                                  RISK FACTORS

               Prospective investors should consider carefully the following
     factors relating to the business of the Company and this offering, in
     addition to other information set forth elsewhere in this Prospectus,
     before purchasing the Securities offered hereby.

               Limited Operations of Certain Services; History of Net Losses.
     The Company's business commenced in 1987. Substantially all of the
     Company's revenues are derived from local exchange services, enhanced data
     services, long distance services, integration services and certain local
     network services. Many of these services have only recently been initiated
     or their availability only recently expanded in new market areas. The
     Company is expecting to substantially increase the size of its operations
     in the near future. Prospective investors, therefore, have limited
     historical financial information about the Company upon which to base an
     evaluation of the Company's performance. Given the Company's limited
     operating history, there is no assurance that it will be able to compete
     successfully in the telecommunications business.

               The development of the Company's business and the expansion of
     its networks requires significant capital, operational and administrative
     expenditures, a substantial portion of which are incurred before the
     realization of revenues. These capital expenditures will result in negative
     cash flow until an adequate customer base is established. Although its
     revenues have increased in each of the last three years, Intermedia has
     incurred significant increases in expenses associated with the installation
     of local/long distance voice switches and expansion of its fiber optic
     networks, services and customer base. Intermedia reported net losses of
     approximately $3.1 million, $20.7 million, $57.2 million for the years
     ended December 31, 1994, 1995 and 1996 and a net loss of $201.2 million for
     the nine months ended September 30, 1997, respectively. The Company
     anticipates recording a significant net loss in 1997 that is expected to be
     substantially greater than the loss in 1996 and expects net losses to
     continue for the next several years. In addition, the Company expects to
     have negative EBITDA in 1997. There can be no assurance that Intermedia
     will achieve or sustain profitability or positive EBITDA in the future.

               Substantial Indebtedness; Insufficiency of Earnings to Cover
     Fixed Charges. The Company is highly leveraged. At September 30, 1997,
     after giving pro forma effect to the pending acquisition of 100% of the
     outstanding equity of Shared Technologies (the "Shared Technologies
     Acquisition"), the offering (the "October 30 Offerings") of the Company's
     7% Junior Convertible Series E Preferred Stock (the "Series E Preferred
     Stock") and the Company's 8 7/8% Senior Notes due 2007 (the "8 7/8%
     Notes"), and the offering (the "December 23 Offering") of the Company's 8
     1/2% Senior Notes due 2008 (the "8 1/2% Notes)  and the application of the
     net proceeds therefrom, the Company would have had outstanding
     approximately $1.4 billion in aggregate principal amount of indebtedness
     and other liabilities on a consolidated basis (including trade payables),
     approximately $312.0 million of obligations with respect to dividend
     payments and the mandatory redemption of the 13 1/2% Series B Redeemable
     Exchangeable Preferred Stock due 2009 (the "Series B Preferred Stock"), and
     $170.1 and $193.7 million of obligations with respect to the Company's 7%
     Junior Convertible Series D Preferred Stock (the "Series D Preferred
     Stock") and the Series E Preferred Stock, respectively. The degree to which
     the Company is leveraged could have important consequences to holders of
     the Securities, including the following: (i) a substantial portion of the
     Company's cash flow from operations will be dedicated to payment of the
     principal and interest on its indebtedness, to payment of dividends on and
     the redemption of the Series B Preferred Stock and the payment of dividends
     on the Series D Preferred Stock and the Series E Preferred Stock, thereby
     reducing funds available for other purposes; (ii) the Company's significant
     degree of leverage could increase its vulnerability to changes in general
     economic conditions or increases in prevailing interest rates; (iii) the
     Company's ability to obtain additional financing for working capital,
     capital expenditures, acquisitions, general corporate purposes or other
     purposes could be impaired; and (iv) the Company may be more leveraged than
     certain of its competitors, which may be a competitive disadvantage.

               The Company's historical earnings have been insufficient to cover
     combined fixed charges and dividends on preferred stock by $0.6 million,
     $2.3 million, $3.3 million, $19.8 million and $60.0 million for each of the
     years ended December 31, 1992, 1993, 1994, 1995 and 1996, respectively. In
     addition, insufficiencies of $37.6 million and $187.0 million were
     experienced in the nine-month periods ended September 30, 1996 and 1997,
     respectively. On a pro forma basis, after giving applicable effect to the
     DIGEX, EMI Communications, Inc. ("EMI"), Universal Telecom Inc. ("UTT") and
     Net Solve Incorporated ("NetSolve") acquisitions, the pending acquisition
     of Shared Technologies, the March 1997 sale of $300 million of preferred
     stock (the "March 1997 Offerings"), the concurrent offerings (the "July 9
     Offerings") of the Series D Preferred Stock and the Company's 11 1/4%
     Senior Discount Notes due 2007 (the 11 1/4% Notes), the October 30
     Offerings and the December 23 Offering, the Company's earnings were
     insufficient to cover combined fixed charges and dividends on preferred
     stock by $274.0 million for the year ended December 31, 1996 and by $321.1
     million for the nine months ended September 30, 1997. The Company
     anticipates that earnings will be insufficient to cover fixed charges for
     the next several years. In order for the Company to meet its debt service
     obligations, its dividend and redemption obligations with respect to the
     Series B Preferred Stock and its dividend obligations with respect to the
     Series D Preferred Stock and Series E Preferred Stock the Company will need
     to substantially improve its operating results. There can be no assurance
     that the Company's operating results will be of sufficient magnitude to
     enable the Company to meet such debt service, dividend and redemption
     obligations. In the absence of such operating results, the Company could
     face substantial liquidity problems and might be required to raise
     additional financing through the issuance of debt or equity securities;
     however, there can be no assurance that Intermedia would be successful in
     raising such financing, or the terms or timing thereof.

               Effect of Substantial Additional Indebtedness on the Company's
     Ability to Make Payments on the Securities. The indenture governing the 12
     1/2% Notes (the "12 1/2% Notes Indenture"), the indenture governing the 11
     1/4% Notes (the "11 1/4% Notes Indenture"), the indenture governing the 8
     7/8% Notes (the "8 7/8% Notes Indenture") and the indenture governing the
     Company's 8 1/2% Notes (the "8 1/2% Notes Indenture"; the 12 1/2% Notes
     Indenture,  11 1/4% Notes Indenture, 8 7/8% Notes Indenture and 8 1/2%
     Notes Indenture collectively referred to as the "Existing Indentures") and
     the Certificate of Designation governing the Series B Preferred Stock (the
     "Series B Certificate of Designation")) limit, but do not prohibit, the
     incurrence of additional indebtedness by the Company and its subsidiaries,
     and the Company may incur substantial additional indebtedness during the
     next few years to finance the construction of networks and purchase of
     network electronics, including local/long distance voice and data switches.
     In addition, the Company may establish a bank credit facility which may be
     secured by a substantial portion of the assets of the Company.  All
     additional indebtedness of the Company, including any indebtedness under a
     bank credit facility may rank pari passu with or senior in right of payment
     to any payment obligations with respect to the Securities. The debt service
     requirements of any additional indebtedness would make it more difficult
     for the Company to pay cash dividends and principal and interest with
     respect to existing securities and indebtedness of the Company as well as
     any Securities.

               Risks Associated with Acquisitions.   The Company intends to use
     the net proceeds of the October 30 Offerings and the December 23 Offering,
     to expand its networks and service offerings through internal development
     and acquisitions. On November 20, 1997, Intermedia, Moonlight Acquisition
     Corp., a wholly-owned subsidiary of Intermedia, and Shared Technologies
     signed a definitive merger agreement pursuant to which holders of Shared
     Technologies' common stock would receive $15.00 per share in cash upon
     consummation of the merger. In connection with the pending acquisition of
     Shared Technologies and in anticipation of Shared Technologies becoming a
     "Restricted Subsidiary" within the meaning of the Company's Existing
     Indentures and the Series B Certificate of Designation, the Company
     purchased certain equity interests and certain notes issued by Shared
     Technologies.  If the pending acquisition of Shared Technologies is not
     consummated before May 11, 1998 and, as a result, Shared Technologies does
     not become a Restricted Subsidiary of the Company, an Event of Default may
     occur under the terms of each of the Existing Indentures and the Series B
     Certificate of Designation unless the Company disposes of its investment in
     Shared Technologies without a loss or holds its investment through an
     Unrestricted Subsidiary.  If such an event of default occurs, upon receipt
     of notice from

                                       6
<PAGE>
 
     the trustee under any of the Existing Indentures, or the holders of at
     least 25% of the outstanding principal amounts of the 12 1/2% Notes, the 11
     1/4% Notes, the 8 7/8% Notes or the 8 1/2% Notes, acceleration of the 12
     1/2% Notes, the 11 1/4% Notes, the 8 7/8% Notes or the 8 1/2% Notes,
     respectively, would result.  The occurrence of an Event of Default would
     not lead to the acceleration of the Series B Preferred Stock.  If all of
     the 12 1/2% Notes, 11 1/4% Notes, 8 7/8% Notes and 8 1/2% Notes were
     accelerated, the Company would not have sufficient funds available to repay
     the all of the 12 1/2% Notes, 11 1/4% Notes, 8 7/8% Notes and 8 1/2% Notes,
     unless it could arrange a refinancing of such notes.  The Company has used
     a portion of the net proceeds of the October 30 Offerings and December 23
     Offering to fund a pending acquisition of Shared Technologies.

               On December 17, 1997, the Company entered into a definitive
     agreement  for the acquisition of the Long Distance Savers group of
     companies ("LDS") for a purchase price of approximately $151.0 million, of
     which $120.0 million is payable in Intermedia common stock and $31.0
     million is payable in cash, in each case, subject to certain adjustments
     (the "LDS Acquisition").  Such acquisitions, if made, could divert the
     Company's resources and management time and would require integration with
     the Company's existing networks and services. There can be no assurance
     that the pending acquisitions of Shared Technologies and LDS will be
     consummated or that any other acquisitions will occur or that any such
     acquisitions, including the acquisitions of Shared Technologies and LDS, if
     made, would be on terms favorable to the Company or would be successfully
     integrated into the Company's operations.

               The Company is currently evaluating, has made offers with respect
     to, and is engaged in discussions regarding various other acquisition
     opportunities. These acquisitions could be funded by cash (including the
     proceeds of the October 30 Offerings and the December 23 Offering), a
     portion of the proceeds of the securities offered hereby (unless otherwise
     indicated in the applicable supplement prospectus) and/or the Company's
     securities. It is possible that one or more of such possible future
     acquisitions, if completed, could adversely affect the Company's funds from
     operations or cash available for distribution, in the short term or the
     long term or both, or increase the Company's debt, or such an acquisition
     could be followed by a decline in the market value of the Company's
     securities.

               Failure to Obtain Third Party Consents in connection with an
     Acquisition or Merger. The Company has consummated a number of acquistions
     over the past two years and expects to consummate additional acquisitions
     during the current fiscal year. In connection therewith, the Company may
     not have obtained, and in connection with future acquisitions may elect not
     to seek, all required consents from third parties with respect to acquired
     contracts. If an acquired contract required the consent of a third party
     and such consent was not obtained, the third party could assert a breach of
     the contract. The Company believes that the failure to obtain any such
     third party consents should not result in any material adverse consequences
     to the Company, although there can be no assurance that such a consequence
     will not result.
 
                   Class Action by DIGEX Stockholders. On June 5, 1997, the
     Company announced that it had agreed to acquire 100% of the outstanding
     equity of DIGEX (the "DIGEX Acquisition"). The acquisition was consummated
     through a tender offer for all of the outstanding shares of DIGEX, which
     closed on July 9, 1997, followed by a cash merger effective on July 11,
     1997 (the "Merger").

               On June 20, 1997, two purported class action complaints were
     filed in the Court of Chancery of the State of Delaware in and for New
     Castle County respectively by TAAM Associates, Inc. and David and Chaile
     Steinberg (the "Complaints"), purported stockholders of DIGEX, on behalf of
     all non-affiliated common stockholders of DIGEX, against Intermedia, DIGEX
     and the Directors of DIGEX (the "DIGEX Directors"). The Complaints allege
     that the DIGEX Directors violated their fiduciary duties to the public
     stockholders of DIGEX by agreeing to vote in favor of the Merger and that
     Intermedia knowingly aided and abetted such violation by offering to retain
     DIGEX management in their present positions and consenting to stock option
     grants to certain executive officers of DIGEX. The Complaints sought
     preliminary and permanent injunctions enjoining the Merger but no
     applications were made for such injunctions prior to the consummation of
     the Merger on July 11, 1997.  In addition, the Complaints seek cash damages
     from the DIGEX Directors.  In August 1997, a motion to dismiss the
     Complaints was filed on behalf of Intermedia, DIGEX and the DIGEX
     Directors.  The action has been dormant since that time.

               These cases are in their very early stages and no assurance can
     be given as to their ultimate outcome. Intermedia, after consultation with
     its counsel, believes that there are meritorious factual and legal defenses
     to the claims in the Complaints. Intermedia intends to defend vigorously
     the claims in the Complaints.

               Regulatory Approval of the October 30 Offerings and the December
     23 Offering.   Nine of the states in which the Company is certificated
     provide for prior approval or notification of the issuance of securities by
     the Company. Because of time constraints, the Company did not obtain such
     approval from any of the nine states prior to consummation of the October
     30 Offerings or the December 23 Offering. The requirements for these
     filings may have been pre-empted by the National Securities Market
     Improvement Act of 1996, although there is no case law on this point. The
     Company filed the necessary notifications and applications for approval in
     these states prior to the October 30 Offerings and has obtained approval or
     been advised that no formal approval is necessary in six states. The
     Company has also filed such notifications and applications with respect to
     the December 23 Offering. After consultation with counsel, the Company
     believes the remaining approvals will be granted and that obtaining such
     approvals subsequent to the October 30 Offerings and the December 23
     Offering should not result in any material adverse consequences to the
     Company, although there can be no assurance that such a consequence will
     not result.

               Significant Capital Requirements and Need for Additional
     Financing. Expansion of the Company's existing networks and services and
     the development of new networks and services require significant capital
     expenditures. Intermedia expects to fund its capital requirements through
     existing resources, joint ventures, debt or equity financing (including
     capital raised through the October 30 Offerings and the December 23
     Offering), credit availability and internally generated funds.  The Company
     expects that continued expansion of its business will require raising
     substantial equity and/or debt by the end of fiscal 1999.  Depending on
     market conditions, the Company may determine to raise additional capital
     before such time.  There can be no assurance, however, that Intermedia will
     be successful in raising sufficient debt or equity on terms that it will
     consider acceptable. Moreover, the Existing Indentures, the Series B
     Certificate of Designation, the Certificate of Designation setting forth
     the rights of the Series D Preferred Stock (the "Series D Certificate of
     Designation") and the Certificate of Designation setting forth the rights
     of the Series E Preferred Stock (the "Series E Certificate of Designation")
     impose certain restrictions upon the Company's ability to incur additional
     indebtedness or issue additional preferred stock. In addition, the
     Company's future capital requirements will depend upon a number of factors,
     including marketing expenses, staffing levels and customer growth, as well
     as other factors that are not within the Company's control, such as
     competitive conditions, government regulation and capital costs. Failure to
     generate sufficient funds may require Intermedia to delay or abandon some
     of its future expansion or expenditures, which would have a material
     adverse effect on its growth and its ability to compete in the
     telecommunications industry.

               Expansion Risk. The Company is experiencing a period of rapid
     expansion which management expects will increase in the near future. This
     growth has increased the operating complexity of the Company as well as the
     level of responsibility for both existing and new management personnel. The
     Company's ability to manage its expansion effectively will require it to
     continue to implement and improve its operational and financial systems and
     to expand, train and manage its employee base. The Company's inability to
     effectively manage its expansion could have a material adverse effect on
     its business.

               A portion of the Company's expansion may occur through
     acquisitions as an alternative to direct investments in the assets required
     to implement the expansion. No assurance can be given that suitable
     acquisitions can be identified, financed and completed on acceptable terms,
     or that the Company's future acquisitions, if any, will be successful or
     will not impair the Company's ability to service its outstanding
     obligations.

               Maintenance of Peering Relationships. The Internet is comprised
     of many Internet service providers ("ISPs") who operate their own networks
     and interconnect with other ISPs at various peering points. The
     establishment and maintenance of peering relationships with other ISPs is
     necessary in order to exchange traffic with other ISPs without having to
     pay settlement charges. Although the Company meets the industry's current
     standards for peering, there is no assurance that other national ISPs will
     maintain peering relationships with the Company. In addition, there may
     develop increasing requirements associated with maintaining peering with
     the major national ISPs with which the Company may have to comply. There
     can be no assurance that the Company

                                       8
<PAGE>
 
     will be able to expand or adapt their network infrastructure to meet the
     industry's evolving standards on a timely basis, at a commercially
     reasonable cost, or at all.

               Potential Liability of On-Line Service Providers. The law in the
     United States relating to the liability of on-line service providers and
     ISPs for information carried on, disseminated through or hosted on their
     systems is currently unsettled. Several private lawsuits seeking to impose
     such liability are currently pending. In one case brought against an ISP,
     Religious Technology Center v. Netcom On-Line Communication Services, Inc.,
     the United States District Court for the Northern District of California
     ruled in a preliminary phase that under certain circumstances ISPs could be
     held liable for copyright infringement. The Telecommunications Act of 1996
     (the "1996 Act") prohibits and imposes criminal penalties for using an
     interactive computer service to transmit certain types of information and
     content, such as indecent or obscene communications. On June 26, 1997, the
     Supreme Court affirmed the decision of a panel of three federal judges
     which granted a preliminary injunction barring enforcement of this portion
     of the 1996 Act to the extent that enforcement is based upon allegations
     other than obscenity or child pornography as an impermissible restriction
     on the First Amendment's right of free speech. In addition, numerous states
     have adopted or are currently considering similar types of legislation. The
     imposition upon ISPs or Web hosting sites of potential liability for
     materials carried on or disseminated through their systems could require
     the Company to implement measures to reduce their exposure to such
     liability, which may require the expenditure of substantial resources or
     the discontinuation of certain product or service offerings. The Company
     believes that it is currently unsettled whether the 1996 Act prohibits and
     imposes liability for any services provided by the Company should the
     content or information transmitted be subject to the statute. The increased
     attention focused upon liability issues as a result of these lawsuits,
     legislation and legislative proposals could affect the growth of Internet
     use. Any such liability or asserted liability could have a material adverse
     effect on the Company's business, financial condition and results of
     operations.

               Dependence upon Network Infrastructure; Risk of System Failure,
     Security Risks.  The Company's success in marketing its services to
     business and government users requires that the Company provide superior
     reliability, capacity and security via its network infrastructure. The
     Company's networks are subject to physical damage, power loss, capacity
     limitations, software defects, breaches of security (by computer virus,
     break-ins or otherwise) and other factors, certain of which have caused,
     and will continue to cause, interruptions in service or reduced capacity
     for the Company's customers. Similarly, the Company's ISP business relies
     on the availability of its network infrastructure for the provision of
     Internet connectivity. Interruptions in service, capacity limitations or
     security breaches could have a material adverse effect on the Company's
     business, financial condition and results of operations.

               Risks of Implementation; Need to Obtain Permits and Rights of
     Way. The Company is continuing to expand its existing networks. The Company
     has identified other expansion opportunities in the eastern half of the
     United States and is currently extending the reach of its networks to
     pursue such opportunities. There can be no assurance that the Company will
     be able to expand its existing networks or construct or acquire new
     networks as currently planned on a timely basis. The expansion of the
     Company's existing networks and its construction or acquisition of new
     networks will be dependent, among other things, on its ability to acquire
     rights-of-way and any required permits on satisfactory terms and conditions
     and on its ability to finance such expansion, acquisition and construction.
     In addition, the Company may require pole attachment agreements with
     utilities and incumbent local exchange carriers ("ILECs") to operate
     existing and future networks, and there can be no assurance that such
     agreements will be obtained or obtainable on reasonable terms. These
     factors and others could adversely affect the expansion of the Company's
     customer base on its existing networks and commencement of operations on
     new networks. If the Company is not able to expand, acquire or construct
     its networks in accordance with its plans, the growth of its business would
     be materially adversely affected.

               Competition. In each of its markets, the Company faces
     significant competition for the local network services, including local
     exchange services, it offers from incumbent local exchange carriers
     ("ILECs"), which currently dominate their local telecommunications markets.
     ILECs have long-standing relationships with their

                                       9
<PAGE>
 
     customers which relationships may create competitive barriers. Furthermore,
     ILECs may have the potential to subsidize competitive service from monopoly
     service revenues. In addition, a continuing trend toward business
     combinations and alliances in the telecommunications industry may create
     significant new competitors to the Company. The Company also faces
     competition in most markets in which it operates from one or more
     integrated communications services providers ("ICPs") and ILECs operating
     fiber optic networks. In addition, the Company faces competition in its
     integration services business from equipment manufacturers, the regional
     Bell operating companies ("RBOCs") and other ILECs, long distance carriers
     and systems integrators, and in its enhanced data services business
     (including Internet) from local telephone companies, long distance
     carriers, very small aperture terminal ("VSAT") providers, other ISPs and
     others. In particular, the market for Internet services is extremely
     competitive and there are limited barriers to entry. Many of the Company's
     existing and potential competitors have financial, personnel and other
     resources significantly greater than those of the Company.

               The Company believes that various legislative initiatives,
     including the recently enacted 1996 Act, have removed remaining legislative
     barriers to local exchange competition. Nevertheless, in light of the
     passage of the 1996 Act, regulators are also likely to provide ILECs with
     increased pricing flexibility as competition increases. If ILECs are
     permitted to lower their rates substantially or engage in excessive volume
     or term discount pricing practices for their customers, the net income or
     cash flow of ICPs and competitive local exchange carriers ("CLECs"),
     including the Company, could be materially adversely affected. In addition,
     while the Company currently competes with AT&T, MCI and others in the
     interexchange services market, the recent federal legislation permits the
     RBOCs to provide interexchange services once certain criteria are met. Once
     the RBOCs begin to provide such services, they will be in a position to
     offer single source service similar to that being offered by Intermedia.
     Recently, a Federal District Court in Texas found unconstitutional certain
     provisions of the 1996 Act restricting the RBOCs from offering long
     distance service in their operating regions until they could demonstrate
     that their networks have been made available to competitive providers of
     local exchange services in those regions.  If that decision is permitted to
     stand, it could result in RBOCs providing interexchange service in their
     operating regions sooner than previously expected.  In addition, AT&T and
     MCI have entered and other interexchange carriers have announced their
     intent to enter into the local exchange services market, which is
     facilitated by the 1996 Act's resale and unbundled network element
     provisions. The Company cannot predict the number of competitors that will
     emerge as a result of existing or new federal and state regulatory or
     legislative actions. Competition from the RBOCs with respect to
     interexchange services or from AT&T, MCI or others with respect to local
     exchange services could have a material adverse effect on the Company's
     business.

               Regulation. The Company is subject to varying degrees of federal,
     state and local regulation. The Company is not currently subject to price
     cap or rate of return regulation at the state or federal level, nor is it
     currently required to obtain FCC authorization for the installation,
     acquisition or operation of its interstate network facilities. Further, the
     FCC issued an order holding that non-dominant carriers, such as the
     Company, are required to withdraw interstate tariffs for domestic long
     distance service. That order has been stayed by a federal appeals court and
     it is not clear at this time whether the detariffing order will be
     implemented. Until further action is taken by the court, the Company will
     continue to maintain tariffs for these services. In June 1997, the FCC
     issued another order stating that non-dominant carriers, such as the
     Company, could withdraw their tariffs for interstate access services. While
     the Company has no immediate plans to withdraw its tariff, this FCC order
     allows the Company to do so. The FCC does require the Company to file
     tariffs on an ongoing basis for international traffic.

               On May 16, 1997, the FCC released an order that fundamentally 
     restructured the "access charges" that ILECs charge to interexchange
     carriers and end user customers. The Company believes that the FCC's new
     access charge rules do not adversely affect the Company's business plan,
     and that they in fact present significant new opportunities for new
     entrants, including the Company. Aspects of the access charge order may be
     changed in the future. Numerous parties have either filed appeals with
     federal courts or asked the FCC to reconsider portions of its new rules.

               The Company is generally subject to certification or 
     registration and tariff or price list filing requirements for intrastate
     services by state regulators. The 1996 Act and the issuance by the FCC of
     rules governing local competition, particularly those requiring the
     interconnection of all networks and the exchange of traffic among the ILEC
     and CLECs, as well as pro-competitive policies already developed by state
     regulatory commissions, have caused fundamental changes in the structure of
     the local exchange markets. On July 18, 1997, the U.S. Court of Appeals for
     the Eighth Circuit issued a decision vacating the FCC's pricing and
     "most favored nation" rules, as well as certain other of the FCC's
     interconnection rules. On October 14, 1997, the Eighth Circuit Court issued
     an order clarifying its previous decision. In this order, the Court held
     that ILECs have an obligation under the 1996 Act to offer other carriers
     access to the ILECs network elements on an unbundled basis, but the ILECs
     do not have an obligation to recombine those elements for use by other
     carriers. The FCC and other parties have requested the Supreme Court to
     review these decisions. Most recently, on January 22, 1998, the Eighth
     Circuit Court reiterated that the FCC is bound by the pricing policies of
     the state regulatory commissions regarding interconnection, unbundled
     access, resale, and transport and termination of local telecommunications
     traffic and rebuffed what it perceived as an attempt by the FCC to
     condition the RBOCs' provision of in-region long distance service on
     compliance with federal pricing policies regarding these items. Even though
     these decisions restrict the role of the FCC in the pricing and other
     issues, they remain subject to scrutiny and oversight by state regulatory
     commissions.

               Although the Company is not able to predict the impact of these
     decisions on future efforts to negotiate interconnection agreements with
     ILECs, the Company's analysis shows that interconnection arrangements that
     have been approved or mandated by state regulatory commissions have been
     consistent with the intent of the 1996 Act to expand local competition and
     the Company's business plan. These regulatory developments create
     opportunities for new entrants offering local exchange services to capture
     a portion of the ILECs' nearly 100% market share. Due to the rapid
     development and continuing growth of the Company's sales force and its
     competitive advantages in providing integrated telecommunications services,
     the Company believes that it is well positioned to capitalize on the new
     market opportunities emerging in the local exchange market.

               Although passage of the 1996 Act should result in increased 
     opportunities for companies that are competing with the ILECs, no assurance
     can be given that changes in current or future regulations adopted by the
     FCC or state regulators or other legislative or judicial initiatives
     relating to the telecommunications industry would not have a material
     adverse effect on the Company. In addition, although the 1996 Act provides
     incentives to the ILECs that are subsidiaries of RBOCs to enter the long
     distance service market by requiring ILECs to negotiate interconnection
     agreements with local competitors, there can be no assurance that these
     ILECs will negotiate quickly with competitors such as the Company for the
     required interconnection of the competitor's networks with those of the
     ILECs or that such agreements will be favorable. Moreover, on December 31,
     1997, a Federal District Court in Texas found unconstitutional certain
     provisions of the 1996 Act restricting the RBOCs from offering long
     distance service in their operating regions until they could demonstrate
     that their networks have been made available to competitive providers of
     local exchange services in those regions. The United States and some long
     distance companies have requested a stay of this decision and it is
     expected that they, and others, will seek its reversal on appeal. If the
     District Court's decision is permitted to stand, it could result in the
     RBOCs providing interexchange service in their operating regions sooner
     than previously expected.

               Potential Diminishing Rate of Growth. During the period from 1994
     to 1996, the Company's revenues have grown at a compound annual growth rate
     of 169%. While the Company expects to continue to grow, as its size
     increases it is likely that its rate of growth will diminish.

               Risk of New Service Acceptance by Customers. The Company has
     recently introduced a number of services, primarily local exchange
     services, that the Company believes are important to its long-term growth.
     The success of these services will be dependent upon, among other things,
     the willingness of customers to accept the Company as the provider of such
     services. No assurance can be given that such acceptance will occur; the
     lack of such acceptance could have a material adverse effect on the
     Company.

               Rapid Technological Changes. The telecommunications industry is
     subject to rapid and significant changes in technology. While Intermedia
     believes that, for the foreseeable future, these changes will neither
     materially affect the continued use of its fiber optic networks nor
     materially hinder its ability to acquire necessary technologies, the effect
     on the business of Intermedia of technological changes such as changes
     relating to emerging wireline and wireless transmission technologies,
     including software protocols, cannot be predicted.

               Dependence on Key Personnel. The Company's business is managed by
     a small number of key management and operating personnel, the loss of
     certain of whom could have a material adverse impact on the Company's
     business. The Company believes that its future success will depend in large
     part on its continued ability to attract and retain highly skilled and
     qualified personnel. None of the Company's key executives, other than David
     C. Ruberg, President, Chief Executive Officer and Chairman of the Board, is
     a party to a long-term employment agreement with the Company.

               Risk of Cancellation or Non-Renewal of Network Agreements,
     Licenses and Permits. The Company has lease and/or purchase agreements for
     rights-of-way, utility pole attachments, conduit and dark fiber for its
     fiber optic networks. Although the Company does not believe that any of
     these agreements will be cancelled in the near future, cancellation or non-
     renewal of certain of such agreements could materially adversely affect the
     Company's business in the affected metropolitan area. In addition, the
     Company has certain licenses and permits from local government authorities.
     The 1996 Act requires that local government authorities treat
     telecommunications carriers in a competitively neutral, non-discriminatory
     manner, and that most utilities, including most ILECs and electric
     companies, afford alternative carriers access to their poles, conduits and
     rights-of-way at reasonable rates on non-discriminatory terms and
     conditions. There can be no assurance that the Company will be able to
     maintain its existing franchises, permits and rights or to obtain and
     maintain the other franchises, permits and rights needed to implement its
     strategy on acceptable terms.

               Dependence on Business from Interexchange Carriers ("IXCs"). For
     the year ended December 31, 1996, approximately 10% of the Company's
     consolidated revenues were attributable to access services provided to
     IXCs. The loss of access revenues from IXCs in general could have a
     material adverse effect on the Company's business.

               In addition, the Company's growth strategy assumes increased
     revenues from IXCs from the deployment of local/long distance voice
     switches on its networks and the provision of switched access origination
     and termination services. There is no assurance that the IXCs will continue
     to increase their utilization of the Company's services, or will not reduce
     or cease their utilization of the Company's services, which could have a
     material adverse effect on the Company.

               Business Combinations; Change of Control. The Company has from
     time to time held, and continues to hold, preliminary discussions with (i)
     potential strategic investors who have expressed an interest in making an
     investment in or acquiring the Company and (ii) potential joint venture
     partners looking toward the formation of strategic alliances that would
     expand the reach of the Company's networks or services without necessarily
     requiring an additional investment in the Company. In addition to providing
     additional growth capital, management believes that an alliance with an
     appropriate strategic investor would provide operating synergy to, and
     enhance the competitive positions of, both Intermedia and the investor
     within the rapidly consolidating telecommunications industry. There can be
     no assurance that agreements for any of the foregoing will be reached. An
     investment, business combination or strategic alliance could constitute a
     change of control. The Existing Indentures provide that a change of control
     would require the Company to repay the indebtedness outstanding under such
     instruments. If a change of control does occur, there is no assurance that
     the Company would have sufficient funds to make such repayments or could
     obtain any additional debt or equity financing that could be necessary in
     order to repay the Existing Senior Notes.

               Anti-Takeover Provisions. The Company's Certificate of
     Incorporation and Bylaws, the provisions of the Delaware General
     Corporation Law (the "DCGL"), the Existing Indentures, the Series B
     Certificate of Designation,  the Series D Certificate of Designation and
     the Series E Certificate of Designation may make it difficult in some
     respects to effect a change in control of the Company and replace incumbent
     management. In addition, the Company's Board of Directors has adopted a
     Stockholder's Rights Plan, pursuant to which rights to acquire a series of
     preferred stock, exercisable upon the occurrence of certain events, were
     distributed to its stockholders. The existence of these provisions may have
     a negative impact on the price of the Common Stock, may discourage third
     party bidders from making a bid for the Company, or may reduce any premiums
     paid to stockholders for their Common Stock. In addition, the Board has the
     authority to fix the rights and preferences of, and to issue shares of, the
     Company's preferred stock, which may have the effect of delaying or
     preventing a change in control of the Company without action by its
     stockholders.

               Shares Eligible for Future Sale. Future sales of shares by
     existing stockholders under Rule 144 of the Securities Act, or through the
     exercise of outstanding registration rights or the issuance of shares of
     Common Stock upon the exercise of options or warrants or conversion of
     convertible securities could materially adversely affect the market price
     of shares of Common Stock and could materially impair the Company's future
     ability to raise capital through an offering of equity securities.
     Substantially all of the Company's outstanding shares, other than those
     held by affiliates, are transferable without restriction under the
     Securities Act.  No predictions can be made as to the effect, if any, that
     market sales of such shares or the availability of such shares for future
     sale will have on the market price of shares of Common Stock prevailing
     from time to time.

               Forward Looking Statements. The statements contained in this
     Prospectus that are not historical facts are "forward-looking statements"
     (as such term is defined in the Private Securities Litigation Reform Act of
     1995), which can be identified by the use of forward-looking terminology
     such as "estimates," "projects," "anticipates," "expects," "intends,"
     "believes," or the negative thereof or other variations thereon or
     comparable terminology, or by discussions of strategy that involve risks
     and uncertainties. Management wishes to caution the reader that these
     forward-looking statements are only estimates or predictions. No assurance
     can be given that future results will be achieved; actual events or results
     may differ materially as a result of risks facing the Company or actual
     results differing from the assumptions underlying such statements.


     RATIO OF EARNINGS TO COMBINED FIXED CHARGES AND PREFERRED STOCK DIVIDENDS
  
               The Company's historical earnings have been insufficient to cover
     combined fixed charges and dividends on preferred stock by $0.6 million,
     $2.3 million, $3.3 million, $19.8 million and $60.0 million for each of the
     years ended December 31, 1992, 1993, 1994, 1995 and 1996, respectively. In
     addition, insufficiencies of $37.6 million and $187.0 million were
     experienced in the nine-month periods ended September 30, 1996 and 1997,

                                       12

     respectively. On a pro forma basis, after giving effect to the DIGEX, EMI,
     NetSolve and UTT acquisitions, the pending acquisition of Shared
     Technologies and the March 1997 offerings, July 9 Offerings, October 30
     Offerings and December 23 Offering, the Company's earnings were
     insufficient to cover combined fixed charges and dividends on preferred
     stock by $274.0 million for the year ended December 31, 1996 and by $321.1
     million for the nine months ended September 30, 1997.

               See "Risk Factors Substantial Indebtedness; Insufficiency of
     Earnings to Cover Fixed Charges" for a further discussion of factors which
     may have an impact on the Company's ratio of earnings to combined fixed
     charges and preferred stock dividends.

                                  THE COMPANY

               Intermedia is a rapidly growing ICP, offering a full suite of
     local, long distance and enhanced data telecommunications services to
     business and government end user customers, long distance carriers, ISPs,
     resellers and wireless communications companies. Founded in 1987, the
     Company is currently the third largest (based on annualized
     telecommunications services revenues) among providers generally referred to
     as CLECs after MFS Communications Company, Inc. and Teleport Communications
     Group Inc. As of September 30, 1997, the Company had sales offices in 43
     cities throughout the eastern half of the United States and offered a full
     product package of telecommunications services in 19 metropolitan
     statistical areas. In April 1996, Intermedia became one of the first ICPs
     in the United States to provide integrated switched local and long distance
     service and as of December 16, 1997 had thirteen switches in service.  The
     Company provides enhanced data services, including frame relay, a
     synchronous transfer mode ("ATM") and Internet access services, primarily
     to business and government customers (including over 100 ISPs), in
     approximately 3,800 cities nationwide, utilizing approximately 130 Company-
     owned data switches. Intermedia also serves as a facilities-based
     interexchange carrier to approximately 15,000 customers nationwide.
     Intermedia continues to increase its customer base and network density in
     the eastern half of the United States and is pursuing attractive
     opportunities to add additional services and expand into complementary
     geographic markets.

               Intermedia was incorporated in the State of Delaware on November
     9, 1987, as the successor to a Florida corporation that was founded in
     1986. The Company's principal offices are located at 3625 Queen Palm Drive,
     Tampa, Florida 33619, and its telephone number is (813) 829-0011.



                                USE OF PROCEEDS

               Unless otherwise specified in the Prospectus Supplement, the net
     proceeds from the sale of the Securities will be used by the Company to
     finance the continued expansion of Intermedia'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.

               Unless otherwise specified in the Prospectus Supplement, 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
     businesses that the Company may acquire will likely consist of companies
     that own existing networks or companies that provide services that
     complement the Company's existing businesses. The Existing Indentures
     prohibit the Company from acquiring assets or businesses which are not
     involved in the Telecommunications Business (as defined therein). The
     Company is currently evaluating various acquisition opportunities, however,
     no assurance can be given that any potential acquisition will be
     consummated.

               Prior to the application of the net proceeds as described above,
     such funds will be invested in short-term investment grade securities.

                         DESCRIPTION OF DEBT SECURITIES


               The following description of the terms of the Debt Securities
     sets forth certain general terms and provisions of the Debt Securities to
     which any Prospectus Supplement may relate. The particular terms of the
     Debt Securities being offered (the "Offered Debt Securities"), the extent,
     if any, to which such general provisions may apply to the Securities and
     any modifications of or additions to the general terms of the Debt
     Securities applicable in the case of the Offered Debt Securities will be
     described in the Prospectus Supplement relating to such Debt Securities.

               The Senior Debt Securities are to be issued under an indenture to
     be dated as of a date on or prior to the first issuance of Senior Debt
     Securities, as supplemented from time to time (the "Senior Indenture"),
     between the Company and a trustee to be determined by the Company (the
     "Senior Debt Trustee"), and the Subordinated Debt Securities are to be
     issued under an indenture to be dated as of a date on or prior to the first
     issuance of Subordinated Debt Securities, as supplemented from time to time
     (the "Subordinated Indenture"), between the Company and a trustee to be
     determined by the Company (the "Subordinated Debt Trustee"). The term
     "Trustee" as used herein shall refer to either the Senior Debt Trustee or
     the Subordinated Debt Trustee, as appropriate, for Senior Debt Securities
     or Subordinated Debt Securities. The form of the Senior Indenture and the
     form of the Subordinated Indenture (being referred to herein collectively
     as the "Indentures" and individually as an "Indenture") are filed as
     exhibits to the Registration Statement. The Indentures are subject to and
     governed by the Trust Indenture Act of 1939, as amended (the "TIA"). The
     statements made under this heading relating to the Debt Securities and the
     Indentures are summaries of the provisions thereof, do not purport to be
     complete and are qualified in their entirety by reference to the
     Indentures, including the definitions of certain terms therein and in the
     TIA. Certain capitalized terms used below but not defined herein have the
     meanings ascribed to them in the applicable Indenture.

     GENERAL

               The Debt Securities will be direct, and may be secured or
     unsecured, obligations of the Company.  The indebtedness represented by the
     unsecured Senior Debt Securities will rank equally with all other unsecured
     and unsubordinated indebtedness of the Company. The indebtedness
     represented by the secured Senior Debt Securities will rank equally with
     all other secured and unsubordinated indebtedness of the Company and will
     rank senior to all other unsecured indebtedness of the Company with respect
     to the security interest.  The indebtedness represented by the Subordinated
     Debt Securities will be subordinated in right of payment to the prior
     payment in full of the Senior Indebtedness of the Company (including the
     Senior Debt Securities) as described under "Subordination" below. The
     Indentures provide that the Debt Securities may be issued without limit as
     to aggregate principal amount, in one or more series, in each case as
     established from time to time in or pursuant to authority granted by a
     resolution of the Board of Directors of the Company or as established in
     one or more indentures supplemental to the Indenture. All Debt Securities
     of one series need not be issued at the same time and, unless otherwise
     provided, a series may be reopened, without the consent of the holders of
     the Debt Securities of such series, for issuances of additional Debt
     Securities of such series.

               The Indentures provide that there may be more than one Trustee
     thereunder, each with respect to one or more series of Debt Securities. Any
     Trustee under the Indentures may resign or be removed with respect to one
     or more series of Debt Securities, and a successor Trustee may be appointed
     to act with respect to such series. In the event that two or more persons
     are acting as Trustee with respect to different series of Debt Securities,
     each such Trustee shall be a Trustee of a trust under the Indenture
     separate and apart from the trust administered by any other Trustee, and,
     except as otherwise indicated herein, any action described herein to be
     taken by the Trustee may be taken by each such Trustee with respect to, and
     only with respect to, the one or more series of Debt Securities for which
     it is Trustee under the applicable Indenture.

          Senior Debt Securities or Subordinated Debt Securities (which shall
          distinguish the Debt Securities of such Offered Debt Securities from
          all other series of Debt Securities).

               (2) The aggregate principal amount of the Offered Debt Securities
          and any limit on the aggregate principal amount of the Offered Debt
          Securities of such series.

          Debt Securities will be issued and, if other than the principal amount
          thereof, the portion of the principal amount thereof payable upon
          declaration of acceleration of the maturity or upon redemption thereof
          or the method by which such portion shall be determined.

               (4) The date or dates on which or periods during which the
          Offered Debt Securities may be issued, and the date or dates, or the
          method by which such date or dates will be determined, on which the
          principal of (and premium, if any, on) the Offered Debt Securities
          are, or may be, payable (which may be determined by the Company from
          time to time as set forth in the Prospectus Supplement for such
          Offered Debt Securities).

               (5) The rate or rates (which may be variable or fixed) at which
          the Offered Debt Securities will bear interest, if any, or the method
          by which such rate or rates shall be determined, the date or dates
          from which such interest, if any, shall accrue or the method by which
          such date or dates shall be determined, the interest payment dates on
          which such interest will be payable (or the method of determination
          thereof) and the record dates, if any, for the interest payable on
          such interest payment dates, and the notice, if any, to holders
          regarding the determination of interest and the manner of giving such
          notice, the basis upon which interest shall be calculated if other
          than that of a 360-day year of twelve 30-day months and any conditions
          or contingencies as to the payment of interest in cash or
          otherwise, if any.

          any) and interest on the Offered Debt Securities shall be payable; the
          extent to which, or the manner in which, any interest payable on any
          Global Note (as defined below) on an interest payment date will be
          paid, and the manner in which any principal of, or premium, if any,
          on, any Global Note will be paid and whether any Global Note will
          require any notation to evidence payment of principal or interest.

               (7) The obligation, if any, of the Company to redeem, repay,
          purchase or offer to purchase the Offered Debt Securities pursuant to
          any mandatory redemption, sinking fund or analogous provisions or upon
          other conditions or at the option of the Holder thereof and the period
          or periods within which, or the dates on which, the prices at which
          and the terms and conditions upon which the Offered Debt Securities
          shall be redeemed, repaid, purchased or offered to be purchased, in
          whole or in part, pursuant to such obligation.

               (8) The right, if any, of the Company to redeem the Offered Debt
          Securities at its option and the period or periods within which, or

          terms and conditions upon which Offered Debt Securities may be
          redeemed, if any, in whole or in part, at the option of the Company or
          otherwise.

               (9) The denominations of the Offered Debt Securities if other
          than denominations of $1,000 and any integral multiple thereof.

                                       16
<PAGE>
 
               (10) Whether the Offered Debt Securities are to be issued as
          original issue discount securities ("Discount Securities") and the
          amount of discount at which such Offered Debt Securities may be issued
          and, if other than the principal amount thereof, the portion of the
          principal amount of Offered Debt Securities which shall be payable
          upon declaration of acceleration of the Maturity thereof upon an Event
          of Default.

               (11) Provisions, if any, for the defeasance or discharge of
          certain of the Company's obligations with respect to the Offered Debt

               In the event that Discount Securities are issued, the Federal
     income tax consequences and other special considerations applicable to such
     Discount Securities will be described in the Prospectus Supplement relating
     thereto.

               The general provisions of the Indentures do not contain any
     provisions that would limit the ability of the Company or its Subsidiaries
     to incur indebtedness or that would afford holders of Debt Securities
     protection in the event of a highly leveraged or similar transaction
     involving the Company or its Subsidiaries. Reference is made to the
     accompanying Prospectus Supplement for information with respect to any
     deletions from, modifications of or additions, if any, to the Events of

     Debt Securities or any covenants or other provisions providing event risk

               All of the Debt Securities of a series need not be issued at the
     same time, and may vary as to interest rate, maturity and other provisions
     and unless otherwise provided, a series may be reopened for issuance of
     additional Debt Securities of such series.

               The Debt Securities of certain series may be issued under the
     Indentures upon the exchange or conversion of exchangeable or convertible
     Debt Securities. The specific terms of exchange or conversion of any such
     Debt Securities and the specific terms of the Debt Securities issuable upon
     any such exchange or conversion will be described in the Prospectus
     Supplement relating to any such exchangeable or convertible Debt
     Securities.


     DENOMINATIONS, REGISTRATION AND TRANSFER

               Unless specified in the Prospectus Supplement, the Debt
     Securities of any series shall be issuable in denominations of $1,000 and
     any integral multiple thereof and shall be payable only in U.S. dollars.
     The Indentures also provide that Debt Securities of a series may be
     issuable in global form. See "Book-Entry Debt Securities."

               Upon surrender for registration of transfer of any Registered
     Security of any series at the office or agency of the Company maintained
     for such purpose, the Company shall deliver, in the name of the designated
     transferee, one or more new Registered Securities of the same series of
     like aggregate principal amount of such denominations as are authorized for
     Registered Securities of such series and of a like Stated Maturity and with
     like terms and conditions. No service charge will be made for any transfer
     or exchange of Debt Securities, but the Company may require payment of a
     sum sufficient to cover any tax or other governmental charge payable in
     connection therewith.

               The Company shall not be required (i) to register, transfer or
     exchange Debt Securities of any series during a period beginning at the
     opening of business 15 days before the day of the transmission of a notice
     of redemption of Debt Securities of such series selected for redemption and
     ending at the close of business on the day of such transmission, or (ii) to
     register, transfer or exchange any Debt Security so selected for redemption
     in whole or in part, except the unredeemed portion of any Debt Security
     being redeemed in part.


     EVENTS OF DEFAULT

               Under the Indentures, "Event of Default" with respect to the Debt
     Securities of any series means any one of the following events (whatever
     the reason for such Event of Default and whether it shall be

                                       18
<PAGE>
 
     voluntary or involuntary or be effected by operation of law, pursuant to
     any judgment, decree or order of any court or any order, rule or regulation
     of any administrative or governmental body): (1) default in the payment of
     any interest upon any Debt Security of such series when it becomes due and
     payable, and continuance of such default for a period of 30 days; (2)
     default in the payment of the principal of (and premium, if any, on) any
     Debt Security of such series at its Maturity; (3) default in the deposit of
     any sinking fund payment, when and as due by the terms of a Debt Security
     of such series; (4) default in the performance, or breach, of any covenant
     or warranty in the applicable Indenture (other than a covenant or warranty
     a default in whose performance or whose breach is elsewhere specifically
     dealt with or which expressly has been included in the applicable Indenture
     solely for the benefit of Debt Securities of a series other than such
     series), and continuance of such default or breach for a period of 30 days
     after there has been given by registered or certified mail, to the Company
     by the applicable Trustee or to the Company and the applicable Trustee by
     the Holders of at least 30% in principal amount of the outstanding Debt
     Securities of such series, a written notice specifying such default or
     breach and requiring it to be remedied and stating that such notice is a
     "Notice of Default"; (5) certain events of bankruptcy, insolvency or
     reorganization with respect to the Company; or (6) any other Event of
     Default provided with respect to Debt Securities of that series.

               Each Indenture requires the Company to file with the applicable
     Trustee, annually, an officers' certificate as to the Company's compliance
     with all conditions and covenants under the applicable Indenture. Each
     Indenture provides that the applicable Trustee may withhold notice to the
     Holders of a series of Debt Securities of any default (except payment
     defaults on such Debt Securities) if it considers such withholding to be in
     the interest of the Holders of such series of Debt Securities.

               If an Event of Default with respect to Debt Securities of any
     series at the time outstanding occurs and is continuing, then in every case
     the applicable Trustee or the Holders of not less than 25% in principal
     amount of the outstanding Debt Securities of such series may declare the
     principal amount (or, if any Debt Securities of such series are Discount
     Securities, such portion of the principal amount of such Discount
     Securities as may be specified in the terms of such Discount Securities) of
     all the Debt Securities of such series to be due and payable immediately,
     by a notice in writing to the Company (and to the applicable Trustee if
     given by Holders), and upon any such declaration such principal amount (or
     specified amount), plus accrued and unpaid interest (and premium, if any)
     shall become immediately due and payable. Upon payment of such amount, all
     obligations of the Company in respect of the payment of principal of the
     Debt Securities of such series shall terminate.

               Subject to the provisions of each Indenture relating to the
     duties of the applicable Trustee, in case an Event of Default with respect
     to Debt Securities of a particular series shall occur and be continuing,
     the applicable Trustee shall be under no obligation to exercise any of its
     rights or powers under such Indenture at the request, order or direction of
     any of the Holders of Debt Securities of that series, unless such Holders
     shall have offered to the applicable Trustee reasonable security or
     indemnity against the costs, expenses and liabilities which might be
     incurred by it in complying with such request or direction. Subject to such
     provisions for the indemnification of the applicable Trustee, the Holders
     of a majority in principal amount of the outstanding Debt Securities of
     such series shall have the right to direct the time, method and place of
     conducting any proceeding for any remedy available to the applicable
     Trustee under such Indenture, or exercising any trust or power conferred on
     the applicable Trustee with respect to the Debt Securities of that series.

               At any time after such a declaration of acceleration with respect
     to Debt Securities of any series has been made and before a judgment or
     decree for payment of the money due has been obtained by the applicable
     Trustee as provided in the Indentures, the Holders of a majority in
     principal amount of the outstanding Debt Securities of such series, by
     written notice to the Company and the applicable Trustee, may rescind and
     annul such declaration and its consequences, subject to any terms or
     conditions specified in the applicable Prospectus Supplement.

     MERGER OR CONSOLIDATION

               Each Indenture provides that the Company may not consolidate with
     or merge with or into or wind up into (whether or not the Company is the
     surviving corporation) or sell, assign, convey, transfer or lease its
     properties and assets substantially as an entirety to any Person, unless
     (1) the corporation formed by such consolidation or into which the Company
     is merged or the Person which acquires by conveyance or transfer, or which
     leases, the properties and assets of the Company substantially as an
     entirety (the "successor corporation") is a corporation organized and
     existing under the laws of the United States or any State or territory
     thereof or the District of Columbia and expressly assumes by a supplemental
     indenture the due and punctual payment of the principal of (and premium, if
     any) and interest on all the Debt Securities issued under the applicable
     Indenture and the performance of every covenant in the applicable Indenture
     on the part of the Company to be performed or observed; (2) immediately
     after giving effect to such transaction, no Event of Default under the
     applicable Indenture, and no event which, after notice or lapse of time, or
     both, would become such an Event of Default, shall have happened and be
     continuing; and (3) such other conditions as may be specified in the
     applicable Prospectus Supplement.


     MODIFICATION OR WAIVER

               Without prior notice to or consent of any Holders, the Company
     and the applicable Trustee, at any time and from time to time, may modify
     the applicable Indenture for any of the following purposes: (1) to evidence
     the succession of another corporation to the rights of the Company and the
     assumption by such successor of the covenants and obligations of the
     Company in the applicable Indenture and in the Debt Securities issued
     thereunder in accordance with the terms of the applicable Indenture; (2) to
     add to the covenants of the Company for the benefit of the Holders of all
     or any series of Debt Securities (and if such covenants are to be for the
     benefit of less than all series, stating that such covenants are expressly
     being included solely for the benefit of such series), or to surrender any
     right or power conferred in the applicable Indenture upon the Company; (3)
     to add any additional Events of Default (and if such Events of Default are
     to be applicable to less than all series, stating that such Events of
     Default are expressly being included solely to be applicable to such
     series); (4) to change or eliminate any of the provisions of the applicable
     Indenture, provided that any such change or elimination will become
     effective only when there is no outstanding Debt Security issued thereunder
     of any series created prior to such modification which is entitled to the
     benefit of such provision and as to which such modification would apply;
     (5) to secure the Debt Securities issued thereunder or to provide that any
     of the Company's obligations under the Debt Securities or the applicable
     Indenture shall be guaranteed and the terms and conditions for the release
     or substitution of such security or guarantee; (6) to supplement any of the
     provisions of the applicable Indenture to such extent as is necessary to
     permit or facilitate the defeasance and discharge of any series of Debt
     Securities, provided that any such action will not adversely affect the
     interests of the Holders of Debt Securities of such series or any other
     series of Debt Securities issued under such Indenture in any material
     respect; (8) to establish the form or terms of Debt Securities as permitted
     by the applicable Indenture; (9) to evidence and provide for the acceptance
     of appointment thereunder by a successor Trustee with respect to one or
     more series of Debt Securities and to add to or change any of the
     provisions of the applicable Indenture as is necessary to provide for or
     facilitate the administration of the trusts thereunder by more than one
     Trustee; or (10) to cure any ambiguity, to correct or supplement any
     provision in the applicable Indenture which may be defective or
     inconsistent with any other provision therein, to eliminate any conflict
     between the terms of the applicable Indenture and the Debt Securities
     issued thereunder and the TIA or to make any other provisions with respect
     to matters or questions arising under the applicable Indenture which will
     not be inconsistent with any provision of the applicable Indenture;
     provided such other provisions shall not adversely affect the interests of
     the Holders of outstanding Debt Securities of any series created thereunder
     prior to such modification in any material respect.

               With the written consent of the Holders of not less than a
     majority in principal amount of the outstanding Debt Securities of each
     series affected by such modification voting separately, the Company and the

                                       20
<PAGE>
 
     applicable Trustee may modify the applicable Indenture for the purpose of
     adding any provisions to or changing in any manner or eliminating any of
     the provisions of the applicable Indenture or of modifying in any manner
     the rights of the Holders of Debt Securities under the applicable
     Indenture; provided, however, that such modifications may not, without the
     consent of the Holder of each outstanding Debt Security of each series
     affected, conflict with the required provisions of the TIA or make any
     change or modification specified as requiring the consent of each such
     Holder in the applicable Prospectus Supplement.

               A modification which changes or eliminates any covenant or other
     provision of the applicable Indenture with respect to one or more
     particular series of Debt Securities or which modifies the rights of the
     Holders of Debt Securities of such series with respect to such covenant or
     other provision, shall be deemed not to affect the rights under the
     applicable Indenture of the Holders of Debt Securities of any other series.

               Each of the Indentures provides that the Holders of not less than
     a majority in aggregate principal amount of the then outstanding Debt
     Securities of any series, by notice to the relevant Trustee, may on behalf
     of the Holders of the Debt Securities of such series waive any Default or
     Event of Default and its consequences under the applicable Indenture,
     except (1) a continuing Default or Event of Default in the payment of
     interest on, premium, if any, or the principal of, any such Debt Security
     held by a non-consenting Holder or (2) a default in respect of a covenant
     or provision hereof which cannot be modified or amended without the consent
     of the Holder of each outstanding Debt Security of each series affected.


     SUBORDINATION

               Upon any distribution of assets of the Company upon the
     dissolution, winding up, liquidation or reorganization of the Company, the
     payment of the principal of (and premium, if any) and interest on the
     Subordinated Debt Securities will be subordinated to the extent provided in
     the Subordinated Indenture or as described in the applicable Prospectus
     Supplement in right of payment to the prior payment in full of all Senior
     Indebtedness, including Senior Debt Securities, but the obligation of the
     Company to make payment of principal (and premium, if any) or interest on
     the Subordinated Debt Securities will not otherwise be affected. Unless
     otherwise indicated in a Prospectus Supplement, no payment on account of
     principal (and premium, if any), sinking funds or interest may be made on
     the Subordinated Debt Securities at any time when there is a default in the
     payment of principal (and premium, if any), interest or certain other
     obligations on Senior Indebtedness. In addition, the Prospectus Supplement
     for each series of Subordinated Debt Securities may provide that payments
     on account of principal (any premium, if any) or interest in respect of
     such Subordinated Debt Securities may be delayed or not paid under the
     circumstances and for the periods specified in such Prospectus Supplement.
     Unless otherwise indicated in a Prospectus Supplement, in the event that,
     notwithstanding the foregoing, any payment by the Company described in the
     foregoing sentence is received by the Trustee under the Subordinated
     Indenture or the Holders of any of the Subordinated Debt Securities before
     all Senior Indebtedness is paid in full, such payment or distribution shall
     be paid over to the Holders of such Senior Indebtedness or on their behalf
     for application to the payment of all such Senior Indebtedness remaining
     unpaid until all such Senior Indebtedness shall have been paid in full,
     after giving effect to any concurrent payment or distribution to the
     Holders of such Senior Indebtedness. Subject to payment in full of Senior
     Indebtedness, the Holders of the Subordinated Debt Securities will be
     subrogated to the rights of the Holders of the Senior Indebtedness to the
     extent of payments made to the Holders of such Senior Indebtedness out of
     the distributive share of the Subordinated Debt Securities.

               By reason of such subordination, in the event of a distribution
     of assets upon insolvency, certain general creditors of the Company may
     recover more, ratably, than holders of the Subordinated Debt Securities.
     The Subordinated Indenture provides that the subordination provisions
     thereof shall not apply to money and securities held in trust pursuant to
     the satisfaction and discharge and the legal defeasance provisions of the
     Subordinated Indenture.

     offering of a series of Subordinated Debt Securities, the accompanying
     Prospectus Supplement or the information incorporated by reference therein
     will set forth the approximate amount of Senior Indebtedness outstanding as
     of a recent date. "Senior Indebtedness" with respect to any series of
     Subordinated Debt Securities shall have the meaning specified in the
     applicable Prospectus Supplement for such series.

                    DESCRIPTION OF OUTSTANDING INDEBTEDNESS


     12 1/2% NOTES

       The Company has outstanding an aggregate principal amount of $330,000,000
     of 12 1/2% Senior Discount Notes due 2006 (the "12 1/2% Notes), with an
     aggregate accreted value of $213,001,000 as of September 30, 1997. The 12
     1/2% Notes were issued at a substantial discount from their principal
     amount and mature on May 15, 2006.Cash interest does not accrue on the
     12 1/2% Notes prior to May 15, 2001. Commencing November 15, 2001, cash
     interest on the 12 1/2% Notes will be payable semi-annually in arrears on
     May 15 and November 15 of each year at a rate of 12 1/2% per annum. The 12
     1/2% Notes may be redeemed at the Company's option at any time, in whole or
     in part, on or after May 15, 2001 upon payment of the redemption price plus
     accrued and unpaid interest, if any, to the date of redemption. The 12 1/2%
     Notes are unsecured obligations of the Company ranking pari passu in right
     of payment of principal and interest with all other existing and future
     senior indebtedness of the Company, including the 11 1/4% Notes, the 8 7/8%
     Notes and the 8 1/2 Notes, and rank senior to any future subordinated
     indebtedness. In the event of a change of control of the Company prior to
     May 15, 2001, holders of the 12 1/2% Notes have the right to require the
     Company to repurchase their 12 1/2% Notes, in whole or in part, at a price
     equal to 101% of the accreted value thereof or, in the case of any such
     purchase on or after May 15, 2001, at 101% of the principal amount thereof,
     plus accrued and unpaid interest, if any, to the date of purchase.
 
       The covenants in the 12 1/2% Notes Indenture are substantially similar to
     the covenants in the indentures for the 11 1/4% Notes and the 8 7/8% Notes
     and are substantially similar (with modifications to certain definitions
     and exceptions) to the covenants in the 8 1/2% Notes Indenture.  The 12
     1/2% Notes Indenture contains certain covenants that, among other things,
     limit the ability of the Company and its subsidiaries to make certain
     restricted payments, incur additional indebtedness and issue preferred
     stock, pay dividends or make other distributions, repurchase equity
     interests or subordinated indebtedness, engage in sale and leaseback
     transactions, create certain liens, enter into certain transactions with
     affiliates, sell assets of the Company or its subsidiaries, conduct certain
     lines of business, issue or sell equity interests of the Company's
     subsidiaries or enter into certain mergers and consolidations. In addition,
     under certain circumstances, the Company is required to offer to purchase
     12 1/2% Notes at a price equal to 100% of the accreted value thereof, if
     such circumstances occur prior to May 15, 2001, or at 100% of the principal
     amount thereof, if such circumstances occur on or after May 15, 2001, plus
     accrued and unpaid interest, if any, to the date of purchase with the
     proceeds of certain asset sales. This description of the 12 1/2% Notes is
     intended as a summary and is qualified in its entirety by reference to the
     12 1/2% Notes Indenture.

     11 1/4% NOTES

          The Company has outstanding an aggregate principal amount at maturity
     of $649,000,000 of 11 1/4% Senior Discount Notes due 2007 (the "11 1/4%
     Notes), with an aggregate accreted value of $383,666,000 as of September
     30, 1997. The 11 1/4% Notes were issued at a substantial discount from
     their principal amount and mature on July 15, 2007.  Cash interest does not
     accrue on the 11 1/4% Notes prior to July 15, 2002. Commencing January 15,
     2003, cash interest on the 11 1/4% Notes will be payable semi-annually in
     arrears on July 15 and January 15 of each year at a rate of 11 1/4% per
     annum. The 11 1/4% Notes may be redeemed at the Company's option at any
     time, in whole or in part, on or after July 15, 2002  upon payment of the
     redemption price plus accrued and unpaid interest, if any, to the date of
     redemption. The 11 1/4% Notes are unsecured obligations of the Company
     ranking pari passu in right of payment of principal and interest with all
     other existing and future senior indebtedness of the Company, including the
     8 7/8% Notes, the 12 1/2% Notes and the 8 1/2% Notes, and rank senior to
     any future subordinated indebtedness. In the event of a change of control
     of the Company prior to July 15, 2002, holders of the 11 1/4% Notes have
     the right to require the Company to repurchase their 11 1/4% Notes, in

     101% of the principal amount thereof, plus accrued and unpaid interest, if
     any, to the date of purchase.

       The covenants in the 11 1/4% Notes Indenture are substantially similar to
     the covenants in the indentures for the 12 1/2%Notes and the 8 7/8% Notes
     and are substantially similar (with modifications to certain definitions
     and exceptions) to the covenants in the 8 1/2% Notes Indenture.  The 11
     1/4% Notes Indenture contains certain covenants that, among other things,
     limit the ability of the Company and its subsidiaries to make certain
     restricted payments, incur additional indebtedness and issue preferred
     stock, pay dividends or make other distributions, repurchase equity
     interests or subordinated indebtedness, engage in sale and leaseback
     transactions, create certain liens, enter into certain transactions with
     affiliates, sell assets of the Company or its subsidiaries, conduct certain
     lines of business, issue or sell equity interests of the Company's
     subsidiaries or enter into certain mergers and consolidations. In addition,
     under certain circumstances, the Company is required to offer to purchase
     11 1/4% Notes at a price equal to 100% of the accreted value thereof, if
     such circumstances occur prior to July 15, 2002, or at 100% of the
     principal amount thereof, if such circumstances occur on or after July 15,
     2002, plus accrued and unpaid interest, if any, to the date of purchase
     with the proceeds of certain asset sales. This description of the 11 1/4%
     Notes is intended as a summary and is qualified in its entirety by
     reference to the 11 1/4% Notes Indenture.

     8 7/8% NOTES

       The Company has outstanding an aggregate principal amount of $260,250,000
     of 8 7/8% Senior Notes due 2007 (the "8 7/8% Notes), which will mature on

     any time, in whole or in part, on or after November 1, 2002 upon payment of
     the redemption price plus accrued and unpaid interest, if any, to the date
     of redemption. The 8 7/8% Notes are unsecured obligations of the Company
     ranking pari passu in right of payment of principal and interest with all
     other existing and future senior indebtedness of the Company, including the
     12 1/2% Notes, the 11 1/4% Notes and the 8 1/2% Notes, and rank senior to
     any future subordinated indebtedness. In the event of a change of control
     of the Company, holders of the 8 7/8% Notes have the right to require the

     equal to 101% of the principal amount thereof, plus accrued and unpaid
     interest, if any, to the date of purchase.

     of Common Stock do not have cumulative rights, so that holders of more than

     Intermedia's Certificate of Incorporation and Bylaws." Subject to the
     preferences that may be applicable to any then outstanding Preferred Stock,

     dissolution or winding up, whether voluntary or involuntary, of Intermedia,
     holders of Common Stock are entitled to receive pro rata all assets
     available for distribution to stockholders after payment or provision for
     payment of the debts and other liabilities of Intermedia and the
     liquidation preferences of any then outstanding Preferred Stock. There are
     no preemptive or other subscription rights, conversion rights, or
     redemption or sinking fund provisions with respect to shares of Common
     Stock. All outstanding shares of Common Stock are, and all shares of Common
     Stock to be outstanding upon exercise of the Public Warrants and conversion
     of the Depositary Shares or shares of Series D Preferred Stock or Series E
     Preferred Stock will be, fully paid and non-assessable.

          The Preferred Stock may be issued at any time or from time to time in
     one or more series with such designations, powers, preferences, rights,

     differ from the terms set forth below.

     DEPOSITARY SHARES

          General.  The following summary is qualified in its entirety by
     reference to the applicable Deposit Agreement or form of Depositary
     Receipt.  The Company may, at its option, elect to offer fractional shares
     or some multiple of shares of Preferred Stock, rather than individual
     shares of Preferred Stock.  In the event such option is exercised, the
     Company will issue receipts for Depositary Shares, each of which will
     represent a fraction or a multiple (to be set forth in the Prospectus
     Supplement relating to a particular series of offered Preferred Stock) of a
     share of a particular series of offered Preferred Stock as described below.

          The shares of any series of offered Preferred Stock represented by
     Depositary Shares will be deposited under a Deposit Agreement (the "Deposit
     Agreement") among the Company, a depositary agent to be determined by the
     Company, as depositary (the "Preferred Stock Depositary"), and the holders
     from time to time of depositary receipts issued thereunder.  Subject to the
     terms of the Deposit Agreement, each holder of a Depositary Share will be
     entitled, in proportion to the applicable fraction or multiple of a share
     of Preferred Stock represented by such Depositary Share, to all the rights
     and preferences of the Preferred Stock represented thereby (including
     dividend, voting and liquidation rights).

                                       27
<PAGE>
 
          The Depositary Shares will be evidenced by depositary receipts issued
     pursuant to the Deposit Agreement ("Depositary Receipts").  Depositary
     Receipts will be distributed to those persons purchasing the fractional or
     multiple shares of the related series of Preferred Stock.  Immediately
     following the issuance of shares of a series of Preferred Stock by the
     Company, the Company will deposit such shares with the Preferred Stock
     Depositary, which will then issue and deliver the Depositary Receipts to
     the purchasers thereof. Depositary Receipts will only be issued evidencing
     whole Depositary Shares.  A Depositary Receipt may evidence any number of
     whole Depositary Shares.

          Pending the preparation of definitive engraved Depositary Receipts,
     the Preferred Stock Depositary may, upon the written order of the Company,
     issue temporary Depositary Receipts substantially identical to (and
     entitling the holders thereof to all the rights pertaining to) the
     definitive Depositary Receipts but not in definitive form.  Definitive
     Depositary Receipts will be prepared thereafter without unreasonable delay,
     and such temporary Depositary Receipts will be exchangeable for definitive
     Depositary Receipts at the Company's expense.

          Dividends and Other Distributions.  The Preferred Stock Depositary
     will distribute all cash dividends or other cash distributions received in
     respect of the related series of Preferred Stock to the record holders of
     Depositary Shares relating to such series of Preferred Stock in proportion
     to the number of such Depositary Shares owned by such holders.

          In the event of a distribution other than in cash, the Preferred Stock
     Depositary will distribute property received by it to the record holders of
     Depositary Shares entitled thereto in proportion to the number of
     Depositary Shares owned by such holders, unless the Preferred Stock
     Depositary determines that such distribution cannot be made proportionately
     among such holders or that it is not feasible to make such distribution, in
     which case the Preferred Stock Depositary may, with the approval of the
     Company, sell such property and distribute the net proceeds from such sale
     to such holders in proportion to the number of Depositary Shares owned by
     such holders.

          The amount distributed in any of the foregoing cases will be reduced
     by any amounts required to be withheld by the Company or the Preferred
     Stock Depositary on account of taxes or other governmental charges.

          Withdrawal of Stock.  Upon surrender of the Depositary Receipts at the
     corporate trust office of the Preferred Stock Depositary and upon payment
     of the taxes, charges and fees provided for in the Deposit Agreement and
     subject to the terms thereof, the holder of the Depositary Shares evidenced
     thereby is entitled to delivery at such office, to or upon his or her
     order, of the number of whole shares of the related series of Preferred
     Stock and any money or other property, if any, represented by such
     Depositary Shares.  Holders of Depositary Shares will be entitled to
     receive whole shares of the related series of Preferred Stock, but holders
     of such whole shares of Preferred Stock will not thereafter be entitled to
     deposit such shares of Preferred Stock with the Preferred Stock Depositary
     or to receive Depositary Shares therefor.  If the Depositary Receipts
     delivered by the holder evidence a number of Depositary Shares in excess of
     the number of Depositary Shares representing the number of whole shares of
     the related series of Preferred Stock to be withdrawn, the Preferred Stock
     Depositary will deliver to such holder, or upon his or her order, at the
     same time a new Depositary Receipt evidencing such excess number of
     Depositary Shares.

          Voting the Preferred Stock.  Upon receipt of notice of any meeting at
     which the holders of any series of the Preferred Stock are entitled to
     vote, the Preferred Stock Depositary will mail the information contained in
     such notice of meeting to the record holders of the Depositary Shares
     relating to such series of Preferred Stock. Each record holder of such
     Depositary Shares on the record date (which will be the same date as the
     record date for the related series of Preferred Stock) will be entitled to
     instruct the Preferred Stock Depositary as to the exercise of the voting
     rights pertaining to the number of shares of the series of Preferred Stock
     represented by such holder's Depositary Shares.  The Preferred Stock
     Depositary will endeavor, insofar as practicable, to vote or cause to be
     voted the number of shares of the Preferred Stock represented by such
     Depositary Shares in

                                       28
<PAGE>
 
     accordance with such instructions, provided the Preferred Stock Depositary
     receives such instructions sufficiently in advance of such meeting to
     enable it to so vote or cause to be voted the shares of Preferred Stock,
     and the Company will agree to take all reasonable action that may be deemed
     necessary by the Preferred Stock Depositary in order to enable the
     Preferred Stock Depositary to do so.  The Preferred Stock Depositary will
     abstain from voting shares of the Preferred Stock to the extent it does not
     receive specific instructions from the holders of Depositary Shares
     representing such Preferred Stock.

          Redemption of Depositary Shares.  If a series of the Preferred Stock
     underlying the Depositary Shares is subject to redemption, the Depositary
     Shares will be redeemed from the proceeds received by the Preferred Stock
     Depositary resulting from any redemption, in whole or in part, of such
     series of the Preferred stock held by the Preferred Stock Depositary.  The
     redemption price per Depositary Share will be equal to the applicable
     fraction or multiple of the redemption price per share payable with respect
     to such series of the Preferred Stock.  If the Company redeems shares of a
     series of Preferred Stock held by the Preferred Stock Depositary, the
     Preferred Stock Depositary will redeem as of the same redemption date the
     number of Depositary Shares representing the shares of Preferred Stock so
     redeemed.  If less than all the Depositary Shares are to be redeemed, the
     Depositary Shares to be redeemed will be selected by lot or substantially
     equivalent method determined by the Preferred Stock Depositary.

          After the date fixed for redemption, the Depositary Shares so called
     for redemption will no longer be deemed to be outstanding and all rights of
     the holders of the Depositary Shares will cease, except the right to
     receive the moneys payable upon such redemption and any money or other
     property to which the holders of such Depositary Shares were entitled upon
     such redemption, upon surrender to the Preferred Stock Depositary of the
     Depositary Receipts evidencing such Depositary Shares.  Any funds deposited
     by the Preferred Stock Depositary for any Depositary Shares that the
     holders thereof fail to redeem will be returned to the Company after a
     period of two years from the date such funds are so deposited.

          Amendment and Termination of the Deposit Agreement.  The form of
     Depositary Receipt evidencing the Depositary Shares and any provision of
     the Deposit Agreement may at any time and from time to time be amended by
     the Company and the Preferred Stock Depositary.  However, any amendment
     that materially and adversely alters the rights of the holders of
     Depositary Shares will not be effective unless such amendment has been
     approved by the holders of at least a majority of the Depositary Shares
     then outstanding.  Notwithstanding the foregoing, in no event may any
     amendment impair the right of any holder of any Depositary Shares, upon
     surrender of the Depositary Receipts evidencing such Depositary Shares and
     subject to any conditions specified in the Deposit Agreement, to receive
     shares of the related series of Preferred Stock and any money or other
     property represented thereby, except in order to comply with mandatory
     provisions of applicable law.  The Deposit Agreement may be terminated by
     the Company at any time upon not less than 60 days' prior written notice to
     the Preferred Stock Depositary, in which case, on a date that is not later
     than 30 days after the date of such notice, the Preferred Stock Depositary
     shall deliver or make available for delivery to holders of Depositary
     Shares, upon surrender of the Depositary Receipts evidencing such
     Depositary Shares, such number of whole or fractional shares of the related
     series of Preferred Stock as are represented by such Depositary Shares.
     The Deposit Agreement shall automatically terminate after there has been a
     final distribution in respect of the related series of Preferred Stock in
     connection with any liquidation, dissolution or winding up of the Company
     and such distribution has been distributed to the holders of Depositary
     Shares.

          Charges of Preferred Stock Depositary.  The Company will pay all
     transfer and other taxes and governmental charges arising solely from the
     existence of the depositary arrangements.  The Company will pay charges of
     the Preferred Stock Depositary, including charges in connection with the
     initial deposit of the related series of Preferred Stock and the initial
     issuance of the Depositary Shares and all withdrawals of shares of the
     related series of Preferred Stock, except that holders of Depositary Shares
     will pay other transfer and other taxes and governmental charges and such
     other charges as are expressly provided in the Deposit Agreement to be for
     their accounts.

                                       29
<PAGE>
 
          Miscellaneous.  The Preferred Stock Depositary will forward to the
     holders of Depositary Shares all reports and communications from the
     Company that are delivered to the Preferred Stock Depositary and which the
     Company is required to furnish to the holders of the Preferred Stock.

          Neither the Preferred Stock Depositary nor the Company will be liable
     if it is prevented or delayed by law or any circumstance beyond its control
     in performing its obligations under the Deposit Agreement.  The obligations
     of the Company and the Preferred Stock Depositary under the Deposit
     Agreement will be limited to performance with best judgment and in good
     faith of their duties thereunder, except that they are liable for
     negligence and willful misconduct in the performance of their duties
     thereunder, and they will not be obligated to appear in, prosecute or
     defend any legal proceeding in respect of any Depositary Receipts,
     Depositary Shares or series of Preferred Stock unless satisfactory
     indemnity is furnished.  The Preferred Stock Depositary and the Company may
     rely on advice of legal counsel or accountants of their choice, or
     information provided by persons presenting Preferred Stock for deposit,
     holders of Depositary Shares or other persons believed in good faith to be
     competent and on documents believed to be genuine.

          The Preferred Stock Depositary's corporate trust office is currently
     located at 2 Broadway, New York, New York 10004.  The Preferred Stock
     Depositary will act as transfer agent and registrar for Depositary Receipts
     and if shares of a series of Preferred Stock are redeemable, the Preferred
     Stock Depositary will act as redemption agent for the corresponding
     Depositary Receipts.

          Resignation and Removal of Preferred Stock Depositary.  The Preferred
     Stock Depositary may resign at any time by delivering to the Company
     written notice of its election to do so, and the Company may at any time
     remove the Preferred Stock Depositary, any such resignation or removal to
     take effect upon the appointment of a successor Preferred Stock Depositary,
     which successor Preferred Stock Depositary must be appointed within 60 days
     after delivery of the notice of resignation or removal and must be a bank
     or trust company having its principal office in the United States and
     having a combined capital and surplus of at least $50,000,000.

     SERIES B PREFERRED STOCK

          As of November 30, 1997, the Company had outstanding 323,499.1404
     shares of Series B Preferred Stock (aggregate liquidation preference of
     approximately $323.5 million). Dividends on the Series B Preferred Stock
     accumulate at a rate of 13 1/2% of the aggregate liquidation preference
     thereof and are payable quarterly, in arrears. Dividends are payable in
     cash or, at the Company's option, by the issuance of additional Series B
     Preferred Stock having an aggregate liquidation preference equal to the
     amount of such dividends. The Series B Preferred Stock is subject to
     mandatory redemption at a liquidation preference of $1,000 per share, plus
     accumulated and unpaid dividends on March 31, 2009. The Series B Preferred
     Stock will be redeemable at the option of the Company at any time after
     March 31, 2002 at rates commencing with 106.75%, declining to 100% on March
     31, 2007. The Series B Certificate of Designation contains certain
     covenants that, among other things, limit the ability of the Company and
     its subsidiaries to make certain restricted payments, incur additional
     indebtedness and issue additional preferred stock, pay dividends or make
     other distributions, repurchase equity interests, conduct certain lines of
     business or enter into certain mergers and consolidations. In the event of
     a change of control of the Company, holders of the Series B Preferred Stock
     have the right to require the Company to purchase their shares of Series B
     Preferred Stock at a price equal to 101% of the aggregate liquidation
     preference with respect thereto, plus accumulated and unpaid dividends, if
     any, to the date of purchase. This description is intended as a summary and
     is qualified in its entirety by reference to the Series B Certificate of
     Designation.

          The Company may, at its option, exchange some or all of the Series B
     Preferred Stock for the Company's 13 1/2% Senior Subordinated Debentures,
     due 2009 (the "Exchange Debentures"). The Exchange Debentures would  mature
     on March 31, 2009. Interest on the Exchange Debentures would be payable
     semi-annually, and could be paid in the form of additional Exchange
     Debentures at the Company's option.

     Exchange Debentures would be redeemable by the Company at any time after
     March 31, 2002 at rates commencing with 106.75%, declining to 100% on March
     31, 2007. The Exchange Debentures contain covenants similar to those
     contained in the Indenture.

          As of November 30, 1997, the Company had outstanding 69,000 shares of

     rate of 7% of the aggregate liquidation preference thereof and are payable
     quarterly, in arrears, on each January 15, April 15, July 15 and October
     15.  Dividends are payable in cash or, at the Company's option, by the

     option of the holder, into Common Stock at a conversion price of $38.90 per
     share of Common Stock, subject to certain adjustments.  In the event of a
     change of control of the Company, holders of the Series D Preferred Stock
     have the right to require the Company to purchase their shares of Series D
     Preferred Stock at a price equal to 100% of the aggregate liquidation
     preference with respect thereto, plus accumulated and unpaid dividends and
     preferred stock liquidated damages, if any, to the date of purchase,
     subject to the restrictions on such repurchase contained in the Series B
     Preferred Stock Certificate of Designation and the outstanding indebtedness
     of the Company. This description is intended as a summary and is qualified
     in its entirety by reference to the Series D Certificate of Designation.

     December 29, 1997), at the option of the holder, into Common Stock at a
     conversion price of $60.47 per share of Common Stock, subject to certain
     adjustments. In the event of a change of control of the Company, holders of
     the Series E Preferred Stock have the right to require the Company to
     purchase their shares of Series E Preferred Stock at a price equal to 100%

     Preferred Stock and Series E Preferred Stock were held in the form of
     Depository Shares, each of which represents a one-hundredth interest in a
     share of Series D Preferred Stock or Series E Preferred Stock. Each owner
     of a Depositary Share is entitled proportionately to all of the rights and
     preferences of the shares of Series D Preferred Stock or Series E Preferred
     Stock represented thereby (including dividend, voting, redemption and
     liquidation rights) contained in the Company's Certificate of Incorporation
     and the Certificate of Designations and summarized above.

     DELAWARE LAW AND CERTAIN PROVISIONS OF INTERMEDIA'S CERTIFICATE OF
     INCORPORATION AND BYLAWS

                                       31

<PAGE>
 
          General. The Certificate of Incorporation and the Bylaws of Intermedia
     contain certain provisions that could make more difficult the acquisition
     of Intermedia by means of a tender offer, a proxy contest or otherwise.
     These provisions are expected to discourage certain types of coercive
     takeover practices and inadequate takeover bids and to encourage persons
     seeking to acquire control of Intermedia first to negotiate with
     Intermedia. Although such provisions may have the effect of delaying,
     deferring or preventing a change in control of Intermedia, the Company
     believes that the benefits of increased protection of Intermedia's
     potential ability to negotiate with the proponent of an unfriendly or
     unsolicited proposal to acquire or restructure the Company outweigh the
     disadvantages of discouraging such proposals because, among other things,
     negotiation of such proposals could result in an improvement of their
     terms. The description set forth below is intended as a summary only and is
     qualified in its entirety by reference to the Certificate of Incorporation
     and Bylaws of Intermedia.

          Board of Directors. Intermedia's Certificate of Incorporation provides
     that (i) the Board be divided into three classes of directors, with each
     class having a number as nearly equal as possible and with the term of each
     class expiring in a different year and (ii) the Board shall consist of not
     less than three nor more than seven members, the exact number to be
     determined from time to time by the Board. The Board has set the number of
     directors at four. Subject to any rights of holders of Preferred Stock, a
     majority of the Board then in office will have the sole authority to fill
     any vacancies on the Board. Stockholders can remove members of the Board
     only for cause.

          Stockholder Action and Special Meetings. Intermedia's Certificate of
     Incorporation provides that (i) any action required or permitted to be
     taken by Intermedia's stockholders must be effected at a duly called annual
     or special meeting of Stockholders and may not be effected by any consent
     in writing and (ii) the authorized number of directors may be changed only
     by resolution of the Board. The Company's Bylaws provide that, subject to
     any rights of holders of any series of Preferred Stock, special meetings of
     stockholders may be called only by the Chairman of the Board or the
     President of Intermedia, by a majority of the Board or by stockholders
     owning shares representing at least a majority of the capital stock of
     Intermedia issued and outstanding and entitled to vote.

          Stockholder's Rights Plan. Intermedia's Board of Directors has adopted
     a Stockholder's Rights Plan, pursuant to which rights to acquire the
     Company's Series C Preferred Stock, exercisable upon the occurrence of
     certain events, including the acquisition by a person or group of a
     specified percentage of the Common Stock, were distributed to its
     stockholders.

          Anti-Takeover Statute. Subject to certain exceptions, Section 203 of
     the DGCL prohibits a publicly held Delaware corporation, such as
     Intermedia, from engaging in any "business combination" with an "interested
     stockholder" for a three-year period following the date on which such
     person became an interested stockholder, unless (i) prior to such date, the
     board of directors of the corporation approved either such business
     combination or the transaction that resulted in such person becoming an
     interested stockholder, (ii) upon consummation of the transaction that
     resulted in such person becoming an interested stockholder, such person
     owned at least 85% of the voting stock of the corporation outstanding
     immediately prior to such transaction (excluding certain shares) or (iii)
     on or subsequent to such date, such business combination is approved by the
     board of directors of the corporation and by the affirmative vote of at
     least 66 2/3% of the outstanding voting stock that is not owned by the
     interested stockholder. A "business combination" includes a merger, asset
     sale or other transaction resulting in a financial benefit to the
     interested stockholder. An "interested stockholder" is essentially a person
     who, together with affiliates and associates, owns (or within the past
     three years has owned) 15% or more of the corporation's voting stock. It is
     anticipated that the provisions of Section 203 of the DGCL may encourage
     any person interested in acquiring Intermedia to negotiate in advance with
     the Board since the stockholder approval requirement would be avoided if a
     majority of Intermedia's directors then in office approved either the
     business combination or the transaction that resulted in such person
     becoming an interested stockholder.

     DIVIDEND RESTRICTIONS

          The terms of the Existing Indentures restrict the Company's ability to
     pay cash dividends on the Series B Preferred Stock.  The Existing
     Indentures and the Series B Certificate of Designation restrict
     Intermedia's ability to pay cash dividends on the Common Stock, the Series
     D Preferred Stock and the Series E Preferred Stock.

     TRANSFER AGENT AND REGISTRAR

          The transfer agent and registrar for the Common Stock, Series B
     Preferred Stock, the Series D Preferred Stock and the Series E Preferred
     Stock is Continental Stock Transfer & Trust Company.

     OUTSTANDING WARRANTS

          160,000 warrants (the "Public Warrants"), each to purchase 2.19 shares
     of Common Stock, at an exercise price of $10.86 per share (subject to anti-
     dilution adjustments) were issued as part of a June 1995 private placement.
     The Public Warrants are currently exercisable. Unless exercised, the Public
     Warrants will expire on June 1, 2000.

          Ralph J. Sutcliffe, a partner of Kronish, Lieb, Weiner & Hellman LLP,
     owns a warrant to purchase 100,000 shares of Common Stock at an exercise
     price of $41.50 per share.

          On January 13, 1998, the warrant owned by Current Science Group, Inc.,
     formerly known as Electronic Press Services Inc was exercised pursuant to a
     cashless exercise provision for 53,172 shares of Common Stock.

     RESERVATION OF SHARES

          The Company has authorized and reserved for issuance such number of
     Common Shares as will be issuable upon the exercise of all warrants and the
     conversion of all Depositary Shares (or all shares of the Series D
     Preferred Stock and Series E Preferred Stock).  Such Common Shares, when
     issued, will be duly and validly issued, fully paid and non-assessable,
     free of preemptive rights and free from all taxes, liens, charges and
     security interests with respect to the issue thereof.

     REGISTRATION RIGHTS

          The Company is a party to several agreements pursuant to which certain
     stockholders have the right, among other matters, to require the Company to
     register their shares of Common Stock under the Securities Act under
     certain circumstances. As a result, substantially all of the Company's
     outstanding shares, other than those held by affiliates, are transferable
     without restriction under the Securities Act.

                              PLAN OF DISTRIBUTION

          The Company may sell the Securities offered hereby (1) through
     underwriters or dealers; (2) through agents; (3) directly to purchasers, or
     (4) through a combination of any such methods of sale.  Any such
     underwriter, dealer or agent may be deemed to be an underwriter within the
     meaning of the Securities Act.  The Prospectus Supplement relating to the
     Securities will set forth their offering terms, including the name or names
     of any underwriters, dealers or agents, the purchase price of the
     Securities and the proceeds to the Company from such sale, any underwriting
     discounts, commissions and other items constituting compensation to
     underwriters, dealers or agents, any initial public offering price, any
     discounts or concessions allowed or reallowed or paid by underwriters or
     dealers to other dealers, and any securities exchanges on which the
     Securities may be listed.

          If underwriters or dealers are used in the sale, the Securities will
     be acquired by the underwriters or dealers for their own account and may be
     resold from time to time in one or more transactions, at a fixed price or
     prices, which may be changed, or at market prices prevailing at the time of
     sale, or at prices related to such prevailing market prices, or at
     negotiated prices.  The Securities may be offered to the public either
     through underwriting syndicates represented by one or more managing
     underwriters or directly by one or more of such firms.  Unless otherwise
     set forth in the Prospectus Supplement, the obligations of underwriters or
     dealers to purchase the Securities will be subject to certain conditions
     precedent and the underwriters or dealers will be obligated to purchase all
     the Securities if any are purchased.  Any initial public offering price and
     any discounts or concessions allowed or reallowed or paid by underwriters
     or dealers to other dealers may be changed from time to time.

          Securities may be sold directly by the Company or through agents
     designated by the Company from time to time.  Any agent involved in the
     offer or sale of the Securities in respect of which this Prospectus is
     delivered will be named, and any commissions payable by the Company to such
     agent will be set forth, in the Prospectus Supplement.  Unless otherwise
     indicated in the Prospectus Supplement, any such agent will be acting on a
     best efforts basis for the period of its appointment.

          If so indicated in the Prospectus Supplement, the Company will
     authorize underwriters, dealers or agents to solicit offers by certain
     specified institutions to purchase Securities from the Company at the
     public offering price set forth in the Prospectus Supplement pursuant to
     delayed delivery contracts providing for payment and delivery on a
     specified date in the future.  Such contracts will be subject to any
     conditions set forth in the Prospectus Supplement and the Prospectus
     Supplement will set forth the commission payable for solicitation of such
     contracts.  The underwriters and other persons soliciting such contracts
     will have no responsibility for the validity or performance of any such
     contracts.

          Underwriters, dealers and agents may be entitled under agreements
     entered into with the Company to indemnification by the Company against
     certain civil liabilities, including liabilities under the Securities Act,
     or to contribution by the Company to payments they may be required to make
     in respect thereof.  The terms and conditions of such indemnification will
     be described in an applicable Prospectus Supplement. Underwriters, dealers
     and agents may be customers of, engage in transactions with, or perform
     services for the Company in the ordinary course of business.

          Each series of Securities other than Common Stock will be a new issue
     of securities with no established trading market.  Any underwriters to whom
     Securities are sold by the Company for public offering and sale may make a
     market in such Securities, but such underwriters will not be obligated to
     do so and may discontinue any market making at any time without notice.  No
     assurance can be given as to the liquidity of the trading market for any
     Securities.

                   INFORMATION NOT REQUIRED IN THE PROSPECTUS

     ITEM 14.  Other Expenses of Issuance and Distribution.

          The following statement sets forth the expenses payable in connection
     with this Registration Statement (estimated except for the registration
     fee), all of which will be borne by the Company:

     Securities and Exchange Commission filing fee................  $147,500.00
     Legal fees and expenses......................................  $100,000.00
     Accountant's fees and expenses...............................  $ 14,000.00
     Miscellaneous................................................  $  8,500.00

     Total........................................................  $270,000.00

     ITEM 15.  Indemnification of Directors and Officers.

          The Company's Certificate of Incorporation provides that the Company
     will to the fullest extent permitted by the General Corporation Law of the
     State of Delaware (the "GCL"), as amended from time to time, indemnify all
     persons whom it may indemnify pursuant thereto.  The Company's By-laws
     contain a similar provision requiring indemnification of the Company's
     directors and officers to the fullest extent authorized by the GCL.  The
     GCL permits a corporation to indemnify its directors and officers (among
     others) against expenses (including attorneys' fees), judgments, fines and
     amounts paid in settlement actually and reasonably incurred by them in
     connection with any action, suit or proceeding brought (or threatened to be
     brought) by third parties, if such directors or officers acted in good
     faith and in a manner they reasonably believed to be in or not opposed to
     the best interests of the corporation and, with respect to any criminal
     action or proceeding, had no reasonable cause to believe their conduct was
     unlawful.  In a derivative action, i.e., one by or in the right of the
     corporation, indemnification may be made for expenses (including attorneys'
     fees) actually and reasonably incurred by directors and officers in
     connection with the defense or settlement of such action if they had acted
     in good faith and in a manner they reasonably believed to be in or not
     opposed to the best interests of the corporation, except that no
     indemnification shall be made in respect of any claim, issue or matter as
     to which such person shall have been adjudged liable to the Company unless
     and only to the extent that the Court of Chancery or the court in which
     such action or suit was brought shall determine upon application that,
     despite the adjudication of liability but in view of all the circumstances
     of the case, such person is fairly and reasonably entitled to indemnity for
     such expenses.  The GCL further provides that, to the extent any director
     or officer has been successful on the merits or otherwise in defense of any
     action, suit or proceeding referred to in this paragraph, or in defense of
     any claim, issue or matter therein, such person shall be indemnified
     against expenses (including attorneys' fees) actually and reasonably
     incurred by him in connection therewith.  In addition, the Company's
     Certificate of Incorporation contains a provision limiting the personal
     liability of the Company's directors for monetary damages for certain
     breaches of their fiduciary duty.  The Company has indemnification
     insurance under which directors and officers are insured against certain
     liability that may occur in their capacity as such.

     ITEM 17.  Undertakings.

              The undersigned registrant hereby undertakes:

        (1)  To file, during any period in which offers or sales are
being made, a post-effective amendment to this Registration Statement:

               (i)  To include any prospectus required by Section 10(a)(3) of
     the Securities Act;

               (ii) To reflect in the Prospectus any facts or events arising
     after the effective date of this Registration Statement (or the most recent
     post-effective amendment thereof) which, individually or in the aggregate,
     represent a fundamental change in the information set forth in this
     Registration Statement.

                                      II-2

<PAGE>
 
     Notwithstanding the foregoing, any increase or decrease in the volume of
     securities offered (if the total dollar value of securities offered would
     not exceed that which was registered) and any deviation from the low or
     high end of the estimated maximum offering range may be reflected in the
     form of prospectus filed with the Commission pursuant to Rule 424(b) if, in
     the aggregate, the changes in volume and price represent no more than a 20
     percent change in the maximum aggregate offering price set forth in the
     "Calculation of Registration Fee" table in the effective registration
     statement;

               (iii) To include any material information with respect to the
     plan of distribution not previously disclosed in this Registration
     Statement or any material change to such information in this Registration
     Statement;

     provided, however, that paragraphs (i) and (ii) above do not apply if the
     information required to be included in a post-effective amendment by those
     paragraphs is contained in periodic reports filed with or furnished to the
     Commission by the Company pursuant to Section 13 or Section 15(d) of the
     Exchange Act that are incorporated by reference in this Registration
     Statement.

               (2) That, for the purpose of determining any liability under the
     Securities Act, each such post-effective amendment shall be deemed to be a
     new registration statement relating to the securities offered therein, and
     the offering of such securities at that time shall be deemed to be the
     initial bona fide offering thereof.

               (3) To remove from registration by means of a post-effective
     amendment any of the securities being registered which remain unsold at the
     termination of the offering.

               (4) That, for purposes of determining any liability under the
     Securities Act, each filing of the registrant's annual report pursuant to
     Section 13(a) or Section 15(d) of the Exchange Act (and, where applicable,
     each filing of an employee benefit plan's annual report pursuant to Section
     15(d) of the Exchange Act) that is incorporated by reference in this
     Registration Statement shall be deemed to be a new registration statement
     relating to the securities offered therein, and the offering of such
     securities at that time shall be deemed to be the initial bona fide
     offering thereof.

               Insofar as indemnification for liabilities arising under the
     Securities Act may be permitted to directors, officers and controlling
     persons of the registrant pursuant to the foregoing provisions, or
     otherwise, the registrant has been advised that in the opinion of the
     Securities and Exchange Commission such indemnification is against public
     policy as expressed in the Securities Act and is, therefore, unenforceable.
     In the event that a claim for indemnification against such liabilities
     (other than the payment by registrant of expenses incurred or paid by a
     director, officer or controlling person of the registrant in the successful
     defense of any action, suit or proceeding) is asserted by such director,
     officer or controlling person in connection with the securities being
     registered, the registrant will, unless in the opinion of its counsel the
     matter has been settled by controlling precedent, submit to a court of
     appropriate jurisdiction the question whether such indemnification by it is
     against public policy as expressed in the Securities Act and will be
     governed by the final adjudication of such issue.

                                      II-3

as shall be given with the approval of the Trustee shall constitute sufficient
notice for every purpose hereunder.

          In the event of suspension of publication of any Authorized Newspapers
or by reason of any other cause it shall be impracticable to make any
publication of notice required by this Indenture in the manner prescribed

lithographed or engraved or produced by any combination of these methods on
steel engraved borders or may be produced in any other manner, all as determined
by the officers executing such Debt Securities as conclusively evidenced by
their execution of such Debt Securities.

          Section 2.03. Securities in Global Form.
                        ------------------------- 

          If any Debt Security of a series is issuable in global form (a "Global
Note"), such Global Note may provide that it shall represent the aggregate
amount of Outstanding Debt Securities from time to time endorsed thereon and may
also provide that the aggregate amount of Outstanding Debt Securities
represented thereby may from time to time be reduced to reflect exchanges.  Any
endorsement of a Global Note to reflect the amount, or any increase or decrease
in the amount, of Outstanding Debt Securities represented thereby shall be made
by the Trustee and in such manner as shall be specified in such Global Note.
Any instructions by the Company with respect to a Global Note, after its initial
issuance, shall be in writing but need not comply with Section 1.02.

          Global Notes may be issued in registered form and in either temporary
or permanent form.  Permanent Global Notes will be issued in definitive form.

          All Debt Securities of any one series shall be substantially identical
except as to denomination, rate of interest, Stated Maturity and the date from
which interest, if any, shall accrue, which, as set forth above, may be

          If any of the terms of a series of Debt Securities is established in

          Section 3.02. Denominations.
                        ------------- 

          In the absence of any specification pursuant to Section 3.01 with
respect to the Debt Securities of any series, the Debt Securities of such series
shall be issuable only as Registered Securities in denominations of $1,000 and
any integral multiple thereof and shall be payable only in Dollars.

          Section 3.03. Execution, Authentication, Delivery and Dating.
                        ---------------------------------------------- 

          The Debt Securities of any series shall be executed on behalf of the
Company by its Chairman, a Vice Chairman, its President, one of its Vice
Presidents or its Treasurer, under its corporate seal reproduced thereon and
attested by its Secretary or one of its Assistant Secretaries.  The signature of
any of these officers may be manual or facsimile.

          Debt Securities bearing the manual or facsimile signatures of
individuals who were at any time the proper officers of the Company shall bind
the Company, notwithstanding that such individuals

                                       17
<PAGE>
 
or any of them have ceased to hold such offices prior to the authentication and
delivery of such Debt Securities or did not hold such offices at the date of
such Debt Securities.

          At any time and from time to time after the execution and delivery of
this Indenture, the Company may deliver Debt Securities of any series, executed
by the Company, to the Trustee for authentication, together with a Company Order
for the authentication and delivery of such Debt Securities and the Trustee in
accordance with the Company Order shall authenticate and deliver such Debt
Securities.  If all the Debt Securities of any one series are not to be issued
at one time and if a Board Resolution or supplemental indenture relating to such
series shall so permit, such Company Order may set forth procedures acceptable
to the Trustee for the issuance of such Debt Securities such as interest rate,
Stated Maturity, date of issuance and date from which interest, if any, shall
accrue.  If any Debt Security shall be represented by a permanent Global Note,
then, for purposes of this Section and Section 3.04, the notation of a
beneficial owner's interest therein upon original issuance of such Debt Security
or upon exchange of a portion of a temporary Global Note shall be deemed to be
delivery in connection with the original issuance of such beneficial owner's
interest in such permanent Global Note.

          The Trustee shall be entitled to receive, and (subject to Section
6.01) shall be fully protected in relying upon, prior to the authentication and
delivery of the Debt Securities of such series, (i) the supplemental indenture
or the Board Resolution by or pursuant to which the form and terms of such Debt
Securities have been approved and (ii) an Opinion of Counsel substantially to
the effect that:

          (1) all instruments furnished by the Company to the Trustee in
     connection with the authentication and delivery of such Debt Securities
     conform to the requirements of this Indenture and constitute sufficient
     authority hereunder for the Trustee to authenticate and deliver such Debt
     Securities;

          (2) the forms and terms of such Debt Securities have been established
     in conformity with the provisions of this Indenture;

          (3) in the event that the forms or terms of such Debt Securities have
     been established in a supplemental indenture, the execution and delivery of
     such supplemental indenture has been duly authorized by all necessary
     corporate action of the Company, such supplemental  indenture has been duly
     executed and delivered by the Company and, assuming due authorization,
     execution and delivery by the Trustee, is a valid and binding obligation
     enforceable against the Company in accordance with its terms, subject to
     applicable bankruptcy, insolvency and similar laws affecting creditors'
     rights generally and subject, as to enforceability, to general principles
     of equity (regardless of whether enforcement is sought in a proceeding in
     equity or at law);

          (4) the execution and delivery of such Debt Securities have been duly
     authorized by all necessary corporate action of the Company and such Debt
     Securities have been duly executed by the Company and, assuming due
     authentication by the Trustee and delivery by the Company, are valid and
     binding obligations enforceable against the Company in accordance with
     their terms, entitled to the benefit of the Indenture, subject to
     applicable bankruptcy, insolvency and similar laws affecting creditors'
     rights generally and subject, as to enforceability, to general principles
     of equity (regardless of whether enforcement is sought in a proceeding in
     equity or at law) and subject to such other exceptions as counsel shall
     request and as to which the Trustee shall not reasonably object; and

                                       18
<PAGE>
 
          (5) the amount of Debt Securities Outstanding of such series, together
     with the amount of such Debt Securities, does not exceed any limit
     established under the terms of this Indenture on the amount of Debt
     Securities of such series that may be authenticated and delivered.

          The Trustee shall not be required to authenticate such Debt Securities
if the issuance of such Debt Securities pursuant to this Indenture will affect
the Trustee's own rights, duties or immunities under the Debt Securities and
this Indenture in a manner which is not reasonably acceptable to the Trustee.

          Each Registered Security shall be dated the date of its
authentication.

          No Debt Security shall be entitled to any benefit under this Indenture
or be valid or obligatory for any purpose unless there appears on such Debt
Security a certificate of authentication substantially in one of the forms
provided for herein duly executed by the Trustee or by an Authenticating Agent,
and such certificate upon any Debt Security shall be conclusive evidence, and
the only evidence, that such Debt Security has been duly authenticated and
delivered hereunder and is entitled to the benefits of this Indenture.
Notwithstanding the foregoing, if any Debt Security shall have been duly
authenticated and delivered hereunder but never issued and sold by the Company,
and the Company shall deliver such Debt Security to the Trustee for cancellation
as provided in Section 3.08 together with a written statement (which need not
comply with Section 1.02) stating that such Debt Security has never been issued
and sold by the Company, for all purposes of this Indenture such Debt Security
shall be deemed never to have been authenticated and delivered hereunder and
shall never be entitled to the benefits of this Indenture.

          Section 3.04. Temporary Debt Securities; Global Notes Representing
                        ----------------------------------------------------
Registered Securities.
- --------------------- 

          (a) Pending the preparation of definitive Registered Securities of any
series, the Company may execute, and upon receipt by the Trustee of a Company
Order and satisfaction by the Company of the conditions precedent set forth
herein the Trustee shall authenticate and deliver, temporary Registered
Securities which are printed, lithographed, typewritten, mimeographed or
otherwise produced, in any authorized denomination for Registered Securities of
such series, substantially of the tenor of the definitive Registered Securities
in lieu of which they are issued and with such appropriate insertions,
omissions, substitutions and other variations as the officers executing such
Registered Securities may determine, as conclusively evidenced by their
execution of such Registered Securities.  Every such temporary Registered
Security shall be executed by the Company and shall be authenticated and
delivered by the Trustee in accordance with Section 3.03 and upon the same
conditions and in substantially the same manner, and with the same effect, as
the definitive Registered Securities in lieu of which they are issued.

          Except in the case of temporary Debt Securities in global form (which
shall be exchanged in accordance with the provisions of the following
paragraphs), if temporary Debt Securities of any series are issued, the Company
will cause definitive Debt Securities of such series to be prepared without
unreasonable delay.  After the preparation of definitive Debt Securities of such
series, the temporary Debt Securities of such series shall be exchangeable for
definitive Debt Securities of such series, of a like Stated Maturity and with
like terms and provisions, upon surrender of the temporary Debt Securities of
such series at the office or agency of the Company in a Place of Payment for
such series, without charge to the Holder, except as provided in Section 3.05 in
connection with a transfer.  Upon surrender for cancellation of any one or more
temporary Debt Securities of any series, the Company shall execute and the
Trustee shall authenticate and deliver, in accordance with Section 3.03, in
exchange therefor a like

                                       19
<PAGE>
 
principal amount of definitive Debt Securities of the same series of authorized
denominations and of a like Stated Maturity and like terms and provisions.
Until so exchanged, the temporary Registered Securities of any series shall in
all respects be entitled to the same benefits under this Indenture as definitive
Registered Securities of such series.

          (b) If the Company shall establish pursuant to Section 3.01 that the
Registered Securities of a series are to be issued in whole or in part in the
form of one or more Global Notes, then the Company shall execute and the Trustee
shall, in accordance with Section 3.03 and the Company Order with respect to
such series, authenticate and deliver one or more Global Notes in temporary or
permanent form that (i) shall represent and shall be denominated in an amount
equal to the aggregate principal amount of the Outstanding Debt Securities of
such series to be represented by one or more Global Notes, (ii) shall be
registered in the name of the U.S. Depositary for such Global Note or Notes or
the nominee of such depositary, and (iii) shall bear a legend substantially to
the following effect: "This Debt Security may not be transferred except as a
whole by the Depositary to a nominee of the Depositary or by a nominee of the
Depositary to the Depositary or another nominee of the Depositary or by the
Depositary or any such nominee to a successor Depositary or a nominee of such
successor Depositary, unless and until this Debt Security is exchanged in whole
or in part for Debt Securities in definitive form."

          Notwithstanding any other provision of this Section or Section 3.05,
unless and until it is exchanged in whole or in part for Registered Securities
in definitive form, a Global Note representing all or a portion of the
Registered Securities of a series may not be transferred except as a whole by
the U.S. Depositary for such series to a nominee of such depositary or by a
nominee of such depositary to such depositary or another nominee of such
depositary or by such depositary or any such nominee to a successor U.S.
Depositary for such series or a nominee of such successor depositary.

          If at any time the U.S. Depositary for the Debt Securities of a series
notifies the Company that it is unwilling or unable to continue as U.S.
Depositary for the Debt Securities of such series or if at any time the U.S.
Depositary for Debt Securities of a series shall no longer be a clearing agency
registered and in good standing under the Securities Exchange Act of 1934, as
amended, or other applicable statute or regulation, the Company shall appoint a
successor U.S. Depositary with respect to the Debt Securities of such series.
If a successor U.S. Depositary for the Debt Securities of such series is not
appointed by the Company within 90 days after the Company receives such notice
or becomes aware of such condition, the Company will execute, and the Trustee,
upon receipt of a Company Order for the authentication and delivery of
definitive Debt Securities of such series, will authenticate and deliver,
Registered Securities of such series in definitive form in an aggregate
principal amount equal to the principal amount of the Global Note or Notes
representing such series in exchange for such Global Note or Notes.

          The Company may at any time and in its sole discretion determine that
the Registered Securities of any series issued in the form of one or more Global
Notes shall no longer be represented by such Global Note or Notes.  In such
event, the Company will execute, and the Trustee, upon receipt of a Company
Order for the authentication and delivery of definitive Debt Securities of such
series, will in accordance with Section 3.03 authenticate and deliver,
Registered Securities of such series in definitive form and in an aggregate
principal amount equal to the principal amount of the Global Note or Notes
representing such series in exchange for such Global Note or Notes.

          If the Registered Securities of any series shall have been issued in
the form of one or more Global Notes and if an Event of Default with respect to
the Debt Securities of such series shall have

                                       20
<PAGE>
 
occurred and be continuing, the Company will promptly execute, and the Trustee,
upon receipt of a Company Order for the authentication and delivery of
definitive Debt Securities of such series, will in accordance with Section 3.03
authenticate and deliver, Registered Securities of such series in definitive
form and in an aggregate principal amount equal to the principal amount of the
Global Note or Notes representing such series in exchange for such Global Note
or Notes.

          If specified by the Company pursuant to Section 3.01 with respect to
Registered Securities of a series, the U.S. Depositary for such series of
Registered Securities may surrender a Global Note for such series of Debt
Securities in exchange in whole or in part for Registered Securities of such
series in definitive form on such terms as are acceptable to the Company and
such depositary.  Thereupon, the Company shall execute and the Trustee shall in
accordance with Section 3.03 authenticate and deliver, without charge:

          (i) to each Person specified by the U.S. Depositary a new Registered
     Security or Securities of the same series, of any authorized denomination
     as requested by such Person in an aggregate principal amount equal to and
     in exchange for such Person's beneficial interest in the Global Note; and

          (ii) to the U.S. Depositary a new Global Note in a denomination equal
     to the difference, if any, between the principal amount of the surrendered
     Global Note and the aggregate principal amount of Registered Securities
     delivered to Holders thereof.

          Upon the exchange of a Global Note for Registered Securities in
definitive form, such Global Note shall be cancelled by the Trustee.  Debt
Securities issued in exchange for a Global Note pursuant to this subsection (c)
shall be registered in such names and in such authorized denominations as the
U.S. Depositary for such Global Note, pursuant to instructions from its direct
or indirect participants or otherwise, shall instruct the Trustee.  The Trustee
shall deliver such Debt Securities to the Persons in whose names such Debt
Securities are so registered.

          Section 3.05. Registration, Transfer and Exchange.
                        ----------------------------------- 

          (a) The Company shall cause to be kept at the Corporate Trust Office
of the Trustee a register (the registers maintained in such office and in any
other office or agency of the Company in a Place of Payment being herein
sometimes collectively referred to as the "Security Register") in which, subject
to such reasonable regulations as it may prescribe, the Company shall provide
for the registration of Registered Securities and of transfers and exchanges of
Registered Securities.  The Trustee is hereby appointed "Security Registrar" for
the purpose of registering Registered Securities and registering transfers and
exchanges of Registered Securities as herein provided; provided, however, that
                                                       --------  -------      
the Company may appoint co-Security Registrars or the terms of any series of
Debt Securities may provide otherwise.

          Upon surrender for registration of transfer of any Registered Security
of any series at the office or agency of the Company maintained for such
purpose, the Company shall execute, and the Trustee shall authenticate and
deliver, in the name of the designated transferee, one or more new Registered
Securities of the same series of like aggregate principal amount of such
denominations as are authorized for Registered Securities of such series and of
a like Stated Maturity and with like terms and conditions.

          Except as otherwise provided in Section 3.04 and this Section 3.05, at
the option of the Holder, Registered Securities of any series may be exchanged
for other Registered Securities of the same series of like aggregate principal
amount and of a like Stated Maturity and with like terms and conditions, upon
surrender of the Registered Securities to be exchanged at such office or agency.
Whenever any Registered Securities are surrendered for exchange, the Company
shall execute, and the Trustee shall authenticate and deliver in accordance with
Section 3.03, the Registered Securities which the Holder making the exchange is
entitled to receive.

          (b) All Debt Securities issued upon any transfer or exchange of Debt
Securities shall be valid obligations of the Company, evidencing the same debt,
and entitled to the same benefits under this Indenture, as the Debt Securities
surrendered for such transfer or exchange.

          Every Registered Security presented or surrendered for transfer or
exchange shall (if so required by the Company or the Trustee) be duly endorsed,
or be accompanied by a written instrument of transfer in form satisfactory to
the Company and the Security Registrar, duly executed, by the Holder thereof or
his attorney duly authorized in writing.

          No service charge will be made for any transfer or exchange of Debt
Securities except as provided in Section 3.06.  The Company may require payment
of a sum sufficient to cover any tax or other governmental charge that may be
imposed in connection with any registration, transfer or exchange of Debt
Securities, other than those expressly provided in this Indenture to be made at
the Company's own expense or without expense or without charge to the Holders.

          The Company shall not be required (i) to register, transfer or
exchange Debt Securities of any series during a period beginning at the opening
of business 15 days before the day of the transmission of a notice of redemption
of Debt Securities of such series selected for redemption under Section 13.03
and ending at the close of business on the day of such transmission, or (ii) to
register, transfer or exchange any Debt Security so selected for redemption in
whole or in part, except the unredeemed portion of any Debt Security being
redeemed in part.

          Section 3.06. Mutilated, Destroyed, Lost and Stolen Debt Securities.
                        ----------------------------------------------------- 

          If (i) any mutilated Debt Security is surrendered to the Trustee at
its Corporate Trust Office or (ii) the Company and the Trustee receive evidence
to their satisfaction of the destruction, loss or theft of any Debt Security and
there is delivered to the Company and the Trustee such security or indemnity as
may be required by them to save each of them and any Paying Agent harmless, and
neither the Company nor the Trustee receives actual notice that such Debt
Security has been acquired by a bona fide purchaser, then the Company shall
execute and upon Company Request the Trustee shall authenticate and deliver, in
exchange for or in lieu of any such mutilated, destroyed, lost or stolen Debt
Security, a new Debt Security of the same series of like Stated Maturity and
with like terms and conditions and like principal amount, bearing a number not
contemporaneously Outstanding, and that neither gain nor loss in interest shall
result from such exchange or substitution.

          In case any such mutilated, destroyed, lost or stolen Debt Security
has become or is about to become due and payable, the Company in its discretion
may, instead of issuing a new Debt Security, pay the amount due on such Debt
Security in accordance with its terms;

          Upon the issuance of any new Debt Security under this Section, the
Company may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in

                                       22
<PAGE>
 
respect thereto and any other expenses (including the fees and expenses of the
Trustee) connected therewith.

          Every new Debt Security of any series issued pursuant to this Section
shall constitute an original additional contractual obligation of the Company,
whether or not the destroyed, lost or stolen Debt Security shall be at any time
enforceable by anyone, and shall be entitled to all the benefits of this
Indenture equally and proportionately with any and all other Debt Securities of
that series duly issued hereunder.

          The provisions of this Section are exclusive and shall preclude (to
the extent lawful) all other rights and remedies with respect to the replacement
or payment of mutilated, destroyed, lost or stolen Debt Securities.

          Section 3.07. Payment of Interest; Interest Rights Preserved.
                        ---------------------------------------------- 

          (a) Interest on any Registered Security which is payable and is
punctually paid or duly provided for on any Interest Payment Date shall be paid
to the Person in whose name such Registered Security (or one or more Predecessor
Securities) is registered at the close of business on the Regular Record Date
for such interest notwithstanding the cancellation of such Registered Security
upon any transfer or exchange subsequent to the Regular Record Date.  Unless
otherwise specified as contemplated by Section 3.01 with respect to the Debt
Securities of any series, payment of interest on Registered Securities shall be
made at the place or places specified pursuant to Section 3.01 or, at the option
of the Company, by check mailed to the address of the Person entitled thereto as
such address shall appear in the Security Register or, if provided pursuant to
Section 3.01, by wire transfer to an account designated by the Registered
Holder.

          (b) Any interest on any Debt Security which is payable but is not
punctually paid or duly provided for on any Interest Payment Date (herein called
"Defaulted Interest") shall, if such Debt Security is a Registered Security,
forthwith cease to be payable to the Registered Holder on the relevant Regular
Record Date by virtue of his having been such Registered Holder, and such
Defaulted Interest may be paid by the Company, at its election in each case, as
provided in clause (1) or (2) below:

          (1) The Company may elect to make payment of any Defaulted Interest to
     the Persons in whose names such Registered Securities (or their respective
     Predecessor Securities) are registered at the close of business on a
     Special Record Date for the payment of such Defaulted Interest, which shall
     be fixed in the following manner.  The Company shall notify the Trustee in
     writing of the amount of Defaulted Interest proposed to be paid on each
     such Registered Security and the date of the proposed payment, and at the
     same time the Company shall deposit with the Trustee an amount of money
     equal to the aggregate amount proposed to be paid in respect of such
     Defaulted Interest or shall make arrangements satisfactory to the Trustee
     for such deposit prior to the date of the proposed payment, such money when
     deposited to be held in trust for the benefit of the Persons entitled to
     such Defaulted Interest as in this clause provided. Thereupon the Trustee
     shall fix a Special Record Date for the payment of such Defaulted Interest
     which date shall be not more than 15 days and not less than 10 days prior
     to the date of the proposed payment and not less than 10 days after the
     receipt by the Trustee of the notice of the proposed payment.  The Trustee
     shall promptly notify the Company of such Special Record Date and, in the
     name and at the expense of the Company, shall cause notice of the proposed
     payment of such Defaulted Interest and the Special Record Date therefor to
     be mailed, first-class postage prepaid, to the Holders of such Registered
     Securities at their addresses as they appear in the

                                       23
<PAGE>
 
     Security Register, not less than 10 days prior to such Special Record Date.
     Notice of the proposed payment of such Defaulted Interest and the Special
     Record Date therefor having been mailed as aforesaid, such Defaulted
     Interest shall be paid to the Persons in whose names such Registered
     Securities (or their respective Predecessor Securities) are registered at
     the close of business on such Special Record Date and shall no longer be
     payable pursuant to the following clause (2).

          (2) The Company may make payment of any Defaulted Interest on
     Registered Securities in any other lawful manner not inconsistent with the
     requirements of any securities exchange on which such Registered Securities
     may be listed, and upon such notice as may be required by such exchange,
     if, after notice given by the Company to the Trustee of the proposed
     payment pursuant to this clause, such manner of payment shall be deemed
     practicable by the Trustee.

          (c) Subject to the foregoing provisions of this Section, each Debt
Security delivered under this Indenture upon transfer of or in exchange for or
in lieu of any other Debt Security shall carry the rights to interest accrued
and unpaid, and to accrue, which were carried by such other Debt Security.

          Section 3.08. Cancellation.
                        ------------ 

          Unless otherwise specified pursuant to Section 3.01 for Debt
Securities of any series, all Debt Securities surrendered for payment,
redemption, transfer, exchange or credit against any sinking fund shall, if
surrendered to any Person other than the Trustee, be delivered to the Trustee.
All Registered Securities so delivered shall be promptly cancelled by the
Trustee.  The Company may at any time deliver to the Trustee for cancellation
any Debt Securities previously authenticated and delivered hereunder which the
Company may have acquired in any manner whatsoever, and may deliver to the
Trustee (or to any other Person for delivery to the Trustee) for cancellation
any Debt Securities previously authenticated hereunder which the Company has not
issued, and all Debt Securities so delivered shall be promptly cancelled by the
Trustee.  No Debt Securities shall be authenticated in lieu of or in exchange
for any Debt Securities cancelled as provided in this Section, except as
expressly permitted by this Indenture.  All cancelled Debt Securities held by
the Trustee shall be delivered to the Company upon Company Request.  The
acquisition of any Debt Securities by the Company shall not operate as a
redemption or satisfaction of the indebtedness represented thereby unless and
until such Debt Securities are surrendered to the Trustee for cancellation.
Permanent Global Notes shall not be destroyed until exchanged in full for
definitive Debt Securities or until payment thereon is made in full.

          Section 3.09. Computation of Interest.
                        ----------------------- 

          Except as otherwise specified pursuant to Section 3.01 for Debt
Securities of any series, interest on the Debt Securities of each series shall
be computed on the basis of a 360-day year of twelve 30-day months.
 
          Section 3.10. Judgments.
                        --------- 

          The Company agrees, to the fullest extent that it may effectively do
so under applicable law, that (a) if for the purpose of obtaining judgment in
any court it is necessary to convert the sum due in respect of the principal of,
or premium or interest, if any, on the Debt Securities of any series (the
"Required Currency") into a currency in which a judgment will be rendered (the
"Judgment Currency"), the rate of exchange used shall be the rate at which in
accordance with normal banking procedures the

                                       24
<PAGE>
 
Trustee could purchase in the City of New York the Required Currency with the
Judgment Currency on the New York Banking Day (as defined below) preceding that
on which final unappealable judgment is given and (b) its obligations under this
Indenture to make payments in the Required Currency (i) shall not be discharged
or satisfied by any tender, or any recovery pursuant to any judgment (whether or
not entered in accordance with subsection (a)), in any currency other than the
Required Currency, except to the extent that such tender or recovery shall
result in the actual receipt, by the payee, of the full amount of the Required
Currency expressed to be payable in respect of such payments, (ii) shall be
enforceable as an alternative or additional cause of action for the purpose of
recovering in the Required Currency the amount, if any, by which such actual
receipt shall fall short of the full amount of the Required Currency so
expressed to be payable and (iii) shall not be affected by judgment being
obtained for any other sum due under this Indenture.  For purposes of the
foregoing,"New York Banking Day" means any day except a Saturday, Sunday or a
legal holiday in the City of New York or a day on which banking institutions in
the City of New York are authorized or required by law or executive order to
close.

          Section 3.11.  Exchange Upon Default.
                         --------------------- 

          If default is made in the payments referred to in Section 12.01, the
Company hereby undertakes that upon presentation and surrender of a permanent
Global Note to the Trustee (or to any other Person or at any other address as
the Company may designate in writing), on any Business Day on or after the
maturity date thereof the Company will issue and the Trustee will authenticate
and deliver to the bearer of such permanent Global Note duly executed and
authenticated definitive Debt Securities with the same issue date and maturity
date as set out in such permanent Global Note.

                        --------------------------------------- 

          This Indenture, with respect to the Debt Securities of any series (if
all series issued under this Indenture are not to be affected), shall, upon
Company Request, cease to be of further effect (except as to any surviving
rights of registration of transfer or exchange of such Debt Securities herein
expressly provided for and rights to receive payments of principal (and premium,
if any) and interest on such Debt Securities) and the Trustee, at the expense of
the Company, shall execute proper instruments acknowledging satisfaction and
discharge of this Indenture, when

          (1)  either

          (A) all Debt Securities of such series theretofore authenticated and
     delivered (other than (i) Debt Securities of such series which have been
     destroyed, lost or stolen and which have been replaced or paid as provided
     in Section 3.06, and (ii) Debt Securities of such series for whose payment
     money has theretofore been deposited in trust or segregated and held in

     Trustee for cancellation; or

          (B) all Debt Securities of such series not theretofore delivered to

                     the Company,

     and the Company, either complies with any other condition or terms
     specified pursuant to Section 3.01, or if not so specified in the case of
     (i), (ii) or (iii) of this subclause (B), has irrevocably deposited or
     caused to be deposited with the Trustee as trust funds in trust for such
     purpose an amount sufficient to pay and discharge the entire indebtedness
     on such Debt Securities for principal (and premium, if any) and interest to
     the date of such deposit (in the case of Debt Securities which have become
     due and payable) or to the Stated Maturity or Redemption Date, as the case
     may be; provided, however, in the event a petition for relief under the
             --------  -------                                              
     Federal bankruptcy laws, as now or hereafter constituted, or any other
     applicable Federal or state bank  ruptcy, insolvency or other similar law,
     is filed with respect to the Company within 91 days after the deposit and
     the Trustee is required to return the deposited money to the Company, the
     obli  gations of the Company under this Indenture with respect to such Debt
     Securities shall not be deemed terminated or discharged;

          (2) the Company has paid or caused to be paid all other sums payable
     hereunder by the Company;

          (3) the Company has delivered to the Trustee an Officers' Certificate
     and an Opinion of Counsel each stating that all conditions precedent herein
     provided for relating to the satisfaction and discharge of this Indenture
     with respect to such series have been complied with; and

          (4) the Company has delivered to the Trustee an Opinion of Counsel or
     a ruling by the Internal Revenue Service to the effect that Holders of the

Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Company to the Trustee under Section 6.07, the obligations of
the Trustee to any Authenticating Agent under Section 6.14, the obligations of
the Company under Section 12.01, and, if money shall have been deposited with
the Trustee pursuant to subclause (B) of clause (1) of this Section, the

12.04, shall survive.

          Section 4.02. Application of Trust Money.

          Subject to the provisions of the last paragraph of Section 12.04, all
money deposited with the Trustee pursuant to Section 4.01 shall be held in trust
and applied by it, in accordance with the provisions of the Debt Securities and
this Indenture, to the payment, either directly or through any Paying Agent
(including the Company acting as its own Paying Agent) as the Trustee may
determine, to the Persons entitled thereto, of the principal (and premium, if
any) and interest for whose payment such money has been deposited with the
Trustee.

     specifically dealt with or which expressly has been included in this
     Indenture solely for the benefit of Debt Securities of a series other than
     such series), and continuance of such default or breach for a period of 30
     days after there has been given, by registered or certified mail, to the
     Company by the Trustee or to the Company and the Trustee by the Holders of
     at least 30% in principal amount of the Outstanding Debt Securities of such
     series, a written notice specifying such default or breach and requiring it
     to be remedied and stating that such notice is a "Notice of Default"
     hereunder; or

     insolvent, or approving as properly filed a petition seeking
     reorganization, arrangement, adjustment or composition of or in respect of
     the Company under any applicable Federal or State law, or appointing a
     receiver, liquidator, assignee, custodian, trustee, sequestrator (or other
     similar official) of the Company or of any substantial part of its

     in writing of its inability to pay its debts generally as they

                                       27

     become due, or the taking of corporate action by the Company in furtherance
     of any such action; or

     Securities of that series pursuant to Section 3.01.

          Section 5.02. Acceleration of Maturity; Rescission and Annulment.
                        -------------------------------------------------- 

          If an Event of Default with respect to Debt Securities of any series
at the time Outstanding occurs and is continuing, then in every such case the
Trustee or the Holders of not less than 25% in principal amount of the
Outstanding Debt Securities of such series may declare the principal amount (or,
if any Debt Securities of such series are Discount Securities, such portion of
the principal amount of such Discount Securities as may be specified in the
terms of such Discount Securities) of all the Debt Securities of such series to
be due and payable immediately, by a notice in writing to the Company (and to
the Trustee if given by Holders), and upon any such declaration such principal
amount (or specified amount) plus accrued and unpaid interest (and premium, if
payable) shall become immediately due and payable.  Upon payment of such amount,
all obligations of the Company in respect of the payment of principal of the
Debt Securities of such series shall terminate.

          At any time after such a declaration of acceleration with respect to
Debt Securities of any series has been made and before a judgment or decree for
payment of the money due has been obtained by the Trustee as hereinafter in this
Article provided, the Holders of a majority in principal amount of the
Outstanding Debt Securities of such series, by written notice to the Company and
the Trustee, may rescind and annul such declaration and its consequences if

          (1) the Company has paid or deposited with the Trustee a sum
              sufficient to pay

          (A) all overdue installments of interest on all Debt Securities,

          (B) the principal of (and premium, if any, on) any Debt Securities of
              such series which have become due otherwise than by such
              declaration of acceleration and interest thereon at the rate or
              rates prescribed therefor in such Debt Securities,

          (C) to the extent that payment of such interest is lawful, interest
              upon overdue installments of interest on each Debt Security of
              such series at the Overdue Rate, and

          (D) all sums paid or advanced by the Trustee hereunder and the
              reasonable compensation, expenses, disbursements and advances of
              the Trustee, its agents and counsel;

     and

          (2) All Events of Default with respect to Debt Securities of such
     series, other than the nonpayment of the principal of Debt Securities of
     such series which has become due solely by such declaration of
     acceleration, have been cured or waived as provided in Section 5.13.

No such rescission and waiver shall affect any subsequent  default or impair any
right consequent thereon.

by Trustee.
- ---------- 

          The Company covenants that if

          (1) default is made in the payment of any installment of interest on
     any Debt Security when such interest or payment becomes due and payable and
     such default continues for a period of 30 days,

          (2) default is made in the payment of principal of (or premium, if
     any, on) any Debt Security at the Maturity thereof, or

          (3) default is made in the making or satisfaction of any sinking fund
     payment or analogous obligation when the same becomes due pursuant to the
     terms of the Debt Securities of any series,

the Company will, upon demand of the Trustee, pay to it, for the benefit of the
Holders of such Debt Securities, the amount then due and payable on such Debt
Securities for the principal (and premium, if any) and interest, if any, and, to
the extent that payment of such interest shall be legally enforceable, interest
upon the overdue principal (and premium, if any) and upon overdue installments
of interest, at the Overdue Rate; and, in addition thereto, 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.

          If the Company fails to pay such amount forthwith upon such demand,
the Trustee, in its own name and as trustee of an express trust, may institute a
judicial proceeding for the collection of the sums so due and unpaid, and may
prosecute such proceeding to judgment or final decree, and may enforce the same
against the Company or any other obligor upon such Debt Securities and collect
the moneys adjudged or decreed to be payable in the manner provided by law out
of the property of the Company or any other obligor upon such Debt Securities
wherever situated.

          If an Event of Default with respect to Debt Securities of any series
occurs and is continuing, the Trustee may in its discretion proceed to protect
and enforce its rights and the rights of the Holders of Debt Securities of such
series by such appropriate judicial proceedings as the Trustee shall deem most
effectual to protect and enforce any such rights, whether for the specific
enforcement of any covenant or agreement in this Indenture or in aid of the
exercise of any power granted herein, or to enforce any other proper remedy.

          In case of the pendency of any receivership, insolvency, liquidation,
bankruptcy, reorganization, arrangement, adjustment, composition or other
judicial proceedings, or any voluntary or involuntary case under the Federal

          (5) no direction inconsistent with such written request has been given

     principal amount of the Outstanding Debt Securities of such series;

it being understood and intended that no one or more of such Holders shall have
any right in any manner whatever by virtue of, or by availing of, any provision
of this Indenture to affect, disturb or prejudice the rights of any other such
Holders or of the Holders of Outstanding Debt Securities of any other series, or
to obtain or to seek to obtain priority or preference over any other of such
Holders or to enforce any right under this Indenture, except in the manner

Section 3.07) interest on such Debt Security on the respective Stated Maturity
or Maturities expressed in such Debt Security (or, in the case of redemption, on

          Except as otherwise expressly provided elsewhere in this Indenture, no
right or remedy herein conferred upon or reserved to the Trustee or to the
Holders is intended to be exclusive of any other right or remedy, and every
right and remedy shall, to the extent permitted by law, be cumulative and in
addition to every other right and remedy given hereunder or now or hereafter
existing at law or in equity or otherwise.  The assertion or employment of any
right or remedy hereunder, or otherwise, shall not prevent the concurrent
assertion or employment of any other appropriate right or remedy.

          Section 5.11. Delay or Omission Not Waiver.
                        ---------------------------- 

          No delay or omission of the Trustee or of any Holder to exercise any
right or remedy accruing upon any Event of Default shall impair any such right
or remedy or constitute a waiver of any such Event of Default or any
acquiescence therein.  Every right and remedy given by this Indenture or by law
to the Trustee or to the Holders may be exercised from time to time, and as
often as may be deemed expedient, by the Trustee or by the Holders, as the case

Securities of any series shall have the right to direct the time, method and
place of conducting any proceeding for any remedy available to the Trustee or
exercising any trust or power conferred on the Trustee with respect to the Debt
Securities of such series, provided, that

          (1) such direction shall not be in conflict with any rule of law or
     with this Indenture;

          (2) subject to the provisions of Section 6.01, the Trustee shall have
     the right to decline to follow any such direction if the Trustee in good
     faith shall, by a Responsible Officer or Responsible Officers of the
     Trustee, determine that the proceeding so directed would be unjustly
     prejudicial to the Holders of Debt Securities of such series not joining in
     any such direction; and

          (3) the Trustee may take any other action deemed proper by the Trustee
     which is not inconsistent with such direction.

of the Outstanding Debt Securities of any series may on behalf of the Holders of
all the Debt Securities of any such series waive any past default hereunder with
respect to such series and its consequences, except a default

          (1) in the payment of the principal of (or premium, if any) or
     interest on any Debt Security of such series, or in the payment of any
     sinking fund installment or analogous obligation with respect to the Debt
     Securities of such series, or

                                       32
<PAGE>
 
          (2) in respect of a covenant or provision hereof which pursuant to
     Article Eleven cannot be modified or amended without the consent of the
     Holder of each Outstanding Debt Security of such series affected.

          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 the Debt Securities of such series under this Indenture, but no such
waiver shall extend to any subsequent or other default or impair any right
consequent thereon.

          Section 5.14. Undertaking for Costs.
                        --------------------- 

          All parties to this Indenture agree, and each Holder of any Debt
Security by his accept  ance thereof shall be deemed to have agreed, that any
court may in its discretion require, 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, suffered or omitted by it as Trustee, the filing by any party
litigant in such suit other than the Trustee of an undertaking to pay the costs
of such suit, and that such court may in its discretion assess reasonable costs,
including reasonable attorneys' fees, against any party litigant in such suit,
having due regard to the merits and good faith of the claims or defenses made by
such party litigant, but the provisions of this Section shall not apply to any
suit instituted by the Trustee, to any suit instituted by any Holder or group of
Holders holding in the aggregate more than 10% in principal amount of the
Outstanding Debt Securities of any series, or to any suit instituted by any
Holder of a Debt Security for the enforcement of the payment of the principal of
(or premium, if any) or interest on such Debt Security on or after the
respective Stated Maturity or Maturities expressed in such Debt Security (or, in
the case of redemption, on or after the Redemption Date).

          Section 5.15. Waiver of Stay or Extension Laws.
                        -------------------------------- 

          The Company covenants (to the extent that it may lawfully do so) that
it will not at any time insist upon, or plead, or in any manner whatsoever claim
or take the benefit or advantage of, any stay or extension law wherever enacted,
now or at any time hereafter in force, which 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 will not hinder, delay or impede the execution of any
power herein granted to the Trustee, but will suffer and permit the execution of
every such power as though no such law had been enacted.

          (a) Except during the continuance of an Event of Default with respect
to the Debt Securities of any series,

          (1) the Trustee undertakes to perform such duties and only such duties
     as are specifically set forth in this Indenture, and no implied covenants
     or obligations shall be read into this Indenture against the Trustee; and

                                       33
<PAGE>
 
          (2) in the absence of bad faith on its part, the Trustee may
     conclusively rely, as to the truth of the statements and the correctness of
     the opinions expressed therein, upon certificates or opinions furnished to
     the Trustee and conforming to the requirements of this Indenture; but in
     the case of any such certificates or opinions which by any provisions
     hereof are specifically required to be furnished to the Trustee, the
     Trustee shall be under a duty to examine the same to determine whether or
     not they conform to the requirements of this Indenture.

          (b) In case an Event of Default with respect to Debt Securities of any
series has occurred and is continuing, the Trustee shall, with respect to the
Debt Securities of such series, exercise such of the rights and powers vested in
it by this Indenture, and 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.

          (c) No provision of this Indenture shall be construed to relieve the
Trustee from liability for its own negligent action, its own negligent failure
to act, or its own willful misconduct, except that

          (1) this subsection shall not be construed to limit the effect of
     subsection (a) of this Section;

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

          (3) the Trustee shall not be liable with respect to any action taken,
     suffered or omitted to be taken by it with respect to Debt Securities of
     any series in good faith in accordance with the direction of the Holders of
     a majority in principal amount of the Outstanding Debt Securities of such
     series relating to the time, method and place of conducting any proceeding
     for any remedy available to the Trustee, or exercising any trust or power
     conferred upon the Trustee, under this Indenture; and

          (4) the Trustee shall not be required to expend or risk its own funds
     or otherwise incur any financial liability in the performance of any of its
     duties hereunder, or in the exercise of any of its rights or powers, if it
     shall have reasonable grounds for believing that repayment of such funds or
     adequate indemnity against such risk or liability is not reasonably assured
     to it.

          (d) Whether or not therein expressly so provided, every provision of
this Indenture relating to the conduct or affecting the liability of or
affording protection to the Trustee shall be subject to the provisions of this
Section.

Holders of Debt Securities of such series of such default hereunder known to the
Trustee, unless such default shall have been cured or waived; provided, however,
                                                              --------  -------

Responsible Officers of the Trustee in good faith determine that the withholding
of such notice is in the interest of the Holders of Debt Securities of such
series; and provided, further, that in the case of any default of the character
            --------  -------                                                  
specified in Section 5.01(4) with respect to Debt Securities of such series no
such notice to Holders shall be given until at least 30 days after the

rely upon an Officers' Certificate;

make such further inquiry or investigation, it shall

                                       35
<PAGE>
 
be entitled to examine the books, records and premises of the Company,
personally or by agent or attorney; and

          (g) the Trustee may execute any of the trusts or powers hereunder or
perform any duties hereunder either directly or by or through agents or
attorneys and the Trustee shall not be responsible for any misconduct or
negligence on the part of any agent or attorney appointed with due care by it

Securities.

          The recitals contained herein and in the Debt Securities, except the
Trustee's certificates of authentication, shall be taken as the statements of
the Company, and the Trustee assumes no responsibility for their correctness.
The Trustee makes no representations as to the validity or sufficiency of this
Indenture or of the Debt Securities of any series.  The Trustee shall not be
accountable for the use or application by the Company of any Debt Securities or
the proceeds thereof.

          The Trustee, any Paying Agent, the Security Registrar or any other

owner or pledgee of Debt Securities with the same rights it would have if it
were not the Trustee, Paying Agent, Security Agent or such other agent, and,
subject to Sections 6.08 and 6.13, may otherwise deal with the Company with the
same rights it would have if it were not Trustee, Paying Agent, Security
Registrar or such other agent.

          Section 6.06. Money Held in Trust.
                        ------------------- 

          Money in any currency held by the Trustee or any Paying Agent in trust

for interest on any money received by it hereunder except as otherwise agreed
with the Company.

          Section 6.07. Compensation and Reimbursement.
                        ------------------------------ 

          The Company agrees:

          (1) to pay to the Trustee from time to time reasonable compensation
     for all services rendered by it hereunder (which compensation shall not be
     limited by any provision of law in regard to the compensation of a trustee
     of an express trust);

          (2) except as otherwise expressly provided herein, to reimburse the
     trustee upon its request for all reasonable expenses, disbursements and
     advances incurred or made by the Trustee in accordance with any provision
     of this Indenture (including the reasonable compensation and the expenses
     and disbursements of its agents and counsel), except any such expense,
     disbursement or advance as may be attributable to its negligence or bad
     faith; and

          (3) to indemnify the Trustee for, and to hold it harmless against, any
     loss, liability or expense incurred without negligence or bad faith on its
     part, arising out of or in connection with the acceptance or administration
     of this trust or performance of its duties hereunder,

                                       36

          As security for the performance of the obligations of the Company
under this Section, the Trustee shall have a claim prior to the Debt Securities
upon all property and funds held or collected by the Trustee as such, except
funds held in trust for the payment of amounts due on the Debt Securities.

          The obligations of the Company under this Section 6.07 to compensate
and indemnify the Trustee for expenses, disbursements and advances shall
constitute additional indebtedness under this Indenture and shall survive the
satisfaction and discharge of this Indenture.

          Section 6.08. Disqualification; Conflicting Interests.
                        --------------------------------------- 

          (a) If the Trustee has or shall acquire any conflicting interest, as
defined in this Section with respect to the Debt Securities of any series, then,
within 90 days after ascertaining that it has such conflicting interest, and if
the default (as hereinafter defined) to which such conflicting interest relates
has not been cured or duly waived or otherwise eliminated before the end of such
90-day period, the Trustee shall either eliminate such conflicting interest or,
except as otherwise provided below, resign with respect to the Debt Securities
of such series, and the Company shall take prompt steps to have a successor
appointed, in the manner and with the effect hereinafter specified in this
Article.

          (b) In the event that the Trustee shall fail to comply with the
provisions of subsection (a) of this Section with respect to the Debt Securities

of such failure.

          Notice given pursuant to this Section 6.08(b) shall be transmitted by

     address appear in the information preserved at the time by the Trustee in
     accordance with Section 7.02(a) of this Indenture.

          (c) For the purposes of this Section, the Trustee shall be deemed to
have a conflicting interest with respect to the Debt Securities of any series,
if there shall exist an Event of Default (as such term is defined herein, but
exclusive of any period of grace or requirement of notice) with respect to such
Debt Securities and

          (1) the Trustee is trustee under this Indenture with respect to the
     Outstanding Debt Securities of any series other than that series or is
     trustee under another indenture under which any other securities, or
     certificates of interest or participation in any other securities, of the
     Company are outstanding, unless such other indenture is a collateral trust
     indenture under which the only collateral consists of Debt Securities
     issued under this Indenture, provided that there shall be excluded from the
     operation of this paragraph of this Indenture with respect to the Debt
     Securities of any series other than that series and any other indenture or
     indentures under which other securities, or certificates of interest or

               (i) this Indenture and such other indenture or indentures (and
          all series of securities issuable thereunder) are wholly unsecured and
          rank equally and such other indenture or indentures are hereafter
          qualified under the Trust Indenture Act, unless the Commission shall
          have found and declared by order pursuant to Section 305(b) or Section
          307(c) of the Trust Indenture Act that differences exist between the
          provisions of this Indenture with respect to the Debt Securities of
          such series and one or more other series or the provisions of such
          other indenture or indentures which are so likely to involve a
          material conflict of interest as to make it necessary, in the public
          interest or for the protection of investors to disqualify the Trustee
          from acting as such under this Indenture with respect to the Debt
          Securities of such series and such other series or under such other
          indenture or indentures, or

              (ii)  the Company shall have sustained the burden of proving, on
          application to the Commission and after opportunity for hearing
          thereon, that trusteeship under this Indenture with respect to the
          Debt Securities of such series and such other series or such other
          indenture or indentures is not so likely to involve a material
          conflict of interest as to make it necessary in the public interest or
          for the protection of investors to disqualify the Trustee from acting
          as such under this Indenture with respect to the Debt Securities of
          such series and such other series or under such other indenture or
          indentures;

     that (i) one individual may be a director or an executive officer, or both,
     of the Trustee and a director or an executive officer, or both, of the
     Company but may not be at the same time an executive officer of both the
     Trustee and the Company; (ii) if and so long as the number of directors of
     the Trustee in office is more than nine, one additional individual may be a
     director or an executive officer, or both, of the Trustee and a director of
     the Company; and (iii) the Trustee may be designated by the Company or by
     any underwriter for the Company to act in the capacity of transfer agent,
     registrar, custodian, paying agent, fiscal agent, escrow agent, or
     depositary or in any other similar capacity, or, subject to the provisions
     of paragraph (c) of this subsection, to act as trustee, whether under an
     indenture or otherwise;

          (5) 10% or more of the voting securities of the Trustee is
     beneficially owned either by the Company or by any director, partner or

<PAGE>
 
     the Debt Securities issued under this Indenture and securities issued under

     more of any class of security of an underwriter for the Company;

          (7) the Trustee is the beneficial owner of or holds as collateral
     security for an obligation which is in default, 5% or more of the voting

     similar capacity, an aggregate of 25% or more of the voting securities, or
     of any class of security, of any person, the beneficial ownership of a
     specified percentage of which would have constituted a conflicting interest

     securities of which the Trustee acquired ownership through becoming
     executor, administrator or testamentary trustee of an estate which included
     them, the provisions of the preceding sentence shall not apply, for a
     period of not more than two years from the date of such acquisition, to the
     extent that such securities included in such estate do not exceed 25% of
     such voting securities or 25% of any such class of security.  Promptly
     after the dates of any such Event of Default and annually in each
     succeeding year that such Event of Default continues, the Trustee shall
     make a check of its holdings of such securities in any of the above-
     mentioned capacities as of such dates.  If the Company fails to make
     payment in full of the principal of (or premium, if any) or interest on any
     of the Debt Securities when and as the same becomes due and payable, and
     such failure continues for 30 days thereafter, the Trustee shall make a
     prompt check of its holdings of such securities in any of the above-
     mentioned capacities as of the date of the expiration of such 30-day
     period, and after such date, notwithstanding the foregoing provisions of
     this paragraph, all such securities so held by the Trustee, with sole or
     joint control over such securities vested in it, shall be considered as
     though beneficially owned by the Trustee for the purposes of paragraphs
     (6), (7) and (8) of this subsection; or

          (10) except under the circumstances described in paragraphs (1), (3),
     (4), (5) or (6) of Section 6.13(b) of this Indenture, the Trustee shall be
     or shall become a creditor of the Company.

          For the purposes of paragraph (1) of this subsection, the term "series
of securities" or "series" means a series, class or group of securities issuable
under an indenture pursuant to whose terms holders of one such series may vote
to direct the Trustee, or otherwise take action pursuant to a vote of such
holders, separately from holders of another series; provided, that "series of
                                                    --------                 
securities" or "series" shall not include any series of securities issuable
under an indenture if all such series rank equally and are wholly unsecured.

          The specification of percentages in paragraphs (5) to (9), inclusive,
of this subsection shall not be construed as indicating that the ownership of
such percentages of the securities of a person is or

                                       39

include any note or other evidence of indebtedness issued to evidence an
obligation to repay moneys lent to a person by one or more banks, trust
companies or banking firms, or any certificate of interest or participation in
any such note or evidence of indebtedness; (ii) an obligation shall be deemed to
be "in default" when a default in payment of principal shall have continued for
30 days or more and shall not have been cured; and (iii) the Trustee shall not
be deemed to be the owner or holder of (A) any security which it holds as
collateral security, as trustee or otherwise, for an obligation which is not in
default as defined in clause (ii) above, or (B) any security which it holds as
collateral security under this Indenture, irrespective of any default hereunder,
or (C) any security which it holds as agent for collection, or as custodian,
escrow agent or depositary, or in any similar representative capacity.

          (e) The percentages of voting securities and other securities

     shares if relating to capital shares, and the number of units if relating
     to any other kind of security.

          (4) The term "outstanding" means issued and not held by or for the
     account of the issuer.  The following securities shall not be deemed
     outstanding within the meaning of this definition:

          by such other class of securities is not in default as to principal or
          interest or otherwise;

               (iii)  securities pledged by the issuer thereof as security for

     outstanding if any person other than the issuer is entitled to exercise the
     voting rights thereof.

          (5) A security shall be deemed to be of the same class as another
     security if both securities confer upon the holder or holders thereof
     substantially the same rights and privileges; provided, however, that, in
                                                   --------  -------          
     the case of secured evidences of indebtedness, all of which are issued
     under a single indenture, differences in the interest rates or maturity
     dates of various series thereof shall not be deemed sufficient to
     constitute such series different classes; and provided, further, that, in
                                                   --------  -------          
     the case of unsecured evidences of indebtedness, differences in the
     interest rates or maturity dates thereof shall not be deemed sufficient to
     constitute them securities of different classes, whether or not they are
     issued under a single indenture.

                                       41

or interest on any Debt Security of any series, or in the payment of any sinking
or purchase fund installment, the Trustee shall not be required to resign as

proving, on application to the Commission and after opportunity for hearing
thereon, that:

          (1) the Event of Default may be cured or waived during a reasonable
     period and under the procedures described in such application; and

          (2) a stay of the Trustee's duty to resign will not be inconsistent
     with the interests of Holders of the Debt Securities.

The filing of such an application shall automatically stay the performance of
the duty to resign until the Commission orders otherwise.

          Section 6.10. Resignation and Removal; Appointment of Successor.
                        ------------------------------------------------- 

          (a) No resignation or removal of the Trustee and no appointment of a
successor Trustee pursuant to this Article shall become effective until the
acceptance of appointment by the successor Trustee under Section 6.11.

          (b) The Trustee may resign at any time with respect to the Debt
Securities of one or more series by giving written notice thereof to the
Company.  If an instrument of acceptance by a successor Trustee shall not have
been delivered to the Trustee within 30 days after the giving of such notice of
resignation, the resigning Trustee may petition any court of competent
jurisdiction for the appointment of a successor Trustee with respect to the Debt
Securities of such series.

          (c) The Trustee may be removed at any time with respect to the Debt
Securities of any series and a successor Trustee appointed by Act of the Holders
of a majority in principal amount of the Outstanding Debt Securities of such
series, delivered to the Trustee and to the Company.

          (d)  If at any time:

          (1) the Trustee shall fail to comply with Section 6.08(a) with respect
     to the Debt Securities of any series after written request therefor by the
     Company or by any Holder who has been a bona fide Holder of a Debt Security
     of such series for at least six months, or

                                       42
<PAGE>
 
          (2) the Trustee shall cease to be eligible under Section 6.09 with
     respect to the Debt Securities of any series and shall fail to resign after
     written request therefor by the Company or by any such Holder, or

          (3) the Trustee shall become incapable of acting or shall be adjudged
     a bankrupt or insolvent or a receiver of the Trustee or of its property
     shall be appointed or any public officer shall take charge or control of
     the Trustee or of its property or affairs for the purpose of
     rehabilitation, conservation or liquidation,

then, in any such case, (i) the Company by a Board Resolution may remove the
Trustee with respect to all Debt Securities, or (ii) subject to Section 5.14,
any Holder who has been a bona fide Holder of a Debt Security of any series for
at least six months may, on behalf of himself and all others similarly situated,
petition any court of competent jurisdiction for the removal of the Trustee and
the appointment of a successor Trustee for the Debt Securities of such series.

          (e) If the Trustee shall resign, be removed or become incapable of
acting, or if a vacancy shall occur in the office of Trustee for any cause, with
respect to the Debt Securities of one or more series, the Company, by a Board
Resolution, shall promptly appoint a successor Trustee or Trustees with respect
to the Debt Securities of that or those series (it being understood that any
such successor Trustee may be appointed with respect to the Debt Securities of
one or more or all of such series and that at any time there shall be only one
Trustee with respect to the Debt Securities of any particular series) and shall
comply with the applicable requirements of Section 6.11.  If, within one year
after such resignation, removal or incapability, or the occurrence of such
vacancy, a successor Trustee with respect to the Debt Securities of any series
shall be appointed by Act of the Holders of a majority in principal amount of
the Outstanding Debt Securities of such series delivered to the Company and the
retiring Trustee, the successor Trustee so appointed shall, forthwith upon its
acceptance of such appointment, become the successor Trustee with respect to the
Debt Securities of such series and to that extent supersede the successor
Trustee appointed by the Company.  If no successor Trustee with respect to the
Debt Securities of any series shall have been so appointed by the Company or the
Holders of such series and accepted appointment in the manner hereinafter
provided, any Holder who has been a bona fide Holder of a Debt Security of such
series for at least six months may, subject to Section 5.14, on behalf of
himself and all others similarly situated, petition any court of competent
jurisdiction for the appointment of a successor Trustee with respect to the Debt
Securities of such series.

          (f) The Company shall give notice of each resignation and each removal
of the Trustee with respect to the Debt Securities of any series and each
appointment of a successor Trustee with respect to the Debt Securities of any
series in the manner and to the extent provided in Section 1.05 to the Holders
of Debt Securities of such series.  Each notice shall include the name of the
successor Trustee with respect to the Debt Securities of such series and the

                        -------------------------------------- 

          (a) In the case of an appointment hereunder of a successor Trustee
with respect to all Debt Securities, each such successor Trustee so appointed
shall execute, acknowledge and deliver to the Company and to the retiring
Trustee an instrument accepting such appointment, and thereupon the resignation
or removal of the retiring Trustee shall become effective and such successor
Trustee, without any further act, deed or conveyance, shall become vested with
all the rights, powers, trusts and duties of the retiring Trustee, but, on
request of the Company or the successor Trustee, such retiring Trustee shall,
upon payment of its charges, execute and deliver an instrument transferring to
such successor

duly assign, transfer and deliver to such successor Trustee all property and
money held by such retiring Trustee hereunder, subject nevertheless to its
claim, if any, provided for in Section 6.07.

          (b) In case of the appointment hereunder of a successor Trustee with
respect to the Debt Securities of one or more (but not all) series, the Company,
the retiring Trustee and each successor Trustee with respect to the Debt
Securities of one or more series shall execute and deliver an indenture
supplemental hereto wherein each successor Trustee shall accept such appointment
and which (1) shall contain such provisions as shall be necessary or desirable
to transfer and confirm to, and to vest in, each successor Trustee all the
rights, powers, trusts and duties of the retiring Trustee with respect to the
Debt Securities of that or those series to which the appointment of such
successor Trustee relates, (2) if the retiring Trustee is not retiring with
respect to all Debt Securities, shall contain such provisions as shall be deemed
necessary or desirable to confirm that all the rights, powers, trusts and duties
of the retiring Trustee with respect to the Debt Securities of that or those
series as to which the retiring Trustee is not retiring shall continue to be
vested in the retiring Trustee, and (3) shall add to or change any of the
provisions of this Indenture as shall be necessary to provide for or facilitate
the administration of the trusts hereunder by more than one Trustee, it being
understood that nothing herein or in any such supplemental indenture shall
constitute such Trustees co-trustees of the same trust and that each such
Trustee shall be trustee of a trust or trusts hereunder separate and apart from
any other trust or trusts hereunder administered by any other such Trustee; and
upon the execution and delivery of any such supplemental indenture the
resignation or removal of the retiring Trustee shall become effective to the
extent provided therein and each such successor Trustee, without any further
act, deed or conveyance, shall become vested with all the rights, powers, trusts
and duties of the retiring Trustee with respect to the Debt Securities of that
or those series to which the appointment of such successor Trustee relates, but,
on request of the Company or any successor Trustee, such retiring Trustee shall
duly assign, transfer and deliver to such successor Trustee all property and
money held by such retiring Trustee hereunder with respect to the Debt
Securities of that or those series to which the appointment of such successor
Trustee relates.

          (c) Upon request of any such successor Trustee, the Company shall
execute any and all instruments for more fully and certainly vesting in and
confirming to such successor Trustee all such rights, powers and trusts referred
to in paragraph (a) or (b) of this Section, as the case may be.

          (d) No successor Trustee shall accept its appointment unless at the
time of such acceptance such successor Trustee shall be qualified and eligible
under this Article.

Business.
- -------- 

          Any corporation into which the Trustee may be merged or converted or
with which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to all or substantially all of the corporate trust
business of the Trustee, shall be the successor of the Trustee hereunder,
provided that such corporation shall be otherwise qualified and eligible under
this Article, without the execution or filing of any paper or any further act on
the part of any of the parties hereto.  In case any Debt Securities shall have
been authenticated, but not delivered, by the Trustee then in office, any
successor by merger, conversion or consolidation to such authenticating Trustee
may adopt such authentication and deliver the Debt Securities so authenticated
with the same effect as if such successor Trustee had itself authenticated such
Debt Securities.  In case any Debt Securities shall not have been authenticated
by such predecessor Trustee, any such successor Trustee may authenticate and
deliver such Debt Securities, in either its own name or

                                       44

Indenture provides for the certificate of authentication of the Trustee.

be or shall become a creditor, directly or indirectly, secured or unsecured, of
the Company within three months prior to a default, as defined in subsection (c)
of this Section, or subsequent to such default, then, unless and until such
default shall be cured, the Trustee shall set apart and hold in a special
account for the benefit of the Trustee individually, the Holders of the Debt
Securities and the holders of other indenture securities (as defined in
subsection (c) of this Section):

          (1)  an amount equal to any and all reductions in the amount due and
     owing upon any claim as such creditor in respect of principal or interest,
     effected after the beginning of such three-month period and valid as
     against the Company and its other creditors, except any such reduction
     resulting from the receipt or disposition of any property described in
     paragraph (2) of this subsection, or from the exercise of any right of set-
     off which the Trustee could have exercised if a voluntary or involuntary
     case had been commenced in respect of the Company under the Federal
     bankruptcy laws, as now or hereafter constituted, or any other applicable
     Federal or State bankruptcy, insolvency or other similar law upon the date
     of such default; and

          (2)  all property received by the Trustee in respect of any claim as
     such creditor, either as security therefor, or in satisfaction or
     composition thereof, or otherwise, after the beginning of such three-month
     period, or an amount equal to the proceeds of any such property, if
     disposed of, subject, however, to the rights, if any, of the Company and
                  -------  -------                                           
     its other creditors in such property or such proceeds.

Nothing herein contained, however, shall affect the right of the Trustee:

          (A)  to retain for its own account (i) payments made on account of any
     such claim by any Person (other than the Company) who is liable thereon,
     and (ii) the proceeds of the bona fide sale of any such claim by the
     Trustee to a third Person, and (iii) distributions made in cash, securities
     or other property in respect of claims filed against the Company in
     bankruptcy or receivership or in proceedings or reorganization pursuant to
     the Federal bankruptcy laws, as now or hereafter constituted, or any other
     applicable Federal or State bankruptcy, insolvency or other similar law;

          (B)  to realize, for its own account, upon any property held by it as
     security for any such claim, if such property was so held prior to the
     beginning of such three-month period;

          (C)  to realize, for its own account, but only to the extent of the
     claim hereinafter mentioned, upon any property held by it as security for
     any such claim, if such claim was created after the beginning of such
     three-month period and such property was received as security therefor
     simultaneously with the creation thereof, and if the Trustee shall sustain
     the burden of proving that at the time such property was so received the
     Trustee had no reasonable cause to believe that a default, as defined in
     subsection (c) of this Section, would occur within three months, or

                                       45
<PAGE>
 
          (D)  to receive payment on any claim referred to in paragraph (B) or
     (C) against the release of any property held as security for such claim as
     provided in paragraph (B) or (C), as the case may be, to the extent of the
     fair value of such property.

          For the purposes of paragraphs (B), (C) and (D), property substituted
after the beginning of such three-month period for property held as security at
the time of such substitution shall, to the extent of the fair value of the
property released, have the same status as the property released, and, to the
extent that any claim referred to in any of such paragraphs is created in
renewal of or in substitution for or for the purpose of repaying or refunding
any pre-existing claim of the Trustee as such creditor, such claim shall have
the same status as such pre-existing claim.

          If the Trustee shall be required to account, the funds and property
held in such special account and the proceeds thereof shall be apportioned among
the Trustee, the Holders and the holders of other indenture securities in such
manner that the Trustee, the Holders and the holders of other indenture
securities realize, as a result of payments from such special account and
payments of dividends on claims filed against the Company in bankruptcy or
receivership or in proceedings for reorganization pursuant to the Federal
bankruptcy laws, as now or hereafter constituted or any other applicable Federal
or State bankruptcy, insolvency or other similar law, the same percentage of
their respective claims, figured before crediting to the claim of the Trustee
anything on account of the receipt by it from the Company of the funds and
property in such special account and before crediting to the respective claims
of the Trustee and the Holders and the holders of other indenture securities
dividends on claims filed against the Company in bankruptcy or receivership or
in proceedings for reorganization pursuant to the Federal bankruptcy laws, as
now or hereafter constituted, or any other applicable Federal or State
bankruptcy, insolvency or other similar law, but after crediting thereon
receipts on account of the indebtedness represented by their respective claims
from all sources other than from such dividends and from the funds and property
so held in such special account.  As used in this paragraph, with respect to any
claim, the term "dividends" shall include any distribution with respect to such
claim, in bankruptcy or receivership or proceedings for reorganization pursuant
to the Federal bankruptcy laws, as now or hereafter constituted, or any other
applicable Federal or State bankruptcy, insolvency or other similar law, whether
such distribution is made in cash, securities, or other property, but shall not
include any such distribution with respect to the secured portion, if any, of
such claim.  The court in which such bankruptcy, receivership or proceedings for
reorganization is pending shall have jurisdiction (i) to apportion among the
Trustee and the Holders and the holders of other indenture securities, in
accordance with the provisions of this paragraph, the funds and property held in
such special account and proceeds thereof, or (ii) in lieu of such
apportionment, in whole or in part, to give to the provisions of this paragraph
due consideration in determining the fairness of the distributions to be made to
the Trustee and the Holders and the holders of other indenture securities with
respect to their respective claims, in which event it shall not be necessary to
liquidate or to appraise the value of any securities or other property held in
such special account or as security for any such claim, or to make a specific
allocation of such distributions as between the secured and unsecured portions
of such claim, or otherwise to apply the provisions of this paragraph as a
mathematical formula.

          Any Trustee which has resigned or been removed after the beginning of
such three-month period shall be subject to the provisions of this subsection as
though such resignation or removal had not occurred.  If any Trustee has
resigned or been removed prior to the beginning of such three-month period, it
shall be subject to the provisions of this subsection if and only if the
following conditions exist:

                                       46
<PAGE>
 
          (i)  the receipt of property or reduction of claim, which would have
     given rise to the obligation to account, if such Trustee had continued as
     Trustee, occurred after the beginning of such three-month period; and

          (ii)  such receipt of property or reduction of claim occurred within
     three months after such resignation or removal.

          (b) There shall be excluded from the operation of subsection (a) of
this Section a creditor relationship arising from:

          (1)  the ownership or acquisition of securities issued under any
     indenture, or any security or securities having a maturity of one year or
     more at the time of acquisition by the Trustee;

          (2)  advances authorized by a receivership or bankruptcy court of
     competent jurisdiction or by this Indenture, for the purpose of preserving
     any property which shall at any time be subject to the Lien of this
     Indenture or of discharging tax liens or other prior liens or encumbrances
     thereon, if notice of such advances and of the circumstances surrounding
     the making thereof is given to the Holders at the time and in the manner
     provided in this Indenture;

          (3)  disbursements made in the ordinary course of business in the
     capacity of trustee under an indenture, transfer agent, registrar,
     custodian, paying agent, fiscal agent or depositary, or other similar
     capacity;

          (4)  an indebtedness created as a result of services rendered or
     premises rented, or an indebtedness created as a result of goods or
     securities sold in a cash transaction as defined in subsection (c) of this
     Section;

          (5)  the ownership of stock or of other securities of a corporation
     organized under the provisions of Section 25(a) of the Federal Reserve Act,
     as amended, which is directly or indirectly a creditor of the Company; and

          (6)  The acquisition, ownership, acceptance or negotiation of any
     drafts, bills of exchange, acceptances or obligations which fall within the
     classification of self-liquidating paper as defined in subsection (c) of
     this Section.

          (c)  for the purposes of this Section only:

          (1)  The term "default" means any failure to make payment in full of
     the principal of or interest on any of the Debt Securities or upon the
     other indenture securities when and as such principal or interest becomes
     due and payable.

          (2)  The term "other indenture securities" means securities upon which
     the Company is an obligor outstanding under any other indenture (i) under
     which the Trustee is also trustee, (ii) which contains provisions
     substantially similar to the provisions of this Section, and (iii) under
     which a default exists at the time of the apportionment of the funds and
     property held in such special account.

                                       47
<PAGE>
 
          (3)  The term "cash transaction" means any transaction in which full
     payment for goods or securities sold is made within seven days after
     delivery of the goods or securities in currency or in checks or other
     orders drawn upon banks and payable upon demand.

          (4)  The term "self-liquidating paper" means any draft, bill of
     exchange, acceptance or obligation which is made, drawn, negotiated or
     incurred by the Company for the purpose of financing the purchase,
     processing, manufacturing, shipment, storage or sale of goods, wares or
     merchandise and which is secured by documents evidencing title to,
     possession of, or a lien upon, the goods, wares or merchandise or the
     receivables or proceeds arising from the sale of the goods, wares or
     merchandise previously constituting the security, provided the security is
     received by the Trustee simultaneously with the creation of the creditor
     relationship with the Company arising from the making, drawing, negotiating
     or incurring of the draft, bill of exchange, acceptance or obligation.

          (5)  The term "Company" means any obligor upon the Debt Securities.

          Section 6.14. Appointment of Authenticating Agent.
                        ----------------------------------- 

          As long as any Debt Securities of a series remain Outstanding, upon a
Company Request, there shall be an authenticating agent (the "Authenticating
Agent") appointed, for such period as the Company shall elect, by the Trustee
for such series of Debt Securities to act as its agent on its behalf and subject
to its direction in connection with the authentication and delivery of each
series of Debt Securities for which it is serving as Trustee.  Debt Securities
of each such series authenticated by such Authenticating Agent shall be entitled
to the benefits of this Indenture and shall be valid and obligatory for all
purposes as if authenticated by such Trustee.  Wherever reference is made in
this Indenture to the authentication and delivery of Debt Securities of any
series by the Trustee for such series or to the Trustee's Certificate of
Authentication, such reference shall be deemed to include authentication and
delivery on behalf of the Trustee for such series by an Authenticating Agent for
such series and a Certificate of Authentication executed on behalf of such
Trustee by such Authenticating Agent.  Such Authenticating Agent shall at all
times be a corporation organized and doing business under the laws of the United
States of America or of any State, authorized under such laws to exercise
corporate trust powers, having a combined capital and surplus of at least
$10,000,000 and subject to supervision or examination by Federal or State
authority.  If such Authenticating Agent publishes reports of condition at least
annually, pursuant to law or to the requirements of said supervising or
examining authority, then for purposes of this Section, the combined capital and
surplus of such Authenticating Agent shall be deemed to be its combined capital
and surplus as set forth in its most recent report of condition so published.
If at any time an Authenticating Agent shall cease to be eligible in accordance
with the provisions of this Section, such Authenticating Agent shall resign
immediately in the manner and with the effect specified in this Section.

          Any corporation into which any Authenticating Agent may be merged or
converted, or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which any Authenticating Agent
shall be a party, or any corporation succeeding to the corporate agency business
of any Authenticating Agent, shall continue to be the Authenticating Agent with
respect to all series of Debt Securities for which it served as Authenticating
Agent without the execution or filing of any paper or any further act on the
part of the Trustee for such series or such Authenticating Agent.  Any
Authenticating Agent may at any time, and if it shall cease to be eligible
shall, resign by giving written notice of resignation to the applicable Trustee
and to the Company.

                                       48
<PAGE>
 
          Upon receiving such a notice of resignation or upon such a
termination, or in case at any time any Authenticating Agent shall cease to be
eligible in accordance with the provisions of this Section 6.14 with respect to
one or more or all series of Debt Securities, the Trustee for such series shall
upon Company Request appoint a successor Authenticating Agent, and the Company
shall provide notice of such appointment to all Holders of Debt Securities of
such series in the manner and to the extent provided in Section 1.05.  Any
successor Authenticating Agent upon acceptance of its appointment hereunder
shall become vested with all rights, powers, duties and responsibilities of its
predecessor hereunder, with like effect as if originally named as Authenticating
Agent herein.  The Company agrees to pay to the Authenticating Agent for such
series from time to time reasonable compensation for its services.  The
Authenticating Agent for the Debt Securities of any series shall have no
responsibility or liability for any action taken by it as such at the direction
of the Trustee for such series.

          If an appointment with respect to one or more series is made pursuant
to this Section, the Debt Securities of such series may have endorsed thereon,
in addition to the Trustee's certificate of authentication, an alternative
certificate of authentication in the following form:

          This is one of the series of Debt Securities issued under the within
mentioned Indenture.

               HOLDERS' LISTS AND REPORTS BY TRUSTEE AND COMPANY

          Section 7.01. Company to Furnish Trustee Names and Addresses of
                        -------------------------------------------------
Holders.
- ------- 

          The Company will furnish or cause to be furnished to the Trustee with
respect to Registered Securities of each series for which it acts as Trustee:

          (a) semi-annually on a date not more than 15 days after each Regular
Record Date with respect to an Interest Payment Date, if any, for the Registered
Securities of such series (or on semi-annual dates in each year to be determined
pursuant to Section 3.01 if the Registered Securities of such series do not bear
interest), a list, in such form as the Trustee may reasonably require, of the
names and addresses of the Registered Holders as of the date 15 days next
preceding each such Regular Record Date (or such semi-annual dates, as the case
may be); and

          (b) at such other times as the Trustee may request in writing, within
30 days after the receipt by the Company of any such request, a list of similar
form and content as of a date not more than 15 days prior to the time such list
is furnished;

                                       49
<PAGE>
 
provided, however, that if and so long as the Trustee shall be the Security
- --------  -------                                                          
Registrar for such series, no such list need be furnished.

          Section 7.02. Preservation of Information; Communication to Holders.
                        ----------------------------------------------------- 

          (a) The Trustee shall preserve, in as current a form as is reasonably
practicable, all information as to the names and addresses of Holders contained
in the most recent list furnished to the Trustee as provided in Section 7.01
received by it in the capacity of Paying Agent (if so acting) hereunder, and
filed with it within the two preceding years pursuant to Section 7.03(c)(2).

          The Trustee may destroy any list furnished to it as provided in
Section 7.01 upon receipt of a new list so furnished, destroy any information
received by it as Paying Agent (if so acting) hereunder upon delivering to
itself as Trustee, not earlier than 45 days after an Interest Payment Date, a
list containing the names and addresses of the Holders obtained from such
information since the delivery of the next previous list, if any, destroy any
list delivered to itself as Trustee which was compiled from information received
by it as Paying Agent (if so acting) hereunder upon the receipt of a new list so
delivered, and destroy not earlier than two years after filing, any information
filed with it pursuant to Section 7.03(c)(2).

          (b)If three or more Holders (hereinafter referred to as "applicants")
apply in writing to the Trustee, and furnish to the Trustee proof reasonably
satisfactory to the Trustee that each such applicant has owned a Debt Security
for a period of at least six months preceding the date of such application, and
such application states that the applicants desire to communicate with other
Holders of Debt Securities of a particular series (in which case the applicants
must hold Debt Securities of such series) or with all Holders of Debt Securities
with respect to their rights under this Indenture or under the Debt Securities
and is accompanied by a copy of the form of proxy or other communication which
such applicants propose to transmit, then the Trustee shall, within five
Business Days after the receipt of such application, at its election, either

          (i) afford such applicants access to the information preserved at the
     time by the Trustee in accordance with Section 7.02(a), or

          (ii) inform such applicants as to the approximate number of Holders of
     Debt Securities of such series or of all Debt Securities, as the case may
     be, whose names and addresses appear in the information preserved at the
     time by the Trustee in accordance with Section 7.02(a), and as to the
     approximate cost of mailing to such Holders the form of proxy or other
     communication, specified in such application.

          If the Trustee shall elect not to afford such applicants access to
such information, the Trustee shall, upon written request of such applicants,
mail to the Holders of Debt Securities of such series or all Holders, as the
case may be, whose names and addresses appear in the information preserved at
the time by the Trustee in accordance with Section 7.02(a), a copy of the form
of proxy or other communication which is specified in such request, with
reasonable promptness after a tender to the Trustee of the material to be mailed
and of payment, or provision for the payment, of the reasonable expenses of
mailing, unless within five days after such tender, the Trustee shall mail to
such applicants and file with the Commission, together with a copy of the
material to be mailed, a written statement to the effect that, in the opinion of
the Trustee, such mailing would be contrary to the best interests of the Holders
of Debt Securities of such series or all Holders, as the case may be, or would
be in violation of applicable law.  Such written statement shall specify the
basis of such opinion.  If the Commission, after

                                       50
<PAGE>
 
opportunity for a hearing upon the objections specified in the written statement
so filed, shall enter an order refusing to sustain any of such objections or if
after the entry of an order sustaining one or more of such objections, the
Commission shall find, after notice and opportunity for hearing, that all the
objections so sustained have been met and shall enter an order so declaring, the
Trustee shall mail copies of such material to all such Holders with reasonable
promptness after the entry of such order and the renewal of such tender;
otherwise the Trustee shall be relieved of any obligation or duty to such
applicants respecting their application.

          (c) Every Holder of Debt Securities, by receiving and holding the
same, agrees with the Company and the Trustee that neither the Company nor the
Trustee shall be held accountable by reason of the disclosure of any such
information as to the names and addresses of the Holders in accordance with
Section 7.02(b), regardless of the source from which such information was
derived, and that the Trustee shall not be held accountable by reason of mailing
of any material pursuant to a request made under Section 7.02(b).

it acts as Trustee, in the manner hereinafter provided in this Section 7.03, a
brief report dated such date with respect to any of the following events which
may have occurred within the previous 12 months (but if no such event has

     and for the reimbursement of which it claims or may claim a lien or charge,
     prior to that of the Debt Securities of such series, on any property or
     funds held or collected by it as Trustee, except that the Trustee shall not
     be required (but may elect) to report such advances if such advances so
     remaining unpaid aggregate not more than 1/2 of 1% of the principal amount
     of the Outstanding Debt Securities of such series on the date of such
     report;

          (4) any change to the amount, interest rate and maturity date of all
     other indebtedness owing by the Company (or any other obligor on the Debt
     Securities of such series) to the Trustee in its individual capacity, on

     (4) or (6);

          (5) any change to the property and funds, if any, physically in the

<PAGE>
 
          (6) any additional issue of Debt Securities which the Trustee has not
     previously reported; and

          (7) any action taken by the Trustee in the performance of its duties
     hereunder which it has not previously reported and which in its opinion
     materially affects the Debt Securities of such series, except action in
     respect of a default, notice of which has been or is to be withheld by the
     Trustee in accordance with Section 6.02.

          (b) The Trustee shall transmit by mail to all Holders of Debt
Securities of any series (whose names and addresses appear in the information
preserved at the time by the Trustee in accordance with Section 7.02 (a)) for
which it acts as the Trustee, as hereinafter provided, a brief report with
respect to the character and amount of any advances (and if the Trustee elects
so to state, the circumstances surrounding the making thereof) made by the
Trustee (as such) since the date of the last report transmitted pursuant to
subsection (a) of this Section (or if no such report has yet been so
transmitted, since the date of execution of this instrument) for the
reimbursement of which it claims or may claim a lien or charge, prior to that of
the Debt Securities of such series, on property or funds held or collected by it
as Trustee, and which it has not previously reported pursuant to this
subsection, except that the Trustee for each series shall not be required (but
may elect) to report such advances if such advances remaining unpaid at any time
aggregate 10% or less of the principal amount of the Debt Securities of such
series Outstanding at such time, such report to be transmitted within 90 days
after such time.

          (c) Reports pursuant to this Section 7.03 shall be transmitted by

     addresses of such Holders of Registered Securities appear in the Security
     Register; and

     Section 7.03, to each Holder of a Debt Security of any series whose name
     and address appear in the information preserved at the time by the Trustee
     in accordance with Section 7.02(a).

          (d)  A copy of each such report shall, at the time of such
transmission to Holders, be filed by the Trustee with each stock exchange upon
which any Debt Securities of such series are listed, with the Commission and
also with the Company.  The Company will notify the Trustee when any series of
Debt Securities are listed on any stock exchange.

          Section 7.04. Reports by Company.
                        ------------------ 

          Unless otherwise specified with respect to a particular series of Debt
Securities pursuant to Section 3.01, the Company will:

          (1) file with the Trustee, within 15 days after the Company is
     required to file the same with the Commission, copies of the annual reports
     and of the information, documents and other reports (or copies of such
     portions of any of the foregoing as the Commission may from time to time by
     rules and regulations prescribe) which the Company may be required to file
     with the Commission pursuant to Section 13 or Section 15(d) of the
     Securities Exchange Act of 1934, as amended.  Notwithstanding that the
     Company may not be required to remain subject to the reporting requirements
     of Section 13 or 15(d) of the Securities Exchange Act of 1934, as amended,
     or otherwise report on an annual and quarterly basis on forms provided for
     such annual and quarterly reporting pursuant to rules and regulations
     promulgated by the Commission, the

<PAGE>
 
     Company shall continue to file with the Commission and provide the Trustee
     and the Holders of each series of Debt Securities with, without cost to

                             CONCERNING THE HOLDERS

          Section 8.01. Acts of Holders.
                        --------------- 

          Any request, demand, authorization, direction, notice, consent, waiver
or other action provided by this Indenture to be given or taken by Holders may
be embodied in and evidenced by one or more instruments of substantially similar
tenor signed by such Holders in person or by an agent or proxy duly appointed in
writing; and, except as herein otherwise expressly provided, such action shall
become effective when such instrument or instruments are delivered to the
Trustee, and, where it is hereby expressly required, to the Company.  Such
instrument or instruments (and the action embodied therein and evidenced
thereby) are herein sometimes referred to as the "Act" of the Holders signing
such instrument or instruments.  Whenever in this Indenture it is provided that
the Holders of a specified percentage in aggregate principal amount of the
Outstanding Debt Securities of any series may take any Act, the fact that the
Holders of such specified percentage have joined therein may be evidenced (a) by
the instrument or instruments executed by Holders in person or by agent or proxy
appointed in writing, or (b) by the record of Holders voting in favor thereof at
any meeting of such Holders duly called and held in accordance with the
provisions of Article Nine, or (c) by a combination of such instrument or
instruments and any such record of such a meeting of Holders.

by Holder.
- --------- 

          The ownership of Registered Securities of any series shall be proved
by the Security Register for such series or by a certificate of the Security
Registrar for such series.

          Subject to the provisions of Sections 6.01, 6.03 and 9.05, proof of
the execution of a writing appointing an agent or proxy and of the execution of
any instrument by a Holder or his agent or proxy shall be sufficient and
conclusive in favor of the Trustee and the Company if made in the following
manner:

          The fact and date of the execution by any such person of any
instrument may be proved by the certificate of any notary public or other
officer authorized to take acknowledgements of deeds, that the person executing
such instrument acknowledged to him the execution thereof, or by an affidavit of
a witness to such execution sworn to before any such notary or other such
officer.  Where such execution is by an officer of a corporation or association
or a member of a partnership on behalf of such corporation, association or
partnership, as the case may be, or by any other person acting in a
representative capacity, such certificate or affidavit shall also constitute
sufficient proof of his authority.

          The record of any Holders' meeting shall be proved in the manner
provided in Section 9.06.

          The Trustee may in any instance require further proof with respect to
any of the matters referred to in this Section so long as the request is a
reasonable one.

          Section 8.03. Persons Deemed Owners.
                        --------------------- 

          The Company, the Trustee and any agent of the Company or the Trustee
may treat the Person in whose name any Registered Security is registered as the
owner of such Registered Security for the purpose of receiving payment of the
principal of (and premium, if any) and (subject to Section 3.07) interest, if
any, on such Registered Security and for all other purposes whatsoever, whether
or not such Registered Security be overdue, and neither the Company, the Trustee
nor any agent of the Company or the Trustee shall be affected by notice to the
contrary.  All payments made to any Holder, or upon his order, shall be valid,
and, to the extent of the sum or sums paid, effectual to satisfy and discharge
the liability for moneys payable upon such Debt Security.

          Section 8.04. Revocation of Consents; Future Holders Bound.
                        -------------------------------------------- 

          At any time prior to (but not after) the evidencing to the Trustee, as
provided in Section 8.01, of the taking of any Act by the Holders of the
percentage in aggregate principal amount of the Outstanding Debt Securities
specified in this Indenture in connection with such Act, any Holder of a Debt
Security the number, letter or other distinguishing symbol of which is shown by
the evidence to be included in the Debt Securities the Holders of which have
consented to such Act may, by filing written notice with the Trustee at the
Corporate Trust Office and upon proof of ownership as provided in Section 8.02,
revoke such Act so far as it concerns such Debt Security.  Except as aforesaid,
any such Act taken by the Holder of any Debt Security shall be conclusive and
binding upon such Holder and, subject to the provisions of Section 5.08, upon
all future Holders of such Debt Security and of any Debt Securities issued on
transfer or in lieu thereof or in exchange or substitution therefor,
irrespective of whether or not any notation in regard thereto is made upon such
Debt Security or such other Debt Securities.

and such other matters concerning the conduct of the meeting as it shall deem
appropriate.

          The Trustee shall, by an instrument in writing, appoint a temporary

          It shall not be necessary for any Act of Holders under this Section to
approve the particular form of any proposed supplemental indenture, but it shall
be sufficient if such Act shall approve the substance thereof.

          A supplemental indenture which changes or eliminates any covenant or
other provision of this Indenture with respect to one or more particular series
of Debt Securities or which modifies the rights of the Holders of Debt
Securities of such series with respect to such covenant or other provision,
shall be deemed not to affect the rights under this Indenture of the Holders of
Debt securities of any other series.

otherwise in a material way.

                             --------------------------------- 

          Upon the execution of any supplemental indenture under this Article,
this Indenture shall be modified in accordance therewith, and such supplemental
indenture shall form a part of this Indenture for all purposes; and every Holder
of Debt Securities theretofore or thereafter authenticated and delivered
hereunder shall be bound thereby.

execution of any supplemental indenture pursuant to this Article may, and shall
if required by the Trustee, bear a notation in form approved by the Trustee as

so determine, new Debt Securities of any series so modified as to conform, in
the opinion of the Trustee and the Board of Directors, to any such supplemental
indenture may be prepared and executed by the Company and authenticated and
delivered by the Trustee in exchange for Outstanding Debt Securities of such
series.

          Promptly after the execution by the Company and the appropriate
Trustee of any supplemental indenture pursuant to Section 11.02, the Company

                          ------------------------------------------ 

          The Company covenants and agrees for the benefit of each series of
Debt Securities that it will duly and punctually pay the principal of (and
premium, if any) and interest on the Debt Securities in accordance with the
terms of the Debt Securities and this Indenture.  If so provided in the terms of
any series of Debt Securities established as provided in Section 3.01, the
interest, if any, due in respect of any temporary Global Note or permanent
Global Note, together with any additional amounts payable in respect thereof, as
provided in the terms and conditions of such Debt Security, shall be payable
only upon presentation of such Debt Security to the Trustee for notation thereon
of the payment of such interest.

          Section 12.02.  Officer's Certificate as to Default.
                          ----------------------------------- 

          Unless otherwise specifically provided for with respect to any series
of Debt Securities under Section 3.01, the Company will deliver to the Trustee,
on or before a date not more than four months after the end of each fiscal year
of the Company (which on the date hereof is the calendar year) ending after the
date hereof, a certificate of the principal executive officer, principal
financial officer or principal accounting officer of the Company stating whether
or not to the best knowledge of the signer thereof the Company is in compliance
with all covenants and conditions under this Indenture, and, if the Company
shall be in default, specifying all such defaults and the nature thereof of
which such signer may have knowledge.  For purposes of this Section, such
compliance shall be determined without regard to any period of grace or
requirement of notice provided under this Indenture.

          If Debt Securities of a series are issuable only as Registered
Securities, the Company will maintain in each Place of Payment for such series
an office or agency where Debt Securities of that series may be presented or
surrendered for payment, where Debt Securities of that series may be surrendered
for registration of transfer or exchange, where Debt Securities of that series
that are convertible may be surrendered for conversion, if applicable, and where
notices and demands to or upon the Company in respect of the Debt Securities of
that series and this Indenture may be served.  The Company will 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 and the Company hereby
appoints the Trustee as its agent to receive all presentations, surrenders,
notices and demands.

          The Company may also from time to time designate different or
additional offices or agencies to be maintained for such purposes (in or outside
of such Place of Payment), and may from time to time rescind any such
designations.  The Company will give prompt written notice to the Trustee of any
such additional designation or rescission of designation and any change in the
location of any such different or additional office or agency.

Trust.
- ----- 

          If the Company shall at any time act as its own Paying Agent with
respect to any series of Debt Securities it will, on or before each due date of
the principal of (and premium, if any) or interest on any of the Debt Securities
of such series, segregate and hold in trust for the benefit of the Persons
entitled thereto a sum sufficient to pay the principal (and premium, if any) or
interest so becoming due until such sums shall be paid to such Persons or
otherwise disposed of as herein provided, and will promptly notify the Trustee
of its action or failure so to act.

          Whenever the Company shall have one or more Paying Agents with respect
to any series of Debt Securities, it will, by or on each due date of the
principal (and premium, if any) or interest on any Debt Securities of such
series, deposit with any such Paying Agent a sum sufficient to pay the principal
(and premium, if any) or interest so becoming due, such sum to be held in trust
for the benefit of the Persons entitled thereto, and (unless any such Paying
Agent is the Trustee) the Company will promptly notify the Trustee of its action
or failure so to act.

          The Company will cause each Paying Agent with respect to any series of
Debt Securities other than the Trustee to execute and deliver to the Trustee an
instrument in which such Paying Agent shall agree with the Trustee, subject to
the provisions of this Section, that such Paying Agent will:

          (1) hold all sums held by it for the payment of the principal of (and
     premium, if any) or interest on Debt Securities of such series in trust for
     the benefit of the Persons entitled thereto until such sums shall be paid
     to such Persons or otherwise disposed of as herein provided;

          (2) give the Trustee notice of any default by the Company (or any
     other obligor upon the Debt Securities of such series) in the making of any
     payment of principal (and premium, if any) or interest on the Debt
     Securities of such series; and

          (3) at any time during the continuance of any such default, upon the
     written request of the Trustee, forthwith pay to the Trustee all sums so
     held in trust by such Paying Agent.

                                       62
<PAGE>
 
          The Company may at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture or for any other purpose, pay, or
by Company Order direct any Paying Agent to pay, to the Trustee all sums held in
trust by the Company or such Paying Agent, such sums to be held by the Trustee
upon the same trusts as those upon which such sums were held by the Company or
such Paying Agent; and, upon such payment by any Paying Agent to the Trustee,
such Paying Agent shall be released from all further liability with respect to
such money.

          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 (and premium, if
any) or interest on any Debt Security of any series 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 upon Company Request, or (if then held
by the Company) shall be discharged from such trust; and the Holder of such Debt
Security shall thereafter, as an unsecured general 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 transmitted in the manner and to the extent
provided by Section 1.05, 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, any unclaimed balance of such money then remaining
will be repaid to the Company.

          Section 12.05.     Corporate Existence.
                             ------------------- 

          Subject to Article Ten, the Company will do or cause to be done all
things necessary to preserve and keep in full force and effect its corporate
existence, rights (charter and statutory) and franchises; provided, however,
                                                          --------  ------- 
that the Company shall not be required to preserve any such right or franchise
if the Company shall determine that the preservation thereof is no longer
desirable in the conduct of the business of the Company.

                               --------------------------- 

          The Company may omit in any particular instance to comply with any
term, provision or condition set forth in Section 12.05 (and, if so specified
pursuant to Section 3.01, any other covenant not set forth herein and specified
pursuant to Section 3.01 to be applicable to the Securities of any series,
except as otherwise provided pursuant to Section 3.01) with respect to the Debt
Securities of any series if before the time for such compliance the Holders of
at least a majority in principal amount of the Outstanding Debt Securities of
such series shall, by Act of such Holders, either waive such compliance in such
instance or generally waive compliance with such term, provision or condition,
but no such waiver shall extend to or affect such term, provision or condition
except to the extent expressly so waived, and, until such waiver shall become
effective, the obligations of the Company and the duties of the Trustee in
respect of any such term, provision or condition shall remain in full force and
effect.

                         REDEMPTION OF DEBT SECURITIES

          Section 13.01.  Applicability of Article.
                          ------------------------ 

          Debt Securities of any series which are redeemable before their
Maturity shall be redeemable in accordance with their terms and (except as
otherwise specified pursuant to Section 3.01 for Debt Securities of any series)
in accordance with this Article.

          Section 13.02.  Election to Redeem; Notice to Trustee.
                          ------------------------------------- 

          The election of the Company to redeem (or, in the case of Discount
Securities, to permit the Holders to elect to surrender for redemption) any Debt
Securities shall be evidenced by a Board Resolution.  In case of any redemption
at the election of the Company of less than all of the Debt Securities of any
series pursuant to Section 13.03, the Company shall, at least 60 days before the
Redemption Date fixed by the Company (unless a shorter notice shall be
satisfactory to the Trustee), notify the Trustee of such Redemption Date and of
the principal amount of Debt Securities of such series to be redeemed.  In the
case of any redemption of Debt Securities prior to the expiration of any
restriction on such redemption provided in the terms of such Debt Securities or
elsewhere in this Indenture, the Company shall furnish the Trustee with an
Officers' Certificate evidencing compliance with such restrictions.

          Section 13.03.  Selection by Trustee of Debt Securities to Be 
                          ---------------------------------------------
Redeemed.
- --------

          Except in the case of a redemption in whole of the Registered
Securities of such series, if less than all the Debt Securities of any series
are to be redeemed at the election of the Company, the particular Debt
Securities to be redeemed shall be selected not more than 60 days prior to the
Redemption Date by the Trustee, from the Outstanding Debt Securities of such
series not previously called for redemption, by such method as the Trustee shall
deem fair and appropriate and which may provide for the selection for redemption
of portions (equal to the minimum authorized denomination for Debt Securities of
such series or any integral multiple thereof) of the principal amount of Debt
Securities of such series in a denomination larger than the minimum authorized
denomination for Debt Securities of such series pursuant to Section 3.02.  The
portions of the principal amount of Debt Securities so selected for partial
redemption shall be equal to the minimum authorized denominations for Debt
Securities of such series pursuant to Section 3.02 or any integral multiple
thereof, except as otherwise set forth in the applicable form of Debt
Securities.  In any case when more than one Registered Security of such series
is registered in the same name, the Trustee in its discretion may treat the
aggregate principal amount so registered as if it were represented by one
Registered Security of such series.

          The Trustee shall promptly notify the Company in writing of the Debt
Securities selected for redemption and, in the case of any Debt Securities
selected for partial redemption, the principal amount thereof to be redeemed.

          For all purposes of this Indenture, unless the context otherwise
requires, all provisions relating to the redemption of Debt Securities shall
relate, in the case of any Debt Security redeemed or to be redeemed only in
part, to the portion of the principal amount of such Debt security which has
been or is to be redeemed.

          Section 13.04.  Notice of Redemption.
                          -------------------- 

          Notice of redemption shall be given by the Company, or at the
Company's request, by the Trustee in the name and at the expense of the Company,
not less than 30 days and not more than 60 days prior to the Redemption Date to
the Holders of Debt Securities of any series to be redeemed in whole or in part
pursuant to this Article Thirteen, in the manner provided in Section 1.05.  Any
notice so given shall be conclusively presumed to have been duly given, whether
or not the Holder receives such notice.  Failure to give such notice, or any
defect in such notice to the Holder of any Debt Security of a series designated
for redemption, in whole or in part, shall not affect the sufficiency of any
notice of redemption with respect to the Holder of any other Debt Security of
such series.

          All notices of redemption shall state:

          (1)  the Redemption Date,

          (2)  the Redemption Price,

          (3) that Debt Securities of such series are being redeemed by the
     Company pursuant to provisions contained in this Indenture or the terms of
     the Debt Securities of such series or a supplemental indenture establishing
     such series, if such be the case, together with a brief statement of the
     facts permitting such redemption,

          (4) if less than all Outstanding Debt Securities of any series are to
     be redeemed, the identification (and, in the case of partial redemption,
     the principal amounts) of the particular Debt Securities to be redeemed,

          (5) that on the Redemption Date the Redemption Price will become due
     and payable upon each such Debt Security to be redeemed, and that interest
     thereon, if any, shall cease to accrue on and after said date,

          (6) the Place or Places of Payment where such Debt Securities are to
     be surrendered for payment of the Redemption Price, and

          (7) that the redemption is for a sinking fund, if such is the case.

          Section 13.05.  Deposit of Redemption Price.
                          --------------------------- 

          On or prior to the Redemption Date for any Debt Securities, the
Company shall deposit with the Trustee or with a Paying Agent (or, if the
Company is acting as its own Paying Agent, segregate and hold in trust as
provided in Section 12.04) an amount of money sufficient to pay the Redemption
Price of such Debt Securities or any portions thereof which are to be redeemed
on that date.

          Section 13.06.  Debt Securities Payable on Redemption Date.
                          ------------------------------------------ 

          Notice of redemption having been given as aforesaid, any Debt
Securities so to be redeemed shall, on the Redemption Date, become due and
payable at the Redemption Price  and from and after such date (unless the
Company shall default in the payment of the Redemption Price) such Debt
Securities shall cease to bear interest.  Upon surrender of any such Debt
Security for redemption in accordance with said notice, such Debt Security shall
be paid by the Company at the Redemption Price;

                                       65
<PAGE>
 
provided, however, that, unless otherwise specified as contemplated by Section
- --------  -------                                                             
3.01, installments of interest on Registered Securities which have a Stated
Maturity on or prior to the Redemption Date for such Debt Securities shall be
payable according to the terms of such Debt Securities and the provisions of
Section 3.07.

          If any Debt Security called for redemption shall not be so paid upon
surrender thereof for redemption, the principal (and premium, if any) shall,
until paid, bear interest from the Redemption Date at the rate prescribed
therefor in the Debt Security.

          Section 13.07. Dent Securities Redeemed in Part.
                         -------------------------------- 

          Any Debt Security which is to be redeemed only in part shall be
surrendered at the Corporate Trust Office or such other office or agency of the
Company as is specified pursuant to Section 3.01 with, if the Company, the
Security Registrar or the Trustee so requires, due endorsement by, or a written
instrument of transfer in form satisfactory to the Company, the Security
Registrar and the Trustee duly executed by, the Holder thereof or his attorney
duly authorized in writing, and the Company shall execute, and the Trustee shall
authenticate and deliver to the Holder of such Debt Security without service
charge, a new Debt Security or Debt Securities of the same series, of like tenor
and form, of any authorized denomination as requested by such Holder in
aggregate principal amount equal to and in exchange for the unredeemed portion
of the principal of the Debt Security so surrendered.  In the case of a Debt
Security providing appropriate space for such notation, at the option of the
Holder thereof, the Trustee, in lieu of delivering a new Debt Security or Debt
Securities as aforesaid, may make a notation on such Debt Security of the
payment of the redeemed portion thereof.


                               ARTICLE FOURTEEN

                                 SINKING FUNDS

          Section 14.01.  Applicability of Article.
                          ------------------------ 

          The provisions of this Article shall be applicable to any sinking fund
for the retirement of Debt Securities of a series except as otherwise specified
pursuant to Section 3.01 for Debt Securities of such series.

          The minimum amount of any sinking fund payment provided for by the
terms of Debt Securities of any series is herein referred to as a "mandatory
sinking fund payment," and any payment in excess of such minimum amount provided
for by the terms of Debt Securities of any series is herein referred to as an
"optional sinking fund payment."  If provided for by the terms of Debt
Securities of any series, the amount of any cash sinking fund payment may be
subject to reduction as provided in Section 14.02.  Each sinking fund payment
shall be applied to the redemption of Debt Securities of any series as provided
for by the terms of Debt Securities of such series.

          Section 14.02.  Satisfaction of Mandatory Sinking Fund Payments
                          -----------------------------------------------
with Debt Securities.
- -------------------- 

          In lieu of making all or any part of a mandatory sinking fund payment
with respect to any Debt Securities of a series in cash, the Company may at its
option, at any time no more than sixteen months and no less than 45 days prior
to the date on which such sinking fund payment is due, deliver to the Trustee
Debt Securities of such series theretofore purchased or otherwise acquired by
the

                                       66
<PAGE>
 
Company, except Debt Securities of such series which have been redeemed through
the application of mandatory sinking fund payments pursuant to the terms of the
Debt Securities of such series, accompanied by a Company Order instructing the
Trustee to credit such obligations and stating that the Debt Securities of such
series were originally issued by the Company by way of bona fide sale or other
negotiation for value, provided that such Debt Securities shall not have been
                       --------                                              
previously so credited.  Such Debt Securities shall be received and credited for
such purpose by the Trustee at the Redemption Price specified in such Debt
Securities for redemption through operation of the sinking fund and the amount
of such mandatory sinking fund payment shall be reduced accordingly.

          Section 14.03.  Redemption of Debt Securities for Sinking Fund.
                          ---------------------------------------------- 

          Not less than 60 days prior to each sinking fund payment date for any
series of Debt Securities (unless a shorter period shall be satisfactory to the
Trustee), the Company will deliver to the Trustee an Officers' Certificate
specifying the amount of the next ensuing sinking fund payment for that series
pursuant to the terms of that series, the portion thereof, if any, which is to
be satisfied by payment of cash and the portion thereof, if any, which is to be
satisfied by delivering and crediting Debt Securities of such series pursuant to
Section 14.02 and whether the Company intends to exercise its rights to make a
permitted optional sinking fund payment with respect to such series.  Such
certificate shall be irrevocable and upon its delivery the Company shall be
obligated to make the cash payment or payments therein referred to, if any, on
or before the next succeeding sinking fund payment date.  In the case of the
failure of the Company to deliver such certificate, the sinking fund payment due
on the next succeeding sinking fund payment date for such series shall be paid
entirely in cash and shall be sufficient to redeem the principal amount of the
Debt Securities of such series subject to a mandatory sinking fund payment
without the right to deliver or credit Debt Securities as provided in Section
14.02 and without the right to make any optional sinking fund payment with
respect to such series at such time.

          Any sinking fund payment or payments (mandatory or optional) made in
cash plus any unused balance of any preceding sinking fund payments made with
respect to the Debt Securities of any particular series shall be applied by the
Trustee (or by the Company if the Company is acting as its own Paying Agent) on
the sinking fund payment date on which such payment is made (or, if such payment
is made before a sinking fund payment date, on the sinking fund payment date
immediately following the date of such payment) to the redemption of Debt
Securities of such series at the Redemption Price specified in such Debt
Securities with respect to the sinking fund.  Any sinking fund moneys not so
applied or allocated by the Trustee (or by the Company if the Company is acting
as its own Paying Agent) to the redemption of Debt Securities shall be added to
the next sinking fund payment received by the Trustee (or if the Company is
acting as its own Paying Agent, segregated and held in trust as provided in
Section 12.04) for such series and, together with such payment (or such amount
so segregated) shall be applied in accordance with the provisions of this
Section.  Any and all sinking fund moneys with respect to the Debt Securities of
any particular series held by the Trustee (or if the Company is acting as its
own Paying Agent, segregated and held in trust as provided in Section 12.04) on
the last sinking fund payment date with respect to Debt Securities of such
series and not held for the payment or redemption of particular Debt Securities
of such series shall be applied by the Trustee (or by the Company if the Company
is acting as its own Paying Agent), together with other moneys, if necessary, to
be deposited (or segregated) sufficient for the purpose, to the payment of the
principal of the Debt Securities of such series at Maturity.

          The Trustee shall select or cause to be selected the Debt Securities
to be redeemed upon such sinking fund payment date in the manner specified in
Section 13.03 (unless otherwise specified pursuant to Section 3.01) and the
Company shall cause notice of the redemption thereof to be given in

                                       67

the manner provided in Section 13.04.  Such notice having been duly given, the
redemption of such Debt Securities shall be made upon the terms and in the
manner stated in Section 13.06.

          On or before each sinking fund payment date, the Company shall pay to
the Trustee (or, if the Company is acting as its own Paying Agent, the Company
shall segregate and hold in trust as provided in Section 12.04) in cash a sum,
equal to the principal and any interest accrued to the Redemption Date for Debt
Securities or portions thereof to be redeemed on such sinking fund payment date
pursuant to this Section.

          Neither the Trustee nor the Company shall redeem any Debt Securities
of a series with sinking fund moneys or mail any notice of redemption of Debt
Securities of such series by operation of the sinking fund for such series
during the continuance of a default in payment of interest, if any, on any Debt
Securities of such series or of any Event of Default (other than an Event of
Default occurring as a consequence of this paragraph) with respect to the Debt
Securities of such series, except that if the notice of redemption shall have
been provided in accordance with the provisions hereof, the Trustee (or the
Company, if the Company is then acting as its own Paying Agent) shall redeem
such Debt Securities if cash sufficient for that purpose shall be deposited with
the Trustee (or segregated by the Company) for that purpose in accordance with
the terms of this Article.  Except as aforesaid, any moneys in the sinking fund
for such series at the time when any such default or Event of Default shall
occur and any moneys thereafter paid into such sinking fund shall, during the
continuance of such default or Event of Default, be held as security for the
payment of the Debt Securities of such series; provided, however, that in case
                                               --------  -------              
such default or Event of Default shall have been cured or waived as provided
herein, such moneys shall thereafter be applied on or prior to the next sinking
fund payment date for the Debt Securities of such series on which such moneys
may be applied pursuant to the provisions of this Section.

          Section 15.01.   Applicability of Article.
                           ------------------------ 

          If, pursuant to Section 3.01, provision is made for the defeasance of
Debt Securities of a series, then the provisions of this Article shall be
applicable except as otherwise specified pursuant to Section 3.01 for Debt
Securities of such series.

          Section 15.02.   Defeasance Upon Deposit of Moneys or U.S.
                           -----------------------------------------
Government Obligations.
- ---------------------- 

          At the Company's option, either (a) the Company shall be deemed to
have been Discharged (as defined below) from its obligations with respect to
Debt Securities of any series ("legal defeasance option") or (b) the Company
shall cease to be under any obligation to comply with any term, provision or
condition set forth in Section 10.01 with respect to Debt Securities of any
series (and, if so specified pursuant to Section 3.01, any other obligation of
the Company or restrictive covenant added for the benefit of such series
pursuant to Section 3.01) ("covenant defeasance option") at any time after the
applicable conditions set forth below have been satisfied:

          (1) the Company shall have deposited or caused to be deposited
     irrevocably with the Trustee as trust funds in trust, specifically pledged
     as security for, and dedicated solely to, the benefit of the Holders of the
     Debt Securities of such series (i) money in an amount, or (ii) U.S.

                                       68
<PAGE>
 
     Government Obligations (as defined below) which through the payment of
     interest and principal in respect thereof in accordance with their terms
     will provide, not later than one day before the due date of any payment,
     money in an amount, or (iii) a combination of (i) and (ii), sufficient, in
     the opinion (with respect to (i) and (ii)) of a nationally recognized firm
     of independent public accountants expressed in a written certification
     thereof delivered to the Trustee, to pay and discharge each installment of
     principal (including any mandatory sinking fund payments) of and premium,
     if any, and interest on, the Outstanding Debt Securities of such series on
     the dates such installments of interest or principal and premium are due;

          (2) such deposit shall not cause the Trustee with respect to the Debt
     Securities of that series to have a conflicting interest as defined in
     Section 6.08 and for purposes of the Trust Indenture Act with respect to
     the Debt Securities of any series;

          (3) such deposit will not result in a breach or violation of, or
     constitute a default under, this Indenture or any other agreement or
     instrument to which the Company is a party or by which it is bound;

          (4) if the Debt Securities of such series are then listed on any
     national securities exchange, the Company shall have delivered to the
     Trustee an Opinion of Counsel or a letter or other document from such
     exchange to the effect that the Company's exercise of its option under this
     Section would not cause such Debt Securities to be delisted;

          (5) no Event of Default or event (including such deposit) which, with
     notice or lapse of time or both, would become an Event of Default with
     respect to the Debt Securities of such series shall have occurred and be
     continuing on the date of such deposit and, with respect to the legal
     defeasance option only, no Event of Default under Section 5.01(5) or
     Section 5.01(6) or event which with the giving of notice or lapse of time,
     or both, would become an Event of Default under Section 5.01(5) or Section
     5.01(6) shall have occurred and be continuing on the 91st day after such
     date; and

          (6) the Company shall have delivered to the Trustee an Opinion of
     Counsel or a ruling from the Internal Revenue Service to the effect that
     the Holders of the Debt Securities of such series will not recognize
     income, gain or loss for Federal income tax purposes as a result of such
     deposit, defeasance or Discharge.

Notwithstanding the foregoing, if the Company exercises its covenant defeasance
option and an Event of Default under Section 5.01(5) or Section 5.01(6) or event
which with the giving of notice or lapse of time, or both, would become an Event
of Default under Section 5.01(5) or Section 5.01(6) shall have occurred and be
continuing on the 91st day after the date of such deposit, the obligations of
the Company referred to under the definition of covenant defeasance option with
respect to such Debt Securities shall be reinstated.  Money and securities held
in trust pursuant to a legal defeasance shall not be subject to Article Sixteen.

          "Discharged" means that the Company shall be deemed to have paid and
discharged the entire indebtedness represented by, and obligations under, the
Debt Securities of such series and to have satisfied all the obligations under
this Indenture relating to the Debt Securities of such series (and the Trustee,
at the expense of the Company, shall execute proper instruments acknowledging
the same), except (A) the rights of Holders of Debt Securities of such series to
receive, from the trust fund described in clause (1) above, payment of the
principal of (and premium, if any) and interest on such Debt

                                       69

Securities when such payments are due, (B) the Company's obligations with
respect to the Debt Securities of such series under Sections 3.04, 3.05, 3.06,
12.03 and 15.03 and (C) the rights, powers, trusts, duties and immunities of the
Trustee hereunder.

          "U.S. Government Obligations" means securities that are (a) direct
obligations of the United States of America for the timely payment of which its
full faith and credit is pledged or (b) obligations of a Person controlled or
supervised by and acting as an agency or instrumentality of the United States of
America the timely payment of which is unconditionally guaranteed as a full
faith and credit obligation by the United States of America, which, in either
case, are not callable or redeemable at the option of the issuer thereof, and
shall also include a depository receipt issued by a bank (as defined in Section
3(a)(2) of the Securities Act), as custodian with respect to any such U.S.
Government Obligation or a specific payment of principal of or interest on any
such U.S. Government Obligation held by such custodian for the account of the
holder of such depository receipt; provided, that (except as required by law)
such custodian is not authorized to make any deduction from the amount payable
to the holder of such depository receipt from any amount received by the
custodian in respect of the U.S. Government Obligation or the specific payment
of principal of or interest on the U.S. Government Obligation evidenced by such
depository receipt.

to Be Held in Trust.
- ------------------- 

          All moneys and U.S. Government Obligations deposited with the Trustee
pursuant to Section 15.02 in respect of Debt Securities of a series shall be
held in trust and applied by it, in accordance with the provisions of such Debt
Securities and this Indenture, to the payment, either directly or through any
Paying Agent (including the Company acting as its own Paying Agent) as the
Trustee may determine, to the Holders of such Debt Securities, of all sums due
and to become due thereon for principal (and premium, if any) and interest, if
any, but such money need not be segregated from other funds except to the extent
required by law.

          Section 15.04.  Repayment to Company.
                          -------------------- 

          The Trustee and any Paying Agent shall promptly pay or return to the
Company upon Company Request any moneys or U.S. Government Obligations held by
them at any time that are not required for the payment of the principal of (and
premium, if any) and interest on the Debt Securities of any series for which
money or U.S. Government Obligations have been deposited pursuant to Section
15.02.

          The provisions of the last paragraph of Section 12.04 shall apply to
any money held by the Trustee or any Paying Agent under this Article that
remains unclaimed for two years after the Maturity of any series of Debt
Securities for which money or U.S. Government Obligations have been deposited
pursuant to Section 15.02.

          Except as otherwise specified pursuant to Section 3.01 for Debt
Securities of any series, the provisions of this Article Sixteen shall be
applicable to any Debt Securities that are convertible into Common Stock or
Preferred Stock.  If so provided pursuant to Section 3.01 with respect to the
Debt Securities of any series, the Holder of a Debt Security of such series
shall have the right, at such Holder's option, to convert, in accordance with
the terms of such series of Debt Securities and this Article Sixteen, all or any
part (in a denomination of, unless otherwise specified pursuant to Section 3.01
with respect to Securities of such series, $1,000 in principal amount or any
integral multiple thereof) of such Debt Security into shares of Common Stock or
Preferred Stock, as the case may be, or, as to any Debt Securities called for
redemption, at any time prior to the time and date fixed for such redemption
(unless the Company shall default in the payment of the Redemption Price, in
which case such right shall not terminate at such time and date).

          Section 16.02.   Conversion Procedure; Conversion Price; Fractional
                           --------------------------------------------------
Shares.
- ------ 

          (a) Each Debt Security to which this Article is applicable shall be
convertible at the office of the Conversion Agent, and at such other place or
places, if any, specified in pursuant to Section 3.01 with respect to the Debt
Securities of such series, into fully paid and nonassessable shares (calculated
to the nearest 1/100th of a share) of Common Stock or Preferred Stock, as the
case may be. The Debt Securities will be converted into shares of Common Stock
or Preferred Stock, as the case may be, at the Conversion Price therefor.  No
payment or adjustment shall be made in respect of dividends on the Common Stock
or Preferred Stock or accrued interest on a converted Debt Security except as
described in Section 16.09.  The Company may, but shall not be required, in
connection with any conversion of Debt Securities, to issue a fraction of a
share of Common Stock or Preferred Stock and, if the Company shall determine not
to issue any such fraction, the Company shall, subject to Section 16.03(4), make
a cash payment (calculated to the nearest cent) equal to such fraction
multiplied by the Closing Price of the Common Stock or Preferred Stock, as the
case may be, on the last Trading Day prior to the date of conversion.

          (b) Before any Holder of a Debt Security shall be entitled to convert
the same into Common Stock or Preferred Stock, such Holder shall surrender such
Debt Security duly endorsed to the Company or in blank, at the office of the
Conversion Agent, or at such other place or places, if any, specified pursuant
to Section 3.01 (in the case of Registered Securities) and at an office of the
Conversion Agent, and shall give written notice to the Company at said office or
place that he elects to convert the same and shall state in writing therein the
principal amount of Debt Securities to be converted and the name or names (with
addresses) in which he wishes the certificate or certificates for Common Stock
or Preferred Stock, as the case may be, to be issued; provided, however, that no
Debt Security or portion thereof shall be accepted for conversion unless the
principal amount of such Debt Security or such portion, when added to the
principal amount of all other Debt Securities or portions thereof then being
surrendered by the Holder thereof for conversion, exceeds the then effective
Conversion Price with respect thereto.  If more than one Debt Security shall be
surrendered for conversion at one time by the same Holder, the number of full
shares of Common Stock or Preferred Stock, as the case may be, which shall be
deliverable upon conversion shall be computed on the basis of the aggregate
principal amount of the Debt Securities (or specified portions thereof to the
extent permitted thereby) so surrendered. Subject to the next succeeding
sentence, the Company will, as soon as practicable thereafter, issue and deliver
at said office or place to such Holder of a Debt Security, or to his nominee or
nominees, certificates for the number of full shares of Common Stock or
Preferred Stock, as the case may be, to which he shall be entitled as aforesaid,
together, subject to the last sentence of paragraph (a) above, with cash in lieu
of any fraction of a share to which he would otherwise be entitled.  The Company
shall not be required to deliver certificates for shares of Common Stock or
Preferred Stock while the stock transfer

                                       71
<PAGE>
 
books for such stock or the Security Register are duly closed for any purpose,
but certificates for shares of Common Stock or Preferred Stock, as the case may
be, shall be issued and delivered as soon as practicable after the opening of
such books or Security Register.  A Debt Security shall be deemed to have been
converted as of the close of business on the date of the surrender of such Debt
Security for conversion as provided above, and the Person or Persons entitled to
receive the Common Stock or Preferred Stock, as the case may be, issuable upon
such conversion shall be treated for all purposes as the record Holder or
Holders of such Common Stock or Preferred Stock as of the close of business on
such date.  In case any Debt Security shall be surrendered for partial
conversion, the Company shall execute and the Trustee shall authenticate and
deliver to or upon the written order of the Holder of the Debt Securities so
surrendered, without charge to such Holder (subject to the provisions of Section
16.08), a new Debt Security or Securities in authorized denominations in an
aggregate principal amount equal to the unconverted portion of the surrendered
Debt Security.

          Section 16.03.  Adjustment of Conversion Price for Common Stock.
                          ----------------------------------------------- 

          The Conversion Price with respect to any Debt Security which is
convertible into Common Stock shall be adjusted from time to time as follows:

          (1) In case the Company shall, at any time or from time to time while
     any of such Debt Securities are outstanding, (i) pay a dividend in shares
     of its Common Stock to holders of Common Stock, (ii) combine its
     outstanding shares of Common Stock into a smaller number of shares of
     Common Stock, (iii) subdivide its outstanding shares of Common Stock into a
     greater number of shares of Common Stock or (iv) make a distribution in
     shares of Common Stock to holders of Common Stock, then the Conversion
     Price in effect immediately before such action shall be adjusted so that
     the Holders of such Debt Securities, upon conversion thereof into Common
     Stock immediately following such event, shall be entitled to receive the
     kind and amount of shares of capital stock of the Company which they would
     have owned or been entitled to receive upon or by reason of such event if
     such Debt Securities had been converted immediately before the record dated
     (or, if no record date, the effective date) for such event. An adjustment
     made pursuant to this Section 16.03(1) shall become effective retroactively
     immediately after the record date in the case of a dividend or distribution
     and shall become effective retroactively immediately after the effective
     date in the case of a subdivision or combination.  For the purposes of this
     Section 16.03(1), each Holder of Debt Securities shall be deemed to have
     failed to exercise any right to elect the kind or amount of securities
     receivable upon the payment of any such dividend, subdivision, combination
     or distribution (provided that if the kind or amount of securities
     receivable upon such dividend, subdivision, combination or distribution is
     not the same for each nonelecting share, then the kind and amount of
     securities or other property receivable upon such dividend, subdivision,
     combination or distribution for each nonelecting share shall be deemed to
     be the kind and amount so receivable per share by a plurality of the
     nonelecting shares).

          (2) In case the Company shall, at any time or from time to time while
     any of such Debt Securities are outstanding, issue rights or warrants to
     all holders of shares of its Common Stock entitling them (for a period
     expiring within 45 days after the record date for such issuance) to
     subscribe for or purchase shares of Common Stock (or securities convertible
     into shares of Common Stock) at a price per share less than the Current
     Market Price of the Common Stock at such record date (treating the price
     per share of the securities convertible into Common Stock as equal to (x)
     the sum of (i) the price for a unit of the security convertible into Common
     Stock and (ii) any additional consideration initially payable upon the
     conversion of such security into

                                       72
<PAGE>
 
     Common Stock divided by (y) the number of shares of Common Stock initially
     underlying such convertible security), the Conversion Price with respect to
     such Debt Securities shall be adjusted so that it shall equal the price
     determined by dividing the Conversion Price in effect immediately prior to
     the date of issuance of such rights or warrants by a fraction, the
     numerator of which shall be the number of shares of Common Stock
     outstanding on the date of issuance of such rights or warrants plus the
     number of additional shares of Common Stock offered for subscription or
     purchase (or into which the convertible securities so offered are initially
     convertible), and the denominator of  which shall be the number of shares
     of Common Stock outstanding on the date of issuance of securities which the
     aggregate offering price of the total number of shares of securities so
     offered for subscription or purchase (or the aggregate purchase price of
     the convertible securities so offered plus the aggregate amount of any
     additional consideration initially payable upon conversion of such
     securities into Common Stock) would purchase at such Current Market Price
     of the Common Stock.  Such adjustment shall become effective retroactively
     immediately after the record date for the determination of stockholders
     entitled to receive such rights or warrants.

          (3) In the case the Company shall, at any time or from time to time
     while any of such Debt Securities are outstanding, distribute to all
     holders of shares of its Common Stock (including any such distribution made
     in connection with a consolidation or merger in which the Company is the
     continuing corporation and the Common Stock is not changed or exchanged)
     cash, evidences of its indebtedness, securities or assets (excluding (i)
     regular periodic cash dividends in amounts, if any, determined from time to
     time by the Board of Directors, (ii) dividends payable in shares of Common
     Stock for which adjustment is made under Section 16.03(1) or (iii) rights
     or warrants to subscribe for or purchase securities of the Company
     (excluding those referred to in Section 16.03(2))), then in each such case
     the Conversion Price with respect to such Debt Securities determined by
     dividing the Conversion Price in effect immediately prior to the date of
     such distribution by a fraction, the numerator of which shall be the
     Current Market Price of the Common Stock on the record date referred to
     below, and the denominator of which shall be such Current Market Price of
     the Common Stock less the then fair market value (as determined by the
     Board of Directors of the Company, whose determination shall be conclusive)
     of the portion of the cash or assets or evidences of indebtedness or
     securities so distributed or of such subscription rights or warrants
     applicable to one share of Common Stock (provided that such denominator
     shall never be less than 1.0); provided however, that no adjustment shall
     be made with respect to any distribution of rights to purchase securities
     of the Company if a Holder of Debt Securities would otherwise be entitled
     to receive such rights upon conversion at any time of such Debt Securities
     into Common Stock unless such rights are subsequently redeemed by the
     Company, in which case such redemption shall be treated for purposes of
     this section as a dividend on the Common Stock.  Such adjustment shall
     become effective retroactively immediately after the record date for the
     determination of stockholders entitled to receive such distribution; and in
     the event that such distribution is not so made, the Conversion Price shall
     again be adjusted to the Conversion Price which would then be in effect if
     such record date had not been fixed.

          (4) The Company shall be entitled to make such additional adjustments
     in the Conversion Price, in addition to those required by subsections
     16.03(1), 16.03(2), and 16.03(03), as shall be necessary in order that any
     dividend or distribution of Common Stock, any subdivision, reclassification
     or combination of shares of Common Stock or any issuance of rights or
     warrants referred to above shall not be taxable to the holders of Common
     Stock for United States Federal income tax purposes.

                                       73
<PAGE>
 
          (5) In any case in which this Section 16.03 shall require that any
     adjustment be made effective as of or retroactively immediately following a
     record date, the Company may elect to defer (but only for five (5) Trading
     Days following the filing of the statement referred to in Section 16.05)
     issuing to the Holder of any Debt Securities converted after such record
     date the shares of Common Stock and other capital stock of the Company
     issuable upon such conversion over and above the shares of Common Stock and
     other capital stock of the Company issuable upon such conversion on the
     basis of the Conversion Price prior to adjustment; provided, however, that
     the Company shall deliver to such Holder a due bill or other appropriate
     instrument evidencing such Holder's right to receive such additional shares
     upon the occurrence of the event requiring such adjustment.

          (6) All calculations under this Section 16.03 shall be made to the
     nearest cent or one-hundredth of a share of security, with one-half cent
     and 0.005 of a share, respectively, being rounded upward.  Notwithstanding
     any other provision of this Section 16.03, the Company shall not be
     required to make any adjustment of the Conversion Price unless such
     adjustment would require an increase or decrease of at least 1% of such
     price.  Any lessor adjustment shall be carried forward and shall be made at
     the time of and together with the next subsequent adjustment which,
     together with any adjustment or adjustments so carried forward, shall
     amount to an increase or decrease of at least 1% in such price.  Any
     adjustments under this Section 16.03 shall be made successively whenever an
     event requiring such an adjustment occurs.

          (7) In the event that at any time, as a result of an adjustment made
     pursuant to this Section 16.03, the Holder of any Debt Security thereafter
     surrendered for conversion shall become entitled to receive any shares of
     stock of the Company other than shares of Common Stock into which the Debt
     Securities originally were convertible, the Conversion Price of such other
     shares so receivable upon conversion of any such Debt Security shall be
     subject to adjustment from time to time in a manner and on terms as nearly
     equivalent as practicable to the provisions with respect to Common Stock
     contained in subparagraphs (1) through (6) of this Section 16.03, and the
     provisions of Sections 16.01, 16.02 and 16.04 through 16.09 with respect to
     the Common Stock shall apply on like or similar terms to any such other
     shares and the determination of the Board of Directors as to any such
     adjustment shall be conclusive.

          (8) No adjustment shall be made pursuant to this Section:  (i) if the
     effect thereof would be to reduce the Conversion Price below the par value
     (if any) of the Common Stock or (ii)  subject to 16.03(5) hereof, with
     respect to any Debt Security that is converted prior to the time such
     adjustment otherwise would be made.

          Section 16.04.  Consolidation or Merger of the Company.
                          -------------------------------------- 

          In case of either (a) any consolidation or merger to which the Company
is a party, other than a merger or consolidation in which the Company is the
surviving or continuing corporation and which does not result in a
reclassification of, or change (other than a change in par value or from par
value to no par value or from no par value to par value, as a result of a
subdivision or combination) in, outstanding shares of Common Stock or (b) any
sale or conveyance of all or substantially all of the property and assets of the
Company to another Person, then each Debt Security then outstanding shall be
convertible from and after such merger, consolidation, sale or conveyance of
property and assets into the kind and amount of shares of stock or other
securities and property (including cash) receivable upon such consolidation,
merger, sale or conveyance by a holder of the number of shares of Common Stock
into which such Debt Securities would have been converted immediately prior to
such consolidation,

merger, sale or conveyance, subject to adjustments which shall be as nearly
equivalent as may be practicable to the adjustments provided for in this Article
Sixteen (and assuming such holder of Common Stock failed to exercise his rights
of election, if any, as to the kind or amount of securities, cash or other
property (including cash) receivable upon such consolidation, merger, sale or
conveyance (provided that, if the kind or amount of securities, cash or other
property (including cash) receivable upon such consolidation, merger, sale or
conveyance is not the same for each nonelecting share, then the kind and amount
of securities, cash or other property (including cash) receivable upon such
consolidation, merger, sale or conveyance for each nonelecting share shall be
deemed to be the kind and amount so receivable per share by a plurality of the
nonelecting shares or securities)).  The Company shall not enter into any of the
transactions referred to in clause (a) or (b) of the preceding sentence unless
effective provision shall be made so as to give effect to the provisions set
forth in this Section 16.04.  The provisions of this Section 16.04 shall apply
similarly to successive consolidations, mergers, sales or conveyances.

          Section 16.05.   Notice of Adjustment.
                           -------------------- 

          Whenever an adjustment in the Conversion Price with respect to a
series of Debt Securities is required:

          (1) the Company shall forthwith place on file with the Trustee and any
     Conversion Agent for such Securities a certificate of the Treasurer of the
     Company, stating the adjusted Conversion Price determined as provided
     herein and setting forth in reasonable detail such facts as shall be
     necessary to show the reason for and the manner of computing such
     adjustment, such certificate to be conclusive evidence that the adjustment
     is correct; and

          (2) a notice stating that the Conversion Price has been adjusted and
     setting forth the adjusted Conversion Price shall forthwith be given by the
     Company, or at the Company's request, by the Trustee in the name and at the
     expense of the Company, in the manner provided in Section 1.05.  Any notice
     so given shall be conclusively presumed to have been duly given, whether or
     not the Holder receives such notice.

          Section 16.06.  Notice in Certain Events.
                          ------------------------ 

          In case:
          ------- 

          (1) of a consolidation or merger to which the Company is a party and
     for which approval of any stockholders of the Company is required, or of
     the sale or conveyance to another Person or entity or group of Persons or
     entities acting in concert as a partnership, limited partnership, syndicate
     or other group (within the meaning of Rule 13d-3 under the Securities
     Exchange Act of 1934, as amended) of all or substantially all of the
     property and assets of the Company; or

          (2) of the voluntary or involuntary dissolution, liquidation or
     winding up of the Company; or

          (3) of any action triggering an adjustment of the Conversion Price
     pursuant to this Article Sixteen;

then, in each case, the Company shall cause to be filed with the Trustee and the
Conversion Agent for the applicable Debt Securities, and shall cause to be
given, to the Holders of record of applicable Debt

                                       75
<PAGE>
 
Securities in the manner provided in Section 1.05, at least fifteen (15) days
prior to the applicable date hereinafter specified, a notice stating (x) the
date on which a record is to be taken for the purpose of any distribution or
grant of rights or warrants triggering an adjustment to the Conversion Price
pursuant to this Article Sixteen, or, if a record is not to be taken, the date
as of which the holders of record or Common Stock entitled to such distribution,
rights or warrants are to be determined, or (y) the date on which any
reclassification, consolidation, merger, sale, conveyance, dissolution,
liquidation or winding up triggering an adjustment to the Conversion Price
pursuant to this Article Sixteen is expected to become effective, and the date
as of which it is expected that holders of Common Stock of record shall be
entitled to exchange their Common Stock for securities or other property
deliverable upon such reclassification, consolidation, merger, sale, conveyance,
dissolution, liquidation or winding up.

          Failure to give such notice or any defect therein shall not affect the
legality or validity of the proceedings described in clause (1), (2), or (3) of
this Section.

          Section 16.07.   Company to Reserve Stock; Registration; Listing.
                           ----------------------------------------------- 

          (a) The Company shall at all times reserve and keep available, free
from preemptive rights, out of its authorized but unissued shares of Common
Stock or Preferred Stock, as the case may be, for the purpose of effecting the
conversion of the Debt Securities, such number of its duly authorized shares of
Common Stock or Preferred Stock, as the case may be, as shall from time to time
be sufficient to effect the conversion of all applicable outstanding Debt
Securities into such Common Stock or Preferred Stock at any time (assuming that,
at the time of the computation of such number of shares or securities, all such
Debt Securities would be held by a single holder); provided, however, that
                                                   -----------------      
nothing contained herein shall preclude the Company from satisfying its
obligations in respect of the conversion of the Debt Securities by delivery of
purchased shares of Common Stock or Preferred Stock, as the case may be, which
are held in the treasury of the Company.  The Company shall from time to time,
in accordance with the laws of its state of incorporation, use its best efforts
to cause the authorized amount of the Common Stock or Preferred Stock, as the
case may be, to be increased if the aggregate of the authorized amount of the
Common Stock or Preferred Stock, as the case may be, remaining unissued and the
issued shares of such Common Stock or Preferred Stock in its treasury (other
than any such shares reserved for issuance in any other connection) shall not be
sufficient to permit the conversion of all Debt Securities.

          (b) If any shares of Common Stock or Preferred Stock, as the case may
be, which would be issuable upon conversion of Debt Securities hereunder require
registration with or approval of any governmental authority before such shares
or securities may be issued upon such conversion, the Company will in good faith
and as expeditiously as possible endeavor to cause such shares or securities to
be duly registered or approved, as the case may be.  The Company will endeavor
to list the shares of Common Stock or Preferred Stock required to be delivered
upon conversion of the Debt Securities prior to such delivery upon the principal
national securities exchange, if any, upon which the outstanding Common Stock or
Preferred Stock, as the case may be, is listed at the time of such delivery.

          Section 16.08.  Taxes on Conversion.
                          ------------------- 

          The Company shall pay any and all documentary, stamp or similar issue
or transfer taxes that may be payable in respect of the issue or delivery of
shares of Common Stock or Preferred Stock, as the case may be, on conversion of
Debt Securities pursuant hereto.  The Company shall not, however, be required to
pay any such tax which may be payable in respect of any transfer involved in the
issue or delivery of shares of Common Stock or Preferred Stock or the portion,
if any, of the Debt Securities

                                       76
<PAGE>
 
which are not so converted in a name other than that in which the Debt
Securities so converted were registered (in case of Registered Securities), and
no such issue or delivery shall be made unless and until the Person requesting
such issue has paid to the Company the amount of such tax or has established to
the satisfaction of the Company that such tax has been paid.

          Section 16.09.   Conversion After Record Date.
                           ---------------------------- 

          If any Debt Securities are surrendered for conversion subsequent to
the record date preceding an Interest Payment Date but on or prior to such
Interest Payment Date (except Debt Securities called for redemption on a
Redemption Date between such record date and Interest Payment Date), the Holder
of such Debt Securities at the close of business on such record date shall be
entitled to receive the interest payable on such Debt Securities on such
Interest Payment Date notwithstanding the conversion thereof.  Debt Securities
surrendered for conversion during the period from the close of business on any
record date next preceding any Interest Payment Date to the opening of business
on such Interest Payment Date to the opening of business on such Interest
Payment Date shall (except in the case of Debt Securities which have been called
for redemption on a Redemption Date within such period) be accompanied by
payment of an amount equal to the interest payable on such Interest Payment Date
on the Debt Securities being surrendered for conversion.  Except as provided in
this Section 16.09, no adjustments in respect of payments of interest on Debt
Securities surrendered for conversion or any dividends or distributions of
interest on the Common Stock issued upon conversion shall be made upon the
conversion of any Debt Securities.

          Section 16.10.   Company Determination Final.
                           --------------------------- 

          Any determination that the Company or the Board of Directors must make
pursuant to this Article is conclusive.

          Section 16.11.   Trustee's Disclaimer.
                           -------------------- 

          The Trustee has no duty to determine when an adjustment under this
Article should be made, how it should be made or what it should be.  The Trustee
makes no representation as to the validity or value of any securities or assets
issued upon conversion of Debt Securities.  The Trustee shall not be responsible
for the Company's failure to comply with this Article.  Each Conversion Agent
other than the Company shall have the same protection under this Section as the
Trustee.

          IN WITNESS WHEREOF, the parties hereto have caused this Indenture to
be duly executed, and their respective corporate seals to be hereunto affixed
and attested, all as of the day and year first above written.

     Unless otherwise specified pursuant to Section 3.01 or in any Debt
Security, in any case where any Interest Payment Date, Redemption Date or Stated
Maturity of any Debt Security of any series shall not be a Business Day at any
Place of Payment for the Debt Securities of that series, then (notwithstanding
any other provision of this Indenture or of the Debt Securities) payment of
principal of (and premium, if any) or interest on such Debt Securities of such
series need not be made at such Place of Payment on such date, but may be made
on the next succeeding Business Day at such Place of Payment with the same force
and effect as if made on the Interest Payment Date, Redemption Date or at the
Stated Maturity, and no interest shall accrue on the amount so payable for the
period from and after such Interest Payment Date, Redemption Date or Stated
Maturity, as the case may be, to such Business Day if such payment is made or
duly provided for on such Business Day.

of any securities exchange on which any series of the Debt Securities may be
listed, or to conform to usage, all as determined by the officers executing such
Debt Securities as conclusively evidenced by their execution of such Debt
Securities. If the form of a series of Debt Securities (or any Global Note) is
established in or pursuant to a Board Resolution, a copy of such Board

Note"), such Global Note may provide that it shall represent the aggregate
amount of Outstanding Debt Securities from time to time endorsed thereon and may
also provide that the aggregate amount of Outstanding Debt Securities
represented thereby may from time to time be reduced to reflect exchanges. Any
endorsement of a Global Note to reflect the amount, or any increase or decrease
in the amount, of Outstanding Debt Securities represented thereby shall be made
by the Trustee and in such manner as shall be specified in such Global Note. Any
instructions by the Company with respect to a Global Note, after its initial
issuance, shall be in writing but need not comply with Section 1.02.

     Global Notes may be issued in registered form and in either temporary or
permanent form. Permanent Global Notes will be issued in definitive form.

          (25)  any other terms of the series (which terms shall not be

          All Debt Securities of any one series shall be substantially identical
except as to denomination, rate of interest, Stated Maturity and the date from
which interest, if any, shall accrue, which, as set forth above, may be
determined by the Company from time to time as to Debt Securities of a series if

          Section 3.02.  Denominations.
                         ------------- 

          In the absence of any specification pursuant to Section 3.01 with
respect to the Debt Securities of any series, the Debt Securities of such series
shall be issuable only as Registered Securities in denominations of $1,000 and
any integral multiple thereof and shall be payable only in Dollars.

          Section 3.03.  Execution, Authentication, Delivery and Dating.
                         ---------------------------------------------- 

          The Debt Securities of any series shall be executed on behalf of the
Company by its Chairman, a Vice Chairman, its President, one of its Vice
Presidents or its Treasurer, under its corporate seal reproduced thereon and
attested by its Secretary or one of its Assistant Secretaries. The signature of
any of these officers may be manual or facsimile.

          Debt Securities bearing the manual or facsimile signatures of
individuals who were at any time the proper officers of the Company shall bind
the Company, notwithstanding that such individuals

                                       17
<PAGE>
 
or any of them have ceased to hold such offices prior to the authentication and
delivery of such Debt Securities or did not hold such offices at the date of
such Debt Securities.

          At any time and from time to time after the execution and delivery of
this Indenture, the Company may deliver Debt Securities of any series, executed
by the Company, to the Trustee for authentication, together with a Company Order
for the authentication and delivery of such Debt Securities and the Trustee in
accordance with the Company Order shall authenticate and deliver such Debt
Securities. If all the Debt Securities of any one series are not to be issued at
one time and if a Board Resolution or supplemental indenture relating to such
series shall so permit, such Company Order may set forth procedures acceptable
to the Trustee for the issuance of such Debt Securities such as interest rate,
Stated Maturity, date of issuance and date from which interest, if any, shall
accrue. If any Debt Security shall be represented by a permanent Global Note,
then, for purposes of this Section and Section 3.04, the notation of a
beneficial owner's interest therein upon original issuance of such Debt Security
or upon exchange of a portion of a temporary Global Note shall be deemed to be
delivery in connection with the original issuance of such beneficial owner's
interest in such permanent Global Note.

          The Trustee shall be entitled to receive, and (subject to Section
6.01) shall be fully protected in relying upon, prior to the authentication and
delivery of the Debt Securities of such series, (i) the supplemental indenture
or the Board Resolution by or pursuant to which the form and terms of such Debt
Securities have been approved and (ii) an Opinion of Counsel substantially to
the effect that:

          (1)  all instruments furnished by the Company to the Trustee in
     connection with the authentication and delivery of such Debt Securities
     conform to the requirements of this Indenture and constitute sufficient
     authority hereunder for the Trustee to authenticate and deliver such Debt
     Securities;

          (2)  the forms and terms of such Debt Securities have been established
     in conformity with the provisions of this Indenture;

          (3)  in the event that the forms or terms of such Debt Securities have
     been established in a supplemental indenture, the execution and delivery of
     such supplemental indenture has been duly authorized by all necessary
     corporate action of the Company, such supplemental  indenture has been duly
     executed and delivered by the Company and, assuming due authorization,
     execution and delivery by the Trustee, is a valid and binding obligation
     enforceable against the Company in accordance with its terms, subject to
     applicable bankruptcy, insolvency and similar laws affecting creditors'
     rights generally and subject, as to enforceability, to general principles
     of equity (regardless of whether enforcement is sought in a proceeding in
     equity or at law);

          (4)  the execution and delivery of such Debt Securities have been duly
     authorized by all necessary corporate action of the Company and such Debt
     Securities have been duly executed by the Company and, assuming due
     authentication by the Trustee and delivery by the Company, are valid and
     binding obligations enforceable against the Company in accordance with
     their terms, entitled to the benefit of the Indenture, subject to
     applicable bankruptcy, insolvency and similar laws affecting creditors'
     rights generally and subject, as to enforceability, to general principles
     of equity (regardless of whether enforcement is sought in a proceeding in
     equity or at law) and subject to such other exceptions as counsel shall
     request and as to which the Trustee shall not reasonably object; and

          (5)  the amount of Debt Securities Outstanding of such series,
     together with the amount of such Debt Securities, does not exceed any limit
     established under the terms of this

                                       18
<PAGE>
 
     Indenture on the amount of Debt Securities of such series that may be
     authenticated and delivered.

          The Trustee shall not be required to authenticate such Debt Securities
if the issuance of such Debt Securities pursuant to this Indenture will affect
the Trustee's own rights, duties or immunities under the Debt Securities and
this Indenture in a manner which is not reasonably acceptable to the Trustee.

          Each Registered Security shall be dated the date of its
authentication.

          No Debt Security shall be entitled to any benefit under this Indenture
or be valid or obligatory for any purpose unless there appears on such Debt
Security a certificate of authentication substantially in one of the forms
provided for herein duly executed by the Trustee or by an Authenticating Agent,
and such certificate upon any Debt Security shall be conclusive evidence, and
the only evidence, that such Debt Security has been duly authenticated and
delivered hereunder and is entitled to the benefits of this Indenture.
Notwithstanding the foregoing, if any Debt Security shall have been duly
authenticated and delivered hereunder but never issued and sold by the Company,
and the Company shall deliver such Debt Security to the Trustee for cancellation
as provided in Section 3.08 together with a written statement (which need not
comply with Section 1.02) stating that such Debt Security has never been issued
and sold by the Company, for all purposes of this Indenture such Debt Security
shall be deemed never to have been authenticated and delivered hereunder and
shall never be entitled to the benefits of this Indenture.

          Section 3.04.  Temporary Debt Securities; Global Notes Representing
                    ----------------------------------------------------
Registered Securities.
- --------------------- 

          (a) Pending the preparation of definitive Registered Securities of any
series, the Company may execute, and upon receipt by the Trustee of a Company
Order and satisfaction by the Company of the conditions precedent set forth
herein the Trustee shall authenticate and deliver, temporary Registered
Securities which are printed, lithographed, typewritten, mimeographed or
otherwise produced, in any authorized denomination for Registered Securities of
such series, substantially of the tenor of the definitive Registered Securities
in lieu of which they are issued and with such appropriate insertions,
omissions, substitutions and other variations as the officers executing such
Registered Securities may determine, as conclusively evidenced by their
execution of such Registered Securities. Every such temporary Registered
Security shall be executed by the Company and shall be authenticated and
delivered by the Trustee in accordance with Section 3.03 and upon the same
conditions and in substantially the same manner, and with the same effect, as
the definitive Registered Securities in lieu of which they are issued.

          Except in the case of temporary Debt Securities in global form (which
shall be exchanged in accordance with the provisions of the following
paragraphs), if temporary Debt Securities of any series are issued, the Company
will cause definitive Debt Securities of such series to be prepared without
unreasonable delay. After the preparation of definitive Debt Securities of such
series, the temporary Debt Securities of such series shall be exchangeable for
definitive Debt Securities of such series, of a like Stated Maturity and with
like terms and provisions, upon surrender of the temporary Debt Securities of
such series at the office or agency of the Company in a Place of Payment for
such series, without charge to the Holder, except as provided in Section 3.05 in
connection with a transfer. Upon surrender for cancellation of any one or more
temporary Debt Securities of any series, the Company shall execute and the
Trustee shall authenticate and deliver, in accordance with Section 3.03, in
exchange therefor a like principal amount of definitive Debt Securities of the
same series of authorized denominations and of a like Stated Maturity and like
terms and provisions. Until so exchanged, the temporary Registered

                                       19
<PAGE>
 
Securities of any series shall in all respects be entitled to the same benefits
under this Indenture as definitive Registered Securities of such series.

     (b)  If the Company shall establish pursuant to Section 3.01 that the
Registered Securities of a series are to be issued in whole or in part in the
form of one or more Global Notes, then the Company shall execute and the Trustee
shall, in accordance with Section 3.03 and the Company Order with respect to
such series, authenticate and deliver one or more Global Notes in temporary or
permanent form that (i) shall represent and shall be denominated in an amount
equal to the aggregate principal amount of the Outstanding Debt Securities of
such series to be represented by one or more Global Notes, (ii) shall be
registered in the name of the U.S. Depositary for such Global Note or Notes or
the nominee of such depositary, and (iii) shall bear a legend substantially to
the following effect: "This Debt Security may not be transferred except as a
whole by the Depositary to a nominee of the Depositary or by a nominee of the
Depositary to the Depositary or another nominee of the Depositary or by the
Depositary or any such nominee to a successor Depositary or a nominee of such
successor Depositary, unless and until this Debt Security is exchanged in whole
or in part for Debt Securities in definitive form."

     Notwithstanding any other provision of this Section or Section 3.05, unless
and until it is exchanged in whole or in part for Registered Securities in
definitive form, a Global Note representing all or a portion of the Registered
Securities of a series may not be transferred except as a whole by the U.S.
Depositary for such series to a nominee of such depositary or by a nominee of
such depositary to such depositary or another nominee of such depositary or by
such depositary or any such nominee to a successor U.S. Depositary for such
series or a nominee of such successor depositary.

     If at any time the U.S. Depositary for the Debt Securities of a series
notifies the Company that it is unwilling or unable to continue as U.S.
Depositary for the Debt Securities of such series or if at any time the U.S.
Depositary for Debt Securities of a series shall no longer be a clearing agency
registered and in good standing under the Securities Exchange Act of 1934, as
amended, or other applicable statute or regulation, the Company shall appoint a
successor U.S. Depositary with respect to the Debt Securities of such series. If
a successor U.S. Depositary for the Debt Securities of such series is not
appointed by the Company within 90 days after the Company receives such notice
or becomes aware of such condition, the Company will execute, and the Trustee,
upon receipt of a Company Order for the authentication and delivery of
definitive Debt Securities of such series, will authenticate and deliver,
Registered Securities of such series in definitive form in an aggregate
principal amount equal to the principal amount of the Global Note or Notes
representing such series in exchange for such Global Note or Notes.

     The Company may at any time and in its sole discretion determine that the
Registered Securities of any series issued in the form of one or more Global
Notes shall no longer be represented by such Global Note or Notes. In such
event, the Company will execute, and the Trustee, upon receipt of a Company
Order for the authentication and delivery of definitive Debt Securities of such
series, will in accordance with Section 3.03 authenticate and deliver,
Registered Securities of such series in definitive form and in an aggregate
principal amount equal to the principal amount of the Global Note or Notes
representing such series in exchange for such Global Note or Notes.

     If the Registered Securities of any series shall have been issued in the
form of one or more Global Notes and if an Event of Default with respect to the
Debt Securities of such series shall have occurred and be continuing, the
Company will promptly execute, and the Trustee, upon receipt of a Company Order
for the authentication and delivery of definitive Debt Securities of such
series, will in accordance with Section 3.03 authenticate and deliver,
Registered Securities of such series in definitive

                                       20
<PAGE>
 
form and in an aggregate principal amount equal to the principal amount of the
Global Note or Notes representing such series in exchange for such Global Note
or Notes.

     If specified by the Company pursuant to Section 3.01 with respect to
Registered Securities of a series, the U.S. Depositary for such series of
Registered Securities may surrender a Global Note for such series of Debt
Securities in exchange in whole or in part for Registered Securities of such
series in definitive form on such terms as are acceptable to the Company and
such depositary. Thereupon, the Company shall execute and the Trustee shall in
accordance with Section 3.03 authenticate and deliver, without charge:

          (i)  to each Person specified by the U.S. Depositary a new Registered
     Security or Securities of the same series, of any authorized denomination
     as requested by such Person in an aggregate principal amount equal to and
     in exchange for such Person's beneficial interest in the Global Note; and

          (ii)  to the U.S. Depositary a new Global Note in a denomination equal
     to the difference, if any, between the principal amount of the surrendered
     Global Note and the aggregate principal amount of Registered Securities
     delivered to Holders thereof.

     Upon the exchange of a Global Note for Registered Securities in definitive
form, such Global Note shall be cancelled by the Trustee. Debt Securities issued
in exchange for a Global Note pursuant to this subsection (c) shall be
registered in such names and in such authorized denominations as the U.S.
Depositary for such Global Note, pursuant to instructions from its direct or
indirect participants or otherwise, shall instruct the Trustee. The Trustee
shall deliver such Debt Securities to the Persons in whose names such Debt
Securities are so registered.

     Section 3.05.  Registration, Transfer and Exchange.
                    ----------------------------------- 

     (a)  The Company shall cause to be kept at the Corporate Trust Office of
the Trustee a register (the registers maintained in such office and in any other
office or agency of the Company in a Place of Payment being herein sometimes
collectively referred to as the "Security Register") in which, subject to such
reasonable regulations as it may prescribe, the Company shall provide for the
registration of Registered Securities and of transfers and exchanges of
Registered Securities. The Trustee is hereby appointed "Security Registrar" for
the purpose of registering Registered Securities and registering transfers and
exchanges of Registered Securities as herein provided; provided, however, that
                                                       --------  -------      
the Company may appoint co-Security Registrars or the terms of any series of
Debt Securities may provide otherwise.

     Upon surrender for registration of transfer of any Registered Security of
any series at the office or agency of the Company maintained for such purpose,
the Company shall execute, and the Trustee shall authenticate and deliver, in
the name of the designated transferee, one or more new Registered Securities of
the same series of like aggregate principal amount of such denominations as are
authorized for Registered Securities of such series and of a like Stated
Maturity and with like terms and conditions.

     Except as otherwise provided in Section 3.04 and this Section 3.05, at the
option of the Holder, Registered Securities of any series may be exchanged for
other Registered Securities of the same series of like aggregate principal
amount and of a like Stated Maturity and with like terms and conditions, upon
surrender of the Registered Securities to be exchanged at such office or agency.
Whenever any Registered Securities are surrendered for exchange, the Company
shall execute, and the Trustee shall

                                       21
<PAGE>
 
authenticate and deliver in accordance with Section 3.03, the Registered
Securities which the Holder making the exchange is entitled to receive.

     (b)  All Debt Securities issued upon any transfer or exchange of Debt
Securities shall be valid obligations of the Company, evidencing the same debt,
and entitled to the same benefits under this Indenture, as the Debt Securities
surrendered for such transfer or exchange.

     Every Registered Security presented or surrendered for transfer or exchange
shall (if so required by the Company or the Trustee) be duly endorsed, or be
accompanied by a written instrument of transfer in form satisfactory to the
Company and the Security Registrar, duly executed, by the Holder thereof or his
attorney duly authorized in writing.

     No service charge will be made for any transfer or exchange of Debt
Securities except as provided in Section 3.06. The Company may require payment
of a sum sufficient to cover any tax or other governmental charge that may be
imposed in connection with any registration, transfer or exchange of Debt
Securities, other than those expressly provided in this Indenture to be made at
the Company's own expense or without expense or without charge to the Holders.

     The Company shall not be required (i) to register, transfer or exchange
Debt Securities of any series during a period beginning at the opening of
business 15 days before the day of the transmission of a notice of redemption of
Debt Securities of such series selected for redemption under Section 13.03 and
ending at the close of business on the day of such transmission, or (ii) to
register, transfer or exchange any Debt Security so selected for redemption in
whole or in part, except the unredeemed portion of any Debt Security being
redeemed in part.

     Section 3.06.  Mutilated, Destroyed, Lost and Stolen Debt Securities.
                    ----------------------------------------------------- 

     If (i) any mutilated Debt Security is surrendered to the Trustee at its
Corporate Trust Office or (ii) the Company and the Trustee receive evidence to
their satisfaction of the destruction, loss or theft of any Debt Security and
there is delivered to the Company and the Trustee such security or indemnity as
may be required by them to save each of them and any Paying Agent harmless, and
neither the Company nor the Trustee receives actual notice that such Debt
Security has been acquired by a bona fide purchaser, then the Company shall
execute and upon Company Request the Trustee shall authenticate and deliver, in
exchange for or in lieu of any such mutilated, destroyed, lost or stolen Debt
Security, a new Debt Security of the same series of like Stated Maturity and
with like terms and conditions and like principal amount, bearing a number not
contemporaneously Outstanding, and that neither gain nor loss in interest shall
result from such exchange or substitution.

     In case any such mutilated, destroyed, lost or stolen Debt Security has
become or is about to become due and payable, the Company in its discretion may,
instead of issuing a new Debt Security, pay the amount due on such Debt Security
in accordance with its terms;

     Upon the issuance of any new Debt Security under this Section, the Company
may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in respect thereto and any other
expenses (including the fees and expenses of the Trustee) connected therewith.

     Every new Debt Security of any series issued pursuant to this Section shall
constitute an original additional contractual obligation of the Company, whether
or not the destroyed, lost or stolen Debt Security shall be at any time
enforceable by anyone, and shall be entitled to all the benefits of this

                                       22
<PAGE>
 
Indenture equally and proportionately with any and all other Debt Securities of
that series duly issued hereunder.

     The provisions of this Section are exclusive and shall preclude (to the
extent lawful) all other rights and remedies with respect to the replacement or
payment of mutilated, destroyed, lost or stolen Debt Securities.

     Section 3.07.  Payment of Interest; Interest Rights Preserved.
                    ---------------------------------------------- 

     (a)  Interest on any Registered Security which is payable and is punctually
paid or duly provided for on any Interest Payment Date shall be paid to the
Person in whose name such Registered Security (or one or more Predecessor
Securities) is registered at the close of business on the Regular Record Date
for such interest notwithstanding the cancellation of such Registered Security
upon any transfer or exchange subsequent to the Regular Record Date. Unless
otherwise specified as contemplated by Section 3.01 with respect to the Debt
Securities of any series, payment of interest on Registered Securities shall be
made at the place or places specified pursuant to Section 3.01 or, at the option
of the Company, by check mailed to the address of the Person entitled thereto as
such address shall appear in the Security Register or, if provided pursuant to
Section 3.01, by wire transfer to an account designated by the Registered
Holder.
     
     (b)  Any interest on any Debt Security which is payable but is not
punctually paid or duly provided for on any Interest Payment Date (herein called
"Defaulted Interest") shall, if such Debt Security is a Registered Security,
forthwith cease to be payable to the Registered Holder on the relevant Regular
Record Date by virtue of his having been such Registered Holder, and such
Defaulted Interest may be paid by the Company, at its election in each case, as
provided in clause (1) or (2) below:

          (1)  The Company may elect to make payment of any Defaulted Interest
     to the Persons in whose names such Registered Securities (or their
     respective Predecessor Securities) are registered at the close of business
     on a Special Record Date for the payment of such Defaulted Interest, which
     shall be fixed in the following manner. The Company shall notify the
     Trustee in writing of the amount of Defaulted Interest proposed to be paid
     on each such Registered Security and the date of the proposed payment, and
     at the same time the Company shall deposit with the Trustee an amount of
     money equal to the aggregate amount proposed to be paid in respect of such
     Defaulted Interest or shall make arrangements satisfactory to the Trustee
     for such deposit prior to the date of the proposed payment, such money when
     deposited to be held in trust for the benefit of the Persons entitled to
     such Defaulted Interest as in this clause provided. Thereupon the Trustee
     shall fix a Special Record Date for the payment of such Defaulted Interest
     which date shall be not more than 15 days and not less than 10 days prior
     to the date of the proposed payment and not less than 10 days after the
     receipt by the Trustee of the notice of the proposed payment. The Trustee
     shall promptly notify the Company of such Special Record Date and, in the
     name and at the expense of the Company, shall cause notice of the proposed
     payment of such Defaulted Interest and the Special Record Date therefor to
     be mailed, first-class postage prepaid, to the Holders of such Registered
     Securities at their addresses as they appear in the Security Register, not
     less than 10 days prior to such Special Record Date. Notice of the proposed
     payment of such Defaulted Interest and the Special Record Date therefor
     having been mailed as aforesaid, such Defaulted Interest shall be paid to
     the Persons in whose names such Registered Securities (or their respective
     Predecessor Securities) are registered at the close of business on such
     Special Record Date and shall no longer be payable pursuant to the
     following clause (2).

                                       23
<PAGE>
 
          (2)  The Company may make payment of any Defaulted Interest on
     Registered Securities in any other lawful manner not inconsistent with the
     requirements of any securities exchange on which such Registered Securities
     may be listed, and upon such notice as may be required by such exchange,
     if, after notice given by the Company to the Trustee of the proposed
     payment pursuant to this clause, such manner of payment shall be deemed
     practicable by the Trustee.

     (c)  Subject to the foregoing provisions of this Section, each Debt
Security delivered under this Indenture upon transfer of or in exchange for or
in lieu of any other Debt Security shall carry the rights to interest accrued
and unpaid, and to accrue, which were carried by such other Debt Security.

     Section 3.08.  Cancellation.
                    ------------ 

     Unless otherwise specified pursuant to Section 3.01 for Debt Securities of
any series, all Debt Securities surrendered for payment, redemption, transfer,
exchange or credit against any sinking fund shall, if surrendered to any Person
other than the Trustee, be delivered to the Trustee. All Registered Securities
so delivered shall be promptly cancelled by the Trustee. The Company may at any
time deliver to the Trustee for cancellation any Debt Securities previously
authenticated and delivered hereunder which the Company may have acquired in any
manner whatsoever, and may deliver to the Trustee (or to any other Person for
delivery to the Trustee) for cancellation any Debt Securities previously
authenticated hereunder which the Company has not issued, and all Debt
Securities so delivered shall be promptly cancelled by the Trustee. No Debt
Securities shall be authenticated in lieu of or in exchange for any Debt
Securities cancelled as provided in this Section, except as expressly permitted
by this Indenture. All cancelled Debt Securities held by the Trustee shall be
delivered to the Company upon Company Request. The acquisition of any Debt
Securities by the Company shall not operate as a redemption or satisfaction of
the indebtedness represented thereby unless and until such Debt Securities are
surrendered to the Trustee for cancellation. Permanent Global Notes shall not be
destroyed until exchanged in full for definitive Debt Securities or until
payment thereon is made in full.

     Section 3.09.  Computation of Interest.
                    ----------------------- 

     Except as otherwise specified pursuant to Section 3.01 for Debt Securities
of any series, interest on the Debt Securities of each series shall be computed
on the basis of a 360-day year of twelve 30-day months.

     Section 3.10.  Judgments.
                    --------- 

     The Company agrees, to the fullest extent that it may effectively do so
under applicable law, that (a) if for the purpose of obtaining judgment in any
court it is necessary to convert the sum due in respect of the principal of, or
premium or interest, if any, on the Debt Securities of any series (the "Required
Currency") into a currency in which a judgment will be rendered (the "Judgment
Currency"), the rate of exchange used shall be the rate at which in accordance
with normal banking procedures the Trustee could purchase in the City of New
York the Required Currency with the Judgment Currency on the New York Banking
Day (as defined below) preceding that on which final unappealable judgment is
given and (b) its obligations under this Indenture to make payments in the
Required Currency (i) shall not be discharged or satisfied by any tender, or any
recovery pursuant to any judgment (whether or not entered in accordance with
subsection (a)), in any currency other than the Required Currency, except to the
extent that such tender or recovery shall result in the actual receipt, by the
payee, of the full amount of the Required Currency expressed to be payable in
respect of such payments, (ii) shall be enforceable as an alternative or
additional cause of action for the purpose of recovering in the Required
Currency the

                                       24
<PAGE>
 
amount, if any, by which such actual receipt shall fall short of the full amount
of the Required Currency so expressed to be payable and (iii) shall not be
affected by judgment being obtained for any other sum due under this Indenture.
For purposes of the foregoing,"New York Banking Day" means any day except a
Saturday, Sunday or a legal holiday in the City of New York or a day on which
banking institutions in the City of New York are authorized or required by law
or executive order to close.

     Section 3.11.  Exchange Upon Default.
                    --------------------- 

     If default is made in the payments referred to in Section 12.01, the
Company hereby undertakes that upon presentation and surrender of a permanent
Global Note to the Trustee (or to any other Person or at any other address as
the Company may designate in writing), on any Business Day on or after the
maturity date thereof the Company will issue and the Trustee will authenticate
and deliver to the bearer of such permanent Global Note duly executed and
authenticated definitive Debt Securities with the same issue date and maturity
date as set out in such permanent Global Note.

                    --------------------------------------- 

     This Indenture, with respect to the Debt Securities of any series (if all
series issued under this Indenture are not to be affected), shall, upon Company
Request, cease to be of further effect (except as to any surviving rights of
registration of transfer or exchange of such Debt Securities herein expressly
provided for and rights to receive payments of principal (and premium, if any)
and interest on such Debt Securities) and the Trustee, at the expense of the
Company, shall execute proper instruments acknowledging satisfaction and

          (A)  all Debt Securities of such series theretofore authenticated and

     in Section 3.06, and (ii) Debt Securities of such series for whose payment
     money has theretofore been deposited in trust or segregated and held in

               (iii)  are to be called for redemption within one year under
                      arrangements satisfactory to the Trustee for the giving of

                      the Company,

     and the Company, either complies with any other condition or terms
     specified pursuant to Section 3.01, or if not so specified in the case of
     (i), (ii) or (iii) of this subclause (B), has irrevocably deposited or
     caused to be deposited with the Trustee as trust funds in trust for such
     purpose an amount sufficient to pay and discharge the entire indebtedness
     on such Debt Securities for principal (and premium, if any) and interest to
     the date of such deposit (in the case of Debt Securities which have become
     due and payable) or to the Stated Maturity or Redemption Date, as the case
     may be; provided, however, in the event a petition for relief under the

     applicable Federal or state bankruptcy, insolvency or other similar law,
     is filed with respect to the Company within 91 days after the deposit and
     the Trustee is required to return the deposited money to the Company, the
     obligations of the Company under this Indenture with respect to such Debt
     Securities shall not be deemed terminated or discharged;

          (2)  the Company has paid or caused to be paid all other sums payable
     hereunder by the Company;

          (3)  the Company has delivered to the Trustee an Officers' Certificate
     and an Opinion of Counsel each stating that all conditions precedent herein
     provided for relating to the satisfaction and discharge of this Indenture
     with respect to such series have been complied with; and

          (4)  the Company has delivered to the Trustee an Opinion of Counsel or
     a ruling by the Internal Revenue Service to the effect that Holders of the

applied by it, in accordance with the provisions of the Debt Securities and this
Indenture, to the payment, either directly or through any Paying Agent
(including the Company acting as its own Paying Agent) as the Trustee may
determine, to the Persons entitled thereto, of the principal (and premium, if
any) and interest for whose payment such money has been deposited with the
Trustee.

          Section 5.02. Acceleration of Maturity; Rescission and Annulment.
                        -------------------------------------------------- 

          If an Event of Default with respect to Debt Securities of any series
at the time Outstanding occurs and is continuing, then in every such case the
Trustee or the Holders of not less than

                                       27
<PAGE>
 
25% in principal amount of the Outstanding Debt Securities of such series may
declare the principal amount (or, if any Debt Securities of such series are
Discount Securities, such portion of the principal amount of such Discount
Securities as may be specified in the terms of such Discount Securities) of all
the Debt Securities of such series to be due and payable immediately, by a
notice in writing to the Company (and to the Trustee if given by Holders), and
upon any such declaration such principal amount (or specified amount) plus
accrued and unpaid interest (and premium, if payable) shall become immediately
due and payable.  Upon payment of such amount, all obligations of the Company in
respect of the payment of principal of the Debt Securities of such series shall
terminate.

          At any time after such a declaration of acceleration with respect to
Debt Securities of any series has been made and before a judgment or decree for
payment of the money due has been obtained by the Trustee as hereinafter in this
Article provided, the Holders of a majority in principal amount of the
Outstanding Debt Securities of such series, by written notice to the Company and
the Trustee, may rescind and annul such declaration and its consequences if

          (1) the Company has paid or deposited with the Trustee a sum
     sufficient to pay

          (A) all overdue installments of interest on all Debt Securities,

          (B) the principal of (and premium, if any, on) any Debt Securities of
          such series which have become due otherwise than by such declaration

Trustee.
- ------- 

          The Company covenants that if

          (1) default is made in the payment of any installment of interest on
     any Debt Security when such interest or payment becomes due and payable and
     such default continues for a period of 30 days,

          (2) default is made in the payment of principal of (or premium, if
     any, on) any Debt Security at the Maturity thereof, or

                                       28
<PAGE>
 
          (3) default is made in the making or satisfaction of any sinking fund
     payment or analogous obligation when the same becomes due pursuant to the
     terms of the Debt Securities of any series,

the Company will, upon demand of the Trustee, pay to it, for the benefit of the
Holders of such Debt Securities, the amount then due and payable on such Debt
Securities for the principal (and premium, if any) and interest, if any, and, to
the extent that payment of such interest shall be legally enforceable, interest
upon the overdue principal (and premium, if any) and upon overdue installments
of interest, at the Overdue Rate; and, in addition thereto, 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.

          If the Company fails to pay such amount forthwith upon such demand,
the Trustee, in its own name and as trustee of an express trust, may institute a
judicial proceeding for the collection of the sums so due and unpaid, and may
prosecute such proceeding to judgment or final decree, and may enforce the same
against the Company or any other obligor upon such Debt Securities and collect
the moneys adjudged or decreed to be payable in the manner provided by law out
of the property of the Company or any other obligor upon such Debt Securities
wherever situated.

          If an Event of Default with respect to Debt Securities of any series
occurs and is continuing, the Trustee may in its discretion proceed to protect
and enforce its rights and the rights of the Holders of Debt Securities of such
series by such appropriate judicial proceedings as the Trustee shall deem most
effectual to protect and enforce any such rights, whether for the specific
enforcement of any covenant or agreement in this Indenture or in aid of the
exercise of any power granted herein, or to enforce any other proper remedy.

bankruptcy, reorganization, arrangement, adjustment, composition or other
judicial proceedings, or any voluntary or involuntary case under the Federal
bankruptcy laws, as now or hereafter constituted, relative to the Company or any
other obligor upon the Debt Securities of a particular series or the property of
the Company or of such other obligor or their creditors, the Trustee
(irrespective of whether the principal of such Debt Securities shall then be due
and payable as therein expressed or by declaration of acceleration or otherwise
and irrespective of whether the Trustee shall have made any demand on the
Company for the payment of overdue principal or interest) shall be entitled and
empowered, by intervention in such proceeding or otherwise,

          (i) to file and prove a claim for the whole amount of principal (or,
     if the Debt Securities of such series are Discount Securities, such portion
     of the principal amount as may be due and payable with respect to such
     series pursuant to a declaration in accordance with Section 5.02) (and
     premium, if any) and interest owing and unpaid in respect of the Debt
     Securities of such series and to file such 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 of
     the Holders of such Debt Securities allowed in such judicial proceeding,
     and

          (ii) to collect and receive any moneys or other property payable or
     deliverable on any such claims and to distribute the same;

                                       29

and any receiver, assignee, trustee, custodian, liquidator, sequestrator (or
other similar official) in any such proceeding is hereby authorized by each such
Holder to make such payments to the Trustee, and in the event that the Trustee
shall consent to the making of such payments directly to such Holders, to pay to
the Trustee any amount due 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 6.07.

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

     6.07.

          SECOND: To the payment of the amounts then due and unpaid for
     principal of (and premium, if any) and interest on the Debt Securities of
     such series, in respect of which or for the benefit of which such money has

     in its own name as Trustee hereunder;

          (3) such Holder or Holders have offered to the Trustee reasonable
     indemnity against the costs, expenses and liabilities to be incurred in
     compliance with such request;

          (4) the Trustee for 60 days after its receipt of such notice, request
     and offer of indemnity has failed to institute any such proceeding; and

          (5) no direction inconsistent with such written request has been given
     to the Trustee during such 60-day period by the Holders of a majority in
     principal amount of the Outstanding Debt Securities of such series;

it being understood and intended that no one or more of such Holders shall have
any right in any manner whatever by virtue of, or by availing of, any provision
of this Indenture to affect, disturb or prejudice the rights of any other such
Holders or of the Holders of Outstanding Debt Securities of any other series, or
to obtain or to seek to obtain priority or preference over any other of such
Holders or to enforce any right under this Indenture, except in the manner
herein provided and for the equal and ratable benefit of all of such Holders.

Holders is intended to be exclusive of any other right or remedy, and every
right and remedy shall, to the extent permitted by law, be cumulative and in

right or remedy hereunder, or otherwise, shall not prevent the concurrent
assertion or employment of any other appropriate right or remedy.

          No delay or omission of the Trustee or of any Holder to exercise any
right or remedy accruing upon any Event of Default shall impair any such right
or remedy or constitute a waiver of any such Event of Default or any
acquiescence therein.  Every right and remedy given by this Indenture or by law
to the Trustee or to the Holders may be exercised from time to time, and as
often as may be deemed expedient, by the Trustee or by the Holders, as the case

Securities of any series shall have the right to direct the time, method and
place of conducting any proceeding for any remedy available to the Trustee or
exercising any trust or power conferred on the Trustee with respect to the Debt
Securities of such series, provided, that

          (1) such direction shall not be in conflict with any rule of law or
     with this Indenture;

          (2) subject to the provisions of Section 6.01, the Trustee shall have
     the right to decline to follow any such direction if the Trustee in good
     faith shall, by a Responsible Officer or Responsible Officers of the
     Trustee, determine that the proceeding so directed would be unjustly
     prejudicial to the Holders of Debt Securities of such series not joining in
     any such direction; and

          (3) the Trustee may take any other action deemed proper by the Trustee
     which is not inconsistent with such direction.

all the Debt Securities of any such series waive any past default hereunder with
respect to such series and its consequences, except a default

          (1) in the payment of the principal of (or premium, if any) or
     interest on any Debt Security of such series, or in the payment of any
     sinking fund installment or analogous obligation with respect to the Debt
     Securities of such series, or

          (2) in respect of a covenant or provision hereof which pursuant to
     Article Eleven cannot be modified or amended without the consent of the
     Holder of each Outstanding Debt Security of such series affected.

          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 the Debt Securities of such series under this Indenture, but no such
waiver shall extend to any subsequent or other default or impair any right
consequent thereon.

action taken, suffered or omitted by it as Trustee, the filing by any party
litigant in such suit other than the Trustee of an undertaking to pay the costs
of such suit, and that such court may in its discretion assess reasonable costs,
including reasonable attorneys' fees, against any party litigant in such suit,
having due regard to the merits and good faith of the claims or defenses made by
such party litigant, but the provisions of this Section shall not apply to any
suit instituted by the Trustee, to any suit instituted by any Holder or group of
Holders holding in the aggregate more than 10% in principal amount of the
Outstanding Debt Securities of any series, or to any suit instituted by any
Holder of a Debt Security for the enforcement of the payment of the principal of
(or premium, if any) or interest on such Debt Security on or after the
respective Stated Maturity or Maturities expressed in such Debt Security (or, in
the case of redemption, on or after the Redemption Date).

                        -------------------------------- 

          The Company covenants (to the extent that it may lawfully do so) that
it will not at any time insist upon, or plead, or in any manner whatsoever claim
or take the benefit or advantage of, any stay or extension law wherever enacted,
now or at any time hereafter in force, which 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 will not hinder, delay or impede the execution of any
power herein granted to the Trustee, but will suffer and permit the execution of
every such power as though no such law had been enacted.

     as are specifically set forth in this Indenture, and no implied covenants
     or obligations shall be read into this Indenture against the Trustee; and

          (2) in the absence of bad faith on its part, the Trustee may
     conclusively rely, as to the truth of the statements and the correctness of
     the opinions expressed therein, upon certificates or opinions furnished to
     the Trustee and conforming to the requirements of this Indenture; but in
     the case of any such certificates or opinions which by any provisions
     hereof are specifically required to be furnished to the Trustee, the
     Trustee shall be under a duty to examine the same to determine whether or
     not they conform to the requirements of this Indenture.

series has occurred and is continuing, the Trustee shall, with respect to the
Debt Securities of such series, exercise such of the rights and powers vested in
it by this Indenture, and 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.

          (c) No provision of this Indenture shall be construed to relieve the
Trustee from liability for its own negligent action, its own negligent failure

     subsection (a) of this Section;

     good faith by a Responsible Officer, unless it shall be proved that the
     Trustee was negligent in ascertaining the pertinent facts;

          (3) the Trustee shall not be liable with respect to any action taken,
     suffered or omitted to be taken by it with respect to Debt Securities of

     a majority in principal amount of the Outstanding Debt Securities of such

     conferred upon the Trustee, under this Indenture; and

     or otherwise incur any financial liability in the performance of any of its
     duties hereunder, or in the exercise of any of its rights or powers, if it
     shall have reasonable grounds for believing that repayment of such funds or
     adequate indemnity against such risk or liability is not reasonably assured
     to it.

          (d) Whether or not therein expressly so provided, every provision of
this Indenture relating to the conduct or affecting the liability of or
affording protection to the Trustee shall be subject to the provisions of this

     trustee upon its request for all reasonable expenses, disbursements and
     advances incurred or made by the Trustee in accordance with any provision
     of this Indenture (including the reasonable compensation and the expenses
     and disbursements of its agents and counsel), except any such expense,
     disbursement or advance as may be attributable to its negligence or bad
     faith; and

          (3) to indemnify the Trustee for, and to hold it harmless against, any
     loss, liability or expense incurred without negligence or bad faith on its
     part, arising out of or in connection with the acceptance or administration
     of this trust or performance of its duties hereunder, including the costs
     and expenses of defending itself against any claim or liability in
     connection with the exercise or performance of any of its powers or duties
     hereunder.

          As security for the performance of the obligations of the Company
under this Section, the Trustee shall have a claim prior to the Debt Securities
upon all property and funds held or collected by the Trustee as such, except
funds held in trust for the payment of amounts due on the Debt Securities.

          The obligations of the Company under this Section 6.07 to compensate
and indemnify the Trustee for expenses, disbursements and advances shall
constitute additional indebtedness under this Indenture and shall survive the
satisfaction and discharge of this Indenture.

           Section 6.08.  Disqualification; Conflicting Interests.
                          --------------------------------------- 

          (a) If the Trustee has or shall acquire any conflicting interest, as
defined in this Section with respect to the Debt Securities of any series, then,
within 90 days after ascertaining that it has such conflicting interest, and if
the default (as hereinafter defined) to which such conflicting interest relates
has not been cured or duly waived or otherwise eliminated before the end of such
90-day period, the Trustee shall either eliminate such conflicting interest or,
except as otherwise provided below, resign with respect to the Debt Securities
of such series, and the Company shall take prompt steps to have a successor
appointed, in the manner and with the effect hereinafter specified in this
Article.

          (b) In the event that the Trustee shall fail to comply with the
provisions of subsection (a) of this Section with respect to the Debt Securities
of any series, the Trustee shall, within 10 days after the expiration of such
90-day period, transmit to all Holders of Debt Securities of such series notice
of such failure.

          Notice given pursuant to this Section 6.08(b) shall be transmitted by
mail:

          (1) to all Registered Holders, as the names and addresses of the
     Registered Holders appear in the Security Register; and

          (2) to each Holder of a Debt Security of any series whose name and
     address appear in the information preserved at the time by the Trustee in
     accordance with Section 7.02(a) of this Indenture.

          (c) For the purposes of this Section, the Trustee shall be deemed to
have a conflicting interest with respect to the Debt Securities of any series,
if there shall exist an Event of Default (as such term is defined herein, but
exclusive of any period of grace or requirement of notice) with respect to such
Debt Securities and

          (1) the Trustee is trustee under this Indenture with respect to the
     Outstanding Debt Securities of any series other than that series or is
     trustee under another indenture under which any other securities, or
     certificates of interest or participation in any other securities, of the
     Company are outstanding, unless such other indenture is a collateral trust
     indenture under which the only collateral consists of Debt Securities
     issued under this Indenture, provided that there shall be excluded from the
     operation of this paragraph of this Indenture with respect to the Debt
     Securities of any series other than that series and any other indenture or
     indentures under which other securities, or certificates of interest or
     participation in other securities, of the Company are outstanding, if

               (i) this Indenture and such other indenture or indentures (and
          all series of securities issuable thereunder) are wholly unsecured and
          rank equally and such other indenture or indentures are hereafter
          qualified under the Trust Indenture Act, unless the Commission shall
          have found and declared by order pursuant to Section 305(b) or Section
          307(c) of the Trust Indenture Act that differences exist between the
          provisions of this Indenture with respect to the Debt Securities of
          such series and one or more other series or the provisions of such
          other indenture or indentures which are so likely to involve a
          material conflict of interest as to make it necessary, in the public
          interest or for the protection of investors to disqualify the Trustee
          from acting as such under this Indenture with respect to the Debt
          Securities of such series and such other series or under such other
          indenture or indentures, or

<PAGE>
 
              (ii)  the Company shall have sustained the burden of proving, on
          application to the Commission and after opportunity for hearing
          thereon, that trusteeship under this Indenture with respect to the
          Debt Securities of such series and such other series or such other
          indenture or indentures is not so likely to involve a material
          conflict of interest as to make it necessary in the public interest or
          for the protection of investors to disqualify the Trustee from acting
          as such under this Indenture with respect to the Debt Securities of
          such series and such other series or under such other indenture or
          indentures;

          (2) the Trustee or any of its directors or executive officers is an
     underwriter for the Company;

          (3) the Trustee directly or indirectly controls or is directly or
     indirectly controlled by or is under direct or indirect common control with
     an underwriter for the Company;

          (4) the Trustee or any of its directors or executive officers is a
     director, officer, partner, employee, appointee or representative of the
     Company, or of an underwriter (other than the Trustee itself) for the
     Company who is currently engaged in the business of underwriting, except
     that (i) one individual may be a director or an executive officer, or both,
     of the Trustee and a director or an executive officer, or both, of the
     Company but may not be at the same time an executive officer of both the
     Trustee and the Company; (ii) if and so long as the number of directors of
     the Trustee in office is more than nine, one additional individual may be a
     director or an executive officer, or both, of the Trustee and a director of
     the Company; and (iii) the Trustee may be designated by the Company or by
     any underwriter for the Company to act in the capacity of transfer agent,
     registrar, custodian, paying agent, fiscal agent, escrow agent, or
     depositary or in any other similar capacity, or, subject to the provisions
     of paragraph (c) of this subsection, to act as trustee, whether under an
     indenture or otherwise;

          (5) 10% or more of the voting securities of the Trustee is
     beneficially owned either by the Company or by any director, partner or
     executive officer thereof, or 20% or more of such voting securities is
     beneficially owned, collectively, by any two or more of such persons; or
     10% or more of the voting securities of the Trustee is beneficially owned
     either by an underwriter for the Company or by any director, partner or
     executive officer thereof or is beneficially owned, collectively, by any
     two or more such persons;

          (6) the Trustee is the beneficial owner of, or holds as collateral
     security for an obligation which is in default (as hereinafter in this
     subsection defined), (i) 5% or more of the voting securities, or 10% or
     more of any other class of security, of the Company not including the Debt
     Securities issued under this Indenture and securities issued under any
     other indenture under which the Trustee is also trustee, or (ii) 10% or
     more of any class of security of an underwriter for the Company;

          (7) the Trustee is the beneficial owner of or holds as collateral
     security for an obligation which is in default, 5% or more of the voting
     securities of any person who, to the knowledge of the Trustee, owns 10% or
     more of the voting securities of, or controls directly or indirectly or is
     under direct or indirect common control with, the Company;

          (8) the Trustee is the beneficial owner of or holds as collateral
     security for an obligation which is in default, 10% or more of any class of
     security of any person who, to the knowledge of the Trustee, owns 50% or
     more of the voting securities of the Company;

                                       38
<PAGE>
 
          (9) the Trustee owns, on the date of such Event of Default or any
     anniversary of such Event of Default while such Event of Default remains
     outstanding, in the capacity of executor, administrator, testamentary or
     inter vivos trustee, guardian, committee or conservator, or in any other
     similar capacity, an aggregate of 25% or more of the voting securities, or
     of any class of security, of any person, the beneficial ownership of a
     specified percentage of which would have constituted a conflicting interest
     under paragraph (6), (7) or (8) of this subsection.  As to any such
     securities of which the Trustee acquired ownership through becoming
     executor, administrator or testamentary trustee of an estate which included
     them, the provisions of the preceding sentence shall not apply, for a
     period of not more than two years from the date of such acquisition, to the
     extent that such securities included in such estate do not exceed 25% of
     such voting securities or 25% of any such class of security.  Promptly
     after the dates of any such Event of Default and annually in each
     succeeding year that such Event of Default continues, the Trustee shall
     make a check of its holdings of such securities in any of the above-
     mentioned capacities as of such dates.  If the Company fails to make
     payment in full of the principal of (or premium, if any) or interest on any
     of the Debt Securities when and as the same becomes due and payable, and
     such failure continues for 30 days thereafter, the Trustee shall make a
     prompt check of its holdings of such securities in any of the above-
     mentioned capacities as of the date of the expiration of such 30-day
     period, and after such date, notwithstanding the foregoing provisions of
     this paragraph, all such securities so held by the Trustee, with sole or
     joint control over such securities vested in it, shall be considered as
     though beneficially owned by the Trustee for the purposes of paragraphs
     (6), (7) and (8) of this subsection; or

          (10) except under the circumstances described in paragraphs (1), (3),
     (4), (5) or (6) of Section 6.13(b) of this Indenture, the Trustee shall be
     or shall become a creditor of the Company.

          For the purposes of paragraph (1) of this subsection, the term "series
of securities" or "series" means a series, class or group of securities issuable
under an indenture pursuant to whose terms holders of one such series may vote
to direct the Trustee, or otherwise take action pursuant to a vote of such
holders, separately from holders of another series; provided, that "series of
                                                    --------                 
securities" or "series" shall not include any series of securities issuable
under an indenture if all such series rank equally and are wholly unsecured.

          The specification of percentages in paragraphs (5) to (9), inclusive,
of this subsection shall not be construed as indicating that the ownership of
such percentages of the securities of a person is or is not necessary or
sufficient to constitute direct or indirect control for the purposes of
paragraph (3) or (7) of this subsection.

          For the purposes of paragraphs (6), (7), (8) and (9) of this
subsection only, (i) the terms "security" and "securities" shall include only
such securities as are generally known as corporate securities, but shall not
include any note or other evidence of indebtedness issued to evidence an
obligation to repay moneys lent to a person by one or more banks, trust
companies or banking firms, or any certificate of interest or participation in
any such note or evidence of indebtedness; (ii) an obligation shall be deemed to
be "in default" when a default in payment of principal shall have continued for
30 days or more and shall not have been cured; and (iii) the Trustee shall not
be deemed to be the owner or holder of (A) any security which it holds as
collateral security, as trustee or otherwise, for an obligation which is not in
default as defined in clause (ii) above, or (B) any security which it holds as
collateral security under this Indenture, irrespective of any default hereunder,
or (C) any security which it holds as agent for collection, or as custodian,
escrow agent or depositary, or in any similar representative capacity.

     affairs of a person, or any security issued under or pursuant to any trust,
     agreement or arrangements whereby a trustee or trustees or agent or agents
     for the owner or holder of such security are presently entitled to vote in

     any series.

          (1) A specified percentage of the voting securities of the Trustee,
     the Company or any other person referred to in this Section (each of whom

     shares if relating to capital shares, and the number of units if relating
     to any other kind of security.

          (4) The term "outstanding" means issued and not held by or for the
     account of the issuer.  The following securities shall not be deemed
     outstanding within the meaning of this definition:

               (i) securities of an issuer held in a sinking fund relating to
          securities of the issuer of the same class;

          by such other class of securities is not in default as to principal or
          interest or otherwise;

               (iii)  securities pledged by the issuer thereof as security for
          an obligation of the issuer not in default as to principal or interest
          or otherwise; and

               (iv) securities held in escrow if placed in escrow by the issuer
          thereof;

     provided, however, that any voting securities of an issuer shall be deemed
     --------  -------                                                         
     outstanding if any person other than the issuer is entitled to exercise the
     voting rights thereof.

          (5) A security shall be deemed to be of the same class as another
     security if both securities confer upon the holder or holders thereof
     substantially the same rights and privileges; provided, however, that, in
                                                   --------  -------          
     the case of secured evidences of indebtedness, all of which are issued
     under a single indenture, differences in the interest rates or maturity
     dates of various series thereof shall not be deemed sufficient to
     constitute such series different classes; and provided, further, that, in
                                                   --------  -------          
     the case of unsecured evidences of indebtedness, differences in the
     interest rates or maturity dates thereof shall not be deemed sufficient to
     constitute them securities of different classes, whether or not they are
     issued under a single indenture.

          (f) Except in the case of a default in the payment of the principal of
or interest on any Debt Security of any series, or in the payment of any sinking
or purchase fund installment, the Trustee shall not be required to resign as
provided by this Section if the Trustee shall have sustained the burden of
proving, on application to the Commission and after opportunity for hearing
thereon, that:

          (1) the Event of Default may be cured or waived during a reasonable
     period and under the procedures described in such application; and

          (2) a stay of the Trustee's duty to resign will not be inconsistent
     with the interests of Holders of the Debt Securities.

The filing of such an application shall automatically stay the performance of
the duty to resign until the Commission orders otherwise.

of at least $75,000,000, subject to supervision or examination by Federal, State
or District of Columbia authority.  If such corporation publishes reports of
condition at least annually, pursuant to law or to the requirements of the
aforesaid supervising or examining authority, then for the purposes of this
Section, the combined capital and surplus of such corporation shall be deemed to
be its combined capital and surplus as set forth in its most recent report of
condition so published.  Neither the Company nor any person directly or
indirectly controlling, controlled by, or under common control with the Company

          Section 6.10. Resignation and Removal; Appointment of Successor.
                        ------------------------------------------------- 

          (a) No resignation or removal of the Trustee and no appointment of a
successor Trustee pursuant to this Article shall become effective until the
acceptance of appointment by the successor Trustee under Section 6.11.

          (b) The Trustee may resign at any time with respect to the Debt
Securities of one or more series by giving written notice thereof to the
Company.  If an instrument of acceptance by a successor Trustee shall not have
been delivered to the Trustee within 30 days after the giving of such notice of
resignation, the resigning Trustee may petition any court of competent
jurisdiction for the appointment of a successor Trustee with respect to the Debt
Securities of such series.

          (c) The Trustee may be removed at any time with respect to the Debt
Securities of any series and a successor Trustee appointed by Act of the Holders
of a majority in principal amount of the Outstanding Debt Securities of such
series, delivered to the Trustee and to the Company.

          (d)  If at any time:

          (1) the Trustee shall fail to comply with Section 6.08(a) with respect
     to the Debt Securities of any series after written request therefor by the
     Company or by any Holder who has been a bona fide Holder of a Debt Security
     of such series for at least six months, or

          (2) the Trustee shall cease to be eligible under Section 6.09 with
     respect to the Debt Securities of any series and shall fail to resign after
     written request therefor by the Company or by any such Holder, or

          (3) the Trustee shall become incapable of acting or shall be adjudged
     a bankrupt or insolvent or a receiver of the Trustee or of its property
     shall be appointed or any public officer shall take charge or control of
     the Trustee or of its property or affairs for the purpose of
     rehabilitation, conservation or liquidation,

then, in any such case, (i) the Company by a Board Resolution may remove the
Trustee with respect to all Debt Securities, or (ii) subject to Section 5.14,
any Holder who has been a bona fide Holder of a Debt Security of any series for
at least six months may, on behalf of himself and all others similarly situated,
petition any court of competent jurisdiction for the removal of the Trustee and
the appointment of a successor Trustee for the Debt Securities of such series.

                                       42
<PAGE>
 
          (e) If the Trustee shall resign, be removed or become incapable of
acting, or if a vacancy shall occur in the office of Trustee for any cause, with
respect to the Debt Securities of one or more series, the Company, by a Board
Resolution, shall promptly appoint a successor Trustee or Trustees with respect
to the Debt Securities of that or those series (it being understood that any
such successor Trustee may be appointed with respect to the Debt Securities of
one or more or all of such series and that at any time there shall be only one
Trustee with respect to the Debt Securities of any particular series) and shall
comply with the applicable requirements of Section 6.11.  If, within one year
after such resignation, removal or incapability, or the occurrence of such
vacancy, a successor Trustee with respect to the Debt Securities of any series
shall be appointed by Act of the Holders of a majority in principal amount of
the Outstanding Debt Securities of such series delivered to the Company and the
retiring Trustee, the successor Trustee so appointed shall, forthwith upon its
acceptance of such appointment, become the successor Trustee with respect to the
Debt Securities of such series and to that extent supersede the successor
Trustee appointed by the Company.  If no successor Trustee with respect to the
Debt Securities of any series shall have been so appointed by the Company or the
Holders of such series and accepted appointment in the manner hereinafter
provided, any Holder who has been a bona fide Holder of a Debt Security of such
series for at least six months may, subject to Section 5.14, on behalf of
himself and all others similarly situated, petition any court of competent
jurisdiction for the appointment of a successor Trustee with respect to the Debt
Securities of such series.

          (f) The Company shall give notice of each resignation and each removal
of the Trustee with respect to the Debt Securities of any series and each
appointment of a successor Trustee with respect to the Debt Securities of any
series in the manner and to the extent provided in Section 1.05 to the Holders
of Debt Securities of such series.  Each notice shall include the name of the
successor Trustee with respect to the Debt Securities of such series and the
address of its Corporate Trust Office.

          Section 6.11. Acceptance of Appointment by Successor.
                        -------------------------------------- 

          (a) In the case of an appointment hereunder of a successor Trustee
with respect to all Debt Securities, each such successor Trustee so appointed
shall execute, acknowledge and deliver to the Company and to the retiring
Trustee an instrument accepting such appointment, and thereupon the resignation
or removal of the retiring Trustee shall become effective and such successor
Trustee, without any further act, deed or conveyance, shall become vested with
all the rights, powers, trusts and duties of the retiring Trustee, but, on
request of the Company or the successor Trustee, such retiring Trustee shall,
upon payment of its charges, execute and deliver an instrument transferring to
such successor Trustee all the rights, powers and trusts of the retiring
Trustee, and shall duly assign, transfer and deliver to such successor Trustee
all property and money held by such retiring Trustee hereunder, subject
nevertheless to its claim, if any, provided for in Section 6.07.

          (b) In case of the appointment hereunder of a successor Trustee with
respect to the Debt Securities of one or more (but not all) series, the Company,
the retiring Trustee and each successor Trustee with respect to the Debt
Securities of one or more series shall execute and deliver an indenture
supplemental hereto wherein each successor Trustee shall accept such appointment
and which (1) shall contain such provisions as shall be necessary or desirable
to transfer and confirm to, and to vest in, each successor Trustee all the
rights, powers, trusts and duties of the retiring Trustee with respect to the
Debt Securities of that or those series to which the appointment of such
successor Trustee relates, (2) if the retiring Trustee is not retiring with
respect to all Debt Securities, shall contain such provisions as shall be deemed
necessary or desirable to confirm that all the rights, powers, trusts and duties
of the retiring Trustee with respect to the Debt Securities of that or those
series as to which the retiring Trustee is not retiring shall continue to be
vested in the retiring Trustee, and (3) shall add to or change any of the
provisions of this Indenture as shall be necessary to provide for or facilitate
the administration of the

                                       43

trusts hereunder by more than one Trustee, it being understood that nothing
herein or in any such supplemental indenture shall constitute such Trustees co-
trustees of the same trust and that each such Trustee shall be trustee of a
trust or trusts hereunder separate and apart from any other trust or trusts
hereunder administered by any other such Trustee; and upon the execution and
delivery of any such supplemental indenture the resignation or removal of the
retiring Trustee shall become effective to the extent provided therein and each
such successor Trustee, without any further act, deed or conveyance, shall
become vested with all the rights, powers, trusts and duties of the retiring
Trustee with respect to the Debt Securities of that or those series to which the
appointment of such successor Trustee relates, but, on request of the Company or
any successor Trustee, such retiring Trustee shall duly assign, transfer and
deliver to such successor Trustee all property and money held by such retiring
Trustee hereunder with respect to the Debt Securities of that or those series to
which the appointment of such successor Trustee relates.

          (c) Upon request of any such successor Trustee, the Company shall
execute any and all instruments for more fully and certainly vesting in and
confirming to such successor Trustee all such rights, powers and trusts referred
to in paragraph (a) or (b) of this Section, as the case may be.

          (d) No successor Trustee shall accept its appointment unless at the
time of such acceptance such successor Trustee shall be qualified and eligible
under this Article.

          Section 6.12. Merger, Conversion, Consolidation or Succession to
                        --------------------------------------------------
Business.
- -------- 

          Any corporation into which the Trustee may be merged or converted or
with which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to all or substantially all of the corporate trust
business of the Trustee, shall be the successor of the Trustee hereunder,
provided that such corporation shall be otherwise qualified and eligible under
this Article, without the execution or filing of any paper or any further act on
the part of any of the parties hereto.  In case any Debt Securities shall have
been authenticated, but not delivered, by the Trustee then in office, any
successor by merger, conversion or consolidation to such authenticating Trustee
may adopt such authentication and deliver the Debt Securities so authenticated
with the same effect as if such successor Trustee had itself authenticated such
Debt Securities.  In case any Debt Securities shall not have been authenticated
by such predecessor Trustee, any such successor Trustee may authenticate and
deliver such Debt Securities, in either its own name or that of its predecessor
Trustee, with the full force and effect which this Indenture provides for the
certificate of authentication of the Trustee.

          Section 6.13. Preferential Collection of Claims Against Company.
                        ------------------------------------------------- 

          (a)  Subject to subsection (b) of this Section, if the Trustee shall
be or shall become a creditor, directly or indirectly, secured or unsecured, of
the Company within three months prior to a default, as defined in subsection (c)
of this Section, or subsequent to such default, then, unless and until such
default shall be cured, the Trustee shall set apart and hold in a special
account for the benefit of the Trustee individually, the Holders of the Debt
Securities and the holders of other indenture securities (as defined in
subsection (c) of this Section):

          (1)  an amount equal to any and all reductions in the amount due and
     owing upon any claim as such creditor in respect of principal or interest,
     effected after the beginning of such three-month period and valid as
     against the Company and its other creditors, except any such reduction
     resulting from the receipt or disposition of any property described in
     paragraph (2) of this subsection, or from the exercise of any right of set-
     off which the Trustee could have

                                       44
<PAGE>
 
     exercised if a voluntary or involuntary case had been commenced in respect
     of the Company under the Federal bankruptcy laws, as now or hereafter
     constituted, or any other applicable Federal or State bankruptcy,
     insolvency or other similar law upon the date of such default; and

          (2)  all property received by the Trustee in respect of any claim as
     such creditor, either as security therefor, or in satisfaction or
     composition thereof, or otherwise, after the beginning of such three-month
     period, or an amount equal to the proceeds of any such property, if
     disposed of, subject, however, to the rights, if any, of the Company and
                  -------  -------                                           
     its other creditors in such property or such proceeds.

Nothing herein contained, however, shall affect the right of the Trustee:

          (A)  to retain for its own account (i) payments made on account of any
     such claim by any Person (other than the Company) who is liable thereon,
     and (ii) the proceeds of the bona fide sale of any such claim by the
     Trustee to a third Person, and (iii) distributions made in cash, securities
     or other property in respect of claims filed against the Company in
     bankruptcy or receivership or in proceedings or reorganization pursuant to
     the Federal bankruptcy laws, as now or hereafter constituted, or any other
     applicable Federal or State bankruptcy, insolvency or other similar law;

          (B)  to realize, for its own account, upon any property held by it as
     security for any such claim, if such property was so held prior to the
     beginning of such three-month period;

          (C)  to realize, for its own account, but only to the extent of the
     claim hereinafter mentioned, upon any property held by it as security for
     any such claim, if such claim was created after the beginning of such
     three-month period and such property was received as security therefor
     simultaneously with the creation thereof, and if the Trustee shall sustain
     the burden of proving that at the time such property was so received the
     Trustee had no reasonable cause to believe that a default, as defined in
     subsection (c) of this Section, would occur within three months, or

          (D)  to receive payment on any claim referred to in paragraph (B) or
     (C) against the release of any property held as security for such claim as
     provided in paragraph (B) or (C), as the case may be, to the extent of the
     fair value of such property.

          For the purposes of paragraphs (B), (C) and (D), property substituted
after the beginning of such three-month period for property held as security at
the time of such substitution shall, to the extent of the fair value of the
property released, have the same status as the property released, and, to the
extent that any claim referred to in any of such paragraphs is created in
renewal of or in substitution for or for the purpose of repaying or refunding
any pre-existing claim of the Trustee as such creditor, such claim shall have
the same status as such pre-existing claim.

          If the Trustee shall be required to account, the funds and property
held in such special account and the proceeds thereof shall be apportioned among
the Trustee, the Holders and the holders of other indenture securities in such
manner that the Trustee, the Holders and the holders of other indenture
securities realize, as a result of payments from such special account and
payments of dividends on claims filed against the Company in bankruptcy or
receivership or in proceedings for reorganization pursuant to the Federal
bankruptcy laws, as now or hereafter constituted or any other applicable Federal
or State bankruptcy, insolvency or other similar law, the same percentage of
their respective claims, figured before crediting to the claim of the Trustee
anything on account of the receipt by it from the Company of the funds and
property in such special account and before crediting to the respective claims

                                       45
<PAGE>
 
of the Trustee and the Holders and the holders of other indenture securities
dividends on claims filed against the Company in bankruptcy or receivership or
in proceedings for reorganization pursuant to the Federal bankruptcy laws, as
now or hereafter constituted, or any other applicable Federal or State
bankruptcy, insolvency or other similar law, but after crediting thereon
receipts on account of the indebtedness represented by their respective claims
from all sources other than from such dividends and from the funds and property
so held in such special account.  As used in this paragraph, with respect to any
claim, the term "dividends" shall include any distribution with respect to such
claim, in bankruptcy or receivership or proceedings for reorganization pursuant
to the Federal bankruptcy laws, as now or hereafter constituted, or any other
applicable Federal or State bankruptcy, insolvency or other similar law, whether
such distribution is made in cash, securities, or other property, but shall not
include any such distribution with respect to the secured portion, if any, of
such claim.  The court in which such bankruptcy, receivership or proceedings for
reorganization is pending shall have jurisdiction (i) to apportion among the
Trustee and the Holders and the holders of other indenture securities, in
accordance with the provisions of this paragraph, the funds and property held in
such special account and proceeds thereof, or (ii) in lieu of such
apportionment, in whole or in part, to give to the provisions of this paragraph
due consideration in determining the fairness of the distributions to be made to
the Trustee and the Holders and the holders of other indenture securities with
respect to their respective claims, in which event it shall not be necessary to
liquidate or to appraise the value of any securities or other property held in
such special account or as security for any such claim, or to make a specific
allocation of such distributions as between the secured and unsecured portions
of such claim, or otherwise to apply the provisions of this paragraph as a
mathematical formula.

          Any Trustee which has resigned or been removed after the beginning of
such three-month period shall be subject to the provisions of this subsection as
though such resignation or removal had not occurred.  If any Trustee has
resigned or been removed prior to the beginning of such three-month period, it
shall be subject to the provisions of this subsection if and only if the
following conditions exist:

          (i)  the receipt of property or reduction of claim, which would have
     given rise to the obligation to account, if such Trustee had continued as
     Trustee, occurred after the beginning of such three-month period; and

          (ii)  such receipt of property or reduction of claim occurred within
     three months after such resignation or removal.

          (b) There shall be excluded from the operation of subsection (a) of
this Section a creditor relationship arising from:

          (1)  the ownership or acquisition of securities issued under any
     indenture, or any security or securities having a maturity of one year or
     more at the time of acquisition by the Trustee;

          (2)  advances authorized by a receivership or bankruptcy court of
     competent jurisdiction or by this Indenture, for the purpose of preserving
     any property which shall at any time be subject to the Lien of this
     Indenture or of discharging tax liens or other prior liens or encumbrances
     thereon, if notice of such advances and of the circumstances surrounding
     the making thereof is given to the Holders at the time and in the manner
     provided in this Indenture;

          (3)  disbursements made in the ordinary course of business in the
     capacity of trustee under an indenture, transfer agent, registrar,
     custodian, paying agent, fiscal agent or depositary, or other similar
     capacity;

                                       46
<PAGE>
 
          (4)  an indebtedness created as a result of services rendered or
     premises rented, or an indebtedness created as a result of goods or
     securities sold in a cash transaction as defined in subsection (c) of this
     Section;

          (5)  the ownership of stock or of other securities of a corporation
     organized under the provisions of Section 25(a) of the Federal Reserve Act,
     as amended, which is directly or indirectly a creditor of the Company; and

          (6)  The acquisition, ownership, acceptance or negotiation of any
     drafts, bills of exchange, acceptances or obligations which fall within the
     classification of self-liquidating paper as defined in subsection (c) of
     this Section.

          (c)  for the purposes of this Section only:

          (1)  The term "default" means any failure to make payment in full of
     the principal of or interest on any of the Debt Securities or upon the
     other indenture securities when and as such principal or interest becomes
     due and payable.

          (2)  The term "other indenture securities" means securities upon which
     the Company is an obligor outstanding under any other indenture (i) under
     which the Trustee is also trustee, (ii) which contains provisions
     substantially similar to the provisions of this Section, and (iii) under
     which a default exists at the time of the apportionment of the funds and
     property held in such special account.

          (3)  The term "cash transaction" means any transaction in which full
     payment for goods or securities sold is made within seven days after
     delivery of the goods or securities in currency or in checks or other
     orders drawn upon banks and payable upon demand.

          (4)  The term "self-liquidating paper" means any draft, bill of
     exchange, acceptance or obligation which is made, drawn, negotiated or
     incurred by the Company for the purpose of financing the purchase,
     processing, manufacturing, shipment, storage or sale of goods, wares or
     merchandise and which is secured by documents evidencing title to,
     possession of, or a lien upon, the goods, wares or merchandise or the
     receivables or proceeds arising from the sale of the goods, wares or
     merchandise previously constituting the security, provided the security is
     received by the Trustee simultaneously with the creation of the creditor
     relationship with the Company arising from the making, drawing, negotiating
     or incurring of the draft, bill of exchange, acceptance or obligation.

          (5)  The term "Company" means any obligor upon the Debt Securities.

          Section 6.14. Appointment of Authenticating Agent.
                        ----------------------------------- 

          As long as any Debt Securities of a series remain Outstanding, upon a
Company Request, there shall be an authenticating agent (the "Authenticating
Agent") appointed, for such period as the Company shall elect, by the Trustee
for such series of Debt Securities to act as its agent on its behalf and subject
to its direction in connection with the authentication and delivery of each
series of Debt Securities for which it is serving as Trustee.  Debt Securities
of each such series authenticated by such Authenticating Agent shall be entitled
to the benefits of this Indenture and shall be valid and obligatory for all
purposes as if authenticated by such Trustee.  Wherever reference is made in
this Indenture to the authentication and delivery of Debt Securities of any
series by the Trustee for such series or to the

                                       47
<PAGE>
 
Trustee's Certificate of Authentication, such reference shall be deemed to
include authentication and delivery on behalf of the Trustee for such series by
an Authenticating Agent for such series and a Certificate of Authentication
executed on behalf of such Trustee by such Authenticating Agent.  Such
Authenticating Agent shall at all times be a corporation organized and doing
business under the laws of the United States of America or of any State,
authorized under such laws to exercise corporate trust powers, having a combined
capital and surplus of at least $10,000,000 and subject to supervision or
examination by Federal or State authority.  If such Authenticating Agent
publishes reports of condition at least annually, pursuant to law or to the
requirements of said supervising or examining authority, then for purposes of
this Section, the combined capital and surplus of such Authenticating Agent
shall be deemed to be its combined capital and surplus as set forth in its most
recent report of condition so published.  If at any time an Authenticating Agent
shall cease to be eligible in accordance with the provisions of this Section,
such Authenticating Agent shall resign immediately in the manner and with the
effect specified in this Section.

          Any corporation into which any Authenticating Agent may be merged or
converted, or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which any Authenticating Agent
shall be a party, or any corporation succeeding to the corporate agency business
of any Authenticating Agent, shall continue to be the Authenticating Agent with
respect to all series of Debt Securities for which it served as Authenticating
Agent without the execution or filing of any paper or any further act on the
part of the Trustee for such series or such Authenticating Agent.  Any
Authenticating Agent may at any time, and if it shall cease to be eligible
shall, resign by giving written notice of resignation to the applicable Trustee
and to the Company.

          Upon receiving such a notice of resignation or upon such a
termination, or in case at any time any Authenticating Agent shall cease to be
eligible in accordance with the provisions of this Section 6.14 with respect to
one or more or all series of Debt Securities, the Trustee for such series shall
upon Company Request appoint a successor Authenticating Agent, and the Company
shall provide notice of such appointment to all Holders of Debt Securities of
such series in the manner and to the extent provided in Section 1.05.  Any
successor Authenticating Agent upon acceptance of its appointment hereunder
shall become vested with all rights, powers, duties and responsibilities of its
predecessor hereunder, with like effect as if originally named as Authenticating
Agent herein.  The Company agrees to pay to the Authenticating Agent for such
series from time to time reasonable compensation for its services.  The
Authenticating Agent for the Debt Securities of any series shall have no
responsibility or liability for any action taken by it as such at the direction
of the Trustee for such series.

                                       48
<PAGE>
 
          If an appointment with respect to one or more series is made pursuant
to this Section, the Debt Securities of such series may have endorsed thereon,
in addition to the Trustee's certificate of authentication, an alternative
certificate of authentication in the following form:

          This is one of the series of Debt Securities issued under the within
mentioned Indenture.

          Section 7.01. Company to Furnish Trustee Names and Addresses of
                        -------------------------------------------------
Holders.
- ------- 

          The Company will furnish or cause to be furnished to the Trustee with
respect to Registered Securities of each series for which it acts as Trustee:

          (a) semi-annually on a date not more than 15 days after each Regular
Record Date with respect to an Interest Payment Date, if any, for the Registered
Securities of such series (or on semi-annual dates in each year to be determined
pursuant to Section 3.01 if the Registered Securities of such series do not bear
interest), a list, in such form as the Trustee may reasonably require, of the
names and addresses of the Registered Holders as of the date 15 days next
preceding each such Regular Record Date (or such semi-annual dates, as the case
may be); and

          (b) at such other times as the Trustee may request in writing, within
30 days after the receipt by the Company of any such request, a list of similar
form and content as of a date not more than 15 days prior to the time such list
is furnished;

provided, however, that if and so long as the Trustee shall be the Security
- --------  -------                                                          
Registrar for such series, no such list need be furnished.

          Section 7.02. Preservation of Information; Communication to Holders.
                        ----------------------------------------------------- 

          (a) The Trustee shall preserve, in as current a form as is reasonably
practicable, all information as to the names and addresses of Holders contained
in the most recent list furnished to the Trustee as provided in Section 7.01
received by it in the capacity of Paying Agent (if so acting) hereunder, and
filed with it within the two preceding years pursuant to Section 7.03(c)(2).

          The Trustee may destroy any list furnished to it as provided in
Section 7.01 upon receipt of a new list so furnished, destroy any information
received by it as Paying Agent (if so acting) hereunder

                                       49
<PAGE>
 
upon delivering to itself as Trustee, not earlier than 45 days after an Interest
Payment Date, a list containing the names and addresses of the Holders obtained
from such information since the delivery of the next previous list, if any,
destroy any list delivered to itself as Trustee which was compiled from
information received by it as Paying Agent (if so acting) hereunder upon the
receipt of a new list so delivered, and destroy not earlier than two years after
filing, any information filed with it pursuant to Section 7.03(c)(2).

          (b)If three or more Holders (hereinafter referred to as "applicants")
apply in writing to the Trustee, and furnish to the Trustee proof reasonably
satisfactory to the Trustee that each such applicant has owned a Debt Security
for a period of at least six months preceding the date of such application, and
such application states that the applicants desire to communicate with other
Holders of Debt Securities of a particular series (in which case the applicants
must hold Debt Securities of such series) or with all Holders of Debt Securities
with respect to their rights under this Indenture or under the Debt Securities
and is accompanied by a copy of the form of proxy or other communication which
such applicants propose to transmit, then the Trustee shall, within five
Business Days after the receipt of such application, at its election, either

          (i) afford such applicants access to the information preserved at the
     time by the Trustee in accordance with Section 7.02(a), or

          (ii) inform such applicants as to the approximate number of Holders of
     Debt Securities of such series or of all Debt Securities, as the case may
     be, whose names and addresses appear in the information preserved at the
     time by the Trustee in accordance with Section 7.02(a), and as to the
     approximate cost of mailing to such Holders the form of proxy or other
     communication, specified in such application.

          If the Trustee shall elect not to afford such applicants access to
such information, the Trustee shall, upon written request of such applicants,
mail to the Holders of Debt Securities of such series or all Holders, as the
case may be, whose names and addresses appear in the information preserved at
the time by the Trustee in accordance with Section 7.02(a), a copy of the form
of proxy or other communication which is specified in such request, with
reasonable promptness after a tender to the Trustee of the material to be mailed
and of payment, or provision for the payment, of the reasonable expenses of
mailing, unless within five days after such tender, the Trustee shall mail to
such applicants and file with the Commission, together with a copy of the
material to be mailed, a written statement to the effect that, in the opinion of
the Trustee, such mailing would be contrary to the best interests of the Holders
of Debt Securities of such series or all Holders, as the case may be, or would
be in violation of applicable law.  Such written statement shall specify the
basis of such opinion.  If the Commission, after opportunity for a hearing upon
the objections specified in the written statement so filed, shall enter an order
refusing to sustain any of such objections or if after the entry of an order
sustaining one or more of such objections, the Commission shall find, after
notice and opportunity for hearing, that all the objections so sustained have
been met and shall enter an order so declaring, the Trustee shall mail copies of
such material to all such Holders with reasonable promptness after the entry of
such order and the renewal of such tender; otherwise the Trustee shall be
relieved of any obligation or duty to such applicants respecting their
application.

          (c) Every Holder of Debt Securities, by receiving and holding the
same, agrees with the Company and the Trustee that neither the Company nor the
Trustee shall be held accountable by reason of the disclosure of any such
information as to the names and addresses of the Holders in accordance with
Section 7.02(b), regardless of the source from which such information was
derived, and

                                       50

that the Trustee shall not be held accountable by reason of mailing of any
material pursuant to a request made under Section 7.02(b).

                        ------------------ 

          (a)  Within 60 days after January 15 of each year, commencing January
15, 1998, the Trustee shall, to the extent required by the Trust Indenture Act,
transmit to all Holders of Debt Securities of any series with respect to which
it acts as Trustee, in the manner hereinafter provided in this Section 7.03, a
brief report dated such date with respect to any of the following events which
may have occurred within the previous 12 months (but if no such event has
occurred within such period no report need be transmitted):

          (1) any change to its eligibility under Section 6.09 and its
     qualifications under Section 6.08;

     elects so to state, the circumstances surrounding the making thereof) made
     by the Trustee (as such) which remain unpaid on the date of such report,
     and for the reimbursement of which it claims or may claim a lien or charge,
     prior to that of the Debt Securities of such series, on any property or
     funds held or collected by it as Trustee, except that the Trustee shall not
     be required (but may elect) to report such advances if such advances so
     remaining unpaid aggregate not more than 1/2 of 1% of the principal amount
     of the Outstanding Debt Securities of such series on the date of such
     report;

          (4) any change to the amount, interest rate and maturity date of all
     other indebtedness owing by the Company (or any other obligor on the Debt
     Securities of such series) to the Trustee in its individual capacity, on
     the date of such report, with a brief description of any property held as
     collateral security therefor, except an indebtedness based upon a creditor
     relationship arising in any manner described in Section 6.13(b)(2), (3),
     (4) or (6);

          (5) any change to the property and funds, if any, physically in the
     possession of the Trustee as such on the date of such report;

          (6) any additional issue of Debt Securities which the Trustee has not
     previously reported; and

          (7) any action taken by the Trustee in the performance of its duties
     hereunder which it has not previously reported and which in its opinion

Securities of any series (whose names and addresses appear in the information

which it acts as the Trustee, as hereinafter provided, a brief report with
respect to the character and amount of any advances (and if the Trustee elects
so to state, the circumstances surrounding the making thereof) made by the
Trustee (as such) since the date of the last report transmitted pursuant to
subsection (a) of this Section (or if no such report has yet been so
transmitted, since the date

such advances remaining unpaid at any time aggregate 10% or less of the
principal amount of the Debt Securities of such series Outstanding at such time,
such report to be transmitted within 90 days after such time.

     Section 7.03, to each Holder of a Debt Security of any series whose name
     and address appear in the information preserved at the time by the Trustee
     in accordance with Section 7.02(a).

          (d)  A copy of each such report shall, at the time of such
transmission to Holders, be filed by the Trustee with each stock exchange upon
which any Debt Securities of such series are listed, with the Commission and

     rules and regulations prescribe) which the Company may be required to file
     with the Commission pursuant to Section 13 or Section 15(d) of the

                            CONCERNING THE HOLDERS

          Section 8.01. Acts of Holders.
                        --------------- 

          Any request, demand, authorization, direction, notice, consent, waiver
or other action provided by this Indenture to be given or taken by Holders may
be embodied in and evidenced by one or more instruments of substantially similar
tenor signed by such Holders in person or by an agent or proxy duly appointed in
writing; and, except as herein otherwise expressly provided, such action shall
become effective when such instrument or instruments are delivered to the
Trustee, and, where it is hereby expressly required, to the Company.  Such
instrument or instruments (and the action embodied therein and evidenced
thereby) are herein sometimes referred to as the "Act" of the Holders signing
such instrument or instruments.  Whenever in this Indenture it is provided that
the Holders of a specified percentage in aggregate principal amount of the
Outstanding Debt Securities of any series may take any Act, the fact that the
Holders of such specified percentage have joined therein may be evidenced (a) by
the instrument or instruments executed by Holders in person or by agent or proxy
appointed in writing, or (b) by the record of Holders voting in favor thereof at
any meeting of such Holders duly called and held in accordance with the
provisions of Article Nine, or (c) by a combination of such instrument or
instruments and any such record of such a meeting of Holders.

          Section 8.02. Proof of Ownership; Proof of Execution of Instruments
                        -----------------------------------------------------
by Holder.
- --------- 

          The ownership of Registered Securities of any series shall be proved
by the Security Register for such series or by a certificate of the Security
Registrar for such series.

          Subject to the provisions of Sections 6.01, 6.03 and 9.05, proof of
the execution of a writing appointing an agent or proxy and of the execution of
any instrument by a Holder or his agent or proxy shall be sufficient and
conclusive in favor of the Trustee and the Company if made in the following
manner:

          The fact and date of the execution by any such person of any
instrument may be proved by the certificate of any notary public or other
officer authorized to take acknowledgements of deeds, that the person executing
such instrument acknowledged to him the execution thereof, or by an affidavit of
a witness to such execution sworn to before any such notary or other such
officer.  Where such execution is by an officer of a corporation or association
or a member of a partnership on behalf of such

                                       53
<PAGE>
 
corporation, association or partnership, as the case may be, or by any other
person acting in a representative capacity, such certificate or affidavit shall
also constitute sufficient proof of his authority.

          The record of any Holders' meeting shall be proved in the manner
provided in Section 9.06.

          The Trustee may in any instance require further proof with respect to
any of the matters referred to in this Section so long as the request is a
reasonable one.

          Section 8.03. Persons Deemed Owners.
                        --------------------- 

          The Company, the Trustee and any agent of the Company or the Trustee
may treat the Person in whose name any Registered Security is registered as the
owner of such Registered Security for the purpose of receiving payment of the
principal of (and premium, if any) and (subject to Section 3.07) interest, if
any, on such Registered Security and for all other purposes whatsoever, whether
or not such Registered Security be overdue, and neither the Company, the Trustee
nor any agent of the Company or the Trustee shall be affected by notice to the
contrary.  All payments made to any Holder, or upon his order, shall be valid,
and, to the extent of the sum or sums paid, effectual to satisfy and discharge
the liability for moneys payable upon such Debt Security.

          Section 8.04. Revocation of Consents; Future Holders Bound.
                        -------------------------------------------- 

          At any time prior to (but not after) the evidencing to the Trustee, as
provided in Section 8.01, of the taking of any Act by the Holders of the
percentage in aggregate principal amount of the Outstanding Debt Securities
specified in this Indenture in connection with such Act, any Holder of a Debt
Security the number, letter or other distinguishing symbol of which is shown by
the evidence to be included in the Debt Securities the Holders of which have
consented to such Act may, by filing written notice with the Trustee at the
Corporate Trust Office and upon proof of ownership as provided in Section 8.02,
revoke such Act so far as it concerns such Debt Security.  Except as aforesaid,
any such Act taken by the Holder of any Debt Security shall be conclusive and
binding upon such Holder and, subject to the provisions of Section 5.08, upon
all future Holders of such Debt Security and of any Debt Securities issued on
transfer or in lieu thereof or in exchange or substitution therefor,
irrespective of whether or not any notation in regard thereto is made upon such
Debt Security or such other Debt Securities.

the Holders of at least 10% in aggregate principal amount of the Outstanding

Resolution, and the Trustee may enter into an indenture or indentures
supplemental hereto for the purpose of adding any provisions to or changing in
any manner or eliminating any of the provisions of this Indenture or of
modifying in any manner the rights of the Holders under this Indenture of such
Debt Securities provided, however, that no such supplemental indenture shall,
                --------  -------

     principal of, or installment of interest, if any, on, any Debt Security, or
     reduce the principal amount thereof or the interest thereon or any premium
     payable upon redemption thereof (provided that a requirement to offer to
     repurchase Debt Securities shall not be deemed a redemption for this
     purpose), or change the Stated Maturity of, or reduce the amount of the
     principal of a Discount Security that would be due and payable upon a
     declaration of acceleration of the Maturity thereof pursuant to Section

     defaults hereunder and their consequences provided for in this Indenture;

          (4) modify any of the provisions of this Section, Section 5.13 or
     Section 12.07, except to increase any such percentage or to provide that
     certain other provisions of this Indenture cannot be modified or waived
     without the consent of the Holder of each Outstanding Debt Security of each

     subordination of the Debt Securities in a manner adverse to the Holders.

          It shall not be necessary for any Act of Holders under this Section to
approve the particular form of any proposed supplemental indenture, but it shall
be sufficient if such Act shall approve the substance thereof.

other provision of this Indenture with respect to one or more particular series

                             ------------------------------------------ 

          The Company covenants and agrees for the benefit of each series of
Debt Securities that it will duly and punctually pay the principal of (and
premium, if any) and interest on the Debt Securities in accordance with the
terms of the Debt Securities and this Indenture.  If so provided in the terms of
any series of Debt Securities established as provided in Section 3.01, the
interest, if any, due in respect of any temporary Global Note or permanent
Global Note, together with any additional amounts payable in respect thereof, as
provided in the terms and conditions of such Debt Security, shall be payable
only upon presentation of such Debt Security to the Trustee for notation thereon
of the payment of such interest.

                             ----------------------------------- 

          Unless otherwise specifically provided for with respect to any series
of Debt Securities under Section 3.01, the Company will deliver to the Trustee,
on or before a date not more than four months after the end of each fiscal year
of the Company (which on the date hereof is the calendar year) ending after the
date hereof, a certificate of the principal executive officer, principal
financial officer or principal accounting officer of the Company stating whether
or not to the best knowledge of the signer thereof the Company is in compliance
with all covenants and conditions under this Indenture, and, if the Company
shall be in default, specifying all such defaults and the nature thereof of
which such signer may have knowledge.  For purposes of this Section, such
compliance shall be determined without regard to any period of grace or
requirement of notice provided under this Indenture.

          Section 12.03.     Maintenance of Office or Agency.
                             -------------------------------

an office or agency where Debt Securities of that series may be presented or
surrendered for payment, where Debt Securities of that series may be surrendered
for registration of transfer or exchange, where Debt Securities of that series
that are convertible may be surrendered for conversion, if applicable, and where
notices and demands to or upon the Company in respect of the Debt Securities of
that series and this Indenture may be served.  The Company will 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 and the Company hereby
appoints the Trustee as its agent to receive all presentations, surrenders,
notices and demands.

                                       61

          The Company may also from time to time designate different or
additional offices or agencies to be maintained for such purposes (in or outside
of such Place of Payment), and may from time to time rescind any such
designations.  The Company will give prompt written notice to the Trustee of any
such additional designation or rescission of designation and any change in the
location of any such different or additional office or agency.

Trust.
- ----- 

          If the Company shall at any time act as its own Paying Agent with
respect to any series of Debt Securities it will, on or before each due date of
the principal of (and premium, if any) or interest on any of the Debt Securities
of such series, segregate and hold in trust for the benefit of the Persons
entitled thereto a sum sufficient to pay the principal (and premium, if any) or
interest so becoming due until such sums shall be paid to such Persons or
otherwise disposed of as herein provided, and will promptly notify the Trustee
of its action or failure so to act.

          Whenever the Company shall have one or more Paying Agents with respect
to any series of Debt Securities, it will, by or on each due date of the
principal (and premium, if any) or interest on any Debt Securities of such
series, deposit with any such Paying Agent a sum sufficient to pay the principal
(and premium, if any) or interest so becoming due, such sum to be held in trust
for the benefit of the Persons entitled thereto, and (unless any such Paying
Agent is the Trustee) the Company will promptly notify the Trustee of its action
or failure so to act.

          The Company will cause each Paying Agent with respect to any series of
Debt Securities other than the Trustee to execute and deliver to the Trustee an
instrument in which such Paying Agent shall agree with the Trustee, subject to
the provisions of this Section, that such Paying Agent will:

          (1) hold all sums held by it for the payment of the principal of (and
     premium, if any) or interest on Debt Securities of such series in trust for
     the benefit of the Persons entitled thereto until such sums shall be paid
     to such Persons or otherwise disposed of as herein provided;

          (2) give the Trustee notice of any default by the Company (or any
     other obligor upon the Debt Securities of such series) in the making of any
     payment of principal (and premium, if any) or interest on the Debt
     Securities of such series; and

          (3) at any time during the continuance of any such default, upon the
     written request of the Trustee, forthwith pay to the Trustee all sums so
     held in trust by such Paying Agent.

          The Company may at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture or for any other purpose, pay, or
by Company Order direct any Paying Agent to pay, to the Trustee all sums held in
trust by the Company or such Paying Agent, such sums to be held by the Trustee
upon the same trusts as those upon which such sums were held by the Company or
such Paying Agent; and, upon such payment by any Paying Agent to the Trustee,
such Paying Agent shall be released from all further liability with respect to
such money.

          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 (and premium, if
any) or interest on any Debt Security of any series 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 upon Company Request, or (if then held
by the Company) shall be discharged from such trust; and the Holder of such Debt
Security shall thereafter, as an unsecured general creditor, look only to the
Company for payment thereof, and all

                                       62

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
transmitted in the manner and to the extent provided by Section 1.05, 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, any
unclaimed balance of such money then remaining will be repaid to the Company.

          Section 12.05.     Corporate Existence.

          Subject to Article Ten, the Company will do or cause to be done all
things necessary to preserve and keep in full force and effect its corporate
existence, rights (charter and statutory) and franchises; provided, however,
                                                          --------  -------

if the Company shall determine that the preservation thereof is no longer
desirable in the conduct of the business of the Company.

                               --------------------------- 

          The Company may omit in any particular instance to comply with any
term, provision or condition set forth in Section 12.05 (and, if so specified
pursuant to Section 3.01, any other covenant not set forth herein and specified
pursuant to Section 3.01 to be applicable to the Securities of any series,
except as otherwise provided pursuant to Section 3.01) with respect to the Debt
Securities of any series if before the time for such compliance the Holders of
at least a majority in principal amount of the Outstanding Debt Securities of
such series shall, by Act of such Holders, either waive such compliance in such
instance or generally waive compliance with such term, provision or condition,
but no such waiver shall extend to or affect such term, provision or condition
except to the extent expressly so waived, and, until such waiver shall become
effective, the obligations of the Company and the duties of the Trustee in
respect of any such term, provision or condition shall remain in full force and
effect.

                         REDEMPTION OF DEBT SECURITIES

          Section 13.01.     Applicability of Article.
                             ------------------------ 

     Debt Securities of any series which are redeemable before their Maturity
shall be redeemable in accordance with their terms and (except as otherwise
specified pursuant to Section 3.01 for Debt Securities of any series) in
accordance with this Article.

          Section 13.02.     Election to Redeem; Notice to Trustee.
                             ------------------------------------- 

          The election of the Company to redeem (or, in the case of Discount
Securities, to permit the Holders to elect to surrender for redemption) any Debt
Securities shall be evidenced by a Board Resolution.  In case of any redemption
at the election of the Company of less than all of the Debt Securities of any
series pursuant to Section 13.03, the Company shall, at least 60 days before the
Redemption Date fixed by the Company (unless a shorter notice shall be
satisfactory to the Trustee), notify the Trustee of such Redemption Date and of
the principal amount of Debt Securities of such series to be redeemed.  In the
case of any redemption of Debt Securities prior to the expiration of any
restriction on such redemption provided in the terms of such Debt Securities or
elsewhere in this

                                       63

Indenture, the Company shall furnish the Trustee with an Officers' Certificate
evidencing compliance with such restrictions.

                             ---------------------------------------------
Redeemed.
- -------- 

          Except in the case of a redemption in whole of the Registered
Securities of such series, if less than all the Debt Securities of any series
are to be redeemed at the election of the Company, the particular Debt
Securities to be redeemed shall be selected not more than 60 days prior to the
Redemption Date by the Trustee, from the Outstanding Debt Securities of such
series not previously called for redemption, by such method as the Trustee shall
deem fair and appropriate and which may provide for the selection for redemption
of portions (equal to the minimum authorized denomination for Debt Securities of
such series or any integral multiple thereof) of the principal amount of Debt
Securities of such series in a denomination larger than the minimum authorized
denomination for Debt Securities of such series pursuant to Section 3.02.  The
portions of the principal amount of Debt Securities so selected for partial
redemption shall be equal to the minimum authorized denominations for Debt
Securities of such series pursuant to Section 3.02 or any integral multiple
thereof, except as otherwise set forth in the applicable form of Debt
Securities.  In any case when more than one Registered Security of such series
is registered in the same name, the Trustee in its discretion may treat the
aggregate principal amount so registered as if it were represented by one
Registered Security of such series.

          The Trustee shall promptly notify the Company in writing of the Debt
Securities selected for redemption and, in the case of any Debt Securities
selected for partial redemption, the principal amount thereof to be redeemed.

          For all purposes of this Indenture, unless the context otherwise
requires, all provisions relating to the redemption of Debt Securities shall
relate, in the case of any Debt Security redeemed or to be redeemed only in
part, to the portion of the principal amount of such Debt security which has
been or is to be redeemed.

          Section 13.04.     Notice of Redemption.
                             -------------------- 

          Notice of redemption shall be given by the Company, or at the
Company's request, by the Trustee in the name and at the expense of the Company,
not less than 30 days and not more than 60 days prior to the Redemption Date to
the Holders of Debt Securities of any series to be redeemed in whole or in part
pursuant to this Article Thirteen, in the manner provided in Section 1.05.  Any
notice so given shall be conclusively presumed to have been duly given, whether
or not the Holder receives such notice.  Failure to give such notice, or any
defect in such notice to the Holder of any Debt Security of a series designated
for redemption, in whole or in part, shall not affect the sufficiency of any
notice of redemption with respect to the Holder of any other Debt Security of
such series.

          All notices of redemption shall state:

          (1)  the Redemption Date,

          (2)  the Redemption Price,

          (3) that Debt Securities of such series are being redeemed by the
     Company pursuant to provisions contained in this Indenture or the terms of
     the Debt Securities of such series or a supplemental indenture establishing
     such series, if such be the case, together with a brief statement of the
     facts permitting such redemption,

                                       64

          (4)  if less than all Outstanding Debt Securities of any series are to
     be redeemed, the identification (and, in the case of partial redemption,
     the principal amounts) of the particular Debt Securities to be redeemed,

          (5) that on the Redemption Date the Redemption Price will become due
     and payable upon each such Debt Security to be redeemed, and that interest
     thereon, if any, shall cease to accrue on and after said date,

          (6) the Place or Places of Payment where such Debt Securities are to
     be surrendered for payment of the Redemption Price, and

          (7) that the redemption is for a sinking fund, if such is the case.

          Section 13.05.     Deposit of Redemption Price.
                             --------------------------- 

          On or prior to the Redemption Date for any Debt Securities, the
Company shall deposit with the Trustee or with a Paying Agent (or, if the
Company is acting as its own Paying Agent, segregate and hold in trust as
provided in Section 12.04) an amount of money sufficient to pay the Redemption
Price of such Debt Securities or any portions thereof which are to be redeemed
on that date.

          Section 13.06.     Debt Securities Payable on Redemption Date.
                             ------------------------------------------ 

          Notice of redemption having been given as aforesaid, any Debt
Securities so to be redeemed shall, on the Redemption Date, become due and
payable at the Redemption Price  and from and after such date (unless the
Company shall default in the payment of the Redemption Price) such Debt
Securities shall cease to bear interest.  Upon surrender of any such Debt
Security for redemption in accordance with said notice, such Debt Security shall
be paid by the Company at the Redemption Price; provided, however, that, unless
                                                --------  -------              
otherwise specified as contemplated by Section 3.01, installments of interest on
Registered Securities which have a Stated Maturity on or prior to the Redemption
Date for such Debt Securities shall be payable according to the terms of such
Debt Securities and the provisions of Section 3.07.

          If any Debt Security called for redemption shall not be so paid upon
surrender thereof for redemption, the principal (and premium, if any) shall,
until paid, bear interest from the Redemption Date at the rate prescribed
therefor in the Debt Security.

          Section 13.07.     Dent Securities Redeemed in Part.
                             -------------------------------- 

          Any Debt Security which is to be redeemed only in part shall be
surrendered at the Corporate Trust Office or such other office or agency of the
Company as is specified pursuant to Section 3.01 with, if the Company, the
Security Registrar or the Trustee so requires, due endorsement by, or a written
instrument of transfer in form satisfactory to the Company, the Security
Registrar and the Trustee duly executed by, the Holder thereof or his attorney
duly authorized in writing, and the Company shall execute, and the Trustee shall
authenticate and deliver to the Holder of such Debt Security without service
charge, a new Debt Security or Debt Securities of the same series, of like tenor
and form, of any authorized denomination as requested by such Holder in
aggregate principal amount equal to and in exchange for the unredeemed portion
of the principal of the Debt Security so surrendered.  In the case of a Debt
Security providing appropriate space for such notation, at the option of the
Holder thereof, the Trustee, in lieu of delivering a new Debt Security or Debt
Securities as aforesaid, may make a notation on such Debt Security of the
payment of the redeemed portion thereof.

pursuant to Section 3.01 for Debt Securities of such series.

          The minimum amount of any sinking fund payment provided for by the

          In lieu of making all or any part of a mandatory sinking fund payment
with respect to any Debt Securities of a series in cash, the Company may at its
option, at any time no more than sixteen months and no less than 45 days prior
to the date on which such sinking fund payment is due, deliver to the Trustee
Debt Securities of such series theretofore purchased or otherwise acquired by
the Company, except Debt Securities of such series which have been redeemed
through the application of mandatory sinking fund payments pursuant to the terms
of the Debt Securities of such series, accompanied by a Company Order
instructing the Trustee to credit such obligations and stating that the Debt
Securities of such series were originally issued by the Company by way of bona
fide sale or other negotiation for value, provided that such Debt Securities
                                          --------                          
shall not have been previously so credited.  Such Debt Securities shall be
received and credited for such purpose by the Trustee at the Redemption Price
specified in such Debt Securities for redemption through operation of the
sinking fund and the amount of such mandatory sinking fund payment shall be
reduced accordingly.
          
          Section 14.03.     Redemption of Debt Securities for Sinking Fund.
                             ---------------------------------------------- 

          Not less than 60 days prior to each sinking fund payment date for any
series of Debt Securities (unless a shorter period shall be satisfactory to the
Trustee), the Company will deliver to the Trustee an Officers' Certificate
specifying the amount of the next ensuing sinking fund payment for that series
pursuant to the terms of that series, the portion thereof, if any, which is to
be satisfied by payment of cash and the portion thereof, if any, which is to be
satisfied by delivering and crediting Debt Securities of such series pursuant to
Section 14.02 and whether the Company intends to exercise its rights to make a
permitted optional sinking fund payment with respect to such series.  Such
certificate shall be irrevocable and upon its delivery the Company shall be
obligated to make the cash payment or payments therein referred to, if any, on
or before the next succeeding sinking fund payment date.  In the case of the
failure of the Company to deliver such certificate, the sinking fund payment due
on the next succeeding sinking fund payment date for such series shall be paid
entirely in cash and shall be sufficient to redeem the principal amount of the
Debt Securities of such series subject to a mandatory sinking fund payment
without the right to deliver or credit Debt Securities as provided in Section
14.02 and without the right to make any optional sinking fund payment with
respect to such series at such time.

          Any sinking fund payment or payments (mandatory or optional) made in
cash plus any unused balance of any preceding sinking fund payments made with
respect to the Debt Securities of any particular series shall be applied by the
Trustee (or by the Company if the Company is acting as its own Paying Agent) on
the sinking fund payment date on which such payment is made (or, if such payment
is made before a sinking fund payment date, on the sinking fund payment date
immediately following the date of such payment) to the redemption of Debt
Securities of such series at the Redemption Price specified in such Debt
Securities with respect to the sinking fund.  Any sinking fund moneys not so
applied or allocated by the Trustee (or by the Company if the Company is acting
as its own Paying Agent) to the redemption of Debt Securities shall be added to
the next sinking fund payment received by the Trustee (or if the Company is
acting as its own Paying Agent, segregated and held in trust as provided in
Section 12.04) for such series and, together with such payment (or such amount
so segregated) shall be applied in accordance with the provisions of this
Section.  Any and all sinking fund moneys with respect to the Debt Securities of
any particular series held by the Trustee (or if the Company is acting as its
own Paying Agent, segregated and held in trust as provided in Section 12.04) on
the last sinking fund payment date with respect to Debt Securities of such
series and not held for the payment or redemption of particular Debt Securities
of such series shall be applied by the Trustee (or by the Company if the Company
is acting as its own Paying Agent), together with other moneys, if necessary, to
be deposited (or segregated) sufficient for the purpose, to the payment of the
principal of the Debt Securities of such series at Maturity.

          The Trustee shall select or cause to be selected the Debt Securities
to be redeemed upon such sinking fund payment date in the manner specified in
Section 13.03 (unless otherwise specified pursuant to Section 3.01) and the
Company shall cause notice of the redemption thereof to be given in the manner
provided in Section 13.04.  Such notice having been duly given, the redemption
of such Debt Securities shall be made upon the terms and in the manner stated in
Section 13.06.

          On or before each sinking fund payment date, the Company shall pay to
the Trustee (or, if the Company is acting as its own Paying Agent, the Company
shall segregate and hold in trust as provided in Section 12.04) in cash a sum,
equal to the principal and any interest accrued to the Redemption Date for Debt
Securities or portions thereof to be redeemed on such sinking fund payment date
pursuant to this Section.

          Neither the Trustee nor the Company shall redeem any Debt Securities
of a series with sinking fund moneys or mail any notice of redemption of Debt
Securities of such series by operation of the sinking fund for such series
during the continuance of a default in payment of interest, if any, on any Debt
Securities of such series or of any Event of Default (other than an Event of
Default occurring as a consequence of this paragraph) with respect to the Debt
Securities of such series, except that if the notice of redemption shall have
been provided in accordance with the provisions hereof, the Trustee (or the
Company, if the Company is then acting as its own Paying Agent) shall redeem
such Debt Securities if cash sufficient for that purpose shall be deposited with
the Trustee (or segregated by the Company) for that purpose in accordance with
the terms of this Article.  Except as aforesaid, any moneys in the sinking fund
for such series at the time when any such default or Event of Default shall
occur and any moneys thereafter paid into such sinking fund shall, during the
continuance of such default or Event of Default, be held as security for the
payment of the Debt Securities of such series; provided, however, that in case
                                               --------  -------              
such default or Event of Default shall have been cured or waived as provided
herein, such moneys shall thereafter be applied on or prior to the next sinking
fund payment date for the Debt Securities of such series on which such moneys
may be applied pursuant to the provisions of this Section.

                                   DEFEASANCE

          Section 15.01.  Applicability of Article.
                          ------------------------ 

          If, pursuant to Section 3.01, provision is made for the defeasance of
Debt Securities of a series, then the provisions of this Article shall be
applicable except as otherwise specified pursuant to Section 3.01 for Debt
Securities of such series.

          Section 15.02.  Defeasance Upon Deposit of Moneys or U.S. Government
                          ----------------------------------------------------
Obligations.
- ----------- 

          At the Company's option, either (a) the Company shall be deemed to
have been Discharged (as defined below) from its obligations with respect to
Debt Securities of any series ("legal defeasance option") or (b) the Company
shall cease to be under any obligation to comply with any term, provision or
condition set forth in Section 10.01 with respect to Debt Securities of any
series (and, if so specified pursuant to Section 3.01, any other obligation of
the Company or restrictive covenant added for the benefit of such series
pursuant to Section 3.01) ("covenant defeasance option") at any time after the
applicable conditions set forth below have been satisfied:

          (1) the Company shall have deposited or caused to be deposited
     irrevocably with the Trustee as trust funds in trust, specifically pledged
     as security for, and dedicated solely to, the benefit of the Holders of the
     Debt Securities of such series (i) money in an amount, or (ii) U.S.
     Government Obligations (as defined below) which through the payment of
     interest and principal in respect thereof in accordance with their terms
     will provide, not later than one day before the due date of any payment,
     money in an amount, or (iii) a combination of (i) and (ii), sufficient, in
     the opinion (with respect to (i) and (ii)) of a nationally recognized firm
     of independent public accountants expressed in a written certification
     thereof delivered to the Trustee, to pay and discharge each installment of
     principal (including any mandatory sinking fund payments) of and premium,
     if any, and interest on, the Outstanding Debt Securities of such series on
     the dates such installments of interest or principal and premium are due;

          (2) such deposit shall not cause the Trustee with respect to the Debt
     Securities of that series to have a conflicting interest as defined in
     Section 6.08 and for purposes of the Trust Indenture Act with respect to
     the Debt Securities of any series;

          (3) such deposit will not result in a breach or violation of, or
     constitute a default under, this Indenture or any other agreement or
     instrument to which the Company is a party or by which it is bound;

          (4) if the Debt Securities of such series are then listed on any
     national securities exchange, the Company shall have delivered to the
     Trustee an Opinion of Counsel or a letter or other document from such
     exchange to the effect that the Company's exercise of its option under this
     Section would not cause such Debt Securities to be delisted;

          (5) no Event of Default or event (including such deposit) which, with
     notice or lapse of time or both, would become an Event of Default with
     respect to the Debt Securities of such series shall have occurred and be
     continuing on the date of such deposit and, with respect to the legal
     defeasance option only, no Event of Default under Section 5.01(5) or
     Section 5.01(6) or event which with the giving of notice or lapse of time,
     or both, would become an Event of

                                       68
<PAGE>
 
     Default under Section 5.01(5) or Section 5.01(6) shall have occurred and be
     continuing on the 91st day after such date; and

          (6) the Company shall have delivered to the Trustee an Opinion of
     Counsel or a ruling from the Internal Revenue Service to the effect that
     the Holders of the Debt Securities of such series will not recognize
     income, gain or loss for Federal income tax purposes as a result of such
     deposit, defeasance or Discharge.

Notwithstanding the foregoing, if the Company exercises its covenant defeasance
option and an Event of Default under Section 5.01(5) or Section 5.01(6) or event
which with the giving of notice or lapse of time, or both, would become an Event
of Default under Section 5.01(5) or Section 5.01(6) shall have occurred and be
continuing on the 91st day after the date of such deposit, the obligations of
the Company referred to under the definition of covenant defeasance option with
respect to such Debt Securities shall be reinstated.  Money and securities held
in trust pursuant to a legal defeasance shall not be subject to Article Sixteen.

          "Discharged" means that the Company shall be deemed to have paid and
discharged the entire indebtedness represented by, and obligations under, the
Debt Securities of such series and to have satisfied all the obligations under
this Indenture relating to the Debt Securities of such series (and the Trustee,
at the expense of the Company, shall execute proper instruments acknowledging
the same), except (A) the rights of Holders of Debt Securities of such series to
receive, from the trust fund described in clause (1) above, payment of the
principal of (and premium, if any) and interest on such Debt Securities when
such payments are due, (B) the Company's obligations with respect to the Debt
Securities of such series under Sections 3.04, 3.05, 3.06, 12.03 and 15.03 and
(C) the rights, powers, trusts, duties and immunities of the Trustee hereunder.

          "U.S. Government Obligations" means securities that are (a) direct
obligations of the United States of America for the timely payment of which its
full faith and credit is pledged or (b) obligations of a Person controlled or
supervised by and acting as an agency or instrumentality of the United States of
America the timely payment of which is unconditionally guaranteed as a full
faith and credit obligation by the United States of America, which, in either
case, are not callable or redeemable at the option of the issuer thereof, and
shall also include a depository receipt issued by a bank (as defined in Section
3(a)(2) of the Securities Act), as custodian with respect to any such U.S.
Government Obligation or a specific payment of principal of or interest on any
such U.S. Government Obligation held by such custodian for the account of the
holder of such depository receipt; provided, that (except as required by law)
such custodian is not authorized to make any deduction from the amount payable
to the holder of such depository receipt from any amount received by the
custodian in respect of the U.S. Government Obligation or the specific payment
of principal of or interest on the U.S. Government Obligation evidenced by such
depository receipt.

          All moneys and U.S. Government Obligations deposited with the Trustee
pursuant to Section 15.02 in respect of Debt Securities of a series shall be
held in trust and applied by it, in accordance with the provisions of such Debt
Securities and this Indenture, to the payment, either directly or through any
Paying Agent (including the Company acting as its own Paying Agent) as the
Trustee may determine, to the Holders of such Debt Securities, of all sums due
and to become due thereon for principal (and premium, if any) and interest, if
any, but such money need not be segregated from other funds except to the extent
required by law.

                          -------------------- 

          The Trustee and any Paying Agent shall promptly pay or return to the
Company upon Company Request any moneys or U.S. Government Obligations held by
them at any time that are not required for the payment of the principal of (and
premium, if any) and interest on the Debt Securities of any series for which
money or U.S. Government Obligations have been deposited pursuant to Section
15.02.

          The provisions of the last paragraph of Section 12.04 shall apply to
any money held by the Trustee or any Paying Agent under this Article that
remains unclaimed for two years after the Maturity of any series of Debt
Securities for which money or U.S. Government Obligations have been deposited
pursuant to Section 15.02.

          Section 16.01.  Agreement to Subordinate.
                          ------------------------ 

          The Company, for itself, its successors and assigns, covenants and
agrees, and each Holder of Debt Securities by his acceptance thereof, likewise
covenants and agrees, that the payment of the principal of (and premium, if any)
and interest on each and all of the Debt Securities is hereby expressly
subordinated, to the extent and in the manner hereinafter set forth, in right of
payment to the prior payment in full of all Senior Indebtedness.

                          --------------------------------------------
Reorganization; Subrogation of Debt Securities.
- ---------------------------------------------- 

          Upon any distribution of assets of the Company upon any dissolution,
winding up, liquidation or reorganization of the Company, whether in bankruptcy,
insolvency, reorganization of the Company or receivership proceedings upon an
assignment for the benefit of creditors or any other marshalling of the assets
and liabilities of the Company or otherwise (subject to the power of a court of
competent jurisdiction to make other equitable provision reflecting the rights
conferred in this Indenture upon the Senior Indebtedness and the holders thereof
with respect to the Debt Securities and the Holders thereof by a plan of
reorganization under applicable bankruptcy law):

          (a) the holders of all Senior Indebtedness shall be entitled to
     receive payment in full of the principal thereof (and premium, if any) and
     interest due thereon before the Holders of the Debt Securities are entitled
     to receive any payment upon the principal (and premium, if any) or interest
     on indebtedness evidenced by the Debt Securities; and

          (b) any payment or distribution of the Company of any kind or
     character, whether in cash, property or securities, to which the Holders of
     the Debt Securities or the Trustee would be entitled except for the
     provisions of this Article Sixteen shall be paid by the liquidating trustee
     or agent or other person making such payment or distribution, whether a
     trustee in bankruptcy, a receiver or liquidating trustee or otherwise,
     directly to the holders of Senior Indebtedness or their representative or
     representatives or to the trustee or trustees under any indenture under
     which any instruments evidencing any of such Senior Indebtedness may have
     been issued, ratably according to the aggregate amounts remaining unpaid on
     account of the principal of (and

                                       70
<PAGE>
 
     premium, if any) and interest on the Senior Indebtedness held or
     represented by each, to the extent necessary to make payment in full of all
     Senior Indebtedness remaining unpaid, after giving effect to any concurrent
     payment or distribution to the holders of such Senior Indebtedness; and

          (c) in the event that, notwithstanding the foregoing, any payment or
     distribution of assets of the Company of any kind or character, whether in
     cash, property or securities, shall be received by the Trustee or the
     Holders of the Debt Securities before all Senior Indebtedness is paid in
     full, such payment or distribution shall be paid over, upon written notice
     to the Trustee, to the holder of such Senior Indebtedness or their
     representative or representatives or to the trustee or trustees under any
     indenture under which instrument evidencing any of such Senior Indebtedness
     may have been issued, ratably as aforesaid, for application to payment of
     all Senior Indebtedness remaining unpaid until all such Senior Indebtedness
     shall have been paid in full, after giving effect to any concurrent payment
     or distribution to the holders of such Senior Indebtedness.

          Subject to the payment in full of all Senior Indebtedness, the Holders
of the Debt Securities shall be subrogated to the rights of the holders of
Senior Indebtedness to receive payments or distributions of cash, property or
securities of the Company applicable to Senior Indebtedness until the principal
of (and premium, if any) and interest on the Debt Securities shall be paid in
full and no such payments or distributions to the holders of such Senior
Indebtedness to which the Holders of Debt Securities or the Trustee would be
entitled except for the provisions of this Article or payments over, pursuant to
the provisions of this Article, to the holders of such Senior Indebtedness by
the Holders of the Debt Securities or on their behalf or by the Trustee shall,
as between the Company, its creditors other than the holders of Senior
Indebtedness and the Holders of the Debt Securities, be deemed to be a payment
by the Company to or on account of Senior Indebtedness.  It is understood that
the provisions of this Article Sixteen are and are intended solely for the
purpose of defining the relative rights of the Holders of the Debt Securities,
on the one hand, and the holders of the Senior Indebtedness, on the other hand.
Nothing contained in this Article Sixteen or elsewhere in this Indenture or in
the Debt Securities is intended to or shall impair, as between the Company, its
creditors other than the holders of Senior Indebtedness, and the Holders of the
Debt Securities, the obligation of the Company, which is unconditional and
absolute, to pay to the Holders of the Debt Securities the principal of (and
premium, if any) and interest on the Debt Securities as and when the same shall
become due and payable in accordance with their terms, or to affect the relative
rights of the Holders of the Debt Securities and creditors of the Company other
than the holders of Senior Indebtedness, nor shall anything herein or in the
Debt Securities prevent the Trustee or the Holder of any Debt Security from
exercising all remedies otherwise permitted by applicable law upon default under
this Indenture, subject to the rights, if any, under this Article Sixteen of the
holders of Senior Indebtedness in respect of cash, property or securities of the
Company received upon the exercise of any such remedy.  Upon any payment or
distribution of assets of the Company referred to in this Article Sixteen, the
Trustee, subject to the provisions of Section 6.02, shall be entitled to rely
upon a certificate of the liquidating trustee or agent or other person making
any distribution to the Trustee for the purpose of ascertaining the Persons
entitled to participate in such distribution, the holders of Senior Indebtedness
and other indebtedness of the Company, the amount thereof or payable thereon,
the amount or amounts paid or distributed thereon and all other facts pertinent
to this Article Sixteen.

          The Trustee, however, shall not be deemed to owe any fiduciary duty to
the holders of Senior Indebtedness.  The Trustee shall not be liable to any such
holder if it shall pay or distribute to or on behalf of Holders of Debt
Securities or the Company moneys or assets to which any holder of Senior
Indebtedness shall be entitled by virtue of this Article Sixteen.

     If the Trustee or any Holder of Debt Securities does not file a proper
claim or proof of debt in the form required in any proceeding referred to above
prior to 30 days before the expiration of the time to file such claim in such
proceeding, then the holder of any Senior Indebtedness is hereby authorized, and
has the right, to file an appropriate claim or claims for or on behalf of such
Holder of Debt Securities.

Senior Indebtedness.
- ------------------- 

          No payment by the Company on account of principal (or premium, if
any), sinking funds or interest on the Debt Securities shall be made after any
applicable grace period unless full payment of amounts then due for principal,
premium, if any, sinking funds, and interest on Senior Indebtedness has been
made or duly provided for.

          Section 16.04.  Payments on Debt Securities Permitted.
                          ------------------------------------- 

          Nothing contained in this Indenture or in any of the Debt Securities
shall (a) affect the obligation of the Company to make, or prevent the Company
from making, at any time except as provided in Sections 16.02 and 16.03,
payments of principal (and premium, if any) or interest of the Debt Securities
or (b) prevent the application by the Trustee of any moneys deposited with it
hereunder to the payment of or on account of the principal of (and premium, if
any) or interest on the Debt Securities, unless the Trustee shall have received
at its Corporate Trust Office written notice of any event prohibiting the making
of such payment more than two Business Days prior to the date fixed for such
payment.

                          ---------------------------------------------
Subordination.
- ------------- 

          Each Holder of Debt Securities by his acceptance thereof authorizes
and directs the Trustee on his behalf to take such action as may be necessary or
appropriate to effectuate the subordination as provided in this Article Sixteen
and appoints the Trustee his attorney-in-fact for any and all such purposes.

          Section 16.06.  Notices to Trustee.
                          ------------------ 

          The Company shall give prompt written notice to the Trustee of any
fact known to the Company which would prohibit the making of any payment to or
by the Trustee in respect of the Debt Securities.  Failure to give such notice
shall not affect the subordination of the Debt Securities to Senior
Indebtedness.  Notwithstanding the provisions of this Article or any other
provisions of this Indenture, neither the Trustee nor any Paying Agent (other
than the Company) shall be charged with knowledge of the existence of any Senior
Indebtedness or of any event which would prohibit the making of any payment of
moneys to or by the Trustee or such Paying Agent, unless and until the Trustee
of such Paying Agent shall have received (in the case of the Trustee, at its
Corporate Trust Office) written notice thereof from the Company or from the
holder of any Senior Indebtedness or from the trustee for any such holder,
together with proof satisfactory to the Trustee of such holding of Senior
Indebtedness or of the authority of such trustee; provided, however, that if at
least two Business Days prior to the date upon which by the terms hereof any
such moneys may become payable for any purpose (including, without limitation,
the payment of either the principal (and premium, if any) or interest on any
Debt Security) the Trustee shall not have received with respect to such moneys
the notice provided for in this Section 16.06, then, anything herein contained
to the contrary notwithstanding, the Trustee shall have full power and authority
to receive such moneys and to apply the same to the purpose for which they were
received, and shall not be affected by any notice to the contrary, which may be
received by it within two Business Days prior

                                       72

to such date.  The Trustee shall be entitled to rely on the delivery to it of a
written notice by a Person representing himself to be a holder of Senior
Indebtedness (or a trustee on behalf of such holder) to establish that such a
notice has been given by a holder of Senior Indebtedness or a trustee on behalf
of any such holder.  In the event that the Trustee determines in good faith that
further evidence is required with respect to the right of any Person as a holder
of Senior Indebtedness to participate in any payment or distribution pursuant to
this Article Sixteen, the Trustee may request such person to furnish evidence to
the reasonable satisfaction of the Trustee as to the amount of Senior
Indebtedness held by such Person, the extent to which such Person is entitled to
participate in such payment or distribution and any other facts pertinent to the
rights of such Person under this Article Sixteen and, if such evidence is not
furnished, the Trustee may defer any payment to such person pending judicial
determination as to the right of such person to receive such payment.

          Section 16.07.  Trustee as Holder of Senior Indebtedness.
                          ---------------------------------------- 

          The Trustee in its individual capacity shall be entitled to all the
rights set forth in this Article Sixteen in respect of any Senior Indebtedness
at any time held by it to the same extent as any other holder of Senior
Indebtedness and nothing in this Indenture shall be construed to deprive the
Trustee of any of its rights as such holder.

          Nothing in this Article shall apply to claims, of, or payments to, the
Trustee under or pursuant to Section 6.07.

          Section 16.08.  Modification of Terms of Senior Indebtedness.
                          -------------------------------------------- 

          Any renewal or extension of the time of payment of any Senior
Indebtedness or the exercise by the holders of Senior Indebtedness of any of
their rights under any instrument creating or evidencing Senior Indebtedness,
including, without limitation, the waiver of default thereunder, may be made or

          Upon any payment or distribution of assets of the Company referred to

shall be entitled to rely upon any order or decree entered by any court of
competent jurisdiction in which each insolvency, bankruptcy, receivership,

proceeding is pending, or a certificate of the trustee in bankruptcy,
liquidating trustee, custodian, receiver, assignee for the benefit of creditors,

Holder of Debt Securities by his acceptance thereof, likewise covenants and
agrees, that the payment of the principal of (and premium, if any) and interest

                               ARTICLE SEVENTEEN

                                   CONVERSION

          Section 17.01.     Applicability; Conversion Privilege.
                             ----------------------------------- 

          Except as otherwise specified pursuant to Section 3.01 for Debt
Securities of any series, the provisions of this Article Seventeen shall be
applicable to any Debt Securities that are convertible into Common Stock or
Preferred Stock.  If so provided pursuant to Section 3.01 with respect to the
Debt Securities of any series, the Holder of a Debt Security of such series
shall have the right, at such Holder's option, to convert, in accordance with
the terms of such series of Debt Securities and this Article Seventeen, all or
any part (in a denomination of, unless otherwise specified pursuant to Section
3.01 with respect to Securities of such series, $1,000 in principal amount or
any integral multiple thereof) of such Debt Security into shares of Common Stock
or Preferred Stock, as the case may be, or, as to any Debt Securities called for
redemption, at any time prior to the time and date fixed for such redemption
(unless the Company shall default in the payment of the Redemption Price, in
which case such right shall not terminate at such time and date).

          Section 17.02.     Conversion Procedure; Conversion Price; Fractional
                             --------------------------------------------------
Shares.
- ------ 

          (a) Each Debt Security to which this Article is applicable shall be
convertible at the office of the Conversion Agent, and at such other place or
places, if any, specified in pursuant to Section 3.01 with respect to the Debt
Securities of such series, into fully paid and nonassessable shares (calculated
to the nearest 1/100th of a share) of Common Stock or Preferred Stock, as the
case may be. The Debt Securities will be converted into shares of Common Stock
or Preferred Stock, as the case may be, at the Conversion Price therefor.  No
payment or adjustment shall be made in respect of dividends on the Common Stock
or Preferred Stock or accrued interest on a converted Debt Security except as
described in Section 17.09.  The Company may, but shall not be required, in
connection with any conversion of Debt Securities, to issue a fraction of a
share of Common Stock or Preferred Stock and, if the Company shall determine not
to issue any such fraction, the Company shall, subject to Section 17.03(4), make
a cash payment (calculated to the nearest cent) equal to such fraction
multiplied by the Closing Price of the Common Stock or Preferred Stock, as the
case may be, on the last Trading Day prior to the date of conversion.

          (b) Before any Holder of a Debt Security shall be entitled to convert
the same into Common Stock or Preferred Stock, such Holder shall surrender such
Debt Security duly endorsed to the Company or in blank, at the office of the
Conversion Agent, or at such other place or places, if any, specified pursuant
to Section 3.01 (in the case of Registered Securities) and at an office of the
Conversion Agent, and shall give written notice to the Company at said office or
place that he elects to convert the same and shall state in writing therein the
principal amount of Debt Securities to be converted and the name or names (with
addresses) in which he wishes the certificate or certificates for Common Stock
or Preferred Stock, as the case may be, to be issued; provided, however, that no
Debt Security or portion

                                       75
<PAGE>
 
thereof shall be accepted for conversion unless the principal amount of such
Debt Security or such portion, when added to the principal amount of all other
Debt Securities or portions thereof then being surrendered by the Holder thereof
for conversion, exceeds the then effective Conversion Price with respect
thereto.  If more than one Debt Security shall be surrendered for conversion at
one time by the same Holder, the number of full shares of Common Stock or
Preferred Stock, as the case may be, which shall be deliverable upon conversion
shall be computed on the basis of the aggregate principal amount of the Debt
Securities (or specified portions thereof to the extent permitted thereby) so
surrendered. Subject to the next succeeding sentence, the Company will, as soon
as practicable thereafter, issue and deliver at said office or place to such
Holder of a Debt Security, or to his nominee or nominees, certificates for the
number of full shares of Common Stock or Preferred Stock, as the case may be, to
which he shall be entitled as aforesaid, together, subject to the last sentence
of paragraph (a) above, with cash in lieu of any fraction of a share to which he
would otherwise be entitled.  The Company shall not be required to deliver
certificates for shares of Common Stock or Preferred Stock while the stock
transfer books for such stock or the Security Register are duly closed for any
purpose, but certificates for shares of Common Stock or Preferred Stock, as the
case may be, shall be issued and delivered as soon as practicable after the
opening of such books or Security Register.  A Debt Security shall be deemed to
have been converted as of the close of business on the date of the surrender of
such Debt Security for conversion as provided above, and the Person or Persons
entitled to receive the Common Stock or Preferred Stock, as the case may be,
issuable upon such conversion shall be treated for all purposes as the record
Holder or Holders of such Common Stock or Preferred Stock as of the close of
business on such date.  In case any Debt Security shall be surrendered for
partial conversion, the Company shall execute and the Trustee shall authenticate
and deliver to or upon the written order of the Holder of the Debt Securities so
surrendered, without charge to such Holder (subject to the provisions of Section
17.08), a new Debt Security or Securities in authorized denominations in an
aggregate principal amount equal to the unconverted portion of the surrendered
Debt Security.

          Section 17.03.     Adjustment of Conversion Price for Common Stock.
                             ----------------------------------------------- 

          The Conversion Price with respect to any Debt Security which is
convertible into Common Stock shall be adjusted from time to time as follows:

          (1) In case the Company shall, at any time or from time to time while
     any of such Debt Securities are outstanding, (i) pay a dividend in shares
     of its Common Stock to holders of Common Stock, (ii) combine its
     outstanding shares of Common Stock into a smaller number of shares of
     Common Stock, (iii) subdivide its outstanding shares of Common Stock into a
     greater number of shares of Common Stock or (iv) make a distribution in
     shares of Common Stock to holders of Common Stock, then the Conversion
     Price in effect immediately before such action shall be adjusted so that
     the Holders of such Debt Securities, upon conversion thereof into Common
     Stock immediately following such event, shall be entitled to receive the
     kind and amount of shares of capital stock of the Company which they would
     have owned or been entitled to receive upon or by reason of such event if
     such Debt Securities had been converted immediately before the record dated
     (or, if no record date, the effective date) for such event. An adjustment
     made pursuant to this Section 17.03(1) shall become effective retroactively
     immediately after the record date in the case of a dividend or distribution
     and shall become effective retroactively immediately after the effective
     date in the case of a subdivision or combination.  For the purposes of this
     Section 17.03(1), each Holder of Debt Securities shall be deemed to have
     failed to exercise any right to elect the kind or amount of securities
     receivable upon the payment of any such dividend, subdivision, combination
     or distribution (provided that if the kind or amount of securities
     receivable upon such dividend, subdivision, combination or distribution is
     not the same for each nonelecting share, then the kind and amount of
     securities or

                                       76
<PAGE>
 
     other property receivable upon such dividend, subdivision, combination or
     distribution for each nonelecting share shall be deemed to be the kind and
     amount so receivable per share by a plurality of the nonelecting shares).

          (2) In case the Company shall, at any time or from time to time while
     any of such Debt Securities are outstanding, issue rights or warrants to
     all holders of shares of its Common Stock entitling them (for a period
     expiring within 45 days after the record date for such issuance) to
     subscribe for or purchase shares of Common Stock (or securities convertible
     into shares of Common Stock) at a price per share less than the Current
     Market Price of the Common Stock at such record date (treating the price
     per share of the securities convertible into Common Stock as equal to (x)
     the sum of (i) the price for a unit of the security convertible into Common
     Stock and (ii) any additional consideration initially payable upon the
     conversion of such security into Common Stock divided by (y) the number of
     shares of Common Stock initially underlying such convertible security), the
     Conversion Price with respect to such Debt Securities shall be adjusted so
     that it shall equal the price determined by dividing the Conversion Price
     in effect immediately prior to the date of issuance of such rights or
     warrants by a fraction, the numerator of which shall be the number of
     shares of Common Stock outstanding on the date of issuance of such rights
     or warrants plus the number of additional shares of Common Stock offered
     for subscription or purchase (or into which the convertible securities so
     offered are initially convertible), and the denominator of  which shall be
     the number of shares of Common Stock outstanding on the date of issuance of
     securities which the aggregate offering price of the total number of shares
     of securities so offered for subscription or purchase (or the aggregate
     purchase price of the convertible securities so offered plus the aggregate
     amount of any additional consideration initially payable upon conversion of
     such securities into Common Stock) would purchase at such Current Market
     Price of the Common Stock.  Such adjustment shall become effective
     retroactively immediately after the record date for the determination of
     stockholders entitled to receive such rights or warrants.

          (3) In the case the Company shall, at any time or from time to time
     while any of such Debt Securities are outstanding, distribute to all
     holders of shares of its Common Stock (including any such distribution made
     in connection with a consolidation or merger in which the Company is the
     continuing corporation and the Common Stock is not changed or exchanged)
     cash, evidences of its indebtedness, securities or assets (excluding (i)
     regular periodic cash dividends in amounts, if any, determined from time to
     time by the Board of Directors, (ii) dividends payable in shares of Common
     Stock for which adjustment is made under Section 17.03(1) or (iii) rights
     or warrants to subscribe for or purchase securities of the Company
     (excluding those referred to in Section 17.03(2))), then in each such case
     the Conversion Price with respect to such Debt Securities determined by
     dividing the Conversion Price in effect immediately prior to the date of
     such distribution by a fraction, the numerator of which shall be the
     Current Market Price of the Common Stock on the record date referred to
     below, and the denominator of which shall be such Current Market Price of
     the Common Stock less the then fair market value (as determined by the
     Board of Directors of the Company, whose determination shall be conclusive)
     of the portion of the cash or assets or evidences of indebtedness or
     securities so distributed or of such subscription rights or warrants
     applicable to one share of Common Stock (provided that such denominator
     shall never be less than 1.0); provided however, that no adjustment shall
     be made with respect to any distribution of rights to purchase securities
     of the Company if a Holder of Debt Securities would otherwise be entitled
     to receive such rights upon conversion at any time of such Debt Securities
     into Common Stock unless such rights are subsequently redeemed by the
     Company, in which case such redemption shall be treated for purposes of
     this section as a dividend on the Common Stock.  Such adjustment shall
     become effective retroactively

                                       77
<PAGE>
 
     immediately after the record date for the determination of stockholders
     entitled to receive such distribution; and in the event that such
     distribution is not so made, the Conversion Price shall again be adjusted
     to the Conversion Price which would then be in effect if such record date
     had not been fixed.

          (4) The Company shall be entitled to make such additional adjustments
     in the Conversion Price, in addition to those required by subsections
     17.03(1), 17.03(2), and 17.03(03), as shall be necessary in order that any
     dividend or distribution of Common Stock, any subdivision, reclassification
     or combination of shares of Common Stock or any issuance of rights or
     warrants referred to above shall not be taxable to the holders of Common
     Stock for United States Federal income tax purposes.

          (5) In any case in which this Section 17.03 shall require that any
     adjustment be made effective as of or retroactively immediately following a
     record date, the Company may elect to defer (but only for five (5) Trading
     Days following the filing of the statement referred to in Section 17.05)
     issuing to the Holder of any Debt Securities converted after such record
     date the shares of Common Stock and other capital stock of the Company
     issuable upon such conversion over and above the shares of Common Stock and
     other capital stock of the Company issuable upon such conversion on the
     basis of the Conversion Price prior to adjustment; provided, however, that
     the Company shall deliver to such Holder a due bill or other appropriate
     instrument evidencing such Holder's right to receive such additional shares
     upon the occurrence of the event requiring such adjustment.

          (6) All calculations under this Section 17.03 shall be made to the
     nearest cent or one-hundredth of a share of security, with one-half cent
     and 0.005 of a share, respectively, being rounded upward.  Notwithstanding
     any other provision of this Section 17.03, the Company shall not be
     required to make any adjustment of the Conversion Price unless such
     adjustment would require an increase or decrease of at least 1% of such
     price.  Any lessor adjustment shall be carried forward and shall be made at
     the time of and together with the next subsequent adjustment which,
     together with any adjustment or adjustments so carried forward, shall
     amount to an increase or decrease of at least 1% in such price.  Any
     adjustments under this Section 17.03 shall be made successively whenever an
     event requiring such an adjustment occurs.

          (7) In the event that at any time, as a result of an adjustment made
     pursuant to this Section 17.03, the Holder of any Debt Security thereafter
     surrendered for conversion shall become entitled to receive any shares of
     stock of the Company other than shares of Common Stock into which the Debt
     Securities originally were convertible, the Conversion Price of such other
     shares so receivable upon conversion of any such Debt Security shall be
     subject to adjustment from time to time in a manner and on terms as nearly
     equivalent as practicable to the provisions with respect to Common Stock
     contained in subparagraphs (1) through (6) of this Section 17.03, and the
     provisions of Sections 17.01, 17.02 and 17.04 through 17.09 with respect to
     the Common Stock shall apply on like or similar terms to any such other
     shares and the determination of the Board of Directors as to any such
     adjustment shall be conclusive.

          (8) No adjustment shall be made pursuant to this Section:  (i) if the
     effect thereof would be to reduce the Conversion Price below the par value
     (if any) of the Common Stock or (ii)  subject to 17.03(5) hereof, with
     respect to any Debt Security that is converted prior to the time such
     adjustment otherwise would be made.

           Section 17.04.     Consolidation or Merger of the Company.
                              -------------------------------------- 

          In case of either (a) any consolidation or merger to which the Company
is a party, other than a merger or consolidation in which the Company is the
surviving or continuing corporation and which does not result in a
reclassification of, or change (other than a change in par value or from par
value to no par value or from no par value to par value, as a result of a
subdivision or combination) in, outstanding shares of Common Stock or (b) any
sale or conveyance of all or substantially all of the property and assets of the
Company to another Person, then each Debt Security then outstanding shall be
convertible from and after such merger, consolidation, sale or conveyance of
property and assets into the kind and amount of shares of stock or other
securities and property (including cash) receivable upon such consolidation,
merger, sale or conveyance by a holder of the number of shares of Common Stock
into which such Debt Securities would have been converted immediately prior to
such consolidation, merger, sale or conveyance, subject to adjustments which
shall be as nearly equivalent as may be practicable to the adjustments provided
for in this Article Seventeen (and assuming such holder of Common Stock failed
to exercise his rights of election, if any, as to the kind or amount of
securities, cash or other property (including cash) receivable upon such
consolidation, merger, sale or conveyance (provided that, if the kind or amount
of securities, cash or other property (including cash) receivable upon such
consolidation, merger, sale or conveyance is not the same for each nonelecting
share, then the kind and amount of securities, cash or other property (including
cash) receivable upon such consolidation, merger, sale or conveyance for each
nonelecting share shall be deemed to be the kind and amount so receivable per
share by a plurality of the nonelecting shares or securities)).  The Company
shall not enter into any of the transactions referred to in clause (a) or (b) of
the preceding sentence unless effective provision shall be made so as to give
effect to the provisions set forth in this Section 17.04.  The provisions of
this Section 17.04 shall apply similarly to successive consolidations, mergers,
sales or conveyances.

           Section 17.05.     Notice of Adjustment.
                              -------------------- 

          Whenever an adjustment in the Conversion Price with respect to a
series of Debt Securities is required:

          (1) the Company shall forthwith place on file with the Trustee and any
     Conversion Agent for such Securities a certificate of the Treasurer of the
     Company, stating the adjusted Conversion Price determined as provided
     herein and setting forth in reasonable detail such facts as shall be
     necessary to show the reason for and the manner of computing such
     adjustment, such certificate to be conclusive evidence that the adjustment
     is correct; and

          (2) a notice stating that the Conversion Price has been adjusted and
     setting forth the adjusted Conversion Price shall forthwith be given by the
     Company, or at the Company's request, by the Trustee in the name and at the
     expense of the Company, in the manner provided in Section 1.05.  Any notice
     so given shall be conclusively presumed to have been duly given, whether or
     not the Holder receives such notice.

          Section 17.06.     Notice in Certain Events.
                             ------------------------ 

          In case:
          ------- 

          (1) of a consolidation or merger to which the Company is a party and
     for which approval of any stockholders of the Company is required, or of
     the sale or conveyance to another Person or entity or group of Persons or
     entities acting in concert as a partnership, limited

                                       79
<PAGE>
 
     partnership, syndicate or other group (within the meaning of Rule 13d-3
     under the Securities Exchange Act of 1934, as amended) of all or
     substantially all of the property and assets of the Company; or

          (2) of the voluntary or involuntary dissolution, liquidation or
     winding up of the Company; or

          (3) of any action triggering an adjustment of the Conversion Price
     pursuant to this Article Seventeen;

then, in each case, the Company shall cause to be filed with the Trustee and the
Conversion Agent for the applicable Debt Securities, and shall cause to be
given, to the Holders of record of applicable Debt Securities in the manner
provided in Section 1.05, at least fifteen (15) days prior to the applicable
date hereinafter specified, a notice stating (x) the date on which a record is
to be taken for the purpose of any distribution or grant of rights or warrants
triggering an adjustment to the Conversion Price pursuant to this Article
Seventeen, or, if a record is not to be taken, the date as of which the holders
of record or Common Stock entitled to such distribution, rights or warrants are
to be determined, or (y) the date on which any reclassification, consolidation,
merger, sale, conveyance, dissolution, liquidation or winding up triggering an
adjustment to the Conversion Price pursuant to this Article Seventeen is
expected to become effective, and the date as of which it is expected that
holders of Common Stock of record shall be entitled to exchange their Common
Stock for securities or other property deliverable upon such reclassification,
consolidation, merger, sale, conveyance, dissolution, liquidation or winding up.

          Failure to give such notice or any defect therein shall not affect the
legality or validity of the proceedings described in clause (1), (2), or (3) of
this Section.

          Section 17.07.     Company to Reserve Stock; Registration; Listing.
                             ----------------------------------------------- 

          (a) The Company shall at all times reserve and keep available, free
from preemptive rights, out of its authorized but unissued shares of Common
Stock or Preferred Stock, as the case may be, for the purpose of effecting the
conversion of the Debt Securities, such number of its duly authorized shares of
Common Stock or Preferred Stock, as the case may be, as shall from time to time
be sufficient to effect the conversion of all applicable outstanding Debt
Securities into such Common Stock or Preferred Stock at any time (assuming that,
at the time of the computation of such number of shares or securities, all such
Debt Securities would be held by a single holder); provided, however, that
                                                   -----------------      
nothing contained herein shall preclude the Company from satisfying its
obligations in respect of the conversion of the Debt Securities by delivery of
purchased shares of Common Stock or Preferred Stock, as the case may be, which
are held in the treasury of the Company.  The Company shall from time to time,
in accordance with the laws of its state of incorporation, use its best efforts
to cause the authorized amount of the Common Stock or Preferred Stock, as the
case may be, to be increased if the aggregate of the authorized amount of the
Common Stock or Preferred Stock, as the case may be, remaining unissued and the
issued shares of such Common Stock or Preferred Stock in its treasury (other
than any such shares reserved for issuance in any other connection) shall not be
sufficient to permit the conversion of all Debt Securities.

          (b) If any shares of Common Stock or Preferred Stock, as the case may
be, which would be issuable upon conversion of Debt Securities hereunder require
registration with or approval of any governmental authority before such shares
or securities may be issued upon such conversion, the Company will in good faith
and as expeditiously as possible endeavor to cause such shares or securities to
be duly registered or approved, as the case may be.  The Company will endeavor
to list the shares of

                                       80
<PAGE>
 
Common Stock or Preferred Stock required to be delivered upon conversion of the
Debt Securities prior to such delivery upon the principal national securities
exchange, if any, upon which the outstanding Common Stock or Preferred Stock, as
the case may be, is listed at the time of such delivery.

          Section 17.08.     Taxes on Conversion.
                             ------------------- 

          The Company shall pay any and all documentary, stamp or similar issue
or transfer taxes that may be payable in respect of the issue or delivery of
shares of Common Stock or Preferred Stock, as the case may be, on conversion of
Debt Securities pursuant hereto.  The Company shall not, however, be required to
pay any such tax which may be payable in respect of any transfer involved in the
issue or delivery of shares of Common Stock or Preferred Stock or the portion,
if any, of the Debt Securities which are not so converted in a name other than
that in which the Debt Securities so converted were registered (in case of
Registered Securities), and no such issue or delivery shall be made unless and
until the Person requesting such issue has paid to the Company the amount of
such tax or has established to the satisfaction of the Company that such tax has
been paid.

          Section 17.09.     Conversion After Record Date.
                             ---------------------------- 

          If any Debt Securities are surrendered for conversion subsequent to
the record date preceding an Interest Payment Date but on or prior to such
Interest Payment Date (except Debt Securities called for redemption on a
Redemption Date between such record date and Interest Payment Date), the Holder
of such Debt Securities at the close of business on such record date shall be
entitled to receive the interest payable on such Debt Securities on such
Interest Payment Date notwithstanding the conversion thereof.  Debt Securities
surrendered for conversion during the period from the close of business on any
record date next preceding any Interest Payment Date to the opening of business
on such Interest Payment Date to the opening of business on such Interest
Payment Date shall (except in the case of Debt Securities which have been called
for redemption on a Redemption Date within such period) be accompanied by
payment of an amount equal to the interest payable on such Interest Payment Date
on the Debt Securities being surrendered for conversion.  Except as provided in
this Section 17.09, no adjustments in respect of payments of interest on Debt
Securities surrendered for conversion or any dividends or distributions of

Intermedia Communications Inc.

Tampa, Florida 33619

Ladies and Gentlemen:

     We have acted as counsel to Intermedia Communications Inc., a Delaware
corporation (the "Company"), in connection with its Registration Statement on
Form S-3 (the "Registration Statement") under the Securities Act of 1933, as
amended (the "Act"), pertaining to the issuance by the Company from time to
time, together or separately, and as set forth in the prospectus contained in
the Registration Statement (the "Prospectus") and in one or more supplements to
the Prospectus (each, a "Prospectus Supplement"), of up to $500,000,000
aggregate offering price of (1) debt securities (the "Debt Securities"), which
may be either senior or subordinated and which may be convertible into or
exchangeable for shares of common stock, par value $.01 per share, of the
Company (the "Common Stock"), shares of preferred stock, par value $1.00 per
share, of the Company (the "Preferred Stock"), or other Debt Securities; (2)
Preferred Stock, which may be convertible into or exchangeable for shares of
Common Stock, or shares of Preferred Stock or Debt Securities; (3) depositary
shares ("Depositary Shares") in the event that the Company elects to offer
fractional interests in shares of Preferred Stock, which may be convertible into
or exchangeable for shares of Preferred Stock or Common Stock or Debt
Securities; and (4) Common Stock each in amounts, at prices and on terms to be
determined by market conditions at the time of offering thereof. The Debt
Securities will be issued pursuant to one or more indentures (each, an
"Indenture") in the form filed as an exhibit to the Registration Statement, as
amended or supplemented from time to time, between the Company, as obligor, and
a trustee (each, a "Trustee") chosen by the Company and qualified to act as such
under the Trust Indenture Act of 1939, as amended (the "TIA").

     In so acting, we have examined originals or copies, certified or otherwise
identified to our satisfaction, of the Company's Restated Certificate of
Incorporation (the "Certificate"), the resolutions to be adopted by the Board of
Directors of the Company authorizing the filing of the Registration Statement,
the
<PAGE>
 
Intermedia Communications Inc.

Page 2

Indenture, and such other corporate records, agreements, documents and other
instruments, and such certificates or comparable documents of public officials
and of officers and representatives of the Company, and have made such inquiries
of such officers and representatives, as we have deemed relevant and necessary
as a basis for the opinions hereinafter set forth.

     In such examination, we have assumed the genuineness of all signatures, the
legal capacity of natural persons, the authenticity of all documents submitted
to us as originals, the conformity to original documents of all documents
submitted to us as certified or photostatic copies and the authenticity of the
originals of such latter documents.  As to all questions of fact material to
this opinion that have not been independently established, we have relied upon
certificates or comparable documents of officers and representatives of the
Company.

     Based on the foregoing, and subject to the qualifications stated herein, we
are of the opinion that:

     1.  When (1) the Registration Statement shall have become effective under
the Act, (2) an Indenture shall have been duly executed and delivered by the
Company and a Trustee and duly qualified under the TIA, duly establishing the
terms of particular Debt Securities, and (3) such Debt Securities shall have
been (a) duly authorized, executed, authenticated, issued and delivered against
payment therefor as contemplated by the Indenture and the Registration Statement
and/or the applicable Prospectus Supplement or (b) duly authorized and issued
upon conversion or exchange of Debt Securities or Preferred Stock which, by
their respective terms, are convertible into or exchangeable for Debt
Securities, in each case as contemplated by the Indenture and the Registration
Statement and/or the applicable Prospectus Supplement, and the Company shall
have received any additional consideration which is payable upon such conversion
or exchange, such Debt Securities will constitute binding obligations of the
Company enforceable in accordance with their terms, subject to applicable
bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and
similar laws affecting creditors' rights and remedies generally, and subject, as
to enforceability, to general principles of equity, including principles of
commercial reasonableness, good faith and fair dealing (regardless of whether
enforcement is sought in a proceeding at law or in equity) and except that
rights to indemnification and contribution thereunder and under the Indenture
may be void or limited by federal or state securities laws or public policy
relating thereto.

     2.  When (1) the Registration Statement shall have become under the Act,
and (2) a series of Preferred Stock shall
<PAGE>
 
Intermedia Communications Inc.

Page 3

have been (a) duly authorized, duly established in accordance with the terms of
the Company's Certificate and applicable law, and upon adoption by the Board of
Directors of the Company of one or more resolutions in form and content as
required by applicable law, issued and sold against payment therefor as
contemplated by the Registration Statement and/or the applicable Prospectus
Supplement and by such resolution(s), or (b) duly authorized, duly established
in accordance with the terms of the Company's Certificate and applicable law,
and upon adoption by the Board of Directors of the Company of one or more
resolutions in form and content as required by applicable law, issued upon
conversion or exchange of Debt Securities which, by their terms, are convertible
into or exchangeable for such shares of Preferred Stock, and the Company shall
have received any additional consideration which is payable upon such conversion
or exchange, in each case as contemplated by the Registration Statement and/or
the applicable Prospectus Supplement and by such resolution(s), and assuming for
the purpose of each opinion set forth in this paragraph 2 that the Company shall
have sufficient authorized but unissued shares of Preferred Stock to so issue
such shares of such series of Preferred Stock will be validly issued, fully paid
and non-assessable.

     3.  When (1) the Registration Statement shall have become effective under
the Act, and (2) shares of Common Stock shall have been duly authorized pursuant
to adoption by the Board of Directors of the Company of one or more resolutions
in form and content as required by applicable law, and issued as contemplated by
the Registration Statement and/or the applicable Prospectus Supplement and by
such resolution(s), and assuming for the purpose of each opinion set forth in
this paragraph 3 that the Company shall have sufficient authorized but unissued
shares of Common Stock to so issue such shares of Common Stock, such shares of
Common Stock will be validly issued, fully paid and non-assessable.

     To the extent that the obligations of the Company under any Indenture may
be dependent upon such matters, we assume for purposes of the opinions set forth
herein that each Trustee is duly organized, validly existing and in good
standing under the laws of its jurisdiction of organization; that each Trustee
is duly qualified to engage in the activities contemplated by each Indenture to
which it is a party; that each Indenture has been duly authorized, executed and
delivered by the Trustee party thereto and constitutes the legal, valid and
binding obligation of such Trustee, enforceable against such Trustee in
accordance with its terms; that each Trustee is in compliance, generally and
with respect to acting as a Trustee under each Indenture to which it is a party,
with all applicable laws and regulations; and that
<PAGE>
 
Intermedia Communications Inc.

Page 4

each Trustee has the requisite organizational and legal power and authority to
perform its obligations under each Indenture to which it is a party.

     The opinions expressed herein are limited to the laws of the State of New
York, the corporate laws of the State of Delaware, and the federal laws of the
United States, and we express no opinion as to the effect on the matters covered
by this letter of the laws of any other jurisdiction.

     The opinions expressed herein are rendered solely for your benefit in
connection with the transactions described herein.  Such opinions may not be
used or relied upon by any other person, nor may this letter or any copies
thereof be furnished to a third party, filed with a governmental agency, quoted,
cited or otherwise referred to without our prior written consent, except that we
hereby consent to the filing of this opinion as an exhibit to the Registration
Statement and to the reference to our Firm under the caption "Legal Matters" in
the Prospectus contained therein.

                                        Very truly yours,
