              5 1/4% Convertible Trust Issued Preferred Securities
                 (Liquidation Amount $25 per Preferred Security)
                  guaranteed to the extent set forth herein by,
                      and convertible into common stock of

                           CENTRAL PARKING CORPORATION

                                  69,473 SHARES

                           CENTRAL PARKING CORPORATION
                          Common Stock, $0.01 par value

         This Prospectus relates to the 5 1/4% Convertible Trust Issued
Preferred Securities (the "Preferred Securities") liquidation preference $25 per
Preferred Security, which represent preferred undivided beneficial interests in
the assets of Central Parking Finance Trust, a statutory business trust formed
under the laws of the State of Delaware ("Central Parking Finance" or the
"Trust"), the shares of common stock, $0.01 par value per share (the "Company
Common Stock"), of Central Parking Corporation, a Tennessee corporation (the
"Company"), issuable upon conversion of the Preferred Securities and 69,473
shares of Company Common Stock being offered by certain selling shareholders.
The Company owns all the common securities issued by the Trust (the "Common
Securities" and, together with the Preferred Securities, the "Trust Securities")
representing undivided beneficial interests in the assets of the Trust. The
69,473 shares of Company Common Stock were issued in two separate acquisitions
by the Company pursuant to an exemption from the requirements of the Securities
Act of 1933, as amended (the "Securities Act"). The Preferred Securities were
issued and sold (the "Original Offering") on March 18, 1998 (the "Original
Offering Date") in transactions exempt from the registration requirements of the
Securities Act, in the United States to persons reasonably believed by the
Initial Purchasers (as defined below) of the Preferred Securities to be
qualified institutional buyers in reliance on Rule 144A under the Securities
Act) and outside the United States to non-U.S. persons in offshore transactions
in reliance on Regulation S under the Securities Act. The Trust exists for the
sole purpose of issuing the Trust Securities and investing the proceeds thereof
in an equivalent amount of 5 1/4% Convertible Subordinated Debentures due 2028
(the "Convertible Debentures") of the Company. Upon an event of default under
the Trust Agreement (as defined herein), the holders of the Preferred Securities
will have a preference over the holders of the Common Securities with respect to
payments in respect of distributions and payments upon redemption, liquidation
and otherwise.

         The Preferred Securities, the Company Common Stock issuable upon
conversion of the Preferred Securities and the additional 69,473 shares of
Common Stock (the "Offered Securities") may be offered and sold from time to
time by the holders named herein or by their transferees, pledgees, donees or
their successors (collectively, the "Selling Holders") pursuant to this
Prospectus. The Offered Securities may be sold by the Selling Holders from time
to time directly to purchasers or through agents, underwriters or dealers. See
"Plan of Distribution." If required, the names of any such agents or
underwriters involved in the sale of the Offered Securities and the applicable
agent's commission, dealer's purchase price or underwriter's discount, if any,
will be set forth in an accompanying supplement to this Prospectus (the
"Prospectus Supplement"). The Selling Holders will receive all of the net
proceeds from the sale of the Offered Securities and will pay all underwriting
discounts and selling commissions, if any, applicable to any such sale. The
Company is responsible for payment of all other expenses incident to the offer
and sale of the Offered Securities. The Selling Holders and any broker-dealers,
agents or underwriters which participate in the distribution of the Offered
Securities may be deemed to be "underwriters" within the meaning of the
Securities Act, and any commission received by them and any profit on the resale
of the Offered Securities purchased by them may be deemed to be underwriting
commissions or discounts under the Securities Act. See "Plan of Distribution"
for a description of indemnification arrangements.

         Holders of the Preferred Securities are entitled to receive cumulative
cash distributions at an annual rate of 5 1/4% of the liquidation amount of $25
per Preferred Security, accruing from the date of original issuance and payable
quarterly in arrears on each January 1, April 1, July 1 and October 1,
commencing July 1, 1998. See "Description of the Preferred
Securities--Distributions." The distribution rate and the distribution payment
dates and other payment dates for the Preferred Securities correspond to the
interest rate and interest payment dates and other payment dates for the
Convertible Debentures, which are the sole assets of the Trust. As a result, if
principal or interest is not paid on the Convertible Debentures, no amounts will
be paid with respect to the Preferred Securities.

         Each Preferred Security is convertible at the option of the holder
thereof, into shares of the Company Common Stock at a conversion rate of 0.4545
shares of Company Common Stock for each Preferred Security (equivalent to a
conversion price of $55.00 per share of Company Common Stock), subject to
adjustment in certain circumstances. The Company Common Stock is quoted on the
New York Stock Exchange ("NYSE") under the symbol "PK." On May 8, 1998, the last
reported sale price of the Company Common Stock on the NYSE was $45.5625.

CONSIDERED IN CONNECTION WITH AN INVESTMENT IN THE PREFERRED SECURITIES.

THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE SECURITIES
AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION PASSED UPON THE
ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS A
CRIMINAL OFFENSE.

                THE DATE OF THIS PROSPECTUS IS ____________, 1998

                                                 (Continued from previous page.)

         The Company has the right to defer payments of interest on the
Convertible Debentures at any time for up to 20 consecutive quarters (each, an
"Extension Period"), but not beyond the maturity of the Convertible Debentures.
If interest payments are so deferred, distributions on the Preferred Securities
also will be deferred. During any Extension Period, distributions will continue
to accrue with interest thereon (to the extent permitted by applicable law) at a
rate of 5 1/4% per annum compounded quarterly. During any Extension Period,
holders of Preferred Securities will be required to include such deferred
interest in their gross income for United States federal income tax purposes in
advance of receipt of the cash distributions with respect to such deferred
interest payments. Moreover, if a holder of Preferred Securities converts its
Preferred Securities into Company Common Stock during any Extension Period, the
holder will not receive any cash related to the deferred distributions. There
could be multiple Extension Periods of varying lengths throughout the term of
Convertible Debentures (but distributions would continue to accumulate quarterly
and accrue interest until the end of any such Extension Period). See "Risk
Factors--Option to Extend Interest Payment Periods," "Description of the
Preferred Securities--Distributions" and "Description of the Convertible
Debentures--Option to Extend Interest Payment Periods."

         The payment of distributions out of moneys held by the Trust and
payments on liquidation of the Trust or the redemption of Preferred Securities,
as described below, are guaranteed by the Company (the "Guarantee") to the
extent the Trust has funds available therefor as described under "Description of
the Guarantee." The Guarantee, when taken together with the Company's
obligations under the Indenture (as defined herein) pursuant to which the
Convertible Debentures are issued and its obligations under the Trust Agreement,
including its obligations to pay costs, expenses, debts and liabilities of the
Trust (other than with respect to the Trust Securities), provide a full and
unconditional guarantee of amounts due on the Preferred Securities. The
Company's obligations under the Guarantee rank (i) subordinate and junior to all
other liabilities of the Company except any liabilities that may be pari passu
by their terms, (ii) pari passu with the most senior preferred stock issued from
time to time by the Company and with any guarantee now or hereafter entered into
by the Company in respect of any preferred or preference stock or any preferred
securities of any affiliate of the Company and (iii) senior to the Company
Common Stock. See "Description of the Guarantee." The obligations of the Company
under the Convertible Debentures are subordinate and junior in right of payment
to Senior Indebtedness (as defined herein) of the Company. See "Capitalization."

         The Convertible Debentures are redeemable by the Company, in whole or
in part, from time to time, on or after April 3, 2001 at the redemption prices
set forth herein. The Convertible Debentures may also be redeemed at any time
upon the occurrence of a Tax Event (as defined herein). If the Company redeems
Convertible Debentures, the Trust must redeem Trust Securities on a pro rata
basis having an aggregate liquidation amount equal to the aggregate principal
amount of the Convertible Debentures so redeemed at a redemption price
corresponding to the redemption price of the Convertible Debentures plus accrued
and unpaid distributions thereon (the "Redemption Price") to the date fixed for
redemption. See "Description of the Preferred Securities--Redemption." The
Preferred Securities will be redeemed upon maturity of the Convertible
Debentures. In addition, the Trust will be dissolved upon the occurrence of a
Tax Event arising from a change in law or a change in legal interpretation
regarding tax matters, unless the Convertible Debentures are redeemed in the
limited circumstances described herein. The Trust will also be dissolved upon
the occurrence of an Investment Company Event (as defined herein). Upon
dissolution of the Trust, the Convertible Debentures will be distributed to the
holders of the Preferred Securities, on a pro rata basis, in lieu of any cash
distribution. If the Convertible Debentures are distributed to the holders of
the Preferred Securities, the Company will use its best efforts to cause the
Convertible Debentures to be listed on the NYSE or other national securities
exchange or similar organization as the Preferred Securities are then listed or
quoted. See "Description of the Preferred Securities--Special Event Redemption
or Distribution" and "Description of the Convertible Debentures."

         In the event of the liquidation, winding up or termination of the
Trust, the holders of the Preferred Securities will be entitled to receive for
each Preferred Security a liquidation amount of $25 plus accrued and unpaid
distributions thereon (including interest thereon) to the date of payment,
unless, in connection with such dissolution, Convertible Debentures are
distributed to the holders of the Preferred Securities. See "Description of the
Preferred Securities-- Liquidation Distribution Upon Dissolution."

         The Preferred Securities sold to qualified institutional buyers in
reliance on Rule 144A and outside the United States in reliance on Regulation S
under the Securities Act of 1933, as amended (the "Securities Act") are
represented by a global certificate or certificates registered in the name of
The Depository Trust Company ("DTC") or its nominee. Beneficial interests in
such Preferred Securities are shown on, and transfers thereof will be effected
only through, records maintained by the participants in DTC. Beneficial
interests in the Regulation S Global Security (as defined herein) initially may
be held only through the Euroclear System ("Euroclear") and Cedel Bank, societe
anonyme ("Cedel Bank"). After initial issuance of the Global Securities (as
defined herein), Preferred Securities in certificated form (the "Certificated
Securities") may be issued in exchange for the Global Securities on the terms
and under the limited circumstances set forth in the indenture governing the
Convertible Debentures (the "Indenture"). See "Description of the Preferred
Securities--Book-Entry Only Issuance-The Depository Trust Company."

         SPECIAL CAUTIONARY NOTICE REGARDING FORWARD-LOOKING STATEMENTS

         This Prospectus contains or incorporates by reference certain
forward-looking statements within the meaning of Section 27A of the Securities
Act and Section 21E of the Securities Exchange Act of 1934, as amended (the
"Exchange Act"), which are intended to be covered by the safe harbors created
thereby. Those statements include, but may not be limited to, the discussions of
the Company's expectations concerning its future profitability, the discussion
of the Company's strategic relationships, the Company's operating and growth
strategy, including possible strategic acquisitions, and the Company's
assumptions regarding certain matters, including anticipated cost savings, in
preparation of the unaudited pro forma financial information. Investors are
cautioned that all forward-looking statements involve risks and uncertainties
including, without limitation, the factors set forth under the caption "Risk
Factors" in this Prospectus. Although the Company believes that the assumptions
underlying the forward-looking statements contained herein are reasonable, any
of the assumptions could be inaccurate and, therefore, there can be no assurance
that the forward-looking statements included or incorporated by reference in
this Prospectus will prove to be accurate. In light of the significant
uncertainties inherent in the forward-looking statements included or
incorporated by reference herein, the inclusion of such information should not
be regarded as a representation by the Company or any other person that the
objectives and plans of the Company will be achieved.


                              AVAILABLE INFORMATION

         The Company is subject to the informational requirements of the
Exchange Act and in accordance therewith files reports, proxy statements and
other information with the Securities and Exchange Commission (the
"Commission"). The reports, proxy statements and other information filed by the
Company may be inspected and copied at the public reference facilities
maintained by the Commission at Room 1024, 450 Fifth Street, N.W., Washington,
D.C. 20549, and at the Commission's regional offices located at 7 World Trade
Center, New York, New York 10048, and Northwestern Atrium Center, 500 West
Madison Street Suite 1400, Chicago, Illinois 60661. Copies of such material can
be obtained at prescribed rates from the Public Reference Section of the
Commission at 450 Fifth Street, N.W., Washington, D.C. 20549. The Company Common
Stock is listed on the NYSE, and reports and other information concerning the
Company can also be inspected at the office of the NYSE, 20 Broad Street, New
York, New York 10005. Such material may also be accessed electronically by means
of the Commission's home page on the internet at http://www.sec.gov.

         The Trust and the Company have filed with the Securities and Exchange
Commission (the "Commission") a Registration Statement on Form S-3 under the
Securities Act, with respect to the securities offered hereby. This Prospectus
constitutes a part of the Registration Statement and does not contain all of the
information set forth in the Registration Statement and the exhibits and
schedules thereto, certain portions of which have been omitted in accordance
with the rules and regulations of the Commission. Statements contained in the
Prospectus as to any contracts, agreements, or other documents filed as an
exhibit to, or incorporated by reference in, the Registration Statement are
qualified in all respects to the copy of such contract, agreement, or other
document filed as an exhibit or incorporated by reference in the Registration
Statement. For further information with respect to the Trust, the Company and
the securities offered hereby, reference is hereby made to the Registration
Statement, including the exhibits and schedules thereto.

         No separate financial statements of the Trust have been included or
incorporated by reference herein. The Trust and the Company do not believe that
such financial statements would be material to the holders of the Preferred
Securities because (i) all of the voting securities of the Trust will be owned,
directly or indirectly, by the Company, a reporting company under the Exchange
Act, (ii) the Trust has no independent operations but exists for the sole
purpose of issuing securities representing undivided beneficial interests in its
respective assets and investing the proceeds thereof in the Convertible
Debentures issued by the Company and (iii) the obligations of the Trust under
the Preferred Securities are fully and unconditionally guaranteed by the Company
to the extent that the Trust has funds available to meet such obligations. See
"Central Parking Finance Trust," "Description of the Preferred Securities,"
"Description of the Guarantee" and "Description of the Convertible Debentures."

         In future filings under the Exchange Act, a footnote to the Company's
annual consolidated financial statements will state that the Trust is
consolidated with the Company and that the sole assets of the Trust are the
Convertible Debentures. The Guarantee, when taken together with the Convertible
Debentures and the Company's obligations to pay all fees and expenses of the
Trust, constitutes a guarantee to the extent described herein by the Company of
the distribution, liquidation and other payments payable to the holders of the
Preferred Securities. The Guarantee does not apply, however, to distributions by
the Trust unless and until the Trust has funds available therefor, as more fully
described under "Description of the Guarantee."

                                  RISK FACTORS

         The following factors should be considered, together with the other
information contained or incorporated by reference in this Prospectus, in
evaluating the Company and the Trust before purchasing the Offered Securities.

INTEGRATION OF ACQUISITIONS

         The Company completed three acquisitions in fiscal 1997 and the
Diplomat and Kinney Acquisitions (defined herein) in the first two quarters of
fiscal 1998. These acquisitions have substantially increased the number of
persons employed by the Company, the number of facilities operated by the
Company, and the geographic markets serviced by the Company. Although the
Company believes that it can successfully integrate and manage acquired
operations and achieve certain economies of scale, there can be no assurance
that acquisitions will be integrated successfully into the Company's operations,
that cost savings or operating synergies will be realized, to the extent
anticipated by the Company or that the acquired operations will achieve levels
of profitability that justify the Company's investments therein. Furthermore,
there can be no assurance that the Company will be able to consummate parking
facility or company acquisitions in the future at the rate currently expected,
if at all, or, if completed, that any acquired facility or company will be
successfully integrated into the Company's operations. Moreover, because of the
price paid by the Company or because of the performance of acquired operations
after such acquisitions, there can be no assurance that the results of the
acquired operations will not be dilutive to the Company's per share earnings.
Any acquisition contemplated or completed by the Company may result in adverse
short-term effects on the Company's reported operating results, divert
management's attention, introduce difficulties in retaining, hiring and training
key personnel, and introduce risks associated with unanticipated problems or
legal liabilities, some or all of which could have a material adverse effect on
the Company's financial condition and results of operations. The Company
receives information regarding potential acquisitions from time to time;
however, there are currently no material acquisitions which the Company believes
are more likely than not to occur.

ABILITY TO MANAGE GROWTH

         The Company intends to continue to expand its business by adding
management contracts and leases and by acquiring additional parking facilities
and operators. The Company's growth will be affected by the results of
operations of added parking facilities which will depend upon contract terms,
government licenses and approvals, and local competitive environments. The
nature of licenses and approvals, and the timing and likelihood of obtaining
them, vary widely from state to state and country to country. The Company's
growth will also be directly affected by the Company's ability to obtain
suitable financing and by the competitive environment for acquisitions. Some of
the acquired operations may be located in geographic markets in which the
Company has little or no presence. Successful integration and management of
additional facilities will depend on a number of factors, many of which are
beyond the Company's control. The Company's growth plans will also place
significant demands on the Company's management and operating personnel and will
require the Company to improve its operational, financial, and management
information systems.

DEPENDENCE ON MANAGEMENT CONTRACTS AND LEASES

         The principal sources of the Company's revenues are management
contracts and leases relating to parking facilities owned by unaffiliated
property owners. For fiscal 1995, 1996 and 1997 revenues from management
contracts accounted for 25.2%, 23.8%, and 18.9%, respectively, and revenues from
leased facilities accounted for 70.6%, 71.8%, and 74.7%, respectively, of the
Company's total revenues. For the three month periods ended December 31, 1996
and 1997, revenues from management contracts accounted for 22.5% and 17.1%,
respectively, and revenues from leased facilities accounted for 73.2% and 77.5%,
respectively, of the Company's total revenues. Management contracts, in general,
are for terms of one to three years, but are cancelable by the property owner on
short notice. Leases generally are for three to ten year terms. There can be no
assurance that the Company will be able to maintain or renew its management
contracts and leases on favorable terms. The loss, or renewal on less favorable
terms, of a substantial number of management contracts or leases could have a
material adverse effect on the Company's financial condition and results of
operations. Under its management contracts, the Company provides ancillary
services such as insurance, accounting, equipment leasing, and consulting. A
material reduction in the profit margins associated with these ancillary
services provided under its management contracts, caused by, among other things,
increases in costs or claims associated with, or reductions in the number of
clients purchasing, insurance provided by the Company could have a material
adverse effect on the Company's financial condition and results of operations.

DEPENDENCE ON PROPERTY PERFORMANCE

         The Company's revenues and profitability are dependent on the
performance of the parking facilities it owns, leases and manages. The Company's
revenues from leased and owned parking facilities consist of parking fees
collected by such facilities. For fiscal 1995, 1996, and 1997 revenues from
leased and owned facilities accounted for 74.8%, 76.2%, and 81.1%, respectively,
of the Company's total revenues. For the three month periods ended December 31,
1996 and 1997, revenues from leased and owned facilities accounted for 77.5% and
82.9%, respectively, of the Company's total revenues. The Company's leases
generally require the Company to make a fixed monthly lease payment regardless



                                        6

<PAGE>   7



of the parking fees collected. Some management contracts provide for payment to
the Company based on a percentage of gross revenues generated by the parking
facility. Accordingly, performance of the Company's parking facilities depends,
in part, on the Company's ability to negotiate favorable contract terms, the
Company's ability to control operating expenses, financial conditions prevailing
generally and in areas where parking facilities are located, the nature and
extent of competitive parking facilities in the area, and the real estate market
generally.

RANKING OF SUBORDINATE OBLIGATIONS UNDER THE GUARANTEE AND CONVERTIBLE
DEBENTURES

         The Company's obligations under the Guarantee are subordinate and
junior in right of payment to all liabilities of the Company and pari passu with
the most senior preferred stock issued from time to time, if any, by the
Company. The obligations of the Company under the Convertible Debentures are
subordinate and junior in right of payment to all present and future Senior
Indebtedness of the Company and pari passu with obligations to or rights of the
Company's other general unsecured creditors. No payment of principal (including
redemption payments, if any), premium, if any, or interest on the Convertible
Debentures may be made if (i) any Senior Indebtedness of the Company is not paid
when due and any applicable grace period with respect to such default has ended
with such default not having been cured or waived or ceasing to exist, or (ii)
the maturity of any Senior Indebtedness has been accelerated because of a
default. As of December 31, 1997, Senior Indebtedness aggregated approximately
$101.9 million. In addition, because certain of the Company's operations are
conducted through its subsidiaries and the subsidiaries have not guaranteed the
payment of principal of and interest on the Convertible Debentures, all
liabilities of the subsidiaries, including trade payables, are effectively
senior to the Convertible Debentures and the Guarantee. There are no terms in
the Preferred Securities, the Convertible Debentures or the Guarantee that limit
the Company's or any subsidiary's ability to incur additional indebtedness,
including indebtedness that ranks senior to the Convertible Debentures and the
Guarantee. See "Description of the Guarantee--Status of the Guarantee;
Subordination" and "Description of the Convertible Debentures."

SUBORDINATION AND RESTRICTIVE COVENANTS

         The ability of the Trust to pay amounts due on the Preferred Securities
is wholly dependent upon the Company making payments on the Convertible
Debentures. Since certain of the Company's operations are conducted through its
subsidiaries, the ability of the Company to pay interest and principal on the
Convertible Debentures, and, therefore, for the Trust to make distributions and
other payments on the Preferred Securities, may be dependent on the
subsidiaries' ability to pay dividends to the Company. Because the subsidiaries
do not guarantee the payment of principal of and interest on the Convertible
Debentures, claims of holders of the Preferred Securities will effectively be
subordinate to the claims of creditors of the subsidiaries, including trade
creditors. See "--Ranking of Subordinate Obligations Under the Guarantee and
Convertible Debentures."

         The ability of the Company's subsidiaries to pay dividends, as well as
repay debt, is restricted by the provisions of the New Credit Facility and is
dependent on the Company's financial and operating performance, which, in turn,
is subject to prevailing economic conditions and to financial, business and
other factors beyond its control. There can be no assurance that financial
results that comply with the restrictive covenants and financial tests in the
New Credit Facility will be achieved.

RIGHTS UNDER THE GUARANTEE

         It is expected that at the time the Shelf Registration Statement
becomes effective, the Guarantee will be qualified as an indenture under the
Trust Indenture Act of 1939, as amended (the "Trust Indenture Act"). The
Guarantee Trustee (as defined herein) will act as indenture trustee under the
Guarantee for the purposes of compliance with the provisions of the Trust
Indenture Act. The Guarantee Trustee will hold the Guarantee for the benefit of
the holders of the Preferred Securities.

         The Guarantee guarantees to the holders of the Preferred Securities the
payment of (i) any accrued and unpaid distributions that are required to be paid
on the Preferred Securities, to the extent the Trust has funds available
therefor, (ii) the Redemption Price, including all accrued and unpaid
distributions with respect to Preferred Securities called for redemption by the
Trust, to the extent the Trust has funds available therefor, and (iii) upon a
voluntary or involuntary dissolution, winding-up or termination of the Trust
(other than in connection with the distribution of Convertible Debentures to the
holders of Preferred Securities or a redemption of all the Preferred
Securities), the lesser of (a) the aggregate of the liquidation amount and all
accrued and unpaid distributions on the Preferred Securities to the date of the
payment, to the extent the Trust has funds available therefor, or (b) the amount
of assets of the Trust remaining available for distribution to holders of the
Preferred Securities in liquidation of the Trust. The holders of a majority in
liquidation amount of the Preferred Securities have the right to direct the
time, method and place of conducting any proceeding for any remedy available to
the Guarantee Trustee or to direct the exercise of any trust or power conferred
upon the Guarantee Trustee under the Guarantee. Notwithstanding the foregoing,
if the Company has failed to make a payment under the Guarantee, any holder of
Preferred Securities may directly institute a legal proceeding against the
Company to enforce its rights under the Guarantee without first instituting a
legal proceeding against the Trust, the Guarantee Trustee or any other person or
entity. If the Company were to default on its obligation to pay amounts payable



                                        7

<PAGE>   8



on the Convertible Debentures, the Trust would lack available funds for the
payment of distributions or amounts payable on redemption of the Preferred
Securities or otherwise, and, in such event, holders of the Preferred Securities
would not be able to rely upon the Guarantee for payment of such amounts.
Instead, holders of the Preferred Securities would rely on the enforcement by
(i) the Property Trustee of its rights as registered holder of the Convertible
Debentures against the Company pursuant to the terms of the Convertible
Debentures or (ii) such holder of its right against the Company under certain
circumstances to enforce payments on the Convertible Debentures. See
"--Enforcement of Certain Rights by Holders of Preferred Securities,"
"Description of the Guarantee" and "Description of the Convertible Debentures."
The Trust Agreement provides that each holder of Preferred Securities, by
acceptance thereof, agrees to the provisions of the Guarantee, including the
subordination provisions thereof, and the Indenture.

OPTION TO EXTEND INTEREST PAYMENT PERIODS

         The Company has the right under the Indenture to defer payments of
interest on the Convertible Debentures by extending the interest payment period
at any time, and from time to time, on the Convertible Debentures. As a
consequence of such an extension, quarterly distributions on the Preferred
Securities would be deferred (but despite such deferral would continue to accrue
interest thereon, compounded quarterly) by the Trust during any such extended
interest payment period. Such right to extend the interest payment period for
the Convertible Debentures is limited to a period not exceeding 20 consecutive
quarters, during which no interest shall be due and payable; provided, that no
such Extension Period may extend beyond the maturity date of the Convertible
Debentures. In the event that the Company exercises this right to defer interest
payments, the Company has agreed, among other things, (a) not to declare or pay
dividends on, or make a distribution with respect to, or redeem or purchase or
acquire, or make a liquidation payment with respect to, any of its capital stock
(other than (i) purchases or acquisitions of shares of Company Common Stock in
connection with the satisfaction by the Company of its obligations under any
employee benefit plans or the satisfaction by the Company of its obligations
pursuant to any contract or security requiring the Company to purchase shares of
Company Common Stock, (ii) as a result of a reclassification of the Company's
capital stock or the exchange or conversion of one class or series of the
Company's capital stock for another class or series of the Company's capital
stock or (iii) the purchase of fractional interests in shares of the Company's
capital stock pursuant to the conversion or exchange provisions of such capital
stock or the security being converted or exchanged (or make any guarantee
payments with respect to the foregoing)), (b) not to make any payment of
interest, principal or premium, if any, on or repay, repurchase or redeem any
debt securities (including guarantees) issued by the Company that rank pari
passu with or junior to the Convertible Debentures and (c) not to make any
guarantee payments with respect to the foregoing (other than pursuant to the
Guarantee). Prior to the termination of any such extension period, the Company
may further extend the interest period; provided, that such Extension Period,
together with all such previous and further extensions thereof, may not exceed
20 consecutive quarters or extend beyond the maturity date of the Convertible
Debentures. Upon the termination of any Extension Period and the payment of all
amounts then due, the Company may commence a new Extension Period, subject to
the above requirements. See "Description of the Preferred
Securities--Distributions" and "Description of the Convertible
Debentures--Option to Extend Interest Payment Periods."

         Should the Company exercise its right to defer payments of interest by
extending the interest payment period, each holder of Preferred Securities will
continue to accrue income (as original issue discount ("OID")) in respect of the
deferred interest allocable to its Preferred Securities for federal income tax
purposes, which will be allocated but not distributed, to holders of record of
Preferred Securities. As a result, each such holder of Preferred Securities will
recognize income for federal income tax purposes in advance of the receipt of
cash and will not receive the cash from the Trust related to such income if such
holder disposes of its Preferred Securities prior to the record date for the
date on which distributions of such amounts are made. The Company has no current
intention of exercising its right to defer payments of interest by extending the
interest payment period on the Convertible Debentures. However, should the
Company determine to exercise such right in the future, the market price of the
Preferred Securities is likely to be affected. A holder that disposes of its
Preferred Securities during an Extension Period, therefore, might not receive
the same return on its investment as a holder that continues to hold its
Preferred Securities. In addition, as a result of the existence of the Company's
right to defer interest payments, the market price of the Preferred Securities
(which represent an undivided beneficial interest in the Convertible Debentures)
may be more volatile than other securities on which OID accrues that do not have
such rights. See "United States Federal Income Taxation--Interest Income and
Original Issue Discount."

COMPETITION

         The parking industry is highly competitive. The Company's competitors
range from small single-lot operators to large regional and national
multi-facility operators, and include municipal and other governmental entities.
Some of the Company's present and potential competitors have or may obtain
greater financial and marketing resources than those of the Company.
Furthermore, the Company competes for qualified management personnel with other
parking facility operators, with property management companies, and with
property owners. There can be no assurance that the Company will not encounter
increased competition in the future, due to, among other things, increased
construction of parking facilities, which could limit its ability to attract
customers, expand its business, or maintain profitable pricing levels, and which
could have a material adverse effect on the Company's financial condition or
results of operations or decrease its market share. The Company competes for
acquisitions with other parking facility operators, real estate



                                        8

<PAGE>   9



developers and real estate investment trusts. There can be no assurance that the
Company will not encounter increased competition for acquisitions in the future
and that such competition will not have an adverse effect on the Company's
ability to complete acquisitions or on prices paid for acquisitions.

FOREIGN CURRENCY EXCHANGE RATES

         The Company operates in the United Kingdom, Germany, Mexico, Malaysia,
Canada, and Spain, maintains a business development office in the Netherlands,
and intends to expand its business in these and other international locations.
For the quarter ended December 31, 1997, revenues from United Kingdom operations
represented 95.9% of the revenues generated by foreign operations, excluding
earnings from joint ventures. The Company receives revenues and incurs expenses
in various foreign currencies in connection with its foreign operations and, as
a result, the Company is subject to currency exchange rate fluctuations. The
Company intends to continue to invest in foreign leased or owned parking
facilities, either independently or through joint ventures, where appropriate,
and may become increasingly exposed to foreign currency fluctuations. Presently,
the Company has limited exposure to foreign currency risk and anticipates
implementing a hedge program if such risk materially increases.

DEPENDENCE ON KEY MANAGEMENT

         The success of the Company is highly dependent on the continued
services of the Company's management team. The loss of services of one or more
members of the Company's senior management team could have a material adverse
effect on the Company's financial condition and results of operations. Although
the Company has entered into employment agreements with, and historically has
been successful in retaining the services of, its senior management, there can
be no assurance that the Company will be able to retain such personnel in the
future. The Company is a beneficiary of certain life insurance policies on
certain key executives ranging from $100,000 to approximately $1.2 million.

ENVIRONMENTAL AND OTHER REGULATIONS

         Under various federal, state, and local environmental laws, ordinances,
and regulations, a current or previous owner or operator of real property may be
liable for the cost of removal or remediation of hazardous or toxic substances
on, under, or in such property. Such laws typically impose liability without
regard to whether the owner or operator knew of, or was responsible for, the
presence of such hazardous or toxic substances. In connection with the ownership
or operation of parking facilities, the Company may be potentially liable for
such costs. Although the Company is currently not aware of any material
environmental claims pending or threatened against it or any of its owned or
operated parking facilities, there can be no assurance that a material
environmental claim will not be asserted against the Company or against its
owned or operated parking facilities. The cost of defending against claims of
liability, or of remediating a contaminated property, could have a material
adverse effect on the Company's financial condition or results of operations.

         Various other governmental regulations affect the Company's operation
of parking facilities, both directly and indirectly, including air quality laws,
licensing laws, and the Americans with Disabilities Act of 1990 (the "ADA").
Under the ADA, all public accommodations, including parking facilities, are
required to meet certain federal requirements related to access and use by
disabled persons. Although management believes that the parking facilities it
owns and operates are in substantial compliance with these requirements, a
determination that the Company or the facility owner is not in compliance with
the ADA could result in the imposition of fines or damage awards against the
Company.

ENFORCEMENT OF CERTAIN RIGHTS BY HOLDERS OF PREFERRED SECURITIES

         If a Declaration Event of Default (as defined herein) occurs and is
continuing, then the holders of Preferred Securities would rely on the
enforcement by the Property Trustee of its rights as a holder of the Convertible
Debentures against the Company. In addition, the holders of a majority in
liquidation amount of the Preferred Securities have the right to direct the
time, method and place of conducting any proceeding for any remedy available to
the Property Trustee or to direct the exercise of any trust or power conferred
upon the Property Trustee under the Trust Agreement, including the right to
direct the Property Trustee to exercise the remedies available to it as a holder
of the Convertible Debentures. If the Property Trustee fails to enforce its
rights under the Convertible Debentures, any holder of Preferred Securities may
directly institute a legal proceeding against the Company to enforce the
Property Trustee's rights under the Convertible Debentures without first
instituting any legal proceeding against the Property Trustee or any other
person or entity. Notwithstanding the foregoing, if a Declaration Event of
Default has occurred and is continuing and such event is attributable to the
failure of the Company to pay interest or principal on the Convertible
Debentures on the date such interest or principal is otherwise payable (or in
the case of redemption, on the redemption date), then a holder of Preferred
Securities may directly institute a proceeding for enforcement of payment to
such holder of the principal of or interest on the Convertible Debentures having
a principal amount equal to the aggregate liquidation amount of the Preferred
Securities of such holder (a "Direct Action") on or after the respective due
date specified in the Convertible Debentures. In connection with such Direct
Action, the Company will be subrogated to the rights of such holder of




                                        9

<PAGE>   10
Preferred Securities under the Declaration to the extent of any payment made by
the Company to such holder of Preferred Securities in such Direct Action. The
holders of Preferred Securities will not be able to exercise directly any other
remedy available to the holders of the Convertible Debentures. The Indenture
provides that the Indenture Trustee (as defined herein) shall give holders of
the Convertible Debentures notice of all uncured defaults or events of default
within 30 days after occurrence. However, except in the case of a default or an
event of default in payment on the Convertible Debentures, the Indenture Trustee
(as defined herein) is protected in withholding such notice if its officers or
directors in good faith determine that withholding of such notice is in the
interest of the holders.

SPECIAL EVENT REDEMPTION OR DISTRIBUTION

         Upon the occurrence of a Special Event (as defined herein), the Trust
shall be dissolved, except in the limited circumstance described below, with the
result that the Convertible Debentures would be distributed to the holders of
the Trust Securities in connection with the liquidation of the Trust. In the
case of a Special Event that is a Tax Event, in certain circumstances, the
Company shall have the right to redeem the Convertible Debentures, in whole or
in part, in lieu of a distribution of the Convertible Debentures by the Trust,
in which event the Trust will redeem the Trust Securities on a pro rata basis to
the same extent as the Convertible Debentures are redeemed by the Company. See
"Description of the Preferred Securities--Special Event Redemption or
Distribution."

         Under current federal income tax law, a distribution of Convertible
Debentures upon the dissolution of the Trust would not be a taxable event to
holders of the Preferred Securities. Upon occurrence of a Special Event,
however, a dissolution of the Trust in which holders of the Preferred Securities
receive cash would be a taxable event to such holders. See "United States
Federal Income Taxation--Receipt of Convertible Debentures or Cash Upon
Liquidation of the Trust."

         There can be no assurance as to the market prices for the Preferred
Securities or the Convertible Debentures that may be distributed in exchange for
Preferred Securities if a dissolution or liquidation of the Trust were to occur.
Accordingly, the Preferred Securities that an investor may purchase, or the
Convertible Debentures that a holder of Preferred Securities may receive on
dissolution and liquidation of the Trust, may trade at a discount to the price
that the investor paid to purchase the Preferred Securities offered hereby.
Because holders of Preferred Securities may receive Convertible Debentures upon
the occurrence of a Special Event, prospective purchasers of Preferred
Securities are also making an investment decision with regard to the Convertible
Debentures and should carefully review all the information regarding the
Convertible Debentures contained in this Prospectus. See "Description of the
Preferred Securities--Special Event Redemption or Distribution."

LIMITED VOTING RIGHTS

         Holders of Preferred Securities have limited voting rights and are not
entitled to vote to appoint, remove or replace, or to increase or decrease the
number of, Issuer Trustees, which voting rights are vested exclusively in the
holder of the Common Securities. See "Description of the Preferred
Securities--Voting Rights."

VARIATIONS IN QUARTERLY OPERATING RESULTS

         The Company has experienced fluctuations in its quarterly revenues and
profitability. These fluctuations are caused by a variety of factors including
the timing of gains on sales of owned facilities, preopening costs, the effect
of weather on travel and transportation patterns, and local and national
economic conditions. There can be no assurance that fluctuations in revenues and
net earnings will not cause the market price of the Company Common Stock to
fluctuate substantially. Results for any particular quarter may not be
indicative of future results or results for the full fiscal year.

CONTROL BY MR. CARELL AND FAMILY

         Monroe J. Carell, Jr., Chairman and Chief Executive Officer of the
Company, trusts established for the benefit of his family, and foundations
controlled by Mr. Carell and his family, beneficially own an aggregate of
approximately 61.8% of the outstanding shares of Company Common Stock as of
December 31, 1997, after giving pro forma effect to the Company's Common Stock
offering in March 1998. Accordingly, such persons have majority control of the
Company and the ability to elect all members of the Board of Directors; to
effect or prevent a merger or a sale of assets; to adopt, amend, or repeal the
Company's Amended and Restated Charter and Bylaws; and to take certain other
actions requiring the vote or consent of the Company's shareholders.

VOLATILITY OF MARKET PRICE FOR COMPANY COMMON STOCK

         From time to time, there may be significant volatility in the market
price of the Company Common Stock. The Company believes that the current market
price of the Company Common Stock reflects expectations that the Company will be
able to continue to operate its facilities profitably, add management contracts
and leases and acquire new facilities at a significant rate, and operate them
profitably. If the Company is unable to operate its facilities profitably or add
new facilities at a pace that reflects the expectations of the market, investors
could sell shares of the Company


                                       10

<PAGE>   11



Common Stock at or after the time that it becomes apparent that the expectations
may not be realized, resulting in a decrease in the market price of the Company
Common Stock. In addition to quarterly operating results of the Company, changes
in earnings estimates by analysts, general conditions in the economy, the
financial markets, or the parking industry, or other developments affecting the
Company could cause the market price of the Company Common Stock to fluctuate
substantially. The stock market may experience extreme price and volume
fluctuations and such volatility may have a significant effect on the market
price of the Company Common Stock for reasons unrelated to the Company's
operating performance. See "Price Range of Company Common Stock and Dividend
Policy."

TRADING CHARACTERISTICS OF PREFERRED SECURITIES

         The Preferred Securities may trade at a price that does not fully
reflect the value of accrued but unpaid interest with respect to the underlying
Convertible Debentures. In addition, as a result of the Company's right to defer
interest payments, the market price of the Preferred Securities (which represent
an undivided interest in the assets of the Trust) may be more volatile than
other similar securities where the issuer does not have such right to defer
interest payments. A holder who disposes of his Preferred Securities between
record dates for payments of distributions thereon will be required to include
accrued but unpaid interest on the Convertible Debentures through the date of
disposition in income as ordinary income (i.e., OID) and to add such amount to
his adjusted tax basis in his pro rata share of the underlying Convertible
Debentures deemed disposed of. To the extent the selling price is less than the
holder's adjusted tax basis (which will include, in the form of OID, all accrued
but unpaid interest), a holder will recognize a capital loss. Subject to certain
limited exceptions, capital losses cannot be applied to offset ordinary income
for federal income tax purposes. See "United States Federal Income
Taxation--Interest Income and Original Issue Discount" and "--Sales of Preferred
Securities."

LACK OF PUBLIC MARKET FOR THE PREFERRED SECURITIES

         There is no existing trading market for the Preferred Securities, and
there can be no assurance regarding the future development of a market for the
Preferred Securities, or the ability of holders of the Preferred Securities to
sell their Preferred Securities or the price at which such holders may be able
to sell their Preferred Securities. If such a market were to develop, the
Preferred Securities could trade at prices that may be higher or lower than the
initial offering price depending on many factors, including prevailing interest
rates, the price of the Company Common Stock, the Company's operating results,
any election by the Company to extend interest payment periods and the market
for similar securities. The Initial Purchasers currently make a market in the
Preferred Securities. The Initial Purchasers are not obligated to do so,
however, and any market making with respect to the Preferred Securities may be
discontinued at any time without notice. Therefore, there can be no assurance as
to the liquidity of any trading market for the Preferred Securities or that an
active public market for the Preferred Securities will develop. The Company does
not intend to apply for listing or quotation of the Preferred Securities on any

                                   THE COMPANY

         Central Parking Corporation (the "Company") is a leading provider of
parking services operating, as of December 31, 1997, 1,834 parking facilities
containing approximately 757,000 spaces in 34 states, the District of Columbia,
Puerto Rico, the United Kingdom, Germany, Canada, Mexico, Malaysia, and Spain.
The Company also has a business development office in the Netherlands. As of
April 1, 1998, the Company operated approximately 2,307 parking facilities
containing approximately 950,000 spaces. In each of the last five years, the
Company has increased the number of facilities it operates by approximately 150
facilities, excluding acquisitions and major property purchases. The Company's
leadership position in the parking industry is a result of applying professional
management strategies to a fragmented industry managed largely by small local
operators; developing relationships with key real estate managers and
developers, including sports arena operators; understanding the needs of the
parking public; applying technology to parking services; and retaining employees
through formal training programs and performance-based compensation.

         The Company provides parking management services at multi-level parking
facilities and surface lots. It also provides parking consulting, shuttle,
valet, parking meter enforcement, and billing and collection services. The
Company operates parking facilities under three general types of arrangements:
management contracts, leases, and fee ownership. As of December 31, 1997, the
Company operated 995 parking facilities under management contracts, 781 parking
facilities under leases, and owned, either independently or through joint
ventures, 58 parking facilities. Including the Kinney Acquisition, the Company
currently operates approximately 1,165 parking facilities under management
contracts, 1,006 parking facilities under leases and owns 66 parking facilities.

         The International Parking Institute (the "IPI") estimates that there
are 35,000 parking facilities in the United States generating approximately
$26.0 billion of annual revenues, which is divided evenly between commercial and
governmental operators. The commercial parking services business is very
fragmented, consisting of a few national companies and approximately 1,000
small, privately-held local and regional operators. The Company believes that it
has the opportunity to consolidate a portion of this fragmented, localized
industry by using its competitive advantages with regard to scale, financial
strength, technology, controls, and professionalism, all of which are becoming
increasingly important in the parking services business. For the same reasons,
the Company believes that it is well-positioned to be selected by municipal and
other governmental entities to operate their parking facilities and provide
parking-related services as such entities move toward outsourcing and
privatization.

         The Company distinguishes itself from its competitors by combining a
reputation for professional integrity and quality management with operating
strategies designed to increase the revenues of parking operations for its
clients. The Company's clients include some of the nation's largest owners and
developers of mixed-use projects, major office building complexes, sports
stadiums, and hotels, as well as several municipalities. Parking facilities
operated by the Company include, among others, certain terminals operated by BAA
Heathrow International Airport (London), the Prudential Center (Boston), One
Penn Plaza (New York), Ericsson Stadium (Charlotte), Busch Stadium (St. Louis),
Reunion Arena (Dallas), Coors Field (Denver), Cinergy Field (Cincinnati), Turner
Stadium (Atlanta), and various parking facilities owned by the Hyatt and Westin
hotel chains, the Rouse Company, Faison Associates, May Department Stores,
Equity Office Properties, and Crescent Real Estate.

         The Company's growth strategy is to increase revenues and profitability
by (i) increasing its market share through take-aways of competitors' contracts,
winning new management and lease contracts, purchasing properties, and nurturing
relationships with large real estate developers and asset managers; (ii)
continuing to pursue strategic acquisitions of other parking service companies;
and (iii) expanding its international activity, principally through joint
venture arrangements and consulting engagements. In addition, the Company
intends to achieve operating efficiencies through economies of scale by
leveraging its corporate infrastructure and its established presence in local
markets. Management also believes that privatization of parking and
parking-related services will provide significant opportunities in the future.

         Central Parking Corporation's principal executive offices are located
at 2401 21st Avenue South, Suite 200, Nashville, Tennessee 37212, and its
telephone number at that address is (615) 297-4255.

                               RECENT DEVELOPMENTS

ACQUISITION OF DIPLOMAT PARKING CORPORATION


         On October 1, 1997, subsequent to its fiscal year end, the Company
acquired the stock and certain assets of Diplomat Parking Corporation
("Diplomat") for approximately $21.7 million in cash and notes (the "Diplomat
Acquisition"). The acquisition was financed through the Company's revolving
credit facility. As of September 30, 1997, Diplomat operated 164 parking
facilities containing approximately 37,000 parking spaces, located primarily in
Washington, D.C. and Baltimore, Maryland.

ACQUISITION OF KINNEY SYSTEM HOLDING CORP.

         On February 12, 1998, the Company acquired Kinney System Holding Corp.
("Kinney"), a privately-held company headquartered in New York City, which the
Company believes is the largest operator of parking facilities in the New York
City metropolitan area and one of the largest parking companies in the
Northeastern United States (the "Kinney Acquisition" and, collectively with the
Diplomat Acquisition, the "Acquisitions"). Kinney has been in the parking
business for over 60 years. In addition to enhancing the Company's leading
market position in New York City, Kinney increases the Company's presence in a
number of other major markets such as Boston, Philadelphia and Washington, D.C.
and broadens its geographic coverage in the following nine states: Connecticut,
Florida, Kentucky, Maryland, Massachusetts, New Hampshire, New York,
Pennsylvania, and Virginia. Kinney provides both self-parking and valet parking
services, and provides parking related services such as facility design and
development and consulting services.

         On February 12, 1998, Kinney operated 403 parking facilities containing
approximately 168,800 spaces, including approximately 76,700 in the New York
City metropolitan area, 42,800 in Boston, 30,100 in Philadelphia and 10,300 in
Washington, D.C. Kinney's facility mix was comprised of 225 leased sites, 170
managed sites and 8 owned sites. The parking facilities operated by Kinney
include Yankee Stadium, the Waldorf-Astoria, Port Authority Bus Terminal, World
Financial Center and the General Motors Building in New York City, The
Ritz-Carlton--Boston, Government Center in Boston, Spectrum--Philadelphia, and
the Four Seasons Hotel of Washington, D.C.

         Consideration for the Kinney Acquisition was $208.8 million, including
$178.8 million in cash and other consideration and $37.0 million (882,422
shares) in Company Common Stock. In connection with this transaction, the
Company assumed $9.4 million in capitalized leases and refinanced $27.7 million
in existing Kinney debt. The purchase price is subject to adjustment based on
the outcome of an independent evaluation of Kinney's February 12, 1998 balance
sheet. The Company financed the Kinney Acquisition with borrowings under the New
Credit Facility described below.

NEW CREDIT FACILITY

         On February 11, 1998, the Company established a new credit facility
(the "New Credit Facility") providing for an aggregate availability of up to
$300 million, consisting of a five-year $200 million revolving credit facility,
including a sublimit of $25 million for standby letters of credit, and a $100
million five-year term loan. The New Credit Facility bears interest until June
30, 1998 at a rate of LIBOR plus 1.25%. On June 30, 1998, the interest rate on
the New Credit Facility and the commitment fee on the unused portion will revert
to a grid pricing based upon the achievement of various financial ratios. The
New Credit Facility contains certain covenants including those that require the
Company to maintain certain financial ratios, restrict further indebtedness, and
limit the amount of dividends payable. The Company used borrowings under the New
Credit Facility to replace the Company's prior revolving credit facility and to
finance the Kinney Acquisition. On March 18, 1998, the Company completed the
Original Offering and an offering of additional equity, from which the Company
obtained $195.3 million in proceeds. The Company repaid and terminated the $100
million term loan with proceeds from the offerings. The remaining $95.3 million
in proceeds was applied to reduce the outstanding balance under the $200
million revolving credit facility.

PUBLIC OFFERING OF THE COMPANY COMMON STOCK

         Concurrently with the Original Offering, the Company offered 1,875,000
shares of Company Common Stock pursuant to a registered public offering (the
"Company Common Stock Offering"), which along with over-allotments totalled
2,137,500 shares. The net proceeds to the Company from the Company Common Stock
Offering were approximately $89.3 million after deducting underwriting discounts
and commissions and estimated offering expenses.

                          CENTRAL PARKING FINANCE TRUST

         Central Parking Finance Trust (the "Trust") is a statutory business
trust created under Delaware law pursuant to (i) a trust agreement executed by
the Company (as Depositor), the Delaware Trustee and one of the Administrative
Trustees (each as defined herein) and (ii) the filing of a certificate of trust
with the Delaware Secretary of State on February 18, 1998. In connection with
the Original Offering, such trust agreement was amended and restated in its
entirety (as so amended and restated, the "Trust Agreement"). The Trust exists
for the sole purposes of (i) issuing and selling the Preferred Securities and
Common Securities, (ii) using the proceeds from the sale of the Preferred
Securities and Common Securities to acquire the Convertible Debentures issued by
the Company and (iii) engaging in only those other activities necessary or
incidental thereto. Accordingly, the Convertible Debentures are the sole assets
of the Trust, and payments under the Convertible Debentures will be the sole
revenue of the Trust. The Trust has a term of 30 years, but may dissolve earlier
as provided in the Trust Agreement.

         All of the Common Securities are directly or indirectly owned by the
Company. The Common Securities rank pari passu, and payments will be made
thereon pro rata, with the Preferred Securities, except that upon the occurrence
and continuance of a Declaration Event of Default (as defined herein) resulting
from an Event of Default under the Indenture, the rights of the Company as
holder of the Common Securities to payment in respect of distributions and
payments upon liquidation, redemption or otherwise will be subordinated to the
rights of the holders of the Preferred Securities. See "Description of the
Preferred Securities--Subordination of Common Securities." The Company has
acquired Common Securities in an aggregate liquidation amount equal to 3% of the
total capitalization of the Trust.

         The Trust's business and affairs are conducted by its trustees, which
were appointed by the Company as holder of the Common Securities. Pursuant to
the Trust Agreement, the number of trustees is initially five. Three of the
trustees (the "Administrative Trustees") are persons who are employees or
officers of, or affiliated with, the Company. A fourth trustee is a financial
institution unaffiliated with the Company that serves as property trustee (the
"Property Trustee") under the Trust Agreement. Chase Bank of Texas, National
Association is the Property Trustee until removed or replaced by the holder of
the Common Securities. See "Description of the Convertible Debentures." The
fifth trustee is a financial institution or an affiliate thereof which maintains
a principal place of business or residence in the State of Delaware (the
"Delaware Trustee"). Chase Manhattan Bank Delaware is the Delaware Trustee until
removed or replaced by the holder of the Common Securities. The Administrative
Trustees, the Property Trustee and the Delaware Trustee are referred to herein
as the "Issuer Trustees." Chase Bank of Texas, National Association also acts as
indenture trustee under the Guarantee (the "Guarantee Trustee") and as the
indenture trustee under the Indenture. See "Description of the Guarantee" and
"Description of the Convertible Debentures."

         The Property Trustee holds the title to the Convertible Debentures for
the benefit of the Trust and holders of the Preferred Securities and the Common
Securities and has the power to exercise all of the rights, powers and
privileges as the holder of the Convertible Debentures. In addition, the
Property Trustee maintains exclusive control of a segregated non-interest
bearing bank account (the "Property Account") to hold all payments made in
respect of the Convertible Debentures for the benefit of the Trust and holders
of the Preferred Securities and the Common Securities. The Property Trustee will
make payments of distributions and payments on liquidation, redemption and
otherwise to holders of the Preferred Securities and the Common Securities out
of funds from the Property Account. The Guarantee Trustee holds the Guarantee
for the benefit of the holders of the Preferred Securities. The Company, as the
holder of all the Common Securities, has the right to appoint, remove or replace
any Issuer Trustee and to increase or decrease the number of Issuer Trustees,
provided that the number of Issuer Trustees shall be at least three, the
majority of which will be Administrative Trustees. The duties and obligations of
obligations of the Issuer Trustees are governed by the Trust Agreement. The
rights of the holders of the Preferred Securities, including economic rights,
rights to information and voting rights, are as set forth in the Trust Agreement
and the Delaware Business Trust Act, as amended (the "Trust Act").

         The Company will pay all fees and expenses related to the Trust and the
offering of the Trust Securities and will pay, directly or indirectly, all
ongoing costs and expenses of the Trust. See "Description of the Convertible
Debentures." The principal corporate offices of the Trust are located at 2401
21st Avenue South, Suite 200, Nashville, TN 37212, and its telephone number is
(615) 297-4255.



                                 USE OF PROCEEDS

         Neither the Company nor the Trust will receive any proceeds from the
sale of the Offered Securities.

</TABLE>

         On May 8, 1998, the last reported sale price of the Company Common
Stock on the NYSE was $45.5625 per share. On May 8, 1998, there were
approximately 8,000 holders of the Company Common Stock, based on the number of
record holders and the number of individual participants represented by security
position listings.

         Since April 1997, the Company has distributed a quarterly cash dividend
of $0.015 per share of Company Common Stock. The Company had previously declared
a dividend of $0.013 per share of Company Common Stock following the end of each
quarter since its initial public offering in October 1995. The Board of
Directors currently intends to declare a cash dividend each quarter depending on
the Company's profitability and capital necessary to finance operations and
expansion. The Company reserves the right, however, to retain all or a
substantial portion of its earnings to finance the operation and expansion of
the Company's business. As a result, the future payment of dividends will depend
upon, among other things, the Company's profitability, capital requirements,
financial condition, growth, business opportunities, and other factors that the
Board of Directors may deem relevant, including restrictions in any
then-existing credit agreement. The New Credit Facility contains certain
restrictions on the Company's ability to pay dividends; however, the Company
does not believe these restrictions limit its ability to pay currently
anticipated cash dividends. In addition, the Preferred Securities prohibit the
payment of dividends on the Company Common Stock if the quarterly distributions
on the Preferred Securities are not made for any reason.



                 RATIO OF EARNINGS TO FIXED CHARGES (UNAUDITED)

         The following table sets forth the Company's ratio of earnings to fixed
charges on a historical basis for each of the three years in the period ended
September 30, 1997 and for the three-month periods ended December 31, 1996 and
December 31, 1997. The pro forma ratio of earnings to fixed charges gives effect
to the Acquisitions, including the incurrence of related indebtedness, the
Original Offering, the Company Common Stock Offering and the application of the
net proceeds to reduce indebtedness, as if they had occurred on October 1, 1996.

attributable to interest and preferred stock dividends. Earnings consist of
income before income taxes plus fixed charges (other than capitalized interest,
but including the amortization thereof).

                     DESCRIPTION OF THE PREFERRED SECURITIES

         The following summary of certain material terms and provisions of the
Preferred Securities and the Trust Agreement does not purport to be complete and
is subject to, and qualified in its entirety by reference to, all the provisions
of the Trust Agreement. The Preferred Securities were issued pursuant to the
terms of the Trust Agreement and the Trust Act. It is expected that at the time
this Shelf Registration Statement of which this Prospectus forms a part becomes
effective, the Trust Agreement will be qualified as an indenture under the Trust
Indenture Act. Chase Bank of Texas, National Association, as Property Trustee,
will act as indenture trustee for purposes of compliance with the Trust
Indenture Act. Capitalized terms not otherwise defined herein have the meanings
assigned to them in the Trust Agreement and those made part of the Trust
Agreement by the Trust Indenture Act.

GENERAL

         Pursuant to the terms of the Trust Agreement, the Issuer Trustees, on
behalf of the Trust, have issued the Trust Securities. The Preferred Securities
represent preferred, undivided beneficial ownership interests in the assets of
the Trust and entitle the holders thereof to a preference in certain
circumstances with respect to distributions and amounts payable on redemption or
liquidation over the Common Securities, as well as other benefits as described
in the Trust Agreement. The Preferred Securities will be issued in fully
registered form without interest coupons. The Common Securities represent
common, undivided beneficial interests in the assets of the Trust.

         All of the Common Securities are owned, directly or indirectly, by the
Company. The Common Securities rank pari passu, and payments will be made
thereon on a pro rata basis, with the Preferred Securities, except that upon the
occurrence of a Declaration Event of Default, the rights of the holders of the
Common Securities to receive payment of periodic distributions and payments upon
liquidation, redemption and otherwise were subordinated to the rights of the
holders of Preferred Securities. See "--Subordination of Common Securities."
Title to the Convertible Debentures is held by the Property Trustee for the
benefit of the holders of the Trust Securities. The Trust Agreement does not
permit the issuance by the Trust of any securities other than the Trust
Securities or the incurrence of any indebtedness by the Trust. The payment of
distributions out of moneys held by the Trust, and payments upon redemption of
the Preferred Securities or liquidation of the Trust, are guaranteed by the
Company to the extent described under "Description of the Guarantee." The
Guarantee is held by Chase Bank of Texas, National Association, the Guarantee
Trustee, for the benefit of the holders of the Preferred Securities. The
Guarantee does not cover payment of distributions when the Trust does not have
sufficient available funds to pay such distributions. In such event, the remedy
of a holder of Preferred Securities is to (i) vote to direct the Property
Trustee to enforce the Property Trustee's rights under the Convertible
Debentures or (ii) if the failure of the Trust to pay distributions is
attributable to the failure of the Company to pay interest or principal on the
Convertible Debentures, to institute a proceeding directly against the Company
for enforcement of payment to such holder of the principal of or interest on the
Convertible Debentures having a principal amount equal to the aggregate
liquidation amount of the Preferred Securities of such holder on or after the
respective due date specified in the Convertible Debentures. See "--Voting
Rights."

DISTRIBUTIONS

         Distributions on Preferred Securities are fixed at a rate per annum of
5 1/4% of the stated liquidation amount of $25 per Preferred Security.
Distributions in arrears for more than one quarter will bear interest thereon at
a rate per annum of 5 1/4% thereof compounded quarterly. The term "distribution"
as used herein includes any such interest (including any Additional Interest,
Compounded Interest and Liquidated Damages, if any (each as defined herein))
payable unless otherwise stated. The amount of distributions payable for any
period are computed on the basis of a 360-day year of twelve 30-day months.

         Distributions on the Preferred Securities are cumulative, accrue from
the date of initial issuance and are payable quarterly in arrears on each
January 1, April 1, July 1 and October 1, commencing July 1, 1998, when, as and
if available for payment, by the Property Trustee, except as otherwise described
below. So long as no Indenture Event of Default has occurred and is continuing,
the Company has the right under the Indenture to defer interest payments from
time to time on the Convertible Debentures for successive periods not exceeding
20 consecutive quarterly interest periods (each, an Extension Period) during
which no interest shall be due and payable; provided, that no such Extension
Period may extend beyond the maturity date of the Convertible Debentures. As a
consequence of such extension, quarterly distributions on the Preferred
Securities would be deferred (though such distributions would continue to accrue
with interest) during any such extended interest payment period. In the event
that the Company exercises this right, then, during such period, the Company has
agreed, among other things, (a) not to declare or pay dividends on, or make a
distribution with respect to, or redeem, purchase or acquire, or make a
liquidation payment with respect to, any of its capital stock (other than (i)
purchases or acquisitions of shares of Company Common Stock in connection with
the satisfaction by the Company of its obligations under any employee benefit
plans or the satisfaction by the Company of its obligations pursuant to any
contract or security requiring the Company to purchase shares of Company Common
Stock, (ii) as a result of a reclassification of the Company's capital stock or
the exchange or conversion of one class or series of the Company's capital stock
for another class or series of the Company's capital stock or (iii) the purchase
of fractional interests in shares of the Company's capital stock pursuant to the
conversion or exchange provisions of such




                                       17

<PAGE>   18



capital stock or the security being converted or exchanged (or make any
guarantee payments with respect to the foregoing)), (b) not to make any payment
of interest, principal of or premium, if any, on, or repay, repurchase or redeem
any debt securities (including guarantees) issued by the Company that rank pari
passu with or junior to the Convertible Debentures, and (c) not to make any
guarantee payments with respect to the foregoing (other than pursuant to the
Guarantee). Prior to the termination of any such Extension Period, the Company
may further extend such Extension Period; provided, that such Extension Period,
together with all previous and further extensions thereof, may not exceed 20
consecutive quarters and that such Extension Period may not extend beyond the
maturity date of the Convertible Debentures. Upon the termination of any
Extension Period and the payment of all amounts then due, the Company may select
a new Extension Period, subject to the above requirements. Consequently, there
could be multiple Extension Periods of varying lengths throughout the term of
the Convertible Debentures. See "Description of the Convertible
Debentures--Interest" and "Description of the Convertible Debentures--Option to
Extend Interest Payment Periods." If distributions are deferred, the deferred
distributions and accrued interest thereon shall be paid to the holders of
record of Preferred Securities as they appear on the books and records of the
Trust on the record date next following the termination of such deferral period.

         The Company has no current intention to exercise its right to defer
payments of interest by extending the interest payment period on the Convertible
Debentures.

         Distributions on the Preferred Securities will be made to the extent
that the Trust has funds available for the payment of such distributions in the
Property Account. Amounts available to the Trust for distribution to the holders
of the Preferred Securities will be limited to payments received by the Trust
from the Company for the Convertible Debentures. See "Description of the
Convertible Debentures." The payment of distributions out of funds held by the
Trust is guaranteed by the Company on a limited basis as set forth under
"Description of the Guarantee."

         Distributions on the Preferred Securities will be payable to the
holders thereof as they appear on the books and records of the Trust on the
relevant record dates, which will be fifteen days prior to the relevant payment
dates. Subject to any applicable laws and regulations and the provisions of the
Trust Agreement, each such payment will be made as described under "--Book-Entry
Only Issuance-The Depository Trust Company" below. In the event that any date on
which distributions are payable on the Preferred Securities is not a Business
Day, payment of the distribution payable on such date will be made on the next
succeeding day which is a Business Day (without any distribution or other
payment in respect of any such delay) except that, if such Business Day is in
the next succeeding calendar year, such payment shall be made on the immediately
preceding Business Day, in each case with the same force and effect as if made
on such date. A "Business Day" shall mean any day other than a day on which
banking institutions in New York, New York or in Wilmington, Delaware are
authorized or required by law to close.

CONVERSION RIGHTS

         General. Preferred Securities are convertible at any time prior to 5:00
p.m. (New York City time) on the Business Day immediately preceding the date of
repayment of such Preferred Securities, whether at maturity or upon redemption
(either at the option of the Company or pursuant to a Tax Event), at the option
of the holder thereof and in the manner described below, into shares of Company
Common Stock at an initial conversion rate of 0.4545 shares of Company Common
Stock for each Preferred Security (equivalent to a conversion price of $55.00
per share of Company Common Stock), subject to adjustment as described below.
The Trust covenants in the Trust Agreement not to convert Convertible Debentures
held by it except pursuant to a notice of conversion delivered to the Property
Trustee, as conversion agent (the "Conversion Agent"), by a holder of Preferred
Securities.

         A holder of a Preferred Security wishing to exercise its conversion
right shall deliver an irrevocable conversion notice, together, if the Preferred
Security is a Certificated Security (as defined herein), with such Certificated
Security, to the Conversion Agent which shall, on behalf of such holder,
exchange such Preferred Security for a portion of the Convertible Debentures and
immediately convert such Convertible Debentures into Company Common Stock.
Holders may obtain copies of the required form of the conversion notice from the
Conversion Agent. Procedures for converting book-entry Preferred Securities into
shares of Company Common Stock will differ, as described under "--Book-Entry
Only Issuance-The Depository Trust Company."

         Holders of Preferred Securities at 5:00 p.m. (New York City time) on a
distribution record date will be entitled to receive the distribution payable on
such Preferred Securities on the corresponding distribution payment date
notwithstanding the conversion of such Preferred Securities following such
distribution record date but prior to such distribution payment date. Except as
provided in the immediately preceding sentence, neither the Trust nor the
Company will make, or be required to make, any payment, allowance or adjustment
for accumulated and unpaid distributions, whether or not in arrears, on
converted Preferred Securities. The Company will make no payment or allowance
for distributions on the shares of Company Common Stock issued upon such
conversion, except to the extent that such shares of Company Common Stock are
held of record on the record date for any such distributions. Each conversion
will be deemed to have been effected immediately prior to 5:00 p.m. (New York
City time) on the day on which the related conversion notice was received by the
Conversion Agent.



                                       18

<PAGE>   19



         Shares of Company Common Stock issued upon conversion of Preferred
Securities will be validly issued, fully paid and non-assessable. No fractional
shares of Company Common Stock will be issued as a result of conversion, but in
lieu thereof such fractional interest will be paid by the Company in cash based
on the last reported sale price of Company Common Stock on the date such
Preferred Securities are surrendered for conversion.

         Conversion Price Adjustments--General. The conversion price is subject
to adjustment in certain events, including (a) the issuance of shares of Company
Common Stock as a dividend or a distribution with respect to Company Common
Stock, (b) subdivisions, combinations and reclassifications of Company Common
Stock, (c) the issuance to all holders of Company Common Stock of rights or
warrants entitling them (for a period not exceeding 45 days) to subscribe for
shares of Company Common Stock at less than the then Current Market Price (as
defined below) of the Company Common Stock, (d) the distribution to holders of
Company Common Stock of evidences of indebtedness of the Company, securities or
capital stock, cash or assets (including securities, but excluding those rights,
warrants, dividends and distributions referred to above and dividends and
distributions paid exclusively in cash), (e) the payment of dividends (and other
distributions) on Company Common Stock paid exclusively in cash, excluding cash
dividends if the annualized per share amount thereof does not exceed 20% of the
Current Market Price of Company Common Stock as of the trading day immediately
preceding the date of declaration of such dividend, and (f) payment to holders
of Company Common Stock in respect of a tender or exchange offer (other than an
odd-lot offer) by the Company for Company Common Stock at a price in excess of
110% of the then Current Market Price of Company Common Stock as of the trading
day next succeeding the last date tenders or exchanges may be made pursuant to
such tender or exchange offer. The term "Current Market Price" means the average
of the daily closing prices for the five consecutive trading days selected by
the Company commencing not more than 20 trading days before, and ending not
later than, the earlier of the day in question or, if applicable, the day before
the "ex" date with respect to the issuance or distribution in question.

         The Company from time to time may reduce the conversion price of the
Convertible Debentures (and thus the conversion price of the Preferred
Securities) by any amount selected by the Company for any period of at least 20
days, in which case the Company shall give at least 15 days' notice of such
reduction. The Company may, at its option, make such reductions in the
conversion price, in addition to those set forth above, as the Company's Board
of Directors deems advisable to avoid or diminish any income tax to holders of
Company Common Stock resulting from any dividend or distribution of stock (or
rights to acquire stock) or from any event treated as such for income tax
purposes. See "United States Federal Income Taxation--Adjustment of Conversion
Price."

         No adjustment of the conversion price will be made upon the issuance of
any shares of Company Common Stock pursuant to any present or future plan
providing for the reinvestment of dividends or interest payable on securities of
the Company and the investment of additional optional amounts in shares of
Company Common Stock under any such plan. No adjustment in the conversion price
will be required unless such adjustment would require a change of at least one
percent (1%) in the price then in effect; provided, however, that any adjustment
that would not be required to be made shall be carried forward and taken into
account in any subsequent adjustment. If any action would require adjustment of
the conversion price pursuant to more than one of the provisions described
above, only one adjustment shall be made and such adjustment shall be the amount
of adjustment that has the highest absolute value to the holder of the Preferred
Securities.

         Conversion Price Adjustments--Merger, Consolidation or Sale of Assets
of the Company. If any Fundamental Change (as defined below) occurs, then the
conversion price in effect will be adjusted immediately after such Fundamental
Change as described below. In addition, in the event of a Common Stock
Fundamental Change (as defined below), each Preferred Security shall be
convertible solely into common stock of the kind received by holders of Company
Common Stock as a result of such Common Stock Fundamental Change.

         In the event that the Company is party to any transaction (including,
without limitation, a merger other than a merger that does not result in a
reclassification, conversion, exchange or cancellation of Company Common Stock),
consolidation, sale of all or substantially all of the assets of the Company,
recapitalization or reclassification of Company Common Stock (other than a
change in par value, or from par value to no par value, or from no par value to
par value or as a result of a subdivision or combination of Company Common
Stock) or any compulsory share exchange (each of the foregoing being referred to
as a "Transaction"), in each case, as a result of which shares of Company Common
Stock shall be converted into the right to receive, or shall be exchanged for,
(i) in the case of any Transaction other than a Transaction involving a Common
Stock Fundamental Change (and subject to funds being legally available for such
purpose under applicable law at the time of such conversion), securities, cash
or other property, each Preferred Security shall thereafter be convertible into
the kind and, in the case of a Transaction which does not involve a Fundamental
Change, amount of securities, cash and other property receivable upon the
consummation of such Transaction by a holder of that number of shares of Company
Common Stock into which a Preferred Security was convertible immediately prior
to such Transaction, or (ii) in the case of a Transaction involving a Common
Stock Fundamental Change, common stock, each Preferred Security shall thereafter
be convertible (in the manner described therein) into common stock of the kind
received by holders of Company Common Stock (but in each case after giving
effect to any adjustment discussed below relating to a Fundamental Change if
such Transaction constitutes a Fundamental Change). The holders of Preferred
Securities have no voting rights with respect to any Transaction.




                                       19

<PAGE>   20



         The conversion price in the case of any Transaction involving a
Fundamental Change will be adjusted immediately after such Fundamental Change:

                  (i) in the case of a Non-Stock Fundamental Change (as defined
         below), the conversion price of the Preferred Securities will thereupon
         become the lower of (A) the conversion price in effect immediately
         prior to such Non-Stock Fundamental Change, but after giving effect to
         any other prior adjustments effected pursuant to the preceding
         paragraphs, and (B) the greater of the Applicable Price (as defined
         below) or the then applicable Reference Market Price (as defined below)
         plus any then-accrued and unpaid distributions on one Preferred
         Security; and

                  (ii) in the case of a Common Stock Fundamental Change, the
         conversion price of the Preferred Securities in effect immediately
         prior to such Common Stock Fundamental Change, but after giving effect
         to any other prior adjustments effected pursuant to the preceding
         paragraphs, will thereupon be adjusted by multiplying such conversion
         price by a fraction of which the numerator will be the Purchaser Stock
         Price (as defined below) and the denominator will be the Applicable
         Price; provided, however, that in the event of a Common Stock
         Fundamental Change in which (A) 100% of the value of the consideration
         received by a holder of Company Common Stock is common stock of the
         successor, acquirer, or other third party (and cash, if any, is paid
         only with respect to any fractional interests in such common stock
         resulting from such Common Stock Fundamental Change) and (B) all
         Company Common Stock will have been exchanged for, converted into, or
         acquired for common stock (and cash with respect to fractional
         interests) of the successor, acquirer, or other third party, the
         conversion price of the Preferred Securities in effect immediately
         prior to such Common Stock Fundamental Change will thereupon be
         adjusted by multiplying such conversion price by a fraction of which
         the numerator will be one and the denominator will be the number of
         shares of common stock of the successor, acquirer, or other third party
         received by a holder of one share of Company Common Stock as a result
         of such Common Stock Fundamental Change.

         The foregoing conversion price adjustments are designed, in certain
circumstances, to reduce the conversion price that would be applicable in
"Fundamental Change" Transactions where all or substantially all the Company
Common Stock is converted into securities, cash, or property and not more than
50% of the value received by the holders of Company Common Stock consists of
stock listed or admitted for listing subject to notice of issuance on the NYSE
or a national securities exchange or quoted on the Nasdaq National Market (a
Non-Stock Fundamental Change, as defined below). Such reduction would result in
an increase in the amount of the securities, cash, or property into which each
Preferred Security is convertible over that which would have been obtained in
the absence of such conversion price adjustment.

         In a Non-Stock Fundamental Change Transaction where the initial value
received per share of Company Common Stock (measured as described in the
definition of Applicable Price below) is lower than the then applicable
conversion price of a Preferred Security but greater than or equal to the
"Reference Market Price," the conversion price will be adjusted as described
above with the effect that each Preferred Security will be convertible into
securities, cash or property of the same type received by the holders of Company
Common Stock in the Transaction but in an amount per Preferred Security that
would at the time of the Transaction have had a value equal to the Liquidation
Preference.


         In a Non-Stock Fundamental Change Transaction where the initial value
received per share of Company Common Stock (measured as described in the
definition of Applicable Price) is lower than both the conversion price of a
Preferred Security in effect prior to any adjustment described above and the
Reference Market Price, the conversion price will be adjusted as described above
but calculated as though such initial value had been the Reference Market Price.

         In a Fundamental Change Transaction where all or substantially all the
Company Common Stock is converted into securities, cash, or property and more
than 50% of the value received by the holders of Company Common Stock consist of
listed or Nasdaq National Market traded common stock (a Common Stock Fundamental
Change, as defined below), the foregoing adjustments are designed to provide in
effect that (a) where Company Common Stock is converted partly into such common
stock and partly into other securities, cash, or property, each Preferred
Security will be convertible solely into a number of shares of such common stock
determined so that the initial value of such shares (measured as described in
the definition of "Purchaser Stock Price" below) equals the value of the shares
of Company Common Stock into which such Preferred Security was convertible
immediately before the Transaction (measured as aforesaid) and (b) where Company
Common Stock is converted solely into such common stock, each Preferred Security
will be convertible into the same number of shares of such common stock
receivable by a holder of the number of shares of Company Common Stock into
which such Preferred Security was convertible immediately before such
Transaction.

         The term "Applicable Price" means (i) in the case of a Non-Stock
Fundamental Change in which the holders of the Company Common Stock receive only
cash, the amount of cash received by the holder of one share of Company Common
Stock and (ii) in the event of any other Non-Stock Fundamental Change or any
Common Stock Fundamental Change, the average of the Closing Prices (as defined
below) for the Company Common Stock during the ten trading




                                       20

<PAGE>   21



days prior to the record date for the determination of the holders of Company
Common Stock entitled to receive such securities, cash, or other property in
connection with such Non-Stock Fundamental Change or Common Stock Fundamental
Change or, if there is no such record date, the date upon which the holders of
the Company Common Stock shall have the right to receive such securities, cash,
or other property (such record date or distribution date being hereinafter
referred to as the "Entitlement Date"), in each case as adjusted in good faith
by the Company to appropriately reflect any of the events referred to in clauses
(i) through (vi) of the first paragraph under "--Conversion Price
Adjustments--General."

         The term "Closing Price" means on any day the reported last sale price
on such day or in case no sale takes place on such day, the average of the
reported closing bid and asked prices in each case on the NYSE Consolidated
Transactions Tape or, if the stock is not listed or admitted to trading on the
NYSE, on the principal national securities exchange on which such stock is
listed or admitted to trading or, if not listed or admitted to trading on any
national securities exchange, the average of the closing bid and asked prices as
furnished by any NYSE member firm, selected by the Debenture Trustee for that
purpose.

         The term "Common Stock Fundamental Change" means any Fundamental Change
in which more than 50% of the value (as determined in good faith by the Board of
Directors of the Company) of the consideration received by holders of Company
Common Stock consists of common stock that for each of the ten consecutive
trading days prior to the Entitlement Date has been admitted for listing or
admitted for listing subject to notice of issuance on a national securities
exchange or quoted on the Nasdaq National Market; provided, however, that a
Fundamental Change shall not be a Common Stock Fundamental Change unless either
(i) the Company continues to exist after the occurrence of such Fundamental
Change and the outstanding Preferred Securities continue to exist as outstanding
Preferred Securities or (ii) not later than the occurrence of such Fundamental
Change, the outstanding Preferred Securities are converted into or exchanged for
shares of convertible preferred stock of an entity succeeding to the business of
the Company or a subsidiary thereof, which convertible preferred stock has
powers, preferences, and relative, participating, optional, or other rights, and
qualifications, limitations, and restrictions, substantially similar to those of
the Preferred Securities.

         The term "Fundamental Change" means the occurrence of any Transaction
or event in connection with a plan pursuant to which all or substantially all of
the Company Common Stock shall be exchanged for, converted into, acquired for,
or constitute solely the right to receive securities, cash, or other property
(whether by means of an exchange offer, liquidation, tender offer,
consolidation, merger, combination, reclassification, recapitalization, or
otherwise), provided, that, in the case of a plan involving more than one such
Transaction or event, for purposes of adjustment of the conversion price, such
Fundamental Change shall be deemed to have occurred when substantially all of
the Company Common Stock shall be exchanged for, converted into, or acquired for
or constitute solely the right to receive securities, cash, or other property,
but the adjustment shall be based upon the consideration that a holder of
Company Common Stock received in such Transaction or event as a result of which
more than 50% of the Company Common Stock shall have been exchanged for,
converted into, or acquired for or constitute solely the right to receive
securities, cash, or other property. The term "Non-Stock Fundamental Change"
means any Fundamental Change other than a Common Stock Fundamental Change.

         The term "Purchaser Stock Price" means, with respect to any Common
Stock Fundamental Change, the average of the Closing Prices for the common stock
received in such Common Stock Fundamental Change for the ten consecutive trading
days prior to and including the Entitlement Date, as adjusted in good faith by
the Company to appropriately reflect any of the events referred to in clauses
(i) through (vi) of the first paragraph under "--Conversion Price
Adjustments--General."

         The term "Reference Market Price" shall initially mean $29.37 (which is
an amount equal to 66 2/3% of the reported last sale price for Company Common
Stock on the NYSE Consolidated Transactions Tape on March 12, 1998) and in the
event of any adjustment of the conversion price other than as a result of a
Non-Stock Fundamental Change, the Reference Market Price shall also be adjusted
so that the ratio of the Reference Market Price to the conversion price after
giving effect to any such adjustment shall always be the same as the ratio of
the initial Reference Market Price to the initial conversion price of the
Preferred Securities.

         Conversion price adjustments or omissions in making such adjustments
may, under certain circumstances, be deemed to be distributions that could be
taxable as dividends to holders of Preferred Securities or to the holders of
Company Common Stock. See "United States Federal Income Taxation--Adjustment of
Conversion Price."

REDEMPTION

         The Convertible Debentures mature on April 1, 2028, and may be
redeemed, in whole or in part, at any time after April 3, 2001 or at any time in
certain circumstances upon the occurrence of a Tax Event. Upon the repayment of
the Convertible Debentures, whether at maturity or upon redemption (either at
the option of the Company or pursuant to a Tax Event), the proceeds from such
repayment shall simultaneously be applied to redeem Trust Securities having an
aggregate liquidation amount equal to the Convertible Debentures so repaid or
redeemed at the applicable Redemption Price, together with accrued and unpaid
distributions through the date of redemption; provided, that holders




                                       21

<PAGE>   22



of the Trust Securities shall be given not less than 30 nor more than 60 days'
notice of such redemption. See "--Special Event Redemption or Distribution,"
"--Redemption Procedures," "Description of the Convertible Debentures--General,"
"Description of the Convertible Debentures--Mandatory Redemption" and
"Description of the Convertible Debentures-- Optional Redemption."

SPECIAL EVENT REDEMPTION OR DISTRIBUTION

         If, at any time, a Tax Event or an Investment Company Event (either
event, a "Special Event") shall occur and be continuing, the Trust shall, unless
the Convertible Debentures are redeemed in the limited circumstances described
below, be dissolved with the result that, after satisfaction of creditors, if
any, of the Trust, Convertible Debentures with an aggregate principal amount
equal to the aggregate stated liquidation amount of, with an interest rate
identical to the distribution rate of, and accrued and unpaid interest equal to
accrued and unpaid distributions on, and having the same record date for payment
as the Preferred Securities and the Common Securities outstanding at such time
would be distributed on a pro rata basis to the holders of the Preferred
Securities and the Common Securities in liquidation of such holders' interests
in the Trust, within 90 days following the occurrence of such Special Event;
provided, however, that in the case of the occurrence of a Tax Event, as a
condition of such dissolution and distribution, the Property Trustee, on behalf
of the Trust, shall have received an opinion of nationally recognized
independent tax counsel experienced in such matters (a "No Recognition
Opinion"), which opinion may rely on published revenue rulings of the Internal
Revenue Service, to the effect that the holders of the Preferred Securities will
not recognize any income, gain or loss for United States federal income tax
purposes as a result of such dissolution and distribution of Convertible
Debentures; and, provided, further, that if at the time there is available to
the Trust the opportunity to eliminate, within such 90-day period, the Special
Event by taking some ministerial action, such as filing a form or making an
election, or pursuing some other similar reasonable measure which in the sole
judgment of the Company has or will cause no adverse effect on the Trust, the
Company or the holders of the Trust Securities and will involve no material
cost, the Trust will pursue such measure in lieu of dissolution. Furthermore, if
in the case of the occurrence of a Tax Event, (i) the Property Trustee, on
behalf of the Trust, has received an opinion (a "Redemption Tax Opinion") of
nationally recognized independent tax counsel experienced in such matters that,
as a result of a Tax Event, there is more than an insubstantial risk that the
Company would be precluded from deducting the interest on the Convertible
Debentures for United States federal income tax purposes even if the Convertible
Debentures were distributed to the holders of Preferred Securities and Common
Securities in liquidation of such holders' interests in the Trust as described
above or (ii) the Property Trustee shall have been informed by such tax counsel
that a No Recognition Opinion cannot be delivered to the Trust, the Company
shall have the right, upon not less than 30 nor more than 60 days' notice, to
redeem the Convertible Debentures, in whole (but not in part) for cash within 90
days following the occurrence of such Tax Event, and promptly following such
redemption, the Preferred Securities and Common Securities will be redeemed by
the Trust at the Redemption Price; provided, however, that if at the time there
is available to the Company or the Trust the opportunity to eliminate, within
such 90-day period, the Tax Event by taking some ministerial action, such as
filing a form or making an election, or pursuing some other similar reasonable
measure which in the sole judgment of the Company has or will cause no adverse
effect on the Trust, the Company or the holders of the Trust Securities and will
involve no material cost, the Company or the Trust will pursue such measure in
lieu of redemption.

         "Tax Event" means that the Property Trustee, on behalf of the Trust,
shall have received an opinion of nationally recognized independent tax counsel
experienced in such matters (a "Dissolution Tax Opinion") to the effect that as
a result of (a) any amendment to, or change (including any announced prospective
change) in, the laws (or any regulations thereunder) of the United States or any
political subdivision or taxing authority thereof or therein, (b) any amendment
to, or change in, an interpretation or application of any such laws or
regulations by any legislative body, court, governmental agency or regulatory
authority (including the enactment of any legislation and the publication of any
judicial decision or regulatory determination), (c) any interpretation or
pronouncement that provides for a position with respect to such laws or
regulations that differs from the theretofore generally accepted position or (d)
any action taken by any governmental agency or regulatory authority, which
amendment or change is enacted, promulgated, issued or announced or which
interpretation or pronouncement is issued or announced or which action is taken,
in each case on or after the date of this Prospectus (collectively, a "Change in
Tax Law"), there is more than an insubstantial risk that (i) the Trust is, or
will be within 90 days of the date thereof, subject to United States federal
income tax with respect to income accrued or received on the Convertible
Debentures, (ii) the Trust is, or will be within 90 days of the date thereof,
subject to more than a de minimis amount of other taxes, duties or other
governmental charges or (iii) interest payable by the Company to the Trust on
the Convertible Debentures is not, or within 90 days of the date thereof will
not be, deductible by the Company for United States federal income tax purposes.
Notwithstanding anything in the previous sentence to the contrary, a Tax Event
shall not include any Change in Tax Law that requires the Company for United
States federal income tax purposes to defer taking a deduction for any OID that
accrues with respect to the Convertible Debentures until the interest payment
related to such OID is paid by the Company in money; provided, that such Change
in Tax Law does not create more than an insubstantial risk that the Company will
be prevented from taking a deduction for OID accruing with respect to the
Convertible Debentures at a date that is no later than the date the interest
payment related to such OID is actually paid by the Company in money.

         "Investment Company Event" means that the Property Trustee, on behalf
of the Trust, shall have received an opinion of nationally recognized
independent counsel experienced in practice under the Investment Company Act of




                                       22

<PAGE>   23



1940, as amended (the "1940 Act"), that as a result of the occurrence of a
change in law or regulation or a change in interpretation or application of law
or regulation by any legislative body, court, governmental agency or regulatory
authority (a "Change in 1940 Act Law"), there is more than an insubstantial risk
that the Trust is or will be considered an "investment company" which is
required to be registered under the 1940 Act, which Change in 1940 Act Law
becomes effective on or after the date hereof.

         On the date fixed for any distribution of Convertible Debentures, upon
dissolution of the Trust, (i) the Preferred Securities and the Common Securities
will no longer be deemed to be outstanding, (ii) DTC or its nominee, as the
record holder of such Preferred Securities, will receive a registered global
certificate or certificates representing the Convertible Debentures to be
delivered upon such distribution and (iii) certificates representing Trust
Securities not held by DTC or its nominee will be deemed to represent beneficial
interests in the Convertible Debentures having an aggregate principal amount
equal to the stated liquidation amount of, and bearing accrued and unpaid
interest equal to accrued and unpaid distributions on, such Preferred Securities
until such certificates are presented to the Company or its agent for transfer
or reissuance.

         There can be no assurance as to the market price for the Convertible
Debentures which may be distributed in exchange for Trust Securities if a
dissolution and liquidation of the Trust were to occur. Accordingly, the
Convertible Debentures which the investor may subsequently receive on
dissolution and liquidation of the Trust may trade at a discount to the price of
the Trust Securities exchanged. If the Convertible Debentures are distributed to
the holders of the Preferred Securities, the Company will use its best efforts
to cause the Convertible Debentures to be listed on the NYSE or on any such
other national securities exchange or similar organization as the Preferred
Securities are then listed or quoted.

         At any time, the Company has the right to dissolve the Trust and, after
satisfaction of the liabilities of creditors of the Trust as provided by
applicable law, cause the Convertible Debentures to be distributed to the
holders of the Preferred Securities in dissolution of the Trust. Under current
United States federal income tax law and interpretations and assuming, as
expected, the Trust is treated as a grantor trust, a distribution of the
Convertible Debentures should not be a taxable event to the Trust and holders of
the Preferred Securities. Should there be a change in law, a change in legal
interpretation, a Special Event or other circumstances, however, the
distribution could be a taxable event to holders of the Preferred Securities.
See "United States Federal Income Taxation--Receipt of Convertible Debentures or
Cash upon Liquidation of the Trust."

REDEMPTION PROCEDURES

         The Trust may not redeem fewer than all of the outstanding Preferred
Securities unless all accrued and unpaid distributions have been paid in cash on
all Preferred Securities for all quarterly distribution periods terminating on
or prior to the date of redemption.

         In the event of any redemption in part, the Trust is not required to
(i) issue, register the transfer of or exchange any Preferred Security during a
period beginning at the opening of business 15 days before any selection for
redemption of Preferred Securities and ending at the close of business on the
earliest date in which the relevant notice of redemption is deemed to have been
given to all holders of Preferred Securities to be so redeemed and (ii) register
the transfer of or exchange any Preferred Securities so selected for redemption,
in whole or in part, except for the unredeemed portion of any Preferred
Securities being redeemed in part.

         If the Trust gives a notice of redemption in respect of Preferred
Securities (which notice will be irrevocable), and if the Company has paid to
the Property Trustee a sufficient amount of cash in connection with the related
redemption or maturity of the Convertible Debentures, then, by 12:00 noon, New
York City time, on the redemption date, the Trust will irrevocably deposit with
DTC funds sufficient to pay the amount payable on redemption of all book-entry
certificates and will give DTC irrevocable instructions and authority to pay
such amount in respect of Preferred Securities represented by the Global
Certificates (as defined herein) and will irrevocably deposit with the paying
agent for the Preferred Securities funds sufficient to pay such amount in
respect of any Certificated Securities and will give such paying agent
irrevocable instructions and authority to pay such amount to the holders of
Certificated Securities upon surrender of their certificates. If notice of
redemption shall have been given and funds are deposited as required, then upon
the date of such deposit, all rights of holders of such Preferred Securities so
called for redemption will cease, except (i) the right of the holders of such
Preferred Securities to receive the Redemption Price, but without interest on
such Redemption Price, and (ii) the right to convert such Preferred Securities
into Company Common Stock in the manner described herein through the close of
business on the date fixed for redemption. In the event that any date fixed for
redemption of Preferred Securities is not a Business Day, then payment of the
amount payable on such date will be made on the next succeeding day which is a
Business Day (without any interest or other payment in respect of any such
delay), except that, if such Business Day falls in the next calendar year, such
payment will be made on the immediately preceding Business Day. In the event
that payment of the Redemption Price in respect of Preferred Securities is
improperly withheld or refused and not paid either by the Trust or by the
Company pursuant to the Guarantee described under "Description of the
Guarantee," distributions on such Preferred Securities will continue to accrue
at the then applicable rate, from the original redemption date to the date of
payment, in which case the actual




                                       23

<PAGE>   24



payment date will be considered the date fixed for redemption for purposes of
calculating the amount payable upon redemption (other than for calculating any
premium).

         Subject to the foregoing and applicable law (including, without
limitation, United States federal securities laws), the Company or its
subsidiaries may at any time and from time to time purchase outstanding
Preferred Securities by tender, in the open market or by private agreement.

         If less than all of the Preferred Securities and Common Securities
issued by the Trust are to be redeemed on a redemption date, then the aggregate
liquidation preference of such Preferred Securities and Common Securities to be
redeemed shall be allocated pro rata among the Preferred Securities and the
Common Securities. The particular Preferred Securities to be redeemed shall be
selected not more than 60 days prior to the redemption date by the Property
Trustee from the outstanding Preferred Securities not previously called for
redemption, by lot or by such method as the Property Trustee shall deem fair and
appropriate and which may provide for the selection for redemption of portions
(equal to $25 or an integral multiple of $25 in excess thereof) of the
liquidation preference of the Preferred Securities. The Property Trustee shall
promptly notify the Conversion Agent in writing of the Preferred Securities
selected for redemption and, in the case of any Preferred Securities selected
for partial redemption, the liquidation preference thereof to be redeemed; it
being understood that, in the case of Preferred Securities held by DTC (or any
successor) or its nominee, the distribution of the proceeds of such redemption
will be made in accordance with the procedures of DTC or its nominee. For all
purposes of the Trust Agreement, unless the context otherwise requires, all
provisions relating to the redemption of Preferred Securities shall relate, in
the case of any Preferred Securities redeemed or to be redeemed only in part, to
the portion of the aggregate liquidation preference of Preferred Securities
which has been or is to be redeemed.

         Notice of any redemption of Convertible Debentures will be mailed at
least 30 days but not more than 60 days before the redemption date to each
holder of Convertible Debentures to be redeemed at its registered address.
Unless the Company defaults in payment of the Redemption Price, on and after the
redemption date interest shall cease to accrue on such Convertible Debentures or
portions thereof called for redemption.

SUBORDINATION OF COMMON SECURITIES

         Payment of distributions on, and the amount payable upon redemption of,
the Trust Securities, as applicable, shall be made pro rata based on the
liquidation amount of the Trust Securities; provided, however, that, if on any
distribution date or redemption date a Declaration Event of Default shall have
occurred and be continuing, no payment of any distribution on, or amount payable
upon redemption of, any Common Security, and no other payment on account of the
redemption, liquidation or other acquisition of Common Securities, shall be made
unless payment in full in cash of all accumulated and unpaid distributions on
all outstanding Preferred Securities for all distribution periods terminating on
or prior thereto, or in the case of payment of the amount payable upon
redemption of the Preferred Securities, the full amount of such amount in
respect of all outstanding Preferred Securities shall have been made or provided
for, and all funds available to the Property Trustee shall first be applied to
the payment in full in cash of all distributions on, or the amount payable upon
redemption of, Preferred Securities then due and payable.

         In the case of any Declaration Event of Default, the holder of Common
Securities will be deemed to have waived any such Declaration Event of Default
until all such Declaration Events of Default with respect to the Preferred
Securities have been cured, waived or otherwise eliminated. Until any such
Declaration Events of Default with respect to the Preferred Securities have been
so cured, waived or otherwise eliminated, the Property Trustee shall act solely
on behalf of the holders of the Preferred Securities and not the holder of the
Common Securities, and only the holders of the Preferred Securities will have
the right to direct the Property Trustee to act on their behalf.

LIQUIDATION DISTRIBUTION UPON DISSOLUTION

         In the event of any voluntary or involuntary liquidation, dissolution,
winding-up or termination of the Trust (each a "Liquidation"), the then holders
of the Preferred Securities will be entitled to receive out of the assets of the
Trust, after satisfaction of liabilities to creditors, distributions in an
amount equal to the aggregate of the stated liquidation amount of $25 per
Preferred Security plus accrued and unpaid distributions thereon to the date of
payment (the "Liquidation Distribution"), unless, in connection with such
Liquidation, Convertible Debentures in an aggregate stated principal amount
equal to the aggregate stated liquidation amount of, with an interest rate
identical to the distribution rate of, and accrued and unpaid interest equal to
accrued and unpaid distributions on, the Preferred Securities have been
distributed on a pro rata basis to the holders of the Preferred Securities.

         If, upon any such Liquidation, the Liquidation Distribution can be paid
only in part because the Trust has insufficient assets available to pay in full
the aggregate Liquidation Distribution, then the amounts payable directly by the
Trust on the Preferred Securities shall be paid on a pro rata basis. The holders
of the Common Securities will be entitled to receive distributions upon any such
dissolution pro rata with the holders of the Preferred Securities, except that
if a Declaration Event of Default has occurred and is continuing, the Preferred
Securities shall have a preference over the Common Securities with regard to
such distributions.




                                       24

<PAGE>   25



         Pursuant to the Trust Agreement, the Trust shall terminate (i) on April
1, 2028, the expiration of the term of the Trust, (ii) upon the bankruptcy of
the Company, (iii) upon the filing of a certificate of dissolution or the
equivalent with respect to the Company, the filing of a certificate of
cancellation with respect to the Trust after having obtained the consent of at
least a majority in liquidation amount of the Trust Securities, voting together
as a single class, to file such certificate of cancellation, or the revocation
of the charter of the Company and the expiration of 90 days after the date of
revocation without a reinstatement thereof, (iv) upon the distribution of all of
the Convertible Debentures upon the occurrence of a Special Event, except in the
case of a Tax Event that has occurred and is continuing following which the
Company has elected to pay any additional sums such that the net amount received
by holders of Preferred Securities in respect of Distributions is not reduced as
a result of such Tax Event and the Company has not revoked any such election or
failed to make such payments, (v) upon the entry of a decree of a judicial
dissolution of the Company or the Trust, or (vi) upon the redemption, conversion
or exchange of all the Trust Securities and the amounts necessary for
redemption, conversion or exchange thereof, including any Additional Interest,
Compounded Interest and Liquidated Damages, if any, shall have been paid to the
holders in accordance with the terms of the Trust Securities.

MERGER OR CONSOLIDATION OF ISSUER TRUSTEES

         Any entity into which the Property Trustee, the Delaware Trustee or any
Administrative Trustee that is not a natural person may be merged or converted
or with which it may be consolidated, or any entity resulting from any merger,
conversion or consolidation to which such Issuer Trustee shall be a party, or
any entity succeeding to all or substantially all the corporate trust business
of such Issuer Trustee, shall be successor of such Issuer Trustee under the
Trust Agreement, provided such corporation shall be otherwise qualified and
eligible.

MERGER, CONSOLIDATION OR AMALGAMATION OF THE TRUST

         The Trust may not consolidate, amalgamate, merge with or into, or be
replaced by, or convey, transfer or lease its properties and assets
substantially as an entirety, to any corporation or other entity, except as
described below. The Trust may, with the consent of a majority of the
Administrative Trustees and without the consent of the holders of the Trust
Securities, the Property Trustee or the Delaware Trustee consolidate,
amalgamate, merge with or into, or be replaced by a trust organized as such
under the laws of any State of the United States; provided, that (i) if the
Trust is not the survivor, such successor entity either (x) expressly assumes
all of the obligations of the Trust under the Trust Securities or (y)
substitutes for the Preferred Securities other securities having substantially
the same terms as the Securities (the "Successor Securities"), so long as the
Successor Securities rank the same as the Preferred Securities rank with respect
to distributions, assets and payments, (ii) the Company expressly acknowledges a
trustee of such successor entity possessing the same powers and duties as the
Property Trustee as the holder of the Convertible Debentures, (iii) the
Preferred Securities or any Successor Securities are listed, or any Successor
Securities will be listed upon notification of issuance, on such national
securities exchange or with another organization on which the Preferred
Securities are then listed or quoted, (iv) such merger, consolidation,
amalgamation or replacement does not cause the Preferred Securities (including
any Successor Securities) to be downgraded by any nationally recognized
statistical rating organization, (v) such merger, consolidation, amalgamation or
replacement does not adversely affect the rights, preferences and privileges of
the holders of the Preferred Securities (including any Successor Securities) in
any material respect, (vi) such successor entity has a purpose substantially
identical to that of the Trust, (vii) the Company guarantees the obligations of
such successor entity under the Successor Securities to the same extent as
provided by the Guarantee and (viii) prior to such merger, consolidation,
amalgamation or replacement, the Company has received an opinion of a nationally
recognized independent counsel to the Trust reasonably acceptable to the
Property Trustee experienced in such matters to the effect that: (A) such
merger, consolidation, amalgamation or replacement will not adversely affect the
rights, preferences and privileges of the holders of the Trust Securities
(including any Successor Securities) in any material respect (other than with
respect to any dilution of the holders' interest in the new entity), (B)
following such merger, consolidation, amalgamation or replacement, neither the
Trust nor such successor entity will be required to register as an investment
company under the 1940 Act and (C) following such merger, consolidation,
amalgamation or replacement, the Trust (or such successor trust) will be treated
as a grantor trust for United States federal income tax purposes.
Notwithstanding the foregoing, the Trust shall not, except with the consent of
holders of 100% in liquidation amount of the Common Securities, consolidate,
amalgamate, merge with or into, or be replaced by any other entity or permit any
other entity to consolidate, amalgamate, merge with or into, or replace it, if
such consolidation, amalgamation, merger or replacement would cause the Trust or
the successor entity to be classified as other than a grantor trust for United
States federal income tax purposes.

DECLARATION EVENTS OF DEFAULT

         An event of default under the Indenture (an "Indenture Event of
Default") constitutes an event of default under the Trust Agreement with respect
to the Trust Securities (a "Declaration Event of Default"); provided, that
pursuant to the Trust Agreement, the holder of the Common Securities will be
deemed to have waived any Declaration Event of Default with respect to the
Common Securities until all Declaration Events of Default with respect to the
Preferred Securities have been cured, waived or otherwise eliminated. Until such
Declaration Events of Default with respect to the Preferred Securities have been
so cured, waived or otherwise eliminated, the Property Trustee will be deemed to
be acting solely on behalf of the holders of the Preferred Securities and only
the holders of the Preferred Securities will




                                       25

<PAGE>   26



have the right to direct the Property Trustee with respect to certain matters
under the Trust Agreement and, therefore, the Indenture.

         If the Property Trustee fails to enforce its rights under the
Convertible Debentures after a holder of Preferred Securities has made a written
request, such holder of record of Preferred Securities may directly institute a
legal proceeding against the Company to enforce the Property Trustee's rights
under the Convertible Debentures without first instituting any legal proceeding
against the Property Trustee or any other person or entity. Notwithstanding the
foregoing, if a Declaration Event of Default has occurred and is continuing and
such event is attributable to the failure of the Company to pay interest or
principal on the Convertible Debentures on the date such interest or principal
is otherwise payable (or in the case of redemption, the redemption date), then a
holder of Preferred Securities may directly institute a proceeding for
enforcement of payment to such holder of the principal of or interest on the
Convertible Debentures having a principal amount equal to the aggregate
liquidation amount of the Preferred Securities of such holder on or after the
respective due date specified in the Convertible Debentures. In connection with
such Direct Action, the Company will be subrogated to the rights of such holder
of Preferred Securities under the Trust Agreement to the extent of any payment
made by the Company to such holder of Preferred Securities in such Direct
Action. The holders of Preferred Securities will not be able to exercise
directly any other remedy available to the holders of the Convertible
Debentures.

         Within ten days after the occurrence of any Declaration Event of
Default actually known to the Property Trustee, the Property Trustee shall
transmit notice of such Declaration Event of Default to the holders of the
Preferred Securities, the Administrative Trustees and the Company, as Depositor,
unless such Declaration Event of Default shall have been cured or waived. Upon
the occurrence of a Declaration Event of Default, the Property Trustee as the
sole holder of the Convertible Debentures will have the right under the
Indenture to declare the principal of and interest on the Convertible Debentures
to be immediately due and payable. The Company and the Trust are each required
to file annually with the Property Trustee an officer's certificate as to its
compliance with all conditions and covenants under the Trust Agreement.

VOTING RIGHTS

         Except as described herein, under the Trust Act, the Trust Indenture
Act and under "Description of the Guarantee--Amendments and Assignment," and as
otherwise required by law and the Trust Agreement, the holders of the Preferred
Securities will have no voting rights.

         Subject to the requirement of the Property Trustee to obtain a tax
opinion in certain circumstances set forth in the last sentence of this
paragraph, the holders of a majority in liquidation amount of the Preferred
Securities have the right to direct the time, method and place of conducting any
proceeding for any remedy available to the Property Trustee, or direct the
exercise of any trust or power conferred upon the Property Trustee under the
Trust Agreement, including the right to direct the Property Trustee, as holder
of the Convertible Debentures, to (i) exercise the remedies available to it
under the Indenture as a holder of the Convertible Debentures, (ii) waive any
past Indenture Event of Default that is waivable under the Indenture, (iii)
exercise any right to rescind or annul a declaration that the principal of all
the Convertible Debentures shall be due and payable or (iv) consent to any
amendment, modification, or termination of the Indenture or the Convertible
Debentures where such consent shall be required; provided, however, that where a
consent or action under the Indenture would require the consent or act of the
holders of more than a majority of the aggregate principal amount of Convertible
Debentures affected thereby, only the holders of the percentage of the aggregate
stated liquidation amount of the Preferred Securities which is at least equal to
the percentage required under the Indenture may direct the Property Trustee to
give such consent or take such action. If the Property Trustee fails to enforce
its rights under the Convertible Debentures after a holder of record of
Preferred Securities has made a written request, such holder of record of
Preferred Securities may institute a legal proceeding directly against the
Company to enforce the Property Trustee's rights under the Convertible
Debentures without first instituting any legal proceeding against the Property
Trustee or any other person or entity. Notwithstanding the foregoing, if a
Declaration Event of Default has occurred and is continuing and such event is
attributable to the failure of the Company to pay interest or principal on the
Convertible Debentures on the date such interest or principal is otherwise
payable (or in the case of redemption on the redemption date), then a holder of
Preferred Securities may directly institute a proceeding for enforcement of
payment to such holder of the principal of or interest on the Convertible
Debentures having a principal amount equal to the aggregate liquidation amount
of the Preferred Securities of such holder on or after the respective due date
specified in the Convertible Debentures. The Property Trustee shall notify all
holders of the Preferred Securities of any notice of default received from the
Indenture Trustee with respect to the Convertible Debentures. Such notice shall
state that such Indenture Event of Default also constitutes a Declaration Event
of Default. The Property Trustee shall be under no obligation to take any of the
actions described in clause (i), (ii) or (iii) above unless the Property Trustee
has obtained an opinion of independent tax counsel to the effect that as a
result of such action, the Trust will not fail to be classified as a grantor
trust for United States federal income tax purposes and each holder will be
treated as owning an undivided beneficial interest in the Convertible
Debentures.

         In the event the consent of the Property Trustee, as the holder of the
Convertible Debentures, is required under the Indenture with respect to any
amendment, modification or termination of the Indenture, the Property Trustee
shall




                                       26

<PAGE>   27



request the direction of the holders of the Trust Securities with respect to
such amendment, modification or termination and shall vote with respect to such
amendment, modification or termination as directed by a majority in liquidation
amount of the Trust Securities voting together as a single class; provided,
however, that where a consent under the Indenture would require the consent of
the holders of more than a majority of the aggregate principal amount of the
Convertible Debentures, the Property Trustee may only give such consent at the
direction of the holders of at least the same proportion in aggregate stated
liquidation amount of the Trust Securities. The Property Trustee shall not take
any such action in accordance with the directions of the holders of the Trust
Securities unless the Property Trustee has obtained an opinion of tax counsel to
the effect that for the purposes of United States federal income tax the Trust
will not be classified as other than a grantor trust.

         A waiver of an Indenture Event of Default will constitute a waiver of
the corresponding Declaration Event of Default.

         Any required approval or direction of holders of Preferred Securities
may be given at a separate meeting of holders of Preferred Securities convened
for such purpose, at a meeting of all of the holders of Trust Securities or
pursuant to written consent. The Property Trustee will cause a notice of any
meeting at which holders of Preferred Securities are entitled to vote, or of any
matter upon which action by written consent of such holders is to be taken, to
be mailed to each holder of record of Preferred Securities. Each such notice
will include a statement setting forth the following information: (i) the date
of such meeting or the date by which such action is to be taken; (ii) a
description of any resolution proposed for adoption at such meeting on which
such holders are entitled to vote or of such matter upon which written consent
is sought; and (iii) instructions for the delivery of proxies or consents. No
vote or consent of the holders of Preferred Securities will be required for the
Trust to redeem and cancel Preferred Securities or distribute Convertible
Debentures in accordance with the Trust Agreement.

         Notwithstanding that holders of Preferred Securities are entitled to
vote or consent under any of the circumstances described above, any of the
Preferred Securities that are owned at such time by the Company or any entity
directly or indirectly controlling or controlled by, or under direct or indirect
common control with, the Company, shall not be entitled to vote or consent and
shall, for purposes of such vote or consent, be treated as if such Preferred
Securities were not outstanding.

         The procedures by which holders of Preferred Securities represented by
the Global Certificates may exercise their voting rights are described below.
See "--Book-Entry Only Issuance-The Depository Trust Company."

         Holders of the Preferred Securities will have no rights to appoint or
remove the Administrative Trustees, who may be appointed, removed or replaced
solely by the Company as the holder of all of the Common Securities.

MODIFICATION OF THE TRUST AGREEMENT

         The Trust Agreement may be modified and amended if approved by the
Administrative Trustees (and in certain circumstances the Property Trustee and
the Delaware Trustee); provided, that if any proposed amendment provides for, or
the Administrative Trustees otherwise propose to effect, (i) any action that
would adversely affect the powers, preferences or special rights of the Trust
Securities, whether by way of amendment to the Trust Agreement or otherwise or
(ii) the dissolution, winding-up or termination of the Trust other than pursuant
to the terms of the Trust Agreement, then the holders of the Trust Securities
voting together as a single class will be entitled to vote on such amendment or
proposal and such amendment or proposal shall not be effective except with the
approval of at least a majority in liquidation amount of the Trust Securities
affected thereby; provided, further, that if any amendment or proposal referred
to in clause (i) above would adversely affect only the Preferred Securities or
the Common Securities, then only the affected class will be entitled to vote on
such amendment or proposal and such amendment or proposal shall not be effective
except with the approval of a majority in liquidation amount of such class of
Securities.

         Notwithstanding the foregoing, no amendment or modification may be made
to the Trust Agreement if such amendment or modification would (i) cause the
Trust to be classified for purposes of United States federal income taxation as
other than a grantor trust, (ii) reduce or otherwise adversely affect the powers
of the Property Trustee or (iii) cause the Trust to be deemed an "investment
company" which is required to be registered under the 1940 Act.

REGISTRATION RIGHTS

         In connection with the Original Offering, the Company and the Trust
entered into a registration rights agreement dated March 18, 1998 with the
Initial Purchasers (the "Registration Rights Agreement") pursuant to which the
Company and the Trust would, at the Company's expense, for the benefit of the
holders of the Preferred Securities, the Guarantee, the Convertible Debentures
and the shares of Company Common Stock issuable upon conversion of the
Convertible Debentures (together, the "Registrable Securities"), (i) file with
the Commission, a registration statement (the "Shelf Registration Statement")
covering resales of the Registrable Securities, (ii) use their best efforts to
cause the Shelf Registration Statement to be declared effective under the
Securities Act within 150 days of and (iii) use their best efforts to keep
effective the Shelf Registration Statement until two years after the date it is
declared effective or such




                                       27

earlier date as all Registrable Securities shall have been disposed of or on
which all Registrable Securities held by persons that are not affiliates of the
Company or the Trust may be resold without registration pursuant to Rule 144(k)
under the Securities Act (the "Effectiveness Period"). The Company will provide
to each holder of Registrable Securities copies of this Prospectus which is a
part of the Shelf Registration Statement, notify each holder when the Shelf
Registration Statement has become effective and take certain other actions as
are required to permit unrestricted resales of the Registrable Securities. A
holder of Registrable Securities that sells such Registrable Securities pursuant
to the Shelf Registration Statement is required to be named as a selling
security holder in this Prospectus and to deliver this Prospectus to purchasers,
is subject to certain of the civil liability provisions under the Securities Act
in connection with such sales and is bound by the provisions of the Registration
Rights Agreement, including certain indemnification obligations.

         If (i) by May 17, 1998, the Shelf Registration Statement had not been
filed with the Commission, or (ii) by August 15, 1998, the Shelf Registration
Statement had not been declared effective (each, a "Registration Default"),
additional interest ("Liquidated Damages") will accrue on the Convertible
Debentures and, accordingly, additional distributions will accrue on the
Preferred Securities, in each case from and including the day following such
Registration Default. Liquidated Damages will be paid quarterly in arrears, with
the first quarterly payment due on the first interest or distribution payment
date, as applicable, following the date on which such Liquidated Damages begin
to accrue, and will accrue at a rate per annum equal to an additional
one-quarter of one percent (0.25%) of the principal amount or liquidation
amount, as applicable, to and including the 60th day following such Registration
Default and one-half of one percent (0.50%) thereof from and after the 61st day
following such Registration Default. The Company has the right to suspend the
Shelf Registration Statement under certain circumstances for up to 90
consecutive days. In the event that the Shelf Registration Statement ceases to
be effective during the Effectiveness Period for more than 90 consecutive days
or any 120 days, whether or not consecutive, during any 12-month period, then
the interest rate borne by the Convertible Debentures and the distribution rate
borne by the Preferred Securities will each increase by an additional one-half
of one percent (0.50%) per annum from such 91st or 121st day, as applicable,
until such time as the Shelf Registration Statement again becomes effective.
This Prospectus is a part of the Shelf Registration Statement filed in
accordance with the foregoing requirements.

         The summary herein of certain provisions of the Registration Rights
Agreement is subject to, and is qualified in its entirety by reference to, all
the provisions of the Registration Rights Agreement, a copy of which is
available upon request to the Company or the Initial Purchasers.

BOOK-ENTRY ONLY ISSUANCE-THE DEPOSITORY TRUST COMPANY

         The description of book-entry procedures in this Prospectus includes
summaries of certain rules and operating procedures of DTC that affect transfers
of interest in the global certificate or certificates issued in connection with
sales of Preferred Securities made pursuant to this Prospectus. The Preferred
Securities were issued only as fully registered securities registered in the
name of Cede & Co. (as nominee for DTC), in each case for credit to an account
of a direct or indirect participant in DTC as described below. One or more fully
registered global Preferred Security certificates (the "144A Global Securities")
was issued, representing in the aggregate, Preferred Securities sold in reliance
on Rule 144A and was deposited with DTC. One or more fully registered global
Preferred Security certificates (the "Regulation S Global Securities" and,
together with the 144A Global Securities, the "Global Securities") was issued,
representing in the aggregate, Preferred Securities sold in offshore
transactions in reliance on Regulation S and was deposited with DTC.

         The Regulation S Global Security initially was deposited with or on
behalf of DTC and was registered in the name of the Global Security holder for
credit to subscribers' accounts at Euroclear and Cedel Bank. Euroclear and Cedel
Bank are each Participants in DTC's system. Beneficial interests in the
Regulation S Global Security may be held only through Euroclear and Cedel until
the expiration of a 40-day restricted period, as defined under Regulation S (the
"Restricted Period"). After the expiration of the Restricted Period, investors
may hold beneficial interests in the Regulation S Global Security through
organizations other than Euroclear and Cedel Bank that are Participants in DTC's
system. Euroclear and Cedel Bank will hold interests in the Regulation S Global
Security on behalf of their Participants through customers' securities accounts
in their respective names on the books of their respective depositaries, which
are Morgan Guaranty Trust Company of New York, Brussels office, as operator of
Euroclear, and Citibank, N.A., as operator of Cedel Bank. In turn, each of
Euroclear and Cedel Bank will hold such interests in the Regulation S Global
Security in customers' securities accounts in its name on the books of DTC.

         The laws of some jurisdictions require that certain purchasers of
securities take physical delivery of securities in definitive form. Such laws
may impair the ability to transfer beneficial interests in the global Preferred
Securities as represented by a Global Security.

         DTC is a limited-purpose trust company organized under the New York
Banking Law, a "banking organization" within the meaning of the New York Banking
Law, a member of the Federal Reserve System, a "clearing corporation" within the
meaning of the New York Uniform Commercial Code, and a "clearing agency"
registered pursuant to the provisions of Section 17A of the Exchange Act. DTC
holds securities that its participants ("Participants")




                                       28

<PAGE>   29



deposit with DTC. DTC also facilitates the settlement among Participants of
securities transactions, such as transfers and pledges, in deposited securities
through electronic computerized book-entry changes in Participants' accounts,
thereby eliminating the need for physical movement of securities certificates.
Participants in DTC include securities brokers and dealers, banks, trust
companies, clearing corporations and certain other organizations. DTC is owned
by a number of its Participants and by the NYSE, the American Stock Exchange,
Inc., and the National Association of Securities Dealers, Inc. Access to the DTC
system is also available to others such as securities brokers and dealers, banks
and trust companies that clear through or maintain a custodial relationship with
a Participant, either directly or indirectly ("Indirect Participants"). The
rules applicable to DTC and its Participants are on file with the Commission.

         Purchases of Preferred Securities within the DTC system must be made by
or through Participants, which will receive a credit for the Preferred
Securities on DTC's records. The ownership interest of each actual purchaser of
Preferred Securities ("Beneficial Owner") is in turn to be recorded on the
Participants' and Indirect Participants' records. Beneficial Owners will not
receive written confirmation from DTC of their purchases, but Beneficial Owners
are expected to receive written confirmations providing details of the
transactions, as well as periodic statements of their holdings, from the
Participants or Indirect Participants through which the Beneficial Owners
purchased Preferred Securities. Transfers of ownership interests in the
Preferred Securities are to be accomplished by entries made on the books of
Participants and Indirect Participants acting on behalf of Beneficial Owners.
Beneficial Owners will not receive certificates representing their ownership
interests in Preferred Securities, except in the event that use of the
book-entry system for the Preferred Securities is discontinued.

         To facilitate subsequent transfers, all the Preferred Securities
deposited by Participants with DTC are registered in the name of DTC's nominee,
Cede & Co. The deposit of Preferred Securities with DTC and their registration
in the name of Cede & Co. effect no change in beneficial ownership. DTC has no
knowledge of the actual Beneficial Owners of the Preferred Securities; DTC's
records reflect only the identity of the Participants to whose accounts such
Preferred Securities are credited, which may or may not be the Beneficial
Owners. The Participants and Indirect Participants will remain responsible for
keeping account of their holdings on behalf of their customers.

         So long as DTC, or its nominee, is the registered owner or holder of a
Global Security, DTC or such nominee, as the case may be, will be considered the
sole owner or holder of the Preferred Securities represented thereby for all
purposes under the Trust Agreement and the Preferred Securities. No beneficial
owner of an interest in a Global Security will be able to transfer that interest
except in accordance with DTC's applicable procedures, in addition to those
provided for under the Trust Agreement.

         DTC has advised the Company that it will take any action permitted to
be taken by a holder of Preferred Securities (including the presentation of
Preferred Securities for exchange as described below) only at the direction of
one or more Participants to whose account the DTC interests in the Global
Securities are credited and only in respect of such portion of the aggregate
liquidation amount of Preferred Securities as to which such Participant or
Participants has or have given such direction. However, if there is an Event of
Default under the Preferred Securities, DTC will exchange the Global Securities
for Certificated Securities, which it will distribute to its Participants.

         Conveyance of notices and other communications by DTC to Participants,
by Participants to Indirect Participants, and by Participants and Indirect
Participants to Beneficial Owners will be governed by arrangements among them,
subject to any statutory or regulatory requirements as may be in effect from
time to time.

         Redemption notices in respect of the Preferred Securities held in
book-entry form will be sent to Cede & Co. If less than all of the Preferred
Securities are being redeemed, DTC will determine the amount of the interest of
each Participant to be redeemed in accordance with its procedures.

         Although voting with respect to the Preferred Securities is limited, in
those cases where a vote is required, neither DTC nor Cede & Co. will itself
consent or vote with respect to Preferred Securities. Under its usual
procedures, DTC would mail an Omnibus Proxy to the Trust as soon as possible
after the record date. The Omnibus Proxy assigns Cede & Co.'s consenting or
voting rights to those Participants to whose accounts the Preferred Securities
are credited on the record date (identified in a listing attached to the Omnibus
Proxy).

         Distributions on the Preferred Securities held in book-entry form will
be made to DTC in immediately available funds. DTC's practice is to credit
Participants' accounts on the relevant payment date in accordance with their
respective holdings shown on DTC's records unless DTC has reason to believe that
it will not receive payments on such payment date. Payments by Participants and
Indirect Participants to Beneficial Owners will be governed by standing
instructions and customary practices and will be the responsibility of such
Participants and Indirect Participants and not of DTC, the Trust or the Company,
subject to any statutory or regulatory requirements as may be in effect from
time to time. Payment of distributions to DTC is the responsibility of the
Trust, disbursement of such payments to Participants is the responsibility of
DTC, and disbursement of such payments to the Beneficial Owners is the
responsibility of Participants and Indirect Participants.





                                       29

<PAGE>   30



         Except as provided herein, a Beneficial Owner of an interest in a
Global Security will not be entitled to receive physical delivery of Preferred
Securities. Accordingly, each Beneficial Owner must rely on the procedures of
DTC to exercise any rights under the Preferred Securities.

         Although DTC has agreed to the foregoing procedures in order to
facilitate transfers of interests in the Global Securities among Participants of
DTC, DTC is under no obligation to perform or continue to perform such
procedures, and such procedures may be discontinued at any time. Neither the
Company, the Issuer nor the Trustee will have any responsibility for the
performance by DTC or its Participants or Indirect Participants under the rules
and procedures governing DTC. DTC may discontinue providing its services as
securities depository with respect to the Preferred Securities at any time by
giving notice to the Trust. Under such circumstances, in the event that a
successor securities depository is not obtained, Preferred Security certificates
are required to be printed and delivered. Additionally, the Trust (with the
consent of the Company) may decide to discontinue use of the system of
book-entry transfers through DTC (or a successor depository). In that event,
certificates for the Preferred Securities will be printed and delivered. In each
of the above circumstances, the Company will appoint a paying agent with respect
to the Preferred Securities.

         The information in this section concerning DTC and DTC's book-entry
system has been obtained from sources that the Company and the Trust believes to
be reliable, but the Trust takes no responsibility for the accuracy thereof.

ADDITIONAL INFORMATION CONCERNING EUROCLEAR AND CEDEL BANK

         Euroclear and Cedel Bank hold securities for participating
organizations and facilitate the clearance and settlement of securities
transactions between their respective participants through electronic book-entry
changes in accounts of such participants. Euroclear and Cedel Bank provide to
their participants, among other things, services for safekeeping,
administration, clearance and settlement of internationally traded securities
and securities lending and borrowing. Euroclear and Cedel Bank interface with
domestic securities markets. Euroclear and Cedel Bank participants are financial
institutions such as underwriters, securities brokers and dealers, banks, trust
companies and certain other organizations. Indirect access to Euroclear and
Cedel Bank is also available to others such as banks, brokers, dealers and trust
companies that clear through or maintain a custodian relationship with a
Euroclear or Cedel Bank participant, either directly or indirectly.

         When beneficial interests are to be transferred from the account of a
Participant (other than Morgan Guaranty Trust Company of New York and Citibank,
N.A., as depositaries for Euroclear and Cedel Bank, respectively) to the account
of a Euroclear participant or a Cedel Bank participant, the purchaser must send
instructions to Euroclear or Cedel Bank through a participant at least one
business day prior to settlement. Euroclear or Cedel Bank, as the case may be,
will instruct Morgan Guaranty Trust Company of New York or Citibank, N.A. to
receive the beneficial interests against payment. Payment will include interest
attributable to the beneficial interest from and including the last payment date
to and excluding the settlement date, on the basis of a calendar year consisting
of twelve 30-day calendar months. For transactions settling on the 31st day of
the month, payment will include interest accrued to and excluding the first day
of the following month. Payment will then be made by Morgan Guaranty Trust
Company of New York or Citibank, N.A., as the case may be, to the Participant's
account against delivery of the beneficial interests. After settlement has been
completed, the beneficial interests will be credited to the respective clearing
systems and by the clearing system, in accordance with its usual procedures, to
the Euroclear participants' or Cedel Bank participants' accounts. Credit for the
beneficial interests will appear on the next business day (European time) and
the cash debit will be back-valued to, and interest attributable to the
beneficial interests will accrue from, the value date (which would be the
preceding business day when settlement occurs in New York). If settlement is not
completed on the intended value date (i.e., the trade fails), the Euroclear or
Cedel Bank cash debit will instead be valued as of the actual settlement date.

         Euroclear participants and Cedel Bank participants will need to make
available to the respective clearing systems the funds necessary to process
same-day funds settlement. The most direct means of doing so is to preposition
funds for settlement, either from cash on hand or existing lines of credit, as
they would for any settlement occurring within Euroclear or Cedel Bank. Under
this approach, they may take on credit exposure to Euroclear or Cedel Bank until
the beneficial interests are credited to their accounts one day later. Finally,
day traders that use Euroclear or Cedel Bank and that purchase beneficial
interests from Participants for credit to Euroclear participants or Cedel Bank
participants should note that these trades would automatically fall on the sale
side unless affirmative action were taken to avoid these potential problems.

         Due to time zone differences in their favor, Euroclear participants and
Cedel Bank participants may employ their customary procedures for transactions
in which beneficial interests are to be transferred by the respective clearing
system, through Morgan Guaranty Trust Company of New York or Citibank, N.A., to
another Participant. The seller must send instructions to Euroclear or Cedel
Bank through a participant at least one business day prior to settlement. In
these cases, Euroclear or Cedel Bank will instruct Morgan Guaranty Trust Company
of New York or Citibank, N.A., as the case may be, to credit the beneficial
interests to the Participant's account against payment. Payment will include
interest attributable to the beneficial interest from and including the last
payment date to and excluding the settlement date on the basis of a calendar
year consisting of twelve 30-day calendar months. For transactions settling on
the 31st day of the month, payment will include interest accrued to and
excluding the first day of the following month. The




                                       30

<PAGE>   31



payment will then be reflected in the account of the Euroclear participant or
Cedel Bank participant the following business day, and receipt of the cash
proceeds in the Euroclear or Cedel Bank participant's account will be
back-valued to the value date (which would be the preceding business day, when
settlement occurs in New York). If the Euroclear participant or Cedel Bank
participant has a line of credit with its representative clearing system and
elects to draw on such line of credit in anticipation of receipt of the sale
proceeds in its account, the back-valuation may substantially reduce or offset
any overdraft charges incurred over that one-day period. If settlement is not
completed on the intended value date (i.e., if trade fails), receipt of the cash
proceeds in the Euroclear or Cedel Bank participant's account would instead be
valued as of the actual settlement date.

PAYMENT AND PAYING AGENCY

         Payments in respect of the Preferred Securities represented by the
Global Certificates shall be made to DTC, which shall credit the relevant
accounts at DTC on the applicable distribution dates or, in the case of
Certificated Securities, such payments shall be made by check mailed to the
address of the holder entitled thereto as such address shall appear on the
Trust's register. The Paying Agent shall initially be Chase Bank of Texas,
National Association. The Paying Agent shall be permitted to resign as Paying
Agent upon 30 days' written notice to the Issuer Trustees. In the event that
Chase Bank of Texas, National Association shall no longer be the Paying Agent,
the Trustee shall appoint a successor to act as Paying Agent (which shall be a
bank or trust company).

REGISTRAR, TRANSFER AGENT, PAYING AGENT AND CONVERSION AGENT

         The Property Trustee acts as Registrar, Transfer Agent, Paying Agent
and Conversion Agent for the Preferred Securities.

         Registration of transfers of Preferred Securities will be effected
without charge by or on behalf of the Trust, but upon payment (with the giving
of such indemnity as the Trust or the Company may require) in respect of any tax
or other government charges which may be imposed in relation to it.

         The Trust will not be required to register or cause to be registered
the transfer of Preferred Securities after such Preferred Securities have been
called for redemption.

INFORMATION CONCERNING THE PROPERTY TRUSTEE

         The Company and certain of its subsidiaries maintain deposit accounts
and conduct other banking transactions with the Property Trustee in the ordinary
course of their businesses. The Property Trustee, prior to the occurrence of a
default with respect to the Trust Securities, undertakes to perform only such
duties as are specifically set forth in the Trust Agreement and, after default,
shall exercise the same degree of care as a prudent individual would exercise in
the conduct of his or her own affairs. Subject to such provisions, the Property
Trustee is under no obligation to exercise any of the powers vested in it by the
Trust Agreement at the request of any holder of Preferred Securities, unless
offered reasonable indemnity by such holder against the costs, expenses and
liabilities which might be incurred thereby. The holders of Preferred Securities
will not be required to offer such indemnity in the event such holders, by
exercising their voting rights, direct the Property Trustee to take any action
following a Declaration Event of Default.

GOVERNING LAW

         The Trust Agreement and the Preferred Securities are governed by, and
construed in accordance with, the internal laws of the State of Delaware.

MISCELLANEOUS

         The Administrative Trustees are authorized and directed to conduct the
affairs of and to operate the Trust in such a way that the Trust will not be
deemed to be an "investment company" required to be registered under the 1940
Act or characterized as other than a grantor trust for United States federal
income tax purposes so that the Convertible Debentures will be treated as
indebtedness of the Company for United States federal income tax purposes. In
this connection, the Administrative Trustees are authorized to take any action,
not inconsistent with applicable law, the certificate of trust or the Trust
Agreement that the Administrative Trustees determine in their discretion to be
necessary or desirable for such purposes as long as such action does not
adversely affect the interests of the holders of the Preferred Securities.

         Holders of the Preferred Securities have no preemptive rights.

                          DESCRIPTION OF THE GUARANTEE

         Set forth below is a summary of information concerning the Guarantee
which was executed and delivered by the Company for the benefit of the holders
from time to time of the Preferred Securities. The summary does not purport to
be complete and is subject in all respects to the provisions of, and is
qualified in its entirety by reference to, the Guarantee. The Guarantee
incorporates by reference the terms of the Trust Indenture Act. It is expected
that at the time the Shelf Registration Statement becomes effective, the
Guarantee will be qualified under the Trust Indenture Act. Chase Bank of Texas,
National Association, as the Guarantee Trustee, will hold the Guarantee for the
benefit of the holders of the Preferred Securities.

GENERAL

         Pursuant to and to the extent set forth in the Guarantee, the Company
irrevocably and unconditionally agreed to pay in full to the holders of the
Preferred Securities (except to the extent paid by such Trust), as and when due,
regardless of any defense, right of set off or counterclaim which the Trust may
have or assert, the following payments (the "Guarantee Payments"), without
duplication: (i) any accrued and unpaid distributions that are required to be
paid on the Preferred Securities to the extent the Trust has funds available
therefor, (ii) the Redemption Price, with respect to any Preferred Securities
called for redemption by the Trust, to the extent the Trust has funds available
therefor and (iii) upon a voluntary or involuntary dissolution, winding-up or
termination of the Trust (other than in connection with the distribution of
Convertible Debentures to the holders of Preferred Securities or the redemption
of all the Preferred Securities), the lesser of (a) the aggregate of the
liquidation amount and all accrued and unpaid distributions on the Preferred
Securities to the date of payment to the extent the Trust has funds available
therefor and (b) the amount of assets of the Trust remaining available for
distribution to holders of Preferred Securities upon the liquidation of the
Trust. The holders of a majority in liquidation amount of the Preferred
Securities have the right to direct the time, method and place of conducting any
proceeding for any remedy available to the Guarantee Trustee or to direct the
exercise of any trust or power conferred upon the Guarantee Trustee under the
Guarantee. Any holder of Preferred Securities may directly institute a legal
proceeding against the Company to enforce the obligations of the Guarantor under
the Guarantee without first instituting a legal proceeding against the Trust,
the Guarantee Trustee or any other person or entity. If the Company were to
default on its obligation to pay amounts payable on the Convertible Debentures,
the Trust would lack available funds for the payment of distributions or amounts
payable on redemption of the Preferred Securities or otherwise, and in such
event holders of the Preferred Securities would not be able to rely upon the
Guarantee for payment of such amounts. Instead, a holder of the Preferred
Securities would be required to rely on the enforcement (1) by the Property
Trustee of its rights, as registered holder of the Convertible Debentures,
against the Company pursuant to the terms of the Convertible Debentures or (2)
by such holder of Preferred Securities of its right against the Company to
enforce payments on Convertible Debentures. See "Description of the Convertible
Debentures." The Trust Agreement provides that each holder of Preferred
Securities, by acceptance thereof, agrees to the provisions of the Guarantee,
including the subordination provisions thereof, and the Indenture.

         The Guarantee is a guarantee on a subordinated basis with respect to
the Preferred Securities from the time of issuance of such Preferred Securities
but does not apply to any payment of distributions or Redemption Price, or to
payments upon the dissolution, winding-up or termination of the Trust, except to
the extent the Trust shall have funds available therefor. If the Company does
not make interest payments on the Convertible Debentures, the Trust will not pay
distributions on the Preferred Securities and will not have funds available
therefor. See "Description of the Convertible Debentures." The Guarantee, when
taken together with the Company's obligations under the Convertible Debentures,
and the Indenture thereto and the Trust Agreement, including its obligations to
pay costs, expenses, debts and liabilities of the Trust (other than with respect
to the Trust Securities) provides a full and unconditional guarantee on a
subordinated basis by the Company of payments due on the Preferred Securities
issued by the Trust.

         The Company has also agreed separately to irrevocably and
unconditionally guarantee the obligations of the Trust with respect to the
Common Securities (the "Common Securities Guarantee") to the same extent as the
Guarantee, except that upon the occurrence and during the continuation of a
Declaration Event of Default, holders of Preferred Securities shall have
priority over holders of Common Securities with respect to distributions and
payments on liquidation, redemption or otherwise.

CERTAIN COVENANTS OF THE COMPANY

         In the Guarantee, the Company has covenanted that, so long as any
Preferred Securities remain outstanding, if (i) the Company has exercised its
option to defer interest payments on the Convertible Debentures by extending the
interest payment period and such extension shall be continuing, (ii) the Company
shall be in default with respect to its payment or other obligations under the
Guarantee or (iii) there shall have occurred and be continuing any event that,
with the giving of notice or the lapse of time or both, would constitute an
Indenture Event of Default, then the Company has agreed (a) not to declare or
pay dividends on, or make distributions with respect to, or redeem, purchase or
acquire, or make a liquidation payment with respect to, any of its capital stock
(other than (i) purchases or acquisitions of shares of Company Common Stock in
connection with the satisfaction by the Company of its obligations under any
employee benefit plans or the satisfaction by the Company of its obligations
pursuant to any contract or security requiring the




                                       32

<PAGE>   33



Company to purchase shares of Company Common Stock, (ii) as a result of a
reclassification of the Company's capital stock or the exchange or conversion of
one class or series of the Company's capital stock for another class or series
of the Company's capital stock or (iii) the purchase of fractional interests in
shares of the Company's capital stock pursuant to the conversion or exchange
provisions of such capital stock or the security being converted or exchanged
(or make any guarantee payments with respect to the foregoing)), (b) not to make
any payment of interest, principal or premium, if any, on or repay, repurchase
or redeem any debt securities of the Company that rank pari passu with or junior
to the Convertible Debentures (except by conversion into or exchange for shares
of its capital stock), and (c) not to make any guarantee payments with respect
to the foregoing (other than pursuant to the Guarantee).

         As part of the Guarantee, the Company agreed that it will honor all
obligations described therein relating to the conversion of the Preferred
Securities into Company Common Stock as described in "Description of the
Preferred Securities--Conversion Rights."

EVENTS OF DEFAULT

         An event of default under the Guarantee will occur upon the failure of
the Company to perform any of its payment or other obligations thereunder. The
holders of a majority in aggregate liquidation preference of the Preferred
Securities have the right to direct the time, method and place of conducting any
proceeding for any remedy available to the Guarantee Trustee in respect of the
Guarantee or to direct the exercise of any trust or power conferred upon the
Guarantee Trustee under the Guarantee.

         If the Guarantee Trustee fails to enforce the Guarantee, any holder of
the Preferred Securities may institute a legal proceeding directly against the
Company to enforce its rights under the Guarantee without first instituting a
legal proceeding against the Trust, the Guarantee Trustee or any other person or
entity. In addition, any record holder of Preferred Securities shall have the
right, which is absolute and unconditional, to proceed directly against the
Company to obtain Guarantee Payments, without first waiting to determine if the
Guarantee Trustee has enforced the Guarantee or instituting a legal proceeding
against the Trust, the Guarantee Trustee or any other person or entity. The
Company has waived any right or remedy to require that any action be brought
just against the Trust, or any other person or entity, before proceeding
directly against the Company.

         The Company, as guarantor, is required to file annually with the
Guarantee Trustee a certificate as to whether or not the company is in
compliance with all the conditions and covenants applicable to it under the
Guarantee.

AMENDMENTS AND ASSIGNMENT

         Except with respect to any changes that do not materially adversely
affect the rights of holders of Preferred Securities (in which case no vote will
be required), the Guarantee may be amended only with the prior approval of the
holders of at least a majority in liquidation amount of all the outstanding
Preferred Securities. The manner of obtaining any such approval of holders of
the Preferred Securities will be as set forth under "Description of the
Preferred Securities--Voting Rights." All guarantees and agreements contained in
the Guarantee shall bind the successors, assigns, receivers, trustees and
representatives of the Company and shall inure to the benefit of the holders of
the Preferred Securities then outstanding. Except in connection with any
permitted merger or consolidation of the Company with or into another entity or
any permitted sale, transfer or lease of the Company's assets to another entity
as described below under "Description of the Convertible Debentures," the
Company may not assign its rights or delegate its obligations under the
Guarantee without the prior approval of the holders of at least a majority of
the aggregate stated liquidation amount of the Preferred Securities then
outstanding.

TERMINATION OF THE GUARANTEE

         The Guarantee will terminate as to each holder of Preferred Securities
upon (i) full payment of the Redemption Price of all Preferred Securities, (ii)
distribution of the Convertible Debentures held by the Trust to the holders of
the Preferred Securities, (iii) liquidation of the Trust or (iv) the
distribution of Company Common Stock to such holder in respect of the conversion
of such holder's Preferred Securities into Company Common Stock and will
terminate completely upon full payment of the amounts payable in accordance with
the Declaration of the Trust. The Guarantee will continue to be effective or
will be reinstated, as the case may be, if at any time any holder of Preferred
Securities must restore payment of any sum paid under such Preferred Securities
or such Guarantee.

STATUS OF THE GUARANTEE; SUBORDINATION

         The Guarantee constitutes an unsecured obligation of the Company and
ranks (i) subordinate and junior to all other liabilities of the Company except
any liabilities that may be pari passu expressly by their terms, (ii) pari passu
with the most senior preferred stock issued from time to time by the Company and
with any guarantee now or hereafter entered into by the Company in respect of
any preferred or preference stock or preferred securities of any affiliate of
the Company and (iii) senior to the Company Common Stock. The terms of the
Preferred Securities provide that each




                                       33

<PAGE>   34



holder of Preferred Securities by acceptance thereof agrees to the subordination
provisions and other terms of the Guarantee.

         The Guarantee constitutes a guarantee of payment and not of collection
(that is, the guaranteed party may directly institute a legal proceeding against
the Company to enforce its rights under a Guarantee without instituting a legal
proceeding against any other person or entity).

INFORMATION CONCERNING THE GUARANTEE TRUSTEE

         The Guarantee Trustee, prior to the occurrence of a default with
respect to the Guarantee, undertakes to perform only such duties as are
specifically set forth in the Guarantee and, after default with respect to the
Guarantee, shall exercise the same degree of care as a prudent individual would
exercise in the conduct of his or her own affairs. Subject to such provision,
the Guarantee Trustee is under no obligation to exercise any of the powers
vested in it by the Guarantee at the request of any holder of Preferred
Securities unless it is offered reasonable indemnity against the costs, expenses
and liabilities that might be incurred thereby.

GOVERNING LAW

         The Guarantee is governed by, and construed in accordance with, the
laws of the State of New York.



                    DESCRIPTION OF THE CONVERTIBLE DEBENTURES

         Set forth below is a description of the specific terms of the
Convertible Debentures in which the Trust invested the proceeds from the
issuance and sale of the Trust Securities. The following description does not
purport to be complete and is subject to, and is qualified in its entirety by
reference to, the Indenture between the Company and Chase Bank of Texas,
National Association, as trustee (the "Indenture Trustee"), a copy of which may
be obtained from the Company upon request. Certain capitalized terms used herein
are defined in the Indenture.

         Under certain circumstances involving the dissolution of the Trust
following the occurrence of a Special Event, Convertible Debentures may be
distributed to the holders of the Trust Securities in liquidation of the Trust.
See "Description of the Preferred Securities--Special Event Redemption or
Distribution." If the Convertible Debentures are distributed to the holders of
Preferred Securities, the Company will use its best efforts to have the
Convertible Debentures listed on the NYSE or on such other national securities
exchange or similar organization on which the Preferred Securities are then
listed or quoted.

GENERAL

         The Convertible Debentures were issued as unsecured debt under the
Indenture. The Convertible Debentures were limited in aggregate principal amount
of $113,402,050, such amount being the sum of the aggregate stated liquidation
amount of the Preferred Securities and the Common Securities.

         The Convertible Debentures are not subject to a sinking fund provision.
The entire principal amount of the Convertible Debentures will become due and
payable, together with any accrued and unpaid interest thereon, including
Compounded Interest and Additional Interest (both as defined herein), if any, on
April 1, 2028.

         The Convertible Debentures, if distributed to holders of Preferred
Securities in liquidation of such holder's interest in the Trust, will initially
be issued in the same form as the Preferred Securities that such Convertible
Debentures replace. See "--Book-Entry and Settlement." Under certain limited
circumstances, Convertible Debentures may be issued in certificated form in
exchange for a Global Security. In the event that Convertible Debentures are
issued in certificated form, such Convertible Debentures will be in
denominations of $25 and integral multiples thereof and may be transferred or
exchanged at the offices described below.

         Payments on Convertible Debentures issued as a Global Security will be
made to DTC, a successor depositary or, in the event that no depositary is used,
to a Paying Agent for the Convertible Debentures. In the event Convertible
Debentures are issued in certificated form, principal and interest will be
payable, the transfer of the Convertible Debentures will be registrable and
Convertible Debentures will be exchangeable for Convertible Debentures of other
denominations of a like aggregate principal amount at the corporate trust office
of the Indenture Trustee in The City of New York; provided, that unless the
Convertible Debentures are held by the Trust or any successor permissible under
"Description of the Preferred Securities--Merger, Consolidation or Amalgamation
of the Trust," payment of interest may be made at the option of the Company by
check mailed to the address of the persons entitled thereto.





                                       34

<PAGE>   35



         There are no covenants or provisions in the Indenture that afford
holders of Convertible Debentures protection in the event of a highly leveraged
transaction or other similar transaction involving the Company that may
adversely affect such holders.

INTEREST

         Each Convertible Debenture bears interest at the rate of 5 1/4% per
annum from the original date of issuance, payable quarterly in arrears on
January 1, April 1, July 1 and October 1 (each, an "Interest Payment Date"),
commencing July 1, 1998, to the person in whose name such Convertible Debenture
is registered, subject to certain exceptions, at the close of business on the
Business Day next preceding such Interest Payment Date.

         The amount of interest payable for any period will be computed on the
basis of a 360-day year of twelve 30-day months. The amount of interest payable
for any period shorter than a full quarterly period for which interest is
computed will be computed on the basis of the actual number of days elapsed. In
the event that any date on which interest is payable on the Convertible
Debentures is not a Business Day, then payment of the interest payable on such
date will be made on the next succeeding day which is a Business Day (without
any interest or other payment in respect of any such delay), except that, if
such Business Day is in the next succeeding calendar year, such payment shall be
made on the immediately preceding Business Day, in each case with the same force
and effect as if made on such date.

OPTION TO EXTEND INTEREST PAYMENT PERIODS

         So long as no Event of Default under the Indenture has occurred and is
continuing, the Company shall have the right at any time during the term of the
Convertible Debentures to defer interest payments from time to time by extending
the interest payment period for successive periods not exceeding 20 consecutive
quarters for each such period (each an Extension Period); provided, no Extension
Period may extend beyond the maturity date of the Convertible Debentures. At the
end of each Extension Period, the Company shall pay all interest then accrued
and unpaid (including Additional Interest and Liquidated Damages, if any)
together with interest thereon compounded quarterly at the rate specified for
the Convertible Debentures to the extent permitted by applicable law
("Compounded Interest"); provided, that during any Extension Period, the Company
has agreed, among other things, (a) not to declare or pay dividends on, or make
distributions with respect to, or redeem, purchase or acquire, or make a
liquidation payment with respect to, any of its capital stock (other than (i)
purchases or acquisitions of shares of Company Common Stock in connection with
the satisfaction by the Company of its obligations under any employee benefit
plans or the satisfaction by the Company of its obligations pursuant to any
contract or security requiring the Company to purchase shares of Company Common
Stock, (ii) as a result of a reclassification of the Company's capital stock or
the exchange or conversion of one class or series of the Company's capital stock
for another class or series of the Company's capital stock or (iii) the purchase
of fractional interests in shares of the Company's capital stock pursuant to the
conversion or exchange provisions of such capital stock or the security being
converted or exchanged (or make any guarantee payments with respect to the
foregoing)), (b) not to make any payment of interest, principal or premium, if
any, on or repay, repurchase or redeem, any debt securities issued by the
Company that rank pari passu with or junior to the Convertible Debentures
(except by conversion into or exchange for shares of its capital stock) and (c)
shall not make any guarantee payments with respect to the foregoing. Prior to
the termination of any such Extension Period, the Company may further extend
such Extension Period; provided, that such Extension Period together with all
previous and further extensions thereof may not exceed 20 consecutive quarters
and may not extend beyond the maturity of the Convertible Debentures. Upon the
termination of any Extension Period and the payment of all amounts then due, the
Company may commence a new Extension Period, subject to the above requirements.
No interest during an Extension Period, except at the end thereof, shall be due
and payable. The Company has no current intention of exercising its right to
defer payments of interest by extending the interest payment period on the
Convertible Debentures. If the Property Trustee shall be the sole holder of the
Convertible Debentures at the time the Company selects an Extension Period, the
Company shall give the Administrative Trustees and the Property Trustee notice
of its selection of such Extension Period at least one Business Day prior to the
earlier of (i) the date the distributions on the Preferred Securities are
payable or (ii) the date the Trust is required to give notice to the NYSE (or
any applicable self-regulatory organization) or to holders of the Preferred
Securities of the record date or the date such distribution is payable, but in
any event not less than ten Business Days prior to such record date. The Company
shall cause the Trust to give notice of the Company's selection of such
Extension Period to the holders of the Preferred Securities. If the Property
Trustee shall not be the sole holder of the Convertible Debentures at the time
the Company selects an Extension Period, the Company shall give the holders of
the Convertible Debentures notice of its selection of such Extension Period at
least ten Business Days prior to the earlier of (i) the Interest Payment Date or
(ii) the date the Company is required to give notice to the NYSE (or any
applicable self-regulatory organization) or to holders of the Convertible
Debentures on the record or payment date of such related interest payment, but
in any event not less than two Business Days prior to such record date.

ADDITIONAL INTEREST

         If the Trust would be required to pay any taxes, duties, assessments or
governmental charges of whatever nature (other than withholding taxes) imposed
by the United States, or any other taxing authority, then, in any such case, the
Company will pay as additional interest ("Additional Interest") such amounts as
shall be required so that the net amounts




                                       35

<PAGE>   36



received and retained by the Trust after paying any such taxes, duties,
assessments or governmental charges will be not less than the amounts the Trust
would have received had no such taxes, duties, assessments or governmental
charges been imposed.

CONVERSION OF THE CONVERTIBLE DEBENTURES

         The Convertible Debentures are convertible into Company Common Stock at
the option of the holders of the Convertible Debentures at any time prior to
5:00 p.m. (New York City time) the Business Day immediately preceding the date
of repayment of such Convertible Debentures, whether at maturity or upon
redemption (either at the option of the Company or pursuant to a Tax Event), at
the initial conversion price set forth on the cover page of this Prospectus
subject to the conversion price adjustments described under "Description of the
Preferred Securities--Conversion Rights." The Trust will covenant not to convert
Convertible Debentures held by it except pursuant to a notice of conversion
delivered to the Conversion Agent by a holder of Preferred Securities. Upon
surrender of a Preferred Security to the Conversion Agent for conversion, the
Trust will distribute $25 principal amount of the Convertible Debentures to the
Conversion Agent on behalf of the holder of the Preferred Securities so
converted, whereupon the Conversion Agent will convert such Convertible
Debentures to Company Common Stock on behalf of such holder. The Company's
delivery to the holders of the Convertible Debentures (through the Conversion
Agent) of the fixed number of shares of Company Common Stock into which the
Convertible Debentures are convertible (together with the cash payment, if any,
in lieu of fractional shares) will be deemed to satisfy the Company's obligation
to pay the principal amount of the Convertible Debentures so converted, and the
accrued and unpaid interest thereon attributable to the period from the last
date to which interest has been paid or duly provided for; provided, however,
that if any Convertible Debenture is converted after a record date for payment
of interest, the interest payable on the related interest payment date with
respect to such Convertible Debenture shall be paid to the Trust (which will
distribute such interest to the converting holder) or other holder of
Convertible Debentures, as the case may be, despite such conversion; provided,
further that if any Convertible Debentures delivered for conversion during an
Extension Period of redemption thereof from the Property Trustee to the holders
of the Preferred Securities, the Company shall be required to pay to the Trust
all accrued and unpaid interest, if any, on such Convertible Debentures through
the date of conversion which amount shall be simultaneously distributed to the
holders of the Preferred Securities in respect of which such Convertible
Debentures were delivered. See "--Optional Redemption," "Description of the
Preferred Securities--Conversion Rights" and "--Redemption."

MANDATORY REDEMPTION

         Upon repayment at maturity or as a result of acceleration upon the
occurrence of an Indenture Event of Default, the Company will redeem the
Convertible Debentures, in whole but not in part, at a redemption price equal to
100% of the principal amount thereof, together with any accrued and unpaid
interest thereon. Any payment pursuant to this provision shall be made prior to
12:00 noon, New York City time, on the date of such repayment or acceleration or
at such other time on such earlier date as the parties thereto shall agree. The
Convertible Debentures are not entitled to the benefit of any sinking fund or,
except as set forth above or as a result of acceleration, any other provision
for mandatory prepayment.

OPTIONAL REDEMPTION

         The Company shall have the right to redeem the Convertible Debentures,
in whole or in part, at any time or from time to time after April 3, 2001, upon
not less than 30 nor more than 60 days' notice, at the optional redemption
prices (expressed as a percentage of the principal amount of Convertible
Debentures to be redeemed) shown in the table below, plus any accrued and unpaid
interest, including Additional Interest, Compounded Interest and Liquidated
Damages, if any, to the redemption date, if redeemed during the 12-month period
beginning April 3:

</TABLE>

If the Company has deferred interest payments, all unpaid interest must be paid
in cash prior to redemption.

         If a partial redemption of the Preferred Securities resulting from a
partial redemption of the Convertible Debentures would result in the delisting
of the Preferred Securities, the Company may only redeem Convertible Debentures
in whole.

<PAGE>   37



REDEMPTION PROCEDURES

         Notices of any redemption of the Convertible Debentures and the
procedures for such redemption shall be as provided with respect to the
Preferred Securities under "Description of the Preferred Securities--Redemption
Procedures." Notice of any redemption will be mailed at least 30 days but not
more than 60 days before the redemption date to each holder of Convertible
Debentures to be redeemed at its registered address. Unless the Company defaults
in payment of the redemption price, on and after the redemption date interest
shall cease to accrue on such Convertible Debentures or portions thereof called
for redemption.

DISTRIBUTION OF CONVERTIBLE DEBENTURES

         At any time, the Company has the right to dissolve the Trust and, after
satisfaction of the liabilities of creditors of the Trust as provided by
applicable law, cause the Convertible Debentures to be distributed to the
holders of the Preferred Securities in dissolution of the Trust. If distributed
to holders of Preferred Securities in liquidation, the Convertible Debentures
will initially be issued in the form of one or more global securities and DTC,
or any successor depositary for the Preferred Securities, will act as depositary
for the Convertible Debentures. It is anticipated that the depositary
arrangements for the Convertible Debentures would be substantially identical to
those in effect for the Preferred Securities. There can be no assurance as to
the market price of any Convertible Debentures that may be distributed to the
holders of Preferred Securities. For a description of DTC and the terms of the
depositary matters, see "--Book-Entry and Settlement."

SUBORDINATION

         The Indenture provides that the Convertible Debentures are subordinate
and junior in right of payment to all existing and future Senior Indebtedness of
the Company. No payment of principal of (including redemption payments, if any),
premium, if any, or interest on, the Convertible Debentures may be made if (i)
any Senior Indebtedness of the Company is not paid when due and any applicable
grace period with respect to such default has ended and such default has not
been cured or waived, or ceased to exist or (ii) the maturity of any Senior
Indebtedness of the Company has been accelerated because of a default. At
December 31, 1997, Senior Indebtedness of the Company was approximately $101.9
million. Upon any distribution of assets of the Company to creditors upon any
dissolution, winding up, liquidation or reorganization, whether voluntary or
involuntary or in bankruptcy, insolvency, receivership or other proceedings, all
principal of, and premium, if any, and interest due or to become due on, all
Senior Indebtedness of the Company must be paid in full before the holders of
the Convertible Debentures are entitled to receive or retain any payment. Upon
satisfaction of all claims related to all Senior Indebtedness of the Company
then outstanding, the rights of the holders of the Preferred Securities will be
subrogated to the rights of the holders of Senior Indebtedness of the Company to
receive payments or distributions applicable to Senior Indebtedness until all
amounts owing on the Convertible Debentures are paid in full.

         The term "Senior Indebtedness" shall mean in respect of the Company:
(i) the principal, premium, if any, and interest in respect of (A) indebtedness
of such obligor for money borrowed and (B) indebtedness evidenced by securities,
debentures, bonds or other similar instruments issued by such obligor, (ii) all
capital lease obligations of such obligor, (iii) all obligations of such obligor
issued or assumed as the deferred purchase price of property, all conditional
sale obligations of such obligor and all obligations of such obligor under any
title retention agreement (but excluding trade accounts payable arising in the
ordinary course of business), (iv) all obligations of such obligor for the
reimbursement of any letter of credit, banker's acceptance, security purchase
facility or similar credit transaction, (v) all obligations of the type referred
to in clauses (i) through (iv) above of other persons for the payment of which
such obligor is responsible or liable as obligor, guarantor or otherwise, and
(vi) all obligations of the type referred to in clauses (i) through (v) above of
other persons secured by any lien on any property or asset of such obligor
(whether or not such obligation is assumed by such obligor), except for (1) any
such indebtedness that is by its terms subordinated to or pari passu with the
Convertible Debentures and (2) any indebtedness between or among such obligor or
its affiliates, including all other debt securities and guarantees in respect of
those debt securities issued to any other trust, or trustee of such trust,
partnership or other entity affiliated with the Company that is, directly or
indirectly, a financing vehicle of the Company (a "Financing Entity") in
connection with the issuance by such Financing Entity of preferred securities or
other securities that rank pari passu with, or junior to, the Preferred
Securities. Such Senior Indebtedness shall continue to be Senior Indebtedness
and entitled to the benefits of the subordination provisions irrespective of any
amendment, modification or waiver of any term of such Senior Indebtedness.

         The Indenture does not limit the aggregate amount of Senior
Indebtedness that may be issued by the Company. See "Capitalization."

CERTAIN COVENANTS

         In the Indenture, the Company has covenanted that, so long as any
Convertible Debentures are outstanding, if (i) there shall have occurred and be
continuing any event that with the giving of notice or the lapse of time or
both, would constitute an Indenture Event of Default, (ii) the Company shall be
in default with respect to its payment of any




                                       37

<PAGE>   38



obligations under the Guarantee, or (iii) the Company has exercised its option
to defer interest payments on the Convertible Debentures by extending the
interest payment period and such period, or any extension thereof, shall be
continuing, then the Company has agreed (a) not to declare or pay dividends on,
make distributions with respect to, or redeem, purchase or acquire, or make a
liquidation payment with respect to, any of its capital stock (other than (i)
purchases or acquisitions of shares of Company Common Stock in connection with
the satisfaction by the Company of its obligations under any employee benefit
plans or the satisfaction by the Company of its obligations pursuant to any
contract or security requiring the Company to purchase shares of Company Common
Stock, (ii) as a result of a reclassification of the Company's capital stock or
the exchange or conversion of one class or series of the Company's capital stock
for another class or series of the Company's capital stock or (iii) the purchase
of fractional interests in shares of the Company's capital stock pursuant to the
conversion or exchange provisions of such capital stock or the security being
converted or exchanged (or make any guarantee payments with respect to the
foregoing)), (b) not to make any payment of interest, principal or premium, if
any, on or repay, repurchase or redeem any debt securities issued by the Company
that rank pari passu with or junior to the Convertible Debentures (except by
conversion into or exchange for shares of its capital stock), and (c) not to
make any guarantee payments with respect to the foregoing (other than pursuant
to the Guarantee).

         The Company has covenanted (i) to directly or indirectly maintain 100%
ownership of the Common Securities of the Trust; provided, however, that any
permitted successor of the Company under the Indenture may succeed to the
Company's ownership of such Common Securities and (ii) to use its reasonable
efforts to cause the Trust (x) to remain a statutory business trust, except in
connection with the distribution of Convertible Debentures to the holders of
Trust Securities in liquidation of the Trust, the redemption of all of the Trust
Securities of the Trust, or certain mergers, consolidations or amalgamations,
each as permitted by the Trust Agreement, and (y) to otherwise continue to be
classified as a grantor trust for United States federal income tax purposes.

CONSOLIDATION, MERGER AND SALE OF ASSETS

         The Indenture provides that the Company will not consolidate with or
merge into any other corporation or convey, transfer or lease its assets
substantially as an entirety unless (a) if the Company is not the survivor, the
successor is a corporation organized in the United States and expressly assumes
the due and punctual payment of the principal of (and premium, if any) and
interest on all Convertible Debentures issued thereunder and the performance of
every other covenant of the Indenture on the part of the Company and (b)
immediately thereafter no event of default under the Indenture and no event
which, after notice or lapse of time, or both, would become an event of default
under the Indenture, shall have happened and be continuing. Upon any such
consolidation, merger, conveyance or transfer, the successor corporation shall
succeed to and be substituted for the Company under the Indenture and thereafter
the predecessor corporation shall be relieved of all obligations and covenants
under the Indenture and the Convertible Debentures.

BOOK-ENTRY AND SETTLEMENT

         If distributed to holders of the Preferred Securities in connection
with the involuntary or voluntary dissolution, winding-up or liquidation of the
Trust as a result of the occurrence of a Special Event, the Convertible
Debentures will be issued in the same form as the Preferred Securities which
such Convertible Debentures replace. Any Global Security will be replaced by one
or more global certificates (each a "Global Security") registered in the name of
the depositary or its nominee. Except under the limited circumstances described
below, the Convertible Debentures represented by the Global Security will not be
exchangeable for, and will not otherwise be issuable as, Convertible Debentures
in definitive form. The Global Securities described above may not be transferred
except 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 to a
successor depositary or its nominee.

         The laws of some jurisdictions require that certain purchasers of
securities take physical delivery of such securities in definitive form. Such
laws may impair the ability to transfer beneficial interests in such a Global
Security.

         Except as provided below, owners of beneficial interests in such a
Global Security are not entitled to receive physical delivery of Convertible
Debentures in definitive form and are not considered the holders thereof for any
purpose under the Indenture, and no Global Security representing Convertible
Debentures shall be exchangeable, except for another Global Security of like
denomination and tenor to be registered in the name of the depositary or its
nominee or to a successor depositary or its nominee. Accordingly, each
Beneficial Owner must rely on the procedures of DTC or if such person is not a
Participant, on the procedures of the Participant through which such person owns
its interest to exercise any rights of a holder under the Indenture.

         For a description of DTC and the specific terms of the depositary
arrangements, see "Description of the Preferred Securities--Book-Entry Only
Issuance-The Depository Trust Company." As of the date of this Prospectus, the
description herein of DTC's book-entry system and DTC's practices as they relate
to purchases, transfers, notices and payments with respect to the Convertible
Preferred Securities apply in all material respects to any debt obligations
represented by one or more Global Securities held by DTC. The Company may
appoint a successor to DTC or any




                                       38

<PAGE>   39



successor depositary in the event DTC or such successor depositary is unable or
unwilling to continue as a depositary for the Global Securities.

         None of the Company, the Trust, the Indenture Trustee, any paying agent
and any other agent of the Company or the Indenture Trustee has any
responsibility or liability for any aspect of the records relating to or
payments made on account of beneficial ownership interests in a Global Security
for such Convertible Debentures or for maintaining, supervising or reviewing any
records relating to such beneficial ownership interests.

         A Global Security shall be exchangeable for Convertible Debentures
registered in the names of persons other than the depositary or its nominee only
if (i) the depositary notifies the Company that it is unwilling or unable to
continue as a depositary for such Global Security and no successor depositary
shall have been appointed, (ii) the depositary, at any time, ceases to be a
clearing agency registered under the Exchange Act at which time the depositary
is required to be so registered to act as such depositary and no successor
depositary shall have been appointed, (iii) the Company, in its sole discretion,
determines that such Global Security shall be so exchangeable or (iv) there
shall have occurred an Event of Default with respect to such Convertible
Debentures. Any Global Security that is exchangeable pursuant to the preceding
sentence shall be exchangeable for Convertible Debentures registered in such
names as the depositary shall direct. It is expected that such instructions will
be based upon directions received by the depositary from its Participants with
respect to ownership of beneficial interests in such Global Security.

PAYMENT AND PAYING AGENTS

         Payments on Convertible Debentures represented by a Global Security
will be made to DTC, as the depositary for the Convertible Debentures. In the
event Convertible Debentures are issued in definitive form, principal of and
premium, if any, and any interest on Convertible Debentures will be payable, the
transfer of the Convertible Debentures will be registrable, and the Convertible
Debentures will be exchangeable for Convertible Debentures of other
denominations of a like aggregate principal amount at the corporate office of
the Indenture Trustee in the City of New York or at the office of such Paying
Agent or Paying Agents as the Company may designate, except that at the option
of the Company payment of any interest may be made (i) by check mailed to the
address of the Person entitled thereto as such address shall appear in the
Securities Register or (ii) by wire transfer to an account maintained by the
Person entitled thereto as specified in the Securities Register, provided that
proper transfer instructions have been received by the Regular Record Date.
Payment of any interest on Convertible Debentures will be made to the Person in
whose name such Convertible Debentures are registered at the close of business
on the Regular Record Date for such interest, except in the case of defaulted
interest. The Regular Record Date for the interest payable on any Interest
Payment Date shall be the fifteenth day (whether or not a Business Day) next
preceding such Interest Payment Date. The Company may at any time designate
additional Paying Agents or rescind the designation of any Paying Agent.

         Any monies deposited with the Indenture 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 Convertible Debentures and remaining
unclaimed for two years after such principal and premium, if any, or interest
has become due and payable shall, at the request of the Company, be repaid to
the Company and the holder of such Convertible Debentures shall thereafter look,
as a general unsecured creditor, only to the Company for payment thereof.

EVENTS OF DEFAULT

         The Indenture provides that any one or more of the following described
events, which has occurred and is continuing, constitutes an "Event of Default"
with respect to the Convertible Debentures: (i) failure for 30 days to pay
interest on the Convertible Debentures, including any Additional Interest,
Compounded Interest and Liquidated Damages, if any, in respect thereof, when due
provided that a valid extension of an interest payment period will not
constitute a default in the payment of interest (including any Additional
Interest, Compounded Interest or Liquidated Damages, if any) for this purpose;
or (ii) failure to pay principal of or premium, if any, on the Convertible
Debentures when due whether at maturity, upon redemption, by declaration or
otherwise; or (iii) failure by the Company to deliver shares of Company Common
Stock upon an election by a holder of Preferred Securities to convert such
Preferred Securities; or (iv) failure to observe or perform any other covenant
contained in the Indenture for 90 days after notice to the Company by the
Trustee or by the holders of not less than 25% in aggregate outstanding
principal amount of the Convertible Debentures; (v) the dissolution, winding up
or termination of the Trust, except in connection with the distribution of
Convertible Debentures to the holders of Preferred Securities in liquidation of
the Trust upon the redemption of all outstanding Preferred Securities and in
connection with certain mergers, consolidations or amalgamations permitted by
the Declaration; or (vi) certain events in bankruptcy, insolvency or
reorganization of the Company.

         The Indenture Trustee or the holders of not less than 25% in aggregate
outstanding principal amount of the Convertible Debentures may declare the
principal of and interest on the Convertible Debentures due and payable
immediately on the occurrence of an Event of Default; provided, however, that,
after such acceleration, but before a judgment or decree based on acceleration,
the holders of a majority in aggregate principal amount of outstanding
Convertible Debentures may, under certain circumstances, rescind and annul such
acceleration if all Events of Default,




                                       39

<PAGE>   40



other than the nonpayment of accelerated principal, have been cured or waived as
provided in the Indenture. For information as to waiver of defaults, see
"--Modifications and Amendments of the Indenture."

         Notwithstanding the foregoing, if an Indenture Event of Default has
occurred and is continuing and such event is attributable to the failure of the
Company to pay interest or principal on the Convertible Debentures on the date
such interest or principal is otherwise payable, the Company acknowledges that,
in such event, a holder of Preferred Securities may institute a Direct Action
for payment on or after the respective due date specified in the Convertible
Debentures. The Company may not amend the Indenture to remove the foregoing
right to bring a Direct Action without the prior written consent of all the
holders of Preferred Securities. Notwithstanding any payment made to such holder
of Preferred Securities by the Company in connection with a Direct Action, the
Company shall remain obligated to pay the principal of or interest on the
Convertible Debentures held by the Trust or the Property Trustee and the Company
shall be subrogated to the rights of the holder of such Preferred Securities
with respect to payments on the Preferred Securities to the extent of any
payments made by the Company to such holder in any Direct Action. The holders of
Preferred Securities will not be able to exercise directly any other remedy
available to the holders of the Convertible Debentures.

         The Holders of not less than a majority in principal amount of the
outstanding Convertible Debentures may on behalf of the holders of all the
Convertible Debentures waive any past defaults except (a) a default in payment
of the principal of (or premium, if any) or interest, if any, on any Convertible
Debentures and (b) a default in respect of a covenant or provision of the
Indenture which cannot be amended or modified without the consent of the holder
of each Convertible Debenture; provided, however, that if the Convertible
Debentures are held by the Trust or a trustee of such Trust, such waiver or
modification to such waiver shall not be effective until the holders of a
majority in liquidation amount of Trust Securities shall have consented to such
waiver or modification to such waiver; provided, further, that if the consent of
the holder of each outstanding Convertible Debenture is required, such waiver
shall not be effective until each holder of the Trust Securities shall have
consented to such waiver.

         A default under any other indebtedness of the Company or the Trust
would not constitute an Event of Default under the Convertible Debentures.

         Subject to the provisions of the Indenture relating to the duties of
the Indenture Trustee in case an Event of Default shall occur and be continuing,
the Indenture Trustee is under no obligation to exercise any of its rights or
powers under the Indenture at the request or direction of any holders of
Convertible Debentures, unless such holders shall have offered to the Indenture
Trustee reasonable indemnity. Subject to such provisions for the indemnification
of the Indenture Trustee, the holders of a majority in aggregate principal
amount of the Convertible Debentures then outstanding will have the right to
direct the time, method and place of conducting any proceeding for any remedy
available to the Indenture Trustee, or exercising any trust or power conferred
on the Indenture Trustee with respect to such series.

         No holder of any Convertible Debenture has any right to institute any
proceeding with respect to the Indenture or for any remedy thereunder, unless
(i) such holder shall have previously given to the Indenture Trustee written
notice of a continuing Event of Default, (ii) if the Trust is not the sole
holder of Convertible Debentures, the holders of at least 25% in aggregate
principal amount of the Convertible Debentures then outstanding shall also have
made written request, (iii) such holder has offered reasonable indemnity to the
Indenture Trustee to institute such proceeding as Indenture Trustee, (iv) the
Indenture Trustee shall have failed to institute such proceeding within 60 days
of such notice, and (v) the Indenture Trustee shall not have received from the
holders of a majority in aggregate principal amount of the outstanding
Convertible Debentures a direction inconsistent with such request. However, such
limitations do not apply to a suit instituted by a holder of a Convertible
Debenture for enforcement of payment of the principal of or interest on such
Convertible Debenture on or after the respective due dates expressed in such
Convertible Debenture.

         The Company is required to file annually with the Indenture Trustee and
the Property Trustee a certificate as to whether or not the Company is in
compliance with all the conditions and covenants under the Indenture.

MODIFICATIONS AND AMENDMENTS OF THE INDENTURE

         The Indenture contains provisions permitting the Company and the
Indenture Trustee, with the consent of the holders of not less than a majority
in aggregate principal amount of the outstanding Convertible Debentures, to
modify the Indenture or the rights of the holders of Convertible Debentures;
provided, however, that no such modification may, without the consent of the
holder of each outstanding Convertible Debenture affected thereby, (i) extend
the stated maturity of the Convertible Debentures or reduce the principal amount
thereof, or reduce the rate or extend the time of payment of interest thereon,
or reduce any premium payable upon the redemption thereof, or adversely affect
the right to convert Convertible Debentures or the subordination provisions of
the Indenture, or (ii) reduce the percentage in aggregate principal amount of
outstanding Convertible Debentures, the holders of which are required to consent
to any such supplemental indenture.




                                       40

<PAGE>   41



         In addition, the Company and the Indenture Trustee may execute, without
the consent of any holder of Convertible Debentures, any supplemental indenture
to cure any ambiguities, comply with the Trust Indenture Act and for certain
other customary purposes.

GOVERNING LAW

         The Indenture and the Convertible Debentures are governed by, and
construed in accordance with, the laws of the State of New York.

INFORMATION CONCERNING THE INDENTURE TRUSTEE

         The Indenture Trustee, prior to default, undertakes to perform only
such duties as are specifically set forth in the Indenture and, after default,
shall exercise the same degree of care as a prudent individual would exercise in
the conduct of his or her own affairs. Subject to such provision, the Indenture
Trustee is under no obligation to exercise any of the powers vested in it by the
Indenture at the request of any holder of Convertible Debentures, unless offered
reasonable indemnity by such holder against the costs, expenses and liabilities
which might be incurred thereby. The Indenture Trustee is not required to expend
or risk its own funds or otherwise incur personal financial liability in the
performance of its duties if the Indenture Trustee reasonably believes that
repayment or adequate indemnity is not reasonably assured to it.



             EFFECT OF OBLIGATIONS UNDER THE CONVERTIBLE DEBENTURES
                                AND THE GUARANTEE

         As set forth in the Trust Agreement, the sole purpose of the Trust is
to issue the Trust Securities evidencing undivided beneficial interests in the
assets of the Trust, and to invest the proceeds from such issuance and sale in
the Convertible Debentures.

         As long as payments of interest and other payments are made when due on
the Convertible Debentures, such payments will be sufficient to cover
distributions and payments due on the Trust Securities because of the following
factors: (i) the aggregate principal amount of Convertible Debentures will be
equal to the sum of the aggregate stated liquidation amount of the Trust
Securities; (ii) the interest rate and the interest and other payment dates on
the Convertible Debentures will match the distribution rate and distribution and
other payment dates for the Preferred Securities; (iii) pursuant to the
Indenture, the Company shall pay, and the Trust shall not be obligated to pay,
directly or indirectly, all costs, expenses, debt and obligations of the Trust
other than with respect to the Trust Securities; and (iv) the Trust Agreement
further provides that the Issuer Trustees will not cause or permit the Trust to,
among other things, engage in any activity that is not consistent with the
purposes of the Trust.

         Payments of distributions (to the extent funds therefor are available)
and other payments due on the Preferred Securities (to the extent funds therefor
are available) are guaranteed by the Company as and to the extent set forth
under "Description of the Guarantee." If the Company does not make interest
payments on the Convertible Debentures purchased by the Trust, it is expected
that the Trust will not have sufficient funds to pay distributions on the
Preferred Securities. The Guarantee is a guarantee on a subordinated basis with
respect to the Preferred Securities from the time of its issuance but does not
apply to any payment of distributions unless and until the Trust has sufficient
funds for the payment of such distributions.

         The Guarantee covers the payment of distributions and other payments on
the Preferred Securities only if and to the extent that the Company has made a
payment of interest or principal on the Convertible Debentures held by the Trust
as its sole asset. The Guarantee, when taken together with the Company's
obligations under the Convertible Debentures and the Indenture and its
obligations under the Trust Agreement, including its obligations to pay costs,
expenses, debts and liabilities of the Trust (other than with respect to the
Trust Securities), will provide a full and unconditional guarantee of amounts on
the Preferred Securities.

         If the Company fails to make interest or other payments on the
Convertible Debentures when due (taking account of any Extension Period), the
Trust Agreement provides a mechanism whereby the holders of the Preferred
Securities, using the procedures described in "Description of the Preferred
Securities--Book-Entry Only Issuance-The Depository Trust Company" and
"Description of the Preferred Securities--Voting Rights," may direct the
Property Trustee to enforce its rights under the Convertible Debentures. If the
Property Trustee fails to enforce its rights under the Convertible Debentures,
any holder of Preferred Securities may directly institute a legal proceeding
against the Company to enforce the Property Trustee's rights under the
Convertible Debentures without first instituting any legal proceeding against
the Property Trustee or any other person or entity. Notwithstanding the
foregoing, if a Declaration Event of Default has occurred and is continuing and
such event is attributable to the failure of the Company to pay interest or
principal on, the Convertible Debentures on the date such interest or principal
is otherwise payable (or in the case of redemption, on the redemption date),
then a holder of Preferred Securities may institute a Direct Action for




                                       41

<PAGE>   42



payment on or after the respective due date specified in the Convertible
Debentures. In connection with such Direct Action, the Company will be
subrogated to the rights of such holder of Preferred Securities under the
Declaration to the extent of any payment made by the Company to such holder of
Preferred Securities in such Direct Action. The Company, under the Guarantee,
acknowledges that the Guarantee Trustee shall enforce the Guarantee on behalf of
the holders of the Preferred Securities. If the Company fails to make payments
under the Guarantee, the Guarantee provides a mechanism whereby the holders of
the Preferred Securities may direct the Guarantee Trustee to enforce its rights
thereunder. If the Guarantee Trustee fails to enforce the Guarantee, any holder
of Preferred Securities may directly institute a legal proceeding against the
Company to enforce the Guarantee Trustee's rights under the Guarantee without
first instituting a legal proceeding against the Trust, the Guarantee Trustee,
or any other person or entity.



                          DESCRIPTION OF CAPITAL STOCK

         The Company's authorized capital stock currently consists of 50,000,000
shares of Company Common Stock, $.01 par value per share, and 1,000,000 shares
of serial Preferred Stock, par value $.01 per share (the "Company Preferred
Stock"). As of May 8, 1998, there were (i) 29,473,654 shares of Company Common
Stock issued and outstanding, excluding 271,873 shares subject to restricted
stock agreements, (ii) 833,385 shares of Company Common Stock reserved for
issuance upon exercise of outstanding options, and (iii) no shares of Preferred
Stock outstanding.

COMPANY COMMON STOCK

         Each holder of Company Common Stock is entitled to one vote per share
on all matters to be voted on by the shareholders. The Charter does not provide
for cumulative voting and, accordingly, the holders of a majority of the
outstanding shares have the power to elect all directors and to control the
resolution of all issues put to a vote of the shareholders. There are no
preemptive or other subscription rights, conversion rights, or redemption or
sinking fund provisions with respect to shares of the Company Common Stock. All
shares of the Company Common Stock outstanding upon consummation of the Offering
will be validly issued, fully paid, and nonassessable. The shares of Company
Common Stock have the following rights, subject, in each case, to the rights of
the holders of any outstanding Company Preferred Stock: (i) to receive
dividends, if any, as may be declared and paid from time to time by the Board of
Directors, in its discretion, from funds legally available therefore; and (ii)
upon liquidation, dissolution, or winding up of the Company, to receive pro rata
all assets remaining available for distribution.

COMPANY PREFERRED STOCK

         The Company's Board of Directors may authorize, without further action
by the Company's shareholders, the issuance of up to 1,000,000 shares of Company
Preferred Stock in one or more series, and may fix by resolution, to the extent
permitted by the Tennessee Business Corporation Act, the terms and rights of
each such series, including the voting powers, full or limited, if any, of the
shares of such series and the designations, preferences, and relative,
participating, optional, or other special rights, and qualifications,
limitations, or restrictions thereof. The issuance of Company Preferred Stock by
action of the Board of Directors could adversely affect the voting power,
dividend rights and other rights of holders of the Company Common Stock.
Issuance of a series of Company Preferred Stock could also, depending on the
terms of such series, either impede or facilitate the completion of a merger,
tender offer, or other takeover attempt. Although the Board of Directors is
required to make a determination as to the best interests of the shareholders of
the Company when issuing Company Preferred Stock, the Board of Directors could
act in a manner that would discourage an acquisition attempt or other
transaction that some, or a majority, of the shareholders might believe to be in
the best interests of the Company or in which shareholders might receive a
premium for their stock over the then prevailing market price.

                      UNITED STATES FEDERAL INCOME TAXATION

GENERAL

         The following is a summary of certain of the material United States
federal income tax consequences of the purchase, ownership, disposition and
conversion of Preferred Securities. Unless otherwise stated, this summary deals
only with Preferred Securities held as capital assets by holders who purchase
the Preferred Securities upon original issuance. This summary addresses the
United States federal income tax considerations to holders of Preferred
Securities who are citizens or residents of the United States, corporations,
partnerships or other entities created or organized in or under the laws of the
United States or any political subdivision thereof or therein, estates, the
income of which is subject to United States federal income taxation regardless
of its source, trusts, if a U.S. court is able to exercise primary supervision
over the trust's administration and one or more United States persons has the
authority to control all of the trust's substantial decisions or other holders
who are otherwise subject to United States federal income taxation on a net
income basis with respect to Preferred Securities ("U.S. Holders") and does not
address the tax consequences to holders of Preferred Securities who are not U.S.
Holders. This summary does not deal with special classes of holders such as
banks, thrifts, real estate investment trusts, regulated investment companies,
insurance companies, common trust funds, dealers in securities or currencies,
tax-exempt investors, or persons that will hold the Preferred Securities as a
position in a "straddle," as part of a "synthetic security" or "hedge," as part
of a "conversion transaction" or other integrated investment or as other than a
capital asset. This summary also does not address the tax consequences to
persons that have a functional currency other than the U.S. Dollar or the tax
consequences to shareholders, partners or beneficiaries of a holder of Preferred
Securities. Further, it does not include any description of any alternative
minimum tax consequences or the tax laws of any state or local government or of
any foreign government that may be applicable to the Preferred Securities. This
summary is based on the Internal Revenue Code of 1986, as amended (the "Code"),
Treasury regulations thereunder and administrative and judicial interpretations
thereof, as of the date hereof, all of which are subject to change, possibly on
a retroactive basis.

CLASSIFICATION OF THE CONVERTIBLE DEBENTURES

         The Company intends to take the position that the Convertible
Debentures will be classified for United States federal income tax purposes as
indebtedness of the Company under current law, and, by acceptance of a Preferred
Security, each holder covenants to treat the Convertible Debentures as
indebtedness and the Preferred Securities as evidence of an indirect beneficial
ownership interest in the Convertible Debentures. No assurance can be given,
however, that such position of the Company will not be challenged by the
Internal Revenue Service or, if challenged, that such a challenge will not be
successful. The remainder of this discussion assumes that the Convertible
Debentures will be classified as indebtedness of the Company for United States
federal income tax purposes.

CLASSIFICATION OF THE TRUST

         In connection with the issuance of the Preferred Securities, Skadden,
Arps, Slate, Meagher & Flom LLP, special counsel to the Company and the Trust,
rendered its opinion generally to the effect that, under then current law and
assuming full compliance with the terms of the Declaration and the Indenture
(and certain other documents), and based on certain facts and assumptions
contained in such opinion, the Trust will be classified for United Stated
federal income tax purposes as a grantor trust and not as an association taxable
as a corporation. Accordingly, for United States federal income tax purposes,
each holder of Preferred Securities generally will be considered the owner of an
undivided interest in the Convertible Debentures, and each holder will be
required to include in its gross income any interest (or OID) with respect to
its allocable share of those Convertible Debentures.

INTEREST INCOME AND ORIGINAL ISSUE DISCOUNT

         Under Treasury regulations applicable to debt instruments issued on or
after August 13, 1996 (the "Regulations"), a "remote" contingency that stated
interest will not be timely paid will be ignored in determining whether a debt
instrument is issued with OID. The Company believes that the likelihood of its
exercising its option to defer payments is remote within the meaning of the
Regulations. Based on the foregoing, the Company believes that, although the
matter is not free from doubt, the Convertible Debentures will not be considered
to be issued with OID at the time of their original issuance and, accordingly,
that a holder of the Preferred Securities should include in gross income such
holder's allocable share of interest on the Convertible Debentures in accordance
with such holder's method of tax accounting.

         Under the Regulations, if the option to defer any payment of interest
was determined not to be "remote" or if the Company exercised such option, the
Convertible Debentures would be treated as issued with OID at the time of
issuance, or at the time of such exercise, as the case may be, and all stated
interest on the Convertible Debentures would thereafter be treated as OID as
long as the Convertible Debentures remain outstanding. In such event, all of the
holder's taxable interest income with respect to the Convertible Debentures
would constitute OID that would have to be included in income on an economic
accrual basis before the receipt of cash attributable to the interest,
regardless of such holder's method of tax accounting, and actual distributions
of stated interest would not be reported as taxable income.




                                       43

<PAGE>   44



Consequently, holders of Preferred Securities would be required to include in
gross income OID even though the Company would not make any actual cash payments
during the extension period.

         No rulings or other interpretations have been issued by the Internal
Revenue Service ("IRS") which have addressed the meaning of the term "remote" as
used in the Regulations, and it is possible that the IRS could take a position
contrary to the interpretation herein.

         Because income on the Preferred Securities will constitute interest or
OID, corporate holders of Preferred Securities will not be entitled to a
dividends-received deduction with respect to any income recognized with respect
to the Preferred Securities.

RECEIPT OF CONVERTIBLE DEBENTURES OR CASH UPON LIQUIDATION OF THE TRUST

         Under certain circumstances, as described under the caption
"Description of the Preferred Securities--Special Event Redemption or
Distribution," Convertible Debentures may be distributed to holders in exchange
for the Preferred Securities and in liquidation of the Trust. Under current law,
such a distribution to holders, for United States federal income tax purposes,
would be treated as a nontaxable event to each holder, and each holder would
receive an aggregate tax basis in the Convertible Debentures equal to such
holder's aggregate tax basis in its Preferred Securities. A holder's holding
period in the Convertible Debentures so received in liquidation of the Trust
would include the period during which the Preferred Securities were held by such
holder. If, however, the related Special Event is a Tax Event which results in
the Trust being treated as an association taxable as a corporation, the
distribution would likely constitute a taxable event to holders of the Preferred
Securities, in which event the Company would generally be required to redeem the
Convertible Debentures and distribute the resulting cash in liquidation of the
Trust.

         Under certain circumstances described herein (see "Description of the
Preferred Securities"), the Convertible Debentures may be redeemed for cash and
the proceeds of such redemption distributed to holders in redemption of their
Preferred Securities. Under current law, such a redemption would, for United
States federal income tax purposes, constitute a taxable disposition of the
redeemed Preferred Securities, and a holder would recognize gain or loss as if
it sold such redeemed Preferred Securities for cash. See "--Sales of Preferred
Securities."

SALES OF PREFERRED SECURITIES

         A holder that sells Preferred Securities will be considered to have
disposed of all or part of his pro rata share of the Convertible Debentures and
will recognize gain or loss equal to the difference between its adjusted tax
basis in the Preferred Securities and the amount realized on the sale of such
Preferred Securities. Assuming that the Company does not exercise its option to
defer payment of interest on the Convertible Debentures and that the Convertible
Debentures are not deemed to be issued with OID, a holder's adjusted tax basis
in the Preferred Securities will generally be its initial purchase price. If the
Convertible Debentures are deemed to be issued with OID, a holder's tax basis in
the Preferred Securities generally will be its initial purchase price, increased
by OID previously includible in such holder's taxable income to the date of
disposition and decreased by distributions or other payments received on the
Preferred Securities since and including the date that the Convertible
Debentures were deemed to be issued with OID. Such gain or loss generally will
be capital gain or loss (except to the extent of any accrued interest with
respect to such holder's pro rata share of the Preferred Securities required to
be included in income as ordinary income). Under the Taxpayer Relief Act of
1997, net capital gain (i.e., generally, capital gain in excess of capital loss)
recognized by an individual from the sale of a capital asset that has been held
for more than 18 months will be subject to tax at a rate not to exceed 20%,
capital gain from the sale of an asset held for more than 12 months but not more
than 18 months will be subject to tax at a rate not to exceed 28%, and capital
gain recognized from the sale of a capital asset that has been held for 12
months or less will be subject to tax at ordinary income tax rates. In addition,
capital gain recognized by a corporate taxpayer will be subject to tax at the
ordinary income tax rates applicable to corporations. If the selling price is
less than the holder's adjusted tax basis, such holder will recognize tax loss,
and subject to certain limited exceptions, capital losses cannot be applied to
offset ordinary income for United State federal income tax purposes.

         Should the Company exercise its option to defer any payment of interest
on the Convertible Debentures, the Preferred Securities may trade at a price
that does not accurately reflect the value of the accrued but unpaid interest
with respect to the underlying Convertible Debentures. In such event, a holder
who disposes of its Preferred Securities between record dates for payments of
distributions thereon will be required to include in income as ordinary income
accrued but unpaid interest on the Convertible Debentures through the date of
disposition and to add such amount to its adjusted tax basis in its pro rata
share of the underlying Convertible Debentures deemed disposed of. To the extent
that the selling price is less than the holder's adjusted tax basis (which will
include, in the form of OID, all accrued but unpaid interest), such holder will
recognize a capital loss.





                                       44

<PAGE>   45



ADJUSTMENT OF CONVERSION PRICE

         Treasury Regulations promulgated under Section 305 of the Code would
treat holders of Preferred Securities as having received a constructive
distribution from the Company in the event the conversion ratio of the
Convertible Debentures were adjusted if (i) as a result of such adjustment, the
proportionate interest (measured by the quantum of Company Common Stock into or
for which the Convertible Debentures are convertible or exchangeable) of the
holders of the Preferred Securities in the assets or earnings and profits of the
Company were increased, and (ii) the adjustment was not made pursuant to a bona
fide, reasonable antidilution formula. An adjustment in the conversion ratio
would not be considered made pursuant to such a formula if the adjustment was
made to compensate for certain taxable distributions with respect to the Company
Common Stock. Thus, under certain circumstances, a reduction in the conversion
price for the holders may result in deemed dividend income to holders to the
extent of the current or accumulated earnings and profits of the Company.
Holders of the Preferred Securities would be required to include their allocable
share of such deemed dividend income in gross income but would not receive any
cash related thereto.

INFORMATION REPORTING AND BACKUP WITHHOLDING

         Generally, income on the Preferred Securities will be reported to
holders on Forms 1099, which forms should be mailed to holders of Preferred
Securities by January 31 following each calendar year.

         Payments made on, and proceeds from the sale of, the Preferred
Securities may be subject to a "backup" withholding tax of 31% unless the holder
complies with certain identification requirements. Any withheld amounts will be
allowed as a credit against the holder's United States federal income tax,
provided the required information is provided to the Internal Revenue Service.

         On October 7, 1997, the United States Treasury Department issued final
Treasury regulations governing information reporting and the certification
procedures regarding withholding and backup withholding on certain amounts paid
to non-U.S. Holders after December 31, 1998. Such regulations, among other
things, may change the certification procedures relating to the receipt by
intermediaries of payments on behalf of a beneficial owner of a Preferred
Security. Prospective investors should consult their tax advisors regarding the
effect, if any, of such new regulations on an investment in the Preferred
Securities.

         THE UNITED STATES FEDERAL INCOME TAX DISCUSSION SET FORTH ABOVE IS
INCLUDED FOR GENERAL INFORMATION ONLY AND MAY NOT BE APPLICABLE DEPENDING UPON A
HOLDER'S PARTICULAR SITUATION. HOLDERS SHOULD CONSULT THEIR TAX ADVISORS WITH
RESPECT TO THE TAX CONSEQUENCES TO THEM OF THE PURCHASE, OWNERSHIP AND
DISPOSITION OF THE PREFERRED SECURITIES, INCLUDING THE TAX CONSEQUENCES UNDER
STATE, LOCAL, FOREIGN AND OTHER TAX LAWS AND THE POSSIBLE EFFECTS OF CHANGES IN
UNITED STATES FEDERAL OR OTHER TAX LAWS.

                                 SELLING HOLDERS


         The Preferred Securities were originally issued by the Trust and sold
by the Initial Purchasers in a transaction exempt from the registration
requirements of the Securities Act, to persons reasonably believed by such
Initial Purchasers to be "qualified institutional buyers" (as defined in Rule
144A under the Securities Act), or outside the United States to non-U.S. persons
in offshore transactions in reliance on Regulation S under the Securities Act.
The Selling Holders may from time to time offer and sell pursuant to this
Prospectus any or all of the Preferred Securities and Company Common Stock

underwriting discounts, concessions or commissions from the Selling Holders or
the purchasers of such securities for whom they may act as agents. The Selling

transactions at fixed prices, at prevailing market prices at the time of sale(

otherwise than on such exchanges or in the over-the-counter market or (iv)
through the writing of options. At the time a particular offering of the Offered
Securities is made, a Prospectus Supplement, if required, will be distributed

offered and the terms of the offering, including the name or names of any
underwriters, broker/dealers or agents, any discounts, commissions and other
terms constituting compensation from the Selling Holders and any discounts,
commissions or concessions allowed or reallowed or paid to broker/dealers.

jurisdictions the Offered Securities may not be offered or sold unless they have
been registered or qualified for sale in such jurisdictions or any exemption

ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

         (a) The Tennessee Business Corporation Act (the "TBCA") provides that a
corporation may indemnify any of its directors against liability incurred in
connection with a proceeding if (i) the director acted in good faith, (ii) in
the case of conduct in his or her official capacity with the corporation, the
director reasonably believed such conduct was in the corporation's best
interest, (iii) in all other cases, the director reasonably believed that his or
her conduct was not opposed to the best interest of the corporation, and (iv) in
connection with any criminal proceeding, the director had no reasonable cause to
believe that his or her conduct was unlawful. In actions brought by or in the
right of the corporation, however, the TBCA provides that no indemnification may
be made if the director was adjudged to be liable to the corporation. In cases
where the director is wholly successful, on the merits or otherwise, in the
defense of any proceeding instigated because of his or her status as a director
of a corporation, the TBCA mandates that the corporation indemnify the director
against reasonable expenses incurred in the proceeding. The TBCA also provides
that in connection with any proceeding charging improper benefit to a director,
no indemnification may be made if such director is adjudged liable on the basis
that personal benefit was improperly received. Notwithstanding the foregoing,
the TBCA provides that a court of competent jurisdiction, upon application, may
order that a director be indemnified for reasonable expense if, in consideration
of all relevant circumstances, the court determines that such individual is
fairly and reasonably entitled to indemnification, whether or not the standard
of conduct set forth above was met.

         (b) Article Eleven of the Amended and Restated Charter of the
Registrant sets forth the extent to which officers or directors of the
Registrant may be insured or indemnified against any liabilities which they may
incur. The general effect of such provision is that any person made a party to
any action, suit or proceeding by reason of the fact that he or she is or was a
director or officer of the Registrant will be indemnified by the Registrant
against expenses (including attorney's fees), judgments, fines, and amounts paid
in settlement actually and reasonably incurred by him or her in connection with
such action, suit or proceeding, to the fullest extent permitted under the laws
of the State of Tennessee. In addition, such provision provides that, in the
Registrant's sole discretion, the Registrant may indemnify employees or agents
against such expenses, judgments, fines, and amounts paid in settlement.

         (c) The Company maintains a policy of directors' and officers'
insurance that would in certain instances provide the funds necessary for the
Registrant to meet its obligations under its Amended and Restated Charter.

         (d) The Declaration of the Trust provides that no Trustee, affiliate of
any Trustee, or any officers, directors, shareholders, members, partners,
employees, representatives or agent of the Trust, or any employee or agent of
the Trust or its affiliates (each an "Indemnified Person") shall be liable,
responsible or accountable in damages or otherwise to the Trust or any employee
or agent of the Trust or its affiliates for any loss, damage or claim incurred
by reason of any act or omission performed or omitted by such Indemnified Person
in good faith on behalf of the Trust and in a manner such Indemnified Person
reasonably believed to be within the scope of the authority conferred on such
Indemnified Person by the Declaration or by law, except that an Indemnified
Person shall be liable for any such loss, damage or claim incurred by reason of
such Indemnified Person's gross negligence or willful misconduct with respect to
such acts or omissions. The Declaration of the Trust also provides that to the
fullest extent permitted by applicable law, Central Parking shall indemnify each
Company Indemnified Person who was or is a party or is threatened to be made a
party to any threatened, pending or completed action, suit or proceeding,
whether civil, criminal, administrative or investigative (including an action by
or in the right of the Trust unless such Company Indemnified Person has been
adjudged to be liable to the Trust and the Court of Chancery of Delaware has not
ruled that the Company Indemnified Person is fairly and reasonably entitled to
indemnity) by reason of the fact that he is or was a Company Indemnified Person
from expenses (including attorneys' fees), judgments, fines and amounts paid in
settlement actually and



                                       51

<PAGE>   52



reasonably incurred by such Company Indemnified Person in connection with such
action, suit or proceeding if the Company Indemnified Person acted in good faith
and in manner he reasonably believed to be in or not opposed to the best
interests of the Trust. The Declaration of the Trust further provides that, to
the fullest extent permitted by applicable law, expenses (including legal fees)
incurred by an Indemnified Person in defending any claim, demand, action, suit
or proceeding shall, from time to time, be advanced by Central Parking prior to
the final disposition of such claim, demand, action, suit or proceeding upon
receipt by or an undertaking by or on behalf of the Indemnified Person to repay
such amount if it shall be determined that the Indemnified Person is not
entitled to be indemnified for the underlying cause of action as authorized by
the Declaration. The directors and officers of Central Parking and the Regular
Trustees are covered by insurance policies indemnifying them against certain
liabilities, including certain liabilities arising under the Securities Act of
1933, as amended (the "Securities Act"), which might be incurred by them in such
capacities against which they cannot be indemnified by Central Parking or the
Trust. The Selling Holders will be indemnified by Central Parking and the Trust,
jointly and severally, against certain civil liabilities, including certain
liabilities under the Securities Act, or will be entitled to contribution in
connection therewith. Central Parking and the Trust will be indemnified by the
Selling Holders severally against certain civil liabilities, including certain
liabilities under the Securities Act, or will be entitled to contribution in
connection therewith.

         (b)      Financial Statement Schedules

         The schedules for which provision is made in the applicable accounting
regulations of the Commission are not required under the related instructions or
are inapplicable and, therefore, have been omitted.

ITEM 17.  UNDERTAKINGS.


         The undersigned Registrant hereby undertakes:

         1. 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, that the
Registrant has been advised that in the opinion of the 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 the 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
against the Registrant 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.

         2. For purposes of determining any liability under the Securities Act,
that 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 the 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.

         3. For purposes of determining any liability under the Securities Act,
the information omitted from the form of prospectus filed as part of this
Registration Statement in reliance upon Rule 430A and contained in a form of
prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4) or 497(h)
under the Securities Act shall be deemed to be part of this Registration
Statement as of the time it was declared effective.

         4. For the purpose of determining any liability under the Securities
Act, each post-effective amendment that contains a form of prospectus 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.

         5. To include any material information with respect to the plan of
distribution not previously disclosed in the registration statement or any
material change to such information in the registration statement.

         6. 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.

         7. The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to Section 13(a) or 15(d) of the Securities
Exchange Act of 1934 (and, where applicable, each filing of an employee benefit
plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of
1934) that is incorporated by reference in the 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.

substantially similar tenor signed by such Holders in person or by an agent 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. Proof of execution of any such instrument or of
a writing appointing any such agent shall be sufficient for any purpose of this

              (b) The fact and date of the execution by any Person of any such
instrument or writing may be proved by the affidavit of a witness of such
execution or by a certificate of a notary public or other officer authorized by
law to take acknowledgments of deeds, certifying that the individual signing
such instrument or writing acknowledged to him the execution thereof. Where such
execution is by a signer acting in a capacity other than his individual
capacity, such certificate or affidavit shall also constitute sufficient proof
of his authority. The fact and date of the execution of any such instrument or
writing, or the authority of the Person executing the same, may also be proved
in any other manner which the Trustee or the Company, as the case may be, deems
sufficient.

              (c) The Company may, in the circumstances permitted by the Trust
Indenture Act, fix any day as the record date for the purpose of determining the
Holders of Outstanding Convertible Debentures entitled to give, make or take any
request, demand, authorization, direction, notice, consent, waiver or other
action, or to vote on any action, authorized or permitted to be given or taken
by Holders. If not set by the Company prior to the first solicitation of a
Holder made by any Person in respect of any such action, or, in the case of any
such vote, prior to such vote, the record date for any such action or vote shall
be the 30th day (or, if later, the date of the most recent list of Holders
required to be provided pursuant to Section 701) prior to such first
solicitation or vote, as the case may be. With regard to any record date, only
the Holders on such date (or their duly designated proxies) shall be entitled to
give or take, or vote on, the relevant action.

              (d) The ownership of Convertible Debentures shall be proved by the
Security Register.

              (e) Any request, demand, authorization, direction, notice,
consent, waiver or other Act of the Holder of any Convertible Debenture shall
bind every future Holder of the same Convertible Debenture and the Holder of
every Convertible Debenture issued upon the registration of transfer thereof or
in exchange therefor or in lieu thereof in respect of anything done, omitted or
suffered to be done by the Trustee or the Company in reliance thereon, whether
or not notation of such action is made upon such Convertible Debenture.

Without limiting the foregoing, a Holder entitled hereunder to give or take any
such action with regard to any particular Convertible Debenture may do so with
regard to all or any part of the principal amount of such Convertible Debenture
or by one or more duly appointed agents each of which may do so pursuant to such
appointment with regard to all or any different part of such principal amount.

SECTION 205.               Notices, Etc., to Trustee and the Company.

              Any request, demand, authorization, direction, notice, consent,
waiver or Act of Holders or other document provided or permitted by this
Indenture to be made upon, given or furnished to, or filed with,



                                      -14-
<PAGE>   23

              (a) the Trustee by any Holder or by the Company shall be
sufficient for every purpose hereunder if made, given, furnished or filed in
writing to or with the Trustee at its Corporate Trust Office, Attention:
Corporate Trust & Agency Department, or

              (b) the Company by the Trustee or by any Holder shall be
sufficient for every purpose hereunder (unless otherwise herein expressly
provided) if in writing and mailed, first-class postage prepaid, to the Company
addressed to it at the address of its principal office specified in the first
paragraph of this instrument or at any other address previously furnished in
writing to the Trustee by the Company.

SECTION 206.               Notice to Holders; Waiver.

              Where this Indenture provides for notice to Holders of any event,
such notice shall be sufficiently given (unless otherwise herein expressly
provided) if in writing and mailed, first-class postage prepaid, to each Holder
affected by such event, at such Holder's address as it appears in the Security
Register, not later than the latest date (if any), and not earlier than the
earliest date (if any), prescribed for the giving of such notice. In any case
where notice to Holders is given by mail, neither the failure to mail such
notice, nor any defect in any notice so mailed, to any particular Holder shall
affect the sufficiency of such notice with respect to other Holders. Any notice
when mailed to a Holder in the aforesaid manner shall be conclusively deemed to
have been received by such Holder whether or not actually received by such
Holder. Where this Indenture provides for notice in any manner, such notice may
be waived in writing by the Person entitled to receive such notice, either
before or after the event, and such waiver shall be the equivalent of such
notice. Waivers of notice by Holders shall be filed with the Trustee, but such
filing shall not be a condition precedent to the validity of any action taken in
reliance upon such waiver.

              In case by reason of the suspension of regular mail service or by
reason of any other cause it shall be impracticable to give such notice by mail,
then such notification as shall be made with the approval of the Trustee shall
constitute a sufficient notification for every purpose hereunder.

SECTION 207.               Conflict with Trust Indenture Act.

              If any provision hereof limits, qualifies or conflicts with a
provision of the Trust Indenture Act that is required under such Act to be a
part of and govern this Indenture, the latter provision shall control. If any
provision of this Indenture modifies or excludes any provision of the Trust
Indenture Act that may be so modified or excluded, the latter provision shall be
deemed to apply to this Indenture as so modified or to be excluded, as the case
may be.

are for convenience only and shall not affect the construction hereof.

SECTION 209.               Successors and Assigns.

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

SECTION 211.               Benefits of Indenture.

              Nothing in this Indenture or in the Convertible Debentures,
express or implied, shall give to any Person, other than the parties hereto and
their successors hereunder, the holders of Senior Indebtedness, the holders of
Preferred Securities (to the extent provided herein) and the Holders of
Convertible Debentures, any benefit or any legal or equitable right, remedy or
claim under this Indenture.

SECTION 212.               Governing Law.

              THIS INDENTURE AND THE CONVERTIBLE DEBENTURES SHALL BE GOVERNED BY
AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, WITHOUT
REGARD TO ITS PRINCIPLES OF CONFLICTS OF LAWS.

SECTION 213.               Legal Holidays.

              In any case where any Interest Payment Date, Redemption Date or
Stated Maturity of any Convertible Debenture or the last date on which a Holder
has the right to convert his Convertible Debentures shall not be a Business Day,
then (notwithstanding any other provision of this Indenture or of the
Convertible Debentures) payment of interest or principal or conversion of the
Convertible Debentures need not be made on such date, but may be made on the
next succeeding Business Day (except that, if such Business Day is in the next
succeeding calendar year, such Interest Payment Date, Redemption Date or Stated
Maturity, as the case may be, shall be the immediately preceding Business Day)
with the same force and effect as if made on the Interest Payment Date or
Redemption Date, or at the Stated Maturity or on such last day for conversion,
provided, that no interest shall accrue for the period from and after such
Interest Payment Date, Redemption Date or Stated Maturity, as the case may be.

applicable, the Company and the Trustee, by their execution and delivery of this
Indenture, expressly agree to such terms and provisions and to be bound

              The definitive Convertible Debentures shall be typewritten or

                                   ARTICLE VI

                           The Convertible Debentures

SECTION 601.               Title and Terms.

              The aggregate principal amount of Convertible Debentures that may
be authenticated and delivered under this Indenture is limited to $103,092,775
(or up to $113,402,050 if the over-allotment option is exercised by the Trust in
accordance with the terms and provisions of the Purchase Agreement), except for
Convertible Debentures authenticated and delivered upon registration of transfer
of, or in exchange for, or in lieu of, other Convertible Debentures pursuant to
Section 304, 305, 306, 906, 1109 or 1301.

              The Convertible Debentures shall be known and designated as the "5
1/4% Convertible Subordinated Debentures Due 2028" of the Company. Their Stated
Maturity shall be April 1, 2028, and they shall bear interest at the rate of 5
1/4% per annum, from March 13, 1998 or from the most recent Interest Payment
Date to which interest has been paid or duly provided for, as the case may be,
payable quarterly (subject to deferral as set forth herein), in arrears, on
January 1, April 1, July 1, October 1 (each an "Interest Payment Date") of each
year, commencing July 1, 1998, until the principal thereof is paid or made
available for payment, and they shall be paid to the Person in whose name the
Convertible Debenture is registered at 5:00 p.m. (New York City time) on the
regular record date for such interest installment, which shall be the March 15,
June 15, September 15 and December 15 next preceding such Interest Payment Date
(the "Regular Record Date"). Interest will compound quarterly and will accrue at
the rate of 5 1/4% per annum on any interest installment in arrears for more
than one quarter or during an extension of an interest payment period as set
forth in Section 312 hereof.

              The amount of interest payable for any period will be computed on
the basis of a 360-day year of twelve 30-day months. Except as provided in the
following sentence, the amount of interest payable for any period shorter than a
full quarterly period for which interest in computed, will be computed on the
basis of the actual number of days elapsed per 90-day quarter. In the event that
any date on which interest is payable on the Convertible Debentures is not a
Business Day, then payment of interest payable on such date will be made on the
next succeeding day which is a Business Day (and without any interest or other
payment in respect of any such delay), except that, if such Business Day is in
the next succeeding calendar year, such payment shall be made on the immediately
preceding Business Day, in each case with the same force and effect as if made
on such date.

              If at any time while the Property Trustee is the Holder of any
Convertible Debentures, the Trust or the Property Trustee is required to pay any
taxes, duties, assessments or governmental charges of whatever nature (other
than withholding taxes) imposed by the United States, or any other taxing
authority, then, in any such case, the Company will pay as additional interest
("Additional Interest") on the Convertible




                                      -19-
<PAGE>   28
 
Debentures held by the Property Trustee, such amounts as shall be required so
that the net amounts received and retained by the Trust and the Property Trustee
after paying any such taxes, duties, assessments or other governmental charges
will be not less than the amounts the Trust and the Property Trustee would have
received had no such taxes, duties, assessments or other governmental charges
been imposed.

              The principal of and interest on the Convertible Debentures shall
be payable at the office or agency of the Company in the United States
maintained for such purpose and at any other office or agency maintained by the
Company for such purpose in such coin or currency of the United States of
America as at the time of payment is legal tender for payment of public and
private debts; provided, however, that at the option of the Company payment of
interest may be made by check mailed to the address of the Person entitled
thereto as such address shall appear in the Security Register.

              The Convertible Debentures shall be redeemable as provided in
Article Eleven hereof.

              The Convertible Debentures shall be subordinated in right of
payment to Senior Indebtedness as provided in Article Twelve hereof.

              The Convertible Debentures shall be convertible as provided in
Article Thirteen hereof.

SECTION 602.               Denominations.

              The Convertible Debentures shall be issuable only in registered
form without coupons and only in denominations of $25 and integral multiples
thereof.

SECTION 603.               Execution, Authentication, Delivery and Dating.

              The Convertible Debentures shall be executed on behalf of the
Company by its Chairman of the Board, its Vice Chairman of the Board, its Chief
Executive Officer, its President or one of its Vice Presidents, under its
corporate seal reproduced thereon attested by its Secretary or one of its
Assistant Secretaries. The signature of any of these officers on the Convertible
Debentures may be manual or facsimile.

              Convertible Debentures 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 or any of them have
ceased to hold such offices prior to the authentication and delivery of such
Convertible Debentures or did not hold such offices at the date of such
Convertible Debentures.

              At any time and from time to time after the execution and delivery
of this Indenture, the Company may deliver Convertible Debentures executed by
the Company to the Trustee for authentication, together with a Company Order for
the authentication 



                                      -20-
<PAGE>   29
and delivery of such Convertible Debentures; and the Trustee in accordance with
such Company Order shall authenticate and make available for delivery such
Convertible Debentures as in this Indenture provided and not otherwise.

              No Convertible Debenture shall be entitled to any benefit under
this Indenture or be valid or obligatory for any purpose unless there appears on
such Convertible Debenture a certificate of authentication substantially in the
form provided for herein executed by the Trustee by manual signature, and such
certificate upon any Convertible Debenture shall be conclusive evidence, and the
only evidence, that such Convertible Debenture has been duly authenticated and
delivered hereunder.

SECTION 604.               Temporary Convertible Debentures.

              Pending the preparation of definitive Convertible Debentures, the
Company may execute, and upon Company Order the Trustee shall authenticate and
deliver, temporary Convertible Debentures which are typewritten, printed,
lithographed or otherwise produced, in any authorized denomination,
substantially of the tenor of the definitive Convertible Debentures in lieu of
which they are issued and with such appropriate insertions, omissions,
substitutions and other variations as the officers executing such Convertible
Debentures may determine, as evidenced by their execution of such Convertible
Debentures.

              If temporary Convertible Debentures are issued, the Company will
cause definitive Convertible Debentures to be prepared without unreasonable
delay. After the preparation of definitive Convertible Debentures, the temporary
Convertible Debentures shall be exchangeable for definitive Convertible
Debentures upon surrender of the temporary Convertible Debentures at any office
or agency of the Company designated pursuant to Section 1002, without charge to
the Holder. Upon surrender for cancellation of any one or more temporary
Convertible Debentures the Company shall execute and the Trustee shall
authenticate and make available for delivery in exchange therefor a like
principal amount of definitive Convertible Debentures of authorized
denominations. Until so exchanged the temporary Convertible Debentures shall in
all respects be entitled to the same benefits under this Indenture as definitive
Convertible Debentures.

SECTION 605.               Registration, Registration of Transfer and Exchange.

              The Company shall cause to be kept at the Corporate Trust Office
of the Trustee a register (the register maintained in such office and in any
other office or agency designated pursuant to Section 1002 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 Convertible Debentures and of transfers of Convertible
Debentures. The Trustee is hereby appointed "Security Registrar" for the purpose
of registering Convertible Debentures and transfers of Convertible Debentures
as herein provided.



                                      -21-
<PAGE>   30

              Upon surrender for registration of transfer of any Convertible
Debenture at an office or agency of the Company designated pursuant to Section
1002 for such purpose, the Company shall execute, and the Trustee shall
authenticate and deliver, in the name of the designated transferee or
transferees, one or more new Convertible Debentures of any authorized
denominations and of a like aggregate principal amount.

              At the option of the Holder, Convertible Debentures may be
exchanged for other Convertible Debentures of any authorized denominations and
of a like aggregate principal amount, upon surrender of the Convertible
Debentures to be exchanged at such office or agency. Whenever any Convertible
Debentures are so surrendered for exchange, the Company shall execute, and the
Trustee shall authenticate and make available for delivery, the Convertible
Debentures which the Holder making the exchange is entitled to receive.

              All Convertible Debentures issued upon any registration of
transfer or exchange of Convertible Debentures shall be the valid obligations of
the Company, evidencing the same debt, and entitled to the same benefits under
this Indenture, as the Convertible Debentures surrendered upon such registration
of transfer or exchange.

              Every Convertible Debenture presented or surrendered for
registration of transfer or for 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 shall be made for any registration of transfer
or exchange of Convertible Debentures, but 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 of transfer or exchange of Convertible
Debentures, other than exchanges pursuant to Section 304, 906, 1109 or 1301 not
involving any transfer.

SECTION 606.           Mutilated, Destroyed, Lost and Stolen Convertible
                       Debentures.

              If any mutilated Convertible Debenture is surrendered to the
Trustee, the Company shall execute and the Trustee shall authenticate and
deliver in exchange therefor a new Convertible Debenture of like tenor and
principal amount and bearing a number not contemporaneously outstanding.

              If there shall be delivered to the Company and the Trustee (i)
evidence to their satisfaction of the destruction, loss or theft of any
Convertible Debenture and (ii) such Convertible Debenture or indemnity as may be
required by them to save each of them and any agent of either of them harmless,
then, in the absence of notice to the Company or the Trustee that such
Convertible Debenture has been acquired by a bona fide purchaser, the Company
shall execute and the Trustee shall authenticate and deliver, in lieu of any
such




                                      -22-
<PAGE>   31

destroyed, lost or stolen Convertible Debenture, a new Convertible Debenture of
like tenor and principal amount and bearing a number not contemporaneously
outstanding.

              In case any such mutilated, destroyed, lost or stolen Convertible
Debenture has become or is about to become due and payable, the Company in its
discretion may, instead of issuing a new Convertible Debenture, pay such
Convertible Debenture.

              Upon the issuance of any new Convertible Debenture 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 relation thereto and any
other expenses (including the fees and expenses of the Trustee) connected
therewith.

              Every new Convertible Debenture issued pursuant to this Section in
lieu of any destroyed, lost or stolen Convertible Debenture shall constitute an
original additional contractual obligation of the Company, whether or not the
destroyed, lost or stolen Convertible Debenture 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 Convertible Debentures 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 Convertible
Debentures.

SECTION 607.               Payment of Interest; Interest Rights Preserved.

              Interest on any Convertible Debenture 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 that Convertible Debenture (or one or more
Predecessor Securities) is registered at 5:00 p.m. (New York City time) on the
Regular Record Date.

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

              (a) The Company may elect to make payment of any Defaulted
Interest to the Persons in whose names the Convertible Debentures (or their
respective Predecessor Securities) are registered at 5:00 p.m. (New York City
time) 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
Convertible Debenture 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



                                      -23-
<PAGE>   32

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 (a)
provided. Thereupon the Trustee shall fix a Special Record Date for the payment
of such Defaulted Interest which 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 each Holder at his address as it appears
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 so mailed, such Defaulted Interest shall be
paid to the Persons in whose names the Convertible Debentures (or their
respective Predecessor Securities) are registered at 5:00 p.m. (New York City
time) on such Special Record Date and shall no longer be payable pursuant to the
following Clause (b).

              (b) The Company may make payment of any Defaulted Interest in any
other lawful manner not inconsistent with the requirements of any securities
exchange on which the Convertible Debentures may be listed, and, if so listed,
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 (B),
such manner of payment shall be deemed practicable by the Trustee.

              Subject to the foregoing provisions of this Section 307, each
Convertible Debenture delivered under this Indenture upon registration of
transfer of or in exchange for or in lieu of any other Convertible Debenture
shall carry the rights to interest accrued and unpaid, and to accrue (including
in each such case Additional Payments, if any), which were carried by such other
Convertible Debenture.

              In the case of any Convertible Debenture which is converted after
any Regular Record Date and on or prior to the next succeeding Interest Payment
Date (other than any Convertible Debenture whose Maturity is prior to such
Interest Payment Date), interest whose Stated Maturity is on such Interest
Payment Date shall be payable on such Interest Payment Date notwithstanding such
conversion, and such interest (whether or not punctually paid or duly provided
for) shall be paid to the Person in whose name that Convertible Debenture (or
one or more Predecessor Securities) is registered at 5:00 p.m. (New York City
time) on such Regular Record Date. Except as otherwise expressly provided in the
immediately preceding sentence, in the case of any Convertible Debenture that
is converted prior to any Regular Record Date, interest whose Stated Maturity is
after the date of conversion of such Convertible Debenture shall not be payable,
and the Company shall not make nor be required to make any other payment,
adjustment or allowance with respect to accrued but unpaid interest (including
Additional Payments, if any) on the Convertible Debentures being converted,
which shall be deemed to be paid in full. Subject to any right of the Holder of
such Convertible Debenture or any Predecessor Security to receive interest



                                      -24-
<PAGE>   33

as provided in this paragraph and the second paragraph of Clause (a) of Section
1302, the Company's delivery upon conversion of the fixed number of shares of
Company Common Stock into which the Convertible Debentures are convertible
(together with the cash payment, if any, in lieu of fractional shares) shall be
deemed to satisfy the Company's obligation to pay the principal amount at
Maturity of the portion of Convertible Debentures so converted and any unpaid
interest (including Additional Payments, if any) accrued on such Convertible
Debentures at the time of such conversion. If any Convertible Debenture called
for redemption is converted, any money deposited with the Trustee or with any
Paying Agent or so segregated and held in trust for the redemption of such
Convertible Debenture shall (subject to any right of the Holder of such
Convertible Debenture or any Predecessor Security to receive interest as
provided in this paragraph) be paid to the Company upon Company Request or, if
then held by the Company, shall be discharged from such trust.

SECTION 608.               Persons Deemed Owners.

              Prior to due presentment of a Convertible Debenture for
registration of transfer, the Company, the Trustee and any agent of the Company
or the Trustee may treat the Person in whose name such Convertible Debenture is
registered as the owner of such Convertible Debenture for the purpose of
receiving payment of principal of and (subject to Section 307) interest
(including Additional Payments, if any) on such Convertible Debenture and for
all other purposes whatsoever, whether or not such Convertible Debenture 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.

SECTION 609.               Cancellation.

              All Convertible Debentures surrendered for payment, redemption,
registration of transfer or exchange or conversion shall, if surrendered to any
Person other than the Trustee, be delivered to the Trustee and shall be promptly
cancelled by it. The Company may at any time deliver to the Trustee for
cancellation any Convertible Debentures previously authenticated and delivered
hereunder which the Company may have acquired in any manner whatsoever, and all
Convertible Debentures so delivered shall be promptly cancelled by the Trustee.
No Convertible Debentures shall be authenticated in lieu of or in exchange for
any Convertible Debentures cancelled as provided in this Section, except as
expressly permitted by this Indenture. All cancelled Convertible Debentures held
by the Trustee shall be disposed of as directed by a Company Order; provided,
however, that the Trustee shall not be required to destroy the certificates
representing such cancelled Convertible Debentures.

SECTION 610.               Right of Set Off.

              Notwithstanding anything to the contrary in this Indenture, the
Company shall have the right to set off any payment it is otherwise required to
make hereunder to the extent the Company has theretofore made, or is
concurrently on the date of such payment making, a payment under the Guarantee.



                                      -25-
<PAGE>   34

SECTION 611.               CUSIP Numbers.

              The Company in issuing the Convertible Debentures may use "CUSIP"
numbers (if then generally in use), and, if so, the Trustee shall use "CUSIP"
numbers in notices of redemption as a convenience to Holders; provided, that any
such notice may state that no representation is made as to the correctness of
such numbers either as printed on the Convertible Debentures or as contained in
any notice of a redemption and that reliance may be placed only on the other
identification numbers printed on the Convertible Debentures, and any such
redemption shall not be affected by any defect in or omission of such numbers.

SECTION 612.               Option to Extend Interest Payment Period.

              (a) Provided that no Event of Default has occurred and is
continuing, the Company shall have the right at any time during the term of the
Convertible Debentures to defer interest payments (including Additional
Payments) from time to time by extending the interest payment period for
successive periods (each, an "Extension Period") not exceeding 20 consecutive
quarters for each such period; provided, no Extension Period may extend beyond
the maturity date of the Convertible Debentures. At the end of each Extension
Period, the Company shall pay all interest then accrued and unpaid (including
Additional Interest) together with interest thereon compounded quarterly at the
rate specified for the Convertible Debentures to the extent permitted by
applicable law ("Compounded Interest"); provided, that during any Extension
Period, the Company shall (i) not declare or pay dividends on, or make a
distribution with respect to, or redeem or purchase or acquire, or make a
liquidation payment with respect to, any of its capital stock (other than (A)
purchases or acquisitions of shares of Company Common Stock in connection with
the satisfaction by the Company of its obligations under any employee benefit
plans or the satisfaction by the Company of its obligations pursuant to any
contract or security requiring the Company to purchase shares of Company Common
Stock, (B) as a result of a reclassification of the Company's capital stock or
the exchange or conversion of one class or series of the Company's capital stock
for another class or series of the Company's capital stock or (C) the purchase
of fractional interests in shares of the Company's capital stock pursuant to the
conversion or exchange provisions of such capital stock or the security being
converted or exchanged) or make any guarantee payments with respect to the
foregoing, (ii) not make any payment of interest, principal or premium, if any,
on or repay, repurchase or redeem any debt securities (including guarantees)
issued by the Company that rank pari passu with or junior to the Convertible
Debentures (except by conversion into or exchange for shares of its capital
stock) and (iii) not make any guarantee payments with respect to the foregoing
(other than pursuant to the Guarantee). Prior to the termination of any such
Extension Period, the Company may further extend such Extension Period;
provided, that such Extension Period, together with all such previous and
further extensions thereof, may not exceed 20 consecutive quarters or extend
beyond the maturity date of the Convertible Debentures. Upon the termination of
any Extension Period and the payment of all amounts then due, the



                                      -26-
<PAGE>   35

Company may commence a new Extension Period, subject to the above requirements.
No interest during an Extension Period, except at the end thereof, shall be due
and payable. Notwithstanding any other provision in this Indenture to the
contrary, the Company shall not have the right at any time to defer any
Additional Interest, including by extending the interest payment period.

              (b) If the Property Trustee is the sole Holder of the Convertible
Debentures at the time the Company selects an Extension Period, the Company
shall give written notice to the Administrative Trustees and the Property
Trustee of its selection of such Extension Period at least one Business Day
prior to the earlier of (i) the date the distributions on the Preferred
Securities are payable or (ii) if the Preferred Securities are listed on the New
York Stock Exchange or other stock exchange or quotation system, the date the
Trust is required to give notice to the New York Stock Exchange or other
applicable self-regulatory organization or to holders of the Preferred
Securities of the record date or the date such distributions are payable, but in
any event not less than 10 Business Days prior to such record date. The Company
shall cause the Trust to give notice of the Company's selection of such
Extension Period to the holders of the Preferred Securities.

              (c) If the Property Trustee is not the sole holder of the
Convertible Debentures at the time the Company selects an Extension Period, the
Company shall give the Holders of the Convertible Debentures and the Trustee
written notice of its selection of such Extension Period at least 10 Business
Days prior to the earlier of (i) the next succeeding Interest Payment Date or
(ii) if the Preferred Securities are listed on the New York Stock Exchange or

SECTION 613.              Paying Agent, Security Registrar and Conversion Agent.

<PAGE>   36




                           (1)  the Convertible Debentures in certificated form
may be presented to the Trustee by the Property Trustee in exchange for a global
Convertible Debenture in an aggregate principal amount equal to the aggregate
principal amount of all outstanding Convertible Debentures (a "Global
Security"), to be registered in the name of the Depositary, or its nominee, and
delivered by the Trustee to the Depositary for crediting to the accounts of its
participants pursuant to the instructions of the Administrative Trustees. The
Company upon any such presentation shall execute a Global Security in such
aggregate principal amount and deliver the same to the Trustee for
authentication and delivery in accordance with this Indenture. Payments on the
Convertible Debentures issued as a Global Security will be made to the
Depositary; and

                           (2)  if any Preferred Securities are held in non
book-entry certificated form, the Convertible Debentures in certificated form
may be presented to the Trustee by the Property Trustee and any Preferred
Security Certificate which represents Preferred Securities other than Preferred
Securities held by the Depositary or its nominee ("Non Book-Entry Preferred
Securities") will be deemed to represent beneficial interests in Convertible
Debentures presented to the Trustee by the Property Trustee having an aggregate
principal amount equal to the aggregate liquidation amount of the Non Book-Entry
Preferred Securities until such Preferred Security Certificates are presented to
the Security Registrar for transfer or reissuance at which time such Preferred
Security Certificates will be cancelled and a Convertible Debenture, registered
in the name of the holder of the Preferred Security Certificate or the
transferee of the holder of such Preferred Security Certificate, as the case may
be, with an aggregate principal amount equal to the aggregate liquidation amount
of the Preferred Security Certificate cancelled, will be executed by the Company
and delivered to the Trustee for authentication and delivery in accordance with
this Indenture. On issue of such Convertible Debentures, Convertible Debentures
with an equivalent aggregate principal amount that were presented by the
Property Trustee to the Trustee will be deemed to have been cancelled.

                  (b) A Global Security may be transferred, in whole but not in
part, only to another nominee of the Depositary, or to a nominee of such
successor Depositary.

                  (c) If (i) the Depositary notifies the Company that it is
unwilling or unable to continue as a depositary for such Global Security and no
successor depositary shall have been appointed, (ii) the Depositary, at any
time, ceases to be a clearing agency registered under the Exchange Act at which
time the Depositary is required to be so registered to act as such depositary
and no successor depositary shall have been appointed, (iii) the Company, in
its sole discretion, determines that such Global Security shall be so
exchangeable or (iv) there shall have occurred an Event of Default with respect
to such Convertible Debentures, as the case may be, the Company will execute,
and, subject to Article Three of this Indenture, the Trustee, upon written
notice from the Company and receipt of a Company Order, will authenticate and
deliver the Convertible Debentures in definitive registered form without
coupons, in authorized denominations, and in an aggregate principal amount equal
to the principal amount of the Global Security in exchange for such Global
Security. In addition,



                                      -28-
<PAGE>   37

upon an Event of Default or if the Company may at any time determine that the
Convertible Debentures shall no longer be represented by a Global Security, in
such event the Company will execute, and subject to Section 305 of this
Indenture, the Trustee, upon receipt of an Officers' Certificate evidencing such
determination by the Company, will authenticate and make available for delivery
the Convertible Debentures in definitive registered form without coupons, in
authorized denominations, and in an aggregate principal amount equal to the
principal amount of the Global Security in exchange for such Global Security.
Upon the exchange of the Global Security for such Convertible Debentures in
definitive registered form without coupons, in authorized denominations, the
Global Security shall be cancelled by the Trustee. Such Convertible Debentures
in definitive registered form issued in exchange for the Global Security shall
be registered in such names and in such authorized denominations as the
Depositary, pursuant to instructions from its direct or indirect participants or
otherwise, shall instruct the Trustee. The Trustee shall deliver such
Convertible Debentures to the Depositary for delivery to the Persons in whose
names such Convertible Debentures are so registered.

              (d) Every Global Security authenticated and delivered hereunder
shall bear a legend in substantially the following form, in capital letters and
bold-face type:

         THIS CONVERTIBLE DEBENTURE IS A GLOBAL SECURITY WITHIN THE MEANING OF
         THE INDENTURE HEREINAFTER REFERRED TO AND IS REGISTERED IN THE NAME OF
         A DEPOSITARY OR A NOMINEE THEREOF. THIS CONVERTIBLE DEBENTURE MAY NOT
         BE EXCHANGED IN WHOLE OR IN PART FOR A CONVERTIBLE DEBENTURE
         REGISTERED, AND NO TRANSFER OF THIS CONVERTIBLE DEBENTURE IN WHOLE OR
         IN PART MAY BE REGISTERED, IN THE NAME OF ANY PERSON OTHER THAN SUCH
         DEPOSITARY OR A NOMINEE THEREOF, EXCEPT IN THE LIMITED CIRCUMSTANCES
         DESCRIBED IN THE INDENTURE.

              (e) If the Depositary is the Depository Trust Company, the Global
Security authenticated and delivered hereunder shall also bear a legend in
substantially the following form, in capital letters and bold-face type:

         UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED SIGNATORY OF THE
         DEPOSITORY TRUST COMPANY ("DTC") TO THE COMPANY OR ITS AGENT FOR
         REGISTRATION OF TRANSFER, EXCHANGE, OR PAYMENT, AND ANY CERTIFICATE
         ISSUED IS REGISTERED IN THE NAME OF CEDE & CO. OR IN SUCH OTHER NAME AS
         IS REQUESTED BY AN AUTHORIZED

      OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC), ANY

      PERSON IS WRONGFUL INASMUCH AS THE REGISTERED OWNER HEREOF, CEDE & CO.,
      HAS AN INTEREST HEREIN.

              (f) The Convertible Debentures may not be transferred except in
compliance with the Restricted Securities Legend unless otherwise determined by
the Company in accordance with applicable law. Upon any distribution of the
Convertible Debentures to the holders of the Preferred Securities in accordance
with the Trust Agreement, the Company and the Trustee shall enter into a
supplemental indenture pursuant to Section 901(e) to provide for transfer
procedures and restrictions with respect to the Convertible Debentures
substantially similar to those contained in the Trust Agreement to the extent
applicable in the circumstances existing at the time of such distribution.

         and the Company has deposited or caused to be deposited with the
         Trustee as trust funds in trust for the purpose an amount sufficient to

interest for whose payment such money has been deposited with the Trustee. All
moneys deposited with the Trustee pursuant to Section 401 (and held by it or any

SECTION 1002.         Acceleration of Maturity; Rescission and Annulment.

                  If an Event of Default occurs and is continuing, then and in

amount of the Outstand ing Convertible Debentures may declare the principal of
all the Convertible Debentures and any other amounts payable hereunder 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 and
all accrued interest shall become immediately due and payable.

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

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

                           (i)   all overdue interest (including Additional

         which have become due otherwise than by such declaration of
         acceleration and interest thereon at the rate borne by the Convertible
         Debentures, and

                           (iii) all sums paid or advanced by the Trustee
         hereunder and the reasonable compensation, expenses, disbursements and
         advances of the 


                                      -34-

         Trustee, its agents and counsel; 

         and

                  (b) all Events of Default, other than the non-payment of the
principal of Convertible Debentures which have become due solely by such
declaration of acceleration, have been cured or waived as provided in Section
513.

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

SECTION 1003.         Collection of Indebtedness and Suits for Enforcement by 
                      Trustee.

                  The Company covenants that if:

                  (a) default is made in the payment of any interest (including
Additional Payments, if any) on any Convertible Debenture when such interest
becomes due and payable and such default continues for a period of 30 days, or

                  (b) default is made in the payment of the principal of any 
Convertible Debenture at the Maturity thereof,

the Company will, upon demand of the Trustee, pay to it, for the benefit of the
Holders of such Convertible Debentures, the whole amount then due and payable on
such Convertible Debentures for principal and interest (including Additional
Payments, if any) and, to the extent that payment thereof shall be legally
enforceable, interest on any overdue principal and on any overdue interest
(including Additional Payments, if any), at the rate borne by the Convertible
Debentures, 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 an Event of Default occurs and is continuing, the Trustee
may in its discretion proceed to protect and enforce its rights and the rights
of the Holders 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.

SECTION 1004.               Trustee May File Proofs of Claim.

any other obligor upon the Convertible Debentures), its property or its
creditors, the Trustee shall be entitled and empowered, by intervention in such
proceeding or otherwise, to take any and all actions authorized under the Trust
Indenture Act in order to have claims of the Holders and

authorized to collect and receive any moneys or other property payable or
deliverable on any such claims and to distribute the same; and any custodian,
receiver, assignee, trustee, liquidator, sequestrator or other similar official
in any such judicial proceeding is hereby authorized by each Holder to make such
payments to the Trustee and, in the event that the Trustee shall consent to the
making of such payments directly to the Holders, to pay to the Trustee any
amount due 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 607.

                  No provision of this Indenture 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 Convertible Debentures 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.

SECTION 1005.       Trustee May Enforce Claims Without Possession of Convertible
                    Debentures.

Convertible Debentures may be prosecuted and enforced by the Trustee without the
possession of any of the Convertible Debentures or the production thereof in any
proceeding relating thereto, and any such proceeding instituted by the Trustee
shall be brought in its own name as trustee of an express trust, and any
recovery of judgment shall, after provision for the payment of the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel, be for the ratable benefit of the Holders of the Convertible
Debentures in respect of which such judgment has been recovered.

SECTION 1006.       Application of Money Collected.

                  Subject to Article Twelve, any money collected by the Trustee
pursuant to this Article shall be applied in the following order, at the date or

account of principal or interest (including Additional Payments, if any), upon

payment if only partially paid and upon surrender thereof if fully paid:

                  FIRST:  To the payment of all amounts due the Trustee under

         Convertible Debentures for principal and interest (including Additional
         Payments, if any), respectively.

Trustee of a continuing Event of Default;

                  (b) if the Trust is not the sole holder of Convertible

Trustee to institute proceedings in respect of such Event of Default in its own
name as Trustee hereunder;

                  (c) such Holder or Holders have offered to the Trustee
reasonable indemnity against the costs, expenses and liabilities to be incurred

it being understood and intended that no one or more 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 Holders,

or to enforce any right under this Indenture, except in the manner herein
provided and for the equal and ratable benefit of all the Holders.

SECTION 1009.              Restoration of Rights and Remedies.

                  If the Trustee or any Holder has instituted any proceeding to
enforce any right or remedy under this Indenture and such proceeding has been
discontinued or abandoned for any reason, or has been determined adversely to
the Trustee or to such Holder, then and in every such case, subject to any
determination in such proceeding, the Company, the Trustee and the Holders shall
be restored severally and respectively to their former positions hereunder and
thereafter all rights and remedies of the Trustee and the Holders shall continue

or payment of mutilated, destroyed, lost or stolen Convertible Debentures in the
last paragraph of Section 306, 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.

                  Subject to Section 902 hereof, the Holders of not less than a
majority in principal amount of the Outstanding Convertible Debentures may on
behalf of the Holders of all the Convertible Debentures waive any past default
hereunder and its consequences, except a default

                  (a) in the payment of the principal of, premium, if any, or
interest (including Additional Payments, if any) on any Convertible Debenture
(unless such default has been cured and a sum sufficient to pay all matured
installments of interest and principal due otherwise than by acceleration has
been deposited with the Trustee); or

                  (b) in respect of a covenant or provision hereof that under
Article Nine cannot be modified or amended without the consent of the Holder of
each Outstanding Security affected; provided, however, that if the Convertible
Debentures are held by the Trust or a trustee of the Trust, such waiver shall
not be effective until the holders of a majority in liquidation amount of Trust
Securities shall have consented to such waiver; provided, further, that if the
consent of the Holder of each outstanding Convertible Debenture is required,
such waiver shall not be effective until each holder of the Trust Securities
shall have consented to such waiver.

                  Upon any such waiver, such default shall cease to exist, and
any Event of Default arising therefrom shall be deemed to have been cured, for
every purpose of this Indenture; but no such waiver shall extend to any
subsequent or other default or impair any right consequent thereon.

SECTION 1014.              Undertaking for Costs.

                  In any suit for the enforcement of any right or remedy under
this Inden ture, or in any suit against the Trustee for any action taken,
suffered or omitted by it as Trustee, a court may require any party litigant in
such suit to file an undertaking to pay the costs of such suit, and may assess
costs against any such party litigant, in the manner and to the extent provided
in the Trust Indenture Act; provided, that neither this Section nor the Trust
Indenture Act shall be deemed to authorize any court to require such an
undertaking or to make such an assessment in any suit instituted by the Company
or the Trustee or in any suit for the enforcement of the right to receive the
principal of and interest (including Additional Payments, if any) on any
Convertible Debenture or to convert any Convertible Debenture in accordance with
Article Thirteen.

SECTION 1015.              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 


                                      -39-

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.

SECTION 1016.              Enforcement by Holders of Preferred Securities.

                  Notwithstanding the foregoing, if an Event of Default has
occurred and is continuing and such event is attributable to the failure of the
Company to pay interest or principal on the Convertible Debentures on the date
such interest or principal is otherwise payable, the Company acknowledges that,
in such event, a holder of Preferred Securities may institute a Direct Action
for payment on or after the respective due date specified in the Convertible
Debentures. The Company may not amend this Indenture to remove the foregoing
right to bring a Direct Action without the prior written consent of all the
holders of Preferred Securities. Notwithstanding any payment made to such holder
of Preferred Securities by the Company in connection with a Direct Action, the
Company shall remain obligated to pay the principal of and interest on the
Convertible Debentures (including Additional Payments, if any) held by the Trust
or the Property Trustee and the Company shall be subrogated to the rights of the
holder of such Preferred Securities with respect to payments on the Preferred
Securities to the extent of any payments made by the Company to such holder in
any Direct Action. The holders of Preferred Securities will not be able to
exercise directly any other remedy available to the Holders of the Convert ible
Debentures.

costs, expenses and liabilities which might be incurred by it in compliance with
such request or direction;

                  (f) the Trustee shall not be bound to make any investigation
into the facts or matters stated in any resolution, certificate, statement,

debenture, note, other evidence of indebtedness or other paper or document, but
the Trustee, in its discretion, may make such further inquiry or investigation

or negligence on the part of any agent or attorney appointed with due care by it
hereunder; and

                  (h) the Trustee shall not be liable for any action taken,
suffered, or omitted to be taken by it in good faith, without gross negligence
or wilful misconduct, and reasonably believed by it to be authorized or within
the discretion or rights or powers conferred upon it by this Indenture.

SECTION 1204.              Not Responsible for Recitals or Issuance of

Debentures, 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

SECTION 1206.              Money Held in Trust.

                  Money held by the Trustee in trust hereunder need not be

may adopt such authentication and deliver the Convertible Debentures so
authenticated with the same effect as if such successor Trustee had itself
authenticated such Convertible Debentures.

SECTION 1213.              Preferential Collection of Claims Against Company.

Article Thirteen;

                  (b) immediately after giving effect to such transaction and
treating any indebtedness which becomes an obligation of the Company or a
Subsidiary as a result of such transaction as having been incurred by the
Company or such Subsidiary at the time of such transaction, no Event of Default,
and no event which, after notice or lapse of time or both, would become an Event
of Default, shall have happened and be continuing; and

                  (c) the Company has delivered to the Trustee an Officers'
Certificate and an Opinion of Counsel, each stating that such consolidation,
merger, conveyance, transfer or lease and, if a supplemental indenture is
required in connection with such transaction, such supplemental indenture,
comply with this Article and that all conditions precedent herein provided for
relating to such transaction have been complied with.

substituted for, and may exercise every right and power of, the Company under
this Indenture with the same effect as if such successor Person had been named

of all obligations and covenants under this Indenture and the Convertible
Debentures.

                             Supplemental Indentures

SECTION 1801.              Supplemental Indentures Without Consent of Holders.

                  Without the consent of any Holders, the Company, when
authorized by a Board Resolution, and the Trustee, at any time and from time to
time, may enter into one or more indentures supplemental hereto, in form
satisfactory to the Trustee, for any of the following purposes:

                  (a)  to evidence the succession of another Person to the 
Company and the assumption by any such successor of the covenants of the Company
herein and in the Convertible Debentures; or

                  (b)  to add to the covenants of the Company for the benefit 
of the Holders, or to surrender any right or power herein conferred upon the
Company; or

                  (c)  to make provision with respect to the conversion rights 
of Holders pursuant to the requirements of Article Thirteen; or

                  (d)  to cure any ambiguity, to correct or supplement any
provision herein which may be inconsistent with any other provision herein, or
to make any other provi sions with respect to matters or questions arising under
this Indenture which shall not be inconsistent with the provisions of this
Indenture; provided, that such action pursuant to this Clause (d) shall not
adversely affect the interests of the Holders of the Convertible Debentures or,
so long as any of the Preferred Securities shall remain outstanding, the holders
of the Preferred Securities;

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

to make provision for transfer procedures, certification, book-entry provisions,
the form of restricted securities legends, if any, to be placed on Convertible
Debentures, and all other matters required pursuant to Sections 305 and 314 or

Convertible Debentures to holders of Preferred Securities in the event of a
distribution of Convertible Debentures by the Trust if a Special Event occurs
and is continuing.

SECTION 1802.              Supplemental Indentures with Consent of Holders.

                  With the consent of the Holders of not less than a majority in
principal amount of the Outstanding Convertible Debentures, by Act of said
Holders delivered to the Company and the Trustee, the Company, when authorized
by a Board Resolution, and the 


                                      -51-

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 provi sions of this Indenture or of modifying in any manner the rights of
the Holders under this Indenture; provided, however, that no such supplemental
indenture shall, without the consent of the Holder of each Outstanding Security
affected thereby,

                  (a) extend the Stated Maturity of the principal of, or any
installment of interest (including Additional Payments, if any) on, any
Convertible Debenture, or reduce the principal amount thereof, or reduce the
rate or extend the time for payment of interest thereon, or extend the Extension
Period, or reduce any premium payable upon the redemption thereof, or change the
place of payment where, or the coin or currency in which, any Convertible
Debenture or interest thereon is payable, or impair the right to institute suit
for the enforcement of any such payment on or after the Stated Maturity thereof
(or, in the case of redemption, on or after the Redemption Date), or adversely
affect the right to convert any Convertible Debenture as provided in Article
Thirteen (except as permitted by Section 901(c)), or modify the provisions of
this Indenture with respect to the subordination of the Convertible Debentures
in a manner adverse to the Holders,

reduce the percentage in principal amount of the Outstanding Convertible
Debentures, the consent of whose Holders is required for any such supplemental
indenture, or the consent of whose Holders is required for any waiver (of
compliance with certain provisions of this Indenture or certain defaults
hereunder and their consequences) provided for in this Indenture, or modify any
of the provisions of this Section or Section 513, 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
Security affected thereby;

provided that if the Convertible Debentures are held by the Trust or a trustee
of the Trust, such supplemental indenture shall not be effective until the
holders of a majority in liquidation amount of Trust Securities shall have
consented to such supplemental indenture; provided, further, that if the consent
of the Holder of each Outstanding Security is required, such supplemental
indenture shall not be effective until each holder of the Trust Securities of
the Trust shall have consented to such supplemental indenture.

                  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.

                  The Company may, but shall not be obligated to, fix a record
date for the purpose of determining the Persons entitled to consent to any
indenture supplemental hereto. If a record date is fixed, the Holders on such
record date, or their duly designated proxies, and only such Persons, shall be
entitled to consent to such supplemental inden ture, whether or not such Holders
remain Holders after such record date; provided that unless such consent shall
have become effective by virtue of the requisite percentage having been obtained
prior 


                                      -52-


<PAGE>   61
 

to the date which is 90 days after such record date, any such consent previously
given shall automatically and without further action by any Holder be cancelled
and of no further effect.

SECTION 1803.              Execution of Supplemental Indentures.

                  In executing, or accepting the additional trusts created by,
any supplemental indenture permitted by this Article or the modifications
thereby of the trusts created by this Indenture, the Trustee shall be entitled
to receive, and (subject to Section 601) shall be fully protected in relying
upon, an Opinion of Counsel stating that the execution of such supplemental
indenture is authorized or permitted by this Indenture. The Trustee may, but
shall not be obligated to, enter into any such supplemental indenture which
affects the Trustee's own rights, duties or immunities under this Indenture or
otherwise.

SECTION 1804.              Effect of Supplemental Indentures.

                  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 Convertible Debentures theretofore or thereafter authenticated
and delivered hereunder shall be bound thereby. No such supplemental indenture
shall directly or indirectly modify the provisions of Article Twelve in any
manner which might terminate or impair the rights of the Senior Indebtedness
pursuant to such subordination provisions.

SECTION 1805.              Conformity with Trust Indenture Act.

                  Every supplemental indenture executed pursuant to this Article
shall conform to the requirements of the Trust Indenture Act.

SECTION 1806.              Reference in Convertible Debentures to Supplemental 
                           Indentures.

                  Convertible Debentures authenticated and delivered after the
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
to any matter provided for in such supplemental indenture. If the Company shall
so determine, new Convertible Debentures so modified as to conform, in the
opinion of the Trustee and the Company, to any such supplemental indenture may
be prepared and executed by the Company and authenticated and delivered by the
Trustee in exchange for Outstanding Convertible Debentures.

                    Covenants; Representations and Warranties

SECTION 2001.              Payment of Principal and Interest.

                  The Company will duly and punctually pay the principal of and

accordance with the terms of the Convertible Debentures and this Indenture.

SECTION 2002.              Maintenance of Office or Agency.

                  The Company will maintain in the United States an office or
agency where Convertible Debentures may be presented or surrendered for payment,
where Convertible Debentures may be surrendered for registration of transfer or
exchange and where notices and demands to or upon the Company in respect of the
Convertible Debentures 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 such
presentations, surrenders, notices and demands.

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

SECTION 2003.              Money for Convertible Debenture Payments to Be Held 
                           in Trust.

                  If the Company shall at any time act as its own Paying Agent,
it will, on or before each due date of the principal of or interest on any of
the Convertible Debentures, segregate and hold in trust for the benefit of the
Persons entitled thereto a sum sufficient to pay the principal 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, it
will, prior to each due date of the principal of or interest on any Convertible
Debentures, deposit with a Paying Agent a sum sufficient to pay such amount,
such sum to be held as provided by the 


                                      -54-

Trust Indenture Act, and (unless 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 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 (i) comply with the provisions of the Trust
Indenture Act applicable to it as a Paying Agent and (ii) during the continuance
of any default by the Company (or any other obligor upon the Convertible
Debentures) in the making of any payment in respect of the Convertible
Debentures, upon the written request of the Trustee, forthwith pay to the
Trustee all sums held in trust by such Paying Agent as such.

                  The Company may at any time, for the purpose of obtaining the
satisfac tion 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 or
interest on (including Additional Payments, if any) any Convertible Debenture
and remaining unclaimed for two years after such principal or interest has
become due and payable shall be paid to the Company on Company Request, or (if
then held by the Company) shall be discharged from such trust; and the Holder of
any such Convertible Debenture 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.

SECTION 2004.              Statement by Officers as to Default.

                  The Company will deliver to the Trustee, within 120 days after
the end of each fiscal year of the Company ending after the date hereof, an
Officers' Certificate, stating whether or not to the best knowledge of the
signers thereof the Company is in default in the performance and observance of
any of the material terms, provisions and conditions of this Indenture (without
regard to any period of grace or requirement of notice provided hereunder) and,
if the Company shall be in default, specifying all such defaults and the nature
and status thereof of which they may have knowledge.

SECTION 2005.              Limitation on Dividends; Covenants as to the Trust.

                  (a) The Company covenants that so long as the Convertible
Debentures are outstanding, if (i) there shall have occurred and be continuing

of notice or the lapse of time or both, would constitute an Event of Default,
(ii) the Company shall be in default with respect to its payment of any
obligations under the Guarantee, or (iii) the Company has exercised its option
to defer interest payments on the Convertible Debentures by extending the
interest payment period and such period, or any extension thereof, shall be
continuing, then the Company shall (A) not declare or pay dividends on, or make
a distribution with respect to, or redeem or purchase or acquire, or make a
liquidation payment with respect to, any of its capital stock (other than (x)
purchases or acquisitions of shares of Company Common Stock in connection with
the satisfaction by the Company of its obligations under any employee benefit
plans or the satisfaction by the Company of its obligations pursuant to any
contract or security requiring the Company to purchase shares of Company Common
Stock, (y) as a result of a reclassification of the Company's capital stock or
the exchange or conversion of one class or series of the Company's capital stock

(other than pursuant to the Guarantee).

                  (b) The Company also covenants and agrees (i) that it shall
directly or indirectly maintain 100% ownership of the Common Securities of the
Trust; provided, however, that any permitted successor of the Company hereunder
may succeed to the Company's ownership of such Common Securities and (ii) that
it shall use its reasonable efforts, consistent with the terms and provisions of
the Trust Agreement, to cause the Trust (x) to remain a statutory business
trust, except in connection with the distribution of the Convertible Debentures
to the holders of Trust Securities in liquidation of the Trust, the redemption
of all of the Trust Securities of the Trust, or certain mergers, consolida tions
or amalgamations, each as permitted by the Trust Agreement, and (y) to otherwise
continue to be classified as a grantor trust for United States Federal income
tax purposes.

SECTION 2006.              Payment of Expenses of the Trust.

                  In connection with the offering, sale and issuance of the

</TABLE>

If the Company has deferred interest payments, all unpaid interest must be paid
in cash prior to redemption. Any redemption pursuant to this Section 1101 shall
be made pursuant to the provisions of Sections 1103 through 1108 hereof.

         (b) If a partial redemption of the Convertible Debentures would result
in the delisting of the Preferred Securities issued by the Trust from any
national securities exchange or other organization on which the Preferred
Securities are listed, the Company shall not be permitted to effect such partial
redemption and may only redeem the Convertible Debentures in whole.

SECTION 2202. Tax Event Optional Redemption.

         If a Tax Event has occurred and is continuing and:

         (a) the Company has received a Redemption Tax Opinion; or

then, notwithstanding Section 1101(a) but subject to Section 1101(b), the
Company shall have the right upon not less than 30 days nor more than 60 days
notice to the Holders of the Convertible Debentures to redeem the Convertible
Debentures in whole (but not in part) for cash at a redemption price equal to
100% of the principal amount of the Convertible Debentures plus accrued and
unpaid interest (including Additional Payments), if any, within 90 days
following the occurrence of such Tax Event (the "90-Day Period"); provided,
however, that if, at the time there is available to the Company or the Trust the
opportunity to eliminate within the 90-Day Period, the Tax Event by taking some
ministerial action ("Ministerial Action"), such as filing a form or making an
election, or pursuing some other similar reasonable measure which, in the sole
judgment of the Company, has or will cause no adverse effect on the Company, the
Trust or the Holders of the Trust Securities and will involve no material cost,
the Company or the Trust shall pursue such Ministerial Action or other measure
in lieu of redemption, and provided, further, that the Company shall have no
right to redeem the Convertible Debentures while the Trust is pursuing any
Ministerial Action or other similar measure pursuant to its obligations under
the Trust Agreement.

SECTION 2203. Applicability of Article.

         Redemption of Convertible Debentures at the election of the Company, as
permitted by Sections 1101 and 1102, shall be made in accordance with such
provision and this Article.

SECTION 2204. Election to Redeem; Notice to Trustee.

         The election of the Company to redeem Convertible Debentures pursuant
to Section 1101 or 1102 shall be evidenced by a Board Resolution. In case of any
redemption at the election of the Company, the Company shall, at least 45 days
and no more than 90 days prior to the Redemption Date fixed by the Company,
notify the Trustee in writing of such Redemption Date and of the principal
amount of Convertible Debentures to be redeemed and provide a copy of the notice
of redemption given to Holders of Convertible Debentures to be redeemed pursuant
to Section 1105.

SECTION 2205. Selection by Trustee of Convertible Debentures to Be Redeemed.

         If less than all the Convertible Debentures are to be redeemed (unless
such redemption affects only a single Convertible Debenture), the particular
Convertible Debentures to be redeemed shall be selected not more than 45 days
prior to the Redemption Date by the Trustee, from the Outstanding Convertible
Debentures 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 $25 or any integral multiple thereof) of the
principal amount of the Convertible Debentures.

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



                                     - 59 -
<PAGE>   68

         The provisions of the two preceding paragraphs shall not apply with
respect to any redemption affecting only a single Convertible Debenture, whether
such Convertible Debenture is to be redeemed in whole or in part. In the case of
any such redemption in part, the unredeemed portion of the principal amount of
the Convertible Debenture shall be in an authorized denomination (which shall
not be less than the minimum authorized denomination) for such Convertible
Debenture.

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

SECTION 2206. Notice of Redemption.

         Notice of redemption shall be given by first-class mail, postage
prepaid, mailed not less than 30 nor more than 60 days prior to the Redemption
Date, to each Holder of Convertible Debentures to be redeemed, at such Holder's
address appearing in the Security Register.

         All notices of redemption shall identify the Convertible Debentures to
be redeemed (including, if relevant, CUSIP number or ISIN) and shall state:

SECTION 2207. Deposit and Payment of Redemption Price.

         Prior to 10:00 a.m. (New York City time) on the Redemption Date, the

any right of the Holder of such Convertible Debenture or any Predecessor
Security to receive interest as provided in the last paragraph of Section 307)

Convertible Debenture for redemption in accordance with said notice, such
Convertible Debenture shall be paid by the Company at the Redemption Price,
together with accrued and unpaid interest (including Additional Payments, if
any) to the Redemption Date; provided, however, that installments of interest
whose Stated Maturity is on or prior to the Redemption Date shall be payable to
the Holders of such Convertible Debentures, or one or more Predecessor
Convertible Debentures, registered as such at 5:00 p.m. (New York City time) on
the relevant Record Dates according to the terms and the provisions of Section
307.

         If any Convertible Debenture called for redemption shall not be so paid

Business Days before any selection for redemption of Convertible Debentures and
ending at 5:00 p.m. (New York City time) on the earliest date in which the
relevant notice of redemption is deemed to have been given to all holders of
Convertible Debentures to be so redeemed and (ii) register the transfer of or
exchange any Convertible Debentures so selected for redemption, in whole or in
part, except for the unredeemed portion of any Convertible Debentures being
redeemed in part.

surrendered at a place of payment therefor (with, if the Company or the Trustee
so requires, 



                                     - 61 -

due endorsement by, or a written instrument of transfer in form satisfactory to
the Company 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 make available for delivery to the Holder of such
Convertible Debenture without service charge, a new Convertible Debenture or
Convertible Debentures, 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 Convertible Debenture so surrendered.

SECTION 2210. No Sinking Fund.

         The Convertible Debentures are not entitled to the benefit of any
sinking fund.

SECTION 2211. Mandatory Redemption.

         Upon (i) repayment at maturity or (ii) as a result of acceleration upon

                                  ARTICLE XXIV

                     Subordination of Convertible Debentures

SECTION 2401. Agreement to Subordinate.

         The Company covenants and agrees, and each Holder of Convertible
Debentures by such Holder's acceptance thereof likewise covenants and agrees,
that all Convertible Debentures shall be issued subject to the provisions of
this Article Twelve; and each Holder of a Convertible Debenture, whether upon
original issue or upon transfer or assignment thereof, accepts and agrees to be
bound by such provisions. The payment by the Company of the principal of,
premium, if any, and interest (including Additional Payments, if any) on all
Convertible Debentures issued hereunder shall, to the extent and in the manner
hereinafter set forth, be subordinated and junior in right of payment to the
prior payment in full of all existing and future Senior Indebtedness, whether
outstanding at the date of this Indenture or thereafter incurred; provided
however, that no provision of this Article Twelve shall prevent the occurrence
of any default or Event of Default hereunder.

SECTION 2402. Default on Senior Indebtedness.

         In the event and during the continuation of any default by the Company
in the payment of principal, premium, interest or any other payment due on any
Senior Indebtedness continuing beyond the period of grace, if any, specified in
the instrument evidencing such Senior Indebtedness, unless and until such
default shall have been cured or waived or shall have ceased to exist, and in
the event that the maturity of any Senior Indebtedness has been accelerated
because of a default, then no payment shall be made by the Company with respect
to the principal of (including redemption payments, if any), premium, if any, or
interest on the Convertible Debentures.

         In the event that, notwithstanding the foregoing, any payment shall be
received by the Trustee when such payment is prohibited by the preceding
paragraph of this Section 1202, such payment shall be held in trust for the
benefit of, and shall be paid over or delivered to, the holders of Senior
Indebtedness or their respective representatives, or to the trustee or trustees
under any indenture pursuant to which any of such Senior Indebtedness may have
been issued, as their respective interests may appear, but only to the extent
that the holders of the Senior Indebtedness (or their representative or
representatives or a trustee) notify the Trustee in writing within 90 days of
such payment of the amounts then due and owing on the Senior Indebtedness and
only the amounts specified in such notice to the Trustee shall be paid to the
holders of Senior Indebtedness.

SECTION 2403. Liquidation; Dissolution; Bankruptcy.

         Upon any payment by the Company or distribution of assets of the
Company of any kind or character, whether in cash, property or securities, to
creditors upon any



                                     - 63 -
<PAGE>   72

dissolution or winding up or liquidation or reorganization of the Company,
whether voluntary or involuntary, or in bankruptcy, insolvency, receivership or
other proceedings, all principal of, and premium, if any, and interest due or to
become due on, all Senior Indebtedness must be paid in full before any payment
is made on account of the principal (and premium, if any) or interest (including
Additional Payments, if any) on the Convertible Debentures; and upon any such
dissolution or winding up or liquidation or reorganization, any payment by the
Company, or distribution of assets of the Company of any kind or character,
whether in cash, property or securities, to which the Holders of the Convertible
Debentures or the Trustee would be entitled, except for the provisions of this
Article Twelve, shall be paid by the Company or by any receiver, trustee in
bankruptcy, liquidating trustee, agent or other Person making such payment or
distribution, or by the Holders of the Convertible Debentures or by the Trustee
under this Indenture if received by them or it, directly to the holders of
Senior Indebtedness (pro rata to such holders on the basis of the respective
amounts of Senior Indebtedness held by such holders, as calculated by the
Company) or their representative or representatives, or to the trustee or
trustees under any indenture pursuant to which any instruments evidencing such
Senior Indebtedness may have been issued, as their respective interests may
appear, to the extent necessary to pay such Senior Indebtedness in full, in
money or money's worth, after giving effect to any concurrent payment or
distribution to or for the holders of such Senior Indebtedness, before any
payment or distribution is made to the Holders of Convertible Debentures or to
the Trustee.

         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, prohibited by the foregoing, shall be received by the
Trustee or the Holders of the Convertible Debentures before all Senior
Indebtedness is paid in full, or provision is made for such payment in money in
accordance with its terms, such payment or distribution shall be held in trust
for the benefit of and shall be paid over or delivered to the holders of Senior
Indebtedness or their representative or representatives, or to the trustee or
trustees under any indenture pursuant to which any instruments evidencing such
Senior Indebtedness may have been issued, and their respective interests may
appear, as calculated by the Company, for application to the payment of all
Senior Indebtedness remaining unpaid to the extent necessary to pay such Senior
Indebtedness in full in money in accordance with its terms, after giving effect
to any concurrent payment or distribution to or for the holders of such Senior
Indebtedness.

         For purposes of this Article Twelve, the words, "cash, property or
securities" shall not be deemed to include shares of stock of the Company as
reorganized or readjusted, or securities of the Company or any other corporation
provided for by a plan of reorganization or readjustment, the payment of which
is subordinated at least to the extent provided in this Article Twelve with
respect to the Convertible Debentures to the payment of all Senior Indebtedness
which may at the time be outstanding; provided, that (i) such Senior
Indebtedness is assumed by the new corporation, if any, resulting from any such
reorganization or readjustment, and (ii) the rights of the holders of such
Senior Indebtedness are not, without the consent of such holders, altered by
such reorganization or readjustment.

The consolidation of the Company with, or the merger of the Company with or
into, another Person or the liquidation or dissolution of the Company following
the conveyance, transfer or lease of all or substantially all its properties and
assets on a consolidated basis to another Person upon the terms and conditions
provided for in Article Eight hereof shall not be deemed a dissolution, winding
up, liquidation or reorganization for the purposes of this Section 1203 if such
other Person shall, as a part of such consolidation, merger, conveyance,
transfer or lease, comply with the conditions stated in Article Eight hereof.
Nothing in Section 1202 or in this Section 1203 shall apply to claims of, or
payments to, the Trustee under or pursuant to Section 607 hereof.

SECTION 2404. Subrogation.

         Subject to the payment in full of all Senior Indebtedness, the rights
of the Holders of the Convertible Debentures shall be subrogated to the rights
of the holders of such Senior Indebtedness to receive payments or distributions
of cash, property or securities of the Company, as the case may be, applicable
to such Senior Indebtedness until the principal of (and premium, if any,) and
interest (including Additional Payments, if any) on the Convertible Debentures
shall be paid in full; and, for the purposes of such subrogation, no payments or
distributions to the holders of such Senior Indebtedness of any cash, property
or securities to which the Holders of the Convertible Debentures or the Trustee
would be entitled except for the provisions of this Article Twelve, and no
payment over pursuant to the provisions of this Article Twelve, to or for the
benefit of the holders of such Senior Indebtedness by Holders of the Convertible
Debentures or the Trustee, shall, as between the Company, its creditors other
than holders of Senior Indebtedness, and the Holders of the Convertible
Debentures, be deemed to be a payment by the Company to or on account of such
Senior Indebtedness. It is understood that the provisions of this Article Twelve
are and are intended solely for the purposes of defining the relative rights of
the Holders of the Convertible Debentures, on the one hand, and the holders of
such Senior Indebtedness on the other hand.

         Nothing contained in this Article Twelve or elsewhere in this Indenture
or in the Convertible Debentures is intended to or shall impair, as between the
Company, its creditors other than the holders of Senior Indebtedness, and the
Holders of the Convertible Debentures, the obligation of the Company, which is
absolute and unconditional, to pay to the Holders of the Convertible Debentures
the principal of (and premium, if any) and interest (including Additional
Payments, if any) on the Convertible Debentures as and when the same shall
become due and payable in accordance with their terms, or is intended to or
shall affect the relative rights of the Holders of the Convertible Debentures
and creditors of the Company, as the case may be, other than the holders of
Senior Indebtedness, nor shall anything herein or therein prevent the Trustee or
the Holder of any Convertible Debenture from exercising all remedies otherwise
permitted by applicable law upon default under this Indenture, subject to the
rights, if any, under this Article Twelve of the holders of such Senior
Indebtedness in respect of cash, property or Convertible Debentures of the
Company, as the case may be, received upon the exercise of any such remedy.



                                     - 65 -
<PAGE>   74


         Upon any payment or distribution of assets of the Company referred to
in this Article Twelve, the Trustee, subject to the provisions of Section 603,
and the Holders of the Convertible Debentures, shall be entitled to rely upon
any order or decree made by any court of competent jurisdiction in which such
dissolution, winding up, liquidation or reorganization proceedings are pending,
or a certificate of the receiver, trustee in bankruptcy, liquidation trustee,
agent or other Person making such payment or distribution, delivered to the
Trustee or to the Holders of the Convertible Debentures, for the purposes of
ascertaining the Persons entitled to participate in such distribution, the
holders of the Senior Indebtedness and other indebtedness of the Company, as the
case may be, the amount thereof or payable thereon, the amount or amounts paid
or distributed thereon and all other facts pertinent thereto or to this Article
Twelve.

SECTION 2405. Trustee to Effectuate Subordination.

         Each Holder of Convertible Debentures by such Holder's acceptance
thereof authorizes and directs the Trustee on such Holder's behalf to take such
action as may be necessary or appropriate to effectuate the subordination
provided in this Article Twelve and appoints the Trustee as such Holder's
attorney-in-fact for any and all such purposes.

SECTION 2406. Notice by the Company.

         The Company shall give prompt written notice to a Responsible Officer
of the Trustee of any fact known to the Company which would prohibit the making
of any payment of monies to or by the Trustee in respect of the Convertible
Debentures pursuant to the provisions of this Article Twelve. Notwithstanding
the provisions of this Article Twelve or any other provision of this Indenture,
the Trustee shall not be charged with knowledge of the existence of any facts
which would prohibit the making of any payment of monies to or by the Trustee in
respect of the Convertible Debentures pursuant to the provision of this Article
Twelve, unless and until a Responsible Officer of the Trustee shall have
received written notice thereof at the Corporate Trust Office of the Trustee
from the Company or a holder or holders of Senior Indebtedness or from any
trustee therefor; and before the receipt of any such written notice, the
Trustee, subject to the provisions of Section 603 hereof, shall be entitled in
all respects to assume that no such facts exist; provided, however, that if the
Trustee shall not have received the notice provided for in this Section 1206 at
least two Business Days prior to the date upon which by the terms hereof any
money may become payable for any purpose (including, without limitation, the
payment of the principal of (and premium, if any) or interest (including
Additional Payments, if any) on any Convertible Debenture), then, anything
herein contained to the contrary notwithstanding, the Trustee shall have full
power and authority to receive such money and to apply the same to the purposes
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 to such
date.

         The Trustee, subject to the provisions of Section 603, shall be
entitled to rely on the delivery to it of a written notice by a Person
representing himself to be a holder of



                                     - 66 -
<PAGE>   75

Senior Indebtedness (or a trustee on behalf of such holder) to establish that
such notice has been given by a holder of such Senior Indebtedness or a trustee
on behalf of any such holder or holders. 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 Twelve, 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 right of such Person under this Article Twelve,
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 2407. Rights of the Trustee; Holders of Senior Indebtedness.

         The Trustee in its individual capacity shall be entitled to all the
rights set forth in this Article Twelve 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 deprive the Trustee of any of
its rights as such holder.

         With respect to the holders of Senior Indebtedness of the Company, the
Trustee undertakes to perform or to observe only such of its covenants and
obligations as are set forth in this Article Twelve, and no implied covenants or
obligations with respect to the holders of such Senior Indebtedness shall be
read into this Indenture against the Trustee. The Trustee shall not be deemed to
owe any fiduciary duty to the holders of such Senior Indebtedness and, subject
to the provisions of Section 603, the Trustee shall not be liable to any holder
of such Senior Indebtedness if it shall pay over or deliver to Holders of
Convertible Debentures, the Company or any other Person money or assets to which
any holder of such Senior Indebtedness shall be entitled by virtue of this
Article Twelve or otherwise. With respect to the holders of Senior Indebtedness,
the Trustee undertakes to perform or to observe only such of its covenants or
obligations as are specifically set forth in this Article Twelve and no implied
covenants or obligations with respect to holders of Senior Indebtedness shall be
read into this Indenture against the Trustee.

SECTION 2408. Subordination May Not Be Impaired.

         No right of any present or future holder of any Senior Indebtedness to
enforce subordination as herein provided shall at any time in any way be
prejudiced or impaired by any act or failure to act on the part of the Company
or by any act or failure to act, in good faith, by any such holder, or by any
noncompliance by the Company with the terms, provisions and covenants of this
Indenture, regardless of any knowledge thereof which any such holder may have or
otherwise be charged with.

         Without in any way limiting the generality of the foregoing paragraph,
the holders of Senior Indebtedness may, at any time and from time to time,
without the consent 



                                     - 67 -
<PAGE>   76

of or notice to the Trustee or the Holders of the Convertible Debentures,
without incurring responsibility to the holders of the Convertible Debentures
and without impairing or releasing the subordination provided in this Article
Twelve or the obligations hereunder of the Holders of the Convertible Debentures
to the holders of Senior Indebtedness, do any one or more of the following: (i)
change the manner, place or terms of payment or extend the time of payment of,
or renew or alter, such Senior Indebtedness, or otherwise amend or supplement in
any manner such Senior Indebtedness or any instrument evidencing the same or any
agreement under which such Senior Indebtedness is outstanding; (ii) sell,
exchange, release or otherwise deal with any property pledged, mortgaged or
otherwise securing such Senior Indebtedness; (iii) release any Person liable in
any manner for the collection of such Senior Indebtedness; and (iv) exercise or
refrain from exercising any rights against the Company and any other Person.

                                  ARTICLE XXVI

                      Conversion of Convertible Debentures

SECTION 2601. Conversion Rights.

         Subject to and upon compliance with the provisions of this Article, the
Convertible Debentures are convertible, at the option of the Holder, at any time
on or before 5:00 p.m. (New York City time) on the Business Day immediately
preceding the date of repayment of such Convertible Debentures, whether at
maturity or upon redemption (either at the option of the Company or pursuant to
a Tax Event), into fully paid and nonassessable shares of Company Common Stock
of the Company at an initial conversion rate of 0.4545 shares of Company Common
Stock for each $25 in aggregate principal amount of Convertible Debentures
(equal to a conversion price of $55.00 per share of Company Common Stock),
subject to adjustment as described in this Article Thirteen. A Holder of
Convertible Debentures may convert any portion of the principal amount of the
Convertible Debentures into that number of fully paid and nonassessable shares
of Company Common Stock (calculated as to each conversion to the nearest 1/100th
of a share) obtained by dividing the principal amount of the Convertible
Debentures to be converted by such conversion price. In case a Convertible
Debenture or portion thereof is called for redemption, such conversion right in
respect of the Convertible Debenture or portion so called shall expire at 5:00
p.m. (New York City time) on the Business Day immediately preceding the
corresponding Redemption Date, unless the Company defaults in making the payment
due upon redemption.

SECTION 2602. Conversion Procedures.

         (a) In order to convert all or a portion of the Convertible Debentures,
the Holder thereof shall deliver to the Conversion Agent an irrevocable Notice
of Conversion setting forth the principal amount of Convertible Debentures to be
converted, together with the name or names, if other than the Holder, in which
the shares of Company Common Stock should be issued upon conversion and, if such
Convertible Debentures are definitive Convertible Debentures, surrender to the
Conversion Agent the Convertible Debentures to be converted, duly endorsed or
assigned to the Company or in blank. In addition, a holder of Preferred
Securities may exercise its right under the Trust Agreement to convert such
Preferred Securities into Company Common Stock by delivering to the Conversion
Agent an irrevocable Notice of Conversion setting forth the information called
for by the preceding sentence and directing the Conversion Agent (i) to exchange
such Preferred Security for a portion of the Convertible Debentures held by the
Trust (at an exchange rate of $25 liquidation amount of Convertible Debentures
for each Preferred Security) and (ii) to immediately convert such Convertible
Debentures, on behalf of such holder, into Company Common Stock of the Company
pursuant to this Article Thirteen and, if such Preferred Securities are in
definitive form, surrendering such Preferred Securities, duly endorsed or
assigned to the Company or in blank. So long as any Preferred Securities are
outstanding, 



                                     - 69 -
<PAGE>   78

the Trust shall not convert any Convertible Debentures except pursuant to a
Notice of Conversion delivered to the Conversion Agent by a holder of Preferred
Securities.

         If a Notice of Conversion is delivered on or after the Regular Record
Date and prior to the subsequent Interest Payment Date, the Holder will be
entitled to receive the interest payable on the subsequent Interest Payment Date
on the portion of Convertible Debentures to be converted notwithstanding the
conversion thereof prior to such Interest Payment Date. Except as otherwise
provided in the immediately preceding sentence, in the case of any Convertible
Debenture which is converted, interest whose Stated Maturity is after the date
of conversion of such Convertible Debenture shall not be payable, and the
Company shall not make nor be required to make any other payment, adjustment or
allowance with respect to accrued but unpaid interest (including Additional
Payments, if any) on the Convertible Debentures being converted, which shall be
deemed to be paid in full. If any Convertible Debenture called for redemption is
converted, any money deposited with the Trustee or with any Paying Agent or so
segregated and held in trust for the redemption of such Convertible Debenture
shall (subject to any right of the Holder of such Convertible Debenture or any
Predecessor Security to receive interest as provided in the last paragraph of
Section 307 and this paragraph) be paid to the Company upon Company Request or,
if then held by the Company, shall be discharged from such trust.

         Each conversion shall be deemed to have been effected immediately prior
to 5:00 p.m. (New York City time) on the day on which the Notice of Conversion
was received (the "Conversion Date") by the Conversion Agent from the Holder or
from a holder of the Preferred Securities effecting a conversion thereof
pursuant to its conversion rights under the Trust Agreement, as the case may be.
The Person or Persons entitled to receive the Company Common Stock issuable upon
such conversion shall be treated for all purposes as the record holder or
holders of such Company Common Stock as of the Conversion Date. As promptly as
practicable on or after the Conversion Date, the Company shall issue and deliver
at the office of the Conversion Agent, unless otherwise directed by the Holder
in the Notice of Conversion, a certificate or certificates for the number of
full shares of Company Common Stock issuable upon such conversion, together with
the cash payment, if any, in lieu of any fraction of any share to the Person or
Persons entitled to receive the same. The Conversion Agent shall deliver such
certificate or certificates to such Person or Persons.

         (b) Subject to any right of the Holder of such Convertible Debenture or
any Predecessor Security to receive interest as provided in the last paragraph
of Section 307 and the second paragraph of Clause (a) of Section 1302, the
Company's delivery upon conversion of the fixed number of shares of Company
Common Stock into which the Convertible Debentures are convertible (together
with the cash payment, if any, in lieu of fractional shares) shall be deemed to
satisfy the Company's obligation to pay the principal amount at Maturity of the
portion of Convertible Debentures so converted and any unpaid interest
(including Additional Payments, if any) accrued on such Convertible Debentures
at the time of such conversion.



                                     - 70 -
<PAGE>   79

         (c) No fractional shares of Company Common Stock will be issued as a
result of conversion, but in lieu thereof, the Company shall pay to the
Conversion Agent a cash adjustment in an amount equal to the same fraction of
the last reported sale price of such fractional interest on the date on which
the Convertible Debentures or Preferred Securities, as the case may be, were
duly surrendered to the Conversion Agent for conversion, or, if such day is not
a Trading Day, on the next Trading Day, and the Conversion Agent in turn will
make such payment, if any, to the Holder of the Convertible Debentures or the
holder of the Preferred Securities so converted.

         (d) In the event of the conversion of any Convertible Debenture in part
only, a new Convertible Debenture or Convertible Debentures for the unconverted
portion thereof will be issued in the name of the Holder thereof upon the
cancellation thereof in accordance with Section 305.

         (e) In effecting the conversion transactions described in this Section,
the Conversion Agent is acting as agent of the holders of Preferred Securities
(in the exchange of Preferred Securities for Convertible Debentures) and as
agent of the Holders of Convertible Debentures (in the conversion of Convertible
Debentures into Company Common Stock), as the case may be, directing it to
effect such conversion transactions. The Conversion Agent is hereby authorized
(i) to exchange Convertible Debentures held by the Trust from time to time for
Preferred Securities in connection with the conversion of such Preferred
Securities in accordance with this Article Thirteen and (ii) to convert all or a
portion of the Convertible Debentures into Company Common Stock and thereupon to
deliver such shares of Company Common Stock in accordance with the provisions of
this Article Thirteen and to deliver to the Trust a new Convertible Debenture or
Convertible Debentures for any resulting unconverted principal amount.

         (f) Except as provided in Section 202, all shares of Company Common
Stock delivered upon any conversion of Restricted Securities shall bear a
Restrictive Securities Legend substantially in the form of the legend required
to be set forth on such Convertible Debentures and shall be subject to the
restrictions on transfer provided in such legend and in Section 314 hereof.
Neither the Trustee nor the Conversion Agent shall have any responsibility for
the inclusion or content of any such Restrictive Securities Legend on such
Company Common Stock; provided, however, that the Trustee or the Conversion
Agent shall have provided to the Company or to the Company's transfer agent for
such Company Common Stock, prior to or concurrently with a request to the
Company to deliver to such Conversion Agent certificates for such Company Common
Stock, written notice that the Convertible Debentures delivered for conversion
are Restricted Securities.

SECTION 2603. Conversion Price Adjustments.

         The conversion price shall be subject to adjustment (without
duplication) from time to time as follows:



                                     - 71 -
<PAGE>   80

         (a) In case the Company shall, while any of the Convertible Debentures
are outstanding, (i) pay a dividend or make a distribution with respect to its
Company Common Stock in shares of Company Common Stock, (ii) subdivide its
outstanding shares of Company Common Stock, (iii) combine its outstanding shares
of Company Common Stock into a smaller number of shares or (iv) issue by
reclassification of its shares of Company Common Stock any shares of capital
stock of the Company, the conversion price in effect immediately prior to such
action shall be adjusted so that the Holder of any Convertible Debentures
thereafter surrendered for conversion shall be entitled to receive the number of
shares of capital stock of the Company which he would have owned immediately
following such action had such Convertible Debentures been converted immediately
prior thereto. An adjustment made pursuant to this Section 1303(a) shall become
effective immediately after the record date in the case of a dividend or other
distribution and shall become effective immediately after the effective date in
case of a subdivision, combination or reclassification (or immediately after the
record date if a record date shall have been established for such event). If, as
a result of an adjustment made pursuant to this Section 1303(a), the Holder of
any Convertible Debenture thereafter surrendered for conversion shall become
entitled to receive shares of two or more classes or series of capital stock of
the Company, the Board of Directors (whose determination shall be conclusive and
shall be described in a Board Resolution filed with the Trustee) shall determine
the allocation of the adjusted conversion price between or among shares of such
classes or series of capital stock.

         (b) In case the Company shall, while any of the Convertible Debentures
are outstanding, issue rights or warrants to all holders of its Company Common
Stock entitling them (for a period expiring within 45 days after the record date
mentioned in this Section 1303(b)) to subscribe for or purchase shares of
Company Common Stock at a price per share less than the current market price per
share of Company Common Stock (as determined pursuant to 1303(f) below) on such
record date, the conversion price for the Convertible Debentures shall be
adjusted so that the same shall equal the price determined by multiplying the
conversion price in effect immediately prior to the date of issuance of such
rights or warrants by a fraction of which the numerator shall be the number of
shares of Company Common Stock outstanding on the date of issuance of such
rights or warrants plus the number of shares which the aggregate offering price
of the total number of shares so offered for subscription or purchase would
purchase at such current market price, and of which the denominator shall be the
number of shares of Company Common Stock outstanding on the date of issuance of
such rights or warrants plus the number of additional shares of Company Common
Stock offered for subscription or purchase. Such adjustment shall become
effective immediately after the record date for the determination of
stockholders entitled to receive such rights or warrants. For the purposes of
this subsection, the number of shares of Company Common Stock at any time
outstanding shall not include shares held in the treasury of the Company. The
Company shall not issue any rights or warrants in respect of shares of Company
Common Stock held in the treasury of the Company. In case any rights or warrants
referred to in this subsection in respect of which an adjustment shall have been
made shall expire unexercised within 45 days after the same shall have been
distributed or issued by the Company, the conversion price shall be readjusted
at the time of such 



                                     - 72 -
<PAGE>   81

expiration to the conversion price that would have been in effect if no
adjustment had been made on account of the distribution or issuance of such
expired rights or warrants.

         (c) Subject to the last sentence of this Section 1303(c), in case the
Company shall, by dividend or otherwise, distribute to all holders of its
Company Common Stock evidences of its indebtedness, shares of any class or
series of capital stock, cash or assets (including securities, but excluding any
rights or warrants referred to in Section 1303(b), any dividend or distribution
paid exclusively in cash and any dividend or distribution referred to in Section
1303(a)), the conversion price shall be reduced so that the same shall equal the
price determined by multiplying the conversion price in effect immediately prior
to the effectiveness of the conversion price reduction contemplated by this
Section 1303(c) by a fraction of which the numerator shall be the current market
price per share (determined as provided in Section 1303(f)) of the Company
Common Stock on the date fixed for the payment of such distribution (the
"Reference Date") less the fair market value (as determined in good faith by the
Board of Directors, whose determination shall be conclusive and described in a
resolution of the Board of Directors), on the Reference Date, of the portion of
the evidences of indebtedness, shares of capital stock, cash and assets so
distributed applicable to one share of Company Common Stock and the denominator
shall be such current market price per share of the Company Common Stock, such
reduction to become effective immediately prior to the opening of business on
the day following the Reference Date. In the event that such dividend or
distribution is not so paid or made, the conversion price shall again be
adjusted to be the conversion price which would then be in effect if such
dividend or distribution had not occurred. If the Board of Directors determines
the fair market value of any distribution for purposes of this Section 1303(c)
by reference to the actual or when issued trading market for any securities
comprising such distribution, it must in doing so consider the prices in such
market over the same period used in computing the current market price per share
of Company Common Stock (determined as provided in Section 1303(f)). For
purposes of this Section 1303(c), any dividend or distribution that includes
shares of Company Common Stock or rights or warrants to subscribe for or
purchase shares of Company Common Stock shall be deemed instead to be (1) a
dividend or distribution of the evidences of indebtedness, shares of capital
stock, cash or assets other than such shares of Company Common Stock or such
rights or warrants (making any conversion price reduction required by this
Section 1303(c)) immediately followed by (2) a dividend or distribution of such
shares of Company Common Stock or such rights or warrants (making any further
conversion price reduction required by Section 1303(a) or 1303(b)), except (A)
the Reference Date of such dividend or distribution as defined in this 1303(c)
shall be substituted as (a) "the record date in the case of a dividend or other
distribution," and (b) "the record date for the determination of stockholders
entitled to receive such rights or warrants" and (c) "the date fixed for such
determination" within the meaning of Sections 1303(a) and 1303(b) and (B) any
shares of Company Common Stock included in such dividend or distribution shall
not be deemed outstanding for purposes of computing any adjustment of the
conversion price in Section 1303(a).



                                     - 73 -
<PAGE>   82

         (d) In case the Company shall pay or make a dividend or other
distribution on its Company Common Stock exclusively in cash (excluding all
regular cash dividends, if the annualized amount thereof per share of Company
Common Stock does not exceed 20% of the current market price per share
determined as provided in Section 1303(f) of the Company Common Stock on the
Trading Day immediately preceding the date of declaration of such dividend), the
conversion price shall be reduced so that the same shall equal the price
determined by multiplying the conversion price in effect immediately prior to
the effectiveness of the conversion price reduction contemplated by this Section
1303(d) by a fraction of which the numerator shall be the current market price
per share (determined as provided in Section 1303(f)) of the Company Common
Stock on the date fixed for the payment of such distribution less the amount of
cash so distributed and not excluded as provided applicable to one share of
Company Common Stock and the denominator shall be such current market price per
share of the Company Common Stock, such reduction to become effective
immediately prior to the opening of business on the day following the date fixed
for the payment of such distribution; provided, however, that in the event the
portion of the cash so distributed applicable to one share of Company Common
Stock is equal to or greater than the current market price per share (as defined
in Section 1303(f)) of the Company Common Stock on the record date mentioned
above, in lieu of the foregoing adjustment, adequate provision shall be made so
that each Holder of shares of Convertible Debentures shall have the right to
receive upon conversion the amount of cash such Holder would have received had
such Holder converted each share of the Convertible Debentures immediately prior
to the record date for the distribution of the cash. In the event that such
dividend or distribution is not so paid or made, the conversion price shall
again be adjusted to be the conversion price which would then be in effect if
such record date had not been fixed.

         (e) In case a tender or exchange offer (other than an odd-lot offer)
made by the Company or any Subsidiary of the Company for all or any portion of
the Company's Company Common Stock shall expire and such tender or exchange
offer shall involve the payment by the Company or such Subsidiary of
consideration per share of Company Common Stock having a fair market value (as
determined in good faith by the Board of Directors, whose determination shall be
conclusive and described in a resolution of the Board of Directors) at the last
time (the "Expiration Time") tenders or exchanges may be made pursuant to such
tender or exchange offer (as it shall have been amended) that exceeds 110% of
the current market price per share (determined as provided in Section 1303(f))
of the Company Common Stock on the Trading Day next succeeding the Expiration
Time, the conversion price shall be reduced so that the same shall equal the
price determined by multiplying the conversion price in effect immediately prior
to the effectiveness of the conversion price reduction contemplated by this
Section 1303(e) by a fraction of which the numerator shall be the number of
shares of Company Common Stock outstanding (including any tendered or exchanged
shares) at the Expiration Time multiplied by the current market price per share
(determined as provided in Section 1303(f)) of the Company Common Stock on the
Trading Day next succeeding the Expiration Time and the denominator shall be the
sum of (x) the fair market value (determined as aforesaid) of the aggregate
consideration payable to stockholders based on the acceptance (up to any maximum
specified in the terms



                                     - 74 -
<PAGE>   83

of the tender or exchange offer) of all shares validly tendered or exchanged and
not withdrawn as of the Expiration Time (the shares deemed so accepted, up to
any such maximum, being referred to as the "Purchased Shares") and (y) the
product of the number of shares of Company Common Stock outstanding (less any
Purchased Shares) at the Expiration Time and the current market price per share
(determined as provided in Section 1303(f)) of the Company Common Stock on the
Trading Day next succeeding the Expiration Time, such reduction to become
effective immediately prior to the opening of business on the day following the
Expiration Time.

         (f) For the purpose of any computation under Section 1303(b), 1303(c),
1303(d) or 1303(e), the current market price per share of Company Common Stock
on any date in question shall be deemed to be the average of the daily Closing
Prices for the five consecutive Trading Days selected by the Company commencing
not more than 20 Trading Days before, and ending not later than, the earlier of
the day in question or, if applicable, the day before the "ex" date with respect
to the issuance or distribution requiring such computation; provided, however,
that if another event occurs that would require an adjustment pursuant to
Section 1303(a) through (e), inclusive, the Board of Directors may make such
adjustments to the Closing Prices during such five Trading Day period as it
deems appropriate to effectuate the intent of the adjustments in this Section
1303, in which case any such determination by the Board of Directors shall be
set forth in a Board Resolution and shall be conclusive. For purposes of this
paragraph, the term "ex" date, (i) when used with respect to any issuance or
distribution, means the first date on which the Company Common Stock trades
regular way on the New York Stock Exchange or on such successor securities
exchange as the Company Common Stock may be listed or in the relevant market
from which the Closing Prices were obtained without the right to receive such
issuance or distribution, and (ii) when used with respect to any tender or
exchange offer, means the first date on which the Company Common Stock trades
regular way on such securities exchange or in such market after the Expiration
Time of such offer.

         (g) The Company may make such reductions in the conversion price, in
addition to those required by Sections 1303 (a) through (e), as it considers to
be advisable to avoid or diminish any income tax to holders of Company Common
Stock or rights to purchase Company Common Stock resulting from any dividend or
distribution of stock (or rights to acquire stock) or from any event treated as
such for income tax purposes. The Company from time to time may reduce the
conversion price by any amount for any period of time if the period is at least
20 days, the reduction is irrevocable during the period, and the Board of
Directors of the Company shall have made a determination that such reduction
would be in the best interest of the Company, which determination shall be
conclusive. Whenever the conversion price is reduced pursuant to the preceding
sentence, the Company shall mail to holders of record of the Convertible
Debentures a notice of the reduction at least 15 days prior to the date the
reduced conversion price takes effect, and such notice shall state the reduced
conversion price and the period it will be in effect.



                                     - 75 -
<PAGE>   84

         (h) No adjustment in the conversion price shall be required unless such
adjustment would require an increase or decrease of at least 1% in the
conversion price; provided, however, that any adjustments which by reason of
this Section 1303(h) are not required to be made shall be carried forward and
taken into account in determining whether any subsequent adjustment shall be
required.

         (i) If any action would require adjustment of the conversion price
pursuant to more than one of the provisions described above, only one adjustment
shall be made and such adjustment shall be the amount of adjustment that has the
highest absolute value to the Holder of the Convertible Debentures.

SECTION 2604. Fundamental Change.

         (a) In the event that the Company is party to any transaction
(including, without limitation, a merger other than a merger that does not
result in a reclassification, conversion, exchange or cancellation of Company
Common Stock), consolidation, sale of all or substantially all of the assets of
the Company, recapitalization or reclassification of Company Common Stock (other
than a change in par value, or from par value to no par value, or from no par
value to par value or as a result of a subdivision or combination of Company
Common Stock) or any compulsory share exchange (each of the foregoing being
referred to as a "Transaction"), in each case, as a result of which shares of
Company Common Stock shall be converted into the right to receive, or shall be
exchanged for, (i) in the case of any Transaction other than a Transaction
involving a Common Stock Fundamental Change (and subject to funds being legally
available for such purpose under applicable law at the time of such conversion),
securities, cash or other property, each Preferred Security shall thereafter be
convertible into the kind and, in the case of a Transaction which does not
involve a Fundamental Change, amount of securities, cash and other property
receivable upon the consummation of such Transaction by a holder of that number
of shares of Company Common Stock into which a Preferred Security was
convertible immediately prior to such Transaction, or (ii) in the case of a
Transaction involving a Common Stock Fundamental Change, common stock, each
Preferred Security shall thereafter be convertible (in the manner described
therein) into common stock of the kind received by holders of Company Common
Stock (but in each case after giving effect to any adjustment discussed below
relating to a Fundamental Change if such Transaction constitutes a Fundamental
Change). The holders of Preferred Securities will have no voting rights with
respect to any Transaction.

         (b) If any Fundamental Change occurs, then the conversion price in
effect will be adjusted immediately after such Fundamental Change as described
below. In addition, in the event of a Common Stock Fundamental Change, each
Preferred Security shall be convertible solely into common stock of the kind
received by holders of Company Common Stock as a result of such Common Stock
Fundamental Change.



                                     - 76 -
<PAGE>   85

         (c) The conversion price in the case of any Transaction involving a
Fundamental Change will be adjusted immediately after such Fundamental Change:

                  (i)  in the case of a Non-Stock Fundamental Change, the
         conversion price of the Preferred Securities will thereupon become the
         lower of (A) the conversion price in effect immediately prior to such
         Non-Stock Fundamental Change, but after giving effect to any other
         prior adjustments effected pursuant to the preceding paragraphs, and
         (B) the greater of the Applicable Price or the then applicable
         Reference Market Price plus any then-accrued and unpaid distributions
         on one Preferred Security; and

                  (ii) in the case of a Common Stock Fundamental Change, the
         conversion price of the Preferred Securities in effect immediately
         prior to such Common Stock Fundamental Change, but after giving effect
         to any other prior adjustments effected pursuant to the preceding
         paragraphs, will thereupon be adjusted by multiplying such conversion
         price by a fraction of which the numerator will be the Purchaser Stock
         Price and the denominator will be the Applicable Price; provided,
         however, that in the event of a Common Stock Fundamental Change in
         which (A) 100% of the value of the consideration received by a holder
         of Company Common Stock is common stock of the successor, acquirer, or
         other third party (and cash, if any, is paid only with respect to any
         fractional interests in such common stock resulting from such Common
         Stock Fundamental Change) and (B) all Company Common Stock will be have
         been exchanged for, converted into, or acquired for common stock (and
         cash with respect to fractional interests) of the successor, acquirer,
         or other third party, the conversion price of the Preferred Securities
         in effect immediately prior to such Common Stock Fundamental Change
         will thereupon be adjusted by multiplying such conversion price by a
         fraction of which the numerator will be one and the denominator will be
         the number of shares of common stock of the successor, acquirer, or
         other third party received by a holder of one share of Company Common
         Stock as a result of such Common Stock Fundamental Change.

         The Company or the Person formed by such consolidation or resulting
from such merger or which acquired such assets or which acquires the Company's
shares, as the case may be, shall make provision in its certificate or articles
of incorporation or other constituent document to establish such right. Such
certificate or articles of incorporation or other constituent document shall
provide for adjustments which, for events subsequent to the effective date of
such certificate or articles of incorporation or other constituent document,
shall be as nearly equivalent as may be practicable to the adjustments provided
for in this Article Thirteen. The above provisions shall similarly apply to
successive transactions of the foregoing type.

distribution) on its Company Common Stock, other than (A) a dividend payable in
shares of Company Common Stock or (B) a dividend payable in cash that would not
require an adjustment pursuant to Section 1303(c) or 1303(d), or (ii) authorize
a tender or exchange offer that would require an adjustment pursuant to Section
1303(e);

         (b) the Company shall authorize the granting to all holders of Company
Common Stock of rights or warrants to subscribe for or purchase any shares of
stock of any class or series or of any other rights or warrants;

of any reclassification of Company Common Stock (other than a subdivision or
combination of the outstanding Company Common Stock, or a change in par value,
or from par value to no par value, or from no par value to par value), or of any
consolidation or merger to which the Company is a party and for which approval
of any stockholders of the Company shall be required, or of the sale or transfer
of all or substantially all of the assets of the Company or of any compulsory
share exchange whereby the Company Common Stock is converted into other
securities, cash or other property; or

         (c) of the voluntary or involuntary dissolution, liquidation or winding

or effective date hereinafter specified, a notice stating (x) the date on which
a record (if any) is to be taken for the purpose of such dividend, distribution,
rights or warrants or, if a record is not to be taken, the date as of which the
holders of Company Common Stock of record to be entitled to such dividend,
distribution, rights or warrants are to be determined or (y) the date on which
such reclassification, consolidation, merger, sale, transfer, share exchange,
dissolution, liquidation or winding up is expected to become effective, and the
date as of which it is expected that holders of Company Common Stock of record
shall be entitled to exchange their shares of Company Common Stock for
securities, cash or other property deliverable upon such reclassification,
consolidation, merger, sale, transfer, share exchange, dissolution, liquidation
or winding up (but no failure to mail such notice or any defect therein or in
the mailing thereof shall affect the validity of the corporate action required
to be specified in such notice).

SECTION 2607. Certain Defined Terms.

         The following definitions shall apply to terms used in this Article
Thirteen:

         (a) "Closing Price" of any Company Common Stock on any day shall mean
the reported last sale price on such day or in case no sale takes place on such
day, the average of the reported closing bid and asked prices in each case on
the NYSE Consolidated Transactions Tape or, if the stock is not listed or
admitted to trading on the NYSE, on the principal national securities exchange
on which such stock is listed or admitted to trading or, if not listed or

rights to purchase such shares pursuant to any employee benefit plan or program
of the Company or pursuant to any option, warrant, right or exercisable,
exchangeable or convertible security outstanding as of the date the Convertible
Debentures were first issued, shall not be deemed to constitute an issuance of
Company Common Stock or exercisable, exchangeable or convertible securities by
the Company to which any of the adjustment provisions described above applies.
There shall also be no adjustment of the conversion price in case of the
issuance of any stock (or securities convertible into or exchangeable for stock)

                                     - 79 -
<PAGE>   88

SECTION 2609. Certain Additional Rights.

         In case the Company shall, by dividend or otherwise, declare or make a
distribution on its Company Common Stock referred to in Section 1303(c) or
1303(d) (including, without limitation, dividends or distributions referred to
in the last sentence of Section 1303(c)), the Holder of the Convertible
Debentures, upon the conversion thereof subsequent to 5:00 p.m. (New York City
time) on the date fixed for the determination of stockholders entitled to
receive such distribution and prior to the effectiveness of the conversion price
adjustment in respect of such distribution, shall also be entitled to receive
for each share of Company Common Stock into which the Convertible Debentures are
converted, the portion of the shares of Company Common Stock, rights, warrants,
evidences of indebtedness, shares of capital stock, cash and assets so
distributed applicable to one share of Company Common Stock; provided, however,
that, at the election of the Company (whose election shall be evidenced by a
resolution of the Board of Directors) with respect to all Holders so converting,
the Company may, in lieu of distributing to such Holder any portion of such
distribution not consisting of cash or securities of the Company, pay such
Holder an amount in cash equal to the fair market value thereof (as determined
in good faith by the Board of Directors, whose determination shall be conclusive
and described in a resolution of the Board of Directors). If any conversion of
Convertible Debentures described in the immediately preceding sentence occurs
prior to the payment date for a distribution to holders of Company Common Stock
which the Holder of Convertible Debentures so converted is entitled to receive
in accordance with the immediately preceding sentence, the Company may elect
(such election to be evidenced by a resolution of the Board of Directors) to
distribute to such Holder a due bill for the shares of Company Common Stock,
rights, warrants, evidences of indebtedness, shares of capital stock, cash or
assets to which such Holder is so entitled, provided, that such due bill (i)
meets any applicable requirements of the principal national securities exchange
or other market on which the Company Common Stock is then traded and (ii)
requires payment or delivery of such shares of Company Common Stock, rights,
warrants, evidences of indebtedness, shares of capital stock, cash or assets no
later than the date of payment or delivery thereof to holders of shares of
Company Common Stock receiving such distribution.

SECTION 2610. Restrictions on Company Common Stock Issuable Upon Conversion.

         (a) Shares of Company Common Stock to be issued upon conversion of a
Convertible Debenture in respect of Restricted Preferred Securities shall bear
such restrictive legends as the Company may provide in accordance with
applicable law.

         (b) If shares of Company Common Stock to be issued upon conversion of a
Convertible Debenture in respect of Restricted Preferred Securities are to be
registered in a name other than that of the Holder of such Preferred Security,
then the Person in whose name such shares of Company Common Stock are to be
registered must deliver to the Conversion Agent a certificate satisfactory to
the Company and signed by such Person, as to compliance with the restrictions on
transfer applicable to such Preferred Security. Neither the Trustee



                                     - 80 -
<PAGE>   89

nor any Conversion Agent or Registrar shall be required to register in a name
other than that of the Holder shares of Company Common Stock issued upon
conversion of any such Convertible Debenture in respect of such Preferred
Securities not so accompanied by a properly completed certificate.

SECTION 2611. Trustee Not Responsible for Determining Conversion Price or
              Adjustments.

         Neither the Trustee nor any Conversion Agent shall at any time be under
any duty or responsibility to any Holder of any Convertible Debenture to
determine whether any facts exist which may require any adjustment of the

Company Common Stock or stock certificates or other securities or property upon
the surrender of any Convertible Debenture for the purpose of conversion, or,
except as expressly herein provided, to comply with any of the covenants of the

                   [FORM OF REVERSE OF CONVERTIBLE DEBENTURE]

         This Convertible Debenture is one of a duly authorized issue of
securities of the Company designated as its 5 1/4% Convertible Subordinated
Debenture Due 2028 (herein called the "Convertible Debentures"), in aggregate
principal amount of $103,092,775 (or up to $113,402,050 if the over-allotment
option is exercised by the Trust in accordance with the terms and provisions of
the Purchase Agreement), issued and to be issued under an Indenture, dated as of
March 18, 1998 (herein called the "Indenture"), between the Company and Chase
Bank of Texas, National Association, as Trustee (herein called the "Trustee",
which term includes any successor trustee under the Indenture), to which
Indenture and all indentures supplemental thereto reference is hereby made for a
statement of the respective rights, limitations of rights, duties and immunities
thereunder of the Trustee, the Company and the Holders of the Convertible
Debentures, and of the terms upon which the Convertible Debentures are, and are
to be, authenticated and delivered. The terms of the Convertible Debentures
include those stated in the Indenture and those made part of the Indenture by
the Trust Indenture Act of 1939 (15 U.S.C. ss. 77aaa-77bbbb) ("TIA") as in
effect on the date of the Indenture. The Convertible Debentures are subject to,
and qualified by, all such terms, certain of which are summarized hereon, and
holders are referred to the Indenture and the TIA for a statement of such terms.
No reference herein to the Indenture and no provision of this Convertible
Debenture or of the Indenture shall alter or impair the obligation of the
Company, which is absolute and unconditional, to pay the principal of and
interest on this Convertible Debenture at the times, place and rate, and in the
coin or currency, herein prescribed or to convert this Convertible Debenture as
provided in the Indenture. All terms used in this Convertible Debenture which
are defined in the Indenture shall have the meanings assigned to them in the
Indenture. The Company will furnish to any Holder upon written request and
without charge a copy of the Indenture.

         (1) Interest. The Convertible Debentures shall bear interest at the
rate of 5 1/4% per annum, from March 13, 1998 or from the most recent Interest
Payment Date to which interest has been paid or duly provided for, as the case
may be, payable quarterly (subject to deferral as set forth herein), in arrears,
on January 1, April 1, July 1 and October 1 (each an "Interest Payment Date") of
each year, commencing July 1, 1998, until the principal thereof is paid or made
available for payment, and they shall be paid to the Person in whose name the
Convertible Debenture is registered at 5:00 p.m. (New York City time) on the
regular record date for such interest installment, which shall be the March 15,
June 15, September 15 and December 15 next preceding such Interest Payment Date
(the "Regular Record Date"). Interest will compound quarterly and will accrue at
the rate of 5 1/4% per annum on any interest installment in arrears for more
than one quarter or during an extension of an interest payment period as set
forth below.


                                     - 6 -
<PAGE>   100

         The amount of interest payable for any period will be computed on the
basis of a 360-day year of twelve 30-day months. Except as provided in the
following sentence, the amount of interest payable for any period shorter than a
full quarterly period for which interest in computed, will be computed on the
basis of the actual number of days elapsed per 90-day quarter. In the event that
any date on which interest is payable on the Convertible Debentures is not a
Business Day, then payment of interest payable on such date will be made on the
next succeeding day which is a Business Day (and without any interest or other
payment in respect of any such delay), except that, if such Business Day is in
the next succeeding calendar year, such payment shall be made on the immediately
preceding Business Day, in each case with the same force and effect as if made
on such date.

         If at any time while the Property Trustee is the Holder of any
Convertible Debentures, the Trust or the Property Trustee is required to pay any
taxes, duties, assessments or governmental charges of whatever nature (other
than withholding taxes) imposed by the United States, or any other taxing
authority, then, in any such case, the Company shall pay as additional interest
("Additional Interest") on the Convertible Debentures held by the Property
Trustee, such amounts as shall be required so that the net amounts received and
retained by the Trust and the Property Trustee after paying any such taxes,
duties, assessments or other governmental charges will be not less than the
amounts the Trust and the Property Trustee would have received had no such
taxes, duties, assessments or other governmental charges been imposed.

         The principal of and interest on the Convertible Debentures shall be
payable [insert, if global security is issued - to the Depositary Trust Company
or its nominee] [insert, if securities in definitive form are issued - at the
corporate office of the Indenture Trustee in the City of New York or at the
office or agency of the Paying Agent in the United States maintained for such
purpose] in such coin or currency of the United States of America as at the time
of payment is legal tender for payment of public and private debts; provided,
however, that at the option of the Company payment of interest may be made by
(i) check mailed to the address of the Person entitled thereto as such address
shall appear in the Security Register, or (ii) by wire transfer to an account
maintained by the Person entitled thereto as specified in the Securities
Register, provided that proper transfer instructions have been received by the
Regular Record Date.

         (2) Option to Extend Interest Payment Period. The Company shall have
the right at any time during the term of the Convertible Debentures to defer
interest payments (including Additional Payments) from time to time by extending
the interest payment period for successive periods (each, an "Extension Period")
not exceeding 20 consecutive quarters for each such period; provided, no
Extension Period may extend



                                     - 7 -
<PAGE>   101

beyond the maturity date of the Convertible Debentures. At the end of each
Extension Period, the Company shall pay all interest then accrued and unpaid
(including Additional Interest) together with interest thereon compounded
quarterly at the rate specified for the Convertible Debentures to the extent
permitted by applicable law ("Compounded Interest"); provided, that during any
Extension Period, the Company shall (i) not declare or pay dividends on, or make
a distribution with respect to, or redeem or purchase or acquire, or make a
liquidation payment with respect to, any of its capital stock (other than (A)
purchases or acquisitions of shares of Company Common Stock in connection with
the satisfaction by the Company of its obligations under any employee benefit
plans or the satisfaction by the Company of its obligations pursuant to any
contract or security requiring the Company to purchase shares of Company Common
Stock, (B) as a result of a reclassification of the Company's capital stock or
the exchange or conversion of one class or series of the Company's capital stock
for another class or series of the Company's capital stock or (C) the purchase
of fractional interests in shares of the Company's capital stock pursuant to the
conversion or exchange provisions of such capital stock or the security being
converted or exchanged) or make any guarantee payments with respect to the
foregoing, (ii) not make any payment of interest, principal or premium, if any,
on or repay, repurchase or redeem any debt securities (including guarantees)
issued by the Company that rank pari passu with or junior to the Convertible
Debentures (except by conversion into or exchange for shares of its capital
stock) and (iii) not make any guarantee payments with respect to the foregoing
(other than pursuant to the Guarantee). Prior to the termination of any such
Extension Period, the Company may further extend such Extension Period;
provided, that such Extension Period, together with all such previous and
further extensions thereof, may not exceed 20 consecutive quarters or extend
beyond the maturity date of the Convertible Debentures. Upon the termination of
any Extension Period and the payment of all amounts then due, the Company may
commence a new Extension Period, subject to the above requirements. No interest
during an Extension Period shall be due and payable. Notwithstanding anything to
the contrary, the Company shall not have the right at any time to defer any
Additional Interest, including by extending the interest payment period.

         If the Property Trustee is the sole Holder of the Convertible
Debentures at the time the Company selects an Extension Period, the Company
shall give written notice to the Administrative Trustees, the Property Trustee
and the Trustee of its selection of such Extension Period at least one Business
Day prior to the earlier of (i) the date the distributions on the Preferred
Securities are payable or (ii) if the Preferred Securities are listed on the New
York Stock Exchange or other stock exchange or quotation system, the date the
Trust is required to give notice to the New York Stock Exchange or other
applicable self-regulatory organization or to holders of the Preferred
Securities of the record date or the date such distributions are payable, but in
any event not less than 10 Business Days prior to such record date.



                                     - 8 -
<PAGE>   102

         If the Property Trustee is not the sole holder of the Convertible
Debentures at the time the Company selects an Extension Period, the Company
shall give the Holders of the Convertible Debentures and the Trustee written
notice of its selection of such Extension Period at least 10 Business Days prior
to the earlier of (i) the next succeeding Interest Payment Date or (ii) if the
Preferred Securities are listed on the New York Stock Exchange or other stock
exchange or quotation system, the date the Company is required to give notice to
the New York Stock Exchange or other applicable self-regulatory organization or
to holders of the Convertible Debentures on the record or payment date of such
related interest payment, but in any event not less than two Business Days prior
to such record date.

         The quarter in which any notice is given pursuant to paragraphs second
and third of this Section 2 shall be counted as one of the 20 quarters permitted
in the maximum Extension Period permitted under paragraph one of this Section 2.

         (3) Paying Agent and Security Registrar. The Trustee will act as Paying
Agent, Security Registrar and Conversion Agent. The Company may change any
Paying Agent, Security Registrar, co-registrar or Conversion Agent without prior
notice. The Company or any of its Affiliates may act in any such capacity.

         (4) Redemption. The Company shall have the right to redeem the
Convertible Debentures, in whole or in part, at any time or from time to time
after April 3, 2001 upon not less than 30 nor more than 60 days' notice, at the
optional redemption prices (expressed as a percentage of the principal amount of
Convertible Debentures to be redeemed) shown below, plus any accrued and unpaid
interest (including Additional Payments, if any) to the Redemption Date, if
redeemed during the 12-month period beginning April 3:

          2005 and thereafter ...................     100.00%
</TABLE>

         If the Company has deferred interest payments, all unpaid interest must
be paid in cash prior to redemption. Any redemption pursuant to this Section
1101 shall be made pursuant to the provisions of Sections 1103 through 1108
hereof.



                                     - 9 -
<PAGE>   103

         The Convertible Debentures are subject to redemption in whole (but not
in part), at any time within 90 days, if a Tax Event (as defined in the Trust
Agreement) shall occur and be continuing, at a redemption price equal to 100% of
the principal amount thereof plus accrued but unpaid interest (including
Additional Payments, if any) to the Redemption Date. On and after the Redemption
Date, interest ceases to accrue on the Convertible Debentures or portions of
them called for redemption.

         Notice of redemption shall be given by first-class mail, postage
prepaid, mailed not less than 30 nor more than 60 days prior to the Redemption
Date, to each Holder of Convertible Debentures to be redeemed, at such Holder's
address appearing in the Security Register. The Convertible Debentures in
denominations larger than $25 may be redeemed in part but only in integral
multiples of $25. In the event of a redemption of less than all of the
Convertible Debentures, the Convertible Debentures will be chosen for redemption
by the Trustee in accordance with the Indenture.

         If this Convertible Debenture is redeemed subsequent to a Regular
Record Date with respect to any Interest Payment Date specified above and on or
prior to such Interest Payment Date, then any accrued interest will be paid to
the person in whose name this Convertible Debenture is registered at the close
of business on such record date.

         (5) Sinking Fund. The Convertible Debentures are not entitled to the
benefit of any sinking fund.

         (6) Subordination. The payment of the principal of, premium, if any,
and interest (including Additional Payments, if any) on all Convertible
Debentures is subordinated and junior in right of payment to the prior payment
in full of all existing and future Senior Indebtedness, whether outstanding at
the date of this Indenture or thereafter incurred. Each holder, by accepting a
Convertible Debenture, agrees to such subordination and authorizes and directs
the Trustee on its behalf to take such action as may be necessary or appropriate
to effectuate the subordination so provided and appoints the Trustee as its
attorney-in-fact for such purpose.

         "Senior Indebtedness" means in respect of the Company (i) the
principal, premium, if any, and interest in respect of (A) indebtedness of such
obligor for money borrowed and (B) indebtedness evidenced by securities,
debentures, bonds or other similar instruments issued by such obligor, (ii) all
capital lease obligations of such obligor, (iii) all obligations of such obligor
issued or assumed as the deferred purchase price of property, all conditional
sale obligations of such obligor and all obligations of such obligor under any
title retention agreement (but excluding trade accounts payable arising in the
ordinary course of business), (iv) all obligations of such obligor for the
reimbursement of any letter 



                                     - 10 -
<PAGE>   104

of credit, banker's acceptance, security purchase facility or similar credit
transaction, (v) all obligations of the type referred to in clauses (i) through
(iv) above of other Persons for the payment of which such obligor is responsible
or liable as obligor, guarantor or otherwise, and (vi) all obligations of the
type referred to in clauses (i) through (v) above of other Persons secured by
any lien on any property or asset of such obligor (whether or not such
obligation is assumed by such obligor), except for (1) any such indebtedness
that is by its terms subordinated to or pari passu with the Convertible
Debentures and (2) any indebtedness between or among such obligor or its
affiliates, including all other debt securities and guarantees in respect of
those debt securities issued to any other trust, or a trustee of such trust,
partnership, or other entity affiliated with the Company that is, directly or
indirectly, a financing vehicle of the Company (a "Financing Entity") in
connection with the issuance by such Financing Entity of preferred securities or
other securities which rank pari passu with, or junior to, the Preferred
Convertible Debentures. Such Senior Indebtedness shall continue to be Senior
Indebtedness and entitled to the benefits of the subordination provisions
irrespective of any amendment, modification or waiver of any term of such Senior
Indebtedness.

         (7) Conversion. The Holder of any Convertible Debenture has the right,
exercisable at any time on or before 5:00 p.m. (New York City time) on the
Business Day immediately preceding the date of repayment of such Convertible
Debentures, whether at maturity or upon redemption (either at the option of the
Company or pursuant to a Tax Event), to convert the principal amount thereof (or
any portion thereof that is an integral multiple of $25) into fully paid and
nonassessable shares of Company Common Stock of the Company at an initial
conversion rate of 0.4545 shares of Company Common Stock for each $25 in
aggregate principal amount of Convertible Debentures (equal to a conversion
price of $55.00 per share of Company Common Stock), subject to adjustment under
certain circumstances as set forth in Section 1303. The number of shares
issuable upon conversion of a Convertible Debenture is determined by dividing
the principal amount of the Convertible Debenture converted by the conversion
price in effect on the Conversion Date. No fractional shares will be issued upon
conversion but a cash adjustment will be made for any fractional interest. The
outstanding principal amount of any Convertible Debenture shall be reduced by
the portion of the principal amount thereof converted into shares of Company
Common Stock.

         To convert a Convertible Debenture, a Holder must (i) complete and sign
a conversion notice substantially in the form attached hereto, (ii) surrender
the Convertible Debenture to a Conversion Agent, (iii) furnish appropriate
endorsements or transfer documents if required by the Security Registrar or
Conversion Agent and (iv) pay any transfer or similar tax, if required. If a
Notice of Conversion is delivered on or after the Regular Record Date and prior
to the subsequent Interest Payment Date, the Holder will be



                                     - 11 -
<PAGE>   105

entitled to receive the interest payable on the subsequent Interest Payment Date
on the portion of Convertible Debentures to be converted notwithstanding the
conversion thereof prior to such Interest Payment Date. Except as otherwise
provided in the immediately preceding sentence, in the case of any Convertible
Debenture which is converted, interest whose Stated Maturity is after the date
of conversion of such Convertible Debenture shall not be payable, and the
Company shall not make nor be required to make any other payment, adjustment or
allowance with respect to accrued but unpaid interest (including Additional
Payments, if any) on the Convertible Debentures being converted, which shall be
deemed to be paid in full. If any Convertible Debenture called for redemption is
converted, any money deposited with the Trustee or with any Paying Agent or so
segregated and held in trust for the redemption of such Convertible Debenture
shall (subject to any right of the Holder of such Convertible Debenture or any
Predecessor Security to receive interest as provided in the last paragraph of
Section 307 and this paragraph) be paid to the Company upon Company Request or,
if then held by the Company, shall be discharged from such trust.

         (8) Registration Rights. The holders of the Preferred Securities, the
Convertible Debentures issuable in respect of the Preferred Securities, the
shares of Company Common Stock issuable upon conversion of the Preferred
Securities and the Convertible Debentures, and the Guarantee (collectively, the
"Registrable Securities") are entitled to the benefits of a Registration Rights
Agreement, dated as of March 18, 1998, among Central Parking Finance Trust, the
Company and the Initial Purchasers (the "Registration Rights Agreement").
Pursuant to the Registration Rights Agreement, the Company has agreed for the
benefit of the holders of Registrable Securities that (i) it will, at its cost,
use its best efforts within 60 days after the date of original issuance of the
Registrable Securities, to file a shelf registration statement (the "Shelf
Registration Statement") with the Commission with respect to the resales of the
Registrable Securities, (ii) it will use its best efforts to cause such Shelf
Registration Statement to be declared effective by the Commission within 150
days after the date of issuance of the Registrable Securities and (iii) it will
use its best efforts to maintain such Shelf Registration Statement continuously
effective under the Securities Act until two years after the date of original
issuance of the Preferred Securities (or such earlier date as the holders of
Registrable Securities are able to sell all Registrable Securities immediately
without restriction, whether pursuant to Rule 144(k) under the Securities Act or
any successor rule thereto or otherwise) (the "Effectiveness Period"). The Trust
and the Company will be permitted to suspend the use of the prospectus (which is
a part of the Shelf Registration Statement) in connection with sales of
Registrable Securities by holders during certain periods of time under certain
circumstances relating to pending corporate developments relating to the Company
and public filings with the Commission and similar events.



                                     - 12 -
<PAGE>   106

         If (i) on or prior to 60 days following the date of original issuance
         of the Registrable Securities, a Shelf Registration Statement has not
         been filed with the Commission, (ii) on or prior to the 150th day
         following the original issuance of the Registrable Securities, such
         Shelf Registration Statement has not been declared effective, or (iii)
         the Company or the Trust has not filed an amendment as set forth in
         Sections 2(b)(ii) and 3(j) of the Registration Rights Agreement (each
         such event a "Registration Default"), additional interest ("Liquidated
         Damages") will accrue on the Convertible Debentures and, accordingly,
         additional distributions will accrue on the Preferred Securities, from
         and including the day following such Registration Default until such
         time as such Shelf Registration Statement is filed or such Shelf
         Registration Statement is declared effective, as the case may be.
         Liquidated Damages will be paid quarterly in arrears (subject to the
         Company's ability to defer payment of Liquidated Damages during any
         Extension Period), with the first quarterly payment due on the first
         Interest Payment Date following the date on which such Liquidated
         Damages begin to accrue, and will accrue at a rate per annum equal to
         an additional 0.25% of the principal amount or liquidation amount, as
         applicable, to and including the 60th day following such Registration
         Default and 0.50% thereof from and after the 61st day following such
         Registration Default. In the event that during the Effectiveness Period
         the Shelf Registration Statement ceases to be effective for more than
         90 consecutive days or any 120 days, whether or not consecutive, during
         any 12-month period then the interest rate borne by the Debentures and
         the distribution rate borne by the Preferred Securities will each
         increase by an additional 0.50% per annum from such 91st or 121st day,
         as applicable, of the applicable 12-month period such Shelf
         Registration Statement ceases to be effective until the earlier of such
         time as (i) the Shelf Registration Statement again becomes effective or
         (ii) the Effectiveness Period expires.

         (9) Registration, Transfer, Exchange and Denominations. As provided in
the Indenture and subject to certain limitations therein set forth, the transfer
of this Convertible Debenture is registrable in the Security Register, upon
surrender of this Convertible Debenture for registration of transfer at the
office or agency of the Company in New York, New York, duly endorsed by, or
accompanied by a written instrument of transfer in form satisfactory to the
Company and the Security Registrar duly executed by, the Holder hereof or his
attorney duly authorized in writing, and thereupon one or more new Convertible
Debentures, of authorized denominations and for the same aggregate principal
amount, will be issued to the designated transferee or transferees.



                                     - 13 -
<PAGE>   107

         The Convertible Debentures are issuable only in registered form without
coupons in denominations of $25 and integral multiples thereof. No service
charge shall be made for any such registration of transfer or exchange, but the
Company may require payment of a sum sufficient to cover any tax or other
governmental charge payable in connection therewith. Prior to due presentment of
this Convertible Debenture for registration of transfer, the Company, the
Trustee and any agent of the Company or the Trustee may treat the Person in
whose name this Convertible Debenture is registered as the owner hereof for all
purposes, whether or not this Convertible Debenture be overdue, and neither the
Company, the Trustee nor any such agent shall be affected by notice to the
contrary. In the event of redemption or conversion of this Convertible Debenture
in part only, a new Convertible Debenture or Convertible Debentures for the
unredeemed or unconverted portion hereof will be issued in the name of the
Holder hereof upon the cancellation hereof.

         (10) Persons Deemed Owners. Except as provided in the Indenture, the
registered Holder of a Convertible Debenture may be treated as its owner for all
purposes.

         (11) Unclaimed Money. If money for the payment of principal or interest
remains unclaimed for two years, the Trustee and the Paying Agent shall pay the
money back to the Company at its written request. After that, Holders of
Convertible Debentures entitled to the money must look to the Company for
payment unless an abandoned property law designates another Person and all
liability of the Trustee and such Paying Agent with respect to such money shall
cease.

         (12) Defaults and Remedies. The Convertible Debentures shall have the
Events of Default as set forth in Section 501 of the Indenture. Subject to
certain limitations in the Indenture, if an Event of Default occurs and is
continuing, the Trustee by notice to the Company or the Holders of at least 25%
in aggregate principal amount of the then outstanding Convertible Debentures by
notice to the Company and the Trustee may declare all the Convertible Debentures
to be due and payable immediately.

         The Holders of a majority in principal amount of the Convertible
Debentures then outstanding by written notice to the Trustee may rescind an
acceleration and its consequences if the rescission would not conflict with any
judgment or decree and if all existing Events of Default have been cured or
waived except nonpayment of principal or interest that has become due solely
because of the acceleration. Holders may not enforce the Indenture or the
Convertible Debentures except as provided in the Indenture. Subject to certain
limitations, Holders of a majority in principal amount of the then outstanding
Convertible Debentures issued under the Indenture may direct the Trustee in its
exercise of any trust or power. The Convertible Debentures are unsecured general
obligations of the 



                                     - 14 -
<PAGE>   108

Company. The Company must furnish annually compliance certificates to the
Trustee. The above description of Events of Default and remedies is qualified by
reference to, and subject in its entirety by, the more complete description
thereof contained in the Indenture.

         (13) Amendments, Supplements and Waivers. The Indenture permits, with
certain exceptions as therein provided, the amendment thereof and the
modification of the rights and obligations of the Company and the rights of the
Holders of the Convertible Debentures under the Indenture at any time by the
Company and the Trustee with the consent of the Holders of a majority in
aggregate principal amount of the Convertible Debentures at the time
Outstanding. The Indenture also contains provisions permitting the Holders of
specified percentages in aggregate principal amount of the Convertible
Debentures at the time Outstanding, on behalf of the Holders of all the
Convertible Debentures, to waive compliance by the Company with certain
provisions of the Indenture and certain past defaults under the Indenture and
their consequences. Any such consent or waiver by the Holder of this Convertible
Debenture shall be conclusive and binding upon such Holder and upon all future
Holders of this Convertible Debenture and of any Convertible Debenture issued
upon the registration of transfer hereof or in exchange herefor or in lieu
hereof, whether or not notation of such consent or waiver is made upon this
Convertible Debenture.

         (14) Trustee Dealings with the Company. The Trustee, in its individual
or any other capacity may become the owner or pledgee of the Convertible
Debentures and may otherwise deal with the Company or an Affiliate with the same
rights it would have, as if it were not Trustee, subject to certain limitations
provided for in the Indenture and in the TIA. Any Agent may do the same with
like rights.

         (15) No Recourse Against Others. A director, officer, employee or
stockholder, as such, of the Company shall not have any liability for any
obligations of the Company under the Convertible Debentures or the Indenture or
for any claim based on, in respect of or by reason of such obligations or their
creation. Each Holder of the Convertible Debentures by accepting a Convertible
Debenture waives and releases all such liability. The waiver and release are
part of the consideration for the issue of the Convertible Debentures.

         (16) Governing Law. THE INTERNAL LAWS OF THE STATE OF NEW YORK SHALL
GOVERN THE INDENTURE AND THE CONVERTIBLE DEBENTURES WITHOUT REGARD TO CONFLICT
OF LAW PROVISIONS THEREOF.

         (17) Authentication. The Convertible Debentures shall not be valid
until authenticated by the manual signature of an authorized officer of the
Trustee or an authenticating agent.

         vote of the Holders of at least the proportion in liquidation amount of
         the Preferred Securities that the relevant Super Majority represents of
         the aggregate principal amount of the Convertible Debentures
         outstanding.

                  The foregoing provisions of this Section 2.6(a) shall be in
lieu of ss. 316(a)(1)(B) of the Trust Indenture Act and such ss. 316(a)(1)(B) of
the Trust Indenture Act is hereby expressly excluded from this Trust Agreement
and the Trust Securities, as permitted by the Trust Indenture Act. Upon such
waiver, any such default shall cease to exist, and any Event of Default with
respect to the Preferred Securities arising therefrom shall be deemed to have
been cured, for every purpose of this Trust Agreement, but no such waiver shall
extend to any subsequent or other default or an Event of Default with respect to
the Preferred Securities or impair any right consequent thereon. Any waiver by
the Holders of the Preferred Securities of an Event of Default with respect to
the Preferred Securities shall also be deemed to constitute a waiver by the
Holders of the Common Securities of any such Event of Default with respect to
the Common Securities for all purposes of this Trust Agreement without any
further act, vote, or consent of the Holders of the Common Securities.

                  (b) The Holders of a majority in liquidation amount of the
Common Securities may, by vote, on behalf of the Holders of all of the Common
Securities, waive any past Event of Default with respect to the Common
Securities and its consequences, provided that, if the underlying Event of
Default under the Indenture:

                          (i)  is not waivable under the Indenture, except where
         the Holders of the Common Securities are deemed to have waived such
         Event of Default under the Trust Agreement as provided below in this
         Section 2.6(b), the Event of Default under the Trust Agreement shall
         also not be waivable; or

                          (ii) requires the consent or vote of a Super Majority
         to be waived, except where the Holders of the Common Securities are
         deemed to have waived such Event of Default under the Trust Agreement
         as provided below in this Section 2.6(b), the Event of Default under
         the Trust Agreement may only be waived by the vote of the Holders of at
         least the proportion in liquidation amount of the Common Securities
         that the relevant Super Majority represents of the aggregate principal
         amount of the Convertible Debentures outstanding;


                                       15

<PAGE>   22


provided further, that each Holder of Common Securities will be deemed to have
waived any such Event of Default and all Events of Default with respect to the
Common Securities and its consequences until all Events of Default with respect
to the Preferred Securities have been cured, waived or otherwise eliminated, and
until such Events of Default have been so cured, waived or otherwise eliminated,
the Property Trustee will be deemed to be acting solely on behalf of the Holders
of the Preferred Securities and only the Holders of the Preferred Securities
will have the right to direct the Property Trustee in accordance with the terms
of the Securities. The foregoing provisions of this Section 2.6(b) shall be in
lieu of ss.ss. 316(a)(1)(A) and 316(a)(1)(B) of the Trust Indenture Act and such
ss.ss. 316(a)(1)(A) and 316(a)(1)(B) of the Trust Indenture Act are hereby
expressly excluded from this Trust Agreement and the Trust Securities, as
permitted by the Trust Indenture Act. Subject to the foregoing provisions of
this Section 2.6(b), upon such waiver, any such default shall cease to exist and
any Event of Default with respect to the Common Securities arising therefrom
shall be deemed to have been cured for every purpose of this Trust Agreement,
but no such waiver shall extend to any subsequent or other default or Event of
Default with respect to the Common Securities or impair any right consequent
thereon.

                  (c) A waiver of an Event of Default under the Indenture by the
Property Trustee at the direction of the Holders of the Preferred Securities,
constitutes a waiver of the corresponding Event of Default under this Trust
Agreement. The foregoing provisions of this Section 2.6(c) shall be in lieu of
ss. 316(a)(1)(B) of the Trust Indenture Act and such ss. 316(a)(1)(B) of the
Trust Indenture Act is hereby expressly excluded from this Trust Agreement and
the Trust Securities, as permitted by the Trust Indenture Act.

SECTION 2.7       Event of Default; Notice.

                  (a) The Property Trustee shall, within 10 days after the
occurrence of an Event of Default, transmit by mail, first class postage
prepaid, to the Holders of the Trust Securities, the Administrative Trustees and
the Depositor, notices of all defaults with respect to the Trust Securities
actually known to a Responsible Officer of the Property Trustee, unless such
defaults have been cured or waived before the giving of such notice (the term
"defaults" for the purposes of this Section 2.7(a) being hereby defined to be an
Event of Default as defined in the Indenture, not including any periods of grace
provided for therein and irrespective of the giving of any notice provided
therein); provided that, except for a default in the payment of principal of (or
premium, if any) or interest on any of the Convertible Debentures or in the
payment of any sinking fund installment established for the Convertible
Debentures, the Property Trustee shall be protected in withholding such notice
if and so long as the board of directors, the executive committee, or a trust
committee of directors and/or Responsible Officers of


                                       16

<PAGE>   23



the Property Trustee in good faith determines that the withholding of such
notice is in the interests of the Holders of the Trust Securities, the
Administrative Trustees and the Depositor.

                  (b) The Property Trustee shall not be deemed to have knowledge
of any default except:

                           (i)  a default under Sections 501(1) and 501(2) of
         the Indenture; or

                           (ii) any default as to which the Property Trustee
         shall have received written notice or of which a Responsible Officer of
         the Property Trustee charged with the administration of the Trust
         Agreement shall have actual knowledge.

               The Trust shall not, and the Issuer Trustees (including the

of all the Convertible Debentures shall be due and payable, or (d) consent to
any amendment, modification or termination of the Indenture or the Convertible
Debentures where such consent shall be required unless the Trust shall have
received an opinion of counsel to the effect that such amendment or
modification will not cause more than an insubstantial risk that (i) the Trust
will be deemed an Investment Company required to be registered under the
Investment Company Act, or (ii) for United States federal income tax purposes
the Trust will not be classified as a grantor trust.

SECTION 3.5         General Authority of the Issuer Trustees.

Trust, no person shall be required to inquire into the authority of the Issuer
Trustees to bind the Trust. Persons

Trust.

SECTION 3.7         Not Responsible for Recitals or Issuance of Trust
                    Securities.
              
               The recitals contained in this Trust Agreement and the Trust
Securities shall be taken as the statements of the Depositor, and the Issuer
Trustees do not assume any responsibility for their correctness. The Issuer

as to the validity or sufficiency of this Trust Agreement or the Trust
Securities.

SECTION 3.8         Duration of Trust.

               The Trust, unless terminated pursuant to the provisions of

SECTION 3.9    Mergers.

          (a)  The Trust may not consolidate, amalgamate, merge with or into, 
or be replaced by, or convey, transfer or lease its properties and assets
substantially as an entirety, to any Person, except as described in Sections
3.9(b) and 3.9(c).

          (b)  The Trust may, with the consent of the majority of the
Administrative Trustees, and without the consent of the Holders of the Trust
Securities, the Delaware Trustee or the Property Trustee, consolidate,
amalgamate, merge with or into, or be replaced by a trust organized as such
under the laws of any state of the United States; provided that:

               (i)  if the Trust is not the survivor, such successor entity
         (the "Successor Entity") either:

                    (A)  expressly assumes all of the obligations of the Trust 
              under the Trust Securities; or



                                      19
<PAGE>   26

                    (B)   substitutes for the Preferred Securities other 
                          securities having substantially the same terms as
                          the Preferred Securities (the "Successor
                          Securities") so long as the Successor Securities
                          rank the same as the Preferred Securities with
                          respect to Distributions, assets and payments upon
                          liquidation, redemption and otherwise;

                          (ii)   the Company expressly acknowledges a trustee 
         of the Successor Entity that possesses the same powers and duties as
         the Property Trustee as the Holder of the Convertible Debentures;

                          (iii)  the Preferred Securities or any Successor
         Securities are listed, or any Successor Securities will be listed upon
         notification of issuance, on any national securities exchange or with
         another organization on which the Preferred Securities are then listed
         or quoted;

                          (iv)   such merger, consolidation, amalgamation or
         replacement does not cause the Preferred Securities (including any
         Successor Securities) to be downgraded by any nationally recognized
         statistical rating organization;

                          (v)    such merger, consolidation, amalgamation or
         replacement does not adversely affect the rights, preferences and
         privileges of the Holders of the Preferred Securities (including any
         Successor Securities) in any material respect (other than with respect
         to any dilution of the Holders' interest in the new entity);

                          (vi)   such Successor Entity has a purpose
         substantially identical to that of the Trust;

                          (vii)  the Depositor guarantees the obligations of
         such Successor Entity under the Successor Securities at least to the
         extent provided by the Preferred Securities Guarantee; and

                          (viii) prior to such merger, consolidation,
         amalgamation or replacement, the Depositor has received an opinion of
         a nationally recognized independent counsel to the Trust reasonably
         acceptable to the Property Trustee and experienced in such matters to
         the effect that:

                                 (A)   such merger, consolidation, amalgamation 
                  or replacement will not adversely affect the rights,
                  preferences and privileges of the Holders of the Trust
                  Securities (including any Successor Securities) in any
                  material respect (other than with respect to any dilution of
                  the Holders' interest in the new entity);



                                       20
<PAGE>   27



                                 (B)   following such merger, consolidation,
                  amalgamation or replacement, neither the Trust nor the
                  Successor Entity will be required to register as an
                  Investment Company; and

                                 (C)   following such merger, consolidation,
                  amalgamation or replacement, the Trust (or the Successor
                  Entity) will be treated as a grantor trust for United States
                  federal income tax purposes.

                  (c) Notwithstanding Section 3.9(b), the Trust shall not,
except with the consent of Holders of 100% in liquidation amount of the Common
Securities, consolidate, amalgamate, merge with or into, or be replaced by any
other entity or permit any other entity to consolidate, amalgamate, merge with
or into, or replace it if such consolidation, amalgamation, merger or
replacement would cause the Trust or Successor Entity to be classified as other
than a grantor trust for United States federal income tax purposes.

SECTION 3.10             Termination of Trust.

                  (a)    The Trust shall terminate:

                         (ii)   upon the filing of a certificate of dissolution
         or its equivalent with respect to the Depositor, the filing of a
         certificate of cancellation with respect to the Trust after having

         the Trust Securities, voting together as a single class, to file such
         certificate of cancellation, or the revocation of the Certificate of
         Incorporation of the Depositor and the expiration of 90 days after the
         date of revocation without a reinstatement thereof;

                         (iii)  upon the entry of a decree of judicial 
         dissolution of the Depositor or the Trust;

                         (iv)   upon the redemption, conversion or exchange of 
         all of the Trust Securities and the amounts necessary for redemption,
         conversion or exchange thereof, including any Additional Interest,
         Liquidated Damages, if any, and Compounded Interest, shall have been
         paid to the Holders in accordance with the terms of the Trust
         Securities;

                         (v)    upon the distribution of all of the Convertible
         Debentures upon the occurrence of a Special Event, except in the case
         of a Tax Event that has occurred and is continuing following which the
         Depositor has elected to pay any additional sums such that the net
         amount received by holders of Preferred Securities in



                                       21

         respect of Distributions is not reduced as a result of such Tax Event
         and the Depositor has not revoked any such election or failed to make
         such payments; or

                    (vi)   the expiration of the term of the Trust on April
         1, 2028.

               (b)   As soon as is practicable after the occurrence of an event 
referred to in Section 3.10(a), the Administrative Trustees shall pay (or make
provision for the payment of) all claims against the Trust and shall execute
and file a certificate of cancellation with the Secretary of State of the State
of Delaware.

               (c)   The provisions of Article IX shall survive the termination 
of the Trust.

Responsible Officer of the Property Trustee occurs and is continuing, the
Property Trustee shall, to the extent as obligated to do so hereunder, for the
benefit of Holders of the Trust Securities, but subject to the rights of the

are specifically set forth in this Trust Agreement and no implied covenants
shall be read into this Trust Agreement against the Property Trustee. In case
an Event of Default has occurred (that has not been cured or waived pursuant to
Section 2.6) of which a Responsible Officer of the Property Trustee has actual
knowledge, the Property Trustee shall exercise such rights and powers vested in
it by this Trust Agreement, and use the same degree of care and skill in its
exercise, as a prudent individual would exercise or use under the circumstances
in the conduct of his or her own affairs.

                  (b) No provision of this Trust Agreement shall be construed
to relieve the Property Trustee from liability for its own grossly negligent
action, its own grossly negligent

failure to act, or its own willful misconduct, except that prior to the
occurrence of an Event of Default and after the curing or waiving of all such
Events of Default that may have occurred, in the absence of bad faith on the
part of the Property Trustee, the Property Trustee may conclusively rely, as to
the truth of the statements and the correctness of the opinions expressed
therein, upon any certificates or opinions furnished to the Property Trustee
and conforming to the requirements of this Trust Agreement; but in the case of
any such certificates or opinions that by any provision hereof are specifically
required to be furnished to the Property Trustee, the Property Trustee shall be
under a duty to examine the same to determine whether or not they conform on
their face to the requirements of this Trust Agreement.

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

                  (d) The Property Trustee shall not be liable with respect to
any action taken or omitted to be taken by it in good faith in accordance with
the direction of the Holders of not less than a majority in liquidation amount
of the Trust Securities relating to the time, method and place of conducting
any proceeding for any remedy available to the Property Trustee, or exercising
any trust or power conferred upon the Property Trustee under this Trust
Agreement.

                  (e) The Property Trustee shall not be responsible for
monitoring the compliance by the Administrative Trustees or the Depositor with
their respective duties under this Trust Agreement, nor shall the Property
Trustee be liable for any default or misconduct of the Administrative Trustees
or the Depositor.

                  (f) No provision of this Trust Agreement shall require the
Property Trustee to expend or risk its own funds or otherwise incur personal
financial liability in the performance of any of its duties or in the exercise
of any of its rights or powers, if it shall have reasonable grounds for
believing that the repayment of such funds or liability is not reasonably
assured to it under the terms of this Trust Agreement or indemnity reasonably
satisfactory to the Property Trustee against such risk or liability is not
reasonably assured to it.

                  (g) The Property Trustee's sole duty with respect to the
custody, safe keeping and physical preservation of the Convertible Debentures
and the Property Account shall be to deal with such property in a similar
manner as the Property Trustee deals with similar property for its own account,
subject to the protections and limitations on liability afforded to the
Property Trustee under this Trust Agreement

and the Trust Indenture Act.

                  (h) The Property Trustee shall not be liable for any interest
on any money received by it except as it may otherwise agree in writing with
the Depositor. Money held by the Property Trustee need not be segregated from
other funds held by it except in relation to the Property Account maintained by
the Property Trustee pursuant to Section 5.11(c)(i) and except to the extent
otherwise required by law.

                  (i) The Property Trustee shall have no duty or liability for
or with respect to the value, genuineness, existence or sufficiency of the
Convertible Debentures or the payment of any taxes or assessments levied
thereon or in connection therewith.

                           (ix)   any action taken by the Property Trustee or 
         its agents hereunder shall bind the Trust and the Holders of the Trust
         Securities, and the signature of the Property Trustee or its agents

         respect of such remedy, right or action, (B) may refrain from
         enforcing such remedy or right or taking such other action until such
         instructions are received, and (C) shall be protected in acting in
         accordance with such instructions;

                       (xi)  except as otherwise expressly provided by this
         Trust Agreement, the Property Trustee shall not be under any
         obligation to take any action that is discretionary under the
         provisions of this Trust Agreement; and

                       (xii) the Property Trustee shall not be liable for any

acts or exercise any right, power, duty or obligation conferred or imposed on
it, in any jurisdiction in which it shall be illegal, or in which the Property
Trustee shall be unqualified or incompetent in accordance with applicable law,

facsimile, with a hard copy by overnight courier) not less than 24 hours before
a meeting. Notices shall contain a brief statement of the time, place and
anticipated purposes of the meeting. The presence (whether in person or by

meeting for the express purpose of objecting to the transaction of any activity
on the ground that the meeting has not been lawfully called or convened. Unless
provided otherwise in this Trust Agreement, any action of the Administrative

               (c) Every Person, by virtue of having become a Holder or a

certificate of authentication shall be substantially in the form of Exhibit A-1

         AGREEMENT.

                  (c) If the Depositary is the Depository Trust Company, the
Global Certificate authenticated and delivered hereunder shall also bear a
legend in substantially the following form, in capital letters and bold-face
type:

         UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED SIGNATORY 
         OF THE DEPOSITORY TRUST COMPANY ("DTC") TO THE TRUST OR ITS AGENT

SECTION 7.5           Execution and Dating of Certificates.
                         
                  The Certificates shall be signed on behalf of the Trust by an
Administrative Trustee. In case any Administrative Trustee who shall have
signed any of the Certificates shall cease to be such Administrative Trustee
before the Certificates so signed shall be delivered by the Trust, such
Certificates nevertheless may be delivered as though the person who signed such
Certificates had not ceased to be such Administrative Trustee; and any
Certificates may be signed on behalf of the Trust by such persons who, at the
actual date of execution of such Certificate, shall be the Administrative
Trustees of the Trust, although at the date of the execution and delivery of
the Trust Agreement any such person was not such an Administrative Trustee.
Each Preferred Security shall be dated the date of its authentication.

                  One Administrative Trustee shall sign the Preferred Security
Certificates for the Trust by manual or facsimile signature. Unless otherwise
determined by the Trust, such signature shall, in the case of Common Security
Certificates, be a manual signature.

                         Securities Certificate.

Agreement shall be registered in the name of the



                                       42

<PAGE>   49



Clearing Agency designated by the Depositor for such Global Certificate or a
nominee thereof and delivered to such Clearing Agency or a nominee thereof or
custodian therefor, and each such Global Certificate shall constitute a
Preferred Security for all purposes of this Trust Agreement.

                  (b) If a Global Certificate is to be exchanged for
Certificated Preferred Securities or canceled in whole, it shall be surrendered
by or on behalf of the Clearing Agency, its nominee or custodian to the
Property Trustee, as Registrar, for exchange or cancellation as provided in
this Article 7. If any Global Certificate is to be exchanged for Certificated
Preferred Securities or cancelled in part, or if another Preferred Security is
to be exchanged in whole or in part for a beneficial interest in any Global
Certificate, in each case, as provided in Section 8.2, then either (i) such
Global Certificate shall be so surrendered for exchange or cancellation as
provided in this Article 7 or (ii) the principal amount thereof (or number of
Preferred Securities represented thereby) shall be reduced or increased by an
amount equal to the portion thereof to be so exchanged or cancelled, or equal
to the principal amount of (or number of securities represented by) such
Certificated Preferred Security to be so exchanged for a beneficial interest
therein, as the case may be, by means of an appropriate adjustment made on the
records of the Property Trustee, as Registrar, whereupon the Property Trustee,
in accordance with the Applicable Procedures, shall instruct the Clearing
Agency or its authorized representative to make a corresponding adjustment to
its records. Upon any such surrender or adjustment of a Global Certificate, an
Administrative Trustee shall execute on behalf of the Trust by manual or
facsimile signature, and the Property Trustee shall, subject to Section 8.2 and
as otherwise provided in this Article 7, authenticate and deliver any Preferred
Securities issuable in exchange for such Global Certificate (or any portion
thereof) to or upon the written order of, and registered in such names as may
be directed by, the Clearing Agency or its authorized representative. Upon the
request of the Property Trustee in connection with the occurrence of any of the
events specified in the preceding paragraph, the Depositor shall promptly make
available to the Property Trustee a reasonable supply of Preferred Securities
that are not in the form of Global Certificates but are in certificated form.
The Property Trustee shall be entitled to conclusively rely upon any order,
direction or request of the Clearing Agency or its authorized representative
which is given or made pursuant to this Article 7 if such order, direction or
request is given or made in accordance with the Applicable Procedures.

be, a Global Certificate, unless such Preferred Security is registered in the
name of a Person other than the Clearing Agency for such Global Certificate or
a nominee thereof.

                  (d) The Clearing Agency or its nominee, as registered owner
of a Global Certificate, shall be the holder of such Global Certificate for all
purposes under this Trust Agreement and the Preferred Securities, and owners of
beneficial interests in a Global Certificate shall hold such interests pursuant
to the Applicable Procedures. Accordingly, any such Owner's beneficial interest
in a Global Certificate will be shown only on, and the transfer of such
interest shall be effected only through, records maintained by the Clearing
Agency or its nominee or its participants and such owners of beneficial
interests in a Global Certificate will not be considered the owners or holders
of such Global Certificate for any purpose of this Trust Agreement or the
Preferred Securities.

                  (e) A single Common Securities Certificate representing the
Common Securities shall initially be issued to the Depositor in the form of a
definitive Common Securities Certificate.

SECTION 7.7           Definitive Preferred Security Certificates.

                  Notwithstanding any other provision in this Trust Agreement,
no Global Certificate may be exchanged in whole or in part for Preferred
Securities registered, and no transfer of a Global Certificate in whole or in
part may be registered, in the name of any Person other than the Clearing
Agency for such Global Certificate or a nominee thereof unless (i) such
Clearing Agency (A) has notified the Trust and the Depositor that it is
unwilling or unable to continue as Clearing Agency for such Global Certificate
or (B) has ceased to be a clearing agency registered as such under the Exchange
Act of 1934, as amended, and in either case the Trust and the Depositor
thereupon fail to appoint a successor Clearing Agency, (ii) the Trust and the
Depositor, at their option, notify the Property Trustee in writing that it
elects to cause the issuance of the Preferred Securities in certificated form
or (iii) there shall have occurred and be continuing an Event of Default or any
event which after notice or lapse of time or both would be an Event of Default.
In all cases, Certificated Preferred Securities delivered in exchange for any
Global Certificate or beneficial interests therein will be registered in the
names, and issued in any approved denominations, requested by or on behalf of
the Clearing Agency (in accordance with its customary procedures).

                  (a) The Restricted Global Certificate and the Certificated

Depositor determines otherwise in accordance with applicable law.

             "THE SECURITIES EVIDENCED HEREBY AND THE COMMON STOCK ISSUABLE 
UPON THEIR CONVERSION AND THE CONVERTIBLE DEBENTURES THAT MAY BE ISSUED IN
EXCHANGE THEREFOR HAVE NOT BEEN REGISTERED UNDER THE U.S. SECURITIES ACT OF
1933, AS AMENDED (THE "SECURITIES ACT"), AND MAY NOT BE OFFERED, SOLD, PLEDGED
OR OTHERWISE TRANSFERRED EXCEPT (1) TO A PERSON WHO THE TRANSFEROR AND ANY
PERSON ACTING ON BEHALF OF SUCH TRANSFEROR REASONABLY BELIEVE IS A QUALIFIED
INSTITUTIONAL BUYER ACQUIRING FOR ITS OWN ACCOUNT OR THE ACCOUNT OF A QUALIFIED
INSTITUTIONAL BUYER IN A TRANSACTION COMPLYING WITH RULE 144A UNDER THE
SECURITIES ACT, (2) IN AN OFFSHORE TRANSACTION COMPLYING WITH RULE 903 OR RULE
904 OF REGULATION S UNDER THE SECURITIES ACT, (3) PURSUANT TO AN EXEMPTION FROM

AVAILABLE) OR (4) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE
SECURITIES ACT AND, IN EACH CASE, IN COMPLIANCE WITH ALL APPLICABLE SECURITIES
LAWS OF THE STATES OF THE UNITED STATES AND OTHER JURISDICTIONS."

         (b) The Regulation S Preferred Securities shall bear the following
legend (the "Regulation S Legend") unless the Depositor determines otherwise in
accordance with the applicable law:

             "THE PREFERRED SECURITIES, THE CONVERTIBLE DEBENTURES, THE SHARES

AMENDED, AND MAY NOT BE OFFERED, SOLD OR DELIVERED IN THE UNITED STATES OR TO,
OR FOR THE ACCOUNT OR BENEFIT OF, ANY U.S. PERSON UNLESS SUCH SECURITIES ARE
REGISTERED UNDER THE SECURITIES ACT OR AN EXEMPTION FROM THE REGISTRATION
REQUIREMENTS THEREOF IS AVAILABLE."

SECTION 7.9         Temporary Certificates.

             Until definitive Certificates are ready for delivery, the
Trust may prepare and, in the case of the Preferred Securities, the Property
Trustee shall authenticate temporary Certificates. Temporary Certificates shall
be substantially in the form of definitive Certificates but may have variations
that the Trust considers appropriate for temporary Certificates. Without
unreasonable delay, the Trust shall prepare and, in the case of the Preferred
Securities, the Property Trustee shall authenticate definitive Certificates in
exchange for temporary Certificates.

SECTION 7.10        Registrar, Paying Agent and Conversion Agent.
                    
             In the event that the Preferred Securities are not in book-entry 
only form, the Trust shall maintain in the



                                      45
<PAGE>   52

Borough of Manhattan, City of New York, State of New York, an office or agency
where Preferred Securities may be presented for registration of transfer or
from exchange ("Registrar"), (ii) an office or agency where Preferred
Securities may be presented for payment ("Paying Agent"). The Trust shall
maintain an office or agency where Securities may be presented for conversion
("Conversion Agent"). The Registrar shall keep a register of the Preferred
Securities and of their transfer and exchange. The Trust may appoint the
Registrar, the Paying Agent and the Conversion Agent and may appoint one or
more co- registrars, one or more additional paying agents and one or more
additional conversion agents in such other locations as it shall determine. The
term "Paying Agent" includes any additional paying agent and the term
"Conversion Agent" includes any additional conversion agent. The Trust may
change any Paying Agent, Registrar, co-registrar or Conversion Agent without
prior notice to any Holder. The Paying Agent shall be permitted to resign as
Paying Agent upon 30 days' written notice to the Administrative Trustees. The
Trust shall notify the Property Trustee of the name and address of any Agent
not a party to this Trust Agreement. If the Trust fails to appoint or maintain
another entity as Registrar, Paying Agent or Conversion Agent, the Property
Trustee shall act as such. The Trust or any of its Affiliates may act as Paying
Agent, Registrar, or Conversion Agent. The Trust shall act as Paying Agent,
Registrar, co-registrar, and Conversion Agent for the Common Securities.

                  The Trust initially appoints the Property Trustee as
Registrar, Paying Agent and Conversion Agent for the Preferred Securities. The
Property Trustee shall be entitled to the protections of Sections 5.12 and 5.13
and Article IX in its capacity as Registrar, Paying Agent and Conversion Agent.

SECTION 7.11             Paying Agent to Hold Money in Trust.
                         
                  The Trust shall require each Paying Agent other than the
Property Trustee to agree in writing that the Paying Agent will hold in trust
for the benefit of Holders or the Property Trustee all money held by the Paying
Agent for the payment of principal or distribution on the Trust Securities, and
will notify the Property Trustee if there are insufficient funds. While any
such insufficiency continues, the Property Trustee may require a Paying Agent
to pay all money held by it to the Property Trustee. The Trust at any time may
require a Paying Agent to pay all money held by it to the Property Trustee and
to account for any money disbursed by it. Upon payment over to the Property
Trustee, the Paying Agent (if other than the Trust or an Affiliate of the
Trust) shall have no further liability for the money. If the Trust or the
Depositor or an Affiliate of the Trust or the Depositor acts as Paying Agent,
it shall segregate and hold in a separate trust fund for the benefit of the
Holders all money held by it as Paying Agent.

SECTION 7.12             Outstanding Preferred Securities.

                  The Preferred Securities outstanding at any time are all the
Preferred Securities authenticated by the Property Trustee except for those
cancelled by it, those delivered to it for cancellation, and those described in
this Section 7.12 as not outstanding.

                  If a Preferred Security is replaced or paid pursuant to
Section 8.3, it ceases to be outstanding unless the Property Trustee receives
proof satisfactory to it that the replaced, paid or purchased Preferred
Security is held by a bona fide purchaser.

                  If Preferred Securities are considered paid in accordance
with the terms of this Trust Agreement, they cease to be outstanding and
interest on them ceases to accrue.

                  A Preferred Security does not cease to be outstanding because
one of the Trust, the Depositor or an Affiliate of the Depositor holds the
Preferred Security.

SECTION 7.13             Preferred Securities in Treasury.

                  In determining whether the Holders of the required amount of
Trust Securities have concurred in any direction, waiver or consent, Preferred
Securities owned by the Trust, the Depositor or an Affiliate of the Depositor,
as the case may be, shall be disregarded and deemed not to be outstanding,
except that for the purposes of determining whether the Property Trustee shall
be fully protected in relying on any such direction, waiver or consent, only
Preferred Securities which the Property Trustee knows are so owned shall be so
disregarded.

SECTION 7.14             Notices to Clearing Agency.

                  Whenever a notice or other communication to the Holders of
Preferred Securities is required under this Trust Agreement, the Administrative
Trustees shall, in the case of any Global Preferred Security, give all such
notices and communications specified herein to be given to the Preferred
Security Holders to the Depositary, and shall have no notice obligations to the
Preferred Security Beneficial Owners.

SECTION 7.15             Appointment of Successor Clearing Agency.
                         
                  If the Depositary elects to discontinue its services as
securities depositary with respect to the Preferred Securities, the
Administrative Trustees may, in their sole discretion, appoint a successor
Clearing Agency with respect to such Preferred Securities.

SECTION 7.16             Deemed Security Holders.

                  The Trustees and any Agent may treat the Person in whose name 
any Certificate shall be registered on the books



                                       47
<PAGE>   54

and records of the Trust as the sole holder of such Certificate and of the
Trust Securities represented by such Certificate for purposes of receiving
Distributions and for all other purposes whatsoever and, accordingly, shall not
be bound to recognize any equitable or other claim to or interest in such
Certificate or in the Trust Securities represented by such Certificate on the
part of any Person, whether or not the Trust shall have actual or other notice
thereof.


                                  ARTICLE VIII

                     TRANSFERS, EXCHANGES AND CANCELLATIONS
                              OF TRUST SECURITIES

SECTION 8.1           General.

                  (a) Where Preferred Security Certificates are presented to
the Registrar or a co-registrar with a request to register a transfer or to
exchange them for an equal number of Preferred Securities represented by
different certificates, the Registrar shall register the transfer or make the
exchange if its requirements for such transactions are met. To permit
registrations of transfers and exchanges, the Trust shall issue and the
Property Trustee shall authenticate Preferred Security Certificates at the
Registrar's request.

                  (b) Trust Securities may only be transferred, in whole or in
part, in accordance with the terms and conditions set forth in this Trust
Agreement and in the Terms set forth in Annex I. Any transfer or purported
transfer of any Security not made in accordance with this Trust Agreement shall
be null and void.

                  (c) Subject to this Article VIII, the Depositor and any
Related Party may only transfer Common Securities to the Depositor or a Related
Party of the Depositor; provided that, any such transfer is subject to the
condition precedent that the transferor obtain the written opinion of
nationally recognized independent counsel experienced in such matters that such
transfer would not cause more than an insubstantial risk that:

                      (i)  the Trust would not be classified for United States 
         federal income tax purposes as a grantor trust; and

                      (ii) the Trust would be an Investment Company or the
         transferee would become an Investment Company.

                  (d) The Administrative Trustees shall provide for the
registration of Trust Securities and of transfers of Trust Securities, which
will be effected without charge but



                                       48

<PAGE>   55


only upon payment (with such indemnity as the Administrative Trustees may
require) in respect of any tax or other governmental charges that may be
imposed in relation to it. Upon surrender for registration of transfer of any
Certificates, the Administrative Trustees shall cause one or more new
Certificates to be issued in the name of the designated transferee or
transferees. Every Certificate surrendered for registration of transfer shall
be accompanied by a written instrument of transfer in form satisfactory to the
Administrative Trustees duly executed by the Holder or such Holder's attorney
duly authorized in writing. Each Certificate surrendered for registration of
transfer shall be canceled by the Administrative Trustees. A transferee of a
Certificate shall be entitled to the rights and subject to the obligations of a
Holder hereunder upon the receipt by such transferee of a Certificate. By
acceptance of a Certificate, each transferee shall be deemed to have agreed to
be bound by this Trust Agreement.

                  (e) The Trust shall not be required (i) to issue, register
the transfer of or exchange Preferred Security Certificates during a period
beginning at the opening of business 15 days before the day of any selection of
Preferred Securities for redemption and ending at 5:00 p.m. (New York City
time) on the day of selection, or (ii) to register the transfer or exchange of
any Preferred Security so selected for redemption in whole or in part, except
the unredeemed portion of any Preferred Security being redeemed in part.

SECTION 8.2           Certain Transfers and Exchanges.

                  (a) Notwithstanding any other provision of this Trust
Agreement or the Preferred Securities, transfers and exchanges of Preferred

Section 8.2.

                      (i) Restricted Global Certificate to Regulation S Global

         effected in accordance with provision of this Clause 8.2(i) and Clause
         8.2 (vi) below and subject to the Applicable Procedures. Upon receipt

         specified participant's account and that a beneficial interest in the
         Restricted Global Certificate in an equal liquidation amount (or
         number of Preferred Securities) be debited from another specified
         participant's account and (B) a Regulation S Certificate, satisfactory
         to the Property Trustee and duly executed by the owner of such

         number of the Restricted Global certificate and increase the share
         number of the Regulation S Global Certificate by such specified

         beneficial interest in the Restricted Global Certificate, such
         transfer may be effected only in accordance with this Clause 8.2(ii)
         and subject to the Applicable Procedures. Upon receipt by the Property
         Trustee, as Registrar, of (A) a written order given by the Clearing
         Agency or its authorized representative directing that a beneficial
         interest in the Restricted Global Certificate in a specified
         Liquidation Amount (or number of Preferred Securities) be credited to

         participant's account and (B) if such transfer is to occur during the
         Restricted Period, a Restricted Securities Certificate, satisfactory
         to the Property Trustee and duly executed by the owner of such
         beneficial interest in the Regulation S Global certificate or his
         attorney duly authorized in writing, then the Property Trustee, as
         Registrar, shall reduce the liquidation amount (or number of Preferred
         Securities) of the Regulation S Global Certificate and increase the
         liquidation amount of (or number of Preferred Securities represented
         by) the Restricted Global Certificate by such specified liquidation
         amount (or number of securities) as provided in Section 7.6(b).

                           (iii) Restricted Non-Global Certificate to 
         Restricted Global Certificate or Regulation S Global Certificate. If
         the Holder of a Restricted Security (other than a Global Certificate)
         wishes at any time to transfer all or any portion of such Restricted
         Security



                                       50
<PAGE>   57



         to a Person who wishes to take delivery thereof in the form of a

         Property Trustee directing that a beneficial interest in the
         Restricted Global Certificate or Regulation S Global Certificate in a
         specified liquidation amount (or number of Preferred Securities) not
         greater than the amount of such Preferred Security be credited to a
         specified participant's account and (B) a Restricted Securities
         Certificate, if the specified account is to be credited with a
         beneficial interest in the Restricted Global Certificate, or a
         Regulation S Certificate, if the specified account is to be credited
         with a beneficial interest in the Regulation S Global Certificate, in
         either case satisfactory to the Property Trustee and duly executed by
         such Holder or his attorney duly authorized in writing, then the
         Property Trustee, as Registrar but subject to Clause 8.2 (vi) below,
         shall cancel such Restricted Security (and issue a new Restricted
         Security in respect of any untransferred portion thereof) as provided
         in Section 7.6(b) and increase the liquidation amount of (or number of
         Preferred Securities represented by) the Restricted Global Certificate
         or the Regulation S Global Certificate, as the case may be, by the
         specified liquidation amount (or number of securities) as provided in
         Section 7.6(b).

                           (iv) Regulation S Non-Global Certificate to
         Restricted Global Certificate or Regulation S Global Certificate. If
         the Holder of a Regulation S Preferred Security (other than a Global
         Certificate) wishes at any time to transfer all or any portion of such
         Regulation S Preferred Security to a Person who wishes to acquire the
         same in the form of a beneficial interest in the Restricted Global
         Certificate or the Regulation S Global Certificate, such transfer may

         specified liquidation amount (or number of Preferred Securities) not
         greater than the amount of such Preferred Security be credited to a
         specified participant's account and (B) if the transfer



                                       51

<PAGE>   58



         is to occur during the Restricted Period and the specified account to
         be credited with a beneficial interest in the Restricted Global
         Certificate, a Restricted Securities Certificate satisfactory to the
         Property Trustee and duly executed by such Holder or his attorney duly
         authorized in writing then the Property Trustee, as Registrar but

         Preferred Security (and issue a new Regulation S Preferred Security in
         respect of any untransferred portion thereof) as provided in Section
         7.6(b) and increase the liquidation amount of (or number of Preferred
         Securities represented by) the Restricted Global Certificate or the

         liquidation amount (or number of securities) as provided in Section
         7.6(b).

                           (v)  Non-Global Certificate to Non-Global 
         Certificate. A Preferred Security that is not a Global Certificate may
         be transferred, in whole or in part, to a Person who takes delivery in
         the form of another Security that is not a Global Certificate as
         provided in Section 7.6, provided that, if the Security to be
         transferred in whole or in part is a Restricted Security, or is a
         Regulation S Preferred Security and the transfer is to occur during
         the Restricted Period, then the Property Trustee shall have received
         (A) a Restricted Securities Certificate, satisfactory to the Property
         Trustee and duly executed by the transferor Holder or his attorney
         duly authorized in writing, in which case the transferee Holder shall
         take delivery in the form of a Restricted Security, or (B) a
         Regulation S Certificate, satisfactory to the Property Trustee and
         duly executed by the transferor Holder or his attorney duly authorized
         in writing, in which case the transferee Holder shall take delivery in
         the form of a Regulation S Preferred Security (subject in every case
         to Section 8.2(b)).

                           (vi) Regulation S Global Certificate to be Held
         Through Euroclear or Cedal during Restricted Period. The Depositor
         shall use its best efforts to cause the Clearing Agency to ensure
         that, until the expiration of the Restricted Period, beneficial
         interests in the Regulation S Global Certificate may be held only in
         or through accounts maintained at the Clearing Agency by Euroclear or
         Cedel (or by participants acting for the account thereof), and no
         Person shall be entitled to effect any transfer or exchange that would
         result in any such interest being held otherwise than in or through
         such an account; provided that this Clause 8.2(vi) shall not prohibit
         any transfer or exchange of such an interest in

         otherwise, shall bear the Securities Act Legend borne by such other
         Preferred Security, provided that, if such new Preferred Security is
         required pursuant to Section 8.2(a)(v) to be issued in the form of a
         Restricted Security, it shall bear a Restricted Securities Legend and,
         if such new Preferred Security is so required to be issued in the form
         of a Regulation S Preferred Security, it shall bear a Regulation S
         Legend;

                      (iii) Any Preferred Securities which are sold or 
         otherwise disposed of pursuant to an effective registration statement
         under the Securities Act, together with their Successor Securities
         shall not bear a Securities Act Legend; the Depositor shall inform the
         Property Trustee in writing of the effective date of any such
         registration statement registering the Preferred Securities under the
         Securities Act and shall notify the Property Trustee at any time when
         prospectuses may not be delivered with respect to Preferred Securities
         to be sold pursuant to such registration statement. The Property
         Trustee shall not be liable for any action taken or omitted to be
         taken by it in good faith in accordance with the aforementioned
         registration statement;

                      (iv)  at any time after the Preferred Securities may be 
         freely transferred without registration under the Securities Act or
         without being subject to transfer restrictions pursuant to the
         Securities Act, a new Preferred Security which does not bear a
         Securities Act Legend may be issued in exchange for or in lieu of a
         Preferred Security (other than a



                                       53
<PAGE>   60



         Global Certificate) or any portion thereof which bears such a legend
         if the Property Trustee has received an Unrestricted Securities
         Certificate, satisfactory to the Property Trustee and duly executed by
         the Holder of such legended Preferred Security or his attorney duly
         authorized in writing, and after such date and receipt of such
         certificate, an Administrative Trustee shall execute on behalf of the
         Trust by manual or facsimile signature, and the Property Trustee shall
         authenticate and deliver such a new Preferred Security in exchange for
         or in lieu of such other Preferred Security as provided in this
         Article 8;

                      (v)  a new Preferred Security which does not bear a
         Securities Act Legend may be issued in exchange for or in lieu of a
         Preferred Security (other than a Global Certificate) or any portion
         thereof which bears such a legend if, in the Depositor's judgment,
         placing such a legend upon such new Preferred Security is not
         necessary to ensure compliance with the registration requirements of
         the Securities Act, and an Administrative Trustee shall execute on
         behalf of the Trust by manual or facsimile signature, and the Property
         Trustee, at the written direction of the Depositor, shall authenticate
         and deliver such a new Preferred Security as provided in this Article
         8; and

                      (vi) notwithstanding the foregoing provisions of this 
         Section 8.2(b), a Successor Security of a Preferred Securities that
         does not bear a particular form of Securities Act Legend shall not
         bear such form of legend unless the Depositor has reasonable cause to
         believe that such Successor Security is a "restricted security" within
         the meaning of Rule 144, in which case an Administrative Trustee shall
         execute on behalf of the Trust by manual or facsimile signature, and
         the Property Trustee, at the written direction of the Depositor, shall
         authenticate and deliver a new Preferred Security bearing a Restricted
         Securities Legend in exchange for such Successor Security as provided
         in this Article 8.

SECTION 8.3           Mutilated, Destroyed, Lost or Stolen Certificates; 
                      Replacement Securities.

                  If the holder of a Trust Security claims that the Certificate
representing such Trust Security has been lost, destroyed or wrongfully taken
or if such Certificate is mutilated and is surrendered to the Trust or in the
case of the Preferred Securities to the Property Trustee, the Trust shall issue
and the Property Trustee shall authenticate a replacement Certificate if the
Property Trustee's and the Trust's requirements, as the case may be, are met.
If required by the Property Trustee or the Trust, an indemnity bond must be
sufficient in the judgment of both to protect



                                       54
<PAGE>   61

the Trustees, the Property Trustee, the Depositor or any authenticating agent
from any loss which any of them may suffer if a Certificate is replaced. The
Company may charge for its expenses in replacing a Certificate.

                  In case any such mutilated, destroyed, lost or stolen Trust
Security has become or is about to become due and payable, the Depositor in its
discretion may, instead of issuing a new Certificate, pay such Trust Security.

                  Every replacement Certificate is an additional obligation of
the Trust.

SECTION 8.4           Cancellation of Preferred Security Certificates.

                  The Trust at any time may deliver Preferred Security
Certificates to the Property Trustee for cancellation. The Registrar, Paying
Agent and Conversion Agent shall forward to the Property Trustee any Preferred
Securities surrendered to them for registration of transfer, redemption,
conversion, exchange or payment. The Property Trustee shall promptly cancel all
Preferred Securities surrendered for registration of transfer, redemption,
conversion, exchange, payment, replacement or cancellation and shall dispose of
cancelled Preferred Securities as the Trust directs. The Trust may not issue
new Preferred Securities to replace Preferred Securities that it has paid or
that have been delivered to the Property Trustee for cancellation or that any
holder has converted.

                           LIMITATION OF LIABILITY OF
                HOLDERS OF TRUST SECURITIES, TRUSTEES AND OTHERS

SECTION 9.1       Liability.

              (a) Except as expressly set forth in this Trust Agreement, the 
Securities Guarantees and the terms of the Trust Securities, the Depositor
shall not be:

                  (i)  personally liable for the return of any portion of the 
         capital contributions (or any return thereon) of the Holders of the 
         Trust Securities which shall be made solely from assets of the Trust; 
         or

                  (ii) required to pay to the Trust or to any Holder of Trust 
         Securities any deficit upon dissolution of the Trust or otherwise.

              (b) The Depositor shall be liable for all of the debts and
obligations of the Trust (other than with respect



                                       55
<PAGE>   62



to the Trust Securities) to the extent not satisfied out of the Trust's assets.

               (c) Pursuant to ss. 3803(a) of the Business Trust Act, the
Holders of the Preferred Securities shall be entitled to the same limitation of
personal liability as is extended to stockholders of private corporations for
profit organized under the General Corporation Law of the State of Delaware.

SECTION 9.2              Exculpation.

               (a) No Indemnified Person shall be liable, responsible or
accountable in damages or otherwise to the Trust or any Covered Person for any
loss, damage or claim incurred by reason of any act or omission performed or
omitted by such Indemnified Person in good faith on behalf of the Trust and in
a manner such Indemnified Person reasonably believed to be within the scope of
the authority conferred on such Indemnified Person by this Trust Agreement or
by law, except that an Indemnified Person shall be liable for any such loss,
damage or claim incurred by reason of such Indemnified Person's gross
negligence or willful misconduct with respect to such acts or omissions.

               (b) An Indemnified Person shall be fully protected in relying in 
good faith upon the records of the Trust and upon such information, opinions,
reports or statements presented to the Trust by any Person as to matters the
Indemnified Person reasonably believes are within such other Person's
professional or expert competence and who has been selected with reasonable
care by or on behalf of the Trust, including information, opinions, reports or
statements as to the value and amount of the assets, liabilities, profits,
losses, or any other facts pertinent to the existence and amount of assets from
which Distributions to Holders of Trust Securities might properly be paid.

SECTION 9.3              Fiduciary Duty.

               (a)  To the extent that, at law or in equity, an Indemnified
Person has duties (including fiduciary duties) and liabilities relating thereto
to the Trust or to any other Covered Person, an Indemnified Person acting under
this Trust Agreement shall not be liable to the Trust or to any other Covered
Person for its good faith reliance on the provisions of this Trust Agreement.
The provisions of this Trust Agreement, to the extent that they restrict the
duties and liabilities of an Indemnified Person otherwise existing at law or in
equity (other than the duties imposed on the Property Trustee under the Trust
Indenture Act), are agreed by the parties hereto to replace such other duties
and liabilities of such Indemnified Person.

<PAGE>   63



               (b) Unless otherwise expressly provided herein:

                   (i)  whenever a conflict of interest exists or arises 
         between an Indemnified Person and any Covered Person or

                   (ii) whenever this Trust Agreement or any other agreement 
         contemplated herein or therein provides that an Indemnified Person
         shall act in a manner that is, or provides terms that are, fair and
         reasonable to the Trust or any Holder of Trust Securities,

the Indemnified Person shall resolve such conflict of interest, take such
action or provide such terms, considering in each case the relative interest of
each party (including its own interest) to such conflict, agreement,
transaction or situation and the benefits and burdens relating to such
interests, any customary or accepted industry practices, and any applicable
generally accepted accounting practices or principles. In the absence of bad
faith by the Indemnified Person, the resolution, action or term so made, taken
or provided by the Indemnified Person shall not constitute a breach of this
Trust Agreement or any other agreement contemplated herein or of any duty or
obligation of the Indemnified Person at law or in equity or otherwise.

               (c) Whenever in this Trust Agreement an Indemnified Person is
permitted or required to make a decision:

                   (i)  in its "discretion" or under a grant of similar         
          authority, the Indemnified Person shall be entitled to consider such
         interests and factors as it desires, including its own interests, and
         shall have no duty or obligation to give any consideration to any
         interest of or factors affecting the Trust or any other Person; or

                   (ii) in its "good faith" or under another express standard, 
         the Indemnified Person shall act under such express standard and shall
         not be subject to any other or different standard imposed by this
         Trust Agreement or by applicable law.

SECTION 9.4        Indemnification.

               (a) (i) The Company shall indemnify, to the full extent 
         permitted by law, any Company Indemnified Person who was or is a party
         or is threatened to be made a party to any threatened, pending or
         completed action, suit or proceeding, whether civil, criminal,
         administrative or investigative (other than an action by or in the
         right of the Trust) by reason of the fact that he is or was a Company
         Indemnified Person against



                                       57
<PAGE>   64



         expenses (including attorneys' fees), judgments, fines and amounts
         paid in settlement actually and reasonably incurred by him in
         connection with such action, suit or proceeding if he acted in good
         faith and in a manner he reasonably believed to be in or not opposed
         to the best interests of the Trust, and, with respect to any criminal
         action or proceeding, had no reasonable cause to believe his conduct
         was unlawful. The termination of any action, suit or proceeding by
         judgment, order, settlement, conviction, or upon a plea of nolo
         contendere or its equivalent, shall not, of itself, create a
         presumption that the Company Indemnified Person did not act in good
         faith and in a manner which he reasonably believed to be in or not
         opposed to the best interests of the Trust, and, with respect to any
         criminal action or proceeding, had reasonable cause to believe that
         his conduct was unlawful.

                  (ii)  The Company shall indemnify, to the full extent
         permitted by law, any Company Indemnified Person who was or is a party
         or is threatened to be made a party to any threatened, pending or
         completed action or suit by or in the right of the Trust to procure a
         judgment in its favor by reason of the fact that he is or was a
         Company Indemnified Person against expenses (including attorneys'
         fees) actually and reasonably incurred by him in connection with the
         defense or settlement of such action or suit if he acted in good faith
         and in a manner he reasonably believed to be in or not opposed to the
         best interests of the Trust and except that no such indemnification
         shall be made in respect of any claim, issue or matter as to which
         such Company Indemnified Person shall have been adjudged to be liable
         to the Trust unless and only to the extent that the Court of Chancery
         of Delaware 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 which such Court of Chancery or such other court shall deem
         proper.

                  (iii) To the extent that a Company Indemnified Person shall
         be successful on the merits or otherwise (including dismissal of an
         action without prejudice or the settlement of an action without
         admission of liability) in defense of any action, suit or proceeding
         referred to in paragraphs (i) and (ii) of this Section 9.4(a), or in
         defense of any claim, issue or matter therein, he shall be
         indemnified, to the full extent permitted by law, against expenses
         (including attorneys' fees) actually and reasonably incurred by him in
         connection therewith.



                                       58
<PAGE>   65



                  (iv) Any indemnification under paragraphs (i) and (ii) of
         this Section 9.4(a) (unless ordered by a court) shall be made by the
         Company only as authorized in the specific case upon a determination
         that indemnification of the Company Indemnified Person is proper in
         the circumstances because he has met the applicable standard of
         conduct set forth in paragraphs (i) and (ii). Such determination shall
         be made (1) by the Administrative Trustees by a majority vote of a
         quorum consisting of such Administrative Trustees who were not parties
         to such action, suit or proceeding, (2) if such a quorum is not
         obtainable, or, even if obtainable, if a quorum of disinterested
         Administrative Trustees so directs, by independent legal counsel in a
         written opinion, or (3) by the Holders of the Common Securities of the
         Trust.

                  (v)  Expenses (including attorneys' fees) incurred by a
         Company Indemnified Person in defending a civil, criminal,
         administrative or investigative action, suit or proceeding referred to
         in paragraphs (i) and (ii) of this Section 9.4(a) shall be paid by the
         Company in advance of the final disposition of such action, suit or
         proceeding upon receipt of an undertaking by or on behalf of such
         Company Indemnified Person to repay such amount if it shall ultimately
         be determined that he is not entitled to be indemnified by the Company
         as authorized in this Section 9.4(a). Notwithstanding the foregoing,
         no advance shall be made by the Company if a determination is
         reasonably and promptly made (i) by the Administrative Trustees by a
         majority vote of a quorum of disinterested Administrative Trustees,
         (ii) if such a quorum is not obtainable, or, even if obtainable, if a
         quorum of disinterested Administrative Trustees so directs, by
         independent legal counsel in a written opinion or (iii) by the Holders
         of the Common Securities of the Trust, that, based upon the facts
         known to the Administrative Trustees, counsel or the Holders of the
         Common Securities at the time such determination is made, such Company
         Indemnified Person acted in bad faith or in a manner that such person
         did not believe to be in or not opposed to the best interests of the
         Trust, or, with respect to any criminal proceeding, that such Company
         Indemnified Person believed or had reasonable cause to believe his
         conduct was unlawful. In no event shall any advance be made in
         instances where the Administrative Trustees, independent legal counsel
         or the Holders of the Common Securities reasonably determine that such
         person deliberately breached his duty to the Trust or the Holders of
         the Common or Preferred Securities.

                  (vi) The indemnification and advancement of expenses provided
         by, or granted pursuant to, the other paragraphs of this Section
         9.4(a) shall not be deemed



                                       59

<PAGE>   66



         exclusive of any other rights to which those seeking indemnification
         and advancement of expenses may be entitled under any agreement, vote
         of stockholders or disinterested directors of the Company or Holders
         of the Preferred Securities of the Trust or otherwise, both as to
         action in his official capacity and as to action in another capacity
         while holding such office. All rights to indemnification under this
         Section 9.4(a) shall be deemed to be provided by a contract between
         the Company and each Company Indemnified Person who serves in such
         capacity at any time while this Section 9.4(a) is in effect. Any
         repeal or modification of this Section 9.4(a) shall not affect any
         rights or obligations then existing.

                  (vii)  The Company or the Trust may purchase and maintain
         insurance on behalf of any person who is or was a Company Indemnified
         Person against any liability asserted against him and incurred by him
         in any such capacity, or arising out of his status as such, whether or
         not the Company would have the power to indemnify him against such
         liability under the provisions of this Section 9.4(a).

                  (viii) For purposes of this Section 9.4(a), references to
         "the Trust" shall include, in addition to the resulting or surviving
         entity, any constituent entity (including any constituent of a
         constituent) absorbed in a consolidation or merger, so that any person
         who is or was a director, trustee, officer or employee of such
         constituent entity, or is or was serving at the request of such
         constituent entity as a director, trustee, officer, employee or agent
         of another entity, shall stand in the same position under the
         provisions of this Section 9.4(a) with respect to the resulting or
         surviving entity as he would have with respect to such constituent
         entity if its separate existence had continued.

                  (ix)   The indemnification and advancement of expenses 
         provided by, or granted pursuant to, this Section 9.4(a) shall, unless
         otherwise provided when authorized or ratified, continue as to a
         person who has ceased to be a Company Indemnified Person and shall
         inure to the benefit of the heirs, executors and administrators of
         such a person.

         (b) The Depositor agrees to indemnify the (i) Property Trustee, (ii)
the Delaware Trustee, (iii) any Affiliate of the Property Trustee and the
Delaware Trustee, and (iv) any officers, directors, shareholders, members,
partners, employees, representatives, custodians, nominees or agents of the
Property Trustee and the Delaware Trustee (each of the Persons in (i) through
(iv) being referred to as a "Fiduciary Indemnified Person") for, and to hold
each



                                       60

<PAGE>   67



Fiduciary Indemnified Person harmless against, any and all loss, liability or
expense including taxes (other than taxes based on the income of such Fiduciary
Indemnified Person) incurred without gross negligence or bad faith on its part,
arising out of or in connection with the acceptance or administration or the
trust or trusts hereunder, including the costs and expenses (including
reasonable legal fees and expenses) of defending itself against or
investigating any claim or liability in connection with the exercise or
performance of any of its powers or duties hereunder. The obligation to
indemnify as set forth in this Section 9.4(b) shall survive the satisfaction
and discharge of this Trust Agreement.

SECTION 9.5         Outside Businesses.

               Any Covered Person, the Depositor, the Delaware Trustee and
its Affiliates and the Property Trustee and its Affiliates may engage in or
possess an interest in other business ventures of any nature or description,
independently or with others, similar or dissimilar to the business of the
Trust, and the Trust and the Holders of Trust Securities shall have no rights
by virtue of this Trust Agreement in and to such independent ventures or the
income or profits derived therefrom, and the pursuit of any such venture, even
if competitive with the business of the Trust, shall not be deemed wrongful or
improper. No Covered Person, the Depositor, the Delaware Trustee, its
Affiliates, or the Property Trustee or its Affiliates shall be obligated to
present any particular investment or other opportunity to the Trust even if
such opportunity is of a character that, if presented to the Trust, could be
taken by the Trust, and any Covered Person, the Depositor, the Delaware
Trustee, its Affiliates and the Property Trustee and its Affiliates shall have
the right to take for its own account (individually or as a partner or
fiduciary) or to recommend to others any such particular investment or other
opportunity. Any Covered Person, the Delaware Trustee, its Affiliates and the
Property Trustee and its Affiliates may engage or be interested in any
financial or other transaction with the Depositor or any Affiliate of the
Depositor, or may act as depositary for, trustee or agent for, or act on any
committee or body of holders of, securities or other obligations of the
Depositor or its Affiliates.

SECTION 10.1          Fiscal Year.

                  The fiscal year ("Fiscal Year") of the Trust shall commence
on October 1st and end on September 30th, unless changed by the requisite vote 
of the Administrative Trustees.

SECTION 10.2          Certain Accounting Matters.

                  (a) At all times during the existence of the Trust, the
Administrative Trustees shall keep, or cause to be kept, full books of account,
records and supporting documents, which shall reflect in reasonable detail,
each transaction of the Trust. The books of account shall be maintained on the
accrual method of accounting, in accordance with generally accepted accounting
principles, consistently applied. The Trust shall use the accrual method of
accounting for United States federal income tax purposes. The books of account
and the records of the Trust shall be examined by and reported upon as of the
end of each Fiscal Year by a firm of independent certified public accountants
selected by the Administrative Trustees.

                  (b) The Administrative Trustees shall cause to be prepared
and delivered to each of the Holders of Trust Securities, within 90 days after
the end of each Fiscal Year of the Trust, annual financial statements of the
Trust, including a balance sheet of the Trust as of the end of such Fiscal
Year, and the related statements of income or loss;

                  (c) The Administrative Trustees shall cause to be duly
prepared and delivered to each of the Holders of Trust Securities, any annual
United States federal income tax information statement required by the Code,
containing such information with regard to the Trust Securities held by each
Holder as is required by the Code and the Treasury Regulations. Notwithstanding
any right under the Code to deliver any such statement at a later date, the
Administrative Trustees shall endeavor to deliver all such statements within 30
days after the end of each Fiscal Year of the Trust.

                  (d) The Administrative Trustees shall cause to be duly

authority.

SECTION 10.3          Banking.

                  The Trust shall maintain one or more bank accounts in the
name and for the sole benefit of the Trust; provided, however, that all
payments of funds in respect of the Convertible Debentures held by the Property
Trustee shall be made directly to the Property Account and no other funds of
the Trust shall be deposited in the Property Account. The sole signatories for
such accounts shall be designated by

the Administrative Trustees; provided, however, that the Property Trustee shall
designate the signatories for the Property Account.

SECTION 10.4         Withholding.

                  The Trust and the Administrative Trustees shall comply with
all withholding requirements under United States federal, state and local law.
The Trust shall request, and the Holders shall provide to the Trust, such forms
or certificates as are necessary to establish an exemption from withholding
with respect to each Holder, and any representations and forms as shall
reasonably be requested by the Trust to assist it in determining the extent of,
and in fulfilling, its withholding obligations. The Administrative Trustee
shall file required forms with applicable jurisdictions and, unless an
exemption from withholding is properly established by a Holder, shall remit
amounts withheld with respect to the Holder to applicable jurisdictions. To the
extent that the Trust is required to withhold and pay over any amounts to any
authority with respect to distributions or allocations to any Holder, the
amount withheld shall be deemed to be a distribution in the amount of the
withholding to the Holder. In the event of any claimed overwithholding, Holders
shall be limited to an action against the applicable jurisdiction. If the
amount required to be withheld was not withheld from actual Distributions made,
the Trust may reduce subsequent Distributions by the amount of such
withholding.

SECTION 11.2          Meetings of the Holders of Trust Securities; Action by 
                      Written Consent.

                  (a) Meetings of the Holders of any class of Trust Securities
may be called at any time by the Administrative Trustees (or as provided in the
terms of the Trust Securities) to consider and act on any matter on which
Holders of such class of Trust Securities are entitled to act under the terms
of this Trust Agreement, the terms of the Trust Securities or the rules of any
stock exchange on which the Preferred Securities are listed or admitted for
trading. The Administrative Trustees shall call a meeting of the Holders of
such class if directed to do so by the Holders of at least 10% in liquidation
amount of such class of Trust Securities. Such direction shall be given by
delivering to the Administrative Trustees one or more calls in a writing
stating that the signing Holders of Trust Securities wish to call a meeting and
indicating the general or specific purpose for which the meeting is to be
called. Any Holders of Trust Securities calling a meeting shall specify in
writing the Certificates held by the Holders of Trust Securities exercising the
right to call a meeting and only those Trust Securities represented by the
Certificates so specified shall be counted for purposes of determining whether
the required percentage set forth in the second sentence of this paragraph has
been met.

                  (b) Except to the extent otherwise provided in the terms of
the Trust Securities, the following provisions shall apply to meetings of

                                       65
<PAGE>   72



                           (i)   notice of any such meeting shall be given to 
         all the Holders of Trust Securities having a right to vote thereat at
         least seven days and not more than 60 days before the date of such
         meeting. Whenever a vote, consent or approval of the Holders of Trust
         Securities is permitted or required under this Trust Agreement or the
         rules of any stock exchange or over-the-counter market on which the
         Preferred Securities are listed or admitted for trading, such vote,
         consent or approval may be given at a meeting of the Holders of Trust
         Securities. Any action that may be taken at a meeting of the Holders
         of Trust Securities may be taken without a meeting if a consent in
         writing setting forth the action so taken is signed by the Holders of
         Trust Securities owning not less than the minimum amount of Trust
         Securities in liquidation amount that would be necessary to authorize
         or take such action at a meeting at which all Holders of Trust
         Securities having a right to vote thereon were present and voting.
         Prompt notice of the taking of action without a meeting shall be given
         to the Holders of Trust Securities entitled to vote who have not
         consented in writing. The Administrative Trustees may specify that any
         written ballot submitted to the Security Holders for the purpose of
         taking any action without a meeting shall be returned to the Trust
         within the time specified by the Administrative Trustees;

                           (ii)  each Holder of a Security may authorize any
         Person to act for it by proxy on all matters in which a Holder of
         Trust Securities is entitled to participate, including waiving notice
         of any meeting, or voting or participating at a meeting. No proxy
         shall be valid after the expiration of 11 months from the date thereof
         unless otherwise provided in the proxy. Every proxy shall be revocable
         at the pleasure of the Holder of Trust Securities executing it. Except
         as otherwise provided herein, all matters relating to the giving,
         voting or validity of proxies shall be governed by the General
         Corporation Law of the State of Delaware relating to proxies, and
         judicial interpretations thereunder, as if the Trust were a Delaware
         corporation and the Holders of the Trust Securities were stockholders
         of a Delaware corporation;

                           (iii) each meeting of the Holders of the Trust
         Securities shall be conducted by the Administrative Trustees or by
         such other Person that the Administrative Trustees may designate; and

                           (iv)  unless the Business Trust Act, this Trust
         Agreement, the terms of the Trust Securities, the Trust Indenture Act
         or the listing rules of any stock exchange on which the Preferred
         Securities are then listed or trading provide otherwise, the
         Administrative

         Trustees, in their sole discretion, shall establish all other
         provisions relating to meetings of Holders of Trust Securities,
         including notice of the time, place or purpose of any meeting at which
         any matter is to be voted on by any Holders of Trust Securities,
         waiver of any such notice, action by consent without a meeting, the
         establishment of a record date, quorum requirements, voting in person
         or by proxy or any other matter with respect to the exercise of any
         such right to vote.

                                  ARTICLE XIII

                                   CONVERSION

SECTION 13.1       Conversion Rights.

               The holders of Trust Securities shall have the right at any
time prior to 5:00 p.m. (New York City time) on the Business Day immediately
preceding the date of repayment of such Trust Securities, whether at maturity
or upon redemption (either at the option of the Company or pursuant to a Tax
Event), at their option, to cause the Conversion Agent to convert Trust
Securities, on behalf of the converting Holders, into shares of Company Common
Stock of the Company in the manner described herein on and subject to the
following terms and conditions:

               The Trust Securities will be convertible at the office of the
Conversion Agent into fully paid and nonassessable shares of Company Common
Stock of the Company pursuant to the Holder's direction to the Conversion Agent
to exchange such Trust Securities for a portion of the Convertible Debentures
theretofore held by the Trust on the basis of one Trust Security per $25
principal amount of Convertible Debentures, and immediately convert such amount
of Convertible Debentures into fully paid and nonassessable shares of Company
Common Stock of the Company at an initial conversion rate of 0.4545 shares of
Company Common Stock of the Company per $25 principal amount of Convertible
Debentures (which is equivalent to a conversion price of $55.00 per share of
Company Common Stock of the Company, subject to certain adjustments set forth
in this Article Thirteen (as so adjusted, the "Conversion Price")).

SECTION 13.2       Conversion Procedures.

               (a) In order to convert Trust Securities into Company Common
Stock, the Holder shall submit to the Conversion Agent an irrevocable request
to convert Trust Securities on behalf of such Holder (the "Conversion
Request"), together, if the Trust Securities are in certificated form, with
such certificates. The Conversion Request shall (i) set forth the number of
Trust Securities to be converted and the name or names, if other than the
Holder, in which the shares of Company Common Stock of the Company should be
issued and (ii) direct the Conversion Agent (A) to exchange such Trust
Securities for a portion of the Convertible Debentures held by the Trust (at
the rate of exchange specified in Section 13.1) and (B) to immediately convert
such Convertible Debentures on behalf of such Holder, into Company Common Stock
of the Company (at the conversion rate specified in Section 13.1).

               (b) The Conversion Agent shall notify the Trust of the Holder's 
election to exchange Trust Securities for a portion of the Convertible
Debentures held by the Trust and the Trust shall, upon receipt of such notice,
deliver to the Conversion Agent the appropriate principal amount of Convertible
Debentures for exchange in accordance with this



                                       70
<PAGE>   77

Article Thirteen. The Conversion Agent shall thereupon notify the Company of
the Holder's election to convert such Convertible Debentures into shares of
Company Common Stock of the Company. Accrued Distributions will not be paid on
Preferred Trust Securities that are converted, nor will any payment, allowance
or adjustment be made for accumulated and unpaid Distributions, whether or not
in arrears, on converted Preferred Securities except that if any Preferred
Security is converted (i) on or after a record date for payment of
Distributions thereon, the Distributions payable on the related payment date
with respect to such Preferred Security shall be distributed to the Holder on
such record date, despite such conversion, and (ii) during an Extension Period
and after the Property Trustee mails a Redemption Distribution Notice with
respect to the Preferred Securities that are converted, accrued and unpaid
Distributions through the date of conversion on such Preferred Securities
called for redemption shall be distributed to the Holder who converts such
Preferred Securities, which Distribution shall be made on the redemption date
fixed for redemption. Except as provided above, neither the Trust nor the
Company will make, or be required to make, any payment, allowance or adjustment
upon any conversion on account of any accumulated and unpaid Distributions
accrued on the Trust Securities (including any Additional Interest, Compounded
Interest or Liquidated Damages, if any) surrendered for conversion, or on
account of any accumulated and unpaid dividends on the shares of Company Common
Stock of the Company issued upon such conversion. The Company shall make no
payment or allowance for distributions on the shares of Company Common Stock of
the Company issued upon such conversion, except to the extent that such shares
of Company Common Stock of the Company are held of record on the record date
for any such distributions and except as provided in Section 1309 of the
Indenture. Trust Securities shall be deemed to have been converted immediately
prior to 5:00 p.m. (New York City time) on the day on which a Conversion
Request relating to such Trust Securities is received by the Trust in
accordance with the foregoing provision (the "Conversion Date"). The Person or
Persons entitled to receive the Company Common Stock of the Company issuable
upon conversion of the Convertible Debentures shall be treated for all purposes
as the record holder or holders of such Company Common Stock of the Company at
such time. As promptly as practicable on or after the Conversion Date, the
Company shall issue and deliver at the office of the Conversion Agent a
certificate or certificates for the number of full shares of Company Common
Stock of the Company issuable upon such conversion, together with the cash
payment, if any, in lieu of any fraction of any share to the Person or Persons
entitled to receive the same, unless otherwise directed by the Holder in the
notice of conversion and the Conversion Agent shall distribute such certificate
or certificates to such Person or Persons.

<PAGE>   78



                  (c) Each Holder of a Security by his acceptance thereof
appoints Chase Bank of Texas, National Association (the "Conversion Agent") for
the purpose of effecting the conversion of Trust Securities in accordance with
this Article Thirteen. In effecting the conversion and transactions described
in this Article Thirteen, the Conversion Agent shall be acting as agent of the
Holders of Trust Securities directing it to effect such conversion
transactions. The Conversion Agent is hereby authorized (i) to exchange Trust
Securities from time to time for Convertible Debentures held by the Trust in
connection with the conversion of such Trust Securities in accordance with this
Article Thirteen and (ii) to convert all or a portion of the Convertible
Debentures into Company Common Stock of the Company and thereupon to deliver
such shares of Company Common Stock of the Company in accordance with the
provisions of this Article Thirteen and to deliver to the Trust a new Debenture
or Convertible Debentures for any resulting unconverted principal amount.

                  (d) No fractional shares of Company Common Stock of the
Company will be issued as a result of conversion, but in lieu thereof such
fractional interest will be in cash (based on the last reported sale price of
the Company Common Stock of the Company on the Conversion Date) by the Company
to the Trust, which in turn will make such payment to the Holder or Holders of
Trust Securities so converted.

                  (e) The Company shall at all times reserve and keep available
out of its authorized and unissued Company Common Stock, solely for issuance
upon the conversion of the Convertible Debentures, free from any preemptive or
other similar rights, such number of shares of Company Common Stock of the
Company as shall from time to time be issuable upon the conversion of all the
Convertible Debentures then outstanding. Notwithstanding the foregoing, the
Company shall be entitled to deliver upon conversion of Convertible Debentures,
shares of Company Common Stock of the Company reacquired and held in the
treasury of the Company (in lieu of the issuance of authorized and unissued
shares of Company Common Stock of the Company), so long as any such treasury
shares are free and clear of all liens, charges, security interests or
encumbrances. Any shares of Company Common Stock issued upon conversion of the
Convertible Debentures shall be duly authorized, validly issued, fully paid and
nonassessable. The Trust shall deliver the shares of Company Common Stock
received upon conversion of the Convertible Debentures to the converting Holder
free and clear of all liens, charges, security interests and encumbrances,
except for United States withholding taxes. Each of the Company and the Trust
shall prepare and shall use its best efforts to obtain and keep in force such
governmental or regulatory permits or other authorizations as may be required
by law, and shall comply with all applicable requirements as to registration or
qualification



                                       72

<PAGE>   79

of the Company Common Stock (and all requirements to list the Company Common
Stock issuable upon conversion of Convertible Debentures that are at the time
applicable), in order to enable the Company to lawfully issue Company Common
Stock to the Trust upon conversion of the Convertible Debentures and the Trust
to lawfully deliver the Company Common Stock to each Holder upon conversion of
the Trust Securities.

                  (f) The Company will pay any and all taxes that may be
payable in respect of the issue or delivery of shares of Company Common Stock
on conversion of Convertible Debentures and the delivery of the shares of
Company Common Stock by the Trust upon conversion of the Trust Securities. The
Company shall not, however, be required to pay any tax that may be payable in
respect of any transfer involved in the issue and delivery of shares of Company
Common Stock in a name other than that in which the Trust Securities so
converted were registered, and no such issue or delivery shall be made unless
and until the person requesting such issue has paid to the Trust the amount of
any such tax or has established to the satisfaction of the Trust that such tax
has been paid.

                  (g) Nothing in the preceding Article Thirteen shall limit the
requirement of the Trust to withhold taxes pursuant to the terms of the Trust
Securities or as set forth in Annex I to the Trust Agreement or this agreement
or otherwise require the Property Trustee or the Trust to pay any amounts on
account of such withholdings.

SECTION 13.3          Conversion Price Adjustments.

                  The conversion price shall be subject to adjustment (without
duplication) from time to time as follows:

                  (a) In case the Company shall, while any of the Trust
Securities are outstanding, (i) pay a dividend or make a distribution with
respect to its Company Common Stock in shares of Company Common Stock, (ii)
subdivide its outstanding shares of Company Common Stock, (iii) combine its
outstanding shares of Company Common Stock into a smaller number of shares or
(iv) issue by reclassification of its shares of Company Common Stock any shares
of capital stock of the Company, the conversion price in effect immediately
prior to such action shall be adjusted so that the Holder of any Trust
Securities thereafter surrendered for conversion shall be entitled to receive
the number of shares of capital stock of the Company which he would have owned
immediately following such action had such Trust Securities been converted
immediately prior thereto. An adjustment made pursuant to this Section 13.3(a)
shall become effective immediately after the record date in the case of a
dividend or other distribution and shall become



                                       73

<PAGE>   80



effective immediately after the effective date in case of a subdivision,
combination or reclassification (or immediately after the record date if a
record date shall have been established for such event). If, as a result of an
adjustment made pursuant to this Section 13.3(a), the Holder of any Trust
Securities thereafter surrendered for conversion shall become entitled to
receive shares of two or more classes or series of capital stock of the
Company, the Board of Directors (whose determination shall be conclusive and
shall be described in a Board Resolution filed with the Trustee) shall
determine the allocation of the adjusted conversion price between or among
shares of such classes or series of capital stock.

                  (b) In case the Company shall, while any of the Trust
Securities are outstanding, issue rights or warrants to all holders of its
Company Common Stock entitling them (for a period expiring within 45 days after
the record date mentioned in this Section 13.3(b)) to subscribe for or purchase
shares of Company Common Stock at a price per share less than the current
market price per share of Company Common Stock (as determined pursuant to
Section 13.3(f) below) on such record date, the conversion price for the Trust
Securities shall be adjusted so that the same shall equal the price determined
by multiplying the conversion price in effect immediately prior to the date of
issuance of such rights or warrants by a fraction of which the numerator shall
be the number of shares of Company Common Stock outstanding on the date of
issuance of such rights or warrants plus the number of shares which the
aggregate offering price of the total number of shares so offered for
subscription or purchase would purchase at such current market price, and of
which the denominator shall be the number of shares of Company Common Stock
outstanding on the date of issuance of such rights or warrants plus the number
of additional shares of Company Common Stock offered for subscription or
purchase. Such adjustment shall become effective immediately after the record
date for the determination of stockholders entitled to receive such rights or
warrants. For the purposes of this subsection, the number of shares of Company
Common Stock at any time outstanding shall not include shares held in the
treasury of the Company. The Company shall not issue any rights or warrants in
respect of shares of Company Common Stock held in the treasury of the Company.
In case any rights or warrants referred to in this subsection in respect of
which an adjustment shall have been made shall expire unexercised within 45
days after the same shall have been distributed or issued by the Company, the
conversion price shall be readjusted at the time of such expiration to the
conversion price that would have been in effect if no adjustment had been made
on account of the distribution or issuance of such expired rights or warrants.

                  (c) Subject to the last sentence of this Section 13.3(c), in 
case the Company shall, by dividend or otherwise, distribute to all holders of
its Company Common Stock evidences of its indebtedness, shares of any class or
series of capital stock, cash or assets (including securities, but excluding
any rights or warrants referred to in Section 13.3(b), any dividend or
distribution paid exclusively in cash and any dividend or distribution referred
to in Section 13.3(a)), the conversion price shall be reduced so that the same
shall equal the price determined by multiplying the conversion price in effect
immediately prior to the effectiveness of the conversion price reduction
contemplated by this Section 13.3(c) by a fraction of which the numerator shall
be the current market price per share (determined as provided in Section
13.3(f)) of the Company Common Stock on the date fixed for the payment of such
distribution (the "Reference Date") less the fair market value (as determined
in good faith by the Board of Directors, whose determination shall be
conclusive and described in a resolution of the Board of Directors), on the
Reference Date, of the portion of the evidences of indebtedness, shares of
capital stock, cash and assets so distributed applicable to one share of
Company Common Stock and the denominator shall be such current market price per
share of the Company Common Stock, such reduction to become effective
immediately prior to the opening of business on the day following the Reference
Date. In the event that such dividend or distribution is not so paid or made,
the conversion price shall again be adjusted to be the conversion price which
would then be in effect if such dividend or distribution had not occurred. If
the Board of Directors determines the fair market value of any distribution for
purposes of this Section 13.3(c) by reference to the actual or when issued
trading market for any securities comprising such distribution, it must in
doing so consider the prices in such market over the same period used in
computing the current market price per share of Company Common Stock
(determined as provided in Section 13.3(f)). For purposes of this Section
13.3(c), any dividend or distribution that includes shares of Company Common
Stock or rights or warrants to subscribe for or purchase shares of Company
Common Stock shall be deemed instead to be (1) a dividend or distribution of
the evidences of indebtedness, shares of capital stock, cash or assets other
than such shares of Company Common Stock or such rights or warrants (making any
conversion price reduction required by this Section 13.3(c)) immediately
followed by (2) a dividend or distribution of such shares of Company Common
Stock or such rights or warrants (making any further conversion price reduction
required by Section 13.3(a) or 13.3(b)), except (A) the Reference Date of such
dividend or distribution as defined in this Section 13.3(c) shall be
substituted as (a) "the record date in the case of a dividend or other
distribution," and (b) "the record date for the determination of stockholders
entitled to receive such rights or warrants" and (c) "the date fixed for such



                                       75
<PAGE>   82



determination" within the meaning of Sections 13.3(a) and 13.3(b) and (B) any
shares of Company Common Stock included in such dividend or distribution shall
not be deemed outstanding for purposes of computing any adjustment of the
conversion price in Section 13.3(a).

                  (d) In case the Company shall pay or make a dividend or other
distribution on its Company Common Stock exclusively in cash (excluding all
regular cash dividends, if the annualized amount thereof per share of Company
Common Stock does not exceed 20% of the current market price per share
determined as provided in Section 13.3(f) of the Company Common Stock on the
Trading Day immediately preceding the date of declaration of such dividend),
the conversion price shall be reduced so that the same shall equal the price
determined by multiplying the conversion price in effect immediately prior to
the effectiveness of the conversion price reduction contemplated by this
Section 13.3(d) by a fraction of which the numerator shall be the current
market price per share (determined as provided in Section 13.3(f)) of the
Company Common Stock on the date fixed for the payment of such distribution
less the amount of cash so distributed and not excluded as provided applicable
to one share of Company Common Stock and the denominator shall be such current
market price per share of the Company Common Stock, such reduction to become
effective immediately prior to the opening of business on the day following the
date fixed for the payment of such distribution; provided, however, that in the
event the portion of the cash so distributed applicable to one share of Company
Common Stock is equal to or greater than the current market price per share (as
defined in Section 13.3(f)) of the Company Common Stock on the record date
mentioned above, in lieu of the foregoing adjustment, adequate provision shall
be made so that each Holder of Trust Securities shall have the right to receive
upon conversion the amount of cash such Holder would have received had such
Holder converted each share of the Trust Securities immediately prior to the
record date for the distribution of the cash. In the event that such dividend
or distribution is not so paid or made, the conversion price shall again be
adjusted to be the conversion price which would then be in effect if such
record date had not been fixed.

                  (e) In case a tender or exchange offer (other than an odd-lot
offer) made by the Company or any Subsidiary of the Company for all or any
portion of the Company's Company Common Stock shall expire and such tender or
exchange offer shall involve the payment by the Company or such Subsidiary of
consideration per share of Company Common Stock having a fair market value (as
determined in good faith by the Board of Directors, whose determination shall
be conclusive and described in a resolution of the Board of Directors) at the
last time (the "Expiration Time") tenders



                                       76
<PAGE>   83



or exchanges may be made pursuant to such tender or exchange offer (as it shall
have been amended) that exceeds 110% of the current market price per share
(determined as provided in Section 13.3(f)) of the Company Common Stock on the
Trading Day next succeeding the Expiration Time, the conversion price shall be
reduced so that the same shall equal the price determined by multiplying the
conversion price in effect immediately prior to the effectiveness of the
conversion price reduction contemplated by this Section 13.3(e) by a fraction
of which the numerator shall be the number of shares of Company Common Stock
outstanding (including any tendered or exchanged shares) at the Expiration Time
multiplied by the current market price per share (determined as provided in
Section 13.3(f)) of the Company Common Stock on the Trading Day next succeeding
the Expiration Time and the denominator shall be the sum of (x) the fair market
value (determined as aforesaid) of the aggregate consideration payable to
stockholders based on the acceptance (up to any maximum specified in the terms
of the tender or exchange offer) of all shares validly tendered or exchanged
and not withdrawn as of the Expiration Time (the shares deemed so accepted, up
to any such maximum, being referred to as the "Purchased Shares") and (y) the
product of the number of shares of Company Common Stock outstanding (less any
Purchased Shares) at the Expiration Time and the current market price per share
(determined as provided in Section 13.3(f)) of the Company Common Stock on the
Trading Day next succeeding the Expiration Time, such reduction to become
effective immediately prior to the opening of business on the day following the
Expiration Time.

                  (f) For the purpose of any computation under Section 13.3(b),
13.3(c), 13.3(d) or 13.3(e), the current market price per share of Company
Common Stock on any date in question shall be deemed to be the average of the
daily Closing Prices for the five consecutive Trading Days selected by the
Company commencing not more than 20 Trading Days before, and ending not later
than, the earlier of the day in question or, if applicable, the day before the
"ex" date with respect to the issuance or distribution requiring such
computation; provided, however, that if another event occurs that would require
an adjustment pursuant to Section 13.3(a) through (e), inclusive, the Board of
Directors may make such adjustments to the Closing Prices during such five
Trading Day period as it deems appropriate to effectuate the intent of the
adjustments in this Section 13.3, in which case any such determination by the
Board of Directors shall be set forth in a Board Resolution and shall be
conclusive. For purposes of this paragraph, the term "ex" date, (i) when used
with respect to any issuance or distribution, means the first date on which the
Company Common Stock trades regular way on the New York Stock Exchange or on
such successor securities exchange as the Company Common Stock may be listed or
in the relevant market from which the Closing Prices were obtained without the
right to receive such



                                       77
<PAGE>   84



issuance or distribution, and (ii) when used with respect to any tender or
exchange offer, means the first date on which the Company Common Stock trades
regular way on such securities exchange or in such market after the Expiration
Time of such offer.

                  (g) The Company may make such reductions in the conversion
price, in addition to those required by Sections 13.3(a) through (e), as it
considers to be advisable to avoid or diminish any income tax to holders of
Company Common Stock or rights to purchase Company Common Stock resulting from
any dividend or distribution of stock (or rights to acquire stock) or from any
event treated as such for income tax purposes. The Company from time to time
may reduce the conversion price by any amount for any period of time if the
period is at least 20 days, the reduction is irrevocable during the period, and
the Board of Directors of the Company shall have made a determination that such
reduction would be in the best interest of the Company, which determination
shall be conclusive. Whenever the conversion price is reduced pursuant to the
preceding sentence, the Company shall mail to holders of record of the
Convertible Debentures a notice of the reduction at least 15 days prior to the
date the reduced conversion price takes effect, and such notice shall state the
reduced conversion price and the period it will be in effect.

                  (h) No adjustment in the conversion price shall be required
unless such adjustment would require an increase or decrease of at least 1% in
the conversion price; provided, however, that any adjustments which by reason
of this Section 13.3(h) are not required to be made shall be carried forward
and taken into account in determining whether any subsequent adjustment shall
be required.

                  (i) If any action would require adjustment of the conversion
price pursuant to more than one of the provisions described above, only one
adjustment shall be made and such adjustment shall be the amount of adjustment
that has the highest absolute value to the Holder of the Trust Securities.

SECTION 13.4          Fundamental Change.

                  (a) In the event that the Company is party to any transaction
(including, without limitation, a merger other than a merger that does not
result in a reclassification, conversion, exchange or cancellation of Company
Common Stock), consolidation, sale of all or substantially all of the assets of
the Company, recapitalization or reclassification of Company Common Stock
(other than a change in par value, or from par value to no par value, or from
no par value to par value or as a result of a subdivision or combination of
Company Common Stock) or any compulsory share exchange (each of the foregoing
being



                                       78
<PAGE>   85



referred to as a "Transaction"), in each case, as a result of which shares of
Company Common Stock shall be converted into the right to receive, or shall be
exchanged for, (i) in the case of any Transaction other than a Transaction
involving a Common Stock Fundamental Change (and subject to funds being legally
available for such purpose under applicable law at the time of such
conversion), securities, cash or other property, each Preferred Security shall
thereafter be convertible into the kind and, in the case of a Transaction which
does not involve a Fundamental Change, amount of securities, cash and other
property receivable upon the consummation of such Transaction by a holder of
that number of shares of Company Common Stock into which a Preferred Security
was convertible immediately prior to such Transaction, or (ii) in the case of a
Transaction involving a Common Stock Fundamental Change, common stock, each
Preferred Security shall thereafter be convertible (in the manner described
therein) into common stock of the kind received by holders of Company Common
Stock (but in each case after giving effect to any adjustment discussed below
relating to a Fundamental Change if such Transaction constitutes a Fundamental
Change). The holders of Preferred Securities will have no voting rights with
respect to any Transaction.

                  (b) If any Fundamental Change occurs, then the conversion
price in effect will be adjusted immediately after such Fundamental Change as
described below. In addition, in the event of a Common Stock Fundamental
Change, each Preferred Security shall be convertible solely into common stock
of the kind received by holders of Company Common Stock as a result of such
Common Stock Fundamental Change.

                  (c) The conversion price in the case of any Transaction
involving a Fundamental Change will be adjusted immediately after such
Fundamental Change:

                      (i)  in the case of a Non-Stock Fundamental Change, the 
                  conversion price of the Preferred Securities will thereupon
                  become the lower of (A) the conversion price in effect
                  immediately prior to such Non-Stock Fundamental Change, but
                  after giving effect to any other prior adjustments effected
                  pursuant to the preceding paragraphs, and (B) the greater of
                  the Applicable Price or the then applicable Reference Market
                  Price plus any then-accrued and unpaid distributions on one
                  Preferred Security; and

                      (ii) in the case of a Common Stock Fundamental Change, 
                  the conversion price of the Preferred Securities in effect
                  immediately prior to such Common Stock Fundamental Change,
                  but after giving effect to any other prior adjustments



                                       79
<PAGE>   86



                  effected pursuant to the preceding paragraphs, will thereupon
                  be adjusted by multiplying such conversion price by a
                  fraction of which the numerator will be the Purchaser Stock
                  Price and the denominator will be the Applicable Price;
                  provided, however, that in the event of a Common Stock
                  Fundamental Change in which (A) 100% of the value of the
                  consideration received by a holder of Company Common Stock is
                  common stock of the successor, acquirer, or other third party
                  (and cash, if any, is paid only with respect to any
                  fractional interests in such common stock resulting from such
                  Common Stock Fundamental Change) and (B) all Company Common
                  Stock will be have been exchanged for, converted into, or
                  acquired for common stock (and cash with respect to
                  fractional interests) of the successor, acquirer, or other
                  third party, the conversion price of the Preferred Securities
                  in effect immediately prior to such Common Stock Fundamental
                  Change will thereupon be adjusted by multiplying such
                  conversion price by a fraction of which the numerator will be
                  one and the denominator will be the number of shares of
                  common stock of the successor, acquirer, or other third party
                  received by a holder of one share of Company Common Stock as
                  a result of such Common Stock Fundamental Change.

                  The Company or the Person formed by such consolidation or
resulting from such merger or which acquired such assets or which acquires the
Company's shares, as the case may be, shall make provision in its certificate
or articles of incorporation or other constituent document to establish such
right. Such certificate or articles of incorporation or other constituent
document shall provide for adjustments which, for events subsequent to the
effective date of such certificate or articles of incorporation or other
constituent document, shall be as nearly equivalent as may be practicable to
the adjustments provided for in this Article Thirteen. The above provisions
shall similarly apply to successive transactions of the foregoing type.

SECTION 13.5             Notice of Adjustments of Conversion Price.
                         
                  Whenever the conversion price is adjusted as herein provided:

                  (a) the Company shall compute the adjusted Conversion Price
and shall prepare a certificate signed by the Chief Financial Officer or the
Treasurer of the Company setting forth the adjusted Conversion Price and
showing in reasonable detail the facts upon which such adjustment is based, and
such certificate shall forthwith be filed with



                                       80
<PAGE>   87

the Trustee, the Conversion Agent and the transfer agent for the Preferred
Securities and the Convertible Debentures; and

                  (b) a notice stating the Conversion Price has been adjusted
and setting forth the adjusted Conversion Price shall as soon as practicable be
mailed by the Company to all record holders of Preferred Securities and the
Convertible Debentures at their last addresses as they appear upon the stock
transfer books of the Company and the Trust.

SECTION 13.6          Prior Notice of Certain Events.
                      

                  In case:

                  (a) the Company shall (i) declare any dividend (or any other
distribution) on its Company Common Stock, other than (A) a dividend payable in
shares of Company Common Stock or (B) a dividend payable in cash that would not
require an adjustment pursuant to Section 13.3(c) or 13.3(d), or (ii) authorize
a tender or exchange offer that would require an adjustment pursuant to Section
13.3(e);

                  (b) the Company shall authorize the granting to all holders
of Company Common Stock of rights or warrants to subscribe for or purchase any
shares of stock of any class or series or of any other rights or warrants;

of any reclassification of Company Common Stock (other than a subdivision or
combination of the outstanding Company Common Stock, or a change in par value,
or from par value to no par value, or from no par value to par value), or of
any consolidation or merger to which the Company is a party and for which
approval of any stockholders of the Company shall be required, or of the sale
or transfer of all or substantially all of the assets of the Company or of any
compulsory share exchange whereby the Company Common Stock is converted into
other securities, cash or other property; or

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

then the Company shall (1) if any Preferred Securities are outstanding, cause
to be filed with the transfer agent for the Preferred Securities, and shall
cause to be mailed to the holders of record of the Preferred Securities, at
their last addresses as they shall appear upon the stock transfer books the
Trust or (2) shall cause to be mailed to all Holders at their last addresses as
they shall appear in the Security Register, at least 15 days prior to the
applicable record or effective date hereinafter specified, a notice stating (x)
the date on which a record (if any) is to be taken for the purpose of such
dividend, distribution, rights or warrants or, if a record is not to be taken,
the date as



                                       81
<PAGE>   88


of which the holders of Company Common Stock of record to be entitled to such
dividend, distribution, rights or warrants are to be determined or (y) the date
on which such reclassification, consolidation, merger, sale, transfer, share
exchange, dissolution, liquidation or winding up is expected to become
effective, and the date as of which it is expected that holders of Company
Common Stock of record shall be entitled to exchange their shares of Company
Common Stock for securities, cash or other property deliverable upon such
reclassification, consolidation, merger, sale, transfer, share exchange,
dissolution, liquidation or winding up (but no failure to mail such notice or
any defect therein or in the mailing thereof shall affect the validity of the
corporate action required to be specified in such notice).

SECTION 13.7          Certain Defined Terms.

                  The following definitions shall apply to terms used in this
Article Thirteen:

                  (a) "Closing Price" of any Company Common Stock on any day
shall mean the reported last sale price on such day or in case no sale takes
place on such day, the average of the reported closing bid and asked prices in
each case on the NYSE Consolidated Transactions Tape or, if the stock is not
listed or admitted to trading on the NYSE, on the principal national securities
exchange on which such stock is listed or admitted to trading or, if not listed
or admitted to trading on any national securities exchange, the average of the
closing bid and asked prices as furnished by any NYSE member firm, selected by
the Debenture Trustee for that purpose.

                  (b) "Trading Day" shall mean a day on which securities are
traded on the national securities exchange or quotation system used to
determine the Closing Price.

SECTION 13.8          Certain Additional Rights.

                  In case the Company shall, by dividend or otherwise, declare
or make a distribution on its Company Common Stock referred to in Section
13.3(c) or 13.3(d) (including, without limitation, dividends or distributions
referred to in the last sentence of Section 13.3(c)), the Holder of the Trust
Securities, upon the conversion thereof subsequent to 5:00 p.m. (New York City
time) on the date fixed for the determination of stockholders entitled to
receive such distribution and prior to the effectiveness of the conversion
price adjustment in respect of such distribution, shall also be entitled to
receive for each share of Company Common Stock into which the Trust Securities
are converted, the portion of the shares of Company Common Stock, rights,
warrants, evidences of indebtedness, shares of capital stock, cash and assets
so



                                       82
<PAGE>   89



distributed applicable to one share of Company Common Stock; provided, however,
that, at the election of the Company (whose election shall be evidenced by a
resolution of the Board of Directors) with respect to all Holders so
converting, the Company may, in lieu of distributing to such Holder any portion
of such distribution not consisting of cash or securities of the Company, pay
such Holder an amount in cash equal to the fair market value thereof (as
determined in good faith by the Board of Directors, whose determination shall
be conclusive and described in a resolution of the Board of Directors). If any
conversion of Trust Securities described in the immediately preceding sentence
occurs prior to the payment date for a distribution to holders of Company
Common Stock which the Holder of Trust Securities so converted is entitled to
receive in accordance with the immediately preceding sentence, the Company may
elect (such election to be evidenced by a resolution of the Board of Directors)
to distribute to such Holder a due bill for the shares of Company Common Stock,
rights, warrants, evidences of indebtedness, shares of capital stock, cash or
assets to which such Holder is so entitled, provided, that such due bill (i)
meets any applicable requirements of the principal national securities exchange
or other market on which the Company Common Stock is then traded and (ii)
requires payment or delivery of such shares of Company Common Stock, rights,
warrants, evidences of indebtedness, shares of capital stock, cash or assets no
later than the date of payment or delivery thereof to holders of shares of
Company Common Stock receiving such distribution.

SECTION 13.9          Restrictions on Company Common Stock Issuable Upon 
                      Conversion.

                  (a) Shares of Company Common Stock to be issued upon
conversion of a Trust Security in respect of Restricted Preferred Securities
shall bear such restrictive legends as the Company may provide in accordance
with applicable law.

                  (b) If shares of Company Common Stock to be issued upon
conversion of a Trust Security in respect of Restricted Preferred Securities
are to be registered in a name other than that of the Holder of such Preferred
Security, then the Person in whose name such shares of Company Common Stock are
to be registered must deliver to the Conversion Agent a certificate
satisfactory to the Company and signed by such Person, as to compliance with
the restrictions on transfer applicable to such Preferred Security. Neither the
Trustee nor any Conversion Agent or Registrar shall be required to register in
a name other than that of the Holder shares of Company Common Stock issued upon
conversion of any such Trust Security in respect of such Preferred Securities
not so accompanied by a properly completed certificate.

SECTION 13.10          Trustee Not Responsible for Determining Conversion Price 
                       or Adjustments.

                  Neither the Trustee nor any Conversion Agent shall at any
time be under any duty or responsibility to any Holder of any Trust Security to
determine whether any facts exist which may require any adjustment of the
conversion price, or with respect to the nature or extent of any such
adjustment when made, or with respect to the method employed, or herein or in
any supplemental indenture provided to be employed, in making the same. Neither
the Trustee nor any Conversion Agent shall be accountable with respect to the
validity or value (or the kind of account) of any shares of Company Common
Stock or of any securities or property, which may at any time be issued or
delivered upon the conversion of any Trust Security; and neither the Trustee
nor any Conversion Agent makes any representation with respect thereto. Neither
the Trustee nor any Conversion Agent shall be responsible for any failure of
the Company to make any cash payment or to issue, transfer or deliver any
shares of Company Common Stock or stock certificates or other securities or
property upon the surrender of any Trust Security for the purpose of
conversion, or, except as expressly herein provided, to comply with any of the
covenants of the Company contained in this Article Thirteen.

                                                                         ANNEX I

                                    TERMS OF
              5 1/4% CONVERTIBLE TRUST ISSUED PREFERRED SECURITIES
                      5 1/4% CONVERTIBLE COMMON SECURITIES



                  Pursuant to Section 7.1 of the Amended and Restated
Declaration of Trust, dated as of March 18, 1998 (as amended from time to time,
the "Trust Agreement"), the designation, rights, privileges, restrictions,
preferences and other terms and provisions of the Preferred Securities and the
Common Securities are set out below (each capitalized term used but not defined
herein has the meaning set forth in the Trust Agreement):

1.       Designation and Number.

         (a)      "Preferred Securities":  4,000,000 5 1/4% ConvertibLE
                  Trust Issued Preferred Securities of the Trust
                  with a liquidation amount of $25 per Preferred
                  Security, plus up to an additional 400,000
                  Preferred Securities of the Trust with a
                  liquidation amount of $25 per Preferred Security,
                  solely to cover over-allotments, if any, as
                  provided for in the Purchase Agreement (the
                  "Additional Preferred Securities"), are hereby
                  designated for the purposes of identification only
                  as "5 1/4% Convertible Trust Issued Preferred
                  Securities (liquidation amount of $25 per
                  Preferred Security)" (the "Preferred Securities").
                  The Preferred Security Certificates evidencing the
                  Preferred Securities shall be substantially in the
                  form of Exhibit A-1 to the Trust Agreement, with
                  such changes and additions thereto or deletions
                  therefrom as may be required by ordinary usage,
                  custom or practice or to conform to the rules of
                  any stock exchange or other organization on which
                  the Preferred Securities are listed.

         (b)      "Common Securities":  123,711 Common Securities of
                  the Trust with a liquidation amount of $25 per
                  Common Security, plus up to an additional 12,371



<PAGE>   98



                  Common Securities of the Trust with a liquidation amount of
                  $25 per Common Security to meet the capital requirements of
                  the Trust in the event of an issuance of Additional Preferred
                  Securities, if any, are hereby designated for the purposes of
                  identification only as "5 1/4% Convertible Common Securities
                  (liquidation amount of $25 per Common Security)" (the "Common
                  Securities"). The Common Security Certificates evidencing the
                  Common Securities shall be substantially in the form of
                  Exhibit A-2 to the Trust Agreement, with such changes and
                  additions thereto or deletions therefrom as may be required by
                  ordinary usage, custom or practice.

2.       Distributions.

         (a)      Distributions payable on each Trust Security will
                  be fixed at a rate per annum of 5 1/4% (the "Coupon
                  Rate") of the stated liquidation amount of $25 per
                  Security, such rate being the rate of interest
                  payable on the Convertible Debentures to be held
                  by the Property Trustee.  Distributions in arrears
                  for more than one quarter will bear interest
                  thereon compounded quarterly at the Coupon Rate
                  (to the extent permitted by applicable law).  The
                  term "Distributions" as used herein includes any
                  such interest including any Additional Interest,
                  Compounded Interest and Liquidated Damages (all as
                  defined in the Trust Agreement), if any, payable
                  unless otherwise stated.  A Distribution is
                  payable only to the extent that payments are made
                  in respect of the Convertible Debentures held by
                  the Property Trustee and to the extent the Trust
                  has funds available therefor.  The amount of
                  Distributions payable for any period will be
                  computed for any full quarterly Distribution
                  period on the basis of a 360-day year of twelve
                  30-day months, and for any period shorter than a
                  full quarterly Distribution period for which
                  Distributions are computed, Distributions will be
                  computed on the basis of the actual number of days
                  elapsed per 90-day quarter.

         (b)      Except as otherwise described below, Distributions on the
                  Trust Securities will be cumulative, will accrue from the date
                  of initial issuance and will be payable quarterly in arrears,
                  on the following


                                       I-2


<PAGE>   99



                  dates, which dates correspond to the interest payment dates on
                  the Convertible Debentures: January 1, April 1, July 1 and
                  October 1 of each year, commencing on July 1, 1998, when, as
                  and if available for payment by the Property Trustee. Provided
                  that no Event of Default has occurred and is continuing, the
                  Company has the right at any time during the term of the
                  Convertible Debentures to defer interest payments from time to
                  time by extending the interest payment period for successive
                  periods not exceeding 20 consecutive quarters (each an
                  "Extension Period") for each such period; provided, that no
                  Extension Period may extend beyond the maturity date of the
                  Convertible Debentures. As a consequence of such extension,
                  quarterly Distributions on the Trust Securities would be
                  deferred (though such Distributions would continue to accrue
                  with interest since interest would continue to accrue on the
                  Convertible Debentures) during any such extended interest
                  payment period. In the event that the Company exercises this
                  right, then, during such period the Company has agreed, among
                  other things, (a) not to declare or pay dividends on, or make
                  a distribution with respect to, or redeem or purchase or
                  acquire, or make a liquidation payment with respect to, any of
                  its capital stock (other than (i) purchases or acquisitions of
                  shares of Company Common Stock in connection with the
                  satisfaction by the Company of its obligations under any
                  employee benefit plans or the satisfaction by the Company of
                  its obligations pursuant to any contract or security requiring
                  the Company to purchase shares of Company Common Stock, (ii)
                  as a result of a reclassification of the Company's capital
                  stock or the exchange or conversion of one class or series of
                  the Company's capital stock for another class or series of the
                  Company's capital stock or (iii) the purchase of fractional
                  interests in shares of the Company's capital stock pursuant to
                  the conversion or exchange provisions of such capital stock or
                  the security being converted or exchanged) or make any
                  guarantee payments with respect to the foregoing, (b) not to
                  make any payment of interest, principal or premium, if any, on
                  or repay, repurchase or redeem any debt securities (including
                  guarantees) issued by the Company that rank pari passu with or
                  junior to the


                                       I-3


<PAGE>   100



                  Convertible Debentures and (c) not to make any guarantee
                  payments with respect to the foregoing (other than pursuant to
                  the Preferred Securities Guarantee). Prior to the termination
                  of any such Extension Period, the Company may further extend
                  the interest payment period; provided, that such Extension
                  Period, together with all such previous and further extensions
                  thereof, may not exceed 20 consecutive quarters or extend
                  beyond the maturity date of the Convertible Debentures. Upon
                  the termination of any Extension Period and the payment of all
                  amounts then due, the Company may commence a new Extension
                  Period, subject to the above requirements.

         (c)      Distributions on the Trust Securities will be
                  payable to the Holders thereof as they appear on
                  the books and records of the Trust on the relevant
                  record dates.  The relevant record dates shall be
                  the March 15, June 15, September 15 and December
                  15 prior to the next succeeding payment dates,
                  except as otherwise described in this Annex I to
                  the Trust Agreement.  Subject to any applicable
                  laws and regulations and the provisions of the
                  Trust Agreement, each such payment in respect of
                  the Preferred Securities being held in book-entry
                  form through The Depository Trust Company (the
                  "Depositary") will be made as described under the
                  heading "Description of the Preferred Securities
                  -- Book-Entry Only Issuance - The Depository Trust
                  Company" in the Offering Memorandum.  The relevant
                  record dates for the Common Securities shall be
                  the same record dates as for the Preferred
                  Securities.  Distributions payable on any Trust
                  Securities that are not punctually paid on any
                  Distribution payment date as a result of the
                  Company having failed to make a payment under the
                  Convertible Debentures, will cease to be payable
                  to the Person in whose name such Trust Securities
                  are registered on the relevant record date, and
                  such defaulted Distribution will instead be
                  payable to the Person in whose name such Trust
                  Securities are registered on the special record
                  date or other specified date determined in
                  accordance with the Indenture.  If Distributions
                  are deferred, the deferred Distributions and
                  accrued interest thereon shall be paid to the
                  holders of record of Trust Securities as they
                  appear on the books and records of the Trust on


                                       I-4


<PAGE>   101



                  the record date next following the termination of such
                  deferral period. If any date on which Distributions are
                  payable on the Trust Securities is not a Business Day, then
                  payment of the Distribution payable on such date will be made
                  on the next succeeding day that is a Business Day (and without
                  any distribution or other payment in respect of any such
                  delay) except that, if such Business Day is in the next
                  succeeding calendar year, such payment shall be made on the
                  immediately preceding Business Day, in each case with the same
                  force and effect as if made on such date.

         (d)      In the event of an election by the Holder to
                  convert its Trust Securities through the
                  Conversion Agent into Company Common Stock of the
                  Company pursuant to the terms of the Trust
                  Securities as set forth in this Annex I to the
                  Trust Agreement, accrued Distributions will not be
                  paid on Preferred Securities that are converted,
                  nor will any payment, allowance or adjustment be
                  made for accumulated and unpaid Distributions,
                  whether or not in arrears, on converted Preferred
                  Securities except that if any Preferred Security
                  is converted on or after a record date for payment
                  of Distributions thereon, the Distributions
                  payable on the related payment date with respect
                  to such Preferred Security shall be distributed to
                  the Holder on such record date, despite such
                  conversion.

         (e)      In the event that there is any money or other property held by
                  or for the Trust that is not accounted for hereunder, such
                  property shall be distributed Pro Rata (as defined in
                  paragraph 9) among the Holders of the Trust Securities.

3.       Liquidation Distribution Upon Dissolution.

                  In the event of any voluntary or involuntary dissolution,
winding-up or termination of the Trust (each a "Liquidation"), the then Holders
of the Trust Securities on the date of the Liquidation will be entitled to
receive out of the assets of the Trust available for distribution to Holders of
Trust Securities after satisfaction of liabilities of creditors, Distributions
in an amount equal to the aggregate of the stated liquidation amount of $25 per
Security plus accrued and unpaid Distributions thereon to


                                       I-5


<PAGE>   102



the date of payment (such amount being the "Liquidation Distribution"), unless,
in connection with such Liquidation, Convertible Debentures in an aggregate
principal amount equal to the aggregate stated liquidation amount of such Trust
Securities, with an interest rate equal to the Coupon Rate of, and bearing
accrued and unpaid interest in an amount equal to the accrued and unpaid
Distributions on, such Trust Securities, shall be distributed on a Pro Rata
basis to the Holders of the Trust Securities.

                  If, upon any such Liquidation, the Liquidation Distribution
can be paid only in part because the Trust has insufficient assets available to
pay in full the aggregate Liquidation Distribution, then the amounts payable
directly by the Trust on the Trust Securities shall be paid on a Pro Rata basis
in accordance with paragraph 9 below.

4.       Redemption and Distribution.

         (a)      Upon the repayment of the Convertible Debentures,
                  in whole or in part, whether at maturity or upon
                  redemption (either at the option of the Company or
                  pursuant to a Tax Event), the proceeds from such
                  repayment or payment shall be simultaneously
                  applied to redeem Trust Securities having an
                  aggregate liquidation amount equal to the
                  aggregate principal amount of the Convertible
                  Debentures so repaid or redeemed at a redemption
                  price equal to the redemption price of such repaid
                  or redeemed Convertible Debentures, together with
                  accrued and unpaid Distributions thereon through
                  the date fixed for redemption, payable in cash
                  (the "Redemption Price").

         (b)      If fewer than all the outstanding Trust Securities are to be
                  so redeemed, the Common Securities and the Preferred
                  Securities will be redeemed Pro Rata and the Preferred
                  Securities to be redeemed will be as described in paragraph
                  4(f)(ii) below.

         (c)      If, at any time, a Tax Event or an Investment
                  Company Event (each as defined below and each a
                  "Special Event") shall occur and be continuing,
                  the Administrative Trustees shall, unless the
                  Convertible Debentures are redeemed in the limited
                  circumstances in relation to a Tax Event described
                  in the following paragraph of this paragraph 4(c),
                  dissolve the Trust and, after satisfaction of
                  creditors of the Trust, if any, cause Convertible


                                       I-6


<PAGE>   103



                  Debentures held by the Property Trustee (w) having an
                  aggregate principal amount equal to the aggregate stated
                  liquidation amount of, (x) an interest rate identical to the
                  Coupon Rate of, (y) accrued and unpaid interest on, and (z)
                  the same record dates for payment as, the Trust Securities, to
                  be distributed to the Holders of the Trust Securities in
                  liquidation of such Holders' interest in the Trust on a Pro
                  Rata basis, within 90 days following the occurrence of such
                  Special Event (the "90 Day Period"); provided, however, that
                  in the case of a Tax Event, such dissolution and distribution
                  shall be conditioned on the Property Trustee's receipt of an
                  opinion of a nationally recognized independent tax counsel
                  experienced in such matters (a "No Recognition Opinion"),
                  which opinion may rely on published revenue rulings of the
                  Internal Revenue Service, to the effect that the Holders of
                  the Preferred Securities will not recognize any income, gain
                  or loss for United States federal income tax purposes as a
                  result of such dissolution and distribution of Convertible
                  Debentures, and provided, further, that if at the time there
                  is available to the Trust the opportunity to eliminate, within
                  the 90 Day Period, the Special Event by taking some
                  ministerial action, such as filing a form or making an
                  election, or pursuing some other similar reasonable measure
                  that in the sole judgment of the Company has, or will cause,
                  no adverse effect on the Trust, the Company or the Holders of
                  the Trust Securities and will involve no material cost
                  ("Ministerial Action"), the Trust will pursue such Ministerial
                  Action in lieu of dissolution.

                                    If in the event of a Tax Event, (i) after
                  receipt of a Tax Event Opinion (as defined below) by the
                  Trust, the Property Trustee has received an opinion (a
                  "Redemption Tax Opinion") of a nationally recognized
                  independent tax counsel experienced in such matters that, as a
                  result of a Tax Event, there is more than an insubstantial
                  risk that the Company would be precluded from deducting the
                  interest on the Convertible Debentures for United States
                  federal income tax purposes even if the Convertible Debentures
                  were distributed to the Holders of Trust Securities in
                  liquidation of such Holders' interest in the Trust as
                  described in this paragraph 4(c), or (ii) after


                                       I-7


<PAGE>   104



                  receipt of a Tax Event Opinion, the Administrative Trustees
                  shall have been informed by such tax counsel that a No
                  Recognition Opinion cannot be delivered to the Trust, the
                  Company shall have the right, upon not less than 30 nor more
                  than 60 days' notice, to redeem the Convertible Debentures in
                  whole (but not in part) for cash within 90 days following the
                  occurrence of such Tax Event, and promptly following such
                  redemption, the Trust Securities shall be redeemed at the
                  Redemption Price on a Pro Rata basis at $25 per Trust Security
                  plus accrued and unpaid distributions; provided, however, that
                  if at the time there is available to the Company or the Trust
                  the opportunity to eliminate, within such 90 Day Period, the
                  Tax Event by taking some Ministerial Action that has no
                  adverse effect on the Trust, the Holders of Trust Securities
                  or the Company, the Trust or the Company will pursue such
                  Ministerial Action in lieu of redemption.

                                    "Tax Event" means that the Property Trustee
                  shall have received an opinion of a nationally recognized
                  independent tax counsel experienced in such matters (a
                  "Dissolution Tax Opinion") to the effect that, as a result of
                  (a) any amendment to, or change (including any announced
                  prospective change) in, the laws (or any regulations
                  thereunder) of the United States or any political subdivision
                  or taxing authority thereof or therein, (b) any amendment to,
                  or change in, an interpretation or application of any such
                  laws or regulations by any legislative body, court,
                  governmental agency or regulatory authority (including the
                  enactment of any legislation and the publication of any
                  judicial decision or regulatory determination), (c) any
                  interpretation or pronouncement that provides for a position
                  with respect to such laws or regulations that differs from the
                  theretofore generally accepted position or (d) any action
                  taken by any governmental agency or regulatory authority,
                  which amendment or change is enacted, promulgated, issued or
                  announced or which interpretation or pronouncement is issued
                  or announced or which action is taken, in each case after the
                  date of the Offering Memorandum (collectively, a "Change in
                  Tax Law"), there is more than an insubstantial risk that (i)
                  the Trust is, or will be within 90 days of the date thereof,


                                       I-8


<PAGE>   105



                  subject to United States federal income tax with respect to
                  interest accrued or received on the Convertible Debentures,
                  (ii) the Trust is, or will be within 90 days of the date
                  thereof, subject to more than a de minimis amount of other
                  taxes, duties or other governmental charges, or (iii) interest
                  payable by the Company to the Trust on the Convertible
                  Debentures is not, or within 90 days of the date thereof will
                  not be, deductible by the Company for United States federal
                  income tax purposes. Notwithstanding anything in the previous
                  sentence to the contrary, a Tax Event shall not include any
                  Change in Tax Law that requires the Company for United States
                  federal income tax purposes to defer taking a deduction for
                  any original issue discount ("OID") that accrues with respect
                  to the Convertible Debentures until the interest payment
                  related to such OID is paid by the Company in money; provided,
                  that such Change in Tax Law does not create more than an
                  insubstantial risk that the Company will be prevented from
                  taking a deduction for OID accruing with respect to the
                  Convertible Debentures at a date that is no later than the
                  date the interest payment related to such OID is actually paid
                  by the Company in money.

                                    "Investment Company Event" means that the
                  Property Trustee shall have received an opinion of a
                  nationally recognized independent counsel experienced in
                  practice under the Investment Company Act (an "Investment
                  Company Event Opinion") that, as a result of a change in law
                  or regulation or a change in interpretation or application of
                  law or regulation by any legislative body, court, governmental
                  agency or regulatory authority (a "Change in 1940 Act Law"),
                  there is more than an insubstantial risk that the Trust is or
                  will be considered an Investment Company that is required to
                  be registered under the Investment Company Act, which Change
                  in 1940 Act Law becomes effective on or after the date of the
                  Offering Memorandum.

                                    On the date fixed for any distribution of
                  Convertible Debentures, upon dissolution of the Trust: (i) the
                  Trust Securities will no longer be deemed to be outstanding,
                  (ii) the Depositary or its nominee, as the record holder of
                  such Trust


                                       I-9


<PAGE>   106



                  Securities, will receive a registered global certificate or
                  certificates representing the Convertible Debentures to be
                  delivered upon such distribution and (iii) certificates
                  representing Trust Securities not held by Depositary or its
                  nominee will be deemed to represent beneficial interests in
                  Convertible Debentures having an aggregate principal amount
                  equal to the stated liquidation amount, and bearing accrued
                  and unpaid interest equal to accrued and unpaid Distributions,
                  on such Trust Securities until such certificates are presented
                  to the Company or its agent for transfer or reissuance.

         (d)      The Trust may not redeem fewer than all the outstanding Trust
                  Securities unless all accrued and unpaid Distributions have
                  been paid in cash on all Trust Securities for all quarterly
                  Distribution periods terminating on or before the date fixed
                  for redemption.

         (e)      If the Convertible Debentures are distributed to the Holders 
                  of the Trust Securities, pursuant to the terms of the
                  Indenture, the Company will use its best efforts to have the
                  Convertible Debentures listed on the New York Stock Exchange
                  or on such other exchange as the Preferred Trust Securities
                  were listed immediately prior to the distribution of the
                  Convertible Debentures.

         (f)      Redemption or Distribution Procedures.

                  (i)        Notice of any redemption of, or notice of
                             distribution of Convertible Debentures in
                             exchange for, the Trust Securities (a
                             "Redemption/Distribution Notice") will be
                             given by the Trust by mail to each Holder
                             of Trust Securities to be redeemed or
                             exchanged not fewer than 30 nor more than
                             60 days before the date fixed for
                             redemption or exchange thereof, which, in
                             the case of a redemption, will be the date
                             fixed for redemption of the Convertible
                             Debentures.  For purposes of the
                             calculation of the date of redemption or
                             exchange and the dates on which notices are
                             given pursuant to this paragraph 4(f)(i), a

                             proceedings with respect to any other Holder.

                  (ii)       In the event that fewer than all the outstanding
                             Trust Securities are to be redeemed, then the
                             aggregate liquidation preference of such Trust
                             Securities to be redeemed shall be allocated pro
                             rata among the Preferred Securities and the Common
                             Securities, it being understood that, in respect of
                             Preferred Securities registered in the name of and
                             held of record by the Depositary or its nominee (or
                             any successor Clearing Agency or its nominee), the
                             distribution of the proceeds of such redemption
                             will be made to each Clearing Agency participant
                             (or Person on whose behalf such nominee holds such
                             securities) in accordance with the procedures
                             applied by such agency or nominee. The particular
                             Preferred Securities to be redeemed shall be
                             selected not more than 60 days prior to the
                             redemption date by the Property Trustee from the
                             outstanding Preferred Securities not previously
                             called for redemption, by lot or by such method as
                             the Property Trustee shall deem fair and
                             appropriate and which may provide for the selection

                  (iii)      If Trust Securities are to be redeemed and the
                             Trust gives a Redemption/Distribution Notice (which
                             notice is irrevocable), then, provided that the
                             Company has paid the Property Trustee a sufficient
                             amount of cash in connection with the related
                             redemption or maturity of the Convertible
                             Debentures, (A) with respect to Preferred
                             Securities held in book-entry form, by 12:00 noon,
                             New York City time, on the redemption date, the
                             Trust will deposit irrevocably with the Depositary
                             or its nominee (or successor Clearing Agency or its
                             nominee) funds sufficient to pay the applicable
                             Redemption Price with respect to such Preferred
                             Securities and will give the Depositary irrevocable
                             instructions and authority to pay the applicable
                             Redemption Price to the Holders of such Preferred
                             Securities represented by the Global Certificates,
                             and (B) with respect to Preferred Securities issued
                             in definitive form and Common Securities, the Trust
                             will irrevocably deposit with the Paying Agent
                             funds sufficient to pay the amount payable on
                             redemption to the Holders of such Trust Securities
                             upon surrender of their certificates. If a
                             Redemption/Distribution Notice shall have been
                             given and funds deposited as required, then on the
                             date of such deposit, all rights of Holders of such
                             Trust Securities so called for redemption will
                             cease, except (i) the right of the Holders of such
                             Trust Securities to receive the Redemption Price,
                             but without interest thereon, and (ii) the right to
                             convert such Trust Securities into Company Common
                             Stock in the manner described herein through the
                             close of business on the date fixed for redemption.
                             Neither the Administrative Trustees nor the Trust
                             shall be required to register or cause to be
                             registered the transfer of any Trust Securities
                             that have been so called for redemption. If any
                             date fixed for redemption of Trust Securities is
                             not a Business Day, then payment of the amount
                             payable on such date will be made on the next
                             succeeding day that is a Business

                             Day (without any interest or other payment in
                             respect of any such delay) except that, if such
                             Business Day falls in the next calendar year, such
                             payment will be made on the immediately preceding
                             Business Day, in each case with the same force and
                             effect as if made on such date fixed for
                             redemption. If payment of the Redemption Price in
                             respect of any Trust Securities is improperly
                             withheld or refused and not paid either by the
                             Trust or by the Company as guarantor pursuant to
                             the relevant Securities Guarantee, Distributions on
                             such Trust Securities will continue to accrue at
                             the then applicable rate, from the original
                             redemption date to the date of payment, in which
                             case the actual payment date will be considered the
                             date fixed for redemption for purposes of
                             calculating the amount payable upon redemption
                             (other than for purposes of calculating any
                             premium).

                  (iv)       In the event of any redemption in part, the Trust
                             shall not be required to (i) issue, register the
                             transfer of or exchange of any Preferred Security
                             during a period beginning at the opening of
                             business 15 days before any selection for
                             redemption of Preferred Securities and ending at
                             5:00 p.m. (New York City time) on the earliest date
                             in which the relevant notice of redemption is
                             deemed to have been given to all holders of
                             Preferred Securities to be so redeemed and (ii)
                             register the transfer of or exchange of any
                             Preferred Securities so selected for redemption, in
                             whole or in part, except for the unredeemed portion
                             of any Preferred Securities being redeemed in part.

                  (v)        Redemption/Distribution Notices shall be sent by
                             the Administrative Trustees on behalf of the Trust
                             to (A) in the case of Preferred Securities held in
                             book-entry form, the Depositary and, in the case of
                             Trust Securities held in definitive form, the
                             Holders of such certificates and (B) in respect of
                             the Common Securities, the Holder thereof.

                  (vi)       Subject to the foregoing and applicable law
                             (including, without limitation, United States
                             federal securities laws), the Company or any of its
                             subsidiaries may at any time and from time to time
                             purchase outstanding Preferred Securities by
                             tender, in the open market or by private agreement.

5.       Conversion Rights.

         The Holders of Trust Securities shall have the right at any time prior
         to 5:00 p.m. (New York City time) on the Business Day immediately
         preceding the date of repayment of such Trust Securities, whether at
         maturity or upon redemption (either at the option of the Company or
         pursuant to a Tax Event), at their option, to cause the Conversion
         Agent to convert Trust Securities, on behalf of the converting Holders,
         into shares of Company Common Stock of the Company in the manner
         described in, and subject to all of the terms and conditions of,
         Article Thirteen of the Trust Agreement.

6.       Voting Rights - Preferred Securities.

         (a)      Except as provided under paragraph 6(b) and paragraph 8, in
                  the Business Trust Act and as otherwise required by law and
                  the Trust Agreement, the Holders of the Preferred Securities
                  will have no voting rights. No vote or consent of the Holders
                  of the Preferred Securities will be required for the Trust to
                  redeem and cancel Preferred Securities or to distribute the
                  Convertible Debentures in accordance with the Trust Agreement
                  and the terms of the Trust Securities.

         (b)      Subject to the requirements set forth in this paragraph 6(b),
                  the Holders of a majority in liquidation amount of the
                  Preferred Securities, voting separately as a class, may direct
                  the time, method, and place of conducting any proceeding for
                  any remedy available to the Property Trustee and direct the
                  exercise of any trust or power conferred upon the Property
                  Trustee under the Trust Agreement, including the right to
                  direct the Property Trustee, as holder of the Convertible
                  Debentures, to (i) exercise the remedies available to it under
                  the Indenture as a holder of the Convertible Debentures, (ii)
                  waive any past


                                      I-14


<PAGE>   111



                  default and its consequences that are waivable under the
                  Indenture, (iii) exercise any right to rescind or annul a
                  declaration that the principal of all the Convertible
                  Debentures shall be due and payable, or (iv) consent to any
                  amendment, modification or termination of the Indenture or the
                  Convertible Debentures where such consent shall be required;
                  provided, however, that where a consent or action under the
                  Indenture would require the consent or act of the Holders of a
                  Super Majority of Convertible Debentures affected thereby, the
                  Property Trustee may only give such consent or take such
                  action at the written direction of the Holders of at least the
                  proportion in liquidation amount of the Preferred Securities
                  that the relevant Super Majority represents of the aggregate
                  principal amount of the Convertible Debentures outstanding.
                  The Property Trustee shall be under no obligation to revoke
                  any action previously authorized or approved by a vote of the
                  Holders of the Preferred Securities. Other than with respect
                  to directing the time, method and place of conducting any
                  remedy available to the Property Trustee or the Indenture
                  Trustee as set forth above, the Property Trustee shall be
                  under no obligation to take any action in accordance with the
                  directions of the Holders of the Preferred Securities under
                  this paragraph 6 unless the Property Trustee has obtained an
                  opinion of independent tax counsel to the effect that for the
                  purposes of United States federal income tax the Trust will
                  not be classified as other than a grantor trust on account of
                  such action and each Holder will be treated as owning an
                  undivided beneficial interest in the Convertible Debentures.
                  If the Property Trustee fails to enforce its rights under the
                  Convertible Debentures after a Holder of Preferred Securities
                  has made a written request, such Holder of Preferred
                  Securities may directly institute a legal proceeding against
                  the Company to enforce the Property Trustee's rights under the
                  Convertible Debentures without first instituting any legal
                  proceeding against the Property Trustee or any other Person.
                  Notwithstanding the foregoing, if an Event of Default has
                  occurred and is continuing and such event is attributable to
                  the failure of the Company to pay interest or principal on the
                  Convertible Debentures on the


                                      I-15

                  date such interest or principal is otherwise payable (or in
                  the case of redemption on the date fixed for redemption), then
                  a Holder of Preferred Securities may directly institute a
                  proceeding for enforcement of payment to such Holder (a
                  "Direct Action") of the principal of or interest on
                  Convertible Debentures having a principal amount equal to the
                  aggregate liquidation amount of the Preferred Securities of
                  such Holder on or after the respective due date specified in
                  the Convertible Debentures. Except as provided in the
                  preceding sentence, the Holders of Preferred Securities will
                  not be able to exercise directly any other remedy available to
                  the holders of the Convertible Debentures. In connection with
                  such Direct Action, the Company will be subrogated to the
                  rights of such Holder of Preferred Securities under the Trust
                  Agreement to the extent of any payment made by the Company to
                  such Holder of Preferred Securities in such Direct Action.

         (c)      Any required approval or direction of Holders of Preferred
                  Securities may be given at a separate meeting of Holders of
                  Preferred Securities convened for such purpose, at a meeting
                  of all of the Holders of Trust Securities in the Trust or
                  pursuant to written consent. The Property Trustee will cause a
                  notice of any meeting at which Holders of Preferred Securities
                  are entitled to vote, or of any matter upon which action by
                  written consent of such Holders is to be taken, to be mailed
                  to each Holder of record of Preferred Securities. Each such
                  notice will include a statement setting forth the following
                  information (i) the date of such meeting or the date by which
                  such action is to be taken, (ii) a description of any
                  resolution proposed for adoption at such meeting on which such
                  Holders are entitled to vote or of such matter upon which
                  written consent is sought and (iii) instructions for the
                  delivery of proxies or consents.

         (d)      Notwithstanding that Holders of Preferred Securities are
                  entitled to vote or consent under any of the circumstances
                  described above, any of the Preferred Securities that are
                  owned by the Company or any Affiliate of the Company shall not
                  be entitled to vote or consent and shall, for purposes of such
                  vote or consent, be treated as if


                                      I-16

                  such Preferred Securities were not outstanding.

7.       Voting Rights - Common Securities.

         (a)      Except as provided under paragraphs 7(b) and (c) and paragraph
                  8, in the Business Trust Act and as otherwise required by law
                  and the Trust Agreement, the Holders of the Common Securities
                  will have no voting rights. No vote or consent of the Holders
                  of the Common Securities will be required for the Trust to
                  redeem and cancel Common Securities or to distribute the
                  Convertible Debentures in accordance with the Trust Agreement
                  and the terms of the Trust Securities.

         (b)      The Holders of the Common Securities are entitled, in
                  accordance with Article V of the Trust Agreement, to vote to
                  appoint, remove or replace any Trustee or to increase or
                  decrease the number of Trustees.

         (c)      Subject to Section 2.6 of the Trust Agreement and only after
                  the Event of Default with respect to the Preferred Securities
                  has been cured, waived, or otherwise eliminated and subject to
                  the requirements of the penultimate sentence of this paragraph
                  7(c), the Holders of a majority in liquidation amount of the
                  Common Securities, voting separately as a class, may direct
                  the time, method, and place of conducting any proceeding for
                  any remedy available to the Property Trustee, or exercising
                  any trust or power conferred upon the Property Trustee under
                  the Trust Agreement, including (i) directing the time, method,
                  place of conducting any proceeding for any remedy available to
                  the Indenture Trustee, or exercising any trust or power
                  conferred on the Indenture Trustee with respect to the
                  Convertible Debentures, (ii) waive any past default and its
                  consequences that are waivable under Section 513 of the
                  Indenture, (iii) exercise any right to rescind or annul a
                  declaration that the principal of all the Convertible
                  Debentures shall be due and payable, or (iv) consent to any
                  amendment, modification or termination of the Indenture or the
                  Convertible Debentures where such consent shall be required;
                  provided that, where a consent or action under the --------
                  Indenture would require the consent or act of the Holders of a
                  Super Majority in principal amount of


                                      I-17


<PAGE>   114



                  Convertible Debentures affected thereby, the Property Trustee
                  may only give such consent or take such action at the written
                  direction of the Holders of at least the proportion in
                  liquidation amount of the Common Securities which the relevant
                  Super Majority represents of the aggregate principal amount of
                  the Convertible Debentures outstanding. Pursuant to this
                  paragraph 7(c), the Property Trustee shall not revoke any
                  action previously authorized or approved by a vote of the
                  Holders of the Preferred Securities. Other than with respect
                  to directing the time, method and place of conducting any
                  remedy available to the Property Trustee or the Indenture
                  Trustee as set forth above, the Property Trustee shall be
                  under no obligation to take any action in accordance with the
                  directions of the Holders of the Common Securities under this
                  paragraph 7(c) unless the Property Trustee has obtained an
                  opinion of independent tax counsel to the effect that for the
                  purposes of United States federal income tax the Trust will
                  not be classified as other than a grantor trust on account of
                  such action and each Holder will be treated as owning an
                  undivided beneficial interest in the Convertible Debentures.
                  If the Property Trustee fails to enforce its rights under the
                  Convertible Debentures after a Holder of Common Securities has
                  made a written request, such Holder of Common Securities may
                  institute a legal proceeding directly against the Company or
                  any other Person to enforce the Property Trustee's rights
                  under the Convertible Debentures, without first instituting
                  any legal proceeding against the Property Trustee or any other
                  Person.

         (d)      Any approval or direction of Holders of Common Securities may
                  be given at a separate meeting of Holders of Common Securities
                  convened for such purpose, at a meeting of all of the Holders
                  of Securities in the Trust or pursuant to written consent. The
                  Administrative Trustees will cause a notice of any meeting at
                  which Holders of Common Securities are entitled to vote, or of
                  any matter upon which action by written consent of such
                  Holders is to be taken, to be mailed to each Holder of record
                  of Common Securities. Each such notice will include a
                  statement setting forth (i) the date of such meeting or the
                  date by which such


                                      I-18


<PAGE>   115



                  action is to be taken, (ii) a description of any resolution
                  proposed for adoption at such meeting on which such Holders
                  are entitled to vote or of such matter upon which written
                  consent is sought and (iii) instructions for the delivery of
                  proxies or consents.

8.       Amendments to Trust Agreement and Indenture.

         (a)      In addition to any requirements under Section 11.1 of the
                  Trust Agreement, if any proposed amendment to the Trust
                  Agreement provides for, or the Administrative Trustees
                  otherwise propose to effect, (i) any action that would
                  adversely affect the powers, preferences or special rights of
                  the Trust Securities, whether by way of amendment to the Trust
                  Agreement or otherwise, or (ii) the dissolution, winding-up or
                  termination of the Trust, other than as described in Section
                  3.10 of the Trust Agreement, then the Holders of Trust
                  Securities as a class will be entitled to vote on such
                  amendment or proposal (but not on any other amendment or
                  proposal) and such amendment or proposal shall not be
                  effective except with the approval of the Holders of a Super
                  Majority in liquidation amount of the Trust Securities
                  affected thereby, voting together as a single class; provided,
                  however, if any amendment or proposal referred to in clause
                  (i) above would adversely affect only the Preferred Securities
                  or only the Common Securities, then only the affected class
                  will be entitled to vote on such amendment or proposal and
                  such amendment or proposal shall not be effective except with
                  the approval of a Super Majority in liquidation amount of such
                  class of Trust Securities.

         (b)      In the event the consent of the Property Trustee as the holder
                  of the Convertible Debentures is required under the Indenture
                  with respect to any amendment, modification or termination on
                  the Indenture or the Convertible Debentures, the Property
                  Trustee shall request the written direction of the Holders of
                  the Trust Securities with respect to such amendment,
                  modification or termination and shall vote with respect to
                  such amendment, modification or termination as directed by a
                  majority in liquidation amount of the Trust Securities voting
                  together as a single class;


                                      I-19


<PAGE>   116



                  provided, however, that where a consent under the Indenture
                  would require a Super Majority in aggregate principal amount
                  of the Convertible Debentures, the Property Trustee may only
                  give such consent at the written direction of the Holders of
                  at least the same proportion in aggregate stated liquidation
                  preference of the Trust Securities; provided, further, that
                  the Property Trustee shall not take any action in accordance
                  with the directions of the Holders of the Trust Securities
                  under this paragraph 8(b) unless the Property Trustee has
                  obtained an opinion of tax counsel to the effect that for the
                  purposes of United States federal income tax the Trust will
                  not be classified as other than a grantor trust on account of
                  such action.

9.       Pro Rata.

                  A reference in these terms of the Trust Securities to any
payment, distribution or treatment as being "Pro Rata" shall mean pro rata to
each Holder of Trust Securities according to the aggregate liquidation amount of
the Trust Securities held by the relevant Holder in relation to the aggregate
liquidation amount of all Trust Securities outstanding unless, in relation to a
payment, an Event of Default under the Trust Agreement has occurred and is
continuing, in which case any funds available to make such payment shall be paid
first to each Holder of the Preferred Securities pro rata according to the
aggregate liquidation amount of Preferred Securities held by the relevant Holder
relative to the aggregate liquidation amount of all Preferred Securities
outstanding, and only after satisfaction of all amounts owed to the Holders of
the Preferred Securities, to each Holder of Common Securities pro rata according
to the aggregate liquidation amount of Common Securities held by the relevant
Holder relative to the aggregate liquidation amount of all Common Securities
outstanding.

10.      Ranking.

                  The Preferred Securities rank pari passu and payment thereon
shall be made Pro Rata with the Common Securities, provided that, if on any
distribution date or redemption date an Event of Default occurs and is
continuing under the Indenture in respect of the Convertible Debentures held by
the Property Trustee, the rights of Holders of the Common Securities to payment
in respect of Distributions and


                                      I-20


<PAGE>   117



payments upon liquidation, redemption and otherwise are subordinated to the
rights to payment of the Holders of the Preferred Securities.

11.  Subordination

                  Payment of distributions on, and the amount payable upon
redemption of, the Trust Securi ties, as applicable, shall be made pro rata
based on the liquidation amount of the Trust Securities; provided, however,
that, if on any distribution date or redemption date an Event of Default shall
have occurred and be continuing, no payment of any distribution on, or amount
payable upon redemption of, any Common Security, and no other payment on account
of the redemption, liquidation or other acquisition of Common Securities, shall
be made unless payment in full in cash of all accumulated and unpaid
distributions on all outstanding Preferred Securities for all distribution
periods terminating on or prior thereto, or in the case of payment of the amount
payable upon redemption of the Preferred Securities, the full amount of such
amount in respect of all outstanding Preferred Securities shall have been made
or provided for, and all funds available to the Property Trustee shall first be
applied to the payment in full in cash of all distributions on, or the amount
payable upon redemption of, Preferred Securities then due and payable.

         In the case of any Event of Default, the holder of Common Securities
will be deemed to have waived any such Event of Default until all such Events of
Default with respect to the Preferred Securities have been cured, waived or
otherwise eliminated. Until any such Events of Default with respect to the
Preferred Securities have been so cured, waived or otherwise eliminated, the
Property Trustee shall act solely on behalf of the holders of the Preferred
Securities and not the holder of the Common Securities, and only the holders of
the Preferred Securities will have the right to direct the Property Trustee to
act on their behalf.

12.      Acceptance of Securities Guarantee and Indenture.

                  Each Holder of Preferred Securities and Common Securities, by
the acceptance thereof, agrees to the provisions of the Preferred Securities
Guarantee and the Common Securities Guarantee, respectively, including the
subordination provisions therein and to the provisions of the Indenture.


                                      I-21


<PAGE>   118



13.      No Preemptive Rights.

                  The Holders of the Trust Securities shall have no preemptive
rights to subscribe for any additional securities.

14.      Miscellaneous.

                  These terms constitute a part of the Trust Agreement.

                  The Company will provide a copy of the Trust Agreement, the
Preferred Securities Guarantee or the Common Securities Guarantee (as may be
appropriate), and the Indenture to a Holder without charge on written request to
the Company at its principal place of business.

                     5 1/4% Convertible Preferred Securities
           (liquidation amount $25 per Convertible Preferred Security)

                  Central Parking Finance Trust, a statutory business trust

rights, privileges, restrictions, preferences and other terms and provisions of
the Preferred Securities represented hereby are issued and shall in all respects

                  By acceptance, the Holder agrees to treat, for United States
federal income tax purposes, the Convertible Debentures as indebtedness and the
Preferred Securities as evidence of indirect beneficial ownership in the
Convertible Debentures.

hereon has been properly executed, these Preferred Securities shall not be
entitled to any benefit under the Trust Agreement or be valid or obligatory for
any purpose.

                              [REVERSE OF SECURITY]

                  Distributions payable on each Preferred Security will be fixed
at a rate per annum of 5 1/4% (the "Coupon Rate") of the stated liquidation
amount of $25 per Preferred Security, such rate being the rate of interest
payable on the Convertible Debentures to be held by the Property Trustee.
Distributions in arrears for more than one quarter will bear interest thereon
compounded quarterly at the Coupon Rate (to the extent permitted by applicable
law). The term "Distributions" as used herein includes any such interest
including any Additional Interest, Compounded Interest and Liquidated Damages,
if any, payable unless otherwise stated. A Distribution is payable only to the
extent that payments are made in respect of the Convertible Debentures held by
the Property Trustee and to the extent the Trust has funds available therefor.
The amount of Distributions payable for any period will be computed for any full
quarterly Distribution period on the basis of a 360-day year of twelve 30-day
months, and for any period shorter than a full quarterly Distribution period for
which Distributions are computed, Distributions will be computed on the basis of
the actual number of days elapsed per 90-day quarter.

                  Except as otherwise described below, Distributions on the
Preferred Securities will be cumulative, will accrue from the date of initial
issuance and will be payable quarterly in arrears, on the following dates, which
dates correspond to the interest payment dates on the Convertible Debentures:
January 1, April 1, July 1 and October 1 of each year, commencing on July 1,
1998, when, as and if available for payment by the Property Trustee. The Company
has the right at any time during the term of the Convertible Debentures to defer
interest payments from time to time by extending the interest payment period for
successive periods not exceeding 20 consecutive quarters (each an "Extension
Period") for each such period; provided, that no Extension Period may extend
beyond the maturity date of the Convertible Debentures. As a consequence of such
extension, quarterly Distributions on the Preferred Securities would be deferred
(though such Distributions would continue to accrue with interest since interest
would continue to accrue on the Convertible Debentures) during any such extended
interest payment period. In the event that the Company exercises this right,
then, during such period the Company has agreed, among other things, (a) not to
declare or pay dividends on, or make a distribution with respect to, or redeem
or


                                      A-1-6

purchase or acquire, or make a liquidation payment with respect to, any of its
capital stock (other than (i) purchases or acquisitions of shares of Company
Common Stock in connection with the satisfaction by the Company of its
obligations under any employee benefit plans or the satisfaction by the Company
of its obligations pursuant to any contract or security requiring the Company to
purchase shares of Company Common Stock, (ii) as a result of a reclassification
of the Company's capital stock or the exchange or conversion of one class or
series of the Company's capital stock for another class or series of the
Company's capital stock or (iii) the purchase of fractional interests in shares
of the Company's capital stock pursuant to the conversion or exchange provisions
of such capital stock or the security being converted or exchanged) or make any
guarantee payments with respect to the foregoing, (b) not to make any payment of
interest, principal or premium, if any, on or repay, repurchase or redeem any
debt securities (including guarantees) issued by the Company that rank pari
passu with or junior to the Convertible Debentures and (c) not to make any
guarantee payments with respect to the foregoing (other than pursuant to the
Preferred Securities Guarantee). Prior to the termination of any such Extension
Period, the Company may further extend the interest payment period; provided,
that such Extension Period, together with all such previous and further
extensions thereof, may not exceed 20 consecutive quarters or extend beyond the
maturity date of the Convertible Debentures. Upon the termination of any
Extension Period and the payment of all amounts then due, the Company may
commence a new Extension Period, subject to the above requirements.

                  Distributions on the Preferred Securities will be payable to
the Holders thereof as they appear on the books and records of the Trust on the
relevant record dates. The relevant record dates shall be the March 15, June 15,
September 15 and December 15 prior to the next such succeeding payment date,
except as otherwise described in the Trust Agreement.

                  The Preferred Securities shall be redeemable as provided in
the Trust Agreement.

                  The Preferred Securities shall be convertible into shares of
common stock of Central Parking Corporation ("Company Common Stock"), through
(i) the exchange of Preferred Securities for a portion of the Convertible
Debentures and (ii) the immediate conversion of such

                              [REVERSE OF SECURITY]

                  Distributions payable on each Common Security will be fixed at
a rate per annum of 5 1/4% (the "Coupon Rate") of the stated liquidation amount
of $25 per Common Security, such rate being the rate of interest payable on the
Convertible Debentures to be held by the Property Trustee. Distributions in
arrears for more than one quarter will bear interest thereon compounded
quarterly at the Coupon Rate (to the extent permitted by applicable law). The
term "Distributions" as used herein includes any such interest including any
Additional Interest, Compounded Interest and Liquidated Damages, if any, payable
unless otherwise stated. A Distribution is payable only to the extent that
payments are made in respect of the Convertible Debentures held by the Property
Trustee and to the extent the Trust has funds available therefor. The amount of
Distributions payable for any period will be computed for any full quarterly
Distribution period on the basis of a 360-day year of twelve 30-day months, and
for any period shorter than a full quarterly Distribution period for which
Distributions are computed, Distributions will be computed on the basis of the
actual number of days elapsed per 90-day quarter.

                  Except as otherwise described below, Distributions on the
Common Security Securities will be cumulative, will accrue from the date of
initial issuance and will be payable quarterly in arrears, on the following
dates, which dates correspond to the interest payment dates on the Convertible
Debentures: January 1, April 1, July 1 and October 1 of each year, commencing on
July 1, 1998, when, as and if available for payment by the Property Trustee. The
Company has the right at any time during the term of the Convertible Debentures
to defer interest payments from time to time by extending the interest payment
period for successive periods not exceeding 20 consecutive quarters (each an
"Extension Period") for each such period; provided, that no Extension Period may
extend beyond the maturity date of the Convertible Debentures. As a consequence
of such extension, quarterly Distributions on the Common Security Securities
would be deferred (though such Distributions would continue to accrue with
interest since interest would continue to accrue on the Convertible Debentures)
during any such extended interest payment period. In the event that the Company
exercises this right, then, during such period the Company has agreed, among
other things, (a) not to declare or pay dividends on, or make a distribution

Guarantee; and

                  (c)      a term defined anywhere in this Preferred Securities
                           Guarantee has the same meaning throughout;

                  (d)      all references to "the Preferred Securities
                           Guarantee" or "this Preferred Securities Guarantee"

Preferred Guarantee Trustee for the benefit of the Holders of the Preferred
Securities, and the Preferred Guarantee Trustee shall not transfer this
Preferred Securities Guarantee to any Person except a Holder exercising his or
her rights pursuant to Section 5.5(b) or to a Successor Preferred Guarantee

read into this Preferred Securities Guarantee against the Preferred Guarantee
Trustee. In case an Event of Default has occurred (that has not been cured or
waived pursuant to Section 2.6) and is actually known to a Responsible Officer

exercise such of the rights and powers vested in it by this Preferred Securities
Guarantee, and use the same degree of care and skill in its exercise thereof, as
a prudent man would exercise or use under the circumstances in the conduct of
his own affairs.

    (d)           No provision of this Preferred Securities Guarantee shall be 
construed to relieve the Preferred Guarantee Trustee from liability for its own
grossly negligent action, its own grossly negligent failure to act, or its own
willful misconduct, except that:


            (i)   prior to the occurrence of any Event of Default and after the
            curing or waiving of all such Events of Default that may have
            occurred:


                  (A)   the duties and obligations of the Preferred Guarantee

            obligations as are specifically set forth in this Preferred
            Securities Guarantee, and no implied covenants or obligations shall
            be read into this Preferred Securities Guarantee against the

                  (B)   in the absence of bad faith on the part of the Preferred
            Guarantee Trustee, the Preferred Guarantee Trustee may conclusively
            rely, as to the truth of the statements and the correctness of the
            opinions expressed therein, upon any certificates or opinions
            furnished to the Preferred Guarantee Trustee and conforming to the
            requirements of this Preferred Securities Guarantee; but in the case
            of any such certificates or opinions that by any provision hereof
            are specifically required to be furnished to the Preferred Guarantee
            Trustee, the Preferred Guarantee Trustee shall be under a duty to
            examine the same to determine whether or not they conform on their
            face to the requirements of this Preferred Securities Guarantee;


      (ii)  the Preferred Guarantee Trustee shall not be liable for any error of
      judgment made in good faith by a Responsible Officer of the Preferred

      which such judgment was made;


      (iii) the Preferred Guarantee Trustee shall not be liable with respect to
      any action taken or omitted to be taken by it in good faith in accordance
      with the direction of the Holders of not less than a Majority in
      liquidation amount of the Preferred Securities relating to the time,
      method and place of conducting any proceeding for any remedy available to
      the Preferred Guarantee Trustee, or exercising any trust or power
      conferred upon the Preferred Guarantee Trustee under this Preferred
      Securities Guarantee; and

      (iv)  no provision of this Preferred Securities Guarantee shall require
      the Preferred Guarantee Trustee to expend or risk its own funds or
      otherwise incur personal financial liability in the performance of any of
      its duties or in the exercise of any of its rights or powers, if the
      Preferred Guarantee Trustee shall have reasonable grounds for believing
      that the repayment of such funds or liability is not reasonably assured to
      it under the terms of this Preferred

                                       11

<PAGE>   15




                  Securities Guarantee or indemnity, reasonably satisfactory to

                  liability is not reasonably assured to it.

and conclusively rely upon an Officers' Certificate which, upon receipt of such

incurred by it in complying with such request or direction, including such
reasonable advances as may be requested by the Preferred Guarantee Trustee;
provided that nothing contained in this Section 3.2(a)(vi) shall be taken to
relieve the Preferred Guarantee Trustee, upon the occurrence of an Event of
Default, of its obligation to exercise the rights and powers vested in it by
this Preferred Securities Guarantee.

investigation into the facts or matters stated in any resolution, certificate,

under this Preferred Securities Guarantee.

    (b)           Any Holder may directly institute a legal proceeding against

                  "Trust Indenture Act" means the Trust Indenture Act of 1939,
or any successor thereto and the rules, regulations and forms promulgated
thereunder, as the same shall be amended.

                  "Underwriter" means any underwriter of Registrable Securities
in connection with an offering thereof under a Shelf Registration Statement.

                  (b) Wherever there is a reference in this Agreement to a
percentage of the "principal amount" of Registrable Securities or to a
percentage of Registrable Securities, the Preferred Securities and the
Convertible Debentures issuable upon exchange of the Preferred Securities will
be treated as the same class of Securities and Company Common Stock shall be
treated as representing the liquidation amount of Preferred Securities or the
principal amount of Convertible Debentures which was surrendered for conversion
in order to receive such number of shares of Company Common Stock.

                  2. Shelf Registration. (a) The Company and the Trust shall,
within 60 calendar days following the First Closing Date (as defined in the
Purchase Agreement), file with the Commission a Shelf Registration Statement
relating to the offer and sale of the Registrable Securities and, thereafter,
shall use their best efforts to cause such Shelf Registration Statement to be
declared effective under the Act as promptly as practicable and in no event
later than 150 calendar days after the First Closing Date; provided however,
that no Holder shall be entitled to be named as a selling securityholder in the
Shelf Registration Statement or to use the Prospectus forming a part thereof for
resales of Registrable Securities unless such Holder is an Electing Holder.

                  (b) The Company and the Trust shall each use its best efforts:

                  (i)  To keep the Shelf Registration Statement continuously
         effective (subject to any Suspension Period (as defined below)) in
         order to permit the Prospectus forming a part thereof to be usable by
         Electing Holders for resales of Registrable Securities for a period of
         two years after the latest date of original issuance of Preferred
         Securities, or such shorter period that will terminate upon the
         earliest of the following: (A) when all the Preferred Securities
         covered by the Shelf Registration Statement have been sold pursuant to
         the Shelf Registration Statement; (B) when all Convertible Debentures
         issued to Holders, in respect of Preferred Securities that had not been
         sold pursuant to the Shelf Registration Statement, have been sold
         pursuant to the Shelf Registration Statement; (C) when all shares of
         Company Common Stock issued upon conversion of any such Preferred
         Securities or any such Convertible Debentures that have not been sold
         pursuant to the Shelf Registration Statement have been sold pursuant to
         the Shelf Registration Statement; and (D) when, in the written opinion
         of counsel to the Trust and the Company, all outstanding Registrable
         Securities held by persons which are not Affiliates of the Trust or the
         Company may be resold immediately without registration or restriction,
         whether under the Act pursuant to Rule 144(k) or any successor
         provision thereto or otherwise (in any such case, such period being
         called the "Effectiveness Period").

                  (ii) At any time after the Effective Time of the Shelf
         Registration Statement, at the earlier of (i) 30 days after the request
         by any Holder that is not then an Electing Holder identified as a
         selling securityholder in the Prospectus at the Effective Time or (ii)
         the receipt by the Company of Notices and Questionnaires by Holders
         representing 5% or greater of the outstanding Registrable Securities,
         to take any action reasonably necessary to enable such Holder to use
         the Prospectus forming a part thereof for resales of Registrable
         Securities, including, without limitation, any action necessary to
         identify such Holder as a selling securityholder in the Shelf
         Registration Statement and any action required pursuant to Section 3
         (j) hereof; provided, however, that nothing in this subparagraph shall
         relieve such Holder of the obligation to return a completed and signed
         Notice and Questionnaire to the Company or the Trust in accordance with
         Section 3(a)(2) hereof and to provide to the Trust and the Company, in
         writing, any information with


                                        4

<PAGE>   5



         respect to such Holder or the Registrable Securities held by such
         Holder as is, in the reasonable opinion of counsel to the Trust or the
         Company, required under applicable law to enable such Holder to use
         such Prospectus for resales of such Registrable Securities; and

                  (iii) If at any time prior to the end of the Effectiveness
         Period, the Preferred Securities are convertible into securities other
         than Company Common Stock, to cause such securities to be included in
         the Shelf Registration Statement no later than the date on which the
         Preferred Securities may first be converted into such securities.

                  (c) If (i) on or prior to the date 60 days after the First
Closing Date a Shelf Registration Statement has not been filed with the
Commission or (ii) on or prior to the date 150 days after the First Closing Date
such Shelf Registration Statement has not been declared effective or (iii) on or
after the date 60 days following the receipt by the Company of such Notices and
Questionnaires required pursuant to Section 2(b)(ii) hereof, an amendment to the
Shelf Registration Statement has not been filed pursuant to Section 3(j) hereof
(each such event, a "Registration Default"), additional interest ("Liquidated
Damages") will accrue on the Convertible Debentures, and, accordingly,
additional distributions will accrue on the Preferred Securities, from and
including the day following such Registration Default until the earlier of such
date as the Shelf Registration Statement is filed or declared effective, as the
case may be, or the end of the Effectiveness Period. Liquidated Damages will be
paid quarterly in arrears (subject to the Company's right to defer the payment
of Liquidated Damages during any Extension Period (as defined in the
Indenture)), with the first quarterly payment due on the first interest or
distribution payment date, as applicable, following the date on which such
Liquidated Damages begin to accrue, and will accrue at a rate per annum equal to
an additional one-quarter of one percent (0.25%) of the principal amount or
liquidation amount, as applicable, to and including the 60th day following such
Registration Default and one-half of one percent (0.50%) thereof from and after
the 61st day following such Registration Default. In the event that the Shelf
Registration Statement ceases to be effective during the Effectiveness Period
for more than 90 consecutive days or any 120 days, whether or not consecutive,
which time period includes any Suspension Period (as defined below), during any
12-month period, then the interest rate borne by the Convertible Debentures and
the distribution rate borne by the Preferred Securities will each increase by an
additional one-half of one percent (0.50%) per annum from the 91st or 121st day,
as the case may be, of the applicable 12-month period such Shelf Registration
Statement ceases to be effective until such time as the earlier to occur of the
Shelf Registration Statement again becoming effective and the end of the
Effectiveness Period.

                  (d) The Company and the Trust shall each be deemed not to have
used its best efforts to keep the Shelf Registration Statement effective during
the Effectiveness Period if either the Trust or the Company voluntarily takes
any action that would result in Electing Holders not being able to offer and
sell any of their Registrable Securities during such period, unless (i) such
action is required by applicable law, (ii) upon the occurrence of any event
contemplated by paragraph 3(d)(2)(iii) below, and such action is taken by the
Trust or the Company in good faith and for valid business reasons or (iii) the
continued effectiveness of the Shelf Registration Statement would require the
Trust or the Company to disclose a material financing, acquisition or other
corporate development, and the proper officers of the Company shall have
determined in good faith that such disclosure is not in the best interest of the
Company and its stockholders and, in the case of clause (ii) above, the Company
and the Trust thereafter promptly comply with the requirements of paragraph 3(j)
below. Any such period during which the Company and the Trust are permitted to
suspend the effectiveness of the Shelf Registration Statement is referred to
herein as the "Suspension Period."

                  3. Registration Procedures. In connection with the Shelf
Registration Statement, the following provisions shall apply:

                           (a) (1) The Company shall not be required to take any
                  action to name such Holder as a selling securityholder in the
                  Shelf Registration Statement or to enable such Holder to use
                  the Prospectus forming a part thereof for resales of
                  Registrable Securities until such Holder has returned a
                  completed and signed Notice and Questionnaire to the Company
                  and the Trust and provided to the Trust and the Company such
                  information with respect to such Holder or the Registrable
                  Securities held by such Holder as is, in the reasonable
                  opinion of counsel to the Trust or the Company, required to
                  enable such Holder to use the Prospectus for resales of
                  Registrable Securities.

                           (2) Not less than 40 calendar days prior to the
                  Effective Time of the Shelf Registration Statement, the
                  Company or the Trust shall mail the Notice and Questionnaire
                  to each Holder. No Holder shall be entitled to be named as a
                  selling securityholder in the Shelf Registration Statement as
                  of the Effective Time, and no Holder shall be entitled to use
                  the Prospectus forming a part thereof for resales of
                  Registrable Securities at any time, unless such Holder has
                  returned a completed and signed Notice and Questionnaire to
                  the Company and the Trust and provided to the Trust and the
                  Company such information with respect to such Holder of the
                  Registrable Securities held by such Holder as is, in the
                  reasonable opinion of counsel to the Trust or the Company,
                  required to enable such Holder to use the Prospectus for
                  resales of Registrable Securities; provided, however, that
                  only Holders who have completed and returned the Notice and
                  Questionnaire and any such additional information requested of
                  such Holder to the Company or the Trust on or before the day
                  that is ten days prior to the Effective Time shall be entitled
                  to be named as a selling securityholder in the Shelf
                  Registration Statement as of the Effective Time.

                           (3) The term "Electing Holder" shall mean any Holder
                  that has returned a completed and signed Notice and
                  Questionnaire to the Company in accordance with Section
                  3(a)(1) or 3(a)(2) hereof and provided to the Trust and the
                  Company such information with respect to such Holder or the
                  Registrable Securities held by such Holder as is, in the
                  reasonable opinion of counsel to the Trust or the Company,
                  required to enable such Holder to use the Prospectus for
                  resales of Registrable Securities.

                  (b) The Company and the Trust shall furnish to each Electing
Holder, prior to the Effective Time, a copy of the Shelf Registration Statement
initially filed with the Commission, and shall furnish to such Holders copies of
each amendment thereto and each amendment or supplement, if any, to the
Prospectus included therein, and shall consider in good faith for inclusion in
each such document, at the Effective Time such comments as such Holders or their
counsel reasonably may propose.

                  (c) The Company and the Trust shall promptly take such action
as may be necessary so that (i) each of the Shelf Registration Statement and any
amendment thereto and the Prospectus forming part thereof and any amendment or
supplement thereto (and each report or other document incorporated therein by
reference in each case) complies in all material respects with the Securities
Act and the Rules and Regulations, (ii) each of the Shelf Registration Statement
and any amendment thereto does not, when it becomes effective, contain an untrue
statement of a material fact or omit to state a material fact required to be
stated therein or necessary to make the statements therein not misleading and
(iii) each of the Prospectus forming part of the Shelf Registration Statement,
and any amendment or supplement to such Prospectus, does not at any time during
the Effectiveness Period include an untrue statement of a material


                                        6

<PAGE>   7



fact or omit to state a material fact necessary in order to make the statements
therein, in the light of the circumstances under which they were made, not
misleading.

                  (d) (1) The Company shall promptly advise the Initial
Purchasers and, in the case of clause (i), the Electing Holders and, if
requested by the Initial Purchasers or any such Electing Holder, confirm such
advice in writing:

                           (i)  when the Shelf Registration Statement and any
         amendment thereto has been filed with the Commission and when the Shelf
         Registration Statement or any post effective amendment thereto has
         become effective; and

                           (ii) of any request by the Commission for amendments
         or supplements to the Shelf Registration Statement or the Prospectus
         included therein or for additional information.

                           (2) The Company shall promptly advise each Electing
         Holder of:

                           (i)   the issuance by the Commission of any stop
         order suspending the effectiveness of the Shelf Registration Statement
         or the initiation of any proceedings for such purpose;

                           (ii)  the receipt by the Company or the Trust of any
         notification with respect to the suspension of the qualification of the
         securities included in the Shelf Registration Statement for sale in any
         jurisdiction or the initiation of any proceeding for such purpose; and

                           (iii) the happening of any event that requires the
         making of any changes in the Shelf Registration Statement or the
         Prospectus included therein so that, as of such date, such Shelf
         Registration Statement and Prospectus do not contain an untrue
         statement of a material fact and do not omit to state a material fact
         required to be stated therein or necessary to make the statements
         therein (in the case of the Prospectus, in light of the circumstances
         under which they were made) not misleading (which advice shall be
         accompanied by an instruction to suspend the use of the Prospectus
         until the requisite changes have been made).

                  (e) The Company and the Trust shall each use its best efforts
to prevent the issuance, and if issued to obtain the withdrawal, of any stop
order suspending the effectiveness of the Shelf Registration Statement at the
earliest possible time.

                  (f) The Company and the Trust shall furnish to each Electing
Holder, without charge, at least one copy of the Shelf Registration Statement
and all post-effective amendments thereto, including financial statements and
schedules, and, if such Holder so requests in writing, all reports, other
documents and exhibits that are filed with or incorporated by reference in the
Shelf Registration Statement.

                  (g) The Company and the Trust shall, during the Effectiveness
Period, deliver to each Electing Holder, without charge, as many copies of the
Prospectus (including each preliminary Prospectus) included in the Shelf
Registration Statement and any amendment or supplement thereto as such Electing
Holder may reasonably request; and the Company and the Trust each consents
(except during the continuance of any event described in Section 3(d)(2)(iii)
above or during any Suspension Period) to the use of the Prospectus and any
amendment or supplement thereto by each of the Electing Holders in connection
with the offering and sale of the Registrable Securities covered by the
Prospectus and any amendment or supplement thereto during the Effectiveness
Period.



                                        7

<PAGE>   8



                  (h) Prior to any offering of Registrable Securities pursuant
to the Shelf Registration Statement, the Company and the Trust shall (1)
register or qualify or cooperate with the Electing Holders and their respective
counsel in connection with the registration or qualification of such Registrable
Securities for offer and sale under the securities or "blue sky" laws of such
jurisdictions within the United States as any Electing Holder may reasonably
request, (2) keep such registrations or qualifications in effect (subject to any
Suspension Period) and comply with such laws so as to permit the continuance of
offers and sales in such jurisdictions for so long as may be necessary to enable
any Electing Holder or underwriter, if any, to complete its distribution of
Registrable Securities pursuant to the Shelf Registration Statement, and (3)
take any and all other actions necessary or advisable to enable the disposition
in such jurisdictions of such Registrable Securities; provided, however, that in
no event shall the Company or the Trust be obligated to (i) qualify generally to
do business or as a foreign corporation or as a dealer in securities in any
jurisdiction where each would not otherwise be required to so qualify but for
this Section 3(h), (ii) file any general consent to service of process in any
jurisdiction where it is not as of the date hereof so subject or (iii) subject
itself to taxation in any jurisdiction where it is not otherwise so subject.

                  (i) Unless any Registrable Securities shall be in book-entry
only form, the Company and the Trust shall cooperate with the Electing Holders
to facilitate the timely preparation and delivery of certificates representing
Registrable Securities to be sold pursuant to the Shelf Registration Statement
free of any restrictive legends and in such permitted denominations and
registered in such names as Electing Holders may request in connection with the
sale of Registrable Securities pursuant to the Shelf Registration Statement.

                  (j) Upon the occurrence of any event contemplated by
paragraphs 2(b)(ii) and 3(d)(2)(iii) above, the Company and the Trust shall
promptly prepare a post-effective amendment or supplement to the Shelf
Registration Statement or the Prospectus, or any document incorporated therein
by reference, or file any other required document so that, as thereafter
delivered to Initial Purchasers of the Registrable Securities included therein,
the Prospectus will not include an untrue statement of a material fact or omit
to state any material fact necessary to make the statements therein, in the
light of the circumstances under which they were made, not misleading (except,
in each case, for an untrue statement of a material fact or omission of a
material fact made in reliance on and in conformity with written information
furnished to the Trust or the Company by or on behalf of any Electing Holders);
provided, however, if the proper officers of the Company determine in good faith
that disclosure in the Shelf Registration Statement of a material financing,
acquisition or other corporate transaction would not be in the best interests of
the Company and its stockholders, the Company and the Trust shall not be
required to prepare and file such amendment, supplement or document for such
period as such officers shall have determined in good faith is in the best
interests of the Company. Upon receipt of written notice from the Company or the
Trust of the occurrence of any event contemplated by paragraph 3(d)(2)(iii)
above or of any Suspension Period, each Holder shall forthwith discontinue
disposition of Registrable Securities until such Holder has received copies of
the supplemental or amended Prospectus required by this paragraph 3(j), or until
such Holder is advised by the Company or the Trust that the use of the
Prospectus may be resumed and, if so directed by the Company, such Holder shall
deliver to the Company (at the Company's expense) all copies then in such
Holder's possession of the Prospectus covering such Registrable Securities
current at the time of such notice.

                  (k) Not later than the effective date of any Shelf
Registration Statement hereunder, the Company and the Trust shall each provide a
CUSIP number for the Preferred Securities registered under such Shelf
Registration Statement; in the event of and at the time of any distribution of
the Convertible Debentures to Holders, the Company and the Trust shall provide a
CUSIP number for the Convertible


                                        8

<PAGE>   9



Debentures and provide the applicable trustee with certificates for such
Registrable Securities, in a form eligible for deposit with DTC.

                  (l) The Company and the Trust shall each use its best efforts
to comply with all applicable Rules and Regulations, and to make generally
available to its securityholders as soon as practicable after (i) the effective
date (as defined in Rule 158(c) under the Securities Act) of the Shelf
Registration Statement, (ii) the effective date of each post- effective
amendment to the Shelf Registration Statement, and (iii) the date of each filing
by the Company with the Commission of an Annual Report on Form 10-K that is
incorporated by reference in the Shelf Registration Statement, an earnings
statement of the Company and its subsidiaries complying with Section 11(a) of
the Securities Act and the rules and regulations of the Commission thereunder
(including, at the option of the Company, Rule 158).

                  (m) The Company and the Trust shall each use its best efforts
to cause the Indenture, the Trust Agreement and the Guarantee to be qualified
under the Trust Indenture Act in a timely manner.

                  (n) In the event of an underwritten offering conducted
pursuant to Section 6 hereof, the Company and the Trust shall, if requested,
promptly include or incorporate in a Prospectus supplement or post-effective
amendment to the Shelf Registration Statement such information as the Managing
Underwriters reasonably agree should be included therein and to which the
Company does not reasonably object and shall make all required filings of such
Prospectus supplement or post-effective amendment as soon as practicable after
it is notified of the matters to be included or incorporated in such Prospectus
supplement or post-effective amendment.

                  (o) The Company and the Trust shall enter into such customary
agreements (including an underwriting agreement in customary form in the event
of an underwritten offering conducted pursuant to Section 6 hereof) and take all
other appropriate actions in order to expedite and facilitate the registration
and disposition of the Registrable Securities, and in connection therewith, if
an underwriting agreement is entered into, cause the same to contain
indemnification provisions and procedures reasonably similar to those set forth
in Section 5 hereof with respect to all parties to be indemnified pursuant to
Section 5 hereof.

                  (p)  The Company and the Trust shall:

                           (i) (A) make available for inspection by Electing
         Holders, any underwriter participating in any disposition pursuant to
         such Shelf Registration Statement, and any attorney, accountant or
         other agent retained by such holders or any such underwriter all
         relevant financial and other records, pertinent corporate or other
         documents and properties of the Company, its subsidiaries and the
         Trust, and (B) cause the officers, directors, employees, trustees and
         agents of the Company and the Trust to supply all information requested
         by such Holders or any such underwriter, attorney, accountant or agent
         in connection with the Shelf Registration Statement, in each case, as
         is customary for similar due diligence examinations; provided, however,
         that each Electing Holder and its representatives and agents shall
         execute an agreement (in form reasonably acceptable to the Company)
         providing that all records, information and documents that are
         designated in writing by the Company and the Trust, in good faith, as
         confidential shall not be used for any other purpose and shall be kept
         confidential by such Holders and any such underwriter, attorney,
         accountant or agent, unless such disclosure is made in connection with
         a court proceeding or required by law, or such records, information or
         documents become available to the public generally or through a third
         party without an accompanying obligation of confidentiality; and
         provided further that, if the foregoing inspection and information
         gathering would, in the Company's reasonable judgment, disrupt the
         Company's conduct of its business, such inspection


                                        9

<PAGE>   10



         and information gathering shall be coordinated on behalf of the
         Electing Holders and the other parties entitled thereto by one counsel
         designated by and on behalf of Electing Holders and other parties (the
         fees and expenses of such counsel to be borne by such Electing Holders
         except to the extent set forth in Section 4);

                           (ii)  in connection with any underwritten offering
         conducted pursuant to Section 6 hereof, make such representations and
         warranties to the Holders participating in such underwritten offering
         and to the Managing Underwriters, in form, substance and scope as are
         customarily made by the Company and the Trust to underwriters in
         primary underwritten offerings of equity and convertible preferred and
         debt securities and covering matters including, but not limited to,
         those set forth in the Purchase Agreement;

                           (iii) in connection with any underwritten offering
         conducted pursuant to Section 6 hereof, obtain opinions of counsel
         (which counsel may be an employee of the Company) to the Company and
         the Trust (which counsel and opinions (in form, scope and substance)
         shall be reasonably satisfactory to the Managing Underwriters)
         addressed to each Holder participating in such underwritten offering
         and the underwriters, covering such matters as are customarily covered
         in opinions requested in underwritten offerings and such other matters
         as may be reasonably requested by such Holders and underwriters (it
         being agreed that the matters to be covered by such opinions shall
         include, without limitation, as of the date of the opinion and as of
         the Effective Time of the Shelf Registration Statement or most recent
         post-effective amendment thereto, as the case may be, a customary
         opinion on the absence from the Shelf Registration Statement and the
         Prospectus, including the documents incorporated by reference therein,
         of an untrue statement of a material fact or the omission of a material
         fact required to be stated therein or necessary to make the statements
         therein not misleading;

                           (iv)  in connection with any underwritten offering
         conducted pursuant to Section 6 hereof, obtain "cold comfort" letters
         and updates thereof from the independent public accountants of the
         Company and the Trust, addressed to each Holder participating in such
         underwritten offering (if such Holder has provided such letter,
         representations or documentation, if any, required for such "cold
         comfort" letter to be so addressed) and the underwriters, in customary
         form and covering matters of the type customarily covered in "cold
         comfort" letters in connection with primary underwritten offerings;

                           (v)   in connection with any underwritten offering
         conducted pursuant to Section 6 hereof, deliver such documents and
         certificates as may be reasonably requested by any Holders
         participating in such underwritten offering and the Managing
         Underwriters, if any, including, without limitation, certificates to
         evidence compliance with Section 3(j) hereof and with any conditions
         contained in the underwriting agreement or other agreements entered
         into by the Company and the Trust.

                  (q) The Company and the Trust will each use its best efforts
to cause the Company Common Stock issuable upon conversion of the Preferred
Securities to be listed for quotation on the New York Stock Exchange or other
stock exchange or trading system on which the Company Common Stock primarily
trades on or prior to the Effective Time of the Shelf Registration Statement
hereunder.

                  (r) The Company and the Trust shall each use reasonable best
efforts to take all other steps necessary to effect the registration, offering
and sale of the Registrable Securities covered by the Shelf Registration
Statement contemplated hereby.

                  (s) Upon receipt of written notice from the Company that a
Suspension Period is in effect, each Holder shall forthwith discontinue
disposition of Registrable Securities until such Holder has received copies of
the supplemental or amended Prospectus required by Section 3(j) hereof, or until
such Holder is advised in writing by the Company that the use of the Prospectus
may be resumed, and, if so directed by the Company, such Holder shall deliver to
the Company (at the Company's expense) all copies then in such Holder's
possession, other than permanent file copies, of the Prospectus covering such
Registrable Securities current at the time of receipt of such notice.

                  4. Registration Expenses. The Company and the Trust shall each
bear all fees and expenses customarily borne by issuers in a underwritten
secondary offering by selling securityholders or in an underwritten offering, as
the case may be, incurred in connection with the performance of its obligations
under Sections 2, 3 and 6 hereof. In addition, in the event of an underwritten
offering of Registrable Securities conducted pursuant to Section 6 hereof, or if
in any other event the Company requires that inspection and information
gathering be coordinated by counsel for the Electing Holders as provided in
Section 3(p)(i) hereof, the Company shall pay the fees and expenses of a single
counsel selected by the Electing Holders of not less than 25% of the Registrable
Securities to be included in such underwritten offering (or, in any such other
event, included in the Shelf Registration Statement) to represent them.

                  5.  Indemnification and Contribution.

                  (a) Indemnification by the Company. Upon the registration of
the Registrable Securities pursuant to Section 2 hereof, and in consideration of
the agreements of the Electing Holders and any underwriters, selling agents or
other securities professionals contained in Section 5(b) hereof, the Company and
the Trust, jointly and severally, agree to indemnify and hold harmless each
Electing Holder and each underwriter, selling agent or other securities
professional, if any, which facilitates the disposition of Registrable
Securities, and each of their respective officers and directors and each person
who controls such Electing Holder, underwriter, selling agent or other
securities professional within the meaning of Section 15 of the Securities Act
or Section 20 of the Exchange Act (each such person being sometimes referred to
as an "Indemnified Person") against any losses, claims, damages or liabilities,
joint or several, to which such Indemnified Person may become subject under the
Securities Act or otherwise, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based in whole
or in part upon any untrue statement or alleged untrue statement of any material
fact contained in any Shelf Registration Statement under which such Registrable
Securities are to be registered under the Securities Act, or any Prospectus
contained therein or any amendment or supplement thereto, or arise out of or are
based upon the omission or alleged omission to state therein a material fact
required to be stated therein or necessary to make the statements therein not
misleading, and will reimburse such Indemnified Person for any legal or other
expenses reasonably incurred by them in connection with investigating or
defending any such loss, claim, damage, liability or action as such expenses are
incurred; provided, however, that the Company and the Trust will not be liable
in any such case to the extent that any such loss, claim, damage or liability
arises out of or is based upon any untrue statement or alleged untrue statement
or omission or alleged omission made in such Shelf Registration Statement or
Prospectus, or amendment or supplement, in reliance upon and in conformity with
written information furnished to the Company or the Trust by such Indemnified
Person expressly for use therein.

                  The foregoing notwithstanding, the Trust and the Company shall
not be liable to the extent that such losses, claims, damages or liabilities
arise out of or are based upon an untrue statement or alleged untrue statement
or omission or alleged omission made in any Prospectus that is a preliminary
prospectus


                                       11

<PAGE>   12



if such Indemnified Person failed to send or deliver a copy of the Prospectus
(in the form it was first provided to such parties for confirmation of sales or
as amended or supplemented prior to such confirma tion of sales) to the Electing
Holders asserting such losses, claims, damages or liabilities on or prior to the
delivery of written confirmation of any sale of securities covered thereby to
such Electing Holder in any case where such delivery is required by the
Securities Act and a court of competent jurisdiction in a judgment not subject
to appeal or final review shall have determined that such Prospectus would have
corrected such untrue statement or omission.

                  In addition, the Trust and the Company shall not be liable to
the extent that any such losses, claims, damages or liabilities arise out of or
are based upon an untrue statement or alleged untrue statement or omission or
alleged omission in a Prospectus (x) if such untrue statement or omission or
alleged untrue statement or omission is corrected in an amendment or supplement
to such Prospectus and (y) having previously been furnished by or on behalf of
the Trust or the Company with copies of the Prospectus as amended or
supplemented, such Indemnified Person thereafter fails to deliver such
Prospectus as so amended or supplemented prior to or concurrently with the sale
to the person who purchased a Registrable Security from such Indemnified Person
and who is asserting such losses, claims, damages or liabilities.

                  (b) Indemnification by the Holders and any Agents and
Underwriters. Each Electing Holder agrees, as a consequence of the inclusion of
any of such Holder's Registrable Securities in such Shelf Registration
Statement, and each underwriter, selling agent or other securities professional,
if any, which facilitates the disposition of Registrable Securities shall agree,
as a consequence of facilitating such disposition of Registrable Securities,
severally and not jointly, to (i) indemnify and hold harmless each of the
Company and the Trust, its directors, trustees, agents and officers who sign any
Shelf Registration Statement and each person, if any, who controls the Company
or the Trust within the meaning of either Section 15 of the Securities Act or
Section 20 of the Exchange Act (collectively referred to as the "Indemnified
Party"), against any losses, claims, damages or liabilities to which the Company
or the Trust or such other persons may become subject, under the Securities Act
or otherwise, insofar as such losses, claims, damages or liabilities (or actions
in respect thereof) arise out of or are based upon any untrue statement or
alleged untrue statement of any material fact contained in such Shelf
Registration Statement or Prospectus, or any amendment or supplement, or arise
out of or are based upon the omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein not misleading, in each case to the extent, but only to the extent, that
such untrue statement or alleged untrue statement or omission or alleged
omission was made in reliance upon and in conformity with written information
furnished to the Company or the Trust by such Electing Holder, underwriter,
selling agent or other securities professional expressly for use therein, and
(ii) reimburse the Company and the Trust for any legal or other expenses
reasonably incurred by the Company and the Trust in connection with
investigating or defending any such loss, claim, damage, liability or action as
such expenses are incurred.

                  (c) Notices of Claims, Etc. If any action or proceeding
(including any governmental investigation or inquiry) shall be brought or
asserted against an Indemnified Person under subsection (a) or an Indemnified
Party under subsection (b) (collectively referred to as the "Indemnified
Holder") in respect of which indemnity may be sought, such Indemnified Holder
shall promptly notify the person against whom such indemnity may be sought (an
"Indemnifying Party") in writing, and the Indemnifying Party shall assume the
defense thereof, including the employment of counsel reasonably satisfactory to
such Indemnified Holder and the payment of all expenses in connection therewith;
but the omission so to notify the Indemnifying Party shall not relieve it from
any liability which it may have to any Indemnified Holder otherwise than under
this Section 5. Such Indemnified Holder shall have the right to employ separate
counsel in any such action and to participate in the defense thereof, but the
fees and expenses of such separate counsel shall be the expense of such
Indemnified Holder unless (i) the Indemnifying Party has


                                       12

<PAGE>   13



agreed to pay such fees and expenses, (ii) the Indemnifying Party shall have
failed to promptly assume the defense of such action or proceeding or has failed
to employ counsel reasonably satisfactory to such Indemnified Holder in any such
action or proceeding or (iii) the named parties to any such action or proceeding
(including any impended parties) include both such Indemnified Holder and the
Indemnifying Party, and such Indemnified Holder shall have been advised by
counsel that there may be one or more legal defenses available to such
Indemnified Holder that are different from or additional to those available to
the Indemnifying Party or that a conflict may exist between the Indemnified
Holder and the Indemnifying Party. If such Indemnified Holder notifies the
Indemnifying Party in writing that it elects to employ separate counsel at the
expense of the Indemnifying Party as permitted by the provisions of the
preceding sentence, the Indemnifying Party shall not have the right to assume
the defense of such action or proceeding on behalf of such Indemnified Holder.
The foregoing notwithstanding, the Indemnifying Party shall not be liable for
the fees and expenses of more than one legal counsel (in addition to any local
counsel) at any time for such Indemnified Holder and any other Indemnified
Holders (which firm shall be designated in writing by such Indemnified Holders)
in connection with any one such action or proceeding or separate but
substantially similar or related actions or proceedings in the same jurisdiction
arising out of the same general allegations or circumstances. The Indemnifying
Party shall not be liable for any settlement of any such action or proceeding
effected without the Indemnifying Party's prior written consent, and the
Indemnifying Party agrees to indemnify and hold harmless any Indemnified Holder
from and against any loss, damage, liability or expense by reason of any
settlement of any action effected with the written consent of the Indemnifying
Party. No Indemnifying Party shall, without the written consent of the
Indemnified Holder (which consent shall not be unreasonably withheld), effect
the settlement or compromise of, or consent to the entry of any judgment with
respect to, any pending or threatened action or claim in respect of which
indemnification or contribution may be sought hereunder (whether or not the
Indemnified Holder is an actual or potential party to such action or claim)
unless such settlement, compromise or judgment includes an unconditional release
of the Indemnified Holder from all liability arising out of such action or
claim.

                  (d) Contribution. In order to provide for just and equitable
contribution in circumstances in which the indemnity agreement provided for in
the preceding part of this Section 5 is for any reason held to be unavailable to
an indemnified Holder or is insufficient to hold harmless an indemnified party,
then each Indemnifying Party shall contribute to the damages paid by the
Indemnified Holder, and the Indemnifying Party shall contribute to the damages
paid by the Indemnified Holder provided, however, that no person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act) shall be entitled to contribution from any person who was not
guilty of such fraudulent misrepresenta tion. In determining the amount of
contribution to which the respective parties are entitled, there shall be
considered the relative fault of the Indemnifying Party and the Indemnified
Holder in connection with the statements or omissions which resulted in such
losses, claims, damages or liabilities (or actions in respect thereof), as well
as any other relevant equitable considerations. The relative fault of such
Indemnifying Party and Indemnified Holder shall be determined by reference to,
among other things, whether the untrue or alleged untrue statement of a material
fact or omission or alleged omission to state a material fact relates to
information supplied by such Indemnifying Party or by such Indemnified Holder,
and the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission. The parties agree
that it would not be just and equitable if contribution pursuant to this Section
5(d) were determined by pro rata or per capita allocation (even if the Electing
Holders or any underwriters, selling agents or other securities professionals or
all of them were treated as one entity for such purpose) or by any other method
of allocation which does not take account of the equitable considerations
referred to in this Section 5(d). The amount paid or payable by an indemnified
party as a result of the losses, claims, damages or liabilities (or actions in
respect thereof) referred to above shall be deemed to include any legal or other
fees or expenses reasonably incurred by such Indemnified Party in connection
with


                                       13

<PAGE>   14



investigating or defending any such action or claim. The obligations of the
Electing Holders and any underwriters, selling agents or other securities
professionals in this Section 5(d) to contribute shall be several in proportion
to the percentage of principal amount of Registrable Securities registered or
underwritten, as the case may be, by them and not joint.

                  (e) Notwithstanding any other provision of this Section 5, in
no event will any (i) Electing Holder be liable to any person under this Section
5 for any amounts in excess of the dollar amount of the proceeds to be received
by such holder from the sale of such holder's Registrable Securities (after
deducting any fees, discounts and commissions applicable thereto) pursuant to
any Shelf Registration Statement under which such Registrable Securities are to
be registered under the Securities Act and (ii) underwriter, selling agent or
other securities professional be liable to any person hereunder for any amounts
in excess of the discount, commission or other compensation payable to such
underwriter, selling agent or other securities professional with respect to the
Registrable Securities underwritten by it and distributed to the public,

                  (f) The obligations of the Company and the Trust under this
Section 5 shall be in addition to any liability which the Company and the Trust
may otherwise have to any Indemnified Person and the obligations of any
Indemnified Person under this Section 5 shall be in addition to any liability
which such Indemnified Person may otherwise have and shall extend, upon the same
terms and conditions, to each officer and director of the Company, each
Administrative Trustee of the Trust and to each person, if any, who controls the
Trust or the Company within the meaning of the Act. The remedies provided in
this Section 5 are not exclusive and shall not limit any rights or remedies
which may otherwise be available to an indemnified party at law or in equity.

                  6. Underwritten Offering. Any Electing Holder of Registrable
Securities who desires to do so may sell Registrable Securities (in whole or in
part) in an underwritten offering; provided that (i) the Holders of at least a
majority in aggregate principal amount of the outstanding Registrable Securities
shall request such an offering and (ii) at least such aggregate principal amount
of such Registrable Securities shall be included in such offering. Upon receipt
of such a request, the Company and the Trust shall provide all Holders of
Registrable Securities written notice of the request, which notice shall inform
such Holders that they have the opportunity to participate in the offering. In
any such underwritten offering, the investment banker or bankers and manager or
managers that will administer the offering will be selected by, and the
underwriting arrangements with respect thereto (including, subject to clause
(ii) above, the size of the offering) will be approved by the Holders of a
majority of the Registrable Securities to be included in such offering,
provided, however, that such investment bankers and managers and underwriting
arrangements must be reasonably satisfactory to the Company and the Trust. No
Holder may participate in any underwritten offering contemplated hereby unless
(a) such Holder agrees to sell such Holder's Registrable Securities to be
included in the underwritten offering in accordance with any approved
underwriting arrangements, (b) such Holder completes and executes all reasonable
questionnaires, powers of attorney, indemnities, underwriting agreements,
lock-up letters and other documents required under the terms of such approved
underwriting arrangements, and (c) if such Holder is not then an Electing
Holder, such Holder returns a completed and signed Notice and Questionnaire to
the Company and the Trust in accordance with Section 3(a)(2) hereof (but in no
event later than 10 days prior to commencement of the underwritten offering) and
provides to the Trust and the Company, in writing, any information with respect
to such Holder or the Registrable Securities held by such Holder as is, in the
reasonable opinion of counsel to the Trust or the Company, required under
applicable law to enable such Holder to use such Prospectus for resales of such
Registrable Securities, each within a reasonable amount of time before such
underwritten offering. The Holders participating in any underwritten offering
shall be responsible for any underwriting discounts and commissions and fees
and, subject to Section 4 hereof, expenses of their own


                                       14

<PAGE>   15



counsel. The Company and the Trust shall pay all expenses customarily borne by
issuers, including but not limited to filing fees, the fees and disbursements of
its counsel and independent public accountants and any printing expenses
incurred in connection with such underwritten offering. Notwithstanding the
foregoing or the provisions of Section 3(n) hereof, upon receipt of a request
from the Managing Underwriter or a representative of Holders of a majority of
the Registrable Securities to be included in an underwritten offering to prepare
and file an amendment or supplement to the Shelf Registration Statement and
Prospectus in connection with an underwritten offering, the Company and the
Trust may delay the filing of any such amendment or supplement for up to 90 days
if the Board of Directors of the Company shall have determined in good faith
that the Company has a bona fide business reason for such delay.

                  7.  Miscellaneous.

                  (a) Amendments and Waivers. This Agreement, including this
Section 7(a), may be amended, and waivers or consents to departures from the
provisions hereof may be given, only by a written instrument duly executed by
the Company and the Holders of a majority in aggregate principal amount of
Registrable Securities then outstanding. Each Holder of Registrable Securities
outstanding at the time of any such amendment, waiver or consent or thereafter
shall be bound by any amendment, waiver or consent effected pursuant to this
Section 7(a), whether or not any notice, writing or marking indicating such
amendment, waiver or consent appears on the Registrable Securities or is
delivered to such Holder.

                  (b) Notices. All notices and other communications provided for
or permitted hereunder shall be made in writing by hand-delivery, first-class
mail, telex, telecopier, or air courier guaranteeing overnight delivery:

                           (i)   if to a Holder, at such address set forth on
         the record books of the Company or the Trust, as the case may be;

                           (ii)  if to the Initial Purchasers, initially at the
         address set forth in the Purchase Agreement; and

                           (iii) if to the Company or the Trust, initially at
         its address set forth in the Purchase Agreement.

All such notices and communications shall be deemed to have duly given when
received.

                  The Initial Purchasers or the Company and the Trust by notice
to the other may designate additional or different addresses for subsequent
notices or communications.

                  (c) Parties in Interest. The parties to this Registration
Rights Agreement intend that all Holders of Registrable Securities shall be
entitled to receive the benefits of this Registration Rights Agreement and that
any Electing Holder shall be bound by the terms and provisions of this
Registration Rights Agreement by reason of such election with respect to the
Registrable Securities which are included in a Shelf Registration Statement. All
the terms and provisions of this Registration Rights Agreement shall be binding
upon, shall inure to the benefit of and shall be enforceable by the respective
successors and assigns of the parties hereto and any Holder from time to time of
the Registrable Securities to the aforesaid extent. In the event that any
transferee of any Holder of Registrable Securities shall acquire Registrable
Securities, in any manner, whether by gift, bequest, purchase, operation of law
or otherwise, such transferee shall, without any further writing or action of
any kind, be entitled to receive the benefits of and,


                                       15

<PAGE>   16



if an Electing Holder, be conclusively deemed to have agreed to be bound by and
to perform all of the terms and provisions of this Registration Rights Agreement
to the aforesaid extent.

                  (d) Counterparts. This Registration Rights Agreement may be
executed in any number of counterparts and by the parties hereto in separate
counterparts, each of which when so executed shall be deemed to be an original
and all of which taken together shall constitute one and the same agreement.

                  (e) Headings. The headings in this Registration Rights
Agreement are for convenience of reference only and shall not limit or otherwise
affect the meaning hereof.

                  (f) Governing Law. This Registration Rights Agreement shall be
governed by and construed in accordance with the laws of the State of New York,
without giving effect to any provisions relating to conflicts of laws.

                  (g) Severability. In the event that any one or more of the
provisions contained herein, or the application thereof in any circumstances, is
held invalid, illegal or unenforceable in any respect for any reason, the
validity, legality and enforceability of any such provision in every other
respect and of the remaining provisions hereof shall not be in any way impaired
or affected thereby, it being intended that all of the rights and privileges of
the parties hereto shall be enforceable to the fullest extent permitted by law.

                  8. No Liability of Property Trustee, Delaware Trustee or
Guarantee Trustee.

                  It is expressly understood and agreed by the parties hereto
that (a) each of the representations, undertakings and agreements herein made on
the part of the Trust is made and intended not as representations, warranties,
covenants, undertakings and agreements of any Trustee of the Trust, including,
without limitation, Chase Bank of Texas, National Association as Guarantee
Trustee or Property Trustee or Chase Manhattan Bank Delaware as Delaware
Trustee, in their individual capacity, but is made and intended for the purpose
of binding only the Trust, and (b) under no circumstances shall any Trustee,
including Chase Bank of Texas, National Association as Guarantee Trustee or
Property Trustee or Chase Manhattan Bank Delaware as Delaware Trustee be
personally liable for any breach or failure of any obligation, representation,
warranty, or covenant made or undertaken by the Trust under this Agreement
except if such breach or failure is due to any gross negligence or wilful
misconduct of the Trustee.

the Guarantor shall not (except to the extent required by mandatory provisions
of law) be entitled to enforce or exercise any rights that it may acquire by way

SECTION 3.1.      Limitation of Transactions

                  So long as any Common Securities remain outstanding, if (i)
the Company has exercised its option to defer interest payments on the
Convertible Debentures by extending the interest payment period and such
extension shall be continuing, (ii) if there shall have occurred any Event of
Default under this Common Securities Guarantee, or (iii) there shall have
occurred and be continuing any event that, with the giving of notice or the
lapse of time or both, would constitute an Indenture Event of Default, then the
Guarantor has agreed (a) not to declare or pay dividends on, make a
distribution with respect to, or redeem, purchase, acquire or make a liquidation
payment with respect to, any of its capital stock (other than (i) purchases or
acquisitions of shares of common stock in connection with the satisfaction by
the Guarantor of its obligations under any employee benefit plans or the
satisfaction by the Guarantor of its obligations pursuant to any contract or
security requiring the Guarantor to purchase shares of common stock, (ii) as a
result of a reclassification of the Guarantor's capital stock or the exchange or
conversion of one class or series of the Guarantor's capital stock for another
class or series of the Guarantor's capital stock or (iii) the purchase of
fractional interests in shares of the Guarantor's capital stock pursuant to the
conversion or exchange provisions of such capital stock or the security being
converted or exchanged (or make any guarantee payments with respect to the
foregoing), (b) not to make any payment of interest, principal or premium, if
any, on or repay, repurchase or redeem any debt securities of the Company that
rank pari passu with or junior to the Convertible Debentures (except by
conversion into or exchange for shares of its capital stock), and 


                                        6

(c) not to make any guarantee payments with respect to the foregoing (other than
pursuant to this Common Securities Guarantee).

SECTION 3.2.      Ranking

                  (a)      This Common Securities Guarantee will constitute an
unsecured obligation of the Guarantor and will rank (i) subordinate and junior
to all other liabilities of the Guarantor except any liabilities that may be
pari passu expressly by their terms, (ii) pari passu with the most senior
preferred stock issued from time to time by the Guarantor and with any guarantee
now or hereafter entered into by the Guarantor in respect of any preferred or
preference stock or preferred securities of any affiliate of the Guarantor and
(iii) senior to the Guarantor's common stock.

                  (b)      The holders of any obligations of the Guarantor that
are senior in priority to the obligations under this Common Securities Guarantee
will be entitled to all of the rights inuring to the holders of "Senior
Indebtedness" under Article 12 of the Indenture, and the holders of the
Preferred Securities will be subject to all of the terms and conditions of such
Article 12 with respect to any claims or rights hereunder with the same effect

Central Parking Corporation
2401 21st Avenue South, Suite 200
Nashville, Tennessee 37212

Ladies and Gentlemen:

         We have acted as legal counsel to Central Parking Corporation, (the
"Company") and Central Parking Finance Trust (the "Trust") in connection with
the preparation of a Registration Statement on Form S-3 under the Securities Act
of 1933, as amended ("Registration Statement"), relating to up to 4,400,000
shares of the Trust's convertible trust issued preferred stock, (the "Preferred
Securities"), the Company's common stock, $0.01 par value per share (the "Common
Stock") into which the Preferred Securities is convertible, as well as 69,473
shares of Common Stock to be sold by certain shareholders of the Trust and/or
the Company (the "Selling Shareholders"), as well as the $113,402,050 principal
amount of 5 1/4% Convertible Subordinated Debentures (the "Debentures") of the
Company which may be distributed, under certain circumstances, to the holders of
the Preferred Securities.

         We have examined and are familiar with the Amended and Restated Charter
and the Bylaws of the Company, the Amended and Restated Declaration of Trust of
the Trust, the indenture between the Company and Chase Bank of Texas as Trustee
dated March 18, 1998 (the "Indenture") and the various corporate records and
proceedings relating to the organization of the Company, the Trust and the
filing of the Registration Statement. We have also examined such other documents
and proceedings as we have considered necessary for the purpose of this opinion.

         Based on the foregoing it is our opinion that (i) the Preferred
Securities and the Common Stock to be sold by the Selling Shareholders are
validly issued, fully paid and non assessable; (ii) the Debentures issued
pursuant to the Indenture are legally issued, fully paid, non-assessable binding
obligations of the Company; and (iii) the shares to be issued by the Company
upon conversion of the Debentures and the Preferred Securities will, when issued
and delivered in the manner and on the terms described in the Amended and
Restated Declaration of Trust and the Indenture, be legally issued, fully paid,
and non-assessable.

         We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement, and with such state securities administrators as may
require such opinion of counsel for the registration of the Shares, and the
reference to this firm under the heading "Legal Matters" in the Prospectus.

                                       Very truly yours,

                                       Harwell Howard Hyne

Re: Central Parking Finance Trust;
Central Parking Corporation
Offering of 5.25% Convertible Trust Issued
Preferred Securities

Ladies and Gentlemen:

         We have acted as a special tax counsel for Central Parking Corporation,
a Tennessee corporation (the "Company"), and Central Parking Finance Trust, a
statutory business trust organized under the Business Trust Act of the State of
Delaware (Del. Code Ann., tit. 12, ss.3810) (the "Trust"), in connection with
the offering of (i) aggregate amount of 4,000,000 (4,400,000 if the Initial
Purchasers' over-allotments option is exercised in full), 5.25% Convertible
Trust Issued Preferred Securities (the "Preferred Securities") (liquidation
amount of $25 per Preferred Security) of the Trust, representing undivided
interests in the assets of the Trust; and (ii) $ 103,092,775 ($113,402,050 if
the Initial Purchasers' over-allotments option is exercised in full) aggregate
principal amount of 5.25% Convertible Subordinated Debentures due April 1st,
2028 of the Company (the "Convertible Debentures") to the Trust.

         The Preferred Securities are guaranteed (the " Preferred Securities
Guarantee") by the Company with respect to the payment of distributions and
payments upon liquidation,



<PAGE>   2



redemption and otherwise pursuant to, and to the extent set forth in, the
Preferred Securities Guarantee Agreement (" Preferred Securities Guarantee
Agreement"), between the Company and Chase Bank of Texas, National Association,
a Texas banking corporation, as a trustee for the benefit of the holders of the
Convertible Preferred Securities.

         In connection with the issuance of the Preferred Securities, the Trust
is also issuing 123,711 (136,082 if the Initial Purchasers' over-allotments
option is exercised in full) of its convertible common securities (liquidation
amount of $25 per common security) (the " Common Securities"), representing
undivided beneficial interests in the assets of the Trust. The Common Securities
are also guaranteed by the Company with respect to the payment of distributions
and payments upon liquidation, redemption and otherwise pursuant to, and to the
extent set forth in, the Common Securities Guarantee Agreement ("Common
Securities Guarantee Agreement"), between the Company and Chase Bank of Texas,
National Association, a Texas banking corporation, as a trustee for the benefit
of the holders of the Common Securities.

         The Preferred Securities and the Common Securities are being issued
pursuant to the Amended and Restated Deceleration of Trust (the "Trust
Agreement"), dated March 18, 1998, among the Company, as a trust sponsor and as
the issuer of the Convertible Debentures to be held by the Property Trustee (as
defined below) of the Trust, Chase Manhattan Bank Delaware, as Delaware trustee,
Chase Bank of Texas, National Association, a Texas banking corporation as
property trustee (the "Property Trustee") and Monroe J. Carell, Jr., James H.
Bond and Andrew M. Paalborg, as administrative trustees.

         The entire proceeds from the sale of the Preferred Securities and the
Common Securities are to be used by the Trust to purchase the Convertible
Debentures. The Convertible Debentures are to be issued pursuant to an Indenture
(the "Indenture") between the Company and Chase Bank of Texas, National
Association, as trustee (the "Indenture Trustee").

         In connection with this opinion, we have examined originals or copies,
certified or otherwise identified to our satisfaction, of (i) the Offering
Circular dated March, 13, 1998 for the Preferred Securities ("Offering
Circular"); (ii) the certificate of trust of the Trust (the "Certificate of
Trust") filed by the Trust with the Secretary of State of the State of Delaware
on February 18, 1998; (iii) the form of Trust Agreement (including the
designations of the terms of the Preferred Securities annexed thereto); (iv) the
form of the Preferred Securities Guarantee Agreement, (v) the form of the
Indenture; (vi) the form of Convertible Debentures and a specimen certificate
thereof; (vii) a specimen certificate representing the Common Securities; (viii)
the form of the purchase agreement proposed to be entered into among the
Company, the Trust and Bear, Stearns & Co. Inc., J.C. Bradford & Co., William
Blair & Company LLC, NationsBanc Montgomery Securities LLC, SunTrust Equitable
Securities (the "Purchase Agreement"); (ix) the form of the Preferred Securities
and a specimen certificate thereof; and (x) the officer's certificate of the
Company dated March 18, 1998. Furthermore, we have relied upon certain
statements and representations made by officers of the Company. We have also
examined originals or copies, certified or otherwise identified to our
satisfaction, of such records of the Trust and the Company and such other
documents, certificates and records as we have deemed necessary or appropriate
as a basis for the opinions set forth herein.



<PAGE>   3



         In rendering our opinion, we have participated in the preparation of
the Offering Circular. Our opinion is conditioned on, among other things, the
initial and continuing accuracy of the facts, information, covenants and
representations set forth in the documents referred to above, and the statements
and representations made by the Company and the Trust. In our examination, we
have assumed the genuineness of all signatures, the legal capacity of all
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
copies. We also have assumed that the Trust Agreement, the Preferred Securities,
the Guarantee Agreement, the Convertible Debentures, and the Indenture will be
executed in substantially the form reviewed by us and that the transactions
related to the issuance of the Preferred Securities, the Common Securities, the
Convertible Debentures and the Conversion Shares will be consummated in the
manner contemplated by the Offering Circular.

         In rendering our opinion, we have considered the current provisions of
the Internal Revenue Code of 1986, as amended (the "Code"), Treasury regulations
(proposed, temporary and final) promulgated thereunder, judicial decisions and
Internal Revenue Service rulings, all of which are subject to change, which
changes may be retroactively applied. A change in the authorities upon which our
opinion is based could affect our conclusions. There can be no assurances,
moreover, that any of the opinions expressed herein will be accepted by the
Internal Revenue Service or, if challenged, by a court.

         Based solely upon the foregoing, we are of the opinion that under
current United States federal income tax law:

         (1) The Trust will be classified as a grantor trust and not as an
association taxable as a corporation for United States federal income tax
purposes.


         (2) Although the discussion set forth in the Offering Circular under
the caption "UNITED STATES FEDERAL INCOME TAXATION" does not purport to discuss
all possible United State federal income tax consequences of the purchase,
ownership, conversion and disposition of Preferred Securities, such discussion,
although general in nature, constitutes in all material respects, a fair and
accurate summary under current law of certain of the material United States
federal income tax consequences of the purchase, ownership, conversion and
disposition of Preferred Securities by a holder who purchased such Preferred
Securities upon original issuance. The United State federal income tax
consequences of an investment in the Preferred Securities by a United States
investor will depend upon that holder's particular situation, and we express no
opinion as to the completeness of the discussion set forth in "UNITED STATES
FEDERAL INCOME TAXATION" as applied to any particular holder.


                  Except as set forth above, we express no opinion to any party
as to the tax consequences, whether federal, state, local or foreign, of the
issuance of the Convertible Debentures, the Preferred Securities, the Common
Securities or of any transactions related to or contemplated by such issuance.
This opinion is solely for your benefit in connection with the

Offering except as set forth below, is not to be used, circulated, quoted or
otherwise referred to for any purpose without our prior written consent. We
hereby consent to the use of our name under the heading "Legal Matters" in the
Offering Circular. In giving this consent, we do not thereby admit that we are
within the category of persons whose consent is required under Section 7 of the
Act or the rules and regulations of the Commission promulgated thereunder. This
opinion is expressed as of the date hereof unless otherwise expressly stated,
and we disclaim any undertaking to advise you of any subsequent changes of the
facts stated or assumed herein or any subsequent changes in applicable law.
