         Effect). The Company has all requisite power and authority necessary to

incorporated therein by reference (collectively, the "Remarketing Materials") to
contain an untrue statement of a material fact or omit to state a material fact,

counsel for the Call Holder or for the Company to have a currently effective
Registration Statement and a current Prospectus in order to comply with the
requirements of the Securities Act or the Securities Act Regulations and the
Commission's interpretations of the Securities Act and the Securities Act
Regulations, or if at any time when a prospectus (or equivalent document) is
required by the Securities Act to be delivered in connection with sales of the
MVPs, any event shall occur or condition shall exist as a result of which it is
necessary, in the opinion of counsel for the Call Holder or for the Company, to
amend the Registration Statement or amend or supplement the Prospectus in order
that the Prospectus will not include any untrue statements of a material fact or
omit to state a material fact necessary in order to make the statements therein
not misleading in the light of the circumstances existing at the time it is

         satisfactory to the Call Holder, of the same tenor as the officers'
         certificate, opinion and comfort letter,

         securities dealer participating in the remarketing of the MVPs the
         opportunity to conduct an underwriter's due diligence investigation of
         the Company in a scope customarily provided in connection with a public
         offering of the Company's debt securities.

         (f) The Company agrees that neither it nor any of its subsidiaries or
affiliates shall defease, purchase or otherwise acquire, or enter into any
agreement to defease, purchase or otherwise acquire, any of the MVPs prior to
the remarketing thereof by the Call Holder, other than pursuant to Section 4(f)
or 4(g) of this Agreement.

         (g) Notwithstanding any provision to the contrary set forth in the
Senior Indenture, the Company shall (i) use its best efforts to maintain the
MVPs in book-entry form with DTC or any successor thereto and to appoint a
successor depositary to the extent necessary to maintain the MVPs in book-entry
form, and (ii) waive any discretionary right it otherwise has under the Senior
Indenture to cause the MVPs to be issued in certificated form.

         (h) To the extent that a Registration Statement and current Prospectus
are required as contemplated in paragraph (e) above, the Company shall make
representations and warranties and comply with covenants of the same tenor as
those set forth in the Underwriting Agreement, but modified to relate to the
Registration Statement and the Prospectus.

         (i) In connection with the remarketing, the Company will endeavor to
qualify the MVPs for offer and sale under the securities laws of such
jurisdictions as the Call Holder may reasonably request, provided that the
Company shall not be required to register or qualify as a foreign corporation
nor, except as to matters relating to the remarketing of the MVPs, take any
action which would subject it to service of process generally in any
jurisdiction, or to the imposition of any taxes based on, or measured by, all or
any part of the income of the Company, in any jurisdiction where it is not at
such date so subject.

         (j) During the five Business Day period ending on any remarketing date,
the Company will not, without the consent of the Call Holder, offer, sell or
contract to sell, or otherwise dispose of, directly or indirectly, or announce
the offering of, any debt securities or warrants (other than commercial paper in
the ordinary course of business during such five Business Day period in the case
of the Remarketing Date (if such date is not the Interim Period Remarketing
Date) or the Additional Remarketing Date (in the event of the Interim Period)).

         Section 4. Appointment and Obligations of the Call Holder. (a) Unless
this Agreement is otherwise terminated in accordance with Section 12 hereof, in
accordance with the terms, but subject to the conditions, of this Agreement, the
Company hereby appoints the Bank, and the Bank hereby accepts such appointment,
as the exclusive Call Holder with respect to $250,000 aggregate principal amount
of MVPs and agrees, subject to the conditions set forth herein, to 





                                       12
<PAGE>   13

remarket the MVPs, subject further to repurchase or redemption of the MVPs in
accordance with clause (f) or (g), respectively, of this section.

         (b) It is expressly understood and agreed by the parties hereto that
the obligations of the Call Holder and the Calculation Agent hereunder with
respect to the MVPs to be remarketed on the Remarketing Date and the Additional
Remarketing Date, if applicable, are conditioned on the Call Holder's election
on the Notification Date to purchase the MVPs for remarketing on the Remarketing
Date. It is further expressly understood and agreed by and between the parties
hereto that, if the Call Holder has elected to remarket the MVPs pursuant to
clause (c) below, the Call Holder shall not be obligated to remarket any MVPs or
to perform any of the other duties set forth herein at any time after the
Notification Date that (i) any of the conditions set forth in clause (a) of
Section 9 hereof shall not have been fully and completely met to the reasonable
satisfaction of the Call Holder, or (ii) any of the events set forth in clause
(b) of Section 9 hereof shall have occurred.

         (c) On a Business Day not less than five Business Days prior to the
Remarketing Date, the Call Holder shall notify the Company and the Trustee as to
whether it elects to purchase the MVPs on the Remarketing Date (the
"Notification Date"). If, and only if, the Call Holder so elects, the MVPs shall
be subject to mandatory tender to the Call Holder, and the Call Holder shall be
obligated to purchase the MVPs at a price equal to 100% of the principal amount
thereof, for remarketing on the Remarketing Date and, in the event of an Interim
Period, on the Additional Remarketing Date thereafter, subject in each case to
the conditions described herein.

         (d) Provided that the Call Holder gives notice of its intention to
purchase the MVPs in accordance with clause (c) of this section, not later than
4:00 p.m., New York City time, on the fourth Business Day prior to January 18,
2000, the Company, after consultation with the Call Holder, may notify the Call
Holder, the Trustee and DTC by telephone, confirmed in writing that it elects
January 18, 2000 to be the Interim Period Remarketing Date (the "Interim Period
Remarketing Date"). The Company will be eligible to make such notification if at
such time its senior unsecured debt is rated at least "Baa3" by Moody's
Investors Service, Inc. and "BBB-" by Standard & Poor's Ratings Services (or the
equivalent thereof by each such rating agency) at the time of such notification
or if the Call Holder waives this requirement in its sole discretion. If the
Company does not provide such notification, January 18, 2000 will be the only
remarketing ate and the Maturity Date will be January 18, 2002. If the Company
provides such notification, then (i) the Additional Remarketing Date will be one
of the 26 following one-week anniversary dates of January 18, 2000 (or if any
such day is not a Business Day, the next succeeding Business Day) designated by
the Company not later than the fifth Business Day prior to such one-week
anniversary date (the "Additional Remarketing Date") except that, if the Company
fails to so designate the Additional Remarketing Date, the Additional
Remarketing Date will be the date that is the 26th week anniversary of January
18, 2000 (or if such day is not a Business Day, the next following Business Day)
and (ii) the Maturity Date of the MVPs will be the date that is the two-year
anniversary of the Additional Remarketing Date (whether or not a Business Day).





                                       13
<PAGE>   14

         (e) In the event that the MVPs are remarketed as provided herein, the
Call Holder shall make, or cause the Trustee to make, payment to the DTC
Participant of each tendering Beneficial Owner of MVPs subject to remarketing,
by book entry through DTC by the deadline on the applicable remarketing date
then in effect under DTC's rules and regulations against delivery through DTC of
such Beneficial Owner's tendered MVPs, of 100% of the principal amount of the
tendered MVPs that have been purchased for remarketing by the Call Holder. The
Company shall make, or cause the Trustee to make, payment of interest to each
Beneficial Owner of MVPs due on the applicable remarketing date by book entry
through DTC by the close of business on such remarketing date.

         (f) Subject to Section 12(c) of this Agreement, in the event that (i)
the Calculation Agent for any reason does not notify the Company of (A) the
Interest Rate to Maturity by 4:00 p.m., New York City time, on the Determination
Date or (B) in the event of the Interim Period, the Interim Period Interest Rate
which will initially be in effect, by 4:00 p.m. on the second Business Day prior
to January 18, 2000, or (ii) prior to any remarketing date, the Call Holder has
resigned and no successor has been appointed (A) on or before the Determination
Date or, (B) in the event of the Interim Period, the second Business Day prior
to January 18, 2000, or (iii) at any time after the Call Holder elects on the
Notification Date to remarket the MVPs any event as set forth in Section 9 or
Section 12 of this Agreement shall have occurred, or (iv) the Call Holder for
any reason does not elect to purchase the MVPs for remarketing on the
Remarketing Date, or (v) the Call Holder for any reason does not purchase all
tendered MVPs on any remarketing date, or (vi) a Reference Corporate Dealer
shall fail to purchase all of the MVPs from the Call Holder on the Remarketing
Date (if such date is not the Interim Period Remarketing Date) or the Additional
Remarketing Date (in the event of the Interim Period), or (vii) in the event of
the Interim Period, a Reference Money Market Dealer shall fail to purchase all
of the MVPs on the Interim Period Remarketing Date, then the Company shall
repurchase the MVPs as a whole on the remarketing date relating to such event
(which, in the case of the event described in clause (iii) that occurs during
the Interim Period shall be the Additional Remarketing Date) at a price equal to
100% of the principal amount of the MVPs plus all accrued and unpaid interest,
if any, on the MVPs to such remarketing date. In any such case, payment will be
made by the Company through the Trustee to the DTC Participant of each tendering
Beneficial Owner of MVPs, by book-entry through DTC by the close of business on
the applicable remarketing date against delivery through DTC of such Beneficial
Owner's tendered MVPs.

         (g) If the Call Holder elects to remarket the MVPs as provided in
clause (c) above, then not later than the fourth Business Day immediately
preceding the Remarketing Date or the Additional Remarketing Date, if any, the
Company may notify the Call Holder and the Trustee if the Company irrevocably
elects to exercise its right to redeem the MVPs, in whole but not in part, from
the Call Holder on the remarketing date immediately following such notification
at the Optional Redemption Price. If the Company elects to redeem the MVPs, it
shall pay the Optional Redemption Price therefor in same-day funds on such
remarketing date by wire transfer to an account designated by the Call Holder.



                                       14
<PAGE>   15

         (h) On the Determination Date, the Call Holder shall enter into a
binding contract to sell the MVPs to the Reference Corporate Dealer that
provided the lowest bid for settlement on the Remarketing Date (if such date is
not the Interim Period Remarketing Date) or the Additional Remarketing Date (in
the event of an Interim Period). In addition, on the third business day
preceding the Interim Period Remarketing Date, the Call Holder shall enter into
a binding contract to sell the MVPs to the Reference Money Market Dealer that
provided the lowest bid for settlement on the Interim Period Remarketing Date.
In either case, however, if FCCM does not provide the lowest of such bids, FCCM
may match the lowest of such bids and, thereupon, the Call Holder shall enter
into a binding contract to sell the MVPs to FCCM. Likewise, in either case, in
the event that more than one equal bid is received, the Call Holder shall select
the purchasing Reference Corporate Dealer or Reference Money Market Dealer, as
the case may be, at its discretion. The winning bidder will bear all of its own
expenses in connection with the remarketing. In the event that such Reference
Corporate Dealer or Reference Money Market Dealer fails to purchase the MVPs on
the applicable remarketing date for any reason, all of the obligations of the
Call Holder hereunder, including any obligation to purchase and remarket the
MVPs on such remarketing date, shall be terminated.

         (i) The Call Holder may, without the consent of the Holders and
Beneficial Owners, modify the tender and settlement procedures set forth in the
Senior Indenture in order to facilitate the tender and settlement process; and
if requested by the Call Holder, the Company shall cooperate with the Call
Holder to effect such modification and enforce, for the benefit of the Call
Holder, compliance by the Holders and Beneficial Owners of the MVPs with the
terms of the MVPs relating to the purchase rights of the Call Holder.

         (j) The tender and settlement procedures described above, including
provisions for payment by purchasers of MVPs in the remarketing or for payment
to Beneficial Owners of tendered MVPs, may be modified to the extent required by
DTC or, if agreed to by the Call Holder in accordance with Section 9(b)(viii) of
this Agreement, to the extent required to facilitate the tender and remarketing
of MVPs in certificated form, if the book-entry system is no longer available
for the MVPs at the time of the remarketing.

         Section 5. Appointment and Obligations of the Calculation Agent. (a)
Unless this Agreement is otherwise terminated in accordance with Section 12
hereof, in accordance with the terms, but subject to the conditions, of this
Agreement, the Company hereby appoints FCCM, and FCCM hereby accepts such
appointment, as the exclusive Calculation Agent with respect to the MVPs. All
determinations provided for below, other than the Applicable Spread, shall be
made in good faith by the Calculation Agent.

         (b) Subject to the Call Holder's election to remarket the MVPs as
provided in clause (c) of Section 4 hereof and to the termination provisions
provided in Section 12(b) hereof, from and including the Remarketing Date (if
such date is not the Interim Period Remarketing Date) or the Additional
Remarketing Date (in the event of an Interim Period), the MVPs shall bear
interest at the Interest Rate to Maturity. During the Interim Period, if any,
the MVPs shall bear interest at the Interim Period Interest Rate.





                                       15
<PAGE>   16

                           (i) The Interest Rate to Maturity shall be determined
         by the Calculation Agent by 3:30 p.m., New York City time, on the
         Determination Date to the nearest one hundred-thousandth (0.00001) of
         one percent per annum by soliciting firm committed bids, expressed as a
         spread over the Base Rate, to purchase all outstanding MVPs at the
         Dollar Price, and by selecting the lowest such firm committed bid
         (regardless of whether each of the Reference Corporate Dealers actually
         submits bids). The Interest Rate to Maturity will be equal to the sum
         of the Base Rate plus the Applicable Spread. The Interest Rate to
         Maturity announced by the Calculation Agent, absent manifest error,
         shall be binding and conclusive upon the Beneficial Owners and Holders
         of the MVPs, the Call Holder, the Company and the Trustee.

                           (ii) The interest rate for the Interim Period, if
         any, will be reset on each Interest Reset Date during the Interim
         Period and will be equal to the Reference Rate in respect of the
         applicable Interest Reset Date plus the Basic Spread, in each case as
         calculated by the Calculation Agent (the "Interim Period Interest
         Rate"). The Wednesday of each week during the Interim Period will be an
         "Interest Reset Date." The "Interest Determination Date" applicable to
         an Interest Reset Date will be the second Business Day preceding such
         Interest Reset Date. The interest rate in effect from and including the
         Interim Period Remarketing Date (which is the first day of the Interim
         Period) to but excluding the first Interest Reset Date during such
         Interim Period will be determined as if the Interim Period Remarketing
         Date were an Interest Reset Date and the Interest Determination Date
         for such Interest Reset Date were the second Business Day prior to the
         Interim Period Remarketing Date. The Interim Period Interest Rate and
         the amount of interest payable on the Additional Remarketing Date shall
         each be determined by the Calculation Agent and, absent manifest error,
         shall be binding and conclusive upon the Beneficial Owners and Holders
         of the MVPs, the Call Holder, the Company and the Trustee.

         (c) Subject to the Call Holder's election to remarket the MVPs as
provided in Section 4(c), the Calculation Agent shall notify the Trustee and DTC
by telephone, confirmed in writing (which may include facsimile or other
electronic transmission), by 4:00 p.m., New York City time, on the Determination
Date of the Interest Rate to Maturity applicable to the MVPs effective from and
including the Remarketing Date (if such date has not been designated as the
Interim Period Remarketing Date) or Additional Remarketing Date (in the event of
an Interim Period). In the event of an Interim Period, the Calculation Agent
shall provide the Company, the Trustee and DTC notice in accordance with the
preceding sentence, on the second Business Day prior to the Interim Period
Remarketing Date of the Interim Period Interest Rate which will initially be in
effect.

         (d) It is expressly understood and agreed by the parties hereto that
the obligations of the Calculation Agent hereunder with respect to the MVPs to
be remarketed are conditioned on the Call Holder's election on the Notification
Date to purchase the MVPs for remarketing. It is further expressly understood
and agreed by and between the parties hereto that, if the Call Holder has
elected to remarket the MVPs pursuant to clause (c) of Section 4 hereof, the
Calculation 




                                       16
<PAGE>   17

Agent shall not be obligated to perform any of the duties set forth herein at
any time after the Notification Date that (i) any of the conditions set forth in
clause (a) of Section 9 hereof shall not have been fully and completely met to
the reasonable satisfaction of the Call Holder, or (ii) any of the events set
forth in clause (b) of Section 9 hereof shall have occurred.

         Section 6. Fees and Expenses. Subject to Section 12 of this Agreement,
for its services in performing its duties set forth herein, each of the Call
Holder and the Calculation Agent will not receive any fees or reimbursement of
expenses from the Company.

         Section 7. Resignation of the Call Holder and Calculation Agent. Each
of the Call Holder and the Calculation Agent may resign and be discharged from
its duties and obligations hereunder at any time, such resignation to be
effective 10 days after delivery of a written notice to the Company and the
Trustee of such resignation, provided that no such resignation shall occur under
this sentence after the Notification Date. Each of the Call Holder and the
Calculation Agent also may resign and be discharged from its duties and
obligations hereunder at any time, such resignation to be effective immediately,
upon termination of this Agreement in accordance with Section 12(b) hereof. The
Company shall have the right, but not the obligation, to appoint a successor
Call Holder; provided, however, that the Call Holder may appoint a successor
Calculation Agent in the event of the resignation of the Calculation Agent in
the absence of a concurrent resignation of the Call Holder.

         Section 8. Dealing in the MVPs; Purchase of MVPs by the Company. (a)
The Bank, or FCCM in their individual or any other capacity, may, to the extent
permitted by law, buy, sell, hold and deal in any of the MVPs. The Bank, as
Holder or Beneficial Owner of the MVPs, may exercise any vote or join as a
Holder or Beneficial Owner, as the case may be, in any action which any Holder
or Beneficial Owner of MVPs may be entitled to exercise or take pursuant to the
Senior Indenture with like effect as if it did not act in any capacity
hereunder. The Call Holder and the Calculation Agent, in their respective
capacities as either principal or agent, may also engage in or have an interest
in any financial or other transaction with the Company as freely as if they did
not act in any capacity hereunder.

         (b) The Company or its affiliates may purchase MVPs in the remarketing
on the Remarketing Date (if such date is not the Interim Period Remarketing
Date) or the Additional Remarketing Date (in the event of the Interim Period),
provided that the Interest Rate to Maturity established with respect to MVPs is
not different from the interest rate that would have been established if the
Company or its affiliates had not purchased such MVPs. In accordance with
Section 3(f) hereof, under no circumstances may the Company purchase MVPs in the
remarketing on the Interim Period Remarketing Date.

         Section 9. Conditions to Call Holder's Obligations. The obligations of
the Call Holder under this Agreement have been undertaken in reliance on, and
shall be subject to, (a) the due performance in all material respects by the
Company of its obligations and agreements as set forth in this Agreement and the
accuracy in all material respects as of the dates specified herein of the
representations and warranties in this Agreement and any certificate delivered
pursuant hereto, and (b) the further condition that none of the following events
shall have occurred at any




                                       17
<PAGE>   18

time since the date hereof (provided, that with respect to termination of the
Call Holder's obligations hereunder after the Call Holder elects on the
Notification Date to remarket the MVPs due to events that occur or arise prior
to the Call Holder's election on the Notification Date to remarket the MVPs,
only to the extent that, in the reasonable judgment of the Call Holder, the
effect thereof is to make it illegal or commercially impractical for the Call
Holder to remarket the MVPs on the applicable remarketing date):

                           (i) the rating of any securities of the Company shall
         have been down-graded or put under surveillance or review, including
         being put on CreditWatch or Watch List with negative implications, or
         withdrawn by a nationally recognized statistical rating agency;

                           (ii) without the prior written consent of the Call
         Holder, the Senior Indenture (including the MVPs) shall have been
         amended in any manner, or otherwise contain any provision not contained
         therein as of the date hereof, that in either case in the reasonable
         judgment of the Call Holder materially changes the nature of the MVPs
         or the remarketing procedures (it being understood that,
         notwithstanding the provisions of this clause (ii), the Company shall
         not be prohibited from amending the Senior Indenture);

                           (iii) (A) trading in any securities of the Company
         shall have been suspended or materially limited by the Commission or
         the New York Stock Exchange, or (B) if trading generally on the
         American Stock Exchange or the New York Stock Exchange or in the Nasdaq
         National Market shall have been suspended or materially limited, or (C)
         minimum or maximum prices for trading shall have been fixed, or maximum
         ranges for prices shall have been required, by any of said exchanges or
         by such system or by order of the Commission, the National Association
         of Securities Dealers, Inc. or any other governmental authority, or (D)
         if a banking moratorium shall have been declared by either Federal or
         New York authorities;

                           (iv) there shall have occurred any material adverse
         change in the financial markets in the United States or the
         international financial markets, any outbreak of hostilities or
         escalation thereof or other calamity or crisis or any change or
         development involving a prospective change in national or international
         political, financial or economic conditions, in each case the effect of
         which is such as to make it, in the reasonable judgment of the Call
         Holder, impracticable to remarket the MVPs or to enforce contracts for
         the sale of the MVPs;

                           (v) an Event of Default (as defined in the Senior
         Indenture), or any event which, with the giving of notice or passage of
         time, or both, would constitute an Event of Default, with respect to
         the MVPs shall have occurred and be continuing;

                           (vi) a material adverse change, or any development
         involving a prospective material adverse change, in the financial
         condition, results of operations, business or properties of the Company
         and its subsidiaries taken as a whole whether or not arising in the
         ordinary course of business, shall have occurred which has a material





                                       18
<PAGE>   19

         adverse effect on the investment quality of the MVPs or which, in the
         reasonable judgment of the Call Holder, has had or may have materially
         adverse consequences for the Company or which makes it impractical or
         inadvisable, in the reasonable judgment of the Call Holder, to proceed
         with the remarketing or the delivery of the MVPs;

                           (vii) if the Prospectus is required under the
         Securities Act to be delivered in connection with any remarketing of
         the MVPs, the Company shall fail to furnish to the Call Holder on the
         Remarketing Date and, in the event of the Interim Period, on the
         Additional Remarketing Date the officers' certificate, opinion and
         comfort letter referred to in Section 3(e) of this Agreement and such
         other documents and opinions as counsel for the Call Holder may
         reasonably require for the purpose of enabling such counsel to pass
         upon the sale of MVPs in the remarketing as herein contemplated and
         related proceedings, or in order to evidence the accuracy and
         completeness of any of the representations and warranties, or the
         fulfillment of any of the conditions, herein contained;

                           (viii) the MVPs are not maintained in book-entry form
         with DTC or any successor thereto; provided, that the Call Holder,
         subject to receipt of an opinion of counsel for the Company reasonably
         satisfactory to the Call Holder, shall waive the foregoing condition if
         in the Call Holder's reasonable judgment (x) the Senior Indenture and
         the MVPs can be amended, and they are amended, so as to permit the
         remarketing of the MVPs in certificated form and (y) it is practical to
         remarket the MVPs with the same effect and on the same terms as
         otherwise contemplated herein;

                           (ix) the Treasury Rate used to determine the Dollar
         Price on the third Business Day prior to the Remarketing Date exceeds
         the Base Rate; or

                           (x) the Calculation Agent shall not have received by
         the required time on the Remarketing Date or the Additional Remarketing
         Date, if applicable, any firm committed bids to purchase all of the
         MVPs; or

                           (xi) a Reference Corporate Dealer shall fail to
         purchase the MVPs from the Call Holder on the Remarketing Date or the
         Additional Remarketing Date (in the event of the Interim Period);

and the Call Holder shall have received on the Remarketing Date and the
Additional Remarketing Date (in the event of an Interim Period) a certificate of
the Chairman of the Board or the President or a Vice President and the chief
financial officer of the Company, dated as of the applicable remarketing date to
the effect that (i) the representations and warranties in this Agreement are
true and correct with the same force and effect as though expressly made at and
as of the applicable remarketing date, (ii) the Company has complied in all
material respects with all agreements and satisfied all conditions on its part
to be performed or satisfied at or prior to the applicable remarketing date, and
(iii) none of the events specified in the preceding clauses (b)(i) through
(viii) has occurred.





                                       19

         (c) In furtherance of the foregoing, the effectiveness of the Call
Holder's election on the Notification Date to remarket the MVPs shall be subject
to the condition that the Call Holder shall have received a certificate of the
Chairman of the Board or the President or a Vice President and the chief
financial officer of the Company, dated as of the Notification Date, to the
effect that (i) the Company has, prior to the Call Holder's election on the
Notification Date to remarket the MVPs, provided the Call Holder with notice of
all events as required under Section 3(a) of this Agreement, (ii) the
representations and warranties in this Agreement are true and correct at and as
of the Notification Date and (iii) the Company has complied in all material
respects with all agreements and satisfied all conditions on its part to be
performed or satisfied at or prior to the Notification Date. Such certificate
shall be delivered by the Company to the Call Holder as soon as practicable
following notification by the Call Holder to the Company on the Notification
Date of its election to remarket the MVPs and in any event prior to the third
Business Day prior to the Remarketing Date.

         In the event of the failure of any of the foregoing conditions, the
Call Holder may terminate its obligations under this Agreement or redetermine
the Interest Rate to Maturity as provided in Section 12 hereof.

         Section 10. Indemnification. (a) The Company shall indemnify and hold
harmless the Call Holder and its officers, directors and employees and each
person, if any, who controls the Call Holder within the meaning of Section 20 of
the Exchange Act against any and all losses, claims, damages or liabilities,
joint or several, to which they or any of them may become subject, as incurred,
insofar as such losses, claims, damages or liabilities (or actions in respect
thereof) arise out of or are based upon, (i) the failure to have an effective
registration statement under the Securities Act relating to the MVPs, if
required, or the failure to satisfy the prospectus delivery requirements of the
Securities Act because the Company failed to notify the Call Holder of such
delivery requirement or failed to provide the Call Holder with an updated
Prospectus for delivery, or (ii) any untrue statement or alleged untrue
statement of a material fact contained in any of the Remarketing Materials
(including any incorporated documents), or (iii) the omission or alleged
omission therefrom of a material fact necessary to make the statements therein,
in the light of the circumstances in which they were made, not misleading, or
(iv) any violation by the Company of, or any failure by the Company to perform
any of its obligations under, this Agreement, or (v) the acts or omissions of
the Calculation Agent in connection with its duties and obligations hereunder
except that are finally judicially determined to be due to its gross negligence
or willful misconduct, and reimburse each such indemnified party upon demand for
any legal or other expenses reasonably incurred by it in connection with
investigating or defending any such loss, claim, damage, liability or action and
shall, if requested by any such indemnified party, assume the defense of such
indemnified party in any action based upon allegations of any such loss, claim,
damage or liability, with counsel satisfactory to such indemnified party;
provided, however, that the Company will not be liable in any such case to the
extent that any such loss, claim, damage or liability arises out of or is based
upon any such untrue statement or alleged untrue statement or omission or
alleged omission made therein in reliance upon and in conformity with written
information furnished to the Company by or on behalf of the Call Holder
expressly for use in connection with the preparation of the Remarketing





                                       20
<PAGE>   21

Materials. This indemnity agreement will be in addition to any liability which
the Company may otherwise have.

         (b) The Call Holder shall indemnify and hold harmless the Company, each
of its directors, each of its officers who has signed the Registration Statement
and each person, if any, who controls the Company within the meaning of Section
20 of the Exchange Act against any and all losses, claims, damages or
liabilities, joint or several, to which they or any of them may become subject,
as incurred, insofar as such losses, claims, damages or liabilities (or actions
in respect thereof) arise out of or are based upon any untrue statement or
alleged untrue statement of a material fact contained in the Remarketing
Materials, or the omission or alleged omission to state therein a material fact
required to be stated therein or necessary to make the statements therein not
misleading, in each case to the extent, but only to the extent, that the same
was made therein in reliance upon and in conformity with written information
furnished to the Company by or on behalf of the Call Holder specifically for use
in connection with the preparation of the Remarketing Materials, and reimburse
each such indemnified party upon demand for any legal or other expenses
reasonably incurred by it in connection with investigating or defending any such
loss, claim, damage, liability or action. This indemnity agreement will be in
addition to any liability which the Call Holder may otherwise have.

         (c) Promptly after receipt by an indemnified party under this Section
10 of notice of the commencement of any action, such indemnified party will, if
a claim in respect thereof is to be made against the indemnifying party under
this Section 10, notify the indemnifying party in writing of the commencement of
such action in sufficient time to permit the indemnifying party to assume the
defense thereof, but the omission so to notify the indemnifying party will not
relieve it from any liability which it may have to any indemnified party
otherwise than under this Section 10. In case any such action is brought against
any indemnified party, and it notifies the indemnifying party of the
commencement thereof, the indemnifying party will (i) if it is so required under
subparagraph (a) of this Paragraph, assume the defense of such action with
counsel satisfactory to such indemnified party, or (ii) if not required to
assume the defense under such paragraph (a), will be entitled to participate
therein, and to the extent that it may elect by written notice delivered to the
indemnified party promptly after receiving the aforesaid notice from such
indemnified party, to assume the defense thereof with counsel satisfactory to
such indemnified party; provided, however, if the defendants in any such action
include both the indemnified party and the indemnifying party, and the
indemnified party shall have reasonably concluded that there may be legal
defenses available to it and/or other indemnified parties which are different
from or additional to those available to the indemnifying party, the indemnified
party or parties shall have the right to select separate counsel to assert such
legal defenses (in which case the indemnifying party shall not have the right to
direct the defense of such action on behalf of the indemnified party or
parties), but the indemnifying party shall not, in connection with any one such
action, or separate but substantially similar or related actions in the same
jurisdiction arising out of the same general allegations or circumstances, be
liable for the fees and expenses with respect to any period during the pendency
of such action or similar or related actions of more than one separate firm of
attorneys for all indemnified parties so named, designated in writing by the
Call Holder if the indemnifying party is the Company or by the




                                       21
<PAGE>   22

Company if the indemnifying party is the Call Holder. Upon the assumption by the
indemnifying party of the defense of such action pursuant to clause (i) or
clause (ii) of this subparagraph (c), and approval by the indemnified party of
counsel, the indemnifying party shall not be liable to such indemnified party
under this Section 10 for any legal or other expenses subsequently incurred by
such indemnified party in connection with the defense thereof (other than
reasonable costs of investigation) unless (x) the indemnified party shall have
employed separate counsel in connection with the assertion of legal defenses in
accordance with the proviso to the next preceding sentence, (y) the indemnifying
party shall not have employed counsel satisfactory to the indemnified party to
represent the indemnified party within a reasonable time, or (z) the
indemnifying party has authorized the employment of counsel for the indemnified
party at the expense of the indemnifying party. The indemnifying party shall not
be liable for any settlement of any action or claim effected without its consent
which consent shall not be unreasonably withheld.

         (d) The respective indemnity and contribution agreements of the Company
and the Call Holder contained in this Section 10 and Section 11, and the
representations and warranties of the Company contained in Section 2 hereof,
shall remain operative and in full force and effect, regardless of any
termination or cancellation of this Agreement or any investigation made by or on
behalf of the Call Holder or the Company or any director or officer or any
controlling person referred to in this Section 10, and such agreement,
representations and warranties, as well as the other covenants contained herein,
shall survive any remarketing of the MVPs and any successor of the Call Holder
or of the Company or any legal representative of any such director or officer or
of any such controlling person, as the case may be, shall be entitled to the
benefits of the respective indemnity and contribution agreements.

         Section 11. Contribution. In order to provide for just and equitable
contribution in circumstances in which the indemnification provided for in
subparagraph (a) or (b) of Section 10 is for any reason held to be unavailable
from an indemnifying party, then the Company and the Call Holder shall
contribute to the aggregate losses, claims, damages and liabilities (including
any investigation, legal and other expenses incurred in connection with, and any
amount paid in settlement of, any action, suit or proceeding or any claims
asserted) to which the Company and the Call Holder may be subject in such
proportion so that the Call Holder is responsible for that portion represented
by the percentage that the aggregate positive difference, if any, between the
price paid by the Call Holder for the MVPs (the "Aggregate Positive Difference")
tendered on the Remarketing Date or the Additional Remarketing Date, as the case
may be, and the price at which MVPs bearing the Interest Rate to Maturity are
sold by the Call Holder bears to the aggregate principal amount of the MVPs, and
the Company is responsible for the balance; provided, however, that (y) in no
case shall the Call Holder be responsible for any amount in excess of the
Aggregate Positive Difference and (z) no person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation. For purposes of this Section 11, each person, if
any, who controls the Call Holder within the meaning Section 20 of the Exchange
Act shall have the same rights to contribution as the Call Holder, and each
person, if any, who controls the Company within the meaning of Section 20 of the





                                       22
<PAGE>   23

Exchange Act, each officer of the Company who shall have signed the Registration
Statement and each director of the Company shall have the same rights to
contribution as the Company, subject in each case to clauses (y) and (z) of this
Section 11. Any party entitled to contribution will, promptly after receipt of
notice of commencement of any action, suit or proceeding against such party in
respect of which a claim for contribution may be made against another party or
parties under this Section 11, notify such party or parties from whom
contribution may be sought, but the omission so to notify such party or parties
shall not relieve the party or parties from whom contribution may be sought from
any other obligation it or they may have hereunder or otherwise than under this
Section 11.



         Section 12. Termination of Remarketing and Interest Calculation
Agreement or Redetermination of Interest Rate to Maturity. (a) This Agreement
shall terminate as to the Call Holder on the effective date of the resignation
of the Call Holder pursuant to Section 7 hereof or if the Call Holder does not
elect to remarket the MVPs pursuant to Section 4(c) hereof, or upon the
notification of the Call Holder by the Company of its election to redeem the
MVPs pursuant to Section 4(g) hereof.

         (b) In addition, the Call Holder may terminate all of its obligations
under this Agreement immediately by notifying the Company and the Trustee of its
election to do so, at any time on or before the Remarketing Date (if such date
is not the Interim Period Remarketing Date) or the Additional Remarketing Date
(in the event of the Interim Period), in the event that: (i) any of the
conditions referred to or set forth in Section 9 (a) hereof have not been met or
satisfied in full, (ii) any of the events set forth in Section 9(b) hereof shall
have occurred, or (iii) the Call Holder determines, in its discretion, after
consultation with the Company, that it shall not have received all of the
information, whether or not specifically referenced herein, reasonably necessary
to remarket the MVPs under this Agreement.

         (c) Notwithstanding any provision herein to the contrary, in lieu of
terminating this Agreement pursuant to Section 12(b) above, upon the occurrence
of any of the events set forth therein, the Call Holder, in its sole discretion
at any time between the Determination Date and 3:30 p.m., New York City time, on
the Business Day immediately preceding the Remarketing Date (if such date is not
the Interim Period Remarketing Date) or the Additional Remarketing Date (in the
event of the Interim Period), may elect to purchase the MVPs for remarketing and
cause the Calculation Agent to determine a new Interest Rate to Maturity in the
manner provided in Section 5(b) of this Agreement, except that for purposes of
determining the new Interest Rate to Maturity pursuant to this paragraph, the
Determination Date referred to therein shall be the date of such election and
redetermination of the Interest Rate to Maturity. The Calculation Agent shall
notify the Company, the Trustee and DTC by telephone, confirmed in writing
(which may include facsimile or other electronic transmission), by 4:00 p.m.,
New York City time, on the date of such election, of the new Interest Rate to
Maturity applicable to the MVPs. Thereupon, such new Interest Rate to Maturity
shall supersede and replace any Interest Rate to Maturity previously determined
by the Calculation Agent and, absent manifest error, shall be 




                                       23
<PAGE>   24

binding and conclusive upon the Beneficial Owners and Holders of the MVPs on or
after the Remarketing Date or Additional Remarketing Date, as the case may be,
the Company and the Trustee; provided, however, that the Call Holder, by
redetermining the Interest Rate to Maturity upon the occurrence of any event set
forth in Section 12(b) hereof as set forth above, shall not thereby be deemed to
have waived its right to determine a new Interest Rate to Maturity or terminate
this Agreement upon the occurrence of any other event set forth in Section 12(b)
hereof.

         (d) If this Agreement is terminated pursuant to this Section, such
termination shall be without liability of any party to any other party, except
that, in the case of termination pursuant to Section 12(b) of this Agreement,
the Company shall reimburse the Call Holder for all of its out-of-pocket
expenses, including the reasonable fees and disbursements of counsel for the
Call Holder in connection with the remarketing, and except further as set forth
in Section 12(e) below. Sections 1, 10, 11, 12(d) and 12(e) hereof shall survive
such termination and remain in full force and effect.

         (e) In the case of either (A) termination of this Agreement pursuant to
Section 12(b) hereof after the Call Holder's election on the Notification Date
to remarket the MVPs, or (B) the occurrence, prior to the Call Holder's election
on the Notification Date to remarket the MVPs, of any event set forth in Section
9(b)(ii), (v) or (viii) hereof, upon the request of the Call Holder, the
Company, in each case, shall immediately following the Call Price Determination
Date pay the Call Holder, in same-day funds by wire transfer to an account
designated by the Call Holder, the fair market value, calculated as set forth
below, of the Call Holder's embedded interest rate option implicit in the Call
Holder's right to purchase and remarket the MVPs pursuant to this Agreement (the
"Call Price"). Payment of the Call Price, in any case, shall be made by the
Company within five Business Days of the Call Holder's request pursuant to this
paragraph.

                  (i) In the case of termination of this Agreement pursuant to
         Section 12(b) hereof on or after the Notification Date, the Call Price
         shall be equal to the excess, if any, of (i) the Dollar Price
         determined as provided in Section 5 (which, in the event of termination
         after commencement of the Interim Period, shall be the Adjusted Dollar
         Price) over (ii) the aggregate principal amount of the MVPs.

                  (ii) In the case of the occurrence, prior to the Call Holder's
         election on the Notification Date to remarket the MVPs, of any event
         set forth in Section 9(b)(ii) or (v) or (viii), the Call Price shall be
         determined in the following manner: the Calculation Agent shall select
         five reference market dealers reasonably acceptable to the Company. The
         Calculation Agent shall request each reference market dealer to provide
         a quotation, as of the same time and date, of the value of the Call
         Price, determined on a commercially reasonable basis by reference,
         among other factors, to the formulation described in the preceding
         paragraph. The Call Price shall be equal to the average of the three
         quotations remaining after disregarding the highest and lowest of such
         quotations. If fewer than five quotations are obtained, the average of
         the quotations shall be used.





                                       24
<PAGE>   25

         In the case of either (i) or (ii) above, the Call Holder shall
determine the applicable Call Price on the Business Day immediately following
the date of termination or notification of the occurrence, prior to the Call
Holder's election on the Notification Date to remarket the MVPs, of any event
set forth in Section 9(b)(ii), (v) or (viii) hereof, as the case may be, or as
soon as practicable thereafter (the "Call Price Determination Date"). The Call
Holder shall promptly notify the Company of the Call Price Determination Date
and the Call Price by telephone, confirmed in writing (which may include
facsimile or other electronic transmission). The Call Price, absent manifest
error, shall be binding and conclusive upon the parties hereto.

         (f) This Agreement shall not be subject to termination by the Company.

         Section 13. Call Holder's Performance; Duty of Care. The duties and
obligations of the Call Holder shall be determined solely by the express
provisions of this Agreement and the Senior Indenture. No implied covenants or
obligations of or against the Call Holder shall be read into this Agreement or
the Senior Indenture. In the absence of bad faith on the part of the Call
Holder, the Call Holder may conclusively rely upon any document furnished to it,
which purports to conform to the requirements of this Agreement and the Senior
Indenture, as to the truth of the statements expressed in any of such documents.
The Call Holder shall be protected in acting upon any document or communication
reasonably believed by it to have been signed, presented or made by the proper
party or parties. The Call Holder or the Calculation Agent shall incur no
liability to any Beneficial Owner or Holder of MVPs in their individual capacity
or otherwise for any action or failure to act in connection with the remarketing
or otherwise. The Calculation Agent shall incur no liability to the Company
except as a result of gross negligence or willful misconduct on its part.

         Section 14. GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY AND
CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK APPLICABLE TO
CONTRACTS MADE AND TO BE PERFORMED IN SUCH STATE.

         Section 15. Term of Agreement. Unless otherwise terminated in
accordance with the provisions hereof, this Agreement shall remain in full force
and effect from the date hereof until the earlier of the first day thereafter on
which no MVPs are outstanding or the completion of the remarketing of the MVPs.
Regardless of any termination of this Agreement pursuant to any of the
provisions hereof, the obligations of the Company pursuant to Sections 10 and 12
hereof shall remain operative and in full force and effect until fully
satisfied.

         Section 16. Successors and Assigns. The rights and obligations of the
Company hereunder may not be assigned or delegated to any other person without
the prior written consent of each of the Call Holder and the Calculation Agent.
The rights and obligations of the Call Holder and the Calculation Agent
hereunder may be assigned or delegated to any affiliate thereof without the
consent of the Company, and to any other person only with the prior written
consent of the Company. This Agreement shall inure to the benefit of and be
binding upon the Company, the Call Holder and the Calculation Agent and their
respective successors and assigns, and will not confer any benefit upon any
other person, partnership, association or corporation





                                       25
<PAGE>   26

other than persons, if any, controlling the Call Holder or the Calculation Agent
within the meaning of Section 15 of the Securities Act or Section 20 of the
Exchange Act, or any indemnified party to the extent provided in Section 10
hereof, or any person entitled to contribution to the extent provided in Section
11 hereof. The terms "successors" and "assigns" shall not include any purchaser
of any MVPs merely because of such purchase.

         Section 17. Headings. Section headings have been inserted in this
Agreement as a matter of convenience of reference only, and it is agreed that
such section headings are not a part of this Agreement and will not be used in
the interpretation of any provisions of this Agreement.

         Section 18. Severability. If any provision of this Agreement shall be
held or deemed to be or shall, in fact, be invalid, inoperative or unenforceable
as applied in any particular case in any or all jurisdictions because it
conflicts with any provision of any constitution, statute, rule or public policy
or for any other reason, such circumstances shall not have the effect of
rendering the provision in question invalid, inoperative or unenforceable in any
other case, circumstance or jurisdiction, or of rendering any other provision or
provisions of this Agreement invalid, inoperative or unenforceable to any extent
whatsoever.

         Section 19. Counterparts. This Agreement may be executed in several
counterparts, each of which shall be regarded as an original and all of which
shall constitute one and the same document. 

         Section 20. Amendments. This Agreement may be amended by any instrument
in writing signed by each of the parties hereto so long as this Agreement as
amended is not inconsistent with the Senior Indenture as in effect as of the
date of any such amendment.

         Section 21. Notices. Unless otherwise specified, any notices, requests,
consents or other communications given or made hereunder or pursuant hereto
shall be made in writing (which may include facsimile or other electronic
transmission) and shall be deemed to have been validly given or made when
transmitted, delivered or mailed, registered or certified mail, return receipt

         Browning-Ferris Industries, Inc., a Delaware corporation (the
"Company"), which term includes any successor under the Senior Indenture
hereinafter referred to, for value received, hereby promises to pay to Cede &
Co., a nominee of The Depository Trust Company ("DTC"), or its registered
assigns, the principal amount of Two Hundred Million Dollars ($200,000,000), on
the Maturity Date specified above (or any earlier redemption date or repurchase
date) (each such Maturity Date, redemption date or repurchase date being
hereinafter referred to as the "Maturity Date" with respect to the principal
repayable on such date) and to pay interest thereon, at the Interest Rate per
annum specified above to January 18, 2000 (the "Remarketing Date"), and
thereafter, subject to the terms and conditions set forth herein, at the
Interest Rate determined by the Calculation Agent (as defined below) in
accordance with the procedures set forth below, until the principal hereof is
paid or duly made available for payment. The Company will pay interest in
arrears on each Interest Payment Date, if any, specified above, commencing with
the first Interest Payment Date next succeeding the Original Issue Date
specified above, and on the Maturity Date; provided, however, that if the
Original Issue Date occurs between a Record Date (as defined below) and the
related Interest Payment Date, interest payments will commence on the Interest
Payment Date immediately following the next succeeding Record Date to the holder
of this MVPs on such next succeeding Record Date. Interest on the MVPs accruing
during the period from and including the Original Issue Date to but excluding
the Remarketing Date will be payable semi-annually on January 18 and July 15 of
each year, commencing July 15, 1999. Interest on the MVPs accruing from the
Remarketing Date (if such date is not the Interim Period Remarketing Date (as
defined herein)) or the Additional Remarketing Date (as defined herein) (if the
Remarketing Date is the Interim Period Remarketing Date) will be payable
semi-annually on each day that is a six-month anniversary of such date. Interest
on the MVPs accruing during the period from and including the Remarketing Date
(if that date is the Interim Period Remarketing Date) to but excluding the
Additional Remarketing Date (the "Interim Period"), if applicable, will be
payable only on the Additional Remarketing Date. Each day on which interest is
scheduled to be paid is herein referred to as an "Interest Payment Date."
Interest on this MVPs will be computed on the basis of a 360-day year of twelve
30-day months, except that interest accruing during the Interim Period, if any,
will be computed on the basis of the actual number of days in such period over a
360-day year.

         If, pursuant to the Remarketing and Interest Calculation Agreement,
dated as of the date hereof (the "Remarketing and Interest Calculation
Agreement"), among The First Chicago National Bank, as Call Holder (the "Call
Holder"), First Chicago Capital Markets, Inc., as Calculation Agent (the
"Calculation Agent"), and the Company, the Call Holder elects to remarket the
MVPs, then, except as otherwise set forth herein, (i) this MVPs shall be subject
to mandatory tender to the Call Holder for remarketing on the Remarketing Date
and, in the event of the Interim Period, on the Additional Remarketing Date, on
the terms and subject to the conditions set forth herein, and (ii) on and after
the Remarketing Date, this MVPs shall bear interest at the rate or rates
determined by the Calculation Agent in accordance with the procedures set forth
in Section 4 herein. The Remarketing Date and the Additional Remarketing Date
shall be the remarketing dates for the MVPs. The duties of each of the
Calculation Agent and the Call Holder set forth herein shall be performed
pursuant to the Remarketing and Interest Calculation Agreement.

         Interest on this MVPs will accrue from, and including, the immediately
preceding Interest Payment Date to which interest has been paid or duly provided
for (or from, and including, the



                                        3


<PAGE>   4


Original Issue Date, if no interest has been paid or duly provided for) to, but
excluding, the applicable Interest Payment Date or the Maturity Date, as the
case may be. The interest so payable, and punctually paid or duly provided for,
on any Interest Payment Date or the Maturity Date will, subject to certain
exceptions described herein, be paid to the person in whose name this MVPs (or
one or more predecessor MVPs) is registered at the close of business on the
fifteenth calendar day (whether or not a Business Day, as defined below)
immediately preceding such Interest Payment Date or the Maturity Date except
that, in the case of the Interest Payment Date relating to the Interim Period,
interest will be payable to the persons to whom principal is payable on the
Additional Remarketing Date (each such date, a "Record Date"). Any such interest
not so punctually paid or duly provided for ("Defaulted Interest") will
forthwith cease to be payable to the Holder on any Record Date, and shall be
paid to the person in whose name this MVPs is registered at the close of
business on a special record date (the "Special Record Date") for the payment of
such Defaulted Interest to be fixed by the Trustee hereinafter referred to,
notice whereof shall be given to the Holder of this MVPs by the Trustee not less
than 10 calendar days prior to such Special Record Date or may be paid at any
time in any other lawful manner not inconsistent with the requirements of any
securities exchange on which this MVPs may be listed, and upon such notice as
may be required by such exchange, all as more fully provided for in the Senior
Indenture.

         Principal of and premium, if any, on this MVPs will be payable when due
upon presentation and surrender of this MVPs at the corporate trust office of
the Trustee maintained for that purpose in the City of Dallas, Texas currently
located at 1201 Main Street, 18th Floor, Dallas, Texas 75202, or at such other
paying agency in the Borough of Manhattan, The City of New York, as the Company
may determine. Payment of interest due on any Interest Payment Date or the
Maturity Date will be made by check mailed to the address of the person entitled
thereto as such address shall appear in the Security Register maintained at the
aforementioned office of the Trustee; provided, however, that a holder of U.S.
$10,000,000 or more in aggregate principal amount of MVPs will be entitled to
receive interest payments on such Interest Payment Date or the Maturity Date by
wire transfer of immediately available funds if appropriate wire transfer
instructions have been received in writing by the Trustee not less than 15
calendar days prior to such Interest Payment Date or the Maturity Date. Any such
wire transfer instructions received by the Trustee shall remain in effect until
revoked by such holder. Notwithstanding the foregoing or any provision hereof,
if this MVPs is a Global Security (as evidenced by the legend first set forth
above and provided in the Senior Indenture), and is held in book-entry form
through the facilities of DTC, payments on this MVPs will be made to DTC or its
nominee in accordance with the arrangements then in effect between the Trustee
and DTC.

         If any Interest Payment Date or the Maturity Date falls on a day that
is not a Business Day, the required payment of principal, premium, if any,
and/or interest, shall be made on the next succeeding Business Day with the same
force and effect as if it were made on the date such payment was due, and no
interest shall accrue on the amount so payable for the period from and after
such Interest Payment Date or the Maturity Date, as the case may be, to the date
of payment on the next succeeding Business Day.

         As used herein, "Business Day" means any day other than a Saturday, a
Sunday or a day on which banking institutions in The City of New York, Houston,
Texas or Chicago, Illinois are authorized or obligated by law, regulation or
executive order to close and, in the case of the



                                       4

determination of the Reference Rate (as defined below) that is based upon
deposits in U.S. dollars in London, the City of London.

         The Company is obligated to make payment of principal, premium, if any,
and interest in respect of this MVPs in United States dollars.

         Reference is hereby made to the further provisions of this MVPs set
forth following the Trustee's Certificate of Authentication (the "Certificate of
Authentication") set forth below.

         Unless the Certificate of Authentication hereon has been executed by
the Trustee by manual signature, this MVPs shall not be entitled to any benefit
under the Senior Indenture or be valid or obligatory for any purpose.

                        BROWNING-FERRIS INDUSTRIES, INC.
                 6.08% Market Value Put securities(SM) ("MVPs"SM)

         1. Senior Indenture. (a) This MVPs is one of a duly authorized series
of Securities of the Company issued under a Restated Indenture, dated as of
September 1, 1991 (as amended, modified or supplemented from time to time, the
"Senior Indenture"), between the Company and Chase Bank of Texas, National
Association (formerly known as Texas Commerce Bank National Association as
successor trustee to First City, Texas-Houston, National Association, which was
formerly First City National Bank of Houston) (the "Trustee," which term
includes any successor trustee under the Senior Indenture), to which Senior
Indenture and all indentures supplemental thereto reference is hereby made for a
statement of the respective rights, limitations of rights, duties and immunities
thereunder of the Company, the Trustee and the Holders of the MVPs, and of the
terms upon which the MVPs are authenticated and delivered. The MVPs are limited
to $250,000,000 aggregate principal amount and are designated "6.08% Market
Value Put securities" ("MVPs") subject to the provisions of the Senior
Indenture. All terms used but not defined in this MVPs shall have the meanings
assigned to such terms in the Senior Indenture. Except where the context
otherwise requires, all references in this MVPs to "this MVPs," "this Security,"
"herein" or "hereof" or similar terms shall include the Senior Indenture.

         (b) This MVPs is issuable only in registered form without coupons in
minimum denominations of U.S. $1,000 and integral multiples thereof.

         (c) This MVPs will not be subject to any sinking fund.

         2. Mandatory Tender. Provided that on a Business Day not later than
five Business Days prior to the Remarketing Date the Call Holder notifies the
Company and the Trustee of its election to purchase the MVPs on the Remarketing
Date for remarketing (the "Notification Date"), the MVPs shall be subject to
mandatory tender to the Call Holder, and the Call Holder shall be obligated to
purchase the MVPs, for remarketing on the Remarketing Date and, if such date is
designated as the Interim Period Remarketing Date, the Additional Remarketing
Date thereafter, subject in each case to the conditions described herein and set
forth in the Remarketing and Interest Calculation Agreement. The purchase price
for the tendered MVPs shall equal 100% of the principal amount thereof. From and
including the Remarketing Date (if such date is not the Interim Period
Remarketing Date) or the Additional Remarketing Date (if the Remarketing Date is
the Interim Period Remarketing Date), the MVPs will bear interest at the
Interest Rate to Maturity, determined pursuant to Section 4 hereof. During the
Interim Period, if any, the MVPs will bear interest at the Interim Period
Interest Rate determined pursuant to Section 4 hereof. If the Call Holder elects
to remarket the MVPs, the obligation of the Call Holder to purchase the MVPs on
any remarketing date is subject to the conditions specified in Section 9 of the
Remarketing and Interest Calculation Agreement. If the Call Holder purchases
MVPs on any remarketing date, it must purchase all of the MVPs. If for any
reason the Call Holder does not purchase all of the MVPs on any remarketing
date, the Company shall be required to repurchase from the Beneficial Owners
thereof, and the Beneficial Owners will be required to sell to the Company, all
the MVPs at a price equal to the principal amount thereof plus all accrued and
unpaid interest, if any, on the MVPs to such remarketing date as provided in
Section 6 hereof.

         "Beneficial Owner" shall mean each person who acquires an interest in
the MVPs which is reflected on the records of the DTC through its participants.

         3. Remarketing Dates; Adjustment of Maturity Date. If the Call Holder
gives notice of its intention to purchase the MVPs on January 18, 2000, then not
later than 4:00 p.m., New York City time, on the fourth Business Day prior to
January 18, 2000, the Company, after consultation with the Call Holder, may
notify the Call Holder, the Trustee and DTC by telephone, confirmed in writing
that it elects January 18, 2000 to be the Interim Period Remarketing Date (the
"Interim Period Remarketing Date"). The Company will be eligible to make such
notification if at such time its senior unsecured debt is rated at least "Baa3"
by Moody's Investors Service, Inc. and "BBB-" by Standard & Poor's Ratings
Services (or the equivalent thereof by each such rating agency) at the time of
such notification or if the Call Holder waives this requirement in its sole
discretion. If the Company does not provide such notification, January 18, 2000
will be the only remarketing date and the Maturity Date will be January 18,
2002. If the Company provides such notification, then (i) the Additional
Remarketing Date will be one of the 26 following one-week anniversary dates of
January 18, 2000 (or if any such day is not a Business Day, the next succeeding
Business Day) designated by the Company not later than the fifth Business Day
prior to such one-week anniversary date (the "Additional Remarketing Date")
except that, if the Company fails to so designate the Additional Remarketing
Date, the Additional Remarketing Date will be the date that is the 26th week
anniversary of January 18, 2000 (or if such day is not a Business Day, the next
following Business Day) and (ii) the Maturity Date of the MVPs will be the date
that is the two-year anniversary of the Additional Remarketing Date (whether or
not a Business Day).

         4. Determination of Applicable Interest Rate. From and including the
Remarketing Date (if such date is not the Interim Period Remarketing Date) or
the Additional Remarketing Date (if the Remarketing Date is designated the
Interim Period Remarketing Date) to but excluding the Maturity Date, the MVPs
will bear interest at the Interest Rate to Maturity. During the Interim Period,
if any, the MVPs will bear interest at the Interim Period Interest Rate.

                  (a) Interest Rate to Maturity. Subject to the Call Holder's
         election to remarket the MVPs as provided in Section 2 hereof and
         subject further to Sections 4(c) and 7 hereof and the Remarketing and
         Interest Calculation Agreement, the Interest Rate to Maturity shall be
         determined by the Calculation Agent by 3:30 p.m., New York City time,
         on the third Business Day preceding the Remarketing Date (if such date
         is not the Interim Period Remarketing Date) or the Additional
         Remarketing Date (in the event of the Interim Period) (subject to
         Section 4(c) hereof, the "Determination Date") to the nearest one
         hundred-thousandth (0.00001) of one percent per annum by soliciting
         firm committed bids, expressed as a spread over the Base Rate, to
         purchase all outstanding MVPs at the Dollar Price, and by selecting the
         lowest such firm committed bid (regardless of whether each of the
         Reference Corporate Dealers actually submits bids). The Interest Rate
         to Maturity will be equal to the sum of 4.68% (the "Base Rate") plus
         the Applicable Spread. The Interest Rate to Maturity announced by the
         Calculation Agent, absent manifest error, shall be binding and
         conclusive upon the Beneficial Owners and Holders of the MVPs, the Call
         Holder, the Company and the Trustee.

                  "Applicable Spread" shall mean the lowest bid expressed as a
         spread (in the form of a percentage or in basis points) above the Base
         Rate, obtained by the Calculation



                                       8

         Reference Corporate Dealers for the full aggregate principal amount of
         the MVPs at the Dollar Price, but assuming (i) an issue date equal to
         the Remarketing Date (if such date is not the Interim Period
         Remarketing Date) or the Additional Remarketing Date (in the event of
         an Interim Period), with settlement on such date without accrued
         interest, (ii) a maturity date equal to the Maturity Date of the MVPs,
         and (iii) a stated annual interest rate, payable semi-annually, equal
         to the Base Rate plus the spread bid by the applicable Reference
         Corporate Dealer.

                  "Dollar Price" shall mean, with respect to the MVPs, the
         present value, as of the Remarketing Date, of the Remaining Scheduled
         Payments discounted to the Remarketing Date, on a semi-annual basis
         (assuming a 360-day year consisting of twelve 30-day months), at the
         Treasury Rate, except that in the case of the Additional Remarketing
         Date, the Dollar Price will be the Adjusted Dollar Price.

                  "Adjusted Dollar Price" shall mean, with respect to the
         Additional Remarketing Date, the Dollar Price as of the Remarketing
         Date (determined by the Calculation Agent on the third Business Day
         prior to the Remarketing Date) plus the product of (i) such Dollar
         Price less the aggregate principal amount of the MVPs outstanding as of
         the Remarketing Date, (ii) the weighted average per annum Interim
         Period Interest Rate for the Interim Period, and (iii) the number of
         days in the Interim Period divided by 360.

                  "Reference Corporate Dealers" shall mean each of First Chicago
         Capital Markets, Inc., its successors and four other leading dealers of
         publicly traded debt securities of the Company selected by the Call
         Holder.

                  "Treasury Rate" shall mean the rate per annum equal to the
         semi-annual equivalent yield to maturity or interpolated (on a 30/360
         day count basis) yield to maturity of the Comparable Treasury Issue for
         value on the Remarketing Date, assuming a price for the Comparable
         Treasury Issue (expressed as a percentage of its principal amount),
         equal to the Comparable Treasury Price.

                  "Comparable Treasury Issue" shall mean the United States
         Treasury security selected by the Calculation Agent as having an actual
         or interpolated maturity comparable to the remaining term of the MVPs.

                  "Comparable Treasury Price" shall mean, (a) the offer price
         for the Comparable Treasury Issue (expressed as a percentage of its
         principal amount) on the third Business Day prior to the Remarketing
         Date, as set forth on Telerate Page 500 (as defined below), adjusted to
         reflect settlement on the Remarketing Date if prices quoted on Telerate
         Page 500 are for settlement on any date other than the Remarketing
         Date, or (b) if such page (or any successor page) is not displayed or
         does not contain such offer price on such Business Day, (i) the average
         of five Reference Treasury Dealer Quotations (as defined below) for

         highest or lowest quotation, in which case only one such highest and/or
         lowest quotation shall be excluded), or (ii) if the Calculation Agent
         obtains fewer than four such Reference Treasury Dealer Quotations, the
         average of all such Reference Treasury Dealer Quotations.

                  "Telerate Page 500" means the display designated as "Telerate
         Page 500" on Bridge Telerate, Inc. (or such other page as may replace
         Telerate Page 500 on such service) or such other service displaying the
         offer prices specified in (a) above as may replace Bridge Telerate,
         Inc. The Calculation Agent shall have the discretion to select the time
         at which the Comparable Treasury Price is determined on the third

                  "Reference Treasury Dealer Quotations" shall mean, with
         respect to each Reference Treasury Dealer, the offer price for the
         Comparable Treasury Issue (expressed in each case as a percentage of

         writing to the Calculation Agent by such Reference Treasury Dealer by
         3:30 p.m., on the third Business Day immediately preceding the
         Remarketing Date.

                  "Reference Treasury Dealer" shall mean each of First Chicago
         Capital Markets, Inc., Chase Securities Inc., NationsBanc Montgomery
         Securities LLC, Goldman, Sachs & Co. and Morgan Stanley & Co.
         Incorporated and their respective successors; provided, however, that
         if any of the foregoing or their affiliates shall cease to be a primary
         U.S. Government securities dealer (a "Primary Treasury Dealer"), the
         Calculation Agent shall substitute therefor another Primary Treasury
         Dealer.

                  "Remaining Scheduled Payments" shall mean, with respect to the
         MVPs, the remaining scheduled payments of the principal thereof and
         interest thereon, calculated at the Base Rate only and assuming (i) a

         not elect the Remarketing Date to be the Interim Period Remarketing
         Date.

                  (b) Determination of Interim Period Interest Rate. The
         interest rate for the Interim Period, if any, will be reset on each
         Interest Reset Date during the Interim Period and will be equal to the
         Reference Rate in respect of the applicable Interest Reset Date plus
         the Basic Spread, in each case as calculated by the Calculation Agent
         (the "Interim Period Interest Rate"). The Wednesday of each week during
         the Interim Period will be an "Interest Reset Date." The "Interest
         Determination Date" applicable to an Interest Reset Date will be the
         second Business Day preceding such Interest Reset Date. The interest
         rate in effect from and including the Interim Period Remarketing Date
         (which is the first day of the Interim Period) to but excluding the
         first Interest Reset Date during such Interim Period will be determined
         as if the Interim Period Remarketing Date were an Interest Reset Date
         and the Interest Determination Date for such Interest Reset Date were
         the second Business Day prior to the Interim Period Remarketing Date.

                  The "Reference Rate" shall mean, with respect to the Interim
         Period, one of the following reference rates selected by the Company
         and notified to the Calculation Agent no later than four Business Days
         prior to the Interim Period Remarketing Date: (i) the per annum rate
         for deposits in U.S. dollars for a period of one week shown on Telerate
         page 3750 (or any successor page) at 11:00 a.m., London time, on the
         applicable Interest Determination Date, (ii) the per annum rate equal
         to the average of the federal funds rates shown on Telerate page 5 (or
         any successor page) as of 11:00 a.m., New York City time, on the
         applicable Interest Determination Date and each of the four Business
         Days prior to such Interest Determination Date, or (iii) the one-week
         "AA" non-financial commercial



                                       10
<PAGE>   11


         paper rate shown on the Internet world wide web page of the Board of
         Governors of the Federal Reserve System at
         www.bog.frb.fed.us/releases/CP/ (or any successor page) as of 11:00
         a.m., New York City time, on the applicable Interest Determination
         Date. If the reference rate on the applicable designated page (or
         successor page) is not published on the specified page by the specified
         time on the applicable date or dates, then the reference rate
         determined as of the applicable Interest Determination Date will be the
         reference rate in effect on such Interest Determination Date.

                  The "Basic Spread" will be the lowest firm commitment bid
         expressed as a spread (in the form of a percentage or a number of basis
         points (plus or minus)) with respect to the Reference Rate, obtained by
         the Calculation Agent on the third Business Day prior to the Interim
         Period Remarketing Date from the bids quoted from up to five Reference
         Money Market Dealers on such date for the full aggregate principal
         amount of the MVPs at a dollar price equal to par, but assuming (i)
         that the purchase date is the Interim Period Remarketing Date, with
         settlement on such date without accrued interest, (ii) that the
         maturity date is the day that is 26 weeks from the Interim Period
         Remarketing Date, (iii) that the MVPs are callable by the Call Holder
         on a weekly basis after the Interim Period Remarketing Date, (iv) that
         the MVPs will be repurchased by the Company at par on the day that is
         26 weeks from the Interim Period Remarketing Date if not previously
         called by the Call Holder, and (v) a stated annual interest rate,
         payable on the Additional Remarketing Date, equal to the Reference Rate
         plus the spread bid by the applicable Reference Money Market Dealer.

                  "Reference Money Market Dealers" means each of First Chicago
         Capital Markets, Inc., Chase Securities Inc., NationsBanc Montgomery
         Securities LLC, Goldman, Sachs & Co. and Morgan Stanley & Co.
         Incorporated and their respective successors; provided, however, that
         if any of the foregoing or their affiliates shall cease to be a leading
         dealer of publicly traded debt securities of the Company and a leading
         dealer in money market instruments (a "Primary Money Market Dealer"),
         the Calculation Agent shall substitute therefor another Primary Money
         Market Dealer.

                  The Interim Period Interest Rate and the amount of interest
         payable on the Additional Remarketing Date shall each be determined by
         the Calculation Agent and, absent manifest error, shall be binding and
         conclusive upon the Beneficial Owners and Holders of the MVPs, the Call
         Holder, the Company and the Trustee.

                  (c) Redetermination of Interest Rate to Maturity.
         Notwithstanding any provision herein to the contrary, upon the
         occurrence, at any time after determination of the Interest Rate to
         Maturity on the Determination Date and prior to 3:30 p.m., New York
         City time, on the Business Day immediately preceding the Remarketing
         Date, of any event as specified in Section 12(b) of the Remarketing and
         Interest Calculation Agreement, the Call Holder, in its sole discretion
         at any time between the Determination Date and 3:30 p.m., New York City
         time, on the Business Day immediately preceding the Remarketing Date
         (if such date is not the Interim Period Remarketing Date) or the
         Additional Remarketing Date (in the event of the Interim Period), may
         elect to purchase the MVPs for remarketing and determine a new Interest
         Rate to Maturity in the manner provided in Section 4(a) hereof, except
         that for purposes of determining the new Interest Rate to Maturity
         pursuant to this paragraph, the Determination Date referred to therein
         shall be



                                       11
<PAGE>   12


         the date of such election and redetermination. The Calculation Agent
         shall notify the Company, the Trustee and DTC by telephone, confirmed
         in writing (which may include facsimile or other electronic
         transmission), by 4:00 p.m., New York City time, on the date of such
         election, of the new Interest Rate to Maturity applicable to the MVPs.
         Thereupon, such new Interest Rate to Maturity shall supersede and
         replace any Interest Rate to Maturity previously determined by the
         Calculation Agent and, absent manifest error, shall be binding and
         conclusive upon the Beneficial Owners and Holders of the MVPs on or
         after the Remarketing Date, the Company and the Trustee.

         5. Notification of Results; Settlement. Provided the Call Holder has
previously notified the Company and the Trustee on the Notification Date of its
intention to purchase all MVPs on January 18, 2000 and subject to Section 7
below, the Calculation Agent will notify the Company, the Trustee and DTC by
telephone, confirmed in writing (which may include facsimile or other electronic
transmission), by 4:00 p.m., New York City time, on the Determination Date, of
the Interest Rate to Maturity. If January 18, 2000 is the Interim Period
Remarketing Date, the Calculation Agent will provide the Company, the Trustee
and DTC notice in accordance with the preceding sentence, on the second Business
Day prior to January 18, 2000, of the Interim Period Interest Rate which will
initially be in effect. All of the outstanding MVPs shall be automatically
delivered to the account of the Trustee, by book-entry through DTC pending
payment of the purchase price therefor, on the applicable remarketing date.

         In the event that the Call Holder purchases the tendered MVPs on any
remarketing date, the Call Holder shall make or cause the Trustee to make
payment to the DTC Participant of each Beneficial Owner of MVPs, by book-entry
through DTC no later than the close of business on the applicable remarketing
date against delivery through DTC of such Beneficial Owner's tendered MVPs, of
100% of the principal amount of the tendered MVPs that have been purchased for
remarketing by the Call Holder. If the Call Holder does not purchase all of the
MVPs on any remarketing date, it shall be the obligation of the Company to make
or cause to be made such payment for the MVPs, as provided in Section 6 hereof.
In any case, the Company shall make or cause the Trustee to make payment of
interest to each Beneficial Owner of MVPs due on any remarketing date by
book-entry through DTC no later than the close of business on such remarketing
date.

         "DTC Participant" shall mean any person that has an account with DTC
through which Beneficial Owners acquire, directly or indirectly, an interest in
the MVPs.

         The transactions set forth herein shall be executed through DTC in
accordance with the procedures of DTC, and the accounts of the respective DTC
Participants will be debited and credited and the MVPs delivered by book-entry
as necessary to effect the purchases and sales thereof.

         The tender and settlement procedures set forth herein, including
provisions for payment by purchasers of MVPs in the remarketing or for payment
to selling Beneficial Owners of MVPs, may be modified, without the consent of
the Beneficial Owners and Holders of the MVPs, to the extent required by DTC or
to the extent required to facilitate the tender and remarketing of MVPs in
certificated form, if the book-entry system is no longer available for the MVPs
at the time of the remarketing. In addition, the Call Holder may, without the
consent of Holders or



                                       12
<PAGE>   13




Beneficial Owners of the MVPs, modify the tender and settlement procedures set
forth above in order to facilitate the tender and settlement process.

         As long as DTC's nominee holds the certificates representing any MVPs
in the book-entry system of DTC, no certificates for such MVPs will be delivered
by any selling Beneficial Owner to reflect any transfer of such MVPs effected in
the remarketing.

         6. Repurchase. In the event that (i) the Calculation Agent for any
reason (other than redemption by the Company of the MVPs from the Call Holder
pursuant to Section 7 hereof) does not notify the Company of (A) the Interest
Rate to Maturity by 4:00 p.m., New York City time, on the Determination Date or
(B) in the event of the Interim Period, the Interim Period Interest Rate which
will initially be in effect, by 4:00 p.m. New York City time on the second
Business Day prior to January 18, 2000, or (ii) prior to any remarketing date,
the Call Holder has resigned and no successor has been appointed on or before
(A) the Determination Date or (B) in the event of the Interim Period, the second
Business Day prior to January 18, 2000, or (iii) at any time after the Call
Holder elects on the Notification Date to remarket the MVPs, any event as set
forth in Section 9 or Section 12 of the Remarketing and Interest Calculation
Agreement shall have occurred, or (iv) the Call Holder for any reason does not
elect to purchase the MVPs for remarketing on any remarketing date, (v) the Call
Holder for any reason does not purchase all tendered MVPs on the Remarketing
Date, or (vi) a Reference Corporate Dealer shall fail to purchase all of the
MVPs from the Call Holder on the Remarketing Date (if such date is not the
Interim Period Remarketing Date) or Additional Remarketing Date (in the event of
the Interim Period), or (vii) in the event of the Interim Period, a Reference
Money Market Dealer shall fail to purchase all of the MVPs on the Interim Period
Remarketing Date, then the Company shall repurchase all the MVPs as a whole on
the remarketing date relating to such event (which, in the case of clause (iii)
that occurs during the Interim Period shall be the Additional Remarketing Date)
at a price equal to 100% of the principal amount of the MVPs plus all accrued
and unpaid interest, if any, on the MVPs to such remarketing date. In any such
case, payment will be made by the Company through the Trustee to the DTC
Participant of each tendering Beneficial Owner of MVPs, by book-entry through
DTC no later than the close of business on the applicable remarketing date
against delivery through DTC of such Beneficial Owner's tendered MVPs.

         7. Redemption. If the Call Holder elects to remarket the MVPs in
accordance with the terms of the Remarketing and Interest Calculation Agreement,
then not later than four Business Days immediately preceding the Remarketing
Date or the Additional Remarketing Date, if any, the Company may irrevocably
elect to exercise its right to redeem the outstanding MVPs, in whole but not in
part, from the Call Holder on the remarketing date immediately following such
election at the Optional Redemption Price.

         The "Optional Redemption Price" shall be the sum of (i) the greater of
(a) 100% of the principal amount of the MVPs and (b) the Dollar Price (which if
such remarketing date is the Additional Remarketing Date, will equal the
Adjusted Dollar Price), plus (ii) in the case of either (a) or (b), accrued and
unpaid interest on the principal amount being redeemed to the date of payment in
respect of such redemption.

         Provided that the MVPs have not been repurchased pursuant to Section 6
hereof or redeemed pursuant to the two immediately preceding paragraphs,
following the remarketing of the MVPs on the Remarketing Date (if such date is
not the Interim Period Remarketing Date) or



                                       13
<PAGE>   14



the Additional Remarketing Date (in the event of the Interim Period), the MVPs
will be redeemable, in whole or from time to time in part, at the option of the
Company after the Remarketing Date (if such date is not the Interim Period
Remarketing Date) or the Additional Remarketing Date (in the event of the
Interim Period) at a redemption price equal to the greater of (i) 100% of the
principal amount of the MVPs to be redeemed and (ii) an amount (determined by
the Quotation Agent (as defined below)) equal to the sum of the present values
of the remaining scheduled payments of principal and interest on the MVPs to be
redeemed (not including any portion of such payments of interest accrued as of
the date of redemption) discounted to the date of redemption on a semi-annual
basis (assuming a 360-day year consisting of twelve 30-day months) at the
Adjusted Treasury Rate (as defined below) plus 15 basis points, plus, in either
case, accrued interest thereon to the date of redemption.

         "Adjusted Treasury Rate" means, with respect to any redemption date,
the rate per annum equal to the semi-annual equivalent yield to maturity of the
Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue
(expressed as a percentage of its principal amount) equal to the Comparable
Treasury Price for such redemption date.

         "Comparable Treasury Issue" means the United States Treasury security
selected by the Quotation Agent as having a maturity comparable to the remaining
term of the MVPs to be redeemed that would be utilized, at the time of selection
and in accordance with customary financial practice, in pricing new issues of
corporate debt securities of comparable maturity to the remaining term of such
MVPs.

         "Comparable Treasury Price" means, with respect to any redemption date,
(i) the average of the Reference Treasury Dealer Quotations for such redemption
date, after excluding the highest and lowest such Reference Treasury Dealer
Quotations, or (ii) if the Trustee obtains fewer than three such Reference
Treasury Dealer Quotations, the average of such Quotations, such average in any
case to be determined by the Quotation Agent, or (iii) if only one Reference
Treasury Dealer Quotation is received, such Quotation.

         "Quotation Agent" means the Reference Treasury Dealer appointed by the
Company.

         "Reference Treasury Dealer" means (i) each of First Chicago Capital
Markets, Inc., Chase Securities Inc., NationsBanc Montgomery Securities LLC,
Goldman, Sachs & Co. and Morgan Stanley & Co. Incorporated and their respective
successors; provided, however, that if any of the foregoing shall cease to be a
primary U.S. Government securities dealer (a "Primary Treasury Dealer"), the
Company shall substitute therefor another Primary Treasury Dealer, and (ii) any
other Primary Treasury Dealer(s) selected by the Company.

         "Reference Treasury Dealer Quotations" means, with respect to each
Reference Treasury Dealer and any redemption date, the average, as determined by
the Quotation Agent, of the bid and asked prices for the Comparable Treasury
Issue (expressed in each case as a percentage of its principal amount) quoted in
writing to the Trustee by such Reference Treasury Dealer at 5:00 p.m., New York
City time, on the third Business Day preceding such redemption date.

         Notice of any redemption will be mailed at least 30 days but not more
than 60 days before the redemption date to each holder of the MVPs to be
redeemed. Unless the Company defaults in payment of the redemption price, on and
after the redemption date, interest will cease



                                       14
<PAGE>   15



to accrue on the MVPs or portions thereof called for redemption. If less than
all of the MVPs are to be redeemed, the MVPs (or portions thereof) to be
redeemed shall be selected by the Trustee by such method as the Trustee shall
deem fair and appropriate.

         8. Effect of Events of Default. If an Event of Default, as defined in
the Senior Indenture, shall occur and be continuing, the principal of the MVPs
may be declared due and payable in the manner and with the effect provided in
the Senior Indenture.

         9. Defeasance. Notwithstanding any provision to the contrary in the
Senior Indenture or otherwise, prior to the Remarketing Date, neither the
Company nor any of its subsidiaries or affiliates shall defease, purchase or
otherwise acquire, or enter into any agreement to defease, purchase or otherwise
acquire, any of the MVPs prior to the remarketing thereof by the Call Holder.

         10. Maintenance in Book-Entry Form. Notwithstanding any provision to
the contrary set forth in the Senior Indenture, the Company (i) shall use its
best efforts to maintain the MVPs in book-entry form with DTC or any successor
thereto and to appoint a successor depositary to the extent necessary to
maintain the MVPs in book-entry form, and (ii) waives any discretionary right it
otherwise has under the Senior Indenture to cause the MVPs to be issued in
certificated form.

         11. Amendment and Modification. The Senior Indenture permits, with
certain exceptions as therein provided, the amendment thereof and the
modification of the rights and obligations of the Company and the rights of the
Holders of the Securities at any time by the Company and the Trustee with the
consent of the Holders of not less than a majority of the aggregate principal
amount of all Securities at the time outstanding of each series affected
thereby. The Senior Indenture also contains provisions permitting the Holders of
not less than a majority of the aggregate principal amount of the outstanding
Securities of any series, on behalf of the Holders of all such Securities, to
waive compliance by the Company with certain provisions of the Senior Indenture.
Furthermore, provisions in the Senior Indenture permit the Holders of not less
than a majority of the aggregate principal amount of the outstanding Securities
of any series, in certain instances, to waive, on behalf of all of the Holders
of Securities of such series, certain past defaults under the Senior Indenture
and their consequences. Any such consent or waiver by the Holder of this MVPs
shall be conclusive and binding upon such Holder and upon all future Holders of
this MVPs and other MVPs issued upon the registration or transfer hereof or in
exchange herefor or in lieu hereof, whether or not notation or such consent or
waiver is made upon this MVPs. Without the consent of any Holder, (i) the
Company and the Trustee may amend or supplement the Senior Indenture or the MVPs
to cure any ambiguity, defect or inconsistency or to make certain other
specified changes or any change that does not materially adversely affect the
rights of any Holder and (ii) the tender and settlement procedures may be
modified as provided in Section 3(b) above. Holders of MVPs may not enforce
their rights pursuant to the Senior Indenture or the MVPs except as permitted in
the Senior Indenture.

         12. Obligation to Pay Principal, Premium, if any, and Interest. No
reference herein to the Senior Indenture and no provision of this MVPs or of the
Senior Indenture shall alter or impair the obligation of the Company, which is
absolute and unconditional, to pay principal, premium, if any, and interest in
respect of this MVPs at the times, places and rate or formula, and in the manner
and coin or currency, herein prescribed.



                                       15

         13. Transfer and Exchange. As provided in the Senior Indenture and
subject to certain limitations therein and herein set forth (including without
limitation the restrictions on transfer under the Senior Indenture in the event
this MVPs is a Global Security as evidenced by the legend first set forth above
and provided in the Senior Indenture), the transfer of this MVPs is registrable
in the Security Register of the Company upon surrender of this MVPs for
registration of transfer at the office or agency of the Security Registrar in
Dallas, Texas designated for such purpose, duly endorsed by, or accompanied by a
written instrument of transfer in form satisfactory to the Company and the
Security Registrar duly executed by, the Holder hereof or by his attorney duly
authorized in writing, and thereupon one or more new MVPs, of authorized
denominations and for the same aggregate principal amount and otherwise bearing
identical terms and provisions, will be issued to the designated transferee or
transferees.

         As provided in the Senior Indenture and subject to certain limitations
therein and herein set forth (including without limitation the restrictions on
transfer under the Senior Indenture in the event this MVPs is a global Security
as evidenced by the legend first set forth above and provided in the Senior
Indenture), this MVPs is exchangeable for a like aggregate principal amount of
MVPs of different authorized denominations but otherwise having the same terms
and conditions, as requested by the Holder hereof surrendering the same at the
office or agency of the Security Registrar in Dallas, Texas designated for such
purpose.

         No service charge shall be made for any such registration of transfer
or exchange of MVPs, but the Company or the Security Registrar may require
payment of a sum sufficient to cover any tax or other governmental charge that
may be imposed in relation thereto. Initially, the Trustee will act as Security
Registrar and the office at which this MVPs must be surrendered for registration
of transfer or exchange is currently the corporate trust department of the
Trustee, 1201 Main Street, 18th Floor, Dallas, Texas 75202.

         Prior to due presentment of this MVPs for registration of transfer, the
Company, the Trustee and any agent of the Company or the Trustee may treat the
person in whose name this MVPs is registered as the owner thereof for all
purposes, whether or not this MVPs be overdue, and neither the Company, the
Trustee nor any such agent shall be affected by notice to the contrary.

         14. Treatment for United States Federal Income Tax Purposes. Each
Holder of this MVPs, by virtue of its purchase hereof, agrees, with respect to
the period from the Original Issue Date to the Remarketing Date, to treat this
MVPs as a fixed rate debt instrument that matures on the Remarketing Date for
United States Federal income tax purposes.

         15. Governing Law. The Senior Indenture and this MVPs shall be governed
by and construed in accordance with the laws of the State of Texas.
