

     (iv)   When dividends are declared by the Board of Directors, the Company
shall issue a press release at least 15 Business Days prior to the Record Date
setting forth (a) the method of payment for such dividends (cash, Common Stock
or a combination thereof) and (b) the pricing period used to determine the
Average Stock Price.

     3.     Conversion.
            ---------- 

     (i)    A holder of shares of Preferred Stock may convert such shares into
Common Stock at any time after December 29, 1997, unless previously redeemed.
For the purposes of conversion, each share of Preferred Stock shall be valued at
the Liquidation Preference, which shall be divided by the Conversion Price in
effect on the Conversion Date to determine the number of shares issuable upon
conversion, except that the right to convert shares of Preferred Stock called
for redemption shall terminate at the close of business on the Business Day
preceding the Redemption Date and shall be lost if not exercised prior to that
time, unless the Company shall default in payment of the Applicable Redemption
Price.  Immediately following such conversion, the rights of the holders of
converted Preferred Stock shall cease and the persons entitled to receive the
Common Stock upon the conversion of Preferred Stock shall be treated for all
purposes as having become the owners of such Common Stock.

     (ii)   To convert Preferred Stock, a holder must (A) surrender the
certificate or certificates evidencing the shares of Preferred Stock to be
converted, duly endorsed in a form satisfactory to the Company, at the office of
the Company or transfer agent for the Preferred Stock, (B) notify the Company at
such office that he elects to convert Preferred Stock and the number of shares
he wishes to convert, (C) state in writing the name or names in which he wishes
the certificate or certificates for shares of Common Stock to be issued, and (D)
pay any transfer or similar tax if required.  In the event that a holder fails
to notify the Company of the number of shares of Preferred Stock which he wishes
to convert, he shall be deemed to have elected to convert all shares represented
by the certificate or certificates surrendered for conversion.  The date on
which the holder satisfies all those requirements is the "Conversion Date."  As
soon as practical, the Company shall deliver a certificate for the number of
full shares of Common Stock issuable upon the conversion, and a new certificate
representing the unconverted portion, if any, of the shares of Preferred Stock
represented by the certificate or certificates surrendered for conversion.  The
person in whose name the Common Stock certificate is registered shall be treated
as the stockholder of record on and after the Conversion Date.  No payment or
adjustment will be made for accrued and unpaid dividends on converted shares of
Preferred Stock or for dividends on 

                                       3
<PAGE>
 
any Common Stock issued upon such conversion. A share of Preferred Stock
surrendered for conversion during the period from the close of business on any
record date for the payment of dividends to the opening of business of the
corresponding Dividend Payment Date must be accompanied by a payment in cash,
Common Stock or a combination thereof, in an amount equal to the dividend
payable on such Dividend Payment Date, unless such share of Preferred Stock has
been called for redemption on a redemption date occurring during the period from
the close of business on any record date for the payment of dividends to the
close of business on the Business Day immediately following the corresponding
Dividend Payment Date. The dividend payment with respect to a share of Preferred
Stock called for redemption on a date during the period from the close of
business on any record date for the payment of dividends to the close of
business on the Business Day immediately following the corresponding Dividend
Payment Date will be payable on such Dividend Payment Date to the record holder
of such share on such record date, notwithstanding the conversion of such share
after such record date and prior to such Dividend Payment Date, and the holder
converting such share of Preferred Stock need not include a payment of such
dividend amount upon surrender of such share of Preferred Stock for conversion.
If a holder of Preferred Stock converts more than one share at a time, the
number of full shares of Common Stock issuable upon conversion shall be based on
the total liquidation preference of all shares of Preferred Stock converted. If
the last day on which Preferred Stock may be converted is not a Business Day,
Preferred Stock may be surrendered for conversion on the next succeeding
Business Day.

     (iii)  The Company shall not issue any fractional shares of Common Stock
upon conversion of Preferred Stock.  Instead the Company shall round the results
of a conversion up to the nearest full share of Common Stock.

     (iv)   If a holder converts shares of Preferred Stock, the Company shall
pay any documentary, stamp or similar issue or transfer tax due on the issue of
shares of Common Stock upon the conversion. However, the holder shall pay any
such tax that is due because the shares are issued in a name other than the
holder's name.

     (v)    The Company has reserved and shall continue to reserve out of its
authorized but unissued Common Stock or its Common Stock held in treasury enough
shares of Common Stock to permit the conversion of the Preferred Stock in full.
All shares of Common Stock that may be issued upon conversion of Preferred Stock
shall be fully paid and nonassessable.  The Company shall endeavor to comply
with all securities laws regulating the offer and delivery of shares of Common
Stock upon conversion of Preferred Stock and shall endeavor to list such shares
on each national securities exchange or automated quotation system on which the
Common Stock is listed.

     (vi)   In case the Company shall pay or make a dividend or other
distribution on any class of capital stock of the Company in Common Stock other
than the payment of dividends in Common Stock on the Preferred Stock or any
other regularly scheduled dividend on any other preferred stock which does not
trigger any anti-dilution provisions in any other security, the Conversion Price
in effect at the opening of business on the day following the date fixed for the
determination of stockholders entitled to receive such dividend or other
distribution shall be reduced by multiplying such Conversion Price by a fraction
the numerator of which shall be the number of shares of Common Stock outstanding
at the close of business on the date fixed for such determination and the
denominator of which shall be the sum of such number of shares and the total
number shares constituting such dividend or other distribution, such reduction
to become effective immediately after the opening of business on the day
following the date fixed for such determination of the holders entitled to such
dividends and distributions. For the purposes of this paragraph 3(vi), the
number of shares of Common Stock at any time outstanding shall not include

                                       4
<PAGE>
 
shares held in the treasury of the Company.  The Company will not pay any
dividend or make any distribution on shares of Common Stock held in the treasury
of the Company.

     (vii)  In case the Company shall issue rights, options or warrants to all
holders of its Common Stock entitling them to subscribe for, purchase or acquire
shares of Common Stock at a price per share less than the current market price
per share (determined as provided in paragraph 3(xi) below) of the Common Stock
on the date fixed for the determination of stockholders entitled to receive such
rights, options or warrants, the Conversion Price in effect at the opening of
business on the day following the date fixed for such determination shall be
reduced by multiplying such Conversion Price by a fraction the numerator of
which shall be the number of shares of Common Stock outstanding at the close of
business on the date fixed for such determination plus the number of shares of
Common Stock which the aggregate of the offering price of the total number of
shares of Common Stock so offered for subscription, purchase or acquisition
would purchase at such current market price and the denominator of which shall
be the number of shares of Common Stock outstanding at the close of business on
the date fixed for such determination plus the number of shares of Common Stock
so offered for subscription, purchase or acquisition, such reduction to become
effective immediately after the opening of business on the day following the
date fixed for such determination of the holders entitled to such rights,
options or warrants.  However, upon the expiration of any right, option or
warrant to purchase Common Stock, the issuance of which resulted in an
adjustment in the Conversion Price pursuant to this paragraph 3(vii), if any
such right, option or warrant shall expire and shall not have been exercised,
the Conversion Price shall be recomputed immediately upon such expiration and
effective immediately upon such expiration shall be increased to the price it
would have been (but reflecting any other adjustments to the Conversion Price
made pursuant to the provisions of this paragraph 3 after the issuance of such
rights, options or warrants) had the adjustment of the Conversion Price made
upon the issuance of such rights, options or warrants been made on the basis of
offering for subscription or purchase only that number of shares of Common Stock
actually purchased upon the exercise of such rights, options or warrants.  No
further adjustment shall be made upon exercise of any right, option or warrant
if any adjustment shall have been made upon the issuance of such security.  For
the purposes of this paragraph 3(vii), the number of shares of Common Stock at
any time outstanding shall not include shares held in the treasury of the
Company.  The Company will not issue any rights, options or warrants in respect
of shares of Common Stock held in the treasury of the Company.

     (viii) In case the outstanding shares of Common Stock shall be subdivided
into a greater number of shares of Common Stock, the Conversion Price in effect
at the opening of business on the day following the day upon which such
subdivision becomes effective shall be reduced, and, conversely, in case the
outstanding shares of Common Stock shall each be combined into a smaller number
of shares of Common Stock, the Conversion Price in effect at the opening of
business on the day following the day upon which such combination becomes
effective shall be increased to equal the product of the Conversion Price in
effect on such date and a fraction the numerator of which shall be the number of
shares of Common Stock outstanding immediately prior to such subdivision or
combination, as the case may be, and the denominator of which shall be the
number of shares of Common Stock outstanding immediately after such subdivision
or combination, as the case may be.  Such reduction or increase, as the case may
be, shall become effective immediately after the opening of business on the day
following the day upon which such subdivision or combination becomes effective.

     (ix)   In case the Company shall, by dividend or otherwise, distribute to
all holders of its Common Stock (A) evidences of its indebtedness or (B) shares
of any class of capital stock, cash or other assets (including securities, but
excluding (x) any rights, options or warrants referred to in paragraph 3(vii)
above, (y) any dividend or distribution referred to in paragraph 3(vi) or
3(viii) above, and (z) cash

                                       5
<PAGE>
 
dividends paid from the Company's retained earnings), unless the sum of (1) all
such cash dividends and distributions made within the preceding 12 months in
respect of which no adjustment has been made and (2) any cash and the fair
market value of other consideration paid in respect of any repurchases of Common
Stock by the Company or any of its subsidiaries within the preceding 12 months
in respect of which no adjustment has been made, exceeds 20% of the Company's
market capitalization (being the product of the then current market price per
share (determined as provided in paragraph 3(xi) below) of the Common Stock
times the aggregate number of shares of Common Stock then outstanding on the
record date for such distribution), then in each case, the Conversion Price in
effect at the opening of business on the day following the date fixed for the
determination of holders of Common Stock entitled to receive such distribution
shall be adjusted by multiplying such Conversion Price by a fraction of which
the numerator shall be the current market price per share (determined as
provided in paragraph 3(xi) below) of the Common Stock on such date of
determination (or, if earlier, on the date on which the Common Stock goes "ex-
dividend" in respect of such distribution) less the then fair market value as
determined by the Board of Directors (whose determination shall be conclusive
and shall be described in a statement filed with the Transfer Agent) of the
portion of the capital stock, cash or other assets or evidences of indebtedness
so distributed (and for which an adjustment to the Conversion Price has not
previously been made pursuant to the terms of this paragraph 3) applicable to
one share of Common Stock, and the denominator shall be such current market
price per share of the Common Stock, such adjustment to become effective
immediately after the opening of business on the day following such date of
determination of the holders entitled to such distribution.  The following
transactions shall be excluded from the foregoing clauses (1) and (2): (I)
repurchases of Common Stock issued under the Company's stock incentive programs;
and (II) dividends or distributions payable-in-kind in additional shares of, or
warrants, rights, calls or options exercisable for or convertible into
additional shares of Junior Securities.

     (x)    The reclassification or change of Common Stock into securities,
including securities other than Common Stock, (other than any reclassification
upon a consolidation or merger to which paragraph 3(xviii) below shall apply)
shall be deemed to involve (A) a distribution of such securities other than
Common Stock to all holders of Common Stock (and the effective date of such
reclassification shall be deemed to be "the date fixed for the determination of
holders of Common Stock entitled to receive such distribution" within the
meaning of paragraph 3(ix) above), and (B) a subdivision or combination, as the
case may be, of the number of shares of Common Stock outstanding immediately
prior to such reclassification into the number of shares of Common Stock
outstanding immediately thereafter (and the effective date of such
reclassification shall be deemed to be "the day upon which such subdivision
becomes effective" or "the day upon which such combination becomes effective,"
as the case may be, and "the day upon which such subdivision or combination
becomes effective" within the meaning of paragraph 3(viii) above).

     (xi)   For the purpose of any computation under paragraph 3(vii) or 3(ix)
above, the current market price per share of Common Stock on any day shall be
deemed to be the average of the Closing Prices of the Common Stock for the 20
consecutive Trading Days selected by the Board of Directors commencing no more
than 30 Trading Days before and ending no later than the day before the day in
question; provided that, in the case of paragraph 3(ix), if the period between
the date of the public announcement of the dividend or distribution and the date
for the determination of holders of Common Stock entitled to receive such
dividend or distribution (or, if earlier, the date on which the Common Stock
goes "ex-dividend" in respect of such dividend or distribution) shall be less
than 20 Trading Days, the period shall be such lesser number of Trading Days
but, in any event, not less than five Trading Days.

     (xii)  No adjustment in the Conversion Price need be made until all
cumulative adjustments amount to 1% or more of the Conversion Price as last
adjusted.  Any adjustments that are not made shall

                                       6
<PAGE>
 
be carried forward and taken into account in any subsequent adjustment.  All
calculations under this paragraph 3 shall be made to the nearest 1/10,000th of a
cent or to the nearest 1/10,000th of a share, as the case may be.

     (xiii) For purposes of this paragraph 3, "Common Stock" includes any
stock of any  class of the Company which has no preference in respect of
dividends or of amounts payable in the event of any voluntary or involuntary
liquidation, dissolution or winding-up of the Company and which is not subject
to redemption by the Company.  However, subject to the provisions of paragraph
3(xviii) below, shares issuable on conversion of shares of Preferred Stock shall
include only shares of the class designated as Common Stock of the Company on
the Preferred Stock Issue Date or shares of any class or classes resulting from
any reclassification thereof and which have no preferences in respect of
dividends or amounts payable in the event of any voluntary or involuntary
liquidation, dissolution or winding-up of the Company and which are not subject
to redemption by the Company; provided that, if at any time there shall be more
than one such resulting class, the shares of each such class then so issuable
shall be substantially in the proportion which the total number of shares of
such class resulting from all such reclassifications bears to the total number
of shares of all such classes resulting from all such reclassifications.

     (xiv)  No adjustment in the Conversion Price shall reduce the Conversion
Price below the then par value of the Common Stock.  No adjustment in the
Conversion Price need be made under paragraphs 3(vi), 3(vii) and 3(ix) above if
the Company issues or distributes to each holder of Preferred Stock the shares
of Common Stock, evidences of indebtedness, assets, rights, options or warrants
referred to in those paragraphs which each holder would have been entitled to
receive had Preferred Stock been converted into Common Stock prior to the
happening of such event or the record date with respect thereto.

     (xv)   Whenever the Conversion Price is adjusted, the Company shall
promptly mail to holders of Preferred Stock, first class, postage prepaid, a
notice of the adjustment. The Company shall file with the transfer agent for the
Preferred Stock, if any, a certificate from the Company's independent public
accountants briefly stating the facts requiring the adjustment and the manner of
computing it. Subject to paragraph 3(xvi) below, the certificate shall be
conclusive evidence that the adjustment is correct.

     (xvi)  The Company from time to time may reduce the Conversion Price if it
considers such reductions to be advisable in order that any event treated for
federal income tax purposes as a dividend of stock or stock rights will not be
taxable to the holders of Common Stock by any amount, but in no event may the
Conversion Price be less than the par value of a share of Common Stock.
Whenever the Conversion Price is reduced, the Company shall mail to holders of
Preferred Stock a notice of the reduction.  The Company shall mail, first class,
postage prepaid, the notice at least 15 days before the date the reduced
Conversion Price takes effect.  The notice shall state the reduced Conversion
Price and the period it will be in effect.  A reduction of the Conversion Price
does not change or adjust the Conversion Price otherwise in effect for purposes
of paragraphs 3(vi), 3(vii), 3(viii) and 3(ix) above.

     (xvii) If:

            (A)  the Company takes any action which would require an adjustment
in the Conversion Price pursuant to paragraph 3(vii), 3(ix) or 3(x) above;

            (B)  the Company consolidates or merges with, or transfers all or
substantially all of its assets to, another corporation, and stockholders of the
Company must approve the transaction; or

                                       7
<PAGE>
 
             (C)  there is a dissolution or liquidation of the Company;

the Company shall mail to holders of the Preferred Stock, first class, postage
prepaid, a notice stating the proposed record or effective date, as the case may
be.  The Company shall mail the notice at least 10 days before such date.
However, failure to mail the notice or any defect in it shall not affect the
validity of any transaction referred to in clause (A), (B) or (C) of this
paragraph 3(xvii).

     (xviii) In the case of any consolidation of the Company or the merger of
the Company with or into any other entity or the sale or transfer of all or
substantially all the assets of the Company pursuant to which the Company's
Common Stock is converted into other securities, cash or assets, upon
consummation of such transaction, each share of Preferred Stock shall
automatically become convertible into the kind and amount of securities, cash or
other assets receivable upon the consolidation, merger, sale or transfer by a
holder of the number of shares of Common Stock into which such share of
Preferred Stock might have been converted immediately prior to such
consolidation, merger, transfer or sale (assuming such holder of Common Stock
failed to exercise any rights of election and received per share the kind and
amount of consideration receivable per share by a plurality of non-electing
shares).  Appropriate adjustment (as determined by the Board of Directors of the
Company) shall be made in the application of the provisions herein set forth
with respect to the rights and interests thereafter of the holders of Preferred
Stock, to the end that the provisions set forth herein (including provisions
with respect to changes in and other adjustment of the Conversion Price) shall
thereafter be applicable, as nearly as reasonably may be, in relation to any
shares of stock or other securities or property thereafter deliverable upon the
conversion of Preferred Stock.  If this paragraph 3(xviii) applies, paragraphs
3(vi), 3(viii) and 3(x) do not apply.

     (xix)   In any case in which this paragraph 3 shall require that an
adjustment as a result of any event become effective from and after a record
date, the Company may elect to defer until after the occurrence of such event
the issuance to the holder of any shares of Preferred Stock converted after such
record date and before the occurrence of such event of the additional shares of
Common Stock issuable upon such conversion over and above the shares issuable on
the basis of the Conversion Price in effect immediately prior to adjustment;
provided, however, that if such event shall not have occurred and authorization
of such event shall be rescinded by the Company, the Conversion Price shall be
recomputed immediately upon such recision to the price that would have been in
effect had such event not been authorized, provided that such recision is
permitted by and effective under applicable laws.

     4.      Liquidation Rights.  Upon any voluntary or involuntary liquidation,
             ------------------                                                 
dissolution or winding-up of the Company or reduction or decrease in its capital
stock resulting in a distribution of assets to the holders of any class or
series of the Company's capital stock, each holder of shares of the Preferred
Stock will be entitled to payment out of the assets of the Company available for
distribution of an amount equal to the Liquidation Preference per share of
Preferred Stock held by such holder, plus accrued and unpaid dividends and
Liquidated Damages, if any, to the date fixed for liquidation, dissolution,
winding-up or reduction or decrease in capital stock, before any distribution is
made on any Junior Securities, including, without limitation, common stock of
the Company. After payment in full of the Liquidation Preference and all accrued
dividends and Liquidated Damages, if any, to which holders of Preferred Stock
are entitled, such holders will not be entitled to any further participation in
any distribution of assets of the Company. If, upon any voluntary or involuntary
liquidation, dissolution or winding-up of the Company, the amounts payable with
respect to the Preferred Stock and all other Parity Securities are not paid in
full, the holders of the Preferred Stock and the Parity Securities will share
equally and ratably in any distribution of assets of the Company in proportion
to the full liquidation preference and accumulated and unpaid dividends and
Liquidated Damages, if any, to which each is

                                       8
<PAGE>
 
entitled. However, neither the voluntary sale, conveyance, exchange or transfer
(for cash, shares of stock, securities or other consideration) of all or
substantially all of the property or assets of the Company nor the consolidation
or merger of the Company with or into one or more Persons will be deemed to be a
voluntary or involuntary liquidation, dissolution or winding-up of the Company
or reduction or decrease in capital stock, unless such sale, conveyance,
exchange or transfer shall be in connection with a liquidation, dissolution or
winding-up of the business of the Company or reduction or decrease in capital
stock.

     5.     Optional Redemption.

whole or in part, at the option of the Company on or after October 18, 2000, at

than 60 days' prior written notice, if redeemed during the 12-month period
commencing on October 18 of each of the years set forth below:

<TABLE>

          Year                                     Percentage
          ----                                     ----------
          <S>                                      <C>

          2004 and thereafter..............        100.00%
</TABLE> 

     No optional redemption pursuant to this paragraph 5(i) shall be authorized
or made unless, prior to giving the applicable redemption notice, all
accumulated and unpaid dividends for periods ended prior to the date of such
redemption notice shall have been paid in cash, Common Stock or a combination
thereof.

     (ii)   In case of redemption of less than all of the shares of Preferred
Stock at the time outstanding, the shares to be redeemed shall be selected pro
rata or by lot as determined by the Company in its sole discretion.

     (iii)  Notice of any redemption shall be sent by or on behalf of the
Company not less than 30 nor more than 60 days prior to the date specified for
redemption in such notice (the "Redemption Date"), by first class mail, postage
prepaid, to all holders of record of the Preferred Stock at their last addresses
as they shall appear on the books of the Company; provided, however, that no
failure to give such notice or any defect therein or in the mailing thereof
shall affect the validity of the proceedings for the redemption of any shares of
Preferred Stock except as to the holder to whom the Company has failed to give
notice or except as to the holder to whom notice was defective.  In addition to
any information required by law or by the applicable rules of any exchange upon
which Preferred Stock may be listed or admitted to trading, such notice shall
state:  (i) that such redemption is being made pursuant to the optional
redemption provisions hereof; (ii) the Redemption Date; (iii) the Applicable
Redemption Price; (iv) the number of shares of Preferred Stock to be redeemed
and, if less than all shares held by such holder are to be redeemed, the number
of such shares to be redeemed; (v) the place or places where certificates for
such shares are to be surrendered for payment of the Applicable Redemption
Price,

                                       9
<PAGE>
 
including any procedures applicable to redemptions to be accomplished through
book-entry transfers; and (vi) that dividends on the shares to be redeemed will
cease to accumulate on the Redemption Date.  Upon the mailing of any such notice
of redemption, the Company shall become obligated to redeem at the time of
redemption specified thereon all shares called for redemption.

     (iv)   If notice has been mailed in accordance with Section 5(iii) above
and provided that on or before the Redemption Date specified in such notice, all
funds necessary for such redemption shall have been set aside by the Company,
separate and apart from its other funds in trust for the pro rata benefit of the
holders of the shares so called for redemption, so as to be, and to continue to
be available therefor, then, from and after the Redemption Date, dividends on
the shares of the Preferred Stock so called for redemption shall cease to
accumulate, and said shares shall no longer be deemed to be outstanding and
shall not have the status of shares of Preferred Stock, and all rights of the
holders thereof as stockholders of the Company (except the right to receive from
the Company the Applicable Redemption Price) shall cease. Upon surrender, in
accordance with said notice, of the certificates for any shares so redeemed
(properly endorsed or assigned for transfer, if the Company shall so require and
the notice shall so state), such shares shall be redeemed by the Company at the
Applicable Redemption Price. In case fewer than all the shares represented by
any such certificate are redeemed, a new certificate or certificates shall be
issued representing the unredeemed shares without cost to the holder thereof.

     (v)    Any funds deposited with a bank or trust company for the purpose of
redeeming Preferred Stock shall be irrevocable except that:

            (a)  the Company shall be entitled to receive from such bank or
     trust company the interest or other earnings, if any, earned on any money
     so deposited in trust, and the holders of any shares redeemed shall have no
     claim to such interest or other earnings; and

            (b)  any balance of monies so deposited by the Company and unclaimed
     by the holders of the Preferred Stock entitled thereto at the expiration of
     two years from the applicable Redemption Date shall be repaid, together
     with any interest or other earnings earned thereon, to the Company, and
     after any such repayment, the holders of the shares entitled to the funds
     so repaid to the Company shall look only to the Company for payment without
     interest or other earnings.

     (vi)   No Preferred Stock may be redeemed except with funds legally
available for such purpose. The Company shall take all actions required or
permitted under the DGCL to permit any such redemption.

     (vii)  Notwithstanding the foregoing provisions of this Section 5, unless
the full cumulative dividends on all outstanding shares of Preferred Stock shall
have been paid or contemporaneously are declared and paid for all past dividend
periods, none of the shares of Preferred Stock shall be redeemed unless all
outstanding shares of Preferred Stock are simultaneously redeemed.

     6.     Change of Control.
            ----------------- 

     (i)    Subject to paragraph (6)(v) hereof, upon the occurrence of a Change
of Control, the Company shall be required to make an offer (a "Preferred Stock
Change of Control Offer") to each holder of shares of Preferred Stock to
repurchase all or any part of such holder's shares of Preferred Stock at an
offer price in cash equal to 100% of the aggregate Liquidation Preference
thereof, plus accumulated and unpaid dividends (including an amount equal to a
prorated dividend for the period from

                                      10
<PAGE>
 
the Dividend Payment Date immediately prior to the Change of Control Payment
Date) and Liquidated Damages, if any, thereon to the date of repurchase (the
"Change of Control Payment").

     (ii)   Within 30 days following any Change of Control, the Company shall
(a) publish a notice of the Change of Control in The Wall Street Journal or a
similar daily business publication of national distribution and (b) mail a
notice to each holder of Preferred Stock describing the transaction that
constitutes the Change of Control, together with such other information as may
be required pursuant to the securities laws, and stating: (A) that the Change of
Control Offer is being made pursuant to this Certificate of Designations and
that, to the extent lawful, all shares of Preferred Stock validly tendered will
be accepted for payment; (B) the purchase price and the purchase date, which
shall be no earlier than 30 days nor later than 60 days from the date such
notice is mailed (the "Change of Control Payment Date"); (C) that any shares of
Preferred Stock not tendered will continue to accrue dividends in accordance
with the terms of this Certificate of Designations; (D) that, unless the Company
defaults in the payment of the Change of Control Payment, all shares of
Preferred Stock accepted for payment pursuant to the Change of Control Offer
shall cease to accrue dividends on the Change of Control Payment Date; and (E) a
description of the procedures to be followed by such holder in order to have its
shares of Preferred Stock repurchased.

     (iii)  On the Change of Control Payment Date, the Company shall, to the
extent lawful, (A) accept for payment shares of Preferred Stock validly tendered
pursuant to the Change of Control Offer and (B) promptly mail to each holder of
shares of Preferred Stock so accepted payment in an amount equal to the purchase
price for such shares and (C) unless the Company defaults in the payment for the
shares of Preferred Stock tendered pursuant to the Preferred Stock Change of
Control Offer, dividends will cease to accrue with respect to the shares of
Preferred Stock tendered and all rights of holders of such tendered shares will
terminate, except for the right to receive payment therefor, on the Change of
Control Payment Date.  The Company shall publicly announce the results of the
Preferred Stock Change of Control Offer on or as soon as practicable after the
Change of Control Payment Date.

     (iv)   The Company shall comply with any securities laws and regulations,
to the extent such laws and regulations are applicable to the repurchase of
shares of the Preferred Stock in connection with a Change of Control.

     (v)    Notwithstanding the foregoing, prior to complying with this
paragraph 6, but in any event within 90 days following a Change of Control, the
Company shall either (a) repay or refinance all outstanding indebtedness or (b)
obtain the requisite consents, if any, under all agreements governing
outstanding indebtedness necessary to permit the repurchase of the Preferred
Stock required by this paragraph 6. The Company must first comply with the
covenants in its outstanding indebtedness or take the actions described in the
preceding sentence before it will be required to repurchase shares of Preferred
Stock in the event of a Change of Control; provided, that if the Company fails
to repurchase shares of Preferred Stock, the sole remedy to holders of Preferred
Stock will be the voting rights arising from a Voting Rights Triggering Event.
Moreover, the Company will not repurchase or redeem any Preferred Stock pursuant
to this Change of Control provision prior to the Company's repurchase of the
Series B Preferred Stock pursuant to the Change of Control covenants in the
Series B Preferred Stock and the Company's repurchase or redemption obligation
may be concurrent with analogous obligations under Parity Securities.

     (vi)   Notwithstanding the foregoing, the Company shall not be required to
make a Preferred Stock Change of Control Offer following a Change of Control if
a third party makes the Preferred Stock Change of Control Offer in the manner,
at the times and otherwise in compliance with the requirements

                                      11
<PAGE>
 
set forth in this Certificate of Designations applicable to a Preferred Stock
Change of Control Offer made by the Company and purchases all of the Preferred
Stock validly tendered and not withdrawn under such Preferred Stock Change of
Control Offer.

     7.     Voting Rights.
            ------------- 

     (i)    The holders of record of shares of the Preferred Stock shall have no
voting rights, except as required by law and as hereinafter provided in this
Section 7.

     (ii)   Upon:

            (a)  the accumulation of accrued and unpaid dividends on the
     outstanding Preferred Stock in an amount equal to six (6) quarterly
     dividends (whether or not consecutive); or

            (b)  the failure of the Company to make a Preferred Stock Change of
     Control Offer or to repurchase all of the Preferred Stock tendered in a
     Preferred Stock Change of Control Offer (each of the events described in
     clauses (a) and (b) being referred to herein as a "Voting Rights Triggering
     Event");

then the holders of a majority of the outstanding shares of Preferred Stock,
voting together with any subsequently issued Parity Securities than entitled to
voting rights, shall be entitled to elect such number of members to the Board of
Directors of the Company constituting at least 20% of the then existing Board of
Directors before such election (rounded to the nearest whole number), provided,
however, that such number shall be no less than one nor greater than two, and
the number of members of the Company's Board of Directors shall be immediately
and automatically increased by one or two, as the case may be.

     (iii)  Whenever such voting right shall have vested, such right may be
exercised initially either at a special meeting of the holders of Preferred
Stock, called as hereinafter provided, or at any annual meeting of stockholders
held for the purpose of electing directors, and thereafter at such annual
meetings or by the written consent of the holders of Preferred Stock.  Such
right of the holders of Preferred Stock to elect directors may be exercised
until (a) all dividends in arrears shall have been paid in full and (b) all
other Voting Rights Triggering Events have been cured or waived, at which time
the term of such directors previously elected shall thereupon terminate, and
such directors shall be deemed to have resigned.

     (iv)   At any time when such voting right shall have vested in the holders
of Preferred Stock and if such right shall not already have been initially
exercised, a proper officer of the Company shall, upon the written request of
holders of record of 10% or more of the Preferred Stock then outstanding,
addressed to the Secretary of the Company, call a special meeting of holders of
Preferred Stock. Such meeting shall be held at the earliest practicable date
upon the notice required for annual meetings of stockholders at the place for
holding annual meetings of stockholders of the Company or, if none, at a place
designated by the Secretary of the Company. If such meeting shall not be called
by the proper officers of the Company within 30 days after the personal service
of such written request upon the Secretary of the Company, or within 30 days
after mailing the same within the United States, by registered mail, addressed
to the Secretary of the Company at its principal office (such mailing to be
evidenced by the registry receipt issued by the postal authorities), then the
holders of record of 10% of the shares of Preferred Stock then outstanding may
designate in writing a holder of Preferred Stock to call such meeting at the
expense of the Company, and such meeting may be called by such person so
designated upon the notice required for annual meetings of stockholders and
shall be held at the place for

                                      12
<PAGE>
 
holding annual meetings of the Company or, if none, at a place designated by
such holder.  Any holder of Preferred Stock that would be entitled to vote at
such meeting shall have access to the stock books of the Company for the purpose
of causing a meeting of stockholders to be called pursuant to the provisions of
this Section 7.  Notwithstanding the provisions of this paragraph, however, no
such special meeting shall be called if any such request is received less than
90 days before the date fixed for the next ensuing annual or special meeting of
stockholders.

     (v)    If any director so elected by the holders of Preferred Stock shall
cease to serve as a director before his term shall expire, the holders of
Preferred Stock then outstanding may, at a special meeting of the holders called
as provided above, elect a successor to hold office for the unexpired term of
the director whose place shall be vacant.

     (vi)   The Company shall not, without the affirmative vote or consent of
the holders of at least a majority of the shares of Preferred Stock then
outstanding (with shares held by the Company or any of its affiliates not being
considered to be outstanding for this purpose) voting or consenting as the case
may be, as one class:

            (a)  authorize, create (by way of reclassification or otherwise) or
     issue any Senior Securities or any obligation or security convertible or
     exchangeable into or evidencing the right to purchase, shares of any class
     or series of Senior Securities;

            (b)  amend or otherwise alter this Certificate of Designation
     (including the provisions of Section 7 hereof) in any manner that adversely
     affects the specified rights, preferences, privileges or voting rights of
     holders of Preferred Stock;

            (c)  authorize the issuance of any additional shares of Preferred
     Stock; or

            (d)  waive any existing Voting Rights Triggering Event or compliance
     with any provision of this Certificate of Designation;

provided, however, that the Company shall not amend the Change of Control
provisions of this Certificate of Designation (including the related
definitions) without the approval of the holders of at least 66 2/3% of the then
outstanding shares of Preferred Stock, voting or consenting, as the case may be,
as one class.

     (vii)  Without the consent of each holder affected, an amendment or waiver
of the Company's Certificate of Incorporation or of this Certificate of
Designation may not (with respect to any shares of Preferred Stock held by a
non-consenting holder):

            (a)  alter the voting rights with respect to the Preferred Stock or
     reduce the number of shares of Preferred Stock whose holders must consent
     to an amendment, supplement or waiver;

            (b)  reduce the Liquidation Preference of or alter the provisions
     with respect to the redemption of the Preferred Stock (except as provided
     with respect to Section 6 hereof);

            (c)  reduce the rate of or change the time for payment of dividends
     on any share of Preferred Stock;

            (d)  waive the consequences of any failure to pay dividends on the
     Preferred Stock;

                                      13
<PAGE>
 
            (e)  make any share of Preferred Stock payable in any form other
     than that stated in this Certificate of Designation;

            (f)  make any change in the provisions of this Certificate of
     Designation relating to waivers of the rights of holders of Preferred Stock
     to receive the Liquidation Preference and dividends on the Preferred Stock;

            (g)  waive a redemption payment with respect to any share of
     Preferred Stock (except as provided with respect to Section 6 hereof); or

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

     (viii) The Company in its sole discretion may without the vote or consent
of any holders of the Preferred Stock amend or supplement this Certificate of
Designation:

            (a)  to cure any ambiguity, defect or inconsistency;

            (b)  to provide for uncertificated Preferred Stock in addition to or
     in place of certificated Preferred Stock; or

            (c)  to make any change that would provide any additional rights or
     benefits to the holders of the Preferred Stock or that does not adversely
     affect the legal rights under this Certificate of Designation of any such
     holder.

Except as set forth above, (x) the creation, authorization or issuance of any
shares of Junior Securities, Parity Securities or Senior Securities or (y) the
increase or decrease in the amount of authorized capital stock of any class,
including any preferred stock, shall not require the consent of the holders of
the Preferred Stock and shall not be deemed to affect adversely the rights,
preferences, privileges, special rights or voting rights of holders of shares of
Preferred Stock.

     8.     Merger, Consolidation and Sale of Assets.  Without the vote or 
            ---------------------------------------- 
consent of the holders of a majority of the then outstanding shares of Preferred
Stock, the Company may not consolidate or merge with or into, or sell, assign,
transfer, lease, convey or otherwise dispose of all or substantially all of its
assets to, any person unless (i) the entity formed by such consolidation or
merger (if other than the Company) or to which such sale, assignment, transfer,
lease, conveyance or other disposition shall have been made (in any such case,
the "resulting entity") is a corporation organized and existing under the laws
of the United States or any State thereof or the District of Columbia; (ii) if
the Company is not the resulting entity, the Preferred Stock is converted into
or exchanged for and becomes shares of such resulting entity, having in respect
of such resulting entity the same (or more favorable) powers, preferences and
relative, participating, optional or other special rights thereof that the
Preferred Stock had immediately prior to such transaction; and (iii) immediately
after giving effect to such transaction, no Voting Rights Triggering Event has
occurred and is continuing. The resulting entity of such transaction shall
thereafter be deemed to be the "Company" for all purposes of this Certificate of
Designations.

     9.     Reports.  The Company shall file within 15 days after it files them
            -------                                                            
with the Commission copies of the annual and quarterly reports and the
information, documents, and other reports that the Company is required to file
with the Commission pursuant to Section 13(a) or 15(d) of the Exchange Act ("SEC
Reports") with the Transfer Agent. In the event the Company is not required or
shall cease to be

                                      14
<PAGE>
 
required to file SEC Reports, pursuant to the Exchange Act, the Company shall
nevertheless continue to file such reports with the Commission (unless the
Commission shall not accept such a filing) and the Transfer Agent. Whether or
not required by the Exchange Act to file SEC Reports with the Commission, so
long as any shares of Preferred Stock are outstanding, the Company shall furnish
copies of the SEC Reports to the holders of Preferred Stock at the time the
Company is required to make such information available to the Transfer Agent and
any investors who request it in writing. In addition, the Company has agreed
that, for so long as any Preferred Stock remain outstanding, it will furnish to
the holders and to securities analysts and prospective investors, upon their
request, the information required to be delivered pursuant to Rule 144A(d)(4)
under the Securities Act.

     10.    Amendment.  This Certificate of Designation shall not be amended,
            ---------                                                        
either directly or indirectly, or through merger or consolidation with another
entity, in any manner that would alter or change the powers, preferences or
special rights of the Preferred Stock so as to affect them adversely without the
affirmative vote of the holders of a majority or more of the outstanding
Preferred Stock, voting separately as a class.

     11.    Exclusion of Other Rights.  Except as may otherwise be required by
            -------------------------                                         
law, the shares of Preferred Stock shall not have any voting powers, preferences
and relative, participating, optional or other special rights, other than those
specifically set forth in this resolution (as such resolution may be amended
from time to time) and in the Certificate of Incorporation.  The shares of
Preferred Stock shall have no preemptive or subscription rights.

     12.    Headings of Subdivisions.  The headings of the various subdivisions
            ------------------------                                           
hereof are for convenience of reference only and shall not affect the
interpretation of any of the provisions hereof.

     13.    Severability of Provisions.  If any voting powers, preferences and
            --------------------------                                        
relative, participating, optional and other special rights of the Preferred
Stock and qualifications, limitations and restrictions thereof set forth in this
resolution (as such resolution may be amended from time to time) is invalid,
unlawful or incapable of being enforced by reason of any rule of law or public
policy, all other voting powers, preferences and relative, participating,
optional and other special rights of Preferred Stock and qualifications,
limitations and restrictions thereof set forth in this resolution (as so
amended) which can be given effect without the invalid, unlawful or
unenforceable voting powers, preferences and relative, participating, optional
and other special rights of Preferred Stock and qualifications, limitations and
restrictions thereof shall, nevertheless, remain in full force and effect, and
no voting powers, preferences and relative, participating, optional or other
special rights of Preferred Stock and qualifications, limitations and
restrictions thereof herein set forth shall be deemed dependent upon any other
such voting powers, preferences and relative, participating, optional or other
special rights of Preferred Stock and qualifications, limitations and
restrictions thereof unless so expressed herein.

     14.    Reissuance of Preferred Stock.  Shares of Preferred Stock that have
            -----------------------------                                      
been issued and reacquired in any manner, including shares purchased or redeemed
or exchanged or converted, shall (upon compliance with any applicable provisions
of the laws of Delaware) have the status of authorized but unissued shares of
preferred stock of the Company undesignated as to series and may be designated
or redesignated and issued or reissued, as the case may be, as part of any
series of preferred stock of the Company, provided that any issuance of such
shares as Preferred Stock must be in compliance with the terms hereof.

     15.    Mutilated or Missing Preferred Stock Certificates.  If any of the
            -------------------------------------------------                
Preferred Stock certificates shall be mutilated, lost, stolen or destroyed, the
Company shall issue, in exchange and in

                                      15
<PAGE>
 
substitution for and upon cancellation of the mutilated Preferred Stock
certificate, or in lieu of and substitution for the Preferred Stock certificate
lost, stolen or destroyed, a new Preferred Stock certificate of like tenor and
representing an equivalent amount of shares of Preferred Stock, but only upon
receipt of evidence of such loss, theft or destruction of such Preferred Stock
certificate and indemnity, if requested, satisfactory to the Company and the
transfer agent (if other than the Company).

     16.    Certain Definitions.  As used in this Certificate of Designations,
            -------------------
the following terms shall have the following meanings (with terms defined in the
singular having comparable meanings when used in the plural and vice versa),
unless the context otherwise requires:

     "Business Day" means any day except a Saturday, a Sunday, or any day on
      ------------

     "Change of Control" means the occurrence of any of the following: (i) the
      -----------------                                                       
sale, lease, transfer, conveyance or other disposition (other than by way of
merger or consolidation), in one or a series of related transactions, of all or
substantially all of the assets of the Company and its subsidiaries, taken as a
whole, (ii) the adoption of a plan relating to the liquidation or dissolution of
the Company, (iii) the consummation of any transaction (including, without
limitation, any merger or consolidation) the result of which is that any
"person" or "group" (as such terms are used in Section 13(d)(3) of the Exchange
Act) becomes the "beneficial owner" (as such term is defined in Rule 13d-3 and
Rule 13d-5 under the Exchange Act), directly or indirectly through one or more
intermediaries, of more than 50% of the voting power of the outstanding voting
stock of the Company, unless (A) the closing price per share of Common Stock for
any five Trading Days within the period of ten consecutive Trading Days ending
immediately after the announcement of such Change of Control equals or exceeds
105% of the Conversion Price then in effect or (B) at least 90% of the
consideration in the transaction or transactions constituting a Change of

provided, however, that a transaction in which the Company becomes a subsidiary
of another entity shall not constitute a Change of Control if (A) the
stockholders of the Company immediately prior to such transaction "beneficially
own" (as such term is defined in Rule 13d-3 and Rule 13d-5 under the Exchange
Act), directly or indirectly through one or more intermediaries, at least a
majority of the voting power of the outstanding voting stock of the Company
immediately following the consummation of such transaction and (B) immediately
following the consummation of such transaction, no "person" or "group" (as such
terms are defined above), other than such other entity (but including holders of
equity interests of such other entity), "beneficially owns" (as such term is

the Preferred Stock to be redeemed, by first class postage prepaid, not less
than 30 and not more than 60 days prior to the date fixed for redemption of such
Preferred Stock and Depositary Shares (the "Redemption Date"), to the holders of
record on the record date for such redemption (determined pursuant to Section
4.4) of the Receipts evidencing the Depositary Shares to be so redeemed, at the
addresses of such holders as the same appear on the records of the Depositary;
but neither failure to mail any such notice to one or more such holders nor any
defect in any notice shall affect the sufficiency of the proceedings for
redemption as to other holders.  Each such notice shall state the record date
for the purposes of such redemption; the Redemption Date; the number of
Depositary Shares to be redeemed and, if less than all of the Depositary Shares
held by any such holder are to be redeemed, the number of such Depositary Shares
held by such holder to be so redeemed; the amount of cash to be received by such
holder; the place or places where Receipts evidencing Depositary Shares are to
be surrendered for cash; and that dividends in respect of the Preferred Stock
represented by the Depositary Shares to be redeemed will cease to accrue at the
close of business on such Redemption Date.  In case less than all the
outstanding Depositary Shares are to be

                                       8
<PAGE>
 
redeemed, the Depositary Shares to be so redeemed shall be selected by lot or
pro rata (as nearly as may be) or in any other equitable manner determined by
the Depositary to be consistent with the method determined by the Board of
Directors with respect to the Preferred Stock.

               (b)  Notice having been mailed by the Depositary as described in
Section 2.4(a), from and after the Redemption Date (unless the Company shall
have failed to redeem the shares of Preferred Stock to be redeemed by it as set
forth in the Company's notice provided for in Section 2.4(a)), all dividends in
respect of the shares of Preferred Stock so called for redemption shall cease to
accrue, the Depositary Shares being so redeemed shall be deemed no longer to be
outstanding, all rights of the holders of Receipts evidencing such Depositary
Shares shall cease and terminate and, upon surrender in accordance with said
notice of the Receipts evidencing any such Depositary Shares (properly endorsed
or assigned for transfer, if the Depositary shall so require), such Depositary
Shares shall be redeemed by the Depositary for the consideration therefor
specified in said notice, plus all money and other property, if any, represented
by such Depositary Shares, including all amounts, if any, paid by the Company in
respect of dividends which on the Redemption Date have accrued on the shares of
Preferred Stock to be so redeemed and have not theretofore been paid.  If less
than all of the Depositary Shares evidenced by any Receipt are called for
redemption, the Depositary will deliver to the holder of such Receipt upon its
surrender to the Depositary, together with the redemption payment, a new Receipt
evidencing the Depositary Shares evidenced by such prior Receipt and not called
for redemption.  The foregoing shall further be subject to the terms and
conditions of the Preferred Stock, as set forth in the Certificate of
Incorporation and Certificate of Designation.

               (c)  Any balance of monies deposited by the Company for the
purpose of redeeming Preferred Stock underlying the Depositary Shares and
unclaimed by the holders of the Depositary Shares entitled thereto at the
expiration of two years from the Redemption Date shall be repaid, together with
any interest or earnings thereon, if any, to the Company. After any such
repayment, such holders of Depositary Shares entitled to the funds so repaid to
the Company shall look only to the Company for payment without interest or other
earnings.

          SECTION 2.5  CONVERSION OF DEPOSITARY SHARES.  (a) The Depositary
Shares held by any holder of a Receipt or Receipts may, at the option of such
holder, be converted, in whole, or from time to time in part (but only in lots
of 100 Depositary Shares or integral multiples thereof if less then all the
Depositary Shares held by such holder are being converted), into shares of
Common Stock upon the same terms and conditions as the Preferred Stock, except
that the number of shares of Common Stock

                                       9
<PAGE>
 
received upon conversion of each Depositary Share will be equal to the number of
shares of Common Stock received upon conversion of one share of Preferred Stock
divided by 100.  Whenever a holder of a Receipt or Receipts shall elect to
convert the Depositary Shares represented by such Receipt or Receipts into
shares of Common Stock pursuant to the terms of the Preferred Stock, such holder
shall deliver to the Depositary or the Depositary's Agent the Receipt or
Receipts evidencing the Depositary Shares to be converted, together with a
written notice of conversion and an assignment of the Receipt or Receipts to the
Company or in blank, in form reasonably acceptable to the Depositary.  In
addition, if such holder surrenders such Depositary Shares for conversion during
the period from the close of business on any record date fixed pursuant to
Section 4.4 for the payment of dividends until the opening of business of the
dividend payment date corresponding to such record date (the "Dividend Payment
Date"), such Receipt or Receipts shall be accompanied by a payment in cash,
Common Stock or a combination thereof (depending on the method of payment that
the Company has chosen to pay the dividend) in an amount equal to the dividend
payable on the Dividend Payment Date, unless such Depositary Shares have been
called for redemption on a Redemption Date occurring during the period from the
close of business on such record date until the close of business on the
business day immediately following the Dividend Payment Date.  The dividend
payment with respect to Depositary Shares called for redemption on a date during
the period from the close of business on such record date to the close of
business on the business day immediately following the Dividend Payment Date
will be payable on the Dividend Payment Date to the record holder of such
Depositary Shares on such record date, notwithstanding the conversion of such
Depositary Shares after such record date and prior to the Dividend Payment Date,
and the holder converting such Depositary Shares need not include a payment of
such dividend amount upon surrender of such Depositary Shares.  Each conversion
of Depositary Shares shall be deemed to have been effected immediately before
the close of business on the date on which the requirements specified in the
preceding sentence shall have been satisfied (the "Conversion Date").

               (b)  If a holder of a Receipt elects to convert less than all of
the Depositary Shares evidenced by a Receipt, the Depositary will deliver to the
holder of the Receipt upon its surrender to the Depositary a new Receipt
evidencing the Depositary Shares evidenced by such prior Receipt and not
converted, together with a certificate for the shares of Common Stock issued
upon conversion. The foregoing shall further be subject to the terms and
conditions of the Preferred Stock, as set forth in the Certificate of
Incorporation and Certificate of Designation.

                                      10
<PAGE>
 
               (c)  No fractional shares of Common Stock will be issued upon
conversion of Depositary Shares.  If such conversion would otherwise result in a
fractional share of Common Stock being issued, the number of shares of Common
Stock to be issued upon conversion shall be rounded up to the nearest whole
share.

               (d)  From and after the Conversion Date, the Depositary Shares
being converted shall be deemed no longer to be outstanding, all dividends in
respect of the shares of Preferred Stock converted shall cease to accrue, all
rights of the holders of Receipts evidencing such Depositary Shares shall, to
the extent of such Depositary Shares, cease and terminate, except the right to
receive shares of Common Stock into which the Depositary Shares have been
converted and the right to receive any money or other property to which the
holders of such Receipts were entitled upon conversion (including all amounts,
if any, paid by the Company in respect of dividends which, on the Conversion
Date, have accrued on the shares of Preferred Stock to be converted and have not
theretofore been paid).

          SECTION 2.6    TRANSFER OF RECEIPTS.  Subject to the terms and
conditions of this Deposit Agreement, the Depositary shall make transfers on its
books from time to time of Receipts upon any surrender thereof at the
Depositary's Corporate Trust Office by the holder in person or by duly
authorized attorney, properly endorsed or accompanied by a properly executed
instrument of transfer, and duly stamped as may be required by law.  Thereupon
the Depositary shall execute a new Receipt or Receipts and deliver the same to
or upon the order of the Person entitled thereto evidencing the same aggregate
number of Depositary Shares as those evidenced by the Receipt or Receipts
surrendered.

          SECTION 2.7    COMBINATIONS AND SPLIT-UPS OF RECEIPTS.  Upon surrender
of a Receipt or Receipts at the Depositary's Corporate Trust Office or at such
other offices as it may designate for the purpose of effecting a split-up or
combination of such Receipt or Receipts, and subject to the terms and conditions
of this Deposit Agreement, the Depositary shall execute and deliver a new
Receipt or Receipts in the authorized denominations requested, evidencing the
same aggregate number of Depositary Shares evidenced by the Receipt or Receipts
surrendered.

          SECTION 2.8    SURRENDER OF RECEIPTS AND WITHDRAWAL OF PREFERRED
STOCK.  (a)  Any holder of a Receipt or Receipts representing any number of
whole shares of Preferred Stock may withdraw the Preferred Stock and all money
and other property, if any, represented thereby by surrendering such Receipt or
Receipts, at the Depositary's Corporate Trust Office or at such other offices as
the Depositary may designate for such withdrawals.  Thereafter, without
unreasonable delay, the

                                      11
<PAGE>
 
Depositary shall deliver to such holder, or to the Person or Persons designated
by such holder as hereinafter provided, the number of whole shares of Preferred
Stock and all money and other property, if any, represented by the Receipt or
Receipts so surrendered for withdrawal.  If the Receipt delivered by the holder
to the Depositary in connection with such withdrawal shall evidence a number of
Depositary Shares in excess of the number of Depositary Shares representing the
number of whole shares of Preferred Stock to be so withdrawn, the Depositary
shall at the same time, in addition to such number of whole shares of Preferred
Stock and such money and other property, if any, to be so withdrawn, deliver to
such holder, or upon his order, a new Receipt evidencing such excess number of
Depositary Shares.  In no event will fractional shares of Preferred Stock (or
cash in lieu thereof) be distributed by the Depositary.  Delivery of the
Preferred Stock and money and other property being withdrawn may be made by the
delivery of such certificates, documents of title and other instruments as the
Depositary may deem appropriate, which, if required by the Depositary, shall be
properly endorsed or accompanied by proper instruments of transfer.

               (b)  If the Preferred Stock and the money and other property
being withdrawn are to be delivered to a Person or Persons other than the Record
Holder of the Receipt or Receipts being surrendered for withdrawal of Preferred
Stock, such Record Holder shall execute and deliver to the Depositary a written
order so directing the Depositary and the Depositary may require that the
Receipt or Receipts surrendered by such holder for withdrawal of such shares of
Preferred Stock be properly endorsed in blank or accompanied by a properly
executed instrument of transfer in blank.

               (c)  Delivery of the Preferred Stock and the money and other
property, if any, represented by Receipts surrendered for withdrawal shall be
made by the Depositary at its Corporate Trust Office, except that at the
request, risk and expense of the holder that surrendered such Receipt or
Receipts, and for the account of the holder thereof, such delivery may be made
at such other place as may be designated by such holder.

          SECTION 2.9    LIMITATIONS ON EXECUTION AND DELIVERY, TRANSFER, SPLIT-
UP, COMBINATION AND SURRENDER OF RECEIPTS. (a) As a condition precedent to the
execution and delivery, transfer, split-up, combination or surrender of any
Receipt, the Depositary, or any of the Depositary's Agents, or the Company, may
require (i) payment to it of a sum sufficient for the payment (or, in the event
that the Depositary or the Company shall have made such payment, the
reimbursement to it) of any tax or other governmental charge with respect
thereto (including any such tax or charge with respect to Preferred Stock being
deposited or withdrawn), (ii) the production of proof satisfactory to it as to
the identity and genuineness of any signature and (iii)

                                      12
<PAGE>
 
compliance with such regulations, if any, as the Depositary or the Company may
establish consistent with the provisions of this Deposit Agreement.
 
               (b)  The deposit of Preferred Stock may be refused, or the
delivery of Receipts against Preferred Stock may be suspended or the transfer of
Receipts may be refused, or the transfer, split-up, combination or surrender of
outstanding Receipts may be suspended (i) during any period when the register of
Stockholders of the Company is closed, or (ii) if any such action is deemed
necessary or advisable by the Depositary, any of the Depositary's Agents or the
Company at any time or from time to time because of any requirement of law or of
any government or governmental body or commission, or under any provision of
this Deposit Agreement or, with the approval of the Company, for any other
reason.

          SECTION 2.10   LOST RECEIPTS, ETC.  In case any Receipt shall be
mutilated or destroyed or lost or stolen, the Depositary in its discretion may
execute and deliver a Receipt of like form and tenor in exchange and
substitution for such mutilated Receipt, or in lieu of and in substitution for
such destroyed, lost or stolen Receipt, upon (a) the filing by the holder
thereof with the Depositary of evidence satisfactory to the Depositary of such
destruction or loss or theft of such Receipt, of the authenticity thereof and of
his ownership thereof and (b) the furnishing of the Depositary with an indemnity
bond or other reasonable indemnification satisfactory to it.

          SECTION 2.11   CANCELLATION AND DESTRUCTION OF SURRENDERED RECEIPTS.
All Receipts surrendered to the Depositary or any Depositary's Agent shall be
cancelled by the Depositary. Except as prohibited by applicable law or
regulation, the Depositary shall, unless otherwise directed by the Company, hold
on behalf of the Company such Receipts so cancelled.


                                  ARTICLE III
          CERTAIN OBLIGATIONS OF HOLDERS OF RECEIPTS AND THE COMPANY

          SECTION 3.1    FILING PROOFS, CERTIFICATES AND OTHER INFORMATION.  Any
Person presenting Preferred Stock for deposit or any holder of a Receipt may be
required from time to time to file such proof of residence, or other matters or
other information, to execute such certificates and to make such representations
and warranties as the Depositary or the Company may reasonably deem necessary or
proper.  The Depositary or the Company may withhold the delivery or delay the
transfer, redemption or exchange of any receipt or the withdrawal of the
Preferred Stock represented by the Depositary Shares evidenced by any Receipt or
the distribution of any dividend or other distribution or the sale of any rights
or of the proceeds thereof

                                      13
<PAGE>
 
until such proof or other information is filed or such certificates are executed
or such representations and warranties are made.

          SECTION 3.2    PAYMENT OF TAXES OR OTHER GOVERNMENTAL CHARGES.  If any
tax or other governmental charge shall become payable by or on behalf of the
Depositary with respect to any Receipt evidencing Depositary Shares or with
respect to the Preferred Stock (or any fractional interest therein) represented
by such Depositary Shares, such tax (including transfer taxes, if any) or
governmental charge shall be payable by the holder of such Receipt, subject to
certain exceptions set forth in Section 5.7.  Transfer of any Receipt or any
withdrawal of Preferred Stock and all money or other property, if any,
represented by the Depositary Shares evidenced by such Receipt may be refused
until such payment is made, and any dividends, interest payments or other
distributions may be withheld, or any part or all of the Preferred Stock or
other property represented by the Depositary Shares evidenced by such Receipt
and not theretofore sold may be sold for the account of the holder thereof
(after attempting by reasonable means to notify such holder prior to such sale),
and such dividends, interest payments or other distributions or the proceeds of
any such sale may be applied to any payment of such tax or other governmental
charge, the holder of such Receipt remaining liable for any deficiency.

          SECTION 3.3    REPRESENTATIONS AND WARRANTIES AS TO PREFERRED STOCK.
In the case of the initial deposit of the Preferred Stock, the Company and, in
the case of subsequent deposits thereof, each Person so depositing Preferred
Stock under this Deposit Agreement shall be deemed thereby to represent and
warrant that such Preferred Stock and each certificate therefore are valid and
that the Person making such deposit is duly authorized so to do.  The Company
hereby further represents and warrants that the Preferred Stock, when issued,
will be validly issued, fully paid and nonassessable.  Such representations and
warranties shall survive the deposit of the Preferred Stock and the issuance of
Receipts.


                                  ARTICLE IV
                       THE DEPOSITED SECURITIES; NOTICES

          SECTION 4.1    CASH DISTRIBUTIONS.  Whenever the Depositary shall
receive any cash dividend or other cash distribution on Preferred Stock, the
Depositary shall, subject to Section 3.2, distribute to Record Holders of
Receipts on the record date fixed pursuant to Section 4.4 such amounts of such
sum as are, as nearly as practicable, in proportion to the respective numbers of
Depositary Shares evidenced by the Receipts held by such holders; provided,
                                                                  -------- 
however, that in case the Company or the Depositary shall be required to
- -------                                                                 
withhold and does withhold

                                      14
<PAGE>
 
from any cash dividend or other cash distribution in respect of the Preferred
Stock an amount on account of taxes, the amount made available for distribution
or distributed in respect of Depositary Shares shall be reduced accordingly.
The Depositary shall distribute or make available for distribution, as the case
may be, only such amount, however, as can be distributed without attributing to
any owner of Depositary Shares a fraction of one cent, and any balance not so
distributable shall be held by the Depositary (without liability for interest
thereon) and shall be added to and be treated as part of the next sum received
by the Depositary for distribution to Record Holders of Receipts then
outstanding.

          SECTION 4.2    DISTRIBUTIONS OTHER THAN CASH.  Whenever the Depositary
shall receive any distribution upon the Preferred Stock in shares of Common
Stock, the Depositary shall, subject to Section 3.2, distribute to Record
Holders of Receipts on the record date fixed pursuant to Section 4.4, such
shares of Common Stock received by it in proportion to the respective numbers of
Depositary Shares evidenced by the Receipts held by such holders, except that
the Depositary may not distribute fractional shares of Common Stock.  If in the
opinion of the Company, after consultation with the Depositary, such
distribution cannot be made proportionately among such Record Holders, or if for
any reason (including any requirement that the Company or the Depositary
withhold an amount on account of taxes) the Depositary deems, after consultation
with the Company, such distribution not to be feasible, the Depositary may, at
the direction of the Company, adopt such method as the Company deems equitable
and practicable for the purpose of effecting such distribution, including the
sale at public sale of the other securities or property thus received, or any
part thereof, at such place or places and upon such terms as it may deem proper.
No fractional shares of Common Stock will be issued as a distribution on the
Preferred Stock and, if such distribution would otherwise result in a fractional
share of Common Stock being issued, the Depositary shall sell the total number
of shares of Common Stock that would have been represented by such fractional
shares at public sale at such place or places and upon such terms it deems
proper.  The net proceeds of any sale made pursuant to this Section 4.2 shall,
subject to Section 3.2, be distributed or made available for distribution, as
the case may be, by the Depositary to Record Holders of Receipts as provided by
Section 4.1 in the case of a distribution received in cash.

          SECTION 4.3    SUBSCRIPTION RIGHTS, PREFERENCES OR PRIVILEGES.  (a) If
the Company shall at any time offer or cause to be offered to the Persons in
whose names Preferred Stock is recorded on the books of the Company any rights,
preferences or privileges to subscribe for or to purchase any securities or any
rights, preferences or privileges of any other nature, such rights, preferences
or privileges shall in each such instance be

                                      15
<PAGE>
 
made available by the Depositary to the Record Holders of Receipts in such
manner as the Company may determine, either by the issue to such record holders
of warrants representing such rights, preferences or privileges or by such other
method as may be approved by the Company in its discretion with the approval of
the Depositary; provided, however, that (a) if at the time of issue or offer of
                --------  -------                                              
any such rights, preferences or privileges the Company determines that it is not
lawful or (after consultation with the Depositary) not feasible to make such
rights, preferences or privileges available to holders of Receipts by the issue
of warrants or otherwise or (b) if and to the extent so instructed by holders of
Receipts who do not desire to exercise such rights, preferences or privileges,
then the Company, in its discretion (with the approval of the Depositary, in any
case where the Company has determined that it is not feasible to make such
rights, preferences or privileges available), may, if applicable laws or the
terms of such rights, preferences or privileges permit such transfer, sell such
rights, preferences or privileges at public sale, at such place or places and
upon such terms as it may deem proper.  The net proceeds of any such sale shall
be distributed by the Depositary to the Record Holders of Receipts entitled
thereto as provided by Section 4.1 in the case of a distribution received in
cash.

               (b)  If registration under the Securities Act of 1933 of the
securities to which any rights, preferences or privileges relate is required in
order for holders of Receipts to be offered or sold the securities to which such
rights, preferences or privileges relate, the Company agrees with the Depositary
that it will promptly file a registration statement pursuant to such Act with
respect to such rights, preferences or privileges and securities and use its
best efforts and take all steps available to it to cause such registration
statement to become effective sufficiently in advance of the expiration of such
rights, preferences or privileges. In no event shall the Depositary make
available to the holders of Receipts any right, preference or privilege to
subscribe for or to purchase any securities unless and until the Company
provides to the Depositary an opinion of counsel stating that the securities to
which such rights, preferences or privileges relate have been registered under
the Securities Act of 1933 or do not need to be registered under such Act.

               (c)  If any other action under the laws of any jurisdiction or
any governmental or administrative authorization, consent or permit is required
in order for such rights, preferences or privileges to be made available to
holders of Receipts, the Company agrees with the Depositary that the Company
will use its best efforts to take such action or obtain such authorization,
consent or permit sufficiently in advance of the expiration of such rights,
preferences or privileges to enable such holders to exercise such rights,
preferences or privileges.

                                      16
<PAGE>
 
          SECTION 4.4    NOTICE OF DIVIDENDS; FIXING OF RECORD DATE FOR HOLDERS
OF RECEIPTS.  Whenever (a) any cash dividend or other cash distribution shall
become payable or any distribution other than cash shall be made, or any rights,
preferences or privileges shall at any time be offered, with respect to
Preferred Stock, or (b) the Depositary shall receive notice of any meeting at
which holders of Preferred Stock are entitled to vote or of which holders of
Preferred Stock are entitled to notice or of any election on the part of the
Company to redeem any shares of Preferred Stock, the Depositary shall in each
such instance fix a record date (which shall be the same date as the record date
fixed by the Company with respect to the Preferred Stock) for the determination
of the holders of Receipts (x) who shall be entitled to receive such dividend,
distribution, rights, preferences or privileges or the net proceeds of the sale
thereof, or (y) who shall be entitled to give instructions for the exercise of
voting rights at any such meeting, or who shall be entitled to notice of such
meeting, or (z) whose Depositary Shares are to be redeemed.

          SECTION 4.5    VOTING RIGHTS.  Upon receipt of notice of any meeting
at which the holders of Preferred Stock are entitled to vote, the Depositary
shall, as soon as practicable thereafter, mail to the Record Holders of Receipts
a notice which shall contain (a) such information as is contained in such notice
of meeting, and (b) a statement that the holders of Receipts at the close of
business on a specified record date determined pursuant to Section 4.4 will be
entitled, subject to any applicable provision of law and of the Certificate of
Incorporation or the Authorizing Resolution, to instruct the Depositary as to
the exercise of the voting rights pertaining to the amount of Preferred Stock
represented by their respective Depositary Shares, and a brief statement as to
the manner in which such instructions may be given. Upon the written request of
a holder of a Receipt on such record date, the Depositary shall endeavor insofar
as practicable to vote or cause to be voted the amount of Preferred Stock
represented by the Depositary Shares evidenced by such Receipt in accordance
with the instructions set forth in such request. To the extent any such
instructions request the voting of a fraction of a share of Preferred Stock, the
Depositary shall aggregate such fraction with all other fractions resulting from
requests with the same voting instructions and shall vote the number of whole
shares resulting from such aggregation in accordance with the instructions
received in such requests. The Company hereby agrees to take all reasonable
action which may be deemed necessary by the Depositary in order to enable the
Depositary to vote such Preferred Stock or cause such Preferred Stock to be
voted. In the absence of specific written instructions from the holder of a
Receipt, the Depositary will abstain from voting to the extent of the Preferred
Stock represented by the Depositary Shares evidenced by such Receipt.

                                      17
<PAGE>
 
          SECTION 4.6    CHANGES AFFECTING DEPOSITED SECURITIES AND
RECLASSIFICATIONS, RECAPITALIZATIONS, ETC.  Upon any change in par or stated
value, split-up, consolidation or any other reclassification of the Preferred
Stock, or upon any recapitalization, reorganization, merger, amalgamation or
consolidation or sale of all or substantially all of the Company's assets
affecting the Company or to which it is a party, the Depositary shall, upon the
instructions of the Company and in such manner as the Company may deem
equitable, (a) make such adjustments in (i) the fraction of an interest
represented by one Depositary Share in one share of Preferred Stock and (ii) the
ratio of the redemption price per Depositary Share to the redemption price of a
share of Preferred Stock in each case as may be necessary to fully reflect the
effects of such change in par or stated value, split-up, consolidation or other
reclassification of the Preferred Stock, or of such recapitalization,
reorganization, merger, amalgamation or such consolidation or sale and (b) treat
any securities which shall be received by the Depositary in exchange for or upon
conversion of or otherwise in respect of the Preferred Stock as new deposited
securities under this Deposit Agreement, and Receipts then outstanding shall
thenceforth represent the new deposited securities so received.  In any such
case the Company may in its discretion, direct the Depositary to execute and
deliver additional Receipts, or may call for the surrender of all outstanding
Receipts to be exchanged for new Receipts specifically describing such new
deposited securities.

          SECTION 4.7    REPORTS.  The Depositary shall make available for
inspection by holders of Receipts at its Corporate Trust Office, and at such
other places as it may from time to time deem advisable, any reports and
communications received from the Company which are received by the Depositary as
the holder of Preferred Stock unless at the time of or prior to receipt the
Company advises the Depositary that such reports or communications have not been
generally available to the holders of Preferred Stock.

          SECTION 4.8    LISTS OF RECEIPT HOLDERS. Upon request from time to
time by the Company, the Depositary shall, without unreasonable delay, furnish
to the Company a list, as of a recent date, of the names, addresses and holdings
of Preferred Stock by all Persons in whose names Receipts are registered on the
books of the Depositary.


                                   ARTICLE V
                        THE DEPOSITARY AND THE COMPANY

          SECTION 5.1    MAINTENANCE OF OFFICE, AGENCIES, TRANSFER BOOKS BY THE
DEPOSITARY REGISTRAR.  (a) Upon execution of this Deposit Agreement in
accordance with its terms, the

                                      18
<PAGE>
 
Depositary shall maintain at its Corporate Trust Office facilities for the
execution and delivery, transfer, surrender and exchange of Receipts, and at the
offices of the Depositary's Agents, if any, facilities for the delivery,
transfer, surrender and exchange of Receipts, all in accordance with the
provisions of this Deposit Agreement.

               (b)  The Depositary shall keep books at its Corporate Trust
Office for the transfer of Receipts, which books at all reasonable times shall
be open for inspection by the Record Holders of Receipts, unless the Company
advises the Depositary in a particular instance that such inspection is not for
a proper purpose reasonably related to such Person's interest as an owner of
Depositary Shares evidenced by the Receipts. The Depositary may close such
books, at any time or from time to time, when deemed expedient by it in
connection with the performance of its duties hereunder.

               (c)  If the Receipts or the Depositary Shares evidenced thereby
or the Preferred Stock represented by such Depositary Shares shall be quoted on
the Nasdaq National Market, the Company may, upon consultation with the
Depositary, appoint a Registrar for registry of such Receipts or Depositary
Shares in accordance with the requirements of the Nasdaq National Market. Such
Registrar (which may be the Depositary if so permitted by the requirements of
the Nasdaq National Market) may be removed and a substitute registrar appointed
by the Depositary upon the request or with the approval of the Company. If the
Receipts of such Depositary Shares or such Preferred Stock are listed on one or
more stock exchanges, the Depositary will, at the request of the Company,
arrange such facilities for the delivery, transfer, surrender and exchange of
such Receipts or such Depositary Share or such Preferred Stock as may be
required by law or applicable stock exchange regulation.

          SECTION 5.2    PREVENTION OR DELAY IN PERFORMANCE BY THE DEPOSITARY,
THE DEPOSITARY'S AGENTS OR THE COMPANY.  Neither the Depositary nor any
Depositary's Agent nor the Company shall incur any liability to any holder of
any Receipt, if by reason of any provision of any present or future law, or
regulation thereunder of the United States of America, or of any other
governmental authority or, in the case of the Depositary or the Depositary's
Agent, by reason of any provision, present or future, of the Certificate of
Incorporation or the Authorizing Resolution or by reason of any act of God or
war or other circumstance beyond the control of the relevant party, the
Depositary, any Depositary's Agent or the Company shall be prevented or
forbidden from or delayed in doing or performing any act or thing which the
terms of this Deposit Agreement provide shall or may be done or performed, or by
reason of any exercise of, or failure to exercise, any discretion provided for
in this Deposit Agreement.

          SECTION 5.3    OBLIGATIONS OF THE DEPOSITARY, THE DEPOSITARY'S AGENTS
AND THE COMPANY.  (a) Neither the Depositary nor any Depositary's Agent nor the
Company assumes any obligations or shall be subject to any liability under this
Deposit Agreement to holders of Receipts other than that each of them agrees to
use its best judgment and good faith in the performance of such duties as are
specifically set forth in this Deposit Agreement.

               (b)  Neither the Depositary nor any Depositary's Agent nor the
Company shall be under any obligation to appear in, prosecute or defend any
action, suit or other proceeding with respect to Preferred Stock, Depositary
Shares or Receipts, which in its opinion may involve it in expense or liability,
unless indemnity satisfactory to it against all expense and liability be
furnished as often as may be required.

               (c)  Neither the Depositary nor any Depositary's Agent nor the
Company shall be liable for any action or any failure to act by it in reliance
upon the advice of or information from legal counsel, accountants, any Person
presenting Preferred Stock for deposit, any holder of a Receipt or any other
Person believed by it in good faith to be competent to give such advice or
information. The Depositary, any Depositary's Agent and the Company may each
rely and shall each be protected in acting upon any written notice, request,
direction or other document believed by it to be genuine and to have been signed
or presented by the proper party or parties.

               (d)  The Depositary and the Depositary's Agents may own and deal
in any class of securities of the Company and its affiliates and in Receipts.

securities of the Company and its affiliates.

          SECTION 5.4    RESIGNATION AND REMOVAL OF THE DEPOSITARY, APPOINTMENT
OF SUCCESSOR DEPOSITARY.  (a) The Depositary may at any time resign as

Company, such resignation to take effect upon the appointment of a successor
depositary and its acceptance of such appointment as hereinafter provided.

               (b)  The Depositary may at any time be removed by the Company by
notice of such removal delivered to the Depositary, such removal to take effect

resign or be removed, the Company shall, within 45 days after the delivery of
the notice of resignation or

                                      20
<PAGE>
 
removal, as the case may be, appoint a successor depositary, which shall be a
bank or trust company having its principal office in the United States of
America.  Each successor depositary shall execute and deliver to its predecessor
and to the Company an instrument in writing accepting its appointment hereunder,
and thereupon such successor depositary, without any further act or deed, shall
become fully vested with all the rights, powers, duties and obligations of its
predecessor and for all purposes shall be the Depositary under this Deposit
Agreement, and such predecessor, upon payment of all sums due it and on the
written request of the Company, shall promptly execute and deliver an instrument
transferring to such successor all rights and powers of such predecessor
hereunder, shall duly assign, transfer and deliver all rights, title and
interest in the stock and any moneys or property held hereunder to such
successor, and shall deliver to such successor a list of the Record Holders of
all outstanding Receipts.  Any successor depositary shall promptly mail notice
of its appointment to the Record Holders of Receipts.

               (d)  Any corporation into or with which the Depositary may be
merged, consolidated or converted shall be the successor of such Depositary
without the execution or filing of any document or any further act. Such
successor depositary may authenticate the Receipts in the name of the
predecessor depositary or in the name of the successor depositary.

          SECTION 5.5    CORPORATE NOTICES AND REPORTS.  The Company agrees that
it will deliver to the Depositary, and the Depositary will, promptly after
receipt thereof, transmit to the Record Holders of Receipts, in each case at the
address recorded in the Depositary's books, copies of all notices and reports
(including, without limitation, financial statements) required by law, by the
rules of any national securities exchange or the Nasdaq National Market upon
which the Preferred Stock, the Depositary Shares or the Receipts are listed or
by the Certificate of Incorporation and the Authorizing Resolution to be
furnished by the Company to holders of Preferred Stock.  Such transmission will
be at the Company's expense and the Company will provide the Depositary with
such number of copies of such documents as the Depositary may reasonably
request.  In addition, the Depositary will transmit to the holders of Receipts
(at the Company's expense) such other documents as may be requested by the
Company.

          SECTION 5.6    INDEMNIFICATION BY THE COMPANY.  (a) The Company agrees
to indemnify the Depositary and its directors, employees and agents (including
any Depositary's Agent and any Registrar) against, and hold each of them
harmless from, any loss, liability or expense (including reasonable costs of
investigation, court costs, and attorneys' fees and disbursements) which may
arise out of acts performed or omitted

                                      21
<PAGE>
 
in accordance with the provisions of this Deposit Agreement, as the same may be
amended, modified or supplemented from time to time, and of the Receipts (i) by
the Depositary, and Registrar or any of their respective officers, employees or
agents (including any Depositary's Agent), except for any loss, liability or
expense arising out of negligence, bad faith or willful misconduct on the part
of any such Person or Persons, or (ii) by the Company or any of its agents.

          (b)  Any Person seeking indemnification hereunder (an "indemnified
person") shall notify the Company of the commencement of any indemnifiable
action or claim promptly after such indemnified person becomes aware of such
commencement (provided that the failure to make such notification shall not
affect such indemnified person's rights otherwise than under this Section 5.6)
and shall consult in good faith with the Company as to the conduct of the
defense of such action or claim, which shall be reasonable in the circumstances.
No indemnified person shall compromise or settle any action or claim without the
consent of the Company, which consent shall not be unreasonably withheld.

          (c)  The obligations provided in this Section 5.6 shall survive the
termination of this Deposit Agreement and the succession or substitution of any
person indemnified hereby.

          SECTION 5.7    CHARGES AND EXPENSES.  The Company shall pay all
transfer and other taxes and governmental charges arising solely from the
existence of the depositary arrangements.  The Company shall pay any and all
fees of the Depositary as shall be agreed to between the Company and the
Depositary, and all charges of the Depositary in connection with the initial
deposit of the Preferred Stock and the initial issuance of the Depositary
Receipts, distribution of information to the holders of Receipts with respect to
matters on which holders of Preferred Stock are entitled to vote, withdrawals of
the Preferred Stock by holders of the Receipts and any redemption or conversion
of the Depositary Receipts.  All other transfer and other taxes and governmental
charges shall be at the expense of holders of Depositary Shares.  If, at the
request of a holder of Receipts, the Depositary incurs charges or expenses for
which it is not otherwise liable hereunder, such holder will be liable for such
charges and expenses.  All other reasonable charges and expenses of the
Depositary and any Depositary's Agent hereunder and of any Registrar (including,
in each case, reasonable fees and expenses of counsel) incident to the
performance of their respective obligations hereunder will be paid upon
consultation and agreement between the Depositary and the Company as to the
amount and nature of such charges and expenses.  The Depositary shall present
its statement for charges and expenses to the Company monthly or at such other
intervals as the Company and the Depositary may agree.

                           AMENDMENT AND TERMINATION

          SECTION 6.1    AMENDMENT.  The form of the Receipts and any provision
of this Deposit Agreement may at any time and from time to time be amended by
agreement between the Company and the Depositary in any respect which they may
deem necessary or desirable.  Any amendment which shall impose any fees, taxes
or charges (other than fees and charges provided for herein), or which shall
otherwise prejudice any substantial existing right of holders of Receipts, shall
not become effective as to outstanding Receipts until the expiration of 90 days
after notice of such amendment shall have been given to the Record Holders of
outstanding Receipts.  Every holder of an outstanding Receipt at the time any
such amendment so becomes effective shall be deemed, by continuing to hold such
Receipt, to consent and agree to such amendment and to be bound by this Deposit
Agreement as amended thereby.  In no event shall any amendment impair the right,
subject to the provisions of Sections 2.8 and 2.9 and Article III, of any owner
of any Receipts to instruct the Depositary to deliver to the holder of Receipts
representing whole shares of Preferred Stock the whole shares of Preferred Stock
represented by such Receipts and all money and other property, if any,
represented by such Receipts, except in order to comply with mandatory
provisions of applicable law.

          SECTION 6.2    TERMINATION.  (a) Whenever so directed by the Company,
the Depositary will terminate this Deposit Agreement by mailing notice of such
termination to the Record Holders of all Receipts then outstanding at least 30
days prior to the date fixed in such notice for such termination.  The
Depositary may likewise terminate this Deposit Agreement if at any time 45 days
shall have expired after the Depositary shall have delivered to the Company
written notice of its election to resign and a successor depositary shall not
have been appointed and accepted its appointment as provided in Section 5.4.

               (b)  If any Receipts shall remain outstanding after the date of
termination of this Deposit Agreement, the Depository thereafter shall
discontinue the transfer of Receipts, shall suspend the distribution of
dividends to the holders thereof, and shall not give any further notices (other
than notice of such termination) or perform any further acts under this Deposit
Agreement, except that the Depositary shall continue to (i) collect dividends
and other distributions pertaining to the Preferred Stock, (ii) sell rights,
preferences or privileges as provided in this Deposit Agreement, and (iii)
deliver the Preferred Stock and any money and other property, without liability
for interest thereon, represented by Receipts upon surrender thereof by the
holders thereof.  At any time after the expiration of two years from the date of
termination, the

                                      23
<PAGE>
 
Depositary shall sell the Preferred Stock then held hereunder at public or
private sale, at such places and upon such terms as the Depositary deems proper
and may thereafter hold the net proceeds of any such sale, together with any
money and other property held by it hereunder, without liability for interest,
for the benefit, pro rata in accordance with their holdings, of the holders of
Receipts which have not theretofore been surrendered.  After making such sale,
the Depositary shall be discharged from all obligations under this Deposit
Agreement, except to account for such net proceeds and money and other property.
Upon the termination of this Deposit Agreement, the Company shall be discharged
from all obligations under this Deposit Agreement except for its obligations to
the Depositary, any Depositary's Agent and any Registrar under Sections 5.6 and
5.7.

                      INTERMEDIA COMMUNICATIONS COMPLETES
                         CONCURRENT PRIVATE OFFERINGS


TAMPA, FL (October 31, 1997) - Intermedia Communications Inc. (Nasdaq/NM:
ICIX) today announced the completion of two concurrent private offerings of
its securities. The Company sold 7,000,000 Depositary Shares with a $175
million liquidation preference, and $250 million principal amount of Senior
Notes, resulting in gross proceeds to the Company of $425 million.

          Each of the 7,000,000 Depositary Shares represents a one-hundredth 
interest in a share of 7% Series E Junior Convertible Preferred Stock, 
liquidation preference $2,500 per share (equivalent to $25.00 per Depositary 
Share) of Intermedia Communications Inc. Dividends on the Series E Preferred 
Stock will accrue at a rate per annum equal to 7% of the liquidation preference 
per share of Series E Preferred Stock and will be payable in cash or, at the 
option of the Company, in shares of Common Stock or a combination thereof. The 
Depositary Shares will be convertible, subject to prior redemption, at any time 
after December 29, 1997, at the option of the holder thereof into the Company's 
Common Stock at a conversion price of $60.47, subject to certain adjustments.

           The 8 7/8% Senior Notes are due on November 1, 2007, with interest 
accruing from October 30, 1997, and payable semi-annually in arrears on May 1
and November 1 of each year commencing May 1, 1998. The Notes will be
redeemable, at the option of Intermedia, in whole or in part, on or after
November 1, 2002, and are ranked pari pasu with all other senior indebtedness.

     The net proceeds from the offering of the Depositary Shares will be used by
the Company to finance the continued expansion of the Company's 
telecommunications networks, including but not limited to, network electronics, 
such as local/long distance voice and data switches, and for general corporate 
purposes, including working capital. The net proceeds from the offering of the 
Senior Notes will be used to fund up to 80% of the cost of acquisition or 
construction by the Company of telecommunications-related assets. A portion of 
the Company's expansion may occur through acquisitions (utilizing cash or 
securities of the Company) as an alternative to direct investments in the assets
required to implement the expansion.
