determined at the time of the offering. The Common Stock, Preferred Stock, Debt
Securities and Warrants are collectively called the "Securities."
 
    The Securities offered pursuant to this Prospectus may be issued in one or
more series or issuances and will have an aggregate public offering price of up
to $800,000,000 (or the equivalent thereof, based on the applicable exchange

(2) Earnings were insufficient to cover fixed charges and fixed charges and
    preferred stock dividends by $79,384,000 and $80,463,000, respectively.
 
     For purposes of calculating the ratio of earnings to fixed charges and the
ratio of earnings to fixed charges and preferred stock dividends, earnings
consist of income before taxes and fixed charges (exclusive of preferred stock
dividends). For purposes of calculating both ratios, fixed charges include
interest expense and capitalized interest.
 
                          DESCRIPTION OF CAPITAL STOCK
 
     Pursuant to Allied's Certificate of Incorporation, as amended (the
"Certificate"), the authorized capital stock of Allied consists of 200,000,000
shares of Common Stock and 10,000,000 shares of Preferred Stock, of which
100,000 shares are designated as 7% Cumulative Convertible Preferred Stock (the
"7% Preferred Stock"). The following description of certain of Allied's capital
stock is a summary, does not purport to be complete or to give effect to
applicable statutory or common law and is subject in all respects to the
applicable provisions of the Certificate and the information herein is qualified
in its entirety by this reference.
 
COMMON STOCK
 
     At March 31, 1997, Allied had outstanding 75,813,070 shares of Common
Stock. Holders of Common Stock are entitled to one vote per share in the
election of directors and on all other matters on which the stockholders are
entitled or permitted to vote. Holders of Common Stock are not entitled to
cumulative voting rights. Therefore, holders of a majority of the shares voting
for the election of directors can elect all the directors. Subject to the terms
of any outstanding series of preferred stock, the holders of Common Stock are
entitled to dividends in such amounts and at such times as may be declared by
Allied's Board of Directors out of funds legally available therefor. On
liquidation or dissolution, holders of Common Stock are entitled to share
ratably in all net assets available for distribution to stockholders after
payment of any liquidation preferences to holders of Preferred Stock. Holders of
Common Stock have no redemption, conversion or preemptive rights. The Common
Stock is listed on the Nasdaq National Market tier of Nasdaq under the symbol
"AWIN."
 
PREFERRED STOCK
 
     The particular terms of any series of Preferred Stock offered hereby will
be set forth in the Prospectus Supplement relating thereto. The rights,
preferences, privileges and restrictions, including dividend rights, voting
rights, terms of redemption, retirement and sinking fund provisions and
liquidation preferences, if any, of the Preferred Stock of each series will be
fixed or designated pursuant to a certificate of designation adopted by the
Board of Directors or a duly authorized committee thereof. The terms, if any, on
which shares of any series of Preferred Stock are convertible or exchangeable
into Common Stock will also be set forth in the
 
                                        4
<PAGE>   6
 
Prospectus Supplement relating thereto. Such terms may include provisions for
conversion or exchange, either mandatory, at the option of the holder, or at the
option of Allied, in which case the number of shares of Common Stock to be
received by the holders of Preferred Stock would be calculated as of a time and
in the manner stated in the applicable Prospectus Supplement. The description of
the terms of a particular series of Preferred Stock that will be set forth in
the applicable Prospectus Supplement does not purport to be complete and is
qualified in its entirety by reference to the certificate of designation
relating to such series.
 
     7% Preferred Stock.  At March 31, 1997, Allied had outstanding 9,496 shares
of 7% Preferred Stock. Pursuant to the 7% Preferred Certificate of Designation,
Preferences, Rights and Limitations (the "7% Certificate of Designation"), the
7% Preferred Stock has no voting rights. The 7% Preferred Stock has a
liquidation preference of $1,000 per share, subject to adjustment. Dividends on
the 7% Preferred Stock are $70.00 per annum and are cumulative and payable
quarterly. The first 9,963 shares of 7% Preferred Stock are currently
convertible into shares of the Common Stock at the rate of $7.00 (142.857 shares
of Common Stock per share of 7% Preferred Stock) per share of Common Stock,
subject to adjustment in the event of stock splits, dividends and
recapitalizations involving the Common Stock. The remaining shares of 7%
Preferred Stock will be convertible into shares of Common Stock at 130% of the
market price (as defined).
 
     Under the 7% Certificate of Designation, Allied may redeem any part, on a
pro rata basis, of the 7% Preferred Stock at any time.
 
     Other Designated Preferred Stock.  Allied currently has 800,000 shares of
preferred stock designated as Series C Convertible Preferred Stock, 267,000
shares of Preferred Stock designated as Series D Convertible Preferred Stock,
30,000 shares of Preferred Stock designated as 9% Cumulative Convertible
Preferred Stock and 20,000 shares of Preferred Stock designated as $90
Cumulative Convertible Preferred Stock, none of which is outstanding.
 
SPECIAL PROVISIONS OF THE CERTIFICATE OF INCORPORATION AND DELAWARE LAW
 
     The provisions of the Certificate and Allied's Bylaws, as amended (the
"Bylaws"), summarized in the succeeding paragraphs may be deemed to have an
anti-takeover effect or may delay, defer or prevent a tender offer or takeover
attempt that a stockholder might consider in such stockholder's best interest,
including those attempts that might result in a premium over the market price
for the shares held by a stockholder.
 
     Pursuant to the Certificate, the Board of Directors may by resolution
establish one or more series of preferred stock, having such number of shares,
designation, relative voting rights, dividend rates, liquidation or other
rights, preferences and limitations as may be fixed by the Board of Directors
without any further stockholder approval. Such rights, preferences, privileges
and limitations as may be established could have the effect of impeding or
discouraging the acquisition of control of Allied.
 
     The Bylaws provide that stockholders' nominations for the Board of
Directors and proposals for other business to be transacted at stockholders'
meetings must be timely received by Allied and must comply with specified form
and content requirements. The Bylaws also provide that special meetings of
stockholders may be called only by the Board or by a specifically authorized
committee of the Board. The Certificate and the Bylaws provide that the Bylaws
may be altered, amended or repealed by the Board of Directors.
 
     Limitation of Director Liability.  Section 102(b)(7) of the Delaware
General Corporation Law ("Section 102(b)") authorizes corporations to limit or
to eliminate the personal liability of directors to corporations and their
stockholders for monetary damages for breach of directors' fiduciary duty of
care. Although Section 102(b) does not change directors' duty of care, it
enables corporations to limit available relief to equitable remedies such as
injunction or rescission. The Certificate limits the liability of directors to
Allied or its stockholders to the fullest extent permitted by Section 102(b).
Specifically, directors of Allied will not be personally liable for monetary
damages for breach of a director's fiduciary duty as a director, except for
liability (i) for any breach of the director's duty of loyalty to Allied or its
stockholders, (ii) for acts or omissions not in good faith, or which involve
intentional misconduct or a knowing violation of law, (iii) for unlawful
payments of dividends or unlawful stock repurchases or redemptions as provided
in Section 174 of
 
                                        5
<PAGE>   7
 
the Delaware General Corporation Law, or (iv) for any transaction from which the
director derived an improper personal benefit.
 
     Indemnification.  To the maximum extent permitted by law, the Certificate
and the Bylaws provide for mandatory indemnification of directors, officers,
employees and agents of Allied against all expenses, liabilities and losses to
which they may become subject or which they may incur as a result of being or
having been a director, officer, employee or agent of Allied. In addition,
Allied must advance or reimburse directors and officers and may advance or
reimburse employees and agents for expenses incurred by them in connection with
indemnifiable claims.
 
     Insofar as indemnification for liabilities arising out of the Securities
Act may be permitted to directors, officers and controlling persons of Allied
pursuant to the foregoing provisions, Allied has been informed that in the
opinion of the Commission such indemnification is against public policy as
expressed in the Securities Act and is therefore unenforceable.
 
     Delaware Anti-Takeover Law.  Section 203 of the Delaware General
Corporation Law ("Section 203") generally provides that a stockholder, and the
affiliates and associates of such stockholder, acquiring more than 15% of the
outstanding voting stock of a corporation subject to the statute (an "Interested
Stockholder") but less than 85% of such stock may not engage in certain Business
Combinations (as defined in Section 203) in the corporation for a period of
three years after the date on which the stockholder became an Interested
Stockholder unless (i) prior to such date, the corporation's board of directors
approved either the Business Combination or the transaction in which the
stockholder became an Interested Stockholder or (ii) the Business Combination is
approved by the corporation's board of directors and authorized at a
stockholders' meeting by a vote of at least two-thirds of the corporation's
outstanding voting stock not owned by the Interested Stockholder. Under Section
203, these restrictions will not apply to certain Business Combinations proposed
by an Interested Stockholder following the earlier of the announcement or
notification of one of certain extraordinary transactions involving the
corporation and a person who was not an Interested Stockholder during the
previous three years or who became an Interested Stockholder with the approval
of the corporation's board of directors, if such extraordinary transaction is
approved or not opposed by a majority of the directors who were directors prior
to such person becoming an Interested Stockholder during the previous three
years or were recommended for election or elected to succeed such directors by a
majority of such directors.
 
     Section 203 defines the term Business Combination to encompass a wide
variety of transactions with or caused by an Interested Stockholder, including
transactions in which the Interested Stockholder receives or could receive a
benefit on other than a pro rata basis with other stockholders, such as mergers,
certain asset sales, certain issuances of additional shares to the Interested
Stockholder, transactions with the corporation which increase the proportionate
interest in the corporation directly or indirectly owned by the Interested
Stockholder or transactions in which the Interested Stockholder receives certain
other benefits.
 
     The provisions of Section 203, coupled with the Board's authority to issue
preferred stock without further stockholder action, could delay or frustrate the
removal of incumbent directors or a change in control of Allied. The provisions
also could discourage, impede or prevent a merger, tender offer or proxy
contest, even if such event would be favorable to the interests of stockholders.
Allied's stockholders, by adopting an amendment to the Certificate, may elect
not to be governed by Section 203 effective 12 months after such adoption.
Neither the Certificate nor the Bylaws exclude Allied from the restrictions
imposed by Section 203.
 
TRANSFER AGENT
 
     The transfer agent and registrar for the Common Stock is American Stock
Transfer & Trust Company.

terms of the AWNA Debt Securities sets forth certain general terms and
provisions of such Debt Securities. To the extent any terms described below
apply specifically (i) to the Allied Debt Securities or the AWNA Debt

     The Senior Allied Debt Securities offered hereby are to be issued in one or
more series under the Indenture dated as of               , 1997, as amended or

Securities offered hereby are to be issued in one or more series under the

together with the Senior Allied Indenture, the "Senior Indentures") between
AWNA, Allied, as guarantor, the Subsidiary Guarantors and First Bank National
Association, as trustee (the "Senior AWNA Trustee" and, together with the Senior
Allied Trustee, the "Senior Trustees"). The Senior Subordinated AWNA Debt
Securities offered hereby are to be issued in one or more series under the
Indenture dated as of               , 1997, as amended or supplemented from time
to time (as so amended or supplemented, the "Senior Subordinated AWNA Indenture"
and, together with the Senior Subordinated Allied Indenture, the "Senior
Subordinated Indentures") between AWNA, Allied, as guarantor, the Subsidiary
Guarantors and First Bank National Association, as trustee (the "Senior
Subordinated AWNA Trustee" and, together with the Senior Subordinated Allied
Trustee, the "Senior Subordinated Trustees"). The Senior Indentures and the
Senior Subordinated Indentures are referred to collectively herein as the
"Indentures" and the Senior Trustees and the Senior Subordinated Trustees are
referred to collectively herein as the "Trustees." Copies of the Indentures have
been filed as exhibits to the Registration Statement of which this Prospectus
forms a part.
 
     The terms of the Debt Securities include those stated in the applicable
Indenture and those made a part of the applicable Indenture by reference to the
Trust Indenture Act of 1939, as amended (the "TIA"). The Debt Securities are
subject to all such terms and the holders of Debt Securities are referred to the
applicable Indenture and the TIA for a statement of such terms.
 
     The following summaries of certain provisions of each Indenture and the
Debt Securities are not complete and are qualified in their entirety by
reference to the provisions of each Indenture, including the definitions of
capitalized terms used herein without definition. Numerical references in
parentheses are to sections in the applicable Indenture and unless otherwise
indicated capitalized terms have the meanings given them in the applicable
Indenture.
 
GENERAL
 
     Unless otherwise specified in a Prospectus Supplement, (i) the Senior Debt
Securities, when issued, will rank pari passu in right of payment with all other
unsubordinated obligations of Allied or AWNA, as the case
 
                                        7
<PAGE>   9
 
may be, and will rank senior in right of payment to all subordinated obligations
of Allied or AWNA, as the case may be, (ii) the Senior Guarantees, when issued,
will rank pari passu in right of payment with all other unsubordinated
obligations of the Guarantors, and will rank senior in right of payment to all
subordinated obligations of the Guarantors, (iii) the Senior Subordinated Debt
Securities, when issued, will be subordinate in right of payment to the prior
payment in full of all Senior Debt (as defined herein) of Allied or AWNA, as the
case may be, including all Senior Debt Securities of Allied or AWNA, as the case
may be, and will rank pari passu in right of payment with all other senior
subordinated obligations of Allied or AWNA, as the case may be, and (iv) the
Senior Subordinated Guarantees, when issued, will be subordinate in right of
payment to the prior payment in full of all Senior Debt of Allied, including, in
the case of Allied, all Senior Allied Debt Securities, and will rank pari passu
in right of payment with all other senior subordinated obligations of the
Guarantors. Holders of secured obligations of Allied, AWNA and the Guarantors,
including secured Allied Debt Securities, secured AWNA Debt Securities and
secured Guarantees, respectively, will, however, have claims that are prior to
the claims of holders of unsecured Allied Debt Securities, AWNA Debt Securities
and Guarantees, respectively with respect to the assets securing such secured
obligations. Allied conducts its operations through AWNA, which is subject,
under certain of its debt instruments, to certain restrictions on its ability to
pay funds to Allied. All Allied Debt Securities and Guarantees of Allied will
effectively be subordinate in right of payment to the prior payment in full of
all indebtedness of Allied's subsidiaries and all other obligations and other
liabilities, including trade payables, of Allied's subsidiaries, including all
AWNA Debt Securities.
 
     The Indentures do not limit the aggregate amount of Debt Securities which
may be issued thereunder. Except as otherwise provided in the applicable
Prospectus Supplement, the Indentures, as they apply to any series of Debt
Securities, do not limit the incurrence or issuance of other secured or
unsecured debt of Allied or AWNA, as the case may be, whether under any of the
Indentures, or any other indenture that Allied or AWNA, as the case may be, may
enter into in the future or otherwise. See "-- Subordination under the Senior
Subordinated Indentures" and the Prospectus Supplement relating to any offering
of Senior Subordinated Securities.
 
     The Debt Securities will be issuable in one or more series pursuant to an
indenture supplement to the applicable Indenture or a resolution of Allied's, or
AWNA's, as the case may be, Board of Directors or a committee thereof. (Section
2.1 of each Indenture)
 
     Reference is made to the applicable Prospectus Supplement which will
accompany this Prospectus for a description of the specific series of Debt
Securities being offered thereby, including: (1) the title of such Debt
Securities; (2) any limit upon the aggregate principal amount of such Debt
Securities; (3) the date or dates on which the principal of and premium, if any,
on such Debt Securities will mature or the method of determining such date or
dates; (4) the rate or rates (which may be fixed or variable) at which such Debt
Securities will bear interest, if any, and the method of calculating such rate
or rates; (5) the date or dates from which interest, if any, will accrue or the
method by which such date or dates will be determined; (6) the date or dates on
which interest, if any, will be payable and the record date or dates therefor;
(7) the place or places where principal of, premium, if any, and interest, if
any, on such Debt Securities will be payable or at which Debt Securities may be
surrendered for registration of transfer or exchange; (8) the period or periods
within which, the price or prices at which, if other than in United States
dollars, the currency or currencies (including currency unit or units) in which,
and the other terms and conditions upon which, such Debt Securities may be
redeemed, in whole or in part, at the option of Allied or AWNA, as the case may
be, (9) the obligation, if any, of Allied or AWNA, as the case may be, to redeem
or purchase such Debt Securities pursuant to any sinking fund or analogous
provisions or upon the happening of a specified event or at the option of a
holder thereof and the period or periods within which, the price or prices at
which, if other than in United States dollars, the currency or currencies
(including currency unit or units) in which, and the other terms and conditions
upon which, such Debt Securities shall be redeemed or purchased, in whole or in
part, pursuant to such obligation; (10) the denominations in which such Debt
Securities are authorized to be issued; (11) the currency or currency unit in
which Debt Securities may be denominated and/or the currency or currencies
(including currency unit or units) in which principal of, premium, if any, and
interest, if any, on such Debt Securities will be payable and whether Allied or
AWNA, as the case may be, or the holders of any such Debt Securities may
 
                                        8
<PAGE>   10
 
elect to receive payments in respect of such Debt Securities in a currency or
currency unit other than that in which such Debt Securities are stated to be
payable; (12) if the amount of principal of, or any premium or interest on, any
of such Debt Securities may be determined with reference to an index or pursuant
to a formula or other method, the manner in which such amounts will be
determined; (13) if other than the principal amount thereof, the portion of the
principal amount of such Debt Securities which will be payable upon declaration
of the acceleration of the maturity thereof or the method by which such portion
shall be determined; (14) provisions, if any, granting special rights to the
holders of Debt Securities upon the occurrence of such events as may be
specified; (15) any addition to, or modification or deletion of, any Event of
Default or any covenant of Allied, or AWNA or any Guarantor, as the case may be,

circumstances under which Allied, or AWNA or any Guarantor, as the case may be,
will pay additional amounts on the Debt Securities held by non-U.S. persons in
respect of taxes, assessments or similar charges; (17) whether the Debt
Securities will be issued in registered or bearer form or both; (18) the
application, if any, of such means of defeasance or covenant defeasance as may
be specified for such Debt Securities; (19) whether such Debt Securities are to

global securities and, if so, the identity of the depositary or its nominee, if
any, for such global security or securities and the circumstances under which
beneficial owners of interests in the global security may exchange such
interests for certificated Debt Securities to be registered in the names of or
to be held by such beneficial owners or their nominees; (20) in the case of the
Senior Subordinated Indentures, the relative degree to which such Debt
Securities of the series shall be senior to or be subordinated to other series
of such Debt Securities, and to other indebtedness of Allied, or AWNA or any
Guarantor, as the case may be, in right of payment, whether such other series of
Debt Securities and other indebtedness are outstanding or not; (21) whether such
Debt Securities are secured or unsecured and, if secured, the security and
related terms in connection therewith; (22) the terms, if any, upon which such
Debt Securities may be converted or exchanged into or for Common Stock,
Preferred Stock or other securities or property of Allied; (23) any restrictions
on the registration, transfer or exchange of the Debt Securities; and (24) any
other terms not inconsistent with the terms of the Indentures pertaining to such
Debt Securities. (Section 3.1 of each Indenture) Unless otherwise specified in
the applicable Prospectus Supplement, the Debt Securities will not be listed on
any securities exchange.
 
     The number of shares of Common Stock or Preferred Stock that will be
issuable upon the conversion or exchange of any Debt Securities issued with
conversion or exchange provisions will be adjusted to prevent dilution resulting
from stock splits, stock dividends or similar transactions, and the nature and
amount of the securities, assets or other property to be received upon the
conversion or exchange of such Debt Securities will be changed as necessary in
the event of any consolidation, merger, combination or similar transaction. The
specific provisions will be set forth in the applicable Prospectus Supplement.
 
     Unless otherwise specified in the applicable Prospectus Supplement, Debt
Securities in registered form will be issued in denominations of U.S.$1,000 or
any integral multiples of U.S.$1,000 and Debt Securities in bearer form will be
issued in denominations of U.S.$5,000 or any integral multiples of U.S.$5,000.
(Section 3.2 of each Indenture) Where Debt Securities of any series are issued
in bearer form, the special restrictions and considerations, including special
offering restrictions and material U.S. federal income tax considerations,
applicable to any such Debt Securities and to payments in respect of and
transfers and exchanges of such Debt Securities will be described in the
applicable Prospectus Supplement. Debt Securities in bearer form will be
transferable by delivery. (Section 3.5 of each Indenture)
 
     Debt Securities may be sold at a substantial discount below their stated
principal amount, bearing no interest or interest at a rate which at the time of
issuance is below market rates. Material U.S. federal income tax consequences
and special considerations applicable to any such Debt Securities will be
described in the applicable Prospectus Supplement.
 
     If the purchase price of any of the Debt Securities is payable in one or
more foreign currencies or currency units or if any Debt Securities are
denominated in one or more foreign currencies or currency units or if the
principal of, premium, if any, or interest, if any, on any Debt Securities is
payable in one or more foreign currencies or currency units, the restrictions,
elections, material U.S. federal income tax considerations and
 
                                        9
<PAGE>   11
 
other information with respect to such issue of Debt Securities and such foreign
currency or currency units will be set forth in the applicable Prospectus
Supplement.
 
     If any index is used to determine the amount of payments of principal of,
premium, if any, or interest, if any, on any series of Debt Securities, material
U.S. federal income tax, accounting and other considerations applicable thereto
will be described in the applicable Prospectus Supplement.
 
     The general provisions of the Indentures do not afford holders of the Debt
Securities protection in the event of a highly leveraged transaction,
restructuring, change in control, merger or similar transaction involving Allied
that may adversely affect holders of the Debt Securities.
 
PAYMENT, REGISTRATION, TRANSFER AND EXCHANGE
 
     Unless otherwise provided in the applicable Prospectus Supplement, payments
in respect of the Debt Securities will be made in the designated currency at
such office or agency of Allied or AWNA, as the case may be, maintained for that
purpose as Allied or AWNA, as the case may be, may designate from time to time,
except that, at the option of Allied or AWNA, as the case may be, interest
payments, if any, on Debt Securities in registered form may be made (i) by
checks mailed to the holders of Debt Securities entitled thereto at their
registered addresses or (ii) by wire transfer to an account maintained by the
holders of the Debt Securities entitled thereto as specified in the Register.
(Sections 3.7(a) and 9.2 of each Indenture) Each payment in respect of the Debt
Securities shall be considered to have been made on the date such payment is due
if there shall have been sent to the Trustee or paying agent by wire transfer
(received by no later than the business day following such due date), or the
Trustee or paying agent otherwise holds, on such due date sufficient funds to
make such payment. (Section 9.1 of each Indenture) Unless otherwise indicated in
an applicable Prospectus Supplement, scheduled payments of any installment of
interest on Debt Securities in registered form will be made to the person in
whose name such Debt Security is registered at the close of business on the
regular record date for such interest. (Section 3.7(a) of each Indenture)
 
     Payment in respect of Debt Securities in bearer form will be made in the
currency and in the manner designated in the Prospectus Supplement, subject to
any applicable laws and regulations, at such paying agencies outside the United
States as Allied or AWNA, as the case may be, may appoint from time to time. The
paying agents outside the United States, if any, initially appointed by Allied
or AWNA, as the case may be, for a series of Debt Securities will be named in
the Prospectus Supplement. Unless otherwise provided in the applicable
Prospectus Supplement, Allied or AWNA, as the case may be, may at any time
designate additional paying agents or rescind the designation of any paying
agents, except that, if Debt Securities of a series are issuable in registered
form, Allied or AWNA, as the case may be, will be required to maintain at least
one paying agent in each place of payment for such series and if Debt Securities
of a series are issuable in bearer form, Allied or AWNA, as the case may be,
will be required to maintain at least one paying agent in a place of payment
outside the United States where Debt Securities of such series and any coupons
appertaining thereto may be presented and surrendered for payment. (Section 9.2
of each Indenture)
 
     Unless otherwise provided in the applicable Prospectus Supplement, Debt
Securities in registered form will be transferable or exchangeable at the agency
of Allied or AWNA, as the case may be, maintained for such purpose as designated
by Allied or AWNA, as the case may be, from time to time. (Sections 3.5 and 9.2
of each Indenture) Debt Securities may be transferred or exchanged without
service charge, although Allied or AWNA, as the case may be, may require a
holder to pay any tax or other governmental charge imposed in connection
therewith. (Section 3.5 of each Indenture)
 
GLOBAL DEBT SECURITIES
 
     The Debt Securities of a series may be issued in whole or in part in the
form of one or more fully registered global securities (a "Registered Global
Security"). Each Registered Global Security will be registered in the name of a
depositary (the "Depositary") or a nominee for the Depositary identified in the
applicable Prospectus Supplement, will be deposited with such Depositary or
nominee or a custodian therefor and will bear a legend regarding the
restrictions on exchanges and registration of transfer thereof and any such
other matters as may be provided for pursuant to the applicable Indenture. In
such a case, one or more
 
                                       10
<PAGE>   12
 
Registered Global Securities will be issued in a denomination or aggregate
denominations equal to the portion of the aggregate principal amount of
outstanding Debt Securities of the series to be represented by such Registered
Global Security or Securities. (Section 3.3 of each Indenture) Unless and until
it is exchanged in whole or in part for Debt Securities in definitive
certificated form, a Registered Global Security may not be transferred or
exchanged except as a whole by the Depositary for such Registered Global
Security to a nominee of such Depositary or by a nominee of such Depositary to
such Depositary or another nominee of such Depositary or by such Depositary or
any such nominee to a successor Depositary for such series or a nominee of such
successor Depositary, or except in the circumstances described in the applicable
Prospectus Supplement. (Section 3.5 of each Indenture)
 
     The specific terms of the depositary arrangement with respect to any
portion of a series of Debt Securities to be represented by a Registered Global
Security will be described in the applicable Prospectus Supplement.
 
     Upon the issuance of any Registered Global Security, and the deposit of
such Registered Global Security with or on behalf of the Depositary for such
Registered Global Security, the Depositary will credit on its book-entry
registration and transfer system the respective principal amounts of the Debt
Securities represented by such Registered Global Security to the accounts of
institutions ("Participants") that have accounts with the Depositary. The
accounts to be credited will be designated by the underwriters or agents
engaging in the distribution of such Debt Securities or by Allied or AWNA, as
the case may be, if such Debt Securities are offered and sold directly by Allied
or AWNA, as the case may be. Ownership of beneficial interests in a Registered
Global Security will be limited to Participants or persons that may hold
interests through Participants. Ownership of beneficial interests in a
Registered Global Security will be shown on, and the transfer of that ownership
will be effected only through, records maintained by the Depositary for such
Registered Global Security or by its nominee. Ownership of beneficial interests
in such Registered Global Security by persons who hold through Participants will
be shown on, and the transfer of such beneficial interests within such
Participants will be effected only through, records maintained by such
Participants.
 
     So long as the Depositary for a Registered Global Security, or its nominee,
is the owner of such Registered Global Security, such Depositary or such
nominee, as the case may be, will be considered the sole owner or holder of the
Debt Security represented by such Registered Global Security for all purposes
under each Indenture. (Section 3.8 of each Indenture) Accordingly, each person
owning a beneficial interest in such Registered Global Security must rely on the
procedures of the Depositary and, 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 such Indenture. Each of Allied and AWNA
understands that under existing industry practices, if it requests any action of
holders or if an owner of a beneficial interest in a Registered Global Security
desires to give or take any instruction or action which a holder is entitled to
give or take under the Indenture, the Depositary would authorize the
Participants holding the relevant beneficial interests to give or take such
instruction or action, and such Participants would authorize beneficial owners
owning through such Participants to give or take such instruction or action or
would otherwise act upon the instructions of beneficial owners holding through
them.
 
     Unless otherwise specified in the Prospectus Supplement, payments with
respect to principal, premium, if any, and interest, if any, on the Debt
Securities represented by a Registered Global Security registered in the name of
the Depositary or its nominee will be made to such Depositary or its nominee, as
the case may be, as the registered owner of such Registered Global Security.
Each of Allied and AWNA expects that the Depositary for any Debt Securities
represented by a Registered Global Security, upon receipt of any payment of
principal or interest in respect of such Registered Global Security, will credit
immediately Participants' accounts with payments in amounts proportionate to
their respective beneficial interests in the Registered Global Security as shown
on the records of the Depositary. Each of Allied and AWNA also expects that
payments by Participants to owners of beneficial interests in such Registered
Global Security held through such Participants will be governed by standing
instructions and customary practices, as is now the case with securities in
bearer form held for the accounts of customers or registered in "street name,"
and will be the responsibility of such Participants. None of Allied, AWNA, any
Guarantor, the respective Trustees or any agent of Allied, AWNA, any Guarantor
or the respective Trustees shall have any responsibility or liability for any
aspect of the records relating to or payments made on account of beneficial
interests in any Registered
 
                                       11
<PAGE>   13
 
Global Security, or for maintaining, supervising or reviewing any records
relating to such beneficial interests. (Section 3.8 of each Indenture)
 
     Unless otherwise specified in the applicable Prospectus Supplement, if the
Depositary for any Debt Securities represented by a Registered Global Security
is at any time unwilling or unable to continue as depositary of such Registered
Global Security and a successor depositary is not appointed by Allied or AWNA,
as the case may be, within 90 days, Allied or AWNA, as the case may be, will
issue Debt Securities in certificated form in exchange for such Registered
Global Security. In addition, Allied or AWNA, as the case may be, in its sole
discretion may at any time determine not to have any of the Debt Securities of a
series represented by one or more Registered Global Securities and, in such
event, will issue Debt Securities of such series in certificated form in
exchange for all of the Registered Global Securities representing such series of
Debt Securities. (Section 3.5 of each Indenture)
 
     The Debt Securities of a series may also be issued in whole or in part in
the form of one or more bearer global securities (a "Bearer Global Security")
that will be deposited with a depositary, or with a nominee for such depositary,
identified in the applicable Prospectus Supplement. Any such Bearer Global
Securities may be issued in temporary or permanent form. (Section 3.4 of each
Indenture) The specific terms and procedures, including the specific terms of
the depositary arrangement, with respect to any portion of a series of Debt
Securities to be represented by one or more Bearer Global Securities will be
described in the applicable Prospectus Supplement.
 
CONSOLIDATION, MERGER OR SALE OF ASSETS
 
     Each Indenture permits Allied, or AWNA or any Guarantor, as the case may
be, to consolidate with or merge into any person or persons or to sell, transfer
or lease its properties and assets as, or substantially as, an entirety to any
person if, (i) the person (if other than Allied, or AWNA or such Guarantor, as
the case may be,) formed by such consolidation, or into which Allied, or AWNA or
such Guarantor, as the case may be, is merged or which acquires or leases the
properties and assets of Allied, or AWNA or such Guarantor, as the case may be,
as, or substantially as, an entirety, is organized and existing under the laws
of the United States, any state thereof or the District of Columbia, (ii) such
person expressly assumes Allied's, or AWNA's or such Guarantor's, as the case
may be, obligations on the Debt Securities issued under such Indenture, (iii)
immediately after giving effect to such consolidation, merger, sale, transfer or
lease, no Default or Event of Default under such Indenture exists and (iv) with
respect to any series of Debt Securities, Allied, or AWNA or such Guarantor, as
the case may be, satisfies any other conditions, if any, established with
respect to such series of Debt Securities pursuant to and in accordance with
Section 3.1 of the applicable Indenture. (Section 7.1 of each Indenture)
 
EVENTS OF DEFAULT, NOTICE AND CERTAIN RIGHTS ON DEFAULT
 
     Except as otherwise provided in a Prospectus Supplement relating to the
Debt Securities of a particular series, Events of Default with respect to Debt
Securities of any series are defined in each Indenture as (a) default in the
payment of any interest on any Debt Security of that series, and the continuance
of such default for a period of 30 days; (b) default in the payment of any
installment of the principal of or any premium on any Debt Security of that
series when due, whether at maturity, upon redemption, by declaration or
otherwise or in the payment of a mandatory sinking fund payment when and as due
by the forms of the Debt Securities of that series; (c) failure by Allied, or
AWNA or any Guarantor, as the case may be, to comply with any other covenant or
agreement contained in the Indenture under which the Debt Securities of that
series were issued and the continuance of such default for a period of 90 days
after written notice as provided in such Indenture; (d) certain events of
bankruptcy, insolvency and reorganization of Allied, or AWNA or any Guarantor,
as the case may be; and (e) default by Allied, or AWNA or any Guarantor, as the
case may be, under any indenture or other instrument under which any
indebtedness for borrowed money having an outstanding aggregate principal amount
of at least $25 million has been issued or by which it is governed as a result
of which such indebtedness shall have been accelerated, and such acceleration is
not rescinded, cured or annulled within 30 days after written notice thereof to
Allied, or AWNA or any Guarantor, as the case may be, by the Trustee for such
series or to Allied, or AWNA or any Guarantor, as the case may
 
                                       12
<PAGE>   14
 
be, and the Trustee for such series by the holders of at least 25% of the
aggregate principal amount of the Debt Securities of such series then
outstanding, provided that such Event of Default will be cured or waived if the
default that resulted in the acceleration of such other indebtedness is cured or
waived, as the case may be. (Section 5.1 of each Indenture) Events of Default
with respect to a specified series of Debt Securities may be deleted from or
added to the Indenture or may be modified and, if so deleted, added or modified,
will be described in the applicable Prospectus Supplement. (Sections 3.1 and 5.1
of each Indenture)
 
     Each Indenture provides that the relevant Trustee will, within 90 days
after the occurrence of a Default that is continuing with respect to the Debt
Securities of any series, give to the holders of the Debt Securities of that
series notice of all Defaults known to it unless such Default shall have been
cured or waived; provided that except in the case of a Default in payment of
principal, premium, if any, or interest on the Debt Securities of that series,
such Trustee shall be protected in withholding such notice if it in good faith
determines that withholding such notice is in the interests of holders of the
Debt Securities of that series. (Section 6.6 of each Indenture) "Default" means
any event which is, or after notice or passage of time, or both, would be, an
Event of Default. (Section 1.1 of each Indenture)
 
     Each Indenture provides that, if an Event of Default specified therein
(other than an Event of Default of the type described in clause (d) of the
second preceding paragraph) occurs with respect to the Debt Securities of any
series and is continuing, the Trustee for such series or the holders of 25% in
aggregate principal amount of all outstanding Debt Securities of that series
(calculated as provided for in each Indenture) may declare the principal of (or,
if the Debt Securities of that series are Original Issue Discount Securities or
Indexed Securities, such portion of the principal amount specified in the
Prospectus Supplement) and accrued interest, if any, on all the Debt Securities
of that series to be due and payable and upon such declaration, such principal
(or, in the case of Original Issue Discount Securities or Indexed Securities,
such portion of the principal amount specified in the Prospectus Supplement) and
interest, if any, shall be immediately due and payable. If an Event of Default
of the type described in clause (d) of the second preceding paragraph occurs
with respect to the Debt Securities of any series and is continuing, then the
principal of (or, if the Debt Securities of that series are Original Issue
Discount Securities or Indexed Securities, the applicable portion of such
principal amount) and accrued interest, if any, on all the Debt Securities of
that series shall be immediately due and payable without any declaration or act
on the part of the Trustee for such series or any holder of such Debt
Securities. If the principal of and interest on Senior Subordinated Securities
is accelerated as described in this paragraph, the payment of such principal and
interest shall remain subordinated to the extent provided in Article 15 of the
Senior Subordinated Indenture. (Section 5.2 of each Indenture)
 
     Each Indenture provides that the holders of not less than a majority in
aggregate principal amount of any series of Debt Securities by written notice to
the Trustee for such series may waive, on behalf of the holders of all Debt
Securities of such series, any past Default or Event of Default with respect to
that series and its consequences except a Default or Event of Default in the
payment of the principal of, premium, if any, or interest, if any, on any Debt
Security or with respect to a covenant or provision that cannot be amended or
modified without consent of each holder of such series of Debt Securities
adversely affected. (Section 5.7 of each Indenture)
 
     Reference is made to the Prospectus Supplement relating to each series of
Debt Securities that are Original Issue Discount Securities for the particular
provisions relating to acceleration of the maturity of a portion of the
principal amount of such Original Issue Discount Securities upon the occurrence
of an Event of Default and the continuation thereof.
 
     Each Indenture provides that, if a Default or an Event of Default shall
have occurred and be continuing, the holders of not less than a majority in
aggregate principal amount of the Debt Securities of each series affected (with
each such series voting as a class) may, subject to certain limited conditions,
direct the time, method and place of conducting any proceeding for any remedy
available to the Trustee for such series, or exercising any trust or power
conferred on such Trustee. (Section 5.8 of each Indenture)
 
     Each Indenture includes a covenant that Allied, or AWNA, as the case may
be, will file annually with the relevant Trustee a certificate as to the
presence or absence of certain defaults under the terms of such Indenture.
(Section 9.7 of each Indenture)

MODIFICATION AND WAIVER
 
     Each Indenture contains provisions permitting Allied, or AWNA and the
Guarantors, as the case may be, and the relevant Trustee to enter into one or
more supplemental indentures without the consent of the holders of any of the
Debt Securities in order (i) to evidence the succession of another entity to
Allied, or AWNA or any Guarantor, as the case may be, and the assumption of the
covenants and obligations of Allied, or AWNA or any Guarantor, as the case may
be, under the Debt Securities and such Indenture by such successor to Allied, or
AWNA or any Guarantor, as the case may be; (ii) to add to the covenants of
Allied, or AWNA or any Guarantor, as the case may be, for the benefit of the
holders of all or any series of Debt Securities or surrender any right or power
conferred on Allied, or AWNA or any Guarantor, as the case may be, by such
Indenture; (iii) to add additional Events of Default with respect to any series
of Debt Securities; (iv) to add to or change any provisions to such extent as

Securities not yet issued; (vi) to secure the Debt Securities; (vii) to
establish the form or terms of Debt Securities of any series; (viii) to evidence
and provide for successor Trustees or to add or change any provisions to such
extent as necessary to permit or facilitate the appointment of a separate
Trustee or Trustees for specific series of Debt Securities; (ix) to permit
payment in respect of Debt Securities in bearer form in the United States to the
extent allowed by law; (x) to correct or supplement any inconsistent provisions
or to make any other provisions with respect to matters or questions arising
under such Indenture, provided that any such action does not adversely affect in
any material respect the interests of any holder of Debt Securities of any
series then outstanding; (xi) to cure any ambiguity, correct any mistake or
comply with any mandatory provision of law; (xii) in the case of the Senior
Subordinated Indentures, to modify the subordination provisions thereof in a
manner not adverse to the holders of Senior Subordinated Securities of any
series then outstanding; (xiii) to make provision with respect to any conversion
or exchange rights of holders not adverse to the holders of any Debt Securities
of any series then outstanding with such conversion or exchange rights,
including providing for the conversion or exchange of Debt Securities into
Common Stock or Preferred Stock or other securities or property of Allied; or
(xiv) to effect the qualification of such Indenture under the TIA or to add
provisions expressly required under the TIA. (Section 8.1 of each Indenture)
 
     Each Indenture also contains provisions permitting Allied, or AWNA and the
Guarantors, as the case may be, and the relevant Trustee, with the consent of
the holders of a majority in aggregate principal amount of the outstanding Debt
Securities of all series adversely affected by such supplemental indenture
(voting as one class), to execute supplemental indentures adding any provisions
to or changing or eliminating any of the provisions of such Indenture or any
supplemental indenture or modifying the rights of the holders of Debt Securities
of such series, except that, without the consent of the holder of each Debt
Security so affected, no such supplemental indenture may: (i) change the time
for payment of principal or premium, if any, or interest on any Debt Security;
(ii) reduce the principal on any Debt Security, or change the manner in which
the amount of any of the foregoing is determined; (iii) reduce the interest
rate, or reduce the amount of premium, if any, payable upon the redemption of
any Debt Security or change the manner in which the amount of the premium, if
any, or interest is determined; (iv) reduce the amount of principal payable upon
acceleration of the maturity of any Original Issue Discount or Indexed Security;

compliance with certain provisions of the Indenture or for waiver of certain
defaults, or reduce the quorum or voting requirements applicable to meetings of
holders of Debt Securities issuable in bearer form; (viii) change the obligation
of Allied to maintain an office or agency in the places and for the purposes
specified in such Indenture; (ix) in the case of the Senior Subordinated
Indenture, modify the subordination provisions thereof in a manner adverse to
the holders of Senior Subordinated Securities of any series then outstanding;
(x) modify the provisions that set forth the provisions in each Indenture that

                                       14
<PAGE>   16
 
rights of the holders to convert or exchange convertible or exchangeable Debt
Securities. (Section 8.2 of each Indenture)
 
     The Holders of a majority in aggregate principal amount of the Outstanding
Debt Securities of any series may waive compliance by Allied, or AWNA or any
Guarantor, as the case may be, with certain restrictive provisions of the
applicable Indenture (Section 9.6 of each Indenture). The Holders of a majority
in aggregate principal amount of the Outstanding Debt Securities of any series
may waive any past default under the applicable Indenture, except a default in
the payment of principal, premium or interest and certain covenants and
provisions of the applicable Indenture which cannot be amended without the
consent of the Holder of each Outstanding Debt Security of such series affected.
(Section 5.7 of each Indenture)
 
SUBORDINATION UNDER THE SENIOR SUBORDINATED INDENTURES
 
     The payment of the principal of (and premium, if any) and interest on the
Senior Subordinated Debt Securities will, in certain circumstances as set forth
in the applicable Senior Subordinated Indenture, be subordinated in right of
payment to the prior payment in full of all Senior Debt of Allied or AWNA, as
the case may be. Upon any payment or distribution of assets of Allied or AWNA,
as the case may be, to creditors upon any liquidation, dissolution, winding up,
reorganization, assignment for the benefit of creditors, marshalling of assets
and liabilities or any bankruptcy, insolvency or similar proceedings of Allied
or AWNA, as the case may be, the holders of Senior Debt of Allied or AWNA, as
the case may be, will be entitled to receive payment in full of the principal of
(and premium, if any) and interest on such Senior Debt, including all amounts
due or to become due on all such Senior Debt, or provision will be made for
payment in cash or cash equivalents or otherwise in a manner satisfactory to the
holders of such Senior Debt, before the holders of Senior Subordinated Debt
Securities of Allied or AWNA, as the case may be, are entitled to receive any
Securities Payments. "Securities Payment" means any payment or distribution of
any kind, whether in cash, property or securities (including any payment or
distribution deliverable by reason of the payment of any other Debt subordinated
to the Senior Subordinated Debt Securities) on account of the principal of (and
premium, if any) or interest on the Senior Subordinated Debt Securities or on
account of the purchase or redemption or other acquisition of Senior
Subordinated Debt Securities by Allied, AWNA or any subsidiary of Allied. In the
event that, notwithstanding the foregoing, the applicable Senior Subordinated
Trustee or the holder of any Senior Subordinated Debt Securities receives any
Securities Payment before all Senior Debt of Allied, or AWNA, as the case may
be, is paid in full or payment thereof is provided for in cash or cash
equivalents or otherwise in a manner satisfactory to the holders of such Senior
Debt, then and in such event such Debt Securities Payment will be required to be
paid over or delivered forthwith to the holders of Senior Debt for application
to the payment of all Senior Debt of Allied or AWNA, as the case may be,
remaining unpaid, to the extent necessary to pay such Senior Debt in full.
(Sections 15.1 and 15.2 of the Senior Subordinated Allied Indenture and the
Senior Subordinated AWNA Indenture)
 
     Allied or AWNA, as the case may be, may not make any Securities Payments if
there has occurred and is continuing a default in the payment of the principal
of (or premium, if any) or interest on Senior Debt of Allied or AWNA, as the
case may be, or if there has occurred and is continuing any event of default
with respect to Senior Debt of Allied or AWNA, as the case may be, which has
resulted in such Senior Debt becoming or being declared due and payable prior to
the date on which it would otherwise have become due and payable (a "Senior
Payment Default"). In addition, if any default (other than a Senior Payment
Default), with respect to any Senior Debt of Allied or AWNA, as the case may be,
permitting after notice or lapse of time (or both) the holders thereof (or a
trustee on behalf thereof) to accelerate the maturity thereof (a "Senior
Nonmonetary Default") has occurred and is continuing and Allied or AWNA, as the
case may be, and the applicable Senior Subordinated Trustee have received
written notice thereof from the Agent Bank under the Credit Agreement (or if
such Credit Agreement has been terminated, from any holder or holders of Senior
Debt of Allied or AWNA, as the case may be, with a principal amount in excess of
$50 million), then Allied may not make any Securities Payments for a period (a
"blockage period") commencing on the date Allied or AWNA, as the case may be,
and the applicable Senior Subordinated Trustee receive such written notice and
ending on the earlier of (x) 179 days after such date and (y) the date if any,
on which the Senior Debt of Allied or AWNA, as the case may be, to which such
default relates is discharged or such default is
 
                                       15
<PAGE>   17
 
waived or otherwise cured. (Section 15.3 of the Senior Subordinated Allied
Indenture the Senior Subordinated AWNA Indenture)
 
     In any event, not more than one blockage period with respect to any Senior
Subordinated Debt Securities may be commenced during any period of 360
consecutive days. No Senior Payment Default or Senior Nonmonetary Default that
existed or was continuing on the date of commencement of any blockage period
with respect to the Senior Debt of Allied or AWNA, as the case may be, will be,
or can be, made the basis for the commencement of a subsequent blockage period,
unless such default has been cured for a period of not less than 90 consecutive
days. In the event that, notwithstanding the foregoing, Allied or AWNA, as the
case may be, makes any Securities Payment to the applicable Senior Subordinated
Trustee or any holder of the applicable Senior Subordinated Debt Securities
prohibited by the subordination provisions, then and in such event such Debt
Securities Payment will be required to be paid over and delivered forthwith to
the holders of the Senior Debt of Allied or AWNA, as the case may be. (Section
15.3 of the Senior Subordinated Allied Indenture and the Senior Subordinated
AWNA Indenture)
 
     By reason of such subordination, in the event of insolvency, creditors of
Allied or AWNA, as the case may be, who are not holders of Senior Debt of Allied
or AWNA, as the case may be, or of the applicable Senior Subordinated Debt
Securities may recover less, ratably, than holders of such Senior Debt and may
recover more, ratably, than the holders of the applicable Senior Subordinated
Debt Securities.
 
     "Senior Debt" means, except as otherwise provided in a Prospectus
Supplement relating to any series of Debt Securities, (i) with respect to AWNA,
Debt created pursuant to the Amended and Restated Credit Agreement dated June 5,
1997 among Allied, AWNA, Credit Suisse First Boston, Citibank, N.A., Goldman
Sachs Credit Partners L.P. and the other bank lenders named therein (the "Credit
Agreement"), (ii) with respect to Allied or AWNA, as the case may be, any
Restricted Subsidiary of Allied or AWNA, as the case may be, or, in the case of
the Senior Subordinated AWNA Indenture, any Guarantor, (a) every obligation of
such Person for money borrowed, (b) every obligation of such Person evidenced by
bonds, debentures, notes or other similar instruments, including obligations
incurred in connection with the acquisition of property, assets or businesses,
(c) every reimbursement obligation of such Person with respect to letters of
credit, bankers' acceptances or similar facilities issued for the account of
such Person, (d) every Capital Lease Obligation of such Person and (e) every
payment obligation of such Person under interest rate swap or similar agreements
or foreign currency hedge, exchange or similar agreements at the time of
determination, whether incurred on or prior to the date of the applicable
Indenture or thereafter incurred, (iii) with respect to Allied or AWNA, as the
case may be, any Restricted Subsidiary of Allied or AWNA, as the case may be,
or, in the case of the Senior Subordinated AWNA Indenture, any Guarantor,
guarantees by such person of Senior Debt and (iv) amendments, modifications,
renewals, extensions, refinancings and refundings of any such Debt; provided,
however, the following shall not constitute Senior Debt: (A) any Debt owed to a
Person when such Person is a Subsidiary of Allied or AWNA, as the case may be,
(B) any Debt which by the terms of the instrument creating or evidencing the
same is pari passu or subordinate in right of payment to the applicable Senior
Subordinated Debt Securities, (C) any Debt incurred in violation of the
applicable Indenture or (D) any Debt which is subordinate in right of payment in
any respect to any other Debt of Allied or AWNA, as the case may be. For
purposes of this definition, "Debt" includes any obligation to pay principal,
premium (if any), interest, penalties, reimbursement or indemnity amounts, fees
and expenses (including interest accruing on or after the filing of any petition
in bankruptcy or for reorganization relating to Allied or AWNA, as the case may
be, whether or not a claim for post-petition interest is allowed in such
proceeding).
 
     "Restricted Subsidiary" means, with respect to any series of Debt
Securities, any Subsidiary of Allied or AWNA, as the case may be, which is not
designated by the Company as an Unrestricted Subsidiary (as defined in any
Prospectus Supplement relating to any series of Debt Securities) with respect to
such series of Debt Securities upon the issuance of such series of Debt
Securities.
 
     The subordination provisions described above will cease to be applicable to
the applicable Senior Subordinated Debt Securities upon any defeasance or
covenant defeasance of such Senior Subordinated Debt Securities as described
under "-- Defeasance and Covenant Defeasance."

     The Senior Subordinated Indenture places no limitation on the amount of
additional Senior Debt that may be incurred by Allied. Allied expects from time
to time to incur additional indebtedness constituting Senior Debt.
 
     The Senior Subordinated Indenture provides that the foregoing subordination
provisions, insofar as they relate to any particular issue of Senior
Subordinated Securities, may be changed prior to such issuance. Any such change
would be described in the Prospectus Supplement relating to such Senior
Subordinated Securities. (Section 3.1 of the Senior Subordinated Indenture)
 
GUARANTEES
 
     The Guarantors will, jointly and severally, on a senior basis,
unconditionally guarantee (the "Senior Guarantees") the due and punctual payment
of principal of (and premium, if any) and interest on the Senior AWNA Debt
Securities. The Guarantors will, jointly and severally, on a senior subordinated
basis, unconditionally guarantee (the "Senior Subordinated Guarantees" and,
together with the Senior Guarantees (the "Guarantees")) the due and punctual
payment of principal of (and premium, if any) and interest on the Senior
Subordinated AWNA Debt Securities, when and as the same shall become due and
payable, whether at the maturity date, by declaration of acceleration, call for
redemption or otherwise.
 
     The Senior Guarantees, when issued, will rank pari passu in right of
payment with all other unsubordinated obligations of the Guarantors, and will
rank senior in right of payment to all subordinated obligations of the
Guarantors. The Senior Subordinated Guarantees, when issued, will be subordinate
in right of payment to the prior payment in full of all Senior Debt of the
Guarantors, including, in the case of Allied, all Senior Allied Debt Securities,
and will rank pari passu in right of payment with all other senior subordinated
obligations of the Guarantors. No payment will be made by any Guarantor under
its Senior Subordinated Guarantee in respect of the Senior Subordinated AWNA
Debt Securities during any period that payments by AWNA on the Senior
Subordinated AWNA Debt Securities are suspended by the subordination provisions
of the Senior Subordinated AWNA Indenture. (Sections 16.1, 16.2 and 16.3 of the
Senior Subordinated Indentures)
 
     The AWNA Debt Securities Guarantees will remain in effect with respect to
each Guarantor until the entire principal of premium, if any, and interest on
the applicable AWNA Debt Securities shall have been paid in full or otherwise
discharged in accordance with the provisions of the applicable Indenture;
provided, however, that (i) with respect to each Guarantor, if the applicable
AWNA Debt Securities are defeased and discharged as described under
"-- Defeasance and Discharge," or (ii) with respect to each Subsidiary
Guarantor, such Subsidiary Guarantor (x) ceases to be a Restricted Subsidiary or
(y) all or substantially all of the assets of such Subsidiary Guarantor or all
of the capital stock of such Subsidiary Guarantor is sold (including by
issuance, merger, consolidation or otherwise) by the Company or any of its
Subsidiaries in a transaction in accordance with the Indenture, then in each
case of (i) and (ii) above, such Guarantor or the corporation acquiring such
assets (in the event of a sale or other disposition of all or substantially all
of the assets of such Subsidiary Guarantor) shall be released and discharged
from the applicable Guarantee obligations.
 
     Subject to payment in full of all Senior Debt of any Guarantor, the rights
of the holders of the Senior Subordinated AWNA Debt Securities under the related
Senior Subordinated Guarantees of such Guarantor will be subrogated to the
rights of the holders of such Senior Debt to receive payments or distributions
of cash, property or securities of the Guarantor applicable to Senior Debt of
such Guarantor.
 
     Because Allied is a holding company, the rights of its creditors, including
the Holders of the AWNA Debt Securities in the event the Guarantees are
enforced, to share in the distribution of the assets of any subsidiary upon the
subsidiary's liquidation or recapitalization will be subject to the prior claims
of the subsidiary's creditors, except to the extent Allied may itself be a
creditor with recognized claims against the subsidiary. See "-- General" above.

DEFEASANCE AND COVENANT DEFEASANCE
 
     Defeasance and Discharge.  Unless otherwise provided in the applicable
Prospectus Supplement relating to the Debt Securities of a particular series,
Allied or AWNA, as the case may be, will be discharged from any and all
obligations in respect of the Debt Securities of, or within, any series (except
for certain obligations to register the transfer or exchange of Debt Securities,
to replace stolen, lost or mutilated Debt Securities, to convert or exchange
Debt Securities, to maintain paying agencies and to hold monies for payment in
trust) upon the deposit with the relevant Trustee, in trust, of money and/or
Government Obligations which through the payment of interest and principal in
respect thereof in accordance with their terms will provide money in an amount
sufficient to pay the principal of, premium, if any, and each installment of
interest on such Debt Securities at the maturity of such payments in accordance
with the terms of the applicable Indenture and such Debt Securities. (Sections
3.1 and 4.4 of each Indenture) Such a trust may only be established if, among
other things, Allied or AWNA, as the case may be, delivers to the relevant
Trustee an officer's certificate and opinion of counsel (who may be counsel to
Allied or AWNA, as the case may be) stating that (A) either (i) Allied or AWNA,
as the case may be, has received from, or there has been published by, the
Internal Revenue Service a ruling or (ii) since the date of the Indenture there
has been a change in the applicable Federal income tax law, to the effect that
holders of such Debt Securities will not recognize income, gain or loss for
Federal income tax purposes as a result of such defeasance and will be subject
to Federal income tax on the same amount and in the same manner and at the same
times as would have been the case if such defeasance had not occurred and (B)
all conditions precedent in the applicable Indenture relating to such defeasance
have been complied with. (Section 4.6 of the Indenture)
 
     Defeasance of Certain Covenants and Certain Events of Default.  Unless
otherwise provided in the applicable Prospectus Supplement relating to the Debt
Securities of a particular series, upon the deposit with the relevant Trustee,
in trust, of money and/or Government Obligations which through the payment of
interest and principal in respect thereof in accordance with their terms will
provide money in an amount sufficient to pay the principal of, premium, if any,
and each installment of interest on such Debt Securities at the maturity of such
payments in accordance with the terms of such Indenture and such Debt
Securities, Allied, or AWNA and the Guarantors, as the case may be, may omit to
comply with certain covenants applicable to the Debt Securities of, or within,
any series and the occurrence of any Event of Default described in clause (c) or
clause (e) under the caption "Events of Default, Notice and Certain Rights on
Default" above or any additional Event of Default established with respect to
such series of Debt Securities pursuant to Section 3.1 of the applicable
Indenture, shall not be deemed to be a Default or Event of Default under such
Indenture and such Debt Securities. The obligations of Allied, or AWNA and the
Guarantors, as the case may be, under such Indenture and such Debt Securities,
other than with respect to the covenants referred to above, and the Events of
Default, other than the Events of Default referred to above, shall remain in
full force and effect. (Sections 3.1 and 4.5 of each Indenture) Such a trust may
only be established if, among other things, Allied or AWNA, as the case may be,
has delivered to the relevant Trustee an officer's certificate and opinion of
counsel (who may be counsel to Allied or AWNA, as the case may be) to the effect
that (A) holders of such Debt Securities will not recognize income, gain or loss
for Federal income tax purposes as a result of such defeasance and will be
subject to income tax on the same amount and in the same manner and at the same
times as would have been the case if such defeasance had not occurred and (B)
all conditions precedent in the applicable Indenture relating to such covenant
defeasance have been complied with. (Section 4.6 of the Indenture)
 
     In addition, with respect to the Senior Subordinated Indenture, in order to
be discharged or omit compliance with certain covenants as described above, no
default in the payment of principal of, premium, if any, or interest on any
Senior Debt shall have occurred and be continuing and no other event of default
with respect to the Senior Debt shall have occurred and be continuing and shall
have resulted in such Senior Debt becoming or being declared due and payable
prior to the date it would have become due and payable. (Section 4.6 of the
Senior Subordinated Indenture)
 
     In the event Allied, or AWNA and the Guarantors, as the case may be,
exercise its or their option to omit compliance with certain covenants of the
Indenture with respect to such Debt Securities as described in the preceding
paragraphs and such Debt Securities are declared due and payable because of the
occurrence
 
                                       18
<PAGE>   20
 
of any Event of Default other than an Event of Default described in clause (c)
or (e) under the caption "Events of Default, Notice and Certain Rights on
Default" above, the amount of money and Government Obligations on deposit with
the relevant Trustee will be sufficient to pay amounts due on such Debt
Securities at the time of their stated maturity but may not be sufficient to pay
amounts due on such Debt Securities at the time of the acceleration resulting
from such Event of Default. However, Allied, or AWNA and the Guarantors, as the
case may be, would remain liable for any such deficiency.
 
NOTICES
 
     Notices to holders of registered Debt Securities will be given by mail to
the addresses of such holders as they may appear in the Register. (Section 1.6
of each Indenture)
 
OWNER OF DEBT SECURITIES
 
     Unless otherwise provided in the applicable Prospectus Supplement relating
to the Debt Securities of a particular series, Allied, or AWNA and the
Guarantors, as the case may be, the applicable Trustee and any agent of Allied,
or AWNA and the Guarantors, as the case may be, or the applicable Trustee, may
treat the person in whose name a Debt Security in registered form is registered,
and may treat the bearer of a Debt Security in bearer form, as the absolute
owner thereof (whether or not such Debt Security may be overdue) for the purpose
of receiving payment and for all other purposes. (Section 3.8 of each Indenture)
 
GOVERNING LAW
 
     The Indentures and the Debt Securities will be governed by, and construed
in accordance with, the laws of the State of New York. (Section 1.12 of each
Indenture)
 
THE TRUSTEE
 
     First Bank National Association, a national banking association, is the
Trustee under each of the Indentures. First Bank National Association is also
the Trustee under the Indenture dated as of May 15, 1997 (the "11.30%
Indenture") relating to Allied's 11.30% Senior Discount Notes due 2007 and the
Indenture dated as of December 1, 1996 (the "10 1/4% Indenture") relating to
AWNA's 10 1/4% Senior Subordinated Notes due 2006. Pursuant to the provisions of
the TIA, upon a default under any of the Senior Indentures, the Subordinated
Indentures, the 11.30% Indenture or the 10 1/4% Indenture, First Bank National
Association may be deemed to have a conflicting interest, by virtue of its
acting as the Trustee under each of the Indentures, thereby requiring it to
resign and be replaced by a successor Trustee under one or more of the
Indentures, the 11.30% Indenture or the 10 1/4% Indenture.
 
                            DESCRIPTION OF WARRANTS
 
     Allied may issue Warrants, including Warrants to purchase Allied Debt
Securities ("Debt Warrants"), Preferred Stock, Common Stock or other of its

Allied. The Warrants are to be issued under warrant agreements (each a "Warrant
Agreement") to be entered into between Allied and a bank or trust company, as
warrant agent (the "Warrant Agent"), all as shall be set forth in the Prospectus
Supplement relating to Warrants being offered pursuant thereto. The description
of the terms of the Warrants that are set forth below and that will be set forth
in the applicable Prospectus Supplement do not purport to be complete and are
qualified in their entirety by reference to the Warrant Agreement and warrant
certificate relating to such Warrants.

number of such Debt Warrants; (iv) the principal amount of Debt Securities
purchasable upon exercise of each Debt Warrant, and the price or prices at which
such Debt Warrants will be issued; (v) the procedures and conditions relating to

be exercised at any time; (x) if applicable, a discussion of material United
States Federal income tax considerations; (xi) any other terms of such Debt
Warrants and terms, procedures and limitations relating to the exercise of such
Debt Warrants; and (xii) the terms of the securities of Allied purchasable upon
exercise of such Debt Warrants. Prior to the exercise of their Debt Warrants,
holders of Debt Warrants exercisable for Debt Securities will not have any of
the rights of holders of the Debt Securities purchasable upon such exercise and
will not be entitled to payments of principal (or premium, if any) or interest,
if any, on the Debt Securities purchasable upon such exercise.
 
OTHER WARRANTS
 
     Allied may issue other Warrants. The applicable Prospectus Supplement will
describe the following terms of any such other Warrants in respect of which this
Prospectus is being delivered: (i) the title of such Warrants; (ii) the
securities (which may include Preferred Stock or Common Stock) for which such
Warrants are exercisable; (iii) the price or prices at which such Warrants will
be issued; (iv) if applicable, the designation and terms of the Preferred Stock

applicable Prospectus Supplement will also set forth (a) the amount of
securities called for by such Warrants, and, if applicable, the amount of
Warrants outstanding, and (b) information relating to provisions, if any, for a
change in the exercise price or the expiration date of such Warrants and the
kind, frequency and timing of any notice to be given. Prior to the exercise of
their Warrants for shares of Preferred Stock or Common Stock, holders of such
Warrants will not have any rights of holders of the Preferred Stock or Common
Stock purchasable upon such exercise and will not be entitled to dividend
payments, if any, or voting rights of the Preferred Stock or Common Stock
purchasable upon such exercise.
 
EXERCISE OF WARRANTS
 
     Each Warrant will entitle the holder thereof to purchase for cash or other
consideration such principal amount or such number of securities of Allied or
AWNA, as the case may be, at such exercise price as shall in each case be set
forth in, or be determinable as set forth in, the Prospectus Supplement relating
to the Warrants offered thereby. Warrants may be exercised as set forth in the
Prospectus Supplement relating to the Warrants offered thereby at any time up to
the close of business on the expiration date set forth in such Prospectus
Supplement. After the close of business on the expiration date (or such later
expiration date as may be extended by Allied), unexercised Warrants will become
void.
 
     Upon receipt of payment and the warrant certificate properly completed and
duly executed at the corporate trust office of the Warrant Agent or any other
office indicated in the applicable Prospectus Supplement, Allied will, as soon
as practicable, forward the securities purchasable upon such exercise. If less
than all of the Warrants represented by such warrant certificate are exercised,
a new warrant certificate will be issued for the remaining Warrants.

<PAGE>   22
 
MODIFICATIONS
 
     Each Warrant Agreement and the terms of the Warrants and the Warrant
Certificates issued thereunder may be amended by Allied and the applicable
Warrant Agent, without the consent of the holders, for the purpose of curing any
ambiguity, or of curing, correcting or supplementing any defective or
inconsistent provision therein or in any other manner which Allied may deem
necessary or desirable and which will not adversely affect the interests of the
holders in any material respect.
 
                              PLAN OF DISTRIBUTION
 
     Allied or AWNA may sell Securities to or through one or more underwriters
or dealers and also may sell Securities directly to institutional investors or
other purchasers, or through agents.
 
     The distribution of the Securities may be effected from time to time in one
or more transactions at a fixed price or prices, which may be changed, or at
market prices prevailing at the time of sale, at prices related to such
prevailing market prices or at negotiated prices.
 
     In connection with the sale of Securities, underwriters or agents may
receive compensation from Allied or AWNA or from purchasers of Securities for
whom they may act as agents in the form of discounts, concessions or
commissions. Underwriters may sell Securities to or through dealers, and such
dealers may receive compensation in the form of discounts, concessions or
commissions from the underwriters and/or commissions from the purchasers for
whom they may act as agents. Underwriters, dealers and agents that participate
in the distribution of Securities may be deemed to be underwriters, and any
discounts or commissions received by them from Allied and any profit on the
resale of Securities by them may be deemed to be underwriting discounts and
commissions, under the Securities Act. Any such underwriter or agent will be
identified, and any such compensation received from Allied or AWNA will be
described, in the related Prospectus Supplement.
 
     Under agreements which may be entered into by Allied and/or AWNA,
underwriters and agents who participate in the distribution of Securities may be
entitled to indemnification by Allied and AWNA against certain liabilities,
including liabilities under the Securities Act.
 
     If so indicated in the related Prospectus Supplement, Allied or AWNA will
authorize underwriters or other persons acting as Allied's or AWNA's agents to
solicit offers by certain institutions to purchase Securities from Allied or
AWNA pursuant to contracts providing for payment and delivery on a future date.
Institutions with which such contracts may be made include commercial and
savings banks, insurance companies, pension funds, investment companies,
educational and charitable institutions and others, but in all cases such
institutions must be approved by Allied or AWNA. The obligations of any
purchaser under any such contract will be subject to the condition that the
purchase of the Securities shall not at the time of delivery be prohibited under
the laws of the jurisdiction to which such purchaser is subject. The
underwriters and such other agents will not have any responsibility in respect
of the validity or performance of such contracts.
 
     Certain of the underwriters or agents and their associates may engage in
transactions with and perform services for Allied, AWNA or their respective
affiliates in the ordinary course of their respective businesses.
 
     The Securities may or may not be listed on a national securities exchange
or Nasdaq (other than the Common Stock, which is listed on the Nasdaq National
Market tier of Nasdaq). Any Common Stock sold pursuant to a Prospectus
Supplement will be listed on the Nasdaq National Market tier of Nasdaq. No
assurances can be given that there will be an active trading market for the
Securities.
 
                             VALIDITY OF SECURITIES
 
     The validity of the Securities will be passed upon for Allied and AWNA by
Fried, Frank, Harris, Shriver & Jacobson, a partnership including professional
corporations, New York, New York, and for the underwriters, dealers or agents,
if any, by Sullivan & Cromwell, New York, New York.

ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
     Section 145 of the Delaware General Corporation Law permits a corporation
to indemnify any 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, by reason of the fact
that he is or was a director, officer, employee or agent of the corporation or
is or was serving at the request of the corporation as a director, officer,
employee or agent of another corporation, partnership, joint venture, trust or
other enterprise against expenses, judgments, fines and amounts paid in
settlement actually and reasonably incurred by him in connection with such
action. In an action brought to obtain a judgment in the corporation's favor,
whether by the corporation itself or derivatively by a stockholder, the
corporation may only indemnify for expenses, including attorney's fees, actually
and reasonably incurred in connection with the defense or settlement of such
action, and the corporation may not indemnify for amounts paid in satisfaction
of a judgment or in settlement of the claim. In any such action, no
indemnification may be paid in respect of any claim, issue or matter as to which
such person shall have been adjudged liable to the corporation except as
otherwise approved by the Delaware Court of Chancery or the court in which the
claim was brought. In any other type of proceeding, the indemnification may
extend to judgments, fines and amounts paid in settlement, actually and
reasonably incurred in connection with such other proceeding, as well as to
expenses.
 
     The statute does not permit indemnification unless the person seeking
indemnification has acted in good faith and in a manner reasonably believed to
be in, or not opposed to, the best interests of the corporation and, in the case
of criminal actions or proceedings, the person had no reasonable cause to
believe his conduct was unlawful. The statute contains additional limitations
applicable to criminal actions and to actions brought by or in the name of the
corporation. The determination as to whether a person seeking indemnification
has met the required standard of conduct is to be made (1) by a majority vote of
a quorum of disinterested members of the board of directors, (2) by independent
legal counsel in a written opinion, if such a quorum does not exist or if the
disinterested directors so direct, or (3) by the stockholders.
 
     Allied's Certificate of Incorporation and Bylaws require Allied to
indemnify its directors to the fullest extent permitted under Delaware law.
Pursuant to employment agreements entered into by Allied with its executive
officers and certain other key employees, Allied must indemnify such officers
and employees in the same manner and to the same extent that Allied is required
to indemnify its directors under Allied's Bylaws. Allied's Certificate limits
the personal liability of a director to the corporation or its stockholders to
damages for breach of the director's fiduciary duty.

     Allied has purchased insurance on behalf of its directors and officers
against certain liabilities that may be asserted against, or incurred by, such
persons in their capacities as directors or officers of the registrant, or that
may arise out of their status as directors or officers of the registrant,
including liabilities under the federal and state securities laws. Allied has
entered into indemnification agreements to indemnify its directors to the extent
permitted under Delaware law.

ITEM 17.  UNDERTAKINGS
 
     (a) The undersigned Allied and AWNA (the "Registrants") hereby undertake:
 
          (1) To file, during any period in which offers or sales are being
     made, a post-effective amendment to this registration statement:
 
             (i) To include any prospectus required by Section 10(a)(3) of the
        Securities Act of 1933;
 
             (ii) To reflect in the prospectus any facts or events arising after
        the effective date of this Registration Statement (or the most recent
        post-effective amendment thereof) which, individually or in the
        aggregate, represent a fundamental change in the information set forth
        in this Registration Statement. Notwithstanding the foregoing, any
        increase or decrease in volume of securities offered (if the total
        dollar value of securities offered would not exceed that which was
        registered) and any deviation from the low or high end of the estimated
        maximum offering range may be reflected in the form of prospectus filed
        with the Commission pursuant to Rule 424(b) if, in the aggregate, the
        changes in volume and price represent no more than a 20% change in the
        maximum aggregate offering price set forth in the "Calculation of
        Registration Fee" table in the effective registration statement; and
 
             (iii) To include any material information with respect to the plan
        of distribution not previously disclosed in this Registration Statement
        or any material change to such information in this Registration
        Statement;
 
     provided, however, that the undertakings set forth in paragraphs (1) (i)
     and (ii) above do not apply if the information required to be included in a
     post-effective amendment by those paragraphs is contained in periodic
     reports filed by the Registrants pursuant to Section 13 or Section 15(d) of
     the Securities Exchange Act of 1934 that are incorporated by reference in
     this Registration Statement.
 
          (2) That, for the purpose of determining any liability under the
     Securities Act of 1933, each such post-effective amendment shall be deemed
     to be a new registration statement relating to the securities offered
     therein, and the offering of such securities at that time shall be deemed
     to be the initial bona fide offering thereof.
 
          (3) To remove from registration by means of a post-effective amendment
     any of the securities being registered which remain unsold at the
     termination of the offering.
 
     (b) Each of the undersigned Registrants hereby undertakes that, for
purposes of determining any liability under the Securities Act of 1933, each
filing of Allied's annual report pursuant to Section 13(a) or Section 15(d) of
the Securities Exchange Act of 1934 that is incorporated by reference in this
Registration Statement shall be deemed to be a new registration statement
relating to the securities offered herein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.
 
     (c) Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the Registrants pursuant to the provisions permitted under Item 15 above or
otherwise, the Registrants have been advised that in the opinion of the
Securities and Exchange Commission such indemnification is against public policy
as expressed in the Securities Act of 1933 and is, therefore, unenforceable. In
the event that a claim for indemnification against such liabilities (other than
the payment by the Registrants of expenses incurred or paid by a director,
officer or controlling person of the Registrants in the successful defense of
any action, suit or proceeding) is asserted against the Registrants by such
director, officer or controlling person in connection with the securities being
registered hereby, the Registrants will, unless in the opinion of their counsel
the matter has been settled by controlling precedent, submit to a court of
appropriate jurisdiction the question whether such indemnification by them is
against public policy as expressed in the Securities Act of 1933 and will be
governed by the final adjudication of such issue.

     (d) Each of the undersigned Registrants hereby undertakes that:
 
          (1) For purposes of determining any liability under the Securities Act
     of 1933, 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 Registrants pursuant to Rule 424(b)(1) or
     (4) or 497(h) under the Securities Act of 1933 shall be deemed to be part
     of this Registration Statement as of the time it was declared effective.
 
          (2) For the purpose of determining any liability under the Securities
     Act of 1933, 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.
 
     (e) Each of the undersigned Registrants hereby undertakes to file an
application for the purpose of determining the eligibility of each of the
Trustees to act under subsection (a) of Section 310 of the Trust Indenture Act
in accordance with the rules and regulations prescribed by the Commission under
Section 305(b)(2) of the Trust Indenture Act.

                  Section 1.3. Form of Documents Delivered to Trustee . In any
case where several matters are required to be certified by, or covered by an
opinion of, any specified Person, it is not necessary that all such matters be
certified by, or covered by the


                                       11
<PAGE>   20
opinion of, only one such Person, or that they be so certified or covered by
only one document, but one such Person may certify or give an opinion with
respect to some matters and one or more other such Persons as to other matters,
and any such Person may certify or give an opinion as to such matters in one or
several documents.

                  Any certificate or opinion of an officer of the Company may be
based, insofar as it relates to legal matters, upon a certificate or opinion of,
or representations by, counsel, unless such officer knows, or in the exercise of
reasonable care should know, that the certificate or opinion or representations
with respect to the matters upon which his or her certificate or opinion is
based are erroneous. Any such certificate or opinion or any Opinion of Counsel
may be based, insofar as it relates to factual matters, upon a certificate or
opinion of, or representations by, an officer or officers of the Company stating
that the information with respect to such factual matters is in the possession
of the Company, unless such officer or counsel knows, or in the exercise of
reasonable care should know, that the certificate or opinion or representations
as to such matters are erroneous.

                  Any certificate, statement or opinion of an officer of the
Company or of counsel may be based, insofar as it relates to accounting matters,
upon a certificate or opinion of or representations by an accountant or firm of
accountants in the employ of the Company, unless such officer or counsel, as the
case may be, knows, or in the exercise of reasonable care should know, that the
certificate or opinion or representations with respect to the accounting matters
upon which his certificate, statement or opinion is based are erroneous.

                  Where any Person is required to make, give or execute two or
more applications, requests, consents, certificates, statements, opinions or
other instruments under this Indenture, they may, but need not, be consolidated
and form one instrument.

                  Section 1.4. Acts of Holders . (a) Any request, demand,
authorization, direction, notice, consent, waiver or other action provided by
this Indenture to be given or taken by Holders may be embodied in and evidenced
by one or more instruments of substantially similar tenor signed (either
physically or by means of a facsimile or an electronic transmission, provided,
in the case of an electronic transmission, that it is transmitted through the
facilities of a Depositary) by such Holders in person or by agent or proxy duly
appointed in writing. If Securities of a series are issuable as Bearer
Securities, any request, demand, authorization, direction, notice, consent,
waiver or other action provided by this Indenture to be given or taken by
Holders of Securities of such series may, alternatively, be embodied in and
evidenced by the record of Holders of Securities of such series voting in favor
thereof pursuant to the third paragraph of Section 13.4, either in person or by
proxies duly appointed in writing, at any meeting of Holders of Securities of
such series duly called and held in accordance with the provisions of


                                       12
<PAGE>   21
Article 13, or a combination of such instruments and any such record. Except as
herein otherwise expressly provided, such action shall become effective when
such instrument or instruments or record or both are received (either physically
or by means of a facsimile or an electronic transmission, provided, in the case
of an electronic transmission, that it is transmitted through the facilities of
a Depositary) by the Trustee and, where it is hereby expressly required, to the
Company. Such instrument or instruments and record (and the action embodied
therein and evidenced thereby) are herein sometimes referred to as the "Act" of
the Holders signing such instrument or instruments or, in the case of Holders of
Securities of a series issuable as Bearer Securities, so voting at such meeting.
The Company and the Trustee may assume that any Act of a Holder has not been
modified or revoked unless written notice to the contrary is received prior to
the time that the action to which such Act relates has become effective. Proof
of execution of any such instrument or of a writing appointing any such agent
shall be sufficient for any purpose of this Indenture and (subject to Section
315 of the Trust Indenture Act) conclusive in favor of the Trustee and the
Company, if made in the manner provided in this Section. The record of any
meeting of Holders of Securities issuable as Bearer Securities shall be proved
in the manner provided in Section 13.6.

                  (b)    The fact and date of the execution by any Person of
any such instrument or writing and the authority of the Person executing the
same may be proved in any manner which the Trustee deems sufficient.

                  (c)    The ownership of Bearer Securities may be proved by
the production of such Bearer Securities or by a certificate executed by any
trust company, bank, banker or other depository, wherever situated, if such
certificate shall be deemed by the Trustee to be satisfactory, showing that at
the date therein mentioned such Person had on deposit with such trust company,
bank, banker or other depository, or exhibited to it, the Bearer Securities
therein described; or such facts may be proved by the certificate or affidavit
of the Person holding such Bearer Securities, if such certificate or affidavit
is deemed by the Trustee to be satisfactory. The Trustee and the Company may
assume that such ownership of any Bearer Security continues until (i) another
such certificate or affidavit bearing a later date issued in respect of the same
Bearer Security is produced, (ii) such Bearer Security is produced to the
Trustee by some other Person, (iii) such Bearer Security is surrendered in
exchange for a Registered Security or (iv) such Bearer Security is no longer
Outstanding. The ownership of Bearer Securities may also be proved in any other
manner which the Trustee deems sufficient.

                  (d)     The ownership of Registered Securities shall be
proved by the Register.

                  (e)     Any request, demand, authorization, direction,
notice, consent, waiver or other Act of the Holder of any Security shall bind
every future Holder of the

                                       13
<PAGE>   22
same Security and any interest coupons appertaining thereto and the Holder of
every Security or interest coupon 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 Act is made upon such Security or
interest coupon.

                  (f)     If the Company shall solicit from the Holders any
request, demand, authorization, direction, notice, consent, waiver or other Act,
the Company may, at its option, by or pursuant to a Board Resolution, fix in
advance a record date for the determination of Holders of Registered Securities
entitled to give such request, demand, authorization, direction, notice,
consent, waiver or other Act, but the Company shall have no obligation to do so.
Notwithstanding Section 316(c) of the Trust Indenture Act, any such record date
shall be the record date specified in or pursuant to such Board Resolution,
which shall be a date not more than 30 days prior to the first solicitation of
Holders generally in connection therewith and no later than the date such first
solicitation is completed. If such a record date is fixed, such request, demand,
authorization, direction, notice, consent, waiver or other Act may be given
before or after such record date, but only the Holders of Registered Securities
of record at the close of business on such record date shall be deemed to be
Holders for the purposes of determining whether Holders of the requisite
proportion of Outstanding Securities have authorized or agreed or consented to
such request, demand, authorization, direction, notice, consent, waiver or other
Act, and for that purpose the Outstanding Securities shall be computed as of
such record date; provided that no such authorization, agreement or consent by
the Holders on such record date shall be deemed effective unless it shall become
effective pursuant to the provisions of this Indenture not later than six months
after the record date.

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

                  Section 1.5. Notices, Etc., to Trustee and 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,

                  (1) 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 Department, or at any other address previously furnished in
writing to the Holders or the Company by the Trustee, or, with respect to
notices by the Company, transmitted by facsimile transmis-


                                       14
<PAGE>   23
sion (confirmed by guaranteed overnight courier) to the following facsimile
number: (612) 244-0711 or to any other facsimile number previously furnished in
writing to the Company by the Trustee, or

                  (2) 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 it addressed
to it at the address of the Company's 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 or, with respect to notices by the
Trustee, transmitted by facsimile transmission (confirmed by guaranteed
overnight courier) to the following facsimile number: (602) 423-9424 or to any
other facsimile number previously furnished in writing to the Trustee by the
Company.

                  Section 1.6. Notice to Holders; Waiver . Where this Indenture
provides for notice to Holders of any event, (i) if any of the Securities
affected by such event are Registered Securities, such notice to the Holders
thereof shall be sufficiently given (unless otherwise herein expressly provided)
if in writing and mailed, first-class postage prepaid, to each such Holder
affected by such event, at his or her address as it appears in the Register,
within the time prescribed for the giving of such notice, and (ii) if any of the
Securities affected by such event are Bearer Securities, notice to the Holders
thereof shall be sufficiently given (unless otherwise herein or in the terms of
such Bearer Securities expressly provided) if published once in an Authorized
Newspaper in New York, New York, and in such other city or cities, if any, as
may be specified as contemplated by Section 3.1. Such notices shall be deemed to
have been given on the date of such mailing or publication.

                  In any case where notice to Holders is given by mail or by
publication, neither the failure to mail or publish such notice, nor any defect
in any notice so mailed or published, to any particular Holder shall affect the
sufficiency of such notice with respect to other Holders of Registered
Securities or of Bearer Securities. Any notice mailed to a Holder in the manner
herein prescribed shall be conclusively deemed to have been received by such
Holder, whether or not such Holder actually receives such notice.

                  If by reason of the suspension of regular mail service or by
reason of any other cause it shall be impracticable to give such notice as
provided above, then such notification as shall be made with the approval of the
Trustee shall constitute a sufficient notification for every purpose hereunder.
If it is impossible or, in the opinion of the Trustee, impracticable to give any
notice by publication in the manner herein required, then such publication in
lieu thereof as shall be made with the approval of the Trustee shall constitute
a sufficient publication of such notice.


                                       15
<PAGE>   24
                  Any request, demand, authorization, direction, notice, consent
or waiver required or permitted under this Indenture shall be in the English
language, except that any published notice may be in an official language of the
country of publication.

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

                  Section 1.7. Headings and Table of Contents . The Article and
Section headings herein and the Table of Contents are for convenience only and
shall not affect the construction hereof.

                  Section 1.8. Successor and Assigns . All covenants and
agreements in this Indenture by the Company shall bind its successors and
assigns, whether so expressed or not.

                  Section 1.9. Separability . In case any provision of this
Indenture or the Securities 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 1.10. Benefits of Indenture . Nothing in this
Indenture or in the Securities, expressed or implied, shall give to any Person,
other than the parties hereto and their successors hereunder and the Holders,
any benefit or any legal or equitable right, remedy or claim under this
Indenture.

                  Section 1.11. Incorporators, Stockholders, Officers and
Directors of the Company Exempt from Individual Liability . No recourse under or
upon any obligation, covenant or agreement of or contained in this Indenture or
of or contained in any Security or interest coupon appertaining thereto, or for
any claim based thereon or otherwise in respect thereof, or because of any
indebtedness represented thereby, shall be had against any incorporator,
stockholder, officer or director, as such, past, present or future, of the
Company or any successor Person, either directly or through the Company or any
successor Person, whether by virtue of any constitution, statute or rule of law,
by the enforcement of any assessment or penalty, by any legal or equitable
proceeding or otherwise; it being expressly understood that all such liability
is hereby expressly waived


                                       16

and released as a condition of the acceptance of, and as a part of the
consideration for the execution of this Indenture and the issuance of, the
Securities and any interest coupons appertaining thereto.

                  Section 1.12. Governing Law; Conflict with Trust Indenture 
Act. THIS INDENTURE, THE SECURITIES AND ANY INTEREST COUPONS APPERTAINING
THERETO SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE
STATE OF NEW YORK. This Indenture is subject to the Trust Indenture Act and if
any provision hereof limits, qualifies or conflicts with the Trust Indenture
Act, the Trust Indenture Act shall control. Whether or not this Indenture is
required to be qualified under the Trust Indenture Act, the provisions of the
Trust Indenture Act required to be included in an indenture in order for such
indenture to be so qualified shall be deemed to be included in this Indenture
with the same effect as if such provisions were set forth herein and any
provisions hereof which may not be included in an indenture which is so
qualified shall be deemed to be deleted or modified to the extent such
provisions would be required to be deleted or modified in an indenture so
qualified.

                  Section 1.13. Legal Holidays. In any case where any Interest
Payment Date, Redemption Date, sinking fund payment date, Stated Maturity or
Maturity of any Security shall not be a Business Day at any Place of Payment,
then (notwithstanding any other provision of this Indenture or of any Security
or interest coupon other than a provision in the Securities of any series which
specifically states that such provision shall apply in lieu of this Section),
payment of principal, premium, if any, or interest need not be made at such
Place of Payment on such date, but may be made on the next succeeding Business
Day at such Place of Payment with the same force and effect as if made on such
date; provided that no interest shall accrue on the amount so payable for the
period from and after such Interest Payment Date, Redemption Date, sinking fund
payment date, Stated Maturity or Maturity, as the case may be, if such amount is
so paid on the next succeeding Business Day.

                  Section 1.14. Moneys of Different Currencies to Be 
Segregated. The Trustee shall segregate all moneys, funds and accounts held by
the Trustee hereunder in one currency from any moneys, funds and accounts held
by the Trustee hereunder in one currency from any moneys, funds or accounts in
any other currencies, notwithstanding any provision herein which would otherwise
permit the Trustee to commingle such amounts.

                  Section 1.15. Independence of Covenants. All covenants and
agreements in this Indenture shall be given independent effect so that if a
particular action or condition is not permitted by any such covenant, the fact
that it would be permitted by an exception to, or be otherwise within the
limitations of, another covenant shall not avoid


                                       17
<PAGE>   26
the occurrence of a Default or an Event of Default if such action is taken or
condition exists.

                  Section 1.16. Counterparts. This Indenture may be executed in
any number of counterparts, each of which shall be an original, but such
counterparts shall together constitute but one and the same instrument.

Resolution or in one or more indentures supplemental hereto, in each case with
such appropriate insertions, omissions, substitutions and other variations as
are required or permitted by this Indenture, and may have such letters, numbers
or other marks of identification and such legends or endorsements placed thereon
as may be required to comply with the rules of any applicable securities
exchange, organizational document, governing instrument or law or as may,
consistently herewith, be determined by the officers executing such Securities
and interest coupons, if any, as evidenced by their execution of the Securities
and interest coupons, if any. If temporary Securities of any series are issued
as permitted by Section 3.4, the form thereof also shall be established as
provided in the preceding sentence. If the forms of Securities and interest
coupons, if any, of any series are established by, or by action taken pursuant
to, a Board Resolution, a copy of the Board Resolution together with an
appropriate record of any such action taken pursuant thereto, including a copy
of the approved form of Securities or interest coupons, if any, shall be
delivered to the Trustee at or prior to the delivery of the Company Order
contemplated by Section 3.3 for the authentication and delivery of such
Securities.

                  Unless otherwise specified as contemplated by Section 3.1,
Bearer Securities shall have interest coupons attached.

exchange, any other manner permitted by the rules of such securities exchange),

                  Section 2.3. Securities in Global Form. If Securities of or
within a series are issuable in whole or in part in global form, any such
Security may provide that it shall represent the aggregate or specified amount
of Outstanding Securities from time to time endorsed thereon and may also
provide that the aggregate amount of Outstanding Securities represented thereby
may from time to time be reduced or increased to reflect exchanges. Any
endorsement of a Security in global form to reflect the amount, or any increase
or decrease in the amount, or changes in the rights of Holders, of Outstanding
Securities represented thereby, shall be made in such manner and by such Person
or Persons as shall be specified therein or in the Company Order to be delivered
to the Trustee pursuant to Section 3.3 or 3.4. Subject to the provisions of
Section 3.3, Section 3.4, if applicable, and Section 3.5, the Trustee shall
deliver and redeliver any Security in permanent global form in the manner and
upon instructions given by the Person or Persons specified therein or in the
applicable Company Order. Any instructions by the Company with respect to
endorsement or delivery or redelivery of a Security in global form shall be in
writing but need not comply with Section 1.2 hereof and need not be accompanied
by an Officers' Certificate or an Opinion of Counsel.

                  The provisions of the last paragraph of Section 3.3 shall
apply to any Security in global form if such Security was never issued and sold
by the Company and the Company delivers to the Trustee the Security in global
form together with written instructions (which need not comply with Section 1.2
hereof and need not be accompanied by an Officers' Certificate or an Opinion of
Counsel) with regard to the reduction in the principal amount of Securities
represented thereby, together with the written statement contemplated by the
last paragraph of Section 3.3.

                  Notwithstanding the provisions of Section 2.1 and 3.7, unless
otherwise specified as contemplated by Section 3.1, payment of principal of,
premium, if any, and interest on any Registered Security in permanent global
form shall be made to the registered holder thereof.

                  Section 2.4. Form of Legend for Securities in Global Form.

OR BY THE DEPOSITARY OR ANY SUCH NOMINEE TO A SUCCESSOR DEPOSITARY OR A NOMINEE

exchange Securities of the series into or for Equity Securities of the Company
or other securities or property of the Company;
    

   
                  (27) whether the Securities are secured or unsecured, and if
secured, the Security and related terms in connection therewith; and
    

   
                  (28) any other terms of the series (which terms shall not be
inconsistent with the provisions of this Indenture) including any terms which
may be required by or advisable under United States laws or regulations or
advisable (as determined by the Company) in connection with the marketing of
Securities of the series.
    

                  (c) All Securities of any one series and interest coupons, if
any, appertaining thereto shall be substantially identical except as to
denomination and except as may otherwise be provided (i) by a Board Resolution,
(ii) by action taken pursuant to a Board Resolution and (subject to Section 3.3)
set forth, or determined in the manner provided, in the related Officers'
Certificate or (iii) in an indenture supplemental hereto. All Securities of any

additional Securities of such series.

                  (d) If any of the terms of the Securities of any series are
established by action taken pursuant to a Board Resolution, a copy of such Board
Resolution shall be delivered to the Trustee at or prior to the delivery of the
Officers' Certificate setting forth, or providing the manner for determining,
the terms of the Securities of such series, and an appropriate record of any
action taken pursuant thereto in connection with the issuance of any Securities
of such series shall be delivered to the Trustee prior to the authentication and
delivery thereof.

   
                  Section 3.2. Denominations. Unless otherwise provided as
contemplated by Section 3.1, any Registered Securities of a series denominated
in Dollars shall be issuable in denominations of U.S. $1,000 and any integral
multiple thereof and any Bearer Securities of a series denominated in Dollars
shall be issuable in the denomination of U.S. $5,000 and any integral multiple
thereof. Securities denominated in a Foreign Currency shall be issuable in such
denominations as are established with respect to such Securities in or pursuant
to this Indenture.
    

                  Section 3.3. Execution, Authentication, Delivery and Dating.
Securities shall be executed on behalf of the Company by the Chairman of the
Board, the President, the Chief Executive Officer, the Chief Operating Officer,
the Chief Financial Officer or any Vice President of the Company, and need not
be attested. The Company's seal shall be reproduced on the Securities. The
signatures of any of these officers on the Securities may be manual or
facsimile. The interest coupons, if any, of Bearer Securities shall bear the
facsimile signature of the Chairman of the Board, the President, the Chief
Executive

                                       24

Officer, the Chief Operating Officer, the Chief Financial Officer or any Vice
President of the Company, and need not be attested.

                  Securities and interest coupons bearing the manual or
facsimile signatures of individuals who were at any time Officers of the Company
shall bind the Company, notwithstanding that such individuals or any of them
have ceased to be Officers prior to the authentication and delivery of such
Securities or were not Officers at the date of such Securities.

                  At any time and from time to time, the Company may deliver
Securities, together with any interest coupons appertaining thereto, of any
series executed by the Company to the Trustee for authentication, together with
a Company Order for the authentication and delivery of such Securities, and the
Trustee in accordance with such Company Order shall authenticate and deliver
such Securities to or upon the order of the Company (as set forth in such
Company Order); provided, however, that, in the case of Securities of a series
offered in a Periodic Offering, the Trustee shall authenticate and deliver such
Securities from time to time in accordance with such other procedures
(including, without limitation, the receipt by the Trustee of oral or electronic
instructions from the Company or its duly authorized agents, promptly confirmed
in writing) acceptable to the Trustee as may be specified by or pursuant to a
Company Order delivered to the Trustee prior to the time of the first
authentication of Securities of such series.

                  If the form or terms of the Securities of a series have been
established by or pursuant to one or more Board Resolutions or one or more
indentures supplemental hereto as permitted by Sections 2.1 and 3.1, in
authenticating such Securities and accepting the additional responsibilities
under this Indenture in relation to such Securities, the Trustee shall be
entitled to receive, and (subject to section 315(a) through (d) of the Trust
Indenture Act) shall be fully protected in relying upon,

                  (i) an Opinion of Counsel stating:

                  (1) if the form or forms of such Securities and any interest
coupons have been established by or pursuant to a Board Resolution as permitted
by Section 2.1, that such forms have been established in conformity with the
provisions of this Indenture;

                  (2) if the terms of such Securities and any interest coupons
have been, or, in the case of Securities of a series offered in a Periodic
Offering, will be, established by or pursuant to a Board Resolution as permitted
by Section 3.1, that such terms have been, or, in the case of Securities of a
series offered in a Periodic Offering, will be, established in conformity with
the provisions of this Indenture, subject, in the case of


                                       25
<PAGE>   34
Securities offered in a Periodic Offering, to any conditions specified in such
Opinion of Counsel;

                  (3) if the form or terms of such Securities have been
established in an indenture supplemental hereto, that such supplemental
indenture has been duly authorized, executed and delivered by the Company and,
when duly authorized, executed and delivered by the Trustee, will constitute a
legal, valid and binding obligation enforceable against the Company in
accordance with its terms, subject to (i) bankruptcy, insolvency, fraudulent
transfer, reorganization, moratorium and other similar laws of general
applicability relating to or affecting the enforcement of creditors' rights and
to general principles of equity (regardless of whether enforcement is sought in
a proceeding in equity or at law), and (ii) such other reasonable exceptions as
may be specified in such Opinion of Counsel; and

                  (4) that such Securities, together with any interest coupons
appertaining thereto, when issued by the Company and authenticated and delivered
by the Trustee in the manner and subject to any conditions specified in such
Opinion of Counsel, will constitute valid and legally binding obligations of the
Company, enforceable against the Company in accordance with their terms, subject
to (i) bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium
and other similar laws of general applicability relating to or affecting the
enforcement of creditors' rights and to general equity principles (regardless of
whether enforcement is sought in a proceeding in equity or at law) and except
further as enforcement thereof may be limited by (A) requirements that a claim
with respect to any Securities denominated other than in Dollars (or a Foreign
Currency or currency unit judgment in respect of such claim) be converted into
Dollars at a rate of exchange prevailing on a date determined pursuant to
applicable law or (B) governmental authority to limit, delay or prohibit the
making of payments in Foreign Currencies or currency units or payments outside
the United States, and (ii) such other reasonable exceptions as may be specified
in such Opinion of Counsel; and

                  (ii) an Officers' Certificate stating that all conditions
precedent provided for in this Indenture relating to the issuance of such
Securities have been complied with and that, to the knowledge of the signers of
such certificate, no Event of Default with respect to such Securities shall have
occurred and be continuing.

                  Notwithstanding that such form or terms have been so
established, the Trustee shall have the right to decline to authenticate such
Securities if, in the opinion of the Trustee (after consultation with counsel),
the issue of such Securities pursuant to this Indenture will materially
adversely affect the Trustee's own rights, duties or immunities under this
Indenture or otherwise or if the Trustee determines that such authentication may
not lawfully be made.

<PAGE>   35
                  Notwithstanding the provisions of Section 3.1 and of the two
preceding paragraphs, if all of the Securities of any series are not to be
issued at one time, it shall not be necessary to deliver the Officers'
Certificate otherwise required pursuant to Section 3.1 or the Company Order and
Opinion of Counsel otherwise required pursuant to the two preceding paragraphs
in connection with the authentication of each Security of such series if such
documents, with appropriate modifications to cover such future issuances, are
delivered at or prior to the authentication upon original issuance of the first
Security of such series to be issued.

                  With respect to Securities of a series offered in a Periodic
Offering, the Trustee may rely, as to the authorization by the Company of any of
such Securities, the form and terms thereof and the legality, validity, binding
effect and enforceability thereof, upon the Opinion of Counsel and the other
documents delivered pursuant to Sections 2.1 and 3.1 and this Section, as
applicable, in connection with the first authentication of Securities of such
series.

                  If the Company shall establish pursuant to Section 3.1 that
the Securities of a series are to be issued in whole or in part in global form,
then the Company shall execute and the Trustee shall, in accordance with this
Section and the Company Order with respect to such series, authenticate and
deliver one or more Securities in global form that (i) shall represent and shall
be denominated in an amount equal to the aggregate principal amount of the
Outstanding Securities of such series to be represented by such Security or
Securities in global form, (ii) shall be registered, if a Registered Security,
in the name of the Depositary for such Security or Securities in global form or
the nominee of such Depositary, (iii) shall be delivered by the Trustee to such
Depositary or pursuant to such Depositary's instruction and (iv) shall bear the
legend set forth in Section 2.4.

                  Each Depositary designated pursuant to Section 3.1 for a
Registered Security in global form must, at the time of its designation and at
all times while it serves as Depositary, be a clearing agency registered under
the Securities Exchange Act of 1934 and any other applicable statute or
regulation. If requested by the Company, the Trustee shall enter into an
agreement with a Depositary governing the respective duties and rights of such
Depositary and the Trustee with regard to Securities issued in global form.

                  Each Registered Security shall be dated the date of its
authentication and each Bearer Security shall be dated as of the date specified
pursuant to Section 3.1.

                  No Security or interest coupon appertaining thereto shall be
entitled to any benefits under this Indenture or be valid or obligatory for any
purpose until authenticated by the manual signature of one of the authorized
signatories of the Trustee or an Authenticating Agent and no interest coupon
shall be valid until the Security to which it appertains has been so
authenticated. Such signature upon any Security shall be


                                       27
<PAGE>   36
conclusive evidence, and the only evidence, that such Security has been duly
authenticated and delivered under this Indenture and is entitled to the benefits
of this Indenture. Except as permitted by Section 3.6 or 3.7, the Trustee shall
not authenticate and deliver any Bearer Security unless all appurtenant interest
coupons for interest then matured have been detached and cancelled.

                  Notwithstanding the foregoing, if any Security shall have been
authenticated and delivered hereunder but never issued and sold by the Company,
and the Company shall deliver such Security to the Trustee for cancellation as
provided in Section 3.9 together with a written statement (which need not comply
with Section 1.2 hereof and need not be accompanied by an Officers' Certificate
or an Opinion of Counsel) stating that such Security has never been issued and
sold by the Company, for all purposes of this Indenture such Security shall be
deemed never to have been authenticated and delivered hereunder and shall not be
entitled to the benefits of this Indenture.

                  Section 3.4. Temporary Securities. Pending the preparation of
definitive Securities of any series, the Company may execute and, upon Company
Order, the Trustee shall authenticate and deliver temporary Securities of such
series which are printed, lithographed, typewritten, mimeographed or otherwise
produced, in any authorized denomination, substantially of the tenor and form,
with or without interest coupons, of the definitive Securities in lieu of which
they are issued and with such appropriate insertions, omissions, substitutions
and other variations as the officers executing such Securities may determine, as
conclusively evidenced by their execution of such Securities and interest
coupons, if any. In the case of Securities of any series, such temporary
Securities may be in global form, representing all or a portion of the
Outstanding Securities of such series.

                  Except in the case of temporary Securities in global form,
each of which shall be exchanged in accordance with the provisions thereof, if
temporary Securities of any series are issued, the Company will cause definitive
Securities of such series to be prepared without unreasonable delay. After
preparation of definitive Securities of such series, the temporary Securities of
such series shall be exchangeable for definitive Securities of such series upon
surrender of the temporary Securities of such series at the office or agency of
the Company pursuant to Section 9.2 in a Place of Payment for such series,
without charge to the Holder. Upon surrender for cancellation of any one or more
temporary Securities of any series (accompanied by any unmatured interest
coupons appertaining thereto), the Company shall execute and the Trustee shall
authenticate and deliver in exchange therefor a like principal amount of
definitive Securities of the same series of authorized denominations and of like
tenor; provided, however, that no definitive Bearer Security shall be delivered
in exchange for a temporary Registered Security; and provided, further, that no
definitive Bearer Security shall be delivered in


                                       28
<PAGE>   37
exchange for a temporary Bearer Security unless such delivery shall occur only
outside the United States. Until so exchanged, the temporary Securities of any
series shall in all respects be entitled to the same benefits under this
Indenture as definitive Securities of such series except as otherwise specified
as contemplated by Section 3.1.

                  Section 3.5. Registration, Transfer and Exchange. The Company
shall cause to be kept at the Corporate Trust Office of the Trustee or in any
office or agency to be maintained by the Company in accordance with Section 9.2
in a Place of Payment a register (the "Register") in which, subject to such
reasonable regulations as it may prescribe, the Company shall provide for the
registration of Registered Securities and the registration of transfers of
Registered Securities. The Register shall be in written form or any other form
capable of being converted into written form within a reasonable time. The
Trustee is hereby initially appointed "Registrar" for the purpose of registering
Registered Securities and transfers of Registered Securities as herein provided.

                  Upon surrender for registration of transfer of any Registered
Security of any series at the office or agency maintained pursuant to Section
9.2 in a Place of Payment for that series, the Company shall execute, and the
Trustee shall authenticate and deliver, in the name of the designated transferee
or transferees, one or more new Registered Securities of the same series, of any
authorized denominations and of a like aggregate principal amount and tenor and
containing identical terms and provisions.

                  Bearer Securities (except for any temporary global Bearer
Securities) or any interest coupons appertaining thereto (except for interest
coupons attached to any temporary global Bearer Security) shall be transferable
by delivery.

                  At the option of the Holder, Registered Securities of any
series (except a Registered Security in global form) may be exchanged for other
Registered Securities of the same series, of any authorized denominations, of a
like aggregate principal amount and tenor and containing identical terms and
provisions, upon surrender of the Registered Securities to be exchanged at such
office or agency. Whenever any Registered Securities are so surrendered for
exchange, the Company shall execute, and the Trustee shall authenticate and
deliver, the Registered Securities which the Holder making the exchange is
entitled to receive. Unless otherwise specified as contemplated by Section 3.1,
Bearer Securities may not be issued in exchange for Registered Securities.

                  Unless otherwise specified as contemplated by Section 3.1, at
the option of the Holder, Bearer Securities of such series may be exchanged for
Registered Securities (if the Securities of such series are issuable in
registered form) or Bearer Securities (if Bearer Securities of such series are
issuable in more than one denomination and such exchanges are permitted by such
series) of the same series, of any authorized denominations, of like aggregate
principal amount and tenor and containing identical


                                       29
<PAGE>   38
terms and conditions, upon surrender of the Bearer Securities to be exchanged at
any such office or agency, with all unmatured interest coupons and all matured
interest coupons in default thereto appertaining. If the Holder of a Bearer
Security is unable to produce any such unmatured interest coupon or coupons or
matured interest coupon or coupons in default, such exchange may be effected if
the Bearer Securities are accompanied by payment in funds acceptable to the
Company and the Trustee in an amount equal to the face amount of such missing
interest coupon or coupons, or the surrender of such missing interest coupon or
interest coupons may be waived by the Company and the Trustee if there be
furnished to them such security or indemnity as they may require to save each of
them and any Paying Agent harmless. If thereafter the Holder of such Security
shall surrender to any Paying Agent any such missing interest coupon in respect
of which such a payment shall have been made, such Holder shall be entitled to
receive the amount of such payment; provided, however, that, except as otherwise
provided in Section 9.2, interest represented by interest coupons shall be
payable only upon presentation and surrender of those interest coupons at an
office or agency located outside the United States. Notwithstanding the
foregoing, in case any Bearer Security of any series is surrendered at any such
office or agency in exchange for a Registered Security of the same series after
the close of business at such office or agency on (i) any Regular Record Date
and before the opening of business at such office or agency on the relevant
Interest Payment Date, or (ii) any Special Record Date and before the opening of
business at such office or agency on the related date for payment of Defaulted
Interest, such Bearer Security shall be surrendered without the interest coupon
relating to such Interest Payment Date or proposed date of payment, as the case
may be (or, if such interest coupon is so surrendered with such Bearer Security,
such interest coupon shall be returned to the Person so surrendering the Bearer
Security), and interest or Defaulted Interest, as the case may be, will not be
payable on such Interest Payment Date or proposed date for payment, as the case
may be, in respect of the Registered Security issued in exchange for such Bearer
Security, but will be payable only to the Holder of such interest coupon, when
due in accordance with the provisions of this Indenture.

                  Notwithstanding anything herein to the contrary, the exchange
of Bearer Securities for Registered Securities shall be subject to applicable
laws and regulations in effect at the time of exchange. Neither the Company, the
Trustee nor the Registrar shall exchange any Bearer Securities for Registered
Securities if it has received an Opinion of Counsel that as a result of such
exchange the Company would suffer adverse consequences under the United States
Federal income tax laws and regulations then in effect and the Company has
delivered to the Trustee a Company Order directing the Trustee not to make such
exchanges thereafter, unless and until the Trustee receives a subsequent Company
Order to the contrary. The Company shall deliver copies of such Company Order to
the Registrar.

<PAGE>   39
                  Notwithstanding any other provision of this Section, unless
and until it is exchanged in whole or in part for Securities in certificated
form, a Security in global form representing all or a portion of the Securities
of a series may not be transferred except as a whole by the Depositary for such
series to a nominee of such Depositary or by a nominee of such Depositary to
such Depositary or another nominee of such Depositary or by such Depositary or
any such nominee to a successor Depositary for such series or a nominee of such
successor Depositary.

                  If at any time the Depositary for the Securities of a series
notifies the Company that it is unwilling or unable to continue as Depositary
for the Securities of such series or if at any time the Depositary for the
Securities of such series shall no longer be eligible under Section 3.3, the
Company shall appoint a successor Depositary with respect to the Securities of
such series. If a successor Depositary for the Securities of such series is not
appointed by the Company prior to the resignation of the Depositary and, in any
event, within 90 days after the Company receives such notice or becomes aware of
such ineligibility, the Company's designation of the Depositary pursuant to
Section 3.1(b)(23) shall no longer be effective with respect to the Securities
of such series and the Company shall execute, and the Trustee, upon receipt of a
Company Order for the authentication and delivery of certificated Securities of
such series of like tenor, shall authenticate and deliver, Securities of such
series of like tenor in certificated form, in authorized denominations and in an
aggregate principal amount equal to the principal amount of the Security or
Securities of such series of like tenor in global form in exchange for such
Security or Securities in global form.

                  The Company may at any time in its sole discretion determine
that Securities issued in global form shall no longer be represented by such a
Security or Securities in global form. In such event the Company shall execute,
and the Trustee, upon receipt of a Company Order for the authentication and
delivery of certificated Securities of such series of like tenor, shall
authenticate and deliver, Securities of such series of like tenor in
certificated form, in authorized denominations and in an aggregate principal
amount equal to the principal amount of the Security or Securities of such
series of like tenor in global form in exchange for such Security or Securities
in global form.

                  If specified by the Company pursuant to Section 3.1 with
respect to a series of Securities, the Depositary for such series may surrender
a Security in global form of such series in exchange in whole or in part for
Securities of such series in certificated form on such terms as are acceptable
to the Company and such Depositary. Thereupon, the Company shall execute, and
the Trustee shall authenticate and deliver, without service charge,

                           (i) to each Person specified by such Depositary a new
                  certificated Security or Securities of the same series of like
                  tenor, of any

                  authorized denomination as requested by such Person in
                  aggregate principal amount equal to and in exchange for such
                  Person's beneficial interest in the Security in global form;
                  and

                           (ii) to such Depositary a new Security in global form
                  of like tenor in a denomination equal to the difference, if
                  any, between the principal amount of the surrendered Security
                  in global form and the aggregate principal amount of
                  certificated Securities delivered to Holders thereof.

                  Upon the exchange of a Security in global form for Securities
in certificated form, such Security in global form shall be cancelled by the
Trustee. Unless expressly provided with respect to the Securities of any series
that such Security may be exchanged for Bearer Securities, Securities in
certificated form issued in exchange for a Security in global form pursuant to
this Section shall be registered in such names and in such authorized
denominations as the Depositary for such Security in global form, pursuant to
instructions from its direct or indirect participants or otherwise, shall
instruct the Trustee in writing. The Trustee shall deliver such Securities to
the Persons in whose names such Securities are so registered.

                  Whenever any Securities are surrendered for exchange, the
Company shall execute, and the Trustee shall authenticate and deliver, the
Securities which the Holder making the exchange is entitled to receive.

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

                  Every Registered Security presented or surrendered for
registration of transfer or for exchange shall (if so required by the Company,
the Registrar or the Trustee) be duly endorsed, or be accompanied by a written
instrument of transfer in form satisfactory to the Company, the Registrar and
the Trustee 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 for any exchange of Securities, 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 or transfer or exchange of
Securities, other than exchanges pursuant to Section 3.4 or 11.7 not involving
any transfer.

                  The Company shall not be required (i) to issue, register the
transfer of, or exchange any Securities for a period beginning at the opening of
business 15 days before any selection for redemption of Securities of like tenor
and of the series of which such


                                       32
<PAGE>   41
Security is a part and ending at the close of business on the earliest date on
which the relevant notice of redemption is deemed to have been given to all
Holders of Securities of like tenor and of such series to be redeemed; (ii) to
register the transfer of or exchange any Registered Security so selected for
redemption, in whole or in part, except the unredeemed portion of any Security
being redeemed in part; or (iii) to exchange any Bearer Security so selected for
redemption, except that such a Bearer Security may be exchanged for a Registered
Security of that series and like tenor; provided that such Registered Security
shall be simultaneously surrendered for redemption.

                  The foregoing provisions relating to registration, transfer
and exchange may be modified, supplemented or superseded with respect to any
series of Securities by a Board Resolution or in one or more indentures
supplemental hereto.

                  Section 3.6. Replacement Securities. If a mutilated Security
or a Security with a mutilated interest coupon appertaining to it is surrendered
to the Trustee, together with, in proper cases, such security or indemnity as
may be required by the Company or the Trustee to save each of them harmless, the
Company shall execute and the Trustee shall authenticate and deliver a
replacement Registered Security, if such surrendered Security was a Registered
Security, or a replacement Bearer Security with interest coupons corresponding
to the interest coupons appertaining to the surrendered Security, if such
surrendered Security was a Bearer Security, of the same series and date of
maturity.

                  If there shall be delivered to the Company and the Trustee (i)
evidence to their satisfaction of the destruction, loss or theft of any Security
or Security with a destroyed, lost or stolen interest coupon and (ii) such
security 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 Security or interest coupon has been acquired by a bona
fide purchaser, the Company shall execute and the Trustee shall authenticate and
deliver in lieu of any such destroyed, lost or stolen Security or in exchange
for the Security to which a destroyed, lost or stolen interest coupon appertains
(with all appurtenant interest coupons not destroyed, lost or stolen), a
replacement Registered Security, if such Holder's claim appertains to a
Registered Security, or a replacement Bearer Security with interest coupons
corresponding to the interest coupons appertaining to the destroyed, lost or
stolen Bearer Security or the Bearer Security to which such lost, destroyed or
stolen interest coupon appertains, if such Holder's claim appertains to a Bearer
Security, of the same series and principal amount, containing identical terms
and provisions and bearing a number not contemporaneously outstanding with
interest coupons corresponding to the interest coupons, if any, appertaining to
the destroyed, lost or stolen Security.

                  In case any such mutilated, destroyed, lost or stolen Security
or interest coupon has become or is about to become due and payable, the Company
in its discretion may, instead of issuing a new Security or interest coupon, pay
such Security or interest coupon; provided, however, that payment of principal
of and any premium or interest on Bearer Securities shall, except as otherwise
provided in Section 9.2, be payable only at an office or agency located outside
the United States and, unless otherwise specified as contemplated by Section
3.1, any interest on Bearer Securities shall be payable only upon presentation
and surrender of the interest coupons appertaining thereto.

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

                  Every new Security of any series with its interest coupons, if
any, issued pursuant to this Section in lieu of any destroyed, lost or stolen
Security, or in exchange for a Security to which a destroyed, lost or stolen
interest coupon appertains, shall constitute an original additional contractual
obligation of the Company, whether or not the destroyed, lost or stolen Security
and its interest coupon, if any, or the destroyed, lost or stolen interest
coupon, 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 Securities of that series and their interest coupons, if any, 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 Securities or
interest coupons.

                  Section 3.7. Payment of Interest; Interest Rights Preserved.
(a) Unless otherwise provided as contemplated by Section 3.1, interest, if any,
on any Registered Security which is payable, and is punctually paid or duly
provided for, on any Interest Payment Date shall be paid to the Person in whose
name that Security (or one or more Predecessor Securities) is registered at the
close of business on the Regular Record Date for such interest at the office or
agency maintained for such purpose pursuant to Section 9.2; provided, however,
that at the option of the Company, interest on any series of Registered
Securities that bear interest may be paid (i) by check mailed to the address of
the Person entitled thereto as it shall appear on the Register of Holders of
Securities of such series or (ii) at the expense of the Company, by wire
transfer to an account maintained by the Person entitled thereto as specified in
the Register of Holders of Securities of such series.

                  Unless otherwise provided as contemplated by Section 3.1, (i)
interest, if any, on Bearer Securities shall be paid only against presentation
and surrender of the


                                       34
<PAGE>   43
interest coupons for such interest installments as are evidenced thereby as they
mature and (ii) original issue discount, if any, on Bearer Securities shall be
paid only against presentation and surrender of such Securities; in either case
at the office of a Paying Agent located outside the United States, unless the
Company shall have otherwise instructed the Trustee in writing, provided that
any such instruction for payment in the United States does not cause any Bearer
Security to be treated as a "registration-required obligation" under United
States laws and regulations. The interest, if any, on any temporary Bearer
Security shall be paid, as to any installment of interest evidenced by an
interest coupon attached thereto only upon presentation and surrender of such
interest coupon and, as to other installments of interest, only upon
presentation of such Security for notation thereon of the payment of such
interest. If at the time a payment of principal of or interest, if any, on a
Bearer Security or interest coupon shall become due, the payment of the full
amount so payable at the office or offices of all the Paying Agents outside the
United States is illegal or effectively precluded because of the imposition of
exchange controls or other similar restrictions on the payment of such amount in
Dollars, then the Company may instruct the Trustee in writing to make such
payments at a Paying Agent located in the United States, provided that provision
for such payment in the United States would not cause such Bearer Security to be
treated as a "registration-required obligation" under United States laws and
regulations.

                  (b) Unless otherwise provided as contemplated by Section 3.1,
any interest on Securities of any series which is payable, but is not punctually
paid or duly provided for, on any Interest Payment Date in the case of
Registered Securities and upon presentation and surrender of the applicable
interest coupon in accordance with the second paragraph of Section 3.7(a) in the
case of Bearer Securities (herein called "Defaulted Interest"), shall forthwith
cease to be payable to the Holders on the relevant Regular Record Date by virtue
of their having been such Holders, and such Defaulted Interest may be paid by
the Company, at its election in each case, as provided in clause (1) or (2)
below:

                  (1) In the case of Registered Securities, the Company may
         elect to make payment of such Defaulted Interest to the Persons in
         whose names such Registered Securities (or their respective Predecessor
         Securities) are registered at the close of business on a Special Record
         Date for the payment of such Defaulted Interest, which Shall be fixed
         in the following manner. The Company shall notify the Trustee in
         writing of the amount of Defaulted Interest proposed to be paid on each
         such Registered Security and the date of the proposed payment, and
         shall deposit with the Trustee an amount of money equal to the
         aggregate amount proposed to be paid in respect of such Defaulted
         Interest or shall make arrangements satisfactory to the trustee for
         such deposit prior to the date of the proposed payment, Such money when
         deposited to be held in trust for the benefit of the persons entitled
         to such Defaulted Interest as in this clause (1) provided.


                                       35
<PAGE>   44
         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 of such Registered Securities at his or her
         address as it appears in the 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 such Registered Securities (or their respective Predecessor
         Securities) are registered at the close of business on such Special
         Record Date and shall no longer be payable pursuant to the following
         clause (2).

                  (2)(x) In the case of Registered Securities, the Company may
         make payment of such Defaulted Interest to the Persons in whose names
         such Registered Securities (or their respective Predecessor Securities)
         are registered at the close of business on a specified date in any
         other lawful manner not inconsistent with the requirements of any
         securities exchange on which such Registered Securities may be listed,
         and upon such notice as may be required by such exchange, if, after
         notice given by the Company to the Trustee of the proposed payment
         pursuant to this clause (2)(x), such manner of payment shall be deemed
         practicable by the Trustee; or (y) unless otherwise provided as
         contemplated by Section 3.1, in the case of Bearer Securities, the
         Company may make payment of Defaulted Interest on such Bearer
         Securities in any lawful manner not inconsistent with the requirements
         of any securities exchange on which such Bearer Securities may be
         listed, and upon such notice as may be required by such exchange, if,
         after notice given by the Company to the Trustee of the proposed
         payment pursuant to this clause (2)(y), such manner of payment shall be
         deemed practicable by the Trustee.

                  (c)    Subject to the foregoing provisions of this Section
and Section 3.5, each Security delivered under this Indenture upon registration
of transfer of or in exchange for or in lieu of any other Security shall carry
the rights to interest accrued and unpaid, and to accrue, which were carried by
such other Security.

                  (d)     Subject to the provisions of Section 14.2, in the
case of any Registered Security which is converted or exchanged after any
Regular Record Date and on or prior to the next succeeding Interest Payment Date
(other than any Security the principal of (or premium, if any, on) which shall
become due and payable, whether at a Stated Maturity or by declaration of
acceleration, call for redemption, or otherwise, prior to such Interest Payment
Date), interest whose Stated Maturity is on such Interest


                                       36
<PAGE>   45
Payment Date shall be payable on such Interest Payment Date notwithstanding such
conversion or exchange and such interest (whether or not punctually paid or duly
provided for) shall be paid to the Person in whose name that Registered Security
(or any one or more Predecessor Securities) is registered at the close of
business on such Regular Record Date. Except as otherwise expressly provided in
the immediately preceding sentence, in the case of any Security which is
converted or exchanged, interest whose Stated Maturity is after the date of
conversion or exchange of such Security shall not be payable.

                  Section 3.8. Persons Deemed Owners. Unless otherwise provided
as contemplated by Section 3.1, prior to due presentment of any Registered
Security 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 Registered
Security is registered as the owner of such Registered Security for the purpose
of receiving payment of principal of, premium, if any, and (subject to Section
3.7) interest on such Registered Security and for all other purposes whatsoever,
whether or not such Registered Security be overdue, and neither the Company, the
Trustee nor any agent of the Company or the Trustee shall be affected by notice
to the contrary.

                  Unless otherwise provided as contemplated by Section 3.1, the
Company, the Trustee and any agent of the Company or the Trustee may treat the
bearer of any Bearer Security and the bearer of any interest coupon as the
absolute owner of such Bearer Security or interest coupon for the purpose of
receiving payment thereof or on account thereof and for all other purposes
whatsoever, whether or not such Bearer Security or interest coupon 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.

                  None of the Company, the Trustee or any agent of the Company
or the Trustee shall have any responsibility or liability for any aspect of the
records relating to or payments made on account of beneficial ownership
interests of a Security in global form, or for maintaining, supervising or
reviewing any records relating to such beneficial ownership interests. No holder
of any beneficial interest in any Security in global form, held on its behalf by
or through a Depositary, shall have any rights under this Indenture with respect
to such Security in global form, and such Depositary may be treated by the
Company, the Trustee and any agent of the Company or the Trustee as the owner of
such Security in global form for all purposes whatsoever. With respect to any
Security in global form, nothing herein shall prevent the Company or the
Trustee, or any agent of the Company or the Trustee, from giving effect to any
written certification, proxy or other authorization furnished by any Depositary
(or its nominee), as a Holder, with respect to such Security in global form or
impair, as between such Depositary and owners of beneficial interests in such
Security in global form, the operation of customary practices


                                       37
<PAGE>   46
governing the exercise of the rights of such Depositary (or its nominee) as
Holder of such Security in global form.

                  Section 3.9. Cancellation. All Securities and interest
coupons appertaining thereto, if any, surrendered for payment, redemption,
conversion, registration of transfer or exchange or for credit against any
sinking fund payment 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 Securities, together
with interest coupons appertaining thereto, if any, previously authenticated and
delivered hereunder which the Company may have acquired in any manner
whatsoever, and may deliver to the Trustee (or to any other Person for delivery
to the Trustee) for cancellation any Securities, together with interest coupons
appertaining thereto, if any, previously authenticated hereunder which the
Company has not issued and sold, and all Securities and interest coupons so
delivered shall be promptly cancelled by the Trustee. No Securities shall be
authenticated in lieu of or in exchange for any Securities cancelled as provided
in this Section 3.9, except as expressly permitted by this Indenture. All
cancelled Securities and interest coupons held by the Trustee shall be disposed
of in accordance with its customary procedures, and the Trustee shall thereafter
deliver to the Company a certificate with respect to such disposition.

                  Section 3.10. Computation of Interest. Except as otherwise
specified as contemplated by Section 3.1, interest on the Securities of each
series shall be computed on the basis of a 360-day year of twelve 30-day months.

                  Section 3.11. CUSIP Numbers. The Company in issuing the
Securities may use "CUSIP" numbers (if then generally in use and in addition to
the other identification numbers printed on the Securities), and, in such case,
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 Securities
or as contained in any notice of a redemption and that reliance may be placed
only on the other identification numbers printed on the Securities, and any such
redemption shall not be affected by any defect in or omission of such numbers.

                  Section 3.12. Currency and Manner of Payment in Respect of
Securities. Unless otherwise specified with respect to any Securities pursuant
to Section 3.1, payment of the principal of, premium, if any, and interest, if
any, on any Security of such series will be made in the currency or currencies
or currency unit or units in which such Security is payable. The provisions of
this Section 3.12 may be modified or superseded pursuant to Section 3.1 with
respect to any Securities.

exchange Securities, (v) rights, obligations, duties and immunities of the
Trustee hereunder, (vi) any rights of the Holders of Securities of such series

                  Section 4.2. Application of Trust Funds. Subject to the
provisions of the last paragraph of Section 9.3, all money deposited with the
Trustee pursuant to Section 4.1 shall be held in trust and applied by it, in
accordance with the provisions of the Securities, the interest coupons
appertaining thereto, if any, and this Indenture, to the payment, either
directly or through any Paying Agent (including the Company acting as its own
Paying Agent) as the Trustee may determine, to the Persons entitled thereto, of
the principal, premium, if any and any interest for whose payment such money has
been


                                       40

deposited with or received by the Trustee, but such money need not be
segregated from other funds except as otherwise provided herein and except to
the extent required by law.

                  Section 4.3. Applicability of Defeasance Provisions; Company's
Option to Effect Defeasance or Covenant Defeasance. Except as otherwise
specified as contemplated by Section 3.1 for the Securities of any series, the
provisions of Sections 4.3 through 4.9 inclusive, with such modifications
thereto as may be specified pursuant to Section 3.1 with respect to any series
of Securities, shall be applicable to the Securities and any interest coupons
appertaining thereto.

                  Section 4.4. Defeasance and Discharge. On and after the date
on which the conditions set forth in Section 4.6 are satisfied with respect to
the Securities of or within any series, the Company shall be deemed to have paid
and been discharged from its obligations with respect to such Securities and any
interest coupons appertaining thereto (hereinafter "defeasance"). For this
purpose, such defeasance means that the Company shall be deemed to have paid and
discharged the entire indebtedness represented by such Securities and any
interest coupons appertaining thereto which shall thereafter be deemed to be
"Outstanding" only for the purposes of Section 4.7 and the other Sections of
this Indenture referred to in clause (ii) of this Section, and to have satisfied
all its other obligations under such Securities and any interest coupons
appertaining thereto and this Indenture insofar as such Securities and any
interest coupons appertaining thereto are concerned (and the Trustee, upon
payment of all amounts due it under Section 6.7, at the expense of the Company,
shall on a Company Order execute proper instruments acknowledging the same),
except the following which shall survive until otherwise terminated or
discharged hereunder: (i) the rights of Holders of such Securities and any
interest coupons appertaining thereto to receive, solely from the trust funds
described in Section 4.6(a) and as more fully set forth in such Section,
payments in respect of the principal of, premium, if any, and interest, if any,
on such Securities or any interest coupons appertaining thereto when such
payments are due; (ii) the Company's obligations with respect to such Securities
under Sections 3.5, 3.6, 9.2 and 9.3 and with respect to the payment of
additional amounts, if any, payable with respect to such Securities as specified
pursuant to Section 3.1(b)(16); (iii) the Company's obligations with respect to
a conversion or exchange of such Securities; (iv) the rights, powers, trusts,
duties and immunities of the Trustee hereunder and (v) this Article 4. Subject
to compliance with this Article 4, the Company may defease the Securities of any
series and any interest coupons appertaining thereto under this Section 4.4
notwithstanding a prior covenant defeasance (as defined herein) under Section
4.5 with respect to such Securities and any interest coupons appertaining
thereto. Following a defeasance, payment of such Securities may not be
accelerated because of an Event of Default.

                  Section 4.5. Covenant Defeasance. On and after the date on
which the conditions set forth in Section 4.6 (other than Section 4.6(c)) are
satisfied with respect to


                                       41
<PAGE>   50
the Securities of or within any series, (i) the Company shall be released from
its obligations under Sections 7.1 and 9.4 and, if specified pursuant to Section
3.1, its obligations under any other covenant, with respect to such Securities
and any interest coupons appertaining thereto and (ii) the occurrence of any
event specified in Sections 5.1(3) or 5.1(7) (with respect to any of the
obligations described in clause (i) above) or 5.1(4) shall be deemed not to be
or result in a Default or Event of Default (hereinafter, "covenant defeasance"),
and such Securities and any interest coupons appertaining thereto shall
thereafter be deemed to be not "Outstanding" for the purposes of any request,
demand, authorization, direction, notice, waiver, consent or declaration or Act
of Holders (and the consequences of any thereof) in connection with Section 7.1
or 9.4, such other covenant specified pursuant to Section 3.1, or Section
5.1(4), but shall continue to be deemed "Outstanding" for all other purposes
hereunder. For this purpose, such covenant defeasance means that, with respect
to such Securities and any interest coupons appertaining thereto, the Company
may omit to comply with and shall have no liability in respect of any term,
condition or limitation set forth in any such Section or such other covenant,
whether directly or indirectly, by reason of any reference elsewhere herein to
any such Section or such other covenant or by reason of reference in any such
Section or such other covenant to any other provision herein or in any other
document and such omission to comply shall not constitute a Default or an Event
of Default under Section 5.1(3), 5.1(4) or 5.1(7) or otherwise, as the case may
be, but, except as specified above, the remainder of this Indenture and such
Securities and any interest coupons appertaining thereto shall be unaffected
thereby.

                  Section 4.6. Conditions to Defeasance or Covenant Defeasance.
The following shall be the conditions to application of Section 4.4 or Section
4.5 to any Securities of or within a series and any interest coupons
appertaining thereto:

                  (a) The Company shall have deposited or caused to be deposited
irrevocably with the Trustee (or another trustee satisfying the requirements of
Section 6.9 who shall agree to comply with, and shall be entitled to the
benefits of, the provisions of Sections 4.3 through 4.9 inclusive and the last
paragraph of Section 9.3 applicable to the Trustee, for purposes of such
Sections also a "Trustee") as trust funds in trust for the purpose of making the
payments referred to in clauses (x) and (y) of this Section 4.6(a), specifically
pledged as security for, and dedicated solely to, the benefit of the Holders of
such Securities and any interest coupons appertaining thereto, with written
instructions to the Trustee as to the application thereof, (A) money in an
amount (in such currency, currencies or currency unit or units in which such
Securities and any interest coupons appertaining thereto are then specified as
payable at Maturity), or (B) if Securities of such series are not subject to
repayment at the option of Holders, Government Obligations which through the
payment of interest and principal in respect thereof in accordance with their
terms will provide, not later than one day before the due date of any payment
referred to in clause (x) or (y) of this Section 4.6(a), money in an amount or
(C) a


                                       42
<PAGE>   51
combination thereof in an amount, sufficient, in the opinion of a nationally
recognized firm of independent certified public accountants or a nationally
recognized investment banking firm expressed in a written certification thereof
delivered to the Trustee, to pay and discharge, and which shall be applied by
the Trustee to pay and discharge, (x) the principal of, premium, if any, and
interest, if any, on such Securities and any interest coupons appertaining
thereto on the Maturity of such principal or installment of principal or
interest and (y) any mandatory sinking fund payments applicable to such
Securities on the day on which such payments are due and payable in accordance
with the terms of this Indenture and such Securities and any interest coupons
appertaining thereto. Before such a deposit the Company may make arrangements
satisfactory to the Trustee for the redemption of Securities at a future date or
dates in accordance with Article 11 which shall be given effect in applying the
foregoing.

                  (b) No Default or Event of Default with respect to the
Securities of that series shall have occurred or be continuing on the date of
such a deposit or shall occur as a result of such a deposit or, insofar as
Sections 5.1(5) and (6) are concerned, shall occur at any time during the period
ending on the 91st day after the date of such deposit (it being understood that
this condition shall not be deemed satisfied until the expiration of such
period).

                  (c) In the case of an election under Section 4.4, the Company
shall have delivered to the Trustee an Officers' Certificate and an Opinion of
Counsel to the effect that (i) the Company has received from, or there has been
published by, the Internal Revenue Service a ruling, or (ii) since the date of
execution of this Indenture, there has been a change in the applicable U.S.
Federal income tax law, in either case to the effect that, and based thereon
such opinion shall confirm that, the Holders of such Securities and any interest
coupons appertaining thereto will not recognize income, gain or loss for U.S.
Federal income tax purposes as a result of such defeasance and will be subject
to U.S. Federal income tax on the same amount and in the same manner and at the
same times, as would have been the case if such deposit, defeasance and
discharge had not occurred.

                  (d) In the case of an election under Section 4.5, the Company
shall have delivered to the Trustee an Officers' Certificate and an Opinion of
Counsel to the effect that the Holders of such Securities and any interest
coupons appertaining thereto will not recognize income, gain or loss for U.S.
Federal income tax purposes as a result of such covenant defeasance and will be
subject to U.S. Federal income tax on the same amount and in the same manner and
at the same times, as would have been the case if such deposit and covenant
defeasance had not occurred.

                  (e) The Company shall have delivered to the Trustee an
Officers' Certificate and an Opinion of Counsel, each stating that all
conditions precedent to the


                                       43
<PAGE>   52
defeasance under Section 4.4 or the covenant defeasance under Section 4.5 (as
the case may be) have been complied with.

                  (f) Such defeasance or covenant defeasance shall be effected
in compliance with any additional or substitute terms, conditions or limitations
which may be imposed on the Company in connection therewith as contemplated by
Section 3.1.

                  Section 4.7. Deposited Money and Government Obligations to Be
Held in Trust. Subject to the provisions of the last paragraph of Section 9.3,
all money and Government Obligations (or other property as may be provided
pursuant to Section 3.1) (including the proceeds thereof) deposited with the
Trustee pursuant to Section 4.6 in respect of any Securities of any series and
any interest coupons appertaining thereto shall be held in trust and applied by
the Trustee, in accordance with the provisions of such Securities and any
interest coupons appertaining thereto and this Indenture, to the payment, either
directly or through any Paying Agent (including the Company acting as its own
Paying Agent) as the Trustee may determine, to the Holders of such Securities
and any interest coupons appertaining thereto of all sums due and to become due
thereon in respect of principal, premium, if any, and interest, if any, but such
money need not be segregated from other funds except as provided herein and
except to the extent required by law.

                  Section 4.8. Repayment to Company. The Trustee (and any
Paying Agent) shall promptly pay to the Company upon Company Request any excess
money or securities held by them at any time.

                  The provisions of the last paragraph of Section 9.3 shall
apply to any money or securities held by the Trustee or any Paying Agent under
this Article 4 that remain unclaimed for two years after the Maturity of any
series of Securities for which money or securities have been deposited pursuant
to Section 4.6(a).

                  Section 4.9. Indemnity for Government Obligations. The
Company shall pay, and shall indemnify the Trustee against, any tax, fee or
other charge imposed on or assessed against Government Obligations deposited
pursuant to this Article or the principal and interest and any other amount
received on such Government Obligations.

                  Section 4.10. Reinstatement. If the Trustee (or Paying Agent)
is unable to apply any money or Government Obligations in accordance with
Section 4.6 by reason of any order or judgment of any court or governmental
authority enjoining, restraining or otherwise prohibiting such application, then
the Company's obligations under this Indenture and the Securities shall be
revived and reinstated, with present and prospective effect, as though no
deposit had occurred pursuant to Section 4.6, until such time as the Trustee (or
Paying Agent) is permitted to apply all such money or Government


                                       44
<PAGE>   53
Obligations in accordance with Section 4.6; provided, however, that if the
Company makes any payment to the Trustee (or Paying Agent) of principal,
premium, if any, or interest on any Security following the reinstatement of its
obligations, the Trustee (or Paying Agent) shall promptly pay any such amount to
the Holders of the Securities and the Company shall be subrogated to the rights
of the Holders of such Securities to receive such payment from the money and
Government Obligations held by the Trustee (or Paying Agent).

                                    ARTICLE 5

                              DEFAULTS AND REMEDIES

                  Section 5.1. Events of Default. An "Event of Default" occurs
with respect to the Securities of any series if (whatever the reason for such
Event of Default and whether it shall be voluntary or involuntary or be effected
by operation of law or pursuant to any judgment, decree or order of any court or
any order, rule or regulation of any administrative or governmental body):

                  (1) the Company defaults in the payment of interest on any
         Security of that series or any interest coupon appertaining thereto or
         any additional amount payable with respect to any Security of that
         series as specified pursuant to Section 3.1(b)(16) when the same
         becomes due and payable and such default continues for a period of 30
         days;

                  (2) the Company defaults in the payment of any installment of
         the principal of or any premium on any Security of that series when the
         same becomes due and payable at its Maturity;

                  (3) the Company fails to comply with any of its agreements or
         covenants in, or any of the provisions of, this Indenture with respect
         to any Security of that series (other than an agreement, covenant or
         provision for which non-compliance is elsewhere in this Section
         specifically dealt with), and such non-compliance continues for a
         period of 90 days after there has been given, by registered or
         certified mail, return receipt requested, to the Company by the Trustee
         or to the Company and the Trustee by the Holders of at least 25% in
         aggregate principal amount of the Outstanding Securities of the series,
         a written notice specifying such default or breach and requiring it to
         be remedied and stating that such notice is a "Notice of Default"
         hereunder;

                  (4) the Company defaults under any mortgage, indenture or
         instrument under which there may be issued, or by which there may be
         secured or evidenced, any Debt (including this Indenture) having an
         aggregate principal amount outstanding of at least $25,000,000, whether
         such Debt now exists or shall


                                       45
<PAGE>   54
         hereafter be created, and, as a result of such default, such Debt shall
         become due and payable, whether by acceleration or otherwise, and such
         acceleration shall not be rescinded, annulled or cured within a period
         of 30 days after there has been given, by registered or certified mail,
         return receipt requested, to the Company by the Trustee or to the
         Company and the Trustee by the Holders of at least 25% in aggregate
         principal amount of the Outstanding Securities of that series a written
         notice specifying such default and requiring it to be remedied and
         stating that such notice is a "Notice of Default" hereunder (it being
         understood however, that the Trustee shall not be deemed to have
         knowledge of such default under such agreement or instrument unless a
         Responsible Officer of the Trustee shall have received written notice
         thereof from the Company, from any Holder, from the holder of any such
         Debt or from the trustee under any such agreement or other instrument);
         provided, however, that if such default under such mortgage, indenture
         or instrument is remedied or cured by the Company or waived by the
         holders of such Debt, then the Event of Default hereunder by reason
         thereof shall be deemed likewise to have been thereupon remedied, cured
         or waived without further action upon the part of either the Trustee or
         any of such Holders;

                  (5) the Company pursuant to or within the meaning of any
         Bankruptcy Law (A) commences a voluntary case, (B) consents to the
         entry of an order for relief against it in an involuntary case, (C)
         consents to the appointment of a Custodian of it or for all or
         substantially all of its property, (D) makes a general assignment for
         the benefit of its creditors or (E) admits in writing its inability
         generally to pay its debts as they become due;

                  (6) a court of competent jurisdiction enters an order or
         decree under any Bankruptcy Law that (A) is for relief against the
         Company in an involuntary case, (B) appoints a Custodian of the Company
         or for all or substantially all of its property, or (C) orders the
         liquidation of the Company, and such order or decree remains unstayed
         and in effect for 90 days; or

                  (7) there occurs any other Event of Default provided as
         contemplated by Section 3.1 with respect to Securities of that series.

                  The term "Bankruptcy Law" means Title 11, United States
Bankruptcy Code of 1978, as amended, or any similar United States federal or
state law relating to bankruptcy, insolvency, receivership, reorganization or
relief of debtors or any amendment to, successor to or change in any such law.
The term "Custodian" means any receiver, trustee, assignee, liquidator,
custodian, sequestrator or similar official under any Bankruptcy Law.


                                       46

<PAGE>   55
                  Section 5.2. Acceleration; Rescission and Annulment. If an
Event of Default with respect to the Securities of any series at the time
Outstanding (other than an Event of Default specified in clause (5) or (6) of
Section 5.1) occurs and is continuing, the Trustee or the Holders of at least
25% in aggregate principal amount of all of the Outstanding Securities of that
series, by written notice received by the Company (and, if given by the Holders,
received by the Trustee), may declare the principal (or, if the Securities of
that series are Original Issue Discount Securities or Indexed Securities, such
portion of the principal amount as may be specified in the terms of that series)
of and accrued interest, if any, on all the Securities of that series to be due
and payable and upon any such declaration such principal (or, in the case of
Original Issue Discount Securities or Indexed Securities, such specified amount)
and interest, if any, shall be immediately due and payable. If an Event of
Default specified in clause (5) or (6) of Section 5.1 with respect to the
Securities of any series at the time Outstanding occurs and is continuing, then
the principal (or, if the Securities of that series are Original Issue Discount
Securities or Indexed Securities, such portion of the principal amount as may be
specified in the terms of that series) of and accrued interest, if any, on all
the Securities of that series shall ipso facto be immediately due and payable
without any declaration or act on the part of the Trustee or any Holder of such
Securities.

                  At any time after such a declaration of acceleration with
respect to Securities of any series has been made and before a judgment or
decree for payment of the money due has been obtained by the Trustee as
hereinafter in this Article provided, the Holders of a majority in aggregate
principal amount of the Outstanding Securities of that series, by written notice
to the Trustee, may rescind and annul such declaration and its consequences if
all existing Defaults and Events of Default with respect to Securities of that
series, other than the non-payment of the principal of Securities of that series
which have become due solely by such declaration of acceleration, have been
cured or waived as provided in Section 5.7. No such rescission shall affect any
subsequent default or impair any right consequent thereon.

                  Section 5.3. Collection of Indebtedness and Suits for
Enforcement by Trustee. The Company covenants that if

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

                  (2) default is made in the payment of the principal of (or
         premium, if any, on) any Security at the Maturity thereof, the Company
         will, upon demand of the Trustee, pay to it, for the benefit of the
         Holders of such Securities or interest coupons, if any, the whole
         amount then due and payable on such Securities for principal, premium,
         if any, and interest and, to the extent that payment of such

                                       47
<PAGE>   56
         interest shall be legally enforceable, interest on any overdue
         principal, premium, if any, and on any overdue interest, at the rate or
         rates prescribed therefor in such Securities or interest coupons, if
         any, and, in addition thereto, such further amount as shall be
         sufficient to cover the costs and expenses of collection, including all
         amounts due the Trustee, its agents and counsel under Section 6.7.

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

                  If an Event of Default with respect to Securities of any
series occurs and is continuing, the Trustee may in its discretion proceed to
protect and enforce its rights and the rights of the Holders of Securities of
such series by such appropriate judicial proceedings as the Trustee shall deem
most effectual to protect and enforce any such rights, whether for the specific
enforcement of any covenant or agreement in this Indenture or in aid of the
exercise of any power granted herein, or to secure any other proper remedy,
subject, however, to Section 5.8.

                  Section 5.4. Trustee May File Proofs of Claim. In case of any
judicial proceeding relative to the Company (or any other obligor upon the
Securities), 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 the Trustee allowed in any such proceeding. In particular, the
Trustee shall be 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 6.7.

                  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 of a Security or interest coupon any plan of reorganization, arrangement,
adjustment or composition affecting the Securities or the rights of any Holder
of a Security or interest coupon thereof or to authorize the Trustee to vote in
respect of the claim of any Holder of a Security or interest coupon in any such
proceeding; provided, however, that the Trustee may, on behalf of the

                                       48
<PAGE>   57
Holders, vote for the election of a trustee in bankruptcy or similar official
and be a member of a creditors' or other similar committee.

                  Section 5.5. Trustee May Enforce Claims Without Possession of
Securities. All rights of action and claims under this Indenture or the
Securities may be prosecuted and enforced by the Trustee without the possession
of any of the Securities or the production thereof in any proceeding relating
thereto.

                  Section 5.6 Delay or Omission Not Waiver. No delay or omission
by the Trustee or any Holder of any Securities to exercise any right or remedy
accruing upon an Event of Default shall impair any such right or remedy or
constitute a waiver of or acquiescence in any such Event of Default.

                  Section 5.7. Waiver of Past Defaults. The Holders of not less
than a majority in aggregate principal amount of Outstanding Securities of any
series by written notice to the Trustee may waive on behalf of the Holders of
all Securities of such series and any interest coupons appertaining thereto a
past Default or Event of Default with respect to that series and its
consequences except (i) a Default or Event of Default in the payment of the
principal of, premium, if any, or interest on any Security of such series or any
interest coupon appertaining thereto or (ii) in respect of a covenant or
provision hereof which pursuant to Article 8 cannot be amended or modified
without the consent of the Holder of each Outstanding Security of such series
affected. Upon any such waiver, such Default shall cease to exist, and any Event
of Default arising therefrom shall be deemed to have been cured, for every
purpose of this Indenture but no such waiver shall extend to any subsequent or
other default or impair any right consequent thereon.

                  Section 5.8. Control by Majority. The Holders of not less than
a majority in aggregate principal amount of the Outstanding Securities of each
series affected (with each such series voting as a class) shall have the right
to direct the time, method and place of conducting any proceeding for any remedy
available to the Trustee or exercising any trust or power conferred on it with
respect to Securities of that series; provided, however, that (i) the Trustee
may refuse to follow any direction that conflicts with any governmental rule or
law or this Indenture, (ii) the Trustee may refuse to follow any direction that
is unduly prejudicial to the rights of the Holders of Securities of such series
not consenting, or that would in the good faith judgment of the Trustee have a
substantial likelihood of involving the Trustee in personal liability without
adequate indemnity having been offered therefor and (iii) subject to Section
6.1, the Trustee may take any other action deemed proper by the Trustee which is
not inconsistent with such direction.

                  Section 5.9. Limitation on Suits by Holders. No Holder of any

                  (1) the Holder has previously given written notice to the
         Trustee of a continuing Event of Default with respect to the Securities
         of that series;

                  (2) the Holders of at least 25% in aggregate principal amount
         of the Outstanding Securities of that series have made a written
         request to the Trustee to institute proceedings in respect of such
         Event of Default in its own name as Trustee hereunder;

                  (3) such Holder or Holders have offered to the Trustee
         indemnity satisfactory to the Trustee against any loss, liability or
         expense to be, or which may be, incurred by the Trustee in pursuing the
         remedy;

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

                  (5) during such 60-day period, the Holders of a majority in
         aggregate principal amount of the Outstanding Securities of that series
         have not given to the Trustee a direction inconsistent with such
         written request.

                  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 of such Holders, or to
obtain or to seek to obtain priority or preference over any other of such
Holders or to enforce any right under this Indenture, except in the manner
herein provided and for the equal and ratable benefit of all of such Holders.

an interest coupon to receive payment of interest due as provided in such
interest coupon, or to bring suit for the enforcement of any such payment on or
after such respective dates, and the right, if any, to convert or exchange such
Security in accordance with Article 14, shall not be impaired or affected
without the consent of such Holder.

collects any money pursuant to this Article, it shall pay out the money in the
following order, at the date or dates fixed by the Trustee and, in case of the

<PAGE>   59
account of principal, premium, if any, or interest, upon presentation of the
Securities and interest coupons, if any, and the notation thereon of the payment
if only partially paid and upon surrender thereof if fully paid:

                  First: to the Trustee for amounts due under Section 6.7;

                  Second: to Holders of Securities and interest coupons in
         respect of which or for the benefit of which such money has been
         collected for amounts due and unpaid on such Securities for principal

determined by the Trustee by converting the principal amount Outstanding of such
series of Securities and matured but unpaid interest on such series of
Securities in the currency in which such series of Securities is denominated
into Dollars at the Market Exchange Rate as of the date of declaration of
acceleration of Maturity of the Securities.

                  The Trustee may fix a record date and payment date for any
payment to Holders pursuant to this Section 5.11. At least 15 days before such
record date, the Trustee shall mail to each Holder and the Company a notice that
states the record date, the payment date and the amount to be paid.

                  Section 5.12. 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 as though no such
proceeding had been instituted.

otherwise provided with respect to the replacement or payment of mutilated,
destroyed, lost or stolen Securities in the last paragraph of Section 3.6, no

                                       51
<PAGE>   60
hereafter existing at law or in equity or otherwise. The assertion or employment
of any right or remedy hereunder, or otherwise, shall not prevent the concurrent
assertion or employment of any other appropriate right or remedy.

                  Section 5.14. Undertaking for Costs. In any suit for the
enforcement of any right or remedy under this Indenture, or in any suit against
the Trustee for any action taken, 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, however,
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.

                  Section 5.15. Waiver of Stay, Extension or Usury 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 or any usury or other law
wherever enacted, now or at any time hereafter in force, which would prohibit or
forgive the Company from paying all or any portion of the principal, of, and
premium, if any, or interest on the Securities contemplated herein or in the
Securities or which may affect the covenants or the performance of this
Indenture; and the Company (to the extent that it may lawfully do so) hereby
expressly waives all benefit or advantage of any such law, and covenants that it
will not hinder, delay or impede the execution of any power herein granted to
the Trustee, but will suffer and permit the execution of every such power as
though no such law had been enacted.

                  Section 6.1. Certain Duties and Responsibilities. The duties
and responsibilities of the Trustee shall be as provided by the Trust Indenture
Act. Notwithstanding the foregoing, no provision of this Indenture shall require
the Trustee to expend or risk its own funds or otherwise incur any financial
liability in the performance of any of its duties hereunder, or in the exercise
of any of its rights or powers, if it shall have reasonable grounds for
believing that repayment of such funds or adequate indemnity against such risk
or liability is not reasonably assured to it. Whether or not therein expressly
so provided, every provision of this Indenture relating to the conduct or
affecting the liability of or affording protection to the Trustee shall be
subject to the provisions of this Section.

                  Section 6.2. Notice of Defaults. If a default occurs hereunder
with respect to Securities of any series, the Trustee shall give the Holders of
Securities of such series notice of such default as and to the extent provided
by the Trust Indenture Act;

                                       52
<PAGE>   61
provided, however, that in the case of any default of the character specified in
Section 5.1(3) with respect to Securities of such series, no such notice to
Holders shall be given until at least 30 days after the occurrence thereof. For
the purpose of this Section, the term "default" means any event which is, or
after notice or lapse of time or both would become, an Event of Default with
respect to Securities of such series.

                  Section 6.3. Certain Rights of Trustee. Subject to the
provisions of Section 6.1:

                  (1) the Trustee may rely and shall be protected in acting or
         refraining from acting upon any resolution, certificate, statement,
         instrument, opinion, report, notice, request, direction, consent,
         order, bond, debenture, note, other evidence of indebtedness or other
         paper or document believed by it to be genuine and to have been signed
         or presented by the proper party or parties;

                  (2) any request or direction of the Company mentioned herein
         shall be sufficiently evidenced by a Company Request or Company Order,
         and any resolution of the Board of Directors shall be sufficiently
         evidenced by a Board Resolution;

                  (3) whenever in the administration of this Indenture the
         Trustee shall deem it desirable that a matter be proved or established
         prior to taking, suffering or omitting any action hereunder, the
         Trustee (unless other evidence be herein specifically prescribed) may,
         in the absence of bad faith on its part, rely upon an Officers'
         Certificate;

                  (4) the Trustee may consult with counsel and the written
         advice of such counsel or any Opinion of Counsel shall be full and
         complete authorization and protection in respect of any action taken,
         suffered or omitted by it hereunder in good faith and in reliance
         thereon;

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

                  (6) the Trustee shall not be bound to make any investigation
         into the facts or matters stated in any resolution, certificate,
         statement, instrument, opinion, report, notice, request, direction,
         consent, order, bond, debenture, note, other evidence of indebtedness
         or other paper or document, but the Trustee, in its discretion, may
         make such further inquiry or investigation into such facts or

                                       53
<PAGE>   62
         matters as it may see fit, and, if the Trustee shall determine to make
         such further inquiry or investigation, it shall be entitled to examine
         the books, records and premises of the Company, personally or by agent
         or attorney;

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

                  (8) except with respect to Section 9.1, the Trustee shall have
         no duty to inquire as to the performance by the Company of the
         covenants set forth in Article 9 beyond its good faith review of any
         certificates or other notices received by it from the Company.

                  Section 6.4. Not Responsible for Recitals or Issuance of
Securities. The recitals contained herein and in the Securities, except the
Trustee's certificates of authentication, shall be taken as the statements of
the Company and neither the Trustee nor any Authenticating Agent assumes any
responsibility for their correctness. The Trustee makes no representations as to
the validity or sufficiency of this Indenture or of the Securities. Neither the
Trustee nor any Authenticating Agent shall be accountable for the use or
application by the Company of Securities or the proceeds thereof.

                  Section 6.5. May Hold Securities. The Trustee, any
Authenticating Agent, any Paying Agent, any Security Registrar or any other
agent of the Company or the Trustee, in its individual or any other capacity,
may become the owner or pledgee of Securities and, subject to Sections 6.8 and
6.13, may otherwise deal with the Company and any other obligor upon the
Securities with the same rights it would have if it were not Trustee,
Authenticating Agent, Paying Agent, Security Registrar or such other agent.

   
                  Section 6.6. Money Held in Trust. Money held by the Trustee in
trust hereunder need not be segregated from other funds except to the extent
required by law. The Trustee shall be under no liability for interest on any
money received by it hereunder except as otherwise agreed with the Company.
    

                  Section 6.7. Compensation and Reimbursement. The Company
agrees

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

                                       54
<PAGE>   63
                  (2) except as otherwise expressly provided herein, to
         reimburse the Trustee upon its request for all reasonable expenses,
         disbursements and advances incurred or made by the Trustee in
         accordance with any provision of this Indenture (including the
         reasonable compensation and the expenses and disbursements of its
         agents and counsel), except any such expense, disbursement or advance
         as may be attributable to its negligence or bad faith; and

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

shall acquire a conflicting interest within the meaning of the Trust Indenture
Act, the Trustee shall either eliminate such interest or resign, to the extent
and in the manner provided by, and subject to the provisions of, the Trust
Indenture Act and this Indenture. To the extent permitted by such Act, the
Trustee shall not be deemed to have a conflicting interest by virtue of being a
trustee under this Indenture with respect to Securities of more than one series

Company and the Trustee relating to the Company's 11.30% Senior Discount Notes

shall at all times be a Trustee hereunder which shall be a Person that is
eligible pursuant to the Trust Indenture Act to act as such, has a combined
capital and surplus of at least $50,000,000 and has its Corporate Trust Office
located in the Borough of Manhattan, The City of New York. If such Person
publishes reports of condition at least annually, pursuant to law or to the
requirements of its supervising or examining authority, then for the purposes of
this Section, the combined capital and surplus of such Person shall be deemed to
be its combined capital and surplus as set forth in its most recent report of
condition so published. If at any time the Trustee shall cease to be eligible in
accordance with the

                                       55
<PAGE>   64
provisions of this Section, it shall resign immediately in the manner and with
the effect hereinafter specified in this Article.

                  Section 6.10. Resignation and Removal; Appointment of
Successor. No resignation or removal of the Trustee and no appointment of a
successor Trustee pursuant to this Article shall become effective until the
acceptance of appointment by the successor Trustee in accordance with the
applicable requirements of Section 6.11.

                  The Trustee may resign at any time with respect to the
Securities of one or more series by giving written notice thereof to the
Company. If the instrument of acceptance by a successor Trustee required by
Section 6.11 shall not have been delivered to the Trustee within 30 days after
the giving of such notice of resignation, the resigning Trustee may petition any
court of competent jurisdiction for the appointment of a successor Trustee with
respect to the Securities of such series.

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

                  If at any time:

                  (1) the Trustee shall fail to comply with Section 6.8 after
         written request therefor by the Company or by any Holder who has been a
         bona fide Holder of a Security for at least six months, or

                  (2) the Trustee shall cease to be eligible under Section 6.9
         and shall fail to resign after written request therefor by the Company
         or by any such Holder, or

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

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

                  If the Trustee shall resign, be removed or become incapable of
acting, or if a vacancy shall occur in the office of Trustee for any cause, with
respect to the Securities

                                       56
<PAGE>   65
of one or more series, the Company, by a Board Resolution, shall promptly
appoint a successor Trustee or Trustees with respect to the Securities of that
or those series (it being understood that any such successor Trustee may be
appointed with respect to the Securities of one or more or all of such series
and that at any time there shall be only one Trustee with respect to the
Securities of any particular series) and shall comply with the applicable
requirements of Section 6.11. If, within one year after such resignation,
removal or incapability, or the occurrence of such vacancy, a successor Trustee
with respect to the Securities of any series shall be appointed by Act of the
Holders of a majority in principal amount of the Outstanding Securities of such
series delivered to the Company and the retiring Trustee, the successor Trustee
so appointed shall, forthwith upon its acceptance of such appointment in
accordance with the applicable requirements of Section 6.11, become the
successor Trustee with respect to the Securities of such series and to that
extent supersede the successor Trustee appointed by the Company. If no successor
Trustee with respect to the Securities of any series shall have been so
appointed by the Company or the Holders and accepted appointment in the manner
required by Section 6.11, any Holder who has been a bona fide Holder of a
Security of such series for at least six months may, on behalf of himself and
all others similarly situated, petition any court of competent jurisdiction for
the appointment of a successor Trustee with respect to the Securities of such
series. The Company shall give notice of each resignation and each removal of
the Trustee with respect to the Securities of any series and each appointment of
a successor Trustee with respect to the Securities of any series to all Holders
of Securities of such series in the manner provided in Section 1.6. Each notice
shall include the name of the successor Trustee with respect to the Securities
of such series and the address of its Corporate Trust Office.

                  Section 6.11. Acceptance of Appointment by Successor. In case
of the appointment hereunder of a successor Trustee with respect to all
Securities, every such successor Trustee so appointed shall execute, acknowledge
and deliver to the Company and to the retiring Trustee an instrument accepting
such appointment, and thereupon the resignation or removal of the retiring
Trustee shall become effective and such successor Trustee, without any further
act, deed or conveyance, shall become vested with all the rights, powers, trusts
and duties of the retiring Trustee; but, on the request of the Company or the
successor Trustee, such retiring Trustee shall, upon payment of its charges,
execute and deliver an instrument transferring to such successor Trustee all the
rights, powers and trusts of the retiring Trustee and shall duly assign,
transfer and deliver to such successor Trustee all property and money held by
such retiring Trustee hereunder.

                  In case of the appointment hereunder of a successor Trustee
with respect to the Securities of one or more (but not all) series, the Company,
the retiring Trustee and each successor Trustee with respect to the Securities
of one or more series shall execute and deliver an indenture supplemental hereto
wherein each successor Trustee shall accept

                                       57
<PAGE>   66
such appointment and which (1) shall contain such provisions as shall be
necessary or desirable to transfer and confirm to, and to vest in, each
successor Trustee all the rights, powers, trusts and duties of the retiring
Trustee with respect to the Securities of that or those series to which the
appointment of such successor Trustee relates, (2) if the retiring Trustee is
not retiring with respect to all Securities, shall contain such provisions as
shall be deemed necessary or desirable to confirm that all the rights, powers,
trusts and duties of the retiring Trustee with respect to the Securities of that
or those series as to which the retiring Trustee is not retiring shall continue
to be vested in the retiring Trustee, and (3) shall add to or change any of the
provisions of this Indenture as shall be necessary to provide for or facilitate
the administration of the trusts hereunder by more than one Trustee, it being
understood that nothing herein or in such supplemental indenture shall
constitute such Trustees co-trustees of the same trust and that each such
Trustee shall be trustee of a trust or trusts hereunder separate and apart from
any trust or trusts hereunder administered by any other such Trustee; and upon
the execution and delivery of such supplemental indenture the resignation or
removal of the retiring Trustee shall become effective to the extent provided
therein and each such successor Trustee, without any further act, deed or
conveyance, shall become vested with all the rights, powers, trusts and duties
of the retiring Trustee with respect to the Securities of that or those series
to which the appointment of such successor Trustee relates; but, on request of
the Company or any successor Trustee, such retiring Trustee shall duly assign,
transfer and deliver to such successor Trustee all property and money held by
such retiring Trustee hereunder with respect to the Securities of that or those
series to which the appointment of such successor Trustee relates.

                  Upon request of any such successor Trustee, the Company shall
execute any and all instruments for more fully and certainly vesting in and
confirming to such successor Trustee all such rights, powers and trusts referred
to in the first or second preceding paragraph, as the case may be.

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

                  Section 6.12. Merger, Conversion, Consolidation or Succession
to Business. Any corporation into which the Trustee may be merged or converted
or with which it may be consolidated, or any corporation resulting from any
merger, conversion or consolidation to which the Trustee shall be a party, or
any corporation succeeding to all or substantially all the corporate trust
business of the Trustee, shall be the successor of the Trustee hereunder,
provided such corporation shall be otherwise qualified and eligible under this
Article, without the execution or filing of any paper or any further act on the
part of any of the parties hereto. In case any Securities shall have been
authenticated, but not delivered, by the Trustee then in office, any successor
by merger, conversion or

                                       58
<PAGE>   67
consolidation to such authenticating Trustee may adopt such authentication and
deliver the Securities so authenticated with the same effect as if such
successor Trustee had itself authenticated such Securities.

                  Section 6.13. Preferential Collection of Claims Against
Company. If and when the Trustee shall be or become a creditor of the Company
(or any other obligor upon the Securities), the Trustee shall be subject to the
provisions of the Trust Indenture Act regarding the collection of claims against
the Company (or any such other obligor).

                  Section 6.14. Appointment of Authenticating Agent. The Trustee
may appoint an Authenticating Agent or Agents with respect to one or more series
of Securities which shall be authorized to act on behalf of the Trustee to
authenticate Securities of such series issued upon original issue and upon
exchange, registration of transfer or partial redemption thereof or pursuant to
Section 3.6, and Securities so authenticated shall be entitled to the benefits
of this Indenture and shall be valid and obligatory for all purposes as if
authenticated by the Trustee hereunder. Wherever reference is made in this
Indenture to the authentication and delivery of Securities by the Trustee or the
Trustee's certificate of authentication, such reference shall be deemed to
include authentication and delivery on behalf of the Trustee by an
Authenticating Agent and a certificate of authentication executed on behalf of
the Trustee by an Authenticating Agent. Each Authenticating Agent shall be
acceptable to the Company and shall at all times be a corporation organized and
doing business under the laws of the United States of America, any State thereof
or the District of Columbia, authorized under such laws to act as Authenticating
Agent, having a combined capital and surplus of not less than $50,000,000 and
subject to supervision or examination by Federal or State authority. If such
Authenticating Agent publishes reports of condition at least annually, pursuant
to law or to the requirements of said supervising or examining authority, then
for the purposes of this Section, the combined capital and surplus of such
Authenticating Agent shall be deemed to be its combined capital and surplus as
set forth in its most recent report of condition so published. If at any time an
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, such Authenticating Agent shall resign immediately
in the manner and with the effect specified in this Section.

                  Any corporation into which an Authenticating Agent may be
merged or converted or with which it may be consolidated, or any corporation
resulting from any merger, conversion or consolidation to which such
Authenticating Agent shall be a party, or any corporation succeeding to the
corporate agency or corporate trust business of an Authenticating Agent, shall
continue to be an Authenticating Agent, provided such corporation shall be
otherwise eligible under this Section, without the execution or filing of any
paper or any further act on the part of the Trustee or the Authenticating Agent.

                  An Authenticating Agent may resign at any time by giving
written notice thereof to the Trustee and to the Company. The Trustee may at any
time terminate the agency of an Authenticating Agent by giving written notice
thereof to such Authenticating Agent and to the Company. Upon receiving such a
notice of resignation or upon such a termination, or in case at any time such
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, the Trustee may appoint a successor Authenticating
Agent which shall be acceptable to the Company and shall give notice of such
appointment in the manner provided in Section 1.6 to all Holders of Securities
of the series with respect to which such Authenticating Agent will serve. Any
successor Authenticating Agent upon acceptance of its appointment hereunder
shall become vested with all the rights, powers and duties of its predecessor
hereunder, with like effect as if originally named as an Authenticating Agent.
No successor Authenticating Agent shall be appointed unless eligible under the
provisions of this Section.

                  The Trustee agrees to pay to each Authenticating Agent from
time to time reasonable compensation for its services under this Section, and
the Trustee shall be entitled to be reimbursed for such payments, subject to the
provisions of Section 6.7.

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

                  This is one of the Securities of the series designated therein
referred to in the within-mentioned Indenture.

                  Section 7.1. Consolidation, Merger or Sale of Assets
Permitted. The Company shall not consolidate with or merge into, or sell,
transfer, lease or otherwise dispose of its properties and assets as, or
substantially as, an entirety to, any Person unless:

                  (1) (A) the Company will be the surviving entity or (B) the
         Person formed by or surviving any such consolidation or merger (if
         other than the Company), or to which such sale, transfer, lease or
         other disposition shall have been made, is an entity organized and
         existing under the laws of the United States, any State thereof or the
         District of Columbia;

   
                  (2) the Person formed by or surviving any such consolidation
         or merger (if other than the Company), or to which such sale, transfer,
         lease or other disposition shall have been made, expressly assumes by
         supplemental indenture all the obligations of the Company under the
         Securities and this Indenture, and the Securities and this Indenture
         will remain in full force and effect as so supplemented;
    

   
                  (3) immediately after giving effect to such consolidation,
         merger, sale, transfer, lease or other disposition, no Default or Event
         of Default exists; and
    

   
                  (4) with respect to any series of Securities, the Company
satisfies such other conditions, if any, established with respect to such
series of Securities pursuant to and in accordance with Section 3.1.
    

                  The Company shall deliver to the Trustee prior to the proposed
consolidation, merger, sale, transfer, lease or other disposition an Officers'
Certificate to the foregoing effect and an Opinion of Counsel stating that the
proposed consolidation, merger, sale, transfer, lease or other disposition and
such supplemental indenture comply with this Indenture and that all conditions
precedent to the consummation of such transaction under this Section 7.1 have
been met.

                  Upon any consolidation of the Company with, or merger of the
Company into, any other Person or any sale, transfer, lease or other disposition
of properties and assets of the Company as, or substantially as, an entirety in
accordance with this Section 7.1, the successor Person formed by such
consolidation or into which the Company is merged or to which such sale,
transfer, lease or other disposition is made shall succeed to and be substituted
for, and may exercise every right and power of, the Company hereunder and under
the Securities and any interest coupons appertaining thereto with the same
effect as if such successor Person had been named hereunder and thereunder and
thereafter, except in the case of a lease, the predecessor Person shall be
relieved of all obligations and covenants under this Indenture and the
Securities.

                  Section 8.1. Supplemental Indentures Without Consent of
Holders. Without the consent of any Holders, the Company and the Trustee, at any
time and from time to time, may enter into indentures supplemental hereto, in
form reasonably satisfactory to the Trustee, for any of the following purposes:

                  (1) to evidence the succession of another Person to the
         Company and the assumption by any such successor of the covenants and
         obligations of the Company herein and in the Securities and any
         interest coupons appertaining thereto; or

                  (2) to add to the covenants of the Company for the benefit of
         the Holders of all or any series of Securities (and if such covenants
         are to be for the benefit of less than all series of securities,
         stating that such covenants are expressly being included solely for the
         benefit of such series) or to surrender any right or power herein
         conferred upon the Company; or

                  (3) to add any additional Events of Default with respect to
         all or any series of Securities; or

                  (4) to add to or change any of the provisions of this
         Indenture to such extent as shall be necessary to facilitate the
         issuance or administration of Bearer Securities (including, without
         limitation, to provide that Bearer Securities may be registrable as to
         principal only) or to facilitate the issuance or administration of
         Securities in global form; or

                  (5) to change or eliminate any of the provisions of this
         Indenture in respect of one or more series of Securities, provided that
         any such change or elimination shall become effective only when there
         is no Security Outstanding of any series created prior to the execution
         of such supplemental indenture which is entitled to the benefit of such
         provision; or

                  (6) to secure the Securities; or

                  (7) to establish the form or terms of Securities of any series
         as permitted by Sections 2.1 and 3.1; or

                  (8) to evidence and provide for the acceptance of appointment
         hereunder by a successor Trustee with respect to the Securities of one
         or more series and to add to or change any of the provisions of this
         Indenture as shall be necessary to

                                       62
<PAGE>   71
         provide for or facilitate the administration of the trusts hereunder by
         more than one Trustee, pursuant to the requirements of Section 6.11; or

                  (9) if allowed without penalty under applicable laws and
         regulations, to permit payment in the United States (including any of
         the States thereof and the District of Columbia), its territories, its
         possessions and other areas subject to its jurisdiction of principal,
         premium, if any, or interest, if any, on Bearer Securities or interest
         coupons, if any; or

                  (10) to correct or supplement any provision herein which may
         be inconsistent with any other provision herein or to make any other
         provisions with respect to matters or questions arising under this
         Indenture, provided such action shall not adversely affect in any
         material respect the interests of the Holders of Securities of any
         series; or

                  (11) to make provision not adverse to the Holders of
         Outstanding Securities of any series with respect to any conversion or
         exchange rights of Holders pursuant to the requirements of Article 14,
         including providing for the conversion or exchange of the Securities
         into any Equity Securities or property of the Company; or

                  (12) to cure any ambiguity, correct any mistake or comply with
         any mandatory provision of law; or

                  (13) to modify, eliminate or add to the provisions of this
         Indenture to such extent as shall be necessary to effect the
         qualification of this Indenture under the Trust Indenture Act or under
         any similar federal statute subsequently enacted, and to add to this
         Indenture such other provisions as may be expressly required under the
         Trust Indenture Act.

                  Section 8.2. Supplemental Indentures With Consent of Holders.
With the consent of the Holders of not less than a majority of the aggregate
principal amount of the Outstanding Securities of all series adversely affected
by such supplemental indenture (voting as one class), by Act of said Holders
delivered to the Company, the Company and the Trustee may enter into an
indenture or indentures supplemental hereto to add any provisions to or to
change in any manner or eliminate any provisions of this Indenture or of any
other indenture supplemental hereto or to modify in any manner the rights of the
Holders of such Securities; provided, however, that without the consent of the
Holder of each Outstanding Security affected thereby, an amendment under this
Section may not:

                  (1) change the Stated Maturity of the principal of, or
         premium, if any, on, or any installment of principal of or premium, if
         any, or interest on, any Security, or reduce the principal amount
         thereof or the rate of interest thereon or

                                       63
<PAGE>   72
         any premium payable upon the redemption thereof, or change the manner
         in which the amount of any principal thereof or premium, if any, or
         interest thereon is determined or reduce the amount of the principal of
         any Original Issue Discount Security or Indexed Security that would be
         due and payable upon a declaration of acceleration of the Maturity
         thereof pursuant to Section 5.2, or change the currency or currency
         unit in which any Securities or any premium or the 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);

                  (2) reduce the percentage in principal amount of the
         Outstanding Securities of any series, 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 reduce the
         requirements of Section 13.4 for quorum or voting;

                  (3) change any obligation of the Company to maintain an office
         or agency in the places and for the purposes specified in Section 9.2;

                  (4) make any change that adversely affects any right to
         convert or exchange any Security to which the provisions of Article 14
         are applicable or, except as provided in this Indenture, decrease the
         conversion or exchange rate or increase the conversion or exchange
         price of any such Security; or

                  (5) make any change in this Section 8.2 except to increase any
         percentage or to provide that certain other provisions of this
         Indenture cannot be modified or waived with the consent of the Holders
         of each Outstanding Security affected thereby.

                  A supplemental indenture which changes or eliminates any
covenant or other provision of this Indenture which has expressly been included
solely for the benefit of one or more particular series of Securities, or which
modifies the rights of the Holders of Securities of such series with respect to
such covenant or other provision, shall be deemed not to affect the rights under
this Indenture of the Holders of Securities of any other series.

                  It is not necessary under this Section 8.2 for the Holders to
consent to the particular form of any proposed supplemental indenture, but it is
sufficient if they consent to the substance thereof.

                  Section 8.3. Compliance with Trust Indenture Act. Every
amendment to this Indenture or the Securities of one or more series shall be set
forth in a supplemental indenture that complies with the Trust Indenture Act as
then in effect.

                  Section 8.4. Execution of Supplemental Indentures. In
executing, or accepting the additional trusts created by, any supplemental
indenture permitted by this Article or the modification thereby of the trusts
created by this Indenture, the Trustee shall be entitled to receive, and
(subject to Section 6.1) shall be fully protected in relying upon, an Officers'
Certificate and 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 8.5. 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 Securities
theretofore or thereafter authenticated and delivered hereunder and of any
interest coupon appertaining thereto shall be bound thereby.

                  Section 8.6. Reference in Securities to Supplemental
Indentures. Securities, including any interest coupons, of any series
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 Securities
including any interest coupons of any series so modified as to conform, in the
opinion of 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 Securities including any interest coupons of such
series.

                  Section 8.7. Notice of Supplemental Indentures. Promptly after
the execution by the Company and the Trustee of any supplemental indenture
pursuant to the provisions of Section 8.2, the Company shall give notice thereof
to the Holders of each Outstanding Security affected, in the manner provided for
in Section 1.6, setting forth in general terms the substance of such
supplemental indenture. Any failure of the Company to give such notice, or any
defect therein, shall not, however, in any way impair or affect the validity of
any such supplemental indenture.

                                    COVENANTS

                  Section 9.1. Payment of Principal, Premium, if any, and
Interest. The Company covenants and agrees for the benefit of the Holders of
each series of Securities that it will duly and punctually pay the principal of,
premium, if any, and interest, together with additional amounts, if any, on the
Securities of that series in accordance with the terms of the Securities of such
series, any interest coupons appertaining thereto and this Indenture; provided,
however, that amounts properly withheld under the Internal Revenue Code of 1986,
as amended, by any Person from a payment to any Holder of Securities, after
having requested such Holder to provide applicable information that would allow
such Person to make such payment without withholding, shall be considered as
having been paid by the Company to such Holder for purposes of this Indenture.
An installment of principal, premium, if any, or interest shall be considered
paid on the date it is due if there shall have been sent to the Trustee or
Paying Agent by wire transfer, or if the Trustee or Paying Agent otherwise
holds, on that date money designated for and sufficient to pay the installment.

                  Section 9.2. Maintenance of Office or Agency. Unless otherwise
specified as contemplated by Section 3.1, if Securities of a series are issued
as Registered Securities, the Company will maintain in each Place of Payment for
any series of Securities an office or agency where Securities of that series may
be presented or surrendered for payment, where Securities of that series may be
surrendered for registration of transfer or exchange and where notices and
demands to or upon the Company in respect of the Securities of that series and
this Indenture may be served. Unless otherwise specified as contemplated by
Section 3.1, if Securities of a series are issuable as Bearer Securities, the
Company will maintain, (i) subject to any laws or regulations applicable
thereto, an office or agency in a Place of Payment for that series which is
located outside the United States where Securities of that series and related
interest coupons may be presented and surrendered for payment; provided,
however, that if the Securities of that series are listed on The International
Stock Exchange of the United Kingdom and the Republic of Ireland Limited, the
Luxembourg Stock Exchange or any other stock exchange located outside the United
States and such stock exchange shall so require, the Company will maintain a
Paying Agent for the Securities of that series in London, Luxembourg or any
other required city located outside the United States, as the case may be, so
long as the Securities of that series are listed on such exchange, and (ii)
subject to any laws or regulations applicable thereto, an office or agency in a
Place of Payment for that series which is located outside the United States,
where Securities of that series may be surrendered for exchange and where
notices and demands to or upon the Company in respect of the Securities of that
series and this Indenture may be served. The Company will give prompt written
notice to the Trustee of the location, and any change in the location, of any
such office or agency. If at any time

                                       66
<PAGE>   75
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.

                  Unless otherwise specified as contemplated by Section 3.1, no
payment of principal, premium or interest on Bearer Securities shall be made at
any office or agency of the Company in the United States, by check mailed to any
address in the United States, by transfer to an account located in the United
States or upon presentation or surrender in the United States of a Bearer
Security or interest coupon for payment, even if the payment would be credited
to an account located outside the United States; provided, however, that, if the
Securities of a series are denominated and payable in Dollars, payment of
principal of and any premium or interest on any such Bearer Security shall be
made at the office of the Company's Paying Agent in the Borough of Manhattan,
The City of New York, if (but only if) payment in Dollars of the full amount of
such principal, premium or interest, as the case may be, at all offices or
agencies outside the United States maintained for the purpose by the Company in
accordance with this Indenture is illegal or effectively precluded by exchange
controls or other similar restrictions.

                  Unless otherwise specified as contemplated by Section 3.1, the
Company may also from time to time designate one or more other offices or
agencies where the Securities (including any interest coupons, if any) of one or
more series 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 each Place of Payment for
Securities (including any interest coupons, if any) of any series 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.

                  Unless otherwise specified as contemplated by Section 3.1, the
Trustee shall initially serve as Paying Agent.

                  Section 9.3. Money for Securities Payments to Be Held in
Trust; Unclaimed Money. If the Company shall at any time act as its own Paying
Agent with respect to any series of Securities and any interest coupons
appertaining thereto, it will, on or before each due date of the principal of,
premium, if any, or interest on any of the Securities of that series, segregate
and hold in trust for the benefit of the Persons entitled thereto a sum
sufficient to pay the principal, premium, if any, or interest so becoming due
until such sums shall be paid to such Persons or otherwise disposed of as herein
provided and will promptly notify the Trustee in writing of its action or
failure so to act.

                                       67
<PAGE>   76
                  Whenever the Company shall have one or more Paying Agents for
any series of Securities and any interest coupons appertaining thereto, it will,
prior to each due date of the principal of or any premium or interest on any
Securities of that series, deposit with a Paying Agent a sum sufficient to pay
such amount, such sum to be held as provided by the 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 for any series of
Securities other than the Trustee to execute and deliver to the Trustee an
instrument in which such Paying Agent shall agree with the Trustee, subject to
the provisions of this Section, that such Paying Agent will:

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

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

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

                  The Company may at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture or for any other purpose, pay, or
by Company Order direct any Paying Agent to pay, to the Trustee all sums held in
trust by the Company or such Paying Agent, such sums to be held by the Trustee
upon the terms set forth in this Indenture; 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 any principal of or
premium or interest on any Security of any series and remaining unclaimed for
two years after such principal, premium, if any, 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 such Security
and interest coupon, if any, shall thereafter, as an unsecured general creditor,
look only to the Company for payment thereof, and all liability of the Trustee
or such Paying Agent with respect to such trust money, and all liability of the
Company as trustee thereof, shall thereupon cease; provided, however, that the

an Authorized Newspaper in each Place of Payment with respect to such series, or
cause to be mailed to such Holder, notice that such money remains unclaimed and
that, after a date specified therein, which shall not be less than 30 days from
the date of such publication, any unclaimed balance of such money then remaining
will be repaid to the Company.

Company will at all times do or cause to be done all things necessary to
preserve and keep in full force and effect its corporate existence and its

shall be determined that such abandonment or termination is desirable in the
conduct of the business of the Company.

particular instance to comply with any term, provision or condition set forth in
any covenant provided pursuant to Section 3.1(15), 8.1(7) of the benefit of the
Holders of such series if before the time for such compliance the Holders of at
least a majority in principal amount of the Outstanding Securities of such
series shall, by act of such Holders in accordance with Section 1.4, either
waive such compliance in such instance or generally waive compliance with such
term, provision or condition, but no such waiver shall extend to or affect such
term, provision or condition except to the extent so expressly waived, and,
until such waiver shall become effective, the obligations of the Company and the
duties of the Trustee in respect of any such term, provision or condition shall
remain in full forth and effect.

                                   REDEMPTION

                  Section 11.1. Applicability of Article. Securities (including
interest coupons, if any) of any series which are redeemable before their Stated
Maturity shall be redeemable in accordance with their terms and (except as
otherwise specified as contemplated by Section 3.1 for Securities of any series)
in accordance with this Article.

                  Section 11.2. Election to Redeem; Notice to Trustee. The
election of the Company to redeem any Securities, including interest coupons, if
any, that, at the time of such election, may be redeemed at the option of the
Company, shall be evidenced by or pursuant to a Board Resolution. In the case of
any such redemption at the election of the Company of less than all the
Securities or interest coupons, if any, of any series, the Company shall, at
least 45 days prior to the Redemption Date fixed by the Company (unless a
shorter notice shall be satisfactory to the Trustee), notify the Trustee of such
Redemption Date, of the principal amount of Securities of such series to be
redeemed and, if applicable, of the tenor of the Securities to be redeemed. In
the case of any redemption of Securities (i) prior to the expiration of any
restriction on such redemption provided in the terms of such Securities or
elsewhere in this Indenture or (ii) pursuant to an election of the Company which
is subject to a condition specified in the terms of such Securities, the Company
shall furnish the Trustee with an Officers' Certificate evidencing compliance
with such restriction or condition.

                  Section 11.3. Selection of Securities to Be Redeemed. Unless
otherwise specified as contemplated by Section 3.1, if less than all the
Securities (including interest coupons, if any) of a series with the same terms
are to be redeemed, the Trustee, not more than 45 days prior to the Redemption
Date, shall select the Securities of the series to be redeemed in such manner as
the Trustee shall deem fair and appropriate. The Trustee shall make the
selection from Securities of the series that are Outstanding and that have not
previously been called for redemption and may provide for the selection for
redemption of portions (equal to the minimum authorized denomination for
Securities, including interest coupons, if any, of that series or any integral
multiple thereof) of the principal amount of Securities, including interest
coupons, if any, of such series of a denomination larger than the minimum
authorized denomination for Securities of that series. The Trustee shall
promptly notify the Company in writing of the Securities selected by the Trustee
for redemption and, in the case of any Securities selected for partial
redemption, the principal amount thereof to be redeemed. If the Company shall so
direct, Securities registered in the name of the Company, any Affiliate or any
Subsidiary thereof shall not be included in the Securities selected for
redemption.

                  For purposes of this Indenture, unless the context otherwise
requires, all provisions relating to the redemption of Securities (including
interest coupons, if any)

                                       72
<PAGE>   81
shall relate, in the case of any Securities (including interest coupons, if any)
redeemed or to be redeemed only in part, to the portion of the principal amount
of such Securities (including interest coupons, if any) which has been or is to
be redeemed.

                  Section 11.4. Notice of Redemption. Unless otherwise specified
as contemplated by Section 3.1, notice of redemption shall be given in the
manner provided in Section 1.6 not less than 30 days nor more than 60 days prior
to the Redemption Date to the Holders of the Securities to be redeemed.

                  All notices of redemption shall state:

                  (1) the Redemption Date;

                  (2) the Redemption Price;

                  (3) if less than all the Outstanding Securities of a series
         are to be redeemed, the identification (and, in the case of partial
         redemption, the principal amounts) of the particular Security or
         Securities to be redeemed;

                  (4) the Place or Places of Payment where such Securities,
         together in the case of Bearer Securities with all interest coupons
         appertaining thereto, if any, maturing after the Redemption Date, are
         to be surrendered for payment of the Redemption Price;

                  (5) that Securities of the series called for redemption and
         all unmatured interest coupons, if any, appertaining thereto must be
         surrendered to the Paying Agent to collect the Redemption Price;

                  (6) that, on the Redemption Date, the Redemption Price will
         become due and payable upon each such Security, or the portion thereof,
         to be redeemed and, if applicable, that interest thereon will cease to
         accrue on and after said date;

                  (7) that the redemption is from a sinking fund, if such is the
         case;

                  (8) that, unless otherwise specified in such notice, Bearer
         Securities of any series, if any, surrendered for redemption must be
         accompanied by all interest coupons maturing subsequent to the
         Redemption Date or the amount of any such missing interest coupon or
         interest coupons will be deducted from the Redemption Price, unless
         security or indemnity satisfactory to the Company, the Trustee and any
         Paying Agent is furnished;

                  (9) the CUSIP number, if any, of the Securities;

                                       73
<PAGE>   82
                  (10) if applicable, the conversion or exchange price, the date
         on which the right to convert or exchange the Securities (or portions
         thereof to be redeemed) will terminate and the place or places where
         such Securities may be surrendered for conversion or exchange; and

                  (11) the procedures that a Holder must follow to surrender the
         Securities so to be redeemed.

Notice of redemption of Securities to be redeemed shall be given by the Company
or, at the Company's request, by the Trustee in the name and at the expense of
the Company.

                  Section 11.5. Deposit of Redemption Price. On or prior to any
Redemption Date, the Company shall deposit with the Trustee or with a Paying
Agent (or, if the Company is acting as its own Paying Agent, segregate and hold
in trust as provided in Section 9.3) an amount of money in the currency or
currencies (including currency unit or units) in which the Securities of such
series are payable (except as otherwise specified pursuant to Section 3.1 for
the Securities of such series) sufficient to pay on the Redemption Date the
Redemption Price of, and (unless the Redemption Date shall be an Interest
Payment Date) interest accrued to the Redemption Date on, all Securities or
portions thereof which are to be redeemed on that date.

                  Unless any Security by its terms prohibits any redemption
obligation from being satisfied by delivering and crediting Securities
(including Securities redeemed otherwise than through a sinking fund), the
Company may deliver such Securities to the Trustee for crediting of an amount
equal to the then applicable Redemption Price for such Securities against such
payment obligation in accordance with the terms of such Securities and this
Indenture.

                  Section 11.6. Securities Payable on Redemption Date. Notice of
redemption having been given as aforesaid, the Securities so to be redeemed
shall, on the Redemption Date, become due and payable at the Redemption Price
therein specified, and from and after such date (unless the Company shall
default in the payment of the Redemption Price and accrued interest) such
Securities shall cease to bear interest and the interest coupons for any such
interest appertaining to any Bearer Security so to be redeemed, except to the
extent provided below, shall be void. Except as provided in the next succeeding
paragraph, upon surrender of any such Security, including interest coupons, if
any, for redemption in accordance with said notice, such Security shall be paid
by the Company at the Redemption Price, together with accrued interest to the
Redemption Date; provided, however, that installments of interest on Bearer
Securities whose Stated Maturity is on or prior to the Redemption Date shall be
payable only at an office or agency located outside the United States and its
possessions (except as otherwise provided in Section 9.2) and, unless otherwise
specified as contemplated by Section 3.1, only upon presentation and surrender
of interest coupons for such interest; and provided,

                                       74
<PAGE>   83
further, that, unless otherwise specified as contemplated by Section 3.1,
installments of interest on Registered Securities that are due and payable on
Interest Payment Dates that are on or prior to the Redemption Date shall be
payable to the Holders of such Securities, or one or more Predecessor
Securities, registered as such at the close of business on the relevant Regular
Record Dates according to their terms and the provisions of Section 3.7.

                  If any Bearer Security surrendered for redemption shall not be
accompanied by all appurtenant interest coupons maturing after the Redemption
Date, such Bearer Security may be paid after deducting from the Redemption Price
an amount equal to the face amount of all such missing interest coupons, or the
surrender of such missing interest coupon or interest coupons may be waived by
the Company and the Trustee if there be furnished to them such security or
indemnity as they may require to save each of them and any Paying Agent
harmless. If thereafter the Holder of such Bearer Security shall surrender to
the Trustee or any Paying Agent any such missing interest coupon in respect of
which a deduction shall have been made from the Redemption Price, such Holder
shall be entitled to receive the amount so deducted; provided, however, that
interest represented by interest coupons shall be payable only at an office or
agency located outside of the United States (except as otherwise provided
pursuant to Section 9.2) and, unless otherwise specified as contemplated by
Section 3.1, only upon presentation and surrender of those interest coupons.

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

                  Section 11.7. Securities Redeemed in Part. Upon surrender of a
Security that is redeemed in part at any Place of Payment therefor (with, if the
Company or the Trustee so required, 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 or her attorney duly authorized in writing), the
Company shall execute and the Trustee shall authenticate and deliver to the
Holder of that Security, without service charge, a new Security or Securities of
the same series, having the same form, terms and Stated Maturity, in any
authorized denomination equal in aggregate principal amount to the unredeemed
portion of the principal amount of the Security surrendered.

Article shall be applicable to any sinking fund for the retirement of Securities
of a series except as otherwise specified as contemplated by Section 3.1 for
Securities of such series.

                  The minimum amount of any sinking fund payment provided for by
the terms of Securities of any series is herein referred to as a "mandatory
sinking fund payment," and any payment in excess of such minimum amount provided
for by the terms of Securities of any series is herein referred to as an
"optional sinking fund payment." If provided for by the terms of Securities of
any series, the cash amount of any sinking fund payment may be subject to
reduction as provided in Section 12.2. Each sinking fund payment shall be
applied to the redemption of Securities of any series as provided for by the
terms of Securities of such series.

Securities. The Company (i) may deliver Outstanding Securities of a series
(other than any previously called for redemption) together, in the case of
Bearer Securities of such series, with all unmatured interest coupons
appertaining thereto and (ii) may apply as a credit Securities of a series which
have been (x) redeemed either at the election of the Company pursuant to the
terms of such Securities or through the application of permitted optional
sinking fund payments pursuant to the terms of such Securities, (y) converted or
exchanged pursuant to Article 14 or (z) previously delivered to the Trustee and
cancelled without reissuance pursuant to Section 3.9, in each case in
satisfaction of all or any part of any sinking fund payment with respect to the
Securities of such series required to be made pursuant to the terms of such
Securities as provided for by the terms of such series; provided that such
Securities have not been previously so credited. Such Securities shall be
received and credited for such purpose by the Trustee at the Redemption Price
specified in such Securities for redemption through operation of the sinking
fund and the amount of such sinking fund payment shall be reduced accordingly.

                  Section 12.3. Redemption of Securities for Sinking Fund. Not
less than 45 days prior to each sinking fund payment date for any series of
Securities, the Company will deliver to the Trustee an Officers' Certificate
specifying the amount of the next ensuing sinking fund payment for that series
pursuant to the terms of that series, the portion thereof, if any, which is to
be satisfied by payment of cash and the portion thereof, if any, which is to be
satisfied by delivering and crediting Securities of that series pursuant to
Section 12.2 and stating the basis for such credit and that such Securities have
not been previously so credited, and will also deliver to the Trustee any
Securities to be so delivered. Not less than 30 days before each such sinking
fund payment date the Trustee shall select the Securities to be redeemed upon
such sinking fund payment date in

such Securities shall be made upon the terms and in the manner stated in
Sections 11.6 and 11.7.

of a series may be adopted at a meeting or an adjourned meeting duly reconvened
and at which a quorum is present as aforesaid by the affirmative vote of the
lesser of (i) the Holders of such specified percentage in principal amount of
the Outstanding Securities of such series and (ii) a majority in principal
amount of Outstanding Securities of such series represented and voting at such
meeting or adjourned meeting.

                  Any resolution passed or decisions taken at any meeting of
Holders of Securities of any series issuable as Bearer Securities duly held in
accordance with this

                                       78
<PAGE>   87
Section shall be binding on all the Holders of Securities of such series and
interest coupons, whether or not present or represented at the meeting.

                  In the event that any meeting shall be adjourned for lack of a
quorum or that, at any meeting at which a quorum is present, any proposed
resolution or decision shall not be passed or taken because the Holders of the
percentage of Outstanding Securities of any series issuable as Bearer Securities
needed to approve such resolution or decision did not vote in favor of such
resolution or decision, the principal amount of Outstanding Securities of such
series represented at such meeting and voting in favor of such resolution or
decision may be counted for purposes of calculating whether the consent of the
Holders of the percentage of Outstanding Securities of such series needed in
order to make, give or take any request, demand, authorization, direction,
notice, consent, election, waiver or other action has been obtained, and such
vote shall constitute the consent thereto of such Holders.

                  Section 13.5. Determination of Voting Rights; Conduct and
Adjournment of Meetings. (a) Notwithstanding any other provisions of this
Indenture, the Trustee may make such reasonable regulations as it may deem
advisable for any meeting of Holders of Securities of any series issuable as
Bearer Securities in regard to proof of the holding of Securities of such series
and of the appointment of proxies and in regard to the appointment and duties of
inspectors of votes, the submission and examination of proxies, certificates and
other evidence of the right to vote, and such other matters concerning the
conduct of the meeting as it shall deem appropriate. Except as otherwise
permitted or required by any such regulations, the holding of Securities of a
series issuable as Bearer Securities shall be proved in the manner specified in
Section 1.4 and the appointment of any proxy shall be provided in the manner
specified in Section 1.4 or by having the signature of the Person executing the
proxy witnessed or guaranteed by any trust company, bank or banker authorized by
Section 1.4 to certify to the holding of Bearer Securities. Such regulations may
provide that written instruments appointing proxies, regular on their face, may
be presumed valid and genuine without the proof specified in Section 1.4 or
other proof.

                  (b) The Trustee shall, by an instrument in writing, appoint a
temporary chairman (which may be a Responsible Officer of the Trustee) of the
meeting, unless the meeting shall have been called by the Company or by Holders
of Securities of a series as provided in Section 13.2(b), in which case the
Company or the Holders of Securities of such series calling the meeting, as the
case may be, shall in like manner appoint a temporary chairman. A permanent
chairman and a permanent secretary of the meeting shall be elected by vote of
the Persons entitled to vote a majority in principal amount of the Outstanding
Securities of such series represented at the meeting.

<PAGE>   88
                  (c) At any meeting each Holder of a Security or proxy shall be
entitled to one vote for each U.S. $5,000 principal amount of Securities held or
represented by him or her; provided, however, that no vote shall be cast or
counted at any meeting in respect of any Security challenged as not Outstanding
and ruled by the chairman of the meeting to be not Outstanding. The chairman of
the meeting shall have no right to vote, except as a Holder of a Security or
proxy.

                  (d) Any meeting of Holders of Securities of a series issuable
as Bearer Securities duly called pursuant to Section 13.2 at which a quorum is
present may be adjourned from time to time by Persons entitled to vote a
majority in principal amount of the Outstanding Securities of such series
represented at the meeting, and the meeting may be held as so adjourned without
further notice.

                  Section 13.6. Counting Votes and Recording Action of Meetings.
The vote upon any resolution submitted to any meeting of Holders of Securities
of any series issuable as Bearer Securities shall be by written ballots on which
shall be subscribed the signatures of the Holders of Securities of such series
or of their representatives by proxy and the principal amounts and serial
numbers of the Outstanding Securities held or represented by them. The permanent
chairman of the meeting shall appoint an inspector of votes who shall count all
votes cast at the meeting for or against any resolution and who shall make and
file with the secretary of the meeting its verified written report of all votes
cast at the meeting. A record of the proceedings of each meeting of Holders of
Securities shall be prepared by the applicable secretary of the meeting and
there shall be attached to said record the original report of the inspector of
votes on any vote by ballot taken thereat and affidavits by one or more Persons
having knowledge of the facts setting forth a copy of the notice of the meeting
and showing that said notice was given as provided in Section 13.2 and, if
applicable, Section 13.4. At least two copies of such record shall be signed and
verified by the affidavits of the permanent chairman and secretary of the
meeting and one copy thereof shall be delivered to the Company and the other to
the Trustee to be preserved by the Trustee, the latter to have attached thereto
the ballots voted at the meeting. Any record so signed and verified shall be
conclusive evidence of the matters therein stated.

                                   ARTICLE 14

                      CONVERSION OR EXCHANGE OF SECURITIES

                  Section 14.1. Applicability of Article. (a) The provisions of
this Article 14 shall be applicable to the Securities of any series which are
convertible or exchangeable into Equity Securities of the Company, and to the
issuance of such Equity Securities upon the conversion or exchange of such
Securities, except as otherwise specified as contemplated by Section 3.1 for the
Securities of such series.

                  (b) For purposes of this Article 14, the term "Equity
Securities" shall mean all or any of the following, authorized from time to
time: (i) the Company's Common Stock, $.01 par value (the "Common Stock"), (ii)
the Company's Preferred Stock, $.10 par value (the "Preferred Stock"), and (iii)
any other equity securities of the Company.

                  Section 14.2. Exercise of Conversion or Exchange Privilege.
(a) In order to exercise a conversion or exchange privilege, the Holder of a
Security of a series with such privilege shall surrender such Security,
together, in the case of any Bearer Security, with all unmatured interest
coupons and any matured interest coupons in default appertaining thereto, to the
Company at the office or agency maintained for that purpose pursuant to Section
9.2, accompanied by written notice to the Company that the Holder elects to
convert or exchange such Security or a specified portion thereof. Such notice
shall also state, if different from the name and address of such Holder, the
name or names (with address) in which the certificate or certificates for Equity
Securities which shall be issuable on such conversion or exchange shall be
issued. Registered Securities surrendered for conversion or exchange shall (if
so required by the Company or the Trustee) be duly endorsed by or accompanied by
instruments of transfer in forms satisfactory to the Company and the Trustee
duly executed by the registered Holder or its attorney duly authorized in
writing.

                  (b) Registered Securities so surrendered for conversion or
exchange during the period from the close of business on any Regular Record Date
to the opening of business on the corresponding Interest Payment Date (excluding
Securities or portions thereof called for redemption during such period) shall
also be accompanied by payment in funds acceptable to the Company of an amount
equal to the interest payable on such Interest Payment Date on the principal
amount of such Security then being converted or exchanged, and such interest
shall be payable to such registered Holder on such Interest Payment Date
notwithstanding the conversion or exchange of such Security, subject to the
provisions of Section 3.7 relating to the payment of Defaulted Interest by the
Company.

                                       81
<PAGE>   90
                  (c) As promptly as practicable after the receipt of such
notice and of any payment required pursuant to a Board Resolution and, subject
to Section 3.3, set forth, or determined in the manner provided, in an Officers'
Certificate, or established in one or more indentures supplemental hereto
setting forth the terms of such series of Security, and the surrender of such
Security in accordance with such reasonable regulations as the Company may
prescribe, the Company shall issue and shall deliver, at the office or agency at
which such Security is surrendered, to such Holder or on its written order, a
certificate or certificates for the number of Equity Securities issuable upon
the conversion or exchange of such Security (or specified portion thereof), in
accordance with the provisions of such Board Resolution, Officers' Certificate
or supplemental indenture, and cash as provided therein in respect of any
fractional share of such Equity Security otherwise issuable upon such conversion
or exchange.

                  (d) Such conversion or exchange shall be deemed to have been
effected immediately prior to the close of business on the date on which such
notice and such payment, if required, shall have been received in proper order
for conversion or exchange by the Company and such Security shall have been
surrendered as aforesaid and at such time the rights of the Holder of such
Security as such Security Holder shall cease and the person or persons in whose
name or names any certificate or certificates for Equity Securities of the
Company shall be issuable upon such conversion or exchange shall be deemed to
have become the Holder or Holders of record of the Equity Securities represented
thereby. Except as set forth above and subject to paragraph (d) of Section 3.7,
no payment or adjustment shall be made upon any conversion or exchange on
account of any interest accrued on the Securities surrendered for conversion or
exchange, or on account of any dividends on the Equity Securities of the Company
issued upon such conversion or exchange if the record date for the payment of
such dividends occurs prior to or on the date on which such conversion or
exchange shall be deemed to have been effected.

                  In the case of any Security which is converted or exchanged in
part only, upon such conversion or exchange the Company shall execute and the
Trustee shall authenticate and deliver to or on the order of the Holder thereof,
at the expense of the Company, a new Security or Securities of the same series,
of authorized denominations, in aggregate principal amount equal to the
unconverted or unexchanged portion of such Security.

                  Section 14.3. No Fractional Equity Securities. No fractional
Equity Security of the Company shall be issued upon conversions or exchanges of
Securities of any series. If more than one Security shall be surrendered for
conversion or exchange at one time by the same Holder, the number of full shares
of the Equity Security which shall be issuable upon conversion or exchange shall
be computed on the basis of the aggregate principal amount of the Securities (or
specified portions thereof to the extent permitted

                                       82
<PAGE>   91
hereby) so surrendered. If, except for the provisions of this Section 14.3, any
Holder of a Security or Securities would be entitled to a fractional share of
any Equity Security of the Company upon the conversion or exchange of such
Security or Securities, or specified portions thereof, the Company shall pay to
such Holder an amount in cash equal to the current market value of such
fractional share computed, (i) if such Equity Security is listed or admitted to
unlisted trading privileges on a national securities exchange, on the basis of
the last reported sale price regular way on the principal exchange where such
Equity Security is listed or admitted, on the last trading day prior to the date
of conversion or exchange upon which such a sale shall have been effected, (ii)
if such Equity Security is not at the time so listed or admitted on a national
securities exchange but is quoted on the National Market System of the National
Association of Securities Dealers, Inc. ("NASDAQ"), on the basis of the average
of the bid and asked prices of such Equity Security on NASDAQ on the last
trading day prior to the date of conversion or exchange, (iii) if such Equity
Security is not at the time so listed or admitted to unlisted trading privileges
on a national securities exchange or quoted on NASDAQ, on the basis of the
average of the bid and asked prices of such Equity Security in the
over-the-counter market, on the last trading day prior to the date of conversion
or exchange, as reported by the National Quotation Bureau Incorporated or
similar organization if the National Quotation Bureau Incorporated is no longer
reporting such information, or (iv) in accordance with the terms of the
supplemental indenture or Board Resolutions setting the terms of the Securities
of such series. For purposes of this Section, "trading day" shall mean each
Monday, Tuesday, Wednesday, Thursday and Friday other than any day on which the
applicable Equity Security is not traded or quoted on a national securities
exchange, or if the applicable Equity Security is not traded or quoted on a
national securities exchange, on NASDAQ or the principal exchange or market on
which the applicable Equity Security is traded or quoted.

                  Section 14.4. Adjustment of Conversion or Exchange Price;
Consolidation or Merger. The conversion or exchange price of Securities of any
series that is convertible or exchangeable into an Equity Security of the
Company shall be adjusted for any stock dividends, stock splits,
reclassification, combinations or similar transactions, and the securities,
assets or other property into or for which such Securities may be converted or
exchanged as a result of any consolidation, merger, combination or similar
transaction shall be determined, in accordance with the terms of the
supplemental indenture or Board Resolutions setting the terms of the Securities
of such series.

                  Whenever the conversion or exchange price is adjusted, the
Company shall compute the adjusted conversion or exchange price in accordance
with the terms of the applicable Board Resolution or supplemental indenture and
shall prepare an Officers' Certificate setting forth the adjusted conversion or
exchange price and showing in reasonable detail the facts upon which such
adjustment is based. Whenever the securities, assets or other property into or
for which Securities of any series may be converted or

                                       83
<PAGE>   92
exchanged are changed as a result of any consolidation, merger or similar
transaction, the Company shall determine the nature and amount of such
securities, assets or other property in accordance with the terms of the
applicable Board Resolution or supplemental indenture and shall prepare an
Officer's Certificate describing such securities, assets or other property and
stating the amount of such securities, assets or other property into or for
which such Securities have become convertible or exchangeable. Such certificates
shall forthwith be filed at each office or agency maintained for the purpose of
conversion or exchange of Securities pursuant to Section 9.2 and, if different,
with the Trustee. The Company shall forthwith cause a notice setting forth the
adjusted conversion or exchange price or describing such securities, assets or
other property, as applicable, to be mailed, first class postage prepaid, to
each Holder of Registered Securities of such series at its address appearing on
the Register and to any conversion or exchange agent other than the Trustee.

                  Section 14.5. Notice of Certain Corporate Actions. If any
series of Securities which are directly or indirectly convertible or
exchangeable for any Equity Securities are Outstanding, in case:

                  (a) the Company shall declare a dividend (or any other
distribution) on any class of such Equity Securities payable otherwise than in
cash out of its retained earnings (other than a dividend for which approval of
any stockholder of the Company is required); or

                  (b) the Company shall authorize the granting to the holders of
any class of such Equity Securities of rights, options or warrants to subscribe
for or purchase any shares of capital stock of any class or of any other rights
(other than any such grant for which approval of any stockholder of the Company
is required); or

                  (c) of any reclassification of any class of such Equity
Securities (other than a subdivision or combination of its outstanding Equity
Securities, or of any consolidation, merger or share exchange to which the
Company is a party and for which approval of any stockholder of the Company is
required), or of the sale of all or substantially all of the assets of the
Company; or

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

then the Company shall cause to be filed with the Trustee, and shall cause to be
mailed to all Holders at their addresses as they shall appear in the Register,
at least 15 days (or 10 days in any case specified in clause (a) or (b) above)
prior to the applicable record date hereinafter specified, a notice stating (i)
the date on which a record is to be taken for the purpose of such dividend,
distribution, rights, options or warrants, or, if a record is not to

                                       84
<PAGE>   93
be taken, the date as of which the Holders of such Equity Securities of record
to be entitled to such dividend, distribution, rights, options or warrants are
to be determined, or (ii) the date on which such reclassification,
consolidation, merger, share exchange, sale, dissolution, liquidation or winding
up is expected to become effective, and the date as of which it is expected that
holders of such Equity Securities of record shall be entitled to exchange such
Equity Securities for securities, cash or other property deliverable upon such
reclassification, consolidation, merger, share exchange, sale, dissolution,
liquidation or winding up. If at any time the Trustee shall not be the
conversion or exchange agent, a copy of such notice shall also forthwith be
filed by the Company with the Trustee.

                  Section 14.6. Reservation of Equity Securities . The Company
shall at all times reserve and keep available, free from preemptive rights, out
of its authorized but unissued Equity Securities, for the purpose of effecting
the conversion or exchange of Securities, the full number of Equity Securities
of the Company then issuable upon the conversion or exchange of all Outstanding
Securities of any series that has conversion or exchange rights.

                  Section 14.7. Payment of Certain Taxes Upon Conversion or
Exchange. The Company will pay any and all taxes that may be payable in respect
of the issue or delivery of its Equity Securities on conversion or exchange of
Securities pursuant hereto. The Company shall not, however, be required to pay
any tax which may be payable in respect of any transfer involved in the issue
and delivery of its Equity Securities in a name other than that of the Holder of
the Security or Securities to be converted or exchanged, and no such issue or
delivery shall be made unless and until the Person requesting such issue has
paid to the Company the amount of any such tax, or has established, to the
satisfaction of the Company, that such tax has been paid.

                  Section 14.8. Duties of Trustee Regarding Conversion or
Exchange. Neither the Trustee nor any conversion or exchange agent shall at any
time be under any duty or responsibility to any Holder of Securities of any
series that is convertible or exchangeable into Equity Securities of the Company
to determine whether any facts exist which may require any adjustment of the
conversion or exchange price, or with respect to the nature or extent of any
such adjustment when made, or with respect to the method employed, whether
herein or in any supplemental indenture, any resolutions of the Board of
Directors or written instrument executed by one or more officers of the Company
provided to be employed in making the same. Neither the Trustee nor any
conversion or exchange agent shall be accountable with respect to the validity
or value (or the kind or amount) of any Equity Securities of the Company, or of
any securities or property, which may at any time be issued or delivered upon
the conversion or exchange of any Securities and neither the Trustee nor any
conversion or exchange agent makes any representation with respect thereto.
Subject to the provisions of Section 6.1, neither the Trustee nor any conversion
or exchange agent shall be responsible for any failure of the Company to

                                       85
<PAGE>   94
issue, transfer or deliver any of its Equity Securities or stock certificates or
other securities or property upon the surrender of any Security for the purpose
of conversion or exchange or to comply with any of the covenants of the Company
contained in this Article 14 or in the applicable supplemental indenture,
resolutions of the Board of Directors or written instrument executed by one or
more duly authorized officers of the Company.

                  Section 14.9. Repayment of Certain Funds Upon Conversion or
Exchange. Any funds which at any time have been deposited by the Company or on
its behalf with the Trustee or any Paying Agent for the purpose of paying the

         Section 1.2. Compliance Certificates and Opinions. Upon any application
or request by the Company to the Trustee to take any action under any provision
of this Indenture, the Company shall furnish to the Trustee such certificates
and opinions as may be required under the Trust Indenture Act (including Section
314(c) of the Trust Indenture Act). Each such certificate or opinion shall be
given in the form of an Officers' Certificate, if to be given by an officer or
officers of the Company, or an Opinion of Counsel, if to be given by counsel,
and shall comply with the requirements of the Trust Indenture Act and any other
requirements set forth in this Indenture.

         Every certificate or opinion with respect to compliance with a
condition or covenant provided for in this Indenture (other than pursuant to
Section 2.3, the last paragraph of Section 3.3 and Section 9.7) shall include:

                                       13
<PAGE>   22
                  (1) a statement that each individual signing such certificate
or opinion has read such condition or covenant and the definitions herein
relating thereto;

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

                  (3) a statement that, in the opinion of each such individual,
he or she has made such examination or investigation as is necessary to enable
him or her to express an informed opinion as to whether or not such condition or
covenant has been complied with; and

                  (4) a statement as to whether, in the opinion of each such
individual, such condition or covenant has been complied with.

         Section 1.3. Form of Documents Delivered to Trustee. In any case where
several matters are required to be certified by, or covered by an opinion of,
any specified Person, it is not necessary that all such matters be certified by,
or covered by the opinion of, only one such Person, or that they be so certified
or covered by only one document, but one such Person may certify or give an
opinion with respect to some matters and one or more other such Persons as to
other matters, and any such Person may certify or give an opinion as to such
matters in one or several documents.

         Any certificate or opinion of an officer of the Company may be based,
insofar as it relates to legal matters, upon a certificate or opinion of, or
representations by, counsel, unless such officer knows, or in the exercise of
reasonable care should know, that the certificate or opinion or representations
with respect to the matters upon which his or her certificate or opinion is
based are erroneous. Any such certificate or opinion or any Opinion of Counsel
may be based, insofar as it relates to factual matters, upon a certificate or
opinion of, or representations by, an officer or officers of the Company stating
that the information with respect to such factual matters is in the possession
of the Company, unless such officer or counsel knows, or in the exercise of
reasonable care should know, that the certificate or opinion or representations
as to such matters are erroneous.

         Any certificate, statement or opinion of an officer of the Company or
of counsel may be based, insofar as it relates to accounting matters, upon a
certificate or opinion of or representations by an accountant or firm of
accountants


                                       14
<PAGE>   23
in the employ of the Company, unless such officer or counsel, as the case may
be, knows, or in the exercise of reasonable care should know, that the
certificate or opinion or representations with respect to the accounting matters
upon which his certificate, statement or opinion is based are erroneous.

         Where any Person is required to make, give or execute two or more
applications, requests, consents, certificates, statements, opinions or other
instruments under this Indenture, they may, but need not, be consolidated and
form one instrument.

         Section 1.4. Acts of Holders. (a) Any request, demand, authorization,
direction, notice, consent, waiver or other action provided by this Indenture to
be given or taken by Holders may be embodied in and evidenced by one or more
instruments of substantially similar tenor signed (either physically or by means
of a facsimile or an electronic transmission, provided, in the case of an
electronic transmission, that it is transmitted through the facilities of a
Depositary) by such Holders in person or by agent or proxy duly appointed in
writing. If Securities of a series are issuable as Bearer Securities, any
request, demand, authorization, direction, notice, consent, waiver or other
action provided by this Indenture to be given or taken by Holders of Securities
of such series may, alternatively, be embodied in and evidenced by the record of
Holders of Securities of such series voting in favor thereof pursuant to the
third paragraph of Section 13.4, either in person or by proxies duly appointed
in writing, at any meeting of Holders of Securities of such series duly called
and held in accordance with the provisions of Article 13, or a combination of
such instruments and any such record. Except as herein otherwise expressly
provided, such action shall become effective when such instrument or instruments
or record or both are received (either physically or by means of a facsimile or
an electronic transmission, provided, in the case of an electronic transmission,
that it is transmitted through the facilities of a Depositary) by the Trustee
and, where it is hereby expressly required, to the Company. Such instrument or
instruments and record (and the action embodied therein and evidenced thereby)
are herein sometimes referred to as the "Act" of the Holders signing such
instrument or instruments or, in the case of Holders of Securities of a series
issuable as Bearer Securities, so voting at such meeting. The Company and the
Trustee may assume that any Act of a Holder has not been modified or revoked
unless written notice to the contrary is received prior to the time that the
action to which such Act relates has become effective. Proof of execution of any
such instrument or of a writing appointing any such agent shall be sufficient
for any purpose of this Indenture and (subject to Section 315 of the Trust
Indenture Act) conclusive in favor of the Trustee and the Company, if made in
the manner provided in this Section. The record of any meeting of Holders of

                                       15
<PAGE>   24
Securities issuable as Bearer Securities shall be proved in the manner provided
in Section 13.6.

                  (b) The fact and date of the execution by any Person of any
such instrument or writing and the authority of the Person executing the same
may be proved in any manner which the Trustee deems sufficient.

                  (c) The ownership of Bearer Securities may be proved by the
production of such Bearer Securities or by a certificate executed by any trust
company, bank, banker or other depository, wherever situated, if such
certificate shall be deemed by the Trustee to be satisfactory, showing that at
the date therein mentioned such Person had on deposit with such trust company,
bank, banker or other depository, or exhibited to it, the Bearer Securities
therein described; or such facts may be proved by the certificate or affidavit
of the Person holding such Bearer Securities, if such certificate or affidavit
is deemed by the Trustee to be satisfactory. The Trustee and the Company may
assume that such ownership of any Bearer Security continues until (i) another
such certificate or affidavit bearing a later date issued in respect of the same
Bearer Security is produced, (ii) such Bearer Security is produced to the
Trustee by some other Person, (iii) such Bearer Security is surrendered in
exchange for a Registered Security or (iv) such Bearer Security is no longer
Outstanding. The ownership of Bearer Securities may also be proved in any other
manner which the Trustee deems sufficient.

                  (d) The ownership of Registered Securities shall be proved by
the Register.

                  (e) Any request, demand, authorization, direction, notice,
consent, waiver or other Act of the Holder of any Security shall bind every
future Holder of the same Security and any interest coupons appertaining thereto
and the Holder of every Security or interest coupon 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 Act is made upon such Security
or interest coupon.

                  (f) If the Company shall solicit from the Holders any request,
demand, authorization, direction, notice, consent, waiver or other Act, the
Company may, at its option, by or pursuant to a Board Resolution, fix in advance
a record date for the determination of Holders of Registered Securities entitled
to give such request, demand, authorization, direction, notice, consent, waiver
or other Act, but the Company shall have no obligation to do so. Notwithstanding
Section 316(c) of the Trust Indenture Act, any such record

                                       16
<PAGE>   25
date shall be the record date specified in or pursuant to such Board Resolution,
which shall be a date not more than 30 days prior to the first solicitation of
Holders generally in connection therewith and no later than the date such first
solicitation is completed. If such a record date is fixed, such request, demand,
authorization, direction, notice, consent, waiver or other Act may be given
before or after such record date, but only the Holders of Registered Securities
of record at the close of business on such record date shall be deemed to be
Holders for the purposes of determining whether Holders of the requisite
proportion of Outstanding Securities have authorized or agreed or consented to
such request, demand, authorization, direction, notice, consent, waiver or other
Act, and for that purpose the Outstanding Securities shall be computed as of
such record date; provided that no such authorization, agreement or consent by
the Holders on such record date shall be deemed effective unless it shall become
effective pursuant to the provisions of this Indenture not later than six months
after the record date.

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

                  Section 1.5. Notices, etc., to Trustee and 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,

                  (1) 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 Department, or at any other address
         previously furnished in writing to the Holders or the Company by the
         Trustee, or, with respect to notices by the Company, transmitted by
         facsimile transmission (confirmed by guaranteed overnight courier) to
         the following facsimile number: (612) 244-0711 or to any other
         facsimile number previously furnished in writing to the Company by the
         Trustee, or

                  (2) 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 it addressed to it at the address of the Company's
         principal office specified in

                                       17
<PAGE>   26
         the first paragraph of this instrument or at any other address
         previously furnished in writing to the Trustee by the Company or, with
         respect to notices by the Trustee, transmitted by facsimile
         transmission (confirmed by guaranteed overnight courier) to the
         following facsimile number: (602) 423-9424 or to any other facsimile
         number previously furnished in writing to the Trustee by the Company.

                  Section 1.6. Notice to Holders; Waiver. Where this Indenture
provides for notice to Holders of any event, (i) if any of the Securities
affected by such event are Registered Securities, such notice to the Holders
thereof shall be sufficiently given (unless otherwise herein expressly provided)
if in writing and mailed, first-class postage prepaid, to each such Holder
affected by such event, at his or her address as it appears in the Register,
within the time prescribed for the giving of such notice, and (ii) if any of the
Securities affected by such event are Bearer Securities, notice to the Holders
thereof shall be sufficiently given (unless otherwise herein or in the terms of
such Bearer Securities expressly provided) if published once in an Authorized
Newspaper in New York, New York, and in such other city or cities, if any, as
may be specified as contemplated by Section 3.1. Such notices shall be deemed to
have been given on the date of such mailing or publication.

                  In any case where notice to Holders is given by mail or by
publication, neither the failure to mail or publish such notice, nor any defect
in any notice so mailed or published, to any particular Holder shall affect the
sufficiency of such notice with respect to other Holders of Registered
Securities or of Bearer Securities. Any notice mailed to a Holder in the manner
herein prescribed shall be conclusively deemed to have been received by such
Holder, whether or not such Holder actually receives such notice.

                  If by reason of the suspension of regular mail service or by
reason of any other cause it shall be impracticable to give such notice as
provided above, then such notification as shall be made with the approval of the
Trustee shall constitute a sufficient notification for every purpose hereunder.
If it is impossible or, in the opinion of the Trustee, impracticable to give any
notice by publication in the manner herein required, then such publication in
lieu thereof as shall be made with the approval of the Trustee shall constitute
a sufficient publication of such notice.

                  Any request, demand, authorization, direction, notice, consent
or waiver required or permitted under this Indenture shall be in the English
language,

                                       18
<PAGE>   27
except that any published notice may be in an official language of the country
of publication.

                  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 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 suspension of regular mail service or 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
sufficient notification for every purpose hereunder.

                  Section 1.7. Headings and Table of Contents. The Article and
Section headings herein and the Table of Contents are for convenience only and
shall not affect the construction hereof.

                  Section 1.8. Successor and Assigns. All covenants and
agreements in this Indenture by the Company shall bind its successors and
assigns, whether so expressed or not.

                  Section 1.9. Separability.
                  In case any provision of this Indenture or the Securities
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 1.10. Benefits of Indenture. Nothing in this Indenture
or in the Securities, expressed or implied, shall give to any Person, other than
the parties hereto and their successors hereunder and the Holders, any benefit
or any legal or equitable right, remedy or claim under this Indenture.

                  Section 1.11. Incorporators, Stockholders, Officers and
Directors of the Company Exempt from Individual Liability. No recourse under or
upon any obligation, covenant or agreement of or contained in this Indenture or
of or contained in any Security or interest coupon appertaining thereto, or for
any claim based thereon or otherwise in respect thereof, or because of any
indebtedness represented thereby, shall be had against any incorporator,
stockholder, officer or director, as such, past, present or future, of the
Company or any successor Person, either directly or through the Company or any
successor Person, whether by virtue


                                       19
<PAGE>   28
of any constitution, statute or rule of law, by the enforcement of any
assessment or penalty, by any legal or equitable proceeding or otherwise; it
being expressly understood that all such liability is hereby expressly waived
and released as a condition of the acceptance of, and as a part of the
consideration for the execution of this Indenture and the issuance of, the
Securities and any interest coupons appertaining thereto.

                  Section 1.12. Governing Law; Conflict with Trust Indenture
Act. THIS INDENTURE, THE SECURITIES AND ANY INTEREST COUPONS APPERTAINING
THERETO SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE
STATE OF NEW YORK. This Indenture is subject to the Trust Indenture Act and if
any provision hereof limits, qualifies or conflicts with the Trust Indenture
Act, the Trust Indenture Act shall control. Whether or not this Indenture is
required to be qualified under the Trust Indenture Act, the provisions of the
Trust Indenture Act required to be included in an indenture in order for such
indenture to be so qualified shall be deemed to be included in this Indenture
with the same effect as if such provisions were set forth herein and any
provisions hereof which may not be included in an indenture which is so
qualified shall be deemed to be deleted or modified to the extent such
provisions would be required to be deleted or modified in an indenture so
qualified.

                  Section 1.13. Legal Holidays. In any case where any Interest
Payment Date, Redemption Date, sinking fund payment date, Stated Maturity or
Maturity of any Security shall not be a Business Day at any Place of Payment,
then (notwithstanding any other provision of this Indenture or of any Security
or interest coupon other than a provision in the Securities of any series which
specifically states that such provision shall apply in lieu of this Section),
payment of principal, premium, if any, or interest need not be made at such
Place of Payment on such date, but may be made on the next succeeding Business
Day at such Place of Payment with the same force and effect as if made on such
date; provided that no interest shall accrue on the amount so payable for the
period from and after such Interest Payment Date, Redemption Date, sinking fund
payment date, Stated Maturity or Maturity, as the case may be, if such amount is
so paid on the next succeeding Business Day.

          Section 1.14. Moneys of Different Currencies to Be Segregated. The
Trustee shall segregate all moneys, funds and accounts held by the Trustee
hereunder in one currency from any moneys, funds and accounts held by the
Trustee hereunder in one currency from any moneys, funds or accounts in any

                                       20
<PAGE>   29
other currencies, notwithstanding any provision herein which would otherwise
permit the Trustee to commingle such amounts.

                  Section 1.15. Independence of Covenants. All covenants and
agreements in this Indenture shall be given independent effect so that if a
particular action or condition is not permitted by any such covenant, the fact
that it would be permitted by an exception to, or be otherwise within the
limitations of, another covenant shall not avoid the occurrence of a Default or
an Event of Default if such action is taken or condition exists.

                  Section 1.16. Counterparts. This Indenture may be executed in
any number of counterparts, each of which shall be an original, but such
counterparts shall together constitute but one and the same instrument.

                                    ARTICLE 2

                                 SECURITY FORMS

                  Section 2.1. Forms Generally. The Securities of each series
and the interest coupons, if any, to be attached thereto shall be in
substantially such form as shall be established by or pursuant to a Board
Resolution or in one or more indentures supplemental hereto, in each case with
such appropriate insertions, omissions, substitutions and other variations as
are required or permitted by this Indenture, and may have such letters, numbers
or other marks of identification and such legends or endorsements placed thereon
as may be required to comply with the rules of any applicable securities
exchange, organizational document, governing instrument or law or as may,
consistently herewith, be determined by the officers executing such Securities
and interest coupons, if any, as evidenced by their execution of the Securities
and interest coupons, if any. If temporary Securities of any series are issued
as permitted by Section 3.4, the form thereof also shall be established as
provided in the preceding sentence. If the forms of Securities and interest
coupons, if any, of any series are established by, or by action taken pursuant
to, a Board Resolution, a copy of the Board Resolution together with an
appropriate record of any such action taken pursuant thereto, including a copy
of the approved form of Securities or interest coupons, if any, shall be
delivered to the Trustee at or prior to the delivery of the Company Order
contemplated by Section 3.3 for the authentication and delivery of such
Securities.

                  Unless otherwise specified as contemplated by Section 3.1,
Bearer Securities shall have interest coupons attached.

<PAGE>   30
                  The definitive Securities and interest coupons, if any, may be
printed, lithographed or engraved on steel engraved borders or may be produced
in any other manner (or, if such Securities are listed on any securities
exchange, any other manner permitted by the rules of such securities exchange),
all as determined by the officers executing such Securities and interest
coupons, if any, as evidenced by their execution of such Securities and interest
coupons, if any.

                  Section 2.2. Form of Trustee's Certificate of Authentication.
The Trustee's certificate of authentication shall be in substantially the
following form:

                  This is one of the Securities of the series described in the
within-mentioned Indenture.

                                            FIRST BANK NATIONAL ASSOCIATION,
                                            as Trustee


                                            By:

          Section 2.3. Securities in Global Form. If Securities of or within a
series are issuable in whole or in part in global form, any such Security may
provide that it shall represent the aggregate or specified amount of Outstanding
Securities from time to time endorsed thereon and may also provide that the
aggregate amount of Outstanding Securities represented thereby may from time to
time be reduced or increased to reflect exchanges. Any endorsement of a Security
in global form to reflect the amount, or any increase or decrease in the amount,
or changes in the rights of Holders, of Outstanding Securities represented
thereby, shall be made in such manner and by such Person or Persons as shall be
specified therein or in the Company Order to be delivered to the Trustee
pursuant to Section 3.3 or 3.4. Subject to the provisions of Section 3.3,
Section 3.4, if applicable, and Section 3.5, the Trustee shall deliver and
redeliver any Security in permanent global form in the manner and upon
instructions given by the Person or Persons specified therein or in the
applicable Company Order. Any instructions by the Company with respect to
endorsement or delivery or redelivery of a Security in global form shall be in
writing but need not comply with Section 1.2 hereof and need not be accompanied
by an Officers' Certificate or an Opinion of Counsel.

                  The provisions of the last paragraph of Section 3.3 shall
apply to any Security in global form if such Security was never issued and sold
by the Company and the Company delivers to the Trustee the Security in global
form together with

                                       22
<PAGE>   31
written instructions (which need not comply with Section 1.2 hereof and need not
be accompanied by an Officers' Certificate or an Opinion of Counsel) with regard
to the reduction in the principal amount of Securities represented thereby,
together with the written statement contemplated by the last paragraph of
Section 3.3.

                  Notwithstanding the provisions of Section 2.1 and 3.7, unless
otherwise specified as contemplated by Section 3.1, payment of principal of,
premium, if any, and interest on any Registered Security in permanent global
form shall be made to the registered holder thereof.

                  Section 2.4. Form of Legend for Securities in Global Form. Any
Security in global form authenticated and delivered hereunder shall bear a
legend in substantially the following form or in such other form as may be
specified in accordance with Section 3.1:


                  "THIS SECURITY IS IN GLOBAL FORM WITHIN THE MEANING OF THE
         INDENTURE HEREINAFTER REFERRED TO AND IS REGISTERED IN THE NAME OF A
         DEPOSITARY OR A NOMINEE OF A DEPOSITARY. UNLESS AND UNTIL IT IS
         EXCHANGED IN WHOLE OR IN PART FOR SECURITIES IN CERTIFICATED FORM, THIS
         SECURITY MAY NOT BE TRANSFERRED EXCEPT AS A WHOLE BY THE DEPOSITARY TO
         A NOMINEE OF THE DEPOSITARY OR BY A NOMINEE OF THE DEPOSITARY TO THE
         DEPOSITARY OR ANOTHER NOMINEE OF THE DEPOSITARY OR BY THE DEPOSITARY OR
         ANY SUCH NOMINEE TO A SUCCESSOR DEPOSITARY OR A NOMINEE OF SUCH
         SUCCESSOR DEPOSITARY."

                  Section 3.1. Amount Unlimited; Issuable in Series. (a) The
aggregate principal amount of Securities which may be authenticated and

         with the marketing of Securities of the series.
    

                  (c) All Securities of any one series and interest coupons, if
any, appertaining thereto shall be substantially identical except as to
denomination and except as may otherwise be provided (i) by a Board Resolution,
(ii) by action taken pursuant to a Board Resolution and (subject to Section 3.3)
set forth, or determined in the manner provided, in the related Officers'

additional Securities of such series.

                  (d) If any of the terms of the Securities of any series are
established by action taken pursuant to a Board Resolution, a copy of such Board
Resolution shall be delivered to the Trustee at or prior to the delivery of the
Officers' Certificate setting forth, or providing the manner for determining,
the terms of the Securities of such series, and an appropriate record of any
action taken pursuant thereto in connection with the issuance of any Securities
of such series shall be delivered to the Trustee prior to the authentication and
delivery thereof.

   
          Section 3.2. Denominations. Unless otherwise provided as contemplated
by Section 3.1, any Registered Securities of a series denominated in Dollars
shall be issuable in denominations of U.S.$1,000 and any integral multiple

Securities denominated in a Foreign Currency shall be issuable in such
denominations as are established with respect to such Securities in or pursuant
to this Indenture. 
    

          Section 3.3. Execution, Authentication, Delivery and Dating.
Securities shall be executed on behalf of the Company by the Chairman of the
Board, the President, the Chief Executive Officer, the Chief Operating Officer,
the Chief Financial Officer or any Vice President of the Company, and need not

                                       28
<PAGE>   37
signatures of any of these officers on the Securities may be manual or
facsimile. The interest coupons, if any, of Bearer Securities shall bear the
facsimile signature of the Chairman of the Board, the President, the Chief
Executive Officer, the Chief Operating Officer, the Chief Financial Officer or
any Vice President of the Company, and need not be attested.

                  Securities and interest coupons bearing the manual or
facsimile signatures of individuals who were at any time Officers of the Company
shall bind the Company, notwithstanding that such individuals or any of them
have ceased to be Officers prior to the authentication and delivery of such
Securities or were not Officers at the date of such Securities.

                  At any time and from time to time, the Company may deliver
Securities, together with any interest coupons appertaining thereto, of any
series executed by the Company to the Trustee for authentication, together with
a Company Order for the authentication and delivery of such Securities, and the
Trustee in accordance with such Company Order shall authenticate and deliver
such Securities to or upon the order of the Company (as set forth in such
Company Order); provided, however, that, in the case of Securities of a series
offered in a Periodic Offering, the Trustee shall authenticate and deliver such
Securities from time to time in accordance with such other procedures
(including, without limitation, the receipt by the Trustee of oral or electronic
instructions from the Company or its duly authorized agents, promptly confirmed
in writing) acceptable to the Trustee as may be specified by or pursuant to a
Company Order delivered to the Trustee prior to the time of the first
authentication of Securities of such series.

                  If the form or terms of the Securities of a series have been
established by or pursuant to one or more Board Resolutions or one or more
indentures supplemental hereto as permitted by Sections 2.1 and 3.1, in
authenticating such Securities and accepting the additional responsibilities
under this Indenture in relation to such Securities, the Trustee shall be
entitled to receive, and (subject to section 315(a) through (d) of the Trust
Indenture Act) shall be fully protected in relying upon,

                  (i) an Opinion of Counsel stating:

                  (1) if the form or forms of such Securities and any interest
         coupons have been established by or pursuant to a Board Resolution as
         permitted by Section 2.1, that such forms have been established in
         conformity with the provisions of this Indenture;

                                       29
<PAGE>   38
                  (2) if the terms of such Securities and any interest coupons
         have been, or, in the case of Securities of a series offered in a
         Periodic Offering, will be, established by or pursuant to a Board
         Resolution as permitted by Section 3.1, that such terms have been, or,
         in the case of Securities of a series offered in a Periodic Offering,
         will be, established in conformity with the provisions of this
         Indenture, subject, in the case of Securities offered in a Periodic
         Offering, to any conditions specified in such Opinion of Counsel;

                  (3) if the form or terms of such Securities have been
         established in an indenture supplemental hereto, that such supplemental
         indenture has been duly authorized, executed and delivered by the
         Company and, when duly authorized, executed and delivered by the
         Trustee, will constitute a legal, valid and binding obligation
         enforceable against the Company in accordance with its terms, subject
         to (i) bankruptcy, insolvency, fraudulent transfer, reorganization,
         moratorium and other similar laws of general applicability relating to
         or affecting the enforcement of creditors' rights and to general
         principles of equity (regardless of whether enforcement is sought
         in a proceeding in equity or at law), and (ii) such other reasonable
         exceptions as may be specified in such Opinion of Counsel; and

                  (4) that such Securities, together with any interest coupons
         appertaining thereto, when issued by the Company and authenticated and
         delivered by the Trustee in the manner and subject to any conditions
         specified in such Opinion of Counsel, will constitute valid and legally
         binding obligations of the Company, enforceable against the Company in
         accordance with their terms, subject to (i) bankruptcy, insolvency,
         fraudulent transfer, reorganization, moratorium and other similar laws
         of general applicability relating to or affecting the enforcement of
         creditors' rights and to general equity principles (regardless of
         whether enforcement is sought in a proceeding in equity or at law) and
         except further as enforcement thereof may be limited by (A)
         requirements that a claim with respect to any Securities denominated
         other than in Dollars (or a Foreign Currency or currency unit judgment
         in respect of such claim) be converted into Dollars at a rate of
         exchange prevailing on a date determined pursuant to applicable law or
         (B) governmental authority to limit, delay or prohibit the making of
         payments in Foreign Currencies or currency units or payments outside
         the United States, and (ii) such other reasonable exceptions as may be
         specified in such Opinion of Counsel; and

                  (ii) an Officers' Certificate stating that all conditions
precedent provided for in this Indenture relating to the issuance of such
Securities have been

                                       30
<PAGE>   39
complied with and that, to the knowledge of the signers of such certificate, no
Event of Default with respect to such Securities shall have occurred and be
continuing.

                  Notwithstanding that such form or terms have been so
established, the Trustee shall have the right to decline to authenticate such
Securities if, in the opinion of the Trustee (after consultation with counsel),
the issue of such Securities pursuant to this Indenture will materially
adversely affect the Trustee's own rights, duties or immunities under this
Indenture or otherwise or if the Trustee determines that such authentication may
not lawfully be made.

                  Notwithstanding the provisions of Section 3.1 and of the two
preceding paragraphs, if all of the Securities of any series are not to be
issued at one time, it shall not be necessary to deliver the Officers'
Certificate otherwise required pursuant to Section 3.1 or the Company Order and
Opinion of Counsel otherwise required pursuant to the two preceding paragraphs
in connection with the authentication of each Security of such series if such
documents, with appropriate modifications to cover such future issuances, are
delivered at or prior to the authentication upon original issuance of the first
Security of such series to be issued.

                  With respect to Securities of a series offered in a Periodic
Offering, the Trustee may rely, as to the authorization by the Company of any of
such Securities, the form and terms thereof and the legality, validity, binding
effect and enforceability thereof, upon the Opinion of Counsel and the other
documents delivered pursuant to Sections 2.1 and 3.1 and this Section, as
applicable, in connection with the first authentication of Securities of such
series.

                  If the Company shall establish pursuant to Section 3.1 that
the Securities of a series are to be issued in whole or in part in global form,
then the Company shall execute and the Trustee shall, in accordance with this
Section and the Company Order with respect to such series, authenticate and
deliver one or more Securities in global form that (i) shall represent and shall
be denominated in an amount equal to the aggregate principal amount of the
Outstanding Securities of such series to be represented by such Security or
Securities in global form, (ii) shall be registered, if a Registered Security,
in the name of the Depositary for such Security or Securities in global form or
the nominee of such Depositary, (iii) shall be delivered by the Trustee to such
Depositary or pursuant to such Depositary's instruction and (iv) shall bear the
legend set forth in Section 2.4.

                                       31
<PAGE>   40
                  Each Depositary designated pursuant to Section 3.1 for a
Registered Security in global form must, at the time of its designation and at
all times while it serves as Depositary, be a clearing agency registered under
the Securities Exchange Act of 1934 and any other applicable statute or
regulation. If requested by the Company, the Trustee shall enter into an
agreement with a Depositary governing the respective duties and rights of such
Depositary and the Trustee with regard to Securities issued in global form.

                  Each Registered Security shall be dated the date of its
authentication and each Bearer Security shall be dated as of the date specified
pursuant to Section 3.1.

                  No Security or interest coupon appertaining thereto shall be
entitled to any benefits under this Indenture or be valid or obligatory for any
purpose until authenticated by the manual signature of one of the authorized
signatories of the Trustee or an Authenticating Agent and no interest coupon
shall be valid until the Security to which it appertains has been so
authenticated. Such signature upon any Security shall be conclusive evidence,
and the only evidence, that such Security has been duly authenticated and
delivered under this Indenture and is entitled to the benefits of this
Indenture. Except as permitted by Section 3.6 or 3.7, the Trustee shall not
authenticate and deliver any Bearer Security unless all appurtenant interest
coupons for interest then matured have been detached and cancelled.

                  Notwithstanding the foregoing, if any Security shall have been
authenticated and delivered hereunder but never issued and sold by the Company,
and the Company shall deliver such Security to the Trustee for cancellation as
provided in Section 3.9 together with a written statement (which need not comply
with Section 1.2 hereof and need not be accompanied by an Officers' Certificate
or an Opinion of Counsel) stating that such Security has never been issued and
sold by the Company, for all purposes of this Indenture such Security shall be
deemed never to have been authenticated and delivered hereunder and shall not be
entitled to the benefits of this Indenture.

                  Section 3.4. Temporary Securities. Pending the preparation of
definitive Securities of any series, the Company may execute and, upon Company
Order, the Trustee shall authenticate and deliver temporary Securities of such
series which are printed, lithographed, typewritten, mimeographed or otherwise
produced, in any authorized denomination, substantially of the tenor and form,
with or without interest coupons, of the definitive Securities in lieu of which
they are issued and with such appropriate insertions, omissions, substitutions
and other

                                       32
<PAGE>   41
variations as the officers executing such Securities may determine, as
conclusively evidenced by their execution of such Securities and interest
coupons, if any. In the case of Securities of any series, such temporary
Securities may be in global form, representing all or a portion of the
Outstanding Securities of such series.

                  Except in the case of temporary Securities in global form,
each of which shall be exchanged in accordance with the provisions thereof, if
temporary Securities of any series are issued, the Company will cause definitive
Securities of such series to be prepared without unreasonable delay. After
preparation of definitive Securities of such series, the temporary Securities of
such series shall be exchangeable for definitive Securities of such series upon
surrender of the temporary Securities of such series at the office or agency of
the Company pursuant to Section 9.2 in a Place of Payment for such series,
without charge to the Holder. Upon surrender for cancellation of any one or more
temporary Securities of any series (accompanied by any unmatured interest
coupons appertaining thereto), the Company shall execute and the Trustee shall
authenticate and deliver in exchange therefor a like principal amount of
definitive Securities of the same series of authorized denominations and of like
tenor; provided, however, that no definitive Bearer Security shall be delivered
in exchange for a temporary Registered Security; and provided, further, that no
definitive Bearer Security shall be delivered in exchange for a temporary Bearer
Security unless such delivery shall occur only outside the United States. Until
so exchanged, the temporary Securities of any series shall in all respects be
entitled to the same benefits under this Indenture as definitive Securities of
such series except as otherwise specified as contemplated by Section 3.1.

                  Section 3.5. Registration, Transfer and Exchange. The Company
shall cause to be kept at the Corporate Trust Office of the Trustee or in any
office or agency to be maintained by the Company in accordance with Section 9.2
in a Place of Payment a register (the "Register") in which, subject to such
reasonable regulations as it may prescribe, the Company shall provide for the
registration of Registered Securities and the registration of transfers of
Registered Securities. The Register shall be in written form or any other form
capable of being converted into written form within a reasonable time. The
Trustee is hereby initially appointed "Registrar" for the purpose of registering
Registered Securities and transfers of Registered Securities as herein provided.

                  Upon surrender for registration of transfer of any Registered
Security of any series at the office or agency maintained pursuant to Section
9.2 in a Place of Payment for that series, the Company shall execute, and the
Trustee shall authenticate and deliver, in the name of the designated transferee
or transferees,

                                       33
<PAGE>   42
one or more new Registered Securities of the same series, of any authorized
denominations and of a like aggregate principal amount and tenor and containing
identical terms and provisions.

                  Bearer Securities (except for any temporary global Bearer
Securities) or any interest coupons appertaining thereto (except for interest
coupons attached to any temporary global Bearer Security) shall be transferable
by delivery.

                  At the option of the Holder, Registered Securities of any
series (except a Registered Security in global form) may be exchanged for other
Registered Securities of the same series, of any authorized denominations, of a
like aggregate principal amount and tenor and containing identical terms and
provisions, upon surrender of the Registered Securities to be exchanged at such
office or agency. Whenever any Registered Securities are so surrendered for
exchange, the Company shall execute, and the Trustee shall authenticate and
deliver, the Registered Securities which the Holder making the exchange is
entitled to receive. Unless otherwise specified as contemplated by Section 3.1,
Bearer Securities may not be issued in exchange for Registered Securities.

                  Unless otherwise specified as contemplated by Section 3.1, at
the option of the Holder, Bearer Securities of such series may be exchanged for
Registered Securities (if the Securities of such series are issuable in
registered form) or Bearer Securities (if Bearer Securities of such series are
issuable in more than one denomination and such exchanges are permitted by such
series) of the same series, of any authorized denominations, of like aggregate
principal amount and tenor and containing identical terms and conditions, upon
surrender of the Bearer Securities to be exchanged at any such office or agency,
with all unmatured interest coupons and all matured interest coupons in default
thereto appertaining. If the Holder of a Bearer Security is unable to produce
any such unmatured interest coupon or coupons or matured interest coupon or
coupons in default, such exchange may be effected if the Bearer Securities are
accompanied by payment in funds acceptable to the Company and the Trustee in an
amount equal to the face amount of such missing interest coupon or coupons, or
the surrender of such missing interest coupon or interest coupons may be waived
by the Company and the Trustee if there be furnished to them such security or
indemnity as they may require to save each of them and any Paying Agent
harmless. If thereafter the Holder of such Security shall surrender to any
Paying Agent any such missing interest coupon in respect of which such a payment
shall have been made, such Holder shall be entitled to receive the amount of
such payment; provided, however, that, except as otherwise provided in Section
9.2, interest represented by interest coupons shall be payable only upon
presentation and surrender of those

                                       34
<PAGE>   43
interest coupons at an office or agency located outside the United States.
Notwithstanding the foregoing, in case any Bearer Security of any series is
surrendered at any such office or agency in exchange for a Registered Security
of the same series after the close of business at such office or agency on (i)
any Regular Record Date and before the opening of business at such office or
agency on the relevant Interest Payment Date, or (ii) any Special Record Date
and before the opening of business at such office or agency on the related date
for payment of Defaulted Interest, such Bearer Security shall be surrendered
without the interest coupon relating to such Interest Payment Date or proposed
date of payment, as the case may be (or, if such interest coupon is so
surrendered with such Bearer Security, such interest coupon shall be returned to
the Person so surrendering the Bearer Security), and interest or Defaulted
Interest, as the case may be, will not be payable on such Interest Payment Date
or proposed date for payment, as the case may be, in respect of the Registered
Security issued in exchange for such Bearer Security, but will be payable only
to the Holder of such interest coupon, when due in accordance with the
provisions of this Indenture.

                  Notwithstanding anything herein to the contrary, the exchange
of Bearer Securities for Registered Securities shall be subject to applicable
laws and regulations in effect at the time of exchange. Neither the Company, the
Trustee nor the Registrar shall exchange any Bearer Securities for Registered
Securities if it has received an Opinion of Counsel that as a result of such
exchange the Company would suffer adverse consequences under the United States
Federal income tax laws and regulations then in effect and the Company has
delivered to the Trustee a Company Order directing the Trustee not to make such
exchanges thereafter, unless and until the Trustee receives a subsequent Company
Order to the contrary. The Company shall deliver copies of such Company Order to
the Registrar.

                  Notwithstanding any other provision of this Section, unless
and until it is exchanged in whole or in part for Securities in certificated
form, a Security in global form representing all or a portion of the Securities
of a series may not be transferred except as a whole by the Depositary for such
series to a nominee of such Depositary or by a nominee of such Depositary to
such Depositary or another nominee of such Depositary or by such Depositary or
any such nominee to a successor Depositary for such series or a nominee of such
successor Depositary.

                  If at any time the Depositary for the Securities of a series
notifies the Company that it is unwilling or unable to continue as Depositary
for the Securities of such series or if at any time the Depositary for the
Securities of such series shall no longer be eligible under Section 3.3, the
Company shall appoint a successor

                                       35
<PAGE>   44
Depositary with respect to the Securities of such series. If a successor
Depositary for the Securities of such series is not appointed by the Company
prior to the resignation of the Depositary and, in any event, within 90 days
after the Company receives such notice or becomes aware of such ineligibility,
the Company's designation of the Depositary pursuant to Section 3.1(b)(23) shall
no longer be effective with respect to the Securities of such series and the
Company shall execute, and the Trustee, upon receipt of a Company Order for the
authentication and delivery of certificated Securities of such series of like
tenor, shall authenticate and deliver, Securities of such series of like tenor
in certificated form, in authorized denominations and in an aggregate principal
amount equal to the principal amount of the Security or Securities of such
series of like tenor in global form in exchange for such Security or Securities
in global form.

                  The Company may at any time in its sole discretion determine
that Securities issued in global form shall no longer be represented by such a
Security or Securities in global form. In such event the Company shall execute,
and the Trustee, upon receipt of a Company Order for the authentication and
delivery of certificated Securities of such series of like tenor, shall
authenticate and deliver, Securities of such series of like tenor in
certificated form, in authorized denominations and in an aggregate principal
amount equal to the principal amount of the Security or Securities of such
series of like tenor in global form in exchange for such Security or Securities
in global form.

                  If specified by the Company pursuant to Section 3.1 with
respect to a series of Securities, the Depositary for such series may surrender
a Security in global form of such series in exchange in whole or in part for
Securities of such series in certificated form on such terms as are acceptable
to the Company and such Depositary. Thereupon, the Company shall execute, and
the Trustee shall authenticate and deliver, without service charge,

                  (i) to each Person specified by such Depositary a new
certificated Security or Securities of the same series of like tenor, of any
authorized denomination as requested by such Person in aggregate principal
amount equal to and in exchange for such Person's beneficial interest in the
Security in global form; and

                  (ii) to such Depositary a new Security in global form of like
tenor in a denomination equal to the difference, if any, between the principal
amount of the surrendered Security in global form and the aggregate principal
amount of certificated Securities delivered to Holders thereof.

                                       36
<PAGE>   45
                  Upon the exchange of a Security in global form for Securities
in certificated form, such Security in global form shall be cancelled by the
Trustee. Unless expressly provided with respect to the Securities of any series
that such Security may be exchanged for Bearer Securities, Securities in
certificated form issued in exchange for a Security in global form pursuant to
this Section shall be registered in such names and in such authorized
denominations as the Depositary for such Security in global form, pursuant to
instructions from its direct or indirect participants or otherwise, shall
instruct the Trustee in writing. The Trustee shall deliver such Securities to
the Persons in whose names such Securities are so registered.

                  Whenever any Securities are surrendered for exchange, the
Company shall execute, and the Trustee shall authenticate and deliver, the
Securities which the Holder making the exchange is entitled to receive.

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

                  Every Registered Security presented or surrendered for
registration of transfer or for exchange shall (if so required by the Company,
the Registrar or the Trustee) be duly endorsed, or be accompanied by a written
instrument of transfer in form satisfactory to the Company, the Registrar and
the Trustee 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 for any exchange of Securities, 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 or transfer or exchange of
Securities, other than exchanges pursuant to Section 3.4 or 11.7 not involving
any transfer.

                  The Company shall not be required (i) to issue, register the
transfer of, or exchange any Securities for a period beginning at the opening of
business 15 days before any selection for redemption of Securities of like tenor
and of the series of which such Security is a part and ending at the close of
business on the earliest date on which the relevant notice of redemption is
deemed to have been given to all Holders of Securities of like tenor and of such
series to be redeemed; (ii) to register the transfer of or exchange any
Registered Security so selected for redemption, in whole or in part, except the
unredeemed portion of any Security being redeemed in part; or (iii) to exchange
any Bearer Security so selected for

                                       37
<PAGE>   46
redemption, except that such a Bearer Security may be exchanged for a Registered
Security of that series and like tenor; provided that such Registered Security
shall be simultaneously surrendered for redemption.

                  The foregoing provisions relating to registration, transfer
and exchange may be modified, supplemented or superseded with respect to any
series of Securities by a Board Resolution or in one or more indentures
supplemental hereto.

                  Section 3.6. Replacement Securities. If a mutilated Security
or a Security with a mutilated interest coupon appertaining to it is surrendered
to the Trustee, together with, in proper cases, such security or indemnity as
may be required by the Company or the Trustee to save each of them harmless, the
Company shall execute and the Trustee shall authenticate and deliver a
replacement Registered Security, if such surrendered Security was a Registered
Security, or a replacement Bearer Security with interest coupons corresponding
to the interest coupons appertaining to the surrendered Security, if such
surrendered Security was a Bearer Security, of the same series and date of
maturity.

                  If there shall be delivered to the Company and the Trustee (i)
evidence to their satisfaction of the destruction, loss or theft of any Security
or Security with a destroyed, lost or stolen interest coupon and (ii) such
security 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 Security or interest coupon has been acquired by a bona
fide purchaser, the Company shall execute and the Trustee shall authenticate and
deliver in lieu of any such destroyed, lost or stolen Security or in exchange
for the Security to which a destroyed, lost or stolen interest coupon appertains
(with all appurtenant interest coupons not destroyed, lost or stolen), a
replacement Registered Security, if such Holder's claim appertains to a
Registered Security, or a replacement Bearer Security with interest coupons
corresponding to the interest coupons appertaining to the destroyed, lost or
stolen Bearer Security or the Bearer Security to which such lost, destroyed or
stolen interest coupon appertains, if such Holder's claim appertains to a Bearer
Security, of the same series and principal amount, containing identical terms
and provisions and bearing a number not contemporaneously outstanding with
interest coupons corresponding to the interest coupons, if any, appertaining to
the destroyed, lost or stolen Security.

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

                                       38
<PAGE>   47
Security or interest coupon; provided, however, that payment of principal of and
any premium or interest on Bearer Securities shall, except as otherwise provided
in Section 9.2, be payable only at an office or agency located outside the
United States and, unless otherwise specified as contemplated by Section 3.1,
any interest on Bearer Securities shall be payable only upon presentation and
surrender of the interest coupons appertaining thereto.

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

                  Every new Security of any series with its interest coupons, if
any, issued pursuant to this Section in lieu of any destroyed, lost or stolen
Security, or in exchange for a Security to which a destroyed, lost or stolen
interest coupon appertains, shall constitute an original additional contractual
obligation of the Company, whether or not the destroyed, lost or stolen Security
and its interest coupon, if any, or the destroyed, lost or stolen interest
coupon, 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 Securities of that series and their interest coupons, if any, 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 Securities or
interest coupons.

                  Section 3.7. Payment of Interest; Interest Rights Preserved.
(a) Unless otherwise provided as contemplated by Section 3.1, interest, if any,
on any Registered Security which is payable, and is punctually paid or duly
provided for, on any Interest Payment Date shall be paid to the Person in whose
name that Security (or one or more Predecessor Securities) is registered at the
close of business on the Regular Record Date for such interest at the office or
agency maintained for such purpose pursuant to Section 9.2; provided, however,
that at the option of the Company, interest on any series of Registered
Securities that bear interest may be paid (i) by check mailed to the address of
the Person entitled thereto as it shall appear on the Register of Holders of
Securities of such series or (ii) at the expense of the Company, by wire
transfer to an account maintained by the Person entitled thereto as specified in
the Register of Holders of Securities of such series.

                                       39
<PAGE>   48
                  Unless otherwise provided as contemplated by Section 3.1, (i)
interest, if any, on Bearer Securities shall be paid only against presentation
and surrender of the interest coupons for such interest installments as are
evidenced thereby as they mature and (ii) original issue discount, if any, on
Bearer Securities shall be paid only against presentation and surrender of such
Securities; in either case at the office of a Paying Agent located outside the
United States, unless the Company shall have otherwise instructed the Trustee in
writing, provided that any such instruction for payment in the United States
does not cause any Bearer Security to be treated as a "registration-required
obligation" under United States laws and regulations. The interest, if any, on
any temporary Bearer Security shall be paid, as to any installment of interest
evidenced by an interest coupon attached thereto only upon presentation and
surrender of such interest coupon and, as to other installments of interest,
only upon presentation of such Security for notation thereon of the payment of
such interest. If at the time a payment of principal of or interest, if any, on
a Bearer Security or interest coupon shall become due, the payment of the full
amount so payable at the office or offices of all the Paying Agents outside the
United States is illegal or effectively precluded because of the imposition of
exchange controls or other similar restrictions on the payment of such amount in
Dollars, then the Company may instruct the Trustee in writing to make such
payments at a Paying Agent located in the United States, provided that provision
for such payment in the United States would not cause such Bearer Security to be
treated as a "registration-required obligation" under United States laws and
regulations.

                  (b) Unless otherwise provided as contemplated by Section 3.1,
any interest on Securities of any series which is payable, but is not punctually
paid or duly provided for, on any Interest Payment Date in the case of
Registered Securities and upon presentation and surrender of the applicable
interest coupon in accordance with the second paragraph of Section 3.7(a) in the
case of Bearer Securities (herein called "Defaulted Interest"), shall forthwith
cease to be payable to the Holders on the relevant Regular Record Date by virtue
of their having been such Holders, and such Defaulted Interest may be paid by
the Company, at its election in each case, as provided in clause (1) or (2)
below:

                  (1) In the case of Registered Securities, the Company may
         elect to make payment of such Defaulted Interest to the Persons in
         whose names such Registered Securities (or their respective Predecessor
         Securities) are registered at the close of business on a Special Record
         Date for the payment of such Defaulted Interest, which shall be fixed
         in the following manner. The Company shall notify the Trustee in
         writing of the amount of Defaulted Interest proposed to be paid on each
         such Registered Security and the date




                                       40
<PAGE>   49
         of the proposed payment, and shall deposit with the Trustee an amount
         of money equal to the aggregate amount proposed to be paid in respect
         of such Defaulted Interest or shall make arrangements satisfactory to
         the Trustee for such deposit prior to the date of the proposed payment,
         such money when deposited to be held in trust for the benefit of the
         Persons entitled to such Defaulted Interest as in this clause (1)
         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 of such Registered Securities at his or
         her address as it appears in the 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 such Registered Securities (or their respective Predecessor
         Securities) are registered at the close of business on such Special
         Record Date and shall no longer be payable pursuant to the following
         clause (2).

                  (2)(x) In the case of Registered Securities, the Company may
         make payment of such Defaulted Interest to the Persons in whose names
         such Registered Securities (or their respective Predecessor Securities)
         are registered at the close of business on a specified date in any
         other lawful manner not inconsistent with the requirements of any
         securities exchange on which such Registered Securities may be listed,
         and upon such notice as may be required by such exchange, if, after
         notice given by the Company to the Trustee of the proposed payment
         pursuant to this clause (2)(x), such manner of payment shall be deemed
         practicable by the Trustee; or (y) unless otherwise provided as
         contemplated by Section 3.1, in the case of Bearer Securities, the
         Company may make payment of Defaulted Interest on such Bearer
         Securities in any lawful manner not inconsistent with the requirements
         of any securities exchange on which such Bearer Securities may be
         listed, and upon such notice as may be required by such exchange, if,
         after notice given by the Company to the Trustee of the proposed
         payment pursuant to this clause (2)(y), such manner of payment shall be
         deemed practicable by the Trustee.

                                       41
<PAGE>   50
                  (c) Subject to the foregoing provisions of this Section and
Section 3.5, each Security delivered under this Indenture upon registration of
transfer of or in exchange for or in lieu of any other Security shall carry the
rights to interest accrued and unpaid, and to accrue, which were carried by such
other Security.

                  (d) Subject to the provisions of Section 14.2, in the case of
any Registered Security which is converted or exchanged after any Regular Record
Date and on or prior to the next succeeding Interest Payment Date (other than
any Security the principal of (or premium, if any, on) which shall become due
and payable, whether at a Stated Maturity or by declaration of acceleration,
call for redemption, or otherwise, 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 or exchange and
such interest (whether or not punctually paid or duly provided for) shall be
paid to the Person in whose name that Registered Security (or any one or more
Predecessor Securities) is registered at the close of business on such Regular
Record Date. Except as otherwise expressly provided in the immediately preceding
sentence, in the case of any Security which is converted or exchanged, interest
whose Stated Maturity is after the date of conversion or exchange of such
Security shall not be payable.

                  Section 3.8. Persons Deemed Owners. Unless otherwise provided
as contemplated by Section 3.1, prior to due presentment of any Registered
Security 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 Registered
Security is registered as the owner of such Registered Security for the purpose
of receiving payment of principal of, premium, if any, and (subject to Section
3.7) interest on such Registered Security and for all other purposes whatsoever,
whether or not such Registered Security be overdue, and neither the Company, the
Trustee nor any agent of the Company or the Trustee shall be affected by notice
to the contrary.

                  Unless otherwise provided as contemplated by Section 3.1, the
Company, the Trustee and any agent of the Company or the Trustee may treat the
bearer of any Bearer Security and the bearer of any interest coupon as the
absolute owner of such Bearer Security or interest coupon for the purpose of
receiving payment thereof or on account thereof and for all other purposes
whatsoever, whether or not such Bearer Security or interest coupon 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.

                                       42
<PAGE>   51
            None of the Company, the Trustee or any agent of the Company or the
Trustee shall have any responsibility or liability for any aspect of the records
relating to or payments made on account of beneficial ownership interests of a
Security in global form, or for maintaining, supervising or reviewing any
records relating to such beneficial ownership interests. No holder of any
beneficial interest in any Security in global form, held on its behalf by or
through a Depositary, shall have any rights under this Indenture with respect to
such Security in global form, and such Depositary may be treated by the Company,
the Trustee and any agent of the Company or the Trustee as the owner of such
Security in global form for all purposes whatsoever. With respect to any
Security in global form, nothing herein shall prevent the Company or the
Trustee, or any agent of the Company or the Trustee, from giving effect to any
written certification, proxy or other authorization furnished by any Depositary
(or its nominee), as a Holder, with respect to such Security in global form or
impair, as between such Depositary and owners of beneficial interests in such
Security in global form, the operation of customary practices governing the
exercise of the rights of such Depositary (or its nominee) as Holder of such
Security in global form.

            Section 3.9. Cancellation. All Securities and interest coupons
appertaining thereto, if any, surrendered for payment, redemption, conversion,
registration of transfer or exchange or for credit against any sinking fund
payment 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 Securities, together with
interest coupons appertaining thereto, if any, previously authenticated and
delivered hereunder which the Company may have acquired in any manner
whatsoever, and may deliver to the Trustee (or to any other Person for delivery
to the Trustee) for cancellation any Securities, together with interest coupons
appertaining thereto, if any, previously authenticated hereunder which the
Company has not issued and sold, and all Securities and interest coupons so
delivered shall be promptly cancelled by the Trustee. No Securities shall be
authenticated in lieu of or in exchange for any Securities cancelled as provided
in this Section 3.9, except as expressly permitted by this Indenture. All
cancelled Securities and interest coupons held by the Trustee shall be disposed
of in accordance with its customary procedures, and the Trustee shall thereafter
deliver to the Company a certificate with respect to such disposition.

            Section 3.10. Computation of Interest. Except as otherwise specified
as contemplated by Section 3.1, interest on the Securities of each series shall
be computed on the basis of a 360-day year of twelve 30-day months.

            Section 3.11. CUSIP Numbers. The Company in issuing the Securities
may use "CUSIP" numbers (if then generally in use and in addition to the other
identification numbers printed on the Securities), and, in such case, the
Trustee shall use "CUSIP" numbers in notices of redemption as a convenience to

<PAGE>   54
                  (3) the Company has delivered to the Trustee an Officers'
         Certificate and an Opinion of Counsel, each stating that all conditions
         precedent herein provided for relating to the satisfaction and
         discharge of this Indenture as to such series have been complied with.

                  Notwithstanding the satisfaction and discharge of this
Indenture, the obligation of the Company to the Trustee and any predecessor
Trustee under Section 6.7, the obligations of the Company to any Authenticating
Agent under Section 6.13 and, if money shall have been deposited with the
Trustee pursuant to subclause (B) of clause (1) of this Section, the obligations
of the Trustee under Section 4.2, Section 9.2, the last paragraph of Section 9.3
and Section 10.1 shall survive.

                  Section 4.2. Application of Trust Funds. Subject to the
provisions of the last paragraph of Section 9.3, all money deposited with the
Trustee pursuant to Section 4.1 shall be held in trust and applied by it, in
accordance with the provisions of the Securities, the interest coupons
appertaining thereto, if any, and this Indenture, to the payment, either
directly or through any Paying Agent (including the Company acting as its own
Paying Agent) as the Trustee may determine, to the Persons entitled thereto, of
the principal, premium, if any and any interest for whose payment such money has
been deposited with or received by the Trustee, but such money need not be
segregated from other funds except as otherwise provided herein and except to
the extent required by law.

                  Section 4.3. Applicability of Defeasance Provisions; Company's
Option to Effect Defeasance or Covenant Defeasance. Except as otherwise
specified as contemplated by Section 3.1 for the Securities of any series, the
provisions of Sections 4.3 through 4.9 inclusive, with such modifications
thereto as may be specified pursuant to Section 3.1 with respect to any series
of Securities, shall be applicable to the Securities and any interest coupons
appertaining thereto.

                  Section 4.4. Defeasance and Discharge. On and after the date
on which the conditions set forth in Section 4.6 are satisfied with respect to
the Securities of or within any series, the Company shall be deemed to have paid
and been discharged from its obligations with respect to such Securities and any
interest coupons appertaining thereto (hereinafter "defeasance"). For this
purpose, such defeasance means that the Company shall be deemed to have paid and
discharged the entire indebtedness represented by such Securities and any
interest coupons appertaining thereto which shall thereafter be deemed to be
"Outstanding" only for the purposes of Section 4.7 and the other Sections of
this Indenture referred to in clause (ii) of this Section, and to have satisfied
all its other


                                       46
<PAGE>   55
obligations under such Securities and any interest coupons appertaining thereto
and this Indenture insofar as such Securities and any interest coupons
appertaining thereto are concerned (and the Trustee, upon payment of all amounts
due it under Section 6.7, at the expense of the Company, shall on a Company
Order execute proper instruments acknowledging the same), except the following
which shall survive until otherwise terminated or discharged hereunder: (i) the
rights of Holders of such Securities and any interest coupons appertaining
thereto to receive, solely from the trust funds described in Section 4.6(a) and
as more fully set forth in such Section, payments in respect of the principal
of, premium, if any, and interest, if any, on such Securities or any interest
coupons appertaining thereto when such payments are due; (ii) the Company's
obligations with respect to such Securities under Sections 3.5, 3.6, 9.2 and 9.3
and with respect to the payment of additional amounts, if any, payable with
respect to such Securities as specified pursuant to Section 3.1(b)(16); (iii)
the Company's obligations with respect to a conversion or exchange of such
Securities; (iv) the rights, powers, trusts, duties and immunities of the
Trustee hereunder and (v) this Article 4. Subject to compliance with this
Article 4, the Company may defease the Securities of any series and any interest
coupons appertaining thereto under this Section 4.4 notwithstanding a prior
covenant defeasance (as defined herein) under Section 4.5 with respect to such
Securities and any interest coupons appertaining thereto. Following a
defeasance, payment of such Securities may not be accelerated because of an
Event of Default.

                  Section 4.5. Covenant Defeasance. On and after the date on
which the conditions set forth in Section 4.6 (other than Section 4.6(c)) are
satisfied with respect to the Securities of or within any series, (i) the
Company shall be released from its obligations under Sections 7.1 and 9.4 and,
if specified pursuant to Section 3.1, its obligations under any other covenant,
with respect to such Securities and any interest coupons appertaining thereto
and (ii) the occurrence of any event specified in Sections 5.1(3) or 5.1(7)
(with respect to any of the obligations described in clause (i) above) or 5.1(4)
shall be deemed not to be or result in a Default or Event of Default
(hereinafter, "covenant defeasance"), and such Securities and any interest
coupons appertaining thereto shall thereafter be deemed to be not "Outstanding"
for the purposes of any request, demand, authorization, direction, notice,
waiver, consent or declaration or Act of Holders (and the consequences of any
thereof) in connection with Section 7.1, or 9.4, such other covenant specified
pursuant to Section 3.1, or Section 5.1(4), but shall continue to be deemed
"Outstanding" for all other purposes hereunder. For this purpose, such covenant
defeasance means that, with respect to such Securities and any interest coupons
appertaining thereto, the Company may omit to comply with and shall have no
liability in respect of any term, condition or limitation set forth


                                       47
<PAGE>   56
in any such Section or such other covenant, whether directly or indirectly, by
reason of any reference elsewhere herein to any such Section or such other
covenant or by reason of reference in any such Section or such other covenant to
any other provision herein or in any other document and such omission to comply
shall not constitute a Default or an Event of Default under Section 5.1(3),
5.1(4) or 5.1(7) or otherwise, as the case may be, but, except as specified
above, the remainder of this Indenture and such Securities and any interest
coupons appertaining thereto shall be unaffected thereby.

                  Section 4.6. Conditions to Defeasance or Covenant Defeasance.
The following shall be the conditions to application of Section 4.4 or Section
4.5 to any Securities of or within a series and any interest coupons
appertaining thereto:

                  (a) The Company shall have deposited or caused to be deposited
         irrevocably with the Trustee (or another trustee satisfying the
         requirements of Section 6.9 who shall agree to comply with, and shall
         be entitled to the benefits of, the provisions of Sections 4.3 through
         4.9 inclusive and the last paragraph of Section 9.3 applicable to the
         Trustee, for purposes of such Sections also a "Trustee") as trust funds
         in trust for the purpose of making the payments referred to in clauses
         (x) and (y) of this Section 4.6(a), specifically pledged as security
         for, and dedicated solely to, the benefit of the Holders of such
         Securities and any interest coupons appertaining thereto, with written
         instructions to the Trustee as to the application thereof, (A) money in
         an amount (in such currency, currencies or currency unit or units in
         which such Securities and any interest coupons appertaining thereto are
         then specified as payable at Maturity), or (B) if Securities of such
         series are not subject to repayment at the option of Holders,
         Government Obligations which through the payment of interest and
         principal in respect thereof in accordance with their terms will
         provide, not later than one day before the due date of any payment
         referred to in clause (x) or (y) of this Section 4.6(a), money in an
         amount or (C) a combination thereof in an amount, sufficient, in the
         opinion of a nationally recognized firm of independent certified public
         accountants or a nationally recognized investment banking firm
         expressed in a written certification thereof delivered to the Trustee,
         to pay and discharge, and which shall be applied by the Trustee to pay
         and discharge, (x) the principal of, premium, if any, and interest, if
         any, on such Securities and any interest coupons appertaining thereto
         on the Maturity of such principal or installment of principal or
         interest and (y) any mandatory sinking fund payments applicable to such
         Securities on the day on which such payments are due and payable in
         accordance with the terms of this Indenture and such



                                       48
<PAGE>   57
         Securities and any interest coupons appertaining thereto. Before such a
         deposit the Company may make arrangements satisfactory to the Trustee
         for the redemption of Securities at a future date or dates in
         accordance with Article 11 which shall be given effect in applying the
         foregoing.

                  (b) No Default or Event of Default with respect to the
         Securities of that series shall have occurred or be continuing on the
         date of such a deposit or shall occur as a result of such a deposit or,
         insofar as Sections 5.1(5) and (6) are concerned, shall occur at any
         time during the period ending on the 91st day after the date of such
         deposit (it being understood that this condition shall not be deemed
         satisfied until the expiration of such period).

                  (c) In the case of an election under Section 4.4, the Company
         shall have delivered to the Trustee an Officers' Certificate and an
         Opinion of Counsel to the effect that (i) the Company has received
         from, or there has been published by, the Internal Revenue Service a
         ruling, or (ii) since the date of execution of this Indenture, there
         has been a change in the applicable U.S. Federal income tax law, in
         either case to the effect that, and based thereon such opinion shall
         confirm that, the Holders of such Securities and any interest coupons
         appertaining thereto will not recognize income, gain or loss for U.S.
         Federal income tax purposes as a result of such defeasance and will be
         subject to U.S. Federal income tax on the same amount and in the same
         manner and at the same times, as would have been the case if such
         deposit, defeasance and discharge had not occurred.

                  (d) In the case of an election under Section 4.5, the Company
         shall have delivered to the Trustee an Officers' Certificate and an
         Opinion of Counsel to the effect that the Holders of such Securities
         and any interest coupons appertaining thereto will not recognize
         income, gain or loss for U.S. Federal income tax purposes as a result
         of such covenant defeasance and will be subject to U.S. Federal income
         tax on the same amount and in the same manner and at the same times, as
         would have been the case if such deposit and covenant defeasance had
         not occurred.

                  (e) The Company shall have delivered to the Trustee an
         Officers' Certificate and an Opinion of Counsel, each stating that all
         conditions precedent to the defeasance under Section 4.4 or the
         covenant defeasance under Section 4.5 (as the case may be) have been
         complied with.


                                       49
<PAGE>   58
                  (f) Such defeasance or covenant defeasance shall be effected
         in compliance with any additional or substitute terms, conditions or
         limitations which may be imposed on the Company in connection therewith
         as contemplated by Section 3.1.

                  (g) At the time of such deposit: (A) no Default in the payment
         of principal of (or premium, if any) or interest on any Senior Debt
         shall have occurred and be continuing or (B) no other Event of Default
         with respect to any Senior Debt shall have occurred and be continuing
         and shall have resulted in such Senior Debt becoming or being declared
         due and payable prior to the date on which it would otherwise have
         become due and payable, or, in the case of either clause (A) or clause
         (B) above, each such Default or Event of Default shall have been cured
         or waived or shall have ceased to exist.

                  Section 4.7. Deposited Money and Government Obligations to Be
Held in Trust. Subject to the provisions of the last paragraph of Section 9.3,
all money and Government Obligations (or other property as may be provided
pursuant to Section 3.1) (including the proceeds thereof) deposited with the
Trustee pursuant to Section 4.6 in respect of any Securities of any series and
any interest coupons appertaining thereto shall be held in trust and applied by
the Trustee, in accordance with the provisions of such Securities and any
interest coupons appertaining thereto and this Indenture, to the payment, either
directly or through any Paying Agent (including the Company acting as its own
Paying Agent) as the Trustee may determine, to the Holders of such Securities
and any interest coupons appertaining thereto of all sums due and to become due
thereon in respect of principal, premium, if any, and interest, if any, but such
money need not be segregated from other funds except as provided herein and
except to the extent required by law.

                  Section 4.8. Repayment to Company. The Trustee (and any Paying
Agent) shall promptly pay to the Company upon Company Request any excess money
or securities held by them at any time.

                  The provisions of the last paragraph of Section 9.3 shall
apply to any money or securities held by the Trustee or any Paying Agent under
this Article 4 that remain unclaimed for two years after the Maturity of any
series of Securities for which money or securities have been deposited pursuant
to Section 4.6(a).

                  Section 4.9. Indemnity for Government Obligations. The Company
shall pay, and shall indemnify the Trustee against, any tax, fee or other


                                       50
<PAGE>   59
charge imposed on or assessed against Government Obligations deposited pursuant
to this Article or the principal and interest and any other amount received on
such Government Obligations.

                  Section 4.10. Reinstatement. If the Trustee (or Paying Agent)
is unable to apply any money or Government Obligations in accordance with
Section 4.6 by reason of any order or judgment of any court or governmental
authority enjoining, restraining or otherwise prohibiting such application, then
the Company's obligations under this Indenture and the Securities shall be
revived and reinstated, with present and prospective effect, as though no
deposit had occurred pursuant to Section 4.6, until such time as the Trustee (or
Paying Agent) is permitted to apply all such money or Government Obligations in
accordance with Section 4.6; provided, however, that if the Company makes any
payment to the Trustee (or Paying Agent) of principal, premium, if any, or
interest on any Security following the reinstatement of its obligations, the
Trustee (or Paying Agent) shall promptly pay any such amount to the Holders of
the Securities and the Company shall be subrogated to the rights of the Holders
of such Securities to receive such payment from the money and Government
Obligations held by the Trustee (or Paying Agent).

Event of Default and whether it shall be voluntary or involuntary or be effected
by operation of law or pursuant to any judgment, decree or order of any court or
any order, rule or regulation of any administrative or governmental body):

                  (1) the Company defaults in the payment of interest on any
         Security of that series or any interest coupon appertaining thereto or
         any additional amount payable with respect to any Security of that
         series as specified pursuant to Section 3.1(b)(16) when the same
         becomes due and payable and such default continues for a period of 30
         days;

                  (2) the Company defaults in the payment of any installment of
         the principal of or any premium on any Security of that series when the

         covenants in, or any of the provisions of, this Indenture with respect

         provision for which non-compliance is elsewhere in this Section
         specifically dealt with), and such non- compliance continues for a
         period of 90 days after there has been given, by registered or
         certified mail, return receipt requested, to the Company by the Trustee
         or to the Company and the Trustee by the Holders of at least 25% in
         aggregate principal amount of the Outstanding Securities of the series,
         a written notice specifying such default or breach and requiring it to
         be remedied and stating that such notice is a "Notice of Default"
         hereunder;

                  (4) the Company defaults under any mortgage, indenture or
         instrument under which there may be issued, or by which there may be
         secured or evidenced, any Debt (including this Indenture) having an
         aggregate principal amount outstanding of at least $25,000,000, whether
         such Debt now exists or shall hereafter be created, and, as a result of
         such default, such Debt shall become due and payable, whether by
         acceleration or otherwise, and such acceleration shall not be
         rescinded, annulled or cured within a period of 30 days after there has

         Trustee shall have received written notice thereof from the Company,
         from any Holder, from the holder of any such Debt or from the trustee
         under any such agreement or other instrument); provided, however, that
         if such default under such mortgage, indenture or instrument is
         remedied or cured by the Company or waived by the holders of such Debt,
         then the Event of Default hereunder by reason thereof shall be deemed
         likewise to have been thereupon remedied, cured or waived without

         and in effect for 90 days; or

                  (7) there occurs any other Event of Default provided as
         contemplated by Section 3.1 with respect to Securities of that series.

                  The term "Bankruptcy Law" means Title 11, United States
Bankruptcy Code of 1978, as amended, or any similar United States federal or
state law relating to bankruptcy, insolvency, receivership, reorganization or
relief of debtors or any amendment to, successor to or change in any such law.
The term "Custodian" means any receiver, trustee, assignee, liquidator,
custodian, sequestrator or similar official under any Bankruptcy Law.

                  Section 5.2. Acceleration; Rescission and Annulment. If an
Event of Default with respect to the Securities of any series at the time
Outstanding (other than an Event of Default specified in clause (5) or (6) of
Section 5.1) occurs and is continuing, the Trustee or the Holders of at least
25% in aggregate principal amount of all of the Outstanding Securities of that
series, by written notice received by the Company (and, if given by the Holders,
received by the Trustee), may declare the principal (or, if the Securities of
that series are Original Issue Discount Securities or Indexed Securities, such
portion of the principal amount as may be specified in the terms of that series)
of and accrued interest, if any, on all the Securities of that series to be due
and payable and upon any such declaration such principal (or, in the case of
Original Issue Discount Securities or Indexed Securities, such specified amount)
and interest, if any, shall be immediately due and payable, provided that the
payment of principal and interest on such Securities shall remain subordinated
to the extent provided in Article 15. If an Event of Default specified in clause
(5) or (6) of Section 5.1 with respect to the Securities of any series at the
time Outstanding occurs and is continuing, then the principal (or, if the
Securities of that series are Original Issue Discount Securities or Indexed
Securities, such portion of the principal amount as may be specified in the
terms of that series) of and accrued interest, if any, on all the Securities of
that series shall ipso facto be immediately due and payable without any
declaration or act on the part of the Trustee or any Holder of such


                                       53
<PAGE>   62
Securities, provided that the payment of principal and interest on such
Securities shall remain subordinated to the extent provided in Article 15.

                  At any time after such a declaration of acceleration with
respect to Securities of any series has been made and before a judgment or
decree for payment of the money due has been obtained by the Trustee as
hereinafter in this Article provided, the Holders of a majority in aggregate
principal amount of the Outstanding Securities of that series, by written notice
to the Trustee, may rescind and annul such declaration and its consequences if
all existing Defaults and Events of Default with respect to Securities of that
series, other than the non-payment of the principal of Securities of that series
which have become due solely by such declaration of acceleration, have been
cured or waived as provided in Section 5.7. No such rescission shall affect any
subsequent default or impair any right consequent thereon.

                  Section 5.3. Collection of Indebtedness and Suits for
Enforcement by Trustee. The Company covenants that if

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

                  (2) default is made in the payment of the principal of (or
         premium, if any, on) any Security at the Maturity thereof, the Company
         will, upon demand of the Trustee, pay to it, for the benefit of the
         Holders of such Securities or interest coupons, if any, the whole
         amount then due and payable on such Securities for principal, premium,
         if any, and interest and, to the extent that payment of such interest
         shall be legally enforceable, interest on any overdue principal,
         premium, if any, and on any overdue interest, at the rate or rates
         prescribed therefor in such Securities or interest coupons, if any,
         and, in addition thereto, such further amount as shall be sufficient to
         cover the costs and expenses of collection, including all amounts due
         the Trustee, its agents and counsel under Section 6.7.

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


                                       54
<PAGE>   63
the property of the Company or any other obligor upon the Securities, wherever
situated.

                  If an Event of Default with respect to Securities of any
series occurs and is continuing, the Trustee may in its discretion proceed to
protect and enforce its rights and the rights of the Holders of Securities of
such series by such appropriate judicial proceedings as the Trustee shall deem
most effectual to protect and enforce any such rights, whether for the specific
enforcement of any covenant or agreement in this Indenture or in aid of the
exercise of any power granted herein, or to secure any other proper remedy,
subject, however, to Section 5.8.

                  Section 5.4. Trustee May File Proofs of Claim. In case of any
judicial proceeding relative to the Company (or any other obligor upon the
Securities), 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 the Trustee allowed in any such proceeding. In particular, the
Trustee shall be 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 6.7.

                  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 of a Security or interest coupon any plan of reorganization, arrangement,
adjustment or composition affecting the Securities or the rights of any Holder
of a Security or interest coupon thereof or to authorize the Trustee to vote in
respect of the claim of any Holder of a Security or interest coupon in any such
proceeding; provided, however, that the Trustee may, on behalf of the Holders,
vote for the election of a trustee in bankruptcy or similar official and be a
member of a creditors' or other similar committee.

                  Section 5.5. Trustee May Enforce Claims Without Possession of
Securities. All rights of action and claims under this Indenture or the
Securities may be prosecuted and enforced by the Trustee without the possession
of any of the Securities or the production thereof in any proceeding relating
thereto.

<PAGE>   64
                  Section 5.6. Delay or Omission Not Waiver. No delay or
omission by the Trustee or any Holder of any Securities to exercise any right or
remedy accruing upon an Event of Default shall impair any such right or remedy
or constitute a waiver of or acquiescence in any such Event of Default.

                  Section 5.7. Waiver of Past Defaults. The Holders of not less
than a majority in aggregate principal amount of Outstanding Securities of any
series by written notice to the Trustee may waive on behalf of the Holders of
all Securities of such series and any interest coupons appertaining thereto a
past Default or Event of Default with respect to that series and its
consequences except (i) a Default or Event of Default in the payment of the
principal of, premium, if any, or interest on any Security of such series or any
interest coupon appertaining thereto or (ii) in respect of a covenant or
provision hereof which pursuant to Article 8 cannot be amended or modified
without the consent of the Holder of each Outstanding Security of such series
affected. Upon any such waiver, such Default shall cease to exist, and any Event
of Default arising therefrom shall be deemed to have been cured, for every
purpose of this Indenture but no such waiver shall extend to any subsequent or
other default or impair any right consequent thereon.

                  Section 5.8. Control by Majority. The Holders of not less than
a majority in aggregate principal amount of the Outstanding Securities of each
series affected (with each such series voting as a class) shall have the right
to direct the time, method and place of conducting any proceeding for any remedy
available to the Trustee or exercising any trust or power conferred on it with
respect to Securities of that series; provided, however, that (i) the Trustee
may refuse to follow any direction that conflicts with any governmental rule or
law or this Indenture, (ii) the Trustee may refuse to follow any direction that
is unduly prejudicial to the rights of the Holders of Securities of such series
not consenting, or that would in the good faith judgment of the Trustee have a
substantial likelihood of involving the Trustee in personal liability without
adequate indemnity having been offered therefor and (iii) subject to Section
6.1, the Trustee may take any other action deemed proper by the Trustee which is
not inconsistent with such direction.

                  Section 5.9. Limitation on Suits by Holders. No Holder of any
Security of any series or any interest coupons appertaining thereto shall have
any right to institute any proceeding, judicial or otherwise, with respect to
this Indenture, or for the appointment of a receiver or trustee, or for any
other remedy hereunder, unless:


                                       56
<PAGE>   65
                  (1) the Holder has previously given written notice to the
         Trustee of a continuing Event of Default with respect to the Securities
         of that series;

                  (2) the Holders of at least 25% in aggregate principal amount
         of the Outstanding Securities of that series have made a written
         request to the Trustee to institute proceedings in respect of such
         Event of Default in its own name as Trustee hereunder;

                  (3) such Holder or Holders have offered to the Trustee
         indemnity satisfactory to the Trustee against any loss, liability or
         expense to be, or which may be, incurred by the Trustee in pursuing the
         remedy;

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

                  (5) during such 60-day period, the Holders of a majority in
         aggregate principal amount of the Outstanding Securities of that series
         have not given to the Trustee a direction inconsistent with such
         written request.

                  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 of such Holders, or to
obtain or to seek to obtain priority or preference over any other of such
Holders or to enforce any right under this Indenture, except in the manner
herein provided and for the equal and ratable benefit of all of such Holders.

                  Section 5.10. Rights of Holders to Receive Payment.
Notwithstanding any other provision of this Indenture, but subject to Section
9.2, the right of any Holder of a Security or interest coupon to receive payment
of principal of, premium, if any, and, subject to Sections 3.5 and 3.7, interest
on the Security, on or after the respective due dates expressed in the Security
(or, in case of redemption, on the Redemption Dates), the right of any Holder of
an interest coupon to receive payment of interest due as provided in such
interest coupon, or to bring suit for the enforcement of any such payment on or
after such respective dates, and the right, if any, to convert or exchange such
Security in accordance with Article 14, shall not be impaired or affected
without the consent of such Holder.

                  Section 5.11. Application of Money Collected. If the Trustee
collects any money pursuant to this Article, it shall pay out the money in the
following order, at the date or dates fixed by the Trustee and, in case of the


                                       57
<PAGE>   66
distribution of such money on account of principal, premium, if any, or
interest, upon presentation of the Securities and interest coupons, if any, and
the notation thereon of the payment if only partially paid and upon surrender
thereof if fully paid:

                  First: to the Trustee for amounts due under Section 6.7;

                  Second: to Holders of Securities and interest coupons in
respect of which or for the benefit of which such money has been collected for
amounts due and unpaid on such Securities for principal of, premium, if any, and
interest, ratably, without preference or priority of any kind, according to the
amounts due and payable on such Securities for principal, premium, if any, and
interest, respectively; and

                  Third: the balance, if any, to the Company.

                  The Holders of each series of Securities denominated in ECU,
any other currency unit or a Foreign Currency and any matured interest coupons
relating thereto shall be entitled to receive a ratable portion of the amount
determined by the Trustee by converting the principal amount Outstanding of such
series of Securities and matured but unpaid interest on such series of
Securities in the currency in which such series of Securities is denominated
into Dollars at the Market Exchange Rate as of the date of declaration of
acceleration of Maturity of the Securities.

                  The Trustee may fix a record date and payment date for any
payment to Holders pursuant to this Section 5.11. At least 15 days before such
record date, the Trustee shall mail to each Holder and the Company a notice that
states the record date, the payment date and the amount to be paid.

                  Section 5.12. 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 as though no such
proceeding had been instituted.

                  Section 5.13. Rights and Remedies Cumulative. Except as
otherwise provided with respect to the replacement or payment of mutilated,
destroyed, lost or stolen Securities in the last paragraph of Section 3.6, no
right or remedy herein conferred upon or reserved to the Trustee or the Holders
is intended to be exclusive of any other right or remedy, and every right and
remedy shall, to the extent permitted by law, be cumulative and in addition to
every other right and remedy given hereunder or now or hereafter existing at law
or in equity or otherwise. The assertion or employment of any right or remedy
hereunder, or otherwise, shall not prevent the concurrent assertion or
employment of any other appropriate right or remedy.

                  Section 5.14. Undertaking for Costs. In any suit for the
enforcement of any right or remedy under this Indenture, or in any suit against
the Trustee for any action taken, 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, however,
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.

                  Section 5.15. Waiver of Stay, Extension or Usury 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 or any usury or other law
wherever enacted, now or at any time hereafter in force, which would prohibit or
forgive the Company from paying all or any portion of the principal, of, and
premium, if any, or interest on the Securities contemplated herein or in the
Securities or which may affect the covenants or the performance of this
Indenture; and the Company (to the extent that it may lawfully do so) hereby
expressly waives all benefit or advantage of any such law, and covenants that it
will not hinder, delay or impede the execution of any power herein granted to
the Trustee, but will suffer and permit the execution of every such power as
though no such law had been enacted.

Act.


                                       59
<PAGE>   68
Notwithstanding the foregoing, no provision of this Indenture shall require the
Trustee to expend or risk its own funds or otherwise incur any financial
liability in the performance of any of its duties hereunder, or in the exercise
of any of its rights or powers, if it shall have reasonable grounds for
believing that repayment of such funds or adequate indemnity against such risk
or liability is not reasonably assured to it. Whether or not therein expressly
so provided, every provision of this Indenture relating to the conduct or
affecting the liability of or affording protection to the Trustee shall be
subject to the provisions of this Section.

                  Section 6.2. Notice of Defaults. If a default occurs hereunder
with respect to Securities of any series, the Trustee shall give the Holders of
Securities of such series notice of such default as and to the extent provided
by the Trust Indenture Act; provided, however, that in the case of any default
of the character specified in Section 5.1(3) with respect to Securities of such
series, no such notice to Holders shall be given until at least 30 days after
the occurrence thereof. For the purpose of this Section, the term "default"
means any event which is, or after notice or lapse of time or both would become,
an Event of Default with respect to Securities of such series.

provisions of Section 6.1:

         instrument, opinion, report, notice, request, direction, consent,
         order, bond, debenture, note, other evidence of indebtedness or other
         paper or document believed by it to be genuine and to have been signed
         or presented by the proper party or parties;

                  (2) any request or direction of the Company mentioned herein
         shall be sufficiently evidenced by a Company Request or Company Order,
         and any resolution of the Board of Directors shall be sufficiently
         evidenced by a Board Resolution;

                  (3) whenever in the administration of this Indenture the
         Trustee shall deem it desirable that a matter be proved or established
         prior to taking, suffering or omitting any action hereunder, the
         Trustee (unless other evidence be herein specifically prescribed) may,
         in the absence of bad faith on its part, rely upon an Officers'
         Certificate;


                                       60
<PAGE>   69
                  (4) the Trustee may consult with counsel and the written
         advice of such counsel or any Opinion of Counsel shall be full and
         complete authorization and protection in respect of any action taken,
         suffered or omitted by it hereunder in good faith and in reliance
         thereon;

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

                  (6) the Trustee shall not be bound to make any investigation
         into the facts or matters stated in any resolution, certificate,
         statement, instrument, opinion, report, notice, request, direction,
         consent, order, bond, debenture, note, other evidence of indebtedness
         or other paper or document, but the Trustee, in its discretion, may
         make such further inquiry or investigation into such facts or matters
         as it may see fit, and, if the Trustee shall determine to make such
         further inquiry or investigation, it shall be entitled to examine the
         books, records and premises of the Company, personally or by agent or
         attorney;

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

                  (8) except with respect to Section 9.1, the Trustee shall have
         no duty to inquire as to the performance by the Company of the
         covenants set forth in Article 9 beyond its good faith review of any
         certificates or other notices received by it from the Company.

                  Section 6.4. Not Responsible for Recitals or Issuance of
Securities. The recitals contained herein and in the Securities, except the
Trustee's certificates of authentication, shall be taken as the statements of
the Company and neither the Trustee nor any Authenticating Agent assumes any
responsibility for their correctness. The Trustee makes no representations as to
the validity or sufficiency of this Indenture or of the Securities. Neither the
Trustee nor any Authenticating Agent shall be accountable for the use or
application by the Company of Securities or the proceeds thereof.

                  Section 6.5. May Hold Securities. The Trustee, any
Authenticating Agent, any Paying Agent, any Security Registrar or any other
agent of the Company or the Trustee, in its individual or any other capacity,
may become the owner or pledgee of Securities and, subject to Sections 6.8 and
6.13, may otherwise deal with the Company and any other obligor upon the
Securities with the same rights it would have if it were not Trustee,
Authenticating Agent, Paying Agent, Security Registrar or such other agent.

   
                  Section 6.6. Money Held in Trust. Money held by the Trustee in
trust hereunder need not be segregated from other funds except to the extent
required by law. The Trustee shall be under no liability for interest on any
money received by it hereunder except as otherwise agreed with the Company.
    

                  Section 6.7. Compensation and Reimbursement. The Company
agrees

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

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

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

shall acquire a conflicting interest within the meaning of the Trust Indenture
Act, the Trustee shall either eliminate such interest or resign, to the extent

manner provided by, and subject to the provisions of, the Trust Indenture Act

shall at all times be a Trustee hereunder which shall be a Person that is
eligible pursuant to the Trust Indenture Act to act as such, has a combined
capital and surplus of at least $50,000,000 and has its Corporate Trust Office
located in the Borough of Manhattan, The City of New York. If such Person
publishes reports of condition at least annually, pursuant to law or to the
requirements of its supervising or examining authority, then for the purposes of
this Section, the combined capital and surplus of such Person shall be deemed to
be its combined capital and surplus as set forth in its most recent report of
condition so published. If at any time the Trustee shall cease to be eligible in
accordance with the provisions of this Section, it shall resign immediately in
the manner and with the effect hereinafter specified in this Article.

                  Section 6.10. Resignation and Removal; Appointment of
Successor. No resignation or removal of the Trustee and no appointment of a
successor Trustee pursuant to this Article shall become effective until the
acceptance of appointment by the successor Trustee in accordance with the
applicable requirements of Section 6.11.

                  The Trustee may resign at any time with respect to the
Securities of one or more series by giving written notice thereof to the
Company. If the instrument of acceptance by a successor Trustee required by
Section 6.11 shall not have been delivered to the Trustee within 30 days after
the giving of such notice of


                                       63
<PAGE>   72
resignation, the resigning Trustee may petition any court of competent
jurisdiction for the appointment of a successor Trustee with respect to the
Securities of such series.

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

                  If at any time:

                  (1) the Trustee shall fail to comply with Section 6.8 after
         written request therefor by the Company or by any Holder who has been a
         bona fide Holder of a Security for at least six months, or

                  (2) the Trustee shall cease to be eligible under Section 6.9
         and shall fail to resign after written request therefor by the Company
         or by any such Holder, or

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

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

                  If the Trustee shall resign, be removed or become incapable of
acting, or if a vacancy shall occur in the office of Trustee for any cause, with
respect to the Securities of one or more series, the Company, by a Board
Resolution, shall promptly appoint a successor Trustee or Trustees with respect
to the Securities of that or those series (it being understood that any such
successor Trustee may be appointed with respect to the Securities of one or more
or all of such series and that at any time there shall be only one Trustee with
respect to the Securities of any particular series) and shall comply with the
applicable requirements of Section 6.11. If, within one year after such
resignation, removal or


                                       64
<PAGE>   73
incapability, or the occurrence of such vacancy, a successor Trustee with
respect to the Securities of any series shall be appointed by Act of the Holders
of a majority in principal amount of the Outstanding Securities of such series
delivered to the Company and the retiring Trustee, the successor Trustee so
appointed shall, forthwith upon its acceptance of such appointment in accordance
with the applicable requirements of Section 6.11, become the successor Trustee
with respect to the Securities of such series and to that extent supersede the
successor Trustee appointed by the Company. If no successor Trustee with respect
to the Securities of any series shall have been so appointed by the Company or
the Holders and accepted appointment in the manner required by Section 6.11, any
Holder who has been a bona fide Holder of a Security of such series for at least
six months may, on behalf of himself and all others similarly situated, petition
any court of competent jurisdiction for the appointment of a successor Trustee
with respect to the Securities of such series. The Company shall give notice of
each resignation and each removal of the Trustee with respect to the Securities
of any series and each appointment of a successor Trustee with respect to the
Securities of any series to all Holders of Securities of such series in the
manner provided in Section 1.6. Each notice shall include the name of the
successor Trustee with respect to the Securities of such series and the address
of its Corporate Trust Office.

                  Section 6.11. Acceptance of Appointment by Successor. In case
of the appointment hereunder of a successor Trustee with respect to all
Securities, every such successor Trustee so appointed shall execute, acknowledge
and deliver to the Company and to the retiring Trustee an instrument accepting
such appointment, and thereupon the resignation or removal of the retiring
Trustee shall become effective and such successor Trustee, without any further
act, deed or conveyance, shall become vested with all the rights, powers, trusts
and duties of the retiring Trustee; but, on the request of the Company or the
successor Trustee, such retiring Trustee shall, upon payment of its charges,
execute and deliver an instrument transferring to such successor Trustee all the
rights, powers and trusts of the retiring Trustee and shall duly assign,
transfer and deliver to such successor Trustee all property and money held by
such retiring Trustee hereunder.

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


                                       65
<PAGE>   74
retiring Trustee with respect to the Securities of that or those series as to
which the retiring Trustee is not retiring shall continue to be vested in the
retiring Trustee, and (3) shall add to or change any of the provisions of this
Indenture as shall be necessary to provide for or facilitate the administration
of the trusts hereunder by more than one Trustee, it being understood that
nothing herein or in such supplemental indenture shall constitute such Trustees
co-trustees of the same trust and that each such Trustee shall be trustee of a
trust or trusts hereunder separate and apart from any trust or trusts hereunder
administered by any other such Trustee; and upon the execution and delivery of
such supplemental indenture the resignation or removal of the retiring Trustee
shall become effective to the extent provided therein and each such successor
Trustee, without any further act, deed or conveyance, shall become vested with
all the rights, powers, trusts and duties of the retiring Trustee with respect
to the Securities of that or those series to which the appointment of such
successor Trustee relates; but, on request of the Company or any successor
Trustee, such retiring Trustee shall duly assign, transfer and deliver to such
successor Trustee all property and money held by such retiring Trustee hereunder
with respect to the Securities of that or those series to which the appointment
of such successor Trustee relates.

                  Upon request of any such successor Trustee, the Company shall
execute any and all instruments for more fully and certainly vesting in and
confirming to such successor Trustee all such rights, powers and trusts referred
to in the first or second preceding paragraph, as the case may be.

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

                  Section 6.12. Merger, Conversion, Consolidation or Succession
to Business. Any corporation into which the Trustee may be merged or converted
or with which it may be consolidated, or any corporation resulting from any
merger, conversion or consolidation to which the Trustee shall be a party, or
any corporation succeeding to all or substantially all the corporate trust
business of the Trustee, shall be the successor of the Trustee hereunder,
provided such corporation shall be otherwise qualified and eligible under this
Article, without the execution or filing of any paper or any further act on the
part of any of the parties hereto. In case any Securities shall have been
authenticated, but not delivered, by the Trustee


                                       66
<PAGE>   75
then in office, any successor by merger, conversion or consolidation to such
authenticating Trustee may adopt such authentication and deliver the Securities
so authenticated with the same effect as if such successor Trustee had itself
authenticated such Securities.

                  Section 6.13. Preferential Collection of Claims Against
Company. If and when the Trustee shall be or become a creditor of the Company
(or any other obligor upon the Securities), the Trustee shall be subject to the
provisions of the Trust Indenture Act regarding the collection of claims against
the Company (or any such other obligor).

   
                  Section 6.14. Appointment of Authenticating Agent. The Trustee
may appoint an Authenticating Agent or Agents with respect to one or more series
of Securities which shall be authorized to act on behalf of the Trustee to
authenticate Securities of such series issued upon original issue and upon
exchange, registration of transfer or partial redemption thereof or pursuant to
Section 3.6, and Securities so authenticated shall be entitled to the benefits
of this Indenture and shall be valid and obligatory for all purposes as if
authenticated by the Trustee hereunder. Wherever reference is made in this
Indenture to the authentication and delivery of Securities by the Trustee or the
Trustee's certificate of authentication, such reference shall be deemed to
include authentication and delivery on behalf of the Trustee by an
Authenticating Agent and a certificate of authentication executed on behalf of
the Trustee by an Authenticating Agent. Each Authenticating Agent shall be
acceptable to the Company and shall at all times be a corporation organized and
doing business under the laws of the United States of America, any State thereof
or the District of Columbia, authorized under such laws to act as Authenticating
Agent, having a combined capital and surplus of not less than $50,000,000 and
subject to supervision or examination by Federal or State authority. If such
Authenticating Agent publishes reports of condition at least annually, pursuant
to law or to the requirements of said supervising or examining authority, then
for the purposes of this Section, the combined capital and surplus of such
Authenticating Agent shall be deemed to be its combined capital and surplus as
set forth in its most recent report of condition so published. If at any time an
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, such Authenticating Agent shall resign immediately
in the manner and with the effect specified in this Section.
    

                  Any corporation into which an Authenticating Agent may be
merged or converted or with which it may be consolidated, or any corporation
resulting from any merger, conversion or consolidation to which such
Authenticating Agent shall be a party, or any corporation succeeding to the
corporate agency or


                                       67
<PAGE>   76
corporate trust business of an Authenticating Agent, shall continue to be an
Authenticating Agent, provided such corporation shall be otherwise eligible
under this Section, without the execution or filing of any paper or any further
act on the part of the Trustee or the Authenticating Agent.

                  An Authenticating Agent may resign at any time by giving
written notice thereof to the Trustee and to the Company. The Trustee may at any
time terminate the agency of an Authenticating Agent by giving written notice
thereof to such Authenticating Agent and to the Company. Upon receiving such a
notice of resignation or upon such a termination, or in case at any time such
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, the Trustee may appoint a successor Authenticating
Agent which shall be acceptable to the Company and shall give notice of such
appointment in the manner provided in Section 1.6 to all Holders of Securities
of the series with respect to which such Authenticating Agent will serve. Any
successor Authenticating Agent upon acceptance of its appointment hereunder
shall become vested with all the rights, powers and duties of its predecessor
hereunder, with like effect as if originally named as an Authenticating Agent.
No successor Authenticating Agent shall be appointed unless eligible under the
provisions of this Section.

                  The Trustee agrees to pay to each Authenticating Agent from
time to time reasonable compensation for its services under this Section, and
the Trustee shall be entitled to be reimbursed for such payments, subject to the
provisions of Section 6.7.

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

                  This is one of the Securities of the series designated therein
referred to in the within-mentioned Indenture.

             CONSOLIDATION, MERGER OR SALE OF ASSETS BY THE COMPANY


                  Section 7.1. Consolidation, Merger or Sale of Assets
Permitted. The Company shall not consolidate with or merge into, or sell,
transfer, lease or otherwise dispose of its properties and assets as, or
substantially as, an entirety to, any Person unless:

                           (1) (A) the Company will be the surviving entity or
                  (B) the Person formed by or surviving any such consolidation
                  or merger (if other than the Company), or to which such sale,
                  transfer, lease or other disposition shall have been made, is
                  an entity organized and existing under the laws of the United
                  States, any State thereof or the District of Columbia;

                  all the obligations of the Company under the Securities and

                           (3) immediately after giving effect to such
                  consolidation, merger, sale, transfer, lease or other
                  disposition, no Default or Event of Default exists; and
    
   
                           (4) with respect to any series of Securities, the
                  Company satisfies such other conditions, if any, established
                  pursuant to and in accordance with Section 3.1.
    

                  The Company shall deliver to the Trustee prior to the proposed
consolidation, merger, sale, transfer, lease or other disposition an Officers'
Certificate to the foregoing effect and an Opinion of Counsel stating that the
proposed consolidation, merger, sale, transfer, lease or other disposition and

                             SUPPLEMENTAL INDENTURES


                  Section 8.1. Supplemental Indentures Without Consent of
Holders. Without the consent of any Holders, the Company and the Trustee, at any
time and from time to time, may enter into indentures supplemental hereto, in
form reasonably satisfactory to the Trustee, for any of the following purposes:

                           (1) to evidence the succession of another Person to
                  the Company and the assumption by any such successor of the
                  covenants and obligations of the Company herein and in the
                  Securities and any interest coupons appertaining thereto; or

                  series of Securities, stating that such covenants are
                  expressly being included solely for the benefit of such
                  series) or to surrender any right or power herein conferred
                  upon the Company; or

                  series created prior to the execution of such supplemental
                  indenture which is entitled to the benefit of such provision;

                  the Securities of one or more series and to add to or change
                  any of the provisions of this Indenture as shall be necessary
                  to provide for or facilitate the administration of the trusts

                  interests of the Holders of Securities of any series; or

                           (11) to make provision not adverse to the Holders of
                  Outstanding Securities of any series with respect to any
                  conversion or exchange rights of Holders pursuant to the
                  requirements of Article 14, including providing for the
                  conversion or exchange of the Securities into any Equity

                  Indenture with respect to the subordination of Outstanding
                  Securities of any series in a manner not adverse to the
                  Holders thereof; or

                           (14) to modify, eliminate or add to the provisions of
                  this Indenture to such extent as shall be necessary to effect
                  the qualification of this Indenture under the Trust Indenture
                  Act or under any similar federal statute subsequently enacted,
                  and to add to this Indenture such other provisions as may be
                  expressly required under the Trust Indenture Act.

                  Section 8.2. Supplemental Indentures With Consent of Holders.
With the consent of the Holders of not less than a majority of the aggregate
principal amount of the Outstanding Securities of all series adversely affected
by such supplemental indenture (voting as one class), by Act of said Holders
delivered to the Company, the Company and the Trustee may enter into an
indenture or indentures supplemental hereto to add any provisions to or to
change in any manner or eliminate any provisions of this Indenture or of any
other indenture supplemental hereto or to modify in any manner the rights of the
Holders of such Securities; provided, however, that without the consent of the
Holder of each Outstanding Security affected thereby, an amendment under this
Section may not:

                           (1) change the Stated Maturity of the principal of,
                  or premium, if any, on, or any installment of principal of or

                  principal amount thereof or the rate of interest thereon or
                  any premium payable upon the redemption thereof, or change the

                  pursuant to Section 5.2, or change the currency or currency
                  unit in which any Securities or any premium or the interest
                  thereon is payable, or impair the right to institute suit for
                  the enforcement of any such payment on or after the Stated

                  the Redemption Date);

                           (2) reduce the percentage in principal amount of the
                  Outstanding Securities of any series, 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 reduce the requirements of Section
                  13.4 for quorum or voting;

                           (3) change any obligation of the Company to maintain
                  an office or agency in the places and for the purposes
                  specified in Section 9.2;

                           (4) make any change that adversely affects any right
                  to convert or exchange any Security to which the provisions of
                  Article 14 are applicable or, except as provided in this
                  Indenture, decrease the conversion or exchange rate or
                  increase the conversion or exchange price of any such
                  Security;

                           (5) modify the provisions in Article 15 of this
                  Indenture with respect to the subordination of Outstanding

                  thereof; or

                           (6) make any change in this Section 8.2 except to

                  the consent of the Holders of each Outstanding Security
                  affected thereby.

                  A supplemental indenture which changes or eliminates any
covenant or other provision of this Indenture which has expressly been included
solely for the benefit of one or more particular series of Securities, or which
modifies the rights of the Holders of Securities of such series with respect to
such covenant or other provision, shall be deemed not to affect the rights under
this Indenture of the Holders of Securities of any other series.

                  It is not necessary under this Section 8.2 for the Holders to
consent to the particular form of any proposed supplemental indenture, but it is
sufficient if they consent to the substance thereof.

                  Section 8.3. Compliance with Trust Indenture Act. Every
amendment to this Indenture or the Securities of one or more series shall be set


                                       73
<PAGE>   82
forth in a supplemental indenture that complies with the Trust Indenture Act as
then in effect.

                  Section 8.4. Execution of Supplemental Indentures. In
executing, or accepting the additional trusts created by, any supplemental
indenture permitted by this Article or the modification thereby of the trusts
created by this Indenture, the Trustee shall be entitled to receive, and
(subject to Section 6.1) shall be fully protected in relying upon, an Officers'
Certificate and 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 8.5. 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 Securities
theretofore or thereafter authenticated and delivered hereunder and of any
interest coupon appertaining thereto shall be bound thereby.

                  Section 8.6. Reference in Securities to Supplemental
Indentures. Securities, including any interest coupons, of any series
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 Securities
including any interest coupons of any series so modified as to conform, in the
opinion of 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 Securities including any interest coupons of such
series.

                  Section 8.7. Notice of Supplemental Indentures. Promptly after
the execution by the Company and the Trustee of any supplemental indenture
pursuant to the provisions of Section 8.2, the Company shall give notice thereof
to the Holders of each Outstanding Security affected, in the manner provided for
in Section 1.6, setting forth in general terms the substance of such
supplemental indenture. Any failure of the Company to give such notice, or any
defect therein, shall not, however, in any way impair or affect the validity of
any such supplemental indenture.

                                    COVENANTS

                  Section 9.1. Payment of Principal, Premium, if any, and
Interest. The Company covenants and agrees for the benefit of the Holders of
each series of Securities that it will duly and punctually pay the principal of,
premium, if any, and interest, together with additional amounts, if any, on the
Securities of that series in accordance with the terms of the Securities of such
series, any interest coupons appertaining thereto and this Indenture; provided,
however, that amounts properly withheld under the Internal Revenue Code of 1986,
as amended, by any Person from a payment to any Holder of Securities, after
having requested such Holder to provide applicable information that would allow
such Person to make such payment without withholding, shall be considered as
having been paid by the Company to such Holder for purposes of this Indenture.
An installment of principal, premium, if any, or interest shall be considered
paid on the date it is due if there shall have been sent to the Trustee or
Paying Agent by wire transfer, or if the Trustee or Paying Agent otherwise
holds, on that date money designated for and sufficient to pay the installment.

                  Section 9.2. Maintenance of Office or Agency. Unless otherwise
specified as contemplated by Section 3.1, if Securities of a series are issued
as Registered Securities, the Company will maintain in each Place of Payment for
any series of Securities an office or agency where Securities of that series may
be presented or surrendered for payment, where Securities of that series may be
surrendered for registration of transfer or exchange and where notices and
demands to or upon the Company in respect of the Securities of that series and
this Indenture may be served. Unless otherwise specified as contemplated by
Section 3.1, if Securities of a series are issuable as Bearer Securities, the
Company will maintain, (i) subject to any laws or regulations applicable
thereto, an office or agency in a Place of Payment for that series which is
located outside the United States where Securities of that series and related
interest coupons may be presented and surrendered for payment; provided,
however, that if the Securities of that series are listed on The International
Stock Exchange of the United Kingdom and the Republic of Ireland Limited, the
Luxembourg Stock Exchange or any other stock exchange located outside the United
States and such stock exchange shall so require, the Company will maintain a
Paying Agent for the Securities of that series in London, Luxembourg or any
other required city located outside the United States, as the case may be, so
long as the Securities of that series are listed on such exchange, and (ii)
subject to any laws or regulations applicable thereto, an office or agency in a
Place of Payment for that series which is located outside the United 


                                       75
<PAGE>   84
States, where Securities of that series may be surrendered for exchange and
where notices and demands to or upon the Company in respect of the Securities of
that series and this Indenture may be served. The Company will give prompt
written notice to the Trustee of the location, and any change in the location,
of any 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.

                  Unless otherwise specified as contemplated by Section 3.1, no
payment of principal, premium or interest on Bearer Securities shall be made at
any office or agency of the Company in the United States, by check mailed to any
address in the United States, by transfer to an account located in the United
States or upon presentation or surrender in the United States of a Bearer
Security or interest coupon for payment, even if the payment would be credited
to an account located outside the United States; provided, however, that, if the
Securities of a series are denominated and payable in Dollars, payment of
principal of and any premium or interest on any such Bearer Security shall be
made at the office of the Company's Paying Agent in the Borough of Manhattan,
The City of New York, if (but only if) payment in Dollars of the full amount of
such principal, premium or interest, as the case may be, at all offices or
agencies outside the United States maintained for the purpose by the Company in
accordance with this Indenture is illegal or effectively precluded by exchange
controls or other similar restrictions.

                  Unless otherwise specified as contemplated by Section 3.1, the
Company may also from time to time designate one or more other offices or
agencies where the Securities (including any interest coupons, if any) of one or
more series 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 each Place of Payment for
Securities (including any interest coupons, if any) of any series 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.

                  Unless otherwise specified as contemplated by Section 3.1, the
Trustee shall initially serve as Paying Agent.

                  Section 9.3. Money for Securities Payments to Be Held in
Trust; Unclaimed Money. If the Company shall at any time act as its own Paying
Agent with respect to any series of Securities and any interest coupons
appertaining thereto, it will, on or before each due date of the principal of,
premium, if any, or interest on any of the Securities of that series, segregate
and hold in trust for the benefit of the Persons entitled thereto a sum
sufficient to pay the principal, premium, if any, or interest so becoming due
until such sums shall be paid to such Persons or otherwise disposed of as herein
provided and will promptly notify the Trustee in writing of its action or
failure so to act.

                  Whenever the Company shall have one or more Paying Agents for
any series of Securities and any interest coupons appertaining thereto, it will,
prior to each due date of the principal of or any premium or interest on any
Securities of that series, deposit with a Paying Agent a sum sufficient to pay
such amount, such sum to be held as provided by the 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 for any series of
Securities other than the Trustee to execute and deliver to the Trustee an
instrument in which such Paying Agent shall agree with the Trustee, subject to
the provisions of this Section, that such Paying Agent will:

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

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

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

                  The Company may at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture or for any other purpose, pay, or
by Company Order direct any Paying Agent to pay, to the Trustee all sums held in


                                       77
<PAGE>   86
trust by the Company or such Paying Agent, such sums to be held by the Trustee
upon the terms set forth in this Indenture; 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 any principal of or
premium or interest on any Security of any series and remaining unclaimed for
two years after such principal, premium, if any, 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 such Security
and interest coupon, if any, shall thereafter, as an unsecured general creditor,
look only to the Company for payment thereof, and all liability of the Trustee
or such Paying Agent with respect to such trust money, and all liability of the
Company as trustee thereof, shall thereupon cease; provided, however, that the
Trustee or such Paying Agent, before being required to make any such repayment,
may in the name and at the expense of the Company cause to be published once, in
an Authorized Newspaper in each Place of Payment with respect to such series, or
cause to be mailed to such Holder, notice that such money remains unclaimed and
that, after a date specified therein, which shall not be less than 30 days from
the date of such publication, any unclaimed balance of such money then remaining
will be repaid to the Company.

                  Section 9.4. Corporate Existence. Subject to Article 7, the
Company will at all times do or cause to be done all things necessary to
preserve and keep in full force and effect its corporate existence and its
rights and franchises; provided that nothing in this Section 9.4 shall prevent
the abandonment or termination of any right or franchise of the Company if it
shall be determined that such abandonment or termination is desirable in the
conduct of the business of the Company.

                  Section 9.5. Annual Review Certificate. The Company covenants
and agrees to deliver to the Trustee, within 120 days after the end of each
fiscal year of the Company, a certificate from the principal executive officer,
principal financial officer or principal accounting officer of the Company
stating that a review of the activities of the Company during such year and of
performance under this Indenture has been made under his or her supervision and
to the best of his or her knowledge, based on such review, the Company has
fulfilled all of its obligations under this Indenture throughout such year, or,
if there has been a default in the fulfillment of any such obligation,
specifying each such default known to him or her and the nature and status
thereof. For purposes of this


                                       78
<PAGE>   87
Section 9.5, such compliance shall be determined without regard to any period of
grace or requirement of notice provided under this Indenture.

                  Section 9.6 Waiver of Certain Covenants. Except as otherwise
specified as contemplated by Section 3.1 for Securities of such series, the
Company may, with respect to the Securities of any series, omit in any
particular instance to comply with any term, provision or condition set forth in
any covenant provided pursuant to Section 3.1(15), 8.1(2) or 8.1(7) for the
benefit of the Holders of such series if before the time for such compliance the
Holders of at least a majority in principal amount of the Outstanding Securities
of such series shall, by act of such Holders in accordance with Section 1.4,
either waive such compliance in such instance or generally waive compliance with
such term, provision or condition, but no such waiver shall extend to or affect
such term, provision or condition except to the extent so expressly waived, and,
until such waiver shall become effective, the obligations of the Company and the
duties of the Trustee in respect of any such term, provision or condition shall
remain in full force and effect.

any, that, at the time of such election, may be redeemed at the option of the
Company, shall be evidenced by or pursuant to a Board Resolution. In the case of
any such


                                       81
<PAGE>   90
redemption at the election of the Company of less than all the Securities or
interest coupons, if any, of any series, the Company shall, at least 45 days
prior to the Redemption Date fixed by the Company (unless a shorter notice shall
be satisfactory to the Trustee), notify the Trustee of such Redemption Date, of
the principal amount of Securities of such series to be redeemed and, if
applicable, of the tenor of the Securities to be redeemed. In the case of any
redemption of Securities (i) prior to the expiration of any restriction on such
redemption provided in the terms of such Securities or elsewhere in this
Indenture or (ii) pursuant to an election of the Company which is subject to a
condition specified in the terms of such Securities, the Company shall furnish
the Trustee with an Officers' Certificate evidencing compliance with such
restriction or condition.

                  Section 11.3. Selection of Securities to Be Redeemed. Unless
otherwise specified as contemplated by Section 3.1, if less than all the
Securities (including interest coupons, if any) of a series with the same terms
are to be redeemed, the Trustee, not more than 45 days prior to the Redemption
Date, shall select the Securities of the series to be redeemed in such manner as
the Trustee shall deem fair and appropriate. The Trustee shall make the
selection from Securities of the series that are Outstanding and that have not
previously been called for redemption and may provide for the selection for
redemption of portions (equal to the minimum authorized denomination for
Securities, including interest coupons, if any, of that series or any integral
multiple thereof) of the principal amount of Securities, including interest
coupons, if any, of such series of a denomination larger than the minimum
authorized denomination for Securities of that series. The Trustee shall
promptly notify the Company in writing of the Securities selected by the Trustee
for redemption and, in the case of any Securities selected for partial
redemption, the principal amount thereof to be redeemed. If the Company shall so
direct, Securities registered in the name of the Company, any Affiliate or any
Subsidiary thereof shall not be included in the Securities selected for
redemption.

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

                  Section 11.4. Notice of Redemption. Unless otherwise specified
as contemplated by Section 3.1, notice of redemption shall be given in the
manner


                                       82

Redemption Date to the Holders of the Securities to be redeemed.

                  All notices of redemption shall state:

                           (1) the Redemption Date;

                           (2) the Redemption Price;

                           (3) if less than all the Outstanding Securities of a
                  series are to be redeemed, the identification (and, in the
                  case of partial redemption, the principal amounts) of the
                  particular Security or Securities to be redeemed;

                           (4) the Place or Places of Payment where such
                  Securities, together in the case of Bearer Securities with all
                  interest coupons appertaining thereto, if any, maturing after
                  the Redemption Date, are to be surrendered for payment of the
                  Redemption Price;

                           (5) that Securities of the series called for
                  redemption and all unmatured interest coupons, if any,
                  appertaining thereto must be surrendered to the Paying Agent
                  to collect the Redemption Price;

                           (6) that, on the Redemption Date, the Redemption
                  Price will become due and payable upon each such Security, or
                  the portion thereof, to be redeemed and, if applicable, that
                  interest thereon will cease to accrue on and after said date;

                           (7) that the redemption is from a sinking fund, if
                  such is the case;

                           (8) that, unless otherwise specified in such notice,
                  Bearer Securities of any series, if any, surrendered for
                  redemption must be accompanied by all interest coupons
                  maturing subsequent to the Redemption Date or the amount of
                  any such missing interest coupon or interest coupons will be
                  deducted from the Redemption Price, unless security or
                  indemnity satisfactory to the Company, the Trustee and any
                  Paying Agent is furnished;

                           (9) the CUSIP number, if any, of the Securities;


                                       83
<PAGE>   92
                           (10) if applicable, the conversion or exchange price,
                  the date on which the right to convert or exchange the
                  Securities (or portions thereof to be redeemed) will terminate
                  and the place or places where such Securities may be
                  surrendered for conversion or exchange; and

                           (11) the procedures that a Holder must follow to
                  surrender the Securities so to be redeemed.

                           Notice of redemption of Securities to be redeemed
                  shall be given by the Company or, at the Company's request, by
                  the Trustee in the name and at the expense of the Company.

                  Section 11.5. Deposit of Redemption Price. On or prior to any
Redemption Date, the Company shall deposit with the Trustee or with a Paying
Agent (or, if the Company is acting as its own Paying Agent, segregate and hold
in trust as provided in Section 9.3) an amount of money in the currency or
currencies (including currency unit or units) in which the Securities of such
series are payable (except as otherwise specified pursuant to Section 3.1 for
the Securities of such series) sufficient to pay on the Redemption Date the
Redemption Price of, and (unless the Redemption Date shall be an Interest
Payment Date) interest accrued to the Redemption Date on, all Securities or
portions thereof which are to be redeemed on that date.

                  Unless any Security by its terms prohibits any redemption
obligation from being satisfied by delivering and crediting Securities
(including Securities redeemed otherwise than through a sinking fund), the
Company may deliver such Securities to the Trustee for crediting of an amount
equal to the then applicable Redemption Price for such Securities against such
payment obligation in accordance with the terms of such Securities and this
Indenture.

                  Section 11.6. Securities Payable on Redemption Date. Notice of
redemption having been given as aforesaid, the Securities so to be redeemed
shall, on the Redemption Date, become due and payable at the Redemption Price
therein specified, and from and after such date (unless the Company shall
default in the payment of the Redemption Price and accrued interest) such
Securities shall cease to bear interest and the interest coupons for any such
interest appertaining to any Bearer Security so to be redeemed, except to the
extent provided below, shall be void. Except as provided in the next succeeding
paragraph, upon surrender of any such Security, including interest coupons, if
any, for redemption in accordance with said notice, such Security shall be paid
by the Company at the Redemption


                                       84
<PAGE>   93
Price, together with accrued interest to the Redemption Date; provided, however,
that installments of interest on Bearer Securities whose Stated Maturity is on
or prior to the Redemption Date shall be payable only at an office or agency
located outside the United States and its possessions (except as otherwise
provided in Section 9.2) and, unless otherwise specified as contemplated by
Section 3.1, only upon presentation and surrender of interest coupons for such
interest; and provided, further, that, unless otherwise specified as
contemplated by Section 3.1, installments of interest on Registered Securities
that are due and payable on Interest Payment Dates that are on or prior to the
Redemption Date shall be payable to the Holders of such Securities, or one or
more Predecessor Securities, registered as such at the close of business on the
relevant Regular Record Dates according to their terms and the provisions of
Section 3.7.

                  If any Bearer Security surrendered for redemption shall not be
accompanied by all appurtenant interest coupons maturing after the Redemption
Date, such Bearer Security may be paid after deducting from the Redemption Price
an amount equal to the face amount of all such missing interest coupons, or the
surrender of such missing interest coupon or interest coupons may be waived by
the Company and the Trustee if there be furnished to them such security or
indemnity as they may require to save each of them and any Paying Agent
harmless. If thereafter the Holder of such Bearer Security shall surrender to
the Trustee or any Paying Agent any such missing interest coupon in respect of
which a deduction shall have been made from the Redemption Price, such Holder
shall be entitled to receive the amount so deducted; provided, however, that
interest represented by interest coupons shall be payable only at an office or
agency located outside of the United States (except as otherwise provided
pursuant to Section 9.2) and, unless otherwise specified as contemplated by
Section 3.1, only upon presentation and surrender of those interest coupons.

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

                  Section 11.7. Securities Redeemed in Part. Upon surrender of a
Security that is redeemed in part at any Place of Payment therefor (with, if the
Company or the Trustee so required, 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 or her attorney duly authorized in writing), the
Company shall execute and the Trustee shall authenticate and deliver to the
Holder of that Security, without service charge, a new Security or Securities of
the same series,


                                       85
<PAGE>   94
having the same form, terms and Stated Maturity, in any authorized denomination
equal in aggregate principal amount to the unredeemed portion of the principal
amount of the Security surrendered.


                                   ARTICLE 12

                                  SINKING FUNDS

                  Section 12.1. Applicability of Article. The provisions of this
Article shall be applicable to any sinking fund for the retirement of Securities
of a series except as otherwise specified as contemplated by Section 3.1 for
Securities of such series.

                  The minimum amount of any sinking fund payment provided for by
the terms of Securities of any series is herein referred to as a "mandatory
sinking fund payment," and any payment in excess of such minimum amount provided
for by the terms of Securities of any series is herein referred to as an
"optional sinking fund payment." If provided for by the terms of Securities of
any series, the cash amount of any sinking fund payment may be subject to
reduction as provided in Section 12.2. Each sinking fund payment shall be
applied to the redemption of Securities of any series as provided for by the
terms of Securities of such series.

                  Section 12.2. Satisfaction of Sinking Fund Payments with
Securities. The Company (i) may deliver Outstanding Securities of a series
(other than any previously called for redemption) together, in the case of
Bearer Securities of such series, with all unmatured interest coupons
appertaining thereto and (ii) may apply as a credit Securities of a series which
have been (x) redeemed either at the election of the Company pursuant to the
terms of such Securities or through the application of permitted optional
sinking fund payments pursuant to the terms of such Securities, (y) converted or
exchanged pursuant to Article 14 or (z) previously delivered to the Trustee and
cancelled without reissuance pursuant to Section 3.9, in each case in
satisfaction of all or any part of any sinking fund payment with respect to the
Securities of such series required to be made pursuant to the terms of such
Securities as provided for by the terms of such series; provided that such
Securities have not been previously so credited. Such Securities shall be
received and credited for such purpose by the Trustee at the Redemption Price
specified in such Securities for redemption through operation of the sinking
fund and the amount of such sinking fund payment shall be reduced accordingly.


                                       86
<PAGE>   95
                  Section 12.3. Redemption of Securities for Sinking Fund. Not
less than 45 days prior to each sinking fund payment date for any series of
Securities, the Company will deliver to the Trustee an Officers' Certificate
specifying the amount of the next ensuing sinking fund payment for that series
pursuant to the terms of that series, the portion thereof, if any, which is to
be satisfied by payment of cash and the portion thereof, if any, which is to be
satisfied by delivering and crediting Securities of that series pursuant to
Section 12.2 and stating the basis for such credit and that such Securities have
not been previously so credited, and will also deliver to the Trustee any
Securities to be so delivered. Not less than 30 days before each such sinking
fund payment date the Trustee shall select the Securities to be redeemed upon
such sinking fund payment date in the manner specified in Section 11.3 and cause
notice of the redemption thereof to be given in the name of and at the expense
of the Company in the manner provided in Section 11.4. Such notice having been
duly given, the redemption of such Securities shall be made upon the terms and
in the manner stated in Sections 11.6 and 11.7.

                                   ARTICLE 13

                    MEETINGS OF HOLDERS OF BEARER SECURITIES

                  Section 13.1. Purposes for Which Meetings May Be Called. A
meeting of Holders of Securities of any series issuable as Bearer Securities may
be called at any time and from time to time pursuant to this Article to make,
give or take any request, demand, authorization, direction, notice, consent,
election, waiver or other action provided by this Indenture to be made, given or
taken by Holders of Securities of such series.

                  Section 13.2. Call, Notice and Place of Meetings. (a) The
Trustee may at any time call a meeting of Holders of Securities of any series
issuable as Bearer Securities for any purpose specified in Section 13.1, to be
held at such time and at such place in The City of New York or in such other
place as may be acceptable to the Company. Notice of every meeting of Holders of
Securities, setting forth the time and the place of such meeting and in general
terms the action proposed to be taken at such meeting, shall be given, in the
manner provided in Section 1.6, not less than 21 nor more than 180 days prior to
the date fixed for the meeting.

                  (b) In case at any time the Company, pursuant to a Board
Resolution, or the Holders of at least 33 1/3% in principal amount of the
Outstanding Securities of any series shall have requested the Trustee to call a
meeting of the Holders of Securities of such series for any purpose specified in
Section 13.1, by written request setting forth in reasonable detail the action


                                       87
<PAGE>   96
proposed to be taken at the meeting, and the Trustee shall not have made the
first publication of the notice of such meeting within 21 days after receipt of
such request or shall not thereafter proceed to cause the meeting to be held as
provided herein, then the Company or the Holders of Securities of such series in
the amount specified, as the case may be, may determine the time and the place
in The City of New York or such other place as may be acceptable to the Company
for such meeting and may call such meeting for such purposes by giving notice
thereof as provided in paragraph (a) of this Section.

                  Section 13.3. Persons Entitled to Vote at Meetings. To be
entitled to vote at any meeting of Holders of Securities of any series issuable
as Bearer Securities, a Person shall be (a) a Holder of one or more Outstanding
Securities of such series, or (b) a Person appointed by an instrument in writing
as proxy for a Holder or Holders of one or more Outstanding Securities of such
series by such Holder or Holders. The only Persons who shall be entitled to be
present or to speak at any meeting of Holders shall be the Persons entitled to
vote at such meeting and their counsel, any representatives of the Trustee and
its counsel and any representatives of the Company and its counsel.

                  Section 13.4. Quorum; Action. The Persons entitled to vote a
majority in principal amount of the Outstanding Securities of the applicable
series shall constitute a quorum. In the absence of a quorum within 30 minutes
of the time appointed for any such meeting, the meeting shall, if convened at
the request of Holders of Securities of such series, be dissolved. In any other
case the meeting may be adjourned for a period of not less than 10 days as
determined by the chairman of the meeting prior to the adjournment of such
meeting. In the absence of a quorum at any such adjourned meeting, such
adjourned meeting may be further adjourned for a period not less than 10 days as
determined by the chairman of the meeting prior to the adjournment of such
adjourned meeting. Notice of the reconvening of any such adjourned meeting shall
be given as provided in Section 13.2(a), except that such notice need be given
only once not less than five days prior to the date on which the meeting is
scheduled to be reconvened.

                  At the reconvening of any meeting adjourned for a lack of a
quorum pursuant to the preceding paragraph, the Persons entitled to vote 25% in
principal amount of the Outstanding Securities of the applicable series at the
time shall constitute a quorum for the taking of any action set forth in the
notice of the original meeting. Notice of the reconvening of a meeting adjourned
for lack of a quorum shall state expressly the percentage of the principal
amount of the Outstanding Securities of such series which shall constitute a
quorum.


                                       88
<PAGE>   97
                  At a meeting or an adjourned meeting duly reconvened and at
which a quorum is present as aforesaid, any resolution and all matters (except
as limited by the proviso to Section 8.2) shall be effectively passed and
decided if passed or decided by the Persons entitled to vote not less than the
lesser of (i) a majority in principal amount of Outstanding Securities of the
applicable series and (ii) 66 2/3% in principal amount of Outstanding Securities
of such series represented and voting at such meeting; provided, however, that
any resolution with respect to any request, demand, authorization, direction,
notice, consent, election, waiver or other Act which this Indenture expressly
provides may be made, given or taken by the Holders of a specified percentage,
which is less than a majority, in principal amount of the Outstanding Securities
of a series may be adopted at a meeting or an adjourned meeting duly reconvened
and at which a quorum is present as aforesaid by the affirmative vote of the
lesser of (i) the Holders of such specified percentage in principal amount of
the Outstanding Securities of such series and (ii) a majority in principal
amount of Outstanding Securities of such series represented and voting at such
meeting or adjourned meeting.

                  Any resolution passed or decisions taken at any meeting of
Holders of Securities of any series issuable as Bearer Securities duly held in
accordance with this Section shall be binding on all the Holders of Securities
of such series and interest coupons, whether or not present or represented at
the meeting.

                  In the event that any meeting shall be adjourned for lack of a
quorum or that, at any meeting at which a quorum is present, any proposed
resolution or decision shall not be passed or taken because the Holders of the
percentage of Outstanding Securities of any series issuable as Bearer Securities
needed to approve such resolution or decision did not vote in favor of such
resolution or decision, the principal amount of Outstanding Securities of such
series represented at such meeting and voting in favor of such resolution or
decision may be counted for purposes of calculating whether the consent of the
Holders of the percentage of Outstanding Securities of such series needed in
order to make, give or take any request, demand, authorization, direction,
notice, consent, election, waiver or other action has been obtained, and such
vote shall constitute the consent thereto of such Holders.

                  Section 13.5. Determination of Voting Rights; Conduct and
Adjournment of Meetings. (a) Notwithstanding any other provisions of this
Indenture, the Trustee may make such reasonable regulations as it may deem
advisable for any meeting of Holders of Securities of any series issuable as
Bearer Securities in regard to proof of the holding of Securities of such series
and of the appointment of proxies and in regard to the appointment and duties of
inspectors


                                       89
<PAGE>   98
of votes, the submission and examination of proxies, certificates and other
evidence of the right to vote, and such other matters concerning the conduct of
the meeting as it shall deem appropriate. Except as otherwise permitted or
required by any such regulations, the holding of Securities of a series issuable
as Bearer Securities shall be proved in the manner specified in Section 1.4 and
the appointment of any proxy shall be provided in the manner specified in
Section 1.4 or by having the signature of the Person executing the proxy
witnessed or guaranteed by any trust company, bank or banker authorized by
Section 1.4 to certify to the holding of Bearer Securities. Such regulations may
provide that written instruments appointing proxies, regular on their face, may
be presumed valid and genuine without the proof specified in Section 1.4 or
other proof.

                  (b) The Trustee shall, by an instrument in writing, appoint a
temporary chairman (which may be a Responsible Officer of the Trustee) of the
meeting, unless the meeting shall have been called by the Company or by Holders
of Securities of a series as provided in Section 13.2(b), in which case the
Company or the Holders of Securities of such series calling the meeting, as the
case may be, shall in like manner appoint a temporary chairman. A permanent
chairman and a permanent secretary of the meeting shall be elected by vote of
the Persons entitled to vote a majority in principal amount of the Outstanding
Securities of such series represented at the meeting.

                  (c) At any meeting each Holder of a Security or proxy shall be
entitled to one vote for each U.S. $5,000 principal amount of Securities held or
represented by him or her; provided, however, that no vote shall be cast or
counted at any meeting in respect of any Security challenged as not Outstanding
and ruled by the chairman of the meeting to be not Outstanding. The chairman of
the meeting shall have no right to vote, except as a Holder of a Security or
proxy.

                  (d) Any meeting of Holders of Securities of a series issuable
as Bearer Securities duly called pursuant to Section 13.2 at which a quorum is
present may be adjourned from time to time by Persons entitled to vote a
majority in principal amount of the Outstanding Securities of such series
represented at the meeting, and the meeting may be held as so adjourned without
further notice.

                  Section 13.6. Counting Votes and Recording Action of Meetings.
The vote upon any resolution submitted to any meeting of Holders of Securities
of any series issuable as Bearer Securities shall be by written ballots on which
shall be subscribed the signatures of the Holders of Securities of such series
or of their representatives by proxy and the principal amounts and serial
numbers of the Outstanding Securities held or represented by them. The permanent
chairman of


                                       90
<PAGE>   99
the meeting shall appoint an inspector of votes who shall count all votes cast
at the meeting for or against any resolution and who shall make and file with
the secretary of the meeting its verified written report of all votes cast at
the meeting. A record of the proceedings of each meeting of Holders of
Securities shall be prepared by the applicable secretary of the meeting and
there shall be attached to said record the original report of the inspector of
votes on any vote by ballot taken thereat and affidavits by one or more Persons
having knowledge of the facts setting forth a copy of the notice of the meeting
and showing that said notice was given as provided in Section 13.2 and, if
applicable, Section 13.4. At least two copies of such record shall be signed and
verified by the affidavits of the permanent chairman and secretary of the
meeting and one copy thereof shall be delivered to the Company and the other to
the Trustee to be preserved by the Trustee, the latter to have attached thereto
the ballots voted at the meeting. Any record so signed and verified shall be
conclusive evidence of the matters therein stated.

                      CONVERSION OR EXCHANGE OF SECURITIES

                  Section 14.1. Applicability of Article. (a) The provisions of
this Article 14 shall be applicable to the Securities of any series which are

issuance of such Equity Securities upon the conversion or exchange of such

Company at the office or agency maintained for that purpose pursuant to Section
9.2, accompanied by written notice to the Company that the Holder elects to
convert or exchange such Security or a specified portion thereof. Such notice
shall also state, if different from the name and address of such Holder, the
name or names (with address) in which the certificate or certificates for Equity
Securities which shall be issuable on such conversion or exchange shall be
issued. Registered Securities


                                       91
<PAGE>   100
surrendered for conversion or exchange shall (if so required by the Company or
the Trustee) be duly endorsed by or accompanied by instruments of transfer in
forms satisfactory to the Company and the Trustee duly executed by the
registered Holder or its attorney duly authorized in writing.

                  (b) Registered Securities so surrendered for conversion or
exchange during the period from the close of business on any Regular Record Date
to the opening of business on the corresponding Interest Payment Date (excluding
Securities or portions thereof called for redemption during such period) shall
also be accompanied by payment in funds acceptable to the Company of an amount
equal to the interest payable on such Interest Payment Date on the principal
amount of such Security then being converted or exchanged, and such interest
shall be payable to such registered Holder on such Interest Payment Date
notwithstanding the conversion or exchange of such Security, subject to the
provisions of Section 3.7 relating to the payment of Defaulted Interest by the
Company.

                  (c) As promptly as practicable after the receipt of such
notice and of any payment required pursuant to a Board Resolution and, subject
to Section 3.3, set forth, or determined in the manner provided, in an Officers'
Certificate, or established in one or more indentures supplemental hereto
setting forth the terms of such series of Security, and the surrender of such
Security in accordance with such reasonable regulations as the Company may
prescribe, the Company shall issue and shall deliver, at the office or agency at
which such Security is surrendered, to such Holder or on its written order, a
certificate or certificates for the number of Equity Securities issuable upon
the conversion or exchange of such Security (or specified portion thereof), in
accordance with the provisions of such Board Resolution, Officers' Certificate
or supplemental indenture, and cash as provided therein in respect of any
fractional share of such Equity Security otherwise issuable upon such conversion
or exchange.

                  (d) Such conversion or exchange shall be deemed to have been
effected immediately prior to the close of business on the date on which such
notice and such payment, if required, shall have been received in proper order
for conversion or exchange by the Company and such Security shall have been
surrendered as aforesaid and at such time the rights of the Holder of such
Security as such Security Holder shall cease and the person or persons in whose
name or names any certificate or certificates for Equity Securities of the
Company shall be issuable upon such conversion or exchange shall be deemed to
have become the Holder or Holders of record of the Equity Securities represented
thereby. Except as set forth above and subject to paragraph (d) of Section 3.7,
no payment or

                                       92
<PAGE>   101
adjustment shall be made upon any conversion or exchange on account of any
interest accrued on the Securities surrendered for conversion or exchange, or on
account of any dividends on the Equity Securities of the Company issued upon
such conversion or exchange if the record date for the payment of such dividends
occurs prior to or on the date on which such conversion or exchange shall be
deemed to have been effected.

                  In the case of any Security which is converted or exchanged in
part only, upon such conversion or exchange the Company shall execute and the
Trustee shall authenticate and deliver to or on the order of the Holder thereof,
at the expense of the Company, a new Security or Securities of the same series,
of authorized denominations, in aggregate principal amount equal to the
unconverted or unexchanged portion of such Security.

                  Section 14.3. No Fractional Equity Securities. No fractional
Equity Security of the Company shall be issued upon conversions or exchanges of
Securities of any series. If more than one Security shall be surrendered for
conversion or exchange at one time by the same Holder, the number of full shares
of the Equity Security which shall be issuable upon conversion or exchange shall
be computed on the basis of the aggregate principal amount of the Securities (or
specified portions thereof to the extent permitted hereby) so surrendered. If,
except for the provisions of this Section 14.3, any Holder of a Security or
Securities would be entitled to a fractional share of any Equity Security of the
Company upon the conversion or exchange of such Security or Securities, or
specified portions thereof, the Company shall pay to such Holder an amount in
cash equal to the current market value of such fractional share computed, (i) if
such Equity Security is listed or admitted to unlisted trading privileges on a
national securities exchange, on the basis of the last reported sale price
regular way on the principal exchange where such Equity Security is listed or
admitted, on the last trading day prior to the date of conversion or exchange
upon which such a sale shall have been effected, (ii) if such Equity Security is
not at the time so listed or admitted on a national securities exchange but is
quoted on the National Market System of the National Association of Securities
Dealers, Inc. ("NASDAQ"), on the basis of the average of the bid and asked
prices of such Equity Security on NASDAQ on the last trading day prior to the
date of conversion or exchange, (iii) if such Equity Security is not at the time
so listed or admitted to unlisted trading privileges on a national securities
exchange or quoted on NASDAQ, on the basis of the average of the bid and asked
prices of such Equity Security in the over-the- counter market, on the last
trading day prior to the date of conversion or exchange, as reported by the
National Quotation Bureau Incorporated or similar organization if the National
Quotation Bureau Incorporated is no longer reporting such





                                       93
<PAGE>   102
information, or (iv) in accordance with the terms of the supplemental indenture
or Board Resolutions setting the terms of the Securities of such series. For
purposes of this Section, "trading day" shall mean each Monday, Tuesday,
Wednesday, Thursday and Friday other than any day on which the applicable Equity
Security is not traded or quoted on a national securities exchange, or if the
applicable Equity Security is not traded or quoted on a national securities
exchange, on NASDAQ or the principal exchange or market on which the applicable
Equity Security is traded or quoted.

                  Section 14.4. Adjustment of Conversion or Exchange Price;
Consolidation or Merger. The conversion or exchange price of Securities of any
series that is convertible or exchangeable into an Equity Security of the
Company shall be adjusted for any stock dividends, stock splits,
reclassification, combinations or similar transactions, and the securities,
assets or other property into or for which such Securities may be converted or
exchanged as a result of any consolidation, merger, combination or similar
transaction shall be determined, in accordance with the terms of the
supplemental indenture or Board Resolutions setting the terms of the Securities
of such series.

                  Whenever the conversion or exchange price is adjusted, the
Company shall compute the adjusted conversion or exchange price in accordance
with the terms of the applicable Board Resolution or supplemental indenture and
shall prepare an Officers' Certificate setting forth the adjusted conversion or
exchange price and showing in reasonable detail the facts upon which such
adjustment is based. Whenever the securities, assets or other property into or
for which Securities of any series may be converted or exchanged are changed as
a result of any consolidation, merger or similar transaction, the Company shall
determine the nature and amount of such securities, assets or other property in
accordance with the terms of the applicable Board Resolution or supplemental
indenture and shall prepare an Officer's Certificate describing such securities,
assets or other property and stating the amount of such securities, assets or
other property into or for which such Securities have become convertible or
exchangeable. Such certificates shall forthwith be filed at each office or
agency maintained for the purpose of conversion or exchange of Securities
pursuant to Section 9.2 and, if different, with the Trustee. The Company shall
forthwith cause a notice setting forth the adjusted conversion or exchange price
or describing such securities, assets or other property, as applicable, to be
mailed, first class postage prepaid, to each Holder of Registered Securities of
such series at its address appearing on the Register and to any conversion or
exchange agent other than the Trustee.

                  Section 14.5. Notice of Certain Corporate Actions. If any
series of Securities which are directly or indirectly convertible or
exchangeable for any Equity Securities are Outstanding, in case:

                           (a) the Company shall declare a dividend (or any
                  other distribution) on any class of such Equity Securities
                  payable otherwise than in cash out of its retained earnings
                  (other than a dividend for which approval of any stockholder
                  of the Company is required); or

                           (b) the Company shall authorize the granting to the
                  holders of any class of such Equity Securities of rights,
                  options or warrants to subscribe for or purchase any shares of
                  capital stock of any class or of any other rights (other than
                  any such grant for which approval of any stockholder of the
                  Company is required); or

                           (c) of any reclassification of any class of such
                  Equity Securities (other than a subdivision or combination of
                  its outstanding Equity Securities, or of any consolidation,
                  merger or share exchange to which the Company is a party and
                  for which approval of any stockholder of the Company is
                  required), or of the sale of all or substantially all of the
                  assets of the Company; or

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

then the Company shall cause to be filed with the Trustee, and shall cause to be
mailed to all Holders at their addresses as they shall appear in the Register,
at least 15 days (or 10 days in any case specified in clause (a) or (b) above)
prior to the applicable record date hereinafter specified, a notice stating (i)
the date on which a record is to be taken for the purpose of such dividend,
distribution, rights, options or warrants, or, if a record is not to be taken,
the date as of which the Holders of such Equity Securities of record to be
entitled to such dividend, distribution, rights, options or warrants are to be
determined, or (ii) the date on which such reclassification, consolidation,
merger, share exchange, sale, dissolution, liquidation or winding up is expected
to become effective, and the date as of which it is expected that holders of
such Equity Securities of record shall be entitled to exchange such Equity
Securities for securities, cash or other property deliverable upon such
reclassification, consolidation, merger, share exchange, sale, dissolution,
liquidation or winding up. If at any time the Trustee shall not be the


                                       95
<PAGE>   104
conversion or exchange agent, a copy of such notice shall also forthwith be
filed by the Company with the Trustee.

                  Section 14.6. Reservation of Equity Securities. The Company
shall at all times reserve and keep available, free from preemptive rights, out
of its authorized but unissued Equity Securities, for the purpose of effecting
the conversion or exchange of Securities, the full number of Equity Securities
of the Company then issuable upon the conversion or exchange of all Outstanding
Securities of any series that has conversion or exchange rights.

                  Section 14.7. Payment of Certain Taxes Upon Conversion or
Exchange. The Company will pay any and all taxes that may be payable in respect
of the issue or delivery of its Equity Securities on conversion or exchange of
Securities pursuant hereto. The Company shall not, however, be required to pay
any tax which may be payable in respect of any transfer involved in the issue
and delivery of its Equity Securities in a name other than that of the Holder of
the Security or Securities to be converted or exchanged, and no such issue or
delivery shall be made unless and until the Person requesting such issue has
paid to the Company the amount of any such tax, or has established, to the
satisfaction of the Company, that such tax has been paid.

                  Section 14.8. Duties of Trustee Regarding Conversion or
Exchange. Neither the Trustee nor any conversion or exchange agent shall at any
time be under any duty or responsibility to any Holder of Securities of any
series that is convertible or exchangeable into Equity Securities of the Company
to determine whether any facts exist which may require any adjustment of the
conversion or exchange price, or with respect to the nature or extent of any
such adjustment when made, or with respect to the method employed, whether
herein or in any supplemental indenture, any resolutions of the Board of
Directors or written instrument executed by one or more officers of the Company
provided to be employed in making the same. Neither the Trustee nor any
conversion or exchange agent shall be accountable with respect to the validity
or value (or the kind or amount) of any Equity Securities of the Company, or of
any securities or property, which may at any time be issued or delivered upon
the conversion or exchange of any Securities and neither the Trustee nor any
conversion or exchange agent makes any representation with respect thereto.
Subject to the provisions of Section 6.1, neither the Trustee nor any conversion
or exchange agent shall be responsible for any failure of the Company to issue,
transfer or deliver any of its Equity Securities or stock certificates or other
securities or property upon the surrender of any Security for the purpose of
conversion or exchange or to comply with any of the covenants of the Company
contained in this Article 14 or in the

                                       96
<PAGE>   105
applicable supplemental indenture, resolutions of the Board of Directors or
written instrument executed by one or more duly authorized officers of the
Company.

                  Section 14.9. Repayment of Certain Funds Upon Conversion or
Exchange. Any funds which at any time have been deposited by the Company or on
its behalf with the Trustee or any Paying Agent for the purpose of paying the
principal of, and premium, if any, and interest, if any, on any of the
Securities (including funds deposited for any sinking fund referred to in
Article 12 hereof) and which shall not be required for such purposes because of
the conversion or exchange of such Securities as provided in this Article 14
shall after such conversion or exchange be repaid to the Company by the Trustee
upon the Company's written request by Company Request.

                           SUBORDINATION OF SECURITIES

                  Section 15.1. Securities Subordinate to Senior Debt. The
Company covenants and agrees, and each Holder of a Security, by his acceptance
thereof, likewise covenants and agrees, that, to the extent and in the manner
hereinafter set forth in this Article (subject to the provisions of Article 4),
the payment of the principal of (and premium, if any) and interest on the
Securities and any other obligations in respect of the Securities (including any
obligation to repurchase Securities) are hereby expressly made subordinate and
subject in right of payment to the prior payment in full of all Senior Debt of
the Company.

                  Section 15.2. Payment Over of Proceeds Upon Dissolution, Etc.
In the event of (a) any insolvency or bankruptcy case or proceeding, or any
receivership, liquidation, reorganization or other similar case or proceeding in
connection therewith, relative to the Company or to its creditors, as such, or
to its assets, or (b) any liquidation, dissolution or other winding up of the
Company, whether voluntary or involuntary and whether or not involving
insolvency or bankruptcy, or (c) any assignment for the benefit of creditors or
any other marshalling of assets and liabilities of the Company, then and in any
such event specified in (a), (b) or (c) above (each such event, if any, herein
sometimes referred to as a "Company Proceeding") the holders of all Senior Debt
of the Company shall first be entitled to receive payment in full of all amounts
due or to become due on or in respect of all such Senior Debt, or provision
shall be made for such payment in cash or cash equivalents or otherwise in a
manner satisfactory to the holders of such Senior Debt, before the Holders of
the Securities are entitled to


                                       97
<PAGE>   106
receive any payment or distribution of any kind or character from the Company,
whether in cash, property or securities (including any payment or distribution
which may be payable or deliverable by reason of the payment of any other Debt
of the Company subordinated to the payment of the Securities on account of
principal of (or premium, if any) or interest on or other obligations in respect
of the Securities or on account of any purchase or other acquisition of
Securities by the Company or any Subsidiary of the Company (all such payments,
distributions, purchases and acquisitions herein referred to, individually and
collectively, as a "Company Securities Payment"), and to that end the holders of
Senior Debt of the Company shall be entitled to receive, for application to the
payment thereof, any Company Securities Payment which may be payable or
deliverable in respect of the Securities in any such Company Proceeding.

                  In the event that, notwithstanding the foregoing provisions of
this Section, the Trustee or the Holder of any Security shall have received any
Securities Payment before all Senior Debt the Company is paid in full or payment
thereof provided for in cash or cash equivalents or otherwise in a manner
satisfactory to the holders of such Senior Debt, then and in such event such
Securities Payment shall be paid over or delivered forthwith to the holders of
Senior Debt for application to the payment of such Senior Debt remaining unpaid,
to the extent necessary to pay such Senior Debt in full, after giving effect to
any concurrent payment or distribution to or for the holders of such Senior
Debt.

                  The consolidation of the Company with, or the merger of the
Company into, another Person or the liquidation or dissolution of the Company
following the conveyance or transfer of all or substantially all of its
properties and assets as an entirety to another Person upon the terms and
conditions set forth in Article 7 shall not be deemed a Proceeding for the
purposes of this Section if the Person formed by such consolidation or into
which the Company is merged or the Person which acquires by conveyance or
transfer such properties and assets as an entirety, as the case may be, shall,
as a part of such consolidation, merger, conveyance or transfer, comply with the
conditions set forth in Article 7.

                  Section 15.3. No Payment When Senior Debt in Default. In the
event that any Senior Payment Default (as defined below) shall have occurred and
be continuing, then no Company Securities Payment shall be made unless and until
such Senior Payment Default shall have been cured or waived or shall have ceased
to exist or all amounts then due and payable in respect of Senior Debt of the
Company shall have been paid in full, or provision shall have been made for such
payment in cash or otherwise in a manner satisfactory to the holders of such
Senior Debt. "Senior Payment Default" means (i) any default in the payment of
principal


                                       98
<PAGE>   107
of (or premium, if any) or interest on any Senior Debt of the Company and (ii)
any event of default with respect to Senior Debt of the Company which has
resulted in such Senior Debt becoming or being declared due and payable prior to
the date on which it would otherwise have become due and payable.

                  In the event that any Senior Nonmonetary Default (as defined
below) shall have occurred and be continuing, then, upon the receipt by the
Company and the Trustee of written notice of such Senior Nonmonetary Default
from any holder of Senior Debt of the Company with a principal amount in excess
of $50,000,000, no Company Securities Payment shall be made during the period
(the "Payment Blockage Period") commencing on the date of such receipt of such
written notice and ending on the earlier of (i) the date on which such Senior
Nonmonetary Default shall have been cured or waived or shall have ceased to
exist and any acceleration of Senior Debt of the Company shall have been
rescinded or annulled or the Senior Debt of the Company to which such Senior
Nonmonetary Default relates shall have been discharged or (ii) the 179th day
after the date of such receipt of such written notice. No more than one Payment
Blockage Period may be commenced with respect to the Securities during any
consecutive 360-day period. For all purposes of this paragraph, no Senior
Nonmonetary Default that existed or was continuing on the date of commencement
of any Payment Blockage Period shall be, or be made, the basis for the
commencement of a subsequent Payment Blockage Period whether or not within a
period of 360 consecutive days by holders of Senior Debt of the Company or their
representatives unless such Senior Nonmonetary Default shall have been cured for
a period of not less than 90 consecutive days. "Senior Nonmonetary Default"
means the occurrence or existence and continuance of any event of default, or of
any event which, after notice or lapse of time (or both), would become an event
of default, under the terms of any instrument pursuant to which any Senior Debt
of the Company is outstanding, permitting (after notice or lapse of time or
both) one or more holders of such Senior Debt (or a trustee or agent on behalf
of the holders thereof) to declare such Senior Debt due and payable prior to the
date on which it would otherwise become due and payable, other than a Senior
Payment Default.

                  In the event that, notwithstanding the foregoing, the Company
shall make any Company Securities Payment to the Trustee or any Holder
prohibited by the foregoing provisions of this Section, then and in such event
such Company Securities Payment shall be paid over and delivered forthwith to
the holders of the Senior Debt of the Company.

                  The provisions of this Section shall not apply to any Company
Securities Payment with respect to which Section 15.2 would be applicable.

<PAGE>   108
                  Section 15.4. Certain Payments Permitted. Nothing contained in
this Article or elsewhere in this Indenture or in any of the Securities shall
prevent the Company, at any time except during the pendency of any Proceeding
referred to in Section 15.2 or under the conditions described in Section 15.3,
from making Company Securities Payments.

                  Section 15.5. Subrogation to Rights of Holders of Senior Debt.
Subject to the payment in full in cash of all amounts due or to become due on or
in respect of Senior Debt of the Company or the provision for such payment in
cash or cash equivalents or otherwise in a manner satisfactory to the holders of
such Senior Debt, the Holders of the Securities shall be subrogated to the
rights of the holders of such Senior Debt to receive payments and distributions
of cash, property and securities applicable to such Senior Debt until the
principal of (and premium, if any) and interest on the Securities shall be paid
in full. For purposes of such subrogation, no payments or distributions to the
holders of the Senior Debt of the Company of any cash, property or securities to
which the Holders of the Securities or the Trustee would be entitled except for
the provisions of this Article, and no payments over pursuant to the provisions
of this Article to the holders of Senior Debt of the Company by Holders of the
Securities or the Trustee, shall, as among the Company, its creditors other than
holders of Senior Debt and the Holders of the Securities, be deemed to be a
payment or distribution by the Company to or on account of the Senior Debt of
the Company.

                  Section 15.6. Provisions Solely to Define Relative Rights. The
provisions of this Article are and are intended solely for the purpose of
defining the relative rights of the Holders on the one hand and the holders of
Senior Debt on the other hand. Nothing contained in this Article or elsewhere in
this Indenture or in the Securities is intended to or shall (a) impair, as among
the Company, its creditors other than holders of Senior Debt and the Holders of
the Securities the obligation of the Company which is absolute and unconditional
(and which, subject to the rights under this Article of the holders of Senior
Debt, is intended to rank equally with all other general obligations of the
Company), to pay to the Holders of the Securities the principal of (and premium,
if any) and interest on the Securities as and when the same shall become due and
payable in accordance with their terms; or (b) affect the relative rights
against the Company of the Holders of the Securities and creditors of the
Company other than the holders of Senior Debt; or (c) prevent the Trustee or the
Holder of any Security from exercising all remedies otherwise permitted by
applicable law upon default under this Indenture, subject to the rights, if any,
under this Article of the holders of Senior Debt to

                                      100
<PAGE>   109
receive cash, property and securities otherwise payable or deliverable to the
Trustee or such Holder.

                  Section 15.7. Trustee to Effectuate Subordination. Each Holder
of a Security by his acceptance thereof authorizes and directs the Trustee on
his behalf to take such action as may be necessary or appropriate to effectuate
the subordination provided in this Article and appoints the Trustee his
attorney-in-fact for any and all such purposes.

                  Section 15.8. No Waiver of Subordination Provisions. No right
of any present or future holder of any Senior Debt 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 any such holder may have or be otherwise charged with.

                  Without in any way limiting the generality of the foregoing
paragraph, the holders of Senior Debt may, at any time and from time to time,
without the consent of or notice to the Trustee or the Holders of the
Securities, without incurring responsibility to the Holders of the Securities
and without impairing or releasing the subordination provided in this Article or
the obligations hereunder of the Holders of the Securities to the holders of
Senior Debt, 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 or
increase, Senior Debt, or otherwise amend or supplement in any manner Senior
Debt or any instrument evidencing the same or any agreement under which Senior
Debt is outstanding; (ii) sell, exchange, release or otherwise deal with any
property pledged, mortgaged or otherwise securing Senior Debt; (iii) release any
Person liable in any manner for the collection of Senior Debt; and (iv) exercise
or refrain from exercising any rights against the Company and any other Person.

                  Section 15.9. Notice to Trustee. The Company shall give prompt
written notice to the Trustee of any fact known to the Company which would
prohibit the making of any payment to or by the Trustee in respect of the
Securities. Notwithstanding the provisions of this Article 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 to or
by the Trustee in respect of the Securities, unless and until the Trustee shall
have received written notice thereof from the Company or a holder of Senior Debt
or from any trustee therefor; and, prior to the receipt of any such written
notice, the Trustee, subject to


                                      101
<PAGE>   110
the provisions of Section 6.1, shall be entitled in all respects to assume that
no such facts exist, provided that nothing in this Section 15.9 shall impair the
subordination provisions of this Article Fourteen.

                  Subject to the provisions of Section 6.1, the Trustee shall be
entitled to rely on the delivery to it of a written notice by a Person
representing himself to be a holder of Senior Debt (or a trustee, representative
or agent therefor) to establish that such notice has been given by a holder of
Senior Debt (or a trustee, representative or agent therefor). 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 Debt to participate in
any payment or distribution pursuant to this Article, the Trustee may request
such Person to furnish evidence to the reasonable satisfaction of the Trustee as
to the amount of Senior Debt held by such Person, the extent to which such
Person is entitled to participate in such payment or distribution and any other
facts pertinent to the rights of such Person under this Article, 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 15.10. Reliance on Judicial Order or Certificate of
Liquidating Agent. Upon any payment or distribution of assets or securities of
the Company referred to in this Article, the Trustee, subject to the provisions
of Section 6.1, and the Holders of the Securities shall be entitled to rely upon
any order or decree entered by any court of competent jurisdiction in which such
Proceeding is pending, or a certificate of the trustee in bankruptcy, receiver,
liquidating trustee, custodian, assignee for the benefit of creditors, agent or
other Person making such payment or distribution, delivered to the Trustee or to
the Holders of Securities, for the purpose of ascertaining the Persons entitled
to participate in such payment or distribution, the holders of the Senior Debt
and other indebtedness of the Company, the amount thereof or payable thereon,
the amount or amounts paid or distributed thereon and all other facts pertinent
thereto or to this Article.

                  Section 15.11. Trustee Not Fiduciary for Holders of Senior
Debt. The Trustee shall not be deemed to owe any fiduciary duty to the holders

                  Section 15.12. Rights of Trustee as Holder of Senior Debt;
Preservation of Trustee's Rights. The Trustee in its individual capacity shall
be entitled to all the rights set forth in this Article with respect to any
Senior Debt which may at any time be held by it, to the same extent as any other
holder of Senior Debt, and nothing in this Indenture shall deprive the Trustee
of any of its rights as such holder.

                  Nothing in this Article shall apply to claims of, or payments
to, the Trustee under or pursuant to Section 6.7.

                  Section 15.13. Article Applicable to Paying Agents. In case at
any time any Paying Agent other than the Trustee shall have been appointed by
the Company and be then acting hereunder, the term "Trustee" as used in this
Article shall in such case (unless the context otherwise requires) be construed
as extending to and including such Paying Agent within its meaning as fully for
all intents and purposes as if such Paying Agent were named in this Article in
addition to or in place of the Trustee; provided, however, that Section 15.12
shall not apply to the Company or any Affiliate of the Company if it or such
Affiliate acts as Paying Agent.

                  Section 15.14. Defeasance of this Article 15. The
subordination of the Securities provided by this Article 15 is expressly made
subject to the provisions for defeasance or covenant defeasance in Article 4
and, anything herein to the contrary notwithstanding, upon the effectiveness of
any such defeasance or covenant defeasance, the Securities then Outstanding
relating thereto shall thereupon cease to be subordinated pursuant to this
Article 15.

                  (1) a statement that each individual signing such certificate
or opinion has read such condition or covenant and the definitions herein
relating thereto;

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

                  (3) a statement that, in the opinion of each such individual,
he or she has made such examination or investigation as is necessary to enable
him or her to express an informed opinion as to whether or not such condition or
covenant has been complied with; and

                  (4) a statement as to whether, in the opinion of each such
individual, such condition or covenant has been complied with.

                  Section 1.3. Form of Documents Delivered to Trustee. In any
case where several matters are required to be certified by, or covered by an
opinion of, any specified Person, it is not necessary that all such matters be
certified by, or covered by the opinion of, only one such Person, or that they
be so certified or covered by only one document, but one such Person may certify
or give an opinion with respect to some matters and one or more other such
Persons as to other matters, and any such Person may certify or give an opinion
as to such matters in one or several documents.

                  Any certificate or opinion of an officer of the Company may be
based, insofar as it relates to legal matters, upon a certificate or opinion of,
or representations by, counsel, unless such officer knows, or in the exercise of
reasonable care should know, that the certificate or opinion or representations
with respect to the matters upon which his or her certificate or opinion is
based are erroneous. Any such certificate or opinion or any Opinion of Counsel
may be based, insofar as it relates to factual matters, upon a certificate or
opinion of, or representations by, an officer or officers of the Company stating
that the information with respect to such factual matters is in the possession
of the Company, unless such officer or counsel knows, or in the exercise of
reasonable care should know, that the certificate or opinion or representations

accountants in the employ of the Company, unless such officer or counsel, as the
case may be, knows, or in the exercise of


                                       13
<PAGE>   22
reasonable care should know, that the certificate or opinion or representations
with respect to the accounting matters upon which his certificate, statement or
opinion is based are erroneous.

                  Where any Person is required to make, give or execute two or
more applications, requests, consents, certificates, statements, opinions or
other instruments under this Indenture, they may, but need not, be consolidated
and form one instrument.

                  Section 1.4. Acts of Holders. (a) Any request, demand,
authorization, direction, notice, consent, waiver or other action provided by
this Indenture to be given or taken by Holders may be embodied in and evidenced
by one or more instruments of substantially similar tenor signed (either
physically or by means of a facsimile or an electronic transmission, provided,
in the case of an electronic transmission, that it is transmitted through the
facilities of a Depositary) by such Holders in person or by agent or proxy duly
appointed in writing. If Securities of a series are issuable as Bearer
Securities, any request, demand, authorization, direction, notice, consent,
waiver or other action provided by this Indenture to be given or taken by
Holders of Securities of such series may, alternatively, be embodied in and
evidenced by the record of Holders of Securities of such series voting in favor
thereof pursuant to the third paragraph of Section 13.4, either in person or by
proxies duly appointed in writing, at any meeting of Holders of Securities of
such series duly called and held in accordance with the provisions of Article
13, or a combination of such instruments and any such record. Except as herein
otherwise expressly provided, such action shall become effective when such
instrument or instruments or record or both are received (either physically or
by means of a facsimile or an electronic transmission, provided, in the case of
an electronic transmission, that it is transmitted through the facilities of a
Depositary) by the Trustee and, where it is hereby expressly required, to the
Company. Such instrument or instruments and record (and the action embodied
therein and evidenced thereby) are herein sometimes referred to as the "Act" of
the Holders signing such instrument or instruments or, in the case of Holders of
Securities of a series issuable as Bearer Securities, so voting at such meeting.
The Company and the Trustee may assume that any Act of a Holder has not been
modified or revoked unless written notice to the contrary is received prior to
the time that the action to which such Act relates has become effective. Proof
of execution of any such instrument or of a writing appointing any such agent
shall be sufficient for any purpose of this Indenture and (subject to Section
315 of the Trust Indenture Act) conclusive in favor of the Trustee and the
Company, if made in the manner provided in this Section. The record of any
meeting of Holders of Securities issuable as Bearer Securities shall be proved
in the manner provided in Section 13.6.

                  (b) The fact and date of the execution by any Person of any
such instrument or writing and the authority of the Person executing the same
may be proved in any manner which the Trustee deems sufficient.


                                       14
<PAGE>   23
                  (c) The ownership of Bearer Securities may be proved by the
production of such Bearer Securities or by a certificate executed by any trust
company, bank, banker or other depository, wherever situated, if such
certificate shall be deemed by the Trustee to be satisfactory, showing that at
the date therein mentioned such Person had on deposit with such trust company,
bank, banker or other depository, or exhibited to it, the Bearer Securities
therein described; or such facts may be proved by the certificate or affidavit
of the Person holding such Bearer Securities, if such certificate or affidavit
is deemed by the Trustee to be satisfactory. The Trustee and the Company may
assume that such ownership of any Bearer Security continues until (i) another
such certificate or affidavit bearing a later date issued in respect of the same
Bearer Security is produced, (ii) such Bearer Security is produced to the
Trustee by some other Person, (iii) such Bearer Security is surrendered in
exchange for a Registered Security or (iv) such Bearer Security is no longer
Outstanding. The ownership of Bearer Securities may also be proved in any other
manner which the Trustee deems sufficient.

                  (d) The ownership of Registered Securities shall be proved by
the Register.

                  (e) Any request, demand, authorization, direction, notice,
consent, waiver or other Act of the Holder of any Security shall bind every
future Holder of the same Security and any interest coupons appertaining thereto
and the Holder of every Security or interest coupon 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 Act is made upon such Security
or interest coupon.

                  (f) If the Company shall solicit from the Holders any request,
demand, authorization, direction, notice, consent, waiver or other Act, the
Company may, at its option, by or pursuant to a Board Resolution, fix in advance
a record date for the determination of Holders of Registered Securities entitled
to give such request, demand, authorization, direction, notice, consent, waiver
or other Act, but the Company shall have no obligation to do so. Notwithstanding
Section 316(c) of the Trust Indenture Act, any such record date shall be the
record date specified in or pursuant to such Board Resolution, which shall be a
date not more than 30 days prior to the first solicitation of Holders generally
in connection therewith and no later than the date such first solicitation is
completed. If such a record date is fixed, such request, demand, authorization,
direction, notice, consent, waiver or other Act may be given before or after
such record date, but only the Holders of Registered Securities of record at the
close of business on such record date shall be deemed to be Holders for the
purposes of determining whether Holders of the requisite proportion of
Outstanding Securities have authorized or agreed or consented to such request,
demand, authorization, direction, notice, consent, waiver or other Act, and for
that purpose the Outstanding Securities shall be computed as of such


                                       15
<PAGE>   24
record date; provided that no such authorization, agreement or consent by the
Holders on such record date shall be deemed effective unless it shall become
effective pursuant to the provisions of this Indenture not later than six months
after the record date.

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

                  Section 1.5. Notices, Etc., to Trustee, Company and
Guarantors. 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,

                  (1) 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 Department, or at any other address previously furnished in
writing to the Holders or the Company by the Trustee, or, with respect to

provided) if in writing and mailed, first-class postage prepaid, to it addressed
to it at the address of the Company's principal office specified in the first
paragraph of this instrument or at any other address previously furnished in

Trustee, transmitted by facsimile transmission (confirmed by guaranteed
overnight courier) to the following facsimile number: (602) 423-9424 or to any
other facsimile number previously furnished in writing to the Trustee by the
Company.

                  Section 1.6. Notice to Holders; Waiver. Where this Indenture
provides for notice to Holders of any event, (i) if any of the Securities
affected by such event are Registered Securities, such notice to the Holders
thereof shall be sufficiently given (unless otherwise herein expressly provided)
if in writing and mailed, first-class postage prepaid, to each such Holder
affected by such event, at his or her address as it appears in the Register,
within the time prescribed for the giving of such notice, and (ii) if any of the
Securities affected by such event are Bearer Securities, notice to the Holders
thereof shall be sufficiently given (unless otherwise herein or in the terms of
such Bearer Securities expressly provided) if published once in an Authorized
Newspaper in New York, New



                                       16

contemplated by Section 3.1. Such notices shall be deemed to have been given on
the date of such mailing or publication.

                  In any case where notice to Holders is given by mail or by
publication, neither the failure to mail or publish such notice, nor any defect
in any notice so mailed or published, to any particular Holder shall affect the
sufficiency of such notice with respect to other Holders of Registered
Securities or of Bearer Securities. Any notice mailed to a Holder in the manner
herein prescribed shall be conclusively deemed to have been received by such
Holder, whether or not such Holder actually receives such notice.

                  If by reason of the suspension of regular mail service or by
reason of any other cause it shall be impracticable to give such notice as
provided above, then such notification as shall be made with the approval of the
Trustee shall constitute a sufficient notification for every purpose hereunder.
If it is impossible or, in the opinion of the Trustee, impracticable to give any
notice by publication in the manner herein required, then such publication in
lieu thereof as shall be made with the approval of the Trustee shall constitute
a sufficient publication of such notice.

                  Any request, demand, authorization, direction, notice, consent
or waiver required or permitted under this Indenture shall be in the English
language, except that any published notice may be in an official language of the
country of publication.

                  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 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 suspension of regular mail service or 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
sufficient notification for every purpose hereunder.

                  Section 1.7. Headings and Table of Contents. The Article and
Section headings herein and the Table of Contents are for convenience only and
shall not affect the construction hereof.

                  Section 1.8. Successor and Assigns. All covenants and
agreements in this Indenture by the Company or any Guarantor shall bind its
successors and assigns, whether so expressed or not.

                  Section 1.9. Separability. In case any provision of this
Indenture or the Securities or the Senior Guarantees 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 1.10. Benefits of Indenture. Nothing in this Indenture
or in the Securities or the Senior Guarantees, expressed or implied, shall give
to any Person, other than the parties hereto and their successors hereunder and
the Holders, any benefit or any legal or equitable right, remedy or claim under
this Indenture.

                  Section 1.11. Incorporators, Stockholders, Officers and
Directors of the Company Exempt from Individual Liability. No recourse under or
upon any obligation, covenant or agreement of or contained in this Indenture or
of or contained in any Security or interest coupon appertaining thereto, or for
any claim based thereon or otherwise in respect thereof, or because of any
indebtedness represented thereby, shall be had against any incorporator,
stockholder, officer or director, as such, past, present or future, of the
Company or any successor Person, either directly or through the Company or any
successor Person, whether by virtue of any constitution, statute or rule of law,
by the enforcement of any assessment or penalty, by any legal or equitable
proceeding or otherwise; it being expressly understood that all such liability
is hereby expressly waived and released as a condition of the acceptance of, and
as a part of the consideration for the execution of this Indenture and the
issuance of, the Securities and any interest coupons appertaining thereto.

                  Section 1.12. Governing Law; Conflict with Trust Indenture
Act. THIS INDENTURE, THE SECURITIES, THE SENIOR GUARANTEES ENDORSED THEREON AND
ANY INTEREST COUPONS APPERTAINING THERETO SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK. This Indenture is subject to
the Trust Indenture Act and if any provision hereof limits, qualifies or
conflicts with the Trust Indenture Act, the Trust Indenture Act shall control.
Whether or not this Indenture is required to be qualified under the Trust
Indenture Act, the provisions of the Trust Indenture Act required to be included
in an indenture in order for such indenture to be so qualified shall be deemed
to be included in this Indenture with the same effect as if such provisions were
set forth herein and any provisions hereof which may not be included in an
indenture which is so qualified shall be deemed to be deleted or modified to the
extent such provisions would be required to be deleted or modified in an
indenture so qualified.

                  Section 1.13. Legal Holidays. In any case where any Interest
Payment Date, Redemption Date, sinking fund payment date, Stated Maturity or
Maturity of any Security shall not be a Business Day at any Place of Payment,
then (notwithstanding any other provision of this Indenture or of any Security
or interest coupon or any Senior


                                       18
<PAGE>   27
Guarantee other than a provision in the Securities of any series which
specifically states that such provision shall apply in lieu of this Section),
payment of principal, premium, if any, or interest need not be made at such
Place of Payment on such date, but may be made on the next succeeding Business
Day at such Place of Payment with the same force and effect as if made on such
date; provided that no interest shall accrue on the amount so payable for the
period from and after such Interest Payment Date, Redemption Date, sinking fund
payment date, Stated Maturity or Maturity, as the case may be, if such amount is
so paid on the next succeeding Business Day.

                  Section 1.14. Moneys of Different Currencies to Be Segregated.
The Trustee shall segregate all moneys, funds and accounts held by the Trustee
hereunder in one currency from any moneys, funds and accounts held by the
Trustee hereunder in one currency from any moneys, funds or accounts in any
other currencies, notwithstanding any provision herein which would otherwise
permit the Trustee to commingle such amounts.

                  Section 1.15. Independence of Covenants. All covenants and
agreements in this Indenture shall be given independent effect so that if a
particular action or condition is not permitted by any such covenant, the fact
that it would be permitted by an exception to, or be otherwise within the
limitations of, another covenant shall not avoid the occurrence of a Default or
an Event of Default if such action is taken or condition exists.

                  Section 1.16. Counterparts. This Indenture may be executed in
any number of counterparts, each of which shall be an original, but such
counterparts shall together constitute but one and the same instrument.

and other variations as are required or permitted by this Indenture, and may
have such letters, numbers or other marks of identification and such legends or

any series are issued as permitted

<PAGE>   28
by Section 3.4, the form thereof also shall be established as provided in the
preceding sentence. If the forms of Securities and interest coupons, if any, and
Senior Guarantees of any series are established by, or by action taken pursuant

appropriate record of any such action taken pursuant thereto, including a copy
of the approved form of Securities or interest coupons, if any, and Senior
Guarantees shall be delivered to the Trustee at or prior to the delivery of the
Company Order contemplated by Section 3.3 for the authentication and delivery of

                                        as Trustee

                     Section 2.3 Form of Senior Guarantee.
    

                          SENIOR SUBORDINATED GUARANTEE
   
                  For value received, each of the Guarantors named (or deemed
herein to be named) below hereby jointly and severally unconditionally
guarantees, on a senior basis to the Holder of the Security upon which this
Senior Subordinated Guarantee is endorsed, and to the Trustee on behalf of such
Holder, the due and punctual payment of the principal of (and premium, if any)
and interest on such Security when and as the same shall become due and payable,
whether at the Stated Maturity, by acceleration, call for redemption, purchase
or otherwise, according to the terms thereof and of the Indenture referred to
therein. In case of the failure of the Company punctually to make any such
payment, each of the Guarantors hereby jointly and severally agrees to
    


                                       20
<PAGE>   29
cause such payment to be made punctually when and as the same shall become due
and payable, whether at the Stated Maturity or by acceleration, call for
redemption, purchase or otherwise, and as if such payment were made by the
Company.

                  The Senior Subordinated Guarantee of each Guarantor shall be
subordinated in right of payment to the Senior Debt of such Guarantor as
provided in the Indenture.

                  Each of the Guarantors hereby jointly and severally agrees
that its obligations hereunder shall be unconditional, irrespective of the
validity, regularity or enforceability of such Security or the Indenture, the
absence of any action to enforce the same, any creation, exchange, release or
non-perfection of any Lien on any collateral for, or any release or amendment or
waiver of any term of any other Guarantee of, or any consent to departure from
any requirement of any other Guarantee of, all or of any of the Securities, the
election by the Trustee or any of the Holders in any proceeding under Chapter 11
of the Bankruptcy Code of the application of Section 1111(b)(2) of the
Bankruptcy Code, any borrowing or grant of a security interest by the Company,
as debtor-in-possession, under Section 364 of the Bankruptcy Code, the
disallowance, under Section 502 of the Bankruptcy Code, of all or any portion of
the claims of the Trustee or any of the Holders for payment of any of the
Securities, any waiver or consent by the Holder of such Security or by the
Trustee or either of them with respect to any provisions thereof or of the
Indenture, the obtaining of any judgment against the Company or any action to
enforce the same or any other circumstances which might otherwise constitute a
legal or equitable discharge or defense of a Guarantor. Each of the Guarantors
hereby waives the benefits of diligence, presentment, demand of payment, any
requirement that the Trustee or any of the Holders protect, secure, perfect or
insure any security interest in or other Lien on any property subject thereto or
exhaust any right or take any action against the Company or any other Person or
any collateral, filing of claims with a court in the event of insolvency or
bankruptcy of the Company, any right to require a proceeding first against the
Company, protest or notice with respect to such Security or the indebtedness
evidenced thereby and all demands whatsoever, and covenants that this Senior
Subordinated Guarantee will not be discharged except by complete performance of
the obligations contained in such Security and in this Senior Subordinated
Guarantee. Each of the Guarantors hereby agrees that, in the event of a default
in payment of principal (or premium, if any) or interest on such Security,
whether at their Stated Maturity, by acceleration, call for redemption, purchase
or otherwise, legal proceedings may be instituted by the Trustee on behalf of,
or by, the Holder of such Security, subject to the terms and conditions set
forth in the Indenture, directly against each of the Guarantors to enforce this
Senior Subordinated Guarantee without first proceeding against the Company. Each
Guarantor agrees that if, after the occurrence and during the continuance of an
Event of Default, the Trustee or any of the Holders are prevented by applicable
law from exercising their respective rights to accelerate the maturity of the


                                       21
<PAGE>   30
Securities, to collect interest on the Securities, or to enforce or exercise any
other right or remedy with respect to the Securities, such Guarantor agrees to
pay to the Trustee for the account of the Holders, upon demand therefor, the
amount that would otherwise have been due and payable had such rights and
remedies been permitted to be exercised by the Trustee or any of the Holders.

                  No reference herein to the Indenture and no provision of this
Senior Subordinated Guarantee or of the Indenture shall alter or impair the
Senior Subordinated Guarantee of any Guarantor, which is absolute and
unconditional, of the due and punctual payment of the principal (and premium, if
any) and interest on the Security upon which this Senior Subordinated Guarantee
is endorsed.

                  Each Guarantor shall be subrogated to all rights of the Holder
of such Security against the Company in respect of any amounts paid by such
Guarantor on account of such Security pursuant to the provisions of its Senior
Subordinated Guarantee or the Indenture; provided, however, that such Guarantor
shall not be entitled to enforce or to receive any payments arising out of, or
based upon, such right of subrogation until the principal of (and premium, if
any) and interest on this Security and all other Securities issued under the
Indenture shall have been paid in full.

                  This Senior Subordinated Guarantee shall remain in full force
and effect and continue to be effective should any petition be filed by or
against the Company for liquidation or reorganization, should the Company become
insolvent or make an assignment for the benefit of creditors or should a
receiver or trustee be appointed for all or any significant part of the
Company's assets, and shall, to the fullest extent permitted by law, continue to
be effective or be reinstated, as the case may be, if at any time payment and
performance of the Securities is, pursuant to applicable law, rescinded or
reduced in amount, or must otherwise be restored or returned by any obligee on
the Securities, whether as a "voidable preference," "fraudulent transfer" or
otherwise, all as though such payment or performance had not been made. In the
event that any payment, or any part thereof, is rescinded, reduced, restored or
returned, the Securities shall, to the fullest extent permitted by law, be
reinstated and deemed reduced only by such amount paid and not so rescinded,
reduced, restored or returned.

                  The Guarantors shall have the right to seek contribution from
any non-paying Guarantor so long as the exercise of such right does not impair
the rights of the Holders under this Senior Subordinated Guarantee.

                  The Guarantors or any particular Guarantor shall be released
from this Senior Subordinated Guarantee upon the terms and subject to certain
conditions provided in the Indenture.

accordance with the terms of the Indenture, each Person that becomes a
Subsidiary Guarantor after the date of the Indenture will be deemed to have
executed and delivered this Subsidiary Guarantee for the benefit of the Holder
of the Security upon which this Subsidiary Guarantee is endorsed, with the same
effect as if such Subsidiary Guarantor was named below and had executed and
delivered this Subsidiary Guarantee.

                  All terms used in this Senior Subordinated Guarantee which are
defined in the Indenture referred to in the Security upon which this Senior
Subordinated Guarantee is endorsed shall have the meanings assigned to them in
such Indenture.

                  This Senior Subordinated Guarantee shall not be valid or
obligatory for any purpose until the certificate of authentication on the
Security upon which this Senior Subordinated Guarantee is endorsed shall have
been executed by the Trustee under the Indenture by manual signature.

                  Reference is made to Article Thirteen of the Indenture for
further provisions with respect to this Senior Subordinated Guarantee.

                  THIS SENIOR SUBORDINATED GUARANTEE SHALL BE GOVERNED BY AND
CONSTRUED IN ACCORDANCE WITH THE LAW OF THE STATE OF NEW YORK.

         which may be required by or advisable under United States laws or
         regulations or advisable (as determined by the Company) in connection
         with the marketing of Securities of the series.
    

                  (c) All Securities of any one series and interest coupons, if

                                       29
<PAGE>   38
All Securities of any one series need not be issued at the same time and, unless
otherwise provided, a series may be reopened, without the consent of the
Holders, for issuances of additional Securities of such series.

                  (d) If any of the terms of the Securities of any series are
established by action taken pursuant to a Board Resolution, a copy of such Board
Resolution shall be delivered to the Trustee at or prior to the delivery of the
Officers' Certificate setting forth, or providing the manner for determining,
the terms of the Securities of such series, and an appropriate record of any
action taken pursuant thereto in connection with the issuance of any Securities
of such series shall be delivered to the Trustee prior to the authentication and
delivery thereof.

   
                  Section 3.2. Denominations. Unless otherwise provided as
contemplated by Section 3.1, any Registered Securities of a series denominated
in Dollars shall be issuable in denominations of U.S. $1,000 and any integral
multiple thereof and any Bearer Securities of a series denominated in Dollars
shall be issuable in the denomination of U.S. $5,000 and any integral multiple
thereof. Securities denominated in a Foreign Currency shall be issuable in such
denominations as are established with respect to such Securities in or pursuant
to this Indenture.
    

                  Section 3.3. Execution, Authentication, Delivery and Dating.
Securities shall be executed on behalf of the Company by the Chairman of the
Board, the President, the Chief Executive Officer, the Chief Operating Officer,
the Chief Financial Officer or any Vice President of the Company, and need not
be attested. The Company's seal shall be reproduced on the Securities. The
signatures of any of these officers on the Securities may be manual or
facsimile. The interest coupons, if any, of Bearer Securities shall bear the
facsimile signature of the Chairman of the Board, the President, the Chief
Executive Officer, the Chief Operating Officer, the Chief Financial Officer or
any Vice President of the Company, and need not be attested.

                  Securities and interest coupons bearing the manual or
facsimile signatures of individuals who were at any time Officers of the Company
shall bind the Company, notwithstanding that such individuals or any of them
have ceased to be Officers prior to the authentication and delivery of such
Securities or were not Officers at the date of such Securities.

                  At any time and from time to time, the Company may deliver
Securities, together with any interest coupons appertaining thereto, of any
series executed by the Company and having endorsed (by attachment or imprint)
thereon the Senior Subordinated Guarantees executed as provided in Section 16.2
by the Guarantors to the Trustee for authentication, together with a Company
Order for the authentication and delivery of such Securities with such Senior
Subordinated Guarantees endorsed thereon,



                                       30
<PAGE>   39
and the Trustee in accordance with such Company Order shall authenticate and
deliver such Securities with such Senior Subordinated Guarantees endorsed
thereon to or upon the order of the Company (as set forth in such Company
Order); provided, however, that, in the case of Securities of a series offered
in a Periodic Offering, the Trustee shall authenticate and deliver such
Securities from time to time in accordance with such other procedures
(including, without limitation, the receipt by the Trustee of oral or electronic
instructions from the Company or its duly authorized agents, promptly confirmed
in writing) acceptable to the Trustee as may be specified by or pursuant to a
Company Order delivered to the Trustee prior to the time of the first
authentication of Securities of such series.

                  If the form or terms of the Securities with the Senior
Guarantees endorsed thereon of a series have been established by or pursuant to
one or more Board Resolutions or one or more indentures supplemental hereto as
permitted by Sections 2.1 and 3.1, in authenticating such Securities with the
Senior Guarantees endorsed thereon and accepting the additional responsibilities
under this Indenture in relation to such Securities with the Senior Guarantees
endorsed thereon, the Trustee shall be entitled to receive, and (subject to
section 315(a) through (d) of the Trust Indenture Act) shall be fully protected
in relying upon,

                  (i) an Opinion of Counsel stating:

                  (1) if the form or forms of such Securities and any interest
         coupons with Senior Guarantees endorsed thereon have been established
         by or pursuant to a Board Resolution as permitted by Section 2.1, that
         such forms have been established in conformity with the provisions of
         this Indenture;

                  (2) if the terms of such Securities and any interest coupons
         with Senior Guarantees endorsed thereon have been, or, in the case of
         Securities of a series with Senior Guarantees endorsed thereon offered
         in a Periodic Offering, will be, established by or pursuant to a Board
         Resolution as permitted by Section 3.1, that such terms have been, or,
         in the case of Securities of a series with Senior Guarantees endorsed
         thereon offered in a Periodic Offering, will be, established in
         conformity with the provisions of this Indenture, subject, in the case
         of Securities with Senior Guarantees endorsed thereon offered in a
         Periodic Offering, to any conditions specified in such Opinion of
         Counsel;

                  (3) if the form or terms of such Securities have been
         established in an indenture supplemental hereto, that such supplemental
         indenture has been duly authorized, executed and delivered by the
         Company and the Guarantors and, when duly authorized, executed and
         delivered by the Trustee, will constitute a legal, valid and binding
         obligation enforceable against the Company and the Guarantors



                                       31
<PAGE>   40
         in accordance with its terms, subject to (i) bankruptcy, insolvency,
         fraudulent transfer, reorganization, moratorium and other similar laws
         of general applicability relating to or affecting the enforcement of
         creditors' rights and to general principles of equity (regardless of
         whether enforcement is sought in a proceeding in equity or at law), and
         (ii) such other reasonable exceptions as may be specified in such
         Opinion of Counsel; and

                  (4) that such Securities, together with any interest coupons
         appertaining thereto, when issued by the Company and the Guarantors and
         authenticated and delivered by the Trustee in the manner and subject to
         any conditions specified in such Opinion of Counsel, will constitute
         valid and legally binding obligations of the Company and the
         Guarantors, enforceable against the Company and the Guarantors in
         accordance with their terms, subject to (i) bankruptcy, insolvency,
         fraudulent transfer, reorganization, moratorium and other similar laws
         of general applicability relating to or affecting the enforcement of
         creditors' rights and to general equity principles (regardless of
         whether enforcement is sought in a proceeding in equity or at law) and
         except further as enforcement thereof may be limited by (A)
         requirements that a claim with respect to any Securities or Senior
         Guarantees denominated other than in Dollars (or a Foreign Currency or
         currency unit judgment in respect of such claim) be converted into
         Dollars at a rate of exchange prevailing on a date determined pursuant
         to applicable law or (B) governmental authority to limit, delay or
         prohibit the making of payments in Foreign Currencies or currency units
         or payments outside the United States, and (ii) such other reasonable
         exceptions as may be specified in such Opinion of Counsel; and

                  (ii) an Officers' Certificate stating that all conditions
precedent provided for in this Indenture relating to the issuance of such
Securities have been complied with and that, to the knowledge of the signers of
such certificate, no Event of Default with respect to such Securities shall have
occurred and be continuing.

                  Notwithstanding that such form or terms have been so
established, the Trustee shall have the right to decline to authenticate such
Securities if, in the opinion of the Trustee (after consultation with counsel),
the issue of such Securities pursuant to this Indenture will materially
adversely affect the Trustee's own rights, duties or immunities under this
Indenture or otherwise or if the Trustee determines that such authentication may
not lawfully be made.

                  Notwithstanding the provisions of Section 3.1 and of the two
preceding paragraphs, if all of the Securities of any series are not to be
issued at one time, it shall not be necessary to deliver the Officers'
Certificate otherwise required pursuant to Section 3.1 or the Company Order and
Opinion of Counsel otherwise required pursuant to the two


                                       32
<PAGE>   41
preceding paragraphs in connection with the authentication of each Security of
such series if such documents, with appropriate modifications to cover such
future issuances, are delivered at or prior to the authentication upon original
issuance of the first Security of such series to be issued.

                  With respect to Securities with Senior Guarantees endorsed
thereon of a series offered in a Periodic Offering, the Trustee may rely, as to
the authorization by the Company of any of such Securities and by the Guarantors
of any such Senior Guarantees endorsed thereon, the form and terms thereof and
the legality, validity, binding effect and enforceability thereof, upon the
Opinion of Counsel and the other documents delivered pursuant to Sections 2.1
and 3.1 and this Section, as applicable, in connection with the first
authentication of Securities of such series.

                  If the Company shall establish pursuant to Section 3.1 that
the Securities of a series are to be issued in whole or in part in global form,
then the Company and the Guarantors shall execute and the Trustee shall, in
accordance with this Section and the Company Order with respect to such series,
authenticate and deliver one or more Securities with Senior Guarantees endorsed
thereon in global form that (i) shall represent and shall be denominated in an
amount equal to the aggregate principal amount of the Outstanding Securities of
such series to be represented by such Security or Securities in global form,
(ii) shall be registered, if a Registered Security, in the name of the
Depositary for such Security or Securities in global form or the nominee of such
Depositary, (iii) shall be delivered by the Trustee to such Depositary or
pursuant to such Depositary's instruction and (iv) shall bear the legend set
forth in Section 2.5.

                  Each Depositary designated pursuant to Section 3.1 for a
Registered Security in global form must, at the time of its designation and at
all times while it serves as Depositary, be a clearing agency registered under
the Securities Exchange Act of 1934 and any other applicable statute or
regulation. If requested by the Company, the Trustee shall enter into an
agreement with a Depositary governing the respective duties and rights of such
Depositary and the Trustee with regard to Securities with Senior Guarantees
endorsed thereon issued in global form.

                  Each Registered Security shall be dated the date of its
authentication and each Bearer Security shall be dated as of the date specified
pursuant to Section 3.1.

                  No Security or interest coupon appertaining thereto or Senior
Guarantees endorsed thereon shall be entitled to any benefits under this
Indenture or be valid or obligatory for any purpose until authenticated by the
manual signature of one of the authorized signatories of the Trustee or an
Authenticating Agent and no interest coupon shall be valid until the Security to
which it appertains has been so authenticated. Such signature upon any Security
with Senior Guarantees endorsed thereon shall be conclusive



                                       33
<PAGE>   42
evidence, and the only evidence, that such Security and Senior Guarantee has
been duly authenticated and delivered under this Indenture and is entitled to
the benefits of this Indenture. Except as permitted by Section 3.6 or 3.7, the
Trustee shall not authenticate and deliver any Bearer Security unless all
appurtenant interest coupons for interest then matured have been detached and
cancelled.

                  Notwithstanding the foregoing, if any Security shall have been
authenticated and delivered hereunder but never issued and sold by the Company,
and the Company shall deliver such Security to the Trustee for cancellation as
provided in Section 3.9 together with a written statement (which need not comply
with Section 1.2 hereof and need not be accompanied by an Officers' Certificate
or an Opinion of Counsel) stating that such Security has never been issued and
sold by the Company, for all purposes of this Indenture such Security shall be
deemed never to have been authenticated and delivered hereunder and shall not be
entitled to the benefits of this Indenture.

                  Section 3.4. Temporary Securities. Pending the preparation of
definitive Securities of any series, the Company and the Guarantors may execute
and, upon Company Order, the Trustee shall authenticate and deliver temporary
Securities with Senior Guarantees endorsed thereon of such series which are
printed, lithographed, typewritten, mimeographed or otherwise produced, in any
authorized denomination, substantially of the tenor and form, with or without
interest coupons, of the definitive Securities with Senior Guarantees endorsed
thereon in lieu of which they are issued and with such appropriate insertions,
omissions, substitutions and other variations as the officers executing such
Securities and such Senior Guarantees may determine, as conclusively evidenced
by their execution of such Securities and interest coupons, if any, and such
Senior Guarantees. In the case of Securities of any series, such temporary
Securities may be in global form, representing all or a portion of the
Outstanding Securities of such series.

                  Except in the case of temporary Securities in global form,
each of which shall be exchanged in accordance with the provisions thereof, if
temporary Securities of any series are issued, the Company and the Guarantors
will cause definitive Securities with Senior Guarantees endorsed thereon of such
series to be prepared without unreasonable delay. After preparation of
definitive Securities of such series, the temporary Securities of such series
shall be exchangeable for definitive Securities of such series upon surrender of
the temporary Securities of such series at the office or agency of the Company
pursuant to Section 9.2 in a Place of Payment for such series, without charge to
the Holder. Upon surrender for cancellation of any one or more temporary
Securities of any series (accompanied by any unmatured interest coupons
appertaining thereto), the Company and the Guarantors shall execute and the
Trustee shall authenticate and deliver in exchange therefor a like principal
amount of definitive Securities with


                                       34
<PAGE>   43
Senior Guarantees endorsed thereon of the same series of authorized
denominations and of like tenor; provided, however, that no definitive Bearer
Security shall be delivered in exchange for a temporary Registered Security; and
provided, further, that no definitive Bearer Security shall be delivered in
exchange for a temporary Bearer Security unless such delivery shall occur only
outside the United States. Until so exchanged, the temporary Securities of any
series shall in all respects be entitled to the same benefits under this
Indenture as definitive Securities of such series except as otherwise specified
as contemplated by Section 3.1.

                  Section 3.5. Registration, Transfer and Exchange. The Company
shall cause to be kept at the Corporate Trust Office of the Trustee or in any
office or agency to be maintained by the Company in accordance with Section 9.2
in a Place of Payment a register (the "Register") in which, subject to such
reasonable regulations as it may prescribe, the Company shall provide for the
registration of Registered Securities and the registration of transfers of
Registered Securities. The Register shall be in written form or any other form
capable of being converted into written form within a reasonable time. The
Trustee is hereby initially appointed "Registrar" for the purpose of registering
Registered Securities and transfers of Registered Securities as herein provided.

                  Upon surrender for registration of transfer of any Registered
Security of any series at the office or agency maintained pursuant to Section
9.2 in a Place of Payment for that series, the Company and the Guarantors shall
execute, and the Trustee shall authenticate and deliver, in the name of the
designated transferee or transferees, one or more new Registered Securities with
Senior Guarantees endorsed thereon of the same series, of any authorized
denominations and of a like aggregate principal amount and tenor and containing
identical terms and provisions.

                  Bearer Securities (except for any temporary global Bearer
Securities) or any interest coupons appertaining thereto (except for interest
coupons attached to any temporary global Bearer Security) shall be transferable
by delivery.

                  At the option of the Holder, Registered Securities of any
series (except a Registered Security in global form) may be exchanged for other
Registered Securities of the same series, of any authorized denominations, of a
like aggregate principal amount and tenor and containing identical terms and
provisions, upon surrender of the Registered Securities to be exchanged at such
office or agency. Whenever any Registered Securities are so surrendered for
exchange, the Company and the Guarantors shall execute, and the Trustee shall
authenticate and deliver, the Registered Securities with Senior Guarantees
endorsed thereon which the Holder making the exchange is entitled to receive.
Unless otherwise specified as contemplated by Section 3.1, Bearer Securities may
not be issued in exchange for Registered Securities.




                                       35
<PAGE>   44
                  Unless otherwise specified as contemplated by Section 3.1, at
the option of the Holder, Bearer Securities of such series may be exchanged for
Registered Securities (if the Securities of such series are issuable in
registered form) or Bearer Securities (if Bearer Securities of such series are
issuable in more than one denomination and such exchanges are permitted by such
series) of the same series, of any authorized denominations, of like aggregate
principal amount and tenor and containing identical terms and conditions, upon
surrender of the Bearer Securities to be exchanged at any such office or agency,
with all unmatured interest coupons and all matured interest coupons in default
thereto appertaining. If the Holder of a Bearer Security is unable to produce
any such unmatured interest coupon or coupons or matured interest coupon or
coupons in default, such exchange may be effected if the Bearer Securities are
accompanied by payment in funds acceptable to the Company and the Trustee in an
amount equal to the face amount of such missing interest coupon or coupons, or
the surrender of such missing interest coupon or interest coupons may be waived
by the Company, the Guarantors and the Trustee if there be furnished to them
such security or indemnity as they may require to save each of them and any
Paying Agent harmless. If thereafter the Holder of such Security shall surrender
to any Paying Agent any such missing interest coupon in respect of which such a
payment shall have been made, such Holder shall be entitled to receive the
amount of such payment; provided, however, that, except as otherwise provided in
Section 9.2, interest represented by interest coupons shall be payable only upon
presentation and surrender of those interest coupons at an office or agency
located outside the United States. Notwithstanding the foregoing, in case any
Bearer Security of any series is surrendered at any such office or agency in
exchange for a Registered Security of the same series after the close of
business at such office or agency on (i) any Regular Record Date and before the
opening of business at such office or agency on the relevant Interest Payment
Date, or (ii) any Special Record Date and before the opening of business at such
office or agency on the related date for payment of Defaulted Interest, such
Bearer Security shall be surrendered without the interest coupon relating to
such Interest Payment Date or proposed date of payment, as the case may be (or,
if such interest coupon is so surrendered with such Bearer Security, such
interest coupon shall be returned to the Person so surrendering the Bearer
Security), and interest or Defaulted Interest, as the case may be, will not be
payable on such Interest Payment Date or proposed date for payment, as the case
may be, in respect of the Registered Security issued in exchange for such Bearer
Security, but will be payable only to the Holder of such interest coupon, when
due in accordance with the provisions of this Indenture.

                  Notwithstanding anything herein to the contrary, the exchange
of Bearer Securities for Registered Securities shall be subject to applicable
laws and regulations in effect at the time of exchange. Neither the Company, the
Guarantors, the Trustee nor the Registrar shall exchange any Bearer Securities
for Registered Securities if it has received an Opinion of Counsel that as a
result of such exchange the Company would suffer



                                       36
<PAGE>   45
adverse consequences under the United States Federal income tax laws and
regulations then in effect and the Company has delivered to the Trustee a
Company Order directing the Trustee not to make such exchanges thereafter,
unless and until the Trustee receives a subsequent Company Order to the
contrary. The Company shall deliver copies of such Company Order to the
Registrar.

                  Notwithstanding any other provision of this Section, unless
and until it is exchanged in whole or in part for Securities in certificated
form, a Security in global form representing all or a portion of the Securities
of a series may not be transferred except as a whole by the Depositary for such
series to a nominee of such Depositary or by a nominee of such Depositary to
such Depositary or another nominee of such Depositary or by such Depositary or
any such nominee to a successor Depositary for such series or a nominee of such
successor Depositary.

                  If at any time the Depositary for the Securities of a series
notifies the Company that it is unwilling or unable to continue as Depositary
for the Securities of such series or if at any time the Depositary for the
Securities of such series shall no longer be eligible under Section 3.3, the
Company shall appoint a successor Depositary with respect to the Securities of
such series. If a successor Depositary for the Securities of such series is not
appointed by the Company prior to the resignation of the Depositary and, in any
event, within 90 days after the Company receives such notice or becomes aware of
such ineligibility, the Company's designation of the Depositary pursuant to
Section 3.1(b)(23) shall no longer be effective with respect to the Securities
of such series and the Company and the Guarantors shall execute, and the
Trustee, upon receipt of a Company Order for the authentication and delivery of
certificated Securities with Senior Guarantors endorsed thereon of such series
of like tenor, shall authenticate and deliver, Securities with Senior Guarantees
endorsed thereon of such series of like tenor in certificated form, in
authorized denominations and in an aggregate principal amount equal to the
principal amount of the Security or Securities of such series of like tenor in
global form in exchange for such Security or Securities in global form.

                  The Company may at any time in its sole discretion determine
that Securities issued in global form shall no longer be represented by such a
Security or Securities in global form. In such event the Company and the
Guarantors shall execute, and the Trustee, upon receipt of a Company Order for
the authentication and delivery of certificated Securities with Senior
Guarantees endorsed thereon of such series of like tenor, shall authenticate and
deliver, Securities with Senior Guarantees endorsed thereon of such series of
like tenor in certificated form, in authorized denominations and in an aggregate
principal amount equal to the principal amount of the Security or Securities of
such series of like tenor in global form in exchange for such Security or
Securities in global form.

<PAGE>   46
                  If specified by the Company pursuant to Section 3.1 with
respect to a series of Securities, the Depositary for such series may surrender
a Security in global form of such series in exchange in whole or in part for
Securities of such series in certificated form on such terms as are acceptable
to the Company, the Guarantors and such Depositary. Thereupon, the Company and
the Guarantors shall execute, and the Trustee shall authenticate and deliver,
without service charge,

                           (i) to each Person specified by such Depositary a new
                  certificated Security or Securities with Senior Guarantees
                  endorsed thereon of the same series of like tenor, of any
                  authorized denomination as requested by such Person in
                  aggregate principal amount equal to and in exchange for such
                  Person's beneficial interest in the Security in global form;
                  and

                           (ii) to such Depositary a new Security with Senior
                  Guarantees endorsed thereon in global form of like tenor in a
                  denomination equal to the difference, if any, between the
                  principal amount of the surrendered Security in global form
                  and the aggregate principal amount of certificated Securities
                  delivered to Holders thereof.

                  Upon the exchange of a Security with Senior Guarantees
endorsed thereon in global form for Securities with Senior Guarantees endorsed
thereon in certificated form, such Security with Senior Guarantees endorsed
thereon in global form shall be cancelled by the Trustee. Unless expressly
provided with respect to the Securities of any series that such Security may be
exchanged for Bearer Securities, Securities with Senior Guarantees endorsed
thereon in certificated form issued in exchange for a Security with Senior
Guarantees endorsed thereon in global form pursuant to this Section shall be
registered in such names and in such authorized denominations as the Depositary
for such Security with Senior Guarantees endorsed thereon in global form,
pursuant to instructions from its direct or indirect participants or otherwise,
shall instruct the Trustee in writing. The Trustee shall deliver such Securities
with Senior Guarantees endorsed thereon to the Persons in whose names such
Securities with Senior Guarantees endorsed thereon are so registered.

                  Whenever any Securities are surrendered for exchange, the
Company and the Guarantors shall execute, and the Trustee shall authenticate and
deliver, the Securities with Senior Guarantees endorsed thereon which the Holder
making the exchange is entitled to receive.

                  All Securities with Senior Guarantees endorsed thereon issued
upon any registration of transfer or upon any exchange of Securities with Senior
Guarantees endorsed thereon shall be the valid obligations of the Company and
the Guarantors,


                                       38
<PAGE>   47
evidencing the same debt, and entitled to the same benefits under this
Indenture, as the Securities surrendered upon such registration of transfer or
exchange.

                  Every Registered Security presented or surrendered for
registration of transfer or for exchange shall (if so required by the Company,
the Guarantors, the Registrar or the Trustee) be duly endorsed, or be
accompanied by a written instrument of transfer in form satisfactory to the
Company, the Guarantors, the Registrar and the Trustee 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 for any exchange of Securities, but the Company and the Guarantors
may require payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in connection with any registration or transfer or
exchange of Securities, other than exchanges pursuant to Section 3.4 or 11.7 not
involving any transfer.

                  The Company and the Guarantors shall not be required (i) to
issue, register the transfer of, or exchange any Securities with Senior
Guarantees endorsed thereon for a period beginning at the opening of business 15
days before any selection for redemption of Securities of like tenor and of the
series of which such Security is a part and ending at the close of business on
the earliest date on which the relevant notice of redemption is deemed to have
been given to all Holders of Securities of like tenor and of such series to be
redeemed; (ii) to register the transfer of or exchange any Registered Security
with Senior Guarantees endorsed thereon so selected for redemption, in whole or
in part, except the unredeemed portion of any Security being redeemed in part;
or (iii) to exchange any Bearer Security with Senior Guarantees endorsed thereon
so selected for redemption, except that such a Bearer Security may be exchanged
for a Registered Security of that series and like tenor; provided that such
Registered Security shall be simultaneously surrendered for redemption.

                  The foregoing provisions relating to registration, transfer
and exchange may be modified, supplemented or superseded with respect to any
series of Securities by a Board Resolution or in one or more indentures
supplemental hereto.

                  Section 3.6. Replacement Securities. If a mutilated Security
or a Security with a mutilated interest coupon appertaining to it is surrendered
to the Trustee, together with, in proper cases, such security or indemnity as
may be required by the Company, the Guarantors or the Trustee to save each of
them harmless, the Company and the Guarantors shall execute and the Trustee
shall authenticate and deliver a replacement Registered Security with Senior
Guarantees endorsed thereon, if such surrendered Security was a Registered
Security, or a replacement Bearer Security with Senior Guarantees endorsed
thereon with interest coupons corresponding to the interest coupons



                                       39
<PAGE>   48
appertaining to the surrendered Security, if such surrendered Security was a
Bearer Security, of the same series and date of maturity.

                  If there shall be delivered to the Company, the Guarantors and
the Trustee (i) evidence to their satisfaction of the destruction, loss or theft
of any Security or Security with a destroyed, lost or stolen interest coupon and
(ii) such security 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 Security or interest coupon has been acquired
by a bona fide purchaser, the Company and the Guarantors shall execute and the
Trustee shall authenticate and deliver in lieu of any such destroyed, lost or
stolen Security or in exchange for the Security to which a destroyed, lost or
stolen interest coupon appertains (with all appurtenant interest coupons not
destroyed, lost or stolen), a replacement Registered Security, if such Holder's
claim appertains to a Registered Security with Senior Guarantees endorsed
thereon, or a replacement Bearer Security with Senior Guarantees endorsed
thereon with interest coupons corresponding to the interest coupons appertaining
to the destroyed, lost or stolen Bearer Security or the Bearer Security to which
such lost, destroyed or stolen interest coupon appertains, if such Holder's
claim appertains to a Bearer Security, of the same series and principal amount,
containing identical terms and provisions and bearing a number not
contemporaneously outstanding with interest coupons corresponding to the
interest coupons, if any, appertaining to the destroyed, lost or stolen
Security.

                  In case any such mutilated, destroyed, lost or stolen Security
or interest coupon has become or is about to become due and payable, the Company
and the Guarantors in their discretion may, instead of issuing a new Security or
interest coupon with Senior Guarantees endorsed thereon, pay such Security or
interest coupon; provided, however, that payment of principal of and any premium
or interest on Bearer Securities shall, except as otherwise provided in Section
9.2, be payable only at an office or agency located outside the United States
and, unless otherwise specified as contemplated by Section 3.1, any interest on
Bearer Securities shall be payable only upon presentation and surrender of the
interest coupons appertaining thereto.

                  Upon the issuance of any new Security under this Section, the
Company and the Guarantors 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, its agents
and counsel) connected therewith.

                  Every new Security with Senior Guarantees endorsed thereon of
any series with its interest coupons, if any, issued pursuant to this Section in
lieu of any destroyed, lost or stolen Security, or in exchange for a Security to
which a destroyed, lost or stolen interest coupon appertains, shall constitute
an original additional contractual obligation of


                                       40
<PAGE>   49
the Company and the relevant Guarantor, whether or not the destroyed, lost or
stolen Security and its interest coupon, if any, or the destroyed, lost or
stolen interest coupon, 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 Securities of that series and their interest coupons, if any,
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 Securities or
interest coupons.

                  Section 3.7. Payment of Interest; Interest Rights Preserved.
(a) Unless otherwise provided as contemplated by Section 3.1, interest, if any,
on any Registered Security which is payable, and is punctually paid or duly
provided for, on any Interest Payment Date shall be paid to the Person in whose
name that Security (or one or more Predecessor Securities) is registered at the
close of business on the Regular Record Date for such interest at the office or
agency maintained for such purpose pursuant to Section 9.2; provided, however,
that at the option of the Company, interest on any series of Registered
Securities that bear interest may be paid (i) by check mailed to the address of
the Person entitled thereto as it shall appear on the Register of Holders of
Securities of such series or (ii) at the expense of the Company, by wire
transfer to an account maintained by the Person entitled thereto as specified in
the Register of Holders of Securities of such series.

                  Unless otherwise provided as contemplated by Section 3.1, (i)
interest, if any, on Bearer Securities shall be paid only against presentation
and surrender of the interest coupons for such interest installments as are
evidenced thereby as they mature and (ii) original issue discount, if any, on
Bearer Securities shall be paid only against presentation and surrender of such
Securities; in either case at the office of a Paying Agent located outside the
United States, unless the Company shall have otherwise instructed the Trustee in
writing, provided that any such instruction for payment in the United States
does not cause any Bearer Security to be treated as a "registration-required
obligation" under United States laws and regulations. The interest, if any, on
any temporary Bearer Security shall be paid, as to any installment of interest
evidenced by an interest coupon attached thereto only upon presentation and
surrender of such interest coupon and, as to other installments of interest,
only upon presentation of such Security for notation thereon of the payment of
such interest. If at the time a payment of principal of or interest, if any, on
a Bearer Security or interest coupon shall become due, the payment of the full
amount so payable at the office or offices of all the Paying Agents outside the
United States is illegal or effectively precluded because of the imposition of
exchange controls or other similar restrictions on the payment of such amount in
Dollars, then the Company may instruct the Trustee in writing to make such
payments at a Paying Agent located in the United States, provided that provision
for such payment in the


                                       41
<PAGE>   50
United States would not cause such Bearer Security to be treated as a
"registration-required obligation" under United States laws and regulations.

                  (b) Unless otherwise provided as contemplated by Section 3.1,
any interest on Securities of any series which is payable, but is not punctually
paid or duly provided for, on any Interest Payment Date in the case of
Registered Securities and upon presentation and surrender of the applicable
interest coupon in accordance with the second paragraph of Section 3.7(a) in the
case of Bearer Securities (herein called "Defaulted Interest"), shall forthwith
cease to be payable to the Holders on the relevant Regular Record Date by virtue
of their having been such Holders, and such Defaulted Interest may be paid by
the Company, at its election in each case, as provided in clause (1) or (2)
below:

                  (1) In the case of Registered Securities, the Company may
         elect to make payment of such Defaulted Interest to the Persons in
         whose names such Registered Securities (or their respective Predecessor
         Securities) are registered at the close of business on a Special Record
         Date for the payment of such Defaulted Interest, which Shall be fixed
         in the following manner. The Company shall notify the Trustee in
         writing of the amount of Defaulted Interest proposed to be paid on each
         such Registered Security and the date of the proposed payment, and
         shall deposit with the Trustee an amount of money equal to the
         aggregate amount proposed to be paid in respect of such Defaulted
         Interest or shall make arrangements satisfactory to the trustee for
         such deposit prior to the date of the proposed payment, Such money when
         deposited to be held in trust for the benefit of the persons entitled
         to such Defaulted Interest as in this clause (1) 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 of such Registered Securities at his or her
         address as it appears in the 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 such Registered Securities (or their respective Predecessor
         Securities) are registered at the close of business on such Special
         Record Date and shall no longer be payable pursuant to the following
         clause (2).

                  (2)(x) In the case of Registered Securities, the Company may
         make payment of such Defaulted Interest to the Persons in whose names
         such Registered


                                       42
<PAGE>   51
         Securities (or their respective Predecessor Securities) are registered
         at the close of business on a specified date in any other lawful manner
         not inconsistent with the requirements of any securities exchange on
         which such Registered Securities may be listed, and upon such notice as
         may be required by such exchange, if, after notice given by the Company
         to the Trustee of the proposed payment pursuant to this clause (2)(x),
         such manner of payment shall be deemed practicable by the Trustee; or
         (y) unless otherwise provided as contemplated by Section 3.1, in the
         case of Bearer Securities, the Company may make payment of Defaulted
         Interest on such Bearer Securities in any lawful manner not
         inconsistent with the requirements of any securities exchange on which
         such Bearer Securities may be listed, and upon such notice as may be
         required by such exchange, if, after notice given by the Company to the
         Trustee of the proposed payment pursuant to this clause (2)(y), such
         manner of payment shall be deemed practicable by the Trustee.

                  (c) Subject to the foregoing provisions of this Section and
Section 3.5, each Security delivered under this Indenture upon registration of
transfer of or in exchange for or in lieu of any other Security shall carry the
rights to interest accrued and unpaid, and to accrue, which were carried by such
other Security.

                  (d) Subject to the provisions of Section 14.2, in the case of
any Registered Security which is converted or exchanged after any Regular Record
Date and on or prior to the next succeeding Interest Payment Date (other than
any Security the principal of (or premium, if any, on) which shall become due
and payable, whether at a Stated Maturity or by declaration of acceleration,
call for redemption, or otherwise, 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 or exchange and
such interest (whether or not punctually paid or duly provided for) shall be
paid to the Person in whose name that Registered Security (or any one or more
Predecessor Securities) is registered at the close of business on such Regular
Record Date. Except as otherwise expressly provided in the immediately preceding
sentence, in the case of any Security which is converted or exchanged, interest
whose Stated Maturity is after the date of conversion or exchange of such
Security shall not be payable.

                  Section 3.8. Persons Deemed Owners. Unless otherwise provided
as contemplated by Section 3.1, prior to due presentment of any Registered
Security for registration of transfer, the Company, the Guarantors, the Trustee
and any agent of the Company, any Guarantor or the Trustee may treat the Person
in whose name such Registered Security is registered as the owner of such
Registered Security for the purpose of receiving payment of principal of,
premium, if any, and (subject to Section 3.7) interest on such Registered
Security and for all other purposes whatsoever, whether or not such Registered
Security be overdue, and neither the Company, any Guarantor, the Trustee


                                       43
<PAGE>   52
nor any agent of the Company, the Guarantor or the Trustee shall be affected by
notice to the contrary.

                  Unless otherwise provided as contemplated by Section 3.1, the
Company, the Guarantors, the Trustee and any agent of the Company, any Guarantor
or the Trustee may treat the bearer of any Bearer Security and the bearer of any
interest coupon as the absolute owner of such Bearer Security or interest coupon
for the purpose of receiving payment thereof or on account thereof and for all
other purposes whatsoever, whether or not such Bearer Security or interest
coupon be overdue, and neither the Company, the Guarantors, the Trustee nor any
agent of the Company, any Guarantor or the Trustee shall be affected by notice
to the contrary.

                  None of the Company, the Guarantors, the Trustee or any agent
of the Company, any Guarantor or the Trustee shall have any responsibility or
liability for any aspect of the records relating to or payments made on account
of beneficial ownership interests of a Security in global form, or for
maintaining, supervising or reviewing any records relating to such beneficial
ownership interests. No holder of any beneficial interest in any Security in
global form, held on its behalf by or through a Depositary, shall have any
rights under this Indenture with respect to such Security in global form, and
such Depositary may be treated by the Company, the Guarantors, the Trustee and
any agent of the Company, any Guarantor or the Trustee as the owner of such
Security in global form for all purposes whatsoever. With respect to any
Security in global form, nothing herein shall prevent the Company, the
Guarantors or the Trustee, or any agent of the Company, any Guarantor or the
Trustee, from giving effect to any written certification, proxy or other
authorization furnished by any Depositary (or its nominee), as a Holder, with
respect to such Security in global form or impair, as between such Depositary
and owners of beneficial interests in such Security in global form, the
operation of customary practices governing the exercise of the rights of such
Depositary (or its nominee) as Holder of such Security in global form.

                  Section 3.9. Cancellation. All Securities and interest coupons
appertaining thereto, if any, surrendered for payment, redemption, conversion,
registration of transfer or exchange or for credit against any sinking fund
payment shall, if surrendered to any Person other than the Trustee, be delivered
to the Trustee and, together with the Senior Guarantee endorsed thereon, shall
be promptly cancelled by it. The Company may at any time deliver to the Trustee
for cancellation any Securities, together with interest coupons appertaining
thereto, if any, previously authenticated and delivered hereunder which the
Company may have acquired in any manner whatsoever, and may deliver to the
Trustee (or to any other Person for delivery to the Trustee) for cancellation
any Securities, together with interest coupons appertaining thereto, if any,
previously authenticated hereunder which the Company has not issued and sold,
and all Securities and interest coupons so delivered shall, together with the
Senior Guarantee endorsed thereon, be


                                       44
<PAGE>   53
promptly cancelled by the Trustee. No Securities shall be authenticated in lieu
of or in exchange for any Securities cancelled as provided in this Section 3.9,
except as expressly permitted by this Indenture. All cancelled Securities and
interest coupons held by the Trustee shall, together with the Senior Guarantee
endorsed thereon, be disposed of in accordance with its customary procedures,
and the Trustee shall thereafter deliver to the Company a certificate with
respect to such disposition.

                  Section 3.10. Computation of Interest. Except as otherwise
specified as contemplated by Section 3.1, interest on the Securities of each
series shall be computed on the basis of a 360-day year of twelve 30-day months.

                  Section 3.11. CUSIP Numbers. The Company in issuing the
Securities may use "CUSIP" numbers (if then generally in use and in addition to
the other identification numbers printed on the Securities), and, in such case,
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 Securities
or as contained in any notice of a redemption and that reliance may be placed
only on the other identification numbers printed on the Securities, and any such
redemption shall not be affected by any defect in or omission of such numbers.

                  Section 3.12. Currency and Manner of Payment in Respect of
Securities. Unless otherwise specified with respect to any Securities pursuant
to Section 3.1, payment of the principal of, premium, if any, and interest, if
any, on any Security of such series will be made in the currency or currencies
or currency unit or units in which such Security is payable. The provisions of
this Section 3.12 may be modified or superseded pursuant to Section 3.1 with
respect to any Securities.

                     Satisfaction, Discharge and Defeasance

                  Section 4.1. Termination of Company's Obligations Under the
Indenture. This Indenture shall upon a Company Request cease to be of further
effect with respect to Securities of or within any series and any interest
coupons appertaining thereto (except as to (i) rights of registration, transfer
or exchange of such Securities, (ii) rights of replacement of such Securities
which may have been lost, stolen or mutilated as herein expressly provided for,
(iii) rights of holders of Securities to receive payments of principal thereof
and interest thereon, upon the Stated Maturity thereof (but not upon
acceleration), and rights of the Holders to receive mandatory sinking fund
payments, if any, (iv) rights of holders of Securities to convert or exchange
Securities, (v) rights, obligations, duties and immunities of the Trustee
hereunder, (vi) any rights of the Holders of Securities of such series as
beneficiaries hereof with respect to the property so

         Section 9.3) have been delivered to the Trustee for cancellation; or

                  (B) all Securities of such series and, in the case of (i) or
         (ii) below, any interest coupons appertaining thereto not theretofore
         delivered to the Trustee for cancellation:

                                    (i) have become due and payable, or

                           Company,

                  and the Company, in the case of (i), (ii) or (iii) above, has

                  Trustee as trust funds in trust for the purpose an amount in
                  the currency or currencies or currency unit or units in which
                  the Securities of such series are payable, sufficient to pay
                  and discharge the entire indebtedness on such Securities and
                  such interest coupons not theretofore delivered to the Trustee
                  for cancellation, for principal, premium, if any, and
                  interest, with respect thereto, to the date of



                                       46
<PAGE>   55
                  such deposit (in the case of Securities which have become due
                  and payable) or to the Stated Maturity or Redemption Date, as
                  the case may be;

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

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

Notwithstanding the satisfaction and discharge of this Indenture, the obligation
of the Company to the Trustee and any predecessor Trustee under Section 6.7, the
obligations of the Company to any Authenticating Agent under Section 6.13 and,
if money shall have been deposited with the Trustee pursuant to subclause (B) of
clause (1) of this Section, the obligations of the Trustee under Section 4.2,
Section 9.2, the last paragraph of Section 9.3 and Section 10.1 shall survive.

                  Section 4.2. Application of Trust Funds. Subject to the
provisions of the last paragraph of Section 9.3, all money deposited with the
Trustee pursuant to Section 4.1 shall be held in trust and applied by it, in
accordance with the provisions of the Securities, the interest coupons
appertaining thereto, if any, and this Indenture, to the payment, either
directly or through any Paying Agent (including the Company acting as its own
Paying Agent) as the Trustee may determine, to the Persons entitled thereto, of
the principal, premium, if any and any interest for whose payment such money has
been deposited with or received by the Trustee, but such money need not be
segregated from other funds except as otherwise provided herein and except to
the extent required by law.

                  Section 4.3. Applicability of Defeasance Provisions; Company's
Option to Effect Defeasance or Covenant Defeasance. Except as otherwise
specified as contemplated by Section 3.1 for the Securities of any series, the
provisions of Sections 4.3 through 4.9 inclusive, with such modifications
thereto as may be specified pursuant to Section 3.1 with respect to any series
of Securities, shall be applicable to the Securities and any interest coupons
appertaining thereto.

                  Section 4.4. Defeasance and Discharge. On and after the date
on which the conditions set forth in Section 4.6 are satisfied with respect to
the Securities of or within any series, the Company shall be deemed to have paid
and been discharged from its obligations with respect to such Securities and any
interest coupons appertaining thereto (hereinafter "defeasance"). For this
purpose, such defeasance means that (i) the Company shall be deemed to have paid
and discharged the entire indebtedness represented by such Securities and any
interest coupons appertaining thereto which shall thereafter be deemed to be
"Outstanding" only for the purposes of Section 4.7 and the


                                       47
<PAGE>   56
other Sections of this Indenture referred to in clause (ii) of this Section, and
to have satisfied all its other obligations under such Securities and any
interest coupons appertaining thereto and this Indenture insofar as such
Securities and any interest coupons appertaining thereto are concerned (and the
Trustee, upon payment of all amounts due it under Section 6.7, at the expense of
the Company, shall on a Company Order execute proper instruments acknowledging
the same) and (ii) the Guarantors shall be released from all of their
obligations under their Senior Guarantees and under Article 16 of this
Indenture, except the following which shall survive until otherwise terminated
or discharged hereunder: (i) the rights of Holders of such Securities and any
interest coupons appertaining thereto to receive, solely from the trust funds
described in Section 4.6(a) and as more fully set forth in such Section,
payments in respect of the principal of, premium, if any, and interest, if any,
on such Securities or any interest coupons appertaining thereto when such
payments are due; (ii) the Company's obligations with respect to such Securities
under Sections 3.5, 3.6, 9.2 and 9.3 and with respect to the payment of
additional amounts, if any, payable with respect to such Securities as specified
pursuant to Section 3.1(b)(16); (iii) the Company's obligations with respect to
a conversion or exchange of such Securities; (iv) the rights, powers, trusts,
duties and immunities of the Trustee hereunder and (v) this Article 4. Subject
to compliance with this Article 4, the Company may defease the Securities of any
series and any interest coupons appertaining thereto under this Section 4.4
notwithstanding a prior covenant defeasance (as defined herein) under Section
4.5 with respect to such Securities and any interest coupons appertaining
thereto. Following a defeasance, payment of such Securities may not be
accelerated because of an Event of Default.

                  Section 4.5. Covenant Defeasance. On and after the date on
which the conditions set forth in Section 4.6 (other than Section 4.6(c)) are
satisfied with respect to the Securities of or within any series, (i) the
Company shall be released from its obligations under Sections 7.1 and 9.4 and,
if specified pursuant to Section 3.1, its obligations under any other covenant,
with respect to such Securities and any interest coupons appertaining thereto
and (ii) the occurrence of any event specified in Sections 5.1(3) or 5.1(7)
(with respect to any of the obligations described in clause (i) above) or 5.1(4)
shall be deemed not to be or result in a Default or Event of Default
(hereinafter, "covenant defeasance"), and such Securities and any interest
coupons appertaining thereto shall thereafter be deemed to be not "Outstanding"
for the purposes of any request, demand, authorization, direction, notice,
waiver, consent or declaration or Act of Holders (and the consequences of any
thereof) in connection with Section 7.1 or 9.4, such other covenant specified
pursuant to Section 3.1, or Section 5.1(4), but shall continue to be deemed
"Outstanding" for all other purposes hereunder. For this purpose, such covenant
defeasance means that, with respect to such Securities and any interest coupons
appertaining thereto, the Company may omit to comply with and shall have no
liability in respect of any term, condition or limitation set forth in any such
Section or



                                       48
<PAGE>   57
such other covenant, whether directly or indirectly, by reason of any reference
elsewhere herein to any such Section or such other covenant or by reason of
reference in any such Section or such other covenant to any other provision
herein or in any other document and such omission to comply shall not constitute
a Default or an Event of Default under Section 5.1(3), 5.1(4) or 5.1(7) or
otherwise, as the case may be, but, except as specified above, the remainder of
this Indenture and such Securities and any interest coupons appertaining thereto
shall be unaffected thereby.

                  Section 4.6. Conditions to Defeasance or Covenant Defeasance.
The following shall be the conditions to application of Section 4.4 or Section
4.5 to any Securities of or within a series and any interest coupons
appertaining thereto:

                  (a) The Company shall have deposited or caused to be deposited
irrevocably with the Trustee (or another trustee satisfying the requirements of
Section 6.9 who shall agree to comply with, and shall be entitled to the
benefits of, the provisions of Sections 4.3 through 4.9 inclusive and the last
paragraph of Section 9.3 applicable to the Trustee, for purposes of such
Sections also a "Trustee") as trust funds in trust for the purpose of making the
payments referred to in clauses (x) and (y) of this Section 4.6(a), specifically
pledged as security for, and dedicated solely to, the benefit of the Holders of
such Securities and any interest coupons appertaining thereto, with written
instructions to the Trustee as to the application thereof, (A) money in an
amount (in such currency, currencies or currency unit or units in which such
Securities and any interest coupons appertaining thereto are then specified as
payable at Maturity), or (B) if Securities of such series are not subject to
repayment at the option of Holders, Government Obligations which through the
payment of interest and principal in respect thereof in accordance with their
terms will provide, not later than one day before the due date of any payment
referred to in clause (x) or (y) of this Section 4.6(a), money in an amount or
(C) a combination thereof in an amount, sufficient, in the opinion of a
nationally recognized firm of independent certified public accountants or a
nationally recognized investment banking firm expressed in a written
certification thereof delivered to the Trustee, to pay and discharge, and which
shall be applied by the Trustee to pay and discharge, (x) the principal of,
premium, if any, and interest, if any, on such Securities and any interest
coupons appertaining thereto on the Maturity of such principal or installment of
principal or interest and (y) any mandatory sinking fund payments applicable to
such Securities on the day on which such payments are due and payable in
accordance with the terms of this Indenture and such Securities and any interest
coupons appertaining thereto. Before such a deposit the Company may make
arrangements satisfactory to the Trustee for the redemption of Securities at a
future date or dates in accordance with Article 11 which shall be given effect
in applying the foregoing.

                  (b) No Default or Event of Default with respect to the
Securities of that series shall have occurred or be continuing on the date of
such a deposit or shall occur as


                                       49
<PAGE>   58
a result of such a deposit or, insofar as Sections 5.1(5) and (6) are concerned,
shall occur at any time during the period ending on the 91st day after the date
of such deposit (it being understood that this condition shall not be deemed
satisfied until the expiration of such period).

                  (c) In the case of an election under Section 4.4, the Company
shall have delivered to the Trustee an Officers' Certificate and an Opinion of
Counsel to the effect that (i) the Company has received from, or there has been
published by, the Internal Revenue Service a ruling, or (ii) since the date of
execution of this Indenture, there has been a change in the applicable U.S.
Federal income tax law, in either case to the effect that, and based thereon
such opinion shall confirm that, the Holders of such Securities and any interest
coupons appertaining thereto will not recognize income, gain or loss for U.S.
Federal income tax purposes as a result of such defeasance and will be subject
to U.S. Federal income tax on the same amount and in the same manner and at the
same times, as would have been the case if such deposit, defeasance and
discharge had not occurred.

                  (d) In the case of an election under Section 4.5, the Company
shall have delivered to the Trustee an Officers' Certificate and an Opinion of
Counsel to the effect that the Holders of such Securities and any interest
coupons appertaining thereto will not recognize income, gain or loss for U.S.
Federal income tax purposes as a result of such covenant defeasance and will be
subject to U.S. Federal income tax on the same amount and in the same manner and
at the same times, as would have been the case if such deposit and covenant
defeasance had not occurred.

                  (e) The Company shall have delivered to the Trustee an
Officers' Certificate and an Opinion of Counsel, each stating that all
conditions precedent to the defeasance under Section 4.4 or the covenant
defeasance under Section 4.5 (as the case may be) have been complied with.

                  (f) Such defeasance or covenant defeasance shall be effected
in compliance with any additional or substitute terms, conditions or limitations
which may be imposed on the Company in connection therewith as contemplated by
Section 3.1.

                  Section 4.7. Deposited Money and Government Obligations to Be
Held in Trust. Subject to the provisions of the last paragraph of Section 9.3,
all money and Government Obligations (or other property as may be provided
pursuant to Section 3.1) (including the proceeds thereof) deposited with the
Trustee pursuant to Section 4.6 in respect of any Securities of any series and
any interest coupons appertaining thereto shall be held in trust and applied by
the Trustee, in accordance with the provisions of such Securities and any
interest coupons appertaining thereto and this Indenture, to the payment, either
directly or through any Paying Agent (including the Company acting as its own
Paying Agent) as the Trustee may determine, to the Holders of such Securities



                                       50
<PAGE>   59
and any interest coupons appertaining thereto of all sums due and to become due
thereon in respect of principal, premium, if any, and interest, if any, but such
money need not be segregated from other funds except as provided herein and
except to the extent required by law.

                  Section 4.8. Repayment to Company. The Trustee (and any Paying
Agent) shall promptly pay to the Company upon Company Request any excess money
or securities held by them at any time.

                  The provisions of the last paragraph of Section 9.3 shall
apply to any money or securities held by the Trustee or any Paying Agent under
this Article 4 that remain unclaimed for two years after the Maturity of any
series of Securities for which money or securities have been deposited pursuant
to Section 4.6(a).

                  Section 4.9. Indemnity for Government Obligations. The Company
shall pay, and shall indemnify the Trustee against, any tax, fee or other charge
imposed on or assessed against Government Obligations deposited pursuant to this
Article or the principal and interest and any other amount received on such
Government Obligations.

                  Section 4.10. Reinstatement. If the Trustee (or Paying Agent)
is unable to apply any money or Government Obligations in accordance with
Section 4.6 by reason of any order or judgment of any court or governmental
authority enjoining, restraining or otherwise prohibiting such application, then
the Company's obligations under this Indenture and the Securities shall be
revived and reinstated, with present and prospective effect, as though no
deposit had occurred pursuant to Section 4.6, until such time as the Trustee (or
Paying Agent) is permitted to apply all such money or Government Obligations in
accordance with Section 4.6; provided, however, that if the Company makes any
payment to the Trustee (or Paying Agent) of principal, premium, if any, or
interest on any Security following the reinstatement of its obligations, the
Trustee (or Paying Agent) shall promptly pay any such amount to the Holders of
the Securities and the Company shall be subrogated to the rights of the Holders
of such Securities to receive such payment from the money and Government
Obligations held by the Trustee (or Paying Agent).

                                    ARTICLE 5

                              Defaults and Remedies

                  Section 5.1. Events of Default. An "Event of Default" occurs
with respect to the Securities of any series if (whatever the reason for such
Event of Default and whether it shall be voluntary or involuntary or be effected
by operation of law or pursuant to any judgment, decree or order of any court or
any order, rule or regulation of any administrative or governmental body):

<PAGE>   60
                  (1) default in the payment of interest on any Security of that
         series or any interest coupon appertaining thereto or any additional
         amount payable with respect to any Security of that series as specified
         pursuant to Section 3.1(b)(16) when the same becomes due and payable
         and such default continues for a period of 30 days;

                  (2) default in the payment of any installment of the principal
         of or any premium on any Security of that series when the same becomes

                  (3) failure by the Company or any Guarantor to comply with any
         of its agreements or covenants in, or any of the provisions of, this
         Indenture with respect to any Security of that series (other than an
         agreement, covenant or provision for which non-compliance is elsewhere
         in this Section specifically dealt with), and such non-compliance
         continues for a period of 90 days after there has been given, by
         registered or certified mail, return receipt requested, to the Company
         by the Trustee or to the Company and the Trustee by the Holders of at
         least 25% in aggregate principal amount of the Outstanding Securities
         of the series, a written notice specifying such default or breach and
         requiring it to be remedied and stating that such notice is a "Notice
         of Default" hereunder;

                  (4) default by the Company or any Guarantor under any
         mortgage, indenture or instrument under which there may be issued, or

         Indenture) having an aggregate principal amount outstanding of at least
         $25,000,000, whether such Debt now exists or shall hereafter be
         created, and, as a result of such default, such Debt shall become due
         and payable, whether by acceleration or otherwise, and such
         acceleration shall not be rescinded, annulled or cured within a period
         of 30 days after there has been given, by registered or certified mail,
         return receipt requested, to the Company by the Trustee or to the
         Company and the Trustee by the Holders of at least 25% in aggregate
         principal amount of the Outstanding Securities of that series a written
         notice specifying such default and requiring it to be remedied and
         stating that such notice is a "Notice of Default" hereunder (it being
         understood however, that the Trustee shall not be deemed to have
         knowledge of such default under such agreement or instrument unless a
         Responsible Officer of the Trustee shall have received written notice
         thereof from the Company, from any Holder, from the holder of any such
         Debt or from the trustee under any such agreement or other instrument);
         provided, however, that if such default under such mortgage, indenture
         or instrument is remedied or cured by the Company or waived by the
         holders of such Debt, then the Event of Default hereunder by reason
         thereof shall be deemed likewise to have been thereupon remedied, cured
         or waived without further action upon the part of either the Trustee or
         any of such Holders;

         meaning of any Bankruptcy Law (A) commences a voluntary case, (B)
         consents to the entry of an order for relief against it in an
         involuntary case, (C) consents to the appointment of a Custodian of it
         or for all or substantially all of its property, (D) makes a general

         for 90 days; or

                  (7) there occurs any other Event of Default provided as
         contemplated by Section 3.1 with respect to Securities of that series.

                  The term "Bankruptcy Law" means Title 11, United States
Bankruptcy Code of 1978, as amended, or any similar United States federal or
state law relating to bankruptcy, insolvency, receivership, reorganization or

                  Section 5.2. Acceleration; Rescission and Annulment. If an
Event of Default with respect to the Securities of any series at the time
Outstanding (other than an Event of Default specified in clause (5) or (6) of
Section 5.1) occurs and is continuing, the Trustee or the Holders of at least
25% in aggregate principal amount of all of the Outstanding Securities of that
series, by written notice received by the Company (and, if given by the Holders,
received by the Trustee), may declare the principal (or, if the Securities of
that series are Original Issue Discount Securities or Indexed Securities, such
portion of the principal amount as may be specified in the terms of that series)
of and accrued interest, if any, on all the Securities of that series to be due
and payable and upon any such declaration such principal (or, in the case of
Original Issue Discount Securities or Indexed Securities, such specified amount)
and interest, if any, shall be immediately due and payable. If an Event of
Default specified in clause (5) or (6) of Section 5.1 with respect to the
Securities of any series at the time Outstanding occurs and is continuing, then
the principal (or, if the Securities of that series are Original Issue Discount
Securities or Indexed Securities, such portion of the principal amount as may be
specified in the terms of that series) of and accrued interest, if any, on all
the Securities of that series shall ipso facto be immediately due and payable

<PAGE>   62
                  At any time after such a declaration of acceleration with
respect to Securities of any series has been made and before a judgment or
decree for payment of the money due has been obtained by the Trustee as
hereinafter in this Article provided, the Holders of a majority in aggregate
principal amount of the Outstanding Securities of that series, by written notice
to the Trustee, may rescind and annul such declaration and its consequences if
all existing Defaults and Events of Default with respect to Securities of that
series, other than the non-payment of the principal of Securities of that series
which have become due solely by such declaration of acceleration, have been
cured or waived as provided in Section 5.7. No such rescission shall affect any
subsequent default or impair any right consequent thereon.

                  Section 5.3. Collection of Indebtedness and Suits for
Enforcement by Trustee. The Company covenants that if

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

                  (2) default is made in the payment of the principal of (or
         premium, if any, on) any Security at the Maturity thereof, the Company
         will, upon demand of the Trustee, pay to it, for the benefit of the
         Holders of such Securities or interest coupons, if any, the whole
         amount then due and payable on such Securities for principal, premium,
         if any, and interest and, to the extent that payment of such interest
         shall be legally enforceable, interest on any overdue principal,
         premium, if any, and on any overdue interest, at the rate or rates
         prescribed therefor in such Securities or interest coupons, if any,
         and, in addition thereto, such further amount as shall be sufficient to
         cover the costs and expenses of collection, including all amounts due
         the Trustee, its agents and counsel under Section 6.7.

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

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



                                       54
<PAGE>   63
Indenture or in aid of the exercise of any power granted herein, or to secure
any other proper remedy, subject, however, to Section 5.8.

                  Section 5.4. Trustee May File Proofs of Claim. In case of any
judicial proceeding relative to the Company (or any Guarantor or any other
obligor upon the Securities), its property or its creditors (or of any Guarantor
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 the Trustee
allowed in any such proceeding. In particular, the Trustee shall be 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 6.7.

                  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 of a Security or interest coupon any plan of reorganization, arrangement,
adjustment or composition affecting the Securities or the rights of any Holder
of a Security or interest coupon thereof or to authorize the Trustee to vote in
respect of the claim of any Holder of a Security or interest coupon in any such
proceeding; provided, however, that the Trustee may, on behalf of the Holders,
vote for the election of a trustee in bankruptcy or similar official and be a
member of a creditors' or other similar committee.

                  Section 5.5. Trustee May Enforce Claims Without Possession of
Securities. All rights of action and claims under this Indenture or the
Securities or the Senior Guarantees may be prosecuted and enforced by the
Trustee without the possession of any of the Securities or the production
thereof in any proceeding relating thereto.

                  Section 5.6 Delay or Omission Not Waiver. No delay or omission
by the Trustee or any Holder of any Securities to exercise any right or remedy
accruing upon an Event of Default shall impair any such right or remedy or
constitute a waiver of or acquiescence in any such Event of Default.

                  Section 5.7. Waiver of Past Defaults. The Holders of not less
than a majority in aggregate principal amount of Outstanding Securities of any
series by written notice to the Trustee may waive on behalf of the Holders of
all Securities of such series and any interest coupons appertaining thereto a
past Default or Event of Default with respect to that series and its
consequences except (i) a Default or Event of Default in the


                                       55
<PAGE>   64
payment of the principal of, premium, if any, or interest on any Security of
such series or any interest coupon appertaining thereto or (ii) in respect of a
covenant or provision hereof which pursuant to Article 8 cannot be amended or
modified without the consent of the Holder of each Outstanding Security of such
series affected. Upon any such waiver, such Default shall cease to exist, and
any Event of Default arising therefrom shall be deemed to have been cured, for
every purpose of this Indenture but no such waiver shall extend to any
subsequent or other default or impair any right consequent thereon.

                  Section 5.8. Control by Majority. The Holders of not less than
a majority in aggregate principal amount of the Outstanding Securities of each
series affected (with each such series voting as a class) shall have the right
to direct the time, method and place of conducting any proceeding for any remedy
available to the Trustee or exercising any trust or power conferred on it with
respect to Securities of that series; provided, however, that (i) the Trustee
may refuse to follow any direction that conflicts with any governmental rule or
law or this Indenture, (ii) the Trustee may refuse to follow any direction that
is unduly prejudicial to the rights of the Holders of Securities of such series
not consenting, or that would in the good faith judgment of the Trustee have a
substantial likelihood of involving the Trustee in personal liability without
adequate indemnity having been offered therefor and (iii) subject to Section
6.1, the Trustee may take any other action deemed proper by the Trustee which is
not inconsistent with such direction.

                  Section 5.9. Limitation on Suits by Holders. No Holder of any
Security of any series or any interest coupons appertaining thereto shall have
any right to institute any proceeding, judicial or otherwise, with respect to
this Indenture, or for the appointment of a receiver or trustee, or for any
other remedy hereunder, unless:

                  (1) the Holder has previously given written notice to the
         Trustee of a continuing Event of Default with respect to the Securities
         of that series;

                  (2) the Holders of at least 25% in aggregate principal amount
         of the Outstanding Securities of that series have made a written
         request to the Trustee to institute proceedings in respect of such
         Event of Default in its own name as Trustee hereunder;

                  (3) such Holder or Holders have offered to the Trustee
         indemnity satisfactory to the Trustee against any loss, liability or
         expense to be, or which may be, incurred by the Trustee in pursuing the
         remedy;

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




                                       56
<PAGE>   65
                  (5) during such 60-day period, the Holders of a majority in
         aggregate principal amount of the Outstanding Securities of that series
         have not given to the Trustee a direction inconsistent with such
         written request.

                  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 of such Holders, or to
obtain or to seek to obtain priority or preference over any other of such
Holders or to enforce any right under this Indenture, except in the manner
herein provided and for the equal and ratable benefit of all of such Holders.

                  Section 5.10. Rights of Holders to Receive Payment.
Notwithstanding any other provision of this Indenture, but subject to Section
9.2, the right of any Holder of a Security or interest coupon to receive payment
of principal of, premium, if any, and, subject to Sections 3.5 and 3.7, interest
on the Security, on or after the respective due dates expressed in the Security
(or, in case of redemption, on the Redemption Dates), the right of any Holder of
an interest coupon to receive payment of interest due as provided in such
interest coupon, or to bring suit for the enforcement of any such payment on or
after such respective dates, and the right, if any, to convert or exchange such
Security in accordance with Article 14, shall not be impaired or affected
without the consent of such Holder.

                  Section 5.11. Application of Money Collected. If the Trustee
collects any money pursuant to this Article, it shall pay out the money in the
following order, at the date or dates fixed by the Trustee and, in case of the
distribution of such money on account of principal, premium, if any, or
interest, upon presentation of the Securities and interest coupons, if any, and
the notation thereon of the payment if only partially paid and upon surrender
thereof if fully paid:

                  First:  to the Trustee for amounts due under Section 6.7;

                  Second: to Holders of Securities and interest coupons in
         respect of which or for the benefit of which such money has been
         collected for amounts due and unpaid on such Securities for principal
         of, premium, if any, and interest, ratably, without preference or
         priority of any kind, according to the amounts due and payable on such
         Securities for principal, premium, if any, and interest, respectively;
         and

                  Third:  the balance, if any, to the Company.

                  The Holders of each series of Securities denominated in ECU,
any other currency unit or a Foreign Currency and any matured interest coupons
relating thereto shall be entitled to receive a ratable portion of the amount
determined by the Trustee by


                                       57
<PAGE>   66
converting the principal amount Outstanding of such series of Securities and
matured but unpaid interest on such series of Securities in the currency in
which such series of Securities is denominated into Dollars at the Market
Exchange Rate as of the date of declaration of acceleration of Maturity of the
Securities.

                  The Trustee may fix a record date and payment date for any
payment to Holders pursuant to this Section 5.11. At least 15 days before such
record date, the Trustee shall mail to each Holder and the Company a notice that
states the record date, the payment date and the amount to be paid.

                  Section 5.12. 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 as though no such
proceeding had been instituted.

                  Section 5.13. Rights and Remedies Cumulative. Except as
otherwise provided with respect to the replacement or payment of mutilated,
destroyed, lost or stolen Securities in the last paragraph of Section 3.6, no
right or remedy herein conferred upon or reserved to the Trustee or the Holders
is intended to be exclusive of any other right or remedy, and every right and
remedy shall, to the extent permitted by law, be cumulative and in addition to
every other right and remedy given hereunder or now or hereafter existing at law
or in equity or otherwise. The assertion or employment of any right or remedy
hereunder, or otherwise, shall not prevent the concurrent assertion or
employment of any other appropriate right or remedy.

                  Section 5.14. Undertaking for Costs. In any suit for the
enforcement of any right or remedy under this Indenture, or in any suit against
the Trustee for any action taken, 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, however,
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 any Guarantor.

                  Section 5.15. Waiver of Stay, Extension or Usury Laws. Each of
the Company and the Guarantors 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
or any usury or other law wherever



                                       58
<PAGE>   67
enacted, now or at any time hereafter in force, which would prohibit or forgive
the Company from paying all or any portion of the principal, of, and premium, if
any, or interest on the Securities contemplated herein or in the Securities or
which may affect the covenants or the performance of this Indenture; and each of
the Company and the Guarantors (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.

                                    ARTICLE 6

                                   The Trustee

                  Section 6.1. Certain Duties and Responsibilities. The duties
and responsibilities of the Trustee shall be as provided by the Trust Indenture
Act. Notwithstanding the foregoing, no provision of this Indenture shall require
the Trustee to expend or risk its own funds or otherwise incur any financial
liability in the performance of any of its duties hereunder, or in the exercise
of any of its rights or powers, if it shall have reasonable grounds for
believing that repayment of such funds or adequate indemnity against such risk
or liability is not reasonably assured to it. Whether or not therein expressly
so provided, every provision of this Indenture relating to the conduct or
affecting the liability of or affording protection to the Trustee shall be
subject to the provisions of this Section.

                  Section 6.2. Notice of Defaults. If a default occurs hereunder
with respect to Securities of any series, the Trustee shall give the Holders of
Securities of such series notice of such default as and to the extent provided
by the Trust Indenture Act; provided, however, that in the case of any default
of the character specified in Section 5.1(3) with respect to Securities of such
series, no such notice to Holders shall be given until at least 30 days after
the occurrence thereof. For the purpose of this Section, the term "default"
means any event which is, or after notice or lapse of time or both would become,
an Event of Default with respect to Securities of such series.

                  Section 6.3. Certain Rights of Trustee. Subject to the
provisions of Section 6.1:

                  (1) the Trustee may rely and shall be protected in acting or
         refraining from acting upon any resolution, certificate, statement,
         instrument, opinion, report, notice, request, direction, consent,
         order, bond, debenture, note, other evidence of indebtedness or other
         paper or document believed by it to be genuine and to have been signed
         or presented by the proper party or parties;




                                       59
<PAGE>   68
                  (2) any request or direction of the Company mentioned herein
         shall be sufficiently evidenced by a Company Request or Company Order,
         and any resolution of the Board of Directors shall be sufficiently
         evidenced by a Board Resolution;

                  (3) whenever in the administration of this Indenture the
         Trustee shall deem it desirable that a matter be proved or established
         prior to taking, suffering or omitting any action hereunder, the
         Trustee (unless other evidence be herein specifically prescribed) may,
         in the absence of bad faith on its part, rely upon an Officers'
         Certificate;

                  (4) the Trustee may consult with counsel and the written
         advice of such counsel or any Opinion of Counsel shall be full and
         complete authorization and protection in respect of any action taken,
         suffered or omitted by it hereunder in good faith and in reliance
         thereon;

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

                  (6) the Trustee shall not be bound to make any investigation
         into the facts or matters stated in any resolution, certificate,
         statement, instrument, opinion, report, notice, request, direction,
         consent, order, bond, debenture, note, other evidence of indebtedness
         or other paper or document, but the Trustee, in its discretion, may
         make such further inquiry or investigation into such facts or matters
         as it may see fit, and, if the Trustee shall determine to make such
         further inquiry or investigation, it shall be entitled to examine the
         books, records and premises of the Company, personally or by agent or
         attorney;

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

                  (8) except with respect to Section 9.1, the Trustee shall have
         no duty to inquire as to the performance by the Company or any
         Guarantor of the covenants set forth in Article 9 beyond its good faith
         review of any certificates or other notices received by it from the
         Company or any Guarantor.

                  Section 6.4. Not Responsible for Recitals or Issuance of
Securities. The recitals contained herein and in the Securities and in the
Senior Subordinated Guarantees


                                       60
<PAGE>   69
endorsed thereon, except the Trustee's certificates of authentication, shall be
taken as the statements of the Company or the Guarantors, as the case may be,
and neither the Trustee nor any Authenticating Agent assumes any responsibility
for their correctness. The Trustee makes no representations as to the validity
or sufficiency of this Indenture or of the Securities or the Senior Subordinated
Guarantees endorsed thereon. Neither the Trustee nor any Authenticating Agent
shall be accountable for the use or application by the Company of Securities or
the proceeds thereof.

                  Section 6.5. May Hold Securities. The Trustee, any
Authenticating Agent, any Paying Agent, any Security Registrar or any other
agent of the Company, any Guarantor or the Trustee, in its individual or any
other capacity, may become the owner or pledgee of Securities and, subject to
Sections 6.8 and 6.13, may otherwise deal with the Company, any Guarantor and
any other obligor upon the Securities and the Senior Subordinated Guarantees
with the same rights it would have if it were not Trustee, Authenticating Agent,
Paying Agent, Security Registrar or such other agent.

                  Section 6.6. Money Held in Trust. Money held by the Trustee in
trust hereunder need not be segregated from other funds except to the extent
required by law. The Trustee shall be under no liability for interest on any
money received by it hereunder except as otherwise agreed with the Company or
any Guarantor, as the case may be.

                  Section 6.7. Compensation and Reimbursement. The Company
agrees

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

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

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

                  Section 6.8. Conflicting Interests. If the Trustee has or
shall acquire a conflicting interest within the meaning of the Trust Indenture
Act, the Trustee shall either


                                       61
<PAGE>   70
eliminate such interest or resign, to the extent and in the manner provided by,
and subject to the provisions of, the Trust Indenture Act and this Indenture. To
the extent permitted by such Act, the Trustee shall not be deemed to have a
conflicting interest by virtue of being a trustee under this Indenture with
respect to Securities of more than one series or a trustee under (i) the
Indenture dated as of May 15, 1997 between Allied and the Trustee relating to
the Allied's 11.30% Senior Discount Notes Due 2007, (ii) the Indenture dated as

                  Section 6.9. Corporate Trustee Required; Eligibility. There
shall at all times be a Trustee hereunder which shall be a Person that is
eligible pursuant to the Trust Indenture Act to act as such, has a combined
capital and surplus of at least $50,000,000 and has its Corporate Trust Office
located in the Borough of Manhattan, The City of New York. If such Person
publishes reports of condition at least annually, pursuant to law or to the
requirements of its supervising or examining authority, then for the purposes of
this Section, the combined capital and surplus of such Person shall be deemed to
be its combined capital and surplus as set forth in its most recent report of
condition so published. If at any time the Trustee shall cease to be eligible in
accordance with the provisions of this Section, it shall resign immediately in
the manner and with the effect hereinafter specified in this Article.

                  Section 6.10. Resignation and Removal; Appointment of
Successor. No resignation or removal of the Trustee and no appointment of a
successor Trustee pursuant to this Article shall become effective until the
acceptance of appointment by the successor Trustee in accordance with the
applicable requirements of Section 6.11.

                  The Trustee may resign at any time with respect to the
Securities of one or more series by giving written notice thereof to the
Company. If the instrument of acceptance by a successor Trustee required by
Section 6.11 shall not have been delivered to the Trustee within 30 days after
the giving of such notice of resignation, the resigning Trustee may petition any
court of competent jurisdiction for the appointment of a successor Trustee with
respect to the Securities of such series.

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

<PAGE>   71
                  If at any time:

                  (1) the Trustee shall fail to comply with Section 6.8 after
         written request therefor by the Company or by any Holder who has been a
         bona fide Holder of a Security for at least six months, or

                  (2) the Trustee shall cease to be eligible under Section 6.9
         and shall fail to resign after written request therefor by the Company
         or by any such Holder, or

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

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

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



                                       63
<PAGE>   72
removal of the Trustee with respect to the Securities of any series and each
appointment of a successor Trustee with respect to the Securities of any series
to all Holders of Securities of such series in the manner provided in Section
1.6. Each notice shall include the name of the successor Trustee with respect to
the Securities of such series and the address of its Corporate Trust Office.

                  Section 6.11. Acceptance of Appointment by Successor. In case
of the appointment hereunder of a successor Trustee with respect to all
Securities, every such successor Trustee so appointed shall execute, acknowledge
and deliver to the Company, the Guarantors and to the retiring Trustee an
instrument accepting such appointment, and thereupon the resignation or removal
of the retiring Trustee shall become effective and such successor Trustee,
without any further act, deed or conveyance, shall become vested with all the
rights, powers, trusts and duties of the retiring Trustee; but, on the request
of the Company or the successor Trustee, such retiring Trustee shall, upon
payment of its charges, execute and deliver an instrument transferring to such
successor Trustee all the rights, powers and trusts of the retiring Trustee and
shall duly assign, transfer and deliver to such successor Trustee all property
and money held by such retiring Trustee hereunder.

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


                                       64
<PAGE>   73
assign, transfer and deliver to such successor Trustee all property and money
held by such retiring Trustee hereunder with respect to the Securities of that
or those series to which the appointment of such successor Trustee relates.

                  Upon request of any such successor Trustee, the Company and
the Guarantors shall execute any and all instruments for more fully and
certainly vesting in and confirming to such successor Trustee all such rights,
powers and trusts referred to in the first or second preceding paragraph, as the
case may be.

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

                  Section 6.12. Merger, Conversion, Consolidation or Succession
to Business. Any corporation into which the Trustee may be merged or converted
or with which it may be consolidated, or any corporation resulting from any
merger, conversion or consolidation to which the Trustee shall be a party, or
any corporation succeeding to all or substantially all the corporate trust
business of the Trustee, shall be the successor of the Trustee hereunder,
provided such corporation shall be otherwise qualified and eligible under this
Article, without the execution or filing of any paper or any further act on the
part of any of the parties hereto. In case any Securities shall have been
authenticated, but not delivered, by the Trustee then in office, any successor
by merger, conversion or consolidation to such authenticating Trustee may adopt
such authentication and deliver the Securities so authenticated with the same
effect as if such successor Trustee had itself authenticated such Securities.

                  Section 6.13. Preferential Collection of Claims Against
Company. If and when the Trustee shall be or become a creditor of the Company,
any Guarantor (or any other obligor upon the Securities or the Senior
Subordinated Guarantees endorsed thereon), the Trustee shall be subject to the
provisions of the Trust Indenture Act regarding the collection of claims against
the Company (or any Guarantor or any such other obligor).

                  Section 6.14. Appointment of Authenticating Agent. The Trustee
may appoint an Authenticating Agent or Agents with respect to one or more series
of Securities which shall be authorized to act on behalf of the Trustee to
authenticate Securities of such series issued upon original issue and upon
exchange, registration of transfer or partial redemption thereof or pursuant to
Section 3.6, and Securities so authenticated and the Senior Subordinated
Guarantees endorsed thereon shall be entitled to the benefits of this Indenture
and shall be valid and obligatory for all purposes as if authenticated by the
Trustee hereunder. Wherever reference is made in this Indenture to the
authentication and delivery of Securities by the Trustee or the Trustee's
certificate of authentication, such reference shall be deemed to include
authentication and delivery on


                                       65
<PAGE>   74
behalf of the Trustee by an Authenticating Agent and a certificate of
authentication executed on behalf of the Trustee by an Authenticating Agent.
Each Authenticating Agent shall be acceptable to the Company and shall at all
times be a corporation organized and doing business under the laws of the United
States of America, any State thereof or the District of Columbia, authorized
under such laws to act as Authenticating Agent, having a combined capital and
surplus of not less than $50,000,000 and subject to supervision or examination
by Federal or State authority. If such Authenticating Agent publishes reports of
condition at least annually, pursuant to law or to the requirements of said
supervising or examining authority, then for the purposes of this Section, the
combined capital and surplus of such Authenticating Agent shall be deemed to be
its combined capital and surplus as set forth in its most recent report of
condition so published. If at any time an Authenticating Agent shall cease to be
eligible in accordance with the provisions of this Section, such Authenticating
Agent shall resign immediately in the manner and with the effect specified in
this Section.

                  Any corporation into which an Authenticating Agent may be
merged or converted or with which it may be consolidated, or any corporation
resulting from any merger, conversion or consolidation to which such
Authenticating Agent shall be a party, or any corporation succeeding to the
corporate agency or corporate trust business of an Authenticating Agent, shall
continue to be an Authenticating Agent, provided such corporation shall be
otherwise eligible under this Section, without the execution or filing of any
paper or any further act on the part of the Trustee or the Authenticating Agent.

                  An Authenticating Agent may resign at any time by giving
written notice thereof to the Trustee and to the Company. The Trustee may at any
time terminate the agency of an Authenticating Agent by giving written notice
thereof to such Authenticating Agent and to the Company. Upon receiving such a
notice of resignation or upon such a termination, or in case at any time such
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, the Trustee may appoint a successor Authenticating
Agent which shall be acceptable to the Company and shall give notice of such
appointment in the manner provided in Section 1.6 to all Holders of Securities
of the series with respect to which such Authenticating Agent will serve. Any
successor Authenticating Agent upon acceptance of its appointment hereunder
shall become vested with all the rights, powers and duties of its predecessor
hereunder, with like effect as if originally named as an Authenticating Agent.
No successor Authenticating Agent shall be appointed unless eligible under the
provisions of this Section.

                  The Trustee agrees to pay to each Authenticating Agent from
time to time reasonable compensation for its services under this Section, and
the Trustee shall be entitled to be reimbursed for such payments, subject to the
provisions of Section 6.7.

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

                  This is one of the Securities of the series designated therein
referred to in the within-mentioned Indenture.

Permitted. Neither the Company nor any Guarantor shall not consolidate with or
merge into, or sell, transfer, lease or otherwise dispose of its properties and
assets as, or substantially as, an entirety to, any Person unless:
    

   
                  (1) (A) the Company or the Guarantor, as the case may be, 
         will be the surviving entity or (B) the Person formed by or surviving
         any such consolidation or merger (if other than the Company or the
         Guarantor, as the case may be,), or to which such sale, transfer, lease
         or other disposition shall have been made, is an entity organized and
         existing under the laws of the United States, any State thereof or the
         District of Columbia;
    

   
                  (2) the Person formed by or surviving any such consolidation
         or merger (if other than the Company or the Guarantor, as the case may

         Indenture will remain in full force and effect as so supplemented;

         merger, sale, transfer, lease or other disposition, no Default or Event
         of Default exists; and
    

   
                  (4) with respect to any series of Securities, the Company
         satisfies such other conditions, if any, established with respect to
         such series of Securities pursuant to and in accordance with 
         Section 3.1.

                  The Company or the Guarantor, as the case may be, shall
deliver to the Trustee prior to the proposed consolidation, merger, sale,

effect and an Opinion of Counsel stating that the proposed consolidation,
merger, sale, transfer, lease or other disposition and such supplemental
indenture comply with this Indenture and that all conditions precedent to the
consummation of such transaction under this Section 7.1 have been met.

case may be, with, or merger of the Company or the Guarantor, as the case may

into an indenture or indentures supplemental hereto to add any provisions to or
to change in any manner or eliminate any provisions of this Indenture or of any
other indenture supplemental hereto or to modify in any manner the rights of the

Holder of each Outstanding Security affected thereby, an amendment under this
Section may not:

                  (1) change the Stated Maturity of the principal of, or
         premium, if any, on, or any installment of principal of or premium, if

         percentage or to provide that certain other provisions of this
         Indenture cannot be modified or waived with the consent of the Holders
         of each Outstanding Security affected thereby.

                  A supplemental indenture which changes or eliminates any
covenant or other provision of this Indenture which has expressly been included
solely for the benefit of one or more particular series of Securities, or which
modifies the rights of the Holders of Securities of such series with respect to
such covenant or other provision, shall be deemed not to affect the rights under
this Indenture of the Holders of Securities of any other series.

                  It is not necessary under this Section 8.2 for the Holders to
consent to the particular form of any proposed supplemental indenture, but it is
sufficient if they consent to the substance thereof.

                  Section 8.3. Compliance with Trust Indenture Act. Every
amendment to this Indenture or the Securities of one or more series shall be set
forth in a supplemental indenture that complies with the Trust Indenture Act as
then in effect.

                  Section 8.4. Execution of Supplemental Indentures. In
executing, or accepting the additional trusts created by, any supplemental
indenture permitted by this Article or the modification thereby of the trusts
created by this Indenture, the Trustee shall be entitled to receive, and
(subject to Section 6.1) shall be fully protected in relying upon, an Officers'
Certificate and 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 8.5. 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 Securities
theretofore or thereafter authenticated and delivered hereunder and of any
interest coupon appertaining thereto shall be bound thereby.

                  Section 8.6. Reference in Securities to Supplemental
Indentures. Securities, including any interest coupons, of any series
authenticated and delivered after


                                       71
<PAGE>   80
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 Securities including any interest coupons of any
series so modified as to conform, in the opinion of 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
Securities including any interest coupons of such series.

                  Section 8.7. Notice of Supplemental Indentures. Promptly after
the execution by the Company and the Trustee of any supplemental indenture
pursuant to the provisions of Section 8.2, the Company shall give notice thereof
to the Holders of each Outstanding Security affected, in the manner provided for
in Section 1.6, setting forth in general terms the substance of such
supplemental indenture. Any failure of the Company to give such notice, or any
defect therein, shall not, however, in any way impair or affect the validity of
any such supplemental indenture.

                                    ARTICLE 9

                                    Covenants

                  Section 9.1. Payment of Principal, Premium, if any, and
Interest. The Company covenants and agrees for the benefit of the Holders of
each series of Securities that it will duly and punctually pay the principal of,
premium, if any, and interest, together with additional amounts, if any, on the
Securities of that series in accordance with the terms of the Securities of such
series, any interest coupons appertaining thereto and this Indenture; provided,
however, that amounts properly withheld under the Internal Revenue Code of 1986,
as amended, by any Person from a payment to any Holder of Securities, after
having requested such Holder to provide applicable information that would allow
such Person to make such payment without withholding, shall be considered as
having been paid by the Company to such Holder for purposes of this Indenture.
An installment of principal, premium, if any, or interest shall be considered
paid on the date it is due if there shall have been sent to the Trustee or
Paying Agent by wire transfer, or if the Trustee or Paying Agent otherwise
holds, on that date money designated for and sufficient to pay the installment.

                  Section 9.2. Maintenance of Office or Agency. Unless otherwise
specified as contemplated by Section 3.1, if Securities of a series are issued
as Registered Securities, the Company will maintain in each Place of Payment for
any series of Securities an office or agency where Securities of that series may
be presented or surrendered for payment, where Securities of that series may be
surrendered for registration of transfer or exchange and where notices and
demands to or upon the Company or any Guarantor in respect of the Securities or
the Senior Guarantees of that series and this Indenture may be served. Unless
otherwise specified as contemplated by


                                       72
<PAGE>   81
Section 3.1, if Securities of a series are issuable as Bearer Securities, the
Company will maintain, (i) subject to any laws or regulations applicable
thereto, an office or agency in a Place of Payment for that series which is
located outside the United States where Securities of that series and related
interest coupons may be presented and surrendered for payment; provided,
however, that if the Securities of that series are listed on The International
Stock Exchange of the United Kingdom and the Republic of Ireland Limited, the
Luxembourg Stock Exchange or any other stock exchange located outside the United
States and such stock exchange shall so require, the Company will maintain a
Paying Agent for the Securities of that series in London, Luxembourg or any
other required city located outside the United States, as the case may be, so
long as the Securities of that series are listed on such exchange, and (ii)
subject to any laws or regulations applicable thereto, an office or agency in a
Place of Payment for that series which is located outside the United States,
where Securities of that series may be surrendered for exchange and where
notices and demands to or upon the Company in respect of the Securities of that
series and this Indenture may be served. The Company will give prompt written
notice to the Trustee of the location, and any change in the location, of any
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 and each
Guarantor hereby appoints the Trustee as its agent to receive all such
presentations, surrenders, notices and demands.

                  Unless otherwise specified as contemplated by Section 3.1, no
payment of principal, premium or interest on Bearer Securities shall be made at
any office or agency of the Company in the United States, by check mailed to any
address in the United States, by transfer to an account located in the United
States or upon presentation or surrender in the United States of a Bearer
Security or interest coupon for payment, even if the payment would be credited
to an account located outside the United States; provided, however, that, if the
Securities of a series are denominated and payable in Dollars, payment of
principal of and any premium or interest on any such Bearer Security shall be
made at the office of the Company's Paying Agent in the Borough of Manhattan,
The City of New York, if (but only if) payment in Dollars of the full amount of
such principal, premium or interest, as the case may be, at all offices or
agencies outside the United States maintained for the purpose by the Company in
accordance with this Indenture is illegal or effectively precluded by exchange
controls or other similar restrictions.

                  Unless otherwise specified as contemplated by Section 3.1, the
Company may also from time to time designate one or more other offices or
agencies where the Securities (including any interest coupons, if any) of one or
more series 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


                                       73
<PAGE>   82
manner relieve the Company of its obligation to maintain an office or agency in
each Place of Payment for Securities (including any interest coupons, if any) of
any series 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.

                  Unless otherwise specified as contemplated by Section 3.1, the
Trustee shall initially serve as Paying Agent.

                  Section 9.3. Money for Securities Payments to Be Held in
Trust; Unclaimed Money. If the Company shall at any time act as its own Paying
Agent with respect to any series of Securities and any interest coupons
appertaining thereto, it will, on or before each due date of the principal of,
premium, if any, or interest on any of the Securities of that series, segregate
and hold in trust for the benefit of the Persons entitled thereto a sum
sufficient to pay the principal, premium, if any, or interest so becoming due
until such sums shall be paid to such Persons or otherwise disposed of as herein
provided and will promptly notify the Trustee in writing of its action or
failure so to act.

                  Whenever the Company shall have one or more Paying Agents for
any series of Securities and any interest coupons appertaining thereto, it will,
prior to each due date of the principal of or any premium or interest on any
Securities of that series, deposit with a Paying Agent a sum sufficient to pay
such amount, such sum to be held as provided by the 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 for any series of
Securities other than the Trustee to execute and deliver to the Trustee an
instrument in which such Paying Agent shall agree with the Trustee, subject to
the provisions of this Section, that such Paying Agent will:

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

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

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

<PAGE>   83
                  The Company may at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture or for any other purpose, pay, or
by Company Order direct any Paying Agent to pay, to the Trustee all sums held in
trust by the Company or such Paying Agent, such sums to be held by the Trustee
upon the terms set forth in this Indenture; 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 any principal of or
premium or interest on any Security of any series and remaining unclaimed for
two years after such principal, premium, if any, 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 such Security
and interest coupon, if any, shall thereafter, as an unsecured general creditor,
look only to the Company for payment thereof, and all liability of the Trustee
or such Paying Agent with respect to such trust money, and all liability of the
Company as trustee thereof, shall thereupon cease; provided, however, that the
Trustee or such Paying Agent, before being required to make any such repayment,
may in the name and at the expense of the Company cause to be published once, in
an Authorized Newspaper in each Place of Payment with respect to such series, or
cause to be mailed to such Holder, notice that such money remains unclaimed and
that, after a date specified therein, which shall not be less than 30 days from
the date of such publication, any unclaimed balance of such money then remaining
will be repaid to the Company.

                  Section 9.4. Corporate Existence. Subject to Article 7, the
Company will at all times do or cause to be done all things necessary to
preserve and keep in full force and effect its corporate existence and its
rights and franchises; provided that nothing in this Section 9.4 shall prevent
the abandonment or termination of any right or franchise of the Company if it
shall be determined that such abandonment or termination is desirable in the
conduct of the business of the Company.

                  Section 9.5. Annual Review Certificate. The Company covenants
and agrees to deliver to the Trustee, within 120 days after the end of each
fiscal year of the Company, a certificate from the principal executive officer,
principal financial officer or principal accounting officer of the Company
stating that a review of the activities of the Company during such year and of
performance under this Indenture has been made under his or her supervision and
to the best of his or her knowledge, based on such review, each of the Company
and the Guarantors has fulfilled all of its obligations under this Indenture
throughout such year, or, if there has been a default in the fulfillment of any
such obligation, specifying each such default known to him or her and the nature
and status thereof. For purposes of this Section 9.7, such compliance shall be
determined without regard to any period of grace or requirement of notice
provided under this Indenture.

                  Section 9.6. Waiver of Certain Covenants. Except as otherwise
specified as contemplated by Section 3.1 for Securities of such series, the
Company or any Guarantor may, with respect to the Securities of any series, omit
in any particular instance to comply with any term, provision or condition set
forth in any covenant provided pursuant to Section 3.1(15), 8.1(7) of the
benefit of the Holders of such series if before the time for such compliance the
Holders of at least a majority in principal amount of the Outstanding Securities
of such series shall, by act of such Holders in accordance with Section 1.4,
either waive such compliance in such instance or generally waive compliance with
such term, provision or condition, but no such waiver shall extend to or affect
such term, provision or condition except to the extent so expressly waived, and,
until such waiver shall become effective, the obligations of the Company and
each of the Guarantors and the duties of the Trustee in respect of any such
term, provision or condition shall remain in full forth and effect.

                  (b) The Company shall file with the Trustee and the
Commission, in accordance with the rules and regulations prescribed from time to
time by the



                                       77

                                   Redemption

                  Section 11.1. Applicability of Article. Securities (including
interest coupons, if any) of any series which are redeemable before their Stated
Maturity shall be redeemable in accordance with their terms and (except as
otherwise specified as contemplated by Section 3.1 for Securities of any series)
in accordance with this Article.

                  Section 11.2. Election to Redeem; Notice to Trustee. The
election of the Company to redeem any Securities, including interest coupons, if
any, that, at the time of such election, may be redeemed at the option of the
Company, shall be evidenced by or pursuant to a Board Resolution. In the case of
any such redemption at the election of the Company of less than all the
Securities or interest coupons, if any, of any series, the Company shall, at
least 45 days prior to the Redemption Date fixed by the Company (unless a
shorter notice shall be satisfactory to the Trustee), notify the Trustee of such
Redemption Date, of the principal amount of Securities of such series to be
redeemed and, if applicable, of the tenor of the Securities to be redeemed. In
the case of any redemption of Securities (i) prior to the expiration of any
restriction on such redemption provided in the terms of such Securities or
elsewhere in this Indenture or (ii) pursuant to an election of the Company which
is subject to a condition specified in the terms of such Securities, the Company
shall furnish the Trustee with an Officers' Certificate evidencing compliance
with such restriction or condition.

                  Section 11.3. Selection of Securities to Be Redeemed. Unless
otherwise specified as contemplated by Section 3.1, if less than all the
Securities (including interest coupons, if any) of a series with the same terms
are to be redeemed, the Trustee, not more than 45 days prior to the Redemption
Date, shall select the Securities of the series to be redeemed in such manner as
the Trustee shall deem fair and appropriate. The Trustee shall make the
selection from Securities of the series that are Outstanding and that have not
previously been called for redemption and may provide for the selection for
redemption of portions (equal to the minimum authorized denomination for
Securities,


                                       78
<PAGE>   87
including interest coupons, if any, of that series or any integral multiple
thereof) of the principal amount of Securities, including interest coupons, if
any, of such series of a denomination larger than the minimum authorized
denomination for Securities of that series. The Trustee shall promptly notify
the Company in writing of the Securities selected by the Trustee for redemption
and, in the case of any Securities selected for partial redemption, the
principal amount thereof to be redeemed. If the Company shall so direct,
Securities registered in the name of the Company, any Affiliate or any
Subsidiary thereof shall not be included in the Securities selected for
redemption.

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

                  Section 11.4. Notice of Redemption. Unless otherwise specified
as contemplated by Section 3.1, notice of redemption shall be given in the
manner provided in Section 1.6 not less than 30 days nor more than 60 days prior
to the Redemption Date to the Holders of the Securities to be redeemed.

                  All notices of redemption shall state:

                  (1) the Redemption Date;

                  (2) the Redemption Price;

                  (3) if less than all the Outstanding Securities of a series
         are to be redeemed, the identification (and, in the case of partial
         redemption, the principal amounts) of the particular Security or
         Securities to be redeemed;

                  (4) the Place or Places of Payment where such Securities,
         together in the case of Bearer Securities with all interest coupons
         appertaining thereto, if any, maturing after the Redemption Date, are
         to be surrendered for payment of the Redemption Price;

                  (5) that Securities of the series called for redemption and
         all unmatured interest coupons, if any, appertaining thereto must be
         surrendered to the Paying Agent to collect the Redemption Price;

                  (6) that, on the Redemption Date, the Redemption Price will
         become due and payable upon each such Security, or the portion thereof,
         to be redeemed and, if applicable, that interest thereon will cease to
         accrue on and after said date;



                                       79
<PAGE>   88
                  (7) that the redemption is from a sinking fund, if such is the
         case;

                  (8) that, unless otherwise specified in such notice, Bearer
         Securities of any series, if any, surrendered for redemption must be
         accompanied by all interest coupons maturing subsequent to the
         Redemption Date or the amount of any such missing interest coupon or
         interest coupons will be deducted from the Redemption Price, unless
         security or indemnity satisfactory to the Company, the Trustee and any
         Paying Agent is furnished;

                  (9) the CUSIP number, if any, of the Securities;

                  (10) if applicable, the conversion or exchange price, the date
         on which the right to convert or exchange the Securities (or portions
         thereof to be redeemed) will terminate and the place or places where
         such Securities may be surrendered for conversion or exchange; and

                  (11) the procedures that a Holder must follow to surrender the
         Securities so to be redeemed.

Notice of redemption of Securities to be redeemed shall be given by the Company
or, at the Company's request, by the Trustee in the name and at the expense of
the Company.

                  Section 11.5. Deposit of Redemption Price. On or prior to any
Redemption Date, the Company shall deposit with the Trustee or with a Paying
Agent (or, if the Company is acting as its own Paying Agent, segregate and hold
in trust as provided in Section 9.3) an amount of money in the currency or
currencies (including currency unit or units) in which the Securities of such
series are payable (except as otherwise specified pursuant to Section 3.1 for
the Securities of such series) sufficient to pay on the Redemption Date the
Redemption Price of, and (unless the Redemption Date shall be an Interest
Payment Date) interest accrued to the Redemption Date on, all Securities or
portions thereof which are to be redeemed on that date.

                  Unless any Security by its terms prohibits any redemption
obligation from being satisfied by delivering and crediting Securities
(including Securities redeemed otherwise than through a sinking fund), the
Company may deliver such Securities to the Trustee for crediting of an amount
equal to the then applicable Redemption Price for such Securities against such
payment obligation in accordance with the terms of such Securities and this
Indenture.

                  Section 11.6. Securities Payable on Redemption Date. Notice of
redemption having been given as aforesaid, the Securities so to be redeemed
shall, on the Redemption Date, become due and payable at the Redemption Price
therein specified, and from and after such date (unless the Company shall
default in the payment of the



                                       80
<PAGE>   89
Redemption Price and accrued interest) such Securities shall cease to bear
interest and the interest coupons for any such interest appertaining to any
Bearer Security so to be redeemed, except to the extent provided below, shall be
void. Except as provided in the next succeeding paragraph, upon surrender of any
such Security, including interest coupons, if any, for redemption in accordance
with said notice, such Security shall be paid by the Company at the Redemption
Price, together with accrued interest to the Redemption Date; provided, however,
that installments of interest on Bearer Securities whose Stated Maturity is on
or prior to the Redemption Date shall be payable only at an office or agency
located outside the United States and its possessions (except as otherwise
provided in Section 9.2) and, unless otherwise specified as contemplated by
Section 3.1, only upon presentation and surrender of interest coupons for such
interest; and provided, further, that, unless otherwise specified as
contemplated by Section 3.1, installments of interest on Registered Securities
that are due and payable on Interest Payment Dates that are on or prior to the
Redemption Date shall be payable to the Holders of such Securities, or one or
more Predecessor Securities, registered as such at the close of business on the
relevant Regular Record Dates according to their terms and the provisions of
Section 3.7.

                  If any Bearer Security surrendered for redemption shall not be
accompanied by all appurtenant interest coupons maturing after the Redemption
Date, such Bearer Security may be paid after deducting from the Redemption Price
an amount equal to the face amount of all such missing interest coupons, or the
surrender of such missing interest coupon or interest coupons may be waived by
the Company and the Trustee if there be furnished to them such security or
indemnity as they may require to save each of them and any Paying Agent
harmless. If thereafter the Holder of such Bearer Security shall surrender to
the Trustee or any Paying Agent any such missing interest coupon in respect of
which a deduction shall have been made from the Redemption Price, such Holder
shall be entitled to receive the amount so deducted; provided, however, that
interest represented by interest coupons shall be payable only at an office or
agency located outside of the United States (except as otherwise provided
pursuant to Section 9.2) and, unless otherwise specified as contemplated by
Section 3.1, only upon presentation and surrender of those interest coupons.

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

                  Section 11.7. Securities Redeemed in Part. Upon surrender of a
Security that is redeemed in part at any Place of Payment therefor (with, if the
Company or the Trustee so required, 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 or her attorney duly authorized in writing), the
Company shall execute and the Trustee shall authenticate and deliver to the
Holder of that Security, without service charge, a new


                                       81
<PAGE>   90
Security or Securities (each with a Senior Guarantee of each Guarantor executed
by each such Guarantor and endorsed thereon) of the same series, having the same
form, terms and Stated Maturity, in any authorized denomination equal in
aggregate principal amount to the unredeemed portion of the principal amount of
the Security surrendered.

                                   ARTICLE 12

                                  Sinking Funds

                  Section 12.1. Applicability of Article. The provisions of this
Article shall be applicable to any sinking fund for the retirement of Securities
of a series except as otherwise specified as contemplated by Section 3.1 for
Securities of such series.

                  The minimum amount of any sinking fund payment provided for by
the terms of Securities of any series is herein referred to as a "mandatory
sinking fund payment," and any payment in excess of such minimum amount provided
for by the terms of Securities of any series is herein referred to as an
"optional sinking fund payment." If provided for by the terms of Securities of

                  Section 13.4. Quorum; Action. The Persons entitled to vote a
majority in principal amount of the Outstanding Securities of the applicable
series shall constitute a quorum. In the absence of a quorum within 30 minutes
of the time appointed for any such meeting, the meeting shall, if convened at

                  At the reconvening of any meeting adjourned for a lack of a
quorum pursuant to the preceding paragraph, the Persons entitled to vote 25% in
principal amount of the Outstanding Securities of the applicable series at the
time shall constitute a quorum for the taking of any action set forth in the
notice of the original meeting. Notice of the reconvening of a meeting adjourned
for lack of a quorum shall state expressly the percentage of the principal

                  At a meeting or an adjourned meeting duly reconvened and at
which a quorum is present as aforesaid, any resolution and all matters (except
as limited by the proviso to Section 8.2) shall be effectively passed and
decided if passed or decided by the Persons entitled to vote not less than the
lesser of (i) a majority in principal amount of Outstanding Securities of the
applicable series and (ii) 66 2/3% in principal amount of Outstanding Securities

                  In the event that any meeting shall be adjourned for lack of a

resolution or decision shall not be passed or taken because the Holders of the
percentage of Outstanding Securities of any series issuable as Bearer Securities
needed to approve such resolution or decision did not vote in favor of such
resolution or decision, the principal amount of Outstanding Securities of such
series represented at such meeting and voting in favor of such resolution or
decision may be counted for purposes of calculating whether the consent of the
Holders of the percentage of Outstanding Securities of such series needed in
order to make, give or take any request, demand, authorization, direction,
notice, consent, election, waiver or other action has been obtained, and such
vote shall constitute the consent thereto of such Holders.

Adjournment of Meetings. (a) Notwithstanding any other provisions of this
Indenture, the Trustee may make such reasonable regulations as it may deem
advisable for any meeting of Holders of Securities of any series issuable as

and of the appointment of proxies and in regard to the appointment and duties of
inspectors of votes, the submission and examination of proxies, certificates and
other evidence of the right to vote, and such other matters concerning the
conduct of the meeting as it shall deem appropriate. Except as otherwise
permitted or required by any such regulations, the holding of Securities of a
series issuable as Bearer Securities shall be proved in the manner specified in
Section 1.4 and the appointment of any proxy shall be provided in the manner
specified in Section 1.4 or by having the signature of the Person executing the
proxy witnessed or guaranteed by any trust company, bank or banker authorized by

other proof.

                  (b) The Trustee shall, by an instrument in writing, appoint a
temporary chairman (which may be a Responsible Officer of the Trustee) of the

of Securities of a series as provided in Section 13.2(b), in which case the
Company or the Holders of Securities of


                                       85

                  (c) At any meeting each Holder of a Security or proxy shall be
entitled to one vote for each U.S. $5,000 principal amount of Securities held or
represented by him or her; provided, however, that no vote shall be cast or
counted at any meeting in respect of any Security challenged as not Outstanding
and ruled by the chairman of the meeting to be not Outstanding. The chairman of
the meeting shall have no right to vote, except as a Holder of a Security or
proxy.

                  (d) Any meeting of Holders of Securities of a series issuable

of any series issuable as Bearer Securities shall be by written ballots on which

cast at the meeting. A record of the proceedings of each meeting of Holders of
Securities shall be prepared by the applicable secretary of the meeting and

this Article 14 shall be applicable to the Securities of any series which are
convertible or exchangeable into Equity Securities of the Company, and to the

Securities of such series.

                  (b) For purposes of this Article 14, the term "Equity
Securities" shall mean all or any of the following, authorized from time to
time: (i) the Company's Common Stock, $.01 par value (the "Common Stock"), (ii)

(a) In order to exercise a conversion or exchange privilege, the Holder of a
Security of a series with such privilege shall surrender such Security,
together, in the case of any Bearer Security, with all unmatured interest
coupons and any matured interest coupons in default appertaining thereto, to the
Company at the office or agency maintained for that purpose pursuant to Section
9.2, accompanied by written notice to the Company that the Holder elects to
convert or exchange such Security or a specified portion thereof. Such notice
shall also state, if different from the name and address of such Holder, the
name or names (with address) in which the certificate or certificates for Equity
Securities which shall be issuable on such conversion or exchange shall be
issued. Registered Securities surrendered for conversion or exchange shall (if
so required by the Company or the Trustee) be duly endorsed by or accompanied by
instruments of transfer in forms satisfactory to the Company and the Trustee

amount of such Security then being converted or exchanged, and such interest
shall be payable to such registered Holder on such Interest Payment Date
notwithstanding the conversion or exchange of such Security, subject to the
provisions of Section 3.7 relating to the payment of Defaulted Interest by the
Company.

<PAGE>   96
                  (c) As promptly as practicable after the receipt of such
notice and of any payment required pursuant to a Board Resolution and, subject
to Section 3.3, set forth, or determined in the manner provided, in an Officers'
Certificate, or established in one or more indentures supplemental hereto
setting forth the terms of such series of Security, and the surrender of such
Security in accordance with such reasonable regulations as the Company may

which such Security is surrendered, to such Holder or on its written order, a
certificate or certificates for the number of Equity Securities issuable upon
the conversion or exchange of such Security (or specified portion thereof), in
accordance with the provisions of such Board Resolution, Officers' Certificate
or supplemental indenture, and cash as provided therein in respect of any
fractional share of such Equity Security otherwise issuable upon such conversion
or exchange.

                  (d) Such conversion or exchange shall be deemed to have been
effected immediately prior to the close of business on the date on which such
notice and such payment, if required, shall have been received in proper order
for conversion or exchange by the Company and such Security shall have been
surrendered as aforesaid and at such time the rights of the Holder of such
Security as such Security Holder shall cease and the person or persons in whose
name or names any certificate or certificates for Equity Securities of the
Company shall be issuable upon such conversion or exchange shall be deemed to

thereby. Except as set forth above and subject to paragraph (d) of Section 3.7,
no payment or adjustment shall be made upon any conversion or exchange on
account of any interest accrued on the Securities surrendered for conversion or
exchange, or on account of any dividends on the Equity Securities of the Company
issued upon such conversion or exchange if the record date for the payment of
such dividends occurs prior to or on the date on which such conversion or
exchange shall be deemed to have been effected.

                  In the case of any Security which is converted or exchanged in
part only, upon such conversion or exchange the Company shall execute and the
Trustee shall authenticate and deliver to or on the order of the Holder thereof,
at the expense of the Company, a new Security or Securities of the same series,
of authorized denominations, in aggregate principal amount equal to the
unconverted or unexchanged portion of such Security.

                  Section 14.3. No Fractional Equity Securities. No fractional
Equity Security of the Company shall be issued upon conversions or exchanges of
Securities of any series. If more than one Security shall be surrendered for
conversion or exchange at one time by the same Holder, the number of full shares
of the Equity Security which shall be issuable upon conversion or exchange shall
be computed on the basis of the aggregate principal amount of the Securities (or
specified portions thereof to the extent permitted


                                       88
<PAGE>   97
hereby) so surrendered. If, except for the provisions of this Section 14.3, any
Holder of a Security or Securities would be entitled to a fractional share of
any Equity Security of the Company upon the conversion or exchange of such
Security or Securities, or specified portions thereof, the Company shall pay to
such Holder an amount in cash equal to the current market value of such
fractional share computed, (i) if such Equity Security is listed or admitted to
unlisted trading privileges on a national securities exchange, on the basis of
the last reported sale price regular way on the principal exchange where such
Equity Security is listed or admitted, on the last trading day prior to the date
of conversion or exchange upon which such a sale shall have been effected, (ii)

securities exchange but is quoted on the National Market System of the National
Association of Securities Dealers, Inc. ("NASDAQ"), on the basis of the average
of the bid and asked prices of such Equity Security on NASDAQ on the last
trading day prior to the date of conversion or exchange, (iii) if such Equity
Security is not at the time so listed or admitted to unlisted trading privileges
on a national securities exchange or quoted on NASDAQ, on the basis of the
average of the bid and asked prices of such Equity Security in the
over-the-counter market, on the last trading day prior to the date of conversion
or exchange, as reported by the National Quotation Bureau Incorporated or
similar organization if the National Quotation Bureau Incorporated is no longer
reporting such information, or (iv) in accordance with the terms of the
supplemental indenture or Board Resolutions setting the terms of the Securities
of such series. For purposes of this Section, "trading day" shall mean each
Monday, Tuesday, Wednesday, Thursday and Friday other than any day on which the
applicable Equity Security is not traded or quoted on a national securities
exchange, or if the applicable Equity Security is not traded or quoted on a
national securities exchange, on NASDAQ or the principal exchange or market on
which the applicable Equity Security is traded or quoted.

                  Section 14.4. Adjustment of Conversion or Exchange Price;
Consolidation or Merger. The conversion or exchange price of Securities of any
series that is convertible or exchangeable into an Equity Security of the

assets or other property into or for which such Securities may be converted or
exchanged as a result of any consolidation, merger, combination or similar
transaction shall be determined, in accordance with the terms of the
supplemental indenture or Board Resolutions setting the terms of the Securities

with the terms of the applicable Board Resolution or supplemental indenture and
shall prepare an Officers' Certificate setting forth the adjusted conversion or
exchange price and showing in reasonable detail the facts upon which such
adjustment is based. Whenever the securities, assets or other property into or
for which Securities of any series may be converted or


                                       89
<PAGE>   98
exchanged are changed as a result of any consolidation, merger or similar
transaction, the Company shall determine the nature and amount of such
securities, assets or other property in accordance with the terms of the
applicable Board Resolution or supplemental indenture and shall prepare an
Officer's Certificate describing such securities, assets or other property and
stating the amount of such securities, assets or other property into or for
which such Securities have become convertible or exchangeable. Such certificates
shall forthwith be filed at each office or agency maintained for the purpose of
conversion or exchange of Securities pursuant to Section 9.2 and, if different,
with the Trustee. The Company shall forthwith cause a notice setting forth the
adjusted conversion or exchange price or describing such securities, assets or
other property, as applicable, to be mailed, first class postage prepaid, to
each Holder of Registered Securities of such series at its address appearing on
the Register and to any conversion or exchange agent other than the Trustee.

exchangeable for any Equity Securities are Outstanding, in case:

Company is a party and for which approval of any stockholder of the Company is
required), or of the sale of all or substantially all of the assets of the
Company; or

the date on which a record is to be taken for the purpose of such dividend,

Exchange. The Company will pay any and all taxes that may be payable in respect
of the issue or delivery of its Equity Securities on conversion or exchange of

Security and of this Indenture. In case of the failure of the Company punctually
to make any such payment, each of Allied and the Subsidiary Guarantors hereby
jointly and severally agrees to cause such payment to be made punctually when
and as the same shall become due and payable, whether at the Stated Maturity or
by acceleration, call for redemption, purchase or otherwise, and as if such
payment were made by the Company.

                  Each of the Guarantors hereby jointly and severally agrees
that its obligations hereunder shall be unconditional, irrespective of the
validity, regularity or enforceability of any Security or this Indenture, the
absence of any action to enforce the same, any creation, exchange, release or
nonperfection of any Lien on any collateral for, or any release or amendment or
waiver of any term of any other Guarantee of, or any consent to departure from
any requirement of any other Guarantee, of all or any of the Securities, the
election by the Trustee or any of the Holders in any proceeding under Chapter 11
of Title 11 of the United States Code (the "Bankruptcy Code") of the application
of Section 1111(b)(2) of the Bankruptcy Code, any borrowing or grant of a


                                       92
<PAGE>   101
security interest by the Company, as debtor in possession, under Section 364 of
the Bankruptcy Code, the disallowance, under Section 502 of the Bankruptcy Code,
of all or any portion of the claims of the Trustee or any of the Holders for
payment of any of the Securities, any waiver or consent by the Holder of any
Security or by the Trustee with respect to any provisions thereof or of this
Indenture, the obtaining of any judgment against the Company or any action to
enforce the same or any other circumstances which might otherwise constitute a
legal or equitable discharge or defense of a guarantor. Each of the Guarantors
hereby waives the benefits of diligence, presentment, demand of payment, any
requirement that the Trustee or any of the Holders protect, secure, perfect or
insure any security interest in or other Lien on any property subject thereto or
exhaust any right or take any action against the Company or any other Person or
any collateral, filing of claims with a court in the event of insolvency or
bankruptcy of the Company, any right to require a proceeding first against the
Company, protest or notice with respect to any Security or the indebtedness
evidenced thereby and all demands whatsoever, and covenants, that this Senior
Guarantee will not be discharged in respect of any Security except by complete
performance of the obligations contained in such Security and in this Senior
Guarantee. Each of the Guarantors hereby agrees that, in the event of a default
in payment of principal (or premium, if any) or interest on any Security,
whether at its Stated Maturity or by acceleration, call for redemption, purchase
or otherwise, legal proceedings may be instituted by the Trustee on behalf of,
or by, the Holder of such Security, subject to the terms and conditions set
forth in this Indenture, directly against each of the Guarantors to enforce its
Senior Guarantee without first proceeding against the Company. Each Guarantor
agrees that if, after the occurrence and during the continuance of an Event of
Default, the Trustee or any of the Holders are prevented by applicable law from
exercising their respective rights to accelerate the maturity of the Securities,
to collect interest on the Securities or to enforce or exercise any other right
or remedy with respect to the Securities, or the Trustee or the Holders are
prevented from taking any action to realize on any collateral, such Guarantor
agrees to pay to the Trustee for the account of the Holders, upon demand
therefor, the amount that would otherwise have been due and payable had such
rights and remedies been permitted to be exercised by the Trustee or any of the
Holders.

                  No provision of any Senior Guarantee or Security or of the
Indenture shall alter or impair the Senior Guarantee of any Guarantor, which is
absolute and unconditional, of the due and punctual payment of the principal
(and premium, if any) and interest on the Security upon which such Senior
Guarantee is endorsed.

                  Each Guarantor shall be subrogated to all rights of the
Holders of the Securities upon which its Senior Guarantee is endorsed against
the Company in respect of any amounts paid by such Guarantor on account of such
Security pursuant to the provisions of its Senior Guarantee or this Indenture;
provided, however, that no Guarantor shall be entitled to enforce or to receive
any payments arising out of, or based upon, such


                                       93
<PAGE>   102
right of subrogation until the principal of (and premium, if any) and interest
on all Securities issued hereunder shall have been paid in full.

                  Each Senior Guarantee shall remain in full force and effect
and continue to be effective should any petition be filed by or against the
Company for liquidation or reorganization, should the Company become insolvent
or make an assignment for the benefit of creditors or should a receiver or
trustee be appointed for all or any significant part of the assets of the
Company and shall, to the fullest extent permitted by law, continue to be
effective or be reinstated, as the case may be, if at any time payment and
performance of the Securities is, pursuant to applicable law, rescinded or
reduced in amount, or must otherwise be restored or returned by any obligee on
the Securities, whether as a "voidable preference," "fraudulent transfer" or
otherwise, all as though such payment or performance had not been made. In the
event that any payment, or any part thereof, is rescinded, reduced, restored or
returned, the Securities shall, to the fullest extent permitted by law, be
reinstated and deemed reduced only by such amount paid and not so rescinded,
reduced, restored or returned.

                  No stockholder, officer, director, employer or incorporator,
past, present or future, of any Guarantor, as such, shall have any personal
liability under any Senior Guarantee by reason of his, her or its status as such
stockholder, officer, director, employer or incorporator.

                  To the extent that any Subsidiary Guarantor shall be required
to pay any amounts on account of the Securities pursuant to its Senior Guarantee
in excess of the greater of (i) the amount of the economic benefit actually
received by such Subsidiary Guarantor from the issuance of the Securities and
(ii) an amount calculated as the product of (A) the aggregate amount payable by
the Subsidiary Guarantors on account of the Securities pursuant to their Senior
Guarantees times (B) the proportion (expressed as a fraction) that such
Subsidiary Guarantor's net worth at the date enforcement of its Senior Guarantee
is sought bears to the aggregate net worth of all Subsidiary Guarantors at such
date, then such Subsidiary Guarantor shall be reimbursed by the other Subsidiary
Guarantors for the amount of such excess, pro rata, based upon the respective
net worth of such other Subsidiary Guarantors at the date enforcement of its
Senior Guarantees is sought. This paragraph is intended only to define the
relative rights of the Subsidiary Guarantors as among themselves, and nothing
set forth in this paragraph is intended to or shall impair the joint and several
obligations of the Guarantors under their respective Senior Guarantees.

                  The Guarantors shall have the right to seek contribution from
any nonpaying Guarantor so long as the exercise or such right does not impair
the rights of the Holders under any Senior Guarantee.

                  Section 15.2 Execution and Delivery of Senior Guarantees. The
Senior Guarantees to be endorsed on the Securities shall include the terms of
the Senior Guarantee set forth in Section 15.1 and any other terms that may be
set forth in the form established pursuant to Section 2.3. Each of the
Guarantors hereby agrees to execute its Senior Guarantee, in a form established
pursuant to Section 2.3, to be endorsed on each Security authenticated and
delivered by the Trustee.

                  The Senior Guarantee shall be executed on behalf of each
respective Guarantor by any one of such Guarantor's Chairman of the Board, Vice
Chairman of the Board, President or Vice Presidents, attested by its Secretary
or Assistant Secretary. The signature of any or all of these officers on the
Senior Guarantee may be manual or facsimile and may be pursuant to a duly
executed power of attorney.

                  A Senior Guarantee bearing the manual or facsimile signatures
of individuals who were at any time the proper officers of a Guarantor shall
bind such Guarantor, notwithstanding that such individuals or any of them have
ceased to hold such offices prior to the authentication and delivery of the
Security on which such Senior Guarantee is endorsed or did not hold such offices
at the date of such Senior Guarantee.

                  The delivery of any Security by the Trustee, after the
authentication thereof hereunder, shall constitute due delivery of the Senior
Guarantee endorsed thereon on behalf of the Guarantors. Each of the Guarantors
hereby jointly and severally agrees that its Senior Guarantee set forth in
Section 1301 shall remain in full force and effect notwithstanding any failure
to endorse a Senior Guarantee on any Security.

                  Section 15.3 Subsidiary Guarantors May Consolidate, Etc., on
Certain Terms. Except as may be provided in Section 15.4 and in Articles 7 and
9, nothing contained in this Indenture or in any of the Securities shall prevent
any consolidation or merger of a Subsidiary Guarantor with or into the Company
or a Guarantor or shall prevent any sale or conveyance of the property of a
Subsidiary Guarantor as an entirety or substantially as an entirety to the
Company or a Guarantor.

                  Section 15.4 Release of Guarantors. (a) Concurrently with any
consolidation or merger of a Subsidiary Guarantor or any sale or conveyance of
the property of a Subsidiary Guarantor as an entirety or substantially as an
entirety, in each case as permitted by Section 15.3, and upon delivery by the
Company to the Trustee of an Officers' Certificate and an Opinion of Counsel to
the effect that such consolidation, merger, sale or conveyance was made in
accordance with Section 15.3, the Trustee shall execute any documents reasonably
required in order to evidence the release of such Subsidiary Guarantor from its
obligations under its Subsidiary Guarantees endorsed on the Securities and under
this Article Thirteen. Any Subsidiary Guarantor not released from its
obligations under its Subsidiary Guarantees endorsed on the Securities and under



                                       95
<PAGE>   104
this Article 15 shall remain liable for the full amount of principal of (and
premium, if any) and interest on the Securities and for the other obligations of
a Subsidiary Guarantor under its Subsidiary Guarantees endorsed on the
Securities and under this Article 15.

                  (b) Concurrently with the defeasance of the Securities under
Section 4.4 or the covenant defeasance of the Securities under Section 4.5, the
Guarantors shall be released from all of their obligations under their Senior
Guarantees endorsed on the Securities and under this Article 15.

                  (c) Upon the consummation of any transaction (whether
involving a sale or other disposition of securities, a merger or otherwise)
whereby any Subsidiary Guarantor ceases to be a Restricted Subsidiary and which
transaction is otherwise in compliance with the provisions of this Indenture,
such Subsidiary Guarantor shall automatically be released from all obligations
under its Subsidiary Guarantees endorsed on the Securities and under this
Article 15.

                  Section 15.5. Additional Guarantors. The Company shall cause
each Person that becomes a Restricted Subsidiary after the date of this
Indenture [(other than Med Track)], upon becoming a Restricted Subsidiary, to
become a Subsidiary Guarantor with respect to the Securities. Any such Person
shall become a Subsidiary Guarantor by executing and delivering to the Trustee
(a) a supplemental indenture, in form and substance satisfactory to the Trustee,
which subjects such Person to the provisions of this Indenture as a Subsidiary
Guarantor and (b) an Opinion of Counsel to the effect that such supplemental
indenture has been duly authorized and executed by such Person and constitutes
the legal, valid, binding and enforceable obligation of such Person (subject to
such customary exceptions concerning creditors' rights and equitable principles
as may be acceptable to the Trustee in its discretion).

Company or of counsel may be based, insofar as it relates to accounting matters,
upon a certificate or opinion of or representations by an accountant or firm of
accountants in the employ of the Company, unless such officer or counsel, as the
case may be, knows, or in the exercise of reasonable care should know, that the
certificate or opinion or representations with respect to the accounting matters

electronic transmission, provided, in the case of an electronic transmission,
that it is transmitted through the facilities of a Depositary) by the Trustee
and, where it is hereby expressly required, to the Company. Such instrument or
instruments and record (and the action embodied therein and evidenced thereby)
are herein sometimes referred to as the "Act" of the Holders signing such
instrument or instruments or, in the case of Holders of Securities of a series
issuable as Bearer Securities, so voting at such meeting. The Company and the
Trustee may assume that any Act of a Holder has not been modified or revoked
unless written notice to the contrary is received prior to the time that the
action to which such Act relates has become effective. Proof of execution of any
such instrument or of a writing appointing any such agent shall be sufficient
for any purpose of this Indenture and (subject to Section 315 of the Trust
Indenture Act) conclusive in favor of the Trustee and the Company, if made in
the manner provided in this Section. The record of any meeting of Holders of
Securities issuable as Bearer Securities shall be proved in the manner provided
in Section 13.6.

                  (b) The fact and date of the execution by any Person of any
such instrument or writing and the authority of the Person executing the same
may be proved in any manner which the Trustee deems sufficient.

                  (c) The ownership of Bearer Securities may be proved by the
production of such Bearer Securities or by a certificate executed by any trust
company, bank, banker or other depository, wherever situated, if such
certificate shall be deemed by the Trustee to be satisfactory, showing that at
the date therein mentioned such Person had on deposit with such trust company,
bank, banker or other depository, or exhibited to it, the Bearer Securities
therein described; or such facts may be proved by the certificate or affidavit
of the Person holding such Bearer Securities, if such certificate or affidavit
is deemed by the Trustee to be satisfactory. The Trustee and the Company may
assume that such ownership of any Bearer Security continues until (i) another
such certificate or affidavit bearing a later date issued in respect of the same
Bearer Security is produced, (ii) such Bearer Security is produced to the
Trustee by some other Person, (iii) such Bearer Security is surrendered in
exchange for a Registered Security or (iv) such Bearer Security is no longer
Outstanding. The ownership of Bearer Securities may also be proved in any other
manner which the Trustee deems sufficient.

                  (d) The ownership of Registered Securities shall be proved by
the Register.

                  (e) Any request, demand, authorization, direction, notice,
consent, waiver or other Act of the Holder of any Security shall bind every
future Holder of the same Security and any interest coupons appertaining thereto
and the Holder of every Security or interest coupon 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 Act is made upon such Security
or interest coupon.

                  (f) If the Company shall solicit from the Holders any request,
demand, authorization, direction, notice, consent, waiver or other Act, the
Company may, at its option, by or pursuant to a Board Resolution, fix in advance
a record date for the determination of Holders of Registered Securities entitled
to give such request, demand, authorization, direction, notice, consent, waiver
or other Act, but the Company shall have no obligation to do so. Notwithstanding
Section 316(c) of the Trust Indenture Act, any such record date shall be the
record date specified in or pursuant to such Board Resolution, which shall be a
date not more than 30 days prior to the first solicitation of Holders generally
in connection therewith and no later than the date such first solicitation is
completed. If such a record date is fixed, such request, demand, authorization,
direction, notice, consent, waiver or other Act may be given before or after
such record date, but only the Holders of Registered Securities of record at the
close of business on such record date shall be deemed to be Holders for the
purposes of determining whether Holders of the requisite proportion of
Outstanding Securities have authorized or agreed or consented to such request,
demand, authorization, direction, notice, consent, waiver or other Act, and for
that purpose the Outstanding Securities shall be computed as of such record
date; provided that no such authorization, agreement or consent by the Holders
on such record date shall be deemed effective unless it shall become effective
pursuant to the provisions of this Indenture not later than six months after the
record date.

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

                  Section 1.5. Notices, Etc., to Trustee, Company and
Guarantors. 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,

                  (1) 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 Department, or at

         any other address previously furnished in writing to the Holders or the
         Company by the Trustee, or, with respect to notices by the Company,
         transmitted by facsimile transmission (confirmed by guaranteed
         overnight courier) to the following facsimile number: (612) 244-0711 or
         to any other facsimile number previously furnished in writing to the
         Company by the Trustee, or

                  (2) 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 it addressed to it at the address of the Company's
         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 or, with respect to notices by the Trustee, transmitted by
         facsimile transmission (confirmed by guaranteed overnight courier) to
         the following facsimile number: (602) 423-9424 or to any other
         facsimile number previously furnished in writing to the Trustee by the
         Company.

                  Section 1.6. Notice to Holders; Waiver. Where this Indenture
provides for notice to Holders of any event, (i) if any of the Securities
affected by such event are Registered Securities, such notice to the Holders
thereof shall be sufficiently given (unless otherwise herein expressly provided)
if in writing and mailed, first-class postage prepaid, to each such Holder
affected by such event, at his or her address as it appears in the Register,
within the time prescribed for the giving of such notice, and (ii) if any of the
Securities affected by such event are Bearer Securities, notice to the Holders
thereof shall be sufficiently given (unless otherwise herein or in the terms of
such Bearer Securities expressly provided) if published once in an Authorized
Newspaper in New York, New York, and in such other city or cities, if any, as
may be specified as contemplated by Section 3.1. Such notices shall be deemed to
have been given on the date of such mailing or publication.

                  In any case where notice to Holders is given by mail or by
publication, neither the failure to mail or publish such notice, nor any defect
in any notice so mailed or published, to any particular Holder shall affect the
sufficiency of such notice with respect to other Holders of Registered
Securities or of Bearer Securities. Any notice mailed to a Holder in the manner
herein prescribed shall be conclusively deemed to have been received by such
Holder, whether or not such Holder actually receives such notice.

                  If by reason of the suspension of regular mail service or by
reason of any other cause it shall be impracticable to give such notice as
provided above, then such notification as shall be made with the approval of the
Trustee shall constitute a sufficient notification for every purpose hereunder.
If it is impossible or, in the opinion of the Trustee, impracticable to give any
notice by publication in the manner herein required,



                                     - 18 -
<PAGE>   27
then such publication in lieu thereof as shall be made with the approval of the
Trustee shall constitute a sufficient publication of such notice.

                  Any request, demand, authorization, direction, notice, consent
or waiver required or permitted under this Indenture shall be in the English
language, except that any published notice may be in an official language of the
country of publication.

                  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 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 suspension of regular mail service or 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
sufficient notification for every purpose hereunder.

                  Section 1.7. Headings and Table of Contents. The Article and
Section headings herein and the Table of Contents are for convenience only and
shall not affect the construction hereof.

                  Section 1.8. Successor and Assigns. All covenants and
agreements in this Indenture by the Company or any Guarantor shall bind its
successors and assigns, whether so expressed or not.

                  Section 1.9. Separability. In case any provision of this
Indenture or the Securities or the Senior Subordinated Guarantees 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 1.10. Benefits of Indenture. Nothing in this
Indenture or in the Securities or the Senior Subordinated Guarantees, expressed
or implied, shall give to any Person, other than the parties hereto and their
successors hereunder and the Holders, any benefit or any legal or equitable
right, remedy or claim under this Indenture.

                  Section 1.11. Incorporators, Stockholders, Officers and
Directors of the Company Exempt from Individual Liability. No recourse under or
upon any obligation, covenant or agreement of or contained in this Indenture or
of or contained in any Security or interest coupon appertaining thereto, or for
any claim based thereon or otherwise in respect thereof, or because of any
indebtedness represented thereby, shall be had against any incorporator,
stockholder, officer or director, as such, past, present or future, of the
Company or any successor Person, either directly or through the Company or any

                                     - 19 -

successor Person, whether by virtue of any constitution, statute or rule of law,
by the enforcement of any assessment or penalty, by any legal or equitable
proceeding or otherwise; it being expressly understood that all such liability
is hereby expressly waived and released as a condition of the acceptance of, and
as a part of the consideration for the execution of this Indenture and the
issuance of, the Securities and any interest coupons appertaining thereto.

                  Section 1.12. Governing Law; Conflict with Trust Indenture Act
 . THIS INDENTURE, THE SECURITIES, THE SENIOR SUBORDINATED GUARANTEES ENDORSED
THEREON AND ANY INTEREST COUPONS APPERTAINING THERETO SHALL BE GOVERNED BY AND
CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK. This Indenture
is subject to the Trust Indenture Act and if any provision hereof limits,
qualifies or conflicts with the Trust Indenture Act, the Trust Indenture Act
shall control. Whether or not this Indenture is required to be qualified under
the Trust Indenture Act, the provisions of the Trust Indenture Act required to
be included in an indenture in order for such indenture to be so qualified shall
be deemed to be included in this Indenture with the same effect as if such
provisions were set forth herein and any provisions hereof which may not be
included in an indenture which is so qualified shall be deemed to be deleted or
modified to the extent such provisions would be required to be deleted or
modified in an indenture so qualified.

                  Section 1.13. Legal Holidays. In any case where any Interest
Payment Date, Redemption Date, sinking fund payment date, Stated Maturity or
Maturity of any Security shall not be a Business Day at any Place of Payment,
then (notwithstanding any other provision of this Indenture or of any Security
or interest coupon or any Senior Subordinated Guarantee other than a provision
in the Securities of any series which specifically states that such provision
shall apply in lieu of this Section), payment of principal, premium, if any, or
interest need not be made at such Place of Payment on such date, but may be made
on the next succeeding Business Day at such Place of Payment with the same force
and effect as if made on such date; provided that no interest shall accrue on
the amount so payable for the period from and after such Interest Payment Date,
Redemption Date, sinking fund payment date, Stated Maturity or Maturity, as the
case may be, if such amount is so paid on the next succeeding Business Day.

                  Section 1.14. Moneys of Different Currencies to Be Segregated.
The Trustee shall segregate all moneys, funds and accounts held by the Trustee
hereunder in one currency from any moneys, funds and accounts held by the
Trustee hereunder in one currency from any moneys, funds or accounts in any
other currencies, notwithstanding any provision herein which would otherwise
permit the Trustee to commingle such amounts.

                  Section 1.15. Independence of Covenants. All covenants and
agreements in this Indenture shall be given independent effect so that if a
particular action or condition is not permitted by any such covenant, the fact
that it would be permitted by an exception to, or be otherwise within the
limitations of, another covenant shall not avoid the occurrence of a Default or
an Event of Default if such action is taken or condition exists.

                  Section 1.16. Counterparts. This Indenture may be executed in
any number of counterparts, each of which shall be an original, but such
counterparts shall together constitute but one and the same instrument.

                SECURITY AND SENIOR SUBORDINATED GUARANTEE FORMS

                  Section 2.1. Forms Generally. The Securities of each series
and the interest coupons, if any, to be attached thereto and Senior Subordinated
Guarantees to be endorsed thereon shall be in substantially such form as shall
be established by or pursuant to a Board Resolution or in one or more indentures
supplemental hereto, in each case with such appropriate insertions, omissions,
substitutions and other variations as are required or permitted by this
Indenture, and may have such letters, numbers or other marks of identification
and such legends or endorsements placed thereon as may be required to comply
with the rules of any applicable securities exchange, organizational document,
governing instrument or law or as may, consistently herewith, be determined by
the officers executing such Securities and interest coupons, if any, or Senior
Subordinated Guarantees to be endorsed thereon, as the case may be, as evidenced
by their execution of the Securities and interest coupons, if any, or Senior
Subordinated Guarantees to be endorsed thereon, as the case may be. If temporary
Securities and Senior Subordinated Guarantees of any series are issued as
permitted by Section 3.4, the form thereof also shall be established as provided
in the preceding sentence. If the forms of Securities and interest coupons, if
any, and Senior Subordinated Guarantees of any series are established by, or by
action taken pursuant to, a Board Resolution, a copy of the Board Resolution
together with an appropriate record of any such action taken pursuant thereto,
including a copy of the approved form of Securities or interest coupons, if any,
and Senior Subordinated Guarantees shall be delivered to the Trustee at or prior
to the delivery of the Company Order contemplated by Section 3.3 for the

all as determined by the officers executing such Securities and interest

coupons, if any.

                  Section 2.2. Form of Trustee's Certificate of Authentication.
The Trustee's certificate of authentication shall be in substantially the
following form:

                                        as Trustee

                                        By:

                                                 Authorized Signatory

                  Section 2.3 Form of Senior Subordinated Guarantee

                          SENIOR SUBORDINATED GUARANTEE

                  For value received, each of the Guarantors named (or deemed
herein to be named) below hereby jointly and severally unconditionally
guarantees, on a senior subordinated basis to the Holder of the Security upon
which this Senior Subordinated Guarantee is endorsed, and to the Trustee on
behalf of such Holder, the due and punctual payment of the principal of (and
premium, if any) and interest on such Security when and as the same shall become
due and payable, whether at the Stated Maturity, by acceleration, call for
redemption, purchase or otherwise, according to the terms thereof and of the
Indenture referred to therein. In case of the failure of the Company punctually
to make any such payment, each of the Guarantors hereby jointly and severally
agrees to cause such payment to be made punctually when and as the same shall
become due and payable, whether at the Stated Maturity or by acceleration, call
for redemption, purchase or otherwise, and as if such payment were made by the
Company.

                  The Senior Subordinated Guarantee of each Guarantor shall be
subordinated in right of payment to the Senior Debt of such Guarantor as
provided in the Indenture.

                  Each of the Guarantors hereby jointly and severally agrees
that its obligations hereunder shall be unconditional, irrespective of the
validity, regularity or



                                     - 22 -
<PAGE>   31
enforceability of such Security or the Indenture, the absence of any action to
enforce the same, any creation, exchange, release or non-perfection of any Lien
on any collateral for, or any release or amendment or waiver of any term of any
other Guarantee of, or any consent to departure from any requirement of any
other Guarantee of, all or of any of the Securities, the election by the Trustee
or any of the Holders in any proceeding under Chapter 11 of the Bankruptcy Code
of the application of Section 1111(b)(2) of the Bankruptcy Code, any borrowing
or grant of a security interest by the Company, as debtor-in-possession, under
Section 364 of the Bankruptcy Code, the disallowance, under Section 502 of the
Bankruptcy Code, of all or any portion of the claims of the Trustee or any of
the Holders for payment of any of the Securities, any waiver or consent by the
Holder of such Security or by the Trustee or either of them with respect to any
provisions thereof or of the Indenture, the obtaining of any judgment against
the Company or any action to enforce the same or any other circumstances which
might otherwise constitute a legal or equitable discharge or defense of a
Guarantor. Each of the Guarantors hereby waives the benefits of diligence,
presentment, demand of payment, any requirement that the Trustee or any of the
Holders protect, secure, perfect or insure any security interest in or other
Lien on any property subject thereto or exhaust any right or take any action
against the Company or any other Person or any collateral, filing of claims with
a court in the event of insolvency or bankruptcy of the Company, any right to
require a proceeding first against the Company, protest or notice with respect
to such Security or the indebtedness evidenced thereby and all demands
whatsoever, and covenants that this Senior Subordinated Guarantee will not be
discharged except by complete performance of the obligations contained in such
Security and in this Senior Subordinated Guarantee. Each of the Guarantors
hereby agrees that, in the event of a default in payment of principal (or
premium, if any) or interest on such Security, whether at their Stated Maturity,
by acceleration, call for redemption, purchase or otherwise, legal proceedings
may be instituted by the Trustee on behalf of, or by, the Holder of such
Security, subject to the terms and conditions set forth in the Indenture,
directly against each of the Guarantors to enforce this Senior Subordinated
Guarantee without first proceeding against the Company. Each Guarantor agrees
that if, after the occurrence and during the continuance of an Event of Default,
the Trustee or any of the Holders are prevented by applicable law from
exercising their respective rights to accelerate the maturity of the Securities,
to collect interest on the Securities, or to enforce or exercise any other right
or remedy with respect to the Securities, such Guarantor agrees to pay to the
Trustee for the account of the Holders, upon demand therefor, the amount that
would otherwise have been due and payable had such rights and remedies been
permitted to be exercised by the Trustee or any of the Holders.

                  No reference herein to the Indenture and no provision of this
Senior Subordinated Guarantee or of the Indenture shall alter or impair the
Senior Subordinated Guarantee of any Guarantor, which is absolute and
unconditional, of the due and punctual



                                     - 23 -
<PAGE>   32
payment of the principal (and premium, if any) and interest on the Security upon
which this Senior Subordinated Guarantee is endorsed.

                  Each Guarantor shall be subrogated to all rights of the Holder
of such Security against the Company in respect of any amounts paid by such
Guarantor on account of such Security pursuant to the provisions of its Senior
Subordinated Guarantee or the Indenture; provided, however, that such Guarantor
shall not be entitled to enforce or to receive any payments arising out of, or
based upon, such right of subrogation until the principal of (and premium, if
any) and interest on this Security and all other Securities issued under the
Indenture shall have been paid in full.

                  This Senior Subordinated Guarantee shall remain in full force
and effect and continue to be effective should any petition be filed by or
against the Company for liquidation or reorganization, should the Company become
insolvent or make an assignment for the benefit of creditors or should a
receiver or trustee be appointed for all or any significant part of the
Company's assets, and shall, to the fullest extent permitted by law, continue to
be effective or be reinstated, as the case may be, if at any time payment and
performance of the Securities is, pursuant to applicable law, rescinded or
reduced in amount, or must otherwise be restored or returned by any obligee on
the Securities, whether as a "voidable preference," "fraudulent transfer" or
otherwise, all as though such payment or performance had not been made. In the
event that any payment, or any part thereof, is rescinded, reduced, restored or
returned, the Securities shall, to the fullest extent permitted by law, be
reinstated and deemed reduced only by such amount paid and not so rescinded,
reduced, restored or returned.

                  The Guarantors shall have the right to seek contribution from
any non-paying Guarantor so long as the exercise of such right does not impair
the rights of the Holders under this Senior Subordinated Guarantee.

                  The Guarantors or any particular Guarantor shall be released
from this Senior Subordinated Guarantee upon the terms and subject to certain
conditions provided in the Indenture.

                  By delivery of a supplemental indenture to the Trustee in
accordance with the terms of the Indenture, each Person that becomes a
Subsidiary Guarantor after the date of the Indenture will be deemed to have
executed and delivered this Subsidiary Guarantee for the benefit of the Holder
of the Security upon which this Subsidiary Guarantee is endorsed, with the same
effect as if such Subsidiary Guarantor was named below and had executed and
delivered this Subsidiary Guarantee.

                  All terms used in this Senior Subordinated Guarantee which are
defined in the Indenture referred to in the Security upon which this Senior
Subordinated Guarantee is endorsed shall have the meanings assigned to them in
such Indenture.

                  This Senior Subordinated Guarantee shall not be valid or
obligatory for any purpose until the certificate of authentication on the
Security upon which this Senior Subordinated Guarantee is endorsed shall have
been executed by the Trustee under the Indenture by manual signature.

                  Reference is made to Article Thirteen of the Indenture for
further provisions with respect to this Senior Subordinated Guarantee.

                  THIS SENIOR SUBORDINATED GUARANTEE SHALL BE GOVERNED BY AND
CONSTRUED IN ACCORDANCE WITH THE LAW OF THE STATE OF NEW YORK.

                  IN WITNESS WHEREOF, each of the Guarantors has caused this
Senior Subordinated Guarantee to be duly executed.

of oral or electronic instructions from the Company or its duly authorized
agents, promptly confirmed in writing) acceptable to the Trustee as may be
specified by or pursuant to a Company Order

                  (1) if the form or forms of such Securities and any interest
         coupons with Senior Subordinated Guarantees endorsed thereon have been
         established by or pursuant to a Board Resolution as permitted by
         Section 2.1, that such forms have been established in conformity with
         the provisions of this Indenture;

                  (2) if the terms of such Securities and any interest coupons
         have been, or, in the case of Securities of a series with Senior
         Subordinated Guarantees endorsed thereon offered in a Periodic
         Offering, will be, established by or pursuant to a Board Resolution as
         permitted by Section 3.1, that such terms have been, or, in the case of
         Securities of a series with Senior Subordinated Guarantees endorsed
         thereon offered in a Periodic Offering, will be, established in
         conformity with the provisions of this Indenture, subject, in the case
         of Securities with Senior Subordinated Guarantees endorsed thereon
         offered in a Periodic Offering, to any conditions specified in such
         Opinion of Counsel;

                  (3) if the form or terms of such Securities have been
         established in an indenture supplemental hereto, that such supplemental
         indenture has been duly authorized, executed and delivered by the
         Company and the Guarantors and, when duly authorized, executed and
         delivered by the Trustee, will constitute a legal, valid and binding
         obligation enforceable against the Company and the Guarantors in
         accordance with its terms, subject to (i) bankruptcy, insolvency,
         fraudulent transfer, reorganization, moratorium and other similar laws
         of general applicability relating to or affecting the enforcement of
         creditors' rights and to general principles of equity (regardless of
         whether enforcement is sought in a proceeding in equity or at law), and
         (ii) such other reasonable exceptions as may be specified in such
         Opinion of Counsel; and

                             (4) that such Securities, together with any
               interest coupons appertaining thereto, when issued by the Company
               and the Guarantors and authenticated and delivered by the Trustee
               in the manner and subject to any conditions specified in such
               Opinion of Counsel, will constitute valid and legally binding
               obligations of the Company and the Guarantors, enforceable
               against the Company and the Guarantors in accordance with their
               terms, subject to (i) bankruptcy, insolvency, fraudulent
               transfer, reorganization, moratorium and other similar laws of
               general applicability relating to or affecting the enforcement of
               creditors' rights and to general equity principles (regardless of
               whether enforcement is sought in a proceeding in equity or at
               law) and except further as enforcement thereof may be limited by
               (A) requirements that a claim with respect to any Securities or
               Senior Subordinated Guarantees denominated other than in Dollars
               (or a Foreign Currency or currency unit judgment in respect of
               such claim) be converted into Dollars at a rate of exchange
               prevailing on a date determined pursuant to applicable law or (B)
               governmental authority to limit, delay or prohibit the making of
               payments in Foreign Currencies or currency units or payments
               outside the United States, and (ii) such other reasonable
               exceptions as may be specified in such Opinion of Counsel; and

                  (ii) an Officers' Certificate stating that all conditions
precedent provided for in this Indenture relating to the issuance of such
Securities have been complied with and that, to the knowledge of the signers of
such certificate, no Event of Default with respect to such Securities shall have
occurred and be continuing.

                  Notwithstanding that such form or terms have been so
established, the Trustee shall have the right to decline to authenticate such
Securities if, in the opinion of the Trustee (after consultation with counsel),
the issue of such Securities pursuant to this Indenture will materially
adversely affect the Trustee's own rights, duties or immunities under this
Indenture or otherwise or if the Trustee determines that such authentication may
not lawfully be made.

                  Notwithstanding the provisions of Section 3.1 and of the two
preceding paragraphs, if all of the Securities of any series are not to be
issued at one time, it shall not be necessary to deliver the Officers'
Certificate otherwise required pursuant to Section 3.1 or the Company Order and
Opinion of Counsel otherwise required pursuant to the two preceding paragraphs
in connection with the authentication of each Security of such series if such
documents, with appropriate modifications to cover such future issuances, are
delivered at or prior to the authentication upon original issuance of the first
Security of such series to be issued.

                  With respect to Securities with Senior Subordinated Guarantees
endorsed thereon of a series offered in a Periodic Offering, the Trustee may
rely, as to the



                                     - 34 -
<PAGE>   43
authorization by the Company of any of such Securities and by the Guarantors of
any of such Senior Subordinated Guarantees endorsed thereon, the form and terms
thereof and the legality, validity, binding effect and enforceability thereof,
upon the Opinion of Counsel and the other documents delivered pursuant to
Sections 2.1 and 3.1 and this Section, as applicable, in connection with the
first authentication of Securities of such series.

                  If the Company shall establish pursuant to Section 3.1 that
the Securities of a series are to be issued in whole or in part in global form,
then the Company and the Guarantors shall execute and the Trustee shall, in
accordance with this Section and the Company Order with respect to such series,
authenticate and deliver one or more Securities with Senior Subordinated
Guarantees endorsed thereon in global form that (i) shall represent and shall be
denominated in an amount equal to the aggregate principal amount of the
Outstanding Securities of such series to be represented by such Security or
Securities in global form, (ii) shall be registered, if a Registered Security,
in the name of the Depositary for such Security or Securities in global form or
the nominee of such Depositary, (iii) shall be delivered by the Trustee to such
Depositary or pursuant to such Depositary's instruction and (iv) shall bear the
legend set forth in Section 2.5.

                  Each Depositary designated pursuant to Section 3.1 for a
Registered Security in global form must, at the time of its designation and at
all times while it serves as Depositary, be a clearing agency registered under
the Securities Exchange Act of 1934 and any other applicable statute or
regulation. If requested by the Company, the Trustee shall enter into an
agreement with a Depositary governing the respective duties and rights of such
Depositary and the Trustee with regard to Securities with Senior Subordinated
Guarantees endorsed thereon issued in global form.

                  Each Registered Security shall be dated the date of its
authentication and each Bearer Security shall be dated as of the date specified
pursuant to Section 3.1.

                  No Security or interest coupon appertaining thereto or Senior
Subordinated Guarantee endorsed thereon shall be entitled to any benefits under
this Indenture or be valid or obligatory for any purpose until authenticated by
the manual signature of one of the authorized signatories of the Trustee or an
Authenticating Agent and no interest coupon or Senior Subordinated Guarantee
shall be valid until the Security to which it appertains has been so
authenticated. Such signature upon any Security with Senior Subordinated
Guarantees endorsed thereon shall be conclusive evidence, and the only evidence,
that such Security and Senior Subordinated Guarantee has been duly authenticated
and delivered under this Indenture and is entitled to the benefits of this
Indenture. Except as permitted by Section 3.6 or 3.7, the Trustee shall not
authenticate and deliver any Bearer Security unless all appurtenant interest
coupons for interest then matured have been detached and cancelled.

                                     - 35 -
<PAGE>   44
                  Notwithstanding the foregoing, if any Security shall have been
authenticated and delivered hereunder but never issued and sold by the Company,
and the Company shall deliver such Security to the Trustee for cancellation as
provided in Section 3.9 together with a written statement (which need not comply
with Section 1.2 hereof and need not be accompanied by an Officers' Certificate
or an Opinion of Counsel) stating that such Security has never been issued and
sold by the Company, for all purposes of this Indenture such Security shall be
deemed never to have been authenticated and delivered hereunder and shall not be
entitled to the benefits of this Indenture.

                  Section 3.4. Temporary Securities. Pending the preparation of
definitive Securities of any series, the Company and the Guarantors may execute
and, upon Company Order, the Trustee shall authenticate and deliver temporary
Securities with Senior Subordinated Guarantees endorsed thereon of such series
which are printed, lithographed, typewritten, mimeographed or otherwise
produced, in any authorized denomination, substantially of the tenor and form,
with or without interest coupons, of the definitive Securities with Senior
Subordinated Guarantees endorsed thereon in lieu of which they are issued and
with such appropriate insertions, omissions, substitutions and other variations
as the officers executing such Securities and such Senior Subordinated
Guarantees may determine, as conclusively evidenced by their execution of such
Securities and interest coupons, if any and such Senior Subordinated Guarantees.
In the case of Securities of any series, such temporary Securities may be in
global form, representing all or a portion of the Outstanding Securities of such
series.

                  Except in the case of temporary Securities in global form,
each of which shall be exchanged in accordance with the provisions thereof, if
temporary Securities of any series are issued, the Company and the Guarantors
will cause definitive Securities with Senior Subordinated Guarantees endorsed
thereon of such series to be prepared without unreasonable delay. After
preparation of definitive Securities of such series, the temporary Securities of
such series shall be exchangeable for definitive Securities of such series upon
surrender of the temporary Securities of such series at the office or agency of
the Company pursuant to Section 9.2 in a Place of Payment for such series,
without charge to the Holder. Upon surrender for cancellation of any one or more
temporary Securities of any series (accompanied by any unmatured interest
coupons appertaining thereto), the Company and the Guarantors shall execute and
the Trustee shall authenticate and deliver in exchange therefor a like principal
amount of definitive Securities with Senior Subordinated Guarantees endorsed
thereon of the same series of authorized denominations and of like tenor;
provided, however, that no definitive Bearer Security shall be delivered in
exchange for a temporary Registered Security; and provided, further, that no
definitive Bearer Security shall be delivered in exchange for a temporary Bearer
Security unless such delivery shall occur only outside the United States. Until
so exchanged, the temporary Securities of any series shall in all respects be
entitled to the



                                     - 36 -
<PAGE>   45
same benefits under this Indenture as definitive Securities of such series
except as otherwise specified as contemplated by Section 3.1.

                  Section 3.5. Registration, Transfer and Exchange. The Company
shall cause to be kept at the Corporate Trust Office of the Trustee or in any
office or agency to be maintained by the Company in accordance with Section 9.2
in a Place of Payment a register (the "Register") in which, subject to such
reasonable regulations as it may prescribe, the Company shall provide for the
registration of Registered Securities and the registration of transfers of
Registered Securities. The Register shall be in written form or any other form
capable of being converted into written form within a reasonable time. The
Trustee is hereby initially appointed "Registrar" for the purpose of registering
Registered Securities and transfers of Registered Securities as herein provided.

                  Upon surrender for registration of transfer of any Registered
Security of any series at the office or agency maintained pursuant to Section
9.2 in a Place of Payment for that series, the Company and the Guarantors shall
execute, and the Trustee shall authenticate and deliver, in the name of the
designated transferee or transferees, one or more new Registered Securities with
Senior Subordinated Guarantees endorsed thereon of the same series, of any
authorized denominations and of a like aggregate principal amount and tenor and
containing identical terms and provisions.

                  Bearer Securities (except for any temporary global Bearer
Securities) or any interest coupons appertaining thereto (except for interest
coupons attached to any temporary global Bearer Security) shall be transferable
by delivery.

                  At the option of the Holder, Registered Securities of any
series (except a Registered Security in global form) may be exchanged for other
Registered Securities of the same series, of any authorized denominations, of a
like aggregate principal amount and tenor and containing identical terms and
provisions, upon surrender of the Registered Securities to be exchanged at such
office or agency. Whenever any Registered Securities are so surrendered for
exchange, the Company shall execute, and the Trustee shall authenticate and
deliver, the Registered Securities which the Holder making the exchange is
entitled to receive. Unless otherwise specified as contemplated by Section 3.1,
Bearer Securities may not be issued in exchange for Registered Securities.

                  Unless otherwise specified as contemplated by Section 3.1, at
the option of the Holder, Bearer Securities of such series may be exchanged for
Registered Securities (if the Securities of such series are issuable in
registered form) or Bearer Securities (if Bearer Securities of such series are
issuable in more than one denomination and such exchanges are permitted by such
series) of the same series, of any authorized denominations, of like aggregate
principal amount and tenor and containing identical terms and conditions, upon
surrender of the Bearer Securities to be exchanged at any such



                                     - 37 -
<PAGE>   46
office or agency, with all unmatured interest coupons and all matured interest
coupons in default thereto appertaining. If the Holder of a Bearer Security is
unable to produce any such unmatured interest coupon or coupons or matured
interest coupon or coupons in default, such exchange may be effected if the
Bearer Securities are accompanied by payment in funds acceptable to the Company
and the Trustee in an amount equal to the face amount of such missing interest
coupon or coupons, or the surrender of such missing interest coupon or interest
coupons may be waived by the Company, the Guarantors and the Trustee if there be
furnished to them such security or indemnity as they may require to save each of
them and any Paying Agent harmless. If thereafter the Holder of such Security
shall surrender to any Paying Agent any such missing interest coupon in respect
of which such a payment shall have been made, such Holder shall be entitled to
receive the amount of such payment; provided, however, that, except as otherwise
provided in Section 9.2, interest represented by interest coupons shall be
payable only upon presentation and surrender of those interest coupons at an
office or agency located outside the United States. Notwithstanding the
foregoing, in case any Bearer Security of any series is surrendered at any such
office or agency in exchange for a Registered Security of the same series after
the close of business at such office or agency on (i) any Regular Record Date
and before the opening of business at such office or agency on the relevant
Interest Payment Date, or (ii) any Special Record Date and before the opening of
business at such office or agency on the related date for payment of Defaulted
Interest, such Bearer Security shall be surrendered without the interest coupon
relating to such Interest Payment Date or proposed date of payment, as the case
may be (or, if such interest coupon is so surrendered with such Bearer Security,
such interest coupon shall be returned to the Person so surrendering the Bearer
Security), and interest or Defaulted Interest, as the case may be, will not be
payable on such Interest Payment Date or proposed date for payment, as the case
may be, in respect of the Registered Security issued in exchange for such Bearer
Security, but will be payable only to the Holder of such interest coupon, when
due in accordance with the provisions of this Indenture.

                  Notwithstanding anything herein to the contrary, the exchange
of Bearer Securities for Registered Securities shall be subject to applicable
laws and regulations in effect at the time of exchange. Neither the Company, the
Guarantors, the Trustee nor the Registrar shall exchange any Bearer Securities
for Registered Securities if it has received an Opinion of Counsel that as a
result of such exchange the Company would suffer adverse consequences under the
United States Federal income tax laws and regulations then in effect and the
Company has delivered to the Trustee a Company Order directing the Trustee not
to make such exchanges thereafter, unless and until the Trustee receives a
subsequent Company Order to the contrary. The Company shall deliver copies of
such Company Order to the Registrar.

                  Notwithstanding any other provision of this Section, unless
and until it is exchanged in whole or in part for Securities in certificated
form, a Security in global form



                                     - 38 -
<PAGE>   47
representing all or a portion of the Securities of a series may not be
transferred except as a whole by the Depositary for such series to a nominee of
such Depositary or by a nominee of such Depositary to such Depositary or another
nominee of such Depositary or by such Depositary or any such nominee to a
successor Depositary for such series or a nominee of such successor Depositary.

                  If at any time the Depositary for the Securities of a series
notifies the Company that it is unwilling or unable to continue as Depositary
for the Securities of such series or if at any time the Depositary for the
Securities of such series shall no longer be eligible under Section 3.3, the
Company shall appoint a successor Depositary with respect to the Securities of
such series. If a successor Depositary for the Securities of such series is not
appointed by the Company prior to the resignation of the Depositary and, in any
event, within 90 days after the Company receives such notice or becomes aware of
such ineligibility, the Company's designation of the Depositary pursuant to
Section 3.1(b)(23) shall no longer be effective with respect to the Securities
of such series and the Company and the Guarantors shall execute, and the
Trustee, upon receipt of a Company Order for the authentication and delivery of
certificated Securities with Senior Subordinated Guarantees endorsed thereon of
such series of like tenor, shall authenticate and deliver, Securities with
Senior Subordinated Guarantees endorsed thereon of such series of like tenor in
certificated form, in authorized denominations and in an aggregate principal
amount equal to the principal amount of the Security or Securities of such
series of like tenor in global form in exchange for such Security or Securities
in global form.

                  The Company may at any time in its sole discretion determine
that Securities issued in global form shall no longer be represented by such a
Security or Securities in global form. In such event the Company and the
Guarantors shall execute, and the Trustee, upon receipt of a Company Order for
the authentication and delivery of certificated Securities with Senior
Subordinated Guarantees endorsed thereon of such series of like tenor, shall
authenticate and deliver, Securities with Senior Subordinated Guarantees
endorsed thereon of such series of like tenor in certificated form, in
authorized denominations and in an aggregate principal amount equal to the
principal amount of the Security or Securities of such series of like tenor in
global form in exchange for such Security or Securities in global form.

                  If specified by the Company pursuant to Section 3.1 with
respect to a series of Securities, the Depositary for such series may surrender
a Security in global form of such series in exchange in whole or in part for
Securities of such series in certificated form on such terms as are acceptable
to the Company, the Guarantors and such Depositary. Thereupon, the Company and
the Guarantors shall execute, and the Trustee shall authenticate and deliver,
without service charge,

                                     - 39 -
<PAGE>   48
                  (i) to each Person specified by such Depositary a new
certificated Security or Securities with Senior Subordinated Guarantees endorsed
thereon of the same series of like tenor, of any authorized denomination as
requested by such Person in aggregate principal amount equal to and in exchange
for such Person's beneficial interest in the Security in global form; and

                  (ii) to such Depositary a new Security with Senior
Subordinated Guarantees endorsed thereon in global form of like tenor in a
denomination equal to the difference, if any, between the principal amount of
the surrendered Security in global form and the aggregate principal amount of
certificated Securities delivered to Holders thereof.

                  Upon the exchange of a Security with Senior Subordinated
Guarantees endorsed thereon in global form for Securities with Senior
Subordinated Guarantees endorsed thereon in certificated form, such Security
with Senior Subordinated Guarantees endorsed thereon in global form shall be
cancelled by the Trustee. Unless expressly provided with respect to the
Securities with Senior Subordinated Guarantees endorsed thereon of any series
that such Security with Senior Subordinated Guarantees endorsed thereon may be
exchanged for Bearer Securities, Securities with Senior Subordinated Guarantees
endorsed thereon in certificated form issued in exchange for a Security with
Senior Subordinated Guarantees endorsed thereon in global form pursuant to this
Section shall be registered in such names and in such authorized denominations
as the Depositary for such Security with Senior Subordinated Guarantees endorsed
thereon in global form, pursuant to instructions from its direct or indirect
participants or otherwise, shall instruct the Trustee in writing. The Trustee
shall deliver such Securities with Senior Subordinated Guarantees endorsed
thereon to the Persons in whose names such Securities with Senior Subordinated
Guarantees endorsed thereon are so registered.

                  Whenever any Securities are surrendered for exchange, the
Company and the Guarantors shall execute, and the Trustee shall authenticate and
deliver, the Securities with Senior Subordinated Guarantees endorsed thereon
which the Holder making the exchange is entitled to receive.

                  All Securities with Senior Subordinated Guarantees endorsed
thereon issued upon any registration of transfer or upon any exchange of
Securities with Senior Subordinated Guarantees thereon shall be the valid
obligations of the Company and the Guarantors, evidencing the same debt, and
entitled to the same benefits under this Indenture, as the Securities with
Senior Subordinated Guarantees endorsed thereon surrendered upon such
registration of transfer or exchange.

                  Every Registered Security presented or surrendered for
registration of transfer or for exchange shall (if so required by the Company,
the Guarantors, the



                                     - 40 -
<PAGE>   49
Registrar or the Trustee) be duly endorsed, or be accompanied by a written
instrument of transfer in form satisfactory to the Company, the Guarantors, the
Registrar and the Trustee 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 for any exchange of Securities, but the Company and the Guarantors
may require payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in connection with any registration or transfer or
exchange of Securities, other than exchanges pursuant to Section 3.4 or 11.7 not
involving any transfer.

                  The Company and the Guarantors shall not be required (i) to
issue, register the transfer of, or exchange any Securities with Senior
Subordinated Guarantees endorsed thereon for a period beginning at the opening
of business 15 days before any selection for redemption of Securities of like
tenor and of the series of which such Security is a part and ending at the close
of business on the earliest date on which the relevant notice of redemption is
deemed to have been given to all Holders of Securities of like tenor and of such
series to be redeemed; (ii) to register the transfer of or exchange any
Registered Security with Senior Subordinated Guarantees endorsed thereon so
selected for redemption, in whole or in part, except the unredeemed portion of
any Security being redeemed in part; or (iii) to exchange any Bearer Security
with Senior Subordinated Guarantees endorsed thereon so selected for redemption,
except that such a Bearer Security may be exchanged for a Registered Security of
that series and like tenor; provided that such Registered Security shall be
simultaneously surrendered for redemption.

                  The foregoing provisions relating to registration, transfer
and exchange may be modified, supplemented or superseded with respect to any
series of Securities by a Board Resolution or in one or more indentures
supplemental hereto.

                  Section 3.6. Replacement Securities. If a mutilated Security
or a Security with a mutilated interest coupon appertaining to it is surrendered
to the Trustee, together with, in proper cases, such security or indemnity as
may be required by the Company, the Guarantors or the Trustee to save each of
them harmless, the Company and the Guarantors shall execute and the Trustee
shall authenticate and deliver a replacement Registered Security with Senior
Subordinated Guarantees endorsed thereon, if such surrendered Security was a
Registered Security, or a replacement Bearer Security with Senior Subordinated
Guarantees endorsed thereon with interest coupons corresponding to the interest
coupons appertaining to the surrendered Security, if such surrendered Security
was a Bearer Security, of the same series and date of maturity.

                  If there shall be delivered to the Company, the Guarantors and
the Trustee (i) evidence to their satisfaction of the destruction, loss or theft
of any Security or



                                     - 41 -
<PAGE>   50
Security with a destroyed, lost or stolen interest coupon and (ii) such security
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 Security or interest coupon has been acquired by a bona fide
purchaser, the Company and the Guarantors shall execute and the Trustee shall
authenticate and deliver in lieu of any such destroyed, lost or stolen Security
or in exchange for the Security to which a destroyed, lost or stolen interest
coupon appertains (with all appurtenant interest coupons not destroyed, lost or
stolen), a replacement Registered Security with Senior Subordinated Guarantees
endorsed thereon, if such Holder's claim appertains to a Registered Security, or
a replacement Bearer Security with Senior Subordinated Guarantees endorsed
thereon with interest coupons corresponding to the interest coupons appertaining
to the destroyed, lost or stolen Bearer Security or the Bearer Security to which
such lost, destroyed or stolen interest coupon appertains, if such Holder's
claim appertains to a Bearer Security, of the same series and principal amount,
containing identical terms and provisions and bearing a number not
contemporaneously outstanding with interest coupons corresponding to the
interest coupons, if any, appertaining to the destroyed, lost or stolen
Security.

                  In case any such mutilated, destroyed, lost or stolen Security
or interest coupon has become or is about to become due and payable, the Company
and the Guarantors in their discretion may, instead of issuing a new Security or
interest coupon with Senior Subordinated Guarantees endorsed thereon, pay such
Security or interest coupon; provided, however, that payment of principal of and
any premium or interest on Bearer Securities shall, except as otherwise provided
in Section 9.2, be payable only at an office or agency located outside the
United States and, unless otherwise specified as contemplated by Section 3.1,
any interest on Bearer Securities shall be payable only upon presentation and
surrender of the interest coupons appertaining thereto.

                  Upon the issuance of any new Security under this Section, the
Company and the Guarantors 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, its agents
and counsel) connected therewith.

                  Every new Security with Senior Subordinated Guarantees
endorsed thereon of any series with its interest coupons, if any, issued
pursuant to this Section in lieu of any destroyed, lost or stolen Security, or
in exchange for a Security to which a destroyed, lost or stolen interest coupon
appertains, shall constitute an original additional contractual obligation of
the Company and the relevant Guarantor, whether or not the destroyed, lost or
stolen Security and its interest coupon, if any, or the destroyed, lost or
stolen interest coupon, shall be at any time enforceable by anyone, and shall be
entitled to all the



                                     - 42 -
<PAGE>   51
benefits of this Indenture equally and proportionately with any and all other
Securities of that series and their interest coupons, if any, 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 Securities or
interest coupons.

                  Section 3.7. Payment of Interest; Interest Rights Preserved.
(a) Unless otherwise provided as contemplated by Section 3.1, interest, if any,
on any Registered Security which is payable, and is punctually paid or duly
provided for, on any Interest Payment Date shall be paid to the Person in whose
name that Security (or one or more Predecessor Securities) is registered at the
close of business on the Regular Record Date for such interest at the office or
agency maintained for such purpose pursuant to Section 9.2; provided, however,
that at the option of the Company, interest on any series of Registered
Securities that bear interest may be paid (i) by check mailed to the address of
the Person entitled thereto as it shall appear on the Register of Holders of
Securities of such series or (ii) at the expense of the Company, by wire
transfer to an account maintained by the Person entitled thereto as specified in
the Register of Holders of Securities of such series.

                  Unless otherwise provided as contemplated by Section 3.1, (i)
interest, if any, on Bearer Securities shall be paid only against presentation
and surrender of the interest coupons for such interest installments as are
evidenced thereby as they mature and (ii) original issue discount, if any, on
Bearer Securities shall be paid only against presentation and surrender of such
Securities; in either case at the office of a Paying Agent located outside the
United States, unless the Company shall have otherwise instructed the Trustee in
writing, provided that any such instruction for payment in the United States
does not cause any Bearer Security to be treated as a "registration-required
obligation" under United States laws and regulations. The interest, if any, on
any temporary Bearer Security shall be paid, as to any installment of interest
evidenced by an interest coupon attached thereto only upon presentation and
surrender of such interest coupon and, as to other installments of interest,
only upon presentation of such Security for notation thereon of the payment of
such interest. If at the time a payment of principal of or interest, if any, on
a Bearer Security or interest coupon shall become due, the payment of the full
amount so payable at the office or offices of all the Paying Agents outside the
United States is illegal or effectively precluded because of the imposition of
exchange controls or other similar restrictions on the payment of such amount in
Dollars, then the Company may instruct the Trustee in writing to make such
payments at a Paying Agent located in the United States, provided that provision
for such payment in the United States would not cause such Bearer Security to be
treated as a "registration-required obligation" under United States laws and
regulations.

                                     - 43 -
<PAGE>   52
                  (b) Unless otherwise provided as contemplated by Section 3.1,
any interest on Securities of any series which is payable, but is not punctually
paid or duly provided for, on any Interest Payment Date in the case of
Registered Securities and upon presentation and surrender of the applicable
interest coupon in accordance with the second paragraph of Section 3.7(a) in the
case of Bearer Securities (herein called "Defaulted Interest"), shall forthwith
cease to be payable to the Holders on the relevant Regular Record Date by virtue
of their having been such Holders, and such Defaulted Interest may be paid by
the Company, at its election in each case, as provided in clause (1) or (2)
below:

                  (1) In the case of Registered Securities, the Company may
         elect to make payment of such Defaulted Interest to the Persons in
         whose names such Registered Securities (or their respective Predecessor
         Securities) are registered at the close of business on a Special Record
         Date for the payment of such Defaulted Interest, which shall be fixed
         in the following manner. The Company shall notify the Trustee in
         writing of the amount of Defaulted Interest proposed to be paid on each
         such Registered Security and the date of the proposed payment, and
         shall deposit with the Trustee an amount of money equal to the
         aggregate amount proposed to be paid in respect of such Defaulted
         Interest or shall make arrangements satisfactory to the Trustee for
         such deposit prior to the date of the proposed payment, such money when
         deposited to be held in trust for the benefit of the Persons entitled
         to such Defaulted Interest as in this clause (1) 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 of such Registered Securities at his or her
         address as it appears in the 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 such Registered Securities (or their respective Predecessor
         Securities) are registered at the close of business on such Special
         Record Date and shall no longer be payable pursuant to the following
         clause (2).

                  (2)(x) In the case of Registered Securities, the Company may
         make payment of such Defaulted Interest to the Persons in whose names
         such Registered Securities (or their respective Predecessor Securities)
         are registered at the close of business on a specified date in any

         precedent herein provided for relating to the satisfaction and

                  Notwithstanding the satisfaction and discharge of this
Indenture, the obligation of the Company to the Trustee and any predecessor
Trustee under Section 6.7, the obligations of the Company to any Authenticating
Agent under Section 6.13 and, if money shall have been deposited with the
Trustee pursuant to subclause (B) of clause (1) of this Section, the obligations
of the Trustee under Section 4.2, Section 9.2, the last paragraph of Section 9.3

                  Section 4.2. Application of Trust Funds. Subject to the
provisions of the last paragraph of Section 9.3, all money deposited with the
Trustee pursuant to Section 4.1 shall be held in trust and applied by it, in

Paying Agent) as the Trustee may determine, to the Persons entitled thereto, of
the principal, premium, if any and any interest for whose payment such money has
been deposited with or received by the Trustee, but such money need not be

the extent required by law.

Option to Effect Defeasance or Covenant Defeasance. Except as otherwise
specified as contemplated by Section 3.1 for the Securities of any series, the

Section 3.1 with respect to any series of Securities, shall be applicable to the
Securities and any interest coupons appertaining thereto.

                  Section 4.4. Defeasance and Discharge. On and after the date
on which the conditions set forth in Section 4.6 are satisfied with respect to
the Securities of or within any series, the Company shall be deemed to have paid
and been discharged from its obligations with respect to such Securities and any
interest coupons appertaining thereto (hereinafter "defeasance"). For this
purpose, such defeasance means that (i) the Company shall be deemed to have paid
and discharged the entire indebtedness represented by such Securities and any
interest coupons appertaining thereto which shall thereafter be deemed to be
"Outstanding" only for the purposes of Section 4.7 and the other Sections of
this Indenture referred to in clause (ii) of this Section, and to have satisfied
all its other obligations under such Securities and any interest coupons
appertaining thereto and this Indenture insofar as such Securities and any
interest coupons appertaining thereto are concerned (and the Trustee, upon
payment of all amounts due it under Section 6.7, at the expense of the Company,
shall on a Company Order execute proper instruments acknowledging the same) and
(ii) the Guarantors shall be released from all of their obligations under their
Senior Subordinated Guarantees and under Article 16 of this Indenture, except
the following which shall survive until otherwise terminated or discharged
hereunder: (i) the rights of Holders of such Securities and any interest coupons
appertaining thereto to receive, solely from the trust funds described in
Section 4.6(a) and as more fully set forth in such Section, payments in respect
of the principal of, premium, if any, and interest, if any, on such Securities
or any interest coupons appertaining thereto when such payments are due; (ii)
the Company's obligations with respect to such Securities under Sections 3.5,
3.6, 9.2 and 9.3 and with respect to the payment of additional amounts, if any,
payable with respect to such Securities as specified pursuant to Section
3.1(b)(16); (iii) the Company's obligations with respect to a conversion or
exchange of such Securities; (iv) the rights, powers, trusts, duties and
immunities of the Trustee hereunder and (v) this Article 4. Subject to
compliance with this Article 4, the Company may defease the Securities of any
series and any interest coupons appertaining thereto under this Section 4.4
notwithstanding a prior covenant defeasance (as defined herein) under Section
4.5 with respect to such Securities and any interest coupons appertaining
thereto. Following a defeasance, payment of such Securities may not be
accelerated because of an Event of Default.

                  Section 4.5. Covenant Defeasance. On and after the date on
which the conditions set forth in Section 4.6 (other than Section 4.6(c)) are
satisfied with respect to the Securities of or within any series, (i) the
Company shall be released from its obligations under Sections 7.1 and 9.4 and,
if specified pursuant to Section 3.1, its obligations under any other covenant,
with respect to such Securities and any interest coupons appertaining thereto
and (ii) the occurrence of any event specified in Sections 5.1(3) or 5.1(7)
(with respect to any of the obligations described in clause (i) above) or

                                      -50-
<PAGE>   59
5.1(4) shall be deemed not to be or result in a Default or Event of Default
(hereinafter, "covenant defeasance"), and such Securities and any interest
coupons appertaining thereto shall thereafter be deemed to be not "Outstanding"
for the purposes of any request, demand, authorization, direction, notice,
waiver, consent or declaration or Act of Holders (and the consequences of any
thereof) in connection with Section 7.1 or 9.4, such other covenant specified
pursuant to Section 3.1, or Section 5.1(4), but shall continue to be deemed
"Outstanding" for all other purposes hereunder. For this purpose, such covenant
defeasance means that, with respect to such Securities and any interest coupons
appertaining thereto, the Company may omit to comply with and shall have no
liability in respect of any term, condition or limitation set forth in any such
Section or such other covenant, whether directly or indirectly, by reason of any
reference elsewhere herein to any such Section or such other covenant or by
reason of reference in any such Section or such other covenant to any other
provision herein or in any other document and such omission to comply shall not
constitute a Default or an Event of Default under Section 5.1(3), 5.1(4) or
5.1(7) or otherwise, as the case may be, but, except as specified above, the
remainder of this Indenture and such Securities and any interest coupons
appertaining thereto shall be unaffected thereby.

                  Section 4.6. Conditions to Defeasance or Covenant Defeasance.
The following shall be the conditions to application of Section 4.4 or Section
4.5 to any Securities of or within a series and any interest coupons

                  (a) The Company shall have deposited or caused to be deposited
         irrevocably with the Trustee (or another trustee satisfying the
         requirements of Section 6.9 who shall agree to comply with, and shall
         be entitled to the benefits of, the provisions of Sections 4.3 through
         4.9 inclusive and the last paragraph of Section 9.3 applicable to the
         Trustee, for purposes of such Sections also a "Trustee") as trust funds
         in trust for the purpose of making the payments referred to in clauses
         (x) and (y) of this Section 4.6(a), specifically pledged as security
         for, and dedicated solely to, the benefit of the Holders of such
         Securities and any interest coupons appertaining thereto, with written
         instructions to the Trustee as to the application thereof, (A) money in
         an amount (in such currency, currencies or currency unit or units in
         which such Securities and any interest coupons appertaining thereto are
         then specified as payable at Maturity), or (B) if Securities of such
         series are not subject to repayment at the option of Holders,
         Government Obligations which through the payment of interest and
         principal in respect thereof in accordance with their terms will
         provide, not later than one day before the due date of any payment
         referred to in clause (x) or (y) of this Section 4.6(a), money in an
         amount or (C) a combination thereof in an amount, sufficient, in the
         opinion of a nationally recognized firm of independent certified public
         accountants or a nationally recognized investment banking firm
         expressed in a written certification thereof delivered to the Trustee,
         to pay and discharge, and which shall be applied

                                      -51-
<PAGE>   60
         by the Trustee to pay and discharge, (x) the principal of, premium, if
         any, and interest, if any, on such Securities and any interest coupons
         appertaining thereto on the Maturity of such principal or installment
         of principal or interest and (y) any mandatory sinking fund payments
         applicable to such Securities on the day on which such payments are due
         and payable in accordance with the terms of this Indenture and such
         Securities and any interest coupons appertaining thereto. Before such a
         deposit the Company may make arrangements satisfactory to the Trustee
         for the redemption of Securities at a future date or dates in
         accordance with Article 11 which shall be given effect in applying the
         foregoing.

                  (b) No Default or Event of Default with respect to the
         Securities of that series shall have occurred or be continuing on the
         date of such a deposit or shall occur as a result of such a deposit or,
         insofar as Sections 5.1(5) and (6) are concerned, shall occur at any
         time during the period ending on the 91st day after the date of such
         deposit (it being understood that this condition shall not be deemed
         satisfied until the expiration of such period).

                  (c) In the case of an election under Section 4.4, the Company
         shall have delivered to the Trustee an Officers' Certificate and an
         Opinion of Counsel to the effect that (i) the Company has received
         from, or there has been published by, the Internal Revenue Service a
         ruling, or (ii) since the date of execution of this Indenture, there
         has been a change in the applicable U.S. Federal income tax law, in
         either case to the effect that, and based thereon such opinion shall
         confirm that, the Holders of such Securities and any interest coupons
         appertaining thereto will not recognize income, gain or loss for U.S.
         Federal income tax purposes as a result of such defeasance and will be
         subject to U.S. Federal income tax on the same amount and in the same
         manner and at the same times, as would have been the case if such
         deposit, defeasance and discharge had not occurred.

                  (d) In the case of an election under Section 4.5, the Company
         shall have delivered to the Trustee an Officers' Certificate and an
         Opinion of Counsel to the effect that the Holders of such Securities
         and any interest coupons appertaining thereto will not recognize
         income, gain or loss for U.S. Federal income tax purposes as a result
         of such covenant defeasance and will be subject to U.S. Federal income
         tax on the same amount and in the same manner and at the same times, as
         would have been the case if such deposit and covenant defeasance had
         not occurred.

                  (e) The Company shall have delivered to the Trustee an
         Officers' Certificate and an Opinion of Counsel, each stating that all
         conditions precedent to the defeasance under Section 4.4 or the
         covenant defeasance under Section 4.5 (as the case may be) have been
         complied with.

         in compliance with any additional or substitute terms, conditions or
         limitations which may be imposed on the Company in connection therewith
         as contemplated by Section 3.1.

                  (g) At the time of such deposit: (A) no Default in the payment
         of principal of (or premium, if any) or interest on any Senior Debt
         shall have occurred and be continuing or (B) no other Event of Default
         with respect to any Senior Debt shall have occurred and be continuing
         and shall have resulted in such Senior Debt becoming or being declared
         due and payable prior to the date on which it would otherwise have
         become due and payable, or, in the case of either clause (A) or clause
         (B) above, each such Default or Event of Default shall have been cured
         or waived or shall have ceased to exist.

                  Section 4.7. Deposited Money and Government Obligations to Be
Held in Trust. Subject to the provisions of the last paragraph of Section 9.3,
all money and Government Obligations (or other property as may be provided
pursuant to Section 3.1) (including the proceeds thereof) deposited with the
Trustee pursuant to Section 4.6 in respect of any Securities of any series and
any interest coupons appertaining thereto shall be held in trust and applied by
the Trustee, in accordance with the provisions of such Securities and any
interest coupons appertaining thereto and this Indenture, to the payment, either
directly or through any Paying Agent (including the Company acting as its own
Paying Agent) as the Trustee may determine, to the Holders of such Securities
and any interest coupons appertaining thereto of all sums due and to become due
thereon in respect of principal, premium, if any, and interest, if any, but such
money need not be segregated from other funds except as provided herein and
except to the extent required by law.

Agent) shall promptly pay to the Company upon Company Request any excess money
or securities held by them at any time.

                  The provisions of the last paragraph of Section 9.3 shall
apply to any money or securities held by the Trustee or any Paying Agent under
this Article 4 that remain unclaimed for two years after the Maturity of any

                  Section 4.10. Reinstatement. If the Trustee (or Paying Agent)
is unable to apply any money or Government Obligations in accordance with
Section 4.6 by reason of any order or judgment of any court or governmental
authority enjoining, restraining or otherwise prohibiting such application, then
the Company's obligations under this Indenture and the Securities shall be
revived and reinstated, with present and prospective effect, as though no
deposit had occurred pursuant to Section 4.6, until such time as the Trustee (or
Paying Agent) is permitted to apply all such money or Government Obligations in
accordance with Section 4.6; provided, however, that if the Company makes any
payment to the Trustee (or Paying Agent) of principal, premium, if any, or
interest on any Security following the reinstatement of its obligations, the
Trustee (or Paying Agent) shall promptly pay any such amount to the Holders of
the Securities and the Company shall be subrogated to the rights of the Holders
of such Securities to receive such payment from the money and Government
Obligations held by the Trustee (or Paying Agent).

                              DEFAULTS AND REMEDIES

                  Section 5.1. Events of Default. An "Event of Default" occurs
with respect to the Securities of any series if (whatever the reason for such
Event of Default and whether it shall be voluntary or involuntary or be effected
by operation of law or pursuant to any judgment, decree or order of any court or
any order, rule or regulation of any administrative or governmental body):

                  (1) default in the payment of interest on any Security of that
         series or any interest coupon appertaining thereto or any additional
         amount payable with respect to any Security of that series as specified
         pursuant to Section 3.1(b)(16) when the same becomes due and payable
         and such default continues for a period of 30 days;

                  (2) default in the payment of any installment of the principal
         of or any premium on any Security of that series when the same becomes
         due and payable at its Maturity;

                  (3) failure by the Company or each Guarantor to comply with
         any of its agreements or covenants in, or any of the provisions of,
         this Indenture with respect to any Security of that series (other than
         an agreement, covenant or provision for which non-compliance is
         elsewhere in this Section specifically dealt with), and such
         non-compliance continues for a period of 90 days after there has been
         given, by registered or certified mail, return receipt requested, to
         the Company by the Trustee or to the Company and the Trustee by the
         Holders of at least 25% in

                                      -54-
<PAGE>   63
         aggregate principal amount of the Outstanding Securities of the series,
         a written notice specifying such default or breach and requiring it to
         be remedied and stating that such notice is a "Notice of Default"
         hereunder;

                  (4) default by the Company or any Guarantor under any
         mortgage, indenture or instrument under which there may be issued, or
         by which there may be secured or evidenced, any Debt (including this
         Indenture) having an aggregate principal amount outstanding of at least
         $25,000,000, whether such Debt now exists or shall hereafter be
         created, and, as a result of such default, such Debt shall become due
         and payable, whether by acceleration or otherwise, and such
         acceleration shall not be rescinded, annulled or cured within a period
         of 30 days after there has been given, by registered or certified mail,
         return receipt requested, to the Company by the Trustee or to the
         Company and the Trustee by the Holders of at least 25% in aggregate
         principal amount of the Outstanding Securities of that series a written
         notice specifying such default and requiring it to be remedied and
         stating that such notice is a "Notice of Default" hereunder (it being
         understood however, that the Trustee shall not be deemed to have
         knowledge of such default under such agreement or instrument unless a
         Responsible Officer of the Trustee shall have received written notice
         thereof from the Company, from any Holder, from the holder of any such
         Debt or from the trustee under any such agreement or other instrument);
         provided, however, that if such default under such mortgage, indenture
         or instrument is remedied or cured by the Company or waived by the
         holders of such Debt, then the Event of Default hereunder by reason
         thereof shall be deemed likewise to have been thereupon remedied, cured
         or waived without further action upon the part of either the Trustee or
         any of such Holders;

                  (5) the Company or any Guarantor pursuant to or within the
         meaning of any Bankruptcy Law (A) commences a voluntary case, (B)
         consents to the entry of an order for relief against it in an
         involuntary case, (C) consents to the appointment of a Custodian of it
         or for all or substantially all of its property, (D) makes a general
         assignment for the benefit of its creditors or (E) admits in writing
         its inability generally to pay its debts as they become due;

                  (6) a court of competent jurisdiction enters an order or
         decree under any Bankruptcy Law that (A) is for relief against the
         Company or any Guarantor in an involuntary case, (B) appoints a
         Custodian of the Company or any Guarantor or for all or substantially
         all of its property, or (C) orders the liquidation of the Company or
         any Guarantor, and such order or decree remains unstayed and in effect
         for 90 days; or

                  (7) there occurs any other Event of Default provided as
         contemplated by Section 3.1 with respect to Securities of that series.

<PAGE>   64
                  The term "Bankruptcy Law" means Title 11, United States
Bankruptcy Code of 1978, as amended, or any similar United States federal or
state law relating to bankruptcy, insolvency, receivership, reorganization or
relief of debtors or any amendment to, successor to or change in any such law.
The term "Custodian" means any receiver, trustee, assignee, liquidator,
custodian, sequestrator or similar official under any Bankruptcy Law.

                  Section 5.2. Acceleration; Rescission and Annulment. If an
Event of Default with respect to the Securities of any series at the time
Outstanding (other than an Event of Default specified in clause (5) or (6) of
Section 5.1) occurs and is continuing, the Trustee or the Holders of at least
25% in aggregate principal amount of all of the Outstanding Securities of that
series, by written notice received by the Company (and, if given by the Holders,
received by the Trustee), may declare the principal (or, if the Securities of
that series are Original Issue Discount Securities or Indexed Securities, such
portion of the principal amount as may be specified in the terms of that series)
of and accrued interest, if any, on all the Securities of that series to be due
and payable and upon any such declaration such principal (or, in the case of
Original Issue Discount Securities or Indexed Securities, such specified amount)
and interest, if any, shall be immediately due and payable, provided that the
payment of principal and interest on such Securities shall remain subordinated
to the extent provided in Article 15. If an Event of Default specified in clause
(5) or (6) of Section 5.1 with respect to the Securities of any series at the
time Outstanding occurs and is continuing, then the principal (or, if the
Securities of that series are Original Issue Discount Securities or Indexed
Securities, such portion of the principal amount as may be specified in the
terms of that series) of and accrued interest, if any, on all the Securities of
that series shall ipso facto be immediately due and payable without any
declaration or act on the part of the Trustee or any Holder of such Securities,
provided that the payment of principal and interest on such Securities shall
remain subordinated to the extent provided in Article 15.

                  At any time after such a declaration of acceleration with
respect to Securities of any series has been made and before a judgment or
decree for payment of the money due has been obtained by the Trustee as
hereinafter in this Article provided, the Holders of a majority in aggregate
principal amount of the Outstanding Securities of that series, by written notice
to the Trustee, may rescind and annul such declaration and its consequences if
all existing Defaults and Events of Default with respect to Securities of that
series, other than the non-payment of the principal of Securities of that series
which have become due solely by such declaration of acceleration, have been
cured or waived as provided in Section 5.7. No such rescission shall affect any
subsequent default or impair any right consequent thereon.

<PAGE>   65
                  Section 5.3. Collection of Indebtedness and Suits for
Enforcement by Trustee. The Company covenants that if

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

                  (2) default is made in the payment of the principal of (or
         premium, if any, on) any Security at the Maturity thereof, the Company
         will, upon demand of the Trustee, pay to it, for the benefit of the
         Holders of such Securities or interest coupons, if any, the whole
         amount then due and payable on such Securities for principal, premium,
         if any, and interest and, to the extent that payment of such interest
         shall be legally enforceable, interest on any overdue principal,
         premium, if any, and on any overdue interest, at the rate or rates
         prescribed therefor in such Securities or interest coupons, if any,
         and, in addition thereto, such further amount as shall be sufficient to
         cover the costs and expenses of collection, including all amounts due
         the Trustee, its agents and counsel under Section 6.7.

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

                  If an Event of Default with respect to Securities of any
series occurs and is continuing, the Trustee may in its discretion proceed to
protect and enforce its rights and the rights of the Holders of Securities of
such series by such appropriate judicial proceedings as the Trustee shall deem
most effectual to protect and enforce any such rights, whether for the specific
enforcement of any covenant or agreement in this Indenture or in aid of the
exercise of any power granted herein, or to secure any other proper remedy,
subject, however, to Section 5.8.

                  Section 5.4. Trustee May File Proofs of Claim. In case of any
judicial proceeding relative to the Company (or any Guarantor or any other
obligor upon the Securities), its property or its creditors (or of any Guarantor
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 the Trustee
allowed in any such proceeding. In particular, the Trustee shall be 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,

                                      -57-
<PAGE>   66
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 6.7.

                  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 of a Security or interest coupon any plan of reorganization, arrangement,
adjustment or composition affecting the Securities or the rights of any Holder
of a Security or interest coupon thereof or to authorize the Trustee to vote in
respect of the claim of any Holder of a Security or interest coupon in any such
proceeding; provided, however, that the Trustee may, on behalf of the Holders,
vote for the election of a trustee in bankruptcy or similar official and be a
member of a creditors' or other similar committee.

                  Section 5.5. Trustee May Enforce Claims Without Possession of
Securities. All rights of action and claims under this Indenture or the
Securities or the Senior Subordinated Guarantees may be prosecuted and enforced
by the Trustee without the possession of any of the Securities or the production
thereof in any proceeding relating thereto.

                  Section 5.6. Delay or Omission Not Waiver. No delay or
omission by the Trustee or any Holder of any Securities to exercise any right or
remedy accruing upon an Event of Default shall impair any such right or remedy
or constitute a waiver of or acquiescence in any such Event of Default.

                  Section 5.7. Waiver of Past Defaults. The Holders of not less
than a majority in aggregate principal amount of Outstanding Securities of any
series by written notice to the Trustee may waive on behalf of the Holders of
all Securities of such series and any interest coupons appertaining thereto a
past Default or Event of Default with respect to that series and its
consequences except (i) a Default or Event of Default in the payment of the
principal of, premium, if any, or interest on any Security of such series or any
interest coupon appertaining thereto or (ii) in respect of a covenant or
provision hereof which pursuant to Article 8 cannot be amended or modified
without the consent of the Holder of each Outstanding Security of such series
affected. Upon any such waiver, such Default shall cease to exist, and any Event
of Default arising therefrom shall be deemed to have been cured, for every
purpose of this Indenture but no such waiver shall extend to any subsequent or
other default or impair any right consequent thereon.

                  Section 5.8. Control by Majority. The Holders of not less than
a majority in aggregate principal amount of the Outstanding Securities of each
series

                                      -58-
<PAGE>   67
affected (with each such series voting as a class) shall have the right to
direct the time, method and place of conducting any proceeding for any remedy
available to the Trustee or exercising any trust or power conferred on it with
respect to Securities of that series; provided, however, that (i) the Trustee
may refuse to follow any direction that conflicts with any governmental rule or
law or this Indenture, (ii) the Trustee may refuse to follow any direction that
is unduly prejudicial to the rights of the Holders of Securities of such series
not consenting, or that would in the good faith judgment of the Trustee have a
substantial likelihood of involving the Trustee in personal liability without
adequate indemnity having been offered therefor and (iii) subject to Section
6.1, the Trustee may take any other action deemed proper by the Trustee which is
not inconsistent with such direction.

                  Section 5.9. Limitation on Suits by Holders. No Holder of any
Security of any series or any interest coupons appertaining thereto shall have
any right to institute any proceeding, judicial or otherwise, with respect to
this Indenture, or for the appointment of a receiver or trustee, or for any
other remedy hereunder, unless:

                  (1) the Holder has previously given written notice to the
         Trustee of a continuing Event of Default with respect to the Securities
         of that series;

                  (2) the Holders of at least 25% in aggregate principal amount
         of the Outstanding Securities of that series have made a written
         request to the Trustee to institute proceedings in respect of such
         Event of Default in its own name as Trustee hereunder;

                  (3) such Holder or Holders have offered to the Trustee
         indemnity satisfactory to the Trustee against any loss, liability or
         expense to be, or which may be, incurred by the Trustee in pursuing the
         remedy;

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

                  (5) during such 60-day period, the Holders of a majority in
         aggregate principal amount of the Outstanding Securities of that series
         have not given to the Trustee a direction inconsistent with such
         written request.

                  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 of such Holders, or to
obtain or to seek to obtain priority or preference over any other of such
Holders or to enforce any right under this Indenture, except in the manner
herein provided and for the equal and ratable benefit of all of such Holders.

                  Section 5.10. Rights of Holders to Receive Payment.
Notwithstanding any other provision of this Indenture, but subject to Section
9.2, the right of any Holder of a Security or interest coupon to receive payment
of principal of, premium, if any, and, subject to Sections 3.5 and 3.7, interest
on the Security, on or after the respective due dates expressed in the Security

an interest coupon to receive payment of interest due as provided in such
interest coupon, or to bring suit for the enforcement of any such payment on or
after such respective dates, and the right, if any, to convert or exchange such
Security in accordance with Article 14, shall not be impaired or affected
without the consent of such Holder.

                  Section 5.11. Application of Money Collected. If the Trustee
collects any money pursuant to this Article, it shall pay out the money in the
following order, at the date or dates fixed by the Trustee and, in case of the
distribution of such money on account of principal, premium, if any, or
interest, upon presentation of the Securities and interest coupons, if any, and
the notation thereon of the payment if only partially paid and upon surrender
thereof if fully paid:

                  First: to the Trustee for amounts due under Section 6.7;

                  Second: to Holders of Securities and interest coupons in
         respect of which or for the benefit of which such money has been
         collected for amounts due and unpaid on such Securities for principal
         of, premium, if any, and interest, ratably, without preference or
         priority of any kind, according to the amounts due and payable on such
         Securities for principal, premium, if any, and interest, respectively;
         and

                  Third: the balance, if any, to the Company.

                  The Holders of each series of Securities denominated in ECU,
any other currency unit or a Foreign Currency and any matured interest coupons
relating thereto shall be entitled to receive a ratable portion of the amount
determined by the Trustee by converting the principal amount Outstanding of such
series of Securities and matured but unpaid interest on such series of
Securities in the currency in which such series of Securities is denominated
into Dollars at the Market Exchange Rate as of the date of declaration of
acceleration of Maturity of the Securities.

                  The Trustee may fix a record date and payment date for any
payment to Holders pursuant to this Section 5.11. At least 15 days before such
record date, the Trustee shall mail to each Holder and the Company a notice that
states the record date, the payment date and the amount to be paid.

                  Section 5.12. 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 as though no such
proceeding had been instituted.

                  Section 5.13. Rights and Remedies Cumulative. Except as
otherwise provided with respect to the replacement or payment of mutilated,
destroyed, lost or stolen Securities in the last paragraph of Section 3.6, no
right or remedy herein conferred upon or reserved to the Trustee or the Holders
is intended to be exclusive of any other right or remedy, and every right and
remedy shall, to the extent permitted by law, be cumulative and in addition to
every other right and remedy given hereunder or now or hereafter existing at law
or in equity or otherwise. The assertion or employment of any right or remedy
hereunder, or otherwise, shall not prevent the concurrent assertion or
employment of any other appropriate right or remedy.

                  Section 5.14. Undertaking for Costs. In any suit for the
enforcement of any right or remedy under this Indenture, or in any suit against
the Trustee for any action taken, 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, however,
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 any Guarantor.

                  Section 5.15. Waiver of Stay, Extension or Usury Laws. Each of
the Company and the Guarantors 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
or any usury or other law wherever enacted, now or at any time hereafter in
force, which would prohibit or forgive the Company from paying all or any
portion of the principal, of, and premium, if any, or interest on the Securities
contemplated herein or in the Securities or which may affect the covenants or
the performance of this Indenture; and each of the Company and the Guarantors
(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.

                                   THE TRUSTEE

                  Section 6.1. Certain Duties and Responsibilities. The duties
and responsibilities of the Trustee shall be as provided by the Trust Indenture
Act. Notwithstanding the foregoing, no provision of this Indenture shall require
the Trustee to expend or risk its own funds or otherwise incur any financial
liability in the performance of any of its duties hereunder, or in the exercise
of any of its rights or powers, if it shall have reasonable grounds for
believing that repayment of such funds or adequate indemnity against such risk
or liability is not reasonably assured to it. Whether or not therein expressly
so provided, every provision of this Indenture relating to the conduct or
affecting the liability of or affording protection to the Trustee shall be
subject to the provisions of this Section.

                  Section 6.2. Notice of Defaults. If a default occurs hereunder
with respect to Securities of any series, the Trustee shall give the Holders of
Securities of such series notice of such default as and to the extent provided
by the Trust Indenture Act; provided, however, that in the case of any default
of the character specified in Section 5.1(3) with respect to Securities of such
series, no such notice to Holders shall be given until at least 30 days after
the occurrence thereof. For the purpose of this Section, the term "default"
means any event which is, or after notice or lapse of time or both would become,
an Event of Default with respect to Securities of such series.

                  Section 6.3. Certain Rights of Trustee. Subject to the
provisions of Section 6.1:

                  (1) the Trustee may rely and shall be protected in acting or
         refraining from acting upon any resolution, certificate, statement,
         instrument, opinion, report, notice, request, direction, consent,
         order, bond, debenture, note, other evidence of indebtedness or other
         paper or document believed by it to be genuine and to have been signed
         or presented by the proper party or parties;

                  (2) any request or direction of the Company mentioned herein
         shall be sufficiently evidenced by a Company Request or Company Order,
         and any resolution of the Board of Directors shall be sufficiently
         evidenced by a Board Resolution;

                  (3) whenever in the administration of this Indenture the
         Trustee shall deem it desirable that a matter be proved or established
         prior to taking, suffering or omitting any action hereunder, the
         Trustee (unless other evidence be herein specifically prescribed) may,
         in the absence of bad faith on its part, rely upon an Officers'
         Certificate;

<PAGE>   71

         thereon;

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

                  (6) the Trustee shall not be bound to make any investigation
         into the facts or matters stated in any resolution, certificate,
         statement, instrument, opinion, report, notice, request, direction,
         consent, order, bond, debenture, note, other evidence of indebtedness
         or other paper or document, but the Trustee, in its discretion, may
         make such further inquiry or investigation into such facts or matters
         as it may see fit, and, if the Trustee shall determine to make such

         including the costs and expenses of defending itself against any claim
         or liability in connection with the exercise or performance of any of
         its powers or duties hereunder.

                  Section 6.8. Conflicting Interests. If the Trustee has or
shall acquire a conflicting interest within the meaning of the Trust Indenture
Act, the Trustee shall either eliminate such interest or resign, to the extent
and in the manner provided by, and subject to the provisions of, the Trust

                  Section 6.9. Corporate Trustee Required; Eligibility. There

eligible pursuant to the Trust Indenture Act to act as such, has a combined
capital and surplus of at least $50,000,000 and has its Corporate Trust Office
located in the Borough of Manhattan, The City of New York. If such Person
publishes reports of condition at least annually, pursuant to law or to the
requirements of its supervising or examining authority, then for the purposes of
this Section, the combined capital and surplus of such Person shall be deemed to
be its combined capital and surplus as set forth in its most recent report of
condition so published. If at any time the Trustee shall cease to be eligible in
accordance with the provisions of this Section, it shall resign immediately in
the manner and with the effect hereinafter specified in this Article.

                  Section 6.10. Resignation and Removal; Appointment of
Successor. No resignation or removal of the Trustee and no appointment of a
successor Trustee pursuant to this Article shall become effective until the
acceptance of appointment by the successor Trustee in accordance with the
applicable requirements of Section 6.11.

                  The Trustee may resign at any time with respect to the
Securities of one or more series by giving written notice thereof to the
Company. If the instrument of acceptance by a successor Trustee required by
Section 6.11 shall not have been delivered to the Trustee within 30 days after
the giving of such notice of resignation, the resigning Trustee may petition any
court of competent jurisdiction for the appointment of a successor Trustee with
respect to the Securities of such series.

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

                  If at any time:

                  (1) the Trustee shall fail to comply with Section 6.8 after
         written request therefor by the Company or by any Holder who has been a
         bona fide Holder of a Security for at least six months, or

                  (2) the Trustee shall cease to be eligible under Section 6.9
         and shall fail to resign after written request therefor by the Company
         or by any such Holder, or

                                      -65-
<PAGE>   74
                  (3) the Trustee shall become incapable of acting or shall be
         adjudged a bankrupt or insolvent or a receiver of the Trustee or of its
         property shall be appointed or any public officer shall take charge or
         control of the Trustee or of its property or affairs for the purpose of
         rehabilitation, conservation or liquidation,

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

                  If the Trustee shall resign, be removed or become incapable of
acting, or if a vacancy shall occur in the office of Trustee for any cause, with
respect to the Securities of one or more series, the Company, by a Board
Resolution, shall promptly appoint a successor Trustee or Trustees with respect
to the Securities of that or those series (it being understood that any such
successor Trustee may be appointed with respect to the Securities of one or more
or all of such series and that at any time there shall be only one Trustee with
respect to the Securities of any particular series) and shall comply with the
applicable requirements of Section 6.11. If, within one year after such
resignation, removal or incapability, or the occurrence of such vacancy, a
successor Trustee with respect to the Securities of any series shall be
appointed by Act of the Holders of a majority in principal amount of the
Outstanding Securities of such series delivered to the Company and the retiring
Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance
of such appointment in accordance with the applicable requirements of Section
6.11, become the successor Trustee with respect to the Securities of such series
and to that extent supersede the successor Trustee appointed by the Company. If
no successor Trustee with respect to the Securities of any series shall have
been so appointed by the Company or the Holders and accepted appointment in the
manner required by Section 6.11, any Holder who has been a bona fide Holder of a
Security of such series for at least six months may, on behalf of himself and
all others similarly situated, petition any court of competent jurisdiction for
the appointment of a successor Trustee with respect to the Securities of such
series. The Company shall give notice of each resignation and each removal of
the Trustee with respect to the Securities of any series and each appointment of
a successor Trustee with respect to the Securities of any series to all Holders
of Securities of such series in the manner provided in Section 1.6. Each notice
shall include the name of the successor Trustee with respect to the Securities
of such series and the address of its Corporate Trust Office.

                  Section 6.11. Acceptance of Appointment by Successor. In case
of the appointment hereunder of a successor Trustee with respect to all
Securities, every such successor Trustee so appointed shall execute, acknowledge
and deliver to the Company,

                                      -66-
<PAGE>   75
the Guarantors and to the retiring Trustee an instrument accepting such
appointment, and thereupon the resignation or removal of the retiring Trustee
shall become effective and such successor Trustee, without any further act, deed
or conveyance, shall become vested with all the rights, powers, trusts and
duties of the retiring Trustee; but, on the request of the Company or the
successor Trustee, such retiring Trustee shall, upon payment of its charges,
execute and deliver an instrument transferring to such successor Trustee all the
rights, powers and trusts of the retiring Trustee and shall duly assign,
transfer and deliver to such successor Trustee all property and money held by
such retiring Trustee hereunder.

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

                  Upon request of any such successor Trustee, the Company and
the Guarantors shall execute any and all instruments for more fully and
certainly vesting in and confirming to such successor Trustee all such rights,
powers and trusts referred to in the first or second preceding paragraph, as the
case may be.

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

                  Section 6.12. Merger, Conversion, Consolidation or Succession
to Business. Any corporation into which the Trustee may be merged or converted
or with which it may be consolidated, or any corporation resulting from any
merger, conversion or consolidation to which the Trustee shall be a party, or
any corporation succeeding to all or substantially all the corporate trust
business of the Trustee, shall be the successor of the Trustee hereunder,
provided such corporation shall be otherwise qualified and eligible under this
Article, without the execution or filing of any paper or any further act on the
part of any of the parties hereto. In case any Securities shall have been
authenticated, but not delivered, by the Trustee then in office, any successor
by merger, conversion or consolidation to such authenticating Trustee may adopt
such authentication and deliver the Securities so authenticated with the same
effect as if such successor Trustee had itself authenticated such Securities.

                  Section 6.13. Preferential Collection of Claims Against
Company. If and when the Trustee shall be or become a creditor of the Company,
any Guarantor (or any other obligor upon the Securities or the Senior
Subordinated Guarantees endorsed thereon), the Trustee shall be subject to the
provisions of the Trust Indenture Act regarding the collection of claims against
the Company (or any Guarantor or any such other obligor).

                  Section 6.14. Appointment of Authenticating Agent. The Trustee
may appoint an Authenticating Agent or Agents with respect to one or more series
of Securities which shall be authorized to act on behalf of the Trustee to
authenticate Securities of such series issued upon original issue and upon
exchange, registration of transfer or partial redemption thereof or pursuant to
Section 3.6, and Securities so authenticated and the Senior Subordinated
Guarantees endorsed thereon shall be entitled to the benefits of this Indenture
and shall be valid and obligatory for all purposes as if authenticated by the
Trustee hereunder. Wherever reference is made in this Indenture to the
authentication and delivery of Securities by the Trustee or the Trustee's
certificate of authentication, such reference shall be deemed to include
authentication and delivery on behalf of the Trustee by an Authenticating Agent
and a certificate of authentication executed on behalf of the Trustee by an
Authenticating Agent. Each Authenticating Agent shall be acceptable to the
Company and shall at all times be a corporation organized and doing business
under the laws of the United States of America, any State thereof or the
District of Columbia, authorized under such laws to act as Authenticating Agent,
having a combined capital and surplus of not less than $50,000,000 and subject
to supervision or examination by Federal or State authority. If such
Authenticating Agent publishes reports of condition at least annually, pursuant
to law or to the requirements of said supervising or examining authority, then
for the purposes of this Section, the combined capital and

                                      -68-
<PAGE>   77
surplus of such Authenticating Agent shall be deemed to be its combined capital
and surplus as set forth in its most recent report of condition so published. If
at any time an Authenticating Agent shall cease to be eligible in accordance
with the provisions of this Section, such Authenticating Agent shall resign
immediately in the manner and with the effect specified in this Section.

                  Any corporation into which an Authenticating Agent may be
merged or converted or with which it may be consolidated, or any corporation
resulting from any merger, conversion or consolidation to which such
Authenticating Agent shall be a party, or any corporation succeeding to the
corporate agency or corporate trust business of an Authenticating Agent, shall
continue to be an Authenticating Agent, provided such corporation shall be
otherwise eligible under this Section, without the execution or filing of any
paper or any further act on the part of the Trustee or the Authenticating Agent.

                  An Authenticating Agent may resign at any time by giving
written notice thereof to the Trustee and to the Company. The Trustee may at any
time terminate the agency of an Authenticating Agent by giving written notice
thereof to such Authenticating Agent and to the Company. Upon receiving such a
notice of resignation or upon such a termination, or in case at any time such
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, the Trustee may appoint a successor Authenticating
Agent which shall be acceptable to the Company and shall give notice of such
appointment in the manner provided in Section 1.6 to all Holders of Securities
of the series with respect to which such Authenticating Agent will serve. Any
successor Authenticating Agent upon acceptance of its appointment hereunder
shall become vested with all the rights, powers and duties of its predecessor
hereunder, with like effect as if originally named as an Authenticating Agent.
No successor Authenticating Agent shall be appointed unless eligible under the
provisions of this Section.

                  The Trustee agrees to pay to each Authenticating Agent from
time to time reasonable compensation for its services under this Section, and
the Trustee shall be entitled to be reimbursed for such payments, subject to the
provisions of Section 6.7.

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

referred to in the within-mentioned Indenture.

Interest. The Company covenants and agrees for the benefit of the Holders of
each series of Securities that it will duly and punctually pay the principal of,
premium, if any, and interest, together with additional amounts, if any, on the
Securities of that series in accordance with the terms of the Securities of such

however, that amounts properly withheld under the Internal Revenue Code of 1986,
as amended, by any Person from a payment to any Holder of Securities, after

such Person to make such payment without withholding, shall be considered as
having been paid by the Company to such Holder for purposes of this Indenture.
An installment of principal, premium, if any, or interest shall be considered
paid on the date it is due if there shall have been sent to the Trustee or
Paying Agent by wire transfer, or if the Trustee or Paying Agent otherwise
holds, on that date money designated for and sufficient to pay the installment.

                  Section 9.2. Maintenance of Office or Agency. Unless otherwise
specified as contemplated by Section 3.1, if Securities of a series are issued

                                      -75-
<PAGE>   84
Securities, the Company will maintain in each Place of Payment for any series of
Securities an office or agency where Securities of that series may be presented
or surrendered for payment, where Securities of that series may be surrendered
for registration of transfer or exchange and where notices and demands to or
upon the Company or any Guarantor in respect of the Securities or the Senior
Subordinated Guarantees of that series and this Indenture may be served. Unless
otherwise specified as contemplated by Section 3.1, if Securities of a series

laws or regulations applicable thereto, an office or agency in a Place of
Payment for that series which is located outside the United States where
Securities of that series and related interest coupons may be presented and
surrendered for payment; provided, however, that if the Securities of that
series are listed on The International Stock Exchange of the United Kingdom and
the Republic of Ireland Limited, the Luxembourg Stock Exchange or any other
stock exchange located outside the United States and such stock exchange shall
so require, the Company will maintain a Paying Agent for the Securities of that
series in London, Luxembourg or any other required city located outside the
United States, as the case may be, so long as the Securities of that series are
listed on such exchange, and (ii) subject to any laws or regulations applicable
thereto, an office or agency in a Place of Payment for that series which is
located outside the United States, where Securities of that series may be
surrendered for exchange and where notices and demands to or upon the Company in
respect of the Securities of that series and this Indenture may be served. The
Company will give prompt written notice to the Trustee of the location, and any
change in the location, of any 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 and each Guarantor hereby appoints the Trustee as its
agent to receive all such presentations, surrenders, notices and demands.

                  Unless otherwise specified as contemplated by Section 3.1, no
payment of principal, premium or interest on Bearer Securities shall be made at
any office or agency of the Company in the United States, by check mailed to any
address in the United States, by transfer to an account located in the United
States or upon presentation or surrender in the United States of a Bearer
Security or interest coupon for payment, even if the payment would be credited
to an account located outside the United States; provided, however, that, if the
Securities of a series are denominated and payable in Dollars, payment of
principal of and any premium or interest on any such Bearer Security shall be
made at the office of the Company's Paying Agent in the Borough of Manhattan,
The City of New York, if (but only if) payment in Dollars of the full amount of
such principal, premium or interest, as the case may be, at all offices or
agencies outside the United States maintained

agencies where the Securities (including any interest coupons, if any) of one or
more series 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 each Place of Payment for
Securities (including any interest coupons, if any) of any series 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.

                  Unless otherwise specified as contemplated by Section 3.1, the
Trustee shall initially serve as Paying Agent.

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

                  Whenever the Company shall have one or more Paying Agents for
any series of Securities and any interest coupons appertaining thereto, it will,
prior to each due date of the principal of or any premium or interest on any
Securities of that series, deposit with a Paying Agent a sum sufficient to pay
such amount, such sum to be held as provided by the 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 for any series of
Securities other than the Trustee to execute and deliver to the Trustee an
instrument in which such Paying Agent shall agree with the Trustee, subject to
the provisions of this Section, that such Paying Agent will:

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

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

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

                  The Company may at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture or for any other purpose, pay, or
by Company Order direct any Paying Agent to pay, to the Trustee all sums held in
trust by the Company or such Paying Agent, such sums to be held by the Trustee
upon the terms set forth in this Indenture; 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 any principal of or
premium or interest on any Security of any series and remaining unclaimed for
two years after such principal, premium, if any, 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 such Security
and interest coupon, if any, shall thereafter, as an unsecured general creditor,
look only to the Company for payment thereof, and all liability of the Trustee
or such Paying Agent with respect to such trust money, and all liability of the
Company as trustee thereof, shall thereupon cease; provided, however, that the
Trustee or such Paying Agent, before being required to make any such repayment,
may in the name and at the expense of the Company cause to be published once, in
an Authorized Newspaper in each Place of Payment with respect to such series, or
cause to be mailed to such Holder, notice that such money remains unclaimed and
that, after a date specified therein, which shall not be less than 30 days from
the date of such publication, any unclaimed balance of such money then remaining
will be repaid to the Company.

Company will at all times do or cause to be done all things necessary to
preserve and keep in full force and effect its corporate existence and its
rights and franchises; provided that nothing in this Section 9.4 shall prevent
the abandonment or termination of any right or franchise of the Company if it
shall be determined that such abandonment or termination is desirable in the
conduct of the business of the Company.

                  Section 9.5. Annual Review Certificate. The Company covenants
and agrees to deliver to the Trustee, within 120 days after the end of each
fiscal year of the Company, a certificate from the principal executive officer,
principal financial officer or principal accounting officer of the Company

in any particular instance to comply with any term, provision or condition set
forth in any covenant provided pursuant to Section 3.1(15), 8.1(2) or 8.1(7) for
the benefit of the Holders of such series if before the time for such compliance
the Holders of at least a majority in principal amount of the Outstanding
Securities of such series shall, by act of such Holders in accordance with
Section 1.4, either waive such compliance in such instance or generally waive
compliance with such term, provision or condition, but no such waiver shall
extend to or affect such term, provision or condition except to the extent so
expressly waived, and, until such waiver shall become effective, the obligations
of the Company and each of the Guarantors and the duties of the Trustee in
respect of any such term, provision or condition shall remain in full force and
effect.

interest coupons, if any) of any series which are redeemable before their Stated
Maturity shall be redeemable in accordance with their terms and (except as
otherwise specified as contemplated by Section 3.1 for Securities of any series)
in accordance with this Article.

                  Section 11.2. Election to Redeem; Notice to Trustee. The
election of the Company to redeem any Securities, including interest coupons, if
any, that, at the time of such election, may be redeemed at the option of the
Company, shall be evidenced by or pursuant to a Board Resolution. In the case of
any such redemption at the election of the Company of less than all the
Securities or interest coupons, if any, of any series, the Company shall, at
least 45 days prior to the Redemption Date fixed by the Company (unless a
shorter notice shall be satisfactory to the Trustee), notify the Trustee of such
Redemption Date, of the principal amount of Securities of such series to be
redeemed and, if applicable, of the tenor of the Securities to be redeemed. In
the case of any redemption of Securities (i) prior to the expiration of any
restriction on such redemption provided in the terms of such Securities or
elsewhere in this Indenture or (ii) pursuant to an election of the Company which
is subject to a condition specified in the terms of such

                                      -81-
<PAGE>   90
Securities, the Company shall furnish the Trustee with an Officers' Certificate
evidencing compliance with such restriction or condition.

                  Section 11.3. Selection of Securities to Be Redeemed. Unless
otherwise specified as contemplated by Section 3.1, if less than all the
Securities (including interest coupons, if any) of a series with the same terms
are to be redeemed, the Trustee, not more than 45 days prior to the Redemption
Date, shall select the Securities of the series to be redeemed in such manner as
the Trustee shall deem fair and appropriate. The Trustee shall make the
selection from Securities of the series that are Outstanding and that have not
previously been called for redemption and may provide for the selection for
redemption of portions (equal to the minimum authorized denomination for
Securities, including interest coupons, if any, of that series or any integral
multiple thereof) of the principal amount of Securities, including interest
coupons, if any, of such series of a denomination larger than the minimum
authorized denomination for Securities of that series. The Trustee shall
promptly notify the Company in writing of the Securities selected by the Trustee
for redemption and, in the case of any Securities selected for partial
redemption, the principal amount thereof to be redeemed. If the Company shall so
direct, Securities registered in the name of the Company, any Affiliate or any
Subsidiary thereof shall not be included in the Securities selected for
redemption.

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

                  Section 11.4. Notice of Redemption. Unless otherwise specified
as contemplated by Section 3.1, notice of redemption shall be given in the
manner provided in Section 1.6 not less than 30 days nor more than 60 days prior
to the Redemption Date to the Holders of the Securities to be redeemed.

                  All notices of redemption shall state:

                  (1) the Redemption Date;

                  (2) the Redemption Price;

                  (3) if less than all the Outstanding Securities of a series
         are to be redeemed, the identification (and, in the case of partial
         redemption, the principal amounts) of the particular Security or
         Securities to be redeemed;

                  (4) the Place or Places of Payment where such Securities,
         together in the case of Bearer Securities with all interest coupons
         appertaining thereto, if any,

                                      -82-
<PAGE>   91
         maturing after the Redemption Date, are to be surrendered for payment
         of the Redemption Price;

                  (5) that Securities of the series called for redemption and
         all unmatured interest coupons, if any, appertaining thereto must be
         surrendered to the Paying Agent to collect the Redemption Price;

                  (6) that, on the Redemption Date, the Redemption Price will
         become due and payable upon each such Security, or the portion thereof,
         to be redeemed and, if applicable, that interest thereon will cease to
         accrue on and after said date;

                  (7) that the redemption is from a sinking fund, if such is the
         case;

                  (8) that, unless otherwise specified in such notice, Bearer
         Securities of any series, if any, surrendered for redemption must be
         accompanied by all interest coupons maturing subsequent to the
         Redemption Date or the amount of any such missing interest coupon or
         interest coupons will be deducted from the Redemption Price, unless
         security or indemnity satisfactory to the Company, the Trustee and any
         Paying Agent is furnished;

                  (9) the CUSIP number, if any, of the Securities;

                  (10) if applicable, the conversion or exchange price, the date
         on which the right to convert or exchange the Securities (or portions
         thereof to be redeemed) will terminate and the place or places where
         such Securities may be surrendered for conversion or exchange; and

                  (11) the procedures that a Holder must follow to surrender the
         Securities so to be redeemed.

                  Notice of redemption of Securities to be redeemed shall be
given by the Company or, at the Company's request, by the Trustee in the name
and at the expense of the Company.

                  Section 11.5. Deposit of Redemption Price. On or prior to any
Redemption Date, the Company shall deposit with the Trustee or with a Paying
Agent (or, if the Company is acting as its own Paying Agent, segregate and hold
in trust as provided in Section 9.3) an amount of money in the currency or
currencies (including currency unit or units) in which the Securities of such
series are payable (except as otherwise specified pursuant to Section 3.1 for
the Securities of such series) sufficient to pay on the Redemption Date the
Redemption Price of, and (unless the Redemption Date shall be an Interest
Payment Date) interest accrued to the Redemption Date on, all Securities or
portions thereof which are to be redeemed on that date.

                                      -83-
<PAGE>   92
                  Unless any Security by its terms prohibits any redemption
obligation from being satisfied by delivering and crediting Securities
(including Securities redeemed otherwise than through a sinking fund), the
Company may deliver such Securities to the Trustee for crediting of an amount
equal to the then applicable Redemption Price for such Securities against such
payment obligation in accordance with the terms of such Securities and this
Indenture.

                  Section 11.6. Securities Payable on Redemption Date. Notice of
redemption having been given as aforesaid, the Securities so to be redeemed
shall, on the Redemption Date, become due and payable at the Redemption Price
therein specified, and from and after such date (unless the Company shall
default in the payment of the Redemption Price and accrued interest) such
Securities shall cease to bear interest and the interest coupons for any such
interest appertaining to any Bearer Security so to be redeemed, except to the
extent provided below, shall be void. Except as provided in the next succeeding
paragraph, upon surrender of any such Security, including interest coupons, if
any, for redemption in accordance with said notice, such Security shall be paid
by the Company at the Redemption Price, together with accrued interest to the
Redemption Date; provided, however, that installments of interest on Bearer
Securities whose Stated Maturity is on or prior to the Redemption Date shall be
payable only at an office or agency located outside the United States and its
possessions (except as otherwise provided in Section 9.2) and, unless otherwise
specified as contemplated by Section 3.1, only upon presentation and surrender
of interest coupons for such interest; and provided, further, that, unless
otherwise specified as contemplated by Section 3.1, installments of interest on
Registered Securities that are due and payable on Interest Payment Dates that
are on or prior to the Redemption Date shall be payable to the Holders of such
Securities, or one or more Predecessor Securities, registered as such at the
close of business on the relevant Regular Record Dates according to their terms
and the provisions of Section 3.7.

                  If any Bearer Security surrendered for redemption shall not be
accompanied by all appurtenant interest coupons maturing after the Redemption
Date, such Bearer Security may be paid after deducting from the Redemption Price
an amount equal to the face amount of all such missing interest coupons, or the
surrender of such missing interest coupon or interest coupons may be waived by
the Company and the Trustee if there be furnished to them such security or
indemnity as they may require to save each of them and any Paying Agent
harmless. If thereafter the Holder of such Bearer Security shall surrender to
the Trustee or any Paying Agent any such missing interest coupon in respect of
which a deduction shall have been made from the Redemption Price, such Holder
shall be entitled to receive the amount so deducted; provided, however, that
interest represented by interest coupons shall be payable only at an office or
agency located outside of the United States (except as otherwise provided
pursuant to Section 9.2) and, unless otherwise specified as contemplated by
Section 3.1, only upon presentation and surrender of those interest coupons.

<PAGE>   93
                  If any Security called for redemption shall not be so paid
upon surrender thereof for redemption, the principal (and premium, if any)
shall, until paid, bear interest from the Redemption Date at the rate prescribed
therefor in the Security.

                  Section 11.7. Securities Redeemed in Part. Upon surrender of a
Security that is redeemed in part at any Place of Payment therefor (with, if the
Company or the Trustee so required, 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 or her attorney duly authorized in writing), the
Company shall execute and the Trustee shall authenticate and deliver to the
Holder of that Security, without service charge, a new Security or Securities
(each with a Senior Subordinated Guarantee of each Guarantor executed by each
such Guarantor and endorsed thereon) of the same series, having the same form,
terms and Stated Maturity, in any authorized denomination equal in aggregate
principal amount to the unredeemed portion of the principal amount of the
Security surrendered.

                                  SINKING FUNDS

                  Section 12.1. Applicability of Article. The provisions of this
Article shall be applicable to any sinking fund for the retirement of Securities
of a series except as otherwise specified as contemplated by Section 3.1 for
Securities of such series.

                  The minimum amount of any sinking fund payment provided for by
the terms of Securities of any series is herein referred to as a "mandatory
sinking fund payment," and any payment in excess of such minimum amount provided
for by the terms of Securities of any series is herein referred to as an
"optional sinking fund payment." If provided for by the terms of Securities of
any series, the cash amount of any sinking fund payment may be subject to
reduction as provided in Section 12.2. Each sinking fund payment shall be
applied to the redemption of Securities of any series as provided for by the
terms of Securities of such series.

                  Section 12.2. Satisfaction of Sinking Fund Payments with
Securities. The Company (i) may deliver Outstanding Securities of a series
(other than any previously called for redemption) together, in the case of
Bearer Securities of such series, with all unmatured interest coupons
appertaining thereto and (ii) may apply as a credit Securities of a series which
have been (x) redeemed either at the election of the Company pursuant to the
terms of such Securities or through the application of permitted optional
sinking fund payments pursuant to the terms of such Securities, (y) converted or
exchanged pursuant to Article 14 or (z) previously delivered to the Trustee and
cancelled without reissuance pursuant to Section 3.9, in each case in
satisfaction of all or any part of any

                                      -85-
<PAGE>   94
sinking fund payment with respect to the Securities of such series required to
be made pursuant to the terms of such Securities as provided for by the terms of
such series; provided that such Securities have not been previously so credited.
Such Securities shall be received and credited for such purpose by the Trustee
at the Redemption Price specified in such Securities for redemption through
operation of the sinking fund and the amount of such sinking fund payment shall
be reduced accordingly.

                  Section 12.3. Redemption of Securities for Sinking Fund. Not
less than 45 days prior to each sinking fund payment date for any series of
Securities, the Company will deliver to the Trustee an Officers' Certificate
specifying the amount of the next ensuing sinking fund payment for that series
pursuant to the terms of that series, the portion thereof, if any, which is to
be satisfied by payment of cash and the portion thereof, if any, which is to be
satisfied by delivering and crediting Securities of that series pursuant to
Section 12.2 and stating the basis for such credit and that such Securities have
not been previously so credited, and will also deliver to the Trustee any
Securities to be so delivered. Not less than 30 days before each such sinking
fund payment date the Trustee shall select the Securities to be redeemed upon
such sinking fund payment date in the manner specified in Section 11.3 and cause
notice of the redemption thereof to be given in the name of and at the expense
of the Company in the manner provided in Section 11.4. Such notice having been
duly given, the redemption of such Securities shall be made upon the terms and
in the manner stated in Sections 11.6 and 11.7.

<PAGE>   95
                  (b) In case at any time the Company, pursuant to a Board
Resolution, or the Holders of at least 33 1/3% in principal amount of the
Outstanding Securities of any series shall have requested the Trustee to call a
meeting of the Holders of Securities of such series for any purpose specified in
Section 13.1, by written request setting forth in reasonable detail the action
proposed to be taken at the meeting, and the Trustee shall not have made the
first publication of the notice of such meeting within 21 days after receipt of
such request or shall not thereafter proceed to cause the meeting to be held as
provided herein, then the Company or the Holders of Securities of such series in
the amount specified, as the case may be, may determine the time and the place
in The City of New York or such other place as may be acceptable to the Company
for such meeting and may call such meeting for such purposes by giving notice
thereof as provided in paragraph (a) of this Section.

                  Section 13.3. Persons Entitled to Vote at Meetings. To be
entitled to vote at any meeting of Holders of Securities of any series issuable
as Bearer Securities, a Person shall be (a) a Holder of one or more Outstanding
Securities of such series, or (b) a Person appointed by an instrument in writing
as proxy for a Holder or Holders of one or more Outstanding Securities of such
series by such Holder or Holders. The only Persons who shall be entitled to be
present or to speak at any meeting of Holders shall be the Persons entitled to
vote at such meeting and their counsel, any representatives of the Trustee and
its counsel and any representatives of the Company and its counsel.

                  Section 13.4. Quorum; Action. The Persons entitled to vote a
majority in principal amount of the Outstanding Securities of the applicable
series shall constitute a quorum. In the absence of a quorum within 30 minutes
of the time appointed for any such meeting, the meeting shall, if convened at
the request of Holders of Securities of such series, be dissolved. In any other
case the meeting may be adjourned for a period of not less than 10 days as
determined by the chairman of the meeting prior to the adjournment of such
meeting. In the absence of a quorum at any such adjourned meeting, such
adjourned meeting may be further adjourned for a period not less than 10 days as
determined by the chairman of the meeting prior to the adjournment of such
adjourned meeting. Notice of the reconvening of any such adjourned meeting shall
be given as provided in Section 13.2(a), except that such notice need be given
only once not less than five days prior to the date on which the meeting is
scheduled to be reconvened.

                  At the reconvening of any meeting adjourned for a lack of a
quorum pursuant to the preceding paragraph, the Persons entitled to vote 25% in
principal amount of the Outstanding Securities of the applicable series at the
time shall constitute a quorum for the taking of any action set forth in the
notice of the original meeting. Notice of the reconvening of a meeting adjourned
for lack of a quorum shall state expressly the percentage of the principal
amount of the Outstanding Securities of such series which shall constitute a
quorum.

                                      -87-
<PAGE>   96
                  At a meeting or an adjourned meeting duly reconvened and at
which a quorum is present as aforesaid, any resolution and all matters (except
as limited by the proviso to Section 8.2) shall be effectively passed and
decided if passed or decided by the Persons entitled to vote not less than the
lesser of (i) a majority in principal amount of Outstanding Securities of the
applicable series and (ii) 66 2/3% in principal amount of Outstanding Securities
of such series represented and voting at such meeting; provided, however, that
any resolution with respect to any request, demand, authorization, direction,
notice, consent, election, waiver or other Act which this Indenture expressly
provides may be made, given or taken by the Holders of a specified percentage,
which is less than a majority, in principal amount of the Outstanding Securities
of a series may be adopted at a meeting or an adjourned meeting duly reconvened
and at which a quorum is present as aforesaid by the affirmative vote of the
lesser of (i) the Holders of such specified percentage in principal amount of
the Outstanding Securities of such series and (ii) a majority in principal

                  Any resolution passed or decisions taken at any meeting of
Holders of Securities of any series issuable as Bearer Securities duly held in
accordance with this Section shall be binding on all the Holders of Securities
of such series and interest coupons, whether or not present or represented at
the meeting.

                  In the event that any meeting shall be adjourned for lack of a
quorum or that, at any meeting at which a quorum is present, any proposed
resolution or decision shall not be passed or taken because the Holders of the
percentage of Outstanding Securities of any series issuable as Bearer Securities
needed to approve such resolution or decision did not vote in favor of such
resolution or decision, the principal amount of Outstanding Securities of such
series represented at such meeting and voting in favor of such resolution or
decision may be counted for purposes of calculating whether the consent of the
Holders of the percentage of Outstanding Securities of such series needed in
order to make, give or take any request, demand, authorization, direction,
notice, consent, election, waiver or other action has been obtained, and such
vote shall constitute the consent thereto of such Holders.

                  Section 13.5. Determination of Voting Rights; Conduct and
Adjournment of Meetings. (a) Notwithstanding any other provisions of this
Indenture, the Trustee may make such reasonable regulations as it may deem
advisable for any meeting of Holders of Securities of any series issuable as
Bearer Securities in regard to proof of the holding of Securities of such series
and of the appointment of proxies and in regard to the appointment and duties of
inspectors of votes, the submission and examination of proxies, certificates and
other evidence of the right to vote, and such other matters concerning the
conduct of the meeting as it shall deem appropriate. Except as otherwise
permitted or required by any such regulations, the holding of Securities of a
series issuable as Bearer

                                      -88-
<PAGE>   97
Securities shall be proved in the manner specified in Section 1.4 and the
appointment of any proxy shall be provided in the manner specified in Section
1.4 or by having the signature of the Person executing the proxy witnessed or
guaranteed by any trust company, bank or banker authorized by Section 1.4 to
certify to the holding of Bearer Securities. Such regulations may provide that
written instruments appointing proxies, regular on their face, may be presumed
valid and genuine without the proof specified in Section 1.4 or other proof.

                  (b) The Trustee shall, by an instrument in writing, appoint a
temporary chairman (which may be a Responsible Officer of the Trustee) of the
meeting, unless the meeting shall have been called by the Company or by Holders
of Securities of a series as provided in Section 13.2(b), in which case the
Company or the Holders of Securities of such series calling the meeting, as the
case may be, shall in like manner appoint a temporary chairman. A permanent
chairman and a permanent secretary of the meeting shall be elected by vote of
the Persons entitled to vote a majority in principal amount of the Outstanding
Securities of such series represented at the meeting.

                  (c) At any meeting each Holder of a Security or proxy shall be
entitled to one vote for each U.S. $5,000 principal amount of Securities held or
represented by him or her; provided, however, that no vote shall be cast or
counted at any meeting in respect of any Security challenged as not Outstanding
and ruled by the chairman of the meeting to be not Outstanding. The chairman of
the meeting shall have no right to vote, except as a Holder of a Security or
proxy.

                  (d) Any meeting of Holders of Securities of a series issuable
as Bearer Securities duly called pursuant to Section 13.2 at which a quorum is
present may be adjourned from time to time by Persons entitled to vote a
majority in principal amount of the Outstanding Securities of such series
represented at the meeting, and the meeting may be held as so adjourned without
further notice.

                  Section 13.6. Counting Votes and Recording Action of Meetings.
The vote upon any resolution submitted to any meeting of Holders of Securities
of any series issuable as Bearer Securities shall be by written ballots on which
shall be subscribed the signatures of the Holders of Securities of such series
or of their representatives by proxy and the principal amounts and serial
numbers of the Outstanding Securities held or represented by them. The permanent
chairman of the meeting shall appoint an inspector of votes who shall count all
votes cast at the meeting for or against any resolution and who shall make and
file with the secretary of the meeting its verified written report of all votes
cast at the meeting. A record of the proceedings of each meeting of Holders of
Securities shall be prepared by the applicable secretary of the meeting and
there shall be attached to said record the original report of the inspector of
votes on any vote by ballot taken thereat and affidavits by one or more Persons
having knowledge of the facts setting

                                      -89-
<PAGE>   98
forth a copy of the notice of the meeting and showing that said notice was given
as provided in Section 13.2 and, if applicable, Section 13.4. At least two
copies of such record shall be signed and verified by the affidavits of the
permanent chairman and secretary of the meeting and one copy thereof shall be
delivered to the Company and the other to the Trustee to be preserved by the
Trustee, the latter to have attached thereto the ballots voted at the meeting.
Any record so signed and verified shall be conclusive evidence of the matters
therein stated.

this Article 14 shall be applicable to the Securities of any series which are
convertible or exchangeable into Equity Securities of Allied, and to the
issuance of such Equity Securities upon the conversion or exchange of such
Securities, except as otherwise specified as contemplated by Section 3.1 for the
Securities of such series.

                  (b) For purposes of this Article 14, the term "Equity

                  Section 14.2. Exercise of Conversion or Exchange Privilege.
(a) In order to exercise a conversion or exchange privilege, the Holder of a

coupons and any matured interest coupons in default appertaining thereto, to the
Company at the office or agency maintained for that purpose pursuant to Section
9.2, accompanied by written notice to Allied and the Company that the Holder
elects to convert or exchange such Security or a specified portion thereof. Such
notice shall also state, if different from the name and address of such Holder,
the name or names (with address) in which the certificate or certificates for
Equity Securities which shall be issuable on such conversion or exchange shall
be issued. Registered Securities surrendered for conversion or exchange shall
(if so required by Allied, the Company or the Trustee) be duly endorsed by or
accompanied by instruments of transfer in forms satisfactory to Allied, the
Company and the Trustee duly executed by the registered Holder or its attorney
duly authorized in writing.

                  (b) Registered Securities so surrendered for conversion or
exchange during the period from the close of business on any Regular Record Date
to the opening of business on the corresponding Interest Payment Date (excluding
Securities or portions thereof called for redemption during such period) shall
also be accompanied by payment

                                      -90-

in funds acceptable to the Company of an amount equal to the interest payable on
such Interest Payment Date on the principal amount of such Security then being
converted or exchanged, and such interest shall be payable to such registered
Holder on such Interest Payment Date notwithstanding the conversion or exchange
of such Security, subject to the provisions of Section 3.7 relating to the
payment of Defaulted Interest by the Company.

                  (c) As promptly as practicable after the receipt of such
notice and of any payment required pursuant to a Board Resolution and, subject
to Section 3.3, set forth, or determined in the manner provided, in an Officers'
Certificate, or established in one or more indentures supplemental hereto
setting forth the terms of such series of Security, and the surrender of such
Security in accordance with such reasonable regulations as Allied and the
Company may prescribe, Allied shall issue and shall deliver, at the office or
agency at which such Security is surrendered, to such Holder or on its written
order, a certificate or certificates for the number of Equity Securities
issuable upon the conversion or exchange of such Security (or specified portion
thereof), in accordance with the provisions of such Board Resolution, Officers'
Certificate or supplemental indenture, and cash as provided therein in respect
of any fractional share of such Equity Security otherwise issuable upon such
conversion or exchange.

                  (d) Such conversion or exchange shall be deemed to have been
effected immediately prior to the close of business on the date on which such
notice and such payment, if required, shall have been received in proper order
for conversion or exchange by Allied and the Company and such Security shall
have been surrendered as aforesaid and at such time the rights of the Holder of
such Security as such Security Holder shall cease and the person or persons in
whose name or names any certificate or certificates for Equity Securities of
Allied shall be issuable upon such conversion or exchange shall be deemed to
have become the Holder or Holders of record of the Equity Securities represented
thereby. Except as set forth above and subject to paragraph (d) of Section 3.7,
no payment or adjustment shall be made upon any conversion or exchange on
account of any interest accrued on the Securities surrendered for conversion or
exchange, or on account of any dividends on the Equity Securities of Allied
issued upon such conversion or exchange if the record date for the payment of
such dividends occurs prior to or on the date on which such conversion or
exchange shall be deemed to have been effected.

                  In the case of any Security which is converted or exchanged in
part only, upon such conversion or exchange the Company shall execute and the
Trustee shall authenticate and deliver to or on the order of the Holder thereof,
at the expense of the Company, a new Security or Securities of the same series,
of authorized denominations, in aggregate principal amount equal to the
unconverted or unexchanged portion of such Security.

                  Section 14.3. No Fractional Equity Securities. No fractional
Equity Security of Allied shall be issued upon conversions or exchanges of
Securities of any series. If more than one Security shall be surrendered for
conversion or exchange at one time by the same Holder, the number of full shares
of the Equity Security which shall be issuable upon conversion or exchange shall
be computed on the basis of the aggregate principal amount of the Securities (or
specified portions thereof to the extent permitted hereby) so surrendered. If,
except for the provisions of this Section 14.3, any Holder of a Security or
Securities would be entitled to a fractional share of any Equity Security of
Allied upon the conversion or exchange of such Security or Securities, or
specified portions thereof, Allied or the Company shall pay to such Holder an
amount in cash equal to the current market value of such fractional share
computed, (i) if such Equity Security is listed or admitted to unlisted trading
privileges on a national securities exchange, on the basis of the last reported
sale price regular way on the principal exchange where such Equity Security is
listed or admitted, on the last trading day prior to the date of conversion or
exchange upon which such a sale shall have been effected, (ii) if such Equity
Security is not at the time so listed or admitted on a national securities
exchange but is quoted on the National Market System of the National Association
of Securities Dealers, Inc. ("NASDAQ"), on the basis of the average of the bid
and asked prices of such Equity Security on NASDAQ on the last trading day prior
to the date of conversion or exchange, (iii) if such Equity Security is not at
the time so listed or admitted to unlisted trading privileges on a national
securities exchange or quoted on NASDAQ, on the basis of the average of the bid
and asked prices of such Equity Security in the over-the-counter market, on the
last trading day prior to the date of conversion or exchange, as reported by the
National Quotation Bureau Incorporated or similar organization if the National
Quotation Bureau Incorporated is no longer reporting such information, or (iv)
in accordance with the terms of the supplemental indenture or Board Resolutions
setting the terms of the Securities of such series. For purposes of this
Section, "trading day" shall mean each Monday, Tuesday, Wednesday, Thursday and
Friday other than any day on which the applicable Equity Security is not traded
or quoted on a national securities exchange, or if the applicable Equity
Security is not traded or quoted on a national securities exchange, on NASDAQ or
the principal exchange or market on which the applicable Equity Security is
traded or quoted.

                  Section 14.4. Adjustment of Conversion or Exchange Price;
Consolidation or Merger. The conversion or exchange price of Securities of any
series that is convertible or exchangeable into an Equity Security of Allied
shall be adjusted for any stock dividends, stock splits, reclassification,
combinations or similar transactions, and the securities, assets or other
property into or for which such Securities may be converted or exchanged as a
result of any consolidation, merger, combination or similar transaction shall be
determined, in accordance with the terms of the supplemental indenture or Board
Resolutions setting the terms of the Securities of such series.

                  Whenever the conversion or exchange price is adjusted, Allied
and the Company shall compute the adjusted conversion or exchange price in
accordance with the terms of the applicable Board Resolution or supplemental
indenture and shall prepare an Officers' Certificate setting forth the adjusted
conversion or exchange price and showing in reasonable detail the facts upon
which such adjustment is based. Whenever the securities, assets or other
property into or for which Securities of any series may be converted or
exchanged are changed as a result of any consolidation, merger or similar
transaction, Allied and the Company shall determine the nature and amount of
such securities, assets or other property in accordance with the terms of the
applicable Board Resolution or supplemental indenture and shall prepare an
Officer's Certificate describing such securities, assets or other property and
stating the amount of such securities, assets or other property into or for
which such Securities have become convertible or exchangeable. Such certificates
shall forthwith be filed at each office or agency maintained for the purpose of
conversion or exchange of Securities pursuant to Section 9.2 and, if different,
with the Trustee. Allied and the Company shall forthwith cause a notice setting
forth the adjusted conversion or exchange price or describing such securities,
assets or other property, as applicable, to be mailed, first class postage
prepaid, to each Holder of Registered Securities of such series at its address
appearing on the Register and to any conversion or exchange agent other than the
Trustee.

                  Section 14.5. Notice of Certain Corporate Actions. If any
series of Securities which are directly or indirectly convertible or
exchangeable for any Equity Securities are Outstanding, in case:

                  (a) Allied shall declare a dividend (or any other
         distribution) on any class of such Equity Securities payable otherwise
         than in cash out of its retained earnings (other than a dividend for
         which approval of any stockholder of Allied is required); or

                  (b) Allied shall authorize the granting to the holders of any
         class of such Equity Securities of rights, options or warrants to
         subscribe for or purchase any shares of capital stock of any class or
         of any other rights (other than any such grant for which approval of
         any stockholder of Allied is required); or

                  (c) of any reclassification of any class of such Equity
         Securities (other than a subdivision or combination of its outstanding
         Equity Securities, or of any consolidation, merger or share exchange to
         which Allied is a party and for which approval of any stockholder of
         Allied is required), or of the sale of all or substantially all of the
         assets of Allied; or

                  (d) of the voluntary or involuntary dissolution, liquidation
         or winding up of Allied;

                                      -93-
<PAGE>   102
then Allied and the Company shall cause to be filed with the Trustee, and shall
cause to be mailed to all Holders at their addresses as they shall appear in the
Register, at least 15 days (or 10 days in any case specified in clause (a) or
(b) above) prior to the applicable record date hereinafter specified, a notice
stating (i) the date on which a record is to be taken for the purpose of such
dividend, distribution, rights, options or warrants, or, if a record is not to
be taken, the date as of which the Holders of such Equity Securities of record
to be entitled to such dividend, distribution, rights, options or warrants are
to be determined, or (ii) the date on which such reclassification,
consolidation, merger, share exchange, sale, dissolution, liquidation or winding
up is expected to become effective, and the date as of which it is expected that
holders of such Equity Securities of record shall be entitled to exchange such
Equity Securities for securities, cash or other property deliverable upon such
reclassification, consolidation, merger, share exchange, sale, dissolution,
liquidation or winding up. If at any time the Trustee shall not be the
conversion or exchange agent, a copy of such notice shall also forthwith be
filed by Allied and the Company with the Trustee.

                  Section 14.6. Reservation of Equity Securities. Allied shall
at all times reserve and keep available, free from preemptive rights, out of its
authorized but unissued Equity Securities, for the purpose of effecting the
conversion or exchange of Securities, the full number of Equity Securities of
Allied then issuable upon the conversion or exchange of all Outstanding
Securities of any series that has conversion or exchange rights.

                  Section 14.7. Payment of Certain Taxes Upon Conversion or
Exchange. Allied and the Company will pay any and all taxes that may be payable
in respect of the issue or delivery of Allied's Equity Securities on conversion
or exchange of Securities pursuant hereto. Allied and the Company shall not,
however, be required to pay any tax which may be payable in respect of any
transfer involved in the issue and delivery of its Equity Securities in a name
other than that of the Holder of the Security or Securities to be converted or
exchanged, and no such issue or delivery shall be made unless and until the
Person requesting such issue has paid to Allied and the Company the amount of
any such tax, or has established, to the satisfaction of Allied and the Company,
that such tax has been paid.

                  Section 14.8. Duties of Trustee Regarding Conversion or
Exchange. Neither the Trustee nor any conversion or exchange agent shall at any
time be under any duty or responsibility to any Holder of Securities of any
series that is convertible or exchangeable into Equity Securities of Allied to
determine whether any facts exist which may require any adjustment of the
conversion or exchange price, or with respect to the nature or extent of any
such adjustment when made, or with respect to the method employed, whether
herein or in any supplemental indenture, any resolutions of the Board of
Directors or written instrument executed by one or more officers of Allied and
the

                                      -94-

Company provided to be employed in making the same. Neither the Trustee nor any
conversion or exchange agent shall be accountable with respect to the validity
or value (or the kind or amount) of any Equity Securities of Allied, or of any
securities or property, which may at any time be issued or delivered upon the
conversion or exchange of any Securities and neither the Trustee nor any
conversion or exchange agent makes any representation with respect thereto.
Subject to the provisions of Section 6.1, neither the Trustee nor any conversion
or exchange agent shall be responsible for any failure of Allied or the Company
to issue, transfer or deliver any of its Equity Securities or stock certificates
or other securities or property upon the surrender of any Security for the
purpose of conversion or exchange or to comply with any of the covenants of
Allied and the Company contained in this Article 14 or in the applicable
supplemental indenture, resolutions of the Board of Directors or written
instrument executed by one or more duly authorized officers of Allied and the
Company.

shall after such conversion or exchange be repaid to the Company by the Trustee
upon the Company's written request by Company Request.

         SUBORDINATION OF SECURITIES AND SENIOR SUBORDINATED GUARANTEES

                  Section 15.1. Securities Subordinate to Senior Debt. The
Company covenants and agrees, and each Holder of a Security, by his acceptance
thereof, likewise covenants and agrees, that, to the extent and in the manner
hereinafter set forth in this Article (subject to the provisions of Article 4),
(i) the payment of the principal of (and premium, if any) and interest on the
Securities and any other obligations in respect of the Securities (including any
obligation to repurchase Securities) are hereby expressly made subordinate and
subject in right of payment to the prior payment in full of all Senior Debt of
the Company, and (ii) the payment of each Guarantor's obligations in respect of
its Senior Subordinated Guarantee is hereby expressly made subordinate and
subject in right of payment to the prior payment in full of all the obligations
of such Guarantor under all Senior Debt of such Guarantor.

                  Section 15.2. Payment Over of Proceeds Upon Dissolution, Etc.
In the event of (a) any insolvency or bankruptcy case or proceeding, or any
receivership, liquidation, reorganization or other similar case or proceeding in
connection therewith,

relative to the Company or to its creditors, as such, or to its assets, or (b)
any liquidation, dissolution or other winding up of the Company, whether
voluntary or involuntary and whether or not involving insolvency or bankruptcy,
or (c) any assignment for the benefit of creditors or any other marshaling of
assets and liabilities of the Company, then and in any such event specified in
(a), (b) or (c) above (each such event, if any, herein sometimes referred to as
a "Company Proceeding") the holders of all Senior Debt of the Company shall
first be entitled to receive payment in full of all amounts due or to become due
on or in respect of all such Senior Debt, or provision shall be made for such
payment in cash or cash equivalents or otherwise in a manner satisfactory to the
holders of such Senior Debt, before the Holders of the Securities are entitled
to receive any payment or distribution of any kind or character from the
Company, whether in cash, property or securities (including any payment or
distribution which may be payable or deliverable by reason of the payment of any
other Debt of the Company subordinated to the payment of the Securities on
account of principal of (or premium, if any) or interest on or other obligations
in respect of the Securities or on account of any purchase or other acquisition
of Securities by the Company or Allied or any Subsidiary of the Company (all
such payments, distributions, purchases and acquisitions herein referred to,
individually and collectively, as a "Company Securities Payment"), and to that
end the holders of Senior Debt of the Company shall be entitled to receive, for
application to the payment thereof, any Company Securities Payment which may be
payable or deliverable in respect of the Securities in any such Company
Proceeding.

                  In the event of (a) any insolvency or bankruptcy case or
proceeding, or any receivership, liquidation, reorganization or other similar
case or proceeding in connection therewith, relative to any Guarantor or to its
creditors, as such, or to its assets, or (b) any liquidation, dissolution or
other winding up of any Guarantor, whether voluntary or involuntary and whether
or not involving insolvency or bankruptcy, or (c) any assignment for the benefit
of creditors or any other marshaling of assets and liabilities of any Guarantor,
then and in any such event specified in (a), (b) or (c) above (each such event,
if any, herein sometimes referred to as a "Guarantor Proceeding"; the Company
Proceeding and the Guarantor Proceeding each may be referred to as a
"Proceeding") the holders of all Senior Debt of such Guarantor shall first be
entitled to receive payment in full of all amounts due or to become due on or in
respect of all such Senior Debt, or provision shall be made for such payment in
cash or cash equivalents or otherwise in a manner satisfactory to the holders of
such Senior Debt, before the Holders of the Securities are entitled to receive
any payment or distribution of any kind or character from such Guarantor,
whether in cash, property or securities (including any payment or distribution
which may be payable or deliverable by reason of the payment of any other Debt
of such Guarantor subordinated to the payment of its Senior Subordinated
Guarantee by such Guarantor) on account of its Senior Subordinated Guarantee
(all such payments and distributions herein referred to, individually and
collectively, as a "Guarantor

Securities Payment"; any of the Company Securities Payment and the Guarantor
Securities Payment each may be referred to as a "Securities Payment"), and to
that end the holders of Senior Debt of such Guarantor shall be entitled to
receive, for application to the payment thereof, any Guarantor Securities
Payment which may be payable or deliverable in respect of the Senior
Subordinated Guarantee by such Guarantor in any such Guarantor Proceeding.

                  In the event that, notwithstanding the foregoing provisions of
this Section, the Trustee or the Holder of any Security shall have received any
Securities Payment before all Senior Debt the Company or the Guarantor, as
applicable, is paid in full or payment thereof provided for in cash or cash
equivalents or otherwise in a manner satisfactory to the holders of such Senior
Debt, then and in such event such Securities Payment shall be paid over or
delivered forthwith to the holders of Senior Debt for application to the payment
of such Senior Debt remaining unpaid, to the extent necessary to pay such Senior
Debt in full, after giving effect to any concurrent payment or distribution to
or for the holders of such Senior Debt.

                  The consolidation of the Company or any Guarantor with, or the
merger of the Company or any Guarantor into, another Person or the liquidation
or dissolution of the Company or any Guarantor following the conveyance or
transfer of all or substantially all of its properties and assets as an entirety
to another Person upon the terms and conditions set forth in Article 7 shall not
be deemed a Proceeding for the purposes of this Section if the Person formed by
such consolidation or into which the Company or any Guarantor is merged or the
Person which acquires by conveyance or transfer such properties and assets as an
entirety, as the case may be, shall, as a part of such consolidation, merger,
conveyance or transfer, comply with the conditions set forth in Article 7.

                  Section 15.3. No Payment When Senior Debt in Default. In the
event that any Company Senior Payment Default (as defined below) shall have
occurred and be continuing, then no Company Securities Payment shall be made
unless and until such Company Senior Payment Default shall have been cured or
waived or shall have ceased to exist or all amounts then due and payable in
respect of Senior Debt of the Company shall have been paid in full, or provision
shall have been made for such payment in cash or otherwise in a manner
satisfactory to the holders of such Senior Debt. "Company Senior Payment
Default" means (i) any default in the payment of principal of (or premium, if
any) or interest on any Senior Debt of the Company and (ii) any event of default
with respect to Senior Debt of the Company which has resulted in such Senior
Debt becoming or being declared due and payable prior to the date on which it
would otherwise have become due and payable.

                  In the event that any Guarantor Senior Payment Default (as
defined below) with respect to any Guarantor shall have occurred and be
continuing, then no Guarantor Securities Payment shall be made by such Guarantor
unless and until such Guarantor Senior Payment Default shall have been cured or
waived or shall have ceased to exist or all amounts then due and payable in
respect of the Senior Debt of such Guarantor shall have been paid in full, or
provision shall have been made for such payment in cash or otherwise in a manner
satisfactory to the holders of Senior Debt of such Guarantor. "Guarantor Senior
Payment Default" means, with respect to any Guarantor, (i) any default in the
payment of principal of (or premium, if any) or interest on any Senior Debt of
such Guarantor and (ii) any event of default with respect to Senior Debt of such
Guarantor which has resulted in such Senior Debt becoming or being declared due
and payable prior to the date on which it would otherwise have become due and
payable. Any Company Senior Payment Default or Guarantor Senior Payment Default
may be referred to herein as a "Senior Payment Default".

                  In the event that any Company Senior Nonmonetary Default (as
defined below) shall have occurred and be continuing, then, upon the receipt by
the Company and the Trustee of written notice of such Company Senior Nonmonetary
Default from the Agent Banks under the Credit Agreement (or if such Credit
Agreement has been terminated, from any holder of Senior Debt of the Company
with a principal amount in excess of $50,000,000), no Company Securities Payment
shall be made during the period (the "Company Payment Blockage Period")
commencing on the date of such receipt of such written notice and ending on the
earlier of (i) the date on which such Company Senior Nonmonetary Default shall
have been cured or waived or shall have ceased to exist and any acceleration of
Senior Debt of the Company shall have been rescinded or annulled or the Senior
Debt of the Company to which such Company Senior Nonmonetary Default relates
shall have been discharged or (ii) the 179th day after the date of such receipt
of such written notice. No more than one Company Payment Blockage Period may be
commenced with respect to the Securities during any consecutive 360-day period.
For all purposes of this paragraph, no Senior Nonmonetary Default that existed
or was continuing on the date of commencement of any Company Payment Blockage
Period shall be, or be made, the basis for the commencement of a subsequent
Company Payment Blockage Period whether or not within a period of 360
consecutive days by holders of Senior Debt of the Company or their
representatives unless such Company Senior Nonmonetary Default shall have been
cured for a period of not less than 90 consecutive days. "Company Senior
Nonmonetary Default" means the occurrence or existence and continuance of any
event of default, or of any event which, after notice or lapse of time (or
both), would become an event of default, under the terms of any instrument
pursuant to which any Senior Debt of the Company is outstanding, permitting
(after notice or lapse of time or both) one or more holders of such Senior Debt
(or a trustee or agent on behalf of the holders thereof) to declare such Senior
Debt due

                                      -98-
<PAGE>   107
and payable prior to the date on which it would otherwise become due and
payable, other than a Company Senior Payment Default.

                  In the event that a Guarantor Senior Nonmonetary Default (as
defined below) with respect to any Guarantor shall have occurred and be
continuing, then, upon the receipt by such Guarantor and the Trustee of written
notice of such Guarantor Senior Nonmonetary Default from a holder of Senior Debt
of such Guarantor with a principal amount in excess of $50 million, no Guarantor
Securities Payment shall be made by such Guarantor during the period (a
"Guarantor Payment Blockage Period") commencing on the date of such receipt of
such written notice and ending on the earlier of (i) the date on which such
Guarantor Senior Nonmonetary Default shall have been cured or waived or shall
have ceased to exist and any acceleration of Senior Debt of such Guarantor shall
have been rescinded or annulled or the Senior Debt of such Guarantor to which
such Guarantor Senior Nonmonetary Default relates shall have been discharged or
(ii) the 179th day after the date of such receipt of such written notice. No
more than one Guarantor Payment Blockage Period may be commenced with respect to
the Securities during any 360-day period. For all purposes of this paragraph, no
Guarantor Senior Nonmonetary Default with respect to a Guarantor that existed or
was continuing on the date of commencement of any Guarantor Payment Blockage
Period with respect to such Guarantor shall be, or be made, the basis for the
commencement of a subsequent Guarantor Payment Blockage Period with respect to
such Guarantor whether or not within a period of 360 consecutive days by holders
of Senior Debt of such Guarantor or their representatives unless such Guarantor
Senior Nonmonetary Default shall have been cured for a period of not less than
90 consecutive days. A "Guarantor Senior Nonmonetary Default" means, with
respect to any Guarantor, the occurrence or existence and continuance of any
event of default, or of any event which, after notice or lapse of time (or
both), would become an event of default, under the terms of any instrument
pursuant to which any Senior Debt of such Guarantor is outstanding, permitting
(after notice or lapse of time or both) one or more holders of such Senior Debt
(or a trustee or agent on behalf of the holders thereof) to declare such Senior
Debt due and payable prior to the date on which it would otherwise become due
and payable, other than a Guarantor Senior Payment Default. Any of the Company
Senior Nonmonetary Default and the Guarantor Senior Nonmonetary Defaults may be
referred to herein as a "Senior Nonmonetary Default".

                  In the event that, notwithstanding the foregoing, the Company
or any Guarantor shall make any Company Securities Payment or Guarantor
Securities Payment, as the case may be, to the Trustee or any Holder prohibited
by the foregoing provisions of this Section, then and in such event such
Securities Payment shall be paid over and delivered forthwith to the holders of
the Senior Debt of the Company or the Guarantor, as the case may be.

                  The provisions of this Section shall not apply to any
Securities Payment with respect to which Section 15.2 would be applicable.

                  Section 15.4. Certain Payments Permitted. Nothing contained in
this Article or elsewhere in this Indenture or in any of the Securities or the
Senior Subordinated Guarantees endorsed thereon shall prevent the Company or any
Guarantor, at any time except during the pendency of any Proceeding referred to
in Section 15.2 or under the conditions described in Section 15.3, from making
Securities Payments.

                  Section 15.5. Subrogation to Rights of Holders of Senior Debt.
Subject to the payment in full in cash of all amounts due or to become due on or
in respect of Senior Debt of the Company or a Guarantor, as the case may be, or
the provision for such payment in cash or cash equivalents or otherwise in a
manner satisfactory to the holders of such Senior Debt, the Holders of the
Securities shall be subrogated to the rights of the holders of such Senior Debt
to receive payments and distributions of cash, property and securities
applicable to such Senior Debt until the principal of (and premium, if any) and
interest on the Securities or the obligation under such Guarantor's Senior
Subordinated Guarantee, as the case may be, shall be paid in full. For purposes
of such subrogation, no payments or distributions to the holders of the Senior
Debt of the Company or a Guarantor of any cash, property or securities to which
the Holders of the Securities or the Trustee would be entitled except for the
provisions of this Article, and no payments over pursuant to the provisions of
this Article to the holders of Senior Debt of the Company or such Guarantor, as
the case may be, by Holders of the Securities or the Trustee, shall, as among
the Company or such Guarantor, as the case may be, its creditors other than
holders of Senior Debt and the Holders of the Securities, be deemed to be a
payment or distribution by the Company or such Guarantor, as applicable, to or
on account of the Senior Debt of the Company or such Guarantor, as the case may
be.

                  Section 15.6. Provisions Solely to Define Relative Rights. The
provisions of this Article are and are intended solely for the purpose of
defining the relative rights of the Holders on the one hand and the holders of
Senior Debt on the other hand. Nothing contained in this Article or elsewhere in
this Indenture or in the Securities is intended to or shall (a) impair, as among
the Company or any Guarantor, as applicable, its creditors other than holders of
Senior Debt and the Holders of the Securities with the Guarantees endorsed
thereon, the obligation of the Company or any Guarantor, as applicable, which is
absolute and unconditional (and which, subject to the rights under this Article
of the holders of Senior Debt, is intended to rank equally with all other
general obligations of the Company), to pay to the Holders of the Securities
with the Guarantees endorsed thereon the principal of (and premium, if any) and
interest on the Securities as and when the same shall become due and payable in
accordance with their terms; or (b) affect the relative rights against the
Company or any Guarantor, as applicable, of the Holders of the Securities with
the Guarantees endorsed thereon and creditors of the Company or any

                                     -100-
<PAGE>   109
Guarantor, as applicable, other than the holders of Senior Debt; or (c) prevent
the Trustee or the Holder of any Security with the Guarantees endorsed thereon
from exercising all remedies otherwise permitted by applicable law upon default
under this Indenture, subject to the rights, if any, under this Article of the
holders of Senior Debt to receive cash, property and securities otherwise
payable or deliverable to the Trustee or such Holder.

                  Section 15.7. Trustee to Effectuate Subordination. Each Holder
of a Security by his acceptance thereof authorizes and directs the Trustee on
his behalf to take such action as may be necessary or appropriate to effectuate
the subordination provided in this Article and appoints the Trustee his
attorney-in-fact for any and all such purposes.

                  Section 15.8. No Waiver of Subordination Provisions. No right
of any present or future holder of any Senior Debt 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 any Guarantor or by any act
or failure to act, in good faith, by any such holder, or by any noncompliance by
the Company or any Guarantor with the terms, provisions and covenants of this
Indenture, regardless of any knowledge thereof any such holder may have or be
otherwise charged with.

                  Without in any way limiting the generality of the foregoing
paragraph, the holders of Senior Debt may, at any time and from time to time,
without the consent of or notice to the Trustee or the Holders of the
Securities, without incurring responsibility to the Holders of the Securities
and without impairing or releasing the subordination provided in this Article or
the obligations hereunder of the Holders of the Securities to the holders of
Senior Debt, 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 or
increase, Senior Debt, or otherwise amend or supplement in any manner Senior
Debt or any instrument evidencing the same or any agreement under which Senior
Debt is outstanding; (ii) sell, exchange, release or otherwise deal with any
property pledged, mortgaged or otherwise securing Senior Debt; (iii) release any
Person liable in any manner for the collection of Senior Debt; and (iv) exercise
or refrain from exercising any rights against the Company, the Guarantors and
any other Person.

                  Section 15.9. Notice to Trustee. The Company shall give prompt
written notice to the Trustee of any fact known to the Company which would
prohibit the making of any payment to or by the Trustee in respect of the
Securities or any of the Senior Subordinated Guarantees. Notwithstanding the
provisions of this Article 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 to or by the Trustee in respect of the
Securities or any of the Senior Subordinated Guarantees, unless and until the
Trustee shall have received written notice thereof from the Company or a holder
of Senior Debt or from any trustee therefor; and, prior to the receipt of any
such

                                     -101-
<PAGE>   110
written notice, the Trustee, subject to the provisions of Section 6.1, shall be
entitled in all respects to assume that no such facts exist, provided that
nothing in this Section 15.9 shall impair the subordination provisions of this
Article Fourteen.

                  Subject to the provisions of Section 6.1, the Trustee shall be
entitled to rely on the delivery to it of a written notice by a Person
representing himself to be a holder of Senior Debt (or a trustee, representative
or agent therefor) to establish that such notice has been given by a holder of
Senior Debt (or a trustee, representative or agent therefor). 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 Debt to participate in
any payment or distribution pursuant to this Article, the Trustee may request
such Person to furnish evidence to the reasonable satisfaction of the Trustee as
to the amount of Senior Debt held by such Person, the extent to which such
Person is entitled to participate in such payment or distribution and any other
facts pertinent to the rights of such Person under this Article, 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 15.10. Reliance on Judicial Order or Certificate of
Liquidating Agent. Upon any payment or distribution of assets or securities of
the Company or any Guarantor referred to in this Article, the Trustee, subject
to the provisions of Section 6.1, and the Holders of the Securities shall be
entitled to rely upon any order or decree entered by any court of competent
jurisdiction in which such Proceeding is pending, or a certificate of the
trustee in bankruptcy, receiver, liquidating trustee, custodian, assignee for
the benefit of creditors, agent or other Person making such payment or
distribution, delivered to the Trustee or to the Holders of Securities, for the
purpose of ascertaining the Persons entitled to participate in such payment or
distribution, the holders of the Senior Debt and other indebtedness of the
Company or any Guarantor, 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.

                  Section 15.11. Trustee Not Fiduciary for Holders of Senior
Debt. The Trustee shall not be deemed to owe any fiduciary duty to the holders
of Senior Debt and shall not be liable to any such holders if it shall in good
faith mistakenly pay over or distribute to Holders of Securities or to the
Company or any Guarantor or to any other Person cash, property or securities to
which any holders of Senior Debt shall be entitled by virtue of this Article or
otherwise.

                  Section 15.12. Rights of Trustee as Holder of Senior Debt;
Preservation of Trustee's Rights. The Trustee in its individual capacity shall
be entitled to all the rights set forth in this Article with respect to any
Senior Debt which may at any time be held by

                                     -102-
<PAGE>   111
it, to the same extent as any other holder of Senior Debt, and nothing in this
Indenture shall deprive the Trustee of any of its rights as such holder.

                  Nothing in this Article shall apply to claims of, or payments
to, the Trustee under or pursuant to Section 6.7.

                  Section 15.13. Article Applicable to Paying Agents. In case at
any time any Paying Agent other than the Trustee shall have been appointed by
the Company and be then acting hereunder, the term "Trustee" as used in this
Article shall in such case (unless the context otherwise requires) be construed
as extending to and including such Paying Agent within its meaning as fully for
all intents and purposes as if such Paying Agent were named in this Article in
addition to or in place of the Trustee; provided, however, that Section 15.12
shall not apply to the Company or any Affiliate of the Company if it or such
Affiliate acts as Paying Agent.

                  Section 15.14. Defeasance of this Article 15. The
subordination of the Securities and the Senior Subordinated Guarantees provided
by this Article 15 is expressly made subject to the provisions for defeasance or
covenant defeasance in Article 4 and, anything herein to the contrary
notwithstanding, upon the effectiveness of any such defeasance or covenant
defeasance, the Securities then Outstanding and the Senior Subordinated
Guarantees relating thereto shall thereupon cease to be subordinated pursuant to
this Article 15.

                                   ARTICLE 16

                          SENIOR SUBORDINATED GUARANTEE

                  Section 16.1. Senior Subordinated Guarantee. Each of Allied
and the Subsidiary Guarantors hereby jointly and severally unconditionally
guarantees to each Holder of a Security authenticated and delivered by the
Trustee, and to the Trustee on behalf of such Holder, the due and punctual
payment of the principal of (and premium, if any) and interest on such Security
when and as the same shall become due and payable, whether at the Stated
Maturity or by acceleration, call for redemption, purchase or otherwise, in
accordance with the terms of such Security and of this Indenture. In case of the
failure of the Company punctually to make any such payment, each of Allied and
the Subsidiary Guarantors hereby jointly and severally agrees to cause such
payment to be made punctually when and as the same shall become due and payable,
whether at the Stated Maturity or by acceleration, call for redemption, purchase
or otherwise, and as if such payment were made by the Company.

                  Each of the Guarantors hereby jointly and severally agrees
that its obligations hereunder shall be unconditional, irrespective of the
validity, regularity or

                                     -103-
<PAGE>   112
enforceability of any Security or this Indenture, the absence of any action to
enforce the same, any creation, exchange, release or nonperfection of any Lien
on any collateral for, or any release or amendment or waiver of any term of any
other Guarantee of, or any consent to departure from any requirement of any
other Guarantee, of all or any of the Securities, the election by the Trustee or
any of the Holders in any proceeding under Chapter 11 of Title 11 of the United
States Code (the "Bankruptcy Code") of the application of Section 1111(b)(2) of
the Bankruptcy Code, any borrowing or grant of a security interest by the
Company, as debtor in possession, under Section 364 of the Bankruptcy Code, the
disallowance, under Section 502 of the Bankruptcy Code, of all or any portion of
the claims of the Trustee or any of the Holders for payment of any of the
Securities, any waiver or consent by the Holder of any Security or by the
Trustee with respect to any provisions thereof or of this Indenture, the
obtaining of any judgment against the Company or any action to enforce the same
or any other circumstances which might otherwise constitute a legal or equitable
discharge or defense of a guarantor. Each of the Guarantors hereby waives the
benefits of diligence, presentment, demand of payment, any requirement that the
Trustee or any of the Holders protect, secure, perfect or insure any security
interest in or other Lien on any property subject thereto or exhaust any right
or take any action against the Company or any other Person or any collateral,
filing of claims with a court in the event of insolvency or bankruptcy of the
Company, any right to require a proceeding first against the Company, protest or
notice with respect to any Security or the indebtedness evidenced thereby and
all demands whatsoever, and covenants, that this Senior Subordinated Guarantee
will not be discharged in respect of any Security except by complete performance
of the obligations contained in such Security and in this Senior Subordinated
Guarantee. Each of the Guarantors hereby agrees that, in the event of a default
in payment of principal (or premium, if any) or interest on any Security,
whether at its Stated Maturity or by acceleration, call for redemption, purchase
or otherwise, legal proceedings may be instituted by the Trustee on behalf of,
or by, the Holder of such Security, subject to the terms and conditions set
forth in this Indenture, directly against each of the Guarantors to enforce its
Senior Subordinated Guarantee without first proceeding against the Company. Each
Guarantor agrees that if, after the occurrence and during the continuance of an
Event of Default, the Trustee or any of the Holders are prevented by applicable
law from exercising their respective rights to accelerate the maturity of the
Securities, to collect interest on the Securities or to enforce or exercise any
other right or remedy with respect to the Securities, or the Trustee or the
Holders are prevented from taking any action to realize on any collateral, such
Guarantor agrees to pay to the Trustee for the account of the Holders, upon
demand therefor, the amount that would otherwise have been due and payable had
such rights and remedies been permitted to be exercised by the Trustee or any of
the Holders.

<PAGE>   113
                  No provision of any Senior Subordinated Guarantee or Security
or of the Indenture shall alter or impair the Senior Subordinated Guarantee of
any Guarantor, which is absolute and unconditional, of the due and punctual
payment of the principal (and premium, if any) and interest on the Security upon
which such Senior Subordinated Guarantee is endorsed.

                  Each Guarantor shall be subrogated to all rights of the
Holders of the Securities upon which its Senior Subordinated Guarantee is
endorsed against the Company in respect of any amounts paid by such Guarantor on
account of such Security pursuant to the provisions of its Senior Subordinated
Guarantee or this Indenture; provided, however, that no Guarantor shall be
entitled to enforce or to receive any payments arising out of, or based upon,
such right of subrogation until the principal of (and premium, if any) and
interest on all Securities issued hereunder shall have been paid in full.

                  Each Senior Subordinated Guarantee shall remain in full force
and effect and continue to be effective should any petition be filed by or
against the Company for liquidation or reorganization, should the Company become
insolvent or make an assignment for the benefit of creditors or should a
receiver or trustee be appointed for all or any significant part of the assets
of the Company and shall, to the fullest extent permitted by law, continue to be
effective or be reinstated, as the case may be, if at any time payment and
performance of the Securities is, pursuant to applicable law, rescinded or
reduced in amount, or must otherwise be restored or returned by any obligee on
the Securities, whether as a "voidable preference," "fraudulent transfer" or
otherwise, all as though such payment or performance had not been made. In the
event that any payment, or any part thereof, is rescinded, reduced, restored or
returned, the Securities shall, to the fullest extent permitted by law, be
reinstated and deemed reduced only by such amount paid and not so rescinded,
reduced, restored or returned.

                  No stockholder, officer, director, employer or incorporator,
past, present or future, of any Guarantor, as such, shall have any personal
liability under any Senior Subordinated Guarantee by reason of his, her or its
status as such stockholder, officer, director, employer or incorporator.

                  To the extent that any Subsidiary Guarantor shall be required
to pay any amounts on account of the Securities pursuant to its Senior
Subordinated Guarantee in excess of the greater of (i) the amount of the
economic benefit actually received by such Subsidiary Guarantor from the
issuance of the Securities and (ii) an amount calculated as the product of (A)
the aggregate amount payable by the Subsidiary Guarantors on account of the
Securities pursuant to their Senior Subordinated Guarantees times (B) the
proportion (expressed as a fraction) that such Subsidiary Guarantor's net worth
at the date enforcement of its Senior Subordinated Guarantee is sought bears to
the aggregate net

                                     -105-
<PAGE>   114
worth of all Subsidiary Guarantors at such date, then such Subsidiary Guarantor
shall be reimbursed by the other Subsidiary Guarantors for the amount of such
excess, pro rata, based upon the respective net worth of such other Subsidiary
Guarantors at the date enforcement of its Senior Subordinated Guarantees is
sought. This paragraph is intended only to define the relative rights of the
Subsidiary Guarantors as among themselves, and nothing set forth in this
paragraph is intended to or shall impair the joint and several obligations of
the Guarantors under their respective Senior Subordinated Guarantees.

                  The Guarantors shall have the right to seek contribution from
any nonpaying Guarantor so long as the exercise or such right does not impair
the rights of the Holders under any Senior Subordinated Guarantee.

                  Section 16.2. Execution and Delivery of Senior Subordinated
Guarantees. The Senior Subordinated Guarantees to be endorsed on the Securities
shall include the terms of the Senior Subordinated Guarantee set forth in
Section 16.1 and any other terms that may be set forth in the form established
pursuant to Section 2.3. Each of the Guarantors hereby agrees to execute its
Senior Subordinated Guarantee, in a form established pursuant to Section 2.3, to
be endorsed on each Security authenticated and delivered by the Trustee.

                  The Senior Subordinated Guarantee shall be executed on behalf
of each respective Guarantor by any one of such Guarantor's Chairman of the
Board, Vice Chairman of the Board, President or Vice Presidents, attested by its
Secretary or Assistant Secretary. The signature of any or all of these officers
on the Senior Subordinated Guarantee may be manual or facsimile and may be
pursuant to a duly executed power of attorney.

                  A Senior Subordinated Guarantee bearing the manual or
facsimile signatures of individuals who were at any time the proper officers of
a Guarantor shall bind such Guarantor, notwithstanding that such individuals or
any of them have ceased to hold such offices prior to the authentication and
delivery of the Security on which such Senior Subordinated Guarantee is endorsed
or did not hold such offices at the date of such Senior Subordinated Guarantee.

                  The delivery of any Security by the Trustee, after the
authentication thereof hereunder, shall constitute due delivery of the Senior
Subordinated Guarantee endorsed thereon on behalf of the Guarantors. Each of the
Guarantors hereby jointly and severally agrees that its Senior Subordinated
Guarantee set forth in Section 16.1 shall remain in full force and effect
notwithstanding any failure to endorse a Senior Subordinated Guarantee on any
Security.

                  Section 16.3. Subsidiary Guarantors May Consolidate, Etc., on
Certain Terms. Except as may be provided in Section 16.4 and in Articles 7 and
9, nothing contained in this Indenture or in any of the Securities shall prevent
any consolidation or merger of a Subsidiary Guarantor with or into the Company
or a Guarantor or shall prevent any sale or conveyance of the property of a
Subsidiary Guarantor as an entirety or substantially as an entirety to the
Company or a Guarantor.

                  Section 16.4. Release of Guarantors. (a) Concurrently with any
consolidation or merger of a Subsidiary Guarantor or any sale or conveyance of
the property of a Subsidiary Guarantor as an entirety or substantially as an
entirety, in each case as permitted by Section 16.3, and upon delivery by the
Company to the Trustee of an Officers' Certificate and an Opinion of Counsel to
the effect that such consolidation, merger, sale or conveyance was made in
accordance with Section 16.3, the Trustee shall execute any documents reasonably
required in order to evidence the release of such Subsidiary Guarantor from its
obligations under its Subsidiary Guarantees endorsed on the Securities and under
this Article 16. Any Subsidiary Guarantor not released from its obligations
under its Subsidiary Guarantees endorsed on the Securities and under this
Article 16 shall remain liable for the full amount of principal of (and premium,
if any) and interest on the Securities and for the other obligations of a
Subsidiary Guarantor under its Subsidiary Guarantees endorsed on the Securities
and under this Article 16

                  (b) Concurrently with the defeasance of the Securities under
Section 4.4 or the covenant defeasance of the Securities under Section 4.5, the
Guarantors shall be released from all of their obligations under their Senior
Subordinated Guarantees endorsed on the Securities and under this Article 16.

                  (c) Upon the consummation of any transaction (whether
involving a sale or other disposition of securities, a merger or otherwise)
whereby any Subsidiary Guarantor ceases to be a Restricted Subsidiary and which
transaction is otherwise in compliance with the provisions of this Indenture,
such Subsidiary Guarantor shall automatically be released from all obligations
under its Subsidiary Guarantees endorsed on the Securities and under this
Article 16.

                  Section 16.5. Additional Guarantors. The Company shall cause
each Person that becomes a Restricted Subsidiary after the date of this
Indenture [(other than Med Track)], upon becoming a Restricted Subsidiary, to
become a Subsidiary Guarantor with respect to the Securities. Any such Person
shall become a Subsidiary Guarantor by executing and delivering to the Trustee
(a) a supplemental indenture, in form and substance satisfactory to the Trustee,
which subjects such Person to the provisions of this Indenture as a Subsidiary
Guarantor and (b) an Opinion of Counsel to the effect that such supplemental
indenture has been duly authorized and executed by such Person and constitutes
the legal, valid, binding and enforceable obligation of such Person (subject to
such customary exceptions concerning creditors' rights and equitable principles
as may be acceptable to the Trustee in its discretion).
