                              EMPLOYMENT AGREEMENT

                  AGREEMENT by and among Mu Sub, Inc., an Indiana corporation
(the "Company"), Arvin Industries, Inc., an Indiana corporation ("Arvin"), and
V. William Hunt (the "Executive") dated as of the 6th day of April, 2000.

                  The Boards of Directors of the Company and Arvin have
determined that it is in their best interests to assure that Arvin will have the
continued dedication of the Executive pending the consummation of the
transactions contemplated among Meritor, Inc., a Delaware corporation
("Meritor"), the Company, a wholly owned subsidiary of Meritor, and Arvin (the
"Merger") pursuant to the Agreement and Plan of Reorganization dated as of April
6th, 2000 (the "Merger Agreement") and to provide the Company with continuity of
management following the Merger. Therefore, in order to accomplish these
objectives Arvin and the Company have each entered into this Agreement with the
Executive.

                  NOW, THEREFORE, IT IS HEREBY AGREED AS FOLLOWS:

                  1. Effective Date. The "Effective Date" shall mean the
Effective Time as defined in the Merger Agreement.

                  2. Employment Period. Subject to the terms and conditions of
this Agreement, the Company hereby agrees to employ the Executive, and the
Executive hereby agrees to remain in the employ of the Company, for the period
commencing on the Effective Date and ending on October 1, 2003 (the "Employment
Period").

                  3. Terms of Employment. (a) Position and Duties. (i) (A)
During the Employment Period, the Executive shall initially serve as the
President of the Company and as Vice Chairman of the Board of Directors of the
Company (the "Board"), and it is the intention of the parties hereto and of
Meritor to recommend to the Board that the Executive shall serve in the
positions set forth in the following sentence commencing at the times set forth
in the following sentence hereof, in each case, with such duties and
responsibilities as may be assigned to the Executive by the Chief Executive
Officer of Meritor as of the date hereof (the "Current CEO") (while the
Executive is serving as President) and/or by the Board, and as are commensurate
and consistent with such positions, and with the authority as is commensurate
and consistent with such positions, and (B) the Executive, who shall reside in
the Detroit, Michigan area, shall be based at the Company's headquarters. It is
the intention of the parties hereto and of Meritor to recommend to the Board
that, upon the earlier of (x) the retirement or cessation of service of the
Current CEO from the position of Chief Executive Officer of the Company or (y)
October 1, 2002, and subject to the approval of the Board, the Executive shall
commence serving as the Chief Executive Officer of the Company, and, upon the
earlier of (x) the retirement or cessation of service of the Current CEO from
the position of Chairman of the Board or (y) October 1, 2003, and subject to the
approval of the Board, the Executive shall commence serving as the Chairman of
the Board. While the Executive is serving as President of the Company during the
Employment Period, the Executive shall report directly to the Current CEO.
During the
<PAGE>   2
Employment Period, it is intended that the Executive shall serve as a member of
the Board, subject to the Executive's earlier resignation from the Board or
removal from the Board pursuant to the terms of the Company's By-laws.

                           (i) During the Employment Period, and excluding any
periods of vacation and sick leave to which the Executive is entitled, the
Executive agrees to devote his full time and attention to the business and
affairs of the Company and to use his reasonable best efforts to perform
faithfully and efficiently the responsibilities assigned to the Executive
hereunder. During the Employment Period, the Executive will not serve on
corporate boards without the prior approval of the Board. The Executive may also
manage personal investments, so long as such activities do not interfere with
the performance of the Executive's responsibilities to the Company in accordance
with this Agreement. It is expressly understood and agreed that to the extent
that any such activities have been conducted by the Executive prior to the
Effective Date and disclosed in Arvin's Definitive Proxy Statement, dated March
13, 2000, the continued conduct of such activities subsequent to the Effective
Date shall not thereafter be deemed to interfere with the performance of the
Executive's responsibilities to the Company.

                  (b) Compensation. (i) Base Salary. During the Employment
Period, the Executive shall receive an annual base salary (the "Annual Base
Salary") of no less than the Executive's year 2000 annual base salary
($800,000). Beginning October 1, 2000, the Annual Base Salary shall be reviewed,
consistent with the Company's practice for senior executives. Any increase in
Annual Base Salary shall not serve to limit or reduce any other obligation to
the Executive under this Agreement. Annual Base Salary shall not be reduced
after any such increase and the term Annual Base Salary as utilized in this
Agreement shall refer to Annual Base Salary as so increased. As used in this
Agreement, the term "affiliated companies" and "affiliates" shall include any
company controlled by, controlling or under common control with the Company.

                           (ii) Annual Bonus. Beginning October 1, 2000, the
Executive shall be entitled to receive an annual cash bonus (the "Annual
Bonus"), based on a percentage of the Executive's Annual Base Salary, pursuant
to the terms of the Company's annual bonus plan for senior executives, including
the Current CEO, as in effect from time to time. With respect to each fiscal
year during the Employment Period, the Executive's target bonus opportunity
shall be determined by the Compensation and Management Development Committee of
the Board (the "Compensation Committee"). Notwithstanding anything contained
herein to the contrary, with respect to the annual bonus period occurring during
the fiscal year beginning on October 1, 2000, the sum of the Executive's Annual
Base Salary and Annual Bonus shall be at least equal to 90% of the sum of the
annual base salary and annual bonus paid or payable to the Current CEO with
respect to such fiscal year. For the period from the Effective Date through
September 30, 2000, the Executive shall receive a pro rata share of the bonus
for the period from January 1, 2000 through September 30, 2000, determined in
accordance with the Arvin Annual Incentive Plan.

                           (iii) Initial Equity Award. On the Effective Date,
the Company shall grant the Executive an award of restricted shares (the
"Restricted Stock") of the Company's common stock (the "Common Stock") and a
stock option to acquire a number of shares of

                                      -2-
<PAGE>   3
Common Stock (the "Option" and together with the Restricted Stock, the "Initial
Equity Award"), with the "value" of the Initial Equity Award to be equal to the
aggregate of the amounts payable to the Executive, assuming that he were
terminated other than for Cause on the Effective Date, under Section 6(a) of the
Employment Agreement between Arvin and the Executive in the form publicly filed
as an Exhibit to Arvin's Form 10-K filed for the year ended December 28, 1997
(the "Prior Agreement"). For purposes hereof, the "value" of the Initial Equity
Award will be determined on the same basis as the value of the initial equity
awards of Common Stock for the other senior executives of Arvin is determined,
as mutually agreed upon (including, without limitation, the assumptions to be
used for purposes of the Black Scholes valuation methodology), as soon as
reasonably practicable following the date hereof, by the Executive and the
Current CEO. The Initial Equity Award will be granted one-third (1/3) in
restricted shares and two-thirds (2/3) in stock options. The Option will have an
exercise price equal to the fair market value of the Common Stock subject
thereto on the date of grant and a term of ten years from the date of grant
(without regard to the Executive's earlier termination of employment for any
reason). Except as otherwise provided herein, the Restricted Stock and the
Option shall vest in three equal annual installments on each of the first,
second and third anniversaries of the Effective Date, subject to accelerated
vesting upon a "change of control" of the Company (as defined in the stock
incentive plan pursuant to which the Initial Equity Award is granted).

                           (iv) Long-Term Incentive Awards. Beginning October 1,
2000, the Executive shall be entitled to participate in all long-term incentive
plans and programs generally applicable to senior executives of the Company,
including the Current CEO, on a basis and with terms and conditions, including
any applicable performance goals, that are as favorable as the basis and terms
and conditions of the long-term incentive awards of any other senior executive
of the Company, with respect to the same period, provided that, except as
provided below, the Executive's level of participation need not be equal to that
of the Current CEO's level of participation. Notwithstanding anything contained
herein to the contrary, with respect to the 1999 through 2001 long-term
incentive award period, the Executive's long-term incentive award shall be (I)
at least equal to 90% of one-third (1/3) of the cash performance plan long-term
incentive award granted to the Current CEO with respect to such award period and
(II) an award to the Executive on the Effective Date of an option to purchase a
number of shares of Common Stock such that the option will have a Black Scholes
value (determined on the same basis as the Current CEO's long-term incentive
plan award) on the Effective Date that is equal to 90% of one-third (1/3rd) of
the Black Scholes value of the option granted to the Current CEO in respect to
such award period. With respect to the 2000 through 2002 long-term incentive
award period, the Executive's long-term incentive award amount shall be such
amount as the Board, with the advice of the Compensation Committee, may
determine.

                           (v) Other Employee Benefit Plans. During the
Employment Period, except as otherwise expressly provided herein, the Executive
shall be entitled to participate in all employee benefit, welfare and other
plans, practices, policies and programs generally applicable to senior
executives of the Company, including the Current CEO, on a basis no less
favorable than that provided to any other senior executive of the Company,
provided that the Executive's level of participation need not be equal to that
of the Current CEO's level of participation.

                           (vi) Fringe Benefits. During the Employment Period,
the Executive shall be entitled to fringe benefits and perquisites, generally
applicable to senior executives of the Company, including the Current CEO, on a
basis no less favorable than that provided to any

                                      -3-
<PAGE>   4
other senior executive of the Company, provided that the Executive's level of
fringe benefits and perquisites need not be equal to that of the Current CEO's
level of fringe benefits and perquisites.

                           (vii) Expenses. During the Employment Period, the
Executive shall be entitled to receive prompt reimbursement for all reasonable
expenses incurred by the Executive in accordance with the Company's policies.

                           (viii) Office. During the Employment Period, the
Executive shall be entitled to an office at the Company's headquarters of a size
and with furnishings and other appointments as provided generally with respect
to the senior executives of the Company.

                           (ix) Vacation. During the Employment Period, the
Executive shall be entitled to paid vacation in accordance with the plans,
policies, programs and practices of the Company as in effect with respect to the
senior executives of the Company, including the Current CEO.

                  4. Termination of Employment. (a) Death or Disability. The
Executive's employment shall terminate automatically upon the Executive's death
during the Employment Period. If the Company determines in good faith that the
Disability of the Executive has occurred during the Employment Period (pursuant
to the definition of Disability set forth below), it may give to the Executive
written notice in accordance with Section 12(b) of this Agreement of its
intention to terminate the Executive's employment. In such event, the
Executive's employment with the Company shall terminate effective on the 30th
day after receipt of such notice by the Executive (the "Disability Effective
Date"), unless within the 30 days after such receipt, the Executive shall have
furnished to the Company a written determination by a physician selected by the
Company or its insurers and reasonably acceptable to the Executive or the
Executive's legal representative that he has fully recovered from the illness or
condition that led to his absence from his duties and that he is fit to resume
them on a full-time basis. For purposes of this Agreement, "Disability" shall
mean the absence of the Executive from the Executive's duties with the Company
on a full-time basis for an aggregate of 180 calendar days in any consecutive
12-month period or for a period of 120 consecutive calendar days, as a result of
incapacity due to mental or physical illness.

                  (b) Cause. The Company may terminate the Executive's
employment during the Employment Period for Cause. For purposes of this
Agreement, "Cause" shall mean:

                           (i) any failure by the Executive to comply with any
of the provisions of this Agreement, other than an isolated, insubstantial and
inadvertent failure not occurring in bad faith and which is remedied by the
Executive promptly after receipt of notice thereof given by the Company; or

                           (ii) the continued failure of the Executive to
perform substantially the Executive's duties with the Company or one of its
affiliated companies (other than any such failure resulting from incapacity due
to physical or mental illness), after a written demand for substantial
performance is delivered to the Executive by the Board which specifically
identifies

                                      -4-
<PAGE>   5
the manner in which the Board believes that the Executive has not substantially
performed the Executive's duties; or

                           (iii) the willful engaging by the Executive in
illegal conduct or gross misconduct that is materially and demonstrably
injurious to the Company; or

                           (iv) (A) conviction of a felony, or guilty or nolo
contendere plea by the Executive with respect thereto or (B) conviction of
another crime, or guilty or nolo contendere plea by the Executive with respect
thereto that is materially and demonstrably injurious to the Company.

For purposes of this provision, no act or failure to act, on the part of the
Executive, shall be considered "willful" unless it is done, or omitted to be
done, by the Executive in bad faith or without reasonable belief that the
Executive's action or omission was in the best interests of the Company. Any
act, or failure to act, based upon authority given pursuant to a resolution duly
adopted by the Board or based upon the advice of counsel for the Company shall
be conclusively presumed to be done, or omitted to be done, by the Executive in
good faith and in the best interests of the Company. The cessation of employment
of the Executive shall not be deemed to be for Cause unless and until there
shall have been delivered to the Executive a copy of a resolution duly adopted
by the affirmative vote of not less than a majority of the entire membership of
the Board at a meeting of the Board called and held for such purpose (after
reasonable notice is provided to the Executive and the Executive is given an
opportunity, together with counsel, to be heard before the Board), finding that,
in the good faith opinion of the Board, the Executive is guilty of the conduct
described in subparagraph (i), (ii), (iii) or (iv) above, and specifying the
particulars thereof in detail.

                  (c) Good Reason. The Executive's employment may be terminated
by the Executive for Good Reason. For purposes of this Agreement, "Good Reason"
shall mean in the absence of a written consent of the Executive:

                           (i) the assignment to the Executive of any duties
inconsistent in any respect with the Executive's positions (including status,
offices, titles and reporting requirements), authority, duties or
responsibilities as contemplated by Section 3(a) of this Agreement, or any other
action by the Company which results in a diminution in such position, authority,
duties or responsibilities, excluding for this purpose an isolated,
insubstantial and inadvertent action not taken in bad faith and which is
remedied by the Company promptly after receipt of notice thereof given by the
Executive;

                           (ii) any failure by the Company to comply with any of
the provisions of Section 3(b) of this Agreement, other than an isolated,
insubstantial and inadvertent failure not occurring in bad faith and which is
remedied by the Company promptly after receipt of notice thereof given by the
Executive;

                           (iii) the failure to appoint the Executive as Chief
Executive Officer of the Company upon the earlier of (A) the retirement or
cessation of service from such position of the Current CEO or (B) October 1,
2002;

                                      -5-
<PAGE>   6
                           (iv) the failure to appoint the Executive as Chairman
of the Company upon the earlier of (A) the retirement or cessation of service
from such position of the Current CEO or (B) October 1, 2003;

                           (v) the Company's requiring the Executive to be based
at any office or location other than the Company's headquarters;

                           (vi) any purported termination by the Company of the
Executive's employment otherwise than as expressly permitted by this Agreement;
or

                           (vii) any failure by the Company to comply with and
satisfy Section 11(c) of this Agreement.

                  (d) Notice of Termination. Any termination by the Company for
Cause, or by the Executive for Good Reason, shall be communicated by Notice of
Termination to the other party hereto given in accordance with Section 12(b) of
this Agreement. For purposes of this Agreement, a "Notice of Termination" means
a written notice which (i) indicates the specific termination provision in this
Agreement relied upon, (ii) to the extent applicable, sets forth in reasonable
detail the facts and circumstances claimed to provide a basis for termination of
the Executive's employment under the provision so indicated and (iii) if the
Date of Termination (as defined below) is other than the date of receipt of such
notice, specifies the termination date (which date shall be not more than thirty
days after the giving of such notice). The failure by the Executive or the
Company to set forth in the Notice of Termination any fact or circumstance which
contributes to a showing of Good Reason or Cause shall not waive any right of
the Executive or the Company, respectively, hereunder or preclude the Executive
or the Company, respectively, from asserting such fact or circumstance in
enforcing the Executive's or the Company's rights hereunder.

                  (e) Date of Termination. "Date of Termination" means (i) if
the Executive's employment is terminated by the Company for Cause, or by the
Executive for Good Reason (subject to the cure provisions in Sections 4(c)(i)
and (ii)), the date of receipt of the Notice of Termination or any later date
specified therein within 30 days of such notice, as the case may be, (ii) if the
Executive's employment is terminated by the Company other than for Cause or
Disability, the Date of Termination shall be the date on which the Company
notifies the Executive of such termination and (iii) if the Executive's
employment is terminated by reason of death or Disability, the Date of
Termination shall be the date of death of the Executive or the Disability
Effective Date, as the case may be.

                  5. Obligations of the Company upon Termination. (a) Good
Reason; Other Than for Cause, Death or Disability. If, during the Employment
Period, the Company shall terminate the Executive's employment other than for
Cause, death or Disability or the Executive shall terminate employment for Good
Reason:

                           (i) the Company shall pay to the Executive in a lump
sum in cash within 30 days after the Date of Termination the aggregate of the
following amounts:

                  through the Date of Termination to the extent not theretofore
                  paid, (2) the product of (x) the highest annual bonus paid or
                  payable, including any bonus or portion thereof which has been
                  earned but deferred (and annualized for any fiscal year
                  consisting of less than twelve full months), to the Executive
                  for any of the three completed fiscal years immediately prior
                  to the Date of Termination (the "Recent Annual Bonus") and (y)
                  a fraction, the numerator of which is the number of days in
                  the fiscal year in which the Date of Termination occurs
                  through the Date of Termination, and the denominator of which
                  is 365, and (3) any compensation previously deferred by the
                  Executive (together with any accrued interest or earnings
                  thereon) and any accrued vacation pay, in each case to the
                  extent not theretofore paid (the sum of the amounts described
                  in clauses (1), (2) and (3), shall be hereinafter referred to
                  as the "Accrued Obligations"); and

                           B. the amount equal to the product of (1) three and
                  (2) the sum of (x) the Executive's Annual Base Salary and (y)
                  the Recent Annual Bonus; and

                           (ii) the Executive shall be entitled to the immediate
commencement of an annual pension benefit of not less than the Executive's
annual pension benefit calculated under the terms of Arvin's qualified and
non-qualified retirement plans as in effect immediately prior to the Effective
Date, as if the Executive had attained the age and received the service credit
under such plans that the Executive would have attained and received if he had
remained in the employ of the Company for an additional three years after the
Date of Termination and had earned the compensation payable pursuant to Section
5(a)(i) evenly over such three-year period (the "Enhanced Retirement Benefit").
Upon the Executive's death, his spouse as of the date hereof, should she survive
the Executive, shall be paid an annual benefit of 50% of the Enhanced Retirement
Benefit for her life (the "Survivor Retirement Benefit"); and

                           (iii) the Executive and his spouse as of the date

executive officers of the Company for the three-year period following the Date
of Termination, and thereafter, the Executive and his spouse as of the date
hereof shall be provided with retiree medical and dental benefits for the
remainder of each of their lives, on terms and conditions no less favorable than

                           (iv) the Restricted Stock and the Option and all
other equity-based awards granted to the Executive shall immediately vest in

awards, the Executive shall be treated as a retiree (to the extent such
treatment provides him with a longer post-termination exercise period than
otherwise required); and

                                      -7-
<PAGE>   8
                           (v) all long-term incentive awards granted to the
Executive shall immediately vest in full and be paid out based on the maximum
award and/or performance level; and

                           (vi) to the extent not theretofore paid or provided,
the Company shall timely pay or provide to the Executive any other amounts or
benefits required to be paid or provided or which the Executive is eligible to
receive under any plan, program, policy or practice or contract or agreement of
the Company through the Date of Termination (such other amounts and benefits
shall be hereinafter referred to as the "Other Benefits").

                  (b) Death. If the Executive's employment is terminated by
reason of the Executive's death during the Employment Period, this Agreement
shall terminate without further obligations to the Executive's legal
representatives under this Agreement, other than for payment of Accrued
Obligations and the timely payment or provision of Other Benefits. In addition,
the Restricted Stock, the Options and all other equity-based awards granted to
the Executive shall immediately vest in full, and all long-term incentive awards
granted to the Executive shall immediately vest in full and be paid out to the
Executive's estate at the time such amount would otherwise have been payable to
the Executive in an amount that is based on the performance level achieved by
the Company for the fiscal year (in the case of annual incentive awards) and for
the cycle (in the case of long-term incentive awards). The amount of such
long-term incentive awards shall be pro rated through the Executive's date of
death. Accrued Obligations shall be paid to the Executive's estate or
beneficiary, as applicable, in a lump sum in cash within 30 days of the Date of
Termination. With respect to the provision of Other Benefits, the term Other
Benefits as utilized in this Section 5(b) shall include death benefits as in
effect on the date of the Executive's death with respect to senior executives of
the Company, including the Current CEO (but not necessarily the same level of
benefits as the Current CEO), and their beneficiaries and the immediate
commencement of the Survivor Retirement Benefit and the Post-Employment Medical
Benefits for the remainder of the life of the Executive's spouse as of the date
hereof.

                  (c) Disability. If the Executive's employment is terminated by
reason of the Executive's Disability during the Employment Period, this
Agreement shall terminate without further obligations to the Executive, other
than for payment of Accrued Obligations and the timely payment or provision of
Other Benefits. In addition, the Restricted Stock and the Option and all other
equity-based awards granted to the Executive shall immediately vest in full, and
all long-term incentive awards granted to the Executive shall immediately vest
in full and be paid out based on the maximum award and/or performance level.
Accrued Obligations shall be paid to the Executive in a lump sum in cash within
30 days of the Date of Termination. With respect to the provision of Other
Benefits, the term Other Benefits as utilized in this Section 5(c) shall
include, and the Executive shall be entitled after the Disability Effective Date
to receive, disability and other benefits as in effect at any time thereafter
generally with respect to the senior executives of the Company, including the
Current CEO (but not necessarily the same level of benefits as the Current CEO),
and their beneficiaries and the immediate commencement of the Enhanced
Retirement Benefit and the Post-Employment Medical Benefits.

                  (d) Cause; Other than for Good Reason. If the Executive's
employment shall be terminated for Cause or the Executive terminates his
employment without Good Reason during the Employment Period, this Agreement
shall terminate without further obligations to the

                                      -8-
<PAGE>   9
Executive other than the obligation to pay to the Executive (i) the Accrued
Obligations (less the amount described in Section 5(a)(i)(A)(2) and any
compensation deferred following the Effective Date, solely to the extent the
applicable deferred compensation plan requires forfeiture as a result of such
termination without exception) and (ii) Other Benefits. With respect to the
provision of Other Benefits, the term Other Benefits as utilized in this Section
5(d) shall include, and the Executive shall be entitled after the Date of
Termination to receive, the retirement benefits, including, without limitation,
post-retirement medical and dental benefits, as in effect on the Date of
Termination with respect to the senior executives of the Company, including the
Current CEO (but not necessarily the same level of benefits as the Current CEO).

                  6. Non-exclusivity of Rights. Except as specifically provided,
nothing in this Agreement shall prevent or limit the Executive's continuing or
future participation in any plan, program, policy or practice provided by the
Company or any of its affiliated companies and for which the Executive may
qualify, nor, subject to Section 12(f), shall anything herein limit or otherwise
affect such rights as the Executive may have under any contract or agreement
with the Company. Amounts which are vested benefits or which the Executive is
otherwise entitled to receive under any plan, policy, practice or program of or
any contract or agreement with the Company at or subsequent to the Date of
Termination shall be payable in accordance with such plan, policy, practice or
program or contract or agreement except as explicitly modified by this
Agreement.

                  7. Full Settlement. The Company's obligation to make the
payments provided for in this Agreement and otherwise to perform its obligations
hereunder shall not be affected by any set-off, counterclaim, recoupment,
defense or other claim, right or action which the Company may have against the
Executive or others. In no event shall the Executive be obligated to seek other
employment or take any other action by way of mitigation of the amounts payable
to the Executive under any of the provisions of this Agreement and, such amounts
shall not be reduced whether or not the Executive obtains other employment. The
Company agrees to pay as incurred, to the full extent permitted by law, all
legal fees and expenses which the Executive may reasonably incur as a result of
any contest including arbitration (regardless of the outcome thereof) by the
Company, the Executive or others of the validity or enforceability of, or
liability under, any provision of this Agreement or any guarantee of performance
thereof (including as a result of any contest by the Executive about the amount
of any payment pursuant to this Agreement), plus in each case interest on any
delayed payment at the applicable Federal rate provided for in Section
7872(f)(2)(A) of the Internal Revenue Code of 1986, as amended (the "Code").

                  8. Certain Additional Payments by the Company. (a) Anything in
this Agreement to the contrary notwithstanding and except as set forth below, in
the event it shall be determined that any payment or distribution by the Company
to or for the benefit of the Executive (whether paid or payable or distributed
or distributable pursuant to the terms of this Agreement or otherwise, but
determined without regard to any additional payments required under this Section
8) (a "Payment") would be subject to the excise tax imposed by Section 4999

                                      -9-
<PAGE>   10
of the Code or any interest or penalties are incurred by the Executive with
respect to such excise tax (such excise tax, together with any such interest and
penalties, are hereinafter collectively referred to as the "Excise Tax"), then
the Executive shall be entitled to receive an additional payment (a "Gross-Up
Payment") in an amount such that after payment by the Executive of all taxes
(including any interest or penalties imposed with respect to such taxes),
including, without limitation, any income taxes (and any interest and penalties
imposed with respect thereto) and Excise Tax imposed upon the Gross-Up Payment,
the Executive retains an amount of the Gross-Up Payment equal to the Excise Tax
imposed upon the Payments. Notwithstanding the foregoing provisions of this
Section 8(a), if it shall be determined that the Executive is entitled to a
Gross-Up Payment, but that the Executive, after taking into account the Payments
and the Gross-Up Payment, would not receive a net after-tax benefit of at least
$50,000 (taking into account both income taxes and any Excise Tax) as compared
to the net after-tax proceeds to the Executive resulting from an elimination of
the Gross-Up Payment and a reduction of the Payments, in the aggregate, to an
amount (the "Reduced Amount") such that the receipt of Payments would not give
rise to any Excise Tax, then no Gross-Up Payment shall be made to the Executive
and the Payments, in the aggregate, shall be reduced to the Reduced Amount.

                  (b) Subject to the provisions of Section 8(c), all
determinations required to be made under this Section 8, including whether and
when a Gross-Up Payment is required and the amount of such Gross-Up Payment and
the assumptions to be utilized in arriving at such determination, shall be made
by a nationally recognized certified public accounting firm reasonably
acceptable to the Executive as may be designated by the Company (the "Accounting
Firm") which shall provide detailed supporting calculations both to the Company
and the Executive within 15 business days of the receipt of notice from the
Executive that there has been a Payment, or such earlier time as is requested by
the Company. All fees and expenses of the Accounting Firm shall be borne solely
by the Company. Any Gross-Up Payment, as determined pursuant to this Section 8,
shall be paid by the Company to the Executive within five days of (i) the later
of the due date for the payment of any Excise Tax, and (ii) the receipt of the
Accounting Firm's determination. Any determination by the Accounting Firm shall
be binding upon the Company and the Executive. As a result of the uncertainty in
the application of Section 4999 of the Code at the time of the initial
determination by the Accounting Firm hereunder, it is possible that Gross-Up
Payments which will not have been made by the Company should have been made
("Underpayment"), consistent with the calculations required to be made
hereunder. In the event that the Company exhausts its remedies pursuant to
Section 8(c) and the Executive thereafter is required to make a payment of any
Excise Tax, the Accounting Firm shall determine the amount of the Underpayment
that has occurred and any such Underpayment shall be promptly paid by the
Company to or for the benefit of the Executive.

                  (c) The Executive shall notify the Company in writing of any
claim by the Internal Revenue Service that, if successful, would require the
payment by the Company of the Gross-Up Payment. Such notification shall be given
as soon as practicable but no later than ten business days after the Executive
is informed in writing of such claim and shall apprise the Company of the nature
of such claim and the date on which such claim is requested to be paid. The
Executive shall not pay such claim prior to the expiration of the 30-day period
following the date on which it gives such notice to the Company (or such shorter
period ending on the date that

                                      -10-
<PAGE>   11
any payment of taxes with respect to such claim is due). If the Company notifies
the Executive in writing prior to the expiration of such period that it desires
to contest such claim, the Executive shall:

                           (i) give the Company any information reasonably
requested by the Company relating to such claim,

                           (ii) take such action in connection with contesting
such claim as the Company shall reasonably request in writing from time to time,
including, without limitation, accepting legal representation with respect to
such claim by an attorney reasonably selected by the Company,

                           (iii) cooperate with the Company in good faith in
order effectively to contest such claim, and

                           (iv) permit the Company to participate in any
proceedings relating to such claim;

provided, however, that the Company shall bear and pay directly all costs and
expenses (including additional interest and penalties) incurred in connection
with such contest and shall indemnify and hold the Executive harmless, on an
after-tax basis, for any Excise Tax or income tax (including interest and
penalties with respect thereto) imposed as a result of such representation and
payment of costs and expenses. Without limitation on the foregoing provisions of
this Section 8(c), the Company shall control all proceedings taken in connection
with such contest and, at its sole option, may pursue or forgo any and all
administrative appeals, proceedings, hearings and conferences with the taxing
authority in respect of such claim and may, at its sole option, either direct
the Executive to pay the tax claimed and sue for a refund or contest the claim
in any permissible manner, and the Executive agrees to prosecute such contest to
a determination before any administrative tribunal, in a court of initial
jurisdiction and in one or more appellate courts, as the Company shall
determine; provided, however, that if the Company directs the Executive to pay
such claim and sue for a refund, the Company shall advance the amount of such
payment to the Executive, on an interest-free basis and shall indemnify and hold
the Executive harmless, on an after-tax basis, from any Excise Tax or income tax
(including interest or penalties with respect thereto) imposed with respect to
such advance or with respect to any imputed income with respect to such advance;
and further provided that any extension of the statute of limitations relating
to payment of taxes for the taxable year of the Executive with respect to which
such contested amount is claimed to be due is limited solely to such contested
amount. Furthermore, the Company's control of the contest shall be limited to
issues with respect to which a Gross-Up Payment would be payable hereunder and
the Executive shall be entitled to settle or contest, as the case may be, any
other issue raised by the Internal Revenue Service or any other taxing
authority.

                  (d) If, after the receipt by the Executive of an amount
advanced by the Company pursuant to Section 8(c), the Executive becomes entitled
to receive any refund with respect to such claim, the Executive shall (subject
to the Company's complying with the requirements of Section 8(c)) promptly pay
to the Company the amount of such refund (together

                                      -11-
<PAGE>   12
with any interest paid or credited thereon after taxes applicable thereto). If,
after the receipt by the Executive of an amount advanced by the Company pursuant
to Section 8(c), a determination is made that the Executive shall not be
entitled to any refund with respect to such claim and the Company does not
notify the Executive in writing of its intent to contest such denial of refund
prior to the expiration of 30 days after such determination, then such advance
shall be forgiven and shall not be required to be repaid and the amount of such
advance shall offset, to the extent thereof, the amount of Gross-Up Payment
required to be paid.

                  9. Confidential Information/Non-Competition/Non-Solicitation.
(a) The Executive shall hold in a fiduciary capacity for the benefit of the
Company all secret or confidential information, knowledge or data relating to
the Company or any of its affiliated companies, and their respective businesses,
which shall have been obtained by the Executive during the Executive's
employment by the Company or any of its affiliated companies and which shall not
be or become public knowledge (other than by acts by the Executive or
representatives of the Executive in violation of this Agreement). After
termination of the Executive's employment with the Company, the Executive shall
not, without the prior written consent of the Company or as may otherwise be
required by law or legal process, communicate or divulge any such information,
knowledge or data to anyone other than the Company and those designated by it.

                  (b) The Executive agrees that, (i) while the Executive is
employed during the Employment Period or (ii) for a period of two years
following the date on which the Executive's employment hereunder is terminated
by the Company for Cause or by the Executive without Good Reason, whichever
period in (i) or (ii) is applicable the Executive will not, without the written
consent of the Company, engage in any business of, or enter the employ of, or
have any interest in, directly or indirectly, any other person, firm,
corporation or other entity engaged in a business that is in substantial and
direct competition with the Company as of the Date of Termination. Nothing
herein shall restrict the Executive from owning 2% or less of the outstanding
securities of any corporation or other entity whose securities are listed on any
national securities exchange or traded over-the-counter, if the Executive has no
other connection or relationship with the issuer of such securities.

                  (c) The Executive agrees that, during the Employment Period
and for a period of two years following the date on which the Executive's
employment hereunder is terminated by the Company for Cause or by the Executive
without Good Reason, the Executive will not, directly or indirectly, on behalf
of the Executive or any other person, solicit for employment by other than the
Company any person employed by the Company at the Effective Date, nor will the
Executive, directly or indirectly, on behalf of the Executive or any other
person, solicit for employment by other than the Company any person known by the
Executive to be employed at the time by the Company.

                  (d) In the event of a breach or threatened breach of this
Section 9, the Executive agrees that the Company shall be entitled to injunctive
relief in a court of appropriate jurisdiction to remedy any such breach or
threatened breach, the Executive acknowledges that damages would be inadequate
and insufficient. The termination of the Executive's employment hereunder shall
have no effect on the continuing operation of this Section 9. In no event shall
an

                                      -12-
<PAGE>   13
asserted violation of the provisions of this Section 9 constitute a basis for
deferring or withholding any amounts otherwise payable to the Executive under
this Agreement.

                  10. Resolution of Disputes. Any controversy or claim arising
out of or relating to this Agreement shall at the request of either party be
determined by arbitration. The arbitration shall be held in Indiana and
conducted in accordance with the National Rules for the Resolution of Employment
Disputes of the American Arbitration Association. The dispute shall be submitted
to a single arbitrator to be mutually agreed upon by the parties. If the parties
cannot agree on a single arbitrator, each party shall appoint one arbitrator who
shall then jointly appoint a single arbitrator. Judgment upon the arbitration
award may be entered in any court having jurisdiction. The institution and
maintenance of an action for judicial relief or pursuit of a provisional or
ancillary remedy shall not constitute a waiver of the right of any party,
including the plaintiff, to submit the controversy or claim to arbitration if
any other party contests such action for judicial relief. The Company agrees to
pay the costs of the arbitration and to reimburse the Executive for reasonable
expenses incurred as a result of such arbitration.

                  11. Successors. (a) This Agreement is personal to the
Executive and without the prior written consent of the Company shall not be
assignable by the Executive otherwise than by will or the laws of descent and
distribution. This Agreement shall inure to the benefit of and be enforceable by
the Executive's legal representatives.

                  (b) This Agreement shall inure to the benefit of and be
binding upon the Company and its successors and assigns.

                  (c) The Company will require any successor (whether direct or
indirect, by purchase, merger, consolidation or otherwise) to all or
substantially all of the business and/or assets of the Company to assume
expressly and agree to perform this Agreement in the same manner and to the same
extent that the Company would be required to perform it if no such succession
had taken place. As used in this Agreement, "Company" and "Arvin" shall mean the
Company and Arvin as hereinbefore defined and any successor to their respective
businesses and/or assets as aforesaid which assumes and agrees to perform this
Agreement by operation of law, or otherwise.

                  12. Miscellaneous. (a) This Agreement shall be governed by and
construed in accordance with the laws of the State of Indiana, without reference
to principles of conflict of laws. The captions of this Agreement are not part
of the provisions hereof and shall have no force or effect. This Agreement may
not be amended or modified otherwise than by a written agreement executed by the
parties hereto or their respective successors and legal representatives.

                  All notices and other communications hereunder shall be in
writing and shall be given by hand delivery to the other party or by registered

or to such other address as either party shall have furnished to the other in
writing in accordance herewith. Notice and communications shall be effective
when actually received by the addressee.

                  (c) The invalidity or unenforceability of any provision of
this Agreement shall not affect the validity or enforceability of any other
provision of this Agreement.

                  (d) The Company may withhold from any amounts payable under
this Agreement such Federal, state, local or foreign taxes as shall be required
to be withheld pursuant to any applicable law or regulation.

                  (e) The Executive's or the Company's failure to insist upon
strict compliance with any provision of this Agreement or the failure to assert
any right the Executive or the Company may have hereunder, including, without
limitation, the right of the Executive to terminate employment for Good Reason
pursuant to Section 4(c)(i)-(vii) of this Agreement, shall not be deemed to be a
waiver of such provision or right or any other provision or right of this
Agreement.

                  (f) Subject to compliance with the terms hereof as of the
Effective Date, from and after the Effective Date this Agreement shall supersede
any other employment, severance or change of control agreement between the
Executive and Arvin with respect to the subject matter hereof. This Agreement
shall be of no force and effect if the "Effective Time" (as defined in the
Merger Agreement) of the Merger does not occur.

                  (g) This Agreement may be executed in several counterparts,
each of which shall be deemed to be an original but all of which together will
constitute one and the same instrument.

behalf, and Meritor has cause these presents to be executed by Mu Sub, all as of

thereof, subject to Section 2.01(8). The Notes of a particular Series shall bear
interest payable on the Interest Payment Dates and at the rate or rates
specified with respect to that Series. Principal of and the interest on the
Notes of any Series, as well as any premium thereon in case of redemption
thereof prior to maturity, shall be payable in the coin or currency of the
United States of America that at the time is legal tender for public and private
debt, at the office or agency of the Company maintained for that purpose in the
Borough of Manhattan, the City and State of New York. Each Note shall be dated
the date of its authentication. Unless otherwise provided pursuant to Section
2.01, interest on the Notes shall be computed on the basis of a 360-day year
composed of twelve 30-day months.

         The interest installment on any Note that is payable, and is punctually
paid or duly provided for, on any Interest Payment Date for Notes of that Series
shall be paid to the Person in whose name said Note (or one or more Predecessor
Notes) is registered at the close of business on the regular record date for
such interest installment. In the event that any Note of a particular Series or
portion thereof is called for redemption and the redemption date is subsequent
to a regular record date with respect to any Interest Payment Date and prior to
such Interest Payment Date, interest on such Note will be paid upon presentation
and surrender of such Note as provided in Section 3.03.

         Any interest on any Note that is payable, but is not punctually paid or
duly provided for, on any Interest Payment Date for Notes of the same Series
(herein called "Defaulted Interest") shall forthwith cease to be payable to the
registered holder on the relevant regular record date by virtue of having been
such holder; and such Defaulted Interest shall be paid by the Company, at its
election, as provided in clause (1) or clause (2) below:

                  (1) The Company may make payment of any Defaulted Interest on
         Notes to the Persons in whose names such Notes (or their respective
         Predecessor Notes) are registered at the close of business on a special
         record date for the payment of such Defaulted Interest, which shall be
         fixed in the following manner: the Company shall notify the Trustee in
         writing of the amount of Defaulted Interest proposed to be paid on each
         such Note 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

                                       11

<PAGE>   16

         which shall not be more than 15 nor less than 10 days prior to the date
         of the proposed payment and not less than 10 days after the receipt by
         the Trustee of the notice of the proposed payment. The Trustee shall
         promptly notify the Company of such special record date and, in the
         name and at the expense of the Company, shall cause notice of the
         proposed payment of such Defaulted Interest and the special record date
         therefor to be mailed, first class postage prepaid, to each Note holder
         at his or her address as it appears in the Register, not less than 10
         days prior to such special record date. Notice of the proposed payment
         of such Defaulted Interest and the special record date therefor having
         been mailed as aforesaid, such Defaulted Interest shall be paid to the
         Persons in whose names such Notes (or their respective Predecessor
         Notes) are registered at the close of business on such special record
         date and shall be no longer payable pursuant to the following clause
         (2).

                  (2) The Company may make payment of any Defaulted Interest on
         any Notes in any other lawful manner 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.

         Unless otherwise set forth in a Board Resolution of the Company or one
or more indentures supplemental hereto establishing the terms of any Series of
Notes pursuant to Section 2.01 hereof, the term "regular record date" as used in
this Section with respect to a Series of Notes with respect to any Interest
Payment Date for such Series shall mean either the fifteenth day of the month
immediately preceding the month in which an Interest Payment Date established
for such Series pursuant to Section 2.01 hereof shall occur, if such Interest
Payment Date is the first day of a month, or the last day of the month
immediately preceding the month in which an Interest Payment Date established
for such Series pursuant to Section 2.01 hereof shall occur, if such Interest
Payment Date is the fifteenth day of a month, whether or not such date is a
Business Day.

         Subject to the foregoing provisions of this Section, each Note of a
Series delivered under this Indenture upon transfer of or in exchange for or in
lieu of any other Note of such Series shall carry the rights to interest accrued
and unpaid, and to accrue, that were carried by such other Note.

         SECTION 2.04 Execution and Authentication.

         The Notes shall be signed on behalf of the Company by the Chairman of
the Board of Directors, the Vice Chairman, the President or any Vice President,
together with its Treasurer, or one of its Assistant Treasurers, or its
Secretary, or one of its Assistant Secretaries, under its corporate seal which
may, but need not be, attested by its Secretary or

                                       12

<PAGE>   17

one of its Assistant Secretaries. Signatures may be in the form of a manual or
facsimile signature. Notes 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 Notes or did
not hold such offices at the date of such Notes. The seal of the Company may be
in the form of a facsimile of such seal and may be impressed, affixed, imprinted
or otherwise reproduced on the Notes. The Notes may contain such notations,
legends or endorsements required by law or usage. Each Note shall be dated the
date of its authentication by the Trustee.

         A Note shall not be valid until authenticated manually by an authorized
signatory of the Trustee. Such signature shall be conclusive evidence that the
Note so authenticated has been duly authenticated and delivered hereunder and
that the holder is entitled to the benefits of this Indenture. Notwithstanding
the foregoing, if any Note shall have been authenticated and delivered hereunder
but never issued and sold by the Company, and the Company shall deliver such
Note to the Trustee for cancellation as provided in Section 2.08, for all
purposes of this Indenture such Note shall be deemed never to have been
authenticated and delivered hereunder and shall never be entitled to the
benefits of this Indenture.

         At any time and from time to time after the execution and delivery of
this Indenture, the Company may deliver Notes of any Series executed by the
Company to the Trustee for authentication, together with a written order of the
Company for the authentication and delivery of such Notes, signed by its
Chairman of the Board of Directors, the Vice Chairman, the President or any Vice
President, together with its Treasurer, or one of its Assistant Treasurers, or
its Secretary, or one of its Assistant Secretaries, and the Trustee in
accordance with such written order shall authenticate and deliver such Notes.

         In authenticating such Notes and accepting the additional
responsibilities under this Indenture in relation to such Notes, the Trustee
shall be entitled to receive, and (subject to Section 7.01) shall be fully
protected in relying upon, an Opinion of Counsel stating that the form and terms
thereof have been established in conformity with the provisions of this
Indenture and that such Notes, 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 relative to or affecting creditors' rights
and to general equity principles.

         The Trustee shall not be required to authenticate such Notes if the
issue of such Notes pursuant to this Indenture will affect the Trustee's own
rights, duties or immunities under the

                                       13

<PAGE>   18

Notes and this Indenture or otherwise in a manner that is not reasonably
acceptable to the Trustee.

         SECTION 2.05 Registration of Transfer and Exchange.

         (a) Notes of any Series may be exchanged upon presentation thereof at
the Trustee's Corporate Office for other Notes of such Series of authorized
denominations, and for a like aggregate principal amount and of like tenor, upon
payment of a sum sufficient to cover any tax or other governmental charge in
relation thereto, all as provided in this Section. In respect of any Notes so
surrendered for exchange, the Company shall execute, the Trustee shall
authenticate and such office or agency shall deliver in exchange therefor the
Note or Notes of the same Series that the Noteholder making the exchange shall
be entitled to receive, bearing numbers not contemporaneously outstanding.

         (b) The Company shall keep, or cause to be kept, the Register at the
Trustee's Corporate Office or at such other location(s) as may from time to time
be designated by the Company, in which, subject to such reasonable regulations
as the Company may prescribe, the Company shall register the Notes and the
transfers of Notes as in this Article provided. The Register shall at all
reasonable times be open for inspection by the Trustee. Unless otherwise
specified in a supplemental indenture, the Trustee is hereby appointed as
Registrar for the purpose of registering Notes and transfer of Notes of each
Series.

         Upon surrender for transfer of any Note at the office or agency of the
Company designated for such purpose, the Company shall execute, the Trustee
shall authenticate and such office or agency shall deliver in the name of the
transferee or transferees a new Note or Notes of the same Series as the Note
presented of any authorized denominations for a like aggregate principal amount
and of like tenor.

         All Notes presented or surrendered for exchange or registration of
transfer, as provided in this Section, shall be accompanied (if so required by
the Company or the Registrar) by a written instrument or instruments of
transfer, in form satisfactory to the Company or the Registrar, duly executed by
the registered holder or by such holder's duly authorized attorney in writing.

         (c) No service charge shall be made for any exchange or registration of
transfer of Notes, or issue of new Notes in case of partial redemption of any
Series, but the Company may require payment of a sum sufficient to cover any tax
or other governmental charge in relation thereto, other than exchanges pursuant
to Section 2.06, Section 3.03(b) and Section 9.04 not involving any transfer.

                                       14

<PAGE>   19

         (d) The Company shall not be required (i) to issue, exchange or
register the transfer of any Notes of a Series during a period beginning at the
opening of business 15 days before the day of the mailing of a notice of
redemption of less than all the outstanding Notes of the same Series and ending
at the close of business on the day of such mailing, nor (ii) to register the
transfer of or exchange any Notes of any Series or portions thereof called for
redemption except the unredeemed portion of any Notes of any Series being
redeemed in part. The provisions of this Section 2.05 are subject to Section
2.11 hereof.

         SECTION 2.06 Temporary Notes.

         Pending the preparation of definitive Notes of any Series, the Company
may execute, and the Trustee shall authenticate and deliver, temporary Notes
(printed, lithographed or typewritten) of any authorized denomination. Such
temporary Notes shall be substantially in the form of the definitive Notes in
lieu of which they are issued, but with such omissions, insertions and
variations as may be appropriate for temporary Notes, all as may be determined
by the Company. Every temporary Note of any Series shall be executed by the
Company and be authenticated by the Trustee upon the same conditions and in
substantially the same manner, and with like effect, as the definitive Notes of
such Series. Without unnecessary delay the Company will execute and will furnish
definitive Notes of such Series and thereupon any or all temporary Notes of such
Series may be surrendered in exchange therefor (without charge to the holders),
at the office or agency of the Company maintained for that purpose in the
Borough of Manhattan, the City and State of New York, and the Trustee shall
authenticate and such office or agency shall deliver in exchange for such
temporary Notes an equal aggregate principal amount of definitive Notes of such
Series, unless the Company advises the Trustee to the effect that definitive
Notes need not be executed and furnished until further notice from the Company.
Until so exchanged, the temporary Notes of such Series shall be entitled to the
same benefits under this Indenture as definitive Notes of such Series
authenticated and delivered hereunder.

         SECTION 2.07  Mutilated, Destroyed, Lost or Stolen Notes.

         In case any temporary or definitive Note shall become mutilated or be
destroyed, lost or stolen, the Company (subject to the next succeeding sentence)
shall execute, and upon the Company's request the Trustee (subject as aforesaid)
shall authenticate and deliver, a new Note of the same Series and of like tenor
and principal amount, bearing a number not contemporaneously outstanding, in
exchange and substitution for the mutilated Note, or in lieu of and in
substitution for the Note so destroyed, lost or stolen. In every case the
applicant for a substituted Note shall furnish to the Company and the Trustee
such security or indemnity as may be required by them to save each of them
harmless, and, in every case of destruction, loss or theft, the applicant shall
also furnish to the Company and the Trustee

                                       15

<PAGE>   20

evidence to their satisfaction of the destruction, loss or theft of the
applicant's Note and of the ownership thereof. The Trustee may authenticate any
such substituted Note and deliver the same upon the written request or
authorization of any officer of the Company. Upon the issuance of any
substituted Note, 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. In case any Note that has matured or is about to mature
shall become mutilated or be destroyed, lost or stolen, the Company may, instead
of issuing a substitute Note, pay or authorize the payment of the same (without
surrender thereof except in the case of a mutilated Note) if the applicant for
such payment shall furnish to the Company and the Trustee such security or
indemnity as they may require to save them harmless, and, in case of
destruction, loss or theft, evidence to the satisfaction of the Company and the
Trustee of the destruction, loss or theft of such Note and of the ownership
thereof.

         Every replacement Note issued pursuant to the provisions of this
Section shall constitute an additional contractual obligation of the Company
whether or not the mutilated, destroyed, lost or stolen Note shall be found at
any time, or be enforceable by anyone, and shall be entitled to all the benefits
of this Indenture equally and proportionately with any and all other Notes of
the same Series duly issued hereunder. All Notes shall be held and owned upon
the express condition that the foregoing provisions are exclusive with respect
to the replacement or payment of mutilated, destroyed, lost or stolen Notes, and
shall preclude (to the extent lawful) any and all other rights or remedies,
notwithstanding any law or statute existing or hereafter enacted to the contrary
with respect to the replacement or payment of negotiable instruments or other
securities without their surrender.

         SECTION 2.08  Cancellation.

         All Notes surrendered for the purpose of payment, redemption, exchange
or registration of transfer shall, if surrendered to the Company or any Paying
Agent, be delivered to the Trustee for cancellation, or, if surrendered to the
Trustee, shall be canceled by it, and no Notes shall be issued in lieu thereof
except as expressly required or permitted by any of the provisions of this
Indenture. On request of the Company at the time of such surrender, the Trustee
shall deliver to the Company canceled Notes held by the Trustee. In the absence
of such request the Trustee may dispose of canceled Notes in accordance with its
standard procedures and deliver a certificate of disposition to the Company. If
the Company shall otherwise acquire any of the Notes, however, such acquisition
shall not operate as a redemption or satisfaction of the indebtedness
represented by such Notes unless and until the same are delivered to the Trustee
for cancellation.

                                       16

<PAGE>   21

         SECTION 2.09 Benefits of Indenture.

         Nothing in this Indenture or in the Notes, express or implied, shall
give or be construed to give to any Person, other than the parties hereto and
the holders of the Notes any legal or equitable right, remedy or claim under or
in respect of this Indenture, or under any covenant, condition or provision
herein contained; all such covenants, conditions and provisions being for the
sole benefit of the parties hereto and of the holders of the Notes.

         SECTION 2.10 Authenticating Agent.

         So long as any of the Notes of any Series remain outstanding there may
be an Authenticating Agent for any or all such Series of Notes which the
Trustee, with the consent of the Company, shall have the right to appoint. Said
Authenticating Agent shall be authorized to act on behalf of the Trustee to
authenticate Notes of such Series issued upon exchange, transfer or partial
redemption thereof, and Notes 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. All references in this Indenture to the
authentication of Notes by the Trustee shall be deemed to include authentication
by an Authenticating Agent for such Series. Each Authenticating Agent shall be a
corporation that has a combined capital and surplus, as most recently reported
or determined by it, sufficient under the laws of any jurisdiction under which
it is organized or in which it is doing business to conduct a trust business,
and that is otherwise authorized under such laws to conduct such business and is
subject to supervision or examination by Federal or State authorities. If at any
time any Authenticating Agent shall cease to be eligible in accordance with
these provisions, it shall resign immediately.

         Any Authenticating Agent may at any time resign by giving written
notice of resignation to the Trustee and to the Company. The Trustee may at any
time (and upon request by the Company shall) terminate the agency of any
Authenticating Agent by giving written notice of termination to such
Authenticating Agent and to the Company. Upon resignation, termination or
cessation of eligibility of any Authenticating Agent, the Trustee may appoint an
eligible successor Authenticating Agent acceptable to the Company. Any successor
Authenticating Agent, upon acceptance of its appointment hereunder, shall become
vested with all the rights, powers and duties of its predecessor hereunder as if
originally named as an Authenticating Agent pursuant hereto. No successor
Authenticating Agent shall be appointed unless eligible under the provisions of
this Section.

         SECTION 2.11 Global Notes.

         (a) With respect to each Series of Notes issued under this Indenture,
the Company shall execute and the Trustee shall, in accordance with Section
2.04, authenticate and deliver,

                                       17

<PAGE>   22

a Global Note that (i) shall represent, and shall be denominated in an amount
equal to the aggregate principal amount of, such of the Outstanding Notes of
such Series as shall be specified therein, provided that the aggregate amount of
Outstanding Notes represented thereby may from time to time be increased or
reduced to reflect exchanges, (ii) shall be registered in the name of the
Depositary or its nominee, (iii) shall be delivered by the Trustee to the
Depositary or pursuant to the Depositary's instruction and (iv) shall bear a
legend substantially to the following effect: "Except as otherwise provided in
Section 2.11 of the Indenture, this Note may be transferred, in whole but not in
part, only to another nominee of the Depositary or to a successor Depositary or
to a nominee of such successor Depositary." Any endorsement of a Note in global
form to reflect the amount, or any increase or decrease in the amount, of
Outstanding Notes represented thereby shall be made by the Trustee in such
manner and upon instructions given by such Person or Persons as shall be
specified therein or in the written request signed in the name of the Company,
by the Chairman of the Board of Directors, the Vice Chairman, the President or
any Vice President and by the Secretary or an Assistant Secretary or the
Treasurer or an Assistant Treasurer thereof to be delivered to the Trustee
pursuant to Section 2.04 or Section 2.06.

         (b) Notwithstanding the provisions of Section 2.05, the Global Note of
a Series may be transferred, in whole but not in part and in the manner provided
in Section 2.05, only to another nominee of the Depositary for such Series, or
to a successor Depositary for such Series selected or approved by the Company or
to a nominee of such successor Depositary.

         (c) If at any time the Depositary for a Series of Notes notifies the
Company that it is unwilling or unable to continue as Depositary for such Series
or if at any time the Depositary for such Series shall no longer be registered
or in good standing under the Exchange Act, or other applicable statute or
regulation, and a successor Depositary for such Series is not appointed by the
Company within 90 days after the Company receives such notice or becomes aware
of such condition, as the case may be, this Section 2.11 shall no longer be
applicable to the Notes of such Series and the Company will execute, and subject
to Section 2.05, the Trustee will authenticate and deliver the Notes of such
Series in definitive registered form without coupons, in authorized
denominations, and in an aggregate principal amount equal to the principal
amount of the Global Note of such Series in exchange for such Global Note. In
addition, the Company may at any time determine that the Notes of any Series
shall no longer be represented by a Global Note and that the provisions of this
Section 2.11 shall no longer apply to the Notes of such Series. In such event
the Company will execute and subject to Section 2.05, the Trustee, upon receipt
of an Officers' Certificate evidencing such determination by the Company, will
authenticate and deliver the Notes of such Series in definitive registered form
without coupons, in authorized denominations, and in an aggregate principal
amount equal to the principal amount of the Global Note of such Series in
exchange for such Global Note. Upon the exchange of the Global Note for such

                                       18

<PAGE>   23

Notes in definitive registered form without coupons, in authorized
denominations, the Global Note shall be canceled by the Trustee. Such Notes in
definitive registered form issued in exchange for the Global Note pursuant to
this Section 2.11(c) shall be registered in such names and in such authorized
denominations as the Depositary, pursuant to instructions from its direct or
indirect participants or otherwise, shall instruct the Trustee. The Trustee
shall deliver such Notes to the Depositary for delivery to the Persons in whose
names such Notes are so registered.

                                  ARTICLE III.
                               REDEMPTION OF NOTES

         SECTION 3.01  Redemption.

         The Company may redeem the Notes of any Series issued hereunder on and
after the dates and in accordance with the terms established for such Series
pursuant to Section 2.01 hereof.

         SECTION 3.02 Notice of Redemption.

         (a) In case the Company shall desire to exercise such right to redeem
all or, as the case may be, a portion of the Notes of any Series in accordance
with the right reserved so to do, the Company shall, or shall cause the Trustee
to, give notice of such redemption to holders of the Notes of such Series to be
redeemed by mailing, first-class postage prepaid, a notice of such redemption
not less than 30 days and not more than 60 days before the date fixed for
redemption of Notes of that Series to such holders at their last addresses as
they shall appear upon the Register unless a shorter period is specified in the
Notes to be redeemed. Any notice that is mailed in the manner herein provided
shall be conclusively presumed to have been duly given, whether or not the
registered holder receives the notice. In any case, failure duly to give such
notice to the holder of any Note of any Series designated for redemption in
whole or in part, or any defect in the notice, shall not affect the validity of
the proceedings for the redemption of any other Notes of such Series or any
other Series. In the case of any redemption of Notes prior to the expiration of
any restriction on such redemption provided in the terms of such Notes or
elsewhere in this Indenture, the Company shall furnish the Trustee with an
Officers' Certificate evidencing compliance with any such restriction.

         Each such notice of redemption shall specify the date fixed for
redemption and the redemption price (or the manner of calculation thereof) at
which Notes of that Series are to be redeemed, and shall state that payment of
the redemption price of such Notes to be redeemed will be made at the office or
agency of the Company maintained for that purpose

                                       19

<PAGE>   24

in the Borough of Manhattan, the City and State of New York, upon presentation
and surrender of such Notes, that interest accrued to the date fixed for
redemption will be paid as specified in said notice and that from and after said
date interest will cease to accrue. If less than all the Notes of a Series are
to be redeemed, the notice to the holders of Notes of that Series to be redeemed
in whole or in part shall specify the particular Notes to be so redeemed. In
case any Note is to be redeemed in part only, the notice that relates to such
Note shall state the portion of the principal amount thereof to be redeemed, and
shall state that on and after the redemption date, upon surrender of such Note,
a new Note or Notes of such Series in principal amount equal to the unredeemed
portion thereof will be issued.

         Prior to any redemption date, the Company shall deposit with the
Trustee or with a Paying Agent (or, if the Company is acting as its own Paying
Agent, segregate and hold in trust as provided in Section 4.03(b)) an amount of
money sufficient to pay the redemption price of, and accrued interest on, all
the Notes which are to be redeemed on that date.

         (b) If less than all the Notes of a Series are to be redeemed, the
Company shall give the Trustee at least 45 days' notice in advance of the date
fixed for redemption as to the aggregate principal amount of Notes of the Series
to be redeemed, and thereupon the Trustee shall select, by lot or in such other
manner as it shall deem appropriate and fair in its discretion and that may
provide for the selection of a portion or portions (equal to one thousand U.S.
dollars ($1,000) or any integral multiple thereof) of the principal amount of
such Notes of a denomination larger than $1,000, the Notes to be redeemed and
shall thereafter promptly notify the Company in writing of the numbers of the
Notes to be redeemed, in whole or in part.

         Subject to the provisions of Section 3.01, the Company may, if and
whenever it shall so elect, by delivery of instructions signed on its behalf by
the Chairman of the Board of Directors, the Vice Chairman, the President or any
Vice President, instruct the Trustee or any Paying Agent to call all or any part
of the Notes of a particular Series for redemption and to give notice of
redemption in the manner set forth in this Section, such notice to be in the
name of the Company or its own name as the Trustee or such Paying Agent may deem
advisable. In any case in which notice of redemption is to be given by the
Trustee or such Paying Agent, the Company shall deliver or cause to be delivered
to, or permit to remain with, the Trustee or such Paying Agent, as the case may
be, such Register, transfer books or other records, or suitable copies or
extracts therefrom, sufficient to enable the Trustee or such Paying Agent to
give any notice by mail (at the expense of the Company) that may be required
under the provisions of this Section.

                                       20

<PAGE>   25

         SECTION 3.03  Payment Upon Redemption.

         (a) If the giving of notice of redemption shall have been completed as
above provided, the Notes or portions of Notes of the Series to be redeemed
specified in such notice shall become due and payable on the date and at the
place stated in such notice at the applicable redemption price, together with
interest accrued to the date fixed for redemption and interest on such Notes or
portions of Notes shall cease to accrue on and after the date fixed for
redemption, unless the Company shall default in the payment of such redemption
price and accrued interest with respect to any such Note or portion thereof. On
presentation and surrender of such Notes on or after the date fixed for
redemption at the place of payment specified in the notice, said Notes shall be
paid and redeemed at the applicable redemption price for such Series, together
with interest accrued thereon to the date fixed for redemption (but if the date
fixed for redemption is an Interest Payment Date, the interest installment
payable on such Interest Payment Date shall be payable to the registered holder
at the close of business on the applicable record date pursuant to Section
2.03).

         (b) Upon presentation of any Note of such Series that is to be redeemed
in part only, the Company shall execute and the Trustee shall authenticate and
the office or agency where the Note is presented shall deliver to the holder

         SECTION 4.01 Payment of Principal, Premium and Interest.

         The Company will duly and punctually pay or cause to be paid the

         SECTION 4.02      Maintenance of Office or Agency.

         So long as any Notes remain Outstanding, the Company shall maintain an
office or agency of the Company in the Borough of Manhattan, City or State of
New York, together with such other location or locations as may be designated as
provided in this Section 4.02, where (i) Notes may be presented for payment,
(ii) Notes may be presented as authorized in this Indenture for registration of
transfer and exchange, and (iii) notices and demands to or upon the Company in

<PAGE>   26
other office or agency for such purposes or any of them. 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, notices and
demands may be made or served at the Trustee's Corporate Office, and the Company
hereby appoints the Trustee as its agent to receive all such presentations,
notices and demands.

         SECTION 4.03      Paying Agents.

         (a) If the Company shall appoint one or more Paying Agents for all or
any Series of Notes, other than the Trustee, the Company will cause each Paying
Agent to execute and deliver to the Trustee an instrument in which such agent
shall agree with the Trustee, subject to the provisions of this Section:

                  (1) that it will hold all sums held by it as such agent for
         the payment of the principal of and any premium or interest on the
         Notes of that Series (whether such sums have been paid to it by the
         Company or by any other obligor of such Notes) in trust for the benefit
         of the Persons entitled thereto;

                  (2) that it will give the Trustee notice of any failure by the
         Company (or by any other obligor of such Notes) to make any payment of
         the principal of and any premium or interest on the Notes of that
         Series when the same shall be due and payable;

                  (3) that it will, at any time during the continuance of any
         failure referred to in the subsection (a)(2) above, upon the written
         request of the Trustee, forthwith pay to the Trustee all sums held in
         trust pursuant to subsection (a)(1); and

                  (4) that it will perform all other duties of Paying Agent as
         set forth in this Indenture and as required by the Trust Indenture Act.

         (b) If the Company shall act as its own paying agent with respect to
any Series of Notes, it will on or before each due date of the principal of and
any premium or interest on Notes of that Series, set aside, segregate and hold
in trust for the benefit of the Persons entitled thereto a sum sufficient to pay
such principal and any premium or interest so becoming due on Notes of that
Series until such sums shall be paid to such Persons or otherwise disposed of as
herein provided and will promptly notify the Trustee of such action, or any
failure (by it or any other obligor on such Notes) to take such action. Whenever
the Company shall have one or more Paying Agents for any Series of Notes, it
will, prior to each due date of the principal of and any premium or interest on
any Notes of that Series, deposit with the Paying Agent a sum sufficient to pay
the principal and any premium or interest so

                                       22

<PAGE>   27

becoming due, such sum to be held in trust for the benefit of the Persons
entitled to such principal, premium or interest, and (unless such Paying Agent
is the Trustee) the Company will promptly notify the Trustee of this action or
failure so to act.

         (c) Notwithstanding anything in this Section to the contrary, (i) the
agreement to hold sums in trust as provided in this Section is subject to the
provisions of Section 11.05, and (ii) 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 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 terms and conditions 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.

         SECTION 4.04 Appointment to Fill Vacancy in Office of Trustee.

         The Company, whenever necessary to avoid or fill a vacancy in the
office of Trustee, will appoint a Trustee, in the manner provided in Section
7.10, so that there shall at all times be a Trustee hereunder.

         SECTION 4.05      Consolidation, Merger, Conveyance of Assets.

         The Company will not, while any of the Notes remain Outstanding,
consolidate with or merge into any other Person, or sell, convey, transfer,
lease or otherwise dispose of all or substantially all of its properties and
assets to any other Person, unless each of the following shall be satisfied:

               (1)    the Person formed by such consolidation or into which the
         Company is merged, or the Person which acquires by conveyance or
         transfer or which leases all or substantially all of the properties and
         assets of the Company (any of the foregoing Persons, a "Successor")
         shall be a corporation organized and validly existing under the laws of
         the United States of America, any state thereof, or the District of
         Columbia;

               (2)    the Successor shall expressly assume, by executing an
         indenture supplemental to this Indenture (which supplemental indenture
         shall be executed and delivered to the Trustee and shall be in form
         satisfactory to the Trustee), the due and punctual payment of the
         principal of, interest and premium (if any) on all of the Notes and the
         performance of every covenant of this Indenture, as supplemented by any
         and

                                       23

<PAGE>   28

         all indentures supplemental thereto, required to be performed or
         observed on the part of the Company; and

               (3)    immediately after giving effect to such transaction, no
         Event of Default or Default shall have occurred and be continuing.

         The Trustee may require that the Company deliver an Officers'
Certificate and an Opinion of Counsel, each stating that such consolidation,
merger, conveyance, transfer or lease and the supplemental indenture required in
connection with such transaction complies with this Section 4.05 and that all
conditions precedent herein provided for relating to such transaction have been
complied with. The liabilities and obligations of the Company and the Successor
following such consolidation, merger, conveyance, transfer or lease and the
execution of the supplemental indenture required in connection therewith shall
be governed by Section 10.01.

         SECTION 4.06      Restrictions on Liens.

         (a)    The Company will not, nor will it permit any Subsidiary to,
issue, assume, guarantee or create any Debt secured by any Lien upon any
Operating Property, or upon any shares of stock or Debt of any Subsidiary
(whether such Operating Property, shares of stock or Debt is now owned or
hereafter acquired), without in such case effectively securing, concurrently
with the issuance, assumption or guaranty of any such Debt, the Notes (together
with, if the Company shall so determine, any other Debt of or guaranteed by the
Company or such Subsidiary ranking equally with the Notes and then existing or
thereafter created) equally and ratably with such Debt.

         (b)    Notwithstanding anything in this Indenture to the contrary, the
provisions of subsection (a) shall not apply to:

                   (1) Any Lien on Operating Property that is acquired,
         constructed or improved by the Company or any Subsidiary after the date
         of this Indenture, where such Lien is granted to secure Debt that is:
         (i) issued, assumed or guaranteed within 180 days after such
         acquisition, completion of construction or improvement; and (ii)
         incurred to finance such acquisition, construction or improvement.

                  (2)  Any Lien existing on any Operating Property at the time
         of the acquisition of said Operating Property by the Company or any
         Subsidiary, or any Lien on stock or Debt of any Subsidiary existing at
         the time that said Subsidiary became a Subsidiary.

         such acquisition.

                  (4)  Any Lien on any Operating Property to secure Debt of a
         Subsidiary to the Company or to another Subsidiary.

                  (5)  Any Lien in existence on the date of this Indenture.

                  (6)  Any Lien in favor of the United States of America or any
         state thereof, or any department, agency or instrumentality or
         political subdivision of the United States of America or any state
         thereof arising as a matter of law to secure payment of customs duties
         in connection with the importation of goods.

                  (7)  Any pledge or deposit in connection with workers'
         compensation, unemployment insurance and similar legislation and any
         deposit securing liability to insurance carriers under insurance or
         self-insurance arrangements.

                  (8)  Any Lien for taxes, assessments, governmental charges or
         levies not yet due or which are being contested in good faith.

                  (9)  Any Lien imposed by law, such as carrier's,
         warehousemen's, mechanic's, landlord's, materialmen's, repairmen's or
         other similar Liens.

                  (10) Any Lien securing Debt incurred to extend, renew or
         replace, in whole or in part, Debt secured by any Lien, provided that:
         (i) the principal amount of Debt secured thereby shall not exceed the
         original principal amount of the Debt so secured; and (ii) such
         extension, renewal or replacement shall be limited to all or a part of
         the property that secured the Debt so extended, renewed or replaced
         plus improvements on such property.

         (c)    In addition to the foregoing, notwithstanding the provisions of
subsection (a) and Section 4.07, the Company and its Subsidiaries may issue,
assume, guarantee or create Debt secured by a Lien upon any Operating Property
or shares of stock or Debt of any Subsidiary or enter into a Sale and Leaseback
Transaction involving any Operating Property without equally and ratably
securing the Notes if the sum of (1) the amount of the Debt secured by Liens
otherwise prohibited by subsection (a) of this Section and (2) the Attributable
Debt of all Sale and Leaseback Transactions otherwise prohibited by Section 4.07
does not exceed at the time 10% of Consolidated Net Tangible Assets.

assume, guarantee or create any Debt secured by any Lien upon any Operating
Property or shares of stock or Debt of any Subsidiary and if subsection (a) of
this Section requires that the Notes be secured equally and ratably with such
Debt, the Company will promptly execute, at its expense, any instruments
necessary to so equally and ratably secure such Notes and deliver the same to
the Trustee together with:

                   (i)    an Officers' Certificate stating that the covenant of

         of the Company has been complied with, and that any instruments
         executed by the Company in the performance of the same comply with the
         requirements of such covenant.

         (e)    If the Company shall hereafter secure the Notes equally and
ratably with any other Debt pursuant to the provisions of this Section 4.06, the
Trustee is hereby authorized to enter into an indenture or supplemental
indenture and to take such action, if any, as it may deem advisable to enable it
to enforce effectively the rights of the holders of the Notes so secured,
equally and ratably with such other Debt.

         SECTION 4.07    Limitations on Sale and Leaseback Transactions.

         Subject to the provisions of Section 4.06(c), the Company will not, nor
will it permit any Subsidiary to, enter into any Sale and Leaseback Transaction
involving any Operating Property, unless within 120 days of the effective date
of such Sale and Leaseback Transaction, the Company or such Subsidiary applies
or causes to be applied an amount equal to the greater of (i) the fair market
value of the Operating Property so sold and leased back at the time of entering
into such Sale and Leaseback Transaction (as determined by the Board of
Directors) and (ii) the net proceeds of the sale of the Operating Property sold
and leased back pursuant to such Sale and Leaseback Transaction, to:

                 (a)    the prepayment or retirement (other than mandatory
         prepayment or retirement) of Funded Debt of the Company or any
         Subsidiary, or

                 (b)    the purchase of other property that will constitute
         Operating Property.

The foregoing restriction shall not apply to a Sale and Leaseback Transaction,

                  (i)    the Company or such Subsidiary would be entitled,
         pursuant to Section 4.06(b)(1) through (10) or Section 4.06(c), to
         issue, assume or guarantee Debt in an amount equal to the Attributable
         Debt of the Sale and Leaseback Transaction secured by the Operating
         Property without being required to equally and ratably secure the
         Notes;

                  (ii)   such Sale and Leaseback Transaction is between the
         Company and a Subsidiary or between Subsidiaries; or

                  (iii)  such Sale and Leaseback Transaction involves taking
         back a lease for a period of three years or less (including renewals).

Notes, such portion of the principal amount as may be specified in the terms
thereof) of all the Notes of that Series to be due and payable immediately, and
upon any such declaration the same shall become and shall be immediately due and

         (c) At any time after the principal of the Notes of that Series shall
have been so declared due and payable, and before any judgment or decree for the
payment of the moneys due shall have been obtained or entered as hereinafter
provided, the holders of a majority in aggregate principal amount of the
Outstanding Notes of that Series, by written notice to the Company and the
Trustee, may rescind and annul such declaration and its consequences if: (i) the
Company has paid or deposited with the Trustee a sum sufficient to pay all
matured installments of interest upon all the Notes of that Series and the
principal of (and premium, if any, on) any and all Notes of that Series that
shall have become due otherwise than by acceleration (with interest upon such
principal and premium, if any, and, to the extent that such payment is
enforceable under applicable law, upon overdue installments of interest, at the
rate per annum or Yield to Maturity (in the case of Original Issue Discount
Notes) expressed in the Notes of that Series (or at the respective rates of
interest or Yields to Maturity of all the Notes, as the case may be) to the date
of such payment or deposit) and the amount payable to the Trustee under Section
7.06, and (ii) any and all Events of Default under this Indenture with respect
to such Series, other than the non-payment of principal on Notes of that Series
(or, with respect to any Notes which are Original Issue Discount Notes, such
portion of the principal as may be specified in the terms thereof) that shall
not have become due by their terms, shall have been remedied or waived as
provided in Section 6.06.

         No such rescission and annulment shall extend to or shall affect any
subsequent default or impair any right consequent thereon.

         (d) In case the Trustee shall have proceeded to enforce any right under
this Indenture and such proceedings shall have been discontinued or abandoned
because of rescission or annulment under Section 6.01(c) or for any other reason
or shall have been determined adversely to the Trustee, then and in every such
case the Company and the Trustee shall be restored respectively to their former
positions and rights hereunder, and all rights, remedies and powers of the
Company and the Trustee shall continue as though no such proceedings had been
taken.

          SECTION 6.02   Collection of Indebtedness and Suits for Enforcement by
                         Trustee.

         (a) The Company covenants that (1) in case it shall default in the
payment of any installment of interest on any of the Notes of a Series, and such
default shall have continued for a period of 30 days, or (2) in case it shall
default in the payment of the principal of (or premium, if any, on) any of the
Notes of a Series when the same shall have become due and payable, whether upon
maturity of such Notes or upon redemption or upon declaration or otherwise,
then, upon demand of the Trustee, the Company will pay to the Trustee, for the
benefit of the holders of the Notes of that Series, the whole amount that then
shall have been become due and payable on all such Notes for principal (and
premium, if any) or interest, or

                                       31

<PAGE>   36

both, as the case may be, with interest upon the overdue principal (and premium,
if any) and (to the extent that payment of such interest is enforceable under
applicable law) upon overdue installments of interest at the rate per annum or
Yield to Maturity (in the case of Original Issue Discount Notes) expressed in
the Notes of that Series; and, in addition thereto, such further amount as shall
be sufficient to cover the reasonable costs and expenses of collection, and the
amount payable to the Trustee under Section 7.06.

         (b) If the Company shall fail to pay such amounts forthwith upon such
demand, the Trustee, in its own name and as trustee of an express trust, shall
be entitled and empowered to institute any actions or proceedings at law or in
equity for the collection of the sums so due and unpaid, and may prosecute any
such action or proceeding to judgment or final decree, and may enforce any such
judgment or final decree against the Company or other obligor upon the Notes of
that Series and collect the moneys adjudged or decreed to be payable in the
manner provided by law out of the property of the Company or other obligor upon
the Notes of that Series, wherever situated.

         (c) In case of any receivership, insolvency, liquidation, bankruptcy,
reorganization, readjustment, arrangement, composition or judicial proceedings
affecting the Company, or its creditors or property, the Trustee shall have
power to intervene in such proceedings and take any action therein that may be
permitted by the court and shall (except as may be otherwise provided by law) be
entitled to file such proofs of claim and other papers and documents as may be
necessary or advisable in order to have the claims of the Trustee and of the
Noteholders allowed for the entire amount due and payable by the Company under
this Indenture at the date of institution of such proceedings and for any
additional amount that may become due and payable by the Company after such
date, and to collect and receive any moneys or other property payable or
deliverable on any such claim, and to distribute the same after the deduction of
the amount payable to the Trustee under Section 7.06; and any receiver, assignee
or trustee in bankruptcy or reorganization is hereby authorized by each of the
Noteholders to make such payments to the Trustee, and, in the event that the
Trustee shall consent to the making of such payments directly to such
Noteholders, to pay to the Trustee any amount due it under Section 7.06.

         (d) All rights of action and of asserting claims under this Indenture
or under the Notes of any Series may be enforced by the Trustee without the
possession of any of such Notes, or the production thereof at any trial or other
proceeding relative thereto, and any such suit or 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 payment to the Trustee of any
amounts due under Section 7.06, be for the ratable benefit of the Noteholders of
such Series.

                                       32

<PAGE>   37

         In case of an Event of Default hereunder, the Trustee may in its
discretion proceed to protect and enforce the rights vested in it by this
Indenture by such appropriate judicial proceedings as the Trustee shall deem
most effectual to protect and enforce any of such rights, either at law or in
equity or in bankruptcy or otherwise, whether for the specific enforcement of
any covenant or agreement contained in this Indenture or in aid of the exercise
of any power granted in this Indenture, or to enforce any other legal or
equitable right vested in the Trustee by this Indenture or by law.

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

         SECTION 6.03      Application of Moneys Collected.

         Any moneys collected by the Trustee pursuant to this Article shall be
applied in the following order, at the date or dates fixed by the Trustee and,
in case of the distribution of such moneys on account of principal (or premium,
if any) or interest, upon presentation of the Notes of the applicable Series and
notation thereon the payment if only partially paid and upon surrender thereof
if fully paid:

                  FIRST: To the payment of costs and  expenses of collection
         and of all amounts payable to the Trustee under Section 7.06; and

                  SECOND: To the payment of the amounts then due and unpaid upon
         the Outstanding Notes of such Series for principal and any premium and
         interest, in respect of which or for the benefit of which such money
         has been collected, ratably, without preference or priority of any
         kind, according to the amounts due and payable on such Outstanding
         Notes for principal and any premium and interest, respectively.

         SECTION 6.04    Limitation on Suits.

         No holder of any Note of any Series shall have any right by virtue or
by availing of any provision of this Indenture to institute any suit, action or
proceeding in equity or at law upon or under or with respect to this Indenture
or for the appointment of a receiver or trustee, or for any other remedy
hereunder, unless (i) such holder previously shall have given to the Trustee
written notice of an Event of Default and of the continuance thereof with
respect to the Notes of such Series, specifying such Event of Default, as
hereinbefore provided; (ii) the holders of not less than 25% in aggregate
principal amount of the Notes of such Series then

                                       33

<PAGE>   38

Outstanding shall have made written request upon the Trustee to institute such
action, suit or proceeding in its own name as trustee hereunder; (iii) such
holder or holders shall have offered to the Trustee such reasonable indemnity as
it may require against the costs, expenses and liabilities to be incurred
therein or thereby; and (iv) the Trustee for 60 days after its receipt of such
notice, request and offer of indemnity, shall have failed to institute any such
action, suit or proceeding; and (v) during such 60 day period, the holders of a
majority in principal amount of the Notes of such Series do not give the Trustee
a direction inconsistent with the request.

         Notwithstanding anything contained herein to the contrary, the right of
any holder of any Note of any Series to receive payment of the principal of and
any premium and (subject to Section 2.03) interest on such Note, as therein
provided, on or after the respective due dates expressed in such Note (or in the
case of redemption, on the redemption date), or to institute suit for the
enforcement of any such payment on or after such respective dates or redemption
date, shall not be impaired or affected without the consent of such holder and
by accepting a Note hereunder it is expressly understood, intended and
covenanted by the taker and holder of every Note of such Series with every other
such taker and holder and the Trustee, that no one or more holders of Notes of
any Series shall have any right in any manner whatsoever by virtue or by
availing of any provision of this Indenture to affect, disturb or prejudice the
rights of the holders of any other Notes of such Series, or to obtain or seek to
obtain priority over or preference to any other such holder, or to enforce any
right under this Indenture, except in the manner herein provided and for the
equal, ratable and common benefit of all holders of Notes of such Series. For
the protection and enforcement of the provisions of this Section, each and every
Noteholder and the Trustee shall be entitled to such relief as can be given
either at law or in equity.

         SECTION 6.05     Rights and Remedies Cumulative; Delay or Omission Not
                          Waiver.

         (a) Except as otherwise provided in Section 2.07, all powers and
remedies given by this Article to the Trustee or to the Noteholders shall, to
the extent permitted by law, be deemed cumulative and not exclusive of any other
powers and remedies available to the Trustee or the holders of the Notes, by
judicial proceedings or otherwise, to enforce the performance or observance of
the covenants and agreements contained in this Indenture or otherwise
established with respect to such Notes.

         (b) No delay or omission of the Trustee or of any holder of any of the
Notes to exercise any right or power accruing upon any Event of Default
occurring and continuing as aforesaid shall impair any such right or power, or
shall be construed to be a waiver of any such default or an acquiescence
therein; and, subject to the provisions of Section 6.04, every

                                       34

<PAGE>   39

power and remedy given by this Article or by law to the Trustee or the
Noteholders may be exercised from time to time, and as often as shall be deemed
expedient, by the Trustee or by the Noteholders.

         SECTION 6.06    Control by Noteholders.

         The holders of a majority in aggregate principal amount of the Notes of
any Series at the time Outstanding, determined in accordance with Section 8.04,
shall have the right to direct the time, method and place of conducting any
proceeding for any remedy available to the Trustee, or exercising any trust or
power conferred on the Trustee with respect to the Notes of such Series;
provided, however, that such direction shall not be in conflict with any rule of
law or with this Indenture or be unduly prejudicial to the rights of holders of
Notes of such Series not consenting; and provided, further, that the Trustee may
take any other action deemed proper by the Trustee which is not inconsistent
with such direction. Prior to the taking of any action hereunder, the Trustee
shall be entitled to reasonable indemnification satisfactory to the Trustee
against all losses and expenses caused by taking or not taking such action.
Subject to the provisions of Section 7.01, the Trustee shall have the right to
decline to follow any such direction if the Trustee in good faith shall, by a
Responsible Officer or Officers of the Trustee, determine that the proceeding so
directed would involve the Trustee in personal liability. The holders of a
majority in aggregate principal amount of the Notes of any Series at the time
Outstanding affected thereby, determined in accordance with Section 8.04, may on
behalf of the holders of all of such Notes waive any past default in the
performance of any of the covenants contained herein or in any indenture
supplemental hereto or established pursuant to Section 2.01 with respect to such
Series and its consequences, except a default in the payment of the principal of
or any premium or interest on, any of such Notes as and when the same shall
become due by the terms of such Notes otherwise than by acceleration (unless
such default has been cured and a sum sufficient to pay all matured installments
of interest and principal and any premium has been deposited with the Trustee
(in accordance with Section 6.01(c)). Upon any such waiver, the default covered
thereby shall be deemed to be cured for all purposes of this Indenture and the
Company, the Trustee and the holders of such Notes shall be restored to their
former positions and rights hereunder, respectively; but no such waiver shall
extend to any subsequent or other default or impair any right consequent
thereon.

         SECTION 6.07      Undertaking to Pay Costs.

         All parties to this Indenture agree, and each Noteholder by such
holder's acceptance of a Note shall be deemed to have agreed, that any court may
in its discretion require, in any suit for the enforcement of any right or
remedy under this Indenture, or in any suit against the Trustee for any action
taken or omitted by it as Trustee, the filing by any party litigant

                                       35

<PAGE>   40

in such suit of an undertaking to pay the costs of such suit, and that such
court may in its discretion assess reasonable costs, including reasonable
attorneys' fees, against any party litigant in such suit, having due regard to
the merits and good faith of the claims or defenses made by such party litigant;
but the provisions of this Section shall not apply to any suit instituted by the
Trustee, to any suit instituted by any Noteholder, or group of Noteholders,
holding more than 10% in aggregate principal amount of the Outstanding Notes of
any Series, or to any suit instituted by any Noteholder for the enforcement of
the payment of the principal of (or premium, if any) or interest on any Note of
any Series, on or after the due date(s) expressed in such Note or established
pursuant to this Indenture.

         SECTION 6.08    Restoration of Rights and Remedies

         If the Trustee or any holder of Notes of any Series 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 Noteholder, then and in every
such case, subject to any determination in such proceeding, the Company, the
Trustee and the holders of Notes of such Series shall be restored severally and
respectively to their former positions hereunder and thereafter all rights and
remedies of the Trustee and the holders of Notes of such Series shall continue
as though no such proceeding had been instituted.

                                  ARTICLE VII.
                             CONCERNING THE TRUSTEE

         SECTION 7.01    Certain Duties and Responsibilities of Trustee.

         (a) The Trustee, prior to the occurrence of an Event of Default with
respect to the Notes of a Series and after the curing of all Events of Default
with respect to Notes of that Series that may have occurred, shall undertake to
perform with respect to the Notes of such Series such duties and only such
duties as are specifically set forth in this Indenture and provided by the Trust
Indenture Act, and no implied covenants shall be read into this Indenture
against the Trustee. In case an Event of Default with respect to the Notes of a
Series has occurred (that has not been cured or waived), the Trustee shall
exercise such of the rights and powers vested in it by this Indenture, and use
the same degree of care and skill in their exercise, as a prudent man would
exercise or use under the circumstances in the conduct of his own affairs.

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

                                       36

<PAGE>   41

                  (1) prior to the occurrence of an Event of Default with
         respect to the Notes of a Series and after the curing or waiving of all
         Events of Default with respect to Notes of that Series that may have
         occurred:

                           (i) the duties and obligations of the Trustee with
                  respect to Notes of that Series shall be determined solely by
                  the express provisions of this Indenture, and the Trustee
                  shall not be liable with respect to Notes of that Series
                  except for the performance of such duties and obligations as
                  are specifically set forth in this Indenture, and no implied
                  covenants or obligations shall be read into this Indenture
                  against the Trustee; and

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

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

                  (3) the Trustee shall not be liable with respect to any action
         taken or omitted to be taken by it in good faith in accordance with the
         direction of the holders of not less than a majority in principal
         amount of the Notes of any Series at the time Outstanding (determined
         as provided in Section 8.04) relating to the time, method and place of
         conducting any proceeding for any remedy available to the Trustee, or
         exercising any trust or power conferred upon the Trustee under this
         Indenture with respect to Notes of that Series; and

                  (4) None of the provisions contained in this Indenture shall
         require the Trustee to expend or risk its own funds or otherwise incur
         personal financial liability in the performance of any of its duties or
         in the exercise of any of its rights or powers, if there is reasonable
         ground for believing that the repayment of such funds or liability is
         not reasonably assured to it under the terms of this Indenture or
         adequate indemnity against such risk is not reasonably assured to it.

         SECTION 7.02    Certain Rights of Trustee.

         Except as otherwise provided in Section 7.01:

         (a) 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, approval, bond, security or
other paper or document believed by it to be genuine and to have been signed or
presented by the proper party or parties;

         (b) Any request, direction, order or demand of the Company mentioned
herein shall be sufficiently evidenced by a Board Resolution or an instrument
signed in the name of the Company by the Chairman of the Board of Directors, the
Vice Chairman, the President or any Vice President and by the Secretary or an
Assistant Secretary or the Treasurer or an Assistant Treasurer thereof (unless
other evidence in respect thereof is specifically prescribed herein);

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

         (d) The Trustee shall be under no obligation to exercise any of the
rights or powers vested in it by this Indenture at the request, order or
direction of any of the Noteholders pursuant to the provisions of this
Indenture, unless such Noteholders shall have offered to the Trustee reasonable
security or indemnity against the costs, expenses and liabilities that may be
incurred therein or thereby; nothing contained herein shall, however, relieve
the Trustee of the obligation, upon the occurrence of an Event of Default with
respect to a Series of the Notes (that has not been cured or waived), to
exercise with respect to the Notes of that Series such of the rights and powers
vested in it by this Indenture, and to use the same degree of care and skill in
their exercise as a prudent man would exercise or use under the circumstances in
the conduct of his own affairs;

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

         (f) 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, consent, order, approval, bond, security, or
other papers or documents, unless requested in writing so to do by the holders
of not less than a majority in principal amount of the Outstanding Notes of the
particular Series affected thereby (determined as provided in

                                       38

<PAGE>   43

Section 8.04); provided, however, that if the payment within a reasonable time
to the Trustee of the costs, expenses or liabilities likely to be incurred by it
in the making of such investigation is, in the opinion of the Trustee, not
reasonably assured to the Trustee by the security afforded to it by the terms of
this Indenture, the Trustee may require reasonable indemnity against such costs,
expenses or liabilities as a condition to so proceeding. The reasonable expense
of every such examination shall be paid by the Company or, if paid by the
Trustee, shall be repaid by the Company upon demand; and

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

         SECTION 7.03    Trustee Not Responsible for Recitals or Indenture
                         or Notes.

         (a) The recitals contained herein and in the Notes shall be taken as
the statements of the Company, and the Trustee assumes no responsibility for the
correctness of the same.

         (b) The Trustee makes no representations as to the validity or
sufficiency of this Indenture or of the Notes.

         (c) The Trustee shall not be accountable for the use or application by
the Company of any of the Notes or of the proceeds of such Notes, or for the use
or application of any moneys paid over by the Trustee in accordance with any
provision of this Indenture or established pursuant to Section 2.01, or for the
use or application of any moneys received by any Paying Agent other than the
Trustee.

         SECTION 7.04    May Hold Notes.

         The Trustee or any Paying Agent or Registrar, in its individual or any
other capacity, may become the owner or pledgee of Notes with the same rights it
would have if it were not Trustee, Paying Agent or Registrar.

         SECTION 7.05    Moneys Held in Trust.

         Subject to the provisions of Section 11.05, all moneys received by the
Trustee shall, until used or applied as herein provided, be held in trust for
the purposes for which they were received, but need not be segregated from other
funds except to the extent required by law.

                                       39

<PAGE>   44

The Trustee shall be under no liability for interest on any moneys received by
it hereunder except such as it may agree with the Company to pay thereon.

         SECTION 7.06    Compensation and Reimbursement.

         (a) The Company covenants and agrees to pay to the Trustee, and the
Trustee shall be entitled to, such reasonable compensation (which shall not be
limited by any provision of law in regard to the compensation of a trustee of an
express trust), as the Company and the Trustee may from time to time agree in
writing, for all services rendered by it in the execution of the trusts hereby
created and in the exercise and performance of any of the powers and duties
hereunder of the Trustee, and, except as otherwise expressly provided herein,
the Company will pay or reimburse the Trustee upon its request for all
reasonable expenses, disbursements and advances incurred or made by the Trustee
in accordance with any of the provisions of this Indenture (including the
reasonable compensation and the expenses and disbursements of its counsel and of
all Persons not regularly in its employ) except any such expense, disbursement
or advance as may arise from its negligence or bad faith. The Company also
covenants to indemnify the Trustee (and its officers, agents, directors and
employees) for, and to hold it harmless against, any loss, liability or expense
incurred without negligence or bad faith on the part of the Trustee and arising
out of or in connection with the acceptance or administration of this trust,
including the reasonable costs and expenses of defending itself against any
claim of liability in the premises.

         (b) The obligations of the Company under this Section to compensate and
indemnify the Trustee and to pay or reimburse the Trustee for reasonable
expenses, disbursements and advances shall constitute additional indebtedness
hereunder. Such additional indebtedness shall be secured by a lien prior to that
of the Notes upon all property and funds held or collected by the Trustee as
such, except funds held in trust for the benefit of any Noteholders.

         SECTION 7.07    Reliance on Officers' Certificate.

         Except as otherwise provided in Section 7.01, whenever in the
administration of the provisions of this Indenture the Trustee shall deem it
necessary or desirable that a matter be proved or established prior to taking or
suffering or omitting to take any action hereunder, such matter (unless other
evidence in respect thereof be herein specifically prescribed) may, in the
absence of negligence or bad faith on the part of the Trustee, be deemed to be
conclusively proved and established by an Officers' Certificate delivered to the
Trustee and such certificate, in the absence of negligence or bad faith on the
part of the Trustee, shall be full warrant to the Trustee for any action taken,
suffered or omitted to be taken by it under the provisions of this Indenture
upon the faith thereof.

         SECTION 7.08    Disqualification; Conflicting Interests.

         If the Trustee has or shall acquire any "conflicting interest" within
the meaning of Section 310(b) of the Trust Indenture Act, the Trustee and the
Company shall in all respects comply with the provisions of Section 310(b) of
the Trust Indenture Act.

         SECTION 7.09    Corporate Trustee Required; Eligibility.

         There shall at all times be a Trustee with respect to the Notes issued
hereunder which shall at all times be a corporation organized and doing business
under the laws of the United States of America or any State or Territory thereof
or of the District of Columbia, or a corporation or other Person permitted to
act as trustee by the Commission, authorized under such laws to exercise
corporate trust powers, having a combined capital and surplus of at least
$50,000,000, and subject to supervision or examination by Federal, State,
Territorial, or District of Columbia authority. If such corporation publishes
reports of condition at least annually, pursuant to law or to the requirements
of the aforesaid supervising or examining authority, then for the purposes of
this Section, the combined capital and surplus of such corporation shall be
deemed to be its combined capital and surplus as set forth in its most recent
report of condition so published. The Company may not, nor may any Person
directly or indirectly controlling, controlled by, or under common control with
the Company, serve as Trustee. In case at any time the Trustee shall cease to be
eligible in accordance with the provisions of this Section, the Trustee shall
resign immediately in the manner and with the effect specified in Section 7.10.

         SECTION 7.10    Resignation and Removal; Appointment of Successor.

         (a) The Trustee or any successor hereafter appointed may at any time
resign by giving written notice thereof to the Company and by transmitting
notice of resignation by mail, first-class postage prepaid, to the Noteholders,
as their names and addresses appear upon the Register. Upon receiving such
notice of resignation, the Company shall promptly appoint a successor trustee by
or pursuant to a Board Resolution. If no successor trustee shall have been so
appointed and have accepted appointment within 30 days after the mailing of such
notice of resignation, the resigning Trustee may petition any court of competent
jurisdiction for the appointment of a successor trustee, or any Noteholder who
has been a bona fide holder of a Note or Notes for at least six months may on
behalf of himself and all others similarly situated, petition any such court for
the appointment of a successor trustee. Such court may thereupon, after such
notice, if any, as it may deem proper and prescribe, appoint a successor
trustee.

         (b) In case at any time any one of the following shall occur:

                                       41

<PAGE>   46

                  (1) the Trustee shall fail to comply with the provisions of
         Section 7.08 after written request therefor by the Company or by any
         Noteholder who has been a bona fide holder of a Note or Notes for at
         least six months; or

                  (2) the Trustee shall cease to be eligible in accordance with
         the provisions of Section 7.09 and shall fail to resign after written
         request therefor by the Company or by any such Noteholder; or

                  (3) the Trustee shall become incapable of acting, or shall be
         adjudged a bankrupt or insolvent, or commence a voluntary bankruptcy
         proceeding, or a receiver of the Trustee or of its property shall be
         appointed or consented to, 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, the Company may remove the Trustee and appoint a
successor trustee by or pursuant to a Board Resolution, or, unless the Trustee's
duty to resign is stayed as provided herein, any Noteholder who has been a bona
fide holder of a Note or Notes for at least six months may, on behalf of that
holder and all others similarly situated, petition any court of competent
jurisdiction for the removal of the Trustee and the appointment of a successor
trustee. Such court may thereupon, after such notice, if any, as it may deem
proper and prescribe, remove the Trustee and appoint a successor trustee.

         (c) The holders of a majority in aggregate principal amount of the
Notes at the time Outstanding may at any time remove the Trustee by so notifying
the Trustee and the Company and may appoint a successor Trustee with the consent
of the Company.

         (d) Any resignation or removal of the Trustee and appointment of a
successor trustee pursuant to any of the provisions of this Section shall become
effective upon acceptance of appointment by the successor trustee as provided in
Section 7.11.

         (e) Any successor trustee appointed pursuant to this Section shall be
appointed with respect to the Notes of all Series then Outstanding, and at any
time there shall be only one Trustee with respect to the Notes.

         SECTION 7.11    Acceptance of Appointment By Successor.

         (a) In case of the appointment hereunder of a successor trustee with
respect to all Notes, 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

                                       42

<PAGE>   47

thereupon the resignation or removal of the retiring Trustee shall become
effective and such successor trustee, without any further act, deed or
conveyance, shall become vested with all the rights, powers, trusts and duties
of the retiring Trustee; but, on the request of the Company or the successor
trustee, such retiring Trustee shall, upon payment of its charges, execute and
deliver an instrument transferring to such successor trustee all the rights,
powers, and trusts of the retiring Trustee and shall duly assign, transfer and
deliver to such successor trustee all property and money held by such retiring
Trustee hereunder.

         (b) 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 subsection (a).

         (c) 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.

         (d) Upon acceptance of appointment by a successor trustee as provided
in this Section, the Company shall transmit notice of the succession of such
trustee hereunder by mail, first-class postage prepaid, to the Noteholders, as
their names and addresses appear upon the Register. If the Company fails to
transmit such notice within ten days after acceptance of appointment by the
successor trustee, the successor trustee shall cause such notice to be
transmitted at the expense of the Company.

         SECTION 7.12    Merger, Conversion, Consolidation or Succession to
                         Business.

         Any corporation into which the Trustee may be merged or converted or
with which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to the corporate trust business of the Trustee, shall be
the successor of the Trustee hereunder, provided that such corporation shall be
qualified under the provisions of Section 7.08 and eligible under the provisions
of Section 7.09, without the execution or filing of any paper or any further act
on the part of any of the parties hereto, anything herein to the contrary
notwithstanding. In case any Notes 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 Notes so authenticated with the same effect as if such successor
Trustee had itself authenticated such Notes.

         SECTION 7.13     Preferential Collection of Claims Against the Company.

         The Trustee shall comply with Section 311(a) of the Trust Indenture
Act, excluding any creditor relationship described in Section 311(b) of the
Trust Indenture Act. A Trustee

                                       43

<PAGE>   48

who has resigned or been removed shall be subject to Section 311(a) of the Trust
Indenture Act to the extent included therein.

         SECTION 7.14    Notice of Defaults.

         If a Default occurs hereunder with respect to Notes of any Series, the
Trustee shall give the Noteholders of such Series notice of such Default as and
to the extent provided by the Trust Indenture Act; provided, however, that in
the case of any Default of the character specified in Section 6.01(a)(3) no such
notice to Noteholders shall be given until at least 30 days after the occurrence
thereof.

                                  ARTICLE VIII.
                           CONCERNING THE NOTEHOLDERS

         SECTION 8.01      Evidence of Action by Noteholders.

         Whenever in this Indenture it is provided that the holders of a
majority or specified percentage in aggregate principal amount of the Notes of a
particular Series may take any action (including the making of any demand or
request, the giving of any notice, consent or waiver or the taking of any other
action), the fact that at the time of taking any such action the holders of such
majority or specified percentage of that Series have joined therein may be
evidenced by any instrument or any number of instruments of similar tenor
executed by such holders of Notes of that Series in Person or by agent or proxy
appointed in writing. 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.

         If the Company shall solicit from the Noteholders of any Series any
request, demand, authorization, direction, notice, consent, waiver or other
action, the Company may, at its option and in the circumstances permitted by the
Trust Indenture Act, as evidenced by an Officers' Certificate, fix in advance a
record date for the determination of Noteholders entitled to give such request,
demand, authorization, direction, notice, consent, waiver or other action, but
the Company shall have no obligation to do so. If such a record date is fixed,
such request, demand, authorization, direction, notice, consent, waiver or other
action may be given before or after the record date, but only the Noteholders of
record at the close of business on the record date shall be deemed to be
Noteholders for the purposes of determining whether Noteholders of the requisite
proportion of Outstanding Notes of that Series have authorized or agreed or
consented to such request, demand, authorization, direction, notice, consent,
waiver or other action, and for that purpose the Outstanding Notes of that
Series shall be computed as of the record date; provided, however, that no such

                                       44

<PAGE>   49

authorization, agreement or consent by such Noteholders on the record date shall
be deemed effective unless it shall become effective pursuant to the provisions
of this Indenture not later than six months after the record date.

         SECTION 8.02    Proof of Execution by Noteholders.

         Subject to the provisions of Section 7.01, proof of the execution of
any instrument by a Noteholder (such proof will not require notarization) or his
agent or proxy and proof of the holding by any Person of any of the Notes shall
be sufficient if made in the following manner:

         (a) The fact and date of the execution by any such Person of any
instrument may be proved in any reasonable manner acceptable to the Trustee.

         (b) The ownership of Notes shall be proved by the Register of such
Notes or by a certificate of the Registrar thereof.

         (c) The Trustee may require such additional proof of any matter
referred to in this Section as it shall deem necessary.

         SECTION 8.03    Who May be Deemed Owners.

         Prior to the due presentment for registration of transfer of any Note,
the Company, the Trustee, any Paying Agent and any Registrar may deem and treat
the Person in whose name such Note shall be registered upon the books of the
Company as the absolute owner of such Note (whether or not such Note shall be
overdue and notwithstanding any notice of ownership or writing thereon made by
anyone other than the Registrar) for the purpose of receiving payment of or on
account of the principal of, premium, if any, and (subject to Section 2.03)
interest on such Note and for all other purposes; and neither the Company nor
the Trustee nor any Paying Agent nor any Registrar shall be affected by any
notice to the contrary.

         SECTION 8.04    Certain Notes Owned by Company Disregarded.

         In determining whether the holders of the requisite aggregate principal
amount of Notes of a particular Series have concurred in any direction, consent
of waiver under this Indenture, the Notes of that Series that are owned by the
Company or any other obligor on the Notes of that Series or by any Person
directly or indirectly controlling or controlled by or under common control with
the Company or any other obligor on the Notes of that Series shall be
disregarded and deemed not to be Outstanding for the purpose of any such

                                       45

<PAGE>   50

determination, except that for the purpose of determining whether the Trustee
shall be protected in relying on any such direction, consent or waiver, only
Notes of such Series that the Trustee actually knows are so owned shall be so
disregarded. The Notes so owned that have been pledged in good faith may be
regarded as Outstanding for the purposes of this Section if the pledgee shall
establish to the satisfaction of the Trustee the pledgee's right so to act with
respect to such Notes and that the pledgee is not a Person directly or
indirectly controlling or controlled by or under direct or indirect common
control with the Company or any such other obligor. In case of a dispute as to
such right, any decision by the Trustee taken upon the advice of counsel shall
be full protection to the Trustee.

         SECTION 8.05     Actions Binding on Future Noteholders.

         At any time prior to (but not after) the evidencing to the Trustee, as
provided in Section 8.01, of the taking of any action by the holders of the
majority or percentage in aggregate principal amount of the Notes of a
particular Series specified in this Indenture in connection with such action,
any holder of a Note of that Series that is shown by the evidence to be included
in the Notes the holders of which have consented to such action may, by filing
written notice with the Trustee, and upon proof of holding as provided in
Section 8.02, revoke such action so far as concerns such Note. Except as
aforesaid any such action taken by the holder of any Note shall be conclusive
and binding upon such holder and upon all future holders and owners of such
Note, and of any Note issued in exchange therefor, on registration of transfer
thereof or in place thereof, irrespective of whether or not any notation in
regard thereto is made upon such Note. Any action taken by the holders of the
majority or percentage in aggregate principal amount of the Notes of a
particular Series specified in this Indenture in connection with such action
shall be conclusively binding upon the Company, the Trustee and all holders of
Notes of that Series.

                                   ARTICLE IX.
                             SUPPLEMENTAL INDENTURES

         SECTION 9.01     Supplemental Indentures Without the Consent of
                          Noteholders.

         In addition to any supplemental indenture otherwise authorized by this
Indenture, the Company and the Trustee may from time to time and at any time
enter into an indenture or indentures supplemental hereto (which shall conform
to the provisions of the Trust Indenture Act as then in effect), without the
consent of the Noteholders, for one or more of the following purposes:

         (a) to cure any ambiguity, defect, or inconsistency herein or in the
Notes of any Series;

                                       46
<PAGE>   51

         (b) to comply with Article X;

         (c) to add to the covenants of the Company for the benefit of the
holders of one or more Series of Notes or to surrender any right or power herein
conferred upon the Company;

         (d) to secure the Notes pursuant to the requirements of Section 4.06;

         (e) to make any change that does not adversely affect the rights of any
Noteholder in any material respect; or

         (f) to provide for the issuance of and establish the form and terms and
conditions of the Notes of any Series as provided in Section 2.01, to establish
the form of any certifications required to be furnished pursuant to the terms of
this Indenture or any Series of Notes, or to add to the rights of the holders of
any Series of Notes.

         The Trustee is hereby authorized to join with the Company in the
execution of any such supplemental indenture, and to make any further
appropriate agreements and stipulations that may be therein contained, but the
Trustee shall not be obligated to enter into any such supplemental indenture
that affects the Trustee's own rights, duties or immunities under this Indenture
or otherwise.

         Any supplemental indenture authorized by the provisions of this Section
may be executed by the Company and the Trustee without the consent of the
holders of any of the Notes at the time Outstanding, notwithstanding any of the
provisions of Section 9.02.

         SECTION 9.02 Supplemental Indentures With Consent of Noteholders.

         With the consent (evidenced as provided in Section 8.01) of the holders
of not less than a majority in aggregate principal amount of the Notes of each
Series affected by such supplemental indenture or indentures at the time
Outstanding, the Company, when authorized by Board Resolutions, and the Trustee
may from time to time and at any time enter into an indenture or indentures
supplemental hereto (which shall conform to the provisions of the Trust
Indenture Act as then in effect) for the purpose of adding any provisions to or
changing in any manner or eliminating any of the provisions of this Indenture or
of any supplemental indenture or of modifying in any manner not covered by
Section 9.01 the rights of the holders of the Notes of such Series under this
Indenture; provided, however, that no such supplemental indenture shall, without
the consent of the holders of each Note then Outstanding affected thereby, (i)
extend the fixed maturity of any Notes of any Series, or reduce the principal
amount thereof, or reduce the rate or extend the time of payment of

                                       47

<PAGE>   52

interest thereon, or reduce any premium payable upon the redemption thereof;
(ii) reduce the amount of principal of an Original Issue Discount Note or any
other Note payable upon acceleration of the maturity thereof; (iii) change the
currency in which any Note or any premium or interest is payable; (iv) impair
the right to enforce any payment on or with respect to any Note; (v) if the
Notes are secured, change the terms and conditions pursuant to which the Notes
are secured in a manner adverse to the Noteholders; (vi) grant any preference or
priority of any Note or Series of Notes over any other Note or Series of Notes;
(vii) reduce the percentage in principal amount of outstanding Notes the consent
of whose holders is required for modification or amendment of this Indenture or
for waiver of compliance with certain provisions of this Indenture or for waiver
of certain defaults; (viii) reduce the requirements contained in this Indenture
for quorum or voting; (ix) change any obligations of the Company to maintain an
office or agency in the places and for the purposes required by the indentures;
or (x) modify any of the above provisions.

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

         SECTION 9.03      Effect of Supplemental Indentures.

         Upon the execution of any supplemental indenture pursuant to the
provisions of this Article or of Section 4.05(2), this Indenture shall be deemed
to be modified and amended in accordance therewith and the respective rights,
limitations of rights, obligations, duties and immunities under this Indenture
of the Trustee, the Company and the holders of Notes of all Series affected
thereby shall thereafter be determined, exercised and enforced hereunder subject
in all respects to such modifications and amendments, and all the terms and
conditions of any such supplemental indenture shall be and be deemed to be part
of the terms and conditions of this Indenture for any and all purposes.

         SECTION 9.04      Notes Affected by Supplemental Indentures.

         Notes of any Series, affected by a supplemental indenture,
authenticated and delivered after the execution of such supplemental indenture
pursuant to the provisions of this Article or of Section 4.05(2), may bear a
notation in form approved by the Company as to any matter provided for in such
supplemental indenture. If the Company shall so determine, new Notes of that
Series so modified as to conform, in the opinion of the Trustee and the Company,
to any modification of this Indenture contained in any such supplemental
indenture may be prepared and executed by the Company, authenticated by the
Trustee and delivered in exchange for the Notes of that Series then Outstanding.

                                       48

<PAGE>   53

         SECTION 9.05      Execution of Supplemental Indentures.

         Upon the request of the Company, accompanied by its Board Resolutions
authorizing the execution of any such supplemental indenture, and upon the
filing with the Trustee of evidence of the consent of Noteholders required to
consent thereto as aforesaid, the Trustee shall join with the Company in the
execution of such supplemental indenture unless such supplemental indenture
affects the Trustee's own rights, duties or immunities under this Indenture or
otherwise, in which case the Trustee may in its discretion but shall not be
obligated to enter into such supplemental indenture. The Trustee, subject to the
provisions of Section 7.01, may receive an Opinion of Counsel as conclusive
evidence that any supplemental indenture executed pursuant to this Article is
authorized or permitted by, and conforms to, the terms of this Article and that
it is proper for the Trustee under the provisions of this Article to join in the
execution thereof; provided, however, that such Opinion of Counsel need not be
provided in connection with the execution of a supplemental indenture that
establishes the terms of a Series of Notes pursuant to Section 2.01 hereof.

         SECTION 9.06      Conformity with Trust Indenture Act.

         Every supplemental indenture executed pursuant to this Article shall
conform to the requirements of the Trust Indenture Act of 1939, as amended, in
effect on such date.

                                   ARTICLE X.
                              SUCCESSOR CORPORATION

         SECTION 10.01     Successor Substituted.

         (a) In case of any consolidation or merger of the Company or any sale,
conveyance, transfer, lease or other disposition of all or substantially all of
the properties and assets of the Company to any other Person to the extent
permitted under Section 4.05, and upon the assumption by the successor Person,
pursuant to Section 4.05(2), by supplemental indenture, executed and delivered
to the Trustee and satisfactory in form to the Trustee, of the due and punctual
payment of the principal of and any premium and interest on all of the Notes
then Outstanding and the due and punctual performance of all of the covenants
and conditions of this Indenture and any indenture supplemental thereto, such
successor Person shall succeed to and be substituted for the Company with the
same effect as if it had been named as the Company herein, and thereupon the
predecessor Person shall be relieved of all obligations and covenants under this
Indenture and the Notes.

                                       49

<PAGE>   54

         (b) In case of any such consolidation, merger, sale, conveyance,
transfer, lease or other disposition such changes in phraseology and form (but
not in substance) may be made in the Notes thereafter to be issued as may be
appropriate.

         (c) Nothing contained in this Indenture or in any of the Notes shall
prevent the Company from entering into a merger in which it is the surviving
corporation or from acquiring by purchase or otherwise all or any part of the
property of any other Person (whether or not affiliated with the Company).

                                   ARTICLE XI.
                            DISCHARGE AND DEFEASANCE

         SECTION 11.01     Satisfaction and Discharge of Indenture.

         If at any time: (a) the Company shall have delivered to the Trustee for
cancellation all Notes of a Series theretofore authenticated (other than any
Notes that shall have been destroyed, lost or stolen and that shall have been
replaced or paid as provided in Section 2.07 and Notes for whose payment money
or Governmental Obligations have theretofore been deposited in trust or
segregated and held in trust by the Company and thereupon repaid to the Company

Notes of a particular Series not theretofore delivered to the Trustee for
cancellation shall have become due and payable, or are by their terms to become
due and payable within one year or are to be called for redemption within one
year under arrangements satisfactory to the Trustee for the giving of notice of
redemption, and the Company shall deposit or cause to be deposited with the
Trustee as trust funds an amount of money in U.S. dollars sufficient, or
non-callable Governmental Obligations, the principal of and interest on which
when due will be sufficient, or a combination thereof 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 at maturity or
upon redemption all Notes of that Series not theretofore delivered to the
Trustee for cancellation, including principal and any premium and interest due
or to become due to such date of maturity or date fixed for redemption, as the
case may be, and if the Company shall also pay or cause to be paid all other
sums payable hereunder with respect to such Series by the Company, and shall
deliver an Officer's Certificate and an Opinion of Counsel, each stating that
all conditions precedent herein provided for relating to the satisfaction and
discharge of this Indenture with respect to such Series have been complied with,
then this Indenture shall thereupon cease to be of further effect with respect
to such Series except for the provisions of Sections 2.03, 2.05, 2.07, 4.01,
4.02, 4.03, and 7.10, that shall survive until the date of maturity or
redemption date, as the case may be, and Sections 7.06 and 11.05, that shall
survive to such date and thereafter, and the Trustee, on demand of the Company
and at the cost and expense of the Company shall execute proper

instruments acknowledging satisfaction of and discharging this Indenture with
respect to such Series.

         SECTION 11.02     Defeasance and Covenant Defeasance.

         In addition to discharge of this Indenture pursuant to Section 11.01,
the Company may at its option elect at any time either to effect: (i) a
defeasance and discharge of the Notes of any particular Series under Section

Series under Section 11.02(b) below; in each case upon compliance with the

         (a) Upon election by the Company to effect a defeasance and discharge
of the Notes of any Series under this Section 11.02(a) and satisfaction of the
conditions precedent set forth in Section 11.02(c) with respect to the Notes of
such Series, the Company shall be deemed to have paid and discharged the Notes
of such Series and the Company shall be deemed to have satisfied all its other
obligations under such Notes and all its other obligations relating to such
Notes under the Indenture, except for Sections 2.03, 2.05, 2.07, 4.01, 4.02,
4.03, 7.06, 7.10 and 11.05 of this Indenture that shall survive until the Notes
of such Series mature and are paid. Thereafter, Sections 7.06 and 11.05 of this
Indenture shall survive with respect to the Notes of such Series.

         (b) Upon election by the Company to effect a covenant defeasance with
respect to the Notes of any Series under this Section 11.02(b), the Company
shall be released from its obligations under Sections 4.05, 4.06 and 4.07 of
this Indenture (if applicable to such Series) and any covenants made applicable
to the Notes of such Series which are subject to defeasance under the terms of
any indenture supplemental hereto or the terms otherwise established with
respect to such series pursuant to Section 2.01 hereof on or after the date the
conditions precedent set forth in Section 11.02(c) are satisfied (hereinafter,
"covenant defeasance"). For this purpose, such covenant defeasance means that
the Company may omit to comply with and shall have no liability in respect of
any term, condition or limitation set forth in Sections 4.05, 4.06 or 4.07 of
this Indenture (if applicable to such Series) or in any other covenant
applicable to such Series which is subject to defeasance under the terms of the
indenture supplemental hereto or the terms otherwise established with respect to
such series pursuant to Section 2.01 hereof pertaining to such Series.

         (c) The following shall be conditions precedent to the application of
either Section 11.02(a) or 11.02(b):

                  (i) the Company shall have deposited or cause to be deposited
         irrevocably with the Trustee, as trust funds in trust for the purpose
         of making the following

                                       51

         payments and specifically pledged as security for and dedicated solely
         to the benefit of the holders of the Notes to be defeased, cash in U.S.
         dollars (or such other money or currencies as shall then be legal
         tender in the United States) and/or Governmental Obligations, which
         through the scheduled payment of interest and principal in respect
         thereof, in accordance with their terms, will provide (and without
         reinvestment and assuming no tax liability will be imposed on the
         Trustee), not later than one day before the due date of any payment of
         money, an amount in cash, sufficient, in the opinion of a nationally
         recognized firm of independent certified public accountants expressed
         in a written certification thereof delivered to the Trustee, to
         discharge principal (including premium, if any) under such Notes, and
         each installment of principal (including premium, if any) and interest
         on such Notes on the stated maturity of such principal or installment
         of principal or interest on the dates on which such installments of
         principal and interest are due, in accordance with the terms of this
         Indenture, any indenture supplemental thereto entered into pursuant to
         Section 2.01 with respect to such Notes, and such Notes;

                  (ii) 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
         (which ruling may be, but need not be, issued with respect to the
         Company) or (B) since the date of this Indenture there has been a
         change in the applicable Federal income tax law, in either case to the
         effect that, and based thereon such opinion shall confirm that, the
         holders of Outstanding Notes of such Series will not recognize income,
         gain or loss for Federal income tax purposes as a result of such
         defeasance.

                  (iii) no Event of Default or Default with respect to the Notes
         to be defeased shall have occurred and be continuing on the date of
         such deposit, and no such Event of Default under Sections 6.01(a) (4)
         or (5) or event which with the giving of notice or lapse of time, or
         both, would become such an Event of Default under Sections 6.01(a)(4)
         or (5) shall have occurred and be continuing on the 91st day after such
         date or, if longer, ending on the day following the expiration of the
         longest preference period applicable to the Company in respect of such
         deposit (it being understood that this condition of this subsection
         (iii) shall not be deemed satisfied until the expiration of such
         period);

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

                  (v) the Company has delivered to the Trustee an Officers'
         Certificate and an Opinion of Counsel, each stating that all conditions
         precedent provided for relating

                                       52

<PAGE>   57

         to either the defeasance and discharge under Section 11.02(a) or the
         covenant defeasance under Section 11.02(b) (as the case may be) have
         been complied with;

                  (vi) such defeasance and discharge or covenant defeasance will
         not cause the Trustee to have a conflicting interest as defined in
         Section 7.08 or for purposes of the Trust Indenture Act with respect to
         any securities of the Company or result in the trust arising from such
         deposit to constitute an investment company under the Investment
         Company Act of 1940 or such trust shall be qualified under such act or
         exempt from regulation thereunder; and

                  (vii) the Company has paid or caused to be paid all other sums
         payable with respect to the Notes to be defeased.

         SECTION 11.03     Deposited Moneys to be Held in Trust.

         All moneys or Governmental Obligations deposited with the Trustee
pursuant to Sections 11.01 or 11.02 shall be held in trust and shall be
available for payment as due, either directly or through any Paying Agent
(including the Company acting as its own paying agent), to the holders of the
particular Series of Notes for the payment or redemption of which such moneys or
Governmental Obligations have been deposited with the Trustee.

         SECTION 11.04     Payment of Moneys Held by Paying Agents.

         In connection with the satisfaction and discharge of this Indenture all
moneys or Governmental Obligations then held by any Paying Agent under the
provisions of this Indenture shall, upon demand of the Company, be paid to the
Trustee and thereupon such Paying Agent shall be released from all further
liability with respect to such moneys or Governmental Obligations.

         SECTION 11.05     Repayment to Company.

         Any moneys or Governmental Obligations deposited with any Paying Agent
or the Trustee, or then held by the Company, in trust for payment of principal
of or premium or interest on the Notes of a particular Series that are not
applied but remain unclaimed by the holders of such Notes for at least two years
after the date upon which the principal of and any premium or interest on such
Notes shall have respectively become due and payable, shall be repaid to the
Company upon delivery to the Trustee of an Officer's Certificate, provided such
repayment is not in violation of state or federal law, and shall thereafter be
discharged from such trust; and thereupon the Paying Agent and the Trustee shall
be released from all further liability with respect to such moneys or
Governmental Obligations, and the holder of any of the Notes entitled to receive
such payment shall thereafter, as an

                                       53

<PAGE>   58

unsecured general creditor, look only to the Company for the payment thereof;
provided, however, that the Trustee or such Paying Agent, before being required
to make any such repayment, may at the expense of the Company cause to be
published once, in a newspaper published in the English language, customarily
published on each Business Day and of general circulation in the City of New
York, notice that such money remains unclaimed and that, after a date specified
therein, which shall not be less than 30 days from the date of such publication,
any unclaimed balance of such money then remaining will be repaid to the
Company.

         SECTION 11.06     Reinstatement.

         If the Trustee or the Paying Agent is unable to apply any money in
accordance with Section 11.02 by reason of any order or judgment of any court or
governmental authority enjoining, restraining, or otherwise prohibiting such
application, then the Company's obligations under the Notes to be defeased shall
be revived and reinstated as though no deposit had occurred pursuant to this
Article XI until such time as the Trustee or Paying Agent is permitted to apply
all such money in accordance with Section 11.02; provided, however, that if the
Company makes any payment of principal of (and premium, if any) or interest on
any such Notes following the reinstatement of its obligations, the Company shall
be subrogated to the rights of the holders of such Notes to receive such payment
from the money held by the Trustee or Paying Agent.

                                  ARTICLE XII.
                       IMMUNITY OF STOCKHOLDERS, OFFICERS

         SECTION 12.01     No Recourse.

         No recourse under or upon any obligation, covenant or agreement of this
Indenture, or of any Note, or for any claim based thereon or otherwise in
respect thereof, shall be had against any stockholder, officer or director,
past, present or future as such, of the Company or of any predecessor or
successor corporation, either directly or through the Company or any such
predecessor or successor corporation, whether by virtue of any constitution,
statute or rule of law, or by the enforcement of any assessment or penalty or
otherwise; it being expressly understood that this Indenture and the obligations
issued hereunder are solely corporate obligations, and that no such personal
liability whatever shall attach to, or is or shall be incurred by, the
stockholders, officers or directors as such, of the Company or of any
predecessor or successor corporation, or any of them, because of the creation of
the indebtedness hereby authorized, or under or by reason of the obligations,
covenants or agreements contained in this Indenture or in any of the Notes or
implied therefrom; and that

                                       54

<PAGE>   59

any and all such personal liability of every name and nature, either at common
law or in equity or by constitution or statute, of, and any and all such rights
and claims against, every such stockholder, officer or director as such, because
of the creation of the indebtedness hereby authorized, or under or by reason of
the obligations, covenants or agreements contained in this Indenture or in any
of the Notes or implied therefrom, are hereby expressly waived and released as a
condition of, and as a consideration for, the execution of this Indenture and
the issuance of such Notes.

                                  ARTICLE XIII.
                            MISCELLANEOUS PROVISIONS

         SECTION 13.01     Effect on Successors and Assigns.

         All the covenants, stipulations, promises and agreements in this
Indenture contained by or on behalf of the Company shall bind its successors and
assigns, whether so expressed or not.

         SECTION 13.02     Actions by Successor.

         Any act or proceeding by any provision of this Indenture authorized or
required to be done or performed by any board, committee or officer of the
Company shall and may be done and performed with like force and effect by the
corresponding board, committee or officer of any Person that shall at the time
be the lawful sole successor of the Company.

         SECTION 13.03     Notices.

         Except as otherwise expressly provided herein any notice or demand that
by any provision of this Indenture is required or permitted to be given or
served by the Trustee or by the holders of Notes to or on the Company may be
given or served by being deposited first-class postage prepaid in a post-office
letterbox addressed (until another address is filed in writing by the Company
with the Trustee) to the Company at the Corporate Office, Attention: James E.
Christenson, with copies of any notice of an Event of Default to the attention
of the Company's general counsel at the same address. Any notice, election,
request or demand by the Company or any Noteholder to or upon the Trustee shall
be deemed to have been sufficiently given or made, for all purposes, if given or
made in writing at the Trustee's Corporate Office.

         SECTION 13.04     Notice to Holders of Notes; Waiver.

         Except as otherwise expressly provided herein, where this Indenture
provides for notice to Noteholders of any event, such notice shall be
sufficiently given to Noteholders if

                                       55

<PAGE>   60

in writing and mailed, first-class postage prepaid, to each holder of a Note
affected by such event, at the address of such holder as it appears in the
Register, not earlier than the earliest date, and not later than the latest
date, prescribed for the giving of such notice.

         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 to
holders of Notes by mail, then such notification as shall be made with the
approval of the Trustee shall constitute sufficient notice to such holder for
every purpose hereunder. In any case where notice to holders of Notes is given
by mail, neither the failure to mail such notice, nor any defect in any notice
mailed to any particular holder of a Note shall affect the sufficiency of such
notice with respect to other holders of Notes given as provided herein.

         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 of Notes 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.

         SECTION 13.05     Governing Law.

         This Indenture and each Note shall be deemed to be a contract made

         (a) Upon any application or demand by the Company to the Trustee to
take any action under any of the provisions of this Indenture, the Company shall
furnish to the Trustee an Officers' Certificate stating that all conditions
precedent provided for in this Indenture relating to the proposed action have
been complied with and an Opinion of Counsel stating that in the opinion of such
counsel all such conditions precedent have been complied with, except that in
the case of any such application or demand as to which the furnishing of such
documents is specifically required by any provision of this Indenture relating
to such particular application or demand, no additional certificate or opinion
need be furnished.

                                       56

<PAGE>   61

         (b) Each certificate or opinion provided for in this Indenture and
delivered to the Trustee with respect to compliance with a condition or covenant
in this Indenture shall include (1) a statement that the Person making such
certificate or opinion has read such covenant or condition and the definitions
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
such Person, he has made such examination or investigation as is necessary to
enable him 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 or not, in
the opinion of such Person, such condition or covenant has been complied with.

         SECTION 13.08     Payments on Business Days.

         Except as provided pursuant to Section 2.01 pursuant to a Board
Resolution, and as set forth in an Officers' Certificate, or established in one
or more indentures supplemental to this Indenture, in any case where the date of
maturity of interest or principal of any Note or the date of redemption of any
Note shall not be a Business Day, then payment of interest or principal (and
premium, if any) may be made on the next succeeding Business Day with the same
force and effect as if made on the nominal date of maturity or redemption, and
no interest shall accrue for the period after such nominal date.

         SECTION 13.09     Conflict with Trust Indenture Act.

         If and to the extent that any provision of this Indenture limits,
qualifies or conflicts with a provision of the Trust Indenture Act that is
required under such Act to be a part of and to govern this Indenture, such
latter provision shall control.

         SECTION 13.10     Counterparts.

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

         SECTION 13.11     Separability.

         In case any one or more of the provisions contained in this Indenture
or in the Notes of any Series shall for any reason be held to be invalid,
illegal or unenforceable in any respect, such invalidity, illegality or
unenforceability shall not affect any other provisions of this Indenture or of
such Notes, but this Indenture and such Notes shall be construed as if such
invalid or illegal or unenforceable provision had never been contained herein or
therein.

         SECTION 13.12     Assignment.

         The Company will have the right at all times to assign any of its
rights or obligations under this Indenture to a direct or indirect wholly-owned
Subsidiary of the Company, provided that, in the event of any such assignment,
the Company will remain liable for all such obligations. Subject to the
foregoing, this Indenture is binding upon and inures to the benefit of the
parties thereto and their respective successors and assigns. This Indenture may
not otherwise be assigned by the parties thereto.

         IN WITNESS WHEREOF, the parties hereto have caused this Indenture to be
duly executed all as of the day and year first above written.
