(i.e., King County).

        The Company is a fully-integrated real estate organization with in-house

the Company believes it is well-positioned to continue to take advantage of
opportunities to develop and acquire upscale apartment homes in its target
markets.

        The Company elected to be taxed as a REIT for federal income tax
purposes for the year ended December 31, 1994 and has not revoked such election.
The Company was incorporated under the laws of the State of California in 1978
and reincorporated under the laws of the State of Maryland, pursuant to a
reincorporation merger, in July 1995. Its executive offices are located at 4340

                  RATIOS OF EARNINGS TO COMBINED FIXED CHARGES
                          AND PREFERRED STOCK DIVIDENDS

        The following table sets forth the Company's consolidated ratios of
earnings to combined fixed charges and preferred stock dividends for the periods
shown:

</TABLE>

- ------------------------------

(1)     Ratios for the period January 1 - March 16, 1994 and the years ended
        1993 and 1992 reflect periods prior to the recapitalization and initial
        public offering of the Company on March 17, 1994. The earnings for these
        periods were inadequate to cover fixed charges as follows:

               Period January 1 - March 16, 1994                   $    716,000
               Year ended December 31, 1993                             447,000
               Year ended December 31, 1992                           3,916,000

The ratios of earnings to fixed charges were computed by dividing earnings by
fixed charges. For this purpose, earnings consist of pre-tax income from
continuing operations plus fixed charges. Fixed charges consist of interest
expense, capitalized interest and the amortization of debt issuance costs. The
Company issued 2,308,800 shares of Series A Preferred Stock, par value $.01 per
share (the "Series A Preferred Stock"), in October 1995, 405,022 shares of
Series B Preferred Stock, par value $.01 per share (the "Series B Preferred
Stock"), in May 1996 and 2,300,000 shares of Series C Preferred Stock in June
1997.


                         DESCRIPTION OF DEBT SECURITIES

GENERAL

        The Debt Securities will be direct unsecured obligations of the Company
and may be either senior Debt Securities ("Senior Securities") or subordinated
Debt Securities ("Subordinated Securities"). The Debt Securities will be issued
under one or more indentures, each dated as of a date prior to the issuance of
the Debt Securities to which it relates. Senior Securities and Subordinated
Securities may be issued pursuant to separate indentures (respectively, a
"Senior Indenture" and a "Subordinated Indenture"), in each case between the
Company and a trustee (a "Trustee"), which may be the same Trustee, and in the
form that has been filed as an exhibit to the Registration Statement of which
this Prospectus is a part, subject to such amendments or supplements as may be
adopted from time to time. The Senior Indenture and the Subordinated Indenture,
as amended or supplemented from time to time, are sometimes hereinafter referred
to collectively as the "Indentures." The Indentures will be subject to and
governed by the Trust Indenture Act of 1939, as amended (the "TIA"). The
statements made under this heading relating to the Debt Securities and the
Indentures are summaries of the anticipated provisions thereof, do not purport
to be complete and are qualified in their entirety by reference to the
Indentures and such Debt Securities.

        Capitalized terms used herein and not defined shall have the meanings
assigned to them in the applicable Indenture.


                                        4
<PAGE>   6
TERMS

        Unless otherwise indicated in the applicable Prospectus Supplement, the
indebtedness represented by the Senior Securities will rank equally with all
other unsecured and unsubordinated indebtedness of the Company. The indebtedness
represented by Subordinated Securities will be subordinated in right of payment
to the prior payment in full of the Senior Debt of the Company as described
under "--Subordination." The particular terms of the Debt Securities offered by
a Prospectus Supplement will be described in the applicable Prospectus
Supplement, along with any applicable modifications of or additions to the
general terms of the Debt Securities as described herein and in the applicable
Indenture and any applicable federal income tax considerations. Accordingly, for
a description of the terms of any series of Debt Securities, reference must be
made to both the Prospectus Supplement relating thereto and the description of
the Debt Securities set forth in this Prospectus.

        Except as set forth in any Prospectus Supplement, the Debt Securities
may be issued without limit as to aggregate principal amount, in one or more
series, in each case as established from time to time by the Company or as set
forth in the applicable Indenture or in one or more indentures supplemental to
such Indenture. All Debt Securities of one series need not be issued at the same
time and, unless otherwise provided, a series may be reopened, without the
consent of the holders of such series, for issuance of additional Debt
Securities of such series.

        Each Indenture will provide that the Company may, but need not,
designate more than one Trustee thereunder, each with respect to one or more
series of Debt Securities. Any Trustee under an Indenture may resign or be
removed with respect to one or more series of Debt Securities and a successor
Trustee may be appointed to act with respect to such series. In the event that
two or more persons are acting as Trustee with respect to different series of
Debt Securities, each such Trustee shall be a Trustee of a trust under the
applicable Indenture separate and apart from the trust administered by any other
Trustee, and, except as otherwise indicated herein, any action described herein
to be taken by each Trustee may be taken by each such Trustee with respect to,
and only with respect to, the one or more series of Debt Securities for which it
is Trustee under the applicable Indenture.

        The following summaries set forth certain general terms and provisions
of the Indentures and the Debt Securities. The Prospectus Supplement relating to
the series of Debt Securities being offered will contain further terms of such
Debt Securities, including the following specific terms:

                      bearer form and, if in registered form, the denominations
                      thereof if other than $1,000 and any integral multiple

                      Securities of the series and vice versa (if permitted by
                      applicable laws and regulations), whether any Debt
                      Securities of the series are to be issuable initially in
                      temporary global form and whether any Debt Securities of

                      owners of interests in any such permanent Global Security
                      (as defined under "--Book-Entry System and Global
                      Securities") may exchange such interests for Debt
                      Securities of such series and of like tenor of any
                      authorized form and denomination and the circumstances
                      under which any such exchanges may occur, if other than in
                      the manner provided in the Indenture, and, if Registered

                      applicable Indenture, or any modification thereof;

              (18)    Whether and under what circumstances the Company will pay
                      any additional amounts on such Debt Securities in respect
                      of any tax, assessment or governmental charge and, if so,
                      whether the Company will have the option to redeem such
                      Debt Securities in lieu of making such payment;

              (19)    Any deletions from, modifications of or additions to the
                      events of default or covenants of the Company, to the
                      extent different from those described herein or set forth
                      in the applicable Indenture with respect to such Debt
                      Securities, and any change in the right of any Trustee or
                      any of the holders to declare the principal amount of any
                      of such Debt Securities due and payable; and

              (20)    Any other terms of such Debt Securities not inconsistent
                      with the provisions of the applicable Indenture.

        If so indicated in the applicable Prospectus Supplement, the Debt
Securities may be issued at a discount below their principal amount and provide
for less than the entire principal amount thereof to be payable upon declaration
of acceleration of the maturity thereof ("Original Issue Discount Securities").
In such cases, any special U.S. federal income tax, accounting and other
considerations applicable to Original Issue Discount Securities will be
described in the applicable Prospectus Supplement.

        Except as may be set forth in any Prospectus Supplement, the Debt
Securities will not contain any provisions that would limit the ability of the
Company to incur indebtedness or that would afford holders of Debt Securities
protection in the event of a highly leveraged or similar transaction involving
the Company or in the event of a change of control. Restrictions on ownership
and transfers of the Common Stock and Preferred Stock are designed to preserve
its status as a REIT and, therefore, may act to prevent or hinder a change of
control. See "Restrictions on Transfers of Capital Stock." Reference is made to
the applicable Prospectus Supplement for information with respect to any
deletions from, modifications of, or additions to, the events of


                                        7
<PAGE>   9
default or covenants of the Company that are described below, including any
addition of a covenant or other provision providing event risk or similar
protection.

DENOMINATION, INTEREST, REGISTRATION AND TRANSFER

        Unless otherwise described in the applicable Prospectus Supplement, the
Debt Securities of any series will be issuable in denominations of $1,000 and
integral multiples thereof.

        Unless otherwise specified in the applicable Prospectus Supplement, the
principal of (and applicable premium or Make-Whole Amount, if any) and interest
on any series of Debt Securities will be payable at the corporate trust office
of the applicable Trustee, the address of which will be stated in the applicable
Prospectus Supplement; provided that, at the option of the Company, payment of
interest may be made by check mailed to the address of the person entitled
thereto as it appears in the applicable register for such Debt Securities or by
wire transfer of funds to such person at an account maintained within the United
States.

        Any interest not punctually paid or duly provided for on any Interest
Payment Date with respect to a Debt Security in registered form ("Defaulted
Interest") will forthwith cease to be payable to the holder on the applicable
Regular Record Date and may either be paid to the Person in whose name such Debt
Security 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, in which case notice thereof shall be given to the holder of such
Debt Security not less than 10 days prior to such Special Record Date, or may be
paid at any time in any other lawful manner, all as more completely described in
the applicable Indenture.

        Subject to certain limitations imposed upon Debt Securities issued in
book-entry form, the Debt Securities of any series will be exchangeable for any
authorized denomination of other Debt Securities of the same series and of a
like aggregate principal amount and tenor upon surrender of such Debt Securities
at the corporate trust office of the applicable Trustee or at the office of any
transfer agent designated by the Company for such purpose. In addition, subject
to certain limitations imposed upon Debt Securities issued in book-entry form,
the Debt Securities of any series may be surrendered for conversion or
registration of transfer or exchange thereof at the corporate trust office of
the applicable Trustee or at the office of any transfer agent designated by the
Company for such purpose. Every Debt Security surrendered for conversion,
registration of transfer or exchange must be duly endorsed or accompanied by a
written instrument of transfer, and the person requesting such action must
provide evidence of title and identity satisfactory to the applicable Trustee or
transfer agent. No service charge will be made for any registration of transfer
or exchange of any Debt Securities, but the Company may require payment of a sum
sufficient to cover any tax or other governmental charge payable in connection
therewith. If the applicable Prospectus Supplement refers to any transfer agent
(in addition to the applicable Trustee) initially designated by the Company with
respect to any series of Debt Securities, the Company may at any time rescind
the designation of any such transfer agent or approve a change in the location
through which any such transfer agent acts, except that the Company will be
required to maintain a transfer agent in each place of payment for such series.
The Company may at any time designate additional transfer agents with respect to
any series of Debt Securities.

        Neither the Company nor any Trustee shall be required (i) to issue,
register the transfer of or exchange Debt Securities of any series during a
period beginning at the opening of business 15 days before the selection of any
Debt Securities for redemption and ending at the close of business on the day of
mailing of a notice of redemption; (ii) to register the transfer of or exchange
any Debt Security, or portion thereof, so selected for redemption, in whole or
in part, except the unredeemed portion of any Debt Security being redeemed in
part; or (iii) to issue, register the transfer of or exchange any Debt Security
that has been surrendered for repayment at the option of the holder, except the
portion, if any, of such Debt Security not to be so repaid.

MERGER, CONSOLIDATION OR SALE OF ASSETS

        The Indentures will provide that Company may, without the consent of the
holders of any outstanding Debt Securities, consolidate with, or sell, lease or
convey all or substantially all of its assets to, or merge with or into, any
other entity provided that (a) either the Company shall be the continuing
entity, or the successor entity (if other than the Company) formed by or
resulting from any such consolidation or merger or which shall have received the
transfer of such assets is organized under the laws of any domestic jurisdiction
and assumes the Company's obligations to pay principal of (and premium or
Make-Whole Amount, if any) and interest on all of the Debt Securities and the
due and punctual performance and observance of all of the covenants and
conditions contained in each Indenture; (b) immediately after giving effect to
such transaction and treating any indebtedness that becomes an obligation of the
Company or any subsidiary as a result thereof as having been incurred by the
Company or such subsidiary at the time of such transaction, no Event of Default
under the Indentures, and no event which, after notice or the lapse of time, or
both, would become such an Event of Default, shall have occurred and be
continuing; and (c) an officers' certificate and legal opinion covering such
conditions shall be delivered to each Trustee.

CERTAIN COVENANTS

        The applicable Prospectus Supplement will describe any material
covenants in respect of a series of Debt Securities that are not described in
this Prospectus. Unless otherwise indicated in the applicable Prospectus
Supplement, Senior Debt Securities will include the following covenants of the
Company:

        Existence. Except as permitted under "--Merger, Consolidation or Sale of
Assets," the Indentures will require the Company to do or cause to be done all
things necessary to preserve and keep in full force and effect its corporate
existence, rights (by articles of incorporation, by-laws and statute) and
franchises; provided, however, that the Company shall not be required to
preserve any right or franchise if its Board of Directors determines that the
preservation thereof is no longer desirable in the conduct of its business.

        Maintenance of Properties. The Indentures will require the Company to
cause all of its material properties used or useful in the conduct of its
business or the business of any subsidiary to be maintained and kept in good
condition, repair and working order and supplied with all necessary equipment
and will cause to be made all necessary repairs, renewals, replacements,
betterments and improvements thereof, all as in the judgment of the Company may
be necessary so that the business carried on in connection therewith may be
properly and advantageously conducted at all times; provided, however, that the
Company and its subsidiaries shall not be prevented from selling or otherwise
disposing of their properties for value in the ordinary course of business.

        Insurance. The Indentures will require the Company to cause each of its
and its subsidiaries' insurable properties to be insured against loss or damage
in an amount deemed reasonable by the Board of Directors with insurers of
recognized responsibility and, if described in the applicable Prospectus
Supplement, having a specified rating from a recognized insurance rating
service.

        Payment of Taxes and Other Claims. The Indentures will require the
Company to pay or discharge or cause to be paid or discharged, before the same
shall become delinquent, (i) all taxes, assessments and governmental charges
levied or imposed upon it or any subsidiary or upon the income, profits or
property of the Company or any subsidiary and (ii) all lawful claims for labor,
materials and supplies which, if unpaid, might by law become a lien upon the
property of the Company or any subsidiary unless such lien would not have a
material adverse effect upon such property; provided, however, that the Company
shall not be required to pay or discharge or cause to be paid or discharged any
such tax, assessment, charge or claim (i) whose amount, applicability or
validity is being contested in good faith or (ii) for which the Company has set
apart and maintains an adequate reserve.


                                        9
<PAGE>   11
        Provision of Financial Information. Whether or not the Company is
subject to Section 13 or 15(d) of the Exchange Act, the Indentures will require
the Company, within 15 days of each of the respective dates by which the Company
would have been required to file annual reports, quarterly reports and other
documents with the Commission if the Company were so subject, (i) to transmit by
mail to all holders of Debt Securities, as their names and addresses appear in
the applicable register for such Debt Securities, without cost to such holders,
copies of the annual reports, quarterly reports and other documents that the
Company would have been required to file with the Commission pursuant to Section
13 or 15(d) of the Exchange Act if the Company were subject to such sections,
(ii) to file with the applicable Trustee copies of the annual reports, quarterly
reports and other documents that the Company would have been required to file
with the Commission pursuant to Section 13 or 15(d) of the Exchange Act if the
Company were subject to such Sections and (iii) to supply, promptly upon written
request and payment of the reasonable cost of duplication and delivery, copies
of such documents to any prospective holder.

EVENTS OF DEFAULT, NOTICE AND WAIVER

        Unless otherwise described in the applicable Prospectus Supplement, each
Indenture will provide that the following events are "Events of Default" with
respect to any series of Debt Securities issued thereunder: (a) default in the
payment of any installment of interest on any Debt Security of such series when
such interest becomes due and payable that continues for a period of 30 days;
(b) default in the payment of principal of (or premium or Make-Whole Amount, if
any, on) any Debt Security of such series when due and payable; (c) default in
making any sinking fund payment as required for any Debt Security of such
series; (d) default in the performance or breach of any other covenant or
warranty of the Company contained in the Indenture (other than a covenant added
to the Indenture solely for the benefit of a series of Debt Securities issued
thereunder other than such series), continued for 60 days after written notice
as provided in the applicable Indenture; (e) a default under any bond,
debenture, note or other evidence of indebtedness for money borrowed by the
Company or any of its subsidiaries in an aggregate principal amount in excess of
$25,000,000 or under any mortgage, indenture or instrument under which there may
be issued or by which there may be secured or evidenced any indebtedness for
money borrowed by the Company or any of its subsidiaries in an aggregate
principal amount in excess of $25,000,000, whether such indebtedness exists on
the date of such Indenture or shall thereafter be created, which default shall
have resulted in such indebtedness becoming or being declared due and payable
prior to the date on which it would otherwise have become due and payable or
such obligations being accelerated, without such indebtedness having been
discharge or such acceleration having been rescinded or annulled within a
specified period of time; (f) certain events of bankruptcy, insolvency or
reorganization, or court appointment of a receiver, liquidator or trustee of the
Company or any Significant Subsidiary of the Company; and (g) any other event of
default provided with respect to a particular series of Debt Securities. The
term "Significant Subsidiary" has the meaning ascribed to such term in
Regulation S-X promulgated under the Securities Act.

        If an Event of Default under any Indenture with respect to any series of
Debt Securities at the time outstanding occurs and is continuing, then in every
such case the applicable Trustee or the holders of not less than 25% in
principal amount of the Debt Securities of that series will have the right to
declare the principal amount (or, if the Debt Securities of that series are
Original Issue Discount Securities or indexed securities, such portion of the
principal amount as may be specified in the terms thereof) of, and premium or
Make-Whole Amount, if any, on, all the Debt Securities of that series to be due
and payable immediately by written notice thereof to the Company (and to the
applicable Trustee if given by the holders). However, at any time after such a
declaration of acceleration with respect to Debt Securities of such series (or
of all Debt Securities then outstanding under any Indenture, as the case may be)
has been made, but before a judgment or decree for payment of the money due has
been obtained by the applicable Trustee, the holders of not less than a majority
in principal amount of outstanding Debt Securities of such series (or of all
Debt Securities then outstanding under the applicable Indenture, as the case may
be) may rescind and annul such declaration and its consequences if (a) the
Company shall have deposited with the applicable Trustee all required payments
of the principal of (and premium or Make-Whole Amount, if any) and interest on
the Debt Securities of such series (or of all Debt


                                       10
<PAGE>   12
Securities then outstanding under the applicable Indenture, as the case may be),
plus certain fees, expenses, disbursements and advances of the applicable
Trustee and (b) all Events of Default, other than the non-payment of accelerated
principal (or specified portion thereof and the premium or Make-Whole Amount, if
any), with respect to Debt Securities of such series (or of all Debt Securities
then outstanding under the applicable Indenture, as the case may be) have been
cured or waived as provided in such Indenture. The Indentures will also provide
that the holders of not less than a majority in principal amount of the
outstanding Debt Securities of any series (or of all Debt Securities then
outstanding under the applicable Indenture, as the case may be) may waive any
past default with respect to such series and its consequences, except a default
(x) in the payment of the principal of (or premium or Make-Whole Amount, if any)
or interest on any Debt Security of such series or (y) in respect of a covenant
or provision contained in the applicable Indenture that cannot be modified or
amended without the consent of the holder of each outstanding Debt Security
affected thereby.

        The Indentures will require each Trustee to give notice to the holders
of Debt Securities within 90 days of a default under the applicable Indenture
unless such default shall have been cured or waived; provided, however, that
such Trustee may withhold notice to the holders of any series of Debt Securities
of any default with respect to such series (except a default in the payment of
the principal of (or premium or Make-Whole Amount, if any) or interest on any
Debt Security of such series or in the payment of any sinking fund installment
in respect of any Debt Security of such series) if specified responsible
officers of such Trustee consider such withholding to be in the interest of such
holders.

        The Indentures will provide that no holders of Debt Securities of any
series may institute any proceedings, judicial or otherwise, with respect to
such Indenture or for any remedy thereunder, except in the case of failure of
the applicable Trustee, for 60 days, to act after it has received a written
request to institute proceedings in respect of an Event of Default from the
holders of not less than 25% in principal amount of the outstanding Debt
Securities of such series, as well as an offer of indemnity reasonably
satisfactory to it. This provision will not prevent, however, any holder of Debt
Securities from instituting suit for the enforcement of payment of the principal
of (and premium or Make-Whole Amount, if any) and interest on such Debt
Securities at the respective due dates or redemption dates thereof.

        The Indentures will provide that, subject to provisions in each
Indenture relating to its duties in case of default, a Trustee will be under no
obligation to exercise any of its rights or powers under an Indenture at the
request or direction of any holders of any series of Debt Securities then
outstanding under such Indenture, unless such holders shall have offered to the
Trustee thereunder reasonable security or indemnity. The holders of not less
than a majority in principal amount of the outstanding Debt Securities of any
series (or of all Debt Securities then outstanding under an Indenture, as the
case may be) shall have the right to direct the time, method and place of
conducting any proceeding for any remedy available to the applicable Trustee, or
of exercising any trust or power conferred upon such Trustee. However, a Trustee
may refuse to follow any direction which is in conflict with any law or the
applicable Indenture, which may involve such Trustee in personal liability or
which may be unduly prejudicial to the holders of Debt Securities of such series
not joining therein.

        Within 120 days after the close of each fiscal year, the Company will be
required to deliver to each Trustee a certificate, signed by one of several
specified officers of the Company, stating whether or not such officer has
knowledge of any default under the applicable Indenture and, if so, specifying
each such default and the nature and status thereof.

MODIFICATION OF THE INDENTURES

        Modifications and amendments of an Indenture will be permitted to be
made only with the consent of the holders of not less than a majority in
principal amount of all outstanding Debt Securities issued under such Indenture
affected by such modification or amendment; provided, however, that no such
modification or amendment may, without the consent of the holder of each such
Debt Security affected thereby, (a) change the


                                       11
<PAGE>   13
stated maturity of the principal of, or any installment of interest (or premium
or Make-Whole Amount, if any) on, any such Debt Security; (b) reduce the
principal amount of, or the rate or amount of interest on, or any premium
payable on redemption of, any such Debt Security, or reduce the amount of
principal of an Original Issue Discount Security that would be due and payable
upon declaration of acceleration of the maturity thereof or would be provable in
bankruptcy, or adversely affect any right of repayment of the holder of any such
Debt Security; (c) change the place of payment, or the coin or currency, for
payment of principal of, premium or Make-Whole Amount, if any, or interest on
any such Debt Security; (d) impair the right to institute suit for the
enforcement of any payment on or with respect to any such Debt Security; (e)
reduce the above-stated percentage of outstanding Debt Securities of any series
necessary to modify or amend the applicable Indenture, to waive compliance with
certain provisions thereof or certain defaults and consequences thereunder or to
reduce the quorum or voting requirements set forth in the applicable Indenture;
or (f) modify any of the foregoing provisions or any of the provisions relating
to the waiver of certain past defaults or certain covenants, except to increase
the required percentage to effect such action or to provide that certain other
provisions may not be modified or waived without the consent of the holder of
such Debt Security.

        The holders of a majority in aggregate principal amount of the
outstanding Debt Securities of each series may, on behalf of all holders of Debt
Securities of that series, waive, insofar as that series is concerned,
compliance by the Company with certain restrictive covenants of the applicable
Indenture.

        Modifications and amendments of an Indenture will be permitted to be
made by the Company and the respective Trustee thereunder without the consent of
any holder of Debt Securities for any of the following purposes: (i) to evidence
the succession of another person to the Company as obligor under such Indenture;
(ii) to add to the covenants of the Company for the benefit of the holders of
all or any series of Debt Securities or to surrender any right or power
conferred upon the Company in such Indenture; (iii) to add events of default for
the benefit of the holders of all or any series of Debt Securities; (iv) to add
or change any provisions of an Indenture to facilitate the issuance of, or to
liberalize certain terms of, Debt Securities in bearer form, or to permit or
facilitate the issuance of Debt Securities in uncertificated form, provided that
such action shall not adversely affect the interests of the holders of the Debt
Securities of any series in any material respect; (v) to change or eliminate any
provisions of an Indenture, provided that any such change or elimination shall
become effective only when there are no Debt Securities outstanding of any
series created prior thereto which are entitled to the benefit of such
provision; (vi) to secure the Debt Securities; (vii) to establish the form or
terms of Debt Securities of any series, including the provisions and procedures,
if applicable, for the conversion of such Debt Securities into Common Stock or
Preferred Stock; (viii) to provide for the acceptance of appointment by a
successor Trustee or facilitate the administration of the trusts under an
Indenture by more than one Trustee; (ix) to cure any ambiguity, defect or
inconsistency in an Indenture, provided that such action shall not adversely
affect the interests of holders of Debt Securities of any series issued under
such Indenture; or (x) to supplement any of the provisions of an Indenture to
the extent necessary to permit or facilitate defeasance and discharge of any
series of such Debt Securities, provided that such action shall not adversely
affect the interests of the holders of the outstanding Debt Securities of any
series in any material respect.

        The Indentures will provide that in determining whether the holders of
the requisite principal amount of outstanding Debt Securities of a series have
given any request, demand, authorization, direction, notice, consent or waiver
thereunder or whether a quorum is present at a meeting of holders of Debt
Securities, (i) the principal amount of an Original Issue Discount Security that
shall be deemed to be outstanding shall be the amount of the principal thereof
that would be due and payable as of the date of such determination upon
declaration of acceleration of the maturity thereof, (ii) the principal amount
of any Debt Security denominated in a foreign currency that shall be deemed
outstanding shall be the U.S. dollar equivalent, determined on the issue date
for such Debt Security, of the principal amount (or, in the case of an Original
Issue Discount Security, the U.S. dollar equivalent on the issue date of such
Debt Security of the amount determined as provided in (i) above), (iii) the
principal amount of an indexed security that shall be deemed outstanding shall
be the principal face amount of such indexed security at original issuance,
unless otherwise provided with respect to such indexed


                                       12
<PAGE>   14
security pursuant such Indenture, and (iv) Debt Securities owned by the Company
or any other obligor upon the Debt Securities or any affiliate of the Company or
of such other obligor shall be disregarded.

        The Indentures will contain provisions for convening meetings of the
holders of Debt Securities of a series. A meeting will be permitted to be called
at any time by the applicable Trustee, and also, upon request, by the Company or
 the holders of at least 25% in principal amount of the outstanding Debt
Securities of such series, in any such case upon notice given as provided in
such Indenture. Except for any consent that must be given by the holder of each
Debt Security affected by certain modifications and amendments of an Indenture,
any resolution presented at a meeting or adjourned meeting duly reconvened at
which a quorum is present may be adopted by the affirmative vote of the holders
of a majority in principal amount of the outstanding Debt Securities of that
series; provided, however, that, except as referred to above, any resolution
with respect to any request, demand, authorization, direction, notice, consent,
waiver or other action that may be made, given or taken by the holders of a
specified percentage, which is less than a majority, in principal amount of the
outstanding Debt Securities of a series may be adopted at a meeting or adjourned
meeting duly reconvened at which a quorum is present by the affirmative vote of
the holders of such specified percentage in principal amount of the outstanding
Debt Securities of that series. Any resolution passed or decision taken at any
meeting of holders of Debt Securities of any series duly held in accordance with
an Indenture will be binding on all holders of Debt Securities of that series.
The quorum at any meeting called to adopt a resolution, and at any reconvened
meeting, will be persons holding or representing a majority in principal amount
of the outstanding Debt Securities of a series; provided, however, that if any
action is to be taken at such meeting with respect to a consent or waiver which
may be given by the holders of not less than a specified percentage in principal
amount of the outstanding Debt Securities of a series, the persons holding or
representing such specified percentage in principal amount of the outstanding
Debt Securities of such series will constitute a quorum.

        Notwithstanding the foregoing provisions, the Indentures will provide
that if any action is to be taken at a meeting of holders of Debt Securities of
any series with respect to any request, demand, authorization, direction,
notice, consent, waiver and other action that such Indenture expressly provides
may be made, given or taken by the holders of a specified percentage in
principal amount of all outstanding Debt Securities affected thereby, or of the
holders of such series and one or more additional series: (i) there shall be no
minimum quorum requirement for such meeting, and (ii) the principal amount of
the outstanding Debt Securities of such series that vote in favor of such
request, demand, authorization, direction, notice, consent, waiver or other
action shall be taken into account in determining whether such request, demand,
authorization, direction, notice, consent, waiver or other action has been made,
given or taken under such Indenture.

SUBORDINATION

        Unless otherwise provided in the applicable Prospectus Supplement,
Subordinated Securities will be subject to the following subordination
provisions.

        Upon any distribution to creditors of the Company in a liquidation,
dissolution or reorganization, the payment of the principal of and interest on
any Subordinated Securities will be subordinated to the extent provided in the
applicable Indenture in right of payment to the prior payment in full of all
Senior Debt (as defined below), but the obligation of the Company to make
payments of the principal of and interest on such Subordinated Securities will
not otherwise be affected. No payment of principal or interest will be permitted
to be made on Subordinated Securities at any time if a default on Senior Debt
exists that permits the holders of such Senior Debt to accelerate its maturity
and the default is the subject of judicial proceedings or the Company receives
notice of the default. After all Senior Debt is paid in full and until the
Subordinated Securities are paid in full, holders will be subrogated to the
rights of holders of Senior Debt to the extent that distributions otherwise
payable to holders have been applied to the payment of Senior Debt. The
Subordinated Indenture will not restrict the amount of Senior Indebtedness or
other indebtedness of the Company and its subsidiaries. As a result of these
subordination provisions, in the event of a distribution of assets upon
insolvency, holders of Subordinated Indebtedness may recover less, ratably, than
general creditors of the Company.

 
                                       13
<PAGE>   15
        Senior Debt will be defined in the applicable Indenture as the principal
of and interest on, or substantially similar payments to be made by the Company
in respect of, the following, whether outstanding at the date of execution of
the applicable Indenture or thereafter incurred, created or assumed: (a)
indebtedness of the Company for money borrowed or represented by purchase-money
obligations, (b) indebtedness of the Company evidenced by notes, debentures, or
bonds, or other securities issued under the provisions of an indenture, fiscal
agency agreement or other agreement, (c) obligations of the Company as lessee
under leases of property either made as part of any sale and leaseback
transaction to which the Company is a party or otherwise, (d) indebtedness of
partnerships and joint ventures which is included in the consolidated financial
statements of the Company, (e) indebtedness, obligations and liabilities of
others in respect of which the Company is liable contingently or otherwise to
pay or advance money or property or as guarantor, endorser or otherwise or which
the Company has agreed to purchase or otherwise acquire, and (f) any binding
commitment of the Company to fund any real estate investment or to fund any
investment in any entity making such real estate investment, in each case other
than (1) any such indebtedness, obligation or liability referred to in clauses
(a) through (f) above as to which, in the instrument creating or evidencing the
same pursuant to which the same is outstanding, it is provided that such
indebtedness, obligation or liability is not superior in right of payment to the
Subordinated Securities or ranks pari passu with the Subordinated Securities,
(2) any such indebtedness, obligation or liability which is subordinated to
indebtedness of the Company to substantially the same extent as or to a greater
extent than the Subordinated Securities are subordinated, and (3) the
Subordinated Securities. There will not be any restrictions in any Indenture
relating to Subordinated Securities upon the creation of additional Senior Debt.

        If this Prospectus is being delivered in connection with a series of
Subordinated Securities, the accompanying Prospectus Supplement or the
information incorporated herein by reference will set forth the approximate
amount of Senior Debt outstanding as of the end of the Company's most recent
fiscal quarter.

DISCHARGE, DEFEASANCE AND COVENANT DEFEASANCE

        Unless otherwise indicated in the applicable Prospectus Supplement, the
Company will be permitted, at its option, to discharge certain obligations to
holders of any series of Debt Securities issued under any Indenture that have
not already been delivered to the applicable Trustee for cancellation and that
either have become due and payable or will become due and payable within one
year (or scheduled for redemption within one year) by irrevocably depositing
with the applicable Trustee, in trust, funds in such currency or currencies,
currency unit or units or composite currency or currencies in which such Debt
Securities are payable in an amount sufficient to pay the entire indebtedness on
such Debt Securities in respect of principal (and premium or Make-Whole Amount,
if any) and interest to the date of such deposit (if such Debt Securities have
become due and payable) or to the stated maturity or redemption date, as the
case may be.

        The Indentures will provide that, unless otherwise indicated in the
applicable Prospectus Supplement, the Company may elect either (a) to defease
and be discharged from any and all obligations with respect to such Debt
Securities (except for the obligation to pay additional amounts, if any, upon
the occurrence of certain events of tax, assessment or governmental charge with
respect to payments on such Debt Securities and the obligations to register the
transfer or exchange of such Debt Securities, to replace temporary or mutilated,
destroyed, lost or stolen Debt Securities, to maintain an office or agency in
respect of such Debt Securities, to hold moneys for payment in trust and, with
respect to Subordinated Debt Securities which are convertible or exchangeable,
the right to convert or exchange) ("defeasance") or (b) to be released from its
obligations with respect to such Debt Securities under the applicable Indenture
(including the restrictions described under "--Certain Covenants") or, if
provided in the applicable Prospectus Supplement, its obligations with respect
to any other covenant, and any omission to comply with such obligations shall
not constitute an Event of Default with respect to such Debt Securities
("covenant defeasance"), in either case upon the irrevocable deposit by the
Company with the applicable Trustee, in trust, of an amount, in such currency or
currencies, currency unit or units or composite currency or currencies in which
such Debt Securities are payable at stated maturity, or Government Obligations
(as defined below), or both, applicable to such Debt Securities, which through
the

                                       14
<PAGE>   16
scheduled payment of principal and interest in accordance with their terms will
provide money in an amount sufficient to pay the principal of (and premium or
Make-Whole Amount, if any) and interest on such Debt Securities, and any
mandatory sinking fund or analogous payments thereon, on the scheduled due dates
therefor.

        Such a trust will only be permitted to be established if, among other
things, the Company has delivered to the applicable Trustee an opinion of
counsel (as specified in the applicable Indenture) to the effect that the
holders of such Debt Securities will not recognize income, gain or loss for U.S.
federal income tax purposes as a result of such defeasance or covenant
defeasance and will be subject to U.S. federal income tax on the same amounts,
in the same manner and at the same times as would have been the case if such
defeasance or covenant defeasance had not occurred, and such opinion of counsel,
in the case of defeasance, will be required to refer to and be based upon a
ruling received from or published by the Internal Revenue Service or a change in
applicable United States federal income tax law occurring after the date of the
Indenture. In the event of such defeasance, the holders of such Debt Securities
would thereafter be able to look only to such trust fund for payment of
principal (and premium or Make-Whole Amount, if any) and interest.

        "Government Obligations" means securities that are (i) direct
obligations of the United States of America or the government which issued the
foreign currency in which the Debt Securities of a particular series are
payable, for the payment of which its full faith and credit is pledged or (ii)
obligations of a person controlled or supervised by and acting as an agency or
instrumentality of the United States of America or such government which issued
the foreign currency in which the Debt Securities of such series are payable,
the payment of which is unconditionally guaranteed as a full faith and credit
obligation by the United States of America or such other government, which, in
either case, are not callable or redeemable at the option of the issuer thereof,
and shall also include a depository receipt issued by a bank or trust company as
custodian with respect to any such Government obligation or a specific payment
of interest on or principal of any such Government Obligation held by such
custodian for the account of the holder of a depository receipt, provided that
(except as required by law) such custodian is not authorized to make any
deduction from the amount payable to the holder of such depository receipt from
any amount received by the custodian in respect of the Government Obligation or
the specific payment of interest on or principal of the Government Obligation
evidenced by such depository receipt.

        Unless otherwise indicated in the applicable Prospectus Supplement, if
after the Company has deposited funds and/or Government Obligations to effect
defeasance or covenant defeasance with respect to Debt Securities of any series,
(a) the holder of a Debt Security of such series is entitled to, and does, elect
pursuant to the applicable Indenture or the terms of such Debt Security to
receive payment in a currency, currency unit or composite currency other than
that in which such deposit has been made in respect of such Debt Security, or
(b) a Conversion Event (as defined below) occurs in respect of the currency,
currency unit or composite currency in which such deposit has been made, the
indebtedness represented by such Debt Security will be deemed to have been, and
will be, fully discharged and satisfied through the payment of the principal of
(and premium or Make-Whole Amount, if any) and interest on such Debt Security as
they become due out of the proceeds yielded by converting the amount so
deposited in respect of such Debt Security into the currency, currency unit or
composite currency in which such Debt Security becomes payable as a result of
such election or such cessation of usage based on the applicable market exchange
rate. "Conversion Event" means the cessation of use of (i) a currency, currency
unit or composite currency both by the government of the country which issued
such currency and for the settlement of transactions by a central bank or other
public institutions of or within the international banking community, (ii) the
ECU both within the European Monetary System and for the settlement of
transactions by public institutions of or within the European Communities or
(iii) any currency unit or composite currency other than the ECU for the
purposes for which it was established. Unless otherwise indicated in the
applicable Prospectus Supplement, all payments of principal of (and premium, if
any) and interest on any Debt Security that is payable in a foreign currency
that ceases to be used by its government of issuance shall be made in U.S.
dollars.

        In the event the Company effects covenant defeasance with respect to any
Debt Securities and such Debt Securities are declared due and payable because of
the occurrence of any Event of Default other than the Event


                                       15
<PAGE>   17
of Default described in clause (d) under "--Events of Default, Notice and
Waiver" with respect to specified sections of an Indenture (which sections would
no longer be applicable to such Debt Securities) or described in clause (g)
under "--Events of Default, Notice and Waiver" with respect to any other
covenant as to which there has been covenant defeasance, the amount in such
currency, currency unit or composite currency in which such Debt Securities are
payable, and Government Obligations on deposit with the applicable Trustee, will
be sufficient to pay amounts due on such Debt Securities at the time of their
stated maturity but may not be sufficient to pay amounts due on such Debt
Securities at the time of the acceleration resulting from such Event of Default.
However, the Company would remain liable to make payment of such amounts due at
the time of acceleration.

        The applicable Prospectus Supplement may further describe the
provisions, if any, permitting such defeasance or covenant defeasance, including
any modifications to the provisions described above, with respect to the Debt
Securities of or within a particular series.

CONVERSION RIGHTS

        The terms and conditions, if any, upon which the Debt Securities are
convertible into Common Stock or Preferred Stock will be set forth in the
applicable Prospectus Supplement relating thereto. Such terms will include
whether such Debt Securities are convertible into shares of Common Stock or
Preferred Stock, the conversion price (or manner of calculation thereof), the
conversion period, provisions as to whether conversion will be at the option of
the holders or the Company, the events requiring an adjustment of the conversion
price and provisions affecting conversion in the event of the redemption of such
Debt Securities and any restrictions on conversion, including restrictions
directed at maintaining the Company's REIT status.

PAYMENT

        Unless otherwise specified in the applicable Prospectus Supplement, the
principal of (and applicable premium or Make-Whole Amount, if any) and interest
on any series of Debt Securities will be payable at the corporate trust office
of the Trustee, the address of which will be stated in the applicable Prospectus
Supplement; provided that, at the option of the Company, payment of interest may
be made by check mailed to the address of the person entitled thereto as it
appears in the applicable register for such Debt Securities or by wire transfer
of funds to such person at an account maintained within the United States.

        All moneys paid by the Company to a paying agent or a Trustee for the
payment of the principal of or any premium or interest on any Debt Security
which remain unclaimed at the end of two years after such principal, premium or
interest has become due and payable will be repaid to the Company, and the
holder of such Debt Security thereafter may look only to the Company for payment
thereof.

BOOK-ENTRY SYSTEM AND GLOBAL SECURITIES

        The Debt Securities of a series may be issued in whole or in part in the
form of one or more global securities ("Global Securities") that will be
deposited with, or on behalf of, a depository (the "Depository") identified in
the Prospectus Supplement relating to such series. Global Securities, if any,
issued in the United States are expected to be deposited with The Depository
Trust Company ("DTC"), as Depository. Global Securities may be issued in either
fully registered or bearer form and in either temporary or permanent form.
Unless and until it is exchanged in whole or in part for the individual Debt
Securities represented thereby, a Global Security may not be transferred except
as a whole by the Depository for such Global Security to a nominee of such
Depository or by a nominee of such Depository to such Depository or another
nominee of such Depository or by such Depository or any nominee of such
Depositor to a successor Depository or any nominee of such successor.


                                       16
<PAGE>   18
        The specific terms of the depository arrangement with respect to a
series of Debt Securities will be described in the Prospectus Supplement
relating to such series. The Company expects that unless otherwise indicated in
the applicable Prospectus Supplement, the following provisions will apply to
depository arrangements.

        Upon the issuance of a Global Security, the Depository for such Global
Security or its nominee will credit on its book-entry registration and transfer
system the respective principal amounts of the individual Debt Securities
represented by such Global Security to the accounts of persons that have
accounts with such Depository ("Participants"). Such accounts shall be
designated by the underwriters, dealers or agents with respect to such Debt
Securities or by the Company if such Debt Securities are offered directly by the
Company. Ownership of beneficial interests in such Global Security will be
limited to Participants or persons that may hold interests through Participants.

        The Company expects that, pursuant to procedures established by DTC,
ownership of beneficial interests in any Global Security with respect to which
DTC is the Depository will be shown on, and the transfer of that ownership will
be effected only through, records maintained by DTC or its nominee (with respect
to beneficial interests of Participants) and records of Participants (with
respect to beneficial interests of persons who hold through Participants).
Neither the Company nor the Trustee will have any responsibility or liability
for any aspect of the records of DTC or for maintaining, supervising or
reviewing any records of DTC or any of its Participants relating to beneficial
ownership interests in the Debt Securities. The laws of some states require that
certain purchasers of securities take physical delivery of such securities in
definitive form. Such limits and laws may impair the ability to own, pledge or
transfer beneficial interest in a Global Security.

        So long as the Depository for a Global Security or its nominee is the
registered owner of such Global Security, such Depository or such nominee, as
the case may be, will be considered the sole owner or holder of the Debt
Securities represented by such Global Security for all purposes under the
applicable Indenture. Except as described below or in the applicable Prospectus
Supplement, owners of beneficial interest in a Global Security will not be
entitled to have any of the individual Debt Securities represented by such
Global Security registered in their names, will not receive or be entitled to
receive physical delivery of any such Debt Securities in definitive form and
will not be considered the owners or holders thereof under the applicable
Indenture. Beneficial owners of Debt Securities evidenced by a Global Security
will not be considered the owners or holders thereof under the applicable
Indenture for any purpose, including with respect to the giving of any
direction, instructions or approvals to the Trustee thereunder. Accordingly,
each person owning a beneficial interest in a Global Security with respect to
which DTC is the Depository must rely on the procedures of DTC and, if such
person is not a Participant, on the procedures of the Participant through which
such person owns its interests, to exercise any rights of a holder under the
applicable Indenture. The Company understands that, under existing industry
practice, if it requests any action of holders or if an owner of a beneficial
interest in a Global Security desires to give or take any action which a holder
is entitled to give or take under the applicable Indenture, DTC would authorize
the Participants holding the relevant beneficial interest to give or take such
action, and such Participants would authorize beneficial owners through such
Participants to give or take such actions or would otherwise act upon the
instructions of beneficial owners holding through them.

        Payments of principal of (and applicable premium or Make-Whole Amount,
if any) and interest on individual Debt Securities represented by a Global
Security registered in the name of a Depository or its nominee will be made to
or at the direction of the Depository or its nominee, as the case may be, as the
registered owner of the Global Security under the applicable Indenture. Under
the terms of the applicable Indenture, the Company and the Trustee may treat the
persons in whose name Debt Securities, including a Global Security, are
registered as the owners thereof for the purpose of receiving such payments.
Consequently, neither the Company nor the Trustee has or will have any
responsibility or liability for the payment of such amounts to beneficial owners
of Debt Securities (including principal, premium or Make-Whole Amount, if any,
and interest). The Company believes, however, that it is currently the policy of
DTC to immediately credit the accounts of relevant Participants with such
payments, in amounts proportionate to their


                                       17
<PAGE>   19
respective holdings of beneficial interests in the relevant Global Security as
shown on the records of DTC or its nominee. The Company also expects that
payments by Participants to owners of beneficial interests in such Global
Security held through such Participants will be governed by standing
instructions and customary practices, as is the case with securities held for
the account of customers in bearer form or registered in street name, and will
be the responsibility of such Participants. Redemption notices with respect to
any Debt Securities represented by a Global Security will be sent to the
Depository or its nominee. If less than all of the Debt Securities of any series
are to be redeemed, the Company expects the Depository to determine the amount
of the interest of each Participant in such Debt Securities to be redeemed to be
determined by lot. None of the Company, the Trustee, any Paying Agent or the
Security Registrar for such Debt Securities will have any responsibility or
liability for any aspect of the records relating to or payments made on account
of beneficial ownership interests in the Global Security for such Debt
Securities or for maintaining any records with respect thereto.

        Neither the Company nor the Trustee will be liable for any delay by the
holders of a Global Security or the Depository in identifying the beneficial
owners of Debt Securities and the Company and the Trustee may conclusively rely
on, and will be protected in relying on, instructions from the holder of a
Global Security or the Depository for all purposes. The rules applicable to DTC
and its Participants are on file with the Commission.

        If a Depository for any Debt Securities is at any time unwilling, unable
or ineligible to continue as depository and a successor depository is not
appointed by the Company within 90 days, the Company will issue individual Debt
Securities in exchange for the Global Security representing such Debt
Securities. In addition, the Company may at any time and in its sole discretion,
subject to any limitations described in the Prospectus Supplement relating to
such Debt Securities, determine not to have any of such Debt Securities
represented by one or more Global Securities and in such event will issue
individual Debt Securities in exchange for the Global Security or Securities
representing such Debt Securities. Individual Debt Securities so issued will be
issued in denominations of $1,000 and integral multiples thereof.

        The Debt Securities of a series may also be issued in whole or in part
in the form of one or more bearer global securities (a "Bearer Global Security")
that will be deposited with a depository, or with a nominee for such depository,
identified in the applicable Prospectus Supplement. Any such Bearer Global
Securities may be issued in temporary or permanent form. The specific terms and
procedures, including the specific terms of the depository arrangement, with
respect to any portion of a series of Debt Securities to be represented by one
or more Bearer Global Securities will be described in the applicable Prospectus
Supplement.


                         DESCRIPTION OF PREFERRED STOCK

        The description of the Company's Preferred Stock set forth below does
not purport to be complete and is qualified in its entirety by reference to the
Company's Articles of Incorporation and Bylaws, as amended (the "Bylaws").

GENERAL

        Under the Company's Articles of Incorporation, the Company has authority
to issue twenty-five (25) million shares of Preferred Stock, of which 2,308,800
shares have been designated Series A Preferred Stock and are currently
outstanding, 405,022 shares have been designated Series B Preferred Stock and
are currently outstanding and 2,300,000 shares have been designated Series C
Preferred Stock and are currently outstanding. The Series C Preferred Stock is
listed on the NYSE and the PCX under the symbol "BYA pc." Shares of Preferred
Stock may be issued from time to time, in one or more series, as authorized by
the Board of Directors of the Company. Prior to the issuance of shares of each
series, the Board of Directors is required by the MGCL, and the Company's
Articles of Incorporation, to fix for each series, subject to the provisions of
the

                                       18
<PAGE>   20
Company's Articles of Incorporation regarding excess stock, $.01 par value per
share ("Excess Stock"), the terms, preferences, conversion or other rights,
voting powers, restrictions, limitations as to dividends or other distributions,
qualifications and terms or conditions of redemption, as are permitted by
Maryland law. The Preferred Stock will, when issued following the receipt of
full consideration therefor, be fully paid and nonassessable and will have no
preemptive rights. The Board of Directors could authorize the issuance of shares
of Preferred Stock with terms and conditions that could have the effect of
discouraging a takeover or other transactions that holders of Common Stock might
believe to be in their best interests or in which holders of some, or a
majority, of the shares of Common Stock might receive a premium for their shares
over the then market price of such shares of Common Stock.

TERMS

        The following description of the Preferred Stock sets forth certain
general terms and provisions of the Preferred Stock to which any Prospectus
Supplement may relate. The statements below describing the Preferred Stock are
in all respects subject to and qualified in their entirety by reference to the
applicable provisions of the Company's Articles of Incorporation and Bylaws and
any applicable amendment to the Articles of Incorporation designating terms of a
series of Preferred Stock (a "Designating Amendment").

                      Preferred Stock;

                      exchange;

               (9)    The terms and conditions, if applicable, upon which such

                      thereof);

               (10)   Any other specific terms, preferences, rights, limitations
                      or restrictions of such Preferred Stock;

               (13)   Any limitations on issuance of any series of Preferred

                      liquidation, dissolution or winding up of the affairs of
                      the Company; and

               (14)   Any limitations on direct or beneficial ownership and
                      restrictions on transfer, in each case as may be
                      appropriate to preserve the status of the Company as a
                      REIT.

RANK

        Unless otherwise specified in the Prospectus Supplement, the Preferred
Stock will, with respect to dividend rights and rights upon liquidation,
dissolution or winding up of the Company, rank (i) senior to all classes or
series of Common Stock of the Company, and to all equity securities ranking
junior to such Preferred Stock with respect to dividend rights or rights upon
liquidation, dissolution or winding up of the Company; (ii) on a parity with all
equity securities issued by the Company the terms of which specifically provide
that such equity securities rank on a parity with the Preferred Stock with
respect to dividend rights or rights upon liquidation, dissolution or winding up
of the Company; and (iii) junior to all equity securities issued by the Company
the terms of which specifically provide that such equity securities rank senior
to the Preferred Stock with respect to dividend rights or rights upon
liquidation, dissolution or winding up of the Company. The term "equity
securities" does not include convertible debt securities.

DIVIDENDS

        Holders of the Preferred Stock of each series will be entitled to
receive, when, as and if declared by the Board of Directors of the Company, out
of assets of the Company legally available for payment, cash dividends at such
rates and on such dates as will be set forth in the applicable Prospectus
Supplement. Each such dividend shall be payable to holders of record as they
appear on the stock transfer books of the Company on such record dates as shall
be fixed by the Board of Directors of the Company.

        Dividends on any series of the Preferred Stock may be cumulative or
non-cumulative, as provided in the applicable Prospectus Supplement. Dividends,
if cumulative, will be cumulative from and after the date set forth in the
applicable Prospectus Supplement. If the Board of Directors of the Company fails
to declare a dividend payable on a dividend payment date on any series of the
Preferred Stock for which dividends are non-cumulative, then the holders of such
series of the Preferred Stock will have no right to receive a dividend in
respect of the dividend period ending on such dividend payment date, and the
Company will have no obligation to pay the dividend accrued for such period,
whether or not dividends on such series are declared payable on any future
dividend payment date.

        If Preferred Stock of any series is outstanding, no dividends will be
declared or paid or set apart for payment on any Common Stock of the Company or
any other series of Preferred Stock ranking, as to dividends, on a parity with
or junior to the Preferred Stock of such series for any period unless (i) if
such series of Preferred Stock has a cumulative dividend, full cumulative
dividends have been or contemporaneously are declared and paid or declared and a
sum sufficient for the payment thereof is set apart for such payment on the
Preferred Stock of such series for all past dividend periods and the then
current dividend period, or (ii) if such series of Preferred Stock does not have
a cumulative dividend, full dividends for the then current dividend period have
been or contemporaneously are declared and paid or declared and a sum sufficient
for the payment thereof is set apart for such payment on the Preferred Stock of
such series. When dividends are not paid in full (and a sum sufficient for such
full payment is not so set apart) upon Preferred Stock of any series and the
shares of any other series of Preferred Stock ranking on a parity as to
dividends with the Preferred Stock of such series, all dividends declared upon
Preferred Stock of such series and any other series of Preferred Stock ranking
on a parity as to dividends with such Preferred Stock shall be declared pro rata
so that the amount of dividends declared per share of Preferred Stock of such
series and such other series of Preferred Stock shall in all cases bear to each
other the same ratio that accrued dividends per share on the Preferred Stock of
such series

                                       20
<PAGE>   22
(which shall not include any accumulation in respect of unpaid dividends for
prior dividend periods if such Preferred Stock does not have a cumulative
dividend) and such other series of Preferred Stock bear to each other. No
interest, or sum of money in lieu of interest, shall be payable in respect of
any dividend payment or payments on Preferred Stock of such series which may be
in arrears.

        Except as provided in the immediately preceding paragraph, unless (i) if
such series of Preferred Stock has a cumulative dividend, full cumulative
dividends on the Preferred Stock of such series have been or contemporaneously
are declared and paid or declared and a sum sufficient for the payment thereof
is set apart for payment for all past dividend periods and the then current
dividend period, or (ii) if such series of Preferred Stock does not have a
cumulative dividend, full dividends on the Preferred Stock of such series have
been or contemporaneously are declared and paid or declared and a sum sufficient
for the payment thereof is set apart for payment for the then current dividend
period, no dividends (other than in shares of Common Stock or other shares of
capital stock ranking junior to the Preferred Stock of such series as to
dividends and upon liquidation) shall be declared or paid or set aside for
payment nor shall any other distribution be declared or made upon the Common
Stock, or any other capital stock of the Company ranking junior to or on a
parity with the Preferred Stock of such series as to dividends or upon
liquidation, nor shall any shares of Common Stock, or any other shares of
capital stock of the Company ranking junior to or on a parity with the Preferred
Stock of such series as to dividends or upon liquidation be redeemed, purchased
or otherwise acquired for any consideration (or any moneys be paid to or made
available for a sinking fund for the redemption of any such shares) by the
Company (except by conversion into or exchange for other capital stock of the
Company ranking junior to the Preferred Stock of such series as to dividends and
upon liquidation).

        Any dividend payment made on shares of a series of Preferred Stock shall
first be credited against the earliest accrued but unpaid dividend due with
respect to shares of such series which remains payable.

REDEMPTION

        If so indicated in the applicable Prospectus Supplement, the Preferred
Stock will be subject to mandatory redemption or redemption at the option of the
Company, as a whole or in part, in each case upon the terms, at the times and at
the redemption prices set forth in such Prospectus Supplement.

        The Prospectus Supplement relating to a series of Preferred Stock that
is subject to mandatory redemption will specify the number of shares of such
Preferred Stock that shall be redeemed by the Company in each year commencing
after a date to be specified, at a redemption price per share to be specified,
together with an amount equal to all accrued and unpaid dividends thereon (which
shall not, if such Preferred Stock does not have a cumulative dividend, include
any accumulation in respect of unpaid dividends for prior dividend periods) to
the date of redemption. The redemption price may be payable in cash or other
property, as specified in the applicable Prospectus Supplement. If the
redemption price for Preferred Stock of any series is payable only from the net
proceeds of the issuance of shares of capital stock of the Company, then the
terms of such Preferred Stock may provide that, if no such shares of capital
stock shall have been issued or to the extent the net proceeds from any issuance
are insufficient to pay in full the aggregate redemption price then due, then
such Preferred Stock shall automatically and mandatorily be converted into the
applicable shares of capital stock of the Company pursuant to conversion
provisions specified in the applicable Prospectus Supplement.

        Notwithstanding the foregoing, unless (i) if a series of Preferred Stock
has a cumulative dividend, full cumulative dividends on all shares of such
series of Preferred Stock shall have been or contemporaneously are declared and
paid or declared and a sum sufficient for the payment thereof set apart for
payment for all past dividend periods and the then current dividend period, or
(ii) if a series of Preferred Stock does not have a cumulative dividend, full
dividends on all shares of the Preferred Stock of such series have been or
contemporaneously are declared and paid or declared and a sum sufficient for the
payment thereof set apart for payment for the then current dividend period, no
shares of such series of Preferred Stock shall be redeemed unless all
outstanding shares of Preferred Stock of such series are simultaneously
redeemed; provided, however,

                                       21
<PAGE>   23
that the foregoing shall not prevent the purchase or acquisition of Preferred
Stock of such series to preserve the REIT status of the Company or pursuant to a
purchase or exchange offer made on the same terms to holders of all outstanding
shares of Preferred Stock of such series. In addition, unless (i) if such series
of Preferred Stock has a cumulative dividend, full cumulative dividends on all
outstanding shares of such series of Preferred Stock have been or
contemporaneously are declared and paid or declared and a sum sufficient for the
payment thereof set apart for payment for all past dividend periods and the then
current dividend period, or (ii) if such series of Preferred Stock does not have
a cumulative dividend, full dividends on the Preferred Stock of such series have
been or contemporaneously are declared and paid or declared and a sum sufficient
for the payment thereof set apart for payment for the then current dividend
period, the Company shall not purchase or otherwise acquire directly or
indirectly any shares of Preferred Stock of such series (except by conversion
into or exchange for capital shares of the Company ranking junior to the
Preferred Stock of such series as to dividends and upon liquidation); provided,
however, that the foregoing shall not prevent the purchase or acquisition of
shares of Preferred Stock of such series to preserve the REIT status of the
Company or pursuant to a purchase or exchange offer made on the same terms to
holders of all outstanding shares of Preferred Stock of such series.

        If fewer than all of the outstanding shares of Preferred Stock of any
series are to be redeemed, the number of shares to be redeemed will be
determined by the Company and such shares may be redeemed pro rata from the
holders of record of such shares in proportion to the number of such shares held
or for which redemption is requested by such holder (with adjustments to avoid
redemption of fractional shares) or by any other equitable manner determined by
the Company.

        Notice of redemption will be mailed at least thirty (30) days but not
more than sixty (60) days before the redemption date to each holder of record of
Preferred Stock of any series to be redeemed at the address shown on the stock
transfer books of the Company. Each notice shall state: (i) the redemption date;
(ii) the number of shares and series of the Preferred Stock to be redeemed;
(iii) the redemption price; (iv) the place or places where certificates for such
Preferred Stock are to be surrendered for payment of the redemption price; (v)
that dividends on the shares to be redeemed will cease to accrue on such
redemption date; and (vi) the date upon which the holder's conversion rights, if
any, as to such shares shall terminate. If fewer than all the shares of
Preferred Stock of any series are to be redeemed, the notice mailed to each such
holder thereof shall also specify the number of shares of Preferred Stock to be
redeemed from each such holder. If notice of redemption of any Preferred Stock
has been given and if the funds necessary for such redemption have been set
aside by the Company in trust for the benefit of the holders of any Preferred
Stock so called for redemption, then from and after the redemption date
dividends will cease to accrue on such Preferred Stock, and all rights of the
holders of such shares will terminate, except the right to receive the
redemption price.

LIQUIDATION PREFERENCE

        Upon any voluntary or involuntary liquidation, dissolution or winding up
of the affairs of the Company, then, before any distribution or payment shall be
made to the holders of any Common Stock or any other class or series of capital
stock of the Company ranking junior to the Preferred Stock in the distribution
of assets upon any liquidation, dissolution or winding up of the Company, the
holders of each series of Preferred Stock shall be entitled to receive out of
assets of the Company legally available for distribution to stockholders
liquidating distributions in the amount of the liquidation preference per share,
if any, set forth in the applicable Prospectus Supplement, plus an amount equal
to all dividends accrued and unpaid thereon (which shall not include any
accumulation in respect of unpaid noncumulative dividends for prior dividend
periods). After payment of the full amount of the liquidating distributions to
which they are entitled, the holders of Preferred Stock will have no right or
claim to any of the remaining assets of the Company. In the event that, upon any
such voluntary or involuntary liquidation, dissolution or winding up, the
available assets of the Company are insufficient to pay the amount of the
liquidating distributions on all outstanding shares of Preferred Stock and the
corresponding amounts payable on all shares of other classes or series of
capital stock of the Company ranking on a parity with the Preferred Stock in the
distribution of assets, then the holders of the Preferred Stock and all other
such

                                       22
<PAGE>   24
classes or series of capital stock shall share ratably in any such distribution
of assets in proportion to the full liquidating distributions to which they
would otherwise be respectively entitled.

        If liquidating distributions shall have been made in full to all holders
of Preferred Stock, then the remaining assets of the Company shall be
distributed among the holders of any other classes or series of capital stock
ranking junior to the Preferred Stock upon liquidation, dissolution or winding
up, according to their respective rights and preferences and in each case
according to their respective number of shares. For such purposes, the
consolidation or merger of the Company with or into any other corporation, trust
or entity, or the sale, lease or conveyance of all or substantially all of the
property or business of the Company, shall not be deemed to constitute a
liquidation, dissolution or winding up of the Company.

VOTING RIGHTS

        Holders of the Preferred Stock will not have any voting rights, except
as set forth below or as otherwise from time to time required by law or as
indicated in the applicable Prospectus Supplement.

        Unless provided otherwise for any series of Preferred Stock, so long as
any shares of Preferred Stock of a series remain outstanding, the Company will
not, without the affirmative vote or consent of the holders of at least
two-thirds of the shares of such series of Preferred Stock outstanding at the
time, given in person or by proxy, either in writing or at a meeting (such
series voting separately as a class), (i) authorize or create, or increase the
authorized or issued amount of, any class or series of capital stock ranking
prior to such series of Preferred Stock with respect to payment of dividends or
the distribution of assets upon liquidation, dissolution or winding up or
reclassify any authorized capital stock of the Company into such shares, or
create, authorize or issue any obligation or security convertible into or
evidencing the right to purchase any such shares; or (ii) amend, alter or repeal
the provisions of the Company's Articles of Incorporation or the Designating
Amendment for such series of Preferred Stock, whether by merger, consolidation
or otherwise (an "Event"), so as to materially and adversely affect any right,
preference, privilege or voting power of such series of Preferred Stock or the
holders thereof; provided, however, with respect to the occurrence of any of the
Events set forth in (ii) above, so long as the Preferred Stock remains
outstanding with the terms thereof materially unchanged, taking into account
that upon the occurrence of an Event the Company may not be the surviving
entity, the occurrence of any such Event shall not be deemed to materially and
adversely affect such rights, preferences, privileges or voting power of holders
of Preferred Stock, and provided further that (x) any increase in the amount of
the authorized Preferred Stock or the creation or issuance of any other series
of Preferred Stock, or (y) any increase in the amount of authorized shares of
such series or any other series of Preferred Stock, in each case ranking on a
parity with or junior to the Preferred Stock of such series with respect to
payment of dividends or the distribution of assets upon liquidation, dissolution
or winding up, shall not be deemed to materially and adversely affect such
rights, preferences, privileges or voting powers.

        The foregoing voting provisions will not apply if, at or prior to the
time when the act with respect to which such vote would otherwise be required
shall be effected, all outstanding shares of such series of Preferred Stock
shall have been redeemed or called for redemption and sufficient funds shall
have been deposited in trust to effect such redemption.

CONVERSION RIGHTS

        The terms and conditions, if any, upon which any series of Preferred
Stock is convertible into Common Stock will be set forth in the applicable
Prospectus Supplement relating thereto. Such terms will include the number of
shares of Common Stock into which the shares of Preferred Stock are convertible,
the conversion price (or manner of calculation thereof), the conversion period,
provisions as to whether conversion will be at the option of the holders of the
Preferred Stock or the Company, the events requiring an adjustment of the
conversion price and provisions affecting conversion in the event of the
redemption of such series of Preferred Stock.

RESTRICTIONS ON OWNERSHIP

        For the Company to qualify as a REIT under the Internal Revenue Code of
1986, as amended (the "Code"), not more than 50% in value of its outstanding
capital stock may be owned, directly or indirectly, by five or fewer individuals
(as defined in the Code to include certain entities) during the last half of a
taxable year. To assist the Company in meeting this requirement, the Company may
take certain actions to limit the beneficial ownership, directly or indirectly,
by a single person of the Company's outstanding equity securities, including any
Preferred Stock of the Company. Therefore, in addition to limitations already
included in the Company's Articles of Incorporation, the Designating Amendment
for each series of Preferred Stock may contain provisions restricting the
ownership and transfer of the Preferred Stock. The applicable Prospectus
Supplement will specify any additional ownership limitation relating to a series
of Preferred Stock. See "Restrictions on Transfers of Capital Stock."

TRANSFER AGENT

        The transfer agent and registrar for the Preferred Stock will be set
forth in the applicable Prospectus Supplement.


                           DESCRIPTION OF COMMON STOCK

        The description of the Company's Common Stock set forth below does not
purport to be complete and is qualified in its entirety by reference to the
Company's Articles of Incorporation and Bylaws.

GENERAL

        Under the Articles of Incorporation, the Company has authority to issue
40 million shares of Common Stock. Under Maryland law, stockholders generally
are not responsible for the Company's debts or obligations. As of December 2,
1997, the Company had outstanding 25,049,106 shares of Common Stock. The Common
Stock is listed on the NYSE and the PCX under the symbol "BYA."

TERMS

        Subject to the preferential rights of any other shares or series of
capital stock and to the provisions of the Company's Articles of Incorporation
regarding Excess Stock, holders of shares of Common Stock will be entitled to
receive dividends on shares of Common Stock if, as and when authorized and
declared by the Board of Directors of the Company out of assets legally
available therefor and to share ratably in the assets of the Company legally
available for distribution to its stockholders in the event of its liquidation,
dissolution or winding-up after payment of, or adequate provision for, all known
debts and liabilities of the Company.

        Subject to the provisions of the Company's Articles of Incorporation
regarding Excess Stock, each outstanding share of Common Stock entitles the
holder to one vote on all matters submitted to a vote of stockholders, including
the election of Directors and, except as otherwise required by law or except as
provided with respect to any other class or series of capital stock, the holders
of Common Stock will possess the exclusive voting power. There is no cumulative
voting in the election of Directors, which means that, subject to any rights to
elect Directors that are granted to the holders of any class or series of
Preferred Stock, the holders of a majority of the outstanding shares of Common
Stock can elect all of the Directors then standing for election, and the holders
of the remaining shares of Common Stock will not be able to elect any Directors.

        Holders of Common Stock have no conversion, sinking fund or redemption
rights, or preemptive rights to subscribe for any securities of the Company.


                                       24
<PAGE>   26
        The Company intends to furnish its stockholders with annual reports
containing audited consolidated financial statements and an opinion thereon
expressed by an independent public accounting firm and quarterly reports for the
first three quarters of each fiscal year containing unaudited financial
information.

        Subject to the provisions of the Company's Articles of Incorporation
regarding Excess Stock, all shares of Common Stock will have equal dividend,
distribution, liquidation and other rights, and will have no preference,
appraisal or exchange rights.

        Pursuant to the MGCL, a corporation generally cannot dissolve, amend its
Articles of Incorporation, merge, sell all or substantially all of its assets,
engage in a share exchange or engage in similar transactions outside the
ordinary course of business unless approved by the affirmative vote of
stockholders holding at least two-thirds of the shares entitled to vote on the
matter unless a lesser percentage is set forth in the Company's Articles of
Incorporation, which percentage shall not in any event be less than a majority
of all of the shares entitled to vote on such matter. The Company's Articles of
Incorporation do not provide for a lesser percentage in such situations.

RESTRICTIONS ON OWNERSHIP

        For the Company to qualify as a REIT under the Code, not more than 50%
in value of its outstanding capital stock may be owned, directly or indirectly,
by five or fewer individuals (as defined in the Code to include certain
entities) during the last half of a taxable year. To assist the Company in
meeting this requirement, the Company may take certain actions to limit the
beneficial ownership, directly or indirectly, by a single person of the
Company's outstanding equity securities. See "Restrictions on Transfers of
Capital Stock."

TRANSFER AGENT

        The transfer agent and registrar for the Common Stock is American Stock
Transfer & Trust Company of New York, New York.


                   RESTRICTIONS ON TRANSFERS OF CAPITAL STOCK

        For the Company to qualify as a REIT under the Code, among other things,
not more than 50% in value of its outstanding capital stock may be owned,
directly or indirectly, by five or fewer individuals (defined in the Code to
include certain entities) during the last half of a taxable year, and such
capital stock must be beneficially owned by 100 or more persons during at least
335 days of a taxable year of twelve (12) months or during a proportionate part
of a shorter taxable year (in each case, other than the first such year). To
ensure that the Company remains a qualified REIT, the Articles of Incorporation,
subject to certain exceptions, provide that no holder may own, or be deemed to
own by virtue of the attribution provisions of the Code, more than nine percent
(9%) (the "Ownership Limit") of any class or series of the Company's capital
stock. The Board of Directors may waive the Ownership Limit if evidence
satisfactory to the Board of Directors and the Company's tax counsel is
presented that the changes in ownership will not then or in the future
jeopardize the Company's status as a REIT. Any transfer of capital stock or any
security convertible into capital stock that would create a direct or indirect
ownership of capital stock in excess of the Ownership Limit or that would result
in the disqualification of the Company as a REIT, including any transfer that
results in the capital stock being owned by fewer than 100 persons or results in
the Company being "closely held" within the meaning of Section 856(h) of the
Code, shall be null and void, and the intended transferee will acquire no rights
to the capital stock. The Board of Directors may, in its discretion, determine
that it is no longer in the best interests of the Company to attempt to qualify,
or to continue to qualify, as a REIT.


                                       25

        Capital stock owned, or deemed to be owned, or transferred to a
stockholder in excess of the Ownership Limit will automatically be exchanged for
shares of Excess Stock that will be transferred, by operation of law, to the
Company as trustee of a trust for the exclusive benefit of the transferees to
whom such capital stock may be ultimately transferred without violating the
Ownership Limit. While the Excess Stock is held in trust, it will not be
entitled to vote, it will not be considered for purposes of any stockholder vote
or the determination of a quorum for such vote and, except upon liquidation, it
will not be entitled to participate in dividends or other distributions. Any
dividend or distribution paid to a proposed transferee of Excess Stock prior to
the discovery by the Company that capital stock has been transferred in
violation of the provisions of the Company's Articles of Incorporation shall be
repaid to the Company upon demand. The Excess Stock is not treasury stock, but
rather constitutes a separate class of issued and outstanding stock of the
Company. The original transferee-stockholder may, at any time the Excess Stock
is held by the Company in trust, transfer the interest in the trust representing
the Excess Stock to any individual whose ownership of the capital stock
exchanged into such Excess Stock would be permitted under the Ownership Limit,
at a price not in excess of the price paid by the original
transferee-stockholder for the capital stock that was exchanged in Excess Stock.
Immediately upon the transfer to the permitted transferee, the Excess Stock will
automatically be exchanged for capital stock of the class from which it was
converted. If the foregoing transfer restrictions are determined to be void or
invalid by virtue of any legal decision, statute, rule or regulation, then the
intended transferee of any Excess Stock may be deemed, at the option of the
Company, to have acted as an agent on behalf of the Company in acquiring the
Excess Stock and to hold the Excess Stock on behalf of the Company.

        In addition to the foregoing transfer restrictions, the Company will
have the right, for a period of 90 days during the time any Excess Stock is held
by the Company in trust, to purchase all or any portion of the Excess Stock from
the original transferee-stockholder for the lesser of the price paid for the
capital stock by the original transferee-stockholder or the market price (as
determined in the manner set forth in the Articles of Incorporation) of the
capital stock on the date the Company exercises its option to purchase. The
90-day period begins on the date on which the Company receives written notice of
the transfer or other event resulting in the exchange of capital stock for
Excess Stock.

        Each stockholder shall upon demand be required to disclose to the
Company in writing any information with respect to the direct, indirect and
constructive ownership of beneficial interests as the Board of Directors deems
necessary to comply with the provisions of the Code applicable to REITs, to
comply with the requirements of any taxing authority or governmental agency or
to determine any such compliance.

        This ownership limitation may have the effect of precluding acquisition
of control of the Company unless the Board of Directors determines that
maintenance of REIT status is no longer in the best interests of the Company.


                        FEDERAL INCOME TAX CONSIDERATIONS


        The Company believes it has operated, and the Company intends to
continue to operate, in such manner as to qualify as a REIT under the Code, but
no assurance can be given that it will at all times so qualify.

        The provisions of the Code pertaining to REITs are highly technical and
complex. The following is a brief and general summary of certain provisions that
currently govern the federal income tax treatment of the Company and its
stockholders. For the particular provisions that govern the federal income tax
treatment of the Company and its stockholders, reference is made to Sections 856
through 860 of the Code and the regulations promulgated thereunder. The
following summary is qualified in its entirety by such reference.

        Under the Code, if certain requirements are met in a taxable year, a
REIT generally will not be subject to federal income tax with respect to income
that it distributes to its stockholders. If the Company fails to

                                       26
<PAGE>   28
qualify during any taxable year as a REIT, unless certain relief provisions are
available, it will be subject to tax (including any applicable alternative
minimum tax) on its taxable income at regular corporate rates, which could have
a material adverse effect upon its stockholders.

        To qualify as a REIT, the Company must comply with a number of annual
requirements regarding its income, assets and distributions. These requirements
impose a number of restrictions on the Company's operations. For example, the
Company may not lease property if the lease has the effect of giving the Company
a share of the net income of the lessee. The amount of personal property that
may be included under a lease may not exceed a defined, low level, and the
Company may not provide services to its tenants, other than customary services
and (beginning in 1998) de minimis non-customary services. The Company's ability
to acquire non-real estate assets is restricted, and a 100% tax is imposed on
any gain that the Company realizes from sales of property to customers in the
ordinary course of business (other than property acquired by reason of certain
foreclosures), effectively preventing the Company from participating directly in
condominium projects and other projects involving the development of property
for resale. Minimum distribution requirements also generally require the Company
to distribute at least 95% of its taxable income each year (excluding any net
capital gain).

        In any year in which the Company qualifies to be taxed as a REIT,
distributions made to its stockholders out of current or accumulated earnings
and profits will be taxed to stockholders as ordinary income except that
distributions of net capital gains designated by the Company as capital gain
dividends will be taxed as long-term capital gain income to the stockholders. To
the extent that distributions exceed current or accumulated earnings and
profits, they will constitute a return of capital, rather than dividend or
capital gain income, and will reduce the basis for the stockholder's Securities
with respect to which the distribution is paid or, to the extent that they
exceed such basis, will be taxed in the same manner as gain from the sale of
those Securities.

        Investors are urged to consult their own tax advisors with respect to
the appropriateness of an investment in the Securities offered hereby and with
respect to the tax consequences arising under federal law and the laws of any
state, municipality or other taxing jurisdiction, including tax consequences
resulting from such investor's own tax characteristics. In particular, foreign
investors should consult their own tax advisors concerning the tax consequences
of an investment in the Company, including the possibility of United States
income tax withholding on Company distributions.


                              PLAN OF DISTRIBUTION

        The Company may sell Securities to or through one or more underwriters
or dealers for public offering and sale by or through them, directly to one or
more purchasers, through agents or through any combination of these methods of
sale. Direct sale to investors also may be accomplished through subscription
rights distributed to the Company's stockholders on a pro rata basis. In
connection with any distribution of subscription rights to stockholders, if all
of the underlying Securities are not subscribed for, the Company may sell the
unsubscribed Securities directly to third parties or may engage the services of
one or more underwriters, dealers or agents, including standby underwriters, to
sell the unsubscribed Securities to third parties.

        The distribution of the Securities may be effected from time to time in
one or more transactions at a fixed price or prices, which may be changed, at
market prices prevailing at the time of sale, at prices related to such
prevailing market prices, or at negotiated prices (any of which may represent a
discount from the prevailing market prices).

        In connection with the sale of Securities, underwriters or agents may
receive compensation from the Company or from purchasers of Securities, for whom
they may act as agents, in the form of discounts, concessions or commissions.
Underwriters may sell Securities to or through dealers, and such dealers may
receive compensation in the form of discounts, concessions or commissions from
the underwriters and/or

                                       27
<PAGE>   29
commissions from the purchasers for whom they may act as agents. Underwriters,
dealers, and agents that participate in the distribution of Securities may be
deemed to be underwriters under the Securities Act, and any discounts or
commissions they receive from the Company and any profit on the resale of
Securities they realize may be deemed to be underwriting discounts and
commissions under the Securities Act. Any such underwriter or agent will be
identified, and any such compensation received from the Company will be
described, in the applicable Prospectus Supplement.

        Unless otherwise specified in the related Prospectus Supplement, each
class or series of Securities will be a new issue with no established trading
market, other than the Common Stock and the Series C Preferred Stock, which are
listed on the NYSE and the PCX. Any shares of Common Stock sold pursuant to a
Prospectus Supplement will be listed on the NYSE and the PCX, subject to
official notice of issuance. The Company may elect to list any series of Debt
Securities or Preferred Stock on an exchange, but is not obligated to do so. It
is possible that one or more underwriters may make a market in a series of
Securities, but will not be obligated to do so and may discontinue any market
making at any time without notice. Therefore, no assurance can be given as to
the liquidity of, or the trading market for, the Securities.

        Under agreements into which the Company may enter, underwriters, dealers
and agents who participate in the distribution of Securities may be entitled to
indemnification by the Company against certain liabilities, including
liabilities under the Securities Act.

        Underwriters, dealers and agents may engage in transactions with, or
perform services for, or be tenants of, the Company in the ordinary course of
business.

        If so indicated in the applicable Prospectus Supplement, the Company
will authorize dealers acting as the Company's agents to solicit offers by
certain institutions to purchase Securities from the Company at the public
offering price set forth in such Prospectus Supplement pursuant to delayed
delivery contracts ("Contracts") providing for payment and delivery on the date
or dates stated in such Prospectus Supplement. Each Contract will be for an
amount not less than, and the aggregate principal amount of Securities sold
pursuant to Contracts shall be not less nor more than, the respective amounts
stated in the applicable Prospectus Supplement. Institutions with whom
Contracts, when authorized, may be made include commercial and savings banks,
insurance companies, pension funds, investment companies, educational and
charitable institutions, and other institutions, but will in all cases be
subject to the approval of the Company. Contracts will not be subject to any
conditions except (i) the purchase by an institution of the Securities covered
by its Contracts shall not at the time of delivery be prohibited under the laws
of any jurisdiction in the United States to which such institution is subject,
and (ii) if the Securities are being sold to underwriters, the Company shall
have sold to such underwriters the total principal amount of the Securities less
the principal amount thereof covered by Contracts. The underwriters and such
other agents will not have any responsibility in respect of the validity or
performance of such Contracts.

        In order to comply with the securities laws of certain states, if
applicable, the Securities offered hereby will be sold in such jurisdictions
only through registered or licensed brokers or dealers. In addition, in certain
states Securities may not be sold unless they have been registered or qualified
for sale in the applicable state or an exemption from the registration or
qualification requirement is available and is complied with.

        Under applicable rules and regulations under the Exchange Act, under
certain circumstances a person engaged in the distribution of the Securities
offered hereby may not simultaneously engage in market making activities with
respect to the Securities for a specified period prior to the commencement of
such distribution.

                 PART II. INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 14.  OTHER EXPENSES OF ISSUANCE AND DISTRIBUTION.

  The expenses in connection with the issuance and distribution of the
securities being registered will be borne by the Company and are set forth in
the following table (all amounts except the registration fee are estimated):

        Registration fee                                            $  59,000
        Legal fees and expenses                                       350,000
        Blue Sky expenses                                              10,000
        Accounting fees and expenses                                  150,000
        Printing fees and expenses                                    150,000
        Miscellaneous                                                  81,000
                                                                    ---------
                  TOTAL                                              $800,000


ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

        Subject to certain limited exceptions, the Company's Articles of
Incorporation and Bylaws, each as amended, limit the liability of the Company's
Directors and officers to the Company for money damages for any breach of any
duty owed by such Director or officer of the Company to the fullest extent
permitted by Maryland law. The Maryland General Corporation Law ("MGCL")
generally permits the liability of Directors and officers to a corporation or
its stockholders for money damages to be limited, unless it is proved that
(i)(a) the Director or officer actually received an improper personal benefit in
money, property or services, (b) the Director or officer acted in bad faith, or
(c) the Director's or officer's act or omission was the result of active and
deliberate dishonesty, and (ii) the Director's or officer's act or omission was
material to the matter giving rise to the proceeding. However, if the proceeding
was one by or in the right of the Company, indemnification may not be made in
respect of any proceeding in which the Director or officer shall have been
adjudged to be liable to the Company. These provisions do not limit the ability
of the Company or its stockholders to obtain other relief, such as an injunction
or rescission.

        Pursuant to the authority granted in the Company's Articles of
Incorporation and Bylaws, the Company has also entered into indemnification
agreements with certain of its executive officers and members of the Board of
Directors who are not officers of the Company, pursuant to which the Company has
agreed to indemnify them against certain liabilities incurred in connection with
their service as executive officers and/or Directors. These provisions and
contracts could reduce the legal remedies available to the Company and its
stockholders against these individuals.

ITEM 17.  UNDERTAKINGS.

       (a)        The undersigned registrant hereby undertakes:

                           (1) To file, during any period in which offers or
                  sales are being made, a post-effective amendment to this
                  registration statement:

                                    (i) To include any prospectus required by
                           Section 10(a)(3) of the Securities Act;

                                    (ii) To reflect in the prospectus any facts
                           or events arising after the effective date of the
                           registration statement (or the most recent
                           post-effective amendment thereof) which, individually
                           or in the aggregate, represent a fundamental change
                           in the information set forth in the registration
                           statement. Notwithstanding the foregoing, any
                           increase or decrease in volume of securities offered
                           (if the total dollar value of securities offered
                           would not exceed that which was registered) and any
                           deviation from the low or high end of the estimated
                           offering range may be reflected in the form of
                           prospectus filed with the Commission pursuant to Rule
                           424(b) if, in the aggregate, the changes in volume
                           and price represent no more than a 20% change in the
                           maximum aggregate offering price set forth in the
                           "Calculation of Registration Fee" table in the
                           effective registration statement; and

                                    (iii) To include any material information
                           with respect to the plan of distribution not
                           previously disclosed in the registration statement or
                           any material change to such information in the
                           registration statement;

                  provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do
                  not apply if the information required to be included in a
                  post-effective amendment by those paragraphs is contained in
                  periodic reports filed by the undersigned registrant pursuant
                  to Section 13 or Section 15(d) of the Exchange Act that are
                  incorporated by reference in the registration statement;

                           (2) That, for the purpose of determining any
                  liability under the Securities Act, each such post-effective
                  amendment shall be deemed to be a new registration statement
                  relating to the securities offered therein, and the offering
                  of such securities at that time shall be deemed to be the
                  initial bona fide offering thereof; and

                           (3) To remove from registration by means of a
                  post-effective amendment any of the securities being
                  registered which remain unsold at the termination of the
                  offering.

       (b)        The registrant hereby undertakes that, for purposes of
                  determining any liability under the Securities Act, each
                  filing of the registrant's annual report pursuant to Section
                  13(a) or 15(d) of the Exchange Act (and, where applicable,
                  each filing of an employee benefit plan's annual report
                  pursuant to Section 15(d) of the Exchange Act) that is
                  incorporated by reference in the registration statement shall
                  be deemed to be a new registration statement relating to the
                  securities offered therein, and the offering of such
                  securities at that time shall be deemed to be the initial bona
                  fide offering thereof.

<PAGE>   34
       (c)        Insofar as indemnification for liabilities arising under the
                  Securities Act may be permitted to directors, officers and
                  controlling persons of the registrant pursuant to the
                  foregoing provisions, or otherwise, the registrant has been
                  advised that in the opinion of the Commission such
                  indemnification is against public policy as expressed in the
                  Act and is, therefore, unenforceable. In the event that a
                  claim for indemnification against such liabilities (other than

shall be protected in making such calculation or in relying upon any such
request, demand, authorization, direction, notice, consent or waiver, only
Securities which the Trustee knows to be so owned shall be so disregarded.
Securities owned as provided in clause (iv) above which have been pledged in
good faith may be regarded as Outstanding if the pledgee establishes to the
satisfaction of the Trustee the pledgee's right so to act with respect to such
Securities and that the pledgee is not the Company or any other obligor upon the
Securities or any Affiliate of the Company or of such other obligor. In case of
a dispute as to such right, the advice of counsel shall be full protection in
respect of any decision made by the Trustee in accordance with such advice.

         Every certificate or opinion with respect to compliance with a

                                       12
<PAGE>   19
certify or give an opinion with respect to some matters and one or more other

opinion as to such matters in one or several documents.

         Any certificate or opinion of an officer of the Company may be based,
insofar as it relates to legal matters, upon an Opinion of Counsel, or a
certificate or representations by counsel, unless such officer knows, or in the
exercise of reasonable care should know, that the opinion, certificate or
representations with respect to the matters upon which his certificate or

possession of the Company, unless such counsel knows, or in the exercise of
reasonable care should know, that the certificate or opinion or representations

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

         SECTION 104. Acts of Holders. (a) Any request, demand, authorization,
direction, notice, consent, waiver or other action provided by this Indenture to
be given or taken by Holders of the Outstanding Securities of all series or one
or more series, as the case may be, may be embodied in and evidenced by one or
more instruments of substantially similar tenor signed by such Holders in person
or by agents duly appointed in writing. If Securities of a series are issuable
as Bearer Securities, any request, demand, authorization, direction, notice,
consent, waiver or other action provided by this Indenture to be given or taken
by Holders of Securities of such series may, alternatively, be embodied in and
evidenced by the record of Holders of Securities of such series voting in favor
thereof, either in person or by proxies duly appointed in writing, at any
meeting of Holders of Securities of such series duly called and held in
accordance with the provisions of Article Fifteen, or a combination of such
instruments and any such record. Except as herein otherwise expressly provided,
such action shall become effective when such instrument or instruments or record
or both are delivered to the Trustee and, where it is hereby expressly required,
to the Company. Such instrument or instruments and any such record (and the
action embodied therein and evidenced thereby) are herein sometimes referred to
as the "Act" of the Holders signing such instrument or instruments or so voting
at any such meeting. Proof of execution of any such instrument or of a writing
appointing any such agent, or of the holding by any Person of a Security, shall
be sufficient for any purpose of this Indenture and conclusive in favor of the
Trustee and the Company and any agent of the Trustee or the Company, if made in
the manner provided in this Section. The record of any meeting of Holders of
Securities shall be proved in the manner provided in Section 1506.

                                       13
<PAGE>   20
                  (b) The fact and date of the execution by any Person of any
such instrument or writing may be proved by the affidavit of a witness of such
execution or by a certificate of a notary public or other officer authorized by
law to take acknowledgments of deeds, certifying that the individual signing
such instrument or writing acknowledged to him the execution thereof. Where such
execution is by a signer acting in a capacity other than his individual
capacity, such certificate or affidavit shall also constitute sufficient proof
of his authority. The fact and date of the execution of any such instrument or
writing, or the authority of the Person executing the same, may also be proved
in any other reasonable manner which the Trustee deems sufficient.

                  (c) The ownership of Registered Securities shall be proved by
the Security Register. As to any matter relating to beneficial ownership
interests in any Global Security, the appropriate depository's records shall be
dispositive for purposes of this Indenture.

                  (d) The ownership of Bearer Securities may be proved by the
production of such Bearer Securities or by a certificate executed, as
depository, by any trust company, bank, banker or other depository, wherever
situated, if such certificate shall be deemed by the Trustee to be satisfactory,
showing that at the date therein mentioned such Person had on deposit with such
depository, or exhibited to it, the Bearer Securities therein described; or such
facts may be proved by the certificate or affidavit of the Person holding such
Bearer Securities, if such certificate or affidavit is deemed by the Trustee to
be satisfactory. The Trustee and the Company may assume that such ownership of
any Bearer Security continues until (1) another certificate or affidavit bearing
a later date issued in respect of the same Bearer Security is produced, or (2)
such Bearer Security is produced to the Trustee by some other Person, or (3)
such Bearer Security is surrendered in exchange for a Registered Security, or
(4) such Bearer Security is no longer Outstanding. The ownership of Bearer
Securities may also be proved in any other manner which the Trustee deems
sufficient.

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

                                       14
<PAGE>   21
authorization, agreement or consent by the Holders on such record date shall be
deemed effective unless it shall become effective pursuant to the provisions of
this Indenture not later than eleven months after the record date.

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

         SECTION 105. Notices, etc., to Trustee and Company. Any request,
demand, authorization, direction, notice, consent, waiver or Act of Holders or
other document provided or permitted by this Indenture to be made upon, given or
furnished to, or filed with,

                           (1) the Trustee by any Holder or by the Company shall
         be sufficient for every purpose hereunder if made, given, furnished or
         filed in writing to or with the Trustee at
         [__________________________]; or

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

                           (3) either the Trustee or the Company, by the other
         party, shall be sufficient for every purpose hereunder if given by
         facsimile transmission, receipt confirmed by telephone followed by an
         original copy delivered by guaranteed overnight courier; if to the
         Trustee at facsimile number [_________________]; and if to the Company
         at facsimile number (408) 554-9780.

         SECTION 106. Notice to Holders: Waiver. Where this Indenture provides
for notice of any event to Holders of Registered Securities by the Company or
the Trustee, such notice shall be sufficiently given (unless otherwise herein
expressly provided) if in writing and mailed, first-class postage prepaid, to
each such Holder affected by such event, at his address as it appears in the
Security Register, not later than the latest date, if any, and not earlier than
the earliest date, if any, prescribed for the giving of such notice. In any case
where notice to Holders of Registered Securities is given by mail, neither the
failure to mail such notice, nor any defect in any notice so mailed, to any
particular Holder shall affect the sufficiency of such notice with respect to
other Holders of Registered Securities or the sufficiency of any notice to
Holders of Bearer Securities given as provided herein. Any notice mailed to a
Holder in the 

                                       15
<PAGE>   22
manner herein prescribed shall be conclusively deemed to have been
received by such Holder, whether or not such Holder actually receives such
notice.

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

         Except as otherwise expressly provided herein or otherwise specified
with respect to any Securities pursuant to Section 301, where this Indenture
provides for notice to Holders of Bearer Securities of any event, such notice
shall be sufficiently given if published in an Authorized Newspaper in The City
of New York and in such other city or cities as may be specified in such
Securities on a Business Day, such publication to be not later than the latest
date, if any, and not earlier than the earliest date, if any, prescribed for the
giving of such notice. Any such notice shall be deemed to have been given on the
date of such publication or, if published more than once, on the date of the
first such publication.

         If by reason of the suspension of publication of any Authorized
Newspaper or Authorized Newspapers or by reason of any other cause it shall be
impracticable to publish any notice to Holders of Bearer Securities as provided
above, then such notification to Holders of Bearer Securities as shall be given
with the approval of the Trustee shall constitute sufficient notice to such
Holders for every purpose hereunder. Neither the failure to give notice by
publication to any particular Holder of Bearer Securities as provided above, nor
any defect in any notice so published, shall affect the sufficiency of such
notice with respect to other Holders of Bearer Securities or the sufficiency of
any notice to Holders of Registered Securities given as provided herein.

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

         Where this Indenture provides for notice in any manner, such notice may
be waived in writing by the Person entitled to receive such notice, either
before or after the event, and such waiver shall be the equivalent of such
notice. Waivers of notice by Holders shall be filed with the Trustee, but such
filing shall not be a condition precedent to the validity of any action taken in
reliance upon such waiver.

         SECTION 107. Counterparts; Effect of Headings and Table of Contents.
This Indenture may be executed in any number of counterparts, each of which so
executed shall be deemed to be an original, but all such counterparts shall
together constitute but one and the same Indenture. The Article and Section
headings herein and the Table of Contents are for convenience only and shall not
affect the construction hereof.

         SECTION 108. Successors and Assigns. All covenants and agreements in
this Indenture by the Company shall bind its successors and assigns, whether so
expressed or not.

         SECTION 109. Severability Clause. In case any provision in this
Indenture or in any Security or coupon shall be held invalid, illegal or
unenforceable, the validity, legality and enforceability of the remaining
provisions shall not in any way be affected or impaired thereby.

         SECTION 110. Benefits of Indenture. Nothing in this Indenture or in the
Securities or coupons, express or implied, shall give to any Person, other than
the parties hereto, any Security Registrar, any Paying Agent, any Authenticating
Agent and their successors hereunder and the Holders any benefit or any legal or
equitable right, remedy or claim under this Indenture.

         SECTION 111. Governing Law. This Indenture and the Securities and
coupons shall be governed by and construed in accordance with the law of the
State of New York. This Indenture is subject to the provisions of the TIA that
are required to be part of this Indenture and shall, to the extent applicable,
be governed by such provisions.

         SECTION 112. Legal Holidays. In any case where any Interest Payment
Date, Redemption Date, Repayment Date, sinking fund payment date, Stated
Maturity or Maturity of any Security or the last date on which a Holder has the
right to exchange a Security shall not be a Business Day at any Place of
Payment, then (notwithstanding any other provision of this Indenture or any
Security or coupon other than a provision in the Securities of any series which
specifically states that such provision shall apply in lieu hereof), payment of
interest or principal (and premium or Make-Whole Amount, if any) or exchange of
such security need not be made at such Place of Payment on such date, but
(except as otherwise provided in the supplemental indenture with respect to such
Security) may be made on the next succeeding Business Day at such Place of
Payment with the same force and effect as if made on the Interest Payment Date,
Redemption Date, Repayment Date or sinking fund payment date, or at the Stated
Maturity or Maturity, or on such last day for exchange, provided that no
interest shall accrue on the amount so payable for the period from and after
such Interest Payment Date, Redemption Date, Repayment Date, sinking fund
payment date, Stated Maturity or Maturity, as the case may be.

         SECTION 113. Immunity of Stockholders, Directors, Officers and Agents
of the Company. No recourse under or upon any obligation, covenant or agreement
contained in this Indenture, or in any Security, or because of any indebtedness
evidenced thereby, shall be had against any past, present or future stockholder,
employee, officer or director, as such, of the Company or of any successor,
either directly or through the Company or any successor, under any rule of law,
statute or constitutional provision or by the enforcement of any assessment or
by any legal or equitable proceeding or otherwise, all such liability being
expressly waived and released by the acceptance of the Securities by the Holders
and as part of the consideration for the issue of the Securities.

         SECTION 114. Conflict with Trust Indenture Act. If any provision hereof
limits, qualifies or conflicts with another provision hereof which is required
or deemed to be included in this Indenture by any of the provisions of the Trust
Indenture Act, such required provision shall control. If any provision of this
Indenture modifies or excludes any provision of the Trust Indenture Act that may
be so modified or excluded, the latter provision shall be deemed to apply to
this Indenture as so modified or to be excluded, as the case may be.

         SECTION 203. Securities Issuable in Global Form. If Securities of or
within a series are issuable in the form of one or more Global Securities, then,
notwithstanding clause (8) of Section 301 and the provisions of Section 302, any
such Global Security or Securities may provide that it or they shall represent
the aggregate amount of all Outstanding Securities of such series (or such
lesser amount as is permitted by the terms thereof) from time to time endorsed
thereon and may also provide that the aggregate amount of Outstanding Securities
of such series represented thereby may from time to time be increased or
decreased to reflect exchanges. Any endorsement of any Global Security to
reflect the amount, or any increase or decrease in the amount, or changes in the
rights of Holders thereof, of Outstanding Securities represented thereby shall
be made by the Trustee in such manner or by such Person or Persons as shall be
specified therein or in the Company Order to be delivered to the Trustee
pursuant to Section 303 or 304. Subject to the provisions of Section 303 and, if
applicable, Section 304, the Trustee shall deliver and redeliver any Global
Security in permanent global form in the manner and upon instructions given by
the Person or Persons specified therein or in the applicable Company Order. If a
Company Order pursuant to Section 303 or 304 has been, or simultaneously is,
delivered, any instructions by the Company with respect to endorsement or
delivery or redelivery of a Global Security shall be in writing but need not
comply with Section 102 and need not be accompanied by an Opinion of Counsel.

         The provisions of the last sentence of Section 303 shall apply to any
Security represented by a Global Security if such Security was never issued and
sold by the Company and the Company delivers to the Trustee the Global Security
together with written instructions (which need not comply with Section 102 and
need not be accompanied by an Opinion of Counsel) with regard to the reduction
in the principal amount of Securities represented thereby, together with the
written statement contemplated by the last sentence of Section 303.

         Notwithstanding the provisions of Section 307, unless otherwise
specified as contemplated by Section 301, payment of principal of and any
premium or Make-Whole Amount, if any, and interest on any Global Security in
permanent global form shall be made to the registered Holder thereof.

         Notwithstanding the provisions of Section 308 and except as provided in
the preceding paragraph, the Company, the Trustee and any agent of the Company
and the Trustee shall treat

                                       19
<PAGE>   26

as the Holder of such principal amount of Outstanding Securities represented by
a permanent Global Security (i) in the case of a permanent Global Security in
registered form, the Holder of such permanent Global Security in registered
form, or (ii) in the case of a permanent Global Security in bearer form,
Euroclear or CEDEL.

         Any Global Security authenticated and delivered hereunder shall bear a
legend in substantially the following form:

                  "This Security is a Global Security within the meaning set
                  forth in the Indenture hereinafter referred to and is
                  registered in the name of a Depository or a nominee of a
                  Depository. This Security is exchangeable for Securities
                  registered in the name of a person other than the Depository
                  or its nominee only in the limited circumstances described in
                  the Indenture, and may not be transferred except as a whole by
                  the Depository to a nominee of the Depository or by a nominee
                  of the Depository to the Depository or another nominee of the
                  Depository or by the Depository or its nominee to a successor
                  Depository or its nominee."

                           (10) If other than Dollars, the currency or

<PAGE>   28
         formula or other method (which index, formula or method may, but need
         not be, based on the yield on or trading price of other securities,
         including United States Treasury securities or on a currency,
         currencies, currency unit or units, or composite currency or

         additions to the Events of Default or covenants of the Company with
         respect to Securities of the series, whether or not such Events of
         Default or covenants are consistent with the Events of Default or

                           (16) Whether Securities of the series are to be
         issuable as Registered Securities, Bearer Securities (with or without

         the series and vice versa (if permitted by applicable laws and
         regulations), whether any Securities of the series are to be issuable

<PAGE>   29
                           (17) The date as of which any Bearer Securities of
         the series and any temporary Global Security representing outstanding
         Securities of the series shall be dated if other than the date of
         original issuance of the first Security of the series to be issued;

                           (18) The Person to whom any interest on any
         Registered Security of the series shall be payable, if other than the
         Person in whose name that Security (or one or more Predecessor
         Securities) is registered at the close of business on the Regular
         Record Date for such interest, the manner in which, or the Person to
         whom, any interest on any Bearer Security of the series shall be
         payable, if otherwise than upon presentation and surrender of the
         coupons appertaining thereto as they severally mature, and the extent
         to which, or the manner in which, any interest payable on a temporary
         Global Security on an Interest Payment Date will be paid if other than
         in the manner provided herein;

                           (19) The applicability, if any, of the defeasance and
         covenant defeasance provisions of Article Fourteen hereof to the
         Securities of the series;

                           (20) If the Securities of such series are to be
         issuable in definitive form (whether upon original issue or upon
         exchange of a temporary Security of such series) only upon receipt of
         certain certificates or other documents or satisfaction of other
         conditions, then the form and/or terms of such certificates, documents
         or conditions; and

                           (21) Any other terms of the series (which terms shall
         not be inconsistent with the provisions of this Indenture).

         All Securities of any one series and the coupons appertaining to any
Bearer Securities of such series shall be substantially identical except, in the
case of Registered Securities, as to denomination and except as may otherwise be
provided in or pursuant to such Board Resolution (subject to Section 303) and
set forth in such Officers' Certificate or in any such indenture supplemental
hereto. All Securities of any one series need not be issued at the same time
and, unless otherwise provided, a series may be reopened, without the consent of
the Holders, for issuances of additional Securities of such series.

         If any of the terms of the Securities of any series are established by
action taken pursuant to one or more Board Resolutions, a copy of an appropriate
record of such action(s) shall be certified by the Secretary or an Assistant
Secretary of the Company and delivered to the Trustee at or prior to the
delivery of the Officers' Certificate setting forth the terms of the Securities
of such series.

         SECTION 302. Denominations. The Securities of each series shall be
issuable in such denominations as shall be specified as contemplated by Section
301. With respect to Securities

                                       23
<PAGE>   30
of any series denominated in Dollars, in the absence of any such provisions with
respect to the Securities of any series, the Securities of such series, other
than Global Securities (which may be of any denomination), shall be issuable in
denominations of $1,000 and any integral multiple thereof.

         SECTION 303. Execution, Authentication, Delivery and Dating. The
Securities and any coupons appertaining thereto shall be executed on behalf of
the Company by its Chairman of the Board, its President or one of its Vice
Presidents, under its corporate seal reproduced thereon, and attested by its
Secretary or one of its Assistant Secretaries. The signature of any of these
officers on the Securities and coupons may be manual or facsimile signatures of
the present or any future such authorized officer and may be imprinted or
otherwise reproduced on the Securities.

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

         At any time and from time to time after the execution and delivery of
this Indenture, the Company may deliver Securities of any series, together with
any coupon appertaining thereto, executed by the Company to the Trustee for
authentication, together with a Company Order for the authentication and
delivery of such Securities, and the Trustee in accordance with the Company
Order shall authenticate and deliver such Securities; provided, however, that,
in connection with its original issuance, no Bearer Security shall be mailed or
otherwise delivered to any location in the United States; and provided further
that, unless otherwise specified with respect to any series of Securities
pursuant to Section 301, a Bearer Security may be delivered in connection with
its original issuance only if the Person entitled to receive such Bearer
Security shall have furnished a certificate to Euroclear or CEDEL, as the case
may be, in the form set forth in Exhibit B-1 to this Indenture or such other
certificate as may be specified with respect to any series of Securities
pursuant to Section 301, dated no earlier than 15 days prior to the earlier of
the date on which such Bearer Security is delivered and the date on which any
temporary Security first becomes exchangeable for such Bearer Security in
accordance with the terms of such temporary Security and this Indenture. If any
Security shall be represented by a permanent global Bearer Security, then, for
purposes of this Section and Section 304, the notation of a beneficial owner's
interest therein upon original issuance of such Security or upon exchange of a
portion of a temporary Global Security shall be deemed to be delivery in
connection with its original issuance of such beneficial owner's interest in
such permanent Global Security. Except as permitted by Section 306, the Trustee
shall not authenticate and deliver any Bearer Security unless all appurtenant
coupons for interest then matured have been detached and canceled.

                                       24
<PAGE>   31
         If all the Securities of any series are not to be issued at one time
and if the Board Resolution or supplemental indenture establishing such series
shall so permit, such Company Order may set forth procedures acceptable to the
Trustee for the issuance of such Securities and determining the terms of
particular Securities of such series, such as interest rate or formula, maturity
date, date of issuance and date from which interest shall accrue. In
authenticating such Securities, and accepting the additional responsibilities
under this Indenture in relation to such Securities, the Trustee shall be
entitled to receive, and (subject to TIA Section 315(a) through 315(d)) shall be
fully protected in relying upon,

                  (i) an Opinion of Counsel stating that

                           (a) the form or forms of such Securities and any
                  coupons have been established in conformity with the
                  provisions of this Indenture;

                           (b) the terms of such Securities and any coupons have
                  been established in conformity with the provisions of this
                  Indenture; and

                           (c) such Securities, together with any coupons
                  appertaining thereto, when completed by appropriate insertions
                  and executed and delivered by the Company to the Trustee for
                  authentication in accordance with this Indenture,
                  authenticated and delivered by the Trustee in accordance with
                  this Indenture and issued by the Company in the manner and
                  subject to any conditions specified in such Opinion of
                  Counsel, will constitute legal, valid and legally binding
                  obligations of the Company, enforceable in accordance with
                  their terms, subject to applicable bankruptcy, insolvency,
                  fraudulent transfer, reorganization and other similar laws of
                  general applicability relating to or affecting the enforcement
                  of creditors' rights generally and to general equitable
                  principles; and

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

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

         Notwithstanding the provisions of Section 301 and of the preceding
paragraph, if all the Securities of any series are not to be issued at one time,
it shall not be necessary to deliver an Officers' Certificate otherwise required
pursuant to Section 301 or a Company Order, or an Opinion of Counsel or an
Officers' Certificate otherwise required pursuant to the preceding 

                                       25
<PAGE>   32
paragraph at the time of issuance of each Security of such series, but such
order, opinion and certificates, with appropriate modifications to cover such
future issuances, shall be delivered at or before the time of issuance of the
first Security of such series.

         Each Registered Security shall be dated the date of its authentication
and each Bearer Security shall be dated as of the date specified as contemplated
by Section 301.

         No Security or coupon shall be entitled to any benefit under this
Indenture or be valid or obligatory for any purpose unless there appears on such
Security or Security to which such coupon appertains a certificate of
authentication substantially in the form provided for herein duly executed by
the Trustee by manual signature of an authorized signatory, and such certificate
upon any Security shall be conclusive evidence, and the only evidence, that such
Security has been duly authenticated and delivered hereunder and is entitled to
the benefits of this Indenture. Notwithstanding the foregoing, if any Security
(including a Global Security) shall have been authenticated and delivered
hereunder but never issued and sold by the Company, and the Company shall
deliver such Security to the Trustee for cancellation as provided in Section 309
together with a written statement (which need not comply with Section 102 and
need not be accompanied by an Opinion of Counsel) stating that such Security has
never been issued and sold by the Company, for all purposes of this Indenture
such Security shall be deemed never to have been authenticated and delivered
hereunder and shall never be entitled to the benefits of this Indenture.

         SECTION 304.  Temporary Securities.

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

         Except in the case of temporary Global Securities (which shall be
exchanged as otherwise provided herein or as otherwise provided in or pursuant
to a Board Resolution), if temporary Securities of any series are issued, the
Company will cause definitive Securities of that series to be prepared without
unreasonable delay. After the preparation of definitive Securities of such
series, the temporary Securities of such series shall be exchangeable for
definitive Securities of such series upon surrender of the temporary Securities
of such series at the office or agency of the Company in a Place of Payment for
that series, without charge to the Holder. Upon surrender for cancellation of
any one or more temporary Securities of any series (accompanied by any
non-matured coupons appertaining thereto), the Company shall 

                                       26
<PAGE>   33
execute and the Trustee shall authenticate and deliver in exchange therefor a
like principal amount of definitive Securities of the same series of authorized
denominations; provided, however, that no definitive Bearer Security shall be
delivered in exchange for a temporary Registered Security; and provided further
that a definitive Bearer Security shall be delivered in exchange for a temporary
Bearer Security only in compliance with the conditions set forth in Section 303.
Until so exchanged, the temporary Securities of any series shall in all respects
be entitled to the same benefits under this Indenture as definitive Securities
of such series.

         (b) Unless otherwise provided in or pursuant to a Board Resolution, the
following provisions of this Section 304(b) shall govern the exchange of
temporary Securities other than through the facilities of The Depository Trust
Company. If any such temporary Security is issued in global form, then such
temporary Global Security shall, unless otherwise provided therein, be delivered
to the London office of a depository or common depository (the "Common
Depository"), for the benefit of Euroclear and CEDEL, for credit to the
respective accounts of the beneficial owners of such Securities (or to such
other accounts as they may direct).

         Without unnecessary delay but in any event not later than the date
specified in, or determined pursuant to the terms of, any such temporary Global
Security (the "Exchange Date"), the Company shall deliver to the Trustee
definitive Securities, in aggregate principal amount equal to the principal
amount of such temporary Global Security, executed by the Company. On or after
the Exchange Date, such temporary Global Security shall be surrendered by the
Common Depository to the Trustee, as the Company's agent for such purpose, to be
exchanged, in whole or from time to time in part, for definitive Securities
without charge, and the Trustee shall authenticate and deliver, in exchange for
each portion of such temporary Global Security, an equal aggregate principal
amount of definitive Securities of the same series of authorized denominations
and of like tenor as the portion of such temporary Global Security to be
exchanged. The definitive Securities to be delivered in exchange for any such
temporary Global Security shall be in bearer form, registered form, permanent
global bearer form or permanent global registered form, or any combination
thereof, as specified as contemplated by Section 301, and, if any combination
thereof is so specified, as requested by the beneficial owner thereof; provided,
however, that, unless otherwise specified in such temporary Global Security,
upon such presentation by the Common Depository, such temporary Global Security
is accompanied by a certificate dated the Exchange Date or a subsequent date and
signed by Euroclear as to the portion of such temporary Global Security held for
its account then to be exchanged and a certificate dated the Exchange Date or a
subsequent date and signed by CEDEL as to the portion of such temporary Global
Security held for its account then to be exchanged, each in the form set forth
in Exhibit A-2 to this Indenture or in such other form as may be established
pursuant to Section 301; and provided further that definitive Bearer Securities
shall be delivered in exchange for a portion of a temporary Global Security only
in compliance with the requirements of Section 303.

         Unless otherwise specified in such temporary Global Security, the
interest of a beneficial owner of Securities of a series in a temporary Global
Security shall be exchanged for definitive Securities of the same series and of
like tenor following the Exchange Date when the account holder instructs
Euroclear or CEDEL, as the case may be, to request such exchange on his behalf
and delivers to Euroclear or CEDEL, as the case may be, a certificate in the
form set forth in Exhibit B-1 to this Indenture (or in such other form as may be
established pursuant to Section 301), dated no earlier than 15 days prior to the
Exchange Date, copies of which certificate shall be available from the offices
of Euroclear and CEDEL, the Trustee, any Authenticating Agent appointed for such
series of Securities and each Paying Agent. Unless otherwise specified in such
temporary Global Security, any such exchange shall be made free of charge to the
beneficial owners of such temporary Global Security, except that a Person
receiving definitive Securities must bear the cost of insurance, postage,
transportation and the like unless such Person takes delivery of such definitive
Securities in person at the offices of Euroclear or CEDEL. Definitive Securities
in bearer form to be delivered in exchange for any portion of a temporary Global
Security shall be delivered only outside the United States.

         Until exchanged in full as hereinabove provided, the temporary
Securities of any series shall in all respects be entitled to the same benefits
under this Indenture as definitive Securities of the same series and of like
tenor authenticated and delivered hereunder, except that, unless otherwise
specified as contemplated by Section 301, interest payable on a temporary Global
Security on an Interest Payment Date for Securities of such series occurring
prior to the applicable Exchange Date shall be payable to Euroclear and CEDEL on
such Interest Payment Date upon delivery by Euroclear and CEDEL to the Trustee
of a certificate or certificates in the form set forth in Exhibit B-2 to this
Indenture (or in such other forms as may be established pursuant to Section
301), for credit without further interest on or after such Interest Payment Date
to the respective accounts of Persons who are the beneficial owners of such
temporary Global Security on such Interest Payment Date and who have each
delivered to Euroclear or CEDEL, as the case may be, a certificate dated no
earlier than 15 days prior to the Interest Payment Date occurring prior to such
Exchange Date in the form set forth as Exhibit B-1 to this Indenture (or in such
other forms as may be established pursuant to Section 301). Notwithstanding
anything to the contrary herein contained, the certifications made pursuant to
this paragraph shall satisfy the certification requirements of the preceding two
paragraphs of this Section 304(b) and of the third paragraph of Section 303 of
this Indenture and the interests of the Persons who are the beneficial owners of
the temporary Global Security with respect to which such certification was made
will be exchanged for definitive Securities of the same series and of like tenor
on the Exchange Date or the date of certification if such date occurs after the
Exchange Date, without further act or deed by such beneficial owners. Except as
otherwise provided in this paragraph, no payments of principal or interest owing
with respect to a beneficial interest in a temporary Global Security will be
made unless and until such interest in such temporary Global Security shall have
been exchanged for an interest in a definitive Security. Any interest so
received by Euroclear and CEDEL and not paid as herein provided shall be
returned to the Trustee prior to the expiration of two years after such Interest
Payment Date in order to be repaid to the Company.

         SECTION 305. Registration, Registration of Transfer and Exchange. The
Company shall cause to be kept at the Corporate Trust Office of the Trustee or
in any office or agency of the Company in a Place of Payment a register for each
series of Securities (the registers maintained in such office or in any such
office or agency of the Company in a Place of Payment being herein sometimes
referred to collectively as the "Security Register") in which, subject to such
reasonable regulations as it may prescribe, the Company shall provide for the
registration of Registered Securities and of transfers of Registered Securities.
The Security Register shall be in written form or any other form capable of
being converted into written form within a reasonable time. The Trustee, at its
Corporate Trust Office, is hereby initially appointed "Security Registrar" for
the purpose of registering Registered Securities and transfers of Registered
Securities on such Security Register as herein provided. In the event that the
Trustee shall cease to be Security Registrar, it shall have the right to examine
the Security Register at all reasonable times.

         Subject to the provisions of this Section 305, upon surrender for
registration of transfer of any Registered Security of any series at any office
or agency of the Company in a Place of Payment for that series, the Company
shall execute, and the Trustee shall authenticate and deliver, in the name of
the designated transferee or transferees, one or more new Registered Securities
of the same series, of any authorized denominations and of a like aggregate
principal amount, bearing a number not contemporaneously outstanding, and
containing identical terms and provisions.

         Subject to the provisions of this Section 305, at the option of the
Holder, Registered Securities of any series may be exchanged for other
Registered Securities of the same series, of any authorized denomination or
denominations and of a like aggregate principal amount, containing identical
terms and provisions, upon surrender of the Registered Securities to be
exchanged at any such office or agency. Whenever any such Registered Securities
are so surrendered for exchange, the Company shall execute, and the Trustee
shall authenticate and deliver, the Registered Securities which the Holder
making the exchange is entitled to receive. Unless otherwise specified with
respect to any series of Securities as contemplated by Section 301, Bearer
Securities may not be issued in exchange for Registered Securities.

         If (but only if) permitted by the applicable Board Resolution and
(subject to Section 303) set forth in the applicable Officers' Certificate, or
in any indenture supplemental hereto, delivered as contemplated by Section 301,
at the option of the Holder, Bearer Securities of any series may be exchanged
for Registered Securities of the same series of any authorized denominations and
of a like aggregate principal amount and tenor, upon surrender of the Bearer
Securities to be exchanged at any such office or agency, with all unmatured
coupons and all matured coupons in default thereto appertaining. If the Holder
of a Bearer Security is unable to produce any such unmatured coupon or coupons
or matured coupon or coupons in default, any such permitted exchange may be
effected if the Bearer Securities are accompanied by payment in funds acceptable
to the Company in an amount equal to the face amount of such missing coupon or
coupons, or the surrender of such missing coupon or 

                                       29
<PAGE>   36
coupons may be waived by the Company and the Trustee if there is furnished to
them such security or indemnity as they may require to save each of them and any
Paying Agent harmless. If thereafter the Holder of such Security shall surrender
to any Paying Agent any such missing coupon in respect of which such a payment
shall have been made, such Holder shall be entitled to receive the amount of
such payment; provided, however, that, except as otherwise provided in Section
1002, interest represented by coupons shall be payable only upon presentation
and surrender of those coupons at an office or agency located outside the United
States. Notwithstanding the foregoing, in case a Bearer Security of any series
is surrendered at any such office or agency in a permitted exchange for a
Registered Security of the same series and like tenor after the close of
business at such office or agency on (i) any Regular Record Date and before the
opening of business at such office or agency on the relevant Interest Payment
Date, or (ii) any Special Record Date and before the opening of business at such
office or agency on the related proposed date for payment of Defaulted Interest,
such Bearer Security shall be surrendered without the coupon relating to such
Interest Payment Date or proposed date for payment, as the case may be, and
interest or Defaulted Interest, as the case may be, will not be payable on such
Interest Payment Date or proposed date for payment, as the case may be, in
respect of the Registered Security issued in exchange for such Bearer Security,
but will be payable only to the Holder of such coupon when due in accordance
with the provisions of this Indenture. Whenever any Securities are so
surrendered for exchange, the Company shall execute, and the Trustee shall
authenticate and deliver, the Securities which the Holder making the exchange is
entitled to receive.

         Notwithstanding the foregoing, except as otherwise specified as
contemplated by Section 301, any permanent Global Security shall be exchangeable
only as provided in this paragraph. If the depository for any permanent Global
Security is The Depository Trust Company ("DTC"), then, unless the terms of such
Global Security expressly permit such Global Security to be exchanged in whole
or in part for definitive Securities, a Global Security may be transferred, in
whole but not in part, only to a nominee of DTC, or by a nominee of DTC to DTC,
or to a successor to DTC for such Global Security selected or approved by the
Company or to a nominee of such successor to DTC. If at any time DTC notifies
the Company that it is unwilling or unable to continue as depository for the
applicable Global Security or Securities or if at any time DTC ceases to be a
clearing agency registered under the Securities Exchange Act of 1934 if so
required by applicable law or regulation, the Company shall appoint a successor
depository with respect to such Global Security or Securities. If (x) a
successor depository for such Global Security or Securities is not appointed by
the Company within 90 days after the Company receives such notice or becomes
aware of such unwillingness, inability or ineligibility, (y) an Event of Default
has occurred and is continuing and the beneficial owners representing a majority
in principal amount of the applicable series of Securities represented by such
Global Security or Securities advise DTC to cease acting as depository for such
Global Security or Securities or (z) the Company, in its sole discretion,
determines at any time that all Outstanding Securities (but not less than all)
of any series issued or issuable in the form of one or more Global Securities
shall no longer be represented by such Global Security or Securities, then the
Company shall execute, and the Trustee shall

                                       30
<PAGE>   37
authenticate and deliver definitive Securities of like series, rank, tenor and
terms in definitive form in an aggregate principal amount equal to the principal
amount of such Global Security or Securities. If any beneficial owner of an
interest in a permanent global Security is otherwise entitled to exchange such
interest for Securities of such series and of like tenor and principal amount of
another authorized form and denomination, as specified as contemplated by
Section 301 and provided that any applicable notice provided in the permanent
Global Security shall have been given, then without unnecessary delay but in any
event not later than the earliest date on which such interest may be so
exchanged, the Company shall execute, and the Trustee shall authenticate and
deliver definitive Securities in aggregate principal amount equal to the
principal amount of such beneficial owner's interest in such permanent Global
Security. On or after the earliest date on which such interests may be so
exchanged, such permanent Global Security shall be surrendered for exchange by
DTC or such other depository as shall be specified in the Company Order with
respect thereto to the Trustee, as the Company's agent for such purpose;
provided, however, that no such exchanges may occur during a period beginning at
the opening of business 15 days before any selection of Securities to be
redeemed and ending on the relevant Redemption Date if the Security for which
exchange is requested may be among those selected for redemption; and provided
further that no Bearer Security delivered in exchange for a portion of a
permanent Global Security shall be mailed or otherwise delivered to any location
in the United States. If a Registered Security is issued in exchange for any
portion of a permanent Global Security after the close of business at the office
or agency where such exchange occurs on (i) any Regular Record Date and before
the opening of business at such office or agency on the relevant Interest
Payment Date, or (ii) any Special Record Date and the opening of business at
such office or agency on the related proposed date for payment of Defaulted
Interest, interest or Defaulted Interest, as the case may be, will not be
payable on such Interest Payment Date or proposed date for payment, as the case
may be, in respect of such Registered Security, but will be payable on such
Interest Payment Date or proposed date for payment, as the case may be, only to
the Person to whom interest in respect of such portion of such permanent Global
Security is payable in accordance with the provisions of this Indenture.

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

         Every Registered Security presented or surrendered for registration of
transfer or for exchange or redemption shall (if so required by the Company or
the Security Registrar) be duly endorsed, or be accompanied by a written
instrument of transfer in form satisfactory to the Company and the Security
Registrar, duly executed by the Holder thereof or his attorney duly authorized
in writing.

         No service charge shall be made for any registration of transfer or
exchange of Securities, but the Company may require payment of a sum sufficient
to cover any tax or other 

                                       31
<PAGE>   38
governmental charge that may be imposed in connection with any registration of
transfer or exchange of Securities, other than exchanges pursuant to Section
304, 906, 1107 or 1305 not involving any transfer.

         The Company or the Trustee, as applicable, shall not be required (i) to
issue, register the transfer of or exchange any Security if such Security may be
among those selected for redemption during a period beginning at the opening of
business 15 days before selection of the Securities to be redeemed under Section
1103 and ending at the close of business on (A) if such Securities are issuable
only as Registered Securities, the day of the mailing of the relevant notice of
redemption and (B) if such Securities are issuable as Bearer Securities, the day
of the first publication of the relevant notice of redemption or, if such
Securities are also issuable as Registered Securities and there is no
publication, the mailing of the relevant notice of redemption, or (ii) to
register the transfer of or exchange any Registered Security so selected for
redemption in whole or in part, except, in the case of any Registered Security
to be redeemed in part, the portion thereof not to be redeemed, or (iii) to
exchange any Bearer Security so selected for redemption except that such a
Bearer Security may be exchanged for a Registered Security of that series and
like tenor, provided that such Registered Security shall be simultaneously
surrendered for redemption, or (iv) to issue, register the transfer of or
exchange any Security which has been surrendered for repayment at the option of
the Holder, except the portion, if any, of such Security not to be so repaid.

         SECTION 306. Mutilated, Destroyed, Lost and Stolen Securities. If any
mutilated Security or a Security with a mutilated coupon appertaining to it is
surrendered to the Trustee or the Company, together with, in proper cases, such
security or indemnity as may be required by the Company or the Trustee to save
each of them or any agent of either of them harmless, the Company shall execute
and the Trustee shall authenticate and deliver in exchange therefor a new
Security of the same series and principal amount, containing identical terms and
provisions and bearing a number not contemporaneously outstanding, with coupons
corresponding to the coupons, if any, appertaining to the surrendered Security.

         If there shall be delivered to the Company and to the Trustee (i)
evidence to their satisfaction of the destruction, loss or theft of any Security
or coupon, and (ii) such security or indemnity as may be required by them to
save each of them and any agent of either of them harmless, then, in the absence
of notice to the Company or the Trustee that such Security or coupon has been
acquired by a bona fide purchaser, the Company shall execute and upon its
request the Trustee shall authenticate and deliver, in lieu of any such
destroyed, lost or stolen Security or in exchange for the Security to which a
destroyed, lost or stolen coupon appertains (with all appurtenant coupons not
destroyed, lost or stolen), a new Security of the same series and principal
amount, containing identical terms and provisions and bearing a number not
contemporaneously outstanding, with coupons corresponding to the coupons, if
any, appertaining to such destroyed, lost or stolen Security or to the Security
to which such destroyed, lost or stolen coupon appertains.

                                       32
<PAGE>   39
         Notwithstanding the provisions of the previous two paragraphs, in case
any such mutilated, destroyed, lost or stolen Security or coupon has become or
is about to become due and payable, the Company in its discretion may, instead
of issuing a new Security, with coupons corresponding to the coupons, if any,
appertaining to such destroyed, lost or stolen Security or to the Security to
which such destroyed, lost or stolen coupon appertains, pay such Security or
coupon; provided, however, that payment of principal of (and premium or
Make-Whole Amount, if any), and any interest on, Bearer Securities shall, except
as otherwise provided in Section 1002, be payable only at an office or agency
located outside the United States and, unless otherwise specified as
contemplated by Section 301, any interest on Bearer Securities shall be payable
only upon presentation and surrender of the coupons appertaining thereto.

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

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

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

         SECTION 307. Payment of Interest; Interest Rights Preserved. Except as
otherwise specified with respect to a series of Securities in accordance with
the provisions of Section 301, interest on any Registered Security that is
payable, and is punctually paid or duly provided for, on any Interest Payment
Date shall be paid to the Person in whose name that Security (or one or more
Predecessor Securities) is registered at the close of business on the Regular
Record Date for such interest at the office or agency of the Company maintained
for such purpose pursuant to Section 1002; provided, however, that each
installment of interest on any Registered Security may at the Company's option
be paid by (i) mailing a check for such interest, payable to or upon the written
order of the Person entitled thereto pursuant to Section 308, to the address of
such Person as it appears on the Security Register or (ii) transfer to an
account maintained by the payee located inside the United States.

                                       33
<PAGE>   40
         Unless otherwise provided as contemplated by Section 301 with respect
to the Securities of any series, payment of interest may be made, in the case of
a Bearer Security, by transfer to an account maintained by the payee with a bank
located outside the United States.

         Unless otherwise provided as contemplated by Section 301, every
permanent global Security will provide that interest, if any, payable on any
Interest Payment Date will be paid to DTC, Euroclear and/or CEDEL, as the case
may be, with respect to that portion of such permanent global Security held for
its account by Cede & Co. or the Common Depository, as the case may be, for the
purpose of permitting such party to credit the interest received by it in
respect of such permanent global Security to the accounts of the beneficial
owners thereof.

         In case a Bearer Security of any series is surrendered in exchange for
a Registered Security of such series after the close of business (at an office
or agency in a Place of Payment for such series) on any Regular Record Date and
before the opening of business (at such office or agency) on the next succeeding
Interest Payment Date, such Bearer Security shall be surrendered without the
coupon relating to such Interest Payment Date and interest will not be payable
on such Interest Payment Date in respect of the Registered Security issued in
exchange for such Bearer Security, but will be payable only to the Holder of
such coupon when due in accordance with the provisions of this Indenture.

         Except as otherwise specified with respect to a series of Securities in
accordance with the provisions of Section 301, any interest on any Registered
Security of any series that is payable, but is not punctually paid or duly
provided for, on any Interest Payment Date (herein called "Defaulted Interest")
shall forthwith cease to be payable to the registered Holder thereof on the
relevant Regular Record Date by virtue of having been such Holder, and such
Defaulted Interest may be paid by the Company, at its election in each case, as
provided in clause (1) or (2) below:

                           (1) The Company may elect to make payment of any
         Defaulted Interest to the Persons in whose names the Registered
         Securities of such series (or their respective Predecessor Securities)
         are registered at the close of business on a Special Record Date for
         the payment of such Defaulted Interest, which shall be fixed in the
         following manner. The Company shall notify the Trustee in writing of
         the amount of Defaulted Interest proposed to be paid on each Registered
         Security of such series and the date of the proposed payment (which
         shall not be less than 20 days after such notice is received by the
         Trustee), and at the same time the Company shall deposit with the
         Trustee an amount of money in the currency or currencies, currency unit
         or units or composite currency or currencies in which the Securities of
         such series are payable (except as otherwise specified pursuant to
         Section 301 for the Securities of such series) equal to the aggregate
         amount proposed to be paid in respect of such Defaulted Interest or
         shall make arrangements satisfactory to the Trustee for such deposit on
         or prior to the date of the proposed payment, such money when deposited
         to be held in trust for the benefit of the Persons entitled to such
         Defaulted Interest as in this clause provided.

                                       34
<PAGE>   41
         Thereupon the Trustee shall fix a Special Record Date for the payment
         of such Defaulted Interest which shall be not more than 15 days and not
         less than 10 days prior to the date of the proposed payment and not
         less than 10 days after the receipt by the Trustee of the notice of the
         proposed payment. The Trustee shall promptly notify the Company of such
         Special Record Date and, in the name and at the expense of the Company,
         shall cause notice of the proposed payment of such Defaulted Interest
         and the Special Record Date therefor to be mailed, first-class postage
         prepaid, to each Holder of Registered Securities of such series at his
         address as it appears in the Security Register not less than 10 days
         prior to such Special Record Date. The Trustee may, in its discretion,
         in the name and at the expense of the Company, cause a similar notice
         to be published at least once in an Authorized Newspaper in each Place
         of Payment, but such publications shall not be a condition precedent to
         the establishment of such Special Record Date. Notice of the proposed
         payment of such Defaulted Interest and the Special Record Date therefor
         having been mailed as aforesaid, such Defaulted Interest shall be paid
         to the Persons in whose names the Registered Securities of such series
         (or their respective Predecessor Securities) are registered at the
         close of business on such Special Record Date and shall no longer be
         payable pursuant to the following clause (2). In case a Bearer Security
         of any series is surrendered at the office or agency in a Place of
         Payment for such series in exchange for a Registered Security of such
         series after the close of business at such office or agency on any
         Special Record Date and before the opening of business at such office
         or agency on the related proposed date for payment of Defaulted
         Interest, such Bearer Security shall be surrendered without the coupon
         relating to such proposed date of payment and Defaulted Interest will
         not be payable on such proposed date of payment in respect of the
         Registered Security issued in exchange for such Bearer Security, but
         will be payable only to the Holder of such coupon when due in
         accordance with the provisions of this Indenture.

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

         Subject to the foregoing provisions of this Section and Section 305,
each Security delivered under this Indenture upon registration of transfer of or
in exchange for or in lieu of any other Security shall carry the rights to
interest accrued and unpaid, and to accrue, which were carried by such other
Security.

         SECTION 308. Persons Deemed Owners. Prior to due presentment of a
Registered Security for registration of transfer, the Company, the Trustee and
any agent of the Company or the Trustee may treat the Person in whose name such
Registered Security is registered as the owner of such Security for the purpose
of receiving payment of principal of (and premium or

                                       35
<PAGE>   42
Make-Whole Amount, if any), and (subject to Sections 305 and 307) interest on,
such Registered Security and for all other purposes whatsoever, whether or not
such Registered Security be overdue, and neither the Company, the Trustee nor
any agent of the Company or the Trustee shall be affected by notice to the
contrary. All such payments so made to any such Person, or upon such Person's
order, shall be valid, and, to the extent of the sum or sums so paid, effectual
to satisfy and discharge the liability for money payable upon any such Security.

         Title to any Bearer Security and any coupons appertaining thereto shall
pass by delivery. The Company, the Trustee and any agent of the Company or the
Trustee may treat the Holder of any Bearer Security and the Holder of any coupon
as the absolute owner of such Security or coupon for the purpose of receiving
payment thereof or on account thereof and for all other purposes whatsoever,
whether or not such Security or coupon be overdue, and neither the Company, the
Trustee nor any agent of the Company or the Trustee shall be affected by notice
to the contrary.

         No Holder of any beneficial interest in any Global Security held on its
behalf by a depository shall have any rights under this Indenture with respect
to such Global Security and such depository shall be treated by the Company, the
Trustee, and any agent of the Company or the Trustee as the owner of such Global
Security for all purposes whatsoever. None of the Company, the Trustee, any
Paying Agent or the Security Registrar will have any responsibility or liability
for any aspect of the records relating to or payments made on account of
beneficial ownership interests of a Global Security or for maintaining,
supervising or reviewing any records relating to such beneficial ownership
interests.

         Notwithstanding the foregoing, with respect to any Global Security,
nothing herein shall prevent the Company, the Trustee, or any agent of the
Company or the Trustee, from giving effect to any written certification, proxy
or other authorization furnished by any depository, as a Holder, with respect to
such Global Security or impair, as between such depository and owners of
beneficial interests in such Global Security, the operation of customary
practices governing the exercise of the rights of such depository (or its
nominee) as Holder of such Global Security.

         SECTION 309. Cancellation. All Securities and coupons surrendered for
payment, redemption, repayment at the option of the Holder, registration of
transfer or exchange or for credit against any sinking fund payment shall, if
surrendered to any Person other than the Trustee, be delivered to the Trustee,
and any such Securities and coupons and Securities and coupons surrendered
directly to the Trustee for any such purpose shall be promptly cancelled by it.
The Company may at any time deliver to the Trustee for cancellation any
Securities previously authenticated and delivered hereunder which the Company
may have acquired in any manner whatsoever, and may deliver to the Trustee (or
to any other Person for delivery to the Trustee) for cancellation any Securities
previously authenticated hereunder which the Company has not issued and sold,
and all Securities so delivered shall be promptly cancelled by the Trustee. If
the Company shall so acquire any of the Securities, however, such 

                                       36
<PAGE>   43
acquisition shall not operate as a redemption or satisfaction of the
indebtedness represented by such Securities unless and until the same are
surrendered to the Trustee for cancellation. No Securities shall be
authenticated in lieu of or in exchange for any Securities cancelled as provided
in this Section, except as expressly permitted by this Indenture. Cancelled
Securities and coupons held by the Trustee shall be destroyed by the Trustee and
the Trustee shall deliver a certificate of such destruction to the Company,
unless the Trustee is otherwise directed by a Company Order.

         SECTION 310. Computation of Interest. Except as otherwise specified as
contemplated by Section 301 with respect to Securities of any series, interest
on the Securities of each series shall be computed on the basis of a 360-day
year consisting of twelve 30-day months.

                    ARTICLE FOUR - SATISFACTION AND DISCHARGE

         SECTION 401. Satisfaction and Discharge of Indenture. This Indenture
shall upon Company Request cease to be of further effect with respect to any
series of Securities specified in such Company Request (except as to any
surviving rights of registration of transfer or exchange of Securities of such
series herein expressly provided for), and the Trustee, upon receipt of a
Company Order, and at the expense of the Company, shall execute instruments in
form and substance satisfactory to the Trustee and the Company acknowledging
satisfaction and discharge of this Indenture as to such series when

                           (1) either

                           (A) all Securities of such series theretofore
                  authenticated and delivered and all coupons, if any,
                  appertaining thereto (other than (i) coupons appertaining to
                  Bearer Securities surrendered for exchange for Registered
                  Securities and maturing after such exchange, whose surrender
                  is not required or has been waived as provided in Section 305,
                  (ii) Securities and coupons of such series which have been

                  Securities called for redemption and maturing after the
                  relevant Redemption Date, whose surrender has been waived as
                  provided in Section 1106, and (iv) Securities and coupons of
                  such series for whose payment money has theretofore been
                  deposited in trust or segregated and held in trust by the
                  Company and thereafter repaid to the Company or discharged
                  from such trust, as provided in Section 1003) have been
                  delivered to the Trustee for cancellation; or

                           (B) all Securities of such series and, in the case of
                  (i) or (ii) below, any coupons appertaining thereto not
                  theretofore delivered to the Trustee for cancellation

                                       37
<PAGE>   44
                                    (i) have become due and payable, or

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

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

                  and the Company, in the case of (i), (ii) or (iii) above, has
                  irrevocably deposited or caused to be deposited with the
                  Trustee as trust funds in trust for the purpose an amount in
                  the currency or currencies, currency unit or units or
                  composite currency or currencies in which the Securities of
                  such series are payable, sufficient to pay and discharge the
                  entire indebtedness on such Securities and such coupons not
                  theretofore delivered to the Trustee for cancellation, for
                  principal (and premium or Make-Whole Amount, if any) and
                  interest to the date of such deposit (in the case of
                  Securities which have become due and payable) or to the Stated
                  Maturity or Redemption Date, as the case may be;

                           (2) the Company has paid or caused to be paid all
         other sums payable hereunder by the Company; and

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

Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Company to the Trustee and any predecessor Trustee under
Section 606, the obligations of the Company to any Authenticating Agent under
Section 611 and, if money shall have been deposited with and held by the Trustee
pursuant to subclause (B) of clause (1) of this Section, the obligations of the
Trustee under Section 402 and the last paragraph of Section 1003 shall survive.

         SECTION 402. Application of Trust Funds. Subject to the provisions of
the last paragraph of Section 1003, all money deposited with the Trustee
pursuant to Section 401 shall be held in trust and applied by it, in accordance
with the provisions of the Securities, the coupons and this Indenture, to the
payment, either directly or through any Paying Agent (including the Company
acting as its own Paying Agent) as the Trustee may determine, to the Persons
entitled thereto, of the principal (and premium or Make-Whole Amount, if any),
and any interest for whose payment such money has been deposited with or
received by the


                                       38
<PAGE>   45
Trustee, but such money need not be segregated from other funds except to the
extent required by law.


                             ARTICLE FIVE - REMEDIES

         SECTION 501. Events of Default. "Event of Default," wherever used
herein with respect to any particular series of Securities, means any one of the
following events (whatever the reason for such Event of Default and whether or
not it shall be voluntary or involuntary or be effected by operation of law or
pursuant to any judgment, decree or order of any court or any order, rule or
regulation of any administrative or governmental body):

                           (1) default in the payment of any interest on any
         Security of that series or of any coupon appertaining thereto, when
         such interest or coupon becomes due and payable, and continuance of
         such default for a period of 30 days; or

                           (2) default in the payment of the principal of (or
         premium or Make-Whole Amount, if any, on) any Security of that series
         when it becomes due and payable at its Maturity; or

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

                           (4) default in the performance, or breach, of any
         covenant or warranty of the Company in this Indenture with respect to
         any Security of that series (other than a covenant or warranty a
         default in whose performance or whose breach is elsewhere in this
         Section specifically dealt with), and continuance of such default or
         breach for a period of 60 days after there has been given, by
         registered or certified mail, to the Company by the Trustee or to the
         Company and the Trustee by the Holders of at least 25% in principal
         amount of the Outstanding Securities of that series a written notice
         specifying such default or breach and requiring it to be remedied and
         stating that such notice is a "Notice of Default" hereunder; or

                           (5) default under any bond, debenture, note,
         mortgage, indenture or instrument under which there may be issued or by
         which there may be secured or evidenced any indebtedness for money
         borrowed by the Company (or by any Subsidiary, the repayment of which
         the Company has guaranteed or for which the Company is directly
         responsible or liable as obligor or guarantor), having an aggregate
         principal amount outstanding of at least $25,000,000, whether such
         indebtedness now exists or shall hereafter be created, which default
         shall have resulted in such indebtedness becoming or being declared due
         and payable prior to the date on which it would otherwise have become
         due and payable, without such indebtedness having been discharged, or
         such acceleration having been rescinded or annulled, within a period of


                                       39
<PAGE>   46
         10 days after there shall have been given, by registered or certified
         mail, to the Company by the Trustee or to the Company and the Trustee
         by the Holders of at least 10% in principal amount of the Outstanding
         Securities of that series a written notice specifying such default and
         requiring the Company to cause such indebtedness to be discharged or
         cause such acceleration to be rescinded or annulled and stating that
         such notice is a "Notice of Default" hereunder; or

                           (6) the Company or any Significant Subsidiary
         pursuant to or within the meaning of any Bankruptcy Law:

                                    (A) commences a voluntary case,

                                    (B) consents to the entry of an order for
                  relief against it in an involuntary case,

                                    (C) consents to the appointment of a
                  Custodian of it or for all or substantially all of its
                  property, or

                                    (D) makes a general assignment for the
                  benefit of its creditors; or

                           (7) a court of competent jurisdiction enters an order
         or decree under any Bankruptcy Law that:

                                    (A) is for relief against the Company or any
                  Significant Subsidiary in an involuntary case,

                                    (B) appoints a Custodian of the Company or
                  any Significant Subsidiary or for all or substantially all of
                  either of its property, or

                                    (C) orders the liquidation of the Company or
                  any Significant Subsidiary, and the order or decree remains
                  unstayed and in effect for 90 days; or

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

As used in this Section 501, the term "Bankruptcy Law" means title 11, U.S. Code
or any similar Federal or state law for the relief of debtors and the term
"Custodian" means any receiver, trustee, assignee, liquidator or other similar
official under any Bankruptcy Law.

         SECTION 502. Acceleration of Maturity; Rescission and Annulment. If an
Event of Default with respect to Securities of any series at the time
Outstanding occurs and is


                                       40
<PAGE>   47
continuing, then and in every such case the Trustee or the Holders of not less
than 25% in principal amount of the Outstanding Securities of that series may
declare the principal amount (or, if Securities of that Series are Original
Issue Discount Securities or Indexed Securities, such portion of the principal
as may be specified in the terms thereof) of all the Securities of that series
to be due and payable immediately, by a notice in writing to the Company (and to
the Trustee if given by the Holders), and upon any such declaration such
principal or specified portion thereof shall become immediately due and payable.

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

                           (1) the Company has paid or deposited with the
         Trustee a sum sufficient to pay in the currency, currency unit or
         composite currency in which the Securities of such series are payable
         (except as otherwise specified pursuant to Section 301 for the
         Securities of such series):

                                    (A) all overdue installments of interest on
                  all Outstanding Securities of that series and any related
                  coupons,

                                    (B) the principal of (and premium or
                  Make-Whole Amount, if any, on) any Outstanding Securities of
                  that series which have become due otherwise than by such
                  declaration of acceleration and interest thereon at the rate
                  or rates borne by or provided for in such Securities,

                                    (C) to the extent that payment of such
                  interest is lawful, interest upon overdue installments of
                  interest at the rate or rates borne by or provided for in such
                  Securities, and

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

                           (2) all Events of Default with respect to Securities
         of that series, other than the nonpayment of the principal of (or
         premium or Make-Whole Amount, if any) or interest on Securities of that
         series which have become due solely by such declaration of
         acceleration, have been cured or waived as provided in Section 513.

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


                                       41
<PAGE>   48
         SECTION 503. Collection of Indebtedness and Suits for Enforcement by
Trustee. The Company covenants that if:

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

                           (2) default is made in the payment of the principal
         of (or premium or Make-Whole Amount, if any, on) any Security of any
         series at its Maturity,

then the Company will, upon demand of the Trustee, pay to the Trustee, for the
benefit of the Holders of such Securities of such series and coupons, the whole
amount then due and payable on such Securities and coupons for principal (and
premium or Make-Whole Amount, if any) and interest, with interest upon any
overdue principal (and premium or Make-Whole Amount, if any) and, to the extent
that payment of such interest shall be legally enforceable, upon any overdue
installments of interest at the rate or rates borne by or provided for in such
Securities, and, in addition thereto, such further amount as shall be sufficient
to cover the costs and expenses of collection, including the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel.

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

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

         SECTION 504. Trustee May File Proofs of Claim. In case of the pendency
of any receivership, insolvency, liquidation, bankruptcy, reorganization,
arrangement, adjustment, composition or other judicial proceeding relative to
the Company or any other obligor upon the Securities or the property of the
Company or of such other obligor or their creditors, the Trustee (irrespective
of whether the principal of the Securities of any series shall then be due and
payable as therein expressed or by declaration or otherwise and irrespective of
whether the Trustee shall have made any demand on the Company for the payment of
overdue principal,


                                       42
<PAGE>   49
premium or Make-Whole Amount, if any, or interest) shall be entitled and
empowered, by intervention in such proceeding or otherwise:

                           (i) to file and prove a claim for the whole amount,
         or such lesser amount as may be provided for in the Securities of such
         series, of principal (and premium or Make-Whole Amount, if any) and
         interest owing and unpaid in respect of the Securities and to file such
         other papers or documents as may be necessary or advisable in order to
         have the claims of the Trustee (including any claim for the reasonable
         compensation, expenses, disbursements and advances of the Trustee, its
         agents and counsel) and of the Holders allowed in such judicial
         proceeding, and

                           (ii) to collect and receive any moneys or other
         property payable or deliverable on any such claims and to distribute
         the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator (or
other similar official) in any such judicial proceeding is hereby authorized by
each Holder of Securities of such series and coupons to make such payments to
the Trustee, and in the event that the Trustee shall consent to the making of
such payments directly to the Holders, to pay to the Trustee any amount due to
it for the reasonable compensation, expenses, disbursements and advances of the
Trustee and any predecessor Trustee, their agents and counsel, and any other
amounts due the Trustee or any predecessor Trustee under Section 606.

         Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder of a Security
or coupon any plan of reorganization, arrangement, adjustment or composition
affecting the Securities or coupons or the rights of any Holder thereof, or to
authorize the Trustee to vote in respect of the claim of any Holder of a
Security or coupon in any such proceeding.

         In any proceedings brought by the Trustee (and also any proceedings
involving the interpretation of any provision of this Indenture to which the
Trustee shall be a party) the Trustee shall be held to represent all the Holders
of the Securities, and it shall not be necessary to make any Holders of the
Securities parties to any such proceedings.

         SECTION 505. Trustee May Enforce Claims Without Possession of
Securities or Coupons. All rights of action and claims under this Indenture or
any of the Securities or coupons may be prosecuted and enforced by the Trustee
without the possession of any of the Securities or coupons or the production
thereof in any proceeding relating thereto, and any such proceeding instituted
by the Trustee shall be brought in its own name as trustee of an express trust,
and any recovery of judgment shall, after provision for the payment of the
reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and counsel, be for the ratable benefit of the Holders of the
Securities and coupons in respect of which such judgment has been recovered.


                                       43
<PAGE>   50
         SECTION 506. Application of Money Collected. Any money collected by the
Trustee pursuant to this Article shall be applied in the following order, at the
date or dates fixed by the Trustee and, in case of the distribution of such
money on account of principal (or premium or Make-Whole Amount, if any) or
interest, upon presentation of the Securities or coupons, or both, as the case
may be, and the notation thereon of the payment if only partially paid and upon
surrender thereof if fully paid:

                  FIRST: To the payment of all amounts due the Trustee and any
         predecessor Trustee under Section 606;

                  SECOND: To the payment of the amounts then due and unpaid upon
         the Securities and coupons for principal (and premium or Make-Whole
         Amount, if any) and interest, in respect of which or for the benefit of
         which such money has been collected, ratably, without preference or
         priority of any kind, according to the aggregate amounts due and
         payable on such Securities and coupons for principal (and premium or
         Make- Whole Amount, if any) and interest, respectively; and

                  THIRD: To the payment of the remainder, if any, to the
         Company.

         SECTION 507. Limitation on Suits. No Holder of any Security of any
series or any related coupon shall have any right to institute any proceeding,
judicial or otherwise, with respect to this Indenture, or for the appointment of
a receiver or trustee, or for any other remedy hereunder, unless:

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

                           (2) the Holders of not less than 25% in principal
         amount of the Outstanding Securities of that series shall have made
         written request to the Trustee to institute proceedings in respect of
         such Event of Default in its own name as Trustee hereunder;

                           (3) such Holder or Holders have offered to the
         Trustee indemnity reasonably satisfactory to the Trustee against the
         costs, expenses and liabilities to be incurred in compliance with such
         request;

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

                           (5) no direction inconsistent with such written
         request has been given to the Trustee during such 60-day period by the
         Holders of a majority in principal amount of the Outstanding Securities
         of that series;


                                       44
<PAGE>   51
it being understood and intended that no one or more of such Holders shall have
any right in any manner whatever by virtue of, or by availing of, any provision
of this Indenture to affect, disturb or prejudice the rights of any other of
such Holders, or to obtain or to seek to obtain priority or preference over any
other of such Holders or to enforce any right under this Indenture, except in
the manner herein provided and for the equal and ratable benefit of all such
Holders.

         SECTION 508. Unconditional Right of Holders to Receive Principal,
Premium or Make-Whole Amount, if any, and Interest. Notwithstanding any other
provision in this Indenture, the Holder of any Security or coupon shall have the
right which is absolute and unconditional to receive payment of the principal of
(and premium or Make-Whole Amount, if any) and (subject to Sections 305 and 307)
interest on such Security or payment of such coupon on the respective due dates
expressed in such Security or coupon (or, in the case of redemption, on the
Redemption Date) and to institute suit for the enforcement of any such payment,
and such rights shall not be impaired without the consent of such Holder.

         SECTION 509. Restoration of Rights and Remedies. If the Trustee or any
Holder of a Security or coupon has instituted any proceeding to enforce any
right or remedy under this Indenture and such proceeding has been discontinued
or abandoned for any reason, or has been determined adversely to the Trustee or
to such Holder, then and in every such case, the Company, the Trustee and the
Holders of Securities and coupons shall, subject to any determination in such
proceeding, be restored severally and respectively to their former positions
hereunder and thereafter all rights and remedies of the Trustee and the Holders
shall continue as though no such proceeding had been instituted.

         SECTION 510. Rights and Remedies Cumulative. Except as otherwise
provided with respect to the replacement or payment of mutilated, destroyed,
lost or stolen Securities or coupons in the last paragraph of Section 306, no
right or remedy herein conferred upon or reserved to the Trustee or to the
Holders of Securities or coupons is intended to be exclusive of any other right
or remedy, and every right and remedy shall, to the extent permitted by law, be
cumulative and in addition to every other right and remedy given hereunder or
now or hereafter existing at law or in equity or otherwise. The assertion or
employment of any right or remedy hereunder, or otherwise, shall not prevent the
concurrent assertion or employment of any other appropriate right or remedy.

         SECTION 511. Delay or Omission Not Waiver. No delay or omission of the
Trustee or of any Holder of any Security or coupon to exercise any right or
remedy accruing upon any Event of Default shall impair any such right or remedy
or constitute a waiver of any such Event of Default or an acquiescence therein.
Every right and remedy given by this Article or by law to the Trustee or to the
Holders may be exercised from time to time, and as often as may be deemed
expedient, by the Trustee or by the Holders of Securities or coupons, as the
case may be.


                                       45
<PAGE>   52
         SECTION 512. Control by Holders of Securities. The Holders of not less
than a majority in principal amount of the Outstanding Securities of any series
shall have the right to direct the time, method and place of conducting any
proceeding for any remedy available to the Trustee or exercising any trust or
power conferred on the Trustee with respect to the Securities of such series,
provided that

                           (1) such direction shall not be in conflict with any
         rule of law or with this Indenture,

                           (2) the Trustee may take any other action deemed
         proper by the Trustee which is not inconsistent with such direction,
         and

                           (3) the Trustee need not take any action which might
         involve it in personal liability or be unduly prejudicial to the
         Holders of Securities of such series not joining therein.

         Nothing in this Indenture shall impair the right of the Trustee in its
discretion to take any action deemed proper by the Trustee and which is not
inconsistent with such direction by Holders.

         SECTION 513. Waiver of Past Defaults. The Holders of not less than a
majority in principal amount of the Outstanding Securities of any series may on
behalf of the Holders of all the Securities of such series and any related
coupons waive any past default hereunder with respect to such series and its
consequences, except a default

                           (1) in the payment of the principal of (or premium or
         Make-Whole Amount, if any) or interest on any Security of such series
         or any related coupons, or

                           (2) in respect of a covenant or provision hereof
         which under Article Nine cannot be modified or amended without the
         consent of the Holder of each Outstanding Security of such series
         affected.

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

         SECTION 514. Waiver of Usury, Stay or Extension Laws. The Company
covenants (to the extent that it may lawfully do so) that it will not at any
time insist upon, or plead, or in any manner whatsoever claim or take the
benefit or advantage of, any usury, stay or extension law wherever enacted, now
or at any time hereafter in force, which may affect the covenants or the
performance of this Indenture; and the Company (to the extent that it may
lawfully do so) hereby expressly waives all benefit or advantage of any such
law, and covenants that it will


                                       46
<PAGE>   53
not hinder, delay or impede the execution of any power herein granted to the
Trustee, but will suffer and permit the execution of every such power as though
no such law had been enacted.

         SECTION 515. Undertaking for Costs. All parties to this Indenture
agree, and each Holder of any Security by his acceptance thereof shall be deemed
to have agreed, that any court may in its discretion require, in any suit for
the enforcement of any right or remedy under this Indenture, or in any suit
against the Trustee for any action taken or omitted by it as Trustee, the filing
by any party litigant in such suit of an undertaking to pay the costs of such
suit, and that such court may in its discretion assess reasonable costs,
including reasonable attorneys' fees, against any party litigant in such suit
having due regard to the merits and good faith of the claims or defenses made by
such party litigant; but the provisions of this Section shall not apply to any
suit instituted by the Trustee, to any suit instituted by any Holder, or group
of Holders, holding in the aggregate more than 10% in principal amount of the
Outstanding Securities of any series, or to any suit instituted by any Holder
for the enforcement of the payment of the principal of (or premium or Make-Whole
Amount, if any) or interest on any Security on or after the respective Stated
Maturities expressed in such Security (or, in the case of redemption, on or
after the Redemption Date).


                            ARTICLE SIX - THE TRUSTEE

         SECTION 601. Notice of Defaults. Within 90 days after the occurrence of
any default hereunder with respect to the Securities of any series, the Trustee
shall transmit in the manner and to the extent provided in TIA Section 313(c),
notice of such default hereunder known to the Trustee, unless such default shall
have been cured or waived; provided, however, that, except in the case of a
default in the payment of the principal of (or premium or Make-Whole Amount, if
any) or interest on any Security of such series, or in the payment of any
sinking or purchase fund installment with respect to the Securities of such
series, the Trustee shall be protected in withholding such notice if and so long
as the board of directors, the executive committee, or a trust commitee of
directors and/or Responsible Officers of the Trustee in good faith determine
that the withholding of such notice is in the interests of the Holders of the
Securities and coupons of such series; and provided further that in the case of
any default or breach of the character specified in Section 501(4) with respect
to the Securities and coupons of such series, no such notice to Holders shall be
given until at least 60 days after the occurrence thereof. For the purpose of
this Section, the term "default" means any event which is, or after notice or
lapse of time or both would become, an Event of Default with respect to the
Securities of such series.

         SECTION 602. Certain Rights of Trustee. Subject to the provisions of
TIA Section 315(a) through 315(d):

                           (1) the Trustee may rely and shall be protected in
         acting or refraining from acting upon any resolution, certificate,
         statement, instrument, opinion, report,


                                       47
<PAGE>   54
         notice, request, direction, consent, order, bond, debenture, note,
         coupon or other paper or document believed by it to be genuine and to
         have been signed or presented by the proper party or parties;

                           (2) any request or direction of the Company mentioned
         herein shall be sufficiently evidenced by a Company Request or Company
         Order (other than delivery of any Security, together with any coupons
         appertaining thereto, to the Trustee for authentication and delivery
         pursuant to Section 303 which shall be sufficiently evidenced as
         provided therein) and any resolution of the Board of Directors may be
         sufficiently evidenced by a Board Resolution;

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

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

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

                           (6) the Trustee shall not be bound to make any
         investigation into the facts or matters stated in any resolution,
         certificate, statement, instrument, opinion, report, notice, request,
         direction, consent, order, bond, debenture, note, coupon or other paper
         or document, unless requested in writing so to do by the Holders of not
         less than a majority in aggregate principal amount of the Outstanding
         Securities of any series; provided that, if the payment within a
         reasonable time to the Trustee of the costs, expenses or liabilities
         likely to be incurred by it in the making of such investigation is, in
         the opinion of the Trustee, not reasonably assured to the Trustee by
         the security afforded to it by the terms of this Indenture, the Trustee
         may require reasonable indemnity against such expenses or liabilities
         as a condition to proceeding; the reasonable expenses of every such
         examination shall be paid by the Holders or, if paid by the Trustee,
         shall be repaid by the Holders upon demand. The Trustee, in its
         discretion, may make such further inquiry or


                                       48
<PAGE>   55
         investigation into such facts or matters as it may see fit, and, if the
         Trustee shall determine to make such further inquiry or investigation,
         it shall be entitled to examine the books, records and premises of the
         Company, relevant to the facts or matters that are the subject of its
         inquiry, personally or by agent or attorney;

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

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

         The Trustee shall not be required to expend or risk its own funds or
otherwise incur any financial liability in the performance of any of its duties
hereunder, or in the exercise of any of its rights or powers, if it shall have
reasonable grounds for believing that repayment of such funds or adequate
indemnity against such risk or liability is not reasonably assured to it.

         Except during the continuance of an Event of Default, the Trustee
undertakes to perform only such duties as are specifically set forth in this
Indenture, and no implied covenants or obligations shall be read into this
Indenture against the Trustee.

         SECTION 603. Not Responsible for Recitals or Issuance of Securities.
The recitals contained herein and in the Securities, except the Trustee's
certificate of authentication, and in any coupons shall be taken as the
statements of the Company, and neither the Trustee nor any Authenticating Agent
assumes any responsibility for their correctness. The Trustee makes no
representations as to the validity or sufficiency of this Indenture or of the
Securities or coupons, except that the Trustee represents that it is duly
authorized to execute and deliver this Indenture, authenticate the Securities
and perform its obligations hereunder. Neither the Trustee nor any
Authenticating Agent shall be accountable for the use or application by the
Company of Securities or the proceeds thereof.

         SECTION 604. May Hold Securities. The Trustee, any Paying Agent,
Security Registrar, Authenticating Agent or any other agent of the Company, in
its individual or any other capacity, may become the owner or pledgee of
Securities and coupons and, subject to TIA Sections 310(b) and 311, may
otherwise deal with the Company with the same rights it would have if it were
not Trustee, Paying Agent, Security Registrar, Authenticating Agent or such
other agent.

         SECTION 605. Money Held in Trust. Money held by the Trustee in trust
hereunder need not be segregated from other funds except to the extent required
by law. The Trustee shall be under no liability for interest on any money
received by it hereunder except as otherwise agreed with the Company.


                                       49
<PAGE>   56
         SECTION 606.  Compensation and Reimbursement.  The Company agrees:

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

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

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

         When the Trustee incurs expenses or renders services in connection with
an Event of Default specified in Section 501(7) or Section 501(8), the expenses
(including the reasonable charges and expenses of its counsel) and the
compensation for the services are intended to constitute expenses of
administration under any applicable Federal or state bankruptcy, insolvency or
other similar law.

         As security for the performance of the obligations of the Company under
this Section, the Trustee shall have a lien prior to the Securities upon all
property and funds held or collected by the Trustee as such, except funds held
in trust for the payment of principal of (or premium or Make-Whole Amount, if
any) or interest on particular Securities or any coupons.

         The provisions of this Section shall survive the termination of this
Indenture.

         SECTION 607. Corporate Trustee Required; Eligibility; Conflicting
Interests. There shall at all times be a Trustee hereunder which shall be
eligible to act as Trustee under TIA Section 310(a)(1) and shall have at all
times a combined capital and surplus of at least $50,000,000. If the Trustee
publishes reports of condition at least annually, pursuant to law or the
requirements of Federal, state, territorial or District of Columbia supervising
or examining authority, then for the purposes of this Section, the combined
capital and surplus of the Trustee shall be deemed to be its combined capital
and surplus as set forth in its most recent report of condition so published. If
at any time the Trustee shall cease to be eligible in accordance with the
provisions of this Section, it shall resign immediately in the manner and with
the effect


                                       50
<PAGE>   57
hereinafter specified in this Article. Neither the Company nor any Person
directly or indirectly controlling, controlled by, or under common control with
the Company shall serve as Trustee.

         SECTION 608. Resignation and Removal; Appointment of Successor.

                  (a) No resignation or removal of the Trustee and no
appointment of a successor Trustee pursuant to this Article shall become
effective until the acceptance of appointment by the successor Trustee in
accordance with the applicable requirements of Section 609.

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

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

                  (d) If at any time:

                           (1) the Trustee shall fail to comply with the
         provisions of TIA Section 310(b) after written request therefor by the
         Company or by any Holder of a Security who has been a bona fide Holder
         of a Security for at least six months, or

                           (2) the Trustee shall cease to be eligible under
         Section 607 and shall fail to resign after written request therefor by
         the Company or by any Holder of a Security who has been a bona fide
         Holder of a Security for at least six months, or

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

then, in any such case, (i) the Company by or pursuant to a Board Resolution may
remove the Trustee and appoint a successor Trustee with respect to all
Securities, or (ii) subject to TIA Section 315(e), any Holder of a Security who
has been a bona fide Holder of a Security for at least six months may, on behalf
of himself and all others similarly situated, petition any court of competent
jurisdiction for the removal of the Trustee with respect to all Securities and
the appointment of a successor Trustee or Trustees.


                                       51
<PAGE>   58
                  (e) If the Trustee shall resign, be removed or become
incapable of acting, or if a vacancy shall occur in the office of Trustee for
any cause with respect to the Securities of one or more series, the Company, by
or pursuant to a Board Resolution, shall promptly appoint a successor Trustee or
Trustees with respect to the Securities of that or those series (it being
understood that any such successor Trustee may be appointed with respect to the
Securities of one or more or all of such series and that at any time there shall
be only one Trustee with respect to the Securities of any particular series).
If, within one year after such resignation, removal or incapability, or the
occurrence of such vacancy, a successor Trustee with respect to the Securities
of any series shall be appointed by Act of the Holders of a majority in
principal amount of the Outstanding Securities of such series delivered to the
Company and the retiring Trustee, the successor Trustee so appointed shall,
forthwith upon its acceptance of such appointment, become the successor Trustee
with respect to the Securities of such series and to that extent supersede the
successor Trustee appointed by the Company. If no successor Trustee with respect
to the Securities of any series shall have been so appointed by the Company or
the Holders of Securities and accepted appointment in the manner hereinafter
provided, any Holder of a Security who has been a bona fide Holder of a Security
of such series for at least six months may, on behalf of himself and all others
similarly situated, petition any court of competent jurisdiction for the
appointment of a successor Trustee with respect to Securities of such series.

                  (f) The Company shall give notice of each resignation and each
removal of the Trustee with respect to the Securities of any series and each
appointment of a successor Trustee with respect to the Securities of any series
in the manner provided for notices to the Holders of Securities in Section 106.
Each notice shall include the name of the successor Trustee with respect to the
Securities of such series and the address of its Corporate Trust Office.

         SECTION 609. Acceptance of Appointment by Successor. (a) In case of the
appointment hereunder of a successor Trustee with respect to all Securities,
every such successor Trustee so appointed shall execute, acknowledge and deliver
to the Company and to the retiring Trustee an instrument accepting such
appointment, and thereupon the resignation or removal of the retiring Trustee
shall become effective and such successor Trustee, without any further act, deed
or conveyance, shall become vested with all the rights, powers, trusts and
duties of the retiring Trustee; but, on request of the Company or the successor
Trustee, such retiring Trustee shall, upon payment of its charges, execute and
deliver an instrument transferring to such successor Trustee all the rights,
powers and trusts of the retiring Trustee, and shall duly assign, transfer and
deliver to such successor Trustee all property and money held by such retiring
Trustee hereunder, subject nevertheless to its claim, if any, provided for in
Section 606.

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


                                       52
<PAGE>   59
an indenture supplemental hereto, pursuant to Article Nine hereof, wherein each
successor Trustee shall accept such appointment and which (1) shall contain such
provisions as shall be necessary or desirable to transfer and confirm to, and to
vest in, each successor Trustee all the rights, powers, trusts and duties of the
retiring Trustee with respect to the Securities of that or those series to which
the appointment of such successor Trustee relates, (2) if the retiring Trustee
is not retiring with respect to all Securities, shall contain such provisions as
shall be deemed necessary or desirable to confirm that all the rights, powers,
trusts and duties of the retiring Trustee with respect to the Securities of that
or those series as to which the retiring Trustee is not retiring shall continue
to be vested in the retiring Trustee, and (3) shall add to or change any of the
provisions of this Indenture as shall be necessary to provide for or facilitate
the administration of the trusts hereunder by more than one Trustee, it being
understood that nothing herein or in such supplemental indenture shall
constitute such Trustees co-trustees of the same trust and that each such
Trustee shall be trustee of a trust or trusts hereunder separate and apart from
any trust or trusts hereunder administered by any other such Trustee; and upon
the execution and delivery of such supplemental indenture the resignation or
removal of the retiring Trustee shall become effective to the extent provided
therein and each such successor Trustee, without any further act, deed or
conveyance, shall become vested with all the rights, powers, trusts and duties
of the retiring Trustee with respect to the Securities of that or those series
to which the appointment of such successor Trustee relates; but, on request of
the Company or any successor Trustee, such retiring Trustee shall duly assign,
transfer and deliver to such successor Trustee all property and money held by
such retiring Trustee hereunder with respect to the Securities of that or those
series to which the appointment of such successor Trustee relates.

                  (c) Upon request of any such successor Trustee, the Company
shall execute any and all instruments for more fully and certainly vesting in
and confirming to such successor Trustee all such rights, powers and trusts
referred to in paragraph (a) or (b) of this Section 609, as the case may be.

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

         SECTION 610. Merger, Conversion, Consolidation or Succession to
Business. Any corporation into which the Trustee may be merged or converted or
with which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to all or substantially all of the corporate trust
business of the Trustee, shall be the successor of the Trustee hereunder,
provided such corporation shall be otherwise qualified and eligible under this
Article, without the execution or filing of any paper or any further act on the
part of any of the parties hereto. In case any Securities or coupons shall have
been authenticated, but not delivered, by the Trustee then in office, any
successor by merger, conversion or consolidation to such authenticating Trustee
may adopt such authentication and deliver the Securities or coupons so
authenticated with the same effect as if such successor Trustee had itself
authenticated such


                                       53
<PAGE>   60
Securities or coupons. In case any Securities or coupons shall not have been
authenticated by such predecessor Trustee, any such successor Trustee may
authenticate and deliver such Securities or coupons, in either its own name or
that of its predecessor Trustee, with the full force and effect which this
Indenture provides for the certificate of authentication of the Trustee.

         SECTION 611. Appointment of Authenticating Agent. At any time when any
of the Securities remain Outstanding, the Trustee may appoint an Authenticating
Agent or Agents with respect to one or more series of Securities which shall be
authorized to act on behalf of the Trustee to authenticate Securities of such
series issued upon exchange, registration of transfer or partial redemption or
repayment thereof, and Securities so authenticated shall be entitled to the
benefits of this Indenture and shall be valid and obligatory for all purposes as
if authenticated by the Trustee hereunder. Any such appointment shall be
evidenced by an instrument in writing signed by a Responsible Officer of the
Trustee, a copy of which instrument shall be promptly furnished to the Company.
Wherever reference is made in this Indenture to the authentication and delivery
of Securities by the Trustee or the Trustee's certificate of authentication,
such reference shall be deemed to include authentication and delivery on behalf
of the Trustee by an Authenticating Agent and a certificate of authentication
executed on behalf of the Trustee by an Authenticating Agent. Each
Authenticating Agent shall be acceptable to the Company and shall at all times
be a bank or trust company or corporation organized and doing business and in
good standing under the laws of the United States of America or of any state or
the District of Columbia, authorized under such laws to act as Authenticating
Agent, having a combined capital and surplus of not less than $50,000,000 and
subject to supervision or examination by Federal or state authorities. If such
Authenticating Agent publishes reports of condition at least annually, pursuant
to law or the requirements of the aforesaid supervising or examining authority,
then for the purposes of this Section, the combined capital and surplus of such
Authenticating Agent shall be deemed to be its combined capital and surplus as
set forth in its most recent report of condition so published. In case at any
time an Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, such Authenticating Agent shall resign immediately
in the manner and with the effect specified in this Section.

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

         An Authenticating Agent for any series of Securities may at any time
resign by giving written notice of resignation to the Trustee for such series
and to the Company. The Trustee for any series of Securities may at any time
terminate the agency of an Authenticating Agent by


                                       54
<PAGE>   61
giving written notice of termination to such Authenticating Agent and to the
Company. Upon receiving such a notice of resignation or upon such a termination,
or in case at any time such Authenticating Agent shall cease to be eligible in
accordance with the provisions of this Section, the Trustee for such series may
appoint a successor Authenticating Agent which shall be acceptable to the
Company and shall give notice of such appointment to all Holders of Securities
of the series with respect to which such Authenticating Agent will serve in the
manner set forth in Section 106. Any successor Authenticating Agent upon
acceptance of its appointment hereunder shall become vested with all the rights,
powers and duties of its predecessor hereunder, with like effect as if
originally named as an Authenticating Agent herein. No successor Authenticating
Agent shall be appointed unless eligible under the provisions of this Section.

         The Company agrees to pay to each Authenticating Agent from time to
time reasonable compensation including reimbursement of its reasonable expenses
for its services under this Section.

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

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

         SECTION 612.  Certain Duties and Responsibilities of the Trustee.

         (a) With respect to the Securities of any series, except during the
continuance of an Event of Default with respect to the Securities of such
series:

                  (1) the Trustee undertakes to perform such duties and only
         such duties as are specifically set forth in this Indenture, and no
         implied covenants or obligations shall be read into this Indenture
         against the Trustee; and

                                       55
<PAGE>   62
                  (2) in the absence of bad faith on its part, the Trustee may
         conclusively rely, as to the truth of the statements and the
         correctness of the opinions expressed therein, upon certificates or
         opinions furnished to the Trustee and conforming to the requirements of
         this Indenture; but in the case of any such certificates or opinions
         which by any provision hereof are specifically required to be furnished
         to the Trustee, the Trustee shall be under a duty to examine the same
         to determine whether or not they conform to the requirements of this
         Indenture, but shall not be under any duty to verify the contents or
         accuracy thereof.

         (b) In case an Event of Default with respect to the Securities of any
series has occurred and is continuing, the Trustee shall, with respect to
Securities of such series, exercise such of the rights and powers vested in it
by this Indenture, and use the same degree of care and skill in their exercise,
as a prudent man would exercise or use under the circumstances in the conduct of
his own affairs.

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

                  (1) this Subsection shall not be construed to limit the effect
         of Subsection (a) of this Section;

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

                  (3) the Trustee shall not be liable with respect to any action
         taken or omitted to be taken by it in good faith in accordance with the
         direction of the Holders of a majority in principal amount of the
         Outstanding Securities of any series relating to the time, method and
         place of conducting any proceeding for any remedy available to the
         Trustee, or exercising any trust or power conferred upon the Trustee,
         under this Indenture with respect to the Securities of such series; and

                  (4) no provision of this Indenture shall require the Trustee
         to expend or risk its own funds or otherwise incur any financial
         liability in the performance of any of its duties hereunder, or in the
         exercise of any of its rights or powers, if it shall have reasonable
         grounds for believing that repayment of such funds or adequate
         indemnity against such risk or liability is not reasonably assured to
         it.

         (d) Whether or not therein expressly so provided, every provision of
this Indenture relating to the conduct or affecting the liability of or
affording protection to the Trustee shall be subject to the provisions of this
Section 612.

         SECTION 701. Disclosure of Names and Addresses of Holders. Every Holder
of Securities or coupons, by receiving and holding the same, agrees with the
Company and the Trustee that neither the Company nor the Trustee nor any
Authenticating Agent nor any Paying Agent nor any Security Registrar shall be
held accountable by reason of the disclosure of any information as to the names
and addresses of the Holders of Securities in accordance with TIA Section 312,
regardless of the source from which such information was derived, and that the
Trustee shall not be held accountable by reason of mailing any material pursuant
to a request made under TIA Section 312(b).

[_________________], 199_. A copy of each such report shall, at the time of such
transmission to Holders, be filed by the Trustee with each stock exchange, if

Company. The Company will notify the Trustee when any Securities are listed on
any stock exchange.

         SECTION 703. Reports by Company. The Company will:

                           (1) file with the Trustee, within 15 days after the

         annual reports and of the information, documents and other reports (or
         copies of such portions of any of the foregoing as the Commission may

         may be required to file with the Commission pursuant to Section 13 or
         Section 15(d) of the Securities Exchange Act of 1934; or, if the

         from time to time by the Commission, such of the supplementary and
         periodic information, documents and reports which may be required

         respect of a security listed and registered on a national securities
         exchange as may be prescribed from time to time in such rules and
         regulations;

                  (a) semiannually, not later than 15 days after the Regular
Record Date for interest for each series of Securities, a list, in such form as
the Trustee may reasonably require, of the names and addresses of the Holders of
Registered Securities of such series as of such Regular Record Date, or if there
is no Regular Record Date for interest for such series of Securities,
semiannually, upon such dates as are set forth in the Board Resolution or
indenture supplemental hereto authorizing such series, and

                  (b) at such other times as the Trustee may request in writing,
within 30 days after the receipt by the Company of any such request, a list of
similar form and content as of a date not more than 15 days prior to the time
such list is furnished,

        ARTICLE EIGHT - CONSOLIDATION, MERGER, SALE, LEASE OR CONVEYANCE

         SECTION 801. Consolidations and Mergers of Company and Sales, Leases
and Conveyances Permitted Subject to Certain Conditions. The Company may
consolidate with, or sell, lease or convey all or substantially all of its
assets to, or merge with or into any other corporation, provided that in any
such case, (1) either the Company shall be the continuing corporation, or the
successor corporation shall be a corporation organized and existing under the
laws of the United States or a State thereof and such successor corporation
shall expressly assume the due and punctual payment of the principal of (and
premium or Make-Whole Amount, if any) and any interest on all of the Securities,
according to their tenor, and the due and punctual performance and observance of
all of the covenants and conditions of this Indenture to be performed by the
Company by supplemental indenture, complying with Article Nine hereof,
satisfactory to the Trustee, executed and delivered to the Trustee by such
corporation and (2) immediately after giving effect to such transaction and
treating any indebtedness which becomes an obligation of the Company or any
Subsidiary as a result thereof as having been incurred by the Company or such
Subsidiary at the time of such transaction, no Event of Default, and no event
which, after notice or the lapse of time, or both, would become an Event of
Default, shall have occurred and be continuing.


                                       58
<PAGE>   65
         SECTION 802. Rights and Duties of Successor Corporation. In case of any
such consolidation, merger, sale, lease or conveyance and upon any such
assumption by the successor corporation, such successor corporation shall
succeed to and be substituted for the Company, with the same effect as if it had
been named herein as the party of the first part, and the predecessor
corporation, except in the event of a lease, shall be relieved of any further
obligation under this Indenture and the Securities. Such successor corporation
thereupon may cause to be signed, and may issue either in its own name or in the
name of the Company, any or all of the Securities issuable hereunder which
theretofore shall not have been signed by the Company and delivered to the
Trustee; and, upon the order of such successor corporation, instead of the
Company, and subject to all the terms, conditions and limitations in this
Indenture prescribed, the Trustee shall authenticate and shall deliver any
Securities which previously shall have been signed and delivered by the officers
of the Company to the Trustee for authentication, and any Securities which such
successor corporation thereafter shall cause to be signed and delivered to the
Trustee for that purpose. All the Securities so issued shall in all respects
have the same legal rank and benefit under this Indenture as the Securities
theretofore or thereafter issued in accordance with the terms of this Indenture
as though all of such Securities had been issued at the date of the execution
hereof.

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

         SECTION 803. Officers' Certificate and Opinion of Counsel. Any
consolidation, merger, sale, lease or conveyance permitted under Section 801 is
also subject to the condition that the Trustee receive an Officers' Certificate
and an Opinion of Counsel to the effect that any such consolidation, merger,
sale, lease or conveyance, and the assumption by any successor corporation,
complies with the provisions of this Article and that all conditions precedent
herein provided for relating to such transaction have been complied with.


                     ARTICLE NINE - SUPPLEMENTAL INDENTURES

         SECTION 901. Supplemental Indentures Without Consent of Holders.
Without the consent of any Holders of Securities or coupons, the Company, when
authorized by or pursuant to a Board Resolution, and the Trustee, at any time
and from time to time, may enter into one or more indentures supplemental
hereto, in form satisfactory to the Trustee, for any of the following purposes:

                           (1) to evidence the succession of another Person to
         the Company and the assumption by any such successor of the covenants
         of the Company contained herein and in the Securities; or

<PAGE>   66
                           (2) to add to the covenants of the Company for the
         benefit of the Holders of all or any series of Securities (and if such
         covenants are to be for the benefit of less than all series of
         Securities, stating that such covenants are expressly being included
         solely for the benefit of such series) or to surrender any right or
         power herein conferred upon the Company; or

                           (3) to add any additional Events of Default for the
         benefit of the Holders of all or any series of Securities (and if such
         Events of Default are to be for the benefit of less than all series of
         Securities, stating that such Events of Default are expressly being
         included solely for the benefit of such series); provided, however,
         that in respect of any such additional Events of Default such
         supplemental indenture may provide for a particular period of grace
         after default (which period may be shorter or longer than that allowed
         in the case of other defaults) or may provide for an immediate
         enforcement upon such default or may limit the remedies available to
         the Trustee upon such default or may limit the right of the Holders of
         a majority in aggregate principal amount of that or those series of
         Securities to which such additional Events of Default apply to waive
         such default; or

                           (4) to add to or change any of the provisions of this
         Indenture to provide that Bearer Securities may be registrable as to
         principal, to change or eliminate any restrictions on the payment of
         principal of or premium or Make-Whole Amount, if any, or interest on
         Bearer Securities, to permit Bearer Securities to be issued in exchange
         for Registered Securities, to permit Bearer Securities to be issued in
         exchange for Bearer Securities of other authorized denominations or to
         permit or facilitate the issuance of Securities in uncertificated form,
         provided that any such action shall not adversely affect the interests
         of the Holders of Securities of any series or any related coupons in
         any material respect; or

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

                           (6) to secure the Securities; or

                           (7) to establish the form or terms of Securities of
         any series and any related coupons as permitted by Sections 201 and
         301; or

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

<PAGE>   67
                           (9) to cure any ambiguity, to correct or supplement
         any provision herein which may be defective or inconsistent with any
         other provision herein, or to make any other provisions with respect to
         matters or questions arising under this Indenture which shall not be
         inconsistent with the provisions of this Indenture, provided such
         provisions shall not adversely affect the interests of the Holders of
         Securities of any series or any related coupons in any material
         respect; or

                           (10) to supplement any of the provisions of this
         Indenture to such extent as shall be necessary to permit or facilitate
         the defeasance and discharge of any series of Securities pursuant to
         Sections 401, 1402 and 1403; provided that any such action shall not
         adversely affect the interests of the Holders of Securities of such
         series and any related coupons or any other series of Securities in any
         material respect.

         SECTION 902. Supplemental Indentures with Consent of Holders. With the
consent of the Holders of not less than a majority in principal amount of all
Outstanding Securities affected by such supplemental indenture, by Act of said
Holders delivered to the Company and the Trustee, the Company, when authorized
by or pursuant to a Board Resolution, and the Trustee may enter into an
indenture or indentures supplemental hereto for the purpose of adding any
provisions to or changing in any manner or eliminating any of the provisions of
this Indenture or of modifying in any manner the rights of the Holders of
Securities and any related coupons under this Indenture; provided, however, that
no such supplemental indenture shall, without the consent of the Holder of each
Outstanding Security affected thereby:

                           (1) change the Stated Maturity of the principal of
         (or premium or Make-Whole Amount, if any, on) or any installment of
         principal of or interest on, any Security; or reduce the principal
         amount thereof or the rate or amount of interest thereon, or any
         premium or Make-Whole Amount payable upon the redemption thereof, or
         reduce the amount of the principal of an Original Issue Discount
         Security that would be due and payable upon a declaration of
         acceleration of the Maturity thereof pursuant to Section 502 or the
         amount thereof provable in bankruptcy pursuant to Section 504, or

         in which, any Security or any premium or Make-Whole Amount or the
         interest thereon is payable, or impair the right to institute suit for
         the enforcement of any such payment on or after the Stated Maturity
         thereof (or, in the case of redemption or repayment at the option of
         the Holder, on or after the Redemption Date or the Repayment Date, as
         the case may be), or

                           (2) reduce the percentage in principal amount of the
         Outstanding Securities of any series, the consent of whose Holders is
         required for any such supplemental indenture, or the consent of whose
         Holders is required for any waiver with respect to such series (or
         compliance with certain provisions of this Indenture or


                                       61
<PAGE>   68
         certain defaults hereunder and their consequences) provided for in this
         Indenture, or reduce the requirements of Section 1504 for quorum or
         voting, or

                           (3) modify any of the provisions of this Section,
         Section 513 or Section 1009, except to increase the required percentage
         to effect such action or to provide that certain other provisions of
         this Indenture cannot be modified or waived without the consent of the
         Holder of each Outstanding Security affected thereby, provided,
         however, that this clause shall not be deemed to require the consent of
         any Holder with respect to changes in the references to "the Trustee"
         and concomitant changes in this Section 902 and Section 1009, or the
         deletion of this proviso, in accordance with the requirements of
         Sections 609(b) and 901(11).

         It shall not be necessary for any Act of Holders under this Section 902
to approve the particular form of any proposed supplemental indenture, but it
shall be sufficient if such Act shall approve the substance thereof.

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

         SECTION 903. Execution of Supplemental Indentures. In executing, or
accepting the additional trusts created by, any supplemental indenture permitted
by this Article or the modification thereby of the trusts created by this
Indenture, the Trustee shall be entitled to receive, and shall be fully
protected in relying upon, an Opinion of Counsel stating that the execution of
such supplemental indenture is authorized or permitted by this Indenture. The
Trustee may, but shall not be obligated to, enter into any such supplemental
indenture which affects the Trustee's own rights, duties or immunities under
this Indenture or otherwise.

         SECTION 904. Effect of Supplemental Indentures. Upon the execution of
any supplemental indenture under this Article, this Indenture shall be modified
in accordance therewith, and such supplemental indenture shall form a part of
this Indenture for all purposes; and every Holder of Securities theretofore or
thereafter authenticated and delivered hereunder and of any coupon appertaining
thereto shall be bound thereby.

         SECTION 905. Conformity with Trust Indenture Act. Every supplemental
indenture executed pursuant to this Article shall conform to the requirements of
the Trust Indenture Act as then in effect.

         SECTION 906. Reference in Securities to Supplemental Indentures.
Securities of any series authenticated and delivered after the execution of any
supplemental indenture pursuant to this Article may, and shall, if required by
the Trustee, bear a notation in form approved by the


                                       62
<PAGE>   69
Trustee as to any matter provided for in such supplemental indenture. If the
Company shall so determine, new Securities of any series so modified as to
conform, in the opinion of the Trustee and the Company, to any such supplemental
indenture may be prepared and executed by the Company and authenticated and
delivered by the Trustee in exchange for Outstanding Securities of such series.


                             ARTICLE TEN - COVENANTS

         SECTION 1001. Payment of Principal, Premium or Make-Whole Amount, if
any; and Interest. The Company covenants and agrees for the benefit of the
Holders of each series of Securities that it will duly and punctually pay the
principal of (and premium or Make-Whole Amount, if any) and interest on the
Securities of that series in accordance with the terms of such series of
Securities, any coupons appertaining thereto and this Indenture. Unless
otherwise specified as contemplated by Section 301 with respect to any series of
Securities, any interest due on Bearer Securities on or before Maturity shall be
payable only upon presentation and surrender of the several coupons for such
interest installments as are evidenced thereby as they severally mature. Unless
otherwise specified with respect to Securities of any series pursuant to Section
301, at the option of the Company, all payments of principal may be paid by
check to the registered Holder of the Registered Security or other person
entitled thereto against surrender of such Security.

         SECTION 1002. Maintenance of Office or Agency. If Securities of a
series are issuable only as Registered Securities, the Company shall maintain in
each Place of Payment for any series of Securities an office or agency where
Securities of that series may be presented or surrendered for payment, where
Securities of that series may be surrendered for registration of transfer or
exchange and where notices and demands to or upon the Company in respect of the
Securities of that series and this Indenture may be served. If Securities of a
series are issuable as Bearer Securities, the Company will maintain: (A) in the
Borough of Manhattan, The City of New York, an office or agency where any
Registered Securities of that series may be presented or surrendered for
payment, where any Registered Securities of that series may be surrendered for
registration of transfer, where Securities of that series may be surrendered for
exchange, where notices and demands to or upon the Company in respect of the
Securities of that series and this Indenture may be served and where Bearer
Securities of that series and related coupons may be presented or surrendered
for payment in the circumstances described in the following paragraph (and not
otherwise); (B) subject to any laws or regulations applicable thereto, in a


                                       63
<PAGE>   70
Place of Payment for that series which is located outside the United States, an
office or agency where Securities of that series and related coupons may be
presented and surrendered for payment; provided, however, that if the Securities
of that series are listed on any stock exchange located outside the United
States and such stock exchange shall so require, the Company will maintain a
Paying Agent for the Securities of that series in any required city located
outside the United States, as the case may be, so long as the Securities of that
series are listed on such exchange; and (C) subject to any laws or regulations
applicable thereto, in a Place of Payment for that series located outside the
United States an office or agency where any Registered Securities of that series
may be surrendered for registration of transfer, where Securities of that series
may be surrendered for exchange and where notices and demands to or upon the
Company in respect of the Securities of that series and this Indenture may be
served. The Company will give prompt written notice to the Trustee of the
location, and any change in the location, of each such office or agency. If at
any time the Company shall fail to maintain any such required office or agency
or shall fail to furnish the Trustee with the address thereof, such
presentations, surrenders, notices and demands may be made or served at the
Corporate Trust Office of the Trustee, except that Bearer Securities of that
series and the related coupons may be presented and surrendered for payment at
the offices specified in the Security, in London, England, and the Company
hereby appoints the same as its agent to receive such respective presentations,
surrenders, notices and demands, and the Company hereby appoints the Trustee its
agent to receive all such presentations, surrenders, notices and demands.

         Unless otherwise specified with respect to any Securities pursuant to
Section 301, no payment of principal, premium or Make-Whole Amount or interest
on Bearer Securities shall be made at any office or agency of the Company in the
United States or by check mailed to any address in the United States or by
transfer to an account maintained with a bank located in the United States;
provided, however, that, if the Securities of a series are payable in Dollars,
payment of principal of and any premium or Make-Whole Amount and interest on any
Bearer Security shall be made at the office of the Company's Paying Agent in the
Borough of Manhattan, The City of New York, if (but only if) payment in Dollars
of the full amount of such principal, premium or Make-Whole Amount, or interest,
as the case may be, at all offices or agencies outside the United States
maintained for the purpose by the Company in accordance with this Indenture, is
illegal or effectively precluded by exchange controls or other similar
restrictions.

         The Company may from time to time designate one or more other offices
or agencies where the Securities of one or more series may be presented or
surrendered for any or all of such purposes, and may from time to time rescind
such designations; provided, however, that no such designation or rescission
shall in any manner relieve the Company of its obligation to maintain an office
or agency in accordance with the requirements set forth above for Securities of
any series for such purposes. The Company will give prompt written notice to the
Trustee of any such designation or rescission and of any change in the location
of any such other office or agency. Unless otherwise specified with respect to
any Securities pursuant to Section 301 with respect to a series of Securities,
the Company hereby designates as a Place of Payment for each series of
Securities the office or agency of the Company in the Borough of Manhattan, The
City of New York, and initially appoints the Trustee at its Corporate Trust
Office as Paying Agent in such city and as its agent to receive all such
presentations, surrenders, notices and demands.

         Unless otherwise specified with respect to any Securities pursuant to
Section 301, if and so long as the Securities of any series (i) are denominated
in a Foreign Currency or (ii) may be


                                       64
<PAGE>   71
payable in a Foreign Currency, or so long as it is required under any other
provision of the Indenture, then the Company will maintain with respect to each
such series of Securities, or as so required, at least one exchange rate agent.

         SECTION 1003. Money for Securities Payments to Be Held in Trust. If the
Company shall at any time act as its own Paying Agent with respect to any series
of any Securities and any related coupons, it will, on or before each due date
of the principal of (and premium or Make-Whole Amount, if any), or interest on
any of the Securities of that series, segregate and hold in trust for the
benefit of the Persons entitled thereto a sum in the currency or currencies,
currency unit or units or composite currency or currencies in which the
Securities of such series are payable (except as otherwise specified pursuant to
Section 301 for the Securities of such series) sufficient to pay the principal
(and premium or Make-Whole Amount, if any) or interest so becoming due until
such sums shall be paid to such Persons or otherwise disposed of as herein
provided, and will promptly notify the Trustee of its action or failure so to
act.

         Whenever the Company shall have one or more Paying Agents for any
series of Securities and any related coupons, it will, on or before each due
date of the principal of (and premium or Make-Whole Amount, if any), or interest
on any Securities of that series, deposit with a Paying Agent a sum (in the
currency or currencies, currency unit or units or composite currency or
currencies described in the preceding paragraph) sufficient to pay the principal
(and premium or Make-Whole Amount, if any) or interest so becoming due, such sum
to be held in trust for the benefit of the Persons entitled to such principal,
premium or Make-Whole Amount, if any, or interest and (unless such Paying Agent
is the Trustee) the Company will promptly notify the Trustee of its action or
failure so to act.

         The Company will cause each Paying Agent for any series of Securities
other than the Trustee to execute and deliver to the Trustee an instrument in
which such Paying Agent shall agree with the Trustee, subject to the provisions
of this Section, that such Paying Agent will

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

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

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


                                       65
<PAGE>   72
         The Company may at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture or for any other purpose, pay, or
by Company Order direct any Paying Agent to pay, to the Trustee all sums held in
trust by the Company or such Paying Agent, such sums to be held by the Trustee
upon the same trusts as those upon which such sums were held by the Company or
such Paying Agent; and, upon such payment by any Paying Agent to the Trustee,
such Paying Agent shall be released from all further liability with respect to
such sums.

         Except as otherwise provided in the Securities of any series, any money
deposited with the Trustee or any Paying Agent, or then held by the Company, in
trust for the payment of the principal of (and premium or Make-Whole Amount, if
any) or interest on any Security of any series and remaining unclaimed for two
years after such principal (and premium or Make-Whole Amount, if any) or
interest has become due and payable shall be paid to the Company upon Company
Request or (if then held by the Company) shall be discharged from such trust;
and the Holder of such Security shall thereafter, as an unsecured general
creditor, look only to the Company for payment of such principal of (and premium
or Make-Whole Amount, if any) or interest on any Security, without interest
thereon, and all liability of the Trustee or such Paying Agent with respect to
such trust money, and all liability of the Company as trustee thereof, shall
thereupon cease; provided, however, that the Trustee or such Paying Agent,
before being required to make any such repayment, may at the expense of the
Company cause to be published once, in an Authorized Newspaper, notice that such
money remains unclaimed and that, after a date specified therein, which shall
not be less than 30 days from the date of such publication, any unclaimed
balance of such money then remaining will be repaid to the Company.

         SECTION 1004. Existence. Subject to Article Eight, the Company will do
or cause to be done all things necessary to preserve and keep in full force and
effect its corporate existence, all material rights (by articles of
incorporation, by-laws and statute) and material franchises; provided, however,
that the Company shall not be required to preserve any such right or franchise
if the Board of Directors shall determine that the preservation thereof is no
longer desirable in the conduct of the business of the Company.

         SECTION 1005. Maintenance of Properties. The Company will cause all of
its material properties used or useful in the conduct of its business or the
business of any Subsidiary to be maintained and kept in good condition, repair
and working order and supplied with all necessary equipment and will cause to be
made all necessary repairs, renewals, replacements, betterments and improvements
thereof, all as in the judgment of the Company may be necessary so that the
business carried on in connection therewith may be properly and advantageously
conducted at all times; provided, however, that the Company and its Subsidiaries
shall not be prevented from selling or otherwise disposing of their properties
for value in the ordinary course of business.


                                       66
<PAGE>   73
         SECTION 1006. Insurance. The Company will cause each of its and its
Subsidiaries' insurable properties to be insured against loss or damage in an
amount deemed reasonable by the Board of Directors with insurers of recognized
responsibility.

         SECTION 1007. Payment of Taxes and Other Claims. The Company will pay
or discharge or cause to be paid or discharged, before the same shall become
delinquent, (1) all taxes, assessments and governmental charges levied or
imposed upon it or any Subsidiary or upon the income, profits or property of the
Company or any Subsidiary, and (2) all lawful claims for labor, materials and
supplies which, if unpaid, might by law become a lien upon the property of the
Company or any Subsidiary; provided, however, that the Company shall not be
required to pay or discharge or cause to be paid or discharged any such tax,
assessment, charge or claim whose amount, applicability or validity is being
contested in good faith by appropriate proceedings.

         SECTION 1008. Statement as to Compliance. The Company will deliver to
the Trustee, within 120 days after the end of each fiscal year, a brief
certificate from the principal executive officer, principal financial officer or
principal accounting officer as to his or her knowledge of the Company's
compliance with all conditions and covenants under this Indenture and, in the
event of any noncompliance, specifying such noncompliance and the nature and
status thereof. For purposes of this Section 1008, such compliance shall be
determined without regard to any period of grace or requirement of notice under
this Indenture.

         SECTION 1009. Waiver of Certain Covenants. The Company may omit in any
particular instance to comply with any term, provision or condition set forth in
Sections 1004 to 1008, inclusive, if before or after the time for such
compliance the Holders of at least a majority in principal amount of all
outstanding Securities of such series, by Act of such Holders, either waive such
compliance in such instance or generally waive compliance with such covenant or
condition, but no such waiver shall extend to or affect such covenant or
condition except to the extent so expressly waived, and, until such waiver shall
become effective, the obligations of the Company and the duties of the Trustee
in respect of any such term, provision or condition shall remain in full force
and effect.

                    ARTICLE ELEVEN - REDEMPTION OF SECURITIES

         SECTION 1101. Applicability of Article. Securities of any series which
are redeemable before their Stated Maturity shall be redeemable in accordance
with their terms and (except as otherwise specified as contemplated by Section
301 for Securities of any series) in accordance with this Article.

         SECTION 1102. Election to Redeem; Notice to Trustee. The election of
the Company to redeem any Securities shall be evidenced by or pursuant to a
Board Resolution. In case of any redemption at the election of the Company of
less than all of the Securities of any series,


                                       67
<PAGE>   74
the Company shall, at least 45 days prior to the giving of the notice of
redemption in Section 1104 (unless a shorter notice shall be satisfactory to the
Trustee), notify the Trustee of such Redemption Date and of the principal amount
of Securities of such series to be redeemed. In the case of any redemption of
Securities prior to the expiration of any restriction on such redemption
provided in the terms of such Securities or elsewhere in this Indenture, the
Company shall furnish the Trustee with an Officers' Certificate evidencing
compliance with such restriction.

         SECTION 1103. Selection by Trustee of Securities to Be Redeemed. If
less than all the Securities of any series issued on the same day with the same
terms are to be redeemed, the particular Securities to be redeemed shall be
selected not more than 60 days prior to the Redemption Date by the Trustee, from
the Outstanding Securities of such series issued on such date with the same
terms not previously called for redemption, by such method as the Trustee shall
deem fair and appropriate and which may provide for the selection for redemption
of portions (equal to the minimum authorized denomination for Securities of that
series or any integral multiple thereof) of the principal amount of Securities
of such series of a denomination larger than the minimum authorized denomination
for Securities of that series.

         The Trustee shall promptly notify the Company and the Security
Registrar (if other than itself) in writing of the Securities selected for
redemption and, in the case of any Securities selected for partial redemption,
the principal amount thereof to be redeemed.

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

         SECTION 1104. Notice of Redemption. Notice of redemption shall be given
in the manner provided in Section 106, not less than 30 days nor more than 60
days prior to the Redemption Date, unless a shorter period is specified by the
terms of such series established pursuant to Section 301, to each Holder of
Securities to be redeemed, but failure to give such notice in the manner herein
provided to the Holder of any Security designated for redemption as a whole or
in part, or any defect in the notice to any such Holder, shall not affect the
validity of the proceedings for the redemption of any other such Security or
portion thereof.

         Any notice that is mailed to the Holders of Registered Securities in
the manner herein provided shall be conclusively presumed to have been duly
given, whether or not the Holder receives the notice.

         All notices of redemption shall state:

                           (1) the Redemption Date,


                                       68
<PAGE>   75
                           (2) the Redemption Price, accrued interest to the
         Redemption Date payable as provided in Section 1106, if any,

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

                           (4) in case any Security is to be redeemed in part
         only, the notice which relates to such Security shall state that on and
         after the Redemption Date, upon surrender of such Security, the holder
         will receive, without a charge, a new Security or Securities of
         authorized denominations for the principal amount thereof remaining
         unredeemed,

                           (5) that on the Redemption Date the Redemption Price
         and accrued interest to the Redemption Date payable as provided in
         Section 1106, if any, will become due and payable upon each such
         Security, or the portion thereof, to be redeemed and, if applicable,
         that interest thereon shall cease to accrue on and after said date,

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

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

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

                           (9) if Bearer Securities of any series are to be
         redeemed and any Registered Securities of such series are not to be
         redeemed, and if such Bearer Securities may be exchanged for Registered
         Securities not subject to redemption on this Redemption Date pursuant
         to Section 305 or otherwise, the last date, as determined by the
         Company, on which such exchanges may be made, and

                           (10) the CUSIP number of such Security, if any.



                                       69
<PAGE>   76
         Notice of redemption of Securities to be redeemed at the election of
the Company shall be given by the Company or, at the Company's request, by the
Trustee in the name and at the expense of the Company.

         SECTION 1105. Deposit of Redemption Price. On or prior to any
Redemption Date, the Company shall deposit with the Trustee or with a Paying
Agent (or, if the Company is acting as its own Paying Agent, which it may not do
in the case of a sinking fund payment under Article Twelve, segregate and hold
in trust as provided in Section 1003) an amount of money in the currency or
currencies, currency unit or units or composite currency or currencies in which
the Securities of such series are payable (except as otherwise specified
pursuant to Section 301 for the Securities of such series) sufficient to pay on
the Redemption Date the Redemption Price of, and (except if the Redemption Date
shall be an Interest Payment Date) accrued interest on, all the Securities or
portions thereof which are to be redeemed on that date.

         SECTION 1106. Securities Payable on Redemption Date. Notice of
redemption having been given as aforesaid, the Securities so to be redeemed
shall, on the Redemption Date, become due and payable at the Redemption Price
therein specified in the currency or currencies, currency unit or units or
composite currency or currencies in which the Securities of such series are
payable (except as otherwise specified pursuant to Section 301 for the
Securities of such series) (together with accrued interest, if any, to the
Redemption Date), and from and after such date (unless the Company shall default
in the payment of the Redemption Price and accrued interest) such Securities
shall, if the same were interest-bearing, cease to bear interest and the coupons
for such interest appertaining to any Bearer Securities so to be redeemed,
except to the extent provided below, shall be void. Upon surrender of any such
Security for redemption in accordance with said notice, together with all
coupons, if any, appertaining thereto maturing after the Redemption Date, such
Security shall be paid by the Company at the Redemption Price, together with
accrued interest, if any, to the Redemption Date; provided, however, that
installments of interest on Bearer Securities whose Stated Maturity is on or
prior to the Redemption Date shall be payable only at an office or agency
located outside the United States (except as otherwise provided in Section 1002)
and, unless otherwise specified as contemplated by Section 301, only upon
presentation and surrender of coupons for such interest; and provided further
that installments of interest on Registered Securities whose Stated Maturity is
on or prior to the Redemption Date shall be payable to the Holders of such
Securities, or one or more Predecessor Securities, registered as such at the
close of business on the relevant Record Dates according to their terms and the
provisions of Section 307.

         If any Bearer Security surrendered for redemption shall not be
accompanied by all appurtenant coupons maturing after the Redemption Date, such
Security may be paid after deducting from the Redemption Price an amount equal
to the face amount of all such missing coupons, or the surrender of such missing
coupon or coupons may be waived by the Company and the Trustee if there be
furnished to them such security or indemnity as they may require to


                                       70
<PAGE>   77
save each of them and any Paying Agent harmless. If thereafter the Holder of
such Security shall surrender to the Trustee or any Paying Agent any such
missing coupon in respect of which a deduction shall have been made from the
Redemption Price, such Holder shall be entitled to receive the amount so
deducted; provided, however, that interest represented by coupons shall be
payable only at an office or agency located outside the United States (except as
otherwise provided in Section 1002) and, unless otherwise specified as
contemplated by Section 301, only upon presentation and surrender of those
coupons.

         If any Security called for redemption shall not be so paid upon
surrender thereof for redemption, the principal (and premium or Make-Whole
Amount, if any) shall, until paid, bear interest from the Redemption Date at the
rate borne by the Security.

         SECTION 1107. Securities Redeemed in Part. Any Registered Security
which is to be redeemed only in part (pursuant to the provisions of this Article
or of Article Twelve) shall be surrendered at a Place of Payment therefor (with,
if the Company or the Trustee so requires, due endorsement by, or a written
instrument of transfer in form satisfactory to the Company and the Trustee duly
executed by, the Holder thereof or his attorney duly authorized in writing) and
the Company shall execute and the Trustee shall authenticate and deliver to the
Holder of such Security without service charge a new Security or Securities of
the same series, of any authorized denomination as requested by such Holder in
aggregate principal amount equal to and in exchange for the unredeemed portion
of the principal of the Security so surrendered. If a Global Security is so
surrendered, the Company shall execute and the Trustee shall authenticate and
deliver to the depository, without service charge, a new Global Security in a
denomination equal to and in exchange for the unredeemed portion of the
principal of the Global Security so surrendered.


                         ARTICLE TWELVE - SINKING FUNDS

         SECTION 1201. Applicability of Article. The provisions of this Article
shall be applicable to any sinking fund for the retirement of Securities of a
series except as otherwise specified as contemplated by Section 301 for
Securities of such series.

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


                                       71
<PAGE>   78
         SECTION 1202. Satisfaction of Sinking Fund Payments with Securities.
The Company may, in satisfaction of all or any part of any mandatory sinking
fund payment with respect to the Securities of a series, (1) deliver Outstanding
Securities of such series (other than any previously called for redemption)
together in the case of any Bearer Securities of such series with all unmatured
coupons appertaining thereto and (2) apply as a credit Securities of such series
which have been redeemed either at the election of the Company pursuant to the
terms of such Securities or through the application of permitted optional
sinking fund payments pursuant to the terms of such Securities, as provided for
by the terms of such Securities, or which have otherwise been acquired by the
Company; provided that such Securities so delivered or applied as a credit have
not been previously so credited. Such Securities shall be received and credited
for such purpose by the Trustee at the applicable Redemption Price specified in
such Securities for redemption through operation of the sinking fund and the
amount of such mandatory sinking fund payment shall be reduced accordingly.

         SECTION 1203. Redemption of Securities for Sinking Fund. Not less than
60 days prior to each sinking fund payment date for Securities of any series,
the Company will deliver to the Trustee an Officers' Certificate specifying the
amount of the next ensuing mandatory sinking fund payment for that series
pursuant to the terms of that series, the portion thereof, if any, which is to
be satisfied by payment of cash in the currency or currencies, currency unit or
units or composite currency or currencies in which the Securities of such series
are payable (except as otherwise specified pursuant to Section 301 for the
Securities of such series) and the portion thereof, if any, which is to be
satisfied by delivering and crediting Securities of that series pursuant to
Section 1202, and the optional amount, if any, to be added in cash to the next
ensuing mandatory sinking fund payment, and will also deliver to the Trustee any
Securities to be so delivered and credited. If such Officers' Certificate shall
specify an optional amount to be added in cash to the next ensuing mandatory
sinking fund payment, the Company shall thereupon be obligated to pay the amount
therein specified. Not less than 30 days before each such sinking fund payment
date the Trustee shall select the Securities to be redeemed upon such sinking
fund payment date in the manner specified in Section 1103 and cause notice of
the redemption thereof to be given in the name of and at the expense of the
Company in the manner provided in Section 1104. Such notice having been duly
given, the redemption of such Securities shall be made upon the terms and in the
manner stated in Sections 1106 and 1107.


              ARTICLE THIRTEEN - REPAYMENT AT THE OPTION OF HOLDERS

         SECTION 1301. Applicability of Article. Repayment of Securities of any
series before their Stated Maturity at the option of Holders thereof shall be
made in accordance with the terms of such Securities, if any, and (except as
otherwise specified by the terms of such series established pursuant to Section
301) in accordance with this Article.

                                       72
<PAGE>   79
         SECTION 1302. Repayment of Securities. Securities of any series subject
to repayment in whole or in part at the option of the Holders thereof will,
unless otherwise provided in the terms of such Securities, be repaid at a price
equal to the principal amount thereof, together with interest, if any, thereon
accrued to the Repayment Date specified in or pursuant to the terms of such
Securities. The Company covenants that on or prior to the Repayment Date it will
deposit with the Trustee or with a Paying Agent (or, if the Company is acting as
its own Paying Agent, segregate and hold in trust as provided in Section 1003)
an amount of money in the currency or currencies, currency unit or units or
composite currency or currencies in which the Securities of such series are
payable (except as otherwise specified pursuant to Section 301 for the
Securities of such series) sufficient to pay the principal (or, if so provided
by the terms of the Securities of any series, a percentage of the principal) of,
and (except if the Repayment Date shall be an Interest Payment Date) accrued
interest on, all the Securities or portions thereof, as the case may be, to be
repaid on such date.

         SECTION 1303. Exercise of Option. Securities of any series subject to
repayment at the option of the Holders thereof will contain an "Option to Elect
Repayment" form on the reverse of such Securities. In order for any Security to
be repaid at the option of the Holder, the Trustee must receive at the Place of
Payment therefor specified in the terms of such Security (or at such other place
or places of which the Company shall from time to time notify the Holders of
such Securities) not earlier than 60 days nor later than 30 days prior to the
Repayment Date (1) the Security so providing for such repayment together with
the "Option to Elect Repayment" form on the reverse thereof duly completed by
the Holder (or by the Holder's attorney duly authorized in writing) or (2) a
telegram, telex, facsimile transmission or a letter from a member of a national
securities exchange, or the National Association of Securities Dealers, Inc.
("NASD"), or a commercial bank or trust company in the United States setting
forth the name of the Holder of the Security, the principal amount of the
Security, the principal amount of the Security to be repaid, the CUSIP number,
if any, or a description of the tenor and terms of the Security, a statement
that the option to elect repayment is being exercised thereby and a guarantee
that the Security to be repaid, together with the duly completed form entitled
"Option to Elect Repayment" on the reverse of the Security, will be received by
the Trustee not later than the fifth Business Day after the date of such
telegram, telex, facsimile transmission or letter; provided, however, that such
telegram, telex, facsimile transmission or letter shall only be effective if
such Security and form duly completed are received by the Trustee by such fifth
Business Day. If less than the entire principal amount of such Security is to be
repaid in accordance with the terms of such Security, the principal amount of
such Security to be repaid, in increments of the minimum denomination for
Securities of such series, and the denomination or denominations of the Security
or Securities to be issued to the Holder for the portion of the principal amount
of such Security surrendered that is not to be repaid, must be specified. The
principal amount of any Security providing for repayment at the option of the
Holder thereof may not be repaid in part if, following such repayment, the
unpaid principal amount of such Security would be less than the minimum
authorized denomination of Securities of the series of which such Security to be
repaid is a part. Except as otherwise may be provided by the terms of any
Security providing


                                       73
<PAGE>   80
for repayment at the option of the Holder thereof, exercise of the repayment
option by the Holder shall be irrevocable unless waived by the Company.

         SECTION 1304. When Securities Presented for Repayment Become Due and
Payable. If Securities of any series providing for repayment at the option of
the Holders thereof shall have been surrendered as provided in this Article and
as provided by or pursuant to the terms of such Securities, such Securities or
the portions thereof, as the case may be, to be repaid shall become due and
payable and shall be paid by the Company on the Repayment Date therein
specified, and on and after such Repayment Date (unless the Company shall
default in the payment of such Securities on such Repayment Date) such
Securities shall, if the same were interest-bearing, cease to bear interest and
the coupons for such interest appertaining to any Bearer Securities so to be
repaid, except to the extent provided below, shall be void. Upon surrender of
any such Security for repayment in accordance with such provisions, together
with all coupons, if any, appertaining thereto maturing after the Repayment
Date, the principal amount of such Security so to be repaid shall be paid by the
Company, together with accrued interest, if any, to the Repayment Date;
provided, however, that coupons whose Stated Maturity is on or prior to the
Repayment Date shall be payable only at an office or agency located outside the
United States (except as otherwise provided in Section 1002) and, unless
otherwise specified pursuant to Section 301, only upon presentation and
surrender of such coupons; and provided further that, in the case of Registered
Securities, installments of interest, if any, whose Stated Maturity is on or
prior to the Repayment Date shall be payable (but without interest thereon,
unless the Company shall default in the payment thereof) to the Holders of such
Securities, or one or more Predecessor Securities, registered as such at the
close of business on the relevant Record Dates according to their terms and the
provisions of Section 307.

         If any Bearer Security surrendered for repayment shall not be
accompanied by all appurtenant coupons maturing after the Repayment Date, such
Security may be paid after deducting from the amount payable therefor as
provided in Section 1302 an amount equal to the face amount of all such missing
coupons, or the surrender of such missing coupon or coupons may be waived by the
Company and the Trustee if there be furnished to them such security or indemnity
as they may require to save each of them and any Paying Agent harmless. If
thereafter the Holder of such Security shall surrender to the Trustee or any
Paying Agent any such missing coupon in respect of which a deduction shall have
been made as provided in the preceding sentence, such Holder shall be entitled
to receive the amount so deducted; provided, however, that interest represented
by coupons shall be payable only at an office or agency located outside the
United States (except as otherwise provided in Section 1002) and, unless
otherwise specified as contemplated by Section 301, only upon presentation and
surrender of those coupons.

         If the principal amount of any Security surrendered for repayment shall
not be so repaid upon surrender thereof, such principal amount (together with
interest, if any, thereon accrued to such Repayment Date) shall, until paid,
bear interest from the Repayment Date at the rate of


                                       74
<PAGE>   81
interest or Yield to Maturity (in the case of Original Issue Discount
Securities) set forth in such Security.

         SECTION 1305. Securities Repaid in Part. Upon surrender of any
Registered Security which is to be repaid in part only, the Company shall
execute and the Trustee shall authenticate and deliver to the Holder of such
Security, without service charge and at the expense of the Company, a new
Registered Security or Securities of the same series, of any authorized
denomination specified by the Holder, in an aggregate principal amount equal to
and in exchange for the portion of the principal of such Security so surrendered
which is not to be repaid.


              ARTICLE FOURTEEN - DEFEASANCE AND COVENANT DEFEASANCE

         SECTION 1401. Applicability of Article: Company's Option to Effect
Defeasance or Covenant Defeasance. If, pursuant to Section 301, provision is
made for either or both of (a) defeasance of the Securities of or within a
series under Section 1402 or (b) covenant defeasance of the Securities of or
within a series under Section 1403, then the provisions of such Section or
Sections, as the case may be, together with the other provisions of this Article
(with such modifications thereto as may be specified pursuant to Section 301
with respect to any Securities), shall be applicable to such Securities and any
coupons appertaining thereto, and the Company may at its option by Board
Resolution, at any time, with respect to such Securities and any coupons
appertaining thereto, elect to have Section 1402 (if applicable) or Section 1403
(if applicable) be applied to such Outstanding Securities and any coupons
appertaining thereto upon compliance with the conditions set forth below in this
Article.

         SECTION 1402. Defeasance and Discharge. Upon the Company's exercise of
the above option applicable to this Section with respect to any Securities of or
within a series, the Company shall be deemed to have been discharged from its
obligations with respect to such Outstanding Securities and any coupons
appertaining thereto on the date the conditions set forth in Section 1404 are
satisfied (hereinafter, "defeasance"). For this purpose, such defeasance means
that the Company shall be deemed to have paid and discharged the entire
indebtedness represented by such Outstanding Securities and any coupons
appertaining thereto, which shall thereafter be deemed to be "Outstanding" only
for the purposes of Section 1405 and the other Sections of this Indenture
referred to in clauses (A) and (B) below, and to have satisfied all of its other
obligations under such Securities and any coupons appertaining thereto and this
Indenture insofar as such Securities and any coupons appertaining thereto are
concerned (and the Trustee, at the expense of the Company, shall execute proper
instruments acknowledging the same), except for the following which shall
survive until otherwise terminated or discharged hereunder: (A) the rights of
Holders of such Outstanding Securities and any coupons appertaining thereto to
receive, solely from the trust fund described in Section 1404 and as more fully
set forth in such Section, payments in respect of the principal of (and premium
or Make-Whole Amount, if any) and interest, if any, on such Securities and any


                                       75
<PAGE>   82
coupons appertaining thereto when such payments are due, (B) the Company's
obligations with respect to such Securities under Sections 305, 306, 1002 and
1003, (C) the rights, powers, trusts, duties and immunities of the Trustee
hereunder and (D) this Article. Subject to compliance with this Article
Fourteen, the Company may exercise its option under this Section notwithstanding
the prior exercise of its option under Section 1403 with respect to such
Securities and any coupons appertaining thereto.

         SECTION 1403. Covenant Defeasance. Upon the Company's exercise of the
above option applicable to this Section with respect to any Securities of or
within a series, the Company shall be released from its obligations under
Sections 1004 to 1009, inclusive, and, if specified pursuant to Section 301, its
obligations under any other covenant contained herein or in any indenture
supplemental hereto, with respect to such Outstanding Securities and any coupons
appertaining thereto on and after the date the conditions set forth in Section
1404 are satisfied (hereinafter, "covenant defeasance"), and such Securities and
any coupons appertaining thereto shall thereafter be deemed to be not
"Outstanding" for the purposes of any direction, waiver, consent or declaration
or Act of Holders (and the consequences of any thereof) in connection with
Sections 1004 to 1009, inclusive, or such other covenant, but shall continue to
be deemed "Outstanding" for all other purposes hereunder. For this purpose, such
covenant defeasance means that, with respect to such Outstanding Securities and
any coupons appertaining thereto, the Company may omit to comply with and shall
have no liability in respect of any term, condition or limitation set forth in
any such Section or such other covenant, whether directly or indirectly, by
reason of any reference elsewhere herein to any such Section or such other
covenant or by reason of reference in any such Section or such other covenant to
any other provision herein or in any other document and such omission to comply
shall not constitute a default or an Event of Default under Section 501(4) or
501(8) or otherwise, as the case may be, but, except as specified above, the
remainder of this Indenture and such Securities and any coupons appertaining
thereto shall be unaffected thereby.

         SECTION 1404. Conditions to Defeasance or Covenant Defeasance. The
following shall be the conditions to application of Section 1402 or Section 1403
to any Outstanding Securities of or within a series and any coupons appertaining
thereto:

                  (a) The Company shall irrevocably have deposited or caused to
be deposited with the Trustee (or another trustee satisfying the requirements of
Section 607 who shall agree to comply with the provisions of this Article
Fourteen applicable to it) as trust funds in trust for the purpose of making the
following payments, specifically pledged as security for, and dedicated solely
to, the benefit of the Holders of such Securities and any coupons appertaining
thereto, (1) an amount in such currency, currencies or currency unit in which
such Securities and any coupons appertaining thereto are then specified as
payable at Stated Maturity, or (2) Government Obligations applicable to such
Securities and coupons appertaining thereto (determined on the basis of the
currency, currencies or currency unit in which such Securities and coupons
appertaining thereto are then specified as payable at Stated Maturity) which
through the scheduled payment of principal and interest in respect thereof in
accordance with


                                       76
<PAGE>   83
their terms will provide, not later than the due date of any payment of
principal of (and premium or Make-Whole Amount, if any) and interest, if any, on
such Securities and any coupons appertaining thereto, money in an amount, or (3)
a combination thereof, in any case, in an amount, sufficient, without
consideration of any reinvestment of such principal and interest, in the opinion
of a nationally recognized firm of independent public accountants expressed in a
written certification thereof delivered to the Trustee, to pay and discharge,
and which shall be applied by the Trustee (or other qualifying trustee) to pay
and discharge, (i) the principal of (and premium or Make-Whole Amount, if any)
and interest, if any, on such Outstanding Securities and any coupons
appertaining thereto on the Stated Maturity of such principal or installment of
principal or interest and (ii) any mandatory sinking fund payments or analogous
payments applicable to such Outstanding Securities and any coupons appertaining
thereto on the day on which such payments are due and payable in accordance with
the terms of this Indenture and of such Securities and any coupons appertaining
thereto.

                  (b) Such defeasance or covenant defeasance shall not result in
a breach or violation of, or constitute a default under, this Indenture or any
other material agreement or instrument to which the Company is a party or by
which it is bound.

                  (c) No Event of Default or event which with notice or lapse of
time or both would become an Event of Default with respect to such Securities
and any coupons appertaining thereto shall have occurred and be continuing on
the date of such deposit or, insofar as Sections 501(6) and 501(7) are
concerned, at any time during the period ending on the 91st day after the date
of such deposit (it being understood that this condition shall not be deemed
satisfied until the expiration of such period).

                  (d) In the case of an election under Section 1402, the Company
shall have delivered to the Trustee an Opinion of Counsel stating that (i) the
Company has received from, or there has been published by, the Internal Revenue
Service a ruling, or (ii) since the date of execution of this Indenture, there
has been a change in the applicable Federal income tax law, in either case to
the effect that, and based thereon such opinion shall confirm that, the Holders
of such Outstanding Securities and any coupons appertaining thereto will not
recognize income, gain or loss for Federal income tax purposes as a result of
such defeasance and will be subject to Federal income tax on the same amounts,
in the same manner and at the same times as would have been the case if such
defeasance had not occurred.

                  (e) In the case of an election under Section 1403, the Company
shall have delivered to the Trustee an Opinion of Counsel to the effect that the
Holders of such Outstanding Securities and any coupons appertaining thereto will
not recognize income, gain or loss for Federal income tax purposes as a result
of such covenant defeasance and will be subject to Federal income tax on the
same amounts, in the same manner and at the same times as would have been the
case if such covenant defeasance had not occurred.


                                       77
<PAGE>   84
                  (f) The Company shall have delivered to the Trustee an
Officers' Certificate and an Opinion of Counsel, each stating that all
conditions precedent to the defeasance under Section 1402 or the covenant
defeasance under Section 1403 (as the case may be) have been complied with and
an Opinion of Counsel to the effect that either (i) as a result of a deposit
pursuant to subsection (a) above and the related exercise of the Company's
option under Section 1402 or Section 1403 (as the case may be), registration is
not required under the Investment Company Act of 1940, as amended, by the
Company, with respect to the trust funds representing such deposit or by the
Trustee for such trust funds or (ii) all necessary registrations under said Act
have been effected.

                  (g) Notwithstanding any other provisions of this Section, such
defeasance or covenant defeasance shall be effected in compliance with any
additional or substitute terms, conditions or limitations which may be imposed
on the Company in connection therewith pursuant to Section 301.

         SECTION 1405. Deposited Money and Government Obligations to Be Held in
Trust; Other Miscellaneous Provisions. Subject to the provisions of the last
paragraph of Section 1003, all money and Government Obligations (or other
property as may be provided pursuant to Section 301) (including the proceeds
thereof) deposited with the Trustee (or other qualifying trustee, collectively
for purposes of this Section 1405, the "Trustee") pursuant to Section 1404 in
respect of any Outstanding Securities of any series and any coupons appertaining
thereto shall be held in trust and applied by the Trustee, in accordance with
the provisions of such Securities and any coupons appertaining thereto and this
Indenture, to the payment, either directly or through any Paying Agent
(including the Company acting as its own Paying Agent) as the Trustee may
determine, to the Holders of such Securities and any coupons appertaining
thereto of all sums due and to become due thereon in respect of principal (and
premium or Make-Whole Amount, if any) and interest, but such money need not be
segregated from other funds except to the extent required by law.

         Unless otherwise specified with respect to any Security pursuant to
Section 301, if, after a deposit referred to in Section 1404(a) has been made,
(a) the Holder of a Security in respect of which such deposit was made is
entitled to, and does, elect pursuant to Section 301 or the terms of such
Security to receive payment in a currency or currency unit other than that in
which the deposit pursuant to Section 1404(a) has been made in respect of such
Security, or (b) a Conversion Event occurs in respect of the currency or
currency unit in which the deposit pursuant to Section 1404(a) has been made,
the indebtedness represented by such Security and any coupons appertaining
thereto shall be deemed to have been, and will be, fully discharged and
satisfied through the payment of the principal of (and premium or Make-Whole
Amount, if any), and interest, if any, on such Security as the same becomes due
out of the proceeds yielded by converting (from time to time as specified below
in the case of any such election) the amount or other property deposited in
respect of such Security into the currency or currency unit in which such
Security becomes payable as a result of such election or Conversion Event based
on the applicable market exchange rate for such currency or currency


                                       78
<PAGE>   85
unit in effect on the second Business Day prior to each payment date, except,
with respect to a Conversion Event, for such currency or currency unit in effect
(as nearly as feasible) at the time of the Conversion Event.

         The Company shall pay and indemnify the Trustee against any tax, fee or
other charge imposed on or assessed against the Government Obligations deposited
pursuant to Section 1404 or the principal and interest received in respect
thereof other than any such tax, fee or other charge which by law is for the
account of the Holders of such Outstanding Securities and any coupons
appertaining thereto.

         Anything in this Article to the contrary notwithstanding, subject to
Section 606, the Trustee shall deliver or pay to the Company from time to time
upon Company Request any money or Government Obligations (or other property and
any proceeds therefrom) held by it as provided in Section 1404 which, in the
opinion of a nationally recognized firm of independent public accountants
expressed in a written certification thereof delivered to the Trustee, are in
excess of the amount thereof which would then be required to be deposited to
effect a defeasance or covenant defeasance, as applicable, in accordance with
this Article.

         SECTION 1501. Purposes for Which Meetings May Be Called. A meeting of

proposed to be taken at the meeting, and the Trustee shall not have made the

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

         Notwithstanding the foregoing provisions of this Section 1504, if any
action is to be taken at a meeting of Holders of Securities of any series with
respect to any request, demand, authorization, direction, notice, consent,
waiver or other action that this Indenture expressly provides may be made, given
or taken by the Holders of a specified percentage in principal amount of all
Outstanding Securities affected thereby, or of the Holders of such series and
one or more additional series:

                           (i) there shall be no minimum quorum requirement for
         such meeting; and

                           (ii) the principal amount of the Outstanding
         Securities of such series that vote in favor of such request, demand,
         authorization, direction, notice, consent, waiver or other action shall
         be taken into account in determining whether such request, demand,
         authorization, direction, notice, consent, waiver or other action has
         been made, given or taken under this Indenture.

         SECTION 1505. Determination of Voting Rights; Conduct and Adjournment
of Meetings. (a) Notwithstanding any provisions of this Indenture, the Trustee
may make such reasonable regulations as it may deem advisable for any meeting of
Holders of Securities of a series in regard to proof of the holding of
Securities of such series and of the appointment of proxies and in regard to the
appointment and duties of inspectors of votes, the submission and examination of
proxies, certificates and other evidence of the right to vote, and such other
matters concerning the conduct of the meeting as it shall deem appropriate.
Except as otherwise permitted or required by any such regulations, the holding
of Securities shall be proved in the manner specified in Section 104 and the
appointment of any proxy shall be proved in the manner specified in Section 104
or by having the signature of the Person executing the proxy witnessed or
guaranteed by any trust company, bank or banker authorized by Section 104 to
certify to the holding of Bearer Securities. Such regulations may provide that
written instruments appointing proxies, regular on their face, may be presumed
valid and genuine without the proof specified in Section 104 or other proof.

                  (b) The Trustee shall, by an instrument in writing appoint a
temporary chairman of the meeting, unless the meeting shall have been called by
the Company or by Holders of Securities as provided in Section 1502(b), in which
case the Company or the Holders of Securities of the series calling the meeting,
as the case may be, shall in like manner appoint a temporary chairman. A
permanent chairman and a permanent secretary of the meeting shall be elected by
vote of the Persons entitled to vote a majority in principal amount of the
Outstanding Securities of such series represented at the meeting.

<PAGE>   88
                  (c) At any meeting each Holder of a Security of such series or
proxy shall be entitled to one vote for each $1,000 principal amount of the
Outstanding Securities of such series held or represented by him; provided,
however, that no vote shall be cast or counted at any meeting in respect of any
Security challenged as not Outstanding and ruled by the chairman of the meeting
to be not Outstanding. The chairman of the meeting shall have no right to vote,
except as a Holder of a Security of such series or proxy.

                  (d) Any meeting of Holders of Securities of any series duly
called pursuant to Section 1502 at which a quorum is present may be adjourned
from time to time by Persons entitled to vote a majority in principal amount of
the Outstanding Securities of such series represented at the meeting, and the
meeting may be held as so adjourned without further notice.

         SECTION 1506. Counting Votes and Recording Action of Meetings. The vote
upon any resolution submitted to any meeting of Holders of Securities of any
series shall be by written ballots on which shall be subscribed the signatures
of the Holders of Securities of such series or of their representatives by proxy
and the principal amounts and serial numbers of the Outstanding Securities of
such series held or represented by them. The permanent chairman of the meeting
shall appoint two inspectors of votes who shall count all votes cast at the
meeting for or against any resolution and who shall make and file with the
secretary of the meeting their verified written reports in duplicate of all
votes cast at the meeting. A record, at least in duplicate, of the proceedings
of each meeting of Holders of Securities of any Series shall be prepared by the
secretary of the meeting and there shall be attached to said record the original
reports of the inspectors of votes on any vote by ballot taken thereat and
affidavits by one or more persons having knowledge of the fact, setting forth a
copy of the notice of the meeting and showing that said notice was given as
provided in Section 1502 and, if applicable, Section 1504. Each copy shall be
signed and verified by the affidavits of the permanent chairman and secretary of
the meeting and one such copy shall be delivered to the Company and another to
the Trustee to be preserved by the Trustee, the latter to have attached thereto
the ballots voted at the meeting. Any record so signed and verified shall be
conclusive evidence of the matters therein stated.

BAY APARTMENT COMMUNITIES, INC., a Maryland corporation (herein referred to as

registered at the close of business on a Special Record Date for the payment of
such Defaulted Interest to be fixed by the Trustee, notice whereof shall be
given to Holders of Securities of this series not less than 10 days prior to

principal of this Security shall not bear interest except in the case of a
default in payment of principal upon acceleration, upon redemption or at the

or duly provided for. Interest on any overdue principal shall be payable on
demand. Any such interest on any overdue principal that is not so paid on demand
shall bear interest at the rate of % per annum (to the extent that the payment
of such interest shall be legally enforceable), which shall accrue from the date
of such demand for payment to the date payment of such interest has been made or

the aggregate principal amount of the Outstanding Securities, on behalf of the
Holders of all such Securities, to waive compliance by the Company with certain
provisions of the Indenture. Furthermore, provisions in the Indenture permit the
Holders of not less than a majority of the aggregate principal amount, in
certain instances, of the Outstanding Securities of any series to waive, on
behalf of all of the Holders of Securities of such series, certain past defaults

registration of transfer hereof or in exchange herefor or in lieu hereof,
whether or not notation of such consent or waiver is made upon this Security.

on this Security are payable, 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 Securities, of authorized
denominations and for the same aggregate principal amount, will be issued to the
designated transferee or transferees.

         As provided in the Indenture and subject to certain limitations therein
[and herein] set forth, this Security is exchangeable for a like aggregate

otherwise having the same terms and conditions, as requested by the Holder
hereof surrendering the same.

         The Securities of this series are issuable only in registered form
[without coupons] in denominations of $_______ and any integral multiple
thereof.

         No service charge shall be made for any such registration of transfer

any tax or other governmental charge payable in connection therewith,

the Person in whose name this Security is registered as the owner hereof for all
purposes, whether or not this Security be overdue, and neither the Company, the
Trustee nor any such agent shall be affected by notice to the contrary.

         No recourse shall be had for the payment of the principal of or premium
or Make-Whole Amount, if any, or the interest on this Security, or for any claim
based hereon, or otherwise in respect hereof, or based on or in respect of the
Indenture or any indenture supplemental thereto, against any past, present or
future stockholder, employee, officer or director, as such, of the Company or of
any successor, either directly or through the Company or any successor, whether
by virtue of any constitution, statute or rule of law or by the enforcement of
any assessment or penalty or otherwise, all such liability being, by the
acceptance hereof and as part of the consideration for the issue hereof,
expressly waived and released.

         The Indenture and the Securities shall be governed by and construed in
accordance with the laws of [the State of New York] applicable to agreements
made and to be performed entirely in such State.

request by the Company to the Trustee to take any action under any provision of
this Indenture, the Company shall furnish to the Trustee an Officers'
Certificate stating that all conditions precedent, if any, provided for in this
Indenture relating to the proposed action have been complied with and an Opinion

      Every certificate or opinion with respect to compliance with a condition

                                       12
<PAGE>   20
            (2) a brief statement as to the nature and scope of the examination

            (3) a statement that, in the opinion of each such individual, he has

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

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

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

      SECTION 104. Acts of Holders. (a) Any request, demand, authorization,
direction, notice, consent, waiver or other action provided by this Indenture to
be given or taken by Holders of the Outstanding Securities of all series or one
or more series, as the case may be, may be embodied in and evidenced by one or
more instruments of substantially similar tenor signed by such Holders in person
or by agents duly appointed in writing. If Securities of a series are issuable
as Bearer Securities, any request, demand, authorization, direction, notice,
consent, waiver or other action provided by this Indenture to be given or taken
by Holders of Securities of such series may, alternatively, be embodied in and
evidenced by the record of Holders of Securities of such series voting in favor
thereof, either in person or by proxies duly appointed in writing, at any
meeting of Holders of Securities of such series duly called and


                                       13
<PAGE>   21
held in accordance with the provisions of Article Fifteen, or a combination of
such instruments and any such record. Except as herein otherwise expressly
provided, such action shall become effective when such instrument or instruments
or record or both are delivered to the Trustee and, where it is hereby expressly
required, to the Company. Such instrument or instruments and any such record
(and the action embodied therein and evidenced thereby) are herein sometimes
referred to as the "Act" of the Holders signing such instrument or instruments
or so voting at any such meeting. Proof of execution of any such instrument or
of a writing appointing any such agent, or of the holding by any Person of a
Security, shall be sufficient for any purpose of this Indenture and conclusive
in favor of the Trustee and the Company and any agent of the Trustee or the
Company, if made in the manner provided in this Section. The record of any
meeting of Holders of Securities shall be proved in the manner provided in
Section 1506.

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

            (c) The ownership of Registered Securities shall be proved by the
Security Register. As to any matter relating to beneficial ownership interests
in any Global Security, the appropriate depository's records shall be
dispositive for purposes of this Indenture.

            (d) The ownership of Bearer Securities may be proved by the
production of such Bearer Securities or by a certificate executed, as
depository, by any trust company, bank, banker or other depository, wherever
situated, if such certificate shall be deemed by the Trustee to be satisfactory,
showing that at the date therein mentioned such Person had on deposit with such
depository, or exhibited to it, the Bearer Securities therein described; or such
facts may be proved by the certificate or affidavit of the Person holding such
Bearer Securities, if such certificate or affidavit is deemed by the Trustee to
be satisfactory. The Trustee and the Company may assume that such ownership of
any Bearer Security continues until (1) another certificate or affidavit bearing
a later date issued in respect of the same Bearer Security is produced, or (2)
such Bearer Security is produced to the Trustee by some other Person, or (3)
such Bearer Security is surrendered in exchange for a Registered Security, or
(4) such Bearer Security is no longer Outstanding. The ownership of Bearer
Securities may also be proved in any other manner which the Trustee deems
sufficient.

            (e) If the Company shall solicit from the Holders of Registered
Securities any request, demand, authorization, direction, notice, consent,
waiver or other Act, the Company may, at its option, in or pursuant to a Board
Resolution, fix in advance a record date


                                       14
<PAGE>   22
for the determination of Holders entitled to give such request, demand,
authorization, direction, notice, consent, waiver or other Act, but the Company
shall have no obligation to do so. Notwithstanding TIA Section 316(c), such
record date shall be the record date specified in or pursuant to such Board
Resolution, which shall be a date not earlier than the date 30 days prior to the
first solicitation of Holders generally in connection therewith and not later
than the date such solicitation is completed. If such a record date is fixed,
such request, demand, authorization, direction, notice, consent, waiver or other
Act may be given before or after such record date, but only the Holders of
record at the close of business on such record date shall be deemed to be
Holders for the purposes of determining whether Holders of the requisite
proportion of Outstanding Securities have authorized or agreed or consented to
such request, demand, authorization, direction, notice, consent, waiver or other
Act, and for that purpose the Outstanding Securities shall be computed as of
such record date; provided that no such authorization, agreement or consent by
the Holders on such record date shall be deemed effective unless it shall become
effective pursuant to the provisions of this Indenture not later than eleven
months after the record date.

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

      SECTION 105. Notices, etc., to Trustee and Company. Any request, demand,
authorization, direction, notice, consent, waiver or Act of Holders or other
document provided or permitted by this Indenture to be made upon, given or
furnished to, or filed with,

                  (1) the Trustee by any Holder or by the Company shall be
      sufficient for every purpose hereunder if made, given, furnished or filed
      in writing to or with the Trustee at [__________________________]; or

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

                  (3) either the Trustee or the Company, by the other party,
      shall be sufficient for every purpose hereunder if given by facsimile
      transmission, receipt confirmed by telephone followed by an original copy
      delivered by guaranteed overnight courier; if to the Trustee at facsimile
      number [_________________]; and if to the Company at facsimile number
      (408) 554-9780.

<PAGE>   23
      SECTION 106. Notice to Holders: Waiver. Where this Indenture provides for
notice of any event to Holders of Registered Securities by the Company or the
Trustee, such notice shall be sufficiently given (unless otherwise herein
expressly provided) if in writing and mailed, first-class postage prepaid, to
each such Holder affected by such event, at his address as it appears in the
Security Register, not later than the latest date, if any, and not earlier than
the earliest date, if any, prescribed for the giving of such notice. In any case
where notice to Holders of Registered Securities is given by mail, neither the
failure to mail such notice, nor any defect in any notice so mailed, to any
particular Holder shall affect the sufficiency of such notice with respect to
other Holders of Registered Securities or the sufficiency of any notice to
Holders of Bearer Securities given as provided herein. Any notice mailed to a
Holder in the manner herein prescribed shall be conclusively deemed to have been
received by such Holder, whether or not such Holder actually receives such
notice.

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

      Except as otherwise expressly provided herein or otherwise specified with
respect to any Securities pursuant to Section 301, where this Indenture provides
for notice to Holders of Bearer Securities of any event, such notice shall be
sufficiently given if published in an Authorized Newspaper in The City of New
York and in such other city or cities as may be specified in such Securities on
a Business Day, such publication to be not later than the latest date, if any,
and not earlier than the earliest date, if any, prescribed for the giving of
such notice. Any such notice shall be deemed to have been given on the date of
such publication or, if published more than once, on the date of the first such
publication.

      If by reason of the suspension of publication of any Authorized Newspaper
or Authorized Newspapers or by reason of any other cause it shall be
impracticable to publish any notice to Holders of Bearer Securities as provided
above, then such notification to Holders of Bearer Securities as shall be given
with the approval of the Trustee shall constitute sufficient notice to such
Holders for every purpose hereunder. Neither the failure to give notice by
publication to any particular Holder of Bearer Securities as provided above, nor
any defect in any notice so published, shall affect the sufficiency of such
notice with respect to other Holders of Bearer Securities or the sufficiency of
any notice to Holders of Registered Securities given as provided herein.

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

      Where this Indenture provides for notice in any manner, such notice may be
waived in writing by the Person entitled to receive such notice, either before
or after the event, and such waiver shall be the equivalent of such notice.
Waivers of notice by Holders shall be filed with


                                       16
<PAGE>   24
the Trustee, but such filing shall not be a condition precedent to the validity
of any action taken in reliance upon such waiver.

      SECTION 107. Counterparts; Effect of Headings and Table of Contents. This
Indenture may be executed in any number of counterparts, each of which so
executed shall be deemed to be an original, but all such counterparts shall
together constitute but one and the same Indenture. The Article and Section
headings herein and the Table of Contents are for convenience only and shall not
affect the construction hereof.

      SECTION 108. Successors and Assigns. All covenants and agreements in this
Indenture by the Company shall bind its successors and assigns, whether so
expressed or not.

      SECTION 109. Severability Clause. In case any provision in this Indenture
or in any Security or coupon shall be held invalid, illegal or unenforceable,
the validity, legality and enforceability of the remaining provisions shall not
in any way be affected or impaired thereby.

      SECTION 110. Benefits of Indenture. Nothing in this Indenture or in the
Securities or coupons, express or implied, shall give to any Person, other than
the parties hereto, any Security Registrar, any Paying Agent, any Authenticating
Agent and their successors hereunder and the Holders any benefit or any legal or
equitable right, remedy or claim under this Indenture.

      SECTION 111. Governing Law. This Indenture and the Securities and coupons
shall be governed by and construed in accordance with the law of the State of
New York. This Indenture is subject to the provisions of the TIA that are
required to be part of this Indenture and shall, to the extent applicable, be
governed by such provisions.

      SECTION 112. Legal Holidays. In any case where any Interest Payment Date,
Redemption Date, Repayment Date, sinking fund payment date, Stated Maturity or
Maturity of any Security or the last date on which a Holder has the right to
convert or exchange a Security shall not be a Business Day at any Place of
Payment, then (notwithstanding any other provision of this Indenture or any
Security or coupon other than a provision in the Securities of any series which
specifically states that such provision shall apply in lieu hereof), payment of
interest or principal (and premium or Make-Whole Amount, if any) or conversion
or exchange of such security need not be made at such Place of Payment on such
date, but (except as otherwise provided in the supplemental indenture with
respect to such Security) may be made on the next succeeding Business Day at
such Place of Payment with the same force and effect as if made on the Interest
Payment Date, Redemption Date, Repayment Date or sinking fund payment date, or
at the Stated Maturity or Maturity, or on such last day for conversion or
exchange, provided that no interest shall accrue on the amount so payable for
the period from and after such Interest Payment Date, Redemption Date, Repayment
Date, sinking fund payment date, Stated Maturity or Maturity, as the case may
be.


                                       17
<PAGE>   25
      SECTION 113. Immunity of Stockholders, Directors, Officers and Agents of
the Company. No recourse under or upon any obligation, covenant or agreement
contained in this Indenture, or in any Security, or because of any indebtedness
evidenced thereby, shall be had against any past, present or future stockholder,
employee, officer or director, as such, of the Company or of any successor,
either directly or through the Company or any successor, under any rule of law,
statute or constitutional provision or by the enforcement of any assessment or
by any legal or equitable proceeding or otherwise, all such liability being
expressly waived and released by the acceptance of the Securities by the Holders
and as part of the consideration for the issue of the Securities.

      SECTION 114. Conflict with Trust Indenture Act. If any provision hereof
limits, qualifies or conflicts with another provision hereof which is required
or deemed to be included in this Indenture by any of the provisions of the Trust
Indenture Act, such required provision shall control. If any provision of this
Indenture modifies or excludes any provision of the Trust Indenture Act that may
be so modified or excluded, the latter provision shall be deemed to apply to
this Indenture as so modified or to be excluded, as the case may be.


                         ARTICLE TWO - SECURITIES FORMS

      SECTION 201. Forms of Securities. The Registered Securities, if any, of
each series and the Bearer Securities, if any, of each series and related
coupons shall be substantially in the form of Exhibit A hereto or in such other
form as shall be established in one or more indentures supplemental hereto or
approved from time to time by or pursuant to a Board Resolution in accordance
with Section 301, shall have such appropriate insertions, omissions,
substitutions and other variations as are required or permitted by this
Indenture or any indenture supplemental hereto, and may have such letters,
numbers or other marks of identification or designation and such legends or
endorsements placed thereon as the Company may deem appropriate and as are not
inconsistent with the provisions of this Indenture, or as may be required to
comply with any law or with any rule or regulation made pursuant thereto or with
any rule or regulation of any stock exchange on which the Securities may be
listed, or to conform to usage.

      Unless otherwise specified as contemplated by Section 301, Bearer

<PAGE>   26
      SECTION 202. Form of Trustee's Certificate of Authentication. Subject to
Section 611, the Trustee's certificate of authentication shall be in
substantially the following form:

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

                                   [                   ]
                                   as Trustee


Dated: ______________              By:_______________________________
                                           Authorized Signatory

      SECTION 203. Securities Issuable in Global Form. If Securities of or
within a series are issuable in the form of one or more Global Securities, then,
notwithstanding clause (8) of Section 301 and the provisions of Section 302, any
such Global Security or Securities may provide that it or they shall represent
the aggregate amount of all Outstanding Securities of such series (or such
lesser amount as is permitted by the terms thereof) from time to time endorsed
thereon and may also provide that the aggregate amount of Outstanding Securities
of such series represented thereby may from time to time be increased or
decreased to reflect exchanges. Any endorsement of any Global Security to
reflect the amount, or any increase or decrease in the amount, or changes in the
rights of Holders thereof, of Outstanding Securities represented thereby shall
be made by the Trustee in such manner or by such Person or Persons as shall be
specified therein or in the Company Order to be delivered to the Trustee
pursuant to Section 303 or 304. Subject to the provisions of Section 303 and, if
applicable, Section 304, the Trustee shall deliver and redeliver any Global
Security in permanent global form in the manner and upon instructions given by
the Person or Persons specified therein or in the applicable Company Order. If a
Company Order pursuant to Section 303 or 304 has been, or simultaneously is,
delivered, any instructions by the Company with respect to endorsement or
delivery or redelivery of a Global Security shall be in writing but need not
comply with Section 102 and need not be accompanied by an Opinion of Counsel.

      The provisions of the last sentence of Section 303 shall apply to any
Security represented by a Global Security if such Security was never issued and
sold by the Company and the Company delivers to the Trustee the Global Security
together with written instructions (which need not comply with Section 102 and
need not be accompanied by an Opinion of Counsel) with regard to the reduction
in the principal amount of Securities represented thereby, together with the
written statement contemplated by the last sentence of Section 303.

      Notwithstanding the provisions of Section 307, unless otherwise specified
as contemplated by Section 301, payment of principal of and any premium or
Make-Whole Amount, if any, and interest on any Global Security in permanent
global form shall be made to the registered Holder thereof.


                                       19
<PAGE>   27
      Notwithstanding the provisions of Section 308 and except as provided in
the preceding paragraph, the Company, the Trustee and any agent of the Company
and the Trustee shall treat as the Holder of such principal amount of
Outstanding Securities represented by a permanent Global Security (i) in the
case of a permanent Global Security in registered form, the Holder of such
permanent Global Security in registered form, or (ii) in the case of a permanent
Global Security in bearer form, Euroclear or CEDEL.

      Any Global Security authenticated and delivered hereunder shall bear a
legend in substantially the following form:

            "This Security is a Global Security within the meaning set forth in
            the Indenture hereinafter referred to and is registered in the name
            of a Depository or a nominee of a Depository. This Security is
            exchangeable for Securities registered in the name of a person other
            than the Depository or its nominee only in the limited circumstances
            described in the Indenture, and may not be transferred except as a
            whole by the Depository to a nominee of the Depository or by a
            nominee of the Depository to the Depository or another nominee of
            the Depository or by the Depository or its nominee to a successor
            Depository or its nominee."


                         ARTICLE THREE - THE SECURITIES

      SECTION 301. Amount Unlimited; Issuable in Series. The aggregate principal
amount of Securities which may be authenticated and delivered under this
Indenture is unlimited.

one or more Board Resolutions and, subject to Section 303, set forth in an
Officers' Certificate, or established in one or more indentures supplemental
hereto, prior to the issuance of Securities of any series:

                  (1) The title of the Securities of the series (which shall
      distinguish the Securities of such series from all other series of
      Securities);

                  (2) Any limit upon the aggregate principal amount of the
      Securities of the series that may be authenticated and delivered under
      this Indenture (except for Securities authenticated and delivered upon
      registration of transfer of, or in exchange for, or in lieu of, other
      Securities of the series pursuant to Section 304, 305, 306, 906, 1107 or
      1305);

      prices at which and the other terms and conditions upon which such

      Company;

                  (10) The obligation, if any, of the Company to redeem, repay

      holders of Securities of the series upon the occurrence of such events as
      may be specified;

                  (15) Any deletions from, modifications of or additions to the
      Events of Default or covenants of the Company with respect to Securities

                                       22
<PAGE>   30
      of the series are to be issuable initially in temporary global form and
      whether any Securities of the series are to be issuable in permanent
      global form with or without coupons and, if so, whether beneficial owners
      of interests in any such permanent global Security may exchange such
      interests for Securities of such series and of like tenor of any
      authorized form and denomination and the circumstances under which any

      severally mature, and the extent to which, or the manner in which, any
      interest payable on a temporary Global Security on an Interest Payment
      Date will be paid if other than in the manner provided herein;

                  (20) The applicability, if any, of the defeasance and covenant
      defeasance provisions of Article Fourteen hereof to the Securities of the 
      series;

                  (21) If the Securities of such series are to be issuable in
      definitive form (whether upon original issue or upon exchange of a
      temporary Security of such series) only upon receipt of certain
      certificates or other documents or satisfaction of other conditions, then
      the form and/or terms of such certificates, documents or conditions;

                  (22) The obligation, if any, of the Company to permit the
      conversion of the Securities of such series into Common Stock or Preferred
      Stock, as the case may be, and the terms and conditions upon which such
      conversion shall be effected (including, without limitation, the initial
      conversion price or rate, the conversion period, any adjustment of the
      applicable conversion price and any requirements relative to the
      reservation of such shares for purposes of conversion); and

                  (23) Any other terms of the series (which terms shall not be
      inconsistent with the provisions of this Indenture).


                                       23
<PAGE>   31
      All Securities of any one series and the coupons appertaining to any
Bearer Securities of such series shall be substantially identical except, in the
case of Registered Securities, as to denomination and except as may otherwise be
provided in or pursuant to such Board Resolution (subject to Section 303) and
set forth in such Officers' Certificate or in any such indenture supplemental
hereto. All Securities of any one series need not be issued at the same time
and, unless otherwise provided, a series may be reopened, without the consent of
the Holders, for issuances of additional Securities of such series.

      If any of the terms of the Securities of any series are established by
action taken pursuant to one or more Board Resolutions, a copy of an appropriate
record of such action(s) shall be certified by the Secretary or an Assistant
Secretary of the Company and delivered to the Trustee at or prior to the
delivery of the Officers' Certificate setting forth the terms of the Securities
of such series.

      SECTION 302. Denominations. The Securities of each series shall be
issuable in such denominations as shall be specified as contemplated by Section
301. With respect to Securities of any series denominated in Dollars, in the
absence of any such provisions with respect to the Securities of any series, the
Securities of such series, other than Global Securities (which may be of any
denomination), shall be issuable in denominations of $1,000 and any integral
multiple thereof.

      SECTION 303. Execution, Authentication, Delivery and Dating. The
Securities and any coupons appertaining thereto shall be executed on behalf of
the Company by its Chairman of the Board, its President or one of its Vice
Presidents, under its corporate seal reproduced thereon, and attested by its
Secretary or one of its Assistant Secretaries. The signature of any of these
officers on the Securities and coupons may be manual or facsimile signatures of
the present or any future such authorized officer and may be imprinted or
otherwise reproduced on the Securities.

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

      At any time and from time to time after the execution and delivery of this
Indenture, the Company may deliver Securities of any series, together with any
coupon appertaining thereto, executed by the Company to the Trustee for
authentication, together with a Company Order for the authentication and
delivery of such Securities, and the Trustee in accordance with the Company
Order shall authenticate and deliver such Securities; provided, however, that,
in connection with its original issuance, no Bearer Security shall be mailed or
otherwise delivered to any location in the United States; and provided further
that, unless otherwise specified with respect to any series of Securities
pursuant to Section 301, a Bearer Security may be delivered in connection with
its original issuance only if the Person entitled to receive such Bearer


                                       24
<PAGE>   32
Security shall have furnished a certificate to Euroclear or CEDEL, as the case
may be, in the form set forth in Exhibit B-1 to this Indenture or such other
certificate as may be specified with respect to any series of Securities
pursuant to Section 301, dated no earlier than 15 days prior to the earlier of
the date on which such Bearer Security is delivered and the date on which any
temporary Security first becomes exchangeable for such Bearer Security in
accordance with the terms of such temporary Security and this Indenture. If any
Security shall be represented by a permanent global Bearer Security, then, for
purposes of this Section and Section 304, the notation of a beneficial owner's
interest therein upon original issuance of such Security or upon exchange of a
portion of a temporary Global Security shall be deemed to be delivery in
connection with its original issuance of such beneficial owner's interest in
such permanent Global Security. Except as permitted by Section 306, the Trustee
shall not authenticate and deliver any Bearer Security unless all appurtenant
coupons for interest then matured have been detached and canceled.

      If all the Securities of any series are not to be issued at one time and
if the Board Resolution or supplemental indenture establishing such series shall
so permit, such Company Order may set forth procedures acceptable to the Trustee
for the issuance of such Securities and determining the terms of particular
Securities of such series, such as interest rate or formula, maturity date, date
of issuance and date from which interest shall accrue. In authenticating such
Securities, and accepting the additional responsibilities under this Indenture
in relation to such Securities, the Trustee shall be entitled to receive, and
(subject to TIA Section 315(a) through 315(d)) shall be fully protected in
relying upon,

            (i) an Opinion of Counsel stating that

                  (a) the form or forms of such Securities and any coupons have 
            been established in conformity with the provisions of this 
            Indenture;

                  (b) the terms of such Securities and any coupons have been
            established in conformity with the provisions of this Indenture; and

                  (c) such Securities, together with any coupons appertaining
            thereto, when completed by appropriate insertions and executed and
            delivered by the Company to the Trustee for authentication in
            accordance with this Indenture, authenticated and delivered by the
            Trustee in accordance with this Indenture and issued by the Company
            in the manner and subject to any conditions specified in such
            Opinion of Counsel, will constitute legal, valid and legally binding
            obligations of the Company, enforceable in accordance with their
            terms, subject to applicable bankruptcy, insolvency, fraudulent
            transfer, reorganization and other similar laws of general
            applicability relating to or affecting the enforcement of creditors'
            rights generally and to general equitable principles; and


                                       25
<PAGE>   33
            (ii) an Officers' Certificate stating that all conditions precedent
      provided for in this Indenture relating to the issuance of the Securities
      have been complied with and that, to the best of the knowledge of the
      signers of such certificate, that no Event of Default with respect to any
      of the Securities shall have occurred and be continuing.

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

      Notwithstanding the provisions of Section 301 and of the preceding
paragraph, if all the Securities of any series are not to be issued at one time,
it shall not be necessary to deliver an Officers' Certificate otherwise required
pursuant to Section 301 or a Company Order, or an Opinion of Counsel or an
Officers' Certificate otherwise required pursuant to the preceding paragraph at
the time of issuance of each Security of such series, but such order, opinion
and certificates, with appropriate modifications to cover such future issuances,
shall be delivered at or before the time of issuance of the first Security of
such series.

      Each Registered Security shall be dated the date of its authentication and
each Bearer Security shall be dated as of the date specified as contemplated by
Section 301.

      No Security or coupon shall be entitled to any benefit under this
Indenture or be valid or obligatory for any purpose unless there appears on such
Security or Security to which such coupon appertains a certificate of
authentication substantially in the form provided for herein duly executed by
the Trustee by manual signature of an authorized signatory, and such certificate
upon any Security shall be conclusive evidence, and the only evidence, that such
Security has been duly authenticated and delivered hereunder and is entitled to
the benefits of this Indenture. Notwithstanding the foregoing, if any Security
(including a Global Security) shall have been authenticated and delivered
hereunder but never issued and sold by the Company, and the Company shall
deliver such Security to the Trustee for cancellation as provided in Section 309
together with a written statement (which need not comply with Section 102 and
need not be accompanied by an Opinion of Counsel) stating that such Security has
never been issued and sold by the Company, for all purposes of this Indenture
such Security shall be deemed never to have been authenticated and delivered
hereunder and shall never be entitled to the benefits of this Indenture.

      SECTION 304. Temporary Securities.

      (a) Pending the preparation of definitive Securities of any series, the
Company may execute, and upon Company Order the Trustee shall authenticate and
deliver, temporary Securities which are printed, lithographed, typewritten,
mimeographed or otherwise produced, in any authorized denomination,
substantially of the tenor of the definitive Securities in lieu of which they
are issued, in registered form, or, if authorized, in bearer form with one or
more coupons or without coupons, and with such appropriate insertions,
omissions, substitutions and


                                       26
<PAGE>   34
other variations as the officers executing such Securities may determine, as
conclusively evidenced by their execution of such Securities. In the case of
Securities of any series, such temporary Securities may be in global form.

      Except in the case of temporary Global Securities (which shall be
exchanged as otherwise provided herein or as otherwise provided in or pursuant
to a Board Resolution), if temporary Securities of any series are issued, the
Company will cause definitive Securities of that series to be prepared without
unreasonable delay. After the preparation of definitive Securities of such
series, the temporary Securities of such series shall be exchangeable for
definitive Securities of such series upon surrender of the temporary Securities
of such series at the office or agency of the Company in a Place of Payment for
that series, without charge to the Holder. Upon surrender for cancellation of
any one or more temporary Securities of any series (accompanied by any
non-matured coupons appertaining thereto), the Company shall execute and the
Trustee shall authenticate and deliver in exchange therefor a like principal
amount of definitive Securities of the same series of authorized denominations;
provided, however, that no definitive Bearer Security shall be delivered in
exchange for a temporary Registered Security; and provided further that a
definitive Bearer Security shall be delivered in exchange for a temporary Bearer
Security only in compliance with the conditions set forth in Section 303. Until
so exchanged, the temporary Securities of any series shall in all respects be
entitled to the same benefits under this Indenture as definitive Securities of
such series.

      (b) Unless otherwise provided in or pursuant to a Board Resolution, the
following provisions of this Section 304(b) shall govern the exchange of
temporary Securities other than through the facilities of The Depository Trust
Company. If any such temporary Security is issued in global form, then such
temporary Global Security shall, unless otherwise provided therein, be delivered
to the London office of a depository or common depository (the "Common
Depository"), for the benefit of Euroclear and CEDEL, for credit to the
respective accounts of the beneficial owners of such Securities (or to such
other accounts as they may direct).

      Without unnecessary delay but in any event not later than the date
specified in, or determined pursuant to the terms of, any such temporary Global
Security (the "Exchange Date"), the Company shall deliver to the Trustee
definitive Securities, in aggregate principal amount equal to the principal
amount of such temporary Global Security, executed by the Company. On or after
the Exchange Date, such temporary Global Security shall be surrendered by the
Common Depository to the Trustee, as the Company's agent for such purpose, to be
exchanged, in whole or from time to time in part, for definitive Securities
without charge, and the Trustee shall authenticate and deliver, in exchange for
each portion of such temporary Global Security, an equal aggregate principal
amount of definitive Securities of the same series of authorized denominations
and of like tenor as the portion of such temporary Global Security to be
exchanged. The definitive Securities to be delivered in exchange for any such
temporary Global Security shall be in bearer form, registered form, permanent
global bearer form or permanent global registered form, or any combination
thereof, as specified as contemplated by Section 301, and, if any combination
thereof is so specified, as requested by


                                       27
<PAGE>   35
the beneficial owner thereof; provided, however, that, unless otherwise
specified in such temporary Global Security, upon such presentation by the
Common Depository, such temporary Global Security is accompanied by a
certificate dated the Exchange Date or a subsequent date and signed by Euroclear
as to the portion of such temporary Global Security held for its account then to
be exchanged and a certificate dated the Exchange Date or a subsequent date and
signed by CEDEL as to the portion of such temporary Global Security held for its
account then to be exchanged, each in the form set forth in Exhibit A-2 to this
Indenture or in such other form as may be established pursuant to Section 301;
and provided further that definitive Bearer Securities shall be delivered in
exchange for a portion of a temporary Global Security only in compliance with
the requirements of Section 303.

      Unless otherwise specified in such temporary Global Security, the interest
of a beneficial owner of Securities of a series in a temporary Global Security
shall be exchanged for definitive Securities of the same series and of like
tenor following the Exchange Date when the account holder instructs Euroclear or
CEDEL, as the case may be, to request such exchange on his behalf and delivers
to Euroclear or CEDEL, as the case may be, a certificate in the form set forth
in Exhibit B-1 to this Indenture (or in such other form as may be established
pursuant to Section 301), dated no earlier than 15 days prior to the Exchange
Date, copies of which certificate shall be available from the offices of
Euroclear and CEDEL, the Trustee, any Authenticating Agent appointed for such
series of Securities and each Paying Agent. Unless otherwise specified in such
temporary Global Security, any such exchange shall be made free of charge to the
beneficial owners of such temporary Global Security, except that a Person
receiving definitive Securities must bear the cost of insurance, postage,
transportation and the like unless such Person takes delivery of such definitive
Securities in person at the offices of Euroclear or CEDEL. Definitive Securities
in bearer form to be delivered in exchange for any portion of a temporary Global
Security shall be delivered only outside the United States.

      Until exchanged in full as hereinabove provided, the temporary Securities
of any series shall in all respects be entitled to the same benefits under this
Indenture as definitive Securities of the same series and of like tenor
authenticated and delivered hereunder, except that, unless otherwise specified
as contemplated by Section 301, interest payable on a temporary Global Security
on an Interest Payment Date for Securities of such series occurring prior to the
applicable Exchange Date shall be payable to Euroclear and CEDEL on such
Interest Payment Date upon delivery by Euroclear and CEDEL to the Trustee of a
certificate or certificates in the form set forth in Exhibit B-2 to this
Indenture (or in such other forms as may be established pursuant to Section
301), for credit without further interest on or after such Interest Payment Date
to the respective accounts of Persons who are the beneficial owners of such
temporary Global Security on such Interest Payment Date and who have each
delivered to Euroclear or CEDEL, as the case may be, a certificate dated no
earlier than 15 days prior to the Interest Payment Date occurring prior to such
Exchange Date in the form set forth as Exhibit B-1 to this Indenture (or in such
other forms as may be established pursuant to Section 301). Notwithstanding
anything to the contrary herein contained, the certifications made pursuant to
this paragraph shall satisfy the certification requirements of the preceding two
paragraphs of this Section 304(b) and of the third paragraph of Section 303 of
this Indenture and the interests


                                       28
<PAGE>   36
of the Persons who are the beneficial owners of the temporary Global Security
with respect to which such certification was made will be exchanged for
definitive Securities of the same series and of like tenor on the Exchange Date
or the date of certification if such date occurs after the Exchange Date,
without further act or deed by such beneficial owners. Except as otherwise
provided in this paragraph, no payments of principal or interest owing with
respect to a beneficial interest in a temporary Global Security will be made
unless and until such interest in such temporary Global Security shall have been
exchanged for an interest in a definitive Security. Any interest so received by
Euroclear and CEDEL and not paid as herein provided shall be returned to the
Trustee prior to the expiration of two years after such Interest Payment Date in
order to be repaid to the Company.

      SECTION 305. Registration, Registration of Transfer and Exchange. The
Company shall cause to be kept at the Corporate Trust Office of the Trustee or
in any office or agency of the Company in a Place of Payment a register for each
series of Securities (the registers maintained in such office or in any such
office or agency of the Company in a Place of Payment being herein sometimes
referred to collectively as the "Security Register") in which, subject to such
reasonable regulations as it may prescribe, the Company shall provide for the
registration of Registered Securities and of transfers of Registered Securities.
The Security Register shall be in written form or any other form capable of
being converted into written form within a reasonable time. The Trustee, at its
Corporate Trust Office, is hereby initially appointed "Security Registrar" for
the purpose of registering Registered Securities and transfers of Registered
Securities on such Security Register as herein provided. In the event that the
Trustee shall cease to be Security Registrar, it shall have the right to examine
the Security Register at all reasonable times.

      Subject to the provisions of this Section 305, upon surrender for
registration of transfer of any Registered Security of any series at any office
or agency of the Company in a Place of Payment for that series, the Company
shall execute, and the Trustee shall authenticate and deliver, in the name of
the designated transferee or transferees, one or more new Registered Securities
of the same series, of any authorized denominations and of a like aggregate
principal amount, bearing a number not contemporaneously outstanding, and
containing identical terms and provisions.

      Subject to the provisions of this Section 305, at the option of the
Holder, Registered Securities of any series may be exchanged for other
Registered Securities of the same series, of any authorized denomination or
denominations and of a like aggregate principal amount, containing identical
terms and provisions, upon surrender of the Registered Securities to be
exchanged at any such office or agency. Whenever any such Registered Securities
are so surrendered for exchange, the Company shall execute, and the Trustee
shall authenticate and deliver, the Registered Securities which the Holder
making the exchange is entitled to receive. Unless otherwise specified with
respect to any series of Securities as contemplated by Section 301, Bearer
Securities may not be issued in exchange for Registered Securities.


                                       29
<PAGE>   37
      If (but only if) permitted by the applicable Board Resolution and (subject
to Section 303) set forth in the applicable Officers' Certificate, or in any
indenture supplemental hereto, delivered as contemplated by Section 301, at the
option of the Holder, Bearer Securities of any series may be exchanged for
Registered Securities of the same series of any authorized denominations and of
a like aggregate principal amount and tenor, upon surrender of the Bearer
Securities to be exchanged at any such office or agency, with all unmatured
coupons and all matured coupons in default thereto appertaining. If the Holder
of a Bearer Security is unable to produce any such unmatured coupon or coupons
or matured coupon or coupons in default, any such permitted exchange may be
effected if the Bearer Securities are accompanied by payment in funds acceptable
to the Company in an amount equal to the face amount of such missing coupon or
coupons, or the surrender of such missing coupon or coupons may be waived by the
Company and the Trustee if there is furnished to them such security or indemnity
as they may require to save each of them and any Paying Agent harmless. If
thereafter the Holder of such Security shall surrender to any Paying Agent any
such missing coupon in respect of which such a payment shall have been made,
such Holder shall be entitled to receive the amount of such payment; provided,
however, that, except as otherwise provided in Section 1002, interest
represented by coupons shall be payable only upon presentation and surrender of
those coupons at an office or agency located outside the United States.
Notwithstanding the foregoing, in case a Bearer Security of any series is
surrendered at any such office or agency in a permitted exchange for a
Registered Security of the same series and like tenor after the close of
business at such office or agency on (i) any Regular Record Date and before the
opening of business at such office or agency on the relevant Interest Payment
Date, or (ii) any Special Record Date and before the opening of business at such
office or agency on the related proposed date for payment of Defaulted Interest,
such Bearer Security shall be surrendered without the coupon relating to such
Interest Payment Date or proposed date for payment, as the case may be, and
interest or Defaulted Interest, as the case may be, will not be payable on such
Interest Payment Date or proposed date for payment, as the case may be, in
respect of the Registered Security issued in exchange for such Bearer Security,
but will be payable only to the Holder of such coupon when due in accordance
with the provisions of this Indenture. Whenever any Securities are so
surrendered for exchange, the Company shall execute, and the Trustee shall
authenticate and deliver, the Securities which the Holder making the exchange is
entitled to receive.

      Notwithstanding the foregoing, except as otherwise specified as
contemplated by Section 301, any permanent Global Security shall be exchangeable
only as provided in this paragraph. If the depository for any permanent Global
Security is The Depository Trust Company ("DTC"), then, unless the terms of such
Global Security expressly permit such Global Security to be exchanged in whole
or in part for definitive Securities, a Global Security may be transferred, in
whole but not in part, only to a nominee of DTC, or by a nominee of DTC to DTC,
or to a successor to DTC for such Global Security selected or approved by the
Company or to a nominee of such successor to DTC. If at any time DTC notifies
the Company that it is unwilling or unable to continue as depository for the
applicable Global Security or Securities or if at any time DTC ceases to be a
clearing agency registered under the Securities Exchange Act of 1934 if so
required by applicable law or regulation, the Company


                                       30
<PAGE>   38
shall appoint a successor depository with respect to such Global Security or
Securities. If (x) a successor depository for such Global Security or Securities
is not appointed by the Company within 90 days after the Company receives such
notice or becomes aware of such unwillingness, inability or ineligibility, (y)
an Event of Default has occurred and is continuing and the beneficial owners
representing a majority in principal amount of the applicable series of
Securities represented by such Global Security or Securities advise DTC to cease
acting as depository for such Global Security or Securities or (z) the Company,
in its sole discretion, determines at any time that all Outstanding Securities
(but not less than all) of any series issued or issuable in the form of one or
more Global Securities shall no longer be represented by such Global Security or
Securities, then the Company shall execute, and the Trustee shall authenticate
and deliver definitive Securities of like series, rank, tenor and terms in
definitive form in an aggregate principal amount equal to the principal amount
of such Global Security or Securities. If any beneficial owner of an interest in
a permanent global Security is otherwise entitled to exchange such interest for
Securities of such series and of like tenor and principal amount of another
authorized form and denomination, as specified as contemplated by Section 301
and provided that any applicable notice provided in the permanent Global
Security shall have been given, then without unnecessary delay but in any event
not later than the earliest date on which such interest may be so exchanged, the
Company shall execute, and the Trustee shall authenticate and deliver definitive
Securities in aggregate principal amount equal to the principal amount of such
beneficial owner's interest in such permanent Global Security. On or after the
earliest date on which such interests may be so exchanged, such permanent Global
Security shall be surrendered for exchange by DTC or such other depository as
shall be specified in the Company Order with respect thereto to the Trustee, as
the Company's agent for such purpose; provided, however, that no such exchanges
may occur during a period beginning at the opening of business 15 days before
any selection of Securities to be redeemed and ending on the relevant Redemption
Date if the Security for which exchange is requested may be among those selected
for redemption; and provided further that no Bearer Security delivered in
exchange for a portion of a permanent Global Security shall be mailed or
otherwise delivered to any location in the United States. If a Registered
Security is issued in exchange for any portion of a permanent Global Security
after the close of business at the office or agency where such exchange occurs
on (i) any Regular Record Date and before the opening of business at such office
or agency on the relevant Interest Payment Date, or (ii) any Special Record Date
and the opening of business at such office or agency on the related proposed
date for payment of Defaulted Interest, interest or Defaulted Interest, as the
case may be, will not be payable on such Interest Payment Date or proposed date
for payment, as the case may be, in respect of such Registered Security, but
will be payable on such Interest Payment Date or proposed date for payment, as
the case may be, only to the Person to whom interest in respect of such portion
of such permanent Global Security is payable in accordance with the provisions
of this Indenture.

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


                                       31
<PAGE>   39
      Every Registered Security presented or surrendered for registration of
transfer or for exchange or redemption shall (if so required by the Company or
the Security Registrar) be duly endorsed, or be accompanied by a written
instrument of transfer in form satisfactory to the Company and the Security
Registrar, duly executed by the Holder thereof or his attorney duly authorized
in writing.

      No service charge shall be made for any registration of transfer or
exchange of Securities, but the Company may require payment of a sum sufficient
to cover any tax or other governmental charge that may be imposed in connection
with any registration of transfer or exchange of Securities, other than
exchanges pursuant to Section 304, 906, 1107 or 1305 not involving any transfer.

      The Company or the Trustee, as applicable, shall not be required (i) to
issue, register the transfer of or exchange any Security if such Security may be
among those selected for redemption during a period beginning at the opening of
business 15 days before selection of the Securities to be redeemed under Section
1103 and ending at the close of business on (A) if such Securities are issuable
only as Registered Securities, the day of the mailing of the relevant notice of
redemption and (B) if such Securities are issuable as Bearer Securities, the day
of the first publication of the relevant notice of redemption or, if such
Securities are also issuable as Registered Securities and there is no
publication, the mailing of the relevant notice of redemption, or (ii) to
register the transfer of or exchange any Registered Security so selected for
redemption in whole or in part, except, in the case of any Registered Security
to be redeemed in part, the portion thereof not to be redeemed, or (iii) to
exchange any Bearer Security so selected for redemption except that such a
Bearer Security may be exchanged for a Registered Security of that series and
like tenor, provided that such Registered Security shall be simultaneously
surrendered for redemption, or (iv) to issue, register the transfer of or
exchange any Security which has been surrendered for repayment at the option of
the Holder, except the portion, if any, of such Security not to be so repaid.

      SECTION 306. Mutilated, Destroyed, Lost and Stolen Securities. If any
mutilated Security or a Security with a mutilated coupon appertaining to it is
surrendered to the Trustee or the Company, together with, in proper cases, such
security or indemnity as may be required by the Company or the Trustee to save
each of them or any agent of either of them harmless, the Company shall execute
and the Trustee shall authenticate and deliver in exchange therefor a new
Security of the same series and principal amount, containing identical terms and
provisions and bearing a number not contemporaneously outstanding, with coupons
corresponding to the coupons, if any, appertaining to the surrendered Security.

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


                                       32
<PAGE>   40
Security or in exchange for the Security to which a destroyed, lost or stolen
coupon appertains (with all appurtenant coupons not destroyed, lost or stolen),
a new Security of the same series and principal amount, containing identical
terms and provisions and bearing a number not contemporaneously outstanding,
with coupons corresponding to the coupons, if any, appertaining to such
destroyed, lost or stolen Security or to the Security to which such destroyed,
lost or stolen coupon appertains.

      Notwithstanding the provisions of the previous two paragraphs, in case any
such mutilated, destroyed, lost or stolen Security or coupon has become or is
about to become due and payable, the Company in its discretion may, instead of
issuing a new Security, with coupons corresponding to the coupons, if any,
appertaining to such destroyed, lost or stolen Security or to the Security to
which such destroyed, lost or stolen coupon appertains, pay such Security or
coupon; provided, however, that payment of principal of (and premium or
Make-Whole Amount, if any), and any interest on, Bearer Securities shall, except
as otherwise provided in Section 1002, be payable only at an office or agency
located outside the United States and, unless otherwise specified as
contemplated by Section 301, any interest on Bearer Securities shall be payable
only upon presentation and surrender of the coupons appertaining thereto.

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

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

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

      SECTION 307. Payment of Interest; Interest Rights Preserved. Except as
otherwise specified with respect to a series of Securities in accordance with
the provisions of Section 301, interest on any Registered Security that is
payable, and is punctually paid or duly provided for, on any Interest Payment
Date shall be paid to the Person in whose name that Security (or one or more
Predecessor Securities) is registered at the close of business on the Regular
Record Date for such interest at the office or agency of the Company maintained
for such purpose pursuant to Section 1002; provided, however, that each
installment of interest on any Registered Security may at the Company's option
be paid by (i) mailing a check for such


                                       33
<PAGE>   41
interest, payable to or upon the written order of the Person entitled thereto
pursuant to Section 308, to the address of such Person as it appears on the
Security Register or (ii) transfer to an account maintained by the payee located
inside the United States.

      Unless otherwise provided as contemplated by Section 301 with respect to
the Securities of any series, payment of interest may be made, in the case of a
Bearer Security, by transfer to an account maintained by the payee with a bank
located outside the United States.

      Unless otherwise provided as contemplated by Section 301, every permanent
global Security will provide that interest, if any, payable on any Interest
Payment Date will be paid to DTC, Euroclear and/or CEDEL, as the case may be,
with respect to that portion of such permanent global Security held for its
account by Cede & Co. or the Common Depository, as the case may be, for the
purpose of permitting such party to credit the interest received by it in
respect of such permanent global Security to the accounts of the beneficial
owners thereof.

      In case a Bearer Security of any series is surrendered in exchange for a
Registered Security of such series after the close of business (at an office or
agency in a Place of Payment for such series) on any Regular Record Date and
before the opening of business (at such office or agency) on the next succeeding
Interest Payment Date, such Bearer Security shall be surrendered without the
coupon relating to such Interest Payment Date and interest will not be payable
on such Interest Payment Date in respect of the Registered Security issued in
exchange for such Bearer Security, but will be payable only to the Holder of
such coupon when due in accordance with the provisions of this Indenture.

      Except as otherwise specified with respect to a series of Securities in
accordance with the provisions of Section 301, any interest on any Registered
Security of any series that is payable, but is not punctually paid or duly
provided for, on any Interest Payment Date (herein called "Defaulted Interest")
shall forthwith cease to be payable to the registered Holder thereof on the
relevant Regular Record Date by virtue of having been such Holder, and such
Defaulted Interest may be paid by the Company, at its election in each case, as
provided in clause (1) or (2) below:

                  (1) The Company may elect to make payment of any Defaulted
      Interest to the Persons in whose names the Registered Securities of such
      series (or their respective Predecessor Securities) are registered at the
      close of business on a Special Record Date for the payment of such
      Defaulted Interest, which shall be fixed in the following manner. The
      Company shall notify the Trustee in writing of the amount of Defaulted
      Interest proposed to be paid on each Registered Security of such series
      and the date of the proposed payment (which shall not be less than 20 days
      after such notice is received by the Trustee), and at the same time the
      Company shall deposit with the Trustee an amount of money in the currency
      or currencies, currency unit or units or composite currency or currencies
      in which the Securities of such series are payable (except as otherwise
      specified pursuant to Section 301 for the Securities of such series) equal
      to the aggregate amount proposed to be paid in respect of such Defaulted
      Interest


                                       34
<PAGE>   42
      or shall make arrangements satisfactory to the Trustee for such deposit on
      or prior to the date of the proposed payment, such money when deposited to
      be held in trust for the benefit of the Persons entitled to such Defaulted
      Interest as in this clause provided. Thereupon the Trustee shall fix a
      Special Record Date for the payment of such Defaulted Interest which shall
      be not more than 15 days and not less than 10 days prior to the date of
      the proposed payment and not less than 10 days after the receipt by the
      Trustee of the notice of the proposed payment. The Trustee shall promptly
      notify the Company of such Special Record Date and, in the name and at the
      expense of the Company, shall cause notice of the proposed payment of such
      Defaulted Interest and the Special Record Date therefor to be mailed,
      first-class postage prepaid, to each Holder of Registered Securities of
      such series at his address as it appears in the Security Register not less
      than 10 days prior to such Special Record Date. The Trustee may, in its
      discretion, in the name and at the expense of the Company, cause a similar
      notice to be published at least once in an Authorized Newspaper in each
      Place of Payment, but such publications shall not be a condition precedent
      to the establishment of such Special Record Date. Notice of the proposed
      payment of such Defaulted Interest and the Special Record Date therefor
      having been mailed as aforesaid, such Defaulted Interest shall be paid to
      the Persons in whose names the Registered Securities of such series (or
      their respective Predecessor Securities) are registered at the close of
      business on such Special Record Date and shall no longer be payable
      pursuant to the following clause (2). In case a Bearer Security of any
      series is surrendered at the office or agency in a Place of Payment for
      such series in exchange for a Registered Security of such series after the
      close of business at such office or agency on any Special Record Date and
      before the opening of business at such office or agency on the related
      proposed date for payment of Defaulted Interest, such Bearer Security
      shall be surrendered without the coupon relating to such proposed date of
      payment and Defaulted Interest will not be payable on such proposed date
      of payment in respect of the Registered Security issued in exchange for
      such Bearer Security, but will be payable only to the Holder of such
      coupon when due in accordance with the provisions of this Indenture.

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

      Subject to the foregoing provisions of this Section and Section 305, each
Security delivered under this Indenture upon registration of transfer of or in
exchange for or in lieu of any other Security shall carry the rights to interest
accrued and unpaid, and to accrue, which were carried by such other Security.

      SECTION 308. Persons Deemed Owners. Prior to due presentment of a
Registered Security for registration of transfer, the Company, the Trustee and
any agent of the Company


                                       35
<PAGE>   43
or the Trustee may treat the Person in whose name such Registered Security is
registered as the owner of such Security for the purpose of receiving payment of
principal of (and premium or Make-Whole Amount, if any), and (subject to
Sections 305 and 307) interest on, such Registered Security and for all other
purposes whatsoever, whether or not such Registered Security be overdue, and
neither the Company, the Trustee nor any agent of the Company or the Trustee
shall be affected by notice to the contrary. All such payments so made to any
such Person, or upon such Person's order, shall be valid, and, to the extent of
the sum or sums so paid, effectual to satisfy and discharge the liability for
money payable upon any such Security.

      Title to any Bearer Security and any coupons appertaining thereto shall
pass by delivery. The Company, the Trustee and any agent of the Company or the
Trustee may treat the Holder of any Bearer Security and the Holder of any coupon
as the absolute owner of such Security or coupon for the purpose of receiving
payment thereof or on account thereof and for all other purposes whatsoever,
whether or not such Security or coupon be overdue, and neither the Company, the
Trustee nor any agent of the Company or the Trustee shall be affected by notice
to the contrary.

      No Holder of any beneficial interest in any Global Security held on its
behalf by a depository shall have any rights under this Indenture with respect
to such Global Security and such depository shall be treated by the Company, the
Trustee, and any agent of the Company or the Trustee as the owner of such Global
Security for all purposes whatsoever. None of the Company, the Trustee, any
Paying Agent or the Security Registrar will have any responsibility or liability
for any aspect of the records relating to or payments made on account of
beneficial ownership interests of a Global Security or for maintaining,
supervising or reviewing any records relating to such beneficial ownership
interests.

      Notwithstanding the foregoing, with respect to any Global Security,
nothing herein shall prevent the Company, the Trustee, or any agent of the
Company or the Trustee, from giving effect to any written certification, proxy
or other authorization furnished by any depository, as a Holder, with respect to
such Global Security or impair, as between such depository and owners of
beneficial interests in such Global Security, the operation of customary
practices governing the exercise of the rights of such depository (or its
nominee) as Holder of such Global Security.

      SECTION 309. Cancellation. All Securities and coupons surrendered for
payment, redemption, repayment at the option of the Holder, conversion or
registration of transfer or exchange or for credit against any sinking fund
payment shall, if surrendered to any Person other than the Trustee, be delivered
to the Trustee, and any such Securities and coupons and Securities and coupons
surrendered directly to the Trustee for any such purpose shall be promptly
cancelled by it. The Company may at any time deliver to the Trustee for
cancellation any Securities previously authenticated and delivered hereunder
which the Company may have acquired in any manner whatsoever, and may deliver to
the Trustee (or to any other Person for delivery to the Trustee) for
cancellation any Securities previously authenticated hereunder which the Company
has not issued and sold, and all Securities so delivered shall be promptly


                                       36
<PAGE>   44
cancelled by the Trustee. If the Company shall so acquire any of the Securities,
however, such acquisition shall not operate as a redemption or satisfaction of
the indebtedness represented by such Securities unless and until the same are
surrendered to the Trustee for cancellation. No Securities shall be
authenticated in lieu of or in exchange for any Securities cancelled as provided
in this Section, except as expressly permitted by this Indenture. Cancelled
Securities and coupons held by the Trustee shall be destroyed by the Trustee and
the Trustee shall deliver a certificate of such destruction to the Company,
unless the Trustee is otherwise directed by a Company Order.

      SECTION 310. Computation of Interest. Except as otherwise specified as
contemplated by Section 301 with respect to Securities of any series, interest
on the Securities of each series shall be computed on the basis of a 360-day
year consisting of twelve 30-day months.


                    ARTICLE FOUR - SATISFACTION AND DISCHARGE

      SECTION 401. Satisfaction and Discharge of Indenture. This Indenture shall
upon Company Request cease to be of further effect with respect to any series of
Securities specified in such Company Request (except as to any surviving rights
of registration of transfer or exchange of Securities of such series herein
expressly provided for), and the Trustee, upon receipt of a Company Order, and
at the expense of the Company, shall execute instruments in form and substance
satisfactory to the Trustee and the Company acknowledging satisfaction and
discharge of this Indenture as to such series when

                  (1) either

                  (A) all Securities of such series theretofore authenticated
            and delivered and all coupons, if any, appertaining thereto (other
            than (i) coupons appertaining to Bearer Securities surrendered for
            exchange for Registered Securities and maturing after such exchange,
            whose surrender is not required or has been waived as provided in
            Section 305, (ii) Securities and coupons of such series which have
            been destroyed, lost or stolen and which have been replaced or paid
            as provided in Section 306, (iii) coupons appertaining to Securities
            called for redemption and maturing after the relevant Redemption
            Date, whose surrender has been waived as provided in Section 1106,
            and (iv) Securities and coupons of such series for whose payment
            money has theretofore been deposited in trust or segregated and held
            in trust by the Company and thereafter repaid to the Company or
            discharged from such trust, as provided in Section 1003) have been
            delivered to the Trustee for cancellation; or

                  (B) all Securities of such series and, in the case of (i) or
            (ii) below, any coupons appertaining thereto not theretofore
            delivered to the Trustee for cancellation


                                       37
<PAGE>   45
                        (i) have become due and payable, or

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

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

            and the Company, in the case of (i), (ii) or (iii) above, has
            irrevocably deposited or caused to be deposited with the Trustee as
            trust funds in trust for the purpose an amount in the currency or
            currencies, currency unit or units or composite currency or
            currencies in which the Securities of such series are payable,
            sufficient to pay and discharge the entire indebtedness on such
            Securities and such coupons not theretofore delivered to the Trustee
            for cancellation, for principal (and premium or Make-Whole Amount,
            if any) and interest to the date of such deposit (in the case of
            Securities which have become due and payable) or to the Stated
            Maturity or Redemption Date, as the case may be;

                  (2) the Company has paid or caused to be paid all other sums 
      payable hereunder by the Company; and

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

Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Company to the Trustee and any predecessor Trustee under
Section 606, the obligations of the Company to any Authenticating Agent under
Section 611 and, if money shall have been deposited with and held by the Trustee
pursuant to subclause (B) of clause (1) of this Section, the obligations of the
Trustee under Section 402 and the last paragraph of Section 1003 shall survive.

      SECTION 402. Application of Trust Funds. Subject to the provisions of the
last paragraph of Section 1003, all money deposited with the Trustee pursuant to
Section 401 shall be held in trust and applied by it, in accordance with the
provisions of the Securities, the coupons and this Indenture, to the payment,
either directly or through any Paying Agent (including the Company acting as its
own Paying Agent) as the Trustee may determine, to the Persons entitled thereto,
of the principal (and premium or Make-Whole Amount, if any), and any interest
for whose payment such money has been deposited with or received by the Trustee,
but such money need not be segregated from other funds except to the extent
required by law.

                             ARTICLE FIVE - REMEDIES

      SECTION 501. Events of Default. "Event of Default," wherever used herein
with respect to any particular series of Securities, means any one of the
following events (whatever the reason for such Event of Default and whether or
not it shall be voluntary or involuntary or be effected by operation of law or
pursuant to any judgment, decree or order of any court or any order, rule or
regulation of any administrative or governmental body):

                  (1) default in the payment of any interest on any Security of
      that series or of any coupon appertaining thereto, when such interest or
      coupon becomes due and payable, and continuance of such default for a
      period of 30 days; or

                  (2) default in the payment of the principal of (or premium or
      Make-Whole Amount, if any, on) any Security of that series when it becomes
      due and payable at its Maturity; or

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

                  (4) default in the performance, or breach, of any covenant or
      warranty of the Company in this Indenture with respect to any Security of
      that series (other than a covenant or warranty a default in whose
      performance or whose breach is elsewhere in this Section specifically
      dealt with), and continuance of such default or breach for a period of 60
      days after there has been given, by registered or certified mail, to the
      Company by the Trustee or to the Company and the Trustee by the Holders of
      at least 25% in principal amount of the Outstanding Securities of that
      series a written notice specifying such default or breach and requiring it
      to be remedied and stating that such notice is a "Notice of Default"
      hereunder; or

                  (5) default under any bond, debenture, note, mortgage,
      indenture or instrument under which there may be issued or by which there
      may be secured or evidenced any indebtedness for money borrowed by the
      Company (or by any Subsidiary, the repayment of which the Company has
      guaranteed or for which the Company is directly responsible or liable as
      obligor or guarantor), having an aggregate principal amount outstanding of
      at least $25,000,000, whether such indebtedness now exists or shall
      hereafter be created, which default shall have resulted in such
      indebtedness becoming or being declared due and payable prior to the date
      on which it would otherwise have become due and payable, without such
      indebtedness having been discharged, or such acceleration having been
      rescinded or annulled, within a period of 10 days after there shall have
      been given, by registered or certified mail, to the Company by the Trustee
      or to the Company and the Trustee by the Holders of at least 10% in
      principal amount of the Outstanding Securities of that series a written
      notice specifying such default and requiring the Company to cause such
      indebtedness to be


                                       39
<PAGE>   47
      discharged or cause such acceleration to be rescinded or annulled and
      stating that such notice is a "Notice of Default" hereunder; or

                  (6) the Company or any Significant Subsidiary pursuant to or 
      within the meaning of any Bankruptcy Law:

                        (A) commences a voluntary case,

                        (B) consents to the entry of an order for relief against
            it in an involuntary case,

                        (C) consents to the appointment of a Custodian of it or 
            for all or substantially all of its property, or

                        (D) makes a general assignment for the benefit of its 
            creditors; or

                  (7) a court of competent jurisdiction enters an order or
      decree under any Bankruptcy Law that:

                        (A) is for relief against the Company or any Significant
            Subsidiary in an involuntary case,

                        (B) appoints a Custodian of the Company or any 
            Significant Subsidiary or for all or substantially all of either of 
            its property, or

                        (C) orders the liquidation of the Company or any
            Significant Subsidiary, and the order or decree remains unstayed and
            in effect for 90 days; or

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

As used in this Section 501, the term "Bankruptcy Law" means title 11, U.S. Code
or any similar Federal or state law for the relief of debtors and the term
"Custodian" means any receiver, trustee, assignee, liquidator or other similar
official under any Bankruptcy Law.

      SECTION 502. Acceleration of Maturity; Rescission and Annulment. If an
Event of Default with respect to Securities of any series at the time
Outstanding occurs and is continuing, then and in every such case the Trustee or
the Holders of not less than 25% in principal amount of the Outstanding
Securities of that series may declare the principal amount (or, if Securities of
that Series are Original Issue Discount Securities or Indexed Securities, such
portion of the principal as may be specified in the terms thereof) of all the
Securities of that series to be due and payable immediately, by a notice in
writing to the Company (and to


                                       40
<PAGE>   48
the Trustee if given by the Holders), and upon any such declaration such
principal or specified portion thereof shall become immediately due and payable.

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

                  (1) the Company has paid or deposited with the Trustee a sum
      sufficient to pay in the currency, currency unit or composite currency in
      which the Securities of such series are payable (except as otherwise
      specified pursuant to Section 301 for the Securities of such series):

                        (A) all overdue installments of interest on all 
            Outstanding Securities of that series and any related coupons,

                        (B) the principal of (and premium or Make-Whole Amount,
            if any, on) any Outstanding Securities of that series which have
            become due otherwise than by such declaration of acceleration and
            interest thereon at the rate or rates borne by or provided for in
            such Securities,

                        (C) to the extent that payment of such interest is
            lawful, interest upon overdue installments of interest at the rate
            or rates borne by or provided for in such Securities, and

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

                  (2) all Events of Default with respect to Securities of that
      series, other than the nonpayment of the principal of (or premium or
      Make-Whole Amount, if any) or interest on Securities of that series which
      have become due solely by such declaration of acceleration, have been
      cured or waived as provided in Section 513.

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

      SECTION 503. Collection of Indebtedness and Suits for Enforcement by
Trustee. The Company covenants that if:

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


                                       41
<PAGE>   49
                  (2) default is made in the payment of the principal of (or 
      premium or Make-Whole Amount, if any, on) any Security of any series at 
      its Maturity,

then the Company will, upon demand of the Trustee, pay to the Trustee, for the
benefit of the Holders of such Securities of such series and coupons, the whole
amount then due and payable on such Securities and coupons for principal (and
premium or Make-Whole Amount, if any) and interest, with interest upon any
overdue principal (and premium or Make-Whole Amount, if any) and, to the extent
that payment of such interest shall be legally enforceable, upon any overdue
installments of interest at the rate or rates borne by or provided for in such
Securities, and, in addition thereto, such further amount as shall be sufficient
to cover the costs and expenses of collection, including the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel.

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

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

      SECTION 504. Trustee May File Proofs of Claim. In case of the pendency of
any receivership, insolvency, liquidation, bankruptcy, reorganization,
arrangement, adjustment, composition or other judicial proceeding relative to
the Company or any other obligor upon the Securities or the property of the
Company or of such other obligor or their creditors, the Trustee (irrespective
of whether the principal of the Securities of any series shall then be due and
payable as therein expressed or by declaration or otherwise and irrespective of
whether the Trustee shall have made any demand on the Company for the payment of
overdue principal, premium or Make-Whole Amount, if any, or interest) shall be
entitled and empowered, by intervention in such proceeding or otherwise:

                        (i) to file and prove a claim for the whole amount, or
      such lesser amount as may be provided for in the Securities of such
      series, of principal (and premium or Make-Whole Amount, if any) and
      interest owing and unpaid in respect of the Securities and to file such
      other papers or documents as may be necessary or advisable in order to
      have the claims of the Trustee (including any claim for the


                                       42
<PAGE>   50
      reasonable compensation, expenses, disbursements and advances of the
      Trustee, its agents and counsel) and of the Holders allowed in such
      judicial proceeding, and

                        (ii) to collect and receive any moneys or other property
      payable or deliverable on any such claims and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator (or
other similar official) in any such judicial proceeding is hereby authorized by
each Holder of Securities of such series and coupons to make such payments to
the Trustee, and in the event that the Trustee shall consent to the making of
such payments directly to the Holders, to pay to the Trustee any amount due to
it for the reasonable compensation, expenses, disbursements and advances of the
Trustee and any predecessor Trustee, their agents and counsel, and any other
amounts due the Trustee or any predecessor Trustee under Section 606.

      Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder of a Security
or coupon any plan of reorganization, arrangement, adjustment or composition
affecting the Securities or coupons or the rights of any Holder thereof, or to
authorize the Trustee to vote in respect of the claim of any Holder of a
Security or coupon in any such proceeding.

      In any proceedings brought by the Trustee (and also any proceedings
involving the interpretation of any provision of this Indenture to which the
Trustee shall be a party) the Trustee shall be held to represent all the Holders
of the Securities, and it shall not be necessary to make any Holders of the
Securities parties to any such proceedings.

      SECTION 505. Trustee May Enforce Claims Without Possession of Securities
or Coupons. All rights of action and claims under this Indenture or any of the
Securities or coupons may be prosecuted and enforced by the Trustee without the
possession of any of the Securities or coupons or the production thereof in any
proceeding relating thereto, and any such proceeding instituted by the Trustee
shall be brought in its own name as trustee of an express trust, and any
recovery of judgment shall, after provision for the payment of the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel, be for the ratable benefit of the Holders of the Securities and
coupons in respect of which such judgment has been recovered.

      SECTION 506. Application of Money Collected. Any money collected by the
Trustee pursuant to this Article shall be applied in the following order, at the
date or dates fixed by the Trustee and, in case of the distribution of such
money on account of principal (or premium or Make-Whole Amount, if any) or
interest, upon presentation of the Securities or coupons, or both, as the case
may be, and the notation thereon of the payment if only partially paid and upon
surrender thereof if fully paid:

            FIRST: To the payment of all amounts due the Trustee and any 
      predecessor Trustee under Section 606;


                                       43
<PAGE>   51
            SECOND: To the payment of the amounts then due and unpaid upon the
      Securities and coupons for principal (and premium or Make-Whole Amount, if
      any) and interest, in respect of which or for the benefit of which such
      money has been collected, ratably, without preference or priority of any
      kind, according to the aggregate amounts due and payable on such
      Securities and coupons for principal (and premium or Make-Whole Amount, if
      any) and interest, respectively; and

            THIRD: To the payment of the remainder, if any, to the Company.

      SECTION 507. Limitation on Suits. No Holder of any Security of any series
or any related coupon shall have any right to institute any proceeding, judicial
or otherwise, with respect to this Indenture, or for the appointment of a
receiver or trustee, or for any other remedy hereunder, unless:

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

                  (2) the Holders of not less than 25% in principal amount of
      the Outstanding Securities of that series shall have made written request
      to the Trustee to institute proceedings in respect of such Event of
      Default in its own name as Trustee hereunder;

                  (3) such Holder or Holders have offered to the Trustee
      indemnity reasonably satisfactory to the Trustee against the costs,
      expenses and liabilities to be incurred in compliance with such request;

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

                  (5) no direction inconsistent with such written request has
      been given to the Trustee during such 60-day period by the Holders of a
      majority in principal amount of the Outstanding Securities of that series;

it being understood and intended that no one or more of such Holders shall have
any right in any manner whatever by virtue of, or by availing of, any provision
of this Indenture to affect, disturb or prejudice the rights of any other of
such Holders, or to obtain or to seek to obtain priority or preference over any
other of such Holders or to enforce any right under this Indenture, except in
the manner herein provided and for the equal and ratable benefit of all such
Holders.

      SECTION 508. Unconditional Right of Holders to Receive Principal, Premium
or Make-Whole Amount, if any, and Interest. Notwithstanding any other provision
in this Indenture, the Holder of any Security or coupon shall have the right
which is absolute and unconditional to receive payment of the principal of (and
premium or Make-Whole Amount, if


                                       44
<PAGE>   52
any) and (subject to Sections 305 and 307) interest on such Security or payment
of such coupon on the respective due dates expressed in such Security or coupon
(or, in the case of redemption, on the Redemption Date) and to institute suit
for the enforcement of any such payment, and such rights shall not be impaired
without the consent of such Holder.

      SECTION 509. Restoration of Rights and Remedies. If the Trustee or any
Holder of a Security or coupon has instituted any proceeding to enforce any
right or remedy under this Indenture and such proceeding has been discontinued
or abandoned for any reason, or has been determined adversely to the Trustee or
to such Holder, then and in every such case, the Company, the Trustee and the
Holders of Securities and coupons shall, subject to any determination in such
proceeding, be restored severally and respectively to their former positions
hereunder and thereafter all rights and remedies of the Trustee and the Holders
shall continue as though no such proceeding had been instituted.

      SECTION 510. Rights and Remedies Cumulative. Except as otherwise provided
with respect to the replacement or payment of mutilated, destroyed, lost or
stolen Securities or coupons in the last paragraph of Section 306, no right or
remedy herein conferred upon or reserved to the Trustee or to the Holders of
Securities or coupons is intended to be exclusive of any other right or remedy,
and every right and remedy shall, to the extent permitted by law, be cumulative
and in addition to every other right and remedy given hereunder or now or
hereafter existing at law or in equity or otherwise. The assertion or employment
of any right or remedy hereunder, or otherwise, shall not prevent the concurrent
assertion or employment of any other appropriate right or remedy.

      SECTION 511. Delay or Omission Not Waiver. No delay or omission of the
Trustee or of any Holder of any Security or coupon to exercise any right or
remedy accruing upon any Event of Default shall impair any such right or remedy
or constitute a waiver of any such Event of Default or an acquiescence therein.
Every right and remedy given by this Article or by law to the Trustee or to the
Holders may be exercised from time to time, and as often as may be deemed
expedient, by the Trustee or by the Holders of Securities or coupons, as the
case may be.

      SECTION 512. Control by Holders of Securities. The Holders of not less
than a majority in principal amount of the Outstanding Securities of any series
shall have the right to direct the time, method and place of conducting any
proceeding for any remedy available to the Trustee or exercising any trust or
power conferred on the Trustee with respect to the Securities of such series,
provided that

                  (1) such direction shall not be in conflict with any rule of 
      law or with this Indenture,

                  (2) the Trustee may take any other action deemed proper by the
      Trustee which is not inconsistent with such direction, and


                                       45
<PAGE>   53
                  (3) the Trustee need not take any action which might involve
      it in personal liability or be unduly prejudicial to the Holders of
      Securities of such series not joining therein.

      Nothing in this Indenture shall impair the right of the Trustee in its
discretion to take any action deemed proper by the Trustee and which is not
inconsistent with such direction by Holders.

      SECTION 513. Waiver of Past Defaults. The Holders of not less than a
majority in principal amount of the Outstanding Securities of any series may on
behalf of the Holders of all the Securities of such series and any related
coupons waive any past default hereunder with respect to such series and its
consequences, except a default

                  (1) in the payment of the principal of (or premium or 
      Make-Whole Amount, if any) or interest on any Security of such series or 
      any related coupons, or

                  (2) in respect of a covenant or provision hereof which under
      Article Nine cannot be modified or amended without the consent of the
      Holder of each Outstanding Security of such series affected.

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

      SECTION 514. Waiver of Usury, Stay or Extension Laws. The Company
covenants (to the extent that it may lawfully do so) that it will not at any
time insist upon, or plead, or in any manner whatsoever claim or take the
benefit or advantage of, any usury, stay or extension law wherever enacted, now
or at any time hereafter in force, which may affect the covenants or the
performance of this Indenture; and the Company (to the extent that it may
lawfully do so) hereby expressly waives all benefit or advantage of any such
law, and covenants that it will not hinder, delay or impede the execution of any
power herein granted to the Trustee, but will suffer and permit the execution of
every such power as though no such law had been enacted.

      SECTION 515. Undertaking for Costs. All parties to this Indenture agree,
and each Holder of any Security by his acceptance thereof shall be deemed to
have agreed, that any court may in its discretion require, in any suit for the
enforcement of any right or remedy under this Indenture, or in any suit against
the Trustee for any action taken or omitted by it as Trustee, the filing by any
party litigant in such suit of an undertaking to pay the costs of such suit, and
that such court may in its discretion assess reasonable costs, including
reasonable attorneys' fees, against any party litigant in such suit having due
regard to the merits and good faith of the claims or defenses made by such party
litigant; but the provisions of this Section shall not apply to any suit
instituted by the Trustee, to any suit instituted by any Holder, or group of
Holders, holding in the aggregate more than 10% in principal amount of the


                                       46
<PAGE>   54
Outstanding Securities of any series, or to any suit instituted by any Holder
for the enforcement of the payment of the principal of (or premium or Make-Whole
Amount, if any) or interest on any Security on or after the respective Stated
Maturities expressed in such Security (or, in the case of redemption, on or
after the Redemption Date).


                            ARTICLE SIX - THE TRUSTEE

      SECTION 601. Notice of Defaults. Within 90 days after the occurrence of
any default hereunder with respect to the Securities of any series, the Trustee
shall transmit in the manner and to the extent provided in TIA Section 313(c),
notice of such default hereunder known to the Trustee, unless such default shall
have been cured or waived; provided, however, that, except in the case of a
default in the payment of the principal of (or premium or Make-Whole Amount, if
any) or interest on any Security of such series, or in the payment of any
sinking or purchase fund installment with respect to the Securities of such
series, the Trustee shall be protected in withholding such notice if and so long
as the board of directors, the executive committee, or a trust committee of
directors and/or Responsible Officers of the Trustee in good faith determine
that the withholding of such notice is in the interests of the Holders of the
Securities and coupons of such series; and provided further that in the case of
any default or breach of the character specified in Section 501(4) with respect
to the Securities and coupons of such series, no such notice to Holders shall be
given until at least 60 days after the occurrence thereof. For the purpose of
this Section, the term "default" means any event which is, or after notice or
lapse of time or both would become, an Event of Default with respect to the
Securities of such series.

      SECTION 602. Certain Rights of Trustee.  Subject to the provisions of TIA
Section 315(a) through 315(d):

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

                  (2) any request or direction of the Company mentioned herein
      shall be sufficiently evidenced by a Company Request or Company Order
      (other than delivery of any Security, together with any coupons
      appertaining thereto, to the Trustee for authentication and delivery
      pursuant to Section 303 which shall be sufficiently evidenced as provided
      therein) and any resolution of the Board of Directors may be sufficiently
      evidenced by a Board Resolution;

                  (3) whenever in the administration of this Indenture the
      Trustee shall deem it desirable that a matter be proved or established
      prior to taking, suffering or omitting any action hereunder, the Trustee
      (unless other evidence be herein specifically


                                       47
<PAGE>   55
      prescribed) may, in the absence of bad faith on its part, rely upon an
      Officers' Certificate;

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

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

                  (6) the Trustee shall not be bound to make any investigation
      into the facts or matters stated in any resolution, certificate,
      statement, instrument, opinion, report, notice, request, direction,
      consent, order, bond, debenture, note, coupon or other paper or document,
      unless requested in writing so to do by the Holders of not less than a
      majority in aggregate principal amount of the Outstanding Securities of
      any series; provided that, if the payment within a reasonable time to the
      Trustee of the costs, expenses or liabilities likely to be incurred by it
      in the making of such investigation is, in the opinion of the Trustee, not
      reasonably assured to the Trustee by the security afforded to it by the
      terms of this Indenture, the Trustee may require reasonable indemnity
      against such expenses or liabilities as a condition to proceeding; the
      reasonable expenses of every such examination shall be paid by the Holders
      or, if paid by the Trustee, shall be repaid by the Holders upon demand.
      The Trustee, in its discretion, may make such further inquiry or
      investigation into such facts or matters as it may see fit, and, if the
      Trustee shall determine to make such further inquiry or investigation, it
      shall be entitled to examine the books, records and premises of the
      Company, relevant to the facts or matters that are the subject of its
      inquiry, personally or by agent or attorney;

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

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

      The Trustee shall not be required to expend or risk its own funds or
otherwise incur any financial liability in the performance of any of its duties
hereunder, or in the exercise of


                                       48
<PAGE>   56
any of its rights or powers, if it shall have reasonable grounds for believing
that repayment of such funds or adequate indemnity against such risk or
liability is not reasonably assured to it.

      Except during the continuance of an Event of Default, the Trustee
undertakes to perform only such duties as are specifically set forth in this
Indenture, and no implied covenants or obligations shall be read into this
Indenture against the Trustee.

      SECTION 603. Not Responsible for Recitals or Issuance of Securities. The
recitals contained herein and in the Securities, except the Trustee's
certificate of authentication, and in any coupons shall be taken as the
statements of the Company, and neither the Trustee nor any Authenticating Agent
assumes any responsibility for their correctness. The Trustee makes no
representations as to the validity or sufficiency of this Indenture or of the
Securities or coupons, except that the Trustee represents that it is duly
authorized to execute and deliver this Indenture, authenticate the Securities
and perform its obligations hereunder. Neither the Trustee nor any
Authenticating Agent shall be accountable for the use or application by the
Company of Securities or the proceeds thereof.

      SECTION 604. May Hold Securities. The Trustee, any Paying Agent, Security
Registrar, Authenticating Agent or any other agent of the Company, in its
individual or any other capacity, may become the owner or pledgee of Securities
and coupons and, subject to TIA Sections 310(b) and 311, may otherwise deal with
the Company with the same rights it would have if it were not Trustee, Paying
Agent, Security Registrar, Authenticating Agent or such other agent.

      SECTION 605. Money Held in Trust. Money held by the Trustee in trust
hereunder need not be segregated from other funds except to the extent required
by law. The Trustee shall be under no liability for interest on any money
received by it hereunder except as otherwise agreed with the Company.

      SECTION 606. Compensation and Reimbursement.  The Company agrees:

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

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

                  (3) to indemnify each of the Trustee and any predecessor
      Trustee for, and to hold it harmless against, any loss, liability or
      expense incurred without


                                       49
<PAGE>   57
      negligence or bad faith on its part, arising out of or in connection with
      the acceptance or administration of the trust or trusts hereunder,
      including the costs and expenses of defending itself against any claim or
      liability in connection with the exercise or performance of any of its
      powers or duties hereunder.

      When the Trustee incurs expenses or renders services in connection with an
Event of Default specified in Section 501(7) or Section 501(8), the expenses
(including the reasonable charges and expenses of its counsel) and the
compensation for the services are intended to constitute expenses of
administration under any applicable Federal or state bankruptcy, insolvency or
other similar law.

      As security for the performance of the obligations of the Company under
this Section, the Trustee shall have a lien prior to the Securities upon all
property and funds held or collected by the Trustee as such, except funds held
in trust for the payment of principal of (or premium or Make-Whole Amount, if
any) or interest on particular Securities or any coupons.

      The provisions of this Section shall survive the termination of this
Indenture.

      SECTION 607. Corporate Trustee Required; Eligibility; Conflicting
Interests. There shall at all times be a Trustee hereunder which shall be
eligible to act as Trustee under TIA Section 310(a)(1) and shall have at all
times a combined capital and surplus of at least $50,000,000. If the Trustee
publishes reports of condition at least annually, pursuant to law or the
requirements of Federal, state, territorial or District of Columbia supervising
or examining authority, then for the purposes of this Section, the combined
capital and surplus of the Trustee shall be deemed to be its combined capital
and surplus as set forth in its most recent report of condition so published. If
at any time the Trustee shall cease to be eligible in accordance with the
provisions of this Section, it shall resign immediately in the manner and with
the effect hereinafter specified in this Article. Neither the Company nor any
Person directly or indirectly controlling, controlled by, or under common
control with the Company shall serve as Trustee.

      SECTION 608. Resignation and Removal; Appointment of Successor.

            (a) No resignation or removal of the Trustee and no appointment of a
successor Trustee pursuant to this Article shall become effective until the
acceptance of appointment by the successor Trustee in accordance with the
applicable requirements of Section 609.

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


                                       50
<PAGE>   58
            (c) The Trustee may be removed at any time with respect to the
Securities of any series by Act of the Holders of a majority in principal amount
of the Outstanding Securities of such series delivered to the Trustee and to the
Company.

            (d) If at any time:

                  (1) the Trustee shall fail to comply with the provisions of
      TIA Section 310(b) after written request therefor by the Company or by any
      Holder of a Security who has been a bona fide Holder of a Security for at
      least six months, or

                  (2) the Trustee shall cease to be eligible under Section 607
      and shall fail to resign after written request therefor by the Company or
      by any Holder of a Security who has been a bona fide Holder of a Security
      for at least six months, or

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

then, in any such case, (i) the Company by or pursuant to a Board Resolution may
remove the Trustee and appoint a successor Trustee with respect to all
Securities, or (ii) subject to TIA Section 315(e), any Holder of a Security who
has been a bona fide Holder of a Security for at least six months may, on behalf
of himself and all others similarly situated, petition any court of competent
jurisdiction for the removal of the Trustee with respect to all Securities and
the appointment of a successor Trustee or Trustees.

            (e) If the Trustee shall resign, be removed or become incapable of
acting, or if a vacancy shall occur in the office of Trustee for any cause with
respect to the Securities of one or more series, the Company, by or pursuant to
a Board Resolution, shall promptly appoint a successor Trustee or Trustees with
respect to the Securities of that or those series (it being understood that any
such successor Trustee may be appointed with respect to the Securities of one or
more or all of such series and that at any time there shall be only one Trustee
with respect to the Securities of any particular series). If, within one year
after such resignation, removal or incapability, or the occurrence of such
vacancy, a successor Trustee with respect to the Securities of any series shall
be appointed by Act of the Holders of a majority in principal amount of the
Outstanding Securities of such series delivered to the Company and the retiring
Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance
of such appointment, become the successor Trustee with respect to the Securities
of such series and to that extent supersede the successor Trustee appointed by
the Company. If no successor Trustee with respect to the Securities of any
series shall have been so appointed by the Company or the Holders of Securities
and accepted appointment in the manner hereinafter provided, any Holder of a
Security who has been a bona fide Holder of a Security of such series for at
least six months may, on behalf of himself and all others similarly


                                       51
<PAGE>   59
situated, petition any court of competent jurisdiction for the appointment of a
successor Trustee with respect to Securities of such series.

            (f) The Company shall give notice of each resignation and each
removal of the Trustee with respect to the Securities of any series and each
appointment of a successor Trustee with respect to the Securities of any series
in the manner provided for notices to the Holders of Securities in Section 106.
Each notice shall include the name of the successor Trustee with respect to the
Securities of such series and the address of its Corporate Trust Office.

      SECTION 609. Acceptance of Appointment by Successor. (a) In case of the
appointment hereunder of a successor Trustee with respect to all Securities,
every such successor Trustee so appointed shall execute, acknowledge and deliver
to the Company and to the retiring Trustee an instrument accepting such
appointment, and thereupon the resignation or removal of the retiring Trustee
shall become effective and such successor Trustee, without any further act, deed
or conveyance, shall become vested with all the rights, powers, trusts and
duties of the retiring Trustee; but, on request of the Company or the successor
Trustee, such retiring Trustee shall, upon payment of its charges, execute and
deliver an instrument transferring to such successor Trustee all the rights,
powers and trusts of the retiring Trustee, and shall duly assign, transfer and
deliver to such successor Trustee all property and money held by such retiring
Trustee hereunder, subject nevertheless to its claim, if any, provided for in
Section 606.

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


                                       52
<PAGE>   60
series to which the appointment of such successor Trustee relates; but, on
request of the Company or any successor Trustee, such retiring Trustee shall
duly assign, transfer and deliver to such successor Trustee all property and
money held by such retiring Trustee hereunder with respect to the Securities of
that or those series to which the appointment of such successor Trustee relates.

            (c) Upon request of any such successor Trustee, the Company shall
execute any and all instruments for more fully and certainly vesting in and
confirming to such successor Trustee all such rights, powers and trusts referred
to in paragraph (a) or (b) of this Section 609, as the case may be.

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

      SECTION 610. Merger, Conversion, Consolidation or Succession to Business.
Any corporation into which the Trustee may be merged or converted or with which
it may be consolidated, or any corporation resulting from any merger, conversion
or consolidation to which the Trustee shall be a party, or any corporation
succeeding to all or substantially all of the corporate trust business of the
Trustee, shall be the successor of the Trustee hereunder, provided such
corporation shall be otherwise qualified and eligible under this Article,
without the execution or filing of any paper or any further act on the part of
any of the parties hereto. In case any Securities or coupons shall have been
authenticated, but not delivered, by the Trustee then in office, any successor
by merger, conversion or consolidation to such authenticating Trustee may adopt
such authentication and deliver the Securities or coupons so authenticated with
the same effect as if such successor Trustee had itself authenticated such
Securities or coupons. In case any Securities or coupons shall not have been
authenticated by such predecessor Trustee, any such successor Trustee may
authenticate and deliver such Securities or coupons, in either its own name or
that of its predecessor Trustee, with the full force and effect which this
Indenture provides for the certificate of authentication of the Trustee.

      SECTION 611. Appointment of Authenticating Agent. At any time when any of
the Securities remain Outstanding, the Trustee may appoint an Authenticating
Agent or Agents with respect to one or more series of Securities which shall be
authorized to act on behalf of the Trustee to authenticate Securities of such
series issued upon exchange, registration of transfer or partial redemption or
repayment thereof, and Securities so authenticated shall be entitled to the
benefits of this Indenture and shall be valid and obligatory for all purposes as
if authenticated by the Trustee hereunder. Any such appointment shall be
evidenced by an instrument in writing signed by a Responsible Officer of the
Trustee, a copy of which instrument shall be promptly furnished to the Company.
Wherever reference is made in this Indenture to the authentication and delivery
of Securities by the Trustee or the Trustee's certificate of authentication,
such reference shall be deemed to include authentication and delivery on behalf
of the Trustee by an Authenticating Agent and a certificate of authentication
executed on behalf of the Trustee by an Authenticating Agent. Each
Authenticating Agent


                                       53
<PAGE>   61
shall be acceptable to the Company and shall at all times be a bank or trust
company or corporation organized and doing business and in good standing under
the laws of the United States of America or of any state or the District of
Columbia, authorized under such laws to act as Authenticating Agent, having a
combined capital and surplus of not less than $50,000,000 and subject to
supervision or examination by Federal or state authorities. If such
Authenticating Agent publishes reports of condition at least annually, pursuant
to law or the requirements of the aforesaid supervising or examining authority,
then for the purposes of this Section, the combined capital and surplus of such
Authenticating Agent shall be deemed to be its combined capital and surplus as
set forth in its most recent report of condition so published. In case at any
time an Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, such Authenticating Agent shall resign immediately
in the manner and with the effect specified in this Section.

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

         An Authenticating Agent for any series of Securities may at any time
resign by giving written notice of resignation to the Trustee for such series
and to the Company. The Trustee for any series of Securities may at any time
terminate the agency of an Authenticating Agent by giving written notice of
termination to such Authenticating Agent and to the Company. Upon receiving such
a notice of resignation or upon such a termination, or in case at any time such
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, the Trustee for such series may appoint a successor
Authenticating Agent which shall be acceptable to the Company and shall give
notice of such appointment to all Holders of Securities of the series with
respect to which such Authenticating Agent will serve in the manner set forth in
Section 106. Any successor Authenticating Agent upon acceptance of its
appointment hereunder shall become vested with all the rights, powers and duties
of its predecessor hereunder, with like effect as if originally named as an
Authenticating Agent herein. No successor Authenticating Agent shall be
appointed unless eligible under the provisions of this Section.

         The Company agrees to pay to each Authenticating Agent from time to
time reasonable compensation including reimbursement of its reasonable expenses
for its services under this Section.

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


                                       54
<PAGE>   62
         This is one of the Securities of the series designated therein referred
to in the within-mentioned Indenture.

                                             [                 ]
                                                      as Trustee

Dated: ____________                          By:________________________________
                                                      as Authenticating Agent


Dated: ____________                          By:________________________________
                                                      as Authenticating Agent

         SECTION 612. Certain Duties and Responsibilities of the Trustee.

         (a) With respect to the Securities of any series, except during the
continuance of an Event of Default with respect to the Securities of such
series:

                  (1) the Trustee undertakes to perform such duties and only
         such duties as are specifically set forth in this Indenture, and no
         implied covenants or obligations shall be read into this Indenture
         against the Trustee; and

                  (2) in the absence of bad faith on its part, the Trustee may
         conclusively rely, as to the truth of the statements and the
         correctness of the opinions expressed therein, upon certificates or
         opinions furnished to the Trustee and conforming to the requirements of
         this Indenture; but in the case of any such certificates or opinions
         which by any provision hereof are specifically required to be furnished
         to the Trustee, the Trustee shall be under a duty to examine the same
         to determine whether or not they conform to the requirements of this
         Indenture, but shall not be under any duty to verify the contents or
         accuracy thereof.

         (b) In case an Event of Default with respect to the Securities of any
series has occurred and is continuing, the Trustee shall, with respect to
Securities of such series, exercise such of the rights and powers vested in it
by this Indenture, and use the same degree of care and skill in their exercise,
as a prudent man would exercise or use under the circumstances in the conduct of
his own affairs.

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

                  (1) this Subsection shall not be construed to limit the effect
         of Subsection (a) of this Section;


                                       55
<PAGE>   63
                  (2) the Trustee shall not be liable for any error of judgment
         made in good faith by a Responsible Officer, unless it shall be proved
         that the Trustee was negligent in ascertaining the pertinent facts;

                  (3) the Trustee shall not be liable with respect to any action
         taken or omitted to be taken by it in good faith in accordance with the
         direction of the Holders of a majority in principal amount of the
         Outstanding Securities of any series relating to the time, method and
         place of conducting any proceeding for any remedy available to the
         Trustee, or exercising any trust or power conferred upon the Trustee,
         under this Indenture with respect to the Securities of such series; and

                  (4) no provision of this Indenture shall require the Trustee
         to expend or risk its own funds or otherwise incur any financial
         liability in the performance of any of its duties hereunder, or in the
         exercise of any of its rights or powers, if it shall have reasonable
         grounds for believing that repayment of such funds or adequate
         indemnity against such risk or liability is not reasonably assured to
         it.

         (d) Whether or not therein expressly so provided, every provision of
this Indenture relating to the conduct or affecting the liability of or
affording protection to the Trustee shall be subject to the provisions of this
Section 612.

        ARTICLE SEVEN - HOLDERS' LISTS AND REPORTS BY TRUSTEE AND COMPANY

         SECTION 701. Disclosure of Names and Addresses of Holders. Every Holder
of Securities or coupons, by receiving and holding the same, agrees with the
Company and the Trustee that neither the Company nor the Trustee nor any
Authenticating Agent nor any Paying Agent nor any Security Registrar shall be
held accountable by reason of the disclosure of any information as to the names
and addresses of the Holders of Securities in accordance with TIA Section 312,
regardless of the source from which such information was derived, and that the
Trustee shall not be held accountable by reason of mailing any material pursuant
to a request made under TIA Section 312(b).

         SECTION 702. Reports by Trustee. The Trustee shall transmit to Holders
such reports concerning the Trustee and its actions under this Indenture as may
be required by TIA Section 313 at the times and in the manner provided by the
TIA, which shall initially be not less than every twelve months commencing on
[_________________], 199_. A copy of each such report shall, at the time of such
transmission to Holders, be filed by the Trustee with each stock exchange, if
any, upon which any Securities are listed, with the Commission and with the
Company. The Company will notify the Trustee when any Securities are listed on
any stock exchange.

         SECTION 703. Reports by Company. The Company will:

                  (1) file with the Trustee, within 15 days after the Company is
         required to file the same with the Commission, copies of the annual
         reports and of the information, documents and other reports (or copies
         of such portions of any of the foregoing as the Commission may from
         time to time by rules and regulations prescribe) which the Company may
         be required to file with the Commission pursuant to Section 13 or
         Section 15(d) of the Securities Exchange Act of 1934; or, if the
         Company is not required to file information, documents or reports
         pursuant to either of such Sections, then it will file with the Trustee
         and the Commission, in accordance with rules and regulations prescribed
         from time to time by the Commission, such of the supplementary and
         periodic information, documents and reports which may be required
         pursuant to Section 13 of the Securities Exchange Act of 1934 in

         exchange as may be prescribed from time to time in such rules and
         regulations;

                  (2) file with the Trustee and the Commission, in accordance
         with rules and regulations prescribed from time to time by the
         Commission, such additional information, documents and reports with
         respect to compliance by the Company with the conditions and covenants
         of this Indenture as may be required from time to time by such rules
         and regulations; and

                  (3) transmit by mail to the Holders of Securities, within 30
         days after the filing thereof with the Trustee, in the manner and to

         pursuant to paragraphs (1) and (2) of this Section as may be required

The Company will furnish or cause to be furnished to the Trustee:

             (a) semiannually, not later than 15 days after the Regular Record
Date for interest for each series of Securities, a list, in such form as the
Trustee may reasonably require, of the names and addresses of the Holders of
Registered Securities of such series as of such Regular Record Date, or if there
is no Regular Record Date for interest for such series of Securities,
semiannually, upon such dates as are set forth in the Board Resolution or
indenture supplemental hereto authorizing such series, and

             (b) at such other times as the Trustee may request in writing,
within 30 days after the receipt by the Company of any such request, a list of
similar form and content as of a date not more than 15 days prior to the time
such list is furnished,

provided, however, that, so long as the Trustee is the Security Registrar, no
such list shall be required to be furnished.

        ARTICLE EIGHT - CONSOLIDATION, MERGER, SALE, LEASE OR CONVEYANCE

         SECTION 801. Consolidations and Mergers of Company and Sales, Leases
and Conveyances Permitted Subject to Certain Conditions. The Company may
consolidate with, or sell, lease or convey all or substantially all of its
assets to, or merge with or into any other corporation, provided that in any
such case, (1) either the Company shall be the continuing corporation, or the
successor corporation shall be a corporation organized and existing under the
laws of the United States or a State thereof and such successor corporation
shall expressly assume the due and punctual payment of the principal of (and
premium or Make-Whole Amount, if any) and any interest on all of the Securities,
according to their tenor, and the due and punctual performance and observance of
all of the covenants and conditions of this Indenture to be performed by the
Company by supplemental indenture, complying with Article Nine hereof,
satisfactory to the Trustee, executed and delivered to the Trustee by such
corporation and (2) immediately after giving effect to such transaction and
treating any indebtedness which becomes an obligation of the Company or any
Subsidiary as a result thereof as having been incurred by the Company or such
Subsidiary at the time of such transaction, no Event of Default, and no event
which, after notice or the lapse of time, or both, would become an Event of
Default, shall have occurred and be continuing.

         SECTION 802. Rights and Duties of Successor Corporation. In case of any
such consolidation, merger, sale, lease or conveyance and upon any such
assumption by the successor corporation, such successor corporation shall
succeed to and be substituted for the Company, with the same effect as if it had
been named herein as the party of the first part, and the predecessor
corporation, except in the event of a lease, shall be relieved of any further
obligation under this Indenture and the Securities. Such successor corporation
thereupon may cause to be signed, and may issue either in its own name or in the
name of the Company, any or all of the Securities issuable hereunder which
theretofore shall not have been signed by the Company and delivered to the
Trustee; and, upon the order of such successor corporation, instead of the
Company, and subject to all the terms, conditions and limitations in this
Indenture prescribed, the Trustee shall authenticate and shall deliver any
Securities which previously shall have been signed and delivered by the officers
of the Company to the Trustee for authentication, and any Securities which such
successor corporation thereafter shall cause to be signed and delivered to the
Trustee for that purpose. All the Securities so issued shall in all respects
have the same legal rank and benefit under this Indenture as the Securities
theretofore or thereafter issued in accordance with the terms of this Indenture
as though all of such Securities had been issued at the date of the execution
hereof.

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

         SECTION 803. Officers' Certificate and Opinion of Counsel. Any
consolidation, merger, sale, lease or conveyance permitted under Section 801 is
also subject to the condition that the Trustee receive an Officers' Certificate
and an Opinion of Counsel to the effect that


                                       58
<PAGE>   66
any such consolidation, merger, sale, lease or conveyance, and the assumption by
any successor corporation, complies with the provisions of this Article and that
all conditions precedent herein provided for relating to such transaction have
been complied with.


                     ARTICLE NINE - SUPPLEMENTAL INDENTURES

         SECTION 901. Supplemental Indentures Without Consent of Holders.
Without the consent of any Holders of Securities or coupons, the Company, when
authorized by or pursuant to a Board Resolution, and the Trustee, at any time
and from time to time, may enter into one or more indentures supplemental
hereto, in form satisfactory to the Trustee, for any of the following purposes:

                  (1) to evidence the succession of another Person to the
         Company and the assumption by any such successor of the covenants of
         the Company contained herein and in the Securities; or

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

                  (3) to add any additional Events of Default for the benefit of
         the Holders of all or any series of Securities (and if such Events of
         Default are to be for the benefit of less than all series of
         Securities, stating that such Events of Default are expressly being
         included solely for the benefit of such series); provided, however,
         that in respect of any such additional Events of Default such
         supplemental indenture may provide for a particular period of grace
         after default (which period may be shorter or longer than that allowed
         in the case of other defaults) or may provide for an immediate
         enforcement upon such default or may limit the remedies available to
         the Trustee upon such default or may limit the right of the Holders of
         a majority in aggregate principal amount of that or those series of
         Securities to which such additional Events of Default apply to waive
         such default; or

                  (4) to add to or change any of the provisions of this
         Indenture to provide that Bearer Securities may be registrable as to
         principal, to change or eliminate any restrictions on the payment of
         principal of or premium or Make-Whole Amount, if any, or interest on
         Bearer Securities, to permit Bearer Securities to be issued in exchange
         for Registered Securities, to permit Bearer Securities to be issued in
         exchange for Bearer Securities of other authorized denominations or to
         permit or facilitate the issuance of Securities in uncertificated form,
         provided that any such action shall not adversely affect the interests
         of the Holders of Securities of any series or any related coupons in
         any material respect; or


                                       59
<PAGE>   67
                  (5) to change or eliminate any of the provisions of this
         Indenture, provided that any such change or elimination shall become
         effective only when there is no Security Outstanding of any series
         created prior to the execution of such supplemental indenture which is
         entitled to the benefit of such provision; or

                  (6) to secure the Securities; or

                  (7) to establish the form or terms of Securities of any series
         and any related coupons as permitted by Sections 201 and 301; or

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

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

                  (10) to supplement any of the provisions of this Indenture to
         such extent as shall be necessary to permit or facilitate the
         defeasance and discharge of any series of Securities pursuant to
         Sections 401, 1402 and 1403; provided that any such action shall not
         adversely affect the interests of the Holders of Securities of such
         series and any related coupons or any other series of Securities in any
         material respect; or

                  (11) to make provisions with respect to Holders' rights of
         conversion with respect to any series of Securities pursuant to
         Articles Seventeen.

         SECTION 902. Supplemental Indentures with Consent of Holders. With the
consent of the Holders of not less than a majority in principal amount of all
Outstanding Securities affected by such supplemental indenture, by Act of said
Holders delivered to the Company and the Trustee, the Company, when authorized
by or pursuant to a Board Resolution, and the Trustee may enter into an
indenture or indentures supplemental hereto for the purpose of adding any
provisions to or changing in any manner or eliminating any of the provisions of
this Indenture or of modifying in any manner the rights of the Holders of
Securities and any related coupons under this Indenture; provided, however, that
no such supplemental indenture shall, without the consent of the Holder of each
Outstanding Security affected thereby:

                  (1) change the Stated Maturity of the principal of (or premium
         or Make-Whole Amount, if any, on) or any installment of principal of or
         interest on, any


                                       60
<PAGE>   68
         Security; or reduce the principal amount thereof or the rate or amount
         of interest thereon, or any premium or Make-Whole Amount payable upon
         the redemption thereof, or reduce the amount of the principal of an
         Original Issue Discount Security that would be due and payable upon a
         declaration of acceleration of the Maturity thereof pursuant to Section
         502 or the amount thereof provable in bankruptcy pursuant to Section
         504, or adversely affect any right of repayment at the option of the
         Holder of any Security, or change any Place of Payment where, or the
         currency or currencies, currency unit or units or composite currency or
         currencies in which, any Security or any premium or Make-Whole Amount
         or the interest thereon is payable, or impair the right to institute
         suit for the enforcement of any such payment on or after the Stated
         Maturity thereof (or, in the case of redemption or repayment at the
         option of the Holder, on or after the Redemption Date or the Repayment
         Date, as the case may be), or (if Securities of such series are
         convertible) adversely affect the right of the Holder to convert any
         Security as provided in Article Seventeen, or modify the provisions of
         this Indenture with respect to the subordination of the Securities in a
         manner materially adverse to the Holders; or

                  (2) reduce the percentage in principal amount of the
         Outstanding Securities of any series, the consent of whose Holders is
         required for any such supplemental indenture, or the consent of whose
         Holders is required for any waiver with respect to such series (or
         compliance with certain provisions of this Indenture or certain
         defaults hereunder and their consequences) provided for in this
         Indenture, or reduce the requirements of Section 1504 for quorum or
         voting, or

                  (3) modify any of the provisions of this Section, Section 513
         or Section 1009, except to increase the required percentage to effect
         such action or to provide that certain other provisions of this
         Indenture cannot be modified or waived without the consent of the
         Holder of each Outstanding Security affected thereby, provided,
         however, that this clause shall not be deemed to require the consent of
         any Holder with respect to changes in the references to "the Trustee"
         and concomitant changes in this Section 902 and Section 1009, or the
         deletion of this proviso, in accordance with the requirements of
         Sections 609(b) and 901(11).

         It shall not be necessary for any Act of Holders under this Section 902
to approve the particular form of any proposed supplemental indenture, but it
shall be sufficient if such Act shall approve the substance thereof.

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

<PAGE>   69
         SECTION 903. Execution of Supplemental Indentures. In executing, or
accepting the additional trusts created by, any supplemental indenture permitted
by this Article or the modification thereby of the trusts created by this
Indenture, the Trustee shall be entitled to receive, and shall be fully
protected in relying upon, an Opinion of Counsel stating that the execution of
such supplemental indenture is authorized or permitted by this Indenture. The
Trustee may, but shall not be obligated to, enter into any such supplemental
indenture which affects the Trustee's own rights, duties or immunities under
this Indenture or otherwise.

         SECTION 904. Effect of Supplemental Indentures. Upon the execution of
any supplemental indenture under this Article, this Indenture shall be modified
in accordance therewith, and such supplemental indenture shall form a part of
this Indenture for all purposes; and every Holder of Securities theretofore or
thereafter authenticated and delivered hereunder and of any coupon appertaining
thereto shall be bound thereby.

         SECTION 905. Conformity with Trust Indenture Act. Every supplemental
indenture executed pursuant to this Article shall conform to the requirements of
the Trust Indenture Act as then in effect.

         SECTION 906. Reference in Securities to Supplemental Indentures.
Securities of any series authenticated and delivered after the execution of any
supplemental indenture pursuant to this Article may, and shall, if required by
the Trustee, bear a notation in form approved by the Trustee as to any matter
provided for in such supplemental indenture. If the Company shall so determine,
new Securities of any series so modified as to conform, in the opinion of the
Trustee and the Company, to any such supplemental indenture may be prepared and
executed by the Company and authenticated and delivered by the Trustee in
exchange for Outstanding Securities of such series.


                             ARTICLE TEN - COVENANTS

         SECTION 1001. Payment of Principal, Premium or Make-Whole Amount, if
any; and Interest. The Company covenants and agrees for the benefit of the
Holders of each series of Securities that it will duly and punctually pay the
principal of (and premium or Make-Whole Amount, if any) and interest on the
Securities of that series in accordance with the terms of such series of
Securities, any coupons appertaining thereto and this Indenture. Unless
otherwise specified as contemplated by Section 301 with respect to any series of
Securities, any interest due on Bearer Securities on or before Maturity shall be
payable only upon presentation and surrender of the several coupons for such
interest installments as are evidenced thereby as they severally mature. Unless
otherwise specified with respect to Securities of any series pursuant to Section
301, at the option of the Company, all payments of principal may be paid by
check to the registered Holder of the Registered Security or other person
entitled thereto against surrender of such Security.


                                       62
<PAGE>   70
         SECTION 1002. Maintenance of Office or Agency. If Securities of a
series are issuable only as Registered Securities, the Company shall maintain in
each Place of Payment for any series of Securities an office or agency where
Securities of that series may be presented or surrendered for payment or
conversion, where Securities of that series may be surrendered for registration
of transfer or exchange and where notices and demands to or upon the Company in
respect of the Securities of that series and this Indenture may be served. If
Securities of a series are issuable as Bearer Securities, the Company will
maintain: (A) in the Borough of Manhattan, The City of New York, an office or
agency where any Registered Securities of that series may be presented or
surrendered for payment or conversion, where any Registered Securities of that
series may be surrendered for registration of transfer, where Securities of that
series may be surrendered for exchange, where notices and demands to or upon the
Company in respect of the Securities of that series and this Indenture may be
served and where Bearer Securities of that series and related coupons may be
presented or surrendered for payment or conversion in the circumstances
described in the following paragraph (and not otherwise); (B) subject to any
laws or regulations applicable thereto, in a Place of Payment for that series
which is located outside the United States, an office or agency where Securities
of that series and related coupons may be presented and surrendered for payment;
provided, however, that if the Securities of that series are listed on any stock
exchange located outside the United States and such stock exchange shall so
require, the Company will maintain a Paying Agent for the Securities of that
series in any required city located outside the United States, as the case may
be, so long as the Securities of that series are listed on such exchange; and
(C) subject to any laws or regulations applicable thereto, in a Place of Payment
for that series located outside the United States an office or agency where any
Registered Securities of that series may be surrendered for registration of
transfer, where Securities of that series may be surrendered for exchange and
where notices and demands to or upon the Company in respect of the Securities of
that series and this Indenture may be served. The Company will give prompt
written notice to the Trustee of the location, and any change in the location,
of each such office or agency. If at any time the Company shall fail to maintain
any such required office or agency or shall fail to furnish the Trustee with the
address thereof, such presentations, surrenders, notices and demands may be made
or served at the Corporate Trust Office of the Trustee, except that Bearer
Securities of that series and the related coupons may be presented and
surrendered for payment or conversion at the offices specified in the Security,
in London, England, and the Company hereby appoints the same as its agent to
receive such respective presentations, surrenders, notices and demands, and the
Company hereby appoints the Trustee its agent to receive all such presentations,
surrenders, notices and demands.

         Unless otherwise specified with respect to any Securities pursuant to
Section 301, no payment of principal, premium or Make-Whole Amount or interest
on Bearer Securities shall be made at any office or agency of the Company in the
United States or by check mailed to any address in the United States or by
transfer to an account maintained with a bank located in the United States;
provided, however, that, if the Securities of a series are payable in Dollars,
payment of principal of and any premium or Make-Whole Amount and interest on any
Bearer Security shall be made at the office of the Company's Paying Agent in the
Borough of Manhattan, The City of New York, if (but only if) payment in Dollars
of the full amount of


                                       63
<PAGE>   71
such principal, premium or Make-Whole Amount, or interest, as the case may be,
at all offices or agencies outside the United States maintained for the purpose
by the Company in accordance with this Indenture, is illegal or effectively
precluded by exchange controls or other similar restrictions.

         The Company may from time to time designate one or more other offices
or agencies where the Securities of one or more series may be presented or
surrendered for any or all of such purposes, and may from time to time rescind
such designations; provided, however, that no such designation or rescission
shall in any manner relieve the Company of its obligation to maintain an office
or agency in accordance with the requirements set forth above for Securities of
any series for such purposes. The Company will give prompt written notice to the
Trustee of any such designation or rescission and of any change in the location
of any such other office or agency. Unless otherwise specified with respect to
any Securities pursuant to Section 301 with respect to a series of Securities,
the Company hereby designates as a Place of Payment for each series of
Securities the office or agency of the Company in the Borough of Manhattan, The
City of New York, and initially appoints the Trustee at its Corporate Trust
Office as Paying Agent in such city and as its agent to receive all such
presentations, surrenders, notices and demands.

         Unless otherwise specified with respect to any Securities pursuant to
Section 301, if and so long as the Securities of any series (i) are denominated
in a Foreign Currency or (ii) may be payable in a Foreign Currency, or so long
as it is required under any other provision of the Indenture, then the Company
will maintain with respect to each such series of Securities, or as so required,
at least one exchange rate agent.

         SECTION 1003. Money for Securities Payments to Be Held in Trust. If the
Company shall at any time act as its own Paying Agent with respect to any series
of any Securities and any related coupons, it will, on or before each due date
of the principal of (and premium or Make-Whole Amount, if any), or interest on
any of the Securities of that series, segregate and hold in trust for the
benefit of the Persons entitled thereto a sum in the currency or currencies,
currency unit or units or composite currency or currencies in which the
Securities of such series are payable (except as otherwise specified pursuant to
Section 301 for the Securities of such series) sufficient to pay the principal
(and premium or Make-Whole Amount, if any) or interest so becoming due until
such sums shall be paid to such Persons or otherwise disposed of as herein
provided, and will promptly notify the Trustee of its action or failure so to
act.

         Whenever the Company shall have one or more Paying Agents for any
series of Securities and any related coupons, it will, on or before each due
date of the principal of (and premium or Make-Whole Amount, if any), or interest
on any Securities of that series, deposit with a Paying Agent a sum (in the
currency or currencies, currency unit or units or composite currency or
currencies described in the preceding paragraph) sufficient to pay the principal
(and premium or Make-Whole Amount, if any) or interest so becoming due, such sum
to be held in trust for the benefit of the Persons entitled to such principal,
premium or Make-Whole


                                       64
<PAGE>   72
Amount, if any, or interest and (unless such Paying Agent is the Trustee) the
Company will promptly notify the Trustee of its action or failure so to act.

         The Company will cause each Paying Agent for any series of Securities
other than the Trustee to execute and deliver to the Trustee an instrument in
which such Paying Agent shall agree with the Trustee, subject to the provisions
of this Section, that such Paying Agent will

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

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

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

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

         Except as otherwise provided in the Securities of any series, any money
deposited with the Trustee or any Paying Agent, or then held by the Company, in
trust for the payment of the principal of (and premium or Make-Whole Amount, if
any) or interest on any Security of any series and remaining unclaimed for two
years after such principal (and premium or Make-Whole Amount, if any) or
interest has become due and payable shall be paid to the Company upon Company
Request or (if then held by the Company) shall be discharged from such trust;
and the Holder of such Security shall thereafter, as an unsecured general
creditor, look only to the Company for payment of such principal of (and premium
or Make-Whole Amount, if any) or interest on any Security, without interest
thereon, and all liability of the Trustee or such Paying Agent with respect to
such trust money, and all liability of the Company as trustee thereof, shall
thereupon cease; provided, however, that the Trustee or such Paying Agent,
before being required to make any such repayment, may at the expense of the
Company cause to be published once, in an Authorized Newspaper, notice that such
money remains unclaimed and that, after a date specified therein, which shall
not be less than 30 days from the date of


                                       65
<PAGE>   73
such publication, any unclaimed balance of such money then remaining will be
repaid to the Company.

         SECTION 1004. Existence. Subject to Article Eight, the Company will do
or cause to be done all things necessary to preserve and keep in full force and
effect its corporate existence, all material rights (by articles of
incorporation, by-laws and statute) and material franchises; provided, however,
that the Company shall not be required to preserve any such right or franchise
if the Board of Directors shall determine that the preservation thereof is no
longer desirable in the conduct of the business of the Company.

         SECTION 1005. Maintenance of Properties. The Company will cause all of
its material properties used or useful in the conduct of its business or the
business of any Subsidiary to be maintained and kept in good condition, repair
and working order and supplied with all necessary equipment and will cause to be
made all necessary repairs, renewals, replacements, betterments and improvements
thereof, all as in the judgment of the Company may be necessary so that the
business carried on in connection therewith may be properly and advantageously
conducted at all times; provided, however, that the Company and its Subsidiaries
shall not be prevented from selling or otherwise disposing of their properties
for value in the ordinary course of business.

         SECTION 1006. Insurance. The Company will cause each of its and its
Subsidiaries' insurable properties to be insured against loss or damage in an
amount deemed reasonable by the Board of Directors with insurers of recognized
responsibility.

         SECTION 1007. Payment of Taxes and Other Claims. The Company will pay
or discharge or cause to be paid or discharged, before the same shall become
delinquent, (1) all taxes, assessments and governmental charges levied or
imposed upon it or any Subsidiary or upon the income, profits or property of the
Company or any Subsidiary, and (2) all lawful claims for labor, materials and
supplies which, if unpaid, might by law become a lien upon the property of the
Company or any Subsidiary; provided, however, that the Company shall not be
required to pay or discharge or cause to be paid or discharged any such tax,
assessment, charge or claim whose amount, applicability or validity is being
contested in good faith by appropriate proceedings.

         SECTION 1008. Statement as to Compliance. The Company will deliver to
the Trustee, within 120 days after the end of each fiscal year, a brief
certificate from the principal executive officer, principal financial officer or
principal accounting officer as to his or her knowledge of the Company's
compliance with all conditions and covenants under this Indenture and, in the
event of any noncompliance, specifying such noncompliance and the nature and
status thereof. For purposes of this Section 1008, such compliance shall be
determined without regard to any period of grace or requirement of notice under
this Indenture.

         SECTION 1009. Waiver of Certain Covenants. The Company may omit in any
particular instance to comply with any term, provision or condition set forth in
Sections 1004 to 1008, inclusive, if before or after the time for such
compliance the Holders of at least a majority in principal amount of all
outstanding Securities of such series, by Act of such Holders, either waive such
compliance in such instance or generally waive compliance with such covenant or
condition, but no such waiver shall extend to or affect such covenant or
condition except to the extent so expressly waived, and, until such waiver shall
become effective, the obligations of the Company and the duties of the Trustee
in respect of any such term, provision or condition shall remain in full force
and effect.


                    ARTICLE ELEVEN - REDEMPTION OF SECURITIES

         SECTION 1101. Applicability of Article. Securities of any series which
are redeemable before their Stated Maturity shall be redeemable in accordance
with their terms and (except as otherwise specified as contemplated by Section
301 for Securities of any series) in accordance with this Article.

         SECTION 1102. Election to Redeem; Notice to Trustee. The election of
the Company to redeem any Securities shall be evidenced by or pursuant to a
Board Resolution. In case of any redemption at the election of the Company of
less than all of the Securities of any series, the Company shall, at least 45
days prior to the giving of the notice of redemption in Section 1104 (unless a
shorter notice shall be satisfactory to the Trustee), notify the Trustee of such
Redemption Date and of the principal amount of Securities of such series to be
redeemed. In the case of any redemption of Securities prior to the expiration of
any restriction on such redemption provided in the terms of such Securities or
elsewhere in this Indenture, the Company shall furnish the Trustee with an
Officers' Certificate evidencing compliance with such restriction.

         SECTION 1103. Selection by Trustee of Securities to Be Redeemed. If
less than all the Securities of any series issued on the same day with the same
terms are to be redeemed, the particular Securities to be redeemed shall be
selected not more than 60 days prior to the Redemption Date by the Trustee, from
the Outstanding Securities of such series issued on such date with the same
terms not previously called for redemption, by such method as the Trustee shall
deem fair and appropriate and which may provide for the selection for redemption
of portions (equal to the minimum authorized denomination for Securities of that
series or any integral multiple thereof) of the principal amount of Securities
of such series of a denomination larger than the minimum authorized denomination
for Securities of that series.

         The Trustee shall promptly notify the Company and the Security
Registrar (if other than itself) in writing of the Securities selected for
redemption and, in the case of any Securities selected for partial redemption,
the principal amount thereof to be redeemed.


                                       67
<PAGE>   75
         For all purposes of this Indenture, unless the context otherwise
requires, all provisions relating to the redemption of Securities shall relate,
in the case of any Security redeemed or to be redeemed only in part, to the
portion of the principal amount of such Security which has been or is to be
redeemed.

         SECTION 1104. Notice of Redemption. Notice of redemption shall be given
in the manner provided in Section 106, not less than 30 days nor more than 60
days prior to the Redemption Date, unless a shorter period is specified by the
terms of such series established pursuant to Section 301, to each Holder of
Securities to be redeemed, but failure to give such notice in the manner herein
provided to the Holder of any Security designated for redemption as a whole or
in part, or any defect in the notice to any such Holder, shall not affect the
validity of the proceedings for the redemption of any other such Security or
portion thereof.

         Any notice that is mailed to the Holders of Registered Securities in
the manner herein provided shall be conclusively presumed to have been duly
given, whether or not the Holder receives the notice.

         All notices of redemption shall state:

                  (1) the Redemption Date,

                  (2) the Redemption Price, accrued interest to the Redemption
         Date payable as provided in Section 1106, if any,

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

                  (4) in case any Security is to be redeemed in part only, the
         notice which relates to such Security shall state that on and after the
         Redemption Date, upon surrender of such Security, the holder will
         receive, without a charge, a new Security or Securities of authorized
         denominations for the principal amount thereof remaining unredeemed,

                  (5) that on the Redemption Date the Redemption Price and
         accrued interest to the Redemption Date payable as provided in Section
         1106, if any, will become due and payable upon each such Security, or
         the portion thereof, to be redeemed and, if applicable, that interest
         thereon shall cease to accrue on and after said date,

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


                                       68
<PAGE>   76
                  (7) that the redemption is for a sinking fund, if such is the
         case,

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

                  (9) if Bearer Securities of any series are to be redeemed and
         any Registered Securities of such series are not to be redeemed, and if
         such Bearer Securities may be exchanged for Registered Securities not
         subject to redemption on this Redemption Date pursuant to Section 305
         or otherwise, the last date, as determined by the Company, on which
         such exchanges may be made,

                  (10) the CUSIP number of such Security, if any, and

                  (11) if applicable, that a Holder of Securities who desires to
         convert Securities for redemption must satisfy the requirements for
         conversion contained in such Securities, the then existing conversion
         price or rate, the place or places where such Securities may be
         surrendered for conversion, and the date and time when the option to
         convert shall expire.

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

         SECTION 1105. Deposit of Redemption Price. On or prior to any
Redemption Date, the Company shall deposit with the Trustee or with a Paying
Agent (or, if the Company is acting as its own Paying Agent, which it may not do
in the case of a sinking fund payment under Article Twelve, segregate and hold
in trust as provided in Section 1003) an amount of money in the currency or
currencies, currency unit or units or composite currency or currencies in which
the Securities of such series are payable (except as otherwise specified
pursuant to Section 301 for the Securities of such series) sufficient to pay on
the Redemption Date the Redemption Price of, and (except if the Redemption Date
shall be an Interest Payment Date) accrued interest on, all the Securities or
portions thereof which are to be redeemed on that date.

         If any Securities called for redemption are converted, any money
deposited with the Trustee or with any Paying Agent or so segregated and held in
trust for the redemption of such Security shall be paid to the Company upon
Company Request or, if then held by the Company, shall be discharged from such
trust.


                                       69
<PAGE>   77
         SECTION 1106. Securities Payable on Redemption Date. Notice of
redemption having been given as aforesaid, the Securities so to be redeemed
shall, on the Redemption Date, become due and payable at the Redemption Price
therein specified in the currency or currencies, currency unit or units or
composite currency or currencies in which the Securities of such series are
payable (except as otherwise specified pursuant to Section 301 for the
Securities of such series) (together with accrued interest, if any, to the
Redemption Date), and from and after such date (unless the Company shall default
in the payment of the Redemption Price and accrued interest) such Securities
shall, if the same were interest-bearing, cease to bear interest and the coupons
for such interest appertaining to any Bearer Securities so to be redeemed,
except to the extent provided below, shall be void. Upon surrender of any such
Security for redemption in accordance with said notice, together with all
coupons, if any, appertaining thereto maturing after the Redemption Date, such
Security shall be paid by the Company at the Redemption Price, together with
accrued interest, if any, to the Redemption Date; provided, however, that
installments of interest on Bearer Securities whose Stated Maturity is on or
prior to the Redemption Date shall be payable only at an office or agency
located outside the United States (except as otherwise provided in Section 1002)
and, unless otherwise specified as contemplated by Section 301, only upon
presentation and surrender of coupons for such interest; and provided further
that, except as otherwise provided with respect to Securities convertible into
the Company's Common Stock or Preferred Stock, installments of interest on
Registered Securities whose Stated Maturity is on or prior to the Redemption
Date shall be payable to the Holders of such Securities, or one or more
Predecessor Securities, registered as such at the close of business on the
relevant Record Dates according to their terms and the provisions of Section
307.

         If any Bearer Security surrendered for redemption shall not be
accompanied by all appurtenant coupons maturing after the Redemption Date, such
Security may be paid after deducting from the Redemption Price an amount equal
to the face amount of all such missing coupons, or the surrender of such missing
coupon or coupons may be waived by the Company and the Trustee if there be
furnished to them such security or indemnity as they may require to save each of
them and any Paying Agent harmless. If thereafter the Holder of such Security
shall surrender to the Trustee or any Paying Agent any such missing coupon in
respect of which a deduction shall have been made from the Redemption Price,
such Holder shall be entitled to receive the amount so deducted; provided,
however, that interest represented by coupons shall be payable only at an office
or agency located outside the United States (except as otherwise provided in
Section 1002) and, unless otherwise specified as contemplated by Section 301,
only upon presentation and surrender of those coupons.

         If any Security called for redemption shall not be so paid upon
surrender thereof for redemption, the principal (and premium or Make-Whole
Amount, if any) shall, until paid, bear interest from the Redemption Date at the
rate borne by the Security.

         SECTION 1107. Securities Redeemed in Part. Any Registered Security
which is to be redeemed only in part (pursuant to the provisions of this Article
or of Article Twelve) shall be surrendered at a Place of Payment therefor (with,
if the Company or the Trustee so requires,


                                       70
<PAGE>   78
due endorsement by, or a written instrument of transfer in form satisfactory to
the Company and the Trustee duly executed by, the Holder thereof or his attorney
duly authorized in writing) and the Company shall execute and the Trustee shall
authenticate and deliver to the Holder of such Security without service charge a
new Security or Securities of the same series, of any authorized denomination as
requested by such Holder in aggregate principal amount equal to and in exchange
for the unredeemed portion of the principal of the Security so surrendered. If a
Global Security is so surrendered, the Company shall execute and the Trustee
shall authenticate and deliver to the depository, without service charge, a new
Global Security in a denomination equal to and in exchange for the unredeemed
portion of the principal of the Global Security so surrendered.


                         ARTICLE TWELVE - SINKING FUNDS

         SECTION 1201. Applicability of Article. The provisions of this Article
shall be applicable to any sinking fund for the retirement of Securities of a
series except as otherwise specified as contemplated by Section 301 for
Securities of such series.

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

         SECTION 1202. Satisfaction of Sinking Fund Payments with Securities.
The Company may, in satisfaction of all or any part of any mandatory sinking
fund payment with respect to the Securities of a series, (1) deliver Outstanding
Securities of such series (other than any previously called for redemption)
together in the case of any Bearer Securities of such series with all unmatured
coupons appertaining thereto and (2) apply as a credit Securities of such series
which have been redeemed either at the election of the Company pursuant to the
terms of such Securities or through the application of permitted optional
sinking fund payments pursuant to the terms of such Securities, as provided for
by the terms of such Securities, or which have otherwise been acquired by the
Company; provided that such Securities so delivered or applied as a credit have
not been previously so credited. Such Securities shall be received and credited
for such purpose by the Trustee at the applicable Redemption Price specified in
such Securities for redemption through operation of the sinking fund and the
amount of such mandatory sinking fund payment shall be reduced accordingly.

         SECTION 1203. Redemption of Securities for Sinking Fund. Not less than
60 days prior to each sinking fund payment date for Securities of any series,
the Company will deliver to the Trustee an Officers' Certificate specifying the
amount of the next ensuing mandatory


                                       71
<PAGE>   79
sinking fund payment for that series pursuant to the terms of that series, the
portion thereof, if any, which is to be satisfied by payment of cash in the
currency or currencies, currency unit or units or composite currency or
currencies in which the Securities of such series are payable (except as
otherwise specified pursuant to Section 301 for the Securities of such series)
and the portion thereof, if any, which is to be satisfied by delivering and
crediting Securities of that series pursuant to Section 1202, and the optional
amount, if any, to be added in cash to the next ensuing mandatory sinking fund
payment, and will also deliver to the Trustee any Securities to be so delivered
and credited. If such Officers' Certificate shall specify an optional amount to
be added in cash to the next ensuing mandatory sinking fund payment, the Company
shall thereupon be obligated to pay the amount therein specified. Not less than
30 days before each such sinking fund payment date the Trustee shall select the
Securities to be redeemed upon such sinking fund payment date in the manner
specified in Section 1103 and cause notice of the redemption thereof to be given
in the name of and at the expense of the Company in the manner provided in
Section 1104. Such notice having been duly given, the redemption of such
Securities shall be made upon the terms and in the manner stated in Sections
1106 and 1107.


              ARTICLE THIRTEEN - REPAYMENT AT THE OPTION OF HOLDERS

         SECTION 1301. Applicability of Article. Repayment of Securities of any
series before their Stated Maturity at the option of Holders thereof shall be
made in accordance with the terms of such Securities, if any, and (except as
otherwise specified by the terms of such series established pursuant to Section
301) in accordance with this Article.

         SECTION 1302. Repayment of Securities. Securities of any series subject
to repayment in whole or in part at the option of the Holders thereof will,
unless otherwise provided in the terms of such Securities, be repaid at a price
equal to the principal amount thereof, together with interest, if any, thereon
accrued to the Repayment Date specified in or pursuant to the terms of such
Securities. The Company covenants that on or prior to the Repayment Date it will
deposit with the Trustee or with a Paying Agent (or, if the Company is acting as
its own Paying Agent, segregate and hold in trust as provided in Section 1003)
an amount of money in the currency or currencies, currency unit or units or
composite currency or currencies in which the Securities of such series are
payable (except as otherwise specified pursuant to Section 301 for the
Securities of such series) sufficient to pay the principal (or, if so provided
by the terms of the Securities of any series, a percentage of the principal) of,
and (except if the Repayment Date shall be an Interest Payment Date) accrued
interest on, all the Securities or portions thereof, as the case may be, to be
repaid on such date.

         SECTION 1303. Exercise of Option. Securities of any series subject to
repayment at the option of the Holders thereof will contain an "Option to Elect
Repayment" form on the reverse of such Securities. In order for any Security to
be repaid at the option of the Holder, the Trustee must receive at the Place of
Payment therefor specified in the terms of such Security (or at such other place
or places of which the Company shall from time to time notify


                                       72
<PAGE>   80
the Holders of such Securities) not earlier than 60 days nor later than 30 days
prior to the Repayment Date (1) the Security so providing for such repayment
together with the "Option to Elect Repayment" form on the reverse thereof duly
completed by the Holder (or by the Holder's attorney duly authorized in writing)
or (2) a telegram, telex, facsimile transmission or a letter from a member of a
national securities exchange, or the National Association of Securities Dealers,
Inc. ("NASD"), or a commercial bank or trust company in the United States
setting forth the name of the Holder of the Security, the principal amount of
the Security, the principal amount of the Security to be repaid, the CUSIP
number, if any, or a description of the tenor and terms of the Security, a
statement that the option to elect repayment is being exercised thereby and a
guarantee that the Security to be repaid, together with the duly completed form
entitled "Option to Elect Repayment" on the reverse of the Security, will be
received by the Trustee not later than the fifth Business Day after the date of
such telegram, telex, facsimile transmission or letter; provided, however, that
such telegram, telex, facsimile transmission or letter shall only be effective
if such Security and form duly completed are received by the Trustee by such
fifth Business Day. If less than the entire principal amount of such Security is
to be repaid in accordance with the terms of such Security, the principal amount
of such Security to be repaid, in increments of the minimum denomination for
Securities of such series, and the denomination or denominations of the Security
or Securities to be issued to the Holder for the portion of the principal amount
of such Security surrendered that is not to be repaid, must be specified. The
principal amount of any Security providing for repayment at the option of the
Holder thereof may not be repaid in part if, following such repayment, the
unpaid principal amount of such Security would be less than the minimum
authorized denomination of Securities of the series of which such Security to be
repaid is a part. Except as otherwise may be provided by the terms of any
Security providing for repayment at the option of the Holder thereof, exercise
of the repayment option by the Holder shall be irrevocable unless waived by the
Company.

         SECTION 1304. When Securities Presented for Repayment Become Due and
Payable. If Securities of any series providing for repayment at the option of
the Holders thereof shall have been surrendered as provided in this Article and
as provided by or pursuant to the terms of such Securities, such Securities or
the portions thereof, as the case may be, to be repaid shall become due and
payable and shall be paid by the Company on the Repayment Date therein
specified, and on and after such Repayment Date (unless the Company shall
default in the payment of such Securities on such Repayment Date) such
Securities shall, if the same were interest-bearing, cease to bear interest and
the coupons for such interest appertaining to any Bearer Securities so to be
repaid, except to the extent provided below, shall be void. Upon surrender of
any such Security for repayment in accordance with such provisions, together
with all coupons, if any, appertaining thereto maturing after the Repayment
Date, the principal amount of such Security so to be repaid shall be paid by the
Company, together with accrued interest, if any, to the Repayment Date;
provided, however, that coupons whose Stated Maturity is on or prior to the
Repayment Date shall be payable only at an office or agency located outside the
United States (except as otherwise provided in Section 1002) and, unless
otherwise specified pursuant to Section 301, only upon presentation and
surrender of such coupons; and provided further that, in the case of Registered
Securities, installments of


                                       73
<PAGE>   81
interest, if any, whose Stated Maturity is on or prior to the Repayment Date
shall be payable (but without interest thereon, unless the Company shall default
in the payment thereof) to the Holders of such Securities, or one or more
Predecessor Securities, registered as such at the close of business on the
relevant Record Dates according to their terms and the provisions of Section
307.

         If any Bearer Security surrendered for repayment shall not be
accompanied by all appurtenant coupons maturing after the Repayment Date, such
Security may be paid after deducting from the amount payable therefor as
provided in Section 1302 an amount equal to the face amount of all such missing
coupons, or the surrender of such missing coupon or coupons may be waived by the
Company and the Trustee if there be furnished to them such security or indemnity
as they may require to save each of them and any Paying Agent harmless. If
thereafter the Holder of such Security shall surrender to the Trustee or any
Paying Agent any such missing coupon in respect of which a deduction shall have
been made as provided in the preceding sentence, such Holder shall be entitled
to receive the amount so deducted; provided, however, that interest represented
by coupons shall be payable only at an office or agency located outside the
United States (except as otherwise provided in Section 1002) and, unless
otherwise specified as contemplated by Section 301, only upon presentation and
surrender of those coupons.

         If the principal amount of any Security surrendered for repayment shall
not be so repaid upon surrender thereof, such principal amount (together with
interest, if any, thereon accrued to such Repayment Date) shall, until paid,
bear interest from the Repayment Date at the rate of interest or Yield to
Maturity (in the case of Original Issue Discount Securities) set forth in such
Security.

         SECTION 1305. Securities Repaid in Part. Upon surrender of any
Registered Security which is to be repaid in part only, the Company shall
execute and the Trustee shall authenticate and deliver to the Holder of such
Security, without service charge and at the expense of the Company, a new
Registered Security or Securities of the same series, of any authorized
denomination specified by the Holder, in an aggregate principal amount equal to
and in exchange for the portion of the principal of such Security so surrendered
which is not to be repaid.


              ARTICLE FOURTEEN - DEFEASANCE AND COVENANT DEFEASANCE

         SECTION 1401. Applicability of Article: Company's Option to Effect
Defeasance or Covenant Defeasance. If, pursuant to Section 301, provision is
made for either or both of (a) defeasance of the Securities of or within a
series under Section 1402 or (b) covenant defeasance of the Securities of or
within a series under Section 1403, then the provisions of such Section or
Sections, as the case may be, together with the other provisions of this Article
(with such modifications thereto as may be specified pursuant to Section 301
with respect to any Securities), shall be applicable to such Securities and any
coupons appertaining thereto, and the


                                       74
<PAGE>   82
Company may at its option by Board Resolution, at any time, with respect to such
Securities and any coupons appertaining thereto, elect to have Section 1402 (if
applicable) or Section 1403 (if applicable) be applied to such Outstanding
Securities and any coupons appertaining thereto upon compliance with the
conditions set forth below in this Article.

         SECTION 1402. Defeasance and Discharge. Upon the Company's exercise of
the above option applicable to this Section with respect to any Securities of or
within a series, the Company shall be deemed to have been discharged from its
obligations with respect to such Outstanding Securities and any coupons
appertaining thereto on the date the conditions set forth in Section 1404 are
satisfied (hereinafter, "defeasance"). For this purpose, such defeasance means
that the Company shall be deemed to have paid and discharged the entire
indebtedness represented by such Outstanding Securities and any coupons
appertaining thereto, which shall thereafter be deemed to be "Outstanding" only
for the purposes of Section 1405 and the other Sections of this Indenture
referred to in clauses (A) and (B) below, and to have satisfied all of its other
obligations under such Securities and any coupons appertaining thereto and this
Indenture insofar as such Securities and any coupons appertaining thereto are
concerned (and the Trustee, at the expense of the Company, shall execute proper
instruments acknowledging the same), except for the following which shall
survive until otherwise terminated or discharged hereunder: (A) the rights of
Holders of such Outstanding Securities and any coupons appertaining thereto to
receive, solely from the trust fund described in Section 1404 and as more fully
set forth in such Section, payments in respect of the principal of (and premium
or Make-Whole Amount, if any) and interest, if any, on such Securities and any
coupons appertaining thereto when such payments are due, (B) the Company's
obligations with respect to such Securities under Sections 305, 306, 1002 and
1003, (C) the rights, powers, trusts, duties and immunities of the Trustee
hereunder and (D) this Article. Subject to compliance with this Article
Fourteen, the Company may exercise its option under this Section notwithstanding
the prior exercise of its option under Section 1403 with respect to such
Securities and any coupons appertaining thereto.

         SECTION 1403. Covenant Defeasance. Upon the Company's exercise of the
above option applicable to this Section with respect to any Securities of or
within a series, the Company shall be released from its obligations under
Sections 1004 to 1009, inclusive, and, if specified pursuant to Section 301, its
obligations under any other covenant contained herein or in any indenture
supplemental hereto, with respect to such Outstanding Securities and any coupons
appertaining thereto on and after the date the conditions set forth in Section
1404 are satisfied (hereinafter, "covenant defeasance"), and such Securities and
any coupons appertaining thereto shall thereafter be deemed to be not
"Outstanding" for the purposes of any direction, waiver, consent or declaration
or Act of Holders (and the consequences of any thereof) in connection with
Sections 1004 to 1009, inclusive, or such other covenant, but shall continue to
be deemed "Outstanding" for all other purposes hereunder. For this purpose, such
covenant defeasance means that, with respect to such Outstanding Securities and
any coupons appertaining thereto, the Company may omit to comply with and shall
have no liability in respect of any term, condition or limitation set forth in
any such Section or such other covenant, whether directly or indirectly, by
reason of any reference elsewhere herein to any


                                       75
<PAGE>   83
such Section or such other covenant or by reason of reference in any such
Section or such other covenant to any other provision herein or in any other
document and such omission to comply shall not constitute a default or an Event
of Default under Section 501(4) or 501(8) or otherwise, as the case may be, but,
except as specified above, the remainder of this Indenture and such Securities
and any coupons appertaining thereto shall be unaffected thereby.

accordance with their terms will provide, not later than the due date of any
payment of principal of (and premium or Make-Whole Amount, if any) and interest,
if any, on such Securities and any coupons appertaining thereto, money in an

without consideration of any reinvestment of such principal and interest, in the
opinion of a nationally recognized firm of independent public accountants
expressed in a written certification thereof delivered to the Trustee, to pay
and discharge, and which shall be applied by the Trustee (or other qualifying
trustee) to pay and discharge, (i) the principal of (and premium or Make-Whole
Amount, if any) and interest, if any, on such Outstanding Securities and any
coupons appertaining thereto on the Stated Maturity of such principal or

Company has received from, or there has been published by, the Internal Revenue
Service a ruling, or (ii) since the date of execution of this Indenture, there
has been a change in the applicable Federal income tax law, in either case to
the effect that, and based thereon such opinion shall confirm that, the Holders
of such Outstanding Securities and any coupons appertaining thereto will not
recognize income, gain or loss for Federal income tax purposes as a result of
such defeasance and will be subject to Federal income tax on the same amounts,
in the same manner and at the same times as would have been the case if such
defeasance had not occurred.

             (e) In the case of an election under Section 1403, the Company

Holders of such Outstanding Securities and any coupons appertaining thereto will
not recognize income, gain or loss for Federal income tax purposes as a result

Certificate and an Opinion of Counsel, each stating that all conditions
precedent to the defeasance under Section 1402 or the covenant defeasance under

Counsel to the effect that either (i) as a result of a deposit pursuant to
subsection (a) above and the related exercise of the Company's option under
Section 1402 or Section 1403 (as the case may be), registration is not required
under the Investment Company Act of 1940, as amended, by the Company, with
respect to the trust funds representing such deposit or by the Trustee for such
trust funds or (ii) all necessary registrations under said Act have been
effected.

             (g) Notwithstanding any other provisions of this Section, such
defeasance or covenant defeasance shall be effected in compliance with any
additional or substitute terms, conditions or limitations which may be imposed
on the Company in connection therewith pursuant to Section 301.

         SECTION 1405. Deposited Money and Government Obligations to Be Held in
Trust; Other Miscellaneous Provisions. Subject to the provisions of the last
paragraph of Section 1003, all money and Government Obligations (or other
property as may be provided pursuant to Section 301) (including the proceeds
thereof) deposited with the Trustee (or other qualifying trustee, collectively
for purposes of this Section 1405, the "Trustee") pursuant to Section 1404 in
respect of any Outstanding Securities of any series and any coupons appertaining
thereto shall be held in trust and applied by the Trustee, in accordance with
the provisions of such Securities and any coupons appertaining thereto and this
Indenture, to the payment, either directly or through any Paying Agent
(including the Company acting as its own Paying Agent)


                                       77
<PAGE>   85
as the Trustee may determine, to the Holders of such Securities and any coupons
appertaining thereto of all sums due and to become due thereon in respect of
principal (and premium or Make-Whole Amount, if any) and interest, but such
money need not be segregated from other funds except to the extent required by
law.

         Unless otherwise specified with respect to any Security pursuant to
Section 301, if, after a deposit referred to in Section 1404(a) has been made,
(a) the Holder of a Security in respect of which such deposit was made is
entitled to, and does, elect pursuant to Section 301 or the terms of such
Security to receive payment in a currency or currency unit other than that in
which the deposit pursuant to Section 1404(a) has been made in respect of such
Security, or (b) a Conversion Event occurs in respect of the currency or
currency unit in which the deposit pursuant to Section 1404(a) has been made,
the indebtedness represented by such Security and any coupons appertaining
thereto shall be deemed to have been, and will be, fully discharged and
satisfied through the payment of the principal of (and premium or Make-Whole
Amount, if any), and interest, if any, on such Security as the same becomes due
out of the proceeds yielded by converting (from time to time as specified below
in the case of any such election) the amount or other property deposited in
respect of such Security into the currency or currency unit in which such
Security becomes payable as a result of such election or Conversion Event based
on the applicable market exchange rate for such currency or currency unit in
effect on the second Business Day prior to each payment date, except, with
respect to a Conversion Event, for such currency or currency unit in effect (as
nearly as feasible) at the time of the Conversion Event.

         The Company shall pay and indemnify the Trustee against any tax, fee or
other charge imposed on or assessed against the Government Obligations deposited
pursuant to Section 1404 or the principal and interest received in respect
thereof other than any such tax, fee or other charge which by law is for the
account of the Holders of such Outstanding Securities and any coupons
appertaining thereto.

         Anything in this Article to the contrary notwithstanding, subject to
Section 606, the Trustee shall deliver or pay to the Company from time to time
upon Company Request any money or Government Obligations (or other property and
any proceeds therefrom) held by it as provided in Section 1404 which, in the
opinion of a nationally recognized firm of independent public accountants
expressed in a written certification thereof delivered to the Trustee, are in
excess of the amount thereof which would then be required to be deposited to
effect a defeasance or covenant defeasance, as applicable, in accordance with
this Article.

meeting or an adjourned meeting duly reconvened and at which a quorum is present
as aforesaid by the affirmative vote of the Holders of such specified percentage
in principal amount of the Outstanding Securities of that series.

respect to any request, demand, authorization, direction, notice, consent,
waiver or other action that this Indenture expressly provides may be made, given

Outstanding Securities affected thereby, or of the Holders of such series and
one or more additional series:

         direction, notice, consent, waiver or other action has been made, given
         or taken under this Indenture.

         SECTION 1505. Determination of Voting Rights; Conduct and Adjournment
of Meetings. (a) Notwithstanding any provisions of this Indenture, the Trustee
may make such reasonable regulations as it may deem advisable for any meeting of
Holders of Securities of a series in regard to proof of the holding of
Securities of such series and of the appointment of


                                       80
<PAGE>   88
proxies and in regard to the appointment and duties of inspectors of votes, the
submission and examination of proxies, certificates and other evidence of the
right to vote, and such other matters concerning the conduct of the meeting as
it shall deem appropriate. Except as otherwise permitted or required by any such
regulations, the holding of Securities shall be proved in the manner specified
in Section 104 and the appointment of any proxy shall be proved in the manner
specified in Section 104 or by having the signature of the Person executing the
proxy witnessed or guaranteed by any trust company, bank or banker authorized by
Section 104 to certify to the holding of Bearer Securities. Such regulations may
provide that written instruments appointing proxies, regular on their face, may
be presumed valid and genuine without the proof specified in Section 104 or
other proof.

             (b) The Trustee shall, by an instrument in writing appoint a
temporary chairman of the meeting, unless the meeting shall have been called by
the Company or by Holders of Securities as provided in Section 1502(b), in which
case the Company or the Holders of Securities of the series calling the meeting,
as the case may be, shall in like manner appoint a temporary chairman. A
permanent chairman and a permanent secretary of the meeting shall be elected by
vote of the Persons entitled to vote a majority in principal amount of the
Outstanding Securities of such series represented at the meeting.

             (c) At any meeting each Holder of a Security of such series or
proxy shall be entitled to one vote for each $1,000 principal amount of the
Outstanding Securities of such series held or represented by him; provided,
however, that no vote shall be cast or counted at any meeting in respect of any
Security challenged as not Outstanding and ruled by the chairman of the meeting
to be not Outstanding. The chairman of the meeting shall have no right to vote,
except as a Holder of a Security of such series or proxy.

             (d) Any meeting of Holders of Securities of any series duly called
pursuant to Section 1502 at which a quorum is present may be adjourned from time
to time by Persons entitled to vote a majority in principal amount of the
Outstanding Securities of such series represented at the meeting, and the
meeting may be held as so adjourned without further notice.

         SECTION 1506. Counting Votes and Recording Action of Meetings. The vote
upon any resolution submitted to any meeting of Holders of Securities of any
series shall be by written ballots on which shall be subscribed the signatures
of the Holders of Securities of such series or of their representatives by proxy
and the principal amounts and serial numbers of the Outstanding Securities of
such series held or represented by them. The permanent chairman of the meeting
shall appoint two inspectors of votes who shall count all votes cast at the
meeting for or against any resolution and who shall make and file with the
secretary of the meeting their verified written reports in duplicate of all
votes cast at the meeting. A record, at least in duplicate, of the proceedings
of each meeting of Holders of Securities of any Series shall be prepared by the
secretary of the meeting and there shall be attached to said record the original
reports of the inspectors of votes on any vote by ballot taken thereat and
affidavits by one or more persons having knowledge of the fact, setting forth a
copy of the notice of the meeting


                                       81
<PAGE>   89
and showing that said notice was given as provided in Section 1502 and, if
applicable, Section 1504. Each copy shall be signed and verified by the
affidavits of the permanent chairman and secretary of the meeting and one such
copy shall be delivered to the Company and another to the Trustee to be
preserved by the Trustee, the latter to have attached thereto the ballots voted
at the meeting. Any record so signed and verified shall be conclusive evidence
of the matters therein stated.


                  ARTICLE SIXTEEN - SUBORDINATION OF SECURITIES

         SECTION 1601. Agreement to Subordinate. Notwithstanding anything in
this Indenture to the contrary (other than Article Four of this Indenture), the
Company covenants and agrees, and each Holder of a Security, by his acceptance
thereof, likewise covenants and agrees, that, to the extent and in the manner
hereinafter set forth in this Article, the Indebtedness represented by the
Securities and the payment of any Obligations with respect to each and all of
the Securities are hereby expressly made subordinate and subject in right of
payment to the prior payment in full of all Senior Indebtedness.

         SECTION 1602. Payment Over of Proceeds upon Dissolution, Etc. In the
event of (a) any insolvency or bankruptcy case or Proceeding, or any
receivership, liquidation, reorganization or other similar case or Proceeding in
connection therewith, relative to the Company or to its creditors, as such, or
to its assets, or (b) any liquidation, dissolution or other winding up of the
Company, whether voluntary or involuntary and whether or not involving
insolvency or bankruptcy, or (c) any assignment for the benefit of creditors or
any other marshaling of assets and liabilities of the Company, then and in any
such event specified in (a), (b) or (c) above (each such event, if any, herein
sometimes referred to as a "Proceeding")

                  (1) the holders of Senior Indebtedness shall first be entitled
         to receive payment in full of all Obligations due or to become due on
         or in respect of all Senior Indebtedness, or provision shall be made
         for such payment in cash or cash equivalents or otherwise in a manner
         satisfactory to the holders of Senior Indebtedness, before the Holders
         of the Securities are entitled to receive any payment or distribution
         on account of principal of or premium, if any, or interest on or other
         Obligations in respect of the Securities or on account of any purchase,
         redemption or other acquisition of Securities by the Company or any
         Subsidiary (individually and collectively, a "Securities Payment"), and

                  (2) any payment or distribution of assets of the Company of
         any kind or character, whether in cash, property or securities (other
         than Capital Stock or securities of the Company as reorganized or
         readjusted, or securities of the Company or any other corporation
         provided for by a plan of reorganization or readjustment, the payment
         of which is subordinate, at least to the extent provided in this
         Article Sixteen with respect to the Securities, to the payment in full,
         without diminution or modification by such


                                       82
<PAGE>   90
         plan, of all Senior Indebtedness), to which the Holders would be
         entitled except for the provisions of this Article Sixteen, shall be
         paid by the liquidating trustee or agent or other person making such a
         payment or distribution, directly to the holders of Senior
         Indebtedness) (or their representative(s) or trustee(s) acting on their
         behalf), ratably according to the aggregate amounts remaining unpaid on
         account of the principal of or interest on and other amounts due on the
         Senior Indebtedness held or represented by each, to the extent
         necessary to make payment in full of all Senior Indebtedness remaining
         unpaid, after giving effect to any concurrent payment or distribution
         to the holders of such Senior Indebtedness.

         In the event that, notwithstanding the foregoing provisions of this
Section 1601, the Trustee or the Holder of any Security shall have received any
payment or distribution of assets of the Company of any kind or character,
whether in cash, property or securities (other than Capital Stock or securities
of the Company as reorganized or readjusted, or securities of the Company or any
other corporation provided for by a plan of reorganization or readjustment, the
payment of which is subordinate, at least to the extent provided in this Article
with respect to the Securities, to the payment in full, without diminution or
modification by such plan, of Senior Indebtedness), before all Senior
Indebtedness is paid in full or payment thereof provided for in cash or cash
equivalents or otherwise in a manner satisfactory to the holders of Senior
Indebtedness, such payment or distribution shall be held in trust for the
benefit of, and be paid over to, the holders of the Senior Indebtedness
remaining unpaid (or their representative(s) or trustee(s) acting on their
behalf), ratably as aforesaid, for application to the payment of such Senior
Indebtedness until such Senior Indebtedness shall have been paid in full, after
giving effect to any concurrent payment or distribution to the holders of such
Senior Indebtedness.

         The consolidation of the Company with, or the merger of the Company
into, another Person or the liquidation or dissolution of the Company following
the conveyance or transfer of all or substantially all of its properties and
assets as an entirety to another Person upon the terms and conditions set forth
in Article Eight shall not be deemed a Proceeding for the purposes of this
Section 1602 if the Person formed by such consolidation or into which the
Company is merged or the Person which acquires by conveyance or transfer such
properties and assets as an entirety, as the case may be, shall, as a part of
such consolidation, merger, conveyance or transfer, comply with the conditions
set forth in Article Eight.

         SECTION 1603. No Payment When Senior Indebtedness in Default. Anything
in this Indenture to the contrary notwithstanding, no payment on account of
principal of or redemption of, interest on or other amounts due on the
Securities, and no redemption, purchase, or other acquisition of the Securities,
shall be made by or on behalf of the Company (i) unless full payment of amounts
then due for principal and interest and of all other obligations then due on all
Senior Indebtedness has been made or duly provided for pursuant to the terms of
the instrument governing such Senior Indebtedness, (ii) if, at the time of such
payment, redemption, purchase or other acquisition, or immediately after giving
effect thereto, there shall exist under any Senior Indebtedness, or any
agreement pursuant to which any Senior Indebtedness is issued, any default,
which default shall not have been cured or waived


                                       83
<PAGE>   91
and which default shall have resulted in the full amount of such Senior
Indebtedness being declared due and payable or (iii) if, at the time of such
payment, redemption, purchase or other acquisition, the Trustee shall have
received written notice from the holder or holders of any Senior Indebtedness or
their representative or representatives (a "Payment Blockage Notice") that there
exists under such Senior Indebtedness, or any agreement pursuant to which such
Senior Indebtedness is issued, any default, which default shall not have been
cured or waived, permitting the holders thereof to declare the full amount of
such Senior Indebtedness due and payable, but only for the period (the "Payment
Blockage Period") commencing on the date of receipt of the Payment Blockage
Notice and ending (unless earlier terminated by notice given to the Trustee by
the Holders of such Senior Indebtedness) on the earlier of (A) the date on which
such event of default shall have been cured or waived or (B) 180 days from the
receipt of the Payment Blockage Notice. Upon termination of a Payment Blockage
Period, payments on account of principal of or interest on the Securities and
redemptions, purchases or other acquisitions may be made by or on behalf of the
Company. Notwithstanding anything herein to the contrary, (A) only one Payment
Blockage Notice may be given during any period of 360 consecutive days with
respect to the same event of default and any other events of default on the same
issue of Senior Indebtedness existing and known to the person giving such notice
at the time of such notice and (B) no new Payment Blockage Period may be
commenced by the holder or holders of the same issue of Senior Indebtedness or
their representative or representatives during any period of 360 consecutive
days unless all events of default which were the object of the immediately
preceding Payment Blockage Notice, and any other event of default on the same
issue of Senior Indebtedness existing and known to the person giving such notice
at the time of such notice, have been cured or waived.

         In the event that, notwithstanding the provisions of this Section 1603,
payments are made by or on behalf of the Company in contravention of the
provisions of this Section 1603, such payments shall be held by the Trustee, any
Paying Agent or the Holders, as applicable, in trust for the benefit of, and
shall be paid over to and delivered to, the holders of Senior Indebtedness or
their representative or the trustee under the indenture or other agreement (if
any), pursuant to which any instruments evidencing any Senior Indebtedness may
have been issued, as their respective interests may appear, for application to
the payment of all Senior Indebtedness remaining unpaid to the extent necessary
to pay all Senior Indebtedness in full in accordance with the terms of such
Senior Indebtedness, after giving effect to any concurrent payment or
distribution to or for the holders of Senior Indebtedness.

         The provisions of this Section shall not apply to any payment with
respect to which Section 1602 would be applicable.

         SECTION 1604. Reliance by Senior Indebtedness on Subordination
Provisions. Each Holder of any Security by his acceptance thereof acknowledges
and agrees that the foregoing subordination provisions are, and are intended to
be, an inducement and a consideration for each holder of any Senior
Indebtedness, whether such Senior Indebtedness was created or acquired before or
after the issuance of the Securities, to acquire and continue to hold, or to
continue to hold, such Senior Indebtedness, and such holder of Senior
Indebtedness shall be


                                       84
<PAGE>   92
deemed conclusively to have relied on such subordination provisions in acquiring
and continuing to hold or in continuing to hold such Senior Indebtedness.

         SECTION 1605. Subrogation to Rights of Holders of Senior Indebtedness.
Subject to the payment in full of all Obligations due or to become due on or in
respect of Senior Indebtedness, or the provision for such payment in cash or
cash equivalents or otherwise in a manner satisfactory to the holders of Senior
Indebtedness, the Holders of the Securities shall be subrogated to the extent of
the payments or distributions made to the holders of such Senior Indebtedness
pursuant to the provisions of this Article Sixteen to the rights of the holders
of such Senior Indebtedness to receive payments and distributions of cash,
property and securities applicable to the Senior Indebtedness until the
principal of and premium, if any, and interest on the Securities shall be paid
in full. For purposes of such subrogation, no payments or distributions to the
holders of the Senior Indebtedness of any cash, property or securities to which
the Holders of the Securities or the Trustee would be entitled except for the
provisions of this Article Sixteen, and no payments over pursuant to the
provisions of this Article Sixteen to the holders of Senior Indebtedness by
Holders of the Securities or the Trustee, shall, as among the Company, its
creditors other than holders of Senior Indebtedness and the Holders of the
Securities, be deemed to be a payment or distribution by the Company to or on
account of the Senior Indebtedness.

         SECTION 1606. Provisions Solely to Define Relative Rights. The
provisions of this Article Sixteen are and are intended solely for the purpose
of defining the relative rights of the Holders of the Securities on the one hand
and the holders of Senior Indebtedness on the other hand. Nothing contained in
this Article or elsewhere in this Indenture or in the Securities is intended to
or shall (a) impair, as among the Company, its creditors other than holders of
Senior Indebtedness and the Holders of the Securities, the obligation of the
Company, which is absolute and unconditional (and which, subject to the rights
under this Article Sixteen of the holders of Senior Indebtedness, is intended to
rank equally with all other general obligations of the Company), to pay to the
Holders of the Securities the principal of and premium, if any, and interest on
the Securities as and when the same shall become due and payable in accordance
with their terms; or (b) affect the relative rights against the Company of the
Holders of the Securities and creditors of the Company other than the holders of
Senior Indebtedness; or (c) prevent the Trustee or the Holder of any Security
from exercising all remedies otherwise permitted by applicable law upon default
under this Indenture, subject to the rights, if any, under this Article of the
holders of Senior Indebtedness to receive cash, property and securities
otherwise payable or deliverable to the Trustee or such Holder.

         SECTION 1607. Trustee to Effectuate Subordination. Each Holder of a
Security by his acceptance thereof authorizes and directs the Trustee on his
behalf to take such action as may be necessary or appropriate to effectuate, as
between the Holders of the Securities and the holders of Senior Indebtedness,
the subordination provided in this Article Sixteen and appoints the Trustee his
attorney-in-fact for any and all such purposes, including, in the event of any
dissolution, winding up or liquidation or reorganization under any applicable
bankruptcy law of the Company (whether in bankruptcy, insolvency or receivership
Proceedings or otherwise),


                                       85
<PAGE>   93
the timely filing of a claim for the unpaid balance of such Holder's Securities
in the form required in such Proceedings and the causing of such claim to be
approved. If the Trustee does not file a claim or proof of debt in the form
required in such Proceedings prior to 30 days before the expiration of the time
to file such claims or proofs, then the holders of Senior Indebtedness, jointly,
or their representatives shall have the right to file an appropriate claim for
and on behalf of the Holders and to demand, sue for, collect, receive and
receipt for the payments and distributions in respect of the Securities which
are required to be paid or delivered to the holders of Senior Indebtedness as
provided in this Article Sixteen and to take all such other action in the name
of the Holders or otherwise, as such holder of Senior Indebtedness or
representative thereof may determine to be necessary or appropriate for the
enforcement of the provisions of this Article Sixteen.

         SECTION 1608. No Waiver of Subordination Provisions. No right of any
present or future holder of any Senior Indebtedness to enforce subordination as
herein provided shall at any time in any way be prejudiced or impaired by any
act or failure to act on the part of the Company or by any act or failure to
act, in good faith, by any such holder or any representative or trustee
therefor, or by any non-compliance by the Company with the terms, provisions and
covenants of this Indenture, regardless of any knowledge thereof any such holder
may have or be otherwise charged with.

         Without in any way limiting the generality of the foregoing paragraph,
the holders of Senior Indebtedness may, at any time from time to time, without
the consent of or notice to the Trustee or the Holders of the Securities,
without incurring responsibility to the Holders of the Securities and without
impairing or releasing the subordination provided in this Article Sixteen or the
obligations hereunder of the Holders of the Securities to the holders of Senior
Indebtedness, do any one or more of the following: (i) change the manner, place
or terms of payment or extend the time of payment of, or renew or alter, Senior
Indebtedness, or otherwise amend or supplement in any manner Senior Indebtedness
or any instrument evidencing the same or any agreement under which Senior
Indebtedness is outstanding; (ii) sell, exchange, release or otherwise deal with
any property pledged, mortgaged or otherwise securing Senior Indebtedness; (iii)
release any Person liable in any manner for the collection of Senior
Indebtedness and settle or compromise Senior Indebtedness (which, to the extent
so settled and compromised, shall be deemed to have been paid in full for all
purposes hereof); (iv) apply any amounts received to any liability of the
Company owing to holders of Senior Indebtedness; and (v) exercise or refrain
from exercising any rights against the Company and any other Person.

         SECTION 1609. Notice to Trustee. The Company shall give prompt written
notice to the Trustee of any default or event of default with respect to any
Senior Indebtedness or of any fact known to the Company which would prohibit the
making of any payment to or by the Trustee in respect of the Securities pursuant
to the provisions of this Article Sixteen. Notwithstanding the provisions of
this Article Sixteen or any other provision of this Indenture, the Trustee shall
not be charged with knowledge of the existence of any facts which would prohibit
the making of any payment to or by the Trustee in respect of the Securities,
unless and


                                       86
<PAGE>   94
until the Trustee shall have received written notice thereof from the Company or
a holder of Senior Indebtedness or from any representative or trustee acting on
their behalf; and, prior to the receipt of any such written notice, the Trustee,
subject to the provisions of Section 612, shall be entitled in all respects to
assume that no such facts exist; provided, however, that if the Trustee shall
not have received the notice provided for in this Section at least three
Business Days prior to the date upon which by the terms hereof any money may
become payable for any purpose (including, without limitation, the payment of
the principal of and premium, if any, or interest on any Security), then,
anything herein contained to the contrary notwithstanding, the Trustee shall
have full power and authority to receive such money and to apply the same to the
purpose for which such money was received and shall not be affected by any
notice to the contrary which may be received by it within three Business Days
prior to such date. Nothing contained in this Article Sixteen or any other
Article of this Indenture or in any of the Securities shall prevent (a) the
Company, at any time except during the pendency of any Proceeding, or under the
conditions described in Section 1603, from making payments at any time in
respect of the Securities, or (b) the application by the Trustee of any money
deposited with it hereunder to the payment of or on account of the Securities,
or the retention thereof by any Holder, if the Trustee did not have notice, as
provided in this Section 1609, that such payment would have been prohibited by
the provisions of this Article Sixteen.

         Subject to the provisions of Section 612, the Trustee shall be entitled
to rely on the delivery to it of a written notice by a Person representing
himself to be a holder of Senior Indebtedness (or a representative or trustee
therefor) to establish that such notice has been given by a holder of Senior
Indebtedness (or a trustee therefor). In the event that the Trustee determines
in good faith that further evidence is required with respect to the right of any
Person as a holder of Senior Indebtedness to participate in any payment or
distribution pursuant to this Article Sixteen, the Trustee may request such
Person to furnish evidence to the reasonable satisfaction of the Trustee as to
the amount of Senior Indebtedness held by such Person, the extent to which such
Person is entitled to participate in such payment or distribution and any other
facts pertinent to the rights of such Person under this Article Sixteen, and if
such evidence is not furnished, the Trustee may defer any payment to such Person
pending judicial determination as to the right of such Person to receive such
payment.

         SECTION 1610. Reliance on Judicial Order or Certificate of Liquidating
Agent. Upon any payment or distribution of assets of the Company referred to in
this Article Sixteen, the Trustee, subject to the provisions of Section 612, and
the Holders of the Securities shall be entitled to rely upon any order or decree
entered by any court of competent jurisdiction in which any Proceeding is
pending, or a certificate of the trustee in bankruptcy, receiver, liquidating
trustee, custodian, assignee for the benefit of creditors, agent or other Person
making such payment or distribution, delivered to the Trustee or to the Holders
of Securities, for the purpose of ascertaining the Persons entitled to
participate in such payment or distribution, the holders of the Senior
Indebtedness and other indebtedness of the Company, the amount thereof or
payable thereon, the amount or amounts paid or distributed thereon and all other
facts pertinent thereto or to this Article.


                                       87
<PAGE>   95
         SECTION 1611. Trustee Not Fiduciary for Holders of Senior Indebtedness.
The Trustee shall not be deemed to owe any fiduciary duty to the holders of
Senior Indebtedness. Nothing contained in this Article Sixteen or elsewhere in
this Indenture, or in any of the Securities, shall prevent the application by
the Trustee of any moneys which were deposited with it hereunder, prior to its
receipt of written notice of facts which would prohibit such application, for
the purpose of the payment of or on account of the principal of or interest on,
the Securities unless, prior to the date on which such application is made by
the Trustee, the Trustee shall be charged with notice under Section 1609 hereof
of the facts which would prohibit the making of such application.

         SECTION 1612. Rights of Trustee as Holder of Senior Indebtedness;
Preservation of Trustee's Rights. The Trustee in its individual capacity shall
be entitled to all the rights set forth in this Article Sixteen with respect to
any Senior Indebtedness which may at any time be held by it, to the same extent
as any other holder of Senior Indebtedness, and nothing in this Indenture shall
deprive the Trustee of any of its rights as such holder. Nothing in this Article
shall apply to claims of, or payments to, the Trustee under or pursuant to
Section 606.

         SECTION 1613. Article Applicable to Paying Agents. In case at any time
any Paying Agent other than the Trustee shall have been appointed by the Company
and be then acting hereunder, the term "Trustee" as used in this Article Sixteen
shall in such case (unless the context otherwise requires) be construed as
extending to and including such Paying Agent within its meaning as fully for all
intents and purposes as if such Paying Agent were named in this Article in
addition to or in place of the Trustee; provided, however, that Section 1612
shall not apply to the Company or any Affiliate of the Company if it or such
Affiliate acts as Paying Agent.

                  ARTICLE SEVENTEEN - CONVERSION OF SECURITIES

         SECTION 1701. Applicability of Article; Conversion Privilege and
Conversion Price.

         Securities of any series which are convertible shall be convertible in
accordance with their terms and (except as otherwise specified as contemplated
by Section 301 for Securities of any series) in accordance with this Article
Seventeen. Subject to and upon compliance with the provisions of this Article
Seventeen, at any time during the period specified in the Securities, at the
option of the Holder thereof, any Security or any portion of the principal
amount thereof which is $1,000 or an integral multiple of $1,000 may be
converted at the principal amount thereof, or of such portion thereof, into
fully paid and nonassessable shares (calculated as to each conversion to the
nearest 1/100 of a share) of Common Stock of the Company, at the Conversion
Price, determined as hereinafter provided, in effect at the time of conversion.
In case a Security or portion thereof is called for redemption, such conversion
right in respect of the Security or portion so called shall expire at the close
of business on the Business Day immediately preceding the Redemption Date,
unless the Company defaults in making the payment due upon redemption, in which
case such conversion right shall terminate on the date such default is cured.


                                       88
<PAGE>   96
         The price at which shares of Common Stock shall be delivered upon
conversion (herein called the "Conversion Price") of Securities of any series
shall be specified in such Securities. The Conversion Price shall be adjusted in
certain instances as provided in Section 1704.

         In case the Company shall, by dividend or otherwise, declare or make a
distribution on its Common Stock referred to in paragraph (4) of Section 1704,
the Holder of each Security, upon the conversion thereof pursuant to this
Article Seventeen subsequent to the close of business on the date fixed for the
determination of stockholders entitled to receive such distribution and prior to
the effectiveness of the Conversion Price adjustment in respect of such
distribution pursuant to paragraph (4) of Section 1704, shall be entitled to
receive for each share of Common Stock into which such Security is converted,
the portion of the evidence of indebtedness, shares of Capital Stock or assets
so distributed applicable to one share of Common Stock; provided, however, that,
at the election of the Company (whose election shall be evidenced by a Board
Resolution filed with the Trustee) with respect to all Holders so converting,
the Company may, in lieu of distributing to such Holder any portion of such
distribution not consisting of cash or securities of the Company, pay such
Holder an amount in cash equal to the fair market value thereof (as determined
in good faith by the Board of Directors, whose determination shall be conclusive
and described in a Board Resolution filed with the Trustee). If any conversion
of a Security entitled to the benefits described in the immediately preceding
sentence occurs prior to the payment date for a distribution to holders of
Common Stock which the Holder of the Security so converted is entitled to
receive in accordance with the immediately preceding sentence, the Company may
elect (such election to be evidenced by a Board Resolution filed with the
Trustee) to distribute to such Holder a due bill for the evidences of
indebtedness, shares of Capital Stock or assets to which such Holder is so
entitled, provided that such due bill (i) meets any applicable requirements of
the principal national securities exchange or other market on which the Common
Stock is then traded, and (ii) requires payment or delivery of such evidences of
indebtedness or assets no later than the date of payment or delivery thereof to
holders of Common Stock receiving such distribution.

         SECTION 1702. Exercise of Conversion Privilege.

         In order to exercise the conversion privilege, the Holder of any
Security to be converted shall surrender such Security, duly endorsed or
assigned to the Company or in blank, at any office or agency maintained by the
Company pursuant to Section 1002, accompanied by written notice to the Company
at such office or agency that the Holder elects to convert such Security or, if
less than the entire principal amount thereof is to be converted, the portion
thereof to be converted and shall comply with any additional requirements set
forth in such Security. Securities surrendered for conversion during the period
from the close of business on any Regular Record Date next preceding any
Interest Payment Date to the opening of business on such Interest Payment Date
shall (except for Securities the Maturity of which is prior to such Interest
Payment Date) be accompanied by payment in New York Clearing House funds or
other funds acceptable to the Company of an amount equal to the interest payable
on such Interest Payment Date on the principal amount of Securities being
surrendered for conversion and such interest shall be paid on such Interest
Payment Date as provided in


                                       89
<PAGE>   97
Section 307. Except as provided in the preceding sentence, no payment or
adjustment shall be made upon any conversion on account of any interest accrued
on the Securities surrendered for conversion or on account of any dividends on
the Common Stock issued upon conversion.

         The Company's delivery to the Holder of the fixed number of shares of
the Common Stock of the Company (and any cash in lieu of any fractional share of
Common Stock) into which the Security is convertible shall be deemed to satisfy
the Company's obligation to pay the principal amount of the Security and all
accrued interest and original issue discount that has not previously been paid.
The shares of Common Stock of the Company so delivered shall be treated as
issued first in payment of accrued interest and original issue discount and then
in payment of principal. Thus, accrued interest and original issue discount
shall be treated as paid, rather than canceled, extinguished or forfeited.

         Securities shall be deemed to have been converted immediately prior to
the close of business on the day of surrender of such Securities for conversion
in accordance with the foregoing provisions, and at such time the rights of the
Holders of such Securities as Holders shall cease, and the Person or Persons
entitled to receive the Common Stock issuable upon conversion shall be treated
for all purposes as the record holder or holders of such Common Stock at such
time. As promptly as practicable on or after the conversion date, the Company
shall issue and shall deliver at such office or agency a certificate or
certificates for the number of full shares of Common Stock issuable upon
conversion, together with payment in lieu of any fraction of a share, as
provided in Section 1703.

         In the case of any Security which is converted in part only, as
promptly as practicable on or after the conversion date the Company shall
execute and the Trustee shall authenticate and make available for delivery to
the Holder thereof (or the Depositary in the case of a Global Security), at the
expense of the Company, a new Security or Securities, of authorized
denominations in aggregate principal amount equal to the unconverted portion of
the principal amount of such Security.

         SECTION 1703. Fractions of Shares.

         No fractional shares of Common Stock shall be issued upon conversion of
Securities. If more than one Security shall be surrendered for conversion at one
time by the same Holder, the number of full shares of Common Stock which shall
be issuable upon conversion thereof shall be computed on the basis of the
aggregate principal amount of the Securities (or specified portions thereof) so
surrendered. Instead of any fractional share of Common Stock which would
otherwise be issuable upon conversion of any Security or Securities (or
specified portions thereof), the Company shall pay a cash adjustment (rounded to
the nearest cent) in respect of such fraction in an amount equal to the same
fraction of the Closing Price per share of the Common Stock on the day of
conversion (or, if such day is not a Trading Day, on the Trading Day immediately
preceding such day).


                                       90
<PAGE>   98
         SECTION 1704. Adjustment of Conversion Price.

         The Conversion Price shall be subject to adjustment from time to time
as follows:

                  (1) If the Company pays or makes a dividend or other
         distribution (a) on its Common Stock exclusively in Common Stock or (b)
         on any other class of Capital Stock of the Company, which dividend or
         distribution includes Common Stock of the Company, the Conversion Price
         in effect at the opening of business on the day following the date
         fixed for the determination of stockholders entitled to receive such
         dividend or other distribution (the "Dividend Record Date") shall be
         reduced by multiplying such Conversion Price by a fraction of which the
         numerator shall be the number of shares of Common Stock of the Company
         outstanding at the close of business on the Dividend Record Date and
         the denominator shall be the sum of such number of shares and the total
         number of shares constituting such dividend or other distribution. Such
         reduction shall become effective immediately after the opening of
         business on the day following the date fixed for such determination.
         For the purposes of this paragraph (1), the number of shares of Common
         Stock of the Company at any time outstanding shall not include shares
         held in the treasury of the Company, but shall include shares issuable
         in respect of scrip certificates issued in lieu of fractions of shares
         of Common Stock. The Company shall not pay any dividend or make any
         distribution on shares of Common Stock held in the treasury of the
         Company.

                  (2) Subject to paragraph (6) of this Section, if the Company
         pays or makes a dividend or other distribution on its Common Stock
         consisting exclusively of Short Term Rights (as defined below), or
         otherwise issues Short Term Rights to all holders of its Common Stock,
         the Conversion Price in effect at the opening of business on the day
         following the record date for the determination of holders of Common
         Stock entitled to receive such Short Term Rights (the "Rights Record
         Date") shall be reduced by multiplying such Conversion Price by a
         fraction of which the numerator shall be the number of shares of Common
         Stock of the Company outstanding at the close of business on the Rights
         Record Date plus the number of shares of Common Stock of the Company
         which the aggregate of the offering price of the total number of shares
         of Common Stock so offered for subscription or purchase would purchase
         at such current market price and the denominator shall be the number of
         shares of Common Stock of the Company outstanding at the close of
         business on the Rights Record Date plus the number of shares of Common
         Stock so offered for subscription or purchase. Such reduction shall
         become effective immediately after the opening of business on the day
         following the Rights Record Date. For the purposes of this paragraph
         (2), the number of shares of Common Stock of the Company at any time
         outstanding shall not include shares held in the treasury of the
         Company, but shall include shares issuable in respect of scrip
         certificates issued in lieu of fractions of shares of Common Stock of
         the Company. The Company shall not issue any rights, options or
         warrants in respect of shares of its Common Stock held in the treasury
         of the Company. When used in this Section 1704, the term "Short Term
         Rights" shall mean rights, warrants or options


                                       91
<PAGE>   99
         entitling the holders thereof (for a period commencing no earlier than
         the Rights Record Date and expiring not more than 45 days after the
         Rights Record Date) to subscribe for or purchase shares of Common Stock
         of the Company at a price per share less than the current market price
         per share (determined as provided in paragraph (7) of this Section
         1704) of the Common Stock of the Company on the Rights Record Date.

                  (3) In case outstanding shares of Common Stock of the Company
         shall be subdivided into a greater number of shares of Common Stock,
         the Conversion Price in effect at the opening of business on the day
         following the day upon which such subdivision becomes effective shall
         be proportionately reduced, and, conversely, in case outstanding shares
         of Common Stock of the Company shall be combined into a smaller number
         of shares of Common Stock, the Conversion Price in effect at the
         opening of business on the day following the day upon which such
         combination becomes effective shall be proportionately increased, such
         reduction or increase, as the case may be, to become effective
         immediately after the opening of business on the day following the day
         upon which such subdivision or combination becomes effective.

                  (4) Subject to the last sentence of this paragraph (4) of this
         Section, if the Company, by dividend or otherwise, (a) distributes to
         all holders of its Common Stock evidences of its indebtedness, shares
         of any class of Capital Stock of the Company or other assets (other
         than cash dividends out of current or retained earnings), or (b)
         distributes to substantially all holders of Common Stock rights or
         warrants to subscribe for securities (other than Short Term Rights to
         which paragraph (2) of this Section 1704 applies), the Conversion Price
         shall be reduced by multiplying such Conversion Price by a fraction of
         which the numerator shall be the current market price per share
         (determined as provided in paragraph (7) of this Section 1704) of the
         Common Stock of the Company on the Reference Date (as defined below)
         less the fair market value (as determined in good faith by the Board of
         Directors, whose determination shall be conclusive and described in a
         Board Resolution filed with the Trustee), on the Reference Date, of the
         portion of the evidences of indebtedness and other assets so
         distributed or of such subscription rights or warrants applicable to
         one share of Common Stock (collectively, the "Market Value of the
         Distribution") and the denominator shall be such current market price
         per share of the Common Stock of the Company. Such reduction shall
         become effective immediately prior to the opening of business on the
         day (the "Reference Date") following the later of (a) the date fixed
         for the payment of such distribution and (b) the date 20 days after
         notice relating to such distribution is required to be given pursuant
         to Section 1706(a). If the Board of Directors determines the fair
         market value of any distribution for purposes of this paragraph (4) by
         reference to the actual or when issued trading market for any
         securities comprising such distribution, it must in doing so consider
         the prices in such market over the same period used in computing the
         current market price per share pursuant to paragraph (7) of this
         Section 1704. In the event that, with respect to any distribution to
         which this paragraph (4) of Section 1704 would otherwise apply, the
         Market Value of the Distribution is greater than the current market
         price per share of


                                       92
<PAGE>   100
         the Common Stock (such distribution being referred to herein as an
         "Unadjusted Distribution"), then the adjustment provided by this
         paragraph (4) shall not be made and in lieu thereof the provisions of
         Section 1711 shall apply with respect to such Unadjusted Distribution.

                  (5) The Company may, but shall not be required to, make such
         reductions in the Conversion Price, in addition to those required by
         paragraphs (1), (2), (3), and (4) of this Section 1704, as it considers
         to be advisable in order that any event treated for Federal income tax
         purposes as a dividend of stock or stock rights shall not be taxable to
         the recipients. In addition, the Company, from time to time, may
         decrease the Conversion Price by any amount and for any reason,
         temporarily or otherwise, including situations where the Board of
         Directors determines such decrease to be fair and appropriate with
         respect to transactions in which holders of Common Stock have the right
         to participate.

                  (6) Rights or warrants issued or distributed by the Company to
         all holders of its Common Stock entitling the holders thereof to
         subscribe for or purchase shares of Common Stock or Preferred Stock,
         which rights or warrants (i) are deemed to be transferred with such
         shares of Common Stock, (ii) are not exercisable and (iii) are also
         issued or distributed in respect of future issuances of Common Stock,
         in each case in clauses (i) through (iii) until the occurrence of a
         specified event or events ("Trigger Events"), shall for purposes of
         this Section 1704 not be deemed issued or distributed until the
         occurrence of the earliest Trigger Event. Each share of Common Stock
         issued upon conversion of Securities pursuant to this Article Seventeen
         shall be entitled to receive the appropriate number of Common Stock
         purchase rights (the "Rights"), if any, and the certificates
         representing the Common Stock issued upon conversion shall bear such
         legends, if any[, in each case as provided by and subject to the terms
         of the [Stockholders Rights Plan] adopted by the Board of Directors on
         ______________ (the "Rights Plan") as in effect at the time of such
         conversion]. Notwithstanding anything to the contrary in this Article
         Seventeen, there shall not be any adjustment to the Conversion Price as
         a result of (i) the distribution of separate certificates representing
         the Rights; (ii) the occurrence of certain events entitling holders of
         Rights to receive, upon exercise thereof, Common Stock or other
         securities of the Company or other securities of another corporation;
         or (iii) the exercise of such Rights, all in accordance with the Rights
         Plan. No adjustment in the Conversion Price need be made for rights to
         purchase or the sale of Common Stock pursuant to a Company plan
         providing for reinvestment of dividends or interest.

                  (7) For the purpose of any computation under paragraph (2),
         (4) or (5) of this Section 1704, the "current market price" per share
         of Common Stock of the Company on any date shall be deemed to be the
         average of the daily Closing Prices for the 15 consecutive Trading Days
         selected by the Company commencing not more than 30 Trading Days
         before, and ending not later than, the date in question.

<PAGE>   101
                  (8) No adjustment in the Conversion Price shall be required
         unless such adjustment would require an increase or decrease of at
         least 1% in the Conversion Price; provided, however, that any
         adjustments which by reason of this paragraph (8) are not required to
         be made shall be carried forward and taken into account in any
         subsequent adjustment. All calculations under this Article Seventeen
         shall be made to the nearest cent or to the nearest one-hundredth of a
         share of Common Stock, as the case may be.

                  (9) Anything herein to the contrary notwithstanding, in the
         event the Company shall declare any dividend or distribution requiring
         an adjustment in the Conversion Price hereunder and shall, thereafter
         and before the payment of such dividend or distribution to
         stockholders, legally abandon its plan to pay such dividend or
         distribution, the Conversion Price then in effect hereunder, if changed
         to reflect such dividend or distribution, shall upon the legal
         abandonment of such plan be changed to the Conversion Price which would
         have been in effect at the time of such abandonment (after giving
         effect to all other adjustments not so legally abandoned pursuant to
         the provisions of this Article Seventeen) had such dividend or
         distribution never been declared.

                  (10) Notwithstanding any other provision of this Section 1704,
         no adjustment to the Conversion Price shall reduce the Conversion Price
         below the then par value per share of the Common Stock of the Company,
         and any such purported adjustment shall instead reduce the Conversion
         Price to such par value. Notwithstanding the foregoing sentence, the
         Company hereby covenants that it will from time to time take all such
         action as may be required to assure that the par value per share of the
         Common Stock is at all times equal to or less than the Conversion
         Price.

                  (11) In the event that this Article Seventeen requires
         adjustments to the Conversion Price under more than one of paragraphs
         (1), (2), (3) or (4) of this Section 1704, and the record or effective
         dates for the transaction giving rise to such adjustments shall occur
         on the same date, then such adjustments shall be made by applying (to
         the extent they are applicable), first, the provisions of paragraph (3)
         of this Section 1704, second, the provisions of paragraph (1) of this
         Section 1704, third, the provisions of paragraph (4) of this Section
         1704 and, fourth, the provisions of paragraph (2) of this Section 1704.
         Anything herein to the contrary notwithstanding, no single event shall
         require or result in duplicative adjustments in the Conversion Price
         pursuant to this Section 1704. After an adjustment to the Conversion
         Price under this Article Seventeen, any subsequent event requiring an
         adjustment under this Article Seventeen shall cause an adjustment to
         the Conversion Price as so adjusted. If, after an adjustment, a Holder
         of a Security upon conversion of such Security receives shares of two
         or more classes of Capital Stock of the Company, the Conversion Price
         shall thereafter be subject to adjustment upon the occurrence of an
         action taken with respect


                                       94
<PAGE>   102
         to any such class of Capital Stock as is contemplated by this Article
         Seventeen with respect to the Common Stock in this Article Seventeen.

         SECTION 1705. Notice of Adjustments of Conversion Price.

         Whenever the Conversion Price is adjusted as herein provided:

             (1) the Company shall compute the adjusted Conversion Price in
accordance with Section 1704 or Section 1711 and shall prepare an Officer's
Certificate setting forth the adjusted Conversion Price and showing in
reasonable detail the facts upon which such adjustment is based, and such
certificate shall forthwith be filed (with a copy to the Trustee) at each office
or agency maintained for the purpose of conversion of any Securities pursuant to
Section 1002; and

             (2) a notice stating that the Conversion Price has been adjusted
and setting forth the adjusted Conversion Price shall forthwith be required, and
as soon as practicable after it is required, such notice shall be mailed by the
Company to all Holders at their last addresses as they shall appear in the
Security Register.

         SECTION 1706. Notice of Certain Corporate Action.

         In case:

             (1) the Company shall take any action that would require a
Conversion Price adjustment pursuant to Section 1704 or Section 1711; or

             (2) there shall occur any reclassification of the Common Stock of
the Company (other than a subdivision or combination of its outstanding shares
of Common Stock), or any consolidation or merger to which the Company is a
party, or the sale, transfer or lease of all or substantially all of the assets
of the Company and for which approval of any stockholders of the Company is
required; or

             (3) there shall occur the voluntary or involuntary dissolution,
liquidation or winding up of the Company,

then the Company shall cause to be filed at each office or agency maintained for
the purpose of conversion of Securities pursuant to Section 1002, and shall
cause to be mailed to all Holders at their last addresses as they shall appear
in the Security Register, at least 10 days prior to the applicable record,
effective or expiration date hereinafter specified, a notice stating (x) the
date on which a record is to be taken for the purpose of any dividend,
distribution or granting of rights, warrants or options, or, if a record is not
to be taken, the date as of which the holders of Common Stock of record to be
entitled to such dividend, distribution, rights, options or warrants are to be
determined, or (y) the date on which such reclassification, consolidation,
merger, sale, transfer, dissolution, liquidation or winding up is expected to
become effective,


                                       95
<PAGE>   103
and, if applicable, the date as of which it is expected that holders of Common
Stock of record shall be entitled to exchange their shares of Common Stock for
securities, cash or other property deliverable upon such reclassification,
consolidation, merger, sale, transfer, dissolution, liquidation or winding up.

         SECTION 1707. Company to Reserve Common Stock.

         The Company shall at all times reserve and keep available, free from
preemptive rights, out of its authorized but unissued Common Stock, for the
purpose of effecting the conversion of Securities, a number of shares of Common
Stock for the conversion of all outstanding Securities of any series which is
convertible into Common Stock.

         SECTION 1708. Taxes on Conversion.

         The Company will pay any and all taxes that may be payable in respect
of the issue or delivery of shares of Common Stock on conversion of Securities
pursuant hereto. The Company shall not, however, be required to pay any tax
which may be payable in respect of any transfer involved in the issue and
delivery of shares of Common Stock in a name other than that of the Holder of
the Security or Securities to be converted, and no such issue or delivery shall
be made unless and until the Person requesting such issue has paid to the
Company the amount of any such tax, or has established to the satisfaction of
the Company that such tax has been paid.

         SECTION 1709. Covenants as to Common Stock.

         The Company covenants that all shares of Common Stock which may be
issued upon conversion of Securities will upon issue be duly and validly issued,
fully paid and nonassessable, free of preemptive or any similar rights, and,
except as provided in Section 1708, the Company will pay all taxes, liens and
charges with respect to the issue thereof.

         The Company will endeavor promptly to comply with all Federal and state
securities laws regulating the offer and delivery of shares of Common Stock upon
conversion of Securities, if any, and will list or cause to have quoted such
shares of Common Stock on each national securities exchange or in the
over-the-counter market or such other market on which the Common Stock is then
listed or quoted.

         SECTION 1710. Cancellation of Converted Securities.

         All Securities delivered for conversion shall be delivered to the
Trustee to be cancelled by or at the direction of the Trustee, which shall
dispose of the same as provided in Section 309.


                                       96
<PAGE>   104
         SECTION 1711. Provisions in Case of Consolidation, Merger or Sale of
                       Assets; Special Distributions.

         If any of the following shall occur, namely: (i) any reclassification
or change of outstanding shares of Common Stock issuable upon conversion of
Securities (other than a change in par value, or from par value to no par value,
or from no par value to par value, or as a result of a subdivision or
combination), (ii) any consolidation or merger to which the Company is a party
other than a merger in which the Company is the continuing corporation and which
does not result in any reclassification of, or change (other than a change in
name, or par value, or from par value to no par value, or from no par value to
par value or as a result of a subdivision or combination) in, outstanding shares
of Common Stock or (iii) any sale or conveyance of all or substantially all of
the property or business of the Company as an entirety, then the Person formed
by such consolidation or resulting from such merger or which acquires such
properties or assets, as the case may be, shall as a condition precedent to such
transaction execute and deliver to the Trustee a supplemental indenture
providing that the Holder of each Security then outstanding shall have the right
thereafter, during the period such Security shall be convertible as specified in
Section 1701, to convert such Security only into the kind and amount of
securities, cash and other property receivable, if any, upon such consolidation,
merger, sale, transfer or lease by a holder of the number of shares of Common
Stock of the Company into which such Security might have been converted
immediately prior to such consolidation, merger, sale, transfer or lease;
provided that the kind and amount of securities, cash and other property so
receivable shall be determined on the basis of the following assumptions. The
holder of Common Stock referred to in the foregoing sentence:

         (1)      is not (a) a Person with which the Company consolidated, (b) a
                  Person into which the Company merged or which merged into the
                  Company, or (c) a Person to which such sale, transfer or lease
                  was made (any Person described in the foregoing clauses (a),
                  (b), or (c), hereinafter referred to as a "Constituent
                  Person"), or (d) an Affiliate of a Constituent Person; and

         (2)      failed to exercise his rights of election, if any, as to the
                  kind or amount of securities, cash and other property
                  receivable upon such consolidation, merger, sale, transfer or
                  lease (provided that if the kind or amount of securities, cash
                  and other property receivable upon such consolidation, merger,
                  sale transfer or lease is not the same for each share of
                  Common Stock of the Company in respect of which such rights of
                  election shall not have been exercised, then for the purpose
                  of this Section 1711 the kind and amount of securities, cash
                  and other property receivable upon such consolidation, merger,
                  sale, transfer or lease shall be deemed to be the kind and
                  amount so receivable per share by a plurality of such shares
                  of Common Stock).


                                       97
<PAGE>   105
         Such supplemental indenture shall provide for adjustments which, for
events subsequent to the effective date of such supplemental indenture, shall be
as nearly equivalent as may be practicable to the adjustments provided for in
this Article Seventeen. If, in the case of any such consolidation, merger, sale
transfer or lease the stock or other securities and property (including cash)
receivable thereupon by a holder of Common Stock includes shares of stock or
other securities and property of a corporation other than the successor or
purchasing corporation, as the case may be, in such consolidation, merger, sale,
transfer or lease then such supplemental indenture shall also be executed by
such other corporation and shall contain such additional provisions to protect
the interests of the Holders of the Securities as the Board of Directors of the
Company shall reasonably consider necessary by reason of the foregoing. The
above provisions of this Section 1711 shall similarly apply to successive
consolidations, mergers, sales, transfers or leases.

         In the event the Company shall execute a supplemental indenture
pursuant to this Section 1711, the Company shall promptly file with the Trustee
an Officers' Certificate briefly stating the reasons therefor, the kind or
amount of shares of stock or securities or property (including cash) receivable
by Holders of the Securities upon the conversion of their Securities after any
such reclassification, change, consolidation, merger, sale, transfer or lease
and any adjustment to be made with respect thereto.

         If the Company makes a distribution to all holders of its Common Stock
that constitutes an Unadjusted Distribution pursuant to the last sentence of
paragraph (4) of Section 1704, then, from and after the record date for
determining the holders of Common Stock entitled to receive such distribution
(the "Distribution Record Date"), a Holder of a Security who converts such
Security in accordance with the provisions of this Indenture shall, upon
conversion, be entitled to receive, in addition to the shares of Common Stock
into which the Security is convertible, the kind and amount of evidences of
indebtedness, shares of Capital Stock, or other assets or subscription rights or
warrants, as the case may be, comprising the distribution that such Holder would
have received if such Holder had converted the Security immediately prior to the
Distribution Record Date.

         SECTION 1712. Trustee Adjustment Disclaimer; Company Determination
                       Final.

         The Trustee has no duty to determine when an adjustment under this
Article Seventeen should be made, how it should be made or what it should be.
The Trustee has no duty to determine whether a supplemental indenture under
Section 1711 need be entered into or whether any provisions of any supplemental
indenture are correct. The Trustee shall not be accountable for and makes no
representation as to the validity or value of any securities or assets issued
upon conversion of Securities. The Trustee shall not be responsible for the
Company's failure to comply with this Article Seventeen. Any determination that
the Company or the Board of Directors must make pursuant to this Article
Seventeen is conclusive, absent manifest error.


                                       98
<PAGE>   106
         SECTION 1713. When No Adjustment Required.

             (a) Except as expressly set forth in Section 1704, no adjustment in
the Conversion Price shall be made because the Company issues, in exchange for
cash, property or services, shares of its Common Stock, or any securities
convertible into or exchangeable for shares of its Common Stock, or securities
(including warrants, rights and options) carrying the right to subscribe for or
purchase shares of its Common Stock or such convertible or exchangeable
securities.

             (b) Notwithstanding anything herein to the contrary, no adjustment
in the Conversion Price shall be made pursuant to Section 1704 in respect of any
dividend or distribution if the Holders may participate therein (on a basis to
be determined in good faith by the Board of Directors) and receive the same
consideration they would have received if they had converted the Securities
immediately prior to the record date with respect to such dividend or
distribution.

         SECTION 1714. Equivalent Adjustments.

         In the event that, as a result of an adjustment made pursuant to
Section 1704 above, the holder of any Security thereafter surrendered for
conversion shall become entitled to receive any shares of Capital Stock of the
Company other than shares of its Common Stock, thereafter the Conversion Price
of such other shares so receivable upon conversion of any Securities shall be
subject to adjustment from time to time in a manner and on terms as nearly
equivalent as practicable to the provisions with respect to Common Stock
contained in this Article Seventeen.

any time by the Company and the Trustee with the consent of the Holders of not

provisions of the Indenture. Furthermore, provisions in the Indenture permit the
Holders of not less than a majority of the aggregate principal amount, in
certain instances, of the Outstanding Securities of any series to waive, on

on this Security are payable, 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 Securities, of authorized
denominations and for the same aggregate principal amount, will be issued to the
designated transferee or transferees.

[without coupons] in denominations of $_______ and any integral multiple
thereof.

         No service charge shall be made for any such registration of transfer

any tax or other governmental charge payable in connection therewith,

Trustee nor any such agent shall be affected by notice to the contrary.

or Make-Whole Amount, if any, or the interest on this Security, or for any claim
based hereon, or otherwise in respect hereof, or based on or in respect of the
Indenture or any indenture supplemental thereto, against any past, present or
future stockholder, employee, officer or director, as such, of the Company or of
any successor, either directly or through the Company or any successor, whether
by virtue of any constitution, statute or rule of law or by the enforcement of
any assessment or penalty or otherwise, all such liability being, by the
acceptance hereof and as part of the consideration for the issue hereof,
expressly waived and released.

         The Indenture and the Securities shall be governed by and construed in
accordance with the laws of [the State of New York] applicable to agreements
made and to be performed entirely in such State.

        Re:    Legality of Securities to be Registered
               under Registration Statement on Form S-3

Ladies and Gentlemen:

        This opinion is delivered in our capacity as counsel to Bay Apartment
Communities, Inc., a Maryland corporation (the "Company"), in connection with
the Company's registration statement on Form S-3 (the "Registration Statement")
filed with the Securities and Exchange Commission under the Securities Act of
1933, as amended, which relates to the sale from time to time of an
indeterminate amount of debt securities ("Debt Securities"), shares of preferred
stock, par value $.01 per share ("Preferred Stock"), shares of common stock, par
value $.01 per share ("Common Stock"), or any combination of Debt Securities,
Preferred Stock and Common Stock (collectively, the "Securities"), having a
maximum aggregate public offering price of $600,000,000. The Registration
Statement provides that the Securities may be offered separately or together, in
separate series, in amounts, at prices and on terms to be set forth in one or
more prospectus supplements (each a "Prospectus Supplement") to the prospectus
contained in the Registration Statement.

        We have examined the Articles of Incorporation of the Company, as
amended and on file with the Maryland State Department of Assessments and
Taxation, the Bylaws of the Company, as amended, such records of corporate
proceedings of the Company as we have deemed appropriate for the purposes of
this opinion, the Registration Statement and the exhibits thereto.

        Based upon the foregoing, we are of the opinion that when the Securities
are specifically authorized for issuance by the Company's Board of Directors or
an authorized committee thereof (the "Authorizing Resolution"), upon receipt by
the Company of the full consideration therefor as provided in the Authorizing
Resolution and upon the issuance of the Securities as described in the
Registration Statement and a Prospectus Supplement that is consistent with the
Authorizing Resolution, the Securities will be legally issued, fully paid and
nonassessable.

                                       36

        We hereby consent to being named as counsel to the Company in the
Registration Statement, to the references therein to our firm under the caption
"Legal Matters" and to the inclusion of this opinion as an exhibit to the
Registration Statement.

                                           Very truly yours,

Apartment Communities, Inc. (the "Company") in connection with the registration
of $600,000,000 aggregate market value of the Company's Debt Securities,
Preferred Stock and Common Stock pursuant to the Company's Registration
Statement on Form S-3 (the "Registration Statement") to be filed with the
Securities and Exchange Commission. This opinion relates to the Company's
qualification for federal income tax purposes as a real estate investment trust
(a "REIT") under the Internal Revenue Code of 1986, as amended (the "Code"), for
taxable years commencing with the Company's taxable year ended December 31,
1994.

         We have relied upon the representations of an officer of the Company, a
copy of which is attached hereto, regarding the manner in which the Company has
been and will continue to be owned and operated and the continued accuracy of
such representations through the date of this letter. We assume that the Company
has been and will be operated in accordance with applicable laws and the terms
and conditions of applicable documents, and that the descriptions of the Company
and its investments, and the proposed investments, activities, operations, and
governance of the Company set forth in the Registration Statement continue to be
true. Capitalized terms not otherwise defined herein shall have the meaning
ascribed to such terms in the Registration Statement. In addition, we have
relied on certain additional facts and assumptions described below.

         In rendering the following opinion, we have examined the Company's
Articles of Incorporation, as amended, the By-Laws, as amended, its federal
income tax returns for the taxable years ended December 31, 1994, December 31,
1995, and December 31, 1996, each on Form 1120-REIT, and such other records,
certificates and documents as we have deemed necessary or appropriate for
purposes of rendering the opinion set forth herein.

         In rendering the opinion set forth herein, we have assumed (i) the
genuineness of all signatures on documents we have examined, (ii) the
authenticity of all documents submitted to us as originals, (iii) the conformity
to the original documents of all documents submitted to us as copies, (iv) the
conformity of final documents to all documents submitted to us as drafts, (v)
the authority and capacity of the individual or individuals who executed any
such documents on behalf of any person, (vi) the accuracy and completeness of
all records made available to us, and (vii) the factual accuracy of all
representations, warranties, and other statements made by all parties. We have
also assumed, without investigation, that all documents, certificates,
representations, warranties, and covenants on which we have relied in rendering
the opinion set forth below and that were given or dated earlier than the date
of this letter continue to remain accurate, insofar as relevant to the opinion
set forth herein, from such earlier date through and including the date of this
letter.

         The opinion set forth below is based upon the Code, the Income Tax
Regulations and Procedure and Administration Regulations promulgated thereunder
and existing administrative and judicial interpretations thereof, all as they
exist at the date of this letter. All of the foregoing statutes, regulations,
and interpretations are subject to change, in some circumstances with
retroactive effect; any changes to the foregoing authorities might result in
modification of our opinion contained herein.

         Based upon and subject to the foregoing, and provided that the Company
continues to meet the applicable asset composition, source of income,
shareholder diversification, distribution, record keeping and other requirements
of the Code necessary for a corporation to qualify as a REIT, we are of the
opinion that commencing with the taxable year ending December 31, 1994, the form
of organization of the Company and its operations are such as to enable the
Company to qualify as a "real estate investment trust" under the applicable
provisions of the Code.

         We express no opinions other than those expressly set forth herein.
Furthermore, the Company's qualification as a REIT will depend on the Company
meeting, in its actual operations, the applicable asset composition, source of
income, shareholder diversification, distribution, record keeping and other
requirements of the Code necessary for a corporation to qualify as a REIT. We
will not review these operations, and no assurance can be given that the actual
operations of the Company and its affiliates will meet these requirements or the
representations made to us with respect thereto. Our opinion is not binding on
the Internal Revenue Service (the "IRS"), and the IRS may disagree with the
opinion contained herein. Except as specifically discussed above, the opinion
expressed herein is based upon the law as it currently exists. Consequently,
future changes in the law may cause the federal income tax
