                              EMPLOYMENT AGREEMENT

                    EMPLOYMENT AGREEMENT, made effective as of the 21st day of
September, 1999 between RARE MEDIUM GROUP, INC. ("RMGI" or the "Company"), a
Delaware corporation, with its principal offices at 565 Fifth Avenue, 29th
Floor, New York, NY 10017 and Jeffrey J. Kaplan, an individual residing at 310
River Road, Grandview, NY 10960 (the "Employee").

                    In consideration of their mutual promises and covenants set
forth herein, and intending to be legally bound hereby, Company and Employee
agree as follows:

                    1.       Employment. The Company hereby employs the Employee
and the Employee accepts such employment on the terms and conditions hereinafter
set forth.

                    2.       Term. The term of this Agreement shall begin on
September 21, 1999 and shall terminate on September 20, 2003, unless sooner
terminated in accordance with Paragraph 6 hereof.

                    3.       Duties. The Employee is engaged hereunder as
Executive Vice President and Chief Financial Officer of the Company and he
agrees to perform the duties and services incident to that position, or such
other or further duties and services of a similar nature as may be reasonably
required of him by the Board of Directors of the Company or the Board's
designee. Employee shall at all times be subject to the supervision of the Board
of Directors of the Company and of such other persons as the Board may
designate.

                             The Employee shall devote his full business time,
attention, energies and best efforts to the performance of his duties hereunder
and to the promotion of the business and interests of the Company and of any
corporate subsidiaries or affiliated companies. The foregoing shall not be
construed, however, as preventing the Employee from investing his assets in such
form or manner as will not require services on the part of the Employee in the
operations of the business in which such investment is made and provided such
business is not in competition with the Company or, if in competition, such
business has a class of securities registered under the Securities Exchange Act
of 1934 and the interest of Employee therein is solely that of an investor
owning not more than 3% of any class of the outstanding equity securities of
such business.

                             The Employee recognizes that he will be required by
the Company to travel outside of the New York metropolitan area in order to
perform a portion of the services to be rendered hereunder, but the nature or
extent of such traveling shall not be such as to make it reasonably necessary
for the Employee to relocate his permanent residence from the New York
metropolitan area.

                    4.       Compensation: Expenses.

                             (a)     Base Salary. The Employee shall be paid a
salary at the rate of not less than $225,000 per year (the "Base Salary"). The
Base Salary shall be paid in installments in arrears in accordance with the
Company's regular payroll practices. The Company may, in its discretion,
increase the Employee's Base Salary and his other compensation provided for
herein. Employee shall be entitled to annual increases in Base Salary as
determined by the Board of Directors, provided however, that such increase shall
not be less than 4% per annum.

                             (b)     Fringe Benefits.

                                      (i)  The Employee shall be entitled to
participate in all current and future insurance, vacation and other fringe
benefit programs of the Company to the extent and on the same terms and
conditions as are accorded to other management employees of the Company,
provided, however, that nothing herein shall be deemed to require grants or
awards to Employee under any benefit plans which provide for awards or grants at
the discretion of the Board of Directors or of any committee or administrator ,
and that entitlement to vacations shall be governed solely by clause (ii) of
this subparagraph (b).

                                        (ii)  The Employee shall be entitled in
each calendar year commencing with 2000 to a vacation of four (4) weeks, without
loss of or reduction in his compensation. Each vacation shall be taken by the
Employee at such time or times as agreed upon by the Company and Employee. Any
portion of Employee's vacation not used during any calendar year shall be
carried forward, provided that Employee may not take more than six (6) weeks
vacation during any calendar year. For the remainder of calendar year 1999,
Employee shall be entitled to one (1) week of vacation.

                             (c)      Business Expenses. The Company will pay,
or reimburse the Employee for, all ordinary and reasonable out-of-pocket
business expenses incurred by Employee in connection with his performance of
services hereunder during the Employment Term in accordance with the Company's
expense authorization and approval procedures then in effect upon presentation
to the Company of an itemized account and written proof of such expenses.
Employee shall also have a monthly nonaccountable expense allowance of $1,500.

                             (d)      Stock Options.  Concurrently with the
execution of this Agreement, RMGI shall grant to Employee, Stock Options to
purchase an aggregate of 350,000 shares of Common Stock of RMGI at the exercise
price equal to the closing price on the day the Board of Directors of RMGI
approves the issuance of the options which shall become exercisable 87,500 after
the first anniversary; an additional 87,500 on each 12-month anniversary
thereafter all over a period of four (4) years from the date of grant. The
options shall expire ten (10) years from the date

                                      (2)
<PAGE>

of grant. Such options shall entitle the Holder to exercise them through a
service without requiring that cash be advanced by the Holder and the Option
Agreement shall so provide.

                                    If the employee is terminated without cause,
50% of all outstanding options not vested shall vest, and all vested options
shall be exercisable through their initial expiration date.

                             (e)      Entire Compensation. The compensation
provided for in this Agreement is in full payment of the services to be rendered
by the Employee to the Company hereunder, except that Employee shall be eligible
to participate in any performance based bonus plan in effect at the relevant
time as determined by the Board of Directors.

                    5.       Death or Total Disability of the Employee.

                             (a)        Death. In the event of the death of the
Employee during the term of this Agreement, this Agreement shall terminate
effective as of the date of the Employee's death, and the Company shall not have
any further obligation or liability hereunder except that the Company shall pay
to Employee's designated beneficiary or, if none, his estate the portion, if
any, of the Employee's Base Salary for the period up to the Employee's date of
death which remains unpaid; and 50% of unvested stock options shall vest and the
employee's named beneficiary shall have , through their initial expiration date,
to exercise all vested options.

                             (b)        Total Disability. In the event of the
Total Disability (as that term is hereinafter defined) of the Employee, the
Company shall have the right to terminate the Employee's employment hereunder by
giving the Employee 10 days' written notice thereof and, upon expiration of such
10-day period, the Company shall not have any further obligation or liability
under this Agreement except that the Company shall pay to the Employee the
portion, if any, of the Employee's Base Salary for the period up to the date of
termination which remains unpaid, provided that if the Employee, during any
period of disability, receives any periodic payments representing lost
compensation under any health and accident policy or under any salary
continuation insurance policy, the premiums for which have been paid by the
Company, the amount of Base Salary that the Employee would be entitled to
receive from the Company during such period of disability shall be decreased by
the amounts of such payments and 50% of unvested stock options shall continue to
vest according to their regular schedule and all vested options shall be
exercisable through their initial expiration date. (This should be interpreted
to mean 43,750 shares of each 87,500 share block yet to be vested.)

                    The term "Total Disability," when used herein, shall mean a
mental, emotional or physical condition which either (i) has rendered the
Employee for a period of 90 consecutive days, or for a total of 150 days during
any period of 24 consecutive months, during the term of this Agreement, or (ii)
in the reasonable opinion of the Company is expected to render the Employee, for
a period of 3 months, unable or incompetent to carry out, on a substantially
full-time basis, the job

                                      (3)
<PAGE>

responsibilities he held or tasks that he was assigned at the time the
disability was incurred. The Employee agrees, in the event of any dispute as to
the determination made pursuant to this paragraph, to submit to a physical or
other examination by a licensed physician selected by the Company, the cost of
which examination shall be paid by the Company.

                    6.       Termination of Employment. In addition to
termination pursuant to paragraph 5, the Company may discharge the Employee and
thereby terminate his employment hereunder for the following reasons ("for
cause"): (i) habitual intoxication which materially affects the Employee's
performance; (ii) drug addiction; (iii) conviction of a felony materially
adversely affecting the Company or the Employee's ability to perform his duties
hereunder; (iv) adjudication as an incompetent; or (v) misappropriation of
corporate funds or other acts of dishonesty; or (vi) the Employee's willful
breach of this Agreement in any other material respect which are not remedied
within 30 days from the event.

                    In the event that the Company shall discharge the Employee
pursuant to this paragraph 6, the Company shall not have any further obligations
or liability under this Agreement.

                    In the event that the Company shall discharge the Employee
other than "For Cause" Employee shall continue to receive his then current Base
Salary for a period of 12 months after such discharge and except as set forth in
this sentence, the Company shall not have any further obligations or liability
under this Agreement, except with respect to the provisions set forth in Section
4(d) of this Agreement.

                    In the event of a "Change in Control" of the Company as
defined below, at Employee's option, Employee shall have the right to terminate
this Agreement. Upon said election to terminate by Employee: (a) Employee shall
receive a lump sum payment from the Company which shall be equal to (i) the
total of Employee's salary plus all incentive compensation for the remaining
portion of the term of this Agreement, plus (ii) the cash value of all benefits
which would have been received by the Employee for the remaining portion of the
term of this Agreement, plus (iii) all unexercised stock options (whether or not
vested).

                    For purposes of this Agreement, a "Change of Control" means
the happening of any of the following: When any "person" as defined in Section
3(a)(9) of the Securities Exchange Act of 1934 ("Exchange Act") and as used in
Section 13(d) and 14(d) thereof, including a "group" as defined in Section 13(d)
of the Exchange Act but excluding RMGI, any subsidiary and any employee benefit
plan sponsored or maintained by RMGI, or any subsidiary (including any trustee
of such plan acting as trustee), and excluding Apollo Management and its
affiliates, directly or indirectly becomes a "beneficial owner" (as defined in
Rule 13d-3 under the Exchange Act, as amended from time to time), of securities
of RMGI representing 50 percent or more of the combined voting power of RMGI
representing 50 percent or more of RMGI's then outstanding securities including
the options written relating to a financing by RMGI.

                    7.       Non-Disclosure.

                             (a)  Non-Disclosure. The Employee recognizes and
acknowledges that he will have access to certain confidential information of the
Company and that such information constitutes valuable, special and unique
property of the Company. The Employee agrees that he will not, for any reason or
purpose whatsoever, during or after the term of his employment, use any of such
confidential information or disclose any of such confidential information to any
party without express authorization of the Company, except as necessary in the
ordinary course of performing his duties hereunder. The obligation of
confidentiality imposed by this subparagraph shall not apply to information
which appears in issued patents or printed publications or which otherwise
becomes generally known in the industry through no act of the Employee in breach
of this Agreement.

                             (b)  Inventions, Designs and Product Developments.
All inventions, discoveries, concepts, improvements, formulas, processes,
devices, methods, innovations, designs, ideas and product developments
(collectively, the "Developments"), developed or conceived by Employee, solely
or jointly with others, whether or not patentable or copyrightable, at any time
during the Employment Term or within one year after the termination hereof and
which relate to the actual or planned business activities of the Company and all
of the Employee's right, title and interest therein, shall be the exclusive
property of the Company. The Employee hereby assigns, transfers and conveys to
the Company all of his right, title and interest in and to any and all such
Developments. Employee shall disclose fully, as soon as practicable and in
writing, all Developments to the Board of Directors of the Company. At any time
and from time to time, upon the request of the Company, the Employee shall
execute and deliver to the Company any and all instruments, documents and
papers, give evidence and do any and all other acts which, in the opinion of
counsel for the Company, are or may be necessary or desirable to document such
transfer or to enable the Company to file and prosecute applications for and to
acquire, maintain and enforce any and all patents, trademark registrations or
copyrights under United States or foreign law with respect to any such
Developments or to obtain any extension, validation, reissue, continuance or
renewal of any such patent, trademark or copyright. The Company will be
responsible for the preparation of any such instruments, documents and papers
and for the prosecution of any such proceedings and will reimburse the Employee
for all reasonable expenses the Employee incurs upon authorization of the Board
of Directors of the Company.

                    8.       Noncompetition.  The Employee agrees that during
the term of this agreement and for a period of one (1) year thereafter, the
Employee shall not, unless acting pursuant hereto or with the prior written
consent of the Board of Directors of the Company, directly or indirectly:

                             (a)      solicit business from or perform services
for, any persons, company or other entity which at any time during the
Employee's employment by the Company is a client or customer of the Company if
such business or services are of the same general character as those engaged in
or performed by the Company;

                                      (5)
<PAGE>

                             (b)      solicit for employment or in any other
fashion hire any of the employees of the Company;

                             (c)      own, manage, operate, finance, join,
control or participate in the ownership, management, operation, financing or
control of, or be connected as an officer, director, employee, partner,
principal, agent, representative, consultant or otherwise with any business or
enterprise engaged in the business of designing, developing, and implementing
Internet web site applications and strategies, or any other business engaged in
by the Company for which Employee had primary responsibility, or any of its
affiliates (collectively, the "Business") within a radius of 20 miles from
Company's or any of Company's affiliates principal places of business (the
"Restricted Area");

                             (d)      use or permit his name to be used in
connection with, any business or enterprise engaged in the Business within the
Restricted Area; or

                             (e)      use the name of the Company or any name
similar thereto, but nothing in this clause shall be deemed, by implication, to
authorize or permit use of such name after expiration of such period;

provided, however, that this provision shall not be-construed to prohibit the
ownership by the Employee of not more than 3% of any class of the outstanding
equity securities of any corporation which is engaged in any of the foregoing
businesses having a class of securities registered pursuant to the Securities
Exchange Act of 1934. In the event that the provisions of this Section should
ever be adjudicated to exceed the time, geographic, service or product
limitations permitted by applicable law in any jurisdiction, then such
provisions shall be deemed reformed in such jurisdiction to the maximum time,
geographic, service or product limitations permitted by applicable law.

                    Notwithstanding the foregoing, if employee is terminated
other "than for cause" as defined in this Agreement, Employee's obligations
pursuant to provision 8(c) and 8(d) shall be terminated, but all other
subdivisions of this paragraph shall remain in effect.

                    9.       Equitable Relief; Survival.

                             (a)      The Employee acknowledges that the
restrictions contained in paragraphs 7(a), 7(b) and 8 hereof are, in view of the
nature of the business of the Company, reasonable and necessary to protect the
legitimate interests of the Company, and that any violation of any provisions of
those Sections will result in irreparable injury to the Company. The Employee
also acknowledges that the Company shall be entitled to temporary and permanent
injunctive relief, without the necessity of proving actual damages, and to an
equitable accounting of all earnings, profits and other benefits arising from
any such violation, which rights shall be cumulative and in

                                      (6)
<PAGE>

addition to any other rights or remedies to which the Company may be entitled.
In the event of any such violation, the Company shall be entitled to commence an
action for temporary and permanent injunctive relief and other equitable relief
in any court of competent jurisdiction and Employee further irrevocably submits
to the jurisdiction of any New York State court or Federal court sitting in the
Southern District of New York over any suit, action or proceeding arising out of
or relating to paragraph 7 or 8. The Employee hereby waives, to the fullest
extent permitted by law, any objection that he may now or hereafter have to such
jurisdiction or to the venue of any such suit, action or proceeding brought in
such a court and any claim that such suit, action or proceeding has been brought
in any inconvenient forum. Effective service of process may be made upon the
Employee by mail under the notice provisions contained in paragraph 12 hereof.

                             (b)      Survival of Covenants. The provisions of
paragraphs 7 and 8 shall survive the termination of this Agreement.

                    10.      Remedies Cumulative; No Waiver. No remedy conferred
upon the Company by this Employment Agreement is intended to be exclusive of any
other remedy, and each and every such remedy shall be cumulative and shall be in
addition to any other remedy given hereunder or now or hereafter existing at law
or in equity. No delay or omission by the Company in exercising any right,
remedy or power hereunder or existing at law or in equity shall be construed as
a waiver thereof-, and any such right, remedy or power may be exercised by the
Company from time to time and as often as may be deemed expedient or necessary
by the Company in its sole discretion.

                    11.      Enforceability. If any provision of this Agreement
shall be invalid or unenforceable, in whole or in part, then such provision
shall be deemed to be modified or restricted to the extent and in the manner
necessary to render the same valid and enforceable, or shall be deemed excised
from this Agreement, as the case may require, and this Agreement shall be
construed and enforced to the maximum extent permitted by law, as if such
provision had been originally incorporated herein as so modified or restricted,
or as if such provision had not been originally incorporated herein, as the case
may be.

                    12.      Notices. All notices, requests, demands, claims,
and other communications hereunder will be in writing. Any notice, request,
demand, claim, or other communication hereunder shall be deemed duly given if
(and then two business days after) it is sent by registered or certified mail,
return receipt requested, postage prepaid, and addressed to the intended

        "U.S. Government Obligation" has the meaning specified in Section 1304.

        "Vice President," when used with respect to the Company or the Trustee,
means any vice president, whether or not designated by a number or a word or
words added before or after the title "vice president."

SECTION 102. 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. Each such certificate or opinion shall be given in the form of an
Officers' Certificate, if to be given by an officer 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 shall include,

        (1) a statement that each individual signing such certificate or opinion
has read such covenant or condition 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 covenant or condition
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 103. 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 of counsel may be based,
insofar as it relates to factual

                                      -9-
<PAGE>   18

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 counsel knows,
or in the exercise of reasonable care should know, that the certificate or
opinion or representations with respect to such matters 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 104. ACTS OF HOLDERS; RECORD DATES.

        Any request, demand, authorization, direction, notice, consent, waiver
or other action provided or permitted by this Indenture to be given, made or
taken by Holders may be embodied in and evidenced by one or more instruments of
substantially similar tenor signed by such Holders in person or by agent duly
appointed in writing; and, except as herein otherwise expressly provided, such
action shall become effective when such instrument or instruments are delivered
to the Trustee and, where it is hereby expressly required, to the Company. The
Trustee shall promptly deliver to the Company copies of all such instrument or
instruments and records delivered to the Trustee. Such instrument or instruments
(and the action embodied therein and evidenced thereby) are herein sometimes
referred to as the "Act" of the Holders signing such instrument or instruments.
Proof of execution of any such instrument or of a writing appointing any such
agent shall be sufficient for any purpose of this Indenture and (subject to
Section 601) conclusive in favor of the Trustee and the Company, if made in the
manner provided in this Section.

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

        The ownership of Securities shall be proved by the Security Register.

        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 the Holder of every Security issued upon the registration of
transfer thereof or in exchange therefor or in lieu thereof in respect of
anything done, omitted or suffered to be done by the Trustee or the Company in
reliance thereon, whether or not notation of such action is made upon such
Security.

        The Company may set any day as a record date for the purpose of
determining the Holders of Outstanding Securities of any series entitled to
give, make or take any request, demand, authorization, direction, vote, notice,
consent, waiver or other action provided or permitted by this Indenture to be
given, made or taken by Holders of Securities of such series, provided that the

                                      -10-
<PAGE>   19

Company may not set a record date for, and the provisions of this paragraph
shall not apply with respect to, the giving or making of any notice,
declaration, request or direction referred to in the next paragraph. If any
record date is set pursuant to this paragraph, the Holders of Outstanding
Securities of the relevant series on such record date, and no other Holders,
shall be entitled to take the relevant action, whether or not such Holders
remain Holders after such record date; provided that no such action shall be
effective hereunder unless taken on or prior to the applicable Expiration Date
by Holders of the requisite principal amount of Outstanding Securities of such
series on such record date. Nothing in this paragraph shall be construed to
prevent the Company from setting a new record date for any action for which a
record date has previously been set pursuant to this paragraph (whereupon the
record date previously set shall automatically and with no action by any Person
be canceled and of no effect), and nothing in this paragraph shall be construed
to render ineffective any action taken by Holders of the requisite principal
amount of Outstanding Securities of the relevant series on the date such action
is taken. Promptly after any record date is set pursuant to this paragraph, the
Company, at its own expense, shall cause notice of such record date, the
proposed action by Holders and the applicable Expiration Date to be given to the
Trustee in writing and to each Holder of Securities of the relevant series in
the manner set forth in Section 106.

        The Trustee may set any day as a record date for the purpose of
determining the Holders of Outstanding Securities of any series entitled to join
in the giving or making of (i) any Notice of Default, (ii) any declaration of
acceleration referred to in Section 502, (iii) any request to institute
proceedings referred to in Section 507(2) or (iv) any direction referred to in
Section 512, in each case with respect to Securities of such series. If any
record date is set pursuant to this paragraph, the Holders of Outstanding
Securities of such series on such record date, and no other Holders, shall be
entitled to join in such notice, declaration, request or direction, whether or
not such Holders remain Holders after such record date; provided that no such
action shall be effective hereunder unless taken on or prior to the applicable
Expiration Date by Holders of the requisite principal amount of Outstanding
Securities of such series on such record date. Nothing in this paragraph shall
be construed to prevent the Trustee from setting a new record date for any
action for which a record date has previously been set pursuant to this
paragraph (whereupon the record date previously set shall automatically and with
no action by any Person be canceled and of no effect), and nothing in this
paragraph shall be construed to render ineffective any action taken by Holders
of the requisite principal amount of Outstanding Securities of the relevant
series on the date such action is taken. Promptly after any record date is set
pursuant to this paragraph, the Trustee, at the Company's expense, shall cause
notice of such record date, the proposed action by Holders and the applicable
Expiration Date to be given to the Company in writing and to each Holder of
Securities of the relevant series in the manner set forth in Section 106.

        With respect to any record date set pursuant to this Section, the party
hereto which sets such record dates may designate any day as the "Expiration
Date" and from time to time may change the Expiration Date to any earlier or
later day; provided that no such change shall be effective unless notice of the
proposed new Expiration Date is given to the other party hereto in writing, and
to each Holder of Securities of the relevant series in the manner set forth in
Section 106, on or prior to the existing Expiration Date. If an Expiration Date
is not designated with respect to any record date set pursuant to this Section,
the party hereto which set such record date shall be deemed to have initially

                                      -11-
<PAGE>   20

designated the 180th day after such record date as the Expiration Date with
respect thereto, subject to its right to change the Expiration Date as provided
in this paragraph. Notwithstanding the foregoing, no Expiration Date shall be
later than the 180th day after the applicable record date.

        Without limiting the foregoing, a Holder entitled hereunder to 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 such principal amount.

SECTION 105. 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 (or by
facsimile transmission ((212) 815-5915), provided that oral confirmation of
receipt shall have been received) to or with the Trustee at its Corporate Trust
Office, Attention: Corporate Trust Administration, 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 the Company addressed to it
at the address of its principal office specified in the first paragraph of this
instrument or at any other address previously furnished in writing to the
Trustee by the Company, Attention: Chief Financial Officer.

SECTION 106. NOTICE TO HOLDERS; WAIVER.

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

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

SECTION 107. CONFLICT WITH TRUST INDENTURE ACT.

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

SECTION 108. EFFECT OF HEADINGS AND TABLE OF CONTENTS.

its successors and assigns, whether so expressed or not.

SECTION 110. SEPARABILITY CLAUSE.

        In case any provision in this Indenture or in 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 111. BENEFITS OF INDENTURE.

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

SECTION 112. GOVERNING LAW.

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

SECTION 113. LEGAL HOLIDAYS.

        In any case where any Interest Payment Date, Redemption Date or Stated
Maturity of any Security or the last date on which a Holder has the right to
convert a Security at a particular conversion price shall not be a Business Day
at any Place of Payment, then (notwithstanding any other provision of this
Indenture or of the Securities (other than a provision of any Security which
specifically states that such provision shall apply in lieu of this Section))
payment of interest or principal (and premium, if any) or, if applicable to a
particular series of Securities, conversion need not be made at such Place of
Payment on such date, but may be made on the next succeeding Business Day at
such Place of Payment with the same force and effect as if made on the Interest

Payment Date or Redemption Date, at the Stated Maturity or on such last day for
conversion, as the case may be.

SECTION 114. INDENTURE AND SECURITIES SOLELY CORPORATE OBLIGATIONS.

        No recourse for the payment of the principal of or premium, if any, or
interest on any Security, or for any claim based thereon or otherwise in respect
thereof, and no recourse under or upon any obligation, covenant or agreement of
the Company in this Indenture or in any supplemental indenture or in any
Security, or because of the creation of any indebtedness represented thereby,

director or subsidiary, as such, past, present or future, of the Company or of
any successor corporation, either directly or through the Company or any
successor corporation, whether by virtue of any constitution, statute or rule of

of transfer or exchange, but the Company may require payment of a sum sufficient
to cover any tax or other governmental charge payable in connection therewith.

Chairman of the Board, its Vice Chairman of the Board, its principal financial
officer, its President or one of its Vice Presidents, attested by its Treasurer,
its Assistant Treasurer, its Secretary or one of its Assistant Secretaries. The
signature of any of these officers on the Securities may be manual or facsimile.

        Securities bearing the manual or facsimile signatures of individuals who
were at any time the proper officers of the Company shall bind the Company,
notwithstanding that such individuals or any of them have ceased to hold such
offices prior to the authentication and delivery of such Securities or did not
hold such offices at the date of such Securities.

        At any time and from time to time after the execution and delivery of
this Indenture, the Company may deliver Securities of any series executed by the
Company to the Trustee for authentication, together with a Company Order for the
authentication and delivery of such Securities, and the Trustee in accordance
with the Company Order shall authenticate and deliver such Securities. If the
form or terms of the Securities of the series have been established by or
pursuant to one or more Board Resolutions as permitted by Sections 201 and 301,
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 601) shall be fully protected in
relying upon, a copy of such Board Resolution, the Officers' Certificate setting
forth the terms of the series and an Opinion of Counsel, with such Opinion of
Counsel stating,

                                      -26-
<PAGE>   35

        (1) if the form of such Securities has been established by or pursuant
to Board Resolution as permitted by Section 201, that such form has been
established in conformity with the provisions of this Indenture;

        (2) if the terms of such Securities have been established by or
pursuant to Board Resolution as permitted by Section 301, that such terms have
been established in conformity with the provisions of this Indenture; and

        (3) that such Securities, when authenticated and delivered by the
Trustee and issued by the Company 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 in accordance with their terms, subject
to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and
similar laws of general applicability relating to or affecting creditors' rights
and to general equity principles.

        If such form or terms have been so established, the Trustee shall not be
required to authenticate such Securities if the issue of such Securities
pursuant to this Indenture will affect the Trustee's own rights, duties or
immunities under the Securities and this Indenture or otherwise in a manner
which is not reasonably acceptable to the Trustee.

        Notwithstanding the provisions of Section 301 and of the preceding
paragraph, if all Securities of a series are not to be originally issued at one
time, it shall not be necessary to deliver the Officers' Certificate otherwise
required pursuant to Section 301 or the Company Order and Opinion of Counsel
otherwise required pursuant to such preceding paragraph at or prior to the
authentication of each Security of such series if such documents are delivered
at or prior to the authentication upon original issuance of the first Security
of such series to be issued.

        Each Security shall be dated the date of its authentication.

        No Security shall be entitled to any benefit under this Indenture or be
valid or obligatory for any purpose unless there appears on such Security a
certificate of authentication substantially in the form provided for herein
executed by the Trustee by manual signature, and such certificate upon any
Security shall be conclusive evidence, and the only evidence, that such Security
has been duly authenticated and delivered hereunder. 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 309, for all
purposes of this Indenture such Security shall be deemed never to have been
authenticated and delivered hereunder and shall never be entitled to the
benefits of this Indenture.

SECTION 304. 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 which are printed, lithographed, typewritten,
mimeographed or otherwise produced, in any authorized denomination,
substantially of the tenor of the definitive Securities in lieu of which they
are issued

                                      -27-
<PAGE>   36

and with such appropriate insertions, omissions, substitutions and other
variations as the officers executing such Securities may determine, as evidenced
by their execution of such Securities.

        If temporary Securities of any series are issued, the Company will cause
definitive Securities of that series to be prepared without unreasonable delay.
After the 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 in a Place of Payment for that series, without
charge to the Holder. Upon surrender for cancellation of any one or more
temporary Securities of any series, the Company shall execute and the Trustee
shall authenticate and deliver in exchange therefor one or more definitive
Securities of the same series, of any authorized denominations and of like tenor
and aggregate principal amount. 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 and tenor.

SECTION 305. REGISTRATION; REGISTRATION OF TRANSFER AND EXCHANGE.

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

        Upon surrender for registration of transfer of any Security of a series
at the office or agency of the Company 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 Securities
of the same series, of any authorized denominations and of like tenor and
aggregate principal amount.

        At the option of the Holder, Securities of any series may be exchanged
for other Securities of the same series, of any authorized denominations and of
like tenor and aggregate principal amount, upon surrender of the Securities to
be exchanged at such office or agency. Whenever any Securities are so
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 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 Security presented or surrendered for registration of transfer or
for exchange shall (if so required by the Company or the Security Registrar) be
duly endorsed, or be accompanied by a written instrument of transfer in form
satisfactory to the Company and the Security Registrar duly executed, by the
Holder thereof or its attorney duly authorized in writing.

                                      -28-
<PAGE>   37

        No service charge shall be made to the Holder for any registration of
transfer or 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 of transfer or exchange of Securities, other
than exchanges pursuant to Section 304, 906 or 1107 not involving any transfer.

        If the Securities of any series (or of any series and specified tenor)
are to be redeemed in part, neither the Company nor the Security Registrar shall
be required (A) to issue, register the transfer of or exchange any Securities of
that series (or of that series and specified tenor, as the case may be) during a
period beginning at the opening of business 15 days before the day of the
mailing of a notice of redemption of any such Securities selected for redemption
under Section 1103 and ending at the close of business on the day of such
mailing, or (B) to register the transfer of or exchange any Security so selected
for redemption in whole or in part, except the unredeemed portion of any
Security being redeemed in part.

        The provisions of Clauses (1), (2), (3) and (4) below shall apply only
to Global Securities:

        (1) Each Global Security authenticated under this Indenture shall be
registered in the name of the Depositary designated for such Global Security or
a nominee thereof and delivered to such Depositary or a nominee thereof or
custodian therefor, and each such Global Security shall constitute a single
Security for all purposes of this Indenture.

        (2) Notwithstanding any other provision in this Indenture, no Global
Security may be exchanged in whole or in part for Securities registered, and no
transfer of a Global Security in whole or in part may be registered, in the name
of any Person other than the Depositary for such Global Security or a nominee
thereof unless (A) such Depositary (i) has notified the Company that it is
unwilling or unable to continue as Depositary for such Global Security or (ii)
has ceased to be a clearing agency registered under the Exchange Act, (B) there
shall have occurred and be continuing an Event of Default with respect to such
Global Security or (C) there shall exist such circumstances, if any, in addition
to or in lieu of the foregoing as have been specified for this purpose as
contemplated by Section 301.

        (3) Subject to Clause (2) above, any exchange of a Global Security for
other Securities may be made in whole or in part, and all Securities issued in
exchange for a Global Security or any portion thereof shall be registered in
such names as the Depositary for such Global Security shall direct.

        (4) Every Security authenticated and delivered upon registration of
transfer of, or in exchange for or in lieu of, a Global Security or any portion
thereof, whether pursuant to this Section, Section 304, 306, 906 or 1107 or
otherwise, shall be authenticated and delivered in the form of, and shall be, a
Global Security, unless such Security is registered in the name of a Person
other than the Depositary for such Global Security or a nominee thereof.

                                      -29-

SECTION 306. MUTILATED, DESTROYED, LOST AND STOLEN SECURITIES.

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

        If there shall be delivered to the Company and the Trustee (i) evidence
to their satisfaction of the destruction, loss or theft of any Security 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 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, a new Security
of the same series and of like tenor and principal amount and bearing a number
not contemporaneously outstanding.

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

        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) connected therewith.

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

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

SECTION 307. PAYMENT OF INTEREST; INTEREST RIGHTS PRESERVED.

        Except as otherwise provided as contemplated by Section 301 with respect
to any series of Securities, interest on any 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.

        Any interest on any Security of any series which is payable, but is not
punctually paid or duly provided for, on any Interest Payment Date (herein
called "Defaulted Interest") shall forthwith cease to be payable to the Holder
on the relevant Regular Record Date by virtue of having been such

                                      -30-
<PAGE>   39

Holder, and such Defaulted Interest may be paid by the Company, at its election
in each case, as provided in Clause (1) or (2) below:

        (1) The Company may elect to make payment of any Defaulted Interest to
the Persons in whose names the Securities of such series (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 Security of such series
and the date of the proposed payment, and at the same time the Company shall
deposit with the Trustee an amount of money equal to the aggregate amount
proposed to be paid in respect of such Defaulted Interest or shall make
arrangements satisfactory to the Trustee for such deposit prior to the date of
the proposed payment, such money when deposited to be held in trust for the
benefit of the Persons entitled to such Defaulted Interest as in this Clause
provided. Thereupon the Trustee shall fix a Special Record Date for the payment
of such Defaulted Interest which 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
given to each Holder of Securities of such series in the manner set forth in
Section 106, not less than 10 days prior to such Special Record Date. Notice of
the proposed payment of such Defaulted Interest and the Special Record Date
therefor having been so mailed, such Defaulted Interest shall be paid to the
Persons in whose names the Securities of such series (or their respective
Predecessor Securities) are registered at the close of business on such Special
Record Date and shall no longer be payable pursuant to the following Clause (2).

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

        Subject to the foregoing provisions of this Section, 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.

        Subject to the provisions of Section 1402, in the case of any Security
(or any part thereof) which is converted 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 Stated Maturity or by declaration of acceleration 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 and such interest (whether or not punctually
paid or duly provided for) shall be paid to the Person in whose name that
Security (or any one or more Predecessor Securities) is registered at the close
of business on such

                                      -31-
<PAGE>   40

Regular Record Date. Except as otherwise expressly provided in the immediately
preceding sentence or in Section 1402, in the case of any Security (or any part
thereof) which is converted, interest whose Stated Maturity is after the date of
conversion of such Security (or such part thereof) shall not be payable.

SECTION 308. PERSONS DEEMED OWNERS.

        Prior to due presentment of a 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 Security is registered as the owner of such Security
for the purpose of receiving payment of principal of and any premium and
(subject to Section 307) any interest on such Security and for all other
purposes whatsoever, whether or not such 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.

SECTION 309. CANCELLATION.

        All Securities surrendered for payment, redemption, 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 canceled by it. The Company may at any time deliver to the
Trustee for cancellation any Securities previously authenticated and delivered
hereunder which the Company may have acquired in any manner whatsoever, and may
deliver to the Trustee (or to any other Person for delivery to the Trustee) for
cancellation any Securities previously authenticated hereunder which the Company
has not issued and sold, and all Securities so delivered shall be promptly
canceled by the Trustee. No Securities shall be authenticated in lieu of or in
exchange for any Securities canceled as provided in this Section, except as
expressly permitted by this Indenture. All canceled Securities held by the
Trustee shall be returned to the Company.

SECTION 310. COMPUTATION OF INTEREST.

        Except as otherwise specified as contemplated by Section 301 for
Securities of any series, interest on the Securities of each series shall be
computed on the basis of a 360-day year of twelve 30-day months.

SECTION 311. CUSIP NUMBERS.

        The Company in issuing the Securities may use "CUSIP" numbers (if then
generally in use), and, if so, the Trustee shall use "CUSIP" numbers in notices
of redemption as a convenience to Holders; provided that any such notice may
state that no representation is made as to the correctness of such numbers
either as printed on the 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. The Company will promptly notify
the Trustee of any change in the "CUSIP" numbers.

                           SATISFACTION AND DISCHARGE

SECTION 401. SATISFACTION AND DISCHARGE OF INDENTURE.

        This Indenture shall upon Company Request cease to be of further effect
(except as to any surviving rights of registration of transfer or exchange of
Securities herein expressly provided for), and the Trustee, at the expense of
the Company, shall execute proper instruments acknowledging satisfaction and
discharge of this Indenture, when

        (1) either

                (A) all Securities theretofore authenticated and delivered
        (other than (i) Securities which have been destroyed, lost or stolen and
        which have been replaced or paid as provided in Section 306 and (ii)
        Securities for whose payment money has theretofore been deposited in
        trust or segregated and held in trust by the Company and thereafter
        repaid to the Company or discharged from such trust, as provided in
        Section 1003) have been delivered to the Trustee for cancellation; or

                (B) all such Securities not theretofore delivered to the Trustee
        for cancellation

                        (i)have become due and payable, or

                        (ii) will become due and payable at their Stated
                Maturity within one year, or

                        (iii) are to be called for redemption within one year
                under arrangements satisfactory to the Trustee for the giving of
                notice of redemption by the Trustee in the name, and at the
                expense, of the Company,

        and the Company, in the case of (i), (ii) or (iii) above, has deposited
        or caused to be deposited with the Trustee as trust funds in trust for
        the purpose money in an amount sufficient, in the opinion of a
        nationally recognized firm of independent public accountants expressed
        in a written certification thereof to the Trustee, to pay and discharge
        the entire indebtedness on such Securities not theretofore delivered to
        the Trustee for cancellation, for principal and any premium and interest
        to the date of 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

                                      -33-
<PAGE>   42

        (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 have
been complied with.

        Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Company to the Trustee under Section 607, the obligations of
the Company to any Authenticating Agent under Section 614 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 402 and the last
paragraph of Section 1003 shall survive.

SECTION 402. APPLICATION OF TRUST MONEY.

        Subject to the provisions of the last paragraph of Section 1003, all
money deposited with the Trustee pursuant to Section 401 shall be held in trust
and applied by it, in accordance with the provisions of the Securities and this
Indenture, to the payment, either directly or through any Paying Agent
(including the Company acting as its own Paying Agent) as the Trustee may
determine, to the Persons entitled thereto, of the principal and any premium and
interest for whose payment such money has been deposited with the Trustee.

SECTION 501. EVENTS OF DEFAULT.

        "Event of Default," wherever used herein with respect to Securities of
any series, means any one of the following events (whatever the reason for such
Event of Default and whether it shall be occasioned by the provisions of Article
Fifteen or 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 any interest upon any Security of that
series when it becomes due and payable, and continuance of such default for a
period of 30 days; or

        (2) default in the payment of the principal of or any premium on any
Security of that series at its Maturity; or

        (3) default in the deposit of any sinking fund payment, when and as due
by the terms of a Security of that series; or

        (4) default in the performance, or breach, of any covenant or warranty
of the Company in this Indenture (other than a covenant or warranty a default in
whose performance or whose breach is elsewhere in this Section specifically
dealt with or which has expressly been included in this Indenture solely for the
benefit of series of Securities other than that series), and continuance of such
default or breach for a period of 90 days after there has been given, by
registered or certified mail, to

                                      -34-
<PAGE>   43

the Company by the Trustee or to the Company and the Trustee by the Holders of
at least 25% in principal amount of the Outstanding Securities of that series a
written notice specifying such default or breach and requiring it to be remedied
and stating that such notice is a "Notice of Default" hereunder; or

        (5) the entry by a court having jurisdiction in the premises of (A) a
decree or order for relief in respect of the Company in an involuntary case or
proceeding under any applicable Federal or State bankruptcy, insolvency,
reorganization or other similar law or (B) a decree or order adjudging the
Company bankrupt or insolvent, or approving as properly filed a petition seeking
reorganization, arrangement, adjustment or composition of or in respect of the
Company under any applicable Federal or State law, or appointing a custodian,
receiver, liquidator, assignee, trustee, sequestrator or other similar official
of the Company or of any substantial part of its property, or ordering the
winding up or liquidation of its affairs, and the continuance of any such decree
or order for relief or any such other decree or order unstayed and in effect for
a period of 90 consecutive days; or

        (6) the commencement by the Company of a voluntary case or proceeding
under any applicable Federal or State bankruptcy, insolvency, reorganization or
other similar law or of any other case or proceeding to be adjudicated a
bankrupt or insolvent, or the consent by it to the entry of a decree or order
for relief in respect of the Company in an involuntary case or proceeding under
any applicable Federal or State bankruptcy, insolvency, reorganization or other
similar law or to the commencement of any bankruptcy or insolvency case or
proceeding against it, or the filing by it of a petition or answer or consent
seeking reorganization or relief under any applicable Federal or State law, or
the consent by it to the filing of such petition or to the appointment of or
taking possession by a custodian, receiver, liquidator, assignee, trustee,
sequestrator or other similar official of the Company or of any substantial part
of its property, or the making by it of an assignment for the benefit of
creditors, or the admission by it in writing of its inability to pay its debts
generally as they become due, or the taking of corporate action by the Company
in furtherance of any such action; or

        (7) any other Event of Default provided with respect to Securities of
that series.

SECTION 502. ACCELERATION OF MATURITY; RESCISSION AND ANNULMENT.

        If an Event of Default (other than an Event of Default specified in
Section 501(5) or Section 501(6)) with respect to Securities of any series at
the time Outstanding occurs and is continuing, then in every such case the
Trustee or the Holders of not less than 25% in principal amount of the
Outstanding Securities of that series may declare the principal amount of all
the Securities of that series (or, if any Securities of that series are Original
Issue Discount Securities, such portion of the principal amount of such
Securities as may be specified by the terms thereof) to be due and payable
immediately, by a notice in writing to the Company (and to the Trustee if given
by Holders), and upon any such declaration such principal amount (or specified
amount) shall become immediately due and payable. If an Event of Default
specified in Section 501(5) or Section 501(6) with respect to Securities of any
series at the time Outstanding occurs, the principal amount of all the
Securities of that series (or, if any Securities of that series are Original
Issue Discount Securities, such portion of the principal amount of such
Securities as may be specified by

                                      -35-
<PAGE>   44

the terms thereof) shall automatically, and without any declaration or other
action on the part of the Trustee or any Holder, become immediately due and
payable. Any payments by the Company on the Securities following any such
acceleration will be subject to the subordination provisions of Article Fifteen
to the extent provided therein.

        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 principal amount of the
Outstanding Securities of that series, by written notice to the Company and the
Trustee, may rescind and annul such declaration and its consequences if

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

                (A) all overdue interest on all Securities of that series,

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

                (C) to the extent that payment of such interest is lawful,
        interest upon overdue interest at the rate or rates prescribed therefor
        in such Securities, and

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

        (2) all Events of Default with respect to 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 513.

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

SECTION 503. 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 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, the whole amount then due and payable on such
Securities for principal and any premium and interest and, to the extent that
payment of such interest shall be legally enforceable, interest on any overdue
principal and premium and on any overdue interest, at the rate or rates
prescribed

                                      -36-
<PAGE>   45

therefor in such Securities, and, in addition thereto, such further amount as
shall be sufficient to cover the costs and expenses of collection, including the
reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and counsel.

        If an Event of Default 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 enforce any other proper remedy.

SECTION 504. 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 607.

        No provision of this Indenture shall be deemed to authorize the Trustee
to authorize or consent to or accept or adopt on behalf of any Holder any plan
of reorganization, arrangement, adjustment or composition affecting the
Securities or the rights of any Holder thereof or to authorize the Trustee to
vote in respect of the claim of any Holder in any such proceeding; 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'

the Securities or the production thereof in any proceeding relating thereto, and
any such proceeding instituted by the Trustee shall be brought in its own name
as trustee of an express trust, and any recovery of judgment shall, after
provision for the payment of the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, be for the
ratable benefit of the Holders of the Securities in respect of which such

        No Holder of any Security of any series 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) such 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 not less than 25% in principal amount of the

indemnity against the costs, expenses and liabilities to be incurred in
compliance with such request;

and offer of indemnity has failed to institute any such proceeding; and

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

principal amount of the Outstanding Securities of that series;

it being understood and intended that no one or more of such Holders shall have
any right in any manner whatever by virtue of, or by availing of, any provision
of this Indenture to affect, disturb or prejudice the rights of any other 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 508. UNCONDITIONAL RIGHT OF HOLDERS TO RECEIVE PRINCIPAL, PREMIUM AND
             INTEREST AND TO CONVERT.

Security shall have the right, which is absolute and unconditional, to receive
payment of the principal of and any premium and (subject to Section 307)
interest on such Security on the respective Stated Maturities expressed in such
Security (or, in the case of redemption, on the Redemption Date), to convert
such Securities in accordance with Article Fourteen and to institute suit for
the enforcement of any such payment, and such rights shall not be impaired
without the consent of such Holder.

SECTION 509. 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 510. 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 306, no right or remedy herein conferred upon or reserved to the Trustee
or to the Holders is intended to be exclusive of any other right or remedy, and
every right and remedy shall, to the extent permitted by law, be cumulative and
in addition to every other right and remedy given hereunder or now or hereafter
existing at law or in equity or otherwise. The assertion or employment of any
right or remedy hereunder, or otherwise, shall not prevent the concurrent
assertion or employment of any other appropriate right or remedy.

SECTION 511. DELAY OR OMISSION NOT WAIVER.

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

SECTION 512. CONTROL BY HOLDERS.

        The Holders of a majority in principal amount of the Outstanding
Securities of any series shall have the right to direct the time, method and
place of conducting any proceeding for any remedy available to the Trustee, or

Securities of such series, provided that:

                                      -39-
<PAGE>   48

        (1) such direction shall not be in conflict with any rule of law or
with this Indenture and the Trustee shall not have determined that the action so
directed would be unjustly prejudicial to Holders of Securities of that series,
or any other series, not taking part in such direction; and

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

SECTION 513. WAIVER OF PAST DEFAULTS.

        The Holders of not less than a majority in principal amount of the
Outstanding Securities of any series may on behalf of the Holders of all the
Securities of such series waive any past default hereunder with respect to such
series and its consequences, except a default

        (1) in the payment of the principal of or any premium or interest on any
Security of such series, or

        (2) in respect of a covenant or provision hereof which under Article
Nine cannot be modified or amended 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 514. 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, including legal fees and
expenses, and may assess costs against any such party litigant, in the manner
and to the extent provided in the Trust Indenture Act; provided that neither
this Section nor the Trust Indenture Act shall be deemed to authorize any court
to require such an undertaking or to make such an assessment in any suit
instituted by the Company or in any suit for the enforcement of the right to
convert any Security in accordance with Article Fourteen.

SECTION 515. WAIVER OF USURY, STAY OR EXTENSION LAWS.

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

                                   THE TRUSTEE

SECTION 601. 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 602. 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 known to it 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 501(4) 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 603. CERTAIN RIGHTS OF TRUSTEE.

        Subject to the provisions of Section 601:

        (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;

                                      -41-
<PAGE>   50

        (4) the Trustee may consult with counsel of its selection and the 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;

        (8) the Trustee shall not be liable for any action taken, suffered, or
omitted to be taken by it in good faith and reasonably believed by it to be
authorized or within the discretion or rights or powers conferred upon it by
this Indenture; and

        (9) the Trustee shall not be deemed to have notice of any default or
Event of Default unless a responsible officer of the Trustee has actual
knowledge thereof or unless written notice of any event which is in fact such a
default is received by the Trustee at the Corporate Trust Office of the Trustee,
and such notice references the Securities and this Indenture.

SECTION 604. 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 605. MAY HOLD SECURITIES AND ACT AS TRUSTEE UNDER OTHER INDENTURES.

        The Trustee, any Authenticating Agent, any Paying Agent, any Security
Registrar or any other agent of the Company, in its individual or any other
capacity, may become the owner or

                                      -42-
<PAGE>   51

pledgee of Securities and, subject to Sections 608 and 613, may otherwise deal
with the Company with the same rights it would have if it were not Trustee,
Authenticating Agent, Paying Agent, Security Registrar or such other agent.

        Subject to the limitations imposed by the Trust Indenture Act, nothing
in this Indenture shall prohibit the Trustee from becoming and acting as trustee
under other indentures under which other securities, or certificates of interest
of participation in other securities, of the Company are outstanding in the same
manner as if it were not Trustee hereunder.

SECTION 606. 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 in writing with the Company.

SECTION 607. COMPENSATION AND REIMBURSEMENT.

        The Company agrees

        (1) to pay to the Trustee from time to time such compensation as shall
be agreed in writing between the Company and the Trustee 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.

        When the Trustee incurs expenses or renders services in connection with
an Event of Default specified in Section 501(5) or Section 501(6), the expenses
(including the reasonable charges and expenses of its counsel) and the
compensation for the services are intended to constitute expenses of
administration under any applicable Federal or State Bankruptcy, insolvency or
other similar law.

SECTION 608. 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

                                      -43-
<PAGE>   52

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.

SECTION 609. CORPORATE TRUSTEE REQUIRED; ELIGIBILITY.

        There shall at all times be one (and only one) Trustee hereunder with
respect to the Securities of each series, which may be Trustee hereunder for
Securities of one or more other series. Each Trustee shall be a Person that is
eligible pursuant to the Trust Indenture Act to act as such and has (or if the
Trustee is a member of a bank holding company system, its bank holding company
has) a combined capital and surplus of at least $50,000,000. If any 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 and to the extent permitted by the Trust Indenture Act, 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 with respect to the Securities of any
series 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 610. 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 611.

        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 611 shall
not have been delivered to the Trustee within 30 days after the giving of such
notice of resignation, the resigning Trustee may petition, at the expense of the
Company, 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 the instrument of acceptance by a successor Trustee required by
Section 611 shall not have been delivered to the Trustee within 30 days after
the giving of such notice of resignation, the resigning Trustee may petition, at
the expense of the Company, any court of competent jurisdiction for the
appointment of a successor Trustee with respect to the Securities of such
series.

        If at any time:

        (1) the Trustee shall fail to comply with Section 608 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

                                      -44-
<PAGE>   53

        (2) the Trustee shall cease to be eligible under Section 609 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 514, 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 611. 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 611, 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 611, the
retiring Trustee may petition, 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 106. 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 611. 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

                                      -45-
<PAGE>   54

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 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, upon payment
of all of its charges, 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 612. 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

                                      -46-
<PAGE>   55

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 613. 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 614. 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 306, 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 (or if the Authenticating Agent is a member of a bank holding
company system, its bank holding company has) 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 all or substantially all 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

                                      -47-

        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

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 106 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 Company agrees to pay to each Authenticating Agent from time to time
reasonable compensation for its services under this Section.

        If an appointment with respect to one or more series is made pursuant to
this Section 612, 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:

in the manner provided pursuant to the Trust Indenture Act; provided that any
such information, documents or reports required to be filed with the Commission

Trustee within 15 days after the same is so required to be filed with the
Commission.

        Delivery of such reports, information and documents to the Trustee is

SECTION 1001. PAYMENT OF PRINCIPAL, PREMIUM AND INTEREST.

        The Company covenants and agrees for the benefit of each series of
Securities that it will duly and punctually pay the principal of and any premium
and interest on the Securities of that series in accordance with the terms of
the Securities and this Indenture.

        The Company will maintain in each Place of Payment for any series of

or surrendered for payment, where Securities of that series may be surrendered
for registration of transfer or exchange, where Securities of that series may be
surrendered for conversion 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 such office or agency. If at any time the Company
shall fail to maintain any such required office or agency or shall fail to
furnish the Trustee with the address thereof, such presentations, surrenders,
notices and demands may be made or served at the Corporate Trust Office of the
Trustee, and the Company hereby appoints the Trustee as its agent to receive all
such presentations, surrenders, notices and demands.

        The Company may also from time to time designate one or more other
offices or agencies where the Securities 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 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.

SECTION 1003. MONEY FOR SECURITIES PAYMENTS TO BE HELD IN TRUST.

        If the Company shall at any time act as its own Paying Agent with

segregate and hold in trust for the benefit of the Persons entitled thereto a
sum sufficient to pay the principal and any premium and interest so becoming due
until such sums shall be paid to such Persons or otherwise disposed of as herein
provided and will promptly notify the Trustee of its action or failure so to
act.

        Whenever the Company shall have one or more Paying Agents for any series
of Securities, it will, on or 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

                                      -55-
<PAGE>   64

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) comply with the provisions of
the Trust Indenture Act applicable to it as a Paying Agent and (2) during the
continuance of any default by the Company (or any other obligor upon the
Securities of that series) in the making of any payment in respect of the
Securities of that series, upon the written request of the Trustee, forthwith
pay to the Trustee all sums held in trust by such Paying Agent for payment in
respect of the Securities of that series.

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

        Any money deposited with the Trustee or any Paying Agent, or then held
by the Company, in trust for the payment of the principal of or any premium or
interest on any Security of any series and remaining unclaimed for a period
ending on the earlier of the date that is ten Business Days prior to the date
such money would escheat to the State or two years after such principal, premium
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 shall thereafter, as an unsecured general
creditor, look only to the Company for payment thereof, and all liability of the
Trustee or such Paying Agent with respect to such trust money, and all liability
of the Company as trustee thereof, shall thereupon cease.

SECTION 1004. STATEMENT BY OFFICERS AS TO DEFAULT.

        The Company will deliver to the Trustee, within 120 days after the end
of each fiscal year of the Company ending after the date hereof, an Officers'
Certificate, stating whether or not to the best knowledge of the signers thereof
the Company is in default in the performance and observance of any of the terms,
provisions and conditions of this Indenture (without regard to any period of
grace or requirement of notice provided hereunder) and, if the Company shall be
in default, specifying all such defaults and the nature and status thereof of
which they may have knowledge. The fiscal year of the Company ends on June 30;
and the Company will give the Trustee prompt written notice of any change of its
fiscal year.

things necessary to preserve and keep in full force and effect its existence.

its business to be maintained and kept in good condition, repair and working
order and supplied with all necessary equipment and will cause to be made all
necessary repairs, renewals, replacements, betterments and improvements thereof,
all as, and to the extent, in the judgment of the Company may be necessary so
that the business carried on in connection therewith may be properly and
advantageously conducted at all times; provided, however, that nothing in this
Section shall prevent the Company from discontinuing the operation or
maintenance of any of such properties if such discontinuance is, in the judgment
of the Company, desirable in the conduct of its business and not disadvantageous
in any material respect to the Holders.

SECTION 1007. PAYMENT OF TAXES AND OTHER CLAIMS.

        The Company will pay or discharge or cause to be paid or discharged,
before the same shall become delinquent, (1) all taxes, assessments and
governmental charges levied or imposed upon the Company or upon the income,
profits or property of the Company, and (2) all lawful claims for labor,
materials and supplies which, if unpaid, might by law become a lien upon the
property of the Company; provided, however, that the Company shall not be
required to pay or discharge or cause to be paid or discharged any such tax,
assessment, charge or claim (i) whose amount, applicability or validity is being
contested in good faith by appropriate proceedings or (ii) if the failure to pay
or discharge would not have a material adverse effect on the assets, business,
operations, properties or condition (financial or otherwise) of the Company and
its subsidiaries, taken as a whole.

SECTION 1008. WAIVER OF CERTAIN COVENANTS.

        Except as otherwise specified as contemplated by Section 301 for
Securities of such series or in a supplemental indenture, 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 301(19), 901(2), 901(7), 1006 or 1007 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, 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.

SECTION 1009. CALCULATION OF ORIGINAL ISSUE DISCOUNT.

        The Company shall file with the Trustee promptly at the end of each
calendar year (i) a written notice specifying the amount of original issue
discount (including daily rates and accrual periods) accrued on Outstanding
Securities as of the end of such year and (ii) such other specific information
relating to such original issue discount as may then be relevant under the
Internal Revenue Code of 1986, as amended from time to time.

Securities to be redeemed shall be selected not more than 45 days prior to the
Redemption Date by the Trustee, from the Outstanding Securities of such series
not previously called for redemption, by lot, or in the Trustee's discretion, on
a pro-rata basis or by another method the Trustee deems fair and appropriate,
provided that the unredeemed portion of the principal amount of any Security
shall be in an authorized denomination (which shall not be less than the minimum
authorized denomination) for such Security. If less than all the Securities of
such series and of a specified tenor are to be redeemed (unless such redemption
affects only a single Security), the particular Securities to be redeemed shall
be selected not more than 45 days prior to the Redemption Date by the Trustee,
from the Outstanding Securities of such series and specified tenor not
previously called for redemption in accordance with the preceding sentence.

        If any Security selected for partial redemption is converted in part
before termination of the conversion right with respect to the portion of the
Security so selected, the converted portion of such Security shall be deemed (so
far as may be) to be the portion selected for redemption. Securities which have
been converted during a selection of Securities to be redeemed shall be treated
by the Trustee as Outstanding for the purpose of such selection.

                                      -58-
<PAGE>   67

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

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

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

SECTION 1104. NOTICE OF REDEMPTION.

        Notice of redemption shall be given by first-class mail, postage
prepaid, mailed not less than 30 nor more than 60 days prior to the Redemption
Date, unless a shorter period is specified in the Securities to be redeemed, to
each Holder of Securities to be redeemed, at its address appearing in the
Security Register.

        All notices of redemption shall identify the Securities to be redeemed
(including CUSIP number(s)) and shall state:

        (1) the Redemption Date,

        (2) the Redemption Price (including accrued interest, if any),

        (3) if less than all the Outstanding Securities of any series consisting
of more than a single Security are to be redeemed, the identification (and, in
the case of partial redemption of any such Securities, the principal amounts) of
the particular Securities to be redeemed and, if less than all the Outstanding
Securities of any series consisting of a single Security are to be redeemed, the
principal amount of the particular Security to be redeemed,

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

        (5) the place or places where each such Security is to be surrendered
for payment of the Redemption Price,

        (6) if applicable, the conversion price, that the date on which the
right to convert the principal of the Securities or the portions thereof to be
redeemed will terminate will be the Business

                                      -59-
<PAGE>   68

Day prior to the Redemption Date and the place or places where such Securities
may be surrendered for conversion, and

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

        Notice of redemption of Securities to be redeemed at the election of the
Company 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 and shall be irrevocable.

SECTION 1105. DEPOSIT OF REDEMPTION PRICE.

        On or prior to 10:00 a.m., New York time, on 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 1003) an amount of money sufficient to pay the Redemption
Price of, and (except if the Redemption Date shall be an Interest Payment Date)
accrued interest on, all the Securities which are to be redeemed on that date.

        If any Security called for redemption is converted, any money deposited
with the Trustee or with a Paying Agent or so segregated and held in trust for
the redemption of such Security shall (subject to the right of any Holder of
such Security to receive interest as provided in the last paragraph of Section
307) be paid to the Company on Company Request, or if then held by the Company,
shall be discharged from such trust.

SECTION 1106. 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. Upon surrender of any
such Security 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, unless otherwise specified as
contemplated by Section 301, installments of interest whose Stated Maturity is
on or prior to the Redemption Date will 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 Record Dates according to their terms and the
provisions of Section 307.

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

SECTION 1107. SECURITIES REDEEMED IN PART.

        Any Security which is to be redeemed only in part shall be surrendered
at a Place of Payment therefor (with, if the Company or the Trustee so requires,
due endorsement by, or a written instrument of transfer in form satisfactory to
the Company and the Trustee duly executed by, the

                                      -60-
<PAGE>   69

Holder thereof or its attorney duly authorized in writing), and the Company
shall execute, and the Trustee shall authenticate and deliver to the Holder of
such Security without service charge to such Holder, a new Security or
Securities of the same series and of like tenor, of any authorized denomination
as requested by such Holder, in aggregate principal amount equal to and in
exchange for the unredeemed portion of the principal of the Security so
surrendered.

                                 ARTICLE TWELVE

                                  SINKING FUNDS

SECTION 1201. APPLICABILITY OF ARTICLE.

        The provisions of this Article shall be applicable to any sinking fund
for the retirement of Securities of any series except as otherwise specified as
contemplated by Section 301 for such Securities.

        The minimum amount of any sinking fund payment provided for by the terms
of any Securities 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
such Securities is herein referred to as an "optional sinking fund payment." If
provided for by the terms of any Securities, the cash amount of any sinking fund
payment may be subject to reduction as provided in Section 1202. Each sinking
fund payment shall be applied to the redemption of Securities as provided for by
the terms of such Securities.

SECTION 1202. SATISFACTION OF SINKING FUND PAYMENTS WITH SECURITIES.

        The Company (1) may deliver Outstanding Securities of a series (other
than any previously called for redemption) and (2) may apply as a credit
Securities of a series which have been 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, in each case in satisfaction of all or any part of any sinking fund
payment with respect to any Securities of such series required to be made
pursuant to the terms of such Securities as and to the extent provided for by
the terms of such Securities; provided that the Securities to be so credited
have not been previously so credited. The Securities to be so credited shall be
received and credited for such purpose by the Trustee at the Redemption Price,
as specified in the Securities so to be redeemed, for redemption through
operation of the sinking fund and the amount of such sinking fund payment shall
be reduced accordingly.

SECTION 1203. REDEMPTION OF SECURITIES FOR SINKING FUND.

        Not less than 60 days prior to each sinking fund payment date for any
Securities, the Company will deliver to the Trustee an Officers' Certificate
specifying the amount of the next ensuing sinking fund payment for such
Securities pursuant to the terms of such Securities, 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 pursuant to
Section 1202 and will also

                                      -61-
<PAGE>   70

deliver to the Trustee any Securities to be so delivered. Not less than 30 days
prior to 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 1103 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 1104. Such notice having been duly given, the redemption of such
Securities shall be made upon the terms and in the manner stated in Sections
1106 and 1107.

                                ARTICLE THIRTEEN

                       DEFEASANCE AND COVENANT DEFEASANCE

SECTION 1301. COMPANY'S OPTION TO EFFECT DEFEASANCE OR COVENANT DEFEASANCE.

        The Company may elect, at its option at any time, to have Section 1302
or Section 1303 applied to any Securities or any series of Securities, as the
case may be, designated pursuant to Section 301 as being defeasible pursuant to
such Section 1302 or 1303, in accordance with any applicable requirements
provided pursuant to Section 301 and upon compliance with the conditions set
forth below in this Article. Any such election shall be evidenced by a Board
Resolution or in another manner specified as contemplated by Section 301 for
such Securities.

SECTION 1302. DEFEASANCE AND DISCHARGE.

        Upon the Company's exercise of its option (if any) to have this Section
applied to any Securities or any series of Securities, as the case may be, the
Company shall be deemed to have been discharged from its obligations, and the
provisions of Article Fifteen shall cease to be effective, with respect to such
Securities as provided in this Section on and after the date the conditions set
forth in Section 1304 are satisfied (hereinafter called "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 to have
satisfied all its other obligations under such Securities and this Indenture
insofar as such Securities are concerned (and the Trustee, at the expense of the
Company, shall execute proper instruments acknowledging the same), subject to
the following which shall survive until otherwise terminated or discharged
hereunder: (1) the rights of Holders of such Securities to receive, solely from
the trust fund described in Section 1304 and as more fully set forth in such
Section, payments in respect of the principal of and any premium and interest on
such Securities when payments are due, (2) the Company's obligations with
respect to such Securities under Sections 304, 305, 306, 1002 and 1003, and, if
applicable, Article Fourteen, (3) the rights, powers, trusts, duties and
immunities of the Trustee hereunder and (4) this Article. Subject to compliance
with this Article, the Company may exercise its option (if any) to have this
Section applied to any Securities notwithstanding the prior exercise of its
option (if any) to have Section 1303 applied to such Securities.

SECTION 1301. COVENANT DEFEASANCE.

        Upon the Company's exercise of its option (if any) to have this Section
applied to any Securities or any series of Securities, as the case may be, (1)
the Company shall be released from its

                                      -62-
<PAGE>   71

obligations under Sections 1006 through 1007, inclusive, and any covenants
provided pursuant to Section 301(19), 901(2) or 901(7) for the benefit of the
Holders of such Securities and (2) the occurrence of any event specified in
Sections 501(4) (with respect to any of Sections 1006 through 1007, inclusive,
and any such covenants provided pursuant to Section 301(19), 901(2) or 901(7)),
shall be deemed not to be or result in an Event of Default, and (3) the
provisions of Article Fifteen shall cease to be effective, in each case with
respect to such Securities as provided in this Section on and after the date the
conditions set forth in Section 1304 are satisfied (hereinafter called "Covenant
Defeasance"). For this purpose, such Covenant Defeasance means that, with
respect to such Securities, 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 specified Section (to the extent so specified in the case of Section
501(4)) or Article Fifteen, whether directly or indirectly by reason of any
reference elsewhere herein to any such Section or Article or by reason of any
reference in any such Section or Article to any other provision herein or in any
other document, but the remainder of this Indenture and such Securities shall be
unaffected thereby.

SECTION 1304. CONDITIONS TO DEFEASANCE OR COVENANT DEFEASANCE.

        The following shall be the conditions to the application of Section 1302
or Section 1303 to any Securities or any series of Securities, as the case may
be:

        (1) The Company shall irrevocably have deposited or caused to be
deposited with the Trustee (or another trustee which satisfies the requirements
contemplated by Section 609 and agrees to comply with the provisions of this
Article applicable to it) as trust funds in trust for the purpose of making the
following payments, specifically pledged as security for, and dedicated solely
to, the benefits of the Holders of such Securities, (A) money in an amount, or
(B) U.S. Government Obligations which through the scheduled payment of principal
and interest in respect thereof in accordance with their terms will provide, not
later than one day before the due date of any payment, money in an amount, or
(C) a combination thereof, in each case sufficient, in the opinion of a
nationally recognized firm of independent public accountants expressed in a
written certification thereof delivered to the Trustee, to pay and discharge,
and which shall be applied by the Trustee (or any such other qualifying trustee)
to pay and discharge, the principal of and any premium and interest on such
Securities on the respective Stated Maturities, in accordance with the terms of
this Indenture and such Securities. As used herein, "U.S. Government Obligation"
means (x) any security which is (i) a direct obligation of the United States of
America for the payment of which the full faith and credit of the United States
of America is pledged or (ii) an obligation of a Person controlled or supervised
by and acting as an agency or instrumentality of the United States of America
the payment of which is unconditionally guaranteed as a full faith and credit
obligation by the United States of America, which, in either case (i) or (ii),
is not callable or redeemable at the option of the issuer thereof, and (y) any
depositary receipt issued by a bank (as defined in Section 3(a)(2) of the
Securities Act) as custodian with respect to any U.S. Government Obligation
which is specified in Clause (x) above and held by such bank for the account of
the holder of such depositary receipt, or with respect to any specific payment
of principal of or interest on any U.S. Government Obligation which is so
specified and held, provided that (except as required by law) such custodian is
not authorized to make any deduction from the amount payable to the holder of

                                      -63-
<PAGE>   72

such depositary receipt from any amount received by the custodian in respect of
the U.S. Government Obligation or the specific payment of principal or interest
evidenced by such depositary receipt.

        (2) In the event of an election to have Section 1302 apply to any
Securities or any series of Securities, as the case may be, the Company shall
have delivered to the Trustee an Opinion of Counsel stating that (A) the Company
has received from, or there has been published by, the Internal Revenue Service
a ruling or (B) since the date of this instrument, there has been a change in
the applicable Federal income tax law, in either case (A) or (B) to the effect
that, and based thereon such opinion shall confirm that, the Holders of such
Securities will not recognize gain or loss for Federal income tax purposes as a
result of the deposit, Defeasance and discharge to be effected with respect to
such Securities and will be subject to Federal income tax on the same amount, in
the same manner and at the same times as would be the case if such deposit,
Defeasance and discharge were not to occur.

        (3) In the event of an election to have Section 1303 apply to any
Securities or any series of Securities, as the case may be, the Company shall
have delivered to the Trustee an Opinion of Counsel to the effect that the
Holders of such Securities will not recognize gain or loss for Federal income
tax purposes as a result of the deposit and Covenant Defeasance to be effected
with respect to such Securities and will be subject to Federal income tax on the
same amount, in the same manner and at the same times as would be the case if
such deposit and Covenant Defeasance were not to occur.

        (4) The Company shall have delivered to the Trustee an Officers'
Certificate to the effect that neither such Securities nor any other Securities
of the same series, if then listed on any securities exchange, will be delisted
as a result of such deposit.

        (5) No event which is, or after notice or lapse of time or both would
become, an Event of Default with respect to such Securities or any other
Securities shall have occurred and be continuing at the time of such deposit or,
with regard to any such event specified in Sections 501(5) and (6), at any time
on or prior to the 90th day after the date of such deposit (it being understood
that this condition shall not be deemed satisfied until after such 90th day).

        (6) Such Defeasance or Covenant Defeasance shall not cause the Trustee
to have a conflicting interest within the meaning of the Trust Indenture Act
(assuming all Securities are in default within the meaning of such Act).

        (7) Such Defeasance or Covenant Defeasance shall not result in a breach
or violation of, or constitute a default under, any other agreement or
instrument to which the Company is a party or by which it is bound.

        (8) Such Defeasance or Covenant Defeasance shall not result in the trust
arising from such deposit constituting an investment company within the meaning
of the Investment Company Act unless such trust shall be registered under such
Act or exempt from registration thereunder.

                                      -64-
<PAGE>   73

        (9) At the time of such deposit, (A) no default in the payment of any
principal of or premium or interest on any Senior Indebtedness shall have
occurred and be continuing, (B) no event of default with respect to any Senior
Indebtedness shall have resulted in such Senior Indebtedness becoming, and
continuing to be, due and payable prior to the date on which it would otherwise
have become due and payable (unless payment of such Senior Indebtedness has been
made or duly provided for), and (C) no other event of default with respect to
any Senior Indebtedness shall have occurred and be continuing permitting (after
notice or lapse of time or both) the holders of such Senior Indebtedness (or a
trustee on behalf of such holders) to declare such Senior Indebtedness due and
payable prior to the date on which it would otherwise have become due and
payable.

        (10) The Company shall have delivered to the Trustee an Officers'
Certificate and an Opinion of Counsel, each stating that all conditions
precedent with respect to such Defeasance or Covenant Defeasance have been
complied with.

SECTION 1305. DEPOSITED MONEY AND U.S. GOVERNMENT OBLIGATIONS TO BE HELD IN
              TRUST; MISCELLANEOUS PROVISIONS.

        Subject to the provisions of the last paragraph of Section 1003, all
money and U.S. Government Obligations (including the proceeds thereof) deposited
with the Trustee or other qualifying trustee (solely for purposes of this
Section and Section 1306, the Trustee and any such other trustee are referred to
collectively as the "Trustee") pursuant to Section 1304 in respect of any
Securities shall be held in trust and applied by the Trustee, in accordance with
the provisions of such Securities and this Indenture, to the payment, either
directly or through any such Paying Agent (including the Company acting as its
own Paying Agent) as the Trustee may determine, to the Holders of such
Securities, of all sums due and to become due thereon in respect of principal
and any premium and interest, but money so held in trust need not be segregated
from other funds except to the extent required by law. Money and U.S. Government
Obligations so held in trust shall not be subject to the provisions of Article
Fifteen.

        The Company shall pay and indemnify the Trustee against any tax, fee or
other charge imposed on or assessed against the U.S. Government Obligations
deposited pursuant to Section 1304 or the principal and interest received in
respect thereof other than any such tax, fee or other charge which by law is for
the account of the Holders of Outstanding Securities.

        Anything in this Article to the contrary notwithstanding, the Trustee
shall deliver or pay to the Company from time to time upon Company Request any
money or U.S. Government Obligations held by it as provided in Section 1304 with
respect to any Securities which, in the opinion of a nationally recognized firm
of independent public accountants expressed in a written certification thereof
delivered to the Trustee, are in excess of the amount thereof which would then
be required to be deposited to effect the Defeasance or Covenant Defeasance, as
the case may be, with respect to such Securities.

                                      -65-
<PAGE>   74

SECTION 1306. REINSTATEMENT.

        If the Trustee or the Paying Agent is unable to apply any money in
accordance with this Article with respect to any Securities by reason of any
order or judgment of any court or governmental authority enjoining, restraining
or otherwise prohibiting such application, then the obligations under this
Indenture and such Securities from which the Company has been discharged or
released pursuant to Section 1302 or 1303 shall be revived and reinstated as
though no deposit had occurred pursuant to this Article with respect to such
Securities, until such time as the Trustee or Paying Agent is permitted to apply
all money held in trust pursuant to Section 1305 with respect to such Securities
in accordance with this Article; provided, however, that if the Company makes
any payment of principal of or any premium or interest on any such Security
following such reinstatement of its obligations, the Company shall be subrogated
to the rights (if any) of the Holders of such Securities to receive such payment
from the money so held in trust.

                                ARTICLE FOURTEEN

                      CONVERSION AND EXCHANGE OF SECURITIES

SECTION 1401. APPLICABILITY OF ARTICLE.

        The provisions of this Article shall be applicable to the Securities of
any series which are convertible or exchangeable into shares of Common Stock of
the Company, and the issuance of such shares of Common Stock upon the conversion
of such Securities, except as otherwise specified as contemplated by Section 301
for the Securities of such series.

SECTION 1402. EXERCISE OF CONVERSION AND EXCHANGE PRIVILEGE.

        In order to exercise a conversion or exchange privilege, the Holder of a
Security of a series with such a privilege shall surrender such Security to the
Company at the office or agency maintained for that purpose pursuant to Section
1002, accompanied by a duly executed conversion or exchange notice to the
Company substantially in the form set forth in Section 206 stating 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 shares of Common Stock which shall be issuable on such
conversion or exchange shall be issued. 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; and Securities so surrendered for conversion or
exchange (in whole or in part) during the period from the close of business on
any Regular Record Date to the opening of business on the next succeeding
Interest Payment Date (excluding Securities or portions thereof called for
redemption during the period beginning at the close of business on a Regular
Record Date and ending at the opening of business on the first Business Day
after the next succeeding Interest Payment Date, or if such Interest Payment
Date is not a Business Day, the second such Business Day) shall also be
accompanied by payment in funds acceptable to the

                                      -66-
<PAGE>   75

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 notwithstanding the
conversion or exchange of such Security, subject to the provisions of Section
307 relating to the payment of Defaulted Interest by the Company. As promptly as
practicable after the receipt of such notice and of any payment required
pursuant to a Board Resolution and, subject to Section 303, 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 full shares of Common Stock 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 Common Stock otherwise issuable upon such conversion or exchange. 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 (unless
such Holder shall have so surrendered such Security and shall have instructed
the Company to effect the conversion or exchange on a particular date following
such surrender and such Holder shall be entitled to convert or exchange such
Security on such date, in which case such conversion or exchange shall be deemed
to be effected immediately prior to the close of business on such date) 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 shares of Common Stock 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 shares represented thereby. Except as set forth above and
subject to the final paragraph of Section 307, no payment or adjustment shall be
made upon any conversion or exchange on account of any interest accrued on the
Securities (or any part thereof) surrendered for conversion or exchange or on
account of any dividends on the Common Stock of the Company issued upon such
conversion or exchange.

        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 1403. NO FRACTIONAL SHARES.

        No fractional share of Common Stock 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 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

                                      -67-
<PAGE>   76

the provisions of this Section 1403, any Holder of a Security or Securities
would be entitled to a fractional share of Common Stock 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 Common Stock
is listed or admitted to unlisted trading privileges on a national securities
exchange or market, on the basis of the last reported sale price regular way on
such exchange or market on the last trading day prior to the date of conversion
or exchange upon which such a sale shall have been effected, or (ii) if such
Common Stock is not at the time so listed or admitted to unlisted trading
privileges on a national securities exchange or market, on the basis of the
average of the bid and asked prices of such Common Stock 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 if not so available, the fair market price as determined by the
Board of Directors. For purposes of this Section, "trading day" shall mean each
Monday, Tuesday, Wednesday, Thursday and Friday other than any day on which the
Common Stock is not traded on the Nasdaq National Market, or if the Common Stock
is not traded on the Nasdaq National Market, on the principal exchange or market
on which the Common Stock is traded or quoted.

SECTION 1404. ADJUSTMENT OF CONVERSION AND EXCHANGE PRICE.

        The conversion price of Securities of any series that is convertible or
exchangeable into Common Stock of the Company shall be adjusted for any stock
dividends, stock splits, reclassifications, combinations or similar transactions
in accordance with the terms of the supplemental indenture or Board Resolutions
setting forth 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 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,
and such certificate shall forthwith be filed at each office or agency
maintained for the purpose of conversion or exchange of Securities pursuant to
Section 1002 and, if different, with the Trustee. The Company shall forthwith
cause a notice setting forth the adjusted conversion or exchange price to be
mailed, first class postage prepaid, to each Holder of Securities of such series
at its address appearing on the Security Register and to any conversion or
exchange agent other than the Trustee.

SECTION 1405. NOTICE OF CERTAIN CORPORATE ACTIONS.

        In case:

        (1) the Company shall declare a dividend (or any other distribution) on
its Common Stock payable otherwise than in cash out of its retained earnings
(other than a dividend for which approval of any shareholders of the Company is
required) that would require an adjustment pursuant to Section 1404; or

                                      -68-
<PAGE>   77

        (2) the Company shall authorize the granting to all or substantially all
of the holders of its Common Stock 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 shareholders of the Company
is required); or

        (3) of any reclassification of the Common Stock of the Company (other
than a subdivision or combination of its outstanding shares of Common Stock, or
of any consolidation, merger or share exchange to which the Company is a party
and for which approval of any shareholders of the Company is required), or of
the sale of all or substantially all of the assets of the Company; or

        (4) 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 last addresses as they shall appear in the
Security Register, at least 20 days (or 10 days in any case specified in Clause
(1) or (2) 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 Common Stock 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
Common Stock of record shall be entitled to exchange their shares of Common
Stock 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 1406. RESERVATION OF SHARES OF COMMON STOCK.

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

SECTION 1407. PAYMENT OF CERTAIN TAXES UPON CONVERSION AND EXCHANGE.

Except as provided in the next sentence, the Company will pay any and all taxes
that may be payable in respect of the issue or delivery of shares of its Common
Stock 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 shares of its Common Stock 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

                                      -69-
<PAGE>   78

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 1408. NONASSESSABILITY.

        The Company covenants that all shares of its Common Stock which may be
issued upon conversion or exchange of Securities will upon issue in accordance
with the terms hereof be duly and validly issued and fully paid and
nonassessable.

SECTION 1409. PROVISION IN CASE OF CONSOLIDATION, MERGER OR SALE OF ASSETS.

        In case of any consolidation or merger of the Company with or into any
other Person, any merger of another Person with or into the Company (other than
a merger which does not result in any reclassification, conversion, exchange or
cancellation of outstanding shares of Common Stock of the Company) or any
conveyance, sale, transfer or lease of all or substantially all of the assets of
the Company, the Person formed by such consolidation or resulting from such
merger or which acquires such assets, as the case may be, shall execute and
deliver to the Trustee a supplemental indenture providing that the Holder of
each Security of a series then Outstanding that is convertible or exchangeable
into Common Stock of the Company shall have the right thereafter (which right
shall be the exclusive conversion right thereafter available to said Holder),
during the period such Security shall be convertible or exchangeable, to convert
or exchange such Security only into the kind and amount of securities, cash and
other property receivable upon such consolidation, merger, conveyance, sale,
transfer or lease by a holder of the number of shares of Common Stock of the
Company into which such Security might have been converted or exchanged
immediately prior to such consolidation, merger, conveyance, sale, transfer or
lease, assuming such holder of Common Stock of the Company (i) is not a Person
with which the Company consolidated or merged with or into or which merged into
or with the Company or to which such conveyance, sale, transfer or lease was
made, as the case may be (a "Constituent Person"), or an Affiliate of a
Constituent Person and (ii) failed to exercise his rights of election, if any,
as to the kind or amount of securities, cash and other property receivable upon
such consolidation, merger, conveyance, sale, transfer or lease (provided that
if the kind or amount of securities, cash and other property receivable upon
such consolidation, merger, conveyance, sale, transfer, or lease is not the same
for each share of Common Stock of the Company held immediately prior to such
consolidation, merger, conveyance, sale, transfer or lease by others than a
Constituent Person or an Affiliate thereof and in respect of which such rights
of election shall not have been exercised ("Non-electing Share"), then for the
purpose of this Section 1409 the kind and amount of securities, cash and other
property receivable upon such consolidation, merger, conveyance, sale, transfer
or lease by the holders of each Non-electing Share shall be deemed to be the
kind and amount so receivable per share by a plurality of the Non-electing
Shares). Such supplemental indenture shall provide for adjustments which, for
events subsequent to the effective date of such supplemental indenture, shall be
as nearly equivalent as may be practicable to the adjustments provided for in
this Article or in accordance with the terms of the supplemental indenture or
Board Resolutions setting forth the terms of such adjustments. The above
provisions of this Section 1409 shall similarly apply to successive
consolidations, mergers, conveyances, sales, transfers or leases. Notice of the
execution of such a supplemental indenture shall be given by the

                                      -70-
<PAGE>   79

Company to the Holder of each Security of a series that is convertible or
exchangeable into Common Stock of the Company as provided in Section 106
promptly upon such execution.

        Neither the Trustee nor any conversion or exchange agent, if any, shall
be under any responsibility to determine the correctness of any provisions
contained in any such supplemental indenture relating either to the kind or
amount of shares of stock or other securities or property or cash receivable by
Holders of Securities of a series convertible or exchangeable into Common Stock
of the Company upon the conversion or exchange of their Securities after any
such consolidation, merger, conveyance, transfer, sale or lease or to any such
adjustment, but may accept as conclusive evidence of the correctness of any such
provisions, and shall be protected in relying upon, an Opinion of Counsel with
respect thereto, which the Company shall cause to be furnished to the Trustee
upon request.

SECTION 1410. DUTIES OF TRUSTEE REGARDING CONVERSION AND EXCHANGE.

        Neither the Trustee nor any conversion 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 Common Stock 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 (or whether any provisions of any supplemental indenture
are correct), 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 shares of Common Stock 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 601, neither the Trustee nor any conversion or exchange agent shall be
responsible for any failure of the Company to issue, transfer or deliver any
shares of its Common Stock or stock certificates or other securities or property
upon the surrender of any Security for the purpose of conversion or to comply
with any of the covenants of the Company contained in this Article Fourteen 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 1411. REPAYMENT OF CERTAIN FUNDS UPON CONVERSION AND EXCHANGE.

        Any funds which at any time shall have been deposited by the Company or
on its behalf with the Trustee or any other paying agent for the purpose of
paying the principal of, and premium, if any, and interest, if any, on any of
the Securities (including, but not limited to, funds deposited for the sinking
fund referred to in Article Twelve hereof and funds deposited pursuant to
Article Thirteen hereof) and which shall not be required for such purposes
because of the conversion or exchange of such Securities as provided in this
Article Fourteen shall after such conversion or exchange be repaid to the
Company by the Trustee upon the Company's written request.

                                 ARTICLE FIFTEEN

                           SUBORDINATION OF SECURITIES

SECTION 1501. SECURITIES SUBORDINATED TO SENIOR INDEBTEDNESS.

        Except as otherwise provided in a supplemental indenture or pursuant to
Section 301, the Company covenants and agrees, and each Holder of a Security, by
his acceptance thereof, likewise covenants and agrees, that the indebtedness
represented by the Securities and the payment of the principal of (and premium,
if any) and interest on each and all of the Securities is hereby expressly
subordinate and junior, to the extent and in the manner hereinafter set forth,
in right of payment to the prior payment in full of all Senior Indebtedness.

        (1) In the event of any distribution of assets of the Company upon any
dissolution, winding up, liquidation or reorganization of the Company, whether
in bankruptcy, insolvency, reorganization or receivership proceedings or upon an
assignment for the benefit of creditors or any other marshaling of the assets
and liabilities of the Company or otherwise, then the holders of all Senior
Indebtedness shall first be entitled to receive payment of the full amount due
thereon in cash or other consideration satisfactory to the holders of Senior
Indebtedness in respect of principal (and premium, if any) and interest, or
provision shall be made for such amount in cash or other consideration
satisfactory to the holders of Senior Indebtedness, before the Holders of any of
the Securities are entitled to receive any payment or distribution of any
character, whether in cash, securities or other property, on account of the
principal of (or premium, if any) or interest on the indebtedness evidenced by
the Securities.

        For purposes of this Article Fifteen, the words, "cash, securities or
other property" shall not be deemed to include shares of stock of the Company as
reorganized or readjusted, or securities of the Company or any other corporation
provided for by a plan of reorganization or readjustment, the payment of which
is subordinated at least to the extent provided in this Article Fifteen with
respect to the Securities to the payment of all Senior Indebtedness which may at
the time be outstanding; provided that (i) the Senior Indebtedness is assumed by
the new corporation, if any, resulting from any reorganization or readjustment,
and (ii) the rights of the holders of Senior Indebtedness (other than leases
which are not assumed by the Company or the new corporation, as the case may be)
are not, without the consent of such holders, altered by such reorganization or
readjustment. The consolidation of the Company with, or the merger of the
Company into, another person or the liquidation or dissolution of the Company
following the conveyance or transfer of its property as an entirety, or
substantially as an entirety, to another person upon the terms and conditions
provided for in Article Eight shall not be deemed a dissolution, winding-up,
liquidation or reorganization for the purposes of this Section 1501(1) if such
other person shall, as a part of such consolidation, merger, conveyance or
transfer, comply with the conditions stated in Article Eight.

        (2) In the event of any default in payment of the principal of or
premium, if any, or interest on, rent under, or any other payment obligation
under any Senior Indebtedness (a "Payment Default") beyond any applicable grace
period with respect thereto, then, unless and until all such payments due in
respect of such Senior Indebtedness have been paid in full in cash or other

                                      -72-
<PAGE>   81

consideration satisfactory to holders of Senior Indebtedness or such default
shall have been cured or waived or shall have ceased to exist, no payment shall
be made by the Company with respect to the principal of, premium, if any, or
interest on the Securities or to acquire any of the Securities.

        (3) In the event (i) any event of default, other than a Payment Default,
with respect to any Designated Senior Indebtedness shall have occurred and be
continuing permitting the holders of such Designated Senior Indebtedness (or a
trustee or other representative on behalf of the holders thereof) to declare
such Designated Senior Indebtedness due and payable prior to the date on which
it would otherwise have become due and payable, upon written notice thereof to
the Company and the Trustee by any holders of such Designated Senior
Indebtedness (or a trustee or other representative on behalf of the holders
thereof) (the "Default Notice"), unless and until such event of default shall
have been cured or waived or shall have ceased to exist and such acceleration
shall have been rescinded or annulled, or (ii) any judicial proceeding shall be
pending with respect to any such default in payment or event of default, then no
payment shall be made by the Company, directly or indirectly, with respect to
principal of, premium, if any, or interest on the Securities; provided, however,
that clause (i) of this paragraph shall not prevent the making of any such
payment by the Company with respect to the Securities for more than 179 days
after a Default Notice shall have been received by the Trustee unless the
Designated Senior Indebtedness in respect of which such event of default exists
has been declared due and payable in its entirety in which case no such payment
may be made until such acceleration has been rescinded or annulled or such
Designated Senior Indebtedness has been paid in full. Notwithstanding the
foregoing, no event of default which existed or was continuing on the date of
any Default Notice shall be made the basis for the giving of a second Default
Notice; provided, further, however, that no subsequent Default Notice shall be
effective for purposes of this Section 1501(3) unless and until at least 365
days shall have elapsed since the initial effectiveness of the immediately prior
Default Notice.

        (4) If the maturity of the Securities is accelerated, no payment may be
made on the Securities until all amounts due or to become due on Senior
Indebtedness has been paid in full in cash or other consideration satisfactory
to holders of Senior Indebtedness or until such acceleration has been cured or
waived.

        (5) In the event that, notwithstanding the foregoing provisions of
Sections 1501(1), (2), (3) and (4), any payment on account of principal of or
interest on the Securities shall be made by or on behalf of the Company and
received by the Trustee, by any Holder or by any Paying Agent (or, if the
Company is acting as its own Paying Agent, money for any such payment shall be
segregated and held in trust), at a time when such payment is not permitted by
any of such provisions, then, unless and until all Senior Indebtedness (or
Designated Senior Indebtedness, in the case of Section 1051(3)) is paid in full
in cash or other consideration satisfactory to the holders thereof, or such
payment is otherwise permitted to be made by the provisions of each of Sections
1501(1), 1501(2), 1501(3) and 1501(4) (subject, in each case, to the provisions
of Section 1507), such payment on account of principal of or interest on the
Securities shall be held in trust for the benefit of, and shall be immediately
paid over to, the holders of Senior Indebtedness (or Designated Senior
Indebtedness, in the case of Section 1501(3)) or their representative or
representatives or the trustee or trustees under any indenture under which any
instruments evidencing any of the Senior Indebtedness (or

                                      -73-
<PAGE>   82

Designated Senior Indebtedness, in the case of Section 1501(3)) may have been
issued, as their interests may appear.

        Regardless of anything to the contrary herein, nothing shall prevent (a)
any payment by the Company or the Trustee to Holders of amounts in connection
with a redemption of Securities if (i) notice of such redemption has been given
pursuant to Section 1102 prior to the receipt by the Trustee of written notice
as aforesaid, and (ii) such notice of redemption is given not earlier than 75
days before the Redemption Date, or (b) any payment by the Trustee to the
Holders of amounts deposited with it pursuant to Sections 1501 and 1502.

SECTION 1502. SUBROGATION.

        Subject to the payment in full of all Senior Indebtedness to which the
indebtedness evidenced by the Securities is in the circumstances subordinated as
provided in Section 1501, the Holders of the Securities (together with the
holders of any other indebtedness of the Company which is subordinate in right
of payment to the payment in full of all Senior Indebtedness, which is not
subordinate in right of payment to the Securities and which by its terms grants
such right of subrogation to the holders thereof) shall be subrogated to the
rights of the holders of such Senior Indebtedness to receive payments or
distributions of cash, property or securities of the Company applicable to such
Senior Indebtedness until all amounts owing on the Securities shall be paid in
full, and, as between the Company, its creditors other than holders of such
Senior Indebtedness, and the Holders of the Securities, no such payment or
distribution made to the holders of Senior Indebtedness by virtue of this
Article which otherwise would have been made to the Holders of the Securities
shall be deemed to be a payment by the Company on account of such Senior
Indebtedness, it being understood that the provisions of this Article are and
are intended solely for the purpose of defining the relative rights of the
Holders of the Securities, on the one hand, and the holders of Senior
Indebtedness, on the other hand.

SECTION 1503. OBLIGATION OF COMPANY UNCONDITIONAL.

        Nothing contained in this Article or elsewhere in this Indenture or in
the Securities is intended to or shall impair, as between the Company, its
creditors other than the holders of Senior Indebtedness, and the Holders of the
Securities, the obligation of the Company, which is absolute and unconditional,
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 is intended to or shall affect the relative
rights of the Holders of the Securities and creditors of the Company other than
the holders of Senior Indebtedness, nor shall anything herein or therein 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 Indebtedness in
respect of cash, property or securities of the Company received upon the
exercise of any such remedy.

                                      -74-
<PAGE>   83

SECTION 1504. MODIFICATION OF TERMS OF SENIOR INDEBTEDNESS.

        Any renewal or extension of the time of payment of any Senior
Indebtedness or the exercise by the holders of Senior Indebtedness of any of
their rights under any instrument creating or evidencing Senior Indebtedness,
including without limitation the waiver of default thereunder, may be made or
done all without notice to or assent from the Holders of the Securities or the
Trustee.

        No compromise, alteration, amendment, modification, extension, renewal
or other change of, or waiver, consent or other action in respect of, any
liability or obligation under or in respect of, or of any of the terms,
covenants or conditions of any indenture or other instrument under which any
Senior Indebtedness is outstanding or of such Senior Indebtedness, whether or
not such release is in accordance with the provisions of any applicable
document, shall in any way alter or affect any of the provisions of this Article
or of the Securities relating to the subordination thereof.

SECTION 1505. PAYMENTS ON SECURITIES PERMITTED.

        Nothing contained in this Article or elsewhere in this Indenture, or in
any of the Securities, shall affect the obligation of the Company to make, or
prevent the Company from making, payments of the principal of, or premium, if
any, or interest on the Securities in accordance with the provisions hereof and
thereof, or shall prevent the Trustee or any Paying Agent from applying any
moneys deposited with it hereunder to the payment of the principal of, or
premium, if any, or interest on the Securities, in each case except as otherwise
provided in this Article.

SECTION 1506. EFFECTUATION OF SUBORDINATION BY TRUSTEE.

        Each Holder of Securities, by his acceptance thereof, authorizes and
directs the Trustee in his or her behalf to take such action as may be necessary
or appropriate to effectuate the subordination provided in this Article and
appoints the Trustee his or attorney-in-fact for any and all such purposes.

        Upon any payment or distribution of assets of the Company referred to in
this Article, the Trustee and the Holders of the Securities shall be entitled to
rely upon any order or decree made by any court of competent jurisdiction in
which any such dissolution, winding up, liquidation or reorganization proceeding
affecting the affairs of the Company is pending or upon a certificate of the
trustee in bankruptcy, receiver, assignee for the benefit of creditors,
liquidating trustee or agent or other Person making any payment or distribution,
delivered to the Trustee or to the Holders of the Securities, for the purpose of
ascertaining the Persons entitled to participate in such payment or
distribution, and as to other facts pertinent to the right of such Persons under
this Article, and if such evidence is not furnished, the Trustee may defer any
payment to such Persons pending judicial determination as to the right of such
Persons to receive such payment.

SECTION 1507. KNOWLEDGE OF TRUSTEE.

        Notwithstanding the provisions of this Article or any other provisions
of this Indenture, the Trustee shall not be charged with knowledge of the
existence of any Senior Indebtedness, of any

                                      -75-
<PAGE>   84

default in payment of principal, premium (if any) or interest on any Senior
Indebtedness, or of any facts which would prohibit the making of any payment of
moneys to or by the Trustee, or the taking of any other action by the Trustee,
unless and until a Responsible Officer of the Trustee having responsibility for
the administration of the trust established by this Indenture shall have
received written notice thereof from the Company, any Holder of Securities, any
Paying or Conversion Agent of the Company or the holder or representative of any
class of Senior Indebtedness, and, prior to the receipt of any such written
notice, the Trustee shall be entitled in all respects to assume that no such
default or facts exist; provided, however, that unless on the third Business Day
prior to the date upon which by the terms hereof any such moneys may become
payable for any purpose (other than a payment under Article Eleven) the Trustee
shall have received the notice provided for in this Section 1507, then, anything
herein contained to the contrary notwithstanding, the Trustee shall have full
power and authority to receive such moneys and apply the same to the purpose for
which they were received, and shall not be affected by any notice to the
contrary which may be received by it on or after such date.

SECTION 1508. TRUSTEE'S RELATION TO SENIOR INDEBTEDNESS.

        The Trustee shall be entitled to all the rights set forth in this
Article with respect to any Senior Indebtedness at the time held by it, to the
same extent as any other holder of Senior Indebtedness and nothing in this
Indenture shall deprive the Trustee of any of its rights as such holder.

        Nothing in this Article shall apply to claims of or payments to the
Trustee under or pursuant to Section 607.

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

SECTION 1509. RIGHTS OF HOLDERS OF SENIOR INDEBTEDNESS NOT IMPAIRED.

        No right of any present or future holder of any Senior Indebtedness to
enforce the subordination herein shall at any time or in any way be prejudiced
or impaired by any act or failure to act on the part of the Company 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.

SECTION 1510. CERTAIN CONVERSIONS NOT DEEMED PAYMENT.

        For the purposes of this Article Fifteen only, (1) the issuance and
delivery of junior securities upon conversion of Securities in accordance with
Article Fourteen shall not be deemed to constitute a payment or distribution on
account of the principal of, premium, if any, or interest on Securities or on
account of the purchase or other acquisition of Securities, and (2) the payment,
issuance or delivery of cash (except in satisfaction of fractional shares
pursuant to Section 1403), property or securities (other than junior securities)
upon conversion of a Security shall be deemed to constitute payment on account
of the principal of, premium, if any, or interest on such Security. For the
purposes of this Section 1510, the term "junior securities" means (a) shares of
any stock of any class of the Company or (b) securities of the Company that are
subordinated in right of payment to all Senior Indebtedness to substantially the
same extent as, or to a greater extent than, the Securities are so subordinated
as provided in this Article. Nothing contained in this Article Fifteen or
elsewhere in this Indenture or in the Securities is intended to or shall impair,
as among the Company, its creditors (other than holders of Senior Indebtedness)
and the Holders, the right, which is absolute and unconditional, of the holder
of any Security to convert such note in accordance with Article Fourteen.
